        <footnote id="F1">The disposition is due to withholding to cover taxes, as a result of the Reporting Person's election of net settlement of restricted stock units, which vest in accordance with their terms in two equal installments upon each of the first two six-month anniversaries of March 4, 2023, subject to the Reporting Person's continued employment or service with the Issuer through each such date. Each restricted stock unit represents a contingent right to receive one share of the Issuer's common stock, $0.001 par value per share (the &quot;Common Stock&quot;).</footnote>
        <footnote id="F2">On October 16, 2023, the Reporting Person filed a Form 4 which inadvertently reported the total amount of shares of Common Stock owned as 1,298,178. In fact, the total amount owned as of such date following the reported disposition of 205,321 was 1,698,178 .</footnote>
