In the event a change in delivery or receipt is necessary, the Party requiring the change shall provide the other Party with at least twenty-four (24) hours notice of such change through normal scheduling procedures.

ARTICLE 9

PROCESSING

9.1 Processor agrees to process, treat and/or condition at Processor’s Panola County Gas Processing Plants (collectively, the “Plant”) up to a varying amount of gas per day (the “Capacity Commitment”) produced from the Dedicated Wells described in Exhibit A as well as other gas owned or controlled by Producer and delivered by or on behalf of Producer to Processor at the Receipt Point(s) up to the capacity limitations set forth herein. The Capacity Commitment shall initially be set at ** Mcf per day, which shall remain in force for a period of ninety (90) days and thereafter shall be established based on ** of the daily average of the actual volumes of Producer’s Gas delivered to Processor at the Receipt Point(s) during each ninety (90) day rolling period, which Capacity Commitment shall never exceed ** Mcf per day, nor shall the capacity commitment ever fall below ** Mcf per day. An example of the Capacity Commitment is set forth below:

Any volumes of Producer’s Gas delivered by Producer to Processor above the applicable Capacity Commitment may be processed by Processor on an interruptible basis and only if Processor has available capacity in its Plants.

9.2 Processor agrees to deliver to Producer, Producer’s share of Plant Products at the tailgate of the Plant (the “Plant Product Delivery Point”) based on the fixed recovery percentages listed below and, in exchange for the payment by Producer to Processor of the Plant Product Transportation Fee set forth in Exhibit B. For the purpose of this Agreement, the fixed liquid hydrocarbon recovery percentages (“Fixed Recovery Percentages”) are as follows:

6

SPECIFIC TERMS IN THIS EXHIBIT HAVE BEEN REDACTED BECAUSE CONFIDENTIAL TREATMENT FOR THOSE TERMS HAS BEEN REQUESTED. THE REDACTED MATERIAL HAS BEEN SEPARATELY FILED WITH THE SECURITIES AND EXCHANGE COMMISSION, AND THE TERMS HAVE BEEN MARKED AT THE APPROPRIATE PLACE WITH TWO ASTERISKS (**).

The foregoing Fixed Recovery Percentages are based on the condition that the Btu content of Producer’s Gas delivered at the Receipt Point is at least ** Btus. In addition to the fees set forth in Exhibit B, (i) if at any time the daily average Btu content of Producer’s Gas averaged over a particular Monthly period is below ** Btus but greater than ** Btus, Producer agrees to pay to Processor an additional fee of ** per MMbtu for all gas processed during such particular Month, which fees shall be in addition to the fees set forth in Exhibit B, and (ii) if at any time the daily average Btu content of Producer’s gas averaged over a particular Monthly period is below ** Btus but greater than ** Btus, Producer agrees to pay Processor an additional fee ** per MMbtu, which fees shall be in addition to the fees set forth in Exhibit B. If at any time the daily average Btu content of Producer’s Gas is less than ** Btus, Processor shall not be required to process Producer’s Gas until such time as Producer’s Gas exceeds ** Btus and is reasonably expected to exceed such Btu content during the remaining period of the particular Month. In such event, Producer and Processor shall meet to discuss the type of services that Processor can provide to Producer in order to make Producer’s Gas merchantable but no such services shall be performed until the Parties mutually agree on the services to be provided and the fees to be charged by Processor in providing such services. If the parties cannot agree within thirty (30) days on the services to be provided or the fees to be charged, then either party shall have the right to terminate this Agreement, however, Producer will remain liable for any Deficiency Payment(s) as set forth in Article 3 above.

9.3 Plant Products shall mean all liquefiable hydrocarbons extracted and saved at the Plant attributable to Producer’s Gas based on the Plant Inlet Volume; and the quality of Producer’s Gas delivered to Processor at the Receipt Point based on the Fixed Recovery Percentages shown above. Such liquefiable hydrocarbons shall include ethane, propane, butanes, and natural gasoline, as a mixture.

9.4 The Plant Product Delivery Point and Plant Product custody transfer point shall be at the interconnection between Processor or it’s affiliate’s natural gas liquid facilities, which are connected to the tailgate of the Plants, and the Panola Pipeline. The Plant Product Delivery Point shall be deemed to be located at the downstream riser of Panola Pipeline’s meter station located at the interconnection point between Processor’s natural gas liquids facilities and the Panola Pipeline. The parties shall each provide copies or otherwise make available to the other party any Plant Product volume allocation statements or Plant Product measurement statements and revisions thereof in connection with the Plant Products related to this Agreement that either party may reasonably require in carrying out the provisions of this Agreement.

9.5 Producer agrees to arrange, at its sole cost and expense, for adequate downstream facilities to accept delivery of Producer’s allocated share of Plant Products. Processor shall follow or cause to be followed all reasonable delivery instructions given by Producer or its designee with respect to Producer’s Plant Products, but it is understood between Processor and Producer that Processor

shall make no special arrangements nor incur any additional costs or expenses in the disposition of Producer’s Plant Products unless otherwise mutually agreed to between Producer and Processor. Since Producer and Processor and potentially other third parties shall each have Plant Products owned and/or controlled by them at the tailgate of the Plant, in the event of curtailment on any downstream liquid pipelines utilized to transport Plant Products, each of Processor, Producer and such third parties shall be curtailed based on the allocation methodology utilized by such downstream pipeline and if there are no such curtailment priorities established by such pipelines, shall be allocated based on the percentage of Plant Products owned by Processor, Producer and each of such third parties.

9.6 Should Producer have any problem with the disposition of Producer’s Plant Products and/or Residue Gas due to Force Majeure, loss of market, or other reasons beyond the reasonable control of Producer, Processor shall have the right to curtail receiving gas at the Receipt Point as long as Producer’s problem exists.

Producer shall have the right to require the meters to be calibrated at any time, but calibrations made at Producer’s request shall be at the expense of Producer unless the percentage of inaccuracy is found to be ** or more, in which case the calibration shall be made at the expense of Processor. Readings, calibrations, and adjustments of the EFM equipment shall be done only by Processor or its agent, but all data with respect thereto shall at all reasonable times be available to Producer for inspection. If, upon any test, the percentage of inaccuracy shall be ** or more, registrations thereof shall be corrected at the rate of such inaccuracy for any period which is definitely known or agreed upon, but in case the period is not definitely known or agreed upon, then for a period extending back one-half (1/2) of the time elapsed since the last date of calibration. No correction shall be made for recorded inaccuracies of less than ** Processor shall cause metering equipment found inaccurate to be immediately restored to a condition of accuracy. If for any reason any meter is out of service or out of repair, such that the amount of Producer’s Gas received cannot be ascertained or computed from the reading thereof, the amount of Producer’s Gas received during the period such meter was out of service or out of repair shall be estimated based upon the best data available, using the first of the following methods which is feasible:

11.8 Each Party shall have the right to be present at the time of installing, reading, cleaning, changing, repairing, inspecting, testing, calibrating or adjusting done in connection with the other’s measuring equipment in measuring receipts hereunder. The records from such measuring equipment shall remain the property of their owner, who shall keep them on file for a period of not less than two (2) years, but upon request, each will submit to the other its records and charts, together with calculations therefrom subject to return within fifteen (15) days after receipt thereof.
