Such determinations shall be made as often as Company deems necessary and Supplier may witness such determinations or make joint determinations with its own appliances. If in Supplier’s judgment the result of any such test or determination is inaccurate, Company, at Supplier’s request, will again conduct the questioned test or determination, and the costs of such additional test or determination shall be borne by Supplier unless same shows the original test or determination to be materially inaccurate.

Failure to Meet Specifications: Should any of Supplier’s Gas delivered by Supplier hereunder at a given Delivery Point fail to meet any of the Specifications, Company may at its option accept, or immediately discontinue or curtail receipt of Supplier’s Gas at such Delivery Point until such time as Supplier’s Gas meets the required Specification(s). Company may elect to take Supplier’s Gas not meeting the Specification(s); however, Company’s election to do so shall not constitute a waiver of the Specification(s) as to any other Supplier’s Gas.

Should Supplier’s operations or any of Supplier’s Gas create a condition which in the judgment of Company tends to endanger the Plant or other property of Company or the lives or property of Company’s employees or any Third Party, Company may discontinue receipt of Supplier’s Gas so long as such condition exists.

Company shall notify Supplier of such failure of Supplier’s Gas to meet the Specification(s) and Supplier shall make diligent effort to deliver such Gas conforming to the Specification(s). If Supplier fails and/or refuses to deliver Gas conforming to the Specifications, within a reasonable time following Supplier’s receipt of Company’s notice, Company shall have the right to terminate this Agreement as to the leases and/or ▇▇▇▇▇ producing Supplier’s Gas which fails to meet the Specification(s) without any liability whatsoever to Supplier.

Fee: If Company accepts delivery of Supplier’s Gas which does not meet the Specifications, Company may either: i) charge Supplier an agreed treating fee, if agreed to by Supplier’s representative, for the purpose of recovering costs incurred by Company to monitor Supplier’s Gas quality and/or to bring Supplier’s Gas within the Specification(s); or ii) if Supplier has not agreed to a treating fee, may recover, and be fully reimbursed by Supplier for all actual and reasonable costs incurred by Company to monitor Supplier’s Gas quality and/or to bring Supplier’s Gas within the Specification(s). Supplier agrees that agreement of Supplier’s representative to a negotiated treating fee, as provided for above, may be evidenced by electronic messages and Company may rely on such method of confirmation of agreement to such fee. In addition, Supplier agrees to indemnify, defend and hold Company harmless from and against any and all Claims arising out of, relating to or in any way connected with, the delivery of Supplier’s Gas to Company which does not meet the Specifications.

A.6. Payments to Supplier

Payment of amounts owed hereunder by Company to Supplier shall be made not later than the last Business Day of each Month for all Supplier’s Gas delivered to Company during the preceding Month. Supplier shall be furnished a separate statement showing full details of Supplier’s account. If during any Month the amount payable hereunder shall be less than one hundred dollars ($100.00), or such lower amount as may be required by applicable law, Company may withhold payment without penalty or interest until such time as the amount payable to Supplier equals or exceeds such amount, in which event, payment shall be made on the next regular Monthly payment date. Within thirty (30) Days after expiration or termination of this Agreement, Company shall pay Supplier all amounts which are due and owing under this Agreement.

Examination by the Supplier of the accounting records maintained by Company respecting Supplier’s Gas shall be permitted by Company during normal business hours upon reasonable written request delivered to Company within twenty-four (24) Months from the end of the Month in which such statement or invoice was issued (“Transaction Month”). If any such examination reveals any inaccuracy in any statement, charge or invoice which is agreed to by the Parties, the necessary adjustment shall be made promptly. Supplier shall submit a written explanation of any adjustments or other claims it wishes to assert as a result of its examination and the Parties shall endeavor to resolve any disputes regarding such claims or adjustments within thirty (30) Months after the end of the Transaction Month. The correctness of all such statements and/or invoices shall be presumptively established and shall preclude the making of claims for adjustment thereon by either Party in any manner whatsoever, whether by filing an action in a court of law or otherwise, upon the expiration of thirty-six (36) Months from and after the end of the Transaction Month, unless such an action in a court of law is filed prior to such expiration. The making of a written claim for adjustment by either Party against the other within the above required 36 Month period shall operate to suspend the running of the applicable statute of limitations for such claim only until the end of such 36 Month period.

Notwithstanding any change in ownership of Supplier’s Interest, Company shall never be required to make payments or to give notices required under the provisions of this Agreement to more than one party, and, in the event Supplier’s Interest shall ever be owned by more than one party, Company may withhold (without interest) further payments and notices until all of the owners thereof have designated one party to act for them in all respects relating to Supplier’s Interest and this Agreement, including the rendering of bills, the submission of charts, and the receipt of payments and notices hereunder.

Company shall mail statements or invoices, as applicable, pertaining to Supplier’s Gas delivered hereunder by the last Day of each Month for the preceding calendar Month. Supplier shall pay each invoice rendered hereunder within fifteen (15) Days of Supplier’s receipt of the invoice. Company shall have the option to deduct the Fees and any other amounts owed by Supplier to Company hereunder from any payments otherwise due Supplier from Company hereunder, provided that should Company elect to make such deductions Company shall include all amounts owed to and from Supplier hereunder for the applicable period to determine the net amount owed by the Party that is the net payor under for that period.

A.8. Royalties and Other Payments

Supplier hereby assumes sole responsibility for accounting to and paying the lessors, working interest owners, royalty owners and all other Persons legally entitled thereto (the “Interest Owners”) all royalties, overriding royalties, bonus payments, production payments and other payments due on Supplier’s Gas and the Plant Products, Drip Liquids and sulfur extracted therefrom (or the Proceeds attributable thereto) and Supplier agrees to and does hereby indemnify, defend and hold Company and its Affiliates (including its Affiliates’ directors, officers, employees, agents or representatives) harmless from and against any and all Claims arising out of, relating to or in any way connected with, the payments provided for in this Section A.8 and/or Supplier’s failure to make such payments.

A.9. Taxes

Supplier agrees to bear and to pay or cause to be paid all excise, severance, production, sales, and other taxes applicable to Supplier’s Gas delivered to Company hereunder. In addition, Supplier agrees to bear all taxes assessed on Supplier’s settlement share of the Plant Products and Residue Gas extracted from Supplier’s Gas (or the Proceeds attributable thereto, as the case may be) and any fuel use or Processing taxes which may be assessed against Company in respect of Supplier’s Gas. If for any reason Company is required to disburse any such taxes, Company shall deduct the amounts so paid from any amounts paid to Supplier hereunder or shall invoice Supplier for same if no such payments are made by Company or if the payments made are insufficient to cover such taxes and/or assessments. Each Party agrees to make all tax reports, which it is obligated to make to the applicable taxing authorities.

Neither Party hereto 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 Agreement. Each Party shall pay any and all ad valorem, employment, occupation, income and other taxes of like nature levied, assessed or collected on or with respect to that Party’s property, operations or income derived hereunder or shall furnish to the other Party all tax exemption certificates exempting such Party from the obligation to pay any such taxes.

A.10. Delivery Pressure

Supplier shall make delivery of Gas hereunder to Company at a pressure sufficient to enable Supplier’s Gas to enter the Gathering System against the pressure maintained therein from time to time, it being understood that such operating pressures may fluctuate substantially over the term of this Agreement.

A.11. Reservations by Supplier

Supplier hereby expressly reserves the following rights with respect to Supplier’s Gas:

•		the right to use Supplier’s Gas prior to delivery to Company for (1) developing and operating the Dedicated ▇▇▇▇▇ and/or the ▇▇▇▇▇ situated on the Dedicated Acreage and (2) to fulfill obligations to Supplier’s lessors or royalty interest owners therein, including Gas delivered pursuant to the exercise of any take-in-kind rights which such lessors and/or royalty owners may have and/or Gas delivered pursuant to good faith settlement agreements with lessors concerning take-in-kind right claims or demands;
•		the right to pool, combine, unitize or communitize the Dedicated Acreage (or any portion thereof) committed hereto with other lands and leases so long as such action does not reduce Supplier’s Gas reserves and, in the event of any such pooling, combination, unitization or communitization, this Agreement will cover Supplier’s Interest in the pool or unit formed and the Gas attributable thereto; and,
•		the right to operate Supplier’s properties free from any control by Company and in such manner as Supplier, in its sole discretion, may deem advisable, including, without limitation, the right, but not the obligation, to drill new ▇▇▇▇▇, to repair and rework old ▇▇▇▇▇, or to renew or extend, in whole or in part, any Lease dedicated hereunder or to abandon any well or surrender any land or lease, in whole or in part, when no longer deemed by Supplier to be capable of producing Gas in paying quantities.

A.12. Production in Conformance with Flow Schedule

In order to maintain maximum Plant efficiency on a (twenty-four) 24-hour operating schedule, it is desired by the Parties hereto to maintain a reasonably uniform rate of flow of Gas to said Plant over each (twenty-four) 24-hour period. Accordingly, Supplier shall, as reasonably practical, regulate its producing schedule so that Supplier’s Gas shall be supplied from Supplier’s well or ▇▇▇▇▇ at a reasonably uniform rate of flow or accept and follow a producing schedule to be established by Company from time to time. Company shall take into consideration the wishes of Supplier in establishing the producing schedule for Supplier’s well or ▇▇▇▇▇. Anything else contained in this Agreement to the contrary notwithstanding, Supplier hereby agrees that in the event it fails to comply with the above provisions of this Article, such failure shall give Company the right, at its option, to refuse to accept delivery of Supplier’s Gas during any period of such non-compliance. Should Supplier produce and deliver Gas by intermitted or by stopcock production methods, Company shall have the option to change the measuring facility to insure a constant recording pattern for the delivery of Supplier’s Gas. These methods may include installation of pressure restricting devices upstream of the facilities owned by Company or Company’s designee. All costs associated with this conversion shall be borne by Supplier or Supplier shall provide Company or Company’s designee with the appropriate equipment for such facilities. If Supplier elects to furnish the equipment, the operation of said equipment shall remain the responsibility of Company or Company’s designee.

Exhibit A — General Terms and Conditions		Page 5
DYNEGY CONTRACT NO.: 014904 — Ref No. 095

A.13. Flush Gas and Curtailment Conditions

A “Flush Gas Condition” exists whenever the Gathering System, if any, utilized to deliver Gas to the Plant and/or the Plant is of insufficient capacity to gather and/or Process all of the Gas connected thereto. During any period when a Flush Gas Condition exists, Company shall take Supplier’s Gas ratably as to quantity with all other Gas of the same quality connected to the Plant, but shall not be obligated to take any quantities of Gas in excess of such prorated volumes.

During any periods of curtailment by Residue Gas and/or Products purchasers or transporters (a “Curtailment Condition”), Company shall only be obligated to take Supplier’s Gas to the extent that such Residue Gas and/or Product purchasers or transporters are taking Residue Gas and/or Products.

Notwithstanding anything in this Agreement to the contrary, Company shall not be obligated to expand the capacity of the Gathering System or Plant to accommodate Supplier’s Gas. Supplier shall have the right to dispose of the excess Gas not taken by Company on a temporary basis during any Flush Gas or Curtailment Condition, subject to Company’s right to take such Gas at any subsequent time upon giving Supplier at least ten (10) Days’ written notice of its election to do so.

A.14. Settlement Tests

In accordance with the testing schedule as set forth in the section entitled “Testing Schedule” of the Commercial Terms and Conditions, Company shall obtain a representative sample of Supplier’s Gas at each Delivery Point and determine the composition in mole percent, theoretical Product content in GPM, Gross Heating Value in Btu per cubic foot on a water saturated basis, gasoline content (iC₅+), if required, specific gravity and hydrogen sulfide by means of Gas chromatography according to the latest edition of Gas Processors Association (GPA) Standard 2261, “Analysis of Natural Gas and Similar Gaseous Mixtures by Gas Chromatography” or other generally accepted methods in the industry. The Gas samples shall be taken at the actual flowing conditions, in accordance with the latest edition of GPA Standard 2166, “Obtaining Natural Gas Samples for Analysis by Gas Chromatography.” The Gross Heating Values for various hydrocarbon components shall be determined from the latest edition of GPA Standard 2145, “Table of Physical Constants of Paraffin Hydrocarbons and other Components of Natural Gas.” The specific gravity may be determined by the use of a gravitometer of the Ranarex type. The hydrogen sulfide content shall be determined according to the latest edition of GPA Standard 2377 entitled “Test for Hydrogen Sulfide and Carbon Dioxide in Natural Gas Using Length of Stain Tubes” or by Gas chromatography according to the latest edition of GPA Standard 2261. The calculations of Product GPMs determined from such analysis shall be made by utilizing applicable conversion factors (corrected to the measurement conditions herein stated) as contained in the latest edition of GPA Standard 2261. These methods may be replaced, at Company’s discretion, by any method commonly used in the industry. All analysis results shall be utilized for settlement purposes beginning with the Month following the Month in which the results were obtained, and shall be effective until the next scheduled test. The settlements tests shall be made by Company in accordance with the Testing Schedule except when, in the opinion of either Party, a change in the method of operations of the lease will affect materially Supplier’s Gas composition, Gross Heating Value, specific gravity and/or hydrogen sulfide content, in which event, the tests shall be made at the demand of either Party upon ten (10) Days’ notice to the other Party. If the Supplier makes such demand, the reasonable cost for such settlement test shall be reimbursed by Supplier to Company. Company shall notify Supplier in writing at least ten (10) Days’ prior to any settlement tests conducted hereunder in order that Supplier may have a representative present to witness such tests and/or make joint tests with its own appliances. If the Gas composition, Gross Heating Value, specific gravity and/or hydrogen sulfide content as revealed by any analysis made in accordance with the Testing Schedule is substantially the same as determined in the previous analysis, or if the volume of Gas delivered hereunder is less than fifty thousand cubic feet per Day (50 Mcf per Day), then Company, in its sole discretion, shall have the right to reduce the frequency of settlement tests. Notwithstanding the testing schedule set forth in the section entitled “Testing Schedule” of the Commercial Terms and Conditions, if a well subject to this Agreement produces less than a Monthly average rate of (a) one hundred thousand cubic feet (100 Mcf) per Day, if the GPM content of the Gas delivered from such well is 2 GPM or less or (b) twenty thousand cubic feet (20 Mcf) per Day, if the GPM content is 2 GPM or more, Company, in its sole discretion, shall have the right to suspend all or a portion of such tests until the well produces at the rates as set forth in (a) and (b) above, as applicable for at least t wo consecutive Months. If Company suspends any such testing, the most recent test that was made shall be utilized for settlement purposes unless Company subsequently elects to test such well, in which event, such test shall thereafter be used for settlement purposes.

A.15. Meters and Measurement

Supplier’s Gas delivered hereunder shall be measured by a suitable orifice meter, or meters, or other generally accepted measuring devices, of standard make near the Delivery Point. Such metering equipment shall be installed, operated and the volumes calculated in accordance with the prescribed recommendations of American Petroleum Institute Manual of Petroleum Measurement Standards (“API MPMS”), Chapter 14, Natural Gas Fluids Measurement, Section 3, Concentric, Square-Edged Orifice Meters, Parts 1, 2, 3 & 4, 1991 Edition or latest revision. Revisions to such Edition shall apply to computations and operation of meter installations but shall not be construed to require modifications to, or replacement of, said equipment. The computation of all Gas volumes measured by orifice meter shall also be made in accordance with API Chapter 20, as amended from time to time; provided, however, that all factors involved in the computation of Gas volumes measured hereunder shall be subject to and in accordance with applicable state laws. Company may, at its option, install an electronic flow recorder to record the static and differential pressures, flowing temperature and volume of such Gas. In the event the Gas is measured by positive displacement meters, such meters shall be installed, maintained and operated in accordance with AGA Report No. 7, 1985 edition (for turbine meters) or ANSI/ASC B109.3-1992 edition (for rotary meters), as such publications may be supplemented and amended from time to time. All of Supplier’s Gas volumes measured hereunder shall be computed to a standard pressure base of (1) 15.025 pounds per square inch absolute, if the Gas is produced from properties situated in or off the coast of Louisiana; and (2) 14.65 pounds per square inch absolute, if produced from properties situated in or off the coast of any other State, at a standard base temperature of sixty (60) degrees Fahrenheit.

Company shall periodically, but no less frequently than the schedule agreed to for Settlement Tests which are performed as provided in the section entitled “Settlement Tests”, test the accuracy of the measuring equipment operated by it hereunder using means and methods generally accepted in the Gas industry. If, at any time, the Gas 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

Exhibit A — General Terms and Conditions		Page 6
DYNEGY CONTRACT NO.: 014904 — Ref No. 095

prescribed by the manufacturer. In case any question arises as to the accuracy of the meter measurement, said meter or meters shall be tested upon the demand of either Party. The expense of such tests shall be borne by the Party demanding such test if the meter is found to be correct and by Company if found to be incorrect. Such equipment will be judged incorrect if inaccurate by an amount exceeding two percent (2%) at a reading corresponding to the average rate of flow for the period since the last test. If such equipment is out of service or incorrect, then any previous readings of such equipment shall be corrected to zero error for any period which is known definitely or agreed upon; but in case the period is not known definitely or agreed upon, such correction shall be for a period equal to one-half (¹/2) of the time elapsed since the last test, which shall not exceed one hundred eighty (180) Days. No correction will be made for prior periods for recorded inaccuracies of two percent (2%) or less. The volumes delivered during the period such measuring equipment is out of service or incorrect shall be estimated by the Parties on the basis of the best data available using the most feasible of the following methods:

•

By using the registration of any check measuring equipment installed and accurately registering;

•

By correcting the error if the percentage of error is ascertainable by calibration, test or mathematical calculations;

•

By estimating the quantity of Gas delivered through the meter based on the quantity delivered through the same meter during the preceding period under similar conditions when the meter was registering accurately; or

•

Using other mutually agreeable methods.

Each Party shall preserve all charts, volumetric data, meter test data and applicable Gas analyses for at least two years, unless a longer time period is prescribed by applicable regulations, including any charts or test data covering any check meters that are installed. Should such data be the property of Company’s designee, Company and Supplier shall be subject to the retention practices (and availability of such data) of Company’s designee. At any time within such period, upon reasonable advance written request by either Party, records and/or charts from the measuring equipment, together with calculations therefrom, will be submitted for such requesting Party’s inspection and verification at the offices of the Party maintaining such records during normal business hours.

Supplier or Supplier’s designee shall have the right to install, maintain, and operate such check measurement equipment as it may desire as long as such equipment does not interfere with or impede in any way the operation of Company’s measurement or other equipment hereunder, and all calibrating and adjusting of check meters and changing of charts shall be done by Supplier or its designees and at its sole cost, risk and expense. Notice of the time and nature of each test shall be given by Supplier to Company sufficiently in advance to allow Company the opportunity to have a representative present during such tests, if Company so desires.

If Supplier elects to install compression near the measuring facilities installed by Company or Company’s designee, it shall be the responsibility of Supplier to reduce or eliminate any sources of pulsation in such metering facilities. This may include installation of pulsation plates, acoustic filters, pulsation bottles or other types of pulsation dampening equipment prior to delivery of Gas into the metering facilities.

A.16. Right Of Way

Insofar as Supplier has the right to do so, Supplier hereby grants to Company an easement across the properties covered hereby to lay and maintain lines and install, maintain and operate any equipment necessary to its operations and Company shall have the right of free entry for any purposes incidental to Company’s operations so long as such operations do not materially interfere with Supplier’s oil and Gas operations or the rights of the owners of such properties. Supplier warrants to Company peaceable access of ingress and egress across such properties at all times for the performance of Company’s operations. All lines of pipe and other equipment placed by Company on said properties shall remain the property of Company, and, subject to the terms of this Agreement, may be removed by Company at any time.

A.17. Indemnities

Each of the Parties hereto shall indemnify and hold the other harmless from and against any Claims arising out of the operations conducted hereunder by such indemnifying Party to the extent resulting from the negligence or willful misconduct of such indemnifying Party, its agents or its employees.

A.18. Reserve Information

From time to time hereafter, Company may request information from Supplier regarding Supplier’s geological and reserve information pertaining to the Dedicated ▇▇▇▇▇ and any ▇▇▇▇▇ situated on the Dedicated Acreage or on lands pooled, unitized or communitized therewith. Such information may be required by Company to evaluate the amount of Gas that Supplier is capable of delivering in connection with modifications to Company’s Processing facilities and for other business purposes. Supplier will, in a timely manner provide such information as requested by Company, including reasonable access to Supplier’s employed or contracted geological and engineering personnel. With respect to any information supplied to Company, Supplier makes no warranties, express or implied, as to the accuracy or reliability of such information. Company agrees to maintain the confidentiality of the information supplied to Company by or on behalf of Supplier as provided herein.

A.19. Uneconomic Gas

If, in Company’s sole judgment, the Gas available at any Delivery Point provided for hereunder is or becomes uneconomic for Company to gather and/or Process due to insufficient volume, Plant Product content, price, quality, changes in governmental regulations, or for any other reason, either i) Company shall not be required to take such Gas so long as such condition exists, or ii) Company shall have the option, exercisable in its sole discretion, to terminate this Agreement as to any or all ▇▇▇▇▇ or any then–producing formations comprising such well(s) delivering Supplier’s Gas to such a Delivery Point. If Company fails to accept or take Gas from Supplier due to Delivery Point economics for a period of sixty (60) consecutive Days, then Supplier shall have the right to have the affected well(s) released from this Agreement, as to the then producing formations only, at any time thereafter upon at least thirty (30) Days’ prior written notice; in which event, such well(s) shall be released from this Agreement at the end of said thirty (30) Day period unless on or before the last Day thereof Company resumes taking or accepting Gas from such affected well(s).

Exhibit A — General Terms and Conditions		Page 7
DYNEGY CONTRACT NO.: 014904 — Ref No. 095

A.20. Unacceptable Plant Economics

If at any time the operation of the Plant, Gathering System and/or other related equipment is rendered uneconomic, in Company’s sole judgment, due to the volume and/or Product content of all Gas committed and being delivered to Company for Processing in the Plant or due to any other cause, Company shall have the option to either: i) not take all or any portion of Supplier’s Gas so long as such condition exists or ii) to terminate this Agreement upon thirty (30) Days’ prior written notice to Supplier. If Company fails to accept or take some or all of Supplier’s Gas due to unacceptable Plant and/or Gathering System economics for a period of sixty (60) consecutive Days, then Supplier shall have the right to have the affected well(s) or volumes not taken released from this Agreement at any time thereafter upon at least thirty (30) Days prior written notice, in which event, such well(s) or volumes not taken, as applicable, shall be released from this Agreement at the end of said thirty (30) Day period unless on or before the last Day thereof Company resumes taking or accepting Gas from such affected well(s) or resumes taking the affected volumes, as applicable.

A.21. Termination

Upon termination of this Agreement (either in its entirety or as to any specific lease or well), this Agreement shall cease to have any force or effect except as to unsatisfied obligations or liabilities of either Party attributable to the period prior to the Day immediately succeeding the Day of termination, or arising thereafter as a result of such termination.

A.22. Post Termination Deliveries

In the event this Agreement terminates or is otherwise cancelled or terminated, and Company for any reason continues to accept deliveries of Supplier’s Gas, in the absence of another agreement in writing such transactions will be on a Day to Day basis under the same terms and provisions as otherwise set forth in this Agreement, except that Company may, at its option and in lieu of the original values set forth in Sections 2 and 3 of the Commercial Terms and Conditions, elect to pay and charge alternative compensation as follows:

		•		Supplier’s Plant Products Percentage:		(**) Percent (**)%
		•		Supplier’s Residue Gas Percentage:		(**) Percent (**)%
		•		Low Pressure Gathering Fee:		(**) Per MMBtu

Any of the above elections by Company may be exercised as to any or all of the Delivery Points hereunder and Company may modify its election of the above alternative compensation effective on the beginning of any Month upon ten (10) or more Days written notice.

Neither Company’s continuing to accept delivery of Supplier’s Gas on a Day to Day basis nor Company’s election of alternative compensation for any post-termination or post-cancellation deliveries shall be construed to be, and shall not operate as, an agreement by Company to extend or renew this Agreement on such terms or on any other terms, and Company may simultaneously pursue whatever administrative or other legal proceedings may be required to allow Company to cease taking deliveries of Gas hereunder.

No written communications by Supplier contrary to the provisions of this Section A.22 shall be enforceable; including (without limitation) any written offers or counter-offers purporting to create an obligation on Company to accept the terms thereof, or implying an acceptance of same by Company, should Company continue to accept delivery of Supplier’s Gas after a given date or given period of time thereafter.

A.23. Scope

In the event this Agreement covers more than one lease or well, this Agreement shall be construed as a separate agreement covering each lease or well, as applicable.

A.24. Force Majeure

If either Party is rendered unable, wholly or in part, by reason of an event of force majeure (as defined in this Section A.24 below) to carry out its obligations under this Agreement, other than to make payments due hereunder, the obligations of the Party giving such notice, so far as and to the extent that they are affected by such force majeure event, shall be suspended during the continuance of any inability so caused, but for no longer period, and such cause shall so far as possible be remedied with all reasonable dispatch. The Party suffering force majeure shall give notice and full particulars of such force majeure in writing or by facsimile to the other Party as soon as possible after the occurrence of the cause relied on.

The term “Force Majeure” shall mean any cause or event not reasonably within the control of the Party whose performance is sought to be excused thereby; including, without limitation, acts of God, strikes, lockouts or other industrial disputes or disturbances, acts of the public enemy, wars, blockades, insurrections, riots, epidemics, landslides, lightning, earthquakes, fires, tornadoes, hurricanes, storms, and warnings for any of the foregoing which may necessitate the precautionary shut-down of ▇▇▇▇▇, Plants, pipelines, Gathering Systems, or other related facilities, floods, washouts, arrests and restraints of governments and people, civil disturbances, explosions, sabotage, breakage or accidents to equipment, machinery, Gathering Systems, Plants, facilities or lines of pipe, the making of repairs or alterations to lines of pipe, Gathering Systems, Plants or equipment, inability to secure labor or materials, freezing of ▇▇▇▇▇ or lines of pipe, partial or entire failure of ▇▇▇▇▇ or lines of pipe, partial or entire failure of gas supply, electric power shortages, necessity for compliance with any court order, or any law, statute, ordinance, regulation or order promulgated by a governmental authority having or asserting jurisdiction, inclement weather that necessitates extraordinary measures and expense to construct facilities and/or maintain operations and any other causes, whether of the kind enumerated herein or otherwise, not reasonably within the control of the Party claiming suspension and which by the exercise of due diligence such Party is unable to prevent or overcome. Such term shall likewise include, in those instances where either Party hereto is required to obtain servitudes, rights-of-way, grants, permits or licenses to enable such Party to fulfill its obligations hereunder, the inability of such Party to acquire, or delays on the part of such Party in acquiring, at reasonable cost and after the exercise of reasonable diligence, such servitudes, rights-of-way, grants, permits or licenses, and in those instances where either Party hereto is required to furnish materials and supplies for the purpose of constructing or maintaining facilities or is required to secure permits or permissions from any governmental agency to enable such Party to fulfill its obligations hereunder, the inability of such Party to acquire, or delays on the part of such Party in acquiring, at reasonable cost and after the exercise of reasonable diligence, such

DYNEGY CONTRACT NO.: 014904 — Ref No. 095

EXHIBIT D – ALLOCATION METHODOLOGY

to
GAS PURCHASE AGREEMENT

Plant Products

The Plant Products attributable to the Gas delivered by Supplier hereunder during each Month shall be the quantities of Plant Products obtained by multiplying the volume of Supplier’s Gas delivered during such Month hereunder by the Recovered Plant Product GPM of such Gas for each Plant Product. The “Recovered Plant Product GPM” as used herein shall be the “Plant Product GPM” for each Plant Product, determined as provided for in the Section in the General Terms and Conditions entitled “Settlement Tests”, multiplied by the Actual Plant Product Recovery Adjustment. The “Actual Plant Product Recovery Adjustment” shall be a fraction, the numerator of which shall be the volume of each Plant Product recovered and saved at the Plant during each Month; and the denominator of which shall be the theoretical quantity of those same Plant Products contained in the total volume of Gas delivered to Company from all sources during each Month. The total theoretical quantity of each Plant Product shall be the summation of the volumes of each Plant Product attributable to all Gas received by Company from all sources at all Delivery Point(s) as determined by multiplying the volumes of such Gas each Month by the Plant Product GPM of such Gas.

Residue Gas

The Residue Gas attributable to the Gas delivered hereunder shall be allocated on a Btu basis, based on a factor, the numerator of which will be the wellhead delivered Btus of Supplier’s Gas delivered under this Agreement, reduced by subtracting (1) Supplier’s calculated Btus extracted as Plant Products and (2) Supplier’s allocated Plant Fuel and hydrogen sulfide, and the denominator of which will be the sum of all Plant wellhead delivered Btus, reduced by subtracting the calculated Btus extracted as Plant Products, actual Btus of Plant Fuel, and hydrogen sulfide, such factor to be multiplied by the total Plant Residue Gas available at the tailgate of the Plant.

Supplier may use Gas produced from the Dedicated Acreage and/or Dedicated Well(s) for the purpose of developing and operating same, including the use of Gas for Gas lifting or for pressure maintenance and/or cycling operations, but Company shall not be obligated to return Residue Gas to Supplier’s lease for use in the development and operation of the Dedicated Acreage and/or Dedicated Well(s); it being Supplier’s obligation to make arrangements to receive any such Residue Gas at the tailgate of the Plant. In the event that the amount of Residue Gas taken by Supplier for in connection with its operations on the Dedicated Acreage or on the Dedicated Well exceeds the amount of Supplier’s share of such Residue Gas for such Month, Company shall charge Supplier for such excess Residue Gas based on Company’s cost for and expenses to acquire such excess Residue Gas.

Allocation of Electrical Power

In the event Company elects to utilize electrical power in the operation of electrical powered compressors on the Gathering System (i.e., upstream of the first inlet compressor at the Plant), such electrical power costs will be recovered by Company by deducting from Supplier’s allocated Residue Gas a volume of MMBtus of such Residue Gas equivalent in value (to Company, at the Plant tailgate) to Supplier’s allocated share of such electrical power costs. Such Supplier’s share of electrical power costs shall be determined by multiplying the Supplier’s total such electrical power costs by a factor, the numerator of which will be Supplier’s wellhead delivered Btus and the denominator of which will be the sum of all Plant wellhead delivered Btus.

Changes to Methodology

Notwithstanding anything in this Agreement to the contrary, Company may at any time and from time to time change the allocation procedures utilized to allocate Supplier’s share of Products and Residue Gas provided that such changes can be shown to increase the accuracy of such allocations.

EXHIBIT E – SPECIAL PROVISIONS

to
GAS PURCHASE AGREEMENT

NEW PROVISIONS

The following new sections are added to the Agreement, and should same conflict with any other provisions in the General Terms and Conditions, the below new provisions shall prevail.

E.1. Partial Assignments & Scope of Partial Successors’ Delivery Commitment

Should the original Supplier party hereto or any of its Affiliates which are successors thereto assign or convey a portion of Supplier’s Production Interests in the Dedicated ▇▇▇▇▇ and/or Dedicated Acreage less than all or substantially all of the Dedicated ▇▇▇▇▇ and/or Dedicated Acreage then subject hereto (a “Partial Assignment”) from and after the effectiveness of such assignment, “Dedicated Acreage” shall thereafter (as to such successor Supplier only) mean only those areas which are within leases on which any Dedicated ▇▇▇▇▇ are located which Dedicated ▇▇▇▇▇ are within the scope of the conveyance to Supplier’s successor; and “Dedicated ▇▇▇▇▇” shall mean those Dedicated ▇▇▇▇▇ subject hereto in which Production Interests were so conveyed.

E.2. Credit

If, in the reasonable opinion of either Party hereunder (Party X) a material adverse change has occurred with regard to the financial condition of the other Party (Party Y) after the date of original execution hereof such that Party X has reasonable grounds for insecurity regarding the ability of Party Y to perform any material obligation under this Agreement (whether or not then due), Party X may demand Adequate Assurance of Performance from Party Y. “Adequate Assurance of Performance” shall mean sufficient security or proof of capability of Party Y’s capability to perform its obligations under this Agreement in the form of a standby irrevocable letter of credit (in and amount and for a term reasonably acceptable to Party X), a prepayment or a cash payment security deposit (to be held by Party X). No demand for Adequate Assurance of Performance may include a demand for security for amounts which are subject to a good faith dispute between the parties, but may include any undisputed amounts which appear on the same invoices or statements which include any such disputed amounts.

E.3. Right of Set-Off

Should a Party (the “defaulting Party”) be in default of making any payments when same are due to the other Party (the “non-defaulting Party”), the non-defaulting Party shall have the option to deduct any amounts owed to it by the defaulting Party from any payments otherwise due by the non-defaulting Party under this Agreement.

          Any such a Permitted Assignee, however, shall not be allowed to further assign this Addendum or any of the rights hereunder without Company’s prior written consent, which Company shall not be obligated to grant. In the event Supplier does convey or assign all or a part of Supplier’s

Special Addendum to Dynegy Contract No. 014904 — Ref. No. 095		Page 2

Interest to any Person other than as expressly provided for in this Section 1, the rights provided for in this Addendum shall terminate and be of no further force and effect as to Gas attributable to the portion of Supplier’s Interest which was so conveyed or assigned unless an assignment of same is expressly provided for in this Section 1 above.

          No assignment expressly allowed above or otherwise consented to by Company shall be effective until Company has received notice of such assignment and a copy of a writing in which assignee assumes and agrees to perform Supplier’s obligations hereunder and agrees to be fully bound by the terms of the Agreement and this Addendum, all only to the extent of the Production Interests assigned to such assignee.

3. Right to Take Plant Products and Residue Gas In-Kind

A. Plant Products

          From time to time during the term of the Agreement, Supplier may elect to take its percentage share of Plant Products in-kind at the tailgate of the Plant in lieu of payment of Proceeds attributable thereto as set forth in the Commercial Terms and Conditions (when not giving effect to any amendments set forth in this Addendum). The volume which Supplier will be entitled to receive each Month during any period when such an election is in effect shall be equal to the volume of Plant Products attributable to the Gas delivered by Supplier under the Agreement during such Month, as determined pursuant to Exhibit D to the Agreement (Allocation Methodology) (“Supplier’s Allocated Plant Products”) multiplied by the Supplier’s Plant Products Percentage. Such take-in-kind rights shall be subject to the following terms and conditions:

	(1)		Supplier’s initial election, which shall be effective November 1, 2003, is to take its percentage share of Plant Products in kind. Such initial election shall be applicable from said November 1, 2003, date and shall remain in effect until Supplier affirmatively elects to terminate such election, in the manner described below.
	(2)		Should Supplier wish to change its then current election (to receive Plant Products in–kind or the Proceeds attributable thereto, as applicable), Supplier shall give Company at least sixty (60) Days advance written notice of such change. Any change in Supplier’s election shall be effective on the first Day of the Month following the expiration of said sixty (60) Day period. Supplier’s initial election and any subsequent change in Supplier’s election shall remain in effect for a period of at least six (6) consecutive Months.
	(3)		Supplier shall be responsible for making its own arrangements for the transportation and fractionation of its share of Plant Products from and at the point of delivery into Product Pipelines at the tailgate of the Plant.
	(4)		Supplier may only elect to take-in-kind the entire volume of Supplier’s percentage share of Plant Products in the form of Raw Product and may not make such election as to individual Components within a commingled stream.
	(5)		Supplier shall receive its share of Plant Products in the form of Raw Product which meets the specifications of the Product Pipeline and Supplier shall not, by virtue of the Agreement or this Addendum, be entitled to fractionation services for such Raw Product to be delivered to Supplier pursuant to this Section 3.A.
	(6)		Subject to Supplier providing Company its nominations pursuant to Attachment 1 hereto and/or Section 3.A(10) below, Company shall timely advise Supplier of the quantity of Supplier’s percentage share of Plant Products that will be available for Supplier to receive from the Plant (“Available Product Volumes”). Company’s determination of Available Product Volumes shall be based on Supplier’s nominations tendered pursuant to the terms of Attachment 1 to this Addendum and historical production volumes and gas composition for existing ▇▇▇▇▇ and current well test data provided by Supplier for newly connected Dedicated ▇▇▇▇▇, projected new volume deliveries expected to commence during the Month, all adjusted for any known upsets, scheduled maintenance outages of which Supplier has provided notice and any other known conditions which could reasonably be expected to have an impact on production volumes in such a manner that the deviation could be reasonably estimated based on then available data. Supplier acknowledges that Company’s estimates and determination of Available Product Volumes will be based on production data provided

Section 3
Right to Take Plant Products and Residue Gas In-Kind

Special Addendum to Dynegy Contract No. 014904 — Ref. No. 095		Page 6

			by Supplier and to the extent such data is inaccurate or does not coincide with actual production flows, Company shall be allowed to adjust the Available Product Volumes accordingly, provided a Supplier representative is advised of such adjustments.
	(7)		Should Supplier fail to arrange for receipt and disposition of some or all of the Available Product Volumes from and at the tailgate of the Plant (as required in Subsection (3) immediately above), Company shall have the right, but not the obligation, to market any volumes with regard to which Supplier has not made such arrangements and if Company elects to do so, Company shall pay Supplier the Proceeds from the sale of such volumes of Supplier’s Plant Products at the tailgate of the Plant. Notwithstanding anything in the definition of “Proceeds” in Section A.1, DEFINITIONS, of the General Terms and Conditions (or any other terms in the Agreement) to the contrary, Company shall retain (**) percent (**)% of the total proceeds received by Company from the sale of any portions of Supplier’s Available Product Volumes, provided same was sold in compliance with the terms of this Section 3.A(7), as Company’s fee for marketing such volumes of Plant Products. The provisions of this Section 3.A(7) shall not be applicable to any volumes of Plant Products which Supplier is entitled to take-in-kind which Company has not advised are available for Supplier’s receipt; i.e., which are not within the Available Product Volumes.
	(8)		Supplier shall account to and pay all Interest Owners for all royalties, overriding royalties, bonus payments, production payments and other payments due on Plant Products taken-in-kind by Supplier.
	(9)		Supplier and Company recognize Company’s inability to redeliver Raw Product the composition of which will exactly match the composition and quantities of the Components attributable and allocable to Supplier’s Gas. Therefore, Company will maintain an “over/short” account to account for the volumes of Components delivered to Supplier each month as against the volumes of same to which Supplier was entitled during such Month. Company and Supplier shall endeavor to keep the over and short volumes as much in balance as possible by making delivery adjustments from time to time. While the Parties may, by mutual agreement, resolve Component imbalances on a volumetric basis, such balancing may be impractical due to the operating procedures and practices of the Product Pipelines. Therefore, unless and until such a mutual agreement is reached and is evidenced in writing, Component imbalances shall be resolved through cash payments pursuant to this Section 3.A(9), as detailed below.

(i)

If, for any reason, (i) the volume of any Component which Supplier is entitled to receive hereunder for a given Month is greater than the quantity of such Component actually delivered for Supplier’s account to the Product Pipeline during such Month, Company shall pay to Supplier a “Cash Out Settlement,” as defined below, or (ii) if the volume of any Component to which Supplier is entitled for a given Month is less than the quantity of such Component actually delivered for Supplier’s account to the Product Pipeline during such month, then Supplier shall pay to Company such a Cash Out Settlement. Company shall include with Supplier’s Monthly statement the volume of any Component that was “over delivered” or “under delivered” during the preceding Month along with a computation of the Cash Out Settlement due Supplier or Company, as applicable with regard to each Component. Payment of any Cash Out Settlement owed to either of the Parties shall be due no later than ten (10) Days following the date of Company’s statement. To the extent Company owes a Cash Out Settlement to Supplier for some Components while Supplier, for that same time period, owes Company a Cash Out Settlement for other Components, the Cash Out Settlements due by each Party shall be netted

Section 3
Right to Take Plant Products and Residue Gas In-Kind

Special Addendum to Dynegy Contract No. 014904 — Ref. No. 095		Page 7

			against each other to determine one, positive Cash Out Settlement that will be paid by the owing Party in the manner provided for above and such net settlements shall not require Company to net all amounts due by each Party under the Agreement as would otherwise be required under Section A.7 (Payments to Supplier).
	(ii)		A “Cash Out Settlement” shall be a payment by the owing Party, in an amount determined as follows, to compensate either the Supplier, as to under deliveries by Company, or the Company, as to over deliveries to Supplier. For each Gallon of any Component that is “over delivered” or “under delivered”, the Cash Out Settlement shall equal the volume, in Gallons, of such Component “over delivered” or “under delivered,” as applicable, converted to the equivalent volume of the applicable Specification Product(s) (determined in accordance with the definition of Specification Products in Section 2 above) multiplied by the “Plant F.O.B. Value” of such Specification Product. The “Plant F.O.B. Value” of such Specification Products shall be equal to the OPIS Index therefor for the Month in which the imbalance arose, less only the following and without further or additional deductions therefrom:

a.

a Fractionation Fee, in cents per Gallon, to be calculated as follows:

		Fractionation Fee   = (**)
		Where:

		Fuel		=		A Gas fuel cost (in $/MMBtu) equivalent to the average Houston Ship Channel Index of INSIDE FERC’S GAS MARKET REPORT, for natural gas for the Month for which the Fractionation Fee is to apply.

	b.		actual storage and loading costs incurred by Company, if any;
	c.		the then current standard published rates and related costs charged by West Texas LPG Pipeline Limited Partnership or its then current successor Product Pipeline (WTLP) for transportation of Raw Product from the Plant to Mont Belvieu, Texas, including WTLP’s standard pipeline tariff charges, pipeline losses, if any, and other related charges imposed by WTLP, or, if rail car or truck transportation is then in use by Company or its Affiliates, actual rail car and truck transportation costs incurred by Company or its Affiliates, on a per Gallon basis, during such Month.

(10)

During any periods when Supplier is taking its share of Plant Products in kind pursuant to this Section 3.A but is not taking its share of Residue Gas in kind, Supplier shall still comply with the terms of Attachment 1 concerning Gas nominations, excluding only those portions which expressly relate to Residue Gas redeliveries, in order to provide procedures for scheduling Plant Product receipts by Supplier.

B. Residue Gas

          From time to time during the term of the Agreement, Supplier may elect to take its percentage share of Residue Gas in-kind at the tailgate of the Plant in lieu of payment of Proceeds attributable thereto as set forth in the Commercial Terms and Conditions (when not giving effect to any amendments set forth in this Addendum). The volume which Supplier will be entitled to receive each Month during any period when such an election is in effect shall be equal to the volume of Residue Gas attributable to the Gas delivered by Supplier under the Agreement during such Month, as determined pursuant to Exhibit D to the Agreement (Allocation Methodology) (“Supplier’s Allocated

Section 3
Right to Take Plant Products and Residue Gas In-Kind

Special Addendum to Dynegy Contract No. 014904 — Ref. No. 095		Page 8

Residue Gas”) multiplied by the Supplier’s Residue Gas Percentage. Such take-in-kind rights shall be subject to the following terms and conditions:

	(1)		Supplier’s initial election, effective as of the Agreement Effective Date set forth above, is to take its percentage share of Residue Gas in kind. Such initial election shall be applicable from the Effective Date and shall remain in effect until Supplier affirmatively elects to terminate such election, in the manner described below.
	(2)		Should Supplier wish to change its then current election (to receive Residue Gas in–kind or the Proceeds attributable thereto, as applicable), Supplier shall give Company at least thirty (30) Days advance written notice of such change. Any change in Supplier’s election shall be effective on the first Day of the Month following the expiration of said thirty (30) Day period. The above initial election and any subsequent change in Supplier’s election must each remain in effect for a period of at least six (6) consecutive Months.
	(3)		Supplier shall be responsible for making its own arrangements for the sale and/or transportation of its share of Residue Gas from and at the tailgate of the Plant. The receiving pipeline shall be responsible for the measurement of Supplier’s Residue Gas.
	(4)		The provisions attached hereto as Attachment 1 to this Addendum, “GAS NOMINATIONS” shall be applicable when Supplier is taking-in-kind its percentage share of Residue Gas. Company shall timely advise Supplier of any events or circumstances of which Company has knowledge that will cause deliveries of Residue Gas to differ materially from the quantities established and confirmed by Company to the receiving gas pipelines pursuant to the procedures set forth in Attachment 1 (“Available Residue Gas”).
	(5)		Should Supplier fail to arrange for receipt and disposition of some or all of the Available Residue Gas from and at the tailgate of the Plant (as required in Subsection (4) immediately above), Company shall have the right, but not the obligation, to market any volumes with regard to which Supplier has not made such arrangements and if Company elects to do so, Company shall pay Supplier the Proceeds from the sale of such volumes of Supplier’s Available Residue Gas at the tailgate of the Plant. Notwithstanding anything in the definition of “Proceeds” in Section A.1, DEFINITIONS, of the General Terms and Conditions (or any other terms in the Agreement) to the contrary, Company shall retain (**) percent (**)% of the total proceeds received by Company from the sale of any portions of Supplier’s Available Residue Gas, provided same was sold in compliance with the terms of this Section 3.B(5), as Company’s fee for marketing such volumes of Residue Gas. The provisions of this Section 3.B(5) shall not be applicable to any volumes of Residue Gas which Supplier is entitled to take-in-kind which Company has not advised are available for Supplier’s receipt; i.e., which are not within the Available Residue Gas volumes.
	(6)		Supplier shall account to and pay all Interest Owners for all royalties, overriding royalties, bonus payments, production payments and other payments due on Residue Gas taken-in-kind by Supplier.
	(7)		Company shall maintain an “over and short account” for Residue Gas deliveries for Supplier’s account. By no later than the 25th Day of each Month (or the first Business Day thereafter if the 25th is not a Business Day), Company shall send a statement to Supplier which shall identify any over or short deliveries for the preceding Month and the cumulative over and short deliveries to Supplier’s receiving pipeline(s). Company

Section 3
Right to Take Plant Products and Residue Gas In-Kind

Special Addendum to Dynegy Contract No. 014904 — Ref. No. 095		Page 9

and Supplier shall endeavor to keep the over and short volumes as much in balance as possible by making flow adjustments Monthly. Should an imbalance exist when the take-in-kind rights provided for in this Section 3.B terminate, then same shall be settled as follows:

	(a)		If Company owes Supplier Residue Gas, Company pay Supplier for such volumes at Supplier’s weighted average sales price received at the Plant for the prior three (3) Months; or
	(b)		If Supplier owes Company Residue Gas, Supplier shall pay Company for such volumes at Company’s weighted average sales price received at the Plant for the prior three (3) Months.

C. Parties’ Obligations and Title to Products & Gas – Amendments to Specific Agreement Terms

     During any period that Supplier has elected to take its percentage share of both Plant Products and Residue Gas in kind, pursuant to the above provisions, then the following specific provisions contained in the Agreement shall not be applicable and the following shall be deemed to be substituted therefor during such periods:

			A particular listed Sub Phase of the Phase V Expansion shall be deemed to be complete when the below described testing, modeling and calculations are performed and demonstrate that the East Side portion of the Gathering System and the Plant have the respective Nominal Design Capacity listed above for that Sub Phase. “Nominal Design Capacity” shall mean a demonstrated capability to gather (at the pressures required under Section 6.A below) and Process, as applicable, the volume of Gas described for such Sub Phase, regardless of whether a volume of Gas equaling such volume is available or was in fact so gathered or processed. Such gathering and processing capabilities shall be deemed to have been demonstrated when the following procedures have been completed:

	(i)		For the Gathering System, evidence of completion of modifications to the affected portions of the Gathering System (including, without limitation and by way of example only, installation of additional pipe, replacement of pipe with larger diameter pipe and addition of compression and other equipment which can increase the capacity of same), including completion of required and industry standard integrity testing and Company specified operating tests for all mechanical and electronic equipment, such that the modified Gathering System can be demonstrated by calculation to be capable of carrying the applicable volumes of Gas based on the Design Parameters applicable to the Gathering System expansion.
	(ii)		For the Plant, completion of performance tests designed and implemented by Company, or its contractors or other designees, sufficient to demonstrate the Plant’s ability to receive and Process the applicable volume of Gas, based on the Basis of Design parameters applicable to the Plant set forth in the Design Parameters applicable to the Plant expansion.

Any physical tests shall be scheduled for a time when the actual operating conditions closely resemble the applicable Design Parameters. If the Gas volumes, Gas composition, or other operating parameters are significantly different enough from the applicable Design Parameters to not be able to determine if the Gathering System or the Plant, as applicable, is capable of the required capacities for the applicable Sub Phase, as set forth in Section 5.A, then the test shall be rescheduled to a time when the conditions more closely resemble the Design Parameters. Or if it appears the actual conditions will not closely resemble the Design Parameters anytime in the near future the capability of the Gathering System or Plant, as applicable, shall be (i) calculated with regard to the Gathering System and (ii) simulated, with regard to the Plant, through Supplier’s or its contractor’s standard process simulator software using the available performance test data. After the Plant has been simulated, using Company’s normally acceptable range of Product recoveries and the Design Parameters, the Plant capacity shall be calculated using this model and mutually acceptable engineering methods.

	(3)		Excused Expansion Delays & Sub Phase Cancellations
			Monitoring of Supplier’s projections and the rights of Company to either delay or cancel a Sub Phase shall be governed by the terms of this Section 5.A(3).

	(i)		Supplier’s current projected production of available Gas from the Dedicated ▇▇▇▇▇ agreed by the Parties to be necessary to justify the completion of each Sub Phase (“Sub Phase Volume Requirement”) is set forth in the table in Section 5.A(1) next to each Sub Phase under the column “Supplier’s Projected Available Gas.” Supplier shall keep Company reasonably informed of any changes to Supplier’s production projections and shall notify Company promptly should Supplier develop or receive any data which could reasonably be interpreted as indicating a material negative change or error in either such projected volumes and/or the dates when same are expected to be available for gathering and Processing under the Agreement such that the Sub Phase Volume Requirement for that Sub Phase would not be met by the then current Completion Date for that Sub Phase.
	(ii)		Supplier shall update its production projections of expected available Gas, with the best data then available to Supplier, when requested to do so by Company, with such requests generally to be made prior to Company making any major contractual, material or capital commitments to a Sub Phase. In any request for such updated projections, Company shall advise Supplier of the critical dates for Company to make such commitments in order to minimize the risk of delay of the completion of the next Sub Phase beyond the applicable Completion Date.
	(iii)		Company shall be entitled to delay a Sub Phase and subsequent Sub Phases if both the following conditions are not satisfied as of the date Company must make any major contractual, material or capital commitments in order to complete that Sub Phase by the then current Completion Date:

	(a)		Commencing with Sub Phase 5.2, the average Daily volumes of Gas from all Dedicated ▇▇▇▇▇, averaged over the most recent Month, equal or exceed the Sub Phase Volume Requirement for the most recently completed Sub Phase; and
	(b)		Supplier’s then current projected volumes of all Gas from all Dedicated ▇▇▇▇▇ to be available as of the Completion Date equal or exceed the applicable Sub Phase Volume Requirement.

			Such a delay shall continue: until above condition “(a)” is satisfied and, as to condition “(b),” to a date reasonably necessary to allow for completion of same only when the volume of such Gas is then expected to equal or exceed the applicable Sub Phase Volume Requirement. Company shall not be required to proceed with a Sub Phase after such a delay if Supplier’s projections are subsequently modified to reflect that Gas equal to or greater than the Sub Phase Volume Requirement will be available for gathering and Processing under the Agreement but the earliest date for availability of such volumes will be three (3) Years or more after the Original Completion Date therefor.
	(iv)		Should any Sub Phase be delayed in compliance with the terms of this Section 5.A(3) the Completion Date shall be extended for a period equal to the period of delay of the subject Sub Phase allowed under the terms of this Section 5.A(3).

Section 5
System & Plant Capacity Expansions

Special Addendum to Dynegy Contract No. 014904 — Ref. No. 095		Page 14

(v)

If Gas from Dedicated Leases is not available for gathering and Processing hereunder in a volume equal to or greater than the Sub Phase Volume Requirement for a particular Sub Phase by the third (3rd) anniversary of the original scheduled Completion Date for such Sub Phase, Company may then permanently cancel such Sub Phase and all subsequently scheduled Sub Phases immediately upon written notice to Supplier.

Unexcused Expansion Delays – Supplier Remedies

	(a)		(**)
			(**)
			(**)

	(b)		Other Remedies
			Subject to the provisions in Section 10, should Supplier serve a notice of default on Company with regard to an Unexcused Expansion Delay and Company has failed to cure same by the latter of ninety (90) Days after the applicable Completion Date or thirty (30) Days after Company’s receipt of Supplier’s written notice of default, Supplier shall have the following remedies available in addition to the monetary compensation set forth in Section Error! Reference source not found.:

	(i)		the right to compel Company’s specific performance of its obligations under this Section 5.A to complete the applicable Sub Phase; and
	(ii)		seek recovery of Supplier’s direct and actual damages arising from such default by Company accruing from and after the date of default and not the date of Supplier’s notice regarding same.

Should Company fail to cure the default by one (1) Year after the Completion Date, then Supplier shall have the additional right to contract with third parties to gather and Process all or any portion of Supplier’s Gas committed under the Agreement, and such volumes as are thereafter diverted to such a third party gatherer shall be released from the Agreement; and/or to terminate the Agreement partially or in its entirety.

B.

Capacity Availability

(1)

Company’s Obligations

Regardless of any compensation to Supplier provided for in Section 5.A above for any delays in completion of the Phase V Expansion, commencing with January 2007, Company shall be obligated to make available sufficient capacity in the Gathering System and Plant, or arrange for such capacity to be made available at the Plant, to

Section 5
System & Plant Capacity Expansions

Special Addendum to Dynegy Contract No. 014904 — Ref. No. 095		Page 15

enable the gathering and processing of a Daily volume of Gas from the Dedicated ▇▇▇▇▇ equal to the “Delivery Volume,” averaged over any one Month. The “Delivery Volume” shall be equal to the Sub Phase Volume Requirement for the last and highest volume Sub Phase which Company is then obligated to have completed by January 2007 (after giving effect to any delays and/or cancellations of any Sub Phases pursuant to Section 5.A(3)). Such Delivery Volume shall thereafter be adjusted upward upon the adjusted Completion Date for any subsequent Sub Phases which Company is obligated to complete after January 2007, with the Delivery Volume to thereafter be the Sub Phase Volume Requirement for that subsequent Sub Phase. Provided, however, Company shall not be in default of its obligations hereunder if any of the following are the cause of Supplier’s inability to deliver or Company’s inability to receive the Delivery Volume into the Gathering System:

	(i)		Supplier does not have a volume of Gas equal to or greater than the Delivery Volume available for, or capable of, delivery to Company for reasons other than (a) insufficient Gathering System and/or Plant capacity or (b) Gathering System pressures at the Delivery Points being in excess of the applicable Maximum Gathering Line Pressure;
	(ii)		Supplier delivering a volume of Gas sufficiently in excess of the Delivery Volume so as to increase the prevailing operating pressures on the Gathering System to pressures in excess of the applicable Maximum Gathering Line Pressure; or
	(iii)		The then prevailing pressures on the Gathering System are in excess of the applicable Maximum Gathering Line Pressure due to Supplier’s demanding Company to provide Low Pressure Service pursuant to Section 9 in a particular manner which Company advised Supplier, in writing prior to the provision of such service, could result in excessive operating pressures on the Gathering System. The exception provided in this Subsection (iii) shall not apply after such an Alternative Low Pressure Service project is in service for at least one full Month and such service does not cause the prevailing pressure on the Gathering System to exceed the applicable Maximum Gathering Line Pressure during such Month, averaged over that Month.

	(2)		Supplier Remedies
			Should Company not be in compliance with its obligations hereunder, Supplier shall provide written notice to Company of same and Company shall have ninety (90) Days from and after the date of Company’s receipt of such notice to remedy such non compliance (excluding delays caused by events of Force Majeure or acts or omissions of Supplier or Supplier’s Affiliates). Should Company thereafter continue to be in non- compliance with this provision, Company shall be deemed to be in default hereunder and Supplier shall have the following remedies with respect to such default:

	(i)		the right to compel Company’s specific performance of its obligations under this Section 5.B;
	(ii)		seek recovery of Supplier’s direct and actual damages arising from such default by Company accruing from and after the date of default and not the date of Supplier’s notice regarding same; and

Should Company fail to cure the default by one (1) Year after the date of default, then Supplier shall have the additional right to contract with third parties to gather and Process all or any portion of Supplier’s Gas committed under the Agreement, and such

Section 5
System & Plant Capacity Expansions

Special Addendum to Dynegy Contract No. 014904 — Ref. No. 095		Page 16

volumes as are thereafter diverted to such a third party gatherer shall be released from the Agreement; and/or to terminate the Agreement partially or in its entirety.

C.		Force Majeure, Supplier Caused Delays & Residue Gas Constraints
		In addition to the delays and/or cancellations of a Sub Phase allowed pursuant to Section 5.A(3) above, the time periods governing Company’s performance of its obligations set forth in various portions of Sections 5.A and 5.B shall be extended for the period of any delay in a cure caused by (a) a force majeure event (which shall be governed by Section A.24 of the General Terms and Conditions); or (b) a delay, breach, act or omission to act of Supplier or any act or omission of any of Supplier’s Affiliates; or (c) curtailments of Gas deliveries into the Gathering System due to insufficient capacity being available, for any reason, in the pipelines accepting redeliveries of Residue Gas from the tailgate of the Plant, such that all available Gas cannot then be processed due to such Residue Gas redelivery constraints. Parties acknowledge that the above specific reference to the applicability of force majeure events as qualifying Company’s time for performance under this Section 5 shall not be construed to, and shall not, limit the legal effect of force majeure events on any of the Parties’ other respective obligations under the Agreement and this Addendum.
6.		Delivery Pressures
A.		Maximum Pressures
		The Gas shall be delivered by Supplier at the Delivery Point(s) at a pressure sufficient to enter the Gathering System against the pressure maintained therein from time to time; provided however:

	(i)		the Company will maintain the Low Pressure System such that the pressure of the Low Pressure System at each Delivery Point delivering to same shall not exceed (**) (**) PSIG, when averaged over any Month, it being understood that such operating pressures may fluctuate substantially within any one Month; and
	(ii)		the Company will maintain its High Pressure System such that the pressure of the High Pressure System at each Delivery Point delivering to same shall not exceed (**) (**) PSIG, when averaged over any Month, it being understood that such operating pressures may fluctuate substantially within any one Month; and
	(iii)		with regard to any Delivery Point on the High Pressure System for which Company is providing Low Pressure Service, in the manner contemplated by Section 8.A(2) (in lieu of physical transfer of same to the Low Pressure System), the Company will maintain the pressure at that Delivery Point such that it shall not exceed (**) (**) PSIG, when averaged over any Month, it being understood that such operating pressures may fluctuate substantially within any one Month.

		The maximum pressures established in (i), (ii) and (iii) immediately above are hereinafter each referred to as the “Maximum Gathering Line Pressure.” In no event shall Supplier deliver Supplier’s Gas at a pressure in excess of the maximum allowable operating pressure of the Gathering System.
B.		Supplier Remedies
		Other than Company’s obligations to complete capacity expansions to comply with its obligations under Section 5, this Section 6.B, sets forth Supplier’s sole remedies for excessive line pressures at any Delivery Points on the Gathering System.

(1)

Notice & Cure: If the actual average Monthly pressure at a Delivery Point exceeds the applicable Maximum Gathering Line Pressure on an average Daily basis over any one (1) Month, Company shall have a period (the “Delivery Pressure Cure Period”) within

Section 6
Delivery Pressures

Special Addendum to Dynegy Contract No. 014904 — Ref. No. 095		Page 17

			which to complete a cure of such excessive pressure condition, such period extending from and after the date of Company’s receipt of a written notice or demand for cure by Supplier (“Notice Date”) to the end of the first full Month the first Day of which is sixty (60) or more Days after such Notice Date. Any such excessive pressure condition shall be cured or remedied for purposes of this Section 6 when the actual average Monthly pressure at a Delivery Point does not exceed the applicable Maximum Gathering Line Pressure on an average Daily basis over any one (1) Month.
	(2)		Failure to Cure: If such condition has not been so remedied by the end of the Delivery Pressure Cure Period, as prescribed above, then effective as of the Notice Date and until the earlier to occur of (i) such condition being cured by Company in the manner required in (1) immediately above; or (ii) (**) .
	(3)		Exceptions: Company shall not have any liability for, and the above remedies shall not be available to Supplier, to the extent any excessive pressure condition arises from: (i) a force majeure event (which shall be governed by Section A.24 of the General Terms and Conditions attached hereto); (ii) any delay, breach, act or omission to act of Supplier or any act or omission of any of Supplier’s Affiliates; or (iii) the then prevailing pressure on the Gathering System is in excess of the Maximum Gathering Line Pressure provided for in Section 6.A above due to Supplier’s demanding Company to provide Alternative Low Pressure Service pursuant to Section 9 in a particular manner which Company has advised in writing prior to the provision of such service could result in excessive operating pressures on the Gathering System, or (iv) from insufficient capacity being available, for any reason, in the pipelines accepting deliveries of Residue Gas from the tailgate of the Plant, such that all available Gas cannot then be processed due to such Residue Gas delivery constraints. Such exception as provided in (iii) above shall not apply after such an Alternative Low Pressure Service project is in service for one full Month and such service does not cause the prevailing pressure on the Gathering System to exceed the applicable Maximum Gathering Line Pressure during such Month, averaged over that Month.

7.		New Well Connections
A.		Notice & Time to Connect

     Company shall be obligated to extend the existing Gathering System to connect any newly completed ▇▇▇▇▇ within the Dedicated Area after receipt of a written notice (the “Connection Notice”) from Supplier that sets forth: (i) a date (the “Readiness Date”) on which Supplier represents the well will be ready for connection to, and delivery of Gas into, the Gathering System; (ii) the Supplier’s projected production rate and pressures expected to prevail after connection to the Gathering System; and (iii) Supplier’s determination of whether the new well is to be connected to the High Pressure System or the Low Pressure System. Supplier shall not send the Connection Notice until Supplier has received and accepted a Texas Railroad Commission drilling permit pursuant to which Supplier intends to drill the well. Subject to any events of force majeure (which will be governed by Section A.24 of the General Terms and Conditions), such connection shall be completed by the latter of (i) (**) Days after Company’s receipt of Supplier’s Connection Notice if the noticed Readiness Date is within that (**) day period; or (ii) the Readiness Date set forth in such Connection Notice. (**) Supplier shall be responsible for obtaining and delivering to Company, as promptly as administratively feasible, the appropriate Texas Railroad Commission form indicating authorization for the connection of the newly connected well.

B.

Wellhead Pressures

     All new ▇▇▇▇▇ shall be connected to the High Pressure System unless Company determines, in its sole but reasonable judgment made only after consulting with Supplier, that the anticipated

Section 7
New Well Connections

Special Addendum to Dynegy Contract No. 014904 — Ref. No. 095		Page 18

volumes and Delivery Point pressures for such new well are such as to make such a connection inadvisable and in such case the new well will be connected to the Low Pressure System.

C.

Costs to Connect

	(1)		Company shall bear the entire Connect Costs for new ▇▇▇▇▇ connected pursuant to Section 7.A above if both: (i) Supplier’s Gas commences flowing through such new connection within ninety (90) Days of Company’s completion of the connection; and (ii) the total “Available Gas” (as defined in Section 7.C(4) below) from such well, after completion of the new connection, equals at least (**) Mcf per Day for each one mile of pipeline installed to complete such connection with a shut-in wellhead pressure of at least (**) PSIG.
	(2)		Supplier shall bear all Connect Costs incurred by Company, and reimburse Company for same, if the conditions for Company to bear 100% of same set forth in Section 7.C(1) above are not satisfied and either: (i) the Available Gas from such well is less than (**) Mcf per Day for each one mile of pipeline installed to complete such connection; or (ii) if the shut-in wellhead pressure of the well is less than (**) PSIG.
	(3)		If a new well has a shut-in wellhead pressure of at least (**) PSIG but the Available Gas therefrom is equal to or greater than (**) Mcf per Day but less than (**) Mcf per Day (both per each mile of pipeline installed to complete the connection), then Supplier shall reimburse Company a prorated portion of all Connect Costs incurred by the Company with regard to such well, with Supplier’s prorated share of same being determined as follows: (x) divide the total Available Gas by the number of miles of the pipeline installed (“MCF Per Mile”); (y) divide the MCF Per Mile by (**) and then deduct the result of same from 1.0 (“Supplier’s Share”); and (z) multiply the total Connect Costs by such Supplier’s Share.
	(4)		“Available Gas,” for the purposes of this Section 7, shall be determined based on the actual average daily volumes of Gas delivered to the new Delivery Point during the first 30 Days after the first date of flow of Gas therefrom into the Gathering System.
	(5)		If any of the Available Gas is attributable to a Production Interest in a Dedicated Well other than those dedicated to the Agreement as listed in listed in Exhibit B to the Agreement under “Current Dedicated ▇▇▇▇▇,” and any of the Gas attributable to such non-dedicated Production Interests is diverted by the Production Interest Owner during the first (**) Years from and after the date of connection (“Cost Recovery Period”) of same to the Gathering System, Supplier shall reimburse Company for the Connect Costs incurred by Company in connection with such well, based on the following formulae:
