TYRA BIOSCIENCES, INC. 

AMENDED AND RESTATED EMPLOYMENT AGREEMENT 

This Amended and Restated Employment Agreement (the “Agreement”) is entered into as of August 18, 2021, by and between
Tyra Biosciences, Inc., a Delaware corporation (the “Company”) and Esther van den Boom (“Executive” and, together with the Company, the “Parties”). This Agreement will be effective upon the
consummation of the Company’s initial public offering (the “IPO”) of its common stock (the “Effective Date”). In the event the IPO does not occur, this Agreement shall be of no force or effect and the Prior Agreement
shall continue. Capitalized terms used herein and not otherwise defined shall have those meanings set forth in Appendix I hereto. 

WHEREAS, the Company and Executive are parties to that certain Amended and Restated Employment Agreement dated as of April 16,
2021 (the “Prior Agreement”); 
 WHEREAS, the Company desires to retain the services of Executive by engaging
Executive to perform services as an employee of the Company under the terms hereof; and 
 WHEREAS, Executive desires to provide
services to the Company on the terms hereof. 
 NOW, THEREFORE, in consideration of the foregoing, and for other good and valuable
consideration, including the respective covenants and agreements set forth below, the receipt and sufficiency of which are hereby acknowledged, the Parties hereto agree as follows:

directors; (ii) serving as a member of the board of directors for for-profit organizations that are not competitors of the Company; and (iii) serving as an advisor, or as a member of an

 
advisory board of organizations that are not competitors of the Company; provided such activities do not individually or in the aggregate interfere with the performance of Executive’s
duties under this Agreement, violate the Company’s standards of conduct then in effect or raise a conflict under the Company’s conflict of interest policies. 

2. Term. The period of Executive’s employment under this Agreement shall continue until Executive’s employment
with the Company is terminated. The phrase “Term of Employment” as used in this Agreement shall refer to the entire period of employment of Executive by the Company. 

3. Compensation and Related Matters. 

(a) Annual Base Salary. Executive shall receive a base salary at the rate of $410,000 per annum (as may be increased from
time to time, the “Annual Base Salary”), subject to withholdings and deductions and as adjusted for part time status, which shall be paid to Executive in accordance with the customary payroll practices and procedures of the Company.
Such Annual Base Salary shall be reviewed by the CEO, and as applicable, the Board of Directors of the Company (the “Board”), not less than annually, and may be increased, but not decreased, in connection with any such review. 

(b) Annual Bonus. Executive shall be eligible to receive a discretionary annual bonus (the “Annual Bonus”)
based on Executive’s achievement of performance objectives in accordance with the terms set forth by the Board. Executive’s target Annual Bonus shall be equal to 40% of Executive’s Annual Base Salary (the “Target
Bonus”). Except as set forth in Section 6, Executive must be employed by the Company on the date of payment of any Annual Bonus to remain eligible to receive such Annual Bonus. Any Annual Bonus earned will be paid at the same time
annual bonuses are paid to other executives of the Company generally, subject to any limitations on payment as set forth in Section 6. 

(c) Benefits. Executive shall be entitled to participate in such employee and executive benefit plans and programs as the
Company may offer from time to time to provide to its executives, subject to the terms and conditions of such plans. Notwithstanding the foregoing, nothing herein is intended, or shall be construed, to require the Company to institute or continue
any, or any particular, plan, or benefits. 
 (d) Business Expenses. The Company shall reimburse Executive for all reasonable,
documented, out-of-pocket travel and other business expenses incurred by Executive in the performance of Executive’s duties to the Company in accordance with the

policy. 
 (f) Equity Awards. Executive shall be eligible to receive grants of equity awards in the Company’s sole

 (g) Indemnification Agreement; Insurance. As an officer of the Company,

officer of the Company. 
 4. Acceleration of Equity Awards Upon a Change in Control. Notwithstanding anything herein
to the contrary, in the event of a Change in Control, the vesting of Executive’s then outstanding options, restricted stock and other equity awards covering shares of the Company’s common stock (collectively, “Equity
Awards”) shall accelerate as of immediately prior to such Change in Control with respect to fifty percent (50%) of the unvested shares of Company common stock subject to such Equity Awards. The remaining fifty percent (50%) of the
unvested shares of Company common stock subject to Executive’s Equity Awards shall continue to vest at the same rate as immediately prior to the Change in Control, subject to Executive’s continued employment with the Company or its
successor through the applicable vesting date. Any portion of Executive’s Equity Awards that remains unvested as of the first anniversary of the Change in Control shall thereupon vest in full, subject to Executive’s continued employment
with the Company or its successor through such first anniversary. Notwithstanding the foregoing and for the avoidance of doubt, any shares subject to Equity Awards that do not accelerate immediately prior to the Change in Control in accordance with
the foregoing shall be subject to accelerated vesting in accordance with Section 6(d)(iii) below. 
 5.
Termination. 
 (a) At-Will Employment. The Company and Executive
acknowledge that Executive’s employment is and shall continue to be at-will, as defined under applicable law. This means that it is not for any specified period of time and can be terminated by Executive
or by the Company at any time, with or without advance notice, and for any or no particular reason or cause. It also means that Executive’s job duties, title, and responsibility and reporting level, work schedule, compensation, and benefits, as
well as the Company’s personnel policies and procedures, may be changed with prospective effect, with or without notice, at any time in the sole discretion of the Company (subject to any ramification such changes may have under Section 6
of this Agreement). This “at-will” nature of Executive’s employment shall remain unchanged during Executive’s tenure as an employee and may not be changed, except in an express writing
signed by Executive and the CEO. If Executive’s employment terminates for any lawful reason, Executive shall not be entitled to any payments, benefits, Equity Awards or other compensation other than as provided in this Agreement. 

(b) Notice of Termination. During the Term of Employment, any termination of Executive’s employment by the Company or by
Executive (other than by reason of death) shall be communicated by written notice (a “Notice of Termination”) from one Party hereto to the other Party hereto (i) indicating the specific termination provision in this Agreement
relied upon, if any, (ii) setting forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of Executive’s employment under the provision so indicated and (iii) specifying the date of the
termination of Executive’s employment with the Company (the “Date of Termination”). The failure by the Company to set forth in the Notice of Termination all of the facts and circumstances which contribute to a showing of Cause
shall not waive any right of the Company hereunder or preclude the Company from asserting such fact or circumstance in enforcing its rights 

  
 3 

 
hereunder. The failure by Executive to set forth in the Notice of Termination all of the facts and circumstances which contribute to a showing of Good Reason shall not waive any right of
Executive hereunder or preclude Executive from asserting such fact or circumstance in enforcing Executive’s rights hereunder. 

(c) Deemed Resignation. Upon termination of Executive’s employment with the Company for any reason, Executive shall be
deemed to have resigned from all offices and board memberships, if any, then held with the Company or any of its affiliates, and, at the Company’s request, Executive shall execute such documents as are necessary or desirable to effectuate such
resignations. 
 6. Consequences of Termination. 

(a) Release. In the event Executive’s employment with the Company terminates pursuant to Section 5, then Executive
shall be entitled to the applicable payments and benefits set forth below subject to, in the case of a termination described in Section 6(c) or 6(d), Executive delivering to the Company a waiver and release of claims agreement in standard
reasonable form approved by the Company that becomes effective and irrevocable in accordance with Section 7 hereof (a “Release”). 

(b) Payments upon Termination by the Company for Cause or by Executive Without Good Reason. Upon a termination of
Executive’s employment with the Company at any time for Cause or by Executive without Good Reason, Executive (or Executive’s estate or legal representative, as applicable) shall be entitled to receive, within thirty (30) days of the
effective date of termination of employment with the Company (whether such termination of employment is effected by the Company or Executive) (or such earlier date as may be required by applicable law): (i) any portion of Executive’s
Annual Base Salary earned through Executive’s Date of Termination not theretofore paid; (ii) any reimbursement of expenses owed to Executive under Section 3(e) above; and (iii) any accrued but unused vacation or paid time-off owed to Executive ((i)-(iii) defined as the “Accrued Obligations”). In the event Executive is terminated by the Company for Cause, Executive shall forfeit, effective as of the date
Executive engages in such conduct giving rise to his termination for Cause, all unexercised, unearned and/or unpaid Equity Awards, including without limitation, Equity Awards earned but not yet paid, all unpaid dividends and dividend equivalents and
all interest, if any, accrued on the foregoing. 
 (c) Severance Payments upon Involuntary Termination Outside a Change in Control
Period. If, outside a Change in Control Period, Executive’s employment is terminated due to an Involuntary Termination, the Company shall provide the following payments and benefits: 

(i) the Accrued Obligations; 

(ii) an amount in cash equal to (A) twelve months of Executive’s Annual Base Salary plus (B) Executive’s Target
Bonus for the calendar year in which such Involuntary Termination occurs, pro-rated based on the total number of days elapsed in the calendar year as of Executive’s Date of Termination; 

  
 4 

 (iii) fifty percent (50%) of the unvested Equity Awards held by the Executive as of
the Date of Termination will become fully vested and, if applicable, exercisable, and all restrictions and rights of repurchase thereon shall lapse with respect to all of the shares of the Company’s common stock subject thereto; and 

(iv) during the period commencing on the Date of Termination and ending on the twelve-month anniversary thereof or, if earlier, the
date on which Executive becomes eligible for comparable replacement coverage under a subsequent employer’s group health plan, subject to Executive’s valid election to continue healthcare coverage under Section 4980B of the Internal
Revenue Code of 1986, as amended (the “Code”) and the regulations thereunder (“COBRA”), the Company shall, in its sole discretion, either (A) continue to provide to Executive and Executive’s
dependents, at the Company’s sole expense, or (B) reimburse Executive and Executive’s dependents for the cost of, in either case, coverage under its group health plan (if any) at the same coverage levels in effect on the Date of
Termination (“Benefits Coverage”); provided, however, that if (1) any plan pursuant to which such benefits are provided is not, or ceases prior to the expiration of the continuation coverage period to be, exempt
from the application of Section 409A under Treasury Regulation Section 1.409A-1(a)(5), (2) the Company is otherwise unable to continue to cover Executive or Executive’s dependents
under its group health plans or (3) the Company cannot provide the benefit without violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), then, in any such case, the cash amount necessary
to maintain the Benefits Coverage shall thereafter be paid to Executive in substantially equal taxable monthly installments over the COBRA continuation period (or remaining portion thereof). 

(d) Severance Payments upon Involuntary Termination During a Change in Control Period. If, during a Change in Control Period,

(i) the Accrued Obligations; 

(ii) an amount in cash equal to (A) eighteen months of Executive’s Annual Base Salary plus (B) one hundred percent
(100%) of Executive’s Target Bonus for the calendar year in which such Involuntary Termination occurs (for the avoidance of doubt, if (x) Executive incurred an Involuntary Termination prior to a Change in Control that qualifies Executive
for severance payments under Section 6(c)(ii); and (y) a Change in Control occurs within the three (3)-month period following Executive’s Involuntary Termination that qualifies Executive for the increased benefits under this
Section 6(d)(ii), then Executive shall be entitled to a lump-sum payment of the amount calculated under this Section 6(d)(ii), less any amount already paid under Section 6(c)(ii)); 

(iii) one hundred percent (100%) of all unvested Equity Awards held by Executive as of the Date of Termination, will become fully
vested and, if applicable, exercisable, and all restrictions and rights of repurchase thereon shall lapse with respect to all of the shares of the Company’s common stock subject thereto effective on the later of (x) the Date of Termination
or (y) the date of the Change in Control (for the avoidance of doubt, if Executive’s Involuntary Termination occurs prior to a Change in Control, then any unvested portion of Executive’s outstanding Equity Awards will remain
outstanding for three (3) months or the occurrence of a 

  
 5 

 
Change in Control (whichever is earlier) so that any vesting acceleration benefits provided under this clause (iii) can be provided if a Change in Control occurs within three (3) months
following such termination (provided that in no event will the Equity Awards remain outstanding beyond the Equity Award’s maximum term or expiration date. In such case, if no Change in Control occurs within three (3) months following
Executive’s termination, any unvested portion of Executive’s Equity Awards automatically will be forfeited without having vested; and 

(iv) during the period commencing on the Date of Termination and ending on the first anniversary thereof or, if earlier, the date on
which Executive becomes eligible for comparable replacement coverage under a subsequent employer’s group health plan, subject to Executive’s valid election to continue healthcare coverage under COBRA, the Company shall, in its sole
discretion, either (A) continue to provide to Executive and Executive’s dependents, at the Company’s sole expense, or (B) reimburse Executive and Executive’s dependents for the cost of, in either case, the Benefits Coverage;
provided, however, that if (1) any plan pursuant to which such benefits are provided is not, or ceases prior to the expiration of the continuation coverage period to be, exempt from the application of Section 409A under
Treasury Regulation Section 1.409A-1(a)(5), (2) the Company is otherwise unable to continue to cover Executive or Executive’s dependents under its group health plans or (3) the Company
cannot provide the benefit without violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), then, in any such case, the cash amount necessary to maintain the Benefits Coverage shall thereafter be
paid to Executive in substantially equal taxable monthly installments over the COBRA continuation period (or remaining portion thereof). 

(e) No Other Severance. The provisions of this Section 6 shall supersede in their entirety any severance payment provisions
in any severance plan, policy, program, or other arrangement maintained by the Company except for such additional benefits otherwise approved by the Board or Compensation Committee of the Board after the date hereof. 

(f) No Requirement to Mitigate; Survival. Executive shall not be required to mitigate the amount of any payment provided for
under this Agreement by seeking other employment or in any other manner. Notwithstanding anything to the contrary in this Agreement, the termination of Executive’s employment shall not impair the rights or obligations of any Party. 

7. Release and Payment Timing. 

(a) Release. Notwithstanding anything to the contrary in this Agreement, any payments or other benefits due under this Agreement
under Sections 6(c) and 6(d) as a result of Executive’s termination of employment (other than the Accrued Obligations) are subject to Executive’s execution and delivery of a Release, as follows: (i) the Company shall deliver the
Release to Executive within five (5) days following Executive’s Date of Termination, and the Company’s failure to deliver a Release prior to the expiration of such five (5) day period shall constitute a waiver of any requirement
to execute a Release, (ii) if Executive fails to execute the Release on or prior to the Release Expiration Date (as defined below) or timely revokes Executive’s acceptance of the Release thereafter, Executive shall not be entitled to any
payments or benefits otherwise conditioned on the Release, and (iii) if the Release does not become effective and irrevocable no later than sixty (60) days following the Date of Termination (such deadline, the “Release
Deadline”), Executive shall not be entitled to any payments or benefits otherwise 

  
 6 

 
conditioned on the Release. For purposes of this Section 7, “Release Expiration Date” shall mean the date that is twenty-one
(21) days following the date upon which the Company timely delivers the Release to Executive, or, in the event that Executive’s termination of employment is “in connection with an exit incentive or other employment termination
program” (as such phrase is defined in the Age Discrimination in Employment Act of 1967), the date that is forty-five (45) days following such delivery date. 

(b) Payment Timing. The payments due under Sections 6(c)(ii) and 6(d)(ii) of this Agreement as a result of Executive’s
termination of employment shall be paid in a lump sum on the date that is sixty (60) days following the Date of Termination; provided, however, that, in the event of Executive’s Involuntary Termination during the Change in Control Period
but prior to a Change in Control, any additional amount payable to Executive under Section 6(d)(ii) in excess of the amounts payable to such Executive under Section 6(c)(ii) shall be paid in a lump sum on the date that is sixty
(60) days following the later of (x) the Date of Termination, or (y) the date of the Change in Control. 
 8. Non-Solicitation of Employees. For a period of one (1) year following Executive’s Date of Termination, Executive shall not, either directly or indirectly (a) solicit for employment through any
individual, corporation, firm, or other business, any employees, consultants, independent contractors, or other service providers of the Company or any of its affiliates, or (b) solicit any employee, consultant or other service provider of the
Company or any of its affiliates to leave the employment or consulting of or cease providing services to the Company or any of its affiliates; provided, however, that the foregoing clauses (a) and (b) shall not apply to
inbound inquiries or any general advertisement or solicitation (or any hiring pursuant to such advertisement or solicitation) that is not specifically targeted to such employees, consultants or other service providers. 

9. Golden Parachute Excise Tax. 

(a) Best Pay. Any provision of this Agreement to the contrary notwithstanding, if any payment or benefit Executive would receive
from the Company pursuant to this Agreement or otherwise (“Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code and (ii) but for this sentence, be subject to
the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment will be equal to the Reduced Amount (as defined below). The “Reduced Amount” will be either (A) the largest portion
of the Payment that would result in no portion of the Payment (after reduction) being subject to the Excise Tax or (B) the entire Payment, whichever amount 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, net of the maximum reduction in federal income taxes which could be obtained from a deduction of such state and local taxes), results in Executive’ s
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 (A) of the preceding sentence, the reduction shall occur in the manner (the “Reduction Method”) that results in the greatest economic benefit for
Executive. 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”). Notwithstanding the foregoing, if the Reduction Method or the
Pro Rata Reduction 

  
 7 

 
Method would result in any portion of the Payment being subject to taxes pursuant to Section 409A (as defined below) 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, shall be modified so as to avoid the imposition of taxes pursuant to Section 409A as follows: (1) as a first priority, the modification
shall preserve to the greatest extent possible, the greatest economic benefit for Executive as determined on an after-tax basis; (2) as a second priority, Payments that are contingent on future events
(e.g., being terminated without cause), shall be reduced (or eliminated) before Payments that are not contingent on future events; and (3) as a third priority, Payments that are “deferred compensation” within the meaning of
Section 409A shall be reduced (or eliminated) before Payments that are not deferred compensation within the meaning of Section 409A. 

(b) Accounting Firm. All determinations regarding the application of this Section 9 shall be made by an independent
accounting firm or consulting group with nationally recognized standing and substantial expertise and experience in performing calculations regarding the applicability of Section 280G of the Code and the Excise Tax retained by the Company prior
to the date of the applicable change in ownership or control (the “280G Firm”). The Company will bear all expenses with respect to the determinations by the 280G Firm required to be made hereunder. The 280G Firm engaged to make the
determinations hereunder will provide its calculations, together with detailed supporting documentation, to the Company within thirty (30) days before the consummation of a Change in Control (if requested at that time by the Company) or such
other time as requested by the Company. If the 280G Firm determines that no Excise Tax is payable with respect to a Payment, either before or after the application of the Reduced Amount, it will furnish the Company with documentation reasonably
acceptable to the Company that no Excise Tax will be imposed with respect to such Payment. Any good faith determinations of the 280G Firm made hereunder will be final, binding and conclusive upon the Company and Executive. 

10. Section 409A. 

(a) General. The intent of the Parties is that the payments and benefits under this Agreement comply with or be exempt from
Section 409A of the Code and the Department of Treasury regulations and other interpretive guidance issued thereunder, including without limitation any such regulations or other guidance that may be issued after the Effective Date,
(“Section 409A”) and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted to be in compliance therewith. If Executive notifies the Company that Executive has received advice of tax
counsel of a national reputation with expertise in Section 409A that any provision of this Agreement would cause Executive to incur any additional tax or interest under Section 409A (with specificity as to the reason therefor) or the
Company independently makes such determination, the Company and Executive shall take commercially reasonable efforts to reform such provision to try to comply with or be exempt from Section 409A through good faith modifications to the minimum
extent reasonably appropriate to conform with Section 409A, provided that any such modifications shall not increase the cost or liability to the Company. To the extent that any provision hereof is modified in order to comply with or be
exempt from Section 409A, such modification shall be made in good faith and shall, to the maximum extent reasonably possible, maintain the original intent and economic benefit to Executive and the Company of the applicable provision without
violating the provisions of Section 409A. 

  
 8 

 (b) Separation from Service. Notwithstanding any provision to the contrary in
this Agreement: (i) no amount that constitutes “deferred compensation” under Section 409A shall be payable pursuant to Section 6(c) or Section 6(d) above unless the termination of Executive’s employment constitutes
a “separation from service” within the meaning of Section 1.409A-1(h) of the Department of Treasury Regulations (“Separation from Service”); (ii) for purposes of
Section 409A, Executive’s right to receive installment payments shall be treated as a right to receive a series of separate and distinct payments; and (iii) to the extent that any reimbursement of expenses or in-kind benefits constitutes “deferred compensation” under Section 409A, such reimbursement or benefit shall be provided no later than December 31st of the year following the year in which the
expense was incurred. The amount of expenses reimbursed in one year shall not affect the amount eligible for reimbursement in any subsequent year. The amount of any in-kind benefits provided in one year shall
not affect the amount of in-kind benefits provided in any other year. 
 (c) Specified
Employee. Notwithstanding anything in this Agreement to the contrary, if Executive is deemed by the Company at the time of Executive’s Separation from Service to be a “specified employee” for purposes of Section 409A, to the
extent delayed commencement of any portion of the benefits to which Executive is entitled under this Agreement is required in order to avoid a prohibited distribution under Section 409A, such portion of Executive’s benefits shall not be
provided to Executive prior to the earlier of (i) the expiration of the six (6)-month period measured from the date of Executive’s Separation from Service with the Company or (ii) the date of Executive’s death. Upon the first
business day following the expiration of the applicable Section 409A period, all payments deferred pursuant to the preceding sentence shall be paid in a lump sum to Executive (or Executive’s estate or beneficiaries), and any remaining
payments due to Executive under this Agreement shall be paid as otherwise provided herein. 
 11. Withholding. The
Company shall be entitled to withhold from any amounts payable under this Agreement any federal, state, local, or foreign withholding or other taxes or charges which the Company is required to withhold. The Company shall be entitled to rely on an
opinion of counsel if any questions as to the amount or requirement of withholding shall arise. 
 12. Miscellaneous
Provisions. 
 (a) Prior Employment. Executive represents and warrants that Executive’s acceptance of employment
with the Company has not breached, and the performance of Executive’s duties hereunder will not breach, any duty owed by Executive to any prior employer or other person. Executive further represents and warrants to the Company that:
(a) the performance of Executive’s obligations hereunder will not violate any agreement between Executive and any other person, firm, organization, or other entity; (b) Executive is not bound by the terms of any agreement with any
previous employer or other party to refrain from competing, directly or indirectly, with the business of such previous employer or other party that would be violated by Executive entering into this Agreement and/or providing services to the Company
pursuant to the terms of this Agreement; and (c) Executive’s performance of Executive’s duties under this Agreement will not require Executive to, and Executive shall not, rely on in the performance of Executive’s duties or
disclose to the Company or any other person or entity or induce the Company in any way to use or rely on any trade secret or other confidential or proprietary information or material belonging to any previous employer of Executive. 

  
 9 

 (b) Assignment and Successors. The Company shall assign its rights and
obligations under this Agreement to any successor to all or substantially all of the business or the assets of the Company (by merger or otherwise). This Agreement shall be binding upon and inure to the benefit of the Company, Executive, and their
respective successors, assigns, personnel, and legal representatives, executors, administrators, heirs, distributees, devisees, and legatees, as applicable. None of Executive’s rights or obligations may be assigned or transferred by Executive,
other than Executive’s rights to payments hereunder, which may be transferred only by will, operation of law, or as otherwise provided herein. 

(c) Governing Law. This Agreement shall be governed, construed, interpreted, and enforced in accordance with its express terms,
and otherwise in accordance with the substantive laws of the State of California, without giving effect to any principles of conflicts of law, whether of the State of California or any other jurisdiction, and where applicable, the laws of the United
States, that would result in the application of the laws of any other jurisdiction. 
 (d) Validity. The invalidity or
unenforceability of any provision or provisions of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement, which shall remain in full force and effect. 

(e) Amendments; Waivers. This Agreement may not be modified, amended, or terminated except by an instrument in writing signed by
Executive and a duly authorized representative of the Company. By an instrument in writing similarly executed, Executive or a duly authorized officer of the Company, as applicable, may waive compliance by the other Party with any specifically
identified provision of this Agreement that such other Party was or is obligated to comply with or perform; provided, however, that such waiver shall not operate as a waiver of, or estoppel with respect to, any other or subsequent
failure. No failure to exercise and no delay in exercising any right, remedy, or power hereunder shall preclude any other or further exercise of any other right, remedy, or power provided herein or by law or in equity. 

(f) Dispute Resolution. Unless otherwise prohibited by law or specified below, all disputes, claims and causes of action, in law
or equity, arising from or relating to this Agreement or its enforcement, performance, breach, or interpretation shall be resolved solely and exclusively by final and binding arbitration held in San Diego, California, before a single,
mutually-agreed neutral arbitrator, through Judicial Arbitration & Mediation Services (“JAMS”) under the then existing JAMS arbitration rules. The rules may be found online at www.jamsadr.com or upon written request to the
Company. This Section 12(f) is intended to be the exclusive method for resolving any and all claims by the Parties against each other relating to Executive’s employment; provided that Executive will retain the right to file
administrative charges with or seek relief through any government agency of competent jurisdiction, and to participate in any government investigation, including but not limited to (i) claims for workers’ compensation, state disability
insurance or unemployment insurance; (ii) claims for unpaid wages or waiting time penalties brought before the California Division of Labor Standards Enforcement (provided that any appeal from an award or from denial of an award
of wages and/or waiting time penalties shall be arbitrated pursuant to the terms of this paragraph); and (iii) claims for administrative relief from the United States Equal Employment Opportunity Commission and/or the California Department of
Fair Employment and Housing (or any similar agency in any applicable jurisdiction other than California); provided, further, that, except as otherwise provided by law, Executive will not be

  
 10 

 
entitled to obtain any monetary relief through such agencies other than workers’ compensation benefits or unemployment insurance benefits. Further, nothing in this Section 12(f) is
intended to prevent either Party from obtaining injunctive relief in court to prevent irreparable harm pending the conclusion of any such arbitration, including without limitation injunctive relief, in any court of competent jurisdiction pursuant to
California Code of Civil Procedure §1281.8 or any similar statute of an applicable jurisdiction. Seeking any such relief shall not be deemed to be a waiver of such Party’s right to compel arbitration. In resolving any matter submitted to
arbitration, the arbitrator will strictly follow the substantive law applicable to the dispute, claim or controversy and the arbitrator’s authority and jurisdiction will be limited to determining the dispute in conformity with applicable law as
to liability, damages and remedies, to the same extent as if the dispute was determined by a court without a jury. The arbitrator will issue a written decision that contains the essential findings of fact and conclusions of law on which the decision
is based, which may be entered as a judgment in any court of competent jurisdiction. The Company shall pay all costs of arbitration, including without limitation, arbitration administrative fees, arbitrator compensation and expenses, and costs of
any witnesses called by the arbitrator. Unless otherwise ordered by the arbitrator under applicable law, the Company and Executive shall each bear its or his own expenses, such as attorneys’ fees, costs and disbursements. The prevailing party
in any arbitration or other dispute between the parties will be entitled to an award of attorneys’ fees and costs, in addition to any other relief. Each Party warrants that it has had the opportunity to be represented by counsel in the
negotiation and execution of this Agreement, including the attorneys’ fees provision herein. Both Executive and the Company expressly waive his and its right to a jury trial. Executive furthers waives his right to pursue claims against the
Company on a class basis; provided, however, that Executive does not waive his right, to the extent preserved by law, to pursue representative claims against the Company under the California Private Attorney General Act. 

(g) Enforcement. If any provision of this Agreement is held to be illegal, invalid, or unenforceable under present or future
laws, such provision shall be fully severable; this Agreement shall be construed and enforced as if such illegal, invalid, or unenforceable provision had never comprised a portion of this Agreement; and the remaining provisions of this Agreement
shall remain in full force and effect and shall not be affected by the illegal, invalid, or unenforceable provision or by its severance from this Agreement. Furthermore, in lieu of such illegal, invalid, or unenforceable provision there shall be
added automatically as part of this Agreement a provision as similar in terms to such illegal, invalid, or unenforceable provision as may be possible and be legal, valid, and enforceable. 

(h) Entire Agreement. The terms of this Agreement are intended by the Parties to be the final expression of their agreement with
respect to the employment of Executive by the Company and supersede all prior understandings and agreements, whether written or oral, regarding Executive’s employment with the Company. The Parties further intend that this Agreement shall
constitute the complete and exclusive statement of their terms and that no extrinsic evidence whatsoever may be introduced in any judicial, administrative, or other legal proceeding to vary the terms of this Agreement. 

(i) Executive Acknowledgement. Executive acknowledges that Executive has read and understands this Agreement, is fully aware of
its legal effect, has not acted in reliance 

  
 11 

 
upon any representations or promises made by the Company other than those contained in writing herein, and has entered into this Agreement freely based on Executive’s own judgment. 

(j) Counterparts. This Agreement may be executed in several counterparts, each of which shall be deemed to be an original, but
all of which together will constitute one and the same Agreement. Signatures delivered by facsimile shall be deemed effective for all purposes.

TYRA BIOSCIENCES, INC. 

AMENDED AND RESTATED EMPLOYMENT AGREEMENT 

This Amended and Restated Employment Agreement (the “Agreement”) is entered into as of August 18, 2021, by and
between Tyra Biosciences, Inc., a Delaware corporation (the “Company”) and Ronald Swanson (“Executive” and, together with the Company, the “Parties”). This Agreement will be effective upon the
consummation of the Company’s initial public offering (the “IPO”) of its common stock (the “Effective Date”). In the event the IPO does not occur, this Agreement shall be of no force or effect and the Prior Agreement
shall continue. Capitalized terms used herein and not otherwise defined shall have those meanings set forth in Appendix I hereto. 

WHEREAS, the Company and Executive are parties to that certain Employment Agreement dated as of January 16, 2020 (the
“Prior Agreement”); 
 WHEREAS, the Company desires to retain the services of Executive by engaging Executive to
perform services as an employee of the Company under the terms hereof; and 
 WHEREAS, Executive desires to provide services to the
Company on the terms hereof. 
 NOW, THEREFORE, in consideration of the foregoing, and for other good and valuable consideration,
including the respective covenants and agreements set forth below, the receipt and sufficiency of which are hereby acknowledged, the Parties hereto agree as follows: 

1. Employment. 

(a) General. The Company shall continue to employ Executive upon the terms and conditions provided herein effective as of the
Effective Date. 
 (b) Position and Duties. Executive shall serve as the Company’s Chief Scientific Officer, with
responsibilities, duties, and authority usual and customary for such position subject to direction by the Chief Executive Officer (the “CEO”). During Executive’s employment with the Company, Executive shall report directly to
the CEO and agrees promptly and faithfully to comply with all present and future policies, requirements, rules and regulations, and reasonable directions and requests, of the Company in connection with the Company’s business. Executive will at
all times perform all of the duties and obligations required by Executive under this Agreement in a loyal and conscientious manner and to the best of Executive’s ability and experience. 

(c) Performance of Executive’s Duties. During Executive’s employment with the Company, and except for periods of
illness, vacation, Disability, or excused leaves of absence, Executive shall devote Executive’s full time and attention to the business and affairs of the Company pursuant to the general direction of the CEO; provided that nothing herein
shall preclude Executive from, subject to prior consent of the CEO: (i) engaging in additional activities in connection with personal investments and community affairs including service on non-profit
boards of directors; (ii) serving as a member of the board of directors for for-profit organizations that are not competitors of the Company; and (iii) serving as an advisor, or as a member of an
advisory board of organizations that are not competitors of the Company; provided such activities 

  
 1 

 
do not individually or in the aggregate interfere with the performance of Executive’s duties under this Agreement, violate the Company’s standards of conduct then in effect or raise a
conflict under the Company’s conflict of interest policies. 
 2. Term. The period of Executive’s employment
under this Agreement shall continue until Executive’s employment with the Company is terminated. The phrase “Term of Employment” as used in this Agreement shall refer to the entire period of employment of Executive by the
Company. 
 3. Compensation and Related Matters. 

(a) Annual Base Salary. Executive shall receive a base salary at the rate of $410,000 per annum (as may be increased from time
to time, the “Annual Base Salary”), subject to withholdings and deductions, which shall be paid to Executive in accordance with the customary payroll practices and procedures of the Company. Such Annual Base Salary shall be reviewed
by the CEO, and as applicable, the Board of Directors of the Company (the “Board”), not less than annually, and may be increased, but not decreased, in connection with any such review. 

(b) Annual Bonus. Executive shall be eligible to receive a discretionary annual bonus (the “Annual Bonus”)
based on Executive’s achievement of performance objectives in accordance with the terms set forth by the Board. Executive’s target Annual Bonus shall be equal to 40% of Executive’s Annual Base Salary (the “Target
Bonus”). Except as set forth in Section 6, Executive must be employed by the Company on the date of payment of any Annual Bonus to remain eligible to receive such Annual Bonus. Any Annual Bonus earned will be paid at the same time
annual bonuses are paid to other executives of the Company generally, subject to any limitations on payment as set forth in Section 6. Benefits. Executive shall be entitled to participate in such employee and executive benefit plans and
programs as the Company may offer from time to time to provide to its executives, subject to the terms and conditions of such plans. Notwithstanding the foregoing, nothing herein is intended, or shall be construed, to require the Company to
institute or continue any, or any particular, plan, or benefits. 
 (c) Business Expenses. The Company shall reimburse
Executive for all reasonable, documented, out-of-pocket travel and other business expenses incurred by Executive in the performance of Executive’s duties to the
Company in accordance with the Company’s applicable expense reimbursement policies and procedures as are in effect from time to time. 

(d) Vacation; Paid Time Off. Executive will be entitled to vacation or paid time off, in accordance with the Company’s
policy. 
 (e) Equity Awards. Executive shall be eligible to receive grants of equity awards in the Company’s sole
discretion. 
 (f) Indemnification Agreement; Insurance. As an officer of the Company, Executive shall be entitled to enter
into the Company’s standard indemnification agreement. Executive will also be covered under a directors and officers liability insurance policy paid for by the Company for so long as Executive serves as an officer of the Company.

 4. Acceleration of Equity Awards Upon a Change in Control.
Notwithstanding anything herein to the contrary, in the event of a Change in Control, the vesting of Executive’s then outstanding options, restricted stock and other equity awards covering shares of the Company’s common stock
(collectively, “Equity Awards”) shall accelerate as of immediately prior to such Change in Control with respect to fifty percent (50%) of the unvested shares of Company common stock subject to such Equity Awards. The remaining fifty
percent (50%) of the unvested shares of Company common stock subject to Executive’s Equity Awards shall continue to vest at the same rate as immediately prior to the Change in Control, subject to Executive’s continued employment with the
Company or its successor through the applicable vesting date. Any portion of Executive’s Equity Awards that remains unvested as of the first anniversary of the Change in Control shall thereupon vest in full, subject to Executive’s
continued employment with the Company or its successor through such first anniversary. Notwithstanding the foregoing and for the avoidance of doubt, any shares subject to Equity Awards that do not accelerate immediately prior to the Change in
Control in accordance with the foregoing shall be subject to accelerated vesting in accordance with Section 6(d)(iii) below. 

5. Termination. 

(a) At-Will Employment. The Company and Executive acknowledge that Executive’s
employment is and shall continue to be at-will, as defined under applicable law. This means that it is not for any specified period of time and can be terminated by Executive or by the Company at any time,
with or without advance notice, and for any or no particular reason or cause. It also means that Executive’s job duties, title, and responsibility and reporting level, work schedule, compensation, and benefits, as well as the Company’s
personnel policies and procedures, may be changed with prospective effect, with or without notice, at any time in the sole discretion of the Company (subject to any ramification such changes may have under Section 6 of this Agreement). This “at-will” nature of Executive’s employment shall remain unchanged during Executive’s tenure as an employee and may not be changed, except in an express writing signed by Executive and the CEO. If
Executive’s employment terminates for any lawful reason, Executive shall not be entitled to any payments, benefits, Equity Awards or other compensation other than as provided in this Agreement. 

(b) Notice of Termination. During the Term of Employment, any termination of Executive’s employment by the Company or by
Executive (other than by reason of death) shall be communicated by written notice (a “Notice of Termination”) from one Party hereto to the other Party hereto (i) indicating the specific termination provision in this Agreement
relied upon, if any, (ii) setting forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of Executive’s employment under the provision so indicated and (iii) specifying the date of the
termination of Executive’s employment with the Company (the “Date of Termination”). The failure by the Company to set forth in the Notice of Termination all of the facts and circumstances which contribute to a showing of Cause
shall not waive any right of the Company hereunder or preclude the Company from asserting such fact or circumstance in enforcing its rights hereunder. The failure by Executive to set forth in the Notice of Termination all of the facts and
circumstances which contribute to a showing of Good Reason shall not waive any right of Executive hereunder or preclude Executive from asserting such fact or circumstance in enforcing Executive’s rights hereunder. 

  
 3 

 (c) Deemed Resignation. Upon termination of Executive’s employment with
the Company for any reason, Executive shall be deemed to have resigned from all offices and board memberships, if any, then held with the Company or any of its affiliates, and, at the Company’s request, Executive shall execute such documents as
are necessary or desirable to effectuate such resignations. 
 6. Consequences of Termination. 

(a) Release. In the event Executive’s employment with the Company terminates pursuant to Section 5, then Executive
shall be entitled to the applicable payments and benefits set forth below subject to, in the case of a termination described in Section 6(c) or 6(d), Executive delivering to the Company a waiver and release of claims agreement in standard
reasonable form approved by the Company that becomes effective and irrevocable in accordance with Section 7 hereof (a “Release”). 

(b) Payments upon Termination by the Company for Cause or by Executive Without Good Reason. Upon a termination of
Executive’s employment with the Company at any time for Cause or by Executive without Good Reason, Executive (or Executive’s estate or legal representative, as applicable) shall be entitled to receive, within thirty (30) days of the
effective date of termination of employment with the Company (whether such termination of employment is effected by the Company or Executive) (or such earlier date as may be required by applicable law): (i) any portion of Executive’s Annual
Base Salary earned through Executive’s Date of Termination not theretofore paid; (ii) any reimbursement of expenses owed to Executive under Section 3(e) above; and (iii) any accrued but unused vacation or paid time-off owed to Executive ((i)-(iii) defined as the “Accrued Obligations”). In the event Executive is terminated by the Company for Cause, Executive shall forfeit, effective as of the date
Executive engages in such conduct giving rise to his termination for Cause, all unexercised, unearned and/or unpaid Equity Awards, including without limitation, Equity Awards earned but not yet paid, all unpaid dividends and dividend equivalents and
all interest, if any, accrued on the foregoing. 
 (c) Severance Payments upon Involuntary Termination Outside a Change in Control
Period. If, outside a Change in Control Period, Executive’s employment is terminated due to an Involuntary Termination, the Company shall provide the following payments and benefits: 

(i) the Accrued Obligations; 

(ii) an amount in cash equal to (A) twelve months of Executive’s Annual Base Salary plus (B) Executive’s Target
Bonus for the calendar year in which such Involuntary Termination occurs, pro-rated based on the total number of days elapsed in the calendar year as of Executive’s Date of Termination; 

(iii) fifty percent (50%) of the unvested Equity Awards held by the Executive as of the Date of Termination will become fully vested
and, if applicable, exercisable, and all restrictions and rights of repurchase thereon shall lapse with respect to all of the shares of the Company’s common stock subject thereto; and 

(iv) during the period commencing on the Date of Termination and ending on the twelve-month anniversary thereof or, if earlier, the
date on which Executive becomes 

  
 4 

 
eligible for comparable replacement coverage under a subsequent employer’s group health plan, subject to Executive’s valid election to continue healthcare coverage under
Section 4980B of the Internal Revenue Code of 1986, as amended (the “Code”) and the regulations thereunder (“COBRA”), the Company shall, in its sole discretion, either (A) continue to provide to Executive
and Executive’s dependents, at the Company’s sole expense, or (B) reimburse Executive and Executive’s dependents for the cost of, in either case, coverage under its group health plan (if any) at the same coverage levels in effect
on the Date of Termination (“Benefits Coverage”); provided, however, that if (1) any plan pursuant to which such benefits are provided is not, or ceases prior to the expiration of the continuation coverage period
to be, exempt from the application of Section 409A under Treasury Regulation Section 1.409A-1(a)(5), (2) the Company is otherwise unable to continue to cover Executive or Executive’s dependents
under its group health plans or (3) the Company cannot provide the benefit without violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), then, in any such case, the cash amount necessary
to maintain the Benefits Coverage shall thereafter be paid to Executive in substantially equal taxable monthly installments over the COBRA continuation period (or remaining portion thereof). 

(d) Severance Payments upon Involuntary Termination During a Change in Control Period. If, during a Change in Control Period,
Executive’s employment is terminated due to an Involuntary Termination, the Company shall provide the following payments and benefits: 

(i) the Accrued Obligations; 

(ii) an amount in cash equal to (A) eighteen months of Executive’s Annual Base Salary plus (B) one hundred percent
(100%) of Executive’s Target Bonus for the calendar year in which such Involuntary Termination occurs (for the avoidance of doubt, if (x) Executive incurred an Involuntary Termination prior to a Change in Control that qualifies Executive
for severance payments under Section 6(c)(ii); and (y) a Change in Control occurs within the three (3)-month period following Executive’s Involuntary Termination that qualifies Executive for the increased benefits under this
Section 6(d)(ii), then Executive shall be entitled to a lump-sum payment of the amount calculated under this Section 6(d)(ii), less any amount already paid under Section 6(c)(ii)); 

(iii) one hundred percent (100%) of all unvested Equity Awards held by Executive as of the Date of Termination, will become fully
vested and, if applicable, exercisable, and all restrictions and rights of repurchase thereon shall lapse with respect to all of the shares of the Company’s common stock subject thereto effective on the later of (x) the Date of Termination
or (y) the date of the Change in Control (for the avoidance of doubt, if Executive’s Involuntary Termination occurs prior to a Change in Control, then any unvested portion of Executive’s outstanding Equity Awards will remain
outstanding for three (3) months or the occurrence of a Change in Control (whichever is earlier) so that any vesting acceleration benefits provided under this clause (iii) can be provided if a Change in Control occurs within three
(3) months following such termination (provided that in no event will the Equity Awards remain outstanding beyond the Equity Award’s maximum term or expiration date. In such case, if no Change in Control occurs within three (3) months
following Executive’s termination, any unvested portion of Executive’s Equity Awards automatically will be forfeited without having vested; and 

  
 5 

 (iv) during the period commencing on the Date of Termination and ending on the first
anniversary thereof or, if earlier, the date on which Executive becomes eligible for comparable replacement coverage under a subsequent employer’s group health plan, subject to Executive’s valid election to continue healthcare coverage
under COBRA, the Company shall, in its sole discretion, either (A) continue to provide to Executive and Executive’s dependents, at the Company’s sole expense, or (B) reimburse Executive and Executive’s dependents for the
cost of, in either case, the Benefits Coverage; provided, however, that if (1) any plan pursuant to which such benefits are provided is not, or ceases prior to the expiration of the continuation coverage period to be, exempt from
the application of Section 409A under Treasury Regulation Section 1.409A-1(a)(5), (2) the Company is otherwise unable to continue to cover Executive or Executive’s dependents under its group
health plans or (3) the Company cannot provide the benefit without violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), then, in any such case, the cash amount necessary to maintain the
Benefits Coverage shall thereafter be paid to Executive in substantially equal taxable monthly installments over the COBRA continuation period (or remaining portion thereof). 

(e) No Other Severance. The provisions of this Section 6 shall supersede in their entirety any severance payment provisions
in any severance plan, policy, program, or other arrangement maintained by the Company except for such additional benefits otherwise approved by the Board or Compensation Committee of the Board after the date hereof. 

(f) No Requirement to Mitigate; Survival. Executive shall not be required to mitigate the amount of any payment provided for
under this Agreement by seeking other employment or in any other manner. Notwithstanding anything to the contrary in this Agreement, the termination of Executive’s employment shall not impair the rights or obligations of any Party. 

7. Release and Payment Timing. 

(a) Release. Notwithstanding anything to the contrary in this Agreement, any payments or other benefits due under this Agreement
under Sections 6(c) and 6(d) as a result of Executive’s termination of employment (other than the Accrued Obligations) are subject to Executive’s execution and delivery of a Release, as follows: (i) the Company shall deliver the
Release to Executive within five (5) days following Executive’s Date of Termination, and the Company’s failure to deliver a Release prior to the expiration of such five (5) day period shall constitute a waiver of any requirement
to execute a Release, (ii) if Executive fails to execute the Release on or prior to the Release Expiration Date (as defined below) or timely revokes Executive’s acceptance of the Release thereafter, Executive shall not be entitled to any
payments or benefits otherwise conditioned on the Release, and (iii) if the Release does not become effective and irrevocable no later than sixty (60) days following the Date of Termination (such deadline, the “Release
Deadline”), Executive shall not be entitled to any payments or benefits otherwise conditioned on the Release. For purposes of this Section 7, “Release Expiration Date” shall mean the date that is twenty-one (21) days following the date upon which the Company timely delivers the Release to Executive, or, in the event that Executive’s termination of employment is “in connection with an exit
incentive or other employment termination program” (as such phrase is defined in the Age Discrimination in Employment Act of 1967), the date that is forty-five (45) days following such delivery date. 

  
 6 

 (b) Payment Timing. The payments due under Sections 6(c)(ii) and 6(d)(ii) of
this Agreement as a result of Executive’s termination of employment shall be paid in a lump sum on the date that is sixty (60) days following the Date of Termination; provided, however, that, in the event of Executive’s Involuntary
Termination during the Change in Control Period but prior to a Change in Control, any additional amount payable to Executive under Section 6(d)(ii) in excess of the amounts payable to such Executive under Section 6(c)(ii) shall be paid in
a lump sum on the date that is sixty (60) days following the later of (x) the Date of Termination, or (y) the date of the Change in Control. 

8. Non-Solicitation of Employees. For a period of one (1) year following
Executive’s Date of Termination, Executive shall not, either directly or indirectly (a) solicit for employment through any individual, corporation, firm, or other business, any employees, consultants, independent contractors, or other
service providers of the Company or any of its affiliates, or (b) solicit any employee, consultant or other service provider of the Company or any of its affiliates to leave the employment or consulting of or cease providing services to the
Company or any of its affiliates; provided, however, that the foregoing clauses (a) and (b) shall not apply to inbound inquiries or any general advertisement or solicitation (or any hiring pursuant to such advertisement or
solicitation) that is not specifically targeted to such employees, consultants or other service providers. 
 9. Golden
Parachute Excise Tax. 
 (a) Best Pay. Any provision of this Agreement to the contrary notwithstanding, if any payment
or benefit Executive would receive from the Company pursuant to this Agreement or otherwise (“Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code and (ii) but
for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment will be equal to the Reduced Amount (as defined below). The “Reduced Amount” will be
either (A) the largest portion of the Payment that would result in no portion of the Payment (after reduction) being subject to the Excise Tax or (B) the entire Payment, whichever amount 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, net of the maximum reduction in federal income taxes which could be obtained from a deduction of such state and local taxes),
results in Executive’ s 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 (A) of the preceding sentence, the reduction shall occur in the manner (the “Reduction Method”) that results in the
greatest economic benefit for Executive. 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”). Notwithstanding the foregoing,
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 (as defined below) 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, shall be modified so as to avoid the imposition of taxes pursuant to Section 409A as follows: (1) as a first priority, the modification shall preserve to
the greatest extent possible, the greatest economic benefit for Executive as determined on an after-tax basis; (2) as a second priority, Payments that are contingent on future events (e.g., being
terminated without cause), shall be reduced (or eliminated) before Payments that are not contingent on future events; and (3) as a third priority, Payments that 

  
 7 

 
are “deferred compensation” within the meaning of Section 409A shall be reduced (or eliminated) before Payments that are not deferred compensation within the meaning of
Section 409A. 
 (a) Accounting Firm. All determinations regarding the application of this Section 9 shall be made
by an independent accounting firm or consulting group with nationally recognized standing and substantial expertise and experience in performing calculations regarding the applicability of Section 280G of the Code and the Excise Tax retained by
the Company prior to the date of the applicable change in ownership or control (the “280G Firm”). The Company will bear all expenses with respect to the determinations by the 280G Firm required to be made hereunder. The 280G Firm
engaged to make the determinations hereunder will provide its calculations, together with detailed supporting documentation, to the Company within thirty (30) days before the consummation of a Change in Control (if requested at that time by the
Company) or such other time as requested by the Company. If the 280G Firm determines that no Excise Tax is payable with respect to a Payment, either before or after the application of the Reduced Amount, it will furnish the Company with
documentation reasonably acceptable to the Company that no Excise Tax will be imposed with respect to such Payment. Any good faith determinations of the 280G Firm made hereunder will be final, binding and conclusive upon the Company and Executive.

 10. Section 409A. 

(a) General. The intent of the Parties is that the payments and benefits under this Agreement comply with or be exempt from
Section 409A of the Code and the Department of Treasury regulations and other interpretive guidance issued thereunder, including without limitation any such regulations or other guidance that may be issued after the Effective Date,
(“Section 409A”) and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted to be in compliance therewith. If Executive notifies the Company that Executive has received advice of tax
counsel of a national reputation with expertise in Section 409A that any provision of this Agreement would cause Executive to incur any additional tax or interest under Section 409A (with specificity as to the reason therefor) or the
Company independently makes such determination, the Company and Executive shall take commercially reasonable efforts to reform such provision to try to comply with or be exempt from Section 409A through good faith modifications to the minimum
extent reasonably appropriate to conform with Section 409A, provided that any such modifications shall not increase the cost or liability to the Company. To the extent that any provision hereof is modified in order to comply with or be
exempt from Section 409A, such modification shall be made in good faith and shall, to the maximum extent reasonably possible, maintain the original intent and economic benefit to Executive and the Company of the applicable provision without
violating the provisions of Section 409A. 
 (b) Separation from Service. Notwithstanding any provision to the contrary
in this Agreement: (i) no amount that constitutes “deferred compensation” under Section 409A shall be payable pursuant to Section 6(c) or Section 6(d) above unless the termination of Executive’s employment
constitutes a “separation from service” within the meaning of Section 1.409A-1(h) of the Department of Treasury Regulations (“Separation from Service”); (ii) for purposes of
Section 409A, Executive’s right to receive installment payments shall be treated as a right to receive a series of separate and distinct payments; and (iii) to the extent that any reimbursement of expenses or in-kind benefits constitutes “deferred compensation” under Section 409A, such reimbursement or benefit shall be provided no later than December 31st of the year following the year in which

  
 8 

 
the expense was incurred. The amount of expenses reimbursed in one year shall not affect the amount eligible for reimbursement in any subsequent year. The amount of any in-kind benefits provided in one year shall not affect the amount of in-kind benefits provided in any other year. 

(c) Specified Employee. Notwithstanding anything in this Agreement to the contrary, if Executive is deemed by the Company at the
time of Executive’s Separation from Service to be a “specified employee” for purposes of Section 409A, to the extent delayed commencement of any portion of the benefits to which Executive is entitled under this Agreement is
required in order to avoid a prohibited distribution under Section 409A, such portion of Executive’s benefits shall not be provided to Executive prior to the earlier of (i) the expiration of the six (6)-month period measured from the
date of Executive’s Separation from Service with the Company or (ii) the date of Executive’s death. Upon the first business day following the expiration of the applicable Section 409A period, all payments deferred pursuant to the
preceding sentence shall be paid in a lump sum to Executive (or Executive’s estate or beneficiaries), and any remaining payments due to Executive under this Agreement shall be paid as otherwise provided herein. 

11. Withholding. The Company shall be entitled to withhold from any amounts payable under this Agreement any federal,
state, local, or foreign withholding or other taxes or charges which the Company is required to withhold. The Company shall be entitled to rely on an opinion of counsel if any questions as to the amount or requirement of withholding shall arise.

 12. Miscellaneous Provisions. 

(a) Prior Employment. Executive represents and warrants that Executive’s acceptance of employment with the Company has not
breached, and the performance of Executive’s duties hereunder will not breach, any duty owed by Executive to any prior employer or other person. Executive further represents and warrants to the Company that: (a) the performance of
Executive’s obligations hereunder will not violate any agreement between Executive and any other person, firm, organization, or other entity; (b) Executive is not bound by the terms of any agreement with any previous employer or other
party to refrain from competing, directly or indirectly, with the business of such previous employer or other party that would be violated by Executive entering into this Agreement and/or providing services to the Company pursuant to the terms of
this Agreement; and (c) Executive’s performance of Executive’s duties under this Agreement will not require Executive to, and Executive shall not, rely on in the performance of Executive’s duties or disclose to the Company or any
other person or entity or induce the Company in any way to use or rely on any trade secret or other confidential or proprietary information or material belonging to any previous employer of Executive. 

(b) Assignment and Successors. The Company shall assign its rights and obligations under this Agreement to any successor to all
or substantially all of the business or the assets of the Company (by merger or otherwise). This Agreement shall be binding upon and inure to the benefit of the Company, Executive, and their respective successors, assigns, personnel, and legal
representatives, executors, administrators, heirs, distributees, devisees, and legatees, as applicable. None of Executive’s rights or obligations may be assigned or transferred by Executive, other than Executive’s rights to payments
hereunder, which may be transferred only by will, operation of law, or as otherwise provided herein. 

  
 9 

 (c) Governing Law. This Agreement shall be governed, construed, interpreted,
and enforced in accordance with its express terms, and otherwise in accordance with the substantive laws of the State of California, without giving effect to any principles of conflicts of law, whether of the State of California or any other
jurisdiction, and where applicable, the laws of the United States, that would result in the application of the laws of any other jurisdiction. 

(d) Validity. The invalidity or unenforceability of any provision or provisions of this Agreement shall not affect the validity
or enforceability of any other provision of this Agreement, which shall remain in full force and effect. 
 (e) Amendments;
Waivers. This Agreement may not be modified, amended, or terminated except by an instrument in writing signed by Executive and a duly authorized representative of the Company. By an instrument in writing similarly executed, Executive or a duly
authorized officer of the Company, as applicable, may waive compliance by the other Party with any specifically identified provision of this Agreement that such other Party was or is obligated to comply with or perform; provided,
however, that such waiver shall not operate as a waiver of, or estoppel with respect to, any other or subsequent failure. No failure to exercise and no delay in exercising any right, remedy, or power hereunder shall preclude any other or
further exercise of any other right, remedy, or power provided herein or by law or in equity. 
 (f) Dispute Resolution.
Unless otherwise prohibited by law or specified below, all disputes, claims and causes of action, in law or equity, arising from or relating to this Agreement or its enforcement, performance, breach, or interpretation shall be resolved solely and
exclusively by final and binding arbitration held in San Diego, California, before a single, mutually-agreed neutral arbitrator, through Judicial Arbitration & Mediation Services (“JAMS”) under the then existing JAMS
arbitration rules. The rules may be found online at www.jamsadr.com or upon written request to the Company. This Section 12(f) is intended to be the exclusive method for resolving any and all claims by the Parties against each other relating to
Executive’s employment; provided that Executive will retain the right to file administrative charges with or seek relief through any government agency of competent jurisdiction, and to participate in any government investigation,
including but not limited to (i) claims for workers’ compensation, state disability insurance or unemployment insurance; (ii) claims for unpaid wages or waiting time penalties brought before the California Division of Labor Standards
Enforcement (provided that any appeal from an award or from denial of an award of wages and/or waiting time penalties shall be arbitrated pursuant to the terms of this paragraph); and (iii) claims for administrative relief from
the United States Equal Employment Opportunity Commission and/or the California Department of Fair Employment and Housing (or any similar agency in any applicable jurisdiction other than California); provided, further, that, except as
otherwise provided by law, Executive will not be entitled to obtain any monetary relief through such agencies other than workers’ compensation benefits or unemployment insurance benefits. Further, nothing in this Section 12(f) is intended
to prevent either Party from obtaining injunctive relief in court to prevent irreparable harm pending the conclusion of any such arbitration, including without limitation injunctive relief, in any court of competent jurisdiction pursuant to
California Code of Civil Procedure §1281.8 or any similar statute of an applicable jurisdiction. Seeking any such relief shall not be deemed to be a waiver of such Party’s right to compel arbitration. In resolving any matter submitted to
arbitration, the arbitrator will strictly follow the substantive law applicable to the dispute, claim or controversy and the arbitrator’s authority and jurisdiction will be limited to determining the dispute in conformity with applicable law as
to liability, damages and remedies, to the same extent as if the 

  
 10 

 
dispute was determined by a court without a jury. The arbitrator will issue a written decision that contains the essential findings of fact and conclusions of law on which the decision is based,
which may be entered as a judgment in any court of competent jurisdiction. The Company shall pay all costs of arbitration, including without limitation, arbitration administrative fees, arbitrator compensation and expenses, and costs of any
witnesses called by the arbitrator. Unless otherwise ordered by the arbitrator under applicable law, the Company and Executive shall each bear its or his own expenses, such as attorneys’ fees, costs and disbursements. The prevailing party in
any arbitration or other dispute between the parties will be entitled to an award of attorneys’ fees and costs, in addition to any other relief. Each Party warrants that it has had the opportunity to be represented by counsel in the negotiation
and execution of this Agreement, including the attorneys’ fees provision herein. Both Executive and the Company expressly waive his and its right to a jury trial. Executive furthers waives his right to pursue claims against the Company on a
class basis; provided, however, that Executive does not waive his right, to the extent preserved by law, to pursue representative claims against the Company under the California Private Attorney General Act. 

(g) Enforcement. If any provision of this Agreement is held to be illegal, invalid, or unenforceable under present or future
laws, such provision shall be fully severable; this Agreement shall be construed and enforced as if such illegal, invalid, or unenforceable provision had never comprised a portion of this Agreement; and the remaining provisions of this Agreement
shall remain in full force and effect and shall not be affected by the illegal, invalid, or unenforceable provision or by its severance from this Agreement. Furthermore, in lieu of such illegal, invalid, or unenforceable provision there shall be
added automatically as part of this Agreement a provision as similar in terms to such illegal, invalid, or unenforceable provision as may be possible and be legal, valid, and enforceable. 

(h) Entire Agreement. The terms of this Agreement are intended by the Parties to be the final expression of their
agreement with respect to the employment of Executive by the Company and supersede all prior understandings and agreements, whether written or oral, regarding Executive’s employment with the Company. The Parties further intend that this
Agreement shall constitute the complete and exclusive statement of their terms and that no extrinsic evidence whatsoever may be introduced in any judicial, administrative, or other legal proceeding to vary the terms of this Agreement. 

(i) Executive Acknowledgement. Executive acknowledges that Executive has read and understands this Agreement, is fully aware of
its legal effect, has not acted in reliance upon any representations or promises made by the Company other than those contained in writing herein, and has entered into this Agreement freely based on Executive’s own judgment. 

(j) Counterparts. This Agreement may be executed in several counterparts, each of which shall be deemed to be an original, but
all of which together will constitute one and the same Agreement. Signatures delivered by facsimile shall be deemed effective for all purposes.
