In addition, Gatherer shall utilize commercially reasonable efforts to complete construction of the specific construction milestones for the Magnolia Gathering System detailed in the attached Exhibit D (the “Milestone Completion Dates”), which may be revised upon mutual agreement of the Preferential Capacity Shippers and Gatherer. If Gatherer anticipates, in its reasonable judgment and opinion, that it will not meet a Milestone Completion Date, then Gatherer shall provide Shipper as much advance notice as reasonably possible.

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 Magnolia 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 xxxxx 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 xxxxx, 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 xxxxx; 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 Magnolia Gathering System for which Gatherer has not met an applicable Milestone Completion Date at Shipper’s sole cost and expense and elect to either: (i) 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 Magnolia 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 Magnolia 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 Magnolia 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 each of 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 119.33 miles of six-inch diameter pipeline as detailed in Exhibits B and C. Anytime on or before March 1, 2010, the Preferential Capacity Shippers may elect to utilize up to 119.33 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 119.33 miles. The 119.33 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 119.33 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 two existing Interconnections with Gulf South Pipeline Company’s Legacy System, one on each WOR and EOR. Gatherer will: (i) redeliver Shipper Gas produced from EOR xxxxx or WOR xxxxx to those existing Interconnections with Gulf South Pipeline Company’s Legacy System; and (ii) construct in total for Preferential Capacity Shippers three (3) additional EOR Interconnections and two (2) additional WOR Interconnections (for a total of five new Interconnections) as described on Exhibit L One of the three new Interconnections EOR will be to Gulf South Pipeline Company’s Legacy System downstream of Gulf South’s Hall Summit compressor station at a location near the area known as the “Magnolia Site” located in Section 0, Xxxxxxxx 00, Xxxxx 0, Xxx Xxxxx Xxxxxx, Xxxxxxxxx. The location of the remaining points of Interconnection shall be subject to Gatherer’s sole discretion, reasonably exercised. These five 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 five Interconnections referenced above are designed to accommodate a capacity of two hundred fifty (250) 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 Magnolia 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 (1) 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 as provided herein, including, without limitation, blending capacity. of the Magnolia 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 Magnolia 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 Magnolia 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.

(a) With respect to any multi-line rights of way that are obtained by Gatherer from Shipper pursuant to the PSA, Gatherer will assign to Shipper the right to construct and operate the pipelines identified on Exhibit K. Such pipeline(s) shall be constructed and operated (a) at the sole risk and expense of Shipper, (b) pursuant to spacing specifications and requirements of Gatherer and in a manner that does not interfere with Gatherer’s operations, (c) at a location and within a specific area, approved in writing by Gatherer. Gatherer shall assign to Shipper the right to construct and operate pipelines in addition to those referenced in Exhibit K provided that such pipelines comply with requirements (a)-(c) in the foregoing sentence of this Section and do not adversely affect Gatherer’s future plans and anticipated needs in order to provide service under this Agreement.

(b) 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.

SECTION 6. EXPANSION CAPACITY

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 Magnolia Gathering System (“Expansion Capacity”), Gatherer shall expand the Magnolia 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 Magnolia Gathering System (which, for the avoidance of doubt, is inclusive of the Initial Build Laterals) in minimum of 100 MMcf per Day increments up to a maximum additional capacity of 500 MMcf per Day to the FOR system and 500 MMcf per Day to the WOR system. Each 100 MMcf per Day increment may not be divided between FOR and WOR. The Expansion Capacity Request will specify Shipper’s requested additional capacity increase amount (in 100 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 100 MMcf per Day increment at any one time. The Gathering Fee for all Gas delivered and Gathered through the Magnolia 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 100 MMcf 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 make 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 1,000 MMcf per Day for FOR and a total of 700 MMcf per Day for WOR 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 MMBtu’s 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) MMBtu’s per Mcf. 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 Magnolia Gathering System by Shipper, Shipper Partner and/or Third Party Gas.

SECTION 7. ADDITIONAL SERVICES AND INTERCONNECTIONS

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).

SECTION 8. GATHERER PRESSURE REQUIREMENTS

8.1 Pressure Requirements. Gatherer shall maintain the following daily pressure requirements on the Magnolia 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 (i) 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 (i) 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.

SECTION 9. ANNUAL VOLUME COMMITMENTS

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”):


Contract Year 1: [***] MMBtu		Contract Year 6: [***] MMBtu
Contract Year 2: [***] MMBtu		Contract Year 7: [***] MMBtu
Contract Year 3: [***] MMBtu		Contract Year 8: [***] MMBtu
Contract Year 4: [***] MMBtu		Contract Year 9: [***] MMBtu
Contract Year 5: [***] MMBtu		Contract Year 10: [***] MMBtu

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 (1st) 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. The Contract Year 1 Volume Commitment shall commence on the Effective Date and shall run through the first anniversary of the Effective Date. 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 a 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 Magnolia 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 Magnolia 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, (ii) 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 Magnolia 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 Magnolia Gathering System divided by the total capacity of the Magnolia 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.

SECTION 10. FAVORED NATIONS

If at any time Gatherer provides terms to any third party delivering Gas into the Magnolia 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.

SECTION 11. PARENT GUARANTY AND LIQUIDATED DAMAGES

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 Magnolia Gathering System. The Parties acknowledge and agree that Shipper’s successful development of the Committed Area depends upon the timely completion of the Magnolia Gathering System. In addition, it may be difficult to calculate the amount of damages or Losses Shipper incurs in the event that the Magnolia 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 Magnolia 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 Magnolia 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 Magnolia 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 Magnolia 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 Magnolia 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 Magnolia Gathering System under this Agreement for that particular Day to the daily capacity of the Initial Build Conditions for the Magnolia Gathering System. Liquidated Damages shall not be owed for a period of greater than one year; provided, however, in the event that the Magnolia 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 Magnolia Gathering System. or if the delay is otherwise caused by Shipper.

SECTION 12. NOTICES

All notices, statements, invoices or other communications required or permitted between the Parties shall be in writing and shall he 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, e-mail 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.

(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 Mountain Time):


	Nomination Due:	For Flow at:
Cycle 1 (Timely)	10:30 AM	8:00 AM Next Day
Cycle 2 (Evening)	5:00 PM	8:00 AM Next Day
Cycle 3 (Intra-day 1)	9:00 AM	4:00 PM Same Day
Cycle 4 (Intra-day 2)	4:00 PM	8:00 PM Same Day

(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.

APPENDIX A-11

6.3 Shipper Gas Balancing.

(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 MMBtu’s of Gas received by Gatherer less Fuel or increase the Scheduled Nomination above the number of MMBtu 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.

APPENDIX A-12

(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 this 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 due to negligence of Gatherer.

SECTION 7. GAS QUALITY

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

(a) commercially free from dust, gum, gum-forming constituents and solid or liquid matter which might interfere with its merchantability or cause injury to or interfere with proper operation of the Magnolia Gathering System or the Interconnecting Pipelines;

(b) free of hydrocarbons and water in their liquid state;

(c) commercially free from crude oil, mineral seal, distillate and other impurities that would adversely affect Gatherer’s deliveries to receiving processing plants or other third party transporters;

(l) Nitrogen – not to exceed three percent (3%) by volume;

(m) Oxygen – 0 ppm by volume; and,

(n) Unless otherwise provided in this Agreement, Shipper Gas shall meet the most restrictive quality specifications required from time to time by the facilities receiving Shipper Gas at the Redelivery Points and/or the Interconnecting Pipelines.

APPENDIX A-13

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

(a) Hydrogen Sulphide—not to exceed twenty (20) PPM; and.

(b) Carbon Dioxide—not to exceed five (5%).

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 (i) Gatherer shall give Shipper written notice or 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:

(a) take receipt of the non-conforming Shipper Gas; or

(b) immediately cease receiving the non-conforming Shipper Gas from Shipper by shutting in the sources of such nonconforming 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 Magnolia 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 future, 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.

SECTION 8. MEASUREMENT EQUIPMENT AND PROCEDURES

8.1 Measurement. The quantity and “Gross 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

APPENDIX A-14

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 be 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.

APPENDIX A-15

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:

(a) Accumulated Sample or an On-line Chromatograph – Receipt Points with an average production greater than 50,000 Mcf per Day during the previous six (6) mouths or a current monthly average volume greater than 50,000 Mcf per Day shall utilize either an accumulated sample or on-line chromatograph. 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.

(iv) Plant Inlet samples shall be based on daily readings of Gatherer’s operational data acquisition system.

8.5 Access to Tests and Test Records. Each party shalt have the right to be present at the time of any installing, testing, calibrating or adjusting done in connection with the other’s equipment used in the measurement and sampling of deliveries made available hereunder. Upon written request, the measuring party shall make its hourly measurement information if electronic flow measurement or sampling is used, to the other party for examination, the same to be returned within twenty (20) Days; provided, however, that the measuring party shalt not be required to provide any such charts or information more often than once in any three (3) Month period.

8.6 Preservation of Records. Each party shall preserve for a period of at least twenty four (24) Months copies of all test data, charts and other similar records.

APPENDIX A-16

SECTION 9. PAYMENTS

9.1 Invoices. Gatherer shall provide Shipper with a detailed statement and supporting documentation for all amounts payable by either Party under the terms of this Agreement not later than the twenty-fifth (25th) day of the Month following the Month for which the amounts are due, except as otherwise provided in this Agreement. Shipper shall remit payment thereon to Gatherer as shown on such statement no later than thirty (30) days after such statement is sent to Shipper. In addition, any amounts owed to Shipper under this Agreement shall be paid no later than thirty (30) days after an invoice is sent to Gatherer. Such payment shall be made by wire transfer pursuant to wire transfer instructions delivered by Gatherer to Shipper in writing from time to time. Gatherer’s current wire transfer instructions are as follows:

JPMorgan Chase Bank, Houston, Texas

ABA No. 000000000

For credit to the account of CenterPoint Energy Field Services, Inc.

Account No. 0000-000-0000

9.2 No Netting. Except in the event of a payment default by the other Party, neither Party may net amounts owed to it under this Agreement against amounts owed under any other agreements among the Parties.

9.3 Audit Rights. Either Party, on thirty (30) days prior written notice, shall have the right at its expense, at reasonable times during normal business hours, to audit the books and records of the other Party to the extent necessary to verify the accuracy of any statement, allocation, measurement, computation, charge, or payment made under or pursuant to this Agreement. The scope of any audit shall be limited to transactions affecting Shipper, including aggregated Third Party Gas volumes and Shipper Partner volumes hereunder and shall be limited to the twenty-four (24) calendar month period immediately prior to the calendar month in which the notice requesting an audit was given. However, no audit may include any time period for which a prior audit hereunder was conducted, and no audit may occur more frequently than once each twelve (12) calendar months. All statements, allocations, measurements, computations, charges, or payments made in any period prior to the twenty-four (24) calendar month period immediately prior to the calendar month in which the audit is requested or made in any twenty-four (24) calendar month period for which the audit is requested but for which a written claim for adjustments is not made within ninety (90) days after the audit is requested shall he conclusively deemed true and correct and shall be final for all purposes. To the extent that the foregoing varies from any applicable statute of limitations, the Parties expressly waive all such other applicable statutes of limitations.

9.4 Right to Suspend on Failure to Pay.

(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

APPENDIX A-17

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 (1) 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 dare payment is due until the date payment is made.

SECTION 10. FORCE MAJEURE

10.1 MI 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

APPENDIX A-18

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 Magnolia Gathering System, as the case may be, and the impact of Shipper’s Force Majeure condition on downstream allocations.

SECTION 11. LIABILITY AND INDEMNIFICATION

11.1 Shipper Liability and Indemnification.

Revised Gathering Fee Calculations

Upon an Expansion Request by a Shipper pursuant to Section 6, the Gathering Fee will be re-calculated 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 EOR or WOR System Capacity (as the case may be) resulting from the Expansion (the “Applicable Base Fee”). If Expansion Capacity includes EOR and WOR Expansions, the Applicable Base Fee shall be the lower of the respective Base Fees identified in the EOR and WOR tables below, irrespective of the resulting EOR or WOR System Capacities; unless simultaneous expansions are made, then the applicable Base Fee in the Simultaneous Expansion Table below applies. Unless otherwise agreed, Expansions shall be made in multiples of 100 MMcf/d up to 500 MMcf/d for each system, EOR and WOR, 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.

Whereas the Revised Gathering Fee will be calculated as follows:

(a) The Revised Gathering Fee =

(i) The sum of:

Initial Capacity*Applicable Base Fee +

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 of either the FOR or WOR system, whichever system generated the Applicable Base Fee, except in the case of a simultaneous expansion of the WOR and EOR Systems. Where there is a simultaneous Expansion of the EOR and WOR Systems, the total System Capacity shall include the total capacity of each system including expansion volumes for both WOR and FOR Systems.. 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:

Inflator = 1 + (Future Cost Index – Initial Cost Index) * 75%

Initial Cost Index

Where “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 12-month period prior to August 2009.

Where the “Future Cost Index” is the average of the Cost Index for the 12-month period immediately prior to the month the election of incremental capacity was made. 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.

F-2

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

Year 1 – 200 MMcf/d EOR, 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 EOR, assumed Future Cost Index is 10% higher than the Initial Cost Index for purposes of example =10%

Year 3 – 200 MMcf/d EOR, 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 EOR System is expanded by 200 MMcf/d increasing the EOR System Capacity to 700 MMcf/d is calculated as follows:

Applicable Base Fee = [***]

Revised Gathering Fee = [***]

Revised Gathering Fee = [***]/MMBtu; the Revised Gathering Fee applies to Gas flowing on both the EOR and WOR Systems

The Revised Gathering Fee for Year 2, where the EOR System is expanded by an incremental 100 MMcf/d increasing the EOR System Capacity to 800 MMcf/d is calculated as follows:

Applicable Base Fee = [***]

Revised Gathering Fee after 1st Expansion of [***]

Revised Gathering Fee for 2nd Expansion – [***]

Revised Gathering Fee = [***] MMBtu; the Revised Gathering Fee applies to Gas flowing on both the EOR and WOR Systems

The Revised Gathering Fee for Year 3 where, the EOR System is expanded by an incremental 200 MMcf/d increasing the FOR System Capacity to 1,000 MMcf/d is calculated as follows:

Applicable Base Fee = [***]

Revised Gathering Fee for 1st Expansion of [***]

Revised Gathering Fee for 2nd Expansion of incremental [***]

F-3

Revised Gathering Fee for 3rd Expansion = [***] Revised Gathering Fee = [***]/MMBtu; the Revised Gathering Fee applies to Gas flowing on both the EOR and WOR Systems.

Example, illustrating Revised Gathering Fee Calculation for Simultaneous Expansions:

If a simultaneous expansion of 400 MMcf/d occurs for both WOR and EOR, 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%

The Revised Gathering Fee is calculated as follows:

Applicable Base Fee = [***]

Revised Gathering Fee for WOR and EOR after Expansion of 400 MMcf/d (each side) = [***]

Revised Gathering Fee = [***]/MMBtu; the Revised Gathering Fee applies to Gas flowing on both the EOR and WOR Systems

GUARANTY

THIS GUARANTY is made this 1st day of September, 2009 (the “Effective Date”) by CenterPoint Energy, Inc. (“Guarantor”), to and for the benefit of EnCana Oil & Gas (USA) Inc., and its successors and assigns (“EnCana”) under that certain Gas Gathering and Treating Agreement (the “GGA”) dated September 1, 2009 between EnCana, as Shipper, and CenterPoint Energy Field Services, Inc., a subsidiary of Guarantor, as Gatherer (“CEFS”) relating to the provision of gathering and treating services with respect to natural gas produced by EnCana in Red River and DeSoto Parishes, Louisiana.

WITNESSETH:

For good and valuable consideration, the receipt and adequacy of which are acknowledged by Guarantor, including, without limitation, the benefits that Guarantor will derive from CEFS’s entry into the GGA, Guarantor agrees as follows:

Subject to and not exceeding the Maximum Guaranty (defined below), Guarantor hereby unconditionally and irrevocably guarantees to EnCana (a) to fund CEFS’ obligations under the GGA and (b) the punctual payment in full of any and all financial obligations, including, without limitation, those relating to indemnity, due and payable to EnCana under the GGA (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 EnCana, 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 EnCana in enforcing any rights under the GGA or this Guaranty. Unless otherwise specifically defined in this Guaranty. defined terms herein shall have the meaning ascribed to them in the GGA.

Guarantor’s maximum obligation under this Guaranty with respect to the Obligations (the “Maximum Guaranty”) shall be the sum of the Initial Guaranty Amount. the Expansion Capacity increment Guaranty Amounts, and Additional Services Guaranty Amounts, as such amounts may change from time to time, and as such amounts are calculated below:

Initial Guaranty Amount. As of the Effective Date, Guarantor guarantees to EnCana the Obligations up to Two Hundred Million U.S. Dollars (U.S. $200,000,000.00) of the Obligations (“Initial Guaranty Amount”). Effective on the Gathering System Completion Date, the Initial Guaranty Amount shall become Fifty Million U.S. Dollars (U.S. $50,000,000.00) until this Guaranty terminates.

H-1

Expansion Capacity Increment Guaranty Amounts.

Pursuant to Section 6 of the GGA, as such Section may be modified from time to time, EnCana may notify CEFS through “Expansion Capacity Requests” to expand the capacity of CEFS’ Magnolia Gathering System.

ii.

For each 100 MMcf per day increment in any Expansion Capacity Request made by EnCana pursuant to Section 6.1 of the GGA, as such Section may be modified from time to time, Guarantor’s Maximum Guaranty pursuant to this Guaranty shall increase by Thirty-Five Million U.S. Dollars (U.S. $35,000,000.00) (each an “Expansion Capacity Increment Guaranty Amount” and collectively the “Expansion Capacity Increment Guaranty Amounts”).

iii.

Guarantor’s guarantee to EnCana with respect to the Obligations up to each Expansion Capacity increment Guaranty Amount shall commence on the effective date of the applicable Expansion Capacity Request and terminate upon completion of the construction and installation of the corresponding Expansion Capacity facilities. An example of a calculation of the Maximum Guaranty is provided in Schedule 1 to this Guaranty.

iv.

For each Expansion Capacity Increment Guaranty Amount, such Amount shall be increased above $35 million on the date EnCana notifies CEFS of the Expansion Capacity Request, using the formula for the Inflator provided for in Exhibit F of the GGA to calculate the Revised Gathering Fee, such Inflator to be calculated as of the date of the request.

Additional Services Guaranty Amount.

Pursuant to Section 7 of the GGA, as such Section may be modified from time to time. EnCana may request CEFS to provide Additional Services or Additional interconnections on CEFS’ Magnolia Gathering System, following which request CEFS shall provide to EnCana a proposal for such Additional Services or Additional Interconnections and the Additional Gathering Fee in connection therewith (an “Additional Services Proposal”).

ii.

For each accepted Additional Services Proposal, Guarantor’s Maximum Guaranty pursuant to this Guaranty shall increase by the amount of the capital expenditure used to perform the calculation of the Additional Gathering Fee pursuant to the formula in Exhibit G of the GGA (each an “Additional Services Guaranty Amount” and collectively the “Additional Services Guaranty Amounts”).

iii.

Guarantor’s guarantee to EnCana of the Obligations up to each Additional Services Guaranty Amount shall commence on the effective date of EnCana’s notice under Section 7.2(x) of the GGA to commence construction of the Additional Services requested and terminate upon completion of the construction and installation of the corresponding Additional Services facilities.

H-2

Other Cost Increases.

In the event that EnCana reasonably believes that CEFS’ costs for the Initial Build or any Expansion Capacity or Additional Services may be materially in excess of the respective Maximum Guaranty provided pursuant to sections 2.a, 2.b, or 2.c, then EnCana may request, and Guarantor hereby agrees, to negotiate in good faith an increase in the respective Maximum Guaranty to provide a revised Maximum Guaranty which revised Maximum Guaranty would approximate the anticipated cost of the respective construction project (i.e., the Initial Build, the Expansion Capacity, the Additional Services, respectively); provided, however, unless mutually agreed between Guarantor and EnCana, Guarantor shall not be obligated to increase the Maximum Guaranty.

Decreases in Maximum Guaranty Due to Capital Expenditures Made by CEFS.

If Guarantor reasonably believes that the Maximum Guaranty may be materially in excess of CEFS’s remaining capital expenditures for completion of the Initial Build, Expansion Capacity and Additional Services provided for in section 2.a, 2.b, or 2.c, then Guarantor may request, and EnCana hereby agrees, to negotiate in good faith a decrease in the Maximum Guaranty to provide a revised Maximum Guaranty which revised Maximum Guaranty would approximate the remaining anticipated capital expenditures for the respective construction projects (i.e., the Initial Build, the Expansion Capacity, the Additional Services, respectively); provided, however, unless mutually agreed between Guarantor and EnCana, EnCana shall not be obligated to decrease the Maximum Guaranty.

EnCana may, in its sole and absolute discretion, without notice to or consent by Guarantor, and without in any way releasing, altering, impairing, or discharging the obligations and liabilities of the Guarantor under this Guaranty, from time to time (a) waive compliance with or any default under the provisions of the GGA; (b) enter into such modifications, extensions, amendments, supplements, or other agreements respecting the GGA as CEFS and EnCana may deem appropriate, whereupon Guarantor shall continue to be fully liable hereunder for the Obligations of CEFS under the GGA as so modified, extended, or amended; (c) effect any release, compromise, or settlement in connection and compliance therewith; or, (d) accept, release or discharge any other person as a guarantor of any or all of CEFS’s Obligations.

The obligations of the Guarantor hereunder (a) shall be absolute and unconditional, irrespective of any change in the time, manner, or place of payment of any of the Obligations, or any other amendment or waiver of or any consent to departure from or termination of the GGA; (b) shall be primary, immediate, and direct; (c) shall not be conditioned upon the pursuit by EnCana of any remedy Which it may have against CEFS or any other person with respect to the GGA; and (d) shall not be diminished or relieved by the release or discharge of CEFS in any creditors, receivership, bankruptcy, or other proceedings, the impairment, limitation, or modification of the liability of CEFS or the estate of CEFS in bankruptcy or of any remedy for the enforcement of CEFS’s liability

TO GUARANTY DATED SEPTEMBER 1, 2009 BY CENTERPOINT ENERGY, INC. TO

AND FOR THE BENEFIT OF ENCANA OIL & GAS (USA) INC.

(Example of Calculation of Maximum Guaranty)

If EnCana requests expansion of the capacity of the Magnolia Gathering System of 200 MMcf per day on the West side of the Red River, the corresponding Expansion Capacity Increment Guaranty Amount will be $70 million. If EnCana then provides an Expansion Capacity request for an additional 100 MMcf per day on the East side of the Red River, the Expansion Capacity Increment Guaranty Amount will increase to a total of $105 million. If CEFS thereafter completes the facilities that accommodate only one of the 100 MMcf per day increments, the Expansion Capacity Increment Guaranty Amounts shall decrease from $105 million to $70 million as of the date the 100 MMcf per day Expansion is completed.
