        <footnote id="F1">The sales reported in this Form 4 were effected pursuant to a Rule 10b5-1 trading plan entered into for tax planning purposes, adopted by the reporting person on December 16, 2022, and which terminated on April 5, 2024.</footnote>
        <footnote id="F2">This Form 4 amends the original Form 4 filed by the Reporting Person on April 5, 2024, which inadvertently understated the number of shares disposed of on April 4, 2024. This amendment restates the number of shares disposed of on April 4, 2024 and the resulting amount of securities beneficially owned by the Reporting Person after the transaction that occurred on April 5, 2024.</footnote>
