        <footnote id="F1">On December 5, 2019 the reporting person was granted PSUs which vest only to the extent specified financial performance criteria are achieved and subject to the reporting person's continued service with the issuer, as follows: (i) 5/12 of the earned award vested on the first anniversary of the grant date and (ii) an additional 1/12 of the earned award will vest on the first day of each calendar quarter thereafter. The reporting person initially reported the number of shares that were eligible to be earned at target-level performance achievement. The performance criteria were achieved at a level below target; accordingly, the reporting person is eligible to earn 50.99% of the target number of units. The actual number of shares that vested on the reported transaction date was 50.99% of the at-target number of shares subject to vesting on that date and the number of PSUs beneficially owned following the reported transaction has been updated to reflect 50.99% of the target number of units.</footnote>
        <footnote id="F2">Performance Stock Units (&quot;PSUs&quot;) convert into common stock on a one-for-one basis.</footnote>
        <footnote id="F3">These shares were withheld to satisfy tax withholding obligations in connection with the vesting of PSU awards and stock unit awards granted to the reporting person on December 5, 2019, August 28, 2020 and September 3, 2020.</footnote>
