Explanation of Responses:

( 1 )Vitruvian II Woodford, LLC, a Delaware limited liability company ("Vitruvian"), is the record holder of 18,626,128 shares of common stock, par value $0.01 per share ("Common Stock") of Gulfport Energy Corporation (the "Issuer"). Vitruvian may also be deemed to be the beneficial owner of 5,225,989 shares of Common Stock held in a separate escrow account pursuant to the terms and conditions of the Purchase and Sale Agreement by and among the Issuer (together with the 18,626,128 shares of Common Stock, the "Vitruvian Shares"), Vitruvian and a subsidiary of the Issuer that may be released to Vitruvian in certain situations. ( 2 )Vitruvian is managed by its board of directors (the "Board"). QEM V, LLC ("QEM") is the sole general partner of Q-VEX II, LP ("Q-VEX"), which has the right to appoint a majority of the board of directors of Vitruvian Exploration II, LLC ("VEX"), which has the right to appoint a majority of the board of directors of Vitruvian Exploration II Holdings, LLC ("VEX Holdings"), which holds a majority of the capital interests of Vitruvian and has the right to appoint four of the nine directors of the Vitruvian Board (such directors, the "VEX Holdings Directors"). Certain actions of Vitruvian, including certain dispositions, require the approval of the VEX Holdings Directors. QEM, Q-VEX, VEX and VEX Holdings each disclaim beneficial ownership of the Vitruvian Shares in excess of their respective pecuniary interest in the securities. ( 3 )Any decision taken by QEM to vote, or to direct to vote, and to dispose, or to direct the disposition of, the Vitruvian Shares has to be approved by a majority of the members of the investment committee of QEM, which majority must include S. Wil VanLoh, Jr. Therefore, Mr. VanLoh may be deemed to share voting and dispositive power over the Vitruvian Shares and may also be deemed to be the beneficial owner of such securities. Mr. VanLoh disclaims beneficial ownership of such securities in excess of his pecuniary interest in the securities.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
