### Footnotes:

(1) Reflects the disposal of restricted stock units granted to the reporting person on March 31, 2023, which vested on March 31, 2026 and were settled with the reporting person in cash.

(2) Represents disposed shares, settled in cash, to satisfy withholding taxes applicable upon vesting on March 31, 2026 of the March 31, 2023 grant of restricted stock units under the 2022 Long Term Incentive Plan.

(3) KWELL Holdings, LP ("KHLP"), a Texas limited partnership, directly holds these securities. KWELL Group, LLC ("KWELL Group"), a Texas limited liability company, as General Partner of KHLP, has exclusive voting and investment control over the shares of Class A common stock held by KHLP, and therefore may be deemed to beneficially own such shares. Ladd Wilks, as manager of KWELL Group, may exercise voting and investment power over the shares of the Issuer's Class A common stock directly owned by KHLP. The Reporting Person disclaims beneficial ownership of all equity securities being reported herein except to the extent of his pecuniary interest therein.

(4) The Conversion Price may be adjusted from time to time in accordance with the Certificate of Designation of Series A Redeemable Convertible Preferred Stock, Exh. 3.1 to the Issuer's Form 8-K filed on October 2, 2023 ("CoD").

(5) Issuer's Series A convertible preferred stock has no expiration date as it is not redeemable at the option of holder and does not automatically convert into common stock on a specified date.

(6) In accordance with the CoD, following the first anniversary of the Issuance Date, each holder of Series A redeemable convertible preferred stock shall have the option from time to time to convert all or a portion of holder's shares of Series A redeemable convertible preferred stock into Class A common stock, par value $0.01 per share, at a Conversion Ratio equal to the quotient of (i) the Liquidation Preference as of the date of the conversion, which initially shall equal the original issue price per share of $1,000.00 and subsequently be adjusted as the result of any PIK Accrual and as otherwise set forth in the CoD, and (ii) the then applicable Conversion Price. The amount of underlying securities reported has been determined utilizing the Conversion Ratio calculated as of the transaction date.
