Seller shall not deliver the Gas to any party other than Buyer, Seller shall deliver at the Delivery Point such quantities of Gas from each Well, as each such Well is capable of flowing Gas, up to the maximum flow rate of such Well, and Buyer shall purchase and receive such Gas from time to time on a best efforts basis subject to Buyer’s available capacity and the ability of Buyer to take the Gas in Buyer’s sole discretion.

2.2. Purchases. All Delivered Quantities shall serve to satisfy any and all of Buyer’s obligations arising under this Agreement. Should the Delivered Quantity of Gas purchased by Buyer for any three (3) month period of a Contract Year total less than the Contract Quantity, for any reason other than force majeure, the exercise of any reservations of Seller or Buyer, or any failure of Seller to perform its obligations under this Agreement. Seller may, as its sole and exclusive remedy, obtain a release of the Gas from the parties purchase and sale obligations hereunder, Seller shall make a request for release of the Gas by providing written notice thereof within thirty (30) days after the last day of such three (3) month period of any Contract Year. Any such release shall be effective as of the date stated in any notice from Seller but not earlier than the first day of the next following calendar month which begins at least thirty (30) days after such notice is given.

2.3. Reservations of Buyer. Buyer reserves the right to shut-in and cease taking deliveries of Gas from any Well so long as Buyer, determines that due to operations of Seller, its agents, representatives, or contractors, a dangerous and/or unsafe condition exists. Upon Buyer’s giving notice of any such shut-in or xxx and continuing until such condition is remedied to Buyer’s satisfaction, there shall be no obligation to sell or purchase Gas attributable to any such Well.

2.4. Reservations of Seller. Seller reserves the following rights under this Agreement:

2.4.1. to pool or unitize the Leases with other leases in the same field, provided that all Gas attributable to Seller’s interest in any unit so formed shall, to the extent of Seller’s interest in the Leases, be deemed subject to this Agreement;

2.4.2. to use Gas in developing and operating the Leases or any unit in which the leases are unitized or pooled and for fulfilling obligations to the lessors Under the Leases for domestic fuel;

2.4.3. to retain all liquid hydrocarbons separated from the Gas prior to the delivery to Buyer by the use of conventional mechanical gas/oil field separators of the type in use, if any, as of the date of this Agreement;

2.4.5. to cease production as to, or abandon, Wells which are not producing in paying Quantities.

3.1.1. Contract Price. Subject to Sections 3.2 and 3.5, the Contract Price per MMBtu to be paid to Seller for purchases by Buyer under this Agreement shall be the Index Price, as defined in Exhibit “B” attached hereto and made a part hereof, multiplied by ninety percent (90%), less a reduction in the Contract Price equal to thirty (30) cents for each MCF of Gas delivered (“Contract Price Reduction”). Buyer shall deduct from the Contract Price fees for compression, dehydration, and additional treating services, if any, as specified in this Agreement. The Contract Price Reduction shall be increased annually based on the percentage increase in the average weekly earnings of Crude Petroleum and Gas Production Workers for the last calendar year compared to the calendar year preceding as shown by the index of average weekly earnings of Crude Petroleum and Gas Fields Production Workers as published by the United States Department of Labor, Bureau of Labor Statistics.

3.2. If the Gas requires processing to remove hydrocarbon liquids prior to being sold, and the value of those hydrocarbon liquids sold at the plant attributable to Seller’s Gas are less than the value of the equivalent MMBtu’s of the hydrocarbon liquids removed from Seller’s Gas times the Index Price “Shrink Value”, then Buyer shall deduct from the Contract Price the difference between the Shrink Value and the value of the hydrocarbon liquids sold at the plant attributable to Seller’s Gas, in addition to any other price reductions contained herein.

3.3. Index Failure. “Index Failure” means the Contract Price for Gas purchased hereunder is calculated based on the Index Price but one or more of the following occurs:

3.3.1. the “Index Price”, as defined in Exhibit “B” cannot be calculated for any reason.

3.3.2. Inside FERC or NGI change the method it uses to calculate any Index or contract price listed in Exhibit “B” and such price as a result of such change does not reflect the monthly spot price for such gas for the Designated Regions or Pipelines.

If Index Failure occurs for any one (1) month period during any Contract Year, then the Contract Price for such month and all succeeding months until a new Contract Price has been

determined pursuant to this Section 3.2 shall be the Contract Price in effect for the preceding month, less any reductions thereof as provided herein. Subsequent to the Index Failure and for a period of sixty (60) days thereafter, the parties will use reasonable efforts to jointly determine a new index or indexes to be used to define an Index Price which most closely resembles the current market therefore. If the parties agree upon a new index or indexes to be used to define an Index Price pursuant to this Section 3.2, the Contract Price for the month in which the Index Failure occurred and all subsequent months will be calculated based upon such Index Price and the Contract Price and all payments previously made with respect thereto shall be adjusted accordingly. On the next succeeding Statement Day (as defined in Section 3.3 below), Buyer shall include in such statement xxx adjustments to each prior month’s Contract Price to be adjusted and the amount due to or from Seller. If amounts are owed to Buyer, Buyer will be entitled to a credit for amounts due pursuant to such statement, otherwise the amount due to Seller will be increased by the amount of such adjustment. If the parties have not agreed on and made effective a new Index Price and, thus, Contract Price, within the above–referenced sixty (60) day period, then the index Price and, thus, Contract Price shall be determined by arbitration which most closely reflects the current market therefor. If a new Contract Price is agreed to under this Section 3.2, such Contract Price shall continue in effect until a new Contract Price becomes effective.

3.4. Statements. On or before the twenty-fifty (25th) day (“Statement Day”) of each calendar month, Buyer shall give a statement to Seller showing (a) the quantity of Gas purchased during the last preceding calendar month hereunder and (b) the Contract Price for that Gas, including any reductions thereof as provided herein. On or before the fifth (5th) day of the calendar month next following the month in which such statement is given, payment shall be made in accordance with the statement. Regardless of any mistake by the parties or any subsequent change in applicable law, any claim by either party of error as to any statement shall be waived unless written notice of the claim is given to the other party within two (2) years next following the Statement Day for that statement.

3.5. Seller to Pay Taxes. Seller shall pay and discharge all severance, production or similar taxes or governmental charges assessed against or on the basis of the Gas before title to the Gas passes to Buyer. The Contract Price paid by Buyer will be the total consideration paid by Buyer to Seller and is inclusive of any and all costs, xxx, and taxes (including 100% of all gross production, severance or other taxes now or hereafter required by law to be paid to any applicable governmental authority with respect to the production of Gas delivered hereunder). Buyer shall be entitled to withhold from payments to Seller under this Agreement and disburse to governmental authorities any amounts for taxes or similar changes as Buyer may, from time-to-time, determine to be required by applicable law.

3.6. Maximum Lawful Price. In the event any Contract Price to be paid hereunder exceeds any maximum price permitted by applicable law, the Contract Price shall be reduced to said maximum lawful price.

4.1. Initial Wells. Buyer shall proceed with due diligence to install, at its expense, all facilities at and downstream of the Delivery Point which are necessary to receive Gas from Seller. All such Delivery Point and downstream facilities will be owned and operated by Buyer at its expense. Seller shall proceed with due diligence to install, at its expense, all facilities upstream

of the Delivery Point which are necessary to connect any Gas to Buyer’s system. All such upstream facilities will be owned and operated by Seller at its expense.

4.2 Subsequent Wells. With regard to any Well (“Subsequent Well”) which is completed for production subsequent to the date of this Agreement, Seller shall, within thirty (30) days from the date of completion of such Subsequent Well, provide Buyer any and all relevant Well data (including, but not limited to daily drilling reports, logs, completion reports, flow test, and gas analysis) (“Well Data”). Seller shall have the right, but not the obligation, to connect such Subsequent Well to Seller or Buyer’s system at its expense. If Seller elects not to construct such facilities, or does not initiate construction of such facilities within thirty (30) days after the Well Data is received by Buyer. Buyer may construct, at its expense, the facilities necessary to deliver the Gas from such Subsequent Well to Buyer’s xxx system. If neither party connects any Subsequent Well, Seller shall be entitled to a xxx release from this Agreement as to that Subsequent Well only. The obligation to connect Subsequent Wells shall only apply to all Wells completed in the xxx formation and Wells with similar characteristics or of better quality than gas produced from such formation.

4.3. Maintenance of Facilities. Buyer agrees to maintain its facilities for the Delivery Point at least for so long as the actual deliveries of Gas measured from such Delivery Point are at least one hundred (100) xxx per day (“Minimum Production”) averaged over any calendar month. If the actual deliveries measured for such Delivery Point should total less than the Minimum Production and it is not profitable because actual costs (excluding overhead and depreciation ) exceed revenues. Buyer shall have the option to disconnect and remove its facilities from the Delivery Point and release each Well & leases upstream of such Delivery Point, as to the then producing interval, from this Agreement.

5.1. Title; Liability. Title to all Gas purchased by Buyer shall pass from Seller to Buyer upon delivery at the Delivery Point. The party having possession and control of the Gas at any time shall be responsible for any related damage or injury, except any damage or injury caused by the other party’s negligence or intentional wrongdoing.

5.2. Delivery Pressure. Seller shall deliver the Gas to Buyer at pressures sufficient to permit accurate measurement of the Gas and to enter Buyer’s system at the Delivery Point against the pressures prevailing in such system, from time-to-time, up to and including the Maximum Delivery Pressure. Seller shall not deliver the Gas at the Delivery Point at pressures in excess of Buyer’s maximum allowable operating pressure (“MAOP”), as Buyer may, from time-to-time, determine and notify Seller. Seller at its expense shall install and maintain fail safe overpressure protection equipment which Seller shall, within ten (10) days after Buyer notifies Seller of Buyer’s MAOP or any change in MAOP, set at a pressure not to exceed the MAOP stated in that notice. Seller’s over pressure protection equipment shall be of standard manufacture and shall be tested not less often than once per year by reasonable means and methods by Seller upon at least three (3) days advance written notice to Buyer. Buyer shall have the right to observe the test. Seller shall promptly notify Buyer of the results of the test and provide Buyer with a copy of any written test report prepared by or for Seller.

5.3. Maximum Delivery Pressure. Seller shall not be required to deliver Gas to Buyer at the Delivery Point at pressures exceeding the Maximum Delivery Pressure. In the event the Maximum Delivery Pressure at the Delivery Point is exceeded for a period of at least sixty (60) consecutive days, Seller may notify Buyer in writing of the occurrence. Buyer shall have thirty (30) days after such notice is received to reduce the pressure at the Delivery Point to a pressure less than or equal to the Maximum Delivery Pressure. If Buyer has not reduced the pressure at the Delivery Point to a pressure less than or equal to the Maximum Delivery Pressure within said thirty (30) day period, Seller shall be entitled upon written notice to Buyer, as its sole and exclusive remedy, to a release from this Agreement for each Well upstream of that Delivery Point, as to any and all intervals which are then completed for production.

5.4. Delivery of Pipeline Quality Gas. Seller shall deliver only Pipeline Quality Gas to Buyer. If Seller’s Gas produced from the Wells dedicated to this Agreement fails to meet any of the specifications for Pipeline Quality Gas, then Buyer shall at it’s option:

5.4.2. accept all or any part of the tendered Gas, and charge a reasonable fee to treat the Gas which fails to meet any of the specifications for Pipeline Quality Gas.

6.1. Heating Value. For all purposes (including without xxx pricing and payment) under, this Agreement the heating value of and the number of xxx contained in Gas shall mean, and be measured in terms of the gross number of xxx that would be contained in the volume of such Gas (measured in accordance with this Article) when xxx with water and at Standard Base Conditions. The xxx contained in hydrogen sulfide or other non-hydrocarbon components will be excluded in any calculation of the number of xxx contained in Gas under this Agreement.

6.2. Standard Unit of Volume. For all purposes under this Agreement, volume shall mean, and be measured in terms of cubic feet of Gas at Standard Base Conditions. The temperature recorded during each day, the factor as determined in the latest feet for specific gravity, and the correction for deviations from Boyle’s Law as determined in the latest test shall be used to make proper computations of volume under this Agreement.

6.3. Measuring and Testing Equipment and Procedures. Buyer shall at its expense perform or cause to be performed all measurement and testing of Gas under this Agreement, including measurement at the Delivery Point:

6.3.1. of volumes by continuous use of an office xxx and computations made in accordance with the latest version accepted by Buyer of the Gas Measurement Committee Report No. 3 of the American Gas Association (“AGA”);

6.3.2. of Gas heating value by periodic testing of Gas samples by calorimeter, chromatography or other means commonly used in the gas industry;

6.3.3. of specific gravity to the nearest one thousandth (1/1000) by periodic testing;

6.3.6. of carbon dioxide, hydrogen sulfide and water content of the Gas by periodic tests using apparatus and methods approved by the AGA, the Gas Processing Association and the American Petroleum Institute or agreed upon by the parties. Measuring and testing equipment of standard manufacture shall be provided, maintained and periodically tested by reasonable means and methods at Buyer’s expense; and

For all measurement and tests, the average atmospheric (barometric) pressure shall be assumed to be the Assumed Atmospheric Pressure for Measurement and Tests. All charts shall be integrated within the accuracy prescribed by the manufacturer of the equipment producing the chart. The results of each periodic test shall, subject to the provisions of Section 6.4. be effective and used for all purposes under this Agreement from the first day of the month during which the test is conducted until the first day of the month during which the next similar test is conducted. All periodic tests of Gas samples and measuring and testing equipment shall be conducted at reasonable intervals, at times determined by Buyer, Seller shall have the right to observe all such tests, and upon written request from Seller. Buyer shall give to the operator at least three (3) days advance notice of the time and nature of each test. If after such notice, Seller fails to have a representative present, the test shall proceed and its results be used until the next similar test.

Seller may install and operate check-measuring equipment that does not interfere with Buyer’s measurement and testing. Buyer and Seller shall each have the right to inspect the equipment of the other, and the charts and other measurement and testing xxx of the other, at all times during business hours, but the reading, xxx and adjustment of any equipment and changing of charts shall be done only by the party owning the equipment. Each party shall preserve all original test xxx, charts and other similar records in the party’ s possession for a period of at least two (2) years.

6.4. Correction of Inaccuracies. If at any time any measuring or testing equipment is found to be malfunctioning, it shall be adjusted at once to read accurately, within the limits prescribed by the manufacturer. If such malfunction is reasonably estimated to have resulted in inaccuracy exceeding two percent (2%) in the measurement of Gas at a Delivery Point during the period since the last preceding test, the parties shall estimate the quantity of Gas actually delivered at the Delivery Point during that period using the xxx recorded by check-measuring equipment, if installed and accurately xxx during the period, of, if such check-measurement xxx is not available by connecting the original measurement error by the percentage error found in the measuring and testing equipment or, if such check-measuring data is unavailable and correction for percentage error is not feasible, by estimating deliveries based upon deliveries under similar conditions during a period when the measuring and testing equipment was functioning properly. If the period of actual equipment malfunction is not definitely known or agreed upon by the parties, it shall be deemed to be the lesser of (a) forty-five (45) days or (b) one half of the xxx time since the last preceding test. Such estimate shall then be deemed the quantity of Gas actually delivered for all purposes under this Agreement. No corrections shall be made for measurement or testing inaccuracies of two percent (2%) or tests.

Seller represents and warrants to Buyer the following as of the effective date of this Agreement and at all subsequent times during the term of this Agreement, and Seller agrees that such representations and warranties shall survive the termination of this Agreement.

7.1. xxx. Buyer’s receipt of Gas under this Agreement will not subject Buyer, its facilities or the Gas to regulation under the Natural Gas Act.
