This Separation Agreement and Release (“Agreement”) is made by and between Xxxxx X. Xxxxxxxxx, M.D. (“Executive”) and Seres Therapeutics, Inc. (the “Company”) (collectively referred to as the “Parties” or individually referred to as a “Party”). Capitalized terms used but not defined in this Agreement shall have the meanings set forth in the Employment Agreement (as defined below).

WHEREAS, the Parties have previously entered into that certain Employment Agreement, dated as of June 12, 2015, as amended by that certain First Amendment to Employment Agreement, dated February 3, 2016, and that certain Second Amendment to Employment Agreement, dated March 7, 2018, by and between the Parties (the “Employment Agreement”);

WHEREAS, Executive’s employment with the Company and its subsidiaries terminated effective January 14, 2019 (the “Separation Date”);

WHEREAS, in connection with Executive’s termination of employment, the Parties wish to resolve any and all disputes, claims, complaints, grievances, charges, actions, petitions, and demands that Executive may have against the Company and any of the Releasees as defined below, including, but not limited to, any and all claims arising out of or in any way related to Executive’s employment with or separation from the Company or its subsidiaries or affiliates but, for the avoidance of doubt, nothing herein will be deemed to release any rights or remedies in connection with Executive’s ownership of vested equity securities of the Company or Executive’s right to indemnification by the Company or any of its affiliates pursuant to contract or applicable law (collectively, the “Retained Claims”).

NOW, THEREFORE, in consideration of the severance payments and benefits described in Section 4 of the Employment Agreement, which, pursuant to the Employment Agreement, are conditioned on Executive’s execution and non-revocation of this Agreement, and in consideration of the mutual promises made herein, the Company and Executive hereby agree as follows:

1. Resignation of Employment; Continued Service on Board. Executive’s employment with the Company terminated effective as of the Separation Date. Effective as of the Separation Date, Executive ceased to serve as President and Chief Executive Officer of the Company and in any officer or other position with the Company or any of its subsidiaries or affiliates, except that following the Separation Date, Executive will continue to serve as Chairman of the Company’s board of directors (the “Board”) until Executive’s removal or resignation from such position or from the Board or Executive fails to be reelected by the Company’s stockholders. The Company expects that Executive’s continued service as Chairman of the Board will be considered by the Board on an annual basis for so long as Executive continues to serve on the Board. Executive will be eligible to receive compensation for such Board service in accordance with and subject to the terms of the Company’s Non-Employee Director Compensation Program as in effect from time to time. Under the terms of such program as in effect on the date hereof, in respect of service as Chairman of the Board, Executive is eligible to receive $55,000 per year (which includes the $35,000 annual retainer for Board service and the $20,000 additional annual retainer for service as Chairman of the Board), payable quarterly in arrears commencing on the Separation Date, and is eligible to receive an option to purchase 15,000 shares of the Common Stock of the Company on the date of the next annual meeting of stockholders.

2. Severance Payments; Salary and Benefits. The Company agrees to provide Executive with the severance payments and benefits described in Section 4(b) and/or Section 4(c) of the Employment Agreement (including, without limitation, an amount of cash equal to any Annual Bonus earned by Executive for the Company’s 2018 fiscal year in accordance with the terms of Section 4(b)(ii) of the Employment Agreement), payable at the times set forth in, and subject to the terms and conditions of, the Employment Agreement. In addition, to the extent not already paid, and subject to the terms and conditions of the Employment Agreement, the Company shall pay or provide to Executive all other payments or benefits described in Section 3(c) of the Employment Agreement, subject to and in accordance with the terms thereof.

3. Equity Awards. Exhibit A to this Agreement sets forth each Company stock option (the “Equity Awards”) held by Executive as of the Separation Date. The Parties agree that (i) each Equity Award was vested as of the Separation Date with respect to the number of shares subject to the Equity Award indicated on Exhibit A (the “Vested Options”) and (ii) the portion of each Equity Award that was unvested as of the Separation Date after giving effect to clause (i) of this sentence was forfeited and ceased to be outstanding on the Separation Date. For the avoidance of doubt, the Vested Options will remain exercisable for so long as Executive serves on the Board and for such period thereafter as provided in the applicable award agreement governing such Vested Option, and in no event later than their regular expiration date, subject to earlier termination in connection with a corporate transaction or other extraordinary event or occurrence in accordance with the terms of the Company’s 2015 Incentive Award Plan and the applicable award agreement.

4. Release of Claims. Executive agrees that, other than with respect to the Retained Claims, the foregoing consideration represents settlement in full of all outstanding obligations owed to Executive by the Company, any of its direct or indirect subsidiaries and affiliates, and any of its or their respective current and former officers, directors, equity holders, managers, employees, agents, investors, attorneys, shareholders, administrators, affiliates, benefit plans, plan administrators, insurers, trustees, divisions, and subsidiaries and predecessor and successor corporations and assigns (collectively, the “Releasees”). Executive, on Executive’s own behalf and on behalf of any of Executive’s affiliated companies or entities and any of Executive’s or their respective heirs, family members, executors, agents, and assigns, other than with respect to the Retained Claims, hereby and forever releases the Releasees from, and agrees not to xxx concerning, or in any manner to institute, prosecute, or pursue, any claim, complaint, charge, duty, obligation, or cause of action relating to any matters of any kind, whether presently known or unknown, suspected or unsuspected, that Executive may possess against any of the Releasees arising from any omissions, acts, facts, or damages that have occurred up until and including the date Executive signs this Agreement, including, without limitation:
