Explanation of Responses:

Id	Content
F1	Restricted stock units ("RSUs") convert into common stock on a one-for-one basis.
F2	The sale reported on this Form 4 represents an Issuer mandated sale by the Reporting Person to satisfy tax withholding obligations in connection with the vesting and settlement of RSUs; it does not represent a discretionary trade by the Reporting Person. Pursuant to the Issuer's equity incentive plan, an award recipient's tax withholding obligations must be funded by a "sell to cover" transaction.
F3	1/4 of the RSUs vested on June 15, 2022, and the remainder vested or vests as to 1/4 of the total award in annual installments thereafter, subject to the Reporting Person's continued service to the Issuer on each vesting date.
F4	These restricted stock units do not expire; they either vest or are cancelled prior to the vesting date.
