        <footnote id="F1">On March 7, 2023, the reporting person filed a Form 4 that, due to an administrative error, reported an incorrect amount of securities withheld to cover taxes associated with the vest of restricted stock units on the first line of Table I. The amount originally reported was 897 shares of Common Stock, and the correct amount is included in this amendment.</footnote>
        <footnote id="F2">This amendment also corrects the amount of securities beneficially owned following the corrected transaction.</footnote>
