F1	The stock option vests as of 1/48 of the total shares monthly beginning on May 13, 2021 until fully vested, subject to the Reporting Person's provision of service to the Issuer on each vesting date.
F2	In a Form 4 filed on June 16, 2021, the reporting person reported that, on June 14, 2021, an employee stock option she had previously been granted was automatically converted into an employee stock option covering 36,880 shares of common stock of the Issuer, having an exercise price of $10.01 a share. It was subsequently determined that the exercise price of the option was less than the market price of the Issuer's common stock on the grant date, which was $12.25 a share. To avoid adverse tax consequences, the reporting person and the Issuer agreed to amend the option to provide that the option will have an exercise price of $12.25 a share. The amendment of the option is reported in this Form 4 as a cancellation of the original option and the grant of a replacement option.
