Dear ▇▇▇▇,
The purpose of this letter agreement (“Agreement”) is to confirm the terms of this separation of employment from Synlogic, Inc. (“Synlogic” or “the Company”).1 The Severance Pay and Benefits described below are contingent on your agreement to and compliance with the provisions of this Agreement, as set forth below. This Agreement shall be effective on the day after you sign the same (the “Effective Date”), and the terms herein shall supersede the prior agreements entered into by you and the Company related to such subject matter, including (i) the Employment Letter Agreement dated November 28, 2018, as amended by the Promotion Letter dated July 1, 2020 and the Amendment to the Employment Letter Agreement dated December 26, 2023; (ii) the Retention Agreement dated March 1, 2024, as amended by the Amendment to the Retention Agreement dated May 31, 2024, the Amendment to the Retention Agreement dated August 8, 2024, and the Amendment to the Retention Agreement dated October 29, 2024; and (iii) the Separation Agreement dated February 26, 2024, as amended by the Amendment to the Separation Agreement dated May 29, 2024, the Amendment to the Separation Agreement dated August 5, 2024, and the Amendment to the Separation Agreement dated October 29, 2024 (the “Prior Agreements”).
1.Separation of Employment. As previously communicated to you, your employment with the Company ends on 12/31/2024 (the “Separation Date”). You acknowledge that from and after the Separation Date, you have no authority to, and shall not, represent yourself as an employee or agent of the Company.
2.Severance Pay and Benefits. If you sign this Agreement, do not revoke your acceptance of this Agreement and otherwise comply with the terms of this Agreement, the Company will provide you with the following:
(i)Severance Pay in the form of a lump-sum payment equivalent to six (6) months of your base salary, or $218,856 less all tax withholdings and any other authorized deductions paid within thirty (30) days of the Separation Date.
(ii)Health. You will have the right to continue your participation in Synlogic’s medical and dental insurance programs through the Separation Date. You will then have the right to
1 Except for the obligations set forth in Section 2 which shall be solely the obligations of Synlogic, Inc., whenever the term Synlogic, Inc. is otherwise used in this Agreement (including, without limitation, Section 7), it shall be deemed to include Synlogic, Inc., and any and all of its divisions, affiliates and subsidiaries and all related entities (including investors), and its and their directors, officers, employees, agents, successors and assigns.
continue your participation in Synlogic’s medical and dental insurance programs subject to your timely applying and being eligible for such benefits pursuant to the provisions of the Consolidated Omnibus Budget Reconciliation Act of 1985 (COBRA), subject to the requirements of COBRA and the continuation of the Company medical and dental plans by its insurance carrier. If you sign this Agreement and it becomes effective as set forth below, and elect COBRA coverage, the Company will continue to pay on your behalf the Company premium for such coverage for the lesser of the six (6) months after the Separation Date commencing January 2025, the date you become eligible for coverage under a subsequent employer’s group health benefits and the date you are no longer eligible for COBRA coverage. Your medical and dental plan contributions will be deducted from your severance pay. Thereafter, your continuation of your medical and dental insurance pursuant to the provisions of COBRA will be solely at your own cost. The “qualifying event” under COBRA shall be deemed to have commenced on the Separation Date. In the event that the Company, in connection with the winding down of its business, terminates its group health plan coverage within six (6) months of the Separation Date and you otherwise remain eligible for coverage under this Section, the Company shall provide you with a taxable lump sum payment equal to the Company’s contribution to the cost of the currently selected medical benefit option times the number of months remaining in the severance period following cessation of the Company’s group health plan coverage.
(iii)2024 Bonus: You will be paid a lump-sum payment in an amount equal to 100% of your target 2024 bonus, less all tax withholdings and any other authorized deduction, within thirty (30) days of the Separation Date.
(iv)Retention Bonus. You will be paid a lump-sum payment equivalent to seventy-five percent (75%) of your base salary for each month of service to the Company between March 1, 2024 and December 31, 2024, or $246,213 less all tax withholdings and any other authorized deduction, within thirty (30) days of the Separation Date.
(v)You acknowledge and agree that the Severance Pay and Benefits set forth in the sub-sections above are consistent with the provisions of the Prior Agreements, and that your signing of this Agreement is a condition precedent to the receipt of such Severance Pay and Benefits.
3.Equity. Your outstanding equity awards (“Equity Grants”) shall remain subject to the original terms and conditions of such Equity Grants, including that the unvested portion of any Equity Grants will be forfeited as of the Separation Date, provided, that if you timely enter into the Consulting Agreement (defined in Section 4), you will remain eligible to continue to vest in your Equity Grants while you continue to be engaged to provide services under the Consulting Agreement. The Separation Date or, if applicable, the date of termination of Executive’s services under the Consulting Agreement, is hereinafter referred to as the “Option Vesting End Date.” You will have 90 days following the Option Vesting End Date to exercise the vested portion of your Equity Grants in accordance with the terms of the applicable Equity Grant.
4.Consulting. The Company has requested that you enter into a consulting agreement, a copy of which has been provided to you along with this Agreement (the “Consulting Agreement”). Provided you enter into the Consulting Agreement simultaneously with this Agreement and provide the services set forth in the Consulting Agreement, you will continue to
vest in the Equity Grants in accordance with their terms through the date on which you or the Company terminates your consulting services in accordance with the terms of the Consulting Agreement (which date will become the Option Vesting End Date under Section 3).
5.Acknowledgements. You acknowledge and agree that the Severance Pay and Benefits to be provided to you are not intended to, and shall not constitute, a severance plan and shall confer no benefit on anyone other than the Company and you. You further acknowledge that except for any unpaid regular wages (including accrued and unused vacation) earned through the Separation Date, which shall be paid on or around the Separation Date, you have been paid and provided all wages, vacation pay, holiday pay, bonus, business expenses, and any other form of compensation or benefit that may be due to you now or which would have become due in the future in connection with your employment or separation of employment with the Company.
6.Return of Property, Confidentiality, Non-Disparagement. You expressly acknowledge and agree to the following:
(i)That you will abide by any and all obligations contained in the Non-Competition, Non-Solicitation, Invention and Non-Disclosure Agreement that you entered into in connection with Employment Letter Agreement dated November 28, 2018 between you and the Company and any terms of the Prior Agreements (copies of which can be provided to you), which survive the termination of the Prior Agreements. The forgoing obligations and terms are hereby incorporated by reference, which shall survive the signing of this Agreement, and you hereby affirm that you will comply with such obligations and terms. You further agree that you will keep all confidential information and trade secrets of the Company confidential, and that you will abide by any and all common law and/or statutory obligations relating to protection and non-disclosure of the Company’s trade secrets and/or confidential and proprietary documents and information. Consistent with applicable law, the Company is providing you with the notice of immunity set forth in Exhibit B, which is a part of this Agreement.
(ii)Without limiting the foregoing obligations, that by the Separation Date, you will promptly return to the Company all the Company documents (and any copies) and property (including all electronically stored information) regardless of where such documents, information or property is maintained. You acknowledge and agree that you shall not maintain any copies or duplicates of such documents or information. You further acknowledge that if you were to use or disclose any of the information reflected in such items, that this would cause immediate, substantial and irreparable harm to the Company.
(iii)That all information relating in any way to the negotiation and terms of this Agreement (except for your obligations under Section 5(i) above), including the amount of financial consideration provided for in this Agreement, shall be held confidential by you and shall not be publicized or disclosed to any person (other than an immediate family member, legal counsel, or financial advisor, provided that any such individual to whom disclosure is made agrees to be bound by these confidentiality obligations), business entity, or as otherwise mandated by state or federal law.
(iv)That you will not make any oral or written statements (including on any social media or other similar platform) that are professionally or personally disparaging about, or adverse
to, the interests of the Company (including its officers, directors, employees and consultants) including, but not limited to, any statements that disparage any person, product, service, finances, financial condition, capability or any other aspect of the business of the Company, and that you will not engage in any conduct which could reasonably be expected to harm professionally or personally the reputation of the Company (including its officers, directors, employees and consultants).
(v)That the Severance Pay and Benefits being offered are based on your representations that you have not engaged in any fraudulent or unlawful conduct, and that you have fully disclosed to the Company all material information relating to your job duties for the Company.
(vi)That in the event of your breach of any of your agreements set forth in this Section 5 the Company would suffer substantial irreparable harm and that the Company would not have an adequate remedy at law for such breach. In recognition of the foregoing, you agree that in the event of a breach or threatened breach of any of these covenants, in addition to such other remedies as the Company may have at law, without posting any bond or security, the Company shall be entitled to seek and obtain equitable relief, in the form of specific performance, or temporary, preliminary or permanent injunctive relief, or any other equitable remedy which then may be available. The seeking of such injunction or order shall not affect the Company’s right to seek and obtain damages or other equitable relief on account of any such actual or threatened breach. You further agree that the Company shall be entitled to its costs and fees, including attorneys’ fees, incurred by it should it prevail in enforcing and provision of this Agreement.
7.Cooperation/Transition of Duties. You agree that during the Severance Period you will make yourself reasonably available to the Company, upon reasonable notice, either by email, telephone or, if the Company believes necessary, in person to assist the Company in any matter relating to the services performed by you during your employment with the Company including, but not limited, transitioning your duties to others at the Company. You further agree that during this period of time and thereafter you will cooperate fully with the Company in the defense or prosecution of any claims or actions now in existence or which may be brought or threatened in the future against or on behalf of the Company, including any claim or action against its directors, officers and employees. Your cooperation in connection with such claims or actions shall include, your being available, within reason given the constraints of future employment or job search activities, to meet with the Company to prepare for any proceeding, to provide truthful affidavits and/or testimony, to assist with any audit, inspection, proceeding or other inquiry, and to act as a witness in connection with any litigation or other legal proceeding affecting the Company. You further agree that should an individual representing a party adverse to the business or legal interests of the Company (including, without limitation, anyone threatening any form of legal action against the Company) contact you (directly or indirectly), you will promptly (within 48 hours) inform the Company of that fact. Nothing herein shall be construed to prohibit or prevent you from cooperating with any government investigation (including maintaining the confidentiality of such investigation if required by the government), nor shall any such cooperation be deemed to be a violation of your obligations of non-disparagement set forth in Section 5(iv) above.
8.Release of Claims. You hereby acknowledge and agree that by signing this Agreement, you are waiving your right to assert any Claim (as defined below) against Synlogic
arising from acts or omissions that occurred on or before the Separation Date or the Effective Date, whichever is later. Please note definition of Synlogic contained in footnote 1 of this Agreement.

(i)Claims under any Law concerning discrimination, harassment, retaliation, or other fair employment practices, including, but not limited to the Massachusetts Anti-Discrimination and Anti-Harassment Law (M.G.L. c. 151B), the Massachusetts Sexual Harassment Law (M.G.L. c. 214, § 1C), the Massachusetts Equal Pay Act (M.G.L. c. 149, § 105A), the Massachusetts Civil Rights Act (M.G.L. c. 12, §§ 11H, 11I), the Massachusetts Equal Rights Act (M.G.L. c. 93, §§ 102, 103), the Age Discrimination in Employment Act (29 U.S.C. § 621 et seq.), Title VII of the Civil Rights Act of 1964 (42 U.S.C. § 2000e et seq.), 42 U.S.C. § 1981, the Civil Rights Act of 1991, Section 1981 of the U.S.C.

You specifically acknowledge that you are waiving any Claims for unpaid wages under these and other Laws.
(iii)Claims under any local, state or federal common law theory including, without limitation, any Claim for breach of contract, ownership of inventions or any other intellectual property, implied contract, misrepresentation (intentional or negligent), fraud, promissory estoppel, unjust enrichment, quantum meruit, defamation (libel or slander), or any other Claim sounding in contract or tort.
(iv)Claims arising under the Company’s policies or benefit plans.

Notwithstanding the foregoing, this Section shall not release Synlogic from any obligation expressly set forth in this Agreement. You acknowledge and agree that, but for providing this waiver and release, you would not be receiving the Severance Pay and Benefits provided for in this Agreement.
9.OWBPA. Because you are at least forty (40) years of age, you have specific rights under the federal Age Discrimination in Employment Act (“ADEA”) and Older Workers Benefit Protection Act (“OWBPA”), which prohibit discrimination on the basis of age. The release in Section 7 is intended to release any Claim you may have against Synlogic alleging discrimination on the basis of age under the ADEA, OWBPA, and other Laws. Notwithstanding anything to the contrary in this Agreement, the release in Section 7 does not cover rights or Claims under the ADEA that arise after the date you sign this Agreement or the Effective Date, whichever is later.
Further, it is the Company’s desire and intent to make certain that you fully understand the provisions and effects of this Agreement. To that end, the Company hereby advises you in writing to consult with legal counsel prior to signing this Agreement for the purpose of reviewing the terms of this Agreement. Also, because you are at least age 40, and consistent with the provisions of the OWBPA, the Company is providing you with over twenty-one (21) days from the date you are provided this Agreement to consider and accept the terms of this Agreement by signing below and returning it to ▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, Head of Finance at ▇▇▇▇▇▇▇▇@▇▇▇▇▇▇▇▇▇▇.▇▇▇ or returning it to Synlogic, PO Box 30, Winchester, MA 01890 c/o ▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, Head of Finance, and notifying ▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇ by email that it has been sent by hard copy. You further agree that any changes to this Agreement will not restart the running of this twenty-one (21) day period. In addition, you may rescind your assent to this Agreement if, within seven (7) days after you sign this Agreement, you deliver a notice of rescission to Synlogic. To be effective, such rescission must be hand delivered or postmarked within the seven (7) day period and sent by certified mail, return receipt requested, to ▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇ at Synlogic at the above referenced address.
Also, consistent with the provisions of state and federal discrimination laws (the “Discrimination Laws”), nothing in the general waiver and release set forth in Section 7 above shall be deemed to prohibit you from challenging the validity of this release under the Discrimination Laws or from filing a charge or complaint of age or other related discrimination with the Equal Employment Opportunity Commission (“EEOC”) or similar state agency, or from participating in any investigation or proceeding conducted by the EEOC or such state agency.
However, the release in Section 7 does prohibit you from seeking or receiving monetary damages or other individual-specific relief in connection with any such charge or complaint of age or other work-related discrimination. Further, nothing in this Agreement shall be deemed to limit Synlogic’s right to seek immediate dismissal of such charge or complaint on the basis that your signing of this Agreement constitutes a full release of any individual rights under the Discrimination Laws, or Synlogic’s right to seek restitution or other legal remedies to the extent permitted by law of the economic benefits provided to you under this Agreement in the event that you successfully challenge the validity of this release and prevail in any claim under the Discrimination Laws.
10.Consequences of Breach. In addition to any other remedies set forth in this Agreement, a breach by you of any of your obligations set forth in this Agreement shall constitute a material breach of this Agreement and, in addition to any other legal or equitable remedy available to Synlogic, shall entitle Synlogic to cease any further payment of the Severance Pay and Benefits, and to recover any Severance Pay or Benefits or its support for other benefits already provided to you. Regardless of any such breach, your release set forth in Section 7 above shall remain in full force and effect.
11.Entire Agreement/Choice of Law/Enforceability/Jury Waiver/Successors and Assigns.
(i)Except as otherwise expressly provided in this Agreement, this Agreement supersedes any and all other prior oral and/or written agreements, including the Prior Agreements, and sets forth the entire agreement between you and Synlogic. No variations or modifications hereof shall be deemed valid unless reduced to writing and signed by the parties hereto.
(ii)This Agreement shall be governed by the law of the state where you reside on the date you sign this Agreement, without giving effect to conflict of law principles.
(iii)Both parties further agree that any action, demand, claim or counterclaim relating to this Agreement shall be resolved by a judge alone, and both parties hereby waive and forever renounce the right to a trial before a civil jury.
(iv)If your release of Claims pursuant to Section 7 is determined to be unenforceable in whole or part, the Company will have the option, in its sole discretion, to either (a) declare the entire Agreement null and void and require you to refund the Severance Pay and Benefits provided for in this Agreement; or (b) enforce the portions of the Agreement found not to be unenforceable. In the event that any other provision of this Agreement is determined to be unenforceable in whole or part, the remainder of the Agreement shall be enforced in full.
(v)This Agreement shall inure to the benefit of Synlogic and any of its successors and assigns.
It is Synlogic’s desire and intent to make certain that you fully understand the provisions and effects of this Agreement. By executing this Agreement, you are acknowledging (a) that you have been afforded sufficient time to understand the terms and effects of this Agreement and to consult with legal counsel, (b) that your agreements and obligations hereunder are made voluntarily, knowingly and without duress, and (c) that
neither Synlogic nor its agents or representatives have made any representations inconsistent with the provisions of this Agreement.
If you agree to the terms of this Agreement, please sign and return the enclosed copy of this Agreement.
Very truly yours,
