        <footnote id="F1">Represents 1,508 shares of the issuer's common stock underlying restricted stock units (&quot;RSUs&quot;) granted to the reporting person under the issuer's Long-Term Incentive Plan. Each RSU will entitle the reporting person to receive one share of the issuer's common stock when that unit vests. The units will vest in three successive annual installments upon the reporting person's completion of each year of service with the issuer over the three-year period measured from the date of grant, subject to accelerated vesting under certain prescribed circumstances.</footnote>
        <footnote id="F2">Represents 10,914 shares of the issuer's common stock and 4,037 shares of the issuer's common stock underlying RSUs that will vest and become issuable in accordance with their terms.</footnote>
        <footnote id="F3">Represents 342 shares of common stock withheld of the issuer in satisfaction of the applicable withholding taxes on certain shares of common stock that became issuable on January 2, 2020 pursuant to the terms of the January 2, 2018 and January 2, 2019 Restricted Stock Unit Issuance Agreements between the reporting person and the issuer. The issuable shares were previously reported as Table I securities at the time the restricted stock units were granted, and accordingly the issuance of those shares is not a reportable transaction on this Form 4.</footnote>
        <footnote id="F4">Represents 11,411 shares of the issuer's common stock and 3,198 shares of the issuer's common stock underlying RSUs which will vest and become issuable in accordance with their terms.</footnote>
