        <footnote id="F1">On October 15, 2021, the Reporting Person received these shares of the Issuer's common stock pursuant to an &quot;earn-out&quot; provision in Section 2.19(e)(ii) of that certain Agreement and Plan of Merger (the &quot;Merger Agreement&quot;) dated as of November 13, 2019 by and among the Issuer and the parties listed in the Merger Agreement.</footnote>
        <footnote id="F2">(continuation from footnote 1)  The Merger Agreement provided that if, after preparing the &quot;Closing Statement&quot; required by the Merger Agreement, the &quot;Post-Closing Adjustment&quot; (which generally relates to cash accounts, working capital and indebtedness at the &quot;Closing Date&quot;) was a positive number, the Issuer would be required to issue that number of new shares of common stock of the Issuer equal to the Post-Closing Adjustment divided by the &quot;Parent Stock Signing Price&quot; (i.e. $10.19), and to deposit such shares with the &quot;Exchange Agent&quot; for distribution to the &quot;Shareholders&quot; in accordance with their &quot;Shareholder Pro Rata Shares&quot; (as each such term is defined in the Merger Agreement), for no additional consideration.</footnote>
        <footnote id="F3">(continuation from footnote 2)  The Reporting Person's right to receive such additional shares in a non-market manner for no additional consideration became fixed and irrevocable on March 5, 2020, the effective date of the merger. Accordingly, by law, the date of acquisition of such earn-out shares for purposes of Section 16(b) is March 5, 2020, the effective date of the merger.</footnote>
        <footnote id="F4">The shares are held of record by BGV Opportunity Fund, for which the Reporting Person serves as an officer, director and general partner.</footnote>
