ARTICLE 4

LIGNITE QUANTITIES

4.1All Requirements. Except as otherwise expressly permitted herein, Buyer shall purchase only Dedicated Lignite as fuel for the Facility during the Term of this Agreement. Subject to the terms of this Agreement, Seller shall sell and deliver to Buyer, and Buyer shall purchase and receive from Seller and pay for, all Dedicated Lignite required by the Facility during the Term of the Agreement. The projected annual Dedicated Lignite requirement for the Facility from the Commercial Operation Date through the Term of this Agreement is 32,881,536 MMBtus (“Base Annual Lignite Quantity”). The Base Annual Lignite Quantity shall be adjusted from time to time in accordance with this Agreement.

4.2Adjustment of Lignite Quantities.

(1) Test Fuel. At least 180 Days prior to the anticipated Commencement Date designated by Buyer pursuant to Section 9.02, Buyer shall provide Seller with its written notice of the total quantity of lignite Buyer reasonably estimates will be required for testing and for Buyer=s stockpile prior to the Commercial Operation Date.

(2) First Twenty-four (24) Months Deliveries. At least 180 Days prior to the anticipated Commercial Operation Date designated by Buyer pursuant to Section 9.02, Buyer shall provide written notice to Seller of the quantity of lignite required, by Month, for the first twenty-four Months after the Commercial Operation Date and for the remainder of the Year following the end of such twenty-four Month period, which quantity, subject to Section 4.02(e), shall be prorated for the number of Months in such remainder of the Year. Such estimate may be revised by Buyer within

seven (7) Days following completion of its acceptance test results analysis with the EPC Contractor.

(3) Annual Projection Notices. On or before June 1 of the Year following the Commercial Operation Date, and on or before June 1 of each Year thereafter, Buyer shall furnish Seller with a non-binding Annual Projection Notice, in the form attached hereto as Exhibit D, showing the projected quantity of Dedicated Lignite required by Month for the following Year.

(4) Consistent Monthly Deliveries. Buyer shall specify in its Annual Projection Notices, to the extent reasonably practical, the projected Monthly quantities of Dedicated Lignite required, recognizing annual Facility preventative maintenance and the seasonal dispatch of energy by the Electric Customer. To assist Seller in scheduling delivery of Dedicated Lignite hereunder, Buyer shall promptly provide Seller with copies of Electric Customer=s “Monthly Dispatch Estimate” as set forth in the PPOA.

(5) Minimum Annual Take Quantity Purchases. Beginning with the Year following the Year in which the first twenty-four Months of deliveries following the Commercial Operation Date ends, and each Year thereafter during the Term of this Agreement, Buyer must take, or pay for, in each Year at least 32,881,536 MMBtus of Dedicated Lignite or Alternate Fuel when delivery of Alternate Fuel is permitted in accordance with the terms of this Agreement (“Minimum Annual Take Quantity”). Such Minimum Annual Take Quantity shall be reduced to the extent (i) Buyer is unable to take Dedicated Lignite due to an approved Scheduled Outage (as defined in the PPOA), (ii) Buyer is unable to use such quantity due to unforseen operational problems at the Facility other than Force Majeure, but in no event shall any such reduction exceed 3,288,154 MMBtus of Dedicated Lignite or Alternate Fuel per Year, (iii) Buyer is unable to use such quantity due to Force Majeure (including Force Majeure of Electric Customer as defined in the PPOA), (iv) Buyer is unable to take lignite because of Seller=s excused or unexcused failure to deliver, (v) Buyer uses gas for combustion stabilization, and (vi) Buyer uses other fuels permitted under Section 4.05(b) (up to 5% of total Btu requirements of the Facility for the Year).

(6) Required Monthly Deliveries. Seller shall be obligated to deliver in any Month up to but not more than 3,300,000 MMBtus of Dedicated Lignite, or Alternate Fuel when delivery of Alternate Fuel is permitted under the terms of this Agreement. At the request of Buyer, Seller shall use

commercially reasonable efforts to provide more than 3,300,000 MMBtus of Dedicated Lignite per Month.

(7) Minimum Take Deficiency. In the event and to the extent Buyer is prevented from taking and using, in any given Year the full required Minimum Annual Take Quantity of Dedicated Lignite or Alternate Fuel scheduled to be taken and used during such Year, net of adjustments for Section 4.02(e) due to the Electric Customer's failure to meet its “Minimum Take Quantity” requirement under the PPOA, then to the extent Buyer is paid a “Minimum Take Deficiency” payment under terms of the PPOA, Buyer shall remit the Fuel Component portion of the Adjusted Base Price hereunder to Seller. In no event shall Buyer be obligated to pay Seller under this Section 4.02(g) until Electric Customer has paid Buyer the Minimum Take Deficiency under the PPOA. Buyer shall aggressively pursue all claims it may have against Electric Customer for any “Minimum Take Deficiency.”

(8) Alternate Fuel. Subject to the provisions of Section 4.05(a), as long as the total cost to Buyer of producing electricity utilizing Alternate Fuel is no greater than the total cost to Buyer of producing electricity utilizing Dedicated Lignite of the specifications in Article 6 and such utilization does not violate or erode emission or utilization capacity of any permits, regulations or approvals with which Buyer is required to comply, Buyer agrees to accommodate Seller to the extent possible by accepting deliveries of Alternate Fuel at the Point of Delivery by whatever mode of transportation is mutually acceptable to the Parties. If, and to the extent, Alternate Fuel is delivered as provided in this Section 4.02(h), such quantities shall be credited against the Parties' obligations regarding Dedicated Lignite or Alternate Fuel to be delivered during such period.

(9) Credits. (i) Buyer shall receive a lignite quantity credit (on a MMBtus basis) (the “Minimum Annual Take Quantity Credit”) for all Dedicated Lignite or Alternate Fuel quantities purchased by Buyer in any Year in excess of 36,169,689 MMBtus. Such Minimum Annual Take Quantity Credit may be used by Buyer and applied against deliveries of Dedicated Lignite or Alternate Fuel only in the following two (2) Years and only to the extent that Buyer purchases quantities less than the Minimum Annual Take Quantity for such Year(s) (as adjusted pursuant to Section 4.02(e)). (ii) If in any Year Buyer fails to take the Minimum Annual Take Quantity for such Year (as adjusted pursuant to Section 4.02(e)), Buyer shall receive a Minimum Annual Take Quantity Credit (on a MMBtus basis) for the quantity of Dedicated Lignite paid for but not taken by Buyer which is less than such Minimum Annual Take Quantity. Such credit may be used by Buyer and applied against deliveries of Dedicated Lignite or Alternate Fuel only in the two (2) Years following the Year for which the credit is

received and only to the extent such deliveries are in excess of 32,881,536 MMBtus in the Year such credit is taken.

4.3Revision of Annual Lignite Quantity.

(1) The quantities of Dedicated Lignite set forth in Exhibit C are based upon an anticipated Commencement Date of July 1, 2000. In the event for any reason the actual Commencement Date differs from such anticipated date, Seller and Buyer shall meet as soon as practicable to mutually agree upon revisions to Exhibit C to reflect a pro rata revision in the Annual Lignite Quantity for the first and last Years.

(2) If Electric Customer notifies Buyer of a revision in its expected dispatch of the Facility for any Year, Buyer shall be entitled and required to revise the Annual Projection Notice for such Year (or partial Year).

4.4Stockpile Lignite. Seller shall maintain a stockpile of run-of-mine Dedicated Lignite consistent with good mining practices for a mine-mouth lignite facility serving the independent power industry sufficient to enable Seller to meet its obligations to deliver Dedicated Lignite to the Facility under this Agreement. Buyer shall maintain a stockpile of Dedicated Lignite at the Facility of such quantity that is consistent with good utility practice (including independent power producers) for mine-mouth generating facilities. Seller=s stockpile of Dedicated Lignite will be sufficient to enable Seller to meet its obligations to make deliveries at all times of the Year taking into account the effects of normal rainfall and temperature upon the Mine operations and seasonal changes such that rainfall and temperature impacts on Mine operations will not prevent Seller from meeting its delivery obligations.

The Parties acknowledge that these stockpiles will fluctuate in size because different quantities of Dedicated Lignite are required on different Days as well as for other reasons.

4.5Alternate Fuel Sources.

(1) Seller and Buyer acknowledge that the Facility is being constructed to utilize Dedicated Lignite as its primary fuel. If for any reason, other than Force Majeure, Seller cannot supply sufficient Dedicated Lignite to meet the requirements of this Agreement, Seller shall be responsible for the prompt supply of the necessary Alternate Fuel to enable Buyer to continue to operate the Facility without interruption. Seller shall supply such Alternate Fuel at a cost to Buyer which is the then applicable Billing Price determined in accordance with Article 7. Seller shall have the right, upon 72 hours prior notice to Buyer, to supply Alternate Fuel to Buyer from any source so long as such fuel meets the requirements of Section 4.02(h).

(2) Buyer shall have the right to procure Mississippi wood or wood-product residue to supply up to, but not more than, five percent (5%) of the total Btu requirements of the Facility for any given Year. If Buyer is asked by the Electric Customer or the Choctaw County economic development officials to burn tires or other suitable waste products, other than Mississippi wood product residue, at its Facility, Buyer and Seller shall renegotiate in good faith the terms of this Agreement to allow Buyer to consume such waste products as fuel in reasonable levels in lieu of Dedicated Lignite. Provided, however, in no event shall Buyer burn Mississippi wood, wood product residue, tires, or other waste product fuels to supply more than five percent (5%) of the total Btu requirements of the Facility in any given Year.

4.6Sale to Others. Seller shall have the right to sell outside this Agreement lignite from the Lignite Property, provided that Seller can reasonably demonstrate to Buyer that the exercise of such right does not impair Seller's ability to perform its obligations under this Agreement.

ARTICLE 5

MEASUREMENT OF LIGNITE QUANTITIES,

SCALES, RIGHT OF INSPECTION, AND PARTIES' ACCESS

5.1Measurement of Lignite Quantities. The lignite unloading and handling facilities to be located at the Point of Delivery, including the truck dump, shall be designed, constructed, owned, maintained and operated by Buyer at its sole risk and expense. Buyer shall determine the quantities of lignite delivered by Seller by means of a belt scale (the “Pay Scale”) to be designed, constructed, owned, maintained and operated by Buyer at its sole risk and expense, except for calibration as noted below, in accordance with standards recommended by the equipment manufacturer, and agreed to by the Parties, as may be amended from time to time. If such standards are discontinued, the Parties shall continue to use the last effective standards and shall use reasonable efforts to find and agree to replacement standards. If the Parties are unable to agree, the matter shall be submitted to Arbitration. The last effective standards shall remain effective until the matter is resolved either by agreement or Arbitration. Seller shall have the right to review and comment on the designs of the unloading and handling facilities, and the Parties agree to use reasonable efforts to coordinate design and equipment selection for lignite delivery unloading and handling. Seller also shall have the right to install a check scale on the conveyor belts at Seller's sole risk and expense (the “Check Scale”). Seller shall be obligated to operate, maintain and calibrate the Check Scale in accordance with standards recommended by the equipment manufacturer and agreed to by the Parties.

5.2Scales, Right of Inspection and Accuracies. Buyer and Seller shall arrange for an appropriately certified independent third party to calibrate the Pay and Check Scales, respectively, at least twice per year. Both Parties may, by mutual consent, waive third-party calibration of the scales and perform such calibrations jointly. In such event, both Parties agree

to be bound by the result of such joint calibration until the next semiannual calibration of the scales takes place. The cost of calibration of the Pay Scale and Check Scale, however accomplished, shall be shared equally by Buyer and Seller. Each Party shall have the right, at its own expense, to inspect the other Party=s lignite sampling, weighing and the laboratory testing facilities, and to observe the other Party=s sampling, weighing and analytical procedures. Either Party may request a calibration of the Pay Scale or Check Scales at any time. If the scales are found to be within manufacturer accuracy limits, the requesting Party will pay for the test; otherwise, the other Party shall pay for the test. If the scales are found to be in error outside the manufacturer=s allowable tolerance by more than one-half percent (0.5%) of the base quantity being measured, the weights and corresponding invoices and payments shall be adjusted accordingly from the point of error, or if such point cannot be agreed upon between the Parties, such adjustment shall be for one-half (2) of the tonnage of Dedicated Lignite or Alternate Fuel delivered since the last determination of accuracy.

5.3Parties= Access. Each Party shall have the right from time to time during the Term of this Agreement to arrange for its employees, geologists, lenders, consultants and engineers and similar representatives of Electric Customer to visit the Mine and the Facility, on reasonable prior notice to the other Party and so long as it does not unreasonably interfere with the other Party=s operations.

ARTICLE 6

FUEL QUALITY

6.1Quality. The Dedicated Lignite or Alternate Fuel to be supplied hereunder shall be substantially free from impurities such as, but not limited to, bone, slate, earth, rock, pyrite, wood, tramp metal and mine debris. In addition, the Dedicated Lignite or Alternate Fuel shall not be contaminated with any Hazardous Materials. Seller agrees that the weighted average Aas received@ quality of Dedicated Lignite or Alternate Fuel supplied hereunder over the term of this Agreement will be as follows:

CharacteristicsSpecifications

Moisture, % by weight 41.75%

Ash, % by weight 14.64%

Sulfur, % by weight 0.58%

Calorific Value, Btu/lb (HHV) 5294 Btu/lb.

If the weighted average "as received" quality of Dedicated Lignite or Alternate Fuel delivered to Buyer by Seller over the term of this Agreement does not meet the above specifications, Seller shall not be deemed to be in default hereunder except as provided in Section 6.06 below, and Buyer shall not be entitled to damages or compensation of any kind, other than the amounts and remedies provided in this Article 6.

6.2Sampling and Analysis. All sampling and analysis will be performed in accordance with methods approved by ASTM or such alternate written standards and procedures mutually agreed to by the Parties. The quality of Dedicated Lignite or Alternate Fuel delivered to Buyer by Seller shall be determined by analysis of samples taken daily at the Facility by the Buyer at a point mutually agreed to by the Parties. Buyer will take samples by means of an automatic mechanical sampling system to be owned, operated and maintained by Buyer. Buyer shall cause the samples to be transported to a laboratory of Buyer=s choice. Buyer=s laboratory shall participate in round robin testing to verify the accuracy of sample preparation and analysis. If the round robin testing establishes that the laboratory=s sample preparation and analysis is inaccurate, the Parties will agree upon a new laboratory. Each sample shall be processed, split into three equal parts and placed in suitable airtight containers by Buyer or the laboratory. Part one of each sample shall be analyzed by the laboratory at Buyer=s expense. Part two of each sample shall be properly identified and stored at the laboratory for a period of not less than fifteen (15) Business Days for Seller to analyze at its own expense if it so desires. Part three of each sample shall be properly identified and stored for a period of not less than thirty (30) Business Days. The cost of analysis of part three of the sample, if required, shall be borne equally by Buyer and Seller. For deliveries for which a sample is not available or for which a sample is agreed by Buyer and Seller to be incorrect, the weighted average of the immediately preceding three (3) Days= sample analyses which are available shall be utilized.

6.3Analytical Results. The results of the analyses performed by the laboratory on part one of the samples shall be binding on the Parties and shall be deemed to represent the quality of the Dedicated Lignite or Alternate Fuel delivered hereunder unless one Party notifies the other of a dispute concerning such analysis within the fifteen (15) Business Day period specified in Section 6.02. If the analysis of part one is disputed and the analyses of parts one and two differ by more than a maximum tolerance range as shall be agreed to by the Parties (the “Maximum Allowable Tolerance”), then part three of such sample shall be analyzed by a commercial testing laboratory mutually chosen and using mutually accepted procedures. When all three parts of a sample are analyzed, the average of the two closest sample results will be used to represent the quality of the lignite delivered on the Day such samples were taken; provided, however, that if the two closest sample results differ by more than the Maximum Allowable Tolerance, then the weighted average of the immediately preceding three (3) Days= sample analyses which are available shall be deemed to be the quality of the Dedicated Lignite or Alternate Fuel under consideration. The Billing Price for the Dedicated Lignite or Alternate Fuel represented by such samples shall be adjusted on the next invoice submitted by Seller as specified in Section 8.02

6.4Notice of Sampling Results. Within the first five (5) Business Days after each daily sample is taken, Buyer shall furnish Seller with a written notice depicting the laboratory results for part one of each sample. Reasons for Rejectable Fuel, as specified in Section 6.06, shall be stated in the notice. If Seller elects to analyze part two of a sample, Seller shall provide written notification to Buyer within the fifteen (15) Business Day period specified in Section 6.02. In addition, Seller shall deliver the results of such analysis to Buyer within five (5) Business Days of receiving such results.

6.5Periodic Lignite Specifications and Price Adjustment. If the quality of Dedicated Lignite or Alternate Fuel delivered by Seller to Buyer pursuant to this Agreement deviates from the quality specifications listed in Section 6.01 on an “as-received” daily basis, but falls above the minimum and below the maximum specifications listed in this Section 6.05, then for such Dedicated Lignite or Alternate Fuel there shall be a price adjustment for that Day=s delivery:

Specifications

CharacteristicsMinimumMaximum

Calorific Value, Btu/lb (HHV)4,4008,000

Moisture, % by weight2049.4

Ash, % by weight5.023.5

Sulfur, % by weight0.151.23

The methodology for such adjustment is set forth in Exhibit J, Quality and Property Price Adjustment.

6.6Rejectable Fuel. If the analysis performed pursuant to Section 6.02 and Section 6.03 reveals that the quality of Dedicated Lignite or Alternate Fuel delivered during any Day is below any minimum or above any maximum specification listed in Section 6.05, then such Dedicated Lignite or Alternate Fuel shall be deemed to be “Rejectable Fuel.” Once delivered, any Rejectable Fuel shall be the property of Buyer. For any Rejectable Fuel consumed by the Facility, Buyer shall be entitled to deduct the charges for that quantity of Rejectable Fuel from Seller=s invoices. Notwithstanding the above, all deliveries of Rejectable Fuel count towards Buyer=s Minimum Annual Take Quantity. If for any cumulative period of 90 Days out of any twelve-Month period the cumulative average for all Dedicated Lignite or Alternative Fuel delivered would be Rejectable Fuel hereunder, an Event of Default by Seller shall have occurred.

6.7Secondary Fuel Quality Impact. If the quality of Dedicated Lignite or Alternate Fuel delivered by Seller is not within the ranges specified below for the listed characteristics, the Parties shall work together to determine how to ensure that the Dedicated Lignite or Alternate Fuel delivered in the future shall be within such ranges. If the Buyer is fined or penalized by governmental authorities for emission permit violations caused by the Dedicated Lignite or Alternate Fuel delivered by Seller not being within the specified ranges, then Seller shall reimburse Buyer for such fines or penalties.

6.08 Testing of Sample System. During the first twelve (12) Months after the Commercial Operation Date, Buyer shall perform one (1) bias test of the sampling system. Thereafter, commencing from the date of such bias test, Buyer shall perform additional bias tests of the sampling system at least once every thirty (30) Months or as recommended by the manufacturer=s standards, unless Buyer and Seller mutually agree otherwise. Seller shall have the right to have a representative present at any and all times to observe the sampling. Seller shall also have the right to request a bias test of the sampling system if Seller questions the accuracy of said system. Seller shall pay all costs of any such challenge bias test unless the sampling system is found to be in error in excess of that specified by the equipment manufacturer, in which case Buyer shall reimburse Seller for the costs of such test. Any errors found in the sampling system by the bias test shall be immediately corrected.

ARTICLE 7

PRICE

7.1Base Price. The Base Price for all Dedicated Lignite or Alternate Fuel delivered under this Agreement shall be [* * *] per MMBtus F.O.B. Point of Delivery. The Base Price consists of eight (8) indexed components, a power cost component, a pass-through component, a royalty component and a fixed component as set forth in Exhibit E.

7.2Billing Price. The Billing Price for all Dedicated Lignite or Alternate Fuel delivered under this Agreement shall be determined by taking the Base Price, adjusting that Base Price in accordance with the formula set forth in Exhibit E to determine the Adjusted Base Price, and then applying any quality adjustments pursuant to Article 6.

7.3Modification of Index. Subject to Section 7.04, should any of the indices used for escalation adjustment as set forth in Exhibit E be revised by the agency publishing such index, then invoices prepared subsequent to the revision shall use the revised index. If the numerical value of any index is changed by the issuing agency subsequent to the initial publication, then any subsequent use of this index in making calculations under this Exhibit will be made using the most recent numerical value of that index. If the referenced index is no longer published, the index designated by the agency responsible for publishing said index as the replacement will be used. If no replacement index is specified, a new index which most accurately reflects changes for the applicable cost components shall be substituted by mutual agreement of the Parties. In the event the Parties fail to agree, such matter shall be submitted to Arbitration.While the Arbitration concerning the appropriate substitute index is pending, the values contained in the relevant index prior to its discontinuance shall be used subject to true-up at the conclusion of the Arbitration.

* * * Confidential Treatment Requested

7.4Parallel Index Changes and Pass Through Costs under PPOA. Seller and Buyer acknowledge that as to the following rights of Seller under this Agreement, Buyer has similar rights against Electric Customer under the PPOA:

(1) Changes to the indices used for escalation and adjustments pursuant to Section 7.03; and

(2) Seller's right to pass through to Buyer as a component of the Billing Price the cost of certain taxes, fees and charges as set forth in Sections 20.01 and 20.04 and Exhibit E.

If Seller claims that any index should be changed or that any tax, fee or charge should be passed through to Buyer, Buyer shall make and diligently pursue negotiations with Electric Customer for the same index change or pass-through under the PPOA, and Seller shall cooperate with, support and assist Buyer in Buyer's efforts to obtain Electric Customer's consent to the same index change or pass-through of tax, fee or charge under the PPOA. Buyer agrees to (1) keep Seller fully informed of such efforts, (2) provide Seller with copies of all documents or portions thereof received by Buyer from Electric Customer pertinent to such index changes, and (3) permit Seller to participate in all meetings and discussions with Electric Customer regarding such efforts. If Buyer=s negotiations with Electric Customer are unsuccessful, then the dispute shall be settled pursuant to the Three-Way Arbitration Agreement.

The foregoing notwithstanding, no change to indices pursuant to this Section 7.04 shall be made unless Electric Customer has agreed to parallel changes in the PPOA or unless a change to indices is required to comply with an Arbitration award or court order.

ARTICLE 8

PAYMENT

8.1Agreement to Pay. Except as otherwise specifically provided in this Agreement, Buyer shall pay to Seller the Billing Price for Dedicated Lignite or Alternate Fuel, F.O.B. the Point of Delivery, on an Aas-received@ basis.

8.2Method of Billing and Payment. Seller shall invoice Buyer on or after the tenth (10^th) Day of each Month for Dedicated Lignite or Alternate Fuel delivered during the immediately preceding Month. If there is insufficient information regarding quality, Seller may render an invoice using an estimate of quality with appropriate adjustments to be made as soon as sufficient information is available. Buyer will make payment therefor, by bank wire transfer of funds to a bank account to be designated by Seller on or before the twenty-fifth (25^th) Day after receipt of each invoice.

8.3Minimum Payments. If in any Year Buyer fails to purchase the Minimum Annual Take Quantity and such failure to take is not excused pursuant to the terms of this Agreement, then Seller's last invoice for such Year shall include, in addition to the charge for the amount of Dedicated Lignite or Alternate Fuel actually delivered and taken, the charge for the amount of Dedicated Lignite that Buyer must pay for though not taken pursuant to Section 4.02(e) or (g), as the case may be. The charge for Dedicated Lignite not taken shall be based upon the Adjusted Base Price in effect at the time the invoice is sent with no adjustment for quality.

8.4Disputed Invoices. If Buyer disagrees with the amount of any invoice for any reason, Buyer shall promptly notify Seller in writing of such disagreement so that the difference may be resolved before the due date of payment of the invoice. If Buyer fails to give such notification, or if Buyer and Seller resolve such disagreement before the due date, such invoice shall be paid in full according to its terms or as agreed to by Buyer and Seller on the due date. If Buyer does give such notification and if Buyer and Seller do not resolve such disagreement before the due date, the portions of the invoice not in dispute shall be paid in accordance with the terms of Section 8.02 hereof on the due date, with the remaining portion of the disputed invoice to be withheld subject to adjustment upon final resolution of the disagreement, with any adjustment due Seller to bear Interest for each Day commencing on the due date and continuing until paid. Notwithstanding the above, either Party hereto shall be entitled to a credit or refund for erroneous payments made, whether such payments were made with or without notice of disagreement, provided that written claim for such credit or refund has been made within twenty-four (24) Months following the date on which the invoice was rendered. Such credit or refund shall bear Interest from the date the erroneous payment was made until the credit is taken or until the refund is paid. Neither Party hereto shall be entitled to take such credit or receive such refund until such other Party hereto shall have agreed to the same or until final resolution of the disagreement relating to any disputed credit or refund.

8.5Failure to Pay Undisputed Invoices. If Buyer fails to pay any undisputed invoice or undisputed part thereof rendered by Seller, then Buyer shall pay to Seller Interest on the unpaid balance of such invoice, calculated from the due date until the date of payment by the Buyer.

8.06Books and Records. Seller shall maintain, for a period of at least five (5) Years, books and records of all payments, price revisions, adjustments, credits, debits and all other data relating to its operations hereunder in order that the provisions of this Agreement and, more specifically, the provisions of the attached Exhibit E can be adequately administered.

8.07Inspection of Price Records. At all reasonable times, upon written notice from Buyer, Seller shall make such records and books of accounts as are needed to verify compliance with the pricing terms of this Agreement available for inspection and audit. Such an audit may be conducted, at Buyer's option, by (a) Buyer's or Electric Customer's internal audit staff, or (b) a firm of certified public accountants to be selected by Buyer or Electric Customer. Buyer's or Electric Customer's auditors shall treat as confidential any and all proprietary information (including auditors' work papers) of Seller, furnished to or examined by them in connection with audit work performed for Buyer. Electric Customer's rights hereunder shall extend only to

inspection and audits of pass-through pricing items and taxes that are subject to audit under the PPOA or under federal law.

ARTICLE 9

NOTICES TO PROCEED

9.01Duty to Keep Informed. During the permitting, development and construction of the Facility and the Mine, both Parties agree to keep the other informed, in writing, on a timely basis on all aspects of development, permitting (including the supply of samples or data) and construction, and any changes to any permitting, development or construction schedules shown in Exhibit I, Permitting and Construction Schedule.

9.02Buyer Notices. If Buyer pre-releases the EPC Contractor to begin detailed design work for the Facility, Buyer shall so notify Seller. At such time as Buyer issues the final release for the EPC Contractor to begin work at the Facility site, Buyer shall, by issuance of a Facility Notice to Proceed, notify Seller and authorize Seller to proceed with construction of the Mine as set forth in Section 3.02, in accordance with the terms and conditions of this Agreement. The Facility Notice to Proceed shall include confirmation of the anticipated Commencement Date of July 1, 2000 or notify Seller of a different anticipated Commencement Date and the anticipated Commercial Operation Date. Except as set forth in Section 3.06, until such time as Buyer issues such Facility Notice to Proceed to Seller and notifies Seller of the anticipated Commencement Date and the anticipated Commercial Operation Date, Buyer shall have no financial obligation to Seller, and Seller shall have no obligation to Buyer, for construction of the Mine other than for permitting and preconstruction development purposes. Provided that Buyer issues the Facility Notice to Proceed to Seller simultaneously with Buyer's issuance of a final release for the EPC Contractor to begin work at the site in accordance with the PPOA and at the same time notifies Seller of the anticipated Commencement Date and the anticipated Commercial Operation Date, Seller shall timely proceed with construction of the Mine, and Seller will be ready to commence lignite delivery in accordance with this Agreement.

9.03Commencement Date Notice. Three Months prior to the anticipated Commencement Date, Buyer shall confirm or revise the date of the anticipated Commencement Date and the anticipated Commercial Operations Date contained in the Facility Notice to Proceed and the lignite quantity required for testing. The anticipated Commencement Date may be moved to an earlier date than that provided in the Facility Notice to Proceed only if it is mutually agreeable. Subject to the last sentence of Section 9.02, Seller agrees to be ready to deliver lignite in sufficient quantities to the Facility, and Buyer agrees to be ready to accept quantities on the Commencement Date for the Facility. Buyer and Seller shall keep each other informed of progress on construction of the Facility and the Mine on a Monthly basis. The Parties acknowledge that the actual date for commencement of lignite deliveries may change as construction of the Facility proceeds. The rights and obligations of the Parties as to any such delays, however, shall be as set forth in Article 10.

9.04Copies of Permits. Buyer shall provide Seller with copies of all permits and approvals for the Facility as they are obtained. Seller shall give Buyer prompt written notice upon receipt by Seller of all permits and approvals required for the construction, development and initial operation of the Mine and shall provide Buyer with copies of permits and approvals as they are obtained.

ARTICLE 10

DELAY AND SHUTDOWN

10.01Delay of Commencement Date. To the extent that there is an unexcused delay of Commencement Date beyond the specified anticipated Commencement Date in the Notice to Proceed in Section 9.02 resulting from actions or inactions of Buyer and/or any contractor of Buyer (other than Electric Customer or Seller), and if such delay exceeds two Months, Buyer shall pay to Seller as liquidated damages $42,500 per Day for each Day that the delay continues beyond two Months until the actual Commencement Date.

10.02Delay of Commercial Operation Date and Buyer Shutdown Option.

(a) To the extent that a delay of Commercial Operation Date as specified by Buyer in the notice referred to in Section 9.02 results from actions or inactions of Electric Customer and as a result of such delay Electric Customer pays Buyer the capacity payment as provided in Section 4.3(a) of the PPOA, Buyer shall pass through to Seller the "Fixed Component" portion of the Base Price as set forth in Exhibit E. To the extent that an unexcused delay of the Commercial Operation Date results from actions or inactions of Buyer and/or any contractor of Buyer (other than Electric Customer or Seller), Buyer shall pay to Seller as liquidated damages the amount of $56,200 per Day for each Day that the delay continues.

(b) Seller acknowledges that from time to time during the first twenty-four (24) Months following the Commercial Operation Date, Buyer may desire to temporarily shut down and suspend, either partially or wholly, operation of the Facility because of technological or operational problems preventing the Facility from performing according to specifications. As a result of such interruptions, Buyer may fail to take the full quantity of Dedicated Lignite requested by Buyer pursuant to Section 4.02(b). Nevertheless, to compensate Seller for having constructed the Mine in a timely fashion to be ready to deliver such quantity during the first twenty-four (24) Months following the Commercial Operation Date, and notwithstanding that Buyer shall have no Minimum Annual Take Quantity obligation during such period, Seller and Buyer agree that, if during either the first half or the second half of the first twenty-four (24) Month period following the Commercial Operation Date Buyer takes and pays for a quantity of Dedicated Lignite or Alternate Fuel having a Billing Price less than $20,232,000, Buyer shall pay Seller as liquidated damages the

difference between $20,232,000 and the amount of money paid for Dedicated Lignite or Alternate Fuel actually taken during such twelve (12) Month period.

10.03Seller Delay. To the extent that Seller's unexcused failure to deliver appropriate quantities of lignite of appropriate quality delays the testing of the Facility, then Seller shall be liable to Buyer for damages in an amount equal to $95,000 per Day plus Contractor's Delay Costs pursuant to the EPC Contract for the period of the delay. If such delay results in a delay of the Commercial Operation Date, Seller shall be liable to Buyer for damages in an amount equal to (a) the damages Buyer pays to Electric Customer resulting from such delay, plus Buyer's capacity payments that Buyer would have received from Electric Customer but for Seller's non-delivery (less expenses Buyer would have incurred to operate the Facility), or (b) at Seller's option, the cost to Buyer of replacement fuel sufficient to meet Electric Customer's dispatch of the Facility in excess of the price of Dedicated Lignite under this Agreement.

ARTICLE 12

FORCE MAJEURE

12.01Events of Force Majeure. The term “Force Majeure” as used in this Agreement shall mean any and all events or causes, whether foreseen or unforeseen, which are beyond the reasonable control and without the fault or negligence of the Party failing to perform and which prevent the mining, producing, processing, transporting and/or delivering of Dedicated Lignite by Seller or the receiving, accepting, and/or utilizing Dedicated Lignite by Buyer at the Facility, or otherwise prevent Seller or Buyer from performing its obligations under this Agreement. Events of Force Majeure include, but are not limited to, acts of God, lightning, storms, sabotage, riot, insurrection, war, strike, labor disputes or labor slowdowns closure of all or part of the Mine or the Facility because of imminent danger to the Mine or the Facility, material breakdowns or material damage to the Mine or the Facility or equipment, fire or accident or explosion or casualty where such fire or accident or explosion or casualty is beyond the reasonable control of the Party claiming Force Majeure, and acts of civil governmental authority (including TVA with regard to its board's record of decision of Environmental Acceptability of the Facility, as defined in the PPOA Articles 1 and 2, or any other action of TVA when acting in its governmental agency EIS review capacity), including without limitation compliance in good faith with any regulation (or change in interpretation or enforcement of a regulation), direction or order (whether valid or later found to be invalid) made by or on behalf of governmental authorities after the Effective Date of this Agreement, which compliance materially and adversely affects the Mine or the Facility.

Notwithstanding the foregoing, “Force Majeure” shall not include (a) a decrease in demand for electric power from the Facility caused by changes in market conditions or economic climate that decreases the demand by the Facility for lignite below the amounts required in Section 4.02 of this Agreement, (b) the enactment, adoption, promulgation or imposition of any legal requirement that restricts or prevents the utilization or burning of Dedicated Lignite supplied by Seller under this Agreement at the Facility, unless such legal requirement completely prevents Buyer from utilizing or burning any such Dedicated Lignite at the Facility under any circumstances or (c) weather conditions other than severe weather conditions.

12.02Suspension of Obligations. If, because of Force Majeure, either Party hereto is unable to carry out any of its obligations under this Agreement (other than the obligation of a Party to pay money when due in connection with the performance of this Agreement), and if such Party shall promptly give to the other Party written notice of such Force Majeure, then the obligation of the Party giving such notice shall be suspended to the extent made necessary by such Force Majeure and during its continuance, provided, however, that the Party giving such notice shall use its best efforts to eliminate such Force Majeure insofar as possible with a minimum of delay, except such Party shall not be obligated to settle strikes, labor disputes or labor slowdowns. Any deficiencies in (a) deliveries of Dedicated Lignite hereunder by Seller caused by Force Majeure, or (b) deficiencies in the receipt of Dedicated Lignite by Buyer hereunder caused by Force Majeure, shall not be made up except by mutual consent. In the event Force Majeure causes only a partial reduction in the total quantity of Dedicated Lignite Seller can deliver or Buyer can utilize, Seller shall deliver to Buyer all of the Dedicated Lignite within the Annual Projection Notice which can be produced from the Mine, and Buyer shall receive all of such Dedicated Lignite which can be accepted by Buyer during the continuance of such partial reduction.

12.03Suspension of Lignite Deliveries. Either Party hereto shall have the right to elect to suspend the purchase or sale of Dedicated Lignite, as the case may be, for the period of time during which such Force Majeure may exist and to the extent of the quantity of Dedicated Lignite affected by Force Majeure. During such period of Force Majeure, Seller shall have the right but not the obligation to supply Alternate Fuel to Buyer in quantities sufficient to fulfill the Facility's MMBtu requirements at no additional cost to Buyer. If Seller elects not to supply such Alternate Fuel, then Buyer, if it so elects, shall have the right during such period to purchase alternate fuel from other sources in quantities sufficient to meet the Facility's fuel requirements.

12.04Time Limit for Claiming Force Majeure. A Party seeking to claim that it has experienced a Force Majeure must so notify the other Party in accordance with Section 12.02 hereof within forty-eight (48) hours of its discovery of the Force Majeure. If a Party fails to provide notice of a Force Majeure within forty-eight (48) hours of its discovery but subsequently provides notice of the Force Majeure, such Party=s obligations shall be suspended as of the date of such late notice but not for any period prior to the delivery of such late notice.

12.05Long Term Force Majeure. In the event a Force Majeure occurs and continues for an uninterrupted period of one (1) Year, either Seller or Buyer may terminate this Agreement by giving written notice to the other Party within ninety (90) Days after the expiration of such one (1) Year period; provided, however, in the event a Party can reasonably demonstrate during such one (1) Year period that such Force Majeure can be cured within two (2) Years from the commencement of the Force Majeure, the other Party shall be entitled to terminate this Agreement only if such Force Majeure continues uninterrupted for two (2) Years, otherwise this Agreement shall continue in full force and effect for the full remaining Term thereof.

ARTICLE 13

13.01Events of Default. The occurrence of any one of the following shall constitute an Event of Default under this Agreement:

(a) the failure in any material respect of any Party to perform any material covenant, condition or obligation under this Agreement (including but not limited to Seller's delivery of Dedicated Lignite or Alternate Fuel),

(b) the breach in any material respect by a Party of a material warranty or representation made by that Party in this Agreement,

(c) the insolvency of a Party (other than as a result of the other Party's withholding of payment of disputed charges),

(e) the appointment of a receiver or trustee for the benefit of creditors of a Party, or

(f) the execution by a Party of an assignment for the benefit of creditors, or

(g)an Event of Default as described in Section 6.06.

13.02Procedure for Notifying a Party of Default.

(a) Upon the occurrence of any Event of Default under Section 13.01 (a) or (b), the non-defaulting Party shall notify the defaulting Party in writing of the occurrence of such Event of Default. Within not more than five (5) Days after such Notice, the defaulting Party shall submit an action plan to cure such Event of Default. The defaulting Party shall have sixty (60) Days from such notice to cure such Event of Default. If such Event of Default cannot be cured with reasonable efforts within such sixty (60) Day period and the defaulting Party is diligently pursuing cure through the action plan, the defaulting Party shall be permitted an additional reasonable period of time not to exceed more than one hundred eighty (180) Days to cure such Event of Default and the non-defaulting Party shall not terminate this Agreement during such additional time period.

(b) In the event the non-defaulting Party gives notice of an Event of Default occurring under Section 13.01 (a) or (b), and the defaulting Party fails to cure such default within the foregoing sixty (60) Day period (or such longer period as may be approved by the non-defaulting Party, which

approval shall not be unreasonably withheld), then the non-defaulting Party shall have the right to terminate this Agreement by giving the defaulting Party notice of such termination. This Agreement shall terminate thirty (30) Days after receipt by the defaulting Party of the notice of termination. In the event of such termination, the non-defaulting Party will have available to it all remedies contained in this Agreement and all remedies allowed by law; provided, however, that the forum for resolution of disputes arising out of this Agreement shall be Arbitration conducted pursuant to the provisions of Article 19. Notwithstanding the foregoing, if the defaulting Party gives the non-defaulting Party notice that the defaulting Party disputes that such Event of Default has occurred and is continuing, and that the defaulting Party is submitting the matter to Arbitration in accordance with Article 18 of this Agreement, then the defaulting Party shall not be deemed in default under this Agreement and the non-defaulting Party shall not have the right to terminate this Agreement until the matter has been so finally determined by Arbitration.

(c) If there is an Event of Default under Section 13.01(c) through (g), upon giving notice to the defaulting Party, the non-defaulting Party may terminate this Agreement effective upon proper delivery of such notice under the terms of this Agreement. Except as provided in Section 13.04(d), in the event of such termination, the non-defaulting Party will have available to it all remedies contained in this Agreement and all remedies allowed by law; provided, however, that the forum for resolution of disputes arising out of this Agreement shall be Arbitration conducted pursuant to the provisions of Article 19.

13.03Limitations on Right of Termination. Notwithstanding anything to the contrary contained in this Article 13, neither Party shall have the right to terminate this Agreement on the grounds of a default if such default has occurred and is continuing solely as a result of:

(a) any material failure by the Party desiring to terminate, or any material failure by an agent of or contractor (other than Buyer or Seller) to such Party to carry out such Party's material obligations under this Agreement;

(b)any failure to pay any sum due pursuant to this Agreement;

(c) a reasonable difference with governmental authorities as to the interpretation of applicable governmental laws, rules or regulations or impossibility of compliance therewith, so long as the affected Party is diligently pursuing a resolution of the matter with the governmental authorities.

13.04Step-In Rights.

(a)Step-In Triggering Events. If:

(1) this Agreement is terminated by Buyer pursuant to Section 13.02(b); or

(2) there is an Event of Default by Seller as described in Section 13.01(c), (d), (e), (f) or (g) and Seller is unable to substantially perform its obligation to deliver Dedicated Lignite or Alternate Fuel,

then Buyer shall have the right, but not the obligation, to give Seller written notice thereof (the AStep-In Notice@) stating that Buyer desires to exercise its rights under this Section 13.04 ("Step-In Rights").

(b) Step-In. In the event the Step-In Notice is given by Buyer pursuant to subsection 13.04(a)(1) or (2) above, Buyer at its option shall have the right to succeed to all right, title, and interest of Seller in and to the Dedicated Lignite and all mining equipment, permits, rights and other assets for the Mine, and, if elected by Buyer in its Step-In Notice, that portion of the Mine which is necessary for producing the Dedicated Lignite. For all mining equipment, permits, rights, or other assets to which Buyer shall take title pursuant to a Step-In Notice pursuant to subsection 13.04(a)(1) or (2) above, Buyer will pay Seller the Fair Market Value thereof, less any damages or costs incurred by Buyer as a result of Seller's default as of the date of Buyer's Step-In. The Fair Market Value of any property as of any date shall mean the cash price obtainable in an arm's length sale between an informed and willing buyer (under no compulsion to purchase) and an informed and willing seller (under no compulsion to sell), for the property in question. Such price may be established by a bona fide offer to Seller for the purchase of such property which Seller is willing to accept or by mutual agreement of the Parties. If Fair Market Value cannot be established by the process described above, such Fair Market Value shall be the value determined in accordance with a procedure ("Appraisal Procedure") whereby two independent appraisers, one chosen by Buyer and one by Seller, shall mutually agree upon the Fair Market Value determination described herein. Buyer and Seller shall each deliver a written notice to the other appointing its appraiser within fifteen (15) Days after one Party has notified the other Party of its desire to utilize the Appraisal Procedure to establish a Fair Market Value. If, within thirty (30) Days after their appointment, the two appraisers are unable to agree to the Fair Market Value, a third independent appraiser shall be chosen within ten (10) Days thereafter by the mutual consent of such first two appraisers. However, if such first two appraisers fail to agree upon the appointment of a third appraiser, such appointment shall be made by the

AAA, or any successor organization thereof, and shall be a disinterested person qualified in the matter to be determined. The three appraisers shall make the determination of Fair Market Value in accordance with the rules of the AAA or any such successor then in effect, and such determination shall be binding and conclusive on Buyer and Seller. Each Party shall pay the costs of its own appraiser and shall share equally in the costs, if any, of a third appraiser. Seller agrees to execute and record such documents as Buyer may reasonably request to perfect Buyer's Step-In Rights.

(c) Indemnity. Buyer shall indemnify and hold harmless Seller and its joint venture partners, and each of their respective shareholders, directors, officers, employees and agents from and against any and all claims, costs, causes of action, and liabilities to the extent arising out of or in any way relating to Buyer's (or Buyer=s assignee=s, agent=s or contractor=s) operation of the Mine following Buyer's exercise of its Step-In Rights or following Buyer=s foreclosure under the Subordinated Deed of Trust.

(d) Sole Remedy. Except as otherwise specified in this Article 13, if Buyer elects to exercise its Step-In Rights or to foreclose under the Subordinated Deed of Trust, such exercise shall constitute Buyer's sole and exclusive remedies for an Event of Default of Seller under this Article 13, except for damages incurred by Buyer prior to the date of exercise of such Step-In Rights or foreclosure, and only with respect to the Event of Default giving rise to the exercise of the Step-In Rights or foreclosure.

13.05Subordinated Deed of Trust. In order to secure the full performance by Seller of its obligations under this Agreement, and to support Buyer's right to step in pursuant to Section 13.04 of this Agreement, Seller shall grant to Buyer and record within six (6) Months after the Effective Date of this Agreement a lien on and security interest in Seller's property, plant and equipment comprising the Mine by a Subordinated Deed of Trust and Security Agreement substantially in the form attached hereto and made a part hereof as Exhibit G, such UCC financing statements and other actions as Buyer may reasonably require in order to confirm and continue the validity, priority and perfection of such lien.

All present or future federal, state, municipal or other lawful taxes (other than those described in Section 20.04 (Broad Industry Taxes and Charges) below)) applicable by reason of the operation of the Mine or assessable on Seller's property or operations other than those listed in Exhibit E, shall be Seller's responsibility. Seller shall have the responsibility to pay the taxes listed in Exhibit E; provided, however, that payment of such taxes by Seller shall be without prejudice to the understanding of the Parties that the cost of such taxes shall be passed through to, and borne by Buyer as a component of the Billing Price for lignite delivered hereunder as provided in said Exhibit E to the extent the Buyer can pass such items through to the Electric Customer. Buyer shall pay all existing and any new sales, use, excise, ad valorem, and any other similar taxes, if any, imposed or levied by a governmental agency on the capacity or energy sold and delivered from the Facility. Buyer shall indemnify, defend, and hold Seller harmless from any liability for all such taxes for which Buyer is responsible. Seller shall indemnify, defend, and hold Buyer harmless from any liability from all such taxes for which Seller is responsible. Buyer shall reimburse Seller promptly on demand for the amount of any such tax that is Buyer's responsibility hereunder that Seller remits, plus any penalties and interest incurred and remitted, except such penalties as result from Seller's conduct. Likewise, Seller shall reimburse Buyer promptly on demand for the amount of any such tax that is Seller's responsibility hereunder that Buyer remits, plus any penalties, interest incurred and remitted, except penalties as a result from Buyer's conduct.

20.02Contested Taxes.

If such taxes, fees, charges or impacts of programs result in additional costs that are not otherwise assessed against Buyer, pricing under this Agreement shall be renegotiated, to fully pass through such costs to Buyer and fully reimburse Seller for such amounts, but only to the extent that Buyer is reimbursed for such amounts by the Electric Customer. These pricing renegotiations shall be subject to Arbitration only for the purpose of establishing the amount by which Seller shall be fully compensated for these additional costs. Conversely, any future tax relief (such as a tax credit) to Seller related to such pricing under this Agreement shall be fully passed through to Buyer.

20.05Income Taxes. In no event shall Seller be entitled to pass through existing, new, or increased income taxes.

THREE WAY ARBITRATION AGREEMENT

This Three-Way Arbitration Agreement (this "Agreement") is entered into and effective as of April 1, 1998, by and among the Tennessee Valley Authority, a corporate instrumentality and agency of the United States of America ( "TVA"), Choctaw Generation Limited Partnership, a Delaware limited partnership authorized to do business in the State of Mississippi ("Choctaw"), and Mississippi Lignite Mining Company, a Texas joint venture between Phillips Coal Company and The North American Coal Corporation, authorized to do business in the State of Mississippi ("MLMC"). The term “Party herein shall mean TVA, Choctaw or MLMC as the context indicates, and the term “Parties” shall mean TVA, Choctaw and MLMC.

RECITALS

A. Choctaw and MLMC are parties to a Lignite Sales Agreement dated April 1, 1998, (the “LSA”), pursuant to which MLMC will sell and Choctaw will purchase lignite as fuel for Choctaw’s lignite-

fired 440 MW atmospheric circulating fluidized bed power generation facility (the “Facility”) in Choctaw County, Mississippi.

B. Choctaw and TVA are parties to a long-term Power Purchase and Operating Agreement dated as of February 20, 1997 (the “PPOA”), whereby Choctaw will sell electric power produced at the Facility to TVA.

C. Pursuant to both the LSA and PPOA, the parties under those respective Agreements have agreed to resolve certain disputes concerning selection of new escalation indices and the impact on pricing of certain taxes (or tax credits), fee and charges imposed by state or federal government on the mining or consumption of fossil fuel for electric generating facilities (“Pass Through Charges(s)”).

THEREFORE, in consideration of the mutual premises set forth herein, and other good and valuable consideration, receipt of which is acknowledged by the Parties, the Parties agree as follows:

ARTICLE I

DISPUTE RESOLUTION

1.01 For a period of up to ninety (90) days after a Party has made claim that an index used in the LSA and PPOA is no longer published or for a Pass-Through Charge, the Parties shall engage in good faith discussions and negotiations in an attempt to resolve such claim. Such discussions shall include at least one face-to-face meeting of officers of the Parties held for the purpose of resolving the claim. If, by the earlier of the end of such ninety (90) day period (unless such period is extended by mutual agreement of the Parties), of such time as the Parties agree that a dispute exists and they have been unable to resolve such dispute, then they shall submit such dispute to binding arbitration in accordance with Article 2 below.

ARTICLE II

ARBITRATION

2.01 (a) Arbitrators' Panel. Any arbitration hereunder shall be before three (3) neutral arbitrators, who meet the qualifications set forth in Section 2.02 and who have not been employed or retained previously by any Party and do not have a direct or indirect interest in a Party or the subject matter or an arbitration between the Parties. Subject to the provision below for Alternate Arbitration Panel Selection, in the event two Parties substantially agree on the matter to be submitted to arbitration (the two such Parties being referred to as "Concurring Parties" and being considered a single party for purposes of selection of the arbitrators), the Concurring Parties and the third Party (being transferred to as the "Non-Concurring Party") shall select the three arbitrators from a panel of the American Arbitration Association ("AAA") as follows:

1) Immediately upon the expiration of the period in Section 1.01, the Concurring Parties or the Non-Concurring Party shall request the AAA to submit simultaneously to the Concurring Parties and the Non-Concurring Party an identical list of not less than fifteen (15) persons chosen from the AAA's Panel with appropriate information regarding their experience, including past arbitrations in which such person have participated and background of such persons. The Concurring Parties and the Non-Concurring Party shall have the right to provide written questions to such persons as part of the selection process and the Concurring Parties and the Non-Concurring Party shall be provided copies of such questions and such person's answers thereto.

2) Both the Concurring Parties and the Non-Concurring Party shall have thirty (30) days from the date of receipt in which to cross off any names objected to, number the remaining names to indicate the order of preference, and return the list to the AAA. If either the Concurring Parties or the Non-Concurring Party does not return the list within the time specified, all persons named therein shall be deemed acceptable to the Party that does not return the list.

3) From the persons who have been approved on both lists, and in accordance with the designated order of highest mutual preference (or a fair selection of alternating preferences of the Parties, if necessary), the AAA shall invite the acceptance of three arbitrators. If acceptable arbitrators are unable to act, or if for any other reasons the appointment cannot be made from the submitted lists, a senior official of AAA shall have the power to make the appointments from among other persons meeting the qualifications set forth in this Section and in Section 2.02, without the submission of any additional list.

(b) Alternate Arbitration Panel Selection. In the event the two Parties do not substantially agree upon the matter to be submitted to arbitration or upon mutual agreement of all Three Parties, the following method selection of the arbitration panel may be utilized. Any arbitration hereunder shall be before three (3) neutral arbitrators who meet the qualifications set forth in Section 2.02 and who have not been employed or retained previously by any Party and do not have a direct or indirect interest in a Party or the subject matter of an arbitration between the Parties, chosen by MLMC, TVA, and Choctaw from a panel of the American Arbitration Association ("AAA) as follows:

1) Immediately upon the expiration of the period in Section 1.01, MLMC, TVA or Choctaw shall request the AAA to submit simultaneously to MLMC, TVA and Choctaw an identical list of not less than fifteen (15)

persons chosen from the AAA's Panel with appropriate information regarding their experience, including past arbitrations in which such persons have participated and background of such persons. Each Party shall have the right to provide written questions to such persons as part of the selection process and all Parties shall be provided copies of such questions and such persons' answers thereto.

2) MLMC, TVA and Choctaw shall have thirty (30) days from the date of receipt in which to cross off any names objected to, number the remaining names to indicate the order of preference, and return the list to the AAA. If any one of MLMC, TVA, or Choctaw does not return the list within the time specified, all persons names therein shall be deemed acceptable to that Party.

3) From the persons who have been approved on all three lists, and in accordance with the designated order of highest mutual preference (or a fair selection of alternating preferences of the Parties, if necessary), the AAA shall invite the acceptance of three arbitrators. If acceptable arbitrators are unable to act, or if for any other reasons the appointment cannot be made from the submitted lists, a senior official of AAA shall have the power to make the appointments from among other persons meeting the qualifications set forth in this Section and in Section 2.02, without the submission of any additional list.

c) Dispute on Arbitration Selection. In the event the Parties are unable to agree on whether two Parties substantially agree upon the matter to be submitted to arbitration, the claim or claims of the Party or Parties to be submitted to arbitration and the arguments of all other Parties and any supporting materials concerning where there is substantial agreement of any two Parties upon such claims or claims shall be submitted in writing to the AAA. The AAA shall select a single arbitrator that meets the qualifications set forth in Section 2.02 and who has not been employed or retained previously by any Party and does not have a direct or indirect interest in a Party or the subject matter of an arbitration between the Parties. Within thirty (30) days of selection, the arbitrator shall make its decision solely on the matter of whether or not there is substantial agreement of any two Parties concerning the matter to be submitted to arbitration. Upon such decision, the arbitration panel's selection shall be made in accordance with Section 2.01(a) or (b) consistent with the arbitrator's written decision.

2.02 Qualification of Arbitrators. Persons selected as arbitrators hereunder shall have the following minimum qualifications:

(a) Shall be impartial, disinterested, independent of the Parties and their Affiliates and have a reputation for fairness; provided, however, that this definition shall not exclude the employees of consulting firms that have not performed consulting services having a value in excess of $50,000 in the aggregate for any Party or its Affiliates with the twenty-four (24) Months preceding the commencement of arbitration (provided that no such firm shall at the time be engaged with any Party or its Affiliates): and

(b) Shall have demonstrated and recognized expertise in the process of interpreting the pricing provisions customary in coal or lignite supply agreements and power purchase agreements.

2.03 Governing Law. Arbitration proceedings conducted pursuant to this Article 2 will be governed by the federal laws of the United States of America (without regard to its choice of law rules) and the Commercial Arbitration Rules of AAA then in effect, except to the extent such Rules may be inconsistent with this Agreement.

2.04 Claims and Responses. The claims and responses shall be filed as follows: Within thirty (30) days of the appointment of the panel or arbitrators, the Party and Parties making a claim shall submit a statement of their claim to the other Party or Parties and the panel of arbitrators. The receiving Party or Parties shall have thirty (30) days after being served with the statement of claims to submit an answer to the panel of arbitrators and the other Party or Parties. Both the Statement of claims and the answer shall concisely and with specificity state each Party's position and the basis for that position.

2.05 Hearing, Location. The arbitration hearing shall be conducted in alternating locations of the home offices of TVA and Choctaw and MLMC or such other location as may be agreed to by the Parties, provided if no other location is mutually agreeable, the arbitration hearing shall commence with TVA's office in Knoxville, Tennessee and shall begin within sixty (60) days of submittal of the answer, unless the Parties agree otherwise. The arbitration hearing shall be concluded within one hundred twenty (120) days of the appointment of the panel of arbitrators unless the Parties agree otherwise.

2.06 Authority of Arbitrator. The arbitrators' authority shall be limited to the extent that the arbitrators shall be bound by the federal laws of the United States of America, the facts and issues, and by the Federal Rules of Evidence, to the same extent as a trail court, and the arbitrators shall make no decision which is not in accordance with applicable laws and Section 2.09 hereof; depositions may be admitted to the extent testimony would be admissible and this shall not prevent live testimony by any witness who was deposed; and reasonable discovery limited to the issues to be arbitrated shall be available. The decision of the arbitrators shall be limited to a determination on the issues which may be arbitrated as set forth in Section 1.01.

2.07 Record of Hearing. A stenographic transcript of the testimony and of the record of such proceedings shall be taken.

2.08 Briefs The briefs of the Party or Parties submitting a claim shall be filed with the arbitrators within thirty (30) days after completion of the hearings, and the brief of the other Party or Parties shall be filed within thirty (30)days after the receipt of the briefs of the Party or Parties submitting the claims. The arbitrators may designate the portion or portions of the record which they require for their decision, but nothing shall prevent the Parties from presenting a complete record, if it so desires.

2.09 Issuance of Arbitrators' Decision. The award of the arbitrators shall require a majority of the arbitrators, shall be in writing setting forth the arbitrators' reasoning based on the evidence admitted and rendered and served on all Parties within thirty (30) days of filing of the last brief under Section 2.08. If with such thirty (30) day period, a majority of the arbitrators cannot reach agreement on an award, each arbitrator shall present his or her proposed decision as set forth above. Any party may then request that AAA appoint a fourth arbitrator who shall only be permitted to make an award of the proposed decision of one of the arbitrators' decisions previously set forth. Such fourth arbitrator shall render his or her decision within thirty days in writing.

2.10 Payment of Costs. Each of the Parties shall pay for the services and expenses of its representatives, witnesses, and attorneys; all other costs incurred in connection with the arbitration shall be paid as follows: fifty percent by the Non-Concurring Party, with the Concurring Parties each bearing twenty-five percent of the costs; provided that if Alternate Arbitration Panel Selection is utilized such cost shall be paid as follows: (1/3 each) by MLMC, TVA and Choctaw.

2.11 Effect of Arbitrators' Decision. The decision of the arbitrators shall be final and binding upon MLMC, TVA and Choctaw and enforceable pursuant to the laws of the United States of American and judgment thereon may be filed in any court having jurisdiction thereof. It is agreed that during the pendency of any arbitration proceedings, MLMC, TVA and Choctaw shall continue to perform their obligations under the LSA and the PPOA pending the decision of the arbitrators. To the extent necessary and proper, the arbitrators' decision shall be retroactive.

2.12 Waiver of Jury Trial. MLMC, TVA and Choctaw waive any right they may have to trial by jury in connection with proceedings or counterclaims brought by MLMC, TVA or Choctaw to enforce or appeal an arbitration award rendered under this Article 2.

ARTICLE 3

INTERACTION OF LSA AND PPOA

3.01 Parallel Pass-Throughs. MLMC and Choctaw have agreed in the LSA that no change to any indices and no Pass-Through Charge imposed on the mining of fossil fuel for electric generating facilities shall be made under the LSA unless TVA has agreed to parallel changes in the PPOA or unless a change to indices or a Pass-Through Charge is required to comply with an arbitration award or court order entered pursuant to this Agreement.

3.02 TVA Obligations Limited to PPOA. MLMC and Choctaw each acknowledge and agree that TVA has no knowledge of, has not agreed to, and is in no way bound by any provision of the LSA. TVA is obligated under the PPOA and, to the extent of Arbitration of escalation index selection and Pass-Through Charges, obligated to arbitrate pursuant to this Agreement only. In no way does TVA's acceptance of this Agreement expand its obligations as to the PPOA other than to require that the Arbitration of index selection and Pass-Through Charges be conducted among TVA, Choctaw and MLMC so that the indexes and Pass-Through Charges will be parallel between the PPOA and the LSA, but only to the extent consistent with the Provisions of the PPOA.

QUALITY & PROPERTY PRICE ADJUSTMENT

Introduction - This Exhibit J describes the methodology for calculating the daily quality adjustment to be applied to the Adjusted Base Price pursuant to Section 6.05 of the Agreement. The equations contained in this Exhibit J shall be used to calculate the change in costs that Buyer will incur at the Facility as a result of daily quality variations in the Dedicated Lignite or Alternate Fuel (collectively, “Fuel”) delivered by Seller to Buyer. These equations are based on four key parameters:

- Fuel Calorific Value

- Fuel Ash Content

- Fuel Moisture Content

- Fuel Sulfur Content

For an equivalent amount of electrical generation, the Fuel, limestone and ash flows for the daily delivered Fuel shall be calculated and compared to the material flows that would result from the use of Fuel with the specifications set forth in Section 6.01 of the Agreement. The difference in operating and maintenance costs associated with these material flows is the quality adjustment for the daily delivered Fuel.

Unit Operating and Maintenance Costs - The costs affected by changes in Fuel quality are those costs directly affected by the Fuel, ash, and limestone flow. For the purpose of calculating the cost impact of variations in Fuel quality, the base unit costs shall be as follows:

1.) Fuel Charge (CF)	[* * *] / MMBtu
2.) Fuel Handling Maintenance Cost (CFM)	[* * *] / Fuel ton
3.) Limestone Cost (CL)	[* * *] / limestone ton
4.) Limestone Maintenance Cost (CLM)	[* * *] / limestone ton
5.) Ash Disposal Cost (CA)	[* * *] / ash ton
6.) Ash Maintenance Cost (CAM)	[* * *] / ash ton
7.) Electricity Cost (CE)	[* * *] / kWhr

Where: C_F = Total Base Price - Pass-through component price

Unit Operating and Maintenance Cost Escalation- The “Unit Operating And Maintenance Costs” listed above shall be adjusted to reflect the changes in the Fuel Charge. The Fuel Charge shall be adjusted on a Monthly basis and shall be equal to the Adjusted Base Price for the current Month (in $/MMBtu) less the Pass-through component price for the current Year (in $/MMBtu)

All unit costs, other than the Fuel Charge, shall be adjusted Monthly as follows:

* * * Confidential Treatment Request

	ACxn = (CFn/[* * *]/MMBtu) x Cx
Where:	ACxn = Adjusted Unit Cost for item “x” in the current Month
	CFn= Fuel Charge for the current month ($/MMBtu)
	Cx= Unit Cost amount for item “x” set forth in “Unit Operating and
		Maintenance Costs” above
Where:	x = Items 2.) through 7.) in “Unit Operating and Maintenance Costs”
	n = current Month

Quality Adjustment - Based on the Facility parameters, Fuel quality and unit operating and maintenance costs listed above, a price adjustment for quality (“Quality Adjustment”) shall be calculated on a daily basis. The Quality Adjustment for each Month shall be equal to the sum of the daily Quality Adjustments during such Month and shall be included in Seller's Monthly invoice. The equations to be used to calculate the Quality Adjustment and an example of such adjustment calculation are set forth in the attached Quality Adjustment Table.

Annual Limestone Cap Quality Adjustment - Before January 1 of each Year Buyer and Seller shall establish a Predicted Annual Limestone Consumption (PALC) and an Annual Minimum Limestone Contract Take (AMLCT), where AMLCT equals 75% of PALC, based upon the expected annual power generation, Fuel sulfur & CaO content, and limestone quality performance. At Year-end, the PALC. will be adjusted for changes in annual power generation, and the AMLCT shall be adjusted for changes occurring during the Year due to contract limestone quality changes. The Seller's Total Annual Quality Adjustment shall be decreased or increased to the extent the actual limestone tonnage falls below the 75% Year-end PALC or above the 125% Year-end PALC times the average annual limestone unit cost.

Basic Equations

The equations contained in the Quality Adjustment Table of this Exhibit J were derived by Bums & McDonnell (Project 96-615-1 for Tractabel Power, Inc.) These equations, which are needed to calculate Fuel flow, limestone flow and ash production for a circulating fluidized bed boiler, are as follows:

Heat Input and Fuel Flow

HI =	WOUT * HR	Equation 1
HI =	WOUT * HRT/ŋ
FF =	HI
	HHV
FF =	WOUT *HR	Equation 2
	HHV
FF =	WOUT *HRT /ŋ
	HHV

* * * Confidential Treatment Request

The boiler efficiency is affected by the moisture content of the Fuel. Based on information received from Foster-Wheeler Energy Corp., the relationship between Fuel moisture and boiler efficiency in the circulating fluidized bed is:

ŋ = 0.9477 - 0.375 * %M

This boiler efficiency/lignite moisture content relationship is graphically presented at the end of this section.

Substituting the above formula for the relationship between Fuel moisture and boiler efficiency for the value of “ŋ', the above equations for heat input and Fuel flow become:

HI =	WOUT * HRT/		Equation 1a
		(0.9477 - 0.375 *%M)
FF =	WOUT * HRT/		Equation 2a
	(0.9477 - 0.375 *%M)
	HHV

Limestone Flow

L=	100	(	Ca	)	* FF * %S
	32		S
	%CaCO3

Equation 3

A relationship between the ash content and Calcium Oxide (CaO) content in the ash of the Fuel has been established. A regression formula based on over 100 core samples was developed to calculate percent CaO in the ash based on percent ash on an as-delivered basis. The regression formula is:

%CaO = (230.452 / %ash) - 3.176

The relationship between the ash content and Calcium Oxide (CaO) content in the ash is graphically presented at the end of this section.

Ash Flow

Ash flow from a CFB is made up of four parts (Fuel ash, SO₂ removal reaction products, unreacted lime and limestone inerts) as follows:

A =	[%A * FF * (1-%Ca)] +	136	* FF * %S * %R
		32

+	56	*(	Ca	-%R)	* FF * %S
	32		S

+	100	*(	Ca	)	* FF * %S * (1 - %CaCO3)
	32		S
	%CaCO3

Equation 4

Basic Calculations

The total heat input and Fuel, limestone and ash flows for the Facility design conditions are calculated from equations 1, 2, 3 and 4, respectively, using the Fuel specifications contained in Section 6.01 of the Agreement and Facility Parameters listed in this Exhibit J. Design condition parameters are identified by the subscript B. Similarly, the actual total heat input and Fuel, limestone and ash flows for the current period are calculated from equations 1a, 2a, 3 and 4, respectively, using the current period Fuel quality data. Current period parameters are identified by the subscript C. Differences between the current period values and the design condition values are used to determine the total impact of the Fuel quality change. The appropriate cost factors are then used to determine the total cost impact of the Fuel quality change as follows:

Cost Calculations:

The total change in operating and maintenance costs of the Facility is the sum of the change in Fuel costs, limestone costs, ash disposal costs, power costs and maintenance costs. Using the change in heat input and the Fuel, limestone and ash flow changes calculated above, these costs are calculated as follows:
