        <footnote id="F1">This filing amends the Form 4 filed by the Reporting Person on June 16, 2025 (the &quot;Original Filing&quot;).  In the Original Filing, due to an administrative mistake, the Reporting Person's beneficial ownership indicated 1,405 shares of the Issuer's common stock were indirectly owned through a Rabbi Trust.  In actuality, all shares are owned directly and this amendment is being filed to report the correct nature of the beneficial ownership.  No other changes have been made to the information contained in the Original Filing.</footnote>
