Explanation of Responses:

1. Each restricted stock award ("RSU") represents a contingent right to receive 1 share of the Issuer's Common Stock upon settlement for no consideration.

2. The sale reported on this Form 4 represents shares sold by the Reporting Person to cover tax withholding obligations in connection with the vesting and settlement of RSUs. The sale was to satisfy tax withholding obligations to be funded by a "sell to cover" transaction and does not represent a discretionary transaction by the Reporting Person.

3. The transactions reported on this Form 4 were effected pursuant to a 10b5-1 trading plan adopted by the reporting person dated June 14, 2024.

4. 50% of the total restricted stock units vested on September 14, 2023 and September 14, 2024, subject to the Reporting Person's provision of service to the Issuer on each vesting date.

5. The stock option vests and becomes exercisable as to 25% of the shares subject to the option on July 15, 2021, and thereafter vests as to 1/48th of the shares in equal monthly installments, until such time as the option is 100% vested, subject to the continuing employment of the Reporting Person on each vesting date.

6. In addition to the remaining options to purchase 80,600 shares of common stock as set forth in Table II, the Reporting Person also holds additional options to purchase up to an aggregate of 263,040 shares of common stock, which options vest according to their terms.
