Unless otherwise mutually agreed, Contractor’s Site Representative shall attend all Progress Meetings after Contractor mobilizes to the Site. In addition to the above monthly Progress Meetings, Contractor shall hold regularly scheduled (but not less frequently than weekly during construction) status or scheduling meetings with its Subcontractors as appropriate, and Owner shall have the right but not the obligation to attend and participate in such weekly status meetings; provided, that, if Contractor determines in its

reasonable discretion that Owner’s attendance at the meeting would prohibit Contractor from effectively addressing confidential or sensitive issues, Contractor shall have the right to bar Owner from all or a portion of such meetings.

3.22 Signage. Neither Contractor nor its Subcontractors shall display, install, erect or maintain any advertising or other signage at the Site without Owner’s prior written approval, other than signs and notices required by applicable Laws, related safety or work rules, site identification, or used to solicit employees for the performance of the Services.

3.23 Interference with Traffic. Contractor shall carry out the Services so as not to interfere unnecessarily or improperly with (a) Owner’s operations on the Site (after Owner has assumed custody and control of the Project) or (b) access to, use of or occupation of public or private roads, footpaths or properties in the possession of Owner or any other Person. Contractor shall communicate with, and ascertain the requirements of, all Government Authorities in relation to vehicular access to and egress from the Site and shall comply with any such requirements.

4.4 Owner Equipment. Owner shall procure and provide Owner Equipment by the dates set forth in the Schedule in order to prevent delay. Except to the extent that Contractor’s failure to perform its obligations in accordance with this Agreement hereof is the cause of such non-performance or schedule delay, any impact to Contractor from the delay (or re-sequence) in delivery or performance of Owner Equipment shall give rise to a Change.

4.5 Fuel and Utilities. Owner shall provide, at no cost to Contractor, the electrical interconnect for power export from the Facility at the interconnection points identified in Exhibit A, all electrical power necessary for construction of the Project (including back feed power) and all fuel, electricity and other utilities necessary for Commissioning and Performance Testing when requested by Contractor and as required in accordance with the Schedule.

4.7 Job Site Rules. From the Effective Date until the latest of the Substantial Completion Dates of Unit 6 and the Unit 5 Scrubber, Owner, its representatives and agents shall abide by all reasonable Site safety rules promulgated by Contractor.

4.8 Payment. Owner shall pay Contractor the Contract Price, as such price may be adjusted from time to time pursuant to the provisions of this Agreement. Owner shall make all payments promptly when due.

5.1 Quality of Equipment and Workmanship. All Equipment and workmanship shall be of the respective kinds required by this Agreement, including those required by the Specifications and Prudent Industry Practices and shall be subjected from time to time to such tests as Owner may reasonably require at the place of manufacture, fabrication or preparation, or at the Site or at such other place or places as may be mutually agreed upon by the Parties, including any place of an independent third party. Contractor shall provide such assistance, labor, stores, apparatus and instruments as are normally required for examining, measuring and testing any Equipment and Owner Equipment (other than specialty tools as listed in Owner Equipment Contracts) and workmanship, before incorporation into the Project, for testing as may be reasonably selected and required by Owner. Contractor shall remove from the Site any Equipment that is not in accordance with this Agreement.

(a) The cost of conducting any test related to the Work shall be borne by Contractor unless such test is clearly intended by or provided for in this Agreement as being the responsibility of Owner If the results of such test indicate that the Equipment or the workmanship do not conform to the requirements of this Agreement (including the Specifications and Prudent Industry Practices), the costs shall be borne solely by Contractor.

(b) If the results of any such test indicate that the applicable Equipment or workmanship do not conform to the requirements of this Agreement (including the Specifications) and Owner has reasonable grounds to suspect that any other similar Equipment or workmanship may not conform to the requirements of this Agreement (including the Specifications), Owner may require Contractor to carry out further tests, which in the reasonable opinion of Owner are necessary to verify that such other similar Equipment or workmanship conforms to the requirements of this Agreement (including the Specifications). The costs of any such tests shall be borne by Owner if such tests reveal that such Equipment and workmanship conforms to the requirements of this Agreement (including the Specifications).

5.3 Samples. At the reasonable request of Owner and at Owner’s cost, Contractor shall supply Owner with samples of Equipment (for which samples can reasonably be provided). The manufacturer’s standard samples (with relevant information) and any additional samples shall be labeled as to origin and intended use in the Project.

5.4 Inspection of Operations. Owner (and its representatives) shall at all reasonable times have access to the Site and to all workshops and places where Equipment or Owner Equipment is being manufactured, fabricated or prepared for the Project. Contractor shall provide Owner a reasonable opportunity to be present for any tests of any Equipment or Owner Equipment.

5.5 Examination of Work before Covering. No part of the Equipment or Owner Equipment, as applicable, shall be permanently covered up at the Site or put out of view without affording Owner a reasonable opportunity to examine and measure any such part of the Equipment or Owner Equipment, as applicable, which is about to be covered up or put out of view, including examining foundations before any part of the Equipment or Owner Equipment, as applicable, is placed thereon. For certain agreed parts of the Work as set forth in Exhibit A, Contractor shall give notice to Owner whenever any such part of the Equipment or Owner Equipment, as applicable, or foundations is or are ready or about to be ready for examination and Owner shall, without unreasonable delay, attend (or inform Contractor that it is unnecessary for it to attend) for the purpose of examining and measuring such part of the Equipment or Owner Equipment, as applicable, or of examining such foundations.

5.6 Uncovering and Making Openings. If, following discovery of defective workmanship or materials in any part of the Work, Owner has reasonable grounds to suspect that further parts of the Work may be similarly defective, Contractor shall, upon the reasonable request of Owner, provide Owner clear evidence that such other parts are not defective to the reasonable satisfaction of Owner or shall uncover such further parts of the Work or make further openings, in or through the same, and Contractor shall inspect and repair, if necessary, any such parts. The costs of such work carried out by Contractor under this Section shall be borne by Contractor, unless the parts of the Work so uncovered turn out to be not defective in which case Owner shall bear all such costs.

6.2 Commencement of Work for Unit 6 and the Unit 5 Scrubber. For Unit 6 and Unit 5 Scrubber, Contractor shall commence the performance of the Services with respect thereto upon the receipt of the Limited Notice to Proceed with respect to Unit 6 and Unit 5 Scrubber, or, if none is given, upon the Full Notice to Proceed with respect to Unit 6 and Unit 5 Scrubber, and continuously and diligently fulfill its obligations under this Agreement through the Warranty Period. For Unit 6 and the Unit 5 Scrubber, Contractor shall perform its obligations under this Agreement in accordance with the Contract Price for Unit 6 and the Unit 5 Scrubber as set forth on Exhibit I and with the Key Schedule Milestones set forth in Exhibit C, as such may be modified and updated from time to time in accordance with the terms of this Agreement. Contractor hereby acknowledges and agrees that a portion of the Work for the Unit 5 Scrubber and Unit 6 includes: (a) Work performed under the ***, which Work has already been paid by Owner under the ***, and (b) Work performed under Duke purchase order FHP01564, which Work has already been paid by Owner under such purchase order (but is included as part of the Contract Price).

6.3 ***. Each Party shall, in good faith, cooperate with the other and use all commercially reasonable efforts to expeditiously update, in accordance with the *** as described in Exhibit I, ***.

6.4 Finalization of Schedule. The Parties shall, in good faith, cooperate with the other and use all commercially reasonable efforts to expeditiously update, in accordance with the *** as described in Exhibit I, the Preliminary Schedule for Unit 6 and the Unit 5 Scrubber, respectively, ***. Upon the issuance of the Full Notice to Proceed for Unit 6 or the Unit 5 Scrubber, Contractor shall prepare and make available to Owner at all times at the Site, or such other location mutually agreed upon by the Parties, a current, working copy of the Schedule depicting all Key Schedule Milestones and illustrating the progress which has been made on the Work against the Schedule (in hard copy and electronic format), including critical path activities interconnected by schedule logics, for Owner’s review and comment. Unless otherwise mutually agreed upon by the Parties, Contractor shall update the working copy of the Schedule monthly and shall provide a copy to Owner at the Progress Meeting; provided, however, that no update of or revisions to the working copy of the Schedule shall be deemed to alter, revise or otherwise change any of the Guaranteed Substantial Completion Dates, the Guaranteed Final Completion Dates, the Guaranteed Tie-in Commencement Date or the Guaranteed Tie-In Completion Date, which shall only be amended by a duly executed Change Order or amendment hereto.

6.5 Enhanced Project Management System. At any time following the finalization of the Schedule, in the event that Contractor’s Monthly Progress Report indicates that Contractor is unlikely to meet either the Guaranteed Substantial Completion Date or any Key Schedule Milestone identified on Exhibit C with respect to Unit 6 or the Unit 5 Scrubber, Contractor shall promptly notify Owner in writing thereof, and the Parties shall consult in good faith as to what measures need to be undertaken to regain lost time. If Contractor’s progress on any Key Schedule Milestone set forth in the Schedule is, or forecasted to be, delayed by ninety (90) days or more as compared to the Schedule, and until Contractor’s progress on such Milestone complies with the Schedule, at the request of Owner, Contractor shall, without increase to the Contract Price, establish and submit to Owner a comprehensive acceleration plan to regain compliance with the Schedule. The Parties shall consult in good faith to determine what measures to include in such comprehensive acceleration plan. Such plan shall be subject to the approval of Owner, which approval shall not be unreasonably withheld. Following such approval by Owner, Contractor shall promptly implement such plan. Unless the underlying cause for such delay constitutes a Change, neither the preparation nor the implementation of such plan shall constitute a Change.

6.6 Unit 5 Scrubber Tie-In. Contractor shall perform Unit 5 Scrubber Tie-In in accordance with the Guaranteed Tie-In Commencement Date and Guaranteed Tie-In Completion Date, both as may be adjusted in accordance with Exhibit I. Owner shall have the right to make adjustments to such outage schedule, including delaying or accelerating the Guaranteed Tie-In Commencement Date or the Guaranteed Tie-In Completion Date; provided, that as a result of any such adjustment, Contractor shall be entitled to an equitable adjustment in the Contract Price and the Schedule in accordance with Article 8. *** (or longer if Contractor is entitled to a Change upon inspection of the tie-in ducts which reveals differing conditions) to such portion of the Site as Contractor may reasonably require to perform the Work during the outage for Unit 5 Scrubber Tie-In.

7.1 Cash Flow Plan. *** as Exhibit F-1 ***. In connection with and as part of the ***, the Contractor shall update and revise the Cash Flow Plan in accordance with Exhibit I. On or before the ***, Owner shall issue a Change Order to capture all of the updates made to the Cash Flow Plan pursuant to Exhibit I, and an updated Cash Flow Plan shall be attached to this Agreement as Exhibit F.

(i) In consideration of Contractor’s performance and provision of the Work as specified in this Agreement, Contractor shall invoice and

Owner shall pay to Contractor that portion of the Contract Price (a “Milestone Payment”) of Unit 6 or the Unit 5 Scrubber assigned to each milestone set forth in Exhibit F-1 (a “Milestone”) that Contractor completes in accordance with this Agreement. Owner and Contractor agree that each Milestone Payment is a reasonable representation of the value of the related Milestone.

(ii) Upon completion of each Milestone, irrespective of sequence, for which Contractor has not been previously paid, Contractor shall submit to Owner an invoice for the Milestone Payment with respect to such Milestone (the “Invoice”). *** Contractor shall make available such documentation and materials as Owner may reasonably require to substantiate Contractor’s right to payment of such Invoice.

(iii) If at any time the *** contained within any Monthly Progress Report indicates that the actual *** incurred by Contractor in performing the Work exceeds the *** (the amount of such excess, the “***”), then the Parties shall share in such *** as provided in Section 7.2(b) below. If, at the latest of the Final Completion of Unit 6 and the Unit 5 Scrubber, the *** contained within the final Monthly Progress Report indicates that the actual *** incurred by Contractor in performing the Work is less than the *** (the amount of such shortage, the “***”), then the Parties shall share in such *** as provided in Section 7.2(b) below.

(A) Owner shall pay *** of all *** incurred by Contractor in performing the Work until such time as the *** incurred by Contractor in performing the Work reaches the ***.

(B) At such time as *** incurred by Contractor in performing the Work reaches the ***, Owner thereafter shall pay *** of all *** incurred by Contractor in performing the Work in excess of the *** until such time as the *** portion of the *** to be borne by Contractor in performing the Work reaches the ***.

(C) At such time as the *** share of the *** to be borne by Contractor in performing the Work reaches the ***, Owner shall thereafter pay *** of all further *** incurred by Contractor thereafter in performing the Work in excess of the ***, but without contingency, fee or G&A.

(D) Notwithstanding the above or anything else in this Agreement to the contrary, the Contractor’s total liability for all *** shall be capped at the ***.

(ii) ***. If, at the latest of the Final Completion of Unit 6 and the Unit 5 Scrubber, the Craft Labor Cost Comparison contained within the final Monthly Progress Report for the Project indicates the existence of a ***, then Owner shall be required to pay to Contractor, as part of the applicable Final Payment Invoice, an amount equal to *** of such ***.

(iii) Change Orders. Concurrently with the payment by Owner of any *** payment, Owner shall issue a Change Order, and Contractor shall accept such Change Order, (a) to increase the Contract Price for Unit 6 and Unit 5 Scrubber by the amount of such payment, with such increases to be allocated proportionally between Unit 6 and the Unit 5 Scrubber in the same ratio as the craft labor hours allocable to each scope of Work, and (b) to adjust the Target Labor Cash Flow Plan set forth in Exhibit F-2 to reflect the existence of a ***. Concurrently with the payment by Owner of any *** payment, Owner shall issue a Change Order to decrease the Contract Price for Unit 6 and Unit 5 Scrubber by the amount of such payment, with such decreases to be allocated proportionally between Unit 6 and the Unit 5 Scrubber in the same ratio as the craft labor hours allocable to each scope of Work.

(c) Revisions to Cash Flow Plan. If any Monthly Progress Report shows that the amount actually paid or payable by Owner for *** incurred by Contractor in performing the Work through the end of the month for which such Monthly Progress Report relates varies by more than *** in each of two consecutive Monthly Progress Reports from the amounts scheduled to be paid for

*** during such two month period as reflected in the ***, prior to the issuance of the next Invoice, Contractor shall create a revised forecast of future payments to be made by Owner for the *** to be incurred by Contractor in performing the Work for the Project (it being understood that the intent of such revised forecast shall be to make adjustments necessary to eliminate such variance), which revised forecast shall be reasonably acceptable to Owner, and Owner shall issue a Change Order to amend the *** plan to reflect such revised forecast; provided, that such revised forecast shall not result in any adjustment to the Contract Price except when the true-up shows that the actual *** exceed the ***.

(i) As the *** or in situations in which the actual costs for such Work either: (a) shows a variance (increase or decrease) as compared to *** for such Work as reflected in Exhibit I, or (b) such Work is completed and the actual, final price differs from the *** for such Work as reflected in Exhibit I, as applicable, Owner shall issue a Change Order to adjust the Contract Price. As a result of such Change Order, Contractor shall issue either a debit or credit, as applicable, to its subsequent monthly Invoice(s) to reflect any change in Contract Price pursuant to such Change Order, unless the Parties mutually agree to allocate the impact of such Change Order through a revision and reforecast to future Milestone Payments in the Milestone Payment Schedule in Exhibit F-1.

(ii) If a *** plan set forth in Exhibit F-2 shows a variance (either above or below) in *** as compared to the *** plan set forth in Exhibit F-2 for such date, Contractor shall issue either a debit or credit, as applicable, to its next monthly Invoice to reflect the variance between the *** plan. Such adjustment shall not be a Change or entitle Contractor to a Change Order, except the *** plan may be adjusted to the extent such variance affects the *** plan set forth in Exhibit F-2.

(a) If any Invoice is deficient in any material respect, Contractor shall be required to resubmit that Invoice in proper form; provided, however, that Owner shall pay any portion of it that is not deficient or subject to dispute. Owner shall review each Invoice and shall endeavor to make exceptions, if any, by providing Contractor with written notice fifteen (15) Days after Owner receives the Invoice and such substantiating documentation and materials as Owner may have reasonably required. Notwithstanding anything in this Article to the contrary, the failure of Owner to raise an exception shall not preclude Owner from subsequently seeking, and Contractor from paying, a refund of any amounts to which Contractor was not entitled under this Agreement, and Owner may,

by any payment pursuant to Section 7.3(b) below, make any correction or modification that should properly be made to any amount previously considered due.

(b) If Owner provides no exceptions within such time period, Owner shall pay Contractor, within thirty (30) Days of receipt of the Invoice and such substantiating documentation and materials as Owner may have reasonably required, in U.S. dollars the amounts designated in such Invoice, plus any additions and less any deductions which may have become due under this Agreement, as reflected in the Invoice. Any amount of an Invoice that Owner disputes shall be resolved promptly in accordance with Article 28. Once the dispute is resolved, Owner or Contractor, as applicable, shall pay any amount owing promptly after the date of the final resolution. If for any reason Owner fails to pay Contractor for all sums due and owing (other than sums that are the subject of a good faith dispute or permitted to be withheld pursuant to this Section 7.3(b)) within thirty (30) Days after receipt of a substantiated Invoice which complies with the requirements of this Article, a late payment charge shall accrue that is based on an annual percentage rate (APR) equal to the Prime Interest Rate plus one percentage point (1%), payable each month or portion thereof that payment is delayed beyond such 30th Day.

(c) If any Services performed or Equipment supplied by Contractor is not in accordance with this Agreement, Owner may withhold from any Invoice the cost of rectification or replacement until such rectification or replacement has been completed, and, if Contractor is failing to perform any Services or provide any Equipment in accordance with this Agreement and Owner has so notified Contractor in writing, Owner may withhold the estimated value of such Work until it has been performed or provided in accordance with this Agreement.

(a) The Parties acknowledge and agree that, in arranging for financing for the Project and in managing its cash flow, Owner is relying on all Milestone Payments to be made in accordance with the Cash Flow in Exhibit F and that any significant excess over the amounts set forth in the Cash Flow Plan would adversely affect Owner’s ability to manage its cash flow. Accordingly and notwithstanding anything to the contrary in this Article (but subject to the last sentence of Section 7.4(b) below), unless otherwise mutually agreed in writing, Contractor shall not submit and Owner shall not be obligated to pay any Invoice with respect to Unit 6 or the Unit 5 Scrubber that would otherwise be due and payable in any given calendar month, calendar quarter or calendar year to the extent that such Invoice, together with all other Invoices issued during such calendar month, calendar quarter or calendar year, as applicable, exceeds the Cash Flow Plan for Unit 6 or the Unit 5 Scrubber, unless otherwise agreed to in writing by Owner, except that Owner shall pay all actual *** anytime when trued-up notwithstanding the Cash Flow Plan. Contractor shall not be entitled to any interest or late payment charge with respect to any amount that cannot be billed and is carried forward pursuant to this Section.

(b) The Parties acknowledge that nothing in this Section limits, and the Parties shall not construe this Section as limiting, Contractor’s ability to accelerate or substitute Milestones, provided that Owner shall not be obligated to pay more than the Cash Flow

Plan for completion of any accelerated or substituted Milestone for any Unit 6 or the Unit 5 Scrubber. The parties also acknowledge and agree that nothing in the Section limits, and the Parties shall not construe this Section as limiting, Contractor’s ability to update the Schedule in accordance with Section 6.2. In the event that the dates for the Milestones set forth in an updated Schedule forecast no longer match the dates for the corresponding Cash Flow Plan, the parties shall cooperate to revise the Cash Flow Plan to match as closely as possible the updated Schedule to the extent that such revisions will not adversely impact the ability of Owner to arrange for financing for the Project and to manage its cash flow as contemplated by this Section.

7.5 Final Payment. Upon achievement of Final Completion of Unit 6 or the Unit 5 Scrubber, Contractor shall submit to Owner an invoice for the final Milestone Payment and other payments due under this Agreement with respect to Unit 6 or the Unit 5 Scrubber (the “Final Payment Invoice”) which shall set forth all remaining amounts due to it pursuant to this Agreement with respect to Unit 6 or the Unit 5 Scrubber. When submitting the applicable Final Payment Invoice, Contractor shall submit a written discharge, in form and substance reasonably satisfactory to Owner, confirming that the total of the applicable Final Payment Invoice represents full and final settlement of all monies due to Contractor under this Agreement with respect to Unit 6 or the Unit 5 Scrubber. If requested by Owner, the applicable Final Payment Invoice shall also include a waiver (or a bond if a Lien exists to indemnify Owner against such Lien) of any Liens; provided, that the waiver or bond shall be conditioned on Contractor receiving payment pursuant to such Final Payment Invoice. The procedures set forth in Section 7.3 above (including application of any late payment charge) shall be followed for payment of the applicable Final Payment Invoice, and Owner shall be entitled to offset against any invoice or Final Payment Invoice any undisputed amounts owing by Contractor to Owner under this Agreement with respect to Unit 6 or the Unit 5 Scrubber, including any undisputed Liquidated Damages as may be applicable.

7.6 Certification by Contractor. In each Invoice, Contractor shall certify as follows:

“There are no known Liens (or such Liens are bonded over) outstanding at the date of this invoice, all amounts that are due and payable to any third party (including Subcontractors) with respect to the Work as of the date of this invoice have been paid or are included in the amount requested in this invoice, and, except for those bills not paid but so included and amounts disputed between Owner and Contractor, there is no known basis for the creation of any Liens except in respect to payments to Subcontractors withheld for proper reasons. Contractor hereby waives and releases, to the extent of the receipt of payment requested in this invoice, any right to any Lien with respect to payment for such portion of the Work included in this invoice.”

7.7 No Acceptance by Payment. Owner’s payment of any invoice, including a Final Payment Invoice, does not constitute approval or acceptance of any item or cost in that invoice nor shall be construed to relieve Contractor of any of its obligations under this Agreement.

7.8 Revenue from Use of Unit 6 and Facility. Owner shall be entitled to all revenue derived from or in connection with operation or use of Unit 6 and the Facility before (as contemplated in Section 10.4) and after the Substantial Completion Date for Unit 6.

8.1 Change Requests. Without invalidating this Agreement, Owner may order changes in the Specifications or the Work consisting of additions, deletions or other revisions (each, a “Change”), including deletion of Unit 6 or the Unit 5 Scrubber (such deletion being only in the event: (x) Owner is denied the DENR permit for Unit 6, or (y) Owner has cancelled the Work associated with Unit 6 or the Unit 5 Scrubber and does not intend to proceed with another contractor for such Work); provided, that Owner may not delete all Work through this Article. Without limiting the generality of the foregoing, Owner may order:

(d) a Change in the levels, lines, position and dimensions of any part of the Project,

(e) execution of additional Services of any kind prudent for the completion of the Work, or

If Owner desires to make a Change, it shall submit a written proposal to Contractor describing the Change requested. Contractor shall promptly review Owner’s proposal and submit to Owner an estimate of the cost to develop a Change Order for such Change, such development costs to be determined on a time and materials basis utilizing the rates set forth in Exhibit K. If the estimated costs to develop the Change Order are reasonably acceptable to Owner, Owner shall promptly provide notice thereof to Contractor in writing. Upon receipt of such notice, Contractor’s Project Manager shall promptly notify Owner in writing, as soon as practicable, either by giving reasons why Contractor, either directly or indirectly through a Subcontractor, could not effect such Change (if this is the case) or by submitting a proposed Change Order, which shall include in reasonable detail:

Contractor shall provide Owner such supporting documentation for the foregoing as Owner may reasonably request. Notwithstanding the foregoing, Contractor shall not be entitled to any increase in the Contract Price or any extension of the Schedule if such Change was necessary as a result of a breach by Contractor of this Agreement. Owner shall, as soon as practicable after receipt of such submittal and supporting documentation, respond with any comments or questions. Contractor shall not delay any Work while awaiting a response. If Owner responds with comments or questions, Contractor shall endeavor to address such comments or answer such questions as soon as practicable. If Owner decides not to proceed with a Change, it shall reimburse Contractor for its efforts in developing the estimates and other information regarding the potential Change, on a time and material basis utilizing the rates set forth in Exhibit K (such reimbursement to be either outside the Contract Price or through a separate Change Order); provided, that Owner shall only be required to reimburse Contractor if Contractor has complied with the cost proposal requirements set forth above. If Owner wishes to proceed with the Change, Owner shall issue a written order to Contractor authorizing the Change and setting forth any revisions to this Agreement necessary to effect the Change (the “Change Order”). If Contractor refuses to accept such necessary revisions in the Change Order, Owner shall be entitled to require Contractor to continue to perform its obligations hereunder as would be modified by the Change Order; provided, that, if Owner requires Contractor to so perform, (x) the Parties shall resolve the Dispute over the necessary revisions in accordance with the dispute resolution procedures set forth in Article 28 and (y) if the Change requires additional or disputed Work, Owner shall continue to pay Contractor pursuant to the payment terms hereof based, subject to resolution of the Dispute pursuant to Article 28, on the time and materials rates set forth in Exhibit K. Once the Dispute is resolved, any amount owing will be paid within thirty (30) Days after the date of resolution.

If Contractor experiences an increase in costs or a delay in Contractor’s ability to perform the Work due to a delay in the delivery of any Owner Equipment or a delay resulting from a defect in any Owner Equipment or a breach of the Owner Equipment Contracts by the suppliers of the Owner Equipment, and such delay or defect is not the result of Contractor’s failure to comply with the requirements of this Agreement, Contractor shall be entitled to a Change and an equitable adjustment in the Contract Price and/or the Schedule.

Contractor shall have the right to request a Change but shall have no right to require a Change which is not contemplated by this Agreement without the prior written consent of Owner. If Contractor determines that a Change is necessary or advisable for any reason, including a Change in Law, Contractor shall give Owner written notice within twenty-one (21) Days thereof.

Owner may include in any Change Order provision that any additional Services shall be performed and any additional Equipment shall be provided on a time and materials basis. Contractor shall then be paid for such Work under the terms set out in Exhibit K. Contractor shall furnish to Owner such receipts or other vouchers as may be necessary to prove the amounts paid and labor performed and, before ordering materials, shall submit to Owner quotations for the same for its approval (such approval not to be unreasonably delayed or withheld). Promptly after the end of each month, Contractor shall deliver to Owner a priced statement of the labor and materials used during such month associated with such Change.

9.1 Event of Force Majeure. The performance by Owner or Contractor under this Agreement shall be excused to the extent that such Party’s performance is delayed or prevented by reason of an event of Force Majeure. If a Party is or will be reasonably prevented from performing its obligations under this Agreement by an event of Force Majeure, such Party shall use all commercially reasonable efforts to remove the cause affecting such non-performance and to minimize any delay in or impact upon the performance of this Agreement or any damage to or other impact upon the Equipment or the Owner Equipment. If an event of Force Majeure occurs, the Parties shall negotiate ***, and (b) the Contract Price; provided, that Contractor shall *** on Change Orders which result from an event of Force Majeure.

9.2 Notice. If a Party is or will be reasonably prevented from performing its obligations under this Agreement by an event of Force Majeure, then it shall notify the other Party of the obligations, the performance of which is or will be prevented, and the nature and cause of the event in writing within thirty (30) Days after the notifying Party or its Project Manager becomes aware, through the exercise of reasonable diligence, of the event of Force Majeure. The Party affected by an event of Force Majeure shall provide the other Party with weekly updates (a) estimating its expected duration, the cost of any remedial action, and the probable impact on the performance of its obligations hereunder, (b) of the actions taken to remove or overcome the event of Force Majeure and (c) of the efforts taken to mitigate or limit damages to the other Party. The Party affected by an event of Force Majeure shall also provide written notice to the other Party when it ceases to be so affected.

9.3 Suspension; Termination Due to Force Majeure. If any event of Force Majeure by Contractor delays Contractor’s performance for an aggregate time period greater than *** consecutive Days, then Owner, in its sole and absolute discretion, shall have the right to terminate this Agreement without penalty upon payment of all due and owing payments in accordance with Article 23. If any event of Force Majeure by Owner delays Contractor’s performance for an aggregate time period greater than *** consecutive Days, then Contractor, in its sole and absolute discretion, shall have the right to suspend performance and demobilize under this Agreement without penalty in accordance with Section 23.7. If any event of Force Majeure delays Contractor’s performance in any three year time period for an aggregate time period greater than *** Days, then Contractor, in its sole and absolute discretion, shall have the right to terminate performance and demobilize under this Agreement without penalty, and such termination shall be deemed and treated as a termination under Section 23.4.

10.1 Mechanical Completion Inspection. At least thirty (30) Days prior to the date upon which Contractor expects that Unit 6 or the Unit 5 Scrubber will satisfy the conditions for Mechanical Completion set forth in Section 11.1, Contractor shall notify Owner in writing thereof and shall take necessary measures to allow a preliminary Mechanical Completion inspection of the relevant Unit 6 or the Unit 5 Scrubber to be conducted by Owner and its representatives. Contractor shall include with such notice documents and information prudent or convenient for Owner to determine whether Unit 6 or the Unit 5 Scrubber will satisfy the

conditions for Mechanical Completion set forth in Section 11.1. If Owner notifies Contractor of any deficiencies in the Work, Contractor shall immediately remedy such deficiencies as part of the Contract Price and provide Owner with the relevant documentary evidence of the correction.

10.2 Performance Testing. As soon as reasonably practicable following Mechanical Completion of Unit 6 or the Unit 5 Scrubber as set forth in Article 11 below, and after providing Owner at least five (5) Days prior written notice (unless Owner agrees to a shorter notice period or regulatory requirements necessitate a longer notice period), Contractor shall commence Performance Testing of Unit 6 or the Unit 5 Scrubber. All Performance Testing shall be conducted in accordance with the Testing Procedures developed in accordance with the requirements of Exhibit L-1 or Exhibit L-2, as applicable, and approved by Owner (such approval not to be unreasonably withheld or delayed). Owner and its agents, representatives and invitees, including any independent third party inspector, shall have the right to attend and witness the Performance Testing. After the completion of each successful Performance Test, Contractor shall determine and submit to Owner, in writing and electronically, the raw data and completed results of such Performance Test, together with a comparison of such results to the applicable Performance Guarantees and a statement whether such results satisfy the applicable Performance Guarantees. By submitting such raw data and completed results, Contractor represents that such raw data, and the conversion of such raw data into the test results, is accurate. All Performance Testing shall be conducted in conformance with the applicable requirements of this Agreement and the Testing Procedures and with the required prior notification to Owner.

10.3 Satisfaction of Performance Testing. Within ten (10) Days after it receives the results for all of the Performance Testing, the underlying raw data and other information required by Section 10.2, Owner shall respond in writing to Contractor stating whether (a) such Performance Testing was performed according to the Testing Procedures, and (b) the results of such Performance Testing satisfied the applicable Performance Guarantees, or, if Owner does not believe that is the case, Owner shall provide its reasons therefore. Upon its receipt of any such response from Owner that is not in the affirmative, Contractor shall promptly take whatever action shall be necessary to cure the defect in the Performance Testing, adjust or modify any of the Equipment, or request adjustment or modification of Owner Equipment in accordance with Section 3.1(a)(ii), or otherwise in order to satisfy the applicable Performance Guarantees so noted by Owner and shall promptly repeat the Performance Testing in accordance with Section 10.2 and this Section. If, following the Performance Testing, either: (a) Owner agrees that the Performance Guarantees have been satisfied and that the Performance Testing was performed according to the Testing Procedures, (b) the failure to meet any Performance Guarantees is attributable to the performance of Owner Equipment (other than due to Contractor’s obligations set forth in Section 3.1(a)(ii)(B)), or (c) Owner fails to respond within the time period set forth above, then the applicable Performance Guarantees shall be deemed to have been satisfied on the date of completion of such Performance Testing for the purposes of calculating Delay Liquidated Damages. Notwithstanding anything in this Article to the contrary, no agreement, confirmation, statement or otherwise of Owner relating to whether the Performance Testing was performed according to the Testing Procedures or whether the results of such Performance Testing satisfied the applicable Performance Guarantees shall relieve Contractor of any of its obligations under this Agreement. All costs that Contractor incurs in satisfying its obligations under this Article are the sole responsibility of Contractor and included in the Contract Price, except that

Contractor shall be reimbursed through a Change Order for additional costs it may incur due to problems with Owner Equipment that are not the result of Contractor’s failure to comply with the requirements set forth in this Agreement (other than Section 3.1(a)(ii)(A)), including for any repeat Performance Testing and the consumables and spare parts associated therewith.

10.4 Owner’s Right to Operate Prior to Satisfaction of Performance Guarantees. If Unit 6 or the Unit 5 Scrubber fails to satisfy the Performance Guarantees during the Performance Testing for Unit 6 or the Unit 5 Scrubber or fails to achieve Substantial Completion by the Guaranteed Substantial Completion Date for Unit 6 or the Unit 5 Scrubber and Unit 6 or the Unit 5 Scrubber can be operated in compliance with applicable Laws, Owner, in its sole discretion, shall have the right nonetheless to operate Unit 6 or the Unit 5 Scrubber and shall give Contractor written notice of its decision; provided; that if by doing so Owner would cause material damage or deterioration to Unit 6 or the Unit 5 Scrubber, Contractor shall not be responsible for such material damage or deterioration to Unit 6 or the Unit 5 Scrubber to the extent caused by Owner’s election to operate prior to Contractor having an opportunity to cure any Defects. If Owner elects to operate Unit 6 or the Unit 5 Scrubber and, during such time, does not permit Contractor to cure the Defects necessary for Unit 6 or the Unit 5 Scrubber to satisfy the Minimum Performance Guarantees of Unit 6 or the Unit 5 Scrubber, then the Guaranteed Substantial Completion Date and Guaranteed Final Completion Date (if such dates have not passed) for Unit 6 or the Unit 5 Scrubber shall be extended on an equitable basis until such time as Owner tenders Unit 6 or the Unit 5 Scrubber to Contractor for further Services and Performance Testing, and Contractor shall be entitled to a Change Order for equitable schedule and/or price adjustment. Owner shall bear the risk of loss during such time as it operates Unit 6 or the Unit 5 Scrubber. Owner’s operation of Unit 6 or the Unit 5 Scrubber under this Section shall not reduce Contractor’s obligations under this Agreement, including Contractor’s obligation to cause Unit 6 or the Unit 5 Scrubber to satisfy the Specifications and Performance Guarantees for Unit 6 or the Unit 5 Scrubber, except for normal wear and tear, degradation, and operation not in accordance with Contractor’s instructions. In any event, if Owner elects to operate any Unit 6 or the Unit 5 Scrubber as contemplated in this Section 10.4 for more than *** Days, then Substantial Completion of Unit 6 or Unit 5 Scrubber shall be deemed to have been achieved on the day Owner made such election, and ***.

10.5 Failure of Component to Meet Performance Criteria. If Unit 6 or the Unit 5 Scrubber satisfies the Performance Guarantees of Unit 6 or the Unit 5 Scrubber under this Agreement but an item of Equipment within Unit 6 or the Unit 5 Scrubber does not meet its specific performance criteria as set forth in the Specifications, Contractor shall, in addition to its Warranty obligations hereunder, provide Owner with all commercially reasonably paid assistance in pursuing the available remedies against the Subcontractor which provided such Equipment. This assistance may include but shall not be limited to assistance in enforcing the repair, replacement or refurbishment of the Equipment by Subcontractor or the collection of monetary remedies from the Subcontractor for failure to meet its guarantees. The Owner shall be entitled to the benefits of any recovery from such Subcontractor.

11.1 Mechanical Completion. “Mechanical Completion” shall be deemed to have occurred with respect to Unit 6 or the Unit 5 Scrubber upon the satisfaction of all of the following conditions:

(a) All materials, equipment and systems related to the safe start-up and testing of Unit 6 or the Unit 5 Scrubber shall have been constructed and installed in accordance with this Agreement, including the Specifications and applicable Laws, and in a manner that does not void any warranties, and the Equipment and Owner Equipment shall be mechanically and electrically sound, all required pre-operational testing shall have been satisfactorily completed, and all systems shall have been checked for alignment, lubrication, rotation and hydrostatic and pneumatic pressure integrity.

(b) All systems and components shall have been flushed and cleaned out as necessary, and the Equipment and Owner Equipment shall be ready to support the commencement of Performance Testing;

(d) For Unit 6, Contractor shall have synchronized Unit 6 to the transmission grid as described in Exhibit A;

(e) The Equipment and Owner Equipment shall be capable of being tested in accordance with Exhibit L without damage thereto (including any portion of the Facility) or to any property or injury to any Person and in compliance with all applicable Laws and all permits and licenses required by such Laws;

(g) Contractor shall have provided the training of Owner’s personnel and representatives as required by Exhibit A; and

(h) Contractor shall have delivered to Owner a certificate signed by Contractor certifying that all of the preceding conditions in this Section have been satisfied.

Contractor shall not commence Performance Testing of Unit 6 or the Unit 5 Scrubber until all of the above conditions have been satisfied with respect to Unit 6 or the Unit 5 Scrubber and Contractor shall have provided the required prior notice to Owner of the Performance Testing and given Owner an opportunity to attend.

11.2 Substantial Completion. “Substantial Completion” shall be deemed to have occurred with respect to Unit 6 or the Unit 5 Scrubber upon the satisfaction of all of the following conditions:

(a) Mechanical Completion of Unit 6 or the Unit 5 Scrubber shall have been achieved;

(b) Unit 6 or Unit 5 Scrubber shall be capable of being operated in accordance with the Specifications without damage to Unit 6 or the Unit 5 Scrubber, the Facility or to any property or injury to any Person and in compliance with all Owner Permits, Laws and orders of all Government Authorities then in effect;

(c) Contractor shall have completed the initial Performance Testing of Unit 6 or Unit 5 Scrubber and the results of such initial Performance Testing shall have satisfied the Minimum Performance Guarantees of Unit 6 or Unit 5 Scrubber, all according to the Testing Procedures and the requirements of Article 10;

(d) Contractor shall have completed the performance of the Services with respect to Unit 6 or the Unit 5 Scrubber according to all of the provisions of this Agreement, with the exception of those items specified in the Substantial Completion Punch List with respect to Unit 6 or the Unit 5 Scrubber, which Contractor shall have prepared and for which Contractor shall have received approval from Owner (such approval not to be unreasonably withheld or delayed);

(e) Contractor shall have delivered to Owner the Documentation relating to Unit 6 or the Unit 5 Scrubber that Contractor is required to deliver to Owner pursuant to Exhibit A; and

(f) Contractor shall have delivered to Owner a certificate signed by Contractor certifying that all of the preceding conditions in this Section have been satisfied.

Upon the satisfaction of all of the foregoing conditions, Owner shall accept Unit 6 or the Unit 5 Scrubber, subject to Final Completion of Unit 6 or the Unit 5 Scrubber according to Article 11, by delivering to Contractor notice of that acceptance within a reasonable time, and Contractor shall turn over risk of loss and care, custody, control and operation of Unit 6 or the Unit 5 Scrubber to Owner. For the purposes of calculating Delay Liquidated Damages, the date upon which Contractor submits the certifying notice required by this Section 11.2 (if such notice is accurate) shall be deemed the Substantial Completion Date with respect to Unit 6 or the Unit 5 Scrubber.

11.3 Final Completion. “Final Completion” shall be deemed to have occurred for Unit 6 or for the Unit 5 Scrubber upon the satisfaction of all of the following conditions for Unit 6 or the Unit 5 Scrubber:

(a) for Unit 6 or the Unit 5 Scrubber, Contractor shall have achieved all conditions for Substantial Completion of Unit 6 or the Unit 5 Scrubber;

(b) Contractor shall have completed the Performance Testing of Unit 6 or Unit 5 Scrubber and either (i) all Performance Guarantees of Unit 6 or the Unit 5 Scrubber shall have been satisfied according to the Testing Procedures, or (ii) Contractor shall have satisfied all of the Make Right Performance Guarantees of Unit 6 or the Unit 5

Scrubber and shall have paid to Owner Performance Liquidated Damages as required by Article 12 for those guarantees that allow a performance buy-down;

(c) The performance of the Services (except for Services relating to any warranty Work) shall be one hundred percent (100%) complete, including the Reliability Testing and the completion (or buying down) by Contractor of all items on the Substantial Completion Punch List with respect to Unit 6 or the Unit 5 Scrubber in accordance with this Agreement;

(d) Contractor shall have delivered to Owner the Documentation Contractor is required to deliver to Owner pursuant to Exhibit A as of the Final Completion Date for Unit 6 or the Unit 5 Scrubber;

(e) There shall exist no Default of Contractor and no event which, with the passage of time or the giving of notice or both, would be an Default of Contractor; and

(f) Contractor shall have delivered to Owner a certificate signed by Contractor certifying that all of the preceding conditions in this Section have been satisfied.

(a) The Parties agree that it would be extremely difficult and impracticable under presently known and anticipated facts and circumstances to ascertain and fix the actual damages Owner would incur if Contractor does not achieve Substantial Completion of Unit 6 by the Guaranteed Substantial Completion Date for Unit 6 (as the Guaranteed Substantial Completion Date for Unit 6 may be extended due to Force Majeure, Owner caused delays, differing site conditions, discovery of Hazardous Materials, Changes in Law, or as otherwise contemplated in this Agreement), and, accordingly, if Contractor does not achieve Substantial Completion of Unit 6 by that date, subject to Section 12.1(c) below, Owner’s sole and exclusive remedy for such delay shall be to recover from Contractor as liquidated damages, and not as a penalty, the Delay Liquidated Damages for each Day that Substantial Completion of Unit 6 is delayed beyond the Guaranteed Substantial Completion Date for Unit 6; provided, that in no event shall the aggregate Delay Liquidated Damages for Unit 6 exceed its Delay Liquidated Damages Cap.

(b) The Parties agree that it would be extremely difficult and impracticable under presently known and anticipated facts and circumstances to ascertain and fix the actual damages Owner would incur if (i) Unit 5 Scrubber Tie-In does not commence by the Guaranteed Tie-In Commencement Date, (ii) Contractor does not complete the successful tie-in of the Unit 5 Scrubber by the Guaranteed Tie-In Completion Date or (iii) after the successful Tie-In of the Unit 5 Scrubber, Contractor does not achieve Substantial Completion of the Unit 5 Scrubber by the Guaranteed Substantial Completion Date (in each case, as the Guaranteed Tie-In Commencement Date, the Guaranteed Tie-in

Completion Date or the Guaranteed Substantial Completion Date of the Unit 5 Scrubber, as applicable, may be extended due to Force Majeure, Owner caused delays, differing site conditions, discovery of Hazardous Materials, Changes in Law, or as otherwise contemplated in this Agreement), and, accordingly, upon the occurrence of either event, subject to Section 12.1(c) below, Owner’s sole and exclusive remedy therefore shall be to recover from Contractor as liquidated damages, and not as a penalty, the Delay Liquidated Damages for each Day after the Guaranteed Tie-In Commencement Date that Unit 5 Scrubber Tie-In does not commence, each Day after the Guaranteed Tie-In Completion Date that the successful Tie-In of the Unit 5 Scrubber has not been achieved, and, after the successful Tie-In of the Unit 5 Scrubber has been achieved, each Day after the Guaranteed Substantial Completion of the Unit 5 Scrubber that Substantial Completion of the Unit 5 Scrubber is not achieved, as applicable; provided, that in no event shall the aggregate Delay Liquidated Damages for the Unit 5 Scrubber exceed its Delay Liquidated Damages Cap. The Parties hereby agree that the Delay Liquidated Damages payable pursuant to this Section 12.1(b) shall not be duplicative. By way of example, if Contractor is assessed Delay Liquidated Damages due to the commencement of Unit 5 Scrubber Tie-In on a date that is two (2) days after the Guaranteed Tie-In Commencement Date, Contractor shall not be liable for Delay Liquidated Damages for the same two (2) day delay in completing Unit 5 Scrubber Tie-In or in achieving Substantial Completion of the Unit 5 Scrubber.

(c) Contractor shall have no liability or obligation to pay Delay Liquidated Damages to Owner hereunder for any delay in Contractor’s performance of the Work to the extent attributable to the performance of any Owner Equipment, unless such delay is the result of Contractor’s failure to comply with the requirements set forth in this Agreement.

(a) The Parties agree that it would be extremely difficult and impracticable under presently known and anticipated facts and circumstances to ascertain and fix the actual damages Owner would incur if Unit 6 or the Unit 5 Scrubber does not meet the corresponding Performance Guarantees on or before the Guaranteed Final Completion Date for Unit 6 or the Unit 5 Scrubber, and, accordingly, and subject to Section 12.2(c) below, Owner’s sole and exclusive remedy for such failure shall be to recover from Contractor as liquidated damages, and not as a penalty, the applicable Performance Liquidated Damages; provided, however, that in no event shall the aggregate Performance Liquidated Damages for Unit 6 or the Unit 5 Scrubber exceed the respective Performance Liquidated Damages Cap.

(b) Notwithstanding anything set forth in Section 12.2(a) to the contrary, Contractor shall have the right, exercisable by written notice to Owner, to delay the payment of Performance Liquidated Damages by Contractor with respect to Unit 6 or the Unit 5 Scrubber and to continue to use all commercially reasonable efforts to achieve the Performance Guarantees of Unit 6 or the Unit 5 Scrubber for a period of up to *** after the Guaranteed Final Completion Date for Unit 6 or the Unit 5 Scrubber.

(c) Contractor shall have no liability or obligation to pay any Performance Liquidated Damages to Owner hereunder for the failure to meet any Performance Guarantee to the extent that such failure is attributable to the performance of any Owner Equipment, unless such failure is the result of Contractor’s failure to comply with the requirements set forth in Section 3.1(a)(ii)(B).

12.3 Early Completion Bonus. Owner shall pay Contractor the Early Completion Bonus for Unit 6 for Contractor’s early achievement of Substantial Completion of the Work for Unit 6 as compared to the Guaranteed Substantial Completion Date for Unit 6. Contractor shall only be entitled to such Early Completion Bonus if the Work meets the Minimum Performance Guarantees for Unit 6 at the time of Substantial Completion of Unit 6.

12.4 Payment. Unless disputed in good faith, the Liquidated Damages specified in Section 12.1, Section 12.2 and the Bonus specified in Section 12.3 shall be due and payable within thirty (30) Days after written demand by Owner or Contractor, as the case may be. Any undisputed Liquidated Damages or Bonus that remain unpaid after the expiration of such ten-Day period shall bear interest at the Prime Interest Rate plus 1% per annum or the highest rate allowed by law, whichever is less. If any Liquidated Damages or Bonus are disputed by either Party, any Liquidated Damages or Bonus that are determined to be payable pursuant to the resolution of such dispute in accordance with this Agreement shall also bear interest from the expiration of the ten-Day period referred to above at the Prime Interest Rate plus 1% per annum or the highest rate allowed by law, whichever is less. Notwithstanding the assessment of interest, and in addition to its other rights and remedies, Owner and Contractor shall have the right to offset the amount of any unpaid Liquidated Damages or Bonus plus interest against any amounts due or that may become due to Contractor or Owner (as the case may be) under this Agreement.

13.1 Services Warranty Period. Contractor warrants that the Services will be performed in a professional and workmanlike manner, will conform to the requirements of this Agreement, including the requirements set forth in Section 3.1(a)(ii), and will reflect competent professional knowledge and judgment. For Unit 6 and the Unit 5 Scrubber, if any portion of the Services fails to comply with this warranty obligation and Contractor is so notified in writing prior to *** after the respective Substantial Completion Date (the “Services Warranty Period”), Contractor will promptly re-perform such portion of the Services without additional compensation from Owner or, if re-performance is impossible or commercially impracticable, Owner and Contractor shall meet and discuss in good faith an equitable way to resolve such matter in order to place Owner in as good a position as Owner would have been in had there been no such breach of the warranty obligation. If the Parties are unable to resolve such matter in a manner reasonably acceptable to both Parties, either Party may initiate the Dispute resolution procedures set forth in Article 28.

13.2 Equipment Warranty Period. Contractor warrants that the Equipment furnished to Owner will be free from Defects in workmanship and material and will conform to this Agreement, including the Specifications, for a period of *** from the earlier of (a) the date care, custody and control to the Equipment is transferred to Owner, or (b) the date Substantial Completion of Unit 6 or the Unit 5 Scrubber is achieved. Notwithstanding the foregoing, the Equipment Warranty Period for each item on a Substantial Completion Punch List shall

commence upon Contractor’s completion (or buying down) of, and Owner’s acceptance of, the particular Punch List item and shall continue until the *** thereof (the warranty periods set forth in this Section are, collectively, referred to as the “Equipment Warranty Period”).

13.3 Extension of Warranty Periods. If a Defect (as defined in Section 13.4) is discovered within the Services Warranty Period or Equipment Warranty Period, as applicable, and such Defect is not cured to the reasonable satisfaction of Owner, then the Services Warranty Period or Equipment Warranty Period, as applicable, shall be extended to the *** of the date such Defect was corrected, but only with respect to the Equipment or Service that was the subject of such Defect. In no event shall any Services Warranty Period or Equipment Warranty Period for Unit 6 or the Unit 5 Scrubber extend beyond *** from the Substantial Completion Date for Unit 6 or Unit 5 Scrubber, respectively.

13.4 Defects. If, within the Services Warranty Period or Equipment Warranty Period, as applicable, deviations from, breaches of, or failures of the foregoing warranties (“Defects”) in the Equipment or Services are discovered by Owner or Contractor, Contractor shall, commence within a timely manner upon being discovered or upon notice from Owner to correct those Defects, including re-performance or re-provision of any affected portion of the Work and repair of any resulting damage, and shall demonstrate to Owner’s reasonable satisfaction that the Defects have been properly corrected. Warranty work critical to the operation of the Facility shall be performed at such time and in such manner as to take into consideration Owner’s requirements to avoid disruption of Owner’s operations at the Facility. Contractor shall be responsible for, and shall pay as and when due for, all inspection, removal, packaging, transportation, installation, consulting and other costs for the correction of Defects. Owner shall provide Contractor with reasonable access at the Site to correct Defects; provided, that any such access shall be restricted, and subject to such conditions, as Owner may have instituted generally for its contractors.

13.5 Responsibility for Warranty Work. Contractor shall have primary liability with respect to the warranties in this Agreement, whether or not any Defect or other matter is also covered by a warranty of a Subcontractor or other third party, and Owner need only look to Contractor for corrective action. In addition, Contractor’s warranties shall not be restricted in any manner by any warranty of a Subcontractor or other third party, and the refusal of a Subcontractor or other third party to provide or honor a warranty or to correct defective, deficient or nonconforming Work shall not excuse Contractor from its liability on its warranties to Owner. Contractor shall have no responsibility to perform any warranty Work with respect to Owner Equipment unless any Defect with respect to such Owner Equipment is attributable to Contractor’s failure to comply with the requirements set forth in Section 3.1(a)(ii)(B).

13.6 Conditions of Warranty. To the extent that any failure by Contractor to meet the foregoing warranties is the result of (a) Owner’s failure to receive, handle, store, maintain, or install the Equipment furnished in a reasonable manner or in accordance with any reasonable Contractor requirements conveyed to Owner, (b) Owner’s failure to operate the Equipment within its rating or operated and maintained in a reasonable manner consistent with Contractor’s or Equipment vendors’ instructions, (c) Owner subjecting the Equipment to abuse or misuse, or (d) normal wear and tear or corrosion inherent in the operation of the Facility, then, to that extent, Contractor shall be excused for said failure.

13.7 Title Warranty. Contractor represents and warrants that it shall provide to, and, effective as of the applicable date set forth in Section 22.1, hereby assigns and transfers to, Owner good, marketable and exclusive title to the Equipment, free and clear of all Liens (other than Liens created solely by the actions of Owner); provided, however, that Contractor shall not be required to assign and transfer to Owner good, marketable and exclusive title to certain intellectual property to be licensed to Owner as provided in Article 19, but Contractor shall, and hereby does, grant, effective upon the date on which Owner takes over care, custody and control of the Facility, to Owner the licenses to such intellectual property as described in Article 19. In the event of any nonconformity with or breach of this warranty, Contractor shall, as part of the Fixed Prices, promptly, and in any event within thirty (30) Days thereof, remove any Lien on any of such Equipment or otherwise provide Owner good, marketable and exclusive title to such Equipment, free and clear of all Liens; provided, that if Contractor is unable within such thirty (30) Day period to remove such Lien, Contractor may post a bond in an amount (and otherwise in form and substance) reasonably acceptable to Owner so long as Contractor continues to use all commercially reasonable efforts to remove such Lien as promptly as practicable. This Section shall survive the expiration, cancellation or termination of this Agreement.

13.8 Intellectual Property Warranty. Contactor warrants that the Services performed by Contractor or its Subcontractors, the Equipment and the Documentation, or any part of any of the foregoing, shall not infringe or constitute a misappropriation of any right of any third party, including, without limitation, any copyrights, mask work rights, patent rights, trademark rights, trade secret rights or confidentiality rights.

13.9 Warranty Assistance. During the Warranty Periods, Owner shall, without cost to Contractor: (a) provide Contractor reasonable working access (subject to such restrictions and conditions as Owner may have instituted generally for its contractors) to the Site to remove, disassemble, replace and reinstall any Equipment with respect to which a Defect exists; (b) remove, to the extent erected by Owner or a third party and not included in, or required by, the Specifications and to the extent necessary to permit Contractor to perform its warranty obligations, any material or structures; and (c) provide Contractor reasonable access to Facility personnel as are reasonably necessary to the extent consistent with personnel job classifications and subject to availability to assist Contractor in the performance of its warranty obligations.

13.10 Exclusive Warranties. THE WARRANTIES SET FORTH IN THIS AGREEMENT ARE EXCLUSIVE AND ARE IN LIEU OF ALL OTHER WARRANTIES WHETHER STATUTORY, EXPRESS, OR IMPLIED (INCLUDING ALL WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, AND ALL WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE OF TRADE). Correction of Defects in the manner and within the period of time provided herein shall constitute complete fulfillment of all the liabilities of Contractor with respect to such Defect, whether the claims by Owner are based in contract, in tort (including negligence and strict liability), or otherwise.

14.1 Contractor’s Indemnity. Contractor shall indemnify and hold harmless Owner, its parents and Affiliates, and their respective partners, shareholders, members, agents, employees, officers, directors, and lenders and Financial Institutions (collectively, the “Owner Indemnitees”) from and against:

(i) any and all Third Party Claims and all damages, liabilities, losses, costs and expenses associated therewith (including attorneys’ fees and other professionals’ fees) for any injury of or death to persons, damage to or destruction of third party property, contamination of the environment or injury to natural resources, whether contractual, in tort, or as a matter of strict liability or liability imposed by Law, to the extent any of the foregoing arise out of the negligence or willful misconduct or wanton acts or omissions of Contractor, any Subcontractor or any of their respective employees, agents or third parties over which either has reasonable control during the performance of the Services, including any Services during any Warranty Period, and

(ii) any and all claims, demands or causes of action of every kind and character by any Person and all damages, liabilities, losses, costs and expenses associated therewith (including attorneys’ fees and other professionals’ fees) for:

14.2 Owner’s Indemnity. Owner shall indemnify and hold harmless Contractor, its parents and Affiliates and their respective partners, shareholders, members, agents, employees, officers, directors, and lenders (collectively, the “Contractor Indemnitees”) from and against:

(i) any and all Third Party Claims and all damages, liabilities, losses, costs and expenses associated therewith (including attorneys’ fees and other professionals’ fees) for any injury of or death to persons, damage to or destruction of third party property, contamination of the environment or injury to natural resources, whether contractual, in tort, or as a matter of strict liability or liability imposed by Law, to the extent any of the foregoing arise out of, in whole or in part, the negligence or willful misconduct or wanton acts or omissions of Owner or any of its employees, agents or third parties over which it has reasonable control during the performance of the Services, including any Services during any Warranty Period; and

14.3 Intellectual Property Indemnity. Contractor shall, as part of the Fixed Prices, defend, indemnify and hold harmless Owner Indemnitees against any and all damages, liabilities, losses, costs and expenses (including attorneys’ fees and other professionals’ fees) associated with any claims, suits or proceedings brought against any of the Owner Indemnitees based on an allegation that any Services performed by Contractor or its Subcontractors, the Documentation or the Equipment, or any part thereof, or use thereof, constitutes an infringement or misappropriation of any right of any third party, including, without limitation, any copyrights, mask work rights, United States patent rights, trademark rights, trade secret rights, confidentiality rights or other property rights, if Contractor is notified promptly in writing and given authority, information, and assistance for the defense or settlement of such claim suit or proceeding. Contractor will not be responsible for any settlement of such suit or proceeding made without its written consent. Contractor shall obtain Owner’s written consent, which may be withheld in Owner’s sole discretion, prior to entering into any settlement of any such claim suit or proceeding that does not include a complete liability release for all Owner Indemnitees or that would prohibit use of any part of the Project, the Documentation or the Equipment by any Owner Indemnitees. If the use of the Project, the Documentation or the Equipment, or any part thereof, as a result of any such claim, suit or proceeding is held to constitute infringement, and its use by any of the Owner Indemnitees is enjoined, Contractor shall, at its option, either: (i) procure for such Owner Indemnitees the right to continue using the Project, the Documentation or the Equipment, or any part thereof; (ii) replace same with substantially equivalent non-infringing Documentation or Equipment or parts thereof acceptable to Owner; or (iii) modify same in a manner acceptable to Owner and in conformance with the functional requirements of this Agreement so it becomes non-infringing. Except to the extent that Contractor is a contributory infringer, Contractor shall have no indemnity duty or obligation hereunder to the extent that the Facility, the Documentation or the Equipment furnished hereunder is (A) modified by Owner after acceptance thereof to make it infringing, or (B) combined by Owner with items not furnished hereunder or recommended or approved by Contractor and solely as a result of said modification or combination a claim, suit or proceeding is brought against Owner. Contractor shall flow down the requirements of this Section 14.3 and make Owner direct beneficiary of the indemnification obligation in its subcontracts with all Major Subcontractors. If Contractor is unable to flow down such provision to a Major Subcontractor, Contractor shall notify Owner in writing of such failure prior to entering into a subcontract with such Person and Owner and Contractor shall consult in good faith concerning the options to select an alternative Subcontractor.

Further, upon the passage of title, the Equipment, constituent parts thereof and the unused spare parts shall be specifically excluded from the bankruptcy estate of Contractor in the event of any bankruptcy or insolvency proceeding involving Contractor. Regardless of whether title has passed to Owner, Contractor hereby grants Owner a continuing security interest in all of the Equipment to the extent of the payments made in connection therewith, whether now owned or hereafter acquired, wherever located and all attachments and accessions thereto and all replacements thereof, all drawings, plans and general intangibles related thereto, all warranties and contract rights related thereto and all proceeds of the foregoing (collectively, the “Collateral”), to secure all past, present and future indebtedness and obligations which Contractor owes Owner under this Agreement. Contractor shall cause such security interest to constitute, at all times, a valid, enforceable, duly perfected, first priority security interest in the Collateral superior to all other claims to and interests in the Collateral, including the claims of any lender, vendor or Subcontractor to Contractor, it being understood that Owner shall be responsible for initial perfection of such security interest. Contractor hereby authorizes Owner to file financing statements naming Contractor as debtor with respect to the Collateral in such jurisdictions as Owner believes are necessary to perfect the foregoing security interest.

Contractor represents that all Contractor and Subcontractor personnel have received all necessary training regarding environmental, OSHA and any other matters required by applicable Laws and relevant to the Work. Training on implementation of any additional environmental mitigation measures appropriate for the Work will be specified by Owner before commencement of the Services.

25.4 Compliance with Employment Laws; Policies. All Services shall be performed in accordance with all applicable Laws, including worker’s compensation Laws, minimum and maximum salary and wage statutes and regulations, and licensing Laws and regulations. Contractor shall fully reimburse Owner for any and all fines or penalties of whatever kind or type that Owner may incur as the result of and to the extent caused by Contractor’s failure to fully comply with and fulfill any of the provisions of this Article. To the extent commercially reasonably practical, Contractor shall use reasonable efforts to adopt and utilize a subcontracting plan with its first-tier Subcontractors that complies with 48 C.F.R. 52-219-9 for Small Diverse

Suppliers (“SDS”). In addition, Contractor shall (a) utilize SDS as required by law; (b) provide Owner with a quarterly status report in the format set forth on Owner’s website at www.duke-energy.com, or in such other format as is reasonably acceptable to Owner; (c) enter the SDS data in any report on Owner’s website at www.duke-energy.com and (d) provide Owner, its designated auditors and any applicable government agency the right of access during normal business hours to inspect any records related to SDS and compliance with this section.

25.5 Substitution. Contractor reserves the right to change any of its personnel performing Services. In such event, Contractor shall provide replacement personnel meeting the requisite qualifications and who have equal or better capabilities and shall bear any additional travel and living expenses associated with providing such replacement personnel.

26.1 Technical Documentation. Except to the extent applicable Laws require a longer retention, Contractor shall maintain its own, and shall cause its Subcontractors to maintain their own, technical documentation relative to the Equipment and the Owner Equipment for a period of three (3) years after the latest of the Final Completion Dates of Unit 6 and the Unit 5 Scrubber. Contractor shall give Owner thirty (30) Days prior written notice before destroying or disposing of any such documentation or records and a reasonable opportunity for Owner during such period to make copies of any such documentation.

26.2 Accounting Records. Except to the extent applicable Laws require a longer retention, Contractor shall maintain and shall cause its Subcontractors to maintain complete accounting records relating to all Work performed or provided under this Agreement on a time and material, or reimbursement, basis in accordance with generally accepted accounting principles in United States, as set forth in pronouncements of the Financial Accounting Standards Board (and its predecessors) and the American Institute of Certified Public Accountants, for a period of three (3) years after the latest of the Final Completion Dates of Unit 6 and the Unit 5 Scrubber, except that records relating to Sales Taxes for such items must be retained for four (4) years as specified in Section 26.4. Contractor shall give Owner thirty (30) Days prior written notice before destroying or disposing of any such accounting records and a reasonable opportunity for Owner during such period to make copies of any such documentation.

26.3 Owner’s Right to Audit. For verification of incurred or estimated costs, including all related direct costs, claimed by Contractor for reimbursement or for any Work performed or provided on a time and material basis or for any suspended, terminated, delayed or accelerated Services, a third party auditor selected by Owner and reasonably acceptable to Contractor (which acceptance shall not be unreasonably withheld or delayed) shall have the right and access at reasonable times during normal business hours to examine and audit Contractor’s records and books related to all those costs as is reasonably necessary for Owner to verify such costs. Furthermore, Owner or Owner’s representative shall have no right to audit records or books concerning the make-up of any agreed upon lump sum amounts or fixed rates or multipliers. If any audit by the auditor reveals charges or costs charged to or paid by Owner as costs or fees which are not proper or exceed the rates or amounts permitted hereunder for any such matters, then Owner shall be entitled upon demand for a refund from Contractor of all such amounts, plus interest thereon from the date of payment by Owner until the date of refund by Contractor at a

rate of the lesser of (a) the Prime Interest Rate plus 1% or (b) the maximum rate allowed by applicable law. Likewise, if any audit or if any examination by any state or local taxing agency reveals additional Sales Tax to be imposed upon Contractor for under collection of tax from Owner on a taxable sale to Owner, then Contractor shall be entitled, upon demand, for a refund from Owner of all such amounts, plus interest at the foregoing rate.

26.4 Sales Tax and Privilege Tax Records. Contractor shall provide to Owner all information and data Owner may from time to time reasonably request and otherwise fully cooperate with Owner in connection with the reporting of (a) any Sales Taxes and Privilege Taxes payable with respect to the Work and (b) any assessment, refund claim or proceeding relating to Taxes payable with respect to the Work. Contractor shall require its Subcontractors to provide to Contractor all information and data Contractor may reasonably request for purposes of complying with the preceding sentence and otherwise fully cooperate with Owner. Contractor shall retain, and shall require Subcontractors to retain, copies of such documentation and all documentation relating to purchases relating to the Work or the payment of Sales Taxes and Privilege Taxes, if any, for a period of not less than four (4) years from the latest of the Final Completion Dates of Unit 6 and the Unit 5 Scrubber. Contractor shall ensure that its contracts with all Subcontractors effectuate the provision of this Section. Contractor’s and Owner’s obligations under this Section shall survive the termination, cancellation or expiration of this Agreement for any reason and shall last so long as is necessary to resolve any and all matters regarding Taxes attributable to the Work; provided, that if Owner requires Contractor to take action under this Section at any time after the later of (i) two (2) years after delivery of the piece of Equipment or (ii) two (2) years after completion of the particular item of Work, Owner shall reimburse Contractor for all actual and reasonable expenses Contractor incurs in taking those actions.

27.1 Employment Taxes. Neither Owner nor its officers, employees, agents, consultants or other representatives shall have any liability for any payroll or employment compensation taxes, for Social Security taxes, or for labor-related withholding taxes, for Contractor and its Subcontractors (including manufacturers); or any of their employees; and Contractor agrees to hold Owner, his Consultants, and his other contractors harmless against any claim or liability therefore.

27.2 Sales and Use Taxes on Contractor Tools. Contractor shall pay all taxes on Contractor’s purchases of goods, tools, equipment, supplies and other consumables which are not permanently incorporated into the Project and which remain the property of Contractor. Contractor shall also pay all taxes attributable to Contractor’s construction equipment, temporary buildings and other property used by Contractor in its performance of this Agreement. Allowance for such taxes is included in the Contract Price, and Contractor shall pay those taxes when assessed, without claim against Owner for reimbursement. Contractor shall impose a similar obligation on all Subcontractors and shall ensure that no Subcontractor shall have any claim against Owner for reimbursement of those taxes.

27.3 Sales and Use Tax on Equipment; Privilege Tax. Notwithstanding the above, the Contract Price does not include monies for the payment of any sales and use taxes on Equipment incorporated into the Facility. Contractor, on behalf of itself and all of its Subcontractors

(including manufacturers), is therefore responsible for consulting with Owner on Equipment purchases and working with Owner to obtain the appropriate sales and use tax and privilege tax benefits for Owner. Owner is currently authorized under the North Carolina General Statutes to purchase certain Equipment exempt from the sales and use tax, but subject to the privilege tax at a rate of 1% with a maximum tax of eighty dollars ($80) per article. Owner will specifically identify property which will be subject to the privilege tax. Owner will issue Form E-595E to Contractor to support the exemption from the sales and use tax. Contractor shall register with the state of North Carolina for payment of the privilege tax. Contractor will issue Form E-595E to its suppliers to facilitate exempt purchases of property subject to the privilege tax. As required by law, Contractor will accrue the privilege tax on these purchases and remit the appropriate amount to the State. Sales tax should be billed by the supplier on Contractor’s purchases of property subject to the North Carolina sales tax.

(a) Contractor, its Subcontractors, manufacturers and suppliers shall make reasonable commercial efforts to purchase Equipment to minimize the tax, but shall not be restricted from making out-of-state purchases of such Equipment. Contractor shall use its best efforts to ensure that Owner is afforded the appropriate sales/use and privilege tax treatment by the State of North Carolina. Contractor shall use all reasonable efforts to ensure that all out-of-state purchases made by Contractor and its Subcontractors (including manufacturers) are shipped FOB the Facility (North Carolina) free of Sales Taxes. Owner shall reimburse Contractor for all sales and use taxes and privilege taxes paid by Contractor and its Subcontractors (including manufacturers) upon written confirmation from Contractor that the items purchased could not reasonably be purchased free of Sales Taxes.

(b) Contractor agrees that it and its Subcontractors, suppliers, and manufacturers will clearly identify on each original invoice covering the purchase of Equipment, the amount of sales and use tax. Should additional information and detail be required by Owner and the North Carolina Department of Revenue to verify amounts paid for purchases of Equipment under this Agreement, Contractor and its Subcontractors, suppliers, and manufacturers shall supply such additional information and invoices in sufficient detail to verify:

(i) That such Goods were purchased free of State sales and use taxes; or that for out-of-state purchases, the invoices indicate the amount of foreign sales and use tax separately stated and paid;

(ii) The privilege tax was accrued and remitted to North Carolina for such Equipment;

(vi) The Federal Energy Regulatory Commission (FERC) Code identification for such Equipment.

(c) As a condition to Final Completion of Unit 6 or the Unit 5 Scrubber, Contractor shall provide Owner with an affidavit that all invoices which include sales and use taxes or privilege tax have been paid and that Contractor and all its Subcontractors, suppliers, and manufacturers have no outstanding claims or expenses relating to sales and use tax or privilege tax.

(d) Both Parties shall provide to the other any documentation or information requested in order to submit and obtain a refund of any taxes erroneously paid as part of this Agreement. The Parties agree that any refunds received shall belong to the Party which bore the economic burden of paying the tax. The Parties’ obligations under this Section shall survive termination or expiration of the Agreement.

27.4 State Property Taxes. Contractor and Owner agree that Owner shall be responsible for the filing requirements and payment obligations for all state and local taxes on the Site and the Equipment incorporated into the Facility; provided, that Contractor shall be responsible for the filing of property tax returns and the payment of State and local property taxes on construction equipment, tools and material which is not incorporated into the Project and which is owned, used or leased by Contractor to perform the Services. Owner and Contractor acknowledge that construction equipment property tax costs are included in the leasing costs included in the Fixed Prices. If Contractor owns construction equipment and leases such construction equipment to Owner, Contractor shall remain responsible for the filing and payment of all property taxes due on such construction equipment.

(a) Except in cases where such tax assessment is the result of the negligence or willful or wanton misconduct by Contractor, Owner shall defend, reimburse, indemnify and hold Contractor harmless for all costs and expenses incurred by Contractor as a result of Owner’s formal protest of any sales and use taxes paid or assessed and property taxes paid or assessed on the Site or the Equipment, or any other similar tax, whether local, state or federal, including any litigation expenses in the event Owner decides to protest a sales or use tax assessment. Owner shall not be responsible for any costs incurred by Contractor necessary to substantiate or verify information for any tax audit conducted in the normal course of business.

(b) Contractor shall defend, reimburse, indemnify and hold Owner harmless for all costs and expenses incurred by Owner as a result of Contractor’s formal protest of any Employment Taxes, or any sales and use taxes and property taxes paid or assessed on Contractor’s equipment or tools, or of any payroll or employment compensation taxes, or Social Security taxes, or for labor-related withholding taxes, or any other similar tax, whether local, state or federal for Contractor; its Subcontractors (including manufacturers); or any of their employees, paid or assessed, including any litigation expenses in the event Contractor decides to protest the said employment, withholding, and similar taxes.

27.6 Pollution Control Equipment Information. Contractor shall supply Owner with all reasonable information and cost analyses requested by Owner for qualifying air, water or noise pollution control equipment for exemption from sales and use taxes, property taxes and any other

tax credits, refunds or exemptions available to Owner. Contractor shall supply any further information as requested by Owner to apply for a certificate from the North Carolina Department of Environment and Natural Resources (DNHR) or other appropriate Government Authority to qualify for the above exemptions.

28.1 Resolution by the Parties: Mediation. The Parties shall attempt to resolve any claims, disputes and other controversies arising out of or relating to this Agreement (collectively, “Disputes”) promptly by negotiation and mediation between executives who have authority to settle the Dispute and who are at a higher level of management than the persons with direct responsibility for administration of this Agreement. A Party may give the other Party written notice of a Dispute which has not been resolved in the normal course of business. Such notice shall include: (a) a statement of that Party’s position and a summary of arguments supporting such position, and (b) the name and title of the executive who will be representing that Party and of any other person who will accompany the executive. Within five (5) Days after delivery of the notice, the receiving Party shall respond with (i) a statement of that Party’s position and a summary of arguments supporting such position, and (ii) the name and title of the executive who will represent that Party and of any other person who will accompany the executive. Within ten (10) Days after delivery of the summary positions, the Parties shall select a mutually agreeable neutral mediator and the executives of both Parties shall meet with the mediator at a mutually acceptable time and place, and shall meet thereafter as often as they reasonably deem necessary, to attempt to resolve the Dispute. All negotiations pursuant to this clause are to be deemed confidential and shall be treated as compromise and settlement negotiations for purposes of applicable rules of evidence.

(a) Demand for Arbitration. If the Dispute has not been resolved by negotiation within *** Days of the disputing Party’s initial notice (or such longer period as the Parties may reasonably agree), or if the Parties failed to meet for the first time within *** Days of the initial notice, the Parties shall fully and finally settle the Dispute by binding arbitration. All arbitration proceedings shall take place in Charlotte, North Carolina under the auspices of the American Arbitration Association (“AAA”) in accordance with the AAA Construction Industry Arbitration Rules then in effect, and shall be governed by the Federal Arbitration Act, 9 U.S.C. §§ 1-16. For all Disputes where the amount in controversy is less than ***, the arbitration proceedings shall be conducted by a *** selected by the Parties (or by the AAA, if the Parties cannot agree on an arbitrator within *** Days following the delivery of a demand for arbitration to the other Party). For all Disputes where the amount in controversy is equal to or more than ***, the arbitration proceedings shall be conducted by a ***. If the Parties have not agreed on the selection of *** on or before *** Days following the delivery of a demand for arbitration to the other Party, then each Party, by notice to the other Party, may designate *** (who shall not be a current or former officer, director, employee or agent of such Party or any of its Affiliates). The *** designated by the Parties shall endeavor to designate promptly a ***. If either Party fails to designate an initial *** on or before *** Days following the delivery

of an arbitration notice to the other Party, or if the *** have not designated *** within *** Days of the date for designation of the *** initially designated, either Party may request that the AAA designate the remaining *** pursuant to its Construction Industry Arbitration Rules. If any arbitrator resigns, becomes incapacitated, or otherwise refuses or fails to serve or to continue to serve as an arbitrator, then the Party entitled to designate that arbitrator shall designate a successor. The demand for arbitration shall be served on the other Party to this Agreement. No demand for arbitration shall be made or permitted after the date when the institution of a civil action based on the Dispute would be barred by the applicable statute of limitations or repose of the State.

(b) Consolidation. No arbitration arising under this Agreement shall include, by consolidation, joinder or any other manner, any Person not a Party to this Agreement unless (i) such Person is substantially involved in a common question of fact or Laws, (ii) the presence of the Person is required if complete relief is to be accorded in the arbitration, and (iii) the Person has consented to be included.

(c) Equitable Remedies. The procedures specified in this Article shall be the sole and exclusive procedures for the resolution of Disputes between the Parties arising out of or relating to this Agreement; provided, however, that a Party may file a complaint in a court of competent jurisdiction on issues of statute of limitations or repose or to seek injunctive relief, sequestration, garnishment, attachment, or an appointment of a receiver. Preservation of these remedies does not limit the power of the arbitrator(s) to grant similar remedies, and despite such actions, the Parties will continue to participate in good faith in and be bound by the dispute resolution procedures specified in this Article.

(d) Award; Binding Nature. The arbitrator(s)’ decision shall be by majority vote and shall be issued in a writing that sets forth in separately numbered paragraphs all of the findings of fact and conclusions of law necessary for the decision. Findings of fact and conclusions of law shall be separately designated as such. The arbitrator(s) shall not be entitled to deviate from the construct, procedures or requirements of this Agreement. In the absence of bias, fraud, or willful misconduct by an arbitrator, any decision rendered by the arbitrator(s) in any arbitration shall be final and binding upon the Parties, and judgment may be entered on the award in any court of competent jurisdiction. The cost of all arbitrators shall be borne equally by the Parties.

(e) Discovery. Either Party may apply to the arbitrators for the privilege of conducting discovery. The right to conduct discovery shall be granted by the arbitrators in their sole discretion with a view to avoiding surprise and providing reasonable access to necessary information or to information likely to be presented during the course of the arbitration.

28.3 Continuation of Work. Pending the final resolution of any Dispute, Contractor shall proceed diligently with the performance or provision of the Work and its other duties and obligations and Owner shall continue to compensate Contractor as set forth under this Agreement without diminution of effort, including payment to Contractor provisionally on a time and material basis for all disputed work.

29.1 Governing Laws. This Agreement shall be governed by and construed in accordance with the laws of the State, without reference to its conflict of laws principles.

29.2 Entire Agreement.

This Agreement may be amended or modified only by a written instrument duly executed by each of the Parties.

29.3 Successors and Assigns. Neither this Agreement nor any right, interest or obligation hereunder may be assigned by Contactor without the prior written consent of Owner, and any attempt to do so shall be void, except that the whole of this Agreement may be assigned by Contractor upon prior written notice to Owner (a) to a parent company or a wholly-owned Affiliate, provided that Contractor shall not be relieved of any of its obligations hereunder, or (b) to a transferee who acquires all or substantially all of the assets of Contractor and whose market capitalization exceeds *** and whose long term senior unsecured, uninsured debt is rated at least Baa3 by Moody’s or BBB- by Standard & Poor’s at the time of the transfer, or whose creditworthiness is otherwise reasonably satisfactory to Owner. Subject to the preceding sentence, this Agreement is binding upon, inures to the benefit of and is enforceable by the Parties and their respective successors and assigns. Nothing herein shall be construed to limit in any way Contractor from assigning the performance of any Services to an affiliate properly licensed to engineering work in the State of North Carolina but without relieving Contractor from its obligations hereunder. Owner, including any Party constituting Owner, may assign this Agreement or any benefit, interest, right or cause of action arising under this Agreement to any Person with notice to, but without the consent of, Contractor under the following circumstances: (a) the assignee is an Affiliate or subsidiary of the Owner and the assignee has a credit rating that is at least S&P BBB-, Moody’s Baa3 or whose creditworthiness is otherwise reasonably satisfactory to Contractor, (b) the assignee has acquired ownership of, or the right to operate, the Facility for which an assignment is being made and the assignee’s senior unsecured debt has a credit rating of S&P BBB-, Moody’s Baa3, or (c) such assignee is otherwise reasonably acceptable to Contractor. Owner (or the assigning Party that constitutes a part of Owner, as applicable) shall obtain written assurances from the assignee of limitation of and protection against liability following the proposed transfer at least equivalent to that afforded Contractor and Subcontractors hereunder. Any transfer contrary to this Section shall make the assigning Party constituting Owner the indemnitor of Contractor against any liabilities incurred in excess of those that would have been incurred had no such transfer taken place.

29.4 No Third Party Beneficiaries. Except as expressly set forth in this Agreement, the provisions of this Agreement are intended for the sole benefit of Owner and Contractor, and there are no third party beneficiaries.

29.5 Rights Exclusive. The rights and remedies of Owner or Contractor as set forth in this Agreement shall be the exclusive rights or remedies of the Parties.

29.6 No Waiver. No course of dealing or failure of Owner or Contractor to enforce strictly any term, right or condition of this Agreement shall be construed as a waiver of that term,

right or condition. No express waiver of any term, right or condition of this Agreement shall operate as a waiver of any other term, right or condition.

29.7 Survival. Article 14 (Indemnity), Article 17 (Limitations of Liability), Article 19 (Intellectual Property), Article 20 (Confidentiality), Article 27 (Taxes), Article 28 (Dispute Resolution), Article 29 (Miscellaneous) and all other Sections providing for indemnification or limitation of or protection against liability of either Party shall survive the termination, cancellation, or expiration of this Agreement.

29.8 Severability. If any provision of this Agreement or the application of this Agreement to any Person or circumstance shall to any extent be held invalid or unenforceable by a court of competent jurisdiction or arbitrators under Article 28, then (i) the remainder of this Agreement and the application of that provision to Persons or circumstances other than those as to which it is specifically held invalid or unenforceable shall not be affected, and every remaining provision of this Agreement shall be valid and binding to the fullest extent permitted by Laws, and (ii) a suitable and equitable provision shall be substituted for such invalid or unenforceable provision in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision.

or to such other address, attention or facsimile number as such Party to whom such notice is to be addressed shall have hereafter furnished to the other Party in writing as provided in this Article.

29.10 Vienna Convention.

29.11 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

IN WITNESS WHEREOF, the Parties have duly executed this Agreement as of the date first above written.

WHEREAS, Owner has entered into a Engineering, Procurement and Construction Agreement dated July 11, 2007 (the “Contract”) with Stone and Webster National Engineering P.C. (“Contractor”), whereby Contractor will provide certain services for the Project; and

WHEREAS, as a condition to Owner entering into the Contract with Contractor, Guarantor must guaranty the obligations of Contractor under the Contract in accordance with the terms set forth herein; and

NOW, THEREFORE, in consideration of the foregoing premises and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, Guarantor hereby agrees as follows:

1. GUARANTEE. Guarantor absolutely, unconditionally and irrevocably guarantees to Owner that:

(a) if for any reason Contractor shall fail to make proper payment to Owner of any amounts from time to time due and payable by Contractor under the Contract, including, but not limited to, the payment of damages, Guarantor will pay to Owner such amount not paid by Contractor. Guarantor will make such payment within thirty (30) days of having received from Owner written notice of such failure and a demand for payment, such payment being the same as would have been received by Owner had such amount been duly paid by Contractor in accordance with the terms of the Contract.

3. ABSOLUTE OBLIGATION. The obligations of Guarantor under this Guaranty are absolute and without regard to lack of power or authority of Contractor to enter into the Contract or any other circumstances which might otherwise constitute a legal or equitable discharge of a surety or guarantor. Guarantor agrees that Owner and Contractor may modify or amend the Contract and that Owner may delay or extend the date on which any guaranteed obligation must be paid or performed, or release Contractor from any guaranteed obligation or waive any right thereunder, all without notice to or further assent by Guarantor, which shall remain bound by this Guaranty, notwithstanding any such act by Owner.

(d) the voluntary or involuntary liquidation, dissolution, sale or other disposition of all or substantially all of any of Contractor’s assets, the receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization of, or similar proceedings affecting Contractor or any of the assets of Contractor;

(e) the merger or consolidation of Contractor into or with any corporation or other entity, or Contractor’s loss of its separate corporate identity or its ceasing to be an affiliate of Guarantor;

(f) any action by Owner under the Contract granting indulgence or extension of time for payment to Contractor or any other surety except as so granted; or

4. LIMITATION OF LIABILITY. Notwithstanding anything to the contrary contained herein, Guarantor’ obligations to perform in accordance with Article 1 hereof: (a) shall be subject to the same limitations as limit Contractor’s duty to perform under the Contract, and Guarantor

shall be entitled to assert the same rights, releases, indemnities, hold harmless provisions, insurance protection, and all limitations of liability including monetary limitations of liability against Owner hereunder as Contractor might assert against Owner under the Contract, (b) shall not expand or in any way exceed the obligations of Contractor under the Contract, and (c) shall not extend beyond expiry or termination of Contractor’s obligations under the Contract.

Guarantor waives promptness, diligence, presentment, demand of payment or enforcement and any other notice with respect to any of the guaranteed obligations and this Guaranty.

6. SUBROGATION RIGHTS. Any subrogation rights of Guarantor arising by reason of any payments made under this Guaranty shall be subordinate to the performance in full by Contractor of all obligations under the Contract, including, without limitation, payment in full of all amounts which may be owing by Contractor to Owner thereunder.

7. TERM. This Guaranty shall remain in full force and effect until the completion of Contractor’s obligations under the Contract.

8. ASSIGNMENT. This Guaranty shall inure to the benefit of Owner, its successors and permitted assigns and shall be binding upon Guarantor and its successors and permitted assigns.

Guarantor may not assign this Guaranty without the prior written consent of Owner, which may be withheld in Owner’s sole discretion.

9. REPRESENTATIONS AND WARRANTIES. Guarantor hereby represents, warrants and covenants that:

(a) entering into this Guaranty and performance hereunder (i) is not an event of default or otherwise contrary to any obligation by which Guarantor may be bound, and (ii) will not result in the creation or imposition of any lien upon any property of Guarantor;

(b) Guarantor is a corporation duly incorporated, validly existing and in good standing under the laws of Louisiana and is in good standing in each jurisdiction where the failure to be in good standing would materially and adversely affect its ability to perform its obligations under this Guaranty, and Guarantor will maintain its existence and remain in good standing under such laws;

11. EXERCISE OF REMEDIES. No single or partial exercise by Owner or its successors or assigns of any right or remedy shall preclude any further exercise thereof.

12. WAIVERS. No delay or omission to exercise any right or power of Owner shall impair any such right or power or shall be construed to be a waiver thereof.

15. GOVERNING LAW; CONSENT TO JURISDICTION. This Guaranty shall in all respects be governed by and construed in accordance with the laws of the State of North Carolina, without giving effect to any choice of law rules thereof which may direct the application of the laws of another jurisdiction.

Table 3.1.2-a FGD Purge Stream Characteristics (excluding 2-day surge events)

Table 3.1.2-b FGD Purge Stream Characteristics (excluding 2-day surge events)

The four *** Makeup Water Pumps (SSW) powered from Duke’s existing station auxiliary system are not included in the Unit 5 Scrubber Electric Power Consumption determination.

This Exhibit establishes conditions, parameters and methods for *** of Unit 6 *** guarantees established by the Agreement, corrected to the Base Performance Conditions identified in Section 7 of this Exhibit.

Unit 6 Net Output and Heat Rate will be tested, calculated and corrected based on the *** steam flow, identified in the Section 7. Main Steam Flow Capacity Testing will be at the ***.

Additionally, Performance Verification of the Steam Generator, Steam Turbine, and AQCS along with major plant equipment and systems is addressed.

Consumptive guarantees subject to Performance Liquidated Damages shall also be tested in accordance with this Exhibit and measured while simultaneously achieving Guaranteed Emission Limits and guaranteed gypsum quality.

Unit 6 will not exceed Permitted Emissions Limits as identified in Exhibit M, and measured in accordance with Table L-2.1 during Performance Testing. Emission Compliance Testing, including CEMS Certification testing, may occur prior to Substantial and Final Completion, with Guaranteed Emission Limits verified during Performance Testing of the Unit 6 using the certifiable CEMS (defined in Section 8.3).

If tuning or other adjustments to Unit 6 that may effect emissions occur after non-CEMS monitored emission acceptance and prior to Substantial and/or Final Completion, the Owner may require re-testing of emission compliance of non-CEMS monitored parameters to verify that tuning has not violated emission compliance.

Guaranteed Emission Limits and Guaranteed Removal (%) found in Exhibit M are Make Right Performance Guarantees.

Table L-2 summarizes the Performance Testing and Equipment Verification Program. The purpose of the Performance Test and Equipment Verification Program is fivefold:

The Agreement contains specific information concerning guarantees, results, re-testing, schedule, remedies, liquidated damages and warranties, and is not addressed in this Performance Testing Exhibit.

The Contractor’s *** Performance Guarantees are based on the guaranteed performance of the Owner Equipment. Plant performance test results shall be corrected for *** shortfalls that are not attributable to ***. It will be the Contractor’s responsibility to test, document and verify any such claimed performance shortfall.

The initial Performance Testing is used to satisfy the Minimum Performance Guarantee. This Test shall be satisfied by the same methods as the Unit 6 Performance Test methodology, except where a substitute test method is approved by the Owner.

A substitute test using installed plant permanent instrumentation in lieu of calibrated temporary test instrumentation may be approved after Owner review. The pricing defined in Exhibit I is based on the Contractor using plant permanent instrumentation for the initial Performance Testing to satisfy the Minimum Performance Guarantee. Additional temporary high accuracy instrumentation will be used by Contractor for purposes of verifying compliance with the Guaranteed Performance.

The initial Performance Test may satisfy the requirement of the Performance Guarantees if preformed in accordance with Section 6. of this Exhibit.

A Test Contractor approved by the Owner, shall conduct the Unit 6 Performance Test, Steam Generator and Steam Turbine Performance Test, and compile the Plant Baseline Data. The Contractor and the Test Contractor may share the responsibility for the Major Equipment Verification as outlined in Table L-2.

The Test Contractor shall be responsible for the Performance Test Plan (PTP) , test instrumentation including calibration and set up, pre and post test uncertainty analysis, conduct of the testing, data acquisition, data reduction, post test calculations, and test report for Unit 6 Performance Testing, Steam Generator and Steam Turbine Testing, Plant Baseline Data and Major Equipment Verification (except where excluded in Table L-2).

The Contractor will submit *** days prior to commencement of the Performance Test a complete detailed Performance Test Plan (PTP) mutually approved by Owner, Test Contractor, Contractor and Owner Equipment Contractor’s. The PTP will constitute an agreement for the Performance Testing by the Parties to the test. Differences between the Test Procedures or methods contained in/or developed in accordance with the PTP and the respective Agreements or established industry test codes are by mutual agreement of the Parties to the test, as approved in the PTP.

The PTP form and contents shall specifically meet the requirements of ASME PTC 46 – 1996, Section 3.2 “Test Plan”, where ASME Code Testing procedures are being applied. The actual test methods and corrections for each test shall be in accordance with Codes identified in Table L-2.

*** tolerances or uncertainties shall be applied to any Performance Test results for the satisfaction of Unit 6 Performance Guarantees, or Steam Generator or Steam Turbine Tests.

Pre-Test uncertainties (for ASME Code Tests) will be calculated in accordance with applicable ASME Codes, and shall not exceed ASME PTC requirements for the applicable Code Test. Post test field verifications will be performed on instruments measuring parameters where there is no redundancy or for which the data is questionable.

Degradation shall be applied to the Unit 6 *** Tests, in accordance with Owner Equipment guarantees. An *** test in accordance with *** requirements, shall be performed on the steam turbine by the Test Contractor as soon as practical after startup, and prior to the ***. Degradation attributed to the *** shall be based on enthalpy drop test results in accordance with Steam Turbine Generator guarantees.

Corrections to test results due to *** that are attributable to Contractor’s actions shall not be applied. This includes both equipment scope and schedule effects.

Performance Testing involves set-up, testing, measurements and data collection, subsequent calculations and corrections. A series of three (3) individual Test Runs meeting the Code requirements for duration (no less than 2 hours each), shall be performed at the test conditions, which Unit 6 is subject to at the time of the testing. Test operational and data stability requirements set forth in ASME Codes shall be met.

Results of the three (3) Test Runs shall be corrected to Base Performance Conditions and averaged for comparison. The Unit 6 Performance Test will be compared to the Performance Guarantee values. The Steam Generator and Steam Turbine will be corrected to Owner Equipment Contract conditions and compared to contract values.

Demonstration of the Steam Generator and Steam Turbine performance will require the Test Contractor to perform measurement/correction methodology required by the governing ASME PTC.

Contractor shall provide all required ASME PTC 46, PTC 4 and PTC 6 correction data. At a minimum, raw source data for curves or correction curve equations shall be supplied. Curves may be additionally supplied as well, but priority of test correction source will be, in order of

preference; Manufacturer provided source data or curve equations, best fit equations of Manufacturer provided data or curves, visual reads of Manufacturer provided data or curves, and Contractor supplied data, curves, and equations. Contractor shall submit all correction calculations, correction data and any thermal models for review and approval 60 days prior to commencement of testing.

Instrument calibration shall meet ASME PTC Code requirements. Test Contractor shall submit all instrument calibration data to the Contractor and Owner for review prior to the commencement of the Performance Test. Flow devices meeting the requirements set forth by ASME Code to measure primary parameters and variables need not undergo inspection following the performance test if the devices have not experienced conditions that would violate their integrity. Such conditions include steam blows and chemical cleaning.

The Contractor will have the responsibility for providing all test instrumentation and equipment, whether temporary or permanently installed. Instrumentation shall meet the requirements of the applicable ASME PTC Code, in order that the calculated pre test uncertainty does not exceed ASME Code requirements. Primary condensate flow instrumentation shall be supplied and calibrated in accordance with ASME PTC 6 – 2004, and shall remain the property of the Owner after the completion of Performance Testing.

Test runs are not required to be continuous, but shall occur within the same 72 hour period, in order to assure that the Unit 6 configuration and the test conditions are relatively similar. The Owner may waive this requirement.

The Unit 6 Performance Test will be in accordance with ASME PTC 46-1996 “Performance Code on Overall Plant Performance”, except where modified by the Contract, or by mutual agreement by the Parties to the Test.

For a coal fired unit, this will require determination of steam generator efficiency, in order to calculate primary heat input, in accordance with ASME PTC 4 - 1998, Energy Balance method, except as noted in this Exhibit.

The Performance Guarantee applies to the testing of Unit 6. Common loads shared with Unit 5 will be proportioned to each Unit.

The electrical terminal point of the Unit 6 Performance Guarantee is as measured at the high side of the main step up transformers. Transformer losses (main step up and aux) due to corrections to Base Performance Conditions will be included as part of the post test corrections.

Material Handling auxiliary load terminal point will be considered the inlet (delivery point from truck or rail carrier) of the coal, limestone and lime unloading hoppers or transport piping. For gypsum and ash, the terminal point will be the ash silos and gypsum storage pile.

The Unit 6 Net Output and Heat Rate Guarantee shall include all auxiliary loads, including pumps, fans, motors, heaters, air conditioning, lighting, material handling and miscellaneous equipment that are required to operate the equipment in a normal plant configuration.

The Unit 6 Net Output and Heat Rate Guarantees are based on the electrical auxiliary loads for major JPDA equipment as listed in Table L-2.2. The Performance Guarantees will be revised to incorporate changes in any of the Table L-2.2 values due to final equipment selections.

The auxiliary load methodology for the Unit 6 Performance Test will be based on operation of Unit 6 during the Base Performance Condition (summer day). As part of the PTP, the Contractor will submit, for approval, a load list, indicating the test operating status of all plant electrical equipment greater than 2 hp (valve motor operators need not be accounted for): The following is the type of operation that is expected:

Material handling, water treatment and other loads of a cycling nature shall be characterized prior to the Unit 6 Performance Test. The Contractor will submit as part of the PTP, procedures for the determination of these cycling loads, for Owner approval. Fuel, Ash, Limestone, Lime, Gypsum, make up and waste water handling (except AQCS purge stream treatment) auxiliary loads will be determined based on testing done prior to the Unit 6 Performance Testing. The methodology shall also contain procedures and calculations for the proportioning of auxiliary loads to Unit 6 and the Unit 5 Scrubber.

Auxiliary loads for major Owner Equipment will be individually measured for determining satisfaction of Owner Equipment Contract guarantees.

Preliminary testing and results calculations shall occur prior to commencement of Unit 6 Performance Testing (this testing is not required for Substantial Completion). Results shall be submitted to the Owner and approved prior to Unit 6 Performance Testing.

Testing will determine the kw-hr consumed per unit of material, for correction to the plant auxiliary loads measured. Where appropriate, and approved by the Owner, operation of cycling loads during the test can be substituted. For example, coal reclaim auxiliary load could be determined by characterization test or by returning the coal silo to pre test levels prior to the end of the test runs.

During the Unit 6 Performance Test, Unit 6 will be aligned and operated in the normal plant configuration – as approved by the Owner, with regards to mechanical and electrical components and systems. All steam and water drains and traps will be aligned for safe system operation.

The DCS will be in automatic operation, except where approved by the Owner. Setpoints, system limits, alarms and trips will be in normal plant configuration and will not be deviated from, for the purpose of the Unit 6 Performance Test.

As part of Unit 6 Performance Testing, a *** will be performed to assure that Unit 6 can achieve this steam flow operating condition on a continuous basis. Although not specifically addressed in ASME PTC 46, the Main Steam Flow Capacity will be verified using the ASME PTC 46 governed Unit 6 Performance Test instrumentation and calibration methods, except where approved by the Owner.

Contractor shall report test results for the *** and the corresponding net electrical output (which is not guaranteed for this test). Net electrical output shall be corrected to Base Performance Conditions for power factor, and wet bulb.

Steam Turbine Test (Full Test) in accordance with ASME PTC 6 – 2004 will be required to demonstrate the steam turbine performance. Likewise, the performance of the Steam Generator will be demonstrated using ASME PTC 4—1998. These Tests shall be in accordance with the subject Owner Equipment Contracts and the mutually agreed to test procedures. Test procedures shall also provide for demonstration of individual auxiliary loads for Steam Turbine, Steam Generator and AQCS. See Table L-2 of this Exhibit.

The Contractor shall provide a complete report in accordance with ASME PTC 46 (PTC 4 and 6 for the Steam Generator and Steam Turbine respectively), and will be submitted within the time specified in the Agreement. A preliminary report of results shall be submitted within the time specified in the Agreement. The report shall be submitted in both electronic and paper format. Final report contents shall be defined in the Performance Test Plan. This shall include, but not be limited to:

Unit 6 Performance Guarantees are based on the following reference conditions. Test results for the Unit 6 Performance Testing will be corrected to these conditions as detailed in the Performance Test Plan:

The Contractor shall report the performance of major equipment, using data collected either during Unit 6 Performance Testing or individual Equipment Verification Testing. This testing is not required to be in strict accordance with applicable Test Codes referenced in Manufacturer contracts, but shall be of sufficient accuracy to give indication of the equipment performance. The results shall be corrected to Manufacturer contract conditions as part of the Test Report. The Contractor shall supply all raw data and calculations as part of the Test Report.

The Owner will use these reports to make a determination concerning the need for further detailed Code testing of equipment, outside of the Contractor’s scope.

These tests can be run concurrently with the Unit 6 Performance Test, where appropriate:

The Contractor shall report the overall Unit 6 baseline performance data for key operating parameters (to be identified with Owner agreement, in the Performance Test Plan) based on a combination of data taken during the Unit 6 Performance Test, Steam Generator and Steam Turbine Performance Test and DCS collected data. The goal is to establish initial Plant Baseline Data for comparison for future operation.

The basis of the report shall be uncorrected averaged data from both the DCS and temporary performance test instrumentation from one of the Unit 6 Performance Testing Test Runs selected by the Owner.

Once Mechanical Completion has occurred and Unit 6 is sufficiently complete so that all systems are capable of safe operation in accordance with applicable Laws, Good Practices and the Project Manuals, Contractor shall test Unit 6 in accordance with the requirements of applicable Government Approvals, applicable regulations and Exhibit M to verify compliance with the Permitted Emission Limits and to certify the Part 75 CEMS systems (the “Emissions Compliance Test”). The Emissions Compliance Test shall be undertaken by the Contractor in compliance with all federal, state, local, and Contract requirements; including schedule.

The Emissions Compliance Test shall be completed successfully prior to initiation of Performance Testing. Stack emissions, including opacity, will be measured for Unit 6 during the Performance Test. sulfur dioxide (SO₂), nitrogen oxide (NO_X), and mercury (Hg) will be verified using the Unit 6 “certifiable” CEMS or by a certified leased CEM system. A certifiable CEMS is defined as a CEMS that has been installed, calibrated, tested (40 CFR, Part 75 Certification Test) and maintained in accordance with the requirements of the air permit and appropriate regulatory requirements. The “certifiable” CEMS are not required to have received formal regulatory approval. Opacity will be verified using the Unit “certifiable” continuous opacity monitoring system (COMS).

The Contractor shall develop a schedule for providing the Owner necessary forms, data and reports well in advance of regulatory required Owner notifications and submittals. Contractor shall prepare forms, data and reports in accordance with Applicable Permits and regulatory requirements.

The Contractor shall perform the following tests prior to, Final Completion. Contractor shall submit test procedures, measurement points, acceptance criteria and operating parameters for Owner approval, *** prior to the commencement of testing.
