 PIPELINE OPERATING AGREEMENT 
 This Pipeline Operating Agreement (“Agreement”) is dated to be effective as of the Effective Date, by and
between ENDEAVOR PIPELINE INC., an Oklahoma corporation (“EPL” or “Operator”), and ENDEAVOR GATHERING LLC, a Delaware limited liability company
(“Gatherer”). 
 RECITALS 
 WHEREAS, pursuant to the Contribution Agreement dated of even date herewith (the “Contribution Agreement”), GMX Resources
Inc. (“GMX”), the parent entity of EPL, and certain of its Affiliates contributed to Gatherer, and Gatherer accepted and agreed to assume, all assets, rights, and certain obligations of GMX and its Affiliates relating to its and
their natural gas gathering business, including, without limitation, the gas gathering system and related facilities located in Harrison and Panola Counties, Texas, defined herein as “Gatherer’s Systems”; and 
 WHEREAS, pursuant to the Purchase Agreement dated October 16, 2009 (the “Purchase Agreement”), GMX has sold to Kinder
Morgan Endeavor LLC (“KME”), and KME has purchased from GMX, a Membership Interest (as defined in the Purchase Agreement) in Gatherer; and 
 WHEREAS, as part of the transactions described in these recitals (the “Transactions”), GMX, EPL, and Gatherer have entered into a Gas Gathering Agreement dated of even date with this
Agreement, as amended, supplemented, or restated from time to time (the “Gathering Agreement”), pursuant to which Gatherer has agreed to receive, gather, separate, compress, and redeliver to certain transporting pipelines, by means

 WHEREAS, also as part of the Transactions, GMX and Gatherer have agreed that EPL will serve as operator of Gatherer’s Systems, subject
to and in accordance with the terms of this Agreement. 
 NOW, THEREFORE, for and in consideration of the foregoing and
for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Operator and Gatherer agree as follows: 
 1. DEFINITIONS; CONSTRUCTION. In addition to the defined terms in the introductory paragraph and recitals hereof, the capitalized terms and expressions set forth in Part 1 of Schedule 1 shall have the
meanings set forth therein, unless expressly indicated otherwise. Other terms may be defined elsewhere in this Agreement and shall, for purposes hereof, have the meanings so specified, unless expressly indicated otherwise. Rules of contract
construction applicable to this Agreement are set forth in Part 2 of Schedule 1. 

 2. APPOINTMENT OF OPERATOR. EPL is hereby appointed, and EPL hereby agrees to serve, as
Operator of Gatherer’s Systems during the Term, subject to and in accordance with the terms of this Agreement. 
 3. DUTIES,
POWERS, AND LIABILITIES OF OPERATOR. 
 3.1 Duties of Operator. During the Term, EPL, in its capacity as Operator
of Gatherer’s Systems, shall assume full control and responsibility for the efficient and safe performance of Pipeline Operations, subject to and in accordance with the terms of this Agreement. Except as otherwise provided herein, Gatherer
hereby authorizes and empowers Operator to do and perform any and all acts and things necessary, requisite, or proper for the efficient and safe performance of Pipeline Operations on or in connection with Gatherer’s Systems. Without limiting
the generality of the foregoing, the duties of Operator shall include:

 - 3 - 

 (r) to the extent GMX has installed or in the future installs Gas lift
equipment on any well connected to Gatherers’ Systems, Operator shall operate and manage the Gas lift system in a prudent manner (the Parties acknowledge that GMX has equipped the great majority of its Cotton Valley wells with 2  3/8” production tubing and equipped them with Gas
lift valves. The Cotton Valley formation wells produce water (barrels per Mcf) volumes that cause the wells to fill with water and not produce the formation Gas without the Gas lift system. Each of these wells currently requires 350 Mcf/day of Gas
production from the tubing at the wellhead against a line pressure design of 50 psig to maintain minimum lift velocity of Gas through the water. The total Gas lift injection stream required to achieve minimum lift velocity to produce Gas from the
formation is increased over the life of the well as the formation Gas rate declines, until such time as Gas measured at the Receipt Point, as that term is defined in the Gathering Agreement, is the same as Gas measured at the Reinjection Point, as
that term is defined in the Gathering Agreement); and 
 (s) otherwise engage in such planning, perform such
investigations, and formulate such proposals to or on behalf of Gatherer as Operator, in its reasonable judgment, deems necessary to optimize the business of Gatherer with respect to Gatherer’s Systems. 
 3.2 Effectuation with Governmental Entities or Others. At the reasonable request of Operator, Gatherer shall execute (as needed) and
deliver any documents or forms, in the appropriate number of counterparts, which are required by any Governmental Entity, and shall otherwise reasonably cooperate with Operator to effectuate with any Governmental Entity having jurisdiction or other
Person Operator’s status as operator of Gatherer’s Systems during the Term. 
 3.3 Independent Contractor.
Operator shall serve as operator of Gatherer’s Systems under this Agreement as an independent contractor in accordance with the specifications herein set out. Except as expressly otherwise provided in this Agreement, Gatherer shall exercise no
management or control over Operator’s activities hereunder on or in connection with Gatherer’s Systems. Gatherer shall look to Operator for results only and, except as expressly otherwise provided in this Agreement, shall have no right at
any time to direct or supervise Operator or its servants, employees, agents, or representatives as to the manner, means, and method in which Operator conducts Pipeline Operations hereunder. The detailed manner and method of conducting such Pipeline
Operations shall be under the control of Operator. Neither Operator nor anyone employed by Operator shall be deemed to be an employee, agent, servant, or representative of Gatherer. As an independent contractor, neither Operator nor anyone employed
by Operator will be eligible for the benefits provided to regular employees of Gatherer, including health and disability insurance. 
 3.4 No Partnership or Agency. Operator shall not be deemed to be the agent or attorney-in-fact of Gatherer. Operator represents and covenants that it will perform Pipeline Operations and its other obligations under this Agreement as
a legal entity separate and distinct from Gatherer in all material respects. Nothing contained in this Agreement shall be deemed or construed to create a relationship between Gatherer and Operator of partnership, joint venture, agency, or other
relationship creating fiduciary, quasi-fiduciary, or similar duties or obligations inter se, or that would otherwise subject Gatherer and Operator to joint and several or vicarious liability in favor of any other Person. 
  

 - 4 - 

 3.5 Performance Standard. Operator shall carry out its obligations under this
Agreement and shall perform all Pipeline Operations (a) in compliance with all applicable Laws and the terms of all Permits, (b) in accordance with Prudent Industry Practices and the requirements of the applicable Insurance Policies, and
(c) in accordance with this Agreement. 
 3.6 Material Purchase and Disposal. Operator will exercise control over
all requisitions and purchases originated pursuant to this Agreement. Operator will approve all requisitions for materials and will initiate, verify, and conclude all purchase orders for any and all supplies, material, and equipment reasonably
deemed by Operator to be necessary for the safe and efficient performance of Pipeline Operations. Operator may, in its sole discretion, (a) employ its own tools, equipment, supplies, and materials in connection with its operations hereunder and
(b) subcontract the performance of all or a portion of its obligations and responsibilities to third Persons, including Affiliates of Operator; provided, however, that no such subcontract shall relieve Operator of any obligation or liability
hereunder. From time to time during the Term, Operator is authorized to offer for sale to third Persons, for the account of Gatherer, worn out, defective, replaced, or idle materials, tools, facilities or equipment related to Gatherer’s
Systems. All proceeds from such sales shall be distributed to Gatherer promptly after the consummation of the relevant sale. 
 3.7 Permits. During the Term, Operator shall obtain and maintain all Permits it is required to obtain and maintain under all applicable Laws in order to operate Gatherer’s Systems and to perform Pipeline Operations and its other
obligations under this Agreement. During the Term, Gatherer shall obtain and maintain any Permits that Gatherer is required to obtain and maintain in connection with its ownership of Gatherer’s Systems and the performance of its obligations
under this Agreement. Upon request, Operator shall use commercially reasonable efforts to assist Gatherer in obtaining and maintaining any such required Permits of Gatherer. 
 3.8 Bonding. Operator has obtained, and shall maintain during the Term, at Gatherer’s cost and expense, all surety bonds (if
any) required under applicable Laws to be provided by Operator as operator of Gatherer’s Systems. Gatherer shall obtain and maintain all surety bonds required under applicable Law to be provided by Gatherer as the owner of Gatherer’s
Systems. Operator shall use commercially reasonable efforts to assist Gatherer in providing and maintaining all such required surety bonds. 
 3.9 Liabilities of Operator. Except as otherwise provided herein, Operator shall be liable and responsible for all Liabilities of every kind and character caused by, arising out of, or resulting
from Operator’s acts or omissions in its performance of Pipeline Operations and its other obligations hereunder during the Term, except to the extent any such Liability results, in whole or in part, from the gross negligence or willful
misconduct of Gatherer. 
 3.10 Third Person Gathering Agreements. If Gatherer enters into an agreement with a third
Person to receive, gather, and redeliver Gas on behalf of such third Person by means of Gatherer’s Systems (each a “Third Person Gathering Contract”) as contemplated in Article 1.9 of the Gathering Agreement, Operator
shall schedule receipts and deliveries of Gas tendered pursuant to

  

 - 5 - 

 
any such Third Person Gathering Contract into and out of Gatherer’s Systems, and shall otherwise perform and discharge its obligations and responsibilities under this Agreement with respect
to such Gas volumes. 
 3.11 Casualty Event. Operator shall provide to Gatherer a written preliminary estimate of the
cost to repair Gatherer’s Systems as a result of a Casualty Event within sixty (60) days after the occurrence of the Casualty Event. Subject to the other terms of this Agreement, during the Term, Operator shall restore or repair any damage
to Gatherer’s Systems resulting from a Casualty Event. If Gatherer is the loss payee under the relevant Insurance Policies, Gatherer shall, to the extent permitted under such Insurance Policies, direct and cause the insurers under such
Insurance Policies to pay the Insurance Proceeds related to such Casualty Event damage directly to Operator for expenses incurred or to be incurred in repairing or restoring Gatherer’s Systems and removing wreckage or debris related thereto. If
such direction of proceeds is not permitted under the Insurance Policies, Gatherer shall pay to Operator the Insurance Proceeds received from the Insurance Policies, if any, equal to amounts incurred by Operator to restore or repair such Casualty
Event damage or remove wreckage or debris related thereto, as documented by the Claims submitted to and accepted by the insurers. 
 3.12 Intentionally Omitted. 
 3.13 Environmental Matters. Without limiting the generality of
Section 3.9, during the Term, Operator agrees to enter into such agreements as may be necessary or appropriate to document Operator’s on-going and continuing responsibility and obligation for any and all investigatory and remedial
actions required under any Environmental Law or any Permit issued pursuant to an Environmental Law or by any Governmental Entity with respect to or arising out of Gatherer’s Systems or any ownership or operation thereof during the Term,
including actions and activities: (i) to address any alleged violations of any Environmental Law or Permit issued pursuant to an Environmental Law; (ii) to remove, abate, or otherwise address, in compliance with any Environmental Law and
any Permit issued pursuant to an Environmental Law, any Release of Hazardous Materials or Petroleum Materials or other pollution or contamination in respect of Gatherer’s Systems; or (iii) to return any or all of the lands on which
Gatherer’s Systems are located to a condition that meets the requirements of all applicable Laws. Operator shall provide Gatherer prompt written notice of any plans Operator has to conduct such investigatory or remedial actions or of receipt of
any notice from any Governmental Entity requiring Operator to conduct any such investigation or remedial action and will provide Gatherer with quarterly (or more often, if requested by Gatherer) updates in respect of any such activities. All such
investigatory or remedial actions will be performed by Operator in a diligent manner to completion of the activities, consistent with all Environmental Laws and Permits issued pursuant to Environmental Laws. 
 3.14 Metering and Measurement. Matters relating to metering and measurement of Gas received into Gatherer’s Systems shall be
governed by the applicable terms of the Gathering Agreement and the applicable provisions of any Third Person Gathering Contracts. Matters relating to metering and measurement of Gas delivered from Gatherer’s Systems into the Downstream
Pipelines shall be governed by the applicable terms of the Gathering Agreement and the interconnect agreements between GMX (or any of its Affiliates) and the Downstream Pipelines (the “Interconnect Agreements”). Operator agrees to
exercise commercially reasonable efforts to ensure that the provisions of the Interconnect Agreements relating to Gas metering and measurement are properly applied and enforced. 
  

 - 6 - 

 3.15 Hydrocarbon Quality. Matters relating to the quality specifications for Gas
being gathered or exported by means of Gatherer’s Systems (including any modifications of such quality specifications) are governed by the applicable terms of the Gathering Agreement. If Gatherer enters into a Third Person Gathering Contract,
Gatherer shall use commercially reasonable efforts to cause the Gas quality specifications contained in such Third Person Gathering Contract to conform to the quality specifications set forth in the Gathering Agreement. 
 3.16 Imbalances. Accounting for and management of imbalances on Gatherer’s Systems are governed by the terms of the Gathering
Agreement. 
 3.17 Abandonment Activities. During the Term, Operator shall not undertake the abandonment or removal of
Gatherer’s Systems without written authorization from Gatherer. If Gatherer thus authorizes Operator to undertake the abandonment or removal of Gatherer’s Systems, Operator shall perform such abandonment and removal operations in
accordance with the standard of performance set forth in Section 3.5. 
 4. BUDGETS AND FORECASTS OF REVENUE.

 4.1 Operating Budget and Capital Budget. 
 (a) Attached to this Agreement as Exhibits B and C are the Capital Budget (which includes the Expansion Projects described on Exhibit E to the Gathering Agreement) and Operating Budget

forecast of revenues to be generated by Gatherer’s Systems during the next succeeding Gatherer Fiscal Year; and 
 (v) such other information as Gatherer may reasonably request. 
 Notwithstanding the terms of Section 4.1(c), Operator
may, and at the reasonable request of Gatherer shall, propose amendments to any Capital Budget or Operating Budget by providing written notice of the proposed amendment to Gatherer. All Capital Budgets and Operating Budgets shall be itemized by
individual line items in accordance with GAAP or as may be requested by Gatherer. All Capital Budgets and Operating Budgets shall be prepared in contemplation of the work necessary to economically operate Gatherer’s Systems and to permit
Pipeline Operations to be performed hereunder each in accordance with the standard of performance set forth in Section 3.5. 
 (c) Within twenty-five (25) days after the end of each month during the Term, Operator shall prepare and deliver to Gatherer reports showing, for the immediately preceding month, (w) actual
expenditures for Expansion Projects, Well Connects, and Sustaining Projects as compared to budgeted expenditures for such items, (x) actual operating and maintenance expenses as compared to budgeted expenditures for such items, (y) actual
revenues paid to Gatherer in connection with Gatherer’s Systems as compared to budgeted revenues, and (z) any proposals of Operator regarding amendments to the Capital Budget or the Operating Budget or revisions to revenue forecasts for

 (d) Except as provided in Section 4.4 below, Operator shall
not make any expenditure chargeable to Gatherer hereunder during any Gatherer Fiscal Year unless and until there exists a Capital Budget (as to Capital Expenditures) or Operating Budget (as to operating and maintenance expenses) approved by Gatherer
for such Gatherer Fiscal Year. Once Gatherer has approved the Capital Budget and Operating Budget for a Gatherer Fiscal Year, and subject to the terms of Section 4.4, Operator is not authorized to spend amounts during a Gatherer Fiscal
Year in excess of the relevant Capital Budget or Operating Budget without further approval by Gatherer. 
 4.2 Limitation on
Capital Expenditures. All Expansion Projects, Well Connects, and Sustaining Projects shall be authorized by a Capital Budget which shall be prepared by Operator in accordance with Section 4.1 and approved by Gatherer in accordance
with the LLC Agreement. In addition, except as provided hereinafter, all Expansion Projects, Well Connects, and Sustaining Projects shall be submitted to Gatherer for approval prior to Operator making any Capital Expenditures in connection
therewith. Such Capital Expenditures shall be documented by economic studies and a detailed authority for expenditure, which shall contain a full and complete description of the equipment to be purchased or improvements to be made. Operator is not
authorized to spend amounts in excess of the amount thus authorized for each Expansion Project, Well Connect, or Sustaining Project without further approval by Gatherer. Notwithstanding the preceding provisions of this Section 4.2, no
approval by Gatherer (in addition to Gatherer’s approval of

  

 - 8 - 

 
the relevant Capital Budget) shall be required under this Section 4.2 for individual Well Connects or Sustaining Projects if (a) the relevant Well Connect or Sustaining Project
is reflected in a Capital Budget and (b) the estimated expenditure for such Well Connect or Sustaining Project is less than or equal to $100,000.00. 
 4.3 Intentionally Omitted. 
 4.4 Emergency Expenditures.
Notwithstanding the terms of Sections 4.1 or 4.2, in the event of an emergency, Operator may proceed with expenditures reasonably required, in Operator’s sole judgment, to keep Gatherer’s Systems in operation, respond to an
emergency, or to mitigate damages, without the necessity of submitting such proposed expenditures in advance for approval by Gatherer. In such cases, Operator shall be allowed to use any of its or its Affiliates’ operating or administrative
personnel or contractors to take corrective action. Operator shall, as soon as practicable, by telephone notice or otherwise, inform Gatherer of the existence or occurrence of the emergency as defined by Operator. Such notice shall set forth the
nature of the emergency, the corrective action taken or proposed to be taken, and the estimated cost of such corrective action. 
 4.5 Claims and Lawsuits. Operator may settle any single uninsured third Person Claim as to which suit has not been filed arising out of Pipeline Operations conducted by Operator if the expenditure does not exceed $100,000.00 and the
payment is in complete settlement of such Claim. If the amount required for settlement exceeds $100,000.00, or if the claimant has filed suit with respect thereto, Gatherer shall assume and take over the further handling of such Claim or suit,
unless such authority is delegated in writing to Operator. Operator shall reasonably cooperate with Gatherer in the handling of any such Claim or suit. 
 5. PAYMENT OF COSTS AND EXPENSES; REIMBURSEMENT OF CHARGES. 
 5.1 Payment of Costs and Expenses. During the Term, subject to the terms of this Agreement (including, in particular but without limitation, Section 4), Operator shall be responsible for, and shall bear and pay, all costs
and expenses incurred in connection with the ownership of Gatherer’s Systems and Operator’s performance of Pipeline Operations. Gatherer shall be obligated to reimburse Operator for all such costs and expenses in the manner, and subject to
the limitations, set forth in this Section 5.

 5.3 Vendor Disputes. Operator, at Gatherer’s request or at Operator’s
election, shall have the right to contest with any vendor, contractor, subcontractor, supplier, or service provider any invoice presented by such Person for payment, and Operator shall have the right to withhold payment of the disputed invoice, or
the disputed portion of such invoice, as applicable, until such dispute is resolved. 
 5.4 Liens. During the Term,
notwithstanding the terms of Section 5.3, Operator shall take all actions reasonably necessary to avoid the attachment of a lien on Gatherer’s Systems by Operator’s vendors, contractors, subcontractors, suppliers, service
providers, agents, representatives, or invitees, and at its cost, shall immediately remove or cause to be removed any such lien caused by Operator, its vendors, contractors, subcontractors, suppliers, service providers, agents, representatives, or
invitees and shall cause a release of lien or a certificate of discharge to be recorded in the case of any recording of a notice of claim of lien. If any judicial action is commenced against Gatherer’s Systems or Gatherer’s Systems are

such purposes from payments made to Operator. Operator may replace one or more of the Allocated EPL Personnel in its sole discretion, but Operator may not add individuals to the number of Allocated EPL Personnel set forth on Exhibit E
whose salaries and wages are chargeable to Gatherer without Gatherer’s prior approval, which approval shall not be unreasonably withheld, conditioned or delayed. Operator shall provide to Gatherer written notice as necessary identifying any
such replacement or approved additional Allocated EPL Personnel, the percentages of their time allocated to work on or in connection with Gatherer’s Systems (if applicable), and their compensation levels as well as any future adjustments to the
compensation levels of the Allocated EPL Personnel to be charged to Gatherer hereunder. Gatherer’s consent to increases in the compensation levels of the Allocated EPL Personnel charged to Gatherer by Operator hereunder shall not be required

substantially equivalent to the rates then currently being paid by Operator in the usual course of its business to its employees in similar job classifications working in similar geographic areas. Notwithstanding the foregoing, if Operator
terminates the employment of one or more of the Allocated EPL Personnel, or one of the Allocated EPL Personnel resigns his or her employment with Operator, Operator agrees to satisfy and discharge, and to indemnify and hold Gatherer free and
harmless from and against any and all Claims and Liabilities arising out of or related to, all obligations owed to such terminated or resigned employee with respect to final pay and, to the extent such employee is entitled thereto, termination or

materials, equipment, or supplies are moved from Gatherer’s Systems to Operator’s warehouse or other storage point, no charge to Gatherer for transportation shall be made for a distance greater than the distance from the nearest supply
store where like materials, equipment, and supplies are normally available, or the railway receiving point nearest to Gatherer’s System, unless agreed to by the Parties; 
 (e) subject to the terms of Section 5.5(g), actual costs of materials, equipment, and supplies held in inventory or purchased by

shared equally; 
 (g) charges for materials and supplies owned by Operator equal to the then-current fair market value of such
materials and supplies, and charges for use of equipment owned by Operator equal to the then-current average prevailing commercial rate for such equipment in the Area of Interest, based on supporting documentation provided by Operator that is
reasonably satisfactory to Gatherer; provided that in the case of Operator-owned or Operator-leased motor vehicles, Operator shall use rates published by the Petroleum Motor Transport Association or other organization recognized by the Council of
Petroleum Accountant Societies (COPAS) as the official source of such rates; 
 (h) actual costs of contract services,
equipment, and utilities provided by sources other than Operator; 
 (i) all costs and expenses, in excess of Insurance Proceeds

 5.6
Reimbursement by Gatherer. Operator shall deliver to Gatherer, on or before the twenty-fifth (25th) day of each calendar month, a schedule (the “Reimbursement Schedule”) showing the invoices

 6. INSURANCE; INDEMNITY. 
 6.1 Insurance. 

(a) Gatherer. Gatherer, at its cost and expense, and with deductibles for its own account, shall secure and maintain at all times
during the term of this Agreement, with insurance companies authorized to do business in the State of Texas, Insurance Policies with the types of coverage and the policy limits set forth for such policies in Exhibit D. Gatherer shall also be
responsible for all costs and expenses incurred by Operator in connection with providing all surety bonds (if any) required by any Governmental Entity in connection with Gatherer’s Systems or the performance of Pipeline Operations. 

(b) Operator. Operator, at its cost and expense, and with deductibles for its own account, shall secure and maintain at all times
during the Term, with insurance companies authorized to do business in the State of Texas, Insurance Policies with the types of coverage and policy limits set forth for such policies in Exhibit D. 
 (c) Certificates of Insurance. Prior to the start of work under this Agreement, each Party will deliver to the other Party one
(1) or more certificates setting forth proof of insurance coverage as required by this Section 6.1, including the types of coverage and policy limits of the insurance carried. All such commercial Insurance Policies shall be provided
by insurers or reinsurers that have an A. M. Best policyholders rating of AX or a Standard & Poor rating of not less than A, unless a particular Insurance Policy required hereunder is not available from insurers satisfying such criteria, in
which case such Insurance Policy shall be obtained from an insurer selected by the Party obtaining such insurance in its reasonable judgment. 
 (d) Scope of Coverage. Notwithstanding the scope of the Liabilities and indemnities contained in this Agreement, including, without limitation, the provisions of Sections 6.2 and 6.3,
each Party agrees to ensure that the Insurance Policies required under this Section 6.1 will provide full coverage as stipulated, subject only to exclusions and limitations that are standard in the insurance industry with respect to the
type of insurance in question and not exclusions or limitations that result from or are in any way related to the scope of such Liabilities and indemnities. For certainty, the Parties agree that all required Insurance Polices will

  

 - 14 - 

 
specifically provide for coverage for all Claims and Liabilities arising as a result of negligence. No insurer shall be entitled to rely on the scope of the Liabilities and indemnities contained
in this Agreement in order to limit or avoid an obligation to provide coverage for any Claims and Liabilities arising under this Agreement. Neither the insolvency or bankruptcy of any insurer, nor the failure or refusal of any insurer to cover any
Claims and Liabilities arising under this Agreement, shall relieve a Party from any of its obligations, Liabilities, or indemnities under this Agreement. 
 6.2 Indemnities of Operator. Regardless of any investigation made at any time by or on behalf of any Party or any information any Party may have, and regardless of the presence or absence of
insurance carried by Operator, Operator shall indemnify and hold harmless Gatherer and its Indemnity Group from and against any and all Claims and Liabilities caused by, arising out of, resulting from, or relating in any way to, and to pay to
Gatherer or its Indemnity Group any sum that Gatherer or its Indemnity Group pays, or becomes obligated to pay, on account of INJURY TO OR DEATH OF ANY PERSON, PERSONS, OR OTHER LIVING THINGS, OR LOSS OR DESTRUCTION OF OR DAMAGE TO PROPERTY
(INCLUDING LOSS OR DAMAGE RESULTING FROM RELEASES OF HAZARDOUS MATERIALS OR PETROLEUM MATERIALS, POLLUTION, CONTAMINATION, OR OTHER DAMAGE TO THE ENVIRONMENT) RESULTING, IN WHOLE OR IN PART, FROM THE ACTS OR OMISSIONS OF OPERATOR IN THE PERFORMANCE
OF PIPELINE OPERATIONS CONDUCTED ON OR IN CONNECTION WITH GATHERER’S SYSTEMS PURSUANT TO THIS AGREEMENT DURING THE TERM, REGARDLESS OF WHETHER SUCH CLAIM OR LIABILITY RESULTS, IN WHOLE OR IN PART, FROM THE NEGLIGENCE (WHETHER SOLE, JOINT, OR
CONCURRENT, ACTIVE OR PASSIVE) OR STRICT LIABILITY (BUT NOT THE GROSS NEGLIGENCE, WILLFUL MISCONDUCT, OR CRIMINAL OR FRAUDULENT BEHAVIOR) OF GATHERER OR ITS INDEMNITY GROUP. The amount of any Claim for indemnity by Gatherer under this
Section 6.2 based upon the negligence or strict liability of Gatherer shall be reduced by the amount of any insurance reimbursement actually paid to Gatherer with respect to such Claim under policies of insurance provided by Gatherer in
accordance with this Agreement. 
 6.3 Indemnities of Gatherer. Regardless of any investigation made at any time by or on
behalf of any Party or any information any Party may have, and regardless of the presence or absence of insurance carried by Gatherer, Gatherer shall indemnify and hold harmless Operator and its Indemnity Group from and against any and all Claims
and Liabilities caused by, arising out of, resulting from, or relating in any way to, and to pay Operator or its Indemnity Group any sum that Operator or its Indemnity Group pays or becomes obligated to pay, on account of INJURY TO OR DEATH OF
ANY PERSON, PERSONS, OR OTHER LIVING THINGS, OR LOSS OR DESTRUCTION OF OR DAMAGE TO PROPERTY RESULTING FROM THE GROSS NEGLIGENCE, WILLFUL MISCONDUCT, OR CRIMINAL OR FRAUDULENT BEHAVIOR OF GATHERER IN CONNECTION WITH THE PERFORMANCE BY OPERATOR OF
PIPELINE OPERATIONS ON OR IN CONNECTION WITH GATHERER’S SYSTEMS PURSUANT TO THIS AGREEMENT DURING THE TERM.

and expense, access to Gatherer’s Systems from time to time and at any time as shall be requested by Gatherer upon reasonable, advance written notice to carry out such inspections of Gatherer’s Systems as Gatherer shall determine
appropriate. Such access shall be subject to all of Operator’s safety and health rules and procedures, and Operator shall have the right to monitor compliance therewith; and Gatherer shall (and shall cause its representatives) to use all
commercially reasonable best efforts to avoid interference with any of Operator’s operations. 
 7.2 Reporting.
Operator shall furnish the following reports to Gatherer: 
 (a) the “monthly statements” provided for in
Section VIII.1 of Annex I of the Gathering Agreement; 
 (b) the Reimbursement Schedule and related materials provided for

for in Section 4; 
 (d) as soon as reasonably practicable, notice of any of the following occurrences: (i) any
Casualty Event resulting in damage to Gatherer’s Systems or any related equipment or materials, which damage is expected to cost more than $50,000.00 to repair or restore; (ii) any Release of Hazardous Materials or Petroleum Materials or
other pollution, contamination, or other environmental incident requiring any report to any Governmental Entity (including all reports and updates required to be given by Operator to Gatherer in connection with investigative and remedial actions by
Operator pursuant to Section 3.13); (iii) any notice of violation, enforcement, or investigation received from a Governmental Entity; or (iv) the commencement of or any threat to commence any litigation against Operator or
Gatherer in any way relating to Gatherer’s Systems; and 
 (e) such other reports and information as Gatherer may
reasonably request from time to time. 
 7.3 Auditing. Gatherer, on reasonable prior notice to Operator, at
Gatherer’s sole cost and expense, shall have the right, at reasonable times during business hours, to audit the books and records of Operator and its Affiliates to the extent necessary to verify the accuracy of any Reimbursement Schedule,
statement, allocation, measurement, computation, charge, or payment made under or pursuant to this Agreement. The scope of any audit shall be limited to the twenty-four (24) month period immediately prior to the month in which the audit is
requested. However, no audit may include any time period for which a prior audit hereunder was conducted, and no audit may occur more frequently than once annually. All Reimbursement Schedules, statements, allocations, measurements, computations,
charges, or payments made in any period prior to the twenty-four (24) month period immediately prior to the month in which the audit is requested, or made in any twenty-four (24) month period for which the audit is requested but for which
a written claim for adjustments is not made within ninety (90) days after the audit is requested, shall be conclusively deemed

  

 - 16 - 

 
true and correct and shall be final for all purposes. To the extent that the foregoing varies from any applicable statute of limitations, the Parties expressly waive all such other applicable
statutes of limitations. Notwithstanding the foregoing, (a) if GMX is required to materially correct or restate its audited financial statements that are filed with the Securities and Exchange Commission, any other Governmental Entity, or any
party to any of its credit agreements, then Gatherer, to the extent it provides Operator written notice within twenty-four (24) months following such material restatement, may audit the relevant books and records of Operator and its Affiliates
for the period covered by the restated financial statements and all subsequent periods up to and including the date of Gatherer’s written notice, and (b) if any officer of GMX is convicted of or admits having committed fraud, then Gatherer
shall have the right to carry out an audit of the relevant books and records of Operator and its Affiliates without regard to any time limits set forth in this Section 7.3. 
 8. FORCE MAJEURE. Neither Party shall be liable to the other Party for failure to perform any of its obligations, other than obligations to pay money or other financial
obligations under this Agreement, to the extent such performance is hindered, delayed, or prevented by Force Majeure. A Party which is unable, in whole or in part, to carry out its obligations under this Agreement due to Force Majeure shall, as soon
as possible, give written and verbal notice to the other Party describing the circumstances underlying such Force Majeure, but in any event not later than five (5) days after the discovery of such Force Majeure. A Party claiming Force Majeure
shall use commercially reasonable efforts to remove the cause, condition, event or circumstance of such Force Majeure, and shall resume performance of any suspended obligation as soon as reasonably possible after termination of such Force Majeure.
The decision to settle a strike or a labor disturbance is at the sole discretion of the Party claiming Force Majeure. 
 9.
GOVERNING LAW. 
 THIS AGREEMENT HAS BEEN EXECUTED AND DELIVERED, AND SHALL BE CONSTRUED, INTERPRETED AND GOVERNED, PURSUANT TO
AND IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS, WITHOUT REGARD TO ANY CONFLICT OF LAWS PRINCIPLES WHICH, IF APPLIED, MIGHT PERMIT OR REQUIRE THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION. 
 10. DISPUTE RESOLUTION. 
 10.1 Applicability. Any controversy or Claim, whether based on contract, tort, statute or other legal or equitable theory (including but not limited to any Claim of fraud, misrepresentation or
fraudulent inducement or any question of validity or effect of this Agreement including this clause) arising out of or related to this Agreement (including any amendments or extensions) or the breach or termination hereof shall be settled by
arbitration in accordance with the then current CPR Institute Rules for Non-Administered Arbitration of Business Disputes, and this provision. The arbitration shall be governed by the United States Arbitration Act, 9 U.S.C.
§§ 116, to the exclusion of any provision of Law inconsistent therewith or which would produce a different result, and judgment upon the award rendered by the Arbitrator may be entered by any court having jurisdiction. Any dispute to
which this Section 10.1 applies is referred to herein as a “Dispute.” With respect to a particular Dispute, each Person that is a party to such Dispute is referred to herein as a “Disputing Party.” The
provisions of this Section 10 shall be the exclusive method of resolving Disputes. 
  

 - 17 - 

 10.2 Negotiation to Resolve Disputes. If a Dispute arises, the Disputing Parties
shall attempt to resolve such Dispute through the following procedure: 
 (a) first, each of the Disputing Parties shall
promptly meet (whether by phone or in person) in a good faith attempt to resolve the Dispute; 
 (b) second, if the Dispute is
still unresolved after ten (10) Business Days following the commencement of the negotiations described in Section 10.2(a), then the chief executive officer or president of each Disputing Party, on behalf of such Disputing Party,
shall meet (whether by phone or in person) in a good faith attempt to resolve the Dispute; 
 (c) third, if the Dispute is still
unresolved after ten (10) Business Days following the commencement of the negotiations described in Section 10.2(b), then the disputing Parties will submit the Dispute to mediation which shall be administered by the American
Arbitration Association under its Commercial Mediation Rules; and 
 (d) fourth, if the Dispute is still unresolved after twenty
(20) Business Days following the commencement of the mediation described in Section 10.2(c), then any Disputing Party may submit such Dispute to binding arbitration under this Section 10 by written notice to the other
Disputing Parties (an “Arbitration Notice”) delivered within thirty (30) days thereafter. At the same time that the Disputing Member sends an Arbitration Notice to the other Disputing Members, it shall also send an Arbitration
Notice to the regional office of the CPR Institute covering Oklahoma City, Oklahoma (the “CPR Institute”). 
 10.3 Selection of Arbitrator. Any arbitration conducted under this Section 10 shall be heard by a sole, independent arbitrator (the “Arbitrator”) qualified by his or
her education, training and experience in the intrastate natural gas pipeline industry to resolve the disputed matters and shall be selected in accordance with this Section 10.3. Each Disputing Party and each proposed Arbitrator shall
disclose to the other Disputing Parties any business, personal or other relationship or affiliation that may exist between such Disputing Party and such proposed Arbitrator within ten (10) Business Days following delivery of the Arbitration
Notice. The Arbitration Notice shall contain a brief description of the nature of the dispute and the name of an Arbitrator proposed by the Disputing Party. If any other Disputing Party objects for any reason to such proposed Arbitrator, it may, on
or before the tenth (10th) Business Day following
delivery of the Arbitration Notice, notify all of the other Disputing Parties of such objection. All of the Disputing Parties shall attempt to agree upon a mutually acceptable Arbitrator. If they are unable to do so within seven (7) Business
Days following delivery of the notice described in the immediately-preceding sentence, any Disputing Party may request the regional office of the CPR Institute covering Oklahoma City, Oklahoma, to designate the Arbitrator who shall be qualified by
his or her education, training and experience in the intrastate natural gas pipeline industry to resolve the disputed matters. Failing designation by the regional office of the CPR Institute, any Disputing Party may in writing request the judge of
the United States District Court for the Western District of Oklahoma senior in term of service to appoint an Arbitrator qualified by his or her education, training and experience in the intrastate natural gas pipeline industry. If the Arbitrator so
chosen shall die, resign or otherwise fail or becomes unable to serve as Arbitrator, a replacement Arbitrator shall be chosen in accordance with this Section 10.3.

 10.4 Conduct of Arbitration. 
 (a) Any arbitration hearing shall be held in Oklahoma City, Oklahoma. The Arbitrator shall fix a reasonable time and place for the hearing
and shall determine the matters submitted to it pursuant to the provisions of this Agreement in a timely manner; provided, however, that if the Arbitrator shall fail to hold the hearing to determine the issue in dispute within sixty
(60) days after the selection of the Arbitrator, then any Disputing Party shall have the right to require a new Arbitrator to be selected under this Section 10. 
 (b) Except as expressly provided to the contrary in this Agreement, the Arbitrator shall have the power (i) to gather such materials,
information, testimony and evidence as it deems relevant to the dispute before it (and each member will provide such materials, information, testimony and evidence requested by the Arbitrator, except to the extent any information so requested is,
subject to an attorney-client or other privilege); (ii) to grant injunctive relief and enforce specific performance; and (iii) to issue or cause to be issued subpoenas (including subpoenas directed to third Persons) for the attendance of
witnesses and for the production of books, records, documents and other evidence. Subpoenas so issued shall be served, and upon application to the court by a Disputing Party or the Arbitrator, enforced, in the manner provided by Law for the service
and enforcement of subpoenas in a civil action; and (iv) to administer oaths. 
 (c) In advance of the arbitration hearing,
the Disputing Parties may conduct discovery in accordance with the Texas rules. Such discovery may include, but is not limited to, (i) the taking of oral and videotaped depositions and depositions on written questions; (ii) serving
interrogatories, document requests and requests for admission; and (iii) any other form and/or method of discovery provided for under the Texas rules. The Arbitrator shall order the Disputing Parties to promptly exchange copies of all exhibits
and witness lists, and, if requested by a Disputing Party, to produce other relevant documents, to answer up to ten (10) interrogatories (including subparts), to respond to up to ten (10) requests for admissions (which shall be deemed
admitted if not denied), and to produce for deposition and, if requested, at the hearing all witnesses that such Disputing Party has listed and up to ten (10) other Persons within such Disputing Party’s control. Any additional discovery
shall only occur by agreement of the Disputing Parties or as ordered by the Arbitrator upon a finding of good cause. Any objections and/or responses to such discovery shall be due on or before fifteen (15) days after service. The Disputing
Parties shall attempt in good faith to resolve any discovery disputes that may arise. If the Disputing Parties are unable to resolve any such disputes, the Disputing Parties may present their objections to the Arbitrator, who shall resolve the
objections in accordance with the Texas rules. The Arbitrator may, if requested by a Disputing Party, order that a trade secret or other confidential research, development, or commercial information not be revealed or be revealed only in a
designated way. 
 (d) The Disputing Parties may also retain, with the consent of the arbitrator, one (1) or more experts
to assist the Arbitrator in resolving the Dispute. The Disputing Parties shall identify and produce a report from any experts who will give testimony and/or evidence at the arbitration hearing. Any testifying experts identified shall be made
available for deposition in advance of any arbitration hearing.

 (e) The Arbitrator shall render its decision in writing within fifteen (15) days of the
conclusion of the hearing. The Arbitrator shall have jurisdiction and authority to interpret and apply the provisions of this Agreement only insofar as shall be necessary in the determination of the Dispute before it, but it shall not have
jurisdiction or authority to add to or alter in any way the provisions of this Agreement. The Arbitrator’s decision shall govern and shall be final, nonappealable (except to the extent provided in the United States Arbitration Act), and binding
on the Disputing Parties hereto, and its written decision may be entered in any court having appropriate jurisdiction. Pending resolution of any Dispute hereunder, performance by the Disputing Parties shall continue so as to maintain the status quo
prior to delivery of the Arbitration Notice for such Dispute, and service of an Arbitration Notice by any Disputing Party shall not divest a court of competent jurisdiction of the right and power to grant a decree compelling specific performance or
injunctive relief in an action brought by the Disputing Parties. THE ARBITRATOR AND ANY COURT ENFORCING THE AWARD OF THE ARBITRATOR SHALL NOT HAVE THE RIGHT OR AUTHORITY TO AWARD DAMAGES TO A DISPUTING PARTY IN A MANNER INCONSISTENT WITH THE
TERMS OF SECTION 23.  
 (f) The responsibility for paying the costs and expenses of the arbitration, including
compensation to the Arbitrator, shall be allocated among the Disputing Parties in a manner determined by the Arbitrator to be fair and reasonable under the circumstances. Each Disputing Party shall be responsible for the fees and expenses of its
respective counsel, consultants and witnesses, unless the Arbitrator determines that compelling reasons exist for allocating all or a portion of such costs and expenses to one or more other Disputing Parties. 
 11. TERM AND TERMINATION OF THIS AGREEMENT. 
 11.1 Term and Termination. Subject to the other terms and provisions hereof (including Section 11.4), the term of this Agreement shall be a period of time (the “Term”)
commencing on the Effective Date and, unless earlier terminated as provided herein, continuing in force and effect until the expiration or termination of the Gathering Agreement. 
 11.2 Early Termination. Notwithstanding the terms of Section 11.1 to the contrary, this Agreement may be terminated prior
to the expiration of the Term upon the occurrence of any of the following events: 
 (a) by mutual written agreement of the
Parties; 
 (b) by either Party (the “Non-Affected Party”) upon written notice to the other Party (the
“Affected Party”) following the failure by the Affected Party to perform in any material respect any covenant of the Affected Party under this Agreement (other than the obligation to pay money, which is governed by
Section 11.2(c)), and such failure to perform is not the result of a good faith dispute, or excused by Force Majeure, or remedied within sixty (60) days after written notice thereof to the Affected Party; provided, however, that if
Operator is the Affected Party, and Operator’s failure to perform cannot reasonably be cured within such 60-day

  

 - 20 - 

 
period, as long as Operator is diligently and in good faith taking actions to remedy such failure, Operator shall have such period of time as is reasonably necessary to remedy such failure; and
provided, further, that if the period of time to remedy such failure is greater than ninety (90) days, Operator must provide to Gatherer a written work program detailing the actions to be taken by Operator to effect such remedy and the schedule
therefor and shall diligently proceed to take such actions in accordance with such schedule; 
 (c) by Operator if Gatherer
fails to make, when due, any payment required herein, and such failure is not remedied within five (5) Business Days after written notice of such failure to pay from Operator to Gatherer; 
 (d) by the Non-Affected Party if the Affected Party shall: 
 (i) make an assignment or any general arrangement for the benefit of creditors; 
 (ii) file a petition or otherwise commence, authorize, or acquiesce in the commencement of a proceeding or cause under any
bankruptcy or similar law for the protection of creditors, or have such a petition filed against it, and such proceeding remains un-dismissed for thirty (30) Days; 
 (iii) otherwise become bankrupt or insolvent (however evidenced); or 
 (iv) be unable to pay its debts as they fall due. 
 11.3 Wind Up. Upon the expiration or termination of this Agreement, Operator and Gatherer shall enter into a true and final
accounting of all things relating to the business and activities conducted hereunder. Upon the completion of such an accounting, Operator and Gatherer shall each pay to the other such amounts as are necessary to accomplish the purposes of such
accounting, including, without limitation, the payment by Gatherer to Operator of all unpaid amounts owed by Gatherer to Operator pursuant to Section 5. Operator and Gatherer shall give written notice of such expiration or termination to
such third Persons as may be necessary to enable Gatherer independently to resume the operation of and otherwise manage and deal with Gatherer’s Systems, including the Downstream Pipelines, all Persons (other than GMX and EPL) who are shipping
Gas on Gatherer’s Systems, and all applicable Governmental Entities. No later than sixty (60) days after any such expiration or termination, Operator shall turn over to Gatherer all books, files, records, information, and data relating in
any way to Gatherer’s Systems, whether in physical or electronic form, except to the extent that the disclosure of any such books, files, records, information, and data is restricted or prohibited by confidentiality or non-disclosure
restrictions; provided, however, that until such time as such items have been transferred to Gatherer, Operator shall reasonably cooperate with Gatherer and any successor operator of Gatherer’s Systems in furnishing such information from such
items as may be necessary or appropriate to permit the transition of operational matters to Gatherer and/or any such successor operator of Gatherer’s Systems. At any time or from time to time after the expiration or termination of this
Agreement, Operator and Gatherer shall execute and deliver, or cause to be executed and delivered, all such consents, certificates, reports, filings, affidavits, and other documents, and instruments, and shall take or cause to be taken all such
other actions, as either Party may reasonably deem necessary or desirable to effect the expiration or termination of this Agreement in an orderly manner. 
  

 - 21 - 

 11.4 Effect of Termination. Except as provided hereinafter, the expiration or
termination of this Agreement shall not operate to relieve any Party from, or terminate this Agreement with respect to, (a) any Liability or obligation under Sections 5, 6.2, 6.3, 10, 11, 13, 21,
22, 23, 24, and 25, (b) any unfulfilled obligation or undischarged Liability of such Party on the date of such termination, or (c) the consequences of any breach or failure to perform the terms hereof. All such
obligations and Liabilities, and the terms of this Agreement applicable thereto, shall survive such expiration or termination. 
 11.5 Setoff. Each Party reserves to itself all rights, set-offs, counterclaims, and other remedies and defenses which such Party has or may be entitled to arising from or out of this Agreement. Upon the occurrence of an event
described above in Section 11.1 or Section 11.2, all outstanding transactions between the Parties and the obligations to make payment in connection therewith, whether arising under this Agreement, the Gathering Agreement, or
the Services Agreement, may be offset against each other, set off, or recouped therefrom. 
 11.6 Remedies Cumulative.
The right to terminate this Agreement in accordance with the terms of Section 11.2(b) or 11.2(c) shall be in addition to any and all other rights and remedies available to the Party seeking termination in law or in equity for any
breach by the other Party of the other Party’s obligations under this Agreement; all such remedies are cumulative, not exclusive; and such Party may exercise any or all of such remedies in addition to or as an alternative to termination of this
Agreement. 
 12. ENTIRE AGREEMENT. This Agreement, together with the Other Transaction Documents, constitutes the entire
agreement of the Parties, and supersedes (a) all prior oral or written proposals or agreements, (b) all contemporaneous oral proposals or agreements, and (c) all previous negotiations and all other communications or understandings
between the Parties, with respect to the subject matter hereof. 
 13. THIRD PARTY BENEFICIARIES. This Agreement is for the
sole and exclusive benefit of the Parties and KME. No such third party beneficiary shall have any obligation or liability of any kind or character under the terms of this Agreement, however, except for those specifically acknowledged by such third
party beneficiary. Except as otherwise expressly provided herein, nothing herein is intended to benefit any other Person not a Party hereto, and no such Person shall have any legal or equitable right, remedy, or Claim under this Agreement.

 14. NOTICE. All notices, requests, demands, and other communications required or permitted to be given or made hereunder
by a Party shall be in writing and shall be deemed to have been duly given or made if (a) delivered personally, (b) transmitted by first class registered or certified mail, postage prepaid, return receipt requested, (c) delivered by
prepaid overnight courier service requiring acknowledgement of receipt, (d) delivered by electronic mail confirmed by a non-automated response from the recipient, or (e) delivered by confirmed facsimile transmission to the Parties at the

 15. EXHIBITS. All exhibits contained in or attached to this Agreement are integrally related to this Agreement and are hereby made a part of this Agreement for all purposes. To the extent of any ambiguity,
inconsistency, or conflict between the body of this Agreement and any of the exhibits attached to this Agreement, the terms of the body of this Agreement shall prevail. 
 16. NO WAIVER. Neither action taken (including any investigation by or on behalf of any Party) nor inaction pursuant to this Agreement shall be deemed to constitute a waiver of
compliance with any representation, warranty, covenant or agreement contained herein by the Party not committing such action or inaction. A waiver by any Party of a particular right, including breach of any provision of this Agreement, shall not
operate or be construed as a subsequent waiver of that same right or a waiver of any other right. 
 17. ASSIGNMENT; SUCCESSORS AND
ASSIGNS. This Agreement, and the rights created and assigned hereby, may be assigned, in whole but not in part, by either Party; provided, however, that any such assignment shall expressly require the prior written consent of the other
Party, and that each assignee shall assume and agree to discharge the duties and obligations of its assignor under this Agreement. No such consent by either Gatherer or Operator with respect to a transfer by Operator or Gatherer, as applicable, may
be unreasonably withheld, conditioned or delayed; provided that, Gatherer may withhold its consent with respect to a proposed assignee that (a) does not have credit reasonably satisfactory to Gatherer, (b) does not have the expertise,
manpower and means to perform this Agreement according to its terms, or (c) is a competitor of any member of Gatherer. No such assignment shall operate to discharge accrued but unpaid obligations of the assignor under this Agreement.
Notwithstanding the foregoing, either Party shall have the right, without the consent of the other Party, (a) to assign this Agreement, in whole but not in part, to an Affiliate, and (b) to pledge, assign, grant a security interest in, or
otherwise encumber its rights and interests under this Agreement in connection with any financing or other financial arrangement. No such assignment, nor any succession to the interest of either Party, shall be effective and binding until the other
Party is furnished with proper and satisfactory evidence of such assignment or succession. Subject to the preceding provisions of this Section 17, all covenants, stipulations, terms, conditions and provisions of this Agreement shall extend to
and be binding upon the respective successors, assigns, heirs, personal representatives, and representatives in bankruptcy of the Parties. 
  

 - 24 - 

 18. FURTHER ASSURANCES. Each Party agrees to do all acts and things and to execute and
deliver such further documents as may be from time to time reasonably required to carry out the terms and provisions of this Agreement. 
 19. TIME OF THE ESSENCE. Time is of the essence with respect to any and all obligations arising pursuant to this Agreement. 
 20. AMENDMENTS. This Agreement shall not be altered or amended, except by an agreement in writing executed by all Parties. 
 21. INTEGRATED TRANSACTION. Each Party has entered into this Agreement in consideration of (a) the covenants and conditions set
forth herein, the receipt and sufficiency of which are hereby acknowledged, and (b) the execution, delivery, and performance by various parties of the Purchase Agreement, the Services Agreement, the Gathering Agreement, and the other contracts
and agreements among the parties contemplated therein and/or executed in connection therewith (collectively, the “Other Transaction Documents”). The Parties agree that neither Party would have entered into this Agreement without the
Other Transaction Documents; the consideration for entering into this Agreement forms part of the consideration for entering into the Other Transaction Documents; and if, in the event of the bankruptcy of either Party, this Agreement and the Other
Transaction Documents are determined to be executory contracts, this Agreement and the Other Transaction Documents must be rejected or assumed together. 
 22. BANKRUPTCY STAY WAIVER. Each Party agrees that, if it should become a debtor in a bankruptcy proceeding, it expressly waives the provisions of Section 362 of the
Bankruptcy Code as the same pertains to this Agreement. The automatic stay shall not apply to any rights or remedies asserted by the other Party in connection with this Agreement. 
 23. DAMAGES. UNLESS OTHERWISE EXPRESSLY HEREIN PROVIDED, EACH PARTY’S LIABILITY TO THE OTHER PARTY UNDER THIS AGREEMENT SHALL BE LIMITED TO DIRECT ACTUAL DAMAGES ONLY, SUCH DIRECT ACTUAL
DAMAGES SHALL BE THE SOLE AND EXCLUSIVE REMEDY HEREUNDER, AND ALL OTHER REMEDIES OR DAMAGES AT LAW OR IN EQUITY ARE WAIVED. UNLESS EXPRESSLY HEREIN PROVIDED, NEITHER PARTY SHALL BE LIABLE FOR CONSEQUENTIAL, INCIDENTAL, PUNITIVE, EXEMPLARY, OR
INDIRECT DAMAGES, LOST PROFITS OR OTHER BUSINESS INTERRUPTION DAMAGES, WHETHER IN CONTRACT, IN TORT, UNDER ANY INDEMNITY PROVISION, OR OTHERWISE. 
 24. PUBLIC ANNOUNCEMENTS AND DISCLOSURE. Operator shall consult with KME before Operator or any of its Affiliates issues any press release or otherwise makes any public statement or filing with a Governmental Entity
with respect to this Agreement, the Other Transaction Documents, or the transactions contemplated hereby and thereby. Operator and its Affiliates shall not issue any such press release or make any such public statement or filing without the prior
consent of KME, which consent shall not be unreasonably withheld or delayed, except as may be required by Law or applicable rule of any stock exchange. 
  

 - 25 - 

 25. CONFIDENTIALITY. 
 (a) The terms of this Agreement, and the schedules, annexes, and exhibits to this Agreement, shall be kept in strict confidence by the
Parties and shall not be voluntarily disclosed or communicated to any Person not a Party to this Agreement; provided, however, each Party may disclose contents of this Agreement or the schedules, annexes, or exhibits to this Agreement: 

(i) to its parent, subsidiary, and affiliated legal entities and partnerships, and to their respective counsel,
management, financial auditors, bankers, investment bankers, and their respective counsel, to the extent deemed necessary by a Party, provided that such Persons shall be made aware of and agree to maintain the confidential nature of this Agreement;

 (ii) pursuant to any disclosure determined to be necessary under any valid Law or action of any court or
Governmental Entity having jurisdiction over any Party; 
 (iii) to the other owners of interests in the Gas
dedicated to the Gathering Agreement, provided that such owners of interest shall be made aware of and agree to maintain the confidential nature of this Agreement; and 
 (iv) any potential purchasers of the assets and/or equity interests of Operator (or its Affiliate) or Gatherer, provided that
the selling Party shall be fully responsible for maintaining the confidentiality of this Agreement by such potential purchasers. 
 (b) The Parties acknowledge that, from time to time, they may receive information from or regarding any of the other parties or their Affiliates in the nature of trade secrets or secret or proprietary information or information that is
otherwise confidential, the release of which may be damaging to the disclosing Party or its Affiliates, as applicable (collectively, the “Disclosing Party”). Each Party (as applicable, the “Receiving Party”) shall
hold in strict confidence any such information it receives for a period of two (2) years following the receipt of such information and, during such time period, may not disclose such information to any Person, except for disclosures (i) to
comply with any Laws (including applicable stock exchange or quotation system requirements), (ii) to Affiliates, advisers or representatives of the Receiving Party, but only if the recipients of such information have agreed to be bound by the
provisions of this Section 25(b) as an additional Receiving Party, (iii) of information that a Receiving Party also has received from a source independent of the Disclosing Party and that such Receiving Party reasonably believes
such source obtained without breach of any obligation of confidentiality, (iv) of information obtained prior to the execution of this Agreement, provided that this clause (iv) shall not relieve any Receiving Party or any of its
Affiliates from any obligations it may have to any other Party or any of its Affiliates under any existing confidentiality agreement, (v) to lenders, accountants and other representatives of the Receiving Party with a need to know such
information, provided that the Receiving Party shall be responsible for such

  

 - 26 - 

 
representatives’ use and disclosure of any such information, (vi) of public information, or (vii) in connection with any proposed assignment of the rights and obligations under
this Agreement, to advisers or representatives of the Receiving Party, its parent or Persons to which such rights and obligations may be assigned as permitted by this Agreement, but only if the recipients of such information have agreed in writing
to be bound by confidentiality provisions that are no less stringent than those set forth in this Section 25(b). The Parties acknowledge that a breach of the provisions of this Section 25(b) by a Receiving Party may cause
irreparable injury to the Disclosing Party for which monetary damages are inadequate, difficult to compute, or both. Accordingly, the Parties agree that the provisions of this Section 25(b) may be enforced by injunctive action or
specific performance, and the Parties hereby waive any requirement to post bond in connection with any injunctive order or order for specific performance. 
 26. CONSTRUCTION. The Parties hereby stipulate and agree that each of them fully participated and was adequately represented by counsel in the negotiation and preparation of this
Agreement, and the Parties further stipulate and agree that in the event of an ambiguity or other necessity for interpretation to be made of the content of this Agreement, this Agreement shall not be construed in favor of or against any Party as a
consequence of one Party having had a greater role in the preparation of this Agreement, but shall be construed as if the language were mutually drafted by all the Parties with full assistance of counsel. 
 27. SEVERABILITY. If one or more of the provisions contained in this Agreement are for any reason held by a court of competent
jurisdiction to be invalid, illegal, or unenforceable in any respect, the invalidity, illegality, or unenforceability will not affect any other provision of this Agreement, which will be construed as if it had not included the invalid, illegal, or
unenforceable provision. 
 28. CHANGE OF OPERATOR. In the event of the foreclosure by the lenders of GMX, EPL, and/or
their respective Affiliates, pursuant to the terms of credit agreements among such Persons from time to time in effect, of liens or security interests against the membership interest of GMX in Gatherer or all or a portion of the stock of EPL, KME
shall have the right and option, but not the obligation, exercisable by written notice from KME to GMX, EPL, and Gatherer delivered within six (6) months of such foreclosure, to remove EPL as Operator, and to assume the duties, powers,
responsibilities, and obligations of Operator, in each case of Gatherer’s Systems subject to and in accordance with the terms of this Agreement; provided, however, that upon KME’s assumption of the duties, powers, responsibilities, and
obligations of Operator hereunder, KME shall be entitled to reimbursement by Gatherer of all costs and expenses actually and reasonably incurred by KME in connection with the performance of Pipeline Operations hereunder (including salaries, wages,
employee benefits, and costs of insurance of employees of KME or its Affiliates, to the extent of the time spent by such Persons on such Pipeline Operations), notwithstanding any provisions of Section 5.5 to the contrary. The removal of
EPL as Operator of Gatherer’s Systems pursuant to this Section 28 shall not subject KME to any Liability in favor of GMX, EPL, or any of their respective Affiliates. Such removal shall not relieve EPL of any obligation or Liability
of EPL under this Agreement that accrued or arose prior to EPL’s removal as Operator, but EPL shall have no obligation, responsibility, or Liability arising out of or relating to the performance of Pipeline Operations by KME hereunder after
such removal. 
  

 - 27 - 

 29. COUNTERPARTS. This Agreement may be executed in any number of counterparts, and
each such counterpart hereof shall be deemed to be an original instrument, but all of such counterparts shall constitute for all purposes one agreement. At the Parties’ election, this Agreement may be executed by the Parties in different
locations and shall become binding upon both Parties upon the exchange by the Parties of executed signature pages by facsimile. In the event of such a facsimile execution, the Parties shall execute and deliver each to the other a fully executed
original counterpart of this Agreement within thirty (30) days after such facsimile execution hereof; provided, however, that the failure of the Parties to execute such an original counterpart of this Agreement shall not affect or impair the
binding character or enforceability of this Agreement.

 Exhibit 10.3 
 EXECUTION 
 GAS GATHERING AGREEMENT 

This GAS GATHERING AGREEMENT (this “Agreement”) is dated to be effective as of the 1st day of November, 2009 (the
“Effective Date”), by and among Endeavor Gathering LLC, a Delaware limited liability company, hereinafter referred to as “Gatherer”, GMX Resources Inc., an Oklahoma corporation, hereinafter referred to as
“GMX”, the Persons now or hereafter from time to time identified on the signature pages to this Agreement as the “GMX Producer Affiliates” (collectively, with GMX, the “GMX Parties”), and Endeavor
Pipeline Inc., an Oklahoma corporation, hereinafter referred to as “Shipper”. Gatherer, the GMX Parties, and Shipper are sometimes referred to singularly as a “Party” and collectively as the
“Parties”. 
 WITNESSETH: 
 WHEREAS, GMX is a producer and operator of oil and natural gas wells and related facilities in Harrison and Panola Counties, Texas; and

 WHEREAS, Gatherer operates one or more pipeline systems and related facilities in Harrison and Panola Counties, Texas, for
the gathering, separation, compression, and redelivery of Gas described more particularly on Exhibit A, as amended from time to time (“Gatherer’s Systems”); and 
 WHEREAS, Gatherer is not a “gas utility” with the meaning of the Cox Act, TEX. UTIL. CODE ANN. §§121.001, 121.005, and
is not subject to the jurisdiction of the Federal Energy Regulatory Commission under the Natural Gas Act of 1938, 15 U.S.C. §717(b); and 
 WHEREAS, GMX is the sole owner of Shipper, who purchases Gas from GMX and re-sells such Gas at sales points at or downstream from the Delivery Points; and 
 WHEREAS, GMX and Shipper desire Gatherer to receive, gather, separate, compress, and redeliver, by means of Gatherer’s Systems, certain
quantities of Gas owned or Controlled by Shipper and produced from wells located in the vicinity of Gatherer’s Systems in Harrison and Panola Counties, Texas; and 
 WHEREAS, Gatherer is willing to gather, dehydrate (if required pursuant to an approved Expansion Project), separate, compress, and redeliver such quantities of Gas for Shipper in accordance with the terms
and conditions hereinafter set forth. 
 NOW, THEREFORE, in consideration of the premises and mutual covenants hereinafter set
forth, the Parties covenant and agree as follows: 
 ARTICLE I 
 QUANTITY 
 1.1 Dedicated Gas. 
 (a) Subject to the reservations stated in Article 1.2, the GMX Parties hereby commit and dedicate to the performance of this
Agreement, for the Term, all of the Gas that is produced from all present and future wells (except for the wells identified on

 
Exhibit B-3) that are located on the oil and gas leases covering lands in Harrison and Panola Counties, Texas, identified on Exhibit B-1 (the “Leases”) as to
which GMX or a GMX Producer Affiliate serves as operator and in which one or more GMX Parties owned a Working Interest on the Effective Date (the “Dedicated Gas”). The wells from which Dedicated Gas was being produced as of the
Effective Date are also identified on Exhibit B-1. Notwithstanding that the wells identified on Exhibit B-3 are located on the Dedicated Acreage, Gas produced from such wells shall not constitute Dedicated Gas for purposes of this
Agreement. The lands covered by the Leases are shown on the map attached hereto as Exhibit B-2, and such lands are referred to herein as the “Dedicated Acreage.” The geographic area of Harrison and Panola Counties, Texas, is
referred to herein as the “Area of Interest”. 
 (b) If, after the Effective Date, a GMX Party acquires Working
Interests in additional oil and gas leases covering lands in the Area of Interest, all Gas owned or Controlled by the relevant GMX Party that is produced from all wells located on such additional oil and gas leases as to which GMX or a GMX Producer
Affiliate serves as operator shall constitute Dedicated Gas for purposes hereof; such additional oil and gas leases shall be deemed to be Leases for purposes hereof; and all of the lands covered thereby shall be deemed to be a part of the Dedicated
Acreage. Notwithstanding the foregoing, if, after the Effective Date, a GMX Party acquires oil and gas leases covering lands in the Area of Interest that, at the time of the relevant GMX Party’s acquisition thereof, are subject to existing Gas
gathering, transportation, purchase (at the wellhead), or similar agreements with third Persons, such oil and gas leases and lands shall not be deemed to constitute, respectively, Leases or a part of the Dedicated Acreage for purposes hereof until
such existing agreements expire or are terminated or released pursuant to the terms of any such agreements. The relevant GMX Parties shall use reasonable commercial efforts to obtain or cause the release or termination of any such existing agreement
at the earliest possible date; provided, however, if any such existing Gas gathering, transportation, wellhead purchase, or similar agreement provides for gathering or other fees for the services provided thereunder to similar delivery points for
Gas that are, in the aggregate, less than the fees payable pursuant to Article 3, or provides for more favorable delivery points for Gas, the GMX Parties shall not be obligated to use reasonable commercial efforts to obtain or cause the
release or termination of the relevant existing agreement, and the GMX Parties may exercise any option to renew or otherwise negotiate to extend any such existing agreement, unless in each case Gatherer elects to provide the services contemplated in
this Agreement based on the fee structure contained in such existing gathering, transportation, wellhead purchase, or similar agreement. 
 (c) If a GMX Party is not the operator of a well located in the Area of Interest, but is nonetheless able to obtain the agreement of all of the owners of Gas produced from such well to commit and dedicate
such Gas production to this Agreement, then upon delivery to Gatherer of written evidence of such agreement, all Gas thus owned or Controlled by the relevant GMX Party that is produced from such non-GMX Party-operated well shall constitute Dedicated
Gas for purposes hereof; the oil and gas lease(s) on which such well is located shall be deemed to be Leases for purposes hereof; and the lands covered thereby shall become part of the Dedicated Acreage. 
  

 - 2 - 

 (d) From time to time as GMX and Gatherer deem appropriate, the Parties shall amend
Exhibit B to reflect the periodic changes to the Leases, producing wells, and Dedicated Acreage contemplated in this Article 1.1. 
 (e) Consistent with the preceding provisions of this Article 1.1, the GMX Parties agree to sell to Shipper, pursuant to current or future Gas sale and purchase agreements between such Parties,
all of the Dedicated Gas; and Shipper hereby commits and dedicates to the performance of this Agreement, for the Term, all Dedicated Gas sold by any of the GMX Parties to Shipper pursuant to such current and future Gas sale and purchase agreements.

 (f) If, at any time during the Term, an Affiliate of GMX that is not a signatory to this Agreement as a GMX Producer
Affiliate acquires a Working Interest in an oil and gas lease covering lands in the Area of Interest that, if acquired by a GMX Party, would constitute a Lease for purposes hereof, GMX shall cause such Affiliate to agree in writing to assume and to
agree to pay, perform, and discharge all of the duties, obligations, responsibilities, and Liabilities of a GMX Party under, and otherwise to be bound by the terms of, this Agreement. Thereafter, such Affiliate of GMX shall be deemed to be a GMX
Producer Affiliate for all purposes hereunder, and any such oil and gas lease or Working Interest acquired by such Affiliate of GMX shall be deemed to be a Lease subject to and in accordance with the terms hereof. 
 1.2 Shipper’s Reservation. Notwithstanding the terms of Article 1.1, the GMX Parties and Shipper expressly except and
reserve to themselves, severally according to their respective ownership interests and not jointly, the following rights with respect to the Dedicated Gas: (a) prior to the delivery thereof to Gatherer at the Receipt Points, the right to
recover from the Dedicated Gas condensate and other liquefiable hydrocarbons that collect as the result of condensation in pipelines or are recoverable by the utilization of separation facilities; (b) the right to process (including
fractionation) the Dedicated Gas for the removal of liquid hydrocarbons downstream of the Delivery Points; (c) the right to receive all liquid hydrocarbons that are removed or that naturally collect from the Dedicated Gas on Gatherer’s
Systems downstream of the Receipt Points, whether by processing and/or fractionation, or from condensation in any pipelines; (d) the right to use that portion of the Dedicated Gas that the GMX Parties deem necessary to develop and operate the
Leases, including, without limitation, the use of Dedicated Gas for Gas lift; (e) the right to use that portion of the Dedicated Gas required to fulfill the obligations of the GMX Parties to lessors and other royalty owners who take in kind
their royalty shares of Gas produced from the Leases; (f) the right to pool, unitize, or communitize the Leases, or any portion thereof, with other lands or leases and, in the event of such a pooling, unitization, or communitization, this
Agreement will cover, as Dedicated Gas, the pooled, unitized, or communitized portion of the Gas produced from wells operated by a GMX Party located on the pool or unit formed that is owned or Controlled by a GMX Party; and (g) subject to
GMX’s obligations under Section 6.4 of the Purchase Agreement, the right to operate the Leases as the GMX Parties, in their sole judgment and as a reasonable prudent operator, deem advisable, including, without limitation, the rights, but
not the obligations, to (i) drill new wells; (ii) repair and rework old wells; (iii) curtail, shut-in, vent, or flare Gas production subject to the compliance by the GMX Parties with applicable Laws; (iv) renew or extend, in

 (d) Notwithstanding the preceding provisions of this Article 1.3, except for the Expansion Projects listed on Exhibit E which
have been pre-approved by the Parties, Gatherer shall have the right, but shall not be required, to fund any Expansion Project. If, during any Gatherer Fiscal Year during the Term, Shipper or the GMX Parties desire Gatherer to perform one or more
Expansion

  

 - 4 - 

 
Projects in addition to those described on Exhibit E, such incremental capital investment shall either be funded by Gatherer based on modified commercial terms for this Agreement agreed
upon by the Parties (including a modified schedule of fees and charges), or in the absence of such an agreement by the Parties, by Shipper or the GMX Parties. If Shipper or the GMX Parties elect to fund any such Expansion Project: (i) Gatherer
shall be responsible for performing and conducting the relevant Expansion Project; (ii) all additional pipelines and other facilities designed, fabricated, laid, constructed, and installed pursuant to such Expansion Project shall be owned by
Shipper or the GMX Parties upon payment to Gatherer pursuant to clause (iii) below; (iii) Shipper or the GMX Parties shall pay to Gatherer the full estimated cost of the relevant Expansion Project within five (5) Business Days
after receipt of Gatherer’s invoice therefor, together with available information and data supporting such estimate; (iv) as soon as reasonably practicable after the in-service date for such Expansion Project, Gatherer will provide to
Shipper or the GMX Parties written notice, accompanied by copies of invoices and other supporting information, setting forth the actual costs incurred in connection with such Expansion Project; (v) Shipper or the GMX Parties shall pay, or
reimburse Gatherer if Gatherer has paid, all such actual costs in excess of the estimated costs previously paid by Shipper or the GMX Parties pursuant to clause (iii) above, or Gatherer shall reimburse Shipper or the GMX Parties for any
excess of the estimated costs previously paid by Shipper or the GMX Parties pursuant to clause (iii) above over such actual costs by netting any such amounts owed to Shipper or the GMX Parties against amounts owed by Shipper or the GMX
Parties to Gatherer under other provisions of this Agreement; and (vi) Gatherer shall be entitled to charge Shipper or the GMX Parties an amount agreed upon by Shipper, GMX, and Gatherer representing the costs to Gatherer to operate and
maintain the additional pipelines and other facilities designed, fabricated, laid, constructed, and installed pursuant to such Expansion Project in conjunction with Gatherer’s Systems (the “Expansion Project Operating
Charges”). 
 1.4 Shipper’s Obligation. Subject to the terms of this Agreement, each Day during the Term,
Shipper shall make available to Gatherer, at the Receipt Points, one hundred percent (100%) of the Dedicated Gas produced and available to Shipper on such Day. 
 1.5 Gatherer’s Obligation. Subject to the terms of this Agreement, each Day during the Term, Gatherer shall, on a Firm basis, (a) subject to available capacity at the Receipt Points,
receive from Shipper at the Receipt Points all Dedicated Gas made available by Shipper at the Receipt Points pursuant to Article 1.4, and (b) gather, compress, heat, separate (or operate separators), and, subject to available capacity at
the Delivery Points and affirmation by the receiving operator at the Delivery Points, deliver to or for the account of Shipper, an Equivalent Quantity at the Delivery Points and the Reinjection Points. 
 1.6 Firm Service. The receipt, gathering, and delivery of Gas hereunder shall be on a “Firm” basis, which means that
Shipper shall deliver such Gas to Gatherer, and Gatherer shall receive at the Receipt Points and deliver an Equivalent Quantity to the Reinjection Points or Delivery Points without interruption, suspension, or curtailment, at the fees set out
herein. Notwithstanding the foregoing to the contrary, if either Party interrupts, suspends, or curtails the receipt, gathering, or delivery of Gas hereunder pursuant to applicable Laws or the orders of any court or other tribunal having
jurisdiction, or due to conditions of Force Majeure, or upon the request of any Governmental Entity, or as may otherwise be permitted by the terms of this Agreement, then the interrupting Party shall incur no Liability of any kind or character to
the other Party as a result of or with respect to such interruption, suspension, or curtailment. 
  

 - 5 - 

 1.7 Volume Shortfall Payments. 
 (a) If the Actual Gathered Volumes for a Contract Quarter during the Initial Term are less than the Benchmark Volumes for such Contract
Quarter, Shipper shall pay to Gatherer an amount (the “Volume Shortfall Payment”) equal to the product obtained by multiplying (i) the positive difference, if any, obtained by subtracting the Actual
Gathered Volumes for such Contract Quarter from the Benchmark Volumes for such Contract Quarter, by (ii) the Gathering Rate in effect for such Contract Quarter; provided, however, that Shipper shall have no further obligation to
make Volume Shortfall Payments pursuant to this Article 1.7 from and after the first Day of the month following the month in which the total cumulative quantities of Dedicated Gas delivered by Shipper to Gatherer at the Receipt Points, less
the total cumulative quantities of Dedicated Gas delivered by Gatherer to Shipper at the Reinjection Points, equals the Target Quantity. 
 (b) For purposes of this Agreement, the term “Benchmark Volumes” means, for a Contract Quarter during the Initial Term, the product obtained by multiplying (i) the
“Volume for Shortfall Calculation”, in MMBtu per Day, set forth on Exhibit D for the Contract Year in which the relevant Contract Quarter falls, by (ii) the number of Days in such Contract Quarter. 
 (c) For purposes of this Agreement, the term “Actual Gathered Volumes” means, for a Contract Quarter during the Initial
Term, the sum of: (i) all volumes of Dedicated Gas, measured at the Receipt Points, gathered on Gatherer’s Systems during the relevant Contract Quarter, regardless of whether a GMX Party is the operator of the wells from
which such Gas is produced, less all volumes of Gas delivered at the Reinjection Points, plus (ii) the applicable Adjustment Percentage of the volumes of Gas produced from wells located on the Dedicated Acreage in which a GMX Party owns
a Working Interest that are gathered on Gatherer’s Systems during such Contract Quarter and attributable to the interests of each owner (other than a GMX Party) of a Working Interest, royalty interest, or other interest in oil and Gas, to the
extent such volumes of Gas are not owned or Controlled by a GMX Party or Shipper and, thus, not subject to the terms of this Agreement; plus (iii) the applicable Adjustment Percentage of the volumes of Gas gathered on Gatherer’s
Systems during such Contract Quarter that are produced from wells in which no GMX Party owns an interest but as to which Shipper is the first Gas purchaser or is otherwise authorized to market Gas production. 
 (d) For purposes of this Agreement, the term “Adjustment Percentage” means the percentage, not greater than 100%,
calculated as the ratio, the numerator of which is the “gathering” or similar fee, per MMBtu, payable under the terms of gas gathering agreements to which the Gas referred to in clauses (ii) and (iii) of Article
1.7(c) is subject, and the denominator of which is the Gathering Fee set forth in Article 2.1. 
 1.8 Nominations
and Scheduling. No later than five (5) Business Days prior to the end of each month during the Term, Shipper shall deliver, or cause to be delivered, to Gatherer written notice containing (a) Shipper’s estimate of the quantity of
Dedicated Gas, in Mcf and MMBtu, to be made available hereunder at each Receipt Point on each Day of the next succeeding month (“Receipt

  

 - 6 - 

 
Nominations”) and (b) Shipper’s estimate of the quantity of Gas, in MMBtu, that Shipper desires Gatherer to deliver at each Delivery Point and each Reinjection Point on each
Day of the next succeeding Month (“Delivery Nominations”). Shipper shall also be responsible for making, or causing to be made, all necessary arrangements with the Downstream Pipelines in order to effectuate Gatherer’s delivery
of Gas at the Delivery Points. Shipper shall coordinate such arrangements with Gatherer. Shipper shall keep Gatherer informed as necessary during the month of production of material changes in the Receipt Nominations and the corresponding changes in
the Delivery Nominations. Gatherer shall receive at the Receipt Points and deliver at the Delivery Points and Reinjection Points all Gas gathered under this Agreement on a pro rata basis unless Shipper’s Receipt Nominations or Delivery
Nominations for the relevant month specify a priority among Receipt Points, Delivery Points, or Reinjection Points, as applicable, in which Shipper’s receipts or deliveries of Gas should be scheduled, in which case Gatherer shall use reasonable
commercial efforts to receive and deliver Gas according to Shipper’s specified priorities. All Delivery Nominations shall conform, in form and substance, to the nomination requirements of the Downstream Pipeline to which they are directed. All
Receipt Nominations and Delivery Nominations may be submitted by Shipper by facsimile or electronically in any manner consistent with the requirements of the relevant Downstream Pipelines. 
 1.9 Excess Capacity. Shipper shall have first priority rights with respect to the capacity in Gatherer’s Systems.
Notwithstanding the preceding sentence of this Article 1.9, if, for any period during the Term, there exists any throughput capacity in Gatherer’s Systems that, as determined by Gatherer (taking into account the volumes of Gas made
available by Shipper at the Receipt Points during the preceding two (2) months, Shipper’s current Receipt Nomination, Shipper’s current level of drilling activity on the Dedicated Acreage, and Shipper’s anticipated gathering
requirements for the succeeding three (3) months), is not required to accommodate the volumes of Dedicated Gas expected to be made available by Shipper at the Receipt Points hereunder or to perform any gathering agreement with any third Person
pertaining to Gatherer’s Systems then in existence, Gatherer shall have the exclusive right to market and make available to other Persons, for Gatherer’s own account, such excess capacity on such terms and conditions as Gatherer may
determine. No such third Person gathering agreement shall create obligations inconsistent with, or impair the ability of Gatherer to perform, Gatherer’s obligations under this Agreement; provided, however, that the inclusion in any such third
Person gathering agreement of economic terms different from those contained in this Agreement shall not constitute such an inconsistency for purposes hereof. 
 ARTICLE II 
 FEES AND REIMBURSEMENT 
 2.1 Gathering Fee. Each month during the Term, Shipper shall pay to Gatherer an amount (the “Gathering Fee”) equal
to the product obtained by multiplying (a) all volumes of Dedicated Gas, in MMBtu, delivered by Shipper to Gatherer at the Receipt Points, less all volumes of Dedicated Gas delivered to the Reinjection Points during the relevant
month, by (b) the Gathering Rate for such month. 
  

 - 7 - 

 2.2 Compression Fee. In addition to the Gathering Fee, each month during the Term,
Shipper shall pay to Gatherer an amount (the “Compression Fee”) equal to the product obtained by multiplying (a) all volumes of Dedicated Gas, in MMBtu, delivered by Shipper to Gatherer at the Receipt Points of
the Low Pressure Pipelines during the relevant month, less all volumes of Dedicated Gas delivered to the Reinjection Points during such month, by (b) the number of stages of compression at the compression facilities on the Low Pressure
Pipelines, by (c) the Compression Rate. For purposes of this Agreement, Gatherer’s compression facilities connected to the Low Pressure Pipelines shall be deemed to provide three (3) stages of compression. If, during the Term,
compression other than in connection with the Low Pressure Pipeline is provided on Gatherer’s Systems through facilities in operation as of the Effective Date, the Compression Fee payable with respect to such other compression shall be equal to
the product obtained by multiplying (x) the volume of Dedicated Gas, in MMBtu, measured at the inlet flange of such other compression facilities, by (y) the number of stages of compression at such other facilities,
by (z) the Compression Rate. 
 2.3 Fuel. Each month during the Term, Shipper shall be responsible for
Shipper’s proportionate share of all Fuel. For purposes of this Agreement, “Fuel” means a volume of Gas, in MMBtu, calculated as the positive difference (if any) obtained by subtracting (a) the Equivalent
Quantities delivered during the relevant month by Gatherer to Shipper as measured at the Delivery Points and Reinjection Points, from (b) the quantities of Dedicated Gas delivered during such month by Shipper to Gatherer as measured at
the Receipt Points. Gatherer acknowledges that the Fuel satisfies all Claims by, or requirements of, Gatherer for any fuel used in gathering, metering, compressing, dehydrating, heating, and redelivering the Dedicated Gas, as well as any Gas lost or
unaccounted for on Gatherer’s Systems. To the extent that Gas owned by Persons other than the GMX Parties or Shipper is gathered on Gatherer’s Systems pursuant to Article 1.9, all such third Persons shall be allocated their
respective proportionate shares of Fuel, calculated in the same manner as set forth in this Article 2.3. 
 2.4 Other
Charges. If the GMX Parties or Shipper fund an Expansion Project in accordance with Article 1.3(d), then Shipper shall pay to Gatherer, each month during the Term after the in-service date for such Expansion Project, the Expansion Project
Operating Charges incurred during the preceding month. 
 2.5 Allocations. Gatherer shall be responsible for providing to
Shipper allocations to each Receipt Point of the Gathering Fees, Compression Fees, and Fuel paid or provided by Shipper each month during the Term, based on the volumes of Dedicated Gas delivered by Shipper as measured at the Receipt Points. Any
further allocations of such Gathering Fees, Compression Fees, or Fuel upstream of the Receipt Points shall be the responsibility of Shipper. 
 ARTICLE III 
 RECEIPT AND DELIVERY POINTS 
 3.1 Receipt Points. The “Receipt Points” for all Gas delivered by Shipper to Gatherer hereunder shall be at the
inlet flange to the custody transfer meter for each well on the Dedicated Acreage identified as a “Receipt Point” in Exhibit C-1, as the same may be amended from to time. Receipt Points for the Low Pressure Pipelines are identified
in Exhibit C-1(a), and Receipt Points for the High Pressure Pipelines are identified in Exhibit C-1(b). 
  

 - 8 - 

 3.2 Delivery Points. The “Delivery Points” for all Gas delivered by
Gatherer to Shipper hereunder for sale or transportation shall be at the points of interconnection between Gatherer’s Systems and the Downstream Pipelines designated in Exhibit C-2, as the same may be amended from time to time.

 3.3 Reinjection Points. The “Reinjection Points” for Gas delivered by Gatherer to Shipper hereunder
for Gas lift operations shall be at the outlet flange of each of the custody transfer meters for the wells on the Dedicated Acreage identified as a “Reinjection Point” in Exhibit C-3, as the same may be amended from time to time.

 ARTICLE IV 
 POSSESSION OF GAS 
 4.1 Shipper’s Responsibility. As between
Shipper and Gatherer, Shipper shall be in exclusive control and possession of the Dedicated Gas (a) prior to the receipt of the Dedicated Gas by Gatherer at the Receipt Points, and (b) at and after the redelivery of such Gas by Gatherer to
Shipper at the Reinjection Points or to or for the account of Shipper at the Delivery Points. 
 4.2 Gatherer’s
Responsibility. Gatherer shall be in exclusive control and possession of the Dedicated Gas at and after the receipt of the Dedicated Gas by Gatherer at the Receipt Points and prior to the redelivery thereof to Shipper at the Reinjection Points
or to or for the account of Shipper at the Delivery Points. Gatherer shall not, however, become vested with title to any Gas gathered under the terms of this Agreement. 
 4.3 Indemnities. 
 (a) As between Shipper and Gatherer, Shipper or Gatherer
shall be responsible for any damage or injury caused by the Dedicated Gas while such Party is deemed to be in exclusive control and possession thereof pursuant to this Article IV. Each Party in possession and control of the Dedicated Gas
assumes all Liability for, and shall indemnify, defend, and hold harmless the other Party and its Indemnity Group from and against, any and all Claims and Liabilities relating to injury to or death of any Person(s) or other living things or damage
to or loss or destruction of property (including pollution, contamination, and other damage to the environment) arising from any act or incident related to the Dedicated Gas while such Gas is in the exclusive control and possession of the
indemnifying Party, to the extent not due to or contributed to by the negligent act or omission or willful misconduct of the indemnified Party. 
 (b) The GMX Parties and Shipper, on the one hand, and Gatherer, on the other hand, assume full responsibility for, and Liability arising from, the design, fabrication, installation, construction,
ownership, operation, maintenance, repair, replacement, relocation, modification, abandonment, and removal of their respective facilities as provided in this Agreement. The GMX Parties and Shipper shall indemnify, defend, and hold harmless Gatherer
and its Indemnity Group, and Gatherer shall indemnify, defend, and hold harmless the GMX Parties and Shipper and their respective Indemnity Groups, in each case from and against any Claim or Liability (except as otherwise specifically provided in
this Agreement) that the indemnified Party incurs on account of any such design, fabrication, installation, construction, ownership, operation, maintenance, repair, replacement, relocation, modification,

  

 - 9 - 

 
abandonment, or removal of the indemnifying Party’s facilities, to the extent not due to or contributed to by the negligent act or omission or willful misconduct of the indemnified Party.
However, no Party shall be liable to any other Party for, or indemnify and hold harmless any other Party from, any Claims and Liabilities arising out of acts or omissions of third Persons when such acts or omissions are not reasonably within the
indemnifying Party’s control. 
 ARTICLE V 
 TERM 
 5.1 Term. 
 (a) Subject to the other provisions of this Agreement, unless earlier terminated as provided herein, this Agreement shall
be effective as of 9:00 a.m., Central Clock Time, on the Effective Date and shall remain in full force and effect for an initial term (the “Initial Term”) ending at 9:00 a.m., Central Clock Time, on the later of (a) one
month after the tenth (10th) anniversary of the
Effective Date, or (b) the first Day of the month following the month in which the total cumulative quantities of Dedicated Gas delivered by Shipper to Gatherer at the Receipt Points, less the total cumulative quantities of Dedicated Gas
delivered by Gatherer to Shipper at the Reinjection Points, equals the Target Quantity. At the expiration of the Initial Term, this Agreement shall nevertheless remain in full force and effect for an additional period of ten (10) Contract Years
(the “Initial Term Extension”). After the expiration of the Initial Term Extension, this Agreement shall remain in full force and effect on a Contract Year-by-Contract Year basis (each a “Year-to-Year Extension”),
unless and until terminated by either Party upon delivery to the other Party of written notice of such intent to terminate not less than ninety (90) Days prior to the expiration of the Initial Term Extension or the last Day of the relevant
Contract Year thereafter, as applicable. The Initial Term, together with the Initial Term Extension and each Year-to-Year Extension, will be referred to collectively herein as the “Term”. 
 (b) At the expiration of the Initial Term, Shipper and Gatherer shall enter into good faith negotiations to amend the commercial and other
terms of this Agreement on which the Initial Term Extension and the Year-to-Year Extensions should be based. If the Parties are unable to agree on such amended commercial and other terms, however, this Agreement shall nevertheless remain in force
and effect as provided in Article 5.1(a) on the same terms as in effect at the expiration of the Initial Term; provided, that, there shall be no Volume Shortfall Payments owed by Shipper to Gatherer for any period after the Initial Term.

 5.2 Early Termination. A Party (the “Non-Affected Party”) may immediately terminate this Agreement
prior to the expiration of the Term upon the occurrence of any of the following events with respect to the other Party (the “Affected Party”): 
 (a) the failure by the Affected Party to make, when due, any payment required herein, and such failure is not cured within five (5) Business Days after written notice thereof to the Affected Party;

  

 - 10 - 

 (b) the failure by the Affected Party to perform any covenant herein (other than payment
obligations specifically covered in Article 5.2(a)), and such failure is not the result of a good faith dispute or excused by Force Majeure or cured within sixty (60) Days after written notice thereof to the Affected Party; or

 (c) the Affected Party shall: 
  

	 	(i)	make an assignment or any general arrangement for the benefit of creditors; 

  

	 	(ii)	file a petition or otherwise commence, authorize, or acquiesce in the commencement of a proceeding or cause under any bankruptcy or similar law for the protection of
creditors, or have such a petition filed against it, and such proceeding remains un-dismissed for thirty (30) Days; 

  

	 	(iii)	otherwise become bankrupt or insolvent (however evidenced); or 

  

	 	(iv)	be unable to pay its debts as they fall due. 

 This right to terminate shall be in addition to the rights of the Non-Affected Party to (v) seek indemnification from the Affected Party when permitted to do so hereunder, (w) file suit to recover damages, (x) enforce any
security provided by the Affected Party to secure the Affected Party’s performance hereunder, (y) withhold any payments due or any performance owed (including suspension of receipts or deliveries of Gas) to the Affected Party, and
(z) pursue any other right, remedy, or measure of damages available to the Non-Affected Party hereunder, at Law, or in equity as a result of the occurrence of one of the events listed above with respect to the Affected Party. The rights and
remedies provided by this Agreement are cumulative, and any Party’s use of any right or remedy will not preclude or waive its right to use any other right or remedy. Notwithstanding the early termination of this Agreement pursuant to this
Article 5.2, if such early termination occurs prior to the expiration of the Initial Term, Shipper shall nevertheless remain obligated to make Volume Shortfall Payments to Gatherer in accordance with Article 1.7 until the sum of
the Actual Gathered Volumes delivered by Shipper to Gatherer prior to the early termination of this Agreement, plus the aggregate Benchmark Volumes used in calculating Volume Shortfall Payments payable after such early termination
equals the Target Quantity. 
 5.3 Setoff. Each Party reserves to itself all rights, set-offs, counterclaims, and
other remedies and defenses which such Party has or may be entitled to arising from or out of this Agreement. Upon the occurrence of an event described above in Article 5.2, all outstanding transactions between the Parties and the obligations
to make payment in connection therewith, whether arising under this Agreement or the Pipeline Operating Agreement, may be offset against each other, set off, or recouped therefrom upon notice to the affected Party detailing the amounts set off and
the obligations for which such set-off has occurred. 
 5.4 Survival. Upon the termination of this Agreement, the
obligations of the Parties under the following provisions shall survive such termination for a period equal to the applicable statute(s) of limitation: Articles 1.3(d), 4.3, 5.3, 5.4, 5.5, VI, 7.2,
7.4, 7.6, 7.12, 7.13, 7.14, 7.17; Sections II.5, V.2, VII.5, VIII, XI.2, and XIII of Annex I. 
  

 - 11 - 

 5.5 Disconnection of Facilities. The termination of this Agreement, or any other
event occurring pursuant to the provisions of this Agreement resulting in the discontinuance of the receipt, gathering and delivery of Gas hereunder, shall be deemed a consent by Shipper to the disconnection of Gatherer’s facilities under
Statewide Rule 73 of the Conservation Rules and Regulations of the Railroad Commission of Texas (or any successor rule or ordinance), if and to the extent such rule is ever interpreted to govern transaction(s) of the type evidenced hereby.

 (iii) to the other owners of interests in the Dedicated Gas,
provided that such owners of interest shall be made aware of and agree to maintain the confidential nature of this Agreement; and 
 (iv) any potential purchasers of the Leases or other assets and/or equity interests of Shipper or Gatherer, provided that the selling Party shall be fully responsible for maintaining the confidentiality
of this Agreement by such potential purchasers. 
 (b) The Parties acknowledge that, from time to time, they may receive
information from or regarding any of the other parties or their Affiliates in the nature of trade secrets or secret or proprietary information or information that is otherwise confidential, the release of which may be damaging to the disclosing
Party or its Affiliates, as applicable (collectively, the “Disclosing Party”). Each Party (as applicable, the “Receiving Party”) shall hold in strict confidence any such information it receives for a period of two
(2) years following the receipt of such information and, during such time period, may not disclose such information to any Person, except for disclosures (i) to comply with any Laws (including applicable stock exchange or quotation system
requirements), (ii) to Affiliates, advisers or representatives of the Receiving Party, but only if the recipients of such information have agreed to be bound by the provisions of this Article 7.2(b) as an additional Receiving Party,
(iii) of information that a Receiving Party also has received from a source independent of the Disclosing Party and that such Receiving Party reasonably believes such source obtained

  

 - 14 - 

 
without breach of any obligation of confidentiality, (iv) of information obtained prior to the execution of this Agreement, provided that this clause (iv) shall not relieve any
Receiving Party or any of its Affiliates from any obligations it may have to any other Party or any of its Affiliates under any existing confidentiality agreement, (v) to lenders, accountants and other representatives of the Receiving Party
with a need to know such information, provided that the Receiving Party shall be responsible for such representatives’ use and disclosure of any such information, (vi) of public information, or (vii) in connection with any
proposed assignment of the rights and obligations under this Agreement, to advisers or representatives of the Receiving Party, its parent or Persons to which such rights and obligations may be assigned as permitted by this Agreement, but only if the
recipients of such information have agreed in writing to be bound by confidentiality provisions that are no less stringent than those set forth in this Article 7.2(b). The Parties acknowledge that a breach of the provisions of this
Article 7.2(b) by a Receiving Party may cause irreparable injury to the Disclosing Party for which monetary damages are inadequate, difficult to compute, or both. Accordingly, the Parties agree that the provisions of this
Article 7.2(b) may be enforced by injunctive action or specific performance, and the Parties hereby waive any requirement to post bond in connection with any injunctive order or order for specific performance. 
 7.3 Assignment. This Agreement, and the rights created and assigned hereby, may be assigned, in whole or in part, by the GMX Parties,
Shipper, or Gatherer; provided, however, that any such assignment by Shipper or the GMX Parties shall expressly require the prior written consent of Gatherer; any such assignment by Gatherer shall expressly require the prior written consent of GMX;
and each assignee shall assume and agree to discharge the duties and obligations of its assignor under this Agreement. Such consent shall not be unreasonably withheld, conditioned, or delayed. Notwithstanding the foregoing, any Party shall have the
right, without the consent of any other Party, (a) to assign this Agreement, in whole but not in part, to an Affiliate, and (b) to pledge, assign, grant a security interest in, or otherwise encumber its rights and interests under this
Agreement in connection with any financing or other financial arrangement. In addition, the terms of this Agreement shall be covenants running with the land and shall be binding upon and inure to the benefit of the successors, assigns, heirs,
personal representatives, and representatives in bankruptcy of any GMX Party with respect to the oil and gas leases covering the lands located within the Area of Interest in which a GMX Party acquires an interest during the Term. Notwithstanding any
other provision of this Article 7.3, the GMX Parties may, without the prior written consent of Gatherer, assign all or any portion of their respective rights and interests under this Agreement in connection with any assignment by a GMX
Party of any of the Leases; provided that the assignee or transferee expressly agrees in writing to assume and to pay, perform, and discharge its proportionate share of the duties, obligations, and responsibilities of the assigning GMX Party under
this Agreement. The permitted transfer or assignment of this Agreement under this Article 7.3 shall not relieve the assigning Party of any obligations or Liabilities hereunder (whether or not accrued at the effective time of the
transfer). Upon the assumption by the transferee of the duties, obligations, and responsibilities of the assigning Party under this Agreement, the transferee shall become primarily liable for all future duties, obligations, and responsibilities
assumed. If, however, the transferee fails to perform any of the duties, obligations, or responsibilities thus assumed, the assigning Party shall remain liable for the performance thereof; provided, however, that upon a total assignment of a
Party’s duties, obligations, and responsibilities hereunder, the assigning Party shall be

  

 - 15 - 

 
released from any further liability for the performance thereof upon the written consent of the other Party, which shall not be unreasonably withheld, conditioned, or delayed, and it shall be
reasonable for a Party to withhold its consent with respect to a proposed assignee pursuant to this proviso if such proposed assignee (x) does not have credit reasonably satisfactory to such Party, or (y) does not have the expertise,
manpower, and means to perform this Agreement according to its terms. No such assignment, or any succession to the interest of any Party, shall be effective and binding until the other Parties are furnished with proper and satisfactory evidence of
such assignment or succession. Subject to the preceding provisions of this Article 7.3, all covenants, stipulations, terms, conditions and provisions of this Agreement shall extend to and be binding upon the respective successors, assigns,
heirs, personal representatives, and representatives in bankruptcy of the Parties. 
 7.4 DAMAGES. UNLESS OTHERWISE
EXPRESSLY HEREIN PROVIDED, EACH PARTY’S LIABILITY TO THE OTHER PARTIES UNDER THIS AGREEMENT SHALL BE LIMITED TO DIRECT ACTUAL DAMAGES ONLY, SUCH DIRECT ACTUAL DAMAGES SHALL BE THE SOLE AND EXCLUSIVE REMEDY HEREUNDER, AND ALL OTHER REMEDIES OR
DAMAGES AT LAW OR IN EQUITY ARE WAIVED. UNLESS EXPRESSLY HEREIN PROVIDED, NO PARTY SHALL BE LIABLE FOR CONSEQUENTIAL, INCIDENTAL, PUNITIVE, EXEMPLARY, OR INDIRECT DAMAGES, LOST PROFITS OR OTHER BUSINESS INTERRUPTION DAMAGES, WHETHER IN CONTRACT, IN
TORT, UNDER ANY INDEMNITY PROVISION, OR OTHERWISE. 
 7.5 Entire Agreement. This Agreement, together with the
Other Transaction Documents, constitutes the entire agreement of the Parties, and supersedes (a) all prior oral or written proposals or agreements, (b) all contemporaneous oral proposals or agreements, and (c) all previous
negotiations and all other communications or understandings between the Parties, with respect to the subject matter hereof. 
 7.6 GOVERNING LAW; CONSENT TO VENUE. THIS AGREEMENT HAS BEEN EXECUTED AND DELIVERED, AND SHALL BE CONSTRUED, INTERPRETED AND GOVERNED, PURSUANT TO AND IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS, WITHOUT REGARD TO ANY
CONFLICT OF LAWS PRINCIPLES WHICH, IF APPLIED, MIGHT PERMIT OR REQUIRE THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION. THE PARTIES SHALL USE REASONABLE EFFORTS TO RESOLVE ANY DISPUTE OR CLAIM WHICH MAY ARISE UNDER THIS AGREEMENT IN AN AMICABLE
MANNER. EXCEPT AS OTHERWISE PROVIDED IN SECTION VIII OF ANNEX I, AS TO ANY DISPUTE OR CLAIM ARISING OUT OF OR IN RELATION TO THIS AGREEMENT WHICH IS NOT AMICABLY SETTLED, THE PARTIES AGREE THAT ANY DISPUTE ARISING OUT OF OR CONNECTED WITH THIS
AGREEMENT SHALL BE ADJUDICATED IN THE STATE OR FEDERAL COURTS SITTING IN HARRIS COUNTY IN THE STATE OF TEXAS, AND VENUE SHALL AT ALL TIMES BE PROPER THERE. 
 7.7 No Third Party Beneficiaries. This Agreement is for the sole and exclusive benefit of the Parties and Kinder Morgan Endeavor LLC. No such third party beneficiary shall have any obligation or
liability of any kind or character under the terms of this

  

 - 16 - 

 
Agreement, however, except for those specifically acknowledged by such third party beneficiary. Except as otherwise expressly provided herein, nothing herein is intended to benefit any other
Person not a Party hereto, and no such Person shall have any legal or equitable right, remedy, or Claim under this Agreement. 
 7.8 Exhibits. All exhibits contained in or attached to this Agreement are integrally related to this Agreement and are hereby made a part of this Agreement for all purposes. To the extent of any ambiguity, inconsistency or conflict
between the body of this Agreement and any of the exhibits attached to this Agreement, the terms of the body of this Agreement shall prevail. 
 7.9 Articles and Sections. Unless otherwise expressly stated herein, all references contained herein to articles and subdivisions thereof shall be to articles or subdivisions of the body of this
Agreement, and all references herein to sections and subdivisions thereof shall be to sections of the GENERAL TERMS AND CONDITIONS appearing at Annex I. 
 7.10 Further Assurances. Each Party agrees to do all acts and things and to execute and deliver such further documents as may be from time to time reasonably required to carry out the terms and
provisions of this Agreement. 
 7.11 Time of the Essence. Time is of the essence with respect to any and all obligations
arising pursuant to this Agreement. 
 7.12 Integrated Transaction. Each Party has entered into this Agreement in
consideration of (a) the covenants and conditions set forth herein, the receipt and sufficiency of which are hereby acknowledged, and (b) the execution, delivery, and performance by various parties of the Purchase Agreement, the Services
Agreement, the Pipeline Operating Agreement, and the other contracts and agreements among the parties contemplated therein and/or executed in connection therewith (collectively, the “Other Transaction Documents”). The Parties agree
that no Party would have entered into this Agreement without the Other Transaction Documents; the consideration for entering into this Agreement forms part of the consideration for entering into the Other Transaction Documents; and if, in the event
of the bankruptcy of any Party, this Agreement and the Other Transaction Documents are determined to be executory contracts, this Agreement and the other Transaction Documents must be rejected or assumed together. 
 7.13 Forward Contracts. The Parties agree that the transactions contemplated in this Agreement constitute a “forward
contract” within the meaning of the United States Bankruptcy Code, and that each Party is a “forward contract merchant” within the meaning of the United States Bankruptcy Code. 
 7.14 Bankruptcy Stay Waiver. Each Party agrees that, if it should become a debtor in a bankruptcy proceeding, it expressly
waives the provisions of Section 362 of the Bankruptcy Code as the same pertains to this Agreement. The automatic stay shall not apply to any rights or remedies asserted by the other Party in connection with this Agreement. 
 7.15 No Waiver. Neither action taken (including any investigation by or on behalf of any Party) nor inaction pursuant to this
Agreement shall be deemed to constitute a waiver of compliance with any representation, warranty, covenant or agreement contained herein by the Party not committing such action or inaction. A waiver by any Party of a particular right, including
breach of any provision of this Agreement, shall not operate or be construed as a subsequent waiver of that same right or a waiver of any other right. 
  

 - 17 - 

 7.16 Amendments. This Agreement shall not be altered or amended, except by an
agreement in writing executed by all Parties. 
 7.17 Public Announcements and Disclosure. GMX shall consult with Kinder
Morgan Endeavor LLC before GMX or any of its Affiliates issues any press release or otherwise makes any public statement or filing with a Governmental Entity with respect to this Agreement, the Other Transaction Documents, or the transactions
contemplated hereby and thereby. GMX and its Affiliates shall not issue any such press release or make any such public statement or filing without the prior consent of Kinder Morgan Endeavor LLC, which consent shall not be unreasonably withheld or
delayed, except as may be required by Law or applicable rule of any stock exchange. 
 7.18 Construction. The Parties
hereby stipulate and agree that each of them fully participated and was adequately represented by counsel in the negotiation and preparation of this Agreement, and the Parties further stipulate and agree that in the event of an ambiguity or other
necessity for interpretation to be made of the content of this Agreement, this Agreement shall not be construed in favor of or against any Party as a consequence of one Party having had a greater role in the preparation of this Agreement, but shall
be construed as if the language were mutually drafted by all the Parties with full assistance of counsel. 
 7.19
Severability. If one or more of the provisions contained in this Agreement are for any reason held by a court of competent jurisdiction to be invalid, illegal, or unenforceable in any respect, the invalidity, illegality, or unenforceability
will not affect any other provision of this Agreement, which will be construed as if it had not included the invalid, illegal, or unenforceable provision. 
 7.20 Counterparts. This Agreement may be executed in any number of counterparts, and each such counterpart hereof shall be deemed to be an original instrument, but all of such counterparts shall
constitute for all purposes one agreement. At the Parties’ election, this Agreement may be executed by the Parties in different locations and shall become binding upon both Parties upon the exchange by the Parties of executed signature pages by
facsimile. In the event of such a facsimile execution, the Parties shall execute and deliver each to the other a fully executed original counterpart of this Agreement within thirty (30) days after such facsimile execution hereof; provided,
however, that the failure of the Parties to execute such an original counterpart of this Agreement shall not affect or impair the binding character or enforceability of this Agreement.
