        <footnote id="F1">The price reported is the weighted average price of multiple trades at prices ranging from $2.5095 to $2.8916 per share, inclusive. The reporting person will provide, upon request by the SEC staff, the Issuer or a security holder of the Issuer, full information regarding the number of shares sold at each price within the reported range.  The convertible note converted at the same prices as these trades.</footnote>
        <footnote id="F2">Brad Shain may be deemed to have beneficial ownership of the shares held directly by CP BF Lending, LLC. Mr. Shain disclaims beneficial ownership of the securities reported herein, except to the extent of his pecuniary interest therein, and this report shall not be deemed an admission that he is the beneficial owner of such securities for purposes of Section 16 or any other purpose.</footnote>
        <footnote id="F3">On July 8, 2025, the Issuer effectuated a 1-for-10 reverse split of the Issuer's Class A common stock, resulting in proportionate adjustments to the number of shares beneficially owned by the Reporting Person. Accordingly, the securities reported herein have been adjusted to reflect the reverse stock split.</footnote>
        <footnote id="F4">On October 10, 2025, the Issuer and the Reporting Person agreed to amend the convertible note to, among other things, reduce the conversion price to a price equal to 95% of the price of the Class A common stock on the trading day immediately preceding delivery of any conversion notice, subject to a floor price of $2.50.  Accordingly, the convertible note reported herein has been adjusted to reflect the floor price.</footnote>
        <footnote id="F5">The maturity date of the convertible note will be February 19, 2027 or, if earlier, the date on which the consolidated convertible loan becomes due and payable pursuant to the terms of the convertible note or any other loan document.</footnote>
