D. Effective January 1, 1997, the First Amendment was amended (the "SECOND AMENDMENT") solely with respect to certain mineral leases, the production from which was dedicated for Processing at the Venice Plant of Venice Energy Services Company, L.L.C., to confirm SWEPI's ownership of the Gas Processing Rights for those mineral leases. E. Effective January 1, 1998, the Second Amendment was amended in its entirety (the "THIRD AMENDMENT") to (1) recognize and confirm SWEPI's ownership of the Producers' Gas Processing Rights associated with the Equity Gas attributable to the leases listed on Exhibit "A" to such Third Amendment, including the right to Process Equity Gas, and receive the benefits therefrom, with respect to such leases; (2) confirm that the transfer of such rights to SWEPI was and is binding on Producers as SOI's successors and assigns, and their respective Affiliates, notwithstanding non-compliance by Producer or SWEPI with respect to any provision concerning annual notification requirements of the First Amendment; (3) provide that SWEPI shall be conveyed without further act, the Gas Processing Rights for Equity Gas from any Lease upon the earlier of that point in time (x) when Gas production from such Lease is committed to be transported in an Upstream Pipeline, (y) when such Lease (or unitized portion thereof) begins 1 Gas production to an Upstream Pipeline, or (z) when SWEPI requires a written dedication of Gas Processing Rights for a Lease in connection with SWEPI's efforts to provide Processing capacity for Gas production from such Lease, regardless of whether Exhibit A is thereafter amended to include Leases; and (4) to make such other changes to the Conveyance as specified in the Third Amendment. F. Effective January 12, 1998, SWEPI assigned to Tejas Holdings, LLC all of its rights under the Third Amendment and Tejas Holdings, LLC subsequently assigned all of such rights to Tejas Natural Gas Liquids, LLC. G. Effective August 1, 1999, the Third Amendment was amended and, as so amended, restated in its entirety (the "FOURTH AMENDMENT") to clarify the respective rights and obligations of the Processor and Producers thereunder. H. Effective September 30, 1999, Tejas Natural Gas Liquids LLC changed its name to Enterprise Natural Gas Liquids, LLC. I. Effective October 31, 1999, Enterprise Natural Gas Liquids, LLC merged with and into Enterprise Products Operating L.P., with Enterprise Products Operating L.P. being the surviving entity of such merger. J. Effective March 31, 2001, Enterprise Products Operating L.P. assigned all of its rights under the Fourth Amendment to its wholly-owned subsidiary, Enterprise Gas Processing, LLC, which assignment was in all respects approved and consented to by Producers. K. Effective April 1, 2001, the Fourth Amendment was amended and, as so amended, restated in its entirety (the "FIFTH AMENDMENT") to incorporate certain changes in the respective rights and obligations of the Processor and Producers thereunder. L. Effective September 18, 2002, SGOM ratified and joined in the Fifth Amendment as a Producer Party. M. Effective March 1, 2003, the Fifth Amendment was amended and, as so amended, restated in its entirety (the "SIXTH AMENDMENT") to incorporate certain changes in the respective rights and obligations of the Processor and Producers thereunder. L. The Parties desire to further amend the Sixth Amendment to incorporate further changes in their respective rights and obligations thereunder and to restate the Conveyance in its entirety.

If Processor and Producer do not enter into such mutually agreeable Processing agreements within the 15-day period, then Producer shall be free to deliver and/or dedicate said New Volumes, in its sole discretion, and for any purpose, to a Third Party. 3. ASSIGNMENT OF GAS PROCESSING RIGHTS. 3.1 GRANT OF PROCESSING RIGHTS. Subject to the other provisions of this Agreement, Producers hereby grant, sell, transfer, convey and assign to Processor the following (the "GAS PROCESSING RIGHTS"): (1) the exclusive right to process any and all Equity Gas for the extraction and retention of liquefiable hydrocarbons and other constituents of Raw Make and/or Products; (2) all title, interest and /or ownership in Raw Make and/or Products recovered from Processing Equity Gas; and (3) the right and option to assume, subject to this Agreement, any contract for the Processing of Equity Gas, including all of a Producer's rights and obligations therein, that is assumed by a Producer in connection with the acquisition of a Lease, provided that Processor has given written notice to the Producer of Processor's exercise of its option to assume such contract within 90 days of Processor's receipt of written notice from the Producer that Producer has assumed or intends to assume such contract in connection with its acquisition of a Lease, which said notice shall be given by Producer to Processor at a reasonable time. It is the intention of the Parties to confer on the Processor, subject to this Agreement, the Gas Processing Rights, and the economic benefits and burdens to be derived therefrom, for all Gas from Leases, whether derived from (a) Leases which are currently owned by a Producer and which are currently Dedicated Leases or which subsequently become Dedicated Leases or (b) Leases which are subsequently acquired by a Producer and which are Dedicated Leases as of the date of acquisition or which subsequently become Dedicated Leases while still owned by a Producer, subject only to (i) rights previously granted by the transferors of subsequently acquired Leases to Third Parties as provided in Section 3.3 and (ii) the right of Producers under Section 8 3.2 to transfer, free of Processor's rights under this Agreement, Leases that at the time of transfer are not Dedicated Leases. 3.2 ATTACHMENT OF GAS PROCESSING RIGHTS. This conveyance of Gas Processing Rights shall be irrevocable as to Dedicated Leases, except for Excluded Leases. A Lease shall be considered a Dedicated Lease upon the earliest of that point in time (the "COMMITMENT DATE"): when (i) when a well is spud on the Lease; (ii) a Plan of Exploration or similar document including all or part of the Lease is submitted or amended to the appropriate regulatory agency and a well is or has been spud on any of the Leases included in the Plan of Exploration; (iii) a Development Operations Coordination Document or similar document including all or part of the Lease is submitted or amended to the appropriate regulatory agency; or (iv) Gas production begins from the Lease. A Lease acquired by a Producer shall become a Dedicated Lease on the later of (1) the effective date of the acquisition of such Lease by Producer if at any time prior to such acquisition an event occurred that would constitute a Commitment Date had the Producer owned an interest in such Lease at the time of such event, or (2) the later Commitment Date for such Lease. Dedicated Leases as of August 1, 1999 are listed on Exhibit A. Producer shall have the right to transfer, sell, assign, exchange or otherwise alienate a Lease free of any obligations under this Agreement and without any obligation to the Processor with respect to the Lease prior to its Commitment Date. In the case of a transfer, sale, assignment, exchange or other alienation of a Lease or an interest therein to a Third Party pursuant to what is generally known in the petroleum industry as a "perform to earn" contract, said transfer, sale, assignment, exchange or other alienation shall for purposes of this Agreement be considered to have taken place on the date on which such fully executed and delivered perform to earn contract is effective, not the later date on which the rights earned under said perform to earn contract are earned, nor the date on which said transfer, sale, assignment, exchange or other alienation is executed or made effective; provided, however, in the event any such Lease or interest therein reverts to Producer, it shall again be subject to this Agreement. 3.3 PRODUCERS' NONDISTURBANCE COVENANT; PRIOR RESERVATIONS OR CONTRACTS. Excepting Producers' rights to sell, assign, exchange or otherwise alienate Leases as provided for in Section 3.2 and Producer's rights to enter into agreements which could cause Gas to be excluded from Equity Gas under Sections 1.12(i) through 1.12(viii), Producers agree not to make any assignment or conveyance of, or enter into any other obligation concerning Gas Processing Rights with respect to, any Lease to the prejudice of Processor or its rights under this Agreement. Producers further agree that, in connection with the acquisition of a Lease, they will not permit the transferor to reserve to itself or convey to any Person other than a Producer any right to Process Equity Gas to be produced from the Lease. However, as to any Lease acquired by a Producer subject to a prior grant of rights to Process Equity Gas to be produced under the Lease to Persons other than a Producer, Processor's rights under this Agreement shall be subject to such rights previously granted, to the extent thereof. 3.4 PROCESSOR'S RIGHT TO CONSUME PTR. In conveying the Gas Processing Rights under this Agreement, Producers acknowledge and agree that the Equity Gas Processed in a Plant will be subject to a PTR incidental to the exercising of the Gas Processing Rights, and Producers hereby grant to Processor the rights to consume Equity Gas as PTR associated with Processor's Retrograde and Products. 9 * CONFIDENTIAL TREATMENT REQUESTED. THE REDACTED MATERIAL HAS BEEN SEPARATELY FILED WITH THE COMMISSION, AND THE APPROPRIATE SECTION HAS BEEN MARKED AT THE APPROPRIATE PLACE AND THE MARGIN WITH A STAR (*). 3.5 TITLE TO RAW MAKE, PRODUCTS, PROCESSOR'S RETROGRADE AND PTR. Producers hereby (i) represent and warrant to Processor that title to the liquefiable hydrocarbons in Equity Gas is and will be free from all production burdens, liens and adverse claims, (ii) warrant their right to sell the same and (iii) agree to indemnify, defend and hold harmless Processor against all claims to said liquefiable hydrocarbons arising (x) by, through, or under Producers or (y) prior to Producers' delivery of said liquefiable hydrocarbons to Processor. The transfer of title to the extracted liquefiable hydrocarbons shall pass to Processor at the meters for Raw Make and/or Products, as appropriate, of the applicable Plant. The Processor and Producers acknowledge and agree that title to PTR does not pass to Processor. 3.6 LIMITATIONS ON UPSTREAM PROCESSING. 3.6.1 PRODUCER'S OPERATIONAL REQUIREMENTS. Producers agree that, except as dictated by operational requirements, including the need to meet pipeline specifications (excepting when such need will be met by Processor under this Agreement), they will not remove or permit to be removed any liquefiable hydrocarbons from Equity Gas upstream of the Plants except for (i) liquefiable hydrocarbons that condense from * the Gas during transportation to the Plants and (ii) [REDACTED]. 3.6.2 PROCESSOR'S EXCLUSIVE RIGHTS. The rights granted to Processor herein are exclusive, and Producers shall use their commercially reasonable efforts to ensure that no owner or operator of an Upstream Pipeline shall have or exercise any right or opportunity to Process, or extract Products from, Equity Gas as to which the Gas Processing Rights have been conveyed to Processor under this Agreement. 3.6.3 NGL BANKS. In the event that any Upstream Pipeline or the shippers on an Upstream Pipeline institute a bona fide mechanism to mitigate inequities that may occur between shippers on such Upstream Pipeline as a result of such shippers' Gas streams containing different liquifiable hydrocarbon compositions being commingled in a pipeline with multiple delivery points located upstream of Gas Processing Plants (an "NGL BANK"), Producers and Processor agree to participate in the NGL Bank so as to confer on Processor the financial benefits and detriments related to such liquifiable hydrocarbons under the terms of the NGL Bank. Producers and Processor agree to execute and deliver to one another such instruments as may be necessary or useful and to take such further actions as may be reasonably necessary to carry out or further evidence the intent of this Section 3.7. Pending execution of such instruments, Producers shall not be required to curtail any Equity Gas production. However, Producers shall ensure Processor receives all financial benefits and detriments referenced in this Section 3.7 from the date of initiation of the NGL Bank. 10 4. PROCESSOR'S OBLIGATION TO PROCESS AND REDELIVER; LIMITATIONS. 4.1 PROCESSOR'S OBLIGATION TO PROCESS AND REDELIVER RESIDUE GAS. Subject to the provisions of this Agreement, throughout the term of this Agreement and for any subsequent period of time as contemplated by Section 2.3.1, Processor agrees to Process, or cause to be Processed, all Equity Gas. After Processing Equity Gas and/or Slug Liquids and the recovery of the Raw Make, Products and Processor's Retrograde therefrom, Processor shall deliver or cause to be delivered Producers' Residue Gas to Producers or Producers' designee at the applicable Plant Redelivery Point. 4.2 TEMPORARY CESSATION OF PROCESSING. If at any time or from time to time Processor reasonably determines that the temporary cessation of Processing Equity Gas at a Plant would not cause curtailment of the applicable Equity Gas, then Processor shall have the option, in its sole discretion, to temporarily cease Processing at that Plant. Processor shall provide Producer with at least two business days' notice of any such election to temporarily cease Processing or to subsequently recommence Processing at a Plant and shall not change its election more than two times in a month. 4.3 REFUSED VOLUMES. 4.3.1 INSUFFICIENT CAPACITY; OPTION TO REFUSE VOLUMES. If Processor accepts or has previously accepted for Processing Equity Gas from a Dedicated Lease, it may not thereafter refuse to Process any Equity Gas produced from or allocated to such Dedicated Lease ("EXISTING EQUITY GAS") on the basis of insufficient Plant capacity, except as provided hereafter in this Section 4.3.1. Processor may, at its option, to be exercised by Processor as soon as reasonably practicable by providing the applicable Producer with written notice of such election, elect to Process or not to Process a volume of ("REFUSED VOLUMES"): (i) Equity Gas produced from or allocated to a Dedicated Lease from which it has not previously accepted Equity Gas for Processing ("NEW EQUITY GAS") that exceeds or that Processor reasonably expects to exceed its available Processing capacity at a Plant; and/or (ii) Existing Equity Gas to the extent and only to the extent that (a) such Existing Equity Gas exceeds or is reasonably expected by Processor to exceed 120 percent of the most recent 12 month average MCF volume of the aggregate of all such Existing Equity Gas delivered to a Plant, as measured at the applicable Field Delivery Point(s), or if a 12 month volumetric history is not available for such Existing Equity Gas, then 120 percent of the peak volume for such Existing Equity Gas from the most recent 12 month forecast provided by Producer, and (b) such Existing Equity Gas exceeds or is reasonably expected by Processor to exceed its available processing capacity at a Plant. If Processor elects not to Process such Refused Volumes, Producer may, nonetheless, by written notice to Processor, require that Processor and Producer enter into exclusive good faith 11 negotiations for a period of 90 days from the date of the notice to negotiate the terms and conditions of a mutually agreeable alternative Processing arrangement for the Refused Volumes that would allow Processor in its sole judgment to economically acquire or construct additional capacity at the Plant. If within the 90-day period Processor and Producer are unable to negotiate and execute a definitive agreement related thereto, Producer shall be free to negotiate and enter into an agreement with any one or more Third Parties for Processing services ("THIRD PARTY CONTRACT") for the Refused Volumes that Processor has elected not to Process hereunder; provided that (i) the terms of each such Third Party Contract are, taken as a whole, more favorable to the Producer than the terms for Processing services last offered by Processor to Producer during the 90-day period, and (ii) each such Third Party Contract provides that Producer may at any time freely assign such Third Party Contract to Processor, and that Processor shall succeed to all of Producer's rights and obligations under the Third Party Contract that arise as of and after the effective date of any such assignment. 4.3.2 OPTION TO REACQUIRE REFUSED VOLUMES. Processor shall have the option, exercisable by written notice to Producer given at any time on or before the later of the first anniversary of the (a) effective date of a Third Party Contract, (b) date on which said Third Party Contract was fully executed and delivered or (c) date Gas was first delivered under said Third Party Contract, to take an assignment from Producer of a Third Party Contract, effective on the first day of the third month following the month in which the notice is given to Producer, provided that Processor shall promptly reimburse Producer for all direct costs that were incurred by Producer in connection with acquiring the Third Party Contract. Promptly following the execution and delivery of a Third Party Contract, Producer shall furnish Processor with a copy of the Third Party Contract and, to the extent not included in the Third Party Contract, an itemized statement showing all of the direct costs incurred by Producer in connection with acquiring the Third Party Contract. Equity Gas that becomes subject to a Third Party Contract as Refused Volumes shall, upon termination of such Third Party Contract, again be subject to this Agreement as Existing Equity Gas. 4.4 EXCLUDABLE GAS. 4.4.1 OPTION TO EXCLUDE CERTAIN GAS. Processor may, at its option, elect to Process or not Process all or any part of New Equity Gas that contains or that Processor reasonably expects to contain less than or equal to 0.5 GPM of ethane and heavier hydrocarbons as measured at a Field Delivery Point ("EXCLUDABLE GAS") and agrees to provide the applicable Producer with notice of such election as soon as reasonably practicable. Processor may not elect to refuse to Process any Existing Equity Gas under the provisions of this Section 4.4.1 as Excludable Gas. If Processor elects not to Process such Excludable Gas, Producer may, nonetheless, by written notice to Processor, require that Processor and Producer enter into exclusive good faith negotiations for a period of 90 days from the date of the notice to negotiate the terms and conditions of a mutually agreeable alternative Processing arrangement for the Excludable Gas. If within the 90-day period Processor and Producer are unable to negotiate and execute a definitive agreement related thereto, Producer shall be free to negotiate and enter into an agreement with any one or more Third Parties for Processing services ("THIRD PARTY CONTRACT") for the Excludable Gas that Processor has elected not to Process hereunder; provided that (i) the terms of each such Third Party Contract are, taken as a whole, more favorable to the 12 Producer than the terms for Processing services last offered by Processor to Producer during the 90-day period, and (ii) each such Third Party Contract provides that Producer may at any time freely assign such Third Party Contract to Processor, and that Processor shall succeed to all of Producer's rights and obligations under the Third Party Contract that arise as of and after the effective date of any such assignment. 4.4.2 OPTION TO REACQUIRE EXCLUDABLE GAS. Processor shall have the option, exercisable by written notice to Producer given at any time on or before the later of the first anniversary of the (a) effective date of a Third Party Contract, (b) date on which said Third Party Contract was fully executed and delivered or (c) date Gas was first delivered under said Third Party Contract, to take an assignment from Producer of a Third Party Contract, effective on the first day of the third month following the month in which the notice is given to Producer, provided that Processor shall promptly reimburse Producer for all direct costs that were incurred by Producer in connection with acquiring the Third Party Contract. Promptly following the execution and delivery of a Third Party Contract, Producer shall furnish Processor a copy of the Third Party Contract and, to the extent not included in the Third Party Contract, an itemized statement showing all of the direct costs incurred by Producer in connection with acquiring the Third Party Contract. Equity Gas that becomes subject to a Third Party Contract as Excludable Gas shall, upon termination of such Third Party Contract, again be subject to this Agreement as Existing Equity Gas. 4.5 SUSPENSION IN CASE OF DANGEROUS CONDITION. If any of Producers' operations or any of the Equity Gas or Slug Liquids delivered hereunder create a condition that, in the exclusive judgment of Processor, may endanger a Plant or property of Processor or the lives or property of Processor's employees or any Third Party, Processor may, without liability, immediately discontinue receipt of such Equity Gas and/or Slug Liquids, as the case may be, until the condition has been remedied to the reasonable satisfaction of Processor. 5. SPECIFICATIONS FOR GAS AND SLUG LIQUIDS. 5.1 QUALITY SPECIFICATIONS. Producers shall deliver Equity Gas and Injected Liquids to each Field Delivery Point in conformity with the specifications (except for all specifications for liquefiable hydrocarbon content) of the applicable Upstream Pipeline (the "QUALITY SPECIFICATIONS"). 5.2 TESTING. The determination as to the conformity of Equity Gas or Injected Liquids to the Quality Specifications shall be made by Processor in accordance with generally accepted procedures of the Gas Processing industry. Such determinations shall be made as often as Processor deems necessary, and Producer may witness such determinations or make joint determinations with its own appliances. If, in a Producer's judgment, the result of any such test or determination is inaccurate, Processor, at such Producer's request, will again conduct the questioned test or determination, and the costs of such additional test or determination shall be borne by said Producer unless same shows the original test or determination to be materially inaccurate. 13 5.3 OFF-SPEC DELIVERIES. If any of Equity Gas or Injected Liquids delivered at a Field Delivery Point fail to meet the Quality Specifications ("OFF-SPEC DELIVERIES"), Processor, subject to the provisions of Sections 5.4, 5.5 and 5.6, at its sole option, may accept, or notify the appropriate Producer to discontinue or curtail, such Off-Spec Deliveries. Processor's acceptance of Off-Spec Deliveries shall not be deemed a waiver of Processor's right to later reject such Off-Spec Deliveries, nor shall acceptance of Off-Spec Deliveries from one Field Delivery Point require Processor to accept similar Off-Spec Deliveries from any other Field Delivery Point. 5.4 NOTIFICATION OF NON-CONFORMITY; REJECTION OF DELIVERY. Processor shall notify a Producer of any Off-Spec Deliveries, and Producer shall make a diligent effort to conform such Equity Gas and/or Injected Liquids to the Quality Specifications. If any Producer reasonably concludes that it cannot economically deliver Equity Gas and/or Injected Liquids conforming to the Quality Specifications, then such Producer shall so advise Processor in writing within 30 days after receipt of Processor's notice. Within 30 days after receipt of Producer's notice, Processor shall give notice to the Producer in writing of its election to accept or reject such Off-Spec Deliveries. If Processor rejects such Off-Spec Deliveries, then upon receipt of Processor's notice of same by such Producer, Processor may, without liability, refuse to accept delivery of such Off-Spec Deliveries until such time as the Off-Spec Deliveries conform to the Quality Specifications or Processor subsequently notifies such Producer of its acceptance of the Off-Spec Deliveries. 5.5 ACCEPTANCE OF NONCONFORMING PRODUCT. If Processor accepts such Off-Spec Deliveries, Processor, after written notice to a Producer as specified in Section 5.4, may charge such Producer any reasonable costs incurred by Processor to monitor the quality of Equity Gas and/or Injected Liquids and bring them within the Quality Specifications. Processor shall invoice such Producer on a monthly basis for any such costs, the payment of which shall be due and payable within 30 days after the Producer's receipt thereof. 5.6 PROCESSOR'S LIMITED COMMITMENT TO ACCEPT NON-CONFORMING PRODUCT. Notwithstanding the provisions of Sections 5.3, 5.4 and 5.5, Processor agrees that it will use reasonable efforts to continue acceptance of a Producer's Off-Spec Deliveries for Processing in those cases where (i) Section 4.6 does not apply and (ii) the acceptance of such Off-Spec Deliveries does not (x) cause damage to a Plant, (y) render a Plant unable to meet applicable specifications of the pipelines receiving Residue Gas at the Plant Redelivery Points or of the purchaser or transporter of the Products from the Plant, or (z) cause the Plant to violate applicable emissions permits or other regulatory requirements. 5.7 SPECIFICATIONS FOR RESIDUE GAS REDELIVERED BY PROCESSOR. Processor will take commercially reasonable actions within its control to assure that the Residue Gas redelivered by Processor complies with the specifications in effect on the date of delivery to the pipeline transporter receiving such Residue Gas at the applicable Plant Redelivery Point so long as the Equity Gas attributable to such Residue Gas met the same specifications (except for all specifications for liquefiable hydrocarbon content) at the applicable Field Delivery Point. 14 * CONFIDENTIAL TREATMENT REQUESTED. THE REDACTED MATERIAL HAS BEEN SEPARATELY FILED WITH THE COMMISSION, AND THE APPROPRIATE SECTION HAS BEEN MARKED AT THE APPROPRIATE PLACE AND THE MARGIN WITH A STAR (*). 5.8 OFF SPEC PIPELINE. Nothing in this Agreement shall require Processor to accept delivery of any Gas that does not conform to the Quality Specifications at the Plant Delivery Point. 6. CONSIDERATION. 6.1 PAYMENT. For each calendar month during the term of this Agreement, Processor agrees, for each Plant, to pay to each of the respective Producers delivering Equity Gas to such Plant, a cash amount equal to the product of: (1) the Consideration Basis, as defined in Section 6.2, for the respective Plant; and (2) the PTR for (1) such Producer's Equity Gas Processed at such Plant and (2) any Processor's Retrograde associated with such Producer's Equity Gas. 6.2 CONSIDERATION BASIS. For purposes of Section 6.1, the term "CONSIDERATION BASIS" shall mean, and be defined as, for each calendar month * during the term of this Agreement, the [REDACTED]. 6.3 CONSIDERATION TIMING. Processor shall pay to Producer the applicable cash consideration set forth in Section 6.1 (as same may be adjusted pursuant to Section 6.6 of this Agreement) no later than the third to last business day of the second month following the month in which the subject PTR and Processor's Retrograde is delivered to a Plant, such payment to be made by wire transfer of immediately available funds to an account designated from time to time by Producers at least fifteen days prior to the date any such payment is due and payable by Processor. In the event a particular Producer owes an amount hereunder to Processor, it may be netted by Processor against the applicable amount owing to such Producer hereunder. * 6.4 CONSIDERATION BASIS UPDATES. [REDACTED]. 6.5 PROCESSOR PROVIDED PTR. Producers and Processor acknowledge and agree that, in lieu of, and as an alternative to, any cash payment required under Section 6.1 to be paid by Processor to Producers, Processor shall have an election to provide, from time to time, PTR at a particular Plant for Processor's own account in respect of all of Producer's Equity Gas Processed at such Plant. Processor agrees that any such election to provide PTR for its own account shall be effective on the first day of a month, and that Processor shall provide Producers with at least fifteen days' prior written notice of any such election. If, for any particular month, Processor has elected to provide PTR for its own account, Processor shall not be entitled to rescind, revoke or change such election for such month. Processor agrees to provide any notifications with respect 15 * CONFIDENTIAL TREATMENT REQUESTED. THE REDACTED MATERIAL HAS BEEN SEPARATELY FILED WITH THE COMMISSION, AND THE APPROPRIATE SECTION HAS BEEN MARKED AT THE APPROPRIATE PLACE AND THE MARGIN WITH A STAR (*). to such Processor-provided PTR that may be required by an Upstream Pipeline to which Processor delivers such PTR. 6.6 CONSIDERATION ADJUSTMENT. (a) The cash amount of the total of all payments to be made by Processor to each of the respective Producers calculated under Section 6.1 (the "CONSIDERATION PAYMENT") shall be adjusted, proportionately for each such payment, for each calendar month during the term of this Agreement as follows (the "CONSIDERATION ADJUSTMENT"): * (i) [REDACTED]; or * (ii) [REDACTED]; or * (iii) [REDACTED]; or * (iv) [REDACTED]. (b) Processor shall provide Producer with an estimate of the Average Net Margin and the Products Volume for each calendar month, in writing, no later than the fifth business day of the next calendar month following the month in which the PTR and Processor's Retrograde is delivered to a Plant. (c) For purposes of this Section 6.6, the following definitions shall be applicable. (i) "AVERAGE NET MARGIN" means the Average Gross Margin less the Calculated Expenses. (ii) "AVERAGE GROSS MARGIN" means (A) the Products Value minus the PTR Value divided by (B) the Products Volume. (iii) "PRODUCTS VALUE" means the Products Volume multiplied by the Products Price. (iv) "PRODUCTS PRICE" means: (A) for natural gas * liquids, [REDACTED]; and (B) for condensate, * [REDACTED], divided by 42. 16 * CONFIDENTIAL TREATMENT REQUESTED. THE REDACTED MATERIAL HAS BEEN SEPARATELY FILED WITH THE COMMISSION, AND THE APPROPRIATE SECTION HAS BEEN MARKED AT THE APPROPRIATE PLACE AND THE MARGIN WITH A STAR (*). (v) "PRODUCTS VOLUME" means the total volume of Products, in Gallons, allocated to Processor for Equity Gas in a calendar month, * [REDACTED]. (vi) "PTR VALUE" means the sum, for a calendar month, of the product of the PTR and the Consideration Basis for each Plant where Equity Gas is Processed during such calendar month plus the total amount paid by Processor to Producers for transportation of PTR and Processor's Retrograde for such calendar month as set forth in Section 7 below. (vii) "CALCULATED EXPENSES" means the monthly expenses associated with the Processing of Equity Gas, in cents per Gallon, calculated for each calendar month using the following formula: * [REDACTED] Where: X equals the index price, in dollars per million BTUs, * [REDACTED]; and * Y equals [REDACTED]. (d) If for any reason any of the price indexes used in this Section 6.6 cease to be published, then such affected index price(s) shall, if available, be obtained from an alternative industry publication (private or government) which publishes the same pricing information. If an index price is no longer available, then Producer and Processor shall, within 60 days of the first day of the month that the cessation occurred, agree upon an alternate pricing mechanism for such affected index price(s). The alternate pricing mechanism agreed upon shall apply retroactively to the first day of the month that the former index terminated. If the Parties cannot agree on an alternate pricing mechanism within the 60 day period, then the issue of how such affected index price(s) should be determined shall be a Dispute under this Agreement. It is the intent of the Parties that any replacement methodology or index shall resemble as closely as possible the index being replaced. 6.7 CONSIDERATION REDUCTION. For each calendar month during the term of this Agreement, and any continuation thereof under Section 2.3.1, each Consideration Payment shall be proportionately reduced by an amount equal to the product of V and W ("CONSIDERATION REDUCTION"); Where: 17 * CONFIDENTIAL TREATMENT REQUESTED. THE REDACTED MATERIAL HAS BEEN SEPARATELY FILED WITH THE COMMISSION, AND THE APPROPRIATE SECTION HAS BEEN MARKED AT THE APPROPRIATE PLACE AND THE MARGIN WITH A STAR (*). * V initially equals [REDACTED]; and * W equals [REDACTED] 7. PTR AND PTR TRANSPORTATION. Producers shall provide, or cause to be provided, the PTR and the transportation for (i) the PTR associated with the Processing of Equity Gas and (ii) Processor's Retrograde from the wellhead to the Plant Delivery Point, for all Equity Gas and Processor's Retrograde subject to the payment of consideration under Article 6. Producers shall also pay for all necessary facilities to cause the Equity Gas and/or Injected Liquids to meet the Quality Specifications and all other costs associated with delivering such PTR and Processor's Retrograde to the Plant Delivery Point. Processor shall pay Producers, for transportation of the PTR and Processor's Retrograde referenced in this Article 7, an amount equal to three cents ($0.03) per MMBTU. If Processor provides PTR for its own account under Section 6.5, Processor shall provide, or cause to be provided, transportation for such PTR at its sole expense. 8. ROYALTY. 8.1 RESPONSIBILITY FOR ROYALTY PAYMENTS. (a) As between Processor and Producers, (i) Producers shall be and remain fully liable for, and shall be fully responsible for remitting any and all payments to the Department of the Interior, the Minerals Management Service, the States of Louisiana, Texas, Mississippi, Alabama and Florida, any other governmental agencies or authorities, and any private lessors who are not federal or state lessors in respect of, any and all federal, state or local royalties and/or severance taxes due on any or all hydrocarbon production of Producers or which in any way relate to, or are in connection with, any of the transactions under this Agreement, including, without limitation, any such federal, state or local royalties and/or severance taxes on, relating to, or calculated on the basis of, any value of (x) the PTR used by Processor, (y) the Products extracted from the Equity Gas and (z) Processor's Retrograde (collectively, "ROYALTY CHARGES"), and (ii) Processor shall have no liability for or in respect of any such Royalty Charges. (b) Producers hereby agree to hold harmless and indemnify Processor (and its Affiliates) from and against, and shall fully and promptly reimburse Processor (and its Affiliates) for, any and all claims, demands, and causes of action of any kind and all losses, damages, costs, and expenses (including court costs and reasonable attorneys' fees) arising from, relating to, or in connection with, any Royalty Charges. 18 8.2 DELIVERY OF ROYALTY TAKEN IN KIND. Any request by a private, state or federal governmental lessor to take royalty production in kind for any Raw Make or Products recovered through Processing shall, if lawful, be fulfilled by Processor's delivery to the lessor or its designee of such in kind royalty at a specified location, all as may be required in accord with properly promulgated notices, regulations, or lease terms and to the extent that such delivery by Processor is approved (if required) by private, state or federal lessor. In such case, Processor shall be entitled to recover all costs allowed by statute, regulation or lease term including but not limited to costs of transportation and administrative services. In the event that Processor is prohibited from fulfilling such in kind royalty requests by the private state or federal lessor, then Processor shall be relieved of such obligation but shall tender to Producers an amount of Raw Make or Products recovered from Processing sufficient to fulfill such obligations at a mutually agreeable delivery point. 8.3 COMPLIANCE WITH FEDERAL ACTS. As between Processor and Producers, Processor agrees to fulfill Producers' obligation under Section 8(b)(7) of the Outer Continental Shelf Lands Act of 1978 by offering Processor's Retrograde and Products recovered through processing at the market value and point of delivery provided by regulators to small and independent refiners as defined in the Emergency Petroleum Allocations Act of 1973. Processor shall be entitled to retain the proceeds derived from such sale. In the event Processor is prevented for any reason from fulfilling this obligation, Processor shall tender to Producers' sufficient volumes of such Processor's Retrograde and Products sufficient for Producers themselves to fulfill such obligation, and Producers shall reimburse Processor for such liquids at a mutually agreed price which shall include the cost of handling and administration of such sales. Producer shall be entitled to retain the proceeds derived from such sale. 9. METERING, ANALYSIS, AND ALLOCATION. 9.1 GAS METERING, ANALYSIS AND REPORTS. 9.1.1 Producers shall be responsible for the metering at the Field Delivery Points of all Equity Gas and Injected Liquids, the calibration of such meters and any disputes with respect to such metering. Producers agree to use reasonable efforts to cause Gas meters to be tested on a minimum 45-day frequency for correct calibration and agree to provide, or cause to be provided, to Processor reasonable access to all meters. 9.1.2 Producers shall furnish to Processor such statements as Processor may reasonably require to show the volume in MCF of Equity Gas delivered to Upstream Pipelines during a month at each of Producers' Field Delivery Points no later than the tenth business day of the month immediately following the month in which such Gas is delivered to the Upstream Pipeline. This information may be conveyed by facsimile transmission, with subsequent written confirmation, if necessary to meet the aforesaid deadline. 9.1.3 Producers shall furnish to Processor a representative sample of Equity Gas measured at each Field Delivery Point that identifies GPM for each liquefiable hydrocarbon component in accordance with generally accepted industry standards by no later than the tenth business day of the month immediately following the month in which such Gas is delivered to 19 the Upstream Pipeline. This information may be conveyed by facsimile transmission, with subsequent written confirmation, if necessary to meet the aforementioned deadline. 9.2 LIQUIDS METERING AND ANALYSIS. Processor shall be responsible for the metering and analysis of all liquefiable hydrocarbons extracted from Equity Gas, calibration of such meters and any disputes with respect to such metering. Processor agrees to cause such liquids meters to be tested on a minimum 45-day frequency for correct calibration and agrees to provide, or cause to be provided to Producers, reasonable access to such meters. 9.3 METER FAILURE. In the case of the failure of any measurement meter of a Plant with multiple Gas suppliers, the residue stream attributable to Equity Gas production shall be determined and allotted to Producers according to the provisions of either the applicable agreement controlling the construction and operation of the Plant involved or according to related agreements executed between the owners of the Plant and the owners of any Upstream Pipeline. 10. INDEMNITY. Processor hereby indemnifies and holds Producers harmless against any and all claims, demands, and causes of action of any kind and all losses, damages, costs, and expenses (including court costs and reasonable attorneys' fees) arising from injuries to persons or property attributable to the Equity Gas or Processor's Retrograde, after delivery thereof has been made to Processor at a Plant Delivery Point. Producers hereby indemnify and hold Processor harmless against any and all claims, demands, and causes of action of any kind and all losses, damages, costs, and expenses (including court costs and reasonable attorneys' fees) arising from injuries to persons or property attributable to the Equity Gas or Injected Liquids, including but not limited to Processor's Retrograde, prior to delivery to Processor at the Plant Delivery Point(s) and after Producer's share of the Residue Gas and Products (if applicable under Section 8.2) is delivered to Producer or Producer's designee at the Plant Redelivery Point(s). 11. CURTAILMENT. 11.1 MUTUAL AGREEMENT NOT TO CURTAIL OR WITHHOLD. Producers agree not to unreasonably or arbitrarily withhold production of Equity Gas solely to prejudice the rights granted to Processor hereunder. However, Producers will have no liability to Processor under this Agreement if production is restricted or curtailed for any good faith reason. Likewise, Processor agrees not to arbitrarily withhold Processing services solely to prejudice the rights granted to Producer hereunder. In any such case, Processor shall have no liability to Producer if Processing services are withheld for any good faith reason. 11.2 LIMITED RIGHT TO INTERRUPT PERFORMANCE FOR MAINTENANCE, ETC. Processor and any Producer may, without liability, interrupt its performance hereunder for the purpose of making necessary or desirable inspections, maintenance, repairs, alterations and replacements; and the Processor or Producer requiring such relief shall give to the other reasonable notice of its intention to interrupt its performance hereunder, except in cases of emergency where such notice is impracticable or in cases where the operations of the other Party will not be affected. The 20 Processor or Producer requiring such relief shall endeavor to arrange such interruptions so as to minimize any adverse economic effect on the other Party. 12. FORCE MAJEURE. 12.1 PERFORMANCE EXCUSED. If either Processor or any Producer is rendered unable, wholly or in part by Force Majeure to perform its obligations under this Agreement, other than the obligation to make payments then due or thereafter becoming due as a result of performance of an obligation prior to such Force Majeure, it is agreed that performance of the respective obligations of Processor and such Producer hereunder, so far as they are affected by such Force Majeure, shall be suspended from the inception of any such inability until it is corrected, but for no longer period. The Party claiming such inability shall give notice thereof to the other Party as soon as reasonably practicable after the occurrence of the Force Majeure. The Party claiming such inability shall promptly correct such inability to the extent it may be corrected through the exercise of reasonable diligence. Neither Party shall be liable to the other for any losses or damages, regardless of the nature thereof and howsoever occurring, whether such losses or damages be direct or indirect, immediate or remote, by reason of, caused by, arising out of, or in any way attributable to the suspension or performance of any obligation of either Party to the extent that such suspension occurs because a Party is rendered unable, wholly or in part, by Force Majeure to perform its obligations. 12.2 FORCE MAJEURE DEFINED. For purposes of this Agreement, the term "Force Majeure" shall mean an event, which (i) is not within the reasonable control of the Party claiming suspension, and which by the exercise of reasonable diligence such Party is unable to overcome or (ii) acts of God; strikes, lockouts or other industrial disturbances, acts of the public enemy, wars, blockades, insurrections, civil disturbances and riots, and epidemics; landslides, lightning, earthquakes, fires, storms, hurricanes and threats of hurricanes, floods and washouts; arrests, orders, requests, directives, restraints and requirements of the government and governmental agencies, either federal or state, civil or military; explosions, breakage or accident to machinery, equipment or lines of pipe and outages (shutdowns) of equipment, machinery or lines of pipe. The term "Force Majeure" shall also include any event of force majeure occurring with respect to the facilities or services of either Party's suppliers or customers delivering or receiving any Raw Make, Products, Slug Liquids, Gas, fuel, or other substance necessary to the performance of such Party's obligations, and shall also include curtailment or interruption of deliveries or services by such Third Party suppliers or customers as a result of an event of force majeure. 13. AUDIT RIGHTS. For a period of two years following any statement or payment hereunder or such other period of time, if any, as may be prescribed under applicable COPAS standards, Producers or Processor or any Third Party representative thereof shall have the right, at its expense, upon reasonable notice and at reasonable times, to examine the books and records of the other Party hereto, to the extent reasonably necessary to verify the accuracy of any such statement or payment under this Agreement. In addition, Processor and Producer shall be required to retain all records, contracts and files pertaining to royalty payments for the period of time necessary to 21 comply with contractual or regulatory obligations to lessors, and the same shall be made available upon reasonable notice to the other Parties hereunder. 14. NOTIFICATIONS. 14.1 ANNUAL INFORMATION. On or before September 1 of each year, each Producer shall provide to Processor, without warranty as to accuracy, in reasonable form and substance, Producer's projected volumes and Gas richness (best available composition data) at each existing and projected Field Delivery Point by prospect, Upstream Pipeline and year for the following ten year period. Producers' current "C" volume exploration models or other statistical production models shall be included but may be reported in aggregate. Such provided information shall be referred to collectively as, the "ANNUAL INFORMATION". Producers shall also inform Processor as part of the Annual Information of any plans to purchase or sell Dedicated Lease(s). 14.2 NOTICE OF MATERIAL CHANGES TO ANNUAL INFORMATION. Processor and Producers shall review the Annual Information regularly. Producer shall advise Processor as soon as reasonably practicable of any changes to the Annual Information that could materially impact Processor's plans to Process the projected Equity Gas Volumes. 14.3 NOTICE OF PROPOSED TRANSFERS OF DEDICATED LEASES. In addition to notifying Processor as a part of the Annual Information, Producers shall notify Processor, as soon as reasonably practicable, of, but in any case prior to, any efforts to sell, exchange, or otherwise assign any Dedicated Lease, and Processor shall inform the Producer of its intent to reserve or release such Dedicated Lease from this Agreement. 14.4 NOTICE OF PENDING TRANSPORTATION AGREEMENTS. Each Producer shall notify Processor as soon as reasonably practicable of any ongoing or planned negotiation for the transportation of Equity Gas in an Upstream Pipeline, in order to facilitate Processor's entering into a Gas Processing Agreement for such Equity Gas. Processor and Producer agree to enter into such transportation and Gas Processing contracts contemporaneously, to the extent reasonably practicable and provided that a Producer shall not be obligated to delay entry into any transportation contract when such Producer reasonably believes such delay will result in curtailment of Equity Gas. 14.5 NOTICE OF SCHEDULED PLANT DOWNTIME. Processor agrees to notify Producers as soon as reasonably practicable of any scheduled Plant downtime that could impact Producer's ability to continue to produce Equity Gas. 15. CONFIDENTIALITY. 15.1 GENERAL. Neither Producers nor Processor shall disclose the terms of this Agreement (or the results of any audit pursuant to Article 13) to a Third Party (other than the employees, lenders, counsel, consultants, or accountants of a Processor or a Producer who have agreed to keep such terms confidential) except (i) in order to comply with any applicable law, order, regulation or exchange rule, (ii) in connection with bona fide negotiations with a potential Third Party transferee of a Dedicated Lease or (iii) in connection with bona fide negotiations 22 involving the acquisition or construction of Plant capacity or negotiations on contracts for Third Party Gas Processing agreements.

The Dispute Notice must include (1) a statement of that Party's position and a summary of arguments supporting that position, and (2) the name and title of (a) the executive responsible for administering this Agreement or the matter in Dispute and who will represent that Party and (b) any other person who will accompany the executive in the negotiations under Section 16.3. Within 15 days after delivery of the Dispute Notice, the receiving Parties will submit to the other a written response. The response will include (1) a statement of that Party's position and a summary of arguments supporting that position, and (2) the name and title of (x) 23 the executive who will represent that Party and (y) any other person who will accompany the executive in the negotiations conducted under Section 16.3. 16.3 NEGOTIATION BETWEEN EXECUTIVES. If any Party has given a Dispute Notice under Section 16.2, the Parties will attempt in good faith to resolve the Dispute within 30 days after the receipt of the written response to the Dispute Notice by negotiations between executives identified in Section 16.2. During the 30 days following the receipt of the written response to the Dispute Notice, the executives (identified in Section 16.2) will meet no less than eight hours a day and exhaustively negotiate in good faith and at the expense of all other responsibilities. 16.4 BINDING ARBITRATION. At the end of the 30-day period provided in Section 16.3, if the executives have been unable to resolve the Dispute, and if a disputing Party wishes to submit the Dispute to binding arbitration, the disputing Party shall provide to the other disputing Party three business days' prior written notice of such disputing Party's intention to submit the Dispute to binding arbitration. The other disputing Party shall be entitled to join in the submission of the Dispute to binding arbitration in accordance with the commercial arbitration rules of the AAA (expedited procedures). The AAA shall be instructed to choose an arbitrator who shall have a minimum of 15 years experience in the oil and gas processing industry, or such other experience such that he or she is considered an expert on the business of the Processor. Notice of a disputing Party's submission of the matter for arbitration shall be given to the other Party or Parties within three business days thereafter (the "ARBITRATION NOTICE"). Upon delivery of the Arbitration Notice by the disputing Party, each disputing Party shall have 30 days to provide the arbitrator (and the disputing Party) with a statement of its position (with supporting documentation) regarding the matter or matters in dispute together with its best and final offer for settlement of the Dispute. The failure to provide a statement of position within this period shall constitute a waiver of a disputing Party's right to have such materials considered by the arbitrator. The arbitrator shall consider the statements of position submitted by the disputing Parties and shall, within 30 business days after receipt of such materials, issue his or her decision in writing picking one of the statements of position submitted by the disputing Parties as the position to be adopted to settle the Dispute. All determinations made by the arbitrator shall be final, conclusive and binding on the disputing Parties. Each of the disputing Parties will pay one-half of the fees of the arbitrator and all other arbitration fees and expenses and the fees of their respective arbitrators (if required). 17. TRANSFER AND ASSIGNMENT. 17.1 SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon Producers and Processor. Except for an assignment by Processor in connection with a mortgage of its assets, a disposition of its assets by merger, reorganization or consolidation, sale of all or a substantial part of its assets, or transfer of its assets to an Affiliate, this Agreement shall not be assignable by Processor except with the prior written consent of the affected Producer, which consent shall not be unreasonably withheld or delayed.

Subject to Section 17.4, Producers hereby agree that it is their intent that, to the extent permitted by law, this Agreement constitutes a conveyance by Producers of a portion of their rights as lessee under the Dedicated Leases and that this Agreement shall bind all persons that now or at any time hereafter have any right as lessee or otherwise under any Dedicated Leases, whether by voluntary transfer, involuntary transfer, or otherwise of Leases; provided, however, that nothing in this Section 17.2 or any other provision of this Agreement shall require, or be deemed to require, Processor to pay, or be responsible for, any Royalty Charges, it being the intent of the Parties to this Agreement that Producers shall pay, and be responsible for, any and all Royalty Charges, as provided in Section 8.1. Producers further agree (i) to make any transfer of any Dedicated Lease subject to the terms and conditions of this Agreement and (ii) not to transfer Producer's interest in a Dedicated Lease without first requiring the transferee to execute and deliver to Producer and Processor a Letter of Attornment in the form attached hereto as Exhibit E. 17.3 AFFILIATES OF PRODUCER PARTIES.

As to any Dedicated Leases, or portions thereof, or interests therein that were transferred or assigned by Producers to Third Parties during the period of January 1, 1998 through the Effective Date, inclusive, that were not made subject to the Conveyance as a condition of any such transfer or assignment ("EXCEPTED LEASES"), Processor waives the application of the Conveyance as to the Excepted Leases, and the Parties agree that this Agreement shall not apply to the Excepted Leases unless and until an Excepted Lease is subsequently reacquired by a Producer. 18.
