        <footnote id="F1">Represents 1,209 shares of the common stock underlying restricted stock units (&quot;RSUs&quot;) granted to the reporting person under the issuer's Long-Term Incentive Plan. Each RSU entitles the reporting person to receive one share of common stock upon vesting of the RSU. The RSUs will vest in three annual successive installments upon the completion of the reporting person's each year of service with the issuer for the three-year period measured from the date of grant, subject to accelerated vesting under certain prescribed circumstances.</footnote>
        <footnote id="F2">Represents 1,899 shares of the issuer's common stock and 3,201 shares of the issuer's common stock underling restricted stock units which will vest and become issuable in accordance with their terms.</footnote>
        <footnote id="F3">Represents 335 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 4, 2021 pursuant to the terms of the January 2, 2018, January 2, 2019, and January 2, 2020 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 2,383 shares of the issuer's common stock and 2,382 shares of the issuer's common stock underling restricted stock units which will vest and become issuable in accordance with their terms.</footnote>
