In addition, the Company has granted to the Initial Purchasers an option to purchase up to an additional $20,000,000 in aggregate principal amount of its 5.00% Senior Convertible Notes Due 2013 (the “Optional Securities” and, together with the Initial Securities, the “Securities”). To the extent there are no additional parties listed in Schedule I hereto other than you, the term Representative as used herein shall mean you as the Initial Purchaser and the terms Representative and Initial Purchasers shall mean either the singular or plural as the context requires.

The Securities will be convertible on the terms, and subject to the conditions, set forth in the Indenture (as defined below). As used herein, “Conversion Shares” means the shares of common stock, par value $0.001 per share, of the Company (the “Common Stock”) to be received by the holders of the Securities upon conversion of the Securities pursuant to the terms of the Indenture. The shares of Common Stock also evidence rights (“Rights”) to purchase Series A Junior Participating Preferred Stock of the Company to the extent provided in the Rights Agreement dated May 17, 2005 (the “Rights Agreement”) by and between the Company and ComputerShare Limited, as successor Rights Agent.

The Securities are to be issued pursuant to an indenture (the “Indenture”) dated as of the Closing Date (as defined in Section 4 hereto), between the Company and The Bank of New York Trust Company, N.A., as trustee (the “Trustee”).

The holders of the Securities will be entitled to the benefits of a resale registration rights agreement (the “Registration Rights Agreement”), to be dated as of the Closing Date, between the Company and the Initial Purchasers, pursuant to which the Company will agree to register the Securities and the Conversion Shares for resale on a shelf registration statement pursuant to Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”), subject to the terms and conditions therein specified.

Concurrently with the offering of the Securities, the Company is offering up to an aggregate of 2,140,000 shares of Common Stock (the “Equity Offering”) pursuant to a share lending agreement with an affiliate of the Representative, pursuant to which the Company will lend shares of its common stock to such affiliate (the “Share Lending Agreement”).

The Company understands that the Initial Purchasers propose to make an offering of the Securities as soon as the Representative deems advisable after this Agreement has been executed and delivered.

The sale of the Securities to the Initial Purchasers will be made without registration of the Securities or the Conversion Shares under the Securities Act in reliance upon exemptions from the registration requirements of the Securities Act.

The option hereby granted will expire at 11:59 P.M. (New York City time) on the 30^th day after the date hereof and may be exercised, in whole or in part, from time to time solely for the purpose of covering over-allotments that may be made in connection with the offering and distribution of the Initial Securities upon notice by the Representative to the Company setting forth the number of Optional Securities as to which the several Initial Purchasers are then exercising the option and the time and date of payment and delivery for such Optional Securities.

Delivery of the Securities shall be made through the facilities of The Depository Trust Company unless the Representative shall otherwise instruct.

In addition, in the event that any or all of the Optional Securities are purchased by the Initial Purchasers, payment of the purchase price for, and delivery of certificates for, such Optional Securities shall be made at 10:00 A.M.

1. A certificate, dated such Option Closing Date, to the effect set forth in, and signed by two of the officers specified in, Section 8(d) hereof, except that the references in such certificate to the Closing Date shall be changed to refer to such Option Closing Date.

2. The favorable opinion of Crowe & Dunlevy, PC, counsel for the Company, in form and substance satisfactory to the Representative and dated such Option Closing Date, relating to the Optional Securities to be purchased on such Option Closing Date and otherwise to the same effect as the opinion referred to in Section 8(b) hereof.

3. The favorable opinion of Davis Polk & Wardwell, counsel for the Initial Purchasers, in form and substance satisfactory to the Representative and dated such Option Closing Date, relating to the Optional Securities to be purchased on such Option Closing Date and otherwise to the same effect as the opinion required by Section 8(c) hereof.

4. Letters dated such Option Closing Date in form and substance satisfactory to the Representative from Smith, Carney & Co., independent public accountants, containing statements and information of the type customarily included in accountants’ comfort letters to underwriters with respect to the financial statements and certain financial information contained in the Time of Sale Disclosure Package and the Final Offering Memorandum; provided that the specified date referred to therein for the carrying out of procedures shall be no more than three business days prior to the Option Closing Date.

(k) At the Closing Date and at each Option Closing Date, the Representative and counsel for the Initial Purchasers shall have been furnished with such further information, certificates and documents as the Representative or counsel for the Initial Purchasers may reasonably request.

If any of the conditions specified in this Section 8 shall not have been fulfilled when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be reasonably satisfactory in form and substance to the Representative and counsel for the Initial Purchasers, this Agreement and all obligations of the Initial Purchasers hereunder may be canceled at, or at any time prior to, the Closing Date, or any Option Closing Date, as the case may be, by the Representative. Notice of such cancellation shall be given to the Company in writing or by telephone or facsimile confirmed in writing.

9. Reimbursement of Initial Purchasers’ Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Initial Purchasers set forth in Section 8 hereof is not satisfied, because of any termination pursuant to Section 8(h) hereof or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Initial Purchasers, the Company will reimburse the Initial Purchasers on demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by it in connection with the proposed purchase and sale of the Securities.

10. Indemnification and Contribution.

(a) The Company agrees to indemnify and hold harmless the Initial Purchasers, the directors, officers, employees and agents of the Initial Purchasers and each person who controls any of the Initial Purchasers within the meaning of either the Securities Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Time of Sale Disclosure Package, the Final Offering Memorandum, or any amendment or supplement thereto (including any documents filed under the Exchange Act and deemed to be incorporated by reference into the Final Offering Memorandum), the Pricing Term Sheet, any Supplemental Offering Materials or any other written information used by or on behalf of the Company in connection with the offer or sale of the Securities (or any amendment or supplement to the foregoing), or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Initial Purchasers through the Representative specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(b) The Initial Purchasers agree, severally and not jointly, to indemnify and hold harmless the Company, each of its directors, each of its officers, and each person who controls the Company within the meaning of either the Securities Act or the Exchange Act to the same extent as the foregoing indemnity from the Company to the Initial Purchasers, but only with reference to information relating to the Initial Purchasers furnished to the Company in writing by the Initial Purchasers through the Representative expressly for use in the Time of Sale Disclosure Package, the Final Offering Memorandum, or any amendment or supplement thereto, the Pricing Term Sheet or any Supplemental Offering Materials. This indemnity agreement will be in addition to any liability which any Initial Purchaser may otherwise have. The Company acknowledges that the statements set forth in the last paragraph of the cover page regarding delivery of the Securities and, under the heading “Plan of Distribution”, the paragraph related to stabilization and covering transactions in the Final Offering Memorandum constitute the only information furnished in writing by or on behalf of the Initial Purchasers.

(c) Promptly after receipt by an indemnified party under this Section 10 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 10, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraphs (a) or (b) of this Section 10, as the case may be, unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligations provided in paragraph (a) or (b) above, as the case may be.

The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. It is understood that no Indemnifying Person shall, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons and that all such fees and expenses shall be reimbursed as they are incurred. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of the indemnified party.

(d) In the event that the indemnity provided in paragraph (a), (b) or (c) in this Section 10, as the case may be, is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and each Initial Purchaser, severally and not jointly, agrees to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively “Losses”) to which the Company and any one or more of the Initial Purchasers may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and by the Initial Purchasers, on the other hand, from the offering of the Securities. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Initial Purchasers, severally and not jointly, shall contribute in such proportion as is appropriate to reflect not only such relative benefits received but also the relative fault of the Company, on the one hand, and of the Initial Purchasers, on the other hand, in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by each of them, and benefits received by the Initial Purchasers shall be deemed to be equal to the total discounts and commissions, in each case as set forth on the cover page of the Final Offering Memorandum.

Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company on the one hand or the Initial Purchasers on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Initial Purchasers agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 10, each person who controls an Initial Purchaser within the meaning of either the Securities Act or the Exchange Act and each director, officer, employee and agent of an Initial Purchaser shall have the same rights to contribution as such Initial Purchaser, and each person who controls the Company within the meaning of either the Securities Act or the Exchange Act, each officer of the Company who shall have signed the Final Offering Memorandum and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d). Notwithstanding the provisions of this Section 10, in no event shall the Initial Purchasers be required to contribute any amount in excess of the discount or commission applicable to the Securities purchased by the Initial Purchasers hereunder.

11. Default by One or More of the Initial Purchasers. If any one or more of the several Initial Purchasers shall fail or refuse to purchase Securities that it or they have agreed to purchase hereunder on the Closing Date, and the aggregate number of Securities that such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase does not exceed 10% of the aggregate number of the Securities to be purchased on such date, the other Initial Purchasers shall be obligated, severally, in the proportions that the amount of Securities set forth opposite their respective names on Schedule I bears to the aggregate number of Securities set forth opposite the names of all such non-defaulting Initial Purchasers, or in such other proportions as may be specified by the Initial Purchasers with the consent of the non-defaulting Initial Purchasers, to purchase the Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase on such date. If any one or more of the Initial Purchasers shall fail or refuse to purchase Securities and the aggregate number of Securities with respect to which such default occurs exceeds 10% of the aggregate number of Securities to be purchased on the Closing Date, and arrangements satisfactory to the Initial Purchasers and the Company for the purchase of such Securities are not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other party except that the provisions of Section 5 and Section 7 shall at all times be effective and shall survive such termination, but only as to such non-defaulting Initial Purchasers. In any such case either the Initial Purchasers on the one hand or the Company on the other hand shall have the right to postpone the Closing Date, as the case may be, but in no event for longer than seven days in order that any changes to the Final Offering Memorandum or any other documents or arrangements deemed necessary or desirable may be effected.

12. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the Initial Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Initial Purchaser or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 10 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 9 and 10 hereof shall survive the termination or cancellation of this Agreement.

13. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the Initial Purchasers, will be mailed or delivered to Jefferies & Company, Inc., 520 Madison Avenue, 10th Floor, New York, New York 10022, Attention: General Counsel (Fax: 212 ###-###-####); or, if sent to the Company, will be mailed, delivered or telefaxed to it at GMX Resources Inc., 9400 North Broadway, Suite 600, Oklahoma City, Oklahoma 73114, Attention: Chief Financial Officer, facsimile number (405)  ###-###-####, with a copy (which shall not constitute notice) to: Crowe & Dunlevy PC, 20 North Broadway, Suite 1800, Oklahoma City, Oklahoma 73102, Attention: Michael Stewart, Esq., facsimile number (405)  ###-###-####; or in each case to such other address as the person to be notified may have requested in writing. Any party to this Agreement may change such address for notices by sending to the parties to this Agreement written notice of a new address for such purpose.

14. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors, employees, agents and controlling persons referred to in Section 10 hereof, and no other person will have any right or obligation hereunder.

15. No Advisory or Fiduciary Responsibility. The Company acknowledges and agrees that: (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the public offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and the Initial Purchasers, on the other hand, and the Company is capable of evaluating and understanding and understand and accept the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each transaction contemplated hereby and the process leading to such transaction the Initial Purchasers are and have been acting solely as principals and are not the financial advisors, agents or fiduciaries of the Company, its Subsidiaries, or its affiliates, stockholders, creditors or employees or any other party; (iii) the Initial Purchasers have not assumed and will not assume an advisory, agency or fiduciary responsibility in favor of the Company with respect to any of the transactions contemplated hereby or the process leading thereto (irrespective of whether the Initial Purchasers have advised or are currently advising the Company on other matters) and the Initial Purchasers do not have any obligation to the Company with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement; (iv) the Initial Purchasers and their affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and that the Initial Purchasers have no obligation to disclose any of such interests by virtue of the transactions contemplated hereby; and (v) the Initial Purchasers have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

16. Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.

17. Counterparts. This Agreement may be signed in one or more counterparts, each of which shall constitute an original and all of which together shall constitute one and the same agreement.

Jefferies & Company, Inc.
As Representative of the several Initial Purchasers
(named in Schedule I of the Purchase Agreement)

Jefferies & Company, Inc.
520 Madison Avenue, 10th Floor
New York, New York 10022

Dear Sirs:

The undersigned, a shareholder and an officer and/or director of GMX Resources Inc., an Oklahoma corporation (the “Company”), understands that Jefferies & Company, Inc., as representative of the several Initial Purchasers named in the Purchase Agreement (in such capacity, the "Representative”), propose to enter into a Purchase Agreement (the “Purchase Agreement”) with the Company providing for the offering (the “Offering”), pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”) of Senior Convertible Notes due 2013 of the Company (the “Firm Securities”) and the grant by the Company to the Initial Purchasers of the option to purchase additional Senior Convertible Notes due 2013 (the “Optional Securities”). The Firm Securities, together with the Optional Securities, are collectively referred to as the "Securities”. Capitalized terms used but not defined herein have the meanings given to them in the Purchase Agreement.

In recognition of the benefit that such an offering will confer upon the undersigned as a shareholder and an officer and/or director of the Company, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned hereby irrevocably agrees that, without the prior written consent of Wachovia Capital Markets, LLC, the undersigned will not, and will cause the Company not to, and will not publicly announce any intention to, during the period ending 60 days after the date of the Purchase Agreement, directly or indirectly, (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock; (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise; or (3) file or cause to be filed any registration statement with the SEC relating to the offering of any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock.

Pursuant to the terms of the Purchase Agreement, the restrictions contained in the preceding paragraph shall not apply to (a) the issuance by the Company of shares of Common Stock upon the exercise of an option or warrant or the conversion of a security outstanding on the date hereof of which the Representative has been advised in writing or the granting or exercise of options or stock purchase rights pursuant to the Company’s stock option and stock purchase plans, whenever granted; provided that the underlying shares of Common Stock issued to the undersigned shall continue to be subject to the restrictions contained in the immediately preceding paragraph, except to the extent of any shares sold in order to raise funds sufficient to pay the exercise price and any tax on exercise of options; (b) the issuance by the Company of shares of Common Stock or options to purchase shares of Common Stock to, or the repurchase by the Company of unvested shares of Common Stock upon termination of service from, an employee, director, consultant other service provider, pursuant to the Company’s stock option or stock purchase plans in effect on the date hereof or approved by the Company’s stockholders before the date hereof; provided that the shares of Common Stock or options to purchase shares of Common Stock issued to the Company’s directors and executive officers shall be subject to the restrictions contained herein, except to the extent of any shares sold in order to raise funds sufficient to pay the exercise price and any tax on exercise of options; [and] (c) the filing by the Company of any registration statement with the Commission on Form S-8 relating to the offering of securities pursuant to the terms of a stock option or stock purchase plan of the Company in effect on the date hereof or approved by the stockholders before the date hereof.^*

Notwithstanding the foregoing, if (1) during the last 17 days of the 60-day restricted period the Company issues an earnings release or material news or a material event relating to the Company occurs; or (2) prior to the expiration of the 60-day restricted period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the 60-day period, the restrictions imposed by this agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

In furtherance of the foregoing, the Company and its Transfer Agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Letter Agreement.

It is understood that, if the Company notifies you that it does not intend to proceed with the Offering, if the Purchase Agreement does not become effective, or if the Purchase Agreement (other than the provisions thereof that survive termination) shall terminate or be terminated prior to payment for and delivery of the Securities, the undersigned will be released from his obligations under this Lock-Up Letter Agreement.

*		The letter for Mr. Ken Kenworthy, Sr. shall include the following clause: “and ; (d) the sale of 100,000 shares of Common Stock, which shall be permitted at any time 45 days after the date of the Final Offering Memorandum.”

The undersigned understands that the Company and the Representative will proceed with the Offering in reliance on this Lock-Up Letter Agreement.

Whether or not the Offering actually occurs depends on a number of factors, including market conditions. Any Offering will only be made pursuant to a Purchase Agreement, the terms of which are subject to negotiation between the Company and the Representative.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Letter Agreement and that, upon request, the undersigned will execute any additional documents necessary in connection with the enforcement hereof. Any obligations of the undersigned shall be binding upon the heirs and personal representatives of the undersigned.

Yours very truly,
