In no event shall Contractor’s representatives on the Program Labor Committee request an escalation in Craft Labor Compensation in order to improve the Project Schedule, or to recover the Project Schedule based upon conditions unrelated to craft labor availability, and in connection with any request for escalation, Contractor’s representatives shall reasonably demonstrate that the requested escalation in Craft Labor Compensation is necessary in order for Contractor to attract or retain sufficient qualified craft labor personnel to perform the on-Site Work as necessary for Contractor to maintain the Project Schedule.

6. TERMS OF PAYMENT. Payments to Contractor shall be made as follows:

6.1 Invoice Payments. Subject to Owner’s right to withhold payments as provided in this Article 6, Owner shall make payments to Contractor in accordance with Sections 6.3 and 6.7, and Section 6.5 with respect to the Subcontractor Invoices. Contractor shall be paid on a reimbursable cost basis with respect to Work performed during the Open Book Review, and after the Open Book Review is completed and the Separated Contract Price has been agreed upon by the Parties, in accordance with the Schedule of Payment Values for each of the Units in accordance with Exhibit A-1–Section 01320 as set forth in Exhibit D less the amount of any payments made to Contractor during the Phase One EPC. After completion of the Open Book Review, each Invoice Payment shall be due and payable only to the extent it is supported by signed notices of completion of Schedule of Payment Values or other milestones pursuant to Section 6.2. No Invoice Payment shall be made to the extent of any improperly performed Work.

6.2 Progress Assessment. After completion of the Open Book Review, Contractor shall from time to time notify Owner’s Project Representative upon completion of each Schedule of Payment Values milestone for signature by Owner’s Project Representative or designee, such signature not to be unreasonably withheld.

6.3 Contractor’s Invoices.

6.3.1 During Open Book Review. During the period before completion of the Open Book Review, on or about the first (1^st) day of each month, Contractor shall furnish Owner two (2) copies of its Contractor’s Invoice covering the estimated cost of the Work to be completed during the next succeeding twenty (20) days, on an estimated reimbursable cost basis. After the initial invoice, each subsequent invoice shall reflect the total amount of the Work completed to date, plus the Work to be completed through the first twenty (20) days of the current month, less the total amount paid through the last invoice period. Each Contractor’s Invoice shall separate the Work to be completed as represented by such invoice into engineering services, construction services and costs of equipment, shall be reasonably detailed and shall be accompanied by reasonable supporting documentation with respect to the Work completed and the costs related thereto set forth on such invoice. Notwithstanding anything to the contrary in Sections 6.3.2 or 6.7, until completion of the Open Book Review, Contractor shall invoice Owner and Owner shall make payments to Contractor with respect to the Subcontractors in accordance with Section 6.5. Contractor acknowledges and agrees that Owner may request the Contractor’s Invoices be submitted in electronic form and agrees to use commercially reasonable efforts to comply with Owner’s reasonable requests for the use of electronic invoices.

6.3.2 After Completion of Open Book Review. Beginning on the first (1^st) day of the month after the month in which the Open Book Review Period is completed, and on or about the first (1^st) day of each month thereafter, Contractor shall submit two (2) copies of its Contractor’s Invoice for the Work completed on each Unit in the immediately preceding month in the form of Exhibit F to Owner by delivering one such copy to the Project Representative and such Person in the finance or accounting department as designated in writing by Owner. Contractor acknowledges and agrees that Owner may request the Contractor’s Invoices be submitted in electronic form and agrees to use commercially reasonable efforts to comply with Owner’s reasonable requests for the use of electronic invoices. Contractor specifically agrees that it shall not request in any Contractor’s Invoice the payment of any sum attributable to Work: (a) for which Contractor has already been paid; (b) which has been rejected by Owner or Contractor and has not subsequently been accepted in accordance with the terms hereof; or (c) for which Contractor and Owner have not signed a notice of completion of a Schedule of Payment Values milestone as provided in Section 6.2. Each Contractor’s Invoice: (x) shall identify: (i) which activities described on the Schedule of Payment Values have been completed; (ii) the related payments set forth on the Schedule of Payment Values that are then due as of the end of the immediately preceding calendar month; (iii) any other amounts then payable by Owner to Contractor under Article 16 or any other provision hereof; (iv) shall be accompanied by reasonable supporting documentation with respect to the Work completed; (v) shall not limit Owner’s right to dispute any amounts requested for payment; (y) shall include the notices of completion of Schedule of Payment Values milestones signed during the preceding month; and (z) shall include a Conditional Waiver and Release Upon Milestone or Progress Payment of Contractor for payments to be made pursuant to such Contractor’s Invoice. Contractor understands and agrees that any Contractor’s Invoice that is inaccurate or incomplete or that lacks reasonable detail, specificity, or supporting documentation required by this Section 6.3, Section 6.4, Section 6.5 and, with respect to a Contractor’s Invoice requesting a Final Payment, Section 6.9, shall not, to the extent of such deficiency, constitute a valid request for payment.

EXECUTION COPY

6.4 Subcontractor Statements. In addition to the requirements of Section 6.3 and 6.5, with each applicable Contractor’s Invoice, or each invoice received from a Subcontractor prior to the Open Book Review and delivered to Owner pursuant to Section 6.5, Contractor shall submit to Owner from each of Contractor’s direct (i.e. first tier) Major Subcontractors, and shall use its commercially reasonable efforts to obtain and submit from each other Major Subcontractor: (a) unless the applicable Major Subcontractor has already delivered a Conditional Waiver and Release Upon Final Payment, a Conditional Waiver and Release Upon Milestone or Progress Payment, and (b) if such Major Subcontractor has completed all Work that such Major Subcontractor is to perform, an Unconditional Waiver and Release Upon Final Payment; provided, however, if Contractor is unable to obtain the foregoing, Contractor may provide Owner with a bond or other security in form, substance and amount reasonably acceptable to and if reasonably requested by Owner based on the existence of outstanding claims, if any, with such Major Subcontractor, to indemnify Owner against and discharge any lien or other claim by such Major Subcontractor with respect to its right to be paid in connection with performance of the Work. Contractor shall provide Owner with a list of Contractor’s direct (i.e., first tier) Major Subcontractors and its other Major Subcontractors as soon as practicable after the date hereof and from time to time thereafter to reflect changes in such list, but no less than monthly on the same date that Contractor’s Invoice is delivered to Owner if there have been any changes to such list in the prior month, by delivering one copy of such list to the Project Representative and one copy to such Person in the finance or accounting department as designated in writing by Owner.

6.5 Subcontractor Invoices. Prior to completion of the Open Book Review, Contractor shall submit two (2) copies of any invoices received from its Subcontractors to Owner by delivering one such copy to the Project Representative and such Person in the finance or accounting department as designated in writing by Owner pursuant to Section 6.3. Each such invoice shall be reasonably detailed and shall be accompanied by reasonable supporting documentation with respect to the Work completed and the costs related thereto set forth on such invoice, and by the statements required pursuant to Section 6.4. Contractor acknowledges and agrees that Owner may request such invoices be submitted in electronic form and shall use commercially reasonable efforts to obtain the Subcontractors’ compliance with such requests. Contractor understands and agrees that any invoice that is inaccurate or incomplete or that lacks reasonable detail, specificity, or the supporting documentation required by this Section 6.5 shall not, to the extent of such deficiency, constitute a valid request for payment. By submitting such invoice to Owner, Contractor shall be deemed to represent to Owner that the milestone required for payment has been achieved or the Work required to be completed has been completed, as applicable. Notwithstanding anything to the contrary in Section 6.3, Owner shall pay Contractor the entire amount of the invoice, subject only to Retainage, in immediately available funds by electronic means using banking transfer instructions provided by Contractor within fifteen (15) days after Owner receives such invoice.

6.6 Owner Review. Without limiting Owner’s rights of review under Article 11, within ten (10) days after Owner receives a Contractor’s Invoice and all accompanying documentation required by Sections 6.2 and 6.4, Owner shall notify Contractor concerning any dispute over the accuracy of the submitted invoice and the basis for such dispute. Disputed invoices or portions thereof that are corrected before the date that is five (5) days prior to the date payment is due pursuant to Section 6.7, shall be paid on such due date.

EXECUTION COPY

6.7 Payments. Within twenty (20) days after receipt of a Contractor’s Invoice (except as otherwise provided in Section 6.5), Owner shall pay, subject to Sections 6.8 and 6.12, all undisputed amounts that are then payable as set forth in the then current Contractor’s Invoices (each, an “Invoice Payment”). Owner and Contractor agree that payment of amounts due under this Agreement may be by electronic means of immediately available funds using banking transfer instructions provided by the receiving Party of any such payment at least five (5) business days before such payment is due and payable. Upon receipt of any Invoice Payment from Owner, Contractor shall promptly pay each Subcontractor out of such Invoice Payment the amount to which said Subcontractor is entitled pursuant to the applicable subcontract or purchase order. Owner shall not have any obligation to pay any Subcontractor with respect to the Work completed by such Subcontractor on the Project. Any delinquent payment shall bear interest at the prime rate as published in “The Money Rates” Section of The Wall Street Journal (U.S. Edition), plus one percent (1%) per annum, until paid, but not to exceed the maximum rate permitted by the applicable usury laws. The payment of interest unaccompanied by payment of the delinquent payment shall not excuse or cure any default or delay in such payment. In the event interest accrues on any delinquent payment, Contractor shall reflect such amount in each subsequent billing invoice.

6.8 Retainage.

6.8.1 Retainage. Owner shall withhold from each Invoice Payment for a Unit an amount (the “Retainage”) equal to five percent (5%) of the portion of the Separated Target Price or the Separated Contract Price, as applicable, to be paid for the applicable month pursuant to Contractor’s Invoice. In the event Contractor’s, or if applicable its guarantor’s, rating falls below BBB- by Standard & Poors or Baa3 by ▇▇▇▇▇’▇, Owner shall be entitled to withhold additional Retainage of five (5%) for a total Retainage of ten percent (10%) from Contractor’s Invoices submitted after such decline in Contractor’s or its guarantor’s rating.

6.8.2 Letter of Credit. Notwithstanding the obligations set forth in this Section 6.8 regarding Retainage or Section 6.12 regarding Owner’s right to holdback or withhold payment, Contractor may provide in lieu of Retainage, or receive a refund of the Retainage (if cash Retainage has already been withheld) and amounts withheld by Owner pursuant to Section 6.12, upon delivery of an irrevocable standby letter of credit whereupon Owner shall no longer maintain such cash Retainage and shall pay such amounts withheld pursuant to Section 6.12 to the extent covered by such Letter of Credit. If Contractor desires to deliver one or more Letters of Credit, Contractor shall, at its own expense, cause a financial institution that has senior unsecured debt rated at least A by Standard & Poor’s or A2 by ▇▇▇▇▇’▇ (or an equivalent rating from such other equivalent rating agency as may be approved by Owner) to issue and maintain, by renewal or replacement, for the periods specified herein, one or more irrevocable, unconditional, transferable, standby, revolving letters of credit in favor of Owner consistent with the requirements of this Section 6.8.2, in form and substance as set forth on Exhibit P herein (individually and collectively, the “Letter of Credit”). If the amount of such Letters of Credit are insufficient to cover the Retainage with respect to the Contractor’s Invoices, Owner shall be entitled to withhold cash Retainage and such amounts as Owner may be entitled to withhold pursuant to Section 6.12 from payments made with respect to such Contractor’s Invoice. The terms of release of Retainage as set forth in Section 6.8.3 and payment with respect

6.8.3 Release of Retainage. Owner shall release the Retainage to Contractor as follows:

6.8.3.1 Release at Substantial Completion. No later than eighty (80) days after achieving Substantial Completion of a Unit, or if a pre-lien notice pursuant to Section 53.056 of the Texas Property Code, has been received by Owner, one hundred twenty (120) days after such Substantial Completion Date, Owner shall release to Contractor an amount of Retainage equal to fifty percent (50%) of the amount retained to date related to such Unit; provided that Contractor is on schedule to achieve Substantial Completion by the Substantial Completion Guaranteed Date for the remaining Unit and is not otherwise in default under the terms of this Agreement. If Retainage is not released following Substantial Completion of the first Unit because Contractor is not on schedule to achieve the Substantial Completion Guaranteed Date of the second Unit, Owner shall release such fifty percent (50%) Retainage related to the first Unit within fifteen (15) days after the earlier of the date Contractor reasonably demonstrates it is back on schedule to achieve Substantial Completion by the Substantial Completion Guaranteed Date for the remaining Unit or Contractor achieves Substantial Completion of the second Unit; provided that Contractor is not otherwise in default under the terms of this Agreement. If Retainage is not released upon Substantial Completion of a Unit due to Contractor being in default under the terms of this Agreement, Owner shall release such fifty percent (50%) Retainage related to the first Unit within ten (10) days after Contractor reasonably demonstrates that such default has been cured; provided that Contractor is on schedule to achieve Substantial Completion by the Substantial Completion Guaranteed Date for the remaining Unit. Concurrently with Owner’s release of Retainage pursuant to this Section 6.8.3.1, Owner shall provide to Contractor, or take any actions to cause the financial institutions holding any Letters of Credit, written confirmation of the amounts released under this Section 6.8.3.1.

6.8.3.2 Release at Final Completion. Within eighty (80) days (one hundred twenty (120) days if Owner receives a pre-lien notice pursuant to Section 53.056 of the Texas Property Code before or during such eighty (80) day period) after the Final Payment for a Unit, and subject to compliance with and completion of all requirements regarding reports, audits and closeout reports as set forth in Section 21.1.11 by Contractor and each Subcontractor enrolled in the OCIP, Owner shall release to Contractor all of the amount retained to date related to such Unit then held by Owner; provided that if such Retainage is related to Invoice Payments for the first Unit to be completed, whether ▇▇▇▇ ▇ or Unit 2, Contractor is on schedule to achieve the Substantial Completion Guaranteed Date for the other Unit and is not otherwise in default under the terms of this Agreement. If Retainage is not released following Final Completion of the first Unit because Contractor is not on schedule to achieve the Substantial Completion Guaranteed Date of the second Unit, Owner shall release such Retainage related to the first Unit within fifteen (15) days after the earlier of the date Contractor reasonably demonstrates it is back on schedule to achieve the Substantial Completion Guaranteed Date for the remaining Unit or Contractor achieves Substantial Completion of the second Unit; provided that Contractor is not otherwise in default under the terms of this Agreement. If Retainage is not released upon Final Completion of a Unit due to Contractor being in default under the terms of this Agreement, Owner shall release the remaining Retainage related to the first Unit within ten (10) days after

EXECUTION COPY

Contractor reasonably demonstrates that such default has been cured; provided that Contractor is on schedule to achieve the Substantial Completion Guaranteed Date for the remaining Unit.

6.8.3.3 Release upon Termination. In the event this Agreement is terminated prior to completion of the Work for any reason other than a Contractor Event of Default, all Retainage on payments made to Contractor prior to such termination shall be released to Contractor upon the later to occur of (a) eighty (80) days (one hundred twenty (120) days if Owner receives a pre-lien notice pursuant to Section 53.056 of the Texas Property Code before or during such eighty (80) day period) after the date of such termination, and (b) ten (10) days after all disputes between Owner and Contractor have been resolved and all amounts due from Contractor have been paid (as applicable); provided that in each case Contractor and each of its direct (i.e., first tier) Major Subcontractor has delivered, and that Contractor has used commercially reasonable efforts to cause each of its other Major Subcontractors to deliver, Unconditional Waivers and Releases Upon Final Payment to Owner prior to such release of the Retainage.

6.9 Final Payment. Upon the delivery of Owner’s Certificate of Final Completion of a Unit, Contractor shall submit a final Contractor’s Invoice for such Unit (a “Final Contractor’s Invoice”) which shall set forth all amounts due to Contractor that remain unpaid in connection with such Unit (including amounts relating to the items on the Punchlist for such Unit), and shall attach all reports required of Contractor and each Subcontractor enrolled in the OCIP pursuant to Section 21.1. Upon approval of such Final Contractor’s Invoice by Owner based on Contractor having performed its Work in accordance with this Agreement, Owner shall pay to Contractor the amount due under such Final Contractor’s Invoice (“Final Payment”). Owner shall make Final Payment to Contractor within thirty (30) days after receipt of the Final Contractor’s Invoice if and only if Contractor has delivered the following items to Owner:

(a) with respect to each Major Subcontractor, either:

(i) an Unconditional Waiver and Release Upon Final Payment of Subcontractor; or

(ii) a bond in form and substance reasonably acceptable to Owner to indemnify and fully protect Owner against any claim by such Subcontractor with respect to its right to be paid in connection with the Project or the performance of the Work;

(b) with respect to Contractor and each Subcontractor enrolled in the OCIP, completion of all requirements regarding reports, audits and closeout reports in connection with the OCIP under Section 21.1; and

Contractor covenants that it shall deliver to Owner an Unconditional Waiver and Release Upon Final Payment no later than two (2) Business Days after Contractor’s receipt of Final Payment. Concurrently with Owner’s release of Retainage pursuant to Section 6.8.3.2, Owner shall surrender to Contractor, or take such actions as reasonably necessary to cause such surrender of, any Letter(s) of Credit held in lieu of Retainage.

EXECUTION COPY

6.10 Method of Payment. All payments to be made to Contractor under this Agreement shall be paid in Dollars and shall be paid electronically (via ACH or wire) in immediately available funds on the date due or, if such date is not a Business Day, on the immediately succeeding Business Day to such account as may be designated by Contractor from time to time by Notice to Owner in accordance with Article 30.

6.11 Disputes Regarding Payments. Subject to Contractor’s rights and remedies under Section 19.4(f) and Section 19.5, failure by Owner to pay any amount disputed in good faith until resolution of such dispute in accordance with this Agreement shall not alleviate, diminish, modify nor excuse the performance of, Contractor’s obligations to perform hereunder in any respect, including Contractor’s obligation to meet the Substantial Completion Guaranteed Dates. Contractor’s acceptance of any payment shall not be deemed to constitute a waiver of amounts that are then in dispute. Contractor and Owner shall use their reasonable efforts to resolve all disputed amounts reasonably expeditiously and in accordance with the provisions of Article 32. No payment made hereunder shall be construed to be acceptance or approval of that part of the Work to which such payment relates or to relieve Contractor of any of its obligations hereunder. If a Contractor’s Invoice was properly submitted in accordance with all of the provisions of this Agreement and amounts disputed by Owner in regards to such invoice are later resolved in favor of Contractor, Owner shall pay interest on such disputed amounts due Contractor at the rate set forth in Section 6.7, from the date on which the payment was originally due pursuant to such invoice until payment was received by Contractor.

6.12 Holdbacks.

6.12.1 Owner Holdbacks. Notwithstanding anything to the contrary herein, in addition to the Retainage, upon the occurrence and continuance of any of the following events, Owner, upon Notice to Contractor in accordance with Section 6.12.2, may withhold or retain such portion (including all) of any payment due to Contractor under this Agreement as Owner deems appropriate in Owner’s reasonable discretion to confirm that performance of the Work will be effected in accordance with this Agreement or to protect fully the rights of Owner hereunder:

(iv) Contractor shall have failed to provide appropriate evidence of insurance in conformance with the requirements of this Agreement;

(v) Owner shall have determined that any portion of the Work for which payment has already been made pursuant to a previous Contractor’s Invoice shall contain one or more Errors or Omissions or Defects; provided that the amount so withheld shall not exceed the amount reasonably expected to correct such Error or Omission or Defect; and

(vi) a third-party claim has been filed for which Contractor is obligated to indemnify Owner pursuant to any of the provisions of Article 23 and Contractor has failed to provide the indemnification for such claim in accordance with Section 23.5 within the ten (10) day period provided therein.

6.12.2 Notice of Withholding; Notice of Correction. If, pursuant to Section 6.12.1, Owner intends to withhold any amount from a payment to be made to Contractor, Owner shall, on or before the date that the applicable payment is due to Contractor hereunder, provide a Notice of Withholding to Contractor of any amount that will be so withheld. Such Notice of Withholding delivered pursuant to this Section 6.12.2 shall identify the amount that will be withheld from Contractor, give a reasonably detailed explanation of the reason Owner will withhold such amount, and shall be signed by an authorized agent of Owner. If Contractor receives a Notice of Withholding from Owner pursuant to this Section 6.12.2, Contractor may provide a Notice of Correction to Owner of a condition described in such Notice of Withholding delivered pursuant to this Section 6.12.2. Such Notice of Correction shall be sufficient to identify the scope and manner of the corrective actions to be taken to correct the conditions that are the subject of Section 6.12.1 as identified in such Withholding Notice, and shall be signed by an authorized representative of Contractor.

6.12.3 Payment Following Notice of Correction. If Owner receives a Notice of Correction describing the actions taken to correct any condition described in a Notice of Withholding delivered pursuant to Section 6.12.2, Owner shall pay the amount withheld by Owner for that condition on the date the next payment is due Contractor hereunder, or object to the scope and manner of the correction of the condition, on or before the date the next payment is due to Contractor, in a written statement that sets forth the reason for the objection and otherwise complies with the provisions of Section 6.12.2. If Owner objects to the scope and manner of the corrective actions to be taken with respect to a condition, Owner shall pay to Contractor, along with payment made pursuant to Contractor’s next payment request, the amount withheld for the correction of conditions to which Owner no longer objects.

6.12.4 Limitation on Contractor’s Rights. Notwithstanding the provisions of Sections 19.5 and 32.3, Contractor shall not have any rights of termination or suspension under Section 19.5 as a result of Owner’s good faith exercise or attempted exercise of its rights under this Section 6.12.

6.13 Application of Monies. Contractor shall use the sums paid to it pursuant to this Article 6 for the purpose of performing the Work and designing, furnishing, equipping, testing and commissioning the Project in accordance with the Statement of Work and this Agreement, including payment of the Subcontractors. No provision hereof shall be construed, however, to require Owner or any Financing Entity to see to the proper disposition or application of the monies so paid to Contractor.

6.14 Release of Liability. Acceptance by Contractor of the Final Payment shall constitute a release by Contractor of Owner, their respective Affiliates, the Financing Entities, if any, and every officer, director and employees thereof from all liens (whether statutory or otherwise and including mechanics’ or suppliers’ liens), claims for compensation hereunder with respect to any Work performed or furnished in connection with this Agreement, except claims for which Contractor has delivered a Notice of dispute to Owner.

7.1 Notices to Proceed.

7.1.1 Pre-Contract Letter of Authorization. Owner and Contractor have executed a Pre-Contract Letter Authorization dated April 7, 2006 (the “Pre-Authorization”), whereby Owner authorized Contractor to perform certain engineering, professional and certain other services to be performed in advance of the Parties execution of the Original Agreement. Work performed by Contractor pursuant to the Pre-Authorization was governed by and subject to the terms of the Original Agreement effective as of the execution thereof. Upon execution of the Original Agreement, the Pre-Authorization was terminated and had no further force and effect and the Original Agreement superseded the Pre-Authorization in all respects. Payments made by Owner to Contractor pursuant to the Pre-Authorization shall be credited against the Separated Target Price and Separated Contract Price, as applicable.

7.1.2 Phase One EPC Activities. Upon the execution of the Original Agreement, Contractor was authorized to perform the Work identified in the Phase One EPC Activities set forth in and attached hereto as Exhibit CC, and Contractor shall diligently perform the Work pursuant to such Phase One EPC Activities, assigning to it a priority as necessary for each Unit to achieve Substantial Completion on or before the Substantial Completion Guaranteed Date for such Unit. Notwithstanding Contractor’s authorization to proceed with Phase One EPC Activities, in no event shall Contractor proceed with procurement of any Equipment or Materials during the Open Book Review period costing in the aggregate in excess of One Hundred Thousand Dollars ($100,000) without Owner’s prior written approval, such approval or denial to be provided within five (5) days. The scope of the Work to be completed pursuant to the Phase One EPC Activities may be altered or expanded from time to time pursuant to one or more further written authorizations until Owner has issued a Full Notice to Proceed.

7.1.3 Full Notice to Proceed. On the Full Notice to Proceed Date, Contractor shall commence with the performance of the remainder of the Work in accordance with the Project Schedule and shall thereafter diligently pursue the Work assigning to it a priority as necessary for each Unit to achieve Substantial Completion on or before the Substantial Completion Guaranteed Date for such Unit. If the Full Notice to Proceed Date is later than March 1, 2007, such delay in the Full Notice to Proceed Date shall be an Excusable Event for purposes of this Agreement.

EXECUTION COPY

7.2 Contractor’s Acknowledgment. Contractor expressly agrees that the period of time specified to complete all Work and the timely achievement of the Substantial Completion Guaranteed Dates includes allowance for coordination with Owner, Owner’s Engineer and for all hindrances and delays incident to the Work (other than an Excusable Event or an event of Force Majeure). No claim shall be made by Contractor for hindrances or delays for any cause during the progress of the Work, except as provided under Articles 8 and 16.

7.3 Prosecution of Work. Contractor shall prosecute the Work in accordance with the Project Schedule. Contractor shall cause Substantial Completion of each Unit to occur on or before the applicable Substantial Completion Guaranteed Date.

At a minimum, the updates shall be performed and provided to Owner (in electronic and hard-copy form) on a monthly basis as part of the Monthly Progress Report. Except for the Substantial Completion Guaranteed Dates, which may only be revised or adjusted with Owner’s prior written approval pursuant to a Change In Work Form, Contractor shall revise the Project Schedule from time to time to reflect the current schedule, including Contractor’s then scheduled date of Substantial Completion. Contractor shall employ a project management system capable of providing schedule monitoring and analysis which shall include a comparison of the Project Schedule with the actual progress for each time period with all variances noted. Schedule analysis shall include a determination of the impact of such variance, if material, on the Project Schedule and any action necessary to correct the variance.

7.4.2 Milestone Items. Included within the Project Schedule set forth in Exhibit G are the Milestone Items, including the Project Guaranteed Dates, and the applicable dates of scheduled completion for each such Milestone Item. Except for the Substantial Completion Guaranteed Dates, which shall not be amended, adjusted or revised without Owner’s prior written approval pursuant to a Change In Work Form, Contractor shall revise the Project Schedule from time to time to reflect any changes to the scheduled dates of completion for each Milestone Item. Notwithstanding anything to the contrary in the foregoing, Contractor shall promptly advise Owner of any proposed changes in the scheduled completion of Milestone Items of more than thirty (30) days and the reasons therefor.

7.5 Progress Reporting. From and after the date hereof, Contractor shall prepare a true and correct Monthly Progress Report in the form of Exhibit K and submit it to Owner within ten (10) days after the end of each calendar month.

At Owner’s reasonable request, Contractor shall cause a representative of any Subcontractor to attend such meeting. After commencement of the on-Site Work, Owner, Contractor, and any Major Subcontractor then performing Work on the Site shall each designate a representative to attend meetings as required under this Section 7.6 to review and discuss the progress of the Work. Contractor’s representative at such meetings shall provide a rolling four-week look ahead schedule outlining the Work to be performed at the Site during the four calendar weeks following such meetings.

8. FORCE MAJEURE AND AN EXCUSABLE EVENT

8.1 Force Majeure. No failure or omission to carry out or observe any of the terms, provisions, or conditions of this Agreement shall give rise to any claim by either Party against any other Party hereto, or be deemed to be a breach or default of this Agreement if such failure or omission shall be caused by or arise out of an event of Force Majeure. No obligations of either Party that matured before the occurrence of an event of Force Majeure causing the suspension of performance shall be excused as a result of such occurrence. Notwithstanding anything to the contrary in the foregoing, the obligation to pay money in a timely manner shall not be subject to the Force Majeure provisions.

8.2 Notice. If either Party’s ability to perform its obligations under this Agreement is affected by an event of Force Majeure or an Excusable Event, such Party shall, within ten (10) days after the Project Director in the case of Contractor and the Project Representative in the case of Owner, or their respective designees in the Project Director’s or Project Representative’s absence, becomes aware or reasonably should have become aware of such delay, give Notice to the other Party (a “Delay Notice”) of the occurrence of such event, including as to when such Project Director or Project Representative, as applicable, became aware of the occurrence of such event of Force Majeure. Within ten (10) Business Days after delivery of such Notice, the Party claiming an event of Force Majeure or an Excusable Event shall provide reasonable preliminary information to the other Party of the nature of the event, its anticipated duration and effect upon the performance of such Party’s obligations, and any action being taken to avoid or minimize its effect. The Party claiming an event of Force Majeure or an Excusable Event shall have a continuing obligation to deliver to the other Party additional documentation and analysis supporting its claim regarding an event of Force Majeure or an Excusable Event promptly after such information is available to the Party claiming such event of Force Majeure or an Excusable Event. The burden of proof shall be on the Party claiming to be affected pursuant to this Section 8.2. Within ten (10) Business Days after an event of Force Majeure or an Excusable Event has ended, the Party that was affected by such event of Force Majeure

EXECUTION COPY

or an Excusable Event shall give Notice to the other Party of: (i) the length of time such event of Force Majeure or an Excusable Event was in effect; and (ii) the effect such Party claims such event of Force Majeure or an Excusable Event had on the applicable Substantial Completion Guaranteed Date.

8.3 Scope of Suspension; Duty to Mitigate. The suspension of or impact on performance due to an event of Force Majeure or an Excusable Event shall be of no greater scope and no longer duration than is required by such event. The excused Party shall use its reasonable efforts:

(a) to mitigate the duration of, and costs arising from, any suspension or delay in, or other impact to the performance of its obligations under this Agreement;

(b) to continue to perform its obligations hereunder; and

When the affected Party is able to resume performance of its obligation under this Agreement, such affected Party shall give the other Party Notice to that effect.

8.4 Removal of Force Majeure. If, within a reasonable time after the occurrence of an event of Force Majeure that has caused Contractor to suspend or delay performance of the Work, Owner has identified and recommended to Contractor commercially reasonable action to be undertaken, and Contractor has failed within five (5) days after receipt of Notice from Owner thereof to take such action as Contractor could lawfully and reasonably initiate to remove or relieve either the event which caused such an event of Force Majeure or its direct or indirect effects, Owner may, in its sole discretion and after Notice to Contractor, initiate such reasonable measures as will be designed to remove or relieve such an event of Force Majeure or its direct or indirect effects and thereafter require Contractor to resume full or partial performance of the Work.

8.5 Responsibility of Contractor. Subject to the limitations on liability contained in this Agreement, damages or injuries to persons or properties resulting from an event of Force Majeure during the performance of the obligations provided for in this Agreement shall not relieve Contractor of any responsibility it may have pursuant to the terms of this Agreement to bear the cost of the damage or injuries as provided herein.

8.6 Contractor’s Remedies.

8.6.1 Force Majeure. As Contractor’s only remedy for the occurrence of an event of Force Majeure, and provided Contractor has otherwise complied with the provisions of Sections 8.2 and 8.3, if an event of Force Majeure occurs: (i) the applicable Substantial Completion Guaranteed Dates shall be extended and the Project Schedule, Milestone Items and any related modifications to the Work shall be correspondingly adjusted by the period of time, if any, that Contractor is actually and demonstrably delayed in the performance of the Work as a result of the impact of such an event of Force Majeure, less any extensions of such event of Force Majeure that occur due to Contractor’s failure to take action as requested by Owner pursuant to Section 8.4, and (ii) and the impact of such event of Force Majeure delays the Work for five (5) or more consecutive days with respect to any one Force Majeure event, or the impact of multiple Force Majeure events delays the Work for greater than fifteen (15) days in the

EXECUTION COPY

aggregate, and Contractor’s costs actually and demonstrably increase despite Contractor’s commercially reasonable efforts to mitigate any such increases, the Separated Contract Price shall be adjusted.

8.6.2 Excusable Event. As Contractor’s only remedy for the occurrence of an Excusable Event, and provided that Contractor has otherwise complied with the provisions of Sections 8.2 and 8.3, if an Excusable Event occurs: (i) the applicable Substantial Completion Guaranteed Dates shall be extended and the Project Schedule, Milestone Items, and any related modifications to the Work shall be correspondingly adjusted by the period of time, if any, that Contractor is actually and demonstrably delayed in the performance of the Work as a result of the impact of such an Excusable Event, less any extensions of such Excusable Event that occur due to Contractor’s failure to take action as requested by Owner pursuant to Section 8.4, and (ii) if Contractor’s costs actually and demonstrably increase despite Contractor’s commercially reasonable efforts to mitigate any such increases, the Separated Contract Price shall be adjusted. Notwithstanding anything to the contrary in the foregoing or in this Agreement, upon the occurrence of an Excusable Event as described in subsection (f) of the definition of Excusable Event, Contractor’s only remedy for such Excusable Event shall be an adjustment of the Net Unit Capacity Guarantee and Net Unit Heat Rate Guarantee for Unit 1 or Unit 2, as the case may be, to the extent necessary to reflect the total volume discharge limitations in the current Discharge Permit, and Contractor shall not be entitled to a Change In Work adjusting the Substantial Completion Guaranteed Date or Separated Contract Price in connection with such Excusable Event. Contractor and Owner shall document the adjusted Net Unit Capacity Guarantees and Net Unit Heat Rate Guarantees in writing, which shall be signed by duly authorized representatives of both such Parties.

8.6.3 Changes In Work. Upon the occurrence of an event of Force Majeure or an Excusable Event to which Contractor is entitled to a change in the applicable Substantial Completion Guaranteed Dates, Separated Contract Price or modifications to the Work pursuant to this Section 8.6, Contractor and Owner shall prepare a Change In Work form in accordance with Article 16.

8.7 Owner’s Right to Terminate. If an event of Force Majeure has occurred and continues for more than six (6) months, Owner may terminate this Agreement by notice to Contractor. Upon such termination, Contractor shall be entitled to receive the payments as set forth in Section 20.1.1.

Contractor shall notify Owner of any additional subcontractors, suppliers or vendors with whom Contractor anticipates subcontracting and any portion of the Work to be performed by such proposed subcontractor, supplier or vendor, for Owner’s review, and approval with respect to Major Subcontractors; provided that after completion of the Open Book Review, Exhibit O shall not be amended with respect to any Major Subcontractor previously approved by Owner without Owner’s written approval, and

EXECUTION COPY

Contractor shall notify Owner of any changes to Exhibit O with respect to any additional subcontractors, suppliers or vendors with whom Contractor anticipates subcontracting and any portion of the Work to be performed by such proposed subcontractor, supplier or vendor, for Owner’s review, and approval with respect only to direct (i.e., first tier) Major Subcontractors. Contractor shall update and amend Exhibit O by Notice to Owner from time to time as necessary to reflect additions or changes thereto. Contractor shall use commercially reasonable efforts to ensure that each Subcontractor is licensed or qualified to do business and is in good standing under the laws of the jurisdiction where the Work is to be performed, including the State of Texas or otherwise not to contract with such Subcontractor for any portion of the Work. Contractor acknowledges and agrees that Owner’s selection of Contractor to perform the Work was due in part to Contractor’s commitment to, and Contractor hereby agrees to, directly hire and self perform the majority of mechanical and electrical construction portions of the Work.

9.2 Agency Subcontracts Prior to Assignment. Prior to assignment of the Agency Subcontracts to Contractor pursuant to Section 4.2.7(b), Contractor shall act as Owner’s agent to prepare and execute the Agency Subcontracts (including an amendment to the STG Upgrade Contract), subject to Owner’s approval of such Agency Subcontracts prior to execution thereof. Owner and Contractor shall cooperate to negotiate and finalize the Agency Subcontracts, including amending the STG Upgrade Contracts to the extent mutually agreed upon by Owner and Contractor, as required and by such dates so as to avoid delays to the Work. In the event the negotiation and execution of any such Agency Subcontracts is delayed and the Project Schedule is adversely impacted (provided that Contractor is not acting in a commercially unreasonable manner), Contractor shall be entitled to a Change In Work to the extent such delay actually and demonstrably impacts the Substantial Completion Guaranteed Date for the applicable Unit or the Separated Contract Price. With respect to the STG Upgrade Contract, Owner shall, or shall cause TXU Energy Company LLC to appoint Contractor as Owner’s or TXU Energy Company LLC’s agent, respectively. While acting as Owner’s agent, Contractor shall administer and enforce the Agency Subcontracts as necessary to accomplish the Work.

9.3 Use of Contractor’s Affiliates. Notwithstanding the above, Contractor may have portions of the Work performed by certain of its Affiliates or their employees, in which event Contractor shall be responsible for such Work, Owner will look solely to Contractor as if the Work were performed by Contractor, and such Affiliates shall comply with the obligations of Contractor hereunder to the extent applicable to the Work they perform.

9.4 Assignment. No subcontract or purchase order shall bind or purport to bind Owner, but each subcontract and purchase order entered into by Contractor with respect to the Work where the applicable subcontract price or purchase order value exceeds One Hundred Thousand Dollars ($100,000) shall provide for assignment of such subcontract as set forth in Section 9.6.

9.5 Information and Access. Contractor shall furnish such information and access relative to the identity of and scope of services or supply of its Subcontractors as Owner may reasonably request; provided that nothing herein shall be deemed to limit Owner’s rights to information and access to Subcontractors during the Open Book Review; provided, further, that Owner shall be entitled to such information as reasonably necessary to enable Owner to verify compliance with the provisions of Section 9.6.

EXECUTION COPY

9.6 Terms in Subcontracts. All subcontracts between Contractor and its direct (i.e., first tier) Subcontractors, as well as Subcontractors which have contract values in excess of $1,000,000 or provide critical parts or components, shall be consistent with the requirements of this Agreement, insofar as applicable. All Work performed for Contractor by such direct (i.e., first tier) Subcontractors shall be pursuant to an appropriate written agreement between Contractor and the Subcontractor that contains provisions that:

(a) reasonably preserve and protect all the rights of Owner under this Agreement and to the Work to be performed under the subcontract, so that the subcontracting thereof will not prejudice such rights;

(b) require that such Work be performed in accordance with the applicable requirements of this Agreement;

(c) require such Subcontractor to make available a representative with whom Owner or the Financing Entities, if any, may, subject to Contractor’s coordination and participation, discuss questions regarding the Work being performed by the Subcontractor;

(d) with respect only to Subcontractors that are supplying goods for which functional spare parts are customarily provided, require such Subcontractors which have contract values in excess of $250,000 or provide critical parts or components to notify Contractor and Owner in the event such Subcontractor decides to discontinue supplying any functional spare parts at any time within five (5) years after completion of such Subcontractor’s portion of the Work, so that Owner may seek to order any quantity of any of such parts at the prices prevailing at the time of such order, prior to such discontinuance of supply;

(e) require such Subcontractor to participate in the OCIP if eligible and to provide and maintain adequate insurance consistent with its obligations related to this Agreement (as adjusted by Contractor and Owner pursuant to Section 21.2.3);

(g) require such Subcontractor to enter into a new contract directly with Owner on substantially the same terms and conditions as such subcontract in the event that any trustee in bankruptcy for Contractor rejects the subcontract, or the Subcontractor terminates such subcontract as a result of the bankruptcy of Contractor;

(h) allow assignment, including any performance assurance provided by such Subcontractor, of such agreement to Owner, to another contractor providing engineering, procurement and construction services to Owner that replaces the Contractor as designated by Owner, or at Owner’s request, to the Financing Entities, if any, upon the termination or expiration of this Agreement in accordance with its terms, upon notice to Subcontractor but not subject to Subcontractor’s consent provided that any such assignee (except for collateral assigns) shall have sufficient creditworthiness to meet its payment obligations to Subcontractor and provided further that any such assignee shall not be a direct competitor of such Subcontractor;

EXECUTION COPY

(i) require such Subcontractor to remove any employee or independent contractor of such Subcontractor used in the Work at the Site or in such Subcontractor’s warranty obligations within ten (10) days after receiving notice from Contractor that Owner requires removal of such employee or independent contractor;

(j) if commercially obtainable, provide that if this Agreement is terminated before Final Completion, such Subcontractor shall not be entitled to any profit or fee to the extent any portion of its Work has not been completed;

(l) require such Subcontractor to deliver to Owner any “stop-work” notice or termination notice delivered to Contractor pursuant to Applicable Law.

Notwithstanding the foregoing, Owner acknowledges and agrees that the STG Upgrade Contract was initially entered into by an Affiliate of Owner and may not contain all of the provisions set forth in the foregoing. Contractor shall use commercially reasonable efforts to incorporate the missing provisions into the STG Upgrade Contract.

In addition to the provisions of this Section 9.6, this Agreement contains numerous references expressly requiring Contractor to cause its Subcontractors to perform certain actions or adhere to certain requirements (such additional required actions or requirements, “Flowdowns”). Contractor may exercise its reasonable discretion, in consultation with Owner, in negotiating the terms of its subcontracts with its Subcontractors that result in either excluding the use of certain Flowdowns that are not applicable to a particular Subcontractor based on the scope and nature of the subcontracted work or scope of supply, or modifying the terms of such Flowdowns in order to effect a reasonable commercial agreement with such Subcontractors, and Contractor’s exclusion or modification of such Flowdowns in such subcontracts shall not be considered a breach of this Agreement; provided that notwithstanding the foregoing, Contractor shall require each Subcontractor, insofar as applicable, to take such actions or adhere to such requirements as provided in Section 3.13, Section 4.1.8, Section 5.7.2, Section 10.4 (with respect to Subcontractors that perform Work on the Site), Section 21.3 and Article 28 (with respect to Subcontractors that perform Work on the Site). Contractor acknowledges and agrees that the provisions of this paragraph shall not constitute a waiver or modification by Owner of any of Contractor’s other obligations hereunder.

9.7 Minority and Women-Owned Businesses. Contractor acknowledges that Owner and its Affiliates are committed to the development, utilization and inclusion of certified women and minority owned businesses, as well as small businesses, businesses owned by veterans and service-disabled veterans, and businesses located in historically underutilized business zones, in Owner’s and its Affiliates’ sourcing and procurement processes. Contractor shall provide Owner with reasonably satisfactory evidence that Contractor considered such businesses for inclusion in Contractor’s Subcontractors and Suppliers. Contractor acknowledges that Contractor’s Invoices shall include information regarding the amount of such Invoices reflecting utilization of and amounts spent with such businesses by Contractor, and to the extent such information can be

EXECUTION COPY

obtained from the Subcontractors using commercially reasonable efforts, by the Subcontractors, and Contractor agrees to provide such additional information, and to use commercially reasonable efforts to cause the Subcontractors to provide such information, regarding utilization of such businesses as Owner reasonably requests. Contractor shall further provide Owner with reasonably satisfactory evidence that its Subcontractors and Suppliers were selected in a non-discriminatory manner and, at least in part, on the basis of their qualifications and capabilities.

10. LABOR RELATIONS

10.1 General Management of Employees. Subject to Section 10.6, and notwithstanding the provisions of Section 10.3, Contractor shall preserve its rights to exercise and shall exercise its management rights in performing the Work. Such management rights shall include the rights to hire, discharge, promote, and transfer employees; to select and remove foremen or other persons at other levels of supervision; to establish and enforce reasonable standards of production; to introduce, to the extent feasible, labor saving Equipment and Materials; to determine the number of craftsmen necessary to perform a task, job, or project; and to establish, maintain, and enforce rules and regulations conducive to efficient and productive operations.

Contractor shall submit its proposed program regarding its proposed worker training program to Owner for review within sixty (60) days after the date hereof. Contractor shall implement and follow the approved program during the performance of the Work.

10.3 Labor Disputes. Contractor shall use reasonable efforts to adopt policies and practices designed to avoid work stoppages, slowdowns, disputes and strikes, and to minimize the risk of labor-related delays or disruption of the progress of the Work. Contractor shall promptly take any and all reasonable steps that may be available in connection with the resolution of violations of collective bargaining agreements or labor jurisdictional disputes, including the filing of appropriate processes with any court or administrative agency having jurisdiction to settle, enjoin, or award damages resulting from violations of collective bargaining agreements or labor jurisdictional disputes. Contractor shall advise Owner promptly, in writing, of any actual or threatened labor dispute of which Contractor has knowledge that might materially affect the performance of the Work by Contractor or by any of its Subcontractors. Notwithstanding the foregoing, the settlement of strikes, walkouts, lockouts or other labor disputes shall be at the discretion of the Party having the difficulty.

10.4 Personnel Documents. Contractor shall ensure that at the time of hiring, all its personnel and personnel of any Subcontractors performing the Work are in possession of all such documents (including visas, driver’s licenses and work permits) as may be required by any and all Applicable Laws.

EXECUTION COPY

Any replacement of the Key Personnel shall be subject to the prior written consent of Owner, which consent shall not be unreasonably withheld. If Owner fails to respond to a request for consent within five (5) Business Days after Contractor’s request, Owner shall be deemed to have consented to the proposed individual.

10.6 Replacement of Employees and Other Persons at Owner’s Request. Within ten (10) days after receiving a written request by Owner identifying the lawful reason for such request, Contractor shall remove from the Project, the Site and from any performance of the Work, and cause any Subcontractor to remove from the Project, the Site and from any performance of the Work, as soon as reasonably practicable, any Person performing the Work (including any of the Key Personnel other than the Project Director and his direct reports) whom Owner reasonably demonstrates to be creating a material safety hazard or risk of either: (a) non-achievement of any of the Substantial Completion Guaranteed Dates for either Unit; or (b) material non-performance by Contractor in accordance with this Agreement. Contractor acknowledges that Owner desires to maintain a positive perception of the Project and a good working relationship with the surrounding communities and that actions of Contractor’s employees or agents, including the Subcontractor’s employees may affect the local communities. Accordingly, Contractor shall also remove, and cause its Subcontractors to remove, any employee, agent or other Person engaged in the performance of the Work for Contractor or such Subcontractor, as the case may be, whose off-Site conduct Owner reasonably demonstrates is harming or having a negative effect on the perception of the Project or Owner’s relationship with the surrounding community. In the event Contractor disagrees that any such Person should be removed pursuant to this Section 10.6, Owner and Contractor shall submit such disagreement to their executive management pursuant to Section 32.1.

To facilitate such observations and inspections, Contractor shall maintain at the Site a complete set of all Submittals, Supplier reports, and current Project Schedule.

11.3 Contractor Submittals Table. Within fifteen (15) Business Days after the date hereof, Contractor shall provide a Notice to Owner attaching an initial proposed Contractor Submittals Table identifying all Contractor Deliverables to be delivered to Owner for review and comment in accordance with Exhibit A-1–Section 01330, the deadline for delivery thereof, and reference to this Agreement or Exhibit where such submittal is required. Owner shall have the right to review and approve such Contractor Submittals Table. Contractor shall update such Contractor Submittals Table from time to time throughout the Open Book Review process, until finalized.

11.4 Owner Review of Documents. Contractor shall submit to Owner for review, and approval or acceptance as provided herein, hard (printed) copies and soft copies (in a format agreed to by Owner) of all Contractor Deliverables in accordance with the requirements of Exhibit A-1-Section 01330 and the Contractor Submittals Table.

11.5 Remedy of Flaws. If Owner identifies any errors or omissions with respect to any Contractor Deliverable submitted for review, Contractor shall incorporate changes into such Contractor Deliverable addressing and remedying the errors and omissions and resubmit the same to Owner, and such incorporation of changes to address Owner’s comments shall not be considered a Change In Work and shall not affect the Substantial Completion Guaranteed Dates.

12. SITE CONDITIONS

12.1 Site Conditions. Owner has advised Contractor of any Site Conditions known to Owner; provided that Contractor acknowledges that Owner has not had and will not have any duty to investigate or review any information regarding any Site Conditions.

Contractor shall keep the Project Representative continuously apprised of the specified schedule, and changes therein, for the commencement and performance of Acceptance Tests, and shall give the Project Representative at least three (3) Business Days prior Notice of the re-performance of any Acceptance Test; provided that such period of prior notice may be reduced if the Project Representative is at the

EXECUTION COPY

Site and receives reasonable prior notice of re-performance of any Acceptance Test. An Acceptance Test conducted without the required Notice shall not be valid for the purposes of this Agreement.

13.5 Testing. Contractor shall achieve Mechanical Completion, start up each Unit and shall satisfy all of its other obligations under this Agreement with respect to each Unit to complete the Unit in accordance with the terms of this Agreement and properly adjust and test components as Contractor determines is necessary prior to conducting the Acceptance Tests.

Contractor must submit a preliminary test report for each Acceptance Test within forty eight (48) hours after the completion of such Acceptance Test providing a summary of each Acceptance Test and raw data taken during such Acceptance Test, and a final test report within thirty (30) days thereafter. Contractor shall include sufficient results of testing in the preliminary test reports to allow Owner to reasonably determine that the final test results are expected to be satisfactory for the purposes of obtaining Substantial Completion.

13.6 Non-Conforming Work. At any time during and promptly after completion (whether or not successful) of the Acceptance Tests under Section 13.3 (or any re-performance of any Acceptance Test under Section 13.5, Section 13.9 or pursuant to any Remedial Plan), Owner shall advise Contractor and Contractor shall advise Owner in writing of any Error or Omission or Defect that was discovered during an Acceptance Test.

Any dispute regarding the existence or correction of any such Error or Omission or Defect shall be resolved pursuant to Article 32.

13.7 Certificate of Completion of Testing. Upon the Successful Run of an Acceptance Test as demonstrated by a test report delivered to Owner by Contractor, Owner shall issue a Notice that such test has been Successfully Run.

13.8 Revenues. Any revenues generated by the Project during start up and commissioning, or the performance of any Acceptance Test or any other testing otherwise performed shall be paid to and for the benefit of Owner.

(b) a certificate of completion of such Acceptance Test has been issued pursuant to Section 13.7;

EXECUTION COPY

(d) such modification could have had a material effect on the outcome of such Acceptance Test, if it had been made before the completion of such Acceptance Test, then such Acceptance Test shall be re-run, as a condition to achieving Substantial Completion for such Unit.

14. SUBSTANTIAL COMPLETION AND FINAL COMPLETION

14.1 Punchlists.

14.1.1 Creation of Punchlists. When Contractor believes that a system of a Unit is ready for commissioning and start up, Contractor shall prepare and submit to Owner a punchlist of Work remaining to be completed with respect to such system in accordance with Exhibit S. Any Non-Critical Deficiencies with respect to each system of a Unit will be included on a list of items of Work that may be completed after the Substantial Completion Date, which list shall include, for each Non-Critical Deficiency, a proposed schedule and estimated cost for the completion or repair of such Non-Critical Deficiency (the “Proposed Punchlist”). Owner and Contractor shall determine whether the Proposed Punchlist for a Unit includes all Non-Critical Deficiencies for such Unit, whether the Proposed Punchlist includes only Non-Critical Deficiencies and whether the Unit is complete except for those items described in the Proposed Punchlist. If Owner’s inspection discloses any Non-Critical Deficiency that has been excluded from the Proposed Punchlist, any item described on the Proposed Punchlist that is not a Non-Critical Deficiency, any item of Work included in the system that is incomplete or not in accordance with this Agreement (other than Non-Critical Deficiencies described on the Proposed Punchlist), Owner shall deliver Notice thereof to Contractor. If Owner does not deliver such a Notice to Contractor within a reasonable period of time not to exceed ten (10) days, the Proposed Punchlist shall be deemed acceptable to Owner. If Owner delivers such a Notice to Contractor, Contractor shall complete any items of Work other than Non-Critical Deficiencies, revise the Proposed Punchlist to include all Non-Critical Deficiencies identified by Owner (whether or not such items are disputed by Contractor) and resubmit the revised Proposed Punchlist to Owner for review. Until the Substantial Completion Date, Owner may re-inspect the Unit and the foregoing process shall continue on an iterative basis until Owner has approved the Proposed Punchlist for such Unit. If the Proposed Punchlists are prepared or separated by systems of a Unit, the aggregate of all Proposed Punchlists for a Unit that are acceptable or deemed acceptable to Owner shall sometimes be referred to as the “Punchlist.” If the Punchlist for a Unit is not finalized by the Substantial Completion Date for such Unit, the Proposed Punchlist as modified by Owner shall be deemed the Punchlist for such Unit for all purposes hereunder until the Parties resolve such dispute and otherwise finalize the Punchlist. Contractor shall note on such Proposed Punchlist the items under dispute. Prior to the Substantial Completion Date of each Unit, any Non-Critical Deficiencies discovered by Contractor or identified by Owner after the initial inspection of each system of such Unit by Owner and Contractor or during the testing of the Unit shall be added to the Punchlist.

14.1.2 Completion of Punchlists. Contractor shall proceed promptly to complete and correct all items on the Punchlist for a Unit in accordance with the schedule to complete such items to be agreed upon by the Parties as soon as practical after Substantial Completion of such Unit. Contractor shall complete all items on the Punchlist promptly after Owner receives such Punchlist and in any event in accordance with the schedule set forth in such Punchlist. On a

weekly basis after Substantial Completion of each Unit, Contractor shall revise and update the Punchlist for such Unit to include the date(s) that items listed on such Punchlist are completed by Contractor and accepted by Owner. Notwithstanding any of the foregoing, the items listed on such Punchlist shall not be considered complete until Owner shall have inspected such Non-Critical Deficiencies and acknowledged, by notation on the updated Punchlists, that such item of Work is complete. If Owner does not so inspect and deliver such notations on the updated Punchlists to Contractor within a reasonable period of time, and Contractor has actually completed and corrected all items on the Punchlist, the Punchlist shall be deemed completed on the date that is twenty (20) days after Contractor submits the updated Punchlist to Owner after having completed the last Punchlist item.

14.1.3 Owner’s Punchlist Option. At any time after the one hundred eightieth (180^th) day after the Substantial Completion Date of a Unit, Owner may elect, by Notice to Contractor to deduct and keep from the Retainage or draw from the Letter of Credit an amount equal to one hundred fifty percent (150%) of the estimated cost to complete the uncompleted items on the Punchlist for such Unit in lieu of requiring Contractor to complete such items. Following Contractor’s receipt of such Notice, Owner shall determine, which items on such Punchlist have not been completed and Contractor shall prepare an estimate of the cost to complete such items. Owner shall then be permitted to deduct and keep from the Retainage, or draw from the Letter of Credit, such amount in satisfaction of Contractor’s obligation to complete such items.

14.2 Substantial Completion. The following are conditions precedent to Substantial Completion for each Unit:

(a) the results of the applicable Acceptance Test of such Unit reflect achievement of the Minimum Performance Criteria;

(b) subject to Section 14.3, Contractor shall have paid all undisputed Delay Liquidated Damages due pursuant to Section 15.1 (provided that all amounts of disputed Delay Liquidated Damages that are ultimately determined to be due and owing shall accrue interest from the date such amounts are determined to have been owed);

(c) Owner has received all Contractor Deliverables in accordance with the Contractor Submittals Table, including all Required Manuals identified therein for delivery prior to Substantial Completion;

(d) pursuant to Section 3.19.1, training of Operating Personnel is complete;

(e) the Punchlist for such Unit shall be in final form or be deemed to be in final form as provided in Section 14.1.1;

(f) all Work related to such Unit other than record drawings and items of Non-Critical Deficiency listed on the Punchlist shall have been completed without any Errors or Omissions or Defects;

(g) Contractor shall have licensed or granted, in accordance with this Agreement, all Intellectual Property Rights necessary for such Unit to be operated by Owner

EXECUTION COPY

without violating any of Contractor’s, any Subcontractor’s or any third party’s rights to such Intellectual Property Rights;

(h) Contractor shall have delivered all applicable Conditional Waivers and Releases Upon Milestone or Progress Payment from Contractor, and, as applicable, Conditional Waivers and Releases Upon Milestone or Progress Payment, Conditional Waivers and Releases Upon Final Payment and Unconditional Waivers and Releases Upon Final Payment from each Major Subcontractor, or shall have delivered security in lieu thereof, as required to be delivered pursuant to Section 6.4; and

(i) all operational spare parts used by Contractor prior to the Substantial Completion Date that are to be replaced or reconditioned by Contractor pursuant to Section 3.20.3 have been delivered or purchased for delivery to Owner and all special tools have been turned over to Owner.

14.3 Notice of Substantial Completion. When Contractor believes that it has satisfied the provisions of Section 14.2 for a Unit, Contractor shall deliver to Owner a Notice of Substantial Completion, including a certification of all applicable Performance Test results. The Substantial Completion Date for such Unit shall be the day after the date on which the last of the conditions of Section 14.2 was satisfied for such Unit or, in the sole discretion of Owner, waived. Owner shall, within five (5) days after receipt of a Notice of Substantial Completion, issue an Owner’s Certificate of Substantial Completion for such Unit dated to reflect the Substantial Completion Date for such Unit, or if Owner rejects Contractor’s Notice of Substantial Completion, respond in writing giving its reasons for such rejection and Contractor shall take the appropriate corrective action. If Owner fails to respond to a Notice of Substantial Completion within such five (5) day period, Substantial Completion shall be deemed to have occurred as of the date of Contractor’s Notice of Substantial Completion. Upon completion of such corrective action, Contractor shall provide a new Notice of Substantial Completion for such Unit to Owner for approval. This process shall be repeated on an iterative basis until Owner accepts the Notice of Substantial Completion for such Unit and issues an Owner’s Certificate of Substantial Completion. Notwithstanding the provisions of Section 14.2(a), in order to properly determine the amount of Delay Liquidated Damages due and owing (if any), and to arrange a wire transfer or other means of payment, Contractor shall be deemed to have satisfied the provisions of Section 14.2(a) with respect to the payment of undisputed Delay Liquidated Damages due and owing if Contractor pays such amount to Owner by the date which is five (5) days after the date on which the last of the conditions of Section 14.2 was satisfied (other than clause (a) thereof) or, in the sole discretion of Owner, waived. Notwithstanding the foregoing, if Contractor does not pay all such undisputed Delay Liquidated Damages by such date to Owner, then Substantial Completion for such Unit shall not be deemed to have occurred hereunder until the date on which Contractor shall have paid all such undisputed amounts (which undisputed amounts shall include, for purposes of clarification, Delay Liquidated Damages in the amounts required under Section 15.1 for the five (5) day period noted above and for each day thereafter up to and including the day on which Contractor actually makes such payment to Owner).

14.4 Final Completion. Final Completion of a Unit shall be deemed to have occurred only if all of the following have occurred:

EXECUTION COPY

(a) Substantial Completion of such Unit has been achieved;

(b) intentionally omitted;

(c) Owner has received copies of all Contractor Acquired Permits and associated approvals required to be obtained by Contractor pursuant to Section 3.9;

(d) intentionally omitted;

(e) Contractor shall have completed all items on the Punchlist for such Unit unless Owner shall have relieved Contractor of its obligation to do so under Section 14.1.3;

(f) Contractor shall have completed all of the Work related to such Unit;

(g) Owner shall have received all Submittals, copies of final record drawings, electronically prepared computer drawing file(s) as prepared by Contractor on a software program acceptable to Owner as required by Exhibit A-1–Section 01330, calculations, test data, performance data, Equipment and Materials descriptions (other than the Owner Furnished Equipment), Required Manuals, training aids (which, in the case of Unit 1, shall include the common facilities to Units 1 and 2);

(h) Contractor and each Subcontractor enrolled in the OCIP shall have complied with the audit and closeout report requirements of the OCIP in accordance with Section 21.1;

(i) with regards to Final Completion of ▇▇▇▇ ▇, all Contractor’s and Subcontractors’ personnel shall have left the Site, and all surplus materials, waste materials, rubbish, and construction facilities other than those to which Owner holds title shall have been removed from the Site as required by Exhibit A-1–Section 01530, and any permanent facilities used by Contractor and the Site shall have been restored to the same condition that such permanent facilities and the Site were in on the Full Notice to Proceed Date, ordinary wear and tear excepted. All cleanup and disposal shall be conducted in accordance with all Applicable Laws and Applicable Permits;

(j) Contractor shall have assigned to Owner, or provided Owner, with all warranties or guarantees with respect to such Unit that Contractor received from Subcontractors to the extent Contractor is obligated to do so pursuant to Article 17;

(k) Contractor has delivered an Unconditional Waiver and Release Upon Final Payment of Contractor and an Unconditional Waiver and Release Upon Final Payment of Subcontractor from such Major Subcontractors, or the bonds, in accordance with Section 6.9, with respect to such Unit, and has delivered such other documents and certificates with respect to such Unit as Owner has reasonably requested to ensure compliance with all Applicable Laws for which Owner could be liable; and

(l) Contractor shall have paid to Owner all Delay Liquidated Damages and Performance Liquidated Damages (including any disputed amounts not previously paid) due and owing pursuant to the terms of Sections 15.1 and 15.3 with respect to such Unit.

EXECUTION COPY

14.5 Notice of Final Completion. Contractor shall deliver to Owner a Notice of Final Completion stating that Contractor believes it has satisfied the provisions of Section 14.4 with respect to such Unit. Within ten (10) business days after receipt of the Notice of Final Completion, Owner shall issue an Owner’s Certificate of Final Completion to Contractor evidencing that, to the best of Owner’s knowledge, all of Contractor’s construction obligations under this Agreement with respect to such Unit have been satisfied and Final Completion of such Unit has been achieved, or if Owner rejects Contractor’s Notice of Final Completion, respond in writing giving Owner’s reasons for such rejection and Contractor shall promptly take the appropriate corrective action. Upon completion of such corrective action, Contractor shall resubmit a Notice of Final Completion for such Unit to Owner for approval. This process shall be repeated until Owner accepts Contractor’s Notice of Final Completion and issues an Owner’s Certificate of Final Completion. Owner shall use commercially reasonable efforts to advise Contractor within ten (10) business days after Contractor has delivered a Notice of Final Completion why a Unit has not achieved Final Completion, and if Owner has not responded to such Notice of within twenty (20) business days after Contractor delivers such Notice of Final Completion, Final Completion of such Unit shall be deemed to have occurred.

14.6 Contractor’s Access After Substantial Completion and Final Completion. Following Substantial Completion of a Unit, Owner shall provide Contractor with reasonable and timely access to such Unit to complete all items on the Punchlist for such Unit and to satisfy the other requirements with respect to that Unit for Final Completion. The Parties expect that Contractor shall accomplish any necessary modification, repairs or additional work with minimal interference with commercial operation of the Project and that reductions in and shut-downs of the Project’s operations will be required only when necessary, taking into consideration the length of the proposed reduction or shut-down, and Owner’s obligations and liabilities to customers or others. Notwithstanding the foregoing, should a reduction in or shut-down of the Project’s operations be required to complete any items on the Punchlists, then such reduction or shut-down shall be scheduled solely at the discretion of Owner and Contractor shall complete such Work during such Owner scheduled reduction or shut-down. Contractor acknowledges that Owner may schedule such reduction or shut-down at any time including off-peak hours, nights, weekends and holidays.

15. LIQUIDATED DAMAGES

15.1 Liquidated Damages for Delay in the Substantial Completion Dates. Contractor understands that if the Substantial Completion Date for each Unit does not occur on or before the Substantial Completion Guaranteed Date for such Unit, Owner will suffer substantial damages, including the loss of operating revenue, additional interest and financing charges on funds obtained by Owner to finance the Work, reduction of return on Owner’s equity investment in the Project, and other operating and construction costs and charges. Therefore, Contractor agrees that if Substantial Completion for a Unit is not achieved by the Substantial Completion Guaranteed Date for such Unit, Contractor shall pay liquidated damages (“Delay Liquidated Damages”) to Owner in the amount of (a) beginning on the thirty-first (31^st) day of such delay, and for each day (or portion thereof) of delay thereafter through the sixtieth (60^th) day of such

EXECUTION COPY

delay, *** Dollars ($***) per day for each day (or portion thereof) of such delay; (b) beginning on the sixty-first (61^st) day of such delay and for each day (or portion thereof) of delay thereafter through the ninetieth (90^th) day of such delay, *** ($***), per day for each day (or portion thereof) of such delay; and (c) beginning on the ninety-first (91^st) day of such delay and for each day (or portion thereof) of delay thereafter, *** Dollars ($***), per day for each day (or portion thereof) of such delay. Any amount Contractor is obligated to pay to Owner under this Section 15.1 shall be subject to the limitations set forth in Section 31.2.2 and shall be due and payable ten (10) Business Days after receipt of a Notice from Owner requesting such payment.

15.2 Intentionally Omitted.

15.3 Liquidated Damages for Failure to Satisfy Net Unit Capacity and Net Unit Heat Rate Guarantees. Contractor understands that if the Units do not each achieve the Net Unit Capacity Guarantee and the Net Unit Heat Rate Guarantee, Owner will suffer substantial damages, including the loss of operating revenue, reduction of return on Owner’s equity investment in the Project, and other operating and construction costs and charges. Therefore, Contractor agrees that if a Unit does not achieve the Net Unit Capacity Guarantee, as calculated in accordance with Exhibit I-2, Contractor shall pay liquidated damages to Owner in the amount of *** Dollars ($***) per kilowatt for each kilowatt by which such Unit fails to satisfy the Net Unit Capacity Guarantee. Contractor further agrees that if a Unit does not achieve the Net Unit Heat Rate Guarantee, as calculated in accordance with Exhibit I-2, Contractor shall pay liquidated damages to Owner in the amount of *** Dollars ($***) per Btu/kilowatt hour for each Btu/kilowatt hour by which such Unit exceeds the Net Unit Heat Rate Guarantee. Any amount Contractor is obligated to pay to Owner under this Section 15.3 shall be subject to the limitations set forth in Section 31.2.2 and shall be due and payable as determined in accordance with Sections 15.4 and 15.5.

15.4 Actions During the Cure Period.

15.4.1 If Minimum Performance Criteria are Satisfied. If based on the results from the most recent Performance Tests for a Unit, such Unit shall have satisfied the Minimum Performance Criteria but not the Net Unit Capacity Guarantee or the Net Unit Heat Rate Guarantee, and each Acceptance Test for such Unit has been Successfully Run, Contractor, at its option, shall elect to either:

(a) pay Owner the Performance Liquidated Damages as determined pursuant to Section 15.3 based on the results of the most recently completed Performance Test of such Unit, in which case Owner shall calculate such amount and deliver a Notice For Payment of Performance Liquidated Damages for such Unit to Contractor, and after payment of such Performance Liquidated Damages, Contractor shall have no further obligation to try to achieve the Net Unit Capacity Guarantee and Net Unit Heat Rate Guarantee, as applicable, with respect

*** CONFIDENTIAL MATERIAL REDACTED AND FILED SEPARATELY WITH THE COMMISSION.

EXECUTION COPY

to such Unit; or

(b) continue to attempt to satisfy the applicable Performance Guarantees for such Unit, until the earlier of one hundred eighty (180) days after the Substantial Completion Guaranteed Date for such Unit or until the expiration of a previously implemented Remedial Plan and Contractor’s election to pay Owner the Performance Liquidated Damages and achieve Substantial Completion as provided in Section 15.4.1(a).

15.4.2 Remedial Plans. If Contractor elects to attempt to satisfy the applicable Performance Guarantees as provided in Section 15.4.1(b), Contractor shall submit a Remedial Plan for such Unit to Owner for review and approval, such approval not to be unreasonably withheld. Each Remedial Plan shall, at a minimum, specify the corrective actions Contractor proposes to take, the commencement date of such corrective action, the component or system that will be tested after such corrective actions are implemented, and the tests that will be performed on such component or system, including any Performance Tests, and any required Outage Periods for such corrective actions and tests. The corrective actions described in the Remedial Plan that Contractor proposes to undertake with respect to the Work must be designed and intended to cause the Project to satisfy the applicable Performance Guarantees without negative effects on Acceptance Tests results used to obtain Substantial Completion, must have a reasonable probability of success, and may not involve a material risk of damaging or diminishing the performance of any of the Work. The projected completion date for such corrective action must fall within the Cure Period. If in any dispute between Owner and Contractor regarding the approval of a proposed Remedial Plan it is determined that Owner’s failure to approve a proposed Remedial Plan was in violation of this Agreement, Contractor’s sole remedy for such violation shall be an equitable extension of the Cure Period, and such failure shall not otherwise be considered a breach of any covenant, condition, representation or warranty of Owner, and shall not be construed as an Owner Event of Default.

15.4.3 Prosecution of Remedial Plan. In the event Contractor elects to attempt to achieve the Performance Guarantees and proceeds with a Remedial Plan, Contractor shall:

(a) promptly and diligently pursue completion of the Remedial Plan at Contractor’s sole cost;

(b) in performing the corrective actions described in the Remedial Plan, neither cause the Project to be unable to meet the Minimum Performance Criteria or satisfy the Emission Guarantees, nor cause the Project to be unable to comply with Applicable Laws; and

15.4.4 Additional Remedial Plans. If Contractor is unable to satisfy the applicable Performance Guarantees after completing the initial Remedial Plan, Contractor may deliver a new Remedial Plan to Owner within ten (10) days after completion of such initial Remedial Plan; provided that the Cure Period has not or will not expire during the period covered by such new Remedial Plan.

EXECUTION COPY

15.4.5 Election of Option. Contractor shall exercise the option provided in Section 15.4.1 by delivery of Notice to Owner not later than ten (10) days after (i) the later of the Substantial Completion Guaranteed Date for such Unit, or (ii) the expiration of a previously implemented Remedial Plan, as applicable. For the avoidance of doubt, Contractor may, notwithstanding Contractor’s election of option (b) of Section 15.4.1 elect to pay the Performance Liquidated Damages pursuant to option (a) of Section 15.4.1 after the expiration of its previously implemented Remedial Plan if Contractor fails to satisfy the applicable Performance Guarantees by such date; provided that the Unit continues to meet the Minimum Performance Criteria.

15.4.6 Buy-Down Not Available. For the avoidance of doubt, if Contractor fails to achieve the Minimum Performance Criteria with respect to the Net Unit Capacity and the Net Unit Heat Rate, Contractor shall not be entitled to pay the Performance Liquidated Damages pursuant to option (a) of Section 15.4.1 to achieve Substantial Completion of a Unit and must continue seeking to satisfy the applicable Performance Guarantees and to achieve Substantial Completion, and shall continue to pay Delay Liquidated Damages with respect to such Unit under Section 15.1 until Contractor achieves Substantial Completion of such Unit.

15.4.7 Access During Cure Period. Upon Substantial Completion of a Unit, Owner shall assume care, custody and control of such Unit in accordance with Section 14.6. Notwithstanding the foregoing, during the Cure Period and upon approval of a Remedial Plan, Owner shall provide Contractor with reasonable access to such Unit Upon Owner’s approval of the Remedial Plan for a Unit, Contractor shall be granted reasonable access to the Unit, subject to Section 15.4.8, for purposes of achieving the Performance Guarantees and for the period as set forth in the Remedial Plan, to:

(a) perform corrective actions pursuant to the Remedial Plan; and

(b) perform the applicable tests, including Performance Tests, as provided in such Remedial Plan.

15.4.8 Operations During Cure Period. During the Cure Period, Owner shall have the right to operate such Unit in its sole discretion, including the right to maximize the economic benefits of such Unit. Contractor understands and accepts that the desire of Owner to maximize the economic benefits of such Unit likely will significantly curtail Contractor’s freedom of action during the Cure Period and Owner will likely not provide access to such Unit to Contractor for any significant modifications during the peak season from June 1 through September 30 of any year. Any failure by Owner to provide Contractor with reasonable access to such Unit during the Cure Period shall not be considered a breach of any covenant, condition, representation or warranty of Owner, and shall not be construed as an Owner Event of Default. Contractor’s only remedy for a failure by Owner to provide Contractor with reasonable access to such Unit during the Cure Period shall be an equitable extension of the Cure Period until such reasonable access is provided.

15.4.9 Shut Downs During Cure Period. Owner and Contractor agree to cooperate in good faith in determining when and to what extent such Unit will be taken out of service in order for Contractor to take corrective actions or perform any tests required as part of

EXECUTION COPY

Contractor’s proposed Remedial Plans during the Cure Period. Owner and Contractor agree to cooperate in good faith to minimize the periods of time during the Cure Period when a Unit will be taken out of service or any material limitations will be imposed on Owner’s operation of such Unit (each such period, an “Outage Period”). Contractor shall use its best efforts to conduct corrective actions during periods when a Unit is undergoing scheduled maintenance outages and Owner agrees to grant Contractor access to such Unit during such scheduled maintenance outage to the extent Contractor’s corrective actions do not unreasonably interfere with Owner’s scheduled maintenance. Unless Owner expressly agrees otherwise (which agreement may be withheld in Owner’s sole discretion for any or no reason), no Outage Period shall be scheduled during the months of June, July, August and September. Notwithstanding the foregoing, Contractor will have the right to at least three (3) Outage Periods not to exceed twenty (20) days in the aggregate, to be scheduled in consultation with Owner pursuant to this Section 15.4.9; provided that any additional Outage Periods shall be subject to Owner’s approval which may be withheld in Owner’s sole and absolute discretion for any or no reason. Each Outage Period will begin after a 24-hour cool down period (if necessary for Contractor’s proposed corrective action) and will end when Contractor restores the Unit to normal operational conditions and turns the Unit over to Owner for operation. Subject to Section 31.2.2, if the duration of an Outage Period exceeds the duration agreed to by the Parties for such Outage Period, Contractor shall pay Owner an amount equal to *** Dollars ($***) for each day in excess of such agreed duration, not to exceed a maximum aggregate amount of *** Dollars ($***); provided, that Contractor shall not pay any amounts pursuant to the foregoing for the additional time that the Unit is out of service beyond the agreed-upon Outage Period if Owner is engaged in a scheduled maintenance outage and in any event would keep the Unit shut down. Accrued amounts of such payments shall be due and payable from time to time within five (5) days after Owner provides a Notice to Contractor demanding payment thereof. If Owner instructs Contractor to cease performing a test of a Unit or conducting corrective actions during an Outage Period or otherwise during the remainder of the Cure Period (for reasons other than safety or other concerns arising from Errors or Omissions or Defects), Contractor shall be granted a day for day extension of the Cure Period.

15.5 Extension of Cure Period. Notwithstanding anything to the contrary herein, in the event Contractor has been unable to meet the applicable Performance Guarantees with respect to a Unit on or prior to the expiration of the initial one hundred eight (180) day Cure Period for such Unit, Contractor may submit to Owner for approval a revised Remedial Plan setting forth in specificity and detail the corrective actions which Contractor proposes to undertake to enable the Unit to achieve the applicable Performance Guarantees during any extended Cure Period. Upon Owner’s approval of such revised Remedial Plan, not to be unreasonably withheld, the Cure Period for such Unit shall be extended for the period of time set forth in the Remedial Plan, but in no event for more than one hundred eighty (180) days; provided, however, that the Unit continues to meet the Minimum Performance Criteria with respect to both Net Unit Capacity and Net Unit Heat Rate; provided, further, that Contractor shall pay the Performance Liquidated Damages due and owing to Owner pursuant to Section 15.3 with respect to such Unit within ten (10) business days of Owner’s approval of such revised Remedial Plan, such Performance Liquidated Damages. Notwithstanding anything to the contrary, in the event the Unit 1 Boiler Upgrade Supplier, Alstom Power Inc., is entitled to an extension of the initial one hundred eighty

*** CONFIDENTIAL MATERIAL REDACTED AND FILED SEPARATELY WITH THE COMMISSION.

EXECUTION COPY

(180) day Cure Period pursuant to the terms of such Boiler Upgrade Supplier’s Boiler Upgrade Contract, and Contractor and such Boiler Upgrade Supplier submit a Remedial Plan requiring an extension that will exceed one hundred eighty (180) days, Owner shall not unreasonably withhold approval of such Remedial Plan and, provided Unit 1 continues to meet the Minimum Performance Criteria with respect to both Net Unit Capacity and Net Unit Heat Rate and Contractor pays the Performance Liquidated Damages as provided in the foregoing sentence, the Cure Period for Un▇▇ ▇ ▇or such Boiler Upgrade Supplier only shall be extended for the period of time set forth in the Remedial Plan, but in no event for more than three hundred sixty (360) days.

15.6 Sole Remedy; Liquidated Damages Not a Penalty. The amounts payable under Sections 15.1 or 15.3, as limited by Article 31, and the other remedies provided for in this Article 15 shall be the sole and exclusive remedies of Owner for delays in Substantial Completion, and for failure of a Unit to meet the Performance Guarantees (other than the Environmental Compliance Guarantees) during the Acceptance Tests, except to the extent a delay in Substantial Completion becomes a Contractor Event of Default pursuant to Section 19.1(g). The Parties agree that Owner’s actual damages, as applicable, in the event of such delays or failures would be extremely difficult or impracticable to determine and that Owner’s estimate of its costs and revenues in the event of such delays or failures significantly exceed the amount of the liquidated damages provided herein. After negotiation, the Parties have agreed that the Delay Liquidated Damages and the Performance Liquidated Damages do not exceed the damages that Owner would incur as a result of such delays or failures and are in the nature of liquidated damages, and not a penalty. For the avoidance of doubt, Contractor shall have an absolute obligation to cause each Unit (subject to Sections 19.3, 31.1 and 31.2): (a) to successfully achieve Mechanical Completion; (b) to successfully achieve the Environmental Compliance Guarantees; and (c) to achieve the Minimum Performance Criteria.

15.7 Enforceability. The Parties explicitly agree and intend that the provisions of this Article 15 shall be fully enforceable by any court exercising jurisdiction over any dispute between the Parties arising under this Agreement. Each party hereby irrevocably waives any defenses available to it under law or equity relating to the enforceability of the liquidated damages provisions set forth in this Article 15.

15.8 True-Up. The Parties acknowledge and agree that the Performance Liquidated Damages, if any, paid upon the extension of the Cure Period for a Unit pursuant to Section 15.5 will be based upon results of the most recent Performance Tests, and that the results of the Performance Tests at the end of the extended Cure Period may vary. Upon completion of the final Performance Tests of such Unit completed during any such extended Cure Period, the Parties shall meet and review the results of such Performance Tests. If the amounts paid as Performance Liquidated Damages pursuant to Section 15.5 are less than the amounts that Contractor should have paid based on the results of the final Performance Tests of such Unit completed during such extended Cure Period, Contractor shall pay to Owner such deficiency within ten (10) days after the Parties agree on such results. If the amounts paid as Performance Liquidated Damages pursuant to Section 15.5 exceed the amounts that Contractor should have paid based on the final Performance Test results of such Unit completed during such extended Cure Period, Owner shall refund to Contractor such excess within ten (10) days after the Parties agree on such results.

Contractor and Owner acknowledge and agree that as of the date hereof Contractor is negotiating amendments and modifications to the STG Upgrade Contract with the STG Upgrade Supplier. Notwithstanding anything to the contrary herein, Contractor acknowledges and agrees that Contractor shall not be entitled to a Change In Work with respect to any such amendment or modification to the STG Upgrade Contract; provided that Contractor may be entitled to a Change

EXECUTION COPY

in Work to the extent such amendment or modification is made in connection with resolution of an open item identified on Exhibit DD.

16.2 By Owner. Owner shall have the right to make changes in the Work, within the general scope thereof, whether such changes are modifications, accelerations, alterations, additions, or deletions. All such changes shall be made in accordance with this Article 16, be documented in accordance with Section 16.4 and shall be considered, for all purposes of this Agreement, as part of the Work.

16.3 Adjustment to Substantial Completion Guaranteed Dates and Separated Contract Price Due to Certain Events.

16.3.1 Adjustments to Substantial Completion Guaranteed Dates. If an Excusable Event occurs, the Project Schedule (and the Substantial Completion Guaranteed Dates referenced therein) shall be extended as and to the extent provided in Section 8.6.2 and as set forth in the Change In Work Form accepted by Owner. If an event of Force Majeure occurs, the Project Schedule (and the Substantial Completion Guaranteed Dates referenced therein) shall be extended as and to the extent provided in Section 8.6.1 and as set forth in a Change In Work Form accepted by Owner. If an event described in Section 16.1(g) occurs, the Project Schedule (and the Substantial Completion Guaranteed Date referenced therein for Un▇▇ ▇ ▇r Unit 2, as applicable) shall be equitably extended as necessary for the repair of such welds and as set forth in a Change In Work Form accepted by Owner; provided that Contractor uses all reasonable efforts to mitigate the duration of any delay in achieving the Substantial Completion Guaranteed Date. If an event described in Section 16.1(h) occurs, the Project Schedule (and the Substantial Completion Guaranteed Date referenced therein for Un▇▇ ▇ ▇nd Unit 2, as applicable) shall be equitably extended to the extent necessary to complete such scope of work and as set forth in a Change In Work Form accepted by Owner; provided that Contractor uses all reasonable efforts to mitigate the duration of any delay in achieving the Substantial Completion Guaranteed Date.

16.3.2 Adjustments to Separated Target Price and Separated Contract Price. In the event of an Excusable Event, or the occurrence of an event of Force Majeure that delays the Work for five (5) or more consecutive days or of multiple events of Force Majeure that delays the Work for more than fifteen (15) days in the aggregate, the Separated Target Price or the Separated Contract Price, as applicable, shall be adjusted by the sum of: (i) the difference of the direct costs (without profit, overhead or contingency), including third party costs, incurred by Contractor because of such Change In Work; less any savings or costs not incurred because of such Change In Work; plus (ii) an allowance for profit in accordance with Exhibit Y; provided that Contractor shall be entitled to a Change In Work adjusting the Separated Target Price or the Separated Contract Price, as applicable, only to the extent Contractor can reasonably demonstrate that the Separated Target Price or the Separated Contract Price, as applicable, is affected by such Excusable Event or event of Force Majeure.

16.3.3 Adjustments to Separated Contract Price. If an event described in Section 16.1(i) occurs, the Separated Contract Price shall be adjusted by an amount equal to the Craft Labor Compensation Escalation Amount pursuant to a Change In Work reflecting such amount.

EXECUTION COPY

approve such an increase, Contractor may submit a Change In Work to adjust the Substantial Completion Guaranteed Dates for Unit 1 or Unit 2, as applicable, and to adjust the Separated Contract Price. If Contractor is entitled to submit a Change In Work pursuant to the foregoing sentence, the Substantial Completion Guaranteed Date for Unit 1 or Unit 2, as applicable, shall be equitably adjusted pursuant to a Change In Work by the amount of time Contractor is actually and demonstrably delayed in the performance of the Work due to the lack of sufficient qualified craft labor personnel, and such Change In Work may also adjust the Separated Contract Price to the extent Contractor can reasonably demonstrate that Contractor will incur additional costs (but not including any increases in Craft Labor Compensation) not included in the Separated Contract Price as a direct result of such change in such Substantial Completion Guaranteed Dates.

16.4 Preparation of Change In Work Form.

Notwithstanding the foregoing, during the period that Contractor has care, custody and control of a Unit, any adverse stress or damage to the Equipment and Materials caused by Operating Personnel while under the direction of Contractor shall be the responsibility of Contractor, except to the extent such Operating Personnels’ acts or omissions constitute gross negligence or willful misconduct.

Further, Contractor shall have no warranty obligation or liability for Defects or deficiencies in the Work if Contractor reasonably demonstrates that the Defect or deficiency is attributable to Contractor’s reliance upon or use of design criteria, drawings or specifications provided by Owner expressly for use in the performance of the Work.

17.6 Subcontractor Warranties. Contractor shall obtain warranties for all Work performed by each Subcontractor on terms at least as favorable as this Article 17.

17.7 Correction of Errors or Omissions and Defects.

17.7.1 Notice of Warranty Claim. Subject to Section 17.7.5, Owner shall provide Notice to Contractor within a reasonable period after discovery that any of the Work fails to satisfy the Work Warranty or the Materials Warranty during the applicable Warranty Period. Contractor shall, at Contractor’s own cost and expense (including overtime, but excluding insurance proceeds to the extent actually received) refinish, repair or replace, at its option, such nonconforming or defective part of the Work, within its original Scope of Work, including re-performing any necessary engineering and purchasing relating to such Work, and shall pay the cost of removing any Error or Omission or Defect and the cost of re-performing, repairing, replacing or testing such subject Work, including any damage to the surrounding Work (subject to the limitations provided in Section 22.2), as shall be necessary to cause the Work and the Project to conform to the Work Warranty or Materials Warranty. In addition, subject to the limitations provided in Section 22.2, Contractor shall, at its own cost and expense (including overtime, but excluding insurance proceeds to the extent actually received), repair and replace any portion of the Work that is damaged or destroyed because any of the Work shall fail to satisfy the Work Warranty or the Materials Warranty during the applicable Warranty Period, all in accordance with the Warranty Procedures. Within five (5) Business Days after receipt by Contractor of a Notice from Owner delivered during the Warranty Period specifying a failure of any of the Work to satisfy Contractor’s Work Warranty or the Materials Warranty and requesting Contractor to correct the failure, Contractor and Owner shall mutually agree when and how Contractor shall remedy such failure (the “Warranty Procedures”). The timing of and the Work to be completed with respect to any such remediation or repair shall be subject to Owner’s approval. No such remediation or repair shall be considered complete until Owner shall have reviewed and approved such completed remedial work. Notwithstanding the foregoing and subject to Section 17.7.2.2, if any of the Work shall fail to satisfy Contractor’s Work Warranty or the Materials Warranty, and such failure endangers human health or property or materially and adversely affects the operation of the Project, Contractor shall correct the failure as soon as is reasonably practicable.

17.7.2 Owner Performance.

17.7.2.1 Upon Contractor’s Request. Notwithstanding the foregoing, Contractor may request Owner to perform all or any portion of Contractor’s obligations with respect to any warranty claim. Upon such request, Owner may elect to perform such obligations in Owner’s sole discretion, and if Owner elects not to perform such obligations, Contractor shall remain obligated to and shall perform such obligations. Contractor shall reimburse Owner for all costs and expenses incurred by Owner (including costs of Owner’s personnel, but excluding overhead, corporate burdens, profit, and the like) to perform Contractor’s obligations with respect to such warranty claim within ten (10) Business Days of receiving Owner’s request for payment of such costs.

17.7.2.2 Failure of Contractor to Perform Warranty Work. If Contractor does not use its reasonable efforts to proceed to complete the Work, or cause any relevant

EXECUTION COPY

Subcontractor to proceed to complete the Work, required to satisfy any warranty claim properly asserted under the terms of this Article 17 within the agreed time, or if Contractor and Owner fail to reach such an agreement within such five (5) day period set forth in Section 17.7.1, Owner shall, after giving Contractor at least five (5) days prior Notice of Owner’s intent to perform the remedy itself, have the right to perform the necessary remedy, or have third parties perform the necessary remedy and Contractor shall bear the reasonable costs thereof. If Contractor (or the relevant Subcontractor) begins to perform the Work to satisfy such warranty claim during such five (5) day period, Owner shall not perform, or cause any third party to perform, such remedy. In the event any of the Work fails to satisfy the Work Warranty or the Materials Warranty during the applicable Warranty Period and any such failure occurs under circumstances in which there is an immediate need for repairs, Owner may perform such warranty work for Contractor’s account; provided that Owner provides reasonably prompt Notice to Contractor of such immediate need.

17.7.3 Replaced Components Demonstrations. If, during the Warranty Period, Contractor changes, repairs or replaces any Equipment and Materials (any such item changed, repaired or replaced, a “Component”), Contractor and Owner shall mutually agree on how to demonstrate to Owner, taking into consideration Owner’s reasonable requirements, that such Component meets the intent of the Project design conditions.

17.7.4 Continual Failure of Component. Should Contractor fail to correct any Error or Omission or Defect in the Work during the Warranty Period that results in a Component failing more than once to meet the Work Warranty or the Material Warranty during the Warranty Period, Owner shall provide Notice to Contractor of such failure, Contractor shall determine what changes, repairs or replacements to the Component are necessary to correct the Error or Omission or Defect or avoid further failures of such Component, and shall make such necessary changes, repairs or replacements. In each case, during the Warranty Period Contractor shall repeat such process on an iterative basis until the Error or Omission or Defect and the underlying cause thereof or of the continuing failure is corrected.

17.7.5 Owner’s Warranty Option. Owner and Contractor acknowledge and agree that it may be impracticable or otherwise not in Owner’s best interest to re-perform any Work or fix any defective Equipment and Materials which fails to satisfy the Work Warranty or Materials Warranty pursuant to the provisions of Section 17.7.1. Such impracticability may be due to, among other things, considerations concerning the length of time a Unit may be shutdown in order to re-perform such nonconforming Work or risks to the other portions of the Project as a result of such re-performance. As a consequence thereof, the Parties expressly agree that in lieu of re-performing any Work so as to cause the Project to satisfy the Work Warranty and Materials Warranty, Owner shall have the option (the “Warranty Payment Option”) (which option Owner shall exercise (if at all) by Notice to Contractor within ten (10) days after Owner initially Notifies Contractor of such non-conforming Work pursuant to the first sentence of Section 17.7.1) to require Contractor to pay to Owner, in lieu of re-performing such Work, an amount equal to the estimated cost to Contractor to re-perform any necessary engineering and purchasing relating to such non-conforming Work, plus the cost of removing any non-conforming Work and the cost of re-performing, repairing or replacing such subject Work, including any damage to the surrounding Work (subject to the limitations provided in Section 22.2), all as would be necessary to cause the Work and or the applicable Equipment and

EXECUTION COPY

Materials to conform to the Work Warranty and Materials Warranty. If Owner exercises its Warranty Payment Option with respect to any non-conforming Work, Contractor shall provide its estimated costs to Owner for approval within ten (10) days of receipt of Notice from Owner that Owner has exercised the Warranty Payment Option, and shall pay all such estimated costs, as approved by Owner, to Owner within ten (10) Business Days after Notice of such demand from Owner. If Owner exercises its Warranty Payment Option with respect to any non-conforming Work, and Contractor pays all such costs with respect to such non-conforming Work, Contractor’s warranty obligations hereunder with respect to such non-conforming Work shall be deemed satisfied.

17.8 Limitations On Warranties. EXCEPT FOR THE EXPRESS WARRANTIES AND REPRESENTATIONS SET FORTH IN ARTICLE 4, THIS ARTICLE 17 AND SECTION 25.4, CONTRACTOR DOES NOT MAKE ANY OTHER EXPRESS WARRANTIES OR REPRESENTATIONS, OR ANY IMPLIED WARRANTIES OR REPRESENTATIONS, OF ANY KIND, INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR PURPOSE. THE REMEDIES PROVIDED FOR IN THIS ARTICLE 17 WITH RESPECT TO ANY WORK WHICH FAILS TO SATISFY THE WORK WARRANTY OR THE MATERIALS WARRANTY DURING THE WARRANTY PERIOD, AND IF SUCH FAILURE CONSTITUTES A CONTRACTOR EVENT OF DEFAULT, THE REMEDIES PROVIDED FOR IN SECTIONS 19.2(B) AND 19.2(D) THROUGH 19.2(G), SHALL BE THE SOLE AND EXCLUSIVE REMEDIES FOR OWNER AS A RESULT OF SUCH FAILURE.

18. EQUIPMENT IMPORTATION; TITLE

EXECUTION COPY

18.2.2 Transfer. Title to all Equipment and Materials and other items, other than the Owner Furnished Equipment and the Leased Equipment, shall pass to Owner, and with respect to the Owner Furnished Equipment, shall be retained by Owner, free and clear of all liens, claims, charges, security interests, and encumbrances whatsoever, except for those encumbrances which may be created by action of Owner associated with any financing of, upon delivery of such Equipment and Materials or other items to the Project and payment by Owner to Contractor therefor.

Owner may in its sole discretion terminate the Work with or without cause at any time by giving Notice of termination to Contractor, to be effective upon the receipt of such Notice by Contractor or upon such other termination date specifically identified by Owner therein. If this Agreement is terminated pursuant to this Section 20.1 after the Open Book Review has been concluded and the Separated Contract Price has been agreed to by the Parties, as compensation for the Work performed through the effective date of termination, subject to reductions as set in this paragraph below, Owner shall pay to Contractor an amount equal to the sum of (g) the reasonable cost of the Work properly performed in accordance with this Agreement to the date of termination based on the Schedule of Payment Values (and pro-rated if necessary); plus (h) Contractor’s reasonably incurred out-of-pocket- costs of demobilization (as evidenced in writing) including

EXECUTION COPY

demobilization and termination or cancellation or breakage costs of Subcontractors if their agreements with Contractor are not assigned to and assumed by Owner pursuant to Section 20.1.3; less (i) any amounts previously paid to Contractor under this Agreement.

Contractor shall not include any cancellation fees of Contractor in the Schedule of Payment Values or the estimated cancellation costs, and shall not be entitled to receive any cancellation fees.

20.1.2 Limitation on Payment. Except as provided in this Section 20.1, Contractor shall not be entitled to any lost profit upon any termination of this Agreement.

20.1.3 Owner’s Right to Elect to Assume Obligations with Subcontractors. In addition, Owner shall have the right, at its sole option, to assume and become liable for any written obligations and commitments that Contractor may have in good faith undertaken with third-parties in connection with the Work to be performed at the Site. If Owner elects to assume any obligation of Contractor as described in this Section 20.1.3, then (a) the amount paid pursuant to Section 20.1.1 shall be reduced by the amount of such obligations and commitments (unless they relate to termination or demobilization costs or to payments due for work already completed for which Contractor remains obligated to pay); (b) Contractor shall execute all assignments or other documents and take all other reasonable steps requested by Owner which may be required to vest in Owner all rights, set-offs, benefits and titles necessary to such assumption by Owner; (c) Contractor’s satisfaction of its obligations under this Section 20.1.3 shall be a condition precedent to Owner’s obligation to comply with its obligations under this Section 20.1 (including its obligation to make any payment to Contractor); and (d) Owner shall simultaneously agree to indemnify Contractor against liabilities thereafter arising under the assumed obligations or commitments.

20.2 Contractor Conduct. Upon receipt of written notice from Owner of termination pursuant to Section 20.1, Contractor shall: (a) cease operations as directed by Owner in the notice; (b) take action necessary, or that Owner may direct, for the protection and preservation of the Work and the Project; and (c) except for Work directed to be performed prior to the effective date of termination stated in notice, or except as expressly requested by Owner in writing, terminate all existing subcontracts and purchase orders and enter into no further subcontracts or purchase orders with respect to the Work or the Project.

The payments described in Section 20.1 include payment for: (a) all costs of Equipment and Materials, temporary equipment, labor, transportation, engineering, design and other services relating to Contractor’s performance of its obligations under this Agreement and said Owner-requested Work (including any intellectual property rights licensed under this Agreement, expressly or by implication) provided by Contractor or such Subcontractors; (b) all national, state, regional and local taxes, and other sales

The taxes covered hereby include occupational, excise, unemployment, ownership, value-added, gross receipts, and any and all other taxes and duties on any item or service that is part of the Work, whether such tax is normally included in the price of such item or service or is normally stated separately. The above-described payments shall not be increased with respect to any of the foregoing or with respect to any withholdings in respect of any of the foregoing items that Owner may be required to make.

20.4 Suspension by Owner. Owner may suspend performance of the Work at any time by giving ten (10) days advance Notice thereof to Contractor. Such suspension shall continue for the period specified in the suspension Notice. The Separated Contract Price shall be adjusted as provided in clause (b) of Section 20.4.2 to reflect any additional increased costs of Contractor resulting from any such suspension, as demonstrated by Contractor to Owner’s reasonable satisfaction. No adjustment shall be made to the extent that performance is suspended, delayed, or interrupted for any cause due to Contractor’s negligence, willful misconduct, or noncompliance with the material terms of this Agreement. At any time after the effective date of the suspension, Owner may require Contractor to resume performance of the Work on seven (7) days prior Notice.

20.4.1 Contractor’s Termination Right. Subject to Applicable Law, if, at the end of the suspension period specified pursuant to Section 20.4, Owner has not requested a resumption of the Work or has not notified Contractor of any extension of the suspension period (but in no event beyond one hundred eighty (180) days in the aggregate for all such suspensions, other than suspensions for any reason due to Contractor’s negligence, willful misconduct or noncompliance with the material terms of this Agreement) at Contractor’s option this Agreement shall be deemed terminated as of the commencement date of the suspension period, and Owner shall promptly pay Contractor for the Work performed pursuant to Section 20.1. In the event the Full Notice to Proceed has not been issued by December 31, 2007, Contractor may, upon ten (10) days prior Notice to Owner, terminate this Agreement and Owner shall pay Contractor for the Work performed pursuant to Section 20.1. Notwithstanding anything to the contrary herein, Contractor shall not be entitled to terminate this Agreement regardless of the number of days a Suspension for Cause (as defined in Section 20.6) may extend.

20.4.2 Extension of Time and Compensation Rights. In the case of any suspension under this Section 20.4 or any suspension by Contractor under Section 19.5, other than a Suspension for Cause (as defined below):

(a) the applicable Substantial Completion Guaranteed Dates shall be extended by a period no less than the suspension period, plus a reasonable period for demobilization and remobilization, as mutually agreed upon by Contractor and Owner;

(b) Owner shall pay Contractor within thirty (30) days after receipt of each Contractor’s invoice (which invoices shall be submitted on or about the first (1^st) and the

EXECUTION COPY

fifteenth (15^th) day of each month during the applicable suspension period) for those costs incurred during the suspension period that are documented by Contractor to the reasonable satisfaction of Owner, to the extent attributable to the suspension, and that are:

(i) for the purpose of safeguarding or storing the Work and the Equipment and Materials at the point of fabrication, in transit, or at the Site;

(ii) for personnel, Subcontractors, or rented Equipment and Materials, the payments for which, with Owner’s prior written concurrence, are continued during the suspension period;

(iii) for reasonable costs of demobilization and remobilization of Contractor and its Subcontractors, including suspension costs set forth in any subcontract or purchase order; or

(iv) for rescheduling the Work (including penalties or additional payments to Subcontractors for the same); and

(c) the Project Schedule, the Milestone Items and the Schedule of Payment Values shall be adjusted to account for same, as mutually agreed upon by Contractor and Owner.

20.5 Claims for Payment. All claims by Contractor for compensation or extension of time under Sections 20.1 and 20.4 must be made within forty-five (45) days after the Work has been terminated or the suspension period has ended, respectively. Failure of Contractor to make such claim within said period shall be deemed a waiver by Contractor of any such claims.

20.6 Suspension for Cause. Notwithstanding the foregoing, neither the Separated Contract Price nor any Substantial Completion Guaranteed Date shall be adjusted for a Suspension for Cause. Any suspension shall be a “Suspension for Cause” if:

(i) a Contractor Event of Default shall have occurred and is continuing hereunder; or

(ii) in the case of a suspension due to the occurrence of a Contractor Event of Default identified in Section 19.1(b), Owner shall have given Notice of such default to Contractor, at least five (5) days shall have elapsed since delivery of such Notice and Contractor shall have failed to cure, or if such default cannot reasonably be cured within such five (5) day period, commenced to cure, such default within such five (5) days.

21. INSURANCE

21.1 Owner Controlled Insurance Program.

21.1.1 OCIP Coverages.

The OCIP

EXECUTION COPY

will provide workers compensation, employers liability, commercial general liability, excess liability and builders’ risk coverage (including inland/marine transit coverage). The OCIP is intended to reduce the cost of completing the Project and does not constitute any representation by Owner with respect to the adequacy of the insurance to protect Contractor or the Subcontractors against obligations imposed by law or by this Agreement or any other contract. Except as otherwise provided in this Agreement, neither the provision of the insurance described in this Section 21.1 nor the extent of coverage or the limits of liability under such insurance policies shall be construed to be a limitation on the nature or extent of Contractor’s or the Subcontractors’ obligations or to relieve Contractor or the Subcontractors of any such obligations.

21.1.2 OCIP Costs. Contractor has excluded from the Separated Target Price and shall exclude from the Separated Contract Price and any Change In Work Forms all charges for insurance costs which duplicate the coverage provided under the OCIP. Contractor shall include a provision in its subcontracts requiring Subcontractors of all tiers that are eligible to participate in the OCIP to exclude from their subcontract price and any Change In Work Forms all charges for insurance coverages which duplicate the coverage provided under the OCIP. Notwithstanding anything to the contrary in the foregoing, if Owner elects not to include an eligible Subcontractor in the OCIP, a Change In Work Form may be submitted to adjust the Separated Target Price or Separated Contract Price, as applicable, to account for such Subcontractor’s insurance costs.

21.1.3 OCIP Deductibles. Contractor shall, or shall cause its Subcontractors to, pay deductibles under the workers’ compensation and employers’ liability OCIP policies, up to Two Hundred Fifty Thousand Dollars ($250,000) per occurrence and Two Hundred Fifty Thousand Dollars ($250,000) annual aggregate. Contractor shall, or shall cause its Subcontractors to, pay deductibles under the commercial general liability OCIP policy, up to Two Hundred Fifty Thousand Dollars ($250,000) per occurrence and Two Hundred Fifty Thousand Dollars ($250,000) annual aggregate, when coverage is provided thereunder for a loss for which Contractor is responsible under Section 23.1.

21.1.4 Participation. The OCIP shall include coverage for Owner, Contractor and the Subcontractors that are eligible to participate in the OCIP, including Subcontractors providing temporary labor services, taking part in or contributing to the actual Work at the Site who complete enrollment in the OCIP and are accepted by Owner. Coverage under the OCIP insurance policies shall be limited to the Site and the Ancillary Sites, and as regards the builders’ risk coverage shall extend to the Owner Furnished Equipment while located at the Ancillary Sites, but shall not, in any event, include any of Contractor’s and any Subcontractor’s regularly established workplace, plant, factory, office, shop, warehouse, yard or other property, even if utilized in the fabrication of Equipment and Materials to be incorporated into the Project. Subcontractors that do not actually perform Work at the Site such as Persons that provide security or janitorial services or that deliver Equipment and Materials to the Site but do not otherwise engage in any of the Work at the Site, shall not be eligible to participate in the OCIP. Any Subcontractors that are on the Site for a cumulative amount of time less than two weeks, and any Subcontractors whose subcontract has a cumulative value of less than Twenty Five Thousand Dollars ($25,000) shall not be eligible to participate in the OCIP unless approved by Owner in writing.

21.5 Insurance Coverages. All amounts of insurance coverage specified in Exhibits N-1 and N-2 are required minimums.

The required minimum amounts of insurance shall not operate as limits on recoveries available under this Agreement.

21.6 Failure to Maintain Insurance. If at any time the insurance required to be provided hereunder by Contractor or any Subcontractor shall be reduced or cease to be maintained, then (without limiting the rights of Owner in respect of any default that arises as a result of such failure) Owner may at its option maintain the insurance required hereby upon written notice to Contractor and ten (10) days opportunity to cure.

Notwithstanding the foregoing, if any portion of a Unit or the Project is lost or damaged after Substantial Completion due to any negligent act or omission of Contractor, any Affiliate of Contractor or any Subcontractor, or anyone directly or indirectly employed by any of them, Contractor’s liability for replacing or repairing such loss or damage shall be limited in amount to the amount of such loss or damage, not to exceed $250,000 per occurrence and $250,000 in any given year, regardless of whether or not Owner carries insurance coverage for such loss or damage. In any event, the care, custody, and control of each Unit shall pass to Owner no later than the Substantial Completion Date of such Unit. From and after the Substantial Completion Date of such Unit, Owner shall assume all risks of physical loss or damage thereto, subject to Contractor’s obligation to pay the costs of losses or damage to the Unit to the extent caused by any negligent act or omission of Contractor or any of its Subcontractors, not to exceed $250,000 per occurrence and $250,000 in any given year.

(h) all Losses, including claims for property damage or bodily injury or death, whether or not involving damage to the Project or the Site or any Ancillary Site, that arise out of or result from the use of Hazardous Materials, whether lawful or unlawful, brought onto the Site or any Ancillary Site by Contractor or any Subcontractor. Such use of or contamination by Hazardous Materials include:

(i) the storage, transportation, processing or disposal of such Hazardous Materials; and

(ii) any environmental condition caused by such Hazardous Materials; and

(i) all Losses incurred in connection with the Agency Subcontracts related to matters in which Contractor acted outside the scope of its agency pursuant to Section 3.23, including failure to make payments to such Suppliers (provided Owner has paid Contractor).

23.2 By Owner. Owner shall defend, indemnify, and hold harmless Contractor, its Subcontractors and any Person acting for or on behalf of Contractor and their respective employees, agents, partners, Affiliates, shareholders, directors, officers, and assigns (each an “Contractor Indemnitee”) from and against the following:

(a) all Losses arising from third-party claims for property damage or bodily injury or death to the extent caused by any negligent, reckless, or otherwise tortious act or omission (including strict liability) during the performance of Owner’s obligations under this Agreement, of Owner or any of Owner’s Affiliates, or anyone directly or indirectly employed by any of them (but not including Operating Personnel prior to Substantial Completion), or anyone for whose acts such Person may be liable (but not including Operating Personnel prior to Substantial Completion);

(b) all Losses arising from claims by any Governmental Authority that directly or indirectly arise out of or result from the failure of Owner to pay, as and when due, all taxes, duties, levies, assessments, tariffs, imposts, fees or charges of any kind (together with any and all interest, penalties, additions to tax and additional amounts imposed with respect thereto) imposed by any Governmental Authority for which Owner is obligated to pay pursuant to the terms of this Agreement;

(c) all Losses, including claims for property damage or bodily injury or death that directly or indirectly arise out of or result from:

(i) the presence or existence of Hazardous Materials (including pre-existing contamination) at the Site or any Ancillary Site (A) brought onto or generated at the Site or such Ancillary Site on or before the date of the Original Agreement; (B) brought onto or generated at the Site by Owner or such Ancillary Site (other than Hazardous Materials that were brought onto the Site or the Ancillary Sites or delivered to Contractor or any Subcontractor to be

EXECUTION COPY

handled by the same in the course of performing the Work); or (C) which migrated onto the Site from another location (other than such Hazardous Materials that were previously in the care, custody or control of Contractor or any Subcontractor), except to the extent the remediation of any such Hazardous Materials is part of the Work; or

(ii) the unlawful release or spill by Owner or its Affiliates after the Substantial Completion Date of Hazardous Materials otherwise brought onto the Site by Contractor or any Subcontractor in accordance with the terms of this Agreement and all Applicable Laws;

(d) All Losses incurred in connection with damage to property other than the Project owned by or in the possession of any of the Owner Indemnitees, in excess of the deductible under any such Owner Indemnitees’ applicable insurance policy not to exceed Five Million Dollars ($5,000,000), whether or not caused by the acts, omissions, fault or negligence of Contractor or its Subcontractors; and

(e) Until assignment and assumption of such Agency Subcontracts, Owner shall indemnify Contractor and the Contractor Indemnitees against all Losses incurred in connection with the Agency Subcontracts related to the period prior to the date on which Contractor assumed such agreements, including Losses arising out of claims by the Suppliers under the Agency Subcontracts for payment and cancellation costs, except to the extent such claims or Losses related to matters in which Contractor acted outside the scope of its agency pursuant to Section 3.23, including Contractor’s failure to pay such Suppliers after receiving payment therefor from Owner.

23.3 Patent Infringement and Other Indemnification Rights. Contractor shall defend, indemnify, and hold harmless the Owner Indemnitees against all Losses arising from any Intellectual Property Claim. If Owner provides Notice to Contractor of the receipt of any such claim, Contractor shall, in addition, at its own expense settle or defend any such Intellectual Property Claim and pay all damages and costs awarded in it against Owner and either; (a) procure for Owner, or reimburse Owner for procuring, the right to continue using the infringing service, Equipment and Materials, or other Work, as the case may be; (b) modify the infringing service, Equipment and Materials, or other Work, as the case may be, so that the same becomes non-infringing; or (c) replace the infringing service, Equipment and Materials, or other Work, as the case may be, with noninfringing service, Equipment and Materials, or other Work, as the case may be. If Owner is enjoined from completing the Project or any part thereof, or from the use, operation, or enjoyment of the Project or any part thereof, as a result of such claim or legal action or any litigation based thereon, Contractor shall promptly use its best efforts to have such injunction removed and to take one or more of the actions under the preceding clauses (a), (b) or (c), provided, that in no case shall Contractor take any action which materially adversely affects Owner’s continued use and enjoyment of the applicable service, Equipment and Materials, or other Work, as the case may be, without the prior written consent of Owner. Owner’s acceptance of the Contractor Deliverables or supplied Materials and Equipment shall not be construed to relieve Contractor of any obligation hereunder.

23.4 Use of Electronic Data Files. Any electronic data files furnished to Owner pursuant to this Agreement are provided only for the convenience of Owner. Owner recognizes

EXECUTION COPY

that the electronic data files may not be adequate or appropriate for Owner’s needs. In the case of any discrepancies between the Submittals represented by electronic data files and the plotted hardcopy of such files bearing the seal of Contractor’s registered professional engineer, the sealed hardcopy shall govern. Contractor assumes no responsibility for the accuracy or completeness of the electronic data files and any use or reuse of such electronic data for any purpose shall be at Owner’s sole risk. Furthermore, in consideration for the use of the electronic data, Owner agrees, to the fullest extent permitted by law, to defend, indemnify and hold Contractor harmless from any and all claims, damages, losses, costs, and expenses, including reasonable attorneys’ fees and court costs (including the costs of any appeals) arising out of or resulting from Owner’s use, reuse, of such electronic data regardless of whether such claims, damages, losses, costs, and expenses are caused in whole or in part by Contractor.

23.5 Claim Notice. An Indemnitee shall provide Notice to the indemnifying party, within ten (10) days after receiving written notice of the commencement of any legal action or of any claims or threatened claims against such Indemnitee in respect of which indemnification may be sought pursuant to the foregoing provisions of this Article 23 or any other provision of this Agreement providing for an indemnity (such notice, a “Claim Notice”). The Indemnitee’s failure to give, or tardiness in giving, such Claim Notice will reduce the liability of the Indemnifying Party only by the amount of damages proven to be attributable and prejudicial to such failure or tardiness, but shall not otherwise relieve the indemnifying party from any liability that it may have under this Agreement. In case any such claim or legal action shall be made or brought against an Indemnitee and such Indemnitee shall Notify (by sending a Claim Notice) the indemnifying party thereof, and the Indemnitee may by such Claim Notice require the indemnifying party to assume and control the defense of the claim that is the subject of such Claim Notice, in which case the indemnifying party may select counsel after consultation with the Indemnitee, and the indemnifying party shall pay all expenses of the conduct of such defense. The Indemnitee shall have the right to employ separate counsel in any such proceeding and to participate in (but not control) the defense of such claim, but the fees and expenses of such counsel shall be borne by the Indemnitee unless the indemnifying party shall agree otherwise; provided, however, if the named parties to any such proceeding (including any impleaded parties) include both the Indemnitee and the indemnifying party, the indemnifying party requires that the same counsel represent both the Indemnitee and the indemnifying party, and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, then the Indemnitee shall have the right to retain its own counsel at the cost and expense of the Indemnifying Party. If the indemnifying party shall have failed to assume or diligently prosecute the defense of any claim in accordance with the provisions of this Section 23.5, then the Indemnitee shall have the absolute right to control the defense of such claim and the fees and expenses of such defense, including reasonable attorneys’ fees of the Indemnitee’s counsel and any reasonable amount determined to be owed by Indemnitee pursuant to such claim, shall be borne by the indemnifying party, provided that the indemnifying party shall be entitled, at its expense, to participate in (but not control) such defense. Subject to all of the foregoing provisions of this Section 23.5, (a) the indemnifying party shall control the settlement of all claims, in coordination with any insurer as required under the applicable insurance policies set forth in Exhibit N-1 or Exhibit N-2, as applicable, as to which it has assumed the defense; provided, however, that (i) such settlement shall include a dismissal with prejudice of the claim and an explicit and unconditional release from the party bringing such claim or other proceedings of all Indemnitees; and (ii) the indemnifying party shall

EXECUTION COPY

100

not conclude any settlement without the prior approval of the Indemnitee, which approval shall not be unreasonably withheld; and (b) except as provided in the preceding sentence concerning the indemnifying party’s failure to assume or to diligently prosecute the defense of any claim, no Indemnitee seeking reimbursement pursuant to the foregoing indemnity shall, without the prior written consent of the indemnifying party, settle, compromise, consent to the entry of any judgment in or otherwise seek to terminate any action, claim, suit, investigation or proceeding for which indemnity is afforded hereunder unless such Indemnitee reasonably believes that the matter in question involves potential criminal liability against such Indemnitee. The Indemnitee shall provide reasonable assistance to the indemnifying party when the indemnifying party so requests, at the indemnifying party’s expense, in connection with such legal action or claim, including executing any powers-of-attorney or other documents required by the indemnifying party with regard to the defense or indemnity obligations.

23.6 Survival of Indemnity Obligations. The indemnities set forth in this Article 23 shall survive completion of the Work or the earlier termination of this Agreement for a period expiring five (5) years following the Final Completion Date or said termination, whichever first occurs. All Claim Notices must be delivered, if at all, to the applicable Party prior to the expiration of such five (5) year period. If any Claim Notice is made within such five (5) year period, then the indemnifying period with respect to all claims identified in such Claim Notice (and the indemnity obligation of the Parties hereunder with respect to such claim) shall extend through the final, non-appealable resolution of such claims. For purposes of clarification hereunder, without limiting the other rights granted hereunder to either Party, a Party may enforce the indemnity provisions hereunder pursuant to the provisions of Article 32 without having to declare an Owner Event of Default or a Contractor Event of Default, as applicable.

24. TREATMENT OF CONFIDENTIAL INFORMATION

24.1 Confidential Information. Any Confidential Information is disclosed in confidence, and the transferee shall restrict its use of such information solely to uses related to the Project or performance of this Agreement and shall not use the Confidential Information in any way detrimental to the transferor or its stockholders, including, without limitation, to gain a competitive advantage with the businesses of the transferor. The transferee shall not publish or otherwise disclose any Confidential Information received to others without the prior written approval of the transferor, including the fact that the Confidential Information has been made available to the transferee, that it has entered into this Agreement, or any of the terms, conditions, or other facts with respect to this Agreement. Contractor shall disclose only such Confidential Information to those of its Subcontractors (of all tiers) and its and their Affiliates as is necessary to carry out the purposes of this Agreement. Contractor shall require each of its Subcontractors and their Affiliates to abide by the terms and conditions relating to Confidential Information contained herein. Contractor shall inform its Subcontractors and Affiliates of the confidential nature of the Confidential Information and shall indemnify Owner for any acts or omissions by Contractor or its Subcontractors or their Affiliates with respect to the Confidential Information provided by Owner. Nothing herein shall limit: (a) the right of Owner to provide any information regarding Contractor, any Subcontractor, this Agreement, or the Work to its legal, technical and other officers, its then existing or prospective successors or assigns or any Financing Entity (or advisors retained on their behalf) or its successors and assigns; (b) the right of either Party to supply such information to any Governmental Authority as may be required by

EXECUTION COPY

101

Applicable Law or any securities exchange; or (c) the right of Owner to reproduce and use as many copies of any Submittals or other documents provided to Owner as Owner in its sole discretion considers useful or necessary for the furtherance of the Work, operation and maintenance of the Project, or otherwise related to the Project, regardless of any notices, legends, or disclaimers on such Submittals or other documents. No right or license is granted to Contractor or any third-party respecting the use of such Confidential Information by virtue of this Agreement, except to the extent required for Contractor’s performance of its obligations hereunder. Contractor shall deliver all Owner’s Confidential Information, including all copies thereof, to Owner upon request. The transferee’s obligations regarding Confidential Information shall extend to all derivatives or references to such Confidential Information that are incorporated in any documentation prepared by the transferee in connection with the Work.

24.2 Applicable Law Disclosures. In the event that a transferee is requested or required (by oral questions, interrogatories, requests for information or documents in legal proceedings, or by the Securities and Exchange Commission, subpoena, civil investigative demand or other similar process) to disclose any Confidential Information, the transferee shall provide the transferor with prompt written notice of any such request or requirement so that the transferor may seek a protective order or other appropriate remedy and/or waive compliance with the provisions of this Agreement. If, in the absence of a protective order or other remedy or the receipt of a waiver by the transferor, the transferee is nonetheless legally compelled to make any such disclosure of Confidential Information or else stand liable for contempt, the transferee may, without liability hereunder, disclose to such Person only that portion of the Confidential Information that on the advice of counsel is legally required to be disclosed, provided that the transferee uses its reasonable efforts to assist the transferor in obtaining an appropriate protective order or other reliable assurance that confidential treatment will be accorded the Confidential Information.

24.3 Ownership of Confidential Information. All Confidential Information obtained, developed or created by or for Contractor exclusively for the Project, including the drawings and specifications and any copies of Confidential Information, is the exclusive property of Owner whether delivered to Owner or not; provided, however, that Contractor may also use such Confidential Information for internal purposes. No right or license is granted to Contractor or any third-party respecting the use of such Confidential Information by virtue of this Agreement, except to the extent required for Contractor’s performance of its obligations hereunder. Contractor shall deliver all Owner’s Confidential Information, including all copies thereof, to Owner upon request; provided, however, that Contractor may keep one copy for archival purposes only, which copy shall remain subject to the obligations of this Article 24.

24.4 Remedies. Contractor and Owner each recognize and acknowledge the competitive and confidential nature of the Confidential Information and each agrees that irreparable damage may result to the other Party if Confidential Information of such other Party is disclosed to any third party except as herein permitted or is used for any purpose other than the purposes of this Agreement. The Parties agree that money damages may not be a sufficient remedy for any breach of this Article 24. Accordingly, the Parties agree that a Party whose Confidential Information is disclosed to a third party in breach of this Article 24 shall be entitled to an injunction or injunctions (without the posting of any bond and without proof of actual damages) to prevent breaches or threatened breaches of this Article 24, and to specific

EXECUTION COPY

102

performance of this Article 24, and that neither the other Party nor its Affiliates will oppose the granting of such relief. Such remedies shall not be deemed to be the exclusive remedies for a breach of this Article 24, but shall be in addition to all other remedies available at law or equity.

24.5 Exclusions. For purposes of determining liability under this Article 24, Confidential Information shall not include: (i) information that is publicly available through no fault of the receiving Party; or (ii) acquired by the receiving Party from a source having no direct or indirect obligation of confidentiality to the disclosing Party regarding such information; provided that Contractor nonetheless continues to treat such information as Confidential Information pursuant to this Article 24.

25. INVENTIONS AND LICENSES

25.1 Invention, License. Any idea, invention, work of authorship, drawing, design, formula, algorithm, utility, tool, pattern, compilation, program, device, method, technique, process, improvement, development or discovery (collectively, “Invention”), whether or not patentable, or copyrightable, or entitled to legal protection as a trade secret or otherwise, that Contractor may conceive, make, develop, create, reduce to practice, or work on, in whole or in part, in the course of performing the Work shall be owned and retained by Contractor. Contractor hereby grants to Owner an irrevocable, nonexclusive royalty-free license (which license is freely assignable (a) to any Financing Entity or any assignee of such Financing Entity; and (b) to any party to which the Project is sold or otherwise transferred) to use all Inventions, other proprietary rights and specialized knowledge of Contractor which, in each case, form a part of the Work for Owner’s use to the extent reasonably necessary for the operation, maintenance, repair, or alteration of the Project or any subsystem or components thereof in connection with the Project or to the extent such Inventions are related to any specific design concepts developed primarily for the Project, for the operation, maintenance, repair, or alteration of any other project developed by Owner or any Affiliate of Owner or of any subsystem or component thereof, with Owner’s or its Affiliate’s exercise of such license to be at Owner’s and its Affiliate’s sole risk and expense and subject to the rights of third-parties. Contractor shall, prior to directing any Subcontractor to produce any design or engineering work in connection with the Project, obtain a valid written license of any such inventions, specialized knowledge or other proprietary property from such Subcontractor in terms substantially similar to those that obligate Contractor to Owner as expressed in this Section 25.1. Without diminishing the rights granted in the previous sentence, Contractor also acknowledges and agrees that it shall not be deemed a breach of the license granted in this Section 25.1 for any Affiliate of Owner wholly-owned by Owner’s direct or indirect corporate parent to utilize as reference material any such Invention, proprietary right or specialized knowledge. Contractor shall promptly notify Owner of any such Invention or discovery. All Contractor Deliverables and computer software prepared by Contractor pursuant to this Agreement are instruments of service in respect to the Project. They are not intended or represented to be suitable for reuse by Owner or others on extensions of the Project or on any other project. Any reuse without prior written verification or adaptation by Contractor for the specific purpose intended will be at Owner’s sole risk and without liability or legal exposure to Contractor. Owner shall defend, indemnify, and hold harmless Contractor against all Losses arising out of or resulting from such reuse. Contractor shall, at Owner’s expense and request, execute or cause the execution of any documentation reasonably requested by Owner in order to

EXECUTION COPY

103

effectuate the foregoing. Except as specifically stated herein, no other license in such patents and proprietary information is granted pursuant to this Agreement.

25.2 Contractor Deliverables. Subject to Section 25.1, the Contractor Deliverables accumulated or developed by Contractor or its employees, to the extent Owner may determine, shall become the property of Owner without any further consideration to be provided therefore, when prepared or in process, whether or not delivered by Contractor. Contractor shall deliver the Contractor Deliverables to Owner upon its request upon any termination of this Agreement, or completion of the Work.

25.3 Software Licenses. To the extent Contractor purchases any software which software is necessary or otherwise desirable for the continued operation of the Project after Substantial Completion, Contractor shall register Owner as the licensee of such software with the applicable Supplier.

25.4 Warranty. Contractor expressly warrants that there has been, and covenants that there will be, no violation, misappropriation or infringement of any trade secret, patent, trademark, copyright, or other third-party property right (including any violation of a third-party license) in any way connected with or arising out of performing the work specified in this Agreement.

25.5 Subcontractors. Notwithstanding anything to the contrary in the foregoing, Contractor and Owner acknowledge and agree that, despite Contractor’s commercially reasonable efforts to satisfy the requirements of Section 25.1 with respect to obtaining licenses of intellectual property from certain Subcontractors, certain of the subcontracts include provisions that licenses of intellectual property provided by the applicable Subcontractor are granted with respect to use on or in connection with the Project and not in connection with any other project of Owner, and that Owner’s ability to use such intellectual property in altering the Project or any other project of Owner may be restricted or prohibited. Contractor shall provide Owner a list of subcontracts with such restrictions or limitations.

26. ASSIGNMENT BY OWNER

26.1 Assignment.

26.1.1 Assignment to Financing Entities. Owner may, without Contractor’s prior consent but upon five (5) days prior Notice to Contractor, make a collateral assignment of all or part of its right, title, and interest in this Agreement to any Financing Entity. Any such Financing Entity may further sub-assign all or any portion of Owner’s rights and obligations hereunder to Owner or any Affiliate of Owner in connection with any financing or refinancing related to the development, construction, operation and maintenance of the Project. Contractor acknowledges that the Financing Parties may under certain circumstances assume the interests and rights of Owner under the Contract Documents, and that the Financing Parties may under certain circumstances foreclose upon and sell, or cause Owner to sell or lease the Project and cause any new lessee or purchaser of the Project to assume all of the interests, rights and obligations of Owner arising under the Contract Documents. In such event, Contractor hereby agrees to the assignment by Owner and the Financing Parties of the Contract Documents and its

EXECUTION COPY

104

rights herein to such purchaser or lessee. Contractor agrees that, upon receipt of written notice of such permitted assignment, it shall deliver all documents, data, Notices, and other communications required to be delivered to Owner hereunder to Owner and to the Financing Entities or to any other permitted assignee at such address as such Persons shall designate to Contractor in writing.

26.1.2 Assignment to an Affiliate of Owner. Owner may, without Contractor’s prior consent but upon five (5) days prior Notice to Contractor, assign all or part of Owner’s right, title, obligations and interest in this Agreement to any Affiliate of Owner (for purposes of this Section 26.1.2 only, the reference to “twenty percent (20%)” in the last sentence of the definition of Affiliate shall be replaced with “fifty percent (50%)”) if performance security for such Affiliate’s obligations is provided in accordance with any of subsections (a), (b), (c) or (d) in this Section 26.1.2 below. Owner’s Notice shall provide reasonable supporting documentation and financial calculations reasonably demonstrating that the relevant conditions set forth in either subsection (a), (b), (c) or (d) of this Section 26.1.2 are satisfied.

(a) Such Affiliate has a Tangible Net Worth of at least Two Hundred Million Dollars ($200,000,000) (the “Minimum Tangible Net Worth”) and a credit rating equal to or greater than the Threshold Rating; provided, however, if such Affiliate’s Tangible Net Worth declines by more than thirty percent (30%) of the Minimum Tangible Net Worth or its credit rating falls below the Threshold Rating, such Affiliate shall provide, or cause to be provided, either: (i) a letter of credit, bond or other form of security from a financial institution reasonably acceptable to Contractor, securing its obligations under this Agreement in an amount equal to the Guaranteed Amount; or (ii) a guaranty from an entity having an equivalent or higher credit rating than the Threshold Rating, guaranteeing such Affiliate’s obligations under this Agreement in an amount equal to the Guaranteed Amount.

(b) Such Affiliate has written commitments from lenders or equity investors (where the lead lender or investor has an equivalent or higher credit rating than the Threshold Rating) to provide financing for the Project in an amount equal to no less than the portion of the Separated Contract Price then remaining to be paid, and all conditions precedent to such commitments (except such assignment) have been met to close financing and fund the Project.

(c) Such Affiliate causes to be provided a letter of credit in support of its obligations under this Agreement from a bank that has senior unsecured debt rated at least A- by Standard & Poors or A3 by ▇▇▇▇▇’▇ (or an equivalent rating from a similar rating agency), and such letter of credit: (i) names Contractor as the stated beneficiary, and (ii) has a stated amount at least equal to the sum of the Guaranteed Amount.

(d) If (i) the Owner’s Parent Guaranty remains in effect, or (ii) Owner provides a guarantee of such Affiliate’s obligations under this Agreement from an entity having an equivalent or higher credit rating than the Threshold Rating, in form and substance reasonably acceptable to Contractor as set forth in Exhibit Z-2, and in an amount equal to the Guaranteed Amount. In the event that the guarantee provided by Owner pursuant to this Section 26.1.2(d) lapses or terminates, such Affiliate shall provide, within twenty (20) days of Notice of such lapse or termination from Contractor, a substitute guarantee in form and substance reasonably acceptable to Contractor as set forth in Exhibit Z-2 of assignee’s obligations under this

EXECUTION COPY

105

Agreement in an amount equal to the Guaranteed Amount from an entity having an equivalent or higher credit rating than the Threshold Rating.

Upon the assignment of Owner’s rights and obligations hereunder to any Affiliate pursuant to subsections (a), (b), (c) or (d) of this Section 26.1.2, and such Affiliate’s assumption in writing of such rights and obligations, (1) Owner shall be deemed released from and shall have no further rights, obligations, responsibilities or liabilities under this Agreement, (2) in the case of subsections (a), (b), (c) and (d)(ii) of this Section 26.1.2, Owner’s Parent Guaranty shall be released in its entirety, and (3) Owner shall remain responsible for all liabilities relating to matters occurring prior to such assignment, except to the extent such Affiliate agrees in writing to be responsible for such liabilities.

26.1.3 Assignment to Other Persons. In addition, Owner may assign all or part of its right, title, obligations and interest in this Agreement to any other Person with the prior written approval of Contractor, which approval shall not be unreasonably withheld or delayed. As a condition to any such assignment, Contractor in its sole discretion may require that the prospective assignee provide performance security for such assignee’s obligations hereunder as follows. Owner shall provide Contractor with a written request for approval, together with reasonable supporting documentation and financial calculations reasonably demonstrating that, if Owner proposes to assign all or any part of its right, title, obligations and interest in this Agreement to an assignee pursuant to subsections (a), (b), (c) or (d) of this Section 26.1.3, the relevant conditions are satisfied. If the required conditions of any one of subsection (a), (b), (c) or (d) of this Section 26.1.3 are satisfied, Contractor shall not be entitled to withhold its approval of such assignment on the basis of insufficient payment and performance security.

(a) If any proposed assignee has a Tangible Net Worth (calculated in accordance with generally accepted accounting principles) of at least the Minimum Tangible Net Worth and a credit rating equal to or greater than the Threshold Rating, Contractor may not require any performance security for Owner’s obligations from such prospective assignee upon such Person’s assumption of this Agreement; provided, however, if such assignee’s Tangible Net Worth declines by more than thirty percent (30%) of the Minimum Tangible Net Worth or its credit rating falls below the Threshold Rating, such assignee shall provide, or cause to be provided, either: (i) a letter of credit, bond or other form of security from a financial institution reasonably acceptable to Contractor, securing assignee’s obligations under this Agreement in an amount equal to the Guaranteed Amount, or (ii) a guaranty from an entity having an equivalent or higher credit rating than the Threshold Rating, guaranteeing assignee’s obligations under this Agreement in an amount equal to the Guaranteed Amount.

(b) If any proposed assignee has written commitments from lenders or equity investors (where the lead lender or investor has an equivalent or higher credit rating than the Threshold Rating) to provide financing for the Project in an amount equal to no less than the portion of the Separated Contract Price then remaining to be paid, and all conditions precedent to such commitments (except such assignment) have been met to close financing and fund the Project, Contractor may not require any performance security for Owner’s obligations from such prospective assignee upon such Person’s assumption of this Agreement.

(c) If any proposed assignee causes to be provided a letter of credit in support of such assignee’s obligations under this Agreement from a bank that has senior unsecured debt rated at least A- by Standard & Poors or A3 by ▇▇▇▇▇’▇ (or an equivalent rating from a similar rating agency), and such letter of credit: (i) names Contractor as the stated beneficiary, and (ii) has a stated amount at least equal to the sum of the Guaranteed Amount, Contractor may not require further performance security from any prospective assignee.

(d) If (iii) the Owner’s Parent Guaranty remains in effect, or (iv) Owner provides a guarantee of such assignee’s obligations under this Agreement from an entity having an equivalent or higher credit rating than the Threshold Rating, in form and substance reasonably acceptable to Contractor as set forth in Exhibit Z-2, and in an amount equal to the Guaranteed Amount, Contractor may not require any performance security for Owner’s obligations from such prospective assignee upon such Person’s assumption of this Agreement. In the event that the guarantee provided by Owner pursuant to this Section 26.1.3(d) lapses or terminates, assignee shall provide, within twenty (20) days of Notice of such lapse or termination from Contractor, a substitute guarantee in form and substance reasonably acceptable to Contractor as set forth in Exhibit Z-2 of assignee’s obligations under this Agreement in an amount equal to the Guaranteed Amount from an entity having an equivalent or higher credit rating than the Threshold Rating.

Upon the assignment of Owner’s rights and obligations as approved by Contractor under the first paragraph of this Section 26.1.3, and such permitted assignee’s assumption in writing in of such rights and obligations, (1) Owner shall be deemed released from and shall have no further rights, obligations, responsibilities or liabilities under this Agreement, (2) in the case of subsection (a), (b), (c) and (d)(ii) of this Section 26.1.3, Owner’s Parent Guaranty shall be released in its entirety, and (3) Owner shall remain responsible for all liabilities relating to matters occurring prior to such assignment, except to the extent such permitted assignee agrees in writing to be responsible for such liabilities.

26.1.4 Assignment in Violation. Any attempted assignment or delegation in violation of this Section 26.1 shall be null and void and shall be ineffective to relieve Owner of its obligations hereunder.

26.1.5 Owner Indemnitee to Include Successors and Assigns. Upon any assignment by Owner hereunder, the definition of “Owner Indemnitee” shall be deemed modified to include the assignor and permitted assignee under such assignment and each of their respective employees, agents, partners, Affiliates, shareholders, directors, officers, successors and assigns.

26.2 Transfer of Work; Third-Party Beneficiaries. Owner may, upon reasonable advance written notice to Contractor not to be less than five (5) Business days, assign, convey or transfer all or part of its right, title, and interest in the Work to any Affiliate of Owner (whether or not such Affiliate provides consideration to Owner for such assignment, conveyance or transfer). Each such Affiliate-assignee shall be deemed to be a third-party beneficiary of the following provisions of this Agreement: Article 17, but only to the extent any portion of the Work is assigned, conveyed or transferred to such Affiliate assignee, Article 23, but only to the extent any portion of the Work is assigned, conveyed or transferred to such Affiliate-assignee,

EXECUTION COPY

107

and Article 29. Owner shall have the right to enforce any provisions of this Agreement with respect to any Work assigned, conveyed or transferred to an Affiliate (including any warranties, indemnities or rights to receive liquidated damages with respect to such Work) and such assignment, conveyance or transfer shall not affect Owner’s rights hereunder with respect to any Work.

27. ASSIGNMENT BY CONTRACTOR

Contractor understands that this Agreement is personal to Contractor. Contractor shall have no right, power, or authority to assign or delegate this Agreement or any portion thereof, either voluntarily or involuntarily, or by operation of law. Absent Owner’s prior written approval, Contractor’s attempted assignment or delegation of any of its Work hereunder shall be null and void and shall be ineffective to relieve Contractor of its responsibility for the Work assigned or delegated. Nothing herein shall be deemed to limit the right of Contractor to subcontract out portions of this Work to others in accordance with the other terms and conditions of this Agreement.

28. HAZARDOUS MATERIALS

28.1 Use by Contractor. Contractor shall not and shall not permit any of its Subcontractors, directly or indirectly to, permit the manufacture, storage, transmission or presence of any Hazardous Materials on the Site, and shall not and shall not permit any of its Subcontractors to release, discharge or otherwise dispose of any Hazardous Materials on the Site, in each case except in accordance with Applicable Laws.

28.2 Remediation by Contractor. Without limiting what may constitute a “Change In Law” hereunder, Contractor shall conduct and complete all investigations, studies, sampling, testing and remediation of the Site in connection with the potential release, discharge or presence of Hazardous Materials brought onto or generated at the Site by Contractor or any Subcontractor or any third-party (other than Owner, except to the extent that such Hazardous Materials were brought onto or generated at the Site and delivered to Contractor or any Subcontractor to be handled by the same in the course of performing the Work) to the extent required under any Applicable Laws. Contractor shall promptly comply with all lawful orders and directives of all Governmental Authorities regarding Applicable Laws relating to the use, transportation, storage, handling, presence, or release by Contractor, any Subcontractor or any Person acting on its or their behalf or under its or their control of any Hazardous Materials brought onto or generated at the Site by Contractor or any Subcontractor, except to the extent any such orders or directives are being contested in good faith by appropriate proceedings in connection with the Work.

28.3 Notice of Hazardous Materials. If Contractor discovers, encounters or is notified of the existence of any contaminated materials or Hazardous Materials at the Site:

(a) Contractor shall promptly notify Owner thereof and restrict access to the area containing such contaminated materials or Hazardous Materials;

(b) if Contractor or any Subcontractor has brought such Hazardous Materials onto the Site or generated such Hazardous Materials, Contractor shall promptly remove such Hazardous Materials from the Site and remediate the Site in accordance with all Applicable

EXECUTION COPY

108

Laws and Applicable Permits (including Contractor’s EPA Hazardous Material Disposal Permit) and at Contractor’s sole cost and expense; and

(c) if Contractor or any Subcontractor has brought such Hazardous Materials onto the Site or generated such Hazardous Materials, Contractor shall not be entitled to any extension of time or additional compensation hereunder for any delay or costs incurred by Contractor as a result of the existence of such Hazardous Materials.

28.4 Suspension and Mitigation. Contractor shall suspend the Work if required by Owner in accordance with Section 20.4. Contractor shall use reasonable efforts consistent with the requirements of Applicable Law or the health and safety of persons or property to mitigate the effects of such suspension and the amount of Work so suspended.

28.5 Pre-Existing Contamination. Owner shall advise Contractor of any known material “pre-existing contamination.” For purposes of this section, “pre-existing contamination” means any Hazardous Materials present at the Site or Ancillary Site that were not brought to the Site or Ancillary Site by Contractor or its Subcontractors. Upon notice from Contractor, Owner shall, at Owner’s sole expense and risk, determine the appropriate action to be taken with respect to such pre-existing contamination, including, as Owner determines is necessary, arranging for the handling, storage, transportation, treatment or delivery for disposal of such pre-existing contamination. In the event Contractor executes or completes (with the concurrence of the Owner’s Representative) any required governmental forms relating to regulated activities, including any storage, treatment, transportation, handling or disposal of Hazardous Materials, Contractor shall be acting as, and be deemed to have acted as, Owner’s agent.

28.6 Handling Pre-Existing Contamination as part of the Work. Notwithstanding anything to the contrary herein, in the event that Contractor agrees to remediate or otherwise handle any pre-existing contamination as part of the Work, such remediation or handling shall be performed by specialty Subcontractors, Sections 28.4 or 28.5 shall not apply, and Contractor shall be responsible for such pre-existing contamination as though such materials were brought onto the Site or generated by Contractor or a Subcontractor; provided that Contractor’s liabilities arising out of such pre-existing contamination shall not exceed the liability assumed by such specialty Subcontractor under the terms and conditions of its subcontract with Contractor for such Work. Notwithstanding anything to the contrary herein, Owner shall have the right to review and approve any such subcontract before Contractor enters into such subcontract, such approval not to be unreasonably delayed.

29. NON-PAYMENT CLAIMS

To the extent payment by Owner has been made in accordance with Article 6: (a) Contractor shall not directly or indirectly create, incur, assume or suffer to be created by it or any Subcontractor, employee, laborer, materialman or other supplier of goods or services any right of retention, mortgage, pledge, assessment, security interest, lease, advance claim, levy, claim, lien, charge or encumbrance on the Work, the Site, the Project or any part thereof or interest therein (each a “Contractor Lien”); (b) Contractor shall keep the Site, the Work, the Equipment and Materials, including the Owner Furnished Equipment, the Leased Equipment

EXECUTION COPY

109

and all Subcontractor equipment and materials free of Contractor Liens; and (c) Contractor shall promptly pay or discharge, and discharge of record, any such Contractor Lien or other charges which, if unpaid, might be or become a Contractor Lien. Contractor shall notify Owner as soon as practicable of the assertion of any Contractor Lien. If any Owner Indemnitee becomes aware of any Contractor Lien, such Owner Indemnitee may so notify Contractor in writing, and Contractor, to the extent payment by Owner has been made in accordance with Article 6, shall then: (x) satisfy and obtain the release of such Contractor Lien; or (y) defend Owner Indemnitees against any such Contractor Lien, provide assurances of payment as described in the last sentence of this Article 29 and obtain the release of such Contractor Lien. If Contractor does not promptly, and in any event within fifteen (15) days after such Notice, satisfy such Contractor Lien, give such Owner Indemnitee reasons in writing that are satisfactory to such Owner Indemnitee for not causing the release of such Contractor Lien, or contest such Contractor Lien in accordance with the provisions of the last sentence of this Article 29, then any Owner Indemnitee shall have the right, at its option, after written notification to Contractor, and subject to Applicable Law, to cause the release of, pay, or settle such Contractor Lien, and Owner at its sole option may: (1) require Contractor to pay, within five (5) days after request by Owner; (2) draw on the Letter of Credit; or (3) withhold, in addition to the Retainage, other amounts due or to become due to Contractor (in which case Owner shall, if it is not the applicable Owner Indemnitee, pay such amounts directly to Owner Indemnitee causing the release, payment, or settlement of such liens or claims), all costs and expenses incurred by Owner Indemnitee in causing the release of, paying, or settling such Contractor Lien, including administrative costs, attorneys’ fees, and other expenses. Contractor shall have the right to contest any such Contractor Lien, provided it first provides to Owner a bond or other assurances of payment reasonably satisfactory to Owner in the amount of such Contractor Lien and in form and substance reasonably satisfactory to Owner.

30. NOTICES AND COMMUNICATIONS

30.1 Requirements. Any Notice pursuant to the terms and conditions of this Agreement shall be in writing and: (a) delivered personally; (b) sent by certified mail, return receipt requested; (c) sent by a recognized overnight mail or courier service, with delivery receipt requested; or (d) sent by confirmed facsimile transmission or electronic mail, with telephonic confirmation, to the following addresses:

31.2 Limitations on Contractor’s Liability.

31.2.1 Maximum Liability Amount. Prior to Substantial Completion of a Unit, Contractor’s and its Subcontractors’ liability for claims by Owner arising out of or relating to the performance or non-performance of obligations or the Work with respect to such Unit shall in no event be greater in the aggregate than an amount equal to *** percent (***%) of the Separated Contract Price related to such Unit; provided that Contractor’s liability for the Owner Furnished Equipment included in a Unit, howsoever arising, including the impacts on Contractor of any failures or deficiencies in the performance and warranties of, or delays, to the extent attributable in any way to the Owner Furnished Equipment, liquidated damages related thereto, and any failure or default by the Upgrade Suppliers to perform with respect to such Unit in accordance with the terms of the Upgrade Contracts to the extent such failure or default adversely affects the Contractor, shall not exceed *** Dollars ($***) per Unit. Following the Substantial Completion Date of a Unit, Contractor’s and its Subcontractor’s liability, howsoever caused, for claims by Owner arising out of or relating to the performance or non-performance of obligations or the Work, including claims for payment of Performance Liquidated Damages and Delay Liquidated Damages, with respect to such Unit shall in no event be greater than an amount equal to *** percent (***%) of the portion of the Separated Contract Price related to such Unit; provided that Contractor’s liability for the Owner Furnished Equipment included in a Unit, howsoever arising, including the impacts on Contractor of any failures or deficiencies in the performance and warranties of, or delays, to the extent attributable in any way to the Owner Furnished Equipment, liquidated damages related thereto, and any failure or default by the Upgrade Suppliers to perform with respect to such Unit in accordance with the terms of the Upgrade Contracts to the extent such failure or default adversely affects the Contractor, shall not exceed *** Dollars ($***) per Unit. Notwithstanding anything to the contrary in the foregoing, nothing contained in this Section 31.2.1 shall be construed to limit Contractor’s liability (a) with respect to any of its indemnity obligations under Article 23, or (b) with respect to any willful misconduct or fraud on the part of Contractor’s senior supervisory personnel at the Project Director level or above.

31.2.2 Maximum Liquidated Damages. In no event shall Contractor’s aggregate liability (a) under Section 15.1 for Delay Liquidated Damages exceed *** percent (***%) of the portion of the Separated Contract Price applicable to the Unit to which such Delay Liquidated Damages relate; (b) under Section 15.3 for Performance Liquidated Damages exceed *** percent (***%) of the portion of the Separated Contract Price applicable to the Unit to which such Performance Liquidated Damages relate; and (c) in the aggregate under Sections 15.1 and 15.3 exceed *** percent (***%) in the aggregate of the portion of the Separated Contract Price applicable to the Unit to which such liquidated damages relate. Notwithstanding any of the foregoing provisions of this Section 31.2.2, the limitations of this Section 31.2.2 shall not limit Owner’s remedies for any other breach of this Agreement other than a failure of a Unit to achieve Substantial Completion on or before the Substantial Completion Guaranteed Date for such Unit or the failure of a Unit to satisfy the Performance Guarantees.

31.2.3 Calculation of Liability. Notwithstanding anything herein to the contrary, for purposes of determining whether the maximum liability amounts provided in Section 31.2.1 have been exceeded, the following items shall be excluded from the calculation of any such maximum liability amount: (a) amounts expended to achieve Mechanical Completion, the Environmental Compliance Guarantees and the Minimum Performance Criteria (except, in each case, with respect to the Owner Furnished Equipment for which all amounts expended shall be included in the calculation of such maximum liability amounts); (b) insurance proceeds from the OCIP policies or the Project-specific insurance policies obtained by Contractor pursuant to Article 21 (not including any proceeds from any other insurance coverage of Contractor); and (c) amounts paid by Contractor to or on behalf of Owner in respect of any damages or third-party claims (other than Owner Indemnitees and Contractor Indemnitees) arising out of the willful misconduct or fraud of Contractor’s senior supervisory personnel at the Project Director level or above. For the purposes of this Section 31.2, the Separated Contract Price shall be allocated fifty percent (50%) to ▇▇▇▇ ▇ and fifty percent (50%) to ▇▇▇▇ ▇.

31.3 Specific Performance. In addition to any other rights and remedies of Owner hereunder, as a specific performance obligation, Contractor guarantees that the Project shall as a condition to Substantial Completion, Successfully Run the Emissions Tests and achieve the Environmental Compliance Guarantees. Contractor acknowledges that Contractor’s failure to Successfully Run the Emissions Tests and achieve the Environmental Compliance Guarantees would cause Owner irreparable harm for which money damages would not constitute an adequate remedy, and therefore Contractor stipulates that specific performance is an appropriate remedy should Contractor breach such obligation.

31.4 Limitation on Owner’s Liability. In no event shall Owner’s liability pursuant to this Agreement, whether arising in contract warranty, or otherwise, be greater in the aggregate than the Separated Contract Price and any other amounts for which Owner is expressly obligated to pay Contractor pursuant hereto, less amounts previously paid by Owner; provided, however that nothing contained in this Section 31.4 or in any other provision of this Agreement shall be construed to limit Owner’s liability for: (a) its indemnity obligations pursuant to Article 23; or (b) with respect to any willful misconduct or fraud on the part of Owner’s senior supervisory personnel for the Project at an equivalent level to Project Director and above. Contractor’s sole recourse for any damages or liabilities due to Contractor by Owner pursuant to this Agreement shall be limited to the assets of Owner and to the parent guarantee provided by Owner hereunder without recourse individually or collectively to the assets of the members or the Affiliates of Owner, the Financing Entities or their respective officers, directors, employees or agents of Owner, its members or their Affiliates.

31.5 Releases, Indemnities and Limitations. The releases, indemnities, waivers, subrogation, assumptions of and limitations on liabilities and limitations on remedies expressed in this Agreement, subject to the terms hereof, shall apply even in the event of fault, negligence, or strict liability of the Party released or indemnified, or whose liability is limited or assumed or against whom right of subrogation are waived and shall extend to such Party’s subcontractors, and in each case to such Party’s and its subcontractors’ Affiliates, officers, directors, employees, licensees, agents or partners. If Owner is not the sole owner or operator of the Site or the Ancillary Sites, Owner shall obtain from such other owners or operators the same releases from and limitations on liabilities for Contractor’s benefit that are afforded to Contractor under this

EXECUTION COPY

113

Agreement. The Parties acknowledge and agree that this Agreement satisfies the Express Negligence Rule.

31.6 Representations and Remedies. Each Party makes no representations, covenants, warranties, or guarantees, express or implied, other than those expressly set forth herein and in the Exhibits hereto.

31.7 Limitation on Remedies. It is the intent of Owner and Contractor that the provisions of this Agreement state all of the rights and remedies of the Parties with respect to this Agreement, and are the sole or exclusive (or words of similar import) rights or remedies for the failure to satisfy the applicable obligation arising hereunder. The Parties’ rights, liabilities, responsibilities and remedies as stated herein with respect to this Agreement and the Work shall be the sole and exclusive remedies of the Parties for failure to satisfy such obligations, notwithstanding any right or remedy otherwise available at law or in equity. For purposes of clarity, the foregoing shall not be construed to limit a Party’s right to exercise its dispute resolution rights under Article 32 at any time during the term of this Agreement.

32. DISPUTES

32.1 Negotiations. Subject to Section 32.2, any disputes arising under this Agreement shall first be referred to Owner’s Project Representative and the Project Director. Any dispute that cannot be resolved between Owner’s Project Representative and the Project Director within fourteen (14) days, or in the case of payment disputes five (5) days, after receipt by each thereof of Notice of such dispute (specifically referencing this Section 32.1) shall be referred, by Notice setting forth, in reasonable detail, the basis of the dispute and signed by Owner’s Project Representative and the Project Director, to the executive officers of the Parties designated by them as their designated representatives (which shall not be Owner’s Project Representative or the Project Director) for resolution. If the Parties, negotiating in good faith, fail to reach an agreement within a reasonable period of time, not exceeding twenty (20) days or, in the case of payment disputes, ten (10) days after such referral, then either Owner or Contractor may, if the dispute is in regards to an issue subject to Section 32.2, notify the other of its desire to engage an Independent Expert in accordance with Section 32.2, or may bring a suit, claim or cause of action in any state or federal court of law to protect its rights and interest hereunder in accordance with the terms of Section 33.2 hereof.

32.2 Disputed Invoice Payments and Changes In Work. In the case of a dispute with respect to technical engineering, procurement or construction issues regarding whether a Change In Work has occurred or Contractor has achieved a payment milestone satisfying such condition to an Invoice Payment, that is not resolved by the management negotiation procedure described in Section 32.1, upon determining to select an Independent Expert to resolve such dispute, the Party electing to utilize the Independent Expert shall notify the other Party in writing, nominating five (5) Independent Experts for the other Party’s review. The other Party shall promptly, and in any event within ten (10) days notify the nominating Party whether any of the nominated experts are acceptable, and if not, shall nominate five (5) Independent Experts for the original nominating Party’s consideration. If the Parties are unable to agree upon an Independent Expert within thirty (30) days, either Party may bring a suit, claim or cause of action in any state or federal court of law. Any decision or award made by the Independent Expert shall be limited

114

in scope to the direct issue regarding the disputed Change In Work or Milestone Payment and shall be binding on both Parties.

32.3 Work to Continue. Unless otherwise agreed in writing, Contractor shall diligently carry on the Work during the pendency of any disputes so long as all undisputed amounts payable to Contractor hereunder have been paid.

33. MISCELLANEOUS

33.1 Severability. The invalidity or unenforceability of any portion or provision of this Agreement shall in no way affect the validity or enforceability of any other portion or provision hereof. Any invalid or unenforceable portion or provision shall be deemed severed from this Agreement and the balance of this Agreement shall be construed and enforced as if this Agreement did not contain such invalid or unenforceable portion or provision. If any such provision of this Agreement is so declared invalid, the Parties shall promptly negotiate in good faith new provisions to eliminate such invalidity and to restore this Agreement as near as possible to its original intent and effect.

33.2 Governing Law; Consent to Jurisdiction and Venue. This Agreement shall be governed by the internal laws of the State of Texas, excluding its conflict of laws provisions. EXCEPT AS OTHERWISE PROVIDED IN THIS AGREEMENT, AND TO THE EXTENT PERMITTED BY LAW, THE PARTIES HERETO AGREE THAT ALL ACTIONS OR PROCEEDINGS ARISING IN CONNECTION WITH THIS AGREEMENT, SHALL BE TRIED AND LITIGATED ONLY IN THE STATE AND FEDERAL COURTS LOCATED IN THE COUNTY OF DALLAS, STATE OF TEXAS. THE PARTIES, TO THE EXTENT THEY MAY LEGALLY DO SO, WAIVE ANY RIGHT EACH MAY HAVE TO ASSERT THE DOCTRINE OF FORUMNONCONVENIENS OR TO OBJECT TO VENUE TO THE EXTENT ANY PROCEEDING IS BROUGHT IN ACCORDANCE WITH THIS SECTION AND STIPULATE THAT THE STATE AND FEDERAL COURTS LOCATED IN THE COUNTY OF DALLAS, STATE OF TEXAS SHALL HAVE INPERSONAM JURISDICTION AND VENUE OVER SUCH PARTY FOR THE PURPOSE OF LITIGATING ANY SUCH DISPUTE, CONTROVERSY, OR PROCEEDING ARISING OUT OF RELATED TO THIS AGREEMENT. THE PARTIES ACKNOWLEDGE AND AGREE THE TERMS AND CONDITIONS OF THIS AGREEMENT HAVE BEEN FREELY, FAIRLY AND THOROUGHLY NEGOTIATED. FURTHER, THE PARTIES ACKNOWLEDGE AND AGREE SUCH TERMS AND CONDITIONS, INCLUDING THOSE RELATING TO WAIVERS, ALLOCATIONS OF, RELEASES FROM, INDEMNITIES AGAINST AND LIMITATIONS OF LIABILITY, WHICH MAY REQUIRE CONSPICUOUS IDENTIFICATION, HAVE NOT BEEN SO IDENTIFIED BY MUTUAL AGREEMENT AND THE PARTIES HAVE ACTUAL KNOWLEDGE OF THE INTENT AND EFFECT OF SUCH TERMS AND CONDITIONS.

33.3 Survival of Termination. The provisions of this Agreement which by their nature are intended to survive the termination, cancellation, completion or expiration of this Agreement including any express limitations of or releases from liability shall continue as a valid and enforceable obligation of the Party notwithstanding any such termination, cancellation, completion or expiration.

115

33.4 No Oral Modification. No oral or written amendment or modification of this Agreement (including a Change In Work Form accepted under Article 16) by any officer, agent, or employee of Contractor or Owner, either before or after execution of this Agreement, shall be of any force or effect unless such amendment or modification is in writing and is signed by a duly authorized representative of the Party to be bound thereby.

33.5 No Waiver. A Party’s waiver of any breach or failure to enforce any of the terms, covenants, conditions, or other provisions of this Agreement at any time shall not in any way affect, limit, modify, or waive that Party’s right thereafter to enforce or compel strict compliance with every term, covenant, condition, or other provision hereof, any course of dealing or custom of the trade notwithstanding. All waivers must be in writing and signed on behalf of Owner and Contractor in accordance with Section 33.4. Contractor and Owner each represents and warrants to its knowledge that as of the date hereof the other Party isnot in breach or default of its obligations under this Agreement, and that Contractor and Owner, respectively, has no known unresolved claims against the other Party, nor has reason to make any claim not heretofore asserted and delivered by official Notice based on facts known as of this date.

33.6 Review and Approval. Notwithstanding Owner’s or the Financing Entities’, if any, review or Owner’s approval of any items submitted to Owner or the Financing Entities for review or approval, neither Owner nor the Financing Entities, if any, or any of their representatives or agents reviewing such items, including the Owner’s Engineer, shall have any liability for, under or in connection with the items such Person reviews or approves and Contractor shall remain responsible for the quality and performance of the Work. Neither Owner’s nor the Financing Entities’ review or approval of any items, including the Submittals, shall constitute a waiver of any claim or right that Owner may then or thereafter have against Contractor. Unless otherwise expressly provided herein, Owner shall not unreasonably delay its review of any item submitted by Contractor for review or approval. Any inspection comment, review or approval of any Contractor Deliverable shall be performed in Owner’s sole discretion. The review or approval by Owner of any Subcontractor shall not constitute any approval of the Work undertaken by any such Person, cause Owner to have any responsibility for the actions, the Work, or payment of such Person or to be deemed to be in an employer-employee relationship with any such Subcontractor, or in any way relieve Contractor of its responsibilities and obligations under this Agreement.

33.7 Time. Subject to the terms and conditions of this Agreement, including the express provisions providing for adjustment of the Substantial Completion Guaranteed Dates and the provisions limiting Contractor’s liability for its failure to achieve Substantial Completion by the Substantial Completion Guaranteed Date, Contractor acknowledges that timely achievement of Substantial Completion by the Substantial Completion Guaranteed Date is essential to Owner, and therefore TIME IS OF THE ESSENCE with respect to meeting the Substantial Completion Guaranteed Date; provided that Owner’s sole and exclusive remedies for delays in performance of the Work shall be as set forth in Sections 15.1, 15.6 and 19.1(g).

33.8 Third Party Beneficiaries. The provisions of this Agreement are intended for the sole benefit of Owner and Contractor and there are no third-party beneficiaries hereof, except the Financing Entities where expressly provided and assignees as contemplated by the terms of Article 26.

In connection therewith, Contractor shall: (x) execute any assignments, amendments and modifications hereto reasonably requested by the Financing Entities; provided that any such amendments or modifications to this Agreement are of a nature customarily obtained by financing parties for projects similar to the Project and do not alter the timeframes stated herein if altering such timeframes would adversely impact performance of the Work, or materially affect the obligations, benefits, risk or liability of Contractor arising out of the Agreement or the Separated Contract Price or proposed bonuses; (y) promptly execute or consent to other documents to the extent reasonably required by the Financing Entities, which consents may, among other things, include provisions whereby Contractor agrees to: (i) provide such Financing Entities reasonable notice of and opportunity to cure Owner’s defaults hereunder; (ii) allow such Financing Entities (as security for Owner’s financing) to be assigned all of Owner’s rights hereunder and in such assets in the event of an Owner’s Event of Default; provided, however, that Owner shall keep Contractor currently informed of such assignment or reassignment; (iii) provide for other customary investor or lender protection provisions that are not in violation of Applicable Law; and (iv) provide copies of any Certificate of Substantial Completion, Notice of Non-Critical Deficiencies, or any other certificates, Notices and any documents and plans submitted to Owner for review or approval hereunder, to the Financing Entities and their designated agents or representatives; and (z) deliver customary legal opinions of counsel to Contractor in accordance with Section 33.16.

Contractor shall respond promptly to requests for information regarding the qualifications, experience, past performance and financial condition of Contractor and other matters pertaining to Contractor’s obligations hereunder.

With respect to any Change In Work which adjusts the Separated Contract Price by compensating Contractor on a reimbursable cost or time and materials basis, or with respect to Work performed by Contractor on a reimbursable cost or time and materials basis pursuant to an Owner’s Directive, Contractor shall maintain, in accordance with generally accepted accounting principles consistently applied, records and books of account.

shall be only for verification of such costs, and Contractor shall not be required to keep records of or provide access to those of its costs covered by the fee, allowances, fixed rates, unit prices, lump sum amounts, or of costs which are expressed in terms of percentages of other costs; providedfurther that Owner shall be permitted access and Contractor shall retain records and books of account for such longer period, not to exceed six (6) months, as may be required for Owner to complete an audit begun and which Owner has made reasonable efforts to complete during the initial period ending one (1) year after the Final Completion Date of the second Unit.

Such records shall be open to inspection by Owner at all reasonable times until the expiration of the audit period set forth in this Section 33.22.

Owner shall be responsible for all costs and expenses of such audit.
