After giving effect to the Transactions (including, without limitation, the retirement of existing indebtedness and the related agreements contemplated thereby), no security agreement, financing statement, equivalent security or Lien instrument or continuation statement authorized by the Company or any Guarantor and listing the Company or any Guarantor as debtor covering all or any part of the Collateral shall be on file or of record in any jurisdiction, except in respect of Permitted Liens or such as may have been filed, recorded or made as contemplated by the Transaction Documents.

(kk) The historical financial statements (including the related notes and supporting schedules) included in or incorporated by reference into the Disclosure Package present fairly in all material respects the financial condition, results of operations and cash flows of the entities purported to be shown thereby, at the dates and for the periods indicated, and have been prepared in conformity with accounting principles generally accepted in the United States applied on a consistent basis throughout the periods involved.

(ll) The Company, the Guarantors and their respective subsidiaries have filed all necessary federal, state and material foreign income and material franchise tax returns required to be filed prior to the date hereof (taking into account extensions requested in good faith by the Company and in compliance with applicable tax rules and regulations) and paid all taxes shown as due thereon; all such tax returns are complete and correct in all material respects; all material tax liabilities are adequately provided for on the books of the Company, the Guarantors and their respective subsidiaries; and the Company and the Guarantors have no knowledge of any tax proceeding or action pending or threatened against the Company, the Guarantors or any of their respective subsidiaries that, individually or in the aggregate, might have a Purchase Agreement Material Adverse Effect.

(mm) No labor disturbance by or dispute with the employees of the Company or any of its subsidiaries exists or, to the knowledge of the Company or such subsidiaries, is imminent that would reasonably be expected to have a Purchase Agreement Material Adverse Effect.

(nn) The operations of the Company, the Guarantors and their respective subsidiaries are and have been conducted at all times in compliance with applicable financial recordkeeping and reporting requirements of the Bank Secrecy Act, as amended by Title III of the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001, the Currency and Foreign Transactions Reporting Act of 1970, as amended, and the money laundering statutes of all jurisdictions, the rules and regulations thereunder and any related or similar rules, regulations or guidelines, issued, administered or enforced by any governmental agency (collectively, the “Money Laundering Laws”) and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Company, the Guarantors or any of their respective subsidiaries with respect to the Money Laundering Laws is pending or, to the knowledge of the Company or the Guarantors, threatened.

(oo) None of the Company, the Guarantors or any of their respective subsidiaries nor, to the knowledge of any of the Company or the Guarantors, any director, officer, manager, member, agent, employee or affiliate of any of the Company, the Guarantors or any of their respective subsidiaries is currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control of the U.S. Treasury Department (“OFAC”); and the Company and the Guarantors will not directly or indirectly use the proceeds of the offering of the Notes, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other person or entity, for the purpose of financing the activities of any person currently subject to any U.S. sanctions administered by OFAC.

(pp) Immediately after the consummation of the Transactions, each of the Company and the Guarantors will be Solvent. As used in this paragraph, the term “Solvent” means, with respect to a particular date, that on such date (i) the present fair market value (or present fair saleable value) of the assets of the relevant entity are not less than the total amount required to pay the probable liabilities of such entity on its total existing debts and liabilities (including contingent liabilities) as they become absolute and matured, (ii) the relevant entity is able to realize upon its assets and pay its debts and other liabilities, contingent obligations and commitments as they mature and become due in the normal course of business, (iii) assuming the completion of the transactions contemplated by the Transaction Documents, the relevant entity is not incurring debts or liabilities beyond its ability to pay as such debts and liabilities mature, (iv) the relevant entity is not engaged in any business or transaction, and is not about to engage in any business or transaction, for which its property would constitute unreasonably small capital after giving due consideration to the prevailing practice in the industry in which such entity is engaged, and (v) the relevant entity is not a defendant in any civil action that is reasonably expected to result in a judgment that such entity is or would become unable to satisfy. In computing the amount of such contingent liabilities at any time, it is intended that such liabilities will be computed at the amount that, in the light of all the facts and circumstances existing at such time, represents the amount that can reasonably be expected to become an actual or matured liability.

(qq) To the best knowledge of the Company and the Guarantors, no change in any laws or regulations is pending that could reasonably be expected to be adopted and if adopted, is reasonably expected to have, individually or in the aggregate with all such changes, a Purchase Agreement Material Adverse Effect, except as set forth in or contemplated in the Disclosure Package.

(rr) The Company is subject to Section 13 or 15(d) of the Exchange Act.

(ss) Except as set forth in the Disclosure Package, none of the Company or the Guarantors is a party to any contract, agreement or understanding with any person that would give rise to a valid claim against any of them or the Purchaser for a brokerage commission, finder’s fee or like payment in connection with the Transactions.

(a) Each of the Company and the Guarantors hereby agrees, jointly and severally, to indemnify and hold harmless the Purchaser, its Affiliates, directors, officers and employees and each person, if any, who controls the Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Notes), to which the Purchaser, affiliate, director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any breach by the Company or the Guarantors of any representation or warranty or material failure to comply with any of the covenants and agreements contained in this Agreement, (ii) any untrue statement or alleged untrue statement of a material fact contained (A) in the Disclosure Package or in any amendment or supplement thereto, (B) in any Blue Sky application or other document prepared or executed by the Company or the Guarantors (or based upon any written information furnished by the Company or the Guarantors) specifically for the purpose of qualifying any or all of the Notes under the securities laws of any state or other jurisdiction (any such application, document or information being hereinafter called a “Blue Sky Application”), (iii) the omission or alleged omission to state in the Disclosure Package, or in any amendment or supplement thereto, in any Blue Sky Application, any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (iv) the Transactions (other than those contemplated by this Agreement) and shall reimburse the Purchaser and each such director, officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by the Purchaser, affiliate, director, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred. The foregoing indemnity agreement is in addition to any liability that the Company and the Guarantors may otherwise have to the Purchaser or to any affiliate, director, officer, employee or controlling person of the Purchaser.

(b) Promptly after receipt by an indemnified party under this Section 7 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under this Section 7 except to the extent it has been materially prejudiced

(through the forfeiture of substantive rights or defenses) by such failure and; provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under this Section 7. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 7 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the Purchaser shall have the right to employ counsel to represent jointly the Purchaser and its directors, officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Purchaser against any of the Company or the Guarantors under this Section 7, if (i) the Company, the Guarantors and the Purchaser shall have so mutually agreed; (ii) the Company and the Guarantors have failed within a reasonable time to retain counsel reasonably satisfactory to the Purchaser; (iii) the Purchaser and its respective directors, managers, officers, employees and controlling persons shall have reasonably concluded, based on the advice of counsel, that there may be legal defenses available to them that are different from or in addition to those available to the Company or the Guarantors; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Purchaser or its directors, officers, employees or controlling persons, on the one hand, and the Company or the Guarantors, on the other hand, and representation of both sets of parties by the same counsel would present a conflict due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the Company and the Guarantors. No indemnifying party shall (x) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), 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 a failure to act by or on behalf of any indemnified party, or (y) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment of the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(c) If the indemnification provided for in this Section 7 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 7(a) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, in such proportion as shall be appropriate to reflect the relative fault of the Company and the Guarantors, on the one hand,

and the Purchaser, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company and the Guarantors, or the Purchaser, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Guarantors and the Purchaser agree that it would not be just and equitable if contributions pursuant to this Section 7(c) were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 7 shall be deemed to include, for purposes of this Section 7 any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim.

8. Notices, etc. All statements, requests, notices and agreements hereunder shall be in writing, and:

(a) if to the Purchaser, shall be delivered or sent by hand delivery, mail, telex, overnight courier or facsimile transmission to the address specified on the signature page hereto, with a copy to ▇▇▇▇, Weiss, Rifkind, ▇▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP, ▇▇▇▇ ▇▇▇▇▇▇ ▇▇ ▇▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇, Attention: ▇▇▇▇▇▇▇▇ Wee; and

9. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company or the Guarantors and the Purchaser contained in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall survive the delivery of and payment for the Purchased Notes and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of any of them or any person controlling any of them.

10. Definition of the Terms “Business Day”, “Affiliate”, and “Subsidiary.” For purposes of this Agreement, (a) “business day” means any day on which the New York Stock Exchange, Inc. is open for trading, and (b) “affiliate” and “subsidiary” have the meanings set forth in Rule 405 under the Securities Act.

(b) consents that any such action or proceeding may be brought in such New York Courts and waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such New York Court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same;

(c) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to any party hereto at its address set forth in Section 9 or at such other address of which such party shall have been notified pursuant thereto; and

(d) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the right to ▇▇▇ in any other jurisdiction; and waives, to the maximum extent not prohibited by law, any right it may have to claim or recover in any legal action or proceeding referred to in this Section 13 any special, exemplary, punitive or consequential damages.

13. Waiver of Jury Trial. The Company, the Guarantors and the Purchaser hereby irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

14. Counterparts. This Agreement may be executed in one or more counterparts and, if executed in more than one counterpart, the executed counterparts shall each be deemed to be an original but all such counterparts shall together constitute one and the same instrument.

15. Headings. The headings herein are inserted for convenience of reference only and are not intended to be part of, or to affect the meaning or interpretation of, this Agreement.

16. Delivery of Payment. If the Company has not received payment in full for any of the Purchased Notes purchased pursuant hereto prior to 4:00 p.m., New York City time, on December 19, 2011, upon written request by the Company, the Purchaser shall surrender to the Company for cancellation such Purchased Notes for which payment has not been received.

6. Bankruptcy. There shall be no bankruptcy or insolvency proceedings pending with respect to the Company or any of its subsidiaries.

7. Expenses. All expenses, including legal fees, required to be paid to the Holder under this Agreement shall have been paid in full.

8. Litigation.

9. PATRIOT Act. The Company shall have delivered all documentation and other information reasonably required by regulatory authorities under applicable “know-your-customer” and anti-money laundering rules and regulations, including the PATRIOT Act, in any case, requested in writing by Holder at least three (3) Business Days prior to the closing date for the issuance of the New Notes.

10. Collateral. All Uniform Commercial Code UCC-1 financing statements reasonably necessary or desirable to create and perfect the first priority liens and security interests in respect of the collateral securing the New Notes shall have been delivered for filing, customary short-form security agreements with respect to intellectual property shall have been executed and delivered to the collateral agent for filing with the U.S. Patent and Trademark Office and the U.S. Copyright Office and certificates representing the capital stock and membership interests (to the extent issued and certificated) of the Company and any guarantors shall have been delivered to the collateral agent (or to its designated advisors) under the indenture governing the New Notes; provided that, to the extent the creation of any lien on any collateral or perfection of such lien requires any action on the part of any third party (including, without limitation, delivery of reasonably satisfactory mortgages, title insurance policies, surveys and other customary documentation in connection with real estate collateral) and is not provided on the closing date for the New Notes after the Company’s use of commercially reasonable efforts to do so (other than in respect of the filing of financing statements and the delivery of short-form security agreements and certificates representing capital stock and membership interest, in each case as set forth above), the creation or perfection (as applicable) of such lien

shall not constitute a condition precedent to the issuance of the New Notes on the closing date thereof but such action shall be required to have been taken within a commercially reasonable time after such closing date and in any event within 30 days thereafter, subject to exceptions to perfection requirements to be reasonably agreed.

11. Compliance with Laws. The issuance of the New Notes and other transactions contemplated hereby shall be in compliance in all material respects with all applicable laws and regulations and no order, statute, rule, regulation, executive order, stay, decree, judgment or injunction shall have been proposed, enacted, entered, issued, promulgated, enforced or deemed applicable by any stock exchange, court or any governmental, regulatory or administrative agency or instrumentally, that would or would reasonably be expected to (i) prohibit, prevent, restrict or delay consummation of such transactions or (ii) impose burdensome restrictions on such transactions.

12. Discharge of Existing Debt. After giving effect to the Exchange Offer and the Private Placement, the Company and its subsidiaries shall have (A) no outstanding indebtedness other than (i) up to $318 million of New Notes, (ii) Existing Notes that have not been tendered into the Exchange Offer in an aggregate principal amount not exceeding the amount permitted to remain outstanding after the closing date under the terms of the Definitive Documentation and (iii) other indebtedness as permitted pursuant to the Term Sheet and the other Transaction Documentation; and (B) no liens in respect of borrowed money, other than liens permitted by or expressly provided for under the indenture governing the New Notes or the other Transaction Documentation.

13. Additional Matters. The parties shall, in good faith, work and cooperate together on the corporate, tax and regulatory aspects of the Exchange Offer and the Private Placement so that the resolution of such matters is reasonably satisfactory to the Parties.

Exhibit VIII

SOLVENCY CERTIFICATE

I, ▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, the duly authorized and acting Chief Financial Officer of GMX RESOURCES INC., an Oklahoma corporation (the “Company”), pursuant to the purchase agreements, dated as of December 19, 2011 (each, a “Purchase Agreement” and collectively, the “Purchase Agreements”) by and between the Company and the Purchasers, do hereby certify in the name of and on behalf of the Company and its Subsidiaries, and in my capacity as Chief Financial Officer of the Company, but without any personal liability, as follows (capitalized terms used herein and not otherwise defined herein shall have the meanings ascribed thereto in the Purchase Agreement):

1. On the date hereof and after giving effect to the Transactions:

(a)

the fair value of the assets of the Company and its Subsidiaries, on a consolidated basis, is greater than the total amount of liabilities, including contingent, subordinated, absolute, fixed, matured or unmatured and liquidated or unliquidated liabilities, of the Company and its Subsidiaries, on a consolidated basis;

(b)

the present fair saleable value of the assets of the Company and its Subsidiaries, on a consolidated basis, exceeds (i) the amount that will be required to pay the probable liability of the Company and its Subsidiaries, on a consolidated basis, on the debts of the Company and its Subsidiaries, on a consolidated basis, as such debts become absolute and matured and (ii) the total liabilities of the Company and its Subsidiaries, on a consolidated basis (including, without limitation, subordinated, unmatured, unliquidated and known contingent liabilities);

(c)

the Company and its Subsidiaries, on a consolidated basis, are able to pay their debts and other liabilities, contingent obligations and other commitments as they mature in the normal course of business;

(d)

the Company and its Subsidiaries, on a consolidated basis, are not engaged in business or any transaction, or are about to engage in business or any transaction, for which their property would constitute unreasonably small capital; and

(e)

the Company and its Subsidiaries, on a consolidated basis, are not “insolvent” as such term is defined in Section 101(32) of Title 11 of the United States Code, 11 U.S.C. Section 101, et. seq.

2. In consummating the Transactions, neither the Company nor any of its Subsidiaries intends to hinder, delay or defraud either present or future creditors of the Company or any of its Subsidiaries.

3. In reaching the conclusions set forth in this Certificate, I have made such investigation and inquiries as to the financial condition of the Company and its Subsidiaries as I deem necessary and prudent for the purpose of providing this Certificate, including without limitation:

(a)

the cash and other current assets of the Company and its Subsidiaries, on a consolidated basis; and

(b)

all contingent liabilities of the Company and its Subsidiaries, on a consolidated basis, including, without limitation, claims arising out of pending or threatened litigation against any such entity, and in so doing, have computed the amount of such liabilities as the amount which, in light of all the facts and circumstances existing on the date hereof, represents the amount that can reasonably be expected to become an actual or matured liability.

[REMAINDER OF PAGE INTENTIONALLY LEFT BLANK]

IN WITNESS WHEREOF, I have executed this Certificate as of the date first above written.
