▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇

▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇

Dear ▇▇▇▇:

As you know, your employment with Rigetti Computing, Inc. (the “Company”) terminated effective December 15, 2022, and we desire to resolve any and all issues relating to your employment and the conclusion of your employment with the Company amicably and on mutually satisfactory terms. Accordingly, this letter sets forth the terms of the separation agreement (the “Agreement”) the Company is offering you to reach an amicable separation.

1.    SEPARATION. Your last day of work with the Company and your employment termination date was December 15, 2022 (the “Separation Date”). You are hereby deemed to have resigned, effective as of the Separation Date, from all positions, titles, duties, authorities, and responsibilities at or with the Company and its affiliates, and you agree to execute all additional documents and take such further steps as the Company may require to effectuate such resignation.

2.    ACCRUED OBLIGATIONS. Immediately following the Separation Date, you received your accrued but unpaid salary through the Separation Date. You confirm that you have submitted your final documented expense reimbursement statement reflecting all business expenses you incurred through the Separation Date, if any, for which you seek reimbursement. The Company will reimburse you for these expenses in accordance with the Company’s standard expense reimbursement policies. You shall also be entitled to vested benefits owed to you under any qualified retirement plan or health and welfare benefit plan in which you were a participant in accordance with applicable law and the provisions of such plan.

3.    SEVERANCE BENEFITS. If you timely sign and return this Agreement to the Company, allow it to become effective, and comply fully with your obligations hereunder, then in full satisfaction of any obligations for the Company to provide you with severance benefits under your Amended and Restated Employment Agreement, dated February 2, 2022 (the “Employment Agreement”), the Company will provide you with the following severance benefits (the “Severance Benefits”):

(a)    Severance Payment. The Company shall pay you as severance $446,000, which is an amount equal to twelve (12) months of your base salary in effect as of the Separation Date (“Severance Payment”). The Severance Payment will be paid in equal installments on the Company’s normal payroll schedule following the Separation Date, with the first payment beginning within sixty (60) days following the Separation Date (but no earlier than the Effective Date) (such date, the “Severance Pay Commencement Date”), and the remaining installments occurring on the Company’s regularly scheduled payroll dates thereafter; provided that on the Severance Pay Commencement Date, the Company will pay in a lump sum the aggregate amount

of the cash severance payments that the Company would have paid you through such date had the payments commenced on the Company’s first regularly scheduled payroll date after the Separation Date.

(b)    COBRA Premium Payments. If you timely elect continued coverage under COBRA for you and your covered dependents under the Company’s group health plans following the Separation Date, then the Company shall pay the COBRA premiums necessary to continue you and your covered dependents’ health insurance coverage in effect for you (and your covered dependents) on the Separation Date until the earliest of: (i) twelve (12) months following the termination date; (ii) the date when you become eligible for substantially equivalent health insurance coverage in connection with new employment or self-employment; or (iii) the date you cease to be eligible for COBRA continuation coverage for any reason, including plan termination (such period from the Separation Date through the earlier of (i)-(iii), the “COBRA Payment Period”). Notwithstanding the foregoing, if at any time the Company determines that its payment of COBRA premiums on your behalf would result in a violation of applicable law (including, but not limited to, the 2010 Patient Protection and Affordable Care Act, as amended by the 2010 Health Care and Education Reconciliation Act), then in lieu of paying COBRA premiums pursuant to this section, the Company shall pay you on the last day of each remaining month of the COBRA Payment Period, a fully taxable cash payment equal to the COBRA premium for such month, subject to applicable tax withholding, for the remainder of the COBRA Payment Period. Nothing in this Agreement shall deprive you of your rights under COBRA or ERISA for benefits under plans and policies arising under your employment by the Company.

4.    EQUITY AWARDS. Under the terms of your equity award agreement and the applicable plan documents, vesting of any of your equity awards will cease as of the Separation Date. Your right to exercise any vested shares, and all other rights and obligations with respect to your equity awards, will be as set forth in your award agreement, grant notice and applicable plan documents.

5.    OTHER COMPENSATION OR BENEFITS. By executing this Agreement, you acknowledge and agree that the Company’s obligations to provide you with any severance benefits or any other payments are hereby extinguished (except for the benefits described in this Agreement). You further expressly acknowledge and agree that the Severance Benefits, and other benefits provided herein, are in full and complete satisfaction of the Company’s obligations, if any, to pay you severance benefits or any other payments pursuant your Employment Agreement, or any other agreements, plans or policies, and that this Agreement hereby supersedes and extinguishes any severance benefits you are or could be eligible to receive under your Employment Agreement, or any other employment agreement, plan, policy or other agreement applicable to you. You also acknowledge that, except as expressly provided in this Agreement, you have not earned and will not receive from the Company any additional compensation, severance, or benefits on or after the Separation Date, with the exception of any vested right you may have under the express terms of a written ERISA-qualified benefit plan

You agree that you will not voluntarily (except in response to legal compulsion or as permitted under Section 6(e) of this Agreement) assist any person in bringing or pursuing any proposed or pending litigation, arbitration, administrative claim or other formal proceeding against the Released Parties in connection with a claim that, if brought by you individually, would have been released under the terms of this Agreement.

11.    COOPERATION. You agree to provide reasonable cooperation to the Company in connection with its actual or contemplated defense, prosecution, or investigation of any claims or demands by or against third parties, or other matters arising from events, acts, or failures to act that occurred during the period of your employment by the Company. Such cooperation includes, without limitation, making yourself available to the Company upon reasonable notice, without subpoena, to provide complete, truthful and accurate information in witness interviews, depositions, and trial testimony. The Company will reimburse you for reasonable out-of-pocket expenses you incur in connection with any such cooperation (excluding foregone wages, salary, or other compensation) and will make reasonable efforts to accommodate your scheduling needs and for more than de minimis service, you and the Company will agree on a mutually agreeable per diem rate.

13.    REPRESENTATIONS. You hereby represent that you have: been paid all compensation owed and for all hours worked; received all leave and leave benefits and protections for which you are eligible pursuant to the Family and Medical Leave Act, the California Family Rights Act, or otherwise; and not suffered any on-the-job injury for which you have not already filed a workers’ compensation claim.

14.    [RESERVED]

15.    DISPUTE RESOLUTION. You and the Company recognize that litigation in federal or state courts or before federal or state administrative agencies of disputes arising out of your employment with the Company or out of this Agreement, or your termination of employment, may not be in the best interests of either you or the Company, and may result in unnecessary costs, delays, complexities, and uncertainty. Except where prohibited by law, you and the Company agree that any dispute between the parties arising out of or relating to the negotiation, execution, performance or termination of this Agreement or your employment, including, but not limited to, any claim arising out of this Agreement, claims under Title VII of the Civil Rights Act of 1964, as amended, the Civil Rights Act of 1991, the Age Discrimination in Employment Act of 1967, the Americans with Disabilities Act of 1990, Section 1981 of the Civil Rights Act of 1966, as amended, the Family Medical Leave Act, the Executive Retirement Income Security Act, and any similar federal, state or local law, statute, regulation, or any common law doctrine, whether that dispute arises during or after employment, shall be settled by binding arbitration in accordance with the National Rules for the Resolution of Employment Disputes of the American Arbitration Association. The location for the arbitration shall be in Alameda County, California. Any award made by such panel shall be final, binding and conclusive on the parties for all purposes, and judgment upon the award rendered by the arbitrators may be entered in any court having jurisdiction thereof. The arbitrators’ fees and expenses and all administrative fees and expenses associated with the filing of the arbitration shall be borne by the Company; provided however, that at your option, you may voluntarily pay up to one-half the costs and fees. You and the Company acknowledge and agree that our obligations to arbitrate under this section survive the termination of this Agreement and continue after the termination of the employment relationship between you and the Company. You and the Company each further agree that the arbitration provisions of this Agreement shall provide each party with its exclusive remedy, and each party expressly waives any right it might have to seek redress in any other forum, except as otherwise expressly provided in this Agreement. By election arbitration as the means for final settlement of all claims, you and the Company hereby waive their respective rights to, and agree not to, sue each other in any action in a Federal, State or local court with respect to such claims, but may seek to enforce in court an arbitration award rendered pursuant to this Agreement. You and the Company specifically agree to waive their respective rights to a trial by jury, and further agree that no demand, request or motion will be made for trial by jury.
