F1	Grant to the Reporting Person of a stock option under the 2020 Equity Incentive Plan (the Plan), 1/4 of the total number of shares of stock subject to the option vest on May 10, 2022.

In the event of a change in control of the Issuer, 50% of the unvested options shall become fully and immediately vested upon the closing date of such change in control, provided, however, that on the earlier of (i) the one-year anniversary of the closing date or (ii) involuntary termination, any options that remain unvested on such earlier date shall become fully and immediately vested.
