Item 2.03. Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

Gulfport is a party to that certain Credit Agreement (the “Credit Agreement”), dated as of March 11, 2005 (as amended by the First Amendment, dated March 20, 2007, and the Second Amendment, dated July 19, 2007), among Gulfport, each lender from time to time party thereto and Bank of America, N.A., as a lender and as administrative agent (“Bank of America”). In connection with Gulfport’s acquisition of strategic assets in West Texas in the Permian Basin, Gulfport entered into the Third Amendment to the Credit Agreement (the “Third Amendment”) with Bank of America on December 26, 2007, effective as of December 20, 2007. The Third Amendment provides for, among other things, an increase in Gulfport’s borrowing base under the revolving credit facility from $60.0 million to $90.0 million and a reduction in the Eurodollar interest rate, which Gulfport can elect to use at its option, of 0.75%. In addition, the maturity date was extended from March 31, 2009 to March 31, 2010. Gulfport agreed to pay a borrowing base increase fee of 0.50% of any increase of the borrowing base over the highest borrowing base previously in effect, payable on the day such increased borrowing base becomes effective.

Immediately prior to the entry into the Third Amendment, approximately $59.5 million was outstanding under the revolving credit facility, with an interest rate of 8.5%.

The foregoing description of the Third Amendment is qualified in its entirety by the full text of the documents attached hereto as exhibits 10.1 and 10.2 and incorporated by reference in this report.
