(4) 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.

(5) The RSUs vest as to 1/4 of the total shares on August 15, 2024, 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.
