September 30, 2013

This term sheet (the “Term Sheet”) describes certain of the principal terms of a proposed restructuring (the “Restructuring”) for GMX Resources Inc. (“GMXR”), Diamond Blue Drilling Inc. (“Diamond Blue”) and Endeavor Pipeline Inc. (“Endeavor,” and together with GMXR and Diamond Blue, the “Debtors”) to be implemented pursuant to a joint plan of reorganization (the “Plan”) consistent in all material respects with this Term Sheet to be filed in the Debtors’ pending chapter 11 cases (the “Chapter 11 Cases”) in the United States Bankruptcy Court for the Western District of Oklahoma (the “Bankruptcy Court”). Capitalized terms used and not defined herein shall have the meanings ascribed to them in the Plan Support Agreement (the “PSA”).


Implementation of Restructuring		The Restructuring set forth in this Term Sheet shall be effectuated through (i) the execution of the PSA by the Debtors, the Official Committee of Unsecured Creditors appointed in the Debtors’ Chapter 11 Cases (the “Creditors’ Committee”) and certain holders of Series A and Series B Senior Secured Notes due 2017 (collectively, the “Senior Secured Notes,” with the holders of such Notes being referred to herein as the “Senior Secured Noteholders”) that are referred to in the PSA as the “Consenting Senior Secured Noteholders” and that comprise the steering committee of Senior Secured Noteholders (the “Steering Committee”) and (ii) the solicitation and confirmation of the Plan, which shall be in all material respects consistent with this Term Sheet and the PSA.

		The parties to the PSA and their respective advisors shall negotiate in good faith and use all deliberate speed to negotiate the definitive documentation to implement the Restructuring consistent with the terms described in this Term Sheet and any related documentation, including without limitation, the PSA, the Plan and the disclosure statement describing the Plan (the “Disclosure Statement”).


Plan Financing		The maturity date for the debtor-in-possession financing facility (the “DIP Financing”) approved by Bankruptcy Court order dated May 6, 2013 [Docket No. 323] (as the same may be amended or modified from time to time, the “Final DIP Order”) shall be extended so that it may continue to be used by the Debtors for the purposes set forth in, and in accordance with the terms of, the DIP Credit Agreement and the Final DIP Order and to provide cash sufficient for the Debtors to make distributions to creditors under the Plan in accordance with this Term Sheet.

Treatment of Administrative and Priority Claims		Upon the effective date of the Plan, the Debtors shall pay all administrative and priority claims as required by section 1129 of the Bankruptcy Code, including but not limited to the superpriority adequate protection claims (if any) of the holders of Senior Secured Noteholder Claims (as defined below), all fees and expenses of the Steering Committee (as set forth under the “Fees and Expenses” section below) and the DIP Lenders and their professionals as required under the Final DIP Order. If the class of holders of general unsecured claims votes to accept the Plan, neither the Steering Committee nor its professionals, the DIP Lenders and their professionals, nor any holder of an administrative or priority claim shall have any claim against, or recourse to, the Litigation Trust or the Cash Distribution (each as defined below) for payment of such claims. If the class of holders of general unsecured claims votes to reject the Plan, upon the Effective Date, the Senior Secured Noteholders on account of their superpriority adequate protection claims (if any) shall receive interests in the Litigation Trust that are senior to those granted to holders of general unsecured claims to the extent such claims are not otherwise paid in full in cash on the Effective Date.

If the class of holders of general unsecured claims votes to reject the Plan, upon the Effective Date, the holders of DIP Financing Claims shall receive payment in full on account of all DIP Financing Claims either from (i) the estates through issuance of interests in the Litigation Trust which are senior to those granted to the Senior Secured Noteholders on account of their superpriority adequate protection claims (if any) and the holders of general unsecured claims and/or (ii) any Exit Financing.

Treatment of the Senior Secured Noteholder Claims		The claims arising under or related to the Senior Secured Notes and/or the Senior Secured Indenture (the “Senior


		Secured Noteholder Claims”) have been allowed by order of the Bankruptcy Court in the aggregate amount of $402,363,309.00 (exclusive of post-petition interest, fees and expenses) consisting of (i) principal and accrued interest owing on the First Lien Notes as of the Petition Date in the amount of $336,276,571.00 and (ii) the Applicable Premium (as defined in the Senior Secured Indenture) in the amount of $66,086,738.00. The secured portion of the Senior Secured Noteholder Claims shall be allowed in the amount of $338,000,000, the value of the Collateral (as defined in the Senior Secured Indenture) (the “Senior Secured Noteholder Secured Claim”) as determined at the auction held on August 28, 2013 for substantially all of the Debtors’ assets. The Senior Secured Noteholders hold an unsecured deficiency claim in the amount of $64,363,309.00 (the “Deficiency Claim”), the remaining balance of the debt outstanding as of the Petition Date under the Senior Secured Notes.

		Upon the Effective Date of the Plan, the holders of Senior Secured Notes shall receive, in full and final satisfaction of the Senior Secured Noteholder Secured Claim, 100% of the equity in reorganized GMXR and/or equity interests in an affiliate (the “New Equity Interests”) (provided that the issuance of the New Equity Interests shall be subject to dilution by any equity issued to holders of the DIP Financing Claims and pursuant to the Management Incentive Plan (as defined below)) and new notes in the aggregate principal amount and with additional terms to be mutually agreed upon by the Debtors and the Steering Committee.

		In addition, all fees and expenses of the Steering Committee (including, without limitation, the payment of all reasonable fees and expenses of its legal and financial advisors) shall be paid on the effective date of the Plan (the “Effective Date”).

Treatment of Equity Interests		Upon the Effective Date of the Plan, all equity interests of any kind in the Debtors, including common and preferred stock, options, warrants, and other agreements or rights to acquire the same (including any arising under or in connection with any employment agreement or any incentive plan or any benefit plan or the like) (collectively, the “Old Equity”) existing prior to the consummation of the Restructuring, shall be cancelled upon the Effective Date without any further action. All outstanding equity interests in GMXR’s subsidiaries and affiliates, including Diamond Blue and Endeavor, shall be reinstated upon the Effective Date.

		The class of the Debtors’ equity interests shall be impaired under the Plan and holders of equity interests shall be deemed to have rejected the Plan pursuant to section 1126(g) of the Bankruptcy Code.

The Litigation Trust		A litigation trust (the “Litigation Trust”) shall be established under the Plan, for the benefit of (i) if the class of holders of general unsecured claims votes to accept the Plan, holders of allowed general unsecured claims against the Debtors that are entitled to share in the distributions to such holders and (ii) if the class of holders of general unsecured claims does not vote to accept the Plan (a) the DIP Lenders on account of their DIP Financing Claims, (b) the Senior Secured Noteholders on account of their superpriority adequate protection claims (if any) and (c) holders of allowed general unsecured claims.

		The potential causes of action held by the Debtors and their respective estates listed on the attached Schedule A (the “Schedule A Claims”) shall be transferred to the Litigation


		Trust on the Effective Date of the Plan for the benefit of the Litigation Trust beneficiaries; provided, that in no event shall the Litigation Trustee (as defined below) on behalf of the Litigation Trust pursue any causes of action against the DIP Lenders, the Consenting Senior Secured Noteholders, the Steering Committee, U.S. Bank, National Association, as indenture trustee under the Senior Secured Indenture, Cantor Xxxxxxxxxx Securities, as collateral and administrative agent under the DIP Credit Agreement, or any of their respective officers, directors, managers, employees and advisors (whether or not such persons are released under the Plan).

Tax Related Issues (Structuring & Otherwise)		The parties shall use good-faith efforts to structure the Restructuring to the maximum extent possible in a tax-efficient


		and cost-effective manner for the benefit of the parties to the PSA. Notwithstanding the forgoing, the Steering Committee shall have the sole discretion over the structure to the extent it relates to the treatment of Senior Secured Noteholder Claims so long as the treatment of the class of holders of general unsecured claims is not adversely affected.

Revesting of Property		All property of the Debtors including any and all potential or actual claims or causes of action of the Debtors (other than the Schedule A Claims) shall be owned by reorganized GMXR, Diamond Blue or Endeavor, or one or more of their affiliates, as applicable, upon the Effective Date of the Plan except as otherwise provided herein.

Conditions & Next Steps:		The effectiveness of any Restructuring shall be subject to customary closing conditions, including, without limitation, satisfaction of all regulatory requirements and the negotiation and execution of definitive documentation, reasonably acceptable to the Steering Committee, the Debtors and, solely to the extent affecting the economic treatment of general unsecured creditors as set forth herein, the Creditors’ Committee, for the transactions described herein.

The Debtors’ release of certain directors and officers that are Protected Persons includes the release of any liability for breach of fiduciary duty or related claims; provided, however that the Litigation Trustee may name any or all of such directors and officers solely as nominal defendants, if the Litigation Trustee determines,


		based upon the written advice of counsel, that it is necessary or required in connection with any post-Effective Date litigation instituted by the Litigation Trustee that seeks recovery under the Debtors’ D&O insurance policies. The Creditors’ Committee, the Litigation Trust, the Litigation Trustee, or any other fiduciary or representative for the Debtors’ general unsecured creditors appointed under a Plan, and each of their respective successors and assigns, shall not bring any causes of action under section 502(d), 544, 545, 547, 548, 549, 550 or 553 of the Bankruptcy Code (collectively, the “Avoidance Actions”) or any other claims or causes of action against any of the Protected Persons; provided further however, that the Creditors’ Committee, prior to the Effective Date, and the Litigation Trustee, upon and after the Effective Date, may take such action as it reasonably deems necessary, based on the advice of counsel, to preserve the proceeds of the Debtors’ D&O insurance policies for the benefit of the estates or the Litigation Trust beneficiaries, as applicable.
