no such governmental authorizations are required, Buyer and Seller shall commence and prosecute with due diligence the construction of such facilities as are necessary to enable it to receive or deliver at the Delivery Point(s) the specified quantities of gas contemplated by this Contract.  The delivery and receipt of gas shall begin promptly after completion of the construction and installation of connecting facilities.  In the event that either party has not commenced the construction of its facilities within sixty (60) days of the date herein required, or in the event either party commences construction but thereafter fails to prosecute construction with due diligence until completion thereof, the other party shall have the right to cancel this Contract at any time thereafter by serving ten (10) days written notice on the dilatory party unless such dilatory party within said ten (10) days, remedies the cause of such cancellation.

3.2                               Seller, at its sole cost and expense, shall construct, install, maintain, and operate any and all facilities and equipment necessary for the proper, safe and efficient operation of Seller’s wells and to enable it to make delivery of gas hereunder to Buyer at the Delivery Point(s).  Such equipment shall include the valves and fittings necessary to permit Buyer to make its connection at the Delivery Point(s).

3.3                               Buyer, at its sole cost and expense, shall construct, install, maintain and operate any and all facilities and equipment necessary to accept Seller’s gas at each Delivery Point.

3.4                               Insofar as Seller’s lease permits, Buyer or Buyer’s designee is granted the right to lay and maintain lines and install any equipment on the dedicated lease(s) necessary for the receipt of Seller’s gas, and Buyer or Buyer’s designee shall have the right of free entry thereon during the term of this Contract.  Should Buyer be delayed in securing any additional right-of-way not covered hereby, then such delay shall suspend performance under this Contract until such right-of-way may be obtained.  In the event any right-of-way necessary for the receipt of Seller’s gas at any given Delivery Point cannot be obtained on terms and conditions acceptable to Buyer, then Buyer shall not be obligated to connect said Delivery Point.

ARTICLE IV

DELIVERY POINT(S) AND PRESSURE

4.1                               The Delivery Point(s) hereunder shall be the upstream flange of Buyer’s metering facility serving Seller’s Central Tank Battery(s) and/or well(s) (“Delivery Point”).  Upon delivery, title to the gas and all components thereof shall pass to and vest in Buyer.

4.2                               The gas to be delivered hereunder shall be delivered by Seller at the Delivery Point(s) specified in Article 4.1 hereof at a pressure sufficient to enable it to enter Buyer’s facilities against the working pressure therein at reasonable uniform rates of delivery.  Buyer will endeavor to maintain a suction pressure at Buyer’s CTB compression facilities of no greater than forty (40) psig.  Provided, however, with respect to the Coyote Creek CTB, Sunny Slope CTB, Walter CTB, Eagon CTB and/or

5

other CTB producing less than 1 MMCFD, Seller acknowledges that the line pressures will exceed forty (40) psig, but be less than sixty (60) psig, until such time as sufficient volumes are produced by these delivery points to justify the installation of CTB compression by Buyer at these locations, at its sole discretion.  However, in the event Buyer’s line pressure prevents Seller’s gas from being delivered into Buyer’s facilities, Seller shall have the right to flare or otherwise dispose of its gas without penalty or liability to Buyer.  Nothing in this agreement shall be interpreted to require or impose an obligation on Seller to curtail or limit its crude oil production from the Dedicated Leases.

4.3                               The parties hereto acknowledge that at least eighty percent (80%) of the plant and field compression to be utilized by Seller will be operated on electric power.

4.4                               If Seller’s wells become incapable of delivering into facilities owned and/or operated by Buyer, Seller shall so advise Buyer in writing.  Neither party shall be obligated to compress such gas but either party shall have the option to do so.  If either party provides compression facilities, then such party agrees to provide sufficient pulsation dampening equipment so that measurement at the Delivery Point(s) will not be affected by pulsation.

ARTICLE V

SELLER’S RESERVATIONS

5.1                               Seller hereby expressly reserves unto itself, its successors and assigns, the following rights with respect to its interests in the oil and gas properties committed by Seller to Buyer hereunder together with sufficient gas produced therefrom to satisfy such rights:

a.                                       To operate Seller’s oil and gas properties free from any control by Buyer in such manner as Seller, in Seller’s sole discretion, may deem advisable, including, without limitation the right, but never the obligation, to drill new wells, to repair and rework old wells, renew or extend, in whole or in part, any oil and gas lease covering, in whole or in part, the oil and gas properties and to abandon any well or surrender any such oil and gas lease, in whole or in part, when no longer deemed by Seller to be capable of producing gas in paying quantities under normal methods of operation.

b.                                      To use gas produced from the oil and gas properties for developing and operating Seller’s oil and gas properties committed hereto in the field in which the gas is produced, for the operation of Seller’s pipelines, water stations, camps and other miscellaneous uses incident to the operation of such leases, and to fulfill obligations to Seller’s Lessors therein.

6

c.                                       To pool, combine and unitize any of Seller’s oil and gas properties with other properties of Seller and of others in the same field, and to alter such pooling, combination or units, in which event this Contract will cover Seller’s allocated interest in unitized production insofar as such interest is attributable to the oil and gas properties committed hereunder.  Seller shall give notice in writing to Buyer of any change contemplated by this Article as is deemed material to this Contract, and the description of property covered hereby shall be considered as having been amended accordingly.

ARTICLE VI

QUANTITY OF GAS

6.1                             Seller commits all gas produced from the Dedicated Lease(s) to Buyer under this Contract that Seller owns, controls, or has the rights to commit.

6.2                             Buyer will purchase and take Seller’s gas, subject to the demands of Buyer’s resale purchaser(s) and the operating conditions and capacity of the facilities owned and/or operated by Buyer.  It is understood that Buyer cannot guarantee the purchase of any particular quantity of Seller’s gas which is available for sale.

6.3                             Seller shall have the right to dispose of any gas not taken by Buyer, subject to Buyer’s right to resume purchases at any subsequent time.  Buyer shall not have the right to resume purchases of gas if the fees for the taking of said gas as described within this Agreement by Buyer exceeds the revenue received by Seller for same as described within this Agreement.

6.4                             Seller shall have agents or employees available at all reasonable times to receive from Buyer’s dispatchers advice and requests for changes in the rates of delivery of gas hereunder as required by Buyer from time to time.

6.5                             In the event the gas delivered hereunder at any point or points of delivery becomes insufficient in volume, quantity, quality or pressure, in the sole judgment of Buyer, Buyer shall have the right to refuse or cease taking such gas so long as such condition exists, or may terminate this contract as to any such gas upon thirty (30) days notice in writing to Seller.  Seller also has the right to dispose of any gas if the fees for the taking of said gas as described within this Agreement by Buyer exceeds the revenue received by Seller for same as described within this Agreement.

6.6                             The parties hereto recognize the desirability of maintaining the uniform rate of flow of gas to the Plant(s) over each twenty-four (24) hour period in each day throughout each month, and Seller agrees to use its best efforts to regulate its producing schedule so that Seller’s gas shall be made available to the Plant(s) at as uniform a rate of flow as is practicable.

ARTICLE VII

QUALITY OF GAS

7.1                               The gas delivered hereunder shall be commercially free of dust, gum, gum forming constituents, treating chemicals and solid matter that might adversely affect the gathering thereof and shall conform to the following specifications:

7.2                             The acceptance of gas which does not meet the specifications of this Article 7 shall not be deemed a waiver of the right to require future deliveries to conform to said specifications.

ARTICLE VIII

MEASUREMENT AND TESTS

8.1                               Buyer shall operate at or near the point(s) of delivery, an orifice meter, or meter(s).  Seller, insofar as Seller’s leasehold and other mineral rights enable it to do so, will furnish Buyer sites for its metering facilities.  Except as otherwise specifically provided to the contrary in this Article, orifice meters or other measurement devices shall be installed and volumes computed in accordance with accepted industry practice.  Seller shall have access to such metering equipment at reasonable hours, but the reading, calibrating, adjusting, operation and maintenance thereof may be done only by Buyer.

8.2                               The unit of volume shall be one (1) cubic foot of gas at a base temperature of sixty degrees (60°) Fahrenheit and at a pressure base of fourteen and seventy-three hundredths pounds per square inch absolute (14.73 Psia).  Computation of volumes shall be made in accordance with industry accepted practice.

8.3                               In the absence of recording the actual atmospheric pressure, Buyer may assume the atmospheric pressure to be thirteen and two-tenths pounds per square inch absolute (13.2 Psia).  At Buyer’s option the absolute atmospheric pressure may be assumed or may be measured by use of electronic recording devices such as Totalflow

8

(Registered Trademark) or the like.  At Buyer’s option the temperature of the gas passing the meters shall be determined by use of a recording thermometer so installed that it may properly record the temperature of the gas flowing through the meter; otherwise, the temperature shall be assumed to be sixty degrees (60°) Fahrenheit.  The specific gravity shall be determined semi-annually or more often as Buyer deems advisable.

8.4                               Seller may install, maintain and operate, at its own expense, such pressure regulators and check measuring equipment as it shall desire, provided that such equipment shall be installed so as not to interfere with the operation of Buyer’s measuring equipment.  Buyer shall have access to such check measuring equipment at reasonable hours, but the reading, calibrating, adjusting, operation and maintenance thereof shall be done only by Seller.

8.5                               Each party shall have the right to be present at the time of any calibrating done in connection with the other’s metering equipment used in metering deliveries hereunder.  The party proposing a calibration of a meter shall provide written notice to the other party no less than five (5) days prior to the date of the calibration.

8.6                               At time to time as may be necessary Buyer shall verify the accuracy of the measuring equipment and Seller shall verify the accuracy of its check measuring equipment, if any.  If either party shall notify the other that it desires a special test of any measuring equipment, the parties shall cooperate to secure a prompt verification of the accuracy of such equipment.  If either party at any time observes a variation between the delivery meter and the check meter, it will promptly notify the other party thereof and both parties will then cooperate to secure an immediate verification of the accuracy of such equipment.  Each party shall give to the other notice of the time of all tests of meters reasonably in advance of the holding of such tests in order that the other party may conveniently have its representatives present.

8.7                               If at any time any of the measuring or testing equipment is found to be out of service or registering inaccurately in any percentage, it shall be adjusted at once to read accurately within the limits prescribed by the manufacturer.  If any measuring equipment shall be found to be inaccurate or out of service by an amount exceeding two percent (2%) at a recording corresponding to the average hourly rate of flow for the period since the last preceding test, then any previous recordings of such equipment shall be corrected to zero error for any period which is known definitely or agreed upon.  The volume of gas delivered during such period shall be estimated by (i) using the data recorded by and check measuring equipment if registering accurately; (ii) by correcting the error if the percentage of error is ascertainable by calibration, test or mathematical calculation, or if neither such method is feasible; (iii) by estimating the quantity or quality delivered based upon deliveries under similar conditions during a period when the equipment was registering accurately.  No adjustment shall be made for recorded inaccuracies of two percent (2%) or less.

9

8.8                               Buyer shall preserve for a period of at least two (2) years all test data, charts and other similar records.

8.9                               Semi-annually, or more often as Buyer deems advisable, Buyer shall obtain a representative sample of Seller’s gas delivered at each point of delivery and by means of chromatography or other accepted method in the industry determine the composition and gross heating value of Seller’s gas in British Thermal Units (Btu) per cubic foot on a water saturated basis.  The first such determination shall be made within a reasonable time after delivery of gas begins and shall apply until the first day of the month following the next determination.  The period for determination shall be selected by Buyer.  If conditions exist such that Seller desires a Btu determination, Seller will notify Buyer of aforementioned condition and request that a Btu determination be performed.  Buyer shall make such Btu determination within thirty (30) days of receipt of notice from Seller.  If no change is determined from this Btu determination made upon the request of Seller, Seller shall reimburse Buyer for all reasonable costs associated with this Btu determination.

8.10                        The determinations as to conformity of the gas with the above specifications shall be made by Buyer in accordance with generally accepted procedures of the gas industry.  Such determinations shall be made as often as Buyer deems necessary and Seller may witness such determinations or make joint determinations with its own appliances.  If in Seller’s judgment the result of any such test or determination is inaccurate, Buyer, at Seller’s request, will again conduct the questioned test or determination, and the costs of such additional test or determination shall be borne by Seller unless same shows the original test or determination to be materially inaccurate.

8.11                        If any of the gas delivered by Seller hereunder shall fail to meet the quality specifications stated in this Article, Buyer may at its option accept delivery of and pay for such gas or discontinue or curtail Seller’s delivery of gas hereunder whenever the quality of the gas does not conform to the quality specifications.  Buyer shall notify Seller of such failure and Seller shall make diligent effort to deliver gas conforming to the specifications.  If Seller concludes in its sole opinion that it cannot economically deliver gas conforming to the specifications, Seller shall so advise Buyer in writing within thirty (30) days of receipt of deficiency notice from Buyer.  Within thirty (30) days of receipt of such notice from Seller, Buyer shall give notice to Seller in writing of its elections to accept or reject delivery of such gas.  If Buyer rejects delivery of such gas, then said notice will terminate this Contract with respect to such gas.  If Buyer accepts delivery of such gas, Buyer may deduct from the proceeds otherwise payable a fee to cover the reasonable costs incurred by Buyer to monitor the gas quality or to bring the gas within the quality specifications.  Buyer is obligated to notify and receive approval from Seller for any fee(s) to cover reasonable costs incurred by Buyer to monitor the gas quality and/or to bring gas within quality specifications as stated within this section.

ARTICLE IX

ALLOCATION PROCEDURES

9.1                               For each Delivery Point, Buyer shall determine from test data available the theoretical gallons of each Product produced from the Delivery Point.  Buyer will allocate Plant Products actually recovered, saved and sold to each Delivery Point based on the theoretical gallons attributable to the Delivery Point in relation to the total theoretical gallons from all Delivery Points into Buyer’s gathering system.

9.2                               Buyer will allocate field fuel, flare, Plant flare, Plant fuel and Residue Gas used for field compression to each Delivery Point based on the ratio of the wellhead volume for such Delivery Point to the total wellhead volumes from all Delivery Points into Buyer’s gathering system.  However, notwithstanding the above, Buyer retains the right to allocate fuel and flare associated with treating the gas for removal of CO₂ based on the volume of CO₂ in delivery points so treated.

9.3                               Residue Gas returned to the field shall be allocated to each of the Central Tank Batteries and/or wells based upon the actual metered volumes returned to each of the Delivery Points.

9.4                               Residue Gas available for sale at the tailgate of the Plant(s) shall be allocated ratably to each Delivery Point based on the theoretical residue attributable to the Delivery Point in relation to the total theoretical residues from all Delivery Points into Buyer’s gathering system.  Theoretical residue shall be calculated for any Delivery Point by deducting Btu’s of allocated product, fuel and flare from Delivery Point Btu’s.  In addition, Residue Gas available for sale shall also be calculated by deducting any residue gas BTU’s returned to the Central Tank Batteries and/or wells for use by Seller.

ARTICLE X

PRICE

10.1                        As full consideration for the gas and all the components thereof delivered to Buyer hereunder during each month, Buyer shall pay Seller an amount determined by the computations hereunder.  The sale of all Product and Residue Gas by Buyer shall be at a price not less than what Buyer could have received in an arms length third-party transaction.

10.2                        It is understood that the gas delivered hereunder will be gathered in gathering system(s) owned and/or operated by Buyer and may be redelivered to a processing plant or plants for the removal of liquefiable hydrocarbons together with gas produced from other properties.

10.3                        For gas delivered to each Delivery Point hereunder, Buyer shall pay Seller an amount equal to Seller’s allocated gallons of Plant Products (determined as provided in Article 9 above) times fifty percent (50%) times the price actually received by Buyer for the sale of the Product.  In the event Buyer fractionates the Plant Products prior to

11

their sale, buyer shall pay Seller an amount equal to Seller’s allocated gallons of Plant Products (determined as provided in Article 9 above) times fifty percent (50%) of the price actually received by Buyer for the sale of the Product, less a deduction for delivery, transportation, fractionation and sale of four and one-half cents (4.5¢) per gallon.  This fee shall be escalated at the rate of one percent (1%) per year from the Effective Date of this Contract on an annual basis and year-to-year thereafter.

10.4                        Residue Gas available for sale shall be computed in accordance with Section 9.4 of this Contract.  Buyer shall market all the Residue Gas received hereunder and remit to Seller fifty percent (50%) of the proceeds attributable to Seller’s gas.

10.5                        The following fees shall be deducted from the proceeds otherwise due Seller under Sections 10.3 and 10.4 of this Contract:

a.                                   Gathering Fee:              On the first thirty six (36) BCF of Cedar Hills Volumes that are delivered by Seller to Buyer, Buyer shall be entitled to and shall deduct from Seller’s proceeds a fee of sixty cents ($.60) per MCF.   The applicable fee shall be escalated at the rate of one percent (1%) per year from the Effective Date of this Contract on an annual basis and year-to-year thereafter.  Once thirty-six BCF of Cedar Hills Volumes have been delivered, Buyer is not entitled to collect a fee for this service.

b.                                  CO₂ Fee:                                               When the average composite volume of CO₂ from the Cedar Hills Volumes and the MPHU Volumes is less than ten percent (10%) by volume, Buyer shall be entitled to and shall deduct a fee of ten cents ($.10) per MCF.   When the average composite volume of CO₂ from the Cedar Hills Volumes and the MPHU Volumes is equal to or greater than ten percent (10%) but less than or equal to fifteen percent (15%) by volume, Buyer shall be entitled to and shall deduct a fee of twenty cents ($.20) per MCF.  Under no circumstances shall the average composite volume of CO₂ from the Cedar Hills Volumes and the MPHU Volumes exceed fifteen percent (15%) by volume. The applicable fee shall be escalated at the rate of one percent (1%) per year from the Effective Date of this Contract on an annual basis and year-to-year thereafter.

c.                                   Fuel Fee:                                              If Seller takes more than 50% of the Residue Gas available for sale in any month, Seller agrees to pay Buyer an amount determined by multiplying i) the difference between the amount taken and 50% of the

12

Residue Gas available for sale by ii) the price received for Residue Gas sold for such month.

d.                                  Electrical Fee:  Seller agrees to pay fifty percent (50%) of the electrical costs attributable to Seller’s gas for all compression, plant and field needs, as well as other plant or facility electrical charges, based on the volume of gas measured on a monthly basis from all points of delivery from Seller.

10.6                      Any time after the fifth anniversary of the Effective Date of this agreement, Seller shall have the one time option to convert the proceeds percentages in Sections 10.3 and 10.4 hereof from fifty percent (50%) of Plant Products and Residue Gas to ten percent (10%) of Plant Products and Residue Gas.  In the event that Seller elects to exercise this one time option, the gathering fee and CO2 fee in Section 10.5 hereof shall be eliminated in their entirety.  In addition, the fuel fee and electrical fee in Section 10.5 hereof shall be reduced to ten percent (10%).   The election shall be made in writing by Seller to Buyer and shall become effective the first day of the month following said notice, provided the notice is delivered at least ten (10) days prior to the end of the month.

10.7                        Notwithstanding the foregoing provisions of this Article 10, PRICE, if at any time, and from time to time, Buyer in its sole judgment determines that, at any point or points of delivery, operating conditions relating to Buyer’s facilities or market conditions relating to Buyer’s purchase of gas or resale of the gas and natural gas liquids indicate that a downward price revision is necessary or appropriate, then Buyer may elect to notify Seller of Buyer’s intent to renegotiate Seller’s price and pricing basis or to terminate this Contract.  Any notice of renegotiation of price or termination shall be given in writing by Buyer to Seller not less than thirty (30) days prior to the date upon which such notice is to become effective.    Seller has thirty (30) days after receipt of notice of price renegotiation to accept such renegotiation or cancel the contract.  Such, if any price reduction, shall be in effect only as long as the condition that caused the reduction exists.  Any price reduction shall only remain in place so long as the condition that caused the reduction exists.
