LSP Advisors, as the investment manager of Gen IV, also has the power to direct the voting and disposition of the shares held by Gen IV. For Section 16 purposes, LSP Gen IV and LSP Advisors disclaim beneficial ownership over the shares reported herein, except to the extent of their pecuniary interest therein.</footnote>
        <footnote id="F2">Pursuant to a Purchase Agreement dated as of March 27, 2024 (the &quot;Series A-3 Purchase Agreement&quot;), on March 27, 2024 (the &quot;Issuance Date&quot;), Gen IV acquired from the Issuer 3,789 shares of Series A-3 Redeemable Convertible Preferred Stock of the Issuer, par value $0.0001 per share (the &quot;Series A-3 Preferred Shares&quot;) convertible into shares of Common Stock for an aggregate purchase price of approximately $3.7 million.</footnote>
        <footnote id="F3">Pursuant to the Certificate of Designations contemplated by the Series A-3 Purchase Agreement (the &quot;Series A-3 Certificate of Designations&quot;), the conversion price of the Series A-3 Preferred Shares is $6.83 per share and is subject to adjustment for stock splits, combinations, certain distributions or similar events in accordance with the terms of the Series A-3 Certificate of Designations.</footnote>
        <footnote id="F4">Subject to the terms and conditions of the Series A-3 Certificate of Designations, commencing on July 25, 2024, all or any portion of the Series A-3 Preferred Shares may be converted by Gen IV at any time into Common Stock at the Conversion Ratio. The &quot;Conversion Ratio&quot;, for each Series A-3 Preferred Share is the quotient of (i) the then-applicable liquidation preference (as determined in accordance with the Series A-3 Certificate of Designations) and (ii) the then-applicable conversion price.</footnote>
        <footnote id="F5">The Series A-3 Preferred Shares have no expiration date. If based on the Issuer's financial statements for any fiscal quarter and a reserve report as of the same date, as of such date: (x) the PDP PV-20 value (as determined in accordance with the Series A-3 Certificate of Designations) divided by (y) the number of outstanding shares of Common Stock, calculated on a fully diluted basis is equal to or exceeds 130% of the Conversion Price, then the Issuer may, from time to time until such time that the foregoing conditions are no longer satisfied or a Material Adverse Effect (as defined in the Series A-3 Purchase Agreement) has occurred since the date of the most financial statements that met the foregoing conditions, cause the conversion of all or any portion of the Series A-3 Preferred Shares into Common Stock using the then-applicable Conversion Ratio.</footnote>
        <footnote id="F6">The Series A-3 Preferred Shares are also subject to redemption by the Issuer at any time following the Issuance Date in accordance with the terms of the Series A-3 Certificate of Designations. In the event of a change of control transaction, the Series A-3 Preferred Shares are subject to redemption or conversion in accordance with the terms of the Series A-3 Certificate of Designations.</footnote>
