        <footnote id="F1">Shares of common stock of the Issuer (the &quot;Shares&quot;) sold pursuant to an agreement between the Issuer and the trustees of the Reporting Person (the &quot;Trustees&quot;), at a purchase price of $25.95 per Share, which per Share price was agreed upon between the Issuer and the Trustees on February 11, 2026, based on the range of intraday trading prices for the Issuer's common stock on the NASDAQ Stock Exchange on that date. The sale of the Shares closed on February 26, 2026. The Shares were sold for investment portfolio diversification purposes of the Reporting Person.</footnote>
        <footnote id="F2">The Reporting Person has three Trustees. Any action by the Reporting Person with respect to the shares of Common Stock may be taken only by majority vote of the Trustees and, therefore, no Trustee individually has voting or dispositive power with respect to the shares.</footnote>
    </footnotes>

    <remarks>Solely for purposes of Section 16 of the Securities Exchange Act of 1934, as amended, the Reporting Person may be deemed to be a director-by-deputization by virtue of the Reporting Person's one-time contractual right to designate a Trustee for appointment to the board of directors of the Issuer pursuant to the Investor Agreement by and between the Trustees and the Issuer, dated November 25, 2024, under which the Issuer appointed one of the Trustees as a director of the Issuer, effective May 1, 2025, to serve in accordance with the corporate governance guidelines and standards applicable to all Issuer directors.</remarks>
