        <footnote id="F1">This Form 4 is filed to report a grant of restricted stock units (&quot;RSUs&quot;) pursuant to the Issuer's 2014 Omnibus Equity Incentive Plan (the &quot;Plan&quot;). The RSUs will vest on the later of three years from the date of grant or the grantee reaching the age of 65 years.  The Issuer, in its sole discretion, may settle the RSUs in the form of cash, shares of the Issuer's Class A Common Stock or a combination of both. This Form 4 includes the reporting person's balance in the Supplemental Executive Retirement Plan (&quot;SERP&quot;) that is hypothetically invested 100% in the Issuer's Class A Common Stock on the date of grant.</footnote>
        <footnote id="F2">The investment return on contributions in the SERP is generally equal to the earnings and losses that would occur if 100% of the contributions were invested in the Issuer's Class A Common Stock on the date of grant. Vested balances in the SERP are settled in the Issuer's sole discretion in the form of cash, shares of the Issuer's Class A Common Stock or a combination of both.</footnote>
        <footnote id="F3">Represents the aggregate number of RSUs allocated to the reporting person under the SERP as of the date of grant based on the Fair Market Value defined as the mean between the highest and lowest quoted selling price of a share of the Issuer's Class A Common Stock on July 21, 2022.</footnote>
        <footnote id="F4">The vested balance in the reporting person's SERP account is payable in cash, Class A Common Stock or a combination of both following a Participant's termination of service due to death, Disability, retirement no less than 3 years from the initial date of participation in the Plan or a reason approved by the Board in accordance with Article 2.2 of the Plan.</footnote>
        <footnote id="F5">The number of RSUs allocated to the reporting person under the SERP is determined by dividing the amount of deferred eligible compensation by the Fair Market Value of a share of the Issuer's Class A Common Stock on each applicable award date.</footnote>
