Employment Separation Letter Agreement with

This letter agreement (this “Letter Agreement”) confirms the termination of your employment with Zymergen Inc. (the “Company”) and your resignation from all positions and offices with the Company and any of its affiliates, in each case, to take effect on April 1, 2022 (the “Separation Date”).

In connection with your termination, the Company wishes to provide certain separation benefits to you, and you wish to receive such separation benefits, subject to the terms and conditions below.

This Letter Agreement shall become a binding agreement between you and the Company on the date you sign this Letter Agreement.

Therefore, for the receipt of good and adequate consideration, you and the Company agree as follows:

1.    Final Pay; Business Expenses; Equity Grants.

    (a)    Upon the Separation Date, you will be paid all final wages accruing through the Separation Date as set forth on Exhibit A, in accordance with applicable law. You acknowledge and agree that the payments set forth on Exhibit A accurately and completely reflect all wages earned by you through the Separation Date, and that you are not entitled to any additional wages or benefits, including any salary, bonuses, commissions, benefits, or other compensation, in connection with your employment with or termination of employment from the Company, except as set forth in this Letter Agreement.

    (b)    As soon as possible and no later than the Separation Date, you will submit for reimbursement in accordance with the Company’s expense reimbursement policies and practices all unreimbursed business expenses, if any, incurred by you, so that the Company may promptly pay you.

    (c)    You acknowledge and agree that as of the Separation Date, the unvested portion of any Company stock options, restricted stock units (“RSUs”) or other equity awards held by you (after giving effect to the Separation Benefits, as defined in Section 3 below) shall terminate immediately.

2.    Consideration. With the receipt of the payments and benefits set forth in Section 1 above, you will have received all payments and benefits earned or owed to you in connection with your employment with the Company, and you shall not be entitled to any additional compensation or benefits, except as provided below, subject to the terms and conditions set forth in this Letter Agreement. You acknowledge that the compensation and benefits provided below are good and valid consideration for the release of claims and other covenants set forth below.

3.    Equity Awards. Provided you timely execute and return the general release attached hereto as Exhibit B (the “Release”), and subject to your continued compliance with the provisions set forth in Section 4 and Section 7 of this Letter Agreement, (i) all Company stock options held by you that are vested as of the Separation Date shall remain exercisable until April 1, 2023 and (ii) 17,708 of RSUs held by you that are unvested as of the Separation Date shall be deemed vested as of such date (collectively, the “Separation Benefits”). You acknowledge that to the extent any of your stock options constitute “incentive stock options” within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), they shall be deemed modified for the purposes of Section 424 of the Code and, to the extent the exercise price thereof is lower than the fair market value of the Company’s common stock as of the date you execute this Letter Agreement, such options will no longer qualify as incentive stock options and you will lose the potentially favorable tax treatment associated with such options.

4.    Restrictive Covenants. Both during and after your employment you acknowledge your continuing obligations under that certain Proprietary Information and Invention Assignment Agreement (the “PIIA Agreement”) entered into by and between you and the Company on or about March 10, 2021 not to use or disclose any confidential or proprietary information of the Company and to refrain from certain solicitation activities, in each case as detailed in the PIIA Agreement. A copy of your PIIA Agreement is attached hereto as Exhibit C. You acknowledge that all such covenants remain in full force and effect pursuant to their terms, and that your continuing compliance with such obligations is a material condition to the Company’s agreement to enter into this Letter Agreement. As of the Separation Date, you will have executed and delivered to the Company the “Termination Certificate” attached as Appendix B to your PIIA Agreement. Following the Separation Date, you agree not to publish or disseminate, directly or indirectly, any statements, whether written or oral, that are or could be harmful to or reflect negatively on any of the Company or any of its affiliates, or that are otherwise disparaging of any of the Company’s, its affiliates or any of their past or present officers, directors, employees, advisors, agents, policies, procedures, practices, decision-making, conduct, professionalism or compliance with standards. In the event that following your Separation Date, the Company determines that during your employment with the Company and its affiliates, you engaged in conduct that would have constituted “Cause” for termination (as defined under your Employment Agreement with the Company effective on or about April 21, 2021) or you breached your obligations under this Section 4 or Section 7 (including your obligations under the PIIA Agreement), the Company shall have no further obligations under Section 3 and you will forfeit any stock options that remain outstanding pursuant to Section 3 and, to the extent permitted by applicable law, you shall pay the Company an amount equal to all proceeds received in connection with any sale or other disposition of any shares underlying your stock options, RSUs and any other equity awards.

Notwithstanding the foregoing, nothing herein shall restrict you from responding to a valid subpoena, nor shall you be prohibited from communicating with any government agency, including your right to communicate directly with the U.S. Securities and Exchange Commission, the U.S. Commodity Futures Trading Commission, the U.S. Department of Justice or similar agency, or to cooperate with or participate in any investigation conducted by such agency or to make any other disclosures that are protected under the whistleblower provisions of applicable law. For the avoidance of doubt, you do not need to notify or obtain the prior authorization of the Company to exercise any of the foregoing rights. Further, you understand that: (i) you will not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that is made in confidence to a federal, state, or local government official or to an attorney solely for the purpose of reporting or investigating a suspected violation of law; (ii) you will not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal; and (iii) if you file a lawsuit for retaliation by the Company for reporting a suspected violation of law, you may disclose trade secrets to your attorney and use the trade secret information in the court proceeding if you: (x) file any document containing the trade secret under seal; and (y) do not disclose the trade secret, except pursuant to court order.

5.    Arbitration. Without limiting your right to file Claims (as defined in the Release) with governmental agencies, you and the Company agree and desire that all disputes between you and the Company relating to or arising out of your employment with the Company or this Letter Agreement, other than Claims which you have effectively released pursuant to the Release and Claims that cannot, as a matter of law, be required to arbitrate (collectively, “Covered Claims”), will, to the fullest extent permitted by law, be resolved by final and binding arbitration in the county where you primarily worked for the Company as of the Separation Date. The arbitration will be conducted by a single, neutral arbitrator in accordance with the applicable arbitration rules (“Rules”) of the Judicial Arbitration and Mediation Service (“JAMS”) in effect when the dispute is submitted to arbitration, which can be found at www.jamsadr.com, or other rules mutually agreed upon in writing by the Company and you. The arbitrator shall be appointed as mutually agreed upon by you and the Company or, if no agreement can be reached, by JAMS pursuant to its Rules. The Federal Arbitration Act, 9 U.S.C. §§ 1 et seq. shall govern the interpretation and enforcement of this arbitration clause. The Company and you shall be entitled to more than minimal discovery and the arbitrator shall prepare a written decision containing the essential findings and conclusions on which the award is based so as to ensure meaningful judicial review of the decision. The arbitrator shall apply the same substantive law, with the same statutes of limitation and the same remedies that would apply if the claims were brought in a court of law. The Company shall pay all costs unique to arbitration, including without limitation arbitration administrative fees, arbitrator compensation and expenses, and costs of any witnesses called by the arbitrator. Unless otherwise ordered by the arbitrator under applicable law, you and the Company shall each bear your or its own expenses, such as expert witness fees and attorneys’ fees and costs. Nothing herein shall prevent you or the Company from seeking a statutory award of reasonable attorneys’ fees and costs, if any. This Section 5 shall be governed by and enforceable pursuant to the Federal Arbitration Act. This Section 5 is intended to be the exclusive method for resolving any and all Claims by you or the Company against each other for payment of damages under this Letter Agreement or relating to your employment; provided, however, that neither this Letter Agreement nor the submission to arbitration shall limit your or the Company’s right to seek provisional relief, including without limitation injunctive relief, in any court of competent jurisdiction.

6.    Waiver of Right to Jury Trial; Class Action Waiver. The Company and you understand and agree that this Letter Agreement constitutes a waiver of its and your right to a trial by court or jury of any Covered Claims. You understand and acknowledge that this Letter Agreement also constitutes a waiver of your right to bring any Covered Claim as part of or in connection with, or to participate with each person in or recover through, a class action lawsuit or claim. You and the Company agree that no Covered Claim shall be resolved by a court or jury trial, and no Covered Claim shall be brought as a class action.

7.    Cooperation. You shall assist and cooperate with the Company and its affiliates, (i) concerning reasonable requests for information about the business of the Company or its affiliates or your involvement and participation therein; (ii) in connection with the defense, prosecution or investigation of any claims or actions now in existence or which may be brought in the future against or on behalf of the Company or its subsidiaries or affiliates, including any proceeding before any arbitral, administrative, judicial, legislative, or other body or agency, including testifying in any proceeding to the extent such claims, actions, investigations or proceedings relate to services performed or required to be performed by you, pertinent knowledge possessed by you, or any act or omission by you; and (iii) and in connection with any investigation or review by any federal, state or local regulatory, quasi- or self-regulatory or self-governing authority or organization (including, without limitation, the SEC and FINRA) as any such investigation or review relates to services performed or required to be performed by you, pertinent knowledge possessed by you, or any act or omission by you. Your full cooperation shall include, but not be limited to, being available to meet and speak with board members, officers or employees of the Company, its affiliates and/or their counsel at reasonable times and locations, executing accurate and truthful documents, appearing at the Company’s request as a witness at depositions, trials or other proceedings without the necessity of a subpoena, and taking such other actions as may reasonably be requested by the Company and/or its counsel to effectuate the foregoing. In requesting such services, the Company will consider other commitments that you may have at the time of the request.

8.    Employee’s Representations. You represent and warrant that:

(a)As of your Separation Date, you will have returned to the Company all Company property in your possession, including, without limitation, all Confidential Information, laptops, cell phones, portable devices, software, keys, access badges or IDs, credit cards, thumb drives, equipment, supplies, records, files, handbooks, guidelines, materials, documents, and all other property belonging to the Company, whether in physical or electronic form, and all copies thereof.

13.    Execution in Counterparts. This Letter Agreement may be executed in counterparts with the same force and effectiveness as though executed in a single document. Facsimile and electronic signatures shall have the same force and effectiveness as original signatures.

14.     Section 409A.

(a) General. The intent of the parties is that the payments and benefits under this Letter Agreement comply with or be exempt from Section 409A of the Code and the Department of Treasury regulations and other interpretive guidance issued thereunder, including without limitation any such regulations or other guidance that may be issued after the date hereof, (“Section 409A”) and, accordingly, to the maximum extent permitted, this Letter Agreement shall be interpreted to be in compliance therewith. Notwithstanding any provision of this Letter Agreement to the contrary, if the Company determines that any compensation or benefits payable under this Letter Agreement may be subject to Section 409A, the Company shall work in good faith with you to adopt such amendments to this Letter Agreement or adopt other policies and procedures (including amendments, policies and procedures with retroactive effect), or take any other actions, that the Company determines are necessary or appropriate to avoid the imposition of taxes under Section 409A, including, without limitation, actions intended to (i) exempt the compensation and benefits payable under this Letter Agreement from Section 409A, and/or (ii) comply with the requirements of Section 409A; however, this Section 14 shall not create an obligation on the part of the Company to adopt any such amendment, policy or procedure or take any such other action, nor shall the Company (A) have any liability for failing to do so, or (B) incur or indemnify you for any taxes, interest or other liabilities arising under or by operation of Section 409A.

(b) Six-Month Delay. Notwithstanding anything to the contrary in this Letter Agreement, no compensation or benefits shall be paid to you during the six (6)-month period following your “separation from service” with the Company (within the meaning of Section 409A) if the Company determines that paying such amounts at the time or times indicated in this letter would be a prohibited distribution under Section 409A(a)(2)(B)(i) of the Code. If the payment of any such amounts is delayed as a result of the previous sentence, then on the first business day following the end of such six (6)-month period (or such earlier date upon which such amount can be paid under Section 409A without resulting in a prohibited distribution, including as a result of your death), the Company shall pay you a lump-sum amount equal to the cumulative amount that would have otherwise been payable to you during such period (without interest).

(c) Reimbursements. To the extent that any reimbursement of expenses or in-kind benefits constitutes “deferred compensation” under Section 409A, such reimbursement or benefit shall be provided no later than December 31st of the year following the year in which the expense was incurred. The amount of expenses reimbursed in one year shall not affect the amount eligible for reimbursement in any subsequent year. The amount of any in-kind benefits provided in one year shall not affect the amount of in-kind benefits provided in any other year.

To indicate your acknowledgment and agreement to the terms above, please date and sign the original of this Letter Agreement in the place indicated below no later than April 8, 2022.

The final wages referenced in Section 1 shall include your unpaid base salary accruing through the Separation Date; and

Such final wages will be paid out in accordance with the applicable plan documents, if any, and the applicable wage payment laws and will be subject to applicable taxes, garnishments and any other withholding required by law or authorized by you.
