19

then Buyer may terminate this Agreement upon written notice to Seller, provided that such notice is delivered to Seller no later than midnight on March 12, 2003, at which time this right of termination, if unexercised, shall expire. Upon a termination by Buyer pursuant to this Section 2.3.1, neither Party shall have any liability to the other Party hereunder. Within fifteen (15) Days of the issuance of the GPSC Certificate, Buyer shall provide Seller with written notice of whether the GPSC Certificate is unconditional and, if not, whether the conditions are reasonably acceptable to Buyer.

SALE AND DELIVERY OF CAPACITY AND ENERGY

5.1                    Agreement to Sell and Purchase

5.1.1            At all times following the Delivery Commencement Date, but subject to the terms of this Agreement, Seller shall make available to Buyer the entire electrical capability of the Facility, net of Station Service, when Buyer Schedules such electrical capability. Subject to the terms of this Agreement, Buyer agrees to purchase from Seller such electrical output of the Facility, pursuant to Buyer’s Scheduling Instructions and the Designated Capacity associated with the Facility after the Delivery Commencement Date. Notwithstanding the foregoing, Seller may sell all or part of the electrical capability of the Facility and associated energy to third parties during any Conasauga Line Outage in accordance with the provisions of Section 13.3.1.

5.1.2            To the extent Buyer can practicably accept energy without harm. Buyer shall purchase from Seller the energy produced by the Facility during any Performance Test at the same price for energy delivered pursuant to the provisions of the Energy Put Agreement between Southern Company Services, Inc. and Duke Energy Trading and Marketing, L.L.C. dated January 16, 2002 (the “Energy Put Agreement”). Upon Seller’s request, Buyer will consult with Seller regarding the timing of such testing so as to maximize the resulting economic benefit for both Parties. Invoices for all such Performance Test energy will be handled pursuant to the provisions of the Energy Put Agreement.

5.1.3            Except as otherwise provided in Sections 5.1.4, 8.4 and 13.3 with respect to delivery of energy at Alternate Delivery Points, Seller shall deliver energy from the Facility to Buyer at the Interconnection Point. The risk of loss of energy shall pass from Seller to Buyer at the point of delivery. If Seller creates a control area covering the Facility, it shall promptly notify Buyer. If Buyer desires that the Facility be removed from such control area during any portion of the Teem, Buyer shall provide Seller with at least six (6) Months advance notice of such action (but such notice shall not be given before June 1, 2004). Following receipt of such notice, Buyer

27

and Seller shall discuss in good faith Buyer’s reasons for requiring that the Facility be removed from Seller’s control area and alternative ways of addressing Buyer’s concerns, but Buyer shall have the right in its sole discretion to require the Facility to be removed from Seller’s control area. Unless Buyer withdraws its notice in writing, Seller shall remove the Facility from Seller’s control area for the period beginning on the later of the (i) last Day of such six month period, or (ii) the Delivery Commencement Date and ending on the last Day of the Term, provided, however, following any such removal, Buyer shall be responsible for providing generator balancing services with respect to the Southern Company Control Area necessary for the receipt of energy pursuant to Buyer’s Schedules and for any costs thereof.

5.1.4            Following the Commercial Operation Date, in the event that the Facility is Unavailable, Seller may deliver energy at an Alternate Delivery Point from Alternate Resources in order to meet Buyer’s Schedules subject to the other provisions of this Agreement. Such Alternate Delivery Point shall be the point of interconnection between the Alternate Resources and the Transmission System, except in the case of the ▇▇▇▇▇▇ ▇▇ Generating Facility when it is connected to the Transmission System through another transmission system. Delivery of energy from Alternate Resources shall be MWh Delivered for purposes of the Monthly Availability Percentage and the Seasonal Availability Percentage calculations. In order to exercise its right to deliver energy from Alternate Resources, Seller shall provide Buyer with advance telephonic notice (to be promptly followed by written confirmation), as more fully provided in the Operating Procedures which notice shall specify the Alternate Resource(s) to be used. Seller may change Alternate Resources from time to time by notice to Buyer, provided that Alternate Resources may be changed only twice in any Day. If Seller elects to provide energy from Alternate Resources, it shall, to the extent that the designated Alternate Resources are Available, (i) provide energy from

28

such Alternate Resources for the remainder of the period for which the Facility is Unavailable, or the remainder of the calendar week in which Seller elects to use Alternate Resources, whichever is shorter, and (ii) shall provide Buyer with a uniform quantity of energy in each hour that Buyer Schedules at least that quantity of energy.

5.1.5            Notwithstanding the designation by Seller of the Designated Capacity pursuant to Appendix A, Buyer shall be entitled to Schedule the entire energy that the Facility is capable of producing when operated in accordance with Prudent Industry Practices.

5.1.6            Seller may sell any capacity or energy of the Facility not Scheduled by Buyer to any Person; provided, however, that Seller shall make such capacity and energy available to Buyer in accordance with Buyer’s Scheduling Instructions, except during periods when Seller is authorized to sell energy to third parties pursuant to this Section 5.1.

5.2                    Calculation of Monthly Capacity Payments. Subject to the terms of this Agreement, Buyer shall pay Seller a Monthly Capacity Payment calculated in accordance with Appendix A, Section B.

5.3                    Calculation of Monthly Energy Payments. Buyer shall pay Seller a Monthly Energy Payment calculated in accordance with Appendix B, Section A.

6.1                    Capacity and Energy Billing and Payment

6.1.1            Subject to the provisions of Section 6.2, by the tenth (10th) Day of each Month (commencing with July, 2005), Seller shall send Buyer an invoice stating the Monthly

29

Capacity Payment, the Monthly Energy Payment, and any Monthly Availability Adjustment or Seasonal Availability Adjustment for the immediately preceding Month (or Season in the case of the Seasonal Availability Adjustment) (“Monthly Invoice”). Seller shall also provide Buyer, by the third (3^rd) Business Day of each Month, a good faith preliminary estimate of the Monthly Invoice that will be sent for the immediately preceding Month pursuant to this Section 6.1.1; provided, however, that the failure of Seller to provide a preliminary estimate shall not alter Buyer’s obligations respecting payment.

6.1.2            All Monthly Invoices shall be due and payable by Buyer on or before the tenth (10th) Day after Buyer’s receipt of such invoice. If such tenth (10th) Day is not a Business Day, then payment shall be due on the next succeeding Business Day. Subject to the provisions of Section 6.2, Buyer shall make payment to Seller in accordance with such invoices on or before the date due in immediately available funds, through wire transfer of funds to an account designated by Seller, or other means acceptable to Seller. Interest on unpaid amounts shall accrue from the date such payments were due at a rate equal to the Interest Rate. Each Monthly Invoice shall contain a statement explaining in reasonable detail how such invoice was calculated pursuant to Sections 5.2 and 5.3.

6.2                    Billing Disputes and Final Accounting

6.2.1            If Buyer questions or contests the amount or propriety of any payment claimed by Seller to be due pursuant to this Agreement, Buyer shall make payment to Seller of amounts not in dispute, but may withhold amounts disputed in good faith until after the settlement of such question or contest in accordance with this Section 6.2. Notwithstanding the foregoing, Buyer shall not be entitled to withhold any Taxes paid by Seller which are, as between

30

Buyer and Seller, the undisputed obligation of Buyer pursuant to Section 3.5. At the time of any such withholding, Buyer shall provide Seller with a written explanation of Buyer’s reasons therefore; provided, however, that the failure of Buyer to provide such explanation shall not alter its right to withhold unless Buyer also fails to provide such written explanation within five (5) Business Days of receipt of Seller’s written inquiry concerning such withholding.

6.2.2            In the event Buyer questions or contests the correctness of any charge or credit, Buyer shall provide Seller with written notice of such amount and the basis for Buyer’s question or contest. Seller shall promptly review the questioned charge or credit and shall notify Buyer of any error in Seller’s determination of amounts owed by Buyer and issue an amended invoice in the amount of any payment that Buyer is required to make in respect of such redetermination. If Buyer disputes in good faith Seller’s amended invoice amount, then the matter shall be resolved pursuant to the provisions of Article 20 applicable to billing disputes. To the extent Seller disagrees with Buyer’s basis for questioning the original invoice, Seller shall provide a written explanation of its position.

6.2.3            Seller shall have until the end of one (1) year after the delivery of energy under this Agreement to correct any invoice for payment due for such energy and associated capacity and deliver a corrected invoice to Buyer. Buyer shall have until the end of one (1) year after its receipt of any invoice to question or contest the correctness of any charge or credit made to Buyer on such invoice. If Buyer has made payment under an invoice and thereafter questions or contests the correctness thereof, Seller shall not be required to refund any payment received from Buyer until such time as it is finally determined that Seller’s invoice was in error.

31

6.3                    Interest. If either Party does not make a payment requited by this Agreement when due, then interest at the Interest Rate from the date such overdue payment was due until such overdue payment, together with interest, is paid shall be added to the due payment. If either Party makes a payment pursuant to an invoice that is later determined to have been incorrect, then interest at the Interest Rate from the date such overpayment was made, together with interest, shall be added to the overpayment until such overpayment is refunded to such Party. Remittance received by mail, if mail is a means of payment acceptable to a Party owed such payment, will be accepted without interest charges if such payment is postmarked on or before the due date. If the due date of any payment falls on a Day other than a Business Day, the next succeeding Business Day shall be the last Day on which payment can be postmarked without interest charges being assessed. Notwithstanding this Section 6.3, no interest shall be paid with respect to any Monthly Availability Adjustment or Seasonal Availability Adjustment so long as such Monthly Availability Adjustment or Seasonal Availability Adjustment have been correctly calculated and invoiced in accordance with this Agreement.

6.4                    Billing and Payment Records. Each Party will, until the end of one (1) year after its receipt of any invoice, make available to the other Party, and each Party may audit, such books and records of the other Party as are necessary for such Party to verify the calculation of the Monthly Capacity Payments, the Monthly Energy Payments, any Monthly Availability Adjustment, any Seasonal Availability Adjustment and any other invoice, charge or payment demand made in connection with this Agreement.

9.1                    Interconnection Agreement. The Interconnection Agreement will govern the construction, ownership and operation of the Interconnection Facilities.

9.2                    Meters

9.2.1            Seller shall or shall cause others to design, locate, construct, install, own, operate and maintain the Metering System in accordance with Prudent Industry Practices in order to measure and record the amount of energy and capacity delivered from the Facility to Buyer at the Interconnection Point. The meters shall be of a mutually acceptable accuracy range and type. Neither Buyer, Seller, Seller’s Affiliates nor the employees, subcontractors or contractors of any of them shall willfully tamper with the Metering System with the intent of fraudulently or wrongly modifying the amounts paid by Buyer under this Agreement. Buyer may, at its own cost, install additional meters or other such facilities, equipment or devices on Buyer’s side of the Interconnection Point as Buyer deems necessary or appropriate to monitor the measurements of the Metering System; provided, that in all cases Seller will be entitled to base its invoiced amounts solely by reference to its own Metering System. The Parties shall mutually agree on the telemetering equipment that is appropriate to coordinate the Facility with the Scheduling Center and Seller shall, at its sole cost, install or cause the installation of such telemetering equipment. The telemetered data shall be delivered by Seller to the electrical switchyard of the Facility.

9.2.2            Seller shall or shall cause others to inspect and test all meters at such times

37

as will conform to Prudent Industry Practices, but not less often than once biennially. Seller shall be responsible for all costs and expenses incurred in connection with such inspections or tests.

9.2.3            If the Metering System fails to register, or if the measurement made by a metering device is found upon testing to vary by more than one percent (1.0%) from the measurement made by the standard meter used in the test, an adjustment shall be made correcting all measurements of energy made by the Metering System during: (i) the actual period when inaccurate measurements were made by the Metering System, if that period can be determined to the mutual satisfaction of the Parties; or (ii) if such actual period cannot be determined to the mutual satisfaction of the Parties, the second half of the period from the date of the last test of the Metering System to the date such failure is discovered or such test is made (“Adjustment Period”). If the Parties are unable to agree on the amount of the adjustment to be applied to the Adjustment Period, the amount of the adjustment shall be determined: (i) by correcting the error if the percentage of error is ascertainable by calibration, tests or mathematical calculation; or (ii) if not so ascertainable, by estimating on the basis of deliveries under similar conditions during the period since the last test. Within thirty (30) Days after the determination of the amount of any adjustment, Buyer shall pay Seller any additional amounts then due for deliveries of energy or Designated Capacity during the Adjustment Period or Buyer shall be entitled to a credit against any subsequent payments for energy or Designated Capacity, as the case may be.

9.2.4            Buyer and its representatives shall be entitled to be present at any test, inspection, maintenance and replacement of any part of the Metering System relating to obligations under this Agreement.

ARTICLE 11

OPERATION AND MAINTENANCE

11.1              Operation and Maintenance

11.1.1 Seller shall or shall cause others to manage, control, operate and maintain all parts of the Facility in a manner consistent with Prudent Industry Practices, taking into account Buyer’s right to Schedule the Facility, and in accordance with applicable planning standards and operating policies of the SERC and NERC and in accordance with the Operating Procedures to be developed by the Operating Committee. Seller shall and shall cause others to: (i) be in compliance with all Legal Requirements applicable to Seller and to the owner and operator of the Facility and (ii) diligently seek to obtain, maintain, comply with and, as necessary, renew and modify from time to time, any and all Consents. Notwithstanding the foregoing, a failure by Seller to comply with the provisions of this Section 11.1.1 shall not constitute an Event of Default under Section 17.1.5; provided, however, that Buyer shall have the right to seek the remedy of specific performance with respect to any such failure.

11.1.2 Seller and Buyer shall mutually develop written Operating Procedures no later than sixty (60) Days prior to the Required Commercial Operation Date. Topics covered shall include deliveries of energy during start-up and testing of the Facility; the method of

40

day-to-day communications; clearance and switching practices; daily capacity availability and energy reports; Facility operations log; reactive power output; technical limits regarding Facility operation (such as minimum run times, minimum down times between starts, and other limits specified in Appendix C); ramp rates for the delivery of power to the Transmission System; coordination of maintenance scheduling; designation of confidential information and such other matters as the Operating Representatives shall agree are appropriate. The Operating Representatives shall be responsible for modifying, from time to time, these Operating Procedures in writing to reflect agreed upon changes. In the event of inconsistency or conflict between the Operating Procedures and specific terms of this Agreement, the specific terms of this Agreement shall take precedence.

11.1.3 Seller shall or shall cause others to employ at the Facility all safety devices and safety practices required by Prudent Industry Practices. To the extent consistent with Prudent Industry Practices, Seller shall keep accurate records of any accident or other occurrence at the Site that results in injury to persons or damage to property. Seller shall provide to Buyer reasonable access to these records upon not less than seven (7) Days notice during normal business hours, but shall not be required to provide access to employment records regarding Facility personnel.

11.2              Maintenance Scheduling

11.2.1 Commencing in 2004 and each year thereafter, Seller shall submit to Buyer, before September 1, maintenance schedules and outage plans for the Facility that conform to Prudent Industry Practices for similar equipment, including in terms of frequency and duration (“Maintenance Schedules”), for the next four (4) Annual Periods or the number of such Annual

41

Periods remaining in the Term, whichever is less. Seller stall not schedule any maintenance of the Facility during the Months of May through September of any Annual Period that would decrease the capacity output of the Facility below the Designated Capacity without the prior written consent of Buyer. Buyer shall have thirty (30) Days to review the proposed Maintenance Schedules and may propose changes to the Maintenance Schedule for the next Annual Period provided that they are reasonable in light of the burdens that such changes impose on Seller compared to the burdens avoided by Buyer as a result of such changes and do not delay any scheduled maintenance to a later Annual Period. Any such changes proposed by Buyer shall be accompanied by an explanation of the reasons that Buyer requires such changes. Such changes shall be incorporated into the Maintenance Schedules for such next Annual Period within thirty (30) Days, to the extent that they involve maintenance scheduled during the Months of January or February. To the extent that such changes involve maintenance scheduled during the Months of March, April, October, November or December, they shall also be incorporated into the Maintenance Schedules unless Seller provides supporting documentation within thirty (30) Days demonstrating that such changes (a) will cause Seller to incur incremental additional costs that are material, or (b) would be contrary to Prudent Industry Practices. Notwithstanding the foregoing, Seller shall not be required to incorporate any changes that (w) would reasonably be expected to result in equipment damage or excessive degradation, (x) would reasonably be expected to result in voiding Seller’s equipment warranty, (y) would reasonably be expected to cause Seller to violate its obligations under its existing long term maintenance agreement with the General Electric Company in any material respect; or (z) would require Seller to conduct maintenance at the same time as Seller has scheduled maintenance at the Seller’s ▇▇▇▇▇▇ ▇▇ Generating Facility. In the event that Seller is not required to accept Buyer’s proposed

42

Maintenance Schedule changes in the Months of March, April, October, November or December because such changes will cause Seller to incur material incremental costs, Buyer and Seller agree to use commercially reasonable efforts to promptly develop Maintenance Schedules that are reasonably acceptable to the Parties, considering the burdens that Buyer’s changes impose on Seller compared to the burdens avoided by Buyer as a result of such changes. Any dispute concerning this Section 11.2.1 shall be resolved in accordance with the provisions of Article 20 applicable to Maintenance Schedule disputes. The outages scheduled in the final approved Maintenance Schedule shall be the “Scheduled Outages” for purposes of this Agreement.

11.2.2 In addition to Scheduled Outages, Seller may request an unlimited number of Maintenance Outages during any Annual Period. Seller shall request each Maintenance Outage at least twenty-four (24) hours in advance. Such request shall identify the equipment and Designated Capacity that will not be available for Schedule and the proposed start time and duration for the Maintenance Outage. Buyer shall respond to Seller’s request as soon as reasonably practicable. Seller shall not take a Maintenance Outage without Buyer’s prior written or telephonic consent, and such consent shall not be unreasonably withheld, conditioned or delayed; provided, however, that the Parties acknowledge that it shall be reasonable for Buyer to deny any request for a Maintenance Outage if Buyer reasonably believes that it may Schedule the Facility to a level that would require the availability of the equipment that is proposed to be unavailable during the Maintenance Outage. Buyer shall have the right to revoke its consent to a Maintenance Outage if changed conditions require Scheduling of the Designated Capacity scheduled to be unavailable during such Maintenance Outage; provided, however, that Buyer may only revoke its consent if it provides Seller with notice of revocation at least twelve (12) hours prior to the scheduled start of the Maintenance Outage. In addition, if Buyer reasonably

43

requests Seller to return all or part of that portion of the Facility that is affected by the Maintenance Outage to full availability status, Seller shall comply as soon as reasonably practical.

11.3              Access to the Site and the Facility

11.3.1. Seller grants and has caused others to grant Buyer, its designated employees and agents the right to enter the Site with such prior notice to Seller as is reasonable to: (i) install, operate, maintain, replace and/or remove the Interconnection Facilities; (ii) inspect, maintain, and test meters and other Buyer equipment; (iii) interconnect, interrupt, monitor, or measure energy generated by the Facility in accordance with the terms of this Agreement; (iv) monitor Performance Tests; (v) inspect the Facility, and (vi) inspect and test facilities related to the supply of Natural Gas. All activities of Buyer, its designated employees and agents at the Site shall be subject to the rules and procedures of Seller and the owner or operator of the Facility (including, without limitation, those related to health and safety).

11.4              Availability of Records. Seller shall or shall cause others to keep accurate records and all other data necessary for the purposes of proper administration of this Agreement in accordance with the following guidelines:

11.4.1 All such records shall be maintained for a minimum of two (2) years after the creation of such record or data and for any additional period of time required by Governmental Authorities with jurisdiction over Seller, provided, however, that such records will be kept for as long as is necessary to complete any audit that began or was announced during such two-year period.

11.4.2 An accurate and up-to-date operating log shall be maintained at the Facility with records of: (i) real and reactive power production for each clock hour; (ii) changes

44

in operating status; (iii) Scheduled Outages, Maintenance Outages and Forced Outages; (iv) any unusual conditions found during inspections; and (v) any significant events related to the operation of the Facility.

11.4.3 Buyer shall have the right from time to time, upon not less than seven (7) Days notice to Seller and during normal business hours, to examine the records and data relating to this Agreement.

11.5              Disclaimer. Seller understands and agrees that Buyer’s receipt and review of any material related to the Project or any physical inspection of the Facility conducted by Buyer under any provision of this Agreement is solely for its own information. By conducting such reviews or inspections, Buyer makes no endorsement of the design or representation or warranty of the safety, durability or reliability of the Facility, all of which are the sole responsibility of Seller in accordance with the terms of this Agreement, and Buyer shall not be deemed to have accepted any condition of the Facility that is not in full compliance with the terms hereof. Seller shall in no way represent to any third party that, as a result of the Buyer’s receipt and review of any material or any inspections, Buyer is in any way responsible for the engineering or construction soundness of the Facility.

11.6              Operating Committee

11.6.1 The Parties shall establish an Operating Committee comprised of two (2) Operating Representatives, one (1) appointed by each of Seller and Buyer. Seller and Buyer, as the case may be, shall provide written notice of such appointments to the other Party. Such appointments may be changed at any time by similar written notice. The Operating

45

Representatives shall meet as necessary, but not less often than once each calendar year, at a mutually agreeable time and place upon prior written notice. The Operating Representatives shall represent the Parties in all matters arising hereunder that may be delegated to them by mutual agreement of the Parties, but shall not have the authority to modify or amend the terms of this Agreement.

11.6.2 Each Party shall cooperate in providing to the Operating Representatives all information required in the performance of their duties. If the Operating Representatives are unable to agree on any matter falling under their jurisdiction, such matter shall be submitted to senior officers for discussion and resolution. All decisions and agreements made by the Operating Representatives or their principals shall be evidenced in writing.

11.7              Equipment Failures

11.7.1 If the Facility suffers a Forced Outage due to equipment failure, Seller shall use commercially reasonable efforts to repair the Facility and end the Forced Outage as soon as practicable under the circumstances. If a Party believes in good faith that the Forced Outage will have a duration of longer than one (1) Month, Seller shall, or Buyer may request that Seller, provide a repair plan which shall describe, to the extent known, (i) the cause of the Forced Outage, (ii) the efforts to be taken by Seller to repair the Facility, and (iii) the estimated duration of the Forced Outage. Seller shall update its repair plan from time to time as additional information becomes available.

11.7.2 If Seller estimates in good faith in its repair plan, or in any update to its repair plan, that the Forced Outage will have a duration of fifteen (15) Months or longer, or if the Forced Outage continues for more than twenty-four (24) Months, then either Party shall have the

46

right, upon prior written notice received by the other Party within thirty (30) Days of receipt by Buyer of Seller’s repair plan, or update to such repair plan, as the case may be, or at any time which is more than twenty-four (24) Months following the beginning of such Forced Outage, to terminate this Agreement effective on the thirtieth (30^th) Day following receipt of such notice. The effective date of such termination shall be deemed to be an Early Termination Date within the meaning of Section 17.3.1, and Buyer shall be entitled, as its sole remedy in respect of such termination, to receive the Termination Payment pursuant to Section 17.3.2 (calculated as if Buyer were the Non-Defaulting Party); provided, however, that in the case where Buyer elects to terminate this Agreement pursuant to this Section 11.7.2, if the Forced Outage was not caused by a failure to operate or maintain the Facility in accordance with Prudent Industry Practices, such Termination Payment shall not exceed [***] provided further that in the case where Seller elects to terminate this Agreement pursuant to this Section 11.7.2, Seller’s estimated return-to-service date in its latest repair plan shall be deemed to be the Early Termination Date within the meaning of Section 17.3.1. Any dispute between the Parties concerning Seller’s estimated return-to-service date in any repair plan submitted to Buyer pursuant to this Section 11.7.2 shall be resolved in accordance with the provisions of Article 20 applicable to such repair plans.

FUEL SUPPLY

12.1              Primary Fuel Supply Plan.

12.1.1 Except as otherwise provided in this Agreement, Seller shall have sole responsibility for making available to the Facility the quantities of Natural Gas at the rates of

*** Certain information on this page has been omitted and filed separately with the SEC.  Confidential treatment has been requested with respect to the omitted portions.

47

delivery required to accommodate Buyer’s Scheduling Instructions, subject to the scheduling flexibility permitted by the application of the pipeline’s tariff. If Seller is unable to meet Buyer’s Schedule as a result of Seller’s failure to provide the required quantities of Natural Gas for reasons other than a Force Majeure Event, Seller shall reimburse Buyer for the Incremental Replacement Cost of the energy that Seller is unable to provide.

12.2              Natural Gas Transportation Capacity.

12.2.1 Except as otherwise provided in this Agreement, Seller shall bear all actual costs incurred to provide delivered Natural Gas to the Facility in order to meet Buyer’s Schedules.

12.2.2 At Seller’s expense Seller shall acquire, construct, own, operate and maintain, all facilities, infrastructures and property interests that are necessary for Seller to receive, measure and use Natural Gas which Seller is required to deliver pursuant to this Agreement so as to enable the Facility to produce energy as committed to Buyer under this Agreement.

12.2.3 Seller shall have the right, pursuant to this Section 12.2.3, to designate firm transportation capacity on the Texas Eastern Transmission Company Pipeline, the Tennessee Gas Pipeline or the Southern Natural Gas Pipeline (whether firm, released firm or other options that provide firm transportation capacity) to serve this Agreement. Such designation shall be made by written notice to Buyer given, with respect to firm transportation capacity acquired by Seller prior to February 1, 2005, on or before May 1, 2005, and with respect to firm transportation capacity acquired by Seller after February 1, 2005, on or before the date [***] after the date of acquisition of such transportation capacity. Each notice shall

48

provide detailed information as to such firm transmission capacity, including, without limitation, the terms thereof and the actual cost to Seller of acquiring such firm transportation capacity, and shall be accompanied with a copy of the contract or other agreement pursuant to which such transaction capacity is being provided. The designation of firm transportation capacity to serve this Agreement (any such capacity being hereinafter referred to as “Earmarked Capacity”), shall not restrict the ability of Seller to modify the terms thereof to assign, transfer or release all or any part thereof, but for as long as any such Earmarked Capacity is held by Seller, such Earmarked Capacity shall, to the extent not already used to provide Natural Gas to meet Buyer’s Schedules, be made available to Buyer to transport Natural Gas supplied by Buyer pursuant to Section 12.4. Earmarked Capacity shall be deemed to be the first transportation capacity used to meet Buyer’s Schedules. Seller shall provide Buyer prompt written notice of any modification to the terms of, or assignment, transfer or release of any Earmarked Capacity, and to extent assigned, transferred or released, such transportation capacity shall no longer be considered Earmarked Capacity.

12.3              Energy Price. Buyer shall pay, in accordance with Appendix B, for energy that is, delivered to Buyer pursuant to the Buyer’s Scheduling Instructions, including energy received during periods of ramp up and ramp down. Subject to Section 5.1.2, Buyer is not responsible for costs associated with generating energy at the Facility for any other purposes, including (but not limited to) Station Service, initial start-up, testing and synchronization of the Facility and sales to third parties.

12.4              Intraday Gas.

12.4.1 When energy is scheduled pursuant to intraday Scheduling parameters

49

prior to the Tolling Commencement Date, Seller will provide Buyer a commodity gas price for supplying Natural Gas to the Facility, or for buying back excess Natural Gas resulting from an intraday Schedule decrease, as appropriate. Buyer shall have the option of (i) not changing the existing Scheduling Instruction, (ii) proceeding with the intraday Scheduling increase or decrease based on the quoted price (to buy the incremental gas supply, or to “sell-back” the excess Natural Gas supply, as applicable), (iii) proceeding with the intraday Scheduling increase and notifying Seller that Buyer will supply the required incremental Natural Gas supply (a) into the East Tennessee Pipeline for delivery to the Facility, or (b) at the receipt point of any Earmarked Capacity available to meet Buyer’s intraday Schedules pursuant to Section 12.2.3, if applicable, and in either case, Buyer shall be obligated to pay the Fuel Use and Commodity Rate for such quantity of Natural Gas determined pursuant to Appendix B, Section D, or (iv) proceeding with the intraday Scheduling decrease and purchase from Seller at Seller’s quoted price, and take delivery of, all surplus Natural Gas supply resulting from the intraday Scheduling decrease.

12.5              Alternative Fuel Supply Arrangements

12.5.1 If Buyer desires additional intraday scheduling flexibility, Buyer may during the Month of [***] in any year, commencing with [***] give Seller notice of its election to supply Natural Gas to the Facility to meet its Schedules. Any such notice shall, unless withdrawn, be effective on [***] of the calendar year following the year in which such notice is given (the “Tolling Commencement Date”).

12.5.2 Effective on the Tolling Commencement Date, for the remainder of the Term (i) Seller shall be relieved of all obligations under this Agreement to supply Natural Gas to the Facility to meet Buyer’s Schedules and, except as provided in Section 12.5.3, to make Natural

50

Gas transportation capacity available to transport Natural Gas to the Facility, and (ii) Buyer shall bear all actual costs incurred to provide delivered Natural Gas to the Facility in order to meet its Schedules, which, in the case of charges imposed by East Tennessee, shall, with respect to the firm transportation capacity made available to Buyer by Seller pursuant to the last sentence of this Section 12.5.2, be [***] and [***] Buyer shall retain title to Natural Gas provided by Buyer on and after the Tolling Commencement Date, the title to all energy generated by the Facility as a result of the conversion of such Natural Gas to energy in the Facility shall vest in Buyer immediately upon generation thereof and this Agreement shall be treated as creating a tolling arrangement pursuant to which Seller makes the Facility available to Buyer to convert Buyer’s Natural Gas into Buyer’s energy. Notwithstanding the foregoing, risk of loss of Natural Gas shall pass from Buyer to Seller at the delivery point into East Tennessee or such other point as to which Buyer and Seller may agree, and risk of loss of energy generated at the Facility shall pass from Seller to Buyer at the Interconnection Point. From and after the Tolling Commencement Date for the remainder of the Term, Seller shall make available to Seller [***] of the firm Natural Gas transportation capacity on East Tennessee held by Seller on the date of this Agreement to meet Buyer’s Schedules.

12.5.3 Effective on the Tolling Commencement Date, Seller shall convey to Buyer by assignment, release or other means all Earmarked Capacity in accordance with the pipeline’s tariffs and in a manner that, to the extent possible, preserves the economic benefits of such firm transportation capacity. Seller shall be responsible for, and shall indemnify and hold Buyer and its Affiliates harmless from, all costs, expenses and liabilities in respect of the Earmarked Capacity conveyed to Buyer to the extent such costs, expenses and liabilities relate to periods prior to the Tolling Commencement Date and Buyer shall be responsible for, and shall

51

indemnify and hold Seller and its Affiliates harmless from, and shall obtain the release of Seller and its Affiliates from, any and all costs, expenses and liabilities in respect of the Earmarked Capacity conveyed to Buyer to the extent such costs, expenses and liabilities relate to periods on or after the Tolling Commencement Date.

12.5.4 The Parties agree to put into place procedures effective as of the Tolling Commencement Date which (i) preserve for the Parties the economic effect of the heat rates used in the calculation of the energy price to meet Buyer’s Schedules (including ramp-ups and ramp-downs) prior to the Tolling Commencement Date, (ii) provide for the delivery of Natural Gas to the Facility at Seller’s expense (based on Buyer’s actual costs) to allow Seller to fulfill its obligations under this Agreement, including Station Service and initial start-up Natural Gas to meet Buyer’s Schedules and Natural Gas consumed for testing and synchronization of the Facility, (iii) preserves the ability of Seller to provide Natural Gas to the Facility at its own cost and expense for purposes other than meeting Buyer’s Schedules, or otherwise fulfilling its obligations under this Agreement, (iv) provide for the appropriate metering of Natural Gas for the Facility, (v) result in each Party being responsible for its own Natural Gas imbalance penalties, and (vi) provide for such other matters as to which the Parties agree are necessary or appropriate for restructuring this Agreement as a tolling arrangement; provided, however, that neither Party shall have any obligation to agree to any procedures that modify the economic arrangements (other than Natural Gas supply) contained in this Agreement or benefits of this Agreement to such Party. The Parties agree that Buyer is not responsible for the costs incurred with generating energy at the Facility for any purposes other than pursuant to Buyer’s Schedules, including (but not limited to) Station Service, initial start-up, testing and synchronization of the Facility and sales to third parties. Either Party may, at any time after June 1, 2003, request that

52

work on such procedures commence with the objective of completing such procedures within ninety (90) Days after commencement thereof.

ARTICLE 13

ENERGY SCHEDULING AND TRANSMISSION

13.1              Coordination and Scheduling.

13.1.1 Buyer and Seller agree to Schedule the Facility in accordance with the procedures set forth in this Section 13.1 and Appendix C, Section II Seller is not obligated to deliver energy in response to those portions of Scheduling Instructions that materially deviate from such procedures.

13.1.2 The electrical output committed under this Agreement shall be subject to Scheduling Instructions issued by the Scheduling Center. Seller shall cause the Facility operator to comply with such Scheduling Instructions at the time designated for compliance therewith, subject to Prudent Industry Practices, the Technical Limits and the Scheduling procedures set forth in Appendix C. At the request of Buyer, Seller shall make reasonable efforts to cause the Facility to control voltage by producing or absorbing reactive power subject to the Technical Limits and other technical operating constraints; provided, however, that such actions do not cause Seller to violate any provisions of its Interconnection Agreement and provided that Buyer shall reimburse Seller for any incremental costs incurred by Seller (including the cost of reduced output), in excess of those costs Seller would have incurred under the Interconnection Agreement, as a result of Seller’s compliance with any such requests.

13.1.3 Buyer covenants that determinations to submit Scheduling Instructions to Seller shall be based solely on considerations of the reliability of Buyer’s system, economic

53

dispatch order and the costs associated with economic unit commitment, and not on the availability status of the Facility or any impact that the determination may have on Monthly Capacity Payments.

13.1.4 Buyer and Seller shall maintain written records of the quantities of energy to be delivered each hour during the Term. Following the Delivery Commencement Date, Buyer may Schedule energy at any time during the Term and Seller shall cause the entire output capability of the Facility to be available to Buyer when Scheduled.

13.1.4.1 If Buyer elects to Schedule energy for delivery on the next Business Day, Buyer shall provide its Schedule for such delivery to Seller no later than 8:30 a.m. CPT on the Business Day prior to the Day of delivery. This day-ahead Scheduling Instruction will also include any electric deliveries from midnight to midnight for any calendar Days that precede the next Business Day (i.e. weekends and holidays). Buyer shall also provide a non-binding, good faith estimate of its Scheduling Instructions for the twenty-four (24) hour period following the next Business Day. Subject to any then existing tariff provisions and operational constraints of the upstream pipelines, including any scheduling flexibility offered by the pipeline operator, Buyer may submit Scheduling Instructions for each hour in increments of fifty (50) MW, which may vary hour to hour, subject to a minimum of two hundred (200) MW up to the full Base Energy output capability. Each Scheduling Instruction shall cover a minimum period of eight (8) consecutive hours. Supplemental Energy may also be Scheduled by Buyer at the full Designated Supplemental Capacity each hour subject to a minimum of four (4) consecutive hours per Day. Scheduling of the entire Designated Base Capacity is a prerequisite to the Scheduling of Supplemental Energy. Buyer will be required to accept and pay for energy during ramp up and ramp down periods at a price which reflects the heat rate for the Scheduled amount, but

54

otherwise as determined for Base Energy or Supplemental Energy, as the case may be.

13.1.4.2 For Scheduling Instructions submitted after the day-ahead deadline, Buyer must provide Seller with a proposed revised Schedule at least two (2) hours prior to the start-up or ramp up of energy delivery, subject to any then existing tariff provisions and operational constraints of the upstream pipelines, including any scheduling flexibility offered by the pipeline operator. Within thirty (30) minutes thereafter, Seller will provide Buyer with an estimate of the economic consequences of such intraday Scheduling Instruction after which Buyer shall notify Seller no later than thirty (30) minutes following receipt of Seller’s estimate if it elects to implement such intraday Scheduling Instructions. If energy is not already Scheduled, Buyer will be assessed a turbine start event, in accordance with Appendix B, Section C. Buyer will be responsible for the actual costs of implementing the intraday Scheduling Instruction, including any associated imbalance penalties, if any, assessed by The Southern Company pursuant to the Southern OATT, and by the gas transportation providers. As provided in Section 12.4, Buyer shall have the right to supply its own intraday gas commodity if it elects not to utilize the gas commodity offered by Seller for the intraday Schedule Instruction.

13.1.4.3 Notwithstanding anything contained in Section 13.1.4.2 to the contrary, if Seller elects to meet Buyer’s Schedules from Alternate Resource(s), (i) Buyer shall not have the right to give intraday Scheduling Instructions during the calendar week in which Alternate Resource(s) are first used as a result of any Forced Outage, and (ii) thereafter, Buyer’s right to give intraday Scheduling Instructions shall be subject to any then existing tariff provisions and operational constraints of the upstream pipelines, including any scheduling flexibility offered by the pipeline operator, serving the Alternate Resource(s).

13.1.5 Seller may from time to time request that the Facility be allowed to deliver

55

electric energy output to Buyer in order to test and/or evaluate Facility equipment (“Operator Requested Schedule”). Seller shall request such Operator Requested Schedule from Buyer at least one (1) Business Day in advance, and Buyer shall have the right to approve such Operator Requested Schedule (such approval not to be unreasonably withheld, conditioned or delayed). If, for whatever reason, Buyer determines that it is necessary to Schedule the Facility during an Operator Requested Schedule, then Buyer may cancel or interrupt, as the case may be, the Operator Requested Schedule and subsequently Schedule the Facility as it deems appropriate. Payment for any energy delivered resultant from any such Operator Requested Schedule will be as described in Section 5.1.2 of this Agreement.

13.2              Effect of System Emergencies. The Parties recognize that pursuant to the Interconnection Agreement, Seller may be required to take certain actions during System Emergencies and may be required to disconnect the Facility from the Transmission System to allow for repair or maintenance on the Interconnection Facilities or the Transmission System. Subject to the provisions of Section 13.3, to the extent that Seller is required pursuant to the Interconnection Agreement to take any action, other than instances where Seller’s acts or omissions are the cause for the required actions, which will adversely affect its ability to meet Buyer’s Schedules, Seller shall be excused from meeting Buyer’s Schedules and the amount of energy that Seller is unable to deliver to Buyer as a result of such action shall not be treated as MWh Scheduled.

13.3              Effect of Certain Transmission Constraints.

13.3.1 If, as a result of an outage (a “Conasauga Line Outage”) on that segment of the Transmission System consisting of the 500 kV transmission line between the Conasauga 500 kV

56

substation and the ▇▇▇▇▇ 500 kV substation (or, if different than the ▇▇▇▇▇ 500 kV substation, the substation closest to the Conasauga 500 kV substation to its south), Buyer is unable to use such segment for the transmission of energy from the Facility to Buyer’s loads, Buyer shall have the right to require Seller to deliver energy Scheduled during the remainder of the Conasauga Line Outage to an Alternate Delivery Point, and shall be entitled, for the period during which energy is to be delivered at the Alternate Delivery Point, to redesignate the Facility as not being a network resource pursuant to the Southern OATT. Buyer shall have the right to make separate elections as to whether to accept energy at the Delivery Point or an Alternate Delivery Point for each week of the Conasauga Line Outage. The first such election shall be made upon at least two (2) hours’ prior notice and each subsequent election shall be made upon at least twenty-four (24) hours’ prior written notice. Following receipt of a notice from Buyer requiring that energy be delivered at an Alternate Delivery Point, Seller shall, for energy Scheduled during the period covered by such notice, have the option either to (i) deliver the Scheduled energy at any Alternate Delivery Point selected by Seller either from the Facility or from Alternate Resources, or (ii) treat the Facility as being Unavailable as a result of a Forced Outage; provided, however, that in either case, and unless Seller elects to deliver energy from the Facility to Buyer, Seller shall have the right to sell the electrical capability of and the associated energy from the Facility to third parties during the period covered by such notice. Buyer shall provide Seller with prompt written notice of any Conasauga Line Outage and shall keep Seller fully informed as to the facts and circumstances surrounding such outage.

13.3.2 The Parties agree that Buyer and its Affiliates have no intention or obligation to expand the Transmission System in order to establish a separate electrical circuit connecting the Interconnection Point to the Transmission System. Buyer shall have no obligation

57

to cause modifications to the Transmission System in preparation for the receipt and transmission of energy from Alternate Resources anytime during the Term.

13.3.3 Following the Delivery Commencement Date, in the event that constraints are imposed upon the Facility by the security coordinator of the transmission system of the Tennessee Valley Authority or are imposed on the Facility (but not on other native load facilities of The Southern Company and its Affiliates) by the security coordinator of a transmission system other than the Transmission System or the transmission system of the Tennessee Valley Authority (a “Transmission System Constraint”), the following provisions shall apply:

13.3.3.1 The Parties agree that fifty percent (50%) of MWh Scheduled which Seller is unable to deliver or which Buyer is unable to receive as a result of any Transmission System Constraint shall be included as MWh Delivered for purposes of the Monthly Availability Percentage and the Seasonal Availability Percentage calculations performed pursuant to Appendix A, Sections C and D. Each Party shall provide the other Party with prompt written notice of any Transmission System Constraints and the facts and circumstances surrounding such constraints.

13.3.3.2 If, as a result of the imposition of Transmission System Constraints, the Facility is unable to deliver or Buyer is unable to receive five percent (5%) of the MWh Scheduled during any period of one hundred twenty (120) Days in which Buyer Schedules energy in at least eight hundred (800) hours, either Party shall have the right, upon thirty (30) Days prior written notice to the other Party, to require that the Tested Reliable Capacity be reduced to an amount equal to a capacity level which, based on Buyer’s actual Schedules during such period and if such capacity level were the declared Designated Capacity, would have reduced the MWh Scheduled that Seller was unable to deliver as a result of the imposition of

58

Transmission System Constraints to two percent (2%) of the total MWh Scheduled during such period, with the amount of any such reduction being applied pro-rata to Tested Base Capacity and to Tested Supplemental Capacity. Such reduction shall be effective as of the date thirty-one (31) Days after receipt of such notice. Thereafter, the Tested Reliable Capacity determined pursuant to a Performance Test shall not exceed the amount determined pursuant to this Section 13.3.3.2, unless Seller provides Buyer with credible evidence that the effect of any Transmission System Constraints has been mitigated.

13.3.3.2.1 Within five (5) Business Days after the reduction of the Tested Reliable Capacity pursuant to the first sentence of Section 13.3.3.2, Seller shall, by written notice to Buyer, re-establish the Designated Base Capacity and the Designated Supplemental Capacity at levels which do not exceed the then current Tested Base Capacity and Tested Supplemental Capacity, and in the absence of any such notice, the Designated Base Capacity shall be equal to the Tested Base Capacity and the Designated Supplemental Capacity shall be equal to the Tested Supplemental Capacity.

13.3.3.2.2 If the Tested Reliable Capacity as reduced pursuant to the first sentence of Section 13.3.3.2 is less than two hundred eighty (280) MW, either Party shall have the right, upon ninety (90) Days prior written notice to the other Party, to terminate this Agreement. Following such termination, neither Party shall have any further liability or obligation hereunder except for any liability accrued prior to the effective date of such termination.

All such insurance shall be written by a company or companies with a Best’s rating of no less than “A.”

14.1.2 To the extent of the indemnities assumed by Seller hereunder, Buyer shall be designated as an additional insured as its interests may appear on all required policies, and each such policy shall be primary and shall not contribute to any insurance that may otherwise be maintained by, or on behalf of, Buyer.

14.1.3 To the extent of the indemnities assumed by Seller hereunder, all insurance required hereunder shall contain provisions waiving the insured’s and the insurer’s rights of subrogation or recovery of any kind against Buyer, its Affiliates and their respective agents, employees, officers, directors, successors and assigns.

14.1.4 Buyer shall acquire and maintain at its sole cost and expense, the types and amounts of insurance coverage as are consistent with Prudent Industry Practices but in no event less than the types and amounts described in Appendix E and this Article 14.

60

14.1.6 Notwithstanding this Agreement’s insurance requirements, each Party may self-insure all or any part of the insurance coverage provided for in this Agreement, subject to the other Party’s prior written consent. All self-insurance coverage shall be treated as if it were an insurance policy.

14.2              Certificates of Insurance-Seller. Within ten (10) Days of the execution of this Agreement, Seller will provide Buyer with certificates of insurance evidencing the required coverage set forth above and in Appendix E. Such certificates shall provide for a minimum of thirty (30) Days advance notice to Buyer of cancellation or material change in coverage. Failure by Seller to cause the procurement of the insurance coverage or the delivery of certificates of insurance required by this Article 14 or Appendix E shall not relieve Seller of the insurance requirements set forth herein or therein or in any way relieve or limit Seller’s obligations and liabilities under any other provision of this Agreement.

14.3              Certificates of Insurance-Buyer. Within ten (10) Days of the execution of this Agreement, Buyer will provide Seller with certificates of insurance evidencing the required coverage set forth above and in Appendix E.

ARTICLE 15

INDEMNIFICATION

15.1              Scope of Indemnity. Each Party (the “Indemnifying Party”) expressly agrees to indemnify, hold harmless and defend the other Party and its Affiliates, trustees, agents, officers, directors, employees, members and permitted assigns (“Indemnified Party”) against all claims, liability, costs or expenses (on an After-Tax Basis) for loss, damage or injury to the person or property of third parties in any manner directly or indirectly related to: (a) activities on the Indemnifying Party’s respective side of the Interconnection Point (in the case of such loss, damage or injury related to the generation, transmission or distribution of energy); or (b) any other activities to the extent that they involved the negligence or willful misconduct of the Indemnifying Party, unless such loss, damage or injury is the result of the negligence or willful misconduct of the Indemnified Party. Further, Seller agrees to indemnify, hold harmless and defend Buyer and its Affiliates, trustees, agents, officers, directors, employees, members and permitted assigns against all claims, liability, costs or expenses (on an After-Tax Basis) (x) imposed by any transmission system owner or operator (other than those of the Transmission System) and arising from the testing or operation of the Facility, or (y) arising from the negligence or willful misconduct of any Facility owner or operator.

15.2              Notice of Proceedings. An Indemnified Party which becomes entitled to indemnification under this Agreement shall promptly notify the other Party of any claim or proceeding in respect of which it is to be indemnified. Such notice shall be given as soon as reasonably practicable after the Indemnified Party obligated to give such notice becomes aware of such claim or proceeding. Failure to give

62

such notice shall not excuse an indemnification obligation except to the extent failure to provide notice adversely affects the Indemnifying Party’s interests. The Indemnifying Party shall assume the defense thereof with counsel designated by the Indemnifying Party; provided, however, that if the defendants in any such action include both the Indemnified Party and the Indemnifying Party and the Indemnified Party reasonably concludes that there may be legal defenses available to it that are different from or additional to, or inconsistent with, those available to the Indemnifying Party, the Indemnified Party shall have the right to select and be represented by separate counsel, at the expense of the Indemnifying Party. If the Indemnifying Party fails to assume the defense of a claim, the indemnification of which is required under this Agreement, the Indemnified Party may, at the expense of the Indemnifying Party, contest, settle, or pay such claim; provided, however, that settlement or full payment of any such claim may be made only with the Indemnifying Party’s consent or, absent such consent, written opinion of the Indemnified Party’s counsel that such claim is meritorious or warrants settlement.

ARTICLE 16

FORCE MAJEURE

16.1              Definition of Force Majeure Event. For the purposes of this Agreement, a “Force Majeure Event” as to a Party means any occurrence, nonoccurrence or set of circumstances that is beyond the reasonable control of such Party and is not caused by such Party’s negligence, lack of due diligence, or failure to follow Prudent Industry Practices, including (without limitation) flood, ice, earthquake, windstorm or eruption; fire; explosion; invasion, riot, civil war, commotion or insurrection; sabotage, terrorism or vandalism; military or usurped power, or act of God or of a public enemy. The term Force Majeure Event shall not include: (i) the inability to meet a Legal Requirement or the change in a

63

Legal Requirement after the date of this Agreement which increases the costs of performance by a Party of its obligations hereunder but which does not preclude or make illegal such performance; (ii) a site-specific strike, walkout, lockout or other labor dispute over employment conditions at the Facility, (but not including any such action or matter as a result of an organizational campaign at the Facility); (iii) equipment failure, unless such equipment failure results directly from another Force Majeure Event; (iv) Seller’s inability to perform its obligations hereunder arising from its lack of ownership of or direct control over the Site or the Project; (v) unavailability of transmission capability, including a Conasauga Line Outage or any Transmission System Constraints; (vi) changes in market conditions that affect the cost or availability of the Facility’s fuel supply or the cost of power from resources other than the Facility; (vii) any event affecting the ability of a Party to provide Natural Gas to the Facility unless such an event affects firm transportation and constitutes a force majeure event under the applicable pipeline tariff, or is the result of an operational flow order that is not directed toward Seller’s failure to comply with the applicable pipeline tariff, provided further that Seller shall be excused from performance only so long as and to the extent that it is unable to reschedule transportation volumes on the unaffected pipelines at no additional cost to Seller; or (viii) failures of contractors, suppliers or vendors (other than fuel suppliers or transporters), unless such failures are caused by an event which would be a Force Majeure Event, if experienced by a Party.

16.2              No Breach or Liability. Either Party shall be excused from performance of its obligations hereunder other than accrued payment obligations and shall not be construed to be in default in respect of such obligations to

64

the extent that and for so long as failure to perform such obligations is due to a Force Majeure Event.

16.3              Capacity and Energy Payments. Buyer’s obligation to make Monthly Capacity Payments shall be excused pro rata to the extent that Seller’s obligations to honor Scheduling Instructions from Buyer are excused as a result of Force Majeure Event claimed by Seller; provided, however, that Seller may continue to receive such capacity and energy payments during a Force Majeure Event so long as it covers Buyer’s Scheduling Instructions in a manner consistent with Section 8.4. Seller must give Buyer written notice of its decision to cover within seven (7) Days of the declaration of the Force Majeure Event. To be valid, this notification shall include a written, irrevocable commitment by Seller to cover Buyer’s Scheduling Instructions for the duration of the Force Majeure Event.

16.4              Mitigation. Following the occurrence of a Force Majeure Event, the affected Party shall:

(i) give the other Party notice thereof, followed by written notice if the first notice is not written, as promptly as possible after such Party becomes aware of such Force Majeure Event, describing the particulars of such Force Majeure Event;

(ii) remedy its inability to perform as soon as reasonably practicable; provided, however, that this Section shall not require the settlement of any non-site specific strike, walkout, lockout or other general labor dispute on terms which, in the sole judgment of the Party involved in the dispute, are contrary to its interest; and

(iii) give the other Party written notice promptly after it determines when it is able to resume performance of its obligations under this Agreement.

65

16.5              Suspension of Performance. The suspension of performance due to a Force Majeure Event shall be of no greater scope and of no longer duration than is required by such Force Majeure Event. No Force Majeure Event shall extend this Agreement beyond its stated Term. If Seller’s ability to deliver Natural Gas to the Facility is restricted by a Force Majeure Event relating to a pipeline, the quantity of Natural Gas that Seller shall be excused from providing shall be calculated as follows:

[***] = the greater of:

(i) [***]

(ii) [***]

Where,

[***]

[***]

16.6              Extended Force Majeure Events.

16.6.1 If a Party has reason to believe that a Force Majeure Event which is preventing the other Party from performing its obligations hereunder will result in a suspension of such performance for a term of six (6) Months or longer (an “Extended Force Majeure Event”), that Party may request that the other Party submit a “Force Majeure Remedy Plan,”

*** Certain information on this page has been omitted and filed separately with the SEC.  Confidential treatment has been requested with respect to the omitted portions.

66

which the other Party shall submit to the requesting Party within thirty (30) Days of the request. If the Party claiming an excuse under this Article 16 has reason to believe that a Force Majeure Event is an Extended Force Majeure Event, it shall notify the other Party promptly and shall submit a Force Majeure Remedy Plan to the other Party within thirty (30) Days thereafter. The Force Majeure Remedy Plan shall set forth a course of repairs, improvements, changes to operations or other actions which should permit the affected Party to perform its obligations under this Agreement as soon as reasonably practicable.

16.6.2 While a Force Majeure Remedy Plan is in effect, the Party prevented from performing its obligations due to the Force Majeure Event shall provide Monthly status reports to the other Party notifying the other Party of the steps which have been taken to remedy the Force Majeure Event and the expected remaining duration of the Party’s inability to perform its obligations.

16.6.3 The Party not prevented from performing its obligations due to the Force Majeure Event may at any time terminate this Agreement effective upon ten (10) Days prior written notice if: (i) the affected Party fails to provide a Force Majeure Remedy Plan as provided for in this Section 16.6; (ii) the affected Party fails to carry out the Force Majeure Remedy Plan in a method reasonably designed to cause that Party to be able to perform its obligations hereunder; or (iii) the affected Party remains unable to perform its obligations hereunder twelve (12) Months following the submission of the Force Majeure Remedy Plan or fifteen (15) Months following notice of the Force Majeure Event pursuant to Section 16.4(i), whichever occurs first. Notwithstanding the foregoing, as long as Seller is able to respond to Scheduling Instructions Scheduling 280 MW or more, Buyer shall not have the right to terminate this Agreement as a result of an Extended Force Majeure Event claimed by Seller.

67

16.6.4 Upon termination of this Agreement as provided in Section 16.6.3, the Parties shall have no further liability or obligation to each other except for any obligation arising prior to the date of such termination.

ARTICLE 17

DEFAULT AND REMEDIES

17.1              Default by Seller. The occurrence of any of the following events shall constitute an Event of Default by Seller:

17.1.1 Any representation or warranty made by Seller herein or in any certificate delivered to Buyer pursuant hereto or by Seller Guarantor in the Seller Guaranty shall prove to be incorrect in any material respect when made, unless Seller shall promptly commence and diligently pursue action to cause such representation or warranty to become true in all material respects and does so within thirty (30) Days after notice thereof has been given to Seller by Buyer (unless such cure is not capable of being effected within such thirty (30) Day period in which case Seller shall have an additional thirty (30) Day period in which to perform such cure) and such cure removes any material adverse effect on Buyer of such representation or warranty having been incorrect.

17.1.2 A court having jurisdiction shall enter: (i) a decree or order for relief in respect of Seller in an involuntary case or proceeding under any applicable Federal or state bankruptcy, insolvency, reorganization or other similar law; or (ii) a decree or order adjudicating Seller bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of Seller under any applicable Federal or state law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of Seller or of any substantial part of its affairs.

68

17.1.3 Seller shall: (i) commence a voluntary case or proceeding under any-applicable Federal or state bankruptcy, insolvency, reorganization or other similar law or any other case or proceeding to be adjudicated a bankrupt or insolvent; (ii) consent to the entry of a decree or order for relief in respect of Seller in any involuntary case or proceeding under any applicable Federal or state bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against it; (iii) file any petition, answer or consent seeking reorganization or relief under any applicable Federal or state law; (iv) consent to the filing of any petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or similar official of Seller or of any substantial part of its property; (v) make an assignment for the benefit of creditors; (vi) admit in writing its inability to generally pay its debts as they become due; or (vii) take any action in furtherance of any of the foregoing.

17.1.4 Seller fails to comply or cause compliance with the Seller Performance Security requirements of Section 7.1 or Seller Guarantor breaches any of its obligations under the Seller Guaranty.

17.1.5 Seller fails to perform or observe any material obligation of Seller under this Agreement, other than those obligations specifically addressed in Section 17.1, which failure materially and adversely affects the ability of Seller or Buyer to perform their respective obligations under this Agreement and continues for a period of thirty (30) Days after written notice thereof from Buyer unless such cure is not capable of being effected within such thirty (30) Day period, in which case Seller shall have an additional thirty (30) Day period in which to perform such cure.

17.1.6 A violation of the requirements of Article 19 through an assignment or

69

transfer of this Agreement or an ownership interest in the Facility or a Change of Control Transaction.

17.1.7 Seller fails to pay Buyer any amount payable by Seller to Buyer (other than amounts in dispute that are not expressly required by this Agreement to be paid) pursuant to this Agreement for fifteen (15) Days after the same shall have become due and payable and Seller fails to cure such failure to pay within fifteen (15) Days after receipt of written demand therefore from Buyer.

17.1.8 Except for the circumstances addressed by Section 11.7.2, the Availability Percentage for any twelve (12) consecutive Months during which eight hundred (800) or more MWh are Scheduled is below sixty percent (60%); provided, however, that Seller may, within fifteen (15) Days after the end of such twelve (12) Month period, submit a cure plan that is reasonably expected to resolve the cause of the unsatisfactory Availability Percentage as soon as practicable, but in no event later than ninety (90) Days from the end of such twelve (12)-Month period. If Seller fails to submit such a cure plan in a timely manner or fails to diligently pursue implementation of the cure plan, or if the unsatisfactory Availability Percentage is not, in fact, cured by the end of the ninety (90) Day period, and remains uncured for twelve (12) consecutive Months, then Buyer shall have the right to declare an Event of Default. The cause of the unsatisfactory Availability Percentage shall be deemed cured if the average Monthly Availability Percentage determined prospectively are at least sixty percent (60%). For the purposes of this Section 17.1.8, the “Availability Percentage” shall mean the sum of the MW Scheduled and MW Delivered which sum is then divided by the MW Scheduled.

17.1.9 Except for the circumstances addressed by Section 11.7.2, the demonstrated capability of the Facility determined pursuant to a Performance Test at any time

70

after the Commercial Operation Date is below two hundred and eighty (280) MW, and Seller fails to promptly commence and diligently pursue or cause others to pursue action to cure and which action cures such inadequate demonstrated capacity within thirty (30) Days (unless such cure is not capable of being effected within such thirty (30) Day period, in which case Seller shall have an additional thirty (30) Day period in which to cause such cure). Seller shall submit a plan for curing such inadequate demonstrated capability as soon as reasonably practicable, but in no event more than fifteen (15) Days after the Performance Test revealing such inadequate demonstrated capability. If Seller fails to deliver the cure plan within such fifteen (15) Day period or to cause implementation of the cure plan (including implementation of such actions as Buyer may reasonably request), Buyer shall have the right to declare an Event of Default.

17.1.10 Seller breaches its obligations under Sections 5.1.1 and 5.1.6 to the extent that the Facility is Available, and such breach continues for more than two (2) hours after Buyer provides Seller with written notice of such breach; provided, however, that, subject to Section 17.3.4, such a breach shall not be an Event of Default so long as (a) Seller believes in good faith that either the Facility is Unavailable or Seller is not obligated to comply with Buyer’s Schedule, and (b) Seller provides Buyer with prompt written notice of the Unavailability of the Facility or the reasons why Buyer’s Schedules do not comply with Section 13.1.

17.2              Default by Buyer. The occurrence of any of the following events shall constitute an Event of Default by Buyer:

17.2.1 Buyer fails to pay any amount payable by Buyer to Seller (other than amounts in dispute that are not expressly required by this Agreement to be paid) pursuant to this Agreement for fifteen (15) Days after the same shall have become due and payable and Buyer fails to cure such failure to pay within fifteen (15) Days after receipt of written demand therefor

71

from Seller.

17.2.2 Buyer fails to perform or observe any material obligation of Buyer under this Agreement, other than those obligations included in this Section 17.2, which failure materially and adversely affects the ability of Seller or Buyer to perform their respective obligations under this Agreement and continues for a period of thirty (30) Days after written notice thereof from Seller (unless such cure is not capable of being effected within such thirty (30) Day period, in which case Buyer shall have an additional thirty (30) Day period in which to perform such cure.)

17.2.3 Any representation or warranty made by Buyer herein or in any certificate delivered to Seller pursuant hereto or by Buyer Guarantor (if applicable) in the Buyer Guaranty shall prove to be incorrect in any material respect when made, unless Buyer shall promptly commence and diligently pursue action to cause such representation or warranty to become true in all material respects and does so within thirty (30) Days after notice thereof has been given to Buyer by Seller (unless such cure is not capable of being effected within such thirty (30) Day period in which case Buyer shall have an additional thirty (30) Day period in which to perform such cure) and such cure removes any material adverse effect on Seller of such representation or warranty having been incorrect.

17.2.4      A court having jurisdiction shall enter: (i) a decree or order for relief in respect of Buyer in an involuntary case or proceeding under any applicable Federal or state bankruptcy, insolvency, reorganization or other similar law; or (ii) a decree or order adjudicating Buyer bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of Buyer under any applicable Federal or state law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other

72

similar official of Buyer or of any substantial part of its affairs.

17.2.5 Buyer shall: (i) commence a voluntary case or proceeding under any applicable Federal or state bankruptcy, insolvency, reorganization or other similar law or any other case or proceeding to be adjudicated a bankrupt or insolvent; (ii) consent to the entry of a decree or order for relief in respect of Buyer in any involuntary case or proceeding under any applicable Federal or state bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against it; (iii) file any petition, answer or consent seeking reorganization or relief under any applicable Federal or state law; (iv) consent to the filing of any petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or similar official of Buyer or of any substantial part of its property; (v) make an assignment for the benefit of creditors; (vi) admit in writing its inability to generally pay its debts as they become due; or (vii) take any action in furtherance of any of the foregoing.

17.2.6 Buyer fails to comply or cause compliance with the Buyer Performance Security requirements of Section 7.2 or Buyer Guarantor (if applicable) breaches any of its obligations under the Buyer Guaranty.

17.3 Remedies.

17.3.1 If an Event of Default occurs at any time during the Term, the non-defaulting Party (the “Non-Defaulting Party”) may, for so long as the Event of Default is continuing, subject to the provisions of Article 20, take one or more of the following actions: (i) establish a date (which date shall be between five (5) and ten (10) Business Days after the Non-Defaulting Party delivers written notice of such date to the Defaulting Party) on which this

73

Agreement shall terminate (the “Early Termination Date”), (ii) proceed by appropriate proceedings in accordance with this Agreement at law, in equity or otherwise, to protect and enforce its right to damages (actual or liquidated) or, where the Event of Default is one other than the failure to pay money, equitable relief, including specific performance, and (iii) immediately cease performance or withhold any payments, or both, due in respect of this Agreement.

17.3.2 If an Early Termination Date has been established, the Non-Defaulting Party shall in good faith calculate its Gains, Losses and Costs resulting from the termination of this Agreement, aggregate such Gains, Losses and Costs into a single net amount (the “Termination Payment”), and then notify the defaulting Party (the “Defaulting Party”). The Gains, Losses and Costs shall be determined by comparing the cost under this Agreement of the capacity and energy that would be available under this Agreement for the remainder of the Term had this Agreement not been terminated to the market price of capacity and energy of equivalent reliability and Scheduling flexibility for the remaining Term (had this Agreement not been terminated). To ascertain such market price, the Non-Defaulting Party may consider, among other evidence, the settlement prices of NYMEX energy futures contracts, quotations from leading dealers in energy and gas swap contracts, offers for replacement capacity and energy made by bona fide third-parties (including offers received by the Non-Defaulting Party in response to any request for proposals for capacity and energy contracts), all adjusted for the length of the remaining Term (had this Agreement not been terminated) and differences in locational basis, reliability, scheduling flexibility and any other considerations affecting value. Neither Party shall be required to enter into replacement transactions in order to determine the Termination Payment. If the Non-Defaulting Party’s aggregate Losses and Costs exceed its aggregate Gains, the Defaulting Party shall, unless it disagrees with such Termination Payment

74

calculation, within fifteen (15) Business Days of receipt of such notice, pay the net amount to the Non-Defaulting Party, which amount shall bear interest at the Interest Rate from the Early Termination Date until paid. If the Non-Defaulting Party’s aggregate Gains exceed its aggregate Losses and Costs, if any, resulting from the termination of this Agreement, the Non-Defaulting Party may retain such Gains unless the Non-Defaulting Party disagrees with such Termination Payment calculation. If the Defaulting Party disagrees with the calculation of the Termination Payment, the issue shall be resolved pursuant to the provisions of Article 20 applicable to Termination Payment disputes, and the resulting Termination Payment shall be due and payable within three (3) Business Days after the award. As used in this Section 17.3.2: (i) ”Costs” shall mean, brokerage fees, commissions and other similar transaction costs and expenses reasonably incurred by such Party either in terminating any agreement which it has entered into to fulfill its obligations hereunder or entering into new agreements which replace this Agreement, and attorneys’ fees, if any, incurred in connection with enforcing its rights under this Agreement; (ii) ”Gains” shall mean, an amount equal to the economic benefit determined on a ▇▇▇▇ to market basis (exclusive of Costs), if any, to it resulting from the termination of its obligations with respect to this Agreement; and (iii) ”Losses” shall mean an amount equal to the economic loss determined on a ▇▇▇▇ to market basis (exclusive of Costs), if any, to it resulting from the termination of its obligations with respect to this Agreement.

17.3.3 Notwithstanding any other provision of this Agreement, if Buyer or Seller fails to pay to the other Party any amounts when due, the Aggrieved Party, in addition to any other rights and remedies under this Agreement, shall have the right to suspend performance, following five (5) Business Days written notice to the other Party, until such amounts plus interest at the Interest Rate have been paid. A Party’s right to damages or other relief from a

75

breach commences as of the first Day of the breach and accrues thereafter until cured, without regard to whether such breach results in an Event of Default or termination, and following the expiration of any applicable cure period, each Party shall have all rights and remedies available at law and equity, all of which rights and remedies shall be cumulative and nonexclusive subject to and to the extent permitted by law and Section 17.5; provided, however, that no right to damages or other relief from a breach shall exist with respect to any breach that is cured within the applicable cure period.

17.3.4 If Seller sells energy to a third party during periods in which Seller believes in good faith that Seller was not obligated to comply with Buyer’s Schedules, and it is subsequently determined that Seller was, in fact, obligated to meet such Schedules, Seller shall reimburse Buyer for the Incremental Replacement Costs incurred by Buyer in replacing any Scheduled energy that Seller failed to deliver.

17.4              Rights of Specific Performance. In the case of an Event of Default, the Parties recognize that any remedy at law may be inadequate because the actual damages of the Non-Defaulting Party may exceed the amount of any guaranty or other collateral available to the Non-Defaulting Party. The Parties agree that in such an event, the Non-Defaulting Party shall be entitled to pursue an action for specific performance and the defaulting Party waives all of its rights to assert as a defense to such action that the Non-Defaulting Party’s remedy at law is adequate. In addition, in the event of Seller’s failure to comply with the requirements of Section 11.1.1, the Parties recognize and agree that if the interests of Buyer are harmed as a result of such noncompliance, Buyer’s remedy at law will be inadequate and Buyer shall be entitled to pursue an action for specific performance, in which

76

case, Seller waives all of its rights to assert as a defense to such action for specific performance that Buyer’s remedy at law is adequate.

17.5 Limitation of Remedies, Liability and Damages. THE PARTIES CONFIRM THAT THE EXPRESS REMEDIES AND MEASURES OF DAMAGES PROVIDED IN THIS AGREEMENT SATISFY THE ESSENTIAL PURPOSES HEREOF FOR BREACH OF ANY PROVISION FOR WHICH AN EXPRESS REMEDY OR MEASURE OF DAMAGES IS PROVIDED, SUCH EXPRESS REMEDY OR MEASURE OF DAMAGES SHALL BE THE SOLE AND EXCLUSIVE REMEDY, THE OBLIGOR’S LIABILITY SHALL BE LIMITED AS SET FORTH IN SUCH PROVISION AND ALL OTHER REMEDIES OR DAMAGES AT LAW OR IN EQUITY ARE WAIVED. IF NO REMEDY OR MEASURE OF DAMAGES IS EXPRESSLY HEREIN PROVIDED, THE OBLIGOR’S LIABILITY SHALL BE LIMITED TO DIRECT ACTUAL DAMAGES ONLY, SUCH DIRECT ACTUAL DAMAGES SHALL BE THE SOLE AND EXCLUSIVE REMEDY AND ALL OTHER REMEDIES OR DAMAGES AT LAW OR IN EQUITY ARE WAIVED. UNLESS EXPRESSLY HEREIN PROVIDED, AND EXCEPT FOR THE PAYMENT OF LIQUIDATED DAMAGES, REPLACEMENT COSTS OR INCREMENTAL REPLACEMENT COSTS SPECIFIED HEREIN, NEITHER PARTY SHALL BE LIABLE FOR CONSEQUENTIAL, INCIDENTAL, PUNITIVE, EXEMPLARY OR INDIRECT DAMAGES, LOST PROFITS OR OTHER BUSINESS INTERRUPTION DAMAGES, BY STATUTE, IN TORT OR CONTRACT, UNDER ANY INDEMNITY PROVISION OR OTHERWISE. IT IS THE INTENT OF THE PARTIES THAT THE LIMITATIONS HEREIN IMPOSED ON REMEDIES AND THE MEASURE OF DAMAGES BE WITHOUT REGARD TO THE CAUSE OR CAUSES RELATED THERETO, INCLUDING THE NEGLIGENCE OF ANY

77

PARTY, WHETHER SUCH NEGLIGENCE BE SOLE, JOINT OR CONCURRENT, OR ACTIVE OR PASSIVE. TO THE EXTENT ANY DAMAGES REQUIRED TO BE PAID HEREUNDER ARE LIQUIDATED, THE PARTIES ACKNOWLEDGE THAT THE DAMAGES ARE DIFFICULT OR IMPOSSIBLE TO DETERMINE, OTHERWISE OBTAINING AN ADEQUATE REMEDY IS INCONVENIENT AND THE LIQUIDATED DAMAGES DO NOT CONSTITUTE A PENALTY AND ARE A REASONABLE APPROXIMATION OF THE HARM OR LOSS. NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, IN NO EVENT SHALL BUYER’S LIABILITY TO SELLER FOR A TERMINATION PAYMENT UNDER THIS AGREEMENT EXCEED AN AMOUNT EQUAL TO THE SUM OF ANY AMOUNTS THEN OWED BY BUYER HEREUNDER PLUS THE TOTAL OF ALL REMAINING MONTHLY CAPACITY PAYMENTS FOLLOWING TERMINATION THAT WOULD HAVE BEEN PAYABLE TO SELLER UNDER THIS AGREEMENT HAD THE AGREEMENT REMAINED IN EFFECT THROUGH THE END OF THE TERM.

17.6 Duty to Mitigate. Notwithstanding any other provision of this Agreement, each Party has a duty to mitigate damages and covenants that it will use commercially reasonable efforts to minimize any damages it may incur as a result of the other Party’s performance or non-performance.

ARTICLE 18

CHANGE OF LAW

18.1              Change of Law.

18.1.1 A “Change of Law” means a change in a Legal Requirement constituting a

78

new environmental or tax law or regulation or a new interpretation of such law or regulation, which change is enacted after the execution date of this Agreement and that is generally applicable to facilities that are similar to and similarly situated as the Facility. The provisions of Sections 18.1.3 and 18.1.4 shall not apply to a Change of Law that has been reflected in Buyer’s capacity and/or energy payments through the previous operation of those sections.

18.1.2 The Parties acknowledge that, except as provided in Sections 18.1.3 and 18.1.4, the capacity and energy payments made by Buyer shall not be altered as a result of a Change of Law that causes either Party to incur additional costs or realize savings in carrying out its obligations under this Agreement.

18.1.3 If a Change of Law (or cumulative Changes of Law) in the aggregate causes Seller to incur additional costs that are projected to increase Seller’s annual costs of carrying out its obligations under this Agreement above [***] (the “Threshold Amount”) per year, such additional costs in excess of the Threshold Amount may be passed through to Buyer; provided, however, that such Threshold Amount shall be increased to [***] in any case where a Change of Law affects the cost of electric generation at the Facility but not at other facilities similar to and similarly situated as the Facility. Seller shall notify Buyer of the Change of Law and the Seller’s proposed increase in capacity or energy payments under this Agreement. For purposes of calculating the annual cost increase associated with capitalized additions or modifications to the Facility (determined in accordance with generally accepted accounting principles), the Parties will at that time establish an appropriate levelized fixed charge rate (incorporating an after-tax return of [***] for application to the original capital cost of such additions or modifications.

with the identified addition or modification, including depreciation, carrying costs, and any other cost or expense item related to capital investments. Upon receipt of such notice, Buyer will within thirty (30) Days make a good faith determination whether Seller’s proposed price increase results from a Change of Law as specified in this Agreement. In the event Buyer concurs that the proposed price increase results from a Change of Law, the proposed increased rates will take effect consistent with the timing of the additional cost incurrence (but in no event earlier than the end of the thirty (30) Day period). If Buyer disagrees with Seller’s determination, such disagreement shall be resolved pursuant to the provisions of Article 20 applicable to Change of Law disputes. The results of any such dispute resolution procedures shall be retroactively applied (with interest at the Interest Rate) to reflect any such increase in Seller’s costs.

18.1.4 If a Change of Law (or cumulative Changes of Law) in the aggregate causes Seller to incur a reduction in costs that are projected to decrease Seller’s annual costs of carrying out its obligations under this Agreement by more than [***] per year, such reduction in excess of such amount will be passed through to Buyer. Buyer may notify Seller of the Change of Law and Buyer’s proposed decrease in capacity or energy payments under this Agreement. Upon receipt of such notice, Seller will within thirty (30) Days make a good faith determination whether Buyer’s proposed price decrease results from a Change of Law as specified in this Agreement. In the event that Seller concurs that the proposed price decrease results from a Change of Law, the proposed decreased rates will take effect consistent with the timing of the additional cost reduction (but in no event earlier than the end of the thirty (30) Day period). If Seller disagrees with Buyer’s determination, such disagreement shall be resolved pursuant to the provisions of Article 20 applicable to Change of Law disputes. The result of any such dispute resolution procedures shall

be retroactively applied (with interest at the Interest Rate) to reflect any such reduction in Seller’s costs.

18.1.5 Under no circumstances can Buyer’s determination regarding the applicability of the Change of Law provision to a proposed price increase or Seller’s determination regarding the applicability of the Change of Law provision to a proposed price decrease constitute an Event of Default under Article 17 of this Agreement.

18.2              NOX Emissions. Buyer shall supply Seller with the actual number of allowances required by any Governmental Authority or Consent for emission of nitrogen oxides (“NOX Allowances”) for energy purchased from Seller and delivered from the Facility pursuant to this Agreement, subject to the following limitations:

(i)                         Seller shall be first required to use, at no cost to Buyer, all NOX Allowances Seller or other Persons are granted with respect to the Facility through any type of state or Federal set-aside program during the Term; and

(ii)                      Buyer shall not be required to provide NOX Allowances that are needed due to the Facility exceeding a NOX emission rate of 0.011 lbs/MMBtu.

18.3              No Dedication. No undertaking by Seller under this Agreement is intended to constitute the dedication of the Facility or any part thereof to the public or affect the status of Seller as an independent entity and not a public utility or public service company.

If the Party whose consent is requested determines not to grant any requested consent it shall, within fifteen (15) Days after of the receipt of a written request therefore, provide the requesting Party with a written explanation for the reasons for such denial, including, if applicable, a detailed explanation as to why the assignment, transfer or Change of Control Transaction will cause a Material Adverse Effect on such Party, and in the absence of any such notice, the requested consent shall be deemed to have been granted.

19.4.2 An assignor of this Agreement shall be entitled to a written release from any and all liability hereunder provided (i) such assignor requests such release in writing, (ii) the assignee assumes all of the assignor’s obligations and liability under this Agreement, and (iii) any consent required pursuant to Section 19.1 has been granted.
