Re: Employment Agreement

On behalf of Translate Bio, Inc. (“Translate Bio” or the “Company”), I am pleased to offer you the position of the Company’s Chief Financial Officer (“CFO”). The key provisions of this offer (the “Agreement”) is contingent upon full Board approval. Please note this offer is also contingent upon the successful completion of references and routine background checks and work authorization.

1. Position. As the Company’s CFO you will report to the Company’s Chief Executive Officer (“CEO”), working out of the company’s Lexington, Massachusetts office and traveling as required by your job duties. This is a full-time employment position and you will have the usual and customary duties and responsibilities associated with the position of Chief Financial Officer. You shall devote your entire business time, loyalty, attention and efforts to the business and affairs of the Company and its affiliates. You agree to abide by the rules, regulations, instructions, personnel practices and policies of the Company and any changes therein that may be adopted from time to time by the Company. It is understood and agreed that, while you are employed by the Company, you will not engage in any other employment, consulting or other business activities (whether full-time or part-time), without the prior written consent of the CEO, provided, however, that you may engage in religious, charitable and other community activities so long as such activities do not interfere or conflict with your obligations to the Company.

2. Start Date. Your employment with the Company will begin on or before May 21, 2018. For purposes of this Agreement, the actual first day of your employment with the Company shall be referred to as the “Start Date.”

3. Salary. During the first year of your employment, the Company will pay you a base salary annualized at the rate of $375,000 per year, payable in accordance with the Company’s standard payroll schedule and subject to applicable deductions and withholdings (the “Base Salary”). Thereafter, the Base Salary will be subject to periodic review and adjustments at the Board’s discretion. You will be reimbursed by the Company

for reasonable business and travel expenses incurred in connection with the performance of your duties as CFO subject to compliance with applicable Company policies pertaining thereto, such as providing documentation for such expenses.

4. Bonus Compensation. Following the end of each fiscal year and subject to the approval of the Company’s Board (or a committee thereof), you will be eligible for a retention and performance bonus, targeted at thirty (30%) percent of your then Base Salary (the “Target Bonus”); upon an IPO of the Company your Target Bonus will increase to thirty five (35%) percent, in accordance with the Company’s bonus policy. Any bonus for calendar year 2018 will not be prorated based on your start date. The actual bonus is discretionary and will be subject to assessment of your performance, as well as business conditions at the Company as determined by the Board or its compensation committee. Except as provided in section 8 below, you must be an active employee of the Company on the date any bonus is distributed in order to be eligible for and to earn a bonus award, as it also serves as an incentive to remain employed by the Company, provided that the Company will award and pay any bonus for the prior calendar year before March 15th of the next succeeding calendar year.

Sign-on Bonus/Relocation. To help you relocate from California to Massachusetts, you will be eligible for a sign-on/relocation bonus not to exceed $50,000, including a taxable gross-up on eligible expenses, and up to three (3) months of temporary housing. Typical costs associated with relocation include storage, temporary living, transportation to your final move destination and your household goods move. Corporate relocation can have personal tax implications. Please contact your tax advisor for more information related to the tax implications of your relocation. If you leave the Company within one (1) year of receiving payment of these expenses, you are required to repay the Company for the total of such amounts within one week of your termination date, and any money owed may be deducted from your last paycheck and/or expense report.

The Company shall reimburse up to $5,000 in travel related expenses for you or your immediate family members for travel until September 1, 2018.

5. Equity

(a) Subject to final approval by the Board, receipt of all other required approvals to be secured contemporaneously and your acceptance of this Agreement, you shall be granted 2,316,554 Incentive Stock Options, which equals 1% of the Company’s currently outstanding equity on a fully-diluted basis as of the date hereof, (the “Equity Award”).

Xxxx X. Xxxxxxx, CFA

May 14, 2018

Page -3-

and the Company’s standard form agreement for the award of Incentive Stock Options (the “Grant Agreement”). The Incentive Stock Options will be issued with a Strike Price determined in accordance with the terms of the equity incentive plan. The Equity Award shall be subject to a four- year vesting schedule in which 25% of the Incentive Stock Options subject to the Equity Award shall vest on the one-year anniversary of the Start Date and the remainder shall vest on a monthly basis over the following 36 months, subject to continued employment. Notwithstanding the above, in the event that the Company terminates your employment without Cause or you resign with Good Reason (both as defined in the Grant Agreement), within 12 months following a Sale of the Company (as defined in the Grant Agreement), you shall immediately vest in all Incentive Stock Options subject to the Equity Award.

(b) The Board may also, in its discretion, award you additional Incentive Stock Options subject to time based and/or performance based vesting. The terms of the equity incentive plan and any associated award agreement (collectively the “Equity Documents”) shall apply to any equity grant. In the event of any conflict between the terms set forth in this Agreement and the terms of the Equity Documents, the terms of the Equity Documents shall control.

6. Benefits/Vacation. You will be eligible to participate in the employee benefits and insurance programs that the Company establishes and makes available to its employees from time to time, provided that you are eligible under (and subject to all provisions of) the plan documents governing those programs. Benefits are subject to change at any time in the Company’s sole discretion. You will be entitled to four (4) weeks of paid vacation per year, accrued on a pro-rata basis, to be taken at such times as may be approved by the Company. Pursuant to Company policy, a maximum of vacation days may be carried over from year to year.

7. At-Will Employment; Accrued Obligations. Your employment is “at will,” meaning you or the Company may terminate it at any time for any or no reason. Except as provided in section 8 below, in the event of the ending of your employment for any reason, the Company shall pay you: (i) your base salary plus any accrued but unused vacation through your last day of employment (the “Date of Termination”), and (ii) the amount of any documented expenses properly incurred by you on behalf of the Company prior to any such termination and not yet reimbursed (the “Accrued Obligations”).

if elected, continuation of group health plan benefits to the extent authorized by and consistent with 29 U.S.C. § 1161 et seq. (commonly known as “COBRA”), with the cost of the regular premium for such benefits shared in the same relative proportion by the Company and you as in effect on the Date of Termination until the earlier of: (i) nine (9) months from the Date of Termination or (ii) the date you and your dependents become eligible for health benefits through another employer or otherwise become ineligible for COBRA; and continuation of your Base Salary for nine (9) months following the Date of Termination.

If the Company cures the Good Reason condition during the Cure Period, Good Reason shall be deemed not to have occurred.

9. Confidential Information and Restricted Activities.

You agree without reservation that these restraints are necessary for the reasonable and proper protection of the Company and its affiliates, and that each and every one of the restraints is reasonable in respect to subject matter, length of time and geographic area. You further agree that, if were you to breach any of the covenants contained in this Agreement or the Restrictive Covenant Agreement, in addition to the Company’s other legal and equitable remedies, the Company may suspend or cease any Termination Benefits to which you might otherwise be entitled. Any such suspension or termination of the Termination Benefits by the Company in the event of a breach by you shall not affect your ongoing obligations to the Company.

10. Taxes; Section 409A

(a) All forms of compensation referred to in this Agreement are subject to reduction to reflect applicable withholding and payroll taxes and other deductions required by law. You hereby acknowledge that the Company does not have a duty to design its compensation policies in a manner that minimizes your tax liabilities, and you will not make any claim against the Company or its board of directors related to tax liabilities arising from your compensation.

(b) Anything in this Agreement 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 becomes entitled to under this Agreement on account of your separation from service would be considered deferred compensation subject to the 20% additional tax imposed pursuant to Section 409A(a) of the Code as a result of the application of Section 409A(a)(2)(B)(i) of the Code, 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. All in-kind benefits provided and expenses eligible for reimbursement under this Agreement shall be provided by the Company or incurred by you during the time periods set forth in this Agreement. It is intended that each installment of the severance payments set forth in the Agreement shall be treated as a separate “payment” for purposes of Section 409A. 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 Agreement constitutes “non-qualified deferred compensation” under Section 409A of the Code, 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.” 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-l(h). The Company and you intend that this Agreement will be administered in accordance with Section 409A of the Code. To the extent that any provision of this Agreement is ambiguous as to its compliance with Section 409A of the Code, the provision shall be read in such a manner so that all payments hereunder comply with Section 409A of the Code. The Company makes no representation or warranty and shall have no liability to you or any other person if any provisions of this Agreement are determined to constitute deferred compensation subject to Section 409A of the Code but do not satisfy an exemption from, or the conditions of, such Section.

(c) Interpretation, Amendment and Enforcement. This Agreement, including the Restrictive Covenant Agreement and the Equity Documents, constitutes the complete agreement between you and the Company, contains all of the terms of your employment with the Company and supersedes any prior agreements, representations or understandings (whether written, oral or implied) between you and the Company.
