Except to the extent a Claim (or Claims) is covered by the indemnity in the preceding sentence, Gatherer agrees to indemnify, defend, and hold harmless Producers and their Affiliates from all Claims arising from or out of bodily injury or property damage attributable to Producers’ Gas and MV Mitigation Gas when Gatherer shall be deemed to be in control and possession of Producers’ Gas and MV Mitigation Gas as provided in Section 6.1. In addition, Gatherer agrees to indemnify, defend, and hold harmless Producers and

their Affiliates from all Claims asserted by Surface Estate Owners arising out of Gatherer’s use of the easements and rights of way that are assigned to Gatherer from time to time pursuant to Section 12.12. THE INDEMNITIES SET FORTH IN THIS SECTION 6.2 ARE TO BE CONSTRUED WITHOUT REGARD TO THE CAUSES THEREOF, INCLUDING, WITHOUT LIMITATION, THE NEGLIGENCE OF ANY INDEMNIFIED PARTY, WHETHER SUCH NEGLIGENCE BE SOLE, JOINT OR CONCURRENT, OR ACTIVE OR PASSIVE, OR THE STRICT LIABILITY OF ANY INDEMNIFIED PARTY OR OTHER PERSON.

6.3 Waiver of Damages. A PARTY’S LIABILITY UNDER THIS AGREEMENT SHALL BE LIMITED TO DIRECT ACTUAL DAMAGES ONLY. NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY OR ITS AFFILIATES FOR CONSEQUENTIAL, INCIDENTAL, PUNITIVE, EXEMPLARY, OR INDIRECT DAMAGES, LOST PROFITS, OR OTHER BUSINESS INTERRUPTION DAMAGES, BY STATUTE, IN TORT, OR CONTRACT, UNDER ANY INDEMNITY PROVISION OR OTHERWISE, ALL OF THE SAME BEING HEREBY EXPRESSLY WAIVED AND NEGATED. IT IS THE INTENT OF THE PARTIES THAT THE LIMITATIONS HEREIN IMPOSED ON REMEDIES AND THE MEASURE OF DAMAGES BE WITHOUT REGARD TO THE CAUSE OR CAUSES RELATED THERETO, INCLUDING THE STRICT LIABILITY OR NEGLIGENCE OF ANY PARTY, WHETHER SUCH STRICT LIABILITY OR NEGLIGENCE BE SOLE, JOINT OR CONCURRENT, OR ACTIVE OR PASSIVE. TO THE EXTENT ANY DAMAGES REQUIRED TO BE PAID HEREUNDER ARE LIQUIDATED, THE PARTIES ACKNOWLEDGE THAT THE DAMAGES ARE DIFFICULT OR IMPOSSIBLE TO DETERMINE, OR OTHERWISE OBTAINING AN ADEQUATE REMEDY IS INCONVENIENT, AND THE DAMAGES CALCULATED HEREUNDER CONSTITUTE A REASONABLE APPROXIMATION OF THE HARM OR LOSS. The waiver in this Section 6.3 shall not limit or otherwise affect Producers’ and Gatherer’s rights and obligations under Section 10.2.

7.1 Billing. As soon as practicable each Month, Gatherer shall invoice Producers in electronic format for services provided hereunder in the preceding Month and provide a statement setting forth (i) the volumes and quantities (expressed in Mcf’s and MMBtu’s) of Producers’ Gas and MV Mitigation Gas received at each Receipt Point and redelivered to each Delivery Point and the volumes and quantities of System Fuel and Losses, if measured or ascertainable by Gatherer, (ii) the Fees for such Producers’ Gas and MV Mitigation Gas, (iii) any adjustments for prior periods, and (iv) all amounts due by Producers hereunder. If actual measurements of volumes of Producers’ Gas or MV Mitigation Gas are not available by the 15^th Day of the Month following the Month of receipt by Gatherer, then, on or after such 15^thDay (or if such Day is not a Business Day, on or after the next Business Day), Gatherer may prepare and submit its invoice based on Gatherer’s good faith estimate of the volumes of Producers’ Gas and MV Mitigation Gas received in such Month. If Gatherer submits an invoice based on estimated volumes, Gatherer shall prepare and submit to Producers an invoice based on actual measurements on or before the close of business, CPT, of the 45^th Day (or if such 45^th Day is not a Business Day, on the following Business Day) after the applicable Month of delivery of

Producers’ Gas or MV Mitigation Gas. Gatherer’s invoices shall include information reasonably sufficient to explain and support any estimates and charges reflected therein, the reconciliation of any estimates made in a prior Month to any actual measurements, and any adjustments to prior period volumes and quantities. Gatherer will use its commercially reasonable efforts to take such actions as may be appropriate to permit Gatherer by June 30, 2011 to submit invoices for actual volumes of Producers’ Gas and MV Mitigation Gas received, gathered, and handled hereunder not later than the close of business, CPT, on the 15th day of the Month following the Month of delivery of Producers’ Gas or MV Mitigation Gas.

7.2 Payment. Producers shall remit to Gatherer the amount due under Section 7.1, by wire transfer by the 25^th Day of each Month or 10 Days from the date of receipt of Gatherer’s electronic invoice, whichever is later. If such due date is not a Business Day, payment is due on the next Business Day following such date.

7.3 Dispute. If Producers, in good faith, dispute the amount of any invoice of Gatherer that is based on actual measurements (not estimated volumes) or any part thereof, Producers will pay Gatherer such amount, if any, that is not in dispute and shall provide Gatherer Notice, no later than within 30 Days after the date that payment of such invoice would be due under Section 7.2, of the disputed amount accompanied by supporting documentation acceptable in industry practice to support the disputed amount. If the Parties are unable to resolve such dispute, either Party may pursue any remedy available at law or in equity to enforce its rights under this Agreement. If Notice of a disputed invoice is not furnished to Gatherer by the date above, Producers shall be deemed to have waived the right to dispute such invoice, subject to Producers’ rights under Section 7.5 below.

7.4 Late Payments. If Producers fail to pay the amount of any invoice rendered by Gatherer hereunder when such amount is due, interest thereon shall accrue from, but excluding, the due date to and including the date payment thereof is actually made at the lesser of the Prime Rate plus 2%, computed on an annualized basis and compounded Monthly, or the maximum rate of interest permitted by Applicable Law, not to exceed the maximum legal rate. “Prime Rate” means the prime rate on corporate loans at large U.S. money center commercial banks as set forth in The Wall Street Journal “Money Rates” table under the Heading “Prime Rate,” or any successor thereto, on the first date of publication for the Month in which payment is due. Gatherer shall render a late payment charge invoice and Producers shall make payment upon receipt of such invoice.

7.5 Audit. Each Party or its designated representatives shall have the right, at its own expense, upon reasonable Notice and at reasonable times, to examine and audit and to obtain copies of the relevant portion of the books, records (including electronic measurement data, meter charts or records and other similar information supporting relevant calculations), and telephone recordings of the other Party and its Affiliates to the extent reasonably necessary to verify the accuracy of any statement, charge, payment, or computation made under this Agreement. This right to examine, audit, and to obtain copies shall not be available with respect to information not directly relevant to transactions under this Agreement. All invoices and billings, adjusted as contemplated in accordance with the second sentence of Section 7.1, shall be conclusively presumed final and accurate and all associated claims for underpayments or overpayments shall be deemed waived unless such invoices or billings are objected to in writing,

with adequate explanation and/or documentation, within two Years after the Month of Gas delivery. Any retroactive adjustment made in response to information furnished under an audit under this Section 7.5 shall be paid in full by the Party owing payment within 30 Days of Notice and substantiation of such inaccuracy.

7.6 Minor Adjustments. No adjustments, retroactive or prospective, shall be made to volumes for prior periods, whether the result of volume allocation errors or any other reason other than meter calibration error, that involve changes that would be less than 100 Mcf’s per Month.

7.7 Financial Responsibility. If (i) Producers fail to pay according to the provisions hereof and such failure continues for a period of 5 Business Days after Notice of such failure is provided to Producers or (ii) Gatherer has reasonable grounds for insecurity regarding the performance by Producers of any obligation under this Agreement, then Gatherer, by Notice to Producers, may, singularly or in combination with any other rights it may have, demand Adequate Assurance of Performance by Producers. “Adequate Assurance of Performance” means, at the option of Producers, (x) advance payment in cash by Producers to Gatherer for services to be provided under this Agreement in the following Month or (y) delivery to Gatherer by Producers of an Acceptable Letter of Credit in an amount equal to not less than the aggregate proceeds due from Producers under Section 7.2 for the prior 2 Month period. If Gatherer reasonably believes Producers will not deliver the Barnett Annual Minimum Volume for the Barnett Gathering Systems in such Year, Gatherer may require that any advance payment in cash by Producers to Gatherer be in an amount up to the aggregate proceeds due from Producers under Section 7.2 for the prior 2 Month period and that any Acceptable Letter of Credit be in an amount up to the aggregate proceeds paid by Producers under Section 7.2 for the prior 3 Month period. If Producers fail to provide Adequate Assurance of Performance to Gatherer within 48 hours of Gatherer’s Notice or if Producers or CHK Parent suffer any of the actions set forth in Section 2.2(v), then Gatherer shall have the right to suspend or reduce all services under this Agreement without prior Notice and without limiting any other rights or remedies available to it under this Agreement or otherwise. If Gatherer exercises the right to suspend or reduce services under this Section 7.7, then Producers shall not be entitled to take, or cause to be taken, any action hereunder or otherwise against Gatherer for such suspension or reduction. Failure of Gatherer to exercise its right to suspend or reduce service as provided in this Section 7.7 shall not constitute a waiver by Gatherer of any rights or remedies Gatherer may have under this Agreement, Applicable Law, or otherwise.

8.1 Non-Performance. If a Party is rendered unable, wholly or in part, by reason of a Force Majeure Event to perform its obligations under this Agreement, other than Producers’ obligations to make payments when due hereunder, then such Party’s obligations shall be suspended to the extent affected by the Force Majeure Event.

8.2 Definition. “Force Majeure Event” means any cause or event not reasonably within the control of the Party whose performance is sought to be excused thereby including the following causes and events (to the extent such causes and events are not reasonably within the

control of the Party claiming suspension): acts of God, strikes, lockouts, or other industrial disputes or disturbances, acts of the public enemy, wars, blockades, insurrections, civil disturbances and riots, epidemics, landslides, lightning, earthquakes, fires, tornadoes, hurricanes, storms, floods, washouts and warnings for any of the foregoing which may necessitate the precautionary shut-down of wells, plants, pipelines, gathering systems, or other related facilities; arrests, orders, requests, directives, restraints and requirements of governments and government agencies and people, either federal or state, civil and military; any application of government conservation or curtailment rules and regulations; explosions, sabotage, breakage or accidents to equipment, machinery, gathering systems, plants, facilities or lines of pipe; outages (shutdown) for the making of repairs, alterations, relocations or inspections to lines of pipe, gathering systems, plants or equipment; inability to secure labor or materials, freezing of wells or lines of pipe, partial or entire failure of wells or lines of pipe, partial or entire failure of gas supply, electric power shortages, necessity for compliance with any court order, or any law, statute, ordinance, regulation or order promulgated by a Governmental Authority having or asserting jurisdiction, inclement weather that necessitates extraordinary measures and expense to construct facilities or maintain operations, or any other causes, whether of the kind enumerated herein or otherwise, not reasonably within the control of the Party claiming suspension. Such term shall likewise include, in those instances where either Party is required to obtain servitudes, rights-of-way, grants, permits, or licenses to enable such Party to fulfill its obligations hereunder, the inability of such Party to acquire, or delays on the part of such Party in acquiring, at reasonable cost and after the exercise of reasonable diligence, such servitudes, rights-of-way, grants, permits or licenses, and in those instances where either Party hereto is required to furnish materials and supplies for the purpose of constructing or maintaining facilities or is required to secure permits or permissions from any Governmental Authority to enable such Party to fulfill its obligations hereunder, the inability of such Party to acquire, or delays on the part of such Party in acquiring, at reasonable cost and after the exercise of reasonable diligence, such materials, supplies, permits, and permissions. “Force Majeure Event” also includes any event of force majeure or other interruption occurring with respect to the facilities or services of either Party’s Affiliates or third party service providers providing a service or providing any equipment, goods, supplies, or other services or items necessary to the performance of such Party’s obligations hereunder, including the occurrence of an event of force majeure event under a Third Party Gathering Agreement.

8.3 Excluded Events. “Force Majeure Event” specifically excludes the following occurrences or events: the loss, interruption, or curtailment of interruptible transportation on any Receiving Transporter necessary to take delivery of Producers’ Gas and MV Mitigation Gas at any Delivery Point, unless and only to the extent the same event also curtails firm transportation at the same Delivery Point; increases or decreases in Gas supply, allocation or reallocation of production by well operators; loss of markets; loss of supply; and failure of specific, individual wells or appurtenant facilities in the absence of a Force Majeure Event broadly affecting other wells in the same geographic area. Price changes due to market conditions with respect to the purchase or sale of Gas gathered hereunder or economics associated with the delivery, connection, receipt, gathering, compression, dehydration, treatment, processing or redelivery of Gas quantities hereunder shall not constitute Force Majeure Events. In addition, the non-availability or lack of funds or failure to pay money when due shall not constitute Force Majeure Events.

8.4 Strikes. The settlement of strikes or lockouts shall be entirely within the discretion of the Party having the difficulty, and any obligation hereunder to remedy a Force Majeure Event shall not require the settlement of strikes or lockouts by acceding to the demands of the opposing Party when such course is inadvisable in the sole discretion of the Party having the difficulty.

8.5 Notice. The Party whose performance is affected by a Force Majeure Event must provide Notice to the other Party. Initial Notice may be given orally, but written Notice with reasonably full particulars of the Force Majeure Event is required as soon as reasonably possible after the occurrence of the Force Majeure Event. The Party affected by a Force Majeure Event shall use reasonable commercial efforts to (i) remedy and (ii) mitigate the effects of the Force Majeure Event.

8.6 Force Majeure Credit. If, during the Minimum Volume Period, Producers are unable to deliver volumes of Producers’ Gas and MV Mitigation Gas to a Gathering System due to a Force Majeure Event affecting Gatherer, then the volume (expressed in Mcf’s) of Producers’ Gas and MV Mitigation Gas (the “Force Majeure Volumes”) that Producers were prevented from delivering to the affected Gathering System due to such Force Majeure Event affecting Gatherer shall be included in the determination of the Adjusted Barnett Annual Minimum Volume as provided in Section 4(d) of Exhibit A for the same Year in which such Force Majeure Event occurs. The term “Force Majeure Volumes” does not, however, include any volumes of Producers’ Gas attributable to, or that could be delivered from, Barnett Delayed Connections (including any connection with respect to which Gatherer has furnished to Producers a Pad Notice in accordance with Section 6(b)(1) of Exhibit A), which are addressed in Section 6 of Exhibit A.

8.7 Maintenance and Other Operations. Gatherer may suspend its performance hereunder to the extent required to make necessary or reasonably desirable inspections, alterations, or repairs (not required as the result of the occurrence of a Force Majeure Event) to any part of a Gathering System and to make any required relocations or modifications of pipelines and other equipment and facilities comprising part of a Gathering System. Gatherer shall give Producers reasonable Notice of its intention to suspend its performance hereunder, except in cases of emergency where such Notice is impracticable or in cases where the operations of Producers will not be affected. If, during the Minimum Volume Period, Gatherer suspends such performance with respect to any segment in excess of ** total Days in any Month (such excess Days, the “Excess Suspension Days”), then the volume (expressed in Mcf’s) of Producers’ Gas and MV Mitigation Gas (the “Maintenance Suspension Volumes”) that corresponds to the product of (i) the Excess Suspension Days multiplied by (ii) the average daily deliveries of Producers’ Gas and MV Mitigation Gas on the affected Gathering System for the 30-Day period immediately prior to the first Day in the Month in which suspension occurred (excluding any Day during such 30-Day period when no Producers’ Gas and MV Mitigation Gas is delivered to such Gathering System or the delivery of Producers’ Gas or MV Mitigation Gas to such Gathering System is affected by any maintenance downtime) but less the volumes of Producers’ Gas and MV Mitigation Gas actually received on the affected Gathering System on the Excess Suspension Day shall be included in the determination of the Adjusted Barnett Annual Minimum Volume as provided in Section 4(d) of Exhibit A for the same Year in which such suspension occurs.

(a) Restriction on Assignment. Except as provided in this Article 9, neither Party shall assign any of its rights, or delegate any of its obligations, under this Agreement (including by operation of law) without the prior written consent of the other Party, such consent not to be unreasonably withheld or delayed. For purposes of this Section 9.1, a Change of Control with respect to a Producer shall be considered an assignment of this Agreement by such Producer.

(b) Permitted Assignments. No assignment of this Agreement shall be made by Producers, except (i) to a Person that is acquiring an interest in or all or part of the Dedicated Properties contemporaneous with such assignment and (ii) with the prior written consent of Gatherer. No assignment of this Agreement shall be made by Gatherer, except (A) to a Person that is acquiring an interest in or all or a part of a Gathering System contemporaneous with such assignment and (B) with the prior written consent of Producers. Notwithstanding the foregoing, each Party may assign its rights under this Agreement to an Affiliate of such Party without the consent of the other Party and each Party may pledge this Agreement (or pledge any of its rights under this Agreement including the right to receive payments due hereunder) to secure any credit facility or indebtedness of such Party or its Affiliates without the consent of the other Party and may assign any of its rights, or delegate any of its obligations, under this Agreement to one or more of its Affiliates without the consent of the other Party; provided, no such assignment or pledge shall relieve the assignor Party from any of its obligations hereunder.

(c) Partial Assignments in Minimum Volume Period. If in connection with any permitted assignment under Section 9.1(b) that would occur during the Minimum Volume Period less than all of the Gatherer’s rights and obligations under this Agreement are proposed to be assigned, or less than all of Producers’ rights and obligations under this Agreement are proposed to be assigned, as applicable, then the Party whose consent is required shall have the right to consider and approve (in addition to other relevant matters) the manner in which redetermination of Fees, well connect obligations, natural gas minimum volume throughput commitment, maximum daily natural gas quantity limitations and similar matters are proposed to be retained by the assignor Party, to be assumed by the proposed assignee, or to be otherwise allocated among the assignor Party and the assignee.

(d) Assumed Obligations. Any permitted assignee of either Party’s rights and obligations under this Agreement shall assume and be responsible for the payment and performance of the assignor Party’s rights and obligations under this Agreement that are required to be paid or performed after the effective date of such assignment (the “Assumed Obligations”), the assignor Party shall remain liable for the obligations required to be paid and performed under this Agreement prior to the effective date of such assignment, the assignor Party shall be liable for the Assumed Obligations unless the assignor Party is released from such Assumed Obligations under Section 9.5, and the assignor Party and the permitted assignee shall be co-obligors as to the Assumed Obligations unless the assignor Party is released from such Assumed Obligations under Section 9.5.

(a) Transfer by Gatherer. If Gatherer sells, transfers, or otherwise disposes of an interest in all or any part of a Gathering System and no assignment of rights and obligations under this Agreement occurs under Section 9.1, Gatherer shall cause the acquiring Person to either (i) enter into an agreement with Producers, substantially in the form attached as Exhibit H (a “Gathering System Owner Acknowledgement Agreement”) whereby such Person acknowledges Producers’ rights to have Producers’ Gas connected to, received by, gathered, compressed, dehydrated, treated and processed, as applicable, and redelivered to Producers on and over the Gathering System in accordance with the terms of this Agreement or (ii) enter into a Separate GGA with Producers with respect to the part of the Gas Gathering System acquired by such Person. Neither the entry into a Gathering System Owner Acknowledgment Agreement or a Separate GGA shall constitute an assignment for purposes of Section 9.1.

(b) Continued Performance by Gatherer. With respect to each Gathering System Owner Acknowledgement Agreement, Gatherer shall continue to be obligated to perform its obligations under this Agreement as if the sale, transfer, or other disposition of the interest in or part of the Gathering System acquired by the Person who is a party to such Gathering System Owner Acknowledgement Agreement had not occurred.

(c) Separate GGA. With respect to each Separate GGA referenced in this Section 9.2, unless released under Section 9.5(a), (i) Gatherer shall continue to be obligated to perform and pay its obligations under this Agreement as if the sale, transfer, or other disposition of the interest in or part of the Gathering System acquired by the Person who is a party to such Separate GGA had not occurred and (ii) the performance or payment of any such obligations by the Person who is a party to such Separate GGA (or its permitted successors and assigns under the terms of such Separate GGA) shall be accepted by Producers and be considered as performed or paid by Gatherer.

(a) Transfer by Producers. If Producers or their Affiliates sell, transfer, or otherwise dispose of any of the Dedicated Properties (or any interest therein), including the sale or transfer of a production payment, overriding royalty interest, net profits interest, or other similar interest, and no assignment of rights and obligations under this Agreement occurs under Section 9.1, Producers shall cause, or shall cause their Affiliates to cause, the acquiring Person to either (i) enter into an agreement with Gatherer, substantially in the form attached as Exhibit I (a “Dedicated Properties Owner Acknowledgement Agreement”) whereby such Person acknowledges the dedication to the Gathering System of Producers’ Gas from the Dedicated Properties (or interest therein) acquired by such Person or (ii) enter into a Separate GGA with Gatherer with respect to the Dedicated Properties (or interest therein) acquired by such Person. Neither the entry into a Dedicated Properties Owner Acknowledgment Agreement or a Separate GGA shall constitute an assignment for purposes of Section 9.1.

(b) Continued Performance by Producers. With respect to each Dedicated Properties Owner Acknowledgement Agreement, Producers shall continue to be obligated to perform and pay their obligations under this Agreement as if the sale, transfer or other disposition of the Dedicated Properties (or any interest therein) acquired by the Person who is a party to such Dedicated Properties Owner Acknowledgement Agreement had not occurred.

(c) Separate GGA. With respect to each Separate GGA referenced in this Section 9.3, unless released under Section 9.5(b), (i) Producers shall continue to be obligated to perform and pay their obligations under this Agreement as if the sale, transfer or other disposition of the Dedicated Properties (or interest therein) acquired by the Person who is a party to such Separate GGA had not occurred and (ii) the performance or payment of any such obligations by the Person who is a party to such Separate GGA (or its permitted successors and assigns under the terms of such Separate GGA) shall be accepted by Gatherer and be considered as performed or paid by Producers.

(a) Completion. As to each Separate GGA relating to (i) any Barnett Gathering System to be entered into in the Minimum Volume Period, (ii) any Midcon Gathering System to be entered into prior to June 30, 2019, and (iii) any PRP Gathering System to be entered into prior to June 30, 2019, the Separate GGA will need to be completed by the insertion of the relevant information in any blanks contained in such Separate GGA. Volumes of Gas received in the Barnett Gathering Systems under a Separate GGA shall be applied to the Adjusted Barnett Annual Minimum Volume to the extent that (i) such volumes would have constituted Producers’ Gas or MV Mitigation Gas if the Barnett Dedicated Properties covered by such Separate GGA had continued to be owned by Producers or their Affiliates and (ii) the Adjusted Barnett Annual Minimum Volume has not otherwise been reduced to reflect volumes delivered under such Separate GGA.

(b) Producers Terms. If the Separate GGA is being entered into in connection with a sale, transfer or other disposition by Gatherer of part of the Gathering System, then Producers shall have the right to approve the information to be inserted in any of the blanks contained in such form, such approval not to be unreasonably withheld or delayed.

(c) Gatherer Terms. If the Separate GGA is being entered into in connection with the sale, transfer or other disposition by Producers of an interest in or part of the Dedicated Properties, then Gatherer shall have the right to approve the information to be inserted in any of the blanks contained in such form, such approval not to be unreasonably withheld or delayed.

(a) Release of Gatherer. If the assignee under an assignment consented to by Producers under Section 9.1 or the acquiring Person under a Separate GGA entered into under Section 9.2(a) has (or the guarantor of its obligations under a guaranty provided pursuant to the following sentence has) a long-term, senior unsecured credit rating equal to or greater than the Applicable Rating, then Gatherer shall be released from the Assumed Obligations applicable to such assignment or the obligations of such acquiring Person under such Separate GGA, as applicable (the “Separate GGA Gatherer Obligations”). If at the time of the assignment or the entry into the Separate GGA, as applicable, such assignee or acquiring Person does not have a long-term, senior unsecured credit rating equal to or greater than the Applicable Rating, then

such assignee or acquiring Person, as applicable, may provide to Producers a guaranty of such assignee’s/acquiring Person’s Assumed Obligations or the Separate GGA Gatherer Obligations, as applicable, from a Person with (at time of such assignment or entry into such Separate GGA) a long-term, senior unsecured credit rating equal to or greater than the Applicable Rating, which guaranty shall be in a form reasonably acceptable to Producers.

(b) Requested Gatherer Release. If in connection with any assignment or Separate GGA under Section 9.5(a) the acquiring Person does not have (and is unable to provide a guarantor with) a credit rating equal to or greater than the Applicable Rating and thus is not entitled to a release under such Section 9.5(a)(i), Gatherer may nevertheless request that Gatherer be released from the Assumed Obligations or Separate GGA Gatherer Obligations, as applicable, and in connection with each such request the financial ability of the acquiring Person (and any guarantor provided by such acquiring Person) and credit support provided by such acquiring Person or any guarantor to satisfy the Assumed Obligations or Separate GGA Gathering Obligations shall be taken into consideration and Producers shall not unreasonably withhold or delay the approval of such request.

(c) Release of Producers. If the assignee under an assignment consented to by Gatherer under Section 9.1 or the acquiring Person under a Separate GGA entered into under Section 9.3(a) has (or the guarantor of its obligations under a guaranty provided pursuant to the following sentence has) a long-term, senior unsecured credit rating equal to or greater than the Applicable Rating, then Producers shall be released from the Assumed Obligations applicable to such assignment or the obligations of such acquiring Person under such Separate GGA, as applicable (the “Separate GGA Producer Obligations”). If at the time of the assignment or the entry into the Separate GGA, as applicable, such assignee or acquiring Person does not have a long-term, senior unsecured credit rating equal to or greater than the Applicable Rating, then such assignee or acquiring Person, as applicable, may provide to Gatherer a guaranty of such assignee’s/acquiring Person’s Assumed Obligations or Separate GGA Producer Obligations under such Separate GGA, as applicable, from a Person with (at time of such assignment or entry into such Separate GGA) a long-term, senior unsecured credit rating equal to or greater than the Applicable Rating, which guaranty shall be in a form reasonably acceptable to Gatherer.

(d) Requested Producers Release. If in connection with any assignment or Separate GGA referenced in Section 9.5(c) the acquiring Person does not have (and is unable to provide a guarantor with) a credit rating equal to or greater than the Applicable Rating and thus is not entitled to a release under such Section 9.5(c), Producers may nevertheless request that Producers be released from the Assumed Obligations or Separate GGA Producer Obligations, as applicable, and in connection with each such request the financial ability of the acquiring Person (and any guarantor provided by such acquiring Person) and credit support provided by such acquiring Person or any guarantor to satisfy the Assumed Obligations or Separate GGA Producer Obligations shall be taken into consideration and Gatherer shall not unreasonably withhold or delay the approval of such request.

9.6 Inurement. Subject to this Article 9, this Agreement binds and inures to the benefit of the Parties and their respective successors and assigns.

10.1 Regulatory Bodies. This Agreement is subject to, and each Party will comply with, all Applicable Laws of any Governmental Authority now or hereafter having jurisdiction over either or both Parties or their facilities.

10.2 Additional Fees and Changes in Laws. Producers shall reimburse Gatherer for Producers’ allocable share of (a) any additional, increased, or subsequently applicable taxes (other than income taxes and any real or personal property or other ad valorem tax imposed on any Gathering System) implemented or imposed after September 30, 2009 that are lawfully levied on or paid by Gatherer with respect to its performance under this Agreement or on any part of a Gathering System and (b) any new or subsequently applicable assessments, fees or other charges implemented or imposed on Gatherer with respect to the services provided hereunder, including any such assessments, fees or other charges arising from any carbon tax or cap and trade law, rule or regulation adopted after September 30, 2009. Producers’ allocable share of any such amounts shall be based on the ratio that Producers’ Gas and MV Mitigation Gas (each expressed in Mcf’s) received at the Receipt Points in the State or States in which such amounts are imposed bears to the total volume of Gas (expressed in Mcf’s) received at such Receipt Points, in each case during the applicable period for which such taxes, assessments, fees or other charges are incurred or imposed, as the case, may be. To the extent that any of Gatherer’s activities pursuant to this Agreement produce or result in the generation of or otherwise qualify for any emission reduction credits or emission offset credits or bonus emission allowances (collectively, “Greenhouse Gas Credits”) and Producers have paid for an allocable share of the costs of such activities pursuant to this Section 10.2, then Producers shall be entitled to receive, and Gatherers shall obtain and convey to Producers, their allocable share of any such Greenhouse Gas Credits. If any Governmental Authority takes any action (including issuance of any “policy statement,” rule, or regulation) whereby the receipt, gathering, treating, or delivery of Producers’ Gas and MV Mitigation Gas as contemplated under this Agreement shall be prohibited or subject to terms, conditions or regulations, including rate or price controls or ceilings or open access requirements not in effect on September 30, 2009 and which, in the reasonable judgment of Gatherer, materially adversely affect the economics of the services provided, and Fees received, under this Agreement, then, upon Notice by Gatherer to Producers, the Parties shall as promptly as practicable meet to negotiate in good faith such changes to the terms of this Agreement as may be necessary or appropriate to preserve and continue for the Parties the rights and benefits originally contemplated for the Parties by this Agreement, including the returns expected by Gatherer, with such amendment to this Agreement to be effective no later than the effective date of such new or amended Applicable Law.

11.1 Agency. For all purposes of this Agreement, Producers individually and collectively irrevocably appoint CEMI as their agent to receive and make all notices, invoices, payments and other communications under this Agreement from or applicable to Producers and to make, withhold, grant and take all approvals, consents, decisions, and actions required or permitted of Producers under or in connection with this Agreement.

12.11 Confidentiality. Neither Party shall disclose, directly or indirectly, without the prior written consent of the other Party the terms of this Agreement to a third party (other than Affiliates, employees, lenders, royalty owners, co-working interest owners, counsel, accountants, and agents of the Party, or a prospective or permitted assignee under Article 9 or prospective or actual purchaser of an interest in any Gathering System or in any of the Dedicated Properties, provided such Persons shall have agreed to keep such terms confidential), except (i) to comply with any Applicable Law or exchange rule, (ii) to the extent necessary for the enforcement of this Agreement, or (iii) to the extent necessary to comply with a regulatory agency’s reporting requirements. Each Party shall notify the other Party of any proceeding of which it is aware which may result in disclosure of the terms of this Agreement (other than as permitted hereunder) and use reasonable efforts to prevent or limit the disclosure. The existence of this Agreement is not subject to this confidentiality obligation. The entry into, or filing of a memorandum in the applicable public records with respect to this Agreement, a Separate GGA, a Dedicated Properties Owner Acknowledgment Agreement, or a Gathering System Owner Acknowledgment Agreement shall not constitute a breach of this Section 12.11. The Parties shall be entitled to all remedies available at law or in equity to enforce, or seek relief in connection with this confidentiality obligation. The terms of this Agreement shall be kept confidential by the Parties for one Year from the expiration or termination of this Agreement. If disclosure is required by a Governmental Authority or Applicable Law, the Party subject to such requirement may disclose the material terms of this Agreement to the extent so required, but shall promptly notify the other Party, prior to disclosure, and shall cooperate (consistent with the disclosing Party’s legal obligations) with the other Party’s efforts to obtain protective orders or similar restraints with respect to such disclosure at the expense of the other Party.

(a) Surface Rights. Oil and gas leases, oil and gas rights derived under farmout agreements, surface damage releases, right of way agreements, pooling orders and similar agreements and rights held by Producers covering the Barnett Dedicated Properties (collectively referred to herein as an “Oil and Gas Lease”) may permit Producers to lay gathering pipelines and related facilities for the purpose of moving natural gas and crude oil from any well producing from the oil, gas and mineral estate covered by such Oil and Gas Lease or lands pooled or unitized with such Oil and Gas Lease. The surface of the land covered by an Oil and Gas Lease is referred to herein as the “Surface Estate” and the owner of such Surface Estate is referred to herein as a “Surface Estate Owner.”

(b) Cooperation. With respect to any easements/rights of way across Surface Estates needed by Gatherer to connect the Gathering System to existing or future wells producing from the oil, gas and mineral estate covered by the related Oil and Gas Lease or lands pooled or unitized with such Oil and Gas Lease (a “Subject Well”), Gatherer shall first attempt to obtain such easements/right of ways from the Surface Estate Owners. If Gatherer is unable to obtain any such easement/right of way from a Surface Estate Owner, Gatherer may notify the Producers thereof and request that the Producer holding the related Oil and Gas Lease reasonably cooperate with Gatherer in attempting to obtain the needed easement/right of way and such Producer shall so reasonably cooperate with Gatherer. The aforesaid obligation of Producer to reasonably cooperate with Gatherer shall not require Producer to pay any consideration to a Surface Estate Owner unless there is a contemporaneous reimbursement by Gatherer.

(c) Partial Assignment. If the needed easement/right of way has not been obtained after such cooperative efforts or Gatherer in good faith believes that such efforts will not be successful, Gatherer may request that the applicable Producer execute and deliver to Gatherer an assignment in the form of Exhibit L (a “Oil and Gas Lease Partial Assignment”). Provided that the applicable Oil and Gas Lease permits the assignment contemplated by the form attached as Exhibit L and (if applicable) any required consent from the other party to the Oil and Gas Lease is obtained, Gatherer and the applicable Producer shall cooperate in completing such form by inserting or attaching a description of the applicable Oil and Gas Lease, Subject Well and Surface Estate, Gatherer and Producer shall execute such completed Oil and Gas Lease Partial Assignment, and Producer shall have the right to record such Oil and Gas Lease Partial Assignment in the applicable public records. Gatherer shall not be required to pay any separate consideration to Producers for any such Oil and Gas Lease Partial Assignment. As reflected in the form attached as Exhibit L, Gatherer’s use of the Surface Estate covered by each Oil and Gas Lease Partial Assignment shall be subject to the terms of the related Oil and Gas Lease.

(d) Removal. As between Gatherer and Producers, any property of Gatherer placed in, on or under any such Surface Estate pursuant to an Oil and Gas Lease Partial Assignment shall remain the property of Gatherer, subject to removal by Gatherer (at its expense) when necessary or desirable (as determined by Gatherer in its sole and reasonable judgment provided that such removal shall not result in Gatherer being in breach of its other obligations under this Agreement). Gatherer shall have a reasonable time after the expiration or termination of this Agreement to remove its property placed on, in or under a Surface Estate under any such Oil and Gas Lease Partial Assignment. If under the terms of the Oil and Gas Lease applicable to any Oil and Gas Lease Partial Assignment the property placed in, on or under the Surface Estate by Gatherer is required to be removed upon the expiration or termination of such Oil and Gas Lease,

then Gatherer shall be obligated to effect such removal (at its expense) in a manner consistent with the terms of such Oil and Gas Lease and any applicable regulations. The obligations of Gatherer under this Section 12.12 shall survive the expiration or termination of this Agreement.

12.13 Cooperation Meetings. As frequently as necessary, CEMI, on behalf of Producers, and Gatherer shall meet at a mutually agreeable location to discuss and review Producers’ drilling and other development plans on the Dedicated Properties, Gatherer’s expansion plans for the Gathering Systems, and any other information regarding Producers’ and Gatherer’s operations that may be appropriate or helpful to the Parties performance under this Agreement.

(a) Agency. CELLC hereby designates Gatherer as its lawful agent to design, construct, operate, maintain and repair the DFW Gathering System and to discharge all business, accounting, legal and regulatory matters related to the DFW Gathering System as the agent for CELLC (the “O&M Activities”) until the DFW O&M Terms become effective as provided below. Gatherer hereby accepts such designation. Gatherer shall be responsible for all costs incurred in connection with O&M Activities conducted by Gatherer, its Affiliates and other Persons engaged by Gatherer or its Affiliates to perform O&M Activities. In compensation for paying the costs of such O&M Activities, Gatherer shall receive all revenues derived from the operation of the DFW Gathering System during the term of this designation, including the applicable Barnett Fees paid for all volumes of Producers’ Gas and MV Mitigation Gas delivered to the DFW Gathering System during the term of this designation. The designation hereunder shall terminate on the date the DFW O&M Terms become effective below.

(b) DFW O&M Terms. During the period between the Effective Date of this Agreement and February 12, 2010, the Parties will negotiate in good faith, execute, and deliver an addendum to this Agreement covering the operation and maintenance of the DFW Gathering System (the “DFW O&M Terms”). The DFW O&M Terms will contain the following terms and other terms as may be reasonable for an operation and maintenance agreement of this type:

(i) Gatherer shall operate and maintain the DFW Gathering System in substantially the same manner as Gatherer operates and maintains the other Barnett Gathering Systems and Gatherer shall exercise commercially reasonable efforts to operate the DFW Gathering System in compliance with the Oil and Gas Lease dated October 4, 2006 among Dallas/Fort Worth International Airport Board, City of Dallas, City of Fort Worth (collectively, “Airport Board”) and CELLC (the “DFW Lease”) and the Pipeline License executed on June 11, 2007 and June 12, 2007 by and between Dallas/Fort Worth International Airport Board and CELLC (the “DFW License”).

(ii) Gatherer will receive as a fee for its services for all Gas gathered from wells connected to the DFW Gathering System an amount equal to all revenues derived from operation of the DFW Gathering System during the term of the DFW O&M Terms, including the applicable Barnett Fees paid to Gatherer pursuant to this Agreement during the term of the DFW O&M Terms.

(iii) The DFW O&M Terms will be coterminous with this Agreement, subject to early termination as provided below.

(iv) Producers will indemnify and defend Gatherer (and its successors and assigns) from and against any and all liabilities, losses, costs and expenses associated with the operation of the DFW Gathering System and not typically assumed by an operator of assets similar to the DFW Gathering System, including all such liabilities, losses, costs, and expenses related to abandonment, restoration, and clean-up obligations associated with all or any portion of the DFW Gathering System and any loss, cost, liability or obligation arising from or relating to any requirement that may be imposed to relocate all or any portion of the DFW Gathering System.

(v) Gatherer will indemnify and defend Producers (and their respective successors and assigns) from and against any and all liabilities, losses, costs and expenses related to or arising from any breach by Gatherer of the DFW O&M Terms.

(vi) Gatherer’s prior written consent, which consent shall not be unreasonably withheld, shall be required to any changes to the DFW Lease or DFW License that would affect Gatherer’s rights or obligations under the DFW O&M Terms.

(vii) Gatherer will be an independent contractor and not an agent or partner of Producers or its Affiliates.

(viii) The O&M Terms will include rights of the Producers to terminate the DFW O&M Terms if any party other than CELLC (or its Affiliates) alleges a material breach of the DFW Lease or DFW License as a result of Gatherer’s operations hereunder and Gatherer shall have a right to terminate the DFW O&M Terms upon a termination of the DFW Lease or the DFW License. Upon any such termination, Producers would make a termination payment to Gatherer that equals the economic benefits that the Gatherer would have received if the DFW O&M Terms had not been so terminated and Producers shall indemnify Gatherer from any other losses arising from such early termination. If Producers make such termination payment, **% of the DFW PDP Volumes remaining to be delivered as of the date of such termination shall be included in the determination of the Adjusted Barnett Annual Minimum Volume as provided in Section 4(d) of Exhibit A for the same Year. “DFW PDP Volumes” means the proved developed producing volumes of Producers’ Gas to be delivered to DFW Gathering System determined as of the Effective Date.

(c) DFW License Termination. Producers may terminate this agency if any party other than CELLC (or its Affiliates) alleges a material breach of the DFW Lease or DFW License as a result of Gatherer’s operations hereunder and Gatherer shall have a right to terminate this agency upon a termination of the DFW Lease or the DFW License. Upon any termination of the DFW Lease or DFW License, Producers shall make a termination payment to Gatherer that equals the economic benefits that the Gatherer would have received if this agency had not

terminated and Producers shall indemnify Gatherer from any other losses arising from such early termination. If Producers make such termination payment, the DFW PDP Volumes remaining to be delivered as of the date of such termination shall be included in the determination of the Adjusted Barnett Annual Minimum Volume as provided in Section 4(d) of Exhibit A for the same Year.

(d) Agency Termination. CELLC represents to Gatherer that the Agency Agreement, dated August 1, 2008, among CELLC, Chesapeake Operating, Inc., and Chesapeake Midstream Operating, L.L.C. has been terminated and is of no further force or effect.

(e) Indemnity. Producers shall indemnify, defend, and hold harmless Gatherer from all Claims asserted by the Airport Board against Gatherer arising from Producers entry into the arrangements contemplated hereunder.

(f) Definition. “DFW Gathering System” means the gathering system described as the “DFW Gathering System” in Schedule A1 as it exists on the Effective Date.

12.15 Amendment. This Agreement may be amended, supplemented or modified only by a written instrument duly executed by or on behalf of Gatherer and Producers.

12.16 Amended and Restated Agreement. Effective as of February 1, 2010, this Agreement amends and restates in its entirety the Gas Gathering Agreement between Producers and Gatherer dated September 30, 2009. Except as provided in this Section 12.16, the terms and provisions of such original Gas Gathering Agreement (as they existed prior to the amendment and restatement of such terms and provisions herein) shall continue to apply (without modification) as to all matters required to be paid or performed by the Parties under this Agreement as to periods prior to February 1, 2010. The Parties acknowledge and agree that the volumes shown for Year 2010 in Schedule A7 (the second Year of the Minimum Volume Period) include the deficit volumes required under Section 4(b) of Exhibit A to be carried forward to Year 2010 from Year 2009 and added to the Adjusted Barnett Annual Minimum Volume for Year 2010. Producers also acknowledge and agree that they remain liable to pay Gatherer for the shortfall volume for Year 2009 that occurred in excess of such deficit volumes carried forward to Year 2010.

IN WITNESS WHEREOF, the Parties have executed this Agreement as of the Effective Date.

The following terms and conditions shall apply to the gathering of Producers’ Gas and (where applicable) MV Mitigation Gas on the Barnett Gathering Systems.

(a) Producers’ Commitment. Subject only to Producers’ Barnett Reservations, Producers exclusively dedicate and commit to the performance of this Agreement the Barnett Dedicated Properties, represent that the Barnett Dedicated Properties are not otherwise subject to any other gas gathering agreement or other commitment or arrangement that would permit or require Producers’ Gas from the Barnett Dedicated Properties to be gathered on any other gas gathering system, and agree not to deliver any Gas produced from the Barnett Dedicated Properties and owned or controlled by Producers or their Affiliates to any other gas gatherer, gas purchaser, gas marketer, or other Person prior to the Barnett Delivery Points. Producers agree to cause any existing or future Affiliates of Producers to be bound by, and to execute and join as a party, this Agreement. The dedication and commitment made by Producers and their Affiliates under this Agreement is a covenant running with the land.

(b) Producers’ Reservations. Producers reserve the following rights (“Producers’ Barnett Reservations”): (i) to operate wells producing from the Barnett Dedicated Properties as a reasonably prudent operator, (ii) to separate or process Gas prior to delivery at the Barnett Receipt Points so long as such Producers’ Gas and MV Mitigation Gas meets the gas specifications herein after such separation or processing, (iii) to use Gas produced from the Barnett Dedicated Properties for lease operations, and (iv) to pool, communitize, or unitize Producers’ interests in the Barnett Dedicated Properties.

(c) Transfer of Producers’ Interests. Any transfer by Producers or their Affiliates of any of their interests in the Barnett Dedicated Properties shall comply with Article 9 of this Agreement.

(d) Memorandum. Producers shall enter into and deliver to Gatherer, at Gatherer’s request, a fully recordable memorandum of this Agreement, substantially in the form of Exhibit M.

(a) Gathering and Compression Fees. As consideration for receiving Producers’ Gas or MV Mitigation Gas at each Barnett Receipt Point each Month, Producers shall pay Gatherer each Month an amount equal to the applicable Barnett Fees (expressed in $/Mcf) for each Barnett Receipt Point shown in Schedule A2 (as supplemented from time to time) applied to the volume of Producers’ Gas and MV Mitigation Gas (net of gas lift volumes) received at each such Barnett Receipt Point during such Month. In addition to payment of such amounts, Producers shall reimburse Gatherer each Month for Producers’ allocated share of Electric Power Charges on each Barnett Gathering System and any other Barnett Fees shown in Schedule A2, in each case based on the volume of Producers’ Gas and MV Mitigation Gas (net of gas lift volumes) received at each such Barnett Receipt Point during such Month.

(b) Dehydration Service Fees. Producers’ Gas and MV Mitigation Gas delivered to the Barnett Receipt Points may have a water vapor content that exceeds the quality specification for water vapor content permitted from time to time by one or more of the Barnett Receiving Transporters. In such event, Gatherer will dehydrate, if necessary, Producers’ Gas or MV Mitigation Gas to reduce its water vapor content to 7 pounds per million Cubic Feet. The fee for such dehydration services is included in the Barnett Fees. In addition to the Barnett Fees, Gatherer will charge Producer for, or retain Gas in connection with, as applicable, Producers’ allocable share of Fuel Gas and Lost and Unaccounted for Gas incurred in connection with dehydration services performed under this Section 2(b). Gatherer shall be responsible for the costs incurred in disposing of water removed from Producers’ Gas or MV Mitigation Gas during dehydration. If the quality specification for water content is reduced below 7 pounds per million Cubic Feet by one or more of the Barnett Receiving Transporters, then the Parties shall promptly negotiate an additional fee (that includes Gatherer’s cost of capital) to be paid by Producers to reimburse Gatherer for the cost of additional dehydration services to comply with such specifications.

(c) Treating Service Fees. Producers’ Gas or MV Mitigation Gas delivered to the Barnett Receipt Points may have carbon dioxide or hydrogen sulfide content that exceeds the quality specification for carbon dioxide or hydrogen sulfide content required from time to time by one or more of the Barnett Receiving Transporters. In such event, without limiting Gatherer’s rights under Section 10(c) of this Exhibit A, Gatherer will treat, if necessary, Producers’ Gas or MV Mitigation Gas to reduce the carbon dioxide content to 2% and hydrogen sulfide to not more than 1/4 grain of hydrogen sulfide per 100 Cubic Feet of Gas. The fee for Gatherer providing such treating services is included in the Barnett Fees to the extent such services are provided by Gatherer with facilities comprising part of a Barnett Gathering System on September 30, 2009. If additional facilities are required to provide such treating services or if the quality specification for carbon dioxide or hydrogen sulfide of the Barnett Receiving Transporters is reduced below 2% and 1/4 grain of hydrogen sulfide per 100 Cubic Feet of Gas, then Parties shall promptly negotiate an additional fee (that includes Gatherer’s cost of capital) to be paid by Producers to Gatherer to provide such additional treating services. If the Parties are unable to agree upon an additional fee, then Gatherer may refuse to accept receipt of such Producers’ Gas or MV Mitigation Gas for delivery to such Barnett Receiving Transporter. Gatherers’ right to negotiate additional treating fees or right to refuse further deliveries of such Producers’ Gas or MV Mitigation Gas shall apply to each additional reduction in quality specification for carbon dioxide or hydrogen sulfide content of the Barnett Receiving Transporters. In addition to the fees referred to above, Gatherer will charge Producer for, or retain Gas in connection with, as applicable, Producers’ allocable share of Fuel Gas and Lost and Unaccounted for Gas incurred in connection with treating services performed in accordance with this Section 2(c). If Gatherer removes carbon dioxide from Producers’ Gas or MV Mitigation Gas gathered on any Barnett Gathering System, Producers shall have the right (but not the obligation) to keep title to and retain all such carbon dioxide removed from Producers’ Gas or MV Mitigation Gas. If Producers so elect to retain title to such carbon dioxide, then Producers shall be responsible (at their sole risk, cost and expense) to arrange for the taking and delivery of such carbon dioxide at and from each point on the Barnett Gathering System where such carbon dioxide is so removed, and Gatherer shall make such carbon dioxide available for taking at prevailing pressures after treating. Notwithstanding the foregoing, nothing in this Section 2.3(c) shall require Gatherer to install facilities or incur any capital expense associated with such delivery.

(a) First Barnett Redetermination Notice. Either Producers or Gatherer may, at any time during the six-month period commencing at 7:00 a.m. (CPT) on September 30, 2011, provide Notice to the other Party of its desire to redetermine all or any portion of the Barnett Fees (the “First Barnett Redetermination Notice”). Upon receipt by Producers or Gatherer of the First Barnett Redetermination Notice, the Parties shall, as promptly thereafter as is commercially practicable, enter into discussions and negotiations regarding whether all or any portion of the Barnett Fees should be adjusted, which discussions and negotiations shall take into account (in addition to other relevant items) the factors specified below in Section 3(c) of this Exhibit A.

(b) Second Barnett Redetermination Notice. At any time during the two-year period commencing at 7:00 a.m. (CPT) on September 30, 2014, either Producers or Gatherer may give the Second Barnett Redetermination Notice. The Party that elects to give the Second Barnett Redetermination Notice shall provide Notice to the other Party of its desire to redetermine all or any portion of the Barnett Fees (the “Second Barnett Redetermination Notice”). Upon receipt by the other Party of the Second Barnett Redetermination Notice, the Parties shall as promptly thereafter as is commercially practicable enter into discussions and negotiations regarding whether all or any portion of the Barnett Fees should be adjusted, which discussions and negotiations shall take into account (in addition to other relevant items) the factors specified below in Section 3(c) of this Exhibit A.

(c) Factors for Redetermination. Gatherer and Producers acknowledge that the following are the principal purposes for the inclusion by the Parties of the right to redetermine and adjust the Barnett Fees under this Section 3 of Exhibit A: (i) to mitigate the high degree of uncertainty in forecasting (A) future capital expenditures (including capital expenditures related to rights-of-way, construction labor, maintenance, connections to or expansions or extensions of, or pipeline integrity costs of the Barnett Gathering Systems) (hereinafter referred to as “Barnett Cap Ex”), (B) future compression expenses (whether capitalized or expensed) (including costs associated with rentals payments, standby fees, mobilization and demobilization, facility construction, environmental testing, pollution control equipment, emissions control equipment, permitting, acquisition of emissions allowances, maintenance, overhauls, and electricity facilities such as power lines and substations, but excluding electricity costs) (hereinafter referred to as “Barnett Compression Expense”), (C) the impact (positive or negative) on revenues realized by Gatherer related to Producers’ Gas and MV Mitigation Gas from varying Barnett Fees (including varying fee-tiers that result from changes in pressure at the Barnett Receipt Points or from changes in the Gas volume mix across Barnett Gathering Systems that have varying system fees) and (D) the impact on the timing of revenues realized by Gatherer as a result of shifts or accelerations in the Barnett Annual Minimum Volume commitment resulting from delays in completion of connections, Force Majeure or maintenance activities within the targeted time periods in accordance with this Exhibit A, and (ii) to assure that the Barnett Fees permit the Gatherer to achieve an acceptable return (expressed in terms of the unlevered, pre-income tax IRR to Gatherer) over the Minimum Volume Period on the actual and projected increased or decreased cash flow as compared to cash flows forecasted as of the date of this Agreement as set forth on Schedule A8. Upon receipt by Producers or Gatherer of the First Barnett Redetermination Notice or the Second Barnett Redetermination Notice, the Parties shall as promptly thereafter as is commercially practicable enter into discussions and negotiations to

determine whether the Barnett Fees should be adjusted, which discussions and negotiations shall take into account (in addition to other relevant items) that Producers and Gatherer intend that the net present value, discounted (to July 1, 2009) at an unlevered, pre-income tax rate of **% (“Target IRR”), of the “Annual Net Cash Flow Difference” shall be equal to zero (0), where the “Annual Net Cash Flow Difference” is (i) for each Year (or portion thereof) in the Minimum Volume Period, the sum of the following: (A) the Total Cap Ex Difference (as defined below), (B) Estimated Cap Ex Ad Valorem Tax Change (as defined below), (C) Applicable Barnett Revenues Differential (as defined below), (D) the Barnett Compression Expense Difference (as defined below), and (E) the Increased (or Decreased) Revenues from the Barnett Fee Adjustment (as defined below), and (ii) as of the first Year after the Minimum Volume Period the Terminal Value (as defined below). For purposes of this Section 3(c), the first Year shall be deemed to have commenced on July 1, 2009 (as if this Agreement were in effect on such date and as if the Minimum Volume Period started on such date). For purposes of adjusting the Barnett Fees pursuant to this Section 3(c), the Producers and Gatherer shall determine and take into account (in addition to other relevant factors) the following:

(i) the amount of the Barnett Cap Ex projected as of September 30, 2009 to be incurred from and after July 1, 2009 for each Year (or portion thereof) of the Minimum Volume Period in respect of the Barnett Gathering Systems (the “Original Barnett Cap Ex Projections”) as set forth in the first line under “Capital Expenditures and Ad Valorem” in Schedule A8;

(ii) the amount of Barnett Cap Ex actually expended by Gatherer for each Year (or portion thereof) prior to the date of determination, excluding any capital required to be excluded in accordance with Section 3(g) below (the “Actual Barnett Cap Ex”);

(iii) the amount of Barnett Cap Ex projected to be expended by Gatherer for each Year (or portion thereof) during the remainder of the Minimum Volume Period as such projected amounts are adjusted based on the specific factors then affecting actual capital expenditures and excluding projected capital expenditure amounts required to be excluded in accordance with Section 3(g) below (the “Revised Projected Barnett Cap Ex”);

(iv) for each Year (or portion thereof) of the Minimum Volume Period, the difference (expressed as a positive or negative number, as applicable) between (A) the amount for such Year (or portion thereof) specified in the Original Barnett Cap Ex Projections and (B) (I) the Actual Barnett Cap Ex for such Year (or portion thereof) and (II) for each Year (or portion thereof) during the remainder of the Minimum Volume Period, the Revised Projected Barnett Cap Ex (the difference for each Year (or portion thereof) of the Minimum Volume Period, the “Total Cap Ex Difference”);

(v) the estimated incremental or reduced ad valorem taxes for each Year (or portion thereof) of the Minimum Volume Period and for the Year thereafter resulting from the Total Cap Ex Difference, such estimate to be calculated in accordance with the methodology specified in footnote (4) of Schedule A8 (such estimated incremental or reduced ad valorem taxes, the “Estimated Cap Ex Ad Valorem Tax Change”);

(vi) the amount of the Barnett Compression Expense projected as of September 30, 2009 to be incurred from and after July 1, 2009 for each Year (or portion thereof) of the

Minimum Volume Period in respect of the Barnett Gathering Systems (the “Original Barnett Compression Projections”) as set forth in the first line under “Barnett Compression Expense” in Schedule A8;

(vii) the amount of Barnett Compression Expense actually expended by Gatherer for each Year (or portion thereof) prior to the date of determination, excluding any compression expense required to be excluded in accordance with Section 3(g) below (the “Actual Barnett Compression Expense”);

(viii) the amount of Barnett Compression Expense projected to be expended by Gatherer for each Year (or portion thereof) during the remainder of the Minimum Volume Period and for the Year thereafter as such projected amounts are adjusted based on the specific factors then affecting actual expenditures (including Gas volumes, pressure requirements, horsepower requirements, permitting costs, emissions costs, rental payments, maintenance costs, overhaul costs, and other factors) and excluding projected compression expense amounts required to be excluded in accordance with Section 3(g) below (the “Revised Projected Barnett Compression Expense”);

(ix) for each Year (or portion thereof) of the Minimum Volume Period and for the Year thereafter, the difference (expressed as a positive or negative number, as applicable) between (A) the amount for such Year (or portion thereof) specified in the Original Barnett Compression Projections and (B) (I) the Actual Barnett Compression Expense for such Year (or portion thereof) and (II) for each Year (or portion thereof) during the remainder of the Minimum Volume Period, the Revised Projected Barnett Compression Expense (the difference for each Year (or portion thereof) of the Minimum Volume Period, the “Barnett Compression Expense Difference”);

(x) the revenues projected as of September 30, 2009 to be received by Gatherer from and after July 1, 2009 (“Original Barnett Revenue Projections”) from Producers’ Gas in respect of the Barnett Gathering Systems for each Year (or portion thereof) during the Minimum Volume Period as specified in the first line item under “Revenues from Producers” in Schedule A8;

(xi) the actual revenues realized by Gatherer for each Year (or portion thereof) to the date of determination from Producers’ Gas and MV Mitigation Gas in respect of the Barnett Gathering Systems and excluding projected revenue amounts required to be excluded in accordance with Section 3(g) below (the revenues for each such Year (or portion thereof), the “Actual Barnett Revenues”);

(xii) the volumes of Producers’ Gas and MV Mitigation Gas projected to be received at the Barnett Receipt Points during each Year (or portion thereof) of the remainder of the Minimum Volume Period and for the Year thereafter, as such projected amounts are further adjusted by the specific factors then affecting actual realizations, utilizing updated forecasts of future drilling (the “Revised Projected Barnett Volumes”), and the net revenues projected to be realized for each Year of the remainder of the Minimum Volume Period from the Revised Projected Barnett Volumes for such Year, utilizing the Barnett Fees for such Year determined in accordance with Schedule A2 and excluding projected revenue amounts required to be excluded in accordance with Section 3(g) below (such net revenues, the “Revised Projected Barnett Revenues”);

(xiii) for each Year (or portion thereof) of the Minimum Volume Period, the difference (expressed as a positive or negative number, as applicable) between (A) (I) the Actual Barnett Revenues for such Year (or portion thereof) with respect to the period preceding the date of determination and (II) with respect to the remainder of the Minimum Volume Period, the Revised Projected Barnett Revenues for each Year (or portion thereof) in the remainder of the Minimum Volume Period, and (B) the Original Barnett Revenue Projections for such Year (or portion thereof) (the amount for each Year calculated in accordance with this clause (ix) of Section 3(c), the “Applicable Barnett Revenues Differential”);

(xiv) for each Year (or portion thereof) of the remainder of the Minimum Volume Period the increase (or decrease) in revenues projected to be received in respect of the Revised Projected Barnett Volumes for such Year and the Barnett Fee Adjustment (as defined below) (the “Increased (or Decreased) Revenues from the Barnett Fee Adjustment”) determined in accordance with this Section 3(c); and

(xv) the terminal value (the “Terminal Value”), such Terminal Value to be calculated as the product of (A) ** (the “Terminal Value Multiple”) and (B) the Increased (or Decreased) Revenues from the Barnett Fee Adjustment for the first Year after the Minimum Volume Period (calculated as illustrated under the caption “Barnett Fee Adjustment Required to Achieve Target IRR” in Schedule A8) plus the Estimated Cap Ex Ad Valorem Tax Change and the Barnett Compression Expense Difference for the first Year after the Minimum Volume Period.

Taking into account the factors described in items (i) through (xv)) above, the fee adjustment (the “Barnett Fee Adjustment;” to be expressed in $ per Mcf), if any, to the Barnett Fees proposed to be made in response to the First Barnett Redetermination Notice or Second Barnett Redetermination Notice, as the case may be (which adjusted Barnett Fees, if any, will be effective as specified in Section 3(f) of this Exhibit A), shall be such that the net present value, discounted (to July 1, 2009) at the Target IRR, of the Annual Net Cash Flow Difference is equal to zero (0), with the Annual Net Cash Flow Difference to be calculated based on a determination of Increased (or Decreased) Revenues from the Barnett Fee Adjustment for each Year in the remainder of Minimum Volume Period and for the Year thereafter using such Barnett Fee Adjustment escalated as contemplated pursuant to the fourth sentence of this paragraph. In making any determination with respect to whether the Barnett Fees should be adjusted under this Section 3(c), any reduction or increase in operating or general and administrative expenses (excluding Barnett Compression Expense) shall be disregarded for purposes of such model determination. Any Barnett Fee Adjustment made under this Section 3(c) of Exhibit A may be an increase or decrease in the applicable Barnett Fees; provided, however, that the cumulative upward or downward Barnett Fee Adjustments made under this Section 3(c) of Exhibit A in respect of the First Barnett Redemption Notice and Second Barnett Redemption Notice shall not exceed 27.5% of $** per Mcf subject to escalation in accordance with Schedule A2 (such limitation the “Barnett Redetermination Cap”). The Barnett Fee Adjustment will be allocated among the various annually escalated Barnett Fees set forth on Schedule A2 in order (i) to increase or decrease (as applicable) the Barnett Fees in each pressure tier specified in Schedule A2

such that the projected volume weighted average Barnett Fees charged for Producers Gas and MV Mitigation Gas that follows such redetermination are adjusted by the Barnett Fee Adjustment, subject to the Barnett Redetermination Cap for the Year of redetermination, and (ii) subject to conformity with clause (i) of this sentence, to preserve as closely as possible the differences in Barnett Fees between the specified Receipt Point pressure fee tiers set forth in Schedule A2 (as escalated in accordance with Schedule A2) The Barnett Fees as adjusted by any Barnett Fee Adjustment determined in accordance with this Section 3(c) shall be escalated after the date of determination of the Barnett Fee Adjustment in accordance with Schedule A2. Schedule A8 sets forth an illustrative example of the Barnett Fee Redetermination methodology assuming the redetermination is as of January 1, 2012.

(d) Industry Expert. If, within 30 Days after the other Party’s receipt of the First Barnett Redetermination Notice or Second Barnett Redetermination Notice, as applicable, the Parties have not entered into an amendment to this Agreement reflecting the Parties’ agreement regarding adjustments to the Barnett Fees, then either Party may notify the other of its request to have an Industry Expert determine adjustments to all or any portion of the Barnett Fees (the Party to give such a notice, the “Notifying Party”, and the recipient of such a notice, the “Receiving Party”). Upon the receipt of such a request for an Industry Expert determination from the Notifying Party, the Notifying Party and Receiving Party shall confer in good faith for up to 5 Business Days to agree on the selection of an Industry Expert to determine if, taking into account the factors enumerated above in Section 3(c) of this Exhibit A, an adjustment to the Barnett Fees is appropriate. If the Parties are unable to agree upon the selection of an Industry Expert within such 5 Business Day period, then each of the Notifying Party and Receiving Party will select an Industry Expert and the two firms so selected will select a Person to serve as the Industry Expert. Following such selection of an Industry Expert, each Party shall present to the Industry Expert a written statement of its position on proposed adjustments to the Barnett Fees (including its methodology for calculating such adjustments) not later than 30 Days after the selection of such Industry Expert. The Industry Expert may, within 30 Days after its receipt of such statements, request such additional information from either or both Parties as the Industry Expert may deem reasonably necessary or desirable for purposes of making its determination. Each Party agrees to promptly provide the Industry Expert with all information so requested of it. The Industry Expert shall make its determination in a manner consistent with Section 3(c) of this Exhibit A above and Schedule A8. The Industry Expert shall be instructed to determine and submit to the Parties its decision regarding adjustments to all or any portion of the Barnett Fees; provided, however, that any increase or decrease to any Fee determined by the Industry Expert shall be subject to the Barnett Redetermination Cap. The decision of the Industry Expert shall be conclusive, binding upon, and non-appealable by the Parties; provided that, the decision of the Industry Expert shall not be binding on the Gatherer unless and until it has received an opinion from its counsel that such Fees as proposed to be adjusted will be treated as qualifying income (as defined in Section 7704(d) of the Internal Revenue Code of 1986, as amended). In making a determination under this Section 3(d) of Exhibit A, an Industry Expert shall be authorized to engage such independent consultants, which may include an independent reservoir engineering firm or engineering firm that is a recognized leader in advising midstream companies on the design and estimated construction costs of gathering systems in the Barnett region, provided that each of such consultants must not have a material conflict of interest in relation to Producers and CHK Parent, on the one hand, or Gatherer or its members, on the other hand. The costs and expenses of the Industry Expert and such other consultants shall be shared equally by the Parties.

(f) Effect of Redetermined Fee. Any Barnett Fees redetermined under this Section 3 of Exhibit A shall apply as of the first day of the Month following the date on which such redetermined Barnett Fees are finally determined, and shall remain in effect for the remainder of the Primary Term (or, if such redetermined Barnett Fee relates to the First Barnett Redetermination Notice, until the Barnett Fees are redetermined under the Second Barnett Redetermination Notice, if any, which redetermined Barnett Fees shall remain in effect for the then remainder of the Primary Term).

(g) Excluded Cap Ex, Revenues and Compression Expense. The amount of Actual Barnett Cap Ex, Revised Projected Barnett Cap Ex, Actual Barnett Compression Expense and Revised Projected Barnett Compression Expense determined in accordance with this Section 3 shall exclude any capital expended (in the case of the Actual Barnett Cap Ex determination), costs paid (in the case of the Actual Barnett Compression Expense) or projected to be expended (in the case of the Revised Projected Barnett Cap Ex and Revised Projected Barnett Compression Expense) for additional facilities in accordance with Section 2(b), Section 2(c), Section 5(a), Section 5(b)(2), Section 6(c), Section 6(d), Section 6(f), or Section 13 of this Exhibit A. The amount of revenues used in the calculations pursuant to Section 3(c) above shall exclude (i) any additional fees agreed to by Producers and Gatherer for additional facilities installed by Gatherer pursuant to Section 2(b), Section 2(c), Section 5(a), Section 5(b)(2), Section 6(c), Section 6(d) or Section 6(f) of this Exhibit A, (ii) any revenues earned or expected to be earned by Gatherer for services on the Barnett Gathering Systems for Gas received at the Barnett Receipt Points other than Producers’ Gas and MV Mitigation Gas, (iii) any revenues attributable to Fuel Gas or to electricity costs, and (iv) any revenues earned by Gatherer to the extent allocated to any Capital Project installed by or on behalf of Gatherer in accordance with Section 13 of this Exhibit A. Any capital expenditures made by Gatherer on behalf of third parties on the Barnett Gathering Systems shall not be included in the Barnett Cap Ex, Actual Barnett Cap Ex, Projected Barnett Cap Ex, Actual Barnett Compression Expense or Revised Projected Barnett Compression Expense under this Section 3. To the extent capital was expended by the Gatherer for the benefit of Producers (with respect to Producers’ Gas or MV Mitigation Gas) and third parties (with respect to Gas of such third parties), the parties will endeavor to allocate the portion of the capital expended (or projected to be expended) on behalf of the Producers for inclusion in this calculation while excluding the portion allocated to third parties.

(h) Year. As used in this Section 3 of this Exhibit A, the term “Year” means a calendar year or a period of 12 calendar months, as the case may be.

(a) Producers’ Obligation. Producers commit and agree to deliver to Gatherer for gathering on the Barnett Gathering Systems in each Year during the Minimum Volume Period no less than the Adjusted Barnett Annual Minimum Volume for each such Year. The exclusive remedies for any failure of Producers to comply with their obligations under the preceding sentence are set forth in Section 4(b) of this Exhibit A.

(b) Deficit Volumes. If Annual Barnett Gathered Volumes in the first Year (2009) of the Minimum Volume Period (which for purposes of this Section 4(b) shall be deemed to begin on the Deemed Start Date as defined in Section 4(g) below) are less than the Adjusted Barnett Annual Minimum Volume for such first Year, then such deficit volume (up to, but not more than, 10% of the Adjusted Barnett Annual Minimum Volume for such first Year and reflected in Mcf’s) shall be carried forward to the second Year (2010) and added to the Adjusted Barnett Annual Minimum Volume for such second Year. If there is a shortfall in the first Year in excess of 10% of the Adjusted Barnett Annual Minimum Volume for such first Year, then Producers shall pay Gatherer in cash, no later than 30 Days following the receipt by Producers from Gatherer of an invoice therefor, accompanied by reasonable support for the amount invoiced therein, an amount equal to the shortfall volume in excess of 10% of the Adjusted Barnett Annual Minimum Volume for such first Year multiplied by the Average Barnett Fees (defined below) for such first Year, as partial liquidated and agreed damages for Producers’ failure to deliver the Adjusted Barnett Annual Minimum Volume in such first Year. If the Annual Barnett Gathered Volumes in the second Year of the Minimum Volume Period are less than the Adjusted Barnett Annual Minimum Volume for such second Year (as the Adjusted Barnett Annual Minimum Volume for such second Year may be increased as provided above), then Producers shall pay Gatherer in cash, no later than 30 Days following the receipt by Producers from Gatherer of an invoice therefor accompanied by reasonable support for the amount invoiced therein an amount equal to the shortfall volume for such second Year (expressed in Mcf’s) multiplied by the Average Barnett Fees for such second Year, as liquidated and agreed damages for Producers’ failure to deliver the Adjusted Barnett Annual Minimum Volume in such second Year. If the Annual Barnett Gathered Volumes delivered to the Barnett Gathering Systems in any Year after the second Year of the Minimum Volume Period are less than the Adjusted Barnett Annual Minimum Volume for such Year, then Producers shall pay Gatherer in cash, no later than 30 Days following the receipt by Producers from Gatherer of an invoice therefor accompanied by reasonable support for the amount invoiced therein for an amount equal to the shortfall volume for such Year (expressed in Mcf’s) multiplied by the Average Barnett Fees for the Year in which such shortfall volume occurred, as liquidated and agreed damages for Producers’ failure to deliver the Barnett Annual Minimum Volume in such Year. As used herein, the term “Average Barnett Fee” means, for each Year in the Minimum Volume Period, the Barnett Fee specified in Schedule A2 for Receipt Point Pressures between ** to ** psig for each such Year, escalated as specified in such Schedule A2 and subject to redetermination in accordance with Section 3 of this Exhibit A.

(c) Barnett Excess Volumes. Annual Barnett Excess Volumes shall be accumulated as a credit to be used to reduce the Adjusted Barnett Annual Minimum Volume in future Years as provided herein. Annual Barnett Excess Volumes shall be used to first reduce the Adjusted Barnett Annual Minimum Volume in the last Year of the Minimum Volume Period and then once the Adjusted Barnett Annual Minimum Volume for such Year is completely satisfied from such Annual Barnett Excess Volumes, any remaining Annual Barnett Excess Volumes will credited to the Adjusted Barnett Annual Minimum Volume for the preceding Year or Years.

(d) Adjusted Barnett Annual Minimum Volume. The “Adjusted Barnett Annual Minimum Volume” shall be determined for each Year in the Minimum Volume Period, solely for purposes of the calculation under Section 4(b) above, as follows: for each such Year the Barnett Annual Minimum Volume, as shown in Schedule A6, shall be (i) decreased by (w)

volumes of Producers’ Gas not delivered in such Year that are attributable to Barnett Delayed Connections, (x) any Force Majeure Volumes or Maintenance Suspension Volumes not delivered in such Year, (y) the Annual Barnett Excess Volumes, if any, that are applicable to such Year as provided in Section 4(c) above, and (z) upon any termination of Gatherer’s rights to operate the DFW Gathering System under Section 12.14, **% of any remaining DFW PDP Volumes that would have been produced in such Year and (ii) increased by (x) the volumes of Producers’ Gas attributable to Barnett Delayed Connections that are connected to a Barnett Gathering System in such Year, (y) the Force Majeure Volumes credited under clause (i)(y) above after resumption of deliveries on the affected Barnett Gathering System, and (z) in the last Year of the Minimum Volume Period, any MVC Additional Volume Wells Amount. Notwithstanding the preceding sentence, the Adjusted Barnett Annual Minimum Volume shall not be determined for the period between the Deemed Start Date and September 30, 2009 and the Barnett Annual Minimum Volume shall apply to such period for purposes of Section 4(b).

(e) No Increase in MDQ. No increase or decrease in the Adjusted Barnett Annual Minimum Volume hereunder for a Year will cause an increase or decrease in the Barnett Maximum Daily Quantity for such Year.

(f) No Suspension. Producers’ obligations to make payments under this Exhibit A shall not be suspended by the inability of Producers to deliver Producers’ Gas or MV Mitigation Gas under this Agreement due to the occurrence of Force Majeure Events affecting Producers.

(g) Deemed Start Date. Notwithstanding anything in this Agreement to the contrary, for purposes of this Section 4 the first Year shall be deemed to begin as of 12:01 a.m., CPT on July 1, 2009 (the “Deemed Start Date”), and the Annual Barnett Gathered Volumes in the first Year of the Minimum Volume Period shall include the actual volumes of Producers Gas received at the Barnett Receipt Points for the period from such Deemed Start Date to September 30, 2009.

(h) Example Calculation. An example calculation of payments that may be due under this Section 4 of Exhibit A is shown in Schedule A9.

(a) Receipt and Delivery. Producers agree to tender, or cause to be tendered, to the Barnett Receipt Points, Producers’ Gas and MV Mitigation Gas, each Day, and Gatherer agrees to accept Producers’ Gas and MV Mitigation Gas at the Barnett Receipt Points and redeliver Producers’ Gas and MV Mitigation Gas to the Barnett Delivery Points, subject to and on the terms provided in this Agreement. Nominations of Producers’ Gas and MV Mitigation Gas shall be made in accordance with the procedures in Exhibit D.

(1) Barnett MDQ. In no event shall Gatherer ever be required to accept from Producers on any of the Barnett Gathering Systems a volume of Producers’ Gas and MV Mitigation Gas in excess of the Barnett Maximum Daily Quantity for that Barnett Gathering System.

(2) Increase in MDQ. If Producers have a volume of Producers’ Gas and MV Mitigation Gas available to deliver in excess of the Barnett Maximum Daily Quantity for a Barnett Gathering System, Producers may request that Gatherer increase the Barnett Maximum Daily Quantity for that Barnett Gathering System. Such request shall be made by Notice to Gatherer stating the amount (in Mcf’s) by which Producers desire to increase the Barnett Maximum Daily Quantity and the term of such increase. Gatherer shall accept such increase in the Barnett Maximum Daily Quantity prior to December 31, 2015 to the extent excess capacity is then available on the Barnett Gathering System, taking into account commitments and offers previously made by Gatherer to third parties (including letters of intent) for capacity on that Barnett Gathering System and considering the effects such increase may have on Gatherer’s ability to maintain required pressures on that Barnett Gathering System, but for no longer than the remaining term of the Minimum Volume Period. If Gatherer makes such excess capacity available to Producers (i) the Barnett Maximum Daily Quantity shall be increased by the amount of such excess capacity made available to Producers for the term of such increase (with the Barnett Fees to apply to Producers’ Gas and MV Mitigation Gas that utilizes such increased capacity) and (ii) Producers shall commit to deliver, or pay the applicable Barnett Fees with respect to, **% of such increase in the Barnett Maximum Daily Quantity commencing on the date such increased Barnett Maximum Daily Quantity becomes effective and continuing for the term of such increase (even if such volumes are not delivered). Such commitment by Producers under clause (ii) shall not affect or reduce Producers’ obligations to pay the Barnett Fees for all Producers’ Gas and MV Mitigation Gas delivered hereunder.

(3) MDQ After End of Minimum Volume Period. Effective as of the end of the Minimum Volume Period and continuing until the end of the first full Year following the end of the Minimum Volume Period, the Barnett Maximum Daily Quantity for each Barnett Gathering System shall be redetermined to equal **% of the average daily volumes of Producers’ Gas received and gathered hereunder at the Priority 1 Service level on such Barnett Gathering System in the final 6 Months of the Minimum Volume Period, but such redetermined Barnett Maximum Daily Quantity shall not exceed the Barnett Maximum Daily Quantity in effect for such Barnett Gathering System in the last Month of the Minimum Volume Period. For each Year thereafter, the Barnett Maximum Daily Quantity for each Barnett Gathering System shall be to equal **% of the average daily volumes of Producers’ Gas received and gathered hereunder at the Priority 1 Service level on each such Barnett Gathering System in the prior Year, but such redetermined Barnett Maximum Daily Quantity shall not exceed the Barnett Maximum Daily Quantity in effect for such Barnett Gathering System in the last Month of the Minimum Volume Period.

(4) Priority 3 Service. If Producers have volumes of Producers’ Gas and MV Mitigation Gas available on a Barnett Gathering System from time to time in excess of the Barnett Maximum Daily Quantity for such Barnett Gathering System, Producers may request, and Gatherer shall provide, to the extent available, Priority 3 Service for such volumes of Producers’ Gas and MV Mitigation Gas at rates to be agreed to by the Parties.

(5) Delivery Point Changes. To the extent Producers’ Nominations of Gas to a Barnett Delivery Point or Barnett Delivery Points would not permit Gatherer to accept

the Barnett Maximum Daily Quantity on any Barnett Gathering System, Producers shall exercise commercially reasonable efforts to nominate Gas at other Barnett Delivery Points to permit Gatherer to accept the Barnett Maximum Daily Quantity on any such Barnett Gathering System.

(6) Volumes in Excess of MDQ. If (i) Producers have a volume of Producers’ Gas and MV Mitigation Gas available to deliver in excess of the Barnett Maximum Daily Quantity for a Barnett Gathering System, (ii) Producers request that Gatherer accept such volume (the “Additional Volume”) on such Barnett Gathering System, and (iii) there is no capacity available on such Barnett Gathering System at the time of such request, then within 30 Days following receipt of such request Gatherer may offer to take such actions as are necessary to make available new capacity on such Barnett Gathering System sufficient to cover the Additional Volume. If within 10 Days following Producers’ receipt of such offer the Parties have not reached an agreement on the fees that would apply to such new capacity (or if Gatherer does not make an offer within the aforesaid 30 Day period), then Producers may request and Gatherer shall execute a written release from this Agreement of the spacing/drilling units of the wells that produce the Additional Volume (the “Additional Volume Wells”). With respect to any release pursuant to the preceding paragraph, Producers shall reasonably determine the volumes of Gas that would be produced from the Additional Volume Wells over the first 3 Years of the productive life of such wells, such determination to be based on the type curve shown in Schedule A10 (the sum of such volumes, the “Projected Additional Volume Wells Amount”). The “MVC Additional Volume Wells Amount” shall be equal to the amount by which the Projected Additional Volume Wells Amount exceeds the average daily capacity of such Barnett Gathering System used by Persons other than Producers and their Affiliates over the most recent 30 Day period preceding such release for which such information is available. Once determined, the MVC Additional Volume Wells Amount shall be included in the determination of the Adjusted Barnett Annual Minimum Volume as provided in Section 4(d) of Exhibit A in the last Year of the Barnett Annual Minimum Volume Period.

(7) [Party A]. The Maximum Daily Quantity for the Barnett Central Gathering System has been established based on [Party A] providing the Barnett Delivery Points and the compression services contemplated by the [Party A] Agreement. Gatherer is not a party to the [Party A] Agreement and thus Gatherer shall have no liability to Producers for any failure of [Party A] to perform under such agreement, for any curtailment or suspension of the services provided under such agreement or for any termination or expiration of such agreement. Producers shall be responsible for all obligations to [Party A] under the [Party A] Agreement, including the payment of all fees and other amounts due or owed thereunder. Producers do not guarantee or warrant [Party A]’s performance or nonperformance. If (i) [Party A] curtails or suspends services at the Barnett Delivery Points on the Barnett Central Gathering System, including the occurrence of a force majeure event or similar interruption affecting [Party A], (ii) Producers reduce the contracted volumes of Gas or volumes of Gas delivered under the [Party A] Agreement, (iii) the pressures at any such Barnett Delivery Point increase as the result of changes by [Party A] in any Month, or (iv) the [Party A] Agreement terminates or expires without being renewed, the Parties recognize and agree

that (x) the capacity of the Barnett Central Gathering System will be reduced in varying amounts and durations until such time as those services or equivalent services are restored or replaced, (y) the Gatherer shall have no obligation to accept Producers’ Gas and MV Mitigation Gas in excess of such reduced capacity, and (c) any such reductions in capacity shall not result in an decrease in the Barnett Annual Minimum Volume. The Parties agree that the restoration or replacement of such services shall not result in an increase in the Maximum Daily Quantity for the Barnett Central Gathering System or an increase in the Barnett Annual Minimum Volume. The provisions of this Section 7 and Section 4 of Schedule A2 shall apply to any replacements of the [Party A] Agreement, whether with [Party A], its successors, or other Person providing low pressure service.

(8) Nominations. Producers may request that volumes of Producers’ Gas and MV Mitigation Gas delivered to one Barnett Gathering System be transferred to a Barnett Delivery Point serving another Barnett Gathering System. Subject to Section 5(b), Gatherer will use commercially reasonable efforts to accommodate such request subject to (i) excess capacity being available to make such cross system movement and (ii) the pressures in the system served by such Barnett Delivery Point being able to accommodate the requested volume.

(c) Equivalent Quantities. Gatherer shall, as nearly as practicable each Day, deliver for Producers’ account Equivalent Quantities of Gas at the Barnett Delivery Points. All receipts and deliveries of Producers’ Gas and MV Mitigation Gas less System Fuel and Losses shall be balanced on a MMBtu basis, and all quantities referred to herein shall be adjusted for the Gross Heating Value thereof.

(d) Equal Receipt and Delivery. The Parties intend that Producers’ Gas and MV Mitigation Gas will be received and delivered hereunder at reasonably uniform rates, and Producers shall not, in any manner, use any Barnett Gathering System for storage or peaking purposes without Gatherer’s prior written approval, which approval may be withheld in Gatherer’s discretion.

(e) Proration. Producers shall, at all times, be holders of Priority 1 Service with respect to all Producers’ Gas and MV Mitigation Gas received by the Barnett Gathering Systems up to the Barnett Maximum Daily Quantity, subject to Gatherer’s obligations under third party gas gathering agreements relating to any of the Barnett Gathering Systems in effect on September 30, 2009 under which Gatherer provides a similar level of service. If capacity on a Barnett Gathering System is curtailed or reduced, or capacity is insufficient for the needs of all shippers desiring to use such capacity, the holders of Priority 3 Service will be curtailed first, the holders of Priority 2 Service will be curtailed next, and the holders of Priority 1 Service shall be curtailed last. As among the holders of Priority 1 Service, subject to the terms of the Additional Agreement, the capacity available to Priority 1 Service under the preceding sentence shall be allocated among the holders of Priority 1 Service based on the Economic Value of each contract granting such Priority 1 Service, with the contract having the highest Economic Value being the last Gas curtailed. As among the holders of Priority 2 Service, the capacity available to Priority 2 Service (if any) under the first sentence of this paragraph shall be allocated among the holders of such Priority 2 Service based on the percentage derived by dividing the volume of Gas nominated by each holder of Priority 2 Service by the total volume of Gas nominated by all

holders of Priority 2 Service, in each case as such nominations exist as of the first of the relevant Month or, if applicable, such other day as such nominations are required to be made. As among holders of Priority 3 Service, the capacity available to Priority 3 Service (if any) under the first sentence of this Section 5(e) of Exhibit A shall be fully interruptible.

(f) Information. Each Party will furnish or cause to be furnished to the other Party hereto all data required to accurately account for all Producers’ Gas and MV Mitigation Gas received and delivered hereunder.

(g) Third Party Arrangements. Producers shall make, or cause to be made, all necessary arrangements with other pipelines or third parties at or upstream of the Barnett Receipt Points and at or downstream of the Barnett Delivery Points to effect Gatherer’s receipt and delivery of Producers’ Gas and MV Mitigation Gas. Such arrangements must be coordinated with Gatherer’s Gas Control Department and must, at all times, be acceptable to Gatherer, in its sole discretion.

(h) Allocations. The Barnett Receipt Points and Barnett Delivery Points may be at locations through which other volumes of Gas are being measured. As a result, the measurement of Producers’ Gas and MV Mitigation Gas under this Agreement may involve the allocation of Gas delivered. Upon the written request from a Party to the other Party, the Party receiving such request will furnish or cause to be furnished to the other Party hereto all data reasonably available to the furnishing Party that is required to account as accurately as reasonably possible for all Gas received and delivered hereunder.

(i) Although Producers shall retain title to Producers’ Gas and MV Mitigation Gas delivered to Gatherer at the Barnett Receipt Points hereunder, Producers’ Gas and MV Mitigation Gas shall constitute part of the supply of Gas from all sources to the Barnett Gathering Systems, and as such Gatherer shall, subject to its obligation to deliver an Equivalent Quantity each Day and to the following provisions of this Section 5(i), have the right to commingle Producers’ Gas and MV Mitigation Gas with Gas of other Persons.

(ii) If (A) a Person other than Producers or their Affiliates delivers Gas to a Barnett Gathering System and (B) with respect to such Barnett Gathering System Producers or their Affiliates have a processing agreement downstream of such Barnett Gathering System with respect to Producers’ Gas and MV Mitigation Gas moved through such Barnett Gathering System, then prior to such Gas being delivered to such Barnett Gathering System Gatherer shall take (or require the third party producer to take) such actions as may be necessary to determine the Btu content of the Gas stream that would be delivered to such Barnett Gathering System by such Person (the “Third Party Btu Content”). If any such third party Gas has a Third Party Btu Content that is ** Btus higher or lower than the average Btu content of Producers’ Gas and MV Mitigation Gas delivered to such Barnett Gathering System based on the most recent Gas quality sample for which Btu content information is available (“Applicable Third Party Gas”), then Gatherer will provide Notice to Producers and the provisions of clause (iii) immediately below shall apply.

(iii) With respect to any Applicable Third Party Gas, Gatherer shall provide Notice to Producers of the Person proposing to move such gas over the applicable Barnett Gathering System if Gatherer receives the consent of such Person to disclose such information to Producers. For a period of 30 Days after any such Notice by Gatherer Producers and their Affiliates may pursue the establishment of a marketing arrangement with such Person whereby Producers or their Affiliates purchase such Third Party Gas at the wellhead. If Gatherer is unable to disclose information about such Person or if Producers are unable to reach an agreement with any such Person proposing to move Third Party Gas over the applicable Barnett Gathering System by the end of such 30 Day period, then promptly following request by Producers, Gatherer and Producers, together or separately, shall enter into discussions and negotiations with the applicable gas processor to effect such changes as may be necessary to eliminate or substantially mitigate any reduction in natural gas liquids that would be allocated to Producers resulting from commingling such Applicable Third Party Gas.

(iv) The provisions of this Section 5(i) shall not apply to volumes of Gas delivered under third party gathering agreements in effect on September 30, 2009.

(j) Lost and Unaccounted for Gas. Gatherer will conduct the services required to be performed by Gatherer under this Agreement using practices, methods and acts which are engaged in or which have been approved by a significant portion of the natural gas gathering industry. Producers acknowledge, however, that certain volumetric losses in Producers’ Gas and MV Mitigation Gas will occur even if such services are conducted in accordance with the preceding sentence, and such losses attributable to Lost and Unaccounted for Gas shall be shared and allocated among Producers and other third party shippers on each Barnett Gathering System in the proportion that each party delivers Gas to that Barnett Gathering System. Producers’ allocated share of Lost and Unaccounted for Gas on the Barnett Gathering Systems shall be based on actual losses on the Barnett Gathering Systems and shall not be subject to any minimum or maximum limits.

(k) Fuel Gas. Reductions in volumes of Producers’ Gas and MV Mitigation Gas due to Fuel Gas used for gathering, compression, dehydration, processing, and treating shall be shared and allocated among Producers and other third party shippers on each Barnett Gathering System in the proportion that each shipper delivers Gas to that Barnett Gathering System. Reductions due to Fuel Gas use on each Barnett Gathering System for dehydration and treating shall be shared and allocated among Producers and third party shippers as specified in Sections 2(b) and 2(c) of this Exhibit A.

(l) Drip Liquids. Producers acknowledge that certain reductions in volumes of Producers’ Gas and MV Mitigation Gas will occur due to shrinkage from Drip Liquids in each Barnett Gathering System, and such reductions attributable to Drip Liquids shall be shared and allocated among Producers and other third parties whose Gas is gathered on that Barnett Gathering System in the proportion to the C5+ constituents contained in the Gas delivered by each such shipper to the Barnett Gathering System. Such allocations shall be based on the most

recent quality analysis available to Gatherer for such Gas. Gatherer shall provide Notice to Producers from time to time of the quantities of Drip Liquids collected on the Barnett Gathering Systems and attributable to Producers’ Gas and MV Mitigation Gas. Gatherer (or Gatherer’s agent) will cause such Drip Liquids to be collected and removed from Gatherer’s tanks and sold from time to time. Within a reasonable period of time after any such sale, Gatherer (or Gatherer’s agent) shall remit or credit to Producers their allocated share of the net proceeds received from such sale of Drip Liquids less the actual, reasonable costs and expenses incurred to collect, transport, and sell such Drip Liquids. Drip Liquids shall be measured by the Drip Liquids purchaser.

(1) New Pad Connections. CEMI shall provide Gatherer prior Notice as soon as practicable of the expected date of first production for each new pad or pads with one or more Producer Wells in the Barnett AMI. Such Notice to Gatherer shall include (i) the location of the pad or pads and wells to be connected to the Barnett Gathering System, and (ii) the projected date of final completion and testing of such well or wells to be connected to the Barnett Gathering System on such pad or pads. Following such Notice, Producers and Gatherer shall reasonably cooperate with each other in developing and providing to the other Party such other information and data regarding such pads and wells reasonably requested by such Party, including, if requested by Gatherer, Producers’ good faith estimate of the Gas reserves for each such well or wells and the projected monthly production profile for the first 5 Years after initial production for each such well or wells. Because of the interrelated nature of the actions of the Parties required to obtain the necessary permits, authorizations, and rights of way from the appropriate state and local agencies and other Persons necessary to drill and complete each such well and construct the required extensions of the Barnett Gathering System to the pad or pads for such well or wells, the Parties agree to work together in good faith to obtain such permits, authorizations, and rights of way as expeditiously as reasonably practicable, as provided herein. The Parties agree to cooperate with each other and to communicate regularly regarding their efforts to obtain such permits, authorizations, and rights of way.

(2) New Well Connections. CEMI, on behalf of Producers, shall use its commercially reasonable efforts to provide Gatherer no less than 90 days’ prior Notice of the location of, and expected date of first production for, new Producer Wells in the Barnett AMI on a pad or pads that are already connected to a Barnett Gathering System. Such Notice to Gatherer shall include the projected date of final completion and testing of such well or wells located on the existing pad or pads specified in the Notice. Following such Notice, Producers and Gatherer shall reasonably cooperate with each other in developing and providing to the other Party such other information and data regarding such pads and wells reasonably requested by such Party.

(1) New Pad Connections. During the Minimum Volume Period, when CEMI, on behalf of Producers, provides Notice under Section 6(a)(1) above, then Gatherer shall cause the necessary facilities to be constructed to tie-in such pad or pads to the applicable Barnett Gathering System subject to Producers complying with their obligations under Section 6(a)(1). Gatherer shall complete such facilities by the later of (x) the date of first production of such pad or pads with one or more Producer Wells and (y) 21 Months after the date of Producers’ Notice (as the same may be extended pursuant to the following sentence, the “Completion Date”). If Gatherer is delayed in completing such facilities by (i) Force Majeure Events or (ii) the actions of Producers or their representatives that are inconsistent with the cooperation requirements of Section 6(a)(1) above, then the Completion Date for such connection shall be extended for a period equal to that during which Gatherer’s performance was precluded by such events or actions. If Gatherer fails to complete its facilities necessary to connect any such pad or pads to a Barnett Gathering System on or before the Completion Date for that pad or pads, as such Completion Date may be extended as provided above (the “Barnett Delayed Connections”), then the Producers, as their sole remedy for Gatherer failing to connect such Barnett Delayed Connections by the applicable Completion Date (but without limiting the following provisions of this Section 6(b)(1)), shall be entitled to a delay in their obligations with respect to the Adjusted Barnett Annual Minimum Volume under Section 4(d) of this Exhibit A for volumes of Producers’ Gas that would have been delivered from such Barnett Delayed Connections between the Completion Date for such Barnett Delayed Connections and the date on which such Barnett Delayed Connections are connected by Gatherer, as such delayed volumes are reasonably determined by Gatherer based on the type curve shown in Schedule A10. If at any time after Gatherer’s receipt of the notice from CEMI regarding the connection of a new pad Gatherer becomes aware that it will not be able to connect such pad to the Barnett Gathering System (whether before or after the Completion Date for such pad) due to Force Majeure Events, then Gatherer shall provide Notice thereof to CEMI as soon as practicable after becoming so aware and shall include with such Notice evidence that substantiates such inability to connect such pad (a “Pad Notice”). With respect to each pad covered by a Pad Notice, the spacing/drilling units for the wells that will produce from such pad shall be released from this Agreement pursuant to a written release executed by Gatherer and delivered to CEMI promptly following the sending of the related Pad Notice. If the release of any pad occurs after such pad has become a Barnett Delayed Connection and any volumes of Producers Gas that would have been delivered from such Barnett Delayed Connection have been included in the Adjusted Barnett Annual Minimum Volume under Section 4(d) of this Exhibit A, then the Parties shall reverse all of such adjustment as soon as practicable after the related Pad Notice.

(2) New Well Connections. During the Minimum Volume Period, when CEMI provides Notice under Section 6(a)(2) of this Exhibit A, Gatherer shall be responsible for the cost to install the pipe and ancillary equipment from the outlet flange of the meter tube of the Primary Measurement Device to the existing common gas header, including any modifications thereto, on the existing pad for the Producers Wells covered by such Notice but only where Gatherer has not installed a Gatherer’s Receipt Meter on such existing pad. Producers shall be responsible for the cost of connecting (i) such new Producer Wells on pads on a Barnett Gathering System where Gatherer has installed a Gatherer’s Receipt Meter and (ii) new Barnett Delivery Points added to the Barnett Gathering Systems for gas lift operations under Section 11 of this Exhibit A.

(3) Existing Wells. Notwithstanding Sections 6(b)(1) and (2) above, Gatherer shall only be required to use its commercially reasonable efforts to connect the wells and pads listed in Schedule A11 by the date shown for each such well or pad in Schedule A11. The volumes attributable to any such well or pad shall not be included in the calculation of the Adjusted Barnett Annual Minimum Volume if Gatherer fails to complete the connection of such well or pad by such date. Producers confirm to Gatherer that (i) the completion date shown for each such well or pad in Schedule A11 is no earlier than 21 Months from the date of Producers’ initial Notice requesting connection of such well or pad and (ii) that such dates have not been delayed by Producers at any time.

(4) MV Mitigation Gas. During the Minimum Volume Period, if requested by CEMI, Gatherer shall work with CEMI to construct new connections to the Barnett Gathering Systems to accept deliveries of MV Mitigation Gas to the extent (i) CEMI reasonably demonstrates to Gatherer that delivery of such MV Mitigation Gas would permit CEMI to meet the Barnett Annual Minimum Volume in any Year, (ii) deliveries of MV Mitigation Gas from such connections would not cause the volumes of all Gas received on such Barnett Gathering Systems to exceed the applicable Barnett Maximum Daily Quantity and otherwise would meet all applicable requirements for Producers’ Gas delivered under this Agreement, and (iii) such connections are constructed entirely at CEMI’s expense. Gas delivered through any such connection will be charged at the then prevailing Barnett Fees for Producers’ Gas delivered to such Barnett Gathering System.

(5) MAOP Limit. Notwithstanding the foregoing provisions of this Section 6, Gatherer shall not be required to make any connection to any of the Barnett Gathering Systems described in Part II of Schedule A1 if the delivery pressures at such new connection would exceed the maximum allowable operating pressures for such Barnett Gathering System.

(1) New Pad Connections. When CEMI provides Notice under Section 6(a)(1) above after the end of the Minimum Volume Period, Gatherer, at its sole discretion, will determine whether the prevailing Barnett Fees at that time will allow it to earn an acceptable return on such connection and whether or not it will make the requested connection.

(A) New Connection. If Gatherer agrees to make such a requested connection, then Gatherer will Notify Producers of its determination within 15 Days after receipt of Producers Notice and Gatherer shall use its commercially reasonable efforts to complete such connection by its Completion Date and Producers will be charged at the then prevailing Barnett Fees for Producers’ Gas delivered through such connection. Gatherer’s failure to Notify Producers shall be deemed to constitute a refusal by Gatherer to construct the requested connection.

(B) Gatherer Declines to Make Connection. If Gatherer declines to make such a requested connection, Gatherer and Producers shall enter into

discussions and negotiations to determine the gathering and other fees that would be paid to permit Gatherer to make such new connection. If the Parties reach agreement on such gathering and other fees, then Gatherer shall complete such connection as soon as reasonably practicable and such gathering and other fees shall be the Barnett Fees to be received by Gatherer hereunder for all Producers’ Gas received at the Barnett Receipt Point for that connection and Schedule A2 shall be amended to reflect such revised Barnett Fees.

(C) No Agreement. If the Parties fail to reach agreement within a reasonable period of time on the gathering and other fees with respect to a requested connection, Gatherer shall provide to Producers its estimated costs for such connection and Producers may elect to (i) if capacity is available, reimburse Gatherer for its costs to construct and complete such connection to a Barnett Gathering System (a “Reimbursed Connection”) or (ii) request and receive a release from the dedication under this Agreement for the spacing/drilling units of the affected wells if Producers reasonably determine that the terms offered for services by a third party gatherer in the Barnett AMI are more favorable than those under this Agreement. Producers shall furnish Notice to Gatherer of Producers’ election under the preceding sentence for each affected connection, and if Producers elect to reimburse Gatherer for the costs of any such connection, then (x) Gatherer shall proceed to commence and complete such connection, subject to Producers’ reimbursement of the costs therefor, and (y) all Producers’ Gas delivered through that Reimbursed Connection shall be gathered by Gatherer on the Barnett Gathering System under the terms of this Agreement, except that the prevailing Barnett Fees that apply to such Producers’ Gas shall be discounted by **% until Payout of the Reimbursed Connection occurs. Gatherer shall use good faith efforts to notify Producer no less than 60 Days prior to the date which Gatherer expects Payout of such Reimbursed Connection to occur. From and after Payout of a Reimbursed Connection, the applicable Barnett Fees that apply to Producers’ Gas from a Reimbursed Connection shall be the then prevailing undiscounted Barnett Fees. Producers shall be entitled to use the entire capacity of each Reimbursed Connection.

(2) New Well Connections. When CEMI provides Notice under Section 6(a)(2) above after the end of the Minimum Volume Period, Gatherer shall be responsible for the cost to install the pipe and ancillary equipment from the outlet flange of the meter tube of the Primary Measurement Device to the existing common gas header, including any modifications thereto, on the existing pad for the Producers Wells covered by such Notice but only where Gatherer has not installed a Gatherer’s Receipt Meter on such existing pad. Producers shall be responsible for the cost of connecting (i) such new Producer Wells on pads on a Barnett Gathering System where Gatherer has installed a Gatherer’s Receipt Meter and (ii) new Barnett Delivery Points added to the Barnett Gathering Systems for gas lift operations under Section 11 of this Exhibit A.

(d) Wells Not Operated by Producers. CEMI shall use its good faith efforts to provide Gatherer Notice of Producer Non-Operated Wells to be drilled in the Barnett AMI after September 30, 2009. Gatherer recognizes that such Notice, in some instances, may occur after a

Producer Non-Operated Well is producing. Following such Notice, Producers and Gatherer shall reasonably cooperate with each other in developing and providing to the other Party information and data regarding such well reasonably requested by the other Party; provided, the aforesaid cooperation rights shall not require Producers to take any action or make any claim against the operator of such well. Gatherer shall have the right, but not the obligation, to connect such Producer Non-Operated Wells to a Barnett Gathering System, at Gatherer’s cost. If Gatherer elects to make such a connection, then Gatherer will Notify CEMI of its determination within 15 Days after receipt of Producers initial Notice and Gatherer shall complete such connection as soon as reasonably practicable. Notwithstanding anything expressed or implied to the contrary, Gatherer’s connection to a Producer Non-Operated Well shall cover all Producers’ Gas from such well and Producers shall have no obligation or liability with respect to any other Gas produced from such well. For Producers’ Gas produced from each Producer Non-Operated Well and received, gathered, compressed, dehydrated, treated and processed, as applicable, and redelivered on and from a Barnett Gathering System, Producers will be charged at the then prevailing Barnett Fees for such Producers’ Gas. Gatherer’s failure to Notify Producers within such 15-Day period shall be deemed to constitute an election by Gatherer not to construct the connection. If Gatherer elects not to make such a connection, Gatherer shall provide to Producers a written release of the spacing/drilling unit for such Producer Non-Operated Well. If the aggregate working interest of Producers’ and their Affiliates in a spacing/drilling unit for a Producer Non-Operated Well to be connected to a Barnett Gathering System is less than **%, then Producers may, but shall not have the obligation to, comply with the Notice and connection obligations under this Section 6(d). If Producers elect not to comply with the Notice requirements under this Section 6(d) for such a Producer Non-Operated Well and the Operator of such well is not one of the Total Parties or their Affiliates, Producers may request, and Gatherer shall provide, a written release of the spacing/drilling unit for such Producer Non-Operated Well. Any capital expenditures made by Gatherer to connect Producer Non-Operated Wells to the Barnett Gathering Systems shall not be included in the Barnett Cap Ex, Actual Barnett Cap Ex, or Projected Barnett Cap Ex under Section 3 of this Exhibit A.

(e) Abandonment of Connection. If CEMI requests in a Notice delivered under this Section 6 that Gatherer connect a pad or a well to the Barnett Gathering System and such well or wells are not completed and ready to produce on or before the first Day of the 13th Month following the date of completion of the pad or other facilities for such well or wells, then Producers shall pay Gatherer an amount equal to (i) all direct costs incurred by Gatherer to complete such connection plus (ii) a disconnect fee equal to an amount that would provide Gatherer the Target IRR on the direct costs (for clarification, direct costs would not include overhead or general and administrative expenses) incurred by Gatherer with respect to the installation of such connection. Gatherer will provide CEMI a Notice of abandonment for such pad after the expiration of such period. Payment by Producers will be made 30 Days after receipt of such Notice of abandonment from Gatherer. Producers or their Affiliates, at their option, may elect to take assignment of Gatherer’s right, title, and interest in and to such pad or other facilities and related permits, authorizations, and rights of way by providing Notice to Gatherer no later than 30 Days after receipt of such Notice of abandonment, whereupon Gatherer shall assign to Producers (or their designee) all of Gatherer’s right, title, and interest in and to such pad or other facilities and related permits, authorizations, and rights of way, without any representation or warranty whatsoever, except that Gatherer shall represent that there are no liens or encumbrances created by or through Gatherer burdening Gatherer’s title to the transferred assets.

(f) New Delivery Points. CEMI, on behalf of the Producers, shall furnish Notice to Gatherer of any new Barnett Delivery Point connection desired by Producers, which Notice shall include the location of such Barnett Delivery Point, the projected Gas deliverability to such Barnett Delivery Point from the Barnett Gathering System, and such other information as Gatherer reasonably requests. Gatherer may elect to increase the deliverability of such new Barnett Delivery Point above that requested by Producers. The cost of such increased deliverability shall be borne by Gatherer. As soon as commercially practicable after Gatherer’s receipt of Producers’ Notice, Gatherer shall provide Notice to Producer of (i) the estimated cost to complete such new Barnett Delivery Point in accordance with Producers’ specifications, (ii) any increase in the deliverability of such new Barnett Delivery Point as determined by Gatherer (“Gatherer’s Increased Deliverability”) and Gatherer’s estimated cost of such increase, and (iii) the estimated date of completion of such new Barnett Delivery Point. If CEMI determines to proceed with completion of such new Barnett Delivery Point after receipt of Gatherer’s Notice, CEMI shall Notify Gatherer of such election accompanied by Producers’ agreement to pay the cost to complete such connection (or, if Gatherer has determined to increase deliverability, Producers’ proportionate share of the cost based on the estimated costs submitted by Gatherer). If Producers pay the entire cost of a new Barnett Delivery Point, Producers shall have Priority 1 Service for the deliverability of such new Barnett Delivery Point, and Gatherer shall pay to Producers (or deduct from amounts owed by Producers hereunder) a fee of $** per Mcf for third party Gas delivered at such new Barnett Delivery Point in excess of Gatherer’s Increased Deliverability. All such third party Gas shall have Priority 3 Service level. If, however, Gatherer pays the cost to increase the deliverability of any new Barnett Delivery Point, Producers shall have Priority 1 Service for the deliverability of the new Barnett Delivery Point up to the amount requested by CEMI in its Notice and Gatherer shall have the right to provide Priority 1 Service for third party Gas volumes up to the Gatherer’s Increased Deliverability for such new Barnett Delivery Point. Any capital expenditures made by Gatherer to add Gatherer’s Increased Deliverability to a Barnett Delivery Point shall not be included in the Barnett Cap Ex, Actual Barnett Cap Ex, or Projected Barnett Cap Ex under Section 3 of this Exhibit A.

(a) Receipt Point Pressures. Gatherer shall use commercially reasonable efforts to maintain the average monthly inlet pressures at the Barnett Receipt Points described in Schedule A4. Producers represent that the inlet pressures for such Barnett Receipt Points as of September 30, 2009 are within a reasonable tolerance of the pressures reflected in Schedule A4. Producers shall never deliver Gas to a Barnett Gathering System at a pressure that would exceed the maximum allowable operating pressure for such Barnett Gathering System.

(b) Lower Pressure Service. At any time or from time to time, Producers, by providing Notice to Gatherer, may request that the pressure at any of the Barnett Receipt Points listed in Part I of Schedule A4 upstream of an existing mainline compressor station be reduced to the next lowest pressure service shown in Part I of Schedule A2. If (i) adequate space is available on the applicable existing mainline compressor site to install such additional compression equipment, (ii) Gatherer can provide the lower pressure service by installing such

compression equipment, (iii) Gatherer holds or can obtain the permits or other authorizations required to own and operate such compression equipment, and (iv) Gatherer can obtain the necessary electrical service for such compression equipment, then, within 30 Days of receipt of such Notice, Gatherer will provide Notice to Producers of the period of time that would be required for Gatherer to comply with Producers’ request for such lower pressure service. Gatherer shall use commercially reasonable efforts to install the compression equipment necessary to provide service at such Barnett Receipt Point at the requested lower pressure level for the applicable Barnett Fee shown in Schedule A2 within such period of time. If such space is not available or if the installation of additional facilities are required to provide such lower pressure service, then Parties shall enter into good faith discussions to determine the additional fees to be paid to Gatherer by Producers to install such compression equipment. Producers recognize and understand that if Gatherer provides such lower pressure service at a Barnett Receipt Point that the inlet pressures at all related Barnett Receipt Points may not be reduced to the next lower tier.

(c) Increased Pressures. Producers shall have the right to request an increase in the inlet pressure requirement at any Barnett Receipt Point listed in Part I of Schedule A2 by providing Notice to Gatherer. If Producers will deliver increased volumes of Producers’ Gas and MV Mitigation Gas along with such increased pressure service, Gatherer shall implement such increased pressure service as soon as reasonably practicable. If Producers will not deliver increased volumes of Producers’ Gas and MV Mitigation Gas along with such increased pressure service, then Gatherer shall have at least 6 Months from the date of Producers’ Notice to reconfigure its facilities to accommodate such higher pressure service. Producers recognize and understand that if Gatherer provides such higher pressure service at a Barnett Receipt Point that the inlet pressure at all related Barnett Receipt Points may not be increased to the next higher tier.

(d) Frequency of Changes. For a period of 2 Years after Producers have requested, and Gatherer has provided, at a Barnett Receipt Point (i) a lower pressure service, Producers shall not request, and Gatherer shall have no obligation to honor any request by Producers to provide, a higher pressure service at such Barnett Receipt Point or (ii) a higher pressure service, Producers shall not request, and Gatherer shall have no obligation to honor any request by Producers to provide, a lower pressure service at such Barnett Receipt Point.

(e) Amendment. Any change in the level of service at a Barnett Receipt Point shall be agreed to by Producers and Gatherer through a supplement to Part I of Schedule A4 showing all affected Barnett Receipt Points, the new lower pressure or pressures, and the effective date of such lower pressure service.

(f) Delivery Point Pressures. If the pressures at any Barnett Delivery Point increase as the result of changes by a Barnett Receiving Transporter, Gatherer may raise the pressures at the applicable Barnett Receipt Points by an amount reasonably necessary to permit delivery of Producers’ Gas and MV Mitigation Gas at such Barnett Delivery Point at such higher pressures. The Barnett Fees for all Producers’ Gas and MV Mitigation Gas delivered to such Barnett Receipt Point shall, however, continue to be determined at the lower pressure tier in effect for such Barnett Receipt Point in the prior month. To the extent Producers’ Nominations of Gas to a Barnett Delivery Point or Barnett Delivery Points on any Barnett Gathering System would cause

an increase in the pressure tier on such Barnett Gathering System, Producers shall cooperate in good faith with Gatherer to nominate Gas at other Barnett Delivery Points to avoid such increase in the pressure tier on such Barnett Gathering System.

(g) Delivery. Subject to the foregoing provisions, Producers’ Gas and MV Mitigation Gas shall be delivered to Gatherer at the Barnett Receipt Points at pressures sufficient to effect delivery into Gatherer’s facilities at the Barnett Receipt Points. Delivery pressures at each Barnett Receipt Point shall not exceed the maximum allowable pressure of the Barnett Gathering System at each such Barnett Receipt Point; provided, however, neither Gatherer nor Producers shall be required to compress any Producers Gas at the wellhead in order to effectuate delivery hereunder.

(h) Fees. Subject to Section 7(f), for purposes of determining the Barnett Fees at the Barnett Receipt Points each Month, subject to Section 7(b), the average monthly inlet pressure will be determined at each Barnett Receipt Point, excluding Days in such Month on which no flow was recorded, or on which deliveries were precluded by a Force Majeure Event or maintenance operations conducted by Gatherer under Section 8.7 of the Agreement.

(1) Existing Barnett Receipt Points. The Parties recognize that Gatherer does not maintain a pad level custody transfer meter at any of the Barnett Receipt Points on September 30, 2009. Gatherer, at its sole discretion, may elect to install such pad level custody transfer meters at any Barnett Receipt Point.

(2) Producers’ Wellhead Meters. If Gatherer elects not to install a pad level custody transfer meter at a Barnett Receipt Point, the Parties have agreed to use Producers’ Wellhead Meters for custody transfer purposes. If Gatherer uses Producers’ Wellhead Meters for custody transfer purposes, Producers will share with Gatherer, at no cost to Gatherer, the signal and information from the Secondary Measurement Device, either, at Gatherer’s option, directly from the field or from an office location where the signal has been transmitted. Producers shall be responsible for maintenance and repair of such Secondary Measurement Devices. On those drill pads where Gatherer does not install a pad level custody transfer meter, Gatherer shall maintain, calibrate, and operate the Primary Measurement Devices, at Gatherer’s expense.

(3) Gatherer’s Receipt Meters. If Gatherer elects to install a pad level custody transfer meter, Gatherer shall install, at its cost, the custody transfer meters (both Primary and Secondary Measurement Devices and such meters and any new custody transfer meters installed by Gatherer under Section 8(a)(3) below are referred to as “Gatherer’s Receipt Meters”). On those drill pads where Gatherer installs pad level custody transfer meters, Producers shall maintain and operate Producers’ Wellhead Meters, at Producers expense. At the request of Producers, Gatherer will test and calibrate Producers’ meters that are upstream of Gatherer’s Receipt Meters and all such costs incurred by Gatherer to test or calibrate any of Producers’ meters, including Producers’ Wellhead Meters, shall be

promptly reimbursed by Producers. Gatherer, or its designee, shall maintain and operate Gatherer’s Receipt Meters, when installed, and the measuring stations at the Barnett Delivery Points. Producers may install, maintain, and operate, at their own expense, such check measuring equipment as desired and where appropriate. Such equipment shall be installed so as not to interfere with the operation of Gatherer’s or its designee’s measuring equipment. If Gatherer installs a pad level meter, such pad level meter will become the applicable Barnett Receipt Point at such time as the pad level meter is first placed into commercial service and the individual Producers’ Wellhead Meter will thereupon cease to be the applicable Receipt Point. With respect to any such pad level meters installed by Gatherer, Gatherer will share with Producers, at no cost to Producers, the signal and information from the Secondary Measurement Devices, either, at Producers’ option, directly from the field or from an office location where the signal has been transmitted.

(4) Primary Measurement Devices. None of the Primary Measurement Devices for Producers’ Wellhead Meters have been transferred to Gatherer. Producers agree to transfer, or cause to be transferred (free from all liens and encumbrances), to Gatherer the Primary Measurement Devices with respect to wells or pads in which Producers’ and their Affiliates or Producers’ and their Affiliates and the Total Parties owned 100% of the working interest on September 30, 2009 as soon as reasonably practicable after the Effective Date. Upon completion by Gatherer of a Gatherer’s Receipt Meter for custody transfer at an existing pad, Gatherer shall reconvey and transfer to Producers all of Gatherer’s right, title and interest in and to the meter runs that were previously transferred to Gatherer for such Producers’ Wellhead Meter. Except as provided in the preceding sentence, Gatherer shall not have any obligation to reconvey any meter runs to Producers.

(5) New Barnett Receipt Points. For each new drill pad connection, Gatherer shall install a custody transfer meter on the drill pad at such location where Producers connect, or intend to connect, three or more Producer Wells to a Barnett Gathering System at such location. Otherwise, the Parties shall rely on Producers’ Wellhead Meter for custody transfer and measurement purposes hereunder at such location.

(6) Field Telemetry. Producers will share the Field Telemetry signal or data with Gatherer, at Gatherer’s option and at no cost to Gatherer, for those Barnett Receipt Points which use a Producers’ Wellhead Meter for custody transfer purposes. Gatherer will share the Field Telemetry signal or data with Producers, at Producers’ option and at no cost to Producers, for those Barnett Receipt Points which use a Gatherer’s Receipt Meter for custody transfer purposes. If requested, Producers, on the one hand, and Gatherer, on the other hand, shall cause their respective Affiliates to make Field Telemetry available to Gatherer for Gatherer’s Receipt Meters or Producers for Producers’ Wellhead Meters, as applicable, either new or existing. For Gatherer’s Receipt Meters, Producers shall charge Gatherer its actual costs for such service prorated based on the actual capacity used by Gatherer. For Producers’ Wellhead Meters, Gatherer shall charge Producers its actual costs for such service prorated based on the actual capacity used by Producers. Additionally, costs for system upkeep, ongoing maintenance, and repairs of Field Telemetry and associated facilities to Barnett Receipt

Points which use a Producers’ Wellhead Meter (i) will be billed by Producers to Gatherer prorated by the actual capacity used by Gatherer at such times as Producers share Field Telemetry signal or data with Gatherer or (ii) will be billed by Gatherer to Producers prorated by the actual capacity used by Producers at such times as Gatherer shares Field Telemetry signal or data with Producers.

(b) Measurement Practices. Producers’ Wellhead Meters and Gatherer’s Receipt Meters shall be constructed, installed, and operated in accordance with the standards in Exhibit D.

(a) Producers’ Gas. All Producers’ Gas and MV Mitigation Gas delivered at the Barnett Receipt Points shall conform to the following specifications:

(1) Water: Producers’ Gas and MV Mitigation Gas shall not contain any free water.

(2) Water Vapor: Producers’ Gas and MV Mitigation Gas shall not contain more than 7 pounds of water per 1,000,000 Cubic Feet of Gas. Any Producers’ Gas or MV Mitigation Gas containing water vapor content in excess of 7 pounds of water per 1,000,000 Cubic Feet of Gas is subject to Section 2(b) of this Exhibit A.

(3) Hydrogen Sulfide: Producers’ Gas and MV Mitigation Gas shall not contain more than ¹/4 grain of hydrogen sulfide per 100 Cubic Feet of Gas at the Receipt Points, as determined by quantitative tests. Any Producers’ Gas or MV Mitigation Gas containing excess hydrogen sulfide is subject to the provisions of Section 2(c) of this Exhibit A.

(4) Total Sulfur: Producers’ Gas and MV Mitigation Gas shall not contain more than 5 grains of total sulfur per 100 Cubic Feet of Gas at the Barnett Receipt Points.

(5) Temperature: Producers’ Gas and MV Mitigation Gas shall not have a temperature less than 40ºF or more than 120 ºF.

(6) Carbon Dioxide: Producers’ Gas and MV Mitigation Gas shall not contain more than 2% by volume of carbon dioxide. Any Producers’ Gas or MV Mitigation Gas containing excess carbon dioxide is subject to the provisions of Section 2(c) of this Exhibit A.

(7) Oxygen: Producers’ Gas and MV Mitigation Gas shall not contain any oxygen.

(8) Nitrogen: Producers’ Gas and MV Mitigation Gas shall not contain more than 3% by volume of nitrogen.

(9) Nonhydrocarbons: Producers’ Gas and MV Mitigation Gas shall not contain more than 4% by volume of total nonhydrocarbons. Nonhydrocarbons shall include, but not be limited to, water, hydrogen sulfide, sulfur, carbon dioxide, oxygen and nitrogen.

(10) Other Constituents: Producers’ Gas and MV Mitigation Gas shall not contain any carbon monoxide, halogens or unsaturated hydrocarbons, and no more than 400 parts per million of hydrogen.

(11) Objectionable Liquids and Solids and Dilution: Producers’ Gas and MV Mitigation Gas shall be free of all objectionable liquids and solids, shall not contain any free hydrocarbon liquids, and shall be commercially free from dust, gums, gum-forming constituents, and other liquids or solid matter which might become separated from Producers’ Gas or MV Mitigation Gas in the course of transportation through pipelines.

(12) Gross Heating Value: Producers’ Gas and MV Mitigation Gas shall not have a Gross Heating Value less than 950 Btu’s per Cubic Foot of Gas or more than 1300 Btu’s per Cubic Foot of Gas.

(13) Hydrocarbon Dewpoint: Producers’ Gas and MV Mitigation Gas shall conform to the dewpoint specifications of the Barnett Receiving Transporters.

(b) Barnett Receiving Transporters. Notwithstanding the Gas specifications above, if a Barnett Receiving Transporter notifies Gatherer or Producers of different or additional quality specifications required at any Barnett Delivery Point that are more stringent than the specifications above, Gatherer will notify Producers of any such different or additional specifications as soon as practicable after being notified of such specifications. Such revised specifications will be considered as the quality specifications for Producers’ Gas and MV Mitigation Gas under this Agreement for as long as required by the Barnett Receiving Transporter.

(c) Failure to Meet Specifications. Notwithstanding anything in this Section 9(c) to the contrary, if Gatherer determines at any time that acceptance of Producers’ Gas or MV Mitigation Gas (even if blended as contemplated below in this Section 9(c)) does not meet any of the quality specifications in Section 9(a) (as revised in accordance with Section 9(b)) is not operationally feasible or would result in a material damage or harm to the applicable Barnett Gathering System, then Gatherer shall have the right, at its option and effective immediately upon Notice to Producers, to refuse to accept such nonconforming Producers Gas or MV Mitigation Gas, as the case may be, until Gatherer no longer believes that there is a risk of material damage or harm to the applicable Barnett Gathering System. If Producers’ Gas or MV Mitigation Gas delivered hereunder fails to meet any of the quality specifications above, Gatherer will blend, where feasible and when permitted by the applicable Barnett Receiving Transporter, such nonconforming Producers’ Gas or MV Mitigation Gas with other Producers’ Gas or MV Mitigation Gas gathered on that Barnett Gathering System to cause such nonconforming Producers’ Gas or MV Mitigation Gas to meet the Gas quality specifications hereunder and of the applicable Barnett Receiving Transporter. Producers shall reimburse

Gatherer for their prorata share of the direct costs incurred by Gatherer to blend such nonconforming Producers’ Gas or MV Mitigation Gas. If Gatherer determines at any time that the continued acceptance of such blended nonconforming Producers’ Gas or MV Mitigation Gas is not operationally feasible or would result in any material damage or harm to the applicable Barnett Gathering System, Gatherer may Notify Producers that it intends to discontinue blending and accepting such nonconforming Producers’ Gas or MV Mitigation Gas. If Gatherer provides such Notice to Producers that it intends not to accept nonconforming Gas or to discontinue blending Producers’ Gas or MV Mitigation Gas, Gatherer will work with Producers to determine the best method of treating such nonconforming Producers’ Gas or MV Mitigation Gas. Within 30 Days of the date on which Gatherer provides Notice to Producers that it will discontinue accepting or blending Producers’ Gas or MV Mitigation Gas as provided above. Gatherer shall prepare and provide to Producers an estimate of the costs to install the equipment and other facilities necessary to treat such nonconforming Producers’ Gas or MV Mitigation Gas on such Barnett Gathering System and a proposed treating fee based on such costs and other relevant factors customarily included in the determination of such a treating fee. The Parties will use good faith efforts to reach an agreement regarding a treating fee within 30 Days following the provision of such information. If such an agreement is reached, then Gatherer (at its cost) shall install and construct such facilities as soon as commercially practicable. Subject to the first sentence of this Section 9(c), during the notification process, the determination of the treating fee and the installation of the facilities, Gatherer shall continue to receive, accept and blend nonconforming Producers’ Gas and MV Mitigation Gas. Notwithstanding the foregoing, if the applicable Barnett Receiving Transporter refuses to accept such blended nonconforming Producers’ Gas or MV Mitigation Gas at any time, then Gatherer shall have the right, at its option and effective immediately upon Notice to Producers, to refuse to accept such nonconforming Producers’ Gas or MV Mitigation Gas for so long as such Barnett Receiving Transporter refuses to accept such nonconforming Producers’ Gas or MV Mitigation Gas.

(d) Acceptance of Nonconforming Gas. Without limiting the rights and obligations of the Parties pursuant to clause (c) immediately above, Gatherer may elect to accept receipt at any Barnett Receipt Point of Producers’ Gas and MV Mitigation Gas that fails to meet any of the quality specifications stated above. Such acceptance by Gatherer shall not be deemed a waiver of Gatherer’s right to refuse to accept non-specification Gas at a subsequent time, provided that Gatherer is in compliance with clause (c) immediately above in so refusing. In addition, if Producers continue to flow any Gas that fails to meet the quality specifications under this Section 9 of Exhibit A, Producers shall be responsible for (i) any fees charged by any Barnett Receiving Transporter; (ii) any costs incurred by Gatherer and agreed to by Producers in order to avoid such fees for such Gas; and (iii) any costs, expenses, damages incurred by Gatherer or assessed to Gatherer by third parties caused by such non-specification Producers’ Gas or MV Mitigation Gas. If Gatherer does not object to non-specification Producers’ Gas or MV Mitigation Gas within ** Days after the date of delivery, then Gatherer will be deemed to have waived its right to be reimbursed under the preceding sentence (but only as to such non-specification Gas volumes). Notwithstanding the foregoing, Producers shall always be responsible for fees charged by a Barnett Receiving Transporter due to non-specification Producers’ Gas or MV Mitigation Gas and will indemnify Gatherer from Claims by a Barnett Receiving Transporter arising from non-specification Producers’ Gas or MV Mitigation Gas, unless such failure is a result of non-performance of Gatherer for services to treat non-conforming Producers’ Gas and MV Mitigation Gas provided as of September 30, 2009 or contracted with Gatherer at a later date.

11. Gas Lift Operations. Producers shall have the right to establish from time to time new delivery points on the Barnett Gathering System to permit redelivery of Producers’ Gas or MV Mitigation Gas gathered on the Barnett Gathering System to Producers or their Affiliates for use in gas lift operations in Producers’ wells on the Barnett Dedicated Properties. Upon receipt of Notice from Producers to create such a delivery point, Gatherer shall install the facilities required to establish such delivery point for gas lift operations as soon as reasonably practicable. Producers shall promptly reimburse Gatherer for all costs incurred by Gatherer to install, operate, maintain, and abandon such Barnett Delivery Point for gas lift operations. Upon completion of gas lift operations at such Barnett Delivery Point, Producers shall have the right to remove and retain, or to request that Gatherer reuse, meters, equipment, and other facilities installed by Gatherer at Producers’ expense for such gas lift operations.

12. Uneconomic Systems. After the end of the Minimum Volume Period, Gatherer shall have the right to declare, acting reasonably, that the operation of all of any Barnett Gathering System is uneconomic (as defined below) by Notifying Producers. Upon receipt of such Notice by Producers, Gatherer and Producers shall negotiate in good faith to reach agreement on additional gathering fees to be paid by Producers for Producers’ Gas and MV Mitigation Gas gathered on such Barnett Gathering System that would cause the operation of that Barnett Gathering System to be economic to Gatherer. If the Parties fail to reach agreement on such additional gathering fees within a reasonable period of time, then Gatherer will have the right, upon no less than 90 Days advance Notice of abandonment to Producers, to abandon and cease operating such Barnett Gathering System, with no further liability to Producers under this Agreement or otherwise with respect to gathering Producers’ Gas or MV Mitigation Gas on such Gathering System. Subject to the Additional Agreement, Producers, at their option, may elect to take assignment of Gatherer’s right, title, and interest in and to such Barnett Gathering System by providing Notice to Gatherer no later than 30 Days prior to the date on which Gatherer proposes to abandon such Barnett Gathering System, whereupon Gatherer shall assign to Producers (or their designee) all of Gatherer’s right, title, and interest in and to such Barnett Gathering System and any third party gathering agreements (to the extent assignable at no cost to Gatherer) on such Barnett Gathering System, without any representation or warranty whatsoever, except that Gatherer shall represent that there are no liens or encumbrances created by or through Gatherer burdening Gatherer’s title to the transferred assets. For purposes of this Section 12 of Exhibit A, a Barnett Gathering System shall be treated as uneconomic at such time as the Operating Cash Flow for that Barnett Gathering System for the 12 Months preceding such determination is negative. For purposes of the preceding sentence, “Operating Cash Flow” is defined as the earnings attributable to such Barnett Gathering System, before deducting interest, taxes, depreciation, and amortization, less normal maintenance capital, as reasonably determined by Gatherer.

13. Capital Reserve. As of September 30, 2009, Gatherer has established a $** capital reserve (as the same is reduced pursuant to the following provisions, “Producer Directed Capital Reserve”). At any time during the term of this Agreement, Producers may provide Notice to Gatherer of one or more capital projects that Producers desire to have implemented that involve one or more of the Barnett Gathering Systems in the Barnett AMI and are within the

scope of the services provided by Gatherer under this Agreement, including pipeline infrastructure, installation of treating facilities, and new Barnett Delivery Points (the “Capital Projects”). As soon as reasonably practicable following Gatherer’s receipt of any such Notice, Gatherer shall provide to Producers a suggested method of implementing the Capital Project and Gatherer’s good faith estimate of the total cost thereof. Gatherer shall provide such additional information regarding the proposed implementation and estimated cost of each Capital Project and any incremental operating costs that may be incurred by Gatherer to operate such Capital Project, as may be reasonably requested by Producers. If Producers approve Gatherer’s implementation proposal for a Capital Project and the payment of such incremental operating costs, Gatherer shall use commercially reasonable efforts to commence and complete the installation of such Capital Project; provided, if the estimated cost of such Capital Project (or the total of previous Capital Projects and the current Capital Project) exceeds the Producer Directed Capital Reserve by more than **%, then Gatherer shall not be obligated to commence such Capital Project unless and until Producers and Gatherer mutually agree upon a satisfactory method of Gatherer recovering such excess amount (the “Excess Amount”). The direct costs incurred and paid by Gatherer in connection with the installation and completion of each Capital Project, including engineering costs (other than Excess Amounts) shall be applied as a reduction of the Producer Directed Capital Reserve, and Excess Amounts shall be handled in the manner mutually agreed upon pursuant to the preceding sentence. For a period of ** years after the completion of each Capital Project, Producers shall have the right to audit the direct costs incurred and paid by Gatherer in respect of such Capital Project, including engineering costs, and Gatherer shall make available records and other data supporting and evidencing such direct costs as may be reasonably requested by Producers.

The following terms and conditions shall apply to the gathering of Producers’ Gas and (where applicable) MV Mitigation Gas on the Midcon Gathering Systems.

(a) Producers’ Commitment. Subject only to Producers’ Midcon Reservations, Producers exclusively dedicate and commit to the performance of this Agreement the Midcon Dedicated Properties, represent that the Midcon Dedicated Properties are not otherwise subject to any other gas gathering agreement or other commitment or arrangement that would permit or require Producers’ Gas from the Midcon Dedicated Properties to be gathered on any other gas gathering system, and agree not to deliver any Gas produced from the Midcon Dedicated Properties and owned or controlled by Producers or their Affiliates to any other gas gatherer, gas purchaser, gas marketer, or other Person prior to the Midcon Delivery Points. Producers agree to cause any existing or future Affiliates of Producers to be bound by, and to execute and join as a party, this Agreement. The dedication and commitment made by Producers and their Affiliates under this Agreement is a covenant running with the land.

(b) Producers’ Reservations. Producers reserve the following rights (“Producers’ Midcon Reservations”): (i) to operate wells producing from the Midcon Dedicated Properties as a reasonably prudent operator, (ii) to separate or process Gas prior to delivery at the Midcon Receipt Points so long as such Producers’ Gas and MV Mitigation Gas meets the gas specifications herein after such separation or processing, (iii) to use Gas produced from the Midcon Dedicated Properties for lease operations, and (iv) to pool, communitize, or unitize Producers’ interests in the Midcon Dedicated Properties.

(c) Transfer of Producers’ Interests. Any transfer by Producers or their Affiliates of any of their interests in the Midcon Dedicated Properties shall comply with Article 9 of this Agreement.

(d) Memorandum. Producers shall enter into and deliver to Gatherer, at Gatherer’s request, a fully recordable memorandum of this Agreement, substantially in the form of Exhibit M.

(a) Gathering and Compression Fees. As consideration for receiving Producers’ Gas and MV Mitigation Gas at each Midcon Receipt Point each Month, Producers shall pay Gatherer each Month an amount equal to the applicable Midcon Fees (expressed in $/Mcf) shown for each Midcon Gathering System in Schedule B2 applied to the volume of Producers’ Gas and MV Mitigation Gas (net of gas lift volumes) received at the Midcon Receipt Points on such Midcon Gathering System during such Month. In addition to payment of such amounts, Producers shall reimburse Gatherer each Month for Producers’ allocated share of Electric Power Charges on each Midcon Gathering System.

(b) Dehydration Service Fees. Producers’ Gas and MV Mitigation Gas delivered to the Midcon Receipt Points may have a water vapor content that exceeds the quality specification for water vapor content permitted from time to time by one or more of the Midcon Receiving Transporters. In such event, Gatherer will dehydrate, if necessary, Producers’ Gas or MV Mitigation Gas to reduce its water vapor content to 7 pounds per million Cubic Feet. The fee for such dehydration services is included in the Midcon Fees. In addition to the Midcon Fees, Gatherer will charge Producer for, or retain Gas in connection with, as applicable, Producers’ allocable share of Fuel Gas and Lost and Unaccounted for Gas incurred in connection with dehydration services performed under this Section 2(b). Gatherer shall be responsible for the costs incurred in disposing of water removed from Producers’ Gas and MV Mitigation Gas during dehydration. If the quality specification for water content is reduced below 7 pounds per million Cubic Feet by one or more of the Midcon Receiving Transporters, then the Parties shall promptly negotiate an additional fee (that includes Gatherer’s cost of capital) to be paid by Producers to reimburse Gatherer for the cost of additional dehydration services to comply with such specifications.

(c) Treating Service Fees. Producers’ Gas and MV Mitigation Gas at the Midcon Receipt Points may have carbon dioxide or hydrogen sulfide content that exceeds the quality specification for carbon dioxide or hydrogen sulfide content required from time to time by one or more of the Midcon Receiving Transporters. In such event, without limiting Gatherer’s rights under Section 8(c) of this Exhibit B, Gatherer will treat, if necessary, Producers’ Gas or MV Mitigation Gas, as applicable, to reduce the carbon dioxide content to 2% and hydrogen sulfide to not more than 1/4 grain of hydrogen sulfide per 100 Cubic Feet of Gas. The fees for Gatherer providing such treating services are included in the Midcon Fees (unless a separate treating fee is otherwise shown on Schedule B2 for a well) to the extent such services are provided by Gatherer with facilities comprising part of a Midcon Gathering System on September 30, 2009. If additional facilities are required to provide such treating services or if the quality specification for carbon dioxide or hydrogen sulfide of the Midcon Receiving Transporters is reduced below 2% and 1/4 grain of hydrogen sulfide per 100 Cubic Feet of Gas, then Parties shall promptly negotiate an additional fee (that includes Gatherer’s cost of capital) to be paid by Producers to Gatherer to provide such additional treating services. If the Parties are unable to agree upon an additional fee, then Gatherer may refuse to accept receipt of such Producers’ Gas or MV Mitigation Gas for delivery to such Midcon Receiving Transporter. Gatherers’ right to negotiate additional treating fees or right to refuse further deliveries of such Producers’ Gas or MV Mitigation Gas shall apply to each additional reduction in quality specification for carbon dioxide or hydrogen sulfide content of the Midcon Receiving Transporters. In addition to the fees referred to above, Gatherer will charge Producer for, or retain Gas in connection with, as applicable, Producers’ allocable share of Fuel Gas and Lost and Unaccounted for Gas incurred in connection with treating services performed in accordance with this Section 2(c). If Gatherer removes carbon dioxide from Producers’ Gas or MV Mitigation Gas gathered on any Midcon Gathering System, Producers shall have the right (but not the obligation) to keep title to and retain all such carbon dioxide removed from Producers’ Gas or MV Mitigation Gas. If Producers so elect to retain title to such carbon dioxide, then Producers shall be responsible (at their sole risk, cost and expense) to arrange for the taking and delivery of such carbon dioxide at and from each point on the Midcon Gathering System where such carbon dioxide is so removed, and Gatherer shall make such carbon dioxide available for taking at prevailing pressures after treating. Notwithstanding the foregoing, nothing in this Section 2(c) shall require Gatherer to install facilities or incur any capital expense associated with such delivery.

(a) For the period that commences as of July 1, 2009 and ends on June 30, 2019 (such period, the “Midcon/PRP Redetermination Period,” the Parties agree that the Midcon Fees and PRP Fees shall be subject to an annual redetermination to be conducted in accordance with this Section 3 (each such annual redetermination, an “Annual Redetermination”). The Annual Redeterminations shall be conducted as follows: (i) the first Annual Redetermination shall be for the portion of the Year commencing on July 1, 2009 and ending December 31, 2009; (ii) the next nine Annual Redeterminations shall be for the calendar Year commencing on January 1, 2010 and as of January 1 for each of the eight successive calendar Years; (iii) and the final Annual Redetermination shall be for the portion of the Year commencing January 1, 2019 and ending June 30, 2019 (each Year (or portion thereof) for which an Annual Redetermination is to be made is referred to herein as an “Annual Redetermination Period”). Commencing on the first Business Day after each Annual Redetermination Period, the Parties shall (unless Producers and Gatherer mutually agree not to conduct any particular Annual Redetermination), as promptly thereafter as is commercially practicable, enter into discussions and negotiations regarding whether all or any portion of the Midcon Fees and PRP Fees should be adjusted, which discussions and negotiations shall take into account the factors specified below in Section 3(b) of this Exhibit B.

(b) Factors for Redetermination. Gatherer and Producers acknowledge that the purposes for the inclusion by the Parties of the right to redetermine and adjust the Midcon Fees and PRP Fees under this Section 3 of Exhibit B are (i) to mitigate the high degree of uncertainty in forecasting (A) future capital expenditures (including capital expenditures related to rights of way, construction labor, maintenance, connections to or expansions or extensions of, or pipeline integrity costs, of the Midcon Gathering Systems and PRP Gathering Systems (hereinafter referred to as “Midcon and PRP Cap Ex”), (B) future compression expenses (whether capitalized or expensed) (including costs associated with rentals payments, standby fees, mobilization and demobilization, facility construction, environmental testing, pollution control equipment, permitting, acquisition of emissions allowances, maintenance, overhauls, and electricity facilities such as power lines and substations, but excluding electricity costs) (hereinafter referred to as “Midcon and PRP Compression Expense”), (C) the impact (positive or negative) on revenues realized by Gatherer related to Producers’ Gas and MV Mitigation Gas from varying Midcon Fees and PRP Fees (including varying Fees that result from changes in the Gas volume mix across Midcon Gathering Systems and PRP Gathering Systems that have varying system Fees) and (ii) to assure that after giving effect to the “True-Up Payment” (as defined herein) to be made in connection with the final Annual Redetermination and to the annual adjustments to the Midcon Fees and PRP Fees to be made as provided herein, the Midcon Fees and PRP Fees permit the Gatherer to achieve an acceptable return (expressed in terms of the unlevered, pre-income tax IRR to Gatherer) over the Midcon/PRP Redetermination Period on the actual increased or decreased cash flow as compared to cash flow forecasted as of the date of this Agreement as set forth on Schedule B8. The Parties shall as promptly as is commercially practicable on the first Business Day after each Annual Redetermination Period enter into discussions and negotiations to determine whether the Midcon Fees and PRP Fees should be

adjusted, which discussions and negotiations shall take into account (in addition to other relevant factors) that Producers and Gatherer intend, subject to the “Midcon/PRP Redetermination Cap” (as defined below) and giving effect to payment of the True-Up Payment to be made in respect of the final Annual Redetermination Period, that the net present value, discounted to July 1, 2009 at an unlevered, pre-income tax IRR of **% (“Target IRR”), of the “Annual Net Cash Flow Difference,” multiplied by **, shall be equal to zero (0), where the “Annual Net Cash Flow Difference” is (i) for the given Annual Redetermination Period the sum of the following: (A) the Total Cap Ex Difference (as defined below), (B) Estimated Cap Ex Ad Valorem Tax Change (as defined below), (C) Applicable Midcon and PRP Revenue Difference (as defined below), including the surcharge or credit as described below, and (D) the Midcon and PRP Compression Expense Difference (as defined below). For purposes of this Section 3(b), the first Annual Redetermination Period shall be deemed to have commenced on July 1, 2009 (as if this Agreement were in effect on and started as of such date) and shall end on December 31, 2009 and the final Annual Redetermination Period shall begin on January 1, 2019 and end on June 30, 2019. For purposes of adjusting the Midcon Fees and PRP Fees pursuant to this Section 3(b), the Producers and Gatherer shall determine and take into account (in addition to other relevant factors) the following:

(i) the amount of the Midcon and PRP Cap Ex projected as of September 30, 2009 to be incurred from and after July 1, 2009 for each given Annual Redetermination Period in respect of the Midcon Gathering Systems and the PRP Gathering Systems (the “Original Midcon and PRP Cap Ex Projections”) as set forth in the first line under “Capital Expenditures and Ad Valorem” in Schedule B8;

(ii) the amount of Midcon and PRP Cap Ex related to the Midcon Gathering Systems and PRP Gathering Systems actually expended by Gatherer during the Annual Redetermination Period in respect of which the Annual Redetermination is being made (the “Actual Midcon and PRP Cap Ex”);

(iii) for each Annual Redetermination Period, the difference (expressed as a positive or negative number, as applicable) between (A) the amount for such Annual Redetermination Period specified in the Original Midcon and PRP Cap Ex Projections and (B) the Actual Midcon and PRP Cap Ex for such Annual Redetermination Period (the difference for each Annual Redetermination Period, the “Total Cap Ex Difference”);

(iv) for each Annual Redetermination Period, the estimated change (expressed as a positive or negative number, as applicable) in the Midcon and PRP ad valorem tax attributable to the Total Cap Ex Difference for such Annual Redetermination Period, such estimated change to be calculated in accordance with the methodology specified in footnote 1 of Schedule B8 hereto (the difference for each Annual Redetermination Period, the “Estimated Cap Ex Ad Valorem Tax Change”);

(v) the amount of the Midcon and PRP Compression Expense projected as of September 30, 2009 for each of the Annual Redetermination Periods in respect of the Midcon Gathering Systems and PRP Gathering Systems (the “Original Midcon and PRP Compression Expense”), as set forth in the first line item under the caption “Compression Expenses” in Schedule B8;

(vi) the amount of Midcon and PRP Compression Expense actually expended by Gatherer for the Midcon Gathering Systems and PRP Gathering Systems during the Annual Redetermination Period for which such Annual Redetermination is being conducted (the “Actual Midcon and PRP Compression Expense”);

(vii) for each Annual Redetermination Period, the difference (expressed as a positive or negative number, as applicable) between (A) the amount for such Annual Redetermination Period specified in the Original Midcon and PRP Compression Expense and (B) the Actual Midcon and PRP Compression Expense for such Annual Redetermination Period (the difference for each Annual Redetermination Period, the “Midcon and PRP Compression Expense Difference”);

(viii) the revenues projected as of September 30, 2009 to be received by Gatherer from and after July 1, 2009 from Producers’ Gas and MV Mitigation Gas in respect of the Midcon Gathering Systems and PRP Gathering Systems for each of the Annual Redetermination Periods (“Original Midcon and PRP Revenue Projections”), as specified in the line item entitled “Original Midcon and PRP Revenue Projections” under the caption “Revenues from Producers” in Schedule B8;

(ix) the actual revenues realized by Gatherer in respect of the Annual Redetermination Period for which the Annual Redetermination is being made from Producers’ Gas and MV Mitigation Gas in respect to the Midcon Gathering Systems and PRP Gathering Systems (the revenues for each such Annual Redetermination Period, the “Actual Midcon and PRP Revenues”);

(x) for the Annual Redetermination Period, the difference (expressed as a positive or negative number, as applicable) between (A) the Actual Midcon and PRP Revenues for such Annual Redetermination Period and (B) the Original Midcon and PRP Revenue Projections for such Annual Redetermination Period (the amount for each Annual Redetermination Period, the “Applicable Midcon and PRP Revenue Differential”); and

(xi) for the Annual Redetermination to be made in respect of the final Annual Redetermination Period, a “true-up” payment (the “True-Up Payment”) shall be made equal to the sum of the “Ending Cash Flow Differential” (as defined below, expressed as a positive or negative number) for the Annual Redetermination Period immediately preceding the final Annual Redetermination Period and the Annual Net Cash Flow Difference (expressed as a positive or negative number) for the final Annual Redetermination Period. If the sum is a negative number, the True-Up Payment equal to such sum shall be made by Producers to Gatherer in immediately available funds promptly after the amount of such True-Up Payment is determined, or if the sum is a positive number, the True-Up Payment equal to such sum shall be made by Gatherer to Producers in immediately available funds promptly after the amount of such True-Up Payment is determined.

Taking into account the factors described in items (i) through (xi) above, the annual fee adjustment, which shall be expressed as a surcharge (or credit) expressed in $ per Mcf and applied to the then applicable Midcon Fees and PRP Fees (as then escalated and previously

adjusted pursuant to this Section 3(b); such surcharge (or credit) the “Midcon and PRP Fee Adjustment”), if any, to the Midcon Fees and PRP Fees proposed to be made in response to the Midcon/PRP Redetermination Notice, (which adjusted Midcon Fees and PRP Fees, if any, will be effective as specified in Section 3(d) of this Exhibit B), shall be such that, subject to the Midcon/PRP Redetermination Cap (as defined below) and giving effect to payment of the True-Up Payment to be made in respect of the final Annual Redetermination, the net present value, discounted to July 1, 2009 at the Target IRR, of the Annual Net Cash Flow Difference, multiplied by **, shall be equal to zero (0), with the Annual Net Cash Flow Difference to be calculated based on a determination of Increased (or Decreased) Revenues from the Midcon Fee Adjustment and PRP Fee Adjustment for such Annual Redetermination Period. Subject to the Midcon/PRP Redetermination Cap (as defined below), the amount of the annual Midcon Fee Adjustment and PRP Fee Adjustment (which adjustments are referred to herein and in Schedule B8 as a “surcharge” if such adjustment is an increase in the Midcon Fees and PRP Fees, or as a “credit” if such adjustment is a decrease in the Midcon Fees and PRP Fees) for each of the Annual Redetermination Periods (excluding the final Annual Redetermination Period) will be equal to the quotient of (i) the product of (A) the sum of (I) the Ending Cash Flow Differential (as defined below) as of the end of the Annual Redetermination Period immediately preceding the Annual Redetermination Period for which the Annual Redetermination is being made and (II) the Annual Net Cash Flow Difference for the Annual Redetermination Period for which the Annual Redetermination is being made multiplied by (B) **, divided by (ii) 100% of the actual aggregate volume (expressed in Mcf’s) of Producers’ Gas and MV Mitigation Gas received at Midcon Receipt Points and PRP Receipt Points during the preceding the period in which such Annual Redetermination is being made. The term “Ending Cash Flow Differential” for any Annual Redetermination Period is equal the product of (i) the sum the Annual Net Cash Flow Difference as of the end of such Annual Redetermination Period plus the Ending Cash Flow Differential, if any, from the Annual Redetermination Period immediately preceding such Annual Redetermination Period, multiplied by (ii) ** (as illustrated under the caption “Redetermination Calculations (Annual + Final True-Up Payment” in Schedule B8). In making any determination with respect to whether the Midcon Fees and PRP Fees should be adjusted under this Section 3(b), any reduction or increase realized in actual operating or general and administrative expenses (excluding Midcon and PRP Compression Expense) shall be disregarded for purposes of such model determination. Any Midcon Fee Adjustment and PRP Fee Adjustment made under this Section 3(b) of Exhibit B may result in a surcharge or credit in the applicable Midcon Fees and PRP Fees; provided, however, that the annual upward or downward Midcon and PRP Fee Adjustments made under this Section 3(b) of Exhibit B shall not exceed **% of the Midcon Fees and PRP Fees in effect as of the last Day of the Annual Redetermination Period in respect of which such Midcon and PRP Fee Adjustments were determined (as previously adjusted in accordance with this Section 3 and inclusive of escalation as specified in Schedule B2 for the Midcon Gathering Systems and Schedule C2 for the PRP Gathering Systems; such limitation the “Midcon/PRP Redetermination Cap”). Schedule B8 sets forth an illustrative example of the Midcon/PRP Fee Redetermination methodology assuming the first redetermination is as of January 1, 2010.

(c) Industry Expert. If, within 30 Days after the first Business Day of the period for which any Midcon and PRP Fee Adjustments are to be effective, the Parties have not entered into an amendment to this Agreement reflecting the Parties’ agreement regarding such annual adjustments to the Midcon and PRP Fee Adjustments, then either Party may notify the other of

its request to have an Industry Expert determine adjustments to the applicable Midcon and PRP Fee Adjustments, if any, and the True-Up Payment, if any (the Party to give such a notice, the “Notifying Party”, and the recipient of such a notice, the “Receiving Party”). Upon the receipt of such a request for an Industry Expert determination from the Notifying Party, the Notifying Party and Receiving Party shall confer in good faith for up to 5 Business Days to agree on the selection of an Industry Expert to determine if, taking into account the factors enumerated above in Section 3(b) of this Exhibit B, an adjustment to the Midcon Fees and PRP Fees is appropriate and, with respect to the Annual Redetermination for the final Annual Redetermination Period, the amount of any True-Up Payment that is payable. If the Parties are unable to agree upon the selection of an Industry Expert within such 5 Business Day period, then each of the Notifying Party and Receiving Party will select an Industry Expert and the two firms so selected will select a Person to serve as the Industry Expert. Following such selection of an Industry Expert, each Party shall present to the Industry Expert a written statement of its position on proposed adjustments to the Midcon Fees and PRP Fees (including its methodology for calculating such adjustments) not later than 30 Days after the selection of such Industry Expert. The Industry Expert may, within 30 Days after its receipt of such statements, request such additional information from either or both Parties as the Industry Expert may deem reasonably necessary or desirable for purposes of making its determination. Each Party agrees to promptly provide the Industry Expert with all information so requested of it. The Industry Expert shall make its determination in a manner consistent with Section 3(b) of this Exhibit B above and Schedule B8. The Industry Expert shall be instructed to determine and submit to the Parties its decision regarding (i) adjustments to all or any portion of the Midcon Fees and PRP Fees; provided, however, that any increase or decrease to any Midcon Fees and PRP Fees determined by the Industry Expert shall be subject to the Midcon/PRP Redetermination Cap, and (ii) the amount of any True-Up Payment due in respect of the final Annual Redetermination Period. The decision of the Industry Expert shall be conclusive, binding upon, and non-appealable by the Parties; provided that, the decision of the Industry Expert shall not be binding on the Gatherer unless and until it has received an opinion from its counsel that such Fees as proposed to be adjusted will be treated as qualifying income (as defined in Section 7704(d) of the Internal Revenue Code of 1986, as amended). In making a determination under this Section 3(c) of Exhibit B, an Industry Expert shall be authorized to engage such independent consultants, which may include an independent reservoir engineering firm or engineering firm that is a recognized leader in advising midstream companies on the design and estimated construction costs of gathering systems in the Midcon and PRP regions, provided that each of such consultants must not have a material conflict of interest in relation to Producers and CHK Parent, on the one hand, or Gatherer or its members, on the other hand. The costs and expenses of the Industry Expert and such other consultants shall be shared equally by the Parties.

(d) Effect of Redetermined Fee. Any Midcon Fees and PRP Fees redetermined under this Section 3 of Exhibit B shall apply as of the first day of the period in which the Annual Redetermination is being made, and shall remain in effect until the date as of which the redetermined Fees for the next Annual Redetermination are to be effective.

(e) Excluded Cap Ex, Revenues and Compression Expenses. The amount of Actual Midcon and PRP Cap Ex and Actual Midcon and PRP Compression Expense determined in accordance with this Section 3 shall exclude any capital expended (in the case of Actual Midcon and PRP Cap Ex) or costs paid (in the case of Actual Midcon and PRP Compression Expense)

for additional facilities in accordance with Section 2(b), Section 2(c), Section 5(c), Section 5(d), Section 5(f) or Section 9 of this Exhibit B or Section 2(b), Section 2(c), Section 5(b) or Section 9 of Exhibit C. The amount of revenues used in the calculations pursuant to Section 3(b) above shall exclude (i) any additional fees agreed to by Producers and Gatherer for additional facilities installed by Gatherer pursuant to Section 2(b), Section 2(c), Section 5(c), Section 5(d), Section 5(f) or Section 9 of this Exhibit B or Section 2(b), Section 2(c), Section 5(b) or Section 9 of Exhibit C, (ii) any revenues earned or projected to be earned by Gatherer for services on the Midcon Gathering Systems or PRP Gathering Systems for Gas other than Producers’ Gas and MV Mitigation Gas and (iii) any revenues attributable to Fuel Gas or electricity costs in respect of the Midcon Gathering Systems or PRP Gathering Systems. Any capital expenditures made by Gatherer for facilities that are used to flow Gas other than Producers Gas or MV Mitigation Gas received at the Midcon Receipt Points or PRP Receipt Points shall be allocated based on actual volumes of Producers Gas, MV Mitigation Gas and third party Gas flowing through such facilities with the part thereof allocated to such third party Gas to be excluded from the Actual Midcon and PRP Cap Ex under this Section 3.

(f) Fees After the Final Annual Redetermination Period. After the True-Up Payment has been paid in full, Producers and Gatherer will enter into discussions and negotiations in order to establish Fees for the Midcon Gathering Systems and PRP Gathering Systems that yield Fees (determined on a volume weighted average basis for the Midcon Gathering Systems, on the one hand, and the PRP Gathering Systems, on the other hand) effective as of July 1, 2019 equal to $** per Mcf (subject to escalation as specified in Schedule B2 for the Midcon Gathering Systems and Schedule C2 for the PRP Gathering Systems).

(a) Receipt and Delivery. Producers agree to tender, or cause to be tendered, to the Midcon Receipt Points, Producers’ Gas or MV Mitigation Gas, each Day, and Gatherer agrees to accept Producers’ Gas and MV Mitigation Gas at the Midcon Receipt Points and redeliver Producers’ Gas and MV Mitigation Gas to the Midcon Delivery Points, subject to and on the terms provided in this Agreement. Prior to June 30, 2019, if Gatherer does not have sufficient capacity to accept Producers’ Gas and MV Mitigation Gas, Gatherer shall exercise commercially reasonable efforts to construct facilities to accept such excess volumes of Producers’ Gas and MV Mitigation Gas, such construction to be completed as promptly as is commercially reasonable. If after exercising such efforts the facilities have not been constructed or Gatherer determines in good faith that it will not be able to construct such facilities exercising commercially reasonable efforts, Producers may request, and Gatherer shall promptly provide, a written release of the spacing/drilling unit for the wells that would have been served by such facilities. Nominations of Producers’ Gas and MV Mitigation Gas shall be made in accordance with the procedures in Exhibit D.

(b) Equivalent Quantities. Gatherer shall, as nearly as practicable each Day, deliver for Producers’ account Equivalent Quantities of Gas at the Midcon Delivery Points. All receipts and deliveries of Producers’ Gas and MV Mitigation Gas less System Fuel and Losses shall be balanced on a MMBtu basis, and all quantities referred to herein shall be adjusted for the Gross Heating Value thereof.

(c) Equal Receipt and Delivery. The Parties intend that Producers’ Gas and MV Mitigation Gas will be received and delivered hereunder at reasonably uniform rates, and Producers shall not, in any manner, use any Midcon Gathering System for storage or peaking purposes without Gatherer’s prior written approval, which approval may be withheld in Gatherer’s discretion.

(d) Proration. Producers shall, at all times, be holders of Priority 1 Service with respect to all Producers’ Gas and MV Mitigation Gas received by the Midcon Gathering Systems, subject to any obligations of Gatherer under third party gas gathering agreements relating to the Midcon Gathering System in effect on September 30, 2009 under which Gatherer provides a similar level of service. If capacity on a Midcon Gathering System is curtailed or reduced, or capacity is insufficient for the needs of all shippers desiring to use such capacity, the holders of Priority 3 Service will be curtailed first, the holders of Priority 2 Service will be curtailed next, and the holders of Priority 1 Service shall be curtailed last. As among the holders of Priority 1 Service, the capacity available to Priority 1 Service under the preceding sentence shall be allocated among the holders of Priority 1 Service based on the Economic Value of each contract granting such Priority 1 Service, with the contract having the highest Economic Value being the last Gas curtailed. As among the holders of Priority 2 Service, the capacity available to Priority 2 Service (if any) under the first sentence of this paragraph shall be allocated among the holders of such Priority 2 Service based on the percentage derived by dividing the volume of Gas nominated by each holder of Priority 2 Service by the total volume of Gas nominated by all holders of Priority 2 Service, in each case as such nominations exist as of the first of the relevant Month or, if applicable, such other day as such nominations are required to be made. As among holders of Priority 3 Service, the capacity available to Priority 3 Service (if any) under the first sentence of this Section 4(f) of Exhibit B shall be fully interruptible.

(e) Delivery Point Changes. To the extent Producers’ Nominations of Gas to a Midcon Delivery Point or Midcon Delivery Points would not permit Gatherer to accept the all volumes of Producers’ Gas and MV Mitigation Gas on any Midcon Gathering System, Producers shall exercise commercially reasonable efforts to nominate Gas at other Midcon Delivery Points to permit Gatherer to accept all volumes of Producers’ Gas and MV Mitigation Gas on any such Midcon Gathering System.

(g) Third Party Arrangements. Producers shall make, or cause to be made, all necessary arrangements with other pipelines or third parties at or upstream of the Midcon Receipt Points and at or downstream of the Midcon Delivery Points to effect Gatherer’s receipt and delivery of Producers’ Gas and MV Mitigation Gas. Such arrangements must be coordinated with Gatherer’s Gas Control Department and must, at all times, be acceptable to Gatherer, in its sole discretion.

(h) Allocations. The Midcon Receipt Points and Midcon Delivery Points may be at locations through which other volumes of Gas are being measured. As a result, the measurement of Producers’ Gas and MV Mitigation Gas under this Agreement may involve the allocation of

Gas delivered. Upon the written request from a Party to the other Party, the Party receiving such request will furnish or cause to be furnished to the other Party hereto all data reasonably available to the furnishing Party that is required to account as accurately as reasonably possible for all Gas received and delivered hereunder.

(i) Although Producers shall retain title to Producers’ Gas and MV Mitigation Gas delivered to Gatherer at the Midcon Receipt Points hereunder, Producers’ Gas and MV Mitigation Gas shall constitute part of the supply of Gas from all sources to the Midcon Gathering Systems, and as such Gatherer shall, subject to its obligation to deliver an Equivalent Quantity each Day and to the following provisions of this Section 4(i), have the right to commingle Producers’ Gas and MV Mitigation Gas with Gas of other Persons.

(ii) If (A) a Person other than Producers or their Affiliates delivers Gas to a Midcon Gathering System and (B) with respect to such Midcon Gathering System Producers or their Affiliates have a processing agreement downstream of such Midcon Gathering System with respect to Producers’ Gas and MV Mitigation Gas moved through such Midcon Gathering System, then prior to such Gas being delivered to such Midcon Gathering System, Gatherer shall take (or require the third party producer to take) such actions as may be necessary to determine the Btu content of the Gas stream that would be delivered to such Midcon Gathering System by such Person (the “Third Party Btu Content”). If any such third party Gas has a Third Party Btu Content that is ** Btu’s higher or lower than the average Btu content of Producers’ Gas and MV Mitigation Gas delivered to such Midcon Gathering System based on the most recent Gas quality sample for which Btu content is available (“Applicable Third Party Gas”), then Gatherer shall provide Notice to Producers and the provisions of clause (iii) immediately below shall apply.

(iii) With respect to any Applicable Third Party Gas, Gatherer shall provide Notice to Producers of the Person proposing to move such Gas over the applicable Midcon Gathering System if Gatherer receives the consent of such Person to disclose such information to Producers. For a period of 30 Days after any such Notice by Gatherer, Producers and their Affiliates may pursue the establishment of a marketing arrangement with such Person whereby Producers or their Affiliates purchase such Third Party Gas at the wellhead. If Gatherer is unable to disclose to Producers information about such Person or if Producers are unable to reach an agreement with any such Person proposing to move Third Party Gas over the applicable Midcon Gathering System by the end of such 30-Day period, then promptly following request by Producers, Gatherer and Producers, together or separately, shall enter into discussions and negotiations with the applicable gas processor to effect such changes as may be necessary to eliminate or substantially mitigate any reduction in natural gas liquids that would be allocated to Producers resulting from commingling such Applicable Third Party Gas.

(iv) The provisions of this Section 4(i) shall not apply to volumes of Gas delivered under third party gas gathering agreements in effect on September 30, 2009.

(j) Lost and Unaccounted for Gas. Gatherer will conduct the services required to be performed by Gatherer under this Agreement using practices, methods and acts which are engaged in or which have been approved by a significant portion of the natural gas gathering industry. Producers acknowledge, however, that certain volumetric losses in Producers’ Gas and MV Mitigation Gas will occur even if such services are conducted in accordance with the preceding sentence, and such losses attributable to Lost and Unaccounted for Gas shall be shared and allocated among Producers and other third party shippers on each Midcon Gathering System in the proportion that each party delivers Gas to that Midcon Gathering System. Producers’ allocated share of Lost and Unaccounted for Gas on the Midcon Gathering Systems shall be based on actual losses on the Midcon Gathering Systems and shall not be subject to any minimum or maximum limits.

(k) Fuel Gas. Reductions in volumes of Producers’ Gas and MV Mitigation Gas due to Fuel Gas used for gathering, compression, dehydration, processing, and treating shall be shared and allocated among Producers and other third party shippers on each Midcon Gathering System in the proportion that each shipper delivers Gas to that Midcon Gathering System. Reductions due to Fuel Gas use on each Midcon Gathering System for dehydration and treating shall be shared and allocated among Producers and third party shippers as specified in Sections 2(b) and 2(c) of this Exhibit B.

(l) Drip Liquids. Producers acknowledge that certain reductions in volumes of Producers’ Gas and MV Mitigation Gas will occur due to shrinkage from Drip Liquids in each Midcon Gathering System, and such reductions attributable to Drip Liquids shall be shared and allocated among Producers and other third parties whose Gas is gathered on that Midcon Gathering System in the proportion to the C5+ constituents contained in the Gas delivered by each such shipper to the Midcon Gathering System. Such allocations shall be based on the most recent quality analysis available to Gatherer for such Gas. Gatherer shall provide Notice to Producers from time to time of the quantities of Drip Liquids collected on each Midcon Gathering System and attributable to Producers’ Gas and MV Mitigation Gas. Gatherer (or Gatherer’s agent) will cause such Drip Liquids to be collected and removed from Gatherer’s tanks and sold from time to time. Within a reasonable period of time after any such sale, Gatherer (or Gatherer’s agent) shall remit or credit to Producers their allocated share of the net proceeds received from such sale of Drip Liquids less the actual, reasonable costs and expenses incurred to collect, transport, and sell such Drip Liquids. Drip Liquids shall be measured by the Drip Liquids purchaser.

(a) Notice of New Well Connections. CEMI, on behalf of Producers, shall provide Gatherer Notice of the location of, and expected date of first production for, new Producer Wells in the Midcon AMI. Such Notice to Gatherer shall include the projected date of final completion and testing of such well or wells specified in the Notice. Following such Notice, Producers and Gatherer shall reasonably cooperate with each other in developing and providing to the other Party such other information and data regarding such wells reasonably requested by such Party, including information regarding projected delivery pressures for such wells. Gatherer shall exercise its commercially reasonable efforts to make Producers’ desired connection by the later of (i) the actual date of final completion of such well or wells or (ii) 60 Days after Gatherer’s receipt of such Notice.

(1) Certain Costs. Prior to June 30, 2019, when CEMI provides Notice under Section 5(a) of this Exhibit B, Gatherer shall be responsible for the cost to install the pipe and ancillary equipment from the outlet flange of the meter tube of the Primary Measurement Device to the existing common gas header, including any modifications thereto, on the existing pad for the Producers Wells covered by such Notice but only where Gatherer has not installed a Gatherer’s Receipt Meter on such existing pad. Producers shall be responsible for the cost of connecting (i) such new Producer Wells on pads on a Midcon Gathering System where Gatherer has installed a Gatherer’s Receipt Meter and (ii) new Midcon Delivery Points added to the Midcon Gathering Systems for gas lift operations under Section 10 of this Exhibit B.

(2) MAOP Limit. Notwithstanding the foregoing provisions of this Section 6, Gatherer shall not be required to make any connection to any of the Midcon Gathering Systems described in Part II of Schedule B1 if the delivery pressures at such new connection would exceed the maximum allowable operating pressures for such Midcon Gathering System.

(c) Completion of Connections After June 30, 2019. When CEMI provides Notice under Section 5(a) above after June 30, 2019, Gatherer, at its sole discretion, will determine whether the prevailing Midcon Fees at that time will allow it to earn an acceptable return on such connection and whether or not it will make the requested connection.

(1) New Connection. If Gatherer agrees to make such a requested connection, then Gatherer will Notify Producers of its determination within 15 Days after receipt of Producers Notice and Gatherer shall use its commercially reasonable efforts to complete such connection by its Completion Date and Producers will be charged at the then current Midcon Fees for Producers’ Gas delivered through such connection. Gatherer’s failure to Notify Producers shall be deemed to constitute a refusal by Gatherer to construct the requested connection.

(2) Gatherer Declines to Make Connection. If Gatherer declines to make such a requested connection, Gatherer and Producers shall enter into discussions and negotiations to determine the gathering and other fees that would be paid to permit Gatherer to make such new connection. If the Parties reach agreement on such gathering and other fees, then Gatherer shall complete such connection as soon as reasonably practicable and such gathering and other fees shall be the Midcon Fees to be received by Gatherer hereunder for all Producers’ Gas received at the Midcon Receipt Point for that connection and Schedule B2 shall be amended to reflect such revised Midcon Fees.

(3) No Agreement. If the Parties fail to reach agreement within a reasonable period of time on the gathering and other fees with respect to a requested connection, Gatherer shall provide to Producers its estimated costs for such connection and Producers

may elect to (i) if capacity is available, reimburse Gatherer for its costs to construct and complete such connection to a Midcon Gathering System (a “Reimbursed Connection”) or (ii) request and receive a release from the dedication under this Agreement for the spacing/drilling units of the affected wells if Producers reasonably determine that the terms offered for services by a third party gatherer in the Midcon AMI are more favorable than those under this Agreement. Producers shall furnish Notice to Gatherer of Producers’ election under the preceding sentence for each affected connection, and if Producers elect to reimburse Gatherer for the costs of any such connection, then (x) Gatherer shall proceed to commence and complete such connection, subject to Producers’ reimbursement of the costs therefor, and (y) all Producers’ Gas delivered through that Reimbursed Connection shall be gathered by Gatherer on the Midcon Gathering System under the terms of this Agreement, except that the prevailing Midcon Fees that apply to such Producers’ Gas shall be discounted by **% until Payout of the Reimbursed Connection occurs. Gatherer shall use good faith efforts to notify Producer no less than 60 Days prior to the date which Gatherer expects Payout of such Reimbursed Connection to occur. From and after Payout of a Reimbursed Connection, the applicable Midcon Fees that apply to Producers’ Gas from a Reimbursed Connection shall be the then prevailing undiscounted Midcon Fees. Producers shall be entitled to use the entire capacity of each Reimbursed Connection.

(d) Wells Not Operated by Producers. CEMI shall use its good faith efforts to provide Gatherer Notice of Producer Non-Operated Wells to be drilled in the Midcon AMI after September 30, 2009. Gatherer recognizes that such Notice, in some instances, may occur after a Producer Non-Operated Well is producing. Following such Notice, Producers and Gatherer shall reasonably cooperate with each other in developing and providing to the other Party information and data regarding such well reasonably requested by the other Party; provided, the aforesaid cooperation rights shall not require Producers to take any action or make any claim against the operator of such well. Gatherer shall have the right, but not the obligation, to connect such Producer Non-Operated Wells to a Midcon Gathering System, at Gatherer’s cost. If Gatherer elects to make such a connection, then Gatherer will Notify CEMI of its determination within 15 Days after receipt of Producers initial Notice and Gatherer shall complete such connection as soon as reasonably practicable. Notwithstanding anything expressed or implied to the contrary, Gatherer’s connection to a Producer Non-Operated Well shall cover all Producers’ Gas from such well and Producers shall have no obligation or liability with respect to any other Gas produced from such well. For Producers’ Gas produced from each Producer Non-Operated Well and received, gathered, compressed, dehydrated, treated and processed, as applicable, and redelivered on and from a Midcon Gathering System, Producers will be charged at the then current Midcon Fees for such Producers’ Gas. Gatherer’s failure to Notify Producers within such 15-Day period shall be deemed to constitute an election by Gatherer not to construct the connection. If Gatherer elects not to make such a connection, Gatherer shall provide to Producers a written release of the spacing/drilling unit for such Producer Non-Operated Well. If the aggregate working interest of Producers’ and their Affiliates in a spacing/drilling unit for a Producer Non-Operated Well to be connected to a Midcon Gathering System is less than **%, then Producers may, but shall not have the obligation to, comply with the Notice and connection obligations under this Section 5d). If Producers elect not to comply with the Notice requirements under this Section 5(d) for such a Producer Non-Operated Well, Producers may request, and Gatherer shall provide, a written release of the spacing/drilling unit for such Producer

Non-Operated Well. Any capital expenditures made by Gatherer to connect Producer Non-Operated Wells to the Midcon Gathering Systems shall not be included in the Midcon Cap Ex, Actual Midcon Cap Ex, or Projected Midcon Cap Ex under Section 3 of this Exhibit B.

(e) Abandonment of Connection. If CEMI requests in a Notice delivered under this Section 5 that Gatherer connect a pad or a well to the Midcon Gathering System and such well or wells are not completed and ready to produce on or before the first Day of the 13th Month following the date of completion of the pad or other facilities for such well or wells, then Producers shall pay Gatherer an amount equal to (i) all costs incurred by Gatherer to complete such connection plus (ii) a disconnect fee equal to an amount that would provide Gatherer the Target IRR on the direct costs (for clarification, direct costs would not include overhead or general and administrative expenses) incurred by Gatherer with respect to the installation of such connection. Gatherer will provide CEMI a Notice of abandonment for such pad after the expiration of such period. Payment by Producers will be made 30 Days after receipt of such Notice of abandonment from Gatherer. Producers, at their option, may elect to take assignment of Gatherer’s right, title, and interest in and to such pad or other facilities and related permits, authorizations, and rights of way by providing Notice to Gatherer no later than 30 Days prior to the date on which Gatherer proposes to abandon such pad, whereupon Gatherer shall assign to Producers (or their designee) all of Gatherer’s right, title, and interest in and to such pad or other facilities and related permits, authorizations, and rights of way, without any representation or warranty whatsoever, except that Gatherer shall represent that there are no liens or encumbrances created by or through Gatherer burdening Gatherer’s title to the transferred assets.

(f) New Delivery Points. CEMI, on behalf of the Producers, shall furnish Notice to Gatherer of any new Midcon Delivery Point connection desired by Producers, which Notice shall include the location of such Midcon Delivery Point, the projected Gas deliverability to such Midcon Delivery Point from the Midcon Gathering System, and such other information as Gatherer reasonably requests. Gatherer may elect to increase the deliverability of such new Midcon Delivery Point above that requested by Producers. The cost of such increased deliverability shall be borne by Gatherer. As soon as commercially practicable after Gatherer’s receipt of Producers’ Notice, Gatherer shall provide Notice to Producer of (i) the estimated cost to complete such new Midcon Delivery Point in accordance with Producers’ specifications, (ii) any increase in the deliverability of such new Midcon Delivery Point as determined by Gatherer (“Gatherer’s Increased Deliverability”) and Gatherer’s estimated cost of such increase, and (iii) the estimated date of completion of such new Midcon Delivery Point. If CEMI determines to proceed with completion of such new Midcon Delivery Point after receipt of Gatherer’s Notice, CEMI shall Notify Gatherer of such election accompanied by Producers’ agreement to pay the cost to complete such connection (or, if Gatherer has determined to increase deliverability, Producers’ proportionate share of the cost based on the estimated costs submitted by Gatherer). If Producers pay the entire cost of a new Midcon Delivery Point, Producers shall have Priority 1 Service for the deliverability of such new Midcon Delivery Point, and Gatherer shall pay to Producers (or deduct from amounts owed by Producers hereunder) a fee of $** per Mcf for third party Gas delivered at such new Midcon Delivery Point in excess of Gatherer’s Increased Deliverability. All such third party Gas shall have Priority 3 Service level. If, however, Gatherer pays the cost to increase the deliverability of any new Midcon Delivery Point, Producers shall have Priority 1 Service for the deliverability of the new Midcon Delivery Point up to the amount requested by CEMI in its Notice and Gatherer shall have the right to provide

Priority 1 Service for third party Gas volumes up to the Gatherer’s Increased Deliverability for such new Midcon Delivery Point. Any capital expenditures made by Gatherer to add Gatherer’s Increased Deliverability to a Midcon Delivery Point shall not be included in the Midcon Cap Ex, Actual Midcon Cap Ex, or Projected Midcon Cap Ex under Section 3 of this Exhibit B.

(g) Dedication Overlap. If a Producer Well to be connected hereunder is located in the Midcon AMI for two or more Midcon Gathering Systems, then Producers shall elect which of such Midcon Gathering Systems to connect to, and Gatherer shall comply with Producers’ election, for such Producer Well.

(a) Receipt Point Pressures. Gatherer shall use commercially reasonable efforts to cause the average monthly inlet pressures at the Midcon Receipt Points described in Schedule B4 not to exceed the pressures specified in Schedule B4. Producers represent that the inlet pressures at the Midcon Receipt Points as of September 30, 2009 are within a reasonable tolerance of the pressures reflected in Schedule B4. If the inlet pressures at any Midcon Receipt Point exceeds the pressures specified in Schedule B4, then the Parties shall work together to identify the actions that may be taken by Gatherer to lower such inlet pressures (including installing additional facilities) and negotiate the fees to be paid by Producers to Gatherer to provide such lower pressures. Producers shall never deliver Gas to a Midcon Gathering System that would exceed the maximum allowable operating pressure for such Midcon Gathering System.

(b) Amendment. Any request for lower pressure service shall be agreed to by Producers and Gatherer through a supplement to Schedule B4 showing all affected Midcon Receipt Points, the new lower pressure or pressures, and the effective date of such lower pressure service.

(c) Increased Pressures. Producers shall have the right to request an increase in the inlet pressure requirement at any Midcon Receipt Point listed in Schedule B4 by providing Notice to Gatherer. If Producers will deliver increased volumes of Producers’ Gas and/or MV Mitigation Gas along with such increased pressure service, Gatherer shall implement such increased pressure service as soon as reasonably practicable, If Producers will not deliver increased volumes of Producers’ Gas and/or MV Mitigation Gas along with such increased pressure service, then Gatherer shall have at least six (6) Months from the date of Producers’ Notice to reconfigure its facilities to accommodate such higher pressure service. Producers recognize and understand that if Gatherer provides such higher pressure service at a Midcon Receipt Point that the inlet pressure at all related Midcon Receipt Points may not be increased to the same pressure so requested by Producers in accordance with the first sentence of this Section 6(c).

(d) Frequency of Changes. For a period of 2 Years after Producers have requested, and Gatherer has provided, at a Midcon Receipt Point (i) a lower pressure service, Producers shall not request, and Gatherer shall have no obligation to honor any request by Producers to provide, a higher pressure service at such Midcon Receipt Point or (ii) a higher pressure service, Producers shall not request, and Gatherer shall have no obligation to honor any request by Producers to provide, a lower the pressure service at such Midcon Receipt Point.

(e) Change in Delivery Point Pressure. Notwithstanding the foregoing, if the pressures at any Midcon Delivery Point increase as the result of changes by a Midcon Receiving Transporter, Gatherer may raise the pressures at the applicable Midcon Receipt Points by an amount reasonably necessary to permit delivery of Producers’ Gas and MV Mitigation Gas at such Midcon Delivery Point at such higher pressures. To the extent Producers’ Nominations of Gas to a Midcon Delivery Point or Midcon Delivery Points on any Midcon Gathering System would cause an increase in the pressure on such Midcon Gathering System, Producers shall cooperate in good faith with Gatherer to nominate Gas at other Midcon Delivery Points to avoid such increase in the pressure on such Midcon Gathering System.

(f) Delivery. Subject to the foregoing provisions, Producers’ Gas and MV Mitigation Gas shall be delivered to Gatherer at the Midcon Receipt Points at pressures sufficient to effect delivery into Gatherer’s facilities at the Midcon Receipt Points. Delivery pressures at each Midcon Receipt Point shall not exceed the maximum allowable pressure of the Midcon Gathering System at each such Midcon Receipt Point; provided, however, neither Gatherer nor Producers shall be required to compress any Producers’ Gas at the wellhead in order to effectuate delivery hereunder.

(1) Existing Midcon Receipt Points. The Parties recognize that Gatherer does not maintain a custody transfer meter at all of the Midcon Receipt Points on September 30, 2009. Gatherer, at its sole discretion, may elect to install such pad level custody transfer meters at any Midcon Receipt Point.

(2) Producers’ Wellhead Meters. For wells without a custody transfer meter at a Midcon Receipt Point, the Parties have agreed to use Producers’ Wellhead Meters for custody transfer purposes. If Gatherer uses Producers Wellhead Meters for custody transfer purposes, Producers will share with Gatherer, at no cost to Gatherer, the signal and information from the Secondary Measurement Device, either, at Gatherer’s option, directly from the field or from an office location where the signal has been transmitted. Producers’ shall be responsible for maintenance and repair of such Secondary Measurement Devices. On those drill pads where Gatherer does not install a custody transfer meter, Gatherer shall maintain, calibrate, and operate the Primary Measurement Devices, at Gatherer’s expense.

(3) Gatherer’s Receipt Meters. If Gatherer elects to install a custody transfer meter, Gatherer shall install, at its cost, such custody transfer meters (including both Primary and Secondary Measurement Devices). On those drill pads where Gatherer installs custody transfer meters, Producers shall maintain and operate Producers’ Wellhead Meters, at Producers expense. At the request of Producers, Gatherer will test and calibrate Producers’ meters that are upstream of Gatherer’s Receipt Meters and all such costs incurred by Gatherer to test or calibrate any of Producers’ meters, including Producers’ Wellhead Meters, shall be promptly reimbursed by Producers. Gatherer, or its designee, shall maintain and operate Gatherer’s Receipt Meters, when installed, and the

measuring stations at the Midcon Delivery Points. Producers may install, maintain, and operate, at their own expense, such check measuring equipment as desired and where appropriate. Such equipment shall be installed so as not to interfere with the operation of Gatherer’s or its designee’s measuring equipment. If Gatherer installs a custody transfer meter, such custody transfer meter will become the applicable Midcon Receipt Point at such time as the custody transfer meter is first placed into commercial service and the individual Producers’ Wellhead Meter will thereupon cease to be the applicable Receipt Point.

(4) Primary Measurement Devices. None of the Primary Measurement Devices for Producers’ Wellhead Meters will have been transferred to Gatherer. Producers agree to transfer (free from all liens and encumbrances) to Gatherer the Primary Measurement Devices with respect to wells or pads in which Producers’ and their Affiliates own 100% of the working interest as soon as reasonably practicable after the Effective Date. Upon completion by Gatherer of a Gatherer’s Receipt Meter for custody transfer at an existing pad, Gatherer shall reconvey and transfer to Producers all of Gatherer’s right, title and interest in and to the meter runs that were previously transferred to Gatherer for such Producers’ Wellhead Meter. Except as provided in the preceding sentence, Gatherer shall not have any obligation to reconvey any meter runs to Producers.

(5) New Midcon Receipt Points. For each new drill pad connection, Gatherer shall install a custody transfer meter on the drill pad at such location where Producers connect, or intend to connect, three or more Producer Wells to a Midcon Gathering System at such location. Otherwise, the Parties shall rely on Producers’ Wellhead Meter for custody transfer and measurement purposes hereunder at such location.

(6) Field Telemetry. Producers will share the Field Telemetry signal or data with Gatherer, at Gatherer’s option and at no cost to Gatherer, for those Midcon Receipt Points which use a Producers’ Wellhead Meter for custody transfer purposes. Gatherer will share the Field Telemetry signal or data with Producers, at Producers’ option and at no cost to Producers, for those Midcon Receipt Points which use a Gatherer’s Receipt Meter for custody transfer purposes. If requested, Producers, on the one hand, and Gatherer, on the other hand, shall cause their respective Affiliates to make Field Telemetry available to Gatherer for Gatherer’s Receipt Meters or Producers for Producers’ Wellhead Meters, as applicable, either new or existing. For Gatherer’s Receipt Meters, Producers shall charge Gatherer its actual costs for such service prorated based on the actual capacity used by Gatherer. For Producers’ Wellhead Meters, Gatherer shall charge Producers its actual costs for such service prorated based on the actual capacity used by Producers. Additionally, costs for system upkeep, ongoing maintenance, and repairs (i) will be billed by Producers to Gatherer prorated by the actual capacity used by Gatherer at such times as Producers share Field Telemetry signal or data with Gatherer, or (ii) will be billed by Gatherer to Producers prorated by the actual capacity used by Producers at such times as Gatherer shares Field Telemetry signal or data with Producer.

(b) Measurement Practices. Producers’ Wellhead Meters and Gatherer’s Receipt Meters shall be constructed, installed, and operated in accordance with the standards in Exhibit D.

(a) Producers’ Gas and MV Mitigation Gas. All Producers’ Gas and MV Mitigation Gas delivered at the Midcon Receipt Points shall conform to the following specifications:

(1) Water: Producers’ Gas and MV Mitigation Gas shall not contain any free water.

(4) Total Sulfur: Producers’ Gas and MV Mitigation Gas shall not contain more than 5 grains of total sulfur per 100 Cubic Feet of Gas at the Midcon Receipt Points.

(5) Temperature: Producers’ Gas and MV Mitigation Gas shall not have a temperature less than 40ºF or more than 120 ºF.

(8) Nitrogen: Producers’ Gas and MV Mitigation Gas shall not contain more than 3% by volume of nitrogen.

(10) Other Constituents: Producers’ Gas and MV Mitigation Gas shall not contain any carbon monoxide, halogens or unsaturated hydrocarbons, and no more than 400 parts per million of hydrogen.

(11) Objectionable Liquids and Solids and Dilution: Producers’ Gas and MV Mitigation Gas shall be free of all objectionable liquids and solids, shall not contain any free hydrocarbon liquids, and shall be commercially free from dust, gums, gum-forming constituents, and other liquids or solid matter which might become separated from Producers’ Gas nor MV Mitigation Gas in the course of transportation through pipelines.

(12) Gross Heating Value: Producers’ Gas and MV Mitigation Gas shall not have a Gross Heating Value less than 950 Btu’s per Cubic Foot of Gas or more than 1300 Btu’s per Cubic Foot of Gas.

(13) Hydrocarbon Dewpoint: Producers’ Gas and MV Mitigation Gas shall conform to the dewpoint specifications of the Midcon Receiving Transporters.

(b) Midcon Receiving Transporters. Notwithstanding the Gas specifications above, if a Midcon Receiving Transporter notifies Gatherer or Producers of different or additional quality specifications required at any Midcon Delivery Point that are more stringent than the specifications shown above, Gatherer will notify Producers of any such different or additional specifications as soon as practicable after being notified of such specifications. Such revised specifications will be considered as the quality specifications for Producers’ Gas and MV Mitigation Gas under this Agreement for as long as required by the Midcon Receiving Transporter.

(c) Failure to Meet Specifications. Notwithstanding anything in this Section 8(c) to the contrary, if Gatherer determines at any time that acceptance of Producers’ Gas or MV Mitigation Gas (even if blended as contemplated below in this Section 8(c)) does not meet any of the quality specifications in Section 8(a) (as revised in accordance with Section 8(b)) is not operationally feasible or would result in a material damage or harm to the applicable Midcon Gathering System, then Gatherer shall have the right, at its option and effective immediately upon Notice to Producers, to refuse to accept such nonconforming Producers Gas or MV Mitigation Gas, as the case may be, until Gatherer no longer believes that there is a risk of material damage or harm to the applicable Midcon Gathering System. If Producers’ Gas or MV Mitigation Gas delivered hereunder fails to meet any of the quality specifications above, Gatherer will blend, where feasible and when permitted by the applicable Midcon Receiving Transporter, such nonconforming Producers’ Gas or MV Mitigation Gas with other Producers’ Gas or MV Mitigation Gas gathered on that Midcon Gathering System to cause such nonconforming Producers’ Gas or MV Mitigation Gas to meet the Gas quality specifications hereunder and of the applicable Midcon Receiving Transporter. Producers shall reimburse Gatherer for their prorata share of the direct costs incurred by Gatherer to blend such nonconforming Producers’ Gas or MV Mitigation Gas. If Gatherer determines at any time that the continued acceptance of such blended nonconforming Producers’ Gas or MV Mitigation Gas is not operationally feasible or would result in any material damage or harm to the applicable Midcon Gathering System, Gatherer may Notify Producers that it intends to discontinue blending and accepting such nonconforming Producers’ Gas or MV Mitigation Gas. If Gatherer provides

such Notice to Producers that it intends not to accept nonconforming Gas or to discontinue blending Producers’ Gas or MV Mitigation Gas, Gatherer will work with Producers to determine the best method of treating such nonconforming Producers’ Gas or MV Mitigation Gas. Within 30 Days of the date on which Gatherer provides Notice to Producers that it will discontinue accepting or blending Producers’ Gas or MV Mitigation Gas as provided above, Gatherer shall prepare and provide to Producers’ an estimate of the costs to install equipment or facilities necessary to treat such nonconforming Producers’ Gas or MV Mitigation Gas on such Midcon Gathering System. Gatherer shall prepare and provide to Producers an estimate of the costs to install the equipment and other facilities necessary to treat such nonconforming Producers’ Gas or MV Mitigation Gas on such Midcon Gathering System and a proposed treating fee based on such costs and other relevant factors customarily included in the determination of such a treating fee. The Parties will use good faith efforts to reach an agreement regarding a treating fee within 30 Days following the provision of such information. If such an agreement is reached, then Gatherer (at its cost) shall install and construct such facilities as soon as commercially practicable. Subject to the first sentence of this Section 8(c), during the notification process, the determination of the treating fee and the installation of the facilities, Gatherer shall continue to receive, accept and blend nonconforming Producers’ Gas and MV Mitigation Gas. Notwithstanding the foregoing, if the applicable Midcon Receiving Transporter refuses to accept such blended nonconforming Producers’ Gas or MV Mitigation Gas at any time, then Gatherer shall have the right, at its option and effective immediately upon Notice to Producers, to refuse to accept such nonconforming Producers’ Gas or MV Mitigation Gas for so long as such Midcon Receiving Transporter refuses to accept such nonconforming Producers’ Gas or MV Mitigation Gas.

(d) Acceptance of Nonconforming Gas. Without limiting the rights and obligations of the Parties pursuant to clause (c) immediately above, Gatherer may elect to accept receipt at any Midcon Receipt Point of Producers’ Gas and MV Mitigation Gas that fails to meet any of the quality specifications stated above. Such acceptance by Gatherer shall not be deemed a waiver of Gatherer’s right to refuse to accept non-specification Gas at a subsequent time, provided that Gatherer is in compliance with clause (c) immediately above in so refusing. In addition, if Producers continue to flow any Gas that fails to meet the quality specifications under this Section 8 of Exhibit B, Producers shall be responsible for (i) any fees charged by any Midcon Receiving Transporter; (ii) any costs incurred by Gatherer and agreed to by Producers in order to avoid such fees for such Gas; and (iii) any costs, expenses, damages incurred by Gatherer or assessed to Gatherer by third parties caused by such non-specification Producers’ Gas or MV Mitigation Gas. If Gatherer does not object to non-specification Producers’ Gas and MV Mitigation Gas within ** Days after the date of delivery, then Gatherer will be deemed to have waived its right to be reimbursed under the preceding sentence (but only as to such non-specification Gas volumes). Notwithstanding the foregoing, Producers shall always be responsible for fees charged by a Midcon Receiving Transporter due to non-specification Producers’ Gas or MV Mitigation Gas and will indemnify Gatherer from Claims by a Midcon Receiving Transporter arising from non-specification Producers’ Gas or MV Mitigation Gas.

9. Gas Lift Operations. Producers shall have the right to establish from time to time new delivery points on the Midcon Gathering System to permit redelivery of Producers’ Gas or MV Mitigation Gas gathered on the Midcon Gathering System to Producers or their Affiliates for use in gas lift operations in Producers’ wells on the Midcon Dedicated Properties. Upon receipt of

Notice from Producers to create such a delivery point, Gatherer shall install the facilities required to establish such delivery point for gas lift operations as soon as reasonably practicable. Producers shall promptly reimburse Gatherer for all costs incurred by Gatherer to install, operate, maintain, and abandon such Midcon Delivery Point for gas lift operations. Upon completion of gas lift operations at such Midcon Delivery Point, Producers shall have the right to remove and retain, or to request that Gatherer reuse, meters, equipment, and other facilities installed by Gatherer at Producers’ expense for such gas lift operations.

10. Uneconomic Systems. After June 30, 2019, Gatherer shall have the right to declare, acting reasonably, that the operation of all of any Midcon Gathering System is uneconomic (as defined below) by Notifying Producers. Upon receipt of such Notice by Producers, Gatherer and Producers shall negotiate in good faith to reach agreement on additional gathering fees to be paid by Producers for Producers’ Gas and MV Mitigation Gas gathered on such Midcon Gathering System that would cause the operation of that Midcon Gathering System to be economic to Gatherer. If the Parties fail to reach agreement on such additional gathering fees within a reasonable period of time, then Gatherer will have the right, upon no less than 90 Days advance Notice of abandonment to Producers, to abandon and cease operating such Midcon Gathering System, with no further liability to Producers under this Agreement or otherwise with respect to gathering Producers’ Gas or MV Mitigation Gas on such Gathering System. Producers, at their option, may elect to take assignment of Gatherer’s right, title, and interest in and to such Midcon Gathering System by providing Notice to Gatherer no later than 30 Days prior to the date on which Gatherer proposes to abandon such Midcon Gathering System, whereupon Gatherer shall assign to Producers (or their designee) all of Gatherer’s right, title, and interest in and to such Midcon Gathering System and any third party gathering agreements (to the extent assignable at no cost to Gatherer) on such Midcon Gathering System, without any representation or warranty whatsoever, except that Gatherer shall represent that there are no liens or encumbrances created by or through Gatherer burdening Gatherer’s title to the transferred assets. For purposes of this Section 10 of Exhibit B, a Midcon Gathering System shall be treated as uneconomic at such time as the Operating Cash Flow for that Midcon Gathering System for the 12 Months preceding such determination is negative. For purposes of the preceding sentence, “Operating Cash Flow” is defined as the earnings attributable to such Midcon Gathering System, before deducting interest, taxes, depreciation, and amortization, less normal maintenance capital, as reasonably determined by Gatherer.

The following terms and conditions shall apply to the gathering of Producers’ Gas on the PRP Gathering Systems.

(a) Producers’ Commitment. Subject only to Producers’ PRP Reservations, Producers exclusively dedicate and commit to the performance of this Agreement Producers’ Remaining Properties, represent that Producers’ Remaining Properties are not otherwise subject to any other gas gathering agreement or other commitment or arrangement that would permit or require Producers’ Gas from Producers’ Remaining Properties to be gathered on any other gas gathering system, and agree not to deliver any Gas produced from Producers’ Remaining Properties and owned or controlled by Producers or their Affiliates to any other gas gatherer, gas purchaser, gas marketer, or other Person prior to the PRP Delivery Points. Producers agree to cause any existing or future Affiliates of Producers to be bound by, and to execute and join as a party, this Agreement. The dedication and commitment made by Producers and their Affiliates under this Agreement is a covenant running with the land.

(b) Producers’ Reservations. Producers reserve the following rights (“Producers’ PRP Reservations”): (i) to operate wells producing from Producers’ Remaining Properties as a reasonably prudent operator, (ii) to separate or process Gas prior to delivery at the PRP Receipt Points so long as such Producers’ Gas meets the gas specifications herein after such separation or processing, (iii) to use Gas produced from Producers’ Remaining Properties for lease operations, and (iv) to pool, communitize, or unitize Producers’ interests in Producers’ Remaining Properties.

(c) Transfer of Producers’ Interests. Any transfer by Producers or their Affiliates of any of their interests in Producers’ Remaining Properties shall comply with Article 9 of this Agreement.

(d) Memorandum. Producers shall enter into and deliver to Gatherer, at Gatherer’s request, a fully recordable memorandum of this Agreement, substantially in the form of Exhibit M.

(a) Gathering and Compression Fees. As consideration for receiving Producers’ Gas at each PRP Receipt Point each Month, Producers shall pay Gatherer each Month an amount equal to the applicable PRP Fees (expressed in $/Mcf) shown for each PRP Receipt Point in Schedule C2 applied to the volume of Producers’ Gas (net of gas lift volumes) received at each such PRP Receipt Point during such Month. In addition to payment of such amounts, Producers shall reimburse Gatherer each Month for Producers’ allocated share of Electric Power Charges on each PRP Gathering System.

(b) Dehydration Service Fees. Producers’ Gas delivered to the PRP Receipt Points may have a water vapor content that exceeds the quality specification for water vapor content

permitted from time to time by one or more of the PRP Receiving Transporters. In such event, Gatherer will dehydrate Producers’ Gas to reduce its water vapor content to 7 pounds per million Cubic Feet. The fee for such dehydration services is included in the PRP Fees. In addition to the PRP Fees, Gatherer will charge Producer for, or retain Gas in connection with, as applicable, Producers’ allocable share of Fuel Gas and Lost and Unaccounted for Gas incurred in connection with dehydration services performed under this Section 2(b). Gatherer shall be responsible for the costs incurred in disposing of water removed from Producers’ Gas during dehydration. If the quality specification for water content is reduced below 7 pounds per million Cubic Feet by one or more of the PRP Receiving Transporters, then the Parties shall promptly negotiate an additional fee (that includes Gatherer’s cost of capital) to be paid by Producers to reimburse Gatherer for the cost of additional dehydration services to comply with such specifications.

(c) Treating Service Fees. Producers’ Gas at the PRP Receipt Points may have carbon dioxide or hydrogen sulfide content that exceeds the quality specification for carbon dioxide or hydrogen sulfide content required from time to time by one or more of the PRP Receiving Transporters. In such event, without limiting Gatherer’s rights under Section 9(c) of this Exhibit C, Gatherer will treat Producers’ Gas to reduce the carbon dioxide content to 2% and hydrogen sulfide to not more than 1/4 grain of hydrogen sulfide per 100 Cubic Feet of Gas. The fees for Gatherer providing such treating services are included in the PRP Fees (unless a separate treating fee is otherwise shown on Schedule C2 for a well) to the extent such services are provided by Gatherer with facilities comprising part of a PRP Gathering System on September 30, 2009. If additional facilities are required to provide such treating services or if the quality specification for carbon dioxide or hydrogen sulfide of the PRP Receiving Transporters is reduced below 2% and 1/4 grain of hydrogen sulfide per 100 Cubic Feet of Gas, then Parties shall promptly negotiate an additional fee (that includes Gatherer’s cost of capital) to be paid by Producers to Gatherer to provide such additional treating services. If the Parties are unable to agree upon an additional fee, then Gatherer may refuse to accept receipt of Producers’ Gas for delivery to such PRP Receiving Transporter. Gatherers’ right to negotiate additional treating fees or right to refuse further deliveries of Producers’ Gas shall apply to each additional reduction in quality specification for carbon dioxide or hydrogen sulfide content of the PRP Receiving Transporters. In addition to the fees referred to above, Gatherer will charge Producer for, or retain Gas in connection with, as applicable, Producers’ allocable share of Fuel Gas and Lost and Unaccounted for Gas incurred in connection with treating services performed in accordance with this Section 2(c). If Gatherer removes carbon dioxide from Producers’ Gas gathered on any PRP Gathering System, Producers shall have the right (but not the obligation) to keep title to and retain all carbon dioxide removed from Producers’ Gas. If Producers so elect to retain title to such carbon dioxide, then Producers shall be responsible (at their sole risk, cost and expense) to arrange for the taking and delivery of such carbon dioxide at and from each point on the PRP Gathering System where such carbon dioxide is so removed, and Gatherer shall make such carbon dioxide available for taking at prevailing pressures after treating. Notwithstanding the foregoing, nothing in this Section 2(c) shall require Gatherer to install facilities or incur any capital expense associated with such delivery.

(a) Receipt and Delivery. Gatherer agrees to accept Producers’ Gas at the PRP Receipt Points and redeliver Producers’ Gas to the PRP Delivery Points, to the extent capacity is available, subject to and on the terms provided in this Agreement. Prior to June 30, 2019, if Gatherer does not have sufficient capacity to accept Producers Gas, Gatherer shall use all commercially reasonable and diligent efforts to construct the necessary facilities. If after the use of such efforts the necessary facilities have not been constructed or Gatherer determines in good faith that it will not be able to construct such facilities using commercially reasonable and diligent efforts, the Producers may request and Gatherer shall provide a written release of the portion of the Producers’ Remaining Properties and wells located thereon that would have been served by such Facilities. Nominations of Producers’ Gas shall be made in accordance with the procedures in Exhibit D.

(b) Equivalent Quantities. Gatherer shall, as nearly as practicable each Day, deliver for Producers’ account Equivalent Quantities of Gas at the PRP Delivery Points. All receipts and deliveries of Producers’ Gas less System Fuel and Losses shall be balanced on a MMBtu basis, and all quantities referred to herein shall be adjusted for the Gross Heating Value thereof.

(c) Equal Receipt and Delivery. The Parties intend that Producers’ Gas will be received and delivered hereunder at reasonably uniform rates, and Producers shall not, in any manner, use any PRP Gathering System for storage or peaking purposes without Gatherer’s prior written approval, which approval may be withheld in Gatherer’s discretion.

(d) Proration. Producers shall, at all times, be holders of Priority 1 Service with respect to all Producers’ Gas received by the PRP Gathering Systems, subject to obligations of Gatherer under gas gathering agreements relating to the PRP Gathering Systems in effect on September 30, 2009 to provide an equivalent level of service. If capacity on a PRP Gathering System is curtailed or reduced, or capacity is insufficient for the needs of all shippers desiring to use such capacity, the holders of Priority 3 Service will be curtailed first, the holders of Priority 2 Service will be curtailed next, and the holders of Priority 1 Service shall be curtailed last. As among the holders of Priority 1 Service, the capacity available to Priority 1 Service under the preceding sentence shall be allocated among the holders of Priority 1 Service based on the Economic Value of each contract granting such Priority 1 Service, with the contract having the highest Economic Value being the last Gas curtailed. As among the holders of Priority 2 Service, the capacity available to Priority 2 Service (if any) under the first sentence of this paragraph shall be allocated among the holders of such Priority 2 Service based on the percentage derived by dividing the volume of Gas nominated by each holder of Priority 2 Service by the total volume of Gas nominated by all holders of Priority 2 Service, in each case as such nominations exist as of the first of the relevant Month or, if applicable, such other day as such nominations are required to be made. As among holders of Priority 3 Service, the capacity available to Priority 3 Service (if any) under the first sentence of this Section 4(d) of Exhibit C shall be fully interruptible.

(e) Information. Each Party will furnish or cause to be furnished to the other Party hereto all data required to accurately account for all Producers’ Gas received and delivered hereunder.

(f) Third Party Arrangements. Producers shall make, or cause to be made, all necessary arrangements with other pipelines or third parties at or upstream of the PRP Receipt Points and at or downstream of the PRP Delivery Points to effect Gatherer’s receipt and delivery of Producers’ Gas. Such arrangements must be coordinated with Gatherer’s Gas Control Department and must, at all times, be acceptable to Gatherer, in its sole discretion.

(g) Allocations. The PRP Receipt Points and PRP Delivery Points may be at locations through which other volumes of Gas are being measured. As a result, the measurement of Producers’ Gas under this Agreement may involve the allocation of Gas delivered. Upon the written request from a Party to the other Party, the Party receiving such request will furnish or cause to be furnished to the other Party hereto all data reasonably available to the furnishing Party that is required to account as accurately as reasonably possible for all Gas received and delivered hereunder.

(i) Although Producers shall retain title to Producers’ Gas delivered to Gatherer at the PRP Receipt Points hereunder, Producers’ Gas shall constitute part of the supply of Gas from all sources to the PRP Gathering Systems, and as such Gatherer shall, subject to its obligation to deliver an Equivalent Quantity each Day and to the following provisions of this Section 4(h), have the right to commingle Producers’ Gas with Gas of other Persons.

(ii) If (A) a Person other than Producers or their Affiliates delivers Gas to a PRP Gathering System and (B) with respect to such PRP Gathering System Producers or their Affiliates have a processing agreement downstream of such PRP Gathering System with respect to Producers’ Gas moved through such system, then prior to such Gas being delivered to such system Gatherer shall take (or require the third party producer to take) such actions as may be necessary to determine the Btu content of the Gas stream that would be delivered to such PRP Gathering System by such Person (the “Third Party Btu Content”) and shall provide such Third Party Btu to Producers. If any such third party Gas has a Third Party Btu Content that is ** Btus higher or lower than the average Btu content of Producers’ Gas delivered to such PRP Gathering System over the most recent 30-Day period for which Btu content information is available (“Applicable Third Party Gas”), then Gatherer shall provide Notice to Producers and the provisions of clause (iii) immediately below shall apply.

(iii) With respect to any Applicable Third Party Gas, Gatherer shall provide Notice to Producers of the Person proposing to move such Gas over the applicable PRP Gathering System if Gatherer receives the consent of such Person to disclose such information to Producers. For a period of 30 Days after any such Notice by Gatherer, Producers and their Affiliates may pursue the establishment of a marketing arrangement with such Person whereby Producers or their Affiliates purchase such Third Party Gas at

the wellhead. If Gatherer is unable to disclose to Producers information about such Person or if Producers are unable to reach an agreement with any such Person proposing to move Third Party Gas over the applicable PRP Gathering System, then promptly following request by Producers, Gatherer and Producers shall enter into discussions and negotiations with the applicable gas processor to effect such changes as may be necessary to eliminate or substantially mitigate any reduction in natural gas liquids resulting from commingling such Applicable Third Party Gas.

(iv) The provisions of this Section 4(h) shall not apply to volumes of Gas delivered under third party gathering agreements in effect on September 30, 2009.

(i) Lost and Unaccounted for Gas. Gatherer will conduct the services required to be performed by Gatherer under this Agreement using practices, methods and acts which are engaged in or which have been approved by a significant portion of the natural gas gathering industry. Producers acknowledge, however, that certain volumetric losses in Producers’ Gas will occur even if such services are conducted in accordance with the preceding sentence, and such losses attributable to Lost and Unaccounted for Gas shall be shared and allocated among Producers and other third party shippers on each PRP Gathering System in the proportion that each party delivers Gas to that PRP Gathering System. Producers’ allocated share of Lost and Unaccounted for Gas on the PRP Gathering Systems shall be based actual losses on the PRP Gathering Systems and shall not be subject to any minimum or maximum limits.

(j) Fuel Gas. Reductions in volumes of Producers’ Gas due to Fuel Gas used for gathering, compression, dehydration, processing, and treating shall be shared and allocated among Producers and other third party shippers on each PRP Gathering System in the proportion that each shipper delivers Gas to that PRP Gathering System. Reductions due to Fuel Gas use on each PRP Gathering System for dehydration shall be shared and allocated among Producers and third party shippers as specified in Sections 2(b) and 2(c) of this Exhibit C.

(k) Drip Liquids. Producers acknowledge that certain reductions in volumes of Producers’ Gas will occur due to shrinkage from Drip Liquids in each PRP Gathering System, and such reductions attributable to Drip Liquids shall be shared and allocated among Producers and other third parties whose Gas is gathered on that PRP Gathering System in the proportion to the C5+ constituents contained in the Gas delivered by each such shipper to the PRP Gathering System. Such allocations shall be based on the most recent quality analysis available to Gatherer for such Gas. Gatherer shall provide Notice to Producers from time to time of the quantities of Drip Liquids collected on each PRP Gathering System and attributable to Producers’ Gas. Gatherer (or Gatherer’s agent) will cause such Drip Liquids to be collected and removed from Gatherer’s tanks and sold from time to time. Within a reasonable period of time after any such sale, Gatherer (or Gatherer’s agent) shall remit or credit to Producers their allocated share of the net proceeds received from such sale of Drip Liquids less the actual, reasonable costs and expenses incurred to collect, transport, and sell such Drip Liquids. Drip Liquids shall be measured by the Drip Liquids purchaser.

(a) New Receipt Points. CEMI, on behalf of the Producers, shall furnish Notice to

Gatherer of any new well connection desired by Producers to the PRP Gathering Systems, which Notice shall include the location of such new well connection, the projected Gas deliverability to the PRP Gathering System, and such other information as Gatherer reasonably requests. Upon receipt of such Notice, Gatherer and Producers shall enter into discussions and negotiations to determine the gathering and other fees that would be paid to permit Gatherer to make such new connection. If the Parties reach agreement on such gathering and other fees, then Gatherer shall complete such connection as soon as reasonably practicable and such gathering and other fees shall be the PRP Fees to be received by Gatherer hereunder for all Producers’ Gas received at the PRP Receipt Point for that connection and Schedule C2 shall be amended to reflect such revised PRP Fees.

(b) New Delivery Points. CEMI, on behalf of the Producers, shall furnish Notice to Gatherer of any new PRP Delivery Point connection desired by Producers, which Notice shall include the location of such PRP Delivery Point, the projected Gas deliverability to such PRP Delivery Point from the PRP Gathering System, and such other information as Gatherer reasonably requests. Gatherer may elect to increase the deliverability of such new PRP Delivery Point above that requested by Producers. The cost of such increased deliverability shall be borne by Gatherer. As soon as commercially practicable after Gatherer’s receipt of Producers’ Notice, Gatherer shall provide Notice to Producer of (i) the estimated cost to complete such new PRP Delivery Point in accordance with Producers’ specifications, (ii) any increase in the deliverability of such new PRP Delivery Point as determined by Gatherer (“Gatherer’s Increased Deliverability”) and Gatherer’s estimated cost of such increase, and (iii) the estimated date of completion of such new PRP Delivery Point. If CEMI determines to proceed with completion of such new PRP Delivery Point after receipt of Gatherer’s Notice, CEMI shall Notify Gatherer of such election accompanied by Producers’ agreement to pay the cost to complete such connection (or, if Gatherer has determined to increase deliverability, Producers’ proportionate share of the cost based on the estimated costs submitted by Gatherer). If Producers pay the entire cost of a new PRP Delivery Point, Producers shall have Priority 1 Service for the deliverability of such new PRP Delivery Point, and Gatherer shall pay to Producers (or deduct from amounts owed by Producers hereunder) a fee of $** per Mcf for third party Gas delivered at such new PRP Delivery Point in excess of Gatherer’s Increased Deliverability. All such third party Gas shall have Priority 3 Service level. If, however, Gatherer pays the cost to increase the deliverability of any new PRP Delivery Point, Producers shall have Priority 1 Service for the deliverability of the new PRP Delivery Point up to the amount requested by CEMI in its Notice and Gatherer shall have the right to provide Priority 1 Service for third party Gas volumes up to the Gatherer’s Increased Deliverability for such new PRP Delivery Point.

(a) Receipt Point Pressures. Gatherer shall endeavor to cause the average monthly inlet pressures at the PRP Receipt Points described in Schedule C4 not to exceed the pressures specified in Schedule C4. Producers represent that the inlet pressures for such PRP Receipt Points as of September 30, 2009 are within a reasonable tolerance of the pressures reflected in Schedule C4. If the inlet pressures at any PRP Receipt Point exceeds the pressures specified in Schedule C4, then the Parties shall work together to identify the actions that may be taken by Gatherer to lower such inlet pressures (including installing additional facilities) and to negotiate the additional fees to be paid by Producers to Gatherer to provide such lower pressures.

(b) Amendment. Any request for lower pressure service shall be agreed to by Producers and Gatherer through a supplement to Schedule C2 showing all affected PRP Receipt Points, the new lower pressure or pressures, and the effective date of such lower pressure service.

(c) Increased Pressures. Producers shall have the right to request an increase in the inlet pressure requirement at any PRP Receipt Point listed in Schedule C2 by providing Notice to Gatherer. If Producers will deliver increased volumes of Producers’ Gas along with such increased pressure service, Gatherer shall implement such increased pressure service as soon as reasonably practicable, If Producers will not deliver increased volumes of Producers’ Gas along with such increased pressure service, then Gatherer shall have at least six (6) Months from the date of Producers’ Notice to reconfigure its facilities to accommodate such higher pressure service.

(d) Frequency of Changes. For a period of 2 Years after Producers have requested, and Gatherer has provided, at a PRP Receipt Point (i) a lower pressure service, Producers shall not request, and Gatherer shall have no obligation to honor any request by Producers to provide, a higher pressure service at such PRP Receipt Point or (ii) a higher pressure service, Producers shall not request, and Gatherer shall have no obligation to honor any request by Producers to provide, a lower the pressure service at such PRP Receipt Point.

(e) Change in Delivery Point Pressure. Notwithstanding the foregoing, if the pressures at any PRP Delivery Point increase as the result of changes by a PRP Receiving Transporter, Gatherer may raise the pressures at the applicable PRP Receipt Points by an amount reasonably necessary to permit delivery of Producers’ Gas at such PRP Delivery Point at such higher pressures. To the extent Producers’ Nominations of Gas to a PRP Delivery Point or PRP Delivery Points on any PRP Gathering System would cause an increase in the pressure on such PRP Gathering System, Producers shall cooperate in good faith with Gatherer to nominate Gas at other PRP Delivery Points to avoid such increase in the pressure on such PRP Gathering System.

(f) Delivery. Subject to the foregoing provisions, Producers’ Gas shall be delivered to Gatherer at the PRP Receipt Points at pressures sufficient to effect delivery into Gatherer’s facilities at the PRP Receipt Points. Delivery pressures at each PRP Receipt Point shall not exceed the maximum allowable pressure of the PRP Gathering System at each such PRP Receipt Point; provided, however, neither Gatherer nor Producers shall be required to compress any Producers’ Gas at the wellhead in order to effectuate delivery hereunder.

(1) Existing PRP Receipt Points. The Parties recognize that Gatherer does not maintain a custody transfer meter at all of the PRP Receipt Points on September 30, 2009. Gatherer, at its sole discretion, may elect to install such well level custody transfer meters at any PRP Receipt Point.

(2) Producers’ Wellhead Meters. For wells without a custody transfer meter at a PRP Receipt Point, the Parties have agreed to use Producers’ Wellhead Meters for custody transfer purposes. If Gatherer uses Producers Wellhead Meters for custody

transfer purposes, Producers will share with Gatherer, at no cost to Gatherer, the signal and information from the Secondary Measurement Device, either, at Gatherer’s option, directly from the field or from an office location where the signal has been transmitted. Producers shall be responsible for maintenance and repair of such Secondary Measurement Devices. On those drill pads where Gatherer does not install a custody transfer meter, Gatherer shall maintain, calibrate, and operate the Primary Measurement Devices, at Gatherer’s expense.

(3) Gatherer’s Receipt Meters. If Gatherer elects to install a custody transfer meter, Gatherer shall install, at its cost, such custody transfer meters (including Primary and Secondary Measurement Devices). On those drill pads where Gatherer installs custody transfer meters, Producers shall maintain and operate Producers’ Wellhead Meters, at Producers expense. At the request of Producers, Gatherer will test and calibrate Producers’ meters that are upstream of Gatherer’s Receipt Meters and all such costs incurred by Gatherer to test or calibrate any of Producers’ meters, including Producers’ Wellhead Meters, shall be promptly reimbursed by Producers. Gatherer, or its designee, shall maintain and operate Gatherer’s Receipt Meters, when installed, and the measuring stations at the PRP Delivery Points. Producers may install, maintain, and operate, at their own expense, such check measuring equipment as desired and where appropriate. Such equipment shall be installed so as not to interfere with the operation of Gatherer’s or its designee’s measuring equipment. If Gatherer installs a custody transfer meter, such custody transfer meter will become the applicable PRP Receipt Point at such time as the custody transfer meter is first placed into commercial service and the individual Producers’ Wellhead Meter will thereupon cease to be the applicable Receipt Point. With respect to any such custody transfer meter installed by Gatherer, Gatherer will share with Producers, at no cost to Producers, the signal and information from the Secondary Measurement Devices, either, at Producers’ option, directly from the field or from an office location where the signal has been transmitted.

(4) Primary Measurement Devices. None of the Primary Measurement Devices for Producers’ Wellhead Meters will have been transferred to Gatherer. Producers agree to transfer (free from all liens and encumbrances) to Gatherer the Primary Measurement Devices with respect to wells or pads in which Producers’ and their Affiliates owned 100% of the working interest as soon as reasonably practicable after the Effective Date. Upon completion by Gatherer of a Gatherer’s Receipt Meter for custody transfer at an existing pad, Gatherer shall reconvey and transfer to Producers all of Gatherer’s right, title and interest in and to the meter runs that were previously transferred to Gatherer for such Producers’ Wellhead Meter. Except as provided in the preceding sentence, Gatherer shall not have any obligation to reconvey any meter runs to Producers.

(5) New PRP Receipt Points. For each new drill pad connection, Gatherer shall install a custody transfer meter on the drill pad at such location where Producers connect, or intend to connect, three or more Producer Wells to a PRP Gathering System at such location. Otherwise, the Parties shall rely on Producers’ Wellhead Meter for custody transfer and measurement purposes hereunder at such location.

(6) Field Telemetry. Producers will share the Field Telemetry signal or data with Gatherer, at Gatherer’s option and at no cost to Gatherer, for those PRP Receipt Points which use a Producers’ Wellhead Meter for custody transfer purposes. Gatherer will share the Field Telemetry signal or data with Producers, at Producers’ option and at no cost to Producers, for those PRP Receipt Points which use a Gatherer’s Receipt Meter for custody transfer purposes. If requested, Producers, on the one hand, and Gatherer, on the other hand shall cause their respective Affiliates to make Field Telemetry available to Gatherer for Gatherer’s Receipt Meters or Producers for Producers’ Wellhead Meters, as applicable, either new or existing. For Gatherer’s Receipt Meters, Producers shall charge Gatherer its actual costs for such service prorated based on the actual capacity used by Gatherer. For Producers’ Wellhead Meters, Gatherer shall charge Producers its actual costs for such service prorated based on the actual capacity used by Producers. Additionally, costs for system upkeep, ongoing maintenance, and repairs of Field Telemetry and associated facilities to PRP Receipt Points which use a Producers’ Wellhead Meter (i) will be billed by Producers to Gatherer prorated by the actual capacity used by Gatherer at such times as Producers share Field Telemetry signal or data with Gatherer or (ii) will be billed by Gatherer to Producers prorated by the actual capacity used by Producers at such times as Gatherer shares Field Telemetry signal or data with Producer.

(b) Measurement Practices. Producers’ Wellhead Meters and Gatherer’s Receipt Meters shall be constructed, installed, and operated in accordance with the standards in Exhibit D.

(a) Producers’ Gas. All Producers’ Gas delivered at the PRP Receipt Points shall conform to the following specifications:

(2) Water Vapor: Producers’ Gas shall not contain more than 7 pounds of water per 1,000,000 Cubic Feet of Gas. Any Producers’ Gas containing water vapor content in excess of 7 pounds of water per 1,000,000 Cubic Feet of Gas is subject to Section 2(b) of this Exhibit C.

(3) Hydrogen Sulfide: Producers’ Gas shall not contain more than ¹/4 grain of hydrogen sulfide per 100 Cubic Feet of Gas at the Receipt Points, as determined by quantitative tests. Any Producers’ Gas containing excess hydrogen sulfide is subject to the provisions of Section 2(c) of this Exhibit C.

(4) Total Sulfur: Producers’ Gas shall not contain more than 5 grains of total sulfur per 100 Cubic Feet of Gas at the PRP Receipt Points.

(5) Temperature: Producers’ Gas shall not have a temperature less than 40ºF or more than 120 ºF.

(6) Carbon Dioxide: Producers’ Gas shall not contain more than 2% by volume of carbon dioxide. Any Producers’ Gas containing excess carbon dioxide is subject to the provisions of Section 2(c) of this Exhibit C.

(8) Nitrogen: Producers’ Gas shall not contain more than 3% by volume of nitrogen.

(9) Nonhydrocarbons: Producers’ Gas shall not contain more than 4% by volume of total nonhydrocarbons. Nonhydrocarbons shall include, but not be limited to, water, hydrogen sulfide, sulfur, carbon dioxide, oxygen and nitrogen.

(10) Other Constituents: Producers’ Gas shall not contain any carbon monoxide, halogens or unsaturated hydrocarbons, and no more than 400 parts per million of hydrogen.

(11) Objectionable Liquids and Solids and Dilution: Producers’ Gas shall be free of all objectionable liquids and solids, shall not contain any free hydrocarbon liquids, and shall be commercially free from dust, gums, gum-forming constituents, and other liquids or solid matter which might become separated from Producers’ Gas in the course of transportation through pipelines.

(12) Gross Heating Value: Producers’ Gas shall not have a Gross Heating Value less than 950 Btu’s per Cubic Foot of Gas or more than 1300 Btu’s per Cubic Foot of Gas.

(13) Hydrocarbon Dewpoint: Producers’ Gas shall conform to the dewpoint specifications of the PRP Receiving Transporters.

(b) PRP Receiving Transporters. Notwithstanding the Gas specifications above, if a PRP Receiving Transporter notifies Gatherer or Producers of different or additional quality specifications required at any PRP Delivery Point that are more stringent than the specifications shown above, Gatherer will notify Producers of any such different or additional specifications as soon as practicable after being notified of such specifications. Such revised specifications will be considered as the quality specifications for Producers’ Gas under this Agreement for as long as required by the PRP Receiving Transporter.

(c) Failure to Meet Specifications. Notwithstanding anything in this Section 8(c) to the contrary, if Gatherer determines at any time that acceptance of Producers’ Gas (even if blended as contemplated below in this Section 8(c)) does not meet any of the quality specifications in Section 8(a) (as revised in accordance with Section 8(b)) is not operationally feasible or would result in a material damage or harm to the applicable PRP Gathering System, then Gatherer shall have the right, at its option and effective immediately upon Notice to Producers, to refuse to accept such nonconforming Producers Gas, as the case may be, until Gatherer no longer believes that there is a risk of material damage or harm to the applicable PRP Gathering System. If Producers’ Gas delivered hereunder fails to meet any of the quality specifications above, Gatherer will blend, where feasible and when permitted by the applicable

PRP Receiving Transporter, such nonconforming Producers’ Gas with other Producers’ Gas gathered on that PRP Gathering System to cause such nonconforming Producers’ Gas to meet the Gas quality specifications hereunder and of the applicable PRP Receiving Transporter. Producers shall reimburse Gatherer for their prorata share of the direct costs incurred by Gatherer to blend such nonconforming Producers’ Gas. If Gatherer determines at any time that the continued acceptance of such blended nonconforming Producers’ Gas is not operationally feasible or would result in any material damage or harm to the applicable PRP Gathering System, Gatherer may Notify Producers that it intends to discontinue blending and accepting such nonconforming Producers’ Gas. If Gatherer provides such Notice to Producers that it intends not to accept nonconforming Gas or to discontinue blending Producers’ Gas, Gatherer will work with Producers to determine the best method of treating such nonconforming Producers’ Gas. Within 30 Days of the date on which Gatherer provides Notice to Producers that it will discontinue accepting or blending Producers’ Gas as provided above, Gatherer shall prepare and provide to Producers an estimate of the costs to install equipment or facilities necessary to treat such nonconforming Producers’ Gas on such PRP Gathering System. Gatherer shall prepare and provide to Producers an estimate of the costs to install the equipment and other facilities necessary to treat such nonconforming Producers’ Gas on such PRP Gathering System and a proposed treating fee based on such costs and other relevant factors customarily included in the determination of such a treating fee. The Parties will use good faith efforts to reach an agreement regarding a treating fee within 30 Days following the provision of such information. If such an agreement is reached, then Gatherer (at its cost) shall install and construct such facilities as soon as commercially practicable. Subject to the first sentence of this Section 8(c), during the notification process, the determination of the treating fee and the installation of the facilities, Gatherer shall continue to receive, accept and blend nonconforming Producers’ Gas. Notwithstanding the foregoing, if the applicable PRP Receiving Transporter refuses to accept such blended nonconforming Producers’ Gas at any time, then Gatherer shall have the right, at its option and effective immediately upon Notice to Producers, to refuse to accept such nonconforming Producers’ Gas for so long as such PRP Receiving Transporter refuses to accept such nonconforming Producers’ Gas.

(d) Acceptance of Nonconforming Gas. Without limiting the rights and obligations of the Parties pursuant to clause (c) immediately above, Gatherer may elect to accept receipt at any PRP Receipt Point of Producers’ Gas that fails to meet any of the quality specifications stated above. Such acceptance by Gatherer shall not be deemed a waiver of Gatherer’s right to refuse to accept non-specification Gas at a subsequent time, provided that Gatherer is in compliance with clause (c) immediately above in so refusing. In addition, if Producers continue to flow any Gas that fails to meet the quality specifications under this Section 9 of Exhibit C, Producers shall be responsible for (i) any fees charged by any PRP Receiving Transporter; (ii) any costs incurred by Gatherer and agreed to by Producers in order to avoid such fees for such Gas; and (iii) any costs, expenses, damages incurred by Gatherer or assessed to Gatherer by third parties caused by such non-specification Producers’ Gas. If Gatherer does not object to non-specification Producers’ Gas within ** Days after the date of delivery, then Gatherer will be deemed to have waived its right to be reimbursed under the preceding sentence (but only as to such non-specification Gas volumes). Notwithstanding the foregoing, Producers shall always be responsible for fees charged by a PRP Receiving Transporter due to non-specification Producers’ Gas and will indemnify Gatherer from Claims by a PRP Receiving Transporter arising from non-specification Producers’ Gas.

9. Gas Lift Operations. Producers shall have the right to establish from time to time new delivery points on the PRP Gathering System to permit redelivery of Producers’ Gas gathered on the PRP Gathering System to Producers or their Affiliates for use in gas lift operations in Producers’ wells on Producers’ Remaining Properties. Upon receipt of Notice from Producers to create such a delivery point, Gatherer shall install the facilities required to establish such delivery point for gas lift operations as soon as reasonably practicable. Producers shall promptly reimburse Gatherer for all costs incurred by Gatherer to install, operate, maintain, and abandon such PRP Delivery Point for gas lift operations. Upon completion of gas lift operations at such PRP Delivery Point, Producers shall have the right to remove and retain, or to request that Gatherer reuse, meters, equipment, and other facilities installed by Gatherer at Producers’ expense for such gas lift operations.

10. Uneconomic Systems. After June 30, 2019, Gatherer shall have the right to declare, acting reasonably, that the operation of all of any PRP Gathering System is uneconomic (as defined below) by Notifying Producers. Upon receipt of such Notice by Producers, Gatherer and Producers shall negotiate in good faith to reach agreement on additional gathering fees to be paid by Producers for Producers’ Gas gathered on such PRP Gathering System that would cause the operation of that PRP Gathering System to be economic to Gatherer. If the Parties fail to reach agreement on such additional gathering fees within a reasonable period of time, then Gatherer will have the right, upon no less than 90 Days advance Notice of abandonment to Producers, to abandon and cease operating such PRP Gathering System, with no further liability to Producers under this Agreement or otherwise with respect to gathering Producers’ Gas on such Gathering System. Producers, at their option, may elect to take assignment of Gatherer’s right, title, and interest in and to such PRP Gathering System by providing Notice to Gatherer no later than 30 Days prior to the date on which Gatherer proposes to abandon such PRP Gathering System, whereupon Gatherer shall assign to Producers (or their designee) all of Gatherer’s right, title, and interest in and to such PRP Gathering System and any third party gathering agreements (to the extent assignable at no cost to Gatherer) on such PRP Gathering System, without any representation or warranty whatsoever, except that Gatherer shall represent that there are no liens or encumbrances created by or through Gatherer burdening Gatherer’s title to the transferred assets. For purposes of this Section 10 of Exhibit C, a PRP Gathering System shall be treated as uneconomic at such time as the Operating Cash Flow for that PRP Gathering System for the 12 Months preceding such determination is negative. For purposes of the preceding sentence, “Operating Cash Flow” is defined as the earnings attributable to such PRP Gathering System, before deducting interest, taxes, depreciation, and amortization, less normal maintenance capital, as reasonably determined by Gatherer.

1. Nomination Procedures. “Nominations” or “Nominate” means a request submitted by Producers to Gatherer for the prospective gathering of specific volumes of Producers’ Gas and/or MV Mitigation Gas on a Gathering System. The nomination procedure for each Gathering System is as follows:

(a) First-of-the-Month Nominations. Gatherer shall advise Producers of the estimated percentage of Producers’ Gas and/or MV Mitigation Gas to be consumed as System Fuel and Losses on each Gathering System for the next Month. Producers shall submit in writing to Gatherer, by facsimile or email, its total estimated volumes, in Mcf’s per Day and MMBtu’s per Day, to be delivered to Gatherer at each Receipt Point for redelivery by Gatherer at the Delivery Points on such Gathering System, less System Fuel and Losses, during the then subsequent Month by 11:30 A.M. (CPT) on the first Business Day prior to the earliest deadline for first-of-the-Month nominations of the Receiving Transporters. After the deadline set forth herein, Gatherer shall accept nominations from Producers for first-of-the-Month deliveries subject to Gatherer’s ability, through reasonable efforts, to notify the applicable Receiving Transporter of such untimely nomination and such Receiving Transporter’s confirmation of such untimely nomination.

(b) Changes to First-of-the-Month Nominations. Producers shall submit changes to its first-of-the-month nominations in writing to Gatherer, by facsimile or email, as set forth in Section 1(a) above, no later than 11:30 a.m. (CPT) one Business Day prior to the scheduled Day of flow. Subject to acceptance and confirmation by the Receiving Transporter, such revised nominations shall be effective for the remainder of the Month unless later changes are made in accordance with this Exhibit D. After this deadline, Gatherer shall accept such nomination changes from the Producers, subject to Gatherer’s ability, through reasonable efforts, to notify the applicable Receiving Transporter of such untimely nomination and such Receiving Transporter’s confirmation of such untimely nomination.

(c) Nomination Confirmations. Upon receipt of Producers’ timely nomination, Gatherer shall review said nomination and promptly notify Producers should a discrepancy exist between Producers’ nominated volumes and volumes confirmed by the Receiving Transporters for Producers at the applicable Delivery Points. If it is determined that Producers are responsible for the discrepancy, it shall be the Producers’ responsibility to correct the discrepancy and timely re-nominate the corrected volumes. If the discrepancy is not resolved, the “corrected volumes” will be considered the lesser of the volume nominated by Producers at the applicable Delivery Points or the volume confirmed by the Receiving Transporters. Gatherer shall notify Producers in writing, by facsimile or email, of the confirmed nomination on the Gathering System for first-of-the-Month nominations or changes thereto. Gatherer shall not be obligated to provide service hereunder on any Day that Producers do not nominate under the procedures herein or of the Receiving Transporters. Any waiver by Gatherer of the provisions of this Section 1(c) shall not constitute a waiver of Gatherer’s future rights under this Section 1.

(d) Producers’ Obligation to Maintain Balance. Producers shall manage receipts and deliveries of Producers’ Gas and MV Mitigation Gas and, if necessary, make adjustments to

maintain a balance of receipts and deliveries. Producers shall manage receipts and deliveries so that the Imbalance shall be kept as near zero as practicable. “Imbalance” shall be defined as the difference between the quantity (expressed in MMBtu’s) of Producers’ Gas and MV Mitigation Gas received at the Receipt Points on a Gathering System on any Day, after deducting Producers’ allocated share of System Fuel and Losses, and the quantity (expressed in MMBtu’s) of Producers’ Gas and MV Mitigation Gas delivered to the Delivery Points on such Gathering System on such Day.

(e) Gatherer’s Right to Minimize Variances and to Balance. Unless agreed between the Parties, Gatherer shall not be required to receive quantities from Producers in excess of the quantities of Producers’ Gas and MV Mitigation Gas the Receiving Transporters will accept at the Delivery Points on a concurrent basis. Gatherer shall have the right, in its sole discretion, to amend receipts or deliveries of Producers’ Gas and/or MV Mitigation Gas 24 hours after Notice to Producers if Producers fail to provide evidence to Gatherer’s satisfaction that within such 24 hour period it has commenced a good faith effort to eliminate any existing Imbalance within a reasonable time.

(f) Imbalance Resolution. Gatherer and Producers shall keep accurate records of the quantities of Producers’ Gas and MV Mitigation Gas nominated, confirmed, allocated, and redelivered from the Receipt Points to the Delivery Points and any Imbalance related thereto. Monthly imbalances shall be added/subtracted to/from the cumulative imbalance from the previous Month and the newly calculated Imbalance position will be considered in the subsequent months’ nominations to bring said Imbalance position as close to zero as practicable.

(g) Receipt Allocations. If Producers’ Gas or MV Mitigation Gas is commingled with other gas at a Receipt Point, the allocation of Gas at each Receipt Point shall be based upon each Producers’ marketing percentage as defined by the operator of that Receipt Point.

(h) Curtailment Procedures. If Gatherer determines on any Day that for any reason whatsoever, including Force Majeure Events and periods of normal and routine maintenance, that confirmed nominations exceed the Gathering System’s available capacity at any area or point, Gatherer shall, without liability to Producers, curtail or interrupt deliveries of all Gas in such area or point as provided in the Agreement, determined by confirmed nominations for all Gas gathered in such area or point. In instances where gathering of Producers’ Gas and/or MV Mitigation Gas is interrupted and Gatherer has provided Producers Notice thereof, Producers shall notify the applicable Receiving Transporters of any modification to the confirmed nominations at the applicable Delivery Points. In the event of a curtailment described herein, the applicable Fees shall apply only to Producers’ Gas and MV Mitigation Gas received by Gatherer at the affected Receipt Points (expressed in Mcf’s).

(i) Operational Control. Gatherer shall retain full operational control of the Gathering Systems and shall at all times be entitled to schedule deliveries and to operate its facilities in a manner which, in Gatherer’s judgment, is consistent with the obligations and operating conditions, inclusive of normal and routine maintenance, as may exist from time to time on the Gathering Systems or which will allow Gatherer to optimize the use of the Gathering Systems consistent with the terms of this Agreement. Gatherer’s performance shall be excused, in full or in part, during periods of Force Majeure Events and normal and routine maintenance.

(j) Coordination with Receiving Transporters. The Parties recognize that Gatherer must coordinate its actions with those of the Receiving Transporters. Accordingly, upon 30 Days Notice to Producers, Gatherer may modify provisions of this Agreement to implement standards promulgated by the National Association of Energy Standards Board adopted by any Receiving Transporter as it relates to a Gathering System or to otherwise coordinate the provisions of this Agreement with the operating conditions, rules, or tariffs of the Receiving Transporters.

(a) Practices. All Producers’ Wellhead Meters and Gatherer’s Receipt Meters shall be constructed, installed, and operated in accordance with the following standards depending on the type of meters used.

(1) Orifice Meters - In accordance with ANSI/API 14.3.2 (American Gas Association Report No. 3), Orifice Metering of Natural Gas and Other Hydrocarbon Fluids, Fourth Edition, dated April 2000, and any subsequent amendments, revisions or modifications thereof and shall include the use of flange connections.

(2) Positive Meters - In accordance with the American Gas Association Measurement Committee Report No. 6 (American Gas Association Report No. 6) dated January 1971, and any subsequent amendments, revisions or modifications thereof.

(3) Turbine Meters - In accordance with the American Gas Association Measurement Committee Report No. 7 (American Gas Association Report No. 7), First Revision, dated November 1984, and any subsequent amendments, revisions or modifications thereof.

(4) Electronic Transducers and Flow Computers - in accordance with the applicable standards of the American Petroleum Institute, including but not limited to API No. 21.1, and any subsequent amendments, revisions, or modification thereof.

(5) Ultrasonic Meters - In accordance with the American Gas Association Measurement Committee Report No. 9 (American Gas Association Report No. 9), dated June 1998, and any subsequent amendments, revisions or modifications thereof.

(6) Coriolis Meters - In accordance with American Gas Association Report No. 11, and any subsequent amendments, revisions, or modifications, thereof.

Notwithstanding anything contained in this Exhibit to the contrary, Gatherer shall not be required to replace or make any alterations to its measuring equipment as a result of any subsequent amendments, revisions, or modifications of the American Gas Association Reports cited in Subparagraphs (1) through (6) of this Section 2(a), unless the Parties mutually agree to such replacement or alteration.

(b) Testing. Gatherer shall give reasonable Notice to Producers of any cleaning, changing, repairing, inspecting, testing, calibrating, or adjusting of Gatherer’s Receipt Meters or Producer’s Wellhead Meters or the measuring equipment at the Delivery Points to permit

Producers to have a representative present. The official charts (recordings) from the measuring equipment shall remain the property of Gatherer. Upon request, Gatherer will submit its records and charts, together with calculations therefrom, to Producers for inspection and verification, subject to return to Gatherer or its designee within 30 Days after receipt thereof.

(c) Accuracy of Meters. All Producers’ Wellhead Meters and Gatherer’s Receipt Meters shall be verified (and calibrated) at the following intervals: (i) if the deliveries of Gas through the meter average less than 100 Mcf/d, at least once each Year, (ii) if the deliveries of Gas through the meter average between 100 Mcf/d and 500 Mcf/d, at least once each 6 Months, (iii) if the deliveries of Gas through the meter average between 500 Mcf/d and 5,000 Mcf/d, at least once each 3 Months, (iv) if the deliveries of Gas through the meter average more than 5,000 Mcf/d, at least 12 times per Year with no longer than 45 Days between each meter verification and calibration. Meters located on land managed by the Bureau of Land Management will be verified at least once each calendar quarter by Gatherer. If, upon any test, the measuring equipment is found to be inaccurate by 2% or less, previous readings of such equipment will be considered correct in computing the deliveries of Producers’ Gas and MV Mitigation Gas hereunder, but such equipment shall immediately be adjusted to record accurately. If, upon any test, the measuring equipment is found to be inaccurate by more than 2% of the average flow rate since the last test, then any previous recordings of such equipment shall be corrected to zero (0) error for any period which is known definitely or agreed upon, using the procedure set forth in Section 1(d) below. If such period is not known or agreed upon, such correction shall be made for a period covering 1/2 of the time elapsed since the date of the latest test, but not to exceed 16 Days when the equipment is tested every Month and not to exceed 45 Days when the equipment is tested every 3 months. If Producers desire a special test of any measuring equipment, then at least 72 hours advance Notice shall be given to Gatherer by Producers, and both Parties shall cooperate to secure a prompt test of the accuracy of such equipment. If the measuring equipment so tested is found to be inaccurate by 2% or less, Gatherer shall have the right to bill Producers for the costs incurred due to such special test, including any labor and transportation costs and Producers shall pay such costs promptly upon invoice thereof.

(d) Adjustments. If, for any reason, any measurement equipment is out of adjustment, out of service, or out of repair and the total calculated hourly flow rate through each meter run is found to be in error by an amount of the magnitude described in Section 2(c), the total quantity of Producers’ Gas and MV Mitigation Gas delivered shall be redetermined in accordance with the first of the following methods which is feasible:

(1) by using the registration of any check meters, if installed and accurately registering (subject to testing as described in Section 2(c)), or

(2) where parallel multiple meter runs exist, by calculation using the registration of such parallel meter runs; provided that they are measuring Producers’ Gas and MV Mitigation Gas from upstream headers in common with the faulty metering equipment, are not controlled by separate regulators, and are accurately registering; or

(3) by correcting the error by rereading of the official charts, or by straightforward application of a correcting factor to the quantities recorded for the period (if the net percentage of error is ascertainable by calibration, tests or mathematical calculation); or

(4) by estimating the quantity, based upon deliveries made during periods of similar conditions when the meter was registering accurately.

(e) Meter Records Retention. Gatherer shall retain and preserve for a period of at least 6 years all test data, charts, and other similar records.

(f) Nonuse of Receipt Point. If Producers have failed to nominate Producers’ Gas or MV Mitigation Gas for delivery at a Receipt Point for 3 consecutive Months, Gatherer shall have the right, at any time thereafter, to Notify Producers of such nonuse. Upon receipt of such nonuse Notice, Producers shall promptly provide Notice to Gatherer whether they intend to resume deliveries of Producers’ Gas or MV Mitigation Gas at such Receipt Point and the date by which such deliveries will resume. If Producers fail to provide such Notice or Notify Gatherer that they do not intend to resume deliveries of Producers’ Gas or MV Mitigation Gas at such Receipt Point, then Gatherer will have the right to disconnect the pad level custody transfer meter at such Receipt Point (or, if Gatherer has not installed a pad level custody meter at such Receipt Point, to disconnect Producers’ Wellhead Meter at such Receipt Point).

(g) Performance by Producers. Gatherer shall have the right to request that Producers or its designee(s) provide the services necessary to read, test, calibrate, and adjust Producers’ Wellhead Meters and Gatherer’s Receipt Meters on behalf Gatherer hereunder. Upon Notice by Gatherer to Producers to perform such services for any of Producers’ Wellhead Meters or Gatherer’s Receipt Meters, Producers or its designee(s) shall commence performing such services as soon as reasonably practicable. Such services shall be performed by Producers or its designee(s) for Gatherer at a reasonable allocated cost for the actual, recorded time spent by the employees of Producers or its designee(s) performing such services.

(h) Pulsation. If Gas pulsation problems occur upstream of the Barnett Receipt Points, Producers, or their designee, shall take the reasonable and customary industry adopted steps necessary to mitigate such pulsation. If Gas pulsation occurs downstream of the Barnett Receipt Points, Gatherer, or its designee, shall take the reasonable and customary industry adopted steps necessary to mitigate such pulsation.

(a) Units. The unit of volume for measurement shall be one (1) Cubic Foot. Such measured volumes shall be multiplied by their Gross Heating Value per Cubic Foot and divided by 1,000,000 to determine MMBtu’s delivered hereunder.

(b) Temperature. The temperature of Producers’ Gas and MV Mitigation Gas shall be determined by a recording thermometer installed so that it may record the temperature of Producers’ Gas and MV Mitigation Gas flowing through the meters, or such other means of recording temperature as may be mutually agreed upon by the Parties. The average of the record to the nearest one degree Fahrenheit (1°F), obtained while Producers’ Gas and MV Mitigation Gas is being delivered, shall be the applicable flowing Gas temperature for the period under consideration.

(c) Specific Gravity. The specific gravity of Producers’ Gas and MV Mitigation Gas shall be determined by a recording gravitometer or chromatographic device installed and located at a suitable point to record representative specific gravity of Gas being metered or, at Gatherer’s option, by spot samples or continuous sampling using standard type gravity methods. If a recording gravitometer or chromatographic device is used, the gravity to the nearest one-thousandth (0.001) obtained while Producers’ Gas and MV Mitigation Gas is being delivered shall be the specific gravity of the Gas used for the recording period. If the spot sample or continuous sampling method is used, the gravity shall be determined to the nearest one-thousandth (0.001). Spot sampling shall be determined at the same frequency as Gross Heating Value is determined pursuant to Section 3(f), below. The result should be applied during such Month for the determination of Producers’ Gas and MV Mitigation Gas volumes delivered.

(d) Supercompressibility. Adjustments to measured Gas volumes for the effects of supercompressibility shall be made in accordance with accepted American Gas Association standards. Gatherer shall obtain appropriate carbon dioxide and nitrogen mole fraction values for Producers’ Gas and MV Mitigation Gas delivered as may be required to compute such adjustments in accordance with standard testing procedures. At Gatherer’s option, equations for the calculation of supercompressibility may be taken from either the American Gas Association Manual for the Determination of Supercompressibility Factors for Natural Gas, dated December, 1962 (also known as the “NX-19 Manual”) or the American Gas Association Report No. 8, dated December 1985, Compressibility and Supercompressibility for Natural Gas and Other Hydrocarbon Gases, latest revision.

(e) Pressure. For purposes of measurement and meter calibration, the atmospheric pressure for each of the Receipt Points and Delivery Points shall be assumed to be the pressure value determined by Gatherer, or its designee, for the county elevation in which such point is located under generally accepted industry practices irrespective of the actual atmospheric pressure at such points from time to time. For the purposes herein, such atmospheric pressure will be assumed to be 14.65 pounds per square inch absolute.

(f) Gross Heating Value. The Gross Heating Value of the Gas delivered at the Receipt Points and Delivery Points shall be determined using the following schedule: (i) if the deliveries of Gas through the meter average less than 100 Mcf/d, at least once each Year, (ii) if the deliveries of Gas through the meter average between 100 Mcf/d and 500 Mcf/d, at least once each 6 Months, (iii) if the deliveries of Gas through the meter average between 500 Mcf/d and 5,000 Mcf/d, at least once each 3 Months, (iv) if the deliveries of Gas through the meter average more than 5,000 Mcf/d, at least 12 times per Year with no longer than 45 Days between each test, by means of some approved method of general use in the Gas industry.

(g) Quality Specifications. Determination of the Gross Heating Value, relative density and compressibility at the Receipt Points and Delivery Points will be made using the following standards (as amended from time to time by the relevant professional association):

(1) Gas Processors Association (GPA) 2166 - Obtaining Natural Gas Samples for Analysis of Gas.

(2) Gas Processors Association (GPA) 2261 – Analysis for Natural Gas and Similar Gaseous Mixtures by Gas Chromatography.

(3) Gas Processors Association (GPA) 2145 – Physical Constants for paraffin Hydrocarbons and Other Components of Natural Gas.

(4) Gas Processors Association (GPA) 2172 – Calculation of Gross Heating Value, Relative Density, and Compressibility of Natural Gas Mixtures from Compositional Analysis.

(h) Other Contaminants. Other tests to determine water content, sulfur, hydrogen sulfide, inert gases, and other impurities in Producers’ Gas and MV Mitigation Gas shall be conducted whenever requested by either Party and shall be conducted in accordance with standard industry testing procedures.

(i) New Test Methods. If a new method or technique is developed with respect to Gas measurement or the determination of the factors used in such Gas measurement, then such new method or technique may be substituted for a method set forth in this Section 3 when such methods or techniques are in accordance with the currently accepted standards of the American Gas Association if mutually agreed to by the Parties.

4. Barnett Central Gathering System. The following terms shall apply to the calculation of the Barnett Fees on the Barnett Central Gathering System.

(a) Gatherer shall invoice Producers for Producers’ Gas and MV Mitigation Gas received each Month at the Barnett Receipt Points on the Barnett Central Gathering System based on the Barnett Fees shown in Section 1 above

(b) The following delivery points on the Barnett Central Gathering System are covered by the [Party A] Agreement dated September 1, 2007, between CEMI and [Party A] (“[Party A]”), as amended (the “[Party A] Agreement”) are identified below, and such delivery points (together with any other mutually agreeable future delivery points on the Barnett Central Gathering that the Parties designate as such) shall be referred to herein as the “Barnett Central [Party A] Delivery Points”:

(c) If (i) [Party A] curtails or suspends services at the Barnett Central [Party A] Delivery Points, including the occurrence of a force majeure event or similar interruption affecting [Party A], (ii) Producers or the Total Parties reduce the contracted volumes of Gas or actual volumes of Gas delivered under the [Party A] Agreement, or (iii) the pressures at any Barnett Central [Party A] Delivery Point increase as the result of changes by [Party A] in any Month and (as to each of clause (i), (ii) and (iii) preceding) any such event (or combination of such events) causes or results in a change in the distribution of the volume weighted average monthly Barnett Fee pressure tiers in Section 1 above for the Barnett Receipt Points on the Barnett Central Gathering System resulting in lower revenues to Gatherer from such Barnett Receipt Points for such Month, then such event is referred to herein as a “[Party A] Event.”

(d) During any Month when a [Party A] Event occurs or is in effect, the Barnett Fees for each Barnett Receipt Point on the Barnett Central Gathering System for such Month shall be calculated using the Barnett Fee pressure tier that applied to such Barnett Receipt Point during the most recent Month preceding such [Party A] Event in which a [Party A] Event did not occur.

(e) The provisions of this Section 4 of Schedule A2 shall apply to any replacements of the [Party A] Agreement, whether with [Party A], its successors, or other Person providing low pressure service.

(f) An illustrative calculation of the volume weighted average monthly Barnett Fee pressure tiers under clause (c) above is shown below.

Note: Upon any termination of Gatherer’s agency designation or the O&M Terms under 12.14, the Adjusted Barnett Annual Minimum Volume would be adjusted pursuant to Section 4(d) of Exhibit A. Adjusted Barnett Annual Minimum Volume may be increased in the last year for any MVC Additional Volume Wells Amount under 5(b)(6).

Methodology applied to any Barnett Delayed Connection Volume and Force Majeure Volume

(1) In the event of a Barnett Delayed Connection, Adjusted Barnett Annual Minimum Volume decreased during period of delay based on Barnett Type Curve. Adjustment based on Barnett Type Curve to include period from target Completion Date to end of Minimum Volume Period.

(2) Upon actual connection, Adjusted Barnett Annual Minimum Volume increased based on Barnett Type Curve. Adjustment based on Barnett Type Curve to include period from actual connection to end of Minimum Volume Period.

(3) In each year, net impact of (1) and (2) above is increase / decrease to Adjusted Barnett Annual Minimum Volume. At end of Minimum Volume Period, any remaining volume attributable to the Barnett Annual Minimum Volume over the Minimum Volume Period is accumulated in the final period of the Minimum Volume Period. In no event should total volume adjustments reduce the nominal Barnett Minimum Volume.

Note: Illustrative example only to show application of additional fee.
Step 1	-	Calculate the volume operating in each tier each month.
Step 2	-	Convert volumes into a percentage operating within each tier - MMCF %.
Step 3	-	Occurrence of a “[Party A] Event”.
Step 4	-	Compare the percentages (MMCF %) before the occurrence of a “[Party A] Event” with those after the event.
Step 5	-	Calculate revenue impairment to gatherer by multiplying MMCF % by appropriate Fees in both months.
Step 6	-	If revenue impairment is confirmed, the weighted average Fee will be adjusted to the Fee for the most recent Month preceding such [Party A] Event in which a [Party A] Event did not occur.
Step 7	-	The difference in the weighted average Fee will be applied to each tier.
