Explanation of Responses:

Id	Content
F1	The sales reported on this Form 4 represent shares sold by the Reporting Person to cover tax withholding obligations in connection with the vesting and settlement of restricted stock units ("RSUs"). The sales were to satisfy tax withholding obligations to be funded by a "sell to cover" transaction.
F2	The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $25.38 to $25.57, inclusive. The Reporting Person undertakes to provide to the Issuer, any securityholder of the Issuer or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the range set forth in this footnote 2 to this Form 4.
F3	Each RSU represents a right to receive one share of the Issuer's Class A Common Stock at the time of vesting for no consideration. On January 29, 2021, the Reporting Person was granted 36,174 RSUs. Such RSUs were previously reported in Table II on a Form 4 filed with the Securities and Exchange Commission on February 2, 2021.
F4	The RSUs vested as to 1/8 of the total shares on June 30, 2021, and 1/16th of the total shares will vest quarterly thereafter, subject to the Reporting Person's provision of service to the Issuer on each vesting date.
F5	RSUs do not expire; they either vest or are canceled prior to the vesting date.
