Explanation of Responses:

Id	Content
F1	Each restricted stock unit ("RSU") represents a contingent right to receive 1 share of the Issuer's Class A Common Stock upon settlement for no consideration.
F2	The sale reported on this Form 4 represents shares sold by the Reporting Person to cover tax withholding obligations in connection with the vesting and settlement of RSUs. The sale was to satisfy tax withholding obligations to be funded by a "sell to cover" transaction and does not represent a discretionary transaction by the Reporting Person.
F3	1/16th of the total shares vested on October 25, 2021 and November 10, 2021, and thereafter vests as to 1/16th of the total shares underlying the award in quarterly installments until fully vested on May 10, 2025, subject to the Reporting Person's continued service to the Issuer on each vesting date.
