        <footnote id="F1">Represents a matching Stock Option granted to the Reporting Person in connection with the Elite Program under the Issuer's Equity and Long-Term Incentive Plan. If at any time starting on February 15, 2020 through February 15, 2024, the Reporting Person owns fewer than 451,263 shares of Class A Common Stock but more than 270,758, a pro rata portion of the matching Stock Option will be forfeited.  If at any time starting on February 15, 2020 through February 15, 2024, the Reporting Person owns fewer than 270,758, the entire matching Stock Option will be forfeited.</footnote>
        <footnote id="F2">Upon vesting, each Restricted Stock Unit settles for one share of Class A Common Stock of the Issuer. Subject to certain vesting conditions and exceptions, the Restricted Stock Units vest as follows: 60% on February 15, 2022, 20% on February 15, 2023 and 20% on February 15, 2024.</footnote>
