        <footnote id="F1">Each deferred stock unit (&quot;DSU&quot;) represents a contingent right to receive one share of Class A common stock.</footnote>
        <footnote id="F2">Represents annual grant of DSUs pursuant to the Company's 2021 Long-Term Incentive Plan in connection with the reporting person's service
as a non-employee director of the Company. DSUs vest immediately on the award grant date. Vested DSUs are converted into shares of Class
A common stock on a one-for-one basis upon the later of the reporting person's separation from service on the board or the first anniversary of
the grant date (the &quot;Settlement Date&quot;). If a change in control occurs before the Settlement Date, the settlement will occur on the control change
date. The reporting person does not have voting rights with respect to, but receives dividend equivalent payments on outstanding DSUs.</footnote>
        <footnote id="F3">Represents restricted stock units (&quot;RSUs&quot;) previously granted pursuant the Company's prior long-term incentive plans. RSUs have the same material terms as DSUs. No transaction occurred and is for informational purposes only.</footnote>
