5.3 Remedies for Failure to Meet Milestone Completion Dates. In the event that Gatherer fails to meet a Milestone Completion Date in the absence of Force Majeure, Shipper shall be entitled to the cumulative remedies set forth in Sections 5.3(a) and (b) below:

(a) For each Day that Shipper is prevented from delivering any Gas to the Olympia Gathering System, Shipper shall, in addition to the remedies provided for in Section 5.3(b) below, be entitled to one (1) Day of Gathering service without paying the associated Gathering Fee then in effect for such well or wells impacted as a result of the failure to meet the applicable Milestone Completion Date, beginning with the first delivery of Gas from the well or wells, with such Days of Gathering service without paying the associated Gathering Fee not to exceed ninety (90) Days of Gathering service for such well or wells, and,

(b) Subject to the provisions of Section 18.1, Shipper may, but shall not be obligated to, elect to complete construction of those portions of the Olympia Gathering System for which Gatherer has not met an applicable Milestone Completion Date at Shipper’s sole cost and expense and elect to either: (1) retain ownership of such constructed facilities, in which case Gatherer shall provide necessary access and cooperate with Shipper to facilitate the construction and operation of such facilities, provided that to the extent Shipper retains ownership, Gatherer shall be compensated by Shipper for the actual cost of constructing the relevant portions of the Olympia Gathering System through the date such election is exercised, or, (ii) convey ownership of such constructed facilities to Gatherer and recover from Gatherer the actual costs to construct the facilities (including but not limited cost of equipment and labor).

5.4 Construction Plans. Upon acceptance by Gatherer and the Preferential Capacity Shippers of the schematics, plans and time periods identified on Exhibit D and the Initial Build Conditions, or the applicable schematics, plans, time periods and specifications for any new facilities excluding the Receipt Points, which are provided for in Section 5.6 (collectively the “Construction Plan(s)”) to be constructed pursuant to this Agreement, Gatherer will proceed with the applicable Construction Plan in a good and workmanlike manner, consistent with prudent industry practices, customary engineering practices, to Gatherer’s specifications and in compliance with the Initial Build Conditions and all applicable laws, rules and regulations of all governmental authorities having jurisdiction. Furthermore, Gatherer will use its best efforts to complete the work under any applicable Construction Plans in accordance with the mutually agreeable timelines provided therein (including the Expansion Completion Deadlines provided for in Exhibit E). Such Construction plans for Expansion Capacity or new facilities shall also have mutually agreeable Milestone Completion Dates similar to those described in Section 5.2 above, and the remedies under Sections 5.3 and 11 (b) shall apply, as applicable, to such Expansions or new facilities.

5.5 Periodic Planning Meetings. The Parties and Shipper Partner shall meet no less often than monthly to: (i) discuss Shippers drilling plans, (ii) review the progress of construction, (iii) review Shipper’s good faith production forecasts, (iv) review the facility requirements, including potential Receipt Points, for the Olympia Gathering System and any required or desirable changes in the design scope; (v) any changes to the construction performance and operations performance as per the requirements and timelines agreed upon as part of this Agreement; and (vi) any other matters concerning the Parties’ performance under the Agreement. Gatherer will make available on a monthly basis, in addition to the daily readings Shipper can access on Gatherers operational data acquisition system, a report detailing operational data as decided upon by the Parties during the initial and on-going weekly planning meetings as provided in this Section 5.5. The purpose of these meetings is to provide meaningful communication and advance planning for facilities on the Olympia Gathering System. The Parties shall each designate a representative to participate in the Parties weekly planning meetings and serve as a single point of contact for all planning, operations and coordination aspects of this Agreement.

5.6 Method of Selecting Receipt Points and Construction of Initial Build Laterals. At any time during the Term, either of the Preferential Capacity Shippers may designate a Receipt Point up to the collective number of Receipt Points identified on Exhibit C in the governmental sections within the Committed Area from which Gatherer will receive Shipper Gas (“Receipt Points”). Upon Gatherer’s receipt of such Preferential Capacity Shipper’s written notice designating such Receipt Points and the designated operator of such Receipt Points (the “Receipt Point Notice”), Gatherer shall commence and diligently acquire the necessary rights-of-way and permits in order to construct the lateral Gathering pipelines to connect the designated Receipt Points (the “Initial Build Laterals” as further defined in the General Terms and Conditions) and will use its best efforts to have the applicable Receipt Point and Initial Build Lateral operational and ready to receive Gas (the “Service Date”) on the date that is ninety (90) days from Gatherer’s receipt of such Preferential Capacity Shipper’s notice If Gatherer is unable to complete the Receipt Point by the Service Date, then the provisions of Section 5.3 (a) and (b) are applicable to the Receipt Point and Initial Build Laterals in accordance with Exhibit D. Gatherer and the Preferential Capacity Shippers have agreed the initial Build Laterals that extend off the Core Lines consist of 6” pipelines. The Initial Build Laterals include a total of 62 miles of six-inch diameter pipeline as detailed in Exhibits B and C. Anytime on or before May 1, 2011, the Preferential Capacity Shippers may elect to utilize up to 62 miles of six-inch diameter pipe in an alternate fashion than as that initially designed, as long as the total mileage of six inch pipe used by the Preferential Capacity Shippers collectively does not exceed 62 miles. The 62 miles of six-inch diameter pipeline maximum is exclusive of: (i) Red River bores; (ii) city limit pipelines assuming designated Receipt Point locations are within a city limit; and (iii) any laterals, Trunk Lines, flow lines and facilities required under Section 6 of this Agreement and (iv) any laterals, Trunk Lines, flow lines and facilities required under Section 7 of this Agreement If more than 62 miles of six-inch diameter pipelines are required by the Preferential Capacity Shippers for Initial Build Laterals, then such laterals will be completed under the provisions provided in Section 7.

5.7 Interconnections as part of Initial Build. The Parties acknowledge that part of the assets acquired pursuant to the PSA include six existing Interconnections as described on Exhibit I. Gatherer will (i) redeliver Shipper Gas produced from wells to those existing Interconnections and (ii) construct at Gatherer’s cost for Preferential Capacity Shippers the following additional Interconnections:

Additionally, if Gatherer has not spent at least $4,500,000.00 in constructing the above Haynesville Extension Interconnection, then the difference between $4,500,000.00 and the cost to Gatherer of constructing the Haynesville Extension Interconnection will be available for the construction of additional Interconnections as designated by Shipper and

Shipper Partner, collectively, in writing to Gatherer. The location of the points of Interconnection shall be subject to Gatherer’s sole discretion, reasonably exercised. These new Interconnections shall be constructed as part of the Initial Build For purposes of clarification and avoidance of doubt, notwithstanding the foregoing, Shipper Gas may be re-delivered to any Redelivery Point as nominated by Shipper up to the Interconnection’s stated capacity in accordance with the terms and conditions of this Agreement. Each of the Interconnections referenced above are designed to accommodate a capacity of at least 250 MMcf per Day except for the Robeline Interconnection into Tennessee Gas Pipeline Company, which will have a capacity of at least 550 MMcf per Day. Gatherer will so construct or arrange the Plants to provide for future Interconnections to reduce potential downtime.

5.8 Power In-Service Date for Olympia Gathering System. Gatherer shall use reasonable efforts to acquire commercial power for the Plants as soon as reasonably possible following the Effective Date. If after one ( I) year from the Effective Date the applicable commercial power company does not provide power or Gatherer determines that it is not economically feasible for Gatherer to purchase such power, then Gatherer shall bear the costs associated with the actual fuel required to operate the generators after such date.

5.9 Preferential Capacity. Shipper Partner and Shipper (Shipper Partner and Shipper shall collectively be referred to as “Preferential Capacity Shippers”) shall collectively have the exclusive preferential right over all third parties to the complete and total available capacity up to the treating capacity as defined in Exhibit C as provided herein, including, without limitation, blending capacity, of the Olympia Gathering System (inclusive of the Treating Plants, for the avoidance of doubt) in complete preference to and without any shared or proportional decrease in the Preferential Capacity Shippers’ Gas with any other shipper on the Olympia Gathering System (inclusive of the Treating Plants, for the avoidance of doubt) in event of Force Majeure, Plant Maintenance or other partial or full curtailment (the “Preferential Capacity”). Gatherer shall be entitled to use any portion of the Preferential Capacity, on an interruptible basis, not necessary for the receipt and Treatment of the Preferential Capacity Shipper’s Gas, without restriction or obligation to the Preferential Capacity Shippers other than to provide the Preferential Capacity Shippers with the Preferential Capacity, Preferential Capacity shall be allocated between Preferential Capacity Shippers on a pro rata basis based on the applicable Annual Volume Commitment of the Preferential Capacity Shippers. Initially, there shall be only two Preferential Capacity Shippers on the Olympia Gathering System—Shipper and Shipper Partner; provided, however, in the event that Shipper assigns less than all its interest in this Agreement to a third party, then Shipper shall be entitled, at its election, to apportion all, some or none of the applicable Volume Commitment and/or Preferential Capacity between Shipper and its assignee. Upon apportionment of all or some Preferential Capacity to an assignee of Shipper, such assignee shall become a Preferential Capacity Shipper.

5.10 Multi-line Rights of Way. Gatherer will use its reasonable efforts to obtain multi-line and multi-use rights of way where possible In the event multi-line rights are obtained by Gatherer, Shipper may request the assignment of the right to construct and operate one or more pipelines pursuant to such multi-line rights. Gatherer shall consent to such request for assignment by Shipper, unless such assignment would adversely affect Gatherer’s future plans and anticipated needs in order to provide service under this Agreement Gatherer shall consider a

request for assignment by Shipper in good faith based on Gatherer’s future plans and anticipated needs, but Gatherer in its sole discretion shall determine whether to comply with such request for assignment In the event Gatherer has the authority to do so and grants to Shipper the right to construct and operate one or more additional pipelines pursuant to the multi-line rights, such pipeline(s) shall be constructed and operated (i) at the sole risk and expense of Shipper, (ii) pursuant to spacing specifications and requirements of Gatherer, (iii) at a location and within a specific area, approved in writing by Gatherer, and (iv) so as not to interfere with Gatherer’s operations.

6.1 Expansion Capacity Request. During the first five years of the Term, and upon written notice from Shipper (each notice being an “Expansion Capacity Request”) for an expansion of the capacity of the Olympia Gathering System (“Expansion Capacity”), Gatherer shall expand the Olympia Gathering System under the terms of this Section 6. Within the time periods provided on the attached Exhibit E, Gatherer shall commence and acquire the necessary rights-of-way and permits, and execute until complete, construction of Gathering lines, including necessary laterals, facilities and Plants necessary to increase the capacity of the Olympia Gathering System (which, for the avoidance of doubt, is inclusive of the Initial Build Laterals) in minimum increments stated on Exhibit F up to a maximum additional capacity of 520 MMcf per Day. The Expansion Capacity Request will specify Shipper’s requested additional capacity increase amount (in the MMcf per Day increments) and the location in the Committed Area, if any, the Shipper is requesting Gatherer to expand. Shipper may elect more than one per Day increment at any one time The Gathering Fee for all Gas delivered and Gathered through the Olympia Gathering System shall adjust upon the in service date of Expansion Capacity, as specified in the attached Exhibit F (the “Revised Gathering Fee”). Shipper and Shipper Partner may make joint or separate Expansion Capacity Requests as long as the total capacity request meets the applicable per Day increment requirements for Expansion Capacity. Furthermore, in the event of an Expansion Capacity Request, then the provisions of Section 6.2 below shall apply with respect to both Shipper and Shipper Partner, regardless of whether Shipper or Shipper Partner makes an Expansion Capacity Request.

6.2 Gathering Fees Associated with Expansion Capacity. Gathering Fees as a result of Expansion Capacity Requests occurring in the first five years after the Effective Date and up to a total of 1,100 MMcf per Day shall be calculated pursuant to Exhibit F. The Revised Gathering Fees that result from any Expansion will remain subject to the annual escalation, if applicable, and all other provisions herein which may further change the Gathering Fee from time-to-time. Detailed examples of how the Revised Gathering Fee is calculated with different expansion elections is illustrated in Exhibit F. Notwithstanding the above, in no event shall the Gathering Fee for the term of the Agreement exceed [***] or be less than [***] excluding adjustments to the Gathering Fee that result from operation of the following provisions in the Gathering and Treating Agreement: Subsection 4.2 (Annual Escalation), Subsection 9.2 (Annual Volume Commitments), Subsection 10 (Favored Nations), and Subsection 8.1(c) (Pressure), Section 6 (Expansion Capacity), and Section 7 (Additional Services). The Base Fees listed on Exhibit F are based upon specific design conditions and assumptions such as the time of construction, facilities, location of the facilities, flow rate, ratable volumes, etc. A copy of these design conditions/assumptions are found on Exhibit C and Exhibit D to this Agreement.

6.3 Expansion Capacity Annual Volume Commitment. Shipper covenants and agrees that during the first ten (10) years from the date of completion of any increment of additional capacity requested by Shipper, in addition to and apart from any Annual Volume Commitment (as defined in Section 9.1) made herein, Shipper will deliver to Gatherer for Gathering from the Committed Area a minimum quantity of Gas each Contract Year equal to the amount of additional incremental capacity requested pursuant to an Expansion Capacity Request (an “Expansion Capacity Annual Volume Commitment”) (and, to the extent that Shipper delivers an amount of Gas up to the Expansion Capacity Annual Volume Commitment, then that quantity of Gas shall be designated herein as “Incremental Gas” for purposes of Section 9.8) By way of example, if Shipper requests a 100 MMcf per Day expansion of incremental capacity, then the Expansion Capacity Annual Volume Commitment will be: (i) the thermal equivalent in MMBtus of 100 MMcf per Day; times (ii) three hundred sixty-five (365) For purposes of the Expansion Capacity Annual Volume Commitment, the Gross Heating Value of the Gas will be deemed to be nine hundred fifty (950) Btus per cubic foot. Subject to Sections 9.5 and 9.6, in any year that Shipper fails to meet the total of all outstanding Expansion Capacity Annual Volume Commitments for that year (an “Expansion Capacity Volume Shortfall”), Shipper shall at its sole election, (i) remit a payment to Gatherer calculated by multiplying the Expansion Capacity Volume Shortfall for the applicable contract year by the Gathering Fees in effect during the corresponding year (the “Expansion Capacity Volume Shortfall Payment”); or (ii) pay an amount of money, paid in twelve (12) equal monthly installments, equal to the Expansion Capacity Volume Shortfall Payment plus interest at a rate that is the greater of: (X) [***]; or (Y) [***] plus the difference between• (i) the 10 Year U S. Treasury Note Yield Curve Rates (as published in the “Commodities Report” in the Wall Street Journal for each day (the “10 Year Note Yield”)) for the last Business Day of the applicable Contract Year, and (ii) the 10 Year Note Yield as of the Effective Date. Gatherer shall calculate the Expansion Capacity Volume Shortfall and Expansion Capacity Volume Shortfall Payment, if any, within sixty (60) days after the expiration of the Contract Year in which the shortfall occurred, and the results shall be promptly provided in writing to Shipper. Shipper shall remit the Expansion Capacity Volume Shortfall Payment or first Expansion Capacity Volume Shortfall Payment monthly installment, if any, within thirty (30) days of receipt of the invoice containing the Expansion Capacity Volume Shortfall Payment calculation. Subsequent Expansion Capacity Volume Shortfall and Expansion Capacity Volume Shortfall Payment calculations and payments shall be made in the same manner upon expiration of each successive Contract Year.

6.4 Exchange of Information. To the extent permitted by applicable law as well as any contractual limitations with third parties, the Parties will periodically exchange information regarding future utilization of the Olympia Gathering System by Shipper, Shipper Partner and/or Third Party Gas.

7.1 Additional Services. At any time during the Term, Shipper can request that Gatherer provide Additional Services or construct Additional Interconnections under this Agreement. The term “Additional Services” shall mean the provision of additional services or the installation of additional facilities that are not contemplated by Sections 5 and 6 of this Agreement Additional Services may include, but are not limited to, such services or facilities necessary to increase capacity (to the extent not covered in Sections 5 and 6), to reduce pressures

as requested by Shipper, including, without limitation, adding of additional pipe, looping of lines, or additional compression, and any additional Treating, processing services, or Additional Interconnections. The term “Additional Interconnections” shall mean the addition of Interconnections in excess of those contemplated in Section 5.7 of this Agreement

7.2 Notice of Request for Additional Services and Gatherer Proposal. If Shipper desires Additional Services or Additional Interconnections, then Shipper shall deliver written notice to Gatherer that describes the Additional Services or Additional Interconnections requested by Shipper. Within fifteen (15) days of receipt of such notice, or as soon as reasonably possible after Gatherer receives all cost estimates from Interconnecting Pipelines or third parties if such cost estimates are not received within the 15-day period, Gatherer shall submit to Shipper a proposal for such Additional Services or Additional Interconnections and the additional Gathering Fee, if applicable, in connection therewith (the “Additional Services Proposal”) The additional Gathering Fee, if applicable, which shall become effective upon completion of the construction of the Additional Services, shall be calculated based on the following factors (i) the remaining term of the Agreement; (ii) capital expenditures for the Additional Services; and, (iii) the greater of: (X) Gatherer’s [***] internal required rate of return; or (Y) Gatherer’s [***] internal required rate of return plus the difference between: (i) the 10 Year Note Yield on the date of calculation; less (ii) the 10 Year Note Yield as of the Effective Date. An example of this calculation is provided in Exhibit G. Within fifteen (15) days of receipt of the Additional Services Proposal, Shipper shall notify Gatherer in writing either (x) to commence construction for such Additional Services or Additional Interconnections, (y) that Shipper shall construct such Additional Services or Additional Interconnections as provided in Section 7.3 below or (z) that Shipper has elected not to require construction of the requested Additional Services or Additional Interconnections at such time. If Shipper notifies Gatherer to commence construction for such Additional Services or Additional Interconnections, Gatherer and Shipper shall mutually agree on a written build schedule and construction milestones for the Additional Services or Additional Interconnections. Upon such mutual agreement, Gatherer shall commence and acquire the necessary rights-of-way and permits, and execute until complete, construction for such Additional Services or Additional Interconnections, including following the procedures for failure to meet the Milestone Completion Dates as provided for in Section 5.3.

7.3 Shipper Construction of Additional Facilities or Additional Interconnections. In the event that Shipper elects the option set forth in Section 7.2(y) above, then Shipper shall complete the construction for such Additional Services or Additional Interconnections at its sole cost and expense, in which case Shipper shall either (i) own those facilities so constructed by Shipper and Gatherer shall provide necessary access and cooperate with Shipper to facilitate the construction and operation of such facilities or (ii) subject to Gatherer’s approval at Gatherer’s sole discretion, convey ownership and operatorship of such Additional Facilities or Additional Interconnections to Gatherer and recover from Gatherer the actual costs to construct such facilities (including but not limited to cost of equipment and labor).

8.1 Pressure Requirements. Gatherer shall maintain the following daily pressure requirements on the Olympia Gathering System (collectively, the “Pressure Requirements”).

(a) The daily average pressure at any individual Receipt Point shall not exceed 1,100 psig (the “Maximum Pressure”).

(b) The daily average pressure at all Receipt Points shall not exceed 975 psig (“Average Pressure”).

(c) Reduction in Gathering Fees for Failure to Comply With Pressure Requirements During the Primary Term. In the event that any of the Pressure Requirements are exceeded for any reason other than (1) Force Majeure, (ii) Plant Maintenance (but not any other maintenance) and/or (iii) the delivery of volumes by Shipper which cause hydraulic constraints pursuant to the provisions of Section 8.4 below, then the Gathering Fees shall be reduced as follows^. (i) in the event that the average daily pressure at any Receipt Point exceeds the Maximum Pressure for a cumulative fifteen (15) days in any Contract Year, the Gathering Fee then in effect shall be reduced by [***] per MMBtu with respect to the volume of Shipper Gas delivered to the particular Receipt Point during the applicable year; and, (ii) in the event that the average daily pressure at all Receipt Points exceeds the Average Pressure for a cumulative fifteen (15) days in any Contract Year, the Gathering Fee then in effect shall be reduced by [***] per MMBtu with respect to the volume of Shipper Gas delivered to all Receipt Points during the applicable year. If both preceding Gathering Fee reductions (1) and (ii) apply, only the greater of the two potential Gathering Fee reductions will apply. Within thirty (30) Days of the end of the applicable Contract Year, Gatherer will refund to Shipper the amount due pursuant to the applicable fee reduction.

8.2 Relief from Pressure Requirements. The Parties agree to waive the Pressure Requirements during the time the compression facilities described on Exhibit C are being installed and made operational in accordance with the schedule attached on Exhibit D during which time the average daily pressure at any Receipt Point shall not exceed 1,325 psig. Notwithstanding the foregoing, the waiver of the Pressure Requirements will not otherwise relieve the Parties of the obligations under this Agreement, including, without limitation, the obligation to meet the Gathering System Completion Date or the Milestone Completion Dates.

8.3 Permanent Release of Shipper Gas for Failure to Comply with the Pressure Requirements. If the daily average pressure at any Receipt Point exceeds the Pressure Requirements applicable to such Receipt Point (and Gatherer is not otherwise relieved of the obligation to maintain the Pressure Requirements pursuant to Section 8.2) for any thirty (30) consecutive Day period, and such excess pressure persists after notice to Gatherer and the opportunity for Gatherer to cure the same within a commercially reasonable time, then Shipper shall have the right (but not the obligation) to notify Gatherer in writing of its intent to immediately and permanently release from the Dedication any or all volumes of Shipper Gas delivered through the Receipt Points at which Gatherer was unable to comply with the Pressure Requirements for a period of thirty (30) consecutive Days. If the daily average pressure at all of the Receipt Points exceeds the Pressure Requirements (and Gatherer is not otherwise relieved of the obligation to maintain the Pressure Requirements pursuant to Section 8.2) and such excess pressure persists after notice to Gatherer and the opportunity for Gatherer to cure the same, then Shipper shall have the right (but not the obligation) to notify Gatherer in writing of its intent to terminate this Agreement, which termination shall become effective thirty (30) Days from the date of such notice.

8.4 Relief From Pressure Requirements Due To Hydraulic Constraints. Gatherer and Shipper have mutually agreed to the size of the Trunk Lines, Core Lines, and Initial Build Laterals. In the event that delivery of volumes by Shipper causes hydraulic constraints that prevent Gatherer from complying with the Pressure Requirements, then all Receipt Points affected by such constraints will be excluded from the Pressure Requirements until such time as such constraints no longer occur. Gatherer will notify Shipper within a reasonable time with a list of the Receipt Points that are affected by such constraints. Shipper may request Gatherer to remedy the hydraulic constraints, in which such remedies would comply with the terms and provisions of Section 7 of this Agreement.

9.1 Volume Commitments. During the first ten (10) years of this Agreement, Shipper will deliver to Gatherer for Gathering from the Committed Area the following minimum quantities of Gas each year (each an “Annual Volume Commitments”)^-

9.2 Fee Reduction for Meeting Total Volume Commitment. The total volume commitment is [***] MMBtu (the “Total Volume Commitment”). If Shipper meets its Total Volume Commitment during Contract Years 1-9, which commitment shall include the application of Third Party Gas as provided below, the Gathering Fee then in effect will be reduced [***] per MMBtu effective the first (1^st) day of the Month following the date Shipper meets its Total Volume Commitment, but will remain subject to any other provision herein that operates to change the Gathering Fee thereafter.

9.3 Calculation of Volume Shortfalls. Subject to the provisions of Sections 9.5 and 9.6, if in any Contract Year that Shipper fails to meet the Annual Volume Commitment (a “Volume Shortfall”), Shipper shall elect in writing to either: (i) remit a payment to Gatherer calculated by multiplying the Volume Shortfall for the applicable Contract Year by the Gathering Fee then in effect during the corresponding Contract Year (the “Volume Shortfall Payment”); or (ii) pay an amount of money, divided into twelve (12) equal monthly installments, equal to the Volume Shortfall Payment plus interest at a rate that is the greater of: (X) [***], or (Y) [***] plus the difference between: (i) the 10 Year Note Yield on the last Business Day of the applicable Contract Year; less (ii) the 10 Year Note Yield as of the Effective Date. Gatherer shall calculate the Volume Shortfall and Volume Shortfall Payment, if any, within sixty (60) days after the expiration of Contract Year in which the shortfall occurred, and the results shall be promptly provided in writing to Shipper. Shipper shall remit the Volume Shortfall Payment or first Volume Shortfall Payment monthly installment, if any, within thirty (30) days of receipt of the invoice containing the Volume Shortfall Payment calculation. Subsequent Volume Shortfall and Volume Shortfall Payment calculations and payments shall be made in the same manner upon expiration of each successive Contract Year.

9.4 Third Party Gas to be Applied to Volume Commitments. Any and all Undedicated Shipper Gas and any Gas delivered by a party other than the Preferential Capacity Shippers (collectively, “Third Party Gas”), shall be treated as Shipper Gas for purposes of calculating the Annual Volume Commitments and Total Volume Commitment. Gatherer shall apply Third Party Gas to the Shipper Gas Volume Commitment solely on an MMBtu to MMBtu (i.e., 1:1) basis. Gas delivered by Preferential Capacity Shippers from outside the Committed Area will first be credited to the respective Shipper or Shipper Partner. The balance of Third Party Gas shall be allocated between Shipper and Shipper Partner calculated as a ratio: (i) the numerator of which is Shipper Gas delivered to the Olympia Gathering System, and (ii) the denominator of which is (x) Gas delivered by Shipper Partner from within the Committed Area plus (y) Shipper Gas delivered to the Olympia Gathering System. Any amount by which the volume of actual Gas delivered by Shipper in a Contract Year exceeds the Annual Volume Commitment for the corresponding year (“Excess Delivered Volumes”) shall be deemed part of the volume of actual Gas delivered for the next annual Volume Shortfall calculation. Unapplied Excess Delivered Volumes shall continue to carry forward until used to satisfy a committed quantity or until all commitment years have elapsed. If Shipper has met its Total Volume Commitments under the terms of this Section 9 and/or Section 6 of this Agreement, then such Excess Delivered Volumes shall be applied to Shipper Partner’s Annual Volume Commitments.

9.5 Reduction in Volume Commitment in the Event of Permanent Release. In the event of a permanent release of Gas from the Dedication pursuant to this Agreement, then the Annual Volume Commitments or any Expansion Capacity Annual Volume Commitments shall be proportionately reduced to reflect such release from the Dedication.

9.6 Reduction in Volume Commitment for Failure to Meet Pressure Requirements. Except for reasons of (i) Force Majeure, (n) Plant Maintenance (but not any other maintenance), (iii) the delivery of Shipper Gas in excess of the Gas Specifications, (iv) Shipper delivering Gas in a manner that causes hydraulic constraints, or (v) violation by Shipper of the terms and conditions of this Agreement, in the event that Shipper is unable to produce Gas as a result of a violation of the Pressure Requirements hereunder and/or Gatherer is unable to receive all Shipper Gas tendered to the Olympia Gathering System, then Shipper’s Annual Volume Commitments and/or any Expansion Volume Commitments shall be credited by an amount equal to the product of the following. (i) the Annual Volume Commitment and/or Expansion Capacity Annual Volume Commitment divided by 365 and (ii) the total volume of Shipper Gas tendered to, but not accepted on, the Olympia Gathering System divided by the total capacity of the Olympia Gathering System.

9.7 Reduction in Annual Volume Commitment, Generally. Except as expressly provided for in Sections 9.5 and 9.6 above, the Annual Volume Commitments and/or Expansion Capacity Annual Volume Commitment shall be reduced by any Gas that Gatherer is not able to receive from Shipper on any Day that Shipper is capable of delivering within the Initial Build Conditions, whether or not such failure is caused by Force Majeure.

9.8 Incremental Gas Volumes. Any Incremental Gas delivered pursuant to Section 6 shall count to satisfy the Total Volume Commitment required to achieve the Fee Reduction in Section 9.2.

(a) The Parties are also parties to that separate Gathering and Treating Agreement dated September 1, 2009 (the “Prior Agreement”) in which Shipper has separate volume commitments to deliver Gas through Gatherer’s “Magnolia System.”

(b) If Shipper has available Preferential Capacity on either the Olympia Gathering System or the Magnolia Gathering System Shipper may at its option deliver Gas from one system to the other system up to the available amount of Preferential Capacity on the other system. The gathering fee for such volumes delivered to the other system pursuant to this Section 9.9 (b) will be the then current fee of the system to which the Gas is dedicated. The fuel charge of the Gas delivered shall be the then current fuel charge of the system ultimately receiving the Gas. The Gas delivered will apply (on a 1:1 MMBtu basis) to Shipper’s Annual Volume Commitment and Total Volume Commitment under the agreement to which the Gas is dedicated.

(c) Gatherer’s accommodation herein of Shipper’s delivery of Gas between the systems is expressly contingent that said deliveries do not impede Gatherer’s ability to meet its Pressure Requirements under the Prior Agreement or this Agreement. Should Gatherer’s ability to meet its Pressure Requirements be affected by said deliveries, then Gatherer and Shipper will negotiate in good faith to either add facilities as required to bring the Gas within the applicable Pressure Requirements as Additional Services under the applicable agreement or for Shipper to waive the Pressure Requirements.

(d) Solely if Shipper has met its Volume Commitment under this Agreement and not the Prior Agreement, or vice versa, but in no event if the Volume Commitment is not met in either agreement, then:

(i) If Shipper has Excess Delivered Volumes under this Agreement in any Contract Year, but has a Volume Shortfall under the Prior Agreement (as the term is used in the Prior Agreement), Shipper may elect to apply the Excess Delivered Volume to the Volume Shortfall under the Prior Agreement. The credit to the Volume Shortfall will be calculated by multiplying the Excess Delivered Volume (in MMBtu’s) by a fraction, the numerator of which is the then-current Gathering Rate under this Agreement and the denominator of which is the then-current Gathering Rate under the Prior Agreement.

(ii) If in any Contract Year Shipper has a Volume Shortfall under this Agreement, but has Excess Delivered Volumes (as such term is used in the Prior Agreement) under the Prior Agreement (“CA Excess”), Shipper may elect to apply the CA Excess to the Volume Shortfall under this Agreement. The credit to be applied will be calculated by multiplying the CA Excess (in MMBtu’s) by a fraction, the numerator if which is the then-current Gathering Rate under the Prior Agreement and the denominator of which is the then-current Gathering Rate under this Agreement.

For example: if in the first Contract Year under this Agreement, Shipper has CA Excess of 1000 MMBtu’s, and a Volume Shortfall under this Agreement, Shipper could elect to have a credit applied to the Volume Shortfall under this Agreement of [***] MMBtu’s ([***] equals [***] times [***], or [***] MMBtu’s).

(a) Upon the Effective Date of this Agreement, the Second Amendment shall terminate and be considered as being void ab initio. Any quantities of Gas that flowed prior to the Effective Date will be considered as having flowed under this Agreement.

(b) Gatherer shall continue to maintain the current rented Kinder Morgan Treating Facilities, Sustainable Plant Site Treating Facilities, and the General Posey Site Treating Facilities (or replacement facilities in Gatherer’s discretion with the same Treating capacity as the rented facilities) for a period of three years following the Effective Date of this Agreement. Thereafter, Shipper, Shipper Partner and Gatherer will evaluate in good faith the anticipated future use of the Preferential Treating Capacity and may mutually agree to permanently release the Treating Capacity by providing notice to Gatherer.

10.1 If at any time Gatherer provides terms to any third party delivering Gas into the Olympia Gathering System with respect to a combination of services substantially similar to those provided hereunder that are more favorable than those received (or to be received) by Shipper, then Gatherer shall notify Shipper thereof, and the terms of this Agreement will be deemed amended, retroactive to the date of the execution of the documents between Gatherer and the third party, to provide the same economics and deal terms to Shipper.

11.1 Parent Guaranty. Simultaneously with the execution of this Agreement, Gatherer shall deliver to Shipper a guaranty in the form of Exhibit H attached hereto and made a part hereof for all purposes (the “Guaranty”), executed by Guarantor, pursuant to which Guarantor guarantees to Shipper the timely payment and performance of Gatherer’s obligations under this Agreement.

11.2 Timely Completion of the Olympia Gathering System. The Parties acknowledge and agree that Shipper’s successful development of the Committed Area depends upon the timely completion of the Olympia Gathering System In addition, it may be difficult to calculate the amount of damages or Losses Shipper incurs in the event that the Olympia Gathering System is not completed by the Gathering System Completion Date and in a manner that complies with the Initial Build Conditions. The Parties agree that, in addition to any other rights and remedies available to Shipper hereunder, Shipper is entitled to:

(a) If Gatherer has not completed the Olympia Gathering System by the Gathering System Completion Date and any portion of such failure to complete is due to any reason other than Force Majeure or Shipper’s breach of this Agreement, then Shipper shall be entitled to terminate the Agreement and purchase the existing assets comprising the Olympia Gathering System, as well as the assets acquired pursuant to the PSA, at the (i) actual tax book value of such assets, as determined from the books and records of Gatherer, in the case of newly

constructed facilities, and (ii) the purchase price paid by Gatherer, in the case of the assets acquired pursuant to the PSA; without limiting the foregoing, if the Olympia Gathering System is not completed by the Gathering System Completion Date as extended by reason of Force Majeure or Shipper’s breach of this Agreement the same remedy as provided in this Section 11.2(a) shall apply; or,

(b) If the Olympia Gathering System has not been completed within ninety (90) Days after the Gathering System Completion Date (the “Liquidated Damages Date”), and to the extent that neither party has previously exercised its termination rights under this Agreement, then for each day after the applicable Liquidated Damages Date in which the Olympia Gathering System completion has not occurred, Gatherer shall pay Shipper liquidated damages, and not as a penalty, in the amount of [***] per Day following the Liquidated Damages Date (“Liquidated Damages”). Liquidated Damages which may be owed by Gatherer for any Day shall be proportionately reduced based upon the proportionate volume of Shipper Gas that Gatherer can Gather and Treat on the Olympia Gathering System under this Agreement for that particular Day to the daily capacity of the Initial Build Conditions for the Olympia Gathering System. Liquidated Damages shall not be owed for a period of greater than one year; provided, however, in the event that the Olympia Gathering System has not been completed by the first anniversary of the Liquidated Damages Date, Shipper may exercise the rights provided in Section 11.2(a) above. Notwithstanding the foregoing provisions of this Section 11.2(b), the Liquidated Damages Date shall be extended for any Day, and Gatherer shall have no obligation to pay Liquidated Damages for such Day, in which Gatherer is excused from performance under the terms of this Agreement, including, without limitation, Force Majeure, Plant Maintenance (but not any other maintenance), the failure to designate all Receipt Points as required in Section 5.1, or the delivery by Shipper of volumes in excess of the capacity of the Olympia Gathering System, or if the delay is otherwise caused by Shipper.

All notices, statements, invoices or other communications required or permitted between the Parties shall be in writing and shall be considered as having been given if delivered by mail, e-mail, courier, hand delivery, or facsimile to the other Party at the designated physical address, e-mail address or facsimile numbers. Date of service by mail, courier, or hand delivery is the date on which such notice is received by the addressee, and date of service by e-mail or facsimile is the date sent (as evidenced by the sender’s electronic records if by e-mail or fax machine generated confirmation of transmission if by facsimile); provided, however, if such date received is not a Business Day, then date of receipt will be on the next date that is a Business Day, and if an e-mail or facsimile is received after 5:00 pm local time, then date of receipt will be the next Business Day Normal operating instructions can be delivered by telephone or other agreed means Notice of events of Force Majeure may initially be made by telephone and shall be confirmed in writing as soon as reasonably practicable after the telephonic notice. Monthly statements, invoices, payments and other communications shall be deemed delivered when actually received or when receipt is refused. Either Party may change its physical address, email address or facsimile or telephone numbers upon written notice to the other Party, but such change shall not be effective until thirty (30) days after receipt by the other Party.

This Agreement may be executed in any number of counterparts, each of which shall be considered an original, and all of which shall be considered one instrument.

Shipper and Gatherer each represent and warrant to each other that on and as of the effective date hereof.

(a) it is duly formed and validly existing and in good standing under the laws of its state of Jurisdiction or formation, with power and authority to carry on the business in which it is engaged and to perform its respective obligations under this Agreement;

(b) the execution and delivery of this Agreement by it have been duly authorized and approved by all requisite corporate, limited liability company, partnership or similar action; (c) it has all the requisite corporate, limited liability company, partnership or similar power and authority to enter into this Agreement and perform its obligations hereunder,(d) the execution and delivery of this Agreement does not, and consummation of the transactions contemplated herein will not violate any of the provisions of its organizational documents, any agreements pursuant to which it or its property is bound or, to its knowledge, any applicable Laws, and

(c) this Agreement is valid, binding and enforceable against it in accordance with its terms subject to bankruptcy, moratorium, insolvency and other Laws generally affecting creditors’ rights and general principles of equity (whether applied in a proceeding in a court of law or equity).

The Committee of Management will negotiate and attempt to reach a resolution of the Dispute. If Gatherer has also either issued or received a Dispute Notice from Shipper Partner with respect to a related dispute, Shipper shall have the right to participate in the Committee of Management discussions with respect to the related dispute.

16.2 Waiver of Jury Trial. EACH PARTY HERETO HEREBY KNOWINGLY, VOLUNTARILY, IRREVOCABLY AND INTENTIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY PROCEEDING BASED HEREON, OR ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT. THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE PARTIES TO ENTER INTO THIS AGREEMENT.

16.3 Jurisdiction and Venue. Each Party hereby irrevocably consents and agrees that any legal action or proceedings hereunder or for temporary injunctive relief shall be brought in any of the courts of the State of Texas or the courts of the United States of America, in either case located in Houston, Texas having subject matter jurisdiction, and, by execution and delivery of this Agreement and such other documents executed in connection herewith, each Party hereby (i) accepts the jurisdiction of the aforesaid courts, (ii) irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceedings with respect to such documents brought in any such court.

17.1 Title and Custody. Title to carbon dioxide from Shipper’s Gas shall remain with Shipper and shall not transfer to Gatherer, unless otherwise mutually agreed by the Parties. Shipper may elect to receive and, in which case, shall be solely responsible to arrange for recovery of, physical custody and transportation of the carbon dioxide collected by the Olympia Gathering System. Notwithstanding the foregoing, unless Shipper elects to receive and take custody of the carbon dioxide as set forth in the preceding sentence, Gatherer will have custody of the carbon dioxide and will comply with all applicable reporting requirements by governmental authorities.

17.2 CO2 Taxes. Subject to the provisions of Section 17.3, Shipper shall have sole responsibility for its pro rata share of any tax, fee, cost, assessment or similar penalty arising from or related to carbon dioxide or other greenhouse gas emissions (including but not limited to nitrous oxide, hydroflourocarbons, perflourocarbons and sulfur hexafluoride) from the treatment and processing of Shipper’s Gas necessary to comply with the specifications of Interconnecting Pipelines (“CO2 Tax”) which may be enacted or imposed in any legislation or regulation after the Effective Date. Shipper hereby agrees to indemnify, defend and hold harmless Gatherer from and against any and all Losses arising out of or related to any CO2 Tax except as provided herein. Provided however that in no event shall Shipper be responsible for any CO2 Tax that (i) is attributable to non-Shipper Gas; (ii) is passed through by Gatherer by any other means to other third party shippers, (iii) is attributable to Gatherer removing CO2 that is beyond the amounts necessary to allow Shipper’s Gas to comply with the applicable specifications of the Interconnecting Pipelines nominated by Shipper; or (iv) is attributable to any tax, fee, cost, assessment or similar penalty (excluding the CO2 Tax) arising from or related to carbon dioxide or other greenhouse gas emissions generated by the Olympia Gathering System in providing the Gathering services contemplated herein.

17.3 Notice. Gatherer will provide Shipper with prompt notice of any legislation or regulation requirement related to the CO2 Tax and as soon as practicable thereafter, consult with Shipper concerning a commercially and operationally feasible proposed project scope to meet such requirement and the anticipated, reasonable costs and expenses of executing such scope The Gatherer and Shipper will negotiate in good faith to select and implement the most cost-effective solution available to satisfy the governmental authorities’ requirements, including the Gatherer and Shipper offsetting such costs by using CO2 Credits as defined below.

(a) Gatherer shall convey to Shipper at no cost to Gatherer, any present or future right, title, credit, offset, unit, claim, allowance, acknowledgement, allocated pollution right, benefit, value, or interest in or related, in whole or in part, to the processing, transporting and Treatment of Shipper’s Gas or other rights that may reduce the cost to Shipper of any CO2 Tax (“CO2 Credits”) generated, earned or otherwise acquired by the Olympia Gathering System facilities.

(b) Shipper may, at its sole option, in lieu of paying any such CO2 Tax, satisfy or avoid such CO2 Tax by the use of CO2 Credits which Shipper controls If Gatherer has any CO2 Credits or offsets and uses them for customers or contract obligations of a substantially similar nature to the operations it is performing for Shipper, it will use such CO2 Credits or offsets on a pro rata basis among all such similar operations in meeting its obligations under this Agreement.

To the extent there is more than one Preferential Capacity Shipper at the time the remedies provided for in 5.3(b), 7.3 and 11.2 are exercised by Shipper, then such rights and obligations shall apply to the Shipper pursuant to Shipper’s pro-rata share of the Preferential Capacity as determined pursuant to the provisions of Section 5.9. Provided however that with respect to Section 7.3, Shipper’s rights provided herein shall only be limited in the event that a Preferential Capacity Shipper participates in the request for Additional Services as provided for in Section 7.2.

IN WITNESS WHEREOF, the Parties have executed this Agreement on the date first set forth above

On or before the 20^th day of each calendar month, Gatherer shall provide written notice to Shipper of Gatherer’s good faith estimate of any capacity allocations or curtailments anticipated, based on then currently available information, to be required or necessary during the next succeeding calendar month. In the event that the 20^th day of the calendar month is a weekend or holiday, such notice will be provided on the last Business Day preceding the 20^th day of such calendar month.

6.2 Nomination Procedures. Pursuant to the terms of this Agreement, the nomination procedures detailed in this Section will be utilized by Shipper with respect to Gathering of Gas hereunder. All nominations must be made by Shipper or Shipper’s designee Should Interconnecting Pipelines receiving Gas revise their nomination requirements in a manner that conflicts with the nomination procedures herein, the Parties agree to negotiate changes to the nomination procedures herein as are reasonably required.

(a) Shipper’s nomination(s) shall be accepted and scheduled for delivery by Gatherer to the extent that (i) Gas is sufficient to support the nominations, (ii) Shipper has sufficient capacity in the Gathering System, as the case may be, allocated to Shipper pursuant to the terms and conditions of this Agreement, and (iii) the party receiving Gas at the Redelivery Points accepts Shipper’s nominations. Upon being scheduled for delivery, Gatherer’s dispatcher shall thereupon advise Shipper in writing, via fax, e-mail or web-based nomination process, of the quantity scheduled for Gathering (a “Scheduled Nomination”) and the reason for any failure to schedule any Gas nominated by Shipper.

(b) The designated operator of each Receipt Point will provide Gatherer with the percentage of Gas attributable to each Shipper at each Receipt Point on the Gathering System. Gatherer will apply such percentages to determine Shipper’s volume in MMBtus of Gas received by Gatherer at the Receipt Point(s). Such percentages may be updated upon notice from the designated operator to Gatherer at any time

(c) Each nomination shall be made in conformance with the North American Energy Standards Board timeline as follows, which may change from time to time (all timelines are stated in Central Time):

(d) Shipper shall provide to Gatherer’s dispatcher in writing, via fax, e-mail, or web-based nomination process the actual daily nominations of the quantities to be delivered by Gatherer for Shipper’s account at each Redelivery Point in accordance with Gatherer’s requirements. Such nominations shall include the information requested by Gatherer, and Gatherer shall maintain a record of such nominations. By July 1, 2010, Gatherer shall incorporate a web-based electronic bulletin board nomination system which will allow Shipper nominations during each nomination cycle identified in Section 6.2 (c). From the Effective Date until such time that the web-based electronic bulletin board nomination system is fully operational, Gatherer will provide Shipper the opportunity to make nomination changes each cycle via e-mail or facsimile correspondence

(e) Gatherer may, but is not obligated to, accept (i) any nomination which exceeds Shipper’s allocated capacity on the Gathering System, as the case may be, or (ii) any revisions to a prior nomination which result in an increase in quantities of Gas Shipper desires to deliver to a Redelivery Point which are not supported by increased deliveries of Gas to the Gathering System, as the case may be.

(a) Imbalances. If the number of MMBtus of Gas received by Gatherer at the Receipt Points, after subtracting Fuel, do not equal Shipper’s Scheduled Nomination(s), an imbalance exists. If the number of MMBtus of Gas received by Gatherer at the Receipt Point(s), after subtracting Fuel are less than Shipper’s Scheduled Nomination(s), a negative imbalance exists If the number of MMBtus of Gas received by Gatherer at the Receipt Point(s), after subtracting Fuel, are greater than Shipper’s Scheduled Nomination(s), a positive imbalance exists. The term balance or balancing refers to equalizing the number of MMBtus of Gas received by Gatherer at the Receipt Point(s) with the number of MMBtus constituting Shipper’s Scheduled Nomination(s) plus Fuel. The Parties shall use reasonable efforts to minimize these imbalances and agree to make the daily and monthly adjustments as outlined herein At Gatherer’s sole discretion, Gatherer may decline such nomination if necessary to balance Shipper.

(b) Daily Balancing. Each Day Shipper shall cause the number of MMBtus of Gas being delivered at the Receipt Point(s) to equal as closely as practicable Shipper’s Scheduled Nomination(s) plus Fuel. Whenever the number of MMBtus of Gas being delivered at the Receipt Point(s) is insufficient to support Shipper’s Scheduled Nomination(s) plus Fuel, Shipper shall promptly decrease its daily Scheduled Nomination Whenever the number of MMBtus of Gas being delivered at the Receipt Point(s) exceeds Shipper’s Scheduled Nomination(s) plus Fuel, Shipper shall promptly increase Scheduled Nominations. If Shipper does not adjust such nomination, Gatherer may, in its sole discretion, decline such nomination if necessary to balance Shipper. Notwithstanding the foregoing, Shipper may request the right to create a daily imbalance when necessary to counteract a prior daily imbalance. Whether such request will be granted is within the sole discretion of Gatherer Notwithstanding anything to the contrary herein, Shipper will not be required to reduce the Scheduled Nomination below the number of MMBtus of Gas received by Gatherer less Fuel or increase the Scheduled Nomination above the number of MMBTU’s received by Gatherer less Fuel.

(c) Monthly Balancing. At the end of each month, the cumulative imbalance shall be designated as “Cash Out Quantities” and reduced to zero volume by cash out. The cash out price will be the 100% cash out index price calculated pursuant to the respective Interconnecting Pipeline’s Pipeline Tariff on which the imbalance occurred, exclusive of any imbalance penalties For avoidance of doubt, any and all penalties and other charges including charges resulting from Gatherer being cashed out at a price above or below the 100% cash out index price pursuant to the Pipeline Tariff from the Interconnecting Pipelines shall be incurred by Gatherer, and Shipper shall be held harmless from paying any such penalties or charges.

(d) Third Party Cooperation. Both Parties recognize that Gatherer’s ability to balance Shipper is dependent upon the cooperation of the Parties and third parties.

(e) Interconnecting Pipelines. Whenever an Interconnecting Pipeline requires Gatherer to balance, Gatherer may require Shipper to make adjustments to nominations as imposed by the Interconnecting Pipeline.

(f) Duty to Maintain Balance. Gatherer shall use reasonable efforts to require all shippers using the Gathering System to maintain balance thereon in accordance with Section 1.3 of these General Terms and Conditions.

6.4 Curtailment Losses. Gatherer shall not be liable for Losses caused by any curtailment imposed by Gatherer unless such curtailment is clue to negligence of Gatherer.

7.1 Receipt Point Gas Specifications. Shipper Gas delivered by Shipper to the Receipt Points shall meet the following specifications (collectively, the “Gas Specifications”):

The blend of Shipper Gas received from all Receipt Points on the Olympia Gathering System shall meet the following additional quality specifications:

7.2 Non-conforming Gas. If at any time Gatherer becomes aware that Shipper Gas at the Receipt Points fails to conform to the Gas Specifications, then (1) Gatherer shall give Shipper written notice of the deficiency and Shipper shall immediately remedy the deficiency and (ii) Gatherer may, in addition to any other rights and remedies that Gatherer has hereunder or at law or in equity, take any combination of the following actions:

(b) immediately cease receiving the non-conforming Shipper Gas from Shipper by shutting in the sources of such non-conforming Shipper Gas or by other appropriate means and shall notify Shipper that Gatherer has ceased, or will cease, receiving the non-conforming Shipper Gas. Gatherer shall operate the system to curtail Shipper Gas in such a fashion as to maximize total production volumes of Shipper Gas on the Olympia Gathering System.

Acceptance by Gatherer of Shipper Gas that does not conform to the Gas Specifications shall not constitute a waiver of the Gas Specifications by Gatherer in regard to Shipper Gas delivered under this Agreement in the figure, nor shall acceptance without an express written waiver constitute a waiver of any claim for damage resulting from delivery of Shipper Gas not meeting the Gas Specifications.

If Gatherer is unable to take non-conforming Gas for a period of thirty (30) cumulative days in a year, and Gatherer does not intend to modify or expand the Gathering Facilities, or provide Additional Services under Section 7 of this Agreement, in order to enable Gatherer to receive such non-conforming Gas, then, without limiting any other applicable provisions of the Agreement, such non-conforming Gas shall be permanently released from the Dedication at the election of Shipper.

8.1 Measurement. The quantity and “Grass Heating Value” of Gas received and delivered hereunder shall be determined based on the gross number of Btus that would be contained in the volume of such Gas with actual water vapor and at the Contract Pressure and Contract Temperature determined by methods in general use by Gatherer, or its designee, from time-to-time and in accordance with good engineering practices, provided, however, if the Gas as delivered contains seven (7) pounds of water or more per one million cubic feet, such Gas shall be assumed to be saturated with water vapor.

8.2 Installation and Operation of Measuring Facilities. Gatherer or its designee shall have the right to install, own, operate, modify and maintain measuring facilities (which shall include facilities used for sampling) used for purposes of measuring the Gas received and delivered by Gatherer at any Receipt Point or Redelivery Point. Where used, orifice meters shall

employ dual chamber orifice meter runs built to meet API 14.3 and shall be installed and operated in accordance with the referenced AGA Measurement Committee Report No. 3 ANSI/API 2530, as amended from time-to-time or such other standards in general use by Gatherer. If turbine meters are used, they shall be installed and operated in accordance with the AGA Transmission Measurement Committee Report No. 7, as amended from time-to-time or such other standards in general use by Gatherer. If other types of measurement devices or instruments are used, the installation and operation of such facilities shall be in accordance with terms and procedures acceptable to Gatherer. When Gatherer determines that pulsation problems or other measurement inaccuracies result from the activities of Shipper or other third parties, in addition to any remedies otherwise available to it, Gatherer shall have the right to require Shipper to install pulsation bottles or take such other corrective action as Gatherer deems necessary or require Shipper to cause the third parties to take such action, or Gatherer may make appropriate adjustments.

8.3 Meter Testing. The measuring equipment (which shall for avoidance of doubt include any equipment used for sampling) shall be calibrated by the Gatherer at reasonable intervals, and, if requested, in the presence of representatives of the Shipper. All meters averaging over 5 MMcf per Day will be tested monthly, those averaging less than 5 MMcf per Day but more that 1 MMcf per Day will be test quarterly, meters averaging less than 1 MMcf per Day will be tested semi-annually Readings, calibrations, tests, repairs and adjustments of the Gatherer’s metering and testing equipment, and changing of charts, shall be done only by the Gatherer or its representative and in accordance with good engineering practice as often as found necessary in operation. Gatherer shall not be required to calibrate any equipment more frequently than once per year if the average monthly volume of the equipment for any three (3) month period is less than 0.1 MMcf per Day. Subject to the limitations of 8.2 of these General Terms and Conditions, upon Shipper’s request, the Gatherer shall test and calibrate at a mutually agreeable time, if necessary, any particular meter or other equipment, the cost of such special test, or any other test or adjustment requested by the Shipper and agreed to by the Gatherer, to be borne by the Shipper, unless the percentage of inaccuracy exceeds one percent (1%). If upon any test the total inaccuracy from meter or auxiliary equipment error exceeds one percent (1%), previous readings shall be corrected, but not beyond one-half the period of time since the last test or three (3) Months, whichever is less. If the total inaccuracy is not more than one percent (1%), previous readings shall be considered correct, but immediately following the test the equipment shall be adjusted, if necessary, to read accurately. Any measurement error resulting from the inaccuracy of a meter or auxiliary equipment shall be corrected for Shipper’s account through prospective allocations only, If any meter or auxiliary equipment is out of service or repair or registering inaccurately for a period of time so that the amount of Gas cannot be computed from the reading thereof, the Gas delivered during such period shall he estimated on the basis of the first of the following methods feasible in Gatherer’s reasonable judgment. (a) correct the error if the percentage of error is ascertainable by calibration, test or mathematical calculation; or (b) estimate the volume on the basis of deliveries during preceding or subsequent periods under similar conditions when the equipment was registering accurately.

8.4 Receipt Point and Delivery Point Sampling. Gatherer shall sample the flowing Gas stream at the Receipt Point utilizing one of the following methods.

If an accumulated sample is utilized the application of Gas quality in the volume calculation will be the time period that the Gas sample was accumulated. Such Accumulated Sample shall be analyzed once a month Accumulated samples or on-line chromatograph for Receipt Point volumes less than the above stated volume can be utilized if the Parties mutually agree.

(b) Spot Sample – Receipt Points with an average production during the previous six (6) months or a current monthly average volume less than or equal to 50,000 Mcf per day shall utilize a Spot Sample. If this method is utilized the application of Gas quality in the volume calculation will be the time period beginning on the date the sample was obtained until the next sample is obtained

(i) A Spot Sample shall be analyzed once a month if Receipt Point average production during the previous six (6) Months or a current monthly average volume is greater than or equal to 5,000 Mcf per day.

(ii) A Spot Sample shall be analyzed once a quarter if Receipt Point average production during the previous six (6) Months or a current monthly average volume is less than 5,000 Mcf per day

(iii) Delivery Point samples timing and methodology shall be in accordance with the requirements of the Downstream Transporter, but shall utilize either an Accumulated Sample or On-line Chromatography and a monthly sampling process.

(a) Subject to Section 9.5 below of the General Terms and Conditions, if any undisputed amount due hereunder remains unpaid for ninety (90) days after the due date, Gatherer shall have the right to suspend or discontinue services hereunder until any such past due amount is paid. Following any such ninety (90) day period, if Shipper remains in default, Gatherer may, in addition to requiring payment of all sums then due, require Shipper to, at Shipper’s option. (i) prepay an amount equal to Gatherer’s reasonable estimate of the fees

Shipper would incur for two (2) Months of service hereunder; (ii) furnish an irrevocable letter of credit in a form acceptable to Gatherer in the amount of the required prepayment; or (iii) provide any other mutually acceptable form of security ((i), (ii) or (iii) being, as applicable, the “Default Security”). If Shipper makes timely payment of all undisputed amounts due under this Agreement for a period of one (1) year following the date that any Default Security is tendered, the Default Security shall be returned to Shipper. At such time as Shipper pays all undisputed amounts and, if applicable, provides Default Security, Gatherer shall immediately resume providing services hereunder.

(b) Upon request of either Party, the other Party, or in the case of Gatherer, Gatherer shall deliver for itself and Guarantor, within thirty (30) days of such request: (i) audited consolidated financial statements for the most recent fiscal year; (ii) if the Party providing the information does not have audited financial statements, then certified consolidated unaudited financial statements for the most recent fiscal year; or (iii) a copy of the relevant quarterly report containing unaudited consolidated financial statements for the latest fiscal quarter (“Financial Information”) In all cases the statements shall be prepared in accordance with generally accepted accounting principles, provided, however, that should any such statements not be available on a timely basis due to a delay in preparation or certification, such delay shall not be an event of default so long as the Party diligently pursues the preparation, certification and delivery of the statements.

(c) If Gatherer reviews the Financial Information and has reasonable grounds for insecurity concerning Shipper’s ability to pay the amounts due for services under this Agreement in a timely manner, Gatherer will send written notice to Shipper of Gatherer’s desire to meet with Shipper. Gatherer and Shipper will negotiate in good faith to determine if Shipper should be required to provide Default Security, notwithstanding that Shipper may not be, at such time, in default as set forth in Section 9.4(a), above. If Gatherer thereafter determines that it has a reasonable basis to question Shipper’s ability to pay for amounts due for services under this Agreement, Shipper will post Default Security if Shipper makes timely payment of all undisputed amounts due under this Agreement for a period of one (I) year following the date that any Default Security is tendered, the Default Security shall be returned to Shipper.

9.5 Payment Disputes. In the event of any dispute with respect to any payment hereunder, Shipper shall make timely payment of all undisputed amounts

9.6 Interest on Late Payments. In the event that Shipper or Gatherer shall fail to make timely payment of any sums, except those contested in good faith or those in a good faith dispute, when due under this Agreement, interest will accrue at an annual rate equal to the prime rate as published in the “Money Rates” section of The Wall Street Journal plus one percent (1%) from the date payment is due until the date payment is made.

10.1 Definition of Force Majeure. The term “Force Majeure” as used in this Agreement shall mean any cause or causes not reasonably within the control of the Party claiming suspension and which, by the exercise of reasonable diligence, such Party is unable to prevent or overcome To the extent not reasonably within the control of the Party claiming

suspension and which, by the exercise of reasonable diligence, such Party is unable to prevent or overcome, examples of Force Majeure may include, but are not be limited to Acts of God; acts, omissions to act and/or delays in action of federal, state or local government or any agency thereof; strikes, lockouts, work stoppages or other industrial disturbances; acts of the public enemy; acts of terrorism; wars; blockades; insurrections; sabotage; riots, epidemics, landslides, lightning; earthquakes; fires; storms; floods; washouts; arrests or restraint of governments, rulers or peoples, civil or criminal disturbances, interruptions by governmental or court orders; present and future valid orders of any regulatory body having jurisdiction; explosions, mechanical failures; breakage or accident to equipment, machinery or lines of pipe, compressors or plants (not due to the negligence or willful misconduct of the Party) and subsequent repairs; freezing or blockage of lines of pipe, partial or entire failure of production facilities or equipment, treating plants, processing plants, or transportation facilities or separation facilities; partial or entire failure or refusal of operators of downstream pipelines or facilities to receive Shipper Gas or increases in pressure of downstream pipelines or facilities; governmental regulations; curtailment of, or other inability to obtain, equipment, labor, materials or supplies and/or services and/or electric power used in making and/or receiving deliveries hereunder; the inability of either Party to acquire, or the delays on the part of a Party in acquiring, at reasonable cost and after the exercise of reasonable diligence, approvals, permits, consents, easements and/or rights-of-way, and compliance with applicable environmental statutes.

10.2 Effect of Force Majeure. In the event either Party is rendered, wholly or in part, by Force Majeure, unable to carry out its obligations under this Agreement, other than to make payments of any amount due hereunder, it is agreed upon such Party giving notice and full particulars of such Force Majeure, in writing, including the estimated duration of the Force Majeure event, to the other Party as soon as possible after the occurrence of the causes relied on, then the obligation of the Party giving such notice, so far as they are affected by such Force Majeure, shall be suspended during the continuance of any inability so caused, but for no longer period, and such cause shall, so far as reasonably possible, be remedied with all reasonable dispatch; provided, however, that this provision shall not require the settlement of strikes or lockouts by acceding to the demands of the opposing parties when such course is inadvisable at the discretion of the Party having the difficulty. If Shipper experiences an event of Force Majeure, Shipper shall change its nomination as quickly as possible in order to minimize imbalances on the Olympia Gathering System, as the case may be, and the impact of Shipper’s Force Majeure condition on downstream allocations.

Note 1 If requested prior to 12/31/2010, Shipper may elect a quantity of the 4” meter runs be replaced with larger meter runs according to a substitution factor For example, Shipper may elect (39) 8” senior meter runs in lieu of (78) 4” meter runs As substitutions are made and agreed upon, this table will be updated and attached to the agreements

Upon an Expansion Request by a Shipper pursuant to Section 6, the Gathering Fee will be recalculated pursuant to the Revised Gathering Fee Calculation in this Exhibit F and shall be effective upon the in-service date for the relevant Expansion Capacity. For any Expansion, the applicable Base Fee identified in the tables below will be the Base Fee that corresponds to the amount of applicable Olympia System Capacity (as the case may be) resulting from the Expansion (the “Applicable Base Fee”). Unless otherwise agreed, Expansions shall be made in multiples of 100 MMcf/d (gross), with the exception of the second expansion which will be at 120 MMcf/d (gross), up to 520 MMcf/d (gross) at any given time within the first five (5) years after the Effective Date.

Notwithstanding the calculations for Revised Gathering Fees in this Exhibit F, the Revised Gathering Fees shall continue to be subject to escalation and de-escalation factors as per Section 4, 7, and 9.2 of the Agreement.

Incremental Capacity for 1^st election (if any) * Applicable Base Fee * Inflator # 1

Incremental Capacity for 2^nd election (if any) * Applicable Base Fee * Inflator # 2

Incremental Capacity for 3^rd election (if any) * Applicable Base Fee * Inflator # 3

Incremental Capacity for 4^th election (if any) * Applicable Base Fee * Inflator # 4

Incremental Capacity for 5^th election (if any) * Applicable Base Fee * Inflator # 5

(ii) Divided by the total System Capacity For avoidance of doubt, the total System Capacity shall include the current Expansion and any previous Expansions from the applicable System.

Where the Inflator attributable to each Expansion shall be determined by the formula below:

Where the “Cost Index” is the Producer Price Index Industry Data (Series Id: PCU2111112111113) for the Crude Petroleum & Natural Gas Extraction Industry, under the Natural gas (from the well head) product category, Base Date 198406 published by the U.S. Bureau of Labor and Statistics.

Where the Initial Cost Index is Cost Index averaged for the 2-month period prior to April 2010.

Where the Future Cost index is the average of the Cost Index for the 12-month period immediately prior to election of incremental capacity. Each Expansion will have a unique Future Cost Index that will not change once established.

In the event of more than one Expansion, the new Applicable Base Fee will apply to the calculation of the current Expansion and each preceding Expansion. The new Inflator however shall only be applied to the calculations applicable to the Year the current Expansion is taking place The previous Inflators used during earlier Expansion(s) shall be multiplied by the new Applicable Base Fee for the portions of the calculation applicable to the year such inflator was established

Example, illustrating Revised Gathering Fee Calculation for Expansions made on the Olympia Gathering system:

Year 1 – 220 MMcf/d, assumed Future Cost Index is 10% higher than the Initial Cost Index for purposes of example (e.g. ((Future Cost Index – Initial Cost Index)/(Initial Cost Index)) =10%

Year 2 – 100 MMcf/d, assumed Future Cost Index is 10% higher than the Initial Cost Index for purposes of example –10%

Year 3 – 200 MMcf/d, assumed Future Cost Index is 15% higher than the Initial Cost Index for purposes of example –15%

The Revised Gathering Fee for Year 1, where the Olympia Gathering System is expanded by 220 MMcf/d increasing the Olympia Gathering System Capacity to 800 MMcf/d is calculated as follows:

Revised Gathering Fee = [***]/MMBtu; the Revised Gathering Fee applies to Gas flowing on the Olympia Gathering System

The Revised Gathering Fee for Year 2, where the Olympia Gathering System is expanded by an incremental 100 MMcf/d increasing the System Olympia Gathering System Capacity to 900 MMcf/d is calculated as follows:

Revised Gathering Fee =[***]/MMBtu; the Revised Gathering Fee applies to Gas flowing on the Olympia Gathering System.

The Revised Gathering Fee for Year 3 where, the Olympia Gathering System is expanded by an incremental 200 MMcf/d increasing the Olympia Gathering System Capacity to 1,100 MMcf/d is calculated as follows:

Revised Gathering Fee = [***]/MMBtu; the Revised Gathering Fee applies to Gas flowing on the Olympia Gathering System.

THIS GUARANTY is made this 29^th day of April 2010 (the “Effective Date”) by CenterPoint Energy, Inc. (“Guarantor”), to and for the benefit of SWEPI LP, and its successors and assigns (“SWEPI”) under certain gas gathering and treating agreements between SWEPI, as “Shipper,” and CenterPoint Energy Field Services, Inc., a subsidiary of Guarantor, as “Gatherer” (“CEFS”), relating to the provision of gathering and treating services for natural gas produced by SWEPI in Red River, DeSoto, Sabine, and Natchitoches Parishes, Louisiana.

limitation, those relating to indemnity, due and payable to SWEPI under the GGAs (collectively, the “Obligations”). The Obligations expressly exclude and Guarantor shall not be liable for: (1) indirect, special or consequential damages, or (2) punitive or exemplary damages. Guarantor agrees that this Guaranty is a guarantee of the Obligations and that Guarantor is primarily liable and responsible for the Obligations. It is not necessary for SWEPI, in order to enforce the Obligations by Guarantor under this Guaranty, first or contemporaneously to institute suit or exhaust remedies against CEFS or others liable for any of the Obligations. In addition to Guarantor’s liability for the Obligations herein, Guarantor agrees to pay any losses, damages, or expenses, including reasonable attorney’s fees, incurred by SWEPI in enforcing any rights under the either GGA or this Guaranty. All defined terms in the GGAs shall have the same meaning in this Guaranty.

THIS GUARANTY REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES TO IT AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.
