        <footnote id="F1">Represents shares withheld to pay taxes applicable to vesting of restricted stock units.</footnote>
        <footnote id="F2">On March 3, 2023, the reporting person filed a Form 4 that, in the second transaction disclosed, contained an erroneous figure in the &quot;Amount&quot; sub-column of Column 4, entitled &quot;Securities Acquired (A) or Disposed Of (D).&quot; The erroneous amount was the total number of restricted stock units that vested on March 1, 2023, rather than just the shares withheld to pay taxes on such vesting. The correct amount of shares disposed of is 60,040 shares and, therefore, the correct figure in Column 5, entitled &quot;Amount of Securities Beneficially Owned Following the Reported Transaction(s),&quot; is 15,717,897 shares. This Form 4/A is filed to furnish the correct amounts.</footnote>
