ARTICLE VI
RESERVATIONS OF PRODUCER

1) Producer reserves the right to withhold from delivery any gas as the lessee is required to deliver to its lessors under the terms of the Lease(s) subject to this Contract.

2) Producer may, at any time, without liability to Processor or to Producer, clean out, deepen, shut-in, or abandon any well(s) on Producer’s Leases, or may use any efficient, modern or improved method for the production of gas; provided however, that before any well(s) are taken out of service for any reason, Producer agrees to first shut-off the well(s) connection with Processor’s gas gathering lines.

3) Producer reserves the right to pool, combine and unitize Leases hereunder with other properties and alter the pooling combination or units; in which event, this Contract will cover Producer’s allocated interest in the unitized production insofar as that interest is attributable to the Leases covered by this Contract.

4) Producer reserves the right to the Return Volume attributable to each Producing Unit for use within the Producing Unit.

ARTICLE VII
RIGHT OF WAY

To the extent Producer’s Lease(s) permits, Processor is granted the right to lay and maintain lines and to install any equipment on the Lease and shall have the right to free entry for purposes incidental to Processor’s operations so long as those purposes do not interfere with Lease operations or the rights of owners in fee. All line and other equipment placed by Processor

on the Lands shall remain the property of the Processor and may be removed by Processor at any time.

ARTICLE VIII
METERS AND COMPUTATIONS OF VOLUMES

1) All gas delivered hereunder shall be measured by a suitable orifice meter or meters of standard make, or by other facilities or methods accepted as accurate by the industry, or as mutually agreed to by both Producer and Processor, to be furnished, installed, operated and kept in repair by Processor at each Delivery Point. Processor shall, in addition, pay for all tests provided for in this ARTICLE VIII, unless otherwise stated. However, Producer may, at its expense, install and operate meters to check Processor’s meter provided that the check meter installation in no way interferes with the proper operation of Processor’s meter. The computation of all gas volumes measured by orifice meters shall be based on the latest basic flange tap orifice factors published by the American Gas Association corrected to a base pressure of 14.73 pounds per square inch absolute and to a base temperature of sixty degrees Fahrenheit (60°F), using either an assumed atmospheric pressure of 12.7 pounds per square inch absolute (regardless of actual atmospheric pressure at which the gas is measured), or actual atmospheric pressure depending on the type of measurement that Processor utilizes. No correction shall be made for any variation of the flowing temperature from the base temperature. The Reynold’s Number Factor and the Expansion Factor shall be one.

2) The specific gravity of the gas shall be determined by spot tests analyzed by gas chromatography, or by other methods as shall be agreed upon. The specific gravity shall be determined at least once each six (6) months, or as often as either party requests, provided that tests more frequent than once every six (6) months shall be paid for by the party requesting the test. The results obtained from each test shall be the specific gravity of the gas delivered until the next test is made.

3) At least once each six (6) months, Processor shall verify the accuracy of its measuring equipment. If either party shall notify the other that it desires a special test on any measuring equipment, the parties shall cooperate to secure a prompt verification of the accuracy of the equipment. Processor shall give Producer notice of the time of all tests of meters reasonably in advance of, but in no event less than ten (10) days prior to the conduct of such test in order that the Producer may conveniently have its representative present. Cost of special tests shall be borne by the party requesting them if measuring equipment is found to be registering accurately. In the event a meter is out of service or in the event that either Processor or Producer finds that a meter is registering inaccurately, the volume of gas delivered hereunder shall be estimated by the first of the following methods which is feasible:

	a.		Using the registration of any check meter or meters if installed and accurately registering, or

	b.		By correcting the error if the percentage of error can be accurately ascertained by calibration or mathematical computation, or

Determining the volume of gas delivered during any such period when meter is out of service or registering inaccurately by multiplying the number of barrels of oil produced ruing such period from the xxxxx from which gas is delivered through the meter by the average volume of gas delivered hereunder per barrel of oil produced during the ninety (90) day period to the last test of the meter reflecting accurate measurement.

4) If, upon rest, any measuring equipment is found to be in error of more than two percent (2%), then the equipment shall be adjusted to record correctly, and any previous recordings of that equipment shall be corrected to zero error for any period which is known definitely or agreed upon or, if the period is not definitely known, the correction shall be for a period extending over one-half of the time elapsed since the last preceding test. The meter or meters shall be open to inspection at all times by Producer in the presence of Processor. Processor shall preserve for a period of two (2) years all test data, charts and other similar records for auditing. Thereafter same shall conclusively be deemed to be true and correct. If requested, Processor shall send the meter charts to Producer for inspection, after which they shall be returned to Processor within sixty (60) days following receipt by Producer.

ARTICLE IX
DETERMINATION OF COMPOSITION

Representative determinations for acid gases and propane and heavier hydrocarbon content shall be determined by Processor by gas chromatography, or other industry accepted methods for determining the composition of the gas, including acid gas content, at least once every six (6) months, or as often as either party to the Contract requests; provided, that tests more frequent than once every six (6) months shall be paid for by the party requesting same. These tests and measurements shall be the basis for determining the price for gas purchased.

ARTICLE X
ALLOCATION OF LIQUID PRODUCTS AND RESIDUE GAS

1) That portion of each liquid Plant Product produced at Processor’s Plant which is attributable to each Delivery Point shall be determined by multiplying the total Plant production of that Plant Product by a fraction, the numerator of which is the theoretical gallons of the Plant Product in Producer’s gas at the Delivery Point and the denominator of which is the theoretical gallons of the Plant Product attributable to all points delivering gas to Processor.

2) Theoretical gallons of the Plant Product attributable to each Delivery Point shall be computed by multiplying Producer’s gas volume delivered into Processor’s gathering system at each Delivery Point by the applicable content (GPM) for that meter location for the Accounting Period. The theoretical gallons of that Plant Product attributable to all gas processed in the Plant shall be the summation of the theoretical gallons of those Plant Products attributable to all delivery points.

3) That portion of Residue Gas Heating Value at Processor’s Plant which is attributable to each of Producer’s Delivery Points shall be determined by multiplying the total

Gas Heating Value of Residue Gas delivered by Processor at the outlet of Processor’s plant by a fraction, the numerator of which shall be the Gas Heating Value delivered to Processor’s gathering system at each Delivery. Point, less that Delivery Point’s share of the Product Heating Value of Plant Products allocated to the Delivery Point, Plant fuel Gas Heating Value, and field compression fuel Gas Heating Value, and the denominator of which shall be the total of all Gas Heating Value delivered at all points delivering gas to Processor, less the total Product Heating Value of all Plant Products, Plant fuel Gas Heating Value and field compression fuel Gas Heating Value attributable to all points delivering gas to Processor.

4) That portion of Plant fuel Gas Heating Value attributable to each Producer’s Delivery Point shall be determined by multiplying the total Plant fuel Gas Heating Value by a fraction, the numerator of which is the amount of liquid products allocated to each Delivery Point, and the denominator of which is the total amount of liquid products from all points delivering gas to Processor.

5) That portion of field compressor fuel Gas Heating Value attributable to each Delivery Point utilizing the field compressor shall be determined, for each field compressor, by multiplying the total field compressor fuel Gas Heating Value, for that field compressor, by a fraction, the numerator of which is the Producer’s gas volume delivered at each Delivery Point utilizing that field compressor and the denominator of which is the total volume of gas delivered at all points delivering gas to Processor utilizing that field compressor.

ARTICLE XI
PRICE

The price paid to Producer at the Delivery Point for 100% of the gas is shown in Paragraph 1) below.

1) Processor shall pay Producer an amount equal to forty percent (45%) of the “Current Actual Net Value” of that portion of all Plant Products saved and sold at Processor’s. Plant which are attributable to Producer’s gas purchased hereunder, plus an amount equal to seventy-five percent (75%) of the “Net Sales Proceeds Received for Residue Gas” attributable to Producer’s gas purchased hereunder that is in excess of Producer’s Return Volume, this compensation entitling Processor to use sufficient gas for Plant fuel free of additional cost.

In the event that Processor acquires additional gas commitments from any party(s) equal to or greater than fifteen percent (15%) of the gross interests in the Production Units covered by this Agreement, the payment percentage applicable to Plant Products above shall be increased from forty-five percent (45%) to fifty percent (50%).

(i) The “Current Actual Net Value”of each Plant Product shall, for each Accounting Period, be obtained by multiplying the “Current Weighted Average Net Sales Price”of the Plant Product by the number of gallons thereof produced and sold from Processor’s Plant by Processor.

(ii) The “Current Weighted Average Net Sales Price” of each Plant Product shall be determined by dividing the total gallons of that Plant Product produced and sold during

the Accounting Period into the “Net Proceeds F.O.B. Plant II received from sales of the Plant Products for each period by Processor.

(iii) “Net Proceeds F.O.B. Plant II shall be the total gross proceeds received by Processor from the sale of each Plant Product during each Accounting Period, less any charges for tank car rental, taxes (excluding income, franchise and ad valorem taxes), pipeline transportation and fractionation costs and similar costs and expenses incurred or made in connection with the sale, transportation and delivery of such Plant Product.

(iv) “Net Sales Proceeds Received for Residue Gas II means the total proceeds received by Processor, during each Accounting Period, from its residue gas purchaser (s), less any transportation, storage charges or third party fees assessed Processor and required for the disposition of residue gas.

2) In Lieu of receiving payment for Residue Gas, Producer may receive its share of Residue gas in kind at a mutually agreeable point at or near Producer’s lease, for Producer’s use in the development of Producer’s leases committed hereunder. In such case that the total residue gas remaining from gas delivered by a Producing Unit covered hereunder is insufficient in quantity for the purposes of development and operation of said Producing Unit, Processor shall nevertheless deliver sufficient gas to said leases to meet Producer’s development and operating requirements. Such gas shall first be delivered from Producer’s share of available residue gas remaining from other Producing Units covered hereunder. If additional gas is required, Processor agrees to sell such gas to Producer at a price equal to the “Net Weighted Average Sales Price” for all residue gas sold at Processor’s Plant during the month such gas is required plus a fee equal to fifteen cents per MMBtu ($0.15/MMBtu). However, Processor shall not be obligated to provide a volume exceeding 30,000 MCF of gas sales to Producer each month.

Processor shall deduct any gas sales made to Producer hereunder from payments otherwise due to Producer hereunder.

3) For any gas delivered hereunder containing in excess of one quarter (1/4) grain of H₂S per one hundred standard cubic feet (100 SCF) or in excess of three percent (3%) by volume CO₂, Producer will be charged a base treating fee of $0.030 per MCF plus a variable fee of $0.056 per MCF for each mole percent of total acid gas content in excess of three percent (3%). Any fractional portion of a mole percent acid gas shall bear its proportionate share of the variable treating fee. The total treating fee above shall be adjusted from payments otherwise due Producer hereunder. Any fractional portion of a mole percent acid gas will bear its proportional part of the $0.056 variable treating fee. The treating fee indicated above shall be adjusted each month by multiplying a factor, the numerator of which shall be the most current Producer Price Index for Oil and Gas Field Service (SIC 138) as published by the U. S. Department of Labor and the denominator of which shall be said Price Index as published for the month in which gas was first delivered into Processor’s gathering system under this Gas Sales and Purchase Contract. Under no circumstances will the treating fee be less than the fee shown above. Processor shall deduct any and all treating fee due hereunder from payments otherwise due Producer hereunder.

4) Subject to the conditions hereof, Producer, at this option, may take, in-kind, the applicable percentage specified in Paragraph 3 of this ARTICLE XI, above, of the liquid

products which are attributable to Producer’s gas purchased hereunder in lieu of receiving that percentage of the “Current Actual Net Value” received for those Liquid Products. Provided, however, should Producer elect, Producer shall make its election by giving Processor at least sixty (60) days advance written notice of that election. Any election shall take effect at the expiration of any then existing Plant product sales contracts and shall be for a minimum period of one (1) year, unless the parties agree to the contrary. Any additional expenses incurred by virtue of Producer’s taking in-kind shall be paid by Producer. Should Producer elect to take in-kind, Producer shall only be entitled to utilize its proportionate part of Plant storage capacity; and, should Producer utilize more than its proportionate share of storage, Processor shall have the right, without notice to Producer, to dispose of the Plant Products utilizing more than Producer’s proportionate share of storage and remit to Producer the “Net Proceeds F.O.B. Plant” for those Plant Products. Further, should Producer elect to take in-kind, it shall not cease taking in-kind until it has first provided ninety (90) days advance written notice to Processor of its decision to cease taking in-kind and then Producer shall not be permitted to resume taking those Plant Products in-kind for a period of six (6) months following the date it ceased taking in-kind. Producer’s resumption of taking in-kind shall be subject to the notice requirements provided above.

ARTICLE XII
DRIP

The Processor shall keep its Gathering System, reasonably clear of obstruction and the hydrocarbon liquids, “Drip”, collected in that System shall be owned by Processor.

ARTICLE XIII
TITLE

1) Producer warrants title to all gas delivered to Processor and that it has good right to sell that gas to Processor. If the title to gas delivered by Producer hereunder is questioned or is involved in any legal action, Processor shall have the right to withhold payment, to the extent of the interest questioned or involved in legal action, during the pendency of the action or until title is freed from the question, or until Producer furnishes, or causes to be furnished, bond conditioned to save Processor harmless from all claims arising out of the question or action, with surety acceptable to the Processor.

2) Notwithstanding anything in this Contract to the contrary, it is agreed and understood that Processor shall not .be required to disburse any payments due for gas sold hereunder until Producer furnishes Processor with a division order executed by Producer, based upon a title opinion prepared by an attorney on behalf of Producer and supplied to Processor at no expense to Processor which division order specifically describes Producer’s gross working interest in the gas sold hereunder, on a well by well basis, and specifically indemnifies Processor against and holds Processor harmless from any and all claims made by any party due to Processor’s disbursement of proceeds in accordance with that division order.

3) Processor acknowledges that as of the date of this Contract Producer is in a pay status and that, absent a title dispute, no additional title option for currently producing properties is required.

ARTICLE XIV
ROYALTY AND TAXES

Producer agrees to pay, or cause to be paid, all taxes and assessments lawfully levied and imposed upon Producer with respect to the gas delivered hereunder prior to its delivery to Processor. Processor agrees to pay, or cause to be paid, all taxes and assessments lawfully levied and imposed upon Processor with respect to the gas delivered hereunder after its receipt by Processor. Neither party shall be responsible or liable for any taxes or other statutory charges levied or assessed against any of the facilities of the other party used for the purpose of carrying out the provisions of this Contract.

ARTICLE XV
FORCE MAJEURE

1) In the event that any party hereto is rendered unable, wholly or in part, by force majeure to carry out its obligations under this Contract, other than the obligation to make payment of amounts due hereunder, upon that party’s giving notice and reasonable full particulars of the force majeure to the other party hereto within a reasonable time after the occurrences of the cause relied upon, the obligations of the party giving the notice, so far as they are affected by the force majeure, shall be suspended during the continuance of the inability, and the cause of the force majeure, as far as possible, shall be remedied with all reasonable dispatch.

2) The term “force majeure”means any cause, or condition not reasonably within the control of the party claiming suspension.

3) The settlement of strikes, lockouts and other labor difficulty shall “be entirely within” the “discretion of the party having the difficulty. The above requirement that any force majeure shall be remedied with all reasonable dispatch shall not require the settlement of strikes, lockouts or other labor difficulty by acceding to the demands of opponents therein when that is inadvisable in the discretion of the party having the difficulty.

ARTICLE XVI
UNPROFITABLE GAS

In the event the purchase of gas from any well(s) from Producers Lease(s), for any reason, becomes unprofitable in Processor’s sole judgment, Processor shall have the right to refuse to take or cease taking the gas so long as such condition exists and no payment will be due hereunder. It is further provided that if, at any time, the purchase of gas from all sources available to. Processor, or if any cause beyond its control shall render the operation of its Plant unprofitable, in Processor’s sole judgment, Processor may cancel this Contract by giving thirty (30) days written notice to Producer.

ARTICLE XVII
MAXIMUM QUANTITIES

During periods when gas production from all the properties connected to Processor’s Plant exceeds the capacity of Processor’s Plant, Processor shall only be obligated to take ratably as to quantity from all lands connected to Processor’s Plant.
