PRELIMINARY — SUBJECT TO COMPLETION, DATED , 2022

PROXY STATEMENT FOR SPECIAL MEETING OF

DYNAMICS SPECIAL PURPOSE CORP.

PROSPECTUS FOR 26,000,000 SHARES OF CLASS A COMMON STOCK

All of the members of the board of directors of Dynamics Special Purpose Corp., a Delaware corporation (“DYNS”), voting on the transaction approved the Business Combination Agreement, dated as of December 19, 2021 (as amended from time to time, the “Business Combination Agreement”), as amended on February 12, 2022 by Amendment No. 1 to Business Combination Agreement, by and among DYNS, Explore Merger Sub, Inc., a Delaware corporation and wholly-owned subsidiary of DYNS (“Merger Sub”), and Senti Biosciences, Inc., a Delaware corporation (“Senti”), pursuant to which Merger Sub will merge with and into Senti, with Senti surviving as a wholly owned subsidiary of DYNS (the “Business Combination”). In connection with the consummation of the Business Combination, DYNS will change its corporate name to “Senti Biosciences, Inc.” In this proxy statement/prospectus, when we refer to “Senti,” we mean Senti Biosciences, Inc. prior to the consummation of the Business Combination, and when we refer to “New Senti” or the “Combined Company” we mean DYNS, under its new corporate name after the consummation of the Business Combination.

At the effective time of the Business Combination (the “Effective Time”), (i) each outstanding share of Senti common stock will be cancelled and converted into the right to receive a number of shares of Class A Common Stock equal to the Exchange Ratio (as defined in this proxy statement/prospectus); (ii) each outstanding share of Senti preferred stock will be cancelled and converted into the right to receive a number of shares of Class A Common Stock equal to (A) the aggregate number of shares of Senti common stock that would be issued upon conversion of the shares of Senti preferred stock based on the applicable conversion ratio immediately prior to the Effective Time, multiplied by (B) the Exchange Ratio; and (iii) each outstanding Senti option will be converted into an option to purchase a number of shares of Class A Common Stock equal to (A) the number of shares of Senti common stock subject to such option immediately prior to the Effective time, multiplied by (B) the Exchange Ratio, at an exercise price per share equal to the current exercise price per share for such option divided by the Exchange Ratio; in each case, rounded down to the nearest whole share, and rounded up to the nearest whole cent in the case of the exercise price of the Senti options. Holders of shares of Senti common stock and Senti preferred stock may also be eligible to receive up to an aggregate of 2,000,000 shares of Class A Common Stock based on the share price of the Class A Common Stock following the Business Combination or, in some circumstances, upon a change of control of New Senti. See the section titled “

Proposal 1: The Business Combination Proposal

.” Based on an assumed closing date of 2022 for the Business Combination, the Exchange Ratio is approximately . Based on this Exchange Ratio, the total number of shares of Class A Common Stock expected to be issued in connection with the Business Combination (not including shares that will be issuable upon exercise of outstanding stock options) is approximately shares, and these shares are expected to represent approximately % or % of the issued and outstanding shares of Class A Common Stock immediately following the closing of the PIPE Investment (as defined in this proxy statement/prospectus) and the Business Combination, assuming no redemptions occur and maximum redemptions occur, respectively, and assuming that no shares of Class A Common Stock subject to Non-Redemption Agreements (as defined in this proxy statement/prospectus) are redeemed. Please see the section of the accompanying proxy statement/prospectus entitled

“Unaudited Pro Forma Condensed Combined Financial Information”

for further information regarding what constitutes a “maximum redemption” scenario.

Proposals to approve the Business Combination Agreement and the other matters discussed in this proxy statement/prospectus will be presented for approval by DYNS’s stockholders at the special meeting of stockholders of DYNS (the “Special Meeting”) scheduled to be held on , 2022, in virtual format.

DYNS’s Class A Common Stock is currently listed on The Nasdaq Capital Market (“Nasdaq”) under the symbol “DYNS.” DYNS intends to apply to continue the listing of the shares of Class A Common Stock effective upon the consummation of the Business Combination on Nasdaq under the proposed symbol “SNTB.” No shares will trade on Nasdaq under the symbol “DYNS” following the consummation of the Business Combination. It is a condition of the consummation of the Business Combination that the Class A Common Stock is approved for listing on Nasdaq (subject only to official notice of issuance thereof), but there can be no assurance such listing condition will be met. If such listing condition is not met, the Business Combination will not be consummated unless the listing condition set forth in the Business Combination Agreement is waived by the parties to that agreement.

DYNS is an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, as amended, and has elected to comply with certain reduced public company reporting requirements.

(iii)

each outstanding Senti option (whether vested or unvested) will be converted into an option to purchase a number of shares of Class A Common Stock (rounded down to the nearest whole share) equal to (A) the number of shares of Senti common stock subject to such option immediately prior to the Effective Time, multiplied by (B) the Exchange Ratio, at an exercise price per share equal to the current exercise price per share for such option divided by the Exchange Ratio (rounded up to the nearest whole cent); and

Table of Contents

non-binding

advisory basis, the following material differences between the Proposed Charter and the Current Charter, which are being presented pursuant to guidance of the Securities and Exchange Commission as seven separate

sub-proposals

(the “Advisory Charter Amendment Proposals”):

(e)

Advisory Charter Proposal E — to provide that certain amendments to provisions of the Proposed Charter will require the approval of at least 75% of the Combined Company’s then-outstanding shares of capital stock entitled to vote on such amendment and of each class entitled to vote thereon as a class;

(f)

Advisory Charter Proposal F — to make the Combined Company’s corporate existence perpetual instead of requiring DYNS to be dissolved and liquidated 24 months following the closing of DYNS’s initial public offering (the “Initial Public Offering”), and to omit from the Proposed Charter the various provisions applicable only to special purpose acquisition companies; and

(g)

Advisory Charter Proposal G — to remove the provision that allows stockholders to act by written consent as opposed to holding a stockholders meeting.

to approve, assuming the Business Combination Proposal is approved and adopted, for purposes of complying with the applicable provisions of Nasdaq Listing Rule 5635, (a) the issuance of up to 26,000,000 shares of Class A Common Stock in connection with the Business Combination, which amount will be determined as described in more detail in the accompanying proxy statement/prospectus, and (b) the issuance of an aggregate of 6,680,000 shares of Class A Common Stock in a private placement (the “PIPE Investment”) concurrent with the Business Combination (the “Nasdaq Stock Issuance Proposal”);

to approve, assuming the Business Combination Proposal is approved and adopted, the appointment of seven directors who, upon consummation of the Business Combination, will become directors of the Combined Company (the “Director Election Proposal”);

to approve, assuming the Business Combination Proposal is approved and adopted, the Incentive Plan, a copy of which is attached to the accompanying proxy statement/prospectus as

Annex

, which will become effective as of and contingent on the consummation of the Business Combination (the “Incentive Plan Proposal”);

to approve, assuming the Business Combination Proposal is approved and adopted, the ESPP, a copy of which is attached to the accompanying proxy statement/prospectus as

Annex D

, which will become effective as of and contingent on the consummation of the Business Combination (the “ESPP Proposal”); and

to approve a proposal to adjourn the Special Meeting to a later date or dates if it is determined that more time is necessary or appropriate, in the judgment of the board of directors of DYNS or the officer presiding over the Special Meeting, for DYNS to consummate the Business Combination (the “Adjournment Proposal”).

Only holders of record of Class A Common Stock and Class B Common Stock of DYNS (collectively, the “DYNS Common Stock”) at the close of business on , 2022 (the “Record Date”) are entitled to notice of

Table of Contents

the Special Meeting and to vote at the Special Meeting and any adjournments or postponements of the Special Meeting. A complete list of DYNS stockholders of record entitled to vote at the Special Meeting will be available for ten (10) days before the Special Meeting at the principal executive offices of DYNS for inspection by stockholders during ordinary business hours for any purpose germane to the Special Meeting.

Pursuant to the Current Charter, DYNS is providing its public stockholders (“Public Stockholders”) with the opportunity to redeem, upon the Closing, the shares of Class A Common Stock (the “Public Shares”) issued in the Initial Public Offering then held by them for cash equal to their pro rata share of the aggregate amount on deposit (as of two business days prior to the Closing) in the trust account (the “Trust Account”) that holds the proceeds (including interest but less franchise and income taxes payable) of the Initial Public Offering. For illustrative purposes, based on funds in the Trust Account of approximately $ on the Record Date, the estimated per share redemption price would have been approximately .

Public Stockholders may elect to redeem Public Shares even if they vote for the Business Combination Proposal

. A Public Stockholder, together with any of his, her or its affiliates or any other person with whom he, she or it is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended), will be restricted from redeeming in the aggregate his, her or its shares or, if part of such a group, the group’s shares, with respect to 20% or more of the Public Shares issued in the Initial Public Offering. DYNS’s Sponsor and DYNS’s other initial stockholders have agreed to waive their redemption rights with respect to any Founder Shares and Private Placement Shares (each as defined in the accompanying proxy statement/prospectus) and any Public Shares they may hold, and the Sponsor has also agreed to waive its redemption rights with respect to any other equity securities it holds in connection with the Closing, and such shares will be excluded from the pro rata calculation used to determine the

per-share

redemption price. The Sponsor and DYNS’s other initial stockholders have agreed to vote any Founder Shares, Private Placement Shares and Public Shares owned by them, and the Sponsor has also agreed to vote any other equity securities in favor of the Business Combination Proposal, which represent approximately % of the voting power of DYNS as of the Record Date. These holders have also agreed to vote their shares in favor of all other Proposals being presented at the Special Meeting.

Pursuant to DYNS’s bylaws, a majority of the shares of DYNS Common Stock entitled to vote, represented at the Special Meeting or by proxy, will constitute a quorum for the transaction of business at the Special Meeting. Under the Delaware General Corporation Law, shares that are voted “abstain” or “withheld” are counted as present for purposes of determining whether a quorum is present at the Special Meeting. Because the Proposals are

“non-discretionary”

items, your broker will not be able to vote uninstructed shares for any of the Proposals. As a result, if you do not provide voting instructions, a broker

“non-vote”

will be deemed to have occurred for each of the Proposals. Broker

“non-votes”

will not be counted as present for purposes of determining whether a quorum is present.

The approval of the Business Combination Proposal requires the affirmative vote of the holders of a majority of the shares of DYNS Common Stock cast in respect of that Proposal and entitled to vote thereon at the Special Meeting, voting together as a single class. The approval of each of the Nasdaq Stock Issuance Proposal, the Incentive Plan Proposal, the ESPP Proposal, the Adjournment Proposal and each of the Advisory Charter Amendment Proposals also requires the affirmative vote of the holders of a majority of the shares of DYNS Common Stock cast in respect of the relevant Proposal and entitled to vote thereon at the Special Meeting, voting together as a single class. The approval of the Charter Amendment Proposal requires the affirmative vote of a majority of the issued and outstanding shares of each of the Class A Common Stock and Class B Common Stock, voting separately, as well as the vote of a majority of the issued and outstanding shares of Class A Common Stock and Class B Common Stock, voting together as a single class.

The approval of the Director Election Proposal requires a plurality vote of the shares of DYNS Class B Common Stock cast in respect of that Proposal and entitled to vote thereon at the Special Meeting. “Plurality” means that the individuals who receive the largest number of votes cast “FOR” are elected as directors. Consequently, any shares not voted “FOR” a particular nominee (whether as a result of an abstention, a direction to withhold authority or a broker

non-vote)

will not be counted in the nominee’s favor.

If the Business Combination Proposal is not approved, the Charter Amendment Proposal, the Advisory Charter Amendment Proposals, the Nasdaq Stock Issuance Proposal, the Director Election Proposal, the

Table of Contents

Incentive Plan Proposal and the ESPP Proposal will not be presented to the DYNS stockholders for a vote. The approval of the Business Combination Proposal, the Charter Amendment Proposal, the Nasdaq Stock Issuance Proposal, the Director Election Proposal, the Incentive Plan Proposal and the ESPP Proposal are preconditions to the Closing.

As of the Record Date, there was approximately $ in the Trust Account. Each redemption of Public Shares by Public Stockholders will decrease the amount in the Trust Account. DYNS will not redeem Public Shares in an amount that would cause it to have net tangible assets of less than $5,000,001.

Your attention is directed to the proxy statement/prospectus accompanying this notice (including the Annexes thereto) for a more complete description of the proposed Business Combination and related transactions and each of the Proposals. We encourage you to read this proxy statement/prospectus carefully. If you have any questions or need assistance voting your shares, please call our proxy solicitor, at or email at .

You should carefully read this entire proxy statement/prospectus, including all of the accompanying financial statements and the attached annexes, for a more complete understanding of the matters to be considered at the Special Meeting.

•

DYNS is a special purpose acquisition company formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses.

•

On May 28, 2021, DYNS completed its Initial Public Offering of 23,000,000 shares of Class A Common Stock at a price of $10.00 per share, generating proceeds of $230,000,000 before underwriting discounts and expenses. Simultaneously with the closing of the Initial Public Offering, DYNS closed the Concurrent Private Placement of 715,500 shares of Class A Common Stock at a price of $10.00 per share to the Sponsor, generating proceeds of $7,155,000.

•

Senti’s mission is to create a new generation of smarter therapies that can outmaneuver complex diseases in ways previously not implemented by conventional medicines. To accomplish this mission, Senti has built a synthetic biology platform that it believes may enable it to program next-generation cell and gene therapies with what it refers to as “gene circuits.” These gene circuits, which Senti created from novel and proprietary combinations of genetic parts, are designed to reprogram cells with biological logic to sense inputs, compute decisions and respond to their respective cellular environments. Senti aims to design and optimize gene circuits through its Design-Build-Test-Learn Engine, or DBTL Engine, to improve the “intelligence” of cell and gene therapies in order to enhance their therapeutic effectiveness against a broad range of diseases that conventional medicines are unable to address. Senti’s gene circuit platform technologies can be applied in a modality-agnostic manner, with applicability to natural killer (NK) cells, T cells, tumor infiltrating lymphocytes (TILs), stem cells including Hematopoietic Stem Cells (HSCs), in vivo gene therapy and messenger ribonucleic acid (mRNA). All of Senti’s current product candidates are in preclinical development. Senti’s lead product candidates utilize allogeneic chimeric antigen receptor (CAR) NK cells outfitted with its gene circuit technologies in several oncology indications with currently high unmet need. Subject to the successful identification of lead product candidates and the completion of IND-enabling studies, Senti expects to file investigational new drug applications, or INDs, for multiple product candidates starting in 2023.

•

On December 19, 2021, DYNS, Senti and Merger Sub entered into the Business Combination Agreement. Under the terms of the Business Combination Agreement, the parties thereto will enter into a business combination transaction pursuant to which Merger Sub will merge with and into Senti, with Senti surviving as a wholly owned subsidiary of DYNS.

•

In accordance with and subject to the terms of the Business Combination Agreement, the consideration to be paid in connection with the Business Combination is $240,000,000, which will be paid as equity consideration to the Sellers. The Sellers may also be entitled to the Contingency Consideration. For more information regarding the consideration to be paid in connection with the Business Combination, please see the section entitled

“Summary of the Proxy Statement/Prospectus – Business Combination Consideration.”

Table of Contents

•

Concurrently with the execution of the Business Combination Agreement, DYNS entered into subscription agreements with the PIPE Investors in respect of the PIPE Investment, pursuant to which the PIPE Investors have collectively subscribed for 6,680,000 shares of Class A Common Stock for an aggregate purchase price equal to $66,800,000. The PIPE Investment will be consummated substantially concurrently with the Closing. It is anticipated that upon Closing:

•

the PIPE Investors will own approximately 11% of the outstanding DYNS Common Stock;

•

the Sellers will own approximately 39% of the outstanding DYNS Common Stock;

•

the Sponsor will own approximately 9% of the outstanding DYNS Common Stock; and

•

Public Stockholders will own approximately 41% of the outstanding DYNS Common Stock.

These levels of ownership interest: (i) assume that no Public Shares are elected to be redeemed in connection with the Business Combination, (ii) assume no exercise of any options to purchase Class A Common Stock that will be outstanding immediately following the Business Combination, whether such options are issued under the Incentive Plan or otherwise, (iii) excludes the Contingency Consideration, and (iv) exclude the issuance of any shares in connection with the Incentive Plan and the ESPP following the Business Combination. If the actual facts are different from these assumptions, then the levels of ownership interest set forth above will be different. For more information, please see the section entitled

“Unaudited Pro Forma Condensed Combined Financial Information.”

•

On February 12, 2022, DYNS, Merger Sub, and Senti entered into Amendment No.1 to Business Combination Agreement, to, among other things: (i) clarify section 5.7 of the Business Combination Agreement with respect to certain parameters of the Incentive Plan, and (ii) restructure certain option grants made to Senti employees at the time the Business Combination Agreement was signed, to (a) acknowledge that certain of such employees’ option award agreements reflect the fact that their option grants, which are for a number of shares of Senti common stock, are subject to adjustment, and (b) provide that certain of such employees’ options will commence vesting on the grant date (being the date the Business Combination Agreement was signed) while other employees’ options will commence vesting on the Closing Date.

•

In evaluating the Business Combination, our Board considered various factors in determining whether to approve the Business Combination Agreement. For more information about our decision-making process, as well as other factors, uncertainties and risks considered, see the section entitled “

Proposal 1: The Business Combination Proposal

— The Board’s Reasons for Approval of the Business Combination

.”

•

Pursuant to the Current Charter, holders of Public Shares may request that we redeem all or a portion of their Public Shares for cash if the Business Combination is consummated. Holder of Public Shares may elect to redeem their Public Shares even if they vote “FOR” the proposal to approve the Business Combination, or any other Proposal. If the Business Combination is not consummated, the Public Shares will be returned to the respective holder or their broker, bank or other nominee. If the Business Combination is consummated, and if a holder of Public Shares properly exercises their right to redeem all or a portion of the Public Shares that they hold, including by timely delivering their shares to Continental, we will redeem such Public Shares for a

per-share

price, payable in cash, equal to the pro rata portion of the Trust Account, calculated as of two business days prior to the consummation of the Business Combination, including interest but less franchise and income taxes payable. For illustrative purposes, based on funds in the Trust Account of approximately $ on the Record Date, the estimated per share redemption price would have been approximately $10.00. If a holder of Public Shares properly exercises their redemption rights in full, then they will be electing to exchange all of their Public Shares for cash and will not own any shares of the Combined Company. Please see the section entitled

“Summary of the Proxy Statement/Prospectus—Redemption Rights of DYNS Stockholders

” for further information regarding the redemption rights of holders of Public Shares.

For further information, please see the section entitled

“Summary of the Proxy Statement/Prospectus—Additional Matters Being Voted On By DYNS Stockholders

. The approval of the Business Combination Proposal, the Charter Amendment Proposal, the Nasdaq Stock Issuance Proposal, the Director Election Proposal, Incentive Plan Proposal and the ESPP Proposal are preconditions to the Closing. Each of these Proposals is more fully described in this proxy statement/prospectus, which each DYNS stockholder is encouraged to read carefully and in its entirety.

•

Unless waived by the parties to the Business Combination Agreement, and subject to applicable law, the closing of the Business Combination is subject to a number of conditions set forth in the Business Combination Agreement, including, among others: (i) there being at least $150,000,000 in cash available at Closing; (ii) the registration statement of which this proxy statement/prospectus forms a part becoming effective in accordance with the Securities Act; (iii) customary bringdown conditions; and (iv) no material adverse effect of either DYNS or Senti having occurred. There can be no assurance that the parties to the Business Combination Agreement would waive any such provision of the Business Combination Agreement. For more information about the closing conditions to the Business Combination, please see the section entitled “

Proposal 1: The Business Combination Proposal.”

•

To assist with minimizing redemptions of shares of Class A Common Stock and satisfying the condition to Closing that here being at least $150,000,000 in available cash, on December 19, 2021, DYNS entered into non-redemption agreements (the “Non-Redemption Agreements”) with the Anchor Investors pursuant which such investors agreed to, among other things, not redeem the shares of Class A Common Stock beneficially owned by them as at such date and to not, subject to certain exceptions, transfer such shares of Class A Common Stock. These commitments apply in respect of 8,691,655 shares of Class A Common Stock in the aggregate. In connection with these commitments from the Anchor Investors, the Sponsor agreed to forfeit 965,728 Founder Shares and DYNS agreed to cancel such Founder Shares and concurrently issue to such investors an equivalent number of shares of Class A Common Stock, in each case, at or promptly following Closing. For more information about the Non-Redemption Agreements, please see the section entitled “Proposal 1: The Business Combination Proposal – Related Agreements – Non-Redemption Agreements.”

•

The proposed Business Combination, including our business following the Business Combination, involves numerous risks. For more information about these risks, please see the section entitled

“Risk Factors.”

•

When you consider the recommendation of our Board in favor of approval of the Business Combination Proposal and the other Proposals included herein, you should keep in mind that the Sponsor and our directors have interests in such Proposals that are different from, or in addition to, those of our stockholders generally. Our Board was aware of and considered these interests, among other matters, in evaluating and negotiating the Business Combination Agreement and the other transaction agreements and in recommending to our stockholders that they vote in favor of the Proposals presented at the Special Meeting, including the Business Combination Proposal. DYNS stockholders should take these interests into account in deciding whether to approve the Proposals presented at the Special Meeting, including the Business Combination Proposal. For further information, please see the section entitled “

QUESTIONS AND ANSWERS ABOUT THE PROPOSALS

The questions and answers below highlight only selected information from this proxy statement/prospectus and only briefly address some commonly asked questions about the Special Meeting and the Proposals to be presented at the Special Meeting, including with respect to the proposed Business Combination. The following questions and answers do not include all the information that may be important to DYNS stockholders. DYNS stockholders are urged to read this entire proxy statement/prospectus, including the Annexes and the other documents referred to herein.

QUESTIONS AND ANSWERS ABOUT THE BUSINESS COMBINATION

Q:	What is the Business Combination?

A:	DYNS and Senti have entered into the Business Combination Agreement, pursuant to which Merger Sub will merge with and into Senti, with Senti surviving the Business Combination as a wholly-owned subsidiary of DYNS.

Q:	Why am I receiving this proxy statement/prospectus?

DYNS and Senti have agreed to a Business Combination under the terms of the Business Combination Agreement that is described in this proxy statement/prospectus. A copy of the Business Combination Agreement is attached to this proxy statement/prospectus as

Annex

, and DYNS encourages its stockholders to read it in its entirety. DYNS’s stockholders are being asked to consider and vote upon a proposal to approve the Business Combination Agreement, which, among other things, provides for the Business Combination whereby Merger Sub will merge with and into Senti, with Senti surviving the Business Combination as a wholly-owned subsidiary of DYNS. See the section entitled “

Proposal 1: The Business Combination Proposal

.”

This document is a proxy statement because the Board is soliciting proxies using this proxy statement/prospectus from DYNS stockholders. It is a prospectus because DYNS, in connection with the Business Combination, is offering shares of Class A Common Stock in exchange for the outstanding shares of Senti common stock and Senti preferred stock. See the section entitled “

Proposal 1: The Business Combination Proposal.

”

Q:	What will Senti stockholders and holders of Senti options receive in the Business Combination?

A:	If the Business Combination is completed:

•

Each outstanding share of Senti common stock will be cancelled and converted into the right to receive a number of shares of Class A Common Stock equal to the Exchange Ratio (rounded down to the nearest whole share).

•

Each outstanding share of Senti preferred stock will be cancelled and converted into the right to receive a number of shares of Class A Common Stock equal to (A) the aggregate number of shares of Senti common stock that would be issued upon conversion of the shares of Senti preferred stock based on the applicable conversion ratio immediately prior to the Effective Time, multiplied by (ii) the Exchange Ratio (rounded down to the nearest whole share).

•

Each outstanding Senti option (whether vested or unvested) will be converted into an option to purchase a number of shares of Class A Common Stock (rounded down to the nearest whole share) equal to (A) the number of shares of Senti common stock subject to such option immediately prior to the Effective Time, multiplied by (B) the Exchange Ratio, at an exercise price per share equal to the current exercise price per share for such option divided by the Exchange Ratio (rounded up to the nearest whole cent).

The consideration described in the foregoing bullets is referred to collectively as the “Business Combination Consideration.” Based on the number of shares of Senti common stock and Senti

Table of Contents

preferred stock outstanding and the number of shares of Senti common stock underlying outstanding Senti options, in each case as of the Record Date, the total number of shares of Class A Common Stock expected to be issued as Business Combination Consideration is 24,000,000 shares. Following the closing of the Business Combination, the Sellers may also be eligible to receive the Contingency Consideration of up to an aggregate of 2,000,000 shares of Class A Common Stock. For further information, please see the section titled “

Proposal 1: The Business Combination Proposal — Structure of the Business Combination

.”

Q:	When do you expect the Business Combination to be completed?

It is currently anticipated that the Business Combination will be consummated promptly following the Special Meeting, which is set for , 2022; however, the Special Meeting could be adjourned, as described herein. DYNS cannot assure you of when or if the Business Combination will be completed, and it is possible that factors outside of the control of DYNS and Senti could result in the Business Combination being completed at a different time or not at all. DYNS must first obtain the approval of its stockholders for certain of the Proposals set forth in this proxy statement/prospectus.

Q:	What happens if the Business Combination is not consummated?

If DYNS does not complete the Business Combination with Senti, for whatever reason, DYNS will search for another target business with which to complete a business combination. If DYNS does not complete the Business Combination with Senti or another business combination by May 28, 2023 (or such later date as may be approved by DYNS stockholders in an amendment to its Current Charter), DYNS must redeem 100% of the Public Shares, at a

per-share

price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to DYNS to pay its franchise and income taxes (less up to $100,000 of such net interest to pay dissolution expenses), divided by the number of then-outstanding Public Shares. The Sponsor has waived any rights it may have with respect to any monies held in the Trust Account or any other asset of DYNS as a result of any liquidation of DYNS with respect to the Founder Shares and Private Placement Shares and, accordingly, in the event a business combination is not effected by DYNS in the required time period, the Founder Shares and Private Placement Shares held by the Sponsor would be worthless.

Q:	Did the Board obtain a third-party valuation or fairness opinion in determining whether or not to proceed with the Business Combination?

No, the Board did not obtain a third-party valuation or fairness opinion. Consequently, you have no assurance from an independent source that the price proposed to be paid for Senti is fair from a financial point of view.

Q:	Are there any other matters being presented to DYNS stockholders at the Special Meeting?

In addition to voting on the Business Combination Proposal, assuming it is approved and adopted, the stockholders of DYNS will vote on each of the other Proposals described in the section above entitled

“Summary Term Sheet.”

DYNS will hold the Special Meeting to consider and vote upon these Proposals. This proxy statement/prospectus contains important information about the proposed Business Combination and the other matters to be acted upon at the Special Meeting. Stockholders should read it carefully.

Consummation of the Business Combination is conditioned on approval of the Business Combination Proposal, the Charter Amendment Proposal, the Nasdaq Stock Issuance Proposal, the Director Election Proposal, Incentive Plan Proposal and the ESPP Proposal (and each such Proposal is cross-conditioned on the approval of such other Proposals). If any of these Proposals is not approved, the other Proposals will not be presented to stockholders for a vote.

The vote of stockholders is important. DYNS stockholders are encouraged to vote as soon as possible after carefully reviewing this proxy statement/prospectus.

Q:	What will happen to DYNS’s securities upon consummation of the Business Combination?

DYNS’s Class A Common Stock is currently listed on Nasdaq under the symbol “DYNS.” Upon the Closing, the Combined Company will have one class of common stock, which will be listed on Nasdaq under the symbol “SNTB.” Public Stockholders who do not elect to have their Public Shares redeemed for a pro rata share of the Trust Account need not submit Public Shares, and such shares of stock (which will be Class A Common Stock upon the Closing) will remain outstanding. Each outstanding share of Class B Common Stock, by its terms, will automatically convert into one share of Class A Common Stock upon the Closing.

Q:	Why is DYNS proposing the Business Combination?

A :	DYNS was organized to effect a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more businesses.

On May 28, 2021, DYNS completed its Initial Public Offering of shares of Class A Common Stock, at a price of $10.00 per share, raising total gross proceeds of $230 million. Since its Initial Public Offering, DYNS’s activity has been limited to the evaluation of business combination candidates.

decisions and respond to their respective cellular environments. Senti aims to design and optimize gene circuits through its Design-Build-Test-Learn Engine, or DBTL Engine, to improve the “intelligence” of cell and gene therapies in order to enhance their therapeutic effectiveness against a broad range of diseases that conventional medicines are unable to address. Senti’s gene circuit platform technologies can be applied in a modality-agnostic manner, with applicability to natural killer (NK) cells, T cells, tumor infiltrating lymphocytes (TILs), stem cells including Hematopoietic Stem Cells (HSCs),

in vivo

gene therapy and messenger ribonucleic acid (mRNA). All of Senti’s current product candidates are in preclinical development. Senti’s lead product candidates utilize allogeneic chimeric antigen receptor (CAR) NK cells outfitted with its gene circuit technologies in several oncology indications with currently high unmet need. Subject to the successful identification of lead product candidates and completion of IND- enabling studies, Senti expects to file investigational new drug applications, or INDs, for multiple product candidates starting in 2023.

Based on its due diligence investigations of Senti and the industry in which Senti operates, including the financial and other information provided by Senti in the course of the negotiations in connection with the Business Combination Agreement, DYNS believes that Senti has an appealing market opportunity and growth profile and a compelling valuation. As a result, DYNS believes that the Business Combination with Senti will provide DYNS stockholders with an opportunity to participate in the ownership of a company with significant value. See the section entitled “

Proposal 1: The Business Combination Proposal

— The Board’s Reasons for Approval of the Business Combination

.”

Q:	Do I have redemption rights?

A:	If you are a DYNS stockholder holding Public Shares, you have the right to demand that DYNS redeem your Public Shares for a pro rata portion of the cash held in the Trust Account. We sometimes refer to these rights to demand redemption of the Public Shares as “redemption rights.”

Notwithstanding the foregoing, a DYNS stockholder, together with any affiliate or any other person with whom such holder is acting in concert or as a “group” (as defined in Section 13(d)(3) of the Exchange Act), will be restricted from exercising redemption rights with respect to 20% or more of the Public Shares without the prior consent of DYNS.

Q:	How do I exercise my redemption rights?

A Public Stockholder may exercise redemption rights regardless of whether they vote on the Business Combination Proposal or if they are a stockholder on the Record Date. If you are a Public Stockholder and wish to exercise your redemption rights, you must demand that DYNS redeem your Public Shares for cash and deliver your Public Shares to DYNS’s transfer agent, Continental, at Continental Stock Transfer & Trust Company, One State Street Plaza, 30

Floor, New York, New York 10004, Attn: Mark Zimkind, physically or electronically using mzimkind@continentalstock.com, at least two business days before the Special Meeting, or , 2022. Rather than delivering your Public Shares directly to Continental, you may also deliver your Public Shares either physically or electronically through DTC to Continental at least two business days before the Special Meeting. Any Public Stockholder seeking redemption will be entitled to a full pro rata portion of the amount then in the Trust Account (which, for illustrative purposes, was $ , or $ per share, as of the Record Date), less any owed but unpaid franchise and income taxes. Such amount will be paid promptly upon consummation of the Business Combination. There are currently no owed but unpaid franchise or income taxes on the funds in the Trust Account.

Any request for redemption, once made by a Public Stockholder, may be withdrawn at any time prior to the time the vote is taken with respect to the Business Combination Proposal at the Special Meeting. If you deliver your Public Shares for redemption directly to Continental, or deliver your Public Shares either physically or electronically through DTC to Continental, and later decide prior to the Special Meeting not to elect redemption, you may request that Continental return the shares (physically or electronically). You may make such request by contacting Continental at the phone number or address set forth in this proxy statement/prospectus.

Table of Contents

Any written demand of redemption rights must be received by Continental at least two business days prior to the vote taken on the Business Combination Proposal at the Special Meeting. No demand for redemption will be honored unless the holder’s stock has been delivered (either physically or electronically) to Continental.

Q:	What is a Non-Redemption Agreement?

In an effort to reduce the number of redemptions of Class A Common Stock at Closing,

Non-Redemption

Agreements were entered into with the Anchor Investors. Pursuant to the agreements, the Anchor Investors agreed to, among other things, not redeem the shares of Class A Common Stock beneficially owned by them as at the date the Non-Redemption Agreements were signed and to not, subject to certain exceptions, transfer such shares of Class A Common Stock. These commitments apply in respect of 8,691,655 shares of Class A Common Stock in the aggregate. In connection with these commitments from the Anchor Investors, the Sponsor agreed to forfeit 965,728 Founder Shares and DYNS agreed to cancel such Founder Shares and concurrently issue to such investors an equivalent number of shares of Class A Common Stock, in each case, at or promptly following Closing.

Q:	Do I have appraisal rights if I object to the proposed Business Combination?

A:	No. DYNS stockholders do not have appraisal rights in connection with the proposed Business Combination under Delaware law.

Q:	What happens if a substantial number of stockholders vote in favor of the Business Combination Proposal and exercise redemption rights?

Public Stockholders may vote in favor of the Business Combination and still exercise their redemption rights and are not required to vote in any way to exercise their redemption rights. Accordingly, the Business Combination may be consummated even though the funds available from the Trust Account and the number of Public Shares are substantially reduced as a result of redemptions by Public Stockholders (however, the condition to the consummation of the Business Combination requiring that DYNS have at least $5,000,001 of net tangible assets may not be waived). Also, with fewer Public Shares and Public Stockholders, the trading markets for Class A Common Stock following the closing of the Business Combination may be less liquid than the market for Class A Common Stock was prior to the Business Combination and New Senti may not be able to meet the listing standards of a national securities exchange, including Nasdaq. In addition, with fewer funds available from the Trust Account, the capital infusion from the Trust Account into New Senti’s business will be reduced and New Senti may not be able to achieve its business plans.

Q:	How do the Sponsor and the officers and directors of DYNS intend to vote on the Proposals?

The Sponsor, as well as DYNS’s officers and directors, beneficially own and are entitled to vote an aggregate of approximately 21.9% of the outstanding DYNS Common Stock as of the Record Date. These holders have agreed to vote their shares in favor of the Business Combination Proposal. These holders have also agreed to vote their shares in favor of all other Proposals being presented at the Special Meeting.

Q:	What do I need to do now?

DYNS urges you to carefully read and consider the information contained in this proxy statement/prospectus, including the Annexes, and to consider how the Business Combination will affect you as a stockholder of DYNS. DYNS stockholders should then vote as soon as possible in accordance with the instructions provided in this proxy statement/prospectus and on the enclosed proxy card.

Q:	How do I vote?

A:	If you are a holder of record of DYNS Common Stock on the Record Date, you may vote virtually at the Special Meeting or by submitting a proxy for the Special Meeting. You may submit your proxy by

xiii

Table of Contents

completing, signing, dating and returning the enclosed proxy card in the accompanying

pre-addressed

postage paid envelope. If you hold your shares in “street name,” which means your shares are held of record by a broker, bank or nominee, you should contact your broker, bank or nominee to ensure that votes related to the shares you beneficially own are properly counted. In this regard, you must provide the broker, bank or nominee with instructions on how to vote your shares or, if you wish to attend the meeting and vote in person (which would include presence at a virtual meeting), obtain a legal proxy from your broker, bank or nominee.

If you do not give instructions to your brokerage firm, the brokerage firm will not be allowed to vote your shares with respect to the Proposals. The Proposals are

“non-discretionary”

items. Your broker may not vote for

non-discretionary

items, and those votes will be counted as broker

“non-votes.”

After obtaining a valid legal proxy from your broker, bank or nominee, to register to attend the Special Meeting, you must submit proof of your legal proxy reflecting the number of your shares along with your name and email address to Continental at proxy@continentalstock.com. Beneficial owners who

e-mail

a valid legal proxy will be issued a

12-digit

meeting control number that will allow them to register to attend and participate in the Special Meeting. Beneficial owners who wish to attend the Special Meeting online should contact Continental no later than , 2022 to obtain this information. Written requests can be emailed to [proxy@continentalstock.com].

Q:	If my shares are held in “street name,” will my broker, bank or nominee automatically vote my shares for me?

A:	No. Your broker, bank or nominee cannot vote your shares unless you provide instructions on how to vote in accordance with the information and procedures provided to you by your broker, bank or nominee.

Q:	May I change my vote after I have mailed my signed proxy card?

Yes. DYNS stockholders may send a later-dated, signed proxy card to Continental at the address set forth above so that it is received prior to the vote at the Special Meeting or attend the Special Meeting virtually and vote. DYNS stockholders also may revoke their proxy by sending a notice of revocation to Continental, which must be received prior to the vote at the Special Meeting.

Q:	What happens if I fail to take any action with respect to the Special Meeting?

If you fail to take any action with respect to the Special Meeting and the Business Combination is approved by stockholders and consummated, you will continue to be a holder of Class A Common Stock. As a corollary, failure to deliver (either physically or electronically) your stock certificate(s) to DYNS’s transfer agent, Continental, no later than two business days prior to the Special Meeting, means you will not have any right in connection with the Business Combination to exchange your Public Shares for a pro rata share of the funds held in the Trust Account. If you fail to take any action with respect to the Special Meeting and the Business Combination is not approved, you will continue to be a stockholder of DYNS.

Q:	What should I do with my share certificate(s)?

Those Public Stockholders who do not elect to have their Public Shares redeemed for a pro rata share of the funds held in the Trust Account need not submit their certificate(s). Public Stockholders who exercise their redemption rights must deliver their share certificate(s) to Continental (either physically or electronically) or through DTC to Continental at least two business days before the Special Meeting, as described above.

Q:	What should I do if I receive more than one set of voting materials?

A:	DYNS stockholders may receive more than one set of voting materials, including multiple copies of this proxy statement/prospectus and multiple proxy cards or voting instruction cards. For example, if you hold

Emerging Growth Company

DYNS is an “emerging growth company,” as defined under the JOBS Act. As an emerging growth company, DYNS is eligible to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies. These include, but are not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and the requirement to obtain stockholder approval of any golden parachute payments not previously approved.

The Business Combination Proposal

Pursuant to the Business Combination Agreement, a Business Combination between DYNS and Senti will be effected whereby Merger Sub will merge with and into Senti, with Senti surviving as a wholly-owned subsidiary of DYNS.

Table of Contents

After consideration of the factors identified and discussed in the section entitled “

Proposal 1: The Business Combination Proposal — The Board’s Reasons for Approval of the Business Combination

,” our Board concluded that the Business Combination met all of the requirements disclosed in the prospectus for our Initial Public Offering.

The terms and conditions of the Business Combination are contained in the Business Combination Agreement, which is attached to this proxy statement/prospectus as

Annex

and is incorporated by reference herein in its entirety. DYNS encourages you to read the Business Combination Agreement carefully, as it is the legal document that governs the Business Combination. For more information on the Business Combination Agreement, see the section entitled “

Proposal 1: The Business Combination Proposal

.”

Business Combination Consideration

Pursuant to the Business Combination Agreement:

•

Each outstanding share of Senti common stock held by the Sellers immediately before the Effective Time will be cancelled and converted into the right to receive a number of shares of Class A Common Stock equal to the Exchange Ratio (rounded down to the nearest whole share).

•

Each outstanding share of Senti preferred stock held by the Sellers immediately before the Effective Time will be cancelled and converted into the right to receive a number of shares of Class A Common Stock equal to (A) the aggregate number of shares of Senti common stock that would be issued upon conversion of the shares of Senti preferred stock based on the applicable conversion ratio immediately prior to the Effective Time, multiplied by (B) the Exchange Ratio (rounded down to the nearest whole share).

•

Each outstanding Senti option held immediately before the Effective Time will be converted into an option to purchase a number of shares of Class A Common Stock (rounded down to the nearest whole share) equal to (A) the number of shares of Senti common stock subject to such option as at the time immediately before the Effective Time, multiplied by (B) the Exchange Ratio, at an exercise price per share equal to the current exercise price per share for such option divided by the Exchange Ratio (rounded up to the nearest whole cent).

Following the Closing, the Sellers may also be eligible to receive Contingency Consideration of up to an aggregate of 2,000,000 shares of Class A Common Stock based on the share price of the Class A Common Stock following the Business Combination or, in certain circumstances, upon the occurrence of a change in control in respect of DYNS. See the section titled “

Proposal 1: The Business Combination Proposal — Structure of the Business Combination

.”

As of the Record Date, the Exchange Ratio was approximately . Based on this Exchange Ratio, the total number of shares of Class A Common Stock expected to be issued in connection at the Closing of the Business Combination is 24,000,000 shares, and these shares are expected to represent approximately 40% or 52% of the issued and outstanding shares of Class A Common Stock immediately following the closing of the PIPE Investment and the Business Combination, assuming no redemptions occur and maximum redemptions occur, respectively, and assuming that no shares of Class A Common Stock subject to Non-Redemption Agreements are redeemed. Please see the section entitled “

Unaudited Pro Forma

Condensed Combined Financial Information”

for further information regarding what constitutes a “maximum redemption” scenario.

The Board’s Reasons for Approval of the Business Combination

The Board considered a wide variety of factors in connection with its evaluation of the Business Combination. In light of the complexity of those factors, the Board, as a whole, did not consider it practicable to,

Table of Contents

nor did it attempt to, quantify or otherwise assign relative weights to the specific factors it took into account in reaching its decision. Individual members of the Board may have given different weight to different factors.

For a more complete description of the Board’s reasons for the approval of the Business Combination and its recommendations in favor of the Business Combination Proposal, please see the section entitled “

Proposal 1: The Business Combination — The Board’s Reasons for Approval of the Business Combination.

”

Accounting Treatment

Notwithstanding the legal form of the Business Combination pursuant to the Business Combination Agreement, the Business Combination will be accounted for as a reverse recapitalization in accordance with U.S. generally accepted accounting principles (“GAAP”). Under this method of accounting, DYNS will be treated as the acquired company for financial reporting purposes, whereas Senti will be treated as the accounting acquiror. In accordance with this accounting method, the Business Combination will be treated as the equivalent of Senti issuing stock for the net assets of DYNS, accompanied by a recapitalization. The net assets of DYNS will be stated at historical cost, with no goodwill or other intangible assets recorded, and operations prior to the Business Combination will be those of Senti. Senti has been determined to be the accounting acquiror for purposes of the Business Combination based on an evaluation of the following facts and circumstances:

•

Senti will control a majority of the governing body of New Senti;

•

Senti’s operations prior to the Business Combination will comprise the ongoing operations of New Senti; and

•

Senti’s existing senior management team will comprise the senior management team of the Combined Company.

Pro Forma Ownership of New Senti Upon Closing

Immediately after the Closing, assuming no Public Stockholder exercises its redemption rights, the Sellers will own approximately 39% of the shares of DYNS Common Stock to be outstanding immediately after the Business Combination, Public Stockholders will own approximately 41% of the shares of DYNS Common Stock, the Sponsor will own approximately 9% of the shares of DYNS Common Stock, the PIPE Investors will own approximately 11% of the shares of DYNS Common Stock and the Anchor Investors will own approximately % of the shares of DYNS Common Stock, in each case, based on the number of shares of Class A Common Stock and Class B Common Stock outstanding as of the Record Date. These pro forma ownership percentages also assume no exercise of any options to purchase Class A Common Stock that will be outstanding immediately following the Business Combination, whether such options are issued under the Incentive Plan or otherwise, and exclude the issuance of any shares in connection with the Incentive Plan and the ESPP following the Business Combination. If the actual facts are different from the assumptions stated above, then the levels of ownership interest set forth above will be different. For more information, please see the section entitled “

Unaudited Pro Forma Condensed Combined Financial Information

.”

In connection with the Initial Public Offering, the Sponsor and the directors, officers and advisors of DYNS entered into a

lock-up

30-trading

day period commencing at least 150 days after the initial business combination, or (ii) New Senti consummates a subsequent liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of its stockholders having the right to exchange their shares of Class A Common Stock for cash, securities or other property.

lock-up

described in the preceding sentence, the “Existing Sponsor

Lock-ups”).

In connection with DYNS’s entry into the Business Combination Agreement, pursuant to the Sponsor Support Agreement (a copy of which is exhibited to the Business Combination Agreement), and effective as of the consummation of the Closing, the Existing Sponsor

Special Meeting Information

Date, Time and Place of Special Meeting

The Special Meeting will be held virtually on 2022, at AM, Eastern Time, at

. DYNS stockholders may attend, vote and examine the list of DYNS stockholders entitled to vote at the Special Meeting by visiting and entering the control number found on their proxy card, voting instruction form or notice they previously received. In light of public health concerns regarding the coronavirus

(COVID-19),

the Special Meeting will be held in a virtual meeting format only. You will not be able to attend the Special Meeting physically.

Voting Power; Record Date

DYNS stockholders will be entitled to vote or direct votes to be cast at the Special Meeting if they owned DYNS Common Stock at the close of business on , 2022, which is the Record Date for the Special Meeting. Stockholders will have one vote for each share of DYNS Common Stock owned at the close of business on the Record Date. If your shares are held in “street name” or are in a margin or similar account, you should contact your broker to ensure that votes related to the shares you beneficially own are properly counted. On the Record Date, there were 29,465,500 shares of DYNS Common Stock entitled to vote at the Special Meeting, of which 6,465,500 were owned by the Sponsor or an affiliate thereof.

Quorum and Vote of DYNS Stockholders

Table of Contents

represented at the Special Meeting in order to constitute a quorum. Abstentions and withheld votes will count as present for the purposes of establishing a quorum, but will not count as votes cast at the Special Meeting for any of the Proposals. Because the Proposals are

“non-discretionary”

items, your broker will not be able to vote uninstructed shares for any of the Proposals. As a result, if you do not provide voting instructions, a broker

“non-vote”

will be deemed to have occurred for each of the Proposals. Broker

“non-votes”

will not be counted as present for purposes of determining whether a quorum is present. As of the Record Date, the Sponsor holds approximately 21.9% of the outstanding DYNS Common Stock.

The Proposals presented at the Special Meeting will require the following votes:

•

The approval of the Charter Amendment Proposal and each of the Charter Amendment Proposals will require the affirmative vote of a majority of the issued and outstanding shares of each of the Class A Common Stock and Class B Common Stock, voting separately as well as the vote of a majority of the issued and outstanding shares of Class A Common Stock and Class B Common Stock, voting together as a single class. Accordingly, a DYNS stockholder’s failure to vote by proxy or to vote in person (which would include presence at a virtual meeting) at the Special Meeting or an abstention will have the same effect as a vote “AGAINST” the Charter Amendment Proposal.

•

The approval of each of the Nasdaq Stock Issuance Proposal, the Incentive Plan Proposal, the ESPP Proposal and the Adjournment Proposal and each of the Advisory Charter Amendment Proposals will require the affirmative vote of the holders of a majority of the shares of DYNS Common Stock cast in respect of the relevant Proposal and entitled to vote thereon at the Special Meeting, voting as a single class.

•

The Director Election Proposal will require a plurality vote of the shares of DYNS Class B Common Stock cast in respect of that Proposal and entitled to vote thereon at the Special Meeting. “Plurality” means that the individuals who receive the largest number of votes cast “FOR” are elected as directors. Consequently, any shares not voted “FOR” a particular nominee (whether as a result of an abstention, a direction to withhold authority or a broker

non-vote)

will not be counted in the nominee’s favor.

Abstentions and broker

non-votes

will have no effect on any of the Proposals that will be presented at the Special Meeting.

Redemption Rights of DYNS Stockholders

Pursuant to the Current Charter, any holders of Public Shares may demand that such shares be redeemed in exchange for a pro rata share of the aggregate amount on deposit in the Trust Account, less franchise and income taxes payable. If demand is properly made and the Business Combination is consummated, these shares, immediately prior to the Business Combination, will cease to be outstanding and will represent only the right to receive a pro rata share of the aggregate amount then on deposit in the Trust Account (including interest earned on the funds held in the Trust Account and not previously released to pay the Company’s franchise and income taxes, less any owed but unpaid taxes on the funds in the Trust Account). For illustrative purposes, based on funds in the Trust Account of $

on the Record Date, the estimated per share redemption price would have been approximately $

Table of Contents

In order to exercise your redemption rights, you must:

•

check the box on the enclosed proxy card to elect redemption;

•

provide, in the written request to redeem your Public Shares for cash to Continental, DYNS’s transfer agent, a “Stockholder Certification” if you are not acting in concert or as a “group” (as defined in

Section 13d-3

of the Exchange Act) with any other stockholder with respect to shares of DYNS Common Stock; and

•

prior to , 2022 (two business days before the Special Meeting), tender your shares physically or electronically and submit a request in writing that DYNS redeem your Public Shares for cash to Continental at the following address:

Continental Stock Transfer & Trust Company

One State Street Plaza, 30

Floor

New York, New York 10004

Attn: Mark Zimkind

E-mail:

mzimkind@continentalstock.com; or

deliver your Public Shares either physically or electronically through DTC to Continental at least two business days before the Special Meeting. Public Stockholders seeking to exercise their redemption rights and opting to deliver physical certificates should allot sufficient time to obtain physical certificates from Continental and time to effect delivery. It is DYNS’s understanding that stockholders should generally allot at least two weeks to obtain physical certificates from Continental. However, DYNS does not have any control over this process and it may take longer than two weeks. Stockholders who hold their Public Shares in “street” name will have to coordinate with their bank, broker or other nominee to have the shares certificated or delivered electronically. If you do not submit a written request and deliver your Public Shares as described above, your shares will not be redeemed.

Any request for redemption, once made by a Public Stockholder, may be withdrawn at any time prior to the time the vote is taken with respect to the Business Combination Proposal at the Special Meeting. If you deliver your Public Shares for redemption directly to Continental or deliver your Public Shares either physically or electronically through DTC to Continental, and later decide prior to the Special Meeting not to elect redemption, you may request that Continental return the shares (physically or electronically). You may make such request by contacting Continental at (917)

262-2373,

by email at [proxy@continentalstock.com] or by writing to the address listed above.

Prior to exercising redemption rights, stockholders should verify the market price of shares of Class A Common Stock as they may receive higher proceeds from the sale of their shares of Class A Common Stock in the public market than from exercising their redemption rights if the market price per share is higher than the redemption price. We cannot assure you that you will be able to sell your shares of Class A Common Stock in the open market, even if the market price per share is higher than the redemption price stated above, as there may not be sufficient liquidity in Class A Common Stock when you wish to sell your shares.

If you exercise your redemption rights, your shares of Class A Common Stock will cease to be outstanding immediately prior to the Business Combination and will only represent the right to receive a pro rata share of the aggregate amount on deposit in the Trust Account, as described above. You will no longer own those shares and will have no right to participate in, or have any interest in, the future growth of the Combined Company, if any. You will be entitled to receive cash for these shares only if you properly and timely demand redemption, in accordance with the process described above.

If the Business Combination is not approved or completed for any reason, then Public Stockholders who elected to exercise their redemption rights will not be entitled to redeem their shares. In such case DYNS will promptly return any Public Shares previously delivered by the Public Stockholders.

Tax Consequences of Business Combination

For a description of the material U.S. federal income tax consequences of the Business Combination, please see the information set forth in the section entitled “

Material U.S. Federal Income Tax Considerations

.”

Appraisal Rights

DYNS’s stockholders do not have appraisal rights in connection with the Business Combination under Delaware law.

Regulatory Matters

Under the HSR Act and the rules that have been promulgated thereunder by the U.S. Federal Trade Commission (“FTC”), certain transactions may not be consummated unless information has been furnished to the Antitrust Division of the Department of Justice (“Antitrust Division”) and the FTC and certain waiting period requirements have been satisfied. The Business Combination is subject to these requirements and may not be completed until the expiration of a

30-day

waiting period following the filing of the required Notification and Report Forms with the Antitrust Division and the FTC or until early termination is granted. On January 10, 2022, DYNS and Senti filed their respective HSR Act Notification and Report Forms with the Antitrust Division and the FTC. Consequently, the required waiting period expired at 11:59 p.m. Eastern Time on February 9, 2022.

At any time before or after consummation of the Business Combination, notwithstanding expiration or termination of the waiting period under the HSR Act, the applicable competition authorities in the United States or any other applicable jurisdiction could take such action under applicable antitrust laws as such authority deems necessary or desirable in the public interest, including seeking to enjoin the consummation of the Business Combination, conditionally approving the Business Combination upon divestiture of certain of New Senti’s assets, subjecting the completion of the Business Combination to regulatory conditions or seeking other remedies. Private parties may also seek to take legal action under the antitrust laws under certain circumstances. DYNS cannot assure you that the Antitrust Division, the FTC, any state attorney general, or any other government authority will not attempt to challenge the Business Combination on antitrust grounds, and, if such a challenge is made, DYNS cannot assure you as to its result. Under the Business Combination Agreement, DYNS and Senti are not obligated to agree to sell, license or otherwise dispose of any entities, assets or facilities (or agree to do so), or terminate, assign or amend any existing relationships or contractual rights or obligations, or enter into new licenses or other contracts in order to obtain approval of the Business Combination by the FTC, the Antitrust Division or otherwise.

Neither DYNS nor Senti is aware of any material regulatory approvals or actions that are required for completion of the Business Combination other than the expiration of the waiting period under the HSR Act, which period has expired. It is presently contemplated that if any such additional regulatory approvals or actions are required, those approvals or actions will be sought. There can be no assurance, however, that any additional approvals or actions will be obtained.

Proxy Solicitation

Proxies may be solicited by mail, telephone or in person (which would include presence at a virtual meeting). DYNS has engaged to assist in the solicitation of proxies. If a stockholder grants a proxy, they may still vote their shares in person (which would include presence at a virtual meeting) if they revoke their proxy before the Special Meeting. A stockholder may also change their vote by submitting a later-dated proxy as described in the section entitled “

Special Meeting of DYNS Stockholders — Revoking Your Proxy

.”

Interests of the Sponsor and DYNS’s Directors and Officers in the Business Combination

In considering the recommendation of the Board to vote in favor of approval of the Business Combination Proposal, the Charter Amendment Proposal and the other Proposals, DYNS stockholders should keep in mind

Table of Contents

that the Sponsor (which is affiliated with certain of DYNS’s officers and directors) and DYNS’s officers and directors have interests in such Proposals that are different from, or in addition to, your interests as a DYNS stockholder. These interests include, among other things:

•

If the Business Combination with Senti or another business combination is not consummated by May 28, 2023 (or such later date as may be approved by DYNS’s stockholders), DYNS will cease all operations except for the purpose of winding up, redeeming 100% of the outstanding Public Shares for cash and, subject to the approval of its remaining stockholders and its Board, dissolving and liquidating. In such event, (i) the 5,750,000 Founder Shares held by the Sponsor, which were acquired by the Sponsor for a purchase price of approximately $0.004 per share, or $25,000 in the aggregate, prior to the Initial Public Offering, and (ii) the 715,500 shares of Class A Common Stock purchased by the Sponsor for a purchase price of $10.00 per share, or $7,155,000 in the aggregate, in the Concurrent Private Placement, would be worthless because the holders are not entitled to participate in any redemption or distribution from the Trust Account with respect to such securities. Such securities had an aggregate market value of approximately $ million based upon the closing price of $ per share of Class A Common Stock on Nasdaq on the Record Date.

•

The fact that given the differential in the purchase price that the Sponsor paid for the Founder Shares, as compared to the price of the Public Shares sold in the Initial Public Offering and the shares of Class A ordinary shares that the sponsor will receive upon conversion of the Founder Shares in connection with the Business Combination, the Sponsor may earn a positive rate of return on its investment even if the Class A Common Stock trades below the price initially paid for the Public Shares in the Initial Public Offering and the Public Stockholders experience a negative rate of return following the completion of the Business Combination;

•

If DYNS is unable to complete a business combination within the required time period, the Sponsor will be personally liable under certain circumstances described herein to ensure that the proceeds in the Trust Account are not reduced by the claims of target businesses or claims of vendors or other entities that are owed money by DYNS for services rendered or contracted for or products sold to DYNS. If DYNS consummates a business combination, on the other hand, DYNS will be liable for all such claims.

•

The Business Combination Agreement provides for the continued indemnification of DYNS’s current directors and officers and the continuation of directors’ and officers’ liability insurance covering DYNS’s current directors and officers from and after the Effective Time for a period of six (6) years.

•

the fact that of DYNS’s current directors and officers, are expected to be directors of New Senti after the consummation of the Business Combination and as such, in the future, they may receive cash fees, stock options, stock awards or other remuneration that the New Senti Board determines to pay to them and any other applicable compensation as described under section “Executive Compensation - Director Compensation”;

•

None of DYNS’s officers or directors will be required to commit his or her full time to the affairs of New Senti and, accordingly, may have conflicts of interest in allocating his or her time among various business activities.

•

In the course of their other business activities, DYNS’s officers and directors may become aware of investment and business opportunities which may be appropriate for presentation to New Senti as well as the other entities with which they are affiliated. DYNS’s management may have conflicts of interest in determining to which entity a particular business opportunity should be presented.

•

The Sponsor and DYNS’s other initial stockholders have agreed to waive their redemption rights with respect to any shares of DYNS Common Stock they may hold in connection with the Business Combination. Additionally, our initial stockholders have agreed to waive their redemption rights with respect to any Founder Shares and Public Shares held by them if we fail to consummate our initial business combination within 24 months after the closing of the Initial Public Offering. If DYNS does

not complete an initial business combination within such applicable time period, the proceeds of the sale of the Private Placement Shares held in the Trust Account will be used to fund the redemption of the Public Shares, and the Private Placement Shares purchased in the Concurrent Private Placement will expire worthless. The Private Placement Shares purchased in the Concurrent Private Placement held by DYNS’s initial stockholders had an aggregate market value of approximately $ million based upon the closing price of $ per DYNS share on Nasdaq on the Record Date. In addition, effective as of the consummation of the Closing, with certain limited exceptions, the

lock-up

arrangements described in the Investor Rights Agreement (a copy of the form of which is exhibited to the Business Combination Agreement) will prevent the transfer or assignment of Class A Common Stock (or any securities convertible into or exercisable or exchangeable for shares of Class A Common Stock) in accordance with the terms thereof. These

lock-up

arrangements are further described in the section entitled “

Proposal 1: The Business Combination Agreement

–

Related Agreements

–

Investor Rights Agreement

.” Since the Sponsor and DYNS’s officers and directors may directly or indirectly own DYNS Common Stock following the Initial Public Offering, DYNS’s officers and directors may have a conflict of interest in determining whether a particular target business is an appropriate business with which to effectuate the initial business combination.

•

DYNS’s officers and directors may have a conflict of interest with respect to evaluating a particular business combination if the retention or resignation of any such officers and directors was included by a target business as a condition to any agreement with respect to the initial business combination.

•

The Sponsor and DYNS’s officers or directors may have a conflict of interest with respect to evaluating a business combination and financing arrangements as DYNS may obtain loans from the Sponsor or an affiliate of the Sponsor or any of DYNS’s officers or directors to finance transaction costs in connection with an intended initial business combination. As of , 2022, no such loans are outstanding.

•

The Sponsor, certain stockholders of DYNS, and certain stockholders of Senti will be party to the Investor Rights Agreement, which will come into effect at the Effective Time. See the section entitled “

Proposal 1: The Business Combination Agreement

– Investor Rights Agreement”

for a discussion of the terms of this agreement.

Summary of Risk Factors

The following is a summary of the principal risks to which (i) Senti’s business, operations and financial performance and (ii) the Business Combination are subject. Each of these risks is more fully described in the individual risk factors set forth under “

Risk Factors

” in this proxy statement/prospectus. Unless the context otherwise requires, all references in this subsection to the “Company,” “we,” “us” or “our” refer to the business of Senti prior to the consummation of the Business Combination, which will be the business of the Combined Company following the consummation of the Business Combination.

Table of Contents

Risks Related to the Business, Operations and Financial Performance of Senti

•

We are a preclinical stage biotechnology company with a history of losses. We expect to continue to incur significant losses for the foreseeable future and may never achieve or maintain profitability.

•

We will need substantial additional funds to advance development of product candidates and our gene circuit platform, and we cannot guarantee that we will have sufficient funds available in the future to develop and commercialize our current or potential future product candidates and technologies.

•

We have identified a material weakness in our internal control over financial reporting. If our remediation of the material weakness is not effective, or if we experience additional material weaknesses or otherwise fail to maintain an effective system of internal controls in the future, we may not be able to accurately report our financial condition or results of operations, which may adversely affect investor confidence in us and, as a result, the value of our common stock.

•

Our history of recurring losses and anticipated expenditures raises substantial doubt about our ability to continue as a going concern. Our ability to continue as a going concern requires that we obtain sufficient funding to finance our operations.

•

If any of our current or potential future product candidates is ever tested in humans, it may not demonstrate the safety, purity and potency, or efficacy, necessary to become approvable or commercially viable.

•

Our gene circuit platform technologies are based on novel technologies that are unproven and may not result in approvable or marketable products, which exposes us to unforeseen risks and makes it difficult for us to predict the time and cost of product development and potential for regulatory approval.

•

Although we intend to explore other therapeutic opportunities in addition to the product candidates we are currently pursuing, we may fail to identify viable new product candidates for clinical development, which could materially harm our business.

•

Clinical development includes a lengthy and expensive process with an uncertain outcome, and results of earlier studies and trials may not be predictive of future trial results.

•

We rely on third parties to conduct our preclinical studies, and plan to rely on third parties to conduct clinical trials, and those third parties may not perform satisfactorily. If third parties on which we intend to rely to conduct certain preclinical and clinical studies do not perform as contractually required, fail to satisfy regulatory or legal requirements or miss expected deadlines, our development program could be delayed or unsuccessful, and we may not be able to obtain regulatory approval for or commercialize our product candidates when expected, or at all.

•

We may not be able to maintain our existing strategic partnerships and collaboration arrangements or enter into new strategic partnerships and collaborations for the development, manufacture and commercialization of product candidates based on our platform technology on terms that are acceptable to us, or at all.

•

The manufacturing of our product candidates is complex. We may encounter difficulties in production. If we encounter any such difficulties, our ability to supply our product candidates for clinical trials or, if approved, for commercial sale, could be delayed or halted entirely.

•

We face competition from companies that have developed or may develop product candidates for the treatment of the diseases that we may target, including companies developing novel therapies and platform technologies. If these companies develop platform technologies or product candidates more rapidly than we do, or if their platform technologies or product candidates are more effective or have fewer side effects, our ability to develop and successfully commercialize product candidates may be adversely affected.

Table of Contents

•

Our future success depends on our ability to retain key employees, directors, consultants and advisors and to attract, retain and motivate qualified personnel.

•

We may experience difficulties in managing our growth and expanding our operations. We have limited experience in therapeutic development. As our current and potential future product candidates enter and advance through preclinical studies and any clinical trials, we will need to expand our development, regulatory and manufacturing capabilities or contract with other organizations to provide these capabilities for us.

•

Our business, operations and clinical development plans and timelines could be adversely affected by the ongoing COVID-19 pandemic, including business interruptions, staffing shortages and supply chain issues arising from the pandemic on the manufacturing, clinical trial and other business activities performed by us or by third parties with whom we may conduct business, including our anticipated contract manufacturers, contract research organizations (CROs), suppliers, shippers and others.

•

If we are unable to obtain or protect intellectual property rights related to our technology and current or future product candidates, or if our intellectual property rights are inadequate, our competitors could develop and commercialize products and technology similar or identical to ours, and we may not be able to compete effectively in our market or successfully commercialize any product candidates we may develop.

•

We may be unable to obtain U.S. or foreign regulatory approval and, as a result, be unable to commercialize our current or potential future product candidates.

•

Even if we are able to commercialize any product candidate, such product candidate may become subject to unfavorable pricing regulations or third-party coverage and reimbursement policies, which would harm our business.

•

We or the third parties upon whom we depend may be adversely affected by natural disasters, including earthquake, flood, fire, explosion, extreme weather conditions, or medical epidemics.

Risks Related to the Business Combination and Redemptions

•

DYNS will not have any right after the Closing to make damage claims against Senti or Senti’s stockholders for the breach of any representation, warranty or covenant made by Senti in the Business Combination Agreement.

•

Subsequent to the Closing, New Senti may be required to take write-downs or write-offs, restructuring and impairment or other charges that could have a significant negative effect on its financial condition, results of operations and stock price, which could cause you to lose some or all of your investment.

•

The Sponsor and DYNS’s officers and directors own DYNS Common Stock that will be worthless and have incurred reimbursable expenses that may not be reimbursed or repaid if the Business Combination is not approved. Such interests may have influenced their decision to approve and, in the case of the Board, recommend, the Business Combination with Senti.

•

The exercise of DYNS’s directors’ and officers’ discretion in agreeing to changes or waivers in the terms of the Business Combination Agreement may result in a conflict of interest when determining whether such changes to the terms of the Business Combination or waivers of conditions are appropriate and in the best interests of DYNS’s stockholders.

•

Table of Contents

liquidating. In such event, third parties may bring claims against DYNS and, as a result, the proceeds held in the Trust Account could be reduced and the per-share liquidation price received by stockholders could be less than $10.00 per Public Share.

•

Neither the Board nor any committee thereof obtained a third-party financial opinion in determining whether or not to pursue the Business Combination.

•

There is no guarantee that a Public Stockholder’s decision to continue to hold shares of Class A Common Stock following the Business Combination will put the stockholder in a better future economic position than if they decided to redeem their Public Shares for a pro rata portion of the Trust Account, and vice versa.

•

The consummation of the Business Combination is conditioned on, among other things, there being at least $150,000,000 in cash available at Closing. DYNS has entered into Non-Redemption Agreements with the Anchor Investors to assist with satisfying this condition, however, the Anchor Investors’ commitments not to redeem or to transfer their shares of Class A Common Stock do not apply in circumstances where they are compelled to do so in connection with non-discretionary ETF or mutual fund pro rata rebalancing transfers. If one or more Anchor Investors was compelled to transfer shares of Class A Common Stock for this reason, it is possible that there would not be $150,000,000 in cash available at Closing. As this condition is for Senti’s benefit, it is possible that Senti could waive it prior to Closing, although there is no guarantee that it would. If Senti did waive the condition in these circumstances, it is possible that New Senti would have insufficient capital to conduct and grow its business after Closing in the manner described in this proxy statement/prospectus.

Comparison of Governance and Stockholders’ Rights

Following the Closing, the rights of DYNS stockholders who remain New Senti stockholders will no longer be governed by the Current Charter and DYNS’s duly adopted bylaws and will instead be governed by the Proposed Charter and the new bylaws (as amended from time to time) adopted in connection with the Charter Amendment Proposal. See “

Comparison of Governance and Stockholders’ Rights

” beginning on page 331.

SELECTED UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following selected unaudited pro forma condensed combined financial data is derived from the unaudited pro forma condensed combined balance sheet and unaudited pro forma condensed combined statements of operations included elsewhere in this proxy statement/prospectus and is provided to aid you in your analysis of the financial aspects of the Business Combination, Non-Redemption Agreement and the consummation of the PIPE Investment, which are collectively referred to as the “Transactions.”

The unaudited pro forma condensed combined financial statements are based on the DYNS historical financial statements and the Senti historical consolidated financial statements as adjusted to give effect to the Transactions. The unaudited pro forma condensed combined balance sheet gives pro forma effect to the Transactions as if they had been consummated on September 30, 2021. The unaudited pro forma condensed combined statements of operations for the nine months ended September 30, 2021 and the year ended December 31, 2020 give effect to the Transactions as if they had occurred on January 1, 2020, which is the beginning of the earliest period presented. The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2020 does not reflect the DYNS historical financial statements since DYNS was only incorporated on March 1, 2021.

The unaudited pro forma condensed combined financial statements were prepared in accordance with Article 11 of SEC Regulation S-X, as amended by the final rule, Release No. 33-10786,

Amendments to Financial Disclosures

about Acquired

and Disposed

Businesse

. Release No. 33-10786 replaced the previous pro forma adjustment criteria with simplified requirements to depict the accounting for the Transactions (“Transaction Accounting Adjustments”) and present the reasonably estimable synergies and other transaction effects that have occurred or are reasonably expected to occur (“Management’s Adjustments”). Management has elected not to present Management’s Adjustments and will only be presenting Transaction Accounting Adjustments in the unaudited pro forma condensed combined financial information. The adjustments presented in the unaudited pro forma condensed combined financial statements have been identified and presented to provide relevant information necessary for an understanding of the Combined Company reflecting the Transactions.

The unaudited pro forma condensed combined financial statements are provided for illustrative purposes only and are not necessarily indicative of what the actual results of operations and financial position would have been had the Transactions taken place on the dates indicated, nor are they indicative of the future consolidated results of operations or financial position of the Combined Company.

The unaudited pro forma condensed combined financial statements have been derived from and should be read in conjunction with:

•

the accompanying notes to the unaudited pro forma condensed combined financial statements included elsewhere in this proxy statement/prospectus;

•

the historical unaudited condensed financial statements of DYNS as of September 30, 2021 and for the period from March 1, 2021 (inception) through September 30, 2021 and the related notes included elsewhere in this proxy statement/prospectus;

Table of Contents

The selected unaudited pro forma condensed combined financial data below presents two redemption scenarios as follows:

•

Assuming No Redemptions (Scenario 1)

: This presentation assumes that no Public Stockholders exercise their right to redeem their Public Shares for their pro rata share of the trust account and thus the full amount held in the Trust Account as of the Closing is available for the Business Combination; and

•

Assuming Maximum Redemptions (Scenario 2)

: This presentation assumes that 14,308,345 Public Shares are redeemed resulting in an aggregate cash payment of approximately $143.1 million out of the Trust Account based on an assumed redemption price of $10.00 per share. This redemption figure is derived by substracting the 8,691,655 shares that will not be redeemed by Anchor Investors (due to Non-Redemption Agreements) from the 23,000,000 Public Shares issued and outstanding as at the Record Date. After a redemption of approximately $143.1 million out of the $230.0 million Trust Account, and the $66.8 million PIPE Investment, the available cash at Closing would be approximately $153.7 million, which would satisfy the condition in the Business Combination Agreement that there be at least$150.0 million in available Closing cash. When considering this maximum redemptions scenario, you should consider that the Anchor Investors’ commitments under the Non-Redemption Agreements not to redeem or to transfer their shares of Class A Common Stock do not apply in circumstances where they are compelled to do so in connection with non-discretionary ETF or mutual fund pro rata rebalancing transfers. If one or more Anchor Investors was compelled to transfer shares of Class A Common Stock for this reason, it is possible that more than 14,308,345 Public Shares could be redeemed and that there may not be $150,000,000 in cash available at Closing. As this condition is for Senti’s benefit, it is possible that Senti could waive it prior to Closing, although there is no guarantee that it would. The redemption of more than 14,308,345 Public Shares would change some of the figures presented in the maximum redemptions scenario in the unaudited pro forma financial data.

FORWARD-LOOKING STATEMENTS

This proxy statement/prospectus contains statements that are forward-looking and as such are not historical facts. This includes, without limitation, statements regarding the financial position, business strategy and the plans and objectives of management for future operations, including as they relate to the potential Business Combination. These statements constitute projections, forecasts and forward-looking statements, and are not guarantees of performance. Such statements can be identified by the fact that they do not relate strictly to historical or current facts.

Summary of Risk Factors

The following is a summary of principal risk to which (i) our business, operations and financial performance and (ii) the Business Combination and redemptions are subject. Each of these risks is more fully described in the individual risk factors immediately following this summary:

Risks Related to the Business, Operations and Financial Performance of Senti

•

We will need substantial additional funds to advance development of our product candidates and our gene circuit platform, and we cannot guarantee that we will have sufficient funds available in the future to develop and commercialize our current or potential future product candidates and technologies.

•

Our current product candidates are in preclinical development and have never been tested in humans. One or all of our current product candidates may fail in clinical development or suffer delays that materially and adversely affect their commercial viability.

•

Clinical development includes a lengthy and expensive process with an uncertain outcome, and results of earlier studies and trials may not be predictive of future trial results.

Table of Contents

•

Our future success depends on our ability to retain key employees, directors, consultants and advisors and to attract, retain and motivate qualified personnel.

•

Our business, operations and clinical development plans and timelines could be adversely affected by the ongoing

COVID-19 pandemic,

including business interruptions, staffing shortages and supply chain issues arising from the pandemic, on the manufacturing, clinical trial and other business activities performed by us or by third parties with whom we may conduct business, including our anticipated contract manufacturers, contract research organizations (CROs), suppliers, shippers and others.

•

We may be unable to obtain U.S. or foreign regulatory approval and, as a result, be unable to commercialize our current or potential future product candidates.

•

We or the third parties upon whom we depend may be adversely affected by other natural disasters, including earthquake, flood, fire, explosion, extreme weather conditions, or medical epidemics.

Risks Related to the Business Combination and Redemptions

•

Table of Contents

•

The exercise of DYNS’s directors’ and officers’ discretion in agreeing to changes or waivers in the terms of the Business Combination Agreement may result in a conflict of interest when determining whether such changes to the terms of the Business Combination Agreement or waivers of conditions are appropriate and in the best interests of DYNS’s stockholders.

•

If DYNS is unable to complete the Business Combination with Senti or another business combination by May 28, 2023 (or such later date as may be approved by DYNS’s stockholders), DYNS will cease all operations except for the purpose of winding up, redeeming 100% of the outstanding Public Shares for cash and, subject to the approval of its remaining stockholders and its Board, dissolving and liquidating. In such event, third parties may bring claims against DYNS and, as a result, the proceeds held in the Trust Account could be reduced and the

per-share

liquidation price received by stockholders could be less than $10.00 per Public Share.

•

Neither the Board nor any committee thereof obtained a third-party financial opinion in determining whether or not to pursue the Business Combination.

•

There is no guarantee that a Public Stockholder’s decision whether to continue to hold shares of Class A Common Stock following the Business Combination will put the stockholder in a better future economic position than if they decided to redeem their Public Shares for a pro rata portion of the Trust Account, and vice versa.

Risks Related to Senti’s Limited Operating History and Financial Condition

We are a preclinical stage biotechnology company with a history of losses. Since our inception, we have devoted substantially all of our resources to research and development, preclinical studies, building our management team and building our intellectual property portfolio, and we have incurred significant operating losses. Our net losses were $21.2 million and $19.9 million for the years ended December 31, 2019 and 2020, respectively. Our net loss was $44.4 million as of September 30, 2021. As of September 30, 2021, we had an accumulated deficit of $104.2 million. Substantially all of our losses have resulted from expenses incurred in connection with our research and development programs and from general and administrative costs associated with our operations. To date, we have not generated any revenue from product sales, and we have not sought or obtained regulatory approval for any product candidate. Furthermore, we do not expect to generate any revenue from product sales for the foreseeable future, and we expect to continue to incur significant operating losses for the foreseeable future due to the cost of research and development, preclinical studies, clinical trials, manufacturing and the regulatory approval process for our current and potential future product candidates.

Table of Contents

We expect our net losses to increase substantially as we:

•

continue to advance our gene circuit platform technologies;

•

continue preclinical development of our current and future product candidates and initiate additional preclinical studies;

•

commence clinical trials of our current and future product candidates;

•

establish our manufacturing capability, including developing our contract development and manufacturing organization relationships and building our internal manufacturing facilities;

•

acquire and license technologies aligned with our gene circuit platform technologies;

•

seek regulatory approval of our current and future product candidates;

•

expand our operational, financial, and management systems and increase personnel, including personnel to support our preclinical and clinical development, manufacturing and commercialization efforts;

•

continue to develop, perfect, and defend our intellectual property portfolio; and

•

incur additional legal, accounting, or other expenses in operating our business, including the additional costs associated with operating as a public company.

However, the amount of our future losses is uncertain. Our ability to achieve or sustain profitability, if ever, will depend on, among other things, successfully developing product candidates, obtaining regulatory approvals to market and commercialize product candidates, manufacturing any approved products on commercially reasonable terms, entering into potential future alliances, establishing a sales and marketing organization or suitable third-party alternatives for any approved product and raising sufficient funds to finance business activities. If we, or our potential future collaborators, are unable to commercialize one or more of our product candidates, or if sales revenue from any product candidate that receives approval is insufficient, we will not achieve or sustain profitability, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

Even if we consummate the Business Combination, we will need substantial additional funds to advance development of product candidates and our gene circuit platform, and we cannot guarantee that we will have sufficient funds available in the future to develop and commercialize our current or potential future product candidates and technologies.

The development of biotechnology product candidates is capital-intensive. If any of our current or potential future product candidates enter and advance through preclinical studies and clinical trials, we will need substantial additional funds to expand our development, regulatory, manufacturing, marketing and sales capabilities. We have used substantial funds to develop our gene circuit platform,

SENTI-202,

SENTI-301,

SENTI-401

and other product candidates, and we will require significant funds to continue to develop our platform and conduct further research and development, including preclinical studies and clinical trials. In addition, upon the closing of the Business Combination, we expect to incur significant additional costs associated with operating as a public company.

As of September 30, 2021, we had $73.7 million in cash and cash equivalents. Our future capital requirements and the period for which we expect our existing resources to support our operations may vary significantly from what we expect. Our monthly spending levels vary based on new and ongoing research and development and other corporate activities. Because the length of time and activities associated with successful research and development of platform technologies and product candidates is highly uncertain, we are unable to estimate the actual funds we will require for development and any approved marketing and commercialization activities. The timing and amount of our operating expenditures will depend largely on:

•

the timing and progress of preclinical and clinical development of our current and potential future product candidates;

Table of Contents

•

the timing and progress of our development of our gene circuit platforms;

•

the number and scope of preclinical and clinical programs we decide to pursue;

•

the costs of building and operating our own dedicated Current Good Manufacturing Practice, or cGMP, and Current Good Tissue Practice, or cGTP facility to support clinical and commercial-scale production of multiple allogeneic NK cell product candidates, and the terms of any third-party manufacturing contract or biomanufacturing partnership we may enter into;

•

our ability to maintain our current licenses and collaborations, conduct our research and development programs and establish new strategic partnerships and collaborations;

•

the progress of the development efforts of our existing strategic partners and third parties with whom we may in the future enter into collaboration and research and development agreements;

•

the costs involved in obtaining, maintaining, enforcing and defending patents and other intellectual property rights;

•

the impact of the

COVID-19

pandemic on our business;

•

the cost and timing of regulatory approvals; and

•

our efforts to enhance operational systems and hire additional personnel, including personnel to support development of our product candidates and satisfy our obligations as a public company.

To date, we have primarily financed our operations through the sale of equity securities. We may seek to raise any necessary additional capital through a combination of public or private equity offerings, debt financings, collaborations, strategic alliances, licensing arrangements, grants and other marketing and distribution arrangements. We cannot assure you that we will be successful in acquiring additional funding at levels sufficient to fund our operations or on terms favorable to us. If we are unable to obtain adequate financing when needed, we may have to delay, reduce the scope of or suspend one or more of our preclinical studies, clinical trials, research and development programs or commercialization efforts. Because of the numerous risks and uncertainties associated with the development and commercialization of our current and potential future product candidates and the extent to which we may enter into collaborations with third parties to participate in their development and commercialization, we are unable to estimate the amounts of increased capital outlays and operating expenditures associated with our current and anticipated preclinical studies and clinical trials, including related manufacturing costs. To the extent that we raise additional capital through collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our current and potential future product candidates, future revenue streams or research programs or to grant licenses on terms that may not be favorable to us. If we do raise additional capital through public or private equity or convertible debt offerings, the ownership interest of our existing stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect our stockholders’ rights. If we raise additional capital through debt financing, we may be subject to covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends.

We do not expect to realize revenue from product sales or royalties from licensed products for the foreseeable future, if at all, and unless and until our current and potential future product candidates are clinically tested, approved for commercialization and successfully marketed.

We have identified a material weakness in our internal control over financial reporting. If our remediation of the material weakness is not effective, or if we experience additional material weaknesses in the future or otherwise fail to maintain an effective system of internal controls in the future, we may not be able to accurately report our financial condition or results of operations, which may adversely affect investor confidence in us and, as a result, the value of our common stock.

Prior to the closing of the Business Combination, we have been a private company with limited accounting personnel and other resources with which to address our internal control over financial reporting. In connection with our preparation and the audit of our consolidated financial statements as of and for the year ended

Table of Contents

December 31, 2020, we and our independent registered public accounting firm identified a material weakness as defined under the Securities Exchange Act of 1934, as amended, or the Exchange Act, and by the Public Company Accounting Oversight Board (United States) in our internal control over financial reporting. The material weakness related to a lack of sufficient and adequate resources in the finance and accounting function that resulted in a lack of formalized risk assessment process, lack of segregation of duties, and ineffective process level control activities over the management review of journal entries, account reconciliations and

non-routine

transactions. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our consolidated financial statements will not be prevented or detected on a timely basis.

We are in the process of implementing a risk assessment process and measures designed to improve our internal control over financial reporting and remediate the control deficiencies that led to the material weakness, including hiring additional accounting personnel. The process of designing and implementing effective internal controls is a continuous effort that requires us to anticipate and react to changes in our business and the economic and regulatory environments and to expend significant resources to maintain a system of internal controls that is adequate to satisfy our reporting obligations as a public company. For example, to maintain and improve the effectiveness of our financial reporting, we will need to commit significant resources, implement and strengthen existing disclosure processes, train personnel and provide additional management oversight.

We cannot be certain that the measures we have taken to date, and actions we may take in the future, will be sufficient to remediate the control deficiencies that led to our material weakness in our internal control over financial reporting or that they will prevent or avoid potential future material weaknesses. In addition, neither our management nor an independent registered public accounting firm has performed an evaluation of our internal control over financial reporting because no such evaluation has been previously required. The rules governing the standards that must be met for our management to assess our internal control over financial reporting are complex and require significant documentation, testing and remediation. Testing internal controls may divert our management’s attention from other matters that are important to our business.

Pursuant to Section 404 of the Sarbanes-Oxley Act, or Section 404, our management will be required to report upon the effectiveness of our internal control over financial reporting beginning with the annual report for our fiscal year ending December 31, 2022. Even if our management concludes that our internal control over financial reporting is effective, our independent registered public accounting firm may issue a report that is qualified if it is not satisfied with our controls or the level at which our controls are documented, designed, operated or reviewed. The rules governing the standards that must be met for management to assess our internal control over financial reporting are complex and require significant documentation, testing, and possible remediation. To comply with the requirements of being a reporting company under the Exchange Act, we will need to implement additional financial and management controls, reporting systems, procedures, and hire additional accounting and finance staff.

When we lose our status as an “emerging growth company” and become an “accelerated filer” or a “large accelerated filer,” our independent registered public accounting firm will be required to attest to the effectiveness of our internal control over financial reporting pursuant to Section 404. Accordingly, you may not be able to depend on any attestation concerning our internal control over financial reporting from our independent registered public accountants for the foreseeable future.

Our testing, or the subsequent testing by our independent registered public accounting firm, may reveal deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses. A material weakness in internal controls could result in our failure to detect a material misstatement of our annual or quarterly consolidated financial statements or disclosures. We may not be able to conclude on an ongoing basis that we have effective internal controls over financial reporting in accordance with Section 404. If we are unable to conclude that we have effective internal controls over financial reporting, investors could lose confidence in our reported financial information, which could have a material adverse effect on the trading price of our common stock.

We cannot be certain as to the timing of completion of our evaluation, testing and any remediation actions or the impact of the same on our operations. If we are unable to successfully remediate our existing or any future material weaknesses in our internal control over financial reporting, or identify any additional material

Table of Contents

weaknesses, the accuracy and timing of our financial reporting may be negatively impacted, we may be unable to maintain compliance with securities law requirements regarding timely filing of periodic reports in addition to applicable stock exchange listing requirements, investors may lose confidence in our financial reporting and our stock price may decline as a result. If we are not able to implement the requirements of Section 404 in a timely manner or with adequate compliance, our independent registered public accounting firm may issue an adverse opinion due to ineffective internal controls over financial reporting, and we may be subject to sanctions or investigation by regulatory authorities, such as the SEC. As a result, there could be a negative reaction in the financial markets due to a loss of confidence in the reliability of our consolidated financial statements. In addition, we may be required to incur costs in improving our internal control system and the hiring of additional personnel. Any such action could negatively affect our results of operations and cash flows.

Members of our management team have limited experience in managing the

day-to-day

operations of a public company and, as a result, we may incur additional expenses associated with the management of our company.

Members of our management team have limited experience in managing the

day-to-day

operations of a public company. As a result, we may need to obtain outside assistance from legal, accounting, investor relations, or other professionals that could be more costly than planned. We also plan to hire additional personnel to comply with additional SEC reporting requirements. These compliance costs will make some activities significantly more time-consuming and costly. If we lack cash resources to cover these costs in the future, our failure to comply with reporting requirements and other provisions of securities laws could negatively affect our stock price and adversely affect our potential results of operations, cash flow and financial condition after we commence operations.

We have incurred significant operating losses to date, and it is possible we may never generate a profit. Our consolidated financial statements included elsewhere in this proxy statement/prospectus have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. These consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of these uncertainties related to our ability to operate on a going concern basis.

We have concluded that our recurring losses from operations and need for additional financing to fund future operations raise substantial doubt about our ability to continue as a going concern. Similarly, our independent registered public accounting firm included an explanatory paragraph in its report on our consolidated financial statements as of and for the year ended December 31, 2020 with respect to this uncertainty. We believe that the $64.7 million of gross proceeds raised in May 2021 from the sale of our Series B redeemable convertible preferred stock, coupled with successful completion of the Business Combination, will eliminate this doubt and enable us to continue as a going concern; however, we may need to obtain alternative financing or significantly modify our operational plans for us to continue as a going concern. Based upon our current operating plan and assumptions, we believe that our existing cash and cash equivalents, including the results of the Business Combination, will be sufficient to fund our operations for at least the next 12 months. This estimate is based on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we expect. Changes may occur beyond our control that would cause us to consume our available capital before that time, including changes in and progress of our development activities and changes in regulation. Our future capital requirements will depend on many factors, including:

•

the scope, rate of progress, results and costs of platform development activities, preclinical studies, laboratory testing and clinical trials for our product candidates;

Table of Contents

•

the number and development requirements of product candidates that we may pursue, and other indications for our current product candidates that we may pursue;

•

the costs, timing and outcome of regulatory review of our product candidates;

•

the scope and costs of constructing and operating our planned cGMP and cGTP facility and any commercial manufacturing activities;

•

the cost associated with commercializing any approved product candidates;

•

the cost and timing of developing our ability to establish sales and marketing capabilities, if any;

•

the cost and timing of maintaining and expanding the applications of our gene circuit platform technology;

•

the costs of preparing, filing and prosecuting patent applications, maintaining, enforcing and protecting our intellectual property rights, defending intellectual property-related claims and obtaining licenses to third-party intellectual property;

•

the timing and amount of any milestone and royalty payments we are required to make under our present or future license agreements;

•

our ability to establish and maintain strategic partnerships and collaborations, including any biomanufacturing partnerships or collaborations involving the use of our platform technology, on favorable terms, if at all; and

•

the extent to which we acquire or

in-license

other product candidates and technologies and associated intellectual property.

We will require additional capital to complete our planned clinical development programs for our current product candidates to obtain regulatory approval. Any additional capital raising efforts may divert our management from their

day-to-day

activities, which may adversely affect our ability to develop and commercialize our current and future product candidates, if approved.

In addition, we cannot guarantee that future financing will be available on a timely basis, in sufficient amounts or on terms acceptable to us, if at all. Moreover, the terms of any financing may adversely affect the holdings or the rights of our stockholders and the issuance of additional securities by us, whether equity or debt, or the market perception that such issuances are likely to occur, could cause the market price of our common stock to decline. If we are unable to raise sufficient capital when needed, our business, financial condition and results of operations will be harmed, and we will need to significantly modify our operational plans to continue as a going concern. If we are unable to continue as a going concern, we might have to liquidate our assets and the values we receive for our assets in liquidation or dissolution could be significantly lower than the values reflected in our consolidated financial statements.

Our ability to use net operating loss carryforwards, or NOLs, and credits to offset future taxable income may be subject to certain limitations.

Our net operating loss carryforwards, or NOLs, could expire unused and be unavailable to offset future income tax liabilities because of their limited duration or because of restrictions under U.S. tax law. NOLs generated in taxable years beginning before January 1, 2018 are permitted to be carried forward for 20 taxable years under applicable U.S. federal income tax law. Under the Tax Cuts and Jobs Act of 2017, or the Tax Act, as modified by the Coronavirus Aid, Relief and Economic Security Act, or the CARES Act, NOLs arising in tax years beginning after December 31, 2020 may not be carried back. Moreover, under the Tax Act as modified by the CARES Act, NOLs generated in taxable years beginning after December 31, 2017 may be carried forward indefinitely, but the deductibility of such NOLs generally will be limited in taxable years beginning after December 31, 2020 to 80% of current year taxable income. As of December 31, 2020, we had NOLs for federal

Table of Contents

and state income tax purposes of approximately $109.9 million, a portion of which expire beginning in 2036 if not utilized. NOLs generated in 2020 for federal tax reporting purposes of approximately $23.7 million have an indefinite life.

In general, under Section 382 of the Internal Revenue Code of 1986, as amended, or the Code, a corporation that undergoes an “ownership change” (defined under Section 382 of the Code and applicable Treasury Regulations as a greater than 50 percentage point change (by value) in a corporation’s equity ownership by certain stockholders over a rolling three-year period) is subject to limitations on its ability to utilize its

pre-change

NOLs to offset future taxable income. We have not determined whether our NOLs are limited under Section 382 of the Code. We may have experienced ownership changes in the past and may experience ownership changes in the future, including as a result of the Business Combination or subsequent shifts in our stock ownership (some of which are outside our control). Furthermore, our ability to utilize NOLs of companies that we may acquire in the future may be subject to limitations. There is also a risk that due to regulatory changes, such as suspensions on the use of NOLs or other unforeseen reasons, our existing NOLs could expire or otherwise be unavailable to reduce future income tax liabilities, including for state tax purposes. For these reasons, we may not be able to utilize a material portion of the NOLs reflected on our balance sheet, even if we attain profitability, which could potentially result in increased future tax liability to us and could adversely affect our operating results and financial condition.

Risks Related to the Development and Clinical Testing of Our Product Candidates

We have no products on the market or that have gained regulatory approval or that have entered clinical trials. None of our product candidates has ever been tested in humans. Our ability to achieve and sustain profitability depends on obtaining regulatory approvals for and successfully commercializing product candidates, either alone or with collaborators.

Before obtaining regulatory approval for the commercial distribution of our product candidates, we or a collaborator must conduct extensive preclinical studies, followed by clinical trials to demonstrate the safety, purity and potency, or efficacy of our product candidates in humans. There is no guarantee that the U.S. Food and Drug Administration, or the FDA, will permit us to conduct clinical trials. Further, we cannot be certain of the timely completion or outcome of our preclinical studies and cannot predict if the FDA or other regulatory authorities will accept our proposed clinical programs, our clinical protocols or if the outcome of our preclinical studies will ultimately support the further development of our preclinical programs or testing in humans. As a result, we cannot be sure that we will be able to submit Investigational New Drugs, or INDs, or similar applications for our proposed clinical programs on the timelines we expect, if at all, and we cannot be sure that submission of INDs or similar applications will result in the FDA or other regulatory authorities allowing clinical trials for any of our product candidates to begin.

Our current product candidates are in preclinical development and we are subject to the risks of failure inherent in the development of product candidates based on novel approaches, targets and mechanisms of action. Although we anticipate initiating clinical trials for our lead product candidates, there is no guarantee that we will be able to proceed with clinical development of any of these product candidates or that any product candidate will demonstrate a clinical benefit once we advance these candidates to testing in patients. Accordingly, you should consider our prospects in light of the costs, uncertainties, delays and difficulties frequently encountered by preclinical stage biotechnology companies such as ours.

We may not be able to access the financial resources to continue development of, or to enter into any collaborations for, any of our current or potential future product candidates. This may be exacerbated if we

Table of Contents

experience any issues that delay or prevent regulatory approval of, or our ability to commercialize, a product candidate, such as:

•

negative or inconclusive results from our preclinical studies or clinical trials or the clinical trials of others for product candidates similar to ours, leading to a decision or requirement to conduct additional preclinical studies or clinical trials or abandon any or all of our programs;

•

product-related side effects experienced by participants in our clinical trials or by individuals using therapeutics similar to our product candidates;

•

delays in submitting IND applications or comparable foreign applications, or delays or failures to obtain the necessary approvals from regulatory authorities to commence a clinical trial, or a suspension or termination of a clinical trial once commenced;

•

conditions imposed by the FDA or other regulatory authorities regarding the scope or design of our clinical trials;

•

delays in enrolling research subjects in clinical trials;

•

high

drop-out

rates of research subjects;

•

inadequate supply or quality of product candidate components or materials or other supplies necessary for the conduct of our clinical trials;

•

chemistry, manufacturing and control, or CMC, challenges associated with manufacturing and scaling up biologic product candidates to ensure consistent quality, stability, purity and potency among different batches used in clinical trials;

•

greater-than-anticipated clinical trial costs;

•

poor potency or effectiveness of our product candidates during clinical trials;

•

unfavorable FDA or other regulatory authority inspection and review of a clinical trial or manufacturing site;

•

delays as a result of the COVID-19 pandemic or events associated with the pandemic;

•

failure of our third-party contractors or investigators to comply with regulatory requirements or otherwise meet their contractual obligations in a timely manner, or at all;

•

delays and changes in regulatory requirements, policies and guidelines; or

•

the FDA or other regulatory authorities interpreting our data differently than we do.

Further, we and any existing or potential future collaborator may never receive approval to market and commercialize any product candidate. Even if we or any existing or potential future collaborator obtains regulatory approval, the approval may be for targets, disease indications or patient populations that are not as broad as we intended or desired or may require labeling that includes significant use or distribution restrictions or safety warnings. We or an existing or potential future collaborator may also be subject to post-marketing testing requirements to maintain regulatory approval.

None of our current product candidates have ever been tested in humans. We may ultimately discover that our current product candidates do not possess certain properties that we believe are helpful for therapeutic effectiveness and safety or would otherwise support the submission of an IND application on the timelines we expect, or at all. We do not know if the observations we have made regarding our gene circuits generally and our

Table of Contents

product candidates in particular will translate into any clinical response when tested in humans. As an example, while the Tumor-Associated Antigen (TAA) CD33 has been clinically validated as a target for an approved antibody-drug conjugate therapy, it has not been clinically validated as a target for

CAR-NK

CAR-T

therapies, and may not prove to be a clinically sufficient target for the

CAR-NK

therapies we are developing. As a result of these uncertainties related to our gene circuit platform technologies and our product candidates, we may never succeed in developing a marketable product based on our current product candidates. If any of our current or potential future product candidates prove to be ineffective, unsafe or commercially unviable, our entire pipeline could have little, if any, value, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

We are seeking to identify and develop a broad pipeline of product candidates using our gene circuit platform technologies. The scientific research that forms the basis of our efforts to develop product candidates with our platforms is still ongoing. We are not aware of any FDA approved therapeutics utilizing similar technologies as ours. Further, the scientific evidence to support the feasibility of developing therapeutic treatments based on our platform technologies is preliminary. As a result, we are exposed to a number of unforeseen risks and it is difficult to predict the types of challenges and risks that we may encounter during development of our product candidates. For example, we have not tested any of our current product candidates in humans, and our current data is limited to animal models and preclinical cell lines, the results of which may not translate into humans. Further, relevant animal models and assays may not accurately predict the safety and efficacy of our product candidates in humans, and we may encounter significant challenges creating appropriate models and assays for demonstrating the safety and efficacy of our product candidates. In addition, our gene circuit technologies have potential safety risks. For example, if the NOT GATE gene circuit, as described below, engineered into one of our product candidates, such as

SENTI-202,

does not provide a clinically sufficient level of inhibition, it may kill healthy cells that it has been designed to preserve or may cause systemic immune cytotoxicity. As another example, if the small-molecular Regulator Dial does not achieve a clinically sufficient level of control over

IL-12

secretion, either leaky

IL-12

production in the uninduced state or overproduction of

IL-12

Given the novelty of our technologies, we intend to work closely with the FDA and comparable foreign regulatory authorities to evaluate our proposed approaches to obtain regulatory approval for our product candidates; however, due to a lack of comparable experiences, the regulatory pathway with the FDA and comparable regulatory authorities may be more complex and time-consuming relative to other more well-known therapeutics. Even if we obtain human data to support our product candidates, the FDA or comparable foreign regulatory agencies may lack experience in evaluating the safety and efficacy of our product candidates developed using our platforms, which could result in a longer than expected regulatory review process, increase our expected development costs, and delay or prevent commercialization of our product candidates. The validation process takes time and resources, may require independent third-party analyses, and may not be accepted or approved by the FDA and comparable foreign regulatory authorities. We cannot be certain that our approach will lead to the development of approvable or marketable products, alone or in combination with other therapies.

We may not be successful in our efforts to use and expand our gene circuit platform to expand our pipeline of product candidates.

A key element of our strategy is to use and advance our gene circuit platform to design, test and build our portfolio of product candidates focused on allogeneic gene circuit-equipped

CAR-NK

cell therapies for the

Table of Contents

treatment of cancer. Although our research and development efforts to date have resulted in our discovery and preclinical development of

SENTI-202,

and other potential product candidates, none of these product candidates has advanced to clinical development. We cannot assure you that any of our existing product candidates will advance to clinical trials or, if they do, that such trials will demonstrate these product candidates to be safe or effective therapeutics, and we may not be able to successfully develop any product candidates. Even if we are successful in expanding our pipeline of product candidates, any additional product candidates that we identify may not be suitable for clinical development or generate acceptable clinical data, including as a result of being shown to have unacceptable effects or other characteristics that indicate that they are unlikely to be products that will receive marketing approval from the FDA or other regulatory authorities or achieve market acceptance. If we do not successfully develop and commercialize product candidates, we will not be able to generate product revenue in the future.

Although we intend to explore other therapeutic opportunities in addition to the product candidates that we are currently developing, we may fail to identify viable new product candidates for clinical development for a number of reasons. If we fail to identify additional potential product candidates, our business could be materially harmed.

Although a substantial amount of our efforts will focus on the planned clinical trials and potential approval of the current and potential future product candidates we are evaluating, a key element of our strategy is to discover, develop, manufacture and globally commercialize additional targeted therapies beyond our current product candidates to treat various conditions and in a variety of therapeutic areas. Even if we identify investigational therapies that initially show promise, we may fail to successfully develop and commercialize such products for many reasons, including the following:

•

the research methodology used may not be successful in identifying potential investigational therapies;

•

competitors may develop alternatives that render our investigational therapies obsolete;

•

investigational therapies we develop may nevertheless be covered by third parties’ patents or other exclusive rights;

•

an investigational therapy may, on further study, be shown to have harmful side effects or other characteristics that indicate it is unlikely to be effective or otherwise does not meet applicable regulatory criteria;

•

it may take greater human and financial resources than we will possess to identify additional therapeutic opportunities for our product candidates or to develop suitable potential product candidates through internal research programs, thereby limiting our ability to develop, diversify and expand our product portfolio;

•

an investigational therapy may not be capable of being produced in clinical or commercial quantities at an acceptable cost, or at all; and

•

an approved product may not be accepted as safe and effective by trial participants, the medical community or third-party payors.

Identifying new investigational therapies requires substantial technical, financial and human resources, whether or not any investigational therapies are ultimately identified. Because we have limited financial and human resources, we may initially focus on research programs and product candidates for a limited set of indications. As a result, we may forgo or delay pursuit of opportunities with other product candidates or for other indications that later prove to have greater commercial potential or a greater likelihood of success. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. For example, if we do not accurately evaluate the commercial potential or target market for a particular product candidate or technology, we may relinquish valuable rights to that product candidate or technology through collaborations, licensing or other royalty arrangements in cases in which it would have been

Table of Contents

more advantageous for us to retain sole development and commercialization rights to such product candidate or technology.

Accordingly, there can be no assurance that we will ever be able to identify additional therapeutic opportunities for our product candidates or to develop suitable potential product candidates through internal research programs, which could materially adversely affect our future growth and prospects. We may focus our efforts and resources on potential product candidates or other potential programs that ultimately prove to be unsuccessful.

The market, physicians, patients, regulators and potential investors, may not be receptive to our current or potential future product candidates and may be skeptical of the viability and benefits of our gene circuit pipeline technology because it is based on a relatively novel and complex technology.

The market, physicians, patients, regulators and potential investors, may be skeptical of the viability and benefits of our gene circuit pipeline technology or our product candidates because they are based on a relatively novel and complex technology and there can be no assurance that our product candidates or platform technologies will be understood, approved, or accepted. If potential investors are skeptical of the success of our pipeline products, our ability to raise capital and the value of our stock may be adversely affected. If physicians, patients, or regulators do not understand or accept our gene circuit platform technologies or our product candidates, we may be delayed in or unable to develop our product candidates.

Even if regulatory approval is obtained for a product candidate, including

SENTI-202,

SENTI-301

and

SENTI-401,

we may not generate or sustain revenue from sales of approved products. Market acceptance of our gene circuit platform technologies and our current and potential future product candidates, if approved, will depend on, among other factors:

•

the timing of our receipt of any marketing and commercialization approvals;

•

the terms of any approvals and the countries in which approvals are obtained;

•

the safety and efficacy of our product candidates and gene circuit technologies in general;

•

the prevalence and severity of any adverse side effects associated with our product candidates;

•

limitations or warnings contained in any labeling approved by the FDA or other regulatory authority;

•

relative convenience and ease of administration of our product candidates;

•

the success of our physician education programs;

•

the availability of coverage and adequate government and third-party payor reimbursement;

•

the pricing of our products, particularly as compared to alternative treatments; and

•

availability of alternative effective treatments for the disease indications our product candidates are intended to treat and the relative risks, benefits and costs of those treatments.

If any product candidate we commercialize fails to achieve market acceptance, it could have a material adverse effect on our business, financial condition, results of operations and prospects.

The occurrence of serious complications or side effects in connection with use of our product candidates, either in clinical trials or post-approval, could lead to discontinuation of our clinical development programs, refusal of regulatory authorities to approve our product candidates or, post-approval, revocation of marketing authorizations or refusal to approve applications for new indications, which could severely harm our business, prospects, operating results and financial condition.

Undesirable side effects caused by any of our current or potential future product candidates could cause regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the

Table of Contents

delay or denial of regulatory approval by the FDA or other regulatory authorities. While we have not yet initiated clinical trials for

SENTI-202,

SENTI-301,

SENTI-401

or any other product candidate, it is likely that there will be side effects associated with their use. Results of our clinical trials could reveal a high and unacceptable severity and prevalence of these side effects. For example, if the NOT GATE gene circuit engineered into one of our product candidates, such as

SENTI-202,

IL-12

secretion, either leaky

IL-12

production in the uninduced state or overproduction of

IL-12

in the induced state may result in systemic immune toxicity. It is possible that safety events or concerns such as these or others could negatively affect the development of our product candidates, including adversely affecting patient enrollment among the patient populations that we intend to treat. In such an event, our trials could be suspended or terminated, and the FDA or other regulatory authorities could order us to cease further development of or deny approval of a product candidate for any or all targeted indications. Such side effects could also affect patient recruitment or the ability of enrolled patients to complete the trial or result in potential product liability claims. To date, we have not observed any such effects in our preclinical studies, but there can be no guarantee that our current or future product candidates will not cause such effects in clinical trials. Any of these occurrences may materially and adversely affect our business and financial condition and impair our ability to generate revenues.

Further, clinical trials by their nature utilize a sample of the potential patient population. With a limited number of patients and limited duration of exposure, rare and severe side effects of a product candidate may only be uncovered when a significantly larger number of patients are exposed to the product candidate or when patients are exposed for a longer period of time.

In the event that any of our current or potential future product candidates receives regulatory approval and we or others identify undesirable side effects caused by one of these products, any of the following events could occur, which could result in the loss of significant revenue to us and materially and adversely affect our results of operations and business:

•

regulatory authorities may withdraw their approval of the product or seize the product;

•

we may be required to recall the product or change the way the product is administered to patients;

•

additional restrictions may be imposed on the marketing of the particular product or the manufacturing processes for the product or any component thereof;

•

we may be subject to fines, injunctions or the imposition of civil or criminal penalties;

•

regulatory authorities may require the addition of labeling statements, such as a “black box” warning or a contraindication;

•

we may be required to create a Medication Guide outlining the risks of such side effects for distribution to patients;

•

we could be sued and held liable for harm caused to patients;

•

the product may become less competitive; and

•

our reputation may suffer.

Any of these events could prevent us from achieving or maintaining market acceptance of the particular product candidate, if approved, and could significantly harm our business, results of operations and prospects.

While we believe our pipeline will yield multiple INDs, we may not be able to file INDs to commence clinical trials on the timelines we expect, and even if we are able to, the FDA may not permit us to proceed.

We expect our pipeline to yield multiple INDs beginning as early as 2023, including INDs for

SENTI-202

and

SENTI-301.

We cannot be sure that submission of an IND will result in the FDA allowing testing and

Table of Contents

clinical trials to begin, or that, once begun, issues will not arise that suspend or terminate such clinical trials. The manufacturing of our product candidates, including

SENTI-202,

SENTI-301

and

SENTI-401,

remains an emerging and evolving field. Accordingly, we expect chemistry, manufacturing and control related topics, including product specifications, will be a focus of IND reviews, which may delay the clearance of INDs. Additionally, even if such regulatory authorities agree with the design and implementation of the clinical trials set forth in an IND or clinical trial application, we cannot guarantee that such regulatory authorities will not change their requirements in the future.

In addition to the submission of an IND to the FDA before initiation of a clinical trial in the United States, certain human clinical trials involving recombinant or synthetic nucleic acid molecules are subject to oversight of institutional biosafety committees, or IBCs, as set forth in the NIH Guidelines for Research Involving Recombinant or Synthetic Nucleic Acid Molecules, or NIH Guidelines. Under the NIH Guidelines, recombinant and synthetic nucleic acids are defined as: (i) molecules that are constructed by joining nucleic acid molecules and that can replicate in a living cell (i.e., recombinant nucleic acids); (ii) nucleic acid molecules that are chemically or by other means synthesized or amplified, including those that are chemically or otherwise modified but can base pair with naturally occurring nucleic acid molecules (i.e., synthetic nucleic acids); or (iii) molecules that result from the replication of those described in (i) or (ii). Specifically, under the NIH Guidelines, supervision of human gene transfer trials includes evaluation and assessment by an IBC, a local institutional committee that reviews and oversees research utilizing recombinant or synthetic nucleic acid molecules at that institution. The IBC assesses the safety of the research and identifies any potential risk to public health or the environment, and such review may result in some delay before initiation of a clinical trial. While the NIH Guidelines are not mandatory unless the research in question is being conducted at or sponsored by institutions receiving NIH funding of recombinant or synthetic nucleic acid molecule research, many companies and other institutions not otherwise subject to the NIH Guidelines voluntarily follow them.

Interim, topline and preliminary data that we announce or publish from time to time for any clinical trials that we initiate may change as more patient data become available or as additional analyses are conducted, and as the data are subject to audit and verification procedures that could result in material changes in the final data.

From time to time, we may publicly disclose interim, preliminary or topline data from our preclinical studies and clinical trials, which is based on a preliminary analysis of then-available data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the data related to the particular trial. We also make assumptions, estimations, calculations and conclusions as part of our analyses of data, and we may not have received or had the opportunity to fully and carefully evaluate all data. As a result, the interim, preliminary or topline results that we report may differ from future results of the same trials, or different conclusions or considerations may qualify such results, once additional data have been received and fully evaluated. Topline data also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, topline data should be viewed with caution until the final data are available. From time to time, we may also disclose interim, preliminary or topline data from our clinical studies. Interim, topline or preliminary data from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available. Adverse differences between preliminary, topline or interim data and final data could significantly harm our business prospects.

Further, others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the value of the particular program, the approvability or commercialization of the particular product candidate or product and the value of our company in general. In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is based on what is typically extensive information, and you or others may not agree with what we determine is the material or otherwise appropriate information to include in our disclosure, and any information we determine not to disclose may ultimately be deemed significant with respect to future decisions, conclusions, views, activities or otherwise regarding a particular product, product

Table of Contents

candidate or our business. If the topline data that we report differ from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, and commercialize, our product candidates may be harmed, which could harm our business, operating results, prospects or financial condition.

We and our collaborators may not achieve projected discovery and development milestones and other anticipated key events in the time frames that we or they announce, which could have an adverse impact on our business and could cause our stock price to decline.

From time to time, we expect that we will make public statements regarding the expected timing of certain milestones and key events, such as the commencement and completion of preclinical and

IND-enabling

studies in our product candidate discovery programs with collaborators as well as the commencement and completion of planned clinical trials in those programs. The actual timing of these events can vary dramatically due to a number of factors such as delays or failures in our or any future collaborators’product candidate discovery and development programs, the amount of time, effort and resources committed by us and any future collaborators, and the numerous uncertainties inherent in the development of therapies. As a result, there can be no assurance that our or any future collaborators’ programs will advance or be completed in the time frames we or they announce or expect. If we or any collaborators fail to achieve one or more of these milestones or other key events as planned, our business could be materially adversely affected, and the price of our common stock could decline.

Clinical trials are expensive, time-consuming and difficult to design and implement.

Human clinical trials are expensive and difficult to design and implement, in part because they are subject to rigorous regulatory requirements. Because our current and potential future product candidates are based on new technologies and discovery approaches, we expect that they will require extensive research and development and have substantial manufacturing and processing costs. In addition, the FDA or other regulatory authorities may require us to perform additional testing before commencing clinical trials and be hesitant to allow us to enroll patients impacted with our targeted disease indications in our future clinical trials. If we are unable to enroll patients impacted by our targeted disease indications in our future clinical trials, we would be delayed in obtaining potential

proof-of-concept

data in humans, which could extend our development timelines. In addition, costs to treat patients and to treat potential side effects that may result from our product candidates may be significant. Accordingly, our clinical trial costs are likely to be high and could have a material adverse effect on our business, financial condition, results of operations and prospects.

If we encounter difficulties enrolling patients in our clinical trials, our clinical development activities could be delayed or otherwise adversely affected.

We may not be able to initiate or continue any clinical trials for our current or potential future product candidates if we are unable to locate and enroll a sufficient number of eligible patients to participate in these trials as required by the FDA or other regulatory authorities. We cannot predict how difficult it will be to enroll patients for trials in the indications we are studying. We may experience difficulties in patient enrollment in our clinical trials for a variety of reasons. The enrollment of patients depends on many factors, including:

•

the severity of the disease under investigation;

•

the patient eligibility criteria defined in the clinical trial protocol;

•

the size of the patient population required for analysis of the trial’s primary endpoints;

•

the proximity and availability of clinical trial sites for prospective patients;

•

willingness of physicians to refer their patients to our clinical trials;

•

our ability to recruit clinical trial investigators with the appropriate competencies and experience;

Table of Contents

•

clinicians’ and patients’ perceptions as to the potential advantages of the product candidate being studied in relation to other available therapies, including any new drugs that may be approved for the indications we are investigating;

•

our ability to obtain and maintain patient consents;

•

the risk that patients enrolled in clinical trials will drop out of the trials before completion; and

•

factors we may not be able to control, such as current or potential pandemics, including the ongoing

COVID-19 pandemic,

that may limit the availability of patients, principal investigators or staff or clinical sites to participate in our clinical trials.

In addition, our future clinical trials will compete with other clinical trials for product candidates that are in the same therapeutic areas as our product candidates, and this competition will reduce the number and types of patients available to us, because some patients who might have opted to enroll in our trials may instead opt to enroll in a trial being conducted by one of our competitors. Since the number of qualified clinical investigators is limited, we expect to conduct some of our clinical trials at the same clinical trial sites that some of our competitors use, which will reduce the number of patients who are available for our clinical trials at such clinical trial sites. Additionally, because some of our clinical trials will be in patients with advanced disease who may experience disease progression or adverse events independent from our product candidates, such patients may be unevaluable for purposes of the trial and, as a result, we may require additional enrollment. Delays in patient enrollment may result in increased costs or may affect the timing or outcome of the planned clinical trials, which could prevent completion of these trials and adversely affect our ability to advance the development of our product candidates.

If clinical trials for our product candidates are prolonged, delayed or stopped, we may be unable to seek or obtain regulatory approval and commercialize our product candidates on a timely basis, or at all, which would require us to incur additional costs and delay our receipt of any product revenue.

We may experience delays in our ongoing or future preclinical studies or clinical trials, and we do not know whether future preclinical studies or clinical trials will begin on time, need to be redesigned, enroll an adequate number of patients on time or be completed on schedule, if at all. The commencement or completion of these clinical trials could be substantially delayed or prevented by many factors, including:

•

further discussions with the FDA or comparable foreign regulatory authorities regarding the scope or design of our clinical trials, including the endpoint measures required for regulatory approval and our statistical plan;

•

the limited number of, and competition for, suitable study sites and investigators to conduct our clinical trials, many of which may already be engaged in other clinical trial programs with similar patients, including some that may be for the same indication as our product candidates;

•

any delay or failure to obtain timely approval or agreement to commence a clinical trial in any of the countries where enrollment is planned;

•

inability to obtain sufficient funds required for a clinical trial;

•

clinical holds on, or other regulatory objections to, a new or ongoing clinical trial;

•

delay or failure to manufacture sufficient quantities or inability to produce quantities of consistent quality, purity and potency of the product candidate for our clinical trials;

•

delay or failure to reach agreement on acceptable clinical trial agreement terms or clinical trial protocols with prospective sites or CROs, the terms of which can be subject to extensive negotiation and may vary significantly among different sites or CROs;

•

delay or failure to obtain institutional review board, or IRB, or ethics committee approval to conduct a clinical trial at a prospective site;

Table of Contents

•

the FDA or other comparable foreign regulatory authorities may require us to submit additional data or impose other requirements before permitting us to initiate a clinical trial;

•

slower than expected rates of patient recruitment and enrollment;

•

failure of patients to complete the clinical trial;

•

the inability to enroll a sufficient number of patients in studies to ensure adequate statistical power to detect statistically significant treatment effects;

•

unforeseen safety issues, including severe or unexpected drug-related adverse effects experienced by patients, including possible deaths;

•

lack of efficacy or failure to measure a statistically significant clinical benefit within the dose range with an acceptable safety margin during clinical trials;

•

termination of our clinical trials by one or more clinical trial sites;

•

inability or unwillingness of patients or clinical investigators to follow our clinical trial protocols;

•

inability to monitor patients adequately during or after treatment by us or our CROs;

•

our CROs or clinical study sites failing to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or at all, deviating from the protocol or dropping out of a study;

•

inability to address any noncompliance with regulatory requirements or safety concerns that arise during the course of a clinical trial;

•

the impact of, and delays related to, health epidemics such as the

COVID-19

pandemic;

•

the need to suspend, repeat or terminate clinical trials as a result

of non-compliance with

regulatory requirements, inconclusive or negative results or unforeseen complications in testing; and

•

the suspension or termination of our clinical trials upon a breach or pursuant to the terms of any agreement with, or for any other reason by, any future strategic collaborator that have responsibility for the clinical development of any of our product candidates.

Changes in regulatory requirements, policies and guidelines may also occur and we may need to significantly modify our clinical development plans to reflect these changes with appropriate regulatory authorities. These changes may require us to renegotiate terms with CROs or resubmit clinical trial protocols to IRBs

for re-examination, which

may impact the costs, timing or successful completion of a clinical trial. Our clinical trials may be suspended or terminated at any time by us, the FDA, other regulatory authorities, the IRB overseeing the clinical trial at issue, any of our clinical trial sites with respect to that site, or us.

Any failure or significant delay in commencing or completing clinical trials for our product candidates, any failure to obtain positive results from clinical trials, any safety concerns related to our product candidates, or any requirement to conduct additional clinical trials or other testing of our product candidates beyond those that we currently contemplate would adversely affect our ability to obtain regulatory approval and our commercial prospects and ability to generate product revenue will be diminished.

If we decide to seek orphan drug designation for one or more of our product candidates, we may be unsuccessful or may be unable to maintain the benefits associated with orphan drug designation for our current or future product candidates that we may develop.

Under the Orphan Drug Act, the FDA may designate a product candidate as an orphan drug if it is a drug or biologic product intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals annually in the United States, or where there is no reasonable expectation that

Table of Contents

the cost of developing the product will be recovered from sales in the United States. We may seek Orphan Drug Designation for certain indications for our product candidates in the future. Orphan Drug Designation neither shortens the development time or regulatory review time of a drug nor gives the drug any advantage in the regulatory review or approval process. Orphan Drug Designation can entitle a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages and

user-fee

waivers.

In addition, if a product candidate with an Orphan Drug Designation receives the first marketing approval for the indication for which it has such designation, the product is entitled to a period of marketing exclusivity, which precludes the FDA from approving another marketing application for the same drug for the same indication for seven years. The FDA may reduce the seven-year exclusivity if the same drug from a competitor demonstrates clinical superiority to the product with orphan exclusivity or if the FDA finds that the holder of the orphan exclusivity has not shown that it can assure the availability of sufficient quantities of the orphan product to meet the needs of patients with the disease or condition for which the drug was designated. Even if one of our product candidates receives orphan exclusivity, the FDA can still approve other drugs that have a different active ingredient for use in treating the same indication or disease.

In addition, exclusive marketing rights in the United States may be limited if we seek approval for an indication broader than the orphan-designated indication or may be lost if the FDA later determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantities of the product to meet the needs of patients with the rare disease or condition. Further, even if we obtain orphan drug exclusivity for a product, that exclusivity may not effectively protect the product from competition because different drugs with different active moieties can be approved for the same condition, and while we may seek orphan drug designation for our product candidates, we may never receive such designations. In addition, the FDA may reevaluate the Orphan Drug Act and its regulations and policies. We do not know if, when, or how the FDA may change the orphan drug regulations and policies in the future, and it is uncertain how any changes might affect our business. Depending on what changes the FDA may make to its orphan drug regulations and policies, our business could be adversely impacted.

We may not be able to conduct, or contract with others to conduct, animal testing in the future, which could harm our research and development activities.

Certain laws and regulations relating to drug development require us to test our product candidates on animals before initiating clinical trials involving humans. Animal testing activities have been the subject of controversy and adverse publicity. Animal rights groups and other organizations and individuals have attempted to stop animal testing activities by pressing for legislation and regulation in these areas and by disrupting these activities through protests and other means. To the extent the activities of these groups are successful, our research and development activities may be interrupted or delayed.

Risks Related to Third Parties

We rely on third parties to conduct our preclinical studies, and plan to rely on third parties to conduct clinical trials, and those third parties may not perform satisfactorily.

We expect to rely on third-party clinical investigators, contract research organizations, or CROs, clinical data management organizations and consultants to design, conduct, supervise and monitor certain preclinical studies and any clinical trials. Because we intend to rely on these third parties and will not have the ability to conduct certain preclinical studies or clinical trials independently, we will have less control over the timing, quality and other aspects of such preclinical studies and clinical trials than we would have had we conducted them on our own. These investigators, CROs and consultants will not be our employees and we will have limited control over the amount of time and resources that they dedicate to our programs. Some of these third parties may terminate their engagements with us at any time. We also expect to have to negotiate budgets and contracts with CROs, clinical trial sites and CMOs and we may not be able to do so on favorable terms, which may result

Table of Contents

in delays to our development timelines and increased costs. If we need to enter into alternative arrangements with, or replace or add any third parties, it would involve substantial cost and require extensive management time and focus, or involve a transition period, and may delay our drug development activities, as well as materially impact our ability to meet our desired clinical development timelines. These third parties may have contractual relationships with other entities, some of which may be our competitors, which may draw time and resources from our programs. The third parties with which we may contract might not be diligent, careful or timely in conducting our preclinical studies or clinical trials, resulting in the preclinical studies or clinical trials being delayed or unsuccessful.

Our reliance on these third parties for such drug development activities will reduce our control over these activities. As a result, we will have less direct control over the conduct, timing and completion of preclinical studies and clinical trials and the management of data developed through preclinical studies and clinical trials than would be the case if we were relying entirely upon our own staff. Nevertheless, we will be responsible for ensuring that each of our studies and trials is conducted in accordance with applicable protocol, legal and regulatory requirements and scientific standards, including good laboratory practice, or GLP, good clinical practice, or GCP, cGMP, and cGTP and our reliance on third parties does not relieve us of our regulatory responsibilities. For example, we will remain responsible for ensuring that each of our clinical trials is conducted in accordance with the general investigational plan and protocols for the trial. Moreover, the FDA and other regulatory authorities require us to comply with GCP standards, regulations for conducting, recording and reporting the results of clinical trials to assure that data and reported results are reliable and accurate and that the rights, integrity and confidentiality of trial participants are protected. Regulatory authorities enforce these GCP requirements through periodic inspections of trial sponsors, principal investigators and trial sites. If we or any of our CROs fail to comply with applicable GCP requirements, the clinical data generated in our clinical trials may be deemed unreliable and the FDA, European Medicines Agency, or EMA, or other regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. There can be no assurance that upon inspection by a given regulatory authority, such regulatory authority will determine that any of our clinical trials substantially comply with GCP regulations. In addition, our clinical trials must be conducted with product candidates produced under cGMP regulations and will require a large number of test patients. Our failure or any failure by these third parties to comply with these regulations or to recruit a sufficient number of patients, may require us to repeat clinical trials, which would delay the regulatory approval process. Moreover, our business may be implicated if any of these third parties violates FDA regulatory requirements as well as federal or state healthcare laws and regulations or healthcare privacy and security laws.

If these third parties do not successfully carry out their contractual duties, meet expected deadlines or conduct our clinical trials in accordance with regulatory requirements or our stated protocols, or if these third parties need to be replaced, we will not be able to obtain, or may be delayed in obtaining, marketing approvals for our product candidates and will not be able to, or may be delayed in our efforts to, successfully commercialize our product candidates. As a result, our financial results and the commercial prospects for our product candidates would be harmed, our costs could increase and our ability to generate revenue could be delayed.

We depend on strategic partnerships and collaboration arrangements, such as our collaboration arrangements with Spark Therapeutics, Inc., or Spark, and Bluerock Therapeutics, Inc., or Bluerock, for the application of our gene circuit platform technology to the development and commercialization of potential product candidates in certain indications, and if these arrangements are unsuccessful, this could impair our ability to generate additional revenues and materially harm our results of operations.

Our business strategy for exploiting the potential of our gene circuit platform technology is dependent upon maintaining our current arrangements and establishing new arrangements with strategic partners, research collaborators and other third parties. We currently have collaboration agreements with Spark and Bluerock. These collaboration agreements provide for, among other things, research funding and significant future

Table of Contents

payments should certain development, regulatory and commercial milestones be achieved. Under these arrangements, our collaborators are typically responsible for:

•

electing to advance product candidates through preclinical and into clinical development;

•

conducting clinical development and obtaining required regulatory approvals for product candidates; and

•

commercializing any resulting products.

As a result, we may not be able to conduct these collaborations in the manner or on the time schedule we currently contemplate, which may negatively impact our business operations.

Additionally, the development and commercialization of potential product candidates under our collaboration agreements could be substantially delayed, and our ability to receive future funding could be substantially impaired if one or more of our collaborators:

•

shifts its priorities and resources away from our collaborations due to a change in business strategies, or a merger, acquisition, sale or downsizing of its company or business unit;

•

ceases development in therapeutic areas which are the subject of our collaboration;

•

fails to select a product candidate for advancement into preclinical development, clinical development, or subsequent clinical development into a marketed product;

•

changes the success criteria for a particular product candidate, thereby delaying or ceasing development of such product candidate;

•

significantly delays the initiation or conduct of certain activities which could delay our receipt of milestone payments tied to such activities, thereby impacting our ability to fund our own activities;

•

develops a product candidate that competes, either directly or indirectly, with our product candidates;

•

does not obtain the requisite regulatory approval of a product candidate;

•

does not successfully commercialize a product candidate;

•

encounters regulatory, resource or quality issues and be unable to meet demand requirements;

•

exercises its rights under the agreement to terminate the collaboration, or otherwise withdraws support for, or otherwise impairs development under the collaboration;

•

disagrees on the research, development or commercialization of a product candidate resulting in a delay in milestones, royalty payments or termination of research and development activities for such product candidate; and

•

uses our proprietary information or intellectual property in such a way as to jeopardize our rights in such property.

In addition, the termination of our existing collaborations or any future strategic partnership or collaboration arrangement that we enter into may prevent us from receiving any milestone, royalty payment, sharing of profits, and other benefits under such agreement. Furthermore, disagreements with these parties could require or result in litigation or arbitration, which would be time-consuming and expensive. Any of these events could have a material adverse effect on our ability to develop and commercialize any of our product candidates and may adversely impact our business, prospects, financial condition, and results of operations.

We may not be able to enter into additional strategic transactions on acceptable terms, if at all, which could adversely affect our ability to develop and commercialize current and potential future product candidates and technologies, impact our cash position, increase our expense and present significant distractions to our management.

From time to time, we consider strategic transactions, such as collaborations, regional partnerships for the

co-development

and/or

co-commercialization

of our product candidates in selected territories, acquisitions of

Table of Contents

companies, asset purchases, joint ventures,

out-

in-licensing

of product candidates or technologies and biomanufacturing partnerships involving our manufacturing facilities and gene circuit platform technology. For example, we will evaluate and, if strategically attractive, seek to enter into collaborations, including with biotechnology or biopharmaceutical companies, contract development manufacturing organizations or hospitals. The competition for collaborators is intense, and the negotiation process is time-consuming and complex. If we are not able to enter into strategic transactions, we may not have access to required liquidity or expertise to further develop our potential future product candidates or our gene circuit platform. Any such collaboration, or other strategic transaction, may require us to incur

non-recurring

or other charges, increase our near- and long-term expenditures and pose significant integration or implementation challenges or disrupt our management or business.

We also may acquire additional technologies and assets, form strategic alliances or create joint ventures with third parties that we believe will complement or augment our existing business, but we may not be able to realize the benefit of acquiring such assets. Conversely, any new collaboration that we do enter into may be on terms that are not optimal for us, our product candidates or our technologies. These transactions would entail numerous operational and financial risks, including:

•

exposure to unknown liabilities;

•

disruption of our business and diversion of our management’s time and attention in order to negotiate and manage a collaboration or develop acquired products, product candidates or technologies;

•

incurrence of substantial debt or dilutive issuances of equity securities to pay transaction consideration or costs;

•

higher-than-expected collaboration, acquisition or integration costs, write-downs of assets or goodwill or impairment charges, increased amortization expenses;

•

difficulty and cost in facilitating the collaboration or combining the operations and personnel of any acquired business;

•

impairment of relationships with key suppliers, manufacturers or customers of any acquired business due to changes in management and ownership; and

•

the inability to retain key employees of any acquired business.

Accordingly, although there can be no assurance that we will undertake or successfully complete any transactions of the nature described above, any transactions that we do complete may be subject to the foregoing or other risks and our business could be materially harmed by such transactions. Conversely, any failure to enter any collaboration or other strategic transaction that would be beneficial to us could delay the development and potential commercialization of our product candidates and technologies and have a negative impact on the competitiveness of any product candidate or technology that reaches market.

In addition, to the extent that any future collaborators terminate a collaboration agreement, we may be forced to independently develop our current and future product candidates and technologies, including funding preclinical studies or clinical trials, assuming marketing and distribution costs and maintaining, enforcing and defending intellectual property rights, or, in certain instances, abandon product candidates and technologies altogether, any of which could result in a change to our business plan and have a material adverse effect on our business, financial condition, results of operations and prospects.

Risks Related to Manufacturing

The manufacture of biopharmaceutical products is complex and requires significant expertise, including the development of advanced manufacturing techniques and process controls. The process of manufacturing our

Table of Contents

product candidates is also extremely susceptible to product loss due to contamination, equipment failure or improper installation or operation of equipment, operator error, contamination and inconsistency in yields, variability in product characteristics and difficulties in scaling the production process. Even minor deviations from normal manufacturing processes could result in reduced production yields, product defects and other supply disruptions. If microbial, viral or other contaminations are discovered in our product candidates or the manufacturing facilities in which they are made, the facilities may need to be closed for an extended period of time to investigate and remedy the contamination. As a result of the complexities, the cost to manufacture biologics in general, and our cell-based product candidates in particular, is generally higher than traditional small molecule chemical compounds, and the manufacturing process is less reliable and is more difficult to reproduce.

Any adverse developments affecting manufacturing operations for our product candidates, if any are approved, may result in shipment delays, inventory shortages, lot failures, product withdrawals or recalls, or other interruptions in the supply of our products. We may also have to take inventory write-offs and incur other charges and expenses for products that fail to meet specifications, undertake costly remediation efforts or seek more costly manufacturing alternatives. Furthermore, it is too early to estimate our cost of goods sold. The actual cost to manufacture our product candidates could be greater than we expect because we are early in our development efforts.

Construction of our planned

in-house

manufacturing may be delayed or, even if completed, supply of our product candidates for preclinical and clinical development may become limited or interrupted or may not be of satisfactory quantity or quality, and we will experience delays if we are unable to operate our own manufacturing facility and are required to relay on third party

back-up

manufacturers.

A key to our strategy is operating our own manufacturing facility. We have initiated construction in June 2021 of a dedicated

in-house,

state-of-the-art

facility to support clinical and commercial-scale production of allogeneic NK cell product candidates in accordance with cGMP and cGTP requirements. We anticipate that this facility will become operational in time to support initial clinical trials for our lead product candidates. Initial manufacturing efforts at our planned facility will focus on our two lead product candidates,

SENTI-202

and

SENTI-301.

The construction and commissioning of our planned facility may be delayed or may not be completed. As such, we cannot assure that our preclinical or future clinical development product supplies and commercial supplies will not be limited or interrupted. In particular, any change in our plans to construct and operate our own facility, including any decision to rely on third party

back-up

manufacturers, could require significant effort and expertise because there may be a limited number, if any, qualified third-party replacements. We do not currently have arrangements in place for a redundant or second-source supply in the event our planned facility does not become operational. Any delays resulting in manufacturing our product candidates could impede, delay, limit or prevent our drug development efforts, which could harm our business, result of operations, financial condition and prospects. Additionally, we may pursue a biomanufacturing partnership in which we grant a third party certain rights to use our manufacturing facility for the manufacture of third parties’ products or product candidates, which could divert our manufacturing capacity and management resources from the manufacture of our product candidates.

We do not currently produce our product candidates in quantities sufficient for preclinical and clinical development, and we do not currently have arrangements with any third parties to produce them for us. We cannot be sure that the manufacturing processes employed by us or the technologies that we incorporate for manufacturing will result in viable or scalable yields of our product candidates that will be safe, be effective, and meet market demand.

The manufacturing process for a product candidate is subject to FDA and other regulatory authority review. We and any third-party manufacturers we may contract with must meet applicable manufacturing requirements and undergo rigorous facility and process validation tests required by regulatory authorities in order to comply

Table of Contents

with regulatory standards, such as cGMP and cGTP. In the event that we or any third-party manufacturer fails to comply with such requirements or to perform obligations in relation to quality, timing or otherwise, or if our supply of components or other materials becomes limited or interrupted for other reasons, we may be forced to or enter into an agreement with another third party, which we may not be able to do on reasonable terms, or at all. In some cases, the technical skills or technology required to manufacture our current and future product candidates may be difficult or impossible to transfer to a third party and a feasible alternative may not exist. If we are required to change manufacturing facilities or manufacturers for any reason, we will be required to verify that the new facilities and procedures comply with quality standards and with all applicable regulations and guidelines. We will also need to verify, such as through a manufacturing comparability study, that any new manufacturing process will produce our product candidate according to the specifications previously submitted to the FDA or another regulatory authority. The delays associated with the verification of a new manufacturing could negatively affect our ability to develop product candidates in a timely manner or within budget. In addition, changes in manufacturers often involve changes in manufacturing procedures and processes, which could require that we conduct bridging studies between our prior clinical supply used in our clinical trials and that of any new manufacturer. We may be unsuccessful in demonstrating the comparability of clinical supplies which could require the conduct of additional clinical trials.

If we receive regulatory approval for any product candidate and we are unable to for any reason to produce sufficient quantities of the product in our own facility, and we are unable to obtain or maintain third-party manufacturing on commercially reasonable terms, we may not be able to commercialize the product candidate successfully. Our or a third party’s failure to execute on our manufacturing requirements and comply with cGMP and cGTP could adversely affect our business in a number of ways, including:

•

an inability to initiate or continue clinical trials of product candidates under development;

•

delay in submitting regulatory applications, or receiving regulatory approvals, for product candidates;

•

loss of the cooperation of potential future collaborators;

•

subjecting third-party manufacturing facilities or our potential future manufacturing facilities to additional inspections by regulatory authorities;

•

requirements to cease distribution or to recall batches of product candidates; and

•

in the event of approval to market and commercialize a product candidate, an inability to meet commercial demands for our products.

Our future

in-house

manufacturing facility and any third-party manufacturers that we use may be unable to successfully scale the manufacturing of our current or potential future product candidates in sufficient quality and quantity, which would delay or prevent us from developing our current and potential future product candidates and commercializing approved products candidates, if any. We have never operated a cGMP facility before.

In order to conduct clinical trials for our current and potential future product candidates or to commercialize any approved product candidates, we will need to manufacture large quantities of these product candidates. We expect to use our

in-house

manufacturing facility to produce required quantities of our product candidates upon its planned completion in 2022. We, or any manufacturing partners, may be unable to successfully increase the manufacturing capacity for any current or potential future product candidate in a timely or cost-effective manner, or at all. In addition, quality issues may arise during

scale-up

activities and may result in lower yields than initially expected. While we believe our planned cGMP facility will be sufficiently scalable to produce commercial quantities, any significant revisions to the manufacturing process may create delays, which could negatively impact our overall development timelines. In addition, we have never operated a cGMP facility before. We may encounter difficulties in operating the facility or meeting the requirements of the FDA or other regulatory authorities that we have not anticipated. If we cannot successfully scale the manufacture of any current or potential future product candidate in sufficient quality and quantity, the development, testing, clinical

Table of Contents

trials and commercialization of that product candidate may be delayed or infeasible and regulatory approval or commercial launch of any potential resulting product may be delayed or not obtained, which could significantly harm our business.

We are exposed to a number of risks related to our supply chain for the materials required to manufacture our product candidates.

Manufacturing our product candidates is highly complex and requires sourcing specialty materials. Many of the risks associated with the complexity of manufacturing our final products are applicable to the manufacture and supply of the raw materials. In particular, these starting materials are subject to inconsistency in yields, variability in characteristics, contamination, difficulties in scaling the production process and defects. Similar minor deviations in the manufacturing process for these starting materials could result in supply disruption and reduced production yields for our final product. In addition, we rely on third parties for the supply of these materials exposing us to similar risks of reliance on third parties as described above with respect to the manufacturing and supply of our drug products.

Our manufacturing processes requires many reagents, some of which are drug substance intermediates used in our manufacturing processes to bring about chemical or biological reactions, and other specialty materials and equipment, some of which are manufactured or supplied by small companies with limited resources and experience to support commercial production. We currently depend on a limited number of vendors for certain materials and equipment used in the manufacture of our product candidates. Some of these suppliers may not have the capacity to support commercial products manufactured under cGMP by biopharmaceutical firms or may otherwise be

ill-equipped

to support our needs. Reagents and other key materials from these suppliers may have inconsistent attributes and introduce variability into our manufactured product candidates, which may contribute to variable patient outcomes and possible adverse events. We also do not have supply contracts with many of these suppliers and may not be able to obtain supply contracts with them on acceptable terms or at all. Accordingly, we may experience delays in receiving key materials and equipment to support clinical or commercial manufacturing.

For some of these reagents, equipment, and materials, we rely and may in the future rely on sole source vendors or a limited number of vendors. An inability to continue to source product from any of these suppliers, which could be due to regulatory actions or requirements affecting the supplier, adverse financial or other strategic developments experienced by a supplier, labor disputes or shortages, unexpected demands, or quality issues, could adversely affect our ability to satisfy demand for our product candidates, which could adversely and materially affect our product sales and operating results or our ability to conduct clinical trials, either of which could significantly harm our business. Additionally, in response to governmental

shelter-in-place

orders resulting from the ongoing

COVID-19

pandemic, third-party suppliers and manufacturers on whom we rely may from time to time be required to limit their

on-site

staff’s availability to conduct activities at their respective facilities, and may encounter problems with shortages of qualified personnel and key contractors, and delays or pauses in the production and delivery of laboratory equipment, materials and supplies necessary for the manufacture of our product candidates. These problems may include workforce reductions, employee absenteeism and attrition, and supply chain failures or delays relating to the ongoing

COVID-19

pandemic or other events affecting raw material supply or manufacturing capabilities.

As we continue to develop and scale our manufacturing process, we expect that we will need to obtain rights to and supplies of certain materials and equipment to be used as part of that process. We may not be able to obtain rights to such materials on commercially reasonable terms, or at all, and if we are unable to alter our process in a commercially viable manner to avoid the use of such materials or find a suitable substitute, it would have a material adverse effect on our business. Even if we are able to alter our process so as to use other materials or equipment, such a change may lead to a delay in our clinical development and/or commercialization plans. If such a change occurs for a product candidate that is already in clinical testing, the change may require us to perform both comparability studies and to collect additional data from patients prior to undertaking more advanced clinical trials.

Table of Contents

Changes in methods of product candidate manufacturing or formulation may result in the need to perform new clinical trials, which would require additional costs and cause delay.

As product candidates are developed through preclinical to late-stage clinical trials towards approval and commercialization, it is common that various aspects of the development program, such as manufacturing methods and formulation, are altered along the way in an effort to optimize yield and manufacturing batch size, minimize costs and achieve consistent quality and results. Such changes carry the risk that they will not achieve these intended objectives. Any of these changes could cause our product candidates to perform differently and affect the results of ongoing, planned or future clinical trials conducted with the altered materials. This could delay completion of clinical trials, require the conduct of bridging clinical trials or the repetition of one or more clinical trials, increase clinical trial costs, delay approval of our product candidates and jeopardize our ability to commence product sales and generate revenue.

Risks Related to Our Business and Operations

If the market opportunities for our current and potential future product candidates, including

SENTI-202,

SENTI-301

and

SENTI-401,

are smaller than we believe they are, our future product revenues may be adversely affected, and our business may suffer.

Our understanding of the number of people who suffer from diseases that our current product candidates may be able to treat are based on estimates. These estimates may prove to be incorrect, and new studies may reduce the estimated incidence or prevalence of these diseases. The number of patients in the United States or elsewhere may turn out to be lower than expected, may not be otherwise amenable to treatment with our current or potential future product candidates or patients may become increasingly difficult to identify and access, all of which would adversely affect our business prospects and financial condition. In particular, the treatable population for our candidates may further be reduced if our estimates of addressable populations are erroneous or

sub-populations

of patients do not derive benefit from our product candidates.

Further, there are several factors that could contribute to making the actual number of patients who receive our current or potential future product candidates less than the potentially addressable market. These include the lack of widespread availability of, and limited reimbursement for, new therapies in many underdeveloped markets.

The development and commercialization of cell and gene therapies is highly competitive. We compete with a variety of large pharmaceutical companies, multinational biopharmaceutical companies, other biopharmaceutical companies and specialized biotechnology companies, as well as technology and/or therapeutics being developed at universities and other research institutions. Our competitors are often larger and better funded than we are. Our competitors have developed, are developing or will develop product candidates and processes competitive with ours. Competitive therapeutic treatments include those that have already been approved and accepted by the medical community and any new treatments that are currently in development or that enter the market. We believe that a significant number of product candidates are currently under development, and may become commercially available in the future, for the treatment of conditions for which we may try to develop product candidates. There is intense and rapidly evolving competition in the biotechnology and biopharmaceutical fields. We believe that while our gene circuit platform, its associated intellectual property, the characteristics of our current and potential future product candidates and our scientific and technical

know-how

together give us a competitive advantage in this space, competition from many sources remains.

Table of Contents

Many of our competitors have significantly greater financial, technical, manufacturing, marketing, sales and supply resources or experience than we do. If we successfully obtain approval for any product candidate, we will face competition based on many different factors, including the safety and effectiveness of our product candidates, the ease with which our product candidates can be administered, the timing and scope of regulatory approvals for these product candidates, the availability and cost of manufacturing, marketing and sales capabilities, price, reimbursement coverage and patent position. Competing products and product candidates could present superior treatment alternatives, including by being more effective, safer, less expensive or marketed and sold more effectively than any products we may develop. Competitive products and product candidates may make any product we develop obsolete or noncompetitive before we recover the expense of developing and commercializing such product. Such competitors could also recruit our employees, which could negatively impact our level of expertise and our ability to execute our business plan.

Any inability to attract and retain qualified key management, technical personnel and employees would impair our ability to implement our business plan.

Our success largely depends on the continued service of key executive management, advisors and other specialized personnel, including Timothy Lu, our Chief Executive Officer, Philip Lee, our Chief Technology Officer, Curt Herberts III, our Chief Operating Officer and Deborah Knobelman, our Chief Financial Officer. Our senior management may terminate their employment with us at any time and will continue to be able to do so after the closing of the Business Combination. We do not maintain “key person” insurance for any of our employees. The loss of one or more members of our executive team, management team or other key employees or advisors could delay our research and development programs and have a material adverse effect on our business, financial condition, results of operations and prospects.

Recruiting and retaining qualified scientific and clinical personnel and, if we progress the development of any of our product candidates, commercialization, manufacturing and sales and marketing personnel, will be critical to our success. The loss of the services of members of our senior management or other key employees could impede the achievement of our research, development and commercialization objectives and seriously harm our ability to successfully implement our business strategy. Furthermore, replacing members of our senior management and key employees may be difficult and may take an extended period of time because of the limited number of individuals in our industry with the breadth of skills and experience required to successfully develop, gain regulatory approval of and commercialize our product candidates. Our success also depends on our ability to continue to attract, retain and motivate highly skilled

junior, mid-level and

senior managers, as well as junior,

mid-level and

senior scientific and medical personnel. Competition to hire from this limited candidate pool is intense, and we may be unable to hire, train, retain or motivate these key personnel on acceptable terms given the competition among numerous pharmaceutical and biotechnology companies for similar personnel. We also experience competition for the hiring of scientific and clinical personnel from universities and research institutions. In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our research and development and commercialization strategy. Our consultants and advisors may have commitments under consulting or advisory contracts with other entities that may limit their availability to us. If we are unable to continue to attract and retain high-quality personnel, our ability to pursue our growth strategy will be limited.

We may experience difficulties in managing our growth and expanding our operations.

We have limited experience in therapeutic development. As our current and potential future product candidates enter and advance through preclinical studies and any clinical trials, we will need to expand our development, regulatory and manufacturing capabilities or contract with other organizations to provide these capabilities for us.

To manage our anticipated future growth, we will continue to implement and improve our managerial, operational, and financial systems, expand our facilities, and continue to recruit and train additional qualified

Table of Contents

personnel. Due to our limited financial resources and the complexity in managing a company with such anticipated growth, we may not be able to effectively manage the expansion of our operations or recruit and train additional qualified personnel. In addition, we have limited experience in managing the manufacturing processes necessary for making cell and gene therapies. The expansion of our operations may lead to significant costs and may divert our management and business development resources. Any inability to manage growth could delay the execution of our business plans or disrupt our operations.

In addition, future growth imposes significant added responsibilities on members of management, including: identifying, recruiting, integrating, maintaining, and motivating additional employees; managing our internal development efforts effectively, including the clinical and FDA review process for our product candidates, while complying with our contractual obligations to contractors and other third parties; and improving our operational, financial and management controls, reporting systems and procedures.

We may also experience difficulties in the discovery and development of potential future product candidates using our gene circuit platform if we are unable to meet demand as we grow our operations. In the future, we also expect to have to manage additional relationships with collaborators, suppliers and other organizations. Our ability to manage our operations and future growth will require us to continue to improve our operational, financial and management controls, reporting systems and procedures and secure adequate facilities for our operational needs. We may not be able to implement improvements to our management information and control systems in an efficient or timely manner and may discover deficiencies in existing systems and controls.

If any of our product candidates is approved for marketing and commercialization in the future and we are unable to develop sales, marketing and distribution capabilities on our own or enter into agreements with third parties to perform these functions on acceptable terms, we will be unable to successfully commercialize any such future products.

We currently have no sales, marketing or distribution capabilities or experience. We will need to develop internal sales, marketing and distribution capabilities to commercialize each current and potential future product candidate that gains, if ever, FDA or other regulatory authority approval, which would be expensive and time-consuming, or enter into collaborations with third parties to perform these services. If we decide to market any approved products directly, we will need to commit significant financial and managerial resources to develop a marketing and sales force with technical expertise and supporting distribution, administration and compliance capabilities. If we rely on third parties with such capabilities to market any approved products or decide to

co-promote

products with third parties, we will need to establish and maintain marketing and distribution arrangements with third parties, and there can be no assurance that we will be able to enter into such arrangements on acceptable terms or at all. In entering into third-party marketing or distribution arrangements, any revenue we receive will depend upon the efforts of the third parties and we cannot assure you that such third parties will establish adequate sales and distribution capabilities or be successful in gaining market acceptance for any approved product. If we are not successful in commercializing any product approved in the future, either on our own or through third parties, our business and results of operations could be materially and adversely affected.

Our potential future international operations may expose us to business, political, operational and financial risks associated with doing business outside of the United States.

Our business is subject to risks associated with conducting business internationally. Some of our future clinical trials may be conducted outside of the United States and we may enter into key supply or other business. Furthermore, if we or any future collaborator succeeds in developing any products, we anticipate marketing them in the European Union and other jurisdictions in addition to the United States. If approved, we or any future

Table of Contents

collaborator may hire sales representatives and conduct physician and patient association outreach activities outside of the United States. Doing business internationally involves a number of risks, including but not limited to:

•

multiple, conflicting and changing laws and regulations such as those relating to privacy, data protection and cybersecurity, tax laws, export and import restrictions, employment laws, regulatory requirements and other governmental approvals, permits and licenses;

•

failure by us to obtain and maintain regulatory approvals for the commercialization of our product candidates in various countries;

•

rejection or qualification of foreign clinical trial data by the competent authorities of other countries;

•

additional potentially relevant third-party patent rights;

•

complexities and difficulties in obtaining, maintaining, protecting and enforcing our intellectual property rights;

•

difficulties in staffing and managing foreign operations;

•

complexities associated with managing multiple payor reimbursement regimes, government payors or patient

self-pay

systems;

•

limits in our ability to penetrate international markets;

•

financial risks, such as longer payment cycles, difficulty collecting accounts receivable, the impact of local and regional financial crises on demand and payment for our products and exposure to foreign currency exchange rate fluctuations;

•

natural disasters, political and economic instability, including wars, terrorism and political unrest, outbreak of disease (including the

COVID-19

pandemic), boycotts, curtailment of trade and other business restrictions;

•

certain expenses including, among others, expenses for travel, translation and insurance; and

•

regulatory and compliance risks that relate to anti-corruption compliance and record-keeping that may fall within the purview of the U.S. Foreign Corrupt Practices Act, its accounting provisions or its anti-bribery provisions or provisions of anti-corruption or anti-bribery laws in other countries.

Any of these factors could harm our ongoing international operations and supply chain, as well as any future international expansion and operations and, consequently, our business, financial condition, prospects and results of operations.

Our business entails a significant risk of product liability, and our inability to obtain sufficient insurance coverage could have a material adverse effect on our business, financial condition, results of operations and prospects.

As we conduct preclinical studies and future clinical trials of our current and potential future product candidates, we will be exposed to significant product liability risks inherent in the development, testing, manufacturing and marketing of these product candidates. Product liability claims could delay or prevent completion of our development programs. If we succeed in marketing products, such claims could result in an FDA investigation of the safety and effectiveness of our products, our manufacturing processes and facilities or our marketing programs and potentially a recall of our products or more serious enforcement action, limitations on the approved indications for which they may be used or suspension or withdrawal of approvals. Regardless of the merits or eventual outcome, liability claims may also result in decreased demand for our products, injury to our reputation, costs to defend the related litigation, a diversion of management’s time and our resources, substantial monetary awards to trial participants or patients and a decline in our stock price. Any insurance we have or may obtain may not provide sufficient coverage against potential liabilities. Furthermore, clinical trial and product liability insurance is becoming increasingly expensive. As a result, any future collaborators or we

Table of Contents

may be unable to obtain sufficient insurance at a reasonable cost to protect us against losses caused by product liability claims that could have a material adverse effect on our business, financial condition, results of operations and prospects.

Our employees, principal investigators, consultants and commercial collaborators may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements.

We are exposed to the risk of fraud or other misconduct by our employees, principal investigators, consultants and commercial collaborators. Misconduct by employees could include intentional failures to comply with FDA regulations, provide accurate information to the FDA, comply with manufacturing standards we may establish, comply with federal and state healthcare fraud and abuse laws and regulations, report financial information or data accurately or disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Such misconduct could also involve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. It is not always possible to identify and deter misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a material adverse effect on our business and financial condition, including the imposition of significant criminal, civil and administrative fines or other sanctions, such as monetary penalties, damages, fines, disgorgement, imprisonment, exclusion from participation in government-funded healthcare programs, such as Medicare and Medicaid, integrity obligations, reputational harm and the curtailment or restructuring of our operations.

We depend on sophisticated information technology systems and data processing to operate our business. If we experience security or data privacy breaches or other unauthorized or improper access to, use of, or destruction of our proprietary or confidential data, employee data or personal data, we may face costs, significant liabilities, harm to our brand and business disruption.

We rely on information technology systems and data processing that we or our service providers, collaborators, consultants, contractors or partners operate to collect, process, transmit and store electronic information in our

day-to-day

operations, including a variety of personal data, such as name, mailing address, email addresses, phone number and potentially clinical trial information. Additionally, we, and our service providers, collaborators, consultants, contractors or partners, do or will collect, receive, store, process, generate, use, transfer, disclose, make accessible, protect and share personal information, health information and other information to host or otherwise process some of our anticipated future clinical data and that of users, develop our products, to operate our business, for clinical trial purposes, for legal and marketing purposes, and for other business-related purposes. Our internal computer systems and data processing and those of our third-party vendors, consultants, collaborators, contractors or partners, including future CROs may be vulnerable to a cyber-attack (including supply chain cyber-attacks), malicious intrusion, breakdown, destruction, loss of data privacy, actions or inactions by our employees or contractors that expose security vulnerabilities, theft or destruction of intellectual property or other confidential or proprietary information, business interruption or other significant security incidents. As the cyber-threat landscape evolves, these attacks are growing in frequency, level of persistence, sophistication and intensity, and are becoming increasingly difficult to detect. In addition to traditional computer “hackers,” threat actors, software bugs, malicious code (such as viruses and worms), employee theft or misuse,

denial-of-service

attacks (such as credential stuffing), phishing and ransomware attacks, sophisticated nation-state and nation-state supported actors now engage in attacks (including advanced persistent threat intrusions). These risks may be increased as a result of

COVID-19,

owing to an increase in personnel working remotely and higher reliance on internet technology. Furthermore, because the techniques used to obtain unauthorized access to, or to sabotage, systems change frequently and often are not recognized until launched against a target, we

Table of Contents

may be unable to anticipate these techniques or implement adequate preventative measures. We may also experience security breaches that may remain undetected for an extended period.

There can be no assurance that we, our service providers, collaborators, consultants, contractors or partners will be successful in efforts to detect, prevent or fully recover systems or data from all breakdowns, service interruptions, attacks or breaches of systems that could adversely affect our business and operations and/or result in the loss of critical or sensitive data. Any failure by us or our service providers, collaborators, consultants, contractors or partners to detect, prevent, respond to or mitigate security breaches or improper access to, use of, or inappropriate disclosure of any of this information or other confidential or sensitive information, including patients’ personal data, or the perception that any such failure has occurred, could result in claims, litigation, regulatory investigations and other proceedings, significant liability under state, federal and international law, and other financial, legal or reputational harm to us. Further, such failures or perceived failures could result in liability and a material disruption of our development programs and our business operations, which could lead to significant delays or setbacks in our research, delays to commercialization of our product candidates, lost revenues or other adverse consequences, any of which could have a material adverse effect on our business, results of operations, financial condition, prospects and cashflow. For example, the loss or alteration of clinical trial data from future clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data.

Additionally, applicable laws and regulations relating to privacy, data protection or cybersecurity, external contractual commitments and internal privacy and security policies may require us to notify relevant stakeholders if there has been a security breach, including affected individuals, business partners and regulators. Such disclosures are costly, and the disclosures or any actual or alleged failure to comply with such requirements could lead to a materially adverse impact on the business, including negative publicity, a loss of confidence in our services or security measures by our business partners or breach of contract claims. There can be no assurance that the limitations of liability in our contracts would be enforceable or adequate or would otherwise protect us from liabilities or damages if we fail to comply with applicable data protection laws, privacy policies or other data protection obligations related to information security or security breaches.

If we do not comply with laws regulating the protection of the environment and health and human safety, our business could be adversely affected.

Our research, development and manufacturing involve the use of hazardous materials and various chemicals. We maintain quantities of various flammable and toxic chemicals in our facilities that are required for our research, development and manufacturing activities. We are subject to federal, state and local laws and regulations governing the use, manufacture, storage, handling and disposal of these hazardous materials. We believe our procedures for storing, handling and disposing of these materials in our facilities comply with the relevant guidelines of the state of California and the Occupational Safety and Health Administration of the U.S. Department of Labor. Although we believe that our safety procedures for handling and disposing of these materials comply with the standards mandated by applicable regulations, the risk of accidental contamination or injury from these materials cannot be eliminated. If an accident occurs, we could be held liable for resulting damages, which could be substantial. We are also subject to numerous environmental, health and workplace safety laws and regulations, including those governing laboratory procedures, exposure to blood-borne pathogens and the handling of animals and biohazardous materials. Although we maintain workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries to our employees resulting from the use of these materials, this insurance may not provide adequate coverage against potential liabilities. Although we have some environmental liability insurance covering certain of our facilities, we may not maintain adequate insurance for all environmental liability or toxic tort claims that may be asserted against us in connection with our storage or disposal of biological or hazardous materials. Additional federal, state and local laws and regulations affecting our operations may be adopted in the future. We may incur substantial costs to comply with, and substantial fines or penalties if we violate, any of these laws or regulations.

Our business, operations and clinical development plans and timelines could be adversely affected by the effects of health epidemics, including the ongoing

COVID-19 pandemic,

on the manufacturing, clinical trial and other business activities performed by us or by third parties with whom we may conduct business, including our anticipated contract manufacturers, CROs, shippers and others.

Health epidemics could cause significant disruption in our operations and the operations of third-party manufacturers, CROs and other third parties upon whom we rely. For example, in March 2020, the World Health Organization declared

the COVID-19 outbreak

a pandemic. Since then,

COVID-19

has spread to most countries and all 50 states within the United States, and the U.S. government ordered the closure of

all non-essential

businesses, imposed social distancing

measures, “shelter-in-place” orders

and restrictions on travel between the United States, Europe and certain other countries. The global pandemic and government measures taken in response have also had a significant impact on businesses and commerce worldwide, as worker shortages have occurred; supply chains have been disrupted; facilities and production have been suspended across a variety of industries; and demand for certain goods and services, such as medical services and supplies, has spiked, while demand for other goods and services, such as travel, has fallen. In connection

with COVID-19, we

implemented work-from-home policies for most employees. The effects of government orders and our work-from-home policies may negatively impact productivity, disrupt our business and delay our clinical programs and timelines, the magnitude of which will depend, in part, on the length and severity of the restrictions and other limitations on our ability to conduct our business in the ordinary course.

If our relationships with our suppliers or other vendors are terminated or scaled back as a result of

the COVID-19 pandemic

or other health epidemics, we may not be able to enter into arrangements with alternative suppliers or vendors or do so on commercially reasonable terms or in a timely manner. Switching or adding additional suppliers or vendors involves substantial cost and requires management time and focus. In addition, there is a natural transition period when a new supplier or vendor commences work. As a result, delays may occur, which could adversely impact our ability to meet our desired clinical development and any future commercialization timelines. Although we carefully manage our relationships with our suppliers and vendors, there can be no assurance that we will not encounter challenges or delays in the future or that these delays or challenges will not harm our business.

In addition, our preclinical studies and future clinical trials may be affected by

the COVID-19 pandemic.

Clinical site initiation, patient enrollment and activities that require visits to clinical sites, including data monitoring, may be delayed due to prioritization of hospital resources toward

the COVID-19 pandemic

or concerns among patients about participating in clinical trials during a pandemic. Some patients may have difficulty following certain aspects of clinical trial protocols if quarantines impede patient movement or interrupt healthcare services. These challenges may also increase the costs of completing our clinical trials. Similarly, if we are unable to successfully recruit and retain patients and principal investigators and site staff who, as healthcare providers, may have heightened exposure

to COVID-19 or

experience additional restrictions by their institutions, city or state, our preclinical studies and future clinical trial operations could be adversely impacted.

The spread

of COVID-19, which

has caused a broad impact globally, may materially affect us economically. While the potential economic impact brought by, and the duration

of, COVID-19 may

be difficult to assess or predict, a widespread pandemic has resulted in significant volatility for global financial markets, resulting in economic uncertainty that could continue to significantly impact our business and operations and may reduce our ability to access capital, which could in the future negatively affect our liquidity. In addition, a recession or market correction resulting from the spread

of COVID-19 could

materially affect our business and the value of our common stock. In addition, any recurrence or new increases in the rates and severity of

COVID-19

infection could cause other widespread or more severe impacts depending on where infection rates are highest.

Table of Contents

Further, we may experience additional disruptions that could severely impact our business and future clinical trials, including:

•

diversion of healthcare resources away from the conduct of clinical trials, including the diversion of hospitals serving as our clinical trial sites and hospital staff supporting the conduct of our clinical trials;

•

interruption or delays in the operations of the FDA or other regulatory authorities, which may impact review and approval timelines;

•

limitations on employee resources that would otherwise be focused on the conduct of our preclinical studies and clinical trials, including because of sickness of employees or their families or the desire of employees to avoid contact with large groups of people;

•

risk that participants enrolled in our clinical trials will acquire

COVID-19

while the clinical trial is ongoing, which could impact the results of the clinical trial, including by increasing the number of observed adverse events; and

•

refusal of the FDA or other regulatory authorities to accept data from clinical trials in these affected geographies.

In particular, three vaccines for

COVID-19

have been granted Emergency Use Authorization by the FDA, and two of those later received marketing approval. Additional vaccines may be authorized or approved in the future. The resultant demand for vaccines and potential for manufacturing facilities and materials to be commandeered under the Defense Production Act of 1950, or equivalent foreign legislation, may make it more difficult to obtain materials or manufacturing slots for the product candidates needed for our clinical trials, which could lead to delays in these trials. These and similar, and perhaps more severe, disruptions in our operations could have a material adverse effect on our business, results of operations, cash flows, financial condition and/or prospects.

As a result of the

COVID-19

public health emergency, we may be required to develop and implement additional clinical trial policies and procedures designed to help protect subjects from the

COVID-19

virus. The ultimate impact of the

COVID-19

pandemic on our business operations is highly uncertain and subject to change and will depend on future developments, including new regulatory requirements and changes to existing regulations.

The global pandemic

of COVID-19 continues

to evolve rapidly. We do not yet know the full extent of potential delays or impacts on our business, our future clinical trials, healthcare systems or the global economy as a whole that may result from the ongoing

COVID-19

pandemic. However, these effects could have a material impact on our operations, and we continue to monitor

the COVID-19 situation

closely. To the extent

the COVID-19 pandemic

adversely affects our business, results of operations, cash flows, financial condition and/or prospects, it may also have the effect of heightening many of the other risks described in this “Risk Factors” section.

Risks Related to Our Intellectual Property

Our success depends in part on our ability to obtain and maintain protection for our owned and

in-licensed

intellectual property rights and proprietary technology. We rely on a combination of patents, trademarks, trade secret protection and confidentiality agreements, including

in-licenses

of intellectual property rights and biologic materials of others, to protect our current or future platform technologies, product candidates, methods used to manufacture our current or future product candidates and methods for treating patients using our current or future product candidates.

Table of Contents

We own or

in-license

patents and patent applications relating to our platform technologies and product candidates. There is no guarantee that any patents covering our platform technologies or product candidates will issue from the patent applications we own,

in-license

or may file in the future, or, if they do, that the issued claims will provide adequate protection for our platform technologies or product candidates, or any meaningful competitive advantage. Further, there cannot be any assurance that such patents issued will not be infringed, designed around, invalidated by third parties or effectively prevent others from commercializing competitive technologies, products or product candidates.

The patent prosecution process is expensive, complex and time-consuming. Patent license negotiations also can be complex and protracted, with uncertain results. We may not be able to file, prosecute, maintain, enforce or license all necessary or desirable patents and patent applications at a reasonable cost or in a timely manner. It is also possible that we will fail to identify patentable aspects of our research and development output before it is too late to obtain patent protection. The patent applications that we own or

in-license

may fail to result in issued patents, and, even if they do issue as patents, such patents may not cover our current or future technologies or product candidates in the United States or in other countries or provide sufficient protection from competitors. In addition, the coverage claimed in a patent application can be significantly reduced before the patent is issued, and its scope can be reinterpreted after issuance. We do not have exclusive control over the preparation, filing and prosecution of patent applications under certain of our

in-license

agreements, and we may not have the right to control the preparation, filing and prosecution of patent applications, or to maintain the rights to patents, that we

out-license

to third parties. Therefore, these patents and applications may not be prosecuted and enforced in a manner consistent with the best interests of our business. Even if our owned or

in-licensed

patent applications issue as patents, they may not issue in a form that will provide us with any meaningful protection, prevent competitors from competing with us or otherwise provide us with any competitive advantage. Our competitors may be able to circumvent our patents by developing similar or alternative product candidates in a

non-infringing

manner.

Further, although we make reasonable efforts to ensure patentability of our inventions, we cannot guarantee that all of the potentially relevant prior art relating to our owned or

in-licensed

patents and patent applications has been found. For example, publications of discoveries in scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after filing, and in some cases not at all. Additionally, pending patent applications that have been published can, subject to certain limitations, be later amended in a manner that could cover our platform technologies, our product candidates, or the use of our technologies. We thus cannot know with certainty whether we or our licensors were the first to file for patent protection of such inventions. In addition, the USPTO might require that the term of a patent issuing from a pending patent application be disclaimed and limited to the term of another patent that is commonly owned or names a common inventor. There is no assurance that all potentially relevant prior art relating to our owned or

in-licensed

patent applications has been found. For this reason, and because there is no guarantee that any prior art search is absolutely correct and comprehensive, we may be unaware of prior art that could be used to invalidate an issued patent or to prevent our owned or

in-licensed

patent applications from issuing as patents. Invalidation of any of our patent rights, including

in-licensed

patent rights, could materially harm our business.

Moreover, the patent positions of biotechnology companies like ours are generally uncertain because they may involve complex legal and factual considerations that have, in recent years, been the subject of legal development and change. The relevant patent laws and their interpretation, both inside and outside of the United States, is also uncertain. Changes in either the patent laws or their interpretation in the United States and other jurisdictions may diminish our ability to protect our platform technology or product candidates and could affect the value of such intellectual property. In particular, our ability to stop third parties from making, using, selling, offering to sell or importing products that infringe, misappropriate or otherwise violate our intellectual property will depend in part on our success in obtaining and enforcing patent claims that cover our platform technology, product candidates, inventions and improvements. We cannot guarantee that patents will be granted with respect to any of our owned or licensed pending patent applications or with respect to any patent applications we may

Table of Contents

file or license in the future, nor can we be sure that any patents that may be granted to us or our licensors in the future will be commercially useful in protecting our products, the methods of use or manufacture of those products. Additionally, third parties, including our former employees and collaborators, may challenge the ownership or inventorship of our patent rights to claim that they are entitled to ownership and inventorship interest, and we may not be successful in defending against such claims. However, we are not currently facing any such challenges. Moreover, issued patents do not guarantee the right to practice our technology in relation to the commercialization of our products. Issued patents only allow us to block—in some cases—potential competitors from practicing the claimed inventions of the issued patents.

The issuance, scope, validity, enforceability and commercial value of our pending patent rights are uncertain. The standards applied by the United States Patent and Trademark Office, or USPTO, and foreign patent offices in granting patents are not always certain and moreover, are not always applied uniformly or predictably. For example, there is no uniform worldwide policy regarding patentable subject matter or the scope of claims allowable in patents. Our pending and future patent applications may not result in patents being issued in the United States or in other jurisdictions which protect our technology or products or which effectively prevent others from commercializing competitive technologies and products. Changes in either the patent laws or interpretation of the patent laws in the United States and other countries may diminish the value of our owned or

in-licensed

patent applications or narrow the scope of any patent protection we may obtain from our owned or

in-licensed

patent applications. In addition, the laws of foreign countries may not protect our rights to the same extent as the laws of the United States.

Further, patents and other intellectual property rights in the pharmaceutical and biotechnology space are evolving and involve many risks and uncertainties. For example, third parties may have blocking patents that could be used to prevent us from commercializing our product candidates and any future product candidates and practicing our proprietary technology, and any issued patents may be challenged, invalidated or circumvented, which could limit our ability to stop competitors from marketing related products or could limit the term of patent protection that otherwise may exist for our product candidate and any future product candidates. In addition, the scope of the rights granted under any issued patents may not provide us with protection or competitive advantages against competitors or other parties with similar technology. Additionally, our competitors may initiate legal proceedings, such as declaratory judgment actions in federal court or reexaminations or an

inter partes

review at the USPTO in an attempt to invalidate or narrow the scope of our patents. However, we are not currently facing any such proceedings. Furthermore, our competitors or other parties may independently develop similar technologies that are outside the scope of the rights granted under any issued patents. For these reasons, we may face competition with respect to our product candidates and any future product candidates. Moreover, because of the extensive time required for development, testing and regulatory review of a potential product, it is possible that, before any particular product candidate can be commercialized, any patent protection for such product candidate may expire or remain in force for only a short period following commercialization, thereby reducing the commercial advantage the patent provides.

Even if patents do successfully issue from our owned or

in-licensed

patent application, and even if such patents cover our current or any future technologies or product candidates, third parties may challenge their validity, enforceability or scope, which may result in such patents being narrowed, invalidated, or held unenforceable. Any successful challenge to these patents or any other patents owned by or licensed to us could deprive us of rights necessary for the successful commercialization of any current or future technologies or product candidates that we may develop. Likewise, if patent applications we own or have

in-licensed

with respect to our development programs and current or future technologies or product candidates fail to issue, if their breadth or strength is threatened, or if they fail to provide meaningful exclusivity, other companies could be dissuaded from collaborating with us to develop current or future technologies or product candidates. Lack of valid and enforceable patent protection could threaten our ability to commercialize current or future products and could prevent us from maintaining exclusivity with respect to the invention or feature claimed in the patent applications. Any failure to obtain or any loss of patent protection could have a material adverse impact on our business and ability to achieve profitability. We may be unable to prevent competitors from entering the market

Table of Contents

with a product that is similar or identical to any of our current or potential future product candidates or from utilizing technologies similar to those in our gene circuit platform technologies.

The filing of a patent application or the issuance of a patent is not conclusive as to its ownership, inventorship, scope, patentability, validity or enforceability. Issued patents and patent applications may be challenged in the courts and in the patent office in the United States and abroad. For example, our patent applications or patent applications filed by our licensors, or any patents that grant therefrom, may be challenged through third-party submissions, opposition or derivation proceedings. By further example, any issued patents that may result from our owned or

in-licensed

patent applications may be challenged through reexamination,

inter partes

review or post-grant review proceedings before the USPTO, or in declaratory judgment actions or counterclaims. An adverse determination in any such submission, proceeding or litigation could prevent the issuance of, reduce the scope of, invalidate or render unenforceable our owned or

in-licensed

patent rights; result in the loss of exclusivity; limit our ability to stop others from using or commercializing similar or identical platforms and product candidates; or allow third parties to compete directly with us without payment to us. In addition, if the breadth or strength of protection provided by any patents that might result from our owned or

in-licensed

patent applications is threatened, it could dissuade companies from collaborating with us to license, develop or commercialize current or future platforms or product candidates. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.

Moreover, we currently

co-own

certain patent applications with third parties and may in the future

co-own

additional patents and patent applications with third parties. If we are unable to obtain an exclusive license to any such third-party

co-owners’

interest in such patents or patent application, such

co-owners

may be able to license their rights to other third parties, including our competitors, and our competitors could market competing products and technology. We may need the cooperation of any such

co-owners

to enforce such patents against third parties, and such cooperation may not be provided to us. Any of the foregoing could have a material adverse effect on our competitive position, business prospects and financial conditions.

Our

in-licensed

patent rights may be subject to a reservation of rights by one or more third parties, such as the U.S. government. In addition, our rights in such inventions may be subject to certain requirements to manufacture product candidates embodying such inventions in the United States. Any exercise by the U.S. government of such rights could harm our competitive position, business, financial condition, results of operations and prospects.

The patent protection and patent prosecution for some of our product candidates and technologies may be dependent on third parties.

While we normally seek to obtain the right to control prosecution, maintenance and enforcement of the patents relating to our product candidates and technologies, there may be times when the filing and prosecution activities for patents and patent applications relating to our product candidates and technologies are controlled by our licensors or collaborators. Our licensors may not successfully prosecute the patent applications to which we are licensed. Even if patents are issued in respect of these patent applications, our licensors may fail to maintain these patents, may determine not to pursue litigation against other companies that are infringing these patents, or may pursue such litigation less aggressively than we would.

If any of our licensors or collaborators fail to prosecute, maintain and enforce such patents and patent applications in a manner consistent with the best interests of our business, including by payment of all applicable fees for patents covering our product candidates and technologies, we could lose our rights to the intellectual property or our exclusivity with respect to those rights, our ability to develop and commercialize those product candidates and technologies may be adversely affected and we may not be able to prevent competitors from making, using and selling competing product candidates. In addition, even where we have the right to control patent prosecution of patents and patent applications we have licensed to and from third parties, we may still be adversely affected or prejudiced by actions or inactions of our licensees, our current and future licensors and their counsel that took place prior to the date upon which we assumed control over patent prosecution.

Table of Contents

Further, we may have limited control over the manner in which our licensors initiate an infringement proceeding against a third-party infringer of the intellectual property rights, or defend certain of the intellectual property that is licensed to us. It is possible that the licensors’ infringement proceeding(s) or defense activities may be less vigorous than had we conducted them ourselves.

We may be unable to acquire or

in-license

any relevant third-party intellectual property rights that we identify as necessary or important to our business operations.

Because our development programs may in the future require the use of proprietary rights held by third parties, the growth of our business may depend in part on our ability to acquire,

in-license

or use these third-party proprietary rights. We may be unable to acquire or

in-license

any compositions, methods of use, processes or other third-party intellectual property rights from third parties that we identify as necessary for our product candidates. The licensing of third-party intellectual property rights is a competitive area, and more established companies may pursue strategies to license or acquire third-party intellectual property rights that we may consider attractive or necessary. More established companies may have a competitive advantage over us due to their size, capital resources and greater clinical development and commercialization capabilities. In addition, companies that perceive us to be a competitor may be unwilling to assign or license rights to us. We also may be unable to license or acquire third-party intellectual property rights on terms that would allow us to make an appropriate return on our investment or at all. Even if we are able to obtain a license, it may be

non-exclusive,

thereby giving our competitors access to the same technologies licensed to us. If we are unable to license such technology, or if we are forced to license such technology on unfavorable terms, our business could be materially harmed. If we are unable to obtain a necessary license, we may be unable to develop or commercialize the affected current or future product candidates, which could materially harm our business, and the third parties owning such intellectual property rights could seek either an injunction prohibiting our sales, or, with respect to our sales, an obligation on our part to pay royalties or other forms of compensation. Any of the foregoing could harm our competitive position, business, financial condition, results of operations and prospects.

Further, our licensors may retain certain rights under their agreements with us, including the right to use the underlying technology for noncommercial academic and research use, to publish general scientific findings from research related to the technology, and to make customary scientific and scholarly disclosures of information relating to the technology. It is difficult to monitor whether our licensors limit their use of the technology to these uses, and we could incur substantial expenses to enforce our rights to our licensed technology in the event of misuse.

Additionally, some intellectual property that we have

in-licensed

may have been discovered through government funded programs and thus may be subject to federal regulations such as

“march-in”

rights, certain reporting requirements and a preference for U.S.-based companies. Compliance with such regulations may limit our exclusive rights, and limit our ability to contract with

non-U.S.

manufacturers. As a result, the U.S. government may have certain rights to intellectual property embodied in our current or future product candidates pursuant to the Bayh-Dole Act of 1980, or Bayh-Dole Act, and implementing regulations. These U.S. government rights in certain inventions developed under a government-funded program include a

non-exclusive,

non-transferable,

irrevocable worldwide license to use inventions for any governmental purpose. In addition, the U.S. government has the right to require us or our licensors to grant exclusive, partially exclusive, or

non-exclusive

licenses to any of these inventions to a third party if it determines that: (i) adequate steps have not been taken to commercialize the invention; (ii) government action is necessary to meet public health or safety needs; or (iii) government action is necessary to meet requirements for public use under federal regulations (also referred to as

“march-in

rights”). The U.S. government also has the right to take title to these inventions if we, or the applicable licensor, fail to disclose the invention to the government and fail to file an application to register the intellectual property within specified time limits. These time limits have recently been changed by regulation, and may change in the future. Intellectual property generated under a government funded program is also subject to certain reporting requirements, compliance with which may require us or the applicable licensor to expend substantial resources. In addition, the U.S. government requires that any products embodying the subject

Table of Contents

invention or produced through the use of the subject invention be manufactured substantially in the United States. The manufacturing preference requirement can be waived if the owner of the intellectual property can show that reasonable but unsuccessful efforts have been made to grant licenses on similar terms to potential licensees that would be likely to manufacture substantially in the United States or that under the circumstances domestic manufacture is not commercially feasible. This preference for U.S. manufacturers may limit our ability to contract with

non-U.S.

product manufacturers for products covered by such intellectual property. To the extent any of our current or future intellectual property is generated through the use of U.S. government funding, the provisions of the Bayh-Dole Act may similarly apply.

We currently, and in the future may continue to, enter into agreements involving licenses or collaborations that provide for access or sharing of intellectual property. These intellectual property-related agreements may impose certain obligations and restrictions on our ability to develop and commercialize our product candidates and technologies that are the subject of such licenses.

We license rights from third parties to use certain intellectual property relevant to one or more of our current and future product candidates. In the future, we may need to obtain additional licenses from others to advance our research and development activities or allow the commercialization of our current and future product candidates we may identify and pursue. These existing license agreements impose, and any future license agreements we enter into are likely to impose, various development, commercialization, funding, milestone, royalty, diligence, sublicensing, insurance, patent prosecution and enforcement or other obligations on us. For example, we are a party to three license agreements with the U.S. Department of Health and Human Services, as represented by the National Cancer Institute, or the NCI, for intellectual property relevant to our product candidates. For a more detailed description of the license agreements with NCI, see the section titled “Business—Material License Agreements.”

In addition, certain of our future agreements with third parties may limit or delay our ability to consummate certain transactions, may impact the value of those transactions, or may limit our ability to pursue certain activities. For example, we may in the future enter into license agreements that are not assignable or transferable, or that require the licensor’s express consent in order for an assignment or transfer to take place.

Further, we or our licensors, if any, may fail to identify patentable aspects of inventions made in the course of development and commercialization activities before it is too late to obtain patent protection on them. Therefore, we may miss potential opportunities to strengthen our patent position. It is possible that defects of form in the preparation or filing of our patents or patent applications may exist, or may arise in the future, for example with respect to proper priority claims, inventorship, claim scope, or requests for patent term adjustments. If we or our licensors fail to establish, maintain or protect such patents and other intellectual property rights, such rights may be reduced or eliminated. If our licensors are not fully cooperative or disagree with us as to the prosecution, maintenance or enforcement of any patent rights, such patent rights could be compromised. If there are material defects in the form, preparation, prosecution, or enforcement of our patents or patent applications, such patents may be invalid and/or unenforceable, and such applications may never result in valid, enforceable patents. Any of these outcomes could impair our ability to prevent competition from third parties, which may have an adverse impact on our business, financial conditions, results of operations and prospects.

Furthermore, we may not have the right to control the preparation, filing, prosecution, maintenance, enforcement and defense of patents and patent applications that we license from third parties. In certain circumstances, our licensed patent rights are subject to our reimbursing our licensors for their patent prosecution and maintenance costs. If our licensors and future licensors fail to prosecute, maintain, enforce and defend patents we may license, or lose rights to licensed patents or patent applications, our licensed rights may be reduced or eliminated. In such circumstances, our right to develop and commercialize any of our products or product candidates that is the subject of such licensed rights could be materially adversely affected. Even where we have the right to control patent prosecution of patents and patent applications under license from third parties,

Table of Contents

we may still be adversely affected or prejudiced by actions or inactions of our predecessors or licensors and their counsel that took place prior to us assuming control over patent prosecution.

Our technology acquired or licensed currently or in the future from various third parties is or may be subject to retained rights. Our predecessors or licensors do and may retain certain rights under their agreements with us, including the right to use the underlying technology for

non-commercial

academic and research use, to publish general scientific findings from research related to the technology, and to make customary scientific and scholarly disclosures of information relating to the technology. It is difficult to monitor whether our predecessors or licensors limit their use of the technology to these uses, and we could incur substantial expenses to enforce our rights to our licensed technology in the event of misuse.

If we are limited in our ability to utilize acquired or licensed technologies, or if we lose our rights to critical

in-licensed

technology, we may be unable to successfully develop,

out-license,

market and sell our product candidates, which could prevent or delay new product introductions. Our business strategy depends on the successful development of acquired technologies and licensed technology into commercial product candidates. Therefore, any limitations on our ability to utilize these technologies may impair our ability to develop,

out-license

or market and sell our product candidates.

If we fail to comply with our obligations under any existing or future license, collaboration or other intellectual property-related agreements, we may be required to pay damages and could lose intellectual property rights that may be necessary for developing, commercializing and protecting our current or future technologies or product candidates or we could lose certain rights to grant sublicenses.

We have certain obligations to third-party licensors from whom we license certain patent rights that are relevant to one or more current and future product candidates. In the future, we may need to obtain additional licenses from other third parties to advance our research and development activities or allow the commercialization of our current and future product candidates. Our existing license agreements impose, and any future license agreements we enter into are likely to impose, various development, commercialization, funding, milestone, royalty, diligence, sublicensing, insurance, patent prosecution and enforcement or other obligations on us. For a more detailed description of our existing license agreements, see the section titled “Business—Material License Agreements.” If we breach any of these obligations, including diligence obligations with respect to development and commercialization of product candidates covered by the intellectual property licensed to us, or use the intellectual property licensed to us in an unauthorized manner or we are subject to bankruptcy-related proceedings, we may be required to pay damages and the licensor may have the right to terminate the respective agreement or materially modify the terms of the license, such as by rendering currently exclusive licenses

non-exclusive.

License termination or modification could result in our inability to develop, manufacture and sell products that are covered by the licensed intellectual property or could enable a competitor to gain access to the licensed intellectual property.

In certain circumstances, our licensed patent rights are subject to our reimbursing our licensors for their patent prosecution and maintenance costs. If our licensors and future licensors fail to prosecute, maintain, enforce and defend patents we may license, or lose rights to licensed patents or patent applications, our licensed rights may be reduced or eliminated. In such circumstances, our right to develop and commercialize any of our products or product candidates that is the subject of such licensed rights could be materially adversely affected.

Our current or future licensors may own or control intellectual property that has not been licensed to us and, as a result, we may be subject to claims, regardless of their merit, that we are infringing, misappropriating or otherwise violating the licensor’s intellectual property rights. In addition, while we cannot currently determine the amount of the royalty obligations we would be required to pay on sales of future products if infringement or misappropriation were found, those amounts could be significant. The amount of our future royalty obligations will depend on the technology and intellectual property we use in products that we successfully develop and commercialize, if any. Therefore, even if we successfully develop and commercialize products, we may be unable to achieve or maintain profitability.

Table of Contents

Disputes may arise between us and our present and future licensors regarding intellectual property subject to a licensing agreement, including:

•

the scope of rights granted under the license agreement and other interpretation-related issues, including but not limited to our right to transfer or assign the license;

•

whether and the extent to which our product candidates, technology and processes infringe on intellectual property of the licensor that is not subject to the licensing agreement;

•

our right to sublicense patents and other rights to third parties, including the terms and conditions therefor;

•

our diligence obligations with respect to the development and commercialization of our product candidates that are covered by the license agreement, and what activities satisfy those diligence obligations;

•

our right to transfer or assign the license;

•

the inventorship and ownership of inventions and

know-how

resulting from the joint creation or use of intellectual property by our licensors and us and our collaborators; and

•

the priority of invention of patented technology.

If disputes over intellectual property that we license in the future prevent or impair our ability to maintain our licensing arrangements on acceptable terms, we may not be able to successfully develop and commercialize the affected product candidates, which would have a material adverse effect on our business, financial condition, results of operations and prospects.

In addition, the agreements under which we currently license intellectual property or technology from the NCI and other third parties are complex, and certain provisions in such agreements may be susceptible to multiple interpretations. The resolution of any contract interpretation disagreement that may arise could narrow what we believe to be the scope of our rights to the relevant intellectual property or technology, or increase what we believe to be our financial or other obligations under the relevant agreement, either of which could have a material adverse effect on our business, financial condition, results of operations and prospects. Moreover, if disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrangements on commercially acceptable terms, we may be unable to successfully develop and commercialize the affected product candidates, which could have a material adverse effect on our business, financial conditions, results of operations and prospects.

In addition, while we currently do not have any liens, security interests, or other encumbrances on the intellectual property that we own, we may, in the future, need to obtain a loan or a line of credit that will require that we put up our intellectual property as collateral to our lenders or creditors. If we do so, and we violate the terms of any such loan or credit agreement, our lenders or creditors may take possession of our collateral intellectual property, including the rights to receive proceeds derived from such intellectual property.

Patent terms may not be able to protect our competitive position for an adequate period of time with respect to our current or future technologies or product candidates.

Patents have a limited lifespan. The term of individual patents and applications in our portfolio depends upon the legal term of patents in the countries in which they are obtained. In most countries in which we file, including the United States, the patent term is 20 years from the earliest date of filing a

non-provisional

patent application. Extensions of patent term may be available, but there is no guarantee that we would have patents eligible for extension, or that we would succeed in obtaining any particular extension—and no guarantee any such extension would confer patent term for a sufficient period of time to exclude others from commercializing product candidates similar or identical to ours. In the United States, the term of a patent may be eligible for

Table of Contents

patent term adjustment, which permits patent term restoration as compensation for delays incurred at the USPTO during the patent prosecution process. In addition, for patents that cover an

FDA-approved

drug, the Drug Price Competition and Patent Term Restoration Act of 1984, or the Hatch-Waxman Act, permits a patent term extension of up to five years beyond the expiration of the patent. While the length of the patent term extension is related to the length of time the drug is under regulatory review, patent term extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval, and only one patent per approved drug—and only those claims covering the approved drug, a method for using it or a method for manufacturing it—may be extended under the Hatch-Waxman Act. Similar provisions are available in Europe and other foreign jurisdictions to extend the term of a patent that covers an approved drug. In the future, if and when our products receive FDA approval or applicable approval in other jurisdictions, we expect to apply for patent term extensions on issued patents covering those products in the United States and other jurisdiction where such extensions are available; however, there is no guarantee that the applicable authorities, including the FDA in the United States, will agree with our assessment of whether such extensions should be granted, and if granted, the length of such extensions. We also may not be granted an extension because of, for example, failing to exercise due diligence during the testing phase or regulatory review process, failing to apply within applicable deadlines, failing to apply prior to expiration of relevant patents or otherwise failing to satisfy applicable requirements. If we are unable to obtain patent term extension or the term of any such extension is less than we request, the period during which we can enforce our patent rights for the applicable product candidate will be shortened and our competitors may obtain approval to market competing products sooner. As a result, our revenue from applicable products could be reduced. Further, if this occurs, our competitors may be able to launch their products earlier by taking advantage of our investment in development and clinical trials along with our clinical and preclinical data. This could have a material adverse effect on our business and ability to achieve profitability.

The life of a patent and the protection it affords are limited. As a result, our owned and

in-licensed

patent portfolio provides us with limited rights that may not last for a sufficient period of time to exclude others from commercializing product candidates similar or identical to ours. Even if patents covering our product candidates are obtained, once the patent life has expired, we may be open to competition from competitive products, including generics or biosimilars. For example, given the large amount of time required for the research, development, testing and regulatory review of new product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. As a result, our owned and licensed patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.

Changes in U.S. patent law or the patent law of other countries or jurisdictions could diminish the value of patents in general, thereby impairing our ability to protect our current or any future technologies or product candidates.

Changes in either the patent laws or interpretation of the patent laws in the United States or elsewhere could increase the uncertainties and costs surrounding the prosecution of patent applications and the enforcement or defense of issued patents. The United States has enacted and implemented wide-ranging patent reform legislation. On September 16, 2011, the Leahy-Smith America Invents Act, or the Leahy-Smith Act, was signed into law, which could increase the uncertainties and costs surrounding the prosecution of our owned or

in-licensed

patent applications and the enforcement or defense of any future owned or

in-licensed

issued patents. The Leahy-Smith Act includes a number of significant changes to U.S. patent law. These include provisions that affect the way patent applications are prosecuted, redefine prior art, may affect patent litigation and switch the U.S. patent system from a

“first-to-invent”

system to a

“first-to-file”

system. Under a

first-to-file

system, assuming the other requirements for patentability are met, the first inventor to file a patent application generally will be entitled to the patent on an invention regardless of whether another inventor had made the invention earlier. A third party that files a patent application in the USPTO after March 16, 2013, but before us, could therefore be awarded a patent covering an invention of ours even if we had made the invention before it was made by such third party. This will require us to be cognizant of the time from invention to filing of a patent

Table of Contents

application. Since patent applications in the United States and most other countries are confidential for a period of time after filing or until issuance, we cannot be certain that we or our licensors were the first to either (i) file any patent application related to our product candidates or (ii) invent any of the inventions claimed in our or our licensor’s patents or patent applications. The Leahy-Smith Act also allows third-party submission of prior art to the USPTO during patent prosecution and set forth additional procedures to challenge the validity of a patent by the USPTO administered post grant proceedings, including derivation, reexamination,

inter partes

review, post-grant review and interference proceedings. The USPTO developed additional regulations and procedures to govern administration of the Leahy-Smith Act, and many of the substantive changes to patent law associated with the Leahy-Smith Act, and, in particular, the

first-to-file

provisions, became effective on March 16, 2013. Accordingly, it is not clear what, if any, impact the Leahy-Smith Act will have on the operation of our business. The Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our owned or

in-licensed

patent applications and the enforcement or defense of our issued owned or

in-licensed

patents, all of which could have a material adverse impact on our business prospects and financial condition.

As referenced above, for example, courts in the U.S. continue to refine the heavily

fact-and-circumstance-dependent

jurisprudence defining the scope of patent protection available for therapeutics, narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations. This creates uncertainty about our ability to obtain patents in the future and the value of such patents. In addition, the patent positions of companies in the development and commercialization of pharmaceuticals are particularly uncertain. Recent U.S. Supreme Court rulings have narrowed the scope of patent protection available in certain circumstances and weakened the rights of patent owners in certain situations. This combination of events has created uncertainty with respect to the validity and enforceability of patents, once obtained. Depending on future actions by the U.S. Congress, the federal courts and the USPTO, the laws and regulations governing patents could change in unpredictable ways that could have a material adverse effect on our existing patent portfolio and our ability to protect and enforce our intellectual property in the future. We cannot provide assurance that future developments in U.S. Congress, the federal courts and the USPTO will not adversely impact our owned or

in-licensed

patents or patent applications. The laws and regulations governing patents could change in unpredictable ways that could weaken our and our licensors’ ability to obtain new patents or to enforce our existing owned or

in-licensed

patents and patents that we might obtain or

in-license

in the future. Similarly, changes in patent law and regulations in other countries or jurisdictions or changes in the governmental bodies that enforce them or changes in how the relevant governmental authority enforces patent laws or regulations may have a material adverse effect on our and our licensors’ ability to obtain new patents or to protect and enforce our owned or

in-licensed

patents or patents that we may obtain or

in-license

in the future.

We may be subject to lawsuits or litigation to protect or enforce our patents or other intellectual property, which could result in substantial costs and liability and prevent us from commercializing our potential products.

Third parties may attempt to invalidate our or our licensors’ intellectual property rights via procedures including but not limited to patent infringement lawsuits, declaratory judgment actions, interferences, oppositions and

inter partes

reexamination proceedings before the USPTO, U.S. courts and foreign patent offices or foreign courts. An adverse determination in any such submission or proceeding could reduce the scope or enforceability of, or invalidate, our patent rights, which could adversely affect our competitive position. Because of a lower evidentiary standard in USPTO proceedings compared to the evidentiary standard in United States federal courts necessary to invalidate a patent claim, a third party could potentially provide evidence in a USPTO proceeding sufficient for the USPTO to hold a claim invalid even though the same evidence would be insufficient to invalidate the claim if first presented in a district court action. Accordingly, a third party may attempt to use the USPTO procedures to invalidate our patent claims that would not have been invalidated if first challenged by the third party as a defendant in a district court action. Even if such rights are not directly challenged, disputes could lead to the weakening of our or our licensors’ intellectual property rights. Our defense against any attempt by third parties to circumvent or invalidate our intellectual property rights could be costly to us, could require

Table of Contents

significant time and attention of our management, and could have a material and adverse impact on our profitability, financial condition and prospects or ability to successfully compete.

We or our licensors may find it necessary to pursue claims or to initiate lawsuits to protect or enforce our owned or

in-licensed

patent or other intellectual property rights. The cost to us in defending or initiating any litigation or other proceeding relating to our owned or

in-licensed

patent or other intellectual property rights, even if resolved in our favor, could be substantial, particularly in a foreign jurisdiction, and any litigation or other proceeding would divert our management’s attention. Such litigation or proceedings could materially increase our operating losses and reduce the resources available for development activities or any future sales, marketing or distribution activities. Some of our competitors may be able to more effectively sustain the costs of complex patent litigation because they have substantially greater resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could delay our research and development efforts and materially limit our ability to continue our operations.

If we or our licensors were to initiate legal proceedings against a third party to enforce a patent covering one of our product candidates or our technology, the defendant could counterclaim that such patent is invalid or unenforceable. In patent litigation in the United States, defendant counterclaims alleging invalidity or unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, for example, claiming patent-ineligible subject matter, lack of novelty, indefiniteness, lack of written description,

non-enablement,

anticipation or obviousness. Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld relevant information from the USPTO or made a misleading statement during prosecution. The outcome of such invalidity and unenforceability claims is unpredictable. With respect to the validity question, for example, we cannot be certain that there is no invalidating prior art of which we or our licensors and the patent examiner were unaware during prosecution. If a defendant were to prevail on a legal assertion of invalidity or unenforceability, we could lose at least part, and perhaps all, of the patent protection for one or more of our product candidates or certain aspects of our platform technologies. Such a loss of patent protection could have a material adverse effect on our business, financial condition, results of operations and prospects. Patents and other intellectual property rights also will not protect our product candidates and technologies if competitors or third parties design around such product candidates and technologies without legally infringing, misappropriating or violating our owned or

in-licensed

patents or other intellectual property rights.

We may not be able to protect our intellectual property rights throughout the world, which could negatively impact our business.

Filing, prosecuting and defending patents on current or future technologies or product candidates in all countries throughout the world would be prohibitively expensive, and our intellectual property rights in some countries outside the United States can be less extensive than those in the United States. In addition, the laws of some countries do not protect intellectual property rights to the same extent as laws in the United States. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the United States, or from selling or importing products made using our inventions in and into the United States or other countries. Competitors or other third parties may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export infringing product candidates to territories where we have patent protection or licenses, but enforcement is not as strong as that in the United States. These product candidates may compete with our products, and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

Many companies have encountered significant difficulties in protecting and defending such rights in such jurisdictions. The legal systems of certain countries, including certain developing countries, do not favor the enforcement of patents and other intellectual property protection, particularly those relating to biotechnology, which could make it difficult for us to stop the infringement of any owned and

in-licensed

patents we may obtain in other countries, or the marketing of competing products in violation of our intellectual property and

Table of Contents

proprietary rights generally. Proceedings to enforce our owned or

in-licensed

intellectual property and proprietary rights in foreign jurisdictions could result in substantial costs and could divert our efforts and attention from other aspects of our business. Such proceedings could also put any owned or

in-licensed

patents at risk of being invalidated or interpreted narrowly, could put our owned or

in-licensed

patent applications at risk of not issuing, and could provoke third parties to assert claims against us or our licensors. We or our licensors may not prevail in any lawsuits or other adversarial proceedings that we or our licensors initiate, and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our and our licensors’ efforts to enforce such intellectual property and proprietary rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or

in-license.

Further, many countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, many countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of its patents. If we or any of our licensors are forced to grant a license to third parties with respect to any patents relevant to our business, our competitive position in the relevant jurisdiction may be impaired and our business prospects may be materially adversely affected.

Third parties may initiate legal proceedings alleging that we are infringing, misappropriating or violating their intellectual property rights, the outcome of which would be uncertain and could have a material adverse impact on the success of our business.

Our commercial success depends, in part, upon our ability or the ability of our potential future collaborators to develop, manufacture, market and sell our current or any future product candidates and to use our proprietary technologies without infringing, misappropriating or violating the proprietary and intellectual property rights of third parties. There is a substantial amount of litigation, both within and outside the United States, involving patent and other intellectual property rights in the biotechnology and pharmaceutical industries, including patent infringement lawsuits, interferences, oppositions and

inter partes

review proceedings before the USPTO, U.S. courts, foreign patent offices or foreign courts. As the field of gene and cell therapies advances, patent applications are being processed by national patent offices around the world. There is uncertainty about which patents will issue, and, if they do, there is uncertainty as to when, to whom, and with what claims. Any claims of patent infringement asserted by third parties would be time consuming and could:

•

result in costly litigation that may cause negative publicity;

•

divert the time and attention of our technical personnel and management;

•

cause development delays;

•

prevent us from commercializing any of our product candidates until the asserted patent expires or is held finally invalid or not infringed in a court of law;

•

require us to develop

non-infringing

technology, which may not be possible on a cost-effective basis;

•

subject us to substantial damages for infringement, which we may have to pay if a court decides that the product candidate or technology at issue infringes on or violates the third party’s rights, and, if the court finds that the infringement was willful, we could be ordered to pay treble damages and the patent owner’s attorneys’ fees; or

•

require us to enter into royalty or licensing agreements, which may not be available on commercially reasonable terms, or at all, or which might be

non-exclusive,

which could result in our competitors gaining access to the same technology.

Some of our competitors may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our ability to raise the funds necessary to continue our operations or could otherwise have a material adverse effect on our business, results of operations, financial condition and prospects.

Numerous U.S. and foreign issued patents and pending patent applications, which are owned by third parties, exist in the fields in which we are pursuing development candidates. As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that we may be subject to claims of infringement of the patent rights of third parties. Because patent applications can take many years to issue, there may also be currently pending patent applications that may later result in issued patents that our technology or product candidates may infringe. Further, we cannot guarantee that we are aware of all patents and patent applications potentially relevant to our technology or products. We may not be aware of potentially relevant third-party patents or applications for several reasons. For example, U.S. applications filed before November 29, 2000, and certain U.S. applications filed after that date that will not be filed outside the U.S. remain confidential until a patent issues. Patent applications filed in the United States (after November 29, 2000) and elsewhere are published approximately 18 months after the earliest filing for which priority is claimed, with such earliest filing date being commonly referred to as the priority date. Therefore, patent applications covering our product candidates or platform technologies could have been filed by others without our knowledge. Any such patent application may have priority over our patent applications or patents, which could require us to obtain rights to issued patents covering such technologies. Additionally, claims pending in patent applications that have been published can, subject to certain limitations, be later amended in a manner that could cover our platform, our product candidates or the use of our technologies.

Although no third party has asserted a claim of patent infringement against us as of the date of this proxy statement/prospectus, others may hold proprietary rights that could prevent our product candidates from being marketed. We or our licensors, or any future strategic collaborator, may be party to, or be threatened with, adversarial proceedings or litigation regarding intellectual property rights with respect to our current or any potential future product candidates and technologies, including derivation, reexamination,

inter partes

review or post-grant review before the USPTO and similar proceedings in jurisdictions outside of the United States such as opposition proceedings. In some instances, we may be required to indemnify our licensors for the costs associated with any such adversarial proceedings or litigation. Third parties may assert infringement claims against us, our licensors or our strategic collaborators based on existing patents or patents that may be granted in the future, regardless of their merit. There is a risk that third parties may choose to engage in litigation or other adversarial proceedings with us, our licensors or our strategic collaborators to enforce or otherwise assert their patent rights. Even if we believe such claims are without merit, a court of competent jurisdiction could hold that these third-party patents are not invalid, enforceable and infringed, which could have a material adverse impact on our ability to utilize our platform technologies or to commercialize our current or any future product candidates. In order to successfully challenge the validity of any such U.S. patent in federal court, we would need to overcome a presumption of validity by presenting clear and convincing evidence of invalidity. There is no assurance that a court of competent jurisdiction, even if presented with evidence we believe to be clear and convincing, would invalidate the claims of any such U.S. patent.

Further, we cannot guarantee that we will be able to successfully settle or otherwise resolve such adversarial proceedings or litigation. If we are unable to successfully settle future claims on terms acceptable to us, we may be required to engage in or to continue costly, unpredictable and time-consuming litigation and may be prevented from or experience substantial delays in marketing our product candidates. If we, or our licensors, or any future strategic collaborators are found to infringe, misappropriate or violate a third-party patent or other intellectual property rights, we could be required to pay damages, including treble damages and attorney’s fees, if we are found to have willfully infringed. In addition, we, or our licensors, or any future strategic collaborators may choose to seek, or be required to seek, a license from a third party, which may not be available on commercially reasonable terms, if at all. Even if a license can be obtained on commercially reasonable terms, the rights may be

non-exclusive,

which could give our competitors access to the same technology or intellectual property rights licensed to us, and we could be required to make substantial licensing and royalty payments. Parties making claims against us may obtain injunctive or other equitable relief, which could effectively block our ability to further develop and commercialize our current or future product candidates. We could be forced, including by court order, to cease utilizing, developing, manufacturing and commercializing our platform technologies or product candidates deemed to be infringing. We may be forced to redesign current or future technologies or

Table of Contents

products. Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of employee resources from our business. Any of the foregoing could have a material adverse effect on our ability to generate revenue or achieve profitability and possibly prevent us from generating revenue sufficient to sustain our operations.

Thus, it is possible that one or more third parties will hold patent rights to which we will need a license, which may not be available on reasonable terms or at all. If such third parties refuse to grant us a license to such patent rights on reasonable terms or at all, we may be required to expend significant time and resources to redesign our technology, product candidates or the methods for manufacturing our product candidates, or to develop or license replacement technology, all of which may not be commercially or technically feasible. In such case, we may not be able to market such technology or product candidates and may not be able to perform research and development or other activities covered by these patents. This could have a material adverse effect on our ability to commercialize our product candidates and our business and financial condition.

Lastly, if our technology or products are found to infringe the intellectual property rights of third parties, these third parties may assert infringement claims against our licensees and other parties with whom we have business relationships, and we may be required to indemnify those parties for any damages they suffer as a result of these claims. The claims may require us to initiate or defend protracted and costly litigation on behalf of licensees and other parties regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of those parties or may be required to obtain licenses for the products they use.

Intellectual property litigation may lead to unfavorable publicity that harms our reputation and causes the market price of our common shares to decline.

During the course of any intellectual property litigation, there could be public announcements of the initiation of the litigation as well as results of hearings, rulings on motions and other interim proceedings or developments in the litigation. If securities analysts or investors regard these announcements as negative, the perceived value of our existing product candidates, approved products, programs or intellectual property could be diminished. Accordingly, the market price of shares of our common stock may decline. Such announcements could also harm our reputation or the market for our future products, which could have a material adverse effect on our business.

Intellectual property rights of third parties could adversely affect our ability to commercialize our current or future technologies or product candidates, and we might be required to litigate or obtain licenses from third parties to develop or market our current or future technologies or product candidates, which may not be available on commercially reasonable terms or at all.

Because the gene and cell therapy landscape is still evolving, it is difficult to conclusively assess our freedom to operate without infringing, misappropriating or violating third-party rights. The scope of a patent claim is determined by an interpretation of the law, the written disclosure in a patent and the patent’s prosecution history. Our interpretation of the relevance or the scope of a patent or a pending application may be incorrect. For example, we may incorrectly determine that our products are not covered by a third-party patent or may incorrectly predict whether a third-party’s pending application will issue with claims of relevant scope. Also, our determination of the expiration date of any patent in the United States or abroad that we consider relevant may be incorrect.

There are numerous companies that have pending patent applications and issued patents broadly covering gene and cell therapy generally or covering related inventions that may be relevant for product candidates that we wish to develop. We are aware of third-party patents and patent applications that claim aspects of our current or potential future product candidates and modifications that we may need to apply to our current or potential future product candidates. There are also many issued patents that claim inventions that may be relevant to products we wish to develop. The holders of such patents may be able to block our ability to develop and commercialize the

Table of Contents

applicable product candidate unless we obtain a license or until such patent expires. In either case, such a license may not be available on commercially reasonable terms or at all, or it may be

non-exclusive,

which could result in our competitors gaining access to the same intellectual property.

Our competitive position may materially suffer if patents issued to third parties or other third-party intellectual property rights cover our current or future technologies, product candidates or elements thereof or our manufacture or uses relevant to our development plans. In such cases, we may not be in a position to develop or commercialize current or future technologies, product candidates unless we successfully pursue litigation to narrow or invalidate the third-party intellectual property right concerned, or enter into a license agreement with the intellectual property right holder, if available on commercially reasonable terms. There may be issued patents of which we are not aware, held by third parties that, if found to be valid and enforceable, could be alleged to be infringed by our current or future technologies or product candidates. There also may be pending patent applications of which we are not aware that may result in issued patents, which could be alleged to be infringed by our current or future technologies or product candidates. If such an infringement claim should successfully be brought, we may be required to pay substantial damages or be forced to abandon our current or future technologies or product candidates or to seek a license from any patent holders. No assurances can be given that a license will be available on commercially reasonable terms, if at all.

Third-party intellectual property right holders may also actively bring infringement, misappropriation, or other claims alleging violations of intellectual property rights against us. We cannot guarantee that we will be able to successfully settle or otherwise resolve such claims. If we are unable to successfully settle future claims on terms acceptable to us, we may be required to engage in or to continue costly, unpredictable and time-consuming litigation and may be prevented from or experience substantial delays in marketing our product candidates. If we fail in any such dispute, in addition to being forced to pay damages, we may be temporarily or permanently prohibited from commercializing any of our current or future technologies or product candidates that are held to be infringing, misappropriating or otherwise violating third-party intellectual property rights. We might, if possible, also be forced to redesign current or future technologies or product candidates so that we no longer infringe, misappropriate or violate the third-party intellectual property rights. Any of these events, even if we were ultimately to prevail, could require us to divert substantial financial and management resources that we would otherwise be able to devote to our business, which could have a material adverse effect on our financial condition and results of operations.

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.

In addition to seeking patent protection for certain aspects of our current or future technologies and product candidates, we rely on trade secrets, including confidential and unpatented

know-how,

technology and other proprietary information, to maintain our competitive position and to protect aspects of our business that are not amenable to, or that we do not consider appropriate for, patent protection. Elements of our product candidates, including processes for their preparation and manufacture, may involve proprietary

know-how,

information, or technology that is not covered by patents, and thus for these aspects we may consider trade secrets and

know-how

to be our primary intellectual property. Our trade secrets include, for example, certain program specific synthesis, formulations, patient selection strategies and certain aspects of our research.

Trade secrets and

know-how

can be difficult to protect. We seek to protect trade secrets and confidential and unpatented

know-how,

in part, by entering into

non-disclosure

and confidentiality agreements with parties who have access to such knowledge, such as our employees, corporate collaborators, outside scientific collaborators, contract research organizations, contract manufacturers, consultants, advisors and other third parties. We also enter into confidentiality and invention or patent assignment agreements with our employees and consultants under which they are obligated to maintain confidentiality and to assign their inventions to us. However, we cannot be certain that such agreements have been entered into with all relevant parties, and we cannot be certain that our trade secrets and other confidential proprietary information will not be disclosed or that competitors will

Table of Contents

not otherwise gain access (such as through a cybersecurity breach) to our trade secrets or independently develop substantially equivalent information and techniques. Moreover, individuals with whom we have such agreements may not comply with their terms. Any of these parties may breach such agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for any such breaches. In addition, we take other appropriate precautions, such as physical and technological security measures, to guard against misappropriation of our proprietary technology by third parties.

We may also become involved in inventorship disputes relating to inventions and patents developed by our employees or consultants under such agreements. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret, or securing title to an employee- or consultant-developed invention if a dispute arises, is difficult, expensive and time-consuming, and the outcome is unpredictable. In addition, some courts in the United States and certain foreign jurisdictions disfavor or are unwilling to protect trade secrets. We may need to share our proprietary information, including trade secrets, with future business partners, collaborators, contractors and others located in countries at heightened risk of theft of trade secrets, including through direct intrusion by private parties or foreign actors, and those affiliated with or controlled by state actors. Further, if any of our trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent that competitor from using the technology or information to compete with us. If, in the future, any of our trade secrets were to be disclosed to or independently developed by a competitor, our competitive position would be materially and adversely harmed.

We may be subject to claims that we or our employees or consultants have wrongfully used or disclosed alleged trade secrets or other proprietary information of third parties, including our employees’ or consultants’ former employers or their clients.

We are party to various contracts under which we are obligated to maintain the confidentiality of trade secrets or other confidential and proprietary information of third parties, including our licensors and strategic partners. In addition, many of our employees or consultants and our licensors’ employees or consultants were previously employed at universities or biotechnology or biopharmaceutical companies, including our competitors or potential competitors. We may be subject to claims that one or more of these employees or consultants or we have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of third parties, including former employers of our employees and consultants. Litigation or arbitration may be necessary to defend against these claims. If we fail in defending such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel or may be enjoined from using such intellectual property. Any such proceedings and possible aftermath would likely divert significant resources from our core business, including distracting our technical and management personnel from their normal responsibilities. A loss of key research personnel or their work product could limit our ability to commercialize, or prevent us from commercializing, our current or future technologies or product candidates, which could materially harm our business. Even if we are successful in defending against any such claims, litigation or arbitration could result in substantial costs and could be a distraction to management.

We may be subject to claims challenging the inventorship of our patents and other intellectual property.

We or our licensors may be subject to claims that former employees, collaborators or other third parties have an interest in our owned or

in-licensed

patents as an inventor or

co-inventor,

or in our trade secrets or other intellectual property as a contributor to its development. The failure to name the proper inventors on a patent application can result in the patents issuing thereon being unenforceable. Inventorship disputes may arise from conflicting views regarding the contributions of different individuals named as inventors, the effects of foreign laws where foreign nationals are involved in the development of the subject matter of the patent, conflicting obligations of third parties involved in developing our product candidates or as a result of questions regarding

co-ownership

of potential joint inventions. For example, we or our licensors may have inventorship disputes arise from conflicting obligations of employees, consultants or others who are involved in developing our product candidates. Litigation may be necessary to defend against these and other claims challenging inventorship or our

Table of Contents

or our licensors’ ownership of our owned or

in-licensed

patents, trade secrets or other intellectual property. Alternatively, or additionally, we may enter into agreements to clarify the scope of our rights in such intellectual property. If we or our licensors fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights, such as exclusive ownership of, or right to use, intellectual property that is important to our product candidates. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management and other employees.

Also, our licensors may have relied on third-party consultants or collaborators or on funds from third parties, such as the U.S. government, such that our licensors are not the sole and exclusive owners of the patents we

in-licensed.

If other third parties have ownership rights or other rights to our

in-licensed

patents, they may be able to license such patents to our competitors, and our competitors could market competing products and technology. This could have a material adverse effect on our competitive position, business, financial conditions, results of operations and prospects.

Further, while it is our policy to require our employees and contractors who may be involved in the conception or development of intellectual property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who, in fact, conceives or develops intellectual property that we regard as our own. The assignment of intellectual property rights may not be self-executing, or the assignment agreements may be breached, and we may be forced to bring claims against third parties, or defend claims that they may bring against us, to determine the ownership of what we regard as our intellectual property. Such claims could have a material adverse effect on our business, financial condition, results of operations and prospects.

Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by government patent agencies, and our patent protection could be reduced or eliminated for

non-compliance

with these requirements.

Periodic maintenance fees, renewal fees, annuity fees and various other government fees on patents or applications will be due to be paid to the USPTO and various government patent agencies outside of the United States over the lifetime of our owned and

in-licensed

patents or applications and any patent rights we may own or

in-license

in the future. The USPTO and various

non-U.S.

patent offices require compliance with several procedural, documentary, fee payment and other similar provisions during the patent application process. We employ reputable law firms and other professionals to help us comply with these requirements, and we are also dependent on our licensors to take the necessary action to comply with these requirements with respect to our

in-licensed

intellectual property. In many cases, an inadvertent lapse, including due to the effect of the

COVID-19

on us, our patent counsel or other applicable patent maintenance vendors, can be cured by payment of a late fee or by other means in accordance with the applicable rules. There are situations, however, in which

non-compliance

can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction.

Non-compliance

events that could result in abandonment or lapse of a patent or patent application include, but are not limited to, failure to respond to official actions within prescribed time limits,

non-payment

of fees and failure to properly legalize and submit formal documents. In such an event, potential competitors might be able to enter the market with similar or identical product candidates or platforms, which could have a material adverse effect on our business prospects and financial condition.

If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our business may be adversely affected.

We use and will continue to use registered and/or unregistered trademarks or trade names to brand and market ourselves and our products. Our trademarks or trade names may be challenged, infringed, circumvented, declared generic or determined to be infringing on other marks. We may not be able to protect our rights to these trademarks and trade names or may be forced to stop using these names, which we use for name recognition by

Table of Contents

potential collaborators or customers in our markets of interest. At times, competitors may adopt trade names or trademarks similar to ours, thereby impeding our ability to build brand identity and possibly leading to market confusion. In addition, there could be potential trade name or trademark infringement claims brought by owners of other trademarks or trademarks that incorporate variations of our registered or unregistered trademarks or trade names. Over the long term, if we are unable to establish name recognition based on our trademarks and trade names, we may not be able to compete effectively, and our business may be materially adversely affected.

We may also license our trademarks and trade names to third parties, such as distributors. Though these license agreements may provide guidelines for how our trademarks and trade names may be used, a breach of these agreements or misuse of our trademarks and trade names by our licensees may jeopardize our rights in or diminish the goodwill associated with our trademarks and trade names.

Intellectual property rights do not necessarily address all potential threats to our business.

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations and may not adequately protect our business. The following examples are illustrative:

•

others may be able to create gene circuit technologies that are similar to our technologies or our product candidates, but that are not covered by the claims of any patents that we own, license or control;

•

we or any strategic collaborators might not have been the first to make the inventions covered by the issued patents or pending patent applications that we own, license or control;

•

we or our licensors might not have been the first to file patent applications covering certain of our owned and

in-licensed

inventions;

•

others may independently develop the same, similar, or alternative technologies without infringing, misappropriating or violating our owned or

in-licensed

intellectual property rights;

•

it is possible that our owned or

in-licensed

pending patent applications will not lead to issued patents;

•

issued patents that we own,

in-license,

or control may not provide us with any competitive advantages, or may be narrowed or held invalid or unenforceable, including as a result of legal challenges;

•

our competitors might conduct research and development activities in the United States and other countries that provide a safe harbor from patent infringement claims for certain research and development activities, as well as in countries where we do not have patent rights, and may then use the information learned from such activities to develop competitive products for sale in our major commercial markets;

•

we may choose not to file a patent application in order to maintain certain trade secrets or

know-how,

and a third party may subsequently file a patent application covering such trade secrets or

know-how;

and

•

the patents of others may have an adverse effect on our business.

Should any of these events occur, they could have a material adverse impact on our business and financial condition.

Risks Related to Government Regulation

Clinical development includes a lengthy and expensive process with an uncertain outcome, and results of earlier studies and trials may not be predictive of future trial results.

All of our current product candidates are in preclinical development and their risk of failure is high. It is impossible to predict when or if our candidates or any potential future product candidates will prove effective in

Table of Contents

humans or will receive regulatory approval. Before obtaining marketing approval from regulatory authorities for the sale of any product candidate, we must complete preclinical studies for our current product candidates and then conduct extensive clinical trials to demonstrate the safety, purity and potency, or efficacy of that product candidate in humans. Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during the development process. The results of preclinical studies and clinical trials of any of our current or potential future product candidates may not be predictive of the results of later-stage clinical trials. Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy traits despite having progressed through preclinical studies and initial clinical trials. A number of companies in the pharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or safety profiles, notwithstanding promising results in earlier trials.

We are currently conducting

IND-enabling

studies for our current product candidates. We may experience delays in completing our preclinical studies and initiating or completing our clinical studies. We do not know whether planned preclinical studies and clinical trials will be completed on schedule or at all, or whether planned clinical trials will begin on time, need to be redesigned, enroll patients on time or be completed on schedule, if at all. Our development programs may be delayed for a variety of reasons, including delays related to:

•

the FDA or other regulatory authorities requiring us to submit additional data or imposing other requirements before permitting us to initiate a clinical trial;

•

obtaining regulatory approval to commence a clinical trial;

•

reaching agreement on acceptable terms with prospective CROs and clinical trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and clinical trial sites;

•

obtaining IRB or ethics committee approval at each clinical trial site;

•

recruiting suitable patients to participate in a clinical trial;

•

having patients complete a clinical trial or return for post-treatment

follow-up;

•

clinical trial sites deviating from trial protocol or dropping out of a trial;

•

the FDA placing the clinical trial on hold;

•

subjects failing to enroll or remain in our trial at the rate we expect;

•

subjects choosing an alternative treatment for the indication for which we are developing or other product candidates, or participating in competing clinical trials;

•

lack of adequate funding to continue the clinical trial;

•

subjects experiencing severe or unexpected drug-related adverse events;

•

any changes to our manufacturing process that may be necessary or desired;

•

adding new clinical trial sites;

•

manufacturing sufficient quantities of our product candidates for use in clinical trials.

Furthermore, we expect to rely on our CROs and clinical trial sites to ensure the proper and timely conduct of our clinical trials and, while we expect to enter into agreements governing their committed activities, we have limited influence over their actual performance.

We could encounter delays if prescribing physicians encounter unresolved ethical issues associated with enrolling patients in clinical trials of our current or potential future product candidates in lieu of prescribing existing treatments that have established safety and efficacy profiles. Further, a clinical trial may be suspended or terminated by us, our collaborators, the IRBs of the institutions in which such trials are being conducted, the Data

Table of Contents

Safety Monitoring Board for such trial or by the FDA or other regulatory authorities due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA or other regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a drug or therapeutic biologic, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial.

Moreover, principal investigators for our clinical trials may serve as scientific advisors or consultants to us from time to time and receive cash or equity compensation in connection with such services. If these relationships and any related compensation result in perceived or actual conflicts of interest, or a regulatory authority concludes that the financial relationship may have affected the interpretation of the trial, the integrity of the data generated at the applicable clinical trial site may be questioned and the utility of the clinical trial itself may be jeopardized, which could result in the delay or rejection of the marketing application we submit. Any such delay or rejection could prevent or delay us from commercializing our current or future product candidates.

If we experience delays in the completion of, or termination of, any clinical trial of any of our current or potential future product candidates, the commercial prospects of such product candidate will be harmed, and our ability to generate product revenue from such product candidates will be delayed. In addition, any delays in completing our clinical trials will increase our costs, slow our product development and approval process and jeopardize our ability to commence product sales and generate revenue. Any of these occurrences may have a material adverse effect on our business, financial condition, results of operations and prospects. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our current or potential future product candidates.

We may be unable to obtain U.S. or foreign regulatory approval and, as a result, be unable to commercialize our current or potential future product candidates.

Our current and any potential future product candidates are subject to extensive governmental regulations relating to, among other things, research, testing, development, manufacturing, safety, efficacy, approval, recordkeeping, reporting, labeling, storage, packaging, advertising and promotion, pricing, marketing and distribution of therapeutic biologics. Rigorous preclinical testing and clinical trials and an extensive regulatory approval process are required to be successfully completed in the U.S. and in many foreign jurisdictions before a new drug or therapeutic biologic can be marketed. Satisfaction of these and other regulatory requirements is costly, time-consuming, uncertain and subject to unanticipated delays. It is possible that none of the product candidates we may develop will obtain the regulatory approvals necessary for us or our potential future collaborators to begin selling them.

We have very limited experience in conducting and managing the clinical trials necessary to obtain regulatory approvals, including approval by the FDA and other regulatory authorities. The time required to obtain FDA and other approvals is unpredictable but typically takes many years following the commencement of clinical trials, depending upon the type, complexity and novelty of the product candidate. The standards that the FDA and its foreign counterparts use when regulating us require judgment and can change, which makes it difficult to predict with certainty how they will be applied. Any analysis we perform of data from preclinical and clinical activities is subject to confirmation and interpretation by regulatory authorities, which could delay, limit or prevent regulatory approval. We may also encounter unexpected delays or increased costs due to new government regulations, for example, from future legislation or administrative action, or from changes in regulatory policy during the period of product development, clinical trials and FDA regulatory review in the United States and other jurisdictions. It is impossible to predict whether legislative changes will be enacted, or whether FDA or foreign regulations, guidance or interpretations will be changed, or what the impact of such changes, if any, may be.

Any delay or failure in obtaining required approvals could have a material adverse effect on our ability to generate revenue from the particular product candidate for which we are seeking approval. Further, we and our

Table of Contents

potential future collaborators may never receive approval to market and commercialize any product candidate. Even if we or a potential future collaborator obtains regulatory approval, the approval may be for targets, disease indications or patient populations that are not as broad as we intended or desired or may require labeling that includes significant use or distribution restrictions or safety warnings.

Once a product obtains regulatory approval, numerous post approval requirements apply, including periodic monitoring and reporting obligations, review of promotional material, reports on ongoing clinical trials and adverse events and inspections of manufacturing facilities. In addition, material changes to approved products, including any changes to the manufacturing process or labeling, require further review by the appropriate authorities before marketing. Approvals may also be withdrawn or revoked due to safety, effectiveness or potency concerns, including as a result of adverse events reported in patients or ongoing clinical trials, or failure to comply with cGMP. In addition to revocation or withdrawal of approvals, we and our partners may be subject to warnings, fines, recalls, criminal prosecution or other sanctions if we fail to comply with regulatory requirements. If we or our partners are unable to obtain or maintain regulatory approvals for our products and product candidates, our business, financial position, results of operations and future growth prospects will be negatively impacted and we or our partners may be subject to sanctions. If any of our product candidates prove to be ineffective, unsafe or commercially unviable, we may have to

re-engineer

our current or potential future product candidates, and our entire pipeline could have little, if any, value, which could require us to change our focus and approach to product candidate discovery and therapeutic development, which would have a material adverse effect on our business, financial condition, results of operations and prospects.

We will also be subject to numerous foreign regulatory requirements governing, among other things, the conduct of clinical trials, manufacturing and marketing authorization, pricing and third-party reimbursement. The foreign regulatory approval process varies among countries and may include all of the risks associated with FDA approval described above as well as risks attributable to the satisfaction of local regulations in foreign jurisdictions. Moreover, the time required to obtain approval may differ from that required to obtain FDA approval.

Obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not mean that we will be successful in obtaining regulatory approval of our product candidates in other jurisdictions.

If we succeed in developing any products, we intend to market them in the United States as well as the European Union and other foreign jurisdictions. In order to market and sell our products in other jurisdictions, we must obtain separate marketing approvals and comply with numerous and varying regulatory requirements.

Obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not guarantee that we will be able to obtain or maintain regulatory approval in any other jurisdiction, but a failure or delay in obtaining regulatory approval in one jurisdiction may have a negative effect on the regulatory approval process in others. For example, even if the FDA or EMA grants marketing approval of a product candidate, comparable regulatory authorities in foreign jurisdictions must also approve the manufacturing, marketing and promotion of the product candidate in those countries. Approval procedures vary among jurisdictions and can involve requirements and administrative review periods different from those in the United States, including additional preclinical studies or clinical trials as clinical trials conducted in one jurisdiction may not be accepted by regulatory authorities in other jurisdictions. In many jurisdictions outside the United States, a product candidate must be approved for reimbursement before it can be approved for sale in that jurisdiction. In some cases, the price that we intend to charge for our products is also subject to approval.

Obtaining foreign regulatory approvals and compliance with foreign regulatory requirements could result in significant delays, difficulties and costs for us and could delay or prevent the introduction of our products in certain countries. If we or any partner we work with fail to comply with the regulatory requirements in international markets or fail to receive applicable marketing approvals, our target market will be reduced, and our ability to realize the full market potential of our product candidates will be harmed.

Table of Contents

We may in the future conduct certain of our clinical trials for our product candidates outside of the United States. However, the FDA and other foreign equivalents may not accept data from such trials, in which case our development plans will be delayed, which could materially harm our business.

We may in the future choose to conduct one or more of our clinical trials for our product candidates outside the United States. Although the FDA may accept data from clinical trials conducted outside the United States, acceptance of this data is subject to certain conditions imposed by the FDA. In cases where data from foreign clinical trials are intended to serve as the basis for marketing approval in the United States, the FDA will not approve the application on the basis of foreign data alone unless (i) those data are applicable to the U.S. population and U.S. medical practice; (ii) the studies were performed by clinical investigators of recognized competence; and (iii) the data are considered valid without the need for an

on-site

inspection by the FDA or, if the FDA considers such an inspection to be necessary, the FDA is able to validate the data through an

on-site

inspection or other appropriate means. For studies that are conducted only at sites outside of the United States and not subject to an IND, the FDA requires the clinical trial to have been conducted in accordance with GCPs, and the FDA must be able to validate the data from the clinical trial through an

on-site

inspection if it deems such inspection necessary. For such studies not subject to an IND, the FDA generally does not provide advance comment on the clinical protocols for the studies, and therefore there is an additional potential risk that the FDA could determine that the study design or protocol for a

non-U.S.

clinical trial was inadequate, which could require us to conduct additional clinical trials. There can be no assurance the FDA will accept data from clinical trials conducted outside of the United States. If the FDA does not accept data from our clinical trials of our product candidates, it would likely result in the need for additional clinical trials, which would be costly and time consuming and delay or permanently halt our development of our product candidates.

Many foreign regulatory bodies have similar approval requirements. In addition, such foreign trials would be subject to the applicable local laws of the foreign jurisdictions where the trials are conducted. There can be no assurance that the FDA or any similar foreign regulatory authority will accept data from trials conducted outside of the United States or the applicable jurisdiction. If the FDA or any similar foreign regulatory authority does not accept such data, it would result in the need for additional trials, which would be costly and time-consuming and delay aspects of our business plan, and which may result in our product candidates not receiving approval or clearance for commercialization in the applicable jurisdiction.

Conducting clinical trials outside the United States also exposes us to additional risks, including risks associated with:

•

additional foreign regulatory requirements;

•

foreign exchange fluctuations;

•

compliance with foreign manufacturing, customs, shipment and storage requirements;

•

cultural differences in medical practice and clinical research; and

•

diminished protection of intellectual property in some countries.

Even if we receive regulatory approval for any of our current or potential future product candidates, we will be subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense. Additionally, our current or potential future product candidates, if approved, could be subject to labeling and other restrictions and market withdrawal and we may be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated problems with our products.

Any regulatory approvals that we or potential future collaborators obtain for any of our current or potential future product candidates will be subject to limitations on the approved indicated uses for which a product may be marketed or may be subject to the conditions of approval, or contain requirements for potentially costly post-marketing testing, and surveillance to monitor the safety and efficacy of such product candidate. In addition, if the FDA or any other regulatory authority approves any of our current or potential future product candidates, the

Table of Contents

manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, import, export, advertising, promotion and recordkeeping for such product will be subject to extensive and ongoing regulatory requirements. These requirements include submissions of safety and other post-marketing information and reports, registration, as well as continued compliance with cGMP and good clinical practices for any clinical trials that we conduct post-approval. In addition, manufacturers and manufacturers’ facilities are required to comply with extensive FDA, and comparable foreign regulatory authority requirements, including ensuring that quality control and manufacturing procedures conform to cGMP and cGTP regulations and applicable product tracking and tracing requirements.

Later discovery of previously unknown problems with a product candidate, including adverse events of unanticipated severity or frequency, or with our third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may result in, among other things:

•

restrictions on the marketing or manufacturing of the product candidate, withdrawal of the product candidate from the market or voluntary or mandatory product recalls;

•

fines, warning letters, untitled letters or holds on clinical trials;

•

refusal by the FDA to approve pending applications or supplements to approved applications filed by us or our strategic collaborators;

•

suspension or revocation of product approvals;

•

suspension of any ongoing clinical trials;

•

product seizure or detention or refusal to permit the import or export of products; and

•

injunctions or the imposition of civil or criminal penalties or monetary fines.

The occurrence of any event or penalty described above may inhibit our ability to commercialize our product candidates and generate revenue.

The FDA has the authority to require a risk evaluation and mitigation strategy, or REMS, as part of a BLA or after approval, which may impose further requirements or restrictions on the distribution or use of an approved product, such as limiting prescribing to certain physicians or medical centers that have undergone specialized training, limiting treatment to patients who meet certain

safe-use

criteria and requiring treated patients to enroll in a registry.

Furthermore, the FDA strictly regulates marketing, labeling, advertising and promotion of products that are placed on the market. Products may be promoted only for the approved indications and in accordance with the provisions of the approved label. While physicians may prescribe, in their independent professional medical judgment, products for

off-label

uses as the FDA does not regulate the behavior of physicians in their choice of drug treatments, the FDA does restrict a manufacturer’s communications on the subject of

off-label

use of their products. Companies may only share truthful and not misleading information that is otherwise consistent with a product’s FDA approved labeling. The FDA and other authorities actively enforce the laws and regulations prohibiting the promotion of

off-label

uses and a company that is found to have improperly promoted

off-label

uses may be subject to significant liability including, among other things, adverse publicity, warning letters, corrective advertising and potential civil and criminal penalties. The federal government has levied large civil and criminal fines against companies for alleged improper promotion of

off-label

use and has enjoined companies from engaging in

off-label

promotion. The FDA and other regulatory authorities have also required that companies enter into consent decrees or permanent injunctions under which specified promotional conduct is changed or curtailed.

Occurrence of any of the foregoing could have a material adverse effect on our business and results of operations. The FDA’s and other regulatory authorities’ policies may change, and additional government

Table of Contents

regulations may be enacted that could prevent, limit or delay regulatory approval of our product candidates. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained and we may not achieve or sustain profitability, which would adversely affect our business.

Any product candidates for which we intend to seek approval as biologic products may face competition sooner than anticipated.

The Affordable Care Act includes a subtitle called the Biologics Price Competition and Innovation Act of 2009, or BPCIA, which created an abbreviated approval pathway for biological products that are biosimilar to or interchangeable with an

FDA-licensed

reference biological product. Under the BPCIA, an application for a biosimilar product may not be submitted to the FDA until four years following the date that the reference product was first licensed by the FDA. In addition, the approval of a biosimilar product may not be made effective by the FDA until twelve years from the date on which the reference product was first licensed. During this twelve-year period of exclusivity, another company may still market a competing version of the reference product if the FDA approves a full BLA for the competing product containing the sponsor’s own preclinical data and data from adequate and well-controlled clinical trials to demonstrate the safety, purity and potency of its product. The law is complex. The BPCIA could have a material adverse effect on the future commercial prospects for our biological products.

We believe that any of our future product candidates approved as a biological product under a BLA should qualify for the twelve-year period of exclusivity. However, there is a risk that this exclusivity could be shortened due to Congressional action or otherwise, or that the FDA will not consider our product candidates to be reference products for competing products, potentially creating the opportunity for generic competition sooner than anticipated. Other aspects of the BPCIA, some of which may impact the BPCIA exclusivity provisions, have also been the subject of recent litigation. Moreover, the extent to which a biosimilar, once approved, could be substituted for any one of our reference products in a way that is similar to traditional generic substitution for

non-biological

products will depend on a number of marketplace and regulatory factors that are still developing.

Healthcare legislative reform measures may have a material adverse effect on our business and results of operations.

In the United States, there have been and continue to be a number of legislative initiatives to contain healthcare costs. For example, in March 2010, the Patient Protection and Affordable Care Act, or the ACA, was enacted, which substantially changed the way healthcare is financed by both governmental and private insurers, and significantly impacted the U.S. pharmaceutical industry. Among the provisions of the ACA, of greatest importance to the pharmaceutical and biotechnology industry are the following:

•

an annual, nondeductible fee on any entity that manufactures or imports certain specified branded prescription drugs and biologic agents apportioned among these entities according to their market share in some government healthcare programs;

•

an increase in the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program to 23.1% and 13% of the average manufacturer price for most branded and generic drugs, respectively, and capped the total rebate amount for innovator drugs at 100% of the Average Manufacturer Price, or AMP;

•

a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for certain drugs and biologics that are inhaled, infused, instilled, implanted or injected;

•

extension of manufacturers’ Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid managed care organizations;

Table of Contents

•

expansion of eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to additional individuals and by adding new mandatory eligibility categories for individuals with income at or below 133% of the federal poverty level, thereby potentially increasing manufacturers’ Medicaid rebate liability;

•

a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 50% (and 70% as of January 1, 2019)

point-of-sale

discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D;

•

expansion of the entities eligible for discounts under the Public Health program;

•

a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness research, along with funding for such research;

•

establishment of a Center for Medicare Innovation at CMS to test innovative payment and service delivery models to lower Medicare and Medicaid spending; and

•

implementation of the federal physician payment transparency requirements, sometimes referred to as the “Physician Payments Sunshine Act.”

Since its enactment, there have been judicial, Congressional and executive challenges to certain aspects of the ACA. On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial challenge to the ACA brought by several states without specifically ruling on the constitutionality of the ACA. Prior to the Supreme Court’s decision, President Biden issued an executive order to initiate a special enrollment period from February 15, 2021 through August 15, 2021 for purposes of obtaining health insurance coverage through the ACA marketplace. The executive order also instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the ACA. It is unclear how other healthcare reform measures of the Biden administration or other efforts, if any, to challenge, repeal or replace the ACA will impact our business. In addition, other legislative changes have been proposed and adopted in the United States since the ACA was enacted.

•

On August 2, 2011, the Budget Control Act of 2011 among other things, included aggregate reductions of Medicare payments to providers of 2% per fiscal year. These reductions went into effect on April 1, 2013 and will remain in effect through 2030.

•

On January 2, 2013, the American Taxpayer Relief Act of 2012 among other things, reduced Medicare payments to several providers, including hospitals and increased the statute of limitations period for the government to recover overpayments to providers from three to five years.

•

On April 13, 2017, CMS published a final rule that gives states greater flexibility in setting benchmarks for insurers in the individual and small group marketplaces, which may have the effect of relaxing the essential health benefits required under the ACA for plans sold through such marketplaces.

•

On May 30, 2018, the Right to Try Act, was signed into law. The law, among other things, provides a federal framework for certain patients to access certain investigational new drug products that have completed a Phase 1 clinical trial and that are undergoing investigation for FDA approval. Under certain circumstances, eligible patients can seek treatment without enrolling in clinical trials and without obtaining FDA permission under the FDA expanded access program. There is no obligation for a pharmaceutical manufacturer to make its drug products available to eligible patients as a result of the Right to Try Act.

•

On May 23, 2019, CMS published a final rule to allow Medicare Advantage Plans the option of using step therapy for Part B drugs beginning January 1, 2020.

On December 20, 2019, former President Trump signed into law the Further Consolidated Appropriations Act (H.R. 1865), which repealed the Cadillac tax, the health insurance provider tax, and the medical device excise tax. It is impossible to determine whether similar taxes could be instated in the future.

Additionally, there has been heightened governmental scrutiny recently over the manner in which manufacturers set prices for their marketed products. For example, there have been several recent Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drug products.

At the state level, individual states are increasingly aggressive in passing legislation and implementing regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. In addition, regional health care authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other health care programs. These measures could reduce the ultimate demand for our products, once approved, or put pressure on our product pricing, which could negatively affect our business, financial conditions, and results of operation and prospects.

We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced demand for our current or future product candidates or additional pricing pressures. Further, it is possible that additional governmental action is taken in response to the

COVID-19

pandemic. Any denial in coverage or reduction in reimbursement from Medicare or other government-funded programs may result in a similar denial or reduction in payments from private payors, which may prevent us from being able to generate sufficient revenue, attain profitability or commercialize our products. It is not clear how other future potential changes to the ACA will change the reimbursement model and market outlook for our current and future product candidates.

Failure to comply with health and data protection laws and regulations could lead to government enforcement actions (which could include civil or criminal penalties), private litigation or adverse publicity and could negatively affect our operating results and business.

We may collect, receive, store, process, generate, use, transfer, disclose, make accessible, protect and share personal information, health information and other sensitive information to develop our products, to operate our business, for clinical trial purposes, for legal and marketing purposes, and for other business-related purposes.

We and any potential future collaborators, partners or service providers may be subject to federal, state and foreign data protection laws, regulations and regulatory guidance, the number and scope of which is changing, subject to differing applications and interpretations, and which may be inconsistent among jurisdictions, or in conflict with other rules, laws or contractual obligations. In the United States, numerous federal and state laws and regulations, including federal health information privacy laws, such as the Health Insurance Portability and Accountability Act, or HIPAA, state data breach notification laws, state health information privacy laws and federal and state consumer protection laws, that govern the collection, use, disclosure and protection of health-related and other personal information could apply to our operations or the operations of any future potential collaborators or service providers. In addition, we may obtain health information from third parties (including research institutions from which we obtain clinical trial data) that are subject to privacy and security requirements under HIPAA, or other privacy and data security laws. Depending on the facts and circumstances, we could be subject to civil or criminal penalties if we obtain, use, or disclose individually identifiable health information maintained by a HIPAA-covered entity in a manner that is not authorized or permitted by HIPAA, or if we otherwise violate applicable privacy and data security laws.

International data protection laws, including the EU’s General Data Protection Regulation, or GDPR, may also apply to health-related and other personal information obtained outside of the United States. The GDPR went into effect on May 25, 2018, and imposes stringent data protection requirements for processing of personal data of individuals within the European Economic Area, or EEA, as well as potential fines for noncompliant companies of up to the greater of €20 million or 4% of annual global revenue. The GDPR imposes numerous requirements for the collection, use and disclosure of personal data, including stringent requirements relating to consent and the information that must be shared with data subjects about how their personal information is used, the obligation to notify regulators and affected individuals of personal data breaches, extensive internal privacy governance obligations and obligations to honor expanded rights of individuals in relation to their personal information.

In addition, the GDPR places restrictions on cross-border data transfers. A decision by the Court of Justice of the European Union, or CJEU, in 2020 invalidated the

EU-U.S.

Privacy Shield Framework, which was one of the primary mechanisms used by U.S. companies to import personal information from Europe in compliance with the GDPR’s cross-border data transfer restrictions, and raised questions about whether the European Commission’s Standard Contractual Clauses, or SCCs, one of the primary alternatives to the Privacy Shield, can lawfully be used for personal information transfers from Europe to the United States or most other countries. Similarly, the Swiss Federal Data Protection and Information Commissioner has opined that the

Swiss-U.S.

Privacy Shield is inadequate for transfers of data from Switzerland to the U.S. Furthermore, on June 4, 2021, the European Commission issued new forms of standard contractual clauses for data transfers from controllers or processors in the EEA (or otherwise subject to the GDPR) to controllers or processors established outside the EEA (and not subject to the GDPR). The new forms of standard contractual clauses have replaced the standard contractual clauses that were adopted previously under the Data Protection Directive. We will be required to transition to the new forms of standard contractual clauses and doing so will require significant effort and cost. The new standard contractual clauses may also impact our business as companies based in Europe may be reluctant to utilize the new clauses to legitimize transfers of personal information to third countries given the burdensome requirements of transfer impact assessments and the substantial obligations that the new standard contractual clauses impose upon exporters. If we are investigated by a European data protection authority, we may face fines and other penalties. Any such investigation or charges by European data protection authorities could have a negative effect on our existing business and on our ability to attract and retain new clients or pharmaceutical partners. We may also experience hesitancy, reluctance, or refusal by European or multi-national clients or pharmaceutical partners to continue to use our products due to the potential risk exposure as a result of the current (and, in particular, future) data protection obligations imposed on them by certain data protection authorities in interpretation of current law, including the GDPR. Such clients or pharmaceutical partners may also view any alternative approaches to compliance as being too costly, too burdensome, too legally uncertain, or otherwise objectionable and therefore decide not to do business with us. Any of the foregoing could materially harm our business, prospects, financial condition, and results of operations.

The GDPR has increased our responsibilities and potential liability in relation to personal data processed subject to the GDPR, and we may be required to put in place additional mechanisms to ensure compliance with the GDPR, including as implemented by individual countries. Companies now have to comply with the GDPR and also the United Kingdom GDPR, or UK GDPR, which, together with the amended UK Data Protection Act 2018, retains the GDPR in UK national law. The UK GDPR mirrors the fines under the GDPR, i.e., fines up to the greater of €20 million (£17.5 million) or 4% of global turnover. In addition, on June 28, 2021, the European Commission adopted an adequacy decision in respect of transfers of personal data to the UK for a four-year period (until June 27, 2025). Similarly, the UK has determined that it considers all of the EEA to be adequate for the purposes of data protection. This ensures that data flows between the UK and the EEA remain unaffected. Compliance with the GDPR and applicable laws and regulations relating to privacy and data protection of EEA Member States and the UK is a rigorous and time-intensive process that may increase our cost of doing business or require us to change our business practices, and despite those efforts, there is a risk that we may be subject to fines and penalties, litigation and reputational harm in connection with our European activities. In addition, any failure by us (or our business partners who handle personal data) to comply with GDPR and applicable laws and

Table of Contents

regulations relating to privacy and data protection of EEA Member States and the UK may result in regulators prohibiting our processing of the personal data of EEA data subjects, which could impact our operations and ability to develop our products and provide our services, including interrupting or ending EEA clinical trials.

In addition, states are constantly adopting new laws or amending existing laws, requiring attention to frequently changing regulatory requirements. For example, California enacted the California Consumer Privacy Act, or the CCPA, on June 28, 2018, which took effect on January 1, 2020. The CCPA gives California residents expanded rights to access and delete their personal information, opt out of certain personal information sharing and receive detailed information about how their personal information is used by requiring covered companies to provide new disclosures to California consumers (as that term is broadly defined and can include any of our current or future employees who may be California residents) and provide such residents new ways to

opt-out

of certain sales of personal information. The CCPA provides for civil penalties for violations, as well as a private right of action for data breaches and statutory damages, which is expected to increase data breach class action litigation and result in significant exposure to costly legal judgments and settlements. Although the law includes limited exceptions for health-related information, including clinical trial data, such exceptions may not apply to all of our operations and processing activities. As we expand our operations and trials (both preclinical and clinical), the CCPA may increase our compliance costs and potential liability. Some observers have noted that the CCPA could mark the beginning of a trend toward more stringent privacy legislation in the United States. In November 2020, California passed the California Privacy Rights Act, or the CPRA, which amends and expands the CCPA. The CPRA will impose additional data protection obligations on covered businesses, including additional consumer rights processes, limitations on data uses, new audit requirements for higher risk data, and opt outs for certain uses of sensitive data. It will also create a new California data protection agency authorized to issue substantive regulations and could result in increased privacy and information security enforcement. The majority of the provisions will go into effect on January 1, 2023, and additional compliance investment and potential business process changes may be required. The CPRA has created additional uncertainty and may increase our cost of compliance. Other states are beginning to pass similar laws. In the event that we are subject to or affected by HIPAA, the GDPR, the CCPA, the CPRA or other domestic privacy and data protection laws, any liability from failure to comply with the requirements of these laws could adversely affect our financial condition.

Compliance with U.S. and international data protection laws and regulations could require us to take on more onerous obligations in our contracts, restrict our ability to collect, use and disclose data, or in some cases, impact our ability to operate in certain jurisdictions. Laws and regulations worldwide relating to privacy, data protection and cybersecurity are, and are likely to remain, uncertain for the foreseeable future. While we strive to comply with applicable laws and regulations relating to privacy, data protection and cybersecurity, external and internal privacy and security policies and contractual obligations relating to privacy, data protection and cybersecurity to the extent possible, we may at times fail to do so, or may be perceived to have failed to do so. Moreover, despite our efforts, we may not be successful in achieving compliance if our personnel, collaborators, partners or vendors do not comply with applicable laws and regulations relating to privacy, data protection and cybersecurity, external and internal privacy and security policies and contractual obligations relating to privacy, data protection and cybersecurity. Actual or perceived failure to comply with any laws and regulations relating to privacy, data protection or cybersecurity in the U.S. or foreign jurisdictions could result in government enforcement actions (which could include civil or criminal penalties), private litigation or adverse publicity and could negatively affect our operating results and business. Moreover, clinical trial subjects about whom we or our potential collaborators or service providers obtain information, as well as the providers who share this information with us, may contractually limit our ability to use and disclose the information. Claims that we have violated individuals’ privacy rights, failed to comply with applicable laws or regulations, or breached our contractual obligations, even if we are not found liable, could be expensive and time consuming to defend, result in regulatory actions and proceedings, in addition to private claims and litigation, and could result in adverse publicity that could harm our business.

We also are, or may be asserted to be, subject to the terms of our external and internal privacy and security policies, representations, certifications, publications and frameworks and contractual obligations to third parties

Table of Contents

related to privacy, data protection, information security and processing. Failure to comply or the perceived failure to comply with any of these, or if any of these policies or any of our representations, certifications, publications or frameworks are, in whole or part, found or perceived to be inaccurate, incomplete, deceptive, unfair or misrepresentative of our actual practices, could result in reputational harm; result in litigation; cause a material adverse impact to business operations or financial results and; otherwise result in other material harm to our business.

If we or our existing or potential future collaborators, manufacturers or service providers fail to comply with healthcare laws and regulations, we or they could be subject to enforcement actions, which could affect our ability to develop, market and sell our product candidates and may harm our reputation.

Healthcare providers, physicians and third-party payors, among others, will play a primary role in the prescription and recommendation of any product candidates for which we obtain marketing approval. Our current and future arrangements with third-party payors, providers and customers, among others, may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations that may constrain the business or financial arrangements and relationships through which we market, sell and distribute our product candidates for which we obtain marketing approval. Restrictions under applicable federal and state healthcare laws and regulations in the United States and other countries, include the following:

•

the federal Anti-Kickback Statute, which prohibits, among other things, a person or entity from knowingly and willfully soliciting, offering, paying, receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward either the referral of an individual for, or the purchase, lease order, arranging for or recommendation of, any good, facility, item or service, for which payment may be made, in whole or in part, by a federal healthcare program, such as Medicare or Medicaid. A person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation;

•

federal civil and criminal false claims laws, including the federal False Claims Act, which provides for civil whistleblower or qui tam actions, and civil monetary penalties laws, that impose penalties against individuals or entities for knowingly presenting, or causing to be presented, to the federal government, claims for payment that are false or fraudulent or making a false statement to avoid, decrease or conceal an obligation to pay money to the federal government. In addition, the government may assert that a claim including items and services resulting from a referral made in violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act;

•

HIPAA, which imposes criminal and civil liability for executing a scheme to defraud any healthcare benefit program, or knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false statement in connection with the delivery of or payment for healthcare benefits, items or services. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation;

•

HIPAA, as amended by HITECH, and its implementing regulations, including the Final Omnibus Rule published in January 2013, which impose obligations on certain covered entity healthcare providers, health plans and healthcare clearinghouses as well as their business associates and their subcontractors that perform certain services involving the use or disclosure of individually identifiable health information, including mandatory contractual terms, with respect to safeguarding the privacy, security and transmission of individually identifiable health information, and require notification to affected individuals and regulatory authorities of certain breaches of security of individually identifiable health information. HITECH also created new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorneys’ fees and costs associated with pursuing federal civil actions. In addition, there may be additional federal, state, and

non-U.S.

laws which govern the privacy and security of health and other personal information in certain circumstances, many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts

Table of Contents

•

the federal false statements statute, which prohibits knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false statement in connection with the delivery of or payment for healthcare benefits, items or services;

•

the federal physician payment transparency requirements, sometimes referred to as the “Sunshine Act” under the Affordable Care Act, require certain manufacturers of drugs, devices, biologics and medical supplies that are reimbursable under Medicare, Medicaid, or the Children’s Health Insurance Program to report to the Centers for Medicare & Medicaid Services, or CMS, information related to transfers of value made to physicians (currently defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals, as well as ownership and investment interests of such physicians and their immediate family members. Effective January 1, 2022, these reporting obligations extend to include payments and transfers of value, made during the previous year to certain

non-physician

providers, including physician assistants, nurse practitioners, clinical nurse specialists, certified registered nurse anesthetists, anesthesiologist assistants and certified nurse midwives; and

•

analogous local, state and foreign laws and regulations, such as state anti-kickback and false claims laws that may apply to healthcare items or services reimbursed by third party payors, including private insurers. Local, state and foreign transparency laws that require manufacturers to report information related to payments and transfers of value to other healthcare providers and healthcare entities, marketing expenditures, or drug pricing; state laws that require pharmaceutical companies to register certain employees engaged in marketing activities in the location and comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government; and state and foreign laws governing the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

Ensuring that our future business arrangements with third parties comply with applicable healthcare laws and regulations could involve substantial costs. It is possible that governmental authorities will conclude that our business practices, including our relationships with physicians and other healthcare providers, some of whom are compensated in the form of stock options for consulting services provided, may not comply with current or future statutes, regulations, agency guidance or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any such requirements, we may be subject to penalties, including criminal and significant civil monetary penalties, damages, fines, imprisonment, disgorgement, contractual damages, reputational harm, exclusion from participation in government healthcare programs, integrity obligations, injunctions, recall or seizure of products, total or partial suspension of production, denial or withdrawal of

pre-marketing

product approvals, private qui tam actions brought by individual whistleblowers in the name of the government, refusal to allow us to enter into supply contracts, including government contracts, additional reporting requirements and oversight if subject to a corporate integrity agreement or similar agreement to resolve allegations of

non-compliance

with these laws, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations. Although effective compliance programs can mitigate the risk of investigation and prosecution for violations of these laws, these risks cannot be entirely eliminated. Any action against us for an alleged or suspected violation could cause us to incur significant legal expenses and could divert our management’s attention from the operation of our business, even if our defense is successful. Therefore, even if we are successful in defending against any such actions that may be brought against us, our business may be impaired. If any of the above occur, our ability to operate our business and our results of operations could be adversely affected. In addition, achieving and sustaining compliance with applicable laws and regulations may be costly to us in terms of money, time and resources.

Table of Contents

If we fail to comply with U.S. and foreign regulatory requirements, regulatory authorities could limit or withdraw any marketing or commercialization approvals we may receive and subject us to other penalties that could materially harm our business.

Even if we receive marketing and commercialization approval of a product candidate, we will be subject to continuing regulatory requirements, including in relation to adverse patient experiences with the product and clinical results that are reported after a product is made commercially available, both in the United States and any foreign jurisdiction in which we seek regulatory approval. The FDA and other regulatory authorities have significant post- market authority, including the authority to require labeling changes based on new safety information and to require post-market studies or clinical trials to evaluate safety risks related to the use of a product or to require withdrawal of the product candidate from the market. The FDA and other regulatory authorities also have the authority to require a REMS after approval, which may impose further requirements or restrictions on the distribution or use of an approved drug or therapeutic biologic. The manufacturer and manufacturing facilities we use to make a future product, if any, will also be subject to periodic review and inspection by the FDA and other regulatory authorities, including for continued compliance with cGMP and cGTP requirements. The discovery of any new or previously unknown problems with our third-party manufacturers, manufacturing processes or facilities may result in restrictions on the product candidate, manufacturer or facility, including withdrawal of the product candidate from the market. We intend to rely on third-party manufacturers and we will not have control over compliance with applicable rules and regulations by such manufacturers. Any product promotion and advertising will also be subject to regulatory requirements and continuing regulatory review. If we or our existing or future collaborators, manufacturers or service providers fail to comply with applicable continuing regulatory requirements in the U.S. or foreign jurisdictions in which we seek to market our products, we or they may be subject to, among other things, fines, warning letters, holds on clinical trials, delay of approval or refusal by the FDA or other regulatory authorities to approve pending applications or supplements to approved applications, suspension or withdrawal of regulatory approval, product recalls and seizures, administrative detention of products, refusal to permit the import or export of products, operating restrictions, injunction, civil penalties and criminal prosecution.

In the United States and markets in other countries, patients generally rely on third-party payors to reimburse all or part of the costs associated with their treatment. Adequate coverage and reimbursement from governmental healthcare programs, such as Medicare and Medicaid, and commercial payors is critical to new product acceptance. Further, due to the

COVID-19

pandemic, millions of individuals have lost/will be losing employer-based insurance coverage, which may adversely affect our ability to commercialize our products. It is unclear what effect, if any, the American Rescue Plan will have on the number of covered individuals.

There is also significant uncertainty related to the insurance coverage and reimbursement of newly approved products and coverage may be more limited than the purposes for which the medicine is approved by the FDA or comparable foreign regulatory authorities. In the United States, the principal decisions about reimbursement for new medicines are typically made by the Centers for Medicare & Medicaid Services, or CMS, an agency within the U.S. Department of Health and Human Services. CMS decides whether and to what extent a new medicine will be covered and reimbursed under Medicare and private payors tend to follow CMS to a substantial degree.

Our ability to commercialize any products successfully will depend, in part, on the extent to which coverage and adequate reimbursement for these products and related treatments will be available from third-party payors, such as government authorities, private health insurers and health maintenance organizations. Patients who are prescribed medications for the treatment of their conditions generally rely on third-party payors to reimburse all or part of the costs associated with their prescription drugs. Coverage and adequate reimbursement from government healthcare programs, such as Medicare and Medicaid, and private health insurers are critical to new

Table of Contents

product acceptance. Patients are unlikely to use our future products, if any, unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost. Obtaining coverage and adequate reimbursement for our product candidates may be particularly difficult because of the higher prices often associated with drugs administered under the supervision of a physician. Similarly, because our product candidates are physician-administered, separate reimbursement for the product itself may or may not be available. Instead, the administering physician may or may not be reimbursed for providing the treatment or procedure in which our product is used.

Cost-containment is a priority in the U.S. healthcare industry and elsewhere. As a result, government authorities and other third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications. Increasingly, third-party payors are requiring that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. Third-party payors also may request additional clinical evidence beyond the data required to obtain marketing approval, requiring a company to conduct expensive pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of its product. Commercial third-party payors often rely upon Medicare coverage policy and payment limitations in setting their reimbursement rates, but also have their own methods and approval process apart from Medicare determinations. Therefore, coverage and reimbursement for pharmaceutical products in the U.S. can differ significantly from payor to payor. We cannot be sure that coverage and adequate reimbursement will be available for any product that we commercialize and, if reimbursement is available, that the level of reimbursement will be adequate. Coverage and reimbursement may impact the demand for, or the price of, any product candidate for which we obtain marketing approval. If coverage and reimbursement are not available or are available only at limited levels, we may not be able to successfully commercialize any product candidate for which we obtain marketing approval.

Additionally, the regulations that govern regulatory approvals, pricing and reimbursement for new drugs and therapeutic biologics vary widely from country to country. Some countries require approval of the sale price of a drug or therapeutic biologic before it can be marketed. In many countries, the pricing review period begins after marketing approval is granted. In some foreign markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. As a result, we might obtain regulatory approval for a product in a particular country, but then be subject to price regulations that delay our commercial launch of the product, possibly for lengthy time periods, and negatively impact the revenues we are able to generate from the sale of the product in that country. Adverse pricing limitations may hinder our ability to recoup our investment in one or more product candidates, even if our product candidates obtain regulatory approval.

We are subject to U.S. and foreign anti-corruption and anti-money laundering laws with respect to our operations and

non-compliance

with such laws can subject us to criminal or civil liability and harm our business.

We are subject to the U.S. Foreign Corrupt Practices Act of 1977, as amended, or the FCPA, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, the USA PATRIOT Act, and possibly other state and national anti-bribery and anti-money laundering laws in countries in which we conduct activities. Anti-corruption laws are interpreted broadly and prohibit companies and their employees, agents, third-party intermediaries, joint venture partners and collaborators from authorizing, promising, offering or providing, directly or indirectly, improper payments or benefits to recipients in the public or private sector. We interact with officials and employees of government agencies and government-affiliated hospitals, universities and other organizations. In addition, we may engage third-party intermediaries to promote our clinical research activities abroad or to obtain necessary permits, licenses and other regulatory approvals. We can be held liable for the corrupt or other illegal activities of these third-party intermediaries, our employees, representatives, contractors, collaborators and agents, even if we do not explicitly authorize or have actual knowledge of such activities.

In connection with the Business Combination, New Senti will adopt a Code of Business Conduct and Ethics that will be effective following the closing of the Business Combination and we expect to prepare and implement policies and procedures to ensure compliance with such code. The Code of Business Conduct and Ethics

Table of Contents

mandates compliance with the FCPA and other anti-corruption laws applicable to our business throughout the world. However, we cannot assure you that our employees and third-party intermediaries will comply with this code or such anti-corruption laws. Noncompliance with anti-corruption and anti-money laundering laws could subject us to whistleblower complaints, investigations, sanctions, settlements, prosecution, other enforcement actions, disgorgement of profits, significant fines, damages, other civil and criminal penalties or injunctions, suspension or debarment from contracting with certain persons, the loss of export privileges, reputational harm, adverse media coverage and other collateral consequences. If any subpoenas, investigations or other enforcement actions are launched, or governmental or other sanctions are imposed, or if we do not prevail in any possible civil or criminal litigation, our business, results of operations and financial condition could be materially harmed. In addition, responding to any action will likely result in a materially significant diversion of management’s attention and resources and significant defense and compliance costs and other professional fees. In certain cases, enforcement authorities may even cause us to appoint an independent compliance monitor which can result in added costs and administrative burdens.

General Risk Factors

Disruptions at the FDA and other government agencies caused by funding shortages or global health concerns could hinder their ability to hire, retain or deploy key leadership and other personnel, or otherwise prevent new or modified products from being developed, approved or commercialized in a timely manner or at all, which could negatively impact our business.

The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels, statutory, regulatory and policy changes, the FDA’s ability to hire and retain key personnel and accept the payment of user fees, and other events that may otherwise affect the FDA’s ability to perform routine functions. Average review times at the FDA have fluctuated in recent years as a result. In addition, government funding of other government agencies that fund research and development activities is subject to the political process, which is inherently fluid and unpredictable. Disruptions at the FDA and other agencies may also slow the time necessary for new drugs and biologics or modifications to approved drugs and biologics to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. For example, over the last several years, including for 35 days beginning on December 22, 2018, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA, have had to furlough critical FDA employees and stop critical activities.

Since March 2020 when foreign and domestic inspections of facilities were largely placed on hold, the FDA has been working to resume routine surveillance, bioresearch monitoring and

pre-approval

inspections on a prioritized basis. Since April 2021, the FDA has conducted limited inspections and has employed remote interactive evaluations, using risk management methods, to meet user fee commitments and goal dates. Ongoing travel restrictions and other uncertainties continue to impact oversight operations both domestic and abroad and it is unclear when standard operational levels will resume. The FDA is continuing to complete mission-critical work, prioritize other higher-tiered inspectional needs (e.g.,

for-cause

inspections), and carry out surveillance inspections using risk-based approaches for evaluating public health. Should FDA determine that an inspection is necessary for approval and an inspection cannot be completed during the review cycle due to restrictions on travel, and the FDA does not determine a remote interactive evaluation to be adequate, the agency has stated that it generally intends to issue, depending on the circumstances, a complete response letter or defer action on the application until an inspection can be completed. During the

COVID-19

public health emergency, a number of companies announced receipt of complete response letters due to the FDA’s inability to complete required inspections for their applications. Regulatory authorities outside the U.S. may adopt similar restrictions or other policy measures in response to the ongoing

COVID-19

pandemic and may experience delays in their regulatory activities.

Table of Contents

We or the third parties upon whom we depend may be adversely affected by natural disasters and our business continuity and disaster recovery plans may not adequately protect us from a serious disaster.

Our current operations are located in the San Francisco Bay Area. Any unplanned event, such as earthquake, flood, fire, explosion, extreme weather condition, medical epidemics, including any potential effects from the current global spread of

COVID-19,

power shortage, telecommunication failure or other natural or

man-made

accidents or incidents that result in us being unable to fully utilize our facilities, or the manufacturing facilities of our third-party contract manufacturers, may have a material adverse effect on our ability to operate our business, particularly on a daily basis and have significant negative consequences on our financial and operating conditions. Loss of access to these facilities may result in increased costs, delays in the development of our product candidates or interruption of our business operations. Natural disasters or pandemics such as the

COVID-19

outbreak could further disrupt our operations and have a material adverse effect on our business, financial condition, results of operations and prospects. If a natural disaster, power outage or other event occurred that prevented us from using all or a significant portion of our headquarters, that damaged critical infrastructure, such as our research facilities or the manufacturing facilities of our third-party contract manufacturers, or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible, for us to continue our business for a substantial period of time. The disaster recovery and business continuity plans we have in place may prove inadequate in the event of a serious disaster or similar event. We may incur substantial expenses as a result of the limited nature of our disaster recovery and business continuity plans, which could have a material adverse effect on our business. As part of our risk management policy, we maintain insurance coverage at levels that we believe are appropriate for our business. However, in the event of an accident or incident at these facilities, we cannot assure our investors that the amounts of insurance will be sufficient to satisfy any damages and losses. If our facilities or the manufacturing facilities of our third-party contract manufacturers are unable to operate because of an accident or incident or for any other reason, even for a short period of time, any or all of our research and development programs may be harmed. Any business interruption may have a material adverse effect on our business, financial condition, results of operations and prospects.

Our quarterly operating results may fluctuate significantly or may fall below the expectations of investors or securities analysts, each of which may cause our stock price to fluctuate or decline.

We expect our operating results to be subject to quarterly fluctuations. Our net loss and other operating results will be affected by numerous factors, including:

•

variations in the level of expense related to the ongoing development of our product candidates or future development programs;

•

results of preclinical studies and clinical trials, or the addition or termination of preclinical studies and clinical trials or funding support by us or potential future collaborators;

•

our execution of any collaboration, licensing or similar arrangements, and the timing of payments we may make or receive under potential future arrangements or the termination or modification of any of our existing or potential future collaboration, licensing or similar arrangements;

•

any intellectual property infringement, misappropriation or violation lawsuit or opposition, interference or cancellation proceeding in which we may become involved;

•

additions and departures of key personnel;

•

strategic decisions by us or our competitors, such as acquisitions, divestitures, spin-offs, joint ventures, strategic investments or changes in business strategy;

•

if any of our product candidates receives regulatory approval, the terms of such approval and market acceptance and demand for such product candidates;

•

regulatory developments affecting our product candidates or those of our competitors; and

•

changes in general market and economic conditions.

Table of Contents

If our quarterly operating results fall below the expectations of investors or securities analysts, the price of our common stock could decline substantially. Furthermore, any quarterly fluctuations in our operating results may, in turn, cause the price of our stock to fluctuate substantially. We believe that quarterly comparisons of our financial results are not necessarily meaningful and should not be relied upon as an indication of our future performance.

We may be subject to claims that our employees, consultants, or independent contractors have wrongfully used or disclosed confidential information of third parties.

We have received confidential and proprietary information from third parties. In addition, we employ individuals who were previously employed at other biotechnology or pharmaceutical companies. We may be subject to claims that we or our employees, consultants, or independent contractors have inadvertently or otherwise used or disclosed confidential information of these third parties or our employees’ former employers, or that we caused an employee to breach the terms of his or her

non-competition

non-solicitation

agreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result in substantial cost and be a distraction to our management and employees. If our defenses to these claims fail, in addition to requiring us to pay monetary damages, a court could prohibit us from using technologies or features that are essential to our product candidates, if such technologies or features are found to incorporate or be derived from the trade secrets or other proprietary information of the former employers. Moreover, any such litigation or the threat thereof may adversely affect our reputation, our ability to form strategic alliances or sublicense our rights to collaborators, engage with scientific advisors or hire employees or consultants, each of which would have an adverse effect on our business, results of operations and financial condition. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management.

These broad market and industry factors may seriously harm the market price of New Senti common stock, regardless of New Senti’s operating performance.

New Senti may incur significant costs from class action litigation due to the expected stock volatility.

New Senti’s stock price may fluctuate for many reasons, including as a result of public announcements regarding the progress of development efforts for New Senti’s platform and product candidates, the development efforts of future collaborators or competitors, the addition or departure of key personnel, variations in quarterly operating results and changes in market valuations of biopharmaceutical and biotechnology companies. This risk is especially relevant to New Senti because biopharmaceutical and biotechnology companies have experienced significant stock price volatility in recent years. When the market price of a stock has been volatile as New Senti’s stock price may be, holders of that stock have occasionally brought securities class action litigation against the company that issued the stock. If any New Senti stockholders were to bring a lawsuit of this type against New Senti, even if the lawsuit is without merit, New Senti could incur substantial costs defending the lawsuit. The lawsuit could also divert the time and attention of management.

New Senti will be an “emerging growth company” and it cannot be certain if the reduced disclosure requirements applicable to emerging growth companies will make the New Senti common stock less attractive to investors and may make it more difficult to compare performance with other public companies.

New Senti will be an emerging growth company as defined in the JOBS Act, and it intends to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. Investors may find the New Senti common stock less attractive because New Senti will continue to rely on these exemptions. If some investors find the New Senti common stock less attractive as a result, there may be a less active trading market for their common stock, and the stock price may be more volatile.

An emerging growth company may elect to delay the adoption of new or revised accounting standards. With DYNS making this election, Section 102(b)(2) of the JOBS Act allows New Senti to delay adoption of new or revised accounting standards until those standards apply to

non-public business

entities. As a result, the financial statements contained in this proxy statement/prospectus and those that New Senti will file in the future may not be comparable to companies that comply with public business entities revised accounting standards effective dates.

Future sales and issuances of New Senti common stock or rights to purchase common stock could result in additional dilution of the percentage ownership of New Senti stockholders and could cause the New Senti stock price to fall.

Significant additional capital will be needed in the future to continue New Senti’s planned operations, including further development of New Senti’s gene circuit platform, preparing IND or equivalent filings, conducting preclinical studies and clinical trials, commercialization efforts, expanded research and development activities and costs associated with operating a public company. To raise capital, New Senti may sell common stock, convertible securities or other equity securities in one or more transactions at prices and in a manner as determined from time to time. If New Senti sells common stock, convertible securities or other equity securities, investors may be materially diluted by subsequent sales. Such sales may also result in material dilution to existing stockholders, and new investors could gain rights, preferences and privileges senior to the holders of New Senti common stock.

Pursuant to the Incentive Plan, the New Senti Board or compensation committee is authorized to grant stock options to our employees, directors and consultants. Initially, the aggregate number of shares of New Senti common stock that may be issued pursuant to stock awards under the Incentive Plan is shares. Additionally, the number of shares of New Senti common stock reserved for issuance under the Incentive Plan will automatically increase on January 1 of each year, beginning on January 1, 2023 and continuing through and including January 1, 2032, by 5% of the total number of shares of New Senti Capital Stock outstanding on December 31 of the preceding calendar year, or a lesser number of shares determined by the New Senti Board. Unless the New Senti Board elects not to increase the number of shares available for future grant each year, New Senti stockholders may experience additional dilution, which could cause the New Senti stock price to fall.

New Senti’s issuance of additional shares of common stock or other equity securities of equal or senior rank would have the following effects:

•

DYNS’ existing stockholders’ proportionate ownership interest in New Senti will decrease;

•

the amount of cash available per share, including for payment of dividends in the future, may decrease;

Table of Contents

•

the relative voting strength of each previously outstanding share of common stock may be diminished; and

•

the market price of New Senti’s shares of common stock may decline.

New Senti’s disclosure controls and procedures may not prevent or detect all errors or acts of fraud.

New Senti must design its disclosure controls and procedures to reasonably assure that information we must disclose in reports we file or submit under the Exchange Act is accumulated and communicated to management, and recorded, processed, summarized, and reported within the time periods specified in the rules and forms of the SEC. We believe that any disclosure controls and procedures or internal controls and procedures, no matter how well-conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. For example, our directors or executive officers could inadvertently fail to disclose a new relationship or arrangement causing us to fail to make a required related party transaction disclosure. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by an unauthorized override of the controls. Accordingly, because of the inherent limitations in our control system, misstatements due to error or fraud may occur and not be detected.

Reports published by analysts, including projections in those reports that differ from New Senti’s actual results, could adversely affect the price and trading volume of New Senti common stock.

DYNS currently expects that securities research analysts will establish and publish their own periodic projections for the business of New Senti. These projections may vary widely and may not accurately predict the results New Senti actually achieves. New Senti’s stock price may decline if its actual results do not match the projections of these securities research analysts. Similarly, if one or more of the analysts who write reports on New Senti downgrades its stock or publishes inaccurate or unfavorable research about its business, New Senti’s stock price could decline. If one or more of these analysts ceases coverage of New Senti or fails to publish reports on New Senti regularly, its stock price or trading volume could decline. While DYNS expects research analyst coverage following the Business Combination, if no analysts commence coverage of New Senti, the trading price and volume for New Senti common stock could be adversely affected.

New Senti’s actual financial position and results of operations may differ materially from the unaudited pro forma condensed combined financial information included in this proxy statement/prospectus, which may not be indicative of what New Senti’s actual financial position or results of operations would have been.

The unaudited pro forma condensed combined financial information in this proxy statement/prospectus is presented for illustrative purposes only and is not necessarily indicative of what New Senti’s actual financial position or results of operations would have been had the Business Combination been completed on the dates indicated. See the section titled “

Unaudited Pro Forma Condensed Combined Financial Information

” for more information.

The obligations associated with being a public company will involve significant expenses and will require significant resources and management attention, which may divert from New Senti’s business operations.

As a public company, New Senti will become subject to the reporting requirements of the Exchange Act and the Sarbanes-Oxley Act. The Exchange Act requires the filing of annual, quarterly and current reports with respect to a public company’s business and financial condition. The Sarbanes-Oxley Act requires, among other things, that a public company establish and maintain effective internal control over financial reporting. As a result, New Senti will incur significant legal, accounting and other expenses that Senti did not previously incur. New Senti’s entire management team and many of its other employees will need to devote substantial time to compliance, and may not effectively or efficiently manage its transition into a public company.

Table of Contents

These rules and regulations will result in New Senti incurring substantial legal and financial compliance costs and will make some activities more time-consuming and costly. For example, these rules and regulations will likely make it more difficult and more expensive for New Senti to obtain director and officer liability insurance, and it may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be difficult for New Senti to attract and retain qualified people to serve on its board of directors, its board committees or as executive officers.

Provisions in New Senti’s amended and restated certificate of incorporation, New Senti’s amended and restated bylaws and Delaware law may have anti-takeover effects that could discourage an acquisition of New Senti by others, even if an acquisition would be beneficial to our stockholders, and may prevent attempts by our stockholders to replace or remove our current management, which could depress the trading price of new Senti’s common stock.

New Senti’s amended and restated certificate of incorporation, amended and restated bylaws and Delaware law contain provisions that may have the effect of discouraging, delaying or preventing a change in control of us or changes in our management that stockholders may consider favorable, including transactions in which you might otherwise receive a premium for your shares. New Senti’s amended and restated certificate of incorporation and amended and restated bylaws include provisions that:

•

authorize “blank check” preferred stock, which could be issued by our board of directors without stockholder approval and may contain voting, liquidation, dividend and other rights superior to our common stock;

•

create a classified board of directors whose members serve staggered three-year terms;

•

specify that special meetings of our stockholders can be called only by our board of directors;

•

prohibit stockholder action by written consent;

•

establish an advance notice procedure for stockholder approvals to be brought before an annual meeting of our stockholders, including proposed nominations of persons for election to our board of directors;

•

specify that no stockholder is permitted to cumulate votes at any election of directors;

•

expressly authorize our board of directors to make, alter, amend or repeal our amended and restated bylaws; and

•

require supermajority votes of the holders of our common stock to amend specified provisions of our amended and restated certificate of incorporation and amended and restated bylaws.

These provisions, alone or together, could delay or prevent hostile takeovers and changes in control or changes in our management. These provisions could also limit the price that investors might be willing to pay in the future for shares of New Senti’s common stock, thereby depressing the market price of New Senti’s common stock.

In addition, because we are incorporated in the State of Delaware, we are governed by the provisions of Section 203 of the General Corporation Law of the State of Delaware, which prohibits a person who owns in excess of 15% of our outstanding voting stock from merging or combining with us for a period of three years after the date of the transaction in which the person acquired in excess of 15% of our outstanding voting stock, unless the merger or combination is approved in a prescribed manner.

Any provision of New Senti’s amended and restated certificate of incorporation, amended and restated bylaws or Delaware law that has the effect of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of New Senti’s common stock, and could also affect the price that some investors are willing to pay for New Senti’s common stock.

Table of Contents

New Senti’s amended and restated bylaws designate the Court of Chancery of the State of Delaware as the exclusive forum for certain state law litigation that may be initiated by our stockholders and the U.S. federal district courts as the exclusive forum for certain securities law actions, which could limit our stockholders’ ability to litigate disputes with us in a different judicial forum and increase the costs for our stockholders to pursue certain claims against us.

Pursuant to New Senti’s amended and restated bylaws, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for the following types of actions or proceedings under Delaware statutory or common law: (i) any derivative action or proceeding brought on our behalf; (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our current or former directors, officers or employees to us or our stockholders; (iii) any action asserting a claim arising pursuant to any provision of the General Corporation Law of the State of Delaware, our amended and restated certificate of incorporation or our amended and restated bylaws (including their interpretation, validity or enforceability); or (iv) any action asserting a claim governed by the internal affairs doctrine. This exclusive forum provision will not apply to any causes of action arising under the Securities Act or the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. Unless we consent in writing to the selection of an alternate forum, the United States federal district courts shall be the sole and exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. In addition, our amended and restated bylaws provide that any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock is deemed to have notice of and consented to these exclusive forum provisions. The forum selection provisions in our amended and restated bylaws may limit our stockholders’ ability to litigate disputes with us in a judicial forum that they find favorable for disputes with us or our directors, officers or employees, which may discourage the filing of lawsuits against us and our directors, officers and employees, even though an action, if successful, might benefit our stockholders. In addition, these forum selection provisions may impose additional litigation costs for stockholders who determine to pursue any such lawsuits against us.

Risks Related to the Business Combination and Redemptions

DYNS will incur significant transaction and transition costs in connection with the Business Combination.

DYNS has incurred and is expect to incur significant, non-recurring costs in connection with consummating the Business Combination and operating as a public company following the consummation of the Business Combination. DYNS may also incur additional costs to retain key employees. Certain transaction expenses incurred in connection with the Business Combination, including all legal, accounting, consulting, investment banking and other fees, expenses and costs, will be paid by New Senti following the closing of the Business Combination.

The Business Combination Agreement provides that all of the representations, warranties and covenants of the parties contained therein shall not survive the Closing, except for those covenants that by their terms apply or are to be performed in whole or in part after the Closing, and then only with respect to breaches occurring after Closing. Accordingly, there are no remedies available to the parties with respect to any breach of the representations, warranties, covenants or agreements of the parties to the Business Combination Agreement after the Closing of the Business Combination, except for covenants to be performed in whole or in part after the Closing. As a result, DYNS will have no remedy available to it if the Business Combination is consummated and it is later revealed that there was a breach of any of the representations, warranties and covenants made by Senti at the time of the Business Combination.

Table of Contents

Although DYNS has conducted due diligence on Senti, DYNS cannot assure you that this diligence revealed all material issues that may be present in Senti’s business, that it would be possible to uncover all material issues through a customary amount of due diligence, or that factors outside of DYNS’s and Senti’s control will not later arise. As a result, after the Closing, New Senti may be forced to later write-down or write-off assets, restructure

its operations, or incur impairment or other charges that could result in losses. Even if DYNS’s due diligence successfully identifies certain risks, unexpected risks may arise and previously known risks may materialize in a manner not consistent with DYNS’s preliminary risk analysis. Even though these charges may be non-cash items and may not have an immediate impact on New Senti’s liquidity, the fact that New Senti may charges of this nature could contribute to negative market perceptions about the Combined Company’s securities. In addition, charges of this nature may cause New Senti to be unable to obtain future financing on favorable terms or at all. Accordingly, any DYNS stockholder who chooses to remain a stockholder of the Combined Company following the Business Combination could suffer a reduction in the value of their shares. Such stockholders are unlikely to have a remedy for such reduction in value unless they are able to successfully claim that the reduction was due to the breach by DYNS’s officers or directors of a duty of care or other fiduciary duty owed to them, or if they are able to successfully bring a private claim under securities laws that the proxy solicitation relating to the Business Combination contained an actionable material misstatement or material omission.

The Sponsor and DYNS’s officers and directors and/or their affiliates beneficially own or have a pecuniary interest in Founder Shares and additional securities that they purchased in the Concurrent Private Placement. The holders have no redemption rights with respect to these securities in the event a business combination is not effected in the required time period. Therefore, if the Business Combination with Senti or another business combination is not approved within the required time period, such securities held by such persons will be worthless. Such securities had an aggregate market value of $ million based upon the closing prices of the Class A Common Stock on Nasdaq on the Record Date. Furthermore, the Sponsor and DYNS’s officers and directors and their affiliates are entitled to reimbursement of out-of-pocket expenses incurred by them in connection with certain activities on DYNS’s behalf, such as identifying and investigating possible business targets and business combinations. Any such expenses will be repaid upon completion of the Business Combination with Senti. As of , no such reimbursable expenses have been incurred. If any such expenses are incurred, however, if DYNS fails to consummate the Business Combination, they will not have any claim against the Trust Account for repayment or reimbursement. Accordingly, DYNS may not be able to repay or reimburse these amounts if the Business Combination is not completed. See the section entitled “

Proposal 1: The Business Combination Proposal—Interests of the Sponsor and DYNS’s Directors and Officers in the Business Combination.

”

These financial interests may have influenced the decision of DYNS’s directors to approve the Business Combination with Senti and to continue to pursue such Business Combination. In considering the recommendations of DYNS’s Board to vote for the Business Combination Proposal and other proposals, DYNS’s stockholders should consider these interests.

The Public Stockholders will experience immediate dilution as a consequence of the issuance of Class A Common Stock as consideration in the Business Combination and in the PIPE Investment.

In accordance with the terms and subject to the conditions of the Business Combination Agreement, at the Effective Time, (i) each outstanding share of Senti common stock will be cancelled and converted into the right to receive a number of shares of Class A Common Stock equal to the Exchange Ratio (rounded down to the nearest whole share); (ii) each outstanding share of Senti preferred stock will be cancelled and converted into the

Table of Contents

right to receive a number of shares of Class A Common Stock equal to (A) the aggregate number of shares of Senti common stock that would be issued upon conversion of the shares of Senti preferred stock based on the applicable conversion ratio immediately prior to the Effective Time, multiplied by (B) the Exchange Ratio (rounded down to the nearest whole share); and (iii) each outstanding Senti option will be converted into an option to purchase a number of shares of Class A Common Stock (rounded down to the nearest whole share) equal to (A) the number of shares of Senti common stock subject to such option multiplied by (B) the Exchange Ratio, at an exercise price per share equal to the current exercise price per share for such option divided by the Exchange Ratio (rounded up to the nearest whole cent). In addition, holders of shares of Senti common stock and Senti preferred stock also will be eligible to receive Contingent Consideration of up to an aggregate of 2,000,000 shares of Class A Common Stock based on the share price performance of the Class A Common Stock or upon a change in control. Finally, in connection with the PIPE Investment, an aggregate of 6,680,000 shares of Class A Common Stock will be issued. The issuance of additional Class A Common Stock will significantly dilute the equity interests of existing holders of DYNS securities, and may adversely affect prevailing market prices for the Class A Common Stock.

The exercise of DYNS’s directors’ and officers’ discretion in agreeing to changes or waivers in the terms of the Business Combination Agreement may result in a conflict of interest when determining whether such changes to the terms of the Business Combination Agreement or waivers of conditions are appropriate and in the best interests of DYNS’s stockholders.

In the period leading up to the Closing, events may occur that, pursuant to the Business Combination Agreement, would require DYNS to agree to amend the Business Combination Agreement, to consent to certain actions taken by Senti or to waive rights that DYNS is entitled to under the Business Combination Agreement. Such events could arise because of changes in the course of Senti’s business, a request by Senti to undertake actions that would otherwise be prohibited by the terms of the Business Combination Agreement or the occurrence of other events that would have a material adverse effect on Senti’s business and would entitle DYNS to terminate the Business Combination Agreement. In any of such circumstances, it would be at DYNS’s discretion, acting through its Board, to grant its consent or waive those rights. The existence of the financial and personal interests of the directors described in the preceding risk factors may result in a conflict of interest on the part of one or more of the directors between what he, she or they may believe is best for DYNS and what he, she or they may believe is best for himself, herself or themselves in determining whether or not to take the requested action. As of the date of this proxy statement/prospectus, DYNS does not believe there will be any material changes or waivers that DYNS’s directors and officers would be likely to make after the mailing of this proxy statement/prospectus. DYNS will circulate a supplemental or amended proxy statement/prospectus if changes to the terms of the Business Combination that would have a material impact on its stockholders are required prior to the vote on the Business Combination Proposal.

Under the terms of the Current Charter, DYNS must complete the Business Combination with Senti or another business combination by May 28, 2023 (or such later date as may be approved by DYNS stockholders in an amendment to its Current Charter), or DYNS must cease all operations except for the purpose of winding up, redeeming 100% of the outstanding Public Shares for cash and, subject to the approval of its remaining stockholders and its Board, dissolving and liquidating. In such event, third parties may bring claims against DYNS. Although DYNS seeks waiver agreements from certain vendors and service providers it has engaged and owes money to, and the prospective target businesses it has negotiated with, whereby such parties will waive any right, title, interest or claim of any kind they may have in or to any monies held in the Trust Account, there is no

Table of Contents

guarantee that vendors, regardless of whether they execute such waivers, will not seek recourse against the Trust Account notwithstanding such agreements. Furthermore, there is no guarantee that a court will uphold the validity of such agreements. Accordingly, the proceeds held in the Trust Account could be subject to claims which could take priority over those of the Public Stockholders. If DYNS is unable to complete a business combination within the required time period, the Sponsor has agreed that it will be liable under certain circumstances described herein to ensure that the proceeds in the Trust Account are not reduced by the claims of target businesses or claims of vendors or other entities that are owed money by DYNS for services rendered or contracted for or products sold to DYNS. However, the Sponsor may not be able to meet such obligation as its only assets are securities of DYNS. Therefore, the per-share distribution from the Trust Account in such a situation may be less than $10.00 due to such claims.

Additionally, if DYNS is forced to file a bankruptcy case or an involuntary bankruptcy case is filed against it which is not dismissed, or if DYNS otherwise enters compulsory or court supervised liquidation, the proceeds held in the Trust Account could be subject to applicable bankruptcy law, and may be included in its bankruptcy estate and subject to the claims of third parties with priority over the claims of DYNS’s stockholders. To the extent any bankruptcy claims deplete the Trust Account, DYNS may not be able to return to its Public Stockholders at least $10.00 per share of DYNS Common Stock.

DYNS’s stockholders may be held liable for claims by third parties against DYNS to the extent of distributions received by them.

If DYNS is unable to complete the Business Combination with Senti or another business combination within the required time period, DYNS will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to us to pay our taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public Stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and our Board, dissolve and liquidate, subject in the case of clauses (ii) and (iii) above to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. DYNS cannot assure you that it will properly assess all claims that may potentially be brought against DYNS. As such, DYNS’s stockholders could potentially be liable for any claims to the extent of distributions received by them (but no more) and any liability of its stockholders may extend well beyond the third anniversary of the date of distribution. Accordingly, DYNS cannot assure you that third parties will not seek to recover from its stockholders amounts owed to them by DYNS.

If DYNS file a bankruptcy petition or an involuntary bankruptcy petition is filed against DYNS that is not dismissed, the proceeds held in the Trust Account could be subject to applicable bankruptcy law, and may be included in our bankruptcy estate and subject to the claims of third parties with priority over the claims of our stockholders. To the extent any bankruptcy claims deplete the Trust Account, DYNS cannot provide any assurance that DYNS will be able to return $10.00 per share to our Public Stockholders. Additionally, if DYNS file a bankruptcy petition or an involuntary bankruptcy petition is filed against DYNS that is not dismissed, any distributions received by stockholders could be viewed under applicable debtor/creditor and/or bankruptcy laws as either a “preferential transfer” or a “fraudulent conveyance.” As a result, a bankruptcy court could seek to recover some or all amounts received by DYNS’s stockholders. Furthermore, DYNS’s Board may be viewed as having breached its fiduciary duty to DYNS‘s creditors and/or may have acted in bad faith, thereby exposing itself and our company to claims of punitive damages, by paying Public Stockholders from the Trust Account prior to addressing the claims of creditors. DYNS cannot provide any assurance that claims will not be brought against DYNS for these reasons.

Activities taken by existing DYNS stockholders to increase the likelihood of approval of the Business Combination Proposal and the other Proposals could have a depressive effect on DYNS Common Stock.

At any time prior to the Special Meeting, during a period when they are not then aware of any material nonpublic information regarding DYNS or its securities, the Sponsor, DYNS’s officers, directors and stockholders from prior to the Initial Public Offering, Senti or Senti’s stockholders and/or their respective affiliates may enter into transactions with such investors and others to provide them with incentives to acquire DYNS Common Stock or vote their shares in favor of the Business Combination Proposal. The purpose of such transactions would be to increase the likelihood of satisfaction of the requirements to consummate the Business Combination where it appears that such requirements would otherwise not be met. Entering into any such arrangements may have a depressive effect on DYNS Common Stock. For example, as a result of these arrangements, an investor or holder may have the ability to effectively purchase shares at a price lower than market and may therefore be more likely to sell the shares he, she or it owns, either prior to or immediately after the Special Meeting.

If the Adjournment Proposal is not approved, and an insufficient number of votes have been obtained to authorize the consummation of the Business Combination, the Board will not have the ability to adjourn the Special Meeting to a later date in order to solicit further votes, and, therefore, the Business Combination will not be approved.

Neither the Board nor any committee thereof obtained a third-party financial opinion in determining whether or not to pursue the Business Combination.

Neither the board of directors of DYNS nor any committee thereof obtained an opinion from an independent investment banking or accounting firm that the price that DYNS is paying for Senti is fair to DYNS from a financial point of view. Neither the board of directors of DYNS nor any committee thereof obtained a third-party valuation in connection with the business combination. In analyzing the business combination, the board of directors of DYNS and management conducted due diligence on Senti and researched the industry in which Senti operates. The board of directors of DYNS reviewed, among other things, financial due diligence materials prepared by Senti, including, financial and market data information on selected comparable companies, the implied purchase price multiple of Senti and the financial terms set forth in the Business Combination Agreement, and concluded that the Business Combination was in the best interest of its stockholders. Accordingly, investors will be relying solely on the judgment of the board of directors and management of DYNS in valuing Senti, and the board of directors and management of DYNS may not have properly valued such businesses. The lack of a third-party valuation may also lead an increased number of shareholders to vote against the business combination or demand redemption of their shares, which could potentially impact our ability to consummate the business combination.

We are dependent upon our current executive officers and directors and their loss could adversely affect our ability to operate.

Our operations are dependent upon a relatively small group of individuals and, in particular, our executive officers and directors. We believe that our success depends on the continued service of our officers and directors, at least until we have completed the Business Combination.

Certain of our existing stockholders have agreed to vote in favor of the Business Combination, regardless of how our Public Stockholders vote.

Certain of our existing shareholdres, including the Sponsor and our directors and officers, have agreed to vote the Founder Shares, as well as any Public Shares purchased during or after the IPO, in favor of the Business Combination.

Table of Contents

At the time of the general meeting, we expect that the Sponsor and our directors and officers will collectively own approximately % of the outstanding DYNS Common Stock. Accordingly, it is more likely that the necessary stockholder approval will be received than would be the case if such persons agreed to vote their shares in accordance with the majority of the votes cas by our Public Stockholders.

Our actual financial position and results of operations may differ materially from the unaudited pro forma financial information included in this proxy statement/prospectus.

The unaudited pro forma condensed combined financial information in this proxy statement/prospectus is presented for illustrative purposes only and is not necessarily indicative of what our actual financial position or results of operations would have been had the Business Combination been completed on the dates incidated. See “Unaudited Pro Forma Condensed Combined Financial Information” for more information.

We do not have a specified maximum redemption threshold. The absence of such a redemption threshold may make it possible for us to complete the Business Combination with which a substantial majority of our stockholders do not agree.

Our amended and restated certificate of incorporation does not provide a specified maximum redemption threshold, except that in no event will we redeem our Public Shares in an amount that would cause our net tangible assets, after payment of the deferred underwriting commissions, to be less than $5,000,001 upon completion of our initial business combination (such that we do not then become subject to the SEC’s “penny stock” rules), or any greater net tangible asset or cash requirement that may be contained in the agreement relating to our initial business combination. As a result, we may be able to complete our initial business combination even though a substantial majority of our public stockholders do not agree with the transaction and have redeemed their shares or have entered into privately negotiated agreements to sell their shares to the Sponsor, our officers and directors, advisors or any of their affiliates. In the event the aggregate cash consideration we would be required to pay for all Class A Common Stock that are validly submitted for redemption plus any amount required to satisfy cash conditions pursuant to the terms of the proposed initial business combination exceed the aggregate amount of cash available to us, we will not complete the initial business combination or redeem any shares, all Class A Common Stock submitted for redemption will be returned to the holders thereof, and we instead may search for an alternate business combination.

If the Business Combination’s benefits do not meet the expectations of investors, stockholders or financial analysts, the market price of our Class A Common Stock may decline.

If the benefits of the Business Combination do not meet the expectations of investors or securities analysts, the market price of our Class A Common Stock prior to the Closing may decline. The market value of our Class A Common Stock at the time of the Business Combination may vary significantly from its price on the date the Business Combination Agreement was executed, the date of this proxy statement/prospectus, or the date on which our stockholders vote on the Business Combination.

In addition, following the Business Combination, fluctuations in the price of our Class A Common Stock could contribute to the loss of all or part of your investment. Any of the factors listed below could have a material adverse effect on your investment in our Class A Common Stock and our Class A Common Stock may trade at a price significantly below the price you paid for it. In such circumstances, the trading price of our Class A Common Stock may not recover and may experience a further decline.

Factors affecting the trading price of our Class A Common Stock following the Business Combination may include:

•

actual or anticipated fluctuations in our quarterly financial results or the quarterly financial results of companies perceived to be similar to us;

•

changes in the market’s expectations about our operating results;

Table of Contents

•

success of competitors;

•

our operating results failing to meet the expectation of securities analysts or investors in a particular period;

•

changes in financial estimates and recommendations by securities analysts concerning New Senti or the market in general;

•

operating and stock price performance of other companies that investors deem comparable to New Senti;

•

changes in laws and regulations affecting our business;

•

commencement of, or involvement in, litigation involving New Senti;

•

changes in our capital structure, such as future issuances of securities or the incurrence of additional debt;

•

the volume of shares available for public sale;

•

any major change in our board of directors or management;

•

sales of substantial amounts of securities by our directors, executive officers or significant stockholders or the perception that such sales could occur;

•

general economic and political conditions such as recessions, interest rates, fuel prices, international currency fluctuations and acts of war or terrorism; and

•

other developments affecting the biotechnology industry.

Broad market and industry factors may materially harm the market price of our Class A Common Stock irrespective of our operating performance. The stock market in general and Nasdaq have experienced price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of the particular companies affected. The trading prices and valuations of these stocks, and of our securities, may not be predictable. A loss of investor confidence in the market for retail stocks or the stocks of other companies, notably in the biotechnology industry, which investors perceive to be similar to New Senti could depress our stock price regardless of our business, prospects, financial conditions or results of operations. A decline in the market price for our Class A Common Stock also could adversely affect our ability to issue additional securities and our ability to obtain additional financing in the future.

We are currently an emerging growth company within the meaning of the Securities Act, and if we take advantage of certain exemptions from disclosure requirements available to emerging growth companies, this could make our securities less attractive to investors and may make it more difficult to compare our performance with other public companies.

We are currently an emerging growth company within the meaning of the Securities Act, as modified by the JOBS Act, and we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. As a result, our shareholders may not have access to certain information they may deem important. We could remain an emerging growth company for up to five years from the date of our IPO, although circumstances could cause us to lose that status earlier, including if the market value of our Class A Common Stock held by non-affiliates exceeds $700,000,000 as of any June 30 before that time, in which case we would no longer be an emerging growth company as of the following December 31. We cannot predict whether investors will find our securities less attractive because we will rely on these exemptions. If some investors find our securities less attractive as a result of our reliance on these exemptions, the trading prices of our securities may be lower than they otherwise would be, there may be a less active trading market for our securities and the trading prices of our securities may be more volatile.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. We have elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, we, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of our financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accountant standards used.

Our directors may decide not to enforce the indemnification obligations of the Sponsor, resulting in a reduction in the amount of funds in the Trust Account available for distribution to our Public Stockholders.

The Sponsor has agreed that it will be liable to us if and to the extent any claims by a third party for services rendered or products sold to us, or a prospective target business with which we have entered into a written letter of intent, confidentiality or other similar agreement or business combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per public share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per public share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the funds held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under our indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act. However, we have not asked the Sponsor to reserve for such indemnification obligations, nor have we independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and believe that the Sponsor’s only assets are securities of our company. Therefore, we cannot provide any assurance that the Sponsor would be able to satisfy those obligations. None of our officers or directors will indemnify us for claims by third parties including, without limitation, claims by vendors and prospective target businesses.

If the Sponsor asserts that it is unable to satisfy its indemnification obligations or that it has no indemnification obligations related to a particular claim, our independent directors would determine whether to take legal action against the Sponsor to enforce its indemnification obligations. While we currently expect that our independent directors would take legal action on our behalf against the Sponsor to enforce its indemnification obligations to us, it is possible that our independent directors, in exercising their business judgment, may choose not to do so if, for example, the cost of such legal action is deemed by the independent directors to be too high relative to the amount recoverable or if the independent directors determine that a favorable outcome is not likely. We have not asked the Sponsor to reserve for such indemnification obligations and we cannot provide any assurance that the Sponsor would be able to satisfy those obligations. Accordingly, we cannot provide any assurance that due to claims of creditors the actual value of the per-share redemption price will not be less than $10.00 per Public Share.

In connection with the recent restatement of our financial statements, our management has concluded that our disclosure controls and procedures were not effective as of September 30, 2021 due to a material weakness in internal control over financial reporting solely related to our accounting for complex financial instruments. If we are unable to maintain an effective system of disclosure controls and procedures and internal control over financial reporting, we may not be able to accurately report our financial results in a timely manner, which may adversely affect investor confidence in us and materially and adversely affect our business and financial results.

Management concluded that it was appropriate to restate our previously issued audited balance sheet as of May 28, 2021, filed as Exhibit 99.1 to our Current Report on Form 8-K filed with the SEC on June 4, 2021, our

100

Table of Contents

unaudited interim financial statements included in our Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2021, filed with the SEC on August 6, 2021, and our unaudited interim financial statements included in our Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2021, filed with the SEC on November 10, 2021 due to an error in presentation of a portion of Class A Common Stock subject to redemption as permanent equity. As part of such process, we identified a material weakness in our internal

control over financial reporting, solely related to our accounting for complex financial instruments.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected and corrected on a timely basis. Effective internal controls are necessary for us to provide reliable financial reports and prevent fraud. We expect to take steps to remediate the material weakness, but there is no assurance that any remediation efforts will ultimately have the intended effects.

If we identify any new material weaknesses in the future, any such newly identified material weakness could limit our ability to prevent or detect a misstatement of our accounts or disclosures that could result in a material misstatement of our annual or interim financial statements. In such case, we may be unable to maintain compliance with securities law requirements regarding timely filing of periodic reports in addition to applicable stock exchange listing requirements, investors may lose confidence in our financial reporting and our stock price may decline as a result. We cannot assure you that the measures we have taken to date, or any measures we may take in the future, will be sufficient to avoid potential future material weaknesses.

The Business Combination is subject to conditions, including certain conditions that may not be satisfied on a timely basis, if at all.

The completion of the Business Combination is subject to a number of conditions. The completion of the Business Combination is not assured and is subject to risks, including the risk that approval of the Business Combination by DYNS stockholders is not obtained or that there are not sufficient funds in the Trust Account, in each case subject to certain terms specificed in the Business Combination Agreement (as described in the section entitled “The Business Combination Agreement – Conditions to Closing”), or that other Closing conditions are not satisfied. If DYNS does not complete the Business Combination, DYNS could be subject to several risks, including:

•

the parties may be liable for damages to one another under the terms and conditions of the Business Combination Agreement;

•

negative reactions from the financial markets, including declines in the price of our Class A Common Stock due to the fact that current prices reflect a market assumption that the Business Combination will be completed;

•

the attention of our management will have been divereted to the Business Combination rather than the pursuit of other opportunities in respect of an initial business combination; and

•

we will have a limited period of time, if any, to complete an alternative initial business combination and we may not be as attractive to potential altnerative partners to an initial business combination if we are unable to complete the Business Combination.

The ability of DYNS stockholders to exercise redemption rights with respect to a large number of shares of Class A Common Stock could increase the probability that the Business Combination would be unsuccessful and that stockholders would have to wait for liquidation in order to redeem their shares of Class A Common Stock.

At the time we entered into the Business Combination Agreement and related agreements for the Business Agreement, we did not know how many stockholders would exercise their redemption rights, and therefore we

101

Table of Contents

structured the Business Combination based on our expectations as to the number of shares that will be submitted for redemption. The Business Combination Agreement requires us to have at least $150 million of aggregate cash proceeds available from the Trust Account, after giving effect to redemptions of Public Shares, if any, and any transaction expenses. If a larger number of shares are submitted for redemption than we initially expected, this may limit our ability to complete the Business Combination or optimize our capital structure.

In connection with the execution of the Business Combination Agreement, the Sponsor, DYNS and each of the Anchor Investors entered into Non-Redemption Agreements. Pursuant to the Non-Redemption Agreements, each of the Anchor Investors agreed for the benefit of DYNS (a) to not redeem the shares of Class A Common Stock beneficially owned by it, or any other shares, capital stock or other equity interests, as applicable, of DYNS, which it held on December 19, 2021 and b) to not, among other things, sell encumber or otherwise transfer these shares. The shares of Class A Common Stock held by the Anchor Investors represent 8,691,655 shares of Class A Common Stock in the aggregate. However, pursuant to these Non-Redemption Agreements, the Anchor Investors may sell, encumber or otherwise transfer the shares of Class A Common Stock beneficially owned and held by them in connection with programmatic, non-discretionary sales required due to client redemptions (and not, for the avoidance of doubt, due to active portfolio management activity) in mutual funds managed or offered by each of the Anchor Investors. As a result of these sales, the number of non-redeemable Class A Common Stock under the Non-Redemption Agreements would be reduced, which would cause an increase in the number of redeemable Class A Common Stock. The subsequent holders of these shares of Class A Common Stock sold, encumbered or otherwise transferred from these sales have the right to demand that DYNS redeem their shares for a pro rata portion of the cash held in the Trust Account. If these shares are redeemed from the cash held in the Trust Account and the cash held in the Trust Account is subsequently decreased, DYNS may not be able to guarantee there being at least $150,000,000 in Available Closing Cash (as defined in the Business Combination Agreement), which is a condition DYNS is required to perform in order to consummate the Business Combination Agreement. Pursuant to the Business Combination Agreement, Senti may a) extend the time for the performance of any of the obligations or other acts required of DYNS as set forth in the Business Combination Agreement or b) waive compliance by DYNS with any of the agreements or conditions set for the in the Business Combination Agreement. However, DYNS cannot guarantee that Senti will grant such an extension or waiver.

There is no guarantee that a stockholder’s decision to continue to hold shares of Class A Common Stock following the Business Combination will put the stockholder in a better future economic position than if they decided to redeem their Public Shares for a pro rata portion of the Trust Account will put the stockholder in a better future economic position, and vice versa.

DYNS can give no assurance as to the price at which a stockholder may be able to sell its Public Shares in the future following the completion of the Business Combination or any alternative business combination. Certain events following the consummation of any initial business combination, including the Business Combination, may cause an increase in DYNS’s share price, and may result in a lower value realized now than a stockholder of DYNS might realize in the future had the stockholder redeemed their shares. Similarly, if a stockholder does not redeem their shares, the stockholder will bear the risk of ownership of the Public Shares after the consummation of any initial business combination, including the Business Combination, and there can be no assurance that a stockholder

102

Table of Contents

can sell its shares in the future for a greater amount than the redemption price set forth in this proxy statement/prospectus. A stockholder should consult the stockholder’s own tax and/or financial advisor for assistance on how this may affect his, her or its individual situation.

If DYNS stockholders fail to comply with the redemption requirements specified in this proxy statement/ prospectus, they will not be entitled to redeem their Class A Common Stock for a pro rata portion of the funds held in the Trust Account.

In order to exercise their redemption rights, Public Stockholders are required to submit a request in writing and deliver their stock to DYNS’s transfer agent at least two business days prior to the Special Meeting. Stockholders electing to redeem their shares will receive their pro rata portion of the Trust Account less income taxes payable, calculated as of two business days prior to the anticipated consummation of the Business Combination. See the section entitled “Special Meeting of DYNS Stockholders—Redemption Rights” for additional information on how to exercise your redemption rights.

Stockholders of DYNS who wish to redeem their shares for a pro rata portion of the Trust Account must comply with specific requirements for redemption that may make it more difficult for them to exercise their redemption rights prior to the deadline.

Public Stockholders who wish to redeem their shares for a pro rata portion of the Trust Account must, among other things, as fully described in the section entitled “Special Meeting of DYNS Stockholders— Redemption Rights,” deliver their shares (either physically or electronically) to Continental (or through DTC to Continental) prior to , local time, on , 2022.

If you or a “group” of stockholders of which you are a part are deemed to hold an aggregate of more than 20% of DYNS Common Stock issued in the Initial Public Offering, you (or, if a member of such a group, all of the members of such group in the aggregate) will lose the ability to redeem all such shares in excess of 20% of common stock issued in the Initial Public Offering.

A Public Stockholder, together with any of his, her or its affiliates or any other person with whom he, she or it is acting in concert or as a “group” (as defined under Section 13 of the Exchange Act), will be restricted from redeeming in the aggregate his, her or its shares or, if part of such a group, the group’s shares, with respect to

20% or more of the Public Shares issued in the Initial Public Offering. In order to determine whether a stockholder is acting in concert or as a group with another stockholder, DYNS will require each Public Stockholder seeking to exercise redemption rights to certify to DYNS whether such stockholder is acting in concert or as a group with any other stockholder. Such certifications, together with other public information relating to stock ownership available to DYNS at that time, such as Section 13D, Section 13G and Section 16 filings under the Exchange Act, will be the sole basis on which DYNS makes the above-referenced determination. Your inability to redeem any such excess shares will reduce your influence over DYNS’s ability to consummate the Business Combination and you could suffer a material loss on your investment in DYNS if you sell such excess shares in open market transactions. Additionally, you will not receive redemption distributions with respect to such excess shares if DYNS consummates the Business Combination. As a result, you will continue to hold that number of shares aggregating to more than 20% of the shares sold in the Initial Public Offering and, in order to dispose of such excess shares, would be required to sell your stock in open market transactions, potentially at a loss. DYNS cannot assure you that the value of such excess shares will appreciate over time following the Business Combination or that the market price of Class A Common Stock will exceed the per-share redemption price. Notwithstanding the foregoing, stockholders may challenge DYNS’s determination as to whether a stockholder is acting in concert or as a group with another stockholder in a court of competent jurisdiction.

However, DYNS’s stockholders’ ability to vote all of their shares (including such excess shares) for or against the Business Combination is not restricted by this limitation on redemption.

SPECIAL MEETING OF DYNS STOCKHOLDERS

General

DYNS is furnishing this proxy statement/prospectus to its stockholders as part of the solicitation of proxies by the Board for use at the Special Meeting to be held on , 2022 and at any adjournment or postponement thereof. This proxy statement/prospectus provides DYNS’s stockholders with information they need to know to be able to vote or direct their vote to be cast at the Special Meeting.

Date, Time and Place

The Special Meeting will be held on , 2022, at AM, Eastern Time, via live webcast at the following address: . In light of the

COVID-19

pandemic and to support the well-being of DYNS’s stockholders, directors and management, the Special Meeting will be completely virtual.

Voting Power; Record Date

You will be entitled to vote or direct votes to be cast at the Special Meeting if you owned shares of DYNS Common Stock at the close of business on , 2022, which is the Record Date. You are entitled to one vote for each share of DYNS Common Stock that you owned as of the close of business on the Record Date. If your shares are held in “street name” or are in a margin or similar account, you should contact your broker, bank or other nominee to ensure that votes related to the shares you beneficially own are properly counted. On the Record Date, there were 29,465,500 shares of DYNS Common Stock outstanding, of which 23,000,000 are Public Shares, and 6,465,500 shares are held by the Sponsor.

Vote of the Sponsor, Directors and Officers

In connection with the Initial Public Offering, DYNS entered into agreements with each of its Sponsor, directors and officers pursuant to which each agreed to vote the Founder Shares, Private Placement Shares and any Public Shares owned by them in favor of the Business Combination Proposal and for all other proposals presented at the Special Meeting (including the Proposals).

DYNS’s Sponsor, directors and officers have waived any redemption rights with respect to the Founder Shares, Private Placement Shares and any Public Shares which they may hold, and the Sponsor has also agreed to waive its redemption rights with respect to any other equity securities of DYNS it holds, in connection with the Business Combination.

Quorum and Required Vote for Proposals

A quorum of DYNS stockholders is necessary to hold a valid meeting. A quorum will be present at the Special Meeting if a majority of the voting power of all outstanding shares of DYNS Common Stock entitled to vote at the meeting are represented in person (which would include presence at a virtual meeting) or by proxy. As of , 2022, the Record Date, there were 23,715,500 shares of Class A Common Stock and 5,750,000 shares of Class B Common Stock outstanding; therefore, a total of 14,732,751 shares of DYNS Common Stock must be represented at the Special Meeting in order to constitute a quorum. Abstentions and withheld votes will count as present for the purposes of establishing a quorum, but will not count as votes cast at the Special Meeting for any of the Proposals. Because the Proposals are

“non-discretionary”

items, your broker will not be able to vote uninstructed shares for any of the Proposals. As a result, if you do not provide voting instructions, a broker

“non-vote”

will be deemed to have occurred for each of the Proposals. Broker

“non-votes”

will not be counted as present for purposes of determining whether a quorum is present. As of the Record Date, the Sponsor holds approximately 21.9% of the outstanding DYNS Common Stock.

104

Table of Contents

The Proposals presented at the Special Meeting will require the following votes:

•

The approval of the Charter Amendment Proposal will require the affirmative vote of a majority of the issued and outstanding shares of each of the Class A Common Stock and Class B Common Stock, voting separately as well as the vote of a majority of the issued and outstanding shares of each of the Class A Common Stock and Class B Common Stock, voting together as a single class. Accordingly, a DYNS stockholder’s failure to vote by proxy or to vote in person (which would include presence at a virtual meeting) at the Special Meeting or an abstention will have the same effect as a vote “AGAINST” the Charter Amendment Proposal.

•

non-vote)

will not be counted in the nominee’s favor.

Abstentions and Broker

Non-Votes

At the Special Meeting, DYNS will count a properly executed proxy marked “ABSTAIN” with respect to a particular Proposal as present for purposes of determining whether a quorum is present. Because the Proposals are

“non-discretionary”

items, your broker will not be able to vote uninstructed shares for any of the Proposals. As a result, if you do not provide voting instructions, a broker

“non-vote”

will be deemed to have occurred for each of the Proposals. Broker

“non-votes”

will not be counted as present for purposes of determining whether a quorum is present. The failure to vote, abstentions and broker

non-votes

will not be counted as votes cast and will have no effect on any of the Proposals presented at the Special Meeting.

Recommendation of the Board

The Board has unanimously determined that each of the Proposals is fair to and in the best interests of DYNS and its stockholders, and has unanimously approved such Proposals. The Board unanimously recommends that stockholders:

•

vote “FOR” the Business Combination Proposal;

•

vote “FOR” the Charter Amendment Proposal;

•

vote “FOR” each of the Advisory Charter Amendment Proposals;

•

vote “FOR” the Nasdaq Stock Issuance Proposal;

•

vote “FOR” the Director Election Proposal;

•

vote “FOR” the Incentive Plan Proposal;

•

vote “FOR” the ESPP Proposal; and

•

vote “FOR” the Adjournment Proposal, if it is presented to the meeting.

105

Table of Contents

When you consider the recommendation of the Board in favor of approval of the Proposals, you should keep in mind that the Sponsor, members of the Board and officers of DYNS have interests in the Business Combination that are different from or in addition to (or which may conflict with) your interests as a stockholder. See “

Summary of the Proxy Statement/Prospectus—

Interests of the Sponsor and DYNS’s Directors and Officers in the Business Combination

” for additional information on interests of DYNS’s Sponsor, directors and executive officers.

Voting Your Shares

Each share of DYNS Common Stock that you own in your name entitles you to one vote. If you are a record owner of your shares, there are two ways to vote your shares of DYNS Common Stock at the Special Meeting:

•

You Can Vote By Signing and Returning the Enclosed Proxy Card

. If you vote by proxy card, your “proxy,” whose name is listed on the proxy card, will vote your shares as you instruct on the proxy card. If you sign and return the proxy card but do not give instructions on how to vote your shares, your shares will be voted as recommended by the Board “FOR” the Business Combination Proposal, the Charter Amendment Proposal, each of the Advisory Charter Amendment Proposals, the Nasdaq Stock Issuance Proposal, the Director Election Proposal, the Incentive Plan Proposal, the ESPP Proposal and the Adjournment Proposal (if presented). Votes received after a matter has been voted upon at the Special Meeting will not be counted.

•

You Can Attend the Special Meeting and Vote Through the Internet

. You will be able to attend the Special Meeting online and vote during the meeting by visiting

and entering the control number included on your proxy card or on the instructions that accompanied your proxy materials, as applicable.

If your shares are held in “street name” or are in a margin or similar account, you should contact your broker to ensure that votes related to the shares you beneficially own are properly counted. If you wish to attend the Special Meeting and vote online and your shares are held in “street name,” you must obtain a legal proxy from your broker, bank or nominee. That is the only way DYNS can be sure that the broker, bank or nominee has not already voted your shares.

Revoking Your Proxy

If you are a record owner of your shares and you give a proxy, you may change or revoke it at any time before it is exercised by doing any one of the following:

•

submit a new proxy card bearing a later date;

•

give written notice of your revocation to DYNS’s Secretary, which notice must be received by DYNS’s Secretary prior to the vote at the Special Meeting; or

•

vote electronically at the Special Meeting by visiting

and entering the control number found on your proxy card, voting instruction form or notice you previously received. Please note that your attendance at the Special Meeting will not alone serve to revoke your proxy.

If your shares are held in “street name” by your broker, bank or another nominee as of the close of business on the Record Date, you must follow the instructions of your broker, bank or other nominee to revoke or change your voting instructions.

No Additional Matters May Be Presented at the Special Meeting

The Special Meeting has been called only to consider the approval of the Business Combination Proposal, the Charter Amendment Proposal, each of the Charter Amendment Proposals, the Nasdaq Stock Issuance Proposal, the Director Election Proposal, the Incentive Plan Proposal, the ESPP Proposal and the Adjournment Proposal. Under DYNS’s bylaws, other than procedural matters incident to the conduct of the Special Meeting, no other matters may be considered at the Special Meeting if they are not included in this proxy statement/prospectus, which serves as the notice of the Special Meeting.

Redemption Rights

Pursuant to the Current Charter, any holders of Public Shares may demand that such shares be redeemed in exchange for a pro rata share of the aggregate amount on deposit in the Trust Account, less any owed but unpaid franchise or income taxes. If demand is properly made and the Business Combination is consummated, these shares, immediately prior to the Business Combination, will cease to be outstanding and will represent only the right to receive a pro rata share of the aggregate amount on deposit in the Trust Account which holds the proceeds of the Initial Public Offering (including interest earned on the funds held in the Trust Account and not previously released to DYNS to pay its franchise and income taxes). For illustrative purposes, based on funds in the Trust Account of $ on the Record Date, the estimated per share redemption price would have been approximately $ .

In order to exercise your redemption rights, you must:

•

check the box on the enclosed proxy card to elect redemption;

•

provide, in the written request to redeem your Public Shares for cash to Continental, a “Stockholder Certification” if you are not acting in concert or as a “group” (as defined in

Section 13d-3

of the Exchange Act) with any other stockholder with respect to shares of DYNS Common Stock; and

E-mail:

•

deliver your Public Shares either physically or electronically through DTC to Continental at least two business days before the Special Meeting. Public Stockholders seeking to exercise their redemption rights and opting to deliver physical certificates should allot sufficient time to obtain physical certificates from Continental and time to effect delivery. It is DYNS’s understanding that stockholders should generally allot at least two weeks to obtain physical certificates from Continental. However, DYNS does not have any control over this process and it may take longer than two weeks. Stockholders who hold their shares in “street” name will have to coordinate with their bank, broker or other nominee to have the shares certificated or delivered electronically. If you do not submit a written request and deliver your Public Shares as described above, your shares will not be redeemed.

Any demand for redemption, once made, may be withdrawn at any time until the deadline for exercising redemption requests (and submitting shares to the transfer agent) and thereafter, with DYNS’s consent, until the Closing. If you delivered your shares for redemption to Continental and decide within the required timeframe not to exercise your redemption rights, you may request that Continental return the shares (physically or electronically). You may make such request by contacting Continental at (917)

262-2373,

by email at proxy@continentalstock.com or by writing to the address listed above.

Table of Contents

Prior to exercising redemption rights, stockholders should verify the market price of Class A Common Stock as they may receive higher proceeds from the sale of their Class A Common Stock in the public market than from exercising their redemption rights if the market price per share is higher than the redemption price. We cannot assure you that you will be able to sell your shares of Class A Common Stock in the open market, even if the market price per share is higher than the redemption price stated above, as there may not be sufficient liquidity in Class A Common Stock when you wish to sell your shares.

If you exercise your redemption rights, your shares of Class A Common Stock will cease to be outstanding immediately prior to the Business Combination and will only represent the right to receive a pro rata share of the aggregate amount on deposit in the Trust Account. You will no longer own those shares and will have no right to participate in, or have any interest in, the future growth of the Combined Company, if any. You will be entitled to receive cash for these shares only if you properly and timely demand redemption.

If the Business Combination is not approved or completed for any reason, then Public Stockholders who elected to exercise their redemption rights will not be entitled to redeem their shares. In such case, DYNS will promptly return any Public Shares previously delivered by the Public Stockholders.

(2)	This scenario assumes that no public shares are redeemed.

(3)

This scenario assumes that Public Shares are redeemed, resulting in an aggregate payment of $ million out of the trust account, which is derived from the number of shares that could be redeemed in connection with the business combination at an assumed redemption price of $10.00 per share based on the trust account balance as of the Record Date.

(4)

This scenario assumes that 14,308,345 Public Shares are redeemed, resulting in an aggregate cash payment of approximately $143.1 million out of the Trust Account based on an assumed redemption price of $10.00 per share. This redemption figure is derived by substracting the 8,691,655 shares that will not be redeemed by Anchor Investors (due to Non- Redemption Agreements) from the 23,000,000 Public Shares issued and outstanding as at the Record Date. After a redemption of approximately $143.1 million out of the $230.0 million Trust Account, and the $66.8 million PIPE Investment, the available cash at Closing would be approximately $153.7 million, which would satisfy the condition in the Business Combination Agreement that there be at least $150.0 million in available Closing cash. When considering this maximum redemptions scenario, you should consider that the Anchor Investors’ commitments under the

Non-Redemption

Agreements not to redeem or to transfer their shares of Class A Common Stock do not apply in circumstances where they are compelled to do so in connection with non-discretionary ETF or mutual fund pro rata rebalancing transfers. If one or more Anchor Investors was compelled to transfer shares of Class A Common Stock for this reason, it is possible that more than 14,308,345 Public Shares could be redeemed and that there may not be $150,000,000 in cash available at Closing. As this condition is for Senti’s benefit, it is possible that Senti could waive it prior to Closing, although there is no guarantee that it would. The redemption of more than 14,308,345 Public Shares would change some of the figures presented in this scenario.

Dissenter Rights

DYNS stockholders do not have dissenter rights in connection with the Business Combination or the other Proposals.

Potential Purchases of Shares

In connection with the stockholder vote to approve the proposed Business Combination, the Sponsor, directors, officers or advisors or their respective affiliates may privately negotiate transactions to purchase DYNS Common Stock from stockholders who would have otherwise elected to have their shares redeemed in conjunction with a proxy solicitation pursuant to the proxy rules for a

per-share

pro rata portion of the Trust Account. None of DYNS’s Sponsor, directors, officers or advisors or their respective affiliates will make any such purchases when they are in possession of any material

non-public

information not disclosed to the seller or during a restricted period under Regulation M under the Exchange Act. Such a purchase would include a contractual acknowledgement that such stockholder, although still the record holder of DYNS Common Stock, is no longer the beneficial owner thereof and therefore agrees not to exercise its redemption rights, and could include a contractual provision that directs such stockholder to vote such shares in a manner directed by the purchaser. In the event that the Sponsor, directors, officers or advisors or their affiliates purchase shares in privately negotiated transactions from Public Stockholders who have already elected to exercise their redemption rights, such selling stockholders would be required to revoke their prior elections to redeem their shares. Any such privately negotiated purchases may be effected at purchase prices that are below or in excess of the

per-share

Background of the Business Combination

DYNS is a blank check company incorporated in the State of Delaware on March 1, 2021. The Company was formed for the purpose of entering into a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. While DYNS was not limited to pursue an acquisition opportunity in any business, industry or sector, DYNS focused on industries that complement our management team’s backgrounds, and capitalized on the ability of our management team to identify and acquire a business, focusing on the healthcare or healthcare-related industries. The transactions contemplated by the Business Combination Agreement and related agreements, including the Business Combination and PIPE Investment, are results of an extensive search for a potential transaction utilizing the networking, investing, operating and successful transaction experience of DYNS’s management team and Board of Directors.

The terms of the Business Combination Agreement and the various other agreements contemplated therein and herein are the results of extensive arms-length negotiations among DYNS, Senti and certain of its equity holders and their respective representatives. The following is a brief description of the background of these negotiations and summary of the key meetings and events that led to the signing of the Business Combination Agreement. The following chronology does not purport to catalogue every conversation among the parties to the Business Combination Agreement or their respective representatives.

On May 28, 2021, DYNS consummated its Initial Public Offering of 23,000,000 shares of Class A Common Stock (including 3,000,000 shares of Class A Common Stock that were issued pursuant to the underwriters’ exercise of their over-allotment option in full), at an offering price of $10.00 per share, generating, in the aggregate, gross proceeds of $230,000,000. Substantially concurrently with the consummation of our Initial Public Offering and the sale of the Class A Common Stock, we consummated a private placement of 715,500 shares of Class A Common Stock at a price of $10.00 per share, issued to the Sponsor, generating, in the aggregate, gross proceeds of $7,155,000. A total of $230,000,000 was placed in a U.S.-based trust account established for the benefit of our public stockholders.

Prior to the consummation of its Initial Public Offering, neither DYNS, nor anyone on its behalf, contacted any prospective target business or had any substantive discussions, formal or otherwise, with respect to a business combination with DYNS.

As described in the prospectus for its Initial Public Offering, DYNS’s business strategy was to identify and complete an initial business combination with a target that operates within the life sciences subsector and that complements the experience and expertise of our management team, directors and strategic advisors.

DYNS identified certain general, non-exclusive criteria and guidelines that it believed were important in evaluating prospective targets for our initial business combination. DYNS broadly focused on target businesses that it believed (i) have a compelling risk/reward proposition, (ii) have product candidates grounded in breakthrough science that have first-in-class and best-in-class competitive positioning, (iii) have product candidates or technologies with market-leading potential, (iv) have assets that could meet unmet medical needs with respect to multiple medical indications with the ability to diversify risk and successfully navigate an economic downturn and changes in the industry landscape, social sustainability trends and an evolving regulatory environment, (v) have an IPO-ready management team, and (vi) have an experienced investor base comprised of experienced life sciences investors who have also provided, and would likely continue to provide, strategic inputs to the company. DYNS believed that it was important to look for investments that satisfied many, though not necessarily all, of these criteria.

110

Table of Contents

After its Initial Public Offering, DYNS commenced an active search for prospective business combination candidates meeting much of the above criteria. DYNS contacted, and was contacted by, a number of individuals and entities with respect to business combination opportunities. During this search process, DYNS reviewed, and entered into preliminary discussions with respect to, a number of acquisition opportunities other than Senti.

During that process, DYNS’s management:

developed an initial list of over 70 potential business combination candidates (and subsequently several others), which were primarily identified through DYNS’s general industry knowledge and network and introductions from DYNS’s directors, advisors or contacts;

conducted at least one meeting with 25 potential business combination candidates;

conducted additional diligence on a subset of those 25 candidates, and entered into customary confidentiality and non-disclosure agreements with 11 potential business combination candidates; and

engaged in meaningful and detailed discussions, due diligence, and negotiations with four potential business combination candidates and their representatives, one of which was Senti.

During May 2021, as part of the process of developing an initial target list described above, DYNS’s management team held calls with its three independent directors – Jay Flatley, David Epstein, and Deep Nishar – and with Bob Langer (DYNS’s Chief Scientific Advisor) to help create a list of targets. During each of those four calls, the directors and Dr. Langer provided ideas of potential targets they knew about, and provided input on DYNS’s target list. In two of those four meetings, Senti came up as a potentially disruptive company with an interesting technology platform. Independently, members of DYNS’s management team heard about Senti from calls with people in their network.

In selecting the 25 potential business combination candidates that DYNS’s management team met with following development of the initial list of potential business combination candidates, DYNS’s management team focused on identifying businesses with a combination of all or certain the following general attributes:

have a large target market with favorable trends;

have a compelling risk/reward proposition;

have deep sector expertise in order to convert innovation into commercial success;

are grounded in breakthrough science (i.e.,

first-in-class

best-in-class

competitive positioning);

have potential market leading product candidates that could address an unmet medical need and provide significant benefits to patients;

have multiple assets with the ability to diversify risk and successfully navigate an economic downturn, and changes in the industry landscape, social sustainability trends and evolving regulatory environment;

have an

IPO-ready

management team; and

have an experienced investor base comprised of companies that have been funded by experienced life sciences investors, including venture capitalists, private equity investors, healthcare companies and other institutional investors who have also provided strategic inputs to the company.

Based on the foregoing criteria and evaluation of the targets, including additional diligence conducted on a subset of the 25 potential business combination candidates, DYNS’s management team determined to sign customary confidentiality and non-disclosure agreements with 11 targets, and then focused deeper evaluation, analysis and due diligence efforts on four potential business combination candidates, one of which was Senti.

Table of Contents

DYNS subsequently received, subject to confidentiality obligations requiring DYNS to keep such materials confidential, and DYNS’s management team reviewed business plans, financial statements and market size projections and certain other due diligence information of such four target businesses, one of which was Senti.

DYNS’s management team engaged in varying levels of further due diligence, evaluation and analysis and discussions with these four potential business combination targets. This additional due diligence, evaluation and analysis included access to materials in online data rooms and additional presentations and discussions with these potential business combination targets’ management and included, in addition to the general business and financial due diligence described in this section, with respect to the potential business combination targets:

a review and evaluation of certain financial and operating information of each business combination target;

scientific and technological analyses with assessment of product development, commercial, clinical, regulatory and reimbursement success factors of each business combination target;

review of market factors such as size, growth opportunity, competition, and development trends of each business combination target;

review of proprietary technology content of each business combination target;

commercial review of each business combination target, including, where relevant, interviews with key opinion leaders, customers, competitors and industry experts;

financial evaluation including analysis of historical results and modeling of various scenarios; and

review and evaluation of operations including R&D, manufacturing, sales, and distribution.

In addition to Senti, the other three potential targets included (i) a tools and services company focused on cell and gene therapy, (ii) a novel oncology therapeutic company based on a genomics based discovery platform, and (iii) a next generation diagnostics company.

While Senti was already on DYNS’s target list, on May 28, 2021, Timothy Lu, the Chief Executive Officer of Senti, reached out to the DYNS network to discuss a potential business combination with DYNS. On June 4, 2021, Mostafa Ronaghi and Rowan Chapman participated in an introductory call with Dr. Lu. On June 18, 2021, DYNS and Senti executed a mutual nondisclosure agreement in connection with DYNS’s consideration of a possible business combination involving Senti.

In subsequent weeks after entering a CDA on June 18, 2021 with Senti and until late August 2021, DYNS’s management team continued to conduct its evaluation, analysis and due diligence of multiple potential business combination targets across life science tools, diagnostics, synthetic biology and therapeutics.

On July 10, 2021, DYNS was granted access to the Senti virtual data room. From July 19, 2021 to July 21, 2021, DYNS and Senti held a series of

in-depth

business, operational, and strategy meetings regarding Senti’s business and operations, including

in-depth

discussions regarding the technology platform, R&D, manufacturing, commercial opportunity, and each of the three lead products. Following these

in-depth

discussions, while DYNS’s management conducted its evaluation, analysis and due diligence review of other potential business combination targets, from July 21, 2021 to July 29, 2021, the DYNS management team conducted due diligence, evaluation and analysis of Senti, including numerous calls with key opinion leaders in cell therapy and industry experts, while performing scientific and technological analyses to assess the product development, commercial, clinical, regulatory and reimbursement success factors of Senti.

Following such additional due diligence in July and through late August 2021, evaluation and analysis of Senti and the three other potential targets referred to above, and following initial discussions with the management team of Senti and each of those three other potential business combination targets, DYNS determined not to pursue any further potential transaction with such other potential business combination targets.

112

Table of Contents

In reaching its determination on potential business combination targets, including the three other potential business combination targets with which DYNS engaged in due diligence, evaluation, analysis and discussions as described above, the management of DYNS considered a variety of factors, including:

lack of

first-in-class

best-in-class

product candidates competitive positioning based upon scientific and technological analyses performed by DYNS, and review of proprietary technology content of such business combination targets;

lack of public company readiness based upon a review and evaluation of operations including financials, R&D, manufacturing, sales, and distribution;

questions about financial projections and commercial uptake;

concerns about valuation and risk of over-paying; and

mutual decisions to pursue potential alternative transactions.

Based on the additional due diligence, evaluation and analysis of Senti, DYNS’s decision to pursue a transaction with Senti was based on an investment thesis that Senti (i) has a compelling risk/reward proposition, (ii) has product candidates grounded in breakthrough science that have first-in-class and best-in-class competitive positioning, (iii) has product candidates or technologies with market-leading potential, (iv) has assets that could meet unmet medical needs with respect to multiple medical indications with the ability to diversify risk and successfully navigate an economic downturn and changes in the industry landscape, social sustainability trends and an evolving regulatory environment, (v) has an IPO-ready management team, and (vi) has an experienced investor base comprised of experienced life sciences investors who have also provided, and would likely continue to provide, strategic inputs to Senti.

Based on our diligence on evaluation of public comparables and conversations with our advisors, on July 28, 2021, two of our directors, Dr. Farokhzad and Dr. Ronaghi met with Dr. Lu for a dinner meeting where valuation in the range of approximately $300 million to $400 million was discussed, pending further more definitive input from DYNS’s advisors.

On August 1 and 2, 2021, at DYNS’s request, representatives of J.P. Morgan Securities LLC (“J.P. Morgan”) met with the management of DYNS to provide preliminary advice relating to DYNS’s preparation and submission of a

non-binding

letter of intent to acquire Senti. J.P. Morgan was not engaged to act as financial advisor to DYNS prior to or after such meeting. Later, on August 1, 2021, DYNS discussed the preparation and submission of a

non-binding

letter of intent with representatives of Davis Polk & Wardwell LLP (“Davis Polk”), legal advisors to DYNS.

On August 4, 2021, the board of directors of DYNS held a telephonic meeting in which senior management and representatives of Davis Polk were in attendance to discuss the submission of a

non-binding

letter of intent to acquire Senti. At DYNS’s request, representatives of J.P. Morgan also attended such meeting to provide preliminary advice relating to such submission. After internal discussion among DYNS’s management team and the board of directors of DYNS, and with the unanimous approval of the board of directors of DYNS, on August 5, 2021, DYNS delivered a first draft to Senti of a

non-binding

letter of intent, which included the following core terms:

•

an equity value of Senti equal to $300 million, payable solely in the form of shares of DYNS Class A Common Stock;

•

financing consisting of (i) $230,0000,000 of equity capital from DYNS’s trust account and (ii) a PIPE financing of between $100,000,000 and $125,000,000;

•

certain conditions to the consummation of the business combination, including stockholder approval and other customary matters, including the receipt of all applicable stock exchange clearances and, solely in respect of Senti’s obligations to consummate the business combination, a minimum cash condition of up to $200,000,000 (before giving effect to any transaction expenses);

113

Table of Contents

•

approximately $350,000,000 of cash being made available to the combined company for use as working capital and for general corporate purposes, including the payment of transactions expenses (assuming no redemptions by Public Stockholders and a PIPE financing of $120,000,000);

•

a board of directors of the combined company consisting of (i) four directors designated by Senti (one of which will be the chief executive officer of Senti), (ii) two directors designated by the Sponsor and (iii) one director mutually agreed by Senti and DYNS;

•

180-day

lock-up

for shares issued in connection with the business combination to existing Senti stockholders;

•

the

lock-up

applicable to Founder Shares and Private Placement Shares held by the Sponsor described in the prospectus for our Initial Public Offering would continue to apply;

•

any filing, registration or similar fees would be borne 50% by Senti and 50% by DYNS;

•

a customary post-closing incentive equity plan with an initial number of shares reserved and an “evergreen” provision that are customary for recent initial public offerings of companies in Senti’s industry; and

•

45-day

period of exclusivity in respect of Senti during which the parties would continue diligence and engage in negotiations to determine agreement on the terms of a definitive agreement (subject to a

30-day

extension if the parties mutually determine that satisfactory progress has been made in the negotiation of the definitive agreements).

Following the receipt of the

non-binding

letter of intent, Senti requested a discussion with DYNS to review and discuss the details of the

non-binding

letter of intent and to engage in additional negotiations. On August 8, 2021, Senti and DYNS held a call to further discuss and negotiate the

non-binding

letter of intent.

On August 15, 2021, Senti sent a markup to the

non-binding

letter of intent to DYNS, providing, among other things that (i) exclusivity would be mutual and extend for an initial period of ten days, with a 35 day extension if the Anchor Investors indicate a satisfactory level of support for the proposed business combination, (ii) that all outstanding equity awards of Senti would be excluded in the allocation of the equity value to the existing Senti stockholders, (iii) proposing an earnout to Senti’s existing stockholders of a number of additional shares equal to 8% of the equity value to vest in three tranches upon the achievement of certain share price milestones, (iv) increasing the minimum cash condition to $250,000,000 (after giving effect to any transaction expenses), (v) that 100% of any filing, registration or similar fees would be borne by DYNS, (vi) that the executive officers of Senti would continue to be the management of the Combined Company with substantially similar roles and responsibilities, (vii) that the Combined Company board would only include one director designated by the Sponsor and (viii) a post-closing incentive equity plan with an initial number of shares reserved for issuance of between 16% and 21% of the outstanding capital stock of the Combined Company and a customary “evergreen” provision and a post-closing employee stock purchase plan with an initial number of shares reserved for issuance of between 1% and 2% of the outstanding capital stock of the Combined Company and a customary “evergreen” provision. Later that day, DYNS reviewed and discussed the revised

non-binding

letter of intent received from Senti with representatives of Morgan Stanley, in its capacity as DYNS’s financial advisor, and Davis Polk, in detail. At DYNS’s request, representative of J.P. Morgan also attended such meeting to provide preliminary advice relating to the revised non-binding letter of intent.

After further internal deliberations between DYNS’s management team and its board of directors – and continued diligence on two of the above-mentioned targets during August 2021 – on August 17, 2021, DYNS delivered an updated

non-binding

letter of intent to Senti. The updated

non-binding

letter of intent also proposed (i) a mutual exclusivity period of 30 days, in which some of DYNS’s investors would be brought over the wall to review the opportunity and the proposed PIPE financing, with a 30 day extension if Senti and DYNS mutually agree that the Anchor Investors had indicated a satisfactory level of support for the proposed business combination, (ii) including all outstanding equity awards of Senti in the allocation of the equity value to the existing Senti stockholders, (iii) reducing the size of the earnout to 2,000,000 shares vesting in two equal tranches upon the achievement of certain share price milestones within a period of two and three years, respectively with respect to

114

Table of Contents

each tranche, following the closing or earlier upon a change of control in which the share price milestone is achieved, which number of shares and vesting parameters were determined by DYNS with the advice of its financial advisors based on the valuation of Senti, (iv) increasing the number of directors designated by our Sponsor to two directors, (v) reducing the minimum cash condition to $200,000,000 (before giving effect to any transaction expenses), (vi) that filing, registration or similar fees would be borne 50% by Senti and 50% by DYNS and (vii) reducing the amount of the shares initially reserved under the post-closing incentive equity plan to 16% of the outstanding capital stock of the combined company, of which 13.5% out of such 16% reserved for issuance would be granted at consummation of the business combination in the form of stock options.

During August 2021, the DYNS management team continued to conduct extensive due diligence, evaluation and analysis of Senti, including numerous calls with experts in cell therapy, oncology, disease indications for Senti products, and cell therapy manufacturing and production, and DYNS also retained an independent law firm to conduct intellectual property due diligence.

On August 25, 2021, Senti sent a markup to DYNS’s August 17, 2021 draft of the

non-binding

letter of intent. Senti accepted most of the terms from the August 17, 2021 draft but (i) proposed that the Anchor Investors would enter into

non-redemption

agreements in connection with the business combination and (ii) increased the amount of the shares initially reserved under the post-closing incentive equity plan to 21% of the outstanding capital stock of the combined company, of which 15% out of such 21% reserved for issuance would be granted at consummation of the business combination in the form of stock options.

On August 26, 2021 representatives of Davis Polk met with the management of DYNS to discuss Senti’s revised

non-binding

letter of intent, including, among other topics, the proposal that the funds and accounts managed by Counterpoint Global (Morgan Stanley Investment Management) and T. Rowe would enter into

non-redemption

agreements in connection with the business combination.

On August 26, 2021, the board of directors of DYNS held a telephonic meeting in which senior management and representatives of Davis Polk were in attendance to discuss the execution of a

non-binding

letter of intent to acquire Senti. After internal discussion among DYNS’s management team and the board of directors of DYNS, the board of directors of DYNS unanimously approved the execution and delivery of a

non-binding

letter of intent, which included the following core terms:

•

an equity value of Senti equal to $300,000,000 (before accounting for the benefit of the earnout available to existing Senti stockholders), payable solely in the form of shares of DYNS Class A Common Stock;

•

financing consisting of (i) $230,0000,000 of equity capital from DYNS’s trust account, (ii) a PIPE financing of between $100,000,000 and $125,000,000 and

(iii) non-redemption

agreements from the funds and accounts managed by Counterpoint Global (Morgan Stanley Investment Management) and T. Rowe;

•

an earnout to Senti’s existing stockholders of 2,000,000 additional shares to vest in two equal tranches of 1,000,000 shares upon the achievement of certain share price milestones within a period of two and three years, respectively with respect to each tranche, following the closing or earlier upon a change of control in which the share price milestone is achieved, which number of shares and vesting parameters were determined by the parties with the advice of their respective financial advisors;

•

certain conditions to the consummation of the business combination, including shareholder approval and other customary matters, including the receipt of all applicable stock exchange clearances and, solely in respect of Senti’s obligations to consummate the business combination, a minimum cash condition of at least $200,000,000 (before giving effect to any transaction expenses);

•

approximately $350,000,000 of cash being made available to the Combined Company for use as working capital and for general corporate purposes, including the payment of transactions expenses (assuming no redemptions by Public Stockholders and a PIPE financing of $120,000,000);

115

Table of Contents

•

a board of directors of the Combined Company consisting of (i) four directors designated by Senti (one of which will be the chief executive officer of Senti), (ii) two directors designated by our sponsor and (iii) one director mutually agreed by Senti and DYNS;

•

180-day

lock-up

for shares issued in connection with the business combination to existing Senti stockholders;

•

the

lock-up

applicable to Founder Shares and Private Placement Shares held by our Sponsor described in the prospectus for our Initial Public Offering would continue to apply;

•

any filing, registration or similar fees would be borne 50% by Senti and 50% by DYNS;

•

a post-closing incentive equity plan with an initial number of shares reserved for issuance of 21% of the outstanding capital stock of the combined company, of which 15% out of such 21% reserved for issuance would be granted at consummation of the business combination in the form of stock options, and a customary “evergreen” provision, and a post-closing employee stock purchase plan with an initial number of shares reserved for issuance of between 1% and 2% of the outstanding capital stock of the combined company and a customary “evergreen” provision; and

•

a mutual exclusivity period of 30 days, with a

30-day

extension if Senti and DYNS mutually agreed that the Anchor Investors have indicated a satisfactory level of support for the proposed business combination.

On the evening of August 26, 2021, with the unanimous approval of the board of directors of DYNS and the prior approval of the board of directors of Senti, DYNS and Senti executed the

non-binding

letter of intent (the “LOI”).

Following entry into the LOI, DYNS conducted confirmatory diligence in the subsequent weeks through September 2021, including calls with experts and third-party consultants, to further assess the technology, manufacturing, commercial opportunity, and the target product profile for each of Senti’s lead programs, and also conducted intellectual property due diligence. During September 2021, DYNS also spoke with Spark (Roche) and BlueRock to discuss their collaborations with Senti and why they selected Senti to work with.

On August 31, 2021, representatives of Goodwin Procter LLP (“Goodwin”) and Cooley LLP, legal advisors to Senti, held an introductory call with Davis Polk to discuss the proposed business combination and certain due diligence matters, including, among other topics, a review of the virtual data room established in connection with the proposed business combination and an introduction to legal due diligence topics related to Senti.

On September 3, 2021, representatives of DYNS, Senti, J.P. Morgan, Morgan Stanley, BofA Securities and the respective legal advisors held an introductory call, led by Dr. Farokhzad, DYNS’s Executive Chairman, and Dr. Ronaghi, DYNS’s Chief Executive Officer, to discuss the proposed PIPE financing timeline, the work streams for the PIPE financing, and investor targets.

On September 3, 2021, Davis Polk was granted access to the Senti virtual data room and began conducting legal due diligence. Between September 7, 2021 and September 8, 2021, representatives of Davis Polk, DYNS, Senti, Goodwin, and certain other participants, participated in numerous financial and legal due diligence calls.

Between September 3, 2021 and September 22, 2021, representatives of J.P. Morgan, Morgan Stanley, BofA Securities, Davis Polk, and Goodwin assisted Senti and DYNS, based on materials and information provided by the companies, with the investor presentation for the Anchor Investors of DYNS as potential investors in the PIPE financing. The investor presentation outlined the proposed business combination and included information regarding Senti, which was refined through several rounds of review and comment amongst DYNS’s management team, Senti’s management team and their respective advisors. Representatives of Davis Polk and Goodwin also assisted Senti and DYNS in securing non-redemption commitments in respect of such investors’ holdings of DYNS’s Class A Common Stock.

116

Table of Contents

On September 20, 2021, DYNS executed an engagement letter with J.P. Morgan, Morgan Stanley and BofA Securities, effective as of August 28, 2021, pursuant to which J.P. Morgan, Morgan Stanley and BofA Securities were engaged as joint placement agents to DYNS in connection with the potential PIPE financing. Both DYNS and Senti consented to the engagement of BofA Securities as a placement agent to DYNS prior to BofA Securities’ engagement as a placement agent.

On September 22, 2021, following the completion of the investor presentation, representatives of J.P. Morgan, Morgan Stanley, BofA Securities and DYNS began marketing an investment in the PIPE financing to a limited number of DYNS’s investors and representatives of Davis Polk and Goodwin assisted Senti and DYNS seeking non-redemption commitments in respect of such investors’ holdings of Class A Common Stock.

In late September 2021, DYNS and Senti agreed to extend the initial

30-day

period of the LOI to secure PIPE investment commitments and

non-redemption

agreements, before going more broadly to PIPE marketing beyond the limited group of DYNS’s investors.

By the end of October, after feedback from the Anchor Investors and potential PIPE investors, Senti and DYNS decided that, based on discussions with the Anchor Investors and other potential PIPE investors and adverse changes in market conditions, it was clear that the parties would need to negotiate a valuation of Senti that was more attractive to prospective PIPE investors and the Anchor Investors, from whom non-redemption commitments had been requested. During October and November 2021, representatives of Davis Polk and DYNS held numerous discussions with Anchor Investors of DYNS regarding potential non-redemption commitments on terms that would be mutually satisfactory to such Anchor Investors, and DYNS, including a revised valuation of Senti. DYNS then discussed the potential revised valuation with Senti on or around October 31, 2021. During this meeting, Senti reiterated its need for non-redemption agreements from the Anchor Investors in order to agree to a reduction in valuation. In order to secure the non-redemption agreements from the Anchor Investors, the Sponsor agreed to give up approximately 17% of Founder Shares.

Once DYNS agreed to continue to pursue the non-redemption agreements, Senti discussed the transaction and reduced valuation with its board of directors on November 8, 2021. After discussion, Senti’s board of directors indicated its continued support for Senti to pursue the potential business combination.

On November 15, 2021, the DYNS board held a teleconference meeting with Davis Polk in attendance, where DYNS’s management reviewed investor feedback from the first stage of the LOI, and based on initial feedback and adverse market conditions for SPACs and therapeutics/cell therapy public companies, management proposed (i) reducing the size of the PIPE financing from $120 million to $75 million, (i) reducing the valuation from $300 million to $240 million fully-diluted

pre-money

equity value, and (iii) offering Anchor Investors economic consideration to secure

non-redemption

agreements in the form of new shares, with commensurate forfeiture of Founder Shares by the Sponsor to prevent dilution and help DYNS secure

non-redemption

commitments. The DYNS board agreed that it made sense to proceed with those changes. The $240 million proposed valuation corresponded to an approximate 11% increase over Senti’s independently valued Series B equity financing, priced in the summer of 2020. Between the summer of 2020 and November 2021, the Senti management team had made significant progress across all dimensions of the business, including talent acquisition, R&D, pipeline advancement, intellectual property, manufacturing, and business development, comprising of establishing collaborations with Spark (Roche) and BlueRock (Bayer).

Between August 2021 and the signing of the Business Combination Agreement in December 2021, dozens of calls were held between Dr. Farokhzad and Dr. Lu—between the DYNS management team and its advisors or between broader Senti management and DYNS management—covering numerous topics including deal terms, valuation, board composition, Senti management incentives and employment agreements, milestones, cash burn, public market dynamics, technical development, scientific advances in the field, alternative approaches to manufacturing, potential business development opportunities, detailed discussion of risks as well as other matters.

117

Table of Contents

In addition, DYNS’s independent director, David Epstein, met with Dr. Lu telephonically on September 20, 2021 and December 21, 2021 for a detailed corporate presentation and answered Mr. Epstein’s questions. Mr. Epstein is uniquely qualified for Senti’s business matters having served as former CEO of Novartis Pharma, where he was involved in numerous new drug applications, and more recently having served as Executive Chairman of Rubius Therapeutics (Nasdaq: RUBY), a cell therapy platform company. Part of the basis for those calls was to explore Mr. Epstein joining Senti’s board.

On November 18, 2021, after further internal deliberations between DYNS’s management team, its board of directors and its financial advisors regarding the feedback from the Anchor Investors and other potential PIPE investors, DYNS delivered an updated

non-binding

letter of intent to Senti proposing, among other things, the following modifications to the LOI: (i) reducing the equity value of Senti from $300,000,000 to $240,000,000, (ii) reducing the size of the PIPE financing to $75,000,000, (iii) proposing that each of the funds and accounts managed by Counterpoint Global (Morgan Stanley Investment Management), T.

Between November 19, 2021 and December 2, 2021, Davis Polk prepared a first draft of the Business Combination Agreement, substantially reflecting the terms agreed to in the A&R LOI, which draft DYNS reviewed and discussed with Davis Polk in detail.

On December 2, 2021, Davis Polk sent Goodwin the first draft of the Business Combination Agreement.

On December 9, 2021, Goodwin sent Davis Polk their markup of the first draft of the Business Combination Agreement, which DYNS reviewed and discussed with Davis Polk.

On December 10, 2021, the board of directors of Senti held a telephonic meeting in which senior management were in attendance. Also in attendance were representatives of Goodwin and observers of the board of directors. The draft of the Business Combination Agreement and ancillary documents thereto, the status of the PIPE financing related to the Business Combination and Agreement, and negotiation and timing considerations for these transactions was reviewed and discussed. The board of directors engaged in extensive discussions and deliberations with Senti management and advisors with regard to these transactions.

On December 11, 2021, following further internal discussions between DYNS management and its legal advisors, Davis Polk provided Goodwin a revised draft of the Business Combination Agreement that, among other things, (i) revised certain interim operating covenants in respect of Senti’s operations, (ii) reflected that expenses will be borne 50% by DYNS and 50% by Senti and (iii) increased the ability of DYNS to incur working capital loans which DYNS may incur from $1,000,000 to $2,000,000.

On December 14, 2021, Goodwin sent Davis Polk its markup of the December 11, 2021 draft of the Business Combination Agreement, which DYNS reviewed and discussed with Davis Polk.

Between December 14, 2021 and December 19, 2021, representatives of each of DYNS, Senti, Davis Polk and Goodwin met telephonically and exchanged numerous emails to finalize the remaining open items related to the Business Combination Agreement and the other agreements contemplated therein. Following these discussions, representatives from Davis Polk and Goodwin exchanged revised drafts of the Business Combination Agreement and such other agreements, which reflected the outcome of their discussions. In addition, during this period, DYNS negotiated and entered into (i) an engagement letter with J.P. Morgan,

119

Table of Contents

pursuant to which J.P. Morgan was engaged as DYNS’s capital markets advisor to provide certain capital markets advisory services in connection with the proposed business combination and (ii) an engagement letter with Morgan Stanley pursuant to which Morgan Stanley was engaged as DYNS’s financial advisor to provide certain financial advisory services in connection with the proposed business combination.

On December 15, 2021, the board of directors of Senti held a meeting via videoconference in which senior management of Senti and Goodwin were in attendance. During this meeting, the draft of the Business Combination Agreement and ancillary documents thereto, the status of the PIPE financing related to the proposed business combination, and negotiation and timing considerations for these transactions were reviewed and discussed. The board concluded this meeting by indicating their continued support for the transaction.

On December 16, 2021, the board of directors of DYNS held a telephonic meeting in which senior management were in attendance. Also in attendance were representatives of Davis Polk, J.P. Morgan, and Morgan Stanley. Prior to the meeting, a slide deck summarizing the significant transaction documents was distributed to the directors with the transaction documents in substantially final form. Dr. Farokhzad updated DYNS’s board of directors on the final due diligence findings and the terms of the proposed business combination, including the resolution of the final outstanding items. Representatives of Morgan Stanley, as financial advisor to DYNS, reviewed the materials prepared by DYNS’s management and Senti with DYNS’s board of directors, and discussed current market conditions and trading valuations of similar public companies in the biotech industry, to aid the DYNS board of directors in its evaluation of the proposed transaction (though Morgan Stanley was not asked to provide, and did not provide, a financial opinion regarding the proposed transaction).

DYNS’s board of directors discussed the manner in which the management of DYNS initially determined, and then subsequently adjusted, the valuation of the consideration, which was based on market conditions and valuation analysis prepared by DYNS’s management team. A representative of Davis Polk reviewed with the board of directors the fiduciary duties that applied to their consideration of the proposed business combination. A representative of Davis Polk then discussed with the board of directors the proposed terms of the Business Combination Agreement, the PIPE subscription agreements, the

non-redemption

agreements, the other transaction documents to be entered into in connection with the proposed business combination and the timeline to closing. The board of directors then engaged in extensive discussions and deliberations with DYNS management and advisors. Among other things, the board of directors asked questions pertaining to legal due diligence, valuation, feedback from the Anchor Investors and proposed PIPE investors, risks, timing and process to closing. Following these discussions and deliberations, DYNS’s three independent directors held an executive session to further discuss the merits of the proposed business combination. Upon rejoining the broader board of directors meeting, the three independent directors engaged in an additional questions and answers session. The board subsequently determined by a unanimous vote that the proposed business combination is in the best interests of DYNS and its stockholders and adopted resolutions (i) approving the proposed business combination, the Business Combination Agreement and the consummation of the transactions contemplated thereby and (ii) recommending that the proposed business transaction be submitted to DYNS’s stockholders for approval.

Between December 10 and December 16, 2021, members of Senti’s management provided updates on the status of the proposed transaction to its board of directors, including a slide deck summarizing the proposed business combination, and discussed and deliberated with its directors, via email and telephonic meetings, the outstanding items and any resolutions on the proposed transaction. Additionally, during this period, it was generally agreed upon between Senti and DYNS that Senti’s stockholders would be subject to a twelve-month lock-up period following the consummation of the proposed business combination, while certain large stockholders of Senti would be subject to an eighteen month lock-up period following the consummation of the proposed business combination. Throughout the period, the board of directors of Senti indicated their continued support for the transactions contemplated by the draft of the Business Combination Agreement, subject to further revisions by the authorized officers of Senti.

Agreement and ancillary documents thereto, the status of the PIPE financing related to the proposed business combination, and negotiation and timing considerations for these transactions were reviewed and discussed. The board concluded this meeting by indicating their continued support for the transaction.

On December 17, 2021, Senti distributed the proposed transaction documents in substantially final form to its board of directors together with a board resolution seeking approval of the Business Combination, the proposed business combination and the related ancillary documents and the transactions contemplated therein.

On December 19, 2021, the board of directors of Senti determined by a written unanimous consent that the proposed business combination is in the best interests of Senti and its stockholders and adopted resolutions (i) approving the proposed business combination, the Business Combination Agreement, the PIPE Investment, and the consummation of the transactions contemplated thereby and (ii) recommending that the transaction be submitted to Senti’s stockholders for approval.

On December 19, 2021, following the approval of the proposed business combination by the board of directors of DYNS and Senti’s board of directors, DYNS, Senti, and certain other parties thereto, executed the Business Combination Agreement. Concurrently with the execution of the Business Combination Agreement, (i) DYNS, the Sponsor and certain other signatories thereto entered into the Sponsor Support Agreement (a copy of which is exhibited to the Business Combination Agreement), (ii) DYNS and the PIPE Investors entered into the subscription agreements in connection with the PIPE Investment, (iii) DYNS, the Sponsor and the funds and accounts managed by Counterpoint Global (Morgan Stanley Investment Management), T. Rowe, ARK and Invus entered into the

non-redemption

agreements, and (iv) DYNS and certain Senti equity holders entered into voting and support agreements in favor of DYNS and Senti.

On December 20, 2021, DYNS and Senti issued a joint press release regarding the proposed business combination and DYNS filed a Current Report on Form

8-K

with the SEC announcing the transactions contemplated by the Business Combination Agreement and filing with the SEC the Business Combination Agreement and certain other transaction documents. The final transaction terms (as detailed in the final investor presentation on file with the SEC) included a $240 million

pre-money

equity value for Senti, a $66.8 million PIPE financing, $86.9 million of

non-redemption

agreements with Anchor Investors, a pro forma equity market capitalization of $601 million and a pro forma enterprise value of $276 million (net of estimated transaction costs), in each case assuming no redemptions from the Trust Account.

Since December 20, 2021, DYNS and Senti, along with their respective advisors, have worked jointly on the preparation of this proxy statement/prospectus.

Throughout January 2022 and early February 2022, DYNS and Senti, along with their respective advisors, were in regular contact regarding the status of the capital markets in the United States and the market for

de-SPAC

transactions, in particular. In light of those discussions, DYNS and Senti, along with certain members of Senti’s executive team, agreed to restructure certain option grants made at the time the Business Combination Agreement was signed. In particular, certain Senti executives agreed to forfeit certain options granted to them at the time the Business Combination Agreement was signed depending on the level of redemptions of Public Shares at Closing; the options granted to all other employees at signing would, however, continue to be held by those employees after Closing, irrespective of the level of redemptions of Public Shares at Closing. In addition, it was agreed that the vesting period for the options held by executives whose options may be subject to forfeiture (as described above) will commence at Closing, whereas the vesting period for all other employees’ options commenced at the time the Business Combination Agreement was signed. These changes were given effect by the Business Combination Agreement Amendment, and by Senti and the relevant executives agreeing to amend the option award agreements they had previously entered into at the time the Business Combination Agreement was executed.

On or about February 12, 2022, Timothy Lu and Philip Lee’s (each a “Holder”) Senti Support Agreements were amended by the Amendment to Company Stockholder Support Agreement (the “Amendment to the Company Stockholder Support Agreement”). The “Lock-Up Release Date” for each of Dr. Lu and Dr. Lee were

121

Table of Contents

amended as defined below. “Lock-Up Release Date” means the earliest of (x)(i) the three year anniversary of the Closing with respect to the Shares, as defined in the Amendment, listed on Schedule I of the Amendment hereto only and subject to the parameters set forth on Schedule I of the Amendment, and (ii)(A) the one year anniversary of the Closing, with respect to all other Shares, as defined in the Amendment, that Holder may hold as of the date hereof or may hereafter acquire, and (B) subsequent to the Closing, if the last reported sale price of the Class A Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalization and the like) for any 20 trading days within any 30 consecutive trading day period commencing at least 150 days after the Closing, with respect to any Shares of Holder subject to a Lock-Up Release Date of the one year anniversary of the Closing, or (y) the date upon completion of a liquidation, merger, stock exchange, reorganization or other similar transaction that results in all of the public stockholders of New Senti having the right to exchange their New Senti common stock for cash, securities or other property.

DYNS and Senti have continued and expect to continue regular discussions regarding the execution and timing of the Business Combination and to take actions and exercise their respective rights under the Business Combination Agreement to facilitate the completion of the Business Combination.

Certain Engagements in Connection with the Business Combination and Related Transactions

Morgan Stanley was engaged by DYNS to act as financial advisor to DYNS in connection with the Business Combination, and will receive a customary advisory fee in connection therewith. DYNS also engaged Morgan Stanley to act as co-placement agent with J.P. Morgan and BofA Securities on its $66.8 million PIPE pursuant to which the co-placement agents will receive customary fees. In connection with its roles as financial advisor to DYNS and co-placement agent to DYNS on its PIPE herewith, Morgan Stanley will receive total fees of $1,889,776. In addition, DYNS engaged J.P. Morgan as capital markets advisor in connection with the Business Combination. J.P. Morgan also acted as underwriter on the initial public offering of DYNS and will receive a fee of $7,050,000 (this amount having being reduced from $8,050,000 by $1,000,000 by agreement with the underwriter on December 17, 2021) upon consummation of the Business Combination in connection therewith.

The Board’s Reasons for Approval of the Business Combination

DYNS was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. DYNS sought to do this by utilizing the networks and industry experience of both its management team and the Board to identify, acquire and operate one or more businesses within or outside of the United States.

The Board met via videoconference on December 16, 2021 to, among other things, discuss a potential business combination with Senti, and on December 16, 2021, unanimously approved the Business Combination

122

Table of Contents

and the Business Combination Agreement. Prior to reaching the decision to approve the Business Combination and the Business Combination Agreement, the Board consulted with our management, as well as with our legal and financial advisors.

In addition, the Board reviewed various industry and scientific data, including, but not limited to, Senti’s existing business model and Senti’s product candidates and development pipeline, and reviewed the results of management’s due diligence review of Senti, which took place over a period of more than five months beginning in July 2021 and continuing through the signing of the Business Combination Agreement on December 19, 2021, including extensive meetings and calls with Senti’s management team, review of Senti’s material contracts, intellectual property matters, labor matters, operations, financing and accounting due diligence, tax due diligence, engaging and consulting financial advisors, and other legal due diligence with assistance from our legal counsel and special intellectual property counsel before determining that the Business Combination was in the best interests of DYNS and its stockholders. The Board also determined, after a thorough review of other business combination opportunities reasonably available, that the Business Combination represents the best potential business combination based upon the process utilized to evaluate and assess other potential acquisition targets.

The Board considered a wide variety of factors in connection with its evaluation of the Business Combination. In light of the complexity of those factors, the Board as a whole did not consider it practicable to, nor did it attempt to, quantify or otherwise assign relative weights to the specific factors it took into account in reaching its decision. Individual members of the Board may have given different weight to different factors. This explanation of DYNS’s reasons for the Board’s approval of the Business Combination, and all other information presented in this section, is forward-looking in nature and, therefore, should be read in light of the factors discussed under the section entitled

“Forward-Looking Statements.”

In particular, the Board considered the following positive factors, although not weighted or in any order of significance:

•

Pioneering innovation in the field of gene circuit technology.

The Board believes that Senti has proven and experienced leadership, which is poised to execute on Senti’s unique approach to developing and manufacturing intelligent gene circuits for use in next-generation cell and gene therapies.

•

Anticipated FDA filings.

The Board considered Senti’s anticipated Investigational New Drug (IND) filings in 2023 for product candidates

SENTI-202

and

SENTI-301,

each of which is discussed in further detail in the section entitled

“Information About Senti.”

•

Collaborations with Spark and BlueRock.

The Board considered Senti’s existing collaborations with Spark (Roche) and BlueRock (Bayer), which are more fully described in the section entitled “

Information about Senti –

Material License and Collaboration Agreements

,” as providing additional validation of Senti’s clinical strategies.

•

Potential to address an area of high unmet medical need.

The Board considered the potential for Senti’s product candidates, should they proceed through clinical trials and be approved for use, to address patients with high unmet needs in oncology, immunology, genetic diseases, neurology, cardiology and ophthalmology, among others.

•

Diversified risk profile from multimodality approach.

The Board considered that Senti’s pipeline and platform has several potential therapeutic applications, including in the fields of oncology, gene therapies for tissue-directed targets and cell therapies for regenerative medicine applications. The Board believes that this multimodality approach will help Senti to diversity its business risk.

•

Development of the commercial potential of product candidates, if approved.

The Board believes that, driven by its understanding of existing treatment paradigms and patient, physician and payor needs, Senti is in a strong position to build a focused and efficient medical affairs and commercial organization and to commercialize its product candidates, if approved (including by the FDA), in the United States and international markets.

123

Table of Contents

•

Experienced and dedicated management team.

The Board believes that Senti has a proven and experienced management team that will effectively lead the Combined Company after the Business Combination. Additionally, the Board considered Senti’s management’s willingness to forfeit certain options with respect to redemptions and recognized the dedication of Senti’s management to attempt to execute on its business plans.

•

Backed by

top-tier

healthcare investors.

Senti’s existing investors include NEA, 8VC, Leaps by Bayer, Amgen Ventures, Lux, Matrix, Lifeforce Capital, among others, which the Board believes provides additional validation of Senti’s clinical and business strategies. The Board also considered the strong interest in the PIPE Investment in connection with the transaction from seasoned healthcare investors, including T. Rowe, funds and accounts managed by Counterpoint Global (Morgan Stanley Investment Management), Invus, NEA, 8VC, Lifeforce and others.

•

Financial analysis conducted by DYNS.

The financial analysis conducted by DYNS’s management team and reviewed by the Board supported the equity valuation of Senti.

The Board also identified and considered the following factors and risks weighing negatively against pursuing the Business Combination, although not weighted or in any order of significance:

•

Technical and Clinical Risk

. Senti is a preclinical stage biotechnology company, and the Board considered that there is no assurance that Senti will engage in clinical trials or that any clinical trials will succeed.

•

FDA Approval

. The Board considered risks associated with the failure to receive FDA approval (in a timely manner or at all) for Senti’s product candidates, should they ultimately reach late-stage clinical development, and the adverse impact that would have on the commercialization of its product candidates.

•

Manufacturing

. While Senti has plans to develop a manufacturing facility for its product candidates, the Board considered the risks associated with optimizing and scaling up production for clinical trials and commercial sales.

•

Commercialization

. The Board considered the risks that, should Senti’s product candidates proceed through clinical trials and receive FDA approval, they will nevertheless be unable to commercialize them and they will be subject to competition from other businesses involved in developing and commercializing “gene circuit” technology for programing next-generation cell and gene therapies.

•

Reimbursement

. The Board considered the risks that, should Senti’s product candidates proceed through clinical trials and receive FDA approval, they do not become eligible for third-party coverage and/or approved for reimbursement.

•

Exclusivity

. The Board considered the fact that the Business Combination Agreement includes an exclusivity provision that prohibits DYNS from soliciting other business combination proposals, which restricts DYNS’s ability, so long as the Business Combination Agreement is in effect, to consider other potential business combinations.

•

Other risks

. Various other risks associated with the Business Combination and redemptions, the business of DYNS and the business of Senti described in the section entitled “

Risk Factors,

” including Senti’s ongoing need to raise additional capital to finance its operations.

Based on its review of the forgoing considerations, the Board concluded that the potentially negative factors associated with the Business Combination were outweighed by the potential benefits that it expects DYNS stockholders will receive as a result of the Business Combination. The Board noted that there can be no assurance about future results, including results considered or expected as disclosed in the foregoing reasons.

The preceding discussion of the information and factors considered by the Board is not intended to be exhaustive but includes the material factors considered by the Board. In view of the complexity and wide variety

124

Table of Contents

of factors considered by the Board in connection with its evaluation of the Business Combination, the Board did not consider it practical to, nor did it attempt to, quantify, rank or otherwise assign relative weights to the different factors that it considered in reaching its decision. In addition, in considering the factors described above, individual members of the Board may have given different weight to different factors. The Board considered this information as a whole and overall considered the information and factors to be favorable to, and in support of, its determinations and recommendations.

This explanation of the Board’s reasons for its approval of the Business Combination, and all other information presented in this section, is forward-looking in nature and, therefore, should be read in light of the factors discussed under the section entitled “

Summary of Business Combination Agreement

This subsection of the proxy statement/prospectus describes the material provisions of the Business Combination Agreement, but does not purport to describe all of the terms of the Business Combination Agreement. The following summary is qualified in its entirety by reference to the complete text of the Business Combination Agreement, a copy of which is attached as

Annex

to this proxy statement/prospectus. You are urged to read the Business Combination Agreement in its entirety because it is the primary legal document that governs the Business Combination.

The Business Combination Agreement contains representations, warranties and covenants that the respective parties made to each other as of the date of the Business Combination Agreement or other specific dates. The assertions embodied in those representations, warranties and covenants were made for purposes of the contract among the respective parties and are subject to important qualifications and limitations agreed to by the parties in connection with negotiating the Business Combination Agreement. The representations, warranties and covenants in the Business Combination Agreement are also modified in part by the underlying disclosure schedules delivered by each of DYNS and Senti to each other (the “disclosure schedules”), which are not filed publicly and which are subject to a contractual standard of materiality different from that generally applicable to stockholders, and were used for the purpose of allocating risk among the parties rather than establishing matters as facts. We do not believe that the disclosure schedules contain information that is material to an investment decision. Additionally, the representations and warranties of the parties to the Business Combination Agreement may or may not have been accurate as of any specific date and do not purport to be accurate as of the date of this proxy statement/prospectus. Accordingly, no person should rely on the representations and warranties in the Business Combination Agreement or the summaries thereof in this proxy statement/prospectus as characterizations of the actual state of facts about DYNS, Merger Sub, the Sponsor, Senti or any other matter.

Structure of the Business Combination

On December 19, 2021, DYNS, Merger Sub and Senti entered into the Business Combination Agreement, which provides, among other things, that, on the Closing Date, the parties to the Business Combination Agreement will cause a certificate of merger to be executed and filed with the Secretary of State of the State of Delaware, pursuant to which Merger Sub will merge with and into Senti, with Senti as the surviving company in the merger and, after giving effect to such merger, Senti shall be a wholly owned subsidiary of DYNS.

Pursuant to the Business Combination Agreement, at the Effective Time:

•

each outstanding share of Senti common stock will be cancelled and converted into the right to receive a number of shares of Class A Common Stock equal to the Exchange Ratio (rounded down to the nearest whole share);

•

each outstanding share of Senti preferred stock will be cancelled and converted into the right to receive a number of shares of Class A Common Stock equal to (i) the aggregate number of shares of Senti common stock that would be issued upon conversion of the shares of Senti preferred stock based on the

125

Table of Contents

applicable conversion ratio immediately prior to the Effective Time, multiplied by (ii) the Exchange Ratio (rounded down to the nearest whole share); and

•

each outstanding option (whether vested or unvested) to purchase Senti stock will be converted into an option to purchase a number of shares of Class A Common Stock (rounded down to the nearest whole share) equal to (A) the number of shares of Senti common stock subject to such option as at the time immediately prior to the Effective Time, multiplied by (B) the Exchange Ratio, at an exercise price per share equal to the current exercise price per share for such option divided by the Exchange Ratio (rounded up to the nearest whole cent).

The consideration described in the foregoing bullets is collectively referred to as the “Business Combination Consideration.”

In addition, holders of shares of Senti common stock and Senti preferred stock will be eligible to receive (i) 1,000,000 shares of Class A Common Stock, in the aggregate, if, after Closing, the volume weighted average price of Class A Common Stock on Nasdaq, or any other national securities exchange on which the shares of Class A Common Stock are then traded (“VWAP”) is greater than or equal to $15.00 over any 20 trading days within any 30 trading day period, and (ii) an additional 1,000,000 shares of Class A Common Stock, in the aggregate, if, after Closing, the VWAP is greater than or equal to $20.00 over any 20 trading days within any 30 trading day period. These 2,000,000 shares of Class A Common Stock are referred to as the “Contingency Consideration.” Subject to certain exceptions, and provided the per share value of the consideration to be received by holders of Class A Common Stock in connection with the change of control exceeds one or both of the Contingency Consideration price targets set forth above, if a change of control of New Senti occurs following the Closing, then any Contingency Consideration that remains unissued as of immediately prior to the consummation of such change of control will immediately become payable and the former holders of shares of Senti preferred stock and Senti common stock will be entitled to receive the unissued Contingent Consideration prior to the consummation of such change of control.

In connection with the Business Combination, certain related agreements have been, or will be entered into on or prior to the closing of the Business Combination (as amended), including the Subscription Agreements, the

Subject to the immediately preceding sentence and in the event that all conditions in the Subscription Agreements have been satisfied, DYNS shall use its reasonable best efforts to take, or to cause to be taken, all actions required, necessary or that it otherwise deems to be proper or advisable to consummate the transactions contemplated by the Subscription Agreements on the terms described therein. Without limiting the generality of the foregoing, DYNS shall give the Company prompt written notice (a) of any requested amendment to any Subscription Agreement, (b) of any breach or default, to the knowledge of DYNS, by any party to any Subscription Agreement, (c) of the receipt of any written notice or other written communication from any party to any Subscription Agreement with respect to any actual, or to the knowledge of DYNS, potential, threatened or claimed expiration, lapse, withdrawal, breach, default, termination or repudiation by any party to any Subscription Agreement or any provisions of any Subscription Agreement, and (d) if DYNS does not expect to receive all or any portion of the applicable purchase price under any Investor’s Subscription Agreement in accordance with its terms.

Rowe Price Group, Inc., The Invus Group, LLC and ARK Investment Management LLC (each, an “Investor”, and collectively, the “Investors”) entered into

Non-Redemption Agreements

(each a

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

This section describes the material U.S. federal income tax considerations relevant to (i) U.S. Holders (defined below) of Senti common stock and Senti preferred stock (collectively, “Senti Capital Stock”) who exchange their Senti Capital Stock for shares of Class A Common Stock in the Business Combination, and (ii) holders of Class A Common Stock who elect to have their Class A Common Stock redeemed for cash upon the Closing of the Business Combination. This discussion applies only to holders with respect to shares of Senti Capital Stock and shares of Class A Common Stock, as the case may be, that hold such shares as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment).

This discussion is based on the Code, Treasury Regulations promulgated thereunder (whether final, temporary or proposed), judicial decisions, and published rulings and administrative pronouncements of the U.S. Internal Revenue Service (the “IRS”), in each case in effect as of the date hereof. These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect the tax consequences discussed below. No rulings have been or will be sought from the IRS concerning the tax consequences of the Business Combination, the redemption or any other related matter. Accordingly, there can be no assurance that the IRS will not take a contrary position to that discussed below regarding the tax consequences of the Business Combination or the redemption, or, if challenged, that any such contrary position would not be sustained by the courts.

The following discussion does not address the effects of other U.S. federal tax laws, such as estate and gift tax laws, net investment income tax nor does it address any tax consequences arising under applicable state, local or

non-U.S.

tax laws are not discussed.

This discussion does not address all U.S. federal income tax consequences relevant to a holder’s particular circumstances, including the impact of the Medicare contribution tax on certain net investment income. In addition, it does not address consequences relevant to holders subject to special rules, including, without limitation:

•

banks, insurance companies, and certain other financial institutions;

•

regulated investment companies and real estate investment trusts;

•

brokers, dealers or traders in securities, commodities or currencies;

•

traders in securities that elect to mark to market;

•

tax-exempt

organizations or governmental organizations;

•

persons subject to the alternative minimum tax;

•

U.S. expatriates and former citizens or long-term residents of the United States;

•

persons subject to special tax accounting rules as a result of any item of gross income with respect to Class A Common Stock, as the case may be, being taken into account in an applicable financial statement;

•

holders holding Senti Capital Stock or Class A Common Stock as a position in a “straddle,” as part of a “synthetic security” or “hedge,” as part of a “conversion transaction,” or other integrated investment or risk reduction transaction;

•

controlled foreign corporations, passive foreign investment companies, or foreign corporations with respect to which there are one or more United States stockholders within the meaning of Treasury Regulation Section 1.367(b)-3(b)(1)(ii);

•

persons that actually or constructively own 5% or more by vote or value of the outstanding shares of Senti or DYNS;

144

Table of Contents

•

S corporations, partnerships or other entities or arrangements treated as partnerships or other flow-through entities for U.S. federal income tax purposes (and investors therein);

•

U.S. Holders having a “functional currency” other than the U.S. dollar;

•

persons who hold or received Senti Capital Stock or Class A Common Stock, as the case may be, pursuant to the exercise of any employee stock option, tax-qualified retirement plan or otherwise as compensation; and

•

“qualified foreign pension funds” as defined in Section 897(l)(2) of the Code and entities all of the interests of which are held by qualified foreign pension funds.

For purposes of this discussion, a “U.S. Holder” is any beneficial owner of shares of Senti Capital Stock or Class A Common Stock, as the case may be, that is for U.S. federal income tax purposes:

•

an individual who is a citizen or resident of the United States;

•

a corporation (or other entity that is classified as a corporation for U.S. federal income tax purposes) that is created or organized in or under the laws of (1) the United States or (2) any state thereof or the District of Columbia;

•

an estate, the income of which is subject to U.S. federal income tax regardless of its source; or

•

a trust that (1) is subject to the primary supervision of a U.S. court and all substantial decisions of which are subject to the control of one or more “United States persons” (within the meaning of Section 7701(a)(30) of the Code), or (2) has a valid election in effect to be treated as a United States person for U.S. federal income tax purposes.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds Senti Capital Stock or Class A Common Stock, the tax treatment of an owner of such entity will depend on the status of the owners, the activities of the entity and certain determinations made at the owner level. Accordingly, entities and arrangements treated as partnerships for U.S. federal income tax purposes and the partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences to them of the exchange of their Senti Capital Stock for Class A Common Stock in the Business Combination or the redemption of their Class A Common Stock, as applicable.

HOLDERS OF SENTI CAPITAL STOCK OR CLASS A COMMON STOCK SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL OR

NON-U.S.

TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Material Tax Considerations of the Business Combination to U.S. Holders of Senti Capital Stock

Characterization of the Business Combination

Each of Senti and DYNS intends and expects the Business Combination to qualify as a “reorganization” within the meaning of Section 368(a) of the Code for U.S. federal income tax purposes. In the Business Combination Agreement, each of Senti and DYNS has agreed to, and to cause its affiliates to, use reasonable best efforts to qualify the Business Combination as a reorganization and neither Senti nor DYNS shall take any action, or knowingly fail to take any action, that could reasonably be expected to prevent or impede such qualification. However, the completion of the Business Combination is not conditioned on the Business Combination qualifying as a reorganization within the meaning of Section 368(a) of the Code or upon receipt of an opinion from counsel to that effect.

145

Table of Contents

Senti and DYNS do not intend to seek, and have not sought, any rulings from the IRS regarding the U.S. federal income tax consequences of the Business Combination. Accordingly, there can be no assurance that the Business Combination will constitute a reorganization within the meaning of Section 368(a) of the Code or that the IRS will not assert, or that a court will not sustain, a position contrary to the conclusions set forth below.

U.S. Federal Income Tax Consequences for U.S. Holders

If the Business Combination qualifies as a reorganization within the meaning of Section 368(a) of the Code, a U.S. Holder of Senti Capital Stock will not recognize gain or loss upon the exchange of Senti Capital Stock for Class A Common Stock pursuant to the Business Combination.

A U.S. Holder’s aggregate tax basis in the shares of Class A Common Stock received in the Business Combination in exchange for Senti Capital Stock will equal the U.S. Holder’s aggregate tax basis in the shares of Senti Capital Stock surrendered in the Business Combination, and the holding period of such shares of Class A Common Stock will include the holding period of the shares of Senti capital stock surrendered in exchange therefor.

For purposes of determining the tax bases and holding periods for shares of Class A Common Stock received in the Business Combination, U.S. Holders who acquired different blocks of Senti Capital Stock at different times or for different prices must calculate their bases and holding periods in their shares of Senti Capital Stock separately for each identifiable block of such Senti Capital Stock exchanged in the Business Combination.

A U.S. Holder that receives shares of Class A Common Stock in the Business Combination and is considered a “significant holder” will be required (1) to file a statement with the holder’s U.S. federal income tax return providing certain facts pertinent to the Business Combination, including its tax basis in, and the fair market value of, the shares of Senti Capital Stock surrendered, and (2) to retain permanent records of the facts relating to the Business Combination. A “significant holder” is a U.S. Holder of Senti Capital Stock that, immediately before the Business Combination, owned at least 1% of the outstanding Senti Capital Stock by vote or value, or securities of Senti with an aggregate tax basis of $1 million or more.

U.S. Federal Income Tax Consequences if the Business Combination Failed to Qualify as a Reorganization

If the Business Combination fails to qualify as a reorganization under Section 368(a) of the Code, a U.S. Holder of Senti Capital Stock will recognize gain equal to the difference, if any, between the fair market value of the Class A Common Stock received in exchange for the Senti Capital Stock surrendered in the Business Combination and the U.S. Holder’s adjusted tax basis in such surrendered Senti Capital Stock. Any such gain or loss will be long-term capital gain or loss if the U.S. Holder’s holding period in the Senti Capital Stock surrendered in the Business Combination exceeds one year as of the closing date of the Business Combination. Long-term capital gains of

non-corporate

taxpayers are taxed at a reduced U.S. federal income tax rate. The deductibility of capital losses is subject to limitations. In addition, a U.S. Holder’s aggregate tax basis in the shares of Class A Common Stock received in the Business Combination would equal their fair market value at the time of the closing of the Business Combination, and the U.S. Holder’s holding period of such shares of Class A Common Stock would commence the day after the closing of the Business Combination.

Information Reporting and Backup Withholding

A U.S. Holder of Senti Capital Stock may be subject to information reporting and backup withholding for U.S. federal income tax purposes on proceeds received in connection with the Business Combination. The

current backup withholding rate is 24%. Backup withholding will not apply, however, to a U.S. Holder who (i) furnishes a correct taxpayer identification number and certifies the U.S. Holder is not subject to backup withholding on IRS Form

W-9

or a substantially similar form or (ii) certifies that such U.S. Holder is otherwise

146

Table of Contents

exempt from backup withholding. U.S. Holders of shares of Senti Capital Stock should consult their tax advisors regarding their qualification for an exemption from backup withholding and the procedures for obtaining such an exemption. If a U.S. Holder does not provide a correct taxpayer identification number on IRS Form

W-9

or other proper certification, the U.S. Holder may be subject to penalties imposed by the IRS. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be refunded or allowed as a credit against a U.S. Holder’s U.S. federal income tax liability, if any, provided the required information is timely furnished to the IRS.

THIS DISCUSSION OF THE MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE BUSINESS COMBINATION TO U.S. HOLDERS OF SENTI CAPITAL STOCK IS FOR GENERAL INFORMATION PURPOSES ONLY AND IS NOT INTENDED TO BE, AND MAY NOT BE CONSTRUED AS, TAX ADVICE. HOLDERS OF SENTI CAPITAL STOCK ARE URGED TO CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX RULES, OR UNDER THE LAWS OF ANY STATE, LOCAL, FOREIGN OR OTHER TAXING JURISDICTION, OR UNDER ANY APPLICABLE TAX TREATY.

Material Tax Considerations Related to a Redemption of Class A Common Stock

Treatment of Redemption of Class A Common Stock

Redemption of Class

A Common Stock.

In the event that a holder’s Class A Common Stock is redeemed pursuant to the exercise of its redemption right in connection with the shareholder vote regarding the Business Combination Proposal the treatment of the transaction for U.S. federal income tax purposes will depend on whether the redemption qualifies as a sale of the Class A Common Stock under Section 302 of the Code. If the redemption qualifies as a sale of Class A Common Stock, U.S. Holders will be treated as described under “U.S. Holders — Taxation of Redemption Treated as an Exchange of Class A Common Stock” below and Non-U.S. Holders will be treated as described under “Non-U.S. Holders — Taxation of Redemption Treated as an Exchange of Class A Common Stock” below. If the redemption does not qualify as a sale of Class A Common Stock, U.S. Holders will be treated as receiving a corporate distribution with the tax consequences described below under “U.S. Holders — Taxation of Redemption Treated as a Distribution” and Non-U.S. Holders will be subject to the tax consequences described below under “— Non-U.S. Holders — Taxation of Redemption Treated as a Distribution” below. Whether a redemption qualifies for sale treatment will depend largely on the total number of Class A Common Stock treated as held by the holder (including any Class A Common Stock constructively owned by the holder as a result of owning warrants) relative to all of DYNS’s shares outstanding both before and after such redemption. The redemption of Class A Common Stock generally will be treated as a sale of the Class A Common Stock (rather than as a corporate distribution) if such redemption (i) is “substantially disproportionate” with respect to the holder, (ii) results in a “complete termination” of the holder’s interest in DYNS or (iii) is “not essentially equivalent to a dividend” with respect to the holder (collectively, the “302 tests”). These tests are explained more fully below.

In determining whether any of the 302 tests is satisfied, a holder takes into account not only DYNS shares actually owned by the holder, but also DYNS shares that are constructively owned by such holder under the relevant rules. A holder may constructively own, in addition to shares owned directly, shares owned by certain related individuals and entities in which the holder has an interest or that have an interest in such holder, as well as any shares the holder has a right to acquire by exercise of an option, which would generally include Class A Common Stock which could be acquired pursuant to the exercise of the warrants. In order to meet the substantially disproportionate test, the percentage of DYNS outstanding voting shares actually and constructively owned by the holder immediately following the redemption of Class A Common Stock must, among other requirements, be less than 80% of the percentage of our outstanding voting shares actually and constructively owned by the holder immediately before the redemption. There will be a complete termination of a holder’s interest if either (i) all of the DYNS shares actually and constructively owned by the holder are redeemed or

147

Table of Contents

(ii) all of the DYNS shares actually owned by the holder are redeemed and the holder is eligible to waive, and effectively waives in accordance with specific rules, the attribution of shares owned by certain family members and the holder does not constructively own any other DYNS shares. The redemption of Class A Common Stock will not be essentially equivalent to a dividend if such redemption results in a “meaningful reduction” of the holder’s proportionate interest in DYNS. Whether the redemption will result in a meaningful reduction in a holder’s proportionate interest in DYNS will depend on the particular facts and circumstances. However, the IRS has indicated in a published ruling that even a small reduction in the proportionate interest of a small minority shareholder in a publicly held corporation who exercises no control over corporate affairs may constitute such a “meaningful reduction.” A holder should consult with its own tax advisors as to the tax consequences of a redemption.

If none of the 302 tests are satisfied, then the redemption will be treated as a corporate distribution and the tax effects will be as described under “U.S. Holders — Taxation of Redemption Treated as a Distribution” and “Non-U.S. Holders — Taxation of Redemption Treated as a Distribution” below. After the application of those rules, any remaining tax basis of the U.S. Holder in the redeemed Class A Common Stock will be added to the holder’s adjusted tax basis in its remaining DYNS shares, or, if it has none, possibly to the U.S. Holder’s adjusted tax basis in its warrants or other shares constructively owned by such U.S. Holder.

U.S. Holders

Taxation of Redemption Treated as an Exchange of Class

A Common Stock

. If the redemption qualifies as an exchange of Class A Common Stock as described above under “—

Treatment of Redemption of

Class

A Common Stock

,” a U.S. Holder generally will recognize capital gain or loss in an amount equal to the difference between the amount realized and the U.S. Holder’s adjusted tax basis in the Class A Common Stock. Any such capital gain or loss generally will be long-term capital gain or loss if the U.S. Holder’s holding period for the Class A Common Stock so disposed of exceeds one year. It is unclear, however, whether the redemption rights with respect to the Class A Common Stock may suspend the running of the applicable holding period for this purpose. Long-term capital gains recognized by

non-corporate

U.S. Holders will be eligible to be taxed at reduced rates under current law. The deductibility of capital losses is subject to limitations.

Generally, the amount of gain or loss recognized by a U.S. Holder is an amount equal to the difference between (i) the sum of the amount of cash and the fair market value of any property received in such disposition and (ii) the U.S. Holder’s adjusted tax basis in its Class A Common Stock so disposed of. A U.S. Holder’s adjusted tax basis in its Class A Common Stock generally will equal the U.S. Holder’s adjusted cost less any prior distributions treated as a return of capital for U.S. federal income tax purposes.

Taxation of Redemption Treated as a Distribution

. If the redemption does not qualify as an exchange of Class A Common Stock, a U.S. Holder will generally be treated as receiving a distribution in respect of its Class A Common Stock. Such a distribution generally will be includable in a U.S. Holder’s gross income as dividend income to the extent that such distributions are paid out of our current or accumulated earnings and profits as determined under U.S. federal income tax principles. Dividends will be taxable to a corporate U.S. Holder at regular rates and will generally be eligible for the dividends-received deduction if the requisite holding period is satisfied.

For

non-corporate

U.S. Holders, if the U.S. Holder satisfies certain holding period requirements and the U.S. Holder is not under an obligation to make related payments with respect to positions in substantially similar or related property, dividends are “qualified dividend income” taxed at the preferential applicable long-term capital gain rate. It is unclear whether the redemption rights with respect to the Class A Common Stock may prevent a U.S. Holder from satisfying the applicable holding period requirements with respect to the dividends received deduction or the preferential tax rate on qualified dividend income, as the case may be. If the holding period requirements are not satisfied, then

non-corporate

U.S. Holders may be subject to tax on such dividends at regular ordinary income tax rates instead of the preferential rate that applies to qualified dividend income.

148

Table of Contents

Distributions in excess of our current or accumulated earnings and profit generally will be applied against and reduce the U.S. Holder’s basis in its Class A Common Stock (but not below zero) and, to the extent in excess of such basis, will be treated as gain from the sale or exchange of such Class A Common Stock in the manner described above under “

—Taxation of Redemption Treated as an Exchange of Class

A Common Stock.

”

U.S. Information Reporting and Backup Withholding

. Distributions with respect to the Class A Common Stock to a U.S. Holder, whether or not such distributions qualify as dividends for U.S. federal income tax purposes, and proceeds from the sale, exchange or redemption of the Class A Common Stock by a U.S. Holder generally are subject to information reporting to the IRS and possible U.S. backup withholding, unless the U.S. Holder is an exempt recipient. Backup withholding may apply to such payments if a U.S. Holder fails to furnish a correct taxpayer identification number, fails to furnish a certification of exempt status or has been notified by the IRS that it is subject to backup withholding (and such notification has not been withdrawn).

Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against a U.S. Holder’s U.S. federal income tax liability, and such holder may obtain a refund of any excess amounts withheld under the backup withholding rules by timely filing the appropriate claim for refund with the IRS and furnishing any required information.

Non-U.S.

Holders

For purposes of this discussion, a

“Non-U.S.

Holder” is any beneficial owner of Class A Common Stock that is for U.S. federal income tax purposes:

•

non-resident

alien individual;

•

a foreign corporation; or

•

a foreign estate or trust.

Redemption of Class

A Common Stock

. The characterization for U.S. federal income tax purposes of the redemption of a

Non-U.S.

Holder’s share of Class A Common Stock pursuant to the redemption provisions described in the section of this proxy statement/prospectus entitled “

Special Meeting of DYNS Stockholders — Redemption Rights

” generally will follow the U.S. federal income tax characterization of such a redemption as described under “

— Treatment of Redemption of Class

A Common Stock

” above.

Because the satisfaction of the 302 tests described above is dependent on matters of fact, withholding agents may presume, for withholding purposes, that all amounts paid to Non-U.S. Holders in connection with a redemption are treated as distributions in respect of their shares. Accordingly, a Non-U.S. Holder should expect that a withholding agent will likely withhold U.S. federal income tax on the gross proceeds payable to a Non-U.S. Holder pursuant to a redemption at a rate of 30% unless such Non-U.S. Holder is eligible for a reduced rate of withholding tax under an applicable income tax treaty and provides proper certification of its eligibility for such reduced rate (usually on an IRS Form W-8BEN or W-8BEN-E, or other applicable IRS Form W-8). Each holder should consult with its own tax advisors as to the tax consequences to it of any redemption of its Class A common stock, including its ability to obtain a refund of any amounts withheld by filing an appropriate claim for a refund with the IRS in the event that the Non-U.S. Holder is not treated as receiving a dividend under the 302 tests.

Taxation of Redemption Treated as an Exchange of Class

A Common Stock

. A

Non-U.S.

Holder generally will not be subject to U.S. federal income or withholding tax in respect of any gain realized upon the redemption of Class A Common Stock unless:

•

the gain is effectively connected with the

Non-U.S.

Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the

Non-U.S.

Holder maintains a permanent establishment in the United States to which such gain is attributable);

149

Table of Contents

•

the

Non-U.S.

Holder is a nonresident alien individual present in the United States for 183 days or more during the taxable year of the disposition and certain other requirements are met; or

•

Class A Common Stock constitutes a U.S. real property interest (“USRPI”) by reason of DYNS’s status as a U.S. real property holding corporation (“USRPHC”) for U.S. federal income tax purposes, and certain other conditions are met.

Gain described in the first bullet point above generally will be subject to U.S. federal income tax on a net income basis at the regular rates applicable to a U.S. Holder, unless an applicable tax treaty provides otherwise. A

Non-U.S.

Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected gain, as adjusted for certain items.

Gain described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty), which may be offset by U.S. source capital losses of the

Non-U.S.

Holder (even though the individual is not considered a resident of the United States), provided the

Non-U.S.

Holder has timely filed U.S. federal income tax returns with respect to such losses.

With respect to the third bullet above, DYNS believes that it is not and has not been at any time since its formation, and does not expect to be immediately after the Business Combination is completed, a USRPHC.

Non-U.S.

Holders should consult their tax advisors regarding potentially applicable income tax treaties that may provide for different rules.

Taxation of Redemption Treated as a Distribution.

If the redemption does not qualify as an exchange of Class A Common Stock, with respect to a

Non-U.S.

Holder, such holder will generally be treated as receiving a distribution in respect of Class A Common Stock. Such a distribution to the extent paid out of DYNS’s current or accumulated earnings and profits (as determined under U.S. federal income tax principles) will constitute a dividend, first, for U.S. federal income tax purposes. Amounts not treated as a dividend for U.S. federal income tax purposes will constitute a return of capital and be applied against and reduce a

Non-U.S.

Holder’s adjusted tax basis in its common stock, but not below zero, and thereafter as capital gain and will be treated as described above under “—

Non-U.S.

Holders—Taxation of Redemption Treated as an Exchange of Class

A Common Stock

.”

Subject to the discussion below on effectively connected income, dividends paid to a

Non-U.S.

Holder of Class A Common Stock will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the dividends (or such lower rate specified by an applicable income tax treaty, provided the

Non-U.S.

Holder furnishes a valid IRS

Form W-8BEN

W-8BEN-E

(or other applicable documentation) certifying qualification for the lower treaty rate). A

Non-U.S.

Holder that does not timely furnish the required documentation, but that qualifies for a reduced treaty rate, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

If dividends paid to a

Non-U.S.

Holder are effectively connected with the

Non-U.S.

Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the

Non-U.S.

Holder maintains a permanent establishment in the United States to which such dividends are attributable), the

Non-U.S.

Holder will be exempt from the U.S. federal withholding tax described above. To claim the exemption, the

Non-U.S.

Holder must furnish to the applicable withholding agent a valid IRS

Form W-8ECI,

certifying that the dividends are effectively connected with the

Non-U.S.

Holder’s conduct of a trade or business within the United States.

Any such effectively connected dividends will be subject to U.S. federal income tax on a net income basis at the regular rates. A

Non-U.S.

Holders should consult their tax advisors regarding any applicable tax treaties that may provide for different rules.

150

Table of Contents

Information Reporting and Backup Withholding.

Payments of dividends on Class A Common Stock will not be subject to backup withholding, provided the applicable withholding agent does not have actual knowledge or reason to know the holder is a United States person and the holder either certifies its

non-U.S.

status, such as by furnishing a valid IRS

Form W-8BEN,

W-8BEN-E

W-8ECI,

or otherwise establishes an exemption. However, information returns are required to be filed with the IRS in connection with any dividends on Class A Common Stock paid to the

Non-U.S.

Holder, regardless of whether any tax was actually withheld. In addition, proceeds from a sale or other taxable disposition of Class A Common Stock within the United States or conducted through certain U.S.-related brokers generally will not be subject to backup withholding or information reporting if the applicable withholding agent receives the certification described above and does not have actual knowledge or reason to know that such holder is a United States person, or the holder otherwise establishes an exemption. Proceeds from a disposition of Class A Common Stock conducted through a

non-U.S.

office of a

non-U.S.

broker generally will not be subject to backup withholding or information reporting.

Copies of information returns that are filed with the IRS may also be made available under the provisions of an applicable treaty or agreement to the tax authorities of the country in which the

Non-U.S.

Holder resides or is established. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a

Non-U.S.

Holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

Foreign Account Tax Compliance

Act

. Under Sections 1471 through 1474 of the Code (such Sections commonly referred to as “FATCA”), payments of dividends on and the gross proceeds of dispositions of common stock or warrants of a U.S. issuer paid to (i) a “foreign financial institution” (as specifically defined in the Code) or (ii) a “non-financial foreign entity” (as specifically defined in the Code) will be subject to a withholding tax (separate and apart from, but without duplication of, the withholding tax described above) at a rate of 30%, unless various U.S. information reporting and due diligence requirements (generally relating to ownership by U.S. persons of interests in or accounts with those entities) have been satisfied or an exemption from these rules applies. Under proposed Treasury Regulations, the preamble to which states that taxpayers may rely on them until final Treasury Regulations are issued, this withholding tax will not apply to the gross proceeds from the sale or disposition of New Senti Class A Common Stock. An intergovernmental agreement between the United States and an applicable foreign country may modify these requirements. If a dividend payment is both subject to withholding under FATCA and subject to the withholding tax discussed above, the withholding under FATCA may be credited against, and therefore reduce, such other withholding tax. Non-U.S. holders should consult their tax advisors regarding the possible implications of this withholding tax on their New Senti Class A Common Stock.

Anticipated Accounting Treatment of the Business Combination

Notwithstanding the legal form of the Business Combination pursuant to the Business Combination Agreement, the Business Combination will be accounted for as a reverse recapitalization in accordance with U.S. GAAP. Under this method of accounting, DYNS will be treated as the acquired company for financial reporting purposes; whereas, Senti will be treated as the accounting acquiror. In accordance with this accounting method, the Business Combination will be treated as the equivalent of Senti issuing stock for the net assets of DYNS, accompanied by a recapitalization. The net assets of DYNS will be stated at historical cost, with no goodwill or other intangible assets recorded, and operations prior to the Business Combination will be those of Senti. Senti has been determined to be the accounting acquiror for purposes of the Business Combination based on an evaluation of the following facts and circumstances:

•

Senti will control a majority of the governing body of New Senti;

•

Senti’s existing senior management team will comprise the senior management of the Combined Company; and

151

Table of Contents

•

Senti’s operations prior to the Business Combination will comprise the ongoing operations of New Senti.

Regulatory Matters

The Business Combination is not subject to any additional federal or state regulatory requirement or approval, except for the filings with the State of Delaware necessary to effectuate the Business Combination and the filing of required notifications and the expiration or termination of the required waiting periods under the HSR Act.

Required Vote of DYNS Stockholders

The approval of the Business Combination Proposal will require the affirmative vote of the holders of a majority of the shares of DYNS Common Stock cast in respect of that Proposal and entitled to vote thereon at the Special Meeting, voting together as a single class. Additionally, the Business Combination will not be consummated if DYNS has less than $5,000,001 of net tangible assets after taking into account the redemption into cash of all Public Shares properly demanded to be redeemed by Public Stockholders.

The approval of the Business Combination Proposal is a condition to the consummation of the Business Combination. If the Business Combination Proposal is not approved, the other proposals (except the Adjournment Proposal, as described below) will not be presented to the stockholders for a vote.

Recommendation of the Board

THE BOARD UNANIMOUSLY RECOMMENDS THAT DYNS STOCKHOLDERS VOTE “FOR” THE APPROVAL OF THE BUSINESS COMBINATION PROPOSAL.

The existence of financial and personal interests of one or more of DYNS’s directors may result in a conflict of interest on the part of such director(s) between what he or they may believe is in the best interests of DYNS and its stockholders and what he or they may believe is best for himself or themselves in determining to recommend that stockholders vote for the Proposals. In addition, DYNS’s directors and officers have interests in the Business Combination that may conflict with your interests as a stockholder. See the section entitled “

Proposal 1: The Business Combination Proposal — Interests of the Sponsor and DYNS’s Directors and Officers in the Business Combination

” for a further discussion of these considerations.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following unaudited pro forma condensed combined financial statements are provided to aid you in your analysis of the financial aspects of the Business Combination,

Non-Redemption

Agreement and the consummation of the PIPE Investment, which are collectively referred to as the “Transactions.”

The unaudited pro forma condensed combined financial statements are based on the DYNS historical financial statements and the Senti historical consolidated financial statements as adjusted to give effect to the Transactions. The unaudited pro forma condensed combined balance sheet gives pro forma effect to the Transactions as if they had been consummated on September 30, 2021. The unaudited pro forma condensed combined statements of operations for the nine months ended September 30, 2021 and the year ended December 31, 2020 give effect to the Transactions as if they had occurred on January 1, 2020, which is the beginning of the earliest period presented. The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2020 do not reflect the DYNS historical financial statements since DYNS inception date was March 1, 2021.

The unaudited pro forma condensed combined financial statements have been derived from and should be read in conjunction with:

•

the accompanying notes to the unaudited pro forma condensed combined financial statements;

•

the historical unaudited consolidated financial statements of Senti as of and for the nine months ended September 30, 2021 and the related notes included elsewhere in this proxy statement/prospectus;

•

the historical audited consolidated financial statements of Senti as of and for the year ended December 31, 2020 and the related notes included elsewhere in this proxy statement/prospectus; and

•

DYNS Management’s Discussion and Analysis of Financial Condition and Results of Operations,

” “

Senti Management’s Discussion and Analysis of Financial Condition and Results of Operations

,” and other financial information relating to DYNS and Senti included elsewhere in this proxy statement/prospectus.

The unaudited pro forma condensed combined financial statements present two redemption scenarios as follows:

•

Assuming No Redemptions (Scenario 1)

: This presentation assumes that no Public Stockholders exercise their right to redeem their Public Shares for their pro rata share of the Trust Account, and thus, the full amount held in the Trust Account as of the Closing is available for the Business Combination; and

•

Assuming Maximum Redemptions (Scenario 2)

: This presentation assumes that 14,308,345 Public Shares are redeemed, resulting in an aggregate cash payment of approximately $143.1 million out of the Trust Account based on an assumed redemption price of $10.00 per share. This redemption figure is derived by substracting the 8,691,655 shares that will not be redeemed by Anchor Investors (due to Non-Redemption Agreements) from the 23,000,000 Public Shares issued and outstanding as at the Record Date. After a redemption of approximately $143.1 million out of the $230.0 million Trust Account, and the $66.8 million PIPE Investment, the available cash at Closing would be approximately $153.7 million, which would satisfy the condition in the Business Combination Agreement that there be at least $150.0 million in available Closing cash. When considering this maximum redemptions scenario, you should consider that the Anchor Investors’ commitments under the Non-Redemption Agreements not to redeem or to transfer their shares of Class A Common Stock do not apply in circumstances where they are compelled to do so in connection with non-discretionary ETF or mutual fund pro rata rebalancing transfers. If one or more Anchor Investors was compelled to transfer shares of Class A Common Stock for this reason, it is possible that more than 14,308,345 Public Shares could be redeemed and that there may not be $150,000,000 in cash available at Closing. As this condition is for Senti’s benefit, it is possible that Senti could waive it prior to Closing, although there is no guarantee that it would. The redemption of more than 14,308,345 Public Shares would change some of the figures presented in the maximum redemptions scenario in the unaudited pro forma financial data which follows.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

1. Description

of the Transactions

On December 19, 2021, Senti entered into a definitive merger agreement with DYNS, a publicly traded special purpose acquisition company (“SPAC”). Under the terms of the proposed transaction, a wholly owned subsidiary of DYNS will merge with Senti at an estimated combined enterprise value of approximately $276 million. The cash components of the transaction will be funded by DYNS cash in trust of $230 million (assuming no redemptions) and a $66.8 million private placement of common stock at $10.00 per share from various accredited investors (the “PIPE Investment”). The Business Combination is expected to close on , 2022 and remains subject to customary closing conditions.

Non-Redemption

Agreement

Funds and accounts managed by Counterpoint Global (Morgan Stanley Investment Management), T. Rowe, ARK and Invus Public Equities (the “Anchor Investors”) in exchange for 965,728 new securities in DYNS, will enter into

non-redemption

agreements, pursuant to which they will agree not to redeem any of the 8,691,655 Class A common stock which they hold in DYNS. The new securities issued to the Anchor Investors at the closing of the Business Combination will be Class A common stock in DYNS, and the issuance of such shares will correspond with a simultaneous cancellation/forfeiture of an equivalent aggregate amount of Class B common stock in DYNS held by the Sponsor, such that there is no net effect on the aggregate issued share capital of DYNS. New securities will be issued to the Anchor Investors on the basis that they will each receive, in Class A common stock, 11.111% of the number of shares of Class A common stock which they hold in DYNS at the time of their entry into the

non-redemption

agreement.

2. Basis

of Pro Forma Presentation

The unaudited pro forma condensed combined financial statements were prepared in accordance with Article 11 of SEC Regulation

S-X,

as amended by the final rule, Release

No. 33-10786,

Amendments to Financial Disclosures about Acquired and Disposed Businesses

. Release

No. 33-10786

replaced the previous pro forma adjustment criteria with simplified requirements to depict the accounting for the Transactions (“Transaction Accounting Adjustments”) and present the reasonably estimable synergies and other transaction effects that have occurred or are reasonably expected to occur (“Management’s Adjustments”). Management has elected not to present Management’s Adjustments and will only be presenting Transaction Accounting Adjustments in the unaudited pro forma condensed combined financial information. The adjustments presented in the unaudited pro forma condensed combined financial statements have been identified and presented to provide relevant information necessary for an understanding of the combined company reflecting the Transactions.

The unaudited pro forma condensed combined financial statements are based on the DYNS historical financial statements, and the Senti historical consolidated financial statements as adjusted to give effect to the Transactions. The unaudited pro forma condensed combined balance sheet gives pro forma effect to the Transactions as if they had been consummated on September 30, 2021. The unaudited pro forma condensed combined statements of operations for the nine months ended September 30, 2021 and the year ended December 31, 2020 give effect to the Transactions as if they had occurred on January 1, 2020, which is the beginning of the earliest period presented.

Management has made significant estimates and assumptions in its determination of the pro forma adjustments. The pro forma adjustments reflecting the Transactions are based on certain currently available information and certain assumptions and methodologies that management believes are reasonable under the circumstances. The pro forma adjustments, which are described in the accompanying notes, may be revised as additional information becomes available and is evaluated. Therefore, it is likely that the actual adjustments will differ from the pro forma adjustments, and it is possible the difference may be material. Management believes that its assumptions and methodologies provide a reasonable basis for presenting all of the significant effects of the Transactions based on information available at this time and that the pro forma adjustments give appropriate effect to those assumptions and are properly applied in the unaudited pro forma condensed combined financial statements.

158

Table of Contents

The unaudited pro forma condensed combined financial statements do not give effect to any anticipated synergies, operating efficiencies, tax savings, or cost savings that may be associated with the Business Combination. DYNS and Senti have not had any historical relationship prior to the Business Combination. Accordingly, no pro forma adjustments were required to eliminate activities between the companies.

The unaudited pro forma condensed combined financial information presents two redemption scenarios as follows:

•

Assuming No Redemptions (Scenario 1):

This presentation assumes that no Public Stockholders exercise their right to redeem their Public Shares for their pro rata share of the Trust Account, and thus, the full amount held in the Trust Account as of the Closing is available for the Business Combination; and

•

Assuming Maximum Redemptions (Scenario 2):

This redemption figure is derived by substracting the 8,691,655 shares that will not be redeemed by Anchor Investors (due to Non-Redemption Agreements) from the 23,000,000 Public Shares issued and outstanding as at the Record Date. After a redemption of approximately $143.1 million out of the $230.0 million Trust Account, and the $66.8 million PIPE Investment, the available cash at Closing would be approximately $153.7 million, which would satisfy the condition in the Business Combination Agreement that there be at least $150.0 million in available Closing cash. When considering this maximum redemptions scenario, you should consider that the Anchor Investors’ commitments under the Non-Redemption Agreements not to redeem or to transfer their shares of Class A Common Stock do not apply in circumstances where they are compelled to do so in connection with non-discretionary ETF or mutual fund pro rata rebalancing transfers. If one or more Anchor Investors was compelled to transfer shares of Class A Common Stock for this reason, it is possible that more than 14,308,345 Public Shares could be redeemed and that there may not be $150,000,000 in cash available at Closing. As this condition is for Senti’s benefit, it is possible that Senti could waive it prior to Closing, although there is no guarantee that it would. The redemption of more than 14,308,345 Public Shares would change some of the figures presented in the maximum redemptions scenario in the unaudited pro forma financial data which follows.

Shares outstanding as presented in the unaudited pro forma condensed combined financial statements include 22,713,114 shares of New Senti Class A Common Stock to be issued to Senti stockholders, 29,465,500 shares of New Senti Class A Common Stock issued to DYNS stockholders (assuming there are no DYNS public stockholders who exercise their redemption rights) and 6,680,000 shares of New Senti Class A Common Stock issued in connection with the PIPE Investment.

Assuming no DYNS public stockholders elect to redeem their shares for cash, Senti stockholders will own approximately 39% of the shares of New Senti Class A Common Stock, DYNS public stockholders will own approximately 41% of the shares of New Senti Class A Common Stock, the PIPE Investors will own approximately 11% of the shares of New Senti Class A Common Stock, and the Sponsor will own approximately 9% of the shares of New Senti Class A Common Stock, based on the number of New Senti Class A Common Stock outstanding as of September 30, 2021.

If 14,308,345 DYNS Class A Common Stock are redeemed for cash, which assumes the maximum redemption of DYNS Class A Common Stock, Senti stockholders will own approximately 51% of the shares of New Senti Class A Common Stock, DYNS public stockholders will own approximately 22% of the shares of New Senti Class A Common Stock, the PIPE Investors will own approximately 15% of the shares of New Senti Class A Common Stock, and the Sponsor will own approximately 12% of the shares of New Senti Class A Common Stock, based on the number of New Senti Class A Common Stock outstanding as of September 30, 2021.

3.	Accounting for the Merger

The Business Combination represents a reverse merger and will be accounted for as a reverse recapitalization in accordance with U.S. GAAP. Although DYNS is the legal acquirer, under this method of accounting, DYNS will be treated as the “acquired” company for financial reporting purposes. This determination is primarily based on: (1) subsequent to the Business Combination, Senti will comprise all of the ongoing operations of New Senti, (2) Senti will control a majority of the governing body of New Senti, and (3) Senti senior management will comprise all of the senior management of New Senti. Accordingly, Senti is the accounting acquirer for accounting purposes, and the Business Combination will be treated as the equivalent of Senti issuing shares for the net assets of DYNS, accompanied by a recapitalization. The net assets of Senti will be stated at historical cost. No goodwill or other intangible assets will be recorded. Operations after the Business Combination will be those of Senti.

4.	DYNS Class A Common Stock Issued to Senti Stockholders upon Closing of the Business Combination and the consummation of the PIPE Investment

Based on 117,222,508 shares of Senti Common Stock outstanding after conversion of the preferred stock into common stock and immediately prior to the closing of the Transactions, the estimated Exchange Ratio determined in accordance with the terms of the Merger Agreement is approximately 0.1938, which means New Senti expects to issue approximately 22,713,114 shares of New Senti Common Stock in the Business Combination, determined as follows:


	Number of Senti shares as of September 30, 2021
Common stock		15,002,159
Unvested restricted common stock subject to repurchase		2,485,806
Preferred stock		99,734,543

Total		117,222,508

Senti preferred and common stock outstanding prior to the closing of the Transactions		117,222,508
Assumed Exchange Ratio		0.1938

Estimated shares of New Senti common stock issued to Senti Stockholders upon closing of the Transactions		22,713,114

5.	Adjustments to Unaudited Pro Forma Condensed Combined Balance Sheet

The pro forma notes and adjustments, based on preliminary estimates that could change materially as additional information is obtained, are as follows:

Pro forma notes:

(A)

Derived from the unaudited condensed consolidated balance sheet of DYNS as of September 30, 2021.

(B)

Derived from the unaudited consolidated balance sheet of Senti as of September 30, 2021.

Pro forma Transaction Accounting Adjustments:

To reflect the release of investments from the trust account to cash and cash equivalents, assuming no DYNS public stockholders exercise their right to have their DYNS Class A Common Stock redeemed for their pro rata share of the trust account.

To reflect the payment of DYNS’s deferred underwriting fee payable of $7.1 million of costs incurred in connection with the DYNS initial public offering and is payable upon completion of the Business Combination. The payment of $7.1 million has been recorded as a reduction of $8.1 million to deferred underwriting fee payable and a corresponding $1.0 million adjustment to accumulated deficit as a result of a concession agreed with J.P Morgan Securities LLC on December 17, 2021.

To reflect the payment of accrued expenses and other current liabilities of $33 thousand and franchise taxes of $95 thousand and a reclassification of deferred transaction cost of $0.7 million that are deemed to be direct and incremental costs of the Business Combination from prepaid expenses to additional

paid-in

capital.

To reflect the payment of DYNS total estimated advisory, legal, accounting and auditing fees and other professional fees of $7.4 million that are deemed to be direct and incremental costs of the Business Combination. The payment of $7.4 million of costs directly attributable to the Business Combination have been recorded as a reduction of $7.4 million to additional

paid-in

capital.

To reflect the payment of Senti total estimated advisory, legal, accounting and auditing fees and other professional fees of $4.7 million that are deemed to be direct and incremental costs of the Business Combination. The payment of $4.7 million of costs directly attributable to the Business Combination have been recorded as a reduction of $4.7 million to additional

paid-in

capital.

To reflect the issuance of an aggregate of 6,680,000 shares of New Senti Common Stock in the PIPE Investment at a price of $10.00 per share, for proceeds of $66.8 million and to record the fees associated with the consummation of the PIPE Investment in the amount of $2.7 million.

To reflect the reclassification of Class A Common Stock subject to redemption of $230.0 million to New Senti Class A Common Stock of $2 thousand and additional paid-in capital $230.0 million, in Scenario 1, which assumes no DYNS public stockholders exercise their redemption rights.

To reflect, in Scenario 2, the assumption that DYNS public stockholders exercise their redemption rights with respect to a maximum of 14,308,345 DYNS Class A Common Stock prior to the consummation of the Business Combination at a redemption price of approximately $10.00 per share, or $143.1 million in cash. The maximum number of shares of 14,308,345 DYNS Class A Common Stock will result in a cash balance of $153.7 million that would allow the minimum cash condition in the Merger Agreement of $150.0 million to be satisfied.

To reflect the recapitalization of Senti through the contribution of all outstanding common stock and preferred stock of Senti to DYNS and the issuance of 22,713,114 shares of New Senti Class A Common Stock and the elimination of the accumulated deficit of DYNS, the accounting acquiree. As a result of the recapitalization, Senti Common Stock of $1 thousand, Senti redeemable convertible

161

Table of Contents

preferred stock of $171.8 million and DYNS accumulated deficit of $15.2 million were derecognized. The shares of New Senti Common Stock issued in exchange for Senti’s capital were recorded as increase to common stock of $2 thousand and increase to additional

paid-in

capital in amount of $156.7 million.

To reflect the cancelation of 965,728 Class B common stock of DYNS in order to issue 965,728 Class A common stock of DYNS to the Anchor Investors as discussed in Note 1 above and Note 5(k) below.

To reflect the issuance 965,728 Class A Common Stock of DYNS to the Anchor Investors. To induce Anchor Investors, to not exercise their redemption rights in respect of the Class A Common Stock in connection with the pending merger with Senti, DYNS entered into the

non-redemption

agreements with Anchor Investors. Pursuant to the

non-redemption

agreements, concurrently with the execution of the Merger Agreement, the Sponsor will agree to forfeit to DYNS certain Class B Common Stock which it holds, and DYNS will agree to cancel such Class B Common Stock of the Sponsor and concurrently issue to the Anchor Investors an equivalent number of shares of Class A Common Stock. Based on the price of $10.00 per share this transaction results in an increase to common stock of $97, increase to additional

paid-in

capital of $9.7 million and increase to accumulated deficit of $9.7 million (see note 6(e) below).

To reflect the conversion of DYNS Class B Common Stock to DYNS Class A Common Stock remaining after cancellation discussed in note 5(j) to DYNS Class A Common Stock.

To reflect the reclassification of DYNS Class A Common Stock including amounts discussed in note 5(k) to New Senti Class A Common Stock.

(A)

Derived from the unaudited condensed consolidated statement of operations of DYNS for the period from March 1, 2021 (inception) through September 30, 2021.

(B)

Derived from the unaudited consolidated statement of operations of Senti for the nine months ended September 30, 2021.

(C)

To reflect an adjustment to eliminate the change in preferred stock tranche liability as it is assumed that the preferred stock would have been converted to Senti Common Stock and then to shares of New Senti Common Stock as if the Business Combination had occurred on January 1, 2020.

To reflect an estimated compensation expense associated with the stock options that were granted under new equity incentive plan as if the Business Combination had occurred on January 1, 2020. The compensation expense was estimated on a

tranche-by-tranche

basis, using an estimated grant date fair

Table of Contents

value as of December 20, 2021. Certain Senti executives agreed to forfeit certain stock options granted to them at the time the Business Combination Agreement was signed depending on the level of redemptions of DYNS Class A Common Stock at Closing. The number of stock options under two redemption scenarios are presented as follows:


	Number of stock options under the new equity incentive plan
	Scenario 1 Assuming No Redemptions for Cash		Scenario 2 Assuming Maximum Redemptions for Cash
Stock options that are contingent on the consummation of the Business Combination and a four-year service period		42,927,654		35,627,801
Stock options that are contingent on the consummation of the Business Combination, market conditions, and an estimated two-year service period		3,093,776		1,564,391

To reflect expense associated with the issuance of the Class A Common Stock equal to $9.7 million in accordance with the

non-redemption

agreements (see notes 5(j) and 5(k) above).

The pro forma basic and diluted net loss per share amounts presented in the unaudited pro forma condensed combined statements of operations are based upon the number of New Senti shares outstanding as if the Transactions occurred on January 1, 2020. The calculation of weighted average shares outstanding for pro forma basic and diluted net loss per share assumes that the shares issuable in connection with the Transactions have been outstanding for the entirety of the periods presented.

Pro forma weighted-average common shares outstanding—basic and diluted is calculated as follows:


	Nine Months Ended September 30, 2021
	Scenario 1 (Assuming No Redemptions for Cash)			Scenario 2 (Assuming Maximum Redemptions for Cash)
Weighted-average shares calculation—basic and diluted
New Senti Class A common stock owned by Sponsors		5,499,772			5,499,772

Issuance of New Senti Class A common stock in connection with closing of the
PIPE Investment		6,680,000			6,680,000
Issuance of New Senti Class A common stock to Senti stockholders in connection with Business Combination		22,713,114			22,713,114

PROPOSAL 2: THE CHARTER AMENDMENT PROPOSAL

The Charter Amendment Proposal, if approved, will approve the following amendments to the Current Charter to:

•

change the name of the new public entity to “Senti Biosciences, Inc.” as opposed to “Dynamics Special Purpose Corp.”;

•

increase DYNS’s capitalization so that it will have authorized shares of a single class of common stock and authorized shares of preferred stock, as opposed to DYNS having 100,000,000 authorized shares of Class A Common Stock, 10,000,000 authorized shares of Class B Common Stock and 1,000,000 authorized shares of preferred stock;

•

require that the removal of any director be only for cause and by the affirmative vote of at least 75% of the Combined Company’s then-outstanding shares of capital stock entitled to vote generally in the election of directors;

•

require that certain amendments to provisions of the Proposed Charter will require the approval of at least 75% of the Combined Company’s then-outstanding shares of capital stock entitled to vote on such amendment and of each class entitled to vote thereon as a class;

•

remove the provision allowing stockholders to act by written consent in lieu of holding a meeting of stockholders; and

•

make the Combined Company’s corporate existence perpetual instead of requiring DYNS to be dissolved and liquidated 24 months following the Initial Public Offering and to remove from the Proposed Charter the various provisions applicable only to special purpose acquisition companies.

In the judgment of the Board, the Charter Amendment Proposal is desirable for the following reasons:

•

the name of the new public entity is desirable to reflect the Business Combination with Senti and the combined business going forward;

•

the greater number of authorized number of shares of capital stock is desirable for the Combined Company to have enough additional authorized shares for financing its business, for acquiring other businesses, for forming strategic partnerships and alliances and for stock dividends and stock splits and to issue upon exercise of equity grants currently outstanding or made under the Incentive Plan (assuming it is approved at the Special Meeting);

•

the single class of common stock is desirable because all shares of Class B Common Stock will be exchanged for Class A Common Stock upon consummation of the Business Combination, and because it will allow the Combined Company to have a streamlined capital structure;

•

it is desirable to increase the voting threshold required to remove a director from the Combined Company board and amend certain provisions of the Current Charter, and to remove the provision allowing stockholder action by written consent, in order to help facilitate corporate governance stability by requiring broad stockholder consensus to effect corporate governance changes, protect minority stockholder interests and enable the Combined Company board to preserve and maximize value for all stockholders in the context of an opportunistic and unsolicited takeover attempt; and

•

it is desirable to delete the provisions that relate to the operation of DYNS as a blank check company prior to the consummation of its initial business combination because they would not be applicable after the Business Combination (such as the obligation to dissolve and liquidate if a business combination is not consummated within a certain period of time).

management, which may adversely affect the market price of New Senti’s securities. If, in the due exercise of its fiduciary obligations, for example, the board of New Senti was to determine that a takeover proposal was not in the best interests of New Senti, such shares could be issued by the board without stockholder approval in one or more private placements or other transactions that might prevent or render more difficult or make more costly the completion of any attempted takeover transaction by diluting voting or other rights of the proposed acquiror or insurgent stockholder group, by creating a substantial voting bloc in institutional or other hands that might support the position of the incumbent board of directors, by effecting an acquisition that might complicate or preclude the takeover, or otherwise. The authorization of additional shares will, however, enable New Senti to have the flexibility to authorize the issuance of shares in the future for financing its business, acquiring other businesses, forming strategic partnerships and alliances and stock dividends and stock splits. DYNS currently has no such plans, proposals or arrangements, written or otherwise, to issue any of the additional authorized shares for such purposes.

Under the Business Combination Agreement, the approval of the Charter Amendment Proposal is a condition to the adoption of the Business Combination Proposal and vice versa. Accordingly, if the Business Combination Proposal is not approved, each of the Charter Amendment Proposals will not be presented at the Special Meeting.

The approval of the Charter Amendment Proposal requires the affirmative vote of a majority of the issued and outstanding shares of each of the Class A Common Stock and Class B Common Stock, voting separately, as well as the vote of a majority of the issued and outstanding shares of Class A Common Stock and Class B Common Stock, voting together as a single class. Accordingly, a DYNS stockholder’s failure to vote by proxy or to vote in person (which would include presence at a virtual meeting) at the Special Meeting or an abstention will have the same effect as a vote “AGAINST” the Charter Amendment Proposal.

A copy of the Proposed Charter, as will be in effect assuming approval of all of the Charter Amendment Proposal and upon consummation of the Business Combination and filing with the Delaware Secretary of State, is attached to this proxy statement/prospectus as

Recommendation of the Board

THE BOARD UNANIMOUSLY RECOMMENDS THAT DYNS STOCKHOLDERS VOTE “FOR” THE APPROVAL OF THE CHARTER AMENDMENT PROPOSAL.

The existence of financial and personal interests of one or more of DYNS’s directors may result in a conflict of interest on the part of such director(s) between what he, she or they may believe is in the best interests of DYNS and its stockholders and what he, she or they may believe is best for himself, herself or themselves in determining to recommend that stockholders vote for the Proposals. In addition, DYNS’s directors and officers have interests in the Business Combination that may conflict with or be in addition to your interests as a stockholder. See the section entitled “

Proposal 1: The

Business Combination Proposal — Interests of the Sponsor and DYNS’s Directors and Officers in the Business Combination

PROPOSAL 3: THE ADVISORY CHARTER AMENDMENT PROPOSALS

In connection with the Business Combination, DYNS is asking its stockholders to vote upon, on a

non-binding advisory

basis, proposals to approve certain governance provisions contained in the Proposed Charter. This separate vote is not otherwise required by Delaware law separate and apart from the Charter Amendment Proposal. Pursuant to SEC guidance, DYNS is submitting these provisions to its stockholders separately for approval, allowing stockholders the opportunity to present their separate views on important governance provisions. However, the stockholder votes regarding these proposals are advisory votes, and are not binding on DYNS or the Board (separate and apart from the approval of the Charter Amendment Proposal). In the judgment of the Board, these provisions are necessary to adequately address the needs of the Combined Company. Furthermore, the Business Combination is not conditioned on the separate approval of the Advisory Charter Amendment Proposals (separate and apart from approval of the Charter Amendment Proposal).

DYNS stockholders will be asked to approve, on a

non-binding advisory

basis, the following material differences between the Proposed Charter and the Current Charter, which are being presented as [seven] separate

sub-proposals

(the “Advisory Charter Amendment Proposals”):

•

Advisory Charter Proposal A — to change the corporate name of the Combined Company to “Senti Biosciences Inc.” on and from the time of the Business Combination;

•

Advisory Charter Proposal B — to increase the authorized shares of common stock of the Combined Company to shares;

•

Advisory Charter Proposal C — to increase the authorized shares of preferred stock that the Combined Company’s board of directors could issue to shares;

•

to provide that the removal of any director be only for cause and by the affirmative vote of at least 75% of the Combined Company’s then-outstanding shares of capital stock entitled to vote generally in the election of directors;

•

Advisory Charter Proposal E — to provide that certain amendments to provisions of the Proposed Charter will require the approval of at least 75% of the Combined Company’s then-outstanding shares of capital stock entitled to vote on such amendment [and of each class entitled to vote thereon as a class;

•

Advisory Charter Proposal F — to make the Combined Company’s corporate existence perpetual instead of requiring DYNS to be dissolved and liquidated 24 months following the closing of the Initial Public Offering, and to remove from the Proposed Charter the various provisions applicable only to special purpose acquisition companies; and

•

Advisory Charter Proposal G — to remove the provision that allows stockholders to act by written consent as opposed to holding a stockholders meeting.

Reasons for the Charter Amendments

In the judgment of the Board, the amendments to the Current Charter are desirable for the following reasons:

•

the name of the new public entity is desirable to reflect the Business Combination with Senti and the combined business going forward;

166

Table of Contents

•

the greater number of authorized number of shares of capital stock is desirable for the Combined Company to have enough additional authorized shares for financing its business, for acquiring other businesses, for forming strategic partnerships and alliances and for stock dividends and stock splits and to issue upon exercise of the equity grants currently outstanding or made under the Incentive Plan (assuming it is approved at the Special Meeting);

•

Notwithstanding the foregoing, certain of the Proposed Charter amendments may make it more difficult or to discourage an attempt to obtain control of New Senti and thereby protect continuity of or entrench its management, which may adversely affect the market price of New Senti’s securities. If, in the due exercise of its fiduciary obligations, for example, the board of New Senti was to determine that a takeover proposal was not in the best interests of New Senti, such shares could be issued by the board without stockholder approval in one or more private placements or other transactions that might prevent or render more difficult or make more costly the completion of any attempted takeover transaction by diluting voting or other rights of the proposed acquiror or insurgent stockholder group, by creating a substantial voting bloc in institutional or other hands that might support the position of the incumbent board of directors, by effecting an acquisition that might complicate or preclude the takeover, or otherwise. The authorization of additional shares will, however, enable New Senti to have the flexibility to authorize the issuance of shares in the future for financing its business, acquiring other businesses, forming strategic partnerships and alliances and stock dividends and stock splits. DYNS currently has no such plans, proposals or arrangements, written or otherwise, to issue any of the additional authorized shares for such purposes.

The approval of each of the Advisory Charter Amendment Proposal requires the affirmative vote of the holders of a majority of the shares of DYNS Common Stock cast in respect of the relevant Proposal and entitled to vote thereon at the Special Meeting, voting together as a single class.

PROPOSAL 4: THE NASDAQ STOCK ISSUANCE PROPOSAL

For purposes of complying with Rule 5635(a), (b) and (d) of the Nasdaq Stock Market Listing Rules, stockholders of DYNS are being asked to approve the issuance of up to 26,000,000 shares of Class A Common Stock in connection with the Business Combination and the issuance of an aggregate of 6,680,000 shares of Class A Common Stock to the PIPE Investors pursuant to the Subscription Agreements.

Under Nasdaq Rule 5635(a), stockholder approval is required prior to the issuance of securities in connection with the acquisition of another company if such securities are not issued in a public offering and (i) have, or will have upon issuance, voting power equal to or in excess of 20% of the voting power outstanding before the issuance of common stock (or securities convertible into or exercisable for common stock); or (ii) the number of shares of common stock to be issued is or will be equal to or in excess of 20% of the number of shares of common stock outstanding before the issuance of the stock or securities. Collectively, the Business Combination Consideration and the Contingency Consideration (which together comprise 26,000,000 shares of Class A Common Stock), and the shares being issued to the PIPE Investors, will exceed 20% or more of the outstanding DYNS Common Stock and 20% or more of the voting power, in each case outstanding before the issuance of such shares in connection with the Business Combination and the PIPE Investment.

Under Nasdaq Rule 5635(b), stockholder approval is required when any issuance or potential issuance will result in a “change of control” of the issuer. Although Nasdaq has not adopted any rule on what constitutes a “change of control” for purposes of Rule 5635(b), Nasdaq has previously indicated that the acquisition of, or right to acquire, by a single investor or affiliated investor group, as little as 20% of the common stock (or securities convertible into or exercisable for common stock) or voting power of an issuer could constitute a change of control. Under Nasdaq Rule 5635(b), the issuance of the Business Combination Consideration and the Contingency Consideration and/or the shares in the PIPE Investment will result in a “change of control” of DYNS.

Under Nasdaq Listing Rule 5635(d), stockholder approval is required for a transaction other than a public offering involving the sale, issuance or potential issuance by an issuer of common stock (or securities convertible into or exercisable for common stock) at a price that is less than the lower of (i) the closing price immediately preceding the signing of the binding agreement or (ii) the average closing price of the common stock for the five trading days immediately preceding the signing of the binding agreement, if the number of shares of common stock (or securities convertible into or exercisable for common stock) to be issued equals 20% or more of the common stock, or 20% or more of the voting power, outstanding before the issuance. Because shares of Class A Common Stock will be issued in exchange for all of the equity interests of Senti, the deemed issuance price of the shares of Class A Common Stock may be less than the lower of (i) the closing price immediately preceding the signing of the Business Combination Agreement or (ii) the average closing price of the Class A Common Stock for the five trading days immediately preceding the signing of the Business Combination Agreement. If the Business Combination Proposal is approved, the issuance of the shares of Class A Common Stock will exceed 20% of the shares of DYNS Common Stock currently outstanding. Because the issuance price may be deemed to be below the lower of (i) the closing price immediately preceding the signing of the Business Combination Agreement or (ii) the average closing price of the Class A Common Stock for the five trading days immediately preceding the signing of the Business Combination Agreement, the Nasdaq Rules may require that DYNS obtain stockholder approval of the issuance of the shares of Class A Common Stock in connection with the consummation of the Business Combination.

In addition, because the shares of Class A Common Stock issuable to the PIPE Investors (1) will be issued at a price that is less than the lower of (i) the closing price immediately preceding the signing of the Business Combination Agreement or (ii) the average closing price of the Class A Common Stock for the five trading days immediately preceding the signing of the Business Combination Agreement, and (2) will constitute more than 20% of the outstanding shares of DYNS Common Stock and more than 20% of outstanding voting power of DYNS Common Stock prior to such issuance, DYNS is required to obtain stockholder approval of such issuance pursuant to Nasdaq Rule 5635(d).

PROPOSAL 5: THE DIRECTOR ELECTION PROPOSAL

Election of Directors

At the Special Meeting, it is proposed that seven directors will be elected to be the directors of New Senti upon consummation of the Business Combination. The Combined Company’s board of directors will reclassify. The term of office of the Class I directors will expire at the first annual meeting of stockholders following the initial reclassification of the board of directors and Class I directors will be elected for a full term of three years. At the second annual meeting of stockholders following such reclassification, the term of office of the Class II directors will expire and Class II directors will be elected for a full term of three years. At the third annual meeting of stockholders following such reclassification, the term of office of the Class III directors will expire and Class III directors will be elected for a full term of three years. At each succeeding annual meeting of stockholders, directors will be elected for a full term of three years to succeed the directors of the class whose terms expire at such annual meeting. Subject to any limitations imposed by applicable law and subject to the special rights of the holders of any series of preferred stock to elect directors, any vacancy occurring in the New Senti Board for any reason, and any newly created directorship resulting from any increase in the authorized number of directors, will, unless (a) New Senti’s board of directors determines by resolution that any such vacancies or newly created directorships will be filled by the stockholders, or (b) as otherwise provided by law, be filled only by the affirmative vote of a majority of the directors then in office, even if less than a quorum, or by a sole remaining director, and not by the stockholders.

It is proposed that the Company’s board of directors consist of the following directors:

•

Class I directors: , , and .

•

Class II directors: , , and .

•

Class III directors: , , and .

Information regarding each nominee is set forth in the section entitled “

Management of the Combined Company

.”

Under Delaware law, the election of directors requires a plurality vote of the shares of DYNS Class B

Common Stock cast in respect of that Proposal and entitled to vote thereon at the Special Meeting. “Plurality” means that the individuals who receive the largest number of votes cast “FOR” are elected as directors. Consequently, any shares not voted “FOR” a particular nominee (whether as a result of an abstention, a direction to withhold authority or a broker

non-vote)

will not be counted in the nominee’s favor.

Unless authority is withheld or the shares are subject to a broker

non-vote,

the proxies solicited by the Board will be voted “FOR” the election of these nominees. In case any of the nominees becomes unavailable for election to the board of directors, an event that is not anticipated, the persons named as proxies, or their substitutes, will have full discretion and authority to vote or refrain from voting for any other candidate in accordance with their judgment.

If the Business Combination Proposal is not approved, the Director Election Proposal will not be presented at the Special Meeting.

Following consummation of the Business Combination, the election of directors of the Combined Company will be governed by the Proposed Charter, the Bylaws and the laws of the State of Delaware.

Recommendation of the Board

THE BOARD UNANIMOUSLY RECOMMENDS THAT DYNS STOCKHOLDERS VOTE “FOR” EACH OF THE NOMINEES LISTED IN THIS PROXY STATEMENT/PROSPECTUS.

PROPOSAL 6: THE INCENTIVE PLAN PROPOSAL

Overview

In this Incentive Plan Proposal, DYNS is asking its stockholders to approve the Incentive Plan. DYNS’s board of directors will adopt the Incentive Plan prior to the special meeting, in substantially the form of

Annex

attached hereto, subject to stockholder approval at the special meeting. If stockholders approve this proposal, the Incentive Plan will become effective on the consummation of the Business Combination.

The Incentive Plan is intended to replace the Senti Biosciences, Inc. 2016 Stock Incentive Plan (the “2016 Plan”). Following the Business Combination, no additional stock awards will be granted under the 2016 Plan, although all outstanding stock options granted under the 2016 Plan immediately prior to the Business Combination will be assumed by DYNS (the “Rollover Options”) and continue to be subject to the terms and conditions as set forth in the agreements evidencing such stock options and the terms of the 2016 Plan (subject to conversion based on the Exchange Ratio, except for terms rendered imperative by the Business Combination).

General Information

The purpose of the Incentive Plan is to provide a means whereby New Senti can secure and retain the services of employees, directors and consultants, to provide incentives for such persons to exert maximum efforts for the success of New Senti and its affiliates and to provide a means by which such persons may be given an opportunity to benefit from increases in value of New Senti common stock through the granting of awards under the Incentive Plan.

Approval of the Incentive Plan by DYNS’s stockholders is required, among other things, in order to comply with stock exchange rules requiring stockholder approval of equity compensation plans and allow the grant of incentive stock options (“ISOs”) under the Incentive Plan. If this Incentive Plan Proposal is approved by DYNS’s stockholders, the Incentive Plan will become effective as of the date of the closing of the Business Combination. In the event that the stockholders do not approve this proposal, the Incentive Plan will not become effective.

New Senti’s equity compensation program, as implemented under the Incentive Plan, will allow New Senti to be competitive with comparable companies in its industry by giving it the resources to attract and retain talented individuals to achieve its business objectives and build stockholder value. It is critical to New Senti’s long-term success that the interests of employees and other service providers are tied to its success as “owners” of the business. Approval of the Incentive Plan will allow New Senti to grant stock options and other equity awards at levels it determines to be appropriate in order to attract new employees and other service providers, retain existing employees and service providers and to provide incentives for such persons to exert maximum efforts for New Senti’s success and ultimately increase stockholder value. The Incentive Plan allows New Senti to utilize a broad array of equity incentives with flexibility in designing equity incentives, including traditional stock option grants, stock appreciation rights, restricted stock awards, restricted stock unit awards, other stock awards and performance awards to offer competitive equity compensation packages in order to retain and motivate the talent necessary for New Senti.

If the request to approve the Incentive Plan is approved by DYNS’ stockholders, there will be shares available for grant under the Incentive Plan as of the effective time. In addition, as further described below under “

—Description of the Incentive Plan—Authorized Shares

,” the share reserve is subject to annual increases each January 1 of up to 5% of shares of New Senti common stock (or a lesser number determined by New Senti’s board of directors). The DYNS board of directors believes this pool size is necessary to provide sufficient reserved shares for a level of grants that will attract, retain, and motivate employees and other participants.

Description of the Incentive Plan

A summary description of the material features of the Incentive Plan is set forth below. The following summary does not purport to be a complete description of all the provisions of the Incentive Plan and is qualified

172

Table of Contents

by reference

to the Incentive Plan, the form of which is attached to this proxy statement/prospectus as

Annex C

and incorporated by reference in its entirety. DYNS stockholders should refer to the Incentive Plan for more complete and detailed information about the terms and conditions of the Incentive Plan.

Eligibility

. Any individual who is an employee of New Senti or any of its affiliates, or any person who provides services to New Senti or its affiliates, including members of the New Senti Board, is eligible to receive awards under the Incentive Plan at the discretion of the plan administrator. If this proposal is approved by the stockholders, all of New Senti’s employees, directors and consultants will be eligible to receive awards following the closing of the Business Combination. When the Business Combination closes, New Senti is expected to have

approximately employees, non-employee directors

and consultants who will be eligible to receive awards under the Incentive Plan.

Awards

. The Incentive Plan provides for the grant of ISOs, within the meaning of Section 422 of the Code to employees, including employees of any parent or subsidiary, and for the grant of nonstatutory stock options (“NSOs”), stock appreciation rights, restricted stock awards, restricted stock unit awards, performance awards and other forms of awards to employees, directors and consultants, including employees and consultants of New Senti’s affiliates.

Authorized Shares

. Subject to adjustment as set forth in the Incentive Plan, the maximum number of shares of New Senti common stock that may be issued under the Incentive Plan shall be equal to shares of New Senti common stock, plus any shares underlying the Rollover Options that expire or terminate without being exercised or otherwise issued in full. In addition, the number of shares of New Senti common stock reserved for issuance under the Incentive Plan will automatically increase on January 1 of each year, starting on January 1, 2023 through January 1, 2032, in an amount equal to (1) 5% of the total number of shares of New Senti common stock on December 31 of the preceding year, or (2) a lesser number of shares of New Senti common stock determined by the New Senti Board prior to the date of the increase. The maximum number of shares of New Senti common stock that may be issued on the exercise of ISOs under the Incentive Plan is shares. As of the DYNS record date, the closing price of DYNS Common Stock as reported on the Nasdaq was $ per share.

Shares subject to stock awards granted under the Incentive Plan that expire or terminate without being exercised or otherwise issued in full or that are paid out in cash rather than in shares do not reduce the number of shares available for issuance under the Incentive Plan. Shares withheld under a stock award to satisfy the exercise, strike or purchase price of a stock award or to satisfy a tax withholding obligation do not reduce the number of shares available for issuance under the Incentive Plan. If any shares of New Senti common stock issued pursuant to a stock award or Rollover Option are forfeited back to or repurchased or reacquired by New Senti (1) because of the failure to vest, (2) to satisfy the exercise, strike or purchase price, or (3) to satisfy a tax withholding obligation in connection with an award, the shares that are forfeited or repurchased or reacquired will revert to and again become available for issuance under the Incentive Plan.

Non-Employee

Director Compensation Limit

. The aggregate value of all compensation granted or paid to

any non-employee

director with respect to any calendar year, including awards granted and cash fees paid to such non-employee director, will not exceed (1) $750,000 in total value or (2) if such non-employee director is first appointed or elected to New Senti’s board of directors during such calendar year, $1,000,000 in total value, in each case, calculating the value of any equity awards based on the grant date fair value of such equity awards for financial reporting purposes.

Plan Administration.

The New Senti Board, or a duly authorized committee thereof, will administer the Incentive Plan and is referred to as the “plan administrator” herein. New Senti’s board of directors (or committee thereof) may also delegate to one or more of New Senti’s officers the authority to (1) designate employees (other than officers) to receive specified stock awards and (2) determine the number of shares subject to such stock awards. Under the Incentive Plan, the New Senti Board (or an authorized delegate) has the authority to determine

173

Table of Contents

award recipients, grant dates, the numbers and types of stock awards to be granted, the applicable fair market value, and the provisions of each stock award, including the period of exercisability and the vesting schedule applicable to a stock award.

Under the Incentive Plan, the New Senti Board also generally has the authority to effect, without the approval of stockholders but with the consent of any materially adversely affected participant, (1) the reduction of the exercise, purchase, or strike price of any outstanding option or stock appreciation right; (2) the cancellation of any outstanding option or stock appreciation right and the grant in substitution therefore of other awards, cash, or other consideration; or (3) any other action that is treated as a repricing under generally accepted accounting principles (“GAAP”).

Stock Options

. ISOs and NSOs are granted under stock option agreements adopted by the plan administrator. The plan administrator determines the exercise price for stock options, within the terms and conditions of the Incentive Plan, provided that the exercise price of a stock option generally cannot be less than 100% of the fair market value of a share of New Senti common stock on the date of grant. Options granted under the Incentive Plan vest at the rate specified in the stock option agreement as determined by the plan administrator.

The plan administrator determines the term of stock options granted under the Incentive Plan, up to a maximum of 10 years. Unless the terms of an optionholder’s stock option agreement provide otherwise or as otherwise provided by the plan administrator, if an optionholder’s service relationship with New Senti or any of New Senti’s affiliates ceases for any reason other than disability, death, or cause, the optionholder may generally exercise any vested options for a period of three months following the cessation of service. This period may be extended in the event that exercise of the option is prohibited by applicable securities laws. Unless the terms of an optionholder’s stock option agreement provide otherwise or as otherwise provided by the plan administrator, if an optionholder’s service relationship with New Senti or any of New Senti’s affiliates ceases due to death, or an optionholder dies within a certain period following cessation of service, the optionholder or a beneficiary may generally exercise any vested options for a period of 18 months following the date of death. Unless the terms of an optionholder’s stock option agreement provide otherwise or as otherwise provided by the plan administrator, if an optionholder’s service relationship with New Senti or any of New Senti’s affiliates ceases due to disability, the optionholder may generally exercise any vested options for a period of 12 months following the cessation of service. In the event of a termination for cause, options generally terminate upon the termination date. In no event may an option be exercised beyond the expiration of its term.

Acceptable consideration for the purchase of New Senti common stock issued upon the exercise of a stock option will be determined by the plan administrator and may include (1) cash, check, bank draft or money order, (2) a broker-assisted cashless exercise, (3) the tender of shares of New Senti common stock previously owned by the optionholder, (4) a net exercise of the option if it is an NSO or (5) other legal consideration approved by the plan administrator.

Unless the plan administrator provides otherwise, options and stock appreciation rights generally are not transferable except by will or the laws of descent and distribution. Subject to approval of the plan administrator or a duly authorized officer, an option may be transferred pursuant to a domestic relations order.

Tax Limitations on ISOs

. The aggregate fair market value, determined at the time of grant, of New Senti common stock with respect to ISOs that are exercisable for the first time by an award holder during any calendar year under all of New Senti’s stock plans may not exceed $100,000. Options or portions thereof that exceed such limit will generally be treated as NSOs. No ISO may be granted to any person who, at the time of the grant, owns or is deemed to own stock possessing more than 10% of New Senti’s total combined voting power or that of any of New Senti’s parent or subsidiary corporations unless (1) the option exercise price is at least 110% of the fair market value of the stock subject to the option on the date of grant and (2) the term of the ISO does not exceed five years from the date of grant.

174

Table of Contents

Restricted Stock Unit Awards

. Restricted stock unit awards are granted under restricted stock unit award agreements adopted by the plan administrator. Restricted stock unit awards may be granted in consideration for any form of legal consideration (including services) that may be acceptable to the plan administrator and permissible under applicable law. A restricted stock unit award may be settled by cash, delivery of shares of New Senti common stock, a combination of cash and shares of New Senti common stock as determined by the plan administrator, or in any other form of consideration set forth in the restricted stock unit award agreement. Additionally, dividend equivalents may be credited in respect of shares covered by a restricted stock unit award. Except as otherwise provided in the applicable award agreement or by the plan administrator, restricted stock unit awards that have not vested will be forfeited once the participant’s continuous service ends for any reason.

Restricted Stock Awards

. Restricted stock awards are granted under restricted stock award agreements adopted by the plan administrator. A restricted stock award may be awarded in consideration for cash, check, bank draft or money order, services to us, or any other form of legal consideration that may be acceptable to the plan administrator and permissible under applicable law. The plan administrator determines the terms and conditions of restricted stock awards, including vesting and forfeiture terms. If a participant’s service relationship with New Senti ends for any reason, New Senti may receive any or all of the shares of New Senti common stock held by the participant that have not vested as of the date the participant terminates service with New Senti through a forfeiture condition or a repurchase right.

Stock Appreciation Rights

. Stock appreciation rights are granted under stock appreciation right agreements adopted by the plan administrator. The plan administrator determines the strike price for a stock appreciation right, which generally cannot be less than 100% of the fair market value of New Senti common stock on the date of grant. A stock appreciation right granted under the Incentive Plan vests at the rate specified in the stock appreciation right agreement as determined by the plan administrator. Stock appreciation rights may be settled in cash or shares of New Senti common stock or in any other form of payment, as determined by the plan administrator and specified in the stock appreciation right agreement.

The plan administrator determines the term of stock appreciation rights granted under the Incentive Plan, up to a maximum of 10 years. Unless the terms of a participant’s stock appreciation rights agreement provide otherwise or as otherwise provided by the plan administrator, if a participant’s service relationship with New Senti or any of its affiliates ceases for any reason other than cause, disability, or death, the participant may generally exercise any vested stock appreciation right for a period of three months following the cessation of service. This period may be further extended in the event that exercise of the stock appreciation right following such a termination of service is prohibited by applicable securities laws. Unless the terms of a participant’s stock appreciation rights agreement provide otherwise or as otherwise provided by the plan administrator, if a participant’s service relationship with New Senti or any of its affiliates, ceases due to disability or death, or a participant dies within a certain period following cessation of service, the participant or a beneficiary may generally exercise any vested stock appreciation right for a period of 12 months in the event of disability and 18 months in the event of death. In the event of a termination for cause, stock appreciation rights generally terminate immediately upon the occurrence of the event giving rise to the termination of the individual for cause. In no event may a stock appreciation right be exercised beyond the expiration of its term.

Performance Awards

. The Incentive Plan permits the grant of performance awards that may be settled in stock, cash or other property. Performance awards may be structured so that the stock or cash will be issued or paid

only following the achievement of

certain pre-established

performance goals during a designated performance period. Performance awards that are settled in cash or other property are not required to be valued in whole or in part by reference to, or otherwise based on, New Senti common stock.

The performance goals may be based on any measure of performance selected by the plan administrator. The performance goals may be based on company-wide performance or performance of one or more business units, divisions, affiliates, or business segments, and may be either absolute or relative to the performance of one or more comparable companies or the performance of one or more relevant indices. Unless specified otherwise

175

Table of Contents

by the plan administrator when the performance award is granted, the plan administrator will appropriately make adjustments in the method of calculating the attainment of performance goals as follows: (1) to exclude restructuring and/or other nonrecurring charges; (2) to exclude exchange rate effects; (3) to exclude the effects of changes to GAAP; (4) to exclude the effects of any statutory adjustments to corporate tax rates; (5) to exclude the effects of items that are “unusual” in nature or occur “infrequently” as determined under GAAP; (6) to exclude the dilutive effects of acquisitions or joint ventures; (7) to assume that any portion of New Senti’s business which is divested achieved performance objectives at targeted levels during the balance of a performance period following such divestiture; (8) to exclude the effect of any change in the outstanding shares of New Senti common stock by reason of any stock dividend or split, stock repurchase, reorganization, recapitalization, merger, consolidation, spin-off, combination or exchange of shares or other similar corporate change, or any distributions to common stockholders other than regular cash dividends; (9) to exclude the effects of stock based compensation and the award of bonuses under New Senti’s bonus plans; (10) to exclude costs incurred in connection with potential acquisitions or divestitures that are required to be expensed under GAAP; and (11) to exclude the goodwill and intangible asset impairment charges that are required to be recorded under GAAP. In addition, the New Senti Board may establish or provide for other adjustment items in the award agreement at the time the award is granted or in such other document setting forth the performance goals at the time the performance goals are established.

Other Stock Awards

. The plan administrator may grant other awards based in whole or in part by reference to New Senti common stock. The plan administrator will set the number of shares under the stock award (or cash equivalent) and all other terms and conditions of such awards.

Changes to Capital Structure

. In the event there is a specified type of change in the capital structure of New Senti, such as a stock split, reverse stock split, or recapitalization, appropriate adjustments will be made to (1) the class and maximum number of shares reserved for issuance under the Incentive Plan, (2) the class of shares by which the share reserve may increase automatically each year, (3) the class and maximum number of shares that may be issued on the exercise of ISOs and (4) the class and number of shares and exercise price, strike price, or purchase price, if applicable, of all outstanding stock awards.

Corporate Transactions

. The following applies to stock awards under the Incentive Plan in the event of a corporate transaction (as defined in the Incentive Plan), unless otherwise provided in a participant’s stock award agreement or other written agreement with New Senti or one of its affiliates or unless otherwise expressly provided by the plan administrator at the time of grant.

In the event of a corporate transaction, any stock awards outstanding under the Incentive Plan may be assumed, continued or substituted for by any surviving or acquiring corporation (or its parent company), and any reacquisition or repurchase rights held by New Senti with respect to the stock award may be assigned to New Senti’s successor (or its parent company). If the surviving or acquiring corporation (or its parent company) does not assume, continue or substitute for such stock awards, then (i) with respect to any such stock awards that are held by participants whose continuous service has not terminated prior to the effective time of the corporate transaction, or current participants, the vesting (and exercisability, if applicable) of such stock awards will be accelerated in full (or, in the case of performance awards with multiple vesting levels depending on the level of performance, vesting will accelerate at 100% of the target level) to a date prior to the effective time of the corporate transaction (contingent upon the effectiveness of the corporate transaction), and such stock awards

will terminate if not exercised (if applicable) at or prior to the effective time of the corporate transaction, and any reacquisition or repurchase rights held by New Senti with respect to such stock awards will lapse (contingent upon the effectiveness of the corporate transaction), and (ii) any such stock awards that are held by persons other than current participants will terminate if not exercised (if applicable) prior to the effective time of the corporate transaction, except that any reacquisition or repurchase rights held by New Senti with respect to such stock awards will not terminate and may continue to be exercised notwithstanding the corporate transaction.

In the event a stock award will terminate if not exercised prior to the effective time of a corporate transaction, the plan administrator may provide, in its sole discretion, that the holder of such stock award may not

176

Table of Contents

exercise such stock award but instead will receive a payment equal in value to the excess (if any) of (i) the per share amount payable to holders of New Senti common stock in connection with the corporate transaction, over (ii) any per share exercise price payable by such holder, if applicable.

Plan Amendment or Termination

. The New Senti Board has the authority to amend, suspend, or terminate the Incentive Plan at any time, provided that such action does not materially impair the existing rights of any participant without such participant’s written consent. Certain material amendments also require approval of New Senti’s stockholders. No ISOs may be granted after the tenth anniversary of the date the DYNS board of directors adopts the Incentive Plan. No stock awards may be granted under the Incentive Plan while it is suspended or after it is terminated.

U.S. Federal Income Tax Consequences

The following is a summary of the principal U.S. federal income tax consequences to participants and New Senti with respect to participation in the Incentive Plan, which will not become effective until the date of the closing of the merger. No awards will be issued under the Incentive Plan prior to the date of the closing of the merger. This summary is not intended to be exhaustive and does not discuss the income tax laws of any local, state or foreign jurisdiction in which a participant may reside. The information is based upon current U.S. federal income tax rules and therefore is subject to change when those rules change. Because the tax consequences to any participant may depend on his or her particular situation, each participant should consult the participant’s tax adviser regarding the federal, state, local and other tax consequences of the grant or exercise of an award or the disposition of stock acquired under the Incentive Plan. The Incentive Plan is not qualified under the provisions of Section 401(a) of the Code and is not subject to any of the provisions of the Employee Retirement Income Security Act of 1974, as amended. New Senti’s ability to realize the benefit of any tax deductions described below depends on New Senti’s generation of taxable income as well as the requirement of reasonableness and the satisfaction of New Senti’s tax reporting obligations.

Nonstatutory Stock Options

. Generally, there is no taxation upon the grant of a NSO. Upon exercise, a participant will recognize ordinary income equal to the excess, if any, of the fair market value of the underlying stock on the date of exercise of the stock option over the exercise price. If the participant is employed by New Senti or one of its affiliates, that income will be subject to withholding taxes. The participant’s tax basis in those shares will be equal to their fair market value on the date of exercise of the stock option, and the participant’s capital gain holding period for those shares will begin on the day after they are transferred to the participant. Subject to the requirement of reasonableness, the deduction limits under Section 162(m) of the Code and the satisfaction of a tax reporting obligation, New Senti will generally be entitled to a tax deduction equal to the taxable ordinary income realized by the participant.

Incentive Stock Option

s. The Incentive Plan provides for the grant of stock options that are intended to qualify as “incentive stock options,” as defined in Section 422 of the Code. Under the Code, a participant generally is not subject to ordinary income tax upon the grant or exercise of an ISO. If the participant holds a share received upon exercise of an ISO for more than two years from the date the stock option was granted and more than one year from the date the stock option was exercised, which is referred to as the required holding period, the difference, if

any, between the amount realized on a sale or other taxable disposition of that share and the participant’s tax basis in that share will be long-term capital gain or loss. If, however, a participant disposes of a share acquired upon exercise of an ISO before the end of the required holding period, which is referred to as a disqualifying disposition, the participant generally will recognize ordinary income in the year of the disqualifying disposition equal to the excess, if any, of the fair market value of the share on the date of exercise of the stock option over the exercise price. However, if the sales proceeds are less than the fair market value of the share on the date of exercise of the stock option, the amount of ordinary income recognized by the participant will not exceed the gain, if any, realized on the sale. If the amount realized on a disqualifying disposition exceeds the fair market value of the share on the date of exercise of the stock option, that excess will be short-term or long-term capital gain, depending on whether the holding period for the share exceeds one year. For purposes of

177

Table of Contents

the alternative minimum tax, the amount by which the fair market value of a share of stock acquired upon exercise of an ISO exceeds the exercise price of the stock option generally will be an adjustment included in the participant’s alternative minimum taxable income for the year in which the stock option is exercised. If, however, there is a disqualifying disposition of the share in the year in which the stock option is exercised, there will be no adjustment for alternative minimum tax purposes with respect to that share. In computing alternative minimum taxable income, the tax basis of a share acquired upon exercise of an ISO is increased by the amount of the adjustment taken into account with respect to that share for alternative minimum tax purposes in the year the stock option is exercised. New Senti is not allowed a tax deduction with respect to the grant or exercise of an ISO or the disposition of a share acquired upon exercise of an ISO after the required holding period. If there is a disqualifying disposition of a share, however, New Senti will generally be entitled to a tax deduction equal to the taxable ordinary income realized by the participant, subject to the requirement of reasonableness, the deduction limits under Section 162(m) of the Code and provided that either the employee includes that amount in income or New Senti timely satisfies its reporting requirements with respect to that amount.

Restricted Stock Awards

. Generally, the recipient of a restricted stock award will recognize ordinary income at the time the stock is received equal to the excess, if any, of the fair market value of the stock received over any amount paid by the recipient in exchange for the stock. If, however, the stock is subject to restrictions constituting a substantial risk of forfeiture when it is received (for example, if the employee is required to work for a period of time in order to have the right to transfer or sell the stock), the recipient generally will not recognize income until the restrictions constituting a substantial risk of forfeiture lapse, at which time the recipient will recognize ordinary income equal to the excess, if any, of the fair market value of the stock on the date it becomes vested over any amount paid by the recipient in exchange for the stock. A recipient may, however, file an election with the IRS, within 30 days following the date of grant, to recognize ordinary income, as of the date of grant, equal to the excess, if any, of the fair market value of the stock on the date the award is granted over any amount paid by the recipient for the stock. The recipient’s basis for the determination of gain or loss upon the subsequent disposition of shares acquired from a restricted stock award will be the amount paid for such shares plus any ordinary income recognized either when the stock is received or when the restrictions constituting a substantial risk of forfeiture lapse. Subject to the requirement of reasonableness, the deduction limits under Section 162(m) of the Code and the satisfaction of a tax reporting obligation, New Senti will generally be entitled to a tax deduction equal to the taxable ordinary income realized by the recipient of the restricted stock award.

Restricted Stock Unit Awards

. Generally, the recipient of a restricted stock unit award will generally recognize ordinary income at the time the stock is delivered equal to the excess, if any, of (i) the fair market value of the stock received over any amount paid by the recipient in exchange for the stock or (ii) the amount of cash paid to the participant. The recipient’s basis for the determination of gain or loss upon the subsequent disposition of shares acquired from a restricted stock unit award will be the amount paid for such shares plus any ordinary income recognized when the stock is delivered, and the participant’s capital gain holding period for those shares will begin on the day after they are transferred to the participant. Subject to the requirement of reasonableness, the deduction limits under Section 162(m) of the Code and the satisfaction of a tax reporting obligation, New Senti will generally be entitled to a tax deduction equal to the taxable ordinary income realized by the recipient of the restricted stock unit award.

Stock Appreciation Rights

. Generally, the recipient of a stock appreciation right will recognize ordinary income equal to the fair market value of the stock or cash received upon exercise. Subject to the requirement of reasonableness, the deduction limits under Section 162(m) of the Code and the satisfaction of a tax reporting obligation, New Senti will generally be entitled to a tax deduction equal to the taxable ordinary income realized by the recipient of the stock appreciation right.

Tax Consequences to New Senti

Compensation of Covered Employees

. The ability of New Senti to obtain a deduction for amounts paid under the Incentive Plan could be limited by Section 162(m) of the Code. Section 162(m) of the Code limits New

178

Table of Contents

Senti’s ability to deduct compensation, for U.S. federal income tax purposes, paid during any year to a “covered employee” (within the meaning of Section 162(m) of the Code) in excess of $1.0 million.

Golden Parachute Payments

. The ability of New Senti (or the ability of one of its subsidiaries) to obtain a deduction for future payments under the Incentive Plan could also be limited by the golden parachute rules of Section 280G of the Code, which prevent the deductibility of certain “excess parachute payments” made in connection with a change in control of an employer-corporation.

New Plan Benefits

No awards have been previously granted under the Incentive Plan and no awards have been granted that are contingent on shareholder approval of the Incentive Plan. The awards that are to be granted to any participant or group of participants are indeterminable at the date of this proxy statement/prospectus because participation and the types of awards that may be granted under the Incentive Plan are subject to the discretion of the plan administrator. Consequently, no new plan benefits table is included in this proxy statement/ prospectus.

Interests of DYNS’s Directors and Officers in the Incentive Plan Proposal

When you consider the recommendation of the DYNS board of directors in favor of approval of the Incentive Plan, you should keep in mind that certain of DYNS’s board of directors and officers have interests in the Incentive Plan that are different from, or in addition to, your interests as a stockholder because they may in the future receive awards under the Incentive Plan.

PROPOSAL 7: THE ESPP PROPOSAL

Overview

In this ESPP Proposal, DYNS is asking its stockholders to approve the ESPP. The DYNS board of directors will adopt the ESPP prior to the special meeting, in substantially the form of

Annex D

attached hereto, subject to stockholder approval at the special meeting. If stockholders approve this proposal, the ESPP will become effective on the consummation of the Business Combination. If the ESPP is not approved by the stockholders, it will not become effective. The ESPP is described in more detail below.

The purpose of the ESPP is to provide a means whereby New Senti can align the long-term financial interests of its employees with the financial interests of its stockholders. In addition, the board of directors believes that the ability to allow its employees to purchase shares of New Senti common stock will help New Senti to attract, retain, and motivate employees and encourages them to devote their best efforts to New Senti’s business and financial success. Approval of the ESPP by DYNS stockholders will allow New Senti to provide its employees with the opportunity to acquire an ownership interest in New Senti through their participation in the ESPP, thereby encouraging them to remain in service and more closely aligning their interests with those of New Senti’s stockholders. When the Business Combination closes, New Senti is expected to have approximately employees eligible to participate in the ESPP.

Description of the ESPP

The material features of the ESPP are described below. The following description of the ESPP is a summary only. This summary is not a complete statement of the ESPP and is qualified in its entirety by reference to the complete text of the ESPP, a copy of which is attached hereto as

Annex D

. DYNS stockholders should refer to the ESPP for more complete and detailed information about the terms and conditions of the ESPP.

Purpose

. The purpose of the ESPP is to provide a means by which eligible employees of New Senti and certain designated companies may be given an opportunity to purchase shares of New Senti common stock following the closing of the Business Combination, to assist New Senti in retaining the services of eligible employees, to secure and retain the services of new employees and to provide incentives for such persons to exert maximum efforts for New Senti’s success.

Share Reserve

. The maximum number of shares of New Senti common stock that may be issued under the ESPP will be equal to shares of New Senti common stock. Additionally, the number of shares of New Senti common stock reserved for issuance under the ESPP will automatically increase on January 1st of each year, beginning on January 1, 2023 and continuing through and including January 1, 2032, by the lesser of 1% of the total number of shares of New Senti common stock on December 31st of the preceding calendar year or such lesser number of shares of New Senti common stock as determined by the New Senti Board or Shares. Shares subject to purchase rights granted under the ESPP that terminate without having been exercised in full will not reduce the number of shares available for issuance under the ESPP. As of , 2022, the DYNS record date, the closing price of DYNS Common Stock as reported on the Nasdaq was $ per share.

Administration

. New Senti’s board of directors, or a duly authorized committee thereof, will administer the ESPP.

Limitations

. New Senti employees and the employees of any of its designated affiliates, will be eligible to participate in the ESPP, provided they may have to satisfy one or more of the following service requirements before participating in the ESPP, as determined by the administrator: (1) customary employment with New Senti or one of its affiliates for more than 20 hours per week and five or more months per calendar year or (2) continuous employment with New Senti or one of its affiliates for a minimum period of time, not to exceed two years, prior to the first date of an offering. In addition, New Senti Board may also exclude from participation in

180

Table of Contents

the ESPP or any offering, employees who are “highly compensated employees” (within the meaning of Section 423(b)(4)(D) of the Code) or a subset of such highly compensated employees. If this proposal is approved by the stockholders, all the employees of New Senti and its designated related corporations will be eligible to participate in the ESPP following the closing of the Business Combination. An employee may not be granted rights to purchase stock under the ESPP (a) if such employee immediately after the grant would own stock possessing 5% or more of the total combined voting power or value of all classes of New Senti’s capital stock or (b) to the extent that such rights would accrue at a rate that exceeds $25,000 worth of New Senti’s capital stock for each calendar year that the rights remain outstanding.

The ESPP is intended to qualify as an employee stock purchase plan under Section 423 of the Code. The administrator may specify offerings with a duration of not more than 27 months, and may specify one or more shorter purchase periods within each offering. Each offering will have one or more purchase dates on which shares of New Senti common stock will be purchased for the employees who are participating in the offering. The administrator, in its discretion, will determine the terms of offerings under the ESPP. The administrator has the discretion to structure an offering so that if the fair market value of a share of New Senti common stock on any purchase date during the offering period is less than or equal to the fair market value of a share of New Senti common stock on the first day of the offering period, then that offering will terminate immediately, and the participants in such terminated offering will be automatically enrolled in a new offering that begins immediately after such purchase date.

A participant may not transfer purchase rights under the ESPP other than by will, the laws of descent and distribution, or as otherwise provided under the ESPP.

Payroll Deductions

. The ESPP permits participants to purchase shares of New Senti common stock through payroll deductions. Unless otherwise determined by the administrator, the purchase price of the shares will be 85% of the lower of the fair market value of New Senti common stock on the first day of an offering or on the date of purchase.

Withdrawal.

Participants may withdraw from an offering by delivering a withdrawal form to New Senti and terminating their contributions. Such withdrawal may be elected at any time prior to the end of an offering, except as otherwise provided by the plan administrator. Upon such withdrawal, New Senti will distribute to the employee his or her accumulated but unused contributions without interest, and such employee’s right to participate in that offering will terminate. However, an employee’s withdrawal from an offering does not affect such employee’s eligibility to participate in any other offerings under the ESPP.

Termination of Employment.

A participant’s rights under any offering under the ESPP will terminate immediately if the participant either (i) is no longer employed by New Senti or any of its parent or subsidiary companies (subject to any post-employment participation period required by law) or (ii) is otherwise no longer eligible to participate. In such event, New Senti will distribute to the participant his or her accumulated but unused contributions, without interest.

Corporate Transactions

. In the event of certain specified significant corporate transactions, such as a merger or change in control, a successor corporation may assume, continue, or substitute each outstanding purchase right. If the successor corporation does not assume, continue, or substitute for the outstanding purchase rights, the offering in progress will be shortened and a new purchase date will be set. The participants’ purchase rights will be exercised on the new purchase date and such purchase rights will terminate immediately thereafter.

Amendment and Termination

. New Senti’s board of directors has the authority to amend, suspend, or terminate the ESPP, at any time and for any reason, provided certain types of amendments will require the approval of New Senti stockholders. Any benefits privileges, entitlements and obligations under any outstanding purchase rights granted before an amendment, suspension or termination of the Plan will not be materially impaired by any such amendment, suspension or termination except (i) with the consent of the person to whom such purchase rights were granted, (ii) as necessary to facilitate compliance with any laws, listing requirements,

181

Table of Contents

or governmental regulations, or (iii) as necessary to obtain or maintain favorable tax, listing, or regulatory treatment. The ESPP will remain in effect until terminated by New Senti’s board of directors in accordance with the terms of the ESPP.

U.S. Federal Income Tax Consequences

The following is a summary of the principal U.S. federal income tax consequences to participants and New Senti with respect to participation in the ESPP. This summary is not intended to be exhaustive and does not discuss the income tax laws of any local, state or foreign jurisdiction in which a participant may reside. The information is based upon current U.S. federal income tax rules and therefore is subject to change when those rules change. Because the tax consequences to any participant may depend on his or her particular situation, each participant should consult the participant’s tax adviser regarding the federal, state, local, and other tax consequences of the grant or exercise of a purchase right or the sale or other disposition of New Senti common stock acquired under the ESPP. The ESPP is not qualified under the provisions of Section 401(a) of the Code and is not subject to any of the provisions of the Employee Retirement Income Security Act of 1974, as amended.

Section 423 of the Code

Rights granted under the ESPP are intended to qualify for favorable U.S. federal income tax treatment associated with rights granted under an employee stock purchase plan which qualifies under the provisions of Section 423 of the Code.

A participant will be taxed on amounts withheld for the purchase of shares of New Senti common stock as if such amounts were actually received. Otherwise, no income will be taxable to a participant as a result of the granting or exercise of a purchase right until a sale or other disposition of the acquired shares. The taxation upon such sale or other disposition will depend upon the holding period of the acquired shares.

If the shares are sold or otherwise disposed of more than two years after the beginning of the offering period and more than one year after the shares are transferred to the participant, then the lesser of the following will be treated as ordinary income: (i) the excess of the fair market value of the shares at the time of such sale or other disposition over the purchase price; or (ii) the excess of the fair market value of the shares as of the beginning of the offering period over the purchase price (determined as of the beginning of the offering period). Any further gain or any loss will be taxed as a long-term capital gain or loss.

If the shares are sold or otherwise disposed of before the expiration of either of the holding periods described above, then the excess of the fair market value of the shares on the purchase date over the purchase price will be treated as ordinary income at the time of such sale or other disposition. The balance of any gain will be treated as capital gain. Even if the shares are later sold or otherwise disposed of for less than their fair market value on the purchase date, the same amount of ordinary income is attributed to the participant, and a capital loss is recognized equal to the difference between the sales price and the fair market value of the shares on such purchase date. Any capital gain or loss will be short-term or long-term, depending on how long the shares have been held.

New Senti is not allowed a deduction upon the grant or exercise of a purchase right or the disposition of a share acquired upon exercise of a purchase right after the required holding period. If the shares are sold or otherwise disposed of before the expiration of either holding period, New Senti will generally be entitled to a tax deduction equal to the taxable ordinary income, realized by the participant.

New Plan Benefits

Participation in the ESPP is voluntary and each eligible employee will make his or her own decision regarding whether and to what extent to participate in the ESPP. Therefore, DYNS cannot currently determine the benefits or number of shares subject to purchase rights and a new plan benefits table is thus not provided.

PROPOSAL 8: THE ADJOURNMENT PROPOSAL

The Adjournment Proposal allows the Board to submit a proposal to adjourn the Special Meeting to a later date or dates if DYNS is unable to consummate the Business Combination for any reason. In no event will DYNS solicit proxies to adjourn the Special Meeting or consummate the Business Combination beyond the date by which it may properly do so under the Business Combination Agreement or its Current Charter and Delaware law. The purpose of the Adjournment Proposal is to provide more time to consummate the Business Combination, if necessary and appropriate. See the section entitled “

Proposal 1: The Business Combination Proposal

— Interests of the Sponsor and DYNS

’

s Directors and Officers in the Business Combination

.”

In addition to an adjournment of the Special Meeting upon approval of an adjournment proposal, the Board is empowered under Delaware law to postpone the Special Meeting at any time prior to the meeting being called to order. In such event, DYNS will issue a press release and take such other steps as it believes are necessary and practical in the circumstances to inform its stockholders of the postponement.

Consequences if the Adjournment Proposal is not Approved

If the Adjournment Proposal is presented at the Special Meeting and is not approved by DYNS’s stockholders, the Board may not be able to adjourn the Special Meeting to a later date if DYNS is unable to consummate the Business Combination (because either the Business Combination Proposal is not approved or the conditions to consummating the Business Combination have not been met). In such event, the Business Combination would not be completed.

Required Vote of DYNS Stockholders

Adoption of an Adjournment Proposal requires the affirmative vote of a majority of the issued and outstanding shares of DYNS Common Stock cast by the stockholders represented in person (which would include presence at a virtual meeting) or by proxy at the Special Meeting and entitled to vote thereon. Adoption of the Adjournment Proposal is not conditioned upon the adoption of any of the other proposals.

Recommendation of the Board

THE BOARD UNANIMOUSLY RECOMMENDS THAT DYNS STOCKHOLDERS VOTE “FOR” THE APPROVAL OF THE ADJOURNMENT PROPOSAL.

Financial Position

We have funds available for an initial business combination initially in the amount of $230,000,000, after our expected payment of a maximum of $7,050,000 of deferred underwriting fees, before fees and expenses associated with our initial business combination (other than deferred underwriting fees) and before any redemptions by holders of Public Shares. We have also undertaken steps to secure third-party equity financing in an aggregate amount of $66.8 million via the PIPE Investment.

Effecting Our Initial Business Combination

Selection of a Target Business and Structuring of our Initial Business Combination

Nasdaq rules require that we must complete one or more business combinations having an aggregate fair market value of at least 80% of the value of the assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable on the interest earned on the Trust Account) at the time of our signing a definitive agreement in connection with our initial business combination. The Board determined that this test was met in connection with the proposed Business Combination.

Redemption Rights for Public Stockholders upon Completion of our Initial Business Combination

We are providing our Public Stockholders with the opportunity to redeem all or a portion of their Public Shares upon the completion of our initial business combination at a

per-share price,

payable in cash, equal to the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the initial business combination including interest earned on the funds held in the Trust Account and not previously released to us to pay our taxes, divided by the number of then outstanding Public Shares, subject to the

188

Table of Contents

limitations described herein. The amount in the Trust Account was approximately $10.00 per share as of the Record Date. The

per-share amount

we will distribute to holders of Public Shares who properly redeem their shares will not be reduced by the deferred underwriting commissions we will pay to the underwriters of our Initial Public Offering. The Sponsor and our officers and directors have entered into a letter agreement with us, pursuant to which they have agreed to waive their redemption rights with respect to their Founder Shares and Public Shares held by them in connection with the completion of our initial business combination.

Limitation on Redemption Right

Notwithstanding the foregoing, in no event will we redeem our Public Shares in an amount that would cause our net tangible assets to be less than $5,000,001.

Redemption of Public Shares and Liquidation if no Initial Business Combination

We have until May 28, 2023 to complete our initial business combination. If we are unable to complete our initial business combination by such date, we will: (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a

per-share price,

payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to us to pay our taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public Stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and our Board, dissolve and liquidate, subject in the case of clauses (ii) and (iii) above to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

The Sponsor and our officers and directors have entered into a letter agreement with us, pursuant to which they have waived their rights to liquidating distributions from the Trust Account with respect to any Founder Shares and (along with the underwriters) Private Placement Shares held by them if we fail to complete our initial business combination by May 28, 2023. However, if the Sponsor, or our officers or directors acquired Public Shares in or after the Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if we fail to complete our initial business combination within 24 months from the closing of the Initial Public Offering.

The Sponsor and our officers and directors have agreed, pursuant to a written agreement with us, that they will not propose any amendment to our Current Charter (i) to modify the substance or timing of our obligation to allow redemption in connection with our initial business combination or certain amendments to our Current Charter prior thereto or to redeem 100% of our Public Shares if we do not complete our initial business combination by May 28, 2023 or (ii) with respect to any other provision relating to stockholders’ rights or

pre-initial

business combination activity, unless we provide our Public Stockholders with the opportunity to redeem their Public Shares upon approval of any such amendment at a

per-share price,

payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to us to pay our taxes divided by the number of then outstanding Public Shares. However, we may not redeem our Public Shares unless our net tangible assets are at least $5,000,001, either immediately prior to or upon consummation of our initial business combination and after payment of underwriters’ fees and commissions (so that we are not subject to the SEC’s “penny stock” rules). If this optional redemption right is exercised with respect to an excessive number of Public Shares such that we cannot satisfy the net tangible asset requirement (described above), we would not proceed with the amendment or the related redemption of our Public Shares at such time.

189

Table of Contents

We expect that all costs and expenses associated with implementing our plan of dissolution, as well as payments to any creditors, will be funded from amounts remaining out of the approximately $1,100,000 of proceeds held outside the Trust Account, although we cannot provide any assurance that there will be sufficient funds for such purpose. We will depend on sufficient interest being earned on the proceeds held in the Trust Account to pay any tax obligations we may owe. However, if those funds are not sufficient to cover the costs and expenses associated with implementing our plan of dissolution, to the extent that there is any interest accrued in the Trust Account not required to pay taxes, we may request the trustee of the Trust Account (Continental) to release to us an additional amount of up to $3,925.00 of such accrued interest to pay those costs and expenses.

If we were to expend all of the net proceeds of the Initial Public Offering and the Concurrent Private Placement, other than the proceeds deposited in the Trust Account, and without taking into account interest, if any, earned on the Trust Account, the

per-share redemption

amount received by stockholders upon our dissolution would be approximately $10.00. The proceeds deposited in the Trust Account could, however, become subject to the claims of our creditors which would have higher priority than the claims of our Public Stockholders. We cannot provide any assurance that the actual

per-share redemption

amount received by stockholders will not be substantially less than $10.00. Under Section 281(b) of the DGCL, our plan of dissolution must provide for all claims against us to be paid in full or make provision for payments to be made in full, as applicable, if there are sufficient assets. These claims must be paid or provided for before we make any distribution of our remaining assets to our stockholders. While we intend to pay such amounts, if any, we cannot provide any assurance that we will have funds sufficient to pay or provide for all creditors’ claims.

Although we seek to have all vendors, service providers, prospective target businesses or other entities with which we do business execute agreements with us waiving any right, title, interest or claim of any kind in or to any monies held in the Trust Account for the benefit of our Public Stockholders, there is no guarantee that they will execute such agreements or even if they execute such agreements that they would be prevented from bringing claims against the Trust Account including but not limited to fraudulent inducement, breach of fiduciary responsibility or other similar claims, as well as claims challenging the enforceability of the waiver, in each case in order to gain an advantage with respect to a claim against our assets, including the funds held in the Trust Account. If any third party refuses to execute an agreement waiving such claims to the monies held in the Trust Account, our management will perform an analysis of the alternatives available to it and will only enter into an agreement with a third party that has not executed a waiver if management believes that such third party’s engagement would be significantly more beneficial to us than any alternative. Examples of possible instances where we may engage a third party that refuses to execute a waiver include the engagement of a third party consultant whose particular expertise or skills are believed by management to be significantly superior to those of other consultants that would agree to execute a waiver or in cases where management is unable to find a service provider willing to execute a waiver. Marcum LLP, our independent registered public accounting firm, has not executed agreements with us waiving such claims to the monies held in the Trust Account.

In addition, there is no guarantee that such entities will agree to waive any claims they may have in the future as a result of, or arising out of, any negotiations, contracts or agreements with us and will not seek recourse against the Trust Account for any reason. Pursuant to a letter agreement, the Sponsor has agreed that it will be liable to us if and to the extent any claims by a third party for services rendered or products sold to us, or a prospective target business with which we have entered into a written letter of intent, confidentiality or similar agreement or business combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under our indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act.

190

Table of Contents

However, we have not asked the Sponsor to reserve for such indemnification obligations, nor have we independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and believe that the Sponsor’s only assets are securities of our company. Therefore, we cannot provide any assurance that the Sponsor would be able to satisfy those obligations. None of our officers or directors will indemnify us for claims by third parties including, without limitation, claims by vendors and prospective target businesses.

In the event that the proceeds in the Trust Account are reduced below (i) $10.00 per Public Share or (ii) such lesser amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, due to reductions in value of the trust assets, in each case net of the amount of interest which may be withdrawn to pay taxes, and the Sponsor asserts that it is unable to satisfy its indemnification obligations or that it has no indemnification obligations related to a particular claim, our independent directors would determine whether to take legal action against the Sponsor to enforce its indemnification obligations. While we currently expect that our independent directors would take legal action on our behalf against the Sponsor to enforce its indemnification obligations to us, it is possible that our independent directors, in exercising their business judgment, may choose not to do so if, for example, the cost of such legal action is deemed by the independent directors to be too high relative to the amount recoverable or if the independent directors determine that a favorable outcome is not likely. We have not asked the Sponsor to reserve for such indemnification obligations and we cannot provide any assurance that the Sponsor would be able to satisfy those obligations. Accordingly, we cannot provide any assurance that due to claims of creditors the actual value of the

per-share redemption

price will not be less than $10.00 per Public Share.

We will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers [(other than our independent registered public accounting firm)], prospective target businesses or other entities with which we do business execute agreements with us waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. The Sponsor will also not be liable as to any claims under our indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act. We will have access to up to approximately $[1,100,000] from the proceeds of the Initial Public Offering and the Concurrent Private Placement with which to pay any such potential claims (including costs and expenses incurred in connection with our liquidation, currently estimated to be no more than approximately $100,000). In the event that we liquidate and it is subsequently determined that the reserve for claims and liabilities is insufficient, stockholders who received funds from our Trust Account could be liable for claims made by creditors. In the event that the Initial Public Offering expenses exceed our estimate of $[1,455,000], we may fund such excess with funds from the funds not to be held in the Trust Account. In such case, the amount of funds we intend to be held outside the Trust Account would decrease by a corresponding amount. Conversely, in the event that the Initial Public Offering expenses are less than our estimate of $[1,455,000], the amount of funds we intend to be held outside the Trust Account would increase by a corresponding amount.

Under the DGCL, stockholders may be held liable for claims by third parties against a corporation to the extent of distributions received by them in a dissolution. The pro rata portion of our Trust Account distributed to our Public Stockholders upon the redemption of our Public Shares in the event we do not complete our initial business combination by May 28, 2023 (or any stockholder-approved extension period) may be considered a liquidating distribution under Delaware law. If the corporation complies with certain procedures set forth in Section 280 of the DGCL intended to ensure that it makes reasonable provision for all claims against it, including a

60-day notice

period during which any third-party claims can be brought against the corporation, a

90-day period

during which the corporation may reject any claims brought, and an additional

150-day waiting

period before any liquidating distributions are made to stockholders, any liability of stockholders with respect to a liquidating distribution is limited to the lesser of such stockholder’s pro rata share of the claim or the amount distributed to the stockholder, and any liability of the stockholder would be barred after the third anniversary of the dissolution.

Furthermore, if the pro rata portion of our Trust Account distributed to our Public Stockholders upon the redemption of our Public Shares in the event we do not complete our initial business combination by May 28,

191

Table of Contents

2023 (or any stockholder-approved extension period), is not considered a liquidating distribution under Delaware law and such redemption distribution is deemed to be unlawful (potentially due to the imposition of legal proceedings that a party may bring or due to other circumstances that are currently unknown), then pursuant to Section 174 of the DGCL, the statute of limitations for claims of creditors could then be six years after the unlawful redemption distribution, instead of three years, as in the case of a liquidating distribution. If we are unable to complete our initial business combination by May 28, 2023 (or any stockholder-approved extension period), we will: (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a

per-share price,

payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to us to pay our taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public Stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and the Board, dissolve and liquidate, subject in the case of clauses (ii) and (iii) above to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. Accordingly, it is our intention to redeem our Public Shares as soon as reasonably possible following our 24

month and, therefore, we do not intend to comply with those procedures. As such, our stockholders could potentially be liable for any claims to the extent of distributions received by them (but no more) and any liability of our stockholders may extend well beyond the third anniversary of such date.

Because we will not be complying with Section 280 of the DGCL, Section 281(b) of the DGCL requires us to adopt a plan, based on facts known to us at such time that will provide for our payment of all existing and pending claims or claims that may be potentially brought against us within the subsequent ten years. However, because we are a blank check company, rather than an operating company, and our operations will be limited to searching for prospective target businesses to acquire, the only likely claims to arise would be from our vendors (such as lawyers, investment bankers, etc.) or prospective target businesses. As described above, pursuant to the obligation contained in our underwriting agreement, we will seek to have all vendors, service providers (other than our independent registered public accounting firm), prospective target businesses or other entities with which we do business execute agreements with us waiving any right, title, interest or claim of any kind in or to any monies held in the Trust Account. As a result of this obligation, the claims that could be made against us are significantly limited and the likelihood that any claim that would result in any liability extending to the Trust Account is remote. Further, the Sponsor may be liable only to the extent necessary to ensure that the amounts in the Trust Account are not reduced below (i) $10.00 per Public Share or (ii) such lesser amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, due to reductions in value of the trust assets, in each case net of the amount of interest withdrawn to pay taxes and will not be liable as to any claims under our indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act. In the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims.

If we file a bankruptcy petition or an involuntary bankruptcy petition is filed against us that is not dismissed, the proceeds held in the Trust Account could be subject to applicable bankruptcy law, and may be included in our bankruptcy estate and subject to the claims of third parties with priority over the claims of our stockholders. To the extent any bankruptcy claims deplete the Trust Account, we cannot provide any assurance that we will be able to return $10.00 per share to our Public Stockholders. Additionally, if we file a bankruptcy petition or an involuntary bankruptcy petition is filed against us that is not dismissed, any distributions received by stockholders could be viewed under applicable debtor/creditor and/or bankruptcy laws as either a “preferential transfer” or a “fraudulent conveyance.” As a result, a bankruptcy court could seek to recover some or all amounts received by our stockholders. Furthermore, our Board may be viewed as having breached its fiduciary duty to our creditors and/or may have acted in bad faith, thereby exposing itself and our company to claims of punitive damages, by paying Public Stockholders from the Trust Account prior to addressing the claims of creditors. We cannot provide any assurance that claims will not be brought against us for these reasons.

Competition

If we succeed in effecting the Business Combination with Senti, we may compete with a number of companies that have preclinical and early clinical-stage research programs underway to develop products that could potentially compete with Senti’s. Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are more effective, safer, have fewer or less severe side effects, are more convenient or are less expensive than the products that we may develop. We cannot assure you that, subsequent to the Business Combination, we will have the resources to compete effectively.

Facilities

Our executive offices are currently located at 2875 El Camino Real, Redwood City, CA 94061 and our telephone number is (408)

212-0200.

Our executive offices are provided to us by the Sponsor. We consider our current office space adequate for our current operations.

Employees

We currently have four executive officers. These individuals are not obligated to devote any specific number of hours to our matters but they intend to devote as much of their time as they deem necessary to our affairs until we have completed our initial business combination. The amount of time they will devote in any time period will vary based on whether a target business has been selected for our initial business combination and the stage of the initial business combination process we are in. We do not intend to have any other full- or part-time employees prior to the completion of our initial business combination.

Periodic Reporting and Financial Information

We have registered our Class A Common Stock under the Exchange Act and have reporting obligations, including the requirement that we file annual, quarterly and current reports with the SEC. In accordance with the requirements of the Exchange Act, we filed our amended quarterly report for the period ended September 30, 2021 with the SEC on December 10, 2021. This amended quarterly report contains financial statements audited and reported on by our independent registered public accountants.

We will be required to evaluate our internal control procedures for the fiscal year ending December 31, 2021 as required by the Sarbanes-Oxley Act. Only in the event we are deemed to be a large accelerated filer or an accelerated filer, and no longer qualify as an emerging growth company, will we be required to have an auditor attest to our internal control procedures. A target company may not be in compliance with the provisions of the Sarbanes-Oxley Act regarding adequacy of their internal controls. The development of the internal controls of any such entity to achieve compliance with the Sarbanes-Oxley Act may increase the time and costs necessary to complete any such business combination. We have filed a Registration Statement on

Form 8-A with

the SEC to voluntarily register our Class A Common Stock under Section 12 of the Exchange Act. As a result, we are subject to the rules and regulations promulgated under the Exchange Act. We have no current intention of filing a Form 15 to suspend our reporting or other obligations under the Exchange Act prior or subsequent to the consummation of our initial business combination.

We are an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the JOBS Act. As such, we are eligible to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies” including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a

non-binding advisory

vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. If some investors find our securities less attractive as a result, there may be a less active trading market for our securities and the prices of our securities may be more volatile.

193

Table of Contents

In addition, Section 107 of the JOBS Act also provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. In other words, an “emerging growth company” can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We intend to take advantage of the benefits of this extended transition period.

We will remain an emerging growth company until the earlier of (1) the last day of the fiscal year (a) following the fifth anniversary of the completion of the Initial Public Offering, (b) in which we have total annual gross revenue of at least $1.07 billion, or (c) in which we are deemed to be a large accelerated filer, which means the market value of our shares of Class A Common Stock that are held by

non-affiliates exceeds

$700 million as of the prior June 30

, and (2) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period. References herein to “emerging growth company” will have the meaning associated with it in the JOBS Act.

Additionally, we are a “smaller reporting company” as defined in Item 10(f)(1) of Regulation

S-K.

Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things, providing only two years of audited financial statements. We will remain a smaller reporting company if (1) the market value of our common stock held by

non-affiliates is

less than $250 million as of the last business day of the second fiscal quarter, or (2) our annual revenues in our most recent fiscal year completed before the last business day of our second fiscal quarter are less than $100 million and the market value of our common stock held by

non-affiliates is

less than $700 million as of the last business day of the second fiscal quarter.

Legal Proceedings

There is no material litigation, arbitration or governmental proceeding currently pending against us or any members of our management team in their capacity as such, and we and the members of our management team have not been subject to any such proceeding in the twelve months preceding the date of this proxy statement/prospectus.

Overview

We are a blank check company incorporated on March 1, 2021 as a Delaware corporation and formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. We intend to effectuate our initial business combination (the Business Combination) using cash from the proceeds of our Initial Public Offering and Concurrent Private Placement, the proceeds of the sale of our shares in connection with our initial business combination, shares issued to the current owners of Senti, debt issued to bank or other lenders or the owners of Senti, or a combination of the foregoing.

On May 28, 2021, we consummated our Initial Public Offering of 23,000,000 shares of Class A Common Stock, including 3,000,000 shares that were issued pursuant to the underwriters’ exercise of their over-allotment option in full. The shares of Class A Common Stock were sold at a price of $10.00 per share, generating gross proceeds of $230,000,000. J.P. Morgan Securities LLC acted as the sole book running manager of the Initial Public Offering. The securities sold in the Initial Public Offering were registered under the Securities Act on a registration statement on

Form S-1

(File

No. 333-255930).

The SEC declared the registration statement effective on May 25, 2021.

On May 28, 2021, simultaneously with the consummation of the Initial Public Offering, we completed the Concurrent Private Placement of an aggregate of 715,500 shares of Class A Common Stock (the “Private Placement Shares”) to Dynamics Sponsor LLC (our “Sponsor”) at a purchase price of $10.00 per Private Placement Share, generating gross proceeds to us of $7,155,000. Such securities were issued pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act.

A total of $230,000,000, comprised of $225,400,000 of the net proceeds from the Initial Public Offering (which amount included $8,050,000 of the underwriter’s deferred discount [(prior to such amount being reduced by $1,000,000 to $7,050,000 by written with J.P. Morgan Securities LLC on December 17, 2021)]) and $4,600,000, representing part of the proceeds of the sale of the Private Placement Shares, was placed in a

U.S.-based

Trust Account maintained by Continental Stock Transfer & Trust Company, acting as trustee.

Table of Contents

The issuance of additional shares in connection with the Business Combination to the current owners of Senti or other investors (including the PIPE Investors):

•

may significantly dilute the equity interest of DYSN stockholders, which dilution would increase if the anti-dilution provisions in the Class B Common Stock resulted in the issuance of shares of Class A Common Stock on a greater than

one-to-one

basis upon conversion of the Class B Common Stock;

•

may subordinate the rights of holders of our common stock if preferred stock is issued with rights senior to those afforded our common stock;

•

could cause a change in control if a substantial number of shares of our common stock is issued, which may affect, among other things, our ability to use our net operating loss carry forwards, if any, and could result in the resignation or removal of our present officers and directors;

•

may have the effect of delaying or preventing a change of control of us by diluting the stock ownership or voting rights of a person seeking to obtain control of us; and

•

may adversely affect prevailing market prices for our Class A Common Stock

Similarly, if we issue debt securities or otherwise incur significant debt to bank or other lenders or the owners of Senti, it could result in:

•

default and foreclosure on our assets if our operating revenues after the Business Combination are insufficient to repay our debt obligations;

•

acceleration of our obligations to repay the indebtedness even if we make all principal and interest payments when due if we breach certain covenants that require the maintenance of certain financial ratios or reserves without a waiver or renegotiation of that covenant;

•

our immediate payment of all principal and accrued interest, if any, if the debt is payable on demand;

•

our inability to obtain necessary additional financing if the debt contains covenants restricting our ability to obtain such financing while the debt is outstanding;

•

our inability to pay dividends on our common stock;

•

using a substantial portion of our cash flow to pay principal and interest on our debt, which will reduce the funds available for dividends on our common stock if declared, our ability to pay expenses, make capital expenditures and acquisitions, and fund other general corporate purposes;

•

limitations on our flexibility in planning for and reacting to changes in our business and in the industry in which we operate;

•

increased vulnerability to adverse changes in general economic, industry and competitive conditions and adverse changes in government regulation;

•

limitations on our ability to borrow additional amounts for expenses, capital expenditures, acquisitions, debt service requirements, and execution of our strategy; and

•

other purposes and other disadvantages compared to our competitors who have less debt.]

As indicated in the accompanying financial statements, as of [September 30], 2021, we had $[984,544] in cash (excluding funds held in the Trust Account). Further, we expect to incur significant costs in the pursuit of the Business Combination. We cannot assure you that our plans to raise capital or to complete the Business Combination will be successful.

Results of Operations and Known Trends or Future Events

We have neither engaged in any operations nor generated any revenues to date. Our only activities for the period from March 1, 2021 (inception) through December 31, 2021 were organizational activities, those necessary to prepare for our Initial Public Offering, described below, and, after the Initial Public Offering,

196

Table of Contents

identifying target companies for a business combination, conducting due diligence on such target companies and negotiating the Business Combination Agreement with Senti, which will give effect to our initial business combination. We do not expect to generate any operating revenues until after completion of our initial business combination. We generate

non-operating

income in the form of interest income on cash and cash equivalents held in the Trust Account following our Initial Public Offering. We incur expenses as a result of being a public company (for legal, financial reporting, accounting and auditing compliance), and we incurred expenses for due diligence in connection with identifying Senti as a target company for our initial business combination.

For the period from March 1, 2021 (inception) through September 30, 2021, we had a net loss of $498,924, which resulted from operating and formation costs of $407,500 and franchise tax expense of $95,349 partially offset by interest and dividend income on investments in Trust Account of $3,925.

For the three months ended September 30, 2021, we had a net loss of $291,680, which resulted from operating and formation costs of $253,456 and franchise tax expense of $41,184 partially offset by interest and dividend income on investments in Trust Account of $2,960.

Liquidity and Capital Resources

On May 28, 2021, we consummated the Initial Public Offering of 23,000,000 shares of Class A common stock (the “Public Shares”), including 3,000,000 Public Shares that were issued pursuant to the underwriters’ exercise of their over-allotment option in full, at $10.00 per Public Share, generating gross proceeds of $230,000,000.

Simultaneously with the closing of the Initial Public Offering, the Sponsor purchased an aggregate of 715,500 shares of Class A common stock at a price of $10.00 per share (the “Private Placement Shares”), generating gross proceeds of $7,155,000. A portion of the proceeds from the sale of the Private Placement Shares has been added to the net proceeds from the Initial Public Offering held in the trust account. If we do not complete our initial business combination within 24 months of the closing of the Initial Public Offering, the proceeds from the sale of the Private Placement Shares held in the trust account will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law).

For the period from March 1, 2021 (inception) through September 30, 2021, net cash used in operating activities was $1,047,026, which was primarily due to changes in working capital of $544,177, our net loss of $498,924, and non-cash interest and dividend income on investments held in the trust account of $3,925.

For the period from March 1, 2021 (inception) through September 30, 2021, net cash used in investing activities of $230,000,000 was the result of the amount of net proceeds from the Initial Public Offering and the private placement sale of shares being deposited to the Trust Account.

Net cash provided by financing activities for the period from March 1, 2021 (inception) through September 30, 2021 of $232,031,570 was comprised of $225,400,000 in proceeds from the issuance of shares in the Initial Public Offering net of underwriter’s discount paid, $7,155,000 in proceeds from the issuance of shares in a private placement to our Sponsor, and proceeds from the issuance of a promissory note to our sponsor of $250,000, offset by the payment of $523,430 for offering costs associated with the Initial Public Offering and repayment of the outstanding balance on the promissory note to our Sponsor of $250,000.

As of September 30, 2021, we had cash of $984,544 held outside the Trust Account. We intend to use the funds held outside the trust account primarily to identify and evaluate target businesses, perform business due diligence on prospective target businesses, travel to and from the offices, plants or similar locations of prospective target businesses or their representatives or owners, review corporate documents and material agreements of prospective target businesses, and structure, negotiate and complete a business combination.

197

Table of Contents

We intend to use substantially all of the funds held in the Trust Account, including any amounts representing interest earned on the trust account (less taxes payable and deferred underwriting commissions), to complete our initial business combination. We may withdraw interest income (if any) to pay income taxes, if any. Our annual income tax obligations will depend on the amount of interest and other income earned on the amounts held in the trust account. We expect the interest income earned on the amount in the Trust Account (if any) will be sufficient to pay our income taxes. To the extent that our equity or debt is used, in whole or in part, as consideration to complete our initial business combination, the remaining proceeds held in the Trust Account will be used as working capital to finance the operations of the target business or businesses, make other acquisitions and pursue our growth strategies.

We do not believe we will need to raise additional funds following this offering in order to meet the expenditures required for operating our business. However, if our estimates of the costs of identifying a target business, undertaking in-depth due diligence and negotiating an initial business combination are less than the actual amount necessary to do so, we may have insufficient funds available to operate our business prior to our initial business combination. In order to fund working capital deficiencies or finance transaction costs in connection with an intended initial business combination, our Sponsor or an affiliate of our Sponsor, or certain of our officers or directors may, but are not obligated to, loan us funds as may be required. If we complete our initial business combination, we would repay such loaned amounts. In the event that our initial business combination does not close, we may use a portion of the working capital held outside the Trust Account to repay such loaned amounts, but no proceeds from our Trust Account would be used for such repayment. Up to $2,000,000 of such loans may be convertible into shares of the post-business combination entity at a price of $10.00 per share at the option of the lender. The shares would be identical to the Private Placement Shares. The terms of such loans, if any, have not been determined and no written agreements exist with respect to such loans. We do not expect to seek loans from parties other than our Sponsor or an affiliate of our Sponsor, or certain of our officers or directors as we do not believe third parties will be willing to loan such funds and provide a waiver against any and all rights to seek access to funds in our Trust Account.

Related Party Transactions

Founder Shares

On March 8, 2021, we issued 5,750,000 shares of Class B Common Stock (the “Founder Shares”) to our Sponsor for an aggregate price of $25,000. These Founder Shares included an aggregate of up to 750,000 shares of Class B Common Stock subject to forfeiture by our Sponsor to the extent that the underwriter’s over-allotment option was not exercised in full or in part, so that our sponsor would own, on an as-converted basis, 20% of our issued and outstanding shares after our Initial Public Offering (excluding the Private Placement Shares and assuming our Sponsor did not purchase any public shares in our Initial Public Offering). The underwriter fully exercised the over-allotment option on May 28, 2021; thus, these 750,000 Founder Shares are no longer subject to forfeiture.

Private Placement

Simultaneously with the closing of our Initial Public Offering, we consummated the sale of 715,500 shares of Class A Common Stock (the “Private Placement Shares”) at a price of $10.00 per share in a private placement to our Sponsor, generating gross proceeds of $7,155,000. A portion of the proceeds from the sale of the Private Placement Shares was added to the net proceeds from our Initial Public Offering held in the Trust Account. If we do not complete an initial business combination within 24 months from the closing of our Initial Public Offering, the proceeds from the sale of the Private Placement Shares held in the Trust Account will be used to fund the redemption of public shares (subject to the requirements of applicable law).

Promissory Note — Related Party

On March 8, 2021, we issued an unsecured promissory note to our sponsor (the “Promissory Note”), pursuant to which we could borrow up to an aggregate of $300,000 to cover expenses related to our initial public offering. The Promissory Note was non-interest bearing and was payable on the earlier of December 31, 2021 or the consummation of our initial public offering. In April 2021, the Company borrowed $250,000 under the Promissory Note, which was repaid on May 26, 2021.

Administrative Support Agreement

We entered into an agreement, commencing on the effective date of our Initial Public Offering, to pay our Sponsor up to a total of $10,000 per month for office space, administrative and support services. Upon the completion of an initial business combination, the agreement will terminate. To date, we have not exercised our option to use such services and have not paid any fees to our Sponsor.

Related Party Loans

In addition, in order to finance transactions costs in connection with a business combination, the Sponsor, or certain of the Company’s officers, directors, or their affiliates may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes a business combination, the Company will repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a business combination is not completed, the Company may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. The Working Capital Loans would either be repaid upon consummation of a business combination, without interest, or, at the lender’s discretion, up to $2,000,000 of such Working Capital Loans may be converted into shares at a price of $10.00 per share at the option of the lender. The share would be identical to the Private Placement Shares.

Sponsor Support Agreement

In connection with the execution of the Business Combination Agreement, the Sponsor and each of our officers and directors entered into a support agreement with DYNS and Senti (the “Sponsor Support Agreement”). Under the Sponsor Support Agreement, the Sponsor has agreed to vote, at any meeting of the stockholders of DYNS and in any action by written consent of the stockholders of DYNS, all of its shares of Class B Common Stock (together with any other equity securities of DYNS that it holds of record or beneficially, as of the date of the Sponsor Support Agreement, or of which it acquires record or beneficial ownership after the date thereof (the “Subject DYNS Equity Securities”) (i) in favor of (a) the Business Combination Agreement and the transactions contemplated thereby and (b) the other proposals that DYNS and Senti agreed in the Business Combination Agreement shall be submitted at such meeting for approval by DYNS’s stockholders together with the proposal to obtain the DYNS stockholders’ approval for the Business Combination (the “Required Transaction Proposals”) and (ii) against any proposal that conflicts or materially impedes or interferes with any Required Transaction Proposals or that would adversely affect or delay the Business Combination. The Sponsor Support Agreement also prohibits the Sponsor from, among other things and subject to certain exceptions, selling, assigning or transferring any Subject DYNS Equity Securities held by the Sponsor or taking any action that would have the effect of preventing or materially delaying the Sponsor from performing its obligations under the Sponsor Support Agreement. In addition, in the Sponsor Support Agreement, the Sponsor agrees to waive, and not to assert or perfect, among other things, any rights to adjustment or other anti-dilution protections with respect to the rate at which the shares of Class B Common Stock held by the Sponsor convert into shares of Class A Common Stock in connection with the transactions contemplated by the Business Combination Agreement.

Commitments and Contingencies

Registration Rights

The holders of the Founder Shares and Private Placement Shares will be entitled to registration rights pursuant to the registration and stockholder rights agreement requiring us to register such securities for resale (in the case of the Founder Shares, only after conversion to our Class A Common Stock). The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company registers such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the completion of an initial business combination and rights to require us to register for resale such securities pursuant to Rule 415 under the Securities Act. The registration rights agreement does not contain liquidated damages or other cash settlement provisions resulting from delays in registering our securities. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriting Agreement

In connection with our initial public offering, the Company granted the underwriter a 45-day option to purchase up to 3,000,000 additional shares of Class A common stock to cover over-allotments at the initial public offering price, less the underwriting discounts and fees. The underwriter exercised its over-allotment option in full on May 28, 2021.

The underwriter was paid a cash underwriting fee of $0.20 per share, or $4,600,000 in the aggregate, upon the closing of our initial public offering. In addition, approximately $0.306 per share, or $7,050,000 in the aggregate, may be payable to the underwriter for deferred underwriting fees (this amount having being reduced from $8,050,000 by $1,000,000 by agreement with the underwriter on December 17, 2021). The deferred underwriting fee will become payable to the underwriter from the amounts held in the Trust Account solely in the event that the Company completes its initial business combination, subject to the terms of the underwriting agreement.

Risks and Uncertainties

Management is continuing to evaluate the impact of the

COVID-19

pandemic on the industry and has concluded that while it is reasonably possible that the virus could have a negative effect on our financial position and results of our operations, the specific impact is not readily determinable as of the date of these financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Off-Balance

Sheet Arrangements

As of September 30, 2021, we did not have any

off-balance

sheet arrangements as defined in Item 303(a)(4)(ii) of Regulation

S-K.

We do not participate in transactions that create relationships with unconsolidated entities or financial partnerships, often referred to as variable interest entities, which would have been established for the purpose of facilitating

off-balance

sheet arrangements. We have not entered into any

off-balance

sheet financing arrangements, established any special purpose entities, guaranteed any debt or commitments of other entities, or purchased any

non-financial

assets.

Critical Accounting Policies

The preparation of condensed financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and income and expenses during the periods reported. Actual results could materially differ from those estimates. We have identified the following critical accounting policies:

Net Loss Per Common Share

Net loss per common share is computed by dividing net loss by the weighted-average number of shares of common stock outstanding during the period. As the Public Shares are considered to be redeemable at fair value, and a redemption at fair value does not amount to a distribution different than other stockholders, Class A and Class B Common Stock are presented as one class of stock in calculating net loss per share. As a result, the calculated net loss per share is the same for Class A and Class B shares of common stock. At September 30, 2021, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into shares of common stock and then share in the earnings of the Company. As a result, diluted loss per share is the same as basic loss per share for the periods presented.

Class A Common Stock Subject to Possible Redemption

We account for our Class A common stock subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity. Shares of Class A Common Stock subject to mandatory redemption is classified as a liability instrument and measured at fair value. Conditionally redeemable common stock (including common stock that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within our control) is classified as temporary equity. At all other times, common stock is classified as stockholders’ equity. Our Class A Common Stock features certain redemption rights that are considered to be outside of our control and subject to occurrence of uncertain future events. Accordingly, Class A Common Stock subject to possible redemption is presented at redemption value as temporary equity, outside of the stockholders’ equity section of our condensed balance sheets. Immediately upon the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption amount value. The change in the carrying value of the redeemable Class A Common Stock subject to possible redemption resulted in charges against additional paid-in capital and accumulated deficit.

Recent Accounting Standards

In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-06, Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40) (“ASU 2020-06”) to simplify accounting for certain financial instruments. ASU 2020-06 eliminates the current models that require separation of beneficial conversion and cash conversion features from convertible instruments and simplifies the derivative scope exception guidance pertaining to equity classification of contracts in an entity’s own equity. The new standard also introduces additional disclosures for convertible debt and freestanding instruments that are indexed to and

201

Table of Contents

settled in an entity’s own equity. ASU 2020-06 amends the diluted earnings per share guidance, including the requirement to use the if-converted method for all convertible instruments. ASU 2020-06 is effective January 1, 2022 and should be applied on a full or modified retrospective basis, with early adoption permitted beginning on January 1, 2021. The Company is currently assessing the impact, if any, that ASU 2020-06 would have on its financial position, results of operations or cash flows.

Management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on our condensed financial statements.

JOBS Act

The JOBS Act contains provisions that, among other things, relax certain reporting requirements for qualifying public companies. We qualify as an “emerging growth company” and under the JOBS Act will be allowed to comply with new or revised accounting pronouncements based on the effective date for private (not publicly traded) companies. We are electing to delay the adoption of new or revised accounting standards, and as a result, we may not comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for

non-emerging

growth companies. As a result, our financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

Additionally, we are in the process of evaluating the benefits of relying on the other reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, if, as an “emerging growth company,” we choose to rely on such exemptions we may not be required to, among other things, (i) provide an auditor’s attestation report on our system of internal control over financial reporting pursuant to Section 404, (ii) provide all of the compensation disclosure that may be required of

non-emerging

growth public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act, (iii) comply with any requirement that may be adopted by the PCAOB regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (auditor discussion and analysis) and (iv) disclose certain executive compensation related items such as the correlation between executive compensation and performance and comparisons of the CEO’s compensation to median employee compensation. These exemptions will apply for a period of five years following the completion of our Initial Public Offering or until we are no longer an “emerging growth company,” whichever is earlier.

Quantitative and Qualitative Disclosures about Market Risk

We are a smaller reporting company as defined by

Rule 12b-2

of the Exchange Act and are not required to provide the information otherwise required under this item.

Mr. Flatley serves as Acting CEO and Chairman of Zymergen (Nasdaq: ZY), Chairman of Iridia, Inc. (privately held) and a director of Rivian Automotive, Inc. (Nasdaq: RIVN), Coherent, Inc. (Nasdaq: COHR) and Denali Therapeutics, Inc. (Nasdaq: DNLI). He is also on the Board of Trustees at the Salk Institute, and is Chair of Wellcome Leap, a

US-based

non-profit

organization founded by the Wellcome Trust to accelerate innovations that benefit global health. Mr. Flatley holds a BA in economics from Claremont McKenna College and a BS and MS in industrial engineering from Stanford University.

Deep Nishar—Independent Director:

As noted in our Form S-1 at the time of DYNS’s Initial Public Offering, we believe our Board and management team are well positioned to take advantage of the growing set of investment opportunities focused on the biotechnology sector, and that our contacts, relationships and investment and operating experience will allow us to generate an attractive transaction for our stockholders.

There are no family relationships between any Company director or executive officer.

Number and Terms of Office of Officers and Directors

We have five directors, with each director holding office for a

two-year

term. Prior to the completion of our initial business combination, any vacancy on the board of directors may be filled by a nominee chosen by holders of a majority of our shares of Class B Common Stock. In addition, prior to the completion of our initial business combination, holders of a majority of our shares of Class B Common Stock may remove a member of the board of directors for any reason.

Our officers are appointed by the board of directors and serve at the discretion of the board of directors. Our board of directors is authorized to appoint persons to the offices set forth in our bylaws as it deems appropriate. Our bylaws provide that our officers may consist of a Chief Executive Officer, President, Chief Financial Officer, Vice Presidents, Treasurer, Secretary, and such other offices as may be determined by the board of directors.

Director Independence

Nasdaq listing rules require that a majority of our board of directors be independent. An “independent director” is defined generally as a person other than an officer or employee of the company or its subsidiaries or

205

Table of Contents

any other individual having a relationship, which, in the opinion of the company’s board of directors, would interfere with the director’s exercise of independent judgment in carrying out the responsibilities of a director. We have three “independent directors” as defined in the Nasdaq listing rules and applicable SEC rules. Our board has determined that each of David Epstein, Jay Flatley and Deep Nishar, are independent directors under applicable SEC and Nasdaq listing rules. Our independent directors will have regularly scheduled meetings at which only independent directors are present. Each of our independent directors owns approximately 1.95% of the outstanding equity of our Sponsor.

Executive Officer and Director Compensation

In no event will our existing officers or directors receive any other cash- or equity-based compensation or be paid any finder’s fee, reimbursement, consulting fee or monies in respect of any payment of a loan by the company prior to, or in connection with any services rendered for any services they render in order to effectuate, the completion of our initial business combination (regardless of the type of transaction that it is), other than reimbursements for any

out-of-pocket

expenses incurred in connection with activities on our behalf such as identifying potential target businesses and performing due diligence on suitable business combinations. We do not have a policy that prohibits our sponsor, officers or directors, or any of their respective affiliates, from negotiating for the reimbursement of

out-of-pocket

expenses by a target business. Any such payments prior to an initial business combination will be made using funds held outside the trust account. Other than quarterly audit committee review of such payments, we do not expect to have any additional controls in place governing our reimbursement payments to our directors and officers for their

out-of-

pocket expenses incurred in connection with identifying and consummating an initial business combination.

After the completion of our initial business combination, directors or members of our management team who remain with us may be paid consulting or management fees or receive equity or equity-based awards from the Combined Company. These fees and awards will be disclosed to stockholders in accordance with applicable rules and regulations, to the extent then known, in the tender offer materials or proxy solicitation materials furnished to our stockholders in connection with a proposed initial business combination. We have not established any limit on the amount of such fees that may be paid by the Combined Company to our directors or members of management. It is unlikely the amount of such compensation will be known at the time of the proposed initial business combination, because the directors of the post-combination business will be responsible for determining officer and director compensation. Any compensation to be paid to our officers will be determined, or recommended to the board of directors for determination, either by a compensation committee constituted solely by independent directors or by a majority of the independent directors on our board of directors.

We do not intend to take any action to ensure that members of our management team maintain their positions with us after the consummation of our initial business combination, although it is possible that some or all of our officers and directors may negotiate employment or consulting arrangements to remain with us after our initial business combination. The existence or terms of any such employment or consulting arrangements to retain their positions with us may influence our management team’s motivation in identifying or selecting a target business but we do not believe that the ability of our management to remain with us after the consummation of our initial business combination will be a determining factor in our decision to proceed with any potential business combination. We are not party to any agreements with our officers and directors that provide for payments or benefits upon termination of employment.

Committees of the Board of Directors

Our Board has two standing committees: an audit committee and a compensation committee. Both our audit committee and our compensation committee are comprised solely of independent directors.

Audit Committee

We have established an audit committee of the board of directors. The members of our audit committee are David Epstein, Jay Flatley and Deep Nishar. Mr. Epstein serves as chairman of the audit committee.

206

Table of Contents

Messrs. Epstein, Flatley, and Nishar are independent of and unaffiliated with our sponsor and our underwriter. Under Nasdaq listing standards and applicable SEC rules, all the directors on the audit committee must be independent.

Each member of the audit committee is financially literate and our board of directors has determined that David Epstein qualifies as an “audit committee financial expert” as defined in applicable SEC rules and has accounting or related financial management expertise.

We have adopted an audit committee charter, which details the principal functions of the audit committee, including:

•

assisting board oversight of (1) the integrity of our financial statements, (2) our compliance with legal and regulatory requirements, (3) the independent registered public accounting firm’s qualifications and independence and (4) the performance of our internal audit function and the independent registered public accounting firm;

•

the appointment, compensation, retention, replacement, and oversight of the work of the independent registered account firm engaged by us;

•

pre-approving

all audit and permitted

non-audit

services to be provided by the independent registered public accounting firm engaged by us, and establishing

pre-approval

policies and procedures;

•

setting clear hiring policies for employees or former employees of the independent registered public accounting firm, including but not limited to, as required by applicable laws and regulations;

•

setting clear policies for audit partner rotation in compliance with applicable laws and regulations;

•

obtaining and reviewing a report, at least annually, from the independent registered public accounting firm describing (i) the independent registered public accounting firm’s internal quality-control procedures, (ii) any material issues raised by the most recent internal quality-control review, or peer review, of the audit firm, or by any inquiry or investigation by governmental or professional authorities within the preceding five years respecting one or more independent audits carried out by the firm and any steps taken to deal with such issues and (iii) all relationships between the independent registered public accounting firm and us to assess the independent registered public accounting firm’s independence;

•

meeting to review and discuss our annual audited financial statements and quarterly financial statements with management and the independent registered public accounting firm, including reviewing our specific disclosures under “DYNS Management’s Discussion and Analysis of Financial Condition and Results of Operations;”

•

reviewing and approving any related party transaction required to be disclosed pursuant to Item 404 of Regulation

S-K promulgated

by the SEC prior to us entering into such transaction; and

•

reviewing with management, the independent registered public accounting firm, and our legal advisors, as appropriate, any legal, regulatory or compliance matters, including any correspondence with regulators or government agencies and any employee complaints or published reports that raise material issues regarding our financial statements or accounting policies and any significant changes in accounting standards or rules promulgated by the Financial Accounting Standards Board, the SEC or other regulatory authorities.

Nominating Committee

We do not have a standing nominating committee though we intend to form a corporate governance and nominating committee as and when required to do so by law or Nasdaq rules. In accordance with Rule 5605 of the Nasdaq rules, a majority of the independent directors may recommend a director nominee for selection by the

207

Table of Contents

board of directors. The board of directors believes that the independent directors can satisfactorily carry out the responsibility of properly selecting or approving director nominees without the formation of a standing nominating committee. The directors who will participate in the consideration and recommendation of director nominees are [ ]. In accordance with Rule 5605 of the Nasdaq rules, all such directors are independent. As there is no standing nominating committee, we do not have a nominating committee charter in place.

The Board will also consider director candidates recommended for nomination by our stockholders during such times as they are seeking proposed nominees to stand for election at the next annual meeting of stockholders (or, if applicable, a Special Meeting of stockholders). Our stockholders that wish to nominate a director for election to our board of directors should follow the procedures set forth in our Bylaws.

We have not formally established any specific, minimum qualifications that must be met or skills that are necessary for directors to possess. In general, in identifying and evaluating nominees for director, the board of directors considers educational background, diversity of professional experience, knowledge of our business, integrity, professional reputation, independence, wisdom, and the ability to represent the best interests of our stockholders.

Compensation Committee

We have established a compensation committee of the Board. The members of our compensation committee are David Epstein, Jay Flatley and Deep Nishar. Mr. Flatley serves as chairman of the compensation committee. Messrs. Epstein, Flatley and Nishar are independent of and unaffiliated with our sponsor and our underwriter. Under Nasdaq listing standards, all the directors on the compensation committee must be independent.

We have adopted a compensation committee charter, which details the principal functions of the compensation committee, including:

•

reviewing and approving on an annual basis the corporate goals and objectives relevant to our Chief Executive Officer’s compensation, if any is paid by us, evaluating our Chief Executive Officer’s performance in light of such goals and objectives and determining and approving the remuneration (if any) of our Chief Executive Officer based on such evaluation;

•

reviewing and making recommendations on an annual basis to our board of directors with respect to (or approving, if such authority is so delegated by our board of directors) the compensation, if any is paid by us, and any incentive-compensation and equity-based plans that are subject to board approval of our other officers;

•

reviewing on an annual basis our executive compensation policies and plans;

•

implementing and administering our incentive compensation equity-based remuneration plans;

•

assisting management in complying with our proxy statement and annual report disclosure requirements;

•

approving all special perquisites, special cash payments and other special compensation and benefit arrangements for our officers and employees;

•

if required, producing a report on executive compensation to be included in our annual proxy statement; and

•

reviewing, evaluating and recommending changes, if appropriate, to the remuneration for directors.

Until the earlier of the consummation of our initial business combination or our liquidation and in connection with potentially providing financing or other investments in connection with our initial business combination, no compensation of any kind, including finders, consulting or other similar fees, will be paid to any of our existing stockholders, officers, directors or any of their respective affiliates, prior to, or for any services

208

Table of Contents

they render in order to effectuate the consummation of an initial business combination. Accordingly, it is likely that prior to the consummation of an initial business combination, the compensation committee will only be responsible for the review and recommendation of any compensation arrangements to be entered into in connection with such initial business combination.

The charter also provides that the compensation committee may, in its sole discretion, retain or obtain the advice of a compensation consultant, legal counsel or other adviser and will be directly responsible for the appointment, compensation and oversight of the work of any such adviser. However, before engaging or receiving advice from a compensation consultant, external legal counsel or any other adviser, the compensation committee will consider the independence of each such adviser, including the factors required by Nasdaq and the SEC.

Compensation Committee Interlocks and Insider Participation

None of our executive officers currently serves, and in the past year has not served, as a member of the compensation committee of any entity that has one or more executive officers serving on our Board.

Code of Ethics

We have adopted a Code of Ethics applicable to our directors, officers and employees, a copy of which is available on our website. In addition, a copy of the Code of Ethics will be provided without charge upon request from us. We intend to disclose any amendments to or waivers of certain provisions of our Code of Ethics in a Current Report on Form

8-K.

Conflicts of Interest

Subject to

pre-existing

fiduciary or contractual duties as described below, our officers and directors have agreed to present any business opportunities presented to them in their capacity as a director or officer of DYNS to us. Certain of our officers and directors presently have fiduciary or contractual obligations to other entities pursuant to which such officer or director is or may be required to present a business combination opportunity. Accordingly, if any of our officers or directors becomes aware of a business combination opportunity which is suitable for an entity to which he or she has then-current fiduciary or contractual obligations, he or she will honor his or her fiduciary or contractual obligations to present such opportunity to such entity. We believe, however, that the fiduciary duties or contractual obligations of our officers or directors will not materially affect our ability to complete our initial business combination. Our Current Charter provides that we renounce our interest in any corporate opportunity offered to any director or officer unless such opportunity is expressly offered to such person solely in his or her capacity as a director or officer of DYNS and such opportunity is one we are legally and contractually permitted to undertake and would otherwise be reasonable for us to pursue, and to the extent the director or officer is permitted to refer that opportunity to us without violating another legal obligation.

Potential investors should also be aware of the following other potential conflicts of interest:

•

None of our officers or directors is required to commit his or her full time to our affairs and, accordingly, may have conflicts of interest in allocating his or her time among various business activities.

•

In the course of their other business activities, our officers and directors may become aware of investment and business opportunities which may be appropriate for presentation to us as well as the other entities with which they are affiliated. Our management may have conflicts of interest in determining to which entity a particular business opportunity should be presented.

•

Our Sponsor, and each of our officers and directors have agreed to (i) waive their redemption rights with respect to their founder shares and any public shares held by them in connection with the completion of our initial business combination, (ii) waive their redemption rights with respect to their

209

Table of Contents

Founder Shares and any Public Shares held by them in connection with a stockholder vote to approve an amendment to our amended and restated certificate of incorporation (A) to modify the substance or timing of our obligation to allow redemption in connection with our initial business combination or to redeem 100% of our public shares if we do not complete our initial business combination within 24 months from the closing of this offering or (B) with respect to any other provision relating to stockholders’ rights or

pre-

initial business combination activity and (iii) waive their rights to liquidating distributions from the trust account with respect to their founder shares if we fail to complete our initial business combination within 24 months from the closing of this offering or during any stockholder-approved extension period, although they will be entitled to liquidating distributions from the trust account with respect to any public shares they hold if we fail to complete our initial business combination within the prescribed timeframe. If we do not complete our initial business combination within such applicable time period, the proceeds of the sale of the Private Placement Shares held in the trust account will be used to fund the redemption of our Public Shares, and the Private Placement Shares will expire worthless. With certain limited exceptions, the founder shares will not be transferable or assignable until the earlier of: (A) one year after the completion of our initial business combination or (B) subsequent to our initial business combination, (x) if the last reported sale price of our Class A Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any

30-trading

day period commencing at least 150 days after our initial business combination, or (y) the date on which we complete a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of our stockholders having the right to exchange their shares of Class A Common Stock for cash, securities or other property. With certain limited exceptions, the Private Placement Shares will not be transferable, assignable or saleable by our sponsor or its permitted transferees until 30 days after the completion of our initial business combination. Since our Sponsor and officers and directors may directly or indirectly own common stock following this offering, our officers and directors may have a conflict of interest in determining whether a particular target business is an appropriate business with which to effectuate our initial business combination.

•

Our officers and directors may have a conflict of interest with respect to evaluating a particular business combination if the retention or resignation of any such officers and directors was included by a target business as a condition to any agreement with respect to our initial business combination.

•

Our Sponsor, officers or directors may have a conflict of interest with respect to evaluating a business combination and financing arrangements as we may obtain loans from the Sponsor or an affiliate of the Sponsor or any of our officers or directors to finance transaction costs in connection with an intended initial business combination. As of [ ], 2022, no such loans are outstanding. The terms of such loans, if any are made, have not been determined and no written agreements exist with respect to such loans. The loans would either be repaid upon consummation of a business combination, without interest, or, at the lender’s discretion, up to $2,000,000 of such loans may be converted into shares of the post-business combination entity at a price of $10.00 per share at the option of the lender, and it is expected that the shares issued upon conversion of such loans would be identical to the Private Placement Shares.

The conflicts described above may not be resolved in our favor.

In general, officers and directors of a corporation incorporated under the laws of the State of Delaware are required to present business opportunities to a corporation if:

•

the corporation could financially undertake the opportunity;

•

the opportunity is within the corporation’s line of business; and

•

it would not be fair to our company and its stockholders for the opportunity not to be brought to the attention of the corporation.

210

Table of Contents

Accordingly, as a result of multiple business affiliations, our officers and directors may have similar legal obligations relating to presenting business opportunities meeting the above-listed criteria to multiple entities. Furthermore, our Current Charter provides that we renounce our interest in any corporate opportunity offered to any director or officer unless such opportunity is expressly offered to such person solely in his or her capacity as a director or officer of our company and such opportunity is one we are legally and contractually permitted to undertake and would otherwise be reasonable for us to pursue, and to the extent the director or officer is permitted to refer that opportunity to us without violating another legal obligation.

The individuals listed in the table above may also be affiliated with and/or owe fiduciary duties to or have contractual obligations to affiliates of the listed entities, including subsidiaries, portfolio companies and other investments and ventures of the listed entities.

We are not prohibited from pursuing an initial business combination or subsequent transaction with a company that is affiliated with the Sponsor, our officers or our directors. In the event we seek to complete our initial business combination or, subject to certain exceptions, subsequent material transactions with a company that is affiliated with the Sponsor, our officers or our directors, we, or a committee of independent directors, to the extent required by applicable law or based upon the direction of our board of directors or a committee thereof, will obtain an opinion from an independent investment banking firm or another entity that commonly renders valuation opinions that such initial business combination or transaction is fair to our company from a financial point of view. We are not required to obtain such an opinion in any other context. Furthermore, in no event will the Sponsor or any of our existing officers or directors, or any of their respective affiliates, be paid by the company any finder’s fee, consulting fee or other compensation prior to, or for any services they render in order to effectuate, the completion of our initial business combination.

We cannot assure you that any of the above mentioned conflicts will be resolved in our favor.

In the event that we submit our initial business combination to our Public Stockholders for a vote, pursuant to the letter agreement, the Sponsor and each of our officers and directors have agreed to vote any Founder Shares held by them and any Public Shares purchased during or after the offering (including in open market and privately negotiated transactions) in favor of our initial business combination.

Limitation on Liability and Indemnification of Officers and Directors

Our Current Charter provides that our officers and directors will be indemnified by us to the fullest extent authorized by Delaware law, as it now exists or may in the future be amended. In addition, our Current Charter provides that our directors will not be personally liable for monetary damages to us or our stockholders for breaches of their fiduciary duty as directors, unless they violated their duty of loyalty to us or our stockholders, acted in bad faith, knowingly or intentionally violated the law, authorized unlawful payments of dividends, unlawful stock purchases or unlawful redemptions, or derived an improper personal benefit from their actions as directors.

We have entered into agreements with our officers and directors to provide contractual indemnification in addition to the indemnification provided for in our Current Charter. Our Bylaws also permit us to secure insurance on behalf of any officer, director or employee for any liability arising out of his or her actions,

212

Table of Contents

regardless of whether Delaware law would permit such indemnification. We have purchased a policy of directors’ and officers’ liability insurance that insures our officers and directors against the cost of defense, settlement or payment of a judgment in some circumstances and insures us against our obligations to indemnify our officers and directors.

These provisions may discourage stockholders from bringing a lawsuit against our directors for breach of their fiduciary duty. These provisions also may have the effect of reducing the likelihood of derivative litigation against officers and directors, even though such an action, if successful, might otherwise benefit us and our stockholders. Furthermore, a stockholder’s investment may be adversely affected to the extent we pay the costs of settlement and damage awards against officers and directors pursuant to these indemnification provisions.

We believe that these provisions, the directors’ and officers’ liability insurance and the indemnity agreements are necessary to attract and retain talented and experienced officers and directors.

Executive and Director Compensation

None of our officers has received any cash compensation for services rendered to us. No compensation of any kind, including any finder’s fee, reimbursement, consulting fee or monies in respect of any payment of a loan, will be paid by us to the Sponsor, officers or directors or any affiliate of the Sponsor, officers or directors, prior to, or in connection with any services rendered in order to effectuate, the consummation of our initial business combination (regardless of the type of transaction that it is). However, these individuals will be reimbursed for any

out-of-pocket expenses

incurred in connection with activities on our behalf such as identifying potential target businesses and performing due diligence on suitable business combinations. Our audit committee will review on a quarterly basis all payments that were made to the Sponsor, officers or directors or our or their affiliates. Any such payments prior to an initial business combination will be made using funds held outside the Trust Account. Other than quarterly audit committee review of such payments, we do not expect to have any additional controls in place governing our reimbursement payments to our directors and executive officers for their

out-of-pocket expenses

incurred in connection with identifying and consummating an initial business combination.

We do not intend to take any action to ensure that members of our management team maintain their positions with us after the consummation of our initial business combination, although it is possible that some or all of our officers and directors may negotiate employment or consulting arrangements to remain with us after our initial business combination. The existence or terms of any such employment or consulting arrangements to retain their positions with us may influence our management’s motivation in identifying or selecting a target business but we do not believe that the ability of our management to remain with us after the consummation of our initial business combination will be a determining factor in our decision to proceed with any potential business combination. We are not party to any agreements with our officers and directors that provide for benefits upon termination of employment.

BUSINESS

Overview

We are a preclinical biotechnology company developing next-generation cell and gene therapies engineered with our gene circuit platform technologies to fight challenging diseases. Our mission is to create a new generation of smarter therapies that can outmaneuver complex diseases in ways previously not implemented by conventional medicines. To accomplish this mission, we have built a synthetic biology platform that we believe may enable us to program next-generation cell and gene therapies with what we refer to as “gene circuits.” These gene circuits, which we created from novel and proprietary combinations of genetic parts, are designed to reprogram cells with biological logic to sense inputs, compute decisions and respond to their respective cellular environments. We aim to design and optimize gene circuits through our Design-Build-Test-Learn Engine, or DBTL Engine, to improve the “intelligence” of cell and gene therapies in order to enhance their therapeutic effectiveness against a broad range of diseases that conventional medicines are unable to address. Our gene circuit platform technologies can be applied in a modality-agnostic manner, with applicability to natural killer (NK) cells, T cells, tumor infiltrating lymphocytes (TILs), stem cells including Hematopoietic Stem Cells (HSCs),

in vivo

gene therapy and messenger ribonucleic acid (mRNA). All of our current product candidates are in preclinical development. Our lead product candidates utilize allogeneic chimeric antigen receptor (CAR) NK cells outfitted with our gene circuit technologies in several oncology indications with currently high unmet need. Subject to the successful identification of lead product candidates and completion of IND- enabling studies, we expect to file investigational new drug applications, or INDs, for multiple product candidates starting in 2023.

The field of synthetic biology has evolved rapidly over the past few decades, and we believe that we are uniquely positioned to harness its potential to drive significant advances in medicine. Our scientific team is comprised of leaders in the space, and we have leveraged their expertise to create our scalable DBTL Engine and develop a proprietary knowledge database for therapeutic gene circuits. Our founders, Dr. Tim Lu, Dr. Philip Lee, Prof. James Collins, and Prof. Wilson Wong are pioneers in synthetic biology, gene circuits and cell and gene therapy, each having spent over twenty years advancing next-generation technologies in these areas. Our scientific founders and advisors are among the foremost leaders in their respective fields, having collectively published many of the seminal scientific papers in synthetic biology in top journals such as Nature, Science and Cell. Integrating disciplines from biology, chemistry and computer science, we have leveraged recent advances in DNA sequencing and synthesis, high-throughput experimentation and computational design, together with our intellectual property, to design, build and test gene circuits. We believe these are novel technologies, and we are not aware of U.S. Food and Drug Administration, or FDA, approved therapeutics utilizing similar technologies. As a result, these technologies may require significant resources in order to achieve regulatory approval. In preclinical studies, we have shown that our gene circuits are capable of carrying out sophisticated biological functions in a variety of disease models and we are preparing to advance our product candidates to clinical studies. We believe in the potential of gene circuits to enhance efficacy, precision and control of numerous cell and gene therapy products. Ultimately, we envision that cells running computations using our gene circuits in the human body will be able to outsmart a myriad of complex diseases.

The following figure illustrates how our gene circuit platform technologies may enable the creation of smarter medicines that can “sense inputs,” “compute decisions” and “respond with outputs” to impact diseases:

Key Challenges to Existing Disease Treatments and Our Gene Circuit Solutions

Key Challenges to Existing Disease Treatments

Diseases often involve complex biological interactions, which limit the effectiveness of existing therapeutics that only have single mechanisms of action and are unable to adapt to dynamic disease states. We characterize these key challenges in the following four categories:


		Target Heterogeneity: Many diseases are heterogeneous and express antigens that are also present on healthy cells. The overlap of antigen expression on diseased and healthy cells limits the ability of existing therapies to target diseased cells at therapeutically relevant doses due to undesirable effects against healthy cells. For example, most cancers do not have a single antigen target that is uniformly expressed on all cancer cells with limited to no expression on non-cancerous cells. Thus, the ability to precisely distinguish between diseased cells and healthy cells has been a central challenge to date with current therapeutic approaches that do not encode logic, such as monoclonal antibodies, antibody-drug conjugates and single-target CAR therapies. Modalities that can respond to multiple biomarkers, rather than just a single one, have the potential to open up the opportunity for more precise and efficacious medicines.
		Disease Evasion: Disease pathologies are multifaceted. For example, diseases can evade the immune system or acquire resistance to single-target treatments by activating other biological pathways. The tumor microenvironment of many solid tumors suppresses cancer-fighting immune cells via multiple pathways. To overcome these complex barriers, combination therapies that utilize multiple individual drugs are being explored clinically. However, manufacturing issues, regulatory aspects, pharmacology complexities and clinical challenges of using multiple individual drugs together can be difficult. A gene or cell therapy with the ability to activate multiple anti-tumor pathways within a single product could help limit disease evasion and may improve the durability of responses to treatment, while simplifying the translational path.
		Narrow Therapeutic Window: Once administered to a patient, conventional medicines, including cell and gene therapies, cannot be tuned up or down, which makes it difficult to find the optimal dose,

215

		especially for diseases that have a narrow therapeutic window. The ability to create therapeutics that can be titrated or regulated in vivo in the patient may lead to enhanced efficacy and safety.
		Dynamic Disease Conditions: Disease conditions are dynamic and vary in space and time. For example, diseases may manifest only in certain tissues, or have a waxing and waning progression over time. Conventional therapies are (i) static, (ii) have a predefined activity around a single mechanism of action that cannot be modified post-administration and (iii) do not adapt to these dynamic conditions, thus limiting their efficacy, specificity and safety. For example, current cell and gene therapies are not dynamic or highly specific, thus limiting the indications that they can address. Developing dynamic therapeutics that are able to sense, and respond to, these spatially or temporally varying conditions would address this challenge.

Our Gene Circuit Solutions

We believe that our core gene circuit platform technologies may enable us to engineer smarter medicines. These technologies can be categorized as follows.


		Logic Gating: Logic Gating gene circuits are designed to enable cell and gene therapies to control their therapeutic activity in response to the presence or absence of multiple disease biomarkers. Below are examples of Logic Gates applied to cancer, although Logic Gating may also be applied to various other disease indications.
				NOT GATE: NOT GATE gene circuits are designed to widen the therapeutic window by enabling effective killing of cancer cells while preserving healthy cells. The NOT GATE functions by recognizing Safety Antigens (SAs), or antigens that are selectively expressed on healthy cells and not on cancer cells, thus limiting on-target, off-tumor killing. By protecting healthy cells, the NOT GATE has the potential to enable more effective on-target, on-tumor killing of tumor cells that express Tumor-Associated Antigens (TAAs). Generally, existing cancer drugs target only a single antigen, which means they can only be effectively and safely used in situations where that antigen is uniquely expressed on tumors and not in healthy cells, or where the on-target, off-tumor effects are tolerable.
				OR GATE: OR GATE gene circuits are designed to address tumor heterogeneity and limit antigen escape. The OR GATE functions by killing tumor cells that express any one of multiple antigens. Generally, current medicines are unable to address more than one target at a time and are thus susceptible to tumor evasion.
				AND GATE: AND GATE gene circuits require that multiple targets be present at the same time to trigger killing of cancer cells, which may enhance the specificity of on-target, on-tumor activity. Generally, conventional therapies only recognize a single antigen for their activity, which can result in a lack of specificity.
		Multi-Arming: Multi-Arming gene circuits are designed to incorporate multiple payloads into a single cell or gene therapy product. These gene circuits are intended to activate various biological pathways in complementary ways to prevent diseases from evading single-target treatments, and thereby potentially improve treatment efficacy. Existing combination therapies that target complex diseases require the application of multiple individual drugs, which is difficult due to research, clinical development, regulatory and pharmacology barriers.
		Regulator Dial: Regulator Dial gene circuits are designed to enable the precise tuning of therapeutic activity from a cell or gene therapy product. For example, this can be implemented by regulating therapeutic payload expression in response to varying concentrations of FDA-approved drugs. Regulator Dials are expected to enable the exogenous regulation of next-generation cell and gene

216

		therapies even after they have been delivered in vivo . Existing cell and gene therapies cannot be modulated once they have been delivered into patients.
		Smart Sensor: A Smart Sensor is a gene circuit, or combination of gene circuits, designed to precisely detect distinct cell types or disease environments, and thus distinguish between the “disease state” and “healthy state.” For example, Smart Sensors can be engineered to detect whether certain conditions, or disease biomarkers, are present before responding with a specific therapeutic response. Conventional medicines are generally unable to dynamically change their behavior in response to cell or disease specific conditions.

We believe we can rationally combine any of these four gene circuit platform technologies to strategically customize therapeutics to outmaneuver complex diseases. The following figure maps how our gene circuit platform technologies are designed to address specific challenges facing existing medicines:

We Believe Our Gene Circuits May Have Broad Applicability in Multiple Treatment Modalities and Disease Areas

Treatment Modalities

Our gene circuit biological “software” can be used to program numerous cell and gene therapy products, or “hardware.” Specifically, these modalities include NK cells, T cells, TILs, stem cells including HSCs,

in vivo

gene therapy and mRNA.

We have conducted research in multiple cell types and vector types, and the initial focus of our internal pipeline is implementing gene circuits within allogeneic

CAR-NK

cells.

Disease Areas

Our gene circuits can be customized to address many aspects of disease biology. We have demonstrated and published on applications of gene circuits across many different

in vivo

disease models. Thus, we believe that our gene circuit platform technologies have the potential to be used for a broad range of diseases that span therapeutic areas such as oncology, immunology, genetic diseases, neurology, cardiology, metabolic diseases, ophthalmology and regenerative medicine.

217

The following figure presents our perspective on how our gene circuit technologies can be utilized across modalities and corresponding therapeutic areas:

We Utilize Our Design-Build-Test-Learn Engine to Optimize Our Gene Circuits

We have established, and continue to scale, our powerful DBTL Engine to generate our therapeutic gene circuits. We believe the speed, quantity and quality by which we can design multiple types of gene circuits, resulting in thousands of functional gene circuits engineered to date, is unique to our platform. Our gene circuits are engineered by an expert team of synthetic biologists informed by proprietary bioinformatics and our internal gene circuits knowledge database. This proprietary knowledge database contains quantitative characterization data on gene circuits we have previously built, including those that are functional and those that are not. Thus, this database helps inform the design of future gene circuits guided by our past experiences. Furthermore, we leverage machine learning approaches to continually enhance the design of such gene circuits based on data generated through testing in our

in vitro

and

in vivo

disease models. The breadth and scale of our DBTL Engine allows us to learn from each cycle of design to improve the speed and quality of future designs—even across projects and modalities. This approach leverages and reinforces our position as leaders and innovators in the field of synthetic biology for the development of human therapeutics. Based on decades of experience among our founders as well as the accumulated data from our DBTL Engine, we believe that our approach to programming gene circuits is broadly applicable toward engineering optimal efficacy, precision and control into many cell or gene-based medicines.

Our Pipeline and Product Candidates

We believe that our gene circuits enable us to address indications that conventional small molecule, protein and cell and gene therapies cannot. We intend to seek feedback from the FDA and comparable regulatory authorities given the novelty of our technologies, which could make the regulatory pathway more complex and potentially time-consuming than for more well-known therapeutics. Our most advanced gene-circuit product candidates are directed at allogeneic

CAR-NK

cells for oncology. In addition to these product candidates, we have discovery stage product candidates focused on gene therapies for tissue-directed targets and cell therapies for regenerative medicines. The following pipeline chart depicts our preclinical stage product candidates.

SENTI-202

We are developing our

SENTI-202

product candidate as a Logic Gated (OR + NOT) allogeneic

CAR-NK

cell therapy designed to target and eliminate acute myeloid leukemia, or AML, cells while sparing the healthy bone marrow. We are engineering

SENTI-202

to express a bivalent CAR as an OR GATE directed against the Tumor-Associated Antigens, Fms-like tyrosine kinase 3 (FLT3) or Cluster of Differentiation 33 (CD33), where one or both are expressed in 95% of AML patients. FLT3 is highly expressed on leukemic stem cells, or LSCs, while CD33 is highly expressed on AML blasts. AML is a heterogeneous disease composed of both AML LSCs and blasts. Thus, we believe that targeting FLT3 OR CD33 will enhance the overall killing activity against diseased cells in AML. However, FLT3 is also expressed on healthy hematopoietic stem cells, or HSCs, in the bone marrow. In order to spare FLT3-expressing healthy HSCs, we have further engineered

SENTI-202

with a NOT GATE gene circuit comprised of an inhibitory CAR, or iCAR, targeted against endomucin, or EMCN. EMCN is a Safety Antigen with high expression on HSCs and low expression on AML LSCs and blasts. We believe this NOT GATE gene circuit could allow

SENTI-202

to eliminate LSCs that cause relapse while

219

Table of Contents

preserving the patient’s HSCs. This proprietary product profile has the potential to drive towards a cure for AML without the need for a bone marrow transplant by enabling killing of diverse AML cells while sparing HSCs that regenerate the blood and the immune systems. We are also engineering

SENTI-202

to express our proprietary calibrated release interleukin 15, or

crIL-15,

to promote NK cell persistence and tumor killing. Our

crIL-15

construct is being designed to simultaneously produce both membrane associated and fully secreted

IL-15

proteins for more optimal cytokine signaling.

In 2022, we plan to present

IND-enabling

pharmacological data at key scientific conferences, seek feedback from the FDA through a

pre-IND

meeting, and apply for Orphan Drug Designation. In 2023, we plan to submit an IND application to support the clinical evaluation of

SENTI-202.

SENTI-301

Our

SENTI-301

product candidate is a Multi-Armed allogeneic

CAR-NK

cell therapy that we are developing for the treatment of hepatocellular carcinoma, or HCC. We are engineering NK cells to target glypican 3, or GPC3, which is highly expressed in 70% to 90% of HCCs and has low or no expression on normal adult tissues.

SENTI-301

is armed with a combination of immuno-stimulatory payloads intended to promote expansion and persistence of our

CAR-NK

cells, as well as activation and recruitment of endogenous immune cells into the solid tumor microenvironment for enhanced anti-tumor activity. One of the immuno-stimulatory payloads is our proprietary

crIL-15

protein.

crIL-15

is designed for enhanced cytokine signaling to promote NK cell persistence and tumor killing. We are further engineering

SENTI-301

with the capability to produce the potent immune effector interleukin 12, or

IL-12,

where expression is modulated via a small-molecule Regulator Dial gene circuit.

In 2022, we plan to present

IND-enabling

pharmacological data at key scientific conferences, seek feedback from the FDA through a

pre-IND

meeting, and apply for Orphan Drug Designation. In 2023, we plan to submit an IND application to support the clinical evaluation of

SENTI-301.

SENTI-401

Our

SENTI-401

product candidate is a Logic Gated allogeneic

CAR-NK

cell therapy that we are developing to more precisely target and eliminate colorectal cancer, or CRC, cells while sparing healthy cells elsewhere in the body. We are engineering NK cells to express a CAR directed against carcinoembryonic antigen, or CEA, which is highly overexpressed in 85% to 90% of colorectal cancer but is also expressed in epithelial cells in healthy tissues. The expression profile of CEA in both tumor and healthy cells has resulted in

on-target,

off-tumor

toxicities with conventional

CEA-targeted

therapies, thus limiting their clinical success. To address this challenge, we are engineering

SENTI-401

with a NOT GATE implemented via an iCAR targeted against an epithelial cell Safety Antigen called

V-set

and Immunoglobulin Domain Containing 2, or VSIG2. Thus, the

SENTI-401

product candidate’s Logic Gating is intended to more effectively treat CRC patients by targeting a well-known Tumor-Associated Antigen, CEA, and widen the therapeutic window by preventing killing when CEA appears on healthy cells that also expresses the VSIG2 Safety Antigen.

In 2023, we plan to present

IND-enabling

pharmacological data at key scientific conferences and seek feedback from the FDA through a

pre-IND

meeting.

Our Discovery Stage Programs

Our current discovery stage programs are as follows:

We believe our gene circuits can be readily adapted to new disease contexts to enable a variety of additional

CAR-NK

product candidates that address important cancers. Our

SENTI-411

and

SENTI-421

product candidates are Logic Gated

CAR-NKs

that leverage the same NOT GATE gene circuit technology deployed in

SENTI-202

and

SENTI-401.

We are developing these product candidates for precise targeting of solid or liquid tumors expressing certain Tumor-Associated Antigens, while protecting against

on-target,

off-tumor

toxicity toward healthy cells in order to widen the therapeutic window. Additionally, our

SENTI-311

product candidate is a

CAR-NK

that utilizes our Multi-Arming gene circuit technology currently deployed in our

SENTI-301

product candidate.

SENTI-311

is being developed for the treatment of solid tumors, where Multi-Arming is designed to overcome disease evasion.

Furthermore, we are actively pursuing the nomination and development of multiple product candidates that harness the full breadth of our gene circuit platform beyond Logic Gating and Multi-Arming of allogeneic

CAR-NK

cells within oncology. In particular, we have entered into collaborations with Spark Therapeutics, Inc. (acquired by Roche Holding AG) for the design of Smart Sensors for disease- and tissue-specific gene therapy, and with Bluerock Therapeutics LP (acquired by Bayer AG) for the use of Smart Sensors and Regulator Dials for regenerative medicines.

Our Gene Circuit Application to Allogeneic, NK Cells for Oncology

Our initial pipeline focus is on the application of our gene circuit platform technologies towards improving the treatment of specific oncology indications. Our most advanced product candidates are allogeneic, gene circuit-engineered

CAR-NK

cells. We have chosen to engineer NK cells with our gene circuits based on our belief that NK cells confer the following advantages in relation to other potential immune cell types in oncology:

•

Innate Killing:

NK cells naturally carry multiple activating and inhibitory receptors that enable them to innately kill tumor cells while sparing healthy tissues. Furthermore, NK cells have been engineered with CARs to enhance their targeted killing activity. We leverage these features to create Logic Gated

CAR-NKs,

such as OR GATE

CAR-NKs

that enhance the killing of heterogeneous tumors and NOT GATE

CAR-NKs

that spare healthy cells from undesired toxicity and thereby potentially improve

on-target,

on-tumor

killing.

•

Immune Activation:

NK cells have been shown to support robust activation of anti-tumor immune pathways via proinflammatory cytokine and chemokine secretion. We leverage this feature with our

221

Table of Contents

Multi- Arming gene circuits to further improve their ability to trigger endogenous, complementary anti-tumor activity by engaging the rest of the tumor immunity cycle.

•

Validated Clinical Activity and Tolerability:

Allogeneic, as in healthy donor-derived,

CAR-NK

cells have been recently shown in the clinical setting to have the potential to promote effective anti-tumor activity along with low risks of graft versus host disease, or GvHD, severe cytokine release syndrome, or CRS, and neurotoxicity.

•

Broad Patient Access:

We have established proprietary protocols to derive NK cells from healthy donors, manufacture them at scale with a projected low cost, and cryopreserve them with high retained viability post-thaw. As a result, we believe that

CAR-NK

cells have the potential to be broadly accessible to patients as they may be delivered rapidly to patients in an

off-the-shelf

manner and in an outpatient setting.

Our Calibrated Release (cr) Technology

Current technologies for arming immune cells with cytokines are limited to either expressing the fully secreted natural form of the protein to support trans- or paracrine signaling, or expressing a membrane-tethered version to promote

cis-

or autocrine signaling. As a result, these first-generation constructs are unable to efficiently stimulate the engineered cell product and surrounding immune cells, such as those cells from the endogenous immune system, at the same time.

We have created a novel engineered protein technology called calibrated release (cr). We used this approach to optimize

IL-15

signaling in our

CAR-NK

platform. Our

crIL-15

engineered cytokine is tethered to the NK cell via a cleavable linker that can be cut off by a ubiquitously expressed protease on the cell surface of NK cells. The rate of linker cleavage can be calibrated by engineering the sensitivity of the cleavable linker sequence to the cell surface protease, enabling us to tune the ratio of membrane-tethered versus fully secreted protein. This platform is generalizable to other proteins, including other cytokines like

IL-12.

We Are Building Manufacturing Capabilities That May Enable Production of

Off-The-Shelf

Cell Therapies

Internal manufacturing capabilities are central to our business strategy, since they can enable us to control the quality and supply of our allogeneic

CAR-NK

cell therapies for clinical studies and ultimately commercialization. A key advantage of allogeneic cell therapies, versus autologous products that use each patient’s own cells, is the ability to manufacture large batches of drug product from healthy donor cells that can be produced in advance of clinical use, and then stored in frozen vials. Upon commercialization, we expect to be able to make our cell therapies, if approved, broadly accessible in an

off-the-shelf

manner to cancer patients.

Our corporate headquarters is located in South San Francisco, CA, where we lease approximately 40,000 square feet of research and development and corporate office space. In this location, we have approximately 10,000 square feet dedicated to manufacturing development labs. We have established research and development teams with extensive experience in cell and gene therapy manufacturing operations, including vector process development, cell process development, analytical development, quality control and quality assurance. In June 2021, we signed a lease agreement for a property in Alameda, California and have commenced construction of a Current Good Manufacturing Practices, or cGMP, facility to support clinical and commercial-scale manufacturing of multiple allogeneic

CAR-NK

cell product candidates.

This manufacturing facility is being designed as a customized

end-to-end

manufacturing solution to give us the ability to isolate NK cells, engineer these cells with proprietary gene circuits, perform cell culture expansion in large batches, and cryopreserve and store the final cGMP products. We anticipate that this facility will become operational in time to support initial clinical trials for our lead product candidates. We plan to leverage the latest

222

Table of Contents

cell therapy manufacturing technologies as we strive to optimize quality, maximize scalability and minimize cost. Our initial manufacturing efforts will focus on our two lead product candidates,

SENTI-202

and

SENTI-301.

We expect to complete the first stage of construction for our cGMP manufacturing facility and present an overview of our clinical-scale GMP manufacturing process for gene-circuit-engineered NK cells at key technical conferences in 2022.

We may also leverage our manufacturing facility to expand the application of our gene circuit technology to biomanufacturing in partnership with one or more third parties.

Our experienced manufacturing and process development team has established an innovative process with the potential for efficient and scalable production of our allogeneic

CAR-NK

cell product candidates. Critical aspects of the cell manufacturing process include the ability to perform the four key steps in the

CAR-NK

cell manufacturing process as outlined below:

Step 1: Source, Isolate and Bank Purified NK Cells as Starting Cells:

Starting Cells are obtained from enriching and isolating NK cells from qualified healthy donors.

Step 2: Genetically Engineer Starting Cells with Gene Circuits:

We genetically modify our NK cells through a viral vector transduction process focused on enhancing gene circuit expression while minimizing impacts on compromising cell viability or cell expansion.

Step 3: Expand and Scale

CAR-NK

Cells:

Our expansion process is designed to generate large numbers of final product doses per manufacturing batch.

Step 4: Formulate and Cryopreserve

CAR-NK

Cells:

For storage and distribution, we will formulate and cryopreserve our final product to retain viability, persistence and cytotoxic function post-thaw for

off-the-shelf

use.

Our goal is to become an industry leader in the cell and gene therapy landscape. We are pursuing this goal by advancing our gene circuit platform to discover, develop, manufacture and globally commercialize new classes of cell and gene therapies across therapeutic areas and modalities.

We aim to provide smarter medicines to patients, and to execute on this strategy we will continue to build on our extensive capabilities by:

•

•

Maximizing the commercial potential of our gene circuit platform technologies via strategic collaborations.

The Need for Synthetic Biology-Based Gene Circuits

For the human body to maintain proper function, cells constantly sense and interpret a variety of inputs, or biological signals, to produce outputs, or biological responses. Diseases emerge when the balance between these biological inputs and outputs become inadequate or inappropriate to maintain a healthy state. Furthermore, diseases can evolve or mutate to evade the human body’s natural defense mechanisms that normally serve as a check against these imbalances. Thus, many diseases progress when the intrinsic ability of cells in the human body to rebalance healthy physiology is insufficient or becomes overactive. We believe that programming cells to better sense and react to disease environments has the potential to enhance our ability to treat diseases and restore healthy phenotypes.

Traditional medicines, such as small molecules and biologics, typically target proteins and block their function. We consider these medicines to be static because they have a predefined activity around a single mechanism of action that cannot be modulated once administered. With some exceptions, most traditional medicines primarily treat disease symptoms or

sub-optimally

address the underlying disease biology, thus failing to achieve durable cures. In addition, some traditional medicines have

on-target,

off-tissue

effects that limit therapeutic windows and cause safety concerns.

There have been remarkable advances in technologies for reading (sequencing) and writing (synthesizing) DNA over the past few decades. These technologies have aided the biopharmaceutical industry in identifying disease mechanisms and have enabled the programming of cell and gene therapies.

As transformative as the early generations of cell and gene therapies have been, they are currently confined to narrow applications and have been proven effective against only a few monogenic diseases and hematological malignancies. These current approaches are limited to sensing and correcting single disease signatures while providing little control over their dosage, timing or localization. Thus, diseases that are dynamic or multifactorial cannot be readily addressed by existing cell and gene therapy products.

Using our gene circuits, we believe we can design more intelligent cell and gene therapies that (i) can precisely target heterogeneous diseases using Logic Gating, (ii) can be Multi-Armed with complementary payloads to overcome disease evasion, (iii) can be controlled

in vivo

using Regulator Dials to overcome narrow therapeutic windows and (iv) are equipped with Smart Sensors that dynamically detect disease environments.

225

Table of Contents

We believe that by leveraging synthetic biology to engineer gene circuit-enabled cell and gene therapies, we will be able to overcome the shortcomings of the early generations of these genetic medicines

Our Platform: The Opportunity for Gene Circuits

We believe that our gene circuit platform technologies are modality-agnostic and can be deployed in any cell and gene therapy product candidate to improve efficacy, safety and control. Fundamentally, gene circuits reprogram cells to sense key biological signals, compute based on this information and dynamically respond with multiple therapeutic outputs. In contrast to existing single-target or static medicines, this sense-compute-respond paradigm has the potential to enable precise and highly active medicines that can address the complex and dynamic mechanisms underlying important diseases.

Our Gene Circuit Platform Technologies

In our pursuit to create a new generation of smarter medicines, we have built a toolbox of proprietary gene circuit platform technologies that we believe may enhance the risk benefit paradigm of cell and gene therapy products. We are initially focused on four core categories of gene circuits to develop our current and future programs: (i) Logic Gating, (ii) Multi-Arming, (iii) Regulator Dials and (iv) Smart Sensors. Each of our gene circuit platform technologies is designed to confer greater clinical and therapeutic activity, precision and control to cell and gene therapies.

We believe that our core gene circuit platform technologies may enable us to engineer smarter medicines and can be categorized as follows:


		Logic Gating: Logic Gating gene circuits are designed to enable cell and gene therapies to control their therapeutic activity in response to the presence or absence of multiple disease biomarkers. Below are examples of Logic Gates applied to cancer, although Logic Gating may be applied to various other disease indications as well.
				NOT GATE: NOT GATE gene circuits are designed to widen the therapeutic window by enabling effective killing of cancer cells while preserving healthy cells. The NOT GATE functions by recognizing Safety Antigens, or antigens that are selectively expressed on healthy cells and not on cancer cells, thus limiting on-target, off-tumor killing. By protecting healthy cells, the NOT GATE has the potential to enable more effective on-target, on-tumor killing of tumor cells that express Tumor-Associated Antigens. Generally, existing cancer drugs target only a single antigen, which means they can only be effectively and safely used in situations where that antigen is uniquely expressed on tumors and not in healthy cells, or where the on-target, off-tumor effects are tolerable.
				OR GATE: OR GATE gene circuits are designed to address tumor heterogeneity and limit antigen escape. The OR GATE functions by killing tumor cells that express any one of multiple antigens. Generally, current medicines are unable to address more than one target at a time and are thus susceptible to tumor evasion.
				AND GATE: AND GATE gene circuits require that multiple targets be present at the same time to trigger killing of cancer cells, which may enhance the specificity of on-target, on-tumor activity. Generally, conventional therapies only recognize a single antigen for their activity, which can result in a lack of specificity.
		Multi-Arming: Multi-Arming gene circuits are designed to incorporate multiple payloads into a single cell or gene therapy product. These gene circuits are intended to activate various biological pathways in complementary ways to prevent diseases from evading single-target treatments, and thereby potentially improve treatment efficacy. Existing combination therapies that target complex

226

		diseases require the application of multiple individual drugs, which is difficult due to research, clinical development, regulatory and pharmacology barriers.
		Regulator Dial: Regulator Dial gene circuits are designed to enable the precise tuning of therapeutic activity from a cell or gene therapy product. For example, this can be implemented by regulating therapeutic payload expression in response to varying concentrations of FDA-approved drugs. Regulator Dials are expected to enable the exogenous regulation of next-generation cell and gene therapies even after they have been delivered in vivo . Existing cell and gene therapies cannot be modulated once they have been delivered into patients.
		Smart Sensor: A Smart Sensor is a gene circuit, or combination of gene circuits, designed to precisely detect cell type or disease environments, and thus distinguish between the “disease state” and “healthy state.” For example, Smart Sensors can be engineered to detect whether certain conditions, or disease biomarkers, are present before responding with a specific therapeutic response. Conventional medicines are generally unable to dynamically change their behavior in response to cell or disease specific conditions.

We believe we can rationally combine any one of these four gene circuit platform technologies to strategically customize therapeutics to outmaneuver complex diseases.


		Logic Gating

Logic Gating gene circuits are designed to enable cell and gene therapies to control their therapeutic activity in response to the presence or absence of multiple disease biomarkers. This capability has the potential to enable more accurate and efficient targeting of heterogeneous diseased cells while sparing healthy ones. Our initial product candidates for oncology will utilize our NOT GATE and OR GATE gene circuit technology. Furthermore, we believe this technology can be utilized across a broad range of oncology indications. To this end, we have established a proprietary Tumor-Associated Antigen and Safety Antigen Paired Discovery Platform that enables the expansion of our Logic Gating approach against novel Tumor-Associated Antigen and Safety Antigen pairs across multiple cancer indications.

The figure below illustrates the behavior of our Logic Gating gene circuit technologies in

CAR-NK

cells:

		NOT GATE

Background: The Need for Precision Targeting

The expression of a single CAR in T cells or NK cells can redirect them to kill cancer cells that express a specific surface antigen. This technology has led to breakthrough therapies for B cell malignancies and multiple myeloma, where targeting of tissue-lineage antigens – CD19 or B Cell Maturation Antigen, or BCMA – rather than Tumor-Associated Antigens, is tolerated. Beyond these initial applications, the lack of uniquely specific tumor antigens presents a great challenge since

on-target,

therapies. Similar limitations are faced by monoclonal antibodies and antibody-drug conjugates that rely on a single target to discriminate cancer cells from healthy ones.

Our Logic Gating Solution: NOT GATE

The application of

CAR-immune

cells may be broadened to many cancer types if recognition of a Safety Antigen that is selectively expressed on healthy cells, but not on cancer cells, could selectively block killing against the healthy cells. We believe this feature enables a widened therapeutic window and aggressive treatment of cancers with the potential for enhanced efficacy and reduced risk of undesirable side effects, as well as the expansion of cell therapies into cancer indications where there are no ideal Tumor-Associated Antigens.

As shown in the figure below, we have engineered NK cells with a synthetic NOT GATE gene circuit, where an activating CAR, or aCAR, can drive the killing of cancer cells presenting an activating, Tumor-Associated Antigen, shown in green, while an inhibitory CAR, or iCAR, can suppress cytotoxicity against normal healthy cells that express both the activating Tumor-Associated Antigen and a Safety Antigen, shown in purple.

Selected NOT GATE

Proof-of-Concept

Data

Our NOT GATE is implemented with iCARs, which consist of a Safety Antigen-binding domain and a functional intracellular domain derived from the cytoplasmic tails of inhibitory

co-receptors

containing immunoreceptor tyrosine-based inhibitory motifs, or ITIMs, which are selected from a library of ITIMs upon testing and evaluation. When a Logic Gated

CAR-NK

cell encounters a target cell and associates with its cell surface antigens, the aCAR and iCAR “sense” these inputs and provide activating or inhibitory signals into the

228

Table of Contents

Logic Gated

CAR-NK

cell, respectively. Specifically, engagement of the aCAR alone with an activating, Tumor-Associated Antigen triggers an activating signal cascade in the

CAR-NK

cells that release cytotoxic mediators to kill the cancer cells. When the iCAR recognizes a certain Safety Antigen that is preferentially expressed on healthy cells, an inhibitory signal cascade is triggered in the

CAR-NK

cells to block the cytotoxic response, thus sparing the healthy cells.

In vivo

functional demonstration of our NOT GATE gene circuit is illustrated in the figure below. A group of mice that received xenotransplantation of model Healthy Cells and Cancer Cells at a ratio of 50:50 were treated with NOT GATE

CAR-NK

cells targeting either a control Safety Antigen not present on the model Healthy Cells, labeled as Control

CAR-NK

cells, or a Safety Antigen on the model Healthy Cells, labeled as the NOT GATE

CAR-NK

cells. The Control

CAR-NK

cells indiscriminately killed both the model Healthy Cells and Cancer Cells in mice. Conversely, the NOT GATE

CAR-NK

cells selectively killed the Cancer Cells, while sparing the model Healthy Cells. Further analysis showed that treatment with NOT GATE

CAR-NK

cells resulted in significant enrichment of Healthy Cells in these mice, up from 50% at baseline to approximately 95% after treatment. This data demonstrates that the NOT GATE

CAR-NK

cells have the potential to spare model Healthy Cells while maintaining killing of model Cancer Cells

in vivo

Future Areas of Applications and Alternate Gene Circuits

We believe the enhanced precision enabled by our NOT GATE gene circuit may improve the therapeutic window, and thus the potential efficacy and safety, of our product candidates against the cancer types in our pipeline. Furthermore, the NOT GATE has the potential to significantly increase the applicability of

CAR-NK

cells against a wide range of liquid and solid tumors that currently do not have ideal Tumor-Associated Antigen targets and are thus currently unaddressed.


		OR GATE

Background: The Need for Targeting Multiple Antigens

Many cancers are heterogeneous, making it difficult to treat them by only targeting a single antigen. For example, the development of targeted AML treatments is difficult due to more than 200 types of chromosome

229

Table of Contents

translocations and mutations having been identified in patients. Thus, therapies targeting a single

AML-associated

antigen are often insufficient to kill all of the tumor subsets, including both AML LSCs and blasts. Consequently, most AML patients treated with these therapies die from disease relapse and progression due to incomplete therapeutic activity. Additionally, due to the highly mutagenic nature of cancer cells, targeting single antigens allows for cancers to more easily escape or acquire resistance to treatment. For example, while recent triumphs of CD19-directed autologous

CAR-T

therapies have brought renewed hope to patients with relapsed/refractory B cell malignancies, up to 50% of patients with

pre-B

cell acute lymphoblastic leukemia, or ALL, suffer disease relapse within twelve months after treatment. Many of those patients who relapse toward the latter end of the twelve-month period have cancers that have been associated with loss of the CD19 epitope.

These clinical observations demonstrate the potential benefit of developing therapeutics that are capable of simultaneously targeting multiple Tumor-Associated Antigens across heterogeneous cancers using OR GATE gene circuit technology.

Our Solution and Selected

Proof-of-Concept

Data: OR GATE

OR GATE gene circuits are designed to simultaneously target multiple Tumor-Associated Antigens.

As an example of our OR GATE gene circuits, we have evaluated two forms of OR GATE gene circuits to support our

SENTI-202

product candidate, a bicistronic dual CAR architecture and a bivalent CAR architecture.

Bicistronic dual CAR:

The bicistronic dual CAR is designed to express two CAR molecules directed against FLT3 and CD33, respectively, two Tumor-Associated Antigens where one or both are expressed in 95% of AML patients. Because CD33 is highly expressed on AML blasts, and FLT3 is highly expressed on LSCs,

SENTI-202

offers the potential for elimination of both AML tumor subsets. Using our DBTL Engine, we systematically optimized our OR GATE gene circuit to achieve highly efficient expression of both CAR constructs, as shown in the figures below from top to bottom. Functional

proof-of-concept

of the OR GATED

CAR-NK

cells targeting AML is shown in the

SENTI-202

pipeline discussion.

Bivalent CAR:

Bivalent CARs are directed against FLT3 and CD33. The bivalent CAR is a single-chain molecule containing two extracellular binding domains, thus allowing for OR GATE targeting with a single construct. In preclinical mouse models, our FLT3/CD33 bivalent CAR constructs demonstrated significant tumor killing across leukemic cell lines, such as

MV4-11,

SEM, and

HL-60,

with differential expression levels of FLT3 and CD33 on their cell surfaces.

		AND GATE

Our third Logic Gate gene circuit technology is the AND GATE. AND GATE gene circuits require that multiple targets be present at the same time to trigger killing of cancer cells, which may enhance the specificity of

on-target,

on-tumor

activity. Generally, conventional therapies only recognize a single antigen for their activity. We can implement AND GATE gene circuits in multiple formats, including multiple CARs that activate cancer cell killing when two Tumor-Associated Antigen targets are present simultaneously or multiple Smart Sensors that activate gene therapies when two disease-specific promoters are active simultaneously. For example, we have designed cancer gene therapy product candidates that integrate two cancer-specific promoters with an AND GATE to express cytokines, T cell engagers, chemokines and

anti-PD1

antibodies in order to trigger powerful and specific anti-cancer responses in mouse models of cancer.


		Multi-Arming

Multi-Arming gene circuits incorporate multiple payloads into a single cell or gene therapy product. These gene circuits are intended to activate various biological pathways in complementary ways to prevent diseases from evading single-target treatments, and thereby improve treatment efficacy. Existing combination therapies that target complex diseases require the application of multiple individual drugs, which is difficult due to research, clinical development, regulatory and pharmacology barriers.

Background: The Need for Targeting Multiple Biological Pathways

Many diseases are difficult to treat since they result from the dysfunction of numerous biological pathways, or they evolve strategies to evade single-target therapies. Combination therapies involving multiple distinct drugs are being used to tackle this problem, but manufacturing, developing and delivering multiple individual drugs into the body is challenging.

231

Table of Contents

Our Gene Circuit Solution: Multi-Arming

We believe our Multi-Arming gene circuits can be used to create a single cell or gene therapy product candidate that includes multiple payloads capable of combating multiple disease pathways more effectively. These Multi-Arming gene circuits have the potential to simplify the manufacturing, regulatory and delivery challenges associated with conventional combination therapies. Multi-Arming gene circuits can be controlled by any of our other gene circuit technologies, including Regulator Dials and Logic Gates, to achieve conditional therapeutic activity.

Selected Multi-Arming

Proof-of-Concept

Data

We have assembled a library of immune-stimulatory payloads—such as cytokines, chemokines and enzymes—that have the potential to trigger anti-tumor responses. As illustrated by the figure below, we leveraged our DBTL Engine to optimize the expression of various immune stimulatory payloads in

CAR-NK

cells, and test the effects of single-armed versus multi-armed

CAR-NK

cells for their anti-cancer activity. .

232

Table of Contents

The figure below illustrates an example of the benefits of multi-arming.

CAR-NK

cells were engineered to express either a single cytokine, or multi-armed with both cytokines. These engineered

CAR-NK

cells were

co-cultured

with fluorescently labeled tumor cells, and

in vitro

tumor cell killing was measured over 5 days. While unarmed

CAR-NK

cells, and single-armed

CAR-NK

cells, shown by the purple and red lines in the figure, were able to control and reduce tumor cell growth, the multi-armed

CAR-NK

cells, shown by the teal line in the figure, had greater anti-tumor activity. These results can also be observed by representative fluorescent tumor cell images, shown on the right hand side of the figure, where enhanced tumor killing by the multi-armed

CAR-NK

cells led to reduced number of tumor cells.


		Regulator Dial

Regulator Dial gene circuits are designed to enable the precise tuning of therapeutic activity from a cell or gene therapy product. For example, this can be implemented by regulating therapeutic payload expression in response to varying concentrations of

FDA-approved

drugs. Regulator Dials are expected to enable the exogenous regulation of next-generation cell and gene therapies

in vivo

even after they have been delivered. We have generated numerous Regulator Dial gene circuits that can be controlled by a variety of

FDA-approved

small molecule oral drugs, and that can implement various control behaviors, such as ON switches, OFF switches and rheostats.

Background: The Need for Dynamic Regulation

Existing cell and gene therapies cannot be regulated once they are delivered into the patient. This lack of

in vivo

control makes it difficult to control dosing within the ideal therapeutic window. This problem makes it challenging to expand cell and gene therapies to many disease indications and to engineer these products to have increased potency and safety. As a result, gene therapies have focused on indications where constitutive expression is acceptable, rather than diseases where expression of the therapeutic payload must be regulated within a specific range or be toggled on and off over a period of time. As another example,

CAR-T

cell therapies for oncology have exhibited clinical toxicity due to lack of control post-infusion.

The efficacy of adoptive cell therapies in solid tumors is hampered by the poor persistence and dysfunction of these cell therapies in the immunosuppressive tumor microenvironment. Inflammatory cytokines, such as

IL-12,

have been shown in preclinical studies to enhance

CAR-mediated

effector functions and stimulate the

233

Table of Contents

innate immune response to further support tumor killing. However, clinical trials involving systemic use of

IL-12

have shown severe unexpected toxicity, limiting its clinical application. Overexpressing

IL-12

from adoptive T cell therapies using a poorly regulated promoter has also resulted in significant clinical toxicities. Beyond toxicity issues, persistent stimulation by inflammatory cytokines has been associated with cell exhaustion and may limit anti-tumor efficacy. Thus, a mechanism to dynamically regulate cytokine production by armored

CAR-immune

cells could enable enhanced anti-tumor activity without triggering unacceptable levels of toxicity in patients.

Our Gene Circuit Solution: Regulator Dial

One example of our Regulator Dial gene circuit technology is a system designed to regulate gene expression via

FDA-approved

orally dosed nonstructural protein 3, or NS3, inhibitors. As shown in the figure below, this Regulator Dial consists of a synthetic drug-regulated transcription factor and a synthetic promoter responsive to this regulated transcription factor. In the absence of the drug, the transcription factor is inactive, and no therapeutic protein is produced from the engineered cells. In the presence of the drug, the small molecule triggers expression of the therapeutic protein in a dose-dependent manner—effectively, the Regulator Dial “computes” the level of induction based on the concentration of the drug. Key features of the Regulator Dial, such as (i) basal and maximal expression levels, (ii) thresholds for activation and (iii) input-output gain, can be tuned by our DBTL Engine.

234

Table of Contents

Selected Regulator Dial

Proof-of-Concept

Data

Leveraging our DBTL Engine, our

NS3-based

Regulator Dial was systematically engineered to improve its sensitivity to drug concentration. Optimization of various elements in the Regulator Dial improved the drug sensitivity by approximately tenfold. As illustrated by the figure below, we evaluated the drug sensitivity of our Regulator Dial gene circuit to control the expression of the potent immune effector

Il-12.

Specifically, this enhanced Regulator Dial gene circuit was triggered at concentrations as low as 0.01 µM of the NS3 inhibitor, grazoprevir, well below the known drug Cmax in humans of 0.23 µM. Thus, we believe that this system could enable control of therapeutic protein production at clinically achievable drug concentrations in a dose-dependent fashion.

We have further validated our Regulator Dial gene circuits

in vivo

. Using a murine model to evaluate induction of

IL-12

production, Regulator Dial gene circuit-engineered cells were injected intravenously into immunodeficient mice on Day 0. Induction of

IL-12

expression in mice was evaluated by treatment with either vehicle control or grazoprevir (GRZ in the figure below). Significant

IL-12

induction was observed in mice treated with grazoprevir on Day 4. Upon withdrawal of grazoprevir after Day 4,

IL-12

returned to basal level.

235

Table of Contents

Future Areas of Applications and Alternate Gene Circuits

Beyond the

NS3-based

Regulator Dial, we have developed and continue to optimize other Regulator Dials. These include Regulator Dials that are controlled by other orally dosed compounds that are

FDA-approved

or chemicals that are otherwise known as safe, which have differing pharmacology profiles and tissue biodistribution, such as into the central nervous system. These different Regulator Dials can be customized for a variety of cell and gene therapy applications. Conversely, we have created Regulator Dials that are dialed down in response to increasing concentrations of the drug. For example, we have made various versions of Regulator Dials that can be regulated by different small molecule drugs, such as Hepatitis C Virus (HCV) protease inhibitors, Immunomodulatory imide drugs, or IMiDs, such as thalidomide and its analogs, and tamoxifen.


		Smart Sensor

A Smart Sensor is a gene circuit, or combination of gene circuits, designed to precisely detect cell type or disease environments, and thus distinguish between the “disease state” and “healthy state.” For example, Smart Sensors can be engineered to detect whether certain conditions, or disease biomarkers, are present before responding with a specific therapeutic response. Conventional medicines are generally unable to dynamically change their behavior in response to cell or disease specific conditions.

Diseases change over time and location in the body. Existing therapies are often unable to dynamically change their behavior in response to disease conditions or concentrate their activity only to specific places. Smart Sensors can be designed to sense diverse biomarkers that are specific to disease or cell states, including cell-surface antigens, soluble disease markers, metabolites, transcription factors, microRNAs and others. For example, we have created artificial receptors that are displayed on the surface of engineered cells and activate gene expression within these cells when they encounter specific cytokines or small molecule chemicals. We have also designed gene regulatory elements such as promoters and RNA elements that respond to specific intracellular signals, such as transcription factors and microRNAs.

236

Table of Contents

The figure below illustrates how our Smart Sensor gene circuit technology can be used to design synthetic promoters to enable gene therapies that are selectively activated in diseased cells by detecting disease-specific transcription factors:

Background: The Need for Novel Sensors in Smart Medicine

Cell and gene therapies have long held out the promise of curing a myriad of diseases, including cancer and genetic disorders. These therapies are generally comprised of three components: (i) the vector, which is used to deliver the transgene into cells; (ii) the promoter, which is a regulatory DNA sequence that drives expression of the transgene; and (iii) a transgene, which is the therapeutic payload.

While early successes in the field have led to recently approved gene therapies, it remains challenging to precisely target gene expression only in diseased cells. This is an important limitation since many genetic disorders require controlled or targeted activity in certain cell types in order to correct diseases while preventing undesirable side effects. Similarly, in cancer gene therapy, it is important to achieve selective killing in cancer cells while sparing healthy tissues. Engineering viral vectors that are biased toward specific cell types is limited by the availability of a unique feature on the outside of the target cell that a viral vector can harness. Additionally, many of the promoters used in current gene therapies are not disease, cell or tissue specific and thus lack the ability to dynamically regulate therapeutic protein production in response to the disease state or location.

Our Smart Sensors Solution: Cell Type or Cell State Specific Conditional Synthetic Promoters

Our solution to address these limitations is to construct Smart Sensors that are selectively activated by cell type or cell state. For example, these Smart Sensors are synthetic promoters that sense internal control mechanisms that cells already possess, such as transcription factors. Transcription factors modulate regulatory

237

Table of Contents

elements encoded in the DNA sequence of promoters to direct gene transcription to occur in a specific cell type, or even a specific cell state.

We have established, and continue to scale, our powerful DBTL Engine to discover highly potent and selective synthetic promoters. As shown in the figure below, our iterative high-throughput process utilizes advanced computational approaches, such as machine learning, to discover these promoters. In the first stage, we perform computational analyses of public and proprietary gene expression datasets to identify transcriptional regulatory elements that are active in a desired, or

on-target,

cell type and inactive in one or more undesired, or

off-target,

cell types. Based on these analyses, we computationally design diverse libraries of synthetic, compact promoters that can be synthesized in parallel. For example, we can design libraries containing more than 10,000 promoters that are 200 to 400 base pairs in size, which is significantly smaller than currently used promoters in gene therapies. In the second stage, we perform high-throughput assays to quantify the activities of these promoters in the

on-target

cell types versus the

off-target

cell types using next-generation sequencing. This enables us to identify synthetic promoters that are both highly active and specific for the

on-target

cells. If further optimization is needed, the output of these screens provides a rich source of proprietary data for the machine-learning-enhanced design of additional synthetic promoter libraries, representing the third stage of the process.

238

Table of Contents

Selected Smart Sensor

Proof-of-Concept

Data

We have used this high-throughput design platform to generate synthetic promoters for diverse gene and cell therapies. For example, we designed and evaluated, in a high-throughput manner, thousands of synthetic promoters to identify candidates that achieve strong differential expression in breast cancer cells versus healthy breast cells. As shown in the figure below, we were able to validate promoters with very strong selectivity for human breast cancer cells, labeled as Cancer Cell Synthetic Promoter in the figure, versus the healthy breast cells, by up to

~1,000-fold.

This level of selectivity is much greater than what we have observed from other cancer-specific promoters of which we are aware. In addition, we also identified healthy-cell-specific promoters, labeled as Healthy Cell Synthetic Promoter in the figure, that are highly selective for healthy breast cells compared to breast cancer cells.

Future Areas of Applications and Alternate Gene Circuits

The concept of Smart Sensors that sense disease-specific or tissue-specific transcriptional states is broadly applicable across various therapeutic areas outside of oncology. For example, we believe we can apply our Smart Sensor design platform to create promoters that are selectively activated in certain cells and tissues, such as neurons and muscle. We have also designed microRNA-responsive Smart Sensor elements into mRNA sequences that achieve selective gene expression in desired cells. These Smart Sensors have the potential to enable gene therapies with maximal

on-target

activity and minimal

off-target

side effects, thus increasing the therapeutic window of our product candidates.

We have also created artificial receptor architectures that can detect extracellular or cell-surface proteins beyond traditional CARs. These artificial receptor Smart Sensors can be programmed to bind to soluble disease markers, such as cytokines, metabolites, hormones and others, and then modulate gene transcription within cells to drive the appropriate therapeutic response.

We Believe Our Gene Circuits May Have Broad Applicability in Multiple Treatment Modalities and Disease Areas

We believe that our gene circuit platform may have broad applicability across treatment modalities and disease areas.

including HSCs,

Disease Areas

Our gene circuits can be customized to address many aspects of disease biology. We have demonstrated and published on applications of gene circuits across many different

in vivo

disease models. Thus, we believe that our gene circuit platform technologies can be used against a broad range of diseases that span therapeutic areas such as oncology, immunology, genetic diseases, neurology, cardiology, metabolic diseases, ophthalmology and regenerative medicine.

The following figure presents our perspective on how our gene circuit technologies can be utilized across modalities and corresponding therapeutic areas:

We believe the speed, quantity and quality by which we can design multiple types of gene circuits, resulting in thousands of functional gene circuits engineered to date, is unique to our platform. Our gene circuits are engineered by an expert team of synthetic biologists informed by proprietary bioinformatics and our internal gene circuits knowledge database. We also leverage machine learning approaches to continually enhance the design of such gene circuits based on data generated through testing in our

Our Calibrated Release (cr) Technology

In clinical trials run by other parties unaffiliated with Senti Bio,

IL-15

has been shown to improve persistence and maintain a cytotoxic phenotype in NK cells. Another clinical trial of a

CAR-NK

cell with

IL-15

reported clinical efficacy without a systemic increase in circulating

IL-15

or toxicity at assessed doses and time points. Previously published studies of tumor resident NK cells collected from HCC patients have also shown that

IL-15

can restore NK cell dysfunctions.

We have created a novel engineered protein technology called calibrated release (cr). We used this approach to optimize

IL-15

Our Pipeline and Product Candidates

We are advancing a broad pipeline of gene circuit-enabled product candidates focused on three distinct categories: (i) allogeneic

CAR-NK

cells for oncology, (ii) gene therapies for tissue-directed targets and (iii) cell therapies for regenerative medicines. Our most advanced programs are allogeneic

CAR-NK

product candidates designed to improve the therapeutic outcome of certain oncology indications:

SENTI-202,

SENTI-301

and

SENTI-401.

Our pipeline chart is as follows:

Table of Contents

SENTI-202

for the Potential Treatment of Acute Myeloid Leukemia

Overview

We are developing our

SENTI-202

product candidate as a Logic Gated (OR + NOT) allogeneic

CAR-NK

cell therapy designed to target and eliminate AML cells while sparing the healthy bone marrow. We are engineering

SENTI-202

to express a bivalent CAR as an OR GATE directed against the Tumor-Associated Antigens, FLT3 and CD33, where one or both are expressed in 95% of AML patients. FLT3 is highly expressed on LSCs, while CD33 is highly expressed on AML blasts. AML is a heterogeneous disease composed of both AML LSCs and blasts. Thus, we believe that targeting FLT3 OR CD33 will enhance the overall killing activity against diseased cells in AML. However, FLT3 is also expressed on HSCs in the bone marrow. In order to spare FLT3-expressing healthy HSCs, we have further engineered

SENTI-202

with a NOT GATE gene circuit comprised of an iCAR targeted against EMCN. EMCN is a Safety Antigen with high expression on HSCs and low expression on AML LSCs and blasts. We believe this NOT GATE gene circuit could allow

SENTI-202

to eliminate LSCs that cause relapse while preserving the patient’s HSCs. Further,

SENTI-202

is engineered to express our proprietary

crIL-15

effector to promote persistence and more durable antitumor functions. This proprietary product profile has the potential to drive towards a cure for AML without the need for a bone marrow transplant by enabling killing of diverse AML cells while sparing HSCs that regenerate the blood and the immune systems.

In 2022, we plan to present

IND-enabling

pharmacological data at key scientific conferences, seek feedback from the FDA through a

pre-IND

meeting, and apply for Orphan Drug Designation. In 2023, we plan to submit an IND application to support the clinical evaluation of

SENTI-202.

Acute Myeloid Leukemia: an Unmet Medical Need

Almost 10% of new cancer cases in the United States each year are hematologic malignancies, including leukemia, lymphoma and myeloma. AML is a type of acute leukemia characterized by an accumulation of malignant immature white blood cells. It is the most common type of acute leukemia in adults, constituting 80% to 85% of cases, and is the second most common—as well as the deadliest—in children. Due to the absence of highly efficacious therapies, AML has the lowest five-year survival rate among all leukemias at just 28.7%. Since the incidence is highest among the elderly, we expect cases and economic burden will continue to rise as the general population ages. According to Dieguez et al., costs for the three years following AML diagnosis can reach $800,000 per patient.

243

Table of Contents

Conventional therapy for AML generally involves remission induction therapy, followed by consolidation (post-remission) therapy, in which chemotherapy is used with stem cell transplantation to prevent disease recurrence. For remission induction, treatment options include cytotoxic chemotherapy, radiation therapy and targeted therapies, such as monoclonal antibodies and small molecule inhibitors of disease pathways, with the aim of achieving fewer than 5% blast cells in the bone marrow, blood cell counts within normal limits and no signs or symptoms of disease. Unfortunately, 10% to 40% of patients are unable to achieve these complete remission targets despite intensive induction therapy, and conventional therapies have failed to significantly improve the long-term survival of patients for decades. Moreover, relapse of disease in patients with AML is a major issue and remains a difficult clinical challenge, with approximately 70% of patients relapsing within three years.

Development of targeted AML treatments is difficult due to the fact that the disease is highly heterogeneous, with more than 200 types of chromosome translocations and mutations having been identified in AML patients. Therapies targeting a single Tumor-Associated Antigen are therefore often insufficient to kill all of the cancer cell subsets in AML, leading to eventual disease relapse. To drive patients into deeper remissions and prevent relapses, therapies designed to target multiple AML antigens are needed. Additionally, recent studies suggest relapse is associated with the less targeted AML subpopulation of LSCs. Thus, the development of therapies targeting AML LSCs is sorely needed, but this has been challenging since LSC targets are often expressed on healthy cells, such as HSCs, leading to

on-target,

off-tumor

treatment-induced toxicities.

CAR Cell Therapy for AML

The therapeutic administration of CAR cell therapies has considerably advanced the treatment of certain cancers, such as ALL. However, the successes of CAR cell therapies have not yet translated to successful treatment of AML, in part due to the absence of

AML-specific

target antigens. Due to their nonrestrictive expression, most AML antigens are also expressed on healthy HSCs or myeloid cells. Thus,

on-target,

off-tumor

killing effects of the therapy may lead to the ablation of hematopoietic stem, progenitor or myeloid cells. While the B cell depletion that results from

off-tumor

killing of normal healthy cells in

CAR-T

therapy of ALL can be clinically managed,

off-tumor

killing of HSCs is unlikely to be tolerated in the case of AML treatment. Thus, the identification of antigens that enable more robust targeting of AML cells, including LSCs, along with new strategies to reduce

off-target

killing of HSCs, are critically needed to realize the promise of CAR cell therapies for AML treatment. These described challenges also extend to other potential AML therapeutic modalities, such as antibodies and bispecific T cell engagers.

The following figure illustrates the design of

SENTI-202

Logic Gating gene circuits to kill AML LSCs and blasts, while sparing healthy HSCs via (FLT3 OR CD33) NOT EMCN logic. Based on the medical community’s substantial clinical experience from autologous and allogeneic-bone marrow transplantations, we believe that protecting 10% to 20% of HSCs would be sufficient to enable hematopoietic recovery and provide clinical benefits to patients.

We have established a proprietary Tumor-Associated Antigen and Safety Antigen Paired Discovery Platform to identify complementary Tumor-Associated Antigens for the OR GATE and selective Safety Antigens for the NOT GATE. For

SENTI-202,

we applied this platform to discover the combination of the Tumor-Associated Antigens, FLT3 and CD33, and the corresponding Safety Antigen, EMCN, for application in AML.

In order to select the AML target antigens for the OR GATE gene circuit, we first established criteria for success, including: (i) expression on cell surface targetable by CAR, (ii) high expression across different AML subtypes, (iii) high expression in the critical LSC subset, (iv) little to no expression in

non-hematopoietic

tissues and (v) target combinations that yield broad coverage of AML LSCs and blast cells both among different patients and within individual patients. We utilized our Tumor-Associated Antigen and Safety Antigen Paired Discovery Platform, which leverages an internal bioinformatics database comprising greater than 10 published studies and greater than 1,300 AML patient sample datasets. Using our proprietary transcriptomics- and proteomics-based bioinformatics pipeline, we identified FLT3 and CD33 as desirable Tumor-Associated Antigens for an OR GATE gene circuit to have the potential for comprehensive

CAR-mediated

killing of AML, including AML LSCs and blasts.

As shown in the left panels of the two transcriptomic analysis figures below, our bioinformatics analyses concluded that FLT3 and CD33 are Tumor-Associated Antigens that are more highly expressed among AML LSCs and blast cells, respectively, relative to most healthy hematopoietic lineages.

As shown in the right panels of the two transcriptomic analysis figures below, these antigens are generally not expressed in normal healthy solid organ tissues. An important exception is that high-level expression of FLT3 is observed in healthy HSCs, as shown in the green box in the figure below, which is an observation consistent with published literature. In support of this observation, FLT3-directed bispecific antibodies and

CAR-T

have demonstrated bone marrow suppression in preclinical models previously described in literature. Accordingly, we believe preserving these HSCs through a NOT GATE is important to prevent bone marrow suppression during

LSC-directed

AML treatment.

Further, our internal evaluations of primary AML samples also indicated that FLT3 and CD33 were highly expressed at the protein level, in both the AML blast and LSC subsets. A representative flow cytometric analysis is shown in the figure below. The green-shaded quadrants in the figure below represent AML cells that were either FLT3 positive, CD33 positive, or both, demonstrating that the OR GATE approach could limit the number of AML cells that are not targeted by our product candidate.

Preclinical

Proof-of-Concept

Data

Leveraging our DBTL Engine, we optimized the expression of the OR GATE FLT3 and CD33 CAR constructs, as shown above in the section titled “Our Platform: The Opportunity for Gene Circuits—Logic Gating—OR GATE”. We then evaluated the ability of these OR GATE

CAR-NK

cells to kill different leukemia cell lines, including ones that have differential expression levels of the FLT3 and CD33 antigens. As shown in the figure below, our FLT3 OR CD33

CAR-NK

cells exhibited increased killing over that of the single-target

CAR-NK

cells, such as FLT3 only

CAR-NK

and CD33 only

CAR-NK

cells. Specifically, they demonstrated significantly improved killing across FLT3++ (p < 0.05) and CD33++ (p < 0.01) expressing leukemia cell lines

in vitro

, shown as FLT3++ and CD33++ bars in the figure below.

We further confirmed

in vitro

that our OR GATE

CAR-NK

cells were capable of killing primary AML cells. As shown in the right panel in the figure below, we identified primary AML samples, labeled AML#770, #857, #847, #837 and #846, with expanded blast populations by flow cytometry, then performed

co-culture

in vitro

cytotoxicity assays. Both of our versions of OR GATE

CAR-NK

cells, bivalent and bicistronic, showed significant cytotoxicity against the primary AML cells (p < 0.01) in comparison to unengineered NK controls.

Furthermore, we evaluated the OR GATE

CAR-NK

cells

in vivo

in two AML xenotransplantation tumor models using

MV4-11

and

MOLM-13

AML cell lines. As shown in the figures below, in each of the mouse models, our FLT3 OR CD33

CAR-NK

cells achieved statistically significantly greater anti-tumor activity compared to untreated control mice and mice treated with unengineered NK cells. Treatment with the OR GATE

CAR-NK

cells also improved survival compared to the control groups.

Table of Contents

As shown in the figure below, using the same proprietary transcriptomics and proteomics-based bioinformatics methodology discussed earlier, we identified EMCN as a target antigen that is highly expressed on healthy HSCs but not on AML LSCs or blasts. This validates EMCN’s potential as a Safety Antigen to protect HSCs from potential

on-target,

off-tumor

CAR-NK

mediated toxicity. The rationale for utilizing EMCN as the Safety Antigen is further bolstered by a previous finding in the literature that identified EMCN as a marker of the key cell type for repopulating the blood and immune systems.

Upon selection of EMCN as our primary Safety Antigen target, we have internally discovered and constructed multiple EMCN iCAR candidates, each comprised of an EMCN binder and a proprietary NOT GATE intracellular signaling domain. We then engineered NK cells with our lead FLT3 aCAR and these EMCN iCAR candidates to assess the EMCN iCARs’ ability to reduce

in vitro

cytotoxicity against a model healthy cell line that is engineered to be both FLT3+ and EMCN+. As shown in the figure below, we demonstrated, with multiple EMCN iCARs, that the NOT GATE conferred significant protection of EMCN-expressing cells from

CAR-NK-mediated

toxicity. The two different EMCN iCARs protected 50% to 67% of the EMCN+ cells from

CAR-NK

killing.

251

Table of Contents

We further evaluated the full

SENTI-202

gene circuit-equipped NK cells in a model of donor-derived primary HSCs. Unlike the model Healthy Cell line shown above, bone marrow-derived CD34 enriched primary HSCs have natural levels of both the Tumor-Associated Antigens, FLT3 and CD33, as well as EMCN, expressed on the cell surface and represent a more realistic model to evaluate our proprietary AML NOT GATE gene circuit. As shown below, while

SENTI-202

NK Cells, labeled as FLT3 OR CD33 NOT EMCN

CAR-NK

Cells, demonstrated killing of leukemia cell lines comparable to that of the control that does not express the EMCN iCAR, labeled as FLT3 OR CD33

CAR-NK

Cells, our NOT GATE enabled significant protection of primary HSCs, exceeding the 10% to 20% protection target we anticipate would provide clinical benefits to patients.

Development Plan and Key Next Steps for

SENTI-202

We have demonstrated, preclinically, the functionality of the key gene circuit components of

SENTI-202,

namely our FLT3 aCAR, CD33 aCAR and EMCN iCAR constructs. In 2022, we plan to present

IND-enabling

pharmacological data at key scientific conferences, seek feedback from the FDA through a

meeting, and apply for Orphan Drug Designation. In 2023, we plan to submit an IND application to support the clinical evaluation of

SENTI-202.

National Cancer Institute (NCI) Contract to Support Development of

SENTI-301

for the Potential Treatment of HCC

Overview

Our

SENTI-301

product candidate is a Multi-Armed allogeneic

CAR-NK

cell therapy that we are developing for the treatment of HCC. We are engineering NK cells to target GPC3, which is highly expressed in 70% to 90% of HCCs and has low or no expression on normal adult tissues.

SENTI-301

is armed with a combination of immuno-stimulatory payloads, including our proprietary

crIL-15

gene circuit, intended to promote expansion and persistence of our

CAR-NK

cells, as well as activation and recruitment of endogenous immune cells into the solid tumor microenvironment for enhanced anti-tumor activity. The expression of one of these potent payloads,

interleukin-12,

from

SENTI-301

may be modulated via a small molecule Regulator Dial or in response to CAR activity via a Smart Sensor such as a

CAR-activated

synthetic promoter.

In 2022, we plan to present

IND-enabling

pharmacological data at key scientific conferences, seek feedback from the FDA through a

pre-IND

meeting, and apply for Orphan Drug Designation. In 2023, we plan to submit an IND application to support the evaluation of

Hepatocellular Carcinoma: an Unmet Medical Need

HCC accounts for approximately 90% of primary liver cancers and represents a large unmet medical need due to the lack of effective treatment options. Globally, it is the sixth most commonly diagnosed cancer, and the fourth leading cause of cancer deaths. In the United States, the rate of death from liver cancer increased by 43% from 7.2 to 10.3 deaths per 100,000 people between 2000 and 2016. Frequently, HCC develops in patients with liver disease such as hepatitis C virus, alcoholic liver disease or

non-alcoholic

steatohepatitis.

Available therapies are only modestly efficacious and HCC mortality rate remains high despite recent improvements in treatment options. The most effective therapy currently available is atezolizumab plus bevacizumab combination therapy for first line treatment with a 27.3% objective response rate and a 5.5% complete response rate. Nivolumab plus ipilimumab combination therapy is the most effective second-line treatment currently available with a 15% to 16% objective response rate and a 1% to 2% complete response rate.

Table of Contents

SENTI-301

Approach to HCC

As shown in the figure below,

SENTI-301

allogeneic NK cells are engineered with multiple anti-tumor activities to achieve a Multi-Armed attack on solid tumors. Specifically,

SENTI-301

includes a CAR that targets GPC3 and secretion of

(i) crIL-15

for autocrine signaling to potentially promote

CAR-NK

cell proliferation, persistence, effector functions and paracrine signaling of surrounding immune cells and

(ii) IL-12

to activate and recruit endogenous immune cells in the tumor microenvironment in order to induce a potent immune response.

GPC3 is a Tumor-Associated Antigen expressed in approximately 70% to 90% of human HCCs, but not expressed in healthy liver tissue or other human organs after birth. GPC3 has previously been clinically evaluated as a therapeutic target for immunotherapy in HCC. GPC3 is also a histologic and serum clinical marker for HCC and its expression has been associated with poor prognosis. Functionally, GPC3 is associated with the control of cell division and growth regulation. We built GPC3 CAR constructs to redirect

NK-mediated

cytotoxicity against HCC using a GPC3 binder that associates to the membrane proximal region of the GPC3 protein.

As recombinant proteins, the

IL-15

and

IL-12

pleiotropic cytokines have previously demonstrated anti-tumor efficacy in several preclinical studies.

IL-15

has been shown to improve NK cell persistence

in vivo

and maintain cytotoxicity. Functionally,

IL-12

promotes the secretion of Th1 cytokines from other immune cells, potentiating the recruitment and activation of the endogenous innate and adaptive immune systems, which leads to subsequent induction of an anti-tumor immune response.

Our

crIL-15

gene circuit is designed to simultaneously produce both membrane-associated and fully secreted

IL-15

to support both autocrine- and paracrine-like signaling. As described above, our

crIL-15

gene circuit functionally improved

CAR-NK

effector functions in serial killing assays

in vitro

when compared to wild-type fully secreted

IL-15

alone. We believe that the ability of

crIL-15

to also secrete active

IL-15

into the tumor microenvironment should enable stimulation of endogenous immune cells within the tumor microenvironment in solid tumor settings.

Previous clinical experiences with adoptive cell transfer of engineered immune cells expressing

IL-12

have demonstrated the feasibility of

IL-12-secreting

cell therapies. However, systemic immunotoxicity has been observed in patients when

IL-12

is expressed without tight regulation from adoptive cell therapies. Thus, the narrow therapeutic window associated with

IL-12

has limited its success to date.

We believe our gene circuit technologies may address these previously observed therapeutic window limitations from clinical studies. One potential approach is to modulate the expression of

IL-12

using our Regulator Dial gene circuit. For example, a

NS3-based

Regulator Dial can be utilized to modulate

IL-12

expression

in vivo

after infusion of the

SENTI-301

product candidate via

FDA-approved,

orally dosed NS3 inhibitors. The NS3 Regulator Dial consists of a synthetic drug-regulated transcription factor and a synthetic

254

Table of Contents

promoter responsive to this regulated transcription factor. In the absence of the drug, the transcription factor is inactive, and no therapeutic protein (such as

IL-12)

is produced from the engineered cells. In the presence of the drug, the transcription factor is activated, leading to production of the

IL-12

payload.

A potential clinical application of the

NS3-based

Regulator Dial is illustrated in the figure below. Upon infusion of

SENTI-301,

the

IL-12

regulated gene circuit remains in the off state, thus limiting the potential of systemic immunotoxicity in patients. As infused

CAR-NK

cells survey the body, we expect local enrichment, activation and expansion of

SENTI-301

in GPC3-positive tumors. The antigen-driven anti-tumor response is further supported by the expression of

crIL-15.

Once local infiltration and engraftment of

SENTI-301

is established, NS3 inhibitors may be given to patients in order to induce

IL-12

expression and promote recruitment of endogenous immune cells to help further mount an anti-tumor response. By incorporating multiple therapeutic mechanisms, such as GPC3 CAR,

crIL-15

and regulated

IL-12,

into the allogeneic NK cells, we believe our

SENTI-301

product candidate would be armed with the necessary tools to activate multiple pathways in the tumor-immunity cycle in complementary ways in order to combat HCC and its hostile tumor microenvironment.

GPC3 CAR Expression and Function

We have designed and built hundreds of GPC3 CAR constructs, with the aim to identify and select our lead GPC3 CAR construct based on its expression profile and cytotoxic functions. These GPC3 CAR constructs were delivered into NK cells and evaluated. Anti-tumor cytotoxic functions were evaluated in

co-culture

assays against the HCC cell lines, HepG2 and HuH7. The figure below shows a representative experiment demonstrating that NK cells engineered to express a GPC3 CAR and

crIL-15,

shown below in teal, have significantly higher killing activity against HCC target cells (GPC3-positive) compared to unengineered NK cells in an Incucyte assay.

We have constructed and evaluated multiple

gene circuits. The figure below shows a representative experiment demonstrating robust simultaneous expression of both membrane-associated

from engineered NK cells.

Regulated

IL-12

expression

The gene circuit embedded in the

SENTI-301

product candidate is designed to enable regulated

IL-12

production. For example, we are optimizing the Regulator Dial gene circuit in immune cells to minimize basal expression, resulting in minimal production of

IL-12

in the absence of NS3 inhibitors, while maintaining high induced expression in a drug-dose dependent manner. As shown in the figure below, NK cells engineered with the

IL-12

regulated gene circuit were evaluated for induction of

IL-12

expression in the presence of the small molecule NS3 inhibitor, grazoprevir, or GRZ, over a range of small molecule concentrations. The basal

IL-12

expression was low at ~3 pg/mL. Peak induction was achieved at ~0.1 µM of GRZ, where production of

IL-12

was increased by greater than

100-fold

relative to the basal level. Importantly,

IL-12

production was observed at concentrations as low as 0.01 µM of GRZ, well below the known drug Cmax in humans of 0.23 µM.

256

This Regulator Dial gene circuit for

IL-12

was evaluated

in vivo

. As shown in the figure below, immune-deficient NSG mice were dosed with 37.5 mg/kg of GRZ on day 0 and subsequently 75 mg/kg GRZ from day 1 through day 4. These mice received 20×10

engineered cells on day 2. Blood samples were drawn on day 4 and day 8 to assess

IL-12

levels during the small molecule-induced state and post-small molecule withdrawal, respectively. We found that on day 4,

IL-12

was detected at 1,642 pg/mL in the plasma of mice that received GRZ versus 19 pg/mL in vehicle-treated mice (p < 0.01), a greater than

80-fold

upregulation of

IL-12

production. On day 8, 4 days after the final GRZ dose, both the

GRZ-

and vehicle-treated mice exhibited only background levels (20 – 30 pg/mL) of

IL-12,

demonstrating that

IL-12

production was switched off in the absence of GRZ.

SENTI-401

for the Potential Treatment of CRC

Overview

Our

SENTI-401

product candidate is a Logic Gated allogeneic

CAR-NK

cell therapy that we are developing to more precisely target and eliminate CRC cells while sparing healthy cells elsewhere in the body. We are engineering NK cells to express a CAR directed against CEA, which is highly overexpressed in 85% to 90% of colorectal cancer samples but is also expressed in epithelial cells in healthy tissues. The expression profile of CEA in both tumor and healthy cells has resulted in

on-target,

off-tumor

toxicities by conventional

CEA-targeted

therapies, thus limiting their clinical success. To address this challenge, we are engineering NK cells with a NOT GATE implemented via an iCAR targeted against an epithelial cell Safety Antigen called VSIG2. Thus, the

SENTI-401

product candidate’s logic gating is intended to more effectively treat CRC patients by targeting a well-known Tumor-Associated Antigen, CEA, and widen the therapeutic window by preventing killing when CEA appears on healthy cells that also express the VSIG2 Safety Antigen. Further,

SENTI-401

is being engineered to express our proprietary

crIL-15

effector to promote persistence and more durable antitumor functions.

In 2023, we plan to present

Colorectal Cancer: an Unmet Medical Need

CRC accounts for approximately 10% of all annually diagnosed cancers and cancer-related deaths worldwide and is the second and third most commonly diagnosed cancer in women and men, respectively. The incidence of CRC worldwide is predicted to increase to 2.5 million new cases in 2035. Of new colorectal cancer diagnoses, 20% of patients present with metastatic disease and another 25% who present with localized disease will later develop metastases. Among patients with metastatic colorectal cancer, approximately 70% to 75% of patients survive after one year of their initial diagnosis; however, the five-year survival rate is less than 20% despite multiple lines of treatment, including combinations of chemotherapy and targeted therapies.

258

Table of Contents

SENTI-401

Approach to CRC

CEA is a tumor-associated protein overexpressed in many epithelial cancers, most notably in colorectal cancer. However, it is also expressed in a variety of normal epithelial cells throughout the gastrointestinal tract. As shown in the figure below, bioinformatics analyses of RNA sequencing data collected from over 9,500 tumor and 8,500 healthy tissue samples showed that CEACAM5, one of the main isoforms of CEA, is overexpressed across many cancer types, especially colorectal cancer. CEACAM5 expression is also found in healthy organs, including tissues in the GI tract and lungs. Cancer immunotherapies using vaccines and antibodies targeting CEA are actively being investigated in the clinical setting. However, recent clinical studies have shown dose-limiting

on-target,

off-tumor

toxicities in these healthy tissues that also express CEA.

We are developing our

SENTI-401

product candidate to overcome the challenges associated with targeting the CEA Tumor-Associated Antigen that is present on both tumor and healthy cells. To mitigate the potential risk of

on-target,

off-tumor

toxicity, we are designing

SENTI-401

with a NOT GATE gene circuit to differentiate between cancerous and healthy cells. Specifically,

SENTI-401

incorporates the following gene circuit:

An iCAR with a NOT GATE gene circuit that restricts

CAR-mediated

cell killing to CRC cells that express CEA but not healthy cells that express an epithelial cell Safety Antigen, VSIG2. This NOT gate is designed to potentially reduce

on-target,

off-tumor

toxicity, thus potentially enabling more effective treatment of

CEA-expressing

cancers.

Our CEA aCAR-NK cells kill CRC cells in an antigen-dependent manner

We have designed, built and evaluated hundreds of CEA aCAR constructs by varying the antigen binders,

co-stimulatory

domains, and other parameters. We screened these CEA aCAR constructs for robust and durable expression on NK cells, and cytotoxicity against

CEA-positive

tumor cell lines. As shown in the figure below,

259

Table of Contents

we evaluated our CEA aCAR-transduced NK cells, labeled as CEA aCAR #1 and CEA aCAR #2, for anti-tumor cytotoxic functions against a

CEA-positive

CRC tumor cell line, Ls174t. Both of these CEA aCAR constructs, in comparison to unengineered NK cells or NK cells engineered with a

non-specific

aCAR construct, mediated statistically significant cytotoxicity against Ls174t and released cytokines in an antigen-specific manner.

Our CEA aCAR-NK cells significantly reduced tumor burden in a human CRC xenograft tumor model in vivo

To assess the

in vivo

activity of our

CAR-NK

cells, we developed human xenograft mouse models of

CEA-positive

CRC tumors. We implanted Ls174t CRC cells in the peritoneal cavity of NSG mice and measured tumor burden and disease progression using a bioluminescent reporter. Mice were treated with PBS, or with one single dose of unengineered NK cells or CEA aCAR-NK cells. CEA aCAR-NK cells resulted in significant reduction (p < 0.05) in tumor burden in mice compared to control mice treated with unengineered NK cells, as shown in the figure below.

Utilization of the VISG2 protein as our NOT GATE gene circuit Safety Antigen

We have developed a robust Tumor-Associated Antigen and Safety Antigen Paired Discovery Platform for the development of NOT GATE

CAR-NK

therapies. Using this approach, we have identified genes that are differentially expressed in healthy versus tumor tissues and selected antigen candidates based

on-target

expression in tissues, subcellular localization, antigen topology or presence of extracellular domains and antibody availability. To protect healthy epithelial cells that also express CEA, we discovered VSIG2 as a Safety Antigen candidate. VSIG2 exhibits a favorable pattern of expression in the membrane of epithelial cells of the gastrointestinal tract and lungs, which are

CEA-positive

tissues that are most at risk of

on-target,

off-tumor

toxicity. We further validated the expression of VSIG2 using immunohistochemistry, or IHC, in healthy tissues and confirmed the lack of expression in primary CRC tumor tissue samples. Specifically, IHC analyses of colorectal tumor tissues and healthy colon epithelium demonstrated that CEA is expressed in both healthy samples, as shown in the upper left of the figure below, and tumor samples, as shown in the lower left of the figure below. In addition, the Safety Antigen VSIG2 is only expressed in healthy colon epithelium, as shown in the upper right of the figure below, and not in tumor samples, as shown in the lower right of the figure below.

Leveraging these findings, we have constructed VISG2-iCARs that showed selective NOT gate functions

in vitro

. As shown in the figure below, we engineered NK cells to express both our CEA-aCAR and two different VSIG2-iCARs, each with a different intracellular inhibitory domain, at greater than 70% efficiency. These NOT gated CAR NK cells showed equivalent tumor killing relative to CEA aCAR only control NK cells, but were

261

Table of Contents

observed to significantly reduce cytotoxicity against a Model Healthy cell line, labelled CEACAM5+VSIG2+ below, by up to 43%.

Development Plan and Key Next Steps for

SENTI-401

In 2022, we intend to further evaluate different variants of the CEA aCAR and VSIG2 iCAR constructs, for example different aCAR

co-stimulatory

domains and iCAR inhibitory domains etc.,

in vitro

and

in vivo

to determine the exact final coding sequences of these individual components. These finalized key gene circuit components would then be incorporated into an optimized vector backbone for cGMP manufacturing. Concurrent with anticipated cGMP manufacturing activities in 2022 and 2023, we anticipate that

IND-enabling

pharmacology and toxicology studies will be executed to support future submission of an IND application.

Our Gene Circuit Application to Allogeneic, NK Cells for Oncology

CAR-NK

cells. We have chosen to engineer NK cells with our gene circuits based on our belief that NK cells confer the following advantages in relation to other potential immune cell types in oncology:

•

Innate Killing

: NK cells naturally carry multiple activating and inhibitory receptors that enable them to innately kill tumor cells while sparing healthy tissues. Furthermore, NK cells have been engineered with CARs to enhance their targeted killing activity. We leverage these features to create Logic Gated

CAR-NKs,

such as OR GATE

CAR-NKs

that enhance the killing of heterogeneous tumors and NOT GATE

CAR-NKs

that spare healthy cells from undesired toxicity and thereby potentially improve

on-target,

on-tumor

killing.

•

Immune Activation

: NK cells have been shown to support robust activation of anti-tumor immune pathways via proinflammatory cytokine and chemokine secretion. We leverage this feature with our Multi- Arming gene circuits to further improve their ability to trigger endogenous, complementary anti-tumor activity by engaging the rest of the tumor immunity cycle.

262

Table of Contents

•

Validated Clinical Activity and Tolerability

: Allogeneic, as in healthy donor-derived,

CAR-NK

cells have been recently shown in the clinical setting to have the potential to promote anti-tumor activity along with low risks of graft versus host disease, or GvHD, severe cytokine release syndrome, or CRS, and neurotoxicity.

•

Broad Patient Access

: We have established proprietary protocols to derive NK cells from healthy donors, manufacture them at scale with a projected low cost and cryopreserve them with high retained viability post-thaw. As a result, we believe that

CAR-NK

cells have the potential to be broadly accessible to patients as they may be delivered rapidly to patients in an

off-the-shelf

manner and in outpatient settings.

Portfolio Expansion Opportunities

Our Discovery Stage Programs

We believe our gene circuits can be readily adapted to new disease contexts to enable a variety of additional

CAR-NK

product candidates that address important cancers. As shown in the figure below, our

SENTI-421

product candidates are Logic Gated

CAR-NKs

that leverage the same NOT GATE gene circuit technology deployed in

We are developing these product candidates for precise targeting of solid tumors expressing certain Tumor-Associated Antigens, while protecting against

on-target,

off-tumor

CAR-NK

that utilizes our Multi-Arming gene circuit technology currently deployed in our

In particular, we have entered into collaborations with Spark Therapeutics, Inc. (acquired by Roche Holding AG) for the design of Smart Sensors for disease- and tissue-specific gene therapy, and with Bluerock Therapeutics, Inc. (acquired by Bayer AG) for the use of Smart Sensors and Regulator Dials for regenerative medicines.

Our current discovery stage programs are as follows:

We believe our gene circuit platform technologies can be broadly leveraged to address additional clinical indications. For example, there are additional opportunities for the application of the NOT GATE gene circuit toward other solid and/or liquid tumor indications beyond

SENTI-401,

SENTI-411

and

SENTI-421.

Toward that end, we have developed a Tumor-Associated Antigen and Safety Antigen Paired Discovery Platform to identify future opportunities.

264

Table of Contents

Tumor-Associated Antigen and Safety Antigen Paired Discovery Platform

We have developed a proprietary Tumor-Associated Antigen and Safety Antigen Paired Discovery Platform to select and validate NOT GATE antigen candidates, as shown in the figure below. We have built a generalizable bioinformatics pipeline that uses RNA transcriptomics data to discover and prioritize tumor and healthy tissue Safety Antigens. We identify Tumor-Associated Antigens that are highly expressed in cancer cells with as little healthy tissue expression as possible, for example Tumor-Associated Antigen A in the figure below. We then discover healthy tissue selective Safety Antigens, for example Safety Antigen E in the figure below, that can protect those healthy tissues that express the Tumor-Associated Antigens, for example Tissues 2 and 5 in the figure below. This process looks at differences in Safety Antigen gene expression in healthy versus tumor tissue. Leads are selected based on the

co-expression

of Tumor-Associated Antigens and Safety Antigens in healthy tissues, the localization of the Safety Antigens to the cell surface, Safety Antigen topology (presence of extracellular domain) and Safety Antigen-specific antibody availability. Prioritized Tumor-Associated Antigen and Safety Antigen pairs are further validated in primary cancer and primary healthy tissue samples. We leveraged this platform to identify the Safety Antigen targets for the

SENTI-202

and

SENTI-401

programs, thus demonstrating our ability to target both liquid and solid tumors. This approach allows us to potentially expand our NOT GATE approach to additional cancer indications in which existing single-target approaches, such as monoclonal antibodies, antibody-drug conjugates and single-target CAR cells, are inadequate due to a lack of specificity for cancer cells.

Portfolio Expansion Opportunities Outside of Oncology

Our additional discovery efforts are focused on cell and gene therapy applications that utilize other facets of our synthetic biology platform, including Smart Sensors and Regulator Dials in therapeutic areas beyond oncology.

Manufacturing

Internal manufacturing capabilities are central to our business strategy, since they can enable us to control the quality and supply of our allogeneic

CAR-NK

cell therapies for clinical studies and ultimately commercialization. A key advantage of allogeneic cell therapies, versus autologous products that use each

265

Table of Contents

patient’s own cells, is the ability to manufacture large batches of drug product from healthy donor cells that can be produced in advance of clinical use, and then stored in frozen vials. Upon commercialization, we expect to be able to make our cell therapies, if approved, broadly accessible in an

off-the-shelf

manner to cancer patients.

Our experienced manufacturing and process development team has established an innovative process for efficient production of our allogeneic

CAR-NK

cell product candidates. Critical aspects of the cell manufacturing process include the ability to perform four key steps in the

CAR-NK

cell manufacturing process:

Step 1: Source, Isolate and Bank Purified NK Cells as Starting Cells

Starting Cells are obtained from enriching and isolating NK cells from qualified healthy donors. Purified NK cells are subsequently cryopreserved and characterized for consistent performance, including assays for cell phenotype, transduction efficiency, cell expansion capability and anti-tumor cytotoxicity. For our initial

SENTI-301

product candidates, we plan to derive Starting Cells from leukapheresis products collected from qualified healthy donors. From each leukapheresis collection, we will isolate and cryopreserve hundreds of millions of Starting Cells to support multiple product production batches. We believe that peripheral blood derived leukapheresis products are an attractive starting material source due to (i) a mature and validated commercial supply chain, (ii) the large number of purified NK cells per collection and (iii) our ability to characterize the NK cells prior to initiation of manufacturing. An analysis of over a dozen recent isolations performed from different healthy donors demonstrated that our process achieved greater than 95% NK cell purity, greater than 90% viability and up to 500 million NK cells per collection, as shown in the figure below:

Step 2: Genetically Engineer Starting Cells with Gene Circuits

We genetically modify our NK cells through a viral vector transduction process focused on enhancing gene circuit expression while minimizing impacts on compromising cell viability or cell expansion. To generate our

CAR-NK

products, the Starting Cells are first thawed and activated. On a specific day post activation, the activated cells undergo our vector transduction process to genetically incorporate our gene circuits. The figure below shows transduction of our activated Starting Cells successfully reached approximately 50% transduction efficiency using a potentially clinically appropriate manufacturing process. Gene circuit-enabled

CAR-NK

cells were expanded over a total of 21 days. As shown in the center panel of the figure below, our transduction process was shown to have minimal impact on the cell expansion capability when comparing transduced

CAR-NK

cells versus unengineered NK cells. The transduced cells retained >90% viability with similar growth rate to unengineered NK cells through the 21st day.

Step 3: Expand and Scale

CAR-NK

Cells

Our expansion process is designed to generate large numbers of final product doses per manufacturing batch. This production process has resulted in high purity of NK cells (>98%) with minimal (<1%) detectable residual T cells. As shown in the figure below, our current process has produced greater than

6,000-fold

expansion of

CAR-NK

cells in a 21 day process, achieving a planned clinical manufacturing scale of hundreds of patient doses per a single manufacturing batch. We are developing additional technologies and processes to further enhance NK cell expansion for commercial manufacturing, including alternative methods for cell activation and expansion and utilization of large-scale cell culture systems.

Step 4: Formulate and Cryopreserve

CAR-NK

Cells

For freezing and distribution, we intend to formulate and cryopreserve our final product to retain viability, persistence and cytotoxic function post-thaw for

off-the-shelf

use. Each batch of

CAR-NK

cells will be filled into

267

Table of Contents

vials and cryopreserved for long term storage. The

CAR-NK

cell product candidates will be shipped in vials to clinical sites, where they will be thawed and infused on demand. We have demonstrated that cryopreserved

CAR-NK

cells can retain key functional properties required for cancer treatment, including stable transgene expression >44 days. As shown below, our cryopreserved

CAR-NK

cells retained viability and anti-tumor functions in both

in vitro

and

in vivo

models of AML:

Technical Expertise and Facilities for Clinical and Commercial Manufacturing

Our corporate headquarters is located in South San Francisco, CA, where we lease approximately 40,000 square feet of research and development and corporate office space. In this location, we have approximately 10,000 square feet dedicated to manufacturing development labs. We have established research and development teams with extensive experience in cell and gene therapy manufacturing operations, including vector process development, cell process development, analytical development, quality control and quality assurance. In June 2021, we signed a lease agreement for a property in Alameda, California with approximately 92,000 square feet and have begun construction on a

state-of-the-art

cGMP facility to support clinical and commercial-scale manufacturing of multiple allogeneic

CAR-NK

cell product candidates. This manufacturing facility is being designed as a customized

end-to-end

We expect to complete the first stage of construction for our cGMP facility and present on our clinical-scale GMP manufacturing process for gene-circuit-engineered NK cells at key technical conferences in 2022.

Our allogeneic production process and proprietary manufacturing capabilities are central to our business strategy of maintaining control over the quality and supply of our present and future candidates for allogeneic

CAR-NK

cell therapies. In addition, we believe that our proprietary manufacturing process enables an anticipated cost in line with competitive allogeneic production process estimates. Continued advancements in cell culture scale and process efficiencies may further reduce this cost over time.

In addition, we may also leverage our manufacturing facility to expand the application of our gene circuit technology to biomanufacturing in partnership with one or more third parties. See the section titled “Potential Collaboration Around Gene Circuits and GMP Manufacturing.”

Research Collaboration and License Agreement with Spark Therapeutics, Inc.

In April 2021, we entered into a Research Collaboration and License Agreement, or the Spark Agreement, with Spark Therapeutics, Inc., or Spark. Under the Spark Agreement, we engaged in a collaborative research program with Spark to design, build and test synthetic promoters that are intended to have each one of five sets of desired characteristics, or promoter profiles. Spark is obligated to reimburse us for our costs and expenses incurred in connection with the conduct of the research program. Upon completion of work under the research program for a particular promoter profile, Spark may select up to a specified number of synthetic promoters for such promoter profile on which it can conduct

in vitro

and

in vivo

evaluation activities.

We granted option rights to Spark, on a promoter

profile-by-promoter

profile basis, to obtain an exclusive, royalty-bearing, sublicensable, worldwide license under our intellectual property rights to develop, manufacture, commercialize and otherwise exploit, for the cure, treatment, palliation, prevention or diagnosis of specified indications, or a licensed field,

in vivo

gene therapy products incorporating an applicable synthetic promoter that is developed under the Spark Agreement with respect to such promoter profile and is directed towards specified cell types in the central nervous system, eye, or liver. Spark may exercise its option for a single synthetic promoter per promoter profile together with certain related synthetic promoters, or licensed promoters, prior to the expiration of the applicable evaluation period. During the research program and until the expiration of the evaluation period for each promoter profile, we are obligated to work exclusively with Spark on the development, manufacture and commercialization of

in vivo

gene therapy products incorporating synthetic promoters intended to have the same cell type specificity as such promoter profile.

After exercise of an option, Spark will be responsible for all development, manufacture, commercialization and exploitation in the licensed field, at its own cost and expense, of all

in vivo

gene therapy products containing an applicable licensed promoter, and we will retain the right to develop, manufacture, commercialize and exploit other products that incorporate the licensed promoters as well as

in vivo

gene therapy products that incorporate the licensed promoters for uses outside the licensed field. If Spark does not exercise an option for a particular promoter profile prior to the expiration of the evaluation period for such promoter profile, we will retain all rights to the synthetic promoters developed under the Spark Agreement without any further obligations to Spark for such promoter profile.

Pursuant to the Spark Agreement, we received an upfront payment from Spark of $3 million. If Spark exercises an option for a particular promoter profile, it will be required to pay us an option exercise fee in the low to mid- single digit millions. For each licensed promoter-containing

in vivo

gene therapy product, or licensed product, developed and commercialized by Spark or its affiliates or sublicensees, we are eligible to receive development, regulatory and commercialization milestone payments from Spark up to an aggregate dollar amount in the mid teens millions, and sales milestone payments from Spark up to an aggregate dollar amount in the low hundred millions. In total, we are potentially eligible to receive upfront,

opt-in

and milestone payments exceeding $645 million if Spark exercises its options for all five promoter profiles and Spark, its affiliates and its sublicensees successfully develop and commercialize five licensed products; we will be eligible to receive additional milestone payments if additional licensed products are developed and commercialized by Spark, its affiliates and its sublicensees. Further, Spark will be obligated to pay us royalties in the

low-single

digits percentage on net sales of each licensed product sold by Spark, its affiliates and its sublicensees, subject to specified reductions and offsets. Spark’s obligation to pay royalties to us will expire for each licensed product when certain licensed patents and regulatory exclusivities have expired in the country of sale and a minimum number of years has elapsed since the first commercial sale of such licensed product in such country.

272

Table of Contents

The Spark Agreement will expire at the end of the last evaluation period if Spark does not exercise any of its options. If Spark exercises at least one option, then the Spark Agreement will expire, on a licensed

product-by-licensed

product and

country-by-country

basis, upon the expiration of Spark’s royalty obligation for such licensed product in such country. Spark may terminate the Spark Agreement in its entirety, or on a promoter

profile or licensed

promoter-by-licensed

promoter basis, following a specified notice period. Either party may terminate the Spark Agreement in its entirety or in part if the other party fails to cure its material breach of the Spark Agreement within a specified cure period, or immediately if the other party becomes bankrupt or insolvent. We may terminate the Spark Agreement if Spark or any of its affiliates commences any action challenging the validity or enforceability of the licensed patents, other than in certain specified circumstances, or if Spark’s sublicensee challenges our licensed patents, under certain specified circumstances.

Collaboration and Option Agreement with BlueRock Therapeutics LP

In May 2021, we entered into a Collaboration and Option Agreement, or the BlueRock Agreement, with BlueRock Therapeutics LP, or BlueRock. BlueRock is a wholly-owned subsidiary of Bayer Healthcare LLC. Bayer Healthcare LLC’s parent company is Bayer AG, which served as the lead investor in our Series B financing through its Leaps by Bayer unit. Under the BlueRock Agreement, we have engaged in three collaboration programs with BlueRock to research and develop gene circuits that have specified functions. We are responsible for up to $10 million in costs and expenses incurred in connection with our conduct of research activities under an agreed-upon research plan. If the parties mutually agree to add new research activities to the research plan, then BlueRock will be obligated to reimburse us for the costs and expenses that we incur in connection with the agreed-upon additional research activities that, together with costs and expenses incurred under the initial research plan, exceed $10 million. We have not yet received any payment from BlueRock under the BlueRock Agreement and we do not have any obligations to make any payments to BlueRock under the BlueRock Agreement. We are obligated to use commercially reasonable efforts to conduct the research activities assigned to us under the research plan. If we materially breach that obligation and do not cure it within a specified period, BlueRock will have the right to receive a transfer of technology and perform the remainder of the research plan at its own expense.

Upon completion of work under a research plan for a collaboration program, the joint steering committee established by the parties will identify, subject to a specified maximum, a number of gene circuits per collaboration program, or option gene circuits, that have been successfully developed under such collaboration program. We have granted to BlueRock an option, on a collaboration

program-by-collaboration

program basis, to obtain an exclusive or

non-exclusive

license under our intellectual property rights to develop, manufacture and commercialize, for the prevention, treatment or palliation of specified indications, or a licensed field, cell therapy products that contain cells of specified types that incorporate an option gene circuit from such collaboration program or a closely related derivative gene circuit. For each collaboration program, BlueRock may conduct evaluation activities on the option gene circuits from such collaboration program to determine whether to exercise its option, and BlueRock may exercise its option to such option gene circuits together with certain closely related derivative gene circuits, or licensed gene circuits, prior to the expiration of a certain time period, or the option exercise period, which includes a minimum amount of time after the expiration of the three-year research term, delivery of a data package to BlueRock, and completion of a transfer of technology to enable BlueRock’s evaluation activities, whichever happens last. If BlueRock exercises its option for a collaboration program, the parties shall negotiate the financial terms, which will be within certain

pre-agreed

parameters and may be determined by baseball arbitration if the parties do not reach agreement within the specified negotiation period, and enter into an otherwise agreed-upon written license agreement, or a commercial license. If the parties enter into a commercial license, BlueRock will be responsible, at its sole expense, for the development, manufacture and commercialization, in the applicable licensed field, of cell therapy products containing cells of an applicable type that incorporate an applicable licensed gene circuit, and we will be eligible to receive from BlueRock development, regulatory and commercialization milestone payments, in amounts to be agreed-upon before entry into the commercial license, and royalties, subject to negotiation, equal to low single digit percentages of net sales of applicable cell therapy products sold by BlueRock, its affiliates and its sublicensees,

273

Table of Contents

subject to specified reductions and offsets. If BlueRock does not exercise its option for a collaboration program prior to the expiration of the applicable option exercise period, then we will retain all rights to the gene circuits developed under such collaboration program without any further obligations to BlueRock.

For each collaboration program, we are obligated to work exclusively with BlueRock on the development, manufacture and commercialization, in the applicable licensed field, of cell therapy products that contain cells of specified types that incorporate the specific type of gene circuit for such collaboration program. The end date for this exclusivity obligation for each collaboration program will depend upon whether BlueRock exercises its option for such collaboration program and, if it does, whether the parties enter into a commercial license for such collaboration program. If BlueRock does not exercise its option, then it will end on the expiration of the applicable option exercise period. If BlueRock exercises its option but the parties do not enter into a commercial license, then it will end after a specified time following expiration of the applicable negotiation or baseball arbitration period for the commercial license. If BlueRock exercises its option and the parties enter into a commercial license, then it will end a certain amount of time after the later of completion of research activities or execution of the commercial license.

In addition to the option described above, we granted a right of first negotiation to BlueRock, on a collaboration

program-by-collaboration

program basis, to obtain a license under our intellectual property rights to research, develop, manufacture and commercialize, for the prevention, treatment or palliation of a specified disease area, or the negotiation field, cell therapy products containing cells of a specified type, or the negotiation cells, that incorporate an applicable efficacy gene circuit developed under such collaboration program. This right of first negotiation does not overlap with the option described above because it pertains to different combinations of indications, cell types and gene circuits. Starting from the effective date of the BlueRock Agreement and, on a collaboration

program-by-collaboration

program basis, continuing for twelve months or, if later, until the completion of a certain portion of the research plan for such collaboration program, we are obligated to work exclusively with BlueRock on the development, manufacture and commercialization, in the negotiation field, of cell therapy products containing negotiation cells that incorporate the specific type of gene circuit for such collaboration program.

The BlueRock Agreement will expire, on a collaboration

program-by-collaboration

program basis, upon the earliest of the expiration of the option exercise period for such collaboration program, the effective date of the commercial license, the expiration of the applicable negotiation or baseball arbitration period for the commercial license, or the date the parties mutually agree to cease negotiations for the commercial license. Such expiration shall occur no later than January 2026 unless the parties mutually agree to extend the research term. BlueRock may terminate the BlueRock Agreement in its entirety, or on a collaboration

program-by-collaboration

program basis, following a specified notice period. Either party may terminate the BlueRock Agreement if the other party fails to cure its material breach of the BlueRock Agreement within a specified cure period, or immediately if the other party becomes bankrupt or insolvent. We may terminate the BlueRock Agreement if BlueRock or any of its affiliates commences any action challenging the validity or enforceability of our patents, other than in certain specified circumstances, or if BlueRock’s sublicensee challenges our patents under certain specified circumstances.

program will be funded in part with Federal funds from the National Cancer Institute, National Institutes of Health, Department of Health and Human Services, under Contract No. 75N91021C00026.

Potential Collaboration Around Gene Circuits and GMP Manufacturing

We may seek to leverage our manufacturing capabilities and proposed cGMP facility to enable us to expand the application of our gene circuit technology through a partnership in the biomanufacturing space. While we intend to use our proprietary gene circuit technology and manufacturing facility primarily for therapeutic product development and commercialization, our technology and facility can also be applied to noncompetitive biomanufacturing applications, which we believe is an approach well-suited for partnering. A potential biomanufacturing partnership could involve retaining operational control and manufacturing supply of our therapeutic candidates, while our partner could control part of the facility for its own use. The following is an illustrative depiction of the framework for a potential biomanufacturing partnership:

We currently have no agreements or commitments for a manufacturing partnership, and we could determine to advance our manufacturing plans without a partner.

Competition

We are aware of other companies that are developing technologies that may compete with elements of our gene circuit platform technologies, including A2 Biotherapeutics, Inc., Arsenal Biosciences, Inc., Beam Therapeutics Inc., CRISPR Therapeutics AG, Encoded Therapeutics, Inc., ImmPACT Bio USA, Inc., Intellia Therapeutics, Inc., MeiraGTx Holdings plc, Obsidian Therapeutics, Inc. and Strand Therapeutics Inc. We are also aware of other companies that are focused on the application of engineered

CAR-based

immune cell therapies, including NK cells, to oncology, and such competitors include Allogene Therapeutics, Inc., Artiva Biotherapeutics, Inc., Atara Biotherapeutics, Inc., Bristol-Myers Squibb Company, Century Therapeutics, Inc., Caribou Biosciences, Inc., Catamaran Bio, Inc., Cytovia Therapeutics, Inc., Editas Medicine, Inc., Fate Therapeutics, Inc., Gilead Sciences, Inc., Lyell Immunopharma, Inc., Nkarta, Inc., Sana Biotechnology, Inc., Shoreline Biosciences, Inc., Takeda Pharmaceutical Company and Vor Biopharma Inc. Some of these companies may have substantially greater financial and other resources than we have, such as larger research and development staff and well-established marketing and salesforces. Mergers and acquisitions in the biotechnology industry may result in even greater resource concentration among a smaller number of competitors. Smaller or early-stage companies may also prove to be significant competitors, either alone or through collaborative arrangements with large and established companies.

These companies compete with us in recruiting scientific and managerial talent. Our success will partially depend on our ability to obtain, maintain, enforce and defend patents and other intellectual property rights with

275

Table of Contents

respect to our product candidates. Our competitors may obtain FDA or other regulatory approval for their product candidates more rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market position before we are able to enter the market.

Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than any products that we may develop.

Intellectual Property

Intellectual property is the foundation of our company and not only defines who we are, but is the lens through which we implement our business strategy and research and development. Our overall strategy is to own and control all intellectual property related to our gene circuits. We protect our proprietary technology and intellectual property rights through a combination of wholly-owned patent rights, licensed patent rights in particular fields of use, trademark rights, trade secrets and

know-how,

contractual provisions and confidentiality procedures. Our general strategy includes protecting our proprietary technology and intellectual property rights domestically and in certain key foreign markets. We continually grow and supplement our intellectual property portfolio with new filings and applications not only to strengthen the protection of proprietary technology and intellectual property rights, but also to protect and support the development and commercialization of current and future product candidates.

Government Regulation

The U.S. Food and Drug Administration, or FDA, and other regulatory authorities at federal, state and local levels, as well as in foreign countries, extensively regulate, among other things, the research, development, testing, manufacture, quality control, import, export, safety, effectiveness, labeling, packaging, storage, distribution, record keeping, approval, advertising, promotion, marketing, sampling post-approval monitoring and post-approval reporting of biologics such as those we are developing. Any product candidates that we develop must be approved by the FDA before they may be legally marketed in the United States and by the appropriate foreign regulatory agency before they may be legally marketed in those foreign countries. Generally, our activities in other countries will be subject to regulation that is similar in nature and scope as that imposed in the United States, although there can be important differences.

U.S. Biologics Regulation

In the United States, biological products are subject to regulation under the Federal Food, Drug, and Cosmetic Act, the Public Health Service Act, and other federal, state, local and foreign statutes and their implementing regulations. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial resources. The process required by the FDA before biologics may be marketed in the United States generally involves the following:

•

completion of preclinical laboratory tests and animal studies performed in accordance with the FDA’s Good Laboratory Practice requirements, or GLP;

•

submission to the FDA of an investigational new drug application, or IND, which must become effective before clinical trials may begin;

•

approval by an institutional review board, or IRB, or ethics committee at each clinical site before the trial is commenced;

•

performance of adequate and well-controlled human clinical trials according to the FDA’s regulations commonly referred to as good clinical practice, or GCP, regulations and any additional requirements for the protection of human research subjects and their health information to establish the safety, purity and potency of the proposed biologic product candidate for its intended purpose;

277

inspection of the manufacturing facility or facilities at which the proposed product is produced to assess compliance with cGMP, and to assure that the facilities, methods and controls are adequate to preserve the biological product’s continued safety, purity and potency and, if applicable, to assess compliance with the FDA’s current Good Tissue Practice, or cGTP, requirements for the use of human cellular and tissue products, and of selected clinical investigation sites to assess compliance with GCPs;

•

potential FDA audit of the nonclinical and clinical study sites that generated the data in support of the BLA; and

•

FDA review and approval of the BLA to permit commercial marketing of the product for particular indications for use in the United States.

Before testing any biological product candidate in humans, the product candidate enters the preclinical testing stage. Preclinical tests, also referred to as nonclinical studies, include laboratory evaluations of product chemistry, toxicity and formulation, as well as animal studies to assess the potential safety and activity of the product candidate. The conduct of the preclinical tests must comply with federal regulations and requirements including GLPs.

Prior to beginning the first clinical trial with a product candidate in the United States, we must submit an IND to the FDA. An IND is a request for authorization from the FDA to administer an investigational new drug to humans. The central focus of an IND submission is on the general investigational plan and the protocol(s) for clinical studies. Some preclinical testing may continue even after the IND is submitted. The IND also includes results of animal and

in vitro

studies assessing the toxicology, pharmacokinetics, pharmacology and pharmacodynamic characteristics of the product; chemistry, manufacturing and controls information; and any available human data or literature to support the use of the investigational product. An IND must become effective before human clinical trials may begin. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA, within the

30-day

time period, raises safety concerns or questions about the proposed clinical trial. In such a case, the IND may be placed on clinical hold and the IND sponsor and the FDA must resolve any outstanding concerns or questions before the clinical trial can begin. Submission of an IND therefore may or may not result in FDA authorization to begin a clinical trial.

Clinical trials involve the administration of the investigational product to human subjects under the supervision of qualified investigators in accordance with GCPs, which include the requirement that all research subjects provide their informed consent for their participation in any clinical study. Clinical trials are conducted

278

Table of Contents

under protocols detailing, among other things, the objectives of the study, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated. A separate submission to the existing IND must be made for each successive clinical trial conducted during product development and for any subsequent protocol amendments. Furthermore, an independent IRB for each site proposing to conduct the clinical trial must review and approve the plan for any clinical trial and its informed consent form before the clinical trial begins at that site, and must monitor the study until completed. An IRB is charged with protecting the welfare and rights of trial participants and considers such items as whether the risks to individuals participating in the clinical trials are minimized and are reasonable in relation to anticipated benefits. The IRB also approves the informed consent form that must be provided to each clinical trial subject or his or her legal representative and must monitor the clinical trial until completed. Regulatory authorities, the IRB or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the subjects are being exposed to an unacceptable health risk or that the trial is unlikely to meet its stated objectives. Some studies also include oversight by an independent group of qualified experts organized by the clinical study sponsor, known as a data safety monitoring board, which provides authorization for whether or not a study may move forward at designated check points based on access to certain data from the study and may halt the clinical trial if it determines that there is an unacceptable safety risk for subjects or other grounds, such as no demonstration of efficacy. There are also requirements governing the reporting of ongoing clinical studies and clinical study results to public registries.

For purposes of BLA approval, human clinical trials are typically conducted in three sequential phases that may overlap or be combined:

•

Phase 1—The investigational product is initially introduced into healthy human subjects or patients with the target disease or condition. These studies are designed to test the safety, dosage tolerance, absorption, metabolism and distribution of the investigational product in humans, the side effects associated with increasing doses, and, if possible, to gain early evidence on effectiveness. In the case of some products for severe or life-threatening diseases, such as cancer, especially when the product may be too inherently toxic to ethically administer to healthy volunteers, the initial human testing is often conducted in patients.

•

Phase 2—The investigational product is administered to a limited patient population with a specified disease or condition to evaluate the preliminary efficacy, optimal dosages, dose tolerance and dosing schedule and to identify possible adverse side effects and safety risks. Multiple Phase 2 clinical trials may be conducted to obtain information prior to beginning larger and more expensive Phase 3 clinical trials.

•

Phase 3—The investigational product is administered to an expanded patient population to further evaluate dosage, to provide statistically significant evidence of clinical efficacy and to further test for safety, generally at multiple geographically dispersed clinical trial sites. These clinical trials are intended to establish the overall risk/benefit ratio of the investigational product and to provide an adequate basis for product approval. Generally, two adequate and well-controlled Phase 3 clinical trials are required by the FDA for approval of a BLA.

In some cases, the FDA may require, or companies may voluntarily pursue, additional clinical trials after a product is approved to gain more information about the product in the intended therapeutic indication, particularly for long-term safety

follow-up.

Completion of these

so-called

Phase 4 studies may also be made a condition to approval of the BLA.

Concurrent with clinical trials, companies may complete additional animal studies and develop additional information about the biological characteristics of the product candidate, and must finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other things, must develop methods for testing the safety, purity and potency of the final product. Additionally, appropriate packaging must be selected and tested, and stability studies must be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life.

BLA Submission and Review by the FDA

Assuming successful completion of all required testing in accordance with all applicable regulatory requirements, the results of product development, nonclinical studies and clinical trials are submitted to the FDA as part of a BLA requesting approval to market the product for one or more indications. The BLA must include all relevant data available from preclinical and clinical studies, including negative or ambiguous results as well as positive findings, together with detailed information relating to the product’s chemistry, manufacturing, controls and proposed labeling, among other things. Data can come from company-sponsored clinical studies intended to test the safety and effectiveness of a use of the product, or from a number of alternative sources, including studies initiated by independent investigators. To support marketing approval, the data submitted must be sufficient in quality and quantity to establish the safety and effectiveness of the investigational drug product to the satisfaction of the FDA. The submission of a BLA requires payment of a substantial application user fee to the FDA, unless a waiver or exemption applies.

Within 60 days following submission of the application, the FDA reviews a BLA submitted to determine if it is substantially complete before the FDA accepts it for filing. The FDA may refuse to file any BLA that it deems incomplete or not properly reviewable at the time of submission and may request additional information. In this event, the BLA must be resubmitted with the additional information. The resubmitted application also is subject to review before the FDA accepts it for filing.

Once a BLA has been accepted for filing, the FDA’s goal is to review standard applications within ten months after the filing date, or, if the application qualifies for priority review, six months after the FDA accepts the application for filing. In both standard and priority reviews, the review process may also be extended by FDA requests for additional information or clarification. The FDA reviews a BLA to determine, among other things, whether a product is safe, pure and potent and the facility in which it is manufactured, processed, packed or held meets standards designed to assure the product’s continued safety, purity and potency. The FDA may also convene an advisory committee to provide clinical insight on application review questions. An advisory committee is a panel of independent experts, including clinicians and other scientific experts, that reviews, evaluates and provides a recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions.

Before approving a BLA, the FDA will typically inspect the facility or facilities where the product is manufactured. The FDA will not approve an application unless it determines that the manufacturing processes and facilities are in compliance with cGMP and adequate to assure consistent production of the product within required specifications. For a product candidate that is also a human cellular or tissue product, the FDA also will not approve the application if the manufacturer is not in compliance with cGTPs. These are FDA regulations that govern the methods used in, and the facilities and controls used for, the manufacture of human cells, tissues, and cellular and tissue based products, or HCT/Ps, which are human cells or tissue intended for implantation, transplant, infusion, or transfer into a human recipient. The primary intent of the GTP requirements is to ensure that cell and tissue based products are manufactured in a manner designed to prevent the introduction, transmission and spread of communicable disease. FDA regulations also require tissue establishments to register and list their HCT/Ps with the FDA and, when applicable, to evaluate donors through screening and testing. Additionally, before approving a BLA, the FDA will typically inspect one or more clinical sites to assure compliance with GCP. If the FDA determines that the application, manufacturing process or manufacturing facilities are not acceptable, it will outline the deficiencies in the submission and often will request additional testing or information. Notwithstanding the submission of any requested additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval.

After the FDA evaluates a BLA and conducts inspections of manufacturing facilities where the investigational product and/or its drug substance will be produced, the FDA may issue an approval letter or a Complete Response Letter, or CRL. An approval letter authorizes commercial marketing of the product with

280

Table of Contents

specific prescribing information for specific indications. A CRL indicates that the review cycle of the application is complete, and the application will not be approved in its present form. A CRL will describe all of the deficiencies that the FDA has identified in the BLA, except that where the FDA determines that the data supporting the application are inadequate to support approval, the FDA may issue the CRL without first conducting required inspections, testing submitted product lots, and/or reviewing proposed labeling. In issuing the CRL, the FDA may recommend actions that the applicant might take to place the BLA in condition for approval, including requests for additional information or clarification. The FDA may delay or refuse approval of a BLA if applicable regulatory criteria are not satisfied, require additional testing or information and/or require post-marketing testing and surveillance to monitor safety or efficacy of a product. If a CRL is issued, the sponsor must resubmit the BLA, addressing all of the deficiencies identified in the letter, or withdraw the application. Even if such data and information are submitted, the FDA may decide that the BLA does not satisfy the criteria for approval.

If regulatory approval of a product is granted, such approval will be granted for particular indications and may entail limitations on the indicated uses for which such product may be marketed. For example, the FDA may approve the BLA with a Risk Evaluation and Mitigation Strategy, or REMS, to ensure the benefits of the product outweigh its risks, or otherwise limit the scope of any approval. A REMS is a safety strategy implemented to manage a known or potential serious risk associated with a product and to enable patients to have continued access to such medicines by managing their safe use, and could include medication guides, physician communication plans or elements to assure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. The FDA also may condition approval on, among other things, changes to proposed labeling or the development of adequate controls and specifications. Once approved, the FDA may withdraw the product approval if compliance with

pre-

and post-marketing requirements is not maintained or if problems occur after the product reaches the marketplace. The FDA may require one or more Phase 4 post-market studies and surveillance to further assess and monitor the product’s safety and effectiveness after commercialization, and may limit further marketing of the product based on the results of these post-marketing studies.

Expedited Development and Review Programs

The FDA offers a number of expedited development and review programs for qualifying product candidates. For example, new biological products are eligible for fast track designation if they are intended to treat a serious or life-threatening disease or condition and demonstrate the potential to address unmet medical needs for the disease or condition. Fast track designation applies to the combination of the product and the specific indication for which it is being studied. The sponsor of a new biologic may request that the FDA designate the biologic as a fast track product at any time during the clinical development of the product. The sponsor of a fast track product has opportunities for more frequent interactions with the applicable FDA review team during product development and, once a BLA is submitted, the product candidate may be eligible for priority review. A fast track product may also be eligible for rolling review, where the FDA may consider for review sections of the BLA on a rolling basis before the complete application is submitted, if the sponsor provides a schedule for the submission of the sections of the BLA, the FDA agrees to accept sections of the BLA and determines that the schedule is acceptable, and the sponsor pays any required user fees upon submission of the first section of the BLA.

A product candidate intended to treat a serious or life-threatening disease or condition may also be eligible for breakthrough therapy designation to expedite its development and review. A product candidate can receive breakthrough therapy designation if preliminary clinical evidence indicates that the product candidate, alone or in combination with one or more other drugs or biologics, may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. The designation includes all of the fast track program features, as well as more intensive FDA interaction and guidance beginning as early as Phase 1 and an organizational commitment to expedite the development and review of the product candidate, including involvement of senior managers.

281

Table of Contents

Any marketing application for a biologic submitted to the FDA for approval, including a product candidate with a fast track designation and/or breakthrough therapy designation, may be eligible for other types of FDA programs intended to expedite development and review, such as priority review and accelerated approval. A product candidate is eligible for priority review if it has the potential to provide safe and effective therapy where no satisfactory alternative therapy exists or a significant improvement in the treatment, diagnosis or prevention of a disease compared to marketed products. The FDA will attempt to direct additional resources to the evaluation of an application for a new biological product designated for priority review in an effort to facilitate the review. For original BLAs, priority review designation means the FDA’s goal is to take action on the marketing application within six months of the

60-day

filing date (as compared to ten months under standard review).

Additionally, product candidates studied for their safety and effectiveness in treating serious or life-threatening diseases or conditions may receive accelerated approval upon a determination that the product has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity or prevalence of the condition and the availability or lack of alternative treatments. As a condition of accelerated approval, the FDA will generally require the sponsor to perform adequate and well-controlled post-marketing clinical studies to verify and describe the anticipated effect on irreversible morbidity or mortality or other clinical benefit. Products receiving accelerated approval may be subject to expedited withdrawal procedures if the sponsor fails to conduct the required post-marketing studies or if such studies fail to verify the predicted clinical benefit. In addition, for products being considered for accelerated approval, the FDA generally requires, unless otherwise informed by FDA, that all advertising and promotional materials intended for dissemination or publication within 120 days of marketing approval be submitted to FDA for review during the

pre-approval

period.

In 2017, the FDA established a new regenerative medicine advanced therapy, or RMAT, designation, which is intended to facilitate an efficient development program for, and expedite review of, any biologic that meets the following criteria: (i) the biologic qualifies as a RMAT, which is defined as a cell therapy, therapeutic tissue engineering product, human cell and tissue product, or any combination product using such therapies or products, with limited exceptions; (ii) the biologic is intended to treat, modify, reverse, or cure a serious or life-threatening disease or condition; and (iii) preliminary clinical evidence indicates that the biologic has the potential to address unmet medical needs for such a disease or condition. RMAT designation provides all the benefits of breakthrough therapy designation, including more frequent meetings with the FDA to discuss the development plan for the product candidate and eligibility for rolling review and priority review. Product candidates granted RMAT designation may also be eligible for accelerated approval on the basis of a surrogate or intermediate endpoint reasonably likely to predict long-term clinical benefit, or reliance upon data obtained from a meaningful number of clinical trial sites, including through expansion of trials to additional sites. RMAT-designated products that receive accelerated approval may, as appropriate, fulfill their post-approval requirements through submission of clinical evidence, clinical studies, patient registries, or other sources of real-world evidence (such as electronic health records); through the collection of larger confirmatory data sets; or via post-approval monitoring of all patients treated with such therapy prior to approval of such therapy.

Fast track designation, breakthrough therapy designation, priority review, accelerated approval, and RMAT designation do not change the standards for approval but may expedite the development or approval process. Even if a product candidate qualifies for one or more of these programs, the FDA may later decide that the product no longer meets the conditions for qualification or decide that the time period for FDA review or approval will not be shortened.

Orphan Drug Designation and Exclusivity

Under the Orphan Drug Act, the FDA may grant orphan designation to a biologic intended to treat a rare disease or condition, defined as a disease or condition with a patient population of fewer than 200,000 individuals in the United States, or a patient population greater than 200,000 individuals in the United States and when there

282

Table of Contents

is no reasonable expectation that the cost of developing and making available the drug or biologic in the United States will be recovered from sales in the United States for that biologic. Orphan drug designation must be requested before submitting a BLA. After the FDA grants orphan drug designation, the generic identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. Orphan drug designation does not convey any advantage in or shorten the duration of the regulatory review and approval process.

In the United States, orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages and

user-fee

waivers. In addition, if a product that has orphan drug designation subsequently receives the first FDA approval for a particular drug or biologic for the disease for which it has such designation, the product is entitled to orphan product exclusivity, which means that the FDA may not approve any other applications, including a full BLA, to market the same biologic for the same indication for seven years, except in limited circumstances, such as a showing of clinical superiority to the product with orphan drug exclusivity or if the FDA finds that the holder of the orphan drug exclusivity has not shown that it can assure the availability of sufficient quantities of the orphan drug to meet the needs of patients with the disease or condition for which the drug was designated. Orphan drug exclusivity does not prevent the FDA from approving a different drug or biologic for the same disease or condition, or the same drug or biologic for a different disease or condition. Competitors may receive approval of different products for the indication for which the orphan product has exclusivity or obtain approval for the same product but for a different indication for which the orphan product has exclusivity. Orphan product exclusivity also could block the approval of one of our products for seven years if a competitor obtains approval of the same biological product as defined by the FDA or if our product candidate is determined to be contained within the competitor’s product for the same indication or disease.

A designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which it received orphan designation. In addition, orphan drug exclusive marketing rights in the United States may be lost if the FDA later determines that the request for designation was materially defective or, as noted above, if a second applicant demonstrates that its product is clinically superior to the approved product with orphan exclusivity or the manufacturer of the approved product is unable to assure sufficient quantities of the product to meet the needs of patients with the rare disease or condition.

Post-Approval Requirements

Biologics are subject to pervasive and continuing regulation by the FDA, including, among other things, requirements relating to record-keeping, reporting of adverse experiences, periodic reporting, product sampling and distribution, and advertising and promotion of the product. After approval, most changes to the approved product, such as adding new indications or other labeling claims, are subject to prior FDA review and approval. There also are continuing, annual program fees for any marketed products. Biologic manufacturers and other entities involved in the manufacture and distribution of approved biological products are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP requirements and other laws, which impose certain procedural and documentation requirements upon us and our third-party manufacturers. Manufacturers and other parties involved in the drug supply chain for prescription drug products must also comply with product tracking and tracing requirements and for notifying the FDA of counterfeit, diverted, stolen and intentionally adulterated products or products that are otherwise unfit for distribution in the United States. Accordingly, manufacturers must continue to expend time, money, and effort in the area of production and quality control to maintain GMP compliance. Changes to the manufacturing process or facility are strictly regulated, and, depending on the significance of the change, may require prior FDA approval before being implemented. FDA regulations also require investigation and correction of any deviations from cGMP and impose reporting requirements upon us and any third-party manufacturers that we may decide to use. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain compliance with cGMP and other aspects of regulatory compliance.

The FDA may withdraw approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown

283

Table of Contents

problems with a product, including adverse events of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-market studies or clinical studies to assess new safety risks; or imposition of distribution restrictions or other restrictions under a REMS program. Other potential consequences include, among other things:

•

restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the market or product recalls;

•

fines, warning letters, or untitled letters;

•

clinical holds on clinical studies;

•

refusal of the FDA to approve pending applications or supplements to approved applications, or suspension or revocation of product license approvals;

•

product seizure or detention, or refusal to permit the import or export of products;

•

consent decrees, corporate integrity agreements, debarment or exclusion from federal healthcare programs;

•

mandated modification of promotional materials and labeling and the issuance of corrective information;

•

the issuance of safety alerts, Dear Healthcare Provider letters, press releases and other communications containing warnings or other safety information about the product; or

•

injunctions or the imposition of civil or criminal penalties.

The FDA also may require post-marketing testing, known as Phase 4 testing, and surveillance to monitor the effects of an approved product. Discovery of previously unknown problems with a product or the failure to comply with applicable FDA requirements can have negative consequences, including adverse publicity, judicial or administrative enforcement, warning letters from the FDA, mandated corrective advertising or communications with doctors, and civil or criminal penalties, among others. Newly discovered or developed safety or effectiveness data may require changes to a product’s approved labeling, including the addition of new warnings and contraindications, and also may require the implementation of other risk management measures.

The FDA closely regulates the marketing, labeling, advertising and promotion of biologics. A company can make only those claims relating to safety and efficacy, purity and potency that are approved by the FDA and in accordance with the provisions of the approved label. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of

off-label

uses. The federal government has levied large civil and criminal fines against companies for alleged improper promotion of

off-label

use and has enjoined companies from engaging in

off-label

promotion. The FDA and other regulatory agencies have also required that companies enter into consent decrees or permanent injunctions under which specified promotional conduct is changed or curtailed. Failure to comply with these requirements can result in, among other things, adverse publicity, warning letters, corrective advertising and potential civil and criminal penalties. FDA sanctions could include refusal to approve pending applications, withdrawal of an approval, clinical hold, warning or untitled letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, mandated corrective advertising or communications with doctors, debarment, restitution, disgorgement of profits, or civil or criminal penalties. Physicians may prescribe, in their independent professional and medical judgment, legally available products for uses that are not described in the product’s labeling and that differ from those tested and approved by the FDA. Such

off-label

uses are common across medical specialties. Physicians may believe that such

off-label

uses are the best treatment for many patients in varied circumstances. The FDA does not regulate the behavior of physicians in their choice of treatments. The FDA does, however, restrict manufacturer’s communications on the subject of

off-label

use of their products.

Biosimilars and Reference Product Exclusivity

The Affordable Care Act, signed into law in 2010, includes a subtitle called the Biologics Price Competition and Innovation Act, or BPCIA, which created an abbreviated approval pathway for biological products that are biosimilar to or interchangeable with an

FDA-licensed

reference biological product. The FDA has issued several guidance documents outlining an approach to review and approval of biosimilars.

Biosimilarity, which requires that there be no clinically meaningful differences between the biological product and the reference product in terms of safety, purity and potency, can be shown through analytical studies, animal studies, and a clinical study or studies. Interchangeability requires that a product is biosimilar to the reference product and the product must demonstrate that it can be expected to produce the same clinical results as the reference product in any given patient and, for products that are administered multiple times to an individual, the biologic and the reference biologic may be alternated or switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference biologic. However, complexities associated with the larger, and often more complex, structures of biological products, as well as the processes by which such products are manufactured, pose significant hurdles to implementation of the abbreviated approval pathway that are still being worked out by the FDA.

Under the BPCIA, an application for a biosimilar product may not be submitted to the FDA until four years following the date that the reference product was first licensed by the FDA. In addition, the approval of a biosimilar product may not be made effective by the FDA until 12 years from the date on which the reference product was first licensed. During this

12-year

period of exclusivity, another company may still market a competing version of the reference product if the FDA approves a full BLA for the competing product containing that applicant’s own preclinical data and data from adequate and well-controlled clinical trials to demonstrate the safety, purity and potency of its product. The BPCIA also created certain exclusivity periods for biosimilars approved as interchangeable products. At this juncture, it is unclear whether products deemed “interchangeable” by the FDA will, in fact, be readily substituted by pharmacies, which are governed by state pharmacy law.

A biological product can also obtain pediatric market exclusivity in the United States. Pediatric exclusivity, if granted, adds six months to existing exclusivity periods and patent terms. This

six-month

exclusivity, which runs from the end of other exclusivity protection or patent term, may be granted based on the voluntary completion of a pediatric study in accordance with an

FDA-issued

“Written Request” for such a study. The BPCIA is complex and continues to be interpreted and implemented by the FDA. In addition, government proposals have sought to reduce the

12-year

reference product exclusivity period. Other aspects of the BPCIA, some of which may impact the BPCIA exclusivity provisions, have also been the subject of recent litigation. As a result, the ultimate impact, implementation, and impact of the BPCIA is subject to significant uncertainty.

Government Regulation Outside of the United States

In addition to regulations in the United States, we will be subject to a variety of regulations in other jurisdictions governing, among other things, clinical studies and any commercial sales and distribution of our products. Because biologically sourced raw materials are subject to unique contamination risks, their use may be restricted in some countries.

Whether or not we obtain FDA approval for a product, we must obtain the requisite approvals from regulatory authorities in foreign countries prior to the commencement of clinical studies or marketing of the product in those countries. Certain countries outside of the United States have a similar process that requires the submission of a clinical study application much like the IND prior to the commencement of human clinical studies. In the European Union, for example, a CTA must be submitted to each country’s national health authority and an independent ethics committee, much like the FDA and the IRB, respectively. Once the CTA is approved in accordance with a country’s requirements, clinical study development may proceed.

The requirements and process governing the conduct of clinical studies, product licensing, pricing and reimbursement vary from country to country. In all cases, the clinical studies are conducted in accordance with

285

Table of Contents

GCP and the applicable regulatory requirements and the ethical principles that have their origin in the Declaration of Helsinki.

To obtain regulatory approval of an investigational biological product under European Union regulatory systems, we must submit a marketing authorization application. The application used to file the BLA in the United States is similar to that required in the European Union, with the exception of, among other things, country-specific document requirements. The European Union also provides opportunities for market exclusivity. For example, in the European Union, upon receiving marketing authorization, new chemical entities generally receive eight years of data exclusivity and an additional two years of market exclusivity. If granted, data exclusivity prevents regulatory authorities in the European Union from referencing the innovator’s data to assess a generic application. During the additional

two-year

period of market exclusivity, a generic marketing authorization can be submitted, and the innovator’s data may be referenced, but no generic product can be marketed until the expiration of the market exclusivity. However, there is no guarantee that a product will be considered by the European Union’s regulatory authorities to be a new chemical entity, and products may not qualify for data exclusivity. Products receiving orphan designation in the European Union can receive ten years of market exclusivity, during which time no similar medicinal product for the same indication may be placed on the market. An orphan product can also obtain an additional two years of market exclusivity in the European Union for pediatric studies. No extension to any supplementary protection certificate can be granted on the basis of pediatric studies for orphan indications.

The criteria for designating an “orphan medicinal product” in the European Union are similar in principle to those in the United States. Under Article 3 of Regulation (EC) 141/2000, a medicinal product may be designated as orphan if (1) it is intended for the diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition; (2) either (a) such condition affects no more than five in 10,000 persons in the European Union when the application is made, or (b) the product, without the benefits derived from orphan status, would not generate sufficient return in the European Union to justify investment; and (3) there exists no satisfactory method of diagnosis, prevention or treatment of such condition authorized for marketing in the European Union, or if such a method exists, the product will be of significant benefit to those affected by the condition, as defined in Regulation (EC) 847/2000. Orphan medicinal products are eligible for financial incentives such as reduction of fees or fee waivers and are, upon grant of a marketing authorization, entitled to ten years of market exclusivity for the approved therapeutic indication. The application for orphan drug designation must be submitted before the application for marketing authorization. The applicant will receive a fee reduction for the marketing authorization application if the orphan drug designation has been granted, but not if the designation is still pending at the time the marketing authorization is submitted. Orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process.

The

10-year

market exclusivity may be reduced to six years if, at the end of the fifth year, it is established that the product no longer meets the criteria for orphan designation, for example, if the product is sufficiently profitable not to justify maintenance of market exclusivity. Additionally, marketing authorization may be granted to a similar product for the same indication at any time if:

•

The second applicant can establish that its product, although similar, is safer, more effective or otherwise clinically superior;

•

The applicant consents to a second orphan medicinal product application; or

•

The applicant cannot supply enough orphan medicinal product.

For other countries outside of the European Union, such as countries in Eastern Europe, Latin America or Asia, the requirements governing the conduct of clinical studies, product licensing, pricing and reimbursement vary from country to country. In all cases, again, the clinical studies are conducted in accordance with GCP and the applicable regulatory requirements and the ethical principles that have their origin in the Declaration of Helsinki.

Table of Contents

If we fail to comply with applicable foreign regulatory requirements, we may be subject to, among other things, fines, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution.

Other Healthcare Laws

Pharmaceutical companies are subject to additional healthcare regulation and enforcement by the federal government and by authorities in the states and foreign jurisdictions in which they conduct their business and may constrain the financial arrangements and relationships through which we research, as well as, sell, market and distribute any products for which we obtain marketing approval. Such laws include, without limitation, federal and state anti-kickback, fraud and abuse, false claims, data privacy and security and physician and other health care provider transparency laws and regulations.

In order to distribute products commercially, we must also comply with state laws that require the registration of manufacturers and wholesale distributors of pharmaceutical products in a state, including, in certain states, manufacturers and distributors who ship products into the state even if such manufacturers or distributors have no place of business within the state. Some states also impose requirements on manufacturers and distributors to establish the pedigree of product in the chain of distribution, including some states that require manufacturers and others to adopt new technology capable of tracking and tracing product as it moves through the distribution chain. Several states have enacted legislation requiring pharmaceutical companies to establish marketing compliance programs, file periodic reports with the state, make periodic public disclosures on sales, marketing, pricing, track and report gifts, compensation and other remuneration made to physicians and other healthcare providers, clinical trials and other activities, and/or register their sales representatives, as well as to prohibit pharmacies and other healthcare entities from providing certain physician prescribing data to pharmaceutical companies for use in sales and marketing, and to prohibit certain other sales and marketing practices. All of our activities are potentially subject to federal and state consumer protection and unfair competition laws.

If our operations are found to be in violation of any of the federal and state healthcare laws described above or any other governmental regulations that apply to us, we may be subject to penalties, including without limitation, civil, criminal and/or administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from participation in government programs, such as Medicare and Medicaid, injunctions, private “qui tam” actions brought by individual whistleblowers in the name of the government, or refusal to allow us to enter into government contracts, contractual damages, reputational harm, administrative burdens, diminished profits and future earnings, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations. For information regarding risks related to these compliance requirements, see the section titled “Risk Factors—Risks Related to Government Regulations.”

Coverage and Reimbursement

Sales of any product depend, in part, on the extent to which such product will be covered by third-party payors, such as federal, state, and foreign government healthcare programs, commercial insurance and managed healthcare organizations, and the level of reimbursement for such product by third-party payors. Decisions regarding the extent of coverage and amount of reimbursement to be provided are made on a

plan-by-plan

basis. These third-party payors are increasingly reducing coverage and reimbursement for medical products, drugs and services. Obtaining coverage and adequate reimbursement for our product candidates may be particularly difficult because of the higher prices often associated with drugs administered under the supervision of a physician. Similarly, because our product candidates are physician-administered, separate reimbursement for the product itself may or may not be available. Instead, the administering physician may or may not be reimbursed for providing the treatment or procedure in which our product is used.

In addition, the U.S. government, state legislatures and foreign governments have continued implementing cost-containment programs, including price controls, restrictions on coverage and reimbursement and

287

Table of Contents

requirements for substitution of generic products. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit sales of any product. Decreases in third-party reimbursement for any product or a decision by a third-party payor not to cover a product could reduce physician usage and patient demand for the product and also have a material adverse effect on sales.

Healthcare Reform

Payors, whether domestic or foreign, or governmental or private, are developing increasingly sophisticated methods of controlling healthcare costs and those methods are not always specifically adapted for new technologies such as gene therapy and therapies addressing rare diseases such as those we are developing. In both the United States and certain foreign jurisdictions, there have been a number of legislative and regulatory changes to the health care system that could impact our ability to sell our products profitably

In the United States, in March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, each as amended, collectively known as the ACA, was enacted, which substantially changed the way healthcare is financed by both governmental and private insurers, and significantly affected the pharmaceutical industry. The ACA contained a number of provisions, including those governing enrollment in federal healthcare programs, reimbursement adjustments and changes to fraud and abuse laws. For example, the ACA:

•

increased the minimum level of Medicaid rebates payable by manufacturers of brand name drugs from 15.1% to 23.1% of the average manufacturer price;

•

required collection of rebates for drugs paid by Medicaid managed care organizations;

•

required manufacturers to participate in a coverage gap discount program, under which they must now agree to offer 70 percent

point-of-sale

•

imposed a

non-deductible

annual fee on pharmaceutical manufacturers or importers who sell “branded prescription drugs” to specified federal government programs.

On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial challenge to the ACA brought by several states without specifically ruling on the constitutionality of the ACA. Prior to the Supreme Court’s decision, President Biden issued an Executive Order to initiate a special enrollment period from February 15, 2021 through August 15, 2021 for purposes of obtaining health insurance coverage through the ACA marketplace. The Executive Order also instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the ACA. It is unclear how other healthcare reform measures of the Biden administrations or other efforts, if any, to challenge repeal or replace the ACA, will impact our business.

Other legislative changes have been proposed and adopted in the United States since the Affordable Care Act was enacted. For example, on March 11, 2021, President Biden signed the American Rescue Plan Act of 2021 into law, which eliminates the statutory Medicaid drug rebate cap, currently set at 100% of a drug’s average manufacturer price, for single source and innovator multiple source drugs, beginning January 1, 2024. Further, in August 2011, the Budget Control Act of 2011, among other things, created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the legislation’s automatic reduction to several government programs, including aggregate reductions of Medicare payments to providers of 2% per fiscal year. These reductions went into effect in April 2013 and, due to

288

Table of Contents

subsequent legislative amendments to the statute, will remain in effect through 2030 unless additional action is taken by Congress. Pursuant to the Coronavirus Aid, Relief, and Economic Security Act, also known as the CARES Act, as well as subsequent legislation, these reductions have been suspended from May 1, 2020 through December 31, 2021 due to the

COVID-19

pandemic.

Further, on May 30, 2018, the Right to Try Act was signed into law. The law, among other things, provides a federal framework for certain patients to access certain investigational new drug products that have completed a Phase 1 clinical trial and that are undergoing investigation for FDA approval. Under certain circumstances, eligible patients can seek treatment without enrolling in clinical trials and without obtaining FDA permission under the FDA expanded access program. There is no obligation for a pharmaceutical manufacturer to make its drug products available to eligible patients as a result of the Right to Try Act.

Moreover, there has recently been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products, which has resulted in several Congressional inquiries, proposed and enacted legislation and executive orders issued by the previous administration designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drug products. The likelihood of success of these and other measures initiated by the previous administration is uncertain, particularly in light of the new Biden administration. It is also possible that additional governmental action is taken in response to the

COVID-19

pandemic. Individual states in the United States have also become increasingly active in implementing regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing.

Data Privacy and Security Laws

We also are or will become subject to privacy laws in the jurisdictions in which we are established or in which we sell or market our products or run clinical trials. For example, in Europe we are subject to the GDPR in relation to our collection, control, processing and other use of personal data (i.e., data relating to an identifiable living individual). We process personal data in relation to participants in our clinical trials in the EEA, including health and medical information of these participants. The GDPR also provides that individual EEA countries may introduce further conditions of their own, including limitations which could limit our ability to collect, use and share personal data.

The GDPR imposes onerous accountability obligations requiring data controllers and processors to maintain a record of their data processing and implement policies as part of its mandated privacy governance framework. It also requires data controllers to be transparent and disclose to data subjects (in a concise, intelligible and easily accessible form) how their personal information is to be used; imposes limitations on retention of personal data; defines pseudonymized (i.e.,

key-coded)

data; introduces mandatory data breach notification requirements; and sets higher standards for data controllers to demonstrate that they have obtained valid consent for certain data processing activities. Fines for certain breaches of the GDPR are significant: up to the greater of €20 million or 4% of total global annual turnover. A breach of the GDPR or other applicable privacy and data protection laws and regulations could also result in regulatory investigations, reputational damage, orders to cease/change our use of data, enforcement notices, or potential civil claims including class action type litigation. Further, from January 1, 2021, we have to comply with the GDPR and separately the UK GDPR, which, together with the amended UK Data Protection Act 2018, retains the GDPR in UK national law. The GDPR and the UK GDPR each have the ability to fine up to the greater of €20 million/ £17 million or 4% of global turnover. Further, the relationship between the United Kingdom and the European Union in relation to certain aspects of data protection law remains unclear, including how data transfers between European Union member states and the United Kingdom will be treated and how United Kingdom data protection laws and regulations will develop in the medium to longer term. Currently there is a four to

six-month

grace period agreed in the European Union and

289

Table of Contents

United Kingdom Trade and Cooperation Agreement, ending June 30, 2021 at the latest, whilst the parties discuss an adequacy decision. The European Commission published a draft adequacy decision on February 19, 2021. If adopted, the decision will enable data transfers from European Union member states to the United Kingdom for a four-year period, subject to subsequent extensions. These changes may lead to additional compliance costs and could increase our overall risk.

In addition, the GDPR places restrictions on cross-border data transfers. Certain aspects of cross-border data transfers under the GDPR are uncertain as the result of legal proceedings in the European Union, including a recent decision by the Court of Justice for the European Union that invalidated the

EU-U.S.

Privacy Shield and, to some extent, called into question the efficacy and legality of using standard contractual clauses. This may increase the complexity of transferring personal data across borders. The GDPR will increase our responsibility and liability in relation to personal data that we process where such processing is subject to the GDPR, and we may be required to put in place additional mechanisms to ensure compliance with the GDPR, including as implemented by individual countries. We are also subject to European Union rules with respect to cross-border transfers of personal data out of the EEA. Recent legal developments in the European Union have created complexity and uncertainty regarding transfers of personal data from the EEA to other countries whose data protection standards have not been deemed “adequate” by the European Commission (including the United States). On July 16, 2020, the Court of Justice of the European Union, or CJEU, invalidated the

EU-US

Privacy Shield Framework, or Privacy Shield, under which personal data could be transferred from the EEA to US entities who had self-certified under the Privacy Shield scheme. While the CJEU upheld the adequacy, subject to certain conditions, of the standard contractual clauses (a standard form of contract approved by the European Commission as an adequate personal data transfer mechanism), future regulatory guidance could result in changes to the use of standard contractual clauses. As supervisory authorities issue further guidance on personal data export mechanisms, including circumstances where the standard contractual clauses cannot be used, and/or start taking enforcement action, we could suffer additional costs, complaints and/or regulatory investigations or fines, and/or if we are otherwise unable to transfer personal data between and among countries and regions in which we operate, it could affect the manner in which we provide our services, the geographical location or segregation of our relevant systems and operations, and could adversely affect our financial results.

Further, the exit of the United Kingdom, or UK, from the European Union, often referred to as Brexit, has created uncertainty with regard to data protection regulation in the UK. Specifically, the UK exited the European Union on January 1, 2020, subject to a transition period that ended December 31, 2020. Under the post-Brexit Trade and Cooperation Agreement between the European Union and the UK, the UK and European Union have agreed that transfers of personal data to the UK from EEA member states will not be treated as ‘restricted transfers’ to a

non-EEA

country for a period of up to four months from January 1, 2021, plus a potential further two months extension, or the Extended Adequacy Assessment Period. Although the current maximum duration of the Extended Adequacy Assessment Period is six months, it may end sooner, for example, in the event that the European Commission adopts an adequacy decision in respect of the UK, or the UK amends the UK GDPR and/or makes certain changes regarding data transfers under the UK GDPR/Data Protection Act 2018 without the consent of the European Union (unless those amendments or decisions are made simply to keep relevant UK laws aligned with the European Union’s data protection regime). If the European Commission does not adopt an ‘adequacy decision’ in respect of the UK prior to the expiry of the Extended Adequacy Assessment Period, from that point onwards the UK will be an ‘inadequate third country’ under the GDPR and transfers of personal data from the EEA to the UK will require a ‘transfer mechanism’ such as the Standard Contractual Clauses.

In the United States, numerous federal and state laws and regulations, including data breach notification laws, health information privacy and security laws, including HIPAA, and federal and state consumer protection laws and regulations (e.g., Section 5 of the Federal Trade Commission Act) that govern the collection, use, disclosure, and protection of health-related and other personal information could apply to our operations or the operations of our partners. In addition, certain state laws govern the privacy and security of personal information, including health-related information in certain circumstances, some of which are more stringent than HIPAA and many of which differ from each other in significant ways and may not have the same effect, thus complicating

290

Table of Contents

compliance efforts. For example, California enacted the CCPA, which creates individual privacy rights for California consumers (as defined in the law) and places increased privacy and security obligations on entities handling certain personal data of consumers or households. The CCPA requires covered companies to provide new disclosure to consumers about such companies’ data collection, use and sharing practices, provide such consumers new ways to

opt-out

of certain sales or transfers of personal information, and provide consumers with additional causes of action. The CCPA provides for civil penalties for violations, as well as a private right of action for certain data breaches that result in the loss of personal information. This private right of action may increase the likelihood of, and risks associated with, data breach litigation. The CCPA became effective on January 1, 2020, and (a) allows the California Attorney General to impose civil penalties for violations and (b) authorizes private lawsuits to recover statutory damages for certain data breaches. In addition, laws in all 50 U.S. states require businesses to provide notice to consumers whose personal information has been disclosed as a result of a data breach. State laws are changing rapidly and there is discussion in the U.S. Congress of a new comprehensive federal data privacy law to which we would become subject if it is enacted. The CCPA may impact our business activities and exemplifies the vulnerability of our business to the evolving regulatory environment related to personal data and protected health information. Additionally, a new privacy law, the California Privacy Rights Act, or CPRA, recently passed in California. The CPRA significantly modifies the CCPA and imposes additional data protection obligations on covered businesses, including additional consumer rights processes, limitations on data uses, new audit requirements for higher risk data, and opt outs for certain uses of sensitive data. It will also expand the types of data breaches subject to the CCPA’s private right of action, provide for increased penalties for CPRA violations concerning California residents under the age of 16 and create a new California data protection agency authorized to issue substantive regulations, and could result in increased privacy and information security enforcement. The majority of the provisions will go into effect on January 1, 2023, and additional compliance investment and potential business process changes may be required. Ensuring compliance with the CPRA could require us to incur additional costs and expenses.

In order to distribute products commercially, we must comply with state laws that require the registration of manufacturers and wholesale distributors of pharmaceutical products in a state, including, in certain states, manufacturers and distributors who ship products into the state even if such manufacturers or distributors have no place of business within the state. Some states also impose requirements on manufacturers and distributors to establish the pedigree of product in the chain of distribution, including some states that require manufacturers and others to adopt new technology capable of tracking and tracing product as it moves through the distribution chain. Several states have enacted legislation requiring pharmaceutical companies to establish marketing compliance programs, file periodic reports with the state, make periodic public disclosures on sales, marketing, pricing, track and report gifts, compensation and other remuneration made to physicians and other healthcare providers, clinical trials and other activities, and/or register their sales representatives, as well as to prohibit pharmacies and other healthcare entities from providing certain physician prescribing data to pharmaceutical companies for use in sales and marketing, and to prohibit certain other sales and marketing practices. All of our activities are potentially subject to federal and state consumer protection and unfair competition laws.

If our operations are found to be in violation of any of the federal and state healthcare and privacy laws described above or any other governmental regulations that apply to us, we may be subject to penalties, including without limitation, civil, criminal and/or administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from participation in government programs, such as Medicare and Medicaid, injunctions, private “qui tam” actions brought by individual whistleblowers in the name of the government, or refusal to allow us to enter into government contracts, contractual damages, reputational harm, administrative burdens, diminished profits and future earnings, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations. For information regarding risks related to these compliance requirements, see the section titled “Risk Factors—Risks Related to Government Regulation.”

Facilities

Our corporate headquarters are located in South San Francisco, California, where we lease approximately 40,000 square feet of office and research and development space pursuant to a lease agreement which commenced on April 25, 2019 and expires on April 30, 2027, with an option to extend for eight years. In Alameda, California, we lease approximately 92,000 square feet of space pursuant to a lease agreement which initiated on June 3, 2021 and expires on September 30, 2032, with two options to extend for five years each. Within this space, we have begun the

build-out

of a cell therapy manufacturing facility designed to meet Current Good Manufacturing Practices (cGMP) with the goal of providing clinical and commercial-scale manufacturing for multiple allogeneic, or

“off-the-shelf”,

chimeric antigen receptor (CAR) natural killer (NK) cell product candidates. We believe that our existing facilities are suitable and adequate for our needs.

Employees and Human Capital Resources

As of December 16, 2021, we had 89 employees, all of whom were full-time, consisting of clinical, research, operations, regulatory, finance and business development personnel. 28 of our employees hold Ph.D. or M.D. degrees. None of our employees are subject to a collective bargaining agreement. We consider our relationship with our employees to be good.

Our human capital resources objectives include, as applicable, identifying, recruiting, retaining, incentivizing and integrating our existing and additional employees. The principal purposes of our equity incentive plans are to attract, retain and motivate selected employees, consultants and directors through the granting of stock-based compensation awards, in order to increase stockholder value and the success of our company by motivating such individuals to perform to the best of their abilities and achieve our objectives.

Legal Proceedings

From time to time, we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. We are not currently a party to any material legal proceedings. Regardless of outcome, such proceedings or claims can have an adverse impact on us because of defense and settlement costs, diversion of resources and other factors, and there can be no assurances that favorable outcomes will be obtained.

Overview

Senti is a preclinical biotechnology company developing next-generation cell and gene therapies engineered with its gene circuit platform technologies to fight challenging diseases. Senti’s mission is to create a new generation of smarter therapies that can outmaneuver complex diseases in ways previously not implemented by conventional medicines. To accomplish this mission, Senti has built a synthetic biology platform that it believes may enable it to program next-generation cell and gene therapies with what it refers to as “gene circuits.” These gene circuits, which Senti created from novel and proprietary combinations of genetic parts, are designed to reprogram cells with biological logic to sense inputs, compute decisions and respond to their respective cellular environments. Senti aims to design and optimize gene circuits through its Design-Build-Test- Learn Engine or DBTL Engine, to improve the “intelligence” of cell and gene therapies in order to enhance their therapeutic effectiveness against a broad range of diseases that conventional medicines are unable to address. Senti’s gene circuit platform technologies can be applied in a modality-agnostic manner, with applicability to natural killer (NK) cells, T cells, tumor infiltrating lymphocytes (TILs), stem cells including Hematopoietic Stem Cells (HSCs), in vivo gene therapy and messenger ribonucleic acid (mRNA). All of Senti’s current product candidates are in preclinical development. Senti’s lead product candidates utilize allogeneic chimeric antigen receptor (CAR) NK cells outfitted with its gene circuit technologies in several oncology indications with currently high unmet need. Senti expects to file investigational new drug applications, or INDs, for multiple product candidates starting in 2023.

Since our inception, we have funded our operations almost exclusively with proceeds from the sale and issuance of shares of our redeemable convertible preferred stock and debt financings, and we have devoted substantially all of our resources to organizing and staffing our company, business planning, raising capital, developing and optimizing our platform technologies, identifying potential product candidates, undertaking research and preclinical studies and clinical trial planning activities, engaging in manufacturing for our development programs, establishing and enhancing our intellectual property portfolio, and providing general and administrative support for these operations. Through September 30, 2021 (unaudited), we have received gross proceeds of $158.1 million from sales of our redeemable convertible preferred stock including borrowings under convertible notes, which converted into redeemable convertible preferred stock in 2018 and 2020.

293

Table of Contents

We have incurred net losses of $44.4 million and $18.8 million for the nine months ended September 30, 2021 and 2020 (unaudited), respectively, and net losses of $19.9 million and $21.2 million for the years ended December 31, 2020 and 2019, respectively. We expect to continue to incur significant losses for the foreseeable future. As of September 30, 2021 (unaudited), we had cash and cash equivalents of $73.7 million, and an accumulated deficit of $104.2 million.

We anticipate that our expenses and operating losses will increase substantially over the foreseeable future. The expected increase in expenses will be driven in large part by our ongoing activities, if and as we:

•

continue to advance our gene circuit platform technologies;

•

continue preclinical development of our current and future product candidates and initiate additional preclinical studies;

•

commence clinical studies of our current and future product candidates;

•

establish our manufacturing capability, including developing our contract development and manufacturing relationships, and building our internal manufacturing facilities;

•

acquire and license technologies aligned with our gene circuit platform technologies;

•

seek regulatory approval of our current and future product candidates;

•

expand our operational, financial, and management systems and increase personnel, including personnel to support our preclinical and clinical development, manufacturing and commercialization efforts;

•

continue to develop, grow, perfect, and defend our intellectual property portfolio; and

•

incur additional legal, accounting, or other expenses in operating our business, including the additional costs associated with operating as a public company.

In addition, in 2021, we began construction on a dedicated

in-house,

state-of-the-art

current good manufacturing practices “cGMP” facility to support clinical and commercial-scale production of multiple allogeneic NK cell product candidates. We anticipate that this facility will become operational in time to support initial clinical trials for our lead product candidates. Our manufacturing facility is designed to leverage the latest cell therapy process technologies as we strive to maximize scalability and minimize cost of goods.

The global

COVID-19

pandemic continues to evolve, and we will continue to monitor it closely. The extent of the impact of the

COVID-19

pandemic on our business, operations, and development timelines and plans remains uncertain and will depend on certain developments, including the duration and spread of the outbreak and any new variants, and its impact on our anticipated clinical trial plans, CROs, contract manufacturing organizations, and other third parties with whom we do business. To date, we have not experienced delays in our discovery and development activities as a result of the

COVID-19

pandemic. However, we cannot be sure that we will not experience delays or challenges in the future. We will continue to actively monitor the situation related to

COVID-19

and may take further actions that alter our operations, including those that may be required by federal, state, or local authorities, or that we determine are in the best interests of our employees and other third parties with whom we do business.

As of April 12, 2021, the issuance date of the consolidated financial statements for the year ended December 31, 2020, the Company concluded that substantial doubt existed about the Company’s ability to continue as a going concern for one year from the issuance date of the annual consolidated financial statements. In light of these concerns, our independent registered public accounting firm included in its opinion for the year ended December 31, 2020 an explanatory paragraph expressing substantial doubt about our ability to continue as a going concern within one year from April 12, 2021.

We believe that our cash and cash equivalents on hand as of September 30, 2021 (unaudited) are not sufficient to fund our operations for the next twelve months from the date of this proxy statement/prospectus.

Recent Developments

Pending Merger with Dynamics Special Purpose Corp.

On December 19, 2021, we entered into a definitive Business Combination Agreement with Dynamics Special Purpose Corp. (“DYNS”), a publicly traded special purpose acquisition company (“SPAC”). Under the terms of the proposed transaction, we will merge with DYNS at an estimated combined enterprise value of approximately $276 million. The cash components of the transaction will be funded by DYNS’ cash in trust of $230.0 million (assuming no redemptions) as well as a $66.8 million private placement of common stock at $10.00 per share from various accredited investors.

On February 12, 2022, we entered into Amendment No. 1 to the Business Combination Agreement to restructure certain option grants made at the time the Business Combination Agreement was signed.

Components of Results of Operations

Total Revenue

We currently have no therapeutic products approved for sale, and we have never generated any revenue from the sale of any therapeutic products. Total revenue consists of contract revenue related to research services provided to customers and grant income which is research funding received from grants.

Our ability to generate product revenues will depend on our partners’ ability to replicate our results and the successful development and eventual commercialization of our product candidates, which we do not expect for the foreseeable future, if ever. We may also look to generate revenue from collaboration and license agreements in the future.

Operating Expenses

Our operating expenses consist of research and development expense and general and administrative expenses.

Research and Development Expenses

Research and development costs consist primarily of costs incurred for the discovery and preclinical development of our product candidates, which include:

•

employee-related expenses, including salaries, related benefits, and stock-based compensation expenses for employees engaged in research and development functions;

•

expenses incurred in connection with manufacturing, process development, research, laboratory consumables and preclinical studies;

•

the cost of consultants engaged in research and development related services and the cost to manufacture drug products for use in our preclinical studies and trials;

•

facilities, depreciation and other expenses, which include allocated expenses for rent and maintenance of facilities, insurance and supplies;

•

costs related to regulatory compliance; and

•

the cost of annual license fees.

We have not historically tracked research and development expenses by program, with the exception of third-party research projects. We have various ongoing early stage research and product candidate discovery projects and going forward, we expect to have various products undergoing clinical trials. Our internal resources,

295

Table of Contents

employees and infrastructure are not directly tied to any one research or product candidate discovery project and are typically deployed across multiple projects. As such, we do not maintain information regarding these costs incurred for these early stage research and product candidate discovery programs on a project-specific basis.

Our direct external development program expenses reflect external costs attributable to our preclinical development candidates selected for further development as well as INDs and clinical development. Such expenses include third-party contract costs relating to manufacturing, clinical trial activities, translational medicine and toxicology activities. We do not allocate internal research and development costs which include personnel, facility costs, laboratory consumables and discovery and research related activities associated with our pipeline because these costs are deployed across multiple programs and our platform, and, as such, are not separately classified.

Research and development expenses consisted of the following (in thousands):

Total	$	15,548	$	12,400	$	15,956	$	14,524

Research and development activities are central to our business model. There are numerous factors associated with the successful commercialization of any of our product candidates, including future trial design and various regulatory requirements, many of which cannot be determined with accuracy at this time based on our stage of development. In addition, future regulatory factors beyond our control may impact our preclinical development programs. Product candidates in clinical development generally have higher development costs than those in preclinical stages of development, primarily due to the increased size and duration of clinical trials. At this time, we cannot reasonably estimate or know the nature, timing and costs of the efforts that will be necessary to complete the preclinical development of any of our product candidates. However, we expect that our research and development expenses and manufacturing costs will increase substantially in connection with our planned preclinical and clinical development activities in the near term and in the future.

The successful development of our current and future product candidates is highly uncertain. This is due to numerous risks and uncertainties, including the following:

•

negative or inconclusive results from our preclinical or clinical trials or the clinical trials of others for product candidates similar to ours, leading to a decision or requirement to conduct additional preclinical studies or clinical trials or abandon any or all of our programs;

•

product-related side effects experienced by participants in our clinical trials or by individuals using therapeutics similar to our product candidates;

•

delays in submitting IND applications or comparable foreign applications, or delays or failures to obtain the necessary approvals from regulators to commence a clinical trial, or a suspension or termination of a clinical trial once commenced;

•

conditions imposed by the FDA or other regulatory authorities regarding the scope or design of our clinical trials;

•

delays in enrolling research subjects in clinical trials;

296

Table of Contents

•

high

drop-out

rates of research subjects;

•

inadequate supply or quality of product candidate components or materials or other supplies necessary for the conduct of our clinical trials;

•

chemistry, manufacturing and control challenges associated with manufacturing and scaling up biologic product candidates to ensure consistent quality, stability, purity and potency among different batches used in clinical trials;

•

greater-than-anticipated clinical trial costs;

•

poor potency or effectiveness of our product candidates during clinical trials;

•

unfavorable FDA or other regulatory authority inspection and review of a clinical trial or manufacturing site;

•

delays as a result of the

COVID-19

pandemic or events associated with the pandemic;

•

failure of our third-party contractors or investigators to comply with regulatory requirements or otherwise meet their contractual obligations in a timely manner, or at all;

•

delays and changes in regulatory requirements, policies and guidelines; and

•

the FDA or other regulatory authorities interpreting our data differently than we do.

A change in the outcome of any of these variables may significantly impact the costs and timing associated with the development of our product candidates. We may never succeed in obtaining regulatory approval for any of our product candidates.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and employee-related costs, including stock-based compensation, for personnel in executive, finance and other administrative functions. Other significant costs include legal fees relating to corporate matters, professional fees for accounting and consulting services and an allocation of facility-related costs.

We expect our general and administrative expenses will increase for the foreseeable future to support our increased research and development, manufacturing activities, and preclinical and clinical activities and to reflect increased costs associated with operating as a public company. These increased costs will likely include increased expenses for audit, legal, regulatory, tax and related services associated with maintaining compliance with exchange listing and SEC requirements, director and officer insurance premiums and investor relations costs.

Other Income (Expense)

Interest Income, net

Interest income, net consists of interest earned on our cash and cash equivalents, and short-term investments, if any, held during the year.

Change in Fair Value of Convertible Notes

Our convertible notes have been accounted for at fair value with changes in fair value recorded in earnings at each reporting period through settlement.

Change in Preferred Stock Tranche Liability

Our preferred stock tranche liability has been accounted for at fair value with changes in the fair value recorded in earnings at each reporting period through settlement.

Contract revenue

. For the nine months ended September 30, 2021 and 2020, we generated revenue from contracts and license agreements of $1.7 million and $0.5 million, respectively. The increase of $1.3 million was due primarily to a new collaboration agreement entered into in 2021 which led to the recognition of $1.7 million in incremental revenue, partially offset by a $0.4 million decrease in the revenue generated from an existing contract and license agreement, commensurate with decreased research services performed.

Grant income

. For the nine months ended September 30, 2021 and 2020, we generated revenue from grants of $0.2 million and $0.1 million, respectively. The increase of $0.1 million was primarily due to the recognition of revenue related to the Small Business Innovation Research (“SIBR”)

SENTI-202

grant funding.

Research and development expenses

. Research and development expenses were $15.5 million and $12.4 million for the nine months ended September 30, 2021 and 2020, respectively. The increase of $3.1 million was primarily due to increase of $1.9 million in lab service costs, $0.8 million in facility costs, $0.2 million in personnel-related expenses, $0.1 million in depreciation expenses and $0.1 million in professional services costs.

General and administrative expenses

. General and administrative expenses were $16.0 million and $6.3 million for the nine months ended September 30, 2021 and 2020, respectively. The increase of $9.7 million was primarily due to increases of $2.6 million in professional services related to legal and accounting services, $2.2 million related to incremental processional, legal and accounting services expenses incurred in connection with the suspended Initial Public Offering (“IPO”), $3.1 million in personnel-related expenses, $1.2 million in stock-based compensation, $0.4 million in facility costs and $0.1 million in costs related to a new directors and officers insurance policy.

298

Table of Contents

Interest income, net

. Interest income was negligible and $0.1 million for the nine months ended September 30, 2021 and 2020, respectively, due to greater interest earned in 2020 on higher invested balances.

Change in fair value of convertible note

. In August 2020, we recognized an initial loss on the recognition of the convertible note of $0.9 million and thereafter recognized a fair value gain adjustment that reduced the convertible note liability by $0.2 million. There was no equivalent expense during the nine months ended September 30, 2021.

Change in preferred stock tranche liability

. For the nine months ended September 30, 2021, we recognized a loss of $14.7 million as an adjustment to the preferred stock tranche liability. The adjustment stems primarily from the increase in management’s estimate of the fair value of our Series B redeemable convertible preferred stock resulting from a decrease in time to liquidity as we drew nearer to completing an exit strategy.

There was no equivalent liability outstanding during the nine months ended September 30, 2020.

Comparison of the Years Ended December 31, 2020 and 2019

The following table summarizes our results of operations for the years ended December 31, 2020 and 2019 (in thousands):

Total other income (expense), net		4,832			625			4,207

Net loss	$	(19,862	)	$	(21,157	)	$	1,295

Contract revenue. For the years ended December 31, 2020 and 2019, we generated revenue from a contract and license agreement of $0.4 million and $0.1 million, respectively, commensurate with increased research services performed. Immaterial costs incurred in performing the research services under this agreement were recorded as research and development expense in our consolidated financial statements.

Grant income. For the years ended December 31, 2020 and 2019, we generated revenue from grants of $0.2 million and nil, respectively.

Research and development expenses. Research and development expenses were $16.0 million and $14.5 million for the years ended December 31, 2020 and 2019, respectively. The increase of $1.4 million was

299

Table of Contents

primarily due to increases of $1.0 million in personnel-related expenses, $0.4 million in facility costs and $0.1 million in depreciation, offset by a decrease of $0.1 million of third-party research expenses related to our development programs.

General and administrative expenses. General and administrative expenses were $9.3 million and $7.3 million for the years ended December 31, 2020 and 2019, respectively. The increase of $2.0 million was primarily due to increases of $1.1 million in personnel-related expenses, $0.6 million in professional services related to accounting services, corporate legal fees, other consulting and patent legal fees, and $0.3 million in facility costs and insurance.

Interest income, net. Interest income was $0.1 million and $0.7 million for the years ended December 31, 2020 and 2019, respectively. The decrease of $0.6 million was due to lower interest earned on invested balances.

Change in fair value of convertible note. In August 2020, we recognized an initial loss on the recognition of the convertible note of $0.9 million and thereafter recognized a fair value gain adjustment that reduced the convertible note liability by $0.2 million. There was no equivalent expense during the year ended December 31, 2019.

Change in preferred stock tranche liability. In connection with issuances of shares of Series B redeemable convertible preferred stock in October and December 2020, we recognized an initial liability for the Series B preferred stock tranche feature of $6.1 million and $0.1 million, respectively. In December 2020, a gain of $5.7 million was recognized in other income (expense) as an adjustment to the preferred stock tranche liability, resulting in a balance of $0.4 million as of December 31, 2020. The change in value is mainly due to the composition of the investors that held the tranche feature and a change in fair value between the measurement dates. On October 22, 2020, the rights to participate in the subsequent tranches were held primarily by the investors that had control over exercising such rights. On December 28, 2020, certain investors forfeited their rights to participate in the future tranches. In their place, new investors acquired the same tranche rights, but lacked control over when the tranche rights could be exercised. The lack of control over exercising these tranche rights significantly devalued the feature and resulted in a reduction in the associated fair value of the preferred stock tranche liability. The preferred stock tranche liability was valued as a call option as of October 22, 2020, while the December 28, 2020 valuation also incorporated a forward contract.

There was no equivalent liability outstanding during the year ended December 31, 2019.

Liquidity and Capital Resources

Sources of Liquidity

From inception to September 30, 2021 (unaudited), we raised aggregate gross proceeds of $158.1 million from the issuance of shares of our redeemable convertible preferred stock and the issuance of convertible notes.

We do not have any products approved for sale and have not generated any revenue from product sales or otherwise. We have incurred net losses and negative cash flows from operations since our inception and anticipate we will continue to incur net losses for the foreseeable future. As of September 30, 2021 (unaudited), we had $73.7 million in cash and cash equivalents, and an accumulated deficit of $104.2 million, respectively.

We will need substantial additional funding to support our continuing operations and pursue our development strategy. Until such time as we can generate significant revenue from sales of our product candidates, if ever, we expect to finance our operations through the sale of equity, debt financings or other capital sources, including potential collaborations with other companies or other strategic transactions. Adequate funding may not be available to us on acceptable terms, if at all. Should we fail to raise capital or enter into such agreements as, and when, needed, we may have to significantly delay, scale back, or discontinue the development

and commercialization of our product candidates or delay our efforts to expand our product pipeline. We may also be required to sell or license to other parties’ rights to develop or commercialize our product candidates that we would prefer to retain.

Cash Flows

The following table sets forth a summary of our cash flows for each of the periods indicated (in thousands):


	Nine Months Ended September 30,						Year Ended December 31,

Net (decrease) increase in cash and cash equivalents	$	44,190		$	2,976		$	25,236		$	(615	)

Operating Activities

For the nine months ended September 30, 2021, net cash used in operating activities of $22.7 million was primarily due to our net loss of $44.4 million with

non-cash

adjustments of $14.7 million for an increase in our estimated preferred stock tranche liability, $2.0 million for depreciation and amortization of operating lease

right-of-use

assets and $1.6 million for stock-based compensation expense, as well as a $2.2 million increase in deferred revenue, $4.1 million for an increase in accounts payable and accrued and other current liabilities offset by a decrease of $1.0 million in operating lease liabilities, an increase of $1.6 million in prepaid and other assets and an increase of $0.3 in accounts receivable. During the nine months ended September 30, 2021 the Company expensed $2.2 million of deferred offering costs related to the suspended IPO, of which $0.9 million was paid and is included in the net cash used in operating activities.

For the nine months ended September 30, 2020, net cash used in operating activities of $17.2 million was primarily due to our net loss of $18.8 million with

non-cash

adjustments of $1.5 million for depreciation and amortization of operating lease

right-of-use

assets and $0.7 million change in fair value of convertible notes, as well as a $0.3 million increase in accounts payable and accrued and other liabilities offset by a decrease of $1.0 million in operating lease liabilities.

For the year ended December 31, 2020, net cash used in operating activities of $24.2 million was primarily due to our net loss of $19.9 million with

non-cash

adjustments of $5.7 million for a reduction in the estimated fair value of our preferred stock tranche liability, $2.0 million for depreciation and amortization of operating lease

right-of-use

assets, and $0.7 million expense for the change in fair value of convertible notes as well as an decrease of $1.3 million in operating lease liabilities.

For the year ended December 31, 2019, net cash used in operating activities of $18.4 million was primarily due to our net loss of $21.2 million partially offset by $1.5 million increase in accounts payable and accrued and other liabilities, as well as by $1.4 million of

non-cash

charges for depreciation and amortization of operating lease

right-of-use

assets.

Investing Activities

For the nine months ended September 30, 2021, net cash used in investing activities of $1.6 million was due entirely to purchases of property and equipment.

301

Table of Contents

For the nine months ended September 30, 2020, net cash provided by investing activities of $12.2 million was due to the maturity of short-term investments of $13.0 million, partially offset by purchases of short-term investments of $0.4 million and purchases of property and equipment of $0.3 million.

For the year ended December 31, 2020, net cash provided by investing activities of $11.4 million was primarily due to the maturity and purchases of short-term investments of $12.5 million partially offset by purchases of property and equipment of $1.2 million.

For the year ended December 31, 2019, net cash provided by investing activities of $3.8 million was primarily due to the maturity and sales of short-term investments of $39.1 million partially offset by purchases of short-term investments of $33.4 million and $2.0 million of purchases of property and equipment.

Financing Activities

For the nine months ended September 30, 2021, net cash provided by financing activities of $68.4 million was primarily due to proceeds received of $67.0 million from the issuance of our Series B redeemable convertible preferred stock and $1.5 million from the issuance of common stock upon exercise of stock options.

For the nine months ended September 30, 2020, net cash provided by financing activities of $8.0 million was due entirely to the issuance of our Series B redeemable convertible preferred stock

For the year ended December 31, 2020, net cash provided by financing activities of $38.1 million was primarily due to proceeds received of $30.0 million from the issuance of our Series B redeemable convertible preferred stock and to $8.0 million received from the issuance of notes converted to Series B redeemable convertible preferred stock.

For the year ended December 31, 2019, net cash provided by financing activities of $14.0 million was primarily due to proceeds received of $14.0 million from the issuance of our Series A redeemable convertible preferred stock.

Funding Requirements

Based upon our current operating plans, we believe that our existing cash and cash equivalents will not be sufficient to fund our operations for the next twelve months from the date of this proxy statement/prospectus. However, as noted in the

Recent Developments

section above, the Company is seeking a potential business combination with Dynamics Special Purpose Corp. which would provide further liquidity to the Company and will be funded by DYNS’s cash in trust of $230.0 million (assuming no redemptions) as well as a $66.8 million private placement of common stock at $10.00 per share from various accredited investors. In the event the Company does not complete the proposed business combination, we anticipate that we will require additional funding though the precise timing of such needs may prove uncertain as our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement that involves risks and uncertainties, and actual results could vary materially. Our assumptions may prove to be inaccurate, and we could deplete our capital resources sooner than we expect. Additionally, the process of testing and manufacturing product candidates in preclinical studies and clinical trials is costly and the timing and expenses in these trials are uncertain.

Our future capital requirements will depend on many factors, including:

•

the scope, rate of progress, results and costs of platform development activities, preclinical development, laboratory testing and clinical trials for our product candidates;

•

the number and development requirements of product candidates that we may pursue, and other indications for our current product candidates that we may pursue;

302

Table of Contents

•

the costs, timing and outcome of regulatory review of our product candidates;

•

the scope and costs of constructing and operating our planned cGMP facility and any commercial manufacturing activities;

•

the cost associated with commercializing any approved product candidates;

•

the cost and timing of developing our ability to establish sales and marketing capabilities, if any;

•

the timing and amount of any milestone and royalty payments we are required to make under our present or future license agreements;

•

our ability to establish and maintain collaborations on favorable terms, if at all; and

•

the extent to which we acquire or

in-license

other product candidates and technologies and associated intellectual property.

In order to improve our liquidity, management is actively pursuing additional financing. We expect our expenses to increase substantially in connection with ongoing activities, particularly as we advance our preclinical activities and clinical trials for our product candidates in development. Accordingly, we will need to obtain substantial additional funding for continuing operations. If we are unable to raise capital when needed, or on attractive terms, we could be forced to delay, reduce or eliminate our research or drug development programs or any future commercialization efforts. Although management continues to pursue these plans, there is no assurance that we will be successful in obtaining sufficient funding on terms acceptable to us to fund continuing operations, if at all.

Accounting standards require that management evaluate whether we have adequate financial resources to continue as a going concern for one year after the date that these consolidated financial statements are available to be issued. Management has determined that additional funds will be needed to continue as a going concern for the period defined in the accounting standards.

Contractual Obligations and Commitments

The following table summarizes our contractual obligations and commitments at December 31, 2020 (in thousands):


	December 31, 2020
	Payments Due by Period
	Total		Less Than 1 Year		1 to 3 Years		4 to 5 Years		More Than 5 years
Lease commitments	$	18,438	$	2,669	$	5,602	$	5,974	$	4,193
Purchase commitments		1,384		1,076		308		—		—

Total	$	19,822	$	3,745	$	5,910	$	5,974	$	4,193

Except as noted below, there were no material changes to our contractual obligations and commitments during the nine months ended September 30, 2021 (unaudited).

On June 3, 2021, we entered into a lease agreement for a new cGMP facility in Alameda, California to support planned initial clinical trials for our product candidates (see Note 10 to our consolidated financial statements). The lease will expire in 2032 with future undiscounted operating lease payments of $46.0 million over an initial lease period of eleven years.

303

Table of Contents

In 2021, we began construction of the cGMP facility. As of September 30, 2021 (unaudited) we have paid $0.8 million in construction costs and the purchase commitments amounted to approximately $3.0 million. The agreements with the construction company provide for termination following a certain period after notice. Upon termination we will be responsible for payment for work performed to date.

During the nine months ended September 30, 2021 (unaudited), we entered into a three-year collaboration and option agreement with BlueRock Therapeutics LP (“BlueRock”) under which the Company granted BlueRock an option to execute an exclusive or

non-exclusive

license to develop, manufacture and commercialize cell therapy products (See Note 14 to our consolidated financial statements). In consideration for the option, the Company is responsible for up to $10.0 million in research and development costs and expenses associated with the collaboration R&S plan incurred over the three-year term.

As of September 30, 2021 (unaudited), purchase commitments amounted to approximately $5.0 million. The increase from December, 31, 2020 was primarily due to additional sponsored research agreements, license agreements and corporate headquarters construction costs.

We enter into contracts in the normal course of business with clinical supply manufacturers and with vendors for preclinical studies and other services and products for operating purposes. These contracts generally provide for termination after a short notice period, and, therefore, are cancellable contracts and not included in the table above.

We have also entered into license agreements under which we are obligated to make specified milestone and royalty payments. We have not included future payments under these agreements in the table of contractual obligations above since the payment obligations under these agreements are contingent upon future events, such as our achievement of specified development, regulatory, and sales milestones, or generating product sales. As of September 30, 2021 (unaudited), we were unable to estimate the timing or likelihood of achieving these milestones or generating future product sales.

Off-Balance

Sheet Arrangements

During the periods presented, we did not have, nor do we currently have, any

off-balance

sheet arrangements as defined under the rules and regulations of the SEC.

Critical Accounting Policies and Significant Judgments and Estimates

Our management’s discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP. The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities in our consolidated financial statements and accompanying notes. On an ongoing basis, we evaluate our estimates and judgments. We base our estimates and assumptions on historical experience, known trends and events, and various other factors that are believed to be reasonable and appropriate under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies are described in more detail in Note 2 to our consolidated financial statements included elsewhere in this proxy statement/prospectus, we believe the following accounting policies and estimates to be most critical to the preparation of our consolidated financial statements. We define our critical accounting policies as those under U.S. GAAP that require us to make subjective estimates and judgments about matters that are inherently uncertain and are likely to have a material impact on our financial condition and results of operations, as well as the specific manner in which we apply those principles.

Determination of the Fair Value of Common Stock

We are required to estimate the fair value of our common stock underlying our share-based awards when performing the fair value calculations using the Black-Scholes option pricing model. Because our common stock is not currently publicly traded, the fair value of our common stock underlying our share-based awards has been determined on each grant date by our board of directors, with input from management, considering our most recently available third-party valuation of our common stock.

In the absence of a public trading market for our common stock, on each grant date, our board of directors has made a reasonable determination of the fair value of our common stock based on the information known to us on the date of grant, upon a review of any recent events and their potential impact on the estimated fair value per share of the common stock, and timely valuations from an independent third-party valuation in accordance with guidance provided by the American Institute of Certified Public Accountants, Inc. Practice Aid:

Valuation

of Privately-Held-Company Equity Securities Issued as Compensation, 2013

. In addition, our board of directors considered various objective and subjective factors to determine the fair value of our common stock, including:

•

the estimated value of each security both outstanding and anticipated;

•

the anticipated capital structure that will directly impact the value of the currently outstanding securities;

•

our results of operations and financial position;

•

the status of our research and development efforts;

•

the composition of, and changes to, our management team and board of directors;

•

the lack of liquidity of our common stock as a private company;

•

our stage of development and business strategy and the material risks related to our business and industry;

•

external market conditions affecting the life sciences and biotechnology industry sectors;

•

U.S. and global economic conditions;

•

the results of independent third-party valuations of our common stock;

•

the likelihood of achieving a liquidity event for the holders of our common stock, such as an initial public offering or a sale of our company, given prevailing market conditions; and

•

the market value and volatility of comparable companies.

The Practice Aid identifies various available methods for allocating enterprise value across classes and series of capital stock to determine the estimated fair value of common stock at each valuation date. In accordance with the Practice Aid, we considered various income, market or asset valuation methods.

Based on our early stage of development and other relevant factors, we appropriately used different valuation methods including a hybrid of the option pricing method, or OPM, and guideline transactions Backsolve method, a hybrid of the OPM and guideline public company methods or a hybrid of OPM, Backsolve method, and Monte Carlo simulation to determine the estimated fair value of our common stock for valuations performed between February 2019 and September 30, 2021. In determining the estimated fair value of our common stock, our Board of Directors also considered the fact that our stockholders could not freely trade our common stock in the public markets. Accordingly, we applied discounts to reflect the lack of marketability of our common stock based on the weighted-average expected time to liquidity.

Our Board of Directors and management develop best estimates based on application of these approaches and the assumptions underlying these valuations, giving careful consideration to the advice from our third-party

305

Table of Contents

valuation expert. Such estimates involve inherent uncertainties and the application of significant judgment. As a result, if factors or expected outcomes change and we use significantly different assumptions or estimates, our equity-based compensation could be materially different.

Valuation of Preferred Stock Tranche Liability

Our Series B redeemable convertible preferred stock included an obligation whereby the investors agreed to buy, and the Company agreed to sell, additional shares at a fixed price if certain agreed-upon milestones were achieved or at the election of investors. This obligation was determined to be a freestanding financial instrument that should be accounted for as a liability at fair value, and until settlement, the preferred stock tranche liability was revalued at each reporting period with changes in the fair value recorded in earnings. Upon achieving specific milestones, and obtaining Board and stockholder approval, the tranches were called and settled on May 14, 2021. The liability was then extinguished and the fair value was reclassified to redeemable convertible preferred stock.

We utilized the Monte Carlo valuation model and/or Black-Scholes option pricing model which incorporated assumptions and estimates, to value the preferred stock tranche feature prior to its settlement. Significant estimates and assumptions impacting the fair value measurement included the estimated fair value per share of the underlying Series B redeemable convertible preferred stock, risk-free rate, expected dividend yield, time to liquidity, expected volatility of the price of the underlying preferred stock and determining the type of option (call option and/or forward contract) and associated probabilities. The most significant assumptions impacting the fair value of the preferred stock tranche feature included the estimated fair value of our Series B redeemable convertible preferred stock, estimated probability of and time to liquidity for going public and staying-private, and the determination of the type of option (call option and/or forward contract) and associated probability.

We determined the estimated fair value per share of the underlying redeemable convertible preferred stock by taking into consideration the most recent sales of our redeemable convertible preferred stock as well as additional factors that we deemed relevant. We assessed these assumptions and estimates on a quarterly basis as additional information impacting the assumptions became available. The risk-free rate was determined by reference to the U.S. Treasury yield curve for time periods approximately equal to the expected term of the preferred stock tranche feature. We estimated a 0% dividend yield based on the expected dividend yield and the fact that we have never paid or declared dividends. We estimated the time to liquidity by weighting potential timelines associated with reaching various pipeline milestones and completing an initial public offering. Historically, we have been a private company and lack company-specific and implied volatility information of our stock. Therefore, we estimated our expected stock volatility based on the historical volatility of a representative group of public companies in the biotechnology industry for the expected terms. The determination of the type of option is based on the payouts available to the holders of the tranche rights and the level of control the investors had over exercising these rights.

These estimates involved inherent uncertainties and the application of significant judgment. As a result, if factors or expected outcomes change and we used significantly different assumptions or estimates, our preferred stock tranche liability could be materially different.

Fair Value Option for Convertible Notes

We elected to account for our convertible notes at fair value in order to measure those liabilities at amounts that more accurately reflect the current economic environment in which the Company operates. We recorded the convertible notes at fair value with changes in fair value recorded in earnings at each reporting period through settlement. The fair value of the convertible notes was determined using a probability-weighted income approach as the convertible notes contained various settlement outcomes. The significant assumptions used to estimate the fair value of the convertible notes involved inherent uncertainties and the application of significant judgment, and included the time to maturity and the probability of the various settlement outcomes.

Revenue from Contracts

We recognize revenue from contracts when our customer obtains control of the promised goods or services, in an amount that reflects the consideration which we have received or expect to receive in exchange for those goods or services.

Our revenues are primarily derived through our collaborative research, development and license agreements. The terms of these types of agreements may include (i) research and development services, (ii) licenses for our technology or programs, and (iii) services or obligations in connection with participation in research or steering committees. Payments to us under these arrangements typically include one or more of the following: nonrefundable upfront and license fees, research funding, milestone and other contingent payments for the achievement of defined research, development and commercial-based events, as well as royalties on sales of any commercialized products. We assess whether the promises in its arrangements with customers are considered distinct performance obligations that should be accounted for separately. Judgment may be required to determine whether the research and development services are distinct from the license to our intellectual property or participation on steering committees.

Arrangements that include rights to additional goods or services that are exercisable at a customer’s discretion are generally considered options. If these options provide a material right to the customer, they are considered performance obligations. The identification of material rights requires judgments related to the determination of the value of the underlying license relative to the option exercise price, including assumptions about technical feasibility and the probability of developing a candidate that would be subject to the option rights.

The transaction price in each arrangement is allocated based on the relative standalone selling price (“SSP”) of each distinct performance obligation, which requires judgment. In instances where SSP is not directly observable, such as when a license or service is not sold separately, SSP is determined using information that may include market conditions and other observable inputs. Due to the early stage of our licensed technology, the license of such technology is typically combined with research and development services and steering committee participation as one performance obligation. Changes in the key assumptions used to determine the SSP could have a significant effect on the allocation of arrangement consideration between multiple performance obligations.

Recently Issued Accounting Pronouncements

See Note 2 to our consolidated financial statements included elsewhere in this proxy statement/prospectus for recently issued accounting pronouncements.

Emerging Growth Company Status

The JOBS Act permits an emerging growth company to take advantage of an extended transition to comply with new or revised accounting standards applicable to public companies until those standards would otherwise apply to private companies. DYNS is an “emerging growth company” as defined in Section 2(a) of the Securities Act, and has elected to take advantage of the benefits of this extended transition period, which means that when an accounting standard is issued or revised and has different application dates for public or private companies, DYNS may adopt the new or revised standard only at the time private companies are required or permitted to adopt the new or revised standard.

Following the consummation of the Business Combination, we expect to remain an emerging growth company until the earlier of: (1) the last day of the fiscal year (a) following the fifth anniversary of the closing of the DYNS IPO (which occurred on May 25, 2021), (b) in which we have total annual revenue of at least $1.07 billion, or (c) in which we are deemed to be a large accelerated filer, which means the market value of our

307

Table of Contents

common equity that is held by

non-affiliates

exceeds $700 million as of the end of that fiscal year’s second fiscal quarter and our net sales for the year exceed $100 million; and (2) the date on which we have issued more than $1.0 billion in

non-convertible

debt securities during the preceding, rolling three-year period. As a result, following the Business Combination, our consolidated financial statements may not be comparable to the financial statements of companies that are required to comply with the effective dates for new or revised accounting standards that are applicable to public companies.

Segment Information

We have one business activity and operate in one reportable segment.

Quantitative and Qualitative Disclosures About Market Risk

We typically hold certain financial instruments for which a change in prevailing interest rates may cause the principal amount of the marketable securities to fluctuate. Financial instruments that potentially subject us to significant concentrations of credit risk consist primarily of cash, cash equivalents and short-term investments. We invest our excess cash primarily in money market funds, commercial paper and debt instruments of financial institutions, corporations, U.S. government-sponsored agencies and the U.S. Treasury. The primary objectives of our investment activities are to ensure liquidity and to preserve principal while at the same time maximizing the income we receive from our marketable securities without significantly increasing risk. Additionally, we established guidelines regarding approved investments and maturities of investments, which are designed to maintain safety and liquidity. For marketable investment securities with short-term maturities, we do not believe that an increase or decrease in market rates would have a significant impact on the realized values or the statements of operations and comprehensive loss. As such, we believe that if a 10.0% change in interest rates were to have occurred on September 30, 2021, this change would not have had a material effect on the fair value of our investment portfolio as of that date.

Substantially all of our cash is held with a single financial institution. Due to its size, this financial institution represents a minimal credit risk. While all of our cash and cash equivalents are held in money market funds which are not insured by the Federal Deposit Insurance Corporation, the Company has not experienced any losses in such accounts and based on current circumstances does not believe that it is exposed to significant credit risk.

Inflation generally affects us by increasing our cost of labor and research and development contract costs. We do not believe that inflation, interest rate changes, or exchange rate fluctuations has had a significant impact on our results of operations for any periods presented herein.

Narrative to the Summary Compensation Table

Senti’s compensation committee or board of directors reviews compensation annually for all employees, including named executive officers. In making compensation determinations, Senti considers compensation for comparable positions in the market, the historical compensation levels of executives, individual performance as compared to Senti’s expectations and objectives, Senti’s desire to motivate employees to achieve short- and long-term results that are in the best interests of Senti’s stockholders and a long-term commitment to the company.

Either the compensation committee or the board of directors has historically determined the executive officers’ compensation and has typically reviewed and discussed management’s proposed compensation with the chief executive officer for all executives other than the chief executive officer. Based on those discussions and its

310

Table of Contents

discretion, either Senti’s board of directors or compensation committee then approved the compensation of each executive officer. Upon the closing of the Business Combination, the compensation committee will determine the executive officers’ compensation and follow this process, but generally the compensation committee itself, rather than the board of directors, will approve the compensation of each executive officer.

Annual Base Salary

Base salaries for the executive officers are initially established through

arm’s-length

negotiations at the time of the executive officer’s hiring, taking into account such executive officer’s qualifications, experience, the scope of his or her responsibilities and competitive market compensation paid by other companies for similar positions within the industry and geography. Base salaries are reviewed periodically, typically in connection with Senti’s annual performance review process, and adjusted from time to time to realign salaries with market levels after taking into account individual responsibilities, performance and experience. In making decisions regarding salary increases, Senti may also draw upon the experience of members of the board of directors with executives at other companies. The 2021 base salaries for the named executive officers were as follows: (a) $475,000 for Dr. Lu; (b) $410,000 for Mr. Herberts; and (c) $400,000 for Dr. Lee.

Non-Equity

Incentive Plan Compensation

Senti’s named executive officers are each eligible to receive a discretionary annual bonus based on individual and company performance. In 2021, Dr. Lu was eligible to earn an annual target performance bonus equal to 50% of his 2021 base salary based on the achievement of corporate objectives. Mr. Herberts and Dr. Lee were eligible to earn an annual target performance bonus equal to 40% of their respective 2021 base salary based on the achievement of both individual and corporate objectives. Payment of 2021 annual bonuses was based in part on us achieving certain research and product development, capital raising and other target goals. The compensation committee determined that Dr. Lu, Mr. Herberts and Dr. Lee were entitled to approximately 92.3%, 92.3% and 100% respectively, of their target bonuses.

Equity-Based Incentive Awards

Senti’s equity-based incentive awards are designed to align our interests and those of Senti’s stockholders with those of Senti’s employees and consultants, including Senti’s named executive officers. As of December 31, 2021, stock option awards were the only form of equity award we granted to the named executive officers.

We have historically used stock options as incentives for long-term compensation to the named executive officers as the return on the awards is tied to an increase in our stock price. Senti may grant equity awards at such times as our board of directors or compensation committee determines appropriate in their discretion. Additional grants may occur periodically in order to incentivize executives with respect to achieving certain corporate goals or to reward them for exceptional performance.

Prior to the completion of the Business Combination, all of the equity incentive awards Senti granted were made pursuant to Senti’s 2016 Stock Incentive Plan, as amended, or the 2016 Plan. Following the completion of the Business Combination, Senti will grant equity incentive awards under the terms of our 2022 Equity Incentive Plan, or the 2022 Plan, which will become effective once the registration statement of which this proxy statement/prospectus forms a part is declared effective. The terms of Senti’s 2016 Plan are described below under “— Equity Benefit Plans.”

All stock options are granted with an exercise price per share that is no less than the fair market value of Senti’s common stock on the date of grant of such award. Senti’s stock option grants generally vest over a four-year period, and may be subject to acceleration of vesting and exercisability under certain termination and change in control events. See “— Outstanding Equity Awards at Fiscal

Year-End”

below for additional information.

Agreement with Philip Lee, Ph.D.

In December 2018, Senti entered into an employment letter agreement with Dr. Lee, Senti’s current Chief Technology Officer. Pursuant to his letter agreement, Dr. Lee held the position of Chief Operating Officer, and was initially entitled to an annual base salary of $350,000, a signing bonus of $126,666.67, and a discretionary annual target bonus equal to 35% of his base salary, contingent upon the achievement of performance objectives established by Senti. In January 2021, Dr. Lee’s annual base salary was increased to $400,000. Prior to his employment, starting in July 2016, Dr. Lee provided services to Senti pursuant to a consulting agreement. In connection with such consulting services, Dr. Lee was issued 3,750,000 shares of Senti common stock pursuant to a restricted stock purchase agreement, which vested as follows: 25% on the date of issuance and the remainder in 36 equal monthly installments thereafter, subject to Dr. Lee’s continued service through each such date.

Year-End”

above. Dr. Lee remains eligible for future equity awards as determined by the Combined Company’s board of directors or its compensation committee.

Potential Payments and Benefits upon Termination or Change in Control

Regardless of the manner in which a named executive officer’s employment with Senti terminates, the named executive officer is entitled to receive amounts earned during his term of service, including salary and accrued unused vacation pay.

Termination Payments and Benefits

Under the terms of their respective employment agreements, Dr. Lu, Mr. Herberts and Dr. Lee are each eligible to receive the following severance payments and benefits upon a termination without “cause” or upon “resignation for good reason,” each as defined below, contingent upon the named executive officer’s timely delivery to Senti of a satisfactory release of claims:

•

For Dr. Lu, he is entitled to a cash severance equal to 12 months of his then current base salary, plus the prorated portion of his target annual bonus, and up to 12 months of payment for continued group health plan benefits. If such termination or resignation occurs within 3 months before or 12 months after a change of control, then all of his then remaining unvested shares of restricted common stock will become fully vested, although such restricted stock has already vested in full.

Equity Benefit Plans

2016 Stock Incentive Plan

Senti’s board of directors adopted, and Senti’s stockholders approved the 2016 Stock Incentive Plan, or the 2016 Plan, in July 2016. As of December 31, 2021, under the 2016 Plan, options to purchase 57,732,604 shares of common stock were outstanding, and 3,648,364 shares of common stock remained available for future issuance.

Awards

. The 2016 Plan provides for the grant of ISOs to employees of Senti, any parent or certain subsidiary companies, and for the grant of NSOs and restricted shares to such employees, Senti’s directors, and to consultants engaged by Senti or any of its subsidiary companies.

Plan Administration

. Senti’s board of directors administers and interprets the provisions of the 2016 Plan. Senti’s board of directors may delegate any or all its powers under the 2016 Plan to a committee appointed by the Board (to the extent permitted under applicable law and regulations), except that the Board retains control to amend or terminate the plan and to determine share issuances pursuant to the terms of the 2016 Plan. Under the 2016 Plan, Senti’s board of directors (or a committee delegated by Senti’s board of directors) has the authority to construe terms of awards granted under the 2016 Plan and to prescribe, amend and rescind rules and regulations relating to the 2016 Plan, to determine the terms and provisions of awards granted under the 2016 Plan and to make all other determinations in the judgment of the Senti board of directors necessary or desirable for the administration of the 2016 Plan.

Stock Options and Restricted Shares.

Stock options and restricted shares granted under the 2016 Plan generally have terms similar to those described above with respect to stock options and restricted shares granted under the 2022 Plan, except the 2016 Plan provides that (unless otherwise provided for in a stock option agreement) stock options may be exercised for a period of 12 months in the case of an optionee’s death or permanent and total disability.

Changes to Capital Structure

. If, through or as a result of Senti’s merger, consolidation, sale of all or substantially all of our assets, reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar transaction, (i) the outstanding shares of common stock are increased, decreased or exchanged for a different number or kind of shares or other securities of Senti, or (ii) additional shares or new or different or other securities of Senti or other noncash assets are distributed with respect to such shares of Senti common stock or other securities, an appropriate and proportionate adjustment shall be made in (x) the maximum number and kind of shares reserved for issuance under the 2016 Plan, (y) the number and kind of shares or other securities subject to any then outstanding stock options, and (z) the price for each share or other security subject to any then outstanding stock options, and (z) the price for each share or other security subject to any then outstanding stock options, so that upon exercise of such stock options, in lieu of the share of common stock for which such options were then exercisable, the relevant optionee shall be entitled to receive, for the same aggregate consideration, the same total number and kind of shares or other securities, cash or property that the owner of an equal number of outstanding shares of common stock immediately prior to the event requiring adjustment would own as a result of the event.

Corporate Transactions

. If Senti is merged with or into or consolidated with another corporation under circumstances where Senti stockholders immediately prior to such merger or consolidation do not own after such merger or consolidation shares representing at least fifty percent (50%) of the voting power of Senti or the surviving or resulting corporation, as the case may be, or if shares representing fifty percent (50%) or more of the voting power of Senti are transferred to an unrelated third party, as hereinafter defined, or if Senti is liquidated, or sells or otherwise disposes of all or substantially all of its assets (each such transaction is referred to as a “change in control transaction”), Senti’s board of directors, or the board of directors of any corporation assuming the obligations of Senti, may, in its discretion, take any one or more of the following actions, as to some or all outstanding stock options or restricted stock awards (and need not take the same action as to each such option or

restricted stock award): (i) provide that such stock options shall be assumed, or equivalent stock options will be substituted, by the acquiring or succeeding corporation (or an affiliate thereof),

provided that

any such stock options substituted for incentive stock options shall meet the requirements of Section 424(a) of the Code, (ii) upon written notice to the optionees, provide that all unexercised stock options (whether vested or unvested) will terminate immediately prior to the consummation of the change in control transaction unless exercised by the optionee to the extent otherwise then exercisable within a specified period following the date of such notice, (iii) upon written notice to the grantees, provide that all unvested shares of restricted stock shall be repurchased at cost, (iv) make or provide for a cash payment to the optionees equal to the difference between (A) the fair market value of the per share consideration (whether cash, securities or other property or any combination of the above) the holder of a share of common stock will receive upon consummation of the change in control transaction (the “per share transaction price”) times the number of shares of common stock subject to outstanding vested stock options (to the extent then exercisable at prices not equal to or in excess of the per share transaction price) and (B) the aggregate exercise price of such outstanding vested stock options, in exchange for the termination of such stock options, or (v) provide that all or any outstanding stock options shall become exercisable and all or any outstanding restricted stock awards shall vest in part or in full immediately prior to such event. To the extent that any stock options are exercisable at a price equal to or in excess of the per share transaction price, the Senti board of directors may provide that such stock options shall terminate immediately upon the consummation of the change in control transaction without any payment being made to the holders of such stock options.

BENEFICIAL OWNERSHIP

The following table and accompanying footnotes set forth information regarding the (1) actual beneficial ownership of shares of DYNS Common Stock as the Record Date, and (2) expected beneficial ownership of shares of New Senti common stock immediately following the consummation of the Business Combination (assuming a “no redemption” scenario and assuming a “maximum redemption scenario” as described below) by:

•

DYNS’s current executive officers and directors;

•

each person who is expected to become one of the executive officers or directors of New Senti following the Business Combination, assuming the Director Election Proposal is approved;

•

all of DYNS’ current executive officers and directors as a group, and all of the executive officers and directors of New Senti, assuming the Director Election Proposal is approved, as a group; and

•

each person who is known to be the beneficial owner of more than 5% of the outstanding DYNS Common Stock or is expected to be the beneficial owner of more than 5% of shares of New Senti common stock following the Business Combination.

Beneficial ownership is determined in accordance with the rules and regulations of the SEC. A person is a “beneficial owner” of a security if that person has or shares “voting power,” which includes the power to vote or to direct the voting of the security, or “investment power,” which includes the power to dispose of or to direct the disposition of the security, or has the right to acquire such powers within 60 days.

The beneficial ownership of shares of DYNS Common Stock prior to the Business Combination is calculated based on 29,465,500 shares of DYNS Common Stock (consisting of 23,715,500 shares of Class A Common Stock and 5,750,000 shares of Class B Common Stock) issued and outstanding as of the Record Date. For purposes of the table below, voting power represents the combined voting power of Class A Common Stock and Class B Common Stock owned beneficially by such person and, on all matters to be voted upon, the holders of the Class A Common Stock and the Class B Common Stock vote together as a single class. Currently, all of the Class B Common Stock are convertible into Class A Common Stock on a one-for-one basis.

The expected beneficial ownership of shares of New Senti common stock following the Business Combination is calculated based on 58,858,614 shares (assuming no redemptions) of New Senti common stock expected to be outstanding immediately following consummation of the Business Combination and assumes an exchange ratio for converting each share of Senti preferred stock and/or Senti common stock into shares of New Senti common stock of 0.1938. Such expected number of shares of New Senti common stock outstanding amount includes shares that are expected to be issued in connection with the PIPE Investment.

The expected beneficial ownership of shares of New Senti common stock following the Business Combination also assumes two redemption scenarios as follows:

•

Assuming No Redemptions (Scenario 1)

•

Assuming Maximum Redemptions (Scenario 2)

318

Table of Contents

Class A Common Stock do not apply in circumstances where they are compelled to do so in connection with non-discretionary ETF or mutual fund pro rata rebalancing transfers. If one or more Anchor Investors was compelled to transfer shares of Class A Common Stock for this reason, it is possible that more than 14,308,345 Public Shares could be redeemed and that there may not be $150,000,000 in cash available at Closing. As this condition is for Senti’s benefit, it is possible that Senti could waive it prior to Closing, although there is no guarantee that it would. The redemption of more than 14,308,345 Public Shares would change some of the figures presented in the maximum redemptions scenario in the unaudited pro forma financial data which follows.

Unless otherwise noted in the footnotes to the following table, and subject to applicable community property laws, the persons and entities named in the table have sole voting and investment power with respect to their beneficially owned common stock.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

Policies and Procedures for Related Party Transactions

DYNS’s Code of Ethics requires DYNS to avoid, wherever possible, all conflicts of interests, except under guidelines or resolutions approved by the Board (or the appropriate committee of the Board) or as disclosed in DYNS’s public filings with the SEC. Under DYNS’s Code of Ethics, conflict of interest situations will include any financial transaction, arrangement or relationship (including any indebtedness or guarantee of indebtedness) involving the company. Additionally, DYNS’s related party transaction policy sets forth the policies and procedures for the review and approval or ratification of related party transactions. This policy covers any transaction, arrangement or relationship or any series of similar transactions, arrangements or relationships, in which DYNS is a participant and a related party had or will have a direct or indirect material interest, as determined by the audit committee of DYNS’s Board, including, without limitation, purchases of goods or services by or from the related party or entities in which the related party has a material interest, and indebtedness, guarantees of indebtedness or employment by DYNS of a related party. These procedures are intended to determine whether any such related party transaction impairs the independence of a director or presents a conflict of interest on the part of a director, employee or officer.

DYNS’s audit committee, pursuant to its written charter, is responsible for reviewing and approving related party transactions to the extent that DYNS enters into such transactions. An affirmative vote of a majority of the members of the audit committee present at a meeting at which a quorum is present is required in order to approve a related party transaction. A majority of the members of the entire audit committee constitute a quorum. Without a meeting, the unanimous written consent of all of the members of the audit committee is required to approve a related party transaction.

DYNS Related Party Transactions

Founder Shares

On March 8, 2021, the Sponsor was issued 5,750,000 shares of Class B common stock (the “Founder Shares”) for an aggregate price of $25,000. The Founder Shares included an aggregate of up to 750,000 shares of Class B common stock subject to forfeiture by the Sponsor to the extent that the underwriter’s over-allotment option was not exercised in full or in part, so that the Sponsor would own, on an as-converted basis, 20% of our issued and outstanding shares after our initial public offering (excluding the private placement shares (as defined below) and assuming our sponsor did not purchase any public shares in our initial public offering). The underwriter fully exercised the over-allotment option on May 28, 2021; thus, these 750,000 Founder Shares are no longer subject to forfeiture.

Private Placement

Simultaneously with the closing of our initial public offering, we consummated the sale of 715,500 shares of Class A common stock (the “private placement shares”) at a price of $10.00 per share in a private placement to our sponsor, generating gross proceeds of $7,155,000. A portion of the proceeds from the sale of the private placement shares was added to the net proceeds from our initial public offering held in the trust account. If we do not complete an initial business combination within 24 months from the closing of our initial public offering, the proceeds from the sale of the private placement shares held in the trust account will be used to fund the redemption of public shares (subject to the requirements of applicable law).

DESCRIPTION OF NEW SENTI’S SECURITIES AFTER THE BUSINESS COMBINATION

As a result of the Business Combination, DYNS stockholders who receive shares of Class A Common Stock will become the stockholders of the Combined Company. Your rights as the Combined Company stockholders will be governed by Delaware law and the Proposed Charter, if approved, and DYNS’s Bylaws. The following description of the material terms of the Combined Company’s securities reflects the anticipated state of affairs upon completion of the Business Combination.

In connection with the Business Combination, DYNS will amend and restate the Current Charter. The following summary of the material terms the Combined Company’s securities following the Business Combination is not intended to be a complete summary of the rights and preferences of such securities. The full text of the Proposed Charter is attached as Annex B to this proxy statement/prospectus. You are encouraged to read the applicable provisions of Delaware law, the Proposed Charter and the Bylaws in their entirety for a complete description of the rights and preferences of the Combined Company securities following the Business Combination.

Authorized and Outstanding Stock

The Proposed Charter authorizes the issuance of shares, consisting of shares of common stock, $0.0001 par value per share, and shares of preferred stock, $0.0001 par value. As of the Record Date, there were shares of Class A Common Stock and shares of Class B Common Stock outstanding. In connection with the Business Combination and subject to the terms of the Current Charter, all shares of outstanding Class B Common Stock will automatically be converted into shares of Class A Common Stock. No shares of preferred stock are currently outstanding.

Common Stock

The Proposed Charter, which DYNS will adopt if the Charter Amendment Proposal is approved, provides the following with respect to the rights, powers, preferences and privileges of the New Senti common stock.

Voting Power

Except as otherwise required by law or as otherwise provided in any certificate of designation for any series of preferred stock, the holders of New Senti common stock possess all voting power for the election of the Combined Company’s directors and all other matters requiring stockholder action. Holders of New Senti common stock are entitled to one vote per share on matters to be voted on by stockholders.

Dividends

Holders of New Senti common stock will be entitled to receive such dividends, if any, as may be declared from time to time by the Combined Company’s board of directors in its discretion out of funds legally available therefor. DYNS has not historically paid any cash dividends on its Class A Common Stock or Class B Common Stock to date and does not intend to pay cash dividends in the foreseeable future. Any payment of cash dividends in the future will be dependent upon New Senti’s revenues and earnings, if any, capital requirements and general financial conditions. In no event will any stock dividends or stock splits or combinations of stock be declared or made on New Senti common stock unless the shares of New Senti common stock at the time outstanding are treated equally and identically.

Liquidation, Dissolution and Winding Up

In the event of the Combined Company’s voluntary or involuntary liquidation, dissolution or

winding-up,

the net assets of New Senti will be distributed pro rata to the holders of New Senti common stock, subject to the rights of the holders of the preferred stock, if any.

328

Table of Contents

Preemptive or Other Rights

There are no sinking fund provisions applicable to the New Senti common stock.

Preferred Stock

The Proposed Charter provides that shares of preferred stock may be issued from time to time in one or more series. New Senti’s board of directors will be authorized to fix designations, powers, including voting powers, full or limited, or no voting powers, preferences and the relative, participating, optional or other special rights of the shares of each series of preferred stock and any qualifications, limitations and restrictions thereof. New Senti’s board of directors will be able to, without stockholder approval, issue preferred stock with voting and other rights that could adversely affect the voting power and other rights of the holders of the New Senti common stock and could have anti-takeover effects. The ability of New Senti’s board of directors to issue preferred stock without stockholder approval could have the effect of delaying, deferring or preventing a change of control of New Senti or the removal of existing management. DYNS has no preferred stock currently outstanding.

Registration Rights

DYNS, certain of the Senti stockholders and certain of the DYNS stockholders will enter into an Investor Rights Agreement, pursuant to which, among other things, such stockholders will be granted certain registration rights with respect to certain shares of securities held by them. A copy of the Investor Rights Agreement is attached as Exhibit 10.18 hereto and incorporated herein by reference.

Anti-Takeover Provisions

Proposed Charter and Bylaws

Among other things, the Proposed Charter and Bylaws (as amended from time to time) will:

•

permit the Combined Company’s board of directors to issue up to shares of preferred stock, with any rights, preferences and privileges as they may designate, including the right to approve an acquisition or other change of control;

•

provide that the number of directors of the Combined Company may be changed only by resolution of the Combined Company’s board of directors;

•

provide that, subject to the rights of any series of preferred stock to elect directors, directors may be removed only with cause by the holders of at least 75% of all of the Combined Company’s then-outstanding shares of the capital stock entitled to vote generally at an election of directors;

•

provide that all vacancies, subject to the rights of any series of preferred stock, including newly created directorships, may, except as otherwise required by law, be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum;

•

provide that stockholders seeking to present proposals before a meeting of stockholders or to nominate candidates for election as directors at a meeting of stockholders must provide advance notice in writing, and also specify requirements as to the form and content of a stockholder’s notice;

•

provide that Special Meetings of the Combined Company’s stockholders may be called the Combined Company’s board of directors pursuant to a resolution adopted by a majority of the board;

•

provide that the Combined Company’s board of directors will be divided into three classes of directors, with the directors serving three-year terms (see the section titled “

Management of the Combined Company

”), therefore making it more difficult for stockholders to change the composition of the board of directors; and

329

Table of Contents

•

not provide for cumulative voting rights, therefore allowing the holders of a majority of the shares of New Senti common stock entitled to vote in any election of directors to elect all of the directors standing for election, if they should so choose.

The combination of these provisions will make it more difficult for the existing stockholders to replace the Combined Company’s board of directors as well as for another party to obtain control of the Combined Company by replacing the Combined Company’s board of directors. Because the Combined Company’s board of directors will have the power to retain and discharge its officers, these provisions could also make it more difficult for existing stockholders or another party to effect a change in management. In addition, the authorization of undesignated preferred stock will make it possible for the Combined Company’s board of directors to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to change the control of the Combined Company.

These provisions are intended to enhance the likelihood of continued stability in the composition of the Combined Company’s board of directors and its policies and to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to reduce the Combined Company’s vulnerability to hostile takeovers and to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for the Combined Company’s shares and may have the effect of delaying changes in our control or management. As a consequence, these provisions may also inhibit fluctuations in the market price of the Combined Company’s stock.

Certain Anti-Takeover Provisions of Delaware Law

DYNS is currently subject to the provisions of Section 203 of the DGCL and the Combined Company will also be subject to these provisions. This statute prevents certain Delaware corporations, under certain circumstances, from engaging in a “business combination” with:

•

a stockholder who owns 15% or more of our outstanding voting stock (otherwise known as an “interested stockholder”);

•

an affiliate of an interested stockholder; or

•

an associate of an interested stockholder, for three years following the date that the stockholder became an interested stockholder.

A “business combination” includes a merger or sale of more than 10% of a corporation’s assets. However, the above provisions of Section 203 would not apply if:

•

the relevant board of directors approves the transaction that made the stockholder an “interested stockholder,” prior to the date of the transaction;

•

after the completion of the transaction that resulted in the stockholder becoming an interested stockholder, that stockholder owned at least 85% of the corporation’s voting stock outstanding at the time the transaction commenced, other than statutorily excluded shares of common stock; or

•

on or subsequent to the date of the transaction, the initial business combination is approved by the board of directors and authorized at a meeting of the corporation’s stockholders, and not by written consent, by an affirmative vote of at least

two-thirds

of the outstanding voting stock not owned by the interested stockholder.

These provisions may have the effect of delaying, deferring, or preventing changes in control of the Combined Company.

SECURITIES ACT RESTRICTIONS ON RESALE OF COMMON STOCK

Rule 144

Pursuant to Rule 144, a person who has beneficially owned restricted shares or warrants for at least six months would be entitled to sell their securities provided that (i) such person is not deemed to have been one of our affiliates at the time of, or at any time during the three months preceding, a sale and (ii) we are subject to the Exchange Act periodic reporting requirements for at least three months before the sale and have filed all required reports under Section 13 or 15(d) of the Exchange Act during the 12 months (or such shorter period as we were required to file reports) preceding the sale.

Persons who have beneficially owned restricted shares for at least six months but who are our affiliates at the time of, or at any time during the three months preceding, a sale, would be subject to additional restrictions, by which such person would be entitled to sell within any three-month period only a number of securities that does not exceed the greater of:

•

1% of the total number of ordinary shares then outstanding; or

•

the average weekly reported trading volume of the Class A ordinary shares during the four calendar weeks preceding the filing of a notice on Form 144 with respect to the sale.

Sales by our affiliates under Rule 144 are also limited by manner of sale provisions and notice requirements and to the availability of current public information about us.

Restrictions on the Use of Rule 144 by Shell Companies or Former Shell Companies

Rule 144 is not available for the resale of securities initially issued by shell companies (other than business combination related shell companies) or issuers that have been at any time previously a shell company. However, Rule 144 also includes an important exception to this prohibition if the following conditions are met:

•

the issuer of the securities that was formerly a shell company has ceased to be a shell company;

•

the issuer of the securities is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act;

•

the issuer of the securities has filed all Exchange Act reports and material required to be filed, as applicable, during the preceding 12 months (or such shorter period that the issuer was required to file such reports and materials), other than Current Reports on Form 8-K; and

•

at least one year has elapsed from the time that the issuer filed current Form 10 type information with the SEC reflecting its status as an entity that is not a shell company.

As a result, our initial shareholders will be able to sell their founder shares pursuant to Rule 144 without registration one year after we have completed our initial business combination.

The Nasdaq listing standards generally define an “independent director” as a person who is not an executive officer or employee, or who does not have a relationship which, in the opinion of the company’s board of directors, would interfere with the exercise of independent judgment in carrying out his or her responsibilities as a director.

A stockholder providing timely notice of nominations or business proposed to be brought before an annual meeting shall further update and supplement such notice, if necessary, so that the information (including, without limitation, the Material Ownership Interests information) provided or required to be provided in such notice pursuant to the proposed bylaws shall be true and correct as of the record date for the meeting and as of the date that is ten (10) business days prior to such annual meeting, and such update and supplement shall be received by the secretary at the principal executive offices of the corporation not later than the close of business on the fifth (5th) business day after the record date for the annual meeting (in the case of the update and supplement required to be made as of the record date), and not later than the close of business on the eighth (8th) business day prior to

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholder and Board of Directors of

Dynamics Special Purpose Corp.

Opinion on the Financial Statements

We have audited the accompanying balance sheet of Dynamics Special Purpose Corp. (the “Company”) as of March 8, 2021, the related statements of operations, changes in stockholder’s equity and cash flows for the period from March 1, 2021 (inception) through March 8, 2021, and the related notes

(collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of March 8, 2021, and the results of its operations and its cash flows for the period from March 1, 2021 (inception) through March 8, 2021, in conformity with accounting principles generally accepted in the United States of America.

xplanatory Paragraph

– Going Concern

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As more fully described in Note 1 to the financial statements, the Company’s business plan is dependent upon its completion of the proposed initial public offering described in Note 3 to the financial statements. The Company has a working capital deficiency as of March 8, 2021 and lacks the financial resources it needs to sustain operations for a reasonable period of time, which is considered to be one year from the issuance date of the financial statements. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans with regard to these matters are also described in Notes 1 and 3. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

Dynamics Special Purpose Corp.

Notes to financial statements

Note 1. Description of organization, business operations and going concern

Dynamics Special Purpose Corp. (the “Company”) is a blank check company incorporated in Delaware on March 1, 2021. The Company was formed for the purpose of entering into a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (a “Business Combination”). The Company is not limited to a particular industry or geographic region for purposes of consummating a Business Combination. The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies.

As of March 8, 2021, the Company had not commenced any operations. All activity for the period from March 1, 2021 (inception) through March 8, 2021 relates to the Company’s formation and the proposed initial public offering (“Proposed Public Offering”), which is described below. The Company will not generate any operating revenues until after the completion of a Business Combination, at the earliest. The Company will generate

non-operating

income in the form of interest income from the proceeds derived from the Proposed Public Offering. The Company has selected December 31 as its fiscal year end.

The Company’s ability to commence operations is contingent upon obtaining adequate financial resources through a Proposed Public Offering of 20,000,000 shares of Class A common stock (the “Public Shares”) at $10.00 per share (or 23,000,000 shares if the underwriter’s over-allotment option is exercised in full), which is discussed in Note 3, and the sale of 655,500 shares of Class A common stock (or 715,500 shares of Class A common stock if the underwriter’s over-allotment option is exercised in full) (the “Private Placement Shares”), at a price of $10.00 per Private Placement Share, in a private placement to Dynamics Sponsor LLC (the “Sponsor”), that will close simultaneously with the Proposed Public Offering.

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Proposed Public Offering and the sale of the Private Placement Shares, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company must complete a Business Combination with one or more target businesses that together have an aggregate fair market value of at least 80% of the value of the Trust Account (as defined below) (excluding the deferred underwriting commissions and taxes payable on income earned on the Trust Account) at the time of the agreement to enter into an initial Business Combination. The Company will only complete a Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”). Upon the closing of the Proposed Public Offering, management has agreed that an amount equal to at least $10.00 per Public Share sold in the Proposed Public Offering, including the proceeds from the sale of the Private Placement Shares, will be held in a trust account (“Trust Account”), located in the United States and invested only in U.S. government securities with a maturity of 185 days or less or in money market funds meeting certain conditions under Rule

2a-7

under the Investment Company Act which invest only in direct U.S. government treasury obligations, as determined by the Company, until the earlier of: (i) the completion of a Business Combination and (ii) the distribution of the funds held in the Trust Account, as described below.

stockholders will be entitled to redeem their shares for a pro rata portion of the amount held in the Trust Account (initially

anticipated to be $10.00 per share), calculated as of two business days prior to the completion of a Business Combination, including any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations. The shares of Class A common stock will be recorded at redemption value and classified as temporary equity upon the completion of the Proposed Public Offering, in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 480,

Distinguishing Liabilities from Equity

The Company will proceed with a Business Combination if the Company has net tangible assets of at least $5,000,001 upon consummation of such Business Combination and a majority of the shares voted are voted in favor of the Business Combination. If a stockholder vote is not required under applicable law or stock exchange listing requirements and the Company does not decide to hold a stockholder vote for business or other reasons, the Company will, pursuant to its amended and restated certificate of incorporation (the “Amended and Restated Certificate of Incorporation”), conduct the redemptions pursuant to the tender offer rules of the Securities and Exchange Commission (“SEC”), and file tender offer documents with the SEC prior to completing a Business Combination. If the Company seeks stockholder approval in connection with a Business Combination, the holders of the Founder Shares (as defined in Note 5) have agreed to vote their Founder Shares and any Public Shares purchased in or after the Proposed Public Offering in favor of approving a Business Combination and to waive their redemption rights with respect to any such shares in connection with a stockholder vote to approve a Business Combination. Additionally, each public stockholder may elect to redeem their public shares without voting, and if they do vote, irrespective of whether they vote for or against the proposed Business Combination.

Notwithstanding the foregoing, if the Company seeks stockholder approval of a Business Combination and it does not conduct redemptions pursuant to the tender offer rules, the Company’s Amended and Restated Certificate of Incorporation provides that a public stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% of the Public Shares without the Company’s prior written consent.

The initial stockholders have agreed to waive (a) their redemption rights with respect to any Founder Shares and Public Shares they hold in connection with the completion of an initial Business Combination, (b) their redemption rights with respect to any Founder Shares, Private Placement Shares and Public Shares they hold in connection with a stockholder vote to approve an amendment to the Amended and Restated Certificate of Incorporation to modify the substance or timing of the Company’s obligation to allow redemption in connection with an initial Business Combination or to redeem 100% of the Public Shares if the Company has not consummated an initial Business Combination within 24 months from the closing of the Proposed Public Offering or with respect to any other provisions relating to stockholders’ rights or

pre-initial

Business Combination activity and (c) their rights to liquidating distributions from the Trust Account with respect to any Founder Shares and Private Placement Shares they hold if the Company fails to complete an initial Business Combination within 24 months from the closing of the Proposed Public Offering. However, if the initial stockholders acquire Public Shares in or after the Proposed Public Offering, such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a Business Combination within the Combination Period (as defined below).

The Company will have until 24 months from the closing of the Proposed Public Offering (the “Combination Period”) to complete a Business Combination. If the Company is unable to complete a Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but no more than ten business days thereafter subject to

lawfully available funds therefor, redeem the Public Shares at a per-share price, payable in cash, equal to the aggregate amount then on

deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its franchise and income taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining stockholders and board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

The underwriter has agreed to waive its rights to its deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a Business Combination within in the Combination Period and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than the Proposed Public Offering price per Public Share ($10.00).

In order to protect the amounts in the Trust Account, the Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below (i) $10.00 per Public Share or (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per Public Share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under the Company’s indemnity of the underwriter of the Proposed Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (other than the Company’s independent registered accounting firm), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.

Going concern consideration

At March 8, 2021 the Company had no cash and a working capital deficit of $150,279. Further, the Company expects to continue to incur significant costs in pursuit of its financing and acquisition plans. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. Management plans to address this uncertainty through the Proposed Public Offering. There is no assurance that the Company’s plans to raise capital will be successful. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Risks and uncertainties

Management continues to evaluate the impact of the

COVID-19

pandemic on the healthcare industry and the life sciences subsector in which it seeks to consummate a Business Combination and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company’s financial position, results

of its operations, close of the Proposed Public Offering, and/or search for a target company, the specific impact is not readily determinable as of the date of these financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Note 2. Summary of significant accounting policies

Basis of presentation

The accompanying financial statements are presented in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the SEC.

Emerging growth company

The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.

Further, section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to

non-emerging

growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Use of estimates

The preparation of financial statements in conformity with U.S. GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period.

Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ from those estimates.

F-10

Dynamics Special Purpose Corp.

Notes to financial statements

Cash and cash equivalents

The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company did not have any cash equivalents as of March 8, 2021.

Deferred offering costs

Deferred offering costs consist of legal, accounting, underwriting fees and other costs incurred through the balance sheet date that are directly related to a planned public offering and that will be charged to stockholder’s equity upon the completion of a planned public offering. Should a planned public offering prove to be unsuccessful, these deferred costs, as well as additional expenses to be incurred, will be charged to operations.

Income taxes

The Company follows the asset and liability method of accounting for income taxes under ASC Topic 740,

Income Taxes

. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.

ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of March 8, 2021. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception.

The provision for income taxes was deemed to be de minimis for the period from March 1, 2021 (inception) through March 8, 2021.

Net loss per common share

Net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Weighted average shares were reduced for the effect of an aggregate of 750,000 shares of common stock that are subject to forfeiture if the over-allotment option is not exercised by the underwriter (see Note 6). At March 8, 2021, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into shares of common stock and then share in the earnings of the Company. As a result, diluted loss per share is the same as basic loss per share for the period presented.

Fair value of financial instruments

The fair value of the Company’s assets and liabilities, which qualify as financial instruments under FASB ASC Topic 820,

Fair Value Measurement

, approximates the carrying amounts represented in the accompanying balance sheet, primarily due to their short-term nature.

Notes to financial statements

Recent accounting standards

Management does not believe that any recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s financial statements.

Note 3. Proposed public offering

Pursuant to the Proposed Public Offering, the Company will offer for sale 20,000,000 shares of Class A common stock (or 23,000,000 shares of Class A common stock if the underwriter’s over-allotment option is exercised in full) at a purchase price of $10.00 per share.

Note 4. Private placement

The Sponsor has agreed to purchase an aggregate of 655,500 Private Placement Shares (or 715,500 Private Placement Shares if the underwriter’s over-allotment option is exercised in full) at a price of $10.00 per Private Placement Share, from the Company in a private placement that will occur simultaneously with the closing of the Proposed Public Offering. A portion of the proceeds from the sale of the Private Placement Shares will be added to the net proceeds from the Proposed Public Offering held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the proceeds from the sale of the Private Placement Shares held in the Trust Account will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law) .

Note 5. Related party transactions

Founder shares

On March 8, 2021, the Sponsor was issued 5,750,000 shares (the “Founder Shares”) of Class B common stock for an aggregate price of $25,000. The Founder Shares include an aggregate of up to 750,000 shares of Class B common stock subject to forfeiture by the Sponsor to the extent that the underwriter’s over-allotment option is not exercised in full or in part, so that the Sponsor will own, on an

as-converted

basis, 20% of the Company’s issued and outstanding shares after the Proposed Public Offering (excluding the private placement shares) (assuming the Sponsor does not purchase any Public Shares in the Proposed Public Offering).

Promissory note—related party

On March 8, 2021, the Sponsor agreed to loan the Company an aggregate of up to $300,000 to cover expenses related to the Proposed Public Offering pursuant to an unsecured promissory note (the “Promissory Note”). This loan is non-interest bearing and payable on the earlier of (i) December 31, 2021 or (ii) the consummation of the Proposed Public Offering. As of March 8, 2021, there were no borrowings outstanding under the Promissory Note.

Related party loans

in the Trust Account would be used to repay the Working Capital Loans. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans.

Up to $2,000,000 of such Working Capital Loans may be convertible into shares at a price of $10.00 per share at the option of the lender. The share would be identical to the Private Placement Shares.

Note 6. Commitments

Registration and stockholder rights agreement

The holders of the Founder Shares, Private Placement Shares and any Class A common stock issuable upon conversion of the Working Capital Loans will be entitled to registration rights pursuant to a registration and stockholder rights agreement to be signed prior to or on the effective date of the Proposed Public Offering. The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company register such securities. In addition, the holders will have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the completion of an initial Business Combination. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriting agreement

The Company will grant the underwriter a

45-day

option from the date of the Proposed Public Offering to purchase up to 3,000,000 additional shares of Class A common stock to cover over-allotments, if any, at the Proposed Public Offering price less the underwriting discounts and commissions.

The underwriter will be entitled to a cash underwriting discount of $0.20 per share, or $4,000,000 in the aggregate (or $4,600,000 in the aggregate if the underwriter’s over-allotment option is exercised in full), payable upon the closing of the Proposed Public Offering. In addition, the underwriter will be entitled to a deferred fee of $0.35 per share, or $7,000,000 in the aggregate (or $8,050,000 in the aggregate if the underwriter’s over-allotment option is exercised in full). The deferred fee will become payable to the underwriter from the amounts held in the Trust Account solely in the event that the Company completes a Business Combination, subject to the terms of the underwriting agreement.

Note 7. Stockholder’s equity

Preferred stock

As of March 8, 2021, the Company had no authorized, issued, or outstanding shares of preferred stock. The Company intends to file an amended and restated Certificate of Incorporation prior to the closing date of the Proposed Public Offering such that the Company will be authorized to issue 1,000,000 shares of preferred stock with a par value of $0.0001 per share, with such designations, voting and other rights and preferences as may be determined from time to time by the Company’s board of directors.

Class A common stock

The Company is authorized to issue 100,000,000 shares of Class A common stock with a par value of $0.0001 per share. As of March 8, 2021, there were no shares of Class A common stock issued or outstanding.

Class B common stock

The Company is authorized to issue 10,000,000 shares of Class B common stock with a par value of $0.0001 per share. As of March 8, 2021, there were 5,750,000 shares of Class B common stock outstanding. Of the 5,750,000

F-13

Table of Contents

Dynamics Special Purpose Corp.

Notes to financial statements

shares of Class B common stock outstanding, up to 750,000 shares are subject to forfeiture to the Company by the Sponsor for no consideration to the extent that the underwriter’s over-allotment option is not exercised in full or in part, so that the initial stockholders will collectively own 20% of the Company’s issued and outstanding common stock after the Proposed Public Offering (excluding the private placement shares).

Common stockholders of record are entitled to one vote for each share held on all matters to be voted on by stockholders. Holders of the Class A common stock and holders of the Class B common stock will vote together as a single class on all matters submitted to a vote of stockholders, including any vote in connection with an initial Business Combination.

The shares of Class B common stock will automatically convert into shares of Class A common stock at the time of an initial Business Combination on a

one-for-one

basis (subject to adjustment for stock splits, stock dividends, reorganizations, recapitalizations and the like), and subject to further adjustment. In the case that additional shares of Class A common stock, or equity-linked securities, are issued or deemed issued in excess of the amounts offered in the Proposed Public Offering and related to the closing of an initial Business Combination, the ratio at which shares of Class B common stock shall convert into shares of Class A common stock will be adjusted (unless the holders of a majority of the outstanding shares of Class B common stock agree to waive such adjustment with respect to any such issuance or deemed issuance) so that the number of shares of Class A common stock issuable upon conversion of all shares of Class B common stock will equal, in the aggregate, on an

as-converted

basis, 20% of the sum of (i) the total number of all shares of common stock outstanding upon the completion of the Proposed Public Offering (excluding the private placement shares), plus (ii) all shares of Class A common stock and equity-linked securities issued or deemed issued in connection with an initial Business Combination (excluding any shares of Class A common stock or equity-linked securities issued, or to be issued, to any seller in an initial Business Combination and any Private Placement Shares issued to the Sponsor or its affiliates upon conversion of Working Capital Loans).

Note 8. Subsequent events

The Company evaluated subsequent events and transactions that occurred after the balance sheet date up to the date that the financial statements were issued. Based on this review, other than as described below, the Company did not identify any subsequent events that would have required adjustment or disclosure in the financial statements. In April 2021, the Company borrowed $250,000 under the Promissory Note.

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

SEPTEMBER 30, 2021

(AS RESTATED)

NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS

Dynamics Special Purpose Corp. (the “Company”) is a blank check company incorporated in Delaware on March 1, 2021. The Company was formed for the purpose of entering into a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities (a “Business Combination”). The Company is not limited to a particular industry or geographic region for purposes of consummating a Business Combination. The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies.

As of September 30, 2021, the Company had not commenced any operations. All activity for the period from March 1, 2021 (inception) through September 30, 2021 relates to the Company’s formation, the initial public offering (“Initial Public Offering”), which is described below, and identifying a target company for a Business Combination. The Company will not generate any operating revenues until after the completion of a Business Combination, at the earliest. The Company will generate

non-operating

income in the form of interest income from the proceeds derived from the Initial Public Offering. The Company has selected December 31 as its fiscal year end.

The registration statement for the Company’s Initial Public Offering was declared effective on May 25, 2021. On May 28, 2021, the Company consummated the Initial Public Offering of 23,000,000 shares of Class A common stock (the “Public Shares”), including 3,000,000 shares of Class A common stock that were issued pursuant to the underwriter’s exercise of their over-allotment option in full, at $10.00 per Public Share, generating gross proceeds of $230,000,000, which is discussed in Note

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 715,500 shares of Class A common stock (the “Private Placement Shares”) at a price of $10.00 per Private Placement Share in a private placement to Dynamics Sponsor LLC (the “Sponsor”), generating gross proceeds of $7,155,000, which is described in Note

Transaction costs amounted to $13,198,430 consisting of $4,600,000 of underwriting fees, $8,050,000 of deferred underwriting fees, and $548,430 of other offering costs.

Following the closing of the Initial Public Offering on May 28, 2021, an amount of $230,000,000 ($10.00 per Public Share) from the net proceeds of the sale of the Public Shares in the Initial Public Offering and the sale of the Private Placement Shares was placed in a trust account (the “Trust Account”), and will be invested only in U.S. government securities with maturities of 185 days or less or in money market funds meeting certain conditions under Rule

2a-7

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Shares, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company mus

The Company will only complete a Business Combination if the post-transaction company owns or

acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”).

The Company will provide its stockholders with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion, subject to applicable law and stock exchange listing requirements. The stockholders will be entitled to redeem their shares for a pro rata portion of the amount held in the Trust Account (initially anticipated to be $10.00 per share), calculated as of two business days prior to the completion of a Business Combination, including any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations.

Additionally, each public stockholder may elect to redeem their Public Shares without voting, and if they do vote, irrespective of whether they vote for or against the proposed Business Combination.

The initial stockholders have agreed to waive (a) their redemption rights with

such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a Business Combination within the Combination Period (as defined below).

The Company will have until May 28, 2023 to complete a Business Combination (the “Combination Period”). If the Company is unable to complete a Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but no more than ten business days thereafter subject to lawfully available funds therefor, redeem the Public Shares at a

price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its franchise and income taxes (less up to

$100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining stockholders and board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

The underwriter has agreed to waive its rights to its deferred underwriting commission (see Note

) held in the Trust Account in the event the Company does not complete a Business Combination within in the Combination Period and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than the Initial Public Offering price per Public Share ($10.00).

In order to protect the amounts in the Trust Account, the Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below (i) $10.00 per Public Share or (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per Public Share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under the Company’s indemnity of the underwriter of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (other than the Company’s independent registered accounting firm), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.

Liquidity

As of September 30, 2021, the Company had $984,544 in cash held outside of the Trust Account and working capital of 1,528,721.

The Company’s liquidity needs prior to the consummation of the Initial Public Offering were satisfied through the proceeds of $25,000 from the sale of the Founder Shares, and a loan of up to $300,000 under an unsecured and

non-interest

bearing promissory note (see Note

Class A Common Stock Subject to Possible Redemption

All of the 23,000,000 shares of Class A common stock sold as part of the Units in the Initial Public Offering contain a redemption feature which allows for the redemption of such Public Shares in connection with the Company’s liquidation, if there is a stockholder vote or tender offer in connection with the Business Combination and in connection with certain amendments to the Company’s second amended and restated certificate of incorporation. In accordance with SEC and its staff’s guidance on redeemable equity instruments, which has been codified in Accounting Standards Codification (“ASC”)

redemption provisions not solely within the control of the Company require common stock subject to redemption to be classified outside of permanent equity. Therefore, all

Income Taxes

The Company follows the asset and liability method of accounting for income taxes under ASC 740,

Income Taxes

(“ASC 740”). Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.

unrecognized tax benefits and

amounts accrued for interest and penalties as of September 30, 2021. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception

The provision for income taxes was deemed to be de minimis for the period from March 1, 2021 (inception) through September 30, 2021.

Net Loss Per Share of Common Stock

Net loss per common share is computed by dividing net loss by the we

ighted-a

verage number of shares of common stock outstanding during the period. As the Public Shares are considered to be redeemable at fair value, and a redemption at fair value does not amount to a distribution different than other stockholders, Class A and Class B common stock are presented as one class of stock in calculating net loss per share. As a result, the calculated net loss per share is the same for Class A and Class B shares of common stock. As of September 30, 2021, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into shares of common stock and then share in the earnings of the Company. As a result, diluted loss per share is the same as basic loss per share for the periods presented.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk co

nsist of a

cash account in a financial institution, which, at times, may exceed the Federal Depository Insurance Coverage of $250,000. The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account.

Fair Value of Financial Instruments

The Company applies ASC Topic 820,

Fair Value Measurement

(“ASC 820”), which establishes a framework for measuring fair value and clarifies the definition of fair value within that framework. ASC 820 defines fair value as an exit price, which is the price that would be received for an asset or paid to transfer a liability in the Company’s principal or most advantageous market in an orderly transaction between market participants on the measurement date. The fair value hierarchy established in ASC 820 generally requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs reflect the assumptions that market participants would use in pricing the asset or liability and are developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the entity’s own assumptions based on market data and the entity’s judgments about the assumptions that market participants would use in pricing the asset or liability and are to be developed based on the best information available in the circumstances.

The carrying amounts reflected in the balance sheet for current assets and current liabilities approximate fair value due to their short-term nature.

Level 1 — Assets and liabilities with unadjusted, quoted prices listed on active market exchanges. Inputs to the fair value measurement are observable inputs, such as quoted prices in active markets for identical assets or liabilities.

Level 2 — Inputs to the fair value measurement are determined using prices for recently traded assets and liabilities with similar underlying terms, as well as direct or indirect observable inputs, such as interest rates and yield curves that are observable at commonly quoted intervals.

F-26

Table of Contents

DYNAMICS SPECIAL PURPOSE CORP.

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

SEPTEMBER 30, 2021

(AS RESTATED)

Level 3 — Inputs to the fair value measurement are unobservable inputs, such as estimates, assumptions, and valuation techniques when little or no market data exists for the assets or liabilities.

See Note 8 for additional information on assets and liabilities measured at fair value.

Recent Accounting Standards

In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-06,

Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40)

(“ASU 2020-06”)

to simplify accounting for certain financial instruments. ASU 2020-06 eliminates the current models that require separation of beneficial conversion and cash conversion features from convertible instruments and simplifies the derivative scope exception guidance pertaining to equity classification of contracts in an entity’s own equity. The new standard also introduces additional disclosures for convertible debt and freestanding instruments that are indexed to and settled in an entity’s own equity. ASU 2020-06 amends the diluted earnings per share guidance, including the requirement to use the if-converted method for all convertible instruments. ASU 2020-06 is effective January 1, 2022 and should be applied on a full or modified retrospective basis, with early adoption permitted beginning on January 1, 2021. The Company is currently assessing the impact, if any, that ASU 2020-06 would have on its financial position, results of operations or cash flows.

Management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s financial statements.

NOTE

. INITIAL PUBLIC OFFERING

The registration statement for the Company’s Initial Public Offering was declared effective on May 25, 2021. On May 28, 2021, the Company completed its Initial Public Offering of 23,000,000 shares of Class A common stock, including 3,000,000 shares of Class A common stock that were issued pursuant to the underwriter’s exercise of its over-allotment option in full, at $10.00 per Public Share, generating gross proceeds of $230,000,000.

NOTE

. PRIVATE PLACEMENT

Simultaneously with the closing of the Initial Public Offering, the Sponsor purchased an aggregate of 715,500 Private Placement Shares at a price of $10.00 per Private Placement Share, generating gross proceeds of $7,155,000. A portion of the proceeds from the sale of the Private Placement Shares has been added to the net proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the proceeds from the sale of the Private Placement Shares held in the Trust Account will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law).

NOTE

. RELATED PARTY TRANSACTIONS

Founder Shares

On March 8, 2021, the Sponsor was issued 5,750,000 shares (the “Founder Shares”) of Class B common stock for an aggregate price of $25,000. The Founder Shares included an aggregate of up to 750,000 shares of Class B

common stock subject to forfeiture by the Sponsor to the extent that the underwriter’s over-allotment option was not exercised in full or in part, so that the Sponsor would own, on an

as-converted

basis, 20% of the Company’s issued and outstanding shares after the Initial Public Offering (excluding the Private Placement Shares) (assuming the Sponsor does not purchase any Public Shares in the Initial Public Offering). The underwriter fully exercised the over-allotment option on May 28, 2021; thus, these 750,000 Founder Shares are no longer subject to forfeiture.

Related Party Loans

In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes a Business Combination, the Company would repay the Working Capital Loans out of the proceeds held in the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a Business Combination is not completed, the Company may use a portion of the proceeds held outside the Trust Account to repay the Working Capital Loans but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. Up to $2,000,000 of such Working Capital Loans may be convertible into shares at a price of $10.00 per share at the option of the lender. The shares would be identical to the Private Placement Shares.

Administrative Support Agreement

The Company entered into an agreement, commencing on the effective date of the Initial Public Offering, to pay the Sponsor up to a total of $10,000 per month for office space, administrative and support services. Upon the completion of an initial Business Combination, the Company will cease paying these monthly fees. To date, the Company has not exercised its option to use such services.

The Company is authorized to issue 1,000,000 shares of preferred stock with a par value of $0.0001 per share with such designations, voting and other rights and preferences as may be determined from time to time by the Company’s board of directors. As of September 30, 2021, there were no shares of preferred stock issued or outstanding.

Class A common stock

—

The Company is authorized to issue 100,000,000 shares of Class A common stock with a par value of $0.0001 per share. Holders of Class A common stock are entitled to one vote for each share. As of September 30, 2021, there were 23,715,500 shares of Class A common stock issued and outstanding, including 23,000,000 shares of Class A common stock subject to possible redemption.

Class B common stock

—

The Company is authorized to issue 10,000,000 shares of Class B common stock with a par value of $0.0001 per share. Holders of Class B common stock are entitled to one vote for each share. As of September 30, 2021, there were 5,750,000 shares of Class B common stock issued and outstanding. Of the 5,750,000 shares of Class B common stock outstanding, up to 750,000 shares were subject to forfeiture to the Company by the Sponsor for no consideration to the extent that the underwriter’s over-allotment option was not exercised in full or in part, so that the initial stockholders would collectively own 20% of the Company’s issued

and outstanding common stock after the Initial Public Offering (excluding the Private Placement Shares). The over-allotment option was exercised in full on May 28, 2021; thus, these shares are no longer subject to forfeiture.

The shares of Class B common stock will automatically convert into shares of Class A common stock at the time of an initial Business Combination on a

one-for-one

basis (subject to adjustment for stock splits, stock dividends, reorganizations, recapitalizations and the like), and subject to further adjustment. In the case that additional shares of Class A common stock, or equity-linked securities, are issued or deemed issued in excess of the amounts offered in the Initial Public Offering and related to the closing of an initial Business Combination, the ratio at which shares of Class B common stock shall convert into shares of Class A common stock will be adjusted (unless the holders of a majority of the outstanding shares of Class B common stock agree to waive such adjustment with respect to any such issuance or deemed issuance) so that the number of shares of Class A common stock issuable upon conversion of all shares of Class B common stock will equal, in the aggregate, on an

as-converted

basis, 20% of the sum of (i) the total number of all shares of common stock outstanding upon the completion of the Initial Public Offering (excluding the Private Placement Shares), plus (ii) all shares of Class A common stock and equity-linked securities issued or deemed issued in connection with an initial Business

Senti Biosciences, Inc.:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Senti Biosciences, Inc. and subsidiary (the Company) as of December 31, 2019 and 2020, the related consolidated statements of operations and comprehensive loss, redeemable convertible preferred stock and stockholders’ deficit, and cash flows for each of the years in the

two-year

period ended December 31, 2020, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2019 and 2020, and the results of its operations and its cash flows for each of the years in the

two-year

period ended December 31, 2020, in conformity with U.S. generally accepted accounting principles.

Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has suffered recurring losses from operations and has an accumulated deficit, which raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB and in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Notes to Consolidated Financial Statements

1. Organization and Description of Business

Senti Biosciences, Inc. or (the “Company”), was incorporated under the laws of the State of Delaware in June 2016, and is a biotechnology company that programs next-generation cell and gene therapies with what we refer to as “gene circuits.” The Company is headquartered in South San Francisco, California.

Liquidity and Going Concern

The Company has devoted substantially all of its efforts to organizing and staffing, business planning, raising capital, and conducting preclinical studies and has not realized substantial revenues from its planned principal operations. In addition, the Company has a limited operating history, has incurred recurring operating losses and negative cash flows from operations since inception, has funded its operations primarily with proceeds from sale of redeemable convertible preferred stock and the issuance of convertible notes, and expects that it will continue to incur net losses and negative cash flows from operations into the foreseeable future, particularly as the Company advances its preclinical activities and clinical trials for its product candidates in development.

The Company’s continued existence is dependent upon management’s ability to develop profitable operations. Management is devoting substantially all of its efforts to developing its business and raising capital and there can be no assurance that the Company’s efforts will be successful. No assurance can be given that management’s actions will result in profitable operations or the meeting of ongoing liquidity needs.

The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. In 2020, the Company received aggregate proceeds of $30.0 million (Note 6) from the issuance of its Series B redeemable convertible preferred stock and of $8.0 million from the issuance of promissory notes (Note 5). In the nine months ended September 30, 2021 (unaudited), the Company received aggregate proceeds of $67.0 million (Note 6) from the issuance of its Series B redeemable convertible preferred stock. As of September 30, 2021 (unaudited), the Company had an accumulated deficit of $104.2 million, and cash, cash equivalents and restricted cash of $75.2 million. As of December 31, 2020, the Company had an accumulated deficit of $59.8 million, and cash, cash equivalents and restricted cash of $31.0 million.

As of April 12, 2021, the issuance date of the consolidated financial statements as of and for the year ended December 31, 2020, the Company has indicated that it expects that its cash and cash equivalents will not be sufficient to fund its operating expenses and capital expenditure requirements for at least one year from the date of the issuance of the audited consolidated financial statements and therefore the Company concluded that substantial doubt existed about the Company’s ability to continue as a going concern. As of February 14, 2022 (unaudited), the issuance date of the consolidated financial statements as of and for the nine months ended September 30, 2021 (unaudited), the Company expects that its cash and cash equivalents will not be sufficient to fund its operating expenses and capital expenditure requirements for at least one year from the issuance date of the consolidated financial statements.

The Company is seeking to complete a liquidity event via a special purpose acquisition company (“SPAC”) (Note 15). Upon the completion of a qualified public offering on specified terms (Note 6), the Company’s outstanding convertible preferred stock will automatically convert into shares of common stock. These plans are intended to mitigate the relevant conditions or events that raise substantial doubt about the Company’s ability to continue as a going concern; however, as the plans are not entirely within the Company’s control, management cannot assure they will be effectively implemented. In the event the Company does not complete a SPAC merger, the Company expects to seek additional funding through private equity financings, debt financings,

F-37

Table of Contents

collaborations, licensing arrangements, and/or strategic alliances. The Company may not be able to obtain financing on acceptable terms, or at all, and the Company may not be able to enter into collaborations or other such arrangements. The terms of any financing may adversely affect the holdings or the rights of the Company’s stockholders. If the Company is unable to raise capital when needed, or on attractive terms, it could be forced to delay, reduce or eliminate its research or drug development programs or any future commercialization efforts (unaudited).

2. Summary of Significant Accounting Policies and Basis of Presentation

Basis of Preparation

The accompanying consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”). Any reference in these notes to applicable guidance is meant to refer to the authoritative U.S. GAAP as found in the Accounting Standards Codification (“ASC”) and as amended by Accounting Standards Updates (“ASU”) of the Financial Accounting Standards Board (“FASB”). The consolidated financial statements include the accounts of Senti Biosciences, Inc., and its wholly-owned subsidiary. All intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates, judgments, and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates and assumptions reflected in these consolidated financial statements include, but are not limited to, the accrual for research and development expenses, the valuation of stock-based awards, the valuation of convertible notes, the valuation of common and redeemable convertible preferred stock, the valuation of preferred stock tranche liability, standalone selling price (“SSP”) and the determination of the incremental borrowing rate. Actual results could differ from those estimates, and such differences could be material to the financial position and consolidated statements of operations and comprehensive loss.

Unaudited Interim Financial Information

The accompanying consolidated balance sheet as of September 30, 2021, the consolidated statements of operations and comprehensive loss, redeemable convertible preferred stock and stockholders’ deficit, and cash flows for the nine months ended September 30, 2021 and 2020, are unaudited. The unaudited consolidated financial statements have been prepared on the same basis as the audited annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for the fair statement of the Company’s financial position as of September 30, 2021 and the results of its operations and its cash flows for the nine months ended September 30, 2021 and 2020. The financial data and other information disclosed in these notes related to the nine months ended September 30, 2021 and 2020 are also unaudited. The results for the nine months ended September 30, 2021 are not necessarily indicative of results to be expected for the year ending December 31, 2021, any other interim periods, or any future year or period.

Impact of the

COVID-19

Coronavirus

The

COVID-19

pandemic has caused many governments to implement measures to slow the spread of the outbreak. The outbreak and government measures taken in response have had a significant impact, both direct and indirect, on businesses and commerce, as worker shortages have occurred, supply chains have been disrupted, and facilities and production sites have been suspended. The extent of the impact of the

COVID-19

pandemic on the business, operations, and development timelines and plans remains uncertain and will depend on certain developments, including the duration and spread of the outbreak and any new variants, and its impact on

F-38

Table of Contents

anticipated clinical trial plans, Clinical Research Organizations (“CROs”), contract manufacturing organizations, and other third parties with whom the Company does business. The

COVID-19

pandemic may affect the Company’s ability to initiate and complete preclinical studies, delay the initiation of future clinical trials, disrupt regulatory activities, or have other adverse effects on its business and operations. The pandemic could impact the Company’s ability to raise additional funds to support its operations. Moreover, the persistence of

COVID-19,

and future preventative measures implemented to help limit the spread of the illness may impact our ability to operate our business and may materially and adversely impact our financial condition, and results of operations.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to a significant concentration of credit risk consist of cash, cash equivalents, and short-term investments that are maintained in checking and money market accounts at one financial institution, which at times, may exceed federally insured limits. The Company’s short-term investments, if any, are limited to certain types of debt securities issued by the U.S. government, its agencies, and institutions with investment-grade credit ratings, and places restrictions on maturities and concentration by type and issuer. The Company believes that it is not exposed to significant credit risk due to the financial position of the institutions in which those deposits and short-term investments are held. As of September 30, 2021 (unaudited) and December 31, 2020, the Company has not experienced any credit losses in such accounts or investments.

Cash, Cash Equivalents, and Restricted Cash

Cash equivalents consist of amounts deposited in money market funds and securities with original maturity dates of three months or less which are stated at fair value.

The Company’s restricted cash consists of cash deposited with a financial institution as collateral for a letter of credit required under the Company’s headquarters and research facility leases. The restricted cash is presented separately from cash and cash equivalents and classified as

non-current

on the balance sheet, as the Company expects the cash to remain restricted for a period greater than one year.

The following table provides a reconciliation of cash and cash equivalents and restricted cash reported within the consolidated balance sheets that total to the amounts shown in the consolidated statements of cash flows for the Company:


	September 30,		December 31,
	2021		2020		2019
	(unaudited)
Cash and cash equivalents		73,692		30,537		5,301
Restricted cash		1,532		497		497

Total	$	75,224	$	31,034	$	5,798

Short-term Investments

Investments in marketable securities with original maturities less than 12 months from the balance sheet date, if any, are classified as short-term investments. Investments with original maturities of greater than 12 months from the balance sheet date, if any, are classified as long-term. The Company classifies all of its investments as

available-for-sale

and records such assets at estimated fair value in the balance sheet, with unrealized gains and losses, if any, reported as a component of other comprehensive loss within the consolidated statement of operations and comprehensive loss, and as a separate component of stockholders’ equity. These investments consist of corporate debt securities, U.S. Government securities, asset-based securities, and commercial paper, which are subject to minimal credit and market risk. The Company uses the specific

F-39

identification method to determine the amount of realized gains or losses on sales of marketable securities. Realized gains and losses on sales of securities and declines in the fair value of securities judged to be other than temporary are included in other income or expense. Unrealized gains and losses are included in other comprehensive loss. Interest on

available-for-sale

securities is included in interest income in the consolidated statements of operations and comprehensive loss.

Fair Value Measurements

Certain assets and liabilities of the Company are carried at fair value under U.S. GAAP. Fair value is defined as the exchange price that would be received for an asset or the exit price that would be paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The authoritative guidance on fair value measurements establishes a three-tier fair value hierarchy for disclosure of fair value measurements as follows:

•

Level 1 – Quoted prices in active markets for identical assets or liabilities.

•

Level 2 – Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data.

•

Level 3 – Unobservable inputs that are supported by little or no market activity that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies, and similar techniques.

To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

The estimated fair values of the Company’s cash and cash equivalents, short-term investments, if any, trade, and other receivables, accounts payable, and accrued expenses approximate their carrying values given their short-term nature.

The Company’s convertible notes and preferred stock tranche liability were carried at fair value from the date of issuance through their respective extinguishment in October 2020 and May 2021 (unaudited), determined according to Level 3 inputs in the fair value hierarchy described above.

Property and Equipment, Net

Property and equipment, net is stated at cost, net of accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets, which are as follows:


Computer equipment and software			3 years
Laboratory equipment			5-7 years
Furniture and fixtures			5-7 years
Leasehold improvements			Shorter of the lease term and the useful life

The Company capitalizes certain costs incurred during the construction phase of a project or asset into

construction-in-progress.

Once the construction is complete and the asset is placed into service, we transfer its carrying value into the appropriate fixed asset category and begin depreciating the value over its useful life.

When assets are retired or disposed of, any resulting gain or loss is included in net loss. Expenditures for maintenance and repairs are expensed as incurred.

Impairment of Long-Lived Assets

The Company evaluates its long-lived assets, such as property and equipment, net, for impairment whenever events or changes in circumstances indicate that the carrying value of assets may not be recoverable. Recoverability of these assets is measured by comparing their carrying value to the future net undiscounted cash flows the assets are expected to generate over their remaining economic life. If such assets are considered to be impaired, the amount of any impairment is measured as the difference between their carrying value and their fair value. If the useful life is shorter than originally estimated, the Company amortizes the remaining carrying value over the revised shorter useful life.

Leases

The Company determines if an arrangement is or contains a lease at inception. Operating leases are recorded on the consolidated balance sheets with

right-of-use

assets (“ROU”) representing the Company’s right to use an underlying asset for the lease term and lease liabilities representing the Company’s obligation to make lease payments. Operating lease

right-of-use

assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Operating lease

right-of-use

assets also include the effect of any lease payments made prior to or on lease commencement and excludes lease incentives and initial direct costs incurred, as applicable. As the implicit rate in the Company’s leases is typically unknown, the Company uses its incremental borrowing rate based on the information available at the lease commencement date in determining the present value of future lease payments. The Company gives consideration to its credit risk, the term of the lease, and total lease payments and adjusts for the impacts of collateral as necessary when calculating its incremental borrowing rates. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Operating lease expense is recognized on a straight-line basis over the lease term. Variable lease payments are recorded as an expense in the period incurred.

The Company has elected to not separate lease and

non-lease

components for any leases within its existing classes of assets and, as a result, accounts for any lease and

non-lease

components as a single lease component. The Company has also elected not to apply the recognition requirement for leases with a term of 12 months or less.

Revenue Recognition

Contract Revenue

Revenue is recognized when a customer obtains control of promised goods or services. The Company applies the following five steps to recognize revenue: (i) identify the contract with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to performance obligations in the contract; and (v) recognize revenue when (or as) the performance obligations are satisfied.

A performance obligation is defined as a promise to transfer a product or a service to a customer that is distinct. A product or a service is distinct if both (i) the customer can benefit from the product or the service either on its own or together with other resources that are readily available to the customer and (ii) the Company’s promise to transfer the product or the service to the customer is separately identifiable from other promises in the contract. Each distinct promise to transfer a product or a service is a unit of accounting for revenue recognition. If a promise to transfer a product or a service is not distinct from other promises in the contract, such promises should be combined into a single performance obligation. The assessment of each of these elements may require significant judgments.

F-41

Table of Contents

determination of the value of the underlying license relative to the option exercise price, including assumptions about technical feasibility and the probability of developing a candidate that would be subject to the option rights.

The transaction price is the amount of consideration the Company is entitled to receive in exchange for the transfer of control of a product or a service to a customer. The Company’s agreements may include both fixed and variable consideration. Fixed payments are included in the transaction price, while variable consideration, such as milestone payments and fees for research services, are estimated and constrained (if required) at the inception of the contract and evaluated on a periodic basis thereafter.

If a contract has multiple performance obligations, the Company allocates the transaction price to each distinct performance obligation based on the relative stand-alone selling price (“SSP”) of the performance obligation. The Company determines SSP at contract inception and at contract modification. Determining the SSP for performance obligations requires significant judgment. Changes in the key assumptions used to determine the SSP could have a significant effect on the allocation of arrangement consideration between multiple performance obligations.

For each distinct performance obligation, revenue is recognized as the Company transfers control of the product or the service applicable to such performance obligations. In instances where the Company first receives consideration in advance of satisfying its performance obligation, the Company classifies such consideration as deferred revenue until the Company satisfies such performance obligations. In instances where the Company first satisfies its performance obligation prior to its receipt of consideration, the consideration is a contract asset recorded in prepaid expenses and other current assets on the consolidated balance sheets.

Grant Income

The Company receives government grants that reimburse the Company for certain allowable costs for funded projects. Grant income is recognized on a systematic basis over the period in which the Company recognizes qualified research and development costs that grant is intended to compensate and there is reasonable assurance that the Company will meet the terms and conditions of the grant. This income is recorded as grant income in the consolidated statements of operations and comprehensive loss.

Grant payments received in excess of grant revenue earned are recognized as deferred revenue on the balance sheets, and grant income earned in excess of grant payments received is recognized as trade and other receivables on the consolidated balance sheets.

Research and Development Expenses

Research and development costs are expensed as incurred. Research and development costs consist of salaries and other personnel-related expenses, including associated stock-based compensation, lab supplies and services,

in-license

and technology costs, consulting and sponsored research fees, facility costs and depreciation expense.

Nonrefundable advance payments for goods and services that will be used or received in future research and development activities are deferred and recognized as an expense in the period in which the related goods are delivered, or services are performed.

The Company has acquired and may continue to acquire the rights to gene circuit or other technologies from third parties. The upfront payments to acquire a license, product, or rights, as well as any annual maintenance charges and future milestone payments, are immediately recognized as research and development expense provided that there is no alternative future use of the rights in other research and development projects.

Deferred Offering Costs

Deferred offering costs consists of incremental legal, accounting and other fees directly attributable to equity offerings. Deferred offering costs are capitalized within prepaid and other current assets on the consolidated balance sheets and are offset against proceeds of the offering in the consolidated statements of redeemable convertible preferred stock and stockholders’ deficit as a reduction of additional

paid-in

capital upon the completion of the equity offering. In the event the equity offering is terminated, all of the deferred offering costs are expensed within the Company’s consolidated statements of operations and comprehensive loss. For the nine months ended September 30, 2021 (unaudited) the Company expensed $2.2 million of previously deferred offering costs related to the suspended IPO within general and administrative expense on the consolidated statement of operations and comprehensive loss. As of September 30, 2021 (unaudited), the Company has recorded $0.1 million of deferred offering costs related to the pending SPAC merger. There are no deferred offering costs as of December 31, 2020 and 2019.

Commitments and Contingencies

The Company recognizes a liability with regard to loss contingencies when it believes it is probable a liability has occurred and the amount can be reasonably estimated. If some amount within a range of loss appears at the time to be a better estimate than any other amount within the range, the Company accrues that amount. When no amount within the range is a better estimate than any other amount, the Company accrues the minimum amount in the range. The Company has not recorded any such liabilities as of September 30, 2021 (unaudited) and December 31, 2020 and 2019.

Fair Value Option for Convertible Notes

The Company elected to account for its convertible notes at fair value as of the issuance date in order to measure those liabilities at amounts that more accurately reflect the current economic environment in which the Company operates. Accordingly, the Company recorded these convertible notes issued in August 2020 at fair value with changes in fair value recognized in change in fair value of convertible notes in the consolidated statements of operations and comprehensive loss. As a result of applying the fair value option, direct costs and fees related to the convertible notes were expensed in the period incurred.

Accretion and Classification of Redeemable Convertible Preferred Stock

The Company’s redeemable convertible preferred stock is recorded based on proceeds received, net of the related preferred stock tranche liability and issuance costs, and is classified outside of stockholders’ deficit on the consolidated balance sheets because the holders of such shares have liquidation rights in the event of a deemed liquidation that, in certain situations, are not solely within the control of the Company and would require the redemption of the then-outstanding redeemable convertible preferred stock. The Company’s Series A and Series B redeemable convertible preferred stock are subject to liquidation, dissolution, or winding up of the Company, either voluntary or involuntary (Note 6). Because the occurrence of a deemed liquidation event is not currently probable as of September 30, 2021 (unaudited), the carrying values of the redeemable convertible preferred stock are not being accreted to their redemption values. Subsequent adjustments to accrete the carrying values of the redeemable convertible preferred stock to its redemption price would be made only when a deemed liquidation event becomes probable.

Preferred Stock Tranche Liability

The Company’s Series B redeemable convertible preferred stock included an obligation whereby the investors agreed to buy, and the Company agreed to sell additional shares at a fixed price in the event that certain agreed-upon milestones were achieved or at the election of investors. This obligation was determined to be a freestanding financial instrument that should be accounted for as a liability at fair value (Notes 3 and 6). This

F-43

Table of Contents

preferred stock tranche liability was revalued at each reporting period through settlement with changes in the fair value recorded as a change in preferred stock tranche liability in the consolidated statements of operations and comprehensive loss. The fair value at settlement was reclassified to redeemable convertible preferred stock at such time.

Stock-Based Compensation

The Company recognizes stock-based compensation expense related to employees and

non-employees

over the requisite service period based on the grant date fair value of the awards. Compensation expense is recognized in the consolidated statements of operations using the straight-line method for awards that vest only upon the employee’s or

non-employee’s

continued service to the Company. The Company estimates the fair value of stock options granted using the Black-Scholes option pricing model and accounts for forfeitures as they occur.

Net Loss Per Share

The Company follows the

two-class

method when computing net loss per share as the Company has issued shares that meet the definition of participating securities. The

two-class

method determines net loss per share for each class of common and participating securities according to dividends declared or accumulated and participation rights in undistributed earnings. The

two-class

method requires loss available to common stockholders for the period to be allocated between common and participating securities based upon their respective rights to share in undistributed earnings as if all loss for the period had been distributed.

Basic net loss per share attributable to common stockholders is computed by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted net loss per share attributable to common stockholders is computed by adjusting net loss attributable to common stockholders to reallocate undistributed earnings based on the potential impact of dilutive securities. Diluted net loss per share attributable to common stockholders is computed by dividing the diluted net loss attributable to common stockholders by the weighted-average number of common shares outstanding for the period, including potential dilutive common shares. For purposes of this calculation, the Company’s outstanding stock options, redeemable convertible preferred stock, and potential issuance of redeemable convertible preferred stock under existing preferred stock tranches, are considered potential dilutive common shares.

The Company’s participating securities contractually entitle the holders of such securities to participate in dividends but do not contractually require the holders of such securities to participate in losses of the Company. Accordingly, in periods in which the Company reports a net loss, such losses are not allocated to such participating securities. In periods in which the Company reports a net loss attributable to common stockholders, diluted net loss per share attributable to common stockholders is the same as basic net loss per share attributable to common stockholders, since dilutive common shares are not assumed to have been issued if their effect is anti-dilutive.

Income Taxes

The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the consolidated financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the consolidated statement of operations in the period that includes the enactment date.

The Company recognizes net deferred tax assets to the extent that the Company believes these assets are more likely than not to be realized. In making such a determination, management considers all available positive

F-44

Table of Contents

and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income,

tax-planning

strategies, and results of recent operations. If management determines that the Company would be able to realize its deferred tax assets in the future in excess of their net recorded amount, management would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.

The Company records uncertain tax positions on the basis of a

two-step

process whereby (i) management determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (ii) for those tax positions that meet the

more-likely-than-not

recognition threshold, management recognizes the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority. The Company recognizes interest and penalties related to unrecognized tax benefits within income tax expense. Any accrued interest and penalties are included within the related tax liability. To date, there have been no interest charges or penalties related to unrecognized tax benefits.

Recently Adopted Accounting Pronouncements

In June 2016, the FASB issued ASU

No. 2016-13,

Financial Instruments-Credit Losses (Topic 326)

, which requires entities to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost. For trade receivables and other instruments, a new forward-looking expected loss model that generally results in the earlier recognition of allowances for losses will be required. The Company adopted this standard as of January 1, 2021 which did not have a material impact on its consolidated financial statements.

In August 2018, the FASB issued ASU

No. 2018-13,

Fair Value Measurement (Topic 820)

, which eliminates, modifies, and adds disclosure requirements for fair value measurements. The Company adopted this standard as of January 1, 2021, and modified its disclosures accordingly. The standard did not have a material impact on the Company’s consolidated financial statements.

In November 2018, the FASB issued ASU

No. 2018-18,

Collaborative Arrangements

, which clarifies that certain transactions between collaborative arrangement participants should be accounted for as revenue when the collaborative arrangement participant is a customer in the context of a unit of account and precludes recognizing as revenue consideration received from a collaborative arrangement participant if the participant is not a customer. The Company adopted this standard as of January 1, 2021 which did not have a material impact on its consolidated financial statements.

Accounting Pronouncements Not Yet Adopted

Convertible Notes

Due to certain embedded features within the convertible notes (Note 5), the Company elected to account for the convertible notes under the fair value option.

At issuance in August 2020, the convertible notes were recorded at fair value of $8.9 million, resulting in a loss on issuance of $0.9 million which is included in the change in fair value of convertible note.

1.	Fair value of the Series B redeemable convertible preferred stock was estimated using the Backsolve method.

The weighted average fair value of the tranche features on a per share basis was $0.172 as of October 22, 2020, $0.012 as of December 28, 2020 and December 31, 2020.

For the October 2020 issuance of Series B redeemable convertible preferred stock, certain investors received the right to participate in two additional closings at a fixed price which were valued as a call option (Note 6) when issued.

In connection with the December 2020 issuance of Series B redeemable convertible preferred stock, certain investors of Series B redeemable convertible preferred stock that held 48.65% of the Company’s outstanding shares and have 2 seats on the Company’s board of directors, forfeited their rights to participate in two additional closings of Series B redeemable convertible preferred stock which resulted in the measurement of the preferred stock tranche liability as a combination of a call option and forward contract.

In January 2021, the Company issued additional Series B redeemable convertible preferred stock, and recorded an addition to the tranche liability of $33 thousand (unaudited) in recognition of the obligation to sell additional shares at a fixed price in the event that certain agreed-upon milestones are achieved or at the election of investors.

In April 2021, the Company’s Board of Directors determined that certain technical milestones within the Series B agreements had been achieved and approved the notice to call tranches 2 and 3, subject to requisite stockholders’ written election and related waivers. The second and third closings occurred on May 14, 2021 and all 39,366,050 shares of Series B redeemable convertible preferred stock were acquired (unaudited) thereby extinguishing the preferred stock tranche liability.

5. Convertible Notes

In August 2020, the Company issued $8.0 million in convertible notes to existing investors, including related parties. Interest accrued on the convertible notes at an annual rate of 8%. The principal and accrued interest was payable on maturity in February 2021.

The outstanding balance of principal plus accrued and unpaid interest were automatically convertible at the sale of preferred stock of at least $25.0 million (the “Qualified Financing”). On conversion of the convertible notes in a Qualified Financing, the same class of preferred shares would be issued at a price equal to 90% of the fixed price per share paid by the purchasers of preferred stock participating in the Qualified Financing. In connection with the issuance and sale of Series B redeemable convertible preferred stock in October 2020 (Note 6), all of the outstanding principal and accrued interest of $8.1 million under the convertible notes was converted into 5,485,858 shares of Series B redeemable convertible preferred stock and the related preferred stock tranche liability.

The second and third closings occurred on May 14, 2021 and the Company issued 39,366,050 shares of Series B redeemable convertible preferred stock to investors for proceeds of $64.7 million for which no additional issuance costs were incurred (unaudited).

The following is a summary of the rights and privileges of the holders of redeemable convertible preferred stock:

Voting Rights

Each share of redeemable convertible preferred stock has voting rights equal to the number of shares of common stock into which such preferred stock is convertible. The holders of redeemable convertible preferred stock vote together with the holders of common stock as a single class for most matters.

The holders of Series A redeemable convertible preferred stock voting as a separate class are entitled to elect two directors. The holders of Series B redeemable convertible preferred stock voting as a separate class are entitled to elect two directors. The holders of common stock, voting as a separate class, are entitled to elect two directors of the Company. The holders of common stock and redeemable convertible preferred stock, voting as a single class, are entitled to elect the balance of the seven total directors of the Company.

Dividends

The holders of redeemable convertible preferred stock are entitled to receive, if and when declared by the Company’s board of directors,

non-cumulative

cash dividends at a rate of 8.0% per annum of the original issue price. These holders are also entitled to participate in dividends on common stock on an

as-converted

basis. As of December 31, 2019, and 2020, no dividends have been declared or paid to date.

Conversion

At the option of the holder, each share of redeemable convertible preferred stock is convertible into shares of common stock as determined by dividing the applicable original issue price by the applicable conversion price in effect at the time of conversion. The initial conversion price of both Series A and Series B redeemable convertible preferred stock is equal to the original issue price of $1.6427 per share. The conversion ratio for the redeemable convertible preferred stock shall be subject to appropriate adjustments for stock splits, stock dividends, combinations, recapitalizations, or the like. The conversion ratio at September 30, 2021 (unaudited) and December 31, 2020, respectively, is

one-to-one;

however, the conversion price is subject to anti-dilution provisions upon issuance of additional shares of common stock or other convertible securities. The holders of the Series A redeemable convertible preferred stock agreed to forfeit the anti-dilution provisions upon the issuance of Series B redeemable convertible preferred stock.

Each share of redeemable convertible preferred stock automatically converts into the number of shares of common stock into which such shares are convertible at the applicable conversion ratio upon the earlier: (i) the closing of the sale of shares of common stock in a qualified initial public offering (“IPO”) resulting in gross proceeds of at least $50.0 million or (ii) the vote or written consent of the holders of the majority of the then-outstanding shares of redeemable convertible preferred stock, voting together as a single class.

F-54

Table of Contents

If a holder of Series B redeemable convertible preferred stock fails to purchase all of its applicable tranche shares at or prior to the milestone closing, all of the holder’s shares of Series B redeemable convertible preferred stock will automatically convert into the number of shares of common stock into which such shares are convertible at the applicable conversion ratio. Such defaulting holder also forfeits its right to designate a member of or observer to the board of directors and any right to participate in any subsequent debt or equity financing of the Company.

Liquidation

In the event of any liquidation, dissolution, or winding up of the Company, either voluntary or involuntary, the holders of the Series B redeemable convertible preferred stock shall be entitled to receive, prior and in preference to any distribution of any of the assets of the Company to the holders of the Series A redeemable convertible preferred stock and common stock, an amount per share equal to the greater of (i) the Series B original issuance price, plus any dividends declared but unpaid thereon, or (ii) such amount per share as would have been payable had all shares of Series B redeemable convertible preferred stock been converted into shares of common stock immediately prior to such liquidation, dissolution, winding up or deemed liquidation event.

After the distribution to holders of Series B redeemable convertible preferred stock, the holders of the Series A redeemable convertible preferred stock shall be entitled to receive, prior and in preference to any distribution of any of the assets of the Company to the holders of the common stock, an amount per share equal to the greater of (i) the Series A original issuance price, plus any dividends declared but unpaid thereon, or (ii) such amount per share as would have been payable had all shares of Series A redeemable convertible preferred stock been converted into shares of common stock immediately prior to such liquidation, dissolution, winding up or deemed liquidation event. Upon completion of the distribution to the holders of the redeemable convertible preferred stock, all remaining legally available assets will be distributed ratably to the holders of common stock.

Classification

The Company has classified its redeemable convertible preferred stock as temporary equity on the consolidated balance sheets as the stock is contingently redeemable. Upon the occurrence of certain deemed liquidation events that are outside of the Company’s control, including liquidation, sale, or transfer of the Company, holders of the redeemable convertible preferred stock can cause redemption for cash. During the years ended December 31, 2019, and 2020, the Company did not adjust the carrying value of the redeemable convertible preferred stock to the deemed liquidation value of such shares as a deemed liquidation event was not probable. Additionally, one investor that owns 2,435,016 shares of Series B redeemable convertible preferred stock are redeemable by the holder at the original issuance price in the event that the Company uses any of the proceeds received from such investor for purposes other than operations and research and development activities.

7. Common Stock

Holders of common stock are entitled to one vote per share, and to receive dividends and, upon liquidation or dissolution, are entitled to receive all assets available for distribution to stockholders. The holders have no preemptive or other subscription rights, and there are no redemption or sinking fund provisions with respect to such shares. Common stock is subordinate to the redeemable convertible preferred stock with respect to dividend rights and rights upon liquidation, winding up, and dissolution of the Company. Through September 30, 2021 (unaudited) and December 31, 2020, no cash dividends have been declared or paid.

On September 30, 2021 (unaudited) and December 31, 2020, the Company was authorized to issue 138,000,000 shares of common stock and on December 31, 2019, the Company was authorized to issue

8. Revenue

The Company’s revenue consists of amounts received related to research services provided to customers.

Contract Revenue

In May 2019, the Company entered into a collaborative development agreement. The Company determined that the agreement contained three distinct promises; research and development, design services, and intellectual property, which will be accounted for as a single combined performance obligation of research and development services recognized over time. The development agreement included $0.3 million of fixed consideration allocated to a single performance obligation and an additional $0.3 million of variable consideration. At inception of the development agreement, it was not probable that a significant reversal of revenue would not occur and therefore the variable consideration was fully constrained.

In April 2021, the Company entered into a research collaboration and license agreement with Spark Therapeutics, Inc. (“Spark”). Under the agreement, the Company will be responsible for a research program, which includes designing, building and testing five cell type specific-synthetic promoters for use in developing certain gene therapies using the Company’s proprietary technology. The Company received an upfront payment from Spark of $3.0 million and Spark is obligated to reimburse the Company for costs and expenses incurred for the research program. The Company expects to complete the research program over a

two-year

period.

The Company assessed this agreement in accordance with ASC 606 and concluded that the contract counterparty, Spark, is a customer. The Company identified only one combined performance obligation in the agreement, which is to perform research services, the related joint research plan and committees for the five specified promoters. The Company determined that the research activities for each of the five promoters are not distinct given there is one single research plan that is performed by the same research team and research results for one promoter may provide insights for other promoters.

Pursuant to the agreement, once the research program is completed and the Company delivers a data package to Spark, Spark has 24 months (the “evaluation period”) to determine whether Spark will exercise its options to obtain field-limited, royalty-bearing licenses to develop, manufacture and commercialize promoters corresponding to each of the five specified promoters being researched. For each licensed promoter option that is exercised, the Company is eligible to receive a license fee, potential research, development and commercial milestone payments and royalties on product sales. Spark may generally terminate the agreement upon 90 days’ prior written notice or 180 days’ prior written notice if the licensed promoter is in clinical trials or is being commercialized at the time of termination.

The Company evaluated Spark’s optional rights to license, develop, manufacture and commercialize each of the promoter profiles to determine whether they provide Spark with any material rights to purchase the promoter

F-56

Table of Contents

licenses at an incremental discount. The Company’s proprietary technology used to develop the promoters is in early stages of development, so technological feasibility and probability of developing a product is highly uncertain. As a result, determining the SSP for the optional rights is subject to significant judgment. Given the subjectivity associated with determining the SSP for the right to a future license related to unproven technology at contract inception, the Company also evaluated whether the contract consideration associated with the research services represents the SSP for those services. The Company determined the transaction price, inclusive of the upfront payment and reimbursement of costs and expenses incurred for the research program, is commensurate with SSP for the research being conducted given the specialized nature and reliance on proprietary technology. Based on the Company’s assessment of the optional consideration and the qualitative factors of feasibility and probability of development combined with the quantitative assessment that research services are priced at their SSP, the Company concluded that the license option does not provide Spark with an incremental discount and therefore does not constitute a material right. The transaction price associated with the research services in this agreement consists of the fixed upfront amount of $3.0 million and variable consideration.

For both collaboration agreements, the Company will recognize the transaction price as research and development services are provided, using a cost-based input method to measure the progress toward completion of its performance obligation and to calculate the corresponding amount of revenue to recognize each period. The Company believes that the cost-based input method is the best measure of progress because other measurements would not reflect how the Company transfers the control related to the performance obligation to our customers.

The Company has recorded nil and $0.2 million of revenue for the nine months ended September 30, 2021 and 2020 (unaudited), respectively, which was previously included in the deferred revenue balances at the beginning of each period. The Company has recorded $0.2 million and nil of revenue for the years ended December 31, 2020 and 2019, respectively, which was previously included in the deferred revenue balances at the beginning of each period. Contract asset balances related to our collaboration agreements were $0.3 million and $0.3 million as of September 30, 2021 and 2020 (unaudited), respectively. Contract asset balances related to unbilled revenue for our collaboration agreements were $0.2 million and nil million as of December 31, 2020 and 2019, respectively within prepaid expenses and other current assets on the consolidated balance sheet.

Grant Income

In 2018, the National Institutes of Health awarded the Company a grant in the amount of $0.2 million to be used to support research and development for treating Inflammatory Bowel Disease. Eligible costs under the grant include direct personnel costs and materials and supplies.

In 2021, the Small Business Innovation Research awarded the Company a grant in the amount of $2.0 million over two years subject to meeting certain terms and conditions. The purpose of the grant is to support further development of

SENTI-202

for acute myeloid leukemia (“AML”) towards clinical development. As of September 30, 2021 (unaudited), the Company has received proceeds of $0.2 million.

Grant income was recognized when qualified research and development costs were incurred and the Company obtained reasonable assurance that the terms and conditions of the grant were met.

Entity-wide information

During the nine months ended September 30, 2021 (unaudited), Customer A accounted for approximately 84.6% of revenue. During the nine months ended September 30, 2020 (unaudited), Customer B accounted for approximately 85.0% of revenue and Customer C accounted for approximately 15.0% of revenue.

9. Stock-Based Compensation

In 2016, the Company adopted the 2016 Stock Incentive Plan (the “2016 Stock Incentive Plan”) authorizing the grant of incentive stock options (“ISOs”) and

non-statutory

stock options (“NSOs”) to eligible employees, officers and directors of, and consultants or advisors to, the Company. As of September 30, 2021 (unaudited) and December 31, 2020, the Company is authorized to issue up to 19,176,235 and 18,097,082, respectively, of shares of common stock under the Plan in which the exercise price of an ISO and NSO shall not be less than 100% of the estimated fair value of the shares on the date of grant, as determined by the board of directors. The exercise price of an ISO granted to a 10% stockholder shall not be less than 110% of the estimated fair value of the shares on the date of grant, as determined by the board of directors. Options generally vest over four years and are exercisable for up to 10 years after the date of the grant.

The following table summarizes the Company’s stock option activity:

Early Exercise of Stock Options into Restricted Stock

The Company has allowed specified option holders to exercise unvested options. The options that are exercised prior to vesting continue to vest according to the respective option agreement, and such unvested shares are subject to repurchase by the Company at the option holder’s original exercise price in the event the option holder’s service with the Company voluntarily or involuntarily terminates.

F-58

Table of Contents

The Company records proceeds from the early exercise of options as a liability within accrued expenses and other current liabilities as early exercise liability, net of current portion on the consolidated balance sheet, and reclassifies this liability to additional

paid-in

capital as the Company’s repurchase right lapses. The shares purchased by the option holders pursuant to the early exercise of stock options are not deemed, for accounting purposes, to be outstanding until those shares have vested. For the nine months ended September 30, 2021 (unaudited), the Company issued 2,619,677 shares of common stock upon exercise of unvested stock options, and as of September 30, 2021 (unaudited), 2,485,806 shares held by employees were subject to repurchase at an aggregate price of $1.3 million. As of December 31, 2020 and 2019, no options were early exercised and accordingly, the liability related to the payments for unvested shares was nil at each date.

Stock-Based Compensation Expense

In determining the fair value of the stock-based awards, the Company uses the assumptions below for the Black-Scholes option pricing model, which are subjective and generally requires significant judgment.

Fair Value of Common Stock

— The fair value of the shares of common stock has historically been determined by the Company’s board of directors as there was no public market for the common stock. The board of directors determines the fair value of the common stock by considering a number of objective and subjective factors, including: third-party valuations of the Company’s common stock, the valuation of comparable companies, the Company’s operating and financial performance, and general and industry-specific economic outlook, amongst other factors.

Expected Term

—The expected term represents the period that the Company’s stock options are expected to be outstanding and is determined using the simplified method (based on the

mid-point

between the vesting date and the end of the contractual term).

Volatility

—Because the Company is privately held and does not have an active trading market for its common stock for a sufficient period of time, the expected volatility was estimated based on the average volatility for comparable publicly-traded companies, over a period equal to the expected term of the stock option grants.

Risk-free Rate

—The risk-free rate assumption is based on the U.S. Treasury

zero-coupon

issues in effect at the time of grant for periods corresponding with the expected term of the option.

Dividends

—The Company has never paid dividends on its common stock and does not anticipate paying dividends on common stock. Therefore, the Company uses an expected dividend yield of zero.

The assumptions used to determine the grant date fair value of stock options granted to grantees were as follows, presented on a weighted-average basis:


	Nine Months Ended September 30,						Year Ended December 31,
	2021			2020			2020			2019

As of September 30, 2021 (unaudited), the total unrecognized stock-based compensation was approximately $7.2 million, which is expected to be recognized over a weighted-average period of 3.2 years. As of December 31, 2020, the total unrecognized stock-based compensation was approximately $1.1 million, which is expected to be recognized over a weighted-average period of 3.2 years.

10. Operating Leases

The Company’s operating leases are primarily for its corporate headquarters located in South San Francisco, California and for additional office and laboratory space located in Alameda, California (“Alameda lease”) that commenced on July 30, 2021. The corporate headquarters lease has an initial term of eight years expiring in 2027, with an option to renew for additional eight years unless canceled by either party thereafter. The Alameda lease has an initial term of eleven years expiring in 2032, with an option to renew the lease for up to two additional terms of five years. The exercise of these renewal options are not recognized as part of the ROU assets and lease liabilities, as the Company did not conclude, at the commencement date of the leases, that the exercise of renewal options or termination options was reasonably certain. The Alameda lease provides for a tenant improvement allowance of up to $17.5 million for the costs relating to the design, permitting and construction of the improvements, to be disbursed by the landlord no later than December 31, 2023. The Company was deemed to be the accounting owner of the tenant improvements primarily because the Company is the principal in the construction and design of the assets, is responsible for costs overruns and retains substantially all economic benefits from the leasehold improvements over their economic lives

Accordingly, the tenant improvement allowance is considered an incentive and was deducted from the initial measurement of the ROU asset and lease liability. The Company estimated the timing of tenant improvement reimbursements at the lease commencement date and upon receipt of the cash incentives, the Company will recognize the cash received as an increase in the lease liability.

The Company’s operating lease cost was $2.5 million and $2.0 million for the nine months ended September 30, 2021 and 2020 (unaudited), respectively, and was $2.7 million and $2.0 million for the years ended December 31, 2020 and 2019, respectively. Variable lease payments such as common area maintenance and parking fees were included in operating expenses and were $0.6 million for the nine months ended September 30, 2021 and 2020 (unaudited), respectively, and were $0.6 million and $0.5 million for the years ended December 31, 2020 and 2019, respectively. Rent expense for the Company’s short-term leases was nil for the nine months ended September 30, 2021 and 2020 (unaudited) and was nil and $0.2 for the years ended December 31, 2020 and 2019, respectively. No reimbursements have been received from the landlord as of September 30, 2021 (unaudited).

11. Income Taxes

For the calendar years ended December 31, 2020 and 2019, the tax effects of significant items comprising the Company’s deferred taxes are as follows:


	December 31,
	2020			2019
Deferred tax assets:
Accruals and reserves	$	526		$	405
Net operating losses		15,543			8,919

Other		2			10

Total deferred tax liabilities		(3,768	)		(3,958	)
Valuation allowance		(19,025	)		(11,154	)

Net deferred taxes	$	—		$	—

The Company records the tax benefit of net operating losses, temporary differences, and credit carryforwards as assets to the extent that management assesses that realization is “more likely than not.” Realization of the future tax benefits is dependent on the Company’s ability to generate sufficient taxable income within the carryforward period. Because of the Company’s recent history of operating losses, management believes that recognition of the deferred tax assets arising from the above-mentioned future tax benefits is currently not likely to be realized and, accordingly, has provided a valuation allowance.

The valuation allowance increased by approximately $7.9 million and $6.9 million during 2020 and 2019, respectively, and the Company’s deferred tax assets continue to be fully offset by the valuation allowance as at September 30, 2021 (unaudited). For the nine months ended September 30, 2021 (unaudited), the Company did not record an income tax provision.

Net operating losses and tax credit carryforwards as of December 31, 2020 are as follows (in thousands):


	Amount		Expiration Years
Net operating losses, federal (Post December 31, 2017)	$	51,100		Do Not Expire
Net operating losses, federal (Pre January 1, 2018)	$	3,508		2036-2037
Net operating losses, state	$	55,246		2036-2040
Tax credits, federal	$	1,973		2036-2040
Tax credits, state	$	1,891		N/A
Net operating losses, foreign	$	1,053		—

Utilization of the net operating loss carryforwards may be subject to a substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code of 1986, as amended, and similar state provisions. This annual limitation may result in the expiration of net operating losses and credits before utilization. We have not performed an analysis to determine the limitation of our net operating loss carryforwards.

The effective tax rate of the Company’s provision (benefit) for income taxes differs from the federal statutory rate as follows:


	December 31,
	2020			2019
Statutory rate		21.00	%		21.00	%
State tax		11.68	%		8.85	%

Tax credits		2.81	%		3.32	%
Fair value of series B preferred stock tranche liability		6.04	%		—	%
Valuation allowance		(41.48	)%		(33.72	)%

Total		0.00	%		0.00	%

As of December 31, 2020, gross unrecognized tax benefits were $0.8 million, all of which would not impact the Company’s effective tax rate if recognized. The Company has elected to include interest and penalties as a component of tax expense. For the nine months ended September 30, 2021 (unaudited) and during the years ended December 31, 2020 and 2019, the Company did not recognize accrued interest and penalties related to unrecognized tax benefits. The Company does not anticipate that the amount of existing unrecognized tax benefits will significantly increase or decrease during the next 12 months.

The Company files income tax returns in the U.S. federal and California tax jurisdictions. The federal and state income tax returns from inception to September 30, 2021 (unaudited) remain subject to examination.

12. Net Loss Per Share

13. Commitments and Contingencies

In the ordinary course of business, we enter into contractual agreements with third parties that include

non-cancelable

payment obligations, for which we are liable in future periods.

The following table summarizes our contractual obligations and commitments at December 31, 2020 (in thousands):


	December 31, 2020
	Payments Due by Period
	Total		Less Than 1 Year		1 to 3 Years		4 to 5 Years		More Than 5 years
Purchase commitments	$	1,384	$	1,076	$	308	$	—	$	—

Total	$	1,384	$	1,076	$	308	$	—	$	—

Except as noted below, there were no material changes to our contractual obligations and commitments during the nine months ended September 30, 2021 (unaudited).

On June 3, 2021, the Company entered into a lease agreement for a new cGMP facility in Alameda, California to support planned initial clinical trials for our product candidates (Note 10). The lease will expire in 2027 with future undiscounted operating lease payments of $46.0 million over an initial lease period of eleven years.

In 2021, the Company began construction of the cGMP facility. As of September 30, 2021 (unaudited) the Company paid $0.8 million in construction costs and the purchase commitments amounted to approximately $3.0 million. The agreements with the construction company provide for termination following a certain period after notice. Upon termination the Company will be responsible for payment for work performed to date.

During the nine months ended September 30, 2021 (unaudited), the Company entered into a three-year collaboration and option agreement with BlueRock Therapeutics LP (“BlueRock”) under which the Company

F-64

Table of Contents

granted BlueRock an option to acquire an exclusive or

non-exclusive

license to develop, manufacture and commercialize cell therapy products (Note 14). In consideration for the option, the Company is responsible for up to $10.0 million in costs and expenses incurred over the three-year term.

The Company has entered into license agreements under which they are obligated to make specified milestone and royalty payments. Future payments under these agreements are not considered contractual obligations since the payments under these agreements are contingent upon future events, such as the Company’s achievement of specified development, regulatory, and sales milestones, or generating product sales. As of September 30, 2021 (unaudited), the Company is unable to estimate the timing or likelihood of achieving these milestones or generating future product sales.

Leases

The Company’s commitments under its leases are described in Note 10.

Legal Proceedings

The Company is subject to claims and assessments from time to time in the ordinary course of business but does not believe that any such matters, individually or in the aggregate, will have a material adverse effect on the Company’s financial position, results of operations, or cash flows.

Indemnifications

In the ordinary course of business, the Company enters into agreements that may include indemnification provisions. Pursuant to such agreements, the Company may indemnify, hold harmless and defend an indemnified party for losses suffered or incurred by the indemnified party. Some of the provisions will limit losses to those arising from third party actions. In some cases, the indemnification will continue after the termination of the agreement. The maximum potential amount of future payments the Company could be required to make under these provisions is not determinable. The Company has never incurred material costs to defend lawsuits or settle claims related to these indemnification provisions and has never accrued any liabilities related to such obligations in its consolidated financial statements. The Company has also entered into indemnification agreements with its directors and officers that may require the Company to indemnify its directors and officers against liabilities that may arise by reason of their status or service as directors or officers to the fullest extent permitted by Delaware corporate law. The Company currently has directors’ and officers’ insurance.

14. Related Parties

As discussed in Note 6, the Company issued Series A convertible redeemable preferred stock and Series B redeemable convertible preferred stock in February 2018 and October 2020, respectively, to certain related parties, including New Enterprise Associates 15, L.P. and its affiliates (“NEA”) and 8VC and its affiliates (“8VC”).

In February 2018, the outstanding convertible notes held by NEA and 8VC, as well as Timothy Lu, Chief Executive Officer, converted into additional shares of Series A redeemable convertible preferred stock while in October 2020, the outstanding convertible notes held by NEA and 8VC converted into additional shares of Series B redeemable convertible preferred stock, both in accordance with the terms of the note agreements.

NEA held 13,505,035 shares of outstanding Series A redeemable convertible preferred stock as of September 30, 2021 (unaudited) and as of both December 31, 2020 and 2019, as well as 2,742,931 of outstanding

F-65

Table of Contents

Series B redeemable convertible preferred stock as of September 30, 2021 (unaudited) and December 31, 2020. 8VC held 9,052,387 of outstanding Series A redeemable convertible preferred stock as of September 30, 2021 (unaudited) and as of both December 31, 2020 and 2019 as well as 1,662,398 of outstanding Series B redeemable convertible preferred stock as of September 30, 2021 (unaudited) and December 31, 2020. Timothy Lu held 158,950 of outstanding redeemable convertible preferred stock as of September 30, 2021 (unaudited), December 31, 2020 and 2019. Timothy Lu and family held 8,100,000 of common stock as of September 30, 2021 (unaudited), December 31, 2020 and 2019. Timothy Lu, NEA, and 8VC held three of the seven seats on the Company’s Board of Directors as of September 30, 2021 (unaudited) and three of the five seats on the Company’s Board of Directors as of December 31, 2020.

As Chief Executive Officer, Timothy Lu was paid $0.5 million and $0.4 million as compensation for the nine months ended September 30, 2021 and 2020 (unaudited), respectively, and an additional sum of $0.2 million was accrued as a bonus for the nine months ended September 30, 2021 (unaudited). For the nine months ended September 30, 2020 (unaudited), no additional sum was accrued as a bonus. Timothy Lu was paid $0.4 million and $0.4 million as compensation, and an additional sum of $0.2 million and $0.2 million was accrued as a bonus for the years ended December 31, 2020 and 2019, respectively.

On May 21, 2021, the Company entered into a collaboration and option agreement (“BlueRock Agreement”) with BlueRock Therapeutics LP (“BlueRock”), pursuant to which the Company granted to BlueRock an option (“BlueRock Option”), on a collaboration

program-by-collaboration

program basis, to obtain an exclusive or

non-exclusive

license to develop, manufacture and commercialize cell therapy products that contain cells of specified types and which incorporate an option gene circuit from such collaboration program or a closely related derivative gene circuit. The Company is responsible for up to $10 million in costs and expenses incurred in connection with the research plan and related activities to be conducted over a term of three years as specified in the collaboration and option agreement. If the Company and BlueRock agree to add new research activities to the research plan, then BlueRock will be obligated to reimburse the Company for the costs and expenses incurred that, together with costs and expenses incurred under the initial research plan, exceed $10 million (unaudited).

The Company concluded that the Agreement is not within the scope of ASC 808,

Collaborative Arrangements

, because the Company did not receive any consideration and therefore, is not exposed to both significant risks and rewards for the arrangement. The Company also determined that the agreement is also not currently within the scope of ASC 606,

Revenue Recognition

(“ASC 606”) because the BlueRock Agreement does not currently meet the criteria of a contract with a customer, and will not be within scope of ASC 606 until any consideration is paid. Potential future milestone payments and royalties are subject to BlueRock’s exercise of the BlueRock Option and execution of a commercial license agreement by both parties. Under the BlueRock Agreement, the specific financial terms for milestone payments and royalties will be negotiated and agreed to only after the option is exercised.

BlueRock is a wholly-owned subsidiary of Bayer Healthcare LLC which held 27,393,924 and 9,131,308 shares of outstanding Series B redeemable convertible preferred stock as of September 30, 2021 (unaudited) and December 31, 2020, respectively, and holds one of the seven seats on the Company’s Board of Directors as of September 30, 2021 (unaudited) and one of the five seats as of December 31, 2020. Bayer Healthcare LLC’s parent company is Bayer AG, which served as the lead investor in our Series B financing through its Leaps by Bayer unit. Accordingly, BlueRock is considered a related party. The Company concluded that the BlueRock Agreement should not be combined with the issuance of the Series B redeemable convertible preferred stock on May 14, 2021 as the price paid per share of $1.6427 was lower than the fair value of $2.03 (Note 3) and therefore, there was no excess value to allocate to the BlueRock Agreement.

15. Subsequent Events

The Company has evaluated subsequent events from the December 31, 2020 balance sheet date through April 12, 2021, the date at which the audited consolidated financial statements were available to be issued.

Pending Merger with Dynamics Special Purpose Corp. (unaudited)

On December 19, 2021, the Company entered into a definitive Business Combination Agreement with Dynamics Special Purpose Corp. (“DYNS”), a publicly traded special purpose acquisition company (“SPAC”). Under the terms of the proposed transaction, DYNS will merge with the Company at an estimated combined enterprise value of approximately $276 million. The cash components of the transaction will be funded by DYNS’ cash in trust of $230.0 million (assuming no redemptions) as well as a $66.8 million private placement of common stock at $10.00 per share from various accredited investors.

Grant of Stock Options (unaudited)

On October 27, 2021 and on November 23, 2021 the Company granted an aggregate quantity of 2,294,000 options to purchase Common Stock under the Company’s 2016 Stock Incentive Plan. Each option vests monthly over a four year period and has an exercise price $1.46 per share.

On December 19, 2021 the Company increased the total number of Company Common Shares reserved for issuance by 46,374,930, such that a total of 65,551,165 Company Common Shares are reserved for issuance under the 2016 Stock Incentive Plan.

On December 19, 2021 the Company granted an aggregate of 46,374,930 options to purchase Common Stock under the Company’s 2016 Stock Incentive Plan. Each option has an exercise price of $1.94 and vesting is subject to a service condition. A majority of these options granted are also subject to the consummation of the merger with DYNS and may be subject to the achievement of specified market price of the Company’s common stock subsequent to the merger with DYNS.

On February 12, 2022, the Company entered into Amendment No. 1 to the Business Combination Agreement, to restructure certain option grants made at the time the Business Combination Agreement was signed. In particular, certain Senti executives agreed to forfeit certain options granted to them at the time the Business Combination Agreement was signed depending on the level of redemptions of DYNS Class A Common Stock at Closing. In addition, it was agreed that the vesting period for the options held by executives whose options may be subject to forfeiture (as described above) will commence at Closing.

any proposed or actual business relationship between DYNS or any of its Representatives of Affiliates, on the one hand, and the Company or any of its Representatives or Affiliates, on the other hand, or any other matter, and regardless of whether such action, suit, claim or other proceeding arises based on contract, tort, equity or any other theory of legal liability (any and all such actions, suits, claims or other proceedings are collectively referred to hereafter as the “

Trust Account Released Claims

”). The Company, on its own behalf and on behalf of its Representatives and Affiliates, hereby irrevocably and unconditionally waives any Trust Account Released Claims that it or any of its Representatives or Affiliates may have against the Trust Account (including in respect of any distributions therefrom) now or in the future as a result of, or arising out of, any discussions, negotiations, agreements or Contracts with DYNS or its Representatives or Affiliates, and will not seek recourse against the Trust Account (including in respect of any distributions therefrom) for any reason whatsoever (including for an alleged breach of any agreement with DYNS or its Affiliates).

Resale Shelf Registration Rights

2.1.1

Registration Statement Covering Resale of Registrable Securities

A-5

Table of Contents

Securities then held by such Investors that are not covered by an effective resale registration statement (the “

Resale Shelf Registration Statement

”). The Company shall use commercially reasonable efforts to cause the Resale Shelf Registration Statement to be declared effective as soon as possible after filing, and in no event later than the earlier of (x) 60

calendar day after the Closing (or 90

calendar day if the SEC notifies (orally or in writing, whichever is earlier) the Company that it will “review” the Resale Shelf Registration Statement) and, (y) the 5

Business Day after the Company is notified (orally or in writing, whichever is earlier) by the SEC that the Resale Shelf Registration Statement will not be “reviewed” or will not be subject to further review. Once effective the Company shall use commercially reasonable efforts to keep the Resale Shelf Registration Statement continuously effective under the Securities Act at all times until the expiration of the Effectiveness Period (as defined below). In the event that the Company files a Form

S-1

pursuant to this

Section

2.1

, the Company shall use its commercially reasonable efforts to convert the Form

S-1

to a Form

S-3

promptly after the Company is eligible to use Form

S-3.

The Resale Shelf Registration Statement shall provide that the Registrable Securities may be sold pursuant to any method or combination of methods legally available to, and requested by, the Investors, including the registration of the distribution to its shareholders, partners, members or other affiliates. Without limiting the foregoing, subject to any comments from the Commission, each Registration Statement filed pursuant to this

Section

2.1.1

shall include a “plan of distribution” approved by Senti Investors holding a majority of the Registrable Securities.

2.1.2

Notification and Distribution of Materials

. The Company shall promptly notify the Investors in writing of the effectiveness of the Resale Shelf Registration Statement and shall furnish to them, without charge, such number of copies of the Resale Shelf Registration Statement (including any amendments, supplements and exhibits), the prospectus contained therein (including each preliminary prospectus and all related amendments and supplements) and any documents incorporated by reference in the Resale Shelf Registration Statement or such other documents as the Investors may reasonably request in order to facilitate the sale of the Registrable Securities in the manner described in the Resale Shelf Registration Statement.

2.1.3

Amendments and Supplements

. Subject to the provisions of

Section

2.1.1

above, the Company shall promptly prepare and file with the Commission from time to time such amendments and supplements to the Resale Shelf Registration Statement and prospectus used in connection therewith as may be necessary to keep the Resale Shelf Registration Statement effective and to comply with the provisions of the Securities Act with respect to the disposition of all the Registrable Securities during the Effectiveness Period (as defined below).

2.1.4

Reduction of Shelf Offering

. Notwithstanding the registration obligations set forth in this

Section

2.1

, in the event the Commission informs the Company (the “

Rule 415

Notice

”) that all of the Registrable Securities cannot, as a result of the application of Rule 415, be registered for resale as a secondary offering on a single registration statement, the Company agrees to promptly (i) inform each of the holders thereof and use its commercially reasonable efforts to file an amendment or amendments to the Resale Shelf Registration Statement as required by the Commission and/or (ii) withdraw the Resale Shelf Registration Statement and file a new registration statement (a “

New Registration Statement

SEC Guidance

”), including, without limitation, Compliance and Disclosure Interpretation 612.09. Notwithstanding any other provision of this Agreement, if any SEC Guidance sets forth a limitation of the number of Registrable Securities permitted to be registered on a particular Registration Statement as a secondary offering (and notwithstanding that the Company used diligent efforts to advocate with the Commission for the registration of all or a greater number of Registrable Securities), unless otherwise directed in writing by a holder as to its Registrable Securities, the number of Registrable Securities to be registered on such Registration Statement will be reduced on a Pro Rata basis, subject to a determination by the Commission that certain Investors must be reduced first based on the number of Registrable Securities held by

A-6

Table of Contents

such Investors. In the event the Company amends the Resale Shelf Registration Statement or files a New Registration Statement, as the case may be, under clauses (i) or (ii) above, the Company will use its commercially reasonable efforts to file with the Commission, as promptly as allowed by Commission or SEC Guidance provided to the Company or to registrants of securities in general, one or more registration statements on Form

S-1,

Form

S-3

If the Company shall not be able to register for resale all of the Registrable Securities on the Resale Shelf Registration Statement within three (3) months following the date of the Company’s receipt of the Commission’s Notice, then, until such Resale Shelf Registration Statement is effective, each of the Senti Investors shall be entitled to demand registration rights pursuant to Section 2.2 below as long as the demand request is a proposal to sell Registrable Securities with an aggregate market price at the time of request of not less than $5,000,000 (the “

Shelf Demand Right

”). Shelf Demand Rights shall not be counted as Demand Registrations under Section 2.2.

No Investor shall be named as an “underwriter” in any Registration Statement filed pursuant to this

Each Registration Statement (and each amendment or supplement thereto, and each request for acceleration of effectiveness thereof) shall be provided to (and shall be subject to the approval, which shall not be unreasonably withheld or delayed, of) the Investors prior to its filing with, or other submission to, the Commission.

non-affiliate

paperwork provided by such Investor, or (D) if at any time on or after the date that is one year after the Form 10 Disclosure Filing Date such Investor certifies that it is not an affiliate of the Company and that such Investor’s holding period for purposes of Rule 144 in respect of such Registrable Securities is at least six (6) months, or (E) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission) as determined in good faith by counsel to the Company or set forth in a legal opinion delivered by nationally recognized counsel to the Investor (collectively, the “

Unrestricted Conditions

”). The Company agrees that following the date that the Resale Shelf Registration Statement has been declared effective by the Commission or at such time as any of the Unrestricted Conditions is met or such legend is otherwise no longer required it will, no later than two (2) Business Days following the delivery by an Investor to the Company or its transfer agent of a certificate representing any Registrable Securities, issued with a restrictive legend, (or, in the case of Registrable Securities represented by book entries, delivery by an Investor to the Company or its transfer agent of a legend removal request) deliver or cause to be delivered to such Investor a certificate or, at the request of such Investor, deliver or cause to be delivered such Registrable Securities to such Investor by crediting the account of such Investor’s prime broker with DTC through its Deposit/Withdrawal at Custodian (DWAC) system, in each case, free from all restrictive and other legends and stop transfer or similar instructions or notations.

The Company agrees to indemnify and hold harmless, to the fullest extent permitted by law, each Investor and each other holder of Registrable Securities, and each of their respective officers, employees, affiliates, directors, partners, members, attorneys and agents, and each person, if any, who controls an Investor and each other holder of Registrable Securities (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) (each, an “

Investor Indemnified Party

”), from and against any expenses, losses, judgments, claims, damages or liabilities, whether joint or several, (including reasonable and documented costs of investigation and legal expenses and any indemnity and contribution payments made to underwriters) arising out of or based upon any untrue statement (or allegedly untrue statement) of a material fact contained in any Registration Statement under which the sale of such Registrable Securities was registered under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained in the Registration Statement, or any amendment or supplement to such Registration Statement, or arising out of or based upon any omission (or alleged omission) to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or any violation by the Company of the Securities Act or any rule or regulation promulgated thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration; and the Company shall promptly reimburse the Investor Indemnified Party for any legal and any other expenses reasonably incurred by such Investor Indemnified Party in connection with investigating and defending any such expense, loss, judgment, claim, damage, liability or action;

provided

however

, that the Company will not be liable in any such case to the extent that any such expense, loss, claim, damage or liability is finally judicially determined to have arisen out of or resulted from any untrue statement or allegedly untrue statement or omission or alleged omission made in such Registration Statement, preliminary prospectus, final prospectus, or summary prospectus, or any such amendment or supplement, in reliance upon and in conformity with information furnished to the Company, in writing, by such selling holder expressly for use therein or to the extent related to any selling holder’s violation of the federal securities laws (including Regulation M) or failure to sell the Registrable Securities in accordance with the plan of distribution contained in the prospectus.

4.2

Indemnification by Holders of Registrable Securities

. Each selling holder of Registrable Securities will, in the event that any Registration is being effected under the Securities Act pursuant to this Agreement of any Registrable Securities held by such selling holder, indemnify and hold harmless to the fullest extent permitted by law the Company, each of its directors and officers, and each other selling holder of Registrable Securities and each other person, if any, who controls such other selling holder within the meaning of the Securities Act, against any losses, claims, judgments, damages or liabilities, only insofar as such losses, claims, judgments, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or allegedly untrue statement of a material fact contained in any Registration Statement under which the sale of such Registrable Securities was registered under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained in the Registration Statement, or any amendment or supplement to the Registration Statement, or arise out of or are based upon any omission or the alleged omission to state a material fact required to be stated therein or necessary to make the statement therein not misleading, if the statement or omission was made expressly in reliance upon and in conformity with information furnished in writing to the Company by such selling holder in writing expressly for use therein, or (ii) such selling holder’s failure to sell the Registrable Securities in accordance with the plan of distribution contained in the prospectus, and shall reimburse the Company, its directors and officers, and each other selling holder or controlling person for any legal or other expenses reasonably incurred by any of them in connection with investigation or defending any such loss, claim, damage, liability or action. Each selling holder’s indemnification obligations hereunder shall be several and not joint and shall be limited to the amount of any net proceeds actually received by such selling holder upon the sale of Registrable Securities giving rise to such indemnification obligations.

4.3

Conduct of Indemnification Proceedings

. Promptly after receipt by any person of any notice of any loss, claim, damage or liability or any action in respect of which indemnity may be sought pursuant to

Sections 4.1

4.2

, such person (the “

Indemnified Party

”) shall, if a claim in respect thereof is to be made against any other

A-16

Table of Contents

person for indemnification hereunder, notify such other person (the “

Indemnifying Party

”) in writing of the loss, claim, judgment, damage, liability or action; provided, however, that the failure by the Indemnified Party to notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability which the Indemnifying Party may have to such Indemnified Party hereunder, except and solely to the extent the Indemnifying Party is actually prejudiced by such failure. If the Indemnified Party is seeking indemnification with respect to any claim or action brought against the Indemnified Party, then the Indemnifying Party shall be entitled to participate in such claim or action, and, to the extent that it wishes, jointly with all other Indemnifying Parties, to assume control of the defense thereof with counsel satisfactory to the Indemnified Party. After notice from the Indemnifying Party to the Indemnified Party of its election to assume control of the defense of such claim or action, the Indemnifying Party shall not be liable to the Indemnified Party for any legal or other expenses subsequently incurred by the Indemnified Party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that in any action in which both the Indemnified Party and the Indemnifying Party are named as defendants, the Indemnified Party shall have the right to employ separate counsel (but no more than one such separate counsel, which counsel is reasonably acceptable to the Indemnifying Party) to represent the Indemnified Party and its controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Indemnified Party against the Indemnifying Party, with the fees and expenses of such counsel to be paid by such Indemnifying Party if, based upon the written opinion of counsel of such Indemnified Party, representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, consent to entry of judgment or effect any settlement of any claim or pending or threatened proceeding in respect of which the Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such judgment or settlement includes an unconditional release of such Indemnified Party from all liability arising out of such claim or proceeding.

4.4

Contribution

4.4.1 If the indemnification provided for in the foregoing

Sections 4.1

4.2

and

4.3

is unavailable to any Indemnified Party in respect of any loss, claim, damage, liability or action referred to herein, then each such Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, claim, damage, liability or action in such proportion as is appropriate to reflect the relative fault of the Indemnified Parties and the Indemnifying Parties in connection with the actions or omissions which resulted in such loss, claim, damage, liability or action, as well as any other relevant equitable considerations. The relative fault of any Indemnified Party and any Indemnifying Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by such Indemnified Party or such Indemnifying Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

4.4.2 The parties hereto agree that it would not be just and equitable if contribution pursuant to this

Section

4.4

were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in

Section

4.4.1

4.4.3 The amount paid or payable by an Indemnified Party as a result of any loss, claim, damage, liability or action referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this

Section

4.4

, no holder of Registrable Securities shall be required to contribute any amount in excess of the dollar amount of the net proceeds (after payment of any underwriting fees, discounts, commissions or taxes) actually received by such holder from the sale of Registrable Securities which gave rise to such contribution obligation. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

Section

6.1

The foregoing notwithstanding, to the extent any Investor is granted a release or waiver from the restrictions contained in this Section 6 prior to the expiration of the

Lock-Up

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers.

Our amended and restated certificate of incorporation, to be in effect upon consummation of the Business Combination, provides that all of our directors, officers, employees and agents shall be entitled to be indemnified by us to the fullest extent permitted by Section 145 of the DGCL. Section 145 of the DGCL concerning indemnification of officers, directors, employees and agents is set forth below.

Section 145. Indemnification of officers, directors, employees and agents; insurance.

(a)

A corporation shall have power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that the person’s conduct was unlawful.

(b)

A corporation shall have power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

(c)

To the extent that a present or former director or officer of a corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in subsections (a) and (b) of this section, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection therewith.

(d)

Any indemnification under subsections (a) and (b) of this section (unless ordered by a court) shall be made by the corporation only as authorized in the specific case upon a determination that indemnification of the present or former director, officer, employee or agent is proper in the circumstances because the person has met the applicable standard of conduct set forth in subsections (a) and (b) of this section. Such determination shall be made, with respect to a person who is a director

II-1

Table of Contents

or officer at the time of such determination, (1) by a majority vote of the directors who are not parties to such action, suit or proceeding, even though less than a quorum, or (2) by a committee of such directors designated by majority vote of such directors, even though less than a quorum, or (3) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion, or (4) by the stockholders.

(e)

Expenses (including attorneys’ fees) incurred by an officer or director in defending any civil, criminal, administrative or investigative action, suit or proceeding may be paid by the corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the corporation as authorized in this section. Such expenses (including attorneys’ fees) incurred by former officers and directors or other employees and agents may be so paid upon such terms and conditions, if any, as the corporation deems appropriate.

(f)

The indemnification and advancement of expenses provided by, or granted pursuant to, the other subsections of this section shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in such person’s official capacity and as to action in another capacity while holding such office. A right to indemnification or to advancement of expenses arising under a provision of the certificate of incorporation or a bylaw shall not be eliminated or impaired by an amendment to such provision after the occurrence of the act or omission that is the subject of the civil, criminal, administrative or investigative action, suit or proceeding for which indemnification or advancement of expenses is sought, unless the provision in effect at the time of such act or omission explicitly authorizes such elimination or impairment after such action or omission has occurred.

(g)

A corporation shall have power to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the corporation would have the power to indemnify such person against such liability under this section.

(h)

For purposes of this section, references to “the corporation” shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers, and employees or agents, so that any person who is or was a director, officer, employee or agent of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under this section with respect to the resulting or surviving corporation as such person would have with respect to such constituent corporation if its separate existence had continued.

(i)

For purposes of this section, references to “other enterprises” shall include employee benefit plans; references to “fines” shall include any excise taxes assessed on a person with respect to any employee benefit plan; and references to “serving at the request of the corporation” shall include any service as a director, officer, employee or agent of the corporation which imposes duties on, or involves services by, such director, officer, employee or agent with respect to an employee benefit plan, its participants or beneficiaries; and a person who acted in good faith and in a manner such person reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interests of the corporation” as referred to in this section.

(j)

The indemnification and advancement of expenses provided by, or granted pursuant to, this section shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to

II-2

Table of Contents

be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person.

(k)

The Court of Chancery is hereby vested with exclusive jurisdiction to hear and determine all actions for advancement of expenses or indemnification brought under this section or under any by law, agreement, vote of stockholders or disinterested directors, or otherwise. The Court of Chancery may summarily determine a corporation’s obligation to advance expenses (including attorneys’ fees).

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers, and controlling persons pursuant to the foregoing provisions, or otherwise, we have been advised that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment of expenses incurred or paid by a director, officer or controlling person in a successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, we will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to the court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

In accordance with Section 102(b)(7) of the DGCL, our amended and restated certificate of incorporation provides that no director shall be personally liable to us or any of our stockholders for monetary damages resulting from breaches of their fiduciary duty as directors, except to the extent such limitation on or exemption from liability is not permitted under the DGCL. The effect of this provision of our amended and restated certificate of incorporation is to eliminate our rights and those of our stockholders (through stockholders’ derivative suits on our behalf) to recover monetary damages against a director for breach of the fiduciary duty of care as a director, including breaches resulting from negligent or grossly negligent behavior, except, as restricted by Section 102(b)(7) of the DGCL. However, this provision does not limit or eliminate our rights or the rights of any stockholder to seek

non-monetary relief,

such as an injunction or rescission, in the event of a breach of a director’s duty of care.

If the DGCL is amended to authorize corporate action further eliminating or limiting the liability of directors, then, in accordance with our amended and restated certificate of incorporation, the liability of our directors to us or our stockholders will be eliminated or limited to the fullest extent authorized by the DGCL, as so amended. Any repeal or amendment of provisions of our amended and restated certificate of incorporation limiting or eliminating the liability of directors, whether by our stockholders or by changes in law, or the adoption of any other provisions inconsistent therewith, will (unless otherwise required by law) be prospective only, except to the extent such amendment or change in law permits us to further limit or eliminate the liability of directors on a retroactive basis.

Our amended and restated certificate of incorporation also provides that we will, to the fullest extent authorized or permitted by applicable law, indemnify our current and former officers and directors, as well as those persons who, while directors or officers of our corporation, are or were serving as directors, officers, employees or agents of another entity, trust or other enterprise, including service with respect to an employee benefit plan, in connection with any threatened, pending or completed proceeding, whether civil, criminal, administrative or investigative, against all expense, liability and loss (including, without limitation, attorney’s fees, judgments, fines, ERISA excise taxes and penalties and amounts paid in settlement) reasonably incurred or suffered by any such person in connection with any such proceeding.

Notwithstanding the foregoing, a person eligible for indemnification pursuant to our amended and restated certificate of incorporation will be indemnified by us in connection with a proceeding initiated by such person only if such proceeding was authorized by our board of directors, except for proceedings to enforce rights to indemnification.

II-3

Table of Contents

The right to indemnification which is conferred by our amended and restated certificate of incorporation is a contract right that includes the right to be paid by us the expenses incurred in defending or otherwise participating in any proceeding referenced above in advance of its final disposition, provided, however, that if the DGCL requires, an advancement of expenses incurred by our officer or director (solely in the capacity as an officer or director of our corporation) will be made only upon delivery to us of an undertaking, by or on behalf of such officer or director, to repay all amounts so advanced if it is ultimately determined that such person is not entitled to be indemnified for such expenses under our amended and restated certificate of incorporation or otherwise.

The rights to indemnification and advancement of expenses will not be deemed exclusive of any other rights which any person covered by our amended and restated certificate of incorporation may have or hereafter acquire under law, our amended and restated certificate of incorporation, our bylaws, an agreement, vote of stockholders or disinterested directors, or otherwise.

Any repeal or amendment of provisions of our amended and restated certificate of incorporation affecting indemnification rights, whether by our stockholders or by changes in law, or the adoption of any other provisions inconsistent therewith, will (unless otherwise required by law) be prospective only, except to the extent such amendment or change in law permits us to provide broader indemnification rights on a retroactive basis, and will not in any way diminish or adversely affect any right or protection existing at the time of such repeal or amendment or adoption of such inconsistent provision with respect to any act or omission occurring prior to such repeal or amendment or adoption of such inconsistent provision. Our amended and restated certificate of incorporation will also permit us, to the extent and in the manner authorized or permitted by law, to indemnify and to advance expenses to persons other that those specifically covered by our amended and restated certificate of incorporation.

Our bylaws include the provisions relating to advancement of expenses and indemnification rights consistent with those which are set forth in our amended and restated certificate of incorporation. In addition, our bylaws provide for a right of indemnity to bring a suit in the event a claim for indemnification or advancement of expenses is not paid in full by us within a specified period of time. Our bylaws also permit us to purchase and maintain insurance, at our expense, to protect us and/or any director, officer, employee or agent of our corporation or another entity, trust or other enterprise against any expense, liability or loss, whether or not we would have the power to indemnify such person against such expense, liability or loss under the DGCL.

Any repeal or amendment of provisions of our bylaws affecting indemnification rights, whether by our board of directors, stockholders or by changes in applicable law, or the adoption of any other provisions inconsistent therewith, will (unless otherwise required by law) be prospective only, except to the extent such amendment or change in law permits us to provide broader indemnification rights on a retroactive basis, and will not in any way diminish or adversely affect any right or protection existing thereunder with respect to any act or omission occurring prior to such repeal or amendment or adoption of such inconsistent provision.

We have entered into indemnification agreements with each of our officers and directors, a form of which is filed as Exhibit 10.6 to our Registration Statement on

Form S-1

that was declared effective by the SEC on May 25, 2021. These agreements require us to indemnify these individuals to the fullest extent permitted under Delaware law against liabilities that may arise by reason of their service to us, and to advance expenses incurred as a result of any proceeding against them as to which they could be indemnified.

These limitations of liability do not alter director liability under the federal securities laws and do not affect the availability of equitable remedies such as an injunction or rescission.

Pursuant to the Business Combination Agreement incorporated by reference as Exhibit 2.1 to this Registration Statement, we have agreed to continue to indemnify our current directors and officers and have agreed to the continuation of director and officer liability insurance covering our current directors and officers.

It is anticipated that the board of directors of the Combined Company will, in connection with consummating the Business Combination, approve and direct the Combined Company to enter into customary

Item 22. Undertakings.

(a)

The undersigned registrant hereby undertakes:

(1)

To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i)

To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

(ii)

To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii)

To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

(2)

That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)

To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4)

That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser: each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(5)

That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities: the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i)

Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii)

Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii)

The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

II-7

Table of Contents

(iv)

Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b)(1) The undersigned registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other Items of the applicable form.

(2) The registrant undertakes that every prospectus (i) that is filed pursuant to the immediately preceding paragraph, or (ii) that purports to meet the requirements of section 10(a)(3) of the Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

(d) The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this

Form S-4,

within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

(e) The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

THIRD: The nature of the business or purposes to be conducted or promoted is to engage in any lawful act or activity for which corporations may be organized under the General Corporation Law.

FOURTH: The total number of shares of all classes of stock which the Corporation shall have authority to issue is (i) 138,000,000 shares of Common Stock, $0.0001 par value per share (“Common Stock”) and (ii) 99,734,554 shares of Preferred Stock, $0.0001 par value per share (“Preferred Stock”), 35,199,610 of which are hereby designated “Series A Preferred Stock” and 64,534,944 of which are hereby designated “Series B Preferred Stock.”

The following is a statement of the designations and the powers, privileges and rights, and the qualifications, limitations or restrictions thereof in respect of each class of capital stock of the Corporation.

COMMON STOCK

1. General. The voting, dividend and liquidation rights of the holders of the Common Stock are subject to and qualified by the rights, powers and preferences of the holders of the Preferred Stock set forth herein.

2. Voting. The holders of the Common Stock are entitled to one vote for each share of Common Stock held at all meetings of stockholders (and written actions in lieu of meetings); provided, however, that, except as otherwise required by law, holders of Common Stock, as such, shall not be entitled to vote on any amendment to the Certificate of Incorporation that relates solely to the terms of one or more outstanding series of Preferred Stock if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to the Certificate of Incorporation or pursuant to the General Corporation Law. There shall be no cumulative voting. The number of authorized shares of Common Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by (in addition to any vote of the holders of one or more series of Preferred Stock that may be required by the terms of the Certificate of Incorporation) the affirmative vote of the holders of shares of capital stock of the Corporation representing a majority of the votes represented by all outstanding shares of capital stock of the Corporation entitled to vote, irrespective of the provisions of Section 242(6)(2) of the General Corporation Law.

PREFERRED STOCK

The Preferred Stock shall have the following rights, preferences, powers, privileges and restrictions, qualifications and limitations. Unless otherwise indicated, references to “sections” or “subsections” in this Part B of this Article Fourth refer to sections and subsections of Part B of this Article Fourth.

Dividends.

(a) The holders of Series B Preferred Stock, in preference to the holders of Series A Preferred Stock and Common Stock, shall be entitled to receive, when, as and if declared by the Board of Directors of the Corporation (the “Board”), but only out of funds that are legally available therefor, cash dividends at the rate of eight percent (8%) of the applicable Original Issue Price (as defined below) per annum on each outstanding share of Series B Preferred Stock. Such dividends shall be non-cumulative.

(b) The holders of Series A Preferred Stock, in preference to the holders of Common Stock, shall be entitled to receive, when, as and if declared by the Board, but only out of funds that are legally available therefor, cash dividends at the rate of eight percent (8%) of the applicable Original Issue Price (as defined below) per annum on each outstanding share of Series A Preferred Stock. Such dividends shall be non-cumulative. The “Original Issue Price” of the Series A Preferred Stock shall mean $1.6427 per share and the “Original Issue Price” of the Series B Preferred Stock shall mean $1.6427 per share, in each case subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to such series of Preferred Stock.

(c) The Corporation shall not declare, pay or set aside any dividends on shares of any other class or series of capital stock of the Corporation unless (in addition to the obtaining of any consents required elsewhere in the Certificate of Incorporation) the Corporation has complied with Sections 1(a) and 1(b) and the holders of the Preferred Stock then outstanding shall first receive, or simultaneously receive, a dividend on each outstanding share of Preferred Stock in an amount at least equal to (i) in the case of a dividend on Common Stock or any class or series that is convertible into Common Stock, that dividend per share of Preferred Stock as would equal the product of (A) the dividend payable on each share of such class or series determined, if applicable, as if all shares of such class or series had been converted into Common Stock and (B) the number of shares of Common Stock issuable upon conversion of a share of Preferred Stock, in each case calculated on the record date for determination of holders entitled to receive such dividend or (ii) in the case of a dividend on any class or series that is not convertible into Common Stock, at a rate per share of Preferred Stock determined by (A) dividing the amount of the dividend payable on each share of such class or series of capital stock by the original issuance price of such class or series of capital stock (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to such class or series) and (B) multiplying such fraction by an amount equal to the applicable Original Issue Price; provided that, if the Corporation declares, pays or sets aside, on the same date, a dividend on shares of more than one class or series of capital stock of the Corporation, the dividend payable to the holders of Preferred Stock pursuant to this Section 1(c) shall be calculated based upon the dividend on the class or series of capital stock that would result in the highest Preferred Stock dividend.

2. Liquidation, Dissolution or Winding Up; Certain Mergers, Consolidations and Asset Sales.

2.1 Preferential Payments to Holders of Preferred Stock.

2.1.1 Preferential Payments to Holders of Series B Preferred Stock. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation or Deemed Liquidation Event, the holders of shares of Series B Preferred Stock then outstanding shall be entitled to be paid out of the assets of the Corporation available for distribution to its stockholders before any payment shall be made to the holders of the Series A Preferred Stock and Common Stock by reason of their ownership thereof, an amount per share equal to the greater of (i) the applicable Original Issue Price, plus any dividends declared but unpaid thereon, or (ii) such amount per share as would have been payable had all shares of Series B Preferred Stock been converted into Common Stock pursuant to Section 4 immediately prior to such liquidation, dissolution, winding up or Deemed Liquidation Event (the amount payable pursuant to this sentence is hereinafter referred to as the “Series B Liquidation Amount”). If upon any such liquidation, dissolution or winding up of the Corporation or Deemed Liquidation Event, the assets of the Corporation available for distribution to its stockholders shall be insufficient to pay the holders of shares of Series B Preferred Stock the full amount to which they shall be entitled under this Subsection 2.1.1, the holders of shares of Series B Preferred Stock shall share ratably in any distribution of the assets available for distribution in proportion to the respective amounts which would otherwise be payable in respect of the shares held by them upon such distribution if all amounts payable on or with respect to such shares were paid in full.

2.1.2 Preferential Payments to Holders of Series A Preferred Stock. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation or Deemed Liquidation Event, after the payment of the Series B Liquidation Amount pursuant to Subsection 2.1.1, the holders of shares of Series A Preferred Stock then outstanding shall be entitled to be paid out of the assets of the Corporation available for distribution to its stockholders before any payment shall be made to the holders of Common Stock by reason of their ownership thereof, an amount per share equal to the greater of (i) the applicable Original Issue Price, plus any dividends declared but unpaid thereon, or (ii) such amount per share as would have been payable had all shares of Series A Preferred Stock been converted into Common Stock pursuant to Section 4 immediately prior to such liquidation, dissolution, winding up or Deemed Liquidation Event (the amount payable pursuant to this sentence is hereinafter referred to as the “Series A Liquidation Amount” and, together with the Series B Liquidation Amount, the “Liquidation Amounts”, each a “Liquidation Amount”). If upon any such liquidation, dissolution or winding up of the Corporation or Deemed Liquidation Event, the assets of the Corporation available for distribution to its stockholders shall be insufficient to pay the holders of shares of Series A Preferred Stock the full amount to which they shall be entitled under this Subsection 2.1.2, the holders of shares of Series A Preferred Stock shall share ratably in any distribution of the assets available for distribution in proportion to the respective amounts which would otherwise be payable in respect of the shares held by them upon such distribution if all amounts payable on or with respect to such shares were paid in full.

2.2 Payments to Holders of Common Stock. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation or Deemed Liquidation Event, after the payment of all preferential amounts required to be paid to the holders of shares of Preferred Stock, the remaining assets of the Corporation available for distribution to its stockholders shall be distributed among the holders of shares of Common Stock, pro rata based on the number of shares held by each such holder.

2.3 Deemed Liquidation Events.

2.3.1 Definition. Each of the following events shall be considered a “Deemed Liquidation Event” unless the holders of a majority of the outstanding shares of Preferred Stock elect otherwise by written notice sent to the Corporation at least 10 days prior to the effective date of any such event:

(a) a merger or consolidation in which

(i)

the Corporation is a constituent party or

(ii)

a subsidiary of the Corporation is a constituent party and the Corporation issues shares of its capital stock pursuant to such merger or consolidation,

except any such merger or consolidation involving the Corporation or a subsidiary in which the shares of capital stock of the Corporation outstanding immediately prior to such merger or consolidation continue to represent, or are converted into or exchanged for shares of capital stock that represent, immediately following such merger or consolidation, a majority, by voting power, of the capital stock of (1) the surviving or resulting corporation; or (2) if the surviving or resulting corporation is a wholly owned subsidiary of another corporation immediately following such merger or consolidation, the parent corporation of such surviving or resulting corporation; or

(b) the sale, lease, transfer, exclusive license or other disposition, in a single transaction or series of related transactions, by the Corporation or any subsidiary of the Corporation of all or substantially all the assets of the Corporation and its subsidiaries taken as a whole, or the sale or disposition (whether by merger, consolidation or otherwise) of one or more subsidiaries of the Corporation if substantially all of the assets of the Corporation and its subsidiaries taken as a whole are held by such subsidiary or subsidiaries, except where such sale, lease, transfer, exclusive license or other disposition is to a wholly owned subsidiary of the Corporation; or

(c) the closing of the transfer by the stockholders of the Corporation (whether by merger, consolidation or otherwise), in a single transaction or series of related transactions, to a person or group of affiliated persons (other than an underwriter of the Corporation’s securities), of the Corporation’s securities if, after such closing, the stockholders of the Corporation as of immediately prior to such transaction or series of related transactions would hold less than 50% of the outstanding voting power of the Corporation (or the surviving or acquiring entity) as of immediately following such transaction or series of related transactions.

2.3.2 Effecting a Deemed Liquidation Event.

(a) The Corporation shall not have the power to effect a Deemed Liquidation Event referred to in Subsection 2.3.1(a)(i) unless the agreement or plan of merger or consolidation for such transaction (the “Merger Agreement”) provides that the consideration payable to the stockholders of the Corporation shall be allocated among the holders of capital stock of the Corporation in accordance with Subsections 2.1 and 2.2.

(b) In the event of a Deemed Liquidation Event referred to in Subsection 2.3.1(a)(ii) or 2.3.1(b), if the Corporation does not effect a dissolution of the Corporation under the General Corporation Law within ninety (90) days after such Deemed Liquidation Event, then (i) the Corporation shall send a written notice (the “Redemption Notice”) to each holder of Preferred Stock no later than the ninetieth (90th) day after the Deemed Liquidation Event advising such holders of their right (and the requirements to be met to secure such right) pursuant to the terms of the following clause; (ii) to require the redemption of such shares of Preferred Stock, and (iii) if the holders of a majority of the then outstanding shares of Preferred Stock so request in a written instrument delivered to the Corporation not later than one hundred twenty (120) days after such Deemed Liquidation Event, the Corporation shall use the consideration received by the Corporation for such Deemed Liquidation Event (net of any retained liabilities associated with the assets sold or technology licensed, as determined in good faith by the Board), together with any other assets of the Corporation available for distribution to its stockholders, all to the extent permitted by Delaware law governing distributions to stockholders (the “Available Proceeds”), on the one hundred fiftieth (150^th) day after such Deemed Liquidation Event, to redeem all outstanding shares of Preferred Stock at a price per share equal to the applicable Liquidation Amount. Notwithstanding the foregoing, in the event of a redemption pursuant to the preceding sentence, if the Available Proceeds are not sufficient to redeem all outstanding shares of Preferred Stock, the Corporation shall ratably redeem each holder’s shares of Preferred Stock to the fullest extent of such Available Proceeds, and shall redeem the remaining shares as soon as it may lawfully do so under Delaware law governing distributions to stockholders. Prior to the distribution or redemption provided for in this Subsection 2.3.2(b), the Corporation shall not expend or dissipate the consideration received for such Deemed Liquidation Event, except to discharge expenses incurred in connection with such Deemed Liquidation Event or in the ordinary course of business.

(i) Each Redemption Notice shall state: (1) the number of shares of Preferred Stock held by the holder that the Corporation shall redeem; (2) the date of redemption (the “Redemption Date”) and the amount to be paid to such holder; and (3) for holders of shares in certificated form, that the holder is to surrender to the Corporation, in the manner and at the place designated, his, her or its certificate or certificates representing the shares of Preferred Stock to be redeemed.

(ii) On or before the Redemption Date, each holder of shares of Preferred Stock to be redeemed shall surrender the certificate or certificates representing such shares (or, if such registered holder alleges that such certificate has been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to the Corporation to indemnify the Corporation against any claim that may be made against the Corporation on account of the alleged loss, theft or destruction of such certificate) to the Corporation, in the manner and at the place designated in the Redemption Notice, and thereupon the Available Proceeds for such shares shall be payable to the order of the person whose name appears on such certificate or certificates as the owner thereof.

2.3.3 Amount Deemed Paid or Distributed. The amount deemed paid or distributed to the holders of capital stock of the Corporation upon any such merger, consolidation, sale, transfer, exclusive license, other disposition or redemption shall be the cash or the value of the property, rights or securities paid or distributed to such holders by the Corporation or the acquiring person, firm or other entity. The value of such property, rights or securities shall be determined in good faith by the Board, including the Requisite Preferred Directors (as defined below).

2.3.4 Allocation of Escrow and Contingent Consideration. In the event of a Deemed Liquidation Event pursuant to Subsection 2.3.1(a)(i), if any portion of the consideration payable to the stockholders of the Corporation is payable only upon satisfaction of contingencies (the “Additional Consideration”), the Merger Agreement shall provide that (a) the portion of such consideration that is not Additional Consideration (such portion, the “Initial Consideration”) shall be allocated among the holders of capital stock of the Corporation in accordance with Subsections 2.1 and 2.2 as if the Initial Consideration were the only consideration payable in connection with such Deemed Liquidation Event; and (b) any Additional Consideration which becomes payable to the stockholders of the Corporation upon release from escrow or satisfaction of such contingencies shall be allocated among the holders of capital stock of the Corporation in accordance with Subsections 2.1 and 2.2 after taking into account the previous payment of the Initial Consideration as part of the same transaction. For the purposes of this Subsection 2.3.4, consideration placed into escrow or retained as holdback to be available for satisfaction of indemnification or similar obligations in connection with such Deemed Liquidation Event shall be deemed to be Additional Consideration.

3. Voting.

3.1 General. On any matter presented to the stockholders of the Corporation for their action or consideration at any meeting of stockholders of the Corporation (or by written consent of stockholders in lieu of meeting), each holder of outstanding shares of Preferred Stock shall be entitled to cast the number of votes equal to the number of whole shares of Common Stock into which the shares of Preferred Stock held by such holder are convertible as of the record date for determining stockholders entitled to vote on such matter. Except as provided by law or by the other provisions of the Certificate of Incorporation, holders of Preferred Stock shall vote together with the holders of Common Stock as a single class.

3.2 Election of Directors. The holders of record of the shares of Series A Preferred Stock, exclusively and as a separate class, shall be entitled to elect two (2) directors of the Corporation (the “Series A Directors”), the holders of record of the shares of Series B Preferred Stock, exclusively and as a separate class, shall be entitled to elect two (2) directors of the Corporation (the “Series B Directors” and, together with the Series A Directors, the “Preferred Directors”) and the holders of record of the shares of Common Stock, exclusively and as a separate class, shall be entitled to elect two (2) directors of the Corporation. Any director elected as provided in the preceding sentence may be removed without cause by, and only by, the affirmative vote of the holders of the shares of the class or series of capital stock entitled to elect such director or directors, given either at a special meeting of such stockholders duly called for that purpose or pursuant to a written consent of stockholders. If the holders of shares of the applicable series of Preferred Stock or Common Stock, as the case may be, fail to elect a sufficient number of directors to fill all directorships for which they are entitled to elect directors, voting exclusively and as a separate class, pursuant to the first sentence of this Subsection 3.2, then any directorship not so filled shall remain vacant until such time as the holders of the applicable series of Preferred Stock or Common Stock, as the case may be, elect a person to fill such directorship by vote or written consent in lieu of a meeting; and no such directorship may be filled by stockholders of the Corporation other than by the stockholders of the Corporation that are entitled to elect a person to fill such directorship, voting exclusively and as a separate class, provided, however, that for administrative convenience, in connection with the approval of the initial issuance of Series B Preferred Stock, the Series B Directors may also be appointed by the Board without a separate action by the holders of Series B Preferred Stock. The holders of record of the shares of Common Stock and of any other class or series of voting stock (including the Preferred Stock), exclusively and voting together as a single class, shall be entitled to elect the balance of the total number of directors of the Corporation. At any meeting held for the purpose of electing a director, the presence in person or by proxy of the holders of a majority of the outstanding shares of the class or series entitled to elect such director shall constitute a quorum for the purpose of electing such director. Except as otherwise provided in this Subsection 3.2, a vacancy in any directorship filled by the holders of any class or series shall be filled only by vote or written consent in lieu of a meeting of the holders of such class or series or by any remaining director or directors elected by the holders of such class or series pursuant to this Subsection 3.2.

3.3 Protective Provisions

3.3.1 Preferred Stock Protective Provisions. At any time when any shares of Preferred Stock are outstanding, the Corporation shall not, either directly or indirectly by amendment, merger, recapitalization, consolidation or otherwise, do any of the following without (in addition to any other vote required by law or the Certificate of Incorporation) the written consent or affirmative vote of the holders of a majority of the then outstanding shares of Preferred Stock, given in writing or by vote at a meeting, consenting or voting (as the case may be) together as a single class, and any such act or transaction entered into without such consent or vote shall be null and void ab initio, and of no force or effect:

(a) liquidate, dissolve or wind-up the business and affairs of the Corporation, effect any merger or consolidation or any other Deemed Liquidation Event, reclassify or recapitalize the outstanding capital stock of the Corporation, or consent, agree or commit to any of the foregoing without conditioning such consent, agreement or commitment upon obtaining the approval required by this Section 3.3.1(a);

(b) amend, alter or repeal any provision of the Certificate of Incorporation or Bylaws of the Corporation;

(d) create, designate or authorize the creation of, or issue or obligate itself to issue, whether by reclassification or otherwise, any additional class or series of capital stock or any other equity security or debt security convertible into equity securities of the Corporation unless the same ranks junior to the Series B Preferred Stock with respect to the distribution of assets on the liquidation, dissolution or winding up of the Corporation, the payment of dividends, voting rights and rights of redemption, or increase the authorized number of shares of any such additional class or series of capital stock unless the same ranks junior to the Series B Preferred Stock with respect to the distribution of assets on the liquidation, dissolution or winding up of the Corporation, the payment of dividends, voting rights and rights of redemption;

(e) reclassify, alter or amend any existing security of the Corporation, if such reclassification, alteration or amendment would render such other security on a parity with or senior to the Series B Preferred Stock in respect of the distribution of assets on the liquidation, dissolution or winding up of the Corporation, the payment of dividends, voting rights and rights of redemption;

(f) purchase or redeem (or permit any subsidiary to purchase or redeem) or pay or declare any dividend or make any distribution on, any shares of capital stock of the Corporation other than (i) redemptions of or dividends or distributions on the Preferred Stock as expressly authorized herein, (ii) dividends or other distributions payable on the Common Stock solely in the form of additional shares of Common Stock and (iii) repurchases of stock from former employees, officers, directors, consultants or other persons who performed services for the Corporation or any subsidiary in connection with the cessation of such employment or service at the lower of the original purchase price or the then-current fair market value thereof;

(g) unless approved by the Board, including at least a majority of the Preferred Directors then serving (the “Requisite Preferred Directors”), (i) incur indebtedness for borrowed money, (ii) guarantee, directly or indirectly, any indebtedness, or (iii) make any loans to other persons or entities (other than intercompany loans between the Corporation and any wholly owned subsidiary or between wholly owned subsidiaries of the Corporation), in each case, in excess of $500,000;

(h) unless approved by the Board, including the Requisite Preferred Directors, (i) create, or hold capital stock in, any subsidiary that is not wholly owned (either directly or through one or more other subsidiaries) by the Corporation, (ii) sell, transfer or otherwise dispose of any capital stock of any direct or indirect subsidiary of the Corporation, or (iii) permit any direct or indirect subsidiary to sell, lease, transfer, exclusively license or otherwise dispose (in a single transaction or series of related transactions) of all or substantially all of the assets of such subsidiary;

(i) consummate a bona fide acquisition of another entity by the Corporation by merger or consolidation with such other entity, or purchase all or substantially all of the assets of, or purchase more than fifty percent (50%) of the outstanding equity securities of, another entity (each, an “Acquisition”);

(j) enter into a sale, transfer, license, pledge or encumbrance of technology or intellectual property, other than licenses arising in the ordinary course of business, unless approved by the Board, including the Requisite Preferred Directors;

(k) increase or decrease the authorized number of, or alter the method of selecting members of, the Board;

(l) unless approved by the Board, including the Requisite Preferred Directors, enter into or be a party to, or permit any subsidiary to enter into or be a party to, any transaction with any director, officer or employee of the Corporation or its subsidiaries, or any “associate” (as defined in Rule 12b-2 promulgated under the Exchange Act of 1934, as amended) of any of the foregoing persons;

(m) enter into any corporate strategic relationship or joint venture involving the payment, contribution or assignment by the Corporation or to the Corporation of assets greater than $500,000, unless approved by the Board, including the Requisite Preferred Directors; or

(n) change the principal business of the Corporation, enter new lines of business or exit the current line of business, unless, in each case, approved by the Board, including the Requisite Preferred Directors.

Notwithstanding the foregoing, in the event that a majority of the outstanding shares of Preferred Stock are converted to Common Stock pursuant to a Special Mandatory Conversion (as defined below), Subsections 3.3.1(b), (c) and (d) shall not apply with respect to sales of Preferred Stock by the Corporation following such Special Mandatory Conversion.

3.4 Series Protective Provisions. For so long as at least 25% of the originally issued shares of a series of Preferred Stock are outstanding, the Corporation shall not, either directly or indirectly by amendment, merger, recapitalization, consolidation or otherwise, do any of the following without (in addition to any other vote required by law or the Certificate of Incorporation) the written consent or affirmative vote of the holders of a majority of the then outstanding shares of such series of Preferred Stock, given in writing or by vote at a meeting, consenting or voting (as the case may be) separately as a class, and any such act or transaction entered into without such consent or vote shall be null and void ab initio, and of no force or effect:

(a) amend, alter or repeal any provision of the Certificate of Incorporation or the Bylaws of the Corporation in a manner that adversely and disproportionately affects such series of Preferred Stock (it being understood that a series of Preferred Stock shall not be disproportionately affected because of proportional differences in the amounts of respective issue prices, liquidation preferences and redemption prices that arise out of differences in the original issue price vis-à-vis other series of Preferred Stock); or

(b) increase the authorized number of shares of such series of Preferred Stock.

4. Optional Conversion.

The holders of the Preferred Stock shall have conversion rights as follows (the “Conversion Rights”):

4.1 Right to Convert.

4.1.1 Conversion Ratio. Each share of Preferred Stock shall be convertible, at the option of the holder thereof, at any time and from time to time, and without the payment of additional consideration by the holder thereof, into such number of fully paid and non-assessable shares of Common Stock as is determined by dividing the applicable Original Issue Price by the applicable Conversion Price (as defined below) in effect at the time of conversion. The “Conversion Price” shall initially be equal to the applicable Original Issue Price of such series. Such initial Conversion Price, and the rate at which shares of Preferred Stock may be converted into shares of Common Stock, shall be subject to adjustment as provided below.

4.1.2 Termination of Conversion Rights. In the event of a liquidation, dissolution or winding up of the Corporation or a Deemed Liquidation Event, the Conversion Rights shall terminate at the close of business on the last full day preceding the date fixed for the payment of any such amounts distributable on such event to the holders of Preferred Stock.

4.2 Fractional Shares. No fractional shares of Common Stock shall be issued upon conversion of the Preferred Stock. In lieu of any fractional shares to which the holder would otherwise be entitled, the Corporation shall pay cash equal to such fraction multiplied by the fair market value of a share of Common Stock as determined in good faith by the Board, including the Requisite Preferred Directors. Whether or not fractional shares would be issuable upon such conversion shall be determined on the basis of the total number of shares of Preferred Stock the holder is at the time converting into Common Stock and the aggregate number of shares of Common Stock issuable upon such conversion.

4.3 Mechanics of Conversion.

4.3.1 Notice of Conversion. In order for a holder of Preferred Stock to voluntarily convert shares of Preferred Stock into shares of Common Stock, such holder shall (a) provide written notice to the Corporation’s transfer agent at the office of the transfer agent for the Preferred Stock (or at the principal office of the Corporation if the Corporation serves as its own transfer agent) that such holder elects to convert all or any number of such holder’s shares of Preferred Stock and, if applicable, any event on which such conversion is contingent and (b), if such holder’s shares are certificated, surrender the certificate or certificates for such shares of Preferred Stock (or, if such registered holder alleges that such certificate has been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to the Corporation to indemnify the Corporation against any claim that may be made against the Corporation on account of the alleged loss, theft or destruction of such certificate), at the office of the transfer agent for the Preferred Stock (or at the principal office of the Corporation if the Corporation serves as its own transfer agent). Such notice shall state such holder’s name or the names of the nominees in which such holder wishes the shares of Common Stock to be issued. If required by the Corporation, any certificates surrendered for conversion shall be endorsed or accompanied by a written instrument or instruments of transfer, in form satisfactory to the Corporation, duly executed by the registered holder or his, her or its attorney duly authorized in writing. The close of business on the date of receipt by the transfer agent (or by the Corporation if the Corporation serves as its own transfer agent) of such notice and, if applicable, certificates (or lost certificate affidavit and agreement) shall be the time of conversion (the “Conversion Time”), and the shares of Common Stock issuable upon conversion of the specified shares shall be deemed to be outstanding of record as of such date. The Corporation shall, as soon as practicable after the Conversion Time (i) issue and deliver to such holder of Preferred Stock, or to his, her or its nominees, a certificate or certificates for the number of full shares of Common Stock issuable upon such conversion in accordance with the provisions hereof and a certificate for the number (if any) of the shares of Preferred Stock represented by the surrendered certificate that were not converted into Common Stock, (ii) pay in cash such amount as provided in Subsection 4.2 in lieu of any fraction of a share of Common Stock otherwise issuable upon such conversion and (iii) pay all declared but unpaid dividends on the shares of Preferred Stock converted.

4.3.2 Reservation of Shares. The Corporation shall at all times when the Preferred Stock shall be outstanding, reserve and keep available out of its authorized but unissued capital stock, for the purpose of effecting the conversion of the Preferred Stock, such number of its duly authorized shares of Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding Preferred Stock; and if at any time the number of authorized but unissued shares of Common Stock shall not be sufficient to effect the conversion of all then outstanding shares of the Preferred Stock, the Corporation shall take such corporate action as may be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purposes, including, without limitation, engaging in best efforts to obtain the requisite stockholder approval of any necessary amendment to the Certificate of Incorporation. Before taking any action which would cause an adjustment reducing the applicable Conversion Price below the then par value of the shares of Common Stock issuable upon conversion of such series of Preferred Stock, the Corporation will take any corporate action which may, in the opinion of its counsel, be necessary in order that the Corporation may validly and legally issue fully paid and non-assessable shares of Common Stock at such adjusted applicable Conversion Price.

4.3.3 Effect of Conversion. All shares of Preferred Stock which shall have been surrendered for conversion as herein provided shall no longer be deemed to be outstanding and all rights with respect to such shares shall immediately cease and terminate at the Conversion Time, except only the right of the holders thereof to receive shares of Common Stock in exchange therefor, to receive payment in lieu of any fraction of a share otherwise issuable upon such conversion as provided in Subsection 4.2 and to receive payment of any dividends declared but unpaid thereon. Any shares of Preferred Stock so converted shall be retired and cancelled and may not be reissued as shares of such series, and the Corporation may thereafter take such appropriate action (without the need for stockholder action) as may be necessary to reduce the authorized number of shares of Preferred Stock accordingly.

4.3.4 No Further Adjustment. Upon any such conversion, no adjustment to the applicable Conversion Price shall be made for any declared but unpaid dividends on the Preferred Stock surrendered for conversion or on the Common Stock delivered upon conversion.

4.3.5 Taxes. The Corporation shall pay any and all issue and other similar taxes that may be payable in respect of any issuance or delivery of shares of Common Stock upon conversion of shares of Preferred Stock pursuant to this Section 4. The Corporation shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of shares of Common Stock in a name other than that in which the shares of Preferred Stock so converted were registered, and no such issuance or delivery shall be made unless and until the person or entity requesting such issuance has paid to the Corporation the amount of any such tax or has established, to the satisfaction of the Corporation, that such tax has been paid.

4.4 Adjustments to Applicable Conversion Price for Diluting Issues.

(iv)

4.4.2 No Adjustment of Applicable Conversion Price. No adjustment in the applicable Conversion Price shall be made as the result of the issuance or deemed issuance of Additional Shares of Common Stock if the Corporation receives written notice from the holders of a majority of the then outstanding shares of Preferred Stock agreeing that no such adjustment shall be made as the result of the issuance or deemed issuance of such Additional Shares of Common Stock.

4.4.3 Deemed Issue of Additional Shares of Common Stock.

(a) If the Corporation at any time or from time to time after the Original Issue Date shall issue any Options or Convertible Securities (excluding Options or Convertible Securities which are themselves Exempted Securities) or shall fix a record date for the determination of holders of any class of securities entitled to receive any such Options or Convertible Securities, then the maximum number of shares of Common Stock (as set forth in the instrument relating thereto, assuming the satisfaction of any conditions to exercisability, convertibility or exchangeability but without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or, in the case of Convertible Securities and Options therefor, the conversion or exchange of such Convertible Securities, shall be deemed to be Additional Shares of Common Stock issued as of the time of such issue or, in case such a record date shall have been fixed, as of the close of business on such record date.

(b) If the terms of any Option or Convertible Security, the issuance of which resulted in an adjustment to the applicable Conversion Price pursuant to the terms of Subsection 4.4.4, are revised as a result of an amendment to such terms or any other adjustment pursuant to the provisions of such Option or Convertible Security (but excluding automatic adjustments to such terms pursuant to anti-dilution or similar provisions of such Option or Convertible Security) to provide for either (1) any increase or decrease in the number of shares of Common Stock issuable upon the exercise, conversion and/or exchange of any such Option or Convertible Security or (2) any increase or decrease in the consideration payable to the Corporation upon such exercise, conversion and/or exchange, then, effective upon such increase or decrease becoming effective, the applicable Conversion Price computed upon the original issue of such Option or Convertible Security (or upon the occurrence of a record date with respect thereto) shall be readjusted to such applicable Conversion Price as would have obtained had such revised terms been in effect upon the original date of issuance of such Option or Convertible Security. Notwithstanding the foregoing, no readjustment pursuant to this clause (b) shall have the effect of increasing the applicable Conversion Price to an amount which exceeds the lower of (i) the applicable Conversion Price in effect immediately prior to the original adjustment made as a result of the issuance of such Option or Convertible Security, or (ii) the applicable Conversion Price that would have resulted from any issuances of Additional Shares of Common Stock (other than deemed issuances of Additional Shares of Common Stock as a result of the issuance of such Option or Convertible Security) between the original adjustment date and such readjustment date.

(c) If the terms of any Option or Convertible Security (excluding Options or Convertible Securities which are themselves Exempted Securities), the issuance of which did not result in an adjustment to the applicable Conversion Price pursuant to the terms of Subsection 4.4.4 (either because the consideration per share (determined pursuant to Subsection 4.4.5) of the Additional Shares of Common Stock subject thereto was equal to or greater than the applicable Conversion Price then in effect, or because such Option or Convertible Security was issued before the applicable Original Issue Date), are revised after the Original Issue Date as a result of an amendment to such terms or any other adjustment pursuant to the provisions of such Option or Convertible Security (but excluding automatic adjustments to such terms pursuant to anti-dilution or similar provisions of such Option or Convertible Security) to provide for either (1) any increase in the number of shares of Common Stock issuable upon the exercise, conversion or exchange of any such Option or Convertible Security or (2) any decrease in the consideration payable to the Corporation upon such exercise, conversion or exchange, then such Option or Convertible Security, as so amended or adjusted, and the Additional Shares of Common Stock subject thereto (determined in the manner provided in Subsection 4.4.3(a) shall be deemed to have been issued effective upon such increase or decrease becoming effective.

(d) Upon the expiration or termination of any unexercised Option or unconverted or unexchanged Convertible Security (or portion thereof) which resulted (either upon its original issuance or upon a revision of its terms) in an adjustment to the applicable Conversion Price pursuant to the terms of Subsection 4.4.4, the applicable Conversion Price shall be readjusted to such applicable Conversion Price as would have obtained had such Option or Convertible Security (or portion thereof) never been issued.

(e) If the number of shares of Common Stock issuable upon the exercise, conversion and/or exchange of any Option or Convertible Security, or the consideration payable to the Corporation upon such exercise, conversion and/or exchange, is calculable at the time such Option or Convertible Security is issued or amended but is subject to adjustment based upon subsequent events, any adjustment to the applicable Conversion Price provided for in this Subsection 4.4.3 shall be effected at the time of such issuance or amendment based on such number of shares or amount of consideration without regard to any provisions for subsequent adjustments (and any subsequent adjustments shall be treated as provided in clauses (b) and (c) of this Subsection 4.4.3). If the number of shares of Common Stock issuable upon the exercise, conversion and/or exchange of any Option or Convertible Security, or the consideration payable to the Corporation upon such exercise, conversion and/or exchange, cannot be calculated at all at the time such Option or Convertible Security is issued or amended, any adjustment to the applicable Conversion Price that would result under the terms of this Subsection 4.4.3 at the time of such issuance or amendment shall instead be effected at the time such number of shares and/or amount of consideration is first calculable (even if subject to subsequent adjustments), assuming for purposes of calculating such adjustment to the applicable Conversion Price that such issuance or amendment took place at the time such calculation can first be made.

4.4.4 Adjustment of Applicable Conversion Price Upon Issuance of Additional Shares of Common Stock. In the event the Corporation shall at any time after the Original Issue Date issue Additional Shares of Common Stock (including Additional Shares of Common Stock deemed to be issued pursuant to Subsection 4.4.3), without consideration or for a consideration per share less than the applicable Conversion Price in effect immediately prior to such issue, then the applicable Conversion Price shall be reduced, concurrently with such issue, to a price (calculated to the nearest one-hundredth of a cent) determined in accordance with the following formula:

CP₂ = CP₁* (A + B) / (A + C).

For purposes of the foregoing formula, the following definitions shall apply:

(a) “CP₂” shall mean the applicable Conversion Price in effect immediately after such issue of Additional Shares of Common Stock

(b) “CP₁” shall mean the applicable Conversion Price in effect immediately prior to such issue of Additional Shares of Common Stock;

(c) “A” shall mean the number of shares of Common Stock outstanding immediately prior to such issue of Additional Shares of Common Stock (treating for this purpose as outstanding all shares of Common Stock issuable upon exercise of Options outstanding immediately prior to such issue or upon conversion or exchange of Convertible Securities (including the Preferred Stock) outstanding (assuming exercise of any outstanding Options therefor) immediately prior to such issue);

(d) “B” shall mean the number of shares of Common Stock that would have been issued if such Additional Shares of Common Stock had been issued at a price per share equal to CP₁ (determined by dividing the aggregate consideration received by the Corporation in respect of such issue by CP); and

(e) “C” shall mean the number of such Additional Shares of Common Stock issued in such transaction.

4.4.5 Determination of Consideration. For purposes of this Subsection 4.4 the consideration received by the Corporation for the issue of any Additional Shares of Common Stock shall be computed as follows:

(a) Cash and Property: Such consideration shall:

(i)

insofar as it consists of cash, be computed at the aggregate amount of cash received by the Corporation, excluding amounts paid or payable for accrued interest;

(ii)

insofar as it consists of property other than cash, be computed at the fair market value thereof at the time of such issue, as determined in good faith by the Board; and

(iii)

in the event Additional Shares of Common Stock are issued together with other shares or securities or other assets of the Corporation for consideration which covers both, be the proportion of such consideration so received, computed as provided in clauses (i) and (ii) above, as determined in good faith by the Board.

(b) Options and Convertible Securities. The consideration per share received by the Corporation for Additional Shares of Common Stock deemed to have been issued pursuant to Subsection 4.4.3, relating to Options and Convertible Securities, shall be determined by dividing:

(i)

The total amount, if any, received or receivable by the Corporation as consideration for the issue of such Options or Convertible Securities, plus the minimum aggregate amount of additional consideration (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such consideration) payable to the Corporation upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities, by

(ii)

the maximum number of shares of Common Stock (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities.

4.4.6 Multiple Closing Dates. In the event the Corporation shall issue on more than one date Additional Shares of Common Stock that are a part of one transaction or a series of related transactions and that would result in an adjustment to the applicable Conversion Price pursuant to the terms of Subsection 4.4.4 then, upon the final such issuance, the applicable Conversion Price shall be readjusted to give effect to all such issuances as if they occurred on the date of the first such issuance (and without giving effect to any additional adjustments as a result of any such subsequent issuances within such period).

4.5 Adjustment for Stock Splits and Combinations. If the Corporation shall at any time or from time to time after the Original Issue Date effect a subdivision of the outstanding Common Stock, the applicable Conversion Price in effect immediately before that subdivision shall be proportionately decreased so that the number of shares of Common Stock issuable on conversion of each share of such series shall be increased in proportion to such increase in the aggregate number of shares of Common Stock outstanding. If the Corporation shall at any time or from time to time after the Original Issue Date combine the outstanding shares of Common Stock, the applicable Conversion Price in effect immediately before the combination shall be proportionately increased so that the number of shares of Common Stock issuable on conversion of each share of such series shall be decreased in proportion to such decrease in the aggregate number of shares of Common Stock outstanding. Any adjustment under this subsection shall become effective at the close of business on the date the subdivision or combination becomes effective.

4.6 Adjustment for Certain Dividends and Distributions. In the event the Corporation at any time or from time to time after the Original Issue Date shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable on the Common Stock in additional shares of Common Stock, then and in each such event the applicable Conversion Price in effect immediately before such event shall be decreased as of the time of such issuance or, in the event such a record date shall have been fixed, as of the close of business on such record date, by multiplying the applicable Conversion Price then in effect by a fraction:

(1) the numerator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date, and

(2) the denominator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of shares of Common Stock issuable in payment of such dividend or distribution.

Notwithstanding the foregoing (a) if such record date shall have been fixed and such dividend is not fully paid or if such distribution is not fully made on the date fixed therefor, the applicable Conversion Price shall be recomputed accordingly as of the close of business on such record date and thereafter the applicable Conversion Price shall be adjusted pursuant to this subsection as of the time of actual payment of such dividends or distributions; and (b) that no such adjustment shall be made if the holders of Preferred Stock simultaneously receive a dividend or other distribution of shares of Common Stock in a number equal to the number of shares of Common Stock as they would have received if all outstanding shares of Preferred Stock had been converted into Common Stock on the date of such event.

4.7 Adjustments for Other Dividends and Distributions. In the event the Corporation at any time or from time to time after the Original Issue Date shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in securities of the Corporation (other than a distribution of shares of Common Stock in respect of outstanding shares of Common Stock) or in other property and the provisions of Section 1 do not apply to such dividend or distribution, then and in each such event the holders of Preferred Stock shall receive, simultaneously with the distribution to the holders of Common Stock, a dividend or other distribution of such securities or other property in an amount equal to the amount of such securities or other property as they would have received if all outstanding shares of such series of Preferred Stock had been converted into Common Stock on the date of such event.

4.8 Adjustment for Merger or Reorganization etc. Subject to the provisions of Subsection 2.3, if there shall occur any reorganization, recapitalization, reclassification, consolidation or merger involving the Corporation in which the Common Stock (but not the Preferred Stock) is converted into or exchanged for securities, cash or other property (other than a transaction covered by Subsections 4.4, 4.6 or 4.7) then, following any such reorganization, recapitalization, reclassification, consolidation or merger, each share of Preferred Stock shall thereafter be convertible in lieu of the Common Stock into which it was convertible prior to such event into the kind and amount of securities, cash or other property which a holder of the number of shares of Common Stock of the Corporation issuable upon conversion of one share of Preferred Stock immediately prior to such reorganization, recapitalization, reclassification, consolidation or merger would have been entitled to receive pursuant to such transaction; and, in such case, appropriate adjustment (as determined in good faith by the Board) shall be made in the application of the provisions in this Section 4 with respect to the rights and interests thereafter of the holders of the Preferred Stock, to the end that the provisions set forth in this Section 4 (including provisions with respect to changes in and other adjustments of the applicable Conversion Price) shall thereafter be applicable, as nearly as reasonably may be, in relation to any securities or other property thereafter deliverable upon the conversion of the Preferred Stock.

4.9 Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment of the applicable Conversion Price pursuant to this Section 4 the Corporation at its expense shall, as promptly as reasonably practicable but in any event not later than ten (10) days thereafter, compute such adjustment or readjustment in accordance with the terms hereof and furnish to each holder of Preferred Stock a certificate setting forth such adjustment or readjustment (including the kind and amount of securities, cash or other property into which the Preferred Stock is convertible) and showing in detail the facts upon which such adjustment or readjustment is based. The Corporation shall, as promptly as reasonably practicable after the written request at any time of any holder of Preferred Stock (but in any event not later than ten (10) days thereafter), furnish or cause to be furnished to such holder a certificate setting forth (i) the applicable Conversion Price then in effect, and (ii) the number of shares of Common Stock and the amount, if any, of other securities, cash or property which then would be received upon the conversion of such series of Preferred Stock.

4.10 Notice of Record Date. In the event:

(a) the Corporation shall take a record of the holders of its Common Stock (or other capital stock or securities at the time issuable upon conversion of the Preferred Stock) for the purpose of entitling or enabling them to receive any dividend or other distribution, or to receive any right to subscribe for or purchase any shares of capital stock of any class or any other securities, or to receive any other security; or

(b) of any capital reorganization of the Corporation, any reclassification of the Common Stock of the Corporation, or any Deemed Liquidation Event; or

then, and in each such case, the Corporation will send or cause to be sent to the holders of the Preferred Stock a notice specifying, as the case may be, (i) the record date for such dividend, distribution or right, and the amount and character of such dividend, distribution or right, or (ii) the effective date on which such reorganization, reclassification, consolidation, merger, transfer, dissolution, liquidation or winding-up is proposed to take place, and the time, if any is to be fixed, as of which the holders of record of Common Stock (or such other capital stock or securities at the time issuable upon the conversion of such series of Preferred Stock) shall be entitled to exchange their shares of Common Stock (or such other capital stock or securities) for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, transfer, dissolution, liquidation or winding-up, and the amount per share and character of such exchange applicable to such series of Preferred Stock and the Common Stock. Such notice shall be sent at least ten (10) days prior to the record date or effective date for the event specified in such notice.

5. Mandatory Conversion.

5.1 Trigger Events. Upon either (a) the closing of the sale of shares of Common Stock to the public at a price of at least $4.9281 per share (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to the Common Stock), in a firm-commitment underwritten public offering pursuant to an effective registration statement under the Securities Act of 1933, as amended, resulting in at least $50 million of proceeds, net of the underwriting discount and commissions, to the Corporation (a “QPO”) or (b) the date and time, or the occurrence of an event, specified by vote or written consent of the holders of a majority of the then outstanding shares of Preferred Stock (the time of such closing or the date and time specified or the time of the event specified in such vote or written consent is referred to herein as the “Mandatory Conversion Time”), then (i) all outstanding shares of Preferred Stock shall automatically be converted into shares of Common Stock, at the then effective conversion rate as calculated pursuant to Subsection 4.1.1 and (ii) such shares may not be reissued by the Corporation.

5.2 Procedural Requirements. All holders of record of shares of Preferred Stock shall be sent written notice of the Mandatory Conversion Time and the place designated for mandatory conversion of all such shares of Preferred Stock pursuant to this Section 5. Such notice need not be sent in advance of the occurrence of the Mandatory Conversion Time. Upon receipt of such notice, each holder of shares of Preferred Stock in certificated form shall surrender his, her or its certificate or certificates for all such shares (or, if such holder alleges that such certificate has been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to the Corporation to indemnify the Corporation against any claim that may be made against the Corporation on account of the alleged loss, theft or destruction of such certificate) to the Corporation at the place designated in such notice. If so required by the Corporation, any certificates surrendered for conversion shall be endorsed or accompanied by written instrument or instruments of transfer, in form satisfactory to the Corporation, duly executed by the registered holder or by his, her or its attorney duly authorized in writing. All rights with respect to the Preferred Stock converted pursuant to Subsection 5.1, including the rights, if any, to receive notices and vote (other than as a holder of Common Stock), will terminate at the Mandatory Conversion Time (notwithstanding the failure of the holder or holders thereof to surrender any certificates at or prior to such time), except only the rights of the holders thereof, upon surrender of any certificate or certificates of such holders (or lost certificate affidavit and agreement) therefor, to receive the items provided for in the next sentence of this Subsection 5.2. As soon as practicable after the Mandatory Conversion Time and, if applicable, the surrender of any certificate or certificates (or lost certificate affidavit and agreement) for Preferred Stock, the Corporation shall (a) issue and deliver to such holder, or to his, her or its nominees, a certificate or certificates for the number of full shares of Common Stock issuable on such conversion in accordance with the provisions hereof and (b) pay cash as provided in Subsection 4.2 in lieu of any fraction of a share of Common Stock otherwise issuable upon such conversion and the payment of any declared but unpaid dividends on the shares of Preferred Stock converted. Such converted Preferred Stock shall be retired and cancelled and may not be reissued as shares of such series, and the Corporation may thereafter take such appropriate action (without the need for stockholder action) as may be necessary to reduce the authorized number of shares of Preferred Stock accordingly.

5A. Special Mandatory Conversion.

5A.1. Trigger Event. In the event that any holder of shares of Series B Preferred Stock fails to fulfill its entire obligation to participate in a Milestone Closing (as defined below) by purchasing such holder’s Designated Amount (as defined below) at or prior to the applicable Milestone Closing, then each share of Series B Preferred Stock held by such holder shall automatically, and without any further action on the part of such holder, be converted into shares of Common Stock at the applicable Conversion Price in effect immediately prior to such Milestone Closing, effective upon, subject to, and concurrently with, such Milestone Closing. For purposes of determining whether a holder of Series B Preferred Stock has purchased its Designated Amount at the applicable Milestone Closing, all shares of Series B Preferred Stock purchased by Affiliates (as defined below) of such holder at such Milestone Closing shall be aggregated with the shares of Series B Preferred Stock purchased by such holder at such Milestone Closing (provided that no shares or securities shall be attributed to more than one entity or person within any such group of affiliated entities or persons). Such conversion is referred to as a “Special Mandatory Conversion.”

5A.2. Procedural Requirements. Upon a Special Mandatory Conversion, each holder of shares of Series B Preferred Stock converted pursuant to Subsection 5A.1 shall be sent written notice of such Special Mandatory Conversion and the place designated for mandatory conversion of all such shares of Series B Preferred Stock pursuant to this Section 5A. Upon receipt of such notice, each holder of such shares of Series B Preferred Stock in certificated form shall surrender his, her or its certificate or certificates for all such shares (or, if such holder alleges that any such certificate has been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to the Corporation to indemnify the Corporation against any claim that may be made against the Corporation on account of the alleged loss, theft or destruction of such certificate) to the Corporation at the place designated in such notice. If so required by the Corporation, any certificates surrendered for conversion shall be endorsed or accompanied by written instrument or instruments of transfer, in form satisfactory to the Corporation, duly executed by the registered holder or by his, her or its attorney duly authorized in writing. All rights with respect to the Series B Preferred Stock converted pursuant to Subsection 5A.1, including the rights, if any, to receive notices and vote (other than as a holder of Common Stock), will terminate at the time of the Special Mandatory Conversion (notwithstanding the failure of the holder or holders thereof to surrender any certificates for such shares at or prior to such time), except only the rights of the holders thereof, upon surrender of any certificate or certificates of such holders therefor (or lost certificate affidavit and agreement), to receive the items provided for in the next sentence of this Subsection 5A.2. As soon as practicable after the Special Mandatory Conversion and, if applicable, the surrender of any certificate or certificates (or lost certificate affidavit and agreement) for Series B Preferred Stock so converted, the Corporation shall (a) issue and deliver to such holder, or to his, her or its nominees, a certificate or certificates for the number of full shares of Common Stock issuable on such conversion in accordance with the provisions hereof and (b) pay cash as provided in Subsection 4.2 in lieu of any fraction of a share of Common Stock otherwise issuable upon such conversion and the payment of any declared but unpaid dividends on the shares of Series B Preferred Stock converted. Such converted Series B Preferred Stock shall be retired and cancelled and may not be reissued as shares of such series, and the Corporation may thereafter take such appropriate action (without the need for stockholder action) as may be necessary to reduce the authorized number of shares of Series B Preferred Stock accordingly.

5A.3. Definitions. For purposes of this Section 5A, the following definitions shall apply:

5A.3.1 “Affiliate” shall mean, with respect to any holder of shares of Series B Preferred Stock, any person, entity or firm which, directly or indirectly, controls, is controlled by or is under common control with such holder, including, without limitation, any entity of which the holder is a partner or member, any partner, officer, director, member or employee of such holder and any venture capital fund now or hereafter existing of which the holder is a partner or member which is controlled by or under common control with one or more general partners of such holder or shares the same management company with such holder.

5A.3.2 “Designated Amount” shall mean, with respect to any holder of Series B Preferred Stock, the number of shares of Series B Preferred Stock set forth opposite such holder’s name on Exhibit A to the Purchase Agreement under the heading “Second Tranche Shares” or “Third Tranche Shares,” as applicable.

5A.3.3 “Milestone Closing” shall mean the closing of the sale of Series B Preferred Stock in accordance with Sections 1.3(b) or 1.3(c) of the Purchase Agreement.

5A.3.4 “Purchase Agreement” means the Series B Preferred Stock Purchase Agreement dated on or about the Original Issue Date, by and among the Corporation and the other parties thereto, as the same may be amended from time to time.

6. Redemption. The Preferred Stock is not redeemable at the option of the holder thereof, except in accordance with Subsection 2.3.2(b).

7. Redeemed or Otherwise Acquired Shares. Any shares of Preferred Stock that are redeemed or otherwise acquired by the Corporation or any of its subsidiaries shall be automatically and immediately cancelled and retired and shall not be reissued, sold or transferred. Neither the Corporation nor any of its subsidiaries may exercise any voting or other rights granted to the holders of Preferred Stock following redemption.

8. Waiver. Any of the rights, powers, preferences and other terms of the Preferred Stock set forth herein may be waived on behalf of all holders of Preferred Stock by the affirmative written consent or vote of the holders of a majority of the shares of Preferred Stock then outstanding.

9. Notices. Any notice required or permitted by the provisions of this Article Fourth to be given to a holder of shares of Preferred Stock shall be mailed, postage prepaid, to the post office address last shown on the records of the Corporation, or given by electronic communication in compliance with the provisions of the General Corporation Law, and shall be deemed sent upon such mailing or electronic transmission.

FIFTH: Subject to any additional vote required by the Certificate of Incorporation or Bylaws, in furtherance and not in limitation of the powers conferred by statute, the Board is expressly authorized to make, repeal, alter, amend and rescind any or all of the Bylaws of the Corporation.

The books of the Corporation may be kept outside the State of Delaware at such place or places as may be designated from time to time by the Board or in the Bylaws of the Corporation.

NINTH: To the fullest extent permitted by law, a director of the Corporation shall not be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director. If the General Corporation Law or any other law of the State of Delaware is amended after approval by the stockholders of this Article Ninth to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the Corporation shall be eliminated or limited to the fullest extent permitted by the General Corporation Law as so amended.

Any repeal or modification of the foregoing provisions of this Article Ninth by the stockholders of the Corporation shall not adversely affect any right or protection of a director of the Corporation existing at the time of, or increase the liability of any director of the Corporation with respect to any acts or omissions of such director occurring prior to, such repeal or modification.

TENTH: To the fullest extent permitted by applicable law, the Corporation is authorized to provide indemnification of (and advancement of expenses to) directors, officers and agents of the Corporation (and any other persons to which General Corporation Law permits the Corporation to provide indemnification) through Bylaw provisions, agreements with such agents or other persons, vote of stockholders or disinterested directors or otherwise, in excess of the indemnification and advancement otherwise permitted by Section 145 of the General Corporation Law.

Any amendment, repeal or modification of the foregoing provisions of this Article Tenth shall not adversely affect any right or protection of any director, officer or other agent of the Corporation existing at the time of such amendment, repeal or modification.

ELEVENTH: The Corporation renounces, to the fullest extent permitted by law, any interest or expectancy of the Corporation in, or in being offered an opportunity to participate in, any Excluded Opportunity.

TWELFTH: For purposes of Section 500 of the California Corporations Code (to the extent applicable), in connection with any repurchase of shares of Common Stock permitted under this Amended and Restated Certificate of Incorporation from employees, officers, directors or consultants of the Corporation in connection with a termination of employment or services pursuant to agreements or arrangements approved by the Board of Directors (in addition to any other consent required under this Amended and Restated Certificate of Incorporation), such repurchase may be made without regard to any “preferential dividends arrears amount” or “preferential rights amount” (as those terms are defined in Section 500 of the California Corporations Code). Accordingly, for purposes of making any calculation under California Corporations Code Section 500 in connection with such repurchase, the amount of any “preferential dividends arrears amount” or “preferential rights amount” (as those terms are defined therein) shall be deemed to be zero (0).

Section 3. STOCKHOLDERS

3.1 Location of Meetings. All meetings of the stockholders shall be held at such place either within or without the State of Delaware as shall be designated from time to time by the board of directors, or if not so designated, at the registered office of the corporation.

If so authorized, and subject to such guidelines and procedures as the board of directors may adopt, stockholders and proxyholders not physically present at a meeting of stockholders may, by means of remote communication, participate in a meeting of stockholders whether such meeting is to be held at a designated place or solely by means of remote communication, provided that (i) the corporation shall implement reasonable measures to verify that each person deemed present and permitted to vote at the meeting by means of remote communication is a stockholder or proxyholder, (ii) the corporation shall implement reasonable measures to provide such stockholders and proxyholders a reasonable opportunity to participate in the meeting and to vote on matters submitted to the stockholders, including an opportunity to read or hear the proceedings of the meeting substantially concurrently with such proceedings, and (iii) if any stockholder or proxyholder votes or takes other action at the meeting by means of remote communication, a record of such vote or other action shall be maintained by the corporation. Any adjourned session of any meeting shall be held at the place designated in the vote of adjournment.

3.2 Annual Meeting. The annual meeting of stockholders shall be held at 10:00 a.m. on the second Wednesday in May in each year, unless that day be a legal holiday at the place where the meeting is to be held, in which case the meeting shall be held at the same hour on the next succeeding day not a legal holiday, or at such other date and time as shall be designated from time to time by the board of directors, at which they shall elect a board of directors and transact such other business as may be required by law or these by-laws or as may properly come before the meeting.

3.3 Special Meeting in Place of Annual Meeting. If the election for directors shall not be held on the day designated by these by-laws, the directors shall cause the election to be held as soon thereafter as convenient, and to that end, if the annual meeting is omitted on the day herein provided therefor or if the election of directors shall not be held thereat, a special meeting of the stockholders may be held in place of such omitted meeting or election, and any business transacted or election held at such special meeting shall have the same effect as if transacted or held at the annual meeting, and in such case all references in these by-laws to the annual meeting of the stockholders, or to the annual election of directors, shall be deemed to refer to or include such special meeting. Any such special meeting shall be called and the purposes thereof shall be specified in the call, as provided in Section 3.5.

3.4 Notice of Annual Meeting. Written notice of the annual meeting stating the place, date and hour of the meeting shall be given to each stockholder entitled to vote at such meeting not less than ten nor more than sixty days before the date of the meeting. Such notice may specify the business to be transacted and actions to be taken at such meeting. No action shall be taken at such meeting unless such notice is given or unless waiver of such notice is given in accordance with Section 5.2 by each stockholder entitled to such notice to whom such notice was not given.

3.5 Other Special Meetings. Special meetings of the stockholders, for any purpose or purposes, unless otherwise prescribed by law or by the certificate of incorporation, may be called by the president and shall be called by the president or secretary at the request in writing of a majority of the board of directors, or at the request in writing of the holders of at least ten percent of all capital stock of the corporation issued and outstanding and entitled to vote at such meeting. Such request shall state the purpose or purposes of the proposed meeting and business to be transacted at any special meeting of the stockholders.

3.6 Notice of Special Meeting. Written notice of a special meeting stating the place, date and hour of the meeting and the purpose or purposes for which the meeting is called, shall be given not less than ten nor more than sixty days before the date of the meeting, to each stockholder entitled to vote at such meeting. No action shall be taken at such meeting unless such notice is given or unless waiver of such notice is given in accordance with Section 5.2 by each stockholder entitled to such notice to whom such notice was not given.

3.7 Stockholder List. The officer who has charge of the stock ledger of the corporation shall prepare and make, at least ten days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting for a period of at least ten days prior to the meeting, either (i) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of the meeting, or (ii) during ordinary business hours, at the principal place of business of the corporation. In the event that the corporation determines to make the list available on an electronic network, the corporation may take reasonable steps to ensure that such information is available only to stockholders of the corporation. If the meeting is to be held at a place, then the list shall be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present. If the meeting is to be held solely by means of remote communication, then the list shall also be open to examination of any stockholder during the entire meeting on a reasonably accessible electronic network, and the information required to access such list shall be provided with the notice of the meeting.

3.8 Quorum of Stockholders. The holders of a majority of the stock issued and outstanding and entitled to vote thereat, present in person or represented by proxy, shall constitute a quorum at all meetings of the stockholders for the transaction of business except as otherwise required by law, by the certificate of incorporation or by these by-laws. Except as otherwise provided by law, no stockholder present at a meeting may withhold his shares from the quorum count by declaring his shares absent from the meeting.

3.9 Adjournment. Any meeting of stockholders may be adjourned from time to time to any other time and to any other place at which a meeting of stockholders may be held under these by-laws, which time and place shall be announced at the meeting, by a majority of votes cast upon the question, whether or not a quorum is present, or, if no stockholder is present or represented by proxy, by any officer entitled to preside at or to act as secretary of such meeting. At such adjourned meeting at which a quorum shall be present or represented any business may be transacted which might have been transacted at the original meeting. If the adjournment is for more than thirty days, or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting.

3.10 Proxy Representation. Every stockholder may authorize another person or persons to act for him by proxy in all matters in which a stockholder is entitled to participate, whether by waiving notice of any meeting, objecting to or voting or participating at a meeting, or expressing consent or dissent without a meeting. Every proxy must be signed by the stockholder or by his attorney-in-fact. No proxy shall be voted or acted upon after three years from its date unless such proxy provides for a longer period. Except as provided by law, a revocable proxy shall be deemed revoked if the stockholder is present at the meeting for which the proxy was given. A duly executed proxy shall be irrevocable if it states that it is irrevocable and, if, and only as long as, it is coupled with an interest sufficient in law to support an irrevocable power. A proxy may be made irrevocable regardless of whether the interest with which it is coupled is an interest in the stock itself or an interest in the corporation generally. The authorization of a proxy may, but need not be limited to specified action, provided, however, that if a proxy limits its authorization to a meeting or meetings of stockholders, unless otherwise specifically provided such proxy shall entitle the holder thereof to vote at any adjourned session but shall not be valid after the final adjournment thereof.

3.11 Inspectors. The directors or the person presiding at the meeting may, but need not unless required by law, appoint one or more inspectors of election and any substitute inspectors to act at the meeting or any adjournment thereof. Each inspector, before entering upon the discharge of his duties, shall take and sign an oath faithfully to execute the duties of inspector at such meeting with strict impartiality and according to the best of his ability. The inspectors, if any, shall determine the number of shares of stock outstanding and the voting power of each, the shares of stock represented at the meeting, the existence of a quorum and the validity and effect of proxies, and shall receive votes, ballots or consents, hear and determine all challenges and questions arising in connection with the right to vote, count and tabulate all votes, ballots or consents, determine the result, and do such acts as are proper to conduct the election or vote with fairness to all stockholders. On request of the person presiding at the meeting, the inspectors shall make a report in writing of any challenge, question or matter determined by them and execute a certificate of any fact found by them.

3.12 Action by Vote. When a quorum is present at any meeting, whether the same be an original or an adjourned session, a plurality of the votes properly cast for election to any office shall elect to such office and a majority of the votes properly cast upon any question other than an election to an office shall decide the question, except when a larger vote is required by law, by the certificate of incorporation or by these by-laws. No ballot shall be required for any election unless requested by a stockholder present or represented at the meeting and entitled to vote in the election.

3.13 Action Without Meetings. Unless otherwise provided in the certificate of incorporation, any action required to be taken at any annual or special meeting of stockholders of the corporation, or any action which may be taken at any annual or special meeting of such stockholders, may be taken without a meeting, without prior notice and without a vote, if a consent in writing, setting forth the action so taken shall be signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted. Prompt notice of the taking of the corporate action without a meeting by less than unanimous written consent shall be given to those stockholders who have not consented in writing. Consent may be given by electronic transmission to the extent permitted by the Delaware General Corporation Law.

3.14 Organization. Meetings of stockholders shall be presided over by the chairperson of the board of directors, if any, or in his absence by the president, or in his absence by a vice president, or in the absence of the foregoing persons by a chairperson chosen at the meeting by the board. The secretary shall act as secretary of the meeting, but in his absence the chairperson of the meeting may appoint any person to act as secretary of the meeting. The chairperson of the meeting shall announce at the meeting of stockholders the date and time of the opening and the closing of the polls for each matter upon which the stockholders will vote.

3.15 Conduct of Meetings. The board of directors of the corporation may adopt by resolution such rules and regulations for the conduct of the meeting of stockholders as it shall deem appropriate. Except to the extent inconsistent with such rules and regulations as adopted by the board of directors, the chairperson of any meeting of stockholders shall have the right and authority to prescribe such rules, regulations and procedures and to do all such acts as, in the judgment of such chairperson, are appropriate for the proper conduct of the meeting. Such rules, regulations or procedures, whether adopted by the board of directors or prescribed by the chairperson of the meeting, may include, without limitation, the following: (i) the establishment of an agenda or order of business for the meeting; (ii) rules and procedures for maintaining order at the meeting and the safety of those present; (iii) limitations on attendance at or participation in the meeting to stockholders of record of the corporation, their duly authorized and constituted proxies or such other persons as the chairperson of the meeting shall determine; (iv) restrictions on entry to the meeting after the time fixed for the commencement thereof; and (v) limitations on the time allotted to questions or comments by participants.

Thereafter, the stockholders at the annual meeting shall determine the number of directors, and the number of directors may be increased or decreased at any time or from time to time by the stockholders or by the directors by vote of a majority of directors then in office, except that any such decrease by vote of the directors shall only be made to eliminate vacancies existing by reason of the death, resignation or removal of one or more directors. The directors shall be elected at the annual meeting of the stockholders, except as provided in these by-laws. Directors need not be stockholders.

4.2 Tenure. Except as otherwise provided by law, by the certificate of incorporation or by these by-laws, each director shall hold office until the next annual meeting and until his successor is elected and qualified, or until he sooner dies, resigns, is removed or becomes disqualified.

4.3 Powers. The business of the corporation shall be managed by or under the direction of the board of directors which shall have and may exercise all the powers of the corporation and do all such lawful acts and things as are not by law, the certificate of incorporation or these by-laws directed or required to be exercised or done by the stockholders.

4.4 Vacancies. Vacancies and any newly created directorships resulting from any increase in the number of directors may be filled by vote of the stockholders at a meeting called for the purpose, or by a majority of the directors then in office, although less than a quorum, or by a sole remaining director. When one or more directors shall resign from the board, effective at a future date, a majority of the directors then in office, including those who have resigned, shall have power to fill such vacancy or vacancies, the vote or action in writing thereon to take effect when such resignation or resignations shall become effective. The directors shall have and may exercise all their powers notwithstanding the existence of one or more vacancies in their number, subject to any requirements of law or of the certificate of incorporation or of these by-laws as to the number of directors required for a quorum or for any vote or other actions.

4.5 Committees. The board of directors may, by vote of a majority of the whole board, (a) designate, change the membership of or terminate the existence of any committee or committees, each committee to consist of one or more of the directors; (b) designate one or more directors as alternate members of any such committee who may replace any absent or disqualified member at any meeting of the committee; and (c) determine the extent to which each such committee shall have and may exercise the powers and authority of the board of directors in the management of the business and affairs of the corporation, including the power to authorize the seal of the corporation to be affixed to all papers which require it and the power and authority to declare dividends onto authorize the issuance of stock; excepting, however, such powers which by law, by the certificate of incorporation or by these by-laws they are prohibited from so delegating. In the absence or disqualification of any member of such committee and his alternate, if any, the member or members thereof present at any meeting and not disqualified from voting, whether or not constituting a quorum, may unanimously appoint another member of the board of directors to act at the meeting in the place of any such absent or disqualified member. Except as the board of directors may otherwise determine, any committee may make, alter and repeal rules for the conduct of its business, but unless otherwise provided by the board or such rules, its business shall be conducted as nearly as may be in the same manner as is provided by these by-laws for the conduct of business by the board of directors. Each committee shall keep regular minutes of its meetings and report the same to the board of directors upon request.

4.6 Regular Meeting. Regular meetings of the board of directors may be held without call or notice at such place within or without the State of Delaware and at such times as the board may from time to time determine, provided that notice of the first regular meeting following any such determination shall be given to absent directors. A regular meeting of the directors may be held without call or notice immediately after and at the same place as the annual meeting of the stockholders.

4.7 Special Meetings. Special meetings of the board of directors may be held at any time and at any place within or without the State of Delaware designated in the notice of the meeting, when called by the president, or by any director, reasonable notice thereof being given to each director by the secretary or by the president or by any one of the directors calling the meeting.

Notice of a meeting need not be given to any director if a written waiver of notice, executed by him before or after the meeting, is filed with the records of the meeting, or to any director who attends the meeting without protesting prior thereto or at its commencement the lack of notice to him. Neither notice of a meeting nor a waiver of a notice need specify the purposes of the meeting.

Except as may be otherwise provided by law, by the certificate of incorporation or by these by-laws, at any meeting of the directors a majority of the directors then in office shall constitute a quorum. A quorum shall not in any case be less than a majority of the total number of directors constituting the whole board. Any meeting may be adjourned from time to time by a majority of the votes cast upon the question, whether or not a quorum is present, and the meeting may be held as adjourned without further notice.

4.10 Action by Vote. Except as may be otherwise provided by law, by the certificate of incorporation or by these by-laws, when a quorum is present at any meeting the vote of a majority of the directors present shall be the act of the board of directors.

4.11 Action Without a Meeting. Unless otherwise restricted by the certificate of incorporation or these by-laws, any action required or permitted to be taken at any meeting of the board of directors or of any committee thereof may be taken without a meeting if all the members of the board or of such committee, as the case may be, consent thereto in writing, or by electronic transmission, and the writing or writings or electronic transmission or transmissions are filed with the minutes of proceedings of the board, or committee. Such filing shall be in paper form if the minutes are maintained in paper form and shall be in electronic form if the minutes are maintained in electronic form. Such consent shall be treated for all purposes as the act of the board or of such committee, as the case may be.

4.12 Participation in Meetings by Conference Telephone. Unless otherwise restricted by the certificate of incorporation or these by-laws, members of the board of directors or of any committee thereof may participate in a meeting of such board or committee by means of conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other. Such participation shall constitute presence in person at such meeting.

4.13 Compensation. Unless otherwise restricted by the certificate of incorporation or these by-laws, the board of directors shall have the authority to fix from time to time the compensation of directors. The directors may be paid their expenses, if any, of attendance at each meeting of the board of directors and the performance of their responsibilities as directors and may be paid a fixed sum for attendance at each meeting of the board of directors and/or a stated salary as director. No such payment shall preclude any director from serving the corporation or its parent or subsidiary corporations in any other capacity and receiving compensation therefor. The board of directors may also allow compensation for members of special or standing committees for service on such committees.

4.14 Interested Directors and Officers.

(a) No contract or transaction between the corporation and one or more of its directors or officers, or between the corporation and any other corporation, partnership, association, or other organization in which one or more of the corporation’s directors or officers are directors or officers, or have a financial interest, shall be void or voidable solely for this reason, or solely because the director or officer is present at or participates in the meeting of the board or committee thereof which authorizes the contract or transaction, or solely because his or their votes are counted for such purpose, if:

(1) The material facts as to his relationship or interest and as to the contract or transaction are disclosed or are known to the board of directors or the committee, and the board or committee in good faith authorizes the contract or transaction by the affirmative votes of a majority of the disinterested directors, even though the disinterested directors be less than a quorum; or

(2) The material facts as to his relationship or interest and as to the contract or transaction are disclosed or are known to the stockholders entitled to vote thereon, and the contract or transaction is specifically approved in good faith by vote of the stockholders; or

(3) The contract or transaction is fair as to the corporation as of the time it is authorized, approved or ratified by the board of directors, a committee thereof, or the stockholders.

(b) Common or interested directors may be counted in determining the presence of a quorum at a meeting of the board of directors or of a committee which authorizes the contract or transaction.

4.15 Resignation or Removal of Directors. Unless otherwise restricted by the certificate of incorporation or by law, any director or the entire board of directors may be removed, with or without cause, by the holders of a majority of the stock issued and outstanding and entitled to vote at an election of directors. Any director may resign at any time by delivering his resignation in writing to the president or the secretary or to a meeting of the board of directors. Such resignation shall be effective upon receipt unless specified to be effective at some other time and without in either case the necessity of its being accepted unless the resignation shall so state. No director resigning and no director removed shall have any right to receive compensation as such director for any period following his resignation or removal, except where a right to receive compensation shall be expressly provided in a duly authorized written agreement with the corporation, or any right to damages on account of such removal, whether his compensation be by the month or by the year or otherwise; unless in the case of a resignation, the directors, or in the case of removal, the body acting on the removal, shall in their or its discretion provide for compensation.

Section 5. NOTICES

5.1 Form of Notice. Whenever, under the provisions of law, of the certificate of incorporation or of these by-laws, notice is required to be given to any director or stockholder, such notice may be given by mail, addressed to such director or stockholder, at his address as it appears on the records of the corporation, with postage thereon prepaid, and such notice shall be deemed to be given at the time when the same shall be deposited in the United States mail. Unless written notice by mail is required by law, written notice may also be given by telegram, cable, telecopy, commercial delivery service, telex or similar means, addressed to such director or stockholder at his address as it appears on the records of the corporation, in which case such notice shall be deemed to be given when delivered into the control of the persons charged with effecting such transmission, the transmission charge to be paid by the corporation or the person sending such notice and not by the addressee. Notice may also be given to any stockholder and to any director by any form of electronic transmission, to the same extent that Section 232 of the Delaware General Corporation Law permits notice in such form to be given to stockholders, and will be deemed given at the time provided therein.

Whenever notice is required to be given under the provisions of law, the certificate of incorporation or these by-laws, a written waiver thereof, signed by the person entitled to notice, or a waiver by electronic transmission by the person entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to notice. Attendance of a person at a meeting shall constitute a waiver of notice of such meeting, except when the person attends a meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any meeting of the stockholders, directors or members of a committee of the directors need be specified in any written waiver of notice.

provided, however, that each transferee, assignee, or other recipient of any interest in the Common Shares shall, as a condition to the transfer, agree to be bound by all of the restrictions set forth in these Bylaws.

(c) As a condition to any transfer, the Corporation may, in its sole discretion, (i) require in connection with such transfer of Common Shares delivery to the Corporation of a written opinion of legal counsel, in form and substance satisfactory to it or its legal counsel in their respective discretion, that such transfer is exempt from applicable federal, state or other securities laws and regulations (a “Legal Opinion”), (ii) charge the transferor, transferee or both a transfer fee in such amount as may be reasonably determined by the Corporation’s management in order to recoup the Corporation’s internal and external costs of processing such transfer, due and payable to the Corporation prior to or upon effectiveness of such transfer, and/or (iii) require such transfer to be effected pursuant to a standard form of transfer agreement in such customary and reasonable form as may be determined by the Corporation’s management from time to time in its discretion.

8.2 Right of First Refusal.

(a) General. In addition to and without limiting the effect of Section 8.1, prior to the effective date of a registration statement under the Securities Act of 1933, as amended (the “Act”), covering any shares of the Corporation’s Common Shares and until such time as the Corporation shall have effected a public offering of its Common Shares registered under the Act, in the event that, at any time when a Common Stockholder is permitted to do so, such Common Stockholder desires to sell, assign or otherwise transfer any Common Shares held by such Common Stockholder, such Common Stockholder shall first offer such shares to the Corporation by giving written notice of the Common Stockholder’s desire so to sell, assign or transfer such Common Shares.

(b) Notice of Intended Transfer. The notice shall state the number of Common Shares offered, the name of the person or persons to whom it is proposed to sell, assign or transfer such shares and the price at which such shares are intended to be sold, assigned or transferred. Such notice shall constitute an offer to the Corporation for the Corporation to purchase the number of Common Shares set forth in the notice at a price per share equal to the price stated therein.

(c) Corporation to Accept or Decline Within 30 Days. The Corporation may accept the offer as to all, but not less than all, the Common Shares by notifying the Common Stockholder in writing within 30 days after receipt of such notice of its acceptance of the offer. If the offer is accepted, the Corporation shall have 60 days after such acceptance within which to purchase the offered shares at a price per share as aforesaid. If within the applicable time periods the Common Stockholder does not receive notice of the Corporation’s intention to purchase the offered shares, or if payment in full of the purchase price is not made by the Corporation, the offer shall be deemed to have been rejected and the Common Stockholder may transfer title to such Common Shares within 90 days from the date of the Common Stockholder’s written notice to the Corporation of the Common Stockholder’s intention to sell, but such transfer shall be made only to the proposed transferee and at the proposed price as stated in such notice.

(d) Remedies of Corporation. No sale, assignment, pledge or other transfer of any of the Common Shares shall be effective or given effect on the books of the Corporation unless all of the applicable provisions of this Section 8.2 have been duly complied with, and the Corporation may inscribe on the face of any certificate representing any of such shares a legend referring to the provisions of this Section 8.2. If any transfer of Common Shares is made or attempted in violation of the foregoing restrictions, or if Common Shares are not offered to the Corporation as required hereby, the Corporation shall have the right to purchase such Common Shares from the owner thereof or his transferee at any time before or after the transfer, as herein provided. In addition to any other legal or equitable remedies which it may have, the Corporation may enforce its rights by actions for specific performance (to the extent permitted by law) and may refuse to recognize any transferee as one of its stockholders for any purpose, including, without limitation, for purposes of dividend and voting rights, until all applicable provisions hereof have been complied with.

(e) Legends on Stock Certificates. Any certificate representing shares of Common Shares may have endorsed thereon one or more legends, substantially as follows:

“Any disposition of any interest in the securities represented by this certificate is subject to restrictions, and the securities represented by this certificate are subject to certain options, contained in a certain agreement between the record holder hereof and the Corporation, a copy of which will be mailed to any holder of this certificate without charge upon receipt by the Corporation of a written request therefor.”

“The shares of stock represented by this certificate have not been registered under the Securities Act of 1933 or under the securities laws of any state and may not be pledged, hypothecated, sold or otherwise transferred unless such shares have been registered under the Act or unless the Corporation has received an opinion of counsel satisfactory to the Corporation, in form and substance satisfactory to the Corporation, that such registration is not required.”

(f) Right of First Refusal to Lapse Upon Registration. The restrictions imposed by this Section 8.2 shall terminate in all respects upon the effective date of a registration statement under the Act covering any of the Corporation’s Common Shares.

8.3 Transfer on Books. Subject to any restrictions with respect to the transfer of shares of stock, shares of stock may be transferred on the books of the corporation by the surrender to the corporation or its transfer agent of the certificate therefor properly endorsed or accompanied by a written assignment and power of attorney properly executed, with necessary transfer stamps affixed, and with such proof of the authenticity of signature as the board of directors or the transfer agent of the corporation may reasonably require. Except as may be otherwise required by law, by the certificate of incorporation or by these by-laws, the corporation shall be entitled to treat the record holder of stock as shown on its books as the owner of such stock for all purposes, including the payment of dividends and the right to receive notice and to vote or to give any consent with respect thereto and to be held liable for such calls and assessments, if any, as may lawfully be made thereon, regardless of any transfer, pledge or other disposition of such stock until the shares have been properly transferred on the books of the corporation.

It shall be the duty of each stockholder to notify the corporation of his post office address.

Section 9. GENERAL PROVISIONS

9.1 Record Date. In order that the corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, or to express consent to corporate action in writing without a meeting, or entitled to receive payment of any dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the board of directors may fix, in advance, a record date, which shall not be more than sixty days nor less than ten days before the date of such meeting, nor more than sixty days prior to any other action to which such record date relates. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the board of directors may fix a new record date for the adjourned meeting. If no record date is fixed,

(a) The record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held;

Dividends may be paid in cash, in property, or in shares of the capital stock, subject to the provisions of the certificate of incorporation.

9.3 Payment of Dividends. Before payment of any dividend, there may be set aside out of any funds of the corporation available for dividends such sum or sums as the directors from time to time, in their absolute discretion, think proper as a reserve or reserves to meet contingencies, or for equalizing dividends, or for repairing or maintaining any property of the corporation, or for such other purpose as the directors shall think conducive to the interest of the corporation, and the directors may modify or abolish any such reserve in the manner in which it was created.

9.4 Checks. All checks or demands for money and notes of the corporation shall be signed by such officer or officers or such other person or persons as the board of directors may from time to time designate.

9.5 Fiscal Year. The fiscal year of the corporation shall begin on the first of January in each year and shall end on the last day of December next following, unless otherwise determined by the board of directors.

9.6 Seal. The board of directors may, by resolution, adopt a corporate seal. The corporate seal shall have inscribed thereon the name of the corporation, the year of its organization and the word “Delaware.” The seal may be used by causing it or a facsimile thereof to be impressed or affixed or reproduced or otherwise. The seal may be altered from time to time by the board of directors.

Section 10. INDEMNIFICATION

10.1 It being the intent of the corporation to provide maximum protection available under the law to its officers and directors, the corporation shall indemnify its officers and directors to the full extent the corporation is permitted or required to do so by the Delaware General Corporation Law. In furtherance of and not in limitation of the foregoing, the corporation shall advance expenses, including attorneys’ fees, incurred by an officer or director of the corporation in defending any civil, criminal, administrative or investigative action, suit or proceeding in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such advances if it shall ultimately be determined that he is not entitled to be indemnified by the corporation. The corporation shall have the power to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or who is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the corporation has the power to indemnify such person under the Delaware General Corporation Law. Notwithstanding the foregoing, the Corporation shall not be required to indemnify or advance expenses to any person in connection with any action, suit, proceeding, claim or counterclaim initiated by or on behalf of such person.

Section 11. AMENDMENTS

11.1 These by-laws may be altered, amended or repealed or new by-laws may be adopted by the stockholders or by the board of directors when such power is conferred upon the board of directors by the certificate of incorporation, at any regular meeting of the stockholders or of the board of directors or at any special meeting of the stockholders or of the board of directors. If the power to adopt, amend or repeal by-laws is conferred upon the board of directors by the certificate of incorporation, it shall not divest or limit the power of the stockholders to adopt, amend or repeal by-laws.

2. Registration Rights. The Company covenants and agrees as follows:

2.1 Demand Registration.

(a) Form S-1 Demand. If at any time after the earlier of (i) 4 years after the date of this Agreement or (ii) 6 months after the effective date of the registration statement for the IPO, the Company receives a request from Holders of a majority of the Registrable Securities then outstanding that the Company file a Form S-1 registration statement with respect to outstanding Registrable Securities of such Holders having an anticipated aggregate offering price, net of Selling Expenses, of at least $10.0 million, then the Company shall (x) within 10 days after the date such request is given, give notice thereof (the “Demand Notice”) to all Holders other than the Initiating Holders; and (y) as soon as practicable, and in any event within 60 days after the date such request is given by the Initiating Holders, file a Form S-1 registration statement under the Securities Act covering all Registrable Securities that the Initiating Holders requested to be registered and any additional Registrable Securities requested to be included in such registration by any other Holders, as specified by notice given by each such Holder to the Company within 20 days of the date the Demand Notice is given, and in each case, subject to the limitations of Subsections 2.1(c), 2.1(d) and 2.3.

(b) Form S-3 Demand. If at any time when it is eligible to use a Form S-3 registration statement, the Company receives a request from Holders of Registrable Securities that the Company file a Form S-3 registration statement with respect to the outstanding Registrable Securities of such Holders having an anticipated aggregate offering price, net of Selling Expenses, of at least $1 million, then the Company shall (i) within 10 days after the date such request is given, give a Demand Notice to all Holders other than the Initiating Holders; and (ii) as soon as practicable, and in any event within 45 days after the date such request is given by the Initiating Holders, file a Form S-3 registration statement under the Securities Act covering all Registrable Securities requested to be included in such registration by any other Holders, as specified by notice given by each such Holder to the Company within 20 days of the date the Demand Notice is given, and in each case, subject to the limitations of Subsections 2.1(c), 2.1(d) and 2.3.

(c) Notwithstanding the foregoing obligations, if the Company furnishes to Holders requesting a registration pursuant to this Subsection 2.1 a certificate signed by the Company’s chief executive officer stating that in the good faith judgment of the Board of Directors it would be materially detrimental to the Company and its stockholders for such registration statement to either become effective or remain effective for as long as such registration statement otherwise would be required to remain effective, because such action would (i) materially interfere with a significant acquisition, corporate reorganization, or other similar transaction involving the Company; (ii) require premature disclosure of material information that the Company has a bona fide business purpose for preserving as confidential; or (iii) render the Company unable to comply with requirements under the Securities Act or Exchange Act, then the Company shall have the right to defer taking action with respect to such filing, and any time periods with respect to filing or effectiveness thereof shall be tolled correspondingly, for a period of not more than 90 days after the request of the Initiating Holders is given; provided, however, that the Company may not invoke this right more than once in any 12 month period; and provided further that the Company shall not register any securities for its own account or that of any other stockholder during such 90 day period other than an Excluded Registration.

(d) The Company shall not be obligated to effect, or to take any action to effect, any registration pursuant to Subsection 2.1(a) (i) if, within 30 days after receipt of a request for registration by the Initiating Holders pursuant to Section 2.1(a), the Company delivers notice to such Initiating Holders of its intent to file a registration statement within 60 days of the date on which the Company received such request and the Company is actively employing in good faith commercially reasonable efforts to cause such registration statement to become effective during such 60 day time period; (ii) after the Company has effected two registrations pursuant to Subsection 2.1(a); or (iii) if the Initiating Holders propose to dispose of shares of Registrable Securities that may be immediately registered on Form S-3 pursuant to a request made pursuant to Subsection 2.1(b). The Company shall not be obligated to effect, or to take any action to effect, any registration pursuant to Subsection 2.1(b) (i) during the period that is 30 days before the Company’s good faith estimate of the date of filing of, and ending on a date that is 90 days after the effective date of, a Company-initiated registration, provided that the Company is actively employing in good faith commercially reasonable efforts to cause such registration statement to become effective; or (ii) if the Company has effected two registrations pursuant to Subsection 2.1(b) within the 12 month period immediately preceding the date of such request. A registration shall not be counted as “effected” for purposes of this Subsection 2.1(d) until such time as the applicable registration statement has been declared effective by the SEC, unless the Initiating Holders withdraw their request for such registration, elect not to pay the registration expenses therefor, and forfeit their right to one demand registration statement pursuant to Subsection 2.6, in which case such withdrawn registration statement shall be counted as “effected” for purposes of this Subsection 2.1(d).

2.2 Company Registration. If the Company proposes to register (including, for this purpose, a registration effected by the Company for stockholders other than the Holders) any of its Common Stock under the Securities Act in connection with the public offering of such securities solely for cash (other than in an Excluded Registration), the Company shall, at such time, promptly give each Holder notice of such registration. Upon the request of each Holder given within 20 days after such notice is given by the Company, the Company shall, subject to the provisions of Subsection 2.3, cause to be registered all of the Registrable Securities that each such Holder has requested to be included in such registration. The Company shall have the right to terminate or withdraw any registration initiated by it under this Subsection 2.2 before the effective date of such registration, whether or not any Holder has elected to include Registrable Securities in such registration. The expenses (other than Selling Expenses) of such withdrawn registration shall be borne by the Company in accordance with Subsection 2.6.

2.3 Underwriting Requirements.

(a) If, pursuant to Subsection 2.1, the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to Subsection 2.1, and the Company shall include such information in the Demand Notice. The underwriter(s) will be selected by the Company and shall be reasonably acceptable to a majority in interest of the Initiating Holders. In such event, the right of any Holder to include such Holder’s Registrable Securities in such registration shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall (together with the Company as provided in Subsection 2.4(e)) enter into an underwriting agreement in customary form with the underwriter(s) selected for such underwriting. Notwithstanding any other provision of this Subsection 2.3, if the managing underwriter(s) advise(s) the Initiating Holders in writing that marketing factors require a limitation on the number of shares to be underwritten, then the Initiating Holders shall so advise all Holders of Registrable Securities that otherwise would be underwritten pursuant hereto, and the number of Registrable Securities that may be included in the underwriting shall be allocated among such Holders of Registrable Securities, including the Initiating Holders, in proportion (as nearly as practicable) to the number of Registrable Securities owned by each Holder or in such other proportion as shall mutually be agreed to by all such selling Holders; provided, however, that the number of Registrable Securities held by the Holders to be included in such underwriting shall not be reduced unless all other securities are first entirely excluded from the underwriting. To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest 100 shares.

(b) In connection with any offering involving an underwriting of shares of the Company’s capital stock pursuant to Subsection 2.2, the Company shall not be required to include any of the Holders’ Registrable Securities in such underwriting unless the Holders accept the terms of the underwriting as agreed upon between the Company and its underwriters, and then only in such quantity as the underwriters in their sole discretion determine will not jeopardize the success of the offering by the Company. If the total number of securities, including Registrable Securities, requested by stockholders to be included in such offering exceeds the number of securities to be sold (other than by the Company) that the underwriters in their reasonable discretion determine is compatible with the success of the offering, then the Company shall be required to include in the offering only that number of such securities, including Registrable Securities, which the underwriters and the Company in their sole discretion determine will not jeopardize the success of the offering. If the underwriters determine that less than all of the Registrable Securities requested to be registered can be included in such offering, then the Registrable Securities that are included in such offering shall be allocated among the selling Holders in proportion (as nearly as practicable to) the number of Registrable Securities owned by each selling Holder or in such other proportions as shall mutually be agreed to by all such selling Holders. To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest 100 shares. Notwithstanding the foregoing, in no event shall (i) the number of Registrable Securities included in the offering be reduced unless all other securities (other than securities to be sold by the Company) are first entirely excluded from the offering or (ii) the number of Registrable Securities included in the offering be reduced below 25% of the total number of securities included in such offering, unless such offering is the IPO, in which case the selling Holders may be excluded further if the underwriters make the determination described above and no other stockholder’s securities are included in such offering. For purposes of the provision in this Subsection 2.3(b) concerning apportionment, for any selling Holder that is a partnership, limited liability company, or corporation, the partners, members, retired partners, retired members, stockholders, and Affiliates of such Holder, or the estates and Immediate Family Members of any such partners, retired partners, members, and retired members and any trusts for the benefit of any of the foregoing Persons, shall be deemed to be a single “selling Holder,” and any pro rata reduction with respect to such “selling Holder” shall be based upon the aggregate number of Registrable Securities owned by all Persons included in such “selling Holder,” as defined in this sentence.

(c) For purposes of Subsection 2.1, a registration shall not be counted as “effected” if, as a result of an exercise of the underwriter’s cutback provisions in Subsection 2.3(a), fewer than 50% of the total number of Registrable Securities that Holders have requested to be included in such registration statement are actually included.

2.4 Obligations of the Company. Whenever required under this Section 2 to effect the registration of any Registrable Securities, the Company shall, as expeditiously as reasonably possible:

(a) prepare and file with the SEC a registration statement with respect to such Registrable Securities and use its commercially reasonable efforts to cause such registration statement to become effective and, upon the request of the Holders of a majority of the Registrable Securities registered thereunder, keep such registration statement effective for a period of up to 120 days or, if earlier, until the distribution contemplated in the registration statement has been completed; provided, however, that (i) such one hundred twenty (120) day period shall be extended for a period of time equal to the period the Holder refrains, at the request of an underwriter of Common Stock (or other securities) of the Company, from selling any securities included in such registration, and (ii) in the case of any registration of Registrable Securities on Form S-3 that are intended to be offered on a continuous or delayed basis, subject to compliance with applicable SEC rules, such 120 day period shall be extended for up to 180 days, if necessary, to keep the registration statement effective until all such Registrable Securities are sold;

(b) prepare and file with the SEC such amendments and supplements to such registration statement, and the prospectus used in connection with such registration statement, as may be necessary to comply with the Securities Act in order to enable the disposition of all securities covered by such registration statement;

(c) furnish to the selling Holders such numbers of copies of a prospectus, including a preliminary prospectus, as required by the Securities Act, and such other documents as the Holders may reasonably request in order to facilitate their disposition of their Registrable Securities;

(d) use its commercially reasonable efforts to register and qualify the securities covered by such registration statement under such other securities or blue-sky laws of such jurisdictions as shall be reasonably requested by the selling Holders; provided that the Company shall not be required to qualify to do business or to file a general consent to service of process in any such states or jurisdictions, unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act;

(e) in the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the underwriter(s) of such offering;

(f) use its commercially reasonable efforts to cause all such Registrable Securities covered by such registration statement to be listed on a national securities exchange or trading system and each securities exchange and trading system (if any) on which similar securities issued by the Company are then listed;

(g) provide a transfer agent and registrar for all Registrable Securities registered pursuant to this Agreement and provide a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration;

(h) promptly make available for inspection by the selling Holders, any managing underwriter(s) participating in any disposition pursuant to such registration statement, and any attorney or accountant or other agent retained by any such underwriter or selected by the selling Holders, all financial and other records, pertinent corporate documents, and properties of the Company, and cause the Company’s officers, directors, employees, and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant, or agent, in each case, as necessary or advisable to verify the accuracy of the information in such registration statement and to conduct appropriate due diligence in connection therewith;

(i) notify each selling Holder, promptly after the Company receives notice thereof, of the time when such registration statement has been declared effective or a supplement to any prospectus forming a part of such registration statement has been filed; and

(j) after such registration statement becomes effective, notify each selling Holder of any request by the SEC that the Company amend or supplement such registration statement or prospectus.

In addition, the Company shall ensure that, at all times after any registration statement covering a public offering of securities of the Company under the Securities Act shall have become effective, its insider trading policy shall provide that the Company’s directors may implement a trading program under Rule 10b5-1 of the Exchange Act.

2.5 Furnish Information. It shall be a condition precedent to the obligations of the Company to take any action pursuant to this Section 2 with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to the Company such information regarding itself, the Registrable Securities held by it, and the intended method of disposition of such securities as is reasonably required to effect the registration of such Holder’s Registrable Securities.

2.6 Expenses of Registration. All expenses (other than Selling Expenses) incurred in connection with registrations, filings, or qualifications pursuant to Section 2, including all registration, filing, and qualification fees; printers’ and accounting fees; fees and disbursements of counsel for the Company; and the reasonable fees and disbursements, not to exceed $50,000, of one counsel for the selling Holders (“Selling Holder Counsel”), shall be borne and paid by the Company; provided, however, that the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to Subsection 2.1 if the registration request is subsequently withdrawn at the request of the Holders of a majority of the Registrable Securities to be registered (in which case all selling Holders shall bear such expenses pro rata based upon the number of Registrable Securities that were to be included in the withdrawn registration), unless the Holders of a majority of the Registrable Securities agree to forfeit their right to one registration pursuant to Subsections 2.1(a) or 2.1(b), as the case may be; provided further that if, at the time of such withdrawal, the Holders shall have learned of a material adverse change in the condition, business, or prospects of the Company from that known to the Holders at the time of their request and have withdrawn the request with reasonable promptness after learning of such information then the Holders shall not be required to pay any of such expenses and shall not forfeit their right to one registration pursuant to Subsections 2.1(a) or 2.1(b). All Selling Expenses relating to Registrable Securities registered pursuant to this Section 2 shall be borne and paid by the Holders pro rata on the basis of the number of Registrable Securities registered on their behalf.

2.7 Delay of Registration. No Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any registration pursuant to this Agreement as the result of any controversy that might arise with respect to the interpretation or implementation of this Section 2.

2.8 Indemnification. If any Registrable Securities are included in a registration statement under this Section 2:

(a) To the extent permitted by law, the Company will indemnify and hold harmless each selling Holder, and the partners, members, officers, directors, and stockholders of each such Holder; legal counsel and accountants for each such Holder; any underwriter (as defined in the Securities Act) for each such Holder; and each Person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the Exchange Act, against any Damages, and the Company will pay to each such Holder, underwriter, controlling Person, or other aforementioned Person any legal or other expenses reasonably incurred thereby in connection with investigating or defending any claim or proceeding from which Damages may result, as such expenses are incurred; provided, however, that the indemnity agreement contained in this Subsection 2.8(a) shall not apply to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of the Company, which consent shall not be unreasonably withheld, nor shall the Company be liable for any Damages to the extent that they arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of any such Holder, underwriter, controlling Person, or other aforementioned Person expressly for use in connection with such registration.

(b) To the extent permitted by law, each selling Holder, severally and not jointly, will indemnify and hold harmless the Company, and each of its directors, each of its officers who has signed the registration statement, each Person (if any), who controls the Company within the meaning of the Securities Act, legal counsel and accountants for the Company, any underwriter (as defined in the Securities Act), any other Holder selling securities in such registration statement, and any controlling Person of any such underwriter or other Holder, against any Damages, in each case only to the extent that such Damages arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of such selling Holder expressly for use in connection with such registration; and each such selling Holder will pay to the Company and each other aforementioned Person any legal or other expenses reasonably incurred thereby in connection with investigating or defending any claim or proceeding from which Damages may result, as such expenses are incurred; provided, however, that the indemnity agreement contained in this Subsection 2.8(b) shall not apply to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; and provided further that in no event shall the aggregate amounts payable by any Holder by way of indemnity or contribution under Subsections 2.8(b) and 2.8(d) exceed the proceeds from the offering received by such Holder (net of any Selling Expenses paid by such Holder), except in the case of fraud or willful misconduct by such Holder.

(c) Promptly after receipt by an indemnified party under this Subsection 2.8 of notice of the commencement of any action (including any governmental action) for which a party may be entitled to indemnification hereunder, such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Subsection 2.8, give the indemnifying party notice of the commencement thereof. The indemnifying party shall have the right to participate in such action and, to the extent the indemnifying party so desires, participate jointly with any other indemnifying party to which notice has been given, and to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party (together with all other indemnified parties that may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such action. The failure to give notice to the indemnifying party within a reasonable time of the commencement of any such action shall relieve such indemnifying party of any liability to the indemnified party under this Subsection 2.8, to the extent that such failure materially prejudices the indemnifying party’s ability to defend such action. The failure to give notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Subsection 2.8.

(d) To provide for just and equitable contribution to joint liability under the Securities Act in any case in which either: (i) any party otherwise entitled to indemnification hereunder makes a claim for indemnification pursuant to this Subsection 2.8 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case, notwithstanding the fact that this Subsection 2.8 provides for indemnification in such case, or (ii) contribution under the Securities Act may be required on the part of any party hereto for which indemnification is provided under this Subsection 2.8, then, and in each such case, such parties will contribute to the aggregate losses, claims, damages, liabilities, or expenses to which they may be subject (after contribution from others) in such proportion as is appropriate to reflect the relative fault of each of the indemnifying party and the indemnified party in connection with the statements, omissions, or other actions that resulted in such loss, claim, damage, liability, or expense, as well as to reflect any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or allegedly untrue statement of a material fact, or the omission or alleged omission of a material fact, relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission; provided, however, that, in any such case (x) no Holder will be required to contribute any amount in excess of the public offering price of all such Registrable Securities offered and sold by such Holder pursuant to such registration statement, and (y) no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation; and provided further that in no event shall a Holder’s liability pursuant to this Subsection 2.8(d), when combined with the amounts paid or payable by such Holder pursuant to Subsection 2.8(b), exceed the proceeds from the offering received by such Holder (net of any Selling Expenses paid by such Holder), except in the case of willful misconduct or fraud by such Holder.

(e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control.

(f) Unless otherwise superseded by an underwriting agreement entered into in connection with the underwritten public offering, the obligations of the Company and Holders under this Subsection 2.8 shall survive the completion of any offering of Registrable Securities in a registration under this Section 2, and otherwise shall survive the termination of this Agreement.

2.9 Reports Under Exchange Act. With a view to making available to the Holders the benefits of SEC Rule 144 and any other rule or regulation of the SEC that may at any time permit a Holder to sell securities of the Company to the public without registration or pursuant to a registration on Form S-3, the Company shall:

(a) make and keep available adequate current public information, as those terms are understood and defined in SEC Rule 144, at all times after the effective date of the registration statement filed by the Company for the IPO;

(b) use commercially reasonable efforts to file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act (at any time after the Company has become subject to such reporting requirements); and

(c) furnish to any Holder, so long as the Holder owns any Registrable Securities, forthwith upon request (i) to the extent accurate, a written statement by the Company that it has complied with the reporting requirements of SEC Rule 144 (at any time after ninety (90) days after the effective date of the registration statement filed by the Company for the IPO), the Securities Act, and the Exchange Act (at any time after the Company has become subject to such reporting requirements), or that it qualifies as a registrant whose securities may be resold pursuant to Form S-3 (at any time after the Company so qualifies); and such other information as may be reasonably requested in availing any Holder of any rule or regulation of the SEC that permits the selling of any such securities without registration (at any time after the Company has become subject to the reporting requirements under the Exchange Act) or pursuant to Form S-3 (at any time after the Company so qualifies to use such form).

2.10 Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the Company shall not, without the prior written consent of the Holders of a majority of the Registrable Securities then outstanding, enter into any agreement with any holder or prospective holder of any securities of the Company that would allow such holder or prospective holder to include such securities in any registration if such agreement (a) would allow such holder or prospective holder to include a portion of its securities in any “piggyback” registration if such inclusion would reduce the number of Registrable Securities that selling Holders could be entitled to include in such registration under Subsections 2.2 and 2.3(b) hereof or (b) would allow such holder or prospective holder to initiate a demand for registration of any of its securities at a time earlier than the Holders of Registrable Securities can demand registration under Subsection 2.1 hereof; provided that this limitation shall not apply to any additional Investor who becomes a party to this Agreement in accordance with Subsection 6.10.

2.11 “Market Stand-off” Agreement. Each Holder hereby agrees that it will not, without the prior written consent of the managing underwriter, during the period commencing on the date of the final prospectus relating to the registration by the Company of shares of its Common Stock or any other equity securities under the Securities Act on a registration statement on Form S-1 or Form S-3 and ending on the date specified by the Company and the managing underwriter (such period not to exceed 180 days), (i) lend; offer; pledge; sell; contract to sell; sell any option or contract to purchase; purchase any option or contract to sell; grant any option, right, or warrant to purchase; or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable (directly or indirectly) for Common Stock (whether such shares or any such securities are then owned by the Holder or are thereafter acquired) or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of such securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or other securities, in cash, or otherwise. The foregoing provisions of this Subsection 2.11 shall apply only to the IPO, shall not apply to the sale of any shares to an underwriter pursuant to an underwriting agreement, or the transfer of any shares to any trust for the direct or indirect benefit of the Holder or the immediate family of the Holder, provided that the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, and shall be applicable to the Holders only if all officers and directors are subject to the same restrictions and the Company uses commercially reasonable efforts to obtain a similar agreement from all stockholders individually owning more than 1% of the Company’s outstanding Common Stock (after giving effect to conversion into Common Stock of all outstanding Preferred Stock). The underwriters in connection with such registration are intended third-party beneficiaries of this Subsection 2.11 and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. Each Holder further agrees to execute such agreements as may be reasonably requested by the underwriters in connection with such registration that are consistent with this Subsection 2.11 or that are necessary to give further effect thereto. Any discretionary waiver or termination of any “market stand-off” restrictions or any restrictions similar to those set forth in this Subsection 2.11 shall apply pro rata to all Holders.

2.12 Restrictions on Transfer.

(a) The Preferred Stock and the Registrable Securities shall not be sold, pledged, or otherwise transferred, and the Company shall not recognize and shall issue stop-transfer instructions to its transfer agent with respect to any such sale, pledge, or transfer, except upon the conditions specified in this Agreement, which conditions are intended to ensure compliance with the provisions of the Securities Act. A transferring Holder will cause any proposed purchaser, pledgee, or transferee of the Preferred Stock and the Registrable Securities held by such Holder to agree to take and hold such securities subject to the provisions and upon the conditions specified in this Agreement.

(b) Each certificate, instrument, or book entry representing (i) the Preferred Stock, (ii) the Registrable Securities, and (iii) any other securities issued in respect of the securities referenced in clauses (i) and (ii), upon any stock split, stock dividend, recapitalization, merger, consolidation, or similar event, shall (unless otherwise permitted by the provisions of Subsection 2.12(c)) be notated with a legend substantially in the following form:

THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR ANY STATE SECURITIES LAWS, AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH TRANSFER MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL IN A FORM SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE ACT OR UNDER APPLICABLE STATE SECURITIES LAWS.

THE SHARES REPRESENTED HEREBY MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY.

The Holders consent to the Company making a notation in its records and giving instructions to any transfer agent of the Restricted Securities in order to implement the restrictions on transfer set forth in this Subsection 2.12.

(c) The holder of such Restricted Securities, by acceptance of ownership thereof, agrees to comply in all respects with the provisions of this Section 2. Before any proposed sale, pledge, or transfer of any Restricted Securities, unless there is in effect a registration statement under the Securities Act covering the proposed transaction, the Holder thereof shall give notice to the Company of such Holder’s intention to effect such sale, pledge, or transfer. Each such notice shall describe the manner and circumstances of the proposed sale, pledge, or transfer in sufficient detail and, if reasonably requested by the Company, shall be accompanied at such Holder’s expense by either (i) a written opinion of legal counsel who shall, and whose legal opinion shall, be reasonably satisfactory to the Company, addressed to the Company, to the effect that the proposed transaction may be effected without registration under the Securities Act; (ii) a “no action” letter from the SEC to the effect that the proposed sale, pledge, or transfer of such Restricted Securities without registration will not result in a recommendation by the staff of the SEC that action be taken with respect thereto; or (iii) any other evidence reasonably satisfactory to counsel to the Company to the effect that the proposed sale, pledge, or transfer of the Restricted Securities may be effected without registration under the Securities Act, whereupon the Holder of such Restricted Securities shall be entitled to sell, pledge, or transfer such Restricted Securities in accordance with the terms of the notice given by the Holder to the Company. The Company will not require such a legal opinion or “no action” letter (x) in any transaction in compliance with SEC Rule 144; or (y) in any transaction in which such Holder distributes Restricted Securities to an Affiliate of such Holder for no consideration; provided that each transferee agrees in writing to be subject to the terms of this Subsection 2.12. Each certificate, instrument, or book entry representing the Restricted Securities transferred as above provided shall be notated with, except if such transfer is made pursuant to SEC Rule 144, the appropriate restrictive legend set forth in Subsection 2.12(b), except that such certificate instrument, or book entry shall not be notated with such restrictive legend if, in the opinion of counsel for such Holder and the Company, such legend is not required in order to establish compliance with any provisions of the Securities Act.

2.13 Termination of Registration Rights. The right of any Holder to request registration or inclusion of Registrable Securities in any registration pursuant to Subsections 2.1 or 2.2 shall terminate upon the earliest to occur of:

(a) at such time following the IPO as a Holder holds less than 1% of the outstanding capital stock of the Company and Rule 144 or another similar exemption under the Securities Act is available for the sale of all of such Holder’s shares without limitation during a three-month period without registration; and

(b) the fifth anniversary of the QPO.

3. Information and Observer Rights.

3.1 Delivery of Financial Statements. The Company shall deliver to each Major Investor, provided that the Board of Directors has not reasonably determined that such Major Investor is a competitor of the Company; provided, further, that any Major Investor that is a financial investment firm shall not be deemed a competitor of the Company solely due to such Major Investor’s investment in one or more competitors of the Company; provided, further, that none of Bayer HealthCare LLC and its Affiliates, New Enterprise Associates 15, Limited Partnership and its Affiliates (together, “NEA”), 8VC Fund I, L.P. and its Affiliates (together, “8VC”), Pear Ventures II, L.P. and its Affiliates (“Pear”) or Lux Ventures IV, L.P. and its Affiliates (together, “Lux”) shall be deemed a competitor of the Company for purposes of this Agreement:

(d) as soon as practicable, but in any event within 30 days of the end of each month, an unaudited income statement and statement of cash flows for such month, and a comparison between (x) the actual amounts as of and for such month and (y) the comparable amounts for the prior month and as included in the Budget (as defined in Subsection 3.1(e)) for such month, with an explanation of any material differences between such amounts and a schedule as to the sources and applications of funds for such month, and an unaudited balance sheet and statement of stockholders’ equity as of the end of such month, all prepared in accordance with GAAP (except that such financial statements may (i) be subject to normal year-end audit adjustments and (ii) not contain all notes thereto that may be required in accordance with GAAP); and

(e) as soon as practicable, but in any event 30 days before the end of each fiscal year, a budget and business plan for the next fiscal year (collectively, the “Budget”), prepared on a monthly basis, including balance sheets, income statements, and statements of cash flow for such months and, promptly after prepared, any other budgets or revised budgets prepared by the Company.

If, for any period, the Company has any subsidiary whose accounts are consolidated with those of the Company, then in respect of such period the financial statements delivered pursuant to the foregoing sections shall be the consolidated and consolidating financial statements of the Company and all such consolidated subsidiaries.

Notwithstanding anything else in this Subsection 3.1 to the contrary, the Company may cease providing the information set forth in this Subsection 3.1 during the period starting with the date 60 days before the Company’s good-faith estimate of the date of filing of a registration statement if it reasonably concludes it must do so to comply with the SEC rules applicable to such registration statement and related offering; provided that the Company’s covenants under this Subsection 3.1 shall be reinstated at such time as the Company is no longer actively employing its commercially reasonable efforts to cause such registration statement to become effective.

3.2 Inspection. The Company shall permit each Major Investor (provided that the Board of Directors has not reasonably determined that such Major Investor is a competitor of the Company; provided, further, that any Major Investor that is a financial investment firm shall not be deemed a competitor of the Company solely due to such Major Investor’s investment in one or more competitors of the Company; provided, further, that none of NEA, 8VC, Pear or Lux shall be deemed a competitor of the Company for purposes of this Agreement), at such Major Investor’s expense, to visit and inspect the Company’s properties; examine its books of account and records; and discuss the Company’s affairs, finances, and accounts with its officers, during normal business hours of the Company as may be reasonably requested by the Major Investor; provided, however, that the Company shall not be obligated pursuant to this Subsection 3.2 to provide access to any information that it reasonably and in good faith considers to be a trade secret or confidential information (unless covered by an enforceable confidentiality agreement, in form acceptable to the Company) or the disclosure of which would adversely affect the attorney-client privilege between the Company and its counsel.

3.3 Observer Rights. As long as (a) Bayer HealthCare LLC and its Affiliates (together, “Bayer”) owns at least 1,826,261 shares of Preferred Stock or (b) NEA owns at least 2,005,289 shares of Preferred Stock (or, in each case, an equivalent amount of Common Stock issued upon conversion thereof, but excluding shares of Common Stock issued upon conversion of the Preferred Stock pursuant to the “Special Mandatory Conversion” provisions of the Restated Certificate), the Company shall invite a representative of Bayer and NEA, respectively, to attend all meetings of its Board of Directors in a nonvoting observer capacity and, in this respect, shall give such representative copies of all notices, minutes, consents, and other materials that it provides to its directors at substantially the same time and in substantially the same manner as provided to such directors; provided, however, that such representative shall not be an employee of a competitor of the Company; provided, further, that such representative shall agree to hold in confidence and trust with respect to all information so provided; and provided further, that the Company reserves the right to withhold any information and to exclude such representative from any meeting or portion thereof if, upon advice of the Company’s counsel, access to such information or attendance at such meeting would (i) adversely affect the attorney-client privilege between the Company and its counsel, (ii) result in disclosure of trade secrets or (iii) result in an actual conflict of interest.

3.4 Termination of Information Rights. The covenants set forth in Subsection 3.1, Subsection 3.2 and Subsection 3.3 shall terminate and be of no further force or effect (i) immediately before the consummation of the IPO, (ii) when the Company first becomes subject to the periodic reporting requirements of Section 12(g) or 15(g) of the Exchange Act, or (iii) upon a Deemed Liquidation Event, in which the consideration is cash and/or freely-tradeable and marketable securities, whichever event occurs first.

3.5 Confidentiality. Each Investor agrees that such Investor will keep confidential and will not disclose, divulge, or use for any purpose (other than to monitor its investment in the Company) any confidential information obtained from the Company pursuant to the terms of this Agreement (including notice of the Company’s intention to file a registration statement and, for the avoidance of doubt, any information obtained pursuant to Sections 3.1 through 3.3 of this Agreement), unless such confidential information (a) is known or becomes known to the public in general (other than as a result of a breach of this Subsection 3.5 by such Investor), (b) is or has been independently developed or conceived by the Investor without use of the Company’s confidential information, or (c) is or has been made known or disclosed to the Investor by a third party without a breach of any obligation of confidentiality such third party may have to the Company; provided, however, that an Investor may disclose confidential information (i) to its attorneys, accountants, consultants, and other professionals to the extent necessary to obtain their services in connection with monitoring its investment in the Company; (ii) to any prospective purchaser of any Registrable Securities from such Investor, if such prospective purchaser agrees to be bound by the provisions of this Subsection 3.5; (iii) to any Affiliate, partner, member, stockholder, or wholly owned subsidiary of such Investor in the ordinary course of business, provided that such Investor informs such Person that such information is confidential and directs such Person to maintain the confidentiality of such information, and provided, further, that notwithstanding anything to the contrary in this Agreement, Bayer HealthCare LLC may not disclose any confidential information to BlueRock Therapeutics, LP; or (iv) as may otherwise be required by law, provided that the Investor promptly notifies the Company of such disclosure and takes reasonable steps to minimize the extent of any such required disclosure.

4. Rights to Future Stock Issuances.

4.1 Right of First Offer. Subject to the terms and conditions of this Subsection 4.1 and applicable securities laws, if the Company proposes to offer or sell any New Securities, the Company shall first offer such New Securities to each Major Investor. A Major Investor shall be entitled to apportion the right of first offer hereby granted to it, in such proportions as it deems appropriate, among (i) itself and (ii) its Affiliates.

(a) The Company shall give notice (the “Offer Notice”) to each Major Investor, stating (i) its bona fide intention to offer such New Securities, (ii) the number of such New Securities to be offered, and (iii) the price and terms, if any, upon which it proposes to offer such New Securities.

(b) By notification to the Company within 20 days after the Offer Notice is given, each Major Investor may elect to purchase or otherwise acquire, at the price and on the terms specified in the Offer Notice, up to that portion of such New Securities which equals the proportion that the Common Stock then held by such Major Investor (including all shares of Common Stock then issuable (directly or indirectly) upon conversion and/or exercise, as applicable, of the Preferred Stock and any other Derivative Securities then held by such Major Investor) bears to the total Common Stock of the Company then outstanding (assuming full conversion and/or exercise, as applicable, of all Preferred Stock and other Derivative Securities). At the expiration of such 20 day period, the Company shall promptly notify each Major Investor that elects to purchase or acquire all the shares available to it (each, a “Fully Exercising Investor”) of any other Major Investor’s failure to do likewise. During the 10 day period commencing after the Company has given such notice, each Fully Exercising Investor may, by giving notice to the Company, elect to purchase or acquire, in addition to the number of shares specified above, up to that portion of the New Securities for which Major Investors were entitled to subscribe but that were not subscribed for by the Major Investors which is equal to the proportion that the Common Stock issued and held, or issuable (directly or indirectly) upon conversion and/or exercise, as applicable, of Preferred Stock and any other Derivative Securities then held, by such Fully Exercising Investor bears to the Common Stock issued and held, or issuable (directly or indirectly) upon conversion and/or exercise, as applicable, of the Preferred Stock and any other Derivative Securities then held, by all Fully Exercising Investors who wish to purchase such unsubscribed shares. The closing of any sale pursuant to this Subsection 4.1(b) shall occur no later than the later of 120 days following the date that the Offer Notice is given and the date of initial sale of New Securities pursuant to Subsection 4.1(c).

(c) If all New Securities referred to in the Offer Notice are not elected to be purchased or acquired as provided in Subsection 4.1(b), the Company may, during the 90 day period following the expiration of the periods provided in Subsection 4.1(b), offer and sell the remaining unsubscribed portion of such New Securities to any Person or Persons at a price not less than, and upon terms no more favorable to the offeree than, those specified in the Offer Notice. If the Company does not enter into an agreement for the sale of the New Securities within such period, or if such agreement is not consummated within 30 days of the execution thereof, the right provided hereunder shall be deemed to be revived and such New Securities shall not be offered unless first reoffered to the Major Investors in accordance with this Subsection 4.1.

(d) The right of first offer in this Subsection 4.1 shall not be applicable to (i) Exempted Securities (as defined in the Restated Certificate); (ii) shares of Common Stock issued in the IPO in which all shares of Preferred Stock have converted into shares of Common Stock, and (iii) the issuance of shares of Series B Preferred Stock pursuant to the Purchase Agreement.

(e) The right of first offer set forth in this Subsection 4.1 (i) shall terminate with respect to any Major Investor immediately upon the conversion of the shares of Preferred Stock held by such Major Investor into shares of Common Stock pursuant to the “Special Mandatory Conversion” provisions of the Restated Certificate, and (ii) shall not be applicable to any Major Investor if (A) at the time of such offering of New Securities, such Major Investor is not an “accredited investor,” as such term is then defined in Rule 501(a) under the Securities Act, and (B) such New Securities are otherwise being offered only to accredited investors.

4.2 Termination. The covenants set forth in Subsection 4.1 shall terminate and be of no further force or effect (i) immediately before the consummation of the QPO, or (ii) upon a Deemed Liquidation Event, in which the consideration is cash and/or freely tradeable and marketable securities, whichever event occurs first and, with respect to each Major Investor, in accordance with Subsection 4.1(e)(i).

5. Additional Covenants.

5.1 Insurance. The Company shall use its commercially reasonable efforts to maintain its Directors and Officers liability insurance on terms and conditions reasonably satisfactory to the Board of Directors and in an amount equal to no less than $2,000,000 until such time as the Board of Directors determines that such insurance should be discontinued.

5.2 Employee Agreements. The Company will cause each person now or hereafter employed by it or by any subsidiary (or engaged by the Company or any subsidiary as a consultant/independent contractor) to enter into a nondisclosure and proprietary rights assignment agreement or an employment or consulting agreement providing that (i) such person is either an at-will employee or a consultant of the Company, as the case may be, (ii) such person will maintain all Company proprietary information in confidence, (iii) such person will assign all inventions created by him as an employee or consultant during his employment or service to the Company, and (iv) such person will not disclose any information related to the Company’s work force and will not solicit any employees from the Company for a period of 12 months should his employment or service to the Company be terminated for any reason.

5.3 Employee Stock and Options. Unless otherwise approved by the Board of Directors, including at least one Series A Director and at least one Series B Director, all future employees and consultants of the Company who purchase, receive options to purchase, or receive awards of shares of the Company’s capital stock after the date hereof shall be required to execute restricted stock or option agreements, as applicable, providing for (i) vesting of shares over a four year period, with the first 25% of such shares vesting following 12 months of continued employment or service, and the remaining shares vesting in equal monthly installments over the following 36 months, and (ii) a market stand-off provision substantially similar to that in Subsection 2.11. All option grants after the date hereof shall require the approval of the Board of Directors, including at least one Series A Director and at least one Series B Director. In addition, unless otherwise approved by the Board of Directors, the Company shall retain a “right of first refusal” on employee transfers until the Company’s IPO and shall have the right to repurchase unvested shares at cost upon termination of employment of a holder of restricted stock.

5.4 Matters Requiring Preferred Director Approval. During such time or times as the holders of Preferred Stock are entitled to elect a Preferred Director and such seat is filled, the Company hereby covenants and agrees with each of the Investors that it shall not, without approval of the Board of Directors, which approval must include the affirmative vote of a majority of the Preferred Directors then serving:

(a) Make, or permit any subsidiary to make, any loan or advance to, or own any stock or other securities of, any subsidiary or other corporation, partnership, or other entity unless it is wholly owned by the Company;

(b) Make, or permit any subsidiary to make, any loan or advance to any Person, including, without limitation, any employee or director of the Company or any subsidiary, except advances and similar expenditures in the ordinary course of business;

(c) Guarantee, directly or indirectly, or permit any subsidiary to guarantee, directly or indirectly, any indebtedness except for trade accounts of the Company or any subsidiary arising in the ordinary course of business;

(d) Make any investment other than investments in prime commercial paper, money market funds, certificates of deposit in any U.S. bank having a credit rating of at least A-2/A- by Moody’s Investors’ Service and Standard & Poor’s or obligations issued or guaranteed by the U.S. government, in each case having a maturity not in excess of two years, unless such investment is made in accordance with the Company’s Investment Policy that has been approved by a majority of the Preferred Directors; or

(e) Hire, terminate, or change the cash or equity compensation of the executive officers, including approving any option grants or stock awards to executive officers.

5.5 Board Matters. Unless otherwise determined by the vote of a majority of the directors then in office, the Board of Directors shall meet at least quarterly in accordance with an agreed-upon schedule. The Company shall reimburse the non-employee directors and observers for all reasonable out-of-pocket travel expenses incurred (consistent with the Company’s travel policy) in connection with attending meetings of the Board of Directors or any committee thereof and any other meetings or other activities attended on behalf of the Company at the Company’s request. Upon approval of the Board of Directors, the Company shall cause to be established and will maintain, a compensation committee, for the purpose, among other things, of reviewing and determining the compensation of the Company’s executive officers, which shall consist solely of non-management directors, including at least one Series A Director and at least one Series B Director. Each non-employee director shall be entitled in such person’s discretion to be a member of any committee of the Board of Directors.

5.6 Successor Indemnification. If the Company or any of its successors or assignees consolidates with or merges into any other Person and is not the continuing or surviving corporation or entity of such consolidation or merger, then to the extent necessary, proper provision shall be made so that the successors and assignees of the Company assume the obligations of the Company with respect to indemnification of members of the Board of Directors as in effect immediately before such transaction, whether such obligations are contained in the Company’s Bylaws, the Restated Certificate, or elsewhere, as the case may be.

5.7 Right to Conduct Activities. The Company hereby agrees and acknowledges that certain of the Investors, including NEA, for the avoidance of doubt, are professional investment funds, and as such invest in numerous portfolio companies, some of which may be deemed competitive with the Company’s business (as currently conducted or as currently proposed to be conducted). The Company hereby agrees that, to the extent permitted under applicable law, any such Investors shall not be liable to the Company for any claim arising out of, or based upon, (i) the investment by such Investor in any entity competitive with the Company, or (ii) actions taken by any partner, officer or other representative of such Investor to assist any such competitive company, whether or not such action was taken as a member of the board of directors of such competitive company or otherwise, and whether or not such action has a detrimental effect on the Company; provided, however, that the foregoing shall not relieve (x) any of the Investors from liability associated with the unauthorized disclosure of the Company’s confidential information obtained pursuant to this Agreement or otherwise, or (y) any director or officer of the Company from any liability associated with his or her fiduciary duties to the Company.

5.8 Indemnification Matters. The Company hereby acknowledges that each of the Preferred Directors may have certain rights to indemnification, advancement of expenses and/or insurance provided by one or more of the Investors and/or certain of its Affiliates (collectively, the “Fund Indemnitors”). The Company hereby agrees (i) that it is the indemnitor of first resort (i.e., its obligations to a Preferred Director are primary and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by a Preferred Director are secondary), (ii) that it shall be required to advance the full amount of expenses incurred by a Preferred Director and shall be liable for the full amount of all expenses, judgments, penalties, fines and amounts paid in settlement by or on behalf of any such Preferred Director to the extent legally permitted and as required by the Restated Certificate or Bylaws (or any agreement between the Company and a Preferred Director), without regard to any rights a Preferred Director may have against the Fund Indemnitors, and, (iii) that it irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all claims against the Fund Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Fund Indemnitors on behalf of a Preferred Director with respect to any claim for which a Preferred Director has sought indemnification from the Company shall affect the foregoing and the Fund Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of a Preferred Director against the Company.

5.9 Qualified Small Business Stock. The Company shall use commercially reasonable efforts to cause the shares of Series A Preferred Stock and Series B Preferred Stock in the Initial Closing (as defined in the Purchase Agreement), as well as any shares into which such shares are converted, within the meaning of Section 1202(f) of the Code, to constitute “qualified small business stock” as defined in Section 1202(c) of the Code; provided, however, that such requirement shall not be applicable if the Board of Directors of the Company determines, in its good-faith business judgment, that such qualification is inconsistent with the best interests of the Company. The Company shall submit to its stockholders (including the Investors) and to the Internal Revenue Service any reports that may be required under Section 1202(d)(1)(C) of the Internal Revenue Code (the “Code”) and the regulations promulgated thereunder. In addition, within 20 business days of the Company’s receipt of any Investor’s written request therefor, the Company shall, at its option, either (i) deliver to such Investor a written statement indicating whether (and what portion of) such Investor’s interest in the Company constitutes “qualified small business stock” as defined in Section 1202(c) of the Code or (ii) deliver to such Investor such factual information in the Company’s possession as is reasonably necessary to enable such Investor to determine whether (and what portion of) such Investor’s interest in the Company constitutes “qualified small business stock” as defined in Section 1202(c) of the Code. For the avoidance of doubt, the Company in no event shall be liable to the Investors or any other party for any damages arising from any subsequently proven or identified error in any report or information provided to the Investors or such other party pursuant to this Subsection 5.9, unless such error is due to the gross negligence or fraud on the part of the Company.

5.10 FIRPTA Compliance. The Company shall provide prompt notice to each Investor following any “determination date” (as defined in Treasury Regulation Section 1.897-2(c)(1)) on which the Company becomes a United States real property holding corporation. In addition, within 20 business days of the Company’s receipt of any Investor’s written request therefor, the Company shall provide such Investor with a written statement informing such Investor whether such Investor’s interest in the Company constitutes a United States real property interest. The Company’s determination shall comply with the requirements of Treasury Regulation Section 1.897-2(h)(1) or any successor regulation, and the Company shall provide timely notice to the Internal Revenue Service, in accordance with and to the extent required by Treasury Regulation Section 1.897-2(h)(2) or any successor regulation, that such statement has been made. The Company’s obligation to furnish such written statement shall continue notwithstanding the fact that a class of the Company’s stock may be traded on an established securities market or the fact that there is no preferred stock then outstanding. Termination of Covenants. The covenants set forth in this Section 5, except for Subsection 5.6, shall terminate and be of no further force or effect (i) immediately before the consummation of the QPO, or (ii) upon a Deemed Liquidation Event, whichever event occurs first.

6. Miscellaneous.

6.1 Successors and Assigns. The rights under this Agreement may be assigned (but only with all related obligations) by a Holder to a transferee of Registrable Securities that (i) is an Affiliate of a Holder; (ii) is a Holder’s Immediate Family Member or trust for the benefit of an individual Holder or one or more of such Holder’s Immediate Family Members; or (iii) after such transfer, holds at least 2% of the Registrable Securities; provided, however, that (x) the Company is, within a reasonable time after such transfer, furnished with written notice of the name and address of such transferee and the Registrable Securities with respect to which such rights are being transferred; and (y) such transferee agrees in a written instrument delivered to the Company to be bound by and subject to the terms and conditions of this Agreement, including the provisions of Subsection 2.11. For the purposes of determining the number of shares of Registrable Securities held by a transferee, the holdings of a transferee (1) that is an Affiliate or stockholder of a Holder; (2) who is a Holder’s Immediate Family Member; or (3) that is a trust for the benefit of an individual Holder or such Holder’s Immediate Family Member shall be aggregated together and with those of the transferring Holder; provided further that all transferees who would not qualify individually for assignment of rights shall have a single attorney-in-fact for the purpose of exercising any rights, receiving notices, or taking any action under this Agreement. The terms and conditions of this Agreement inure to the benefit of and are binding upon the respective successors and permitted assignees of the parties. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors and permitted assignees any rights, remedies, obligations or liabilities under or by reason of this Agreement, except as expressly provided herein.

6.2 Governing Law. This Agreement shall be governed by the internal law of the State of Delaware without regard to its choice of laws principles.

6.3 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Counterparts may be delivered via facsimile, electronic mail (including pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.

6.4 Titles and Subtitles. The titles and subtitles used in this Agreement are for convenience only and are not to be considered in construing or interpreting this Agreement.

6.5 Notices. All notices and other communications given or made pursuant to this Agreement shall be in writing and shall be deemed effectively given upon the earlier of actual receipt or (i) personal delivery to the party to be notified; (ii) when sent, if sent by electronic mail or facsimile during the recipient’s normal business hours, and if not sent during normal business hours, then on the recipient’s next business day; (iii) five days after having been sent by registered or certified mail, return receipt requested, postage prepaid; or (iv) one (1) business day after the business day of deposit with a nationally recognized overnight courier, freight prepaid, specifying next-day delivery, with written verification of receipt. All communications shall be sent to the respective parties at their addresses as set forth on Schedule A hereto or to such email address, facsimile number, or address as subsequently modified by written notice given in accordance with this Subsection 6.5. If notice is given to the Company, it shall be sent to Senti Biosciences, Inc., 2 Corporate Drive, First Floor, South San Francisco, California 94080, Attn: President, and a copy (which shall not constitute notice) shall also be sent to Cooley LLP, 3175 Hanover Street Palo Alto, CA 94304, Attention: Michael E. Tenta, email mtenta@cooley.com, and if notice is given to the Investors, a copy (which shall not constitute notice) shall also be given to Orrick, Herrington & Sutcliffe LLP, 405 Howard Street, San Francisco, CA 94105, Attention: Ramy Shweiky and via e-mail to rshweiky@orrick.com and to Fenwick & West LLP, 555 California Street, 12^th Floor, San Francisco, CA 94104, Attention: Michael Brown and via e-mail to mbrown@fenwick.com.

6.6 Amendments and Waivers. Any term of this Agreement may be amended and the observance of any term of this Agreement may be waived (either generally or in a particular instance, and either retroactively or prospectively) only with the written consent of the Company and the holders of a majority of the Registrable Securities then outstanding; provided that the Company may in its sole discretion waive compliance with Subsection 2.12(c); provided further that any provision hereof may be waived by any waiving party on such party’s own behalf, without the consent of any other party. Notwithstanding the foregoing, (a) this Agreement may not be amended, modified or terminated and the observance of any term hereof may not be waived with respect to any Investor without the written consent of such Investor, unless such amendment, modification, termination, or waiver applies to all Investors in the same fashion (it being agreed that a waiver of the provisions of Section 4 with respect to a particular transaction shall be deemed to apply to all Investors in the same fashion if such waiver does so by its terms, notwithstanding the fact that certain Investors may nonetheless, by agreement with the Company, purchase securities in such transaction) and (b) Sections 3.1 and 3.2, Section 4 and any other section of this Agreement applicable to the Major Investors may be amended, modified, termination or waived with only the written consent of the Company and the holders of at least 60% of the Registrable Securities then outstanding and held by the Major Investors. Notwithstanding the foregoing, Schedule A hereto may be amended by the Company from time to time without the consent of the other parties hereto (i) to add information regarding transferees of any Registrable Securities in accordance with the terms of this Agreement and (ii) to add information regarding any additional Investor who becomes a party to this Agreement in accordance with Subsection 6.10. The Company shall give prompt notice of any amendment, modification or termination hereof or waiver hereunder to any party hereto that did not consent in writing to such amendment, modification, termination, or waiver. Any amendment, modification, termination, or waiver effected in accordance with this Subsection 6.7 shall be binding on all parties hereto, regardless of whether any such party has consented thereto. No waivers of or exceptions to any term, condition, or provision of this Agreement, in any one or more instances, shall be deemed to be or construed as a further or continuing waiver of any such term, condition, or provision.

6.7 Severability. In case any one or more of the provisions contained in this Agreement is for any reason held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality, or unenforceability shall not affect any other provision of this Agreement, and such invalid, illegal, or unenforceable provision shall be reformed and construed so that it will be valid, legal, and enforceable to the maximum extent permitted by law.

6.8 Aggregation of Stock. All shares of Registrable Securities held or acquired by Affiliates shall be aggregated together for the purpose of determining the availability of any rights under this Agreement and such Affiliated persons may apportion such rights as among themselves in any manner they deem appropriate.

6.9 Additional Investors. Notwithstanding anything to the contrary contained herein, if the Company issues additional shares of Preferred Stock after the date hereof, whether pursuant to the Purchase Agreement or otherwise, any recipient of such shares of Preferred Stock may become a party to this Agreement (without need for amendment or consent) by executing and delivering an additional counterpart signature page to this Agreement, and thereafter shall be deemed an “Investor” for all purposes hereunder. No action or consent by the Investors shall be required for such joinder to this Agreement by such additional Investor, so long as such additional Investor has agreed in writing to be bound by all of the obligations as an “Investor” hereunder.

6.10 Entire Agreement. This Agreement (including the Schedules and Exhibits hereto), the Restated Certificate and the other Transaction Agreements (as defined in the Purchase Agreement) constitute the full and entire understanding and agreement among the parties with respect to the subject matter hereof, and any other written or oral agreement relating to the subject matter hereof existing between the parties is expressly canceled, including, for purposes of clarity, all provisions relating to the subject matter hereof contained in the Prior Agreement. Upon the effectiveness of this Agreement, the Prior Agreement shall be deemed amended and restated and superseded and replaced in its entirety by this Agreement, and shall be of no further force or effect.

6.11 Dispute Resolution. The parties (a) hereby irrevocably and unconditionally submit to the jurisdiction of the state courts of California and to the jurisdiction of the United States District Court for the Northern District of California for the purpose of any suit, action or other proceeding arising out of or based upon this Agreement, (b) agree not to commence any suit, action or other proceeding arising out of or based upon this Agreement except in the state courts of California or the United States District Court for the Northern District of California, and (c) hereby waive, and agree not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court.

WAIVER OF JURY TRIAL: EACH PARTY HEREBY WAIVES ITS RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT, THE OTHER TRANSACTION DOCUMENTS, THE SECURITIES OR THE SUBJECT MATTER HEREOF OR THEREOF. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL-ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE FILED IN ANY COURT AND THAT RELATE TO THE SUBJECT MATTER OF THIS TRANSACTION, INCLUDING, WITHOUT LIMITATION, CONTRACT CLAIMS, TORT CLAIMS (INCLUDING NEGLIGENCE), BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW AND STATUTORY CLAIMS. THIS SECTION HAS BEEN FULLY DISCUSSED BY EACH OF THE PARTIES HERETO AND THESE PROVISIONS WILL NOT BE SUBJECT TO ANY EXCEPTIONS. EACH PARTY HERETO HEREBY FURTHER WARRANTS AND REPRESENTS THAT SUCH PARTY HAS REVIEWED THIS WAIVER WITH ITS LEGAL COUNSEL, AND THAT SUCH PARTY KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL.

Each of the parties to this Agreement consents to personal jurisdiction for any equitable action sought in the U.S. District Court for the Northern District of California or any court of the State of California having subject matter jurisdiction.

6.12 Delays or Omissions. No delay or omission to exercise any right, power, or remedy accruing to any party under this Agreement, upon any breach or default of any other party under this Agreement, shall impair any such right, power, or remedy of such nonbreaching or nondefaulting party, nor shall it be construed to be a waiver of or acquiescence to any such breach or default, or to any similar breach or default thereafter occurring, nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. All remedies, whether under this Agreement or by law or otherwise afforded to any party, shall be cumulative and not alternative.

INVESTMENT LETTER

To: Senti Biosciences, Inc.

Re:

Purchase of Common Stock

Ladies and Gentlemen:

This investment letter is executed and delivered to Senti Biosciences, Inc., a Delaware corporation (the “Company”), in connection with my purchase of shares of common stock of the Company, par value $0.0001 per share (the “Shares”).

The Shares are being purchased pursuant to my exercise of an option granted to me under the Company’s 2016 Stock Incentive Plan (the “Plan”) and pursuant to an [Incentive/Non-Statutory] Stock Option Agreement dated (the “Option Agreement”).

I understand that the Shares have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or registered or qualified under the securities or “blue sky” laws of any state or jurisdiction, and are being sold to me pursuant to exemptions contained in the Securities Act and exemptions contained in other applicable securities or “blue sky” laws. I represent and warrant that the offer and sale of the Shares was made solely in the state shown in the address set forth below. I hereby represent to the Company, and agree that the Company is entitled to rely on such representations, that I am acquiring the Shares with no intention of reselling any of them in any distribution within the meaning of the Securities Act. Specifically, I represent to the Company (i) that I am acquiring the Shares for my own account, and only with a view to investment in, and not for, in connection with or with a view to the disposition of, the Shares, (ii) that no one else has any beneficial ownership in the Shares, (iii) that the Shares are not subject to any pledge or other lien, and (iv) that I do not intend to and will not resell the Shares unless, at a future date, they are registered under the Securities Act or a specific exemption from registration is available to me in connection with such resale. The nature and amount of my investment in the Shares are consistent with my investment objectives, abilities and resources. I understand that the Shares are an illiquid investment, which will not become freely transferable by reason of any “change of circumstances” whatsoever. I have adequate means of providing for my current needs and possible contingencies and have no need for liquidity in my investment.

I understand that the Shares will constitute “restricted securities” within the meaning of Rule l44 promulgated under the Securities Act and that, as such, the Shares must be held indefinitely unless they are subsequently registered under the Securities Act or unless an exemption from the registration requirements thereof is available.

I hereby acknowledge and agree that (i) the Shares shall continue to be bound by the terms and conditions of the Option Agreement and the terms of the Plan, and (ii) in addition to any restrictions on transfer pursuant to any applicable law, the Share are and will remain subject to restrictions on transfer imposed pursuant to the Plan and the Option Agreement. Without limiting the generality of the foregoing, I acknowledge that the Shares shall be subject to that certain right of first refusal in favor of the Company which is described in the Option Agreement.

I acknowledge and agree that in addition to legends required or permitted pursuant to the Plan and the Option Agreement, the certificate representing the Shares will bear a legend in substantially the following form:

“THE SHARES OF STOCK REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 OR UNDER THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE PLEDGED, HYPOTHECATED, SOLD OR OTHERWISE TRANSFERRED UNLESS SUCH SHARES HAVE BEEN REGISTERED UNDER THE ACT OR UNLESS THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY, IN FORM AND SUBSTANCE SATISFACTORY TO THE COMPANY, THAT SUCH REGISTRATION IS NOT REQUIRED.

“ANY DISPOSITION OF ANY INTEREST IN THE SECURITIES REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO RESTRICTIONS, AND THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN OPTIONS, CONTAINED IN A CERTAIN AGREEMENT BETWEEN THE RECORD HOLDER HEREOF AND THE COMPANY, A COPY OF WHICH WILL BE MAILED TO ANY HOLDER OF THIS CERTIFICATE WITHOUT CHARGE UPON RECEIPT BY THE COMPANY OF A WRITTEN REQUEST THEREFOR.”

I acknowledge and agree that the Company may place a stop order pertaining to the certificates evidencing the Shares with any transfer agent of the Company, to the same effect as the above legend. The legend and stop transfer notice referred to above shall be removed only upon my furnishing to the Company an opinion of counsel to the effect that such legend may lawfully be removed and if such counsel and such opinion are satisfactory to the Company.

I have consulted my attorney or my accountant with respect to my purchase of the Shares. My representatives and I have fully investigated the Company and its business and financial conditions and have knowledge of the Company’s current corporate activities and financial condition. I acknowledge that the Company has granted me and my attorney or accountant access to all information about the Company which I have requested and has offered each of us access to all further information which I deemed relevant to an investment decision with respect to the Shares. My attorney or accountant and I have had the opportunity to ask questions of, and receive answers from, representatives of the Company concerning such information and the Company’s financial condition and prospects.

Very truly yours,

This Option is and shall be subject in every respect to the provisions of the Company’s 2016 Stock Incentive Plan, as amended from time to time (the “Plan”), which is incorporated herein by reference and made a part hereof. The holder of this Option (the “Holder”) hereby accepts this Option subject to all the terms and provisions of the Plan and agrees that (a) in the event of any conflict between the terms hereof and those of the Plan, the latter shall prevail, and (b) all decisions under and interpretations of the Plan by the Board or the Committee shall be final, binding and conclusive upon the Holder and his or her heirs and legal representatives.


1.		Name of Holder:	as described on Carta

2.		Date of Grant:	as described on Carta

3.		Maximum number of shares for
	which this Option is exercisable:	as described on Carta

4.		Exercise (purchase) price per share:
		as described on Carta

5.	Method of Exercise: This Option may be exercised by the delivery of written notice to the Company setting forth the number of shares with respect to which the Option is to be exercised, together with payment by one of the following methods:

cash or a personal, certified or bank check or postal money order payable to the order of the Company for an amount equal to the exercise price of the shares being purchased; or

with the consent of the Company, any of the other methods set forth in the Plan.

As an additional condition to exercise of this Option, the Holder shall deliver to the Company an investment letter in form and substance satisfactory to the Company and its counsel. No such investment letter shall be required as a condition to such exercise at any time when there shall be an effective registration statement under the Securities Act of 1933, as amended (the “Act”) covering the shares for which this Option may be exercised.

6.	Expiration Date of Option: as described on Carta

Vesting Schedule: This Option shall become exercisable for 25% of the maximum number of shares granted on the first anniversary of the Date of Grant, and shall become exercisable for an additional 2.08331/3% of the maximum number of shares granted on the last day of each one month period thereafter; so that the Option shall be fully vested on the fourth anniversary of the Date of Grant. All vesting shall cease upon the date of termination of employment.

8.	Termination of Employment. This Option shall terminate on the earliest to occur of:

(i)

the date of expiration hereof;

(ii)

0 days after termination of the Holder’s employment with the Company by the Company for Cause (as defined in the Plan);

(iii)

90 days after the date of voluntary termination of employment by the Holder (other than for death or permanent and total disability as defined in the Plan);

(iv)

90 days after the date of termination of the Holder’s employment with the Company by the Company without Cause (other than for death or permanent and total disability as defined in the Plan); or

(v)

one year after the “permanent and total disability” (as defined at Section 10 of the Plan) or death of the Holder.

6.	Company’s Right of First Refusal. Prior to the effective date of a registration statement under the Act, any shares of stock issued pursuant to exercise of this Option shall be subject to the Company’s right of first refusal as set forth at Appendix A.

Lock-Up Agreement. The Holder agrees that upon the request of the Company or the managing underwriter(s) of any offering of securities of the Company that is the subject of a registration statement filed under the Act, for a period of time (not to exceed 180 days) from the effective date of the registration statement under the Act for such offering, the Holder will not sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any shares of Common Stock issued pursuant to the exercise of this Option, without the prior written consent of the Company and such underwriters.

Incentive Stock Option; Disqualifying Disposition. Although this Option is intended to qualify as an incentive stock option under the Internal Revenue Code of 1986 (the “Code”), the Company makes no representation as to the tax treatment upon exercise of this Option or sale or other disposition of the shares covered by this Option, and the Holder is advised to consult a personal tax advisor. Upon a Disqualifying Disposition of shares received upon exercise of this Option, the Holder will forfeit the favorable income tax treatment otherwise available with respect to the exercise of this Option. A “Disqualifying Disposition” shall have the meaning specified in Section 421(b) of the Code; as of the date of grant of this Option a Disqualifying Disposition is any disposition (including any sale) of such shares before the later of (a) the second anniversary of the date of grant of this Option and (b) the first anniversary of the date on which the Holder acquired such shares by exercising this Option, provided that such holding period requirements terminate upon the death of the Holder. The Holder shall notify the Company in writing immediately upon making a Disqualifying Disposition of any shares of Common Stock received pursuant to the exercise of this Option, and shall provide the Company with any information that the Company shall request concerning any such Disqualifying Disposition.

Voting Agreement. Reference is made to that certain Voting Agreement, dated January 9, 2018, by and among the Company and the other parties thereto, as may be amended or amended and restated from time to time (the “Voting Agreement”). As a condition precedent to the Company being obligated to issue shares of Common Stock upon exercise of this Option, the Holder shall become a party to the Voting Agreement by executing the Adoption Agreement (Voting) attached hereto as Exhibit A , whereby Holder agrees to be bound by and subject to the terms and provisions of such Voting Agreement as a Stockholder (as defined therein) and thereafter Holder shall be deemed a “Stockholder” for all purposes under the Voting Agreement.

10.

Notice. Any notice to be given to the Company hereunder shall be deemed sufficient if addressed to the Company and delivered to the office of the Company, Senti Biosciences, Inc., 2 Corporate Drive, 1st Floor, South San Francisco, CA 94080, attention of the president, or such other address as the Company may hereafter designate.

Any notice to be given to the Holder hereunder shall be deemed sufficient if addressed to and delivered in person to the Holder at his or her address furnished to the Company or when deposited in the mail, postage prepaid, addressed to the Holder at such address.

IN WITNESS WHEREOF, the parties have executed this Option, or caused this Option to be executed, as of the Date of Grant.


SENTI BIOSCIENCES, INC.

By:

The undersigned Holder hereby acknowledges receipt of a copy of the Plan and this Option (including Appendix A hereto), and agrees to the terms of this Option and the Plan.

Holder

APPENDIX A

Right of First Refusal

1. General. Prior to the effective date of a registration statement under the Securities Act of 1933, as amended (the “Act”), covering any shares of the Company’s Common Stock and until such time as the Company shall have effected a public offering of its Common Stock registered under the Act, in the event that, at any time when the Holder (which term for purposes of this section shall mean the Holder and his or her executors, administrators and any other person to whom this Option may be transferred by will or the laws of descent and distribution) is permitted to do so, the Holder desires to sell, assign or otherwise transfer any of the shares issued upon the exercise of this Option, the Holder shall first offer such shares to the Company by giving written notice of the Holder’s desire so to sell, assign or transfer such shares.

2. Notice of Intended Transfer. The notice shall state the number of shares offered, the name of the person or persons to whom it is proposed to sell, assign or transfer such shares and the price at which such shares are intended to be sold, assigned or transferred. Such notice shall constitute an offer to the Company for the Company to purchase the number of shares set forth in the notice at a price per share equal to the price stated therein.

3. Company to Accept or Decline Within 30 Days. The Company may accept the offer as to all, but not less than all, such shares by notifying the Holder in writing within 30 days after receipt of such notice of its acceptance of the offer. If the offer is accepted, the Company shall have 60 days after such acceptance within which to purchase the offered shares at a price per share as aforesaid. If within the applicable time periods the Holder does not receive notice of the Company’s intention to purchase the offered shares, or if payment in full of the purchase price is not made by the Company, the offer shall be deemed to have been rejected and the Holder may transfer title to such shares within 90 days from the date of the Holder’s written notice to the Company of the Holder’s intention to sell, but such transfer shall be made only to the proposed transferee and at the proposed price as stated in such notice and after compliance with any other provisions of this Option applicable to the transfer of such shares.

4. Transferred Shares to Remain Subject to Right of First Refusal. Shares that are so transferred to such transferee shall remain subject to the rights of the Company set forth in this Appendix A. As a condition to such transfer, such transferee shall execute and deliver all such documents as the Company may require to evidence the binding agreement of such transferee so to remain subject to the rights of the Company.

5. Remedies of Company. No sale, assignment, pledge or other transfer of any of the shares covered by this Option shall be effective or given effect on the books of the Company unless all of the applicable provisions of this Appendix A have been duly complied with, and the Company may inscribe on the face of any certificate representing any of such shares a legend referring to the provisions of this Appendix A. If any transfer of shares is made or attempted in violation of the foregoing restrictions, or if shares are not offered to the Company as required hereby, the Company shall have the right to purchase such shares from the owner thereof or his transferee at any time before or after the transfer, as herein provided. In addition to any other legal or equitable remedies which it may have, the Company may enforce its rights by actions for specific performance (to the extent permitted by law) and may refuse to recognize any transferee as one of its stockholders for any purpose, including, without limitation, for purposes of dividend and voting rights, until all applicable provisions hereof have been complied with.

6. Shares Subject to Right of First Refusal. For purposes of the Right of First Refusal pursuant to this Appendix A, the term “shares” shall mean any and all new, substituted or additional securities or other property issued to the Holder, by reason of his or her ownership of Common Stock pursuant to the exercise of this Option, in connection with any stock dividend, liquidating dividend, stock split or other change in the character or amount of any of the outstanding securities of the Company, or any consolidation, merger or sale of all or substantially all of the assets of the Company.

7. Legends on Stock Certificates. Any certificate representing shares of stock subject to the provisions of this Appendix A may have endorsed thereon one or more legends, substantially as follows:

(i)

“Any disposition of any interest in the securities represented by this certificate is subject to restrictions, and the securities represented by this certificate are subject to certain options, contained in a certain agreement between the record holder hereof and the Company, a copy of which will be mailed to any holder of this certificate without charge upon receipt by the Company of a written request therefor.”

(ii)

“The shares of stock represented by this certificate have not been registered under the Securities Act of 1933 or under the securities laws of any state and may not be pledged, hypothecated, sold or otherwise transferred unless such shares have been registered under the Act or unless the Company has received an opinion of counsel satisfactory to the Company, in form and substance satisfactory to the Company, that such registration is not required.”

3. Right of First Refusal to Lapse Upon Registration. The restrictions imposed by this Appendix A shall terminate in all respects upon the effective date of a registration statement under the Act covering any of the Company’s Common Stock.

2016 STOCK INCENTIVE PLAN

ADOPTED BY THE BOARD OF DIRECTORS: JULY 25, 2016

APPROVED BY THE STOCKHOLDERS: JULY 28, 2016

AMENDED BY THE BOARD OF DIRECTORS: FEBRUARY 9, 2018

APPROVED BY THE STOCKHOLDERS: FEBRUARY 9, 2018

APPROVED BY THE STOCKHOLDERS: APRIL 4, 2021

AMENDED BY THE BOARD OF DIRECTORS: DECEMBER 19, 2021

Purpose.

The purpose of this plan (the “Plan”) is to secure for Senti Biosciences, Inc., a Delaware corporation (the “Company”) and its shareholders the benefits arising from capital stock ownership by employees, officers and directors of, and consultants or advisors to, the Company and its parent and subsidiary corporations who are expected to contribute to the Company’s future growth and success. Under the Plan recipients may be awarded both (i) Options (as defined in Section 2.1) to purchase the Company’s common stock, par value $0.0001 (“Common Stock”) and (ii) shares of Common Stock (“Restricted Stock Awards”). Except where the context otherwise requires, the term “Company” shall include any parent and all present and future subsidiaries of the Company as defined in Sections 424(e) and 424(f) of the Internal Revenue Code of 1986, as amended or replaced from time to time (the “Code”). Those provisions of the Plan which make express reference to Section 422 of the Code shall apply only to Incentive Stock Options (as that term is defined below). Appendix A to this Plan shall apply only to participants in the Plan who are residents of the State of California.

Types of Awards and Administration.

2.1 Options. Options granted pursuant to the Plan (“Options”) shall be authorized by action of the Board of Directors of the Company (the “Board” or “Board of Directors”) and may be either incentive stock options (“Incentive Stock Options”) meeting the requirements of Section 422 of the Code or non-statutory Options which are not intended to meet the requirements of Section 422. All Options when granted are intended to be non-statutory Options, unless the applicable Option Agreement (as defined in Section 5.1) explicitly states that the Option is intended to be an Incentive Stock Option. The vesting of Options may be conditioned upon the completion of a specified period of employment with the Company and/or such other conditions or events as the Board may determine. The Board may also provide that Options are immediately exercisable subject to certain repurchase rights in the Company dependent upon the continued employment of the optionee and/or such other conditions or events as the Board may determine.

2.1.1 Incentive Stock Options. Incentive Stock Options may only be granted to employees of the Company. For so long as the Code shall so provide, Options granted to any employee under the Plan (and any other incentive stock option plans of the Company) which are intended to constitute Incentive Stock Options shall not constitute Incentive Stock Options to the extent that such Options, in the aggregate, become exercisable for the first time in any one calendar year for shares of Common Stock with an aggregate fair market value (determined as of the respective date or dates of grant) of more than $100,000. If an Option is intended to be an Incentive Stock Option, and if for any reason such Option (or any portion thereof) shall not qualify as an Incentive Stock Option, then, to the extent of such nonqualification, such Option (or portion thereof) shall be regarded as a non-statutory Option appropriately granted under the Plan provided that such Option (or portion thereof) otherwise meets the Plan’s requirements relating to non-statutory Options.

2.2 Restricted Stock Awards. The Board in its discretion may grant Restricted Stock Awards, entitling the recipient to acquire, for a purchase price determined by the Board, shares of Common Stock subject to such restrictions and conditions as the Board may determine at the time of grant (“Restricted Stock”), including continued employment and/or achievement of pre-established performance goals and objectives.

2.3 Administration. The Plan shall be administered by the Board, whose construction and interpretation of the terms and provisions of the Plan shall be final and conclusive. The Board may in its sole discretion authorize issuance of Restricted Stock, the grant of Options and the issuance of shares upon exercise of such Options as provided in the Plan. The Board shall have authority, subject to the express provisions of the Plan, to construe Restricted Stock Agreements, Option Agreements and the Plan, to prescribe, amend and rescind rules and regulations relating to the Plan, to determine the terms and provisions of Restricted Stock Agreements and Option Agreements, and to make all other determinations in the judgment of the Board necessary or desirable for the administration of the Plan. The Board may correct any defect or supply any omission or reconcile any inconsistency in the Plan or in any Restricted Stock Agreement or Option Agreement in the manner and to the extent it shall deem expedient to carry the Plan into effect and it shall be the sole and final judge of such expediency. No director or person acting pursuant to authority delegated by the Board shall be liable for any action or determination under the Plan made in good faith. The Board may, to the full extent permitted by or consistent with applicable laws or regulations, delegate any or all of its powers under the Plan to a committee (the “Committee”) appointed by the Board, and if the Committee is so appointed, to the extent of such delegation, all references to the Board in the Plan shall mean and relate to such Committee, other than references to the Board in this sentence and in Section 18 (as to amendment or termination of the Plan) and Section 22.

Eligibility.

Options may be granted, and Restricted Stock may be issued, to persons who are, at the time of such grant or issuance, employees, officers or directors of, or consultants or advisors to, the Company; provided, that the class of persons to whom Incentive Stock Options may be granted shall be limited to employees of the Company.

3.1 10% Shareholder. If any employee to whom an Incentive Stock Option is to be granted is, at the time of the grant of such Option, the owner of stock possessing more than 10% of the total combined voting power of all classes of stock of the Company (after taking into account the attribution of stock ownership rules of Section 424(d) of the Code) (a “Greater Than 10% Shareholder”), any Incentive Stock Option granted to such individual must: (i) have an exercise price per share of not less than 110% of the fair market value of one share of Common Stock at the time of grant; and (ii) expire by its terms not more than five years from the date of grant.

Stock Subject to Plan.

Subject to adjustment as provided in Section 14.2 below, the maximum number of shares of Common Stock which may be issued under the Plan is 65,551,165 shares, all of which may be issued with respect to Incentive Stock Options. If an Option shall expire or terminate for any reason without having been exercised in full, the unpurchased shares subject to such Option shall again be available for subsequent Option grants or Restricted Stock Awards under the Plan. If shares of Restricted Stock shall be forfeited to, or otherwise repurchased by, the Company pursuant to a Restricted Stock Agreement, such repurchased shares shall again be available for subsequent Option grants or Restricted Stock Awards under the Plan. If shares otherwise issuable upon exercise of an Option are withheld by the Company in payment of the exercise price of an Option or to satisfy tax withholding obligations with respect to such exercise, such withheld shares shall again be available for subsequent Option grants or Restricted Stock Awards under the Plan.

Forms of Restricted Stock Agreements and Option Agreements.

5.1 Option Agreement. Each recipient of an Option shall execute an option agreement (“Option Agreement”) in such form not inconsistent with the Plan as may be approved by the Board of Directors. Such Option Agreements may differ among recipients.

5.2 Restricted Stock Agreement. Each recipient of a grant of Restricted Stock shall execute an agreement (“Restricted Stock Agreement”) in such form not inconsistent with the Plan as may be approved by the Board of Directors. Such Restricted Stock Agreements may differ among recipients.

5.3 “Lock-Up” Agreement. Unless the Board specifies otherwise, each Restricted Stock Agreement and Option Agreement shall provide that upon the request of the Company or the managing underwriter(s) of any offering of securities of the Company that is the subject of a registration statement filed under the United States Securities Act of 1933, as amended from time to time (the “Act”), the holder of any Option or the purchaser of any Restricted Stock shall, in connection therewith, agree in writing (in such form as the Company or such managing underwriter(s) shall request) to the general effect that for a period of time (not to exceed 180 days) from the effective date of the registration statement under the Act for such offering, the holder or purchaser will not sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any shares of the common stock of the Company owned or controlled by him or her.

Purchase Price.

6.1 General. The purchase price per share of Restricted Stock and per share of stock deliverable upon the exercise of an Option shall be determined by the Board, provided, however, that in the case of any Option, the exercise price shall not be less than 100% of the fair market value of such stock, as determined by the Board, at the time of grant of such Option, or less than 110% of such fair market value in the case of any Incentive Stock Option granted to a Greater Than 10% Shareholder.

6.2 Payment of Purchase Price. Option Agreements may provide for the payment of the exercise price by delivery of cash or a check to the order of the Company in an amount equal to the exercise price of such Options, or, to the extent provided in the applicable Option Agreement, by one of the following methods:

(i) with the consent of the Board, by delivery to the Company of shares of Common Stock; such surrendered shares shall have a fair market value equal in amount to the exercise price of the Options being exercised,

(ii) with the consent of the Board, a personal recourse note issued by the optionee to the Company in a principal amount equal to such aggregate exercise price and with such other terms, including interest rate and maturity, as the Company may determine in its discretion; provided, however, that the interest rate borne by such note shall not be less than the lowest applicable federal rate, as defined in Section 1274(d) of the Code,

(iii) with the consent of the Board, if the class of Common Stock is registered under the Securities Exchange Act of 1934 at such time, subject to rules as may be established by the Board, by delivery to the Company of a properly executed exercise notice along with irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the Company for the purchase price,

(iv) with the consent of the Board, by reducing the number of Option shares otherwise issuable to the optionee upon exercise of the Option by a number of shares of Common Stock having a fair market value equal to such aggregate exercise price,

(v) with the consent of the Board, by any combination of such methods of payment.

The fair market value of any shares of Common Stock or other non-cash consideration which may be delivered upon exercise of an Option shall be determined by the Board of Directors. Restricted Stock Agreements may provide for the payment of any purchase price in any manner approved by the Board of Directors at the time of authorizing the issuance thereof.

Option Period.

Notwithstanding any other provision of the Plan or any Option Agreement, each Option and all rights thereunder shall expire on the date specified in the applicable Option Agreement, provided that such date shall not be later than ten years after the date on which the Option is granted (or five years in the case of an Incentive Stock Option granted to a Greater Than 10% Shareholder), and in either case, shall be subject to earlier termination as provided in the Plan or Option Agreement.

Exercise of Options.

8.1 General. Each Option shall be exercisable either in full or in installments at such time or times and during such period as shall be set forth in the Option Agreement evidencing such Option, subject to the provisions of the Plan. To the extent not exercised, installments shall accumulate and be exercisable, in whole or in part, at any time after becoming exercisable, but not later than the date the Option expires.

8.2 Notice of Exercise. An Option may be exercised by the optionee by delivering to the Company on any business day a written notice specifying the number of shares of Common Stock the optionee then desires to purchase and specifying the address to which the certificates for such shares are to be mailed (the “Notice”), accompanied by payment for such shares. In addition, the Company may require any individual to whom an Option is granted, as a condition of exercising such Option, to give written assurances (the “Investment Letter”) in a substance and form satisfactory to the Company to the effect that such individual is acquiring the Common Stock subject to the Option for his or her own account for investment and not with a view to the resale or distribution thereof, and to such other effects as the Company deems necessary or advisable in order to comply with any securities law(s).

8.3 Delivery. As promptly as practicable after receipt of the Notice, the Investment Letter (if required) and payment, the Company shall deliver or cause to be delivered to the optionee certificates for the number of shares with respect to which such Option has been so exercised, issued in the optionee’s name; provided, however, that such delivery shall be deemed effected for all purposes when the Company or a stock transfer agent shall have deposited such certificates in the United States mail, addressed to the optionee, at the address specified in the Notice.

Nontransferability of Options.

No Option shall be assignable or transferable by the person to whom it is granted, either voluntarily or by operation of law, except by will or the laws of descent and distribution. During the life of an optionee, an Option shall be exercisable only by the optionee.

10. Termination of Employment; Disability; Death. Except as may be otherwise expressly provided in the terms and conditions of the Option Agreement, Options shall terminate on the earliest to occur of:

(i)

the date of expiration thereof;

(ii)

0 days after termination of the optionee’s employment with, or provision of services to, the Company by the Company for Cause (as hereinafter defined);

(iii)

90 days after the date of voluntary termination of the optionee’s employment with, or provision of services to, the Company by the optionee (other than for death or permanent disability as defined below); or

(iv)

90 days after the date of termination of the optionee’s employment with, or provision of services to, the Company by the Company without Cause (other than for death or permanent disability as defined below).

Until the date on which the Option so expires, the optionee may exercise that portion of his or her Option which is exercisable at the time of termination of the employment or service relationship.

An employment or service relationship between the Company and the optionee shall be deemed to exist during any period during which the optionee is employed by or providing services to the Company. Whether an authorized leave of absence or an absence due to military or government service shall constitute termination of the employment relationship between the Company and the optionee shall be determined by the Board at the time thereof.

For purposes of this Section 10, the term “Cause” shall mean (a) any material breach by the optionee of any agreement to which the optionee and the Company are both parties, (b) any act (other than retirement) or omission to act by the optionee which may have a material and adverse effect on the Company’s business or on the optionee’s ability to perform services for the Company, including, without limitation, the commission of any crime (other than minor traffic violations), or (c) any material misconduct or material neglect of duties by the optionee in connection with the business or affairs of the Company. An optionee’s employment shall be deemed to have been terminated for Cause if the Company determines within thirty (30) days of the termination of employment (whether such termination was voluntary or involuntary) that termination for Cause was warranted.

In the event of the permanent and total disability or death of an optionee while in an employment or other relationship with the Company, any Option held by such optionee shall terminate on the earlier of the date of expiration of the Option or one year following the date of such disability or death. After disability or death, the optionee (or in the case of death, his or her executor, administrator or any person or persons to whom this option may be transferred by will or by laws of descent and distribution) shall have the right, at any time prior to such termination

of an Option , to exercise the Option to the extent the optionee was entitled to exercise such Option as of the date of his or her disability or death. An optionee is permanently and totally disabled if he or she is unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to last for a continuous period of not less than 12 months; permanent and total disability shall be determined in accordance with Section 22(e)(3) of the Code and the regulations issued thereunder.

5. Rights as a Shareholder. The holder of an Option shall have no rights as a shareholder with respect to any shares covered by the Option (including, without limitation, any rights to receive dividends or non-cash distributions with respect to such shares) until the date of issue of a stock certificate to him or her for such shares. No adjustment shall be made for dividends or other rights for which the record date is prior to the date such stock certificate is issued.

6. Additional Provisions. The Board of Directors may, in its sole discretion, include additional provisions in Restricted Stock Agreements and Option Agreements, including, without limitation, restrictions on transfer, rights of the Company to repurchase shares of Restricted Stock or shares of Common Stock acquired upon exercise of Options, commitments to pay cash bonuses, to make, arrange for or guaranty loans or to transfer other property to optionees upon exercise of Options, or such other provisions as shall be determined by the Board of Directors; provided that such additional provisions shall not be inconsistent with any other term or condition of the Plan and such additional provisions shall not be such as to cause any Incentive Stock Option to fail to qualify as an Incentive Stock Option within the meaning of Section 422 of the Code.

7. Acceleration, Extension, Etc. The Board of Directors may, in its sole discretion, (i) accelerate the date or dates on which all or any particular Option or Options may be exercised or (ii) extend the period or periods of time during which all, or any particular, Option or Options may be exercised.

Adjustment Upon Changes in Capitalization

14.1 No Effect of Options upon Certain Corporate Transactions. The existence of outstanding Options shall not affect in any way the right or power of the Company to make or authorize any or all adjustments, recapitalizations, reorganizations or other changes in the Company’s capital structure or its business, or any merger or consolidation, or any issue of Common Stock, or any issue of bonds, debentures, preferred or prior preference stock ahead of or affecting the Common Stock or the rights thereof, or the dissolution or liquidation of the Company, or any sale or transfer of all or any part of its assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise.

14.2 Adjustment Provisions. If, through or as a result of any merger, consolidation, sale of all or substantially all of the assets of the Company, reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar transaction, (i) the outstanding shares of Common Stock are increased, decreased or exchanged for a different number or kind of shares or other securities of the Company, or (ii) additional shares or new or different shares or other securities of the Company or other non-cash assets are distributed with respect to such shares of Common Stock or other securities, an appropriate and proportionate adjustment shall be made in (x) the maximum number and kind of shares reserved for issuance under the Plan, (y) the number and kind of shares or other securities subject to any then outstanding Options, and (z) the price for each share or other security subject to any then outstanding Options, so that upon exercise of such Options, in lieu of the shares of Common Stock for which such Options were then exercisable, the relevant optionee shall be entitled to receive, for the same aggregate consideration, the same total number and kind of shares or other securities, cash or property that the owner of an equal number of outstanding shares of Common Stock immediately prior to the event requiring adjustment would own as a result of the event. If any such event shall occur, appropriate adjustment shall also be made in the application of the provisions of this Section 14 and Section 15 with respect to Options and the rights of optionees after the event so that the provisions of such Sections shall be applicable after the event and be as nearly equivalent as practicable in operation after the event as they were before the event.

14.3 No Adjustment in Certain Cases. Except as hereinbefore expressly provided, the issue by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, for cash or property or for labor or services, either upon direct sale or upon the exercise of rights or warrants to subscribe therefor, or upon conversion of shares or obligations of the Company convertible into such shares or other securities, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock then subject to outstanding options.

14.4 Board Authority to Make Adjustments. Any adjustments under this Section 14 will be made by the Board of Directors, whose determination as to what adjustments, if any, will be made and the extent thereof will be final, binding and conclusive. No fractional shares will be issued under the Plan on account of any such adjustments.

15.

Effect of Certain Transactions

15.1 General. Except as provided in any Option Agreement or Restricted Stock Agreement to the contrary, if the Company is merged with or into or consolidated with another corporation under circumstances where the stockholders of the Company immediately prior to such merger or consolidation do not own after such merger or consolidation shares representing at least fifty percent (50%) of the voting power of the Company or the surviving or resulting corporation, as the case may be, or if shares representing fifty percent (50%) or more of the voting power of the Company are transferred to an Unrelated Third Party, as hereinafter defined, or if the Company is liquidated, or sells or otherwise disposes of all or substantially all its assets (each such transaction is referred to herein as a “Change in Control Transaction”), the Board, or the board of directors of any corporation assuming the obligations of the Company, may, in its discretion, take any one or more of the following actions, as to some or all outstanding Options or Restricted Stock Awards (and need not take the same action as to each such Option or Restricted Stock Award): (i) provide that such Options shall be assumed, or equivalent Options shall be substituted, by the acquiring or succeeding corporation (or an affiliate thereof), provided that any such Options substituted for Incentive Stock Options shall meet the requirements of

Section 424(a) of the Code, (ii) upon written notice to the optionees, provide that all unexercised Options (whether vested or unvested) will terminate immediately prior to the consummation of the Change in Control Transaction unless exercised by the optionee to the extent otherwise then exercisable within a specified period following the date of such notice, (iii) upon written notice to the grantees, provide that all unvested shares of Restricted Stock shall be repurchased at cost, (iv) make or provide for a cash payment to the optionees equal to the difference between (A) the fair market value of the per share consideration (whether cash, securities or other property or any combination of the above) the holder of a share of Common Stock will receive upon consummation of the Change in Control Transaction (the “Per Share Transaction Price”) times the number of shares of Common Stock subject to outstanding vested Options (to the extent then exercisable at prices not equal to or in excess of the Per Share Transaction Price) and (B) the aggregate exercise price of such outstanding vested Options, in exchange for the termination of such Options, or (v) provide that all or any outstanding Options shall become exercisable and all or any outstanding Restricted Stock Awards shall vest in part or in full immediately prior to such event. To the extent that any Options are exercisable at a price equal to or in excess of the Per Share Transaction Price, the Board may provide that such Options shall terminate immediately upon the consummation of the Change in Control Transaction without any payment being made to the holders of such Options. “Unrelated Third Party” shall mean any person who is not, on the date of adoption of this Plan by the Board, a holder of stock of any class or preference or any stock option of the Company.

15.2 Substitute Options. The Company may grant Options in substitution for options held by employees, officers or directors of, or consultants or advisors to, another corporation who become employees, officers or directors of, or consultants or advisors to, the Company, as the result of a merger or consolidation of the employing corporation with the Company or as a result of the acquisition by the Company of property or stock of the employing corporation. The Company may direct that substitute Options be granted on such terms and conditions as the Board considers appropriate in the circumstances.

15.3 Restricted Stock. In the event of a business combination or other transaction of the type detailed in Section 15.1, any securities, cash or other property received in exchange for shares of Restricted Stock shall continue to be governed by the provisions of any Restricted Stock Agreement pursuant to which they were issued, including any provision regarding vesting, and such securities, cash, or other property may be held in escrow on such terms as the Board of Directors may direct, to insure compliance with the terms of any such Restricted Stock Agreement.

16. No Special Employment Rights. Nothing contained in the Plan or in any Option Agreement or Restricted Stock Agreement shall confer upon any optionee or holder of Restricted Stock any right with respect to the continuation of his or her employment by the Company or interfere in any way with the right of the Company at any time to terminate such employment or to increase or decrease his or her compensation.

17. Other Employee Benefits. The amount of any compensation deemed to be received by an employee as a result of the issuance of shares of Restricted Stock or the grant or exercise of an Option or the sale of shares received upon issuance of a Restricted Stock Award or exercise of an Option will not constitute compensation with respect to which any other employee benefits of such employee are determined, including, without limitation, benefits under any bonus, pension, profit-sharing, life insurance or salary continuation plan, except as otherwise specifically determined by the Board of Directors.

18.

Amendment of the Plan.

18.1 The Board may at any time, and from time to time, modify or amend in any respect or terminate the Plan. If shareholder approval is not obtained within twelve months after any amendment increasing the number of shares authorized under the Plan or changing the class of persons eligible to receive Options under the Plan, no Options granted pursuant to such amendments shall be deemed to be Incentive Stock Options and no Incentive Stock Options shall be issued pursuant to such amendments thereafter.

18.2 The termination or any modification or amendment of the Plan shall not, without the consent of an optionee or the holder of Restricted Stock, adversely affect his or her rights under an Option or Restricted Stock Award previously granted to him or her. With the consent of the recipient of Restricted Stock or optionee affected, the Board may amend outstanding Restricted Stock Agreements or Option Agreements in a manner not inconsistent with the Plan.

19. Withholding. The Company shall have the right to deduct from payments of any kind otherwise due to the optionee or recipient of Restricted Stock, any federal, state or local taxes of any kind required by law to be withheld with respect to issuance of any shares of Restricted Stock or shares issued upon exercise of Options. Prior to delivery of any Common Stock pursuant to the terms of this Plan, the Board has the right to require that the optionee or recipient of Restricted Stock remit to the Company an amount sufficient to satisfy any minimum tax withholding obligation. Subject to the prior approval of the Company, which may be withheld by the Company in its sole discretion, the obligor may elect to satisfy any minimum withholding obligations, in whole or in part, (i) by causing the Company to withhold shares of Common Stock otherwise issuable, or (ii) by delivering to the Company a sufficient number of shares of Common Stock. The shares so withheld shall have a fair market value equal to such minimum withholding obligation. The fair market value of the shares used to satisfy such minimum withholding obligation shall be determined by the Company as of the date that the amount of tax to be withheld is to be determined. A person who has made an election pursuant to this Section 19 may only satisfy his or her withholding obligation with shares of Common Stock which are not subject to any repurchase, forfeiture, unfulfilled vesting or other similar restrictions.

20.

Effective Date and Duration of the Plan.

20.1 Effective Date. The Plan shall become effective when adopted by the Board of Directors. If shareholder approval is not obtained within twelve months after the date of the Board’s adoption of the Plan, no Options previously granted under the Plan shall be deemed to be Incentive Stock Options and no Incentive Stock Options shall be granted thereafter. Amendments to the Plan not requiring shareholder approval shall become effective when adopted by the Board. Amendments requiring shareholder approval shall become effective when adopted by the Board, but if shareholder approval is not obtained within twelve months of the Board’s adoption of such amendment, any Incentive Stock Options granted pursuant to such amendment shall be deemed to be non-statutory Options provided that such Options are authorized by the Plan. Subject to this limitation, Options may be granted under the Plan at any time after the effective date and before the date fixed for termination of the Plan.

20.2 Termination. Unless sooner terminated by action of the Board of Directors, the Plan shall terminate upon the close of business on the day next preceding the tenth anniversary of the date of its adoption by the Board of Directors.

21. Provision for Foreign Participants. The Board of Directors may, without amending the Plan, modify the terms of Option Agreements or Restricted Stock Agreements to differ from those specified in the Plan with respect to participants who are foreign nationals or employed outside the United States to recognize differences in laws, rules, regulations or customs of such foreign jurisdictions with respect to tax, securities, currency, employee benefit or other matters.

22. Requirements of Law. The Company shall not be required to sell or issue any shares under any Option or Restricted Stock Award if the issuance of such shares shall constitute a violation by the optionee, the Restricted Stock Award recipient, or by the Company of any provision of any law or regulation of any governmental authority. In addition, in connection with the Act, the Company shall not be required to issue any shares upon exercise of any Option unless the Company has received evidence satisfactory to it to the effect that the holder of such Option will not transfer such shares except pursuant to a registration statement in effect under the Act or unless an opinion of counsel satisfactory to the Company has been received by the Company to the effect that such registration is not required in connection with any such transfer. Any determination in this connection by the Board shall be final, binding and conclusive. In the event the shares issuable on exercise of an Option are not registered under the Act or under the securities laws of each relevant state or other jurisdiction, the Company may imprint on the certificate(s) appropriate legends that counsel for the Company considers necessary or advisable to comply with the Act or any such state or other securities law. The Company may register, but in no event shall be obligated to register, any securities covered by the Plan pursuant to the Act; and in the event any shares are so registered the Company may remove any legend on certificates representing such shares. The Company shall not be obligated to take any affirmative action in order to cause the exercise of an Option, the grant of any Restricted Stock Award or the issuance of shares pursuant thereto to comply with any law or regulation of any governmental authority.

23. Conversion of Incentive Stock Options into Non-Qualified Options; Termination. The Board of Directors, with the consent of any optionee, may in its discretion take such actions as may be necessary to convert such optionee’s Incentive Stock Options (or any installments or portions of installments thereof) that have not been exercised on the date of conversion into non-statutory Options at any time prior to the expiration of such Incentive Stock Options, regardless of whether the optionee is an employee of the Company or a parent or

subsidiary of the Company at the time of such conversion. At the time of such conversion, the Board of Directors (with the consent of the optionee) may impose such conditions on the exercise of the resulting non-statutory Options as the Board of Directors in its discretion may determine, provided that such conditions shall not be inconsistent with this Plan. Nothing in this Plan shall be deemed to give any optionee the right to have such optionee’s Incentive Stock Options converted into non-statutory Options, and no such conversion shall occur until and unless the Board of Directors takes appropriate action. The Board of Directors, with the consent of the optionee, may also terminate any portion of any Incentive Stock Option that has not been exercised at the time of such termination.

24. Non-Exclusivity of this Plan; Non-Uniform Determinations. Neither the adoption of this Plan by the Board of Directors nor the approval of this Plan by the stockholders of the Company shall be construed as creating any limitations on the power of the Board of Directors to adopt such other incentive arrangements as it may deem desirable, including, without limitation, the granting of stock options otherwise than under this Plan, and such arrangements may be either applicable generally or only in specific cases.

The determinations of the Board of Directors under this Plan need not be uniform and may be made by it selectively among persons who receive or are eligible to receive Options or Restricted Stock Awards under this Plan (whether or not such persons are similarly situated). Without limiting the generality of the foregoing, the Board of Directors shall be entitled, among other things, to make non-uniform and selective determinations, and to enter into non-uniform and selective Option Agreements and Restricted Stock Agreements, as to (a) the persons to receive Options or Restricted Stock Awards under this Plan, (b) the terms and provisions of Options or Restricted Stock Awards, (c) the exercise by the Board of Directors of its discretion in respect of the exercise of Options pursuant to the terms of this Plan, and (d) the treatment of leaves of absence pursuant to Section 10 hereof.

25. Governing Law. This Plan and each Option or Restricted Stock Award shall be governed by the laws of the state of Delaware, without regard to its principles of conflicts of law.

Re: Offer of Employment

Dear Tim:

As you are aware, you had previously been providing services to Senti Biosciences, Inc. (the “Company”) pursuant to the Consulting Agreement entered into with the Company, dated July 1, 2016 (the “Consulting Agreement”). The Company is pleased to now offer you employment as the Company’s Chief Executive Officer (“CEO”) on the terms and conditions set forth in this letter agreement (the “Agreement”).

1. Commencement of Employment. Your employment with the Company as CEO commenced February 9, 2018, and this Agreement shall become effective on December 24, 2018 (the “Effective Date”).

2. Duties. As CEO, you will be responsible for the general management of the affairs of the Company and will report to the Board of Directors (the “Board”). You shall devote your best efforts and full business time, skill and attention to the performance of your duties. You will also be expected to adhere to the general employment policies and practices of the Company that may be in effect from time to time, except that when the terms of this Agreement conflict with the Company’s general employment policies or practices, this Agreement will control. You will work out of the Company’s offices in South San Francisco, California. The Company may change your position, duties, work location and compensation from time to time in its discretion, subject to the terms and conditions set forth herein.

3. Salary. You will be paid an annual base salary of $400,000, less applicable deductions and withholdings, to be paid in accordance with the Company’s payroll practices, as may be in effect from time to time. Your base salary shall be reviewed annually by the Company’s Board of Directors (the “Board”), commencing in January 2019, and may be adjusted by the Company after each such review after discussions between the Company and you.

Benefits.

(a) Vacation, Holiday, and Sick Time. You shall be entitled to paid vacation, holidays, and sick days in accordance with the Company’s normal policies in effect from time to time.

(b) Benefit Plans. Subject to any contribution generally required of employees of the Company, commencing on the Effective Date, you shall be entitled to participate in any and all employee benefit plans from time to time in effect for full-time executive employees of the Company. Such participation shall be subject to: (i) the terms of the applicable plan documents; and (ii) generally applicable Company policies. Additional information regarding these benefits is available for your review upon request. The Company may, from time to time, change these benefits in its discretion.

(c) Signing Bonus. The Company will pay you a signing bonus of $168,333.33 on or prior to December 31, 2018.

5. Equity. The Company had previously issued to you 8,100,000 shares of the Company’s Common Stock (the “Shares”) pursuant to that certain Restricted Stock Purchase Agreement, dated July 1, 2016 (the “Stock Agreement”). The Shares will continue to be subject to the provisions of the Stock Agreement including, without limitation, provisions relating to accelerated vesting of the Shares upon certain events. You are eligible to receive additional equity under any equity award plan the Company adopts in the future.

6. Annual Performance Bonus. Each year, you will be eligible to earn an annual performance bonus with an annual target amount of up to 40% of your annual base salary, less applicable payroll deductions and withholdings, during the applicable bonus year (the “Annual Bonus”). For the avoidance of doubt, your annual performance bonus for 2018 will be determined by reference to the base salary specified in Section 3 and not by reference to your compensation prior to the Effective Date. Whether you receive such a bonus, and the amount of any such bonus, shall be determined by the Board in its sole discretion, and shall be based upon achievement of performance objectives to be determined by the Company at the beginning of each calendar year (after consultation with you) and the Company’s attainment of goals with such goals as determined annually by the Board. No amount of the Annual Bonus is guaranteed, and you must be an employee on the Annual Bonus payment date in order to earn an Annual Bonus. Therefore, subject to Section 8(c) of this Agreement, if your employment is terminated either by you or the Company for any reason prior to the bonus being paid, you will not have earned the bonus and no partial or prorated bonus will be paid. The Annual Bonus, if earned, will be paid 90 days following the completion of the applicable bonus year.

7. Expenses. The Company shall pay or reimburse you for all reasonable business expenses incurred or paid by you in connection with your employment by the Company in accordance with the Company’s policies in effect from time to time.

8. At Will Employment; Severance Benefits.

(a) At-Will Employment. Your employment with the Company will be “at- will.” This means that either you or Company may terminate your employment at any time, with or without Cause (as defined herein), and with or without advance notice. Upon termination of your employment for any reason, the Company shall pay you all earned but unpaid salary, all earned and unpaid bonus payments, and all accrued but unused vacation earned by you through and including the employment termination date, subject to required payroll deductions, in accordance with governing law. You will not be eligible to receive any Severance Benefits, except as expressly provided in this Agreement.

(b) Termination For Cause; Death; Disability; Resignation Without Good Reason. If, at any time, the Company terminates your employment for Cause, or if either party terminates your employment as a result of your death or disability, or if you resign without Good Reason (as defined herein), you will receive your base salary accrued through your last day of employment, as well as any unused vacation accrued through your last day of employment. Under these circumstances, you will not be entitled to any other form of compensation from the Company, including any Severance Benefits (as defined herein).

(c) Termination Without Cause or Resignation for Good Reason. If, at any time: (i) the Company terminates your employment without Cause, or you resign for Good Reason, provided such termination or resignation constitutes a Separation from Service (as defined under Treasury Regulation Section 1.409A-1(h), without regard to any alternative definition thereunder, a “Separation from Service”); and (ii) you are providing services as CEO as of the Separation from Service date; then subject to your compliance with the terms of this Agreement, the Company will provide you with the following severance benefits (the “Severance Benefits”):

(i) Cash Severance. You will receive cash severance equal to twelve (12) months of your then current base salary as of the Separation from Service date (the “Cash Severance”). The Cash Severance will be paid in equal installments on the Company’s regular payroll schedule and will be subject to applicable tax withholdings over the period outlined above following the date of your termination date, provided, however, that no payments will be made prior to the 60th day following your Separation from Service and in accordance with Section 8(c)(iv) of this Agreement.

(ii) Bonus Severance. You will receive an additional cash severance payment, less applicable deductions and withholdings, equal to the amount of your target annual bonus for the calendar year in which your employment is terminated pursuant to Section 6 of this Agreement, prorated based on the number of days in which your employment termination occurred and if such termination occurs after the applicable bonus year but before the bonus payment date, you will receive your full target bonus for the applicable year (the “Bonus Severance”). The Bonus Severance will be paid in a lump sum pursuant to Section 8(c)(iv) of this Agreement.

(iii) COBRA Severance. If you timely elect continued coverage under COBRA, the Company will continue to pay the cost of your health care coverage in effect at the time of your employment termination for a maximum of twelve (12) months (the “COBRA Severance”). The Company’s obligation to pay the COBRA Severance on your behalf will cease if you obtain health care coverage from another source (e.g., a new employer or spouse’s benefit plan), unless otherwise prohibited by applicable law. Notwithstanding the above, if the Company determines in its sole discretion that it cannot provide the foregoing COBRA Severance without potentially violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), the Company shall in lieu thereof provide to you a taxable monthly payment in an amount equal to the monthly COBRA premium that you would be required to pay to continue your group health coverage in effect on the date of your termination (which amount shall be based on the premium for the first month of COBRA coverage), which payments shall be made on the last day of each month regardless of whether you elect COBRA continuation coverage and shall end on the earlier of (x) the date upon which you obtain other employment or (y) the last day of the third calendar month following your Separation from Service date.

(iv) Payment Timing. On the 60th day following your Separation from Service, the Company will pay you in a lump sum the Cash Severance, Bonus Severance, and other Severance Benefits that you would have received on or prior to such date under the original schedule but for the delay while waiting for the 60th day in compliance with Code Section 409A and the effectiveness of the Release (as defined herein), with the balance of the Cash Severance and other Severance Benefits being paid as originally scheduled.

(d) Termination Without Cause or Resignation for Good Reason in Connection with a Change in Control. If: (i) the Company consummates a Change in Control (as defined herein); and (ii) your employment is terminated by the Company without Cause (as defined herein) or if you resign from the Company for Good Reason (as defined herein), in either case within three (3) months before a Change in Control or within twelve (12) months after a Change in Control; then effective as of your employment termination date, 100% of your then remaining unvested Shares shall become fully vested (the “Accelerated Vesting”).

(e) Conditions to Receipt of Severance. Your receipt of the Severance Benefits and Accelerated Vesting under Sections 8(c) and 8(d) of this Agreement is conditioned upon: (i) you continuing to comply with your obligations under your Confidential Information and Inventions Agreement; and (ii) you delivering to the Company an effective, general release of claims in favor of the Company substantially in the form attached hereto as Exhibit A (the “Release”) within the applicable time period set forth therein.

10. Section 409A. It is intended that all of the severance benefits and other payments payable under this letter satisfy, to the greatest extent possible, the exemptions from the application of Code Section 409A provided under Treasury Regulations 1.409A-1(b)(4), 1.409A-1(b)(5) and 1.409A-1(b)(9), and this letter will be construed to the greatest extent possible as consistent with those provisions. For purposes of Code Section 409A (including, without limitation, for purposes of Treasury Regulation Section 1.409A-2(b)(2)(iii)), your right to receive any installment payments under this letter (whether severance payments, reimbursements or otherwise) shall be treated as a right to receive a series of separate payments and, accordingly, each installment payment hereunder shall at all times be considered a separate and distinct payment. Notwithstanding any provision to the contrary in this letter, if you are deemed by the Company at the time of your Separation from Service to be a “specified employee” for purposes of Code Section 409A(a)(2)(B)(i), and if any of the payments upon Separation from Service set forth herein and/or under any other agreement with the Company are deemed to be “deferred compensation”, then to the extent delayed commencement of any portion of such payments is required in order to avoid a prohibited distribution under Code Section 409A(a)(2)(B)(i) and the related adverse taxation under Section 409A, such payments shall not be provided to you prior to the earliest of (i) the expiration of the six-month period measured from the date of your Separation from Service with the Company, (ii) the date of your death or (iii) such earlier date as permitted under Section 409A without the imposition of adverse taxation. Upon the first business day following the expiration of such applicable Code Section 409A(a)(2)(B)(i) period, all payments deferred pursuant to this paragraph shall be paid in a lump sum to you, and any remaining payments due shall be paid as otherwise provided herein or in the applicable agreement. No interest shall be due on any amounts so deferred.

11. Confidentiality and Intellectual Property Obligations; Obligations with respect to Massachusetts Institute of Technology. As condition of your employment, you must sign and abide by the Company’s standard form of Confidential Information and Inventions Agreement, a copy of which is attached hereto as Exhibit B. You represent and agree that the execution, delivery and performance of this Agreement, including the Confidential Information and Inventions Agreement, does not and will not conflict with any other agreement, policy or rule of the Massachusetts Institute of Technology (the “Institution”) or any other third party applicable to you. You represent to the Company and agree as follows:

(a) you have not disclosed to the Company any information that you are or were required to keep secret pursuant to an existing confidentiality agreement with the Institution or any other third party,

(b) you have not used the funding, resources or facilities of the Institution or any other third party in your service to the Company,

(c) you have not performed your services to the Company in any manner that would give the Institution or any other third party rights to any intellectual property created in connection with such services,

(d) you agree not to do or facilitate any of the acts described in (a), (b) or (c) above,

(e) you are currently on professional leave from the Institution,

(g) you agree not to change your status with the Institution to a status that could reasonably be expected to require a greater commitment of your professional time than the “professional leave” status you have as of the Effective Date without the prior written consent of the Board, which shall not be unreasonably withheld. You may cease providing services to the Institution and commence providing services to another institution of higher education; provided, however, that you may not commence a status requiring a greater commitment of your professional time than the “professional leave” status you have with the Institution as of the Effective Date without the prior written consent of the Board, which shall not be unreasonably withheld.

12. Arbitration. To ensure the timely and economical resolution of disputes that may arise in connection with your employment with the Company, you and the Company agree that any and all disputes, claims, or causes of action arising from or relating to the enforcement, breach, performance, negotiation, execution, or interpretation of this Agreement, your employment, or the termination of your employment, including but not limited to statutory claims, will be resolved to the fullest extent permitted by law by final, binding and confidential arbitration, by a single arbitrator, in San Francisco, California, conducted by JAMS, Inc. (“JAMS”) under the then-applicable JAMS rules (available at the following web address: http://www.jamsadr.com/rulesclauses, and which will be provided to you on request). By agreeing to this arbitration procedure, both you and the Company waive the right to resolve any such dispute through a trial by jury or judge or administrative proceeding. You will have the right to be represented by legal counsel at any arbitration proceeding. In addition, all claims, disputes, or causes of action under this section, whether by you or the Company, must be brought in an individual capacity, and shall not be brought as a plaintiff (or claimant) or class member in any purported class or representative proceeding, nor joined or consolidated with the claims of any other person or entity. The arbitrator may not consolidate the claims of more than one person or entity, and may not preside over any form of representative or class proceeding. To the extent that the preceding sentences regarding class claims or proceedings are found to violate applicable law or are otherwise found unenforceable, any claim(s) alleged or brought on behalf of a class shall proceed in a court of law rather than by arbitration. This paragraph shall not apply to an action or claim brought in court pursuant to the California Private Attorneys General Act of 2004, as amended. The arbitrator shall: (a) have the authority to compel adequate discovery for the resolution of the dispute and to award such relief as would otherwise be permitted by law; and (b) issue a written arbitration decision, to include the arbitrator’s essential findings and conclusions and a statement of the award. The arbitrator shall be authorized to award any or all remedies that you or the Company would be entitled to seek in a court of law. The Company shall pay all JAMS’ arbitration fees in excess of the amount of court fees that would be required of you if the dispute were decided in a court of law. Nothing in this letter is intended to prevent either you or the Company from obtaining injunctive relief in court to prevent irreparable harm pending the conclusion of any such arbitration. Any awards or orders in such arbitrations may be entered and enforced as judgments in the federal and state courts of any competent jurisdiction.

Re:

Offer of Employment

Dear Philip:

As you are aware, you had previously been providing services to Senti Biosciences, Inc. (the “Company”) pursuant to the Consulting Agreement entered into with the Company, dated July 1, 2016 (the “Consulting Agreement”). The Company is pleased to now offer you employment as the Company’s Chief Operating Officer (“COO”) on the terms and conditions set forth in this letter agreement (the “Agreement”).

1. Commencement of Employment. Your employment with the Company as COO commenced February 9, 2018, and this Agreement, shall become effective on December 26, 2018 (the “Effective Date”).

2. Duties. As COO, you will have duties and responsibilities customary for a COO and will report to the Company’s Chief Executive Officer. You shall devote your best efforts and full business time, skill and attention to the performance of your duties. You will also be expected to adhere to the general employment policies and practices of the Company that may be in effect from time to time, except that when the terms of this Agreement conflict with the Company’s general employment policies or practices, this Agreement will control. You will work out of the Company’s offices in South San Francisco, California. The Company may change your position, duties, work location and compensation from time to time in its discretion, subject to the terms and conditions set forth herein.

3. Salary. You will be paid an annual base salary of $350,000, less applicable deductions and withholdings, to be paid in accordance with the Company’s payroll practices, as may be in effect from time to time. Your base salary shall be reviewed annually by the Company’s Board of Directors (the “Board”), commencing in January 2019, and may be adjusted by the Company after each such review after discussions between the Company and you.

4. Benefits.

(a) Vacation, Holiday, and Sick Time. You shall be entitled to paid vacation, holidays, and sick days in accordance with the Company’s normal policies in effect from time to time.

Philip Lee

(b) Benefit Plans. Subject to any contribution generally required of employees of the Company, commencing on the Effective Date, you shall be entitled to participate in any and all employee benefit plans from time to time in effect for full-time executive employees of the Company. Such participation shall be subject to: (i) the terms of the applicable plan documents; and (ii) generally applicable Company policies. Additional information regarding these benefits is available for your review upon request. The Company may, from time to time, change these benefits in its discretion.

(c) Signing Bonus. The Company will pay you a signing bonus of $126,666.67 on or prior to December 31, 2018.

5. Equity. The Company had previously issued to you 3,750,000 shares of the Company’s Common Stock (the “Shares”) pursuant to that certain Restricted Stock Purchase Agreement, dated July 1, 2016 (the “Stock Agreement”). The Shares will continue to be subject to the provisions of the Stock Agreement including, without limitation, provisions relating to accelerated vesting of the Shares upon certain events. You are eligible to receive additional equity under any equity award plan the Company adopts in the future.

6. Annual Performance Bonus. Each year, you will be eligible to earn an annual performance bonus with an annual target amount of up to 35% of your annual base salary, less applicable payroll deductions and withholdings, during the applicable bonus year (the “Annual Bonus”). For the avoidance of doubt, your annual performance bonus for 2018 will be determined by reference to the base salary specified in Section 3 and not by reference to your compensation prior to the Effective Date. Whether you receive such a bonus, and the amount of any such bonus, shall be determined by the Board in its sole discretion, and shall be based upon achievement of performance objectives to be determined by the Company at the beginning of each calendar year (after consultation with you) and the Company’s attainment of goals with such goals as determined annually by the Board. No amount of the Annual Bonus is guaranteed, and you must be an employee on the Annual Bonus payment date in order to earn an Annual Bonus. Therefore, subject to Section 8(c) of this Agreement, if your employment is terminated either by you or the Company for any reason prior to the bonus being paid, you will not have earned the bonus and no partial or prorated bonus will be paid. The Annual Bonus, if earned, will be paid 90 days following the completion of the applicable bonus year.

7. Expenses. The Company shall pay or reimburse you for all reasonable business expenses incurred or paid by you in connection with your employment by the Company in accordance with the Company’s policies in effect from time to time.

8. At Will Employment; Severance Benefits.

(a) At-Will Employment. Your employment with the Company will be “at-will.” This means that either you or Company may terminate your employment at any time, with or without Cause (as defined herein), and with or without advance notice. Upon termination of your employment for any reason, the Company shall pay you all earned but unpaid salary, all earned and unpaid bonus payments, and all accrued but unused vacation earned by you through and including the employment termination date, subject to required payroll deductions, in accordance with governing law. You will not be eligible to receive any Severance Benefits, except as expressly provided in this Agreement.

(c) Termination Without Cause or Resignation for Good Reason.

The Bonus Severance will be paid in a lump sum pursuant to Section 8(c)(iv) of this Agreement.

(iii) COBRA Severance. If you timely elect continued coverage under COBRA, the Company will continue to pay the cost of your health care coverage in effect at the time of your employment termination for a maximum of nine (9) months (the “COBRA Severance”).

Notwithstanding the above, if the Company determines in its sole discretion that it cannot provide the foregoing COBRA Severance without potentially violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), the Company shall in lieu thereof provide to you a taxable monthly payment in an amount equal to the monthly COBRA premium that you would be required to pay to continue your group health coverage in effect on the date of your termination (which amount shall be based on the premium for the first month of COBRA coverage), which payments shall be made on the last day of each month regardless of whether you elect COBRA continuation coverage and shall end on the earlier of (x) the date upon which you obtain other employment or (y) the last day of the third calendar month following your Separation from Service date.

By agreeing to this arbitration procedure, both you and the Company waive the right to resolve any such dispute through a trial by jury or judge or administrative proceeding. You will have the right to be represented by legal counsel at any arbitration proceeding. In addition, all claims, disputes, or causes of action under this section, whether by you or the Company, must be brought in an individual capacity, and shall not be brought as a plaintiff (or claimant) or class member in any purported class or representative proceeding, nor joined or consolidated with the claims of any other person or entity. The arbitrator may not consolidate the claims of more than one person or entity, and may not preside over any form of representative or class proceeding. To the extent that the preceding sentences regarding class claims or proceedings are found to violate applicable law or are otherwise found unenforceable, any claim(s) alleged or brought on behalf of a class shall proceed in a court of law rather than by arbitration. This paragraph shall not apply to an action or claim brought in court pursuant to the California Private Attorneys General Act of 2004, as amended. The arbitrator shall: (a) have the authority to compel adequate discovery for the resolution of the dispute and to award such relief as would otherwise be permitted by law; and (b) issue a written arbitration decision, to include the arbitrator’s essential findings and conclusions and a statement of the award. The arbitrator shall be authorized to award any or all remedies that you or the Company would be entitled to seek in a court of law. The Company shall pay all JAMS’ arbitration fees in excess of the amount of court fees that would be required of you if the dispute were decided in a court of law. Nothing in this letter is intended to prevent either you or the Company from obtaining injunctive relief in court to prevent irreparable harm pending the conclusion of any such arbitration. Any awards or orders in such arbitrations may be entered and enforced as judgments in the federal and state courts of any competent jurisdiction.

13. Termination of Consulting Agreement. Upon your written acceptance of this Agreement, you and the Company agree that your consulting relationship with the Company and the Consulting Agreement will immediately terminate, regardless of any notice provisions set forth in the Consulting Agreement, which are hereby waived. You hereby acknowledge that you have been paid all amounts for all time worked and received all compensation and benefits owed to you under your previous Consulting Agreement, and that upon your written acceptance of this Agreement, your entitlement to any compensation or any other payment or benefit under your previous Consulting Agreement shall be terminated and shall have no further force and effect.

FINAL

EXHIBIT A—FORM OF RELEASE

(TO BE SIGNED ON OR WITHIN 21 DAYS OF SEPARATION DATE)

I understand that my position with SENTI BIOSCIENCES, INC. (the “Company”) terminated effective ____________, _____ (the “Separation Date”). The Company has agreed that if I choose to sign this Release, the Company will extend to me certain benefits (minus the standard withholdings and deductions, if applicable) pursuant to the terms of the offer letter agreement (the “Agreement”) entered into as of DATE, between myself and the Company, and any agreements incorporated therein by reference. I understand that I am not entitled to such severance benefits provided in the Agreement unless I sign this Release without revocation. I also understand that, regardless of whether I sign this Release, the Company will pay me all of my accrued salary and vacation through the Separation Date, to which I am entitled by law.

In consideration for the severance benefits I am receiving under the Agreement, I hereby generally release the Company and its officers, directors, agents, attorneys, employees, stockholders, parents, subsidiaries, and affiliates from any and all claims, liabilities, demands, causes of action, attorneys’ fees, damages, or obligations of every kind and nature, whether they are now known or unknown, arising at any time prior to the date I sign this Release. This general release includes, but is not limited to: (i) all federal and state statutory and common law claims, including claims for discrimination, harassment, retaliation, attorneys’ fees, or other claims arising under the federal Civil Rights Act of 1964 (as amended), the federal Americans with Disabilities Act of 1990, the federal Age Discrimination in Employment Act of 1967 (as amended) (“ADEA”), the federal Employee Retirement Income Security Act of 1974 (as amended), the California Labor Code (as amended), and the California Fair Employment and Housing Act (as amended); (ii) claims related to my employment or the termination of my employment; and (iii) claims related to breach of contract, tort, wrongful termination, discrimination, wages or benefits, or claims for any form of equity or compensation.

I acknowledge that I am knowingly and voluntarily waiving and releasing any rights I may have under the ADEA. I also acknowledge that the consideration given for the waiver in this paragraph is in addition to anything of value to which I was already entitled. I have been advised by this writing, as required by the ADEA that: (a) my waiver and release do not apply to any claims that may arise after my signing of this Release; (b) I should consult with an attorney prior to executing this Release; (c) I have twenty-one (21) days within which to consider this Release (although I may choose to voluntarily execute this Release earlier); (d) I have seven (7) days following the execution of this release to revoke the Release; and (e) this Release will not be effective until the eighth day after this Release has been signed by me (“Effective Date”).

Notwithstanding the release in the preceding paragraphs, I am not releasing: (i) any right of indemnification I may have under contract or law, including, without limitation, for any liabilities arising from my actions within the course and scope of my employment with the Company; (ii) any rights which cannot be waived as a matter of law; and (iii) claims for breach of this Release. In addition, I understand that nothing in this Release limits my ability to file a charge or complaint with the Equal Employment

Opportunity Commission, the Department of Labor, the National Labor Relations Board, the Occupational Safety and Health Administration, the Securities and Exchange Commission or any other federal, state or local governmental agency or commission (“Government Agencies”). I further understand that this Release does not limit my ability to communicate with any Government Agencies or otherwise participate in any investigation or proceeding that may be conducted by any Government Agency, including providing documents or other information, without notice to the Company. While this Release does not limit my right to receive an award for information provided to the Securities and Exchange Commission, I understand and agree that, to maximum extent permitted by law, I am otherwise waiving any and all rights I may have to individual relief based on any claims that I have released and any rights I have waived by signing this Release.

In releasing claims unknown to me at present, I am waiving all rights and benefits under Section 1542 of the California Civil Code, and any law or legal principle of similar effect in any jurisdiction: “A general release does not extend to claims which the creditor does not know or suspect to exist in his favor at the time of executing the release, which if known by him must have materially affected his settlement with the debtor.”

I hereby represent that I have been paid all compensation owed and for all hours worked, I have received all the leave and leave benefits and protections for which I am eligible, and I have not suffered any on-the-job injury for which I have not already filed a workers’ compensation claim. I further acknowledge that, other than the severance benefits that will be provided to me pursuant to the Agreement and this Release, I have not earned and will not receive from the Company any additional compensation, severance, or benefits, with the exception of any vested right I may have under the express terms of a written ERISA-qualified benefit plan (e.g., 401(k) account). By way of example, I acknowledge that I have not earned and am not owed any bonus, vacation, incentive compensation, severance, commissions or equity.

I hereby confirm my obligations under my Confidential Information and Inventions Assignment Agreement with the Company.

In addition, I hereby agree to keep the provisions of this Release and the Agreement in strictest confidence and shall not publicize or disclose it in any manner whatsoever; provided, however, that: (a) I may disclose this Release to my immediate family; (b) I may disclose this Release in confidence to my attorneys, accountants, auditors, tax preparers, and financial advisors; and (c) I may disclose this agreement insofar as such disclosure may be necessary to enforce its terms or as otherwise required by law. In particular, and without limitation, I agree not to disclose the terms of this Release to any current or former employee, consultant or independent contractor of the Company.

I also agree that I will not voluntarily (except in response to legal compulsion ) assist any person in bringing or pursuing any proposed or pending litigation, arbitration, administrative claim or other formal proceeding against the Company, its parent or subsidiary entities, affiliates, officers, directors, employees or agents. I further agree to reasonably cooperate with the Company by voluntarily providing accurate and complete information, in connection with the Company’s actual or contemplated defense, prosecution, or investigation of any claims or demands by or against third parties, or other matters, arising from events, acts, or failures to act that occurred during the period of my employment by the Company.

I hereby agree not to disparage the Company, or its officers, directors, employees, shareholders or agents, in any manner likely to be harmful to them or their business, business reputation, or personal reputation; provided, however, that I will respond accurately and fully to any question, inquiry or request for information when required by legal process or in connection with a government investigation. In addition, I understand that nothing in this Release is intended to prohibit or restrain me in any manner from making disclosures that are protected under the whistleblower provisions of federal or state law or regulation.

In addition, Executive will be allowed to be a member of the board of directors for up to two (2) companies, provided that such activities are not competitive to the Company and are approved in advance in writing by the Company, which approval shall not be unreasonably withheld.

(d) No Waiver. The terms and conditions of this Agreement may be waived only by a written instrument signed by the party waiving compliance. In the case of the Company, no waiver shall be effective unless approved by the Board. The failure of any party hereto to enforce at any time any of the provisions of this Agreement shall in no way be construed to be a waiver of any such provision, nor in any way to affect the validity of this Agreement or any part hereof or the right of such party thereafter to enforce each and every such provision.

(g) Governing Law. This Agreement shall be governed by, and construed and enforced in accordance with, the substantive laws of the State of California, without regard to its principles of conflicts of laws.

(h) Arbitration. To ensure the rapid and economical resolution of disputes that might arise in connection with Executive’s employment with the Company, Executive and the Company agree that any and all disputes, claims, or causes of action, in law or equity, arising from or relating to the enforcement or interpretation of this agreement, Executive’s employment or the termination of Executive’s employment (collectively, “Claims”), shall be resolved to the fullest extent permitted by law by final, binding, and (to the extent permitted by law) confidential arbitration in San Francisco, CA conducted by JAMS under the then applicable JAMS employment rules. Claims subject to this arbitration provision shall (a) include, but not be limited to, Claims pursuant to any federal, state or local law or statute, including (without limitation) the Age Discrimination in Employment Act, as amended; Title VII of the Civil Rights Act of 1964, as amended; the Americans With Disabilities Act of 1990; the federal Fair Labor Standards Act; the California Fair Employment and Housing Act; the California Pregnancy Disability Act; and Claims pursuant to any common law, tort law or contract law, including (without limitation) breach of contract or other promise, discrimination, harassment, retaliation, wrongful discharge, fraud, misrepresentation, defamation, and emotional distress, and (b) exclude Claims that by law are not subject to arbitration. The arbitrator shall: (a) have the authority to compel adequate discovery for the resolution of all Claims and to award such relief as would otherwise be permitted by law; and (b) issue a written arbitration decision including the arbitrator s essential findings and conclusions and a statement of the award. The Company shall pay all of the arbitrator’s fees in excess of the amount of those administrative fees Executive would have been required to pay if the Claims were decided in a court of law. Executive and the Company acknowledge that by agreeing to this arbitration procedure, both Executive and the Company waive the right to resolve any Claims through a trial by jury or judge or by administrative proceeding. Nothing in this agreement is intended to prevent either Executive or the Company from obtaining injunctive relief in court to prevent irreparable harm pending the conclusion of any such arbitration.

(i) Remedies. Executive recognizes that money damages alone may not adequately compensate the Company in the event of breach by Executive of this Agreement, and Executive therefore agrees that, in addition to all other remedies available to the Company at law, in equity or otherwise, the Company may be entitled to injunctive relief for the enforcement hereof. All rights and remedies hereunder are cumulative and are in addition to and not exclusive of any other rights and remedies available at law, in equity, by agreement or otherwise. If there is a dispute between the parties regarding this Agreement, the prevailing party in such dispute will be entitled to recover his or its reasonable attorneys’ fees and costs.

(j) Validity. In the event that any provision of this Agreement shall be determined to be unenforceable by reason of its extension for too great a period of time or over too large a geographic area or over too great a range of activities, it shall be interpreted to extend only over the maximum period of time, geographic area or range of activities as to which it may be enforceable. If, after application of the preceding sentence, any provision of this Agreement shall be determined to be invalid, illegal or otherwise unenforceable by an arbitrator and/or court of competent jurisdiction, the validity, legality and enforceability of the other provisions of this Agreement shall not be affected thereby. Except as otherwise provided in this Section 17, any invalid, illegal or unenforceable provision of this Agreement shall be severable, and after any such severance, all other provisions hereof shall remain in full force and effect.

(k) Counterparts. This Agreement may be executed in one or more counterparts, all of which together shall constitute one and the same Agreement.

Re:

Offer of Employment

Dear Deborah:

Senti Biosciences, Inc. (the “Company”) is pleased to offer you employment as the Company’s Chief Financial Officer (“CFO”) on the terms and conditions set forth in this letter agreement (the “Agreement”).

1. Commencement of Employment. Your employment with the Company will commence on May 18, 2021 (the “Effective Date”).

2. Duties. As CFO, you will serve as Principal Accounting Officer (PAO) and Principal Financial Officer (PFO). You will be responsible for Investor Relations, Risk Management, Finance and Accounting, reporting to the Chief Executive Officer. You shall devote your best efforts and full business time, skill and attention to the performance of your duties. You will be expected to adhere to the general employment policies and practices of the Company that may be in effect from time to time, except that when the terms of this Agreement conflict with the Company’s general employment policies or practices, this Agreement will control. You will work out of your home in Denver, Colorado, and will travel to the Company’s offices in South San Francisco, California as needed. The company will not require you to relocate permanently to San Francisco, California and shall reimburse you for all reasonable and properly documented travel expenses between Denver and San Francisco, including airfare, ground transportation, lodging, and meals. The Company may change your position, duties, and compensation from time to time at its discretion, subject to the terms and conditions set forth herein, specifically in reference to the terms set forth in Section 7(d).

3. Compensation.

(a) Base Salary. You will be paid an annual base salary of $400,000, less applicable deductions and withholdings, payable in accordance with the Company’s payroll practices as may be in effect from time to time. Your base salary shall be reviewed annually by the Company’s Board of Directors (the “Board”), commencing in January 2022.

(b) Signing Bonus. The Company will pay you a signing bonus of $40,000. This bonus will be paid within ninety (90) days after the Effective Date, less deductions and withholdings. Although this bonus will be paid at the time of hire, it will not be earned until you have completed fourteen (14) months of employment. Therefore, in the event you resign your employment with the Company without Good Reason (as defined herein) before you complete fourteen (14) months of employment with the Company, then you will be required to repay the entire amount of this bonus to the Company within thirty (30) days after your last day of employment.

(c) Annual Performance Bonus. Each year, you will be eligible to earn an annual performance bonus with an annual target amount of up to 40% of your annual base salary, less applicable payroll deductions and withholdings (the “Annual Bonus”) (to be prorated for 2021 based on the Effective Date). Whether you receive such a bonus, and the amount of any such bonus, shall be determined by the Board in its sole discretion, and shall be based upon achievement of Company and individual performance objectives, with such goals and the attainment of such goals to be determined by the Company in its sole discretion. No amount of the Annual Bonus is guaranteed, and you must be an employee on the last day of the applicable calendar year in order to earn an Annual Bonus. Therefore, subject to Section 7 of this Agreement, if your employment is terminated either by you or the Company for any reason prior to the end of the calendar year, you will not have earned the Annual Bonus and no partial or prorated Annual Bonus will be paid. The Annual Bonus, if earned, will be paid within 90 days following the completion of the applicable bonus year.

4. Benefits. Subject to any contributions generally required of employees of the Company, commencing on the Effective Date, you shall be entitled to participate in any and all employee benefit plans from time to time in effect for full-time executive employees of the Company. Such participation shall be subject to the terms of the applicable plan documents and generally applicable Company policies. Additional information regarding these benefits is available for your review upon request. The Company may, from time to time, change these benefits in its discretion.

5. Equity. Subject to approval by the Board, the Company will grant you an option to purchase 750,000 shares of the Company’s common stock (the “Option”). The Option shall vest over a four-year period, with one quarter (1/4) of the shares subject to the Option vesting on the first anniversary of the Effective Date, and the remaining shares vesting equally over the following thirty-six (36) months of continuous service. The Option shall be issued pursuant to the terms and conditions of the Company’s Equity Incentive Plan (the “Plan”), at an exercise price equal to 100% of the fair market value of the Company’s common stock on the grant date, as provided in the Plan and consistent with the requirements for an exemption from the application of Section 409A of the Internal Revenue Code (the “Code”) and shall be governed in all respects by the terms of the Plan, the grant notices and the option agreements.

6. Expenses. The Company shall pay or reimburse you for all reasonable business expenses incurred or paid by you in connection with your employment by the Company in accordance with the Company’s policies in effect from time to time.

7. At Will Employment; Severance Benefits.

(a) At-Will Employment. Your employment with the Company will be “at- will.” This means that either you or Company may terminate your employment at any time, with or without Cause (as defined herein), and with or without advance notice. Upon termination of your employment for any reason, the Company shall pay you all earned but unpaid salary, and all accrued but unused vacation earned by you through and including the employment termination date, subject to required payroll deductions, in accordance with governing law. You will not be eligible to receive any severance benefits, except as expressly provided in this Agreement.

(b) Termination for Cause; Death; Disability; Resignation Without Good Reason. If, at any time, the Company terminates your employment for Cause, or if either party terminates your employment as a result of your death or disability, or if you resign without Good Reason (as defined herein), you will receive the accrued amounts set forth in Section 7(a) and will not be entitled to any other form of compensation from the Company, including any severance benefits.

(c) Termination Without Cause or Resignation for Good Reason Outside of Change of Control Period. If at any time outside of a Change of Control Period (as defined below), the Company terminates your employment without Cause or you resign for Good Reason, provided such termination or resignation constitutes a Separation from Service (as defined under Treasury Regulation Section 1.409A-1(h), without regard to any alternative definition thereunder, a “Separation from Service”), then subject to your compliance with the terms of this Agreement and subject to the preconditions set forth in Section 7(e), the Company will provide you with the following severance benefits (the “Severance Benefits”):

(i) Cash Severance. You will receive cash severance equal to nine (9) months of your then current base salary. This severance will be paid in equal installments on the Company’s regular payroll schedule over the 9-month period following your Separation from Service and will be subject to applicable tax withholdings; provided, however, that no payments will be made prior to the 60th day following your Separation from Service (and with the first such payment including any amounts accrued following such Separation from Service).

(ii) COBRA Severance. If you timely elect continued coverage under COBRA, the Company will continue to pay the cost of your health care coverage in effect at the time of your employment termination for a maximum of nine (9) months. The Company’s obligation to pay these amounts on your behalf will cease if you obtain health care coverage from another source (e.g., a new employer or spouse’s benefit plan), unless otherwise prohibited by applicable law. Notwithstanding the above, if the Company determines in its sole discretion that it cannot provide these benefits without potentially violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), the Company shall in lieu thereof provide to you a taxable monthly payment in an amount equal to the monthly COBRA premium that you would be required to pay to continue your group health coverage in effect on the date of your termination (which amount shall be based on the premium for the first month of COBRA coverage), which payments shall be made on the last day of each month regardless of whether you elect COBRA continuation coverage and shall end on the earlier of (x) the date upon which you obtain other employment or (y) the same date as (when your COBRA began) of the 9th calendar month following your Separation from Service.

(d) Termination Without Cause or Resignation for Good Reason During Change of Control Period. If at any time during a Change of Control Period (as defined below), the Company terminates your employment without Cause or you resign for Good Reason, provided such termination or resignation constitutes a Separation from Service, then subject to your compliance with the terms of this Agreement and subject to the preconditions set forth in Section 7(e), the Company will provide you with the following severance benefits:

(i) Cash Severance. You will receive cash severance equal to twelve (12) months of your then current base salary, paid in a lump sum, subject to applicable tax withholdings, on the 60th day following your Separation from Service.

(ii) Bonus Severance. You will receive an additional cash severance payment, less applicable deductions and withholdings, equal to the amount of your target annual bonus for the calendar year in which your employment is terminated, paid in a lump on the 60th day following your Separation from Service.

(iii) COBRA Severance. If you timely elect continued coverage under COBRA, the Company will continue to pay the cost of your health care coverage in effect at the time of your employment termination for a maximum of eighteen (18) months. The Company’s obligation to pay these amounts on your behalf will cease if you obtain health care coverage from another source (e.g., a new employer or spouse’s benefit plan), unless otherwise prohibited by applicable law. Notwithstanding the above, if the Company determines in its sole discretion that it cannot provide these benefits without potentially violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), the Company shall in lieu thereof provide to you a taxable monthly payment in an amount equal to the monthly COBRA premium that you would be required to pay to continue your group health coverage in effect on the date of your termination (which amount shall be based on the premium for the first month of COBRA coverage), which payments shall be made on the last day of each month regardless of whether you elect COBRA continuation coverage and shall end on the earlier of (x) the date upon which you obtain other employment or (y) the same date as (when your COBRA began) of the eighteenth calendar month following your Separation from Service.

(iv) Accelerated Vesting. The Company will accelerate the vesting of your equity awards such that you will be deemed fully vested in all such shares as of your Separation from Service.

(e) Conditions to Receipt of Severance. Your receipt of the severance benefits set forth in this Section 7 is conditioned upon: (i) you continuing to comply with your obligations under your Confidential Information and Inventions Agreement; and (ii) you delivering to the Company an effective, general release of claims in favor of the Company substantially in the form attached hereto as Exhibit A (the “Release”) within the applicable time period set forth therein.

8. Definitions.

(a) Cause. For purposes of this Agreement, “Cause” shall mean the occurrence of any of the following: (i) your material breach of this Agreement, (ii) any act or omission by you that has a material and adverse effect on the Company’s business, or on your ability to perform services for the Company, including, without limitation, the commission of any crime (other than minor traffic violations), or (iii) your material misconduct or material neglect of your duties in connection with the business or affairs of the Company; provided, however, that before terminating your employment for Cause, the Company will provide you with 30 days’ advance written notice with the event specifically set forth in the notice and the opportunity to cure the event (if curable).

(b) Change of Control. For purposes of this Agreement, a “Change of Control” shall mean the closing of: (i) a sale of all or substantially all of the assets of the Company; (ii) any consolidation or merger of the Company with or into any other corporation or other entity or person, or any other corporate reorganization, other than any such consolidation, merger or reorganization in which the stockholders of the Company immediately prior to such consolidation, merger or reorganization, continue to hold a majority of the voting power of the surviving entity (or, if the surviving entity is a wholly owned subsidiary, its parent) immediately after such consolidation, merger or reorganization; or (iii) a stock tender or a merger, consolidation or similar event pursuant to a transaction or series of related transactions in which a third party (which term shall include a current stockholder) acquires more than fifty percent (50%) of the equity voting securities of the Company outstanding immediately prior to the consummation of such transaction or series of related transactions, and the shareholders of the Company do not retain a majority of the equity voting securities of the surviving entity, other than (a) a merger, conversion or other transaction the principal goal of which is to change the jurisdiction of incorporation of the Company, or (b) an equity security financing for the account of the Company in which capital stock of the Company is sold to one or more institutional investors. Notwithstanding the foregoing, a transaction or series of transactions shall not constitute a Change of Control unless such transaction or series of transactions also qualifies as a “change in control” event under U.S. Treasury Regulation 1.409A-3(i)(5).

(c) Change of Control Period. For purposes of this Agreement, a “Change of Control Period” is defined as the period commencing three (3) months prior to the effective date of a Change of Control and ending on the twelve (12) month anniversary of the effective date of a Change of Control.

(d) Good Reason. For purposes of this Agreement, “Good Reason” shall mean your resignation because of any of the following actions taken without your consent: (i) the Company’s material breach of any one or more of the material provisions of this Agreement; (ii) a material reduction by the Company of your annual base salary, unless such reduction is applied equally, as a percentage of base salary, to all senior executives of the Company; or (iii) a material adverse change in your duties, authority, or responsibilities relative to your duties, authority, or responsibilities in effect immediately prior to such reduction (other than a change in title and provided that a change in title, reporting lines or position in connection with a Change of Control will not, in itself, be deemed to be a change in duties, authority or responsibility); provided, however, that any such termination by you shall only be deemed for Good Reason pursuant to this definition if: (1) you give the Company written notice of your intent to terminate for Good Reason within ninety (90) days following the first occurrence of the condition(s) that you believe constitute(s) Good Reason, which notice shall describe such condition(s); (2) the Company fails to remedy such condition(s) within thirty (30) days following receipt of the written notice (the “Cure Period”); and (3) you voluntarily terminate your employment within thirty (30) days following the end of the Cure Period.

9. Section 409A. It is intended that all of the severance benefits and other payments payable under this letter satisfy, to the greatest extent possible, the exemptions from the application of Code Section 409A provided under Treasury Regulations 1.409A-1(b)(4), 1.409A-1(b)(5) and 1.409A-1(b)(9), and this letter will be construed to the greatest extent possible as consistent with those provisions. For purposes of Code Section 409A (including, without limitation, for purposes of Treasury Regulation Section 1.409A-2(b)(2)(iii)), your right to receive any installment payments under this letter (whether severance payments, reimbursements or otherwise) shall be treated as a right to receive a series of separate payments and, accordingly, each installment payment hereunder shall at all times be considered a separate and distinct payment. Notwithstanding any provision to the contrary in this letter, if you are deemed by the Company at the time of your Separation from Service to be a “specified employee” for purposes of Code Section 409A(a)(2)(B)(i), and if any of the payments upon Separation from Service set forth herein and/or under any other agreement with the Company are deemed to be “deferred compensation”, then to the extent delayed commencement of any portion of such payments is required in order to avoid a prohibited distribution under Code Section 409A(a)(2)(B)(i) and the related adverse taxation under Section 409A, such payments shall not be provided to you prior to the earliest of (i) the expiration of the six-month period measured from the date of your Separation from Service with the Company, (ii) the date of your death or (iii) such earlier date as permitted under Section 409A without the imposition of adverse taxation. Upon the first business day following the expiration of such applicable Code Section 409A(a)(2)(B)(i) period, all payments deferred pursuant to this paragraph shall be paid in a lump sum to you, and any remaining payments due shall be paid as otherwise provided herein or in the applicable agreement. No interest shall be due on any amounts so deferred.

10. 280G.

(a) If any payment or benefit you will or may receive from the Company or from another source (a “280G Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of Code, and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then any such 280G Payment pursuant to this letter agreement (a “Payment”) will be equal to the Reduced Amount. The “Reduced Amount” will be either (x) the largest portion of the Payment that would result in no portion of the Payment (after reduction) being subject to the Excise Tax or (y) the largest portion, up to and including the total, of the Payment, whichever amount (i.e., the amount determined by clause (x) or by clause (y)), after taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in your receipt, on an after-tax basis, of the greater economic benefit notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction in a Payment is required pursuant to the preceding sentence and the Reduced Amount is determined pursuant to clause (x) of the preceding sentence, the reduction will occur in the manner (the “Reduction Method”) that results in the greatest economic benefit for you. If more than one method of reduction will result in the same economic benefit, the items so reduced will be reduced pro rata (the “Pro Rata Reduction Method”).

(b) Notwithstanding any provision of paragraph (a) to the contrary, if the Reduction Method or the Pro Rata Reduction Method would result in any portion of the Payment being subject to taxes pursuant to Section 409A that would not otherwise be subject to taxes pursuant to Section 409A, then the Reduction Method and/or the Pro Rata Reduction Method, as the case may be, will be modified so as to avoid the imposition of taxes pursuant to Section 409A as follows: (A) as a first priority, the modification will preserve to the greatest extent possible, the greatest economic benefit for you as determined on an after-tax basis; (B) as a second priority, Payments that are contingent on future events (e.g., being terminated without cause), will be reduced (or eliminated) before Payments that are not contingent on future events; and (C) as a third priority, Payments that are “deferred compensation” within the meaning of Section 409A of the Code will be reduced (or eliminated) before Payments that are not deferred compensation within the meaning of Section 409A of the Code.

(c) If you receive a Payment for which the Reduced Amount was determined pursuant to clause (x) of Section 10(a) and the Internal Revenue Service determines thereafter that some portion of the Payment is subject to the Excise Tax, you agree to promptly return to the Company a sufficient amount of the Payment (after reduction pursuant to clause (x) of Section 10(a)) so that no portion of the remaining Payment is subject to the Excise Tax. For the avoidance of doubt, if the Reduced Amount was determined pursuant to clause (y) of Section 10(a), you will have no obligation to return any portion of the Payment pursuant to the preceding sentence.

11. Confidentiality Obligations. As condition of your employment, you must sign and abide by the Company’s standard form of Employee Confidential Information and Invention Assignment Agreement, a copy of which is attached hereto as Exhibit B.

12. Arbitration. To ensure the timely and economical resolution of disputes that may arise between you and the Company, both you and the Company mutually agree that pursuant to the Federal Arbitration Act, 9 U.S.C. §1-16, and to the fullest extent permitted by applicable law, you will submit solely to final, binding and confidential arbitration any and all disputes, claims, or causes of action arising from or relating to: the negotiation, execution, interpretation, performance, breach or enforcement of this letter agreement; or your employment with the Company (including but not limited to all statutory claims); or the termination of your employment with the Company (including but not limited to all statutory claims). BY AGREEING TO THIS ARBITRATION PROCEDURE, BOTH YOU AND THE COMPANY WAIVE THE RIGHT TO RESOLVE ANY SUCH DISPUTES THROUGH A TRIAL BY JURY OR JUDGE OR THROUGH AN ADMINISTRATIVE PROCEEDING. The Arbitrator will have the sole and exclusive authority to determine whether a dispute, claim or cause of action is subject to arbitration under this section and to determine any procedural questions which grow out of such disputes, claims or causes of action and bear on their final disposition. All claims, disputes, or causes of action under this section, whether by you or the Company, must be brought solely in an individual capacity, and will not be brought as a plaintiff (or claimant) or class member in any purported class or representative proceeding, nor joined or consolidated with the claims of any other person or entity. The Arbitrator may not consolidate the claims of more than one person or entity, and may not preside over any form of representative or class proceeding. To the extent that the preceding sentences in this paragraph are found to violate applicable law or are otherwise found unenforceable, any claim(s) alleged or brought on behalf of a class will proceed in a court of law rather than by arbitration. Any arbitration proceeding under this Arbitration section will be presided over by a single arbitrator and conducted by JAMS, Inc. (“JAMS”) in San Francisco, CA under the then applicable JAMS rules for the resolution of employment disputes (available upon request and also currently available at http://www.jamsadr.com/rules-employment-arbitration/). You and the Company both have the right to be represented by legal counsel at any arbitration proceeding, at each party’s own expense. The Arbitrator will: (a) have the authority to compel adequate discovery for the resolution of the dispute; (b) issue a written arbitration decision, to include the arbitrator’s essential findings and conclusions and a statement of the award; and (c) be authorized to award any or all remedies that you or the Company would be entitled to seek in a court of law. The Company will pay all JAMS arbitration fees in excess of the amount of court fees that would be required of you if the dispute were decided in a court of law. This section will not apply to any action or claim that cannot be subject to mandatory arbitration as a matter of law, including, without limitation, claims brought pursuant to the California Private Attorneys General Act of 2004, as amended, the California Fair Employment and Housing Act, as amended, and the California Labor Code, as amended, to the extent such claims are not permitted by applicable law to be submitted to mandatory arbitration and such applicable law is not preempted by the Federal Arbitration Act or otherwise invalid (collectively, the “Excluded Claims”). In the event you intend to bring multiple claims, including one of the Excluded Claims listed above, the Excluded Claims may be filed with a court, while any other claims will remain subject to mandatory arbitration. Nothing in this section is intended to prevent either you or the Company from obtaining injunctive relief in court to prevent irreparable harm pending the conclusion of any such arbitration. Any final award in any arbitration proceeding hereunder may be entered as a judgment in the federal and state courts of any competent jurisdiction and enforced accordingly.

13. Miscellaneous. This Agreement, including its exhibits, is the complete and exclusive statement of all of the terms and conditions of your employment with the Company, and supersedes and replaces any and all prior agreements or representations with regard to the subject matter hereof, whether written or oral. It is entered into without reliance on any promise or representation other than those expressly contained herein, and it cannot be modified, amended or extended except in a writing signed by you and a duly authorized member of the Board. This Agreement is intended to bind and inure to the benefit of and be enforceable by you and the Company, and our respective successors, assigns, heirs, executors and administrators, except that you may not assign any of your duties or rights hereunder without the express written consent of the Company. Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability will not affect any other provision or any other jurisdiction, but this Agreement will be reformed, construed and enforced as if such invalid, illegal or unenforceable provisions had never been contained herein. This Agreement and the terms of your employment with the Company shall be governed in all aspects by the laws of the State of California.

This offer is subject to satisfactory proof of your right to work in the United States and satisfactory completion of a Company-required background check. If you agree to the terms and conditions set forth herein, please sign below.

If you have any questions about this Agreement, please do not hesitate to call me.

Best regards,

EXHIBIT A - FORM OF RELEASE

(TO BE SIGNED ON OR WITHIN 21 DAYS OF SEPARATION DATE)

I understand that my employment with SENTI BIOSCIENCES, INC. (the “Company”) has terminated. The Company has agreed that if I sign this Release, the Company will provide me with the benefits set forth in the offer letter agreement (the “Agreement”) between me and the Company. I understand that I am not entitled to such severance benefits unless I sign this Release without revocation. I also understand that, regardless of whether I sign this Release, the Company will pay me all of my accrued salary and vacation through my last day of employment, to which I am entitled by law.

I hereby generally release the Company and its officers, directors, agents, attorneys, employees, stockholders, parents, subsidiaries, and affiliates from any and all claims, liabilities, demands, causes of action, attorneys’ fees, damages, or obligations of every kind and nature, whether they are now known or unknown, arising at any time prior to the date I sign this Release. This general release includes, but is not limited to: (i) all federal and state statutory and common law claims, including claims for discrimination, harassment, retaliation, attorneys’ fees, or other claims arising under the federal Civil Rights Act of 1964 (as amended), the federal Americans with Disabilities Act of 1990, the federal Age Discrimination in Employment Act of 1967 (as amended) (“ADEA”), the federal Employee Retirement Income Security Act of 1974 (as amended), the California Labor Code (as amended), and the California Fair Employment and Housing Act (as amended); (ii) claims related to my employment or the termination of my employment; and (iii) claims related to breach of contract, tort, wrongful termination, discrimination, wages or benefits, or claims for any form of equity or compensation.

Notwithstanding the release in the preceding paragraphs, I am not releasing: (i) any right of indemnification I may have under contract or law; (ii) any rights that cannot be waived as a matter of law; and (iii) claims for breach of this Release. In addition, I understand that nothing in this Release limits my ability to file a charge or complaint with the Equal Employment Opportunity Commission, the Department of Labor, the National Labor Relations Board, the Occupational Safety and Health Administration, the Securities and Exchange Commission or any other federal, state or local governmental agency or commission (“Government Agencies”). I further understand that this Release does not limit my ability to communicate with any Government Agencies or otherwise participate in any investigation or proceeding that may be conducted by any Government Agency, including providing documents or other information, without notice to the Company. While this Release does not limit my right to receive an award for information provided to the Securities and Exchange Commission, I understand and agree that, to maximum extent permitted by law, I am otherwise waiving any and all rights I may have to individual relief based on any claims that I have released and any rights I have waived by signing this Release.

In releasing claims unknown to me at present, I am waiving all rights and benefits under Section 1542 of the California Civil Code, and any law or legal principle of similar effect in any jurisdiction: “A general release does not extend to claims which the creditor or releasing party does not know or suspect to exist in his favor at the time of executing the release, which if known by him would have materially affected his settlement with the debtor or released party.”

I hereby confirm my obligations under my Confidential Information and Inventions Assignment Agreement with the Company.

I also agree that I will not voluntarily (except in response to legal compulsion) assist any person in bringing or pursuing any proposed or pending litigation, arbitration, administrative claim or other formal proceeding against the Company, its parent or subsidiary entities, affiliates, officers, directors, employees or agents. I further agree to reasonably cooperate with the Company by voluntarily providing accurate and complete information, in connection with the Company’s actual or contemplated defense, prosecution, or investigation of any claims or demands by or against third parties, or other matters, arising from events, acts, or failures to act that occurred during the period of my employment by the Company.

1. PREMISES, BUILDING, PROJECT, AND COMMON AREAS

1.1 Premises, Building, Project and Common Areas.

1.1.1 The Premises. Landlord hereby leases to Tenant and Tenant hereby leases from Landlord the premises set forth in Section 2.2 of the Summary (the “Premises”). The outline of the Premises is set forth in Exhibit A attached hereto. The outline of the “Building” and the “Project,” as those terms are defined in Section 1.1.2 below, are further depicted on the Site Plan attached hereto as Exhibit A-1. The parties hereto agree that the lease of the Premises is upon and subject to the terms, covenants and conditions herein set forth, and Tenant covenants as a material part of the consideration for this Lease to keep and perform each and all of such terms, covenants and conditions by it to be kept and performed and that this Lease is made upon the condition of such performance. The parties hereto hereby acknowledge that the purpose of Exhibit A is to show the approximate location of the Premises only, and such Exhibit is not meant to constitute an agreement, representation or warranty as to the construction of the Premises, the precise area thereof or the specific location of the “Common Areas,” as that term is defined in Section 1.1.3, below, or the elements thereof or of the accessways to the Premises or the “Project,” as that term is defined in Section 1.1.2, below. Except as specifically set forth in this Lease and in the Tenant Work Letter attached hereto as Exhibit B (the “Tenant Work Letter”), Landlord shall not be obligated to provide or pay for any improvement work or services related to the improvement of the Premises. Tenant also acknowledges that neither Landlord nor any agent of Landlord has made any representation or warranty regarding the condition of the Premises, the Building or the Project or with respect to the suitability of any of the foregoing for the conduct of Tenant’s business, except as specifically set forth in this Lease and the Tenant Work Letter. Landlord shall deliver the Premises to Tenant fully decommissioned, in good, vacant, broom clean condition, and otherwise in substantially the same condition as of the date of this Lease, in compliance with all laws, with the roof water-tight and shall cause the backup generator, roof and roof membrane, and the plumbing, electrical systems, fire sprinkler system, lighting, heating, ventilation, air conditioning (“HVAC”) and all other building systems serving the Premises to be in good operating condition and repair , and with all required occupancy permits (or equivalent final permit signoffs) relating to the Base Building, and with Tenant Improvements substantially complete and the Premises “Ready For Occupancy” (as defined in Exhibit B) on or before the Lease Commencement Date. Notwithstanding anything in this Lease to the contrary, in connection with the foregoing Landlord shall, at Landlord’s sole cost and expense (which shall not be deemed an “Operating Expense,” as that term is defined in Section 4.2.4), repair or replace any failed or inoperable portion of the HVAC systems serving the Premises to cause the same to be in good working order and repair during the first three (3) years of the initial Lease term (“Warranty Period”), provided that the need to repair or replace was not caused by the misuse, misconduct, damage, destruction, omissions, and/or negligence of Tenant, its subtenants and/or assignees, if any, or any company which is acquired, sold or merged with Tenant (collectively, “Tenant Damage”), or by any modifications, Alterations or improvements (other than the Tenant Improvements) constructed by or on behalf of Tenant. Landlord shall coordinate such work with Tenant and shall utilize commercially reasonable efforts to perform the same in a manner designed to minimize interference with Tenant’s use of the Premises. To the extent repairs which Landlord is required to make pursuant to this Section 1.1.1 are necessitated in part by Tenant Damage, then Tenant shall reimburse Landlord for an equitable proportion of the cost of such repair. Landlord will be responsible for causing the exterior of the Building, the existing Building entrances, and all Common Areas (including required striping and handicapped spaces in the parking areas) to be in compliance with Applicable Laws, to the extent required to allow the legal occupancy of the Premises or completion of the Tenant Improvements, except to the extent required by permitting of the Tenant Improvements alone.

1.1.2 The Building and The Project. The Premises constitutes the portion of the building set forth in Section 2.1 of the Summary (the “Building”). The Building is part of an office/laboratory project currently known as “Britannia Gateway Business Park.” The term “Project,” as used in this Lease, shall mean (i) the Building and the Common Areas, (ii) the land (which is improved with landscaping, parking facilities and other improvements) upon which the Building and the Common Areas are located, (iii) the other office/laboratory buildings located at Britannia Gateway Business Park, and the land upon which such adjacent office/laboratory buildings are located, and (iv) at Landlord’s discretion, any additional real property, areas, land, buildings or other improvements added thereto outside of the Project (provided that any such additions do not increase Tenant’s obligations under this Lease).

Britannia Biotech Gateway Business Park

[Britannia Gateway Business Park]

[Senti Biosciences, Inc.]

1.1.3 Common Areas. Tenant shall have the non-exclusive right to use in common with other tenants in the Project, and subject to the rules and regulations referred to in Article 5 of this Lease, those portions of the Project which are provided, from time to time, for use in common by Landlord, Tenant and any other tenants of the Project (such areas, together with such other portions of the Project designated by Landlord, in its discretion, are collectively referred to herein as the “Common Areas”). Landlord shall maintain and operate the Common Areas, including all sprinkler and other systems serving the Common Areas, in a first class manner, and the use thereof shall be subject to such reasonable rules, regulations and restrictions as Landlord may make from time to time. Landlord reserves the right to close temporarily, make alterations or additions to, or change the location of elements of the Project and the Common Areas, provided that in connection therewith Landlord will use commercially reasonable efforts to minimize any interference with Tenant’s use of and access to the Premises and parking areas.

1.2 Rentable Square Feet of Premises. The rentable square footage of the Premises is hereby deemed to be as set forth in Section 2.2 of the Summary, and shall not be subject to measurement or adjustment during the Lease Term except due to physical changes to the square footage (e.g. due to casualty or condemnation).

1.3 Beneficial Occupancy of Portion of Premises. Tenant shall have the right to use, access and fully occupy that certain portion of the Premises containing 11,060 rentable square feet of space shown on Exhibit A attached hereto (the “Early Occupancy Premises”) upon the full execution and delivery of this Lease (subject to coordination and scheduling with Landlord and provided the same shall not interfere with Landlord’s construction activities in the Premises and Project, and provided that Tenant occupies such space in its as-is condition and does not make any alterations prior to such occupancy), provided that (A) Tenant shall give Landlord at least five (5) days’ prior notice of any such occupancy of the Early Occupancy Premises, (B) and (B) all of the terms and conditions of the Lease shall apply, other than Tenant’s obligation to pay “Base Rent,” as that term is defined in Article 3 below, (though Tenant shall be required to pay “Tenant’s Share” of the annual “Direct Expenses,” as those terms are defined in Article 4, below and utilities costs for the Early Occupancy Premises during the occupancy thereof), as though the Lease Commencement Date had occurred (although the Lease Commencement Date shall not actually occur until the occurrence of the same pursuant to Section 3.2 of the Summary and the terms of the second sentence of Article 2) upon such occupancy of the Early Occupancy Premises by Tenant. Tenant’s use of the Early Occupancy Premises prior to the Lease Commencement Date shall not result in an occupancy density for the Early Occupancy Premises which is greater than fifty (50) persons in the Early Occupancy Premises.

2. LEASE TERM; OPTION TERM

2.1 Lease Term. The terms and provisions of this Lease shall be effective as of the date of this Lease. The term of this Lease (the “Lease Term”) shall be as set forth in Section 3.1 of the Summary, shall commence on the date set forth in Section 3.2 of the Summary (the “Lease Commencement Date”), and shall terminate on the date set forth in Section 3.3 of the Summary (the “Lease Expiration Date”) unless this Lease is sooner terminated as hereinafter provided. For purposes of this Lease, the term “Lease Year” shall mean each consecutive twelve (12) month period during the Lease Term. At any time during the Lease Term, Landlord may deliver to Tenant a notice in the form as set forth in Exhibit C, attached hereto, as a confirmation only of the information set forth therein, which Tenant shall execute and return to Landlord within fifteen (15) business days of receipt thereof.

2.2 Option Term.

2.2.1 Option Right. Landlord hereby grants to the Tenant originally named in this Lease (the “Original Tenant”), and its “Permitted Assignees”, as that term is defined in Section 14.8, below, one (1) option to extend the Lease Term for a period of eight (8) years (the “Option Term”), which option shall be irrevocably exercised only by written notice delivered by Tenant to Landlord not more than twelve (12) months nor less than nine (9) months prior to the expiration of the initial Lease Term (“Option Exercise Notice”), provided that the following conditions (the “Option Conditions”) are satisfied: (i) as of the date of delivery of such Option Exercise Notice, Tenant is not in default under this Lease, after the expiration of any applicable notice and cure period; (ii) Tenant has not previously been in default under this Lease, after the expiration of any applicable notice and cure period, more than twice in the twelve (12) month period prior to the date of Tenant’s attempted exercise; and (iii) the Lease then remains in full force and effect. Landlord may, at Landlord’s option, exercised in Landlord’s sole and absolute discretion, waive any of the Option Conditions in which case the option, if otherwise properly exercised by Tenant, shall remain in full force and effect. Upon the proper exercise of such option to extend, and provided that Tenant satisfies all of the Option Conditions (except those, if any, which are waived by Landlord), the Lease Term, as it applies to the Premises, shall be extended for a period of eight (8) years. The rights contained in this Section 2.2 shall be personal to Original Tenant and any Permitted Assignees, and may be exercised by Original Tenant or such Permitted Assignees (and not by any other assignee, sublessee or other “Transferee,” as that term is defined in Section 14.1 of this Lease, of Tenant’s interest in this Lease).

[Senti Biosciences, Inc.]

2.2.2 Option Rent. The annual Rent payable by Tenant during the Option Term (the “Option Rent”) shall be equal to the “Fair Rental Value,” as that term is defined below, for the Premises as of the commencement date of the Option Term. The “Fair Rental Value,” as used in this Lease, shall be equal to the annual rent per rentable square foot (including additional rent and considering any “base year” or “expense stop” applicable thereto), including all escalations, at which tenants (pursuant to leases consummated within the twelve (12) month period preceding the first day of the Option Term), are leasing non-sublease, non-encumbered, non-equity space which is not significantly greater or smaller in size than the subject space, with a comparable level of improvements (excluding any property that Tenant would be allowed to remove from the Premises at the termination of the Lease), for a comparable lease term, in an arm’s length transaction, which comparable space is located in the “Comparable Buildings,” as that term is defined in this Section 2.2.2, below (transactions satisfying the foregoing criteria shall be known as the “Comparable Transactions”), taking into consideration all relevant factors, including the following concessions (the “Concessions”): (a) rental abatement concessions, if any, being granted such tenants in connection with such comparable space; (b) tenant improvements or allowances provided or to be provided for such comparable space, and taking into account the value, if any, of the existing improvements in the subject space (other than improvements installed by Tenant at Tenant’s sole cost and expense), such value to be based upon the age, condition, design, quality of finishes and layout of the improvements and the extent to which the same can be utilized by a general office/lab user other than Tenant; and (c) other reasonable monetary concessions being granted such tenants in connection with such comparable space; provided, however, that in calculating the Fair Rental Value, no consideration shall be given to the fact that Landlord is or is not required to pay a real estate brokerage commission in connection with Tenant’s exercise of its right to extend the Lease Term, or the fact that landlords are or are not paying real estate brokerage commissions in connection with such comparable space. The Concessions shall be reflected in the effective rental rate (which effective rental rate shall take into consideration the total dollar value of such Concessions as amortized on a straight-line basis over the applicable term of the Comparable Transaction (in which case such Concessions evidenced in the effective rental rate shall not be granted to Tenant)) payable by Tenant. The term “Comparable Buildings” shall mean the Building and those other life sciences buildings which are comparable to the Building in terms of age (based upon the date of completion of construction or major renovation of to the building), quality of construction, level of services and amenities, size and appearance, and are located in South San Francisco, California and the surrounding commercial area.

2.2.3 Determination of Option Rent. In the event Tenant timely and appropriately exercises its option to extend the Lease Term, Landlord shall notify Tenant of Landlord’s determination of the Option Rent on or before the date that is thirty (30) days following Landlord’s receipt of the Option Exercise Notice. If Tenant, on or before the date which is twenty (20) days following the date upon which Tenant receives Landlord’s determination of the Option Rent objects to Landlord’s determination of the Option Rent, then Landlord and Tenant shall attempt to agree upon the Option Rent using their best good-faith efforts. If Landlord and Tenant fail to reach an agreement within twenty (20) days following Tenant’s objection to the Option Rent (the “Outside Agreement Date”), then Tenant shall have the right to withdraw its exercise of the option by delivering written notice thereof to Landlord within five (5) business days thereafter, in which event Tenant’s right to extend the Lease pursuant to this Section 2.2 shall be of no further force or effect. If Tenant does not withdraw its exercise of the extension option, each party shall make a separate determination of the Option Rent, as the case may be, within ten (10) business days after the Outside Agreement Date, and such determinations shall be submitted to arbitration in accordance with Sections 2.2.3.1 through 2.2.3.8, below. If Tenant fails to object to Landlord’s determination of the Option Rent within the time period set forth herein, then Tenant shall be deemed to have rejected Landlord’s determination of Option Rent and the matter shall be submitted to arbitration in accordance with the terms hereof.

2.2.3.1 Landlord and Tenant shall each appoint one arbitrator who shall be a MAI appraiser, a real estate broker, or real estate attorney, who shall have been active over the five (5) year period ending on the date of such appointment in the appraisal of Comparable Buildings. The determination of the arbitrators shall be limited solely to the issue of whether Landlord’s or Tenant’s submitted Option Rent is the closest to the actual Option Rent, taking into account the requirements of Section 2.2.2 of this Lease, as determined by the arbitrators.

[Senti Biosciences, Inc.]

Each such arbitrator shall be appointed within fifteen (15) days after the Outside Agreement Date. Landlord and Tenant may consult with their selected arbitrators prior to appointment and may select an arbitrator who is favorable to their respective positions. The arbitrators so selected by Landlord and Tenant shall be deemed “Advocate Arbitrators.”

2.2.3.2 The two (2) Advocate Arbitrators so appointed shall be specifically required pursuant to an engagement letter within ten (10) business days of the date of the appointment of the last appointed Advocate Arbitrator to agree upon and appoint a third arbitrator (“Neutral Arbitrator”) who shall be qualified under the same criteria set forth hereinabove for qualification of the two Advocate Arbitrators, except that neither the Landlord or Tenant or either parties’ Advocate Arbitrator may, directly or indirectly, consult with the Neutral Arbitrator prior or subsequent to his or her appointment. The Neutral Arbitrator shall be retained via an engagement letter jointly prepared by Landlord’s counsel and Tenant’s counsel. The Neutral Arbitrator cannot be someone who has represented Landlord and/or Tenant during the five (5) year period prior to such appointment.

2.2.3.3 The three arbitrators shall, within thirty (30) days of the appointment of the Neutral Arbitrator, reach a decision as to whether the parties shall use Landlord’s or Tenant’s submitted Option Rent, and shall notify Landlord and Tenant thereof.

2.2.3.4 The decision of the majority of the three arbitrators shall be binding upon Landlord and Tenant.

2.2.3.5 If either Landlord or Tenant fails to appoint an Advocate Arbitrator within fifteen (15) days after the Outside Agreement Date, then either party may petition the presiding judge of the Superior Court of San Mateo County to appoint such Advocate Arbitrator subject to the criteria in Section 2.2.3.1 of this Lease, or if he or she refuses to act, either party may petition any judge having jurisdiction over the parties to appoint such Advocate Arbitrator.

2.2.3.6 If the two (2) Advocate Arbitrators fail to agree upon and appoint the Neutral Arbitrator within ten (10) business days after the appointment of the last appointed Advocate Arbitrator, then either party may petition the presiding judge of the Superior Court of San Mateo County to appoint the Neutral Arbitrator, subject to criteria in Section 2.2.3.1 of this Lease, or if he or she refuses to act, either party may petition any judge having jurisdiction over the parties to appoint such arbitrator.

2.2.3.7 The cost of the arbitration shall be paid by Landlord and Tenant equally, except for costs related to the failure of either party to act within the time periods set forth above, which costs shall be borne solely by the non-acting party.

2.2.3.8 In the event that the Option Rent shall not have been determined pursuant to the terms hereof prior to the commencement of the Option Term, Tenant shall be required to pay as Option Rent an amount equal to 103% of the Base Rent payable by Tenant as of the expiration of the initial Lease Term, and upon the final determination of the Option Rent, the payments made by Tenant shall be reconciled with the actual amounts of Option Rent due, and the appropriate party shall make any corresponding payment to the other party.

3. BASE RENT Tenant shall pay, without prior notice or demand, to Landlord or Landlord’s agent at the management office of the Project, or, at Landlord’s option, at such other place as Landlord may from time to time designate in writing, by a check or wire or ETF transfer for currency which, at the time of payment, is legal tender for private or public debts in the United States of America, base rent (“Base Rent”) as set forth in Section 4 of the Summary, payable in equal monthly installments as set forth in Section 4 of the Summary in advance on or before the first day of each and every calendar month during the Lease Term, without any setoff or deduction whatsoever (except for any abatement as permitted under the express terms of this Lease). The Base Rent for the first full month of the Lease Term shall be paid at the time of Tenant’s execution of this Lease. If any Rent payment date (including the Lease Commencement Date) falls on a day of the month other than the first day of such month or if any payment of Rent is for a period which is shorter than one month, the Rent for any fractional month shall accrue on a daily basis for the period from the date such payment is due to the end of such calendar month or to the end of the Lease Term at a rate per day which is equal to 1/365 of the applicable annual Rent. All other payments or adjustments required to be made under the terms of this Lease that require proration on a time basis shall be prorated on the same basis.

4.2.5.3 Any reasonable costs and expenses (including, without limitation, reasonable attorneys’ and consultants’ fees) incurred in attempting to protest, reduce or minimize Tax Expenses shall be included in Tax Expenses in the Expense Year such expenses are incurred. Tax refunds shall be credited against Tax Expenses and refunded to Tenant regardless of when received, based on the Expense Year to which the refund is applicable, provided that in no event shall the amount to be refunded to Tenant for any such Expense Year exceed the total amount paid by Tenant as Additional Rent under this Article 4 for such Expense Year. If Tax Expenses for any period during the Lease Term or any extension thereof are increased after payment thereof for any reason, including, without limitation, error or reassessment by applicable governmental or municipal authorities, Tenant shall pay Landlord upon demand Tenant’s Share of any such increased Tax Expenses.

4.2.6 “Tenant’s Share” shall mean the percentage set forth in Section 6 of the Summary.

4.3 Allocation of Direct Expenses. The parties acknowledge that the Building is a part of a multi-building project and that the costs and expenses incurred in connection with the Project (i.e., the Direct Expenses) should be shared between the Building and the other buildings in the Project. Accordingly, as set forth in Section 4.2 above, Direct Expenses (which consist of Operating Expenses and Tax Expenses) are determined annually for the Project as a whole, and a portion of the Direct Expenses, which portion shall be determined by Landlord on an equitable basis, shall be allocated to the Building (as opposed to other buildings in the Project) and only on the basis of the portion of any calendar year during which any portion of the Lease Term falls. Such portion of Direct Expenses allocated to the Building shall include all Direct Expenses attributable solely to the Building and an equitable portion of the Direct Expenses attributable to the Project as a whole, and shall not include Direct Expenses attributable solely to other buildings in the Project.

4.4 Calculation and Payment of Additional Rent. Commencing on the Lease Commencement Date, Tenant shall pay to Landlord, in the manner set forth in Section 4.4.1, below, and as Additional Rent, Tenant’s Share of Direct Expenses for each Expense Year.

4.4.1 Statement of Actual Direct Expenses and Payment by Tenant. Landlord shall give to Tenant within five (5) months following the end of each Expense Year, a statement (the “Statement”) which shall state the Direct Expenses incurred or accrued for such preceding Expense Year, and which shall indicate the amount of Tenant’s Share of Direct Expenses. Upon receipt of the Statement for each Expense Year commencing or ending during the Lease Term, Tenant shall pay, with its next installment of Base Rent due that is at least thirty (30) days thereafter, the full amount of Tenant’s Share of Direct Expenses for such Expense Year, less the amounts, if any, paid during such Expense Year as “Estimated Direct Expenses,” as that term is defined in Section 4.4.2, below, and if Tenant paid more as Estimated Direct Expenses than the actual Tenant’s Share of Direct Expenses, Tenant shall receive a credit in the amount of Tenant’s overpayment against Rent next due under this Lease. The failure of Landlord to timely furnish the Statement for any Expense Year shall not prejudice Landlord or Tenant from enforcing its rights under this Article 4. Even though the Lease Term has expired and Tenant has vacated the Premises, when the final determination is made of Tenant’s Share of Direct Expenses for the Expense Year in which this Lease terminates, if Tenant’s Share of Direct Expenses is greater than the amount of Estimated Direct Expenses previously paid by Tenant to Landlord, Tenant shall pay to Landlord such amount within thirty (30) days, and if Tenant paid more as Estimated Direct Expenses than the actual Tenant’s Share of Direct Expenses, Landlord shall, within thirty (30) days, deliver a check payable to Tenant in the amount of the overpayment. The provisions of this Section 4.4.1 shall survive the expiration or earlier termination of the Lease Term. Notwithstanding the immediately preceding sentence, Tenant shall not be responsible for Tenant’s Share of any Direct Expenses attributable to any Expense Year which are first billed to Tenant more than two (2) calendar years after the earlier of the expiration of the applicable Expense Year or the Lease Expiration Date, provided that in any event Tenant shall be responsible for Tenant’s Share of Direct Expenses levied by any governmental authority or by any public utility companies at any time following the Lease Expiration Date which are attributable to any Expense Year (provided that Landlord delivers Tenant a bill for such amounts within two (2) years following Landlord’s receipt of the bill therefor).

Britannia Biotech Gateway Business Park

[Britannia Gateway Business Park]

[Senti Biosciences, Inc.]

4.4.2 Statement of Estimated Direct Expenses. In addition, Landlord shall give Tenant a yearly expense estimate statement (the “Estimate Statement”) which shall set forth Landlord’s reasonable estimate (the “Estimate”) of what the total amount of Direct Expenses for the then-current Expense Year shall be and the estimated Tenant’s Share of Direct Expenses (the “Estimated Direct Expenses”). The failure of Landlord to timely furnish the Estimate Statement for any Expense Year shall not preclude Landlord from enforcing its rights to collect any Estimated Direct Expenses under this Article 4, nor shall Landlord be prohibited from revising any Estimate Statement or Estimated Direct Expenses theretofore delivered to the extent necessary; provided that Landlord may not revise the Estimate Statement more than once in any Expense Year. Thereafter, Tenant shall pay, with its next installment of Base Rent due that is at least thirty (30) days thereafter, a fraction of the Estimated Direct Expenses for the then-current Expense Year (reduced by any amounts paid pursuant to the second last sentence of this Section 4.4.2). Such fraction shall have as its numerator the number of months which have elapsed in such current Expense Year, including the month of such payment, and twelve (12) as its denominator. Until a new Estimate Statement is furnished (which Landlord shall have the right to deliver to Tenant at any time), Tenant shall pay monthly, with the monthly Base Rent installments, an amount equal to one-twelfth (1/12) of the total Estimated Direct Expenses set forth in the previous Estimate Statement delivered by Landlord to Tenant. Throughout the Lease Term Landlord shall maintain books and records with respect to Direct Expenses in accordance with sound real estate management and accounting practices, consistently applied.

4.5 Taxes and Other Charges for Which Tenant Is Directly Responsible. Tenant shall be liable for and shall pay before delinquency, taxes levied against Tenant’s equipment, furniture, fixtures and any other personal property located in or about the Premises. If any such taxes on Tenant’s equipment, furniture, fixtures and any other personal property are levied against Landlord or Landlord’s property or if the assessed value of Landlord’s property is increased by the inclusion therein of a value placed upon such equipment, furniture, fixtures or any other personal property and if Landlord pays the taxes based upon such increased assessment, which Landlord shall have the right to do regardless of the validity thereof but only under proper protest if requested by Tenant, Tenant shall upon demand repay to Landlord the taxes so levied against Landlord or the proportion of such taxes resulting from such increase in the assessment, as the case may be.

4.6 Landlord’s Books and Records. Within one hundred twenty (120) days after receipt by Tenant of a Statement, if Tenant disputes the amount of Additional Rent set forth in the Statement, a member of Tenant’s finance department, or an independent certified public accountant (which accountant is a member of a nationally recognized accounting firm and is not working on a contingency fee basis) (“Tenant’s Accountant”), designated and paid for by Tenant, may, after reasonable notice to Landlord and at reasonable times, inspect Landlord’s records with respect to the Statement at Landlord’s offices, provided that there is no existing Event of Default and Tenant has paid all amounts required to be paid under the applicable Estimate Statement and Statement, as the case may be. In connection with such inspection, Tenant and Tenant’s agents must agree in advance to follow Landlord’s reasonable rules and procedures regarding inspections of Landlord’s records, and shall execute a commercially reasonable confidentiality agreement regarding such inspection. Tenant’s failure to dispute the amount of Additional Rent set forth in any Statement within one hundred twenty (120) days of Tenant’s receipt of such Statement shall be deemed to be Tenant’s approval of such Statement and Tenant, thereafter, waives the right or ability to dispute the amounts set forth in such Statement. If after such inspection, Tenant still disputes such Additional Rent, a determination as to the proper amount shall be made, at Tenant’s expense, by an independent certified public accountant (the “Accountant”) selected by Landlord and subject to Tenant’s reasonable approval; provided that if such Accountant determines that Direct Expenses were overstated by more than four percent (4%), then the cost of the Accountant and the cost of such determination shall be paid for by Landlord, and Landlord shall reimburse Tenant for the cost of the Tenant’s Accountant (provided that such cost shall be a reasonable market cost for such services) and the full amount of Tenant’s overpayment of Additional Rent. Tenant hereby acknowledges that Tenant’s sole right to inspect Landlord’s books and records and to contest the amount of Direct Expenses payable by Tenant shall be as set forth in this Section 4.6, and Tenant hereby waives any and all other rights pursuant to Applicable Law to inspect such books and records and/or to contest the amount of Direct Expenses payable by Tenant.

8.2 Manner of Construction. Landlord may impose, as a condition of its consent to any and all Alterations or repairs of the Premises or about the Premises, such requirements as Landlord in its reasonable discretion may deem desirable, including, but not limited to, the requirement that upon Landlord’s request given at the time of its consent, Tenant shall, at Tenant’s expense, remove such Alterations upon the expiration or any early termination of the Lease Term. Tenant shall construct such Alterations and perform such repairs in a good and workmanlike manner, in conformance with any and all applicable federal, state, county or municipal laws, rules and regulations and pursuant to a valid building permit, issued by the city in which the Building is located (or other applicable governmental authority). Tenant shall not use (and upon notice from Landlord shall cease using) contractors, services, workmen, labor, materials or equipment that, in Landlord’s reasonable judgment, would disturb labor harmony with the workforce or trades engaged in performing other work, labor or services in or about the Building or the Common Areas. Upon completion of any Alterations (or repairs), Tenant shall deliver to Landlord final lien waivers from all contractors, subcontractors and materialmen who performed such work. In addition to Tenant’s obligations under Article 9 of this Lease, upon completion of any Alterations, Tenant agrees to cause a Notice of Completion to be recorded in the office of the Recorder of the County of San Mateo in accordance with Section 3093 of the Civil Code of the State of California or any successor statute, and Tenant shall deliver to the Project construction manager a reproducible copy of the “as built” drawings of the Alterations as well as copies of all permits, approvals and other documents issued by any governmental agency in connection with the Alterations.

In addition to the requirements of Article 10 of this Lease, in the event that Tenant makes any Alterations, prior to the commencement of such Alterations, Tenant shall provide Landlord with evidence that Tenant or Tenant’s contractor carries “Builder’s All Risk” insurance (to the extent that the cost of such work shall exceed $50,000) in an amount approved by Landlord covering the construction of such Alterations, and such other insurance as Landlord may reasonably require, it being understood and agreed that all of such Alterations shall be insured by Tenant pursuant to Article 10 of this Lease promptly upon completion thereof. In addition, Tenant’s contractors and subcontractors shall be required to carry (i) Commercial General Liability Insurance in an amount approved by Landlord, with Landlord, and, at Landlord’s option, Landlord’s property manager and project manager, as additional insureds in an amount approved by Landlord, and otherwise in accordance with the requirements of Article 10 of this Lease, and (ii) workers compensation insurance with a waiver of subrogation in favor of Landlord. In connection with Alterations with a cost in excess of $250,000.00, Landlord may, in its reasonable discretion, require Tenant to obtain a lien and completion bond or some alternate form of security satisfactory to Landlord in an amount sufficient to ensure the lien-free completion of such Alterations and naming Landlord as a co-obligee.

8.5 Landlord’s Property. All Alterations, improvements, fixtures, equipment and/or appurtenances which may be installed or placed in or about the Premises (excluding Tenant’s trade fixtures, furniture and equipment), from time to time, shall be at the sole cost of Tenant (except as set forth in the Tenant Work Letter) and all Alterations and improvements, shall be and become the property of Landlord and remain in place at the Premises following the expiration or earlier termination of this Lease. Notwithstanding the foregoing, Landlord may, by written notice to Tenant given at the time it consents to an Alteration, require Tenant, at Tenant’s expense, to remove any Alterations within the Premises and to repair any damage to the Premises and Building caused by such removal. If Tenant fails to complete such removal and/or to repair any damage caused by the removal of any Alterations, Landlord may do so and may charge the reasonable, out-of-pocket cost thereof to Tenant. Tenant hereby protects, defends, indemnifies and holds Landlord harmless from any liability, cost, obligation, expense or claim of lien in any manner relating to the installation, placement, removal or financing of any such Alterations, improvements, fixtures and/or equipment in, on or about the Premises, which obligations of Tenant shall survive the expiration or earlier termination of this Lease, provided with respect to the construction of the initial Tenant Improvements to the Premises, the same shall be governed by the terms of the Tenant Work Letter and not the terms of this Article 8..

9. COVENANT AGAINST LIENS Tenant shall keep the Project and Premises free from any liens or encumbrances arising out of the work performed, materials furnished or obligations incurred by or on behalf of Tenant, and shall protect, defend, indemnify and hold Landlord harmless from and against any third-party claims, liabilities, judgments or costs (including, without limitation, reasonable attorneys’ fees and costs) arising out of same or in connection therewith. Except as to Permitted Alterations, Tenant shall give Landlord notice at least ten (10) business days prior to the commencement of any such work on the Premises (or such additional time as may be necessary under Applicable Laws) to afford Landlord the opportunity of posting and recording appropriate notices of non-responsibility (to the extent applicable pursuant to then Applicable Laws). Tenant shall remove any such lien or encumbrance by bond or otherwise within ten (10) business days after notice by Landlord, and if Tenant shall fail to do so, Landlord may pay the amount necessary to remove such lien or encumbrance, without being responsible for investigating the validity thereof.

10. INSURANCE

10.1 Indemnification and Waiver. Except as provided in Section 10.5 or to the extent due to the negligence, willful misconduct or violation of this Lease by Landlord or the Landlord Parties, Tenant hereby assumes all risk of damage to property or injury to persons in, upon or about the Premises from any cause whatsoever and agrees that Landlord, its partners, subpartners and their respective officers, agents, servants, employees, and independent contractors (collectively, “Landlord Parties”) shall not be liable for, and are hereby released from any responsibility for, any damage either to person or property or resulting from the loss of use thereof, which damage is sustained by Tenant or by other persons claiming through Tenant. Tenant shall indemnify, defend, protect, and hold harmless the Landlord Parties from any and all claims, loss, cost, damage, injury, expense and liability (including without limitation court costs and reasonable attorneys’ fees) incurred in connection with or arising from any cause in, on or about the Premises, any acts, omissions or negligence of Tenant or of any person claiming by, through or under Tenant, or of the contractors, agents, servants, employees, invitees, guests or licensees of Tenant or any such person, in, on or about the Project or any breach of the terms of this Lease, either prior to, during, or after the expiration of the Lease Term, provided that the terms of the foregoing indemnity shall not apply to the negligence or willful misconduct of Landlord or the Landlord Parties, or Landlord’s violation of this Lease. Should Landlord be named as a defendant in any suit brought against Tenant in connection with or arising out of Tenant’s occupancy of the Premises, Tenant shall pay to Landlord its costs and expenses incurred in such suit, including without limitation, its actual professional fees such as reasonable appraisers’, accountants’ and attorneys’ fees. Notwithstanding anything to the contrary in this Lease, Landlord shall not be released or indemnified from, and shall indemnify, defend, protect and hold harmless Tenant from, all losses, damages, liabilities, claims, attorneys’ fees, costs and expenses arising from the gross negligence or willful misconduct of Landlord or its agents, contractors, licensees or invitees, or a violation of Landlord’s obligations or representations under this Lease. Subject to Tenant’s indemnification obligations set forth above and the waiver of subrogation provided below, Landlord shall indemnify, defend, protect, and hold harmless Tenant from any and all loss, cost, damage, expense, and liability (including, without limitation, court costs and reasonable attorneys’ fees) to the extent arising from the gross negligence or willful misconduct of Landlord or the Landlord Parties in, on or about the Project, provided that the terms of the foregoing indemnity shall not apply to the negligence or willful misconduct of Tenant. Notwithstanding anything to the contrary set forth in this Lease, either party’s agreement to indemnify the other party as set forth in this Section 10.1 shall be ineffective to the extent the matters for which such party agreed to indemnify the other party are covered by insurance required to be carried by the non-indemnifying party pursuant to this Lease. Further, Tenant’s agreement to indemnify Landlord and Landlord’s agreement to indemnify Tenant, each pursuant to this Section 10.1 is not intended and shall not relieve any insurance carrier of its obligations under policies required to be carried pursuant to the provisions of this Lease, to the extent such policies cover the matters subject to the parties’ respective indemnification obligations; nor shall they supersede any inconsistent agreement of the parties set forth in any other provision of this Lease. The provisions of this Section 10.1 shall survive the expiration or sooner termination of this Lease with respect to any claims or liability arising in connection with any event occurring prior to such expiration or termination.

10.2 Tenant’s Compliance With Landlord’s Property Insurance. Landlord shall insure the Building, Tenant Improvements and any Alterations during the Lease Term against loss or damage under an “all risk” property insurance policy. Such coverage shall be in such amounts, from such companies, and on such other terms and conditions, as Landlord may from time to time reasonably determine. Additionally, at the option of Landlord, such insurance coverage may include the risks of earthquakes and/or flood damage and additional hazards, a rental loss endorsement and one or more loss payee endorsements in favor of the holders of any mortgages or deeds of trust encumbering the interest of Landlord in the Building or the ground or underlying lessors of the Building, or any portion thereof. The costs of such insurance shall be included in Operating Expenses, subject to the terms of Section 4.2.4. Tenant shall, at Tenant’s expense, comply with all insurance company requirements pertaining to the use of the Premises. If Tenant’s conduct or use of the Premises causes any increase in the premium for such insurance policies then Tenant shall reimburse Landlord for any such increase. Tenant, at Tenant’s expense, shall comply with all rules, orders, regulations or requirements of the American Insurance Association (formerly the National Board of Fire Underwriters) and with any similar body. Notwithstanding anything to the contrary in this Lease, Tenant shall not be required to comply with or cause the Premises to comply with any laws, rules, regulations or insurance requirements requiring the construction of alterations unless such compliance is necessitated solely due to Tenant’s particular use of the Premises.

10.3 Tenant’s Insurance. Tenant shall maintain the following coverages in the following amounts.

10.3.1 Commercial General Liability Insurance on an occurrence form covering the insured against claims of bodily injury, personal injury and property damage (including loss of use thereof) arising out of Tenant’s operations, and contractual liabilities including a contractual coverage, and including products and completed operations coverage, for limits of liability on a per location basis of not less than:


Bodily Injury and Property Damage Liability		$5,000,000 each occurrence $5,000,000 annual aggregate

Personal Injury Liability		$3,000,000 each occurrence $3,000,000 annual aggregate

10.3.2 Property Insurance covering (i) all office furniture, business and trade fixtures, office equipment, free-standing cabinet work, movable partitions, merchandise and all other items of Tenant’s property on the Premises installed by, for, or at the expense of Tenant, and (ii) all other improvements, alterations and additions to the Premises. Such insurance shall be written on an “all risks” of physical loss or damage basis, for the full replacement cost value (subject to reasonable deductible amounts) new without deduction for depreciation of the covered items and in amounts that meet any co-insurance clauses of the policies of insurance and shall include coverage for damage or other loss caused by fire or other peril including, but not limited to, vandalism and malicious mischief, theft, water damage of any type, including sprinkler leakage, bursting or stoppage of pipes, and explosion.

10.3.3 Business Income Interruption for six (6) months plus Extra Expense insurance in such amounts as will reimburse Tenant for actual direct or indirect loss of earnings attributable to the risks outlined in Section 10.3.2 above.

10.3.4 Worker’s Compensation and Employer’s Liability or other similar insurance pursuant to all applicable state and local statutes and regulations. The policy shall include a waiver of subrogation in favor of Landlord, its employees, Lenders and any property manager or partners.

10.4 Form of Policies. The minimum limits of policies of insurance required of Tenant under this Lease shall in no event limit the liability of Tenant under this Lease. Such insurance shall (i) name Landlord, its subsidiaries and affiliates, its property manager (if any) and any other party the Landlord so specifies, as an additional insured or loss payee, as applicable, including Landlord’s managing agent, if any; (ii) be issued by an insurance company having a rating of not less than A:IX in Best’s Insurance Guide or which is otherwise reasonably acceptable to Landlord and licensed to do business in the State of California; (iv) be primary insurance as to all claims thereunder and provide that any insurance carried by Landlord is excess and is non-contributing with any insurance required of Tenant; (v) be in form and content reasonably acceptable to Landlord; and (vi) if available, provide that said insurance shall not be canceled or coverage changed unless thirty (30) days’ prior written notice shall have been given to Landlord and any mortgagee of Landlord (unless such cancellation is the result of non-payment of premiums). Tenant shall deliver said policy or policies or certificates thereof to Landlord on or before the Lease Commencement Date and at least ten (10) days before the expiration dates thereof. In the event Tenant shall fail to procure such insurance, or to deliver such policies or certificate, and such failure is not cured within five (5) business days after Tenant’s receipt of written notice from, then Landlord may, at its option, procure such policies for the account of Tenant, and the out-of-pocket cost thereof shall be paid to Landlord within five (5) business days after delivery to Tenant of bills therefor.

10.5 Subrogation. Landlord and Tenant hereby agree to look solely to, and seek recovery only from, their respective insurance carriers in the event of a property or business interruption loss to the extent that such coverage is agreed to be provided hereunder. The parties each hereby waive all rights and claims against each other for such losses, and waive all rights of subrogation of their respective insurers, provided such waiver of subrogation shall not affect the right to the insured to recover thereunder. The parties agree that their respective insurance policies do now, or shall, contain the waiver of subrogation.

10.6 Additional Insurance Obligations. Tenant shall carry and maintain during the entire Lease Term, at Tenant’s sole cost and expense, increased amounts of the insurance required to be carried by Tenant pursuant to this Article 10 and such other reasonable types of insurance coverage and in such reasonable amounts covering the Premises and Tenant’s operations therein, as may be reasonably requested by Landlord or Landlord’s lender, but in no event in excess of the amounts and types of insurance then being required by landlords of buildings comparable to and in the vicinity of the Building. Landlord may change the amounts and/or types of insurance required to be carried by Tenant in accordance with the preceding sentence only once in any five (5) year period.

11. DAMAGE AND DESTRUCTION

11.1 Repair of Damage to Premises by Landlord. Tenant shall promptly notify Landlord of any damage to the Premises resulting from fire or any other casualty. If the Premises or any Common Areas serving or providing access to the Premises shall be damaged by fire or other casualty, Landlord shall promptly and diligently, subject to reasonable delays for insurance adjustment or other matters beyond Landlord’s reasonable control, and subject to all other terms of this Article 11, restore the Premises and such Common Areas. Such restoration shall be to substantially the same condition of the Premises and the Common Areas prior to the casualty, except for modifications required by zoning and building codes and other laws or any other modifications to the Common Areas deemed desirable by Landlord, which are consistent with the character of the Project, provided that access to the Premises shall not be materially impaired. Landlord shall not be liable for any inconvenience or annoyance to Tenant or its visitors, or injury to Tenant’s business resulting in any way from such damage or the repair thereof; provided however, that if such fire or other casualty shall have damaged the Premises or Common Areas necessary to Tenant’s occupancy, and the damaged portions of the Premises are not occupied by Tenant as a result thereof, then during the time and to the extent the Premises are unfit for occupancy, the Rent shall be abated in proportion to the ratio that the amount of rentable square feet of the Premises which is unfit for occupancy for the purposes permitted under this Lease bears to the total rentable square feet of the Premises.

11.2 Landlord’s Option to Repair. Notwithstanding the terms of Section 11.1 of this Lease, Landlord may elect not to rebuild and/or restore the Premises, Building and/or Project, and instead terminate this Lease, by notifying Tenant in writing of such termination within ninety (90) days after the date of discovery of the damage, such notice to include a termination date giving Tenant sixty (60) days to vacate the Premises, but Landlord may so elect only if the Building shall be damaged by fire or other casualty or cause, and one or more of the following conditions is present: (i) in Landlord’s reasonable judgment, repairs cannot reasonably be completed within one (1) year after the date of discovery of the damage (when such repairs are made without the payment of overtime or other premiums); (ii) the damage is due to a risk that Landlord is not required to insure under this Lease, and the cost of restoration exceed five percent (5%) of the replacement cost of the Building (unless Tenant agrees to pay any uninsured amount in excess of such five percent (5%)); or (iii) the damage occurs during the last twelve (12) months of the Lease Term and will take more than sixty (60) days to restore; provided, however, that if Landlord does not elect to terminate this Lease pursuant to Landlord’s termination right as provided above, and the repairs cannot, in the reasonable opinion of Landlord, be completed within seven (7) months after the date of discovery of the damage (or are not in fact completed within eight (8) months after the date of discovery of the damage), Tenant may elect, no earlier than sixty (60) days after the date of the damage and not later than ninety (90) days after the date of such damage, or within thirty (30) days after such repairs are not timely completed, to terminate this Lease by written notice to Landlord effective as of the date specified in the notice, which date shall not be less than thirty (30) days nor more than sixty (60) days after the date such notice is given by Tenant.

11.3 Waiver of Statutory Provisions. The provisions of this Lease, including this Article 11, constitute an express agreement between Landlord and Tenant with respect to any and all damage to, or destruction of, all or any part of the Premises, the Building or the Project, and any statute or regulation of the State of California, including, without limitation, Sections 1932(2) and 1933(4) of the California Civil Code, with respect to any rights or obligations concerning damage or destruction in the absence of an express agreement between the parties, and any other statute or regulation, now or hereafter in effect, shall have no application to this Lease or any damage or destruction to all or any part of the Premises, the Building or the Project.

12. NONWAIVER No provision of this Lease shall be deemed waived by either party hereto unless expressly waived in a writing signed by such party. The waiver by either party hereto of any breach of any term, covenant or condition herein contained shall not be deemed to be a waiver of any subsequent breach of same or any other term, covenant or condition herein contained. The subsequent acceptance of Rent hereunder by Landlord shall not be deemed to be a waiver of any preceding breach by Tenant of any term, covenant or condition of this Lease, other than the failure of Tenant to pay the particular Rent so accepted, regardless of Landlord’s knowledge of such preceding breach at the time of acceptance of such Rent. No acceptance of a lesser amount than the Rent herein stipulated shall be deemed a waiver of Landlord’s right to receive the full amount due, nor shall any endorsement or statement on any check or payment or any letter accompanying such check or payment be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the full amount due. No receipt of monies by Landlord from Tenant after the termination of this Lease shall in any way alter the length of the Lease Term or of Tenant’s right of possession hereunder, or after the giving of any notice shall reinstate, continue or extend the Lease Term or affect any notice given Tenant prior to the receipt of such monies, it being agreed that after the service of notice or the commencement of a suit, or after final judgment for possession of the Premises, Landlord may receive and collect any Rent due, and the payment of said Rent shall not waive or affect said notice, suit or judgment.

13. CONDEMNATION If the whole or any material part of the Premises, Building or Project shall be taken by power of eminent domain or condemned by any competent authority for any public or quasi-public use or purpose, or if any adjacent property or street shall be so taken or condemned, or reconfigured or vacated by such authority in such manner as to require the use, reconstruction or remodeling of any material part of the Premises, Building or Project, or if Landlord shall grant a deed or other instrument in lieu of such taking by eminent domain or condemnation, Landlord shall have the option to terminate this Lease effective as of the date possession is required to be surrendered to the authority. If more than twenty percent (20%) of the rentable square footage of the Premises is taken, or if access to the Premises is substantially impaired, in each case for a period in excess of one hundred eighty (180) days, Tenant shall have the option to terminate this Lease effective as of the date possession is required to be surrendered to the authority. Tenant shall not because of such taking assert any claim against Landlord or the authority for any compensation because of such taking and Landlord shall be entitled to the entire award or payment in connection therewith, except that Tenant shall have the right to file any separate claim available to Tenant for any taking of Tenant’s personal property and fixtures belonging to Tenant and removable by Tenant upon expiration of the Lease Term pursuant to the terms of this Lease, for moving expenses, for the unamortized value of any improvements paid for by Tenant and for the Lease “bonus value”, so long as such claims are payable separately to Tenant. All Rent shall be apportioned as of the date of such termination. If any part of the Premises shall be taken, and this Lease shall not be so terminated, the Rent shall be proportionately abated. Tenant hereby waives any and all rights it might otherwise have pursuant to Section 1265.130 of The California Code of Civil Procedure. Notwithstanding anything to the contrary contained in this Article 13, in the event of a temporary taking of all or any portion of the Premises for a period of one hundred and eighty (180) days or less, then this Lease shall not terminate but the Base Rent and the Additional Rent shall be abated for the period of such taking in proportion to the ratio that the amount of rentable square feet of the Premises taken bears to the total rentable square feet of the Premises. Landlord shall be entitled to receive the entire award made in connection with any such temporary taking.

14. ASSIGNMENT AND SUBLETTING

14.1 Transfers. Except as specifically permitted in Section 14.8, below, Tenant shall not, without the prior written consent of Landlord, assign, mortgage, pledge, hypothecate, encumber, or permit any lien to attach to, or otherwise transfer, this Lease or any interest hereunder, permit any assignment, or other transfer of this Lease or any interest hereunder by operation of law, sublet the Premises or any part thereof, or enter into any license or concession agreements or otherwise permit the occupancy or use of the Premises or any part thereof by any persons other than Tenant and its employees, agents and contractors (all of the foregoing are hereinafter sometimes referred to collectively as “Transfers” and any person to whom any Transfer is made or sought to be made is hereinafter sometimes referred to as a “Transferee”). If Tenant desires Landlord’s consent to any Transfer (except for a Permitted Transfer), Tenant shall notify Landlord in writing, which notice (the “Transfer Notice”) shall include (i) the proposed effective date of the Transfer, which shall not be less than twenty (20) days nor more than one hundred eighty (180) days after the date of delivery of the Transfer Notice, (ii) a description of the portion of the Premises to be transferred (the “Subject Space”), (iii) all of the material terms of the proposed Transfer and the consideration therefor, including calculation of the “Transfer Premium”, as that term is defined in Section 14.3 below, in connection with such Transfer, the name and address of the proposed Transferee, and a copy of all existing executed and/or proposed documentation pertaining to the proposed Transfer, and (iv) current financial statements of the proposed Transferee certified by an officer, partner or owner thereof, and any other information reasonably required by Landlord which will enable Landlord to determine the financial responsibility, character, and reputation of the proposed Transferee, nature of such Transferee’s business and proposed use of the Subject Space. Except as specifically permitted in Section 14.8, below, any Transfer made without Landlord’s prior written consent shall, at Landlord’s option, be null, void and of no effect, and shall, at Landlord’s option, constitute a default by Tenant under this Lease. Whether or not Landlord consents to any proposed Transfer, Tenant shall pay Landlord’s reasonable review and processing fees, as well as any reasonable professional fees (including, without limitation, attorneys’, accountants’, architects’, engineers’ and consultants’ fees) incurred by Landlord (not to exceed $3,500 in the aggregate for any particular Transfer), within thirty (30) days after written request by Landlord.

14.2 Landlord’s Consent. Landlord shall not unreasonably withhold, condition or delay its consent to any proposed Transfer of the Subject Space to the Transferee on the terms specified in the Transfer Notice. Landlord shall approve or disapprove of any proposed Transfer within fifteen (15) business days after receipt of a complete Transfer Notice. If Landlord fails to respond within such fifteen (15) business day period, then Tenant may send Landlord a reminder notice setting forth such failure containing the following sentence at the top of such notice in bold, capitalized font at least twelve (12) points in size: “LANDLORD’S FAILURE TO RESPOND TO THIS NOTICE WITHIN FIVE (5) BUSINESS DAYS SHALL RESULT IN LANDLORD’S DEEMED APPROVAL OF TENANT’S REQUEST FOR TRANSFER” (the “Transfer Reminder Notice”). Any such Transfer Reminder Notice shall include a complete copy of Tenant’s Transfer Notice. If Landlord fails to respond within five (5) business days after receipt of a Transfer Reminder Notice, then Tenant’s Transfer for which Tenant requested Landlord’s approval shall be deemed approved by Landlord. Without limitation as to other reasonable grounds for withholding consent, the parties hereby agree that it shall be reasonable under this Lease and under any Applicable Law for Landlord to withhold consent to any proposed Transfer where one or more of the following apply:

14.2.1 The Transferee is of a character or reputation or engaged in a business which is not consistent with the quality of the Building or the Project;

14.2.2 The Transferee is either a governmental agency or instrumentality thereof;

14.2.3 The Transferee is not a party of reasonable financial worth and/or financial stability in light of the responsibilities to be undertaken in connection with the Transfer on the date consent is requested; or

14.2.4 The proposed Transfer would cause a violation of another lease for space in the Project, or would give an occupant of the Project a right to cancel its lease.

If Landlord consents to any Transfer pursuant to the terms of this Section 14.2 (and does not exercise any recapture rights Landlord may have under Section 14.4 of this Lease), Tenant may within six (6) months after Landlord’s consent, but not later than the expiration of said six-month period, enter into such Transfer of the Premises or portion thereof, upon substantially the same terms and conditions as are set forth in the Transfer Notice furnished by Tenant to Landlord pursuant to Section 14.1 of this Lease, provided that if there are any changes in the terms and conditions from those specified in the Transfer Notice such that Landlord would initially have been entitled to refuse its consent to such Transfer under this Section 14.2, Tenant shall again submit the Transfer to Landlord for its approval and other action under this Article 14 (including Landlord’s right of recapture, if any, under Section 14.4 of this Lease). Notwithstanding anything to the contrary in this Lease, if Tenant or any proposed Transferee claims that Landlord has unreasonably withheld or delayed its consent under Section 14.2 or otherwise has breached or acted unreasonably under this Article 14, their sole remedies shall be a suit for contract damages (other than damages for injury to, or interference with, Tenant’s business including, without limitation, loss of profits, however occurring) or declaratory judgment and an injunction for the relief sought, and Tenant hereby waives all other remedies, including, without limitation, any right at law or equity to terminate this Lease, on its own behalf and, to the extent permitted under all Applicable Laws, on behalf of the proposed Transferee.

[Senti Biosciences, Inc.]

14.3 Transfer Premium. If Landlord consents to a Transfer, as a condition thereto which the parties hereby agree is reasonable, Tenant shall pay to Landlord fifty percent (50%) of any “Transfer Premium,” as that term is defined in this Section 14.3, received by Tenant from such Transferee. “Transfer Premium” shall mean all rent, additional rent or other consideration payable by such Transferee in connection with the Transfer in excess of the Rent and Additional Rent payable by Tenant under this Lease during the term of the Transfer on a per rentable square foot basis if less than all of the Premises is transferred, and after deduction of (i) any costs of improvements made to the Subject Space in connection with such Transfer (including architectural fees), (ii) free rent, rent abatement or tenant improvement allowance provided in connection with such Transfer, (iii) marketing expenses and brokerage commissions paid in connection with such Transfer, (iv) reasonable legal fees incurred in connection with such Transfer, and (v) fees paid to Landlord in connection with Tenant’s request for consent. “Transfer Premium” shall also include, but not be limited to, key money, bonus money or other cash consideration paid by Transferee to Tenant in connection with such Transfer, and any payment in excess of fair market value for services rendered by Tenant to Transferee or for assets, fixtures, inventory, equipment, or furniture transferred by Tenant to Transferee in connection with such Transfer. The determination of the amount of Landlord’s applicable share of the Transfer Premium shall be made on a monthly basis as rent or other consideration is received by Tenant under the Transfer.

14.4 Landlord’s Option as to Subject Space. Notwithstanding anything to the contrary contained in this Article 14, in the event Tenant contemplates a Transfer other than to a Permitted Transferee that, together with all prior Transfers then remaining in effect, would cause fifty percent (50%) or more of the Premises to be Transferred for more than fifty percent (50%) of the then remaining Lease Term (taking into account any extension of the Lease Term which has irrevocably exercised by Tenant), Tenant shall give Landlord notice (the “Intention to Transfer Notice”) of such contemplated Transfer (whether or not the contemplated Transferee or the terms of such contemplated Transfer have been determined). The Intention to Transfer Notice shall specify the portion of and amount of rentable square feet of the Premises which Tenant intends to Transfer (the “Contemplated Transfer Space”), the contemplated date of commencement of the Contemplated Transfer (the “Contemplated Effective Date”), and the contemplated length of the term of such contemplated Transfer, and shall specify that such Intention to Transfer Notice is delivered to Landlord pursuant to this Section 14.4 in order to allow Landlord to elect to recapture the Contemplated Transfer Space. Thereafter, Landlord shall have the option, by giving written notice to Tenant within twenty (20) days after receipt of any Intention to Transfer Notice, to recapture the Contemplated Transfer Space. Such recapture shall cancel and terminate this Lease with respect to such Contemplated Transfer Space as of the Contemplated Effective Date and this Lease shall remain in effect with respect to the balance of the Premises not so recaptured. In the event of a recapture by Landlord, if this Lease shall be canceled with respect to less than the entire Premises, the Rent reserved herein shall be prorated on the basis of the number of rentable square feet retained by Tenant in proportion to the number of rentable square feet contained in the Premises, and this Lease as so amended shall continue thereafter in full force and effect, and upon request of either party, the parties shall execute written confirmation of the same. If Landlord declines, or fails to elect in a timely manner, to recapture such Contemplated Transfer Space under this Section 14.4, then, subject to the other terms of this Article 14, for a period of nine (9) months (the “Nine Month Period”) commencing on the last day of such twenty (20) day period, Landlord shall not have any right to recapture the Contemplated Transfer Space with respect to any Transfer made during the Nine Month Period, provided that any such Transfer is substantially on the terms set forth in the Intention to Transfer Notice, and provided further that any such Transfer shall be subject to the remaining terms of this Article 14. If such a Transfer is not so consummated within the Nine Month Period (or if a Transfer is so consummated, then upon the expiration of the term of any Transfer of such Contemplated Transfer Space consummated within such Nine Month Period), Tenant shall again be required to submit a new Intention to Transfer Notice to Landlord with respect any contemplated Transfer, as provided above in this Section 14.4. The recapture right set forth in this Section 14.4 shall not apply in connection with any transfer of this Lease to a Permitted Transferee.

14.5 Effect of Transfer. If Landlord consents to a Transfer, (i) the terms and conditions of this Lease shall in no way be deemed to have been waived or modified, (ii) such consent shall not be deemed consent to any further Transfer by either Tenant or a Transferee, (iii) Tenant shall deliver to Landlord, promptly after execution, an original executed copy of all documentation pertaining to the Transfer in form reasonably acceptable to Landlord, (iv) Tenant shall furnish upon Landlord’s request a complete statement, certified by an independent certified public accountant, or Tenant’s chief financial officer, setting forth in detail the computation of any Transfer Premium Tenant has derived and shall derive from such Transfer, and (v) no Transfer relating to this Lease or agreement entered into with respect thereto, whether with or without Landlord’s consent, shall relieve Tenant or any guarantor of the Lease from any liability under this Lease, including, without limitation, in connection with the Subject Space. Landlord or its authorized representatives shall have the right at all reasonable times to audit the books, records and papers of Tenant relating to any Transfer, and shall have the right to make copies thereof. If the Transfer Premium respecting any Transfer shall be found understated, Tenant shall, within thirty (30) days after demand, pay the deficiency, and if understated by more than four percent (4%), Tenant shall pay Landlord’s reasonable costs of such audit.

14.6 Additional Transfers. For purposes of this Lease, the term “Transfer” shall also include if Tenant is a partnership, the withdrawal or change, voluntary, involuntary or by operation of law, of fifty percent (50%) or more of the partners, or transfer of fifty percent (50%) or more of partnership interests, within a twelve (12)-month period, or the dissolution of the partnership without immediate reconstitution thereof. The terms of this Section 14.6 are subject to the terms of Section 14.8 below.

14.7 Occurrence of Default. Any Transfer hereunder shall be subordinate and subject to the provisions of this Lease, and if this Lease shall be terminated during the term of any Transfer, Landlord shall have the right to: (i) treat such Transfer as cancelled and repossess the Subject Space by any lawful means, or (ii) require that such Transferee attorn to and recognize Landlord as its landlord under any such Transfer. If Tenant shall be in monetary or material non-monetary default under this Lease beyond any applicable notice and cure periods, Landlord is hereby irrevocably authorized to direct any Transferee to make all payments under or in connection with the Transfer directly to Landlord (which Landlord shall apply towards Tenant’s obligations under this Lease) until such default is cured. Such Transferee shall rely on any representation by Landlord that Tenant is in default hereunder, without any need for confirmation thereof by Tenant. Upon any assignment, the assignee shall assume in writing all obligations and covenants of Tenant thereafter to be performed or observed under this Lease. No collection or acceptance of rent by Landlord from any Transferee shall be deemed a waiver of any provision of this Article 14 or the approval of any Transferee or a release of Tenant from any obligation under this Lease, whether theretofore or thereafter accruing. In no event shall Landlord’s enforcement of any provision of this Lease against any Transferee be deemed a waiver of Landlord’s right to enforce any term of this Lease against Tenant or any other person. If Tenant’s obligations hereunder have been guaranteed, Landlord’s consent to any Transfer shall not be effective unless the guarantor also consents to such Transfer.

14.8 Non-Transfers. Notwithstanding anything to the contrary contained in this Article 14, (i) an assignment of the Lease or subletting of all or a portion of the Premises to an affiliate of Tenant (an entity which is controlled by, controls, or is under common control with, Tenant), (ii) an assignment Lease or subletting or all or a portion of the of the Premises to an entity which acquires all or substantially all of the assets or interests (partnership, stock or other) of Tenant, (iii) an assignment of the Lease or a subletting or all of a portion of the Premises to an entity which is the resulting entity of a merger or consolidation of Tenant with another entity, or (iv) a change of Control or the sale of corporate shares of capital stock in Tenant (collectively, a “Permitted Transferee”), shall not be deemed a Transfer under this Article 14 (and for the avoidance of doubt, Sections 14.2, 14.3 and 14.4 shall not apply), provided that (A) Tenant notifies Landlord of any such assignment or sublease and promptly supplies Landlord with any documents or information requested by Landlord regarding such assignment or sublease or such affiliate, (B) such assignment or sublease is not a subterfuge by Tenant to avoid its obligations under this Lease, (C) such Permitted Transferee shall be of a character and reputation consistent with the quality of the Building, and (D) such Permitted Transferee described in subpart (ii) or (iii) above shall have a tangible net worth (not including goodwill as an asset) computed in accordance with generally accepted accounting principles (“Net Worth”) at least equal to the Net Worth of Tenant on the day immediately preceding the effective date of such assignment or sublease. An assignee of Tenant’s entire interest that is also a Permitted Transferee may also be known as a “Permitted Assignee”. “Control,” as used in this Section 14.8, shall mean the ownership, directly or indirectly, of at least fifty-one percent (51%) of the voting securities of, or possession of the right to vote, in the ordinary direction of its affairs, of at least fifty-one percent (51%) of the voting interest in, any person or entity. No such permitted assignment or subletting shall serve to release Tenant from any of its obligations under this Lease.

15. SURRENDER OF PREMISES; OWNERSHIP AND REMOVAL OF TRADE FIXTURES

15.1 Surrender of Premises. No act or thing done by Landlord or any agent or employee of Landlord during the Lease Term shall be deemed to constitute an acceptance by Landlord of a surrender of the Premises unless such intent is specifically acknowledged in writing by Landlord. The delivery of keys to the Premises to Landlord or any agent or employee of Landlord shall not constitute a surrender of the Premises or effect a termination of this Lease, whether or not the keys are thereafter retained by Landlord, and notwithstanding such delivery Tenant shall be entitled to the return of such keys at any reasonable time upon request until this Lease shall have been properly terminated. The voluntary or other surrender of this Lease by Tenant, whether accepted by Landlord or not, or a mutual termination hereof, shall not work a merger, and at the option of Landlord shall operate as an assignment to Landlord of all subleases or subtenancies affecting the Premises or terminate any or all such sublessees or subtenancies.

15.2 Removal of Tenant Property by Tenant. Upon the expiration of the Lease Term, or upon any earlier termination of this Lease, Tenant shall, subject to the provisions of this Article 15, quit and surrender possession of the Premises to Landlord in the same order and condition as when Tenant took possession and as thereafter improved by Landlord and/or Tenant, reasonable wear and tear, damage caused by casualty, repairs required as a result of condemnation, and repairs that are specifically made the responsibility of Landlord hereunder excepted. Upon such expiration or termination, Tenant shall, without expense to Landlord, remove or cause to be removed from the Premises all debris and rubbish, and such items of furniture, equipment, free-standing cabinet work, movable partitions and other articles of personal property owned by Tenant or installed or placed by Tenant at its expense in the Premises, and such similar articles of any other persons claiming under Tenant, as Landlord may, in its sole discretion, require to be removed, and Tenant shall repair at its own expense all damage to the Premises and Building resulting from such removal. Notwithstanding anything herein to the contrary, Tenant shall be permitted to remove its non-affixed furniture, trade fixtures, equipment, and any other personal property from the Premises.

15.3 Environmental Assessment. In connection with its surrender of the Premises, Tenant shall submit to Landlord, at least fifteen (15) days prior to the expiration date of this Lease (or in the event of an earlier termination of this Lease, as soon as reasonably possible following such termination), an environmental Assessment of the Premises by a competent and experienced environmental engineer or engineering firm reasonably satisfactory to Landlord (pursuant to a contract approved by Landlord and providing that Landlord can rely on the Environmental Assessment). If such Environmental Assessment reveals that remediation or Clean-up is required under any Environmental Laws that Tenant is responsible for under this Lease, Tenant shall submit a remediation plan prepared by a recognized environmental consultant and shall be responsible for all costs of remediation and Clean-up, as more particularly provided in Section 5.3, above.

15.4 Condition of the Building and Premises Upon Surrender. In addition to the above requirements of this Article 15, upon the expiration of the Lease Term, or upon any earlier termination of this Lease, Tenant shall, surrender the Premises and Building and with Tenant having complied with all of Tenant’s obligations under this Lease, including those relating to improvement, repair, maintenance, compliance with law, testing and other related obligations of Tenant set forth in Article 7 of this Lease. In the event that the Building and Premises shall be surrendered in a condition which does not comply with the terms of this Section 15.4, because Tenant failed to comply with its obligations set forth in this Lease, then following thirty (30) days’ notice to Tenant, during which thirty (30) day period Tenant shall have the right to cure such noncompliance, Landlord shall be entitled to expend all reasonable costs in order to cause the same to comply with the required condition upon surrender and Tenant shall promptly reimburse Landlord for all such reasonable, out-of-pocket costs within thirty (30) days receipt of notice with backup documentation and, commencing on the later of the termination of this Lease and three (3) business days after Landlord’s delivery of notice of such failure and that it elects to treat such failure as a holdover, Tenant shall be deemed during the period that Tenant or Landlord, as the case may be, perform obligations relating to the Surrender Improvements to be in holdover under Article 16 of this Lease.

16. HOLDING OVER If Tenant holds over after the expiration of the Lease Term or earlier termination thereof, with the express or implied consent of Landlord, such tenancy shall be from month-to-month only, and shall not constitute a renewal hereof or an extension for any further term. If Tenant holds over after the expiration of the Lease Term of earlier termination thereof, without the express or implied consent of Landlord, such tenancy shall be deemed to be a tenancy by sufferance only, and shall not constitute a renewal hereof or an extension for any further term. In either case, Base Rent shall be payable at a monthly rate equal to one hundred fifty percent (150%) of the Base Rent applicable during the last rental period of the Lease Term under this Lease. Such month-to-month tenancy or tenancy by sufferance, as the case may be, shall be subject to every other applicable term, covenant and agreement contained herein. Nothing contained in this Article 16 shall be construed as consent by Landlord to any holding over by Tenant, and Landlord expressly reserves the right to require Tenant to surrender possession of the Premises to Landlord as provided in this Lease upon the expiration or other termination of this Lease. The provisions of this Article 16 shall not be deemed to limit or constitute a waiver of any other rights or remedies of Landlord provided herein or at law. If Tenant fails to surrender the Premises within forty-five (45) days following the termination or expiration of this Lease, in addition to any other liabilities to Landlord accruing therefrom, Tenant shall protect, defend, indemnify and hold Landlord harmless from all loss, costs (including reasonable attorneys’ fees) and liability resulting from such failure, including, without limiting the generality of the foregoing, any claims made by any succeeding tenant founded upon such failure to surrender and any lost profits to Landlord resulting therefrom.

17. ESTOPPEL CERTIFICATES Within ten (10) business days following a request in writing by Landlord, Tenant shall execute, acknowledge and deliver to Landlord an estoppel certificate, which, as submitted by Landlord, shall be substantially in the form of Exhibit D, attached hereto (or such other form as may be reasonably required by any prospective mortgagee or purchaser of the Project, or any portion thereof), indicating therein any exceptions thereto that may exist at that time, and shall also contain any other factual information reasonably requested by Landlord or Landlord’s mortgagee or prospective mortgagee. Any such certificate may be relied upon by any prospective mortgagee or purchaser of all or any portion of the Project. Tenant shall execute and deliver whatever other instruments may be reasonably required for such purposes. At any time during the Lease Term, in connection with a sale or financing of the Building by Landlord, Landlord may require Tenant to provide Landlord with a current financial statement and financial statements of the two (2) years prior to the current financial statement year. Such statements shall be prepared in accordance with generally accepted accounting principles and, if such is the normal practice of Tenant, shall be audited by an independent certified public accountant. Landlord shall hold such financial statements confidential. If Tenant fails to execute, acknowledge and deliver such estoppel certificate or other instruments within such ten (10) business day period after delivery of Landlord’ s written request and Landlord delivers a second written request for the same, then the failure of Tenant to execute, acknowledge and deliver such estoppel certificate or other instruments within four (4) business days after delivery of said second written request shall constitute an acknowledgment by Tenant that statements included in the estoppel certificate are true and correct, without exception.

18. SUBORDINATION Landlord hereby represents and warrants to Tenant that the Project is not currently subject to any ground lease, or to the lien of any mortgage or deed of trust. This Lease shall be subject and subordinate to all present and future ground or underlying leases of the Building or Project and to the lien of any mortgage, trust deed or other encumbrances now or hereafter in force against the Building or Project or any part thereof, if any, and to all renewals, extensions, modifications, consolidations and replacements thereof, and to all advances made or hereafter to be made upon the security of such mortgages or trust deeds, unless the holders of such mortgages, trust deeds or other encumbrances, or the lessors under such ground lease or underlying leases, require in writing that this Lease be superior thereto. The subordination of this Lease to any such future ground or underlying leases of the Building or Project or to the lien of any mortgage, trust deed or other encumbrances, shall be subject to Tenant’s receipt of a commercially reasonable subordination, non-disturbance, and attornment agreement in favor of Tenant. Tenant covenants and agrees in the event any proceedings are brought for the foreclosure of any such mortgage or deed in lieu thereof (or if any ground lease is terminated), to attorn, without any deductions or set-offs whatsoever, to the lienholder or purchaser or any successors thereto upon any such foreclosure sale or deed in lieu thereof (or to the ground lessor), if so requested to do so by such purchaser or lienholder or ground lessor, and to recognize such purchaser or lienholder or ground lessor as the lessor under this Lease, provided such lienholder or purchaser or ground lessor shall agree to accept this Lease and not disturb Tenant’s occupancy, so long as Tenant timely pays the rent and observes and performs the terms, covenants and conditions of this Lease to be observed and performed by Tenant. Landlord’s interest herein may be assigned as security at any time to any lienholder. Tenant shall, within ten (10) business days of written request by Landlord, execute such further instruments or assurances as Landlord may reasonably deem necessary to evidence or confirm the subordination or superiority of this Lease to any such mortgages, trust deeds, ground leases or underlying leases. Tenant waives the provisions of any current or future statute, rule or law which may give or purport to give Tenant any right or election to terminate or otherwise adversely affect this Lease and the obligations of the Tenant hereunder in the event of any foreclosure proceeding or sale.

19. DEFAULTS; REMEDIES

19.1 Events of Default. The occurrence of any of the following shall constitute a default of this Lease by Tenant:

19.1.1 Any failure by Tenant to pay any Rent or any other charge required to be paid under this Lease, or any part thereof, when due unless such failure is cured within five (5) business days after written notice to Tenant; or

19.1.2 Except where a specific time period is otherwise set forth for Tenant’s performance in this Lease, in which event the failure to perform by Tenant within such time period shall be a default by Tenant under this Section 19.1.2, any failure by Tenant to observe or perform any other provision, covenant or condition of this Lease to be observed or performed by Tenant where such failure continues for thirty (30) days after written notice thereof from Landlord to Tenant; provided that if the nature of such default is such that the same cannot reasonably be cured within a thirty (30) day period, Tenant shall not be deemed to be in default if it diligently commences such cure within such period and thereafter diligently proceeds to rectify and cure such default; or

19.1.3 Abandonment (as defined in California Civil Code Section 1951.3 or any successor statute)of all or a substantial portion of the Premises by Tenant; or

19.1.4 The failure by Tenant to observe or perform according to the provisions of Articles 5, 14, 17 or 18 of this Lease where such failure continues for more than five (5) business days after notice from Landlord.

The notice periods provided herein are in lieu of, and not in addition to, any notice periods provided by law.

19.2 Remedies Upon Default. Upon the occurrence of any event of default by Tenant beyond any applicable notice and cure periods, Landlord shall have, in addition to any other remedies available to Landlord at law or in equity (all of which remedies shall be distinct, separate and cumulative), the option to pursue any one or more of the following remedies, each and all of which shall be cumulative and nonexclusive, without any notice or demand whatsoever.

19.2.1 Terminate this Lease, in which event Tenant shall immediately surrender the Premises to Landlord, and if Tenant fails to do so, Landlord may, without prejudice to any other remedy which it may have for possession or arrearages in rent, enter upon and take possession of the Premises and expel or remove Tenant and any other person who may be occupying the Premises or any part thereof, without being liable for prosecution or any claim or damages therefor; and Landlord may recover from Tenant the following:

(i) The worth at the time of award of the unpaid rent which has been earned at the time of such termination; plus

(ii) The worth at the time of award of the amount by which the unpaid rent which would have been earned after termination until the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus

(iii) The worth at the time of award of the amount by which the unpaid rent for the balance of the Lease Term after the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus

Britannia Biotech Gateway Business Park

[Britannia Gateway Business Park]

[Senti Biosciences, Inc.]

(iv) Any other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant’s failure to perform its obligations under this Lease or which in the ordinary course of things would be likely to result therefrom, specifically including but not limited to, in each case to the extent allocable to the remaining Lease Term, brokerage commissions and advertising expenses incurred to obtain a new tenant, expenses of remodeling the Premises or any portion thereof for a new tenant, whether for the same or a different use, and any special concessions made to obtain a new tenant; and

(v) At Landlord’s election, such other amounts in addition to or in lieu of the foregoing as may be permitted from time to time by applicable law.

The term “rent” as used in this Section 19.2 shall be deemed to be and to mean all sums of every nature required to be paid by Tenant pursuant to the terms of this Lease, whether to Landlord or to others. As used in Sections 19.2.1(i) and (ii), above, the “worth at the time of award” shall be computed by allowing interest at the rate set forth in Article 25 of this Lease, but in no case greater than the maximum amount of such interest permitted by law. As used in Section 19.2.1(iii) above, the “worth at the time of award” shall be computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of award plus one percent (1%).

19.2.2 Landlord shall have the remedy described in California Civil Code Section 1951.4 (lessor may continue lease in effect after lessee’s breach and abandonment and recover rent as it becomes due, if lessee has the right to sublet or assign, subject only to reasonable limitations). Accordingly, if Landlord does not elect to terminate this Lease on account of any default by Tenant, Landlord may, from time to time, without terminating this Lease, enforce all of its rights and remedies under this Lease, including the right to recover all rent as it becomes due.

19.2.3 Landlord shall at all times have the rights and remedies (which shall be cumulative with each other and cumulative and in addition to those rights and remedies available under Sections 19.2.1 and 19.2.2, above, or any law or other provision of this Lease), without prior demand or notice except as required by Applicable Law, to seek any declaratory, injunctive or other equitable relief, and specifically enforce this Lease, or restrain or enjoin a violation or breach of any provision hereof.

19.3 Subleases of Tenant. Whether or not Landlord elects to terminate this Lease on account of any default by Tenant, as set forth in this Article 19, Landlord shall have the right to terminate any and all subleases, licenses, concessions or other consensual arrangements for possession entered into by Tenant and affecting the Premises or may, in Landlord’s sole discretion, succeed to Tenant’s interest in such subleases, licenses, concessions or arrangements. In the event of Landlord’s election to succeed to Tenant’s interest in any such subleases, licenses, concessions or arrangements, Tenant shall, as of the date of notice by Landlord of such election, have no further right to or interest in the rent or other consideration receivable thereunder.

19.4 Efforts to Relet. No re-entry or repossession, repairs, maintenance, changes, alterations and additions, reletting, appointment of a receiver to protect Landlord’s interests hereunder, or any other action or omission by Landlord shall be construed as an election by Landlord to terminate this Lease or Tenant’s right to possession, or to accept a surrender of the Premises, nor shall same operate to release Tenant in whole or in part from any of Tenant’s obligations hereunder, unless express written notice of such intention is sent by Landlord to Tenant.

19.5 Landlord Default.

19.5.1 General. Notwithstanding anything to the contrary set forth in this Lease, Landlord shall not be in default in the performance of any obligation required to be performed by Landlord pursuant to this Lease unless Landlord fails to perform such obligation within thirty (30) days after the receipt of notice from Tenant specifying in detail Landlord’s failure to perform; provided, however, if the nature of Landlord’s obligation is such that more than thirty (30) days are required for its performance, then Landlord shall not be in default under this Lease if it shall commence such performance within such thirty (30) day period and thereafter diligently pursue the same to completion. Upon any such default by Landlord under this Lease, Tenant may, except as otherwise specifically provided in this Lease to the contrary, exercise any of its rights provided at law or in equity.

19.5.2 Abatement of Rent. In the event that Tenant is prevented from using, and does not use, the Premises or any portion thereof, as a result of (i) any repair, maintenance or alteration performed by Landlord, or which Landlord failed to perform, after the Lease Commencement Date and required by this Lease, which substantially interferes with Tenant’s use of the Premises, or (ii) any failure to provide services, utilities or access to the Premises to the extent required by this Lease, each as a direct result of Landlord’s negligence or willful misconduct (and except to the extent such failure is caused in whole or in part by the action or inaction of Tenant) (either such set of circumstances as set forth in items (i) or (ii), above, to be known as an “Abatement Event”), then Tenant shall give Landlord notice of such Abatement Event, and if such Abatement Event continues for ten (10) consecutive business days after Landlord’s receipt of any such notice (the “Eligibility Period”) and Landlord does not diligently commence and pursue to completion the remedy of such Abatement Event, then the Base Rent, Tenant’s Share of Direct Expenses, and Tenant’s obligation, if any, to pay for parking (to the extent not utilized by Tenant) shall be abated or reduced, as the case may be, after expiration of the Eligibility Period for such time that Tenant continues to be so prevented from using, and does not use for the normal conduct of Tenant’s business, the Premises or a portion thereof, in the proportion that the rentable area of the portion of the Premises that Tenant is prevented from using, and does not use, bears to the total rentable area of the Premises; provided, however, in the event that Tenant is prevented from using, and does not use, a portion of the Premises for a period of time in excess of the Eligibility Period and the remaining portion of the Premises is not sufficient to allow Tenant to effectively conduct its business therein, and if Tenant does not effectively conduct its business from such remaining portion, then for such time after expiration of the Eligibility Period during which Tenant is so prevented from effectively conducting its business therein, the Base Rent and Tenant’s Share of Direct Expenses for the entire Premises and Tenant’s obligation to pay for parking shall be abated for such time as Tenant continues to be so prevented from using, and does not use, the Premises. If, however, Tenant reoccupies any portion of the Premises during such period, the Rent allocable to such reoccupied portion, based on the proportion that the rentable area of such reoccupied portion of the Premises bears to the total rentable area of the Premises, shall be payable by Tenant from the date Tenant reoccupies such portion of the Premises. To the extent an Abatement Event is caused by an event covered by Articles 5, 11 or 13 of this Lease, then Tenant’s right to abate rent shall be governed by the terms of such Article 5, 11 or 13, as applicable, and the Eligibility Period shall not be applicable thereto. Such right to abate Base Rent and Tenant’s Share of Direct Expenses shall be Tenant’s sole and exclusive remedy for rent abatement at law or in equity for an Abatement Event. Except as provided in this Section 19.5.2, nothing contained herein shall be interpreted to mean that Tenant is excused from paying Rent due hereunder.

20. COVENANT OF QUIET ENJOYMENT Landlord covenants that Tenant, on paying the Rent, charges for services and other payments herein reserved and on keeping, observing and performing all the other terms, covenants, conditions, provisions and agreements herein contained on the part of Tenant to be kept, observed and performed, shall, during the Lease Term, peaceably and quietly have, hold and enjoy the Premises subject to the terms, covenants, conditions, provisions and agreements hereof without interference by any persons lawfully claiming by or through Landlord. The foregoing covenant is in lieu of any other covenant express or implied.

21. LETTER OF CREDIT

21.1 Delivery of Letter of Credit. Tenant shall deliver to Landlord, concurrently with Tenant’s execution of this Lease, an unconditional, clean, irrevocable letter of credit (the “L-C”) in the amount set forth in Section 8 of the Lease Summary (the “L-C Amount”), which L-C shall be issued by a money-center, solvent and nationally recognized bank (a bank which accepts deposits, maintains accounts, has a local San Francisco Bay Area office which will negotiate a letter of credit, and whose deposits are insured by the FDIC) reasonably acceptable to Landlord (such approved, issuing bank being referred to herein as the “Bank”), which Bank must have a rating from Standard and Poors Corporation of A- or better (or any equivalent rating thereto from any successor or substitute rating service selected by Lessor) and a letter of credit issuer rating from Moody’s Investor Service of A3 or better (or any equivalent rating thereto from any successor rating agency thereto)) (collectively, the “Bank’s Credit Rating Threshold”), and which L-C shall be substantially in the form of Exhibit F, attached hereto. Tenant shall pay all expenses, points and/or fees incurred by Tenant in obtaining the L-C. The L-C shall (i) be “callable” at sight, irrevocable and unconditional, (ii) be maintained in effect, whether through renewal or extension, for the period commencing on the date of this Lease and continuing until the date (the “L-C Expiration Date”) that is no less than one hundred twenty (120) days after the expiration of the Lease Term as the same may be extended, and Tenant shall deliver a new L-C or certificate of renewal or extension to Landlord at least forty-five (45) days prior to the expiration of the L-C then held by Landlord, without any action whatsoever on the part of Landlord, (iii) be fully assignable by Landlord, its successors and assigns, (iv) permit partial draws and multiple presentations and drawings, and (v) be otherwise subject to the Uniform Customs and Practices for Documentary Credits (1993-Rev), International Chamber of Commerce Publication #500, or the International Standby Practices-ISP 98, International Chamber of Commerce Publication #590. Landlord, or its then managing agent, shall have the right to draw down an amount up to the face amount of the L-C if any of the following shall have occurred or be applicable: (A) such amount is due to Landlord under the terms and conditions of this Lease, and has not been paid within applicable notice and cure periods (or, if Landlord is prevented by law from providing notice, within the period for payment set forth in the Lease), or (B) Tenant has filed a voluntary petition under the U. S. Bankruptcy Code or any state bankruptcy code (collectively, “Bankruptcy Code”), or (C) an involuntary petition has been filed against Tenant under the Bankruptcy Code that is not dismissed within thirty (30) days, or (D) the Lease has been rejected, or is deemed rejected, under Section 365 of the U.S. Bankruptcy Code, following the filing of a voluntary petition by Tenant under the Bankruptcy Code, or the filing of an involuntary petition against Tenant under the Bankruptcy Code, or (E) the Bank has notified Landlord that the L-C will not be renewed or extended through the L-C Expiration Date, and Tenant has not provided a replacement L-C that satisfies the requirements of this Lease at least thirty (30) days prior to such expiration, or (F) Tenant is placed into receivership or conservatorship, or becomes subject to similar proceedings under Federal or State law, or (G) Tenant executes an assignment for the benefit of creditors, or (H) if (1) any of the Bank’s Fitch Ratings (or other comparable ratings to the extent the Fitch Ratings are no longer available) have been reduced below the Bank’s Credit Rating Threshold, or (2) there is otherwise a material adverse change in the financial condition of the Bank, and Tenant has failed to provide Landlord with a replacement letter of credit, conforming in all respects to the requirements of this Article 21 (including, but not limited to, the requirements placed on the issuing Bank more particularly set forth in this Section 21.1 above), in the amount of the applicable L-C Amount, within ten (10) business days following Landlord’s written demand therefor (with no other notice or cure or grace period being applicable thereto, notwithstanding anything in this Lease to the contrary) (each of the foregoing being an “L-C Draw Event”). The L-C shall be honored by the Bank regardless of whether Tenant disputes Landlord’s right to draw upon the L-C. In addition, in the event the Bank is placed into receivership or conservatorship by the Federal Deposit Insurance Corporation or any successor or similar entity, then, effective as of the date such receivership or conservatorship occurs, said L-C shall be deemed to fail to meet the requirements of this Article 21, and, within ten (10) business days following Landlord’s notice to Tenant of such receivership or conservatorship (the “L-C FDIC Replacement Notice”), Tenant shall replace such L-C with a substitute letter of credit from a different issuer (which issuer shall meet or exceed the Bank’s Credit Rating Threshold and shall otherwise be acceptable to Landlord in its reasonable discretion) and that complies in all respects with the requirements of this Article 21. If Tenant fails to replace such L-C with such conforming, substitute letter of credit pursuant to the terms and conditions of this Section 21.1, then, notwithstanding anything in this Lease to the contrary, Landlord shall have the right to declare Tenant in default of this Lease for which there shall be no notice or grace or cure periods being applicable thereto (other than the aforesaid ten (10) day period). Tenant shall be responsible for the payment of any and all Tenant’s and Bank’s costs incurred with the review of any replacement L-C, which replacement is required pursuant to this Section or is otherwise requested by Tenant. In the event of an assignment by Tenant of its interest in the Lease (and irrespective of whether Landlord’s consent is required for such assignment), the acceptance of any replacement or substitute letter of credit by Landlord from the assignee shall be subject to Landlord’s prior written approval, in Landlord’s reasonable discretion, and the actual and reasonable attorney’s fees incurred by Landlord in connection with such determination shall be payable by Tenant to Landlord within ten (10) business days of billing.

21.2 Application of L-C. Tenant hereby acknowledges and agrees that Landlord is entering into this Lease in material reliance upon the ability of Landlord to draw upon the L-C upon the occurrence of any L-C Draw Event. In the event of any L-C Draw Event, Landlord may, but without obligation to do so, and without notice to Tenant (except in connection with an L-C Draw Event under Section 21.1(H) above), draw upon the L-C, in part or in whole, in the amount reasonably necessary to cure any such L-C Draw Event and/or to compensate Landlord for any and all damages of any kind or nature sustained or which Landlord reasonably estimates that it will sustain resulting from Tenant’s breach or default of the Lease beyond any applicable notice and cure periods or other L-C Draw Event and/or to compensate Landlord for any and all damages arising out of, or incurred in connection with, the termination of this Lease, including, without limitation, those specifically identified in Section 1951.2 of the California Civil Code. The use, application or retention of the L-C, or any portion thereof, by Landlord shall not prevent Landlord from exercising any other right or remedy provided by this Lease or by any Applicable Law, it being intended that Landlord shall not first be required to proceed against the L-C, and such L-C shall not operate as a limitation on any recovery to which Landlord may otherwise be entitled. Tenant agrees and acknowledges that (i) the L-C constitutes a separate and independent contract between Landlord and the Bank, (ii) Tenant is not a third party beneficiary of such contract, (iii) Tenant has no property interest whatsoever in the L-C or the proceeds thereof, and (iv) in the event Tenant becomes a debtor under any chapter of the Bankruptcy Code, Tenant is placed into receivership or conservatorship, and/or there is an event of a receivership, conservatorship or a bankruptcy filing by, or on behalf of, Tenant, neither Tenant, any trustee, nor Tenant’s bankruptcy estate shall have any right to restrict or limit Landlord’s claim and/or rights to the L-C and/or the proceeds thereof by application of Section 502(b)(6) of the U. S. Bankruptcy Code or otherwise.

21.3 Maintenance of L-C by Tenant. If, as a result of any drawing by Landlord of all or any portion of the L-C, the amount of the L-C shall be less than the L-C Amount, Tenant shall, within ten (10) business days thereafter, provide Landlord with additional letter(s) of credit in an amount equal to the deficiency, and any such additional letter(s) of credit shall comply with all of the provisions of this Article 21. Tenant further covenants and warrants that it will neither assign nor encumber the L-C or any part thereof and that neither Landlord nor its successors or assigns will be bound by any such assignment, encumbrance, attempted assignment or attempted encumbrance. Without limiting the generality of the foregoing, if the L-C expires earlier than the L-C Expiration Date, Landlord will accept a renewal thereof (such renewal letter of credit to be in effect and delivered to Landlord, as applicable, not later than thirty (30) days prior to the expiration of the L-C), which shall be irrevocable and automatically renewable as above provided through the L-C Expiration Date upon substantially the same terms as the expiring L-C or such other terms as may be acceptable to Landlord in its reasonable discretion. If Tenant exercises its option to extend the Lease Term pursuant to Section 2.2 of this Lease then, not later than thirty (30) days prior to the commencement of the Option Term, Tenant shall deliver to Landlord a new L C or certificate of renewal or extension evidencing the L-C Expiration Date as thirty (30) days after the expiration of the Option Term. However, if the L-C is not timely renewed, or if Tenant fails to maintain the L-C in the amount and in accordance with the terms set forth in this Article 21, Landlord shall have the right to present the L-C to the Bank in accordance with the terms of this Article 21, and the proceeds of the L-C may be applied by Landlord against any Rent payable by Tenant under this Lease that is not paid when due and/or to pay for all losses and damages that Landlord has suffered as a result of any breach or default by Tenant under this Lease. In the event Landlord elects to exercise its rights as provided above, (I) any unused proceeds shall constitute the property of Landlord (and not Tenant’s property or, in the event of a receivership, conservatorship, or a bankruptcy filing by, or on behalf of, Tenant, property of such receivership, conservatorship or Tenant’s bankruptcy estate) and need not be segregated from Landlord’s other assets, and (II) Landlord agrees to pay to Tenant within thirty (30) days after the L-C Expiration Date the amount of any proceeds of the L-C received by Landlord and not applied against any Rent payable by Tenant under this Lease that was not paid when due or used to pay for any losses and/or damages suffered by Landlord as a result of any breach or default by Tenant under this Lease beyond any applicable notice and cure period; provided, however, that if prior to the L-C Expiration Date a voluntary petition is filed by Tenant, or an involuntary petition is filed against Tenant by any of Tenant’s creditors, under the Bankruptcy Code, then Landlord shall not be obligated to make such payment in the amount of the unused L-C proceeds until either all preference issues relating to payments under this Lease have been resolved in such bankruptcy or reorganization case or such bankruptcy or reorganization case has been dismissed. If Landlord draws on the L-C due to Tenant’s failure to timely renew or provide a replacement L-C, such failure shall not be considered a default under this Lease and Landlord shall return such cash proceeds upon Tenant’s presentation of a replacement L-C that satisfies the requirements of this Lease, subject to reasonable satisfaction of any preference risk to Landlord.

21.4 Transfer and Encumbrance. The L-C shall also provide that Landlord may, at any time and without notice to Tenant and without first obtaining Tenant’s consent thereto, transfer (one or more times) its interest in and to the L-C to another party, person or entity, provided such transfer is in connection with the assignment by Landlord of its rights and interests in and to this Lease. In the event of a transfer of Landlord’s interest under this Lease (other than in connection with a financing) and the transferee’s assumption of Landlord’s obligations under this Lease, Landlord shall transfer the L-C, in whole or in part, to the transferee and thereupon Landlord shall, without any further agreement between the parties, be released by Tenant from all liability therefor, and it is agreed that the provisions hereof shall apply to every transfer or assignment of the whole of said L-C to a new landlord. In connection with any such transfer of the L-C by Landlord, Tenant shall, at Tenant’s sole cost and expense, execute and submit to the Bank such applications, documents and instruments as may be necessary to effectuate such transfer and, Tenant shall be responsible for paying the Bank’s transfer and processing fees in connection therewith; provided that, Landlord shall have the right (in its sole discretion), but not the obligation, to pay such fees on behalf of Tenant, in which case Tenant shall reimburse Landlord within ten (10) days after Tenant’s receipt of an invoice from Landlord therefor.

21.5 L-C Not a Security Deposit. Landlord and Tenant (1) acknowledge and agree that in no event or circumstance shall the L-C or any renewal thereof or substitute therefor or any proceeds thereof be deemed to be or treated as a “security deposit” under any law applicable to security deposits in the commercial context, including, but not limited to, Section 1950.7 of the California Civil Code, as such Section now exists or as it may be hereafter amended or succeeded (the “Security Deposit Laws”), (2) acknowledge and agree that the L-C (including any renewal thereof or substitute therefor or any proceeds thereof) is not intended to serve as a security deposit, and the Security Deposit Laws shall have no applicability or relevancy thereto, and (3) waive any and all rights, duties and obligations that any such party may now, or in the future will, have relating to or arising from the Security Deposit Laws. Tenant hereby irrevocably waives and relinquishes the provisions of Section 1950.7 of the California Civil Code and any successor statute, and all other provisions of law, now or hereafter in effect, which (x) establish the time frame by which a landlord must refund a security deposit under a lease, and/or (y) provide that a landlord may claim from a security deposit only those sums reasonably necessary to remedy defaults in the payment of rent, to repair damage caused by a tenant or to clean the premises, it being agreed that Landlord may, in addition, claim those sums specified in this Article 21 and/or those sums reasonably necessary to (a) compensate Landlord for any loss or damage caused by Tenant’s breach of this Lease beyond any applicable notice and cure periods, including any damages Landlord suffers following termination of this Lease, and/or (b) compensate Landlord for any and all damages arising out of, or incurred in connection with, the termination of this Lease, including, without limitation, those specifically identified in Section 1951.2 of the California Civil Code. Tenant agrees not to interfere in any way with any payment to Landlord of the proceeds of the L-C, either prior to or following a “draw” by Landlord of all or any portion of the L-C, regardless of whether any dispute exists between Tenant and Landlord as to Landlord’s right to draw down all or any portion of the L-C. No condition or term of this Lease shall be deemed to render the L-C conditional and thereby afford the Bank a justification for failing to honor a drawing upon such L-C in a timely manner. Tenant shall not request or instruct the Bank of any L-C to refrain from paying sight draft(s) drawn under such L-C.

21.6 Non-Interference By Tenant. Tenant agrees not to interfere in any way with any payment to Landlord of the proceeds of the L-C, either prior to or following a “draw” by Landlord of all or any portion of the L¬C, regardless of whether any dispute exists between Tenant and Landlord as to Landlord’s right to draw down all or any portion of the L-C. No condition or term of this Lease shall be deemed to render the L-C conditional and thereby afford the Bank a justification for failing to honor a drawing upon such L-C in a timely manner. Tenant shall not request or instruct the Bank of any L-C to refrain from paying sight draft(s) drawn under such L-C.

21.7 Waiver of Certain Relief. Tenant unconditionally and irrevocably waives (and as an independent covenant hereunder, covenants not to assert) any right to claim or obtain any of the following relief in connection with the L-C:

21.7.1 A temporary restraining order, temporary injunction, permanent injunction, or other order that would prevent, restrain or restrict the presentment of sight drafts drawn under any L-C or the Bank’s honoring or payment of sight draft(s); or

21.7.2 Any attachment, garnishment, or levy in any manner upon either the proceeds of any L-C or the obligations of the Bank (either before or after the presentment to the Bank of sight drafts drawn under such L-C) based on any theory whatever.

21.8 Remedy for Improper Drafts. Tenant’s sole remedy in connection with the improper presentment or payment of sight drafts drawn under any L-C shall be the right to obtain from Landlord a refund of the amount of any sight draft(s) that were improperly presented or the proceeds of which were misapplied, and reasonable actual out-of-pocket attorneys’ fees, provided that at the time of such refund, Tenant increases the amount of such L-C to the amount (if any) then required under the applicable provisions of this Lease. Tenant acknowledges that the presentment of sight drafts drawn under any L-C, or the Bank’s payment of sight drafts drawn under such L-C, could not under any circumstances cause Tenant injury that could not be remedied by an award of money damages, and that the recovery of money damages would be an adequate remedy therefor. In the event Tenant shall be entitled to a refund as aforesaid and Landlord shall fail to make such payment within ten (10) business days after demand, Tenant shall have the right to deduct the amount thereof from the next installment(s) of Base Rent.

22. COMMUNICATIONS AND COMPUTER LINE Tenant may install, maintain, replace, remove or use any communications or computer wires and cables serving the Premises (collectively, the “Lines”), provided that Tenant shall obtain Landlord’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed, use an experienced and qualified contractor approved in writing by Landlord, and comply with all of the other provisions of Articles 7 and 8 of this Lease. Tenant shall pay all costs in connection therewith. Landlord reserves the right, upon notice to Tenant prior to the expiration or earlier termination of this Lease, to require that Tenant, at Tenant’s sole cost and expense, remove any Lines located in or serving the Premises prior to the expiration or earlier termination of this Lease.

23. SIGNS

23.1 Exterior Signage. Subject to Landlord’s prior written approval, which shall not be unreasonably withheld, conditioned or delayed, and provided all signs are in keeping with the quality, design and style of the Building and Project, Tenant, at its sole cost and expense, may install (i) identification signage on a monument sign located at the exterior of the Building near the Project entry, and at the entrance to the Building, and (ii) internal directional, suite entry and lobby identification signage and directory (collectively, “Tenant Signage”); provided, however, in no event shall Tenant’s Signage include an “Objectionable Name,” as that term is defined in Section 23.3, of this Lease. All such signage shall be subject to Tenant’s obtaining all required governmental approvals. All permitted signs shall be maintained by Tenant at its expense in a first-class and safe condition and appearance. Upon the expiration or earlier termination of this Lease, Tenant shall remove all of its signs at Tenant’s sole cost and expense. The graphics, materials, color, design, lettering, lighting, size, illumination, specifications and exact location of Tenant’s Signage (collectively, the “Sign Specifications”) shall be subject to the prior written approval of Landlord, which approval shall not be unreasonably withheld, conditioned or delayed, and shall be consistent and compatible with the quality and nature of the Project. Tenant hereby acknowledges that, notwithstanding Landlord’s approval of Tenant’s Signage, Landlord has made no representation or warranty to Tenant with respect to the probability of obtaining all necessary governmental approvals and permits for Tenant’s Signage. In the event Tenant does not receive the necessary governmental approvals and permits for Tenant’s Signage, Tenant’s and Landlord’s rights and obligations under the remaining terms and conditions of this Lease shall be unaffected.

23.2 Objectionable Name. Tenant’s Signage shall not include a name or logo which relates to an entity which is of a character or reputation, or is associated with a political faction or orientation, which is inconsistent with the quality of the Project, or which would otherwise reasonably offend a landlord of the Comparable Buildings (an “Objectionable Name”). The parties hereby agree that the following name, or any reasonable derivation thereof, shall be deemed not to constitute an Objectionable Name: “Senti Biosciences, Inc..”

23.3 Prohibited Signage and Other Items. Any signs, notices, logos, pictures, names or advertisements which are installed and that have not been separately approved by Landlord may be removed without notice by Landlord at the sole expense of Tenant. Any signs, window coverings, or blinds (even if the same are located behind the Landlord-approved window coverings for the Building), or other items visible from the exterior of the Premises or Building, shall be subject to the prior approval of Landlord, in its sole discretion.

24. COMPLIANCE WITH LAW

24.1 In General. Landlord shall comply with all “Applicable Laws” (defined below) relating to the Base Building and Common Areas, provided that compliance with such Applicable Laws is not the responsibility of Tenant under this Lease, and provided further that, as between Landlord and Tenant, Landlord shall not be deemed to be in default of the Lease as a result of the failure to comply with any Applicable Laws unless Landlord’s failure to comply therewith would prohibit Tenant from obtaining or maintaining a certificate of occupancy for the Premises, would materially affect the safety of Tenant’s employees or create a material health hazard for Tenant’s employees, or would otherwise result in any material cost or liability to Tenant. The “Base Building” shall include the structural portions of the Building, and the public restrooms, elevators, exit stairwells and the systems and equipment located in the internal core of the Building on the floor or floors on which the Premises is located. Tenant shall not do anything or suffer anything to be done in or about the Premises or the Project which will in any way conflict with any law, statute, ordinance or other governmental rule, regulation or requirement now in force or which may hereafter be enacted or promulgated (“Applicable Laws”). At its sole cost and expense, Tenant shall promptly comply with all such Applicable Laws (including the making of any alterations to the Premises required by Applicable Laws) which relate to (i) Tenant’s use of the Premises, (ii) the Alterations or the Tenant Improvements (provided the initial construction of the Tenant Improvements shall be performed by Landlord pursuant to the Tenant Work Letter) in the Premises, or (iii) the Base Building (which shall include the Building structure, and the public restrooms, elevators, exit stairwells and the Building systems located in the internal core of the Buildings on the floor or floors on which the Premises is located), but, as to the Base Building, only to the extent such obligations are triggered by Tenant’s Alterations, the Tenant Improvements, or Tenant’s particular use of the Premises. Should any standard or regulation now or hereafter be imposed on Landlord or Tenant by a state, federal or local governmental body charged with the establishment, regulation and enforcement of occupational, health or safety standards for employers, employees, landlords or tenants, then Tenant agrees, at its sole cost and expense, to comply promptly with such standards or regulations. The judgment of any court of competent jurisdiction or the admission of Tenant in any judicial action, regardless of whether Landlord is a party thereto, that Tenant has violated any of said governmental measures, shall be conclusive of that fact as between Landlord and Tenant.

24.2 Certified Access Specialist. For purposes of Section 1938 of the California Civil Code, Landlord hereby discloses to Tenant, and Tenant hereby acknowledges, that the Project, Building and Premises have not undergone inspection by a Certified Access Specialist (CASp). As required by Section 1938(e) of the California Civil Code, Landlord hereby states as follows: “A Certified Access Specialist (CASp) can inspect the subject premises and determine whether the subject premises comply with all of the applicable construction-related accessibility standards under state law. Although state law does not require a CASp inspection of the subject premises, the commercial property owner or lessor may not prohibit the lessee or tenant from obtaining a CASp inspection of the subject premises for the occupancy or potential occupancy of the lessee or tenant, if requested by the lessee or tenant. The parties shall mutually agree on the arrangements for the time and manner of the CASp inspection, the payment of the fee for the CASp inspection, and the cost of making any repairs necessary to correct violations of construction-related accessibility standards within the premises.” In furtherance of the foregoing, Landlord and Tenant hereby agree as follows: (a) any CASp inspection requested by Tenant shall be conducted, at Tenant’s sole cost and expense, by a CASp approved in advance by Landlord, such approval not to be unreasonably withheld, conditioned or delayed; and (b) pursuant to this Article 24, Tenant, at its cost, is responsible for making any repairs within the Premises to correct violations of construction-related accessibility standards; and, if anything done by or for Tenant in its use or occupancy of the Premises shall require repairs to the Building (outside the Premises) to correct violations of construction-related accessibility standards, then Tenant shall, at Landlord’s option, either perform such repairs at Tenant’s sole cost and expense or reimburse Landlord upon demand, as Additional Rent, for the cost to Landlord of performing such repairs. The terms of this Section 24.2 do not amend or reduce the obligations of Landlord and Tenant set forth in this Lease regarding compliance with Applicable Laws generally and repair and maintenance of the Premises and the Project or the initial construction of the Tenant Improvements pursuant to the Tenant Work Letter, but apply solely to the obligations of Landlord and Tenant in connection with Tenant’s election to conduct a CASp inspection hereunder.

25. LATE CHARGES If any installment of Rent or any other sum due from Tenant shall not be received by Landlord or Landlord’s designee within five (5) business days after Tenant’s receipt of written notice from Landlord that said amount is due, then Tenant shall pay to Landlord a late charge equal to five percent (5%) of the overdue amount plus any reasonable attorneys’ fees incurred by Landlord by reason of Tenant’s failure to pay Rent and/or other charges when due hereunder. Notwithstanding the foregoing, the first late payment by Tenant in any twelve (12) month period shall not be subject to such late charge. The late charge shall be deemed Additional Rent and the right to require it shall be in addition to all of Landlord’s other rights and remedies hereunder or at law and shall not be construed as liquidated damages or as limiting Landlord’s remedies in any manner. In addition to the late charge described above, any Rent or other amounts owing hereunder which are not paid within ten (10) days after the date they are due shall bear interest from the date when due until paid at a rate per annum equal to the lesser of (i) the annual “Bank Prime Loan” rate cited in the Federal Reserve Statistical Release Publication G.13(415), published on the first Tuesday of each calendar month (or such other comparable index as Landlord and Tenant shall reasonably agree upon if such rate ceases to be published) plus four (4) percentage points, and (ii) the highest rate permitted by Applicable Law. Notwithstanding the foregoing, the first late payment by Tenant in any twelve (12) month period shall not be subject to such interest.

26. LANDLORD’S RIGHT TO CURE DEFAULT; PAYMENTS BY TENANT

26.1 Landlord’s Cure. All covenants and agreements to be kept or performed by Tenant under this Lease shall be performed by Tenant at Tenant’s sole cost and expense and without any reduction of Rent, except to the extent, if any, otherwise expressly provided herein. If Tenant shall fail to perform any obligation under this Lease, and such failure shall continue in excess of the time allowed under Section 19.1.2, above, unless a specific time period is otherwise stated in this Lease, Landlord may, but shall not be obligated to, make any such payment or perform any such act on Tenant’s part without waiving its rights based upon any default of Tenant and without releasing Tenant from any obligations hereunder.

26.2 Tenant’s Reimbursement. Except as may be specifically provided to the contrary in this Lease, Tenant shall pay to Landlord, upon delivery by Landlord to Tenant of statements therefor: (i) sums equal to expenditures reasonably made and obligations incurred by Landlord in connection with the remedying by Landlord of Tenant’s defaults pursuant to the provisions of Section 26.1; (ii) sums equal to all losses, costs, liabilities, damages and expenses referred to in Article 10 of this Lease; and (iii) sums equal to all expenditures made and obligations incurred by Landlord in collecting or attempting to collect the Rent or in enforcing or attempting to enforce any rights of Landlord under this Lease or pursuant to law, including, without limitation, all reasonable legal fees and other amounts so expended. Tenant’s obligations under this Section 26.2 shall survive the expiration or sooner termination of the Lease Term.

27. ENTRY BY LANDLORD Landlord reserves the right at all reasonable times and upon not less than twenty-four (24) hours’ notice to Tenant (except in the case of an emergency) to enter the Premises to (i) inspect them; (ii) show the Premises to prospective purchasers, or to current or prospective mortgagees, ground or underlying lessors or insurers or, during the last nine (9) months of the Lease Term, to prospective tenants; (iii) post notices of nonresponsibility (to the extent applicable pursuant to then Applicable Law); or (iv) alter, improve or repair the Premises or the Building, or for structural alterations, repairs or improvements to the Building or the Building’s systems and equipment. Landlord may make any such entries without the abatement of Rent, except as otherwise provided in this Lease, and may take such reasonable steps as required to accomplish the stated purposes. In an emergency, Landlord shall have the right to use any means that Landlord may deem proper to open the doors in and to the Premises. Any entry into the Premises by Landlord in the manner hereinbefore described shall not be deemed to be a forcible or unlawful entry into, or a detainer of, the Premises, or an actual or constructive eviction of Tenant from any portion of the Premises. Landlord shall use commercially reasonable efforts to minimize any interference with Tenant’s use of or access to the Premises in connection with any such entry, and shall comply with Tenant’s reasonable security measures. Landlord shall hold confidential any information regarding Tenant’s business that it may learn as a result of such entry. Landlord acknowledges and agrees that Tenant may require that Landlord be accompanied by an employee of Tenant during any such entry into the Premises by Landlord (except in the event of an emergency in which case no escort shall be required); provided, however, that in no event shall the unavailability of such escort at the time that Landlord is permitted to enter the Premises delay Landlord’s entry into the Premises as permitted hereunder.

28. TENANT PARKING Tenant shall have the right, without the payment of any parking charge or fee (other than as a reimbursement of Operating Expenses to the extent allowed pursuant to the terms or Article 4), commencing on the Rent Commencement Date, to use the amount of parking set forth in Section 9 of the Summary, in the on-site and/or off-site, as the case may be, parking facility (or facilities) which serve the Project. Tenant shall abide by all reasonable rules and regulations which are prescribed from time to time for the orderly operation and use of the parking facility where the parking passes are located (including any sticker or other identification system established by Landlord and the prohibition of vehicle repair and maintenance activities in the parking facilities) (provided that such rules and regulations are not discriminatorily applied vis-à-vis Tenant), and shall cooperate in seeing that Tenant’s employees and visitors also comply with such rules and regulations. Tenant’s use of the Project parking facility shall be at Tenant’s sole risk and Tenant acknowledges and agrees that Landlord shall have no liability whatsoever for damage to the vehicles of Tenant, its employees and/or visitors, or for other personal injury or property damage or theft relating to or connected with the parking rights granted herein or any of Tenant’s, its employees’ and/or visitors’ use of the parking facilities, except to the extent arising from the negligence or willful misconduct of Landlord or the Landlord Parties.

29.4 Modification of Lease. Should any current or prospective mortgagee or ground lessor for the Building or Project require a modification of this Lease, which modification will not cause an increased cost or expense to Tenant or in any other way materially and adversely change the rights and obligations of Tenant hereunder or Tenant’s use of the Premises, then and in such event, Tenant agrees that this Lease may be so modified and agrees to execute whatever documents are reasonably required therefor and to deliver the same to Landlord within ten (10) business days following a request therefor. At the request of Landlord or any mortgagee or ground lessor, Tenant agrees to execute a short form of Lease and deliver the same to Landlord within ten (10) business days following the request therefor.

29.12 No Warranty. In executing and delivering this Lease, Tenant has not relied on any representations, including, but not limited to, any representation as to the amount of any item comprising Additional Rent or the amount of the Additional Rent in the aggregate or that Landlord is furnishing the same services to other tenants, at all, on the same level or on the same basis, or any warranty or any statement of Landlord which is not set forth herein or in one or more of the exhibits attached hereto.

29.13 Landlord Exculpation. The liability of Landlord or the Landlord Parties to Tenant for any default by Landlord under this Lease or arising in connection herewith or with Landlord’s operation, management, leasing, repair, renovation, alteration or any other matter relating to the Project or the Premises shall be limited solely and exclusively to an amount which is equal to the interest of Landlord in the Building including any sales or insurance proceeds received by Landlord or the Landlord Parties in connection with the Project, Building or Premises. Neither Landlord, nor any of the Landlord Parties shall have any personal liability therefor, and Tenant hereby expressly waives and releases such personal liability on behalf of itself and all persons claiming by, through or under Tenant. The limitations of liability contained in this Section 29.13 shall inure to the benefit of Landlord’s and the Landlord Parties’ present and future partners, beneficiaries, officers, directors, trustees, shareholders, agents and employees, and their respective partners, heirs, successors and assigns. Under no circumstances shall any present or future partner of Landlord (if Landlord is a partnership), or trustee or beneficiary (if Landlord or any partner of Landlord is a trust), have any liability for the performance of Landlord’s obligations under this Lease. Notwithstanding any contrary provision herein, neither Landlord nor the Landlord Parties shall be liable under any circumstances for injury or damage to, or interference with, Tenant’s business, including but not limited to, loss of profits, loss of rents or other revenues, loss of business opportunity, loss of goodwill or loss of use, or any other consequential damages, in each case, however occurring, or loss to inventory, scientific research, scientific experiments, laboratory animals, products, specimens, samples, and/or scientific, business, accounting and other records of every kind and description kept at the premises and any and all income derived or derivable therefrom. Similarly, except with respect to Tenant’s violations of the provisions of this Lease regarding Hazardous Materials and Tenant’s holding over in the Premises following the expiration or sooner termination of this Lease as set forth in Article 16, Tenant shall not be liable under any circumstances for injury or damage to, or interference with, Landlord’s business, including loss of profits or other revenues (not including, however, loss of rents), loss of business opportunity, loss of goodwill or loss of use or any other consequential damages, in each case, however occurring. Except to the extent provided by Applicable Law (e.g., piercing the corporate veil), under no circumstances shall any present or future partner, member, stockholder, trustee, beneficiary, officer, director, employee or agent of Tenant or the Tenant Parties have any personal liability for the performance of Tenant’s obligations under this Lease.

29.14 Entire Agreement. It is understood and acknowledged that there are no oral agreements between the parties hereto affecting this Lease and this Lease constitutes the parties’ entire agreement with respect to the leasing of the Premises and supersedes and cancels any and all previous negotiations, arrangements, brochures, agreements and understandings, if any, between the parties hereto or displayed by Landlord to Tenant with respect to the subject matter thereof, and none thereof shall be used to interpret or construe this Lease. None of the terms, covenants, conditions or provisions of this Lease can be modified, deleted or added to except in writing signed by the parties hereto.

29.15 Right to Lease. Landlord reserves the absolute right to effect such other tenancies in the Project as Landlord in the exercise of its sole business judgment shall determine to best promote the interests of the Building or Project.

29.16 Force Majeure. Any prevention, delay or stoppage due to strikes, lockouts, labor disputes, acts of God, acts of war, terrorist acts, inability to obtain services, labor, or materials or reasonable substitutes therefor, governmental actions, civil commotions, fire or other casualty, and other causes beyond the reasonable control of the party obligated to perform, except with respect to the obligations imposed with regard to Rent and other charges to be paid pursuant to this Lease (collectively, a “Force Majeure”), notwithstanding anything to the contrary contained in this Lease, shall excuse the performance of such party for a period equal to any such prevention, delay or stoppage and, therefore, if this Lease specifies a time period for performance of an obligation of either party, that time period shall be extended by the period of any delay in such party’s performance caused by a Force Majeure.

29.17 Waiver of Redemption by Tenant. Tenant hereby waives, for Tenant and for all those claiming under Tenant, any and all rights now or hereafter existing to redeem by order or judgment of any court or by any legal process or writ, Tenant’s right of occupancy of the Premises after any termination of this Lease.

2. Plans and Construction. Landlord and Tenant shall comply with the procedures set forth in this Paragraph 2 in preparing, delivering and approving matters relating to the Tenant Improvements.

(a) Approved Plans and Working Drawings for Tenant Improvements. Tenant shall promptly and diligently work with the Architect to cause to be prepared and delivered to Landlord for approval (which approval shall not be unreasonably withheld, conditioned or delayed by Landlord) proposed schematic plans and outline specifications for the Tenant Improvements. Following mutual approval of such proposed schematic plans and outline specifications by Landlord and by Tenant (as so approved, the “Approved Schematic Plans”), Tenant shall then work with the Architect to cause to be prepared, promptly and diligently (assuming timely delivery by Landlord of any information and decisions required to be furnished or made by Landlord in order to permit preparation of final working drawings, all of which information and decisions Landlord will deliver promptly and with reasonable diligence), and delivered to Landlord for approval (which approval shall not be unreasonably withheld, conditioned or delayed by Landlord) final detailed working drawings and specifications for the Tenant Improvements, including (without limitation) any applicable life safety, mechanical, electrical and plumbing working drawings and final architectural drawings (collectively, “Final TI Working Drawings”), which Final TI Working Drawings shall substantially conform to the Approved Schematic Plans. Upon receipt from Tenant of proposed schematic plans and outline specifications, proposed Final TI Working Drawings, any other plans and specifications, or any revisions or resubmittals of any of the foregoing, as applicable, Landlord shall promptly and diligently (and in all events within 10 days after receipt in the case of an initial submittal of schematic plans and outline specifications or proposed Final TI Working Drawings, and within 7 days after receipt in the case of any other plans and specifications or any revisions or resubmittals of any of the foregoing) either approve such proposed schematic plans and outline specifications or proposed Final TI Working Drawings, as applicable, or set forth in writing with particularity any changes necessary to bring the aspects of such proposed schematic plans and outline specifications or proposed Final TI Working Drawings into a form which will be reasonably acceptable to Landlord. Upon approval of the Final TI Working Drawings by Landlord and Tenant, the Final TI Working Drawings shall constitute the “Approved TI Plans,” superseding (to the extent of any inconsistencies) any inconsistent features of the previously existing Approved Schematic Plans.

(b) Cost of Improvements. “Cost of Improvement” shall mean, with respect to any item or component of the Tenant Improvements for which a cost must be determined in order to allocate such cost, or an increase in such cost, to Tenant pursuant to this Tenant Work Letter, the sum of the following (unless otherwise agreed in writing by Landlord and Tenant with respect to any specific item or component or any category of items or components): (i) all sums paid to contractors or subcontractors for labor and materials furnished in connection with construction of such item or component; (ii) all costs, expenses, payments, fees and charges (other than penalties) paid to or at the direction of any city, county or other governmental or quasi-governmental authority or agency which are required to be paid in order to obtain all necessary governmental permits, licenses, inspections and approvals relating to construction of such item or component; (iii) engineering and architectural fees for services rendered in connection with the design and construction of such item or component (including, but not limited to, the TI Architect for such item or component and an electrical engineer, mechanical engineer and civil engineer, if applicable); (iv) sales and use taxes actually charged and incurred; (v) testing and inspection costs; (vi) the cost of power, water and other utility facilities and the cost of collection and removal of debris required in connection with construction of such item or component; (vii) costs incurred for builder’s risk softinsurance; and (viii) all other “hard” and “” costs incurred in the construction of such item or component in accordance with the Approved TI Plans (if applicable) and this Tenant Work Letter; provided that the Cost of Improvements shall not include any internal or third-party costs incurred by Landlord.

(c) Construction of Landlord’s TI Work. Following completion of the Approved TI Plans, Landlord shall apply for and use diligent efforts to obtain the necessary permits and approvals to allow construction of all Tenant Improvements. Upon receipt of such permits and approvals, Landlord shall, at Tenant’s expense (subject to Landlord’s payment of the Tenant Improvement Allowance), promptly and diligently construct and complete the Tenant Improvements substantially in accordance with the Approved TI Plans, subject to Unavoidable Delays and Tenant Delays (if any). Such construction shall be performed in a neat, good and workmanlike manner and shall materially conform to all Applicable Laws, rules, regulations, codes, ordinances, requirements, covenants, conditions and restrictions applicable thereto in force at the time such work is completed.

(d) Changes.

(i) If Landlord determines at any time that changes in the Final TI Working Drawings or in any other aspect of the Approved TI Plans relating to any item of Landlord’s TI Work are required as a result of Applicable Law or governmental requirements, or are required at the insistence of any other third party whose approval may be required with respect to the Tenant Improvements, or are required as a result of unanticipated conditions encountered in the course of construction, then Landlord shall promptly (A) advise Tenant of such circumstances and (B) at Tenant’s sole cost and expense, subject to Landlord’s payment of the Tenant Improvement Allowance, cause revised Final TI Working Drawings to be prepared by the Architect and submitted to Tenant, for Tenant’s information.

[Britannia Gateway Business Park]

[Senti Biosciences, Inc.]

(ii) If Tenant at any time desires any changes, alterations or additions to the Final TI Working Drawings, Tenant shall submit a detailed written request to Landlord specifying such changes, alterations or additions (a “Tenant Change Request”). Upon receipt of any such request, Landlord shall promptly notify Tenant of (A) whether the matters proposed in the Tenant Change Request are approved by Landlord (which approval shall not be unreasonably withheld, conditioned or delayed by Landlord), (B) Landlord’s estimate of the number of days of delay, if any, which shall be caused in the construction of the Tenant Improvements by such Tenant Change Request if implemented (including, without limitation, delays due to the need to obtain any revised plans or drawings and any governmental approvals), and (C) Landlord’s estimate of the increase, if any, which shall occur in the cost of construction of the Tenant Improvements affected by such Tenant Change Request if such Tenant Change Request is implemented (including, but not limited to, any costs of compliance with laws or governmental regulations that become applicable because of the implementation of the Tenant Change Request). If Landlord approves the Tenant Change Request and Tenant notifies Landlord in writing, within three (3) business days after receipt of such notice from Landlord, of Tenant’s approval of the Tenant Change Request (including the estimated delays and cost increases, if any, described in Landlord’s notice), then Landlord shall promptly cause such Tenant Change Request to be implemented and Tenant shall be responsible for all actual costs or cost increases resulting from or attributable to the implementation of the Tenant Change Request, and any actual delays resulting therefrom shall be deemed to be a Tenant Delay (subject to Landlord’s payment of the Tenant Improvement Allowance). If Tenant fails to notify Landlord in writing of Tenant’s approval of such Tenant Change Request within said three (3) business day period, then such Tenant Change Request shall be deemed to be withdrawn and shall be of no further effect.

(iii) Project Management. Unless and until revoked by Landlord by written notice delivered to Tenant, Landlord hereby (i) delegates to Project Manager the authority to exercise all approval rights, supervisory rights and other rights or powers of Landlord under this Tenant Work Letter with respect to the design and construction of the Tenant Improvements, and (ii) requests that Tenant work with Project Manager with respect to any logistical or other coordination matters arising in the course of construction of the Tenant Improvements, including monitoring Tenant’s compliance with its obligations under this Tenant Work Letter and under the Lease with respect to the design and construction of the Tenant Improvements. Tenant acknowledges the foregoing delegation and request, and agrees to cooperate reasonably with Project Manager as Landlord’s representative pursuant to such delegation and request. Fees and charges of Project Manager for such services shall be at Tenant’s sole expense, subject to Landlord’s payment of the Tenant Improvement Allowance. Such fees shall equal the sum of (X) the product of (A) 2.65% and (B) the amount of the Tenant Improvement Allowance and Additional TI Allowance which Tenant elects to utilize, and (Y) the product of (C) 2.0% and (D) the amount of Tenant Funds Amount which Tenant elects to utilize.

3. Completion.

(a) When Landlord receives written certification from Architect that construction of the Tenant Improvements in the Building has been completed in accordance with the Approved TI Plans (except for Punch List Work), Landlord shall prepare and deliver to Tenant a certificate signed by both Landlord and Architect (the “Substantial Completion Certificate”) (i) certifying that the construction of the Tenant Improvements has been substantially completed in a good and workmanlike manner in accordance with the Approved TI Plans in all material respects, subject only to completion of Punch List Work, and specifying the date of that completion, and (ii) certifying that the Tenant Improvements comply in all material respects with all laws, rules, regulations, codes, ordinances, requirements, covenants, conditions and restrictions applicable thereto at the time of such delivery. Upon receipt by Tenant of the Substantial Completion Certificate and tender of possession of the Lease Commencement Premises by Landlord to Tenant, and receipt of any certificate of occupancy or its legal equivalent, or other required sign-offs from any applicable governmental authority, allowing the legal occupancy of the Lease Commencement Premises, the Tenant Improvements will be deemed delivered to Tenant and “Ready for Occupancy” for all purposes of the Lease (subject to Landlord’s continuing obligations with respect to any Punch List Work, to construct any Tenant Improvements in the Early Occupancy Premises and to any other express obligations of Landlord under the Lease or this Tenant Work Letter with respect to such Tenant Improvements).

[Britannia Gateway Business Park]

[Senti Biosciences, Inc.]

(b) Promptly following delivery of the Substantial Completion Certificate for the Tenant Improvements in the Building, Project Manager or other representatives of Landlord shall conduct one or more “walkthroughs” of the Building with Tenant and Tenant’s representatives, to identify any items of Punch List Work that may require correction and to prepare a joint punch list reflecting any such items, following which Landlord shall diligently complete the Punch List Work reflected in such joint punch list. At any time within thirty (30) days after delivery of such Substantial Completion Certificate, Tenant shall be entitled to submit one or more lists to Landlord supplementing such joint punch list by specifying any additional items of Punch List Work to be performed on the applicable Tenant Improvements, and upon receipt of such list(s), Landlord shall diligently complete such additional Punch List Work. Promptly after Landlord provides Tenant with the Substantial Completion Certificate and completes all applicable Punch List Work for the Building, Landlord shall cause the recordation of a Notice of Completion (as defined in the California Civil Code) with respect to the Tenant Improvements.

(c) All construction, product and equipment warranties and guaranties obtained by Landlord with respect to the Tenant Improvements shall, to the extent reasonably obtainable, include a provision that such warranties and guaranties shall also run to the benefit of Tenant, and Landlord shall cooperate with Tenant in a commercially reasonable manner to assist in enforcing all such warranties and guaranties for the benefit of Tenant.

(d) Notwithstanding any other provisions of this Tenant Work Letter or of the Lease, but subject to Section (1)(j) above, if Landlord is delayed in substantially completing any of the Tenant Improvements as a result of any Tenant Delay, then the Premises shall be deemed to have been Ready for Occupancy on the date the Premises would have been Ready for Occupancy absent such Tenant Delay, measured on a day for day basis.

4. Payment of Costs.

(a) Tenant Improvement Allowance. Subject to any restrictions, conditions or limitations expressly set forth in this Tenant Work Letter or in the Lease or as otherwise expressly provided by mutual written agreement of Landlord and Tenant, Cost of Improvement shall be paid or reimbursed by Landlord up to a maximum amount equal to $6,365,816.00 (i.e., $164.00 per rentable square foot of the Premises) (the “Tenant Improvement Allowance”), which amount is being made available by Landlord to be applied towards the Cost of Improvement, less any reduction in or charge against such amount pursuant to any applicable provisions of the Lease or of this Tenant Work Letter. Tenant shall be responsible, at its sole cost and expense, for payment of the entire Cost of Improvement in excess of the Tenant Improvement Allowance (and the Additional Tenant Improvement Allowance as provided below), including (but not limited to) any costs or cost increases incurred as a result of Tenant Delays (unless caused by Landlord), governmental requirements or unanticipated conditions (unless caused by Landlord), and for payment of any and all costs and expenses relating to any alterations, additions, improvements, furniture, furnishings, equipment, fixtures and personal property items which are not eligible for application of Tenant Improvement Allowance funds under the restrictions expressly set forth below in this paragraph, but Tenant shall be entitled to use or apply the entire Tenant Improvement Allowance toward the Cost of Improvements (subject to any applicable restrictions, conditions, limitations, reductions or charges set forth in the Lease or in this Tenant Work Letter) prior to being required to expend any of Tenant’s own funds for the Tenant Improvements. The funding of the Tenant Improvement Allowance shall be made on a monthly basis or at other convenient intervals mutually approved by Landlord and Tenant and in all other respects shall be based on such commercially reasonable disbursement conditions and procedures as Landlord, Project Manager and Landlord’s lender (if any) may reasonably prescribe. Notwithstanding the foregoing provisions, (i) under no circumstances shall the Tenant Improvement Allowance or any portion thereof be used or useable by Tenant for any moving or relocation expenses of Tenant, or for any Cost of Improvement (or any other cost or expense) associated with any moveable furniture or trade fixtures, personal property or any other item or element which, under the applicable provisions of the Lease, will not become Landlord’s property and remain with the Building upon expiration or termination of the Lease, and (ii) except as otherwise expressly provided in this Tenant Work Letter or expressly approved by Landlord in writing, any portion of the Tenant Improvement Allowance which has not been claimed or drawn by Tenant prior to December 31, 2019 (as extended by force majeure or delays caused by Landlord), shall expire and shall no longer be available to Tenant thereafter. Notwithstanding anything to the contrary herein, the Tenant Improvements shall not include (and Landlord shall be solely responsible for and the Tenant Improvement Allowance shall not be used for) the following: (a) costs incurred due to the presence of any Hazardous Materials in the Premises, if any, but with respect to removal and remediation of any such Hazardous Materials, only to the extent such removal or remediation is required by Applicable Laws enforced as of the date of this Lease for improvements in the Premises generally (as opposed to the specific Tenant Improvements) and to the extent the same required in order to allow Tenant to obtain a certificate of occupancy or its legal equivalent, for the Premises for the Permitted Use assuming a normal and customary occupancy density; and (b) wages, labor and overhead for overtime and premium time unless approved by Tenant (which approval shall not be unreasonably withheld, conditioned or delayed).

[Senti Biosciences, Inc.]

(b) Additional TI Allowance. In addition to the Tenant Improvement Allowance, Tenant shall have the right, by written notice to Landlord given on or before the Lease Commencement Date, to use up to $30.00 per RSF of the Premises (i.e., up to $1,160,820.00) (the “Additional TI Allowance”) towards the payment of the costs of the Tenant Improvement Allowance Items. In the event Tenant exercises its right to use all or any portion of the Additional TI Allowance, Tenant shall be required to pay Landlord, commencing on the date the Tenant Improvements are completed (the “Additional Payment Commencement Date”), the “Additional TI Allowance Payment,” as that term is defined below, in consideration of Landlord provision of the Additional TI Allowance. The “Additional TI Allowance Payment” shall be determined as the missing component of an annuity, which annuity shall have (i) the amount of the Additional TI Allowance utilized by Tenant as the present value amount, (ii) a number equal to the number of full calendar months then remaining in the Lease Term as the number of payments, (iii) a monthly interest factor equal to eighty-three one-hundredths percent (0.83%), which is equal to ten percent (10%) divided by twelve (12) months per year, and (iv) the Additional TI Allowance Payment as the missing component of the annuity. Following the calculation of the Additional TI Allowance Payment, Landlord and Tenant will enter into a lease amendment to confirm the amount thereof. Any portion of the Additional TI Allowance which has not been claimed or drawn by Tenant prior to December 31, 2019 (as extended by force majeure or delays caused by Landlord), shall expire and shall no longer be available to Tenant thereafter.

(c) Tenant Funds. For additional funds required to complete the cost of the work, that are in excess of, or elected by the Tenant to be used in place of the Tenant Improvement Allowance, and the Additional TI Allowance, these shall be considered “Tenant Funds.” The total cost to construct the Tenant Improvements as managed by Landlord and the Project Manager under this Work Letter shall be the “Project Budget.” Landlord shall present the Project Budget to Tenant for Tenant’s review, and in the event the Tenant Funds amount is a material amount, Landlord and Tenant shall use prompt, good faith efforts to revise or “value engineer” the Approved Plans so as to reduce the Project Budget to an amount reasonably acceptable to Tenant, and any delay resulting from such value engineering shall be deemed a Tenant Delay. The Landlord understands that at the time of the agreed upon Guaranteed Maximum Price (GMP), the Tenant Funds amount is an estimate and exact costs will not be known until project closeout. The Tenant is required, at the time of agreement of the GMP, to provide a purchase order to the Landlord for the full estimated amount of the Tenant Funds, provided that Tenant shall not be required to make payment, if any, until the close out of the project and a true up of costs are provided to Tenant. In the event the Tenant Funds at project closeout are less than the amount agreed upon within the Project Budget, the Landlord will only bill the Tenant for the Tenant Funds that have been utilized. In the event the Tenant Funds exceed the amount agreed upon within the Project Budget, through added scope changes, the Tenant shall provide additional purchases orders to the Landlord, which will be included in the Tenant Change Request process that the Landlord’s representative administers.

5. No Agency. Nothing contained in this Tenant Work Letter shall make or constitute Tenant as the agent of Landlord.

6. Miscellaneous. All references in this Tenant Work Letter to a number of days shall be construed to refer to calendar days, unless otherwise specified herein. In all instances where Landlord’s or Tenant’s approval is required, if no written notice of disapproval is given within the applicable time period, at the end of that period Landlord or Tenant shall be deemed to have given approval (unless the provision requiring Landlord’s or Tenant’s approval expressly states that non-response is deemed to be a disapproval or withdrawal of the pending action or request, in which event such express statement shall be controlling over the general statement set forth in this sentence) and the next succeeding time period shall commence. If any item requiring approval is disapproved by Landlord or Tenant (as applicable) in a timely manner, the procedure for preparation of that item and approval shall be repeated.

7. Restoration. Landlord shall make its determination with respect to removal or restoration of any portion of the Tenant Improvements constructed in the Premises pursuant to the terms of this Tenant Work Letter upon the termination of the Lease at the time of Landlord’s review of the Final TI Working Drawings. In connection with the foregoing, Landlord hereby acknowledges and agrees that the Tenant Improvements shown on the preliminary plan attached to this Tenant Work Letter as Schedule 2 shall not be subject to removal, and to the extent that the Approved Schematic Plans, the Final TI Working Drawings and the Tenant Improvements are materially consistent with and a logical extension of such preliminary plan, the Tenant Improvements shall not be subject to removal.

8. Time Deadlines. Tenant shall use commercially reasonable, good faith, efforts and all due diligence to cooperate with the Architect, General Contractor and Landlord to complete all phases of the construction drawings set forth in this Tenant Work Letter and the permitting process and to receive the permits as soon as possible after the execution of the. The applicable dates for approval of items, plans and drawings as described in this Tenant Work Letter are set forth and further elaborated upon in Schedule 1 to this Exhibit B attached hereto (the “Time Deadlines”), attached hereto. Tenant agrees to utilize commercially reasonable efforts to comply with the Time Deadlines.

9. Occupancy During Construction; No Constructive Eviction. Tenant hereby acknowledges and agrees that (i) Tenant shall be in occupancy of the Early Occupancy Premises during the construction of the Tenant Improvements in the Lease Commencement Premises, (ii) Tenant shall be in occupancy of the entire Premises during the construction of the Tenant Improvements in the Early Occupancy Premises, and (iii) the Tenant Improvements in the Early Occupancy Premises shall not be performed prior to the Lease Commencement Date (but rather shall be performed by Landlord during the Lease Term).

Britannia Biotech Gateway Business Park

[Britannia Gateway Business Park]

[Senti Biosciences, Inc.]

☐ Yes ☐ No ☐ No, but one will be prepared and submitted to the Landlord property management company.

If so, please attach a copy of this permit or provide it later when it has been prepared.

7.2

Has a Hazardous Materials Business Plan (HMBP) been developed for the site and submitted via the State of California Electronic Reporting System (CERS)? [NOTE: The trigger limits for having to do this are > 200 cubic feet if any one type of compressed gas(except for carbon dioxide and inert simple asphyxiant gases, which have a higher trigger limit of > 1,000 cubic feet); > 55 gallons if any one type of hazardous chemical liquid; and >500 pounds of any one type of hazardous chemical solid. So a full-sixe gas cylinder and a 260-liter of liquid nitrogen are triggers! Don’t forget the diesel fuel in a backup emergency generator if the diesel tank size is > 55 gallons and it is permitted under the tenant (rather than under the landlord).] NOTE: Each local Certified Unified Program Agency (CUPA) in California governs the HMBP process so start there. Examples: the CUPA for cities in San Mateo County is the County Environmental Health Department; the CUPA for the City of Hayward, CA is the Hayward Fire Department; the CUPA for Mountain View is the Mountain View Fire Department; and, the CUPA for San Diego is the County of San Diego Hazardous Materials Division (HMD),

☐ Yes ☐ No, not required. ☐ No, but one will be prepared and submitted, and a copy will be provided to the landlord property management company.

If one has been completed, please attach a copy. Continue to provide updated versions as they are completed. This is a legal requirement in that State law requires that the owner/operator of a business located on leased or rented real property shall notify, in writing, the owner of the property that the business is subject to and is in compliance with the Hazardous Materials Business Plan requirements (Health and Safety Code Chapter 6.95 Section 25505.1).

7.3

NOTE: Please be advised that if you are involved in any tenant improvements that require a construction permit, you will be asked to provide the local city with a Hazardous Materials Inventory Statement (HMIS) to ensure that your hazardous chemicals fall within the applicable Fire Code fire control area limits for the applicable construction occupancy of the particular building. The HMIS will include much of the information listed in Section 2-2. Neither the landlord nor the landlord’s property management company expressly warrants that the inventory provided in Section 2-2 will necessarily meet the applicable California Fire Code fire control area limits for building occupancy, especially in shared tenant occupancy situations. It is the responsibility of the tenant to ensure that a facility and site can legally handle the intended operations and hazardous materials desired/ needed for its operations, but the landlord is happy to assist in this determination when possible.

CERTIFICATION

I am familiar with the real property described in this questionnaire. By signing below, I represent and warrant that the answers to the above questions are complete and accurate to the best of my knowledge. I also understand that Lessor will rely on the completeness and accuracy of my answers in assessing any environmental liability risks associated with the property.

Exhibit 10.11

FIRST AMENDMENT TO LEASE

This FIRST AMENDMENT TO LEASE (“Amendment”) is made and entered into as of May 8, 2019, by and between BRITANNIA BIOTECH GATEWAY LIMITED PARTNERSHIP, a Delaware limited partnership (“Landlord”), and SENTI BIOSCIENCES, INC., a Delaware corporation (“Tenant”).

R E C I T A L S :

A. Landlord and Tenant are parties to that certain Office Lease dated July 17, 2018 (the “Lease”), pursuant to which Landlord leases to Tenant and Tenant leases from Landlord that certain 38,694 rentable square feet of space (the “Premises”) located on the first (1st) floor of that certain building located at Two Corporate Drive, South San Francisco, California (the “Building”).

B. Landlord and Tenant desire to amend the Lease on the terms and conditions set forth in this Amendment.

A G R E E M E N T :

NOW, THEREFORE, in consideration of the foregoing recitals and the mutual covenants contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

1. Terms. All capitalized terms when used herein shall have the same respective meanings as are given such terms in the Lease unless expressly provided otherwise in this Amendment.

2. Additional TI Allowance. Pursuant to the terms of Section 4(b) of the Tenant Work Letter attached to the Lease, in addition to the Tenant Improvement Allowance, Tenant is entitled to utilize up to $30.00 per RSF of the Premises (i.e., up to $1,160,820.00) (the “Additional TI Allowance”) towards the payment of the costs of the Cost of Improvements, by delivering a written notice to Landlord prior to the Lease Commencement Date. Landlord and Tenant hereby acknowledge and agree that Tenant hereby timely elects to utilize $500,000.00 of the Additional TI Allowance (the “Utilized Additional TI Allowance”); provided, however, Landlord hereby acknowledges that Tenant retains the right to utilize the remaining portion of the Additional TI Allowance if Tenant so elects pursuant to the terms of the Lease. In connection with the foregoing, in the first sentence of Section 4(b) of the Work Letter, the reference to “Tenant Improvement Allowance Items” shall be replaced with “the Cost of Improvement” as defined in Section 2(c) of the Work Letter.

- 1 -

3. Repayment of Utilized Additional TI Allowance. Pursuant to the terms of Section 4(b) of the Tenant Work Letter attached to the Lease, in the event Tenant exercises its right to use all or any portion of the Additional TI Allowance, Tenant shall be required to pay Landlord the Additional TI Allowance Payment. Notwithstanding the foregoing or any provision to the contrary contained in the Lease, Landlord hereby grants Tenant the option to elect to repay the Utilized Additional TI Allowance either (i) in one lump sum pursuant to the terms hereof, or (ii) in monthly payments pursuant to the terms of Section 4(b) of the Lease (along with any other portion of the Additional TI Allowance which Tenant elects to use), which election shall be made by delivering written notice to Landlord on or before October 31, 2019. Tenant’s failure to timely send such notice shall be deemed Tenant’s election to repay the Utilized Additional TI Allowance in monthly payments. In the event Tenant elects (or is deemed to have elected) to repay the Utilized Additional TI Allowance in monthly payments, then such monthly payments shall be determined in accordance with the terms of Section 4(b) of the Tenant Work Letter along with any other portion of the Additional TI Allowance which Tenant elects to utilize. In the event Tenant timely elects to repay the Utilized Additional TI Allowance in one lump sum payment, then Tenant hereby agrees to deliver to Landlord, on or before December 31, 2019, the amount of $$533,333.33 as the repayment of the Additional TI Allowance (with interest calculated as set forth in the Lease).

4. California Accessibility Disclosure. For purposes of Section 1938 of the California Civil Code, Landlord hereby discloses to Tenant, and Tenant hereby acknowledges that the Common Areas and the Premises have not undergone inspection by a Certified Access Specialist (CASp).

5. No Broker. Landlord and Tenant hereby warrant to each other that they have had no dealings with any real estate broker or agent in connection with the negotiation of this Amendment, and that they know of no real estate broker or agent who is entitled to a commission in connection with this Amendment. Each party agrees to indemnify and defend the other party against and hold the other party harmless from any and all claims, demands, losses, liabilities, lawsuits, judgments, costs and expenses (including without limitation reasonable attorneys’ fees) with respect to any leasing commission or equivalent compensation alleged to be owing on account of any dealings with any real estate broker or agent, occurring by, through, or under the indemnifying party. The terms of this Section 5 shall survive the expiration or earlier termination of the term of the Lease, as hereby amended.

6. No Further Modification. Except as specifically set forth in this Amendment, all of the terms and provisions of the Lease shall remain unmodified and in full force and effect.

Exhibit 10.12

SECOND AMENDMENT TO LEASE

This SECOND AMENDMENT TO LEASE (“Amendment”) is made and entered into as of June 17, 2020, by and between BRITANNIA BIOTECH GATEWAY LIMITED PARTNERSHIP, a Delaware limited partnership (“Landlord”), and SENTI BIOSCIENCES, INC., a Delaware corporation (“Tenant”).

R E C I T A L S :

A. Landlord and Tenant are parties to that certain Office Lease dated July 17, 2018 (the “Original Lease”), pursuant to which Landlord leases to Tenant and Tenant leases from Landlord that certain 38,694 rentable square feet of space (the “Premises”) located on the first (1st) floor of that certain building located at Two Corporate Drive, South San Francisco, California (the “Building”). The Original Lease, as amended by the First Amendment to Lease dated May 8, 2019, and by this Amendment, is referred to collectively as the “Lease”.

B. Tenant has failed to pay Base Rent and Additional Rent due under the Lease prior to May 1, 2020, in the amount of $379,859.31 (the “Past Due Rent”).

C. Landlord is currently holding the Irrevocable Standby Letter of Credit No. SVBSF013017 in the amount of $497,218.70, delivered by Tenant to Landlord in accordance with the terms of the Lease (the “Letter of Credit”).

D. Landlord and Tenant presently desire to enter into this Amendment to provide for the payment of a portion of the Past Due Rent, and to defer payment of additional amounts of Rent due under the Lease, due to the COVID-19 situation, on the terms and conditions set forth below.

A G R E E M E N T :

1. Terms. All capitalized terms when used herein shall have the same respective meanings as are given such terms in the Lease unless expressly provided otherwise in this Amendment.

2. Payment of April Rent. Concurrently with Tenant’s execution of this Amendment, Tenant shall pay the Base Rent and Tenant’s Share of Direct Expenses to Landlord for April, 2020, in the amount of $264,462.32. Upon such payment, the Past Due Rent will be reduced to equal $115,396.99. Landlord acknowledges that such $115,396.99 is based on the recent reconciliation of Direct Expenses due under the Lease, and remains subject to review and agreement by Tenant and Tenant’s right to review and audit such amounts as provided in Section 4.6 of the Lease.


		–1–

3. Temporary Deferral of Rent. Tenant’s obligation to pay the remaining Past Due Rent, as well as the Base Rent and Tenant’s Share of Direct Expenses owed for May, 2020 ($264,462.32), and June, 2020 ($264,462.32), shall be deferred, and repaid as further set forth in this Second Amendment. The total of such deferred amounts, i.e., $644,321.63 (subject to adjustment as provided in Section 2, above), is referred to herein as the “Rent Deferral Amount”. Tenant acknowledges that federal, state and local governmental authorities (including, without limitation, the United States, State of California, County of San Mateo and City of South San Francisco) may have issued orders or enacted statutes that provide certain protections to commercial tenants who can prove they are unable to pay rent due to circumstances related to the COVID-19 virus. Tenant (i) enters into this Second Amendment voluntarily and with full knowledge of those protections and (ii) acknowledges that it is waiving those protections in favor of the terms set forth herein.

4. July Rent. Tenant shall pay Rent due under the Lease for July, 2020, and all months thereafter, in accordance with the terms of the Lease.

5. Repayment of Rent Deferral Amount. Tenant shall repay the Rent Deferral Amount to Landlord, in full, on or before the earlier of (i) the date that is fifteen (15) days after any “Funding Event”, as defined in Section 8, below, and (ii) November 30, 2020.

6. Draw of Letter of Credit; Application of Funds. Notwithstanding the terms of Section 5, above, Tenant agrees that (i) if Tenant has not repaid the Rent Deferral Amount to Landlord in full on or before November 30, 2020, or (ii) if an Acceleration Event, as defined below, has occurred, then in either such case Landlord shall have the irrevocable, absolute, and immediate right to: (a) draw down the Letter of Credit in full; and (b) irrevocably retain and apply any cash proceeds Landlord receives on account of such draw(s) to the Rent Deferral Amount or other amounts due under the Lease. Such application of the Letter of Credit shall reduce the outstanding Rent Deferral Amount to $147,102.93. The Lease is hereby amended to provide that the full amount of the Letter of Credit shall be immediately due and owing by Tenant to Landlord as set forth above, and that in such event Landlord shall have the right to immediately thereafter draw on the Letter of Credit in full. Tenant hereby: (i) waives any rights it may have to object to any draw(s) on the Letter of Credit, agrees to fully cooperate with Landlord in connection with any draw(s) on the Letter of Credit, and agrees to execute any documents requested by either Landlord or Silicon Valley Bank in connection with such draw(s); and (ii) agrees and acknowledges that Landlord may, in connection with any such draw(s) on the Letter of Credit, provide the following certification to Silicon Valley Bank and that such certification is true and accurate:


		–2–

THE UNDERSIGNED HEREBY CERTIFIES THAT THE LANDLORD , EITHER (A) UNDER THE LEASE (DEFINED BELOW), OR (B) AS A RESULT OF THE TERMINATION OF SUCH LEASE, HAS THE RIGHT TO DRAW DOWN THE AMOUNT OF USD $497,218.70 IN ACCORDANCE WITH THE TERMS OF THAT CERTAIN OFFICE LEASE DATED JULY 17, 2018, AS THE SAME MAY HAVE BEEN AMENDED FROM TIME TO TIME (COLLECTIVELY, THE “LEASE”), OR SUCH AMOUNT CONSTITUTES DAMAGES OWING BY THE TENANT TO BENEFICIARY RESULTING FROM THE BREACH OF SUCH LEASE BY THE TENANT THEREUNDER, OR THE TERMINATION OF SUCH LEASE, AND SUCH AMOUNT REMAINS UNPAID AT THE TIME OF THIS DRAWING.

7. Default by Tenant. Notwithstanding any contrary provision of the Lease, as amended hereby, but subject to applicable law, Landlord shall have the right, at its option, to accelerate the repayment of the Rent Deferral Amount, and interest thereon, and to make the same immediately due and payable in full by Tenant (with interest at the rate provided in Article 25 of the Lease, which interest shall accrue monthly from and after the calendar month in which each installment of the Rent Deferral Amount was originally due and owing under the Lease) and to make the same immediately due and payable in full by Tenant (the “Accelerated Amount”), upon the occurrence of any of the following (each, an “Acceleration Event”): (i) any breach of the representations, warranties, certifications and covenants of Tenant set forth in this Second Amendment beyond applicable notice and cure periods; (ii) any default by Tenant under the Lease, as amended hereby, beyond applicable notice and cure periods; (iii) any assignment or attempted assignment of the Lease to any third party in violation of Article 14 of the Lease; (iv) a general assignment by Tenant or any guarantor of the Lease for the benefit of creditors, or the taking of any corporate action in furtherance of bankruptcy or dissolution (whether or not there exists any proceeding under an insolvency or bankruptcy law), or the filing by or against Tenant or any guarantor of any proceeding under an insolvency or bankruptcy law; or (v) the rejection, or deemed rejection, of the Lease, as amended hereby, in any insolvency or bankruptcy case or proceeding. Further, notwithstanding any contrary provision of the Lease, as amended hereby, the Rent Deferral Amount, and interest thereon as provided above, payable hereunder shall constitute a part of the Rent payable by Tenant under the Lease. Landlord may include in any unpaid sums or amounts it seeks to recover from Tenant the aggregate Rent Deferral Amount, it being agreed by Tenant that the Rent Deferral Amount has been granted by Landlord in consideration of Tenant not defaulting under the terms and conditions of the Lease. Tenant agrees that Landlord may include the Accelerated Amount in any statutory notices (or notices required under the Lease), that Landlord is required to give Tenant as a condition precedent to an action for recovery of possession of the Existing Premises.

8. Result of a Draw; Replenishment of Letter of Credit. Notwithstanding the terms of the Lease to the contrary, following the draw upon the Letter of Credit by Landlord as set forth in Section 6, above, if an Acceleration Event has not occurred, then Tenant shall not have the obligation to deliver a replacement Letter of Credit until the later of (i) the date that is fifteen (15) days after the occurrence of a “Funding Event” as defined below, or (ii) November 30, 2020 (the “Letter of Credit Replacement Date”). On or before the Letter of Credit Replacement Date, or immediately following any draw of the Letter of Credit due to an Acceleration Event, Tenant shall provide Landlord with a new “L-C” as defined in Section 21.1 of the Original Lease, in the “L-C Amount” as defined in Section 21.1 of the Original Lease (i.e., $497,218.70). Such new L-C shall comply with and be subject to all of the terms and conditions of Article 21 of the Original Lease. Tenant’s failure to provide such new L-C on or before the Letter of Credit Replacement Date shall be a material event of default under the Lease, which shall immediately entitle Landlord to pursue all of its remedies at law, in equity or under the Lease in connection therewith. As used herein a “Funding Event” shall mean Tenant’s receipt of new loan amounts or equity funding after the date hereof that total, in the aggregate, $5,000,000.00 or more.


		–3–

9. Confidentiality. Tenant understands and agrees that the granting of the concessions and agreements hereunder is highly confidential and that, except as required by law, neither Tenant nor any of its officers, directors, employees, representatives, agents and all others working for Tenant shall disclose either (i) the fact that Landlord has granted any such concessions and agreements to Tenant, in any form, and/or (ii) the type or amount of such concessions and agreements (hereinafter, the “Confidential Information”). Notwithstanding anything to the contrary set forth in this Section 9, Tenant may disclose the Confidential Information to its financial advisors and accountants for the purpose of preparing tax returns or other governmentally required information documents; provided that Tenant informs such recipients of the confidential nature of such Confidential Information and takes responsibility for such persons or entities not disclosing such Confidential Information to any other person or entity, other than those governmental entities that such persons or entities are required to disclose to.

10. Tenant’s Estoppel. Tenant hereby represents, warrants, certifies and acknowledges that, as of the date of the mutual execution of this Amendment, (i) Tenant has had the opportunity to be represented by independent counsel of its own choosing, (ii) the individual executing this Amendment on behalf of Tenant has been duly authorized to act on behalf of Tenant, (iii) to its knowledge, Landlord is not in default in any respect under the Lease; (iv) to its knowledge, Tenant does not have any defenses to its obligations under the Lease; (v) there are no offsets against Rent; and (vi) Landlord has completed all improvements and paid all allowances required to be constructed or paid by Landlord in accordance with the terms of the Lease. Tenant acknowledges and agrees that: (a) the representations herein set forth constitute a material consideration to Landlord in entering into this Amendment; (b) such representations are being made by Tenant for purposes of inducing Landlord to enter into this Amendment; and (c) Landlord is relying on such representations in entering into this Amendment.


		–4–

11. Release and Waiver of Claims. As a material inducement to cause Landlord to agree to the concessions and agreements as provided herein, Tenant hereby releases Landlord from, and hereby waives, any and all losses, costs, damages, expenses, liabilities, claims and causes of action arising from or related to Tenant’s inability or limitation to conduct operations from the Premises as a result of the COVID 19 situation, including, without limitation, any claims for, and/or rights of, termination of the Lease and/or abatement, offset and/or deferral of rent under the Lease, at law and/or in equity related to the inability of Tenant to conduct operations from the Premises as a result of the COVID 19 situation and any related “shelter in place”, eviction moratoria or similar governmental directives related thereto (collectively, the “Released Claims”). With respect to the Released Claims, Tenant acknowledges that Tenant has either been advised by legal counsel or has made itself familiar with the provisions of California Civil Code section 1542, which provides as follows: A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS THAT THE CREDITOR OR RELEASING PARTY DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE AND THAT, IF KNOWN BY HIM OR HER, WOULD HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR OR RELEASED PARTY. Tenant, being aware of the foregoing code section, hereby expressly waives any rights Tenant may have thereunder, as well as under any other statutes or common-law principles of similar effect, pertaining to the Released Claims. Notwithstanding the foregoing, except in connection with an Acceleration Event or Tenant’s failure to repay the Rent Deferral Amount as required by the terms of this Amendment, Tenant shall not be in default or otherwise in breach of the Lease with respect to the Rent Deferral Amount, and Landlord waives any right to claim that Tenant’s initial failure to pay the Rent Deferral Amount is a continuing breach of the Lease.

12. Miscellaneous. Whenever possible, each provision or portion of any provision of this Amendment will be interpreted in such manner as to be effective and valid under applicable law, but if any provision or portion of any provision of this Amendment is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability will not affect any other provision or portion of any provision in such jurisdiction and this Amendment. This Amendment, together with the Lease, constitute the entire agreement between Landlord and Tenant regarding the matters set forth herein or therein, and supersedes any and all prior and/or contemporaneous oral or written negotiations, agreements or understandings. In the event of any conflict between the terms and conditions of the Lease and the terms and conditions of this Amendment, the terms and conditions of this Amendment shall prevail. Except as specifically set forth in this Amendment, all of the terms and conditions of the Lease are and shall remain in full force and effect. This Amendment may be executed in counterparts with the same effect as if both parties hereto had executed the same document. Both counterparts shall be construed together and shall constitute a single instrument. Further, each of the parties to this Amendment (i) has agreed to permit the use from time to time, where appropriate, of telecopy or other electronic signatures (including, without limitation, DocuSign) in order to expedite the transaction contemplated by this Amendment, (ii) intends to be bound by its respective telecopy or other electronic signature, (iii) is aware that the other will rely on such telecopied or other electronically transmitted signature, and (iv) acknowledges such reliance and waives any defenses to the enforcement of this Amendment and the documents affecting the transaction contemplated by this Agreement based on the fact that a signature was sent by telecopy or electronic transmission only. Submission of this Amendment by Landlord is not an offer to enter into this Amendment but rather is a solicitation for such an offer by Tenant. Neither party shall be bound by this Amendment until this Amendment has been fully executed and delivered. Time is of the essence of this Amendment and the provisions contained herein.


		–5–

13. No Further Modification. Except as specifically set forth in this Amendment, all of the terms and provisions of the Lease shall remain unmodified and in full force and effect.

Premises:		91,910 rentable square feet (“RSF”) (measured in accordance with the latest applicable BOMA standard of measurement of floor area, provided, however, that Landlord may from time to time remeasure the Premises and/or the Building in accordance with the latest applicable BOMA standard of measurement of floor area, as reasonably determined by Landlord; provided further, however, that any such re-measurement shall not affect Tenant’s Proportionate Share or the amount of Base Rent payable for, or the amount of any tenant allowance applicable to), consisting of the entire rentable area of the building commonly known as 1430 Harbor Bay Parkway, Alameda, CA (the “Building”). The Premises is outlined on the plan attached to the Lease as Exhibit A. The land on which the Building is located (the “Land”) is described on Exhibit B.

As of the Lease Date, the Complex is comprised of the following buildings and land in the Business Park: (i) the Building (1430 Harbor Bay Parkway), (ii) 1410 Harbor Bay Parkway, (iii) 1995 North Loop Road, (iv) 2065 North Loop Road, (v) 2095 North Loop Road, and (vi) 2115 North Loop Road. Landlord and Tenant anticipate delivery of possession of the Premises in two (2) phases. As part of the Tenant Improvements (as hereinafter defined), Tenant will initially demise the Building so that the Premises contains approximately 45,955 RSF (the “Phase I Premises”). The remainder of the Building, containing approximately 45,955 RSF, comprises the “Phase II Premises”. Each of the Phase I Premises and the Phase II Premises is also sometimes generally referred to in the Lease as a “Phase” of the Premises.


Term:		Approximately one hundred twenty-three (123) months, commencing on the Commencement Date and ending at 5:00 p.m. local time on the last day of the one hundred twentieth (120th) full calendar month following the Phase II Premises Commencement Date (as hereinafter defined), subject to adjustment and earlier termination as provided in the Lease.

Commencement Date:		The earlier to occur of: (a) the date on which the Tenant Improvements in the Phase I Premises are substantially completed and Tenant receives a certificate of occupancy for the Phase I Premises (or, if applicable, a temporary certificate of occupancy for the Phase I Premises); and (b) July 15, 2022 (the “Outside Commencement Date”). Tenant shall not be permitted to commence business operations in any portion of the Phase I Premises prior to issuance of a certificate of occupancy (or temporary certificate of occupancy) for the Phase I Premises.

Phase II Premises Commencement Date:		September 1, 2022.

Base Rent:		Base Rent shall be the following amounts for the following periods of time:


Lease Month	Annual Base Rent Rate Per Rentable Square Foot		Monthly Base Rent
1 - 12	$	45.00	$	344,662.50
13 - 24	$	46.35	$	355,002.38
25 - 36	$	47.74	$	365,652.45
37 - 48	$	49.17	$	376,622.02
49 - 60	$	50.65	$	387,920.68
61 - 72	$	52.17	$	399,558.30
73 - 84	$	53.73	$	411,545.05
85 - 96	$	55.34	$	423,891.40

121 - Expiration Date	$	60.48	$	463,197.58


		As used herein, the term “Lease Month” shall mean each calendar month during the Term (and if the Commencement Date does not occur on the first (1^st) day of a calendar month, the period from the Commencement Date to the first (1^st) day of the next calendar month shall be included in the first (1^st) Lease Month for purposes of determining the duration of the Term and the monthly Base Rent rate applicable for such partial month). The Base Rent table set forth above is computed for all of the Premises (i.e., the Phase I Premises and Phase II Premises). From the Commencement Date through the date immediately preceding the Phase II Premises Commencement Date, Tenant shall pay the Base Rent payable solely with respect to the Phase I Premises (“Phase I Premises Base Rent”). The Phase I Premises Base Rent will be calculated by multiplying the applicable monthly Base Rent set forth in the above table by 0.5 (i.e., 50%) (the “Phase I Premises Rent Factor”). The Phase I Premises Rent Factor is a reasonable approximation of the ratio that the RSF of the Phase I Premises bears to the RSF of the entire Premises, which has been agreed to by the parties and will not be subject to adjustment based on whether the Phase I Premises actually contains more or less than 45,955 RSF. From and after the Phase II Premises Commencement Date, Tenant shall pay Base Rent for all of the Premises as set forth in the Base Rent table. Phase I Premises Base Rent and the Base Rent payable solely with respect to the Phase II Premises (“Phase II Premises Base Rent”) are subject to abatement as set forth in Section 4 below.

Security Deposit:		$2,760,000.00 (Letter of Credit), subject to the accrual and burndown provisions set forth in Section 6 of this Lease.

Rent:		Base Rent, Additional Rent, Taxes, and Insurance (each as defined in Exhibit C hereto), and all other sums that Tenant may owe to Landlord or otherwise be required to pay under the Lease.

Tenant Improvements:		See Work Agreement - Exhibit D.

Tenant Improvement Allowance:		$190 per RSF; total amount of $17,462,900.00 (See Work Agreement - Exhibit D).

Permitted Use:		Research and development, clinical cGMP manufacturing, warehousing, laboratories and production, and all other legally permissible uses incidental thereto, and for no other purpose whatsoever. See Exhibit E.


Tenant’s Proportionate Share:	100%, which is the percentage obtained by dividing (a) the number of RSF in the Premises as stated above by (b) the RSF in the Building, which at the time of execution of the Lease is 91,910 RSF. Landlord and Tenant stipulate that the number of RSF in the Premises and in the Building set forth above is conclusive as to the square footage in existence on the Lease Date and shall be binding upon them through the Term. The foregoing notwithstanding, from the Commencement Date through the date immediately preceding the Phase II Premises Commencement Date, Tenant’s Proportionate Share will be 50% (“Tenant’s Proportionate Share for the Phase I Premises”), which is Tenant’s Proportionate Share multiplied by the Phase I Premises Rent Factor.

Initial Liability Insurance Amount:	$5,000,000

Parking Spaces:	221 parking spaces, which constitute all of the parking spaces in the Parking Area, subject to such terms, conditions and regulations as may be required by Landlord from time to time, at no charge to Tenant through the term of the Lease.

The IC also encourages these reports to include information on any of the Licensee’s public service activities that relate to the Licensed Patent Rights. If [***], the Licensee shall [***]. In any annual report, the Licensee may propose amendments to the Commercial Development Plan, acceptance of which by the IC may not be denied unreasonably. The Licensee agrees to [***] by the IC to evaluate the Licensee’s performance under this Agreement. The Licensee may amend the Benchmarks at any time upon written approval by the IC. The IC shall not unreasonably withhold approval of any request of the Licensee to extend the time periods of this schedule if the request is supported by a reasonable showing by the Licensee of diligence in its performance under the Commercial Development Plan and toward bringing the Licensed Products to the point of Practical Application as defined in 37 C.F.R. §404.3(d). The Licensee shall [***] in the plan originally submitted.

9.3

9.4

The Licensee shall submit to the IC, within [***] after each calendar half-year ending June 30 and December 31, a royalty report, as described in the example in Appendix F, setting forth for the preceding half-year period the amount of the Licensed Products sold or Licensed Processes practiced by or on behalf of the Licensee in each country within the Licensed Territory, the Net Sales, and the amount of royalty accordingly due.

The royalty report shall be certified as correct by an authorized officer of the Licensee and shall include a detailed listing of all deductions made under Paragraph 2.18 to determine Net Sales made under Article 6 to determine royalties due. The royalty report shall also [***] for the Licensed Product(s) sold in the United States.

9.5

The Licensee agrees to forward semi-annually to the IC a copy of these reports received by the Licensee from its sublicensees during the preceding half-year period as shall be pertinent to a royalty accounting to the IC by the Licensee for activities under the sublicense.

9.6

9.7

9.8

Additional royalties may be assessed by the IC on any payment that is more than [***] overdue at the rate of [***] per month or, if lower, the maximum rate permitted by applicable law. This [***] per month rate may be applied retroactively from the original due date until the date of receipt by the IC of the overdue payment and additional royalties. The payment of any such additional royalties shall not prevent the IC from exercising any other rights it may have as a consequence of the lateness of any payment.

9.9

10.	PERFORMANCE

10.1

The Licensee shall use its reasonable commercial efforts to bring the Licensed Products and the Licensed Processes to Practical Application. “Reasonable commercial efforts” for the purposes of this provision shall include adherence to the Commercial Development Plan in Appendix E and performance of the Benchmarks in Appendix D.

The Licensee may request the Government to initiate or join in any suit if necessary to avoid dismissal of the suit. Should the Government be made a party to any suit, [***] any costs, expenses, or fees which the Government incurs as a result of the motion or other action, including all costs incurred by the Government in opposing the motion or other action. In all cases, the Licensee agrees to keep the IC reasonably apprised of the status and progress of any litigation. Before the Licensee commences an infringement action, the Licensee shall notify the IC and give careful consideration to the views of the IC and to any potential effects of the litigation on the public health in deciding whether to bring suit. If the Licensee elects not to bring an action to enforce any Licensed Patent Rights against any infringement, the IC, at its option, may do so at its own expense.

11.5

(a)

defend the suit in its own name, at its own expense, and on its own behalf for presumably valid claims in the Licensed Patent Rights;

(b)

in any suit, ultimately to enjoin infringement and to collect for its use, damages, profits, and awards of whatever nature recoverable for the infringement; and

(c)

settle any claim or suit for declaratory judgment involving the Licensed Patent Rights-provided, however, that the IC and appropriate Government authorities shall have the first right to take these actions and shall have a continuing right to intervene in the suit; and

(d)

if the IC does not notify the Licensee of its intent to respond to the legal action within a reasonable time, the Licensee shall be free to do so. The Licensee shall take no action to compel the Government either to initiate or to join in any declaratory judgment action. The Licensee may request the Government to initiate or to join any suit if necessary to avoid dismissal of the suit. Should the Government be made a party to any suit by motion or any other action of the Licensee, the Licensee shall reimburse the Government for any costs, expenses, or fees, which the Government incurs as a result of the motion or other action. If the Licensee elects not to defend against the declaratory judgment action, the IC, at its option, may do so at its own expense. In all cases, the Licensee agrees to keep the IC reasonably apprised of the status and progress of any litigation. Before the Licensee commences an infringement action, the Licensee shall notify the IC and give careful consideration to the views of the IC and to any potential effects of the litigation on the public health in deciding whether to bring suit.

11.5

In any action under Paragraphs 11.2 or 11.3 the expenses including costs, fees, attorney fees, and disbursements, shall be paid by the Licensee. The value of any recovery made by the Licensee through court judgment or settlement shall be [***].

Senti Bio Enters Collaboration with Spark Therapeutics to Develop Next-Generation Precision Gene

Therapies

Collaboration combines Senti Bio’s leading-edge gene circuit technology platform and high-throughput synthetic promoter design capabilities with Spark Therapeutics’ investigational gene therapies targeting the central nervous system, eye or liver -

Senti Bio is potentially eligible to receive upfront, opt-in and milestone payments exceeding $645 million

South San Francisco, Calif., April 13, 2021 —Senti Biosciences, a leading gene circuit company, today announced a collaboration and option agreement with Spark Therapeutics, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), to apply Senti Bio’s gene circuit technology to the development of next-generation precision gene therapies directed toward specific cell types in the central nervous system (CNS), eye or liver. Created from novel and proprietary combinations of DNA sequences, gene circuits reprogram cells with biological logic to sense inputs, compute decisions and respond to their environments for defined therapeutic applications.

Senti Bio has designed, built and tested thousands of sophisticated gene circuits to drive its internal therapeutic pipeline and to deploy into multiple cell and gene therapy delivery modalities across diverse therapeutic areas. Senti Bio’s broad gene circuit technology platform includes high-throughput approaches to design and test highly potent and specific Smart Sensors that are responsive to cell-type and/or cell-state specific biomarkers. These Smart Sensors include synthetic promoters, which are compact DNA sequences engineered to more precisely regulate the expression of therapeutic genes. Spark Therapeutics will apply Senti Bio’s Smart Sensors gene circuit platform towards the goal of developing gene therapies that achieve cell type- or disease-selective expression of therapeutic payloads.

“We view gene circuits as a critical component of any advanced cell and gene therapy, regardless of therapeutic area or delivery modality. This collaboration with Spark Therapeutics aligns with our goal of enabling truly dynamic therapies that have the ability to discriminate between certain cell types, selectively express various payloads, and respond to diverse disease environments,” said Tim Lu, MD, PhD, chief executive officer of Senti Bio. “We are extremely impressed by the capabilities and know-how of Spark Therapeutics specifically in the area of gene therapy, and we look forward to bringing our mutual expertise together under this collaboration to harness the power of gene circuits to develop gene therapies that are clinically meaningful to patients.”

Under the terms of the agreement, Senti Bio will be responsible for designing, building, and testing cell type- and disease specific-synthetic promoters for use in certain CNS, ocular or liver-directed gene therapies. Spark Therapeutics will receive the option to exclusively license a defined number of synthetic promoters emerging from the collaboration for use in developing gene therapy products in specified indications. Upon option exercise, Spark Therapeutics will be responsible for conducting preclinical, clinical and commercialization activities for any gene therapy candidates that incorporate Senti Bio’s licensed synthetic promoters.

Senti Bio will receive an upfront payment as well as funding to support its research activities, and upon option exercise will be eligible to receive an option exercise payment as well as development, regulatory, and sales milestone payments in addition to royalties on a per product basis. The aggregate potential value of upfront, opt-in and milestone payments to Senti Bio may exceed $645 million.

About Senti Bio

Our mission is to create a new generation of smarter medicines that outmaneuver complex diseases in ways previously inconceivable. We have built a synthetic biology platform that enables us to program next-generation cell and gene therapies with what we refer to as “gene circuits.” These gene circuits, which are created from novel and proprietary combinations of DNA sequences, reprogram cells with biological logic to sense inputs, compute decisions and respond to their cellular environments. We are designing gene circuits to improve the “intelligence” of cell and gene therapies in order to enhance their therapeutic effectiveness against a broad range of diseases that conventional medicines are unable to address.

If the IC decides not to prepare, file, prosecute, or maintain any patent applications or patents included in the Licensed Patent Rights, and Licensee is in good standing on the payment of patent reimbursement royalties, the IC shall notify Licensee at least [***] prior to any filing, payment, or other deadlines when practicable. In such case, the Licensee and any Third Party to an Additional License that is in good standing on the payment of patent reimbursement royalties shall promptly discuss which party shall have the right, but not the obligation, to assume, at its own expense, the responsibility for the preparation, filing, prosecution, and maintenance of any and all patent applications or patents included in such Licensed Patent Rights. If Licensee elects to assume such responsibility, it shall, on an ongoing basis, promptly furnish copies of all patent-related documents to the IC. In this event, the Licensee shall, subject to the prior approval of the IC, select registered patent attorneys or patent agents to provide these services on behalf of the Licensee and the IC. The IC shall provide appropriate powers of attorney and other documents necessary to undertake this action to the patent attorneys or patent agents providing these services. The Licensee and its attorneys or agents shall consult with the IC in all aspects of the preparation, filing, prosecution and maintenance of patent applications and patents included within the Licensed Patent Rights and shall provide the IC sufficient opportunity to comment on any document that the Licensee intends to file or to cause to be filed with the relevant intellectual property or patent office

7.3

Each party shall promptly inform the other as to all matters that come to its attention that may affect the preparation, filing, prosecution, or maintenance of the Licensed Patent Rights and permit each other to provide comments and suggestions with respect to the preparation, filing, prosecution, and maintenance of the Licensed Patent Rights, which comments and suggestions shall be considered by the other party.

8.	RECORD KEEPING

8.1

The Licensee agrees to keep accurate and correct records of the Licensed Products made, used, sold, or imported and the Licensed Processes practiced under this Agreement appropriate to determine the amount of royalties due the IC. These records shall be retained for at least [***] following a given reporting period and shall be available during normal business hours for inspection, at the expense of the IC, by an accountant or other designated auditor selected by the IC and reasonably acceptable to Licensee for the sole purpose of verifying reports and royalty payments hereunder. The IC may conduct such audits no more than once per calendar year, and may inspect records from a particular reporting period only once. The accountant or auditor shall sign Licensee’s standard confidentiality agreement prior to the inspection and shall only disclose to the IC information relating to the accuracy of reports and royalty payments made under this Agreement. If an inspection shows an underreporting or underpayment in excess of [***] for any [***] period, then the Licensee shall reimburse the IC for the cost of the inspection at the time the Licensee pays the unreported royalties, including any additional royalties as required by Paragraph 9.8. All royalty payments required under this Paragraph shall be due within [***] of the date the IC provides to the Licensee notice of the payment due. If any inspection shows an overpayment by Licensee for any period, then Licensee shall be permitted to credit the amount of such overpayment against any future amounts owed by Licensee under this Agreement.

The IC and the Licensee agree to notify each other promptly of each infringement or possible infringement of the Licensed Patent Rights in the Licensed Fields of Use, as well as, any facts which would be reasonably expected to affect the validity, scope, or enforceability of the Licensed Patent Rights of which either party becomes aware.

11.2

Pursuant to this Agreement and the provisions of 35 U.S.C. Chapter 29, the Licensee may:

(a)

bring suit in its own name, at its own expense, and on its own behalf for infringement of presumably valid claims in the Licensed Patent Rights;

(b)

in any suit, enjoin infringement and collect for its use, damages, profits, and awards of whatever nature recoverable for the infringement; or

Should the Government be made a party to any such suit by motion or any other action by Licensee, [***] any reasonable costs, expenses, or fees which the Government incurs as a result of the motion or other action. In all cases, the Licensee agrees to keep the IC reasonably apprised of the status and progress of any such litigation. Before the Licensee commences an infringement action, the Licensee shall notify the IC and give careful consideration to the views of the IC and to any potential effects of the litigation on the public health in deciding whether to bring suit. If the Licensee elects not to bring an action to enforce any Licensed Patent Rights against any infringement, the IC, at its option, may do so at its own expense.

11.3

(a)

defend the suit in its own name, at its own expense, and on its own behalf for presumably valid claims in the Licensed Patent Rights;

(c)

(d)

11.4

In any action under Paragraphs 11.2 or 11.3, the expenses incurred by Licensee, including costs, fees, attorney fees, and disbursements, shall be paid by the Licensee.

[***]	CONFIDENTIAL	NIH Patent License Agreement--Exclusive Model 10-

2015	Page 18 of 33	[SentiBio] Final [5-3-2021]

(a)

(b)

has not used commercially reasonable efforts to achieve the Benchmarks as may be modified under Paragraph 9.2;

13.7

When the public health and safety so require, and after providing the Licensee a [***] opportunity to respond, the IC shall have the right to require the Licensee to grant sublicenses to responsible applicants, on reasonable terms, in any Licensed Fields of Use under the Licensed Patent Rights, unless the Licensee can reasonably demonstrate that the granting of the sublicense would not materially increase the availability to the public of the subject matter of the Licensed Patent Rights. The IC shall not require the granting of a sublicense unless the responsible applicant has first negotiated in good faith with the Licensee.

If the Parties should resolve such dispute, a memorandum setting forth their agreement shall be prepared and signed by both Parties at either Party’s request. If the Parties are unable to resolve any dispute, or if the JSC is unable to resolve any dispute pursuant to Section 2.2(c), such remaining dispute shall be resolved pursuant to Section 11.3.

11.2 Executive Escalation; Expert Resolution. If Senti desires to dispute BlueRock’s claim (a) pursuant to Section 3.8 that a Collaboration Program Option Package was incomplete, (b) pursuant to Section 3.9(b) that the Research Technology Transfer was incomplete, (c) pursuant to Section 3.9(c) that the Evaluation Technology Transfer was incomplete, or (d) pursuant to Section 3.3 that the criteria in Section 3.3(a) through (c) were met, then Senti shall notify BlueRock thereof. In such event, the dispute will be referred to the Executive Officers of each of Senti and BlueRock or their respective equivalents, or designees for attempted resolution by good faith negotiations within [***] after such notice is received. If the Parties are unable to resolve such dispute within a period of [***], or other mutually agreed period, from the commencement of such good faith negotiations, either Party may initiate the Expert resolution process under this Section 11.2 by delivering a notice to the other Party. Promptly following Senti’s delivery of such notice to initiate the Expert resolution process, the Parties shall in good faith and use diligent efforts to mutually agree on an Expert; provided that, if the Parties are unable to agree on such Expert within [***] after Senti’s delivery of such notice, then each Party shall select one (1) Expert, and within [***] thereafter those two (2) Experts will select the one (1) Expert who shall resolve such dispute. Each Party shall submit to the Expert, within [***] of his or her selection, written materials, [***], that explain the basis for such Party’s assertion that the Collaboration Program Option Package, Research Technology Transfer or Evaluation Technology Transfer, as applicable, was complete or incomplete, as applicable, or whether the criteria in Section 3.3(a) through (c) were met or not met, as applicable. The Expert will determine within [***] of his or her selection whether the Collaboration Program Option Package, Research Technology Transfer or Evaluation Technology Transfer, as applicable, was complete, or if the criteria in Section 3.3(a) through (c) were met; such determination, which shall be in writing, will be binding on both Parties.

Any disputes concerning the propriety of the commencement of arbitration or the scope or applicability of this agreement to arbitrate shall be finally settled by the arbitral tribunal. The arbitral tribunal shall be comprised of a panel of three (3) independent and neutral experienced arbitrators appointed in accordance with such rules. Each Party shall nominate one (1) arbitrator, and the two (2) arbitrators so nominated shall nominate a third (3^rd) arbitrator, who shall act as the chairperson of the tribunal. Each Party shall select its arbitrator within [***] of one Party notifying the other Party that it is exercising its rights under this Section 11.3, and the two (2) arbitrators shall select the third arbitrator within [***] of their selection. The seat, or legal place, of arbitration shall be San Francisco, California.

(b) The language to be used in the arbitral proceedings will be English. The Parties acknowledge that this Agreement evidences a transaction involving interstate commerce.

(c) Based on the materials submitted, the arbitrators shall determine whether any discovery process is necessary, and, if it is, the parameters of such process with the intent of resolving the arbitration as expeditiously as possible (e.g., limiting the number of depositions and the time discovery is permitted to take). The Parties and arbitrators shall employ procedures designed to resolve the conflict by arbitration within [***] of the dispute being referred for arbitration.

(d) The arbitrators shall have no authority to award punitive or any other type of damages not measured by a Party’s compensatory damages and the arbitrators shall have no authority to grant any award or remedy other than such awards or remedies that are available under the Applicable Law. Except to the extent necessary to prepare for or conduct the arbitration, to challenge, confirm or enforce an arbitral award, as may be required in connection with a court application for interim relief in aid of arbitration, or as may be required by law, neither a Party nor any arbitrator may disclose the existence, content, or results of an arbitration without the prior written consent of both Senti and BlueRock. In no event shall arbitration be initiated after the date when commencement of a legal or equitable proceeding based on the dispute, controversy or claim would have been barred by the applicable statute of limitations under the laws of the Commonwealth of Massachusetts.

(e) Each Party shall bear its own attorneys’ fees, costs and disbursements arising out of the arbitration, and shall [***]. Each Party agrees to fully perform and satisfy any arbitration award made against it within [***] of the service of the award. Judgment on the award may be entered in any court of competent jurisdiction.

11.4 Patent and Trademark Disputes. Any dispute, controversy, or claim relating to the scope, validity, enforceability, or infringement of any patent rights covering the manufacture, use, or sale of any product or of any trademark rights relating to any product shall be submitted to a court of competent jurisdiction in the country or jurisdiction in which such patent or trademark rights were granted or arose.

11.5 Injunctive Relief. Nothing contained in this Agreement shall preclude either Party from seeking interim or other provisional equitable relief from a court of competent jurisdiction to preserve the status quo or prevent irreparable harm, and such an action may be filed and maintained notwithstanding any ongoing good faith negotiations by the Executive Officers.

Senti Bio and BlueRock Therapeutics Enter Collaboration to Develop Gene Circuit-Engineered Cell Therapies

for Regenerative Medicine

- Collaboration combines BlueRock’s leading induced pluripotent stem cell (iPSC) platform technology and

genome biology expertise with Senti Bio’s proprietary gene circuit technology platform, including Smart

Sensors and Regulator Dials -

CAMBRIDGE, Mass. and SOUTH SAN FRANCISCO, Calif., May 2X, 2021—BlueRock Therapeutics LP, a leading engineered cell therapy company and a wholly-owned and independently operated subsidiary of Bayer AG, and Senti Biosciences, Inc. (Senti Bio), a leading gene circuit company, today announced a collaboration and option agreement to apply Senti Bio’s gene circuit technology to the development of BlueRock’s next-generation engineered cell therapies for a potentially broad array of therapeutic areas, including but not limited to neurology, cardiology and immunology within the field of regenerative medicine.

Under the terms of the agreement, Senti Bio will be responsible for designing, building and testing cell state- and disease- specific Smart Sensors and Regulator Dials for use in BlueRock Therapeutics’ regenerative medicine product candidates. BlueRock Therapeutics will receive the option to license gene circuits emerging from the collaboration for cell therapy products in specified indications. Upon option exercise, BlueRock Therapeutics will be responsible for conducting preclinical, clinical and commercialization activities for any cell therapy candidates that incorporate Senti Bio’s licensed gene circuits.

“There is tremendous opportunity at the intersection of cell, gene and systems biology. With control of all three axes, we believe we can further engineer the cell’s inherent potential to integrate multiple physiologic inputs to produce powerful therapeutic benefit in vivo,” said Emile Nuwaysir, PhD, President and Chief Executive Officer of BlueRock. “We are excited to bring together Senti Bio’s expertise in gene circuits with BlueRock’s deep understanding of engineered cells to enhance the efficacy, precision, and control of BlueRock’s future cell therapy products.”

Through this collaboration, Senti Bio will seek to bolster BlueRock’s cell+gene platform by developing gene circuits to precisely control cell differentiation and therapeutic payload expression, in an effort to accelerate BlueRock’s efforts to create next-generation cellular therapies, and further consolidate Bayer’s strategy in cell and gene therapies. It is a step forward in BlueRock and Bayer’s ambition to be at the forefront of innovationin cell and gene therapies, pioneering technology to offer the safest, highest quality and most efficient options for patients.

Tim Lu, MD, PhD, Chief Executive Officer of Senti Bio commented, “We are engineering gene circuits to reprogram cells with biological logic to sense inputs, compute decisions and respond to their cellular environments. By combining BlueRock’s iPSC platform with our sophisticated gene circuits, we believe that we have the potential to create the next generation of programmable regenerative medicines together.”

Senti Bio is developing proprietary engineered gene circuits designed to reprogram cells to sense inputs, compute decisions and respond with outputs. The company’s four core categories of gene circuits in development include Smart Sensors, Logic Gating, Regulator Dials and Multi-Arming, each of which is designed to confer greater efficacy, precision and control to cell and gene therapies. These gene circuits are driving Senti Bio’s oncology-focused therapeutics pipeline and enable potential collaborations involving other cell and gene therapies.

BlueRock Therapeutics develops engineered cell therapies using a proprietary cell+gene platform. Genetically engineered induced pluripotent stem cells (iPSCs) provide a highly consistent and unlimited source for allogeneic cell therapies. These cells can be differentiated into a wide variety of therapeutic cell types to potentially treat diseases across neurology, cardiology and immunology indications, as well as others. BlueRock Therapeutics plans to apply Senti Bio’s Smart Sensor and Regulator Dial gene circuit technology platform towards the goal of developing highly sophisticated engineered cell therapies.

About Smart Sensors and Regulator Dials

Smart Sensors are gene circuits designed to precisely detect cell type or disease environments, and thus distinguish between the “disease state” and “healthy state.” For example, Smart Sensors can be engineered to detect whether certain conditions, or disease biomarkers, are present before countering with a specific therapeutic response. These Smart Sensors include synthetic promoters, which are compact DNA sequences engineered to more precisely regulate the expression of genes. Conventional medicines are generally unable to dynamically change their behavior in response to cell- or disease-specific conditions.

Regulator Dials are gene circuits designed to enable the precise tuning of therapeutic activity from a cell or gene therapy product. For example, Regulator Dials can be engineered to regulate therapeutic payload expression in response to varying concentrations of FDA-approved drugs. Regulator Dials are expected to enable the exogenous regulation of next-generation cell and gene therapies even after they have been delivered in vivo. Most existing cell and gene therapies cannot be modulated once they have been delivered into patients.

About Senti Bio

Our mission is to create a new generation of smarter medicines that outmaneuver complex diseases in ways previously inconceivable. To accomplish this mission, we are building a synthetic biology platform that could enable us to program next-generation cell and gene therapies with what we refer to as “gene circuits”. These gene circuits, which are created from novel and proprietary combinations of DNA sequences, are intended to reprogram cells with biological logic to sense inputs, compute decisions and respond to their cellular environments. We are designing gene circuits to improve the “intelligence” of cell and gene therapies in order to enhance their therapeutic effectiveness against a broad range of diseases that conventional medicines do not readily address.

About BlueRock Therapeutics

BlueRock Therapeutics is an engineered cell therapy company with a mission to develop regenerative medicines for intractable diseases. The company’s cell+gene platform enables the creation, manufacture, and delivery of authentic cell therapies with engineered functionality by simultaneously harnessing pluripotent cell biology and genome editing. This enables an approach where, in theory, any cell in the body can be manufactured and any gene in the genome can be engineered for therapeutic purposes. The platform is broadly applicable, but the company is focused today in neurology, cardiology, and immunology. In August 2019, the company was acquired by Bayer Pharmaceuticals, for an enterprise value of $1B in upfront and milestone payments. For BlueRock this marks the next step in the journey to prove degenerative disease is reversible, and to bring our revolutionary new medicines to the patients who desperately need them.
