 ARTICLE II 
 TRANSACTIONS 
 Section 2.1 Purchase and Sale. Subject to and in
accordance with the terms hereof, Working Interest Owner agrees to sell and convey to Royalty Owner, and Royalty Owner agrees to purchase from Working Interest Owner, the Production Payment for consideration equal to the Purchase Price, and the
Parties agree to execute and deliver the Closing Documents. Working Interest Owner acknowledges and agrees that the foregoing constitutes payment to Working Interest Owner of reasonably equivalent value for the Production Payment. Royalty Owner will

 Section 2.2 Tax
Reporting. The Parties intend for the Production Payment to be treated for federal income tax purposes (and for the purpose of any similarly calculated state income or franchise taxes, but for no other purposes) as a mortgage loan (and not a

accordingly on all applicable tax returns. In so doing, Working Interest Owner will apply the “noncontingent bond method” of calculating principal and interest as provided in Treasury Regulation section 1.1275-4(b), using a comparable
yield equal to the Projected Yield and calculating a projected payment schedule based on the Scheduled Quantities provided in the Conveyance. If the Scheduled Quantities are ever adjusted as provided in the Production and Marketing Agreement,
Working Interest Owner, with the approval of Royalty Owner, will adjust the projected payment schedule to reflect such changes in the Scheduled Quantities and will appropriately reflect such adjustment to projected payments in determining the amount
of the net adjustment to be taken into account under Treasury Regulation section 1.1275-4(b)(6). 
 ARTICLE III

 REPRESENTATIONS, WARRANTIES AND COVENANTS 
 OF WORKING INTEREST OWNER 
 Section 3.1 Representations and Warranties
of Working Interest Owner. In order to induce Royalty Owner to enter into this Agreement and the Closing Documents and to consummate the transactions described herein, Working Interest Owner hereby represents and warrants to Royalty Owner, and
to each beneficiary or mortgagee under any Mortgage, both as of the date Working Interest Owner executes this Agreement and as of the Closing Date, as follows: 
 (a) Existence and Authorization. Working Interest Owner and Endeavor Pipeline are corporations duly organized, validly existing and in good standing under the Laws of the State of Oklahoma. Each
GMX Company is qualified to do business and is in good standing in the State of Texas. Each GMX Company has the right, power, authority, and qualifications necessary to conduct its business and own its properties (including, as applicable, the
Subject Interests and the Related Assets) in such State, to execute and deliver the Closing Documents to which it is a 

  
 4 








 
party, to perform all of such GMX Company’s obligations under the same, and to convey to Royalty Owner the Production Payment. Working Interest Owner is not a “foreign person”
within the meaning of Sections 1445 and 7701 of the Internal Revenue Code (i.e., Working Interest Owner is not a non-resident alien, foreign corporation, foreign partnership, foreign trust or foreign estate as those terms are defined in the Internal
Revenue Code and any regulations promulgated thereunder). 
 (b) No Conflicts. The execution, delivery and performance by
each GMX Company of the Closing Documents to which it is a party (including Working Interest Owner’s application of the Purchase Price as provided in Section 3.2) are within the corporate or limited liability company power, as applicable,
of such GMX Company, have been authorized by all necessary action on the part of such GMX Company and its shareholders or members and managers, as applicable, and do not and will not (i) violate any provision of such GMX Company’s charter
documents or other governing documents, (ii) violate any provision of Law or any order, writ, judgment, decree or determination currently in effect having applicability to such GMX Company, (iii) result in a breach of or constitute a
default under any Lease, any agreement binding or affecting the Subject Interests (or Working Interest Owner with respect to the Subject Interests), any indenture, bank loan, credit agreement or farmout agreement, program agreement, area of mutual
interest agreement, unit agreement or operating agreement, or any other material agreement or instrument to which such GMX Company is a party or by which such GMX Company or such GMX Company’s properties may be currently bound or affected,
(iv) cause such GMX Company to become obligated to (or obligated to offer to) prepay, redeem or purchase any indebtedness (except the payment described in Section 3.2), or (v) except as set forth in Section 3.1(b) of the
Disclosure Schedule and other than pursuant to the Mortgage, result in or require the creation or imposition of any mortgage, lien, pledge, security interest, charge or other encumbrance upon or of any of the properties or assets of such GMX Company
(including the Subject Interests). No GMX Company is in default under any order, writ, judgment, decree, determination, indenture, agreement or instrument in any manner that now or in the future could materially and adversely affect the ability of
such GMX Company to perform such GMX Company’s obligations under this Agreement or the Closing Documents to which it is a party, and all consents or approvals under such indentures, agreements and instruments necessary to permit the valid
execution, delivery, and performance by such GMX Company of the Closing Documents to which it is a party and the conveyance of the Production Payment to Royalty Owner have been obtained. 

(c) Consents, Preferential Rights and Required Notices. Except as disclosed in Section 3.1(c) of the Disclosure Schedule, all
consents and waivers of preferential purchase or other rights necessary to permit the valid conveyance to Royalty Owner of the Production Payment and execution and delivery of this Agreement and the Closing Documents have been obtained (or deemed
obtained, due to the time for exercising such preferential rights having expired). All advance notifications (if any) to third parties of the transactions contemplated herein and in the Closing Documents necessary to permit the valid conveyance to
Royalty Owner of the Production Payment and execution and delivery of this Agreement and the Closing Documents have been or will be, prior to the Closing Date, timely and properly given. 

  
 5 








 (d) Financial Statements; No Material Adverse Changes. Working Interest Owner has
heretofore delivered to Royalty Owner true, correct and complete copies of Working Interest Owner’s most recent audited annual financial statements (dated as of December 31, 2010) and Working Interest Owner’s most recent unaudited
quarterly financial statements (dated as of September 30, 2011). Such financial statements were prepared in accordance with generally accepted accounting principles, consistently applied, and fairly represent the consolidated financial position
of Working Interest Owner and its subsidiaries as of the dates thereof and their consolidated results of operations and consolidated cash flows for the periods indicated therein (subject, in the case of such quarterly financial statements, to normal
year-end adjustments). Except for matters described in Section 3.1(d) of the Disclosure Schedule, since the date of the most recent audited balance sheet contained in such financial statements, no material adverse change has occurred to the
consolidated financial condition of Working Interest Owner and its subsidiaries or to their consolidated operations, cash flows, properties or prospects. 
 (e) Governmental Approvals. Except for approvals by governmental authorities that are customarily obtained after closing and listed in Section 3.1(e) of the Disclosure Schedule, (i) each
GMX Company has obtained all authorizations, consents, approvals, licenses and exemptions of, and has made all filings and registrations with, any court or governmental department, commission, board, bureau, agency or instrumentality, domestic or
foreign, that are necessary for the valid execution and delivery by such GMX Company of the Closing Documents to which it is a party, and (ii) each GMX Company has obtained all such authorizations, consents, approvals, licenses and exemptions,
and has made all such filings or registrations, that are currently required for the performance of its obligations under this Agreement and the Closing Documents to which it is a party. 

(f) Enforceability. This Agreement has been duly executed and delivered by Working Interest Owner, and as of the Closing Date each
of the Closing Documents will have been duly executed and delivered by each GMX Company. This Agreement constitutes, and as of the Closing Date each of the Closing Documents will constitute, the legal, valid and binding acts and obligations of each
GMX Company that is a party thereto, enforceable in accordance with its terms, subject, however, to bankruptcy, insolvency, reorganization, moratorium and other Laws affecting creditors’ rights generally and to general principles of equity.

 (g) Effective Conveyance of Property Interest. Upon due execution and delivery by Working Interest Owner of the
Conveyance, (i) the Conveyance will constitute the legal, valid and binding conveyance of the Production Payment out of the Subject Interests, and (ii) the Production Payment will constitute an interest in real property owned by Royalty
Owner (and not by Working Interest Owner) and will constitute a “production payment” as defined in Section 101(42A) of the Bankruptcy Code, and referred to in Section 541(b)(4)(B) of the Bankruptcy Code. Neither the Conveyance
nor any Subject Interest constitutes, or will constitute, an executory contract or unexpired lease within the meaning of Section 365 of the United States Bankruptcy Code. 
 (h) Full Disclosure. Taken as a whole, the information, memoranda, exhibits, reports (other than reserve engineering reports), financial statements and other data furnished by or on behalf of
Working Interest Owner to Royalty Owner in connection with the transactions described herein, including the data supplied by or on behalf of Working Interest Owner to the Initial Engineers for use in evaluating the data supplied by Working Interest
Owner to Royalty Owner’s reserve engineers, do not contain any untrue statement of a material fact or omit to state 

  
 6 








 
any material fact that is necessary in order to make the statements therein, in light of the circumstances under which such statements were made, not misleading. To the best of Working Interest
Owner’s knowledge, there is no material fact that has not been disclosed to Royalty Owner that might reasonably be expected to affect the value of the Production Payment or materially and adversely affect the value of the Subject Interests.
Except as listed in Section 3.1(h) of the Disclosure Schedule, there are no reserves in the data supplied by Working Interest Owner to Royalty Owner’s reserve engineers that are attributable to properties and interests other than the
Subject Interests. Except for (i) production from the Subject Wells in the ordinary course of business, (ii) matters listed in Section 3.1(h) of the Disclosure Schedule, and (iii) changes in the general market prices of oil and
natural gas, no material adverse change in the condition of or remaining recoverable proved reserves attributable to the existing Subject Wells or the Subject Interests has occurred since November 30, 2011. The actions of Working Interest Owner
in furnishing information to Royalty Owner in connection with the transactions described herein do not and will not violate any duty owed by Working Interest Owner to any Person to which such information relates or any obligation of Working Interest
Owner under any existing agreement, document, or instrument. 
 (i) Title. Except for liens, security interests and other
rights which are the subject of the Release of Liens and are fully released and discharged thereby, Working Interest Owner owns Good and Defensible Title to each of the Subject Interests, and the GMX Companies own equivalent title to the other
Related Assets, free and clear of any encumbrances, liens or security interests (other than Permitted Encumbrances). 
 (j)
Taxes. All Taxes imposed or assessed with respect to or measured by or charged against or attributable to the Subject Interests, the Subject Hydrocarbons and the Related Assets have been duly paid (including all property and ad valorem taxes
for 2010 and earlier years), except for those not yet due and payable or being contested in good faith by appropriate proceedings. Working Interest Owner has filed all Tax returns required to be filed and such returns comply with applicable Laws.
Except as may be disclosed in Section 3.01(j) of the Disclosure Schedule, no taxing authority is asserting that Working Interest Owner is liable for past due taxes. 
 (k) No Tax Partnership or Other Joint Venture. No Subject Interest is held by, or for any purpose treated as held by, any tax partnership (i.e., any entity, organization or group deemed to be a
partnership within the meaning of section 761 of the Internal Revenue Code, after giving effect to any applicable elections and exclusions) or any other partnership or joint venture. 

(l) Status of Leases and Wells. The Leases are in full force and effect, and Working Interest Owner has complied with all material
terms of the Leases and all governmental orders or directives naming Working Interest Owner or applicable to the Subject Interests. All rents, royalties and other payments due or payable with respect to the Leases have been paid in a timely manner,
and all liabilities of any kind or nature incurred with respect to the Leases have been paid and performed before becoming delinquent. Working Interest Owner is not in default (and has not received any notice of default or claimed default) in any
material respect with respect to any Subject Interest or any Lease or any part thereof. All wells, facilities and equipment which constitute part of the Related Assets are in good repair and working condition


  
 7 








 
(other than wells designated for plugging and abandonment and equipment related thereto) and have been installed and maintained in accordance with good industry standards and all applicable
statutes, rules, regulations, orders, permits or licenses of any governmental authority, agency or court. To the knowledge of Working Interest Owner, no well comprising part of the Subject Interests is or was subject to any penalty on allowables
after the effective date of the Conveyance because of any over-production (or any other judgments, orders or decrees of any court or governmental authority or agency) which would (or did) prevent such well from being entitled to its full legal and
regular allowable (as prescribed by any governmental authority, agency or court) from and after such effective date. If a tract or tracts of land are listed on the Property Exhibit to the Conveyance with respect to a Subject Well, such Subject Well
is located on such tract or tracts of land. If the Subject Interests pertaining to a Subject Well are limited in the Conveyance to specified depths or formations, such Subject Well is producing only from such specified depths or formations, and all
of such specified depths or formations are included within the Subject Interests that pertain to such Subject Well. None of the reserves which comprise Production Payment Hydrocarbons are being produced from any wells other than the Subject Wells
listed on the Property Exhibit, and if the Subject Interests pertaining to a Subject Well are limited on the Property Exhibit to particular depths or formations, all of such reserves pertaining to such Subject Well are located within such depths or
formations. 
 (m) Commitments to Contracts. Except as set forth in Section 3.1(m) of the Disclosure Schedule:

 (i) no third party has any right to purchase any Subject Hydrocarbons (including any call, right of first
refusal or preferential right to purchase) that does not terminate within one month or is not terminable by Working Interest Owner without penalty on notice of one month or less; 

(ii) neither the Subject Interests nor the Hydrocarbons attributable thereto are subject, committed, or dedicated to any
joint operating agreement, unit operating agreement, or area of mutual interest agreement; and 
 (iii) neither
the Subject Interests nor the Hydrocarbons attributable thereto are subject, committed, or dedicated to any Subject Contract that will or could reasonably be expected to (A) reduce the percentage share of the Hydrocarbons produced from or
allocated to any Subject Interest below the Warranted Net Revenue Interest for such Subject Interest, (B) cause Working Interest Owner to be obligated to bear a percentage share of the cost of operation of such Subject Interest that is greater
than the Warranted Working Interest Percentage for such Subject Interest (without a corresponding proportional increase in the associated Net Revenue Interest or a right to reimbursement from a non-paying joint interest owner), or (C) prevent
or interfere with the ownership, exploration, development, operation, maintenance or use of any of the Subject Interests in accordance with prudent industry practices or in accordance with the manner in which such Subject Interest is currently being
owned, explored, developed, operated, maintained or used.

 (n) Gas Balancing; Take or Pay, etc. Except as set forth in Section 3.1(n) of
the Disclosure Schedule, Working Interest Owner is not a party to or bound by, and the Subject Interests and the Hydrocarbons attributable thereto are not encumbered or affected by, any gas balancing, deferred production, gas banking, pipeline,
processing plant or other agreement or arrangement under which one or more third Persons may take any of the production attributable to the Subject Interests (or the products of such production) without full cash payment therefor; and except as set
forth in Section 3.1(n) of the Disclosure Schedule, Working Interest Owner has no obligation in excess of $50,000 due to any “overlift,” “over-produced” or similar status under any such agreement or arrangement. Except as
set forth in Section 3.1(n) of the Disclosure Schedule, neither the Subject Interests nor the Hydrocarbons attributable thereto are subject to any contract, agreement or arrangement (including advance payment agreements, prepayments,
take-or-pay makeup obligations or otherwise) whereby the owner of the Hydrocarbons or any part thereof is not entitled to convey the Hydrocarbons or to market the Hydrocarbons and to obtain the full market price or value of the same. No Subject
Interest is subject on the date hereof to any regulatory refund obligation and, to the best of Working Interest Owner’s knowledge, no facts exist which might cause the same to be imposed. 

(o) Compliance with Laws. Except as set forth in Section 3.1(o) of the Disclosure Schedule, (i) the Subject Interests
have been owned and operated, in all material respects, in accordance with all applicable Laws (including Environmental Laws) of all governmental authorities having or asserting jurisdiction relating to the ownership and operation of the Subject

necessary to determine and has determined that no Hazardous Substance has been disposed of or otherwise released on or to the Subject Lands or produced on the Subject Lands and disposed of or released elsewhere (except for dispositions and releases
done in material compliance with all applicable Laws (including Environmental Laws) and for which no GMX Company otherwise has any material remedial obligations), and the use which the GMX Companies make and intend to make of the Subject Lands will
not result in any such disposal or release; (iii) to the knowledge of each GMX Company, none of the Subject Interests is the subject of any federal, state or local investigation evaluating whether any remedial action is needed to respond to a
release of any Hazardous Substances into the environment or to the improper storage or disposal (including storage or disposal at offsite locations) of any Hazardous Substances; (iv) no GMX Company or, to the knowledge of each GMX Company, any
other Person has filed any notice under any applicable Law indicating that any GMX Company is responsible for the improper release into the environment, or the improper storage or disposal, of any Hazardous Substances or that any Hazardous
Substances have been improperly released, or are improperly stored or disposed of, upon any of the Subject Lands; and (v) no GMX Company or any Affiliate of a GMX Company otherwise has any material contingent liability under any Environmental
Laws or in connection with the release into the environment, or the storage or disposal, of any Hazardous Substances. 
 (p)
No Casualties or Condemnation. Except as disclosed in Section 3.1(p) of the Disclosure Schedule, during the twelve months preceding the Closing Date no Casualty or Condemnation has occurred that, individually or in the aggregate,
adversely affects any material portion of the Related Assets or the use or operation thereof, or adversely affects the ability of any GMX Company to perform its obligations under this Agreement or the Closing Documents to which it is a party. As
used in this subsection, “Casualty or Condemnation” means (i) any fire, blowout, leak, explosion, accident, earthquake, act of public enemy or other casualty (whether above or below ground and regardless of whether
covered by insurance) and (ii) any pending or threatened taking, in condemnation or under the right of eminent domain, of any Related Asset or portion thereof. 

  
 9

Schedule, there are no suits or proceedings pending or, to the knowledge of each GMX Company, threatened against any GMX Company or the Related Assets that involve (i) a dispute or claim concerning title to, operation of, or production from any
of the Subject Interests, (ii) any actual or purported lien, security interest, charge or burden upon any of the Subject Interests or Subject Hydrocarbons, or (iii) any other claim which would affect a transferee of any of the Subject
Interests or would adversely affect the value of the Production Payment. Except as set forth in Section 3.1(q) of the Disclosure Schedule, there are no suits or proceedings pending or, to the knowledge of the GMX Companies, threatened against
any GMX Company or the Related Assets that, if decided adversely to the interest of a GMX Company could materially and adversely affect such GMX Company, any of the Related Assets or the rights of Royalty Owner under the Closing Documents. There are
no bankruptcy, reorganization or similar proceedings pending, being contemplated by or, to the knowledge of each GMX Company, threatened against any GMX Company, and no GMX Company has made a general assignment for the benefit of creditors.

 (r) No Broker’s or Finder’s Fees. Working Interest Owner has not incurred any obligation or liability (or
taken any action) which might impose upon Royalty Owner or Royalty Owner’s lenders or Affiliates any obligation or liability, contingent or otherwise, for broker’s or finder’s fees in respect of any of the matters provided for in this
Agreement or the other Closing Documents. 
 (s) Copies of Permitted Encumbrances and Listed Documents. Working Interest

 (t) Solvency. Upon the execution, delivery and performance by each GMX Company of the Closing Documents to which it is a party (including Working Interest Owner’s application of the Purchase
Price as provided in Section 3.2), each GMX Company is and will be solvent (as such term is used in applicable bankruptcy, liquidation, receivership, or insolvency or similar Laws). Each GMX Company’s capital is adequate for the businesses
in which such GMX Company is engaged and intends to be engaged. No GMX Company has incurred (whether hereby or otherwise), nor does any GMX Company intend to incur or believe that it will incur, debts which will be beyond its ability to pay as such
debts mature. None of the Closing Documents and none of the transactions thereunder constitutes a fraudulent or voidable transfer or conveyance within the scope of Section 548 of the Bankruptcy Code or any other applicable Law pertaining to
fraudulent or voidable transfers or conveyances.

are presently carrying out, or threatening, any strike, slowdown, picketing or work stoppage, and (ii) within the last five years there have not been any strikes, work stoppages, slowdowns, lockouts or other material labor disputes involving
any GMX Company, its employees, or the operation of the Related Assets. 
 (w) Transmitting Utility. Working Interest
Owner is not a “transmitting utility” as defined in Section 9.102(a)(81) of the Uniform Commercial Code presently in effect in the State of Texas. 
 (x) Insurance. The GMX Companies are carrying the insurance described on Schedule 3.7 to the Production and Marketing Agreement and are otherwise in compliance with Section 3.7 of the
Production and Marketing Agreement. 
 (y) No Reliance. Working Interest Owner (i) has made its own independent
decision to enter into this Purchase and Sale Agreement, the other Production Payment Documents, and the transactions contemplated herein and therein and its own independent judgment as to whether such transactions are appropriate or proper for it,
in each case, based upon its own judgment and upon advice from such advisers as it has deemed necessary, and in entering into such transactions is acting for its own account, (ii) is not relying on any communication (written or oral) of Royalty
