        <footnote id="F1">Transaction reported is a grant of 26,489 restricted stock awards representing shares of Series A Cumulative Perpetual Preferred Stock, par value $0.001 per share, of the issuer (&quot;Preferred Stock&quot;), which were approved by the Compensation Committee. The shares of Preferred Stock will vest 33% on June 1, 2025, 33% on June 1, 2026, and 34% on June 1, 2027, in each case subject to the reporting person remaining in the service of the issuer on each such vesting date.</footnote>
        <footnote id="F2">Transaction reported is a grant of 35,294 restricted stock awards representing shares of Common Stock, which were approved by the Compensation Committee. The shares of Common Stock will vest 100% upon the reporting person's separation from the issuer.</footnote>

    </footnotes>

    <remarks>On October 13, 2023, the issuer effected a reverse stock split (the &quot;Reverse Stock Split&quot;) of outstanding shares of its common stock, par value $0.001 per share (&quot;Common Stock&quot;), pursuant to which every 25 shares of Common Stock were automatically reclassified into one new share of Common Stock. Proportionate adjustments were made to the issuer's outstanding equity awards as well as the exercise, grant and acquisition prices of such equity awards, as applicable. Accordingly, all amounts of securities reported on this Form 4 have been adjusted to reflect the Reverse Stock Split.</remarks>
