Rahul Ballal

Dear Rahul:

On behalf of IMARA Inc., a Delaware corporation (the “Company”), I am very pleased to offer you this revised “letter agreement” with the Company. This letter agreement shall supersede, amend and restate in all respects the letter agreement between you and the Company dated April 17, 2018, as amended and restated by the letter agreement between you and the Company dated August 12, 2019 (as amended and restated, the “Former Letter Agreement”), provided, and for the avoidance of doubt, that nothing herein supersedes the Invention and Non-Disclosure Agreement or the Non-Competition and Non-Solicitation Agreement signed by you concurrently with the Former Letter Agreement (the “Restrictive Covenant Agreements”), which remain in effect, unaltered, in all respects.

The terms of your employment with the Company are as set forth below:

1. Position. You will be employed to serve as Chief Executive Officer of the Company. As Chief Executive Officer, you will have the duties, authorities and responsibilities that are customarily associated with such position, and such other duties, authorities and responsibilities the Board of Directors of the Company (the “Board”) designates from time to time that are not inconsistent with such position. You will perform such duties to the Company primarily at the Company’s headquarters in Cambridge, Massachusetts. You will report directly to the Board. While an employee of the Company, you will devote substantially all of your professional time and efforts to the business of the Company. Any outside professional or other business activity you engage in must be approved in advance by the Board and must not conflict with your duties to the Company.

2. Compensation.

a. Base Salary. Commencing on April 1, 2019, your base salary is paid at the rate of $17,708 semi-monthly (i.e. a gross aggregate amount of $425,000 per annum assuming continuing service over a 12-month period), subject to tax and other withholdings as required by law. Your salary shall be reviewed annually by the Board.

b. Discretionary Bonus Program. You will be eligible for an annual discretionary bonus of up to forty percent (40%) of your annualized base salary to allow you to participate in the success of the Company based upon a combination of Company achievements and your performance, both as determined in the sole discretion of the Board. Any annual bonus

shall be paid no later than March 15^th of the year immediately following the year to which the applicable annual bonus relates, and you must be an active employee of the Company on the date any bonus is paid to be eligible for and to earn a bonus award. No bonus shall be considered to be earned until it is paid, as it also serves as an incentive to remain employed by the Company.

c. Option. The Company has granted you (i) an option to purchase 2,023,804 shares of the Company’s Class A Common Stock at a price per share equal to the fair market value per share of the common stock on the date of grant, as determined by the Board (the “Initial Option Grant”), and (ii) an option to purchase an additional 630,814 shares of the Company’s Class A Common Stock at a price per share equal to the fair market value per share of the common stock on the date of grant, as determined by the Board (the “Milestone Option Grant” and, together with the Initial Option Grant, the “Option”).

The Option shall be subject to all terms and other provisions set forth in the Company’s 2016 Stock Incentive Plan (as amended from time to time, the “Plan”)) and in a separate option agreement (“Option Agreement”), which will provide for (i) vesting of shares subject to the Option as follows so long as you have been continuously providing services to the Company as an employee, consultant or advisor through each vesting date: (A) 25% of such shares will vest on the first anniversary of the applicable Vesting Commencement Date (as defined below) and (B) the remainder of such shares will vest in equal quarterly installments after the first anniversary of the applicable Vesting Commencement Date over the three year period thereafter; and (ii) the acceleration of vesting on all unvested shares subject to the Initial Option Grant and (if the Milestone Closing has occurred) the Milestone Option Grant if a Qualifying Termination (as defined in Section 5(b)) occurs within 12 months after a Change of Control (as defined below) (such 12-month period, the “Change of Control Period”), so long as you have been continuously providing services as an employee (even if on leave of absence), consultant or advisor to the Company from the commencement of your employment up to and including such Change of Control through the date of such qualifying termination without Cause or such qualifying resignation for Good Reason, and provided that you timely sign and do not revoke a Release (as defined below). To avoid doubt, if the Milestone Closing has not occurred, the vesting of the shares subject to the Milestone Option Grant shall not be subject to acceleration as described in the preceding sentence.

The “Vesting Commencement Date(s)” for the Option shall be as follows: (A) for the Initial Option Grant, the Vesting Commencement Date shall be March 15, 2019, and (B) for the Milestone Option Grant, the Vesting Commencement Date shall be the date of the Milestone Closing (as defined in the Series B Preferred Stock Purchase Agreement dated as of March 15, 2019 (the “Purchase Agreement”)). In the event that the Milestone Closing does not occur prior to September 15, 2020 (eighteen (18) months following the Initial Closing (as defined in the Purchase Agreement), then the Milestone Option Grant shall be forfeited in its entirety.

5. Termination of Employment.

a. If you resign your employment with the Company without Good Reason or the Company terminates your employment for Cause you will receive no additional compensation other than: (i) any unpaid base salary for services rendered through the last day of your employment (the “Termination Date”); (ii) reimbursement of any un-reimbursed business

expenses incurred as of the Termination Date in accordance with the Company’s reimbursement policy; (iii) payment for any accrued but unused vacation time (if applicable) earned through the Termination Date; and (iv) all other earned payments, vested benefits or vested or earned fringe benefits to which you shall be entitled under the terms of any applicable compensation arrangement or benefit, equity or fringe benefit plan or program or grant or this letter agreement (collectively, clauses (i) through (iv) shall be referred herein as the “Accrued Benefits”). The Accrued Benefits will be paid to you consistent with applicable law.

b. If the Company terminates your employment for any reason other than Cause (except for termination due to your death or Disability,) or you resign for Good Reason (in either case, a “Qualifying Termination”), you will receive the Accrued Benefits, and, based upon satisfaction of the criteria in Section 5(d) below, including without limitation your execution and delivery of the separation and release agreement described therein and the lapse of any applicable revocation period without the release being revoked, you shall be eligible to receive the following severance benefits: (i) severance pay in the form of continuation of your base salary in effect as of the Termination Date for a period of twelve (12) months, less standard deductions, payable in accordance with the Company’s then regular pay policies commencing on or before the sixtieth (60th) day following the Termination Date (“Severance Pay”), provided, that the first such payment shall include any amounts that would have been paid to you hereunder had the release become effective upon the Termination Date; and (ii) following the Termination Date, if you are eligible for and elect to continue your health insurance coverage pursuant to your rights under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended, or any state equivalent (“COBRA”), then the Company shall reimburse you for your premiums under COBRA on a monthly basis until the earlier of (x) twelve (12) months following the Termination Date, or (y) the date upon which you commence full-time employment (or employment that provides you with eligibility for healthcare benefits substantially comparable to those provided by the Company) with an entity other than the Company. Notwithstanding any of the foregoing, if the 60-day period following the Termination Date would end in a calendar year subsequent to the year in which the Termination Date occurs, the payments under this Section 5(b) will not be paid or commence before the first payroll of the subsequent calendar year.

an event or circumstance set forth in clauses (i) through (vi) has occurred and the Company provides you with written notice after Company has knowledge of the occurrence of existence of such event or circumstance, which notice reasonably identifies the event or circumstance that the Company believes constitutes Cause and (B) with respect to the events and circumstances set forth in clauses (iv) and (v) only, you fail to substantially cure the event or circumstance so identified within 30 days of the receipt of such notice, if the Board considers the situation to be reasonably correctable.

6. Section 409A.

a. The intent of the parties is that payments and benefits under this letter agreement comply with, or be exempt from, Code Section 409A and, accordingly, to the maximum extent permitted, this letter agreement shall be interpreted to be in compliance therewith or exempt therefrom. If you notify the Company (with specificity as to the reason therefor) that you believe that any provision of this letter agreement (or of any award of compensation, including equity compensation or benefits) would cause you to incur any additional tax or interest under Code Section 409A and the Company concurs with such belief or

6

		Imara, Inc.
		116 Huntington Ave, 6th Floor Boston, MA 02116   ***@*** +1 ###-###-####   www.imaratx.com

the Company independently makes such determination, the Company shall, after consulting with you, reform such provision to try to comply with Code Section 409A through good faith modifications to the minimum extent reasonably appropriate to conform with Code Section 409A. To the extent that any provision hereof is modified in order to comply with Code Section 409A, such modification shall be made in good faith and shall, to the maximum extent reasonably possible, maintain the original intent and economic benefit to you and the Company of the applicable provision without violating the provisions of Code Section 409A.

b. A termination of employment shall not be deemed to have occurred for purposes of any provision of this letter agreement providing for the payment of any amounts or benefits upon or following a termination of employment that are considered “nonqualified deferred compensation” under Code Section 409A unless such termination is also a “separation from service” within the meaning of Code Section 409A and, for purposes of any such provision of this letter agreement, references to a “termination,” “termination of employment” or like terms shall mean “separation from service.” Notwithstanding any provision to the contrary in this letter agreement, no payments or benefits that are considered “nonqualified deferred compensation” under Code Section 409A to which you otherwise become entitled under this letter agreement in connection with your termination of employment, shall be made or provided to you prior to the earlier of (i) the expiration of the six (6) month period measured from the date of your “separation from service” with the Company (as such term is defined in Code Section 409A) or (ii) the date of your death, if you are deemed at the time of such separation from service to be a “specified employee” under Code Section 409A. Upon the expiration of the applicable Code Section 409A(a)(2) deferral period, all payments and benefits deferred pursuant to this Section 6(b) (whether they would have otherwise been payable in a single sum or in installments in the absence of such deferral) shall be paid or reimbursed to you in a lump sum, and any remaining payments and benefits due under this letter agreement shall be paid or provided in accordance with the normal payment dates specified for them herein.

c. All expenses or other reimbursements under this letter agreement shall be made promptly following submission of required documentation, and in any case on or prior to the last day of the taxable year following the taxable year in which such expenses were incurred by you (provided that if any such reimbursements constitute taxable income to you, such reimbursements shall be paid no later than March 15th of the calendar year following the calendar year in which the expenses to be reimbursed were incurred), and (i) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit and (ii) no such reimbursement or expenses eligible for reimbursement in any taxable year shall in any way affect the expenses eligible for reimbursement in any other taxable year, provided, that the foregoing clause (ii) shall not be violated with regard to expenses reimbursed under any arrangement covered by Section 105(b) of the Internal Revenue Code solely because such expenses are subject to a limit related to the period the arrangement is in effect.

d. For purposes of Code Section 409A, your right to receive any installment payment pursuant to this letter agreement shall be treated as a right to receive a series of separate and distinct payments. Neither you nor the Company shall have the right to accelerate or defer the delivery of any payments or benefits under this letter agreement except to the extent specifically permitted or required by Section 409A. Whenever a payment under this letter agreement specifies a payment period with reference to a number of days (e.g., “payment shall be made within thirty (30) days following the date of termination”), the actual date of payment within the specified period shall be within the sole discretion of the Company. Notwithstanding any other provision of this letter agreement to the contrary, in no event shall any payment under this letter agreement that constitutes “nonqualified deferred compensation” for purposes of Code Section 409A be subject to offset, counterclaim or recoupment by any other amount payable to you unless otherwise permitted by Code Section 409A.

7. Resolution of Disputes. Any controversy or claim arising out of or relating to your employment, this letter agreement, its enforcement or interpretation, or because of an alleged breach, default, or misrepresentation in connection with any of its provisions, shall be submitted to arbitration in Boston, Massachusetts before a single arbitrator (applying Massachusetts law), in accordance with the National Rules for the Resolution of Employment Disputes then in effect of the American Arbitration Association (“AAA”) as modified by the terms and conditions of this Section 7; provided, however, that provisional injunctive relief (including without limitation under the Restrictive Covenants Agreements) may, but need not, be sought in a court of law before or while arbitration proceedings are pending, and any provisional injunctive relief granted by such court shall remain effective until the matter is finally determined by the arbitrator. The arbitrator shall be selected by mutual agreement of the parties or, if the parties cannot agree, by striking from a list of arbitrators supplied by AAA. The arbitrator shall issue a written opinion revealing, however briefly, the essential findings and conclusions upon which the award is based. Final resolution of any dispute through arbitration may include any remedy or relief, which the arbitrator deems just and equitable. Any award or relief granted by the arbitrator hereunder shall be final and binding on the parties hereto and may be enforced by any court of competent jurisdiction.

The parties acknowledge that they are hereby waiving any rights to trial by jury in any action, proceeding or counterclaim brought by either of the parties against the other in connection with any matter whatsoever arising out of or in any way connected with this letter agreement or your employment.

The Company shall pay the arbitrator’s fees and arbitration expenses and any other costs associated with the arbitration or arbitration hearing that are unique to arbitration. The Company and you each shall separately pay its or your own deposition, witness, expert and attorneys’ fees and other expenses as and to the same extent as if the matter were being held in court unless otherwise provided by law. The arbitrator shall have the sole and exclusive power and authority to decide any and all issues of or related to whether this letter agreement or any provision of this letter agreement is subject to arbitration.

8. No Inconsistent Obligations. By accepting this offer of employment, you represent and warrant to the Company that you are under no obligations or commitments, whether contractual or otherwise, that are inconsistent with your obligations set forth in this letter agreement or that would be violated by your employment by the Company. You agree that you will not take any action on behalf of the Company or cause the Company to take any action that will violate any agreement that you have with a prior employer.

9. Section 280G.

a. Notwithstanding any other provision of this letter agreement, except as set forth in Section 9(b), in the event that the Company undergoes a “Change in Ownership or Control” (as defined below), the Company shall not be obligated to provide to you a portion of any “Contingent Compensation Payments” (as defined below) that you would otherwise be entitled to receive to the extent necessary to eliminate any “excess parachute payments” (as defined in Code Section 280G(b)(1)) for you. For purposes of this Section 9, the Contingent Compensation Payments so eliminated shall be referred to as the “Eliminated Payments” and the aggregate amount (determined in accordance with Treasury Regulation Section 1.280G-1, Q/A-30 or any successor provision) of the Contingent Compensation Payments so eliminated shall be referred to as the “Eliminated Amount.”

b. Notwithstanding the provisions of 9(a), no such reduction in Contingent Compensation Payments shall be made if (i) the Eliminated Amount (computed without regard to this sentence) exceeds (ii) 100% of the aggregate present value (determined in accordance with Treasury Regulation Section 1.280G-1, Q/A-31 and Q/A-32 or any successor provisions) of the amount of any additional taxes that would be incurred by you if the Eliminated Payments (determined without regard to this sentence) were paid to you (including, state and federal income taxes on the Eliminated Payments, the excise tax imposed by Section 4999 of the Code payable with respect to all of the Contingent Compensation Payments in excess of your “base amount” (as defined in Section 280G(b)(3) of the Code), and any withholding taxes). The override of such reduction in Contingent Compensation Payments pursuant to this Section 9(b) shall be referred to as a “Section 9(b) Override.” For purposes of this paragraph, if any federal or state income taxes would be attributable to the receipt of any Eliminated Payment, the amount of such taxes shall be computed by multiplying the amount of the Eliminated Payment by the maximum combined federal and state income tax rate provided by law.

c. For purposes of this Section 9 the following terms shall have the following respective meanings:

(I) “Change in Ownership or Control” shall mean a change in the ownership or effective control of the Company or in the ownership of a substantial portion of the assets of the Company determined in accordance with Section 280G(b)(2) of the Code.

(II) “Contingent Compensation Payment” shall mean any payment (or benefit) in the nature of compensation that is made or made available (under this letter agreement or otherwise) to a “disqualified individual” (as defined in Section 280G(c) of the Code) and that is contingent (within the meaning of Section 280G(b)(2)(A)(i) of the Code) on a Change in Ownership or Control of the Company.

d. Any payments or other benefits otherwise due to you following a Change in Ownership or Control that could reasonably be characterized (as determined by the Company) as Contingent Compensation Payments (the “Potential Payments”) shall not be made until the dates provided for in this Section 9(d). Within 30 days after each date on which you first become entitled to receive (whether or not then due) a Contingent Compensation Payment relating to such Change in Ownership or Control, the Company shall determine and notify you (with reasonable detail regarding the basis for its determinations) (i) which Potential Payments constitute Contingent Compensation Payments, (ii) the Eliminated Amount and (iii) whether the Section 9(b) Override is applicable. Within 30 days after delivery of such notice to you, you shall deliver a response to the Company (the “Executive Response”) stating either (A) that you agree with the Company’s determination pursuant to the preceding sentence, or (B) that you disagree with such determination, in which case you shall set forth (i) which Potential Payments should be characterized as Contingent Compensation Payments, (ii) the Eliminated Amount, and (iii) whether the Section 9(b) Override is applicable. In the event that you fail to deliver an Executive Response on or before the required date, the Company’s initial determination shall be final. If and to the extent that any Contingent Compensation Payments are required to be treated as Eliminated Payments pursuant to this Section 9, then the payments shall be reduced or eliminated, as determined by the Company, in the following order: (i) any cash payments, (ii) any taxable benefits, (iii) any nontaxable benefits, and (iv) any vesting of equity awards in each case in reverse order beginning with payments or benefits that are to be paid the farthest in time from the date that triggers the applicability of the excise tax, to the extent necessary to maximize the Eliminated Payments. If you state in the Executive Response that you agree with the Company’s determination, the Company shall make the Potential Payments to you within three business days following delivery to the Company of the Executive Response (except for any Potential Payments which are not due to be made until after such date, which Potential Payments shall be made on the date on which they are due). If you state in the Executive Response that you disagree with the Company’s determination, then, for a period of 60 days following delivery of the Executive Response, you and the Company shall use good faith efforts to resolve such dispute. If such dispute is not resolved within such 60-day period, such dispute shall be settled exclusively by arbitration in the Commonwealth of Massachusetts, in accordance with the rules of the American Arbitration Association then in effect. Judgment may be entered on the arbitrator’s award in any court having jurisdiction. The Company shall, within three business days following delivery to the Company of the Executive Response, make to you those Potential

Payments as to which there is no dispute between the Company and you regarding whether they should be made (except for any such Potential Payments which are not due to be made until after such date, which Potential Payments shall be made on the date on which they are due). The balance of the Potential Payments shall be made within three business days following the resolution of such dispute. Subject to the limitations contained in Sections 9(a) and 9(b) hereof, the amount of any payments to be made to you following the resolution of such dispute shall be increased by the amount of the accrued interest thereon computed at the prime rate announced from time to time by The Wall Street Journal, compounded monthly from the date that such payments originally were due.

e. The provisions of this Section 9 are intended to apply to any and all payments or benefits available to you under this letter agreement or any other agreement or plan of the Company under which you may receive Contingent Compensation Payments.

10. Miscellaneous.

a. This letter agreement may be executed in counterparts, each of which shall be deemed to be an original but all of which together will constitute one and the same instrument.

b. The Company may only assign this letter agreement to a successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company, provided, that such successor expressly agrees to assume and perform this letter agreement in the same manner and to the same extent that the Company would have been required to perform it if no such assignment had taken place, and the term “Company” shall include any such successor that assumes and agrees to perform this letter agreement, by operation of law or otherwise.

c. No provision of this letter agreement may be modified, waived or discharged unless such waiver, modification or discharge is agreed to in writing and signed by you and such officer as may be designated by the Board (other than you). No waiver by either party hereto at any time of any breach by the other party hereto of, or compliance with, any condition or provision of this letter agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time.
