( 2 )(continued from Footnote 1) The Tender and Support Agreements were entered into in connection with the Agreement and Plan of Merger, dated May 8, 2025, by and among Parent, Merger Sub, and the Issuer. WhiteHawk Income Corporation, Parent, Merger Sub, and Mr. Herz, as the Chief Executive Officer of WhiteHawk Income Corporation (together, the "Reporting Persons") exercise voting power in limited situations over the Subject Shares through the grant of an irrevocable proxy by each of the Supporting Stockholders in the Tender and Support Agreements and, as such, may be deemed to have beneficial ownership of such shares. The Reporting Persons disclaim beneficial ownership over the Subject Shares, except to the extent of their pecuniary interest therein, if any. ( 3 )Consists of 946,606 shares of common stock of the Issuer that are held directly by WhiteHawk - Equity Holdings, LP ("WhiteHawk LP," and such shares, the "Held Shares"). WhiteHawk - Equity Holdings GP, LLC ("WhiteHawk GP") is the general partner of WhiteHawk LP and retains the sole and exclusive right to manage and control any and all matters in connection with the voting and disposition of any securities held by WhiteHawk LP. Whitehawk Energy, LLC ("WhiteHawk Energy") is the sole member of WhiteHawk GP, and Mr. Herz is the President, Chief Executive Officer, and Managing Member of WhiteHawk Energy. Thus, Mr. Herz may be deemed to have indirect beneficial ownership of the Held Shares.
