 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
pay the Purchase Price to Working Interest Owner at the Closing as provided in Section 6.3. 
 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
“royalty” or other “economic interest” in Hydrocarbons) within the meaning of the Internal Revenue Code and the regulations and judicial authority relating thereto, and the Parties agree to report the Production Payment
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. 

  
 8 

 (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.

 (u) No ERISA Liabilities. No GMX Company has any liabilities or obligations of any
kind with respect to any employee benefit plan that is subject to Title IV of the Employee Retirement Income Security Act of 1974, as amended. 
 (v) Employee Disputes. Except as set forth in Section 3.1(v) of the Disclosure Schedule, (i) neither the workers who operate the Related Assets nor any other employees of any GMX Company
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
Owner, or of Royalty Owner’s Affiliates, as investment advice or as a recommendation to enter into such transactions, it being understood that any information and explanations related to the terms and conditions of such transactions shall not

the terms and conditions and risks of, such transactions and is also capable of assuming, and assumes, such risks, and (iv) acknowledges that Royalty Owner and Royalty Owner’s Affiliates are not, and are not acting as, an adviser to
Working Interest Owner in respect of such transactions with respect to legal, regulatory, accounting, taxation, financial or any other matters in any jurisdiction. 
 Section 3.2 Use of Proceeds. Working Interest Owner warrants and agrees that it will use the Purchase Price to pay for its and Royalty Owner’s out-of-pocket expenses and fees relating to the
sale and purchase of the Production Payment and to the Closing Documents as further set forth herein, to make any payments or repayments required in order to obtain the Release of Liens, to develop its hydrocarbon property base, and for general

(“Royalty Owner” and a “Party”). 
 Working Interest Owner is the owner of the
Subject Interests (defined below), and Working Interest Owner has agreed to convey to Royalty Owner the following described term overriding royalty interest in such Subject Interests. 

Capitalized terms used herein have the meanings given to them in Article II hereof unless otherwise defined herein. 

Accordingly, Working Interest Owner hereby makes the following conveyance and assignment to, and the following agreements for the benefit
of, Royalty Owner: 
 ARTICLE I 
 CONVEYANCE 
 Section 1.1 Conveyance. For and in consideration of One
Thousand Dollars ($1,000.00) and other good and valuable consideration paid by Royalty Owner to Working Interest Owner, the receipt and sufficiency of which are hereby acknowledged, Working Interest Owner hereby GRANTS, BARGAINS, SELLS, CONVEYS,
ASSIGNS, TRANSFERS, SETS OVER AND DELIVERS unto Royalty Owner a term overriding royalty interest in and to the Subject Interests and in and to the Subject Hydrocarbons attributable thereto that is equal to the Production Payment Percentage with
respect to each Subject Interest and the Subject Hydrocarbons attributable thereto (but not to exceed during any Month the Scheduled Quantities plus any Adjustment Quantity of the Subject Hydrocarbons produced and saved that Month), together with
all and singular the rights and appurtenances thereto in anywise belonging (the “Production Payment”). 

TO HAVE AND TO HOLD the Production Payment unto Royalty Owner, its successors and assigns until the Termination Time. 

Section 1.2 Non-Operating, Non-Expense-Bearing Interest. The Production Payment conveyed hereby is a non-operating,
non-expense-bearing limited term overriding royalty interest, free of all cost and expense of production, operations and delivery to the applicable Delivery Points. The Production Payment and the Production Payment Hydrocarbons will be free and
clear of, and in no event will Royalty Owner ever be liable or responsible in any way for payment of, any and all (a) costs, expenses and liabilities associated with acquiring, exploring, developing, drilling, redrilling, maintaining,
producing, operating, reworking, repairing, recompleting, and remediating the Subject Interests, or (b) cash balancing obligations or Delivery Point Charges. All costs and expenses associated with acquiring, exploring, developing, drilling,
redrilling, maintaining, producing, operating, reworking, repairing, recompleting, and remediating the Subject Interests and all cash balancing obligations and Delivery Point Charges will be borne by the Retained Interests and paid by Working
Interest Owner promptly, on or before the dates the same become delinquent. 

 Section 1.3 Royalties; Taxes. The Production Payment will be free and clear of (and
without deduction of) any and all royalties, overriding royalties, other production payments, and other burdens on production and will bear no part of the same; the Retained Interests will be burdened with, and Working Interest Owner will timely
pay, all such royalties, overriding royalties, other production payments, and other burdens on production. Working Interest Owner will defend, indemnify and hold Royalty Owner harmless from and against any loss or claim with respect to any such
royalties and other burdens on production or any claim by the owners or holders of such royalties and other burdens on production. Working Interest Owner will bear and pay all Taxes with respect to the Production Payment and the Production Payment
Hydrocarbons, and the Production Payment Hydrocarbons will be free of Taxes and delivered without deduction for Taxes. 

Section 1.4 Termination. 
 (a) The Production Payment will remain in full force and effect until the Termination Time. At the Termination Time, all rights, titles and interests hereby conveyed to Royalty Owner in the Subject
Interests will automatically terminate and vest in Working Interest Owner and, upon request by Working Interest Owner, Royalty Owner (at Working Interest Owner’s expense) will execute and deliver such instruments (in recordable form) as may be
reasonably necessary to evidence the termination of the Production Payment, provided that, notwithstanding the foregoing or anything herein to the contrary, any obligations which any Person may have to indemnify, reimburse, or compensate Royalty
Owner, or to make payments to Royalty Owner on account of Production Payment Hydrocarbons produced before the Termination Time, or to give reports or take other actions with respect to such Production Payment Hydrocarbons or such payments, will
survive any termination of the Production Payment. 
 (b) No pipeline company or other Person purchasing, taking or processing
Production Payment Hydrocarbons will be required to take notice of or to keep informed concerning termination of the Production Payment until actual receipt of a termination instrument signed by Royalty Owner as contemplated in the preceding
subsection (a). 
 (c) If any individual Subject Interest (or portion thereof, as applicable) should by its terms terminate
before the Termination Time and not be extended, renewed or replaced, then the Production Payment will no longer apply to that particular Subject Interest (or such portion thereof, as applicable), but the Production Payment will remain in full force
and effect and undiminished as to all remaining Subject Interests (and all remaining portions of such Subject Interest, as applicable), as well as to any new lease referred to in the last sentence of the definition of “Lease” in
Section 2.1. No Scheduled Quantity, Adjustment Quantity or Monthly Adjustment Amount will ever be reduced or diminished by reason of the termination of all or any portion of a Subject Interest. 

Section 1.5 Delivery to Royalty Owner. Working Interest Owner will cause the Production Payment Hydrocarbons to be delivered each
Day to Royalty Owner, or to the credit of Royalty Owner, into the facilities of the Delivery Point Recipient at the applicable Delivery 

  
 2 

 
Point, in a condition satisfactory to meet or exceed all specifications and requirements of such Delivery Point Recipient and free of all Delivery Point Charges. Such delivery will be made on a
first priority basis (along with the other Subject Hydrocarbons), to the extent permitted by applicable Law and by any contracts existing on the date hereof, and Working Interest Owner hereby dedicates to the Subject Hydrocarbons all gathering,
transportation, processing, treating and compression plants and equipment (whether owned or possessed by contract right) and all contract rights and other rights useful in making such delivery and agrees that the same will be used to deliver the
Subject Hydrocarbons in such condition prior to being used for other Hydrocarbons belonging to Working Interest Owner or its Affiliates. Although the Production Payment Hydrocarbons are owned by Royalty Owner when and as produced at the wellhead,
Working Interest Owner will be solely responsible for causing delivery thereof to occur at the Delivery Points and for the handling, management and care of the Production Payment Hydrocarbons until such delivery has been completed and solely
responsible for any damage, injury or loss that may occur in connection therewith. To the extent it has the right to do so, Working Interest Owner hereby grants to Royalty Owner and its purchasers and agents easements and rights-of-way over and
across the Leases and all lands subject thereto or pooled, communitized and/or unitized therewith, together with rights of ingress and egress to go on or about such lands and all related production, processing, handling and other facilities, for the
purposes of receiving, accepting and taking Production Payment Hydrocarbons at the applicable Delivery Points and for the further transportation thereof. 
 Section 1.6 Certain Limitations. The Production Payment will be subject to the following provisions: 
 (a) Royalty Owner will look solely to the Production Payment Hydrocarbons for satisfaction and discharge of the Production Payment, and Working Interest Owner will not be personally liable under this
Conveyance for the payment and discharge thereof (although Working Interest Owner will be personally liable for the performance of its representations, warranties, agreements and indemnitees in the Production Payment Documents). 

(b) The Gas produced from the Subject Interests will be allocated first to the Production Payment, and the Oil produced from the Subject
Interests will be allocated first to the Retained Interests, so that the Production Payment Hydrocarbons will consist of Gas to the extent reasonably practicable. 
 (c) Neither the occurrence of an event of force majeure nor any other event or condition reducing or eliminating production or delivery of Subject Hydrocarbons will suspend the calculation and increase of
any Monthly Deficiency or other component of the Monthly Adjustment Amount. 
 Section 1.7 Measurement. Measurement of
the quantities of Subject Hydrocarbons that are Gas will be made by meters located at the applicable Delivery Points. All of such measurements must comply with then current testing methods of the American Society for Testing Materials or the
American Petroleum Institute, and all such Delivery Point meters must measure the volume of Gas (in cubic feet). The MMBtu content of such Gas will be determined by industry standard gas analysis samplings taken at least annually. Measurement of
Subject Hydrocarbons that are Oil will be determined under the applicable agreement with the Delivery 

  
 3 

 
Point Recipient (or under the applicable marketing agreement with any Person purchasing such Oil at the Delivery Point) and, if such agreement does not specify measurement procedures, in
accordance with generally accepted industry practices in effect at the time and place of delivery using then current testing methods of the American Society for Testing Materials or the American Petroleum Institute. All measurements of Gas or Oil
will be subject to the rights of Working Interest Owner and Royalty Owner to audit and confirm such measurements. Working Interest Owner hereby represents, warrants and covenants to Royalty Owner as follows with respect to the Subject Hydrocarbons:
(a) lease level separation of Oil from Gas does and will take place prior to the measuring of the Btu content of such Gas, and (b) production of Gas and of Oil from each Subject Well is and will continue to be measured at a point prior to
any point where Gas or Oil from such Subject Well is commingled with Gas or Oil from any other well or wells that are not Subject Wells. 
 Section 1.8 No Mortgage, Assignment or Pooling by Working Interest Owner. During the term of the Production Payment, (a) Working Interest Owner will not mortgage, pledge or hypothecate the
Subject Interests or create or allow to remain any lien or security interest thereon or on any Hydrocarbons produced therefrom, other than Permitted Encumbrances, and (b) Working Interest Owner will not assign, sell, convey or otherwise
transfer the Subject Interests or any part thereof, unless in each case Royalty Owner expressly consents thereto in writing, the transferee expressly agrees to assume and perform all of Working Interest Owner’s obligations under this Conveyance
and the other documents executed in connection herewith (contingent, in the case of a mortgagee, upon taking possession), and such mortgage, pledge, hypothecation, lien, security interest, assignment, sale, conveyance or other transfer is made and
accepted expressly subject and subordinate to this Conveyance. Any purported mortgage, pledge, hypothecation, lien, security interest, assignment, sale, conveyance or other transfer in violation hereof will be null and void. During the term of the
Production Payment, Working Interest Owner will not – except as may be required by the terms of any existing or new Lease or by the terms of any Law or any order of a court or regulatory authority having jurisdiction, or unless Working Interest
Owner and Royalty Owner have the same or larger Net Revenue Interest in each affected Subject Interest both before and after pooling or unitization–pool, communitize or unitize the Production Payment or the Subject Interests (or amend any
presently existing pooling, communitization or unitization agreement with respect thereto) without the express written consent of Royalty Owner, and any purported pooling, communitization, unitization or amendment in contravention of the preceding
clause will be null and void as to Royalty Owner and will not have the effect of pooling or otherwise affecting the Production Payment. 
 Section 1.9 Title. Working Interest Owner hereby binds itself and its successors and assigns to WARRANT and forever DEFEND all and singular title to the Production Payment and the Production
Payment Hydrocarbons unto Royalty Owner, its successors and assigns, against every Person lawfully claiming or who may claim the same or any part thereof, including any Person claiming under a Permitted Encumbrance. In addition, and without
limitation of the foregoing, Working Interest Owner warrants and represents to Royalty Owner that: 
 (a) each
Lease is a valid and subsisting oil, gas and/or mineral lease, deed or other instrument covering the lands and depths described in such Lease (subject to any limitations as to depth or areal extent set forth in the Property Exhibit with respect to
such Lease); 

  
 4 

 (b) the ownership of Working Interest Owner of the Subject Interests does
and will, with respect to each Lease, unit, formation, or well identified in the Property Exhibit, (i) entitle Working Interest Owner and Royalty Owner collectively to receive and retain a percentage Net Revenue Interest share of the
Hydrocarbons produced from (or, to the extent pooled or unitized, allocated to) such Lease, unit, formation or well equal to (or exceeding) the Warranted Net Revenue Interest Percentage set forth in the Property Exhibit, determined after taking all
Non-Consent Provisions, if any, into account, and (ii) cause Working Interest Owner to be obligated to bear a percentage share of the costs associated with operations on such Lease, unit, formation, or well that is no more than the Warranted
Working Interest Percentage set forth in the Property Exhibit, which share of costs is not subject to increase (except as specifically described in such Exhibit) without either a corresponding proportional increase in the associated Net Revenue
Interest or the right to receive immediate reimbursement for such increased costs from another owner of interests in such Lease, unit, formation or well; 
 (c) such shares of production, as reflected on the Property Exhibit, which Working Interest Owner and Royalty Owner are entitled to receive and retain, and such shares of expenses, as reflected on the
Property Exhibit, which Working Interest Owner is obligated to bear, are not subject to change upon Working Interest Owner’s or any other Person’s achievement of payout or some other measure of recovery of costs incurred with respect to
any of the Subject Interests prior to the Effective Time, except as expressly described in the Property Exhibit; and 
 (d) Working Interests Owner’s title to the Subject Interests, the Subject Hydrocarbons and the facilities, equipment, and all related contractual rights needed for the operation of the Subject
Interests and the production of the Subject Hydrocarbons is free and clear of (i) any encumbrances, liens, mortgages or pledges, other than Permitted Encumbrances and any liens and security interests being released concurrently with the grant
of the Production Payment, (ii) any preferential purchase rights (other than those that have been waived or the time period for exercise of which has expired without exercise) or requirements for consents to assignment (other than those that
have been obtained or waived) that would be applicable to or exercisable as a result of this Conveyance, and (iii) any other defects that would materially and adversely affect or interfere with the operation, use, possession, ownership or value
thereof as currently owned, operated, conducted and used by Working Interest Owner or, if not Working Interest Owner, the current operator of the applicable Lease. 
 This Conveyance is made with full substitution and subrogation of Royalty Owner in and to all covenants, representations and warranties by others heretofore given or made with respect to the Subject
Interests. 
 Section 1.10 No Proportionate Reduction. It is understood and agreed that the Production Payment
Hydrocarbons and the Production Payment Percentages will be determined based on 100% of the full Warranted Net Revenue Interest Percentages of the Hydrocarbons produced from (or, to the extent pooled or unitized, allocated to) the Subject Lands and
will not 

  
 5 

 
be reduced for any reason except to the extent expressly provided in Section 1.11. Among other things, the Production Payment Hydrocarbons and the Production Payment Percentages will not be
reduced due to (a) the undivided interest owned by Working Interest Owner in a Lease being less than the entire interest in such Lease, or (b) the interest in Hydrocarbons or other minerals underlying any portion of the Subject Lands which
is covered by a particular Lease (or group of Leases) being less than the entire interest in the Hydrocarbons and other minerals underlying such portion of the Subject Lands. 
 Section 1.11 Government Regulation. The obligations of Working Interest Owner hereunder will be subject to all applicable Laws. Working Interest Owner will timely make all material filings with all
applicable agencies, boards, officials and commissions having jurisdiction with respect to the Subject Interests, the operation thereof or the Production Payment prior to or at the time any such filing becomes due. Should any Laws, any Leases or any
presently existing provisions in presently existing private contracts (including those limiting the size of overriding royalties and similar interests but excluding any contracts directly entered into by Royalty Owner) be applicable to the Subject
Interests so as to limit the portion of the Hydrocarbons produced from a particular Subject Interest which may be attributable to the Production Payment, the Production Payment will, as to such Subject Interest and for the period of time during
which such Law, Lease or contractual provision is applicable, be limited to the maximum amount of production from such Subject Interest which can be attributed to the Production Payment under such Law, Lease or contractual provision; provided,
however, should such limitation be in effect as to any one or more Subject Interests, then (without prejudice to other rights Royalty Owner may have) the portion of production from (or, to the extent pooled or unitized, allocated to) the other
Subject Interests which would be attributable to the Production Payment in the absence of the provisions of this subsection will be increased to the maximum extent permitted (up to 90%) to cause Royalty Owner to receive, by virtue of ownership of
the Production Payment, the same aggregate amount of Hydrocarbons that Royalty Owner would have received had such Law, Lease or contractual provision not reduced the share of production from such Subject Interest with respect to which the Production
Payment could be paid.

 ARTICLE III 
 MISCELLANEOUS 

Section 3.1 Nature of Production Payment; Intentions of the Parties. This Conveyance is an absolute conveyance of an interest in
real property. The Production Payment constitutes a “production payment” as defined in Section 101(42A) of the Bankruptcy Code and referred to in Section 541(b)(4)(B)(i) of the Bankruptcy Code. The Parties intend for the
Production Payment to at all times 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 “royalty” or other
“economic interest” in Hydrocarbons) within the meaning of the Internal Revenue Code and the regulations and judicial authority relating thereto, and the Parties agree to report the Production Payment accordingly on all applicable tax
returns. Nothing in this Conveyance may be construed to constitute either Party (under state Law or for tax purposes) in partnership with the other Party or to constitute an assignment by Working Interest Owner to Royalty Owner of an interest in any
tax partnership burdening the Subject Interests. The Production Payment does not include any ownership interest in and to any of the fixtures, structures, equipment or other tangible personal property now or hereafter placed on, or used in
connection with, the Subject Interests or any right to conduct operations with any of the foregoing. 
 Section 3.2 Governing
Law. THIS CONVEYANCE IS TO BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF TEXAS. 
 Section 3.3 Successors and Assigns. The covenants, provisions and conditions contained in this Conveyance are agreed and acknowledged to be covenants running with the land and the respective
interests of Working Interest Owner and Royalty Owner and will be binding upon and (subject to the restrictions in Section 1.8) inure to the benefit of Working Interest Owner and Royalty Owner and their respective successors and permitted
assigns. Royalty Owner and its successors and assigns may, and nothing contained in this instrument will 

  
 15 

 
in any way limit or restrict the right of Royalty Owner, or Royalty Owner’s successors and assigns to, sell, convey, assign, mortgage or otherwise transfer the Production Payment or its
rights and obligations under this Conveyance in whole or in part. If at any time Royalty Owner, or Royalty Owner’s successors and assigns, execute a mortgage, pledge or deed of trust covering all or any part of the Production Payment as
security for any obligation, the mortgagee, the pledgee or the trustee therein named or the holder of the obligation secured thereby will be entitled, to the extent such mortgage, pledge or deed of trust so provides, to exercise all of the rights,
remedies, powers and privileges herein conferred upon Royalty Owner and to give or withhold all consents herein required or permitted to be obtained from Royalty Owner. All references herein to either Working Interest Owner or Royalty Owner include
their respective successors and permitted assigns. 
 Section 3.4 Counterpart Execution. This Conveyance is executed in
multiple originals all of which constitute one and the same Conveyance; provided, however, in order to facilitate recording of this Conveyance in the public records of each of the jurisdictions in which the Subject Interests are located (or in each
of the jurisdictions adjacent to any offshore Subject Interests), the exhibits attached to a counterpart recorded in a single jurisdiction may contain only those pages (or portions thereof) which apply to Subject Interests that are located in (or
are adjacent to) such jurisdiction. Complete counterparts of this Conveyance have been retained by each of the Parties, and a complete counterpart of this Conveyance is recorded in Harrison County, Texas. 

Section 3.5 Further Assurances. Working Interest Owner will take all such further actions and will execute, acknowledge and
deliver all such further documents that may reasonably be requested by Royalty Owner to effectuate this Conveyance or to carry out the purposes of this Conveyance. 
 Section 3.6 No Subordination to Permitted Encumbrances. Certain agreements, contracts and other documents are listed in the Property Exhibit and included in the definition of Permitted
Encumbrances. References herein or in the Property Exhibit to Permitted Encumbrances are made solely for the purpose of modifying Working Interest Owner’s warranties and representations as to the Subject Interests, and without regard to whether
or not any Permitted Encumbrance is valid, subsisting, legal or enforceable or affects or is senior to the Production Payment. Such references are not intended to constitute and do not constitute any express or implied recognition or acknowledgment
by any Party as to the validity, legality, enforceability or priority of the same or of any term, provision or condition thereof or the applicability or seniority thereof to the Production Payment and do not revive or ratify the same or create any
rights in any third Person. No provision in this Conveyance may be construed as an agreement or expression of intent by Royalty Owner to acquire the Production Payment subject to any unrecorded Permitted Encumbrance. 

Section 3.7 Partial Invalidity. Except as otherwise expressly stated herein, in the event any term or provision contained in this
Conveyance is for any reason held invalid, illegal or unenforceable to any extent by a court or regulatory agency of competent jurisdiction, such term or provision will otherwise remain effective and be enforced, and all other terms and provisions
hereof will nevertheless remain effective and will be enforced, to the fullest extent permitted by applicable Law.

PARTY HEREBY RATIFIES AND CONFIRMS ITS WAIVERS OF JURY TRIAL AND
