Id Content
F1 The stock option (representing a right to purchase a total of 83,802 shares) vests as to 25% of the total shares on November 17, 2021, and thereafter vests as to the total shares quarterly until fully vested, subject to the Reporting Person's provision of service to the Issuer on each vesting date. In the Reporting Person's Form 4 filed on June 16, 2021, Footnote (1) inadvertently reported that the vesting of this stock option (as well as the other stock option beneficially owned by the Reporting Person that was reported in such Form 4) commenced on December 17, 2021.
