Explanation of Responses:

Id	Content
F1	Each restricted stock unit ("RSU") represents a contingent right to receive one share of the Issuer's common stock.
F2	25% of the RSUs will vest on February 1, 2027, and the remaining 75% of the RSUs will vest in equal installments on each quarterly anniversary thereafter, until such time as the RSUs are 100% vested, subject to the Reporting Person's provision of service to the Issuer on each vesting date. Shares of the Issuer's common stock will be delivered to the Reporting Person upon settlement.
F3	RSUs do not expire; they either vest or are canceled prior to the vesting date.
