Explanation of Responses:

Id	Content
F1	Restricted stock units convert into common stock on a one-for-one basis.
F2	Represents the number of shares required to be sold by the Reporting Person to cover tax withholding obligations in connection with the vesting of RSUs. These sales are mandated by the Issuer's election under its equity incentive plans to require the satisfaction of a tax withholding obligation to be funded by a "sell to cover" transaction and do not represent discretionary trades by the Reporting Person.
F3	Each restricted stock unit represents a contingent right to receive one share of Issuer's common stock.
F4	The RSUs vests as to one-third (1/3) of the total restricted stock units in equal annual installments beginning on October 6, 2021, until fully vested subject to the reporting person's provision of service to the Issuer on each vesting date.
