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
the Offer Letter; and 
 WHEREAS, Executive desires to accept such employment and enter into such an agreement. 

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.

(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.

charge, duty, obligation, demand, or cause of action relating to any matters of any kind, whether presently known or unknown, suspected or unsuspected, that Employee may possess against any of the Releasees arising from any omissions, acts, facts,

 h. any and all claims for attorneys’ fees and costs. 

 Employee agrees that the release set forth in this section shall be and remain in effect in
all respects as a complete general release as to the matters released. This release does not extend to any obligations incurred under this Agreement or rights to benefits under any retirement plan in which the Employee is a participant according to
the terms of the plan. This release does not release claims that cannot be released as a matter of law, including any Protected Activity (as defined below). Any and all disputed wage claims that are released herein shall be subject to binding
arbitration in accordance with the Arbitration Paragraph below, except as required by applicable law. This release does not extend to any right Employee may have to (i) unemployment compensation benefits; (ii) workers’ compensation
benefits; or (iii) any right the Employee may have to COBRA benefits and any vested retirement benefits and/or 401(k) plan benefits for which she is eligible in accordance with the terms of the respective employee benefit plans. 

6. Acknowledgment of Waiver of Claims under ADEA. Employee acknowledges that Employee is waiving and releasing any rights Employee may have under the
Age Discrimination in Employment Act of 1967 (“ADEA”), and that this waiver and release is knowing and voluntary. Employee agrees that this waiver and release does not apply to any rights or claims that may arise under the ADEA after the
Effective Date of this Agreement. Employee acknowledges that the consideration given for this waiver and release is in addition to anything of value to which Employee was already entitled. Employee further acknowledges that he/she has been advised
by this writing that: (a) Employee should consult with an attorney prior to executing this Agreement; (b) Employee has twenty-one (21) days within which to consider this Agreement;
(c) Employee has seven (7) days following Employee’s execution of this Agreement to revoke this Agreement; (d) this Agreement shall not be effective until after the revocation period has expired; and (e) nothing in this
Agreement prevents or precludes Employee from challenging or seeking a determination in good faith of the validity of this waiver under the ADEA, nor does it impose any condition precedent, penalties, or costs for doing so, unless specifically
authorized by federal law. In the event Employee signs this Agreement and returns it to the Company in less than the 21-day period identified above, Employee hereby acknowledges that Employee has freely and
voluntarily chosen to waive the time period allotted for considering this Agreement. Employee acknowledges and understands that revocation must be accomplished by a written notification to the person executing this Agreement on the Company’s
behalf that is received prior to the Effective Date. The Parties agree that changes, whether material or immaterial, do not restart the running of the 21-day period. 

7. California Civil Code Section 1542. Employee acknowledges that Employee has been advised to consult with legal counsel and is
familiar with the provisions of California Civil Code Section 1542, a statute that otherwise prohibits the release of unknown claims, which provides as follows: 

A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR OR RELEASING PARTY DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE
TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM OR HER MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR OR RELEASED PARTY. 

 Employee, being aware of said code section, agrees to expressly waive any rights Employee
may have thereunder, as well as under any other statute or common law principles of similar effect. 
 8. No Pending or Future Lawsuits. Employee
represents that Employee has no lawsuits, claims, or actions pending in Employee’s name, or on behalf of any other person or entity, against the Company or any of the other Releasees. Employee also represents that Employee does not intend to
bring any claims on Employee’s own behalf or on behalf of any other person or entity against the Company or any of the other Releasees. 
 9.
Application for Employment. Employee understands and agrees that, as a condition of this Agreement, Employee shall not be entitled to any employment with the Company, and Employee hereby waives any right, or alleged right, of employment or re-employment with the Company. 
 10. Confidentiality. Subject to the Protected Activity Paragraph below, Employee
agrees to maintain in complete confidence the existence of this Agreement, the contents and terms of this Agreement, and the consideration for this Agreement (hereinafter collectively referred to as “Separation Information”). Except as
required by law, Employee may disclose Separation Information only to Employee’s immediate family members, the Court in any proceedings to enforce the terms of this Agreement, Employee’s attorney(s), and Employee’s accountant(s) and
any professional tax advisor(s) to the extent that they need to know the Separation Information in order to provide advice on tax treatment or to prepare tax returns, and must prevent disclosure of any Separation Information to all other third
parties. Employee agrees that Employee will not publicize, directly or indirectly, any Separation Information. 
 11. Trade Secrets and Confidential
Information/Company Property. Employee reaffirms and agrees to observe and abide by the terms of the Confidentiality Agreement, specifically including the provisions therein regarding nondisclosure of the Company’s trade secrets and
confidential and proprietary information. Employee’s signature below constitutes Employee’s certification under penalty of perjury that Employee has returned all documents and other items provided to Employee by the Company (with the
exception of a copy of the Employee Handbook and personnel documents specifically relating to Employee), developed or obtained by Employee in connection with Employee’s employment with the Company, or otherwise belonging to the Company.
Notwithstanding anything herein to the contrary, under the federal Defend Trade Secrets Act of 2016, an individual may not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that
(A) is made (i) in confidence to a Federal, State, or local government official, either directly or indirectly, or to an attorney; and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or
(B) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. An individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the
trade secret to the attorney of the individual and use the trade secret information in the court proceeding if the individual files any document containing the trade secret under seal and does not disclose the trade secret except pursuant to court
order. Nothing herein is intended, or should be construed, to affect the immunities created by the Defend Trade Secrets Act of 2016. 

 12. No Cooperation. Subject to the Protected Activity paragraph below, Employee
agrees that Employee will not knowingly encourage, counsel, or assist any attorneys or their clients in the presentation or prosecution of any disputes, differences, grievances, claims, charges, or complaints by any third party against any of the
Releasees, unless under a subpoena or other court order to do so or as related directly to the ADEA waiver in this Agreement. Employee agrees both to immediately notify the Company upon receipt of any such subpoena or court order, and to furnish,
within three (3) business days of its receipt, a copy of such subpoena or other court order. If approached by anyone for counsel or assistance in the presentation or prosecution of any disputes, differences, grievances, claims, charges, or
complaints against any of the Releasees, Employee shall state no more than that Employee cannot provide counsel or assistance. 
 13.
Protected Activity Not Prohibited. Employee understands that nothing in this Agreement shall in any way limit or prohibit Employee from engaging in any Protected Activity. For purposes of this Agreement, “Protected Activity” shall
mean filing a charge, complaint, or report with, or otherwise communicating, cooperating, or participating in any investigation or proceeding that may be conducted by, any federal, state or local government agency or commission, including but not
limited to the Securities and Exchange Commission, the Equal Employment Opportunity Commission, the Occupational Safety and Health Administration, and the National Labor Relations Board (“Government Agencies”). Employee understands that in
connection with such Protected Activity, Employee is permitted to disclose documents or other information as permitted by law, and without giving notice to, or receiving authorization from, the Company. However, Employee waives the right to recover
any personal damages or other personal relief based on any claim, cause of action, demand, lawsuit or similar that is waived pursuant to this Agreement and brought by Employee or on Employee’s behalf by any third party, including as a member of
any class or collective action, except that Employee does not waive any right to receive and fully retain any monetary award from a government-administered whistleblower award program for providing information to a government agency. Notwithstanding
the foregoing, Employee agrees to take all reasonable precautions to prevent any unauthorized use or disclosure of any information that may constitute Company confidential information under the Confidentiality Agreement to any parties other than the
Government Agencies. Employee further understands that “Protected Activity” does not include the disclosure of any Company attorney-client privileged communications; Any language in the Confidentiality Agreement regarding Employee’s
right to engage in Protected Activity that conflicts with, or is contrary to, this paragraph is superseded by this Agreement. 
 14.
Nondisparagement. Employee agrees to refrain from any disparagement, defamation, libel, or slander of any of the Releasees, and agrees to refrain from any tortious interference with the contracts and relationships of any of the Releasees. The
Releasees agree to refrain from any disparagement, defamation, libel, or slander of Employee. Employee shall direct any inquiries by potential future employers to the Company’s human resources department, which shall use its best efforts to
provide only the Employee’s last position and dates of employment. 
 15. Breach. In addition to the rights provided in the
“Attorneys’ Fees” section below, Employee acknowledges and agrees that any material breach of this Agreement, unless such breach constitutes a legal action by Employee challenging or seeking a determination in good faith of the
validity of the waiver herein under the ADEA, or of any provision of the Confidentiality Agreement shall entitle the Company immediately to recover and/or cease providing the consideration provided to Employee under this Agreement and to obtain
damages, except as provided by law. 

 16. No Admission of Liability. Employee understands and acknowledges that this
Agreement constitutes a compromise and settlement of any and all actual or potential disputed claims by Employee. No action taken by the Company hereto, either previously or in connection with this Agreement, shall be deemed or construed to be
(a) an admission of the truth or falsity of any actual or potential claims or (b) an acknowledgment or admission by the Company of any fault or liability whatsoever to Employee or to any third party. 

17. Costs. The Parties shall each bear their own costs, attorneys’ fees, and other fees incurred in connection with the preparation
of this Agreement. 
 18. ARBITRATION. 

ARBITRATION. THE PARTIES AGREE THAT ANY AND ALL DISPUTES ARISING OUT OF THE TERMS OF THIS AGREEMENT, THEIR INTERPRETATION, EMPLOYEE’S
EMPLOYMENT WITH THE CORPS OR THE TERMS THEREOF, OR ANY OF THE MATTERS HEREIN RELEASED, SHALL BE SUBJECT TO ARBITRATION IN SAN MATEO COUNTY, BEFORE A NEUTRAL ARBITRATOR WITH JUDICIAL ARBITRATION & MEDIATION SERVICES (“JAMS”),
PURSUANT TO ITS EMPLOYMENT ARBITRATION RULES & PROCEDURES (“JAMS RULES”). THE ARBITRATOR MAY GRANT INJUNCTIONS AND ALL OTHER RELIEF AVAILABLE AT LAW AND EQUITY IN SUCH DISPUTES. THE ARBITRATOR SHALL ADMINISTER AND CONDUCT ANY
ARBITRATION IN ACCORDANCE WITH CALIFORNIA LAW, INCLUDING THE CALIFORNIA CODE OF CIVIL PROCEDURE, AND THE ARBITRATOR SHALL APPLY SUBSTANTIVE AND PROCEDURAL CALIFORNIA LAW TO ANY DISPUTE OR CLAIM. WITHOUT REFERENCE TO ANY CONFLICT-OF-LAW PROVISIONS OF ANY JURISDICTION. TO THE EXTENT THAT THE JAMS RULES CONFLICT WITH CALIFORNIA LAW, CALIFORNIA LAW SHALL TAKE PRECEDENCE. THE DECISION OF THE
ARBITRATOR SHALL BE FINAL, CONCLUSIVE, AND BINDING ON THE PARTIES TO THE ARBITRATION. THE ARBITRATOR SHALL IN ALL CASES ISSUE A WRITTEN AWARD AND THE PARTIES AGREE THAT THE PREVAILING PARTY IN ANY ARBITRATION SHALL BE ENTITLED TO INJUNCTIVE RELIEF
IN ANY COURT OF COMPETENT JURISDICTION TO ENFORCE THE ARBITRATION AWARD. THE EMPLOYEE SHALL PAY THE EQUIVALENT AMOUNT OF THE FILING FEES ASSOCIATED WITH A CIVIL COURT ACTION; THE EMPLOYER SHALL PAY ALL OTHER COSTS AND EXPENSES OF SUCH ARBITRATION.
EACH PARTY SHALL SEPARATELY PAY FOR ITS OWN RESPECTIVE COUNSEL FEES AND EXPENSES ASSOCIATED WITH ARBITRATION; PROVIDED, HOWEVER, THAT THE ARBITRATOR SHALL AWARD ATTORNEYS’ FEES AND COSTS TO THE PREVAILING PARTY, EXCEPT AS PROHIBITED BY LAW. THE
PARTIES HEREBY AGREE TO WAIVE THEIR RIGHT TO HAVE ANY DISPUTE BETWEEN THEM RESOLVED IN A COURT OF LAW BY A JUDGE OR JURY. NOTWITHSTANDING THE FOREGOING, THIS SECTION WILL NOT PREVENT EITHER PARTY FROM SEEKING INJUNCTIVE RELIEF (OR ANY OTHER
PROVISIONAL REMEDY) FROM ANY COURT HAVING JURISDICTION OVER THE PARTIES AND THE SUBJECT MATTER OF THEIR DISPUTE RELATING TO THIS AGREEMENT AND THE AGREEMENTS INCORPORATED HEREIN BY REFERENCE. SHOULD ANY PART OF THE ARBITRATION AGREEMENT CONTAINED IN
THIS PARAGRAPH CONFLICT WITH ANY OTHER ARBITRATION AGREEMENT BETWEEN THE PARTIES, THE PARTIES AGREE THAT THIS ARBITRATION AGREEMENT SHALL GOVERN. 

 19. Tax Consequences. The Company makes no representations or warranties with respect
to the tax consequences of the payments and any other consideration provided to Employee or made on Employee’s behalf under the terms of this Agreement. Employee agrees and understands that Employee is responsible for payment, if any, of local,
state, and/or federal taxes on the payments and any other consideration provided hereunder by the Company and any penalties or assessments thereon. Employee further agrees to indemnify and hold the Releasees harmless from any claims, demands,
deficiencies, penalties, interest, assessments, executions, judgments, or recoveries by any government agency against the Company for any amounts claimed due on account of (a) Employee’s failure to pay or delayed payment of federal or
state taxes, or (b) damages sustained by the Company by reason of any such claims, including attorneys’ fees and costs. 
 20.
Authority. The Company represents and warrants that the undersigned has the authority to act on behalf of the Company and to bind the Company and all who may claim through it to the terms and conditions of this Agreement. Employee represents
and warrants that Employee has the capacity to act on Employee’s own behalf and on behalf of all who might claim through Employee to bind them to the terms and conditions of this Agreement. Each Party warrants and represents that there are no
liens or claims of lien or assignments in law or equity or otherwise of or against any of the claims or causes of action released herein. 

21. Severability. In the event that any provision or any portion of any provision hereof or any surviving agreement made a part hereof
becomes or is declared by a court of competent jurisdiction or arbitrator to be illegal, unenforceable, or void, this Agreement shall continue in full force and effect without said provision or portion of provision. 

22. Attorneys’ Fees. Except with regard to a legal action challenging or seeking a determination in good faith of the validity of
the waiver herein under the ADEA, in the event that either Party brings an action to enforce or effect its rights under this Agreement, the prevailing Party shall be entitled to recover its costs and expenses, including the costs of mediation,
arbitration, litigation, court fees, and reasonable attorneys’ fees incurred in connection with such an action. 
 23. Entire
Agreement. This Agreement represents the entire agreement and understanding between the Company and Employee concerning the subject matter of this Agreement and Employee’s employment with and separation from the Company and the events
leading thereto and associated therewith, and supersedes and replaces any and all prior agreements and understandings concerning the subject matter of this Agreement and Employee’s relationship with the Company, with the exception of the
Confidentiality Agreement, except as otherwise modified or superseded herein. 

 24. No Oral Modification. This Agreement may only be amended in a writing signed by
Employee and the Company’s Chief Executive Officer. 
 25. Governing Law. This Agreement shall be governed by the laws of the
State of California, without regard for choice-of-law provisions. Employee consents to personal and exclusive jurisdiction and venue in the State of California. 

26. Effective Date. Employee understands that this Agreement shall be null and void if not executed by Employee within twenty-one (21) days of the Separation Date. Each Party has seven (7) days after that Party signs this Agreement to revoke it. This Agreement will become effective on the eighth (8th) day after Employee
signed this Agreement, so long as it has been signed by the Parties and has not been revoked by either Party before that date (the “Effective Date”). 

27. Counterparts. This Agreement may be executed in counterparts and each counterpart shall be deemed an original and all of which
counterparts taken together shall have the same force and effect as an original and shall constitute an effective, binding agreement on the part of each of the undersigned. The counterparts of this Agreement may be executed and delivered by email
