THIS EXECUTIVE EMPLOYMENT AGREEMENT (this “Agreement”) is entered into as of January 1, 2017, (the “Effective
Date”) by and between SutroVax, Inc. (the “Company”), and Elaine Sun (“Executive”) (collectively referred to as the “Parties” or individually referred to as a “Party”).

 RECITALS 
 WHEREAS,
Executive was presented with an offer letter to serve as Chief Financial Officer with the Company, dated November 30, 2016 (“Offer Letter”); 

WHEREAS, Executive and the Company desire to enter into a more detailed agreement embodying the terms of such employment and as set forth in

AGREEMENT 
 NOW,
THEREFORE, in consideration of the premises and mutual covenants herein and for other good and valuable consideration, the Parties agree as follows: 

1. Duties and Scope of Employment. 

(a) Positions and Duties. As of the Effective Date, Executive will serve as the Chief Financial Officer of the Company. Executive will
render such business and professional services in the performance of her duties, consistent with Executive’s position within the Company, as shall reasonably be assigned to her by the President & CEO. The period of Executive’s at-will employment under the terms of this Agreement is referred to herein as the “Employment Term.” 

(b) Obligations. During the Employment Term, Executive will perform her duties faithfully and to the best of her ability and will
devote her full business efforts and time to the Company. For the duration of the Employment Term, Executive agrees not to actively engage in any other employment, occupation or consulting activity for any direct or indirect remuneration without the
prior approval of the Company’s Board of Directors (the “Board”); provided, however, that Executive shall be permitted to serve as a member of the Board of Directors of up to two other entities (one of which may be a
privately held company) so long as such service does not create a conflict of interest with the Company. The service by Executive on the Board of Directors of more than two other entities shall require the prior approval of the Board. 

2. At-Will Employment. Subject to Sections 7, 8, and 9 below, the parties agree that
Executive’s employment with the Company will be “at-will” employment and may be terminated at any time with or without cause or notice, for any reason or no reason. Executive understands and
agrees that neither her job performance nor promotions, commendations, bonuses or the like from the Company give rise to or in any way serve as the basis for modification, amendment, or extension, by implication or otherwise, of her employment with
the Company.

 3. Compensation. 

(a) Base Salary. During the Employment Term, the Company will pay Executive as compensation for her services a base salary at a rate of
$320,000 per annum, as modified from time to time at the discretion of the Board or a duly constituted committee of the Board (the “Base Salary”). The Base Salary will be paid in regular installments in accordance with the
Company’s normal payroll practices (subject to required withholding). Any modification in Base Salary (together with the then existing Base Salary) shall serve as the “Base Salary” for future employment under this Agreement. The first
and last payment will be adjusted, if necessary, to reflect a commencement or termination date other than the first or last working day of a pay period. 

(b) Bonus. Executive is also eligible to earn an annual bonus for each fiscal year of the Company with a value up to 30% of
Executive’s Base Salary (“Annual Bonus”). The actual amount of the Annual Bonus will be determined in the sole discretion of the Board based on mutually agreed upon measures of Company performance. Subject to Sections 7 and 9
below, Executive must remain employed through the last day of each fiscal year to be eligible to earn a bonus. Any Annual Bonus that is earned will be paid no later than 60 days after the end of the fiscal year to which it pertains. 

(c) Stock Option. The Parties acknowledges that, the Company agreed to grant the Executive an option to purchase from the Company
230,000 shares of Common Stock, at an exercise price of $0.76 per share (the “Option”) for an aggregate purchase price of $174,800. This Option shall be exercisable, in whole or in part, according to the following vesting schedule:
Twenty-five percent (25%) of the Shares subject to the Option shall vest on the one (1) year anniversary of the date on which Executive commence service with the Company (the “Vesting Commencement Date”), and one forth-eighth
(1/48th) of the Shares subject to the Option shall vest each month thereafter on the same day of the month as the Vesting Commencement Date, subject to Executive continuing to be a Service
Provider through each such date. Notwithstanding anything to the contrary in any stock option agreement evidencing the Option, the Option shall remain exercisable for a period of three months following Executive’s termination or resignation of
service, except in the event of the termination of Executive’s employment by reason of death or Disability, in which event the Option shall remain exercisable for a period of 12 months following Executive’s termination of service. 

(d) Executive will be eligible to receive awards of stock options, restricted stock or other equity awards pursuant to any plans or
arrangements the Company may have in effect from time to time. The Board or a committee of the Board shall determine in its discretion whether Executive shall be granted any such equity awards and the terms of any such award in accordance with the
terms of any applicable plan or arrangement that may be in effect from time to time. 
 4. Employee Benefits. During the Employment
Term, Executive will be eligible to participate in the employee benefit plans currently and hereafter maintained by the Company of general applicability to other senior executives of the Company. As of the Effective Date, the Company offers direct
payment of monthly health care coverage, including medical, dental, and vision for the employee and his/her immediate family. The Company reserves the right to cancel or change the benefit plans and programs it offers to its employees at any time.

 5. Vacation. Executive will be eligible for paid vacation in accordance with the Company’s vacation policy, which shall be
taken subject to the demands of the Company’s business and Executive’s obligations as an employee of the Company with a substantial degree of responsibility. 

6. Business Expenses. During the Employment Term, the Company will reimburse Executive for reasonable business travel, entertainment or
other business expenses incurred by Executive in the furtherance of or in connection with the performance of Executive’s duties hereunder, in accordance with the Company’s expense reimbursement policy as in effect from time to time.

 8. Involuntary Termination for Cause; Resignation Without Good Reason. 

(a) Effectiveness. Notwithstanding any other provision of this Agreement, the Company may terminate Executive’s employment at any
time for Cause or Executive may resign from her employment with the Company at any time for any reason. Termination for Cause, or Executive’s resignation without Good Reason, shall be effective on the date either Party gives notice to the other

to be reimbursed pursuant to Section 6 above, but for which he has not yet been reimbursed; (E) reimbursement for the payments Executive makes for COBRA coverage for the earlier of
(A) a period of twelve (12) months and (B) such time as Executive obtains new employment in connection with which health insurance is offered, provided Executive timely elects and pays for COBRA coverage (COBRA reimbursements shall be

or benefits of any kind, unless required by law or pursuant to any written Company plans or policies, as then in effect. 
 (b)
Conditions Precedent. Any severance payments contemplated by Section 9(a) above are conditional on Executive: (i) continuing to comply with the terms of this Agreement and the Confidential Information Agreement; and
(ii) signing and not revoking a separation agreement and release of claims in a form reasonably satisfactory to the Company and provided that such separation agreement and release of claims becomes effective and irrevocable no later than sixty
(60) days following the termination date or such earlier date required by the release (such deadline, the “Release Deadline”). If the release of claims does not become effective by the Release Deadline, Executive will forfeit
any rights to severance or benefits under this Section 9 or elsewhere in this Agreement. Any severance payments or other benefits under this Agreement that would be considered Deferred Compensation Separation Benefits (as defined in
Section 26) will be paid on, or, in the case of installments, will not commence until, the sixtieth (60th) day following Executive’s separation from service, or, if later, such time as required by Section 26(b). Except as required by
Section 26(b), any installment payments that would have been made to Employee during the sixty (60) day period immediately following Executive’s separation from service but for the preceding sentence will be paid to Executive on the
sixtieth (60th) day following Executive’s separation from service and the remaining payments will be made as provided in this Agreement, unless subject to the 6-month payment delay described herein. Any
severance payments under this Agreement that would not be considered Deferred Compensation Separation Benefits will be paid on, or, in the case of installments, will not commence until, the first payroll date that occurs on or after the date the
Release becomes effective and any installment payments that would have been made to Executive during the period prior to the date the Release becomes effective following Executive’s separation from service but for the preceding sentence will be
paid to Executive on the first payroll date that occurs on or after the date the Release becomes effective. Notwithstanding the foregoing, this Section 9(b) shall not limit Executive’s ability to obtain expense reimbursements under
Section 6 or any other compensation or benefits otherwise required by law or in accordance with written Company plans or policies, as then in effect. 

10. Definitions. 
 (a)
Cause. For purposes of this Agreement, “Cause” shall mean: (i) Executive’s continued failure to substantially perform the material duties and obligations under this Agreement (for reasons other than death or
Disability), which failure, if curable within the discretion of the Company, is not cured to the reasonable satisfaction of the Company within thirty (30) days after receipt of written notice from the Company of such failure;
(ii) Executive’s failure or refusal to comply with the written policies, standards and regulations established by the Company which failure, if curable in the discretion of the Company, is not cured to the reasonable satisfaction of the
Company within thirty (30) days after receipt of written notice of such failure from the Company; (iii) any act of fraud, embezzlement or material misrepresentation committed by Executive that benefits Executive at the expense of the
Company or that otherwise materially and adversely affects the Company; (iv) the Executive’s violation of a federal or state law or regulation applicable to the Company’s business; (v) the Executive’s violation of, or a plea
of nolo contendre or guilty to, a felony under the laws of the United States or any state; or (vi) the Executive’s material breach of the terms of this Agreement or the Confidential Information Agreement (defined below). 

(b) Change of Control. For purposes of this Agreement, “Change of Control” shall mean: 

  
 - 4 - 













 (i) the acquisition of the Company by another entity by means of any transaction or series
of related transactions (including, without limitation, any reorganization, merger or consolidation or stock transfer, but excluding any such transaction effected primarily for the purpose of changing the domicile of the Company), unless the
Company’s stockholders of record immediately prior to such transaction or series of related transactions hold, immediately after such transaction or series of related transactions, at least 50% of the voting power of the surviving or acquiring
entity (provided that the sale by the Company of its securities for the purposes of raising additional funds shall not constitute a Change of Control hereunder); or 

(ii) a sale of all or substantially all of the assets of the Company. Notwithstanding the foregoing, a transaction will not be deemed a
Change of Control unless the transaction qualifies as a change in control event within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and the final regulations and any other guidance
promulgated thereunder (“Section 409A”). Further and for the avoidance of doubt, a transaction will not constitute a Change of Control if: (i) its sole purpose is to change the state of the Company’s
incorporation, or (ii) its sole purpose is to create a holding company that will be owned in substantially the same proportions by the persons who held the Company’s securities immediately before such transaction. 

(c) Good Reason. For purposes of this Agreement, “Good Reason” means Executive’s resignation within thirty
(30) days following the expiration of any Company cure period (discussed below) following the occurrence of one or more of the following, without Executive’s consent: (i) the assignment to Executive of any duties, or the reduction of
Executive’s duties, either of which results in a material diminution of Executive’s authority, duties, or responsibilities with the Company in effect immediately prior to such change, or the removal of Executive from her position and
responsibilities as Chief Financial Officer (unless it is in connection with a promotion or increase in her duties and responsibilities); provided, however, that a reduction in duties, position or responsibilities solely by virtue of the Company
being acquired and made part of a larger entity, whether as a subsidiary, business unit or otherwise (as, for example, when the Chief Financial Officer of the Company remains the Chief Financial Officer of the Company following a Change in Control
where the Company becomes a wholly owned subsidiary of the acquiror, but is not made the Chief Financial Officer of the acquiring corporation) will not constitute “Good Reason”; (ii) a material reduction of Executive’s Base
Salary (the reduction must be more than ten percent of Executive’s Base Salary in any one year in order to be considered “Good Reason”); and (iii) the relocation of Executive’s work location to a facility that is more
than thirty-five (35) miles from Executive’s current work location. Executive will not resign for Good Reason without first providing the Company with written notice of the acts or omissions constituting the grounds for “Good
Reason” within ninety (90) days of the initial existence of the grounds for “Good Reason” and a reasonable cure period of not less than thirty (30) days following the date of such notice. 

(d) Disability. For purposes of this Agreement, “Disability” means that Executive, at the time notice is given, has
been unable to substantially perform Executive’s duties under this Agreement for not less than one-hundred and twenty (120) work days within a twelve (12) consecutive month period as a result of
Executive’s incapacity due to a physical or mental condition and, if reasonable accommodation is required by law, after any reasonable accommodation. 

11. Acceleration of Shares; Change of Control. 

In the event of a Change of Control that occurs prior to the termination of Executive’s employment, if within one (1) year after
such Change of Control (a) the Company terminates Executive’s employment without Cause, or (ii) Executive resigns from employment for Good Reason, upon such termination Executive shall be deemed to have vested in 100% of the total
shares subject to the Stock Option Agreement. All shares and options shall continue to be subject to all other terms of the Company’s 2014 Equity Incentive Plan and Stock Option Agreement, as applicable. 

  
 - 5 - 













 The Company and Executive acknowledge and agree that the terms and conditions set forth in
the Option Agreement are hereby amended as necessary to include the vesting acceleration provisions set forth in this Section 11. 

12. Company Matters. 

(a) Proprietary Information and Inventions. Executive acknowledges and agrees that she has signed, is bound by, and will continue to
abide by the terms of the At-Will Employment, Confidential Information, Invention Assignment, and Arbitration Agreement, which she executed on 12/13/2016 (the “Confidential Information
Agreement”), including the provisions governing the non-disclosure of confidential information and restrictive covenants contained therein. 

(b) Ventures. If, during her employment, Executive is engaged in or associated with planning or implementing of any project, program or
venture involving the Company and any third parties, all rights in such project, program or venture shall belong to the Company (or third party, to the extent provided in any agreement between the Company and the third party). Except as approved by
the Board in writing, Executive shall not be entitled to any interest in such project, program or venture or to any commission, finder’s fee or other compensation in connection therewith other than the salary or other compensation to be paid to
Executive as provided in this Agreement. 
 (c) Resignation on Termination. On termination of her employment, regardless of the
reason for such termination, Executive shall immediately (and with contemporaneous effect) resign any directorships, offices or other positions that he may hold in the Company or any affiliate, unless otherwise agreed in writing by the Parties. 

13. Arbitration. IN CONSIDERATION OF EXECUTIVE’S EMPLOYMENT WITH THE COMPANY, ITS PROMISE TO ARBITRATE ALL EMPLOYMENT-RELATED
DISPUTES AND EXECUTIVE’S RECEIPT OF THE COMPENSATION, PAY RAISES AND OTHER BENEFITS PAID TO EXECUTIVE BY THE COMPANY, AT PRESENT AND IN THE FUTURE, EXECUTIVE AGREES THAT ANY AND ALL CONTROVERSIES, CLAIMS, OR DISPUTES WITH ANYONE (INCLUDING THE
COMPANY AND ANY EMPLOYEE, OFFICER, DIRECTOR, SHAREHOLDER OR BENEFIT PLAN OF THE COMPANY, IN THEIR CAPACITY AS SUCH OR OTHERWISE), WHETHER BROUGHT ON AN INDIVIDUAL, GROUP, COLLECTIVE, OR CLASS BASIS, ARISING OUT OF, RELATING TO, OR RESULTING FROM
EXECUTIVE’S EMPLOYMENT WITH THE COMPANY OR THE TERMINATION OF EXECUTIVE’S EMPLOYMENT WITH THE COMPANY, INCLUDING ANY BREACH OF THIS AGREEMENT, SHALL BE SUBJECT TO BINDING ARBITRATION, AS SET FORTH IN THE CONFIDENTIAL INFORMATION AGREEMENT.

 14. Assignment. This Agreement will be binding upon and inure to the benefit of (a) the heirs, executors and legal
representatives of Executive upon Executive’s death and (b) any successor of the Company. Any such successor of the Company will be deemed substituted for the Company under the terms of this Agreement for all purposes. For this purpose,
“successor” means any person, firm, corporation or other business entity which at any time, whether by purchase, merger or otherwise, directly or indirectly acquires all or substantially all of the assets or business of the Company. None
of the rights of Executive to receive any form of compensation payable pursuant to this Agreement may be assigned or transferred except by will or the laws of descent and distribution. Any other attempted assignment, transfer, conveyance or other
disposition of Executive’s right to compensation or other benefits will be null and void. 
 15. Notices. All notices, requests,
demands and other communications called for under this Agreement shall be in writing and shall be delivered personally by hand or by courier, mailed by United States first-class mail, postage prepaid, or FedEx overnight directed to the Party to be
notified at the address indicated

for such Party on the signature page to this Agreement, or at such other address as such Party may designate by ten (10) days’ advance written notice to the other Parties hereto. In
addition, the Company may deliver to Executive any notices, requests, demands and other communications called for under this Agreement by e-mail. All such notices and other communications shall be deemed given
upon personal delivery or being e-mailed, or three (3) days after the date of mailing. 
 16.
Severability. In the event that any provision hereof becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, this Agreement will continue in full force and effect without said provision. 

17. Integration. This Agreement, together with the 2014 Stock Plan, Option Plan, Option Agreement and the Confidential Information
Agreement represents the entire agreement and understanding between the parties as to the subject matter herein and supersedes all prior or contemporaneous agreements whether written or oral. No waiver, alteration, or modification of any of the
provisions of this Agreement will be binding unless in writing and signed by duly authorized representatives of the parties hereto. 
 18.
Tax Withholding. All payments made pursuant to this Agreement will be subject to withholding of applicable taxes. 
 19.
Waiver. No Party shall be deemed to have waived any right, power or privilege under this Agreement or any provisions hereof unless such waiver shall have been duly executed in writing and acknowledged by the Party to be charged with such
waiver. The failure of any Party at any time to insist on performance of any of the provisions of this Agreement shall in no way be construed to be a waiver of such provisions, nor in any way to affect the validity of this Agreement or any part
hereof. No waiver of any breach of this Agreement shall be held to be a waiver of any other subsequent breach 
 20. Governing Law.
This Agreement will be governed by the laws of the State of California (with the exception of its conflict of laws provisions). 
 21.
Conflict Waiver. Each of the Parties to this Agreement understands that Wilson Sonsini Goodrich & Rosati, Professional Corporation (“WSGR”), is serving as counsel to the Company in connection with the transactions
contemplated hereby, and that discussion of such transactions with Executive could be construed to create a conflict of interest. By executing this Agreement, the Parties hereto acknowledge the potential conflict of interest and waive the right to
claim any conflict of interest at a later date. Furthermore, by executing this Agreement, the Parties acknowledge that if a conflict of interest exists and any litigation arises between Executive and the Company, WSGR would represent the Company.
Executive represents and warrants that she has had the opportunity to seek independent counsel in her review of this and all related agreements and that she is not relying on WSGR for any legal, tax or other advice relating to such agreements. 

22. Acknowledgment. Executive acknowledges that she has had the opportunity to discuss this matter with and obtain advice from her
legal counsel, has had sufficient time to, and has carefully read and fully understands all the provisions of this Agreement, and is knowingly and voluntarily entering into this Agreement. 

23. Counterparts. This Agreement may be executed in multiple counterparts, each of which shall be deemed to be an original, and all
such counterparts shall constitute but one instrument. 
 24. Effect of Headings. The section and subsection headings contained
herein are for convenience only and shall not affect the construction hereof. 
 25. Construction of Agreement. This Agreement has
been negotiated by the respective Parties, and the language shall not be construed for or against either Party.

 26. Section 409A. 

(a) Notwithstanding anything to the contrary in this Agreement, no severance pay or benefits to be paid or provided to Executive, if any,
pursuant to this Agreement, when considered together with any other severance payments or separation benefits that are considered deferred compensation under Section 409A (together, the “Deferred Compensation Separation
Benefits”) will be paid or otherwise provided until Executive has a “separation from service” within the meaning of Section 409A. 

(b) Notwithstanding anything to the contrary in this Agreement, if Executive is a “specified employee” within the meaning of
Section 409A at the time of Executive’s termination (other than due to death), then the Deferred Compensation Separation Benefits that are payable within the first six (6) months following Executive’s separation from service,
will become payable on the first payroll date that occurs on or after the date six (6) months and one (1) day following the date of Executive’s separation from service. All subsequent Deferred Compensation Separation Benefits, if any,
will be payable in accordance with the payment schedule applicable to each payment or benefit. Notwithstanding anything herein to the contrary, if Executive dies following Executive’s separation from service, but prior to the six (6) month
anniversary of the separation from service, then any payments delayed in accordance with this paragraph will be payable in a lump sum as soon as administratively practicable after the date of Executive’s death and all other Deferred
Compensation Separation Benefits will be payable in accordance with the payment schedule applicable to each payment or benefit. Each payment and benefit payable under this Agreement is intended to constitute separate payments for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations. 
 (c) Any amount paid under this Agreement that
satisfies the requirements of the “short-term deferral” rule set forth in Section 1.409A-1(b)(4) of the Treasury Regulations will not constitute Deferred Compensation Separation Benefits for
purposes of clause (a) above. 
 (d) Any amount paid under this Agreement that qualifies as a payment made as a result of an
involuntary separation from service pursuant to Section 1.409A-1(b)(9)(iii) of the Treasury Regulations that does not exceed the Section 409A Limit will not constitute Deferred Compensation
Separation Benefits for purposes of clause (a) above. For purposes of this Agreement, “Section 409A Limit” will mean the lesser of two (2) times: (i) Executive’s annualized compensation based upon
the annual rate of pay paid to Executive during the Executive’s taxable year preceding Executive’s taxable year of Executive’s termination of employment as determined under Treasury Regulation
Section 1.409A-1(b)(9)(iii)(A)(1) and any Internal Revenue Service guidance issued with respect thereto; or (ii) the maximum amount that may be taken into account under a qualified plan pursuant to
Section 401(a)(17) of the Code for the year in which Executive’s employment is terminated. 
 (e) The foregoing provisions are
intended to comply with the requirements of Section 409A so that none of the severance payments and benefits to be provided hereunder will be subject to the additional tax imposed under Section 409A, and any ambiguities herein will be
interpreted to so comply. The Company and Executive agree to work together in good faith to consider amendments to this Agreement and to take such reasonable actions which are necessary, appropriate or desirable to avoid imposition of any additional
tax or income recognition prior to actual payment to Executive under Section 409A.
