 EXPLANATORY NOTE
 This Amendment No. 1 ("Amendment No. 1") to the Annual Report on Form 10-K of Senti Biosciences, Inc. (the "Company," "we," "our" or "us") for the fiscal year ended December 31, 2023 as filed with the Securities and Exchange Commission (the "SEC") on March 21, 2024 (the "Original Annual Report"), is being filed solely to include in the Original Annual Report the information required by Part III (Items 10, 11, 12, 13 and 14) of Form 10-K. Because the Company has determined that it will not file its definitive proxy statement within 120 days following the last day of its last fiscal year, the Company is providing Items 10, 11, 12, 13, and 14 of Part III of Form 10-K in this Amendment No. 1.
 This Amendment No. 1 amends and restates in their entirety Items 10 through 14 of the Original Annual Report. As required by Rule 12b-15 under the Securities and Exchange Act of 1934, as amended, new certificates of our Chief Executive Officer and Chief Financial Officer are being filed as exhibits to this Amendment No. 1. Accordingly, Item 15(a)(3) of Part IV is amended to include the currently dated certifications as exhibits. Because no financial statements have been included in this Amendment No. 1 and this Amendment No. 1 does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 4 and 5 of the certifications have been omitted. In addition, because no financial statements are included in this Amendment No. 1, new certifications of the Company's Chief Executive Officer and Chief Financial Officer pursuant to Section 906 of the Sarbanes-Oxley Act of 2002 are not required to be included with Amendment No. 1.
 Except as otherwise expressly noted herein, this Amendment No. 1 does not amend any other information set forth in the Original Annual Report, and we have not updated disclosures contained therein to reflect any events that occurred at a date subsequent to the date of the filing of the Original Annual Report. Accordingly, this Amendment No. 1 should be read in conjunction with the Original Annual Report and our other filings with the SEC. Certain capitalized terms used and not otherwise defined in this Amendment No. 1 have the meanings given to them in the Original Annual Report.

Thereafter, Dr. Lu earned his M.D. from Harvard Medical School and his Ph.

 We believe Dr. Lu is qualified to serve on our board of directors due to his extensive experience in the field of synthetic biology, as well as the perspective and experience he brings as our Chief Executive Officer.

 Board Diversity
 Our Corporate Governance Guidelines provide that diversity of background and experience should be considered in determining director candidates as well as other factors such as a candidate's character, judgment, skills, education, expertise and absence of conflicts of interest. However, we do not have a formal policy concerning the diversity of the board of directors. Our priority in selection of board members is identification of members who will further the interests of our stockholders through their established records of professional accomplishment, their ability to contribute positively to the collaborative culture among board members, and their knowledge of our business and understanding of the competitive landscape in which we operate and adherence to high ethical standards. Although the nominating and corporate governance committee does not have a formal diversity policy and does not follow any ratio or formula with respect to diversity in order to determine the appropriate composition of the board of directors, the nominating and corporate governance committee and the full board of directors are committed to creating a board of directors that promotes our strategic objectives and fulfills its responsibilities to our stockholders, and considers diversity of gender, race, national origin, education, professional experience, and differences in viewpoints and skills when evaluating proposed director candidates.
 We comply with Nasdaq Rule 5605 by having three diverse directors (50%), including two directors who self-identify as Female and one director who self-identifies as an underrepresented minority. The following table provides information regarding the gender and demographic diversity of our directors, based on each director's voluntary self-identified characteristics.

 Nominating and Corporate Governance Committee
 Our nominating and corporate governance committee consists of Edward Mathers and James J. (Jim) Collins, Ph. D.. The chair of the nominating and corporate governance committee is Edward Mathers. Our board of directors has determined that each member of the nominating and corporate governance committee satisfies the independence requirements under the Nasdaq Listing Rules.
 Specific responsibilities of our nominating and corporate governance committee include:
 • identifying and evaluating candidates, including the nomination of incumbent directors for reelection and nominees recommended by stockholders, to serve on our board of directors;
 • considering and making recommendations to our board of directors regarding the composition and chairpersonship of the board of directors and committees of the board of directors;

 • periodically preparing or assembling materials and conducting sessions for continuing education of our board of directors regarding effective discharge of duties; and

 Our nominating and corporate governance committee identifies candidates for director nominees in consultation with management, through the use of search firms or other advisors, through the recommendations submitted by stockholders or through such other methods as the nominating and corporate governance committee deems to be helpful to identify candidates. Once candidates have been identified, the nominating and corporate governance committee confirms that the candidates meet all of the minimum qualifications for director nominees established by the nominating and corporate governance committee. The nominating and corporate governance committee may gather information about the candidates through interviews, detailed questionnaires, comprehensive background checks or any other means that the nominating and corporate governance committee deems to be appropriate in the evaluation process. The nominating and corporate governance committee then meets as a group to discuss and evaluate the qualities and skills of each candidate, both on an individual basis and taking into account the overall composition and needs of our board of directors. Based on the results of the evaluation process, the nominating and corporate governance committee recommends candidates for the board of directors' approval to fill a vacancy or as director nominees for election to the board of directors by our stockholders each year in the class of directors whose term expires at the relevant annual meeting. Our nominating and corporate governance committee operates under a written charter that satisfies the applicable Nasdaq Listing Rules and a copy of the nominating and corporate

 governance committee charter is available on our website, at  "Investors - Corporate Governance - Documents & Charters."
 Director Independence
 We adhere to the rules of Nasdaq in determining whether a director is independent. Our board of directors has consulted with its counsel to ensure that the board of directors' determinations are consistent with those rules and all relevant securities and other laws and regulations regarding the independence of directors. 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. Our board of directors has determined that Brenda Cooperstone, M.D., Susan Berland, Edward Mathers, Omid Farokhzad, M.D., and James J. (Jim) Collins, Ph. D. are considered independent directors. Our independent directors have regularly scheduled meetings at which only independent directors are present.
 Board and Committee Meetings Attendance
 During 2023, the board of directors met eleven times, the audit committee met four times, the compensation committee met seven times, and the nominating and corporate governance committee met three times. During 2023, each member of the board of directors attended in person or participated in 75% or more of the aggregate of (i) the total number of meetings of the board of directors (held during the period for which such person has been a director) and (ii) the total number of meetings held by all committees of the board of directors on which such person served (during the periods that such person served).
 Director Attendance at Annual Meeting of Stockholders
 Directors are encouraged to attend the annual meeting of stockholders to the extent practicable. We held a special meeting of stockholders in lieu of an annual meeting in 2022 to approve the proposed Business Combination, among other items. We held a regular annual meeting of stockholders in 2023 which was attended by our directors.
 Policy on Insider Trading, Pledging and Hedging of Company Stock
 Our Insider Trading Policy prohibits our executive officers, the non-employee members of our board of directors and certain other employees from engaging in the following transactions:
 • trading in the securities of the Company, whether for own account or for the account of another, while in the possession of material, nonpublic information about the Company;
 • disclosing material, nonpublic information about the Company to others who may trade on the basis of that information ("tipping").
 • selling any of our securities that they do not own at the time of the sale (referred to as a "short sale");
 • buying or selling puts, calls, other derivative securities of the Company or any derivative securities that provide the economic equivalent of ownership of any of our securities or an opportunity, direct or indirect, to profit from any change in the value of our securities or engaging in any other hedging transaction with respect to our securities;
 • using our securities as collateral in a margin account; and
 • pledging our securities as collateral for a loan (or modifying an existing pledge).
 As of the date of this Amendment No. 1, none of our executive officers or non-employee directors have previously engaged in any hedging or pledging transaction involving our securities.

 Compensation Recovery Policy
 In accordance with the requirements of the SEC and Nasdaq listing rules, the board of directors adopted a compensation recovery policy, effective as of October 2, 2023. If we are required to prepare a restatement of financial statements due to material noncompliance with any financial reporting requirement under securities laws, the compensation recovery policy requires (subject to certain limited exceptions described in the policy and permitted by the SEC and Nasdaq listing rules) that we seek to recover any incentive-based compensation that was based upon the attainment of a financial reporting measure and that was received by any current or former executive officer during the three-year period preceding the date that the restatement was required that exceeds the amount that the executive officers would have received based on the restated financial statements.
 Compensation Committee Interlocks and Insider Participation
 For the 2023 fiscal year, Brenda Cooperstone, M.D., Susan Berland, and David Epstein (prior to his resignation from our board of directors in June 2023) served as members of the compensation committee. None of the members of the compensation committee is currently, or has been at any time, an executive officer or employee of the Company, Dynamics Special Purpose Corp. ("DYNS") or Senti Sub I, Inc. ("Legacy Senti"). None of our executive officers currently serves, or has served during the last calendar year, as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving as a member of our board of directors or compensation committee.
 Code of Business Conduct and Ethics
 We have adopted a code of business conduct and ethics, or the Code of Conduct, that applies to all directors, officers and employees, including the principal executive officer, principal financial officer, principal accounting officer or controller or persons performing similar functions, and is available on our website at  In addition, we intend to post on our website all disclosures that are required by law or the Nasdaq Listing Rules concerning any amendments to, or waivers from, any provision of the Code of Conduct. The reference to our website address does not constitute incorporation by reference of the information contained at or available through the website, and you should not consider it to be a part of this Amendment No. 1. If we make any substantive amendments to, or grant any waivers from, the Code of Conduct for any officer or director, we will disclose the nature of such amendment or waiver on our website or in a current report on Form 8-K.
 Board Leadership Structure and Board's Role in Risk Oversight
 Timothy Lu, M.D., Ph. D. is our current President and Chief Executive Officer. We do not have a Chairperson of the Board or a lead independent director. In the absence of a Chairperson of the Board, our President and Chief Executive Officer presides at all meetings of our board of directors and stockholders. We believe this is appropriate for our company at this time because of (1) our size, (2) the size of our board, (3) our Chief Executive Officer is responsible for our day-to-day operations and implementing our strategy, and (4) discussion of developments in our business and financial condition and results are important parts of the discussion at board meetings and we believe it is appropriate for the Chief Executive Officer to chair those discussions. Our board of directors recognizes the time, effort and energy that the President and Chief Executive Officer is required to devote to his position in the current business environment, particularly as the board of directors' oversight responsibilities continue to grow, and will periodically evaluate the leadership structure of our board of directors.
 Risk is inherent with every business, and how well a business manages risk can ultimately determine its success. We face a number of risks, including risks relating to our financial condition, development and commercialization activities, operations, strategic direction and intellectual property. Management is responsible for the day-to-day management of risks we face, while our board of directors, as a whole and through its committees, has responsibility for the oversight of risk management. In its risk oversight role, our board of directors has the responsibility to satisfy itself that the risk management processes designed and implemented by management are adequate and functioning as designed.

 The role of the board of directors in overseeing the management of our risks is conducted primarily through committees of the board of directors, as disclosed in the descriptions of each of the committees above and in the charters of each of the committees. The full board of directors (or the appropriate board committee in the case of risks that are under the purview of a particular committee) discusses with management our major risk exposures, their potential impact on us, and the steps we take to manage them. When a board committee is responsible for evaluating and overseeing the management of a particular risk or risks, the chairperson of the relevant committee reports on the discussion to the full board of directors during the committee reports portion of the next board meeting. This enables the board of directors and its committees to coordinate the risk oversight role, particularly with respect to risk interrelationships.
 Communication with the Directors of Senti Biosciences, Inc.
 Any interested party with concerns about our company may report such concerns to any member of the board of directors or the chairman of our nominating and corporate governance committee, by submitting a written communication to the attention of such director at the following address:
 c/o Senti Biosciences, Inc.
 2 Corporate Drive, First Floor
 South San Francisco, CA, 94080
 United States
 A copy of any such written communication may also be forwarded to our legal counsel and a copy of such communication may be retained for a reasonable period of time. The director may discuss the matter with our legal counsel, with independent advisors, with non-management directors, or with our management, or may take other action or no action as the director determines in good faith, using reasonable judgment, and applying his or her own discretion.
 Communications may be forwarded to other directors if they relate to important substantive matters and include suggestions or comments that may be important for other directors to know. In general, communications relating to corporate governance and long-term corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances, and matters as to which we tend to receive repetitive or duplicative communications.
 The audit committee oversees the procedures for the receipt, retention, and treatment of complaints received by the Company regarding accounting, internal accounting controls, or audit matters, and the confidential, anonymous submission by employees of concerns regarding questionable accounting, internal accounting controls or auditing matters. The Company has also established a toll-free telephone number for the reporting of such activity, which is +1 (844) 982-1781.

 Item 11. Executive Compensation
 Non-Employee Director Compensation Policy
 In July 2022, our board of directors adopted a non-employee director compensation policy. The policy is designed to enable us to attract and retain, on a long-term basis, highly qualified non-employee directors. Under the policy, our non-employee directors are eligible to receive cash retainers (which are payable quarterly in arrears and prorated for partial years of service) and equity awards as set forth below. In addition, we reimburse non-employee directors for all reasonable out-of-pocket expenses incurred in attending meetings of our board of directors or board committees. We do not pay additional compensation for attending individual meetings of our board of directors.

 Equity Retainers
 Initial Award: An initial, one-time stock option, or Initial Award, of 125,000 shares of our common stock will be granted to each non-employee director serving on our board of directors as of July 13, 2022, the date on which the non-employee director compensation policy was adopted, and to each new non-employee director upon his or her election to the board of directors following such date. Each Initial Award vests in 36 equal monthly installments over three years from the date of grant, subject to continued service as a director, unless otherwise provided by a written agreement entered into at or prior to the time that such director ceases to serve as a member of our board. Each Initial Award expires ten years from the date of grant, and will have a per share exercise price equal to the closing price of our common stock on the date of grant.
 Annual Award: On the date of each annual meeting of stockholders of the Company following July 13, 2022, each continuing non-employee director other than a director receiving an Initial Award on such date, will receive an annual stock option award, or Annual Award, for 62,500 shares of our common stock. Each Annual Award vests in full on the earlier of the first anniversary of the date of grant or the date of the next annual meeting, subject to continued service, unless otherwise provided by a written agreement entered into at or prior to the time that such director ceases to serve as a member of our board. Each Annual Award expires ten years from the date of grant, and will have a per share exercise price equal to the closing price of our common stock on the date of grant.
 Change of Control Acceleration: All outstanding Initial Awards and Annual Awards held by a non-employee director shall become fully vested and exercisable upon a "Change of Control" (as defined in our 2022 Equity Incentive Plan, or our 2022 Plan).
 Maximum Annual Compensation
 The aggregate value of all compensation granted or paid, as applicable, to any individual for service as a non-employee director in any calendar year will not exceed $750,000 (or $1,000,000 for the first year that a non-employee director is appointed or elected to our board of directors), 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.

 Non-Employee Director Agreements
 We have entered into a scientific advisory board agreement with James (Jim) Collins, Ph. D., and previously had a consulting agreement with David Epstein, a former director who resigned from our board of directors in June 2023. The material terms of Mr. Epstein's and Dr. Collins' agreements are summarized below.
 David Epstein
 On July 1, 2022, we entered into a consulting agreement with David Epstein, or the Epstein Agreement, pursuant to which he provides certain consulting and advisory services from time to time, upon our request, that are outside the scope of the his responsibilities as a member of our board of directors. Mr. Epstein's consulting services include advice in connection with our day to day operations relating to business development, corporate strategy, portfolio construction, fundraising and other topics as may be requested by the Chief Executive Officer, such as reviewing materials and conducting outreach to potential collaborators in connection with business development, discussing and advising on clinical and regulatory strategies and operations, attending meetings other than our board of director meetings, and providing guidance on competitive therapies and other market intelligence. As consideration for such services, Mr. Epstein was entitled to receive compensation in the amount of $9,583.33 on a monthly basis, with total compensation not to exceed $115,000 in any one calendar year. The Epstein Agreement also provides for reimbursement of reasonable, out-of-pocket expenses incurred in connection with Mr. Epstein's performance of services upon our request. Pursuant to the Epstein Agreement, Mr. Epstein is subject to certain standard assignment of intellectual property and confidentiality covenants, as well as independent contractor covenants.
 On April 27, 2023, the Epstein Agreement was amended to provide for total cash payments in the aggregate amount of $67,083.31 as full cash compensation for services provided during the period from the effective date through termination. The Epstein Agreement will terminate, along with all project assignments thereunder, on the later of (i) thirty (30) days from the date of signature of the amendment, or (ii) the conclusion of the project assignment 1 under the Epstein Agreement. Additionally, in consideration of Mr. Epstein's consulting services provided to us under the Epstein Agreement, the board of directors amended Mr. Epstein's stock options on June 16, 2023 to extend the post-termination exercise period until two years after his termination of continuous service for any reason other than cause, disability or death.
 James (Jim) Collins
 On May 14, 2021, we entered into a scientific advisory board agreement with James Collins, or the Collins Agreement, pursuant to which he serves as a member and chair of our Scientific Advisory Board, or our SAB. As consideration for such services, Dr. Collins is entitled to receive (i) cash compensation in the amount of $10,500 per year (plus, for service as chair of our SAB, an additional $9,000 per year), and (ii) subject to approval by our board of directors or compensation committee, an annual stock option award of 3,522 shares, which amount is subject to adjustment in the event of a change in our capitalization. The Collins Agreement provides for such cash compensation to be paid in equal quarterly installments and each stock option award to vest over four (4) years, subject to Dr. Collins continued service with us and subject to the terms and conditions of our 2016 Plan (or other applicable equity incentive plan in effect at the time of grant). The Collins Agreement also provides for reimbursement of reasonable, out-of-pocket expenses incurred in connection with Dr. Collins' performance of services upon our request. Pursuant to the Collins Agreement, Dr. Collins is subject to certain standard assignment of intellectual property and confidentiality covenants, as well as independent contractor covenants.
 Director Compensation Table
 The following table sets forth information regarding the compensation awarded to, earned by or paid to our non-employee directors for service on our board of directors during the year ended December 31, 2023 (including, for David Epstein, who resigned from our board of directors on June 16, 2023). Dr. Lu, who is our President and Chief Executive Officer, also served on our board of directors, but did not receive any additional compensation for his service as a director and therefore is not included in the table below.

 Narrative to Summary Compensation Table
 Our compensation committee or board of directors reviews compensation annually for all employees, including named executive officers. In making compensation determinations, we consider compensation for comparable positions in the market and with peer companies, the historical compensation levels of executives, individual performance as compared to our expectations and objectives, our desire to motivate employees to achieve short- and long-term results that are in the best interests of our stockholders and a long-term commitment to the company.
 Annual Base Salaries
 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 our 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, we may also draw upon the experience of members of the board of directors with executives at other companies. The 2023 base salaries for the named executive officers were as follows: (a) $606,625 for Dr. Lu; (b) $516,460 for Dr. Rajangam; and (c) $460,013 for Dr. Knobelman.
 Non-Equity Incentive Plan Compensation
 Our named executive officers are each eligible to receive a discretionary annual bonus based on individual and company performance. In 2023, Dr. Lu was eligible to earn an annual target performance bonus equal to 55% of his 2023 base salary based on the achievement of corporate objectives. Dr. Rajangam and Dr. Knobelman were eligible to earn an annual target performance bonus equal to 40% of their respective 2023 base salary based on the achievement of both individual and corporate objectives. Payment of 2023 annual bonuses was based in part on us achieving certain research and product development, capital raising and other target goals. Based on the achievement of such goals, the compensation committee determined that Dr. Lu was entitled to 75% of his target bonus for 2023 performance, and Dr. Rajangam and Dr. Knobelman were each entitled to 84% of their respective target bonuses for 2023 performance.
 Equity Incentive Awards
 Our equity incentive awards are designed to align our interests and those of our stockholders with those of our employees and consultants, including our named executive officers.
 We have historically used stock options and RSUs as incentives for long-term compensation to the named executive officers as the return on such awards is tied to an increase in our stock price. We 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 our Business Combination, all of the equity incentive awards were made pursuant to our 2016 Stock Incentive Plan, as amended, or the 2016 Plan. Following the completion of the Business Combination, all equity incentive awards were granted under the terms of our 2022 Equity Incentive Plan, or the 2022 Plan. See "-Outstanding Equity Awards at Fiscal Year-End" below for additional information.

 Potential Payments and Benefits upon Termination or Change in Control
 Regardless of the manner in which a named executive officer's employment with us 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
 In July 2022, we entered into a Severance and Change in Control Agreement with each of Drs. Lu and Knobelman, which sets forth the terms of their severance benefits and supersedes the severance benefits to which such named executive officers were previously entitled to under their employment offer letters.
 Pursuant to each named executive officer's offer letter (or, for Drs. Lu and Knobelman, their Severance and Change in Control Agreement), each of our named executive officers is eligible to receive the following severance payments and benefits, in accordance with the terms and conditions of their respective Severance and Change in Control Agreement or offer letter, upon a termination without "cause" or upon resignation for "good reason", contingent upon the named executive officer's timely delivery to the Company of an effective release of claims, or a qualifying termination:
 • In the event of a qualifying termination, Dr. Lu is entitled to severance equal to (i) 12 months of his then current base salary, (ii) the prorated portion of his target annual bonus, (iii) all earned but unpaid annual bonus for the calendar year prior to the year in which his employment terminated, and (iv) up to 12 months of continued group health plan benefits at levels in effect at the time of termination. In lieu of the foregoing payments and benefits, if such qualifying termination occurs within 3 months before or 12 months after a "change of control", then Dr. Lu is entitled to severance equal to (i) 18 months of his then current base salary, (ii) his target annual bonus for the year of termination, (iii) all earned but unpaid annual bonus for the calendar year prior to the year in which his employment terminated, (iv) up to 18 months of continued group health plan benefits at levels in effect at the time of termination, and (v) accelerated vesting of all outstanding time-based equity awards (and the time-based vesting conditions of equity awards which vest by a combination of time-based and performance-based vesting conditions) held by Dr. Lu.
 • In the event of a qualifying termination, Dr. Knobelman is entitled to severance equal to (i) 9 months of her then current base salary, (ii) all earned but unpaid bonus for the calendar year prior to the year in which her employment terminated, and (iii) up to 9 months of continued group health plan benefits at levels in effect at the time of termination. In lieu of the foregoing payments and benefits, if such qualifying termination occurs within 3 months before or 12 months after a "change of control", then Dr. Knobelman is entitled to severance equal to (i) 12 months of her then current base salary, (ii) her target annual bonus for the year of termination, (iii) all earned but unpaid annual bonus for the calendar year prior to the year in which her employment terminated, (iv) up to 18 months of continued group health plan benefits at levels in effect at the time of termination, and (v) accelerated vesting of the time-based equity awards (and the time-based vesting conditions of equity awards which vest by a combination of time-based and performance-based vesting conditions) held by Dr. Knobelman.

 • In the event of a qualifying termination, Dr. Rajangam is entitled to severance equal to (i) 9 months of her then current base salary, (ii) all earned but unpaid bonus for the calendar year prior to the year in which her employment terminated, and (iii) up to 9 months of continued group health plan benefits at levels in effect at the time of termination. In lieu of the foregoing payments and benefits, if such qualifying termination occurs within 3 months before or 12 months after a "change of control", then Dr. Rajangam is entitled to severance equal to (i) 12 months of her then current base salary, (ii) her target annual bonus for the year of termination, (iii) all earned but unpaid annual bonus for the calendar year prior to the year in which her employment terminated, (iv) up to 18 months of continued group health plan benefits at levels in effect at the time of termination, and (v) accelerated vesting of the time-based equity awards (and the time-based vesting conditions of equity awards which vest by a combination of time-based and performance-based vesting conditions) held by Dr. Rajangam.
 The payments and benefits provided to our named executive officers in connection with a change in control may not be eligible for a federal income tax deduction pursuant to Section 280G of the Internal Revenue Code of 1986, as amended, or the Code. These payments and benefits may also subject the named executive officers to an excise tax under Section 4999 of the Code. If the payments and benefits payable to Drs. Lu, Knobelman or Rajangam in connection with a change in control would subject them to the excise tax imposed under Section 4999 of the Code, such severance benefits will be reduced if such reduction would result in a higher net after-tax benefit to such named executive officers.
 For the purposes of our named executive officers' severance benefits, the following definitions apply:
 •"cause" generally means the occurrence of any of the following: (i) the employee's material breach of their employment offer letter; (ii) any act (other than retirement) or omission which has a material and adverse effect on our business, or on the employee's ability to perform services for us, including the commission of any crime (other than minor traffic violations); or (iii) material misconduct or material neglect of the employee's duties in connection with our business or affairs.
 •"change of control" has the meaning set forth in our 2022 Plan (excluding consummation of our Business Combination).
 •"good reason" generally means the executive's termination of their own employment because of any of the following: (i) our breach of any one or more of the material provisions of the executive's employment offer letter; (ii) a material reduction by us of their annual base salary, unless they consent to such reduction or unless such reduction is applied equally, as a percentage of base salary, to all our senior executives; (iii) a material change in the geographic location at which they are required to provide services; or (iv) a material adverse change in their duties, authority, or responsibilities relative to their 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 the executive comply with notice and cure periods set forth in the applicable employment offer letter or Severance and Change in Control Agreement.
 Health and Welfare and Retirement Benefits
 Health and Welfare Benefits and Perquisites
 All of our current named executive officers are eligible to participate in our health and welfare employee benefit plans generally available to our employees, including our medical, dental, vision, disability and life insurance plans, in each case on the same basis as all of our other employees. We pay the premiums for the life, disability and accidental death and dismemberment insurance for all of our employees, including our named executive officers. We generally do not provide perquisites or personal benefits to our named executive officers.
 401(k) Plan

 We currently maintain a 401(k) retirement savings plan for our employees, including our named executive officers, who satisfy certain eligibility requirements. Our 401(k) plan is intended to qualify as a tax-qualified plan under the Code. Our named executive officers are eligible to participate in the 401(k) plan on the same basis as our other employees. The Code allows eligible employees to defer a portion of their compensation, within prescribed limits, on a pre-tax basis through contributions to the 401(k) plan. We currently provide matching 401(k) contributions to participants in the 401(k) plan, including our named executive officers.

 The Investor Rights Agreement restricts the ability of each stockholder who is a party thereto (other than DYNS) to transfer its shares of common stock (or any securities convertible into or exercisable or exchangeable for shares of common stock), subject to certain permitted transfers, for a period of one year following the Closing Date, or the General Lock-Up or, in the case of certain stockholders of Legacy Senti, 18 months following the Closing Date, or the Extended Lock-Up; provided that (A) the foregoing restrictions do not apply to any shares of common stock purchased pursuant to subscription agreements in the PIPE financing, and (B) if the last reported per share sale price of our common stock on Nasdaq, or any other national securities exchange on which our common stock is then traded, is greater than or equal to $12.00 per share over any 20 trading days within any consecutive 30-trading day period following the Closing Date, then, commencing at least 150 days after the Closing Date, the General Lock-Up will be deemed to have expired with respect to the shares of common stock subject to the General Lock-Up and the Extended Lock-Up.
 Agreement with David Epstein
 On July 1, 2022, we entered into an consulting agreement with our director, David Epstein, pursuant to which he provides certain consulting and advisory services, as is more fully described in the section titled "Non-Employee Director Compensation- Non-Employee Director Agreements".

 Agreement with James Collins
 On May 14, 2021, we entered into an agreement with our director James Collins, pursuant to which he is a member and chair of the Company's Scientific Advisory Board ("SAB"), and as more fully described in the section titled "Non-Employee Director Compensation- Non-Employee Director Agreements".
 Agreement with Seer, Inc.
 On December 23, 2022, we agreed to purchase a piece of biologics automation equipment for our research facility from Seer, Inc. (NASDAQ: SEER) for $200,000. Omid Farokhzad, a member of our board of directors, is the Chief Executive Officer of Seer. The equipment was delivered in January 2023. The consideration of $200,000, plus interest, will be paid over a two-year period. Ownership title will transfer to Senti upon final payment. The design and sale of this equipment is the main business of Seer and there is no comparable product on the market. The Audit Committee approved the purchase of the equipment at a committee meeting on March 17, 2023. The transaction was classified in the Company's books as a finance lease that commenced on March 1, 2023.
 Indemnification Agreements
 The certificate of incorporation contains provisions limiting the liability of directors, and the bylaws provide that we will indemnify each of our directors and officers to the fullest extent permitted under Delaware law. The certificate of incorporation and bylaws also provide our board of directors with discretion to indemnify our employees and other agents when determined appropriate by the board of directors.
 In addition, we have entered into or intend to enter into an indemnification agreement with each of our directors and executive officers, which will require us to indemnify them.
 Stock Option Grants to Directors and Executive Officers
 We have granted stock options to our directors and executive officers, as more fully described in Item 11 herein.
 Related Person Transactions Policy
 Our board of directors has adopted a related person transaction policy setting forth the policies and procedures for the identification, review and approval or ratification of related person transactions. This policy covers, with certain exceptions set forth in Item 404 of Regulation S-K under the Securities Act, any transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which Senti and a related person were or will be participants and the amount involved exceeds $120,000, including purchases of goods or services by or from the related person or entities in which the related person has a material interest, indebtedness and guarantees of indebtedness. In reviewing and approving or rejecting any such transactions, our audit committee will consider all relevant facts and circumstances as appropriate, such as the purpose of the transaction, the availability of other sources of comparable products or services, whether the transaction is on terms comparable to those that could be obtained in an arm's length transaction, management's recommendation with respect to the proposed related person transaction, and the extent of the related person's interest in the transaction.
 Sponsor Support Agreement
 In connection with the execution of the Business Combination Agreement, the Sponsor and each of the DYNS officers and directors entered into the Sponsor Support Agreement with DYNS and Senti. 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.
