Explanation of Responses:
1. Same as Vesting Schedule; provided, however, that, if, as of any vesting date, the number of shares underlying the vested portion of the Option exceeds the number of shares available for issuance under the Plan (based on the then-current stockholder-approved share reserve thereunder (the EIP Reserve) and the number of shares subject to outstanding Stock Awards (as defined in the Plan) that were granted prior to the Grant Date specified above), then as to such excess shares, the Option shall not be exercisable until further stockholder approval is obtained for an adequate increase in the EIP Reserve.
2. Subject to the terms of the Option Agreement, one-twelfth (1/12th) of the shares subject to this option will vest on the last day of each calendar quarter following the Vesting Commencement Date, with the first vesting date being June 30, 2026, subject to your Continuous Service through each such vesting date, such that all shares subject to this option will be fully vested on March 31, 2029.
