In connection with the closing of the Business Combination, the Reporting Person received a cash bonus of $400,000, in recognition of Reporting Person’s contributions to the Issuer.

In addition, pursuant to the terms of the Employment Agreement, and subject  to the approval of the board of directors or the Compensation Committee of the board of directors of the Issuer (“Compensation Committee”), on the effective date of the Issuer’s first filing of an S-8 registration statement with the U.S. Securities and Exchange Commission that occurs following the Closing Date, the Issuer will grant the Person restricted stock units to acquire 2,857,444 shares of Common Stock (the “Initial RSU Award”). To be eligible for the Initial RSU Award, the Reporting Person must still be employed by the Issuer when the Board or the Compensation Committee grants the Initial RSU Award. The Initial RSU Award will be subject to the terms and conditions of that certain 2022 Equity Incentive Plan (the “Plan”) and a restricted stock unit award agreement in a form approved by the Issuer. The Initial RSU Award will vest in accordance with the following schedule: (i) 50% of the total number of Initial RSU Awards will vest in substantially equal installments (rounded down, except for the final scheduled vesting installment) at the end of each month following the vesting commencement date over a period of 12 months and (ii) the remaining 50% of the total number of Initial RSU Awards will vest in in substantially equal installments (rounded down, except for the final scheduled vesting installment) at the end of each month following the vesting commencement date over a period of four years,with prongs (i) and (ii) occurring concurrently, such that, at the end of the 12-month period immediately following the vesting commencement date, 62.5% of the total number of Initial RSU Awards will have vested (subject to the Reporting Person’s Continuous Service (as defined in the Plan) on such vesting date). In the event of a Change in Control (as defined in the Plan), 100% of the then unvested shares subject to the Initial RSU Award shall vest immediately prior to the consummation of the Change in Control, subject to Reporting Person’s Continuous Service through such date. In the event that Reporting Person is terminated for Cause, as defined below, the Initial RSU Award will cease to vest as of the date of termination and the Reporting Person will have no further right, title or interest in the Initial RSU Award.

Registration Rights Agreement

On March 2, 2022, certain stockholders of Legacy Rigetti and the Issuer, including the Reporting Person (together, the “Holders”), entered into the Amended and Restated Registration Rights Agreement (the “Registration Rights Agreement”), pursuant to which the Issuer agreed that, within 30 calendar days after the Closing Date, the Issuer will file with the SEC (at the Issuer’s sole cost and expense) a registration statement registering the resale of certain securities held by or issuable to the Holders (the “Resale Registration Statement”), and the Issuer shall use commercially reasonable efforts to have the Resale Registration Statement declared effective as soon as practicable after the filing thereof.
