Filing notes and footnotes

Explanation of responses 3 footnotes

Footnote F1

Each restricted stock unit ("RSU") represents a contingent right to receive one share of the Issuer's common stock upon vesting.

Footnote F2

The RSUs were granted on October 2, 2026 under the Issuer's 2022 Equity Incentive Plan, as amended (the "Plan"), as an annual RSU award to non-employee directors. One hundred percent (100%) of the RSUs will vest on the earlier of October 2, 2027 or the date of the Issuer's next annual meeting of stockholders following the grant date, subject to the Reporting Person's continued service as a non-employee director through the vesting date. Vested RSUs will be settled in shares of common stock. RSUs do not expire.

Footnote F3

The stock option was granted on October 2, 2026 under the Plan. The option vests as to one-half (1/2) of the underlying shares on the grant date, and as to the remaining one-half (1/2) on January 1, 2027, subject to the Reporting Person's continued service as a non-employee director through the applicable vesting date, with full acceleration of any then-unvested shares immediately prior to a Change in Control (as defined in the Plan).
