Explanation of Responses:

( 1 )The Series D Preferred Stock has no voting rights and is not convertible into Class A common stock. The Issuer will redeem all outstanding shares of Series D Preferred Stock at the consummation of its initial public offering. ( 2 )Mr. Herz serves as the sole Managing Member of WhiteHawk Energy LLC, which in turn serves as the sole Managing Member of WhiteHawk Minerals LLC. In such capacity, Mr. Herz exercises sole voting and investment power over the shares of Class A common stock and Class B common stock held by WhiteHawk Minerals LLC and may therefore be deemed to beneficially own such shares. Mr. Herz disclaims beneficial ownership of such shares except to the extent of his pecuniary interest therein. ( 3 )Each common unit of WhiteHawk Income Operating Partnership L.P. ("Common Unit") held by WhiteHawk Minerals LLC may be redeemed or exchanged for one share of Class A common stock, and a corresponding number of Class B common stock will be cancelled for no consideration. The Common Units have no expiration date.
