In your role, you will report directly to me. All your duties are to be performed and discharged faithfully, diligently and to the best of your ability and in compliance with internal procedures and all applicable laws and regulations.

Compensation:

As a full-time, exempt employee, you will receive a monthly salary of $31,250.00 ($375,000 on an annualized basis), to be paid in accordance with Verve’s standard payroll practice. In addition to your base salary, you will be eligible for an annual bonus target of thirty-five percent (35%) of your base salary.

Stock Options:

Upon or promptly after you sign and return this letter agreement, Verve will grant you an option to purchase 1,000,000 shares of the Company’s common stock at an exercise price of $0.15 per share which is equal to the fair market value per share of the common stock on the date of the grant. This option award will be subject to the provisions of the Company’s 2018 Equity Incentive Plan, as may be amended from time to time (the “Plan”) or any successor plan and stock option agreements on the Company’s standard form (as modified as appropriate to reflect the terms set forth herein) to be entered into by you and the Company following the grant (collectively, the “Equity Documents”), which in relevant part will provide that such option (i) vests over a period of four years, with an initial 25% one-year cliff and monthly vesting thereafter, subject to your continued service relationship as an employee or a consultant (“service relationship”) through each applicable vesting date; (ii) expires ten (10) years from the grant date, subject to earlier termination pursuant to the terms of the Plan relating to mergers, changes in control, dissolutions and liquidations and similar events; and (iii) may be exercised (as to the vested portion) for twenty four (24) months following the termination of your service relationship with the Company (including in the event the termination of your service relationship is due to your death or Disability (as defined in the Plan)).

Notwithstanding anything to the contrary in the Equity Documents or in any other agreement, in the event of a Change in Control (as defined in the Plan), 100% of the unvested shares underlying all equity awards made hereunder, previously made to you or issued to you as of the date of such Change in Control, shall immediately vest and, if applicable, become fully exercisable (or if restricted stock nonforfeitable).

Benefits:

You will be eligible to participate in Verve’s employee benefits in the same manner provided generally to Verve’s exempt employees, including its 401(k) savings plan, health and dental insurance, and life and disability insurance, subject to the satisfaction of any eligibility requirements and subject to the terms of such benefit programs.

Section 409A:

Anything in this offer letter to the contrary notwithstanding, if at the time of your separation from service within the meaning of Section 409A of the Code, the Company determines that you are a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) of the Code, then to the extent any payment or benefit that you become entitled to under this offer letter on account of your separation from service constitutes “non-qualified deferred compensation” under Section 409A of the Code or the regulations and guidance thereunder (collectively, “Section 409A”), such payment shall not be payable and such benefit shall not be provided until the date that is the earlier of (A) six months and one day after your separation from service, or (B) your death. If any such delayed cash payment is otherwise payable on an installment basis, the first payment shall include a catch-up payment covering amounts that would otherwise have been paid during the six-month period but for the application of this provision, and the balance of the installments shall be payable in accordance with their original schedule. Each payment, installment and benefit payable under this offer letter is intended to constitute a separate payment for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations. All in-kind benefits provided and expenses eligible for reimbursement under this offer letter shall be provided by the Company or incurred by you during the time periods set forth in this offer letter. All reimbursements shall be paid as soon as administratively practicable, but in no event shall any reimbursement be paid after the last day of the taxable year following the taxable year in which the expense was incurred. The amount of in-kind benefits provided or reimbursable expenses incurred in one taxable year shall not affect the in-kind benefits to be provided or the expenses eligible for reimbursement in any other taxable year. Such right to reimbursement or in-kind benefits is not subject to liquidation or exchange for another benefit. To the extent that any payment or benefit described in this offer letter constitutes “non-qualified deferred compensation” under Section 409A, and to the extent that such payment or benefit is payable upon your termination of employment, then such payments or benefits shall be payable only upon your “separation from service.” Similarly, no

severance payable to you, if any, pursuant to this offer letter that otherwise would be exempt from Section 409A pursuant to Treasury Regulation Section 1.409A-1(b)(9) will be payable until you have a “separation from service” within the meaning of Section 409A. The determination of whether and when a separation from service has occurred shall be made in accordance with the presumptions set forth in Treasury Regulation Section 1.409A 1(h). The Company and you intend that this offer letter will be exempt from or otherwise comply with Section 409A so that none of the severance or other payments and benefits to be provided hereunder will be subject to the additional tax imposed under Section 409A, and this offer letter will be administered in accordance with such intent. To the extent that any terms or provision of this offer letter is ambiguous as to its exemption from or compliance with Section 409A of the Code, the term or provision, as applicable, shall be read in such a manner so that all payments hereunder are exempt from or comply with Section 409A. In no event will the Company have any obligation to reimburse you for any taxes or costs that may be imposed on or incurred by you as a result of Section 409A. You and the Company agree to work together in good faith to consider amendments to this offer 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 you under Section 409A.

In accepting this offer, you give us your assurance that you have not relied on any agreements, promises or representations, express or implied, with respect to your employment that are not set forth expressly in this letter. This offer letter may not be modified or amended except in a writing signed by both you and the me, as Chief Executive Officer.
