Item 1.01 Entry into a Material Definitive Agreement.

On October 16, 2009, GMX Resources Inc. (the "Company") entered into a Purchase Agreement (the "Purchase Agreement") with Kinder Morgan Endeavor LLC ("KME"), an affiliate of Kinder Morgan Tejas Pipeline LLC and Kinder Morgan Energy Partners, L.P. Pursuant to the Purchase Agreement, immediately prior to the closing of the transactions described therein, the Company will contribute, and cause its wholly-owned subsidiary, Endeavor Pipeline Inc. ("Endeavor"), to transfer, materially all of the assets comprising the Company's natural gas gathering business, including high and low pressure steel natural gas pipelines, compression and related equipment, inventory, certain contract rights, certain permits and certain interests in real property of the Company used for pipeline operations, to a new entity, Endeavor Gathering LLC (the "JV Entity").

At the closing of the transactions contemplated in the Purchase Agreement, the Company will sell a 40% membership interest in the JV Entity to KME in exchange for $36 million. The Company will retain the remaining 60% membership interest in the JV Entity. According to the agreement that will govern the JV Entity following closing, KME will be entitled to receive 80% of the cash distributions from the JV Entity until KME has received a return of its cumulative investment in the JV Entity, at which point cash distributions by the JV Entity will be paid 60% to the Company and 40% to KME in proportion to their membership interests. Additionally, upon the closing of the transactions described in the Purchase Agreement, the Company has committed to activate a second drilling rig on its oil and natural gas properties in Harrison and Panola Counties, Texas, and to keep at least two rigs active and drilling these properties for a three-year period.

Closing of the transactions contemplated in the Purchase Agreement is subject to the satisfaction of customary closing conditions, including the requirement to obtain certain consents from the Company's secured lenders and the release of liens held by such secured lenders on the assets to be transferred to the JV Entity. The Company expects closing to occur in early November 2009.

The foregoing description of the Purchase Agreement is qualified in its entirety by reference to the copy of the Purchase Agreement filed as an exhibit to this Report.
