Whenever, in the reasonable opinion of Owner, Contractor has failed to take sufficient precautions for the safety of the public or the protection of the Facility, the Systems, the Site or property adjacent thereto, creating, in the reasonable opinion of Owner, an emergency requiring immediate action, then Owner, after having given reasonable prior notice to Contractor (except in the case of an emergency, in which event notice may be given after the fact), may cause such sufficient precautions to be taken or provide such protection. The cost and expense of taking or provision of any such precautionary actions by Owner or its agents will be treated as an Allocable Cost pursuant to Section 11.5. Owner’s taking any such precautionary actions will not relieve Contractor of its obligations under this Agreement or Applicable Laws or constitute a waiver of any of Owner’s rights or a mitigation or diminution of any of Contractor’s obligations under this Agreement. In addition to, and to further describe Contractor’s safety obligations, the following are understood and agreed:

6.8.1 Contractor Responsibility.�� Contractor agrees to employ the appropriate means, methods, techniques, sequences, or procedures of construction, and to establish or undertake safety precautions/programs in accomplishing the Work.

Contractor shall furnish Owner with a copy of its SWPPP for each Site before commencing the Work at that Site.

6.8.12 Operating Environment. Contractor must assure that its employees and Subcontractors work safely in the environment of an electric utility.

6.8.12.1 Generating Sites. Within power plants, there are fire, high-pressure steam, high-voltage electricity, and chemicals. All require careful attention to those hazards and extreme care to assure that Contractor’s operation does not damage or interfere with the plant operation.

6.8.12.2 Electrical System. Within substations, and overhead and underground transmission lines, extremely high-voltage electricity requires the strict compliance with OSHA and Owner’s safety regulations.

6.9 Operating Utilities Interface. Owner will, in accordance with the schedule agreed to by Owner pursuant to Section 8.1, make such utilities available to Contractor as described in Exhibit 1.

6.10 Owner’s Right to Inspect, Stop and Re-Perform Work.

6.10.1 Owner’s Right to Attend Contractor Inspections. Owner will have the option of being present at all inspections and testing on or off the Site, and, in the event that the progress and quality of the Work are not proceeding in accordance with Contract Documents or the Approved Project Schedule, will be entitled to make recommendations to Contractor or any Subcontractor for the purpose of remedying such deficiencies. No inspection observed or performed or failed to be observed or performed by Owner will be deemed a waiver of any of Contractor’s obligations or be construed as an approval or acceptance of the Work.

6.10.2 Inspection and Re-Performance. Owner will have the right to have access to and inspect the Work, wherever located and at any stage of completion. Owner may reject any Work that does not comply with the Contract Documents. If Owner’s inspection reveals any such non-compliance or any other defects in any portion of Work, then Contractor will promptly correct all such defective Work and the cost of such correction shall be treated as an Allocable Cost under Section 11.5. If Contractor fails to initiate correction of the defective Work within five (5) calendar days of Owner’s notice, Owner may, without prejudice to any other remedy Owner may have under this Agreement, correct such defective Work. Owner’s correction of such defective Work will not relieve Contractor of its obligations under this Agreement. All costs and expenses related to such actions of Owner will be treated as Allocable Costs, and Contractor will promptly reimburse Owner for all such amounts if and to the extent such costs are to be borne by Contractor pursuant to Section 11.5.

7. PERFORMANCE GUARANTEES

Contractor guarantees that the Systems will meet the performance guarantee requirements below, as further described in Exhibit 6 (the “Performance Guarantees”).

7.1 Input Guarantees for FGD Systems. The following input guarantees as further set forth in Exhibit 6 (“Input Guarantees”) apply to the FGD Systems:

7.1.1 Guaranteed Consumption Levels. The guaranteed consumption levels and related engineering design margins (the “Engineering Design

Margins”) are set forth in Exhibit 6 for consumption of auxiliary power, limestone, and makeup water.

7.1.2 Consumption Within Engineering Design Margins. In cases where the actual consumption exceeds the guarantee, but is within the Engineering Design Margins as established pursuant to Section 7.1.1, then, as Owner’s sole and exclusive remedy, the liquidated damages for excess consumption listed below shall accrue and be treated as Guarantee Costs under Section 11.3.

7.1.3 Consumption Outside Engineering Design Margins. In cases where the actual consumption exceeds both the guarantee and the Engineering Design Margins, then the liquidated damages for excess consumption shall apply plus Contractor shall perform all Work necessary to satisfy the Engineering Design Margins and re-test the Systems until the testing verifies that consumption is within the Engineering Design Margins as established pursuant to Section 7.1.1. The costs of such work and re-testing shall be treated as Guarantee Costs pursuant to Section 11.3. Once a System is placed in service and the actual operating parameters are established, the Engineering Design Margin shall be adjusted by agreement of the Parties to reflect the actual operating requirements and to allow reasonable operating capacity margins in accordance with Prudent Utility Practices and Prudent Electrical Practices.

7.1.4 Liquidated Damages for Input Guarantees for FGD Systems. Liquidated damages shall be assessed against Contractor for exceeding guaranteed consumption levels for FGD Systems as follows:

7.1.4.1 Power Consumption. Liquidated damages of $1,370 per kW shall apply for every kW in excess of the guaranteed power consumption (excluding fan).

7.1.4.2 Make-Up Water Consumption. Liquidated damages of $4,000 per gallon/minute shall apply for every gallon/minute in excess of the guaranteed water consumption.

7.1.4.3 Limestone Consumption. Liquidated damages of $1,000,000 per ton/hr for each ton/hr in excess of the guaranteed limestone consumption.

7.2 Output Guarantees for FGD Systems.

7.2.1 List of Output Guarantees. The following output guarantees as further set forth in Exhibit 6 (“Output Guarantees”) shall apply to the FGD Systems:

7.2.1.7 Wastewater Effluent Quality as provided in Section 1.1.13 of Exhibit 6, and Item 6 of Exhibit 8C.

7.2.2 Correction by Contractor. For each of the Output Guarantees for a FGD System, System output shall satisfy the guaranteed value as a minimum. If during testing the guaranteed value is not met, Contractor shall correct the Work, repair or replace the affected parts or systems and re-test until the guaranteed values are achieved, except that for Mercury Removal the provisions of Section 7.2.3 shall apply. The costs of such correction and re-testing (and any payments due from Contractor pursuant to Section 7.2.3 to the extent not collected by Contractor from the FGD Subcontractor) shall be treated as Guarantee Costs pursuant to Section 11.3.

7.2.3 Mercury Removal. Mercury Removal will be tested for during Performance Test PA as described in Exhibit 6. In the event that the actual Mercury Removal is less than the guaranteed Mercury Removal, Owner shall asses Contractor $1,000,000 per each FGD System where the performance guarantee was not achieved, and the Mercury Removal criteria for successful completion shall be deemed to have occurred as of the date of the Performance Test PA. Such assessment shall be treated in accordance with Article 7.2.2. For a period of ninety (90) days after the Performance Test PA, Contractor shall be given the opportunity to modify and re-test the system in order to achieve the Mercury Removal performance guarantee. If the performance guarantee is met after re-testing by Contractor, within the ninety (90) day cure period, Owner shall return to Contractor the above-referenced payments if such amounts were paid to Owner pursuant to Article 7.2.2 for each FGD System where the performance guarantee was achieved. After the ninety (90) day cure period has expired and the performance guarantee is not met after re-testing by the Contractor, Owner, as a performance liquidated damage, shall retain the above-referenced payments pursuant to Article 7.2.2 for each FGD System where the performance guarantee was not achieved. During the ninety (90) day cure period, the Contractor shall

have access to the equipment to implement potential remedies, and the FGD shall be operated in a reasonable manner to support Contractor’s efforts.

7.7 Performance Testing.

7.7.1 Performance Testing . After the occurrence of Mechanical Completion for each System, and after the “Ready for Flue Gas to Scrubber” milestone in Exhibit 15 is achieved, Contractor will start-up the System. Once Contractor has started a System, Owner will operate the corresponding Unit or Units continuously for ninety (90) days (the “FGD Tuning Period”) during which Contractor and its FGD Subcontractor will be afforded an opportunity to tune and maximize the operation of the System. The FGD Tuning Period shall include at least twenty (20) days, scheduled at Contractor’s reasonable requirement, during which the corresponding Unit or Units are operated at or near full load. Contractor shall notify Owner when each System is ready to be tested (such notice, the “Testing-Ready Notice”). Contractor will provide notice to Owner of

Performance Test PA no later than fifteen (15) days prior to the then-scheduled date of Provisional Acceptance for the System to be tested. Contractor will provide notice to Owner of Performance Test 1 no later than fifteen (15) days prior to the then-scheduled date of Substantial Completion for the System to be tested. Contractor will perform the tests on each System as are described in Exhibit 6, which tests are designed to demonstrate whether the System achieves the Performance Guarantees (the “Performance Tests”); provided, that the results of such tests will be adjusted, in a manner agreed to by the Parties, to the design conditions set forth in Exhibits 1 and 6 and in accordance with correction curves prepared by Contractor in accordance with Exhibit 6 and approved by Owner. Owner has the right to witness all occurrences of Performance Test 1 and Performance Test PA. If a System fails to meet any of the Performance Guarantees during such Performance Test PA or Performance Test 1, then Contractor will immediately take such actions as are required to correct the Work so as to meet the Performance Guarantees, and notify Owner when such System is ready to be re-tested. Contractor will use all reasonable efforts to complete the re-performed Performance Test 1 and Performance Test PA on such System within thirty (30) days. The costs of such correction and re-testing shall be treated as Guarantee Costs pursuant to Section 11.3. If a System fails to satisfy the requirements at Performance Test 2 within the first 270 days of testing, any costs of retesting and correction that are not due to failure of the Owner to operate the System in accordance with Section 1.2 of Exhibit 6 and the manuals provided by Contractor pursuant to Section 6.5.6, shall be treated as Guarantee Costs. Owner shall afford the Contractor opportunity to test at least two FGD Systems before July 2011. Provided that the Performance Guarantees as set forth in Exhibit 6 are met during these tests, and the Performance Tests have not been performed on a maximum of two FGD Systems, the Systems not tested shall be deemed Substantially Complete.

7.8 Concurrent Obligations. The Performance Tests listed in Sections 2.1.5 of Exhibit 6 shall be performed concurrently. If Contractor’s performance of such Performance Tests on a System reveals that such System is not capable of concurrently passing such Performance Tests, then Contractor will immediately and continuously take all measures that are necessary to cause such System to pass such Performance Tests concurrently; provided, that such measures must meet the standards set forth in Article 15. The cost of taking such measures, including without limitation all additional costs of labor, equipment, supplies, tools, non-consumable chemicals and materials shall be treated as Guarantee Costs under Section 11.3.

8. PROJECT SCHEDULE; SCHEDULE GUARANTEES

8.1 Project Schedule. Attached as Exhibit 15 is the “Draft Project Schedule”. Contractor has used its best efforts to schedule all work that requires a Unit to be taken out of service during Owner’s planned outages excepting for “tie-in” outages where Contractor’s obligation is to use reasonable efforts to schedule those outages. The Parties shall agree on the Approved Project Schedule within thirty (30) days of execution of this Agreement. Once the Approved Project Schedule is agreed, it shall replace and

govern over the Draft Project Schedule. The “Approved Project Schedule” contains an integrated detailed engineering, procurement, fabrication, delivery, construction and startup schedule of the Work and the interface activities of Owner’s Separate Contractors and specifies the Guaranteed Provisional Acceptance Dates for the Work included in each System, the Guaranteed Final Completion Date of the Work included in each Facility and all Scheduled Outage Periods, and meets the following conditions:

8.1.1 Guaranteed Provisional Acceptance Date. The Work necessary for and included in the milestone identified in Exhibit 15 as “Ready for Flue Gas to Scrubber” for each FGD System at each Facility shall be completed before 23:59 December 31, 2009, and the Guaranteed Provisional Acceptance Date for each FGD System shall be a date not later than one hundred five (105) days after the first day of the Scheduled Outage Period set forth in the Approved Project Schedule for the final tie-in outage for that System.

8.1.2 Conditions for Outages. The start dates, end dates, and duration of outages (defined as calendar days from 07:00 on the start date of the outage until 23:59 on the end date of the outage) are subject to Owner’s approval and shall meet the following conditions:

8.1.2.1 Final tie-in outages for each Unit for Work on an FGD System will have a maximum duration of fifteen (15) days;

8.1.2.2 Electrical tie-in outages per Unit will occur in March 2009 and have a maximum duration of five (5) days; and

8.1.2.3 The start dates, end dates, and duration of all other outages, shall be as agreed by Owner with a minimum of six (6) months advance notice to Owner from Contractor.

8.1.3 Outage Start and End Dates. The start and end dates of all outages will be mutually agreed between the Parties. Contractor shall be flexible and work with the Owner towards agreeing on the start and end dates of outages.

8.1.4 Blank.

8.1.5 Concurrent Outages. Except as set forth in this Section 8.1.5, Contractor shall not plan an outage for any Unit at Morgantown or Chalk Point for a time when any other Unit at the same Facility is also out of service for a planned outage by Owner or Contractor. In the specific case of Chalk Point Owner shall allow one concurrent outage, prior to the tie-in outage, for a time and duration to be mutually agreed by the Parties. Contractor shall not schedule an outage for any Unit at Dickerson, if two other Units at Dickerson are also out of service for a planned outage by Owner or Contractor. Owner shall provide six (6) months advance notice of outages planned by Owner. Contractor shall provide six (6) months advance notice of outages planned by Contractor that are not in or in accordance with the Approved Project Schedule.

8.1.6 Immovable Milestones. There shall be no change to the following milestones in Exhibit 15:

8.1.6.1 Provisional Acceptance for each FGD System shall occur not later than one hundred five (105) days after the first day of the last Scheduled Outage Period set forth in the Approved Project Schedule for the final tie-in outage for that System, and Substantial Completion for each FGD System shall occur not later than ninety (90) days after the date of Provisional Acceptance for that System;

8.1.6.2 Owner permitting completion and construction full release shall occur not later than September 1, 2007;

8.1.6.3 Required dates for operating utilities interface as described in Exhibit 15;

8.1.6.4 Permitting documents submission date as described in Section 6.2.3.2;

8.1.6.5 The Guaranteed Provisional Acceptance Date as set forth in 8.1.1;

8.1.6.6 Owner’s schedule commitments as set forth in Section 5.3;

8.1.6.7 With respect to each FGD System, the Work included in the milestone identified as “Ready for Flue Gas to Scrubber” in Exhibit 15 shall be completed not later than December 31, 2009.

8.2 Schedule Guarantee. As further provided in this Section 8.2, liquidated damages will accrue for certain extended and unplanned outages, and for delay in achieving any Guaranteed Provisional Acceptance Date, the Guaranteed Substantial Completion Date, or Guaranteed Final Completion Date. Such liquidated damages shall be treated as Guarantee Costs pursuant to Section 11.3.

8.2.1 Work Progress and Completion.

8.2.1.1 General. Contractor will schedule, report and perform the Work according to the Approved Project Schedule. Contractor will provide Owner with a Progress Report on the fifteenth (15th) day of each month during the performance of the Work.

8.2.1.2 Maximum Outage Period. Contractor acknowledges that Owner will incur significant damages and liabilities if any of the Units is taken out of operation for any period longer than the Scheduled Outage Period for such Unit (as will be reflected in the Approved Project

Schedule). Accordingly, all Work that must be performed while a Unit is out of operation will be performed by Contractor during normal maintenance outages scheduled by Owner or during the Scheduled Outage Period for such Unit. Subject only to adjustment by Change Order, the Contractor’s exact compliance with the Scheduled Outage Period set forth in the Approved Project Schedule is crucial to Owner’s business and Contractor has planned, organized and coordinated the Work to fully and exactly comply with such Scheduled Outage Period. Because of the significant economic harm that Owner will suffer if the Contractor does not comply with the Scheduled Outage Period, Owner and Contractor agree that if, during an outage, Contractor is not performing the Work in accordance with the time limits for a Scheduled Outage Period and Owner can reasonably deduce, during the outage, that Contractor will not complete the Work necessary within the Scheduled Outage Period, then Owner may utilize separate contractors to perform all or part of the Work necessary to complete such Work within the Scheduled Outage Period. Liquidated damages for such losses shall accrue for each day that the Contractor does not start and finish the work in exact accordance with the Scheduled Outage Period (such payment with respect to each Unit, the “Excessive Outage Payments”) in the following amounts:

Morgantown; $125,000 per Unit per day

Dickerson; $70,000 per Unit per day

Chalk Point; $100,000 per Unit per day

Owner shall use its best efforts to avoid interference with the Contractor’s Work by the Owner and Owner’s Separate Contractors during the Scheduled Outage Period. Contractor understands and agrees that it shall not interfere with and shall cooperate with the Owner and Owner’s Separate Contractors at the Project Site to fully perform the Work with no or minimal impact to any other party.

8.2.1.2.1 Amounts Reasonable. The Parties agree that the terms, conditions and amounts fixed as liquidated damages pursuant to Section 8.2.1.2 for Excessive Outage Payments are reasonable, considering the actual losses that Owner will incur if the outage of a Unit exceeds the Scheduled Outage Period for such Unit. The amounts of these liquidated damages are agreed upon and fixed hereunder by the Parties because of the difficulty of ascertaining the exact amount of losses that Owner will actually incur in such event, and the Parties agree that such amounts are a reasonable estimate of Owner’s probable loss (and are not a penalty) and that such amounts will be applicable regardless of the actual losses incurred by Owner.

8.2.1.2.2 Bonus for Early Completion. If the Contractor finishes its Work during an outage before the end date of the Scheduled Outage Period, then for each day Owner is able to generate power from the affected Unit Contractor shall receive a bonus as follows:

Morgantown: $ 35,000 per Unit per day

Dickerson: $15,000 per Unit per day

Chalk Point: $25,000 per Unit per day

8.2.1.2.3 Payment of Excessive Outage Payments. Owner will invoice Contractor for any Excessive Outage Payments due under Section 8.2.1.2 on a monthly basis, and Contractor will be assessed the undisputed portion of each such invoice in full within thirty (30) calendar days of its receipt. If, subject to Section 11.3, an undisputed amount remains unpaid for more than five (5) days after receipt of notice from Owner that the amount is overdue, Owner may deduct any such amounts due as Excessive Outage Payments from any unpaid amounts owed by Owner to Contractor under this Agreement.

8.2.2 Guaranteed Provisional Acceptance Date. Contractor guarantees that Provisional Acceptance of each of the Systems will occur on or before the “Guaranteed Provisional Acceptance Date” for each System as set forth in the Approved Project Schedule, subject only to adjustment by Change Order pursuant to Article 19 of this Agreement.

8.2.3 Late Provisional Acceptance Payments. If Provisional Acceptance of a System does not occur on or before the Guaranteed Provisional Acceptance Date for such System, as adjusted by Change Order pursuant to the provisions of this Agreement, liquidated damages shall accrue in the amounts provided below (“Late Provisional Acceptance Payments”):

8.2.3.1 Before 23:59 on December 31, 2009 for the FGD Systems. In the event that Provisional Acceptance of an FGD System is not achieved by a Guaranteed Provisional Acceptance Date that is prior to 23:59 on December 31, 2009, then the following Late Provisional Acceptance Payment shall apply for each day beginning with the day after the Guaranteed Provisional Acceptance Date and ending on the earlier of (i) 23:59 on December 31, 2009, or (ii) the date Provisional Acceptance is achieved:

Dickerson – $25,000 per FGD System per day

Chalk Point – $25,000 per FGD System per day

Morgantown – $25,000 per FGD System per day

8.2.3.2 After 23:59 on December 31, 2009 for FGD Systems. The Late Provisional Acceptance Payments set forth below shall apply in the following circumstances. In the event that the Milestone described as “Ready for Flue Gas to Scrubber” in Exhibit 15 for an FGD System is not achieved before 23:59 on December 31, 2009, then the stated Late Provisional Acceptance Payment shall apply for each day beginning with January 1, 2010, and ending with the day before such Milestone is achieved. In the event that Provisional Acceptance of an FGD System is not achieved by a Guaranteed Provisional Acceptance Date that is after December 31, 2009 then, unless reduced pursuant to Section 8.2.3.4, the stated Late Provisional Acceptance Payment shall apply for each day beginning with the Guaranteed Provisional Acceptance Date and ending with the day before Provisional Acceptance is achieved. The Late Provisional Acceptance Payments applicable to the FGD Systems at each Facility are as follows:

Dickerson – $100,000 per FGD System per day

Chalk Point – $100,000 per FGD System per day

Morgantown – $125,000 per FGD System per day

In the event that there is delay in both achievement of the “Ready for Flue Gas to Scrubber” milestone for a System and achievement of Provisional Acceptance for the same System, then such Late Provisional Acceptance Payments shall apply without duplication. For example, if completion of the “Ready for Flue Gas to Scrubber” milestone for the System is delayed for ten days (i.e., such milestone is not achieved until January 11, 2010), and Provisional Acceptance of the System is delayed by fifteen days (i.e., from a Guaranteed Provisional Acceptance Date of February 28, 2010 until an actual date of Provisional Acceptance of March 16, 2010) then Late Provisional Acceptance Payments will accrue for the ten days of delay in achieving the milestone (from January 1 through 10), but will not accrue for the first ten days of delay in achieving Provisional Acceptance (from February 28 through March 10). Under this example, Late Provisional Acceptance Payments will accrue for the remaining five days of delay in achieving Provisional Acceptance, from March 11 to March 15.

8.2.3.3 Blank.

8.2.3.4 Reduced Late Provisional Acceptance Payments Period. In the event that Provisional Acceptance of an FGD System is not achieved on or before the Guaranteed Provisional Acceptance Date, but such Provisional Acceptance would have been achieved if not for an initial SO2 removal test showing an SO2 removal percentage below 98% but greater than 94%, then the following Late Provisional Acceptance Payments shall apply for each day beginning on the later of (i) January 1,

2010 or (ii) the date of the initial SO2 removal test, and ending on the day before Provisional Acceptance is achieved:

8.2.3.4.1 If the initial test result is less than 98% and greater than 97%, then the Late Provisional Acceptance Payment shall be $30,000 per FGD System per day for the first 30 days, and the full amount set forth in Section 8.2.3.2 for each day thereafter.

8.2.3.4.2 If the initial test result is less than or equal to 97% and greater than 96%, then the Late Provisional Acceptance Payments shall be $30,000 per FGD System per day for the first 26 days, and the full amount set forth in Section 8.2.3.2 for each day thereafter.

8.2.3.4.3 If the initial test result is less than or equal to 96% and greater than 95%, then the Late Provisional Acceptance Payments shall be $30,000 per FGD System per day for the first 19 days, and the full amount set forth in Section 8.2.3.2 for each day thereafter.

8.2.3.4.4 If the initial test result is less than or equal to 95% and greater than 94%, then the Late Provisional Acceptance Payments shall be $30,000 per FGD System per day for the first 10 days, and the full amount set forth in Section 8.2.3.2 for each day thereafter.

8.2.3.5 Amounts Reasonable. The Parties agree that the terms, conditions and amounts fixed as liquidated damages pursuant to Section 8.2.3 for Late Provisional Acceptance Payments are reasonable, considering the actual losses that Owner will incur if Contractor fails to achieve Provisional Acceptance of a System by the Guaranteed Provisional Acceptance Date for such System. The amounts of these liquidated damages are agreed upon and fixed hereunder by the Parties because of the difficulty of ascertaining the exact amount of losses that Owner will actually incur in such event, and the Parties agree that such amounts are a reasonable estimate of Owner’s probable loss (and are not a penalty) and that such amounts will be applicable regardless of the actual losses incurred by Owner. The receipt of any such liquidated damages will not affect, nor be affected by, Owner’s rights to terminate this Agreement pursuant to Sections 23.4 or 23.5.

8.2.3.6 Payment of Late Provisional Acceptance Payments. Owner will invoice Contractor for any Late Provisional Acceptance Payments due under Section 8.2.3 on a monthly basis, and Contractor will be assessed the undisputed portion of each such invoice in full within thirty (30) calendar days of its receipt. If, subject to Section 11.3, an

undisputed amount remains unpaid for more than five (5) days after receipt of notice from Owner that the amount is overdue, Owner may deduct any such amounts due as Late Provisional Acceptance Payments from any unpaid amounts owed by Owner to Contractor under this Agreement.

8.2.4 Guaranteed Substantial Completion Date. Contractor guarantees that Substantial Completion of each of the Systems will occur on or before the “Guaranteed Substantial Completion Date” for each System. The Guaranteed Substantial Completion Date for each FGD System at each Facility shall be the date that is ninety (90) days after date on which such System achieves Provisional Acceptance.

8.2.4.1 Late Substantial Completion Payments. If Substantial Completion of the Work required in connection with a Facility does not occur on or before the Guaranteed Substantial Completion Date for such Facility, then subject only to adjustment of the Substantial Completion Date by Change Order pursuant to Article 19 of this Agreement, Contractor hereby agrees to be assessed to Owner, $500 per calendar day for each calendar day after such Guaranteed Substantial Completion Date until Substantial Completion of all Work required in connection with such System is achieved (“Late Substantial Completion Payments”).

8.2.4.2 Amounts Reasonable and Exclusive Remedy for Delay. The Parties agree that the terms, conditions and amounts fixed as liquidated damages pursuant to Section 8.2.4.1 for Late Substantial Completion Payments are reasonable, considering the actual losses that Owner will incur if Contractor fails to achieve Substantial Completion for a System by the Guaranteed Substantial Completion Date for such System. The amounts of these liquidated damages are agreed upon and fixed hereunder by the Parties because of the difficulty of ascertaining the exact amount of losses that Owner will actually incur in such event, and the Parties agree that such amounts are a reasonable estimate of Owner’s probable loss (and are not a penalty) and that such amounts will be applicable regardless of the actual losses incurred by Owner. The Parties agree that the Late Provisional Acceptance Payments, Excessive Outage Payments, and Late Substantial Completion Payments are the sole and exclusive monetary remedy of Owner for damages it incurs due to delay in completing outages or achieving Provisional Acceptance or Substantial Completion; notwithstanding anything herein to the contrary, Owner reserves all of its rights and remedies under Section 6.10, Article 7, Article 14, Article 23 and Article 28.

8.2.4.3 Payment of Late Substantial Completion Payments. Owner will invoice Contractor for any Late Substantial Completion Payments due under Section 8.2.4 on a weekly basis, and Contractor will

be assessed the undisputed portion of each such invoice in full within thirty (30) calendar days of its receipt. If, subject to Section 11.3, an undisputed amount remains unpaid for more than five (5) days after receipt of notice from Owner that the amount is overdue, Owner may deduct any amounts due as Late Substantial Completion Payments from any unpaid amounts owed by Owner to Contractor.

8.2.5 Guaranteed Final Completion Date. Contractor guarantees that Final Completion of the Work at each Facility will be achieved by no later than ninety (90) days after Substantial Completion of the Work required in connection with the last System at that Facility (such date, the “Guaranteed Final Completion Date” for each Facility).

8.2.6 Late Final Completion Payments. If Final Completion of the Work required in connection with a Facility does not occur on or before the Guaranteed Final Completion Date for such Facility, then subject only to adjustment of the Final Completion Date by Change Order pursuant to Article 19 of this Agreement, Contractor hereby agrees to pay to Owner, $10,000 per calendar day for each calendar day after such Guaranteed Final Completion Date until Final Completion of all Work required in connection with such Facility is achieved (“Late Final Completion Payments”).

8.2.6.1 Amounts Reasonable and Exclusive Remedy for Delay. The Parties agree that the terms, conditions and amounts fixed as liquidated damages pursuant to Section 8.2.6 for Late Final Completion Payments are reasonable, considering the actual losses that Owner will incur if Contractor fails to achieve Final Completion for a System by the Guaranteed Final Completion Date for such System. The amounts of these liquidated damages are agreed upon and fixed hereunder by the Parties because of the difficulty of ascertaining the exact amount of losses that Owner will actually incur in such event, and the Parties agree that such amounts are a reasonable estimate of Owner’s probable loss (and are not a penalty) and that such amounts will be applicable regardless of the actual losses incurred by Owner. The Parties agree that the Late Provisional Acceptance Payments, Excessive Outage Payments, and Late Final Completion Payments are the sole and exclusive monetary remedy of Owner for damages it incurs due to delay in completing outages or achieving Provisional Acceptance or Final Completion; notwithstanding anything herein to the contrary, Owner reserves all of its rights and remedies under Section 6.10, Article 7, Article 14, Article 23 and Article 28.

8.2.6.2 Payment of Late Final Completion Payments. Owner will invoice Contractor for any Late Final Completion Payments due under Section 8.2.6 on a weekly basis, and Contractor will pay be assessed the undisputed portion of each such invoice in full within thirty (30)

calendar days of its receipt. If, subject to Section 11.3, an undisputed amount remains unpaid for more than five (5) days after receipt of notice from Owner that the amount is overdue, Owner may deduct any amounts due as Late Final Completion Payments from any unpaid amounts owed by Owner to Contractor.

8.2.7 Full Program Completion. Once the Contractor has successfully achieved Final Completion of all of its Work at all of the Project Sites, then it will deliver a notice of completion of the Project (the “Notice of Project Completion”) to the Owner for verification. Owner shall, within ten (10) days of receipt of this notice, either approve or validate the notice or provide a specific list of the area or areas in which it believes there are remaining Punch List items to be completed that have not been bought-down by mutual agreement pursuant to Section 17.5. Existence of any Punch List items that have not been bought-down at a Facility shall be grounds for rejection of the “Notice of Project Completion.”

8.2.8 Reduction of Liquidated Damages Based on Delayed Permitting. Should issuance of a permit that is listed in Exhibit 4 as the responsibility of Contractor be delayed beyond the scheduled date indicated in Exhibit 15 for issuance of such permit, Contractor shall promptly prepare for Owner’s review a revised schedule accelerating such work activities as are reasonably necessary to address the impact of such delay so that the immovable milestones may be completed in accordance with Section 8.1.6. After review and discussion of the Contractor’s proposed revised schedule on an Open Book basis, Owner shall enter a Change Order adjusting the Target Cost in accordance with Section 19.14 so as to equitably compensate Contractor for any additional Direct Costs that are Directly Caused by such acceleration. Should Owner fail to issue such a Change Order then, to the extent that such failure is the Direct Cause of a delay in (i) achieving Provisional Acceptance pursuant to Section 8.2.2, (ii) achieving Substantial Completion pursuant to Section 8.2.4 or (ii) achieving Final Completion pursuant to Section 8.2.5:

8.2.8.1 the liquidated damages applicable to the days of delay Directly Caused by the failure of Owner to issue a reasonable Change Order in accordance with Section 19.14 shall be calculated using one-half (50%) of the daily rate that would otherwise be applicable under Sections 8.2.3.1, 8.2.3.2, 8.2.3.4, 8.2.4.1 and 8.2.6; and

8.2.8.2 the total amount of liquidated damages payable by Contractor for delay Directly Caused by failure of Owner to issue a reasonable Change Order pursuant to Section 19.14 shall not exceed the following:

8.2.8.2.1 Five Million Two Hundred and Fifty Thousand Dollars ($5,250,000) for all Systems at Morgantown;

8.2.8.2.2 Three Million Eight Hundred and Fifty Thousand Dollars ($3,850,000) for all Systems at Chalk Point; and

8.2.8.2.3 Two Million One Hundred Thousand Dollars ($2,100,000) for all Systems at Dickerson.

8.3 Schedules. Sections 8.3.1 through 8.3.4 apply to the Approved Project Schedule:

8.3.1 Schedule Software. The schedule has been developed utilizing “Project Planner” project management system software by Primavera. Contractor shall submit subsequent monthly updates, in both hard copy and diskette format at the lowest level of detail.

8.3.2 Activity Coding. The schedule has been developed using a detailed “work breakdown structure” (“WBS”) for activity coding.

8.3.3 Level 3 Detail. The subsequent monthly updates of the Approved Project Schedule shall contain a level of detail consistent with a Level 3 schedule. The subsequent updates of the Approved Project Schedule for each Facility will contain at minimum a specific activity for each group of similar engineering deliverables, material procurement activity, group of similar site deliverables, and work that interfaces with others. The subsequent updates shall also contain specific construction activities for the Work, consistent with the detail afforded by the work breakdown structure.

8.3.4 Schedule Updates. On a monthly basis, Contractor shall submit to Owner on the tenth (10th) day of each calendar month an update of the Approved Project Schedule. This submittal shall be by an electronic transfer method approved by Owner. The updated schedule shall identify any changes in Contractor’s scheduling logic and shall show the status of all activities relative to:

Completion dates

Estimate man-hours

Actual man-hours

Percent complete

Estimated quantities

Actual quantities

8.4 Work Operations. Contractor shall provide Owner, in a timely and convenient fashion, all information regarding Work operations, sequence of Work including work of Subcontractors, breakdown of the Work into individual activities with estimated durations, logical relationships in the schedule for the Work, and descriptions of critical path and non-critical path activities, and monthly schedule updates as required.

8.5 Recovery Schedule. If, in the reasonable opinion of Owner after considering Contractor’s monthly Progress Report and the facts and information known to Owner, Contractor’s Work on critical path activities should fall behind the Approved Project Schedule by greater than one week, the parties will meet to discuss appropriate remedial actions. Based on these discussions, Contractor shall, at Owner’s reasonable request, develop a recovery schedule for review and acceptance by Owner. In order to achieve the recovery schedule, Contractor agrees to take some or all of the following actions: increase manpower, increase Project Work periods, and/or increase concurrency in such quantities and crafts as shall substantially eliminate the backlog of Work. The additional costs of such action shall be treated as Allocable Costs under Section 11.5. This recovery schedule, once approved by Owner, shall be incorporated into the Approved Project Schedule and maintained until the interim schedule milestones in question are accomplished.

8.6 Critical Schedule Situation. If, in the reasonable opinion of Owner after consideration of Contractor’s monthly Progress Report and the facts and information known to it, Contractor’s Work on the critical path activities necessary for Provisional Acceptance of a System fall behind the Approved Project Schedule by greater than one week, and should the Guaranteed Provisional Acceptance Date for such System be less than nine (9) months away (a “Critical Schedule Situation”), then the parties will immediately meet to discuss appropriate remedial actions. Based on these discussions, Contractor shall develop a recovery schedule for review and acceptance by Owner. In order to achieve the recovery schedule, Contractor agrees to take some or all of the following actions: increase manpower, increase Work periods, and/or increase concurrency in such quantities and crafts as shall substantially eliminate the backlog of Work. This recovery schedule, once approved by Owner, shall be incorporated into the Approved Project Schedule and maintained until the delay is eliminated.

8.7 Contractor Responsible for Schedule. Owner’s review and approval of schedules specified within the Contract Documents shall not relieve Contractor of its responsibility for accomplishing the Work according to the Contract Documents. Omissions and errors in the Approved Project Schedule shall not excuse performance less than that required by the Contract Documents. Owner’s approval of Contractor certified and submitted schedules in no way makes Owner an insurer of the success of those schedules or liable for time or cost overruns resulting from shortcomings in such schedules.

9. KEY PERSONNEL REQUIREMENTS

9.1 Personnel Resources.

9.1.1 Key Personnel. The Parties will designate a certain number of Contractor employees as “Key Personnel”. Exhibit 7 identifies individuals designated as Key Personnel as of the Effective Date and a Project organization chart. In addition, any personnel identified on Exhibit 7 shall be considered Key Personnel, regardless of any statement set forth in this Agreement. The Key

Personnel will be highly qualified and capable of fulfilling the responsibilities of their positions, and Contractor will cause each of them to be primarily Dedicated to the Project. The Parties may agree to change the Contractor personnel and/or positions designated as Key Personnel. Contractor shall guarantee that Key Personnel shall be dedicated, devoted and assigned to Work applicable to such personnel’s discipline at each such person’s assigned Facility for as long as and for the duration that their discipline is needed to complete the Work (“Dedicated”).

Contractor acknowledges that the presence of certain Key Personnel at the Facilities is critical to the Project and agrees to make any requested Key Personnel available at the Facilities upon Owner’s reasonable request. Such request will be provided to Contractor at least thirty (30) days before the presence of Key Personnel is required, or, in the case of specialists to be identified by agreement of the Parties, fourteen (14) days; provided that where less than the required notice is provided, Contractor shall use reasonable efforts to make such Key Personnel available.

9.1.2 Departure of Key Personnel. Contractor shall be deemed in default of this Agreement if Contractor breaches Section 9.1.1, except (i) where a Key Personnel leaves his or her employment for reasons that are beyond the reasonable control of Contractor (e.g., retirement, resignation, death, disability, illegal or wrongful activity, etc), (ii) where a change in the person identified as a Key Personnel is agreed to by Owner in accordance with Section 9.1.4, or (iii) where a person identified as a Key Personnel is transferred due to demonstrable personal hardship of the Key Personnel.

9.1.3 Assignment of Key Personnel. Before assigning an individual as a Key Personnel, Contractor will (i) notify Owner of the proposed assignment, (ii) introduce the individual to the Owner’s Authorized Representative (and provide such representative with the opportunity to interview the individual), and (iii) provide Owner with a résumé and other information requested by Owner about the individual. If Owner objects to the proposed assignment for any reason that is not unlawful, Contractor will not assign the individual as a Key Personnel and will promptly propose to Owner another highly qualified individual to serve in such position.

9.1.4 Replacement of Key Personnel. Key Personnel may not be transferred or re-assigned until a suitable replacement has been approved by Owner. Any replacement of Key Personnel, whether requested by Owner or Contractor, must be conducted in accordance with a mutually agreed upon transition plan in accordance with Section 9.2. If any Key Personnel leaves his or her employment with Contractor for reasons that are beyond the reasonable control of Contractor, Contractor may temporarily replace such person, for a period not to exceed sixty (60) days, with a Qualified Person without Owner’s approval until a permanent replacement has been identified to and approved by Owner. For purposes of this Section, a “Qualified Person” shall mean a person of equal or greater education and experience, or as otherwise approved by

Owner. Owner’s approval of replacements for Key Personnel will not be unreasonably withheld or delayed. The Parties agree that promotion will be acceptable grounds for replacing Key Personnel provided that Contractor first identifies a replacement and such replacement is pre-approved by Owner.

9.1.5 Key Personnel of Subcontractors. Owner’s ultimate right to replace an employee of Contractor includes employees of its Subcontractors. Owner shall have the right to instruct Contractor to remove any of its employees or its Subcontractors’ employees from the Project Site or the Work if Owner determines in its reasonable discretion and for reasons that are not unlawful that the continued assignment to the Project of such personnel is not in the best interest of Owner. Owner’s Authorized Representative may request by notice that Contractor remove and replace any such person with another qualified individual. After receipt of such notice, Contractor will remove, or require that its Subcontractor remove such person from the Project and replace such person with personnel possessing qualifications and skills appropriate to the position.

9.1.5.1 For Key Personnel, in a safety or emergency situation, such personnel shall be removed immediately, and replaced as soon as practicable. In all other instances, Key Personnel shall be removed and replaced within 30 calendar days of Owner’s notice.

9.1.5.2 For non-Key Personnel, in a safety or emergency situation, such personnel shall be removed immediately, and replaced as soon as practicable. In all other instances, non-Key Personnel shall be removed and replaced within 30 calendar days of Owner’s notice.

9.2 Contractor Personnel Transition Plan.

9.2.1 Notice of Departure of Key Personnel. Contractor will notify Owner promptly upon determining that any Key Personnel will no longer be serving in such person’s position. Where practicable, notice will be delivered to Owner at least thirty (30) Business Days prior to the date on which such person will cease to serve in such role.

9.2.2 Mutual Agreement. In addition to providing notice to Owner pursuant to Section 9.2.1, Contractor will cause Key Personnel not to be removed or re-assigned from their positions and to continue to perform the Work until the Parties reach mutual agreement regarding a transition plan, unless (i) otherwise requested by Owner or (ii) the continued performance of any such person in such role is impossible due to illness, disability, death or termination of employment. The Parties will promptly begin to negotiate in good faith the terms of the transition plan for the departing personnel immediately following Contractor’s delivery of notice pursuant to Section 9.2.1. Each transition plan will be

developed by the Parties on a case-by-case basis for any departing personnel and will be mutually agreed upon in writing by the Parties. All transition plans will include at least the following: (i) technical requirements (if not already defined), (ii) a timetable for integration of the replacement personnel into the Key Personnel position, and (iii) replacement methodology designed to minimize the loss of knowledge as a result of losing the previous Key Personnel.

9.3 Independent Contractor: Employees. Neither Contractor nor Contractor’s employees are or shall be deemed to be employees of Owner. Contractor shall be solely responsible for the payment of compensation (including provision for employment taxes, federal, state and local income taxes, workers compensation and any similar taxes) associated with the employment of Contractor’s employees. Contractor shall also be solely responsible for obtaining and maintaining all requisite work permits, visas, and any other documentation required under Applicable Law and Applicable Permits for its employees and shall require that all Subcontractors do the same for their employees. Contractor represents that Contractor, its employees, and those Subcontractors authorized by Owner under this Agreement, are authorized to perform services under this Agreement.

9.4 Applicable Time Period. The provisions set forth in this Article 9 shall be applicable and binding upon Contractor from the date of issuance of the LNTP through and up to the date of Final Completion.

10. TARGET COST

10.1 Facility Target Cost. The Target Cost of the Work associated with each Facility is as follows:

Morgantown – $402,621,000.00

Dickerson – $269,329,000.00

Chalk Point – $285,224,000.00

as such Target Cost may be adjusted from time to time pursuant to a Change Order.

10.2 Calculation of Contractor’s Actual Cost.

10.2.1 Categories of Costs. The Actual Cost for Work performed on a System is the sum of the costs for Actual Home Office Labor Costs, Actual Field Non-Manual Labor Costs, Actual Self-Performed Field Manual Services Costs, and Actual Third Party Expenses as described in Sections 10.2.2 through 10.2.5 incurred before the date of the first occurrence of an Initial Performance Test that does not satisfy the applicable Performance Guarantees, plus any such actual costs incurred to perform the Initial Performance Test and to complete the Punch List, but excluding any liquidated damages under Section 8.2.

10.2.2 Actual Home Office Labor Costs. The actual costs for home office labor including labor employed at the Contractor’s home office and at any other location away from a Site (“Actual Home Office Labor Costs”) shall be calculated by multiplying the number of hours spent on tasks necessary for proper performance of the Work by such persons times the labor rates set forth in Exhibit 8D. Such rates are fully burdened including mark-up for SG&A and will not be modified except by Change Order in accordance with Section 19.11 for escalation on January 1 of each year, of five percent (5%) per annum as provided in Exhibit 8D. The reasonable actual cost of travel of persons classified as home office labor shall be allowed only as provided in accordance with Contractor’s travel and expense reimbursement policy in effect on the Effective Date, subject only to non-material annual adjustments such as adjustment of the rate of reimbursement for mileage to match changes in the mileage allowance contained in the Internal Revenue Code.

10.2.3 Actual Field Non-Manual Labor Costs. The actual costs for field non-manual labor including Contractor’s supervisory or management personnel located on a Site (“Actual Field Non-Manual Labor Costs”) shall be calculated by multiplying the number of hours spent on tasks necessary for proper performance of the Work by such persons times the labor rates set forth in Exhibit 8D. Such rates are fully burdened including mark-up for SG&A and will not be modified except by Change Order in accordance with Section 19.11 for escalation on January 1 of each year, of five percent (5%) per annum as provided in Exhibit 8D. The reasonable actual cost of travel of persons classified as field non-manual labor shall be allowed only as provided in accordance with Contractor’s travel and expense reimbursement policy in effect on the Effective Date, subject only to non-material annual adjustments such as adjustment of the rate of reimbursement for mileage to match changes in the mileage allowance contained in the Internal Revenue Code.

10.2.4 Actual Self-Performed Field Manual Services Costs. The actual costs for employees the Contractor has hired to perform construction related tasks at a Site (“Actual Self-Performed Field Manual Services Costs”) shall be calculated by multiplying the number of hours spent on tasks necessary for proper performance of the Work by such persons times the hourly costs for such persons as set forth in certified payrolls and any other evidence as provided by Contractor. The hourly rates stated in Exhibit 8B shall be subject to increase or decrease semi-annually by Change Order pursuant to the process provided in Section 19.10 below. The rates shall be burdened only with the following categories of additional labor-related costs applicable thereto, which shall be adjusted by Change Order pursuant to Section 19.2 in the event of a change in the benefits, safety incentive or per diem paid by Contractor to its employees working on the Project or a change in premiums paid for WC/GL insurance, or by Change Order pursuant to Section 19.9 for a Change in Applicable Law:

Benefits = 5% (initial)

Federal Unemployment Insurance = 0.8% (initial)

State Unemployment Insurance = 2.3% (initial)

FICA/HI = 7.65% (initial)

WC/GL = 5% (initial)

Safety Incentive = $0.5/hour (initial)

Per Diem = $7/hour (initial)

SG&A = 8.5%

The percentage mark-ups for Benefits, FUI, SUI, FICA/HI, and WC/GL shall be applied only to the base published craft labor rate, and shall not be applied to the Safety Incentives or Per Diem. The SG&A shall be applied to the fully-burdened rates including the base craft labor rate, Benefits, FUI, SUI, FICA/HI, WC/GL, Safety Incentive and Per Diem. The percentage mark-ups for FUI, SUI, FICA/HI and WC/GL shall be charged only on the portion of wages and other compensation that is actually subject to tax, withholding or deduction under FUI, SUI, FICA/HI and WC/GL, and shall not apply to any amount of wages or other compensation that exceeds the applicable caps or limitations on wages or other compensation, as provided by relevant statute, regulation or contract.

10.2.5 Actual Third Party Expenses: Unless expressly waived by Owner in writing, all Subcontractors will be selected by Contractor based on a competitive sourcing process demonstrating best value, including subcontractors that are on the approved subcontractor lists included in Exhibit 1, as further supplemented by agreement of the Parties (the “Approved Subcontractor List”). “Actual Third Party Expenses” shall include only payments made by Contractor to Subcontractors or other third parties that are necessary for proper performance of the Work and substantiated by paid invoices. Actual Third Party Expenses shall be marked-up by 8.5% to cover SG&A expenses. Actual Third Party Expenses shall be calculated net of discounts, rebates, insurance proceeds, or other payments or credits of any kind received by Contractor from a Subcontractor or other third party. Subject to the conditions and requirements of this Section 10.2.5, Actual Third Party Expenses may include, among other costs, costs incurred for Commodities, for equipment packages, for furnish & erect subcontracts and for subcontracted labor.

10.2.6 Selling, General and Administrative Expenses. All SG&A costs are included in the rates used for calculating Actual Home Office Labor Costs and Actual Field Non-Manual Labor Costs as set forth in Exhibit 8D, the calculation of Actual Self-Performed Field Manual Services Costs set forth in Section 10.2.4, and the calculation of Actual Third Party Expenses set forth in Section 10.2.5.

These percentage mark-ups will be Contractor’s sole source of recovery or compensation for SG&A costs.

10.2.7 Separate Accounts. Contractor shall keep separate accounts for Actual Costs, Performance Incentives and Guarantee Costs incurred at each Facility for Work performed under the Target Price method (Section 13.2), and shall make such accounts available for Owner’s inspection on an Open Book basis.

10.3 Cap on Contractor’s Total Engineering Hours. Subject to modification by Change Order pursuant to Article 19, Contractor’s total engineering hours to complete the Work, including hours before and after issuance of NTP, shall not exceed the following:

Morgantown = 275,000 hours

Chalk Point = 253,000 hours

Dickerson = 242,000 hours

Any hours in excess of the capped amount shall be the Contractor’s sole expense and shall not be included in the Actual Costs.

11. PRICE

11.1 EPC Total Compensation. “EPC Total Compensation” is the sum of Project Compensation (Section 11.2) plus the Performance Incentives (Section 11.4.2), plus the Underrun Bonus (Section 11.6), plus the Guarantee Costs to be paid by Owner (Section 11.3).

11.2 Project Compensation. “Project Compensation” is calculated in accordance with Article 13.

11.3 Guarantee Costs.

11.3.1 Classification of Guarantee Costs. The “Guarantee Costs” for Work performed on a System is the sum of the costs for Actual Home Office Labor Costs, Actual Field Non-Manual Labor Costs, Actual Self-Performed Field Manual Services Costs, and Actual Third Party Expenses as described in Sections 10.2.2 through 10.2.5 incurred after the date of the first occurrence of an Initial Performance Test that does not satisfy the applicable Performance Guarantees, plus any liquidated damages under Section 8.2, but excluding such actual costs incurred to complete the Punch List. The following sections contain references to costs identified therein as Guarantee Costs:

6.2.3.2 (Permitting Documents)

6.5.4 (Testing)

7.1 (Input Guarantees for FGD Systems)

7.2 (Output Guarantees for FGD Systems)

7.3 (Operational Guarantees for FGD Systems)

11.3.2 Treatment of Guarantee Costs.

11.3.2.1 Blank.

11.3.2.2 Contractor shall keep a separate accounting on an Open Book basis of all Guarantee Costs as they are incurred, and shall include a breakdown and cumulative total of Guarantee Costs in each Progress Report. Guarantee Costs that are identified below as Owner’s payment responsibility shall be included in the calculation of EPC Total Compensation payable by Owner. Guarantee Costs that are identified below as Contractor’s sole responsibility shall not be included in the calculation of EPC Total Compensation payable by Owner. The final responsibility for Guarantee Costs shall be determined as follows:

11.3.2.2.1 If Actual Cost is less than the Target Price, and Guarantee Cost is less than the difference between Target Price and Actual Cost, then Owner shall be responsible for paying Contractor for the Guarantee Costs.

11.3.2.2.2 If Actual Cost is less than the Target Price, and Guarantee Cost is greater than the difference between Target Price and Actual Cost, then Owner shall be responsible for paying the Guarantee Costs up to an amount equal to the difference between Target Price and Actual Cost. Contractor shall be solely responsible, and Owner shall not pay Contractor, for Guarantee Cost in excess of such difference up to the limits of liability as set forth in Article 21. Owner shall be responsible for paying the Guarantee Cost beyond the limits of liability set forth in Article 21.

11.3.2.2.3 If Actual Cost is greater than the Target Price, then Contractor shall be responsible, and Owner shall not pay, for Guarantee Cost up to the limits of liability set forth in Article 21. Owner shall be responsible for paying Guarantee Cost beyond the limits of liability set forth in Article 21.

11.4 Incentives

11.4.1 Blank

11.4.2 Performance Incentives. The following incentives (the “Performance Incentives”) can be earned by Contractor based on its performance:

11.4.2.1 Early Completion of Work During Planned Outages. If an outage is planned exclusively for Contractor, and the Contractor completes its Work during the outage early so that the outage duration is reduced and Owner is able to benefit from this early completion, Owner shall pay Contractor the following incentive:

Morgantown = $35,000 per Unit per day

Chalk Point = $25,000 per Unit per day

Dickerson = $15,000 per Unit per day

11.4.2.1.1 For the purpose of calculation of the above incentive, the outage start shall be 07:00 on the start date and the outage end shall be 23:59 on the end date. Each day of early completion shall be calculated from the end date and time. The following examples illustrate the implementation of this incentive and are for intended solely for clarification purposes:

1. If an outage at Morgantown was to be completed on August 31, 2009, and the outage is complete on August 30, 2009, at 23:00 hours, Owner shall owe Contractor an incentive of $35,000.

2. If an outage at Morgantown was to be completed on August 31, 2009, and the outage is complete on August 30, 2009, at 08:00 hours, Owner shall owe Contractor an incentive of $35,000.

3. If the outage at Morgantown was to be completed on August 31, 2009, and the outage is complete on August 31, 2009, at 02:00 hours, Owner shall owe Contractor an incentive of $0.00.

11.4.2.1.2 The early completion payment for each System shall be paid at Substantial Completion for that System.

11.4.2.2 Safety, Schedule and Quality Incentive.

11.4.2.2.1 During the progress of the Work, the following performance parameters shall be measured:

11.4.2.2.1.1 Safety, on a Per-Facility basis. This incentive includes incentives based on Contractor’s safety record each calendar quarter, and also its safety record for each Facility. The incentive for Contractor’s safety record during a calendar quarter shall be paid if Contractor has met the criteria set forth in the table below. This incentive shall be assessed for safety and spills specified for once each Calendar Quarter in the Approved Final Milestone Payment Schedule. Such incentive shall be payable as part of the first payment after the end of the Calendar Quarter. If there is any incentive that is assessed prior to NTP due to the Contractor, such incentive amount shall be paid with the first safety incentive payment after NTP.

If Contractor does not meet the standard in some of the specified quarters, however meets the standard for the Facility as a whole, the unpaid safety incentive shall be considered earned at Substantial Completion of the last System of the Facility.

Metric	Quarterly Target	Facility Target	Applicable Incentive
Recordables/Record-able Incident Rate	≤ 2 per qtr.	1.55	0.2%
Lost Time Incidents/Lost time Incident Rate	0	0.35	0.25%
Fatality(ies)	0	≤ 1	Keep the Fee
Spills	0	≤ 3	0.05%

11.4.2.2.1.2 Quality, including (i) number of defects in drawings and documents (defects shall be measured in terms of Owner’s written comments or instructions agreed to by the Parties that are not implemented); and (ii) number of defects during supply and installation (defects in materials, non-compliance with drawings and specifications not addressed) that have not been corrected. The report card for the framework that reflects the evaluation of this performance will be mutually agreed to by the Parties.

11.4.2.2.1.3 Schedule, including completion of Milestones with zero delay. This incentive shall be payable if no delay occurs. Incentives not earned in specific Milestones shall not be earned at the end of the Project even though the overall Project was within schedule.

11.4.2.2.2 The following percentages shall be applied to the Milestone Progress Payment as an incentive for Contractor to meet the performance parameters identified in Section 11.4.2.2.1 above:

Safety = 0.5% of each milestone

Quality = 0.25% of each milestone

Schedule = 0.25% of each milestone

11.4.2.2.3 The schedule incentive shall be paid with specific Milestones identified in the Approved Final Milestone Payment Schedule. Accordingly, Contractor shall include a request for this payment as a separate line item in the request for payment of the applicable Milestone Progress Payment. The quality incentives shall be paid at Substantial Completion of the System.

11.5 Allocable Costs.

If payable, the amount of such Underrun Bonus shall equal one-half of the difference between (i) the Target Cost plus Contingency and (ii) the sum of the Actual Cost plus the Guarantee Cost. The amount of the Underrun Bonus shall not exceed $65MM.

12. PAYMENT TERMS

12.1 Payments Generally.

12.1.1 Owner shall pay Contractor the EPC Total Compensation in accordance with this Agreement and shall make all payments if and when due under this Agreement. Wherever Owner’s consent or approval is required, such consent or approval shall not be unreasonably delayed or withheld.

12.1.2 Owner shall make milestone-based payments in accordance with Section 12.2 through 12.3, Guarantee Payments in accordance with Section 12.13 and Final Payment in accordance with Section 12.11.

12.1.3 The Milestone Progress Payment payable at the NTP Milestone shall be equal to: (a) Sixty Million Dollars ($60,000,000) (the “NTP Milestone Payment”), plus (b) ten percent (10%) of the sum of (the Target Cost plus the Target Fee of five percent (5%) applicable to the Target Cost), less (c) the amounts invoiced by Contractor for the Work for the Facility to July 20, 2007. The amounts invoiced but not yet received by Contractor to July 20, 2007 shall be promptly paid by Owner no later than thirty (30) days from receipt of the original invoices by Owner, without the need for further invoicing by Contractor. The NTP Milestone Payment shall be accounted for pursuant to section 12.3.12, and in any reconciliation of the balance of the amount of the Milestone Progress Payment made at NTP, the Target Fee of five percent (5%) of the amounts invoiced by Contractor for the Work to July 20, 2007 shall be excluded from such reconciliation.

12.2 Milestone Progress Payments

12.2.1 A schedule (the “Approved Final Milestone Payment Schedule”) showing the dollar amount associated with each Milestone (the “Incremental Payment Amounts”), and the Calendar Quarter in which the Milestone is scheduled to be completed, is included in Exhibit 9. Exhibit 9 also includes a curve (the “Cash Curve”) based on an original schedule of the cumulative value of Incremental Payment Amounts for Milestones scheduled for completion in each Calendar Quarter. So long as the cumulative total to date of actual Milestone Progress Payments does not exceed the Cash Curve (as is adjusted from time to time by the same Change Order adjustments to the Target Cost and Fee), Contractor is entitled to payment for any completed Milestones irrespective of the number of Milestones or sequence. Notwithstanding, if the Parties mutually agree that, in certain circumstances, it is in the best interest of the Project to allow for increased expenditures, then Owner shall allow for exceeding the Cash Curve or shall otherwise adjust the Cash Curve to a higher level to allow the desired expenditures.

12.2.2 The Approved Final Milestone Payment Schedule shall be used as the basis for preparation of requests for payment, and payment, of progress payments (“Milestone Progress Payments”) to Contractor. Milestone Progress Payments shall be made in accordance with the Milestones achieved under the

Approved Final Milestone Payment Schedule. Upon achievement of a Milestone, Contractor shall submit to Owner for its approval a request for payment for (i) the corresponding Incremental Payment Amount, (ii) the Target Fee associated with this payment that equals Five Percent (5%) of this payment and (iii) any Applicable Safety , Schedule and Quality Incentives as set forth in Article 11.4.2.2 . Each request for payment shall identify in detail the amounts to which Contractor considers it is entitled under this Agreement for the applicable Milestone. As a minimum, each request for payment shall identify the following:

12.2.2.1 the Milestone to which the request for payment relates and the corresponding Incremental Payment Amount for that Milestone;

12.2.2.2 any amount which Owner is entitled to deduct set off or withhold from Contractor;

12.2.2.3 each request for payment shall contain the tax identification number of both Owner and Contractor and all such other information as may be required from time to time under applicable tax laws; and

12.2.2.4 the total amount which Contractor claims under that request for payment.

12.2.3 Contractor can request a partial payment for a Scheduled Milestone where the Work included in that Milestone may not be fully completed, provided Contractor shall submit with its request for payment sufficient documentation satisfactory to Owner to substantiate the cost of the associated Work completed. Each request for partial payment shall identify in detail the amounts to which Contractor considers it is entitled under this Agreement as of the date the applicable Milestone is partially completed. Contractor shall submit to Owner for its approval a request for payment for (i) the corresponding partial payment amount, (ii) the Target Fee associated with this payment that equals Five Percent (5%) of this payment and (iii) any Applicable Safety , Schedule and Quality Incentives as set forth in Article 11.4.2.2. As a minimum, each request for payment shall identify the following:

12.2.3.1 the Milestone to which the request for payment relates and the corresponding Incremental Payment Amount for that Milestone;

12.2.3.2 any amount which Owner is entitled to deduct set off or withhold from Contractor;

12.2.3.3 each request for payment shall contain the tax identification number of both Owner and Contractor and all

such other information as may be required from time to time under applicable tax laws; and

12.2.3.4 the total amount which Contractor claims under that request for payment.

12.2.3.5 the calculations that support the percentage of milestone payment that is being requested.

12.2.4 Any request for payment which is not accompanied by all of the information identified in Section 12.2.2 and 12.2.3 shall not constitute a valid and proper request for payment.

12.2.5 In addition, each request for payment shall include documentary evidence of achieving the corresponding Milestone. Owner shall not be obligated to make payment of amounts in the current month that would cause the cumulative total to date of Milestone Progress Payments to exceed the Cash Curve for the current month, but Owner shall pay such amounts promptly with the next request for payment from Contractor.

12.2.6 Owner shall review each such request for payment and may make such exceptions in accordance with this Agreement within fifteen (15) calendar days of receipt of same. Payment of amounts due and payable shall be made by Owner within fifteen (15) calendar days after the foregoing fifteen-day review period has expired. Unless Owner within the fifteen-day review period confirms that a request for payment does not include all information and documentation required by this Section 12.2, or that the Work included in the relevant Milestone has not been completed properly, then Owner shall make payment to Contractor as provided in this Article 12. If Owner discovers an error in Contractor’s request for payment, Owner shall immediately notify Contractor thereof and upon receipt of a correct request for payment by Contractor shall immediately pay such invoice in accordance with the Agreement.

12.2.7 The payment of any Milestone Progress Payment by Owner shall not constitute approval or acceptance by Owner of the Work, any part thereof or of any item of cost in the corresponding request for payment.

12.3 Quarterly Reconciliation.

12.3.1 Each January, April, July, and October, Owner and Contractor shall work together in good faith to complete, for the immediately preceding Calendar Quarter, the reconciliation activities described in Sections 12.3.2 through 12.3.12.

12.3.2 A “Scheduled Milestone” is a Milestone which, according to the Approved Final Milestone Schedule as modified in accordance with Section 12.1.1.1.4, was scheduled to be completed during the Calendar Quarter being

reconciled or which was re-sequenced by Contractor from prior or subsequent Calendar Quarters to occur in the current Calendar Quarter.

12.3.3 An “Incomplete Milestone” is a Scheduled Milestone that was not completed during the Calendar Quarter being reconciled.

12.3.4 The “Quarterly Reconciliation Ratio” is expressed as a percentage, and is the quotient of (i) the sum of the Incremental Payment Amounts for Scheduled Milestones that were actually completed during the Calendar Quarter, divided by (ii) the total of the Incremental Payment Amounts for all of the Scheduled Milestones for that Calendar Quarter.

12.3.5 The “Quarterly Actual Cost” is the sum of the costs incurred by Contractor for its own personnel or paid by Contractor to third parties during the immediately preceding Calendar Quarter that are verified and documented by Contractor’s records for its own personnel or invoices paid by Contractor to third parties as evidenced by electronic payment receipts or other reliable means of verification and documentation, that are Actual Costs in accordance with Section 10.2. Any costs or expenses about which Contractor and Owner disagree as being Actual Costs shall not be included in the Quarterly Actual Cost for the purpose of the reconciliation and shall be deemed to be “Disputed Costs”. Any Disputed Costs shall be grounds for a Claim by either Party under Article 33. The quarterly reconciliation process shall be conducted solely for the purposes of determining the amount of interim progress payments, and not for the purpose of determining Project Compensation and EPC Total Compensation. Any agreement by Owner and Contractor concerning Quarterly Actual Cost, and any determination or agreement of the Parties regarding Disputed Cost, shall not be relevant or binding for the purpose of determining the Project Compensation and EPC Total Compensation.

12.3.6 The “Reconcilable Cost” is the sum of (i) the Quarterly Actual Cost for a Calendar Quarter multiplied by the Quarterly Reconciliation Ratio for that Calendar Quarter, plus (ii) any Carryover Cost allocated to a delayed Milestone that is completed during that Calendar Quarter.

12.3.7 The “Quarterly Milestone Payment Cost” is the sum of the Milestone Progress Payments made by Owner to Contractor during a Calendar Quarter, less any portion of the Target Fee and Safety, Quality and Schedule Incentive included in those payments.

12.3.8 The “Quarterly Benchmark Cost” is the sum of (i) the Quarterly Milestone Payment Cost, (ii) the Quarterly Contingency Allowance, and (iii) any Approved Contingency Draw Requests approved by Owner for that Calendar Quarter.

12.3.9 To perform the reconciliation, the Reconcilable Cost for the Calendar Quarter shall be compared to the Quarterly Milestone Payment Cost paid by Owner to Contractor for the immediately preceding Calendar Quarter and the Quarterly Benchmark Cost for that Calendar Quarter, as follows:

12.3.9.1 Should the Reconcilable Cost be less than the Quarterly Milestone Payment Cost then the difference shall be deemed an “Excess Payment.” Any Excess Payment shall be deducted from any amount otherwise due and payable by Owner to Contractor under the next payment request submitted by Contractor to Owner. Such amounts shall not be treated as Contingency and shall be available to Contractor in subsequent Calendar Quarters by the use of an internal change order without the need for a Contingency Draw Request. If no further payment requests are to be submitted by Contractor to Owner, then the Excess Payment shall be credited to Owner if due following final reconciliation as set forth in Section 12.11.2 and the calculation of the EPC Total Compensation and Target Final Payment pursuant to Section 12.11.2 and Article 13.

12.3.9.2 Should the Reconcilable Cost be greater than the Quarterly Milestone Payment Cost and less than the Quarterly Benchmark Cost, then the difference between the Quarterly Milestone Payment Cost and the Reconcilable Cost shall be deemed a “Payable Cost”. Contractor shall add the Payable Cost to its next payment request to Owner. If no further payment requests are to be submitted by Contractor to Owner, then Contractor shall submit a separate payment request for the Payable Cost and Owner shall make payment on such application in accordance with the provisions of this Agreement relating to requests for payment.

12.3.10 Should the Reconcilable Cost be greater than the Quarterly Benchmark Cost then:

12.3.10.1 Contractor shall submit a supplemental Contingency Draw Request to support the difference between the Reconcilable Cost and the Quarterly Benchmark Cost, which shall be subject to approval by Owner in accordance with Section 12.6.4; and.

12.3.10.2 the difference between the Quarterly Milestone Payment Cost and the Quarterly Benchmark Cost shall be a Payable Cost and shall be included in a subsequent payment request, and paid by Owner, as provided Section 12.3.9.2; and

12.3.11 A “Carryover Cost” is a cost that is excluded from reconciliation on account of one or more Incomplete Milestones. If there are no Incomplete Milestones during a Calendar Quarter, then the Reconciliation Ratio shall be one (1.0) and there shall be no Carryover Cost from that Calendar Quarter. If there are one or more Incomplete Milestones during a Calendar Quarter, then the Reconciliation Ratio is less than one (1.0) and the Carryover Cost from that Calendar Quarter shall be (i) the Quarterly Actual Cost multiplied by (ii) the difference between one (1.0) and the Quarterly Reconciliation Ratio. If there is one Incomplete Milestone during the Calendar Quarter, the Carryover Cost shall be assigned to that Incomplete Milestone. If there is more than one Incomplete Milestone during the Calendar Quarter, then the Carryover Cost shall allocated and assigned to the Incomplete Milestones in amounts proportional to the Incremental Payment Amounts associated with each such Incomplete Milestone. The Carryover Cost assigned to any Incomplete Milestone shall be added to the Payable Cost for the Calendar Quarter in which that Incomplete Milestone is completed.

12.3.12 The NTP Milestone payment referred to in Section 12.1.3 shall be excluded from the reconciliation described in Sections 12.3.2 through 12.3.11 for the Calendar Quarters beginning with the month the NTP is issued and ending with the month that is twelve (12) months after NTP. Beginning with the thirteenth (13th) month after NTP, the NTP Milestone payment referred to in Section 12.1.3 shall be added back to the Quarterly Actual Cost at the rate of twelve million dollars ($12 million) for each Calendar Quarter until the total of such NTP Milestone Payment amount is accounted for in the reconciliation process.

12.4 Blank

12.5 Payments not made in accordance with Sections 12.2.6, 12.3.12., 12.8, 12.11.2, 12.13 shall be subject to late payment interest at the prime rate reported in the Wall Street Journal on the date such payment is due and payable, plus 1%.

12.6 Contingency

12.6.1 The “Quarterly Contingency Allowance Limit” for each Calendar Quarter is One Million Five Hundred Thousand Dollars ($1,500,000.00). Contractor shall be allowed access and use of the Quarterly Contingency Allowance Limit without prior approval of the Owner. Any unused portion of the Quarterly Contingency Allowance Limit shall not be subject to carryover.

12.6.2 Contractor shall attempt to identify, as early as practicable, any events, causes, conditions, trends or occurrences that are likely to cause the Actual Costs during a Calendar Quarter to be greater than Contractor’s original estimate of the cost of the Work to be performed during that Calendar Quarter by an amount greater than the Quarterly Contingency Allowance. Without limiting Contractor’s rights and other obligations under the Agreement, including its rights

and obligations under Article 19, Contractor shall give notice to Owner, in the form of a written “Contingency Draw Request”, of all such events, causes, conditions or occurrences of which Contractor becomes aware . The Contingency Draw Request shall identify and describe (i) the anticipated or actual magnitude of the cost overrun, (ii) the events, circumstances, conditions or occurrences giving rise to the cost overrun, and (iii) the individual incurred or anticipated cost items involved.

12.6.3 When complete information is not readily available, Contractor shall issue a “Contingency Draw Notification” including such information as is reasonably available at the time. Contractor may convert a Contingency Draw Notification to a Contingency Draw Request by providing the information specified in Section 12.6.2. While such notification cannot form part of the quarterly reconciliation process, the notification will provide a basis for more expeditious consideration by Owner of a cost, when it is converted to a Contingency Draw Request.

12.6.4 Upon receipt by Owner of a Contingency Draw Request, Owner and Contractor will discuss any measures that Contractor has taken, and any additional steps that Contractor or Owner might take, to minimize or eliminate the potential cost overrun and any time limits or other practical limitations relating to such additional steps. Owner and Contractor shall make a good-faith effort to work collaboratively to determine what work-around steps or alternate measures may be appropriate. Owner may by written notice to Contractor, based on these discussions and collaborative efforts, approve a Contingency Draw Request in whole or in part. Any dispute with respect to Owner’s approval of Contingency Draw Request shall be subject to provisions of Article 33.5.

12.7 The quarterly reconciliation process shall be conducted solely for the purposes of assisting in the determination of the amount of interim progress payments, and not for the purpose of determining Project Compensation and EPC Total Compensation. Any use of the Quarterly Contingency Allowance, approval of a Contingency Draw Request, or determination or agreement of the Parties regarding Disputed Cost, shall not be relevant or binding for the purpose of the determining the amount of Project Compensation and EPC Total Compensation.

12.8 Retention. Owner shall retain from each payment made for each Milestone Progress Payment pursuant to Section 12.2.1, Payable Cost pursuant to Section 12.3.9.2, and Carryover Cost pursuant to 12.3.11 (when paid), ten percent (10%) of the amount due and payable to Contractor; provided, however, that no such retention shall be withheld from the amount of the Milestone Progress Payment made at the time of issuance of the NTP pursuant to section 12.1.3 nor from the payment of invoices outstanding to July 20, 2007. Upon Substantial Completion of each System, Owner shall remit to Contractor fifty percent (50%) of the amount retained with respect to such System. Owner shall remit the balance of the retention in the Final Payment.

12.9 A Change Order that increases or decreases the Cost Element and/or the Fee Element shall also increase or decrease the amount of each Milestone Progress Payment in the Approved Final Milestone Payment Schedule. The amount of the increase or decrease to each Milestone Progress Payment shall be calculated by multiplying the increase or decrease in the Contract Price stated in the Change Order times the Incremental Percentage for each such Milestone. In addition, the amount of a Milestone Progress Payment may be changed pursuant to Section 12.2.1 or by mutual agreement of the Parties in writing. Other than as provided in this Section 12.9, the Milestone Progress Payments contained in the Approved Final Milestone Payment Schedule shall not be increased or decreased.

12.10 Conditions of Payments; Withholdings, Set-Offs.

12.10.1 Material Breach. Notwithstanding Sections 12.1, 12.11, and 12.13, Owner may withhold payment to Contractor pursuant to Section 12.10.3 if Contractor is in material breach of its obligations under this Agreement.

12.10.2 Required Submittals. Notwithstanding Section 12.1.2, Owner will not be required to make any payment to Contractor until Contractor has provided the submittals described in Sections 12.2.2 and 12.2.3 and any other lien-waiver documentation as Owner may reasonably request and which is not inconsistent with standard practice in similar construction projects in the State of Maryland.

12.10.2.1 Progress Reports. In order for each request for payment to be valid, Contractor must have submitted to Owner all monthly Progress Reports required under Section 8.2.1.1. if due prior to the date of such request for payment.

12.10.2.2 Partial Lien Waivers. In order to be valid, each request for payment submitted by Contractor must be accompanied by partial lien waivers and releases in the form attached as Exhibit 16 executed by Contractor and all Subcontractors with whom Contractor has a direct contract or purchase order, and who submitted an invoice or application for payment to Contractor more than thirty (30) days prior to Contractor’s application for payment to Owner. In addition, and at Owner’s request, Contractor shall submit such lien waivers of any and all other Subcontractors who may have the right to pursue a mechanic’s or materialman’s lien under Applicable Law.

12.10.2.3 Full Lien Release In order to be valid, Contractor’s invoice for the final payment from Owner under this Agreement must be accompanied by full lien releases and waivers executed by Contractor and all Subcontractors which have provided equipment or materials or performed work at the Site in the prior 180 days.

12.10.2.4 Form of Waivers and Releases. The lien waivers and releases required from Contractor under this Section 12.10.2 must be in the form and substance as set forth in Exhibit 16.

12.10.2.5 Lien Bonds. Notwithstanding the other provisions of Section 12.10, Contractor may substitute lien discharge bonds sufficient under applicable law to remove any lien attaching to a Site, or other security reasonably acceptable to Owner in lieu of the lien waivers required hereunder.

12.10.3 Withholding to Protect Owner from Loss. Notwithstanding Sections 12.1 through 12.9, Owner may, without prejudice to any other rights Owner may have under this Agreement, withhold all or any portion of any payment to such extent as may be reasonably necessary to protect Owner from loss due to: (i) defective or incomplete Work by Contractor or any of its Subcontractors; (ii) claims filed by third parties arising out of Contractor’s performance of the Work for which Contractor has an indemnity obligation or other responsibility under the Agreement; (iii) failure of Contractor to make payments to Subcontractors (other than as a result of non-payment by Owner to Contractor); (iv) reasonable evidence that a System will not be completed by the Guaranteed Substantial Completion Date for such System and that the retention, Letter of Credit and unpaid balance would not be adequate to cover liquidated damages for the anticipated cumulative delay on all Systems; (v) damage to Owner caused by Contractor or its Subcontractors (provided, that if such damage is only partially caused by Contractor or its Subcontractors, Owner may only withhold a portion of such damage equal to the relative degree of fault of Contractor or its Subcontractors in causing such damage) for which Contractor has an indemnity obligation or other liability under this Agreement; (vi) liens filed against a System, Facility, Site or any other property of Owner by Subcontractors which Contractor fails to remove, discharge or bond over; or (vii) failure by Contractor to maintain the insurance required by this Agreement. Notwithstanding the foregoing, Contractor may substitute bonds or other reasonable security for specific items in question under Sections 12.10.3.2 or 12.10.3.3, subject to the agreement of Owner which will not be unreasonably withheld or delayed.

12.10.3.1 In addition, upon prior notice to Contractor, Owner may withhold or retain any Milestone Progress Payment, payment or part thereof in any of the following circumstances:

12.10.3.1.1 A Contractor Event of Default shall have occurred;

12.10.3.1.2 Any lien or charge has been created on the Facility, the Work or any portion thereof by Contractor or a Subcontractor based on Work for which Owner has made payment to the Contractor

pursuant to this Agreement, and such lien or charge has not been discharged; or

12.10.3.1.3 Owner has performed any part of the Work in lieu of Contractor.

12.10.3.2 Lien Bonds. Notwithstanding Section 12.10.3(vi) and 12.10.3.1.2, Owner will release any payments withheld due to any lien if Contractor obtains a lien discharge bond which is (i) issued by a surety reasonably acceptable by Owner, (ii) in form and substance satisfactory to Owner, and (iii) in an amount sufficient under applicable law to remove the lien from Owner’s property. By posting a lien discharge bond, however, Contractor will not be relieved of any obligations (including its indemnity obligations) under this Agreement. The premium for any such lien discharge bond shall be treated as an Allocable Cost pursuant to Section 11.5.

12.10.3.3 Payment after Removal of Cause. When Contractor has remedied the cause for withholding any payment and has furnished satisfactory evidence of such remediation to Owner, Owner will make the payment so withheld to Contractor within ten (10) calendar days following Owner’s receipt of such evidence. If Contractor, after receipt of notice from Owner, fails or refuses to remedy the cause for withholding such payment within the time specified in the notice, then Owner may, without prejudice to any other rights Owner may have under this Agreement, remedy it, but such action by Owner will not be or be considered to be a waiver of any default by Contractor under this Agreement.

12.10.4 Set Off. Owner may set off any sums payable by Contractor to Owner under this Agreement against any payments due to Contractor under this Agreement.

12.11 Final Payment for Target Work at Each Facility.

12.11.1 For Work performed at each Facility, Contractor shall check all materials, equipment and labor involved with or incorporated into the Work and shall keep on an Open Book basis (and require all Subcontractors performing work on a cost-plus basis to keep) full, detailed and accurate records and accounts thereof, showing the Actual Costs of all items of labor, materials, supplies, services and other expenditures of whatever nature for which payment or reimbursement is authorized or required under this Agreement, and the system of accounting shall be satisfactory to Owner. Contractor shall retain and preserve all such records for not less than three (3) years after Target Final Payment.

12.11.2. At the time that Contractor submits a Notice of Final Completion for Work performed under the Target pricing method (Section 13.2), Contractor shall submit to Owner on an Open Book basis a final accounting of all Actual Costs and Guarantee Costs incurred in performing such Work, in accordance with Section 10.2 and Section 11.3. Owner’s accountants will review Contractor’s accounting and may request such further information as is necessary for Owner to substantiate the accounting and to determine the amount of Actual Costs and Guarantee Costs incurred. Based on its review of Contractor’s accounting, Owner shall determine and pay, within thirty (30) days after the date of Final Completion of a Facility, the unpaid amount (excluding Guarantee Costs to be paid at a later date pursuant to Sections 12.13) of EPC Total Compensation for such Work (the “Target Final Payment”) and shall release all remaining retention amounts, less any amounts that may be due and payable by Contractor to Owner. Should Owner’s review of Contractor’s accounting show that a net amount is owed by Contractor to Owner, Contractor shall pay such amount to Owner within thirty (30) days of demand for such payment by Owner.

12.11.3 When application for Target Final Payment is submitted by the Contractor, the Contractor shall assure that the following documents or conditions have been previously completed, submitted and approved by Owner:

12.11.3.9 Mill certifications.

12.12 Liens After Final Payment. Should there be any claim, obligation, or lien existing for Work for which Target Final Payment has been made, then Contractor shall refund to Owner all monies that Owner shall have paid or may be obligated to pay in satisfying, discharging, or defending against any such claim, obligation or lien or any action brought or adjustment recovered thereon, including all costs and expenses, including attorney’s fees and disbursements incurred in connection therewith.

12.13 Payment of Guarantee Costs. Guarantee Costs incurred by Contractor in connection with the FGD Systems and for which Owner is responsible for payment pursuant to Section 11.3.2 shall be paid to Contractor as follows:

12.13.1. Separate Accounting. Contractor shall keep a separate accounting of all Guarantee Costs incurred to satisfy Contractor’s obligations to correct the Work, to repair or replace affected parts or systems and to retest, due to failure to satisfy the Equivalent Availability Guarantee as set forth in Sections 7.2.1.3 and 7.2.2. To the extent that Owner is responsible pursuant to Section 11.3.2.2 for paying such Guarantee Costs, payment of same shall be made within thirty (30) days after the Equivalent Availability Guarantee is satisfied.

12.13.2. Prior to Target Final Payment. Guarantee Costs for which Owner is responsible for payment pursuant to Section 11.3.2.2, that are incurred prior to Target Final Payment and are not addressed under Section 12.13.1 shall be paid to Contractor in the Target Final Payment.

12.13.3. After Target Final Payment. In the event that Contractor incurs Guarantee Costs subsequent to Target Final Payment that are not addressed under Section 12.13.1, and all of Contractor’s responsibility for Guarantee Costs has been exhausted, then Contractor may submit monthly requests for payment to Owner for such Guarantee Costs, and Owner will make payment on such requests for payment in accordance with the accounting procedure set forth in Sections 12.11.1 and 12.11.2.

19. CHANGE ORDERS

19.1 Changes. Without invalidating this Agreement, Owner may issue an order making Changes (each such order, a “Change Order”) to the Work, in which event one or more of the Contract Price or the Approved Project Schedule may be adjusted as provided in this Article 19. Changes may only be authorized by Change Orders issued in accordance with this Article 19. Change Orders will constitute the exclusive remedy to Contractor for any Changes.

19.2 Procedure for Changes.

19.2.1 Changes Initiated by Contractor. Should Contractor become aware of any circumstances which Contractor has reason to believe may necessitate a Change, Contractor will issue to Owner a written “Change Order Notice.” All Change Order Notices will include, to the extent practicable, documentation

sufficient to enable Owner to determine (i) the factors necessitating the possibility of a Change, (ii) the impact which the Change is likely to have on the Contract Price based on the time and materials rate charges in effect at the time of the Change pursuant to Section 10.2 of this Agreement, (iii) the impact which the Change is likely to have on Contractor’s compliance with the Approved Project Schedule, and (iv) such other information which Owner may request in connection with such Change. If Contractor fails to provide a Change Order Notice to Owner within fifteen (15) Business Days after Contractor knew about the first occurrence or circumstance resulting in the possibility of such Change, then notwithstanding anything in this Article 19 to the contrary, Contractor agrees that Owner’s ability to exercise its rights pursuant to Section 19.16 shall have been compromised and Contractor will be deemed to have waived any right to receive a Change Order based upon such occurrence or circumstance. Owner may, but except as provided in Sections 19.3, 19.4, 19.5, 19.6, 19.7, 19.9, 19.10, 19.11 and 19.12below, will not be obligated to, issue a Change Order pursuant to a Change Order Notice.

Contractor shall supplement this analysis on an Open Book basis with such other information as Owner may reasonably require. Any Change Order extending any date in the Approved Project Schedule will only extend such date(s) by a number of calendar days, at a maximum, equal to the number of calendar days of delay Directly Caused to the actual critical path of the Work at the time of the event giving rise to the Change Order and only to the extent that such delay to the critical path progress of the Work has been demonstrated by Contractor to Owner’s reasonable satisfaction.

19.14 Changes to the Contract Price. Within five (5) Business Days of submission of a Change Order Notice under Section 19.2.1, or within ten (10) Business Days after submission of a Change Order Request under Section 19.2.2, the Contractor shall prepare and submit, on an Open Book basis, an analysis of the impact of the Change on the Cost Element for the System, Facility, or Project, as the context may require.

Contractor shall supplement this analysis on an Open Book basis with such other information as Owner may reasonably require. The amount of an increase or decrease in the Cost Element and Fee Element, if any, resulting from a Change will be determined and will be included in the Change Order as follows:

19.14.1 in a lump sum amount proposed by Contractor and accepted by Owner; or

19.14.2 if Owner does not accept the lump sum amount proposed by Contractor, by unit prices agreed upon by the Parties; or

19.14.3 if neither of the methods set forth in Sections 19.14.1 or 19.14.2 is agreed upon after good faith negotiation by the Parties, Contractor will provide Owner with such purchase orders, invoices, Subcontractor quotes and other documents and records as Owner may require to verify, to its satisfaction, Contractor’s incremental Direct Costs or savings of effecting such Change (or Directly Caused by the event necessitating such Change) (“Contractor’s Additional Direct Costs or Savings”). All equipment, materials, labor, equipment rental and other items associated with such Change will be purchased by Contractor at competitive market prices. Owner will, upon verifying Contractor’s Additional Direct Costs or Savings associated with such Change, adjust the Cost Element by an amount equal to such Contractor’s Additional Direct Costs or Savings, the calculation of these shall be in accordance with the methodology used to develop the Target Cost. Owner will make appropriate adjustments to the amount of the applicable Incremental Payment Amount in the Approved Final Milestone Payment Schedule.

19.14.4 A Change Order that increases or decreases the Cost Element shall also increase or decrease the Fee Element in an amount calculated by multiplying the percentage Fee times the amount of the increase or decrease in the Cost Element. The amount of increase or decrease in the Cost Element and the Fee Element shall be stated separately on each Change Order. Adjustment in the Fee Element as provided in this Section 19.14.4 shall be Contractor’s sole remedy and sole means for adjusting its margins for profit, overhead, or similar costs due to Changes in the Work, and Contractor expressly waives any claims for modification of such margins based on cardinal change or other legal or equitable theories.

19.15 Continued Performance Pending Resolution of Disputes. Notwithstanding and pending resolution of any dispute with respect to a Change, Contractor must proceed, upon written notice from Owner, with the performance of any Change ordered by Owner. Contractor will be reimbursed provisionally on a time and material basis for any such Change ordered by Owner that increases the scope of the Work. For disputed Changes that do not increase the scope of the Work, Contractor may request provisional reimbursement. Should Owner deny such provisional reimbursement, Contractor may submit a request for provisional reimbursement to the DRB pursuant to Section 33.5.

19.16 Owner’s Right to Offset Changes. Whenever it is determined that any Changes may require an extension of the Approved Project Schedule, Owner may, at its sole discretion and to the extent possible, elect to offset all or any part of such extension with other Changes (including but not limited to Changes to the Contract Price) that will maintain the Approved Project Schedule. Whenever it is determined that any Changes may require an increase in the Contract Price, Owner may at its sole discretion and to the extent possible, elect to offset all or any part of such increase with other Changes (including but not limited to Changes to the Approved Project Schedule) that will maintain the Contract Price.

19.17 Other Work on Site. Owner reserves the right to perform, and to award separate contracts for the performance of, construction or operations related or ancillary to other work on the Site. Contractor will in good faith coordinate its performance of the Work with any activities of Owner and/or other contractors operating at the Site or at the Facility.

20. FORCE MAJEURE

20.1 Force Majeure. At each particular Site, an event of “Force Majeure” will mean any act or event that prevents or delays the affected Party from performing its obligations under this Agreement or complying with any conditions required by the other Party under this Agreement if such act or event is beyond the reasonable control and not the fault of the affected Party and such Party has been unable by the exercise of all reasonable efforts to prevent, overcome or mitigate the effects of such act or event.

20.3.3 the Party claiming Force Majeure uses its best efforts to overcome or mitigate the effects of such occurrence;

20.3.4 when the non-performing Party is able to resume performance of its obligations hereunder, that Party will give the other Party written notice to that effect and will promptly resume such performance; and

20.3.5 No Force Majeure event shall excuse Owner’s payment obligations.

20.4 Costs. Any additional Direct Cost incurred by Contractor in performing Work, and Directly Caused by Force Majeure shall not be grounds for an increase in the Target Cost by Change Order pursuant to Section 19.3 until the aggregate of such Direct Costs shall equal or exceed two million dollars ($2,000,000), and Contractor shall only be entitled to a Change Order based on Force Majeure for the additional Direct Costs incurred by Contractor that exceed two million dollars ($2,000,000).

22. SECURITY

22.1 Contractor’s Parent Company Guarantee. No later than ten (10) Business Days after issuance of the NTP, Contractor shall provide a parent company guarantee acceptable to the Owner which shall guarantee all of Contractor’s obligations under this Agreement; provided, however, that the obligations of the guarantor under such guarantee shall be limited to three hundred million dollars ($300,000,000).

22.2 Contractor’s Letter of Credit. Contractor shall provide a letter of credit in form and substance acceptable to Owner (as shown in Exhibit 11) from a mutually acceptable U.S. financial institution (“Letter of Credit”) in the following amounts and at the following times:

22.2.1 Not later than ten (10) Business Days after issuance of the LNTP, Contractor has provided a Letter of Credit in an amount equal to the purchase order issued by Owner to Contractor for the Work to be performed under the LNTP, excluding the value of the purchase order allocated to Systems Equipment to be purchased from Subcontractors. Contractor shall use good faith efforts to obtain from such Subcontractors, to the extent commercially practicable, letters of credit securing the performance of the Subcontractors. Such letters of credit shall be in the greatest amount practicable and shall be in favor of and drawable by Owner until such time as Contractor satisfies its obligation to provide the $50,000,000 letter of credit required by Section 22.2.3.

22.2.2 Not later than ten (10) Business Days after issuance of the INTP, Contractor shall amend the Letter of Credit or provide a new substitute Letter of Credit equal to the amount of the purchase orders issued by Owner to Contractor for the Work performed or to be performed under the LNTP and INTP, excluding the value of the purchase order allocated to Systems Equipment to be purchased from Subcontractors. Contractor shall use good faith efforts to obtain from such Subcontractors, to the extent commercially practicable, letters of credit securing the performance of the Subcontractors. Such letters of credit shall be in the greatest amount practicable and shall be in favor of and drawable by Owner until such time as Contractor satisfies its obligation to provide the $50,000,000 letter of credit required by Section 22.2.3.

22.2.3 Not later than ten (10) Business Days of issuance of the NTP for FGD Systems, Contractor shall amend the Letter of Credit or provide a new substitute Letter of Credit equal to fifty million dollars ($50,000,000). The Letter of Credit in this Section 22.2 shall remain in effect and drawable by Owner until Substantial Completion of all Work for the last System on each Facility whereupon, the amount of the Letter of Credit will be stepped down by an amount proportionate to the relative Target Cost of such Facility to the sum of the Target Costs for all three Facilities. The Letter of Credit shall be promptly returned to Contractor upon the last System of the last Facility achieving Substantial Completion. To the extent that any replacement of a Letter of Credit is required to maintain compliance with this Section 22.2, Contractor shall deliver the replacement Letter of Credit to Owner no later than thirty (30) days prior to the date when the existing Letter of Credit will expire. In the event of a failure to comply with the preceding sentence, Owner shall be entitled to draw upon the existing Letter of Credit prior to the expiration thereof and take such further action to protect its interests pursuant to this Agreement.

22.3 Performance Bond and Payment Bond. To further assure Contractor’s performance under this Agreement, within ten (10) Business Days after the issuance of the NTP for FGD Systems, Contractor will furnish to Owner a performance bond and a payment bond each having a face value of one hundred and fifty-five million dollars ($155,000,000). The combined penal sum of both bonds in the aggregate shall not exceed the face value of either bond. Such performance and payment bonds shall be substantially in the form set forth in Exhibit 12. The payment bond shall remain in effect and drawable until Final Completion. The performance bond will remain in effect and drawable until Substantial Completion. The face value of the performance bond shall be stepped down as each Facility achieves Substantial Completion and the face value of the payment bond shall be stepped down as each facility achieves Final Completion (the step-down being in an amount proportionate to the relative target Cost of the Facility to the sum of the Target Costs of all three Facilities). The payment bond shall be promptly returned to Contractor upon the last Facility achieving Final Completion. At Substantial Completion of the last Facility, the performance bond provided at NTP shall be replaced with a performance bond covering all obligations of Contractor under Article 14 and Sections 7.2.2 for the Equivalent Availability Guarantee referred to in Section 7.2.1.3 with a penal sum equal to ten percent (10%) of the Contract Price of the Project (the “Warranty Bond”). In no event shall the combined penal sum of the performance bond provided at NTP, and the Warranty Bond be less than ten percent (10%) of the Contract Price for the Project.

22.4 Owner Security. No later than ten (10) Business Days of issuance of the NTP for FGD Systems\, Owner shall provide a letter of credit in form and substance acceptable to Contractor (as shown in Exhibit 11) from a mutually acceptable U.S. financial institution (“Letter of Credit”) for an amount of $55,000,000 (the “Owner Security”). Contractor can request a change in Owner’s Security to an amount not to exceed $80,000,000 in the event that Contractor’s committed cost exposure increases.

Contractor shall include in such request all documents as requested by Owner to justify the increase. If Owner is satisfied, Owner will amend the Letter of Credit to the approved value. Such amendment shall be issued no later than Ten (10) business days from such approval. The letter of credit in this Section 22.4 shall remain in effect and drawable by Contractor until release of fifty percent (50%) of the retention at Substantial Completion of each System, whereupon, the amount of the letter of credit will be stepped down by an amount proportionate to the relative Target Cost of the Facility to the sum of the Target Costs of all three Facilities. The letter of credit shall be promptly returned to Owner upon Substantial Completion of the last System at the last Facility and release of the corresponding fifty percent of retention for that System. To the extent that any replacement of a Letter of Credit is required to maintain compliance with this Section 22.4, Owner shall deliver the replacement Letter of Credit to Contractor no later than thirty (30) days prior to the date when the existing Letter of Credit will expire. In the event of a failure to comply with the preceding sentence, Contractor shall be entitled to draw upon the existing Letter of Credit prior to the expiration thereof and take such further action to protect its interests pursuant to this Agreement. Upon the issuance of the INTP, Owner shall provide to Contractor a parent company guarantee in a form acceptable to Contractor and issued by Mirant North America, Inc., which shall guarantee the payment obligations of the Owner under this Agreement and the EPC Agreement up to the maximum amount of sixty-two million five hundred thousand dollars ($62,500,000).

23. SUSPENSION AND TERMINATION

23.1 Right to Stop Work for Cause. If, due to Contractor’s failure (i) to correct defective Work under Section 6.10.2, (ii) to meet its repair or replacement obligations under Section 28.1; (iii) to meet its safety obligations under Section 6.8; (iv) to meet its obligations to complete Punch-List items as provided in Section 17.5; (v) to achieve Provisional Acceptance on or before the date that is thirty (30) days after the applicable Guaranteed Provisional Acceptance Date, or (vi) to perform the Work in accordance with the Approved Project Schedule such that Owner can reasonably deduce that Contractor will not complete the Work necessary to comply with the requirements for an outage in accordance with Section 8.2.1.2, Owner shall be entitled to take any of the Owner-cure actions under such Sections, then Owner may, by a written order signed by its Authorized Representative, order Contractor to stop performing all or a portion of the Work in order to allow Owner to take such actions. The foregoing right of Owner to stop Contractor’s performance will not give rise to any duty on the part of Owner to exercise this right for the benefit of Contractor or any other person or entity. In addition, Owner, by written order signed by its Authorized Representative, may order Contractor to stop performance if the activities of Contractor or Contractor’s Subcontractors reasonably appear to Owner to cause or threaten to cause damage to the property of Owner. In the event of such a stop order, Contractor will not be entitled to a Change Order extending the Approved Project Schedule. The cost of any delays experienced by Contractor as a result of orders issued by Owner ordering Contractor to stop performance hereunder will be borne by Contractor. Owner’s right to stop work under this Section 23.1 will be without prejudice to any other right or remedy Owner may have under this Agreement.

23.2 Right to Suspend Work for Convenience. Owner may at any time and from time to time, by a written order signed by its Authorized Representative, suspend (and later reinstate) all or a portion of the Work without terminating this Agreement. Upon receipt of such order, Contractor will immediately suspend its performance of the Work. In the event of a suspension of the Work, Contractor shall use its best efforts to mitigate potential delays to the date of Substantial Completion and to minimize the amount of personnel and equipment that is idled and the costs associated with such suspension. If Owner suspends the Work pursuant to this Section, then Contractor will be entitled to a Change Order as described in Section 19.4.

23.3 Suspension by Contractor. Subject to Sections 19.15 and 33.6 for amounts that are disputed in good faith, if Owner fails to pay to Contractor any payment when due under this Agreement and such failure continues for fifteen (15) calendar days after written notice thereof has been received by Owner from Contractor, and so long as such notice from Contractor to Owner was given at least five (5) days after payment was due, then Contractor may suspend the Work until payment of the amount owing has been received.

23.4 Termination by Owner for Convenience.

23.4.1 Right to Terminate. Owner may, at any time and for any reason, terminate all or any part of this Agreement (provided that termination of part of the Agreement shall not be for substantially the entire scope for a Facility, unless Owner decides not to proceed with the Work for the Facility) for Owner’s convenience and without cause by providing Contractor with written notice regarding the same. In the event of partial termination, the remaining Work under this Agreement shall be performed in accordance with all of the terms and conditions of this Agreement, and the Target Cost and Fees will be increased or decreased in proportion to the value of the Work terminated.

23.4.2 Termination Payment. Within thirty (30) calendar days of Contractor’s having received notice from Owner under Section 23.4.1, Owner will reimburse Contractor for completed Work and work-in-progress, applicable vendor cancellation charges, demobilization costs, and reasonable costs to bring the work to an orderly conclusion (collectively the “Termination Payment”). The Termination Payment will be Contractor’s sole and exclusive remedy for such termination. Owner will not be liable to Contractor, any Subcontractor or any other party for any damages or indirect, special, incidental costs or consequential liability resulting from such termination, including without limitation, prospective profits on Work not performed or other consequential or incidental damages. The Parties recognize, agree and acknowledge that Owner’s termination right hereunder is a permitted action under this Agreement (and not a breach hereof or a default hereunder), which right carries with it the obligation to make the Termination Payment. In the event of termination by Owner for convenience, Contractor’s liability limitations that are expressed as a percentage

of the Contract Price shall instead be calculated as a percentage of the actual compensation paid to Contractor.

23.4.3 Withholding/Conditions Precedent. Notwithstanding Section 23.4.2 Owner may withhold from such Termination Payment any unpaid amounts due from Contractor to Owner under this Agreement. Furthermore, the following will be conditions precedent to Owner’s obligation to pay Contractor the Termination Payment: (i) Contractor’s executing and delivering all such documents and taking all such steps, including the assignment of Contractor’s contractual rights, as Owner may require for the purpose of fully vesting in Owner all rights, title and interests of Contractor in and to all subcontracts, purchase orders, warranties, guarantees and other agreements pertaining to the Work; (ii) Contractor’s executing and delivering to Owner all waivers and releases, in form and substance acceptable to Owner, required to establish that the Systems, the Facility and the Site, and any and all interests, estates or improvements related thereto, are free from any and all claims, liens, security interests or encumbrances arising out of or in connection with performance by Contractor or any Subcontractor of the Work; (iii) Contractor’s delivering to Owner any other information reasonably requested by Owner; and (iv) Contractor’s delivery to Owner of assignments of any agreements with Subcontractors for which Owner requests assignment.

23.4.4 Return of Security In the event of termination for convenience pursuant to this Section 23.4, and subject to all of the rights of the Parties under the Contract Documents, (i) Owner shall return the original Letter of Credit issued by Contractor pursuant to Section 22.2 to Contractor for cancellation; (ii) Contractor shall return the original Letter of Credit issued by Owner pursuant to Section 22.4 to Owner for cancellation; (iii) Owner shall return the original Payment and Performance Bond issued by Contractor pursuant to Section 22.3 to Contractor for cancellation; and (iv) Owner shall pay all undisputed retainage to Contractor. Upon request of either Party, the exchange of Letters of Credit and Payment and Performance Bonds pursuant to subparts (i), (ii) and (iii) shall be simultaneous.

23.5 Termination by Owner for Cause. If a Contractor Event of Default occurs, then Owner may, without prejudice to any other right or remedy Owner may have under this Agreement and notwithstanding any other provision under this Agreement, at any time terminate all or any part of this Agreement, such termination becoming effective seven (7) calendar days after notice thereof is provided from Owner to Contractor. For purposes hereof, a “Contractor Event of Default” will be deemed to have occurred if:

23.5.1 Insolvency. Contractor is adjudged as bankrupt or insolvent, makes a general assignment for the benefit of its creditors, has a trustee or receiver appointed for its property, or files a petition to take advantage of any debtor’s act;

23.5.2 Delay After Provisional Acceptance. (a) Provisional Acceptance of an FGD System has failed to occur on or before the date that is thirty (30) calendar days after the Guaranteed Provisional Acceptance Date for such System as adjusted by Change Order, and (b) Contractor has not provided an acceptable recovery plan to Owner;

23.5.3 Key Personnel. Breach by Contractor of Article 9 of this Agreement (“Key Personnel”); or

23.5.4 Material Breach. Contractor otherwise refuses to perform, or commits a material breach, of any of the terms of this Agreement and fails to cure such breach within a reasonable time after notice.

Upon such termination or partial termination Owner may take possession of the applicable portion of the Site and of the applicable materials, equipment (including, without limitation, Construction Equipment and Systems Equipment) and tools thereon owned by Contractor, may take assignment of the applicable Contractor’s agreements with Subcontractors, and may finish the applicable Work by whatever method Owner may deem expedient. If the costs of finishing the applicable Work exceed the unpaid balance of the Contract Price for such Work, then Contractor will pay the difference to Owner, subject to the provisions relating to limitations of liability and cost sharing set forth in this Agreement. Such right of termination for cause and right to take possession shall be in addition to and not in limitation of Owner’s other rights and remedies under the Agreement or, should Owner have exhausted any non-exclusive specific remedy under this Agreement, under law or equity.

23.6 Actions Upon Termination. Upon receipt of written notice from Owner of termination of this Agreement pursuant to either Section 23.4 or 23.5, Contractor will (i) cease operations as directed by Owner in the notice; (ii) take all actions necessary, including such actions as Owner may direct, for the protection and preservation of all Systems Equipment, Construction Equipment and the Systems (in whatever stage of completion); and (iii) terminate all existing subcontracts and purchase orders for the portion of the Work terminated (unless and to the extent Owner directs Contractor to assign such subcontracts and/or purchase orders to Owner pursuant to Section 23.4.3) and enter into no further subcontracts and purchase orders in connection with the Work.

23.7 Survival. Termination of this Agreement will not relieve Contractor of any obligation hereunder which expressly or by implication survives termination hereof, including, without limitation, its liabilities, warranties, and indemnification obligations under Article 28 with respect to any acts or omissions prior to the effectiveness of such termination or arising out of such termination.

24. ASSIGNMENT

Contractor may not assign its rights or obligations under this Agreement without the prior written consent of Owner. Owner may assign its rights and obligations under

this Agreement at any time to any future owner of the Facility and to any lender or other financing entity. When requested by Owner, Contractor will execute and return a consent to assignment in a form acceptable to such lender, financing entity or future owner. Subject to the foregoing, all of the rights, benefits, duties, liabilities and obligations of the Parties will inure to the benefit of and be binding upon their respective successors and permitted assigns.

This insurance includes the interests of Owner, Financing Parties and Contractor (including Contractor’s affiliates and Subcontractors). Owner shall provide to Contractor a certificate of insurance confirming the status of Contractor as an additional insured on the Project Builder’s Risk or All Risk Property Insurance policy. The Insurance policy shall provide for a waiver of all rights of subrogation against the Financing Parties and Contractor (including Contractor’s affiliates and Subcontractors). Contractor will be responsible for any deductible or self-insured retention under this insurance up to a maximum of (US$5,000,000) for each and every occurrence. The foregoing shall in no way affect Contractor’s obligation for any breach of the Warranty as described in the Terms and Conditions of the Agreement. The furnishing of said insurance by the Owner shall in no way relieve, or limit, or be construed to relieve or limit, the Contractor or Subcontractors of any tier of any other responsibility or obligation otherwise imposed by this Agreement.

25.2.2 Exclusion from Builder’s Risk. Contractor is aware that insurance companies providing “all-risk” Builder’s Risk insurance usually exclude several classes of unusual risk.

27.2 Sales Taxes. Owner will provide Contractor with a Maryland Exempt Use Affidavit, for the express purpose of allowing Contractor to use the Affidavit to procure Systems Equipment free of any and all sales or use taxes, in and outside of the State of Maryland. Should the Affidavit not be applicable to any item of Systems Equipment, then Contractor shall pay the tax due to the relevant taxing authority, and Owner shall reimburse Contractor for such tax in the Milestone Progress Payment applicable to the subject item of Systems Equipment. Such reimbursement shall be outside the EPC Total Compensation.

27.3 Property Taxes. Owner will be responsible for all property taxes assessed on the Site and on Systems Equipment. Contractor will be responsible for paying, and shall administer, any property taxes assessed against, or on, Construction Equipment.

28. INDEMNIFICATION

28.1 Property Damage. In addition to and not in limitation of its compliance with all Applicable Laws and Applicable Permits (including, without limitation, those relating to work and occupational safety and health measures) Contractor will take all reasonable precautions to avoid any damage to person or property at the Site or any adjacent areas due to its activities at the Site. Subject to Section 28.2, if Contractor or its Subcontractors cause any property damage at the Site during the course of the performance of the Work, and to the extent Owner is not reimbursed for such damages as an insured or an additional insured under any policy of insurance, then Contractor will bear the cost of same; provided, however, that for any such cost covered by Contractor’s insurance, the portion of such cost paid by Contractor as an insurance deductible shall be treated as Guarantee Cost pursuant to Section 11.3; provided further that the maximum amount of such costs that may be treated as Guarantee Costs shall be five hundred thousand dollars ($500,000) for each occurrence. If, in the reasonable opinion of Owner, Contractor has failed to fulfill its obligations under the foregoing sentence within a reasonable period of time, then Owner may repair or replace or cause to be repaired or replaced any damaged property and take all such actions as it deems necessary in order to return the affected part of the Site or any adjacent areas to the condition in which they were in prior to such damage. All costs and expenses related to such actions of Owner will be for the account of Contractor, and Contractor will promptly reimburse such amounts to Owner, subject to the limitation set forth in Section 28.2 and Article 21. Owner’s taking such actions will not relieve Contractor of its obligations under this Agreement and Applicable Laws or constitute a waiver of any of Owner’s rights or a mitigation or diminution of any of Contractor’s obligations under this Agreement.

100

Contractor understands and agrees that it shall not interfere, and shall coordinate and cooperate, with the Owner, Owner’s Separate Contractors and other contractors at the Project Site to fully perform the Work with no or minimal impact to any other party.

28.2 Limitation on Property Damage Indemnification. Notwithstanding anything to the contrary, Contractor’s liability for damage to the Work under Section 28.1 shall be limited to the deductible of the Builders All Risk and Liability Insurance to be procured by Owner pursuant to Section 25.2 hereunder, and Contractors Liability for damage to the existing Facilities shall be limited to the deductible of Owner’s property insurance. To the extent that Contractor damages any personnel or property of another Owner authorized party at the Project Site by or through its negligence, and such damage is not covered by any applicable insurance policy, then Contractor shall be and remain liable for such damage.

28.3 Royalties and License Fees. Contractor will pay all royalties, license fees and the like, if any, for any tangible or intangible property or software or any other intellectual property rights including, without limitation, materials, methods, processes and systems used, purchased or provided by or on behalf of Contractor for incorporation into a System.

28.4 Operation of Systems. The operation and maintenance of the Systems will be within the exclusive control of Owner. The Parties acknowledge that, in operating and maintaining the Systems, Owner will be following the instructions set forth in the operating and maintenance manual provided to Owner by Contractor under Section 6.5.6.

28.5 No Liens or Encumbrances. Contractor warrants and guarantees that good and clear title to the Systems, the Systems Equipment and all materials and supplies provided pursuant to this Agreement will pass to Owner free and clear of all claims, liens, security interests and other rights and encumbrances.

Contractor hereby assumes liability for, and will indemnify, defend and hold harmless Owner Indemnitees from and against liability (including any strict liability), claims, suits, actions, costs (including attorneys’ fees), expenses, losses or judgments that may be imposed on, incurred by or asserted against any Owner Indemnitee arising out of (i) the release or threatened release by Contractor or its Subcontractors, of any Hazardous Substances on the Site or any areas adjacent thereto that are brought onto the site by Contractor or its Subcontractors, (ii) the violation by Contractor or its Subcontractors of any Applicable Laws and/or Applicable Permits, (iii) any claim or allegation that any Systems Equipment, Construction Equipment or other equipment, materials or information provided by Contractor or any Subcontractor in connection with its performance of the Work constitutes an infringement of any patent, trade mark, trade secret or confidential information, copyright or proprietary rights of any kind belonging to or claimed by any third party, or (iv) any Subcontractor liens, claims of lien or similar encumbrances arising in connection with any Subcontractor claims.

28.8 No Limitation to Workers’ Benefits. In any and all claims against any Owner Indemnitee or any of their agents or employees by any employee of Contractor or any Subcontractor, the indemnification obligation under Section 28.6 above will not be limited in any way by any limitation on the amount or type of damages, compensation or benefits payable by or for Contractor or any Subcontractor under workers’ or workmen’s compensation acts, disability benefit acts or other employee benefit acts.

29. GOVERNING LAW

This Agreement will be governed in all respects by the laws of the State of New York, U.S.A. without giving effect to any choice of law ruled thereof which may direct the application of the laws of another jurisdiction. Subject to the Dispute resolution Article 33, any action arising out of, or related to, this Agreement or the Project shall be brought in a court of competent jurisdiction sitting in the Borough of Manhattan, City of New York, New York, U.S.A. and the Parties consent to jurisdiction and venue in such court.

30. PERMITTING

30.1 Responsibility for Permitting. Responsibility for permitting is set forth in Exhibit 4.

For permits for which Contractor is responsible, Owner shall provide reasonable assistance in support of Contractor’s application for such Applicable Permits.

102

30.1.1 Owner’s Permits Required for Construction. With respect to each FGD System, Owner shall obtain all permits as required for construction for which it is responsible on or before September 1, 2007. Should Owner fail to obtain such permits by such date, then by Change Order pursuant to Sections 19.7 and 19.13, and subject to Section 19.16, the milestone identified in Exhibit 15 as “Ready for Flue Gas to Scrubber” and the Guaranteed Provisional Acceptance Date for such System shall each be extended day-for-day for each day of delay in obtaining such permits.

30.1.2 Permission to Begin Installation of Pilings With respect to each FGD Systems, Owner shall use good faith efforts to obtain permission for Contractor to begin installing the necessary piles at the Site on or before August 1, 2007. Should Owner fail to obtain such permission, then by Change Order pursuant to Sections 19.7 and 19.13, and subject to Section 19.16, the milestone identified in Exhibit 15 as “Ready for Flue Gas to Scrubber” and the Guaranteed Provisional Acceptance Date for such System shall each be extended day-for-day for each day of delay in obtaining such permission.

30.2 Other Permits. To the extent that any permits are required that are not listed in Exhibit 4, then Owner will obtain and pay for all environmental and operating permits, and Contractor will obtain and pay for all construction permits.

31. SITE CONDITIONS

31.1 Geotechnical Study. The Contractor shall perform and have full responsibility for the comprehensive geotechnical study (the “Geotechnical Study”) which shall indicate the results of Contractor’s full investigation, discovery, and conclusions regarding the subsurface conditions and all other geotechnical issues at the Site. The findings and conclusions of the Geotechnical Study shall be incorporated into the design of the Project.

31.2 Special Site Characteristics. Prior to issuance of NTP, Contractor shall thoroughly inspect the Site and fully familiarize itself with the structures, features, characteristics and conditions of the available working space and the ongoing operations of the Facility. Contractor shall ascertain the most suitable means and methods for executing and delivering the Work in accordance with this Agreement, and shall employ such means throughout its performance of the Work.

31.3 Contractor’s Knowledge of Conditions. Contractor will be responsible for having taken all steps necessary to ascertain the suitability of the location of the Work, and the general and local conditions which may affect the Work or the scheduling or cost thereof. Failure by Contractor to fully acquaint itself with all conditions which may affect the Work, such as transportation, handling, storage of materials, normal weather patterns and ambient conditions, Applicable Laws, Applicable Permits, Taxes, insurance, and the character and availability of labor, consumables, supplies, Systems Equipment,

103

Construction Equipment, the nature and timing of work being performed by other contractors and the facilities needed preliminary to and during the performance of the Work, will not relieve Contractor of its responsibilities under this Agreement.

31.4 Sub-Surface Site Conditions. Contractor agrees that each Site is or will be made by Contractor satisfactory for performance of the Work in accordance with the Approved Project Schedule and for the Contract Price (except as the Approved Project Schedule and Contract Price may be adjusted in accordance with Article 19). Contractor expressly assumes the risk of any sub-surface conditions relating to soils, water, or rock that may affect the performance of the Work that could reasonably have been deduced from or revealed by the Geotechnical Study described in Section 31.1 of this Agreement.

32. SUBCONTRACTORS

32.1 Approved Subcontractors. Owner will have the right to approve any and all Subcontractors from whom Contractor or its Subcontractors may obtain bids to subcontract portions of the Work. In no case shall Owner’s approval of any subcontract impose on Owner any responsibility for the Work or relieve Contractor of any of its obligations under this Agreement. Owner’s approval of Contractor’s proposed Subcontractors of any tier will not be unreasonably withheld. If Contractor receives a disapproval notice for any Subcontractor it shall not use or utilize such Subcontractor. Those approved Subcontractors are listed in Exhibit 1. Contractor may also have portions of the Work performed by its affiliates, in which event the Work shall be awarded by competitive sourcing and shall be subject to all provisions of Article 10.

32.2 Subcontractor and Vendor Identification. Prior to issuance of the NTP, Contractor shall identify all equipment and erection Subcontractors or potential Subcontractors that Contractor will employ to complete the Work. Contractor shall not add any additional Subcontractors after issuance of the NTP without Owner’s prior approval.

32.3 Substitute Contractors. If Contractor proposes to substitute a non-preapproved subsupplier, the subsupplier’s credentials shall be submitted to Owner for approval. Sufficient data must be provided to Owner in a timely manner to prove that the proposed equipment is of an equivalent quality and has proven operation in similar service conditions, including capacity, to that provided by the pre-approved subsuppliers. If an offshore subsupplier is proposed, contractor shall provide information providing satisfactory domestic stockpiling of any required spare parts.

32.4 Purchase Orders and Subcontracts. Except as otherwise expressly agreed or directed by Owner, Contractor will ensure that each Subcontractor with whom Contractor has a direct contract is bound to Contractor to the same extent that Contractor is bound to Owner hereunder. Contractor will use in connection with the Work such Contractor-prepared purchase orders, contracts, subcontracts, material requisitions, terms and conditions and similar purchasing forms as are generally used from time to time by Contractor, however, these forms shall be designed to facilitate an Open Book analysis of

104

underlying costs related to the Work. As a condition to Final Completion, Contractor will provide Owner with copies of all purchase orders, contracts, subcontracts and material requisitions relating to such System (unpriced for any Work being performed on a lump sum pricing method). Contractor shall purchase the DCS equipment and software on the terms and conditions for purchase of same by Owner pursuant to the Master Agreement between Mirant Services LLC and Invensys Systems, Inc dated March 26, 2007, (the “DCS Master Agreement”) a copy of which was provided to Contractor prior to the Effective Date. Contractor’s responsibility to Owner under this Agreement for the DCS equipment shall be equal to but no higher than the obligations of the DCS Contractor for the DCS Equipment under the DCS Master Agreement.

32.5 Subcontractor Warranties. Except as otherwise expressly agreed or directed by Owner in writing, Contractor will procure from suppliers standard warranties and guarantees with respect to the Systems Equipment. Notwithstanding any failure of Contractor to obtain such a warranty from a supplier, the Parts and Labor Warranty shall apply to all Systems Equipment. If, and to the extent, that Owner is not able to effectuate a warranty remedy from the Contractor, where Contractor has subcontracted such services, then Owner may contact and prosecute such warranty services from such Subcontractor. As a condition to the achievement of Final Completion, and/or prior to the termination of this Agreement, Contractor will (i) assign in writing all such warranties and guarantees to Owner; (ii) secure any consents necessary for such assignment from each Subcontractor; and (iii) deliver to Owner copies of all contracts and subcontracts (unpriced for any Work being performed on a lump sum pricing method) providing for warranties and guarantees enforceable by Owner. Neither Contractor, nor its Subcontractors will take any action which could release, void, impair or waive any warranties or guarantees on Systems Equipment, materials or services that it procures from others.

32.6 Subcontractor Insurance. Except as otherwise agreed or directed by Owner in writing, Contractor will require all Subcontractors with whom Contractor has a direct contract to obtain, maintain and keep in force (and to require from their lower tier Subcontractors to obtain, maintain and keep in force) during the time in which they are engaged by Contractor similar insurance coverages, if and as applicable to their respective scopes of services and activities as are required of Contractor pursuant to Section 25.1. The limits for such coverage may be reduced by the Contractor in which case the Contractor agrees to be solely responsible to Owner, the Financing Parties, claimants or employees for any otherwise un-recovered losses which fall in the area between the required Subcontractor coverage and that which is actually procured and maintained. Furthermore, Contractor will require of its subcontractors that the policies providing such coverages meet the same requirements as are applicable to Contractor’s policies, as set forth in Article 25.

32.7 No Privity with Subcontractors. Other than subsequent to an assignment of a subcontract or purchase order to Owner, Owner will not be deemed by virtue of this Agreement or otherwise to have any contractual obligation to or relationship with any Subcontractor. Furthermore, no Subcontractor will have any rights against Owner under

105

this Agreement, whether as a third party beneficiary or otherwise. Contractor will include clauses that expressly state the concepts set forth in this Section 32.7 in each subcontract with Subcontractors.

32.8 Assignment of Subcontracts to Owner. In the event of termination of this Agreement pursuant to its terms, Contractor shall assign any or all of its agreements with Subcontractors to Owner at Owner’s request and shall ensure that each such subcontract is assignable to Owner. In the event of partial termination of this Agreement pursuant to its terms, Contractor shall assign the applicable agreements with Subcontractors to Owner at Owner’s request and shall ensure that each such subcontract is assignable to Owner

32.9 Directed Payments. From the monies paid by Owner to Contractor, Contractor shall make payment to Subcontractors, to utilities furnished and Taxes owed by Contractor, to the payment of premiums on surety bonds and insurance, and to any other purpose related to the Project. The Contractor agrees that any liquidating agreement, pass-through agreement, or other agreement between the Contractor and a Subcontractor that purports to make Owner responsible for paying a Subcontractor for work on the Project is void and unenforceable and deemed to be waived.

32.10 Neglect to Pay. Should Contractor neglect or refuse to pay promptly when due any legitimate or undisputed bill incurred by it pursuant to the Agreement, Owner, after giving Contractor seven (7) calendar days’ notice of its intentions so to do, shall have the right but not the obligation, to pay such bill by joint check made payable to Contractor and the applicable Subcontractor and such payments shall be accounted for as a payment to Contractor. Owner shall be entitled to offset such amounts against any payments thereafter becoming due to Contractor. The payment of any bill by Owner pursuant to the foregoing shall not be deemed to cure or waive Contractor’s default, and Owner may exercise any other right or remedy granted by the Agreement or by law or equity. Owner will not make any such payment, however, without prior consultation with Contractor concerning Contractor’s reason for refusing to pay such bill.

33. DISPUTE RESOLUTION

33.1 Applicability of Resolution Procedures. All claims, disputes or other matters in question between the Parties arising out of or relating in any way to this Agreement (“Disputes”) will be resolved pursuant to this Article 33.

33.2 Management Discussions. The Parties agree to make a diligent, good-faith attempt to resolve all Disputes. If the Authorized Representatives of the Parties are unable to resolve a Dispute arising under this Agreement within ten (10) calendar days after notice from one Party to the other, such Dispute will be submitted promptly to the senior executive officers of the Parties, who will meet, in person or by telephone, not later than ten (10) calendar days after the date such Dispute was submitted to them. In the event that the officers cannot resolve the Dispute within five (5) Business Days after the matter is submitted to them, then, unless otherwise agreed, the Parties will refer such Dispute to mediation proceedings under Section 33.3.

106

33.3 Mediation. Provided that the Parties have been unable to resolve a Dispute pursuant to the procedures set forth in Section 33.2, the Parties will make a good faith effort to mediate a resolution of the dispute with the assistance of a qualified mediator to be chosen by agreement of the Parties. In the event that the Parties are unable to agree upon a qualified mediator, a mediator will be designated by the American Arbitration Association (“AAA”). Any such mediation will be held in accordance with the Construction Industry Mediation Rules of the AAA or by such other standards as established by the mediator. Such mediation will be held in Atlanta, Georgia or at such other site as the Parties may agree. If, despite the Parties’ good faith efforts to mediate a Dispute, such Dispute remains unresolved forty-five (45) calendar days after the first date on which such mediation commenced (or such longer period as the Parties may agree to in writing), then the Parties may pursue such rights and remedies as may be available under applicable law.

33.4 Arbitration. Should a mediation under Section 33.3 be unsuccessful, and so long as the aggregate amount of all disputed Changes, Change Order Notices, Change Order Requests, Change Orders, and other Disputes, claims, controversies or other matters disputed in good faith between the Parties at one time is equal to or less than twenty-five million dollars ($25,000,000), then all such Disputes, controversies or claims arising out of or related to the Project shall be settled by mandatory and binding “baseball” arbitration in accordance with this Section 33.4, and judgment upon the award may be entered in any court having jurisdiction thereof; provided, however, that should such aggregate amount exceed twenty-five million dollars ($25,000,000), then arbitration shall not be mandatory and the Parties may elect, by mutual agreement in writing, to have none, any or all such Disputes, controversies or claims decided by binding or non-binding arbitration, as may be agreed by the Parties. The Parties agree that they will not assert frivolous claims in bad faith in an effort to subvert the purpose of the preceding sentence, which is to establish an objective standard for distinguishing between situations in which arbitration is mandatory, and situations in which arbitration is not mandatory and will be used only upon agreement of the Parties. Any arbitration pursuant to this Section 33.4 shall be held in Atlanta, Georgia and conducted pursuant to the Uniform Arbitration Act (2000). The arbitration shall be heard by three arbitrators, who shall be appointed using the process for the selection of the members of the DRB, and who shall strictly enforce the terms and conditions of this Agreement. In the event of such arbitration, each Party agrees to produce to the other Party all non-privileged documents that such other Party considers to be related to the Dispute, including all electronic documents and data in native format. Provided that the other Party is provided a reasonable opportunity to obtain and preserve such electronic data before a Party ceases to maintain it, the requirement that data be provided in native format shall apply only so long as that electronic data is still maintained in the ordinary course of business. All such documents shall be produced at least six months before the date set for the hearing, and the initial production shall be supplemented promptly to include any additional documents that come into possession of a Party after the initial production. Each Party shall also provide to the other Party, at least forty-five (45) days before the hearing or such shorter period as the arbitrators may direct upon application of a Party (but not less than 30 days before the

107

hearing), (i) a copy of all exhibits the Party will introduce at hearing, and a (ii) complete list of all witnesses the Party may call and a detailed summary of their testimony, including a written report of all expert witnesses in accordance with Fed. R. Civ. P. 26(a)(2)(B). Documents that have not previously been exchanged, and witnesses for whom proper information has not previously been provided, may not be considered by the arbitrators without a showing of good cause. The attorneys for the Parties and the arbitrators shall have the authority to issue subpoenas for the appearance of witnesses at the hearing and for production of documents (including documents in the possession of persons other than the Parties) at or in advance of the hearing. At least fifteen (15) days before the date set for the hearing, the Parties will exchange, and provide to the arbitrators, best and final offers of compromise, which the Parties may amend at any time before the tenth (10th) day after the close of the hearing. Within forty-five (45) days after the conclusion of the hearing, the arbitrators shall select the best and final offer (as amended) of one Party and that offer shall become the award of the arbitrators. At the discretion of Owner, any Subcontractor with whom the Contractor has a direct contract may be joined as a party to an arbitration conducted pursuant to this Section 33.4. Contractor shall include in each of its subcontracts, to the extent commercially practicable, a provision allowing for such joinder at Owner’s discretion, and an agreement by the Subcontractor to be bound by the results of such arbitration. Should any Subcontractor oppose the inclusion of such provisions in its subcontract, and should the negotiations between Contractor and such Subcontractor reach an impasse, Contractor will consult with Owner to determine a commercially reasonable course of action before entering into a subcontract or issuing a purchase order to such Subcontractor.

33.5 Dispute Review Board. Notwithstanding Sections 33.3 and 33.4, either Party may, at any time, submit a Dispute for interim decision by the Dispute Review Board (“DRB”) in accordance with Exhibit 17. Should a Dispute arise that involves the subject matter of Sections 8.6, 19.15, 23.3 33.5, 12.3.5 or 12.6.4, then the Parties agree to abide by any decision of the DRB relating to same on an interim basis, until the disagreement can be permanently resolved through the procedure described in this Article 33. The Parties agree that the Parties will suffer irreparable harm if either Party does not abide by a decision of the DRB relating to the Sections listed in the previous sentence, and that either Party may enforce such a decision of the DRB through an action for equitable relief including mandatory temporary injunction.

33.6 Obligations Continue. Notwithstanding the existence of any Dispute hereunder, the Parties will continue to perform their respective obligations under this Agreement unless the Parties otherwise mutually agree in writing. If during the pendency of a Dispute, the Work is in progress, Owner’s Authorized Representative will give such instructions as are necessary for the proper performance of the Work and to prevent delays pending settlement of the Dispute. Contractor will carry out such instructions and will proceed with the execution of the Work, it being understood that in so doing Contractor, if it gives Owner a written notice before carrying out such Work that Contractor is doing so under protest, is not jeopardizing any claim it may have and is not in any way renouncing or waiving any rights or recourses.

108

33.7 Injunctive Relief. Notwithstanding anything in this Agreement to the contrary, nothing in this Agreement is intended to, nor shall it, prevent the Parties from seeking injunctive relief at any time as may be available under law or in equity.

33.8 Survival. The provisions of this Article 33 will survive the termination of this Agreement.

34. MISCELLANEOUS

34.1 Audit and Maintenance of Records.

Within fifteen (15) business days after delivery of the notice of the Owner Caused Project End Suspension, Owner shall deposit into a specific escrow account an amount equal to one hundred percent (100%) of the amount of retention related to completed and undisputed milestones.

Notwithstanding the foregoing, should (i) the time limits imposed by the DEC or any other regulatory agencies related to the Facilities for one or more of the Facilities be extended; (ii) Owner intentionally interferes with or frustrates Contractor’s efforts to achieve Provisional Acceptance, Substantial Completion or Final Completion within the time provided in the Approved Project Schedule; and (iii) Contractor demonstrates that, at the time of the interference, Owner had a financial incentive to pursue recovery of liquidated damages for late completion rather than allow Contractor to complete the Work within the time allowed, then for the time period of such Owner interference, Contractor shall not be assessed any liquidated damages relating to Provisional Acceptance, Substantial Completion or Final Completion within the time provided in the Approved Project Schedule.
