[F2] The award shall vest as to 1/12 of the total award quarterly on each of August 15th, November 15th, March 1st, and May 15th. Once time-vested, the restricted stock units will be settled for shares of the Issuer's Class A Common Stock during calendar year 2031 on a date to be determined by the Issuer.
[F3] (Continued from footnote (2)) Notwithstanding the aforementioned deferral period, once vested, deferred stock units will automatically settle earlier upon the earliest to occur of: (i) the reporting person's death, disability, or separation from service with the Issuer, (ii) a Change in Control (as defined under the Issuer's 2021 Amended and Restated Equity Incentive Plan) or (iii) the occurrence of an "unforeseeable emergency" (as defined under Section 409A of the Internal Revenue Code). The events described in subclauses (i), (ii), and (iii) of the preceding sentence are referred to herein as the "Extraordinary Settlement Events." If an Extraordinary Settlement Event occurs before the applicable vesting date, then settlement will occur instead on the applicable vesting date.
[F4] These restricted stock units do not expire; they either vest or are cancelled prior to the vesting date.
