        <footnote id="F1">On March 18, 2025, the Reporting Person filed a Form 4 to report an award of 3,062 common stocks granted on March 14, 2025.  But due to administrative error they were reported as being held indirectly by Joint Spousal Trust. This Form 4/A amends the Form 4 filed on March 18, 2025, so that such Form 4, as amended, reflects the 3,062 common stocks directly held by the Reporting Person.</footnote>
        <footnote id="F2">The price reported in Column 4 has been rounded to the nearest cent.</footnote>
        <footnote id="F3">The common stocks which due to administrative error were previously reported as being held directly, are held indirectly by Joint Spousal Trust.</footnote>
        <footnote id="F4">The Reporting Person is a trustee of the Joint Spousal Trust. The Reporting Person and his spouse are the sole beneficiaries of the Joint Spousal Trust.</footnote>
