possible the updated *** to the extent that doing so will not adversely impact the ability of Owner 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 Cash Flow payment and other payments due under this Agreement

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

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.

8.2. Change Order Pricing. All Change Orders will be developed on an open book basis, and the Owner shall have the right to review the detailed cost estimates and assumptions for the Work to be included in the
Change Order. For each Change Order, the Parties may agree to have Contractor perform the Work under such Change Order in accordance with any of the pricing categories set forth in this Agreement, or a combination thereof, and, if the Parties are
unable to agree on a pricing category under which such Work shall be performed, such Work shall be performed ***. All Contingency will be negotiated on a case by case basis, depending upon the risks associated with the Change Order Work.

8.3 Change Order Billing. All Change Orders shall be Invoiced and paid in accordance with the payment terms set forth in the Change Order.



|9. | FORCE MAJEURE
|-- | -------------

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 an equitable adjustment to: ***, 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 Section 23.5. 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. | INSPECTION: PERFORMANCE TESTING: PERFORMANCE GUARANTEES
|--- | -------------------------------------------------------

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



40



---

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 or Early Completion Bonus. 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



41



---

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.

43



---

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)

|12. | DELAY AND PERFORMANCE LIQUIDATED DAMAGES; EARLY COMPLETION BONUS
|--- | ----------------------------------------------------------------

12.1 Delay Liquidated Damages.

(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



44



---

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 Unit 5 Tie-In Commencement Date, (ii) Contractor does not complete the successful Tie-In of the Unit
5 Scrubber by the Guaranteed Unit 5 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 Unit 5 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 Unit 5 Tie-In Commencement Date that Unit 5 Scrubber Tie-In does not commence,
each Day after the Guaranteed Unit 5 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 Unit 5 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.

12.2 Performance Liquidated Damages.

(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



45



---

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 thirty-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 thirty-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. | WARRANTY
|--- | --------

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



46



---

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. Unless otherwise mutually agreed in writing for a particular piece of Equipment, Contractor
warrants that all 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 that is the earlier of: (a) *** from the date Substantial
Completion of Unit 6 or the Unit 5 Scrubber is achieved or (b) for items of Engineered Equipment provided by a Subcontractor, the expiration of such Engineered Equipment Subcontractor warranty; provided that, ***. If Contractor fails to
so notify Owner, Contractor shall be responsible for the full *** warranty obligation on such ***. Except for Equipment noted in Section 13.2(b) above, 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 at no additional cost to Owner, 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.



47



---

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 (except as delineated in Section 13.2), 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,



48



---

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. | INDEMNIFICATION
|--- | ---------------

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

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. Notwithstanding
anything to the contrary, Contractors obligations under this Section 14.3 shall not apply to the Owner Equipment.

14.4
Indemnity Procedures for Third Party Claims.

(a) In the event of a Third Party Claim with respect to which an
Indemnified Party has a claim for indemnification under this Article, then the Indemnified Party must notify the indemnifying Party thereof in writing of the existence of such Third Party Claim and must deliver copies of any documents served on the
Indemnified Party with respect to such Third Party Claim; provided, however, that any failure to notify the indemnifying Party or deliver such copies will not relieve the indemnifying Party from any obligation hereunder unless (and
then solely to the extent that) the indemnifying Party is materially prejudiced by such failure.

(b) The indemnifying Party
shall have the right to conduct and control, through counsel of its own choosing, reasonably acceptable to the Indemnified Party, any Third Party Claim; provided, however, that (i) if requested by the Indemnified Party, the
indemnifying Party provides the Indemnified Party with evidence reasonably acceptable to the Indemnified Party that the indemnifying Party will have the financial resources to defend against the Third Party Claim and fulfill its indemnification
obligations hereunder, (ii) the Indemnified Party may, at its election, participate in the defense thereof at its sole cost and expense and (iii) if (A) the indemnifying Party shall fail to defend any Third Party Claim, (B) the
Parties mutually agree in writing to allow the Indemnified Party to assume the defense of such Third Party Claim and forego any indemnity claimed under this Article, (C) in the reasonable opinion of legal counsel for the Indemnified Party, such
Third Party Claim involves the potential imposition of criminal liability on the Indemnified Party, its directors, officers, employees or agents, (D) in the reasonable opinion of legal counsel for the Indemnified Party, the Third Party Claim
involves, or is likely to involve, any claim by any Government Authority or (E) in the reasonable opinion of legal counsel for the Indemnified Party, an actual or potential conflict of interest exists where it is advisable for such Indemnified
Party to be represented by separate counsel, then the Indemnified Party shall be entitled to control and assume responsibility for the defense of such Third Party Claim, at the cost and expense of the indemnified Party. The indemnifying Party may,
in any event, participate in such proceedings at its own cost and expense.



51



---

(c) The indemnifying Party, in the defense of any such litigation, other proceeding or
other claim, shall have the right in its sole discretion to settle such Third Party Claim only if (i) such settlement involves only the payment of money and execution of appropriate releases of the Indemnified Party and its Affiliates,
(ii) there is no finding or admission of any violation of Law, and (iii) the Indemnified Party or its Affiliates will have no liability with respect to such compromise or settlement. Otherwise, no such Third Party Claim shall be settled or
agreed to without the prior written consent of the Indemnified Party. The Indemnified Party and the indemnifying Party shall fully cooperate in good faith in connection with such defense and shall cause their legal counsel, accountants and
affiliates to do so, and shall make available to the other Party all relevant books, records, and information (in such Partys control) during normal business hours, and shall furnish to each other such other assistance as the other Party may
reasonably require in connection with such defense, including making employees of the Indemnified Party available to testify and assist others in testifying in any such proceedings.

Contractor (including its Affiliates) and its Subcontractors on such Builders Risk insurance policy except for any claims or matters in which the Equipment warranty or the Services warranty provided by Contractor or any Subcontractor hereunder
are involved. It is further agreed that Owner may elect to self-insure this risk. In the event that Owner elects to self-insure the Builders Risk, Owner shall waive its right to recover the cost to repair or replace such loss or damage from
Contractor (including its Affiliates) and its Subcontractors in excess of the deductible and to the extent that coverage would have been available had Owner obtained the foregoing Builders Risk insurance policy. Should a loss be sustained at
the Site and in the course of construction to property that is to be incorporated into the Project, Contractor shall replace or repair such loss or damage in accordance with the terms of this Agreement, and Contractor shall be reimbursed for all
such costs plus the cost of extended overhead (including for home office costs and Field Non-Manual and procurement costs). Contractor shall act on behalf of Owner, at Owners request, for the purpose of adjusting any loss to Owners

15.3 General Requirements:

(a) The provisions of this Article do not modify or change any responsibility of Contractor or its Subcontractors as stated elsewhere in
this Agreement. Owner assumes no responsibility for the solvency of any insurer to settle any claim. The insurance requirements herein are separate and apart from and in no way limit Contractors Indemnity as stated in Section 14 of
this Agreement. Anything herein to the contrary notwithstanding, the liabilities of Contractor under this Agreement shall survive and not be terminated, reduced or otherwise limited by any expiration or termination of insurance coverages. Neither
approval nor failure to disapprove insurance furnished by Contractor shall relieve Contractor from responsibility to provide insurance as required by this Agreement. No policy shall contain an exclusion that it would not respond to cover losses for
damages to any Owner pre-existing property. All policies of insurance required hereunder shall be endorsed or shall otherwise provide that Contractors insurance shall be primary with respect to Contractors acts or omissions and not be in
excess of, or contributing with, any insurance maintained by Owner (other than any Builders Risk as provided in this Agreement). Owner and its successors and assigns (including the Financial Institutions) shall be named as additional insureds for
their imputed liability as a result of Contractors negligent operations hereunder, using ISO additional insured (CG 20 10) or equivalent, under all policies of liability insurance to be maintained by Contractor (except Workers
Compensation insurance and Professional Liability). The liability policies of insurance shall be endorsed or shall otherwise include



55



---

severability of interest or cross liability clause. The policies set forth in this Article shall each contain a provision that coverages afforded under the
policies will not be cancelled, renewed or materially modified unless at least sixty (60) Days prior written notice via certified United States mail has been given to Contractor and Owner or to any other entities as herein or hereinafter
required, at the address so provided to the insurance company. All insurance required by this Article shall be provided by companies that have (and shall maintain during the applicable policy period) an AM Best Rating of A- VII or higher.
Certificates shall be provided to Owner on *** industry standard ACORD forms showing such coverage in full force and effect shall be delivered to Owner within thirty (30) Days of the *** Date, *** within ten (10) Days of each policy
renewal or change and from time to time thereafter, as may be requested by Owner. All policies shall include waivers of any right of subrogation of the insurers there under against Owner and its successors and assigns (including the Financial
Institutions) using standard ISO forms or equivalent. The existence of any self-insured retentions (SIRS) over which the required policies apply must be disclosed to and approved by Owner. Contractor shall provide copies of CCIP placement and
renewal policies and all endorsements *** to the Owner not later than sixty (60) Days following placement or renewal.

(b) Contractor shall comply with the conditions stipulated in each of the insurance policies. None of the insurance coverage required hereunder shall be on claims-made forms, except Professional Liability. Coverage amounts must
be fully available to any obligations under this Agreement (not eroded by any other project or agreement) and apply on an annual basis. CCIP provisions for excluding Subcontractors must be disclosed and approved by Owner in writing prior to CCIP
effective date.

(c) If any of the insurance required under this Article (other than project-specific insurance) shall be
directly or indirectly depleted by *** or more (whether due to payment of insurance proceeds, creation of a reserve or otherwise), Contractor shall obtain from the insurer a reinstatement option, if commercially available at a cost comparable to the
original policy cost, to each such policy at least equal to the depleted amount. *** shall bear the cost of such option (including the cost associated with the reinstatement) ***. Contractor shall cause such insurer to send to Owner a notice of such
reinstatement and a copy of the reinstated policy related thereto upon Owner exercising and payment for the reinstatement.

(d) The insurance policies required by this Article shall allow for occupancy and utilization of the Facility, the Equipment and the Site by Owner, its Affiliates and any person reasonably permitted access thereto by Owner, including any
representatives of the Financial Institutions.

(e) During the time any Subcontractor is engaged to perform any Service
under this Agreement, Contractor shall obtain a certificate of insurance from such Subcontractor evidencing that such Subcontractor has obtained, and will maintain and keep in full force and effect (required only for off-Site Work if covered by
CCIP, otherwise for all Subcontractor Work), Workers Compensation in statutory amounts, Employers Liability, Commercial General Liability, Automobile Insurance and all other policies reasonably necessary to perform such Service with
adequate coverages and in such amounts in accordance with Contractors normal practices and consistent with Good



56



---

Industry Practices, and provide Owner with evidence acceptable to Owner of such coverage, or Contractor shall maintain such coverage under its own insurance
policies or CCIP. Contractor shall ensure that all Subcontractors obtain and maintain prudent insurance coverages. All Subcontractor coverages shall waive subrogation rights against Owner and Contractor, and shall name Owner and Contractor as
additional insured (except Workers Compensation and Professional Liability).

(f) Any certificates of renewal with respect
to any insurance policy required to be maintained by Contractor hereunder shall be delivered to Owner promptly after renewal. Contractor shall insure that the insurer shall submit a copy of all receipts for premiums paid to Owner promptly after
payment of such premiums. Contractor shall be solely responsible for the timely payment in full of premiums for all insurance required of it hereunder. Should Contractor fail to provide or maintain any insurance required hereunder, Owner shall have
the right, but not the obligation, to provide or maintain any such insurance, and to deduct the cost thereof from any amounts due and payable to Contractor, or, in the event there are no such amounts due and payable, Contractor shall reimburse Owner
for such costs on demand. Contractor shall not unreasonably refuse to cooperate or to take any actions requested or necessary to prosecute any claims under any insurance policy required to be maintained by Contractor hereunder.

(g) With respect to ocean marine shipments, Contractor shall obtain at least fifteen (15) Days prior to any such shipment, cargo
insurance covering all risks of loss or damage to property shipped, components of property shipped, or items contained in or shipped in or with the property shipped. This coverage is to be written on a replacement cost basis and in the
full insurable value of these items, including packing and freight charges plus duties and fees. The coverage required by this paragraph shall continue in effect until appropriate coverage commences at the Site.

15.4 Insurance Costs and Assumptions. ***. For any Change Orders, additional CCIP costs, if any, shall be allocated to such Change Orders in
proportion and as part of the same pricing components as set forth in (i) through (iv) above.

Moodys Investor Services, Inc.) and permits presentation at a bank located in Charlotte, NC, Atlanta, GA, or New York, NY. If at any time the Standby Letter of Credit fails to meet the foregoing conditions, Contractor shall replace the
outstanding Standby Letter of Credit with a Standby Letter of Credit that meets the foregoing conditions. Contractor shall ensure that the Standby Letter of Credit shall be renewed or replaced on an annual basis and shall remain in full force and
outstanding until the expiration of the Warranty Period, as such period may be extended pursuant to Section 13.3. If Contractor fails to renew or replace the Standby Letter of Credit at least thirty (30) Days prior to the expiration
thereof, then, in the sole and absolute discretion of Owner, Owner shall be entitled to draw and retain until the end of the Warranty Period the full amount of such Standby Letter of Credit. Such retained amount, less any amount offset against such
retained amount for claims, shall be returned to Contractor promptly upon expiration of the Warranty Period.

(b) Contractor
shall cause the Standby Letter of Credit to be amended or replaced *** set forth in the Letter of Credit Value Chart attached as Exhibit J-3 (the Letter of Credit Value Chart) so that the amount of such
amended or replacement Standby Letter of Credit is revised to be equal to the amount set forth in the Letter of Credit Value Chart attached as Exhibit J-3; *** results in a revision to the Cash Flow Plan or any component thereof, or in the
event of a *** Change Order (or series of Change Orders) that increases or decreases, cumulatively, the *** Contract Price by more than ***, Owner, in its reasonable discretion, shall be entitled to make an equitable adjustment to the Letter of
Credit Value Chart to take into account such event, in which case Contractor, *** shall amend, replace or supplement the then-outstanding Standby Letter of Credit to reflect the adjustment made to the Letter of Credit Value Chart. ***, Owner shall
not be obligated to make further Invoice payments, approve any such Change Order or modify the Schedule until Contractor shall have provided Owner with such amended, replacement or supplemental Standby Letter of Credit.

(c) Contractor shall Invoice Owner on a quarterly basis for the fees charged by the issuing financial institution for the issuance of the
Standby Letter of Credit (including any amendment or replacement thereto) from the Effective Date through the Warranty Period, but without any administrative charges or Contractor profit added to such financial institution fees. For any equitable
increase to the Letter of Credit Value Chart after the Effective Date, Owner shall pay the then-current fees charged by the issuing institution for such amendment, replacement or supplement. Contractor shall provide such documentation and materials
as Owner may reasonably require to substantiate the *** Letter of Credit (including the fees *** for any amendment, replacement or supplement thereto).

16.3 Cooperation with Owner Financing.

(a) Contractor shall promptly provide to
Owner (i) all cooperation that Owner reasonably requests to make presentations to potential Financial Institutions and their

consultants and representatives and to respond to any questions or requirements asked or imposed by any Financial Institutions, including any requests for
financial information relating to Contractor, and (ii) all cooperation that Owner reasonably requests with respect to the Financial Institutions and their consultants and representatives, including developing and providing information regarding
the Project (if available to Contractor) and this Agreement. Contractor shall provide the Financial Institutions with reasonable access to, and will permit them to review, the Documentation. In addition, Contractor shall provide the Financial
Institutions with (A) the right to receive and render performance and to give reasonable time to cure defaults by Owner, on behalf of Owner, under this Agreement, (B) reasonable access to the Site and any other location where Services,
including testing, are performed for the purposes of inspecting the Equipment and the Owner Equipment, provided that any such inspection does not unreasonably interfere with or delay Contractors performance of the Services and (C) such
access to documentation in relation to this Agreement or the Work at such times as Owner shall reasonably request. For any additional time required by any Financial Institution to cure any defaults of Owner hereunder, which defaults interfere in
Contractors ability to perform the Services, Contractor shall be entitled to an equitable adjustment in the Schedule in accordance with Article 8.

(b) Contractor hereby consents to the collateral assignment of this Agreement to the Financial Institutions. Contractor also shall enter
into a consent to assignment with the Financial Institutions regarding this Agreement which shall contain provisions that are typically provided to financial institutions in similar project financing, including the right to render and receive
performance under this Agreement, and giving the Financial Institutions copies of notices delivered to Owner under this Agreement. Owner will be entitled to assign, and Contractor shall ensure that the relevant instruments permit the assignment of,
the benefit of any parental guarantee, Standby Letter of Credit or other financial instrument at any time to the Financial Institutions without the consent of Contractor or the issuer of such parental guarantee, Standby Letter of Credit or other
financial instrument being required.

|25. | QUALIFICATIONS AND PROTECTION OF ASSIGNED PERSONNEL
|--- | ---------------------------------------------------

25.1 Contractors Personnel. Contractor shall comply in all respects with all applicable labor and immigration Laws that may impact Contractors Work under this Agreement, including the Immigration Reform and Control Act of
1986 and Form I-9 requirements. Without limiting the generality of the foregoing, Contractor shall perform all required employment eligibility and verification checks and maintain all required employment records. Contractor acknowledges and agrees
that it is responsible for conducting adequate screening of its employees and agents prior to starting the Work. By providing an employee or Subcontractor under this Agreement, Contractor warrants and represents that it has completed the screening
measures with respect to such employee or Subcontractor and that such screening measures did not reveal any information that could adversely affect such employees or Subcontractors suitability for employment or engagement by Contractor
or competence or ability to perform duties under this Agreement. If in doubt whether a suitability, competence or ability concern exists, Contractor shall discuss with Owner the relevant facts and Owner will determine, in its sole discretion,
whether such Person should be allowed to perform the Work. Owner, in its sole discretion, shall have the option of barring from the Site any person whom Owner determines does not meet the qualification requirements set forth above. In all
circumstances, Contractor shall ensure that the substance and manner of any and all screening measures performed by Contractor pursuant to this Section conform fully to applicable Law. Contractor shall supervise, coordinate and direct the Work using
Contractors best skill, judgment and attention. Owner shall have the right to bar from the Site any Person employed or engaged by Contractor or Subcontractor who engages in misconduct or is incompetent or negligent while on the Site or while
performing the Services, or whom Owner has previously terminated for cause or otherwise dismissed or barred from the Site. Upon request of Owner, Contractor shall immediately remove those Persons to whom Owner objects from the Site and shall not
allow the further performance of the Services by those Persons. In addition, in the event that Contractor learns of any such misconduct, incompetence or negligence independent of Owners objection, Contractor shall remove such Persons from the
Site, shall not allow any further performance of the Services by such Persons and shall promptly notify Owner of such misconduct, incompetence or negligence and the actions taken by Contractor as a result thereof. In either such event, any cost for
replacement of such Persons shall be considered part of the Contract Price and shall be allocated to the pricing component for which the Work is being performed.

25.2 Drug and Alcohol Testing. Neither Contractor nor its Subcontractors shall in any way use, possess, or be under the influence of illegal drugs or controlled substances or consume or be under the influence
of alcoholic beverages during the performance of the Services. Any person (whether employed or retained by Contractor or any Subcontractor or otherwise) under the influence, or in possession of, alcohol, any illegal drug, or any controlled
substance, will be removed from the Site and, subject to Owners fitness for duty program requirements, shall be prevented from performing any future Services at the Site or elsewhere related to the Project. Contractor shall have in place a
drug testing program meeting the requirements of all applicable Laws and the Owners Drug and Alcohol Testing Policy (MICCS Substance Abuse Program, dated as of July, 2007) attached hereto as Exhibit N, as such policy may be updated by
Owner from time to time generally for its contractors, and shall furnish to Owner proof of compliance with



73



---

such regulations and policies, including a copy of Contractors drug and alcohol testing plan and an affidavit stating that Contractor is in compliance,
and will remain in compliance, with such regulations and policies for the duration of this Agreement. Upon request, and to the extent permitted by law, Contractor will furnish Owner copies of the records of employee drug and alcohol test results
required to be kept by Law. Contractor will indemnify and hold harmless Owner from any and all liability for (a) Contractors or any Subcontractors personnel who fail a drug or alcohol test given under any Government Authority
regulations, and (b) any claims made by a Contractors or Subcontractors employee resulting from removal from the Site as provided in this Article. If Contractor fails to comply with these regulations while performing under this
Agreement, such noncompliance will be deemed a breach of this Agreement, and Contractor shall be liable for such breach, as well as for all direct damages arising out of such noncompliance.

25.3 Training of Employees. 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.



|26. | RECORDS AND AUDIT
|--- | -----------------

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.



74



---

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, which records shall include an estimate of installed costs per component in
accordance with FERC accounting requirements, on a time and material, or reimbursement, basis in accordance with generally accepted accounting principles in the 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 *** claimed by Contractor for reimbursement or for any Work performed or provided by Contractor or its Subcontractors on a time and material basis or for any suspended, terminated, delayed or accelerated Services, *** third party
auditor 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 such costs as is reasonably necessary for Owner to verify such costs. However, Owner or its third party auditor shall have no right to audit records or books concerning the make-up of any agreed upon *** or fixed rates or
multipliers. As part of any such audit, Contractor shall provide data in the appropriate electronic native file format (i.e. Microsoft Word, Excel, Primavera, etc.) such that the data may be effectively sorted, summed, and evaluated.
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



75



---

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. | TAXES
|--- | -----

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 have the responsibility to 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. 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



76



---

(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 Equipment was 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;

(iii) The actual purchase prices of such Equipment;

(iv) The date of delivery to the Site of such Equipment;

(v) A description of the function of such Equipment; and

(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



77



---

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.

27.5 Tax Indemnification.

(a) Except in cases where such tax assessment is the result of the Gross 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. | DISPUTE RESOLUTION
|--- | ------------------

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



78



---

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.

28.2 Arbitration Proceedings.

(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 ***
initially designated *** 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.



79



---

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.

Electric Power Consumption:The 24-hour average electrical power consumption for the entire Unit 5
Scrubber shall not exceed *** kW based on the following:

***MCR; up to *** acfm at ***°F

3 spray levels operating;

*** lbs SO2/MMBtu coal;

***SO2 removal.

The guaranteed value has been developed using a listing of electric power users (documented in the Electric Load List for Unit 5), a methodology for
assigning duty factors to account for time of usage during the test period, and the portion of common equipment that applies to Unit 5. The methodology and associated duty factors may be modified to account for common equipment that only operates
part time (such as ball mills and belt filters) in a manner representative to the Unit 5 usage during the 24-hour period. Corrections may also be required, depending on final method of measurement that corrects for equipment and line losses not in
Contractors scope. The methodology and associated adjustments will be agreed upon and documented in the Performance Test Procedure.

Electric Power Consumption is a Liquidated Damages Performance Guarantee. Passing this consumption guarantee at one (1) condition is all that is required.

Limestone Consumption: The stoichiometric ratio as measured in representative gypsum samples for the Unit 5 Scrubber shall not exceed *** on a total plant basis while operating at steady state
conditions. This guarantee is predicated on *** wt% (minimum) of the limestone being reactive calcium carbonate equivalent. Reactive calcium carbonate shall be determined based on the total calcium carbonate in limestone corrected for unreactive
dolomitic limestone by removing a molar equivalent of calcium carbonate for each mole of magnesium in the limestone. The limestone will also meet the minimum requirements of the Alstom Power Limestone Reactivity Test [included with Alstom contract].
Calculation of the limestone consumption



---

will be based on the actual tested fuel firing rate, measured SO2inlet to the AQCS system, and the amount of excess limestone for Liquidated Damages purposes (if the stoichiometric ratio exceeds the guarantee) will be based on these values only and the excess stoichiometry above the guarantee value.
Gypsum is tested for stoichiometric ratio per the equation below that corrects for unreactive dolomitic limestone remaining in the gypsum by removing a molar equivalent of calcium for each mole of magnesium remaining in the byproduct. Results are to
be based on the average of 3 valid samples.

***

***

Liquid carryover: Liquid carryover shall not exceed 0.01 grains per acf as determined by hot wire anemometer
(developed by KLD) method using the Army Insecticide Monitoring System (AIMS-DC111 Probe) or agreed upon alternative method.

Gypsum Solids: Gypsum
solids product minimum oxidation fraction shall be no less than ***. Method of verification to be mutually agreed to by Owner and Contractor.

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.

1.2 Performance Test Program Philosophy

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

1.2.1 ASME Code Testing

Unit
Performance Testing - Confirm that individual Unit 6 Net *** guarantees contained in the Agreement are met, using ASME Performance Test Codes listed in Table L-2. If these values are not met, to establish the shortfall value for application of
remedies or damages addressed in the Agreement with the Contractor.



---

Steam Generator, Steam Turbine and AQCS Testing - Confirm the performance guarantees of
Owner Equipment are met, using Performance Test Codes listed in Table L-2. If these values are not met, to establish the shortfall value. These may be run concurrently with the Unit 6 Performance Test, where appropriate.

1.2.2 Non Code Testing

Major Equipment
Verification - Report the performance of major equipment, using data collected either during Unit 6 Performance Testing or individual Equipment Verification Testing. If performance guarantees are not met, to establish an estimate of the
shortfall value, for possible Code Testing.

Plant Baseline Data - Establish the overall Unit 6 Baseline Performance
Data for key operating parameters based on a combination of data taken during the Unit 6 Performance Test, Steam Generator and Steam Turbine Performance Test and DCS collected data.

Emissions Compliance Test and CEMS Certification  Perform emission compliance test and certify CEMS in accordance with Cliffside Air
Permit and referenced regulatory requirements.

1.3 Agreement Authority

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.

1.4 Performance of Owner Equipment

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

1.5 Substantial Completion Testing

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 performed in accordance with Section 6. of this Exhibit.

2.0 TEST RESPONSIBILITY

All testing described in this Exhibit is in Contractors scope of supply.

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).

3.0 PERFORMANCE TEST PLAN

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

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 Net ***. 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.

6.0 PERFORMANCE TESTING  ASME CODE TESTING

6.1 Test Runs and Corrections

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.

6.2 Instrument Calibration

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.

6.3 Test Equipment and Instruments

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.

6.4 Test Interruption

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.

6.5 Unit 6 Performance
Testing

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.

6.5.1 Electrical Terminal
Point of Guarantees  Unit 6

Performance Testing

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.

6.5.2 Unit 6 Performance Test Auxiliary Loads

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:

All normal interior lighting shall be energized.

EXHIBIT L-3

RELIABILITY TESTING



---

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, *** Days prior to the commencement of testing. Use of permanently installed plant instrumentation, in lieu of temporary test instrumentation, where appropriate, is
acceptable. Failure to satisfy Test Requirements due to Owner Furnished Equipment shall not be the Contractors responsibility. It will be the Contractors responsibility to test, document and verify any such claimed shortfall.

Emission limits provided in the EPC Agreement shall be satisfied at all times during the test.

Contractor shall submit a report of the results of each test required. This report will include the test procedure, measurement data and any calculations or other data required to support successful completion of this
test.

1.0 Part Load Test

(Four hour test)
 Contractor shall demonstrate Unit 6 will operate in a stable and reliable manner within equipment Manufacturers specifications.

2.0
Warm and Hot Start Tests

Contractor shall demonstrate that the Unit 6 is able to meet startup and synchronization requirements indicated in Table
L-3. The values in Table L-3 represent manufacturers predictions for the Owner Supplied Steam Generator, Steam Turbine and AQCS equipment. The Test Plan will state actual (but not guaranteed) values. Two warm and two hot start-up tests shall
be conducted.

3.0 Ramp Loading and Unloading Tests

Contractor shall demonstrate that Unit 6 is able to meet load ramp rates indicated in Table L-3 under automatic control. The values in Table L-3 represent manufacturers predictions for the Owner Supplied Steam Generator, Steam Turbine
and AQCS equipment. The Test Plan will state actual (but not guaranteed) values.

4.0 Load Change Tests

Contractor shall demonstrate that Unit 6 is able to respond to block load increases in accordance with requirements set forth in Table L-3. The values in Table L-3
represent manufacturers predictions for the Owner supplied Steam Generator, Steam Turbine and AQCS equipment. The Test Plan will state actual (but not guaranteed) values.

5.0 Governor Droop Tests

Contractor shall demonstrate using specific droop setting values that the turbine
control system responds as expected to specific changes in the speed (frequency) of the turbine-generator. Governor Droop Tests shall be specified by turbine-generator manufacturer and approved by Owner.



---

6.0 AVR Performance Tests

Contractor shall demonstrate the ability of automatic voltage regulation equipment to maintain stability under varying system frequency and voltage conditions within the limits of manufacturers specifications
and in accordance with Owners system standards,(to be provided later).

7.0 Auxiliary Trip Tests

Contractor shall demonstrate the capability of Unit 6 (with operator intervention) to automatically runback load upon the sudden loss of an operating auxiliary. Such test
shall demonstrate that Unit 6 is capable of maintaining expected available capacity with particular auxiliaries out of service. Test shall be conducted with Unit 6 running at maximum load achievable for the configuration prior to the trip. The tests
are the following:

Trip one induced draft fan

Trip one forced draft fan

Trip one primary air fan

Trip one pulverizer/feeder without initiation of standby

Trip one circulating water pump

Trip one condensate pump

Bypass
each closed feedwater heater, one at a time, with Unit 6 at VWO and normal pressure

8.0 Minimum Stable Load

Coal (twenty-four hour test firing coal)This test will identify minimum stable load which can be maintained indefinitely without fuel oil support using two
(2) mills. Minimum load on coal shall be no greater than 30% of BMCR for fuels as specified in Steam Generator Performance Guarantees.

9.0
Reliability Demonstration

Reliability Demonstration shall mean the operation of Unit 6 by Owner under the technical oversight of Contractor for a
period of *** after the Minimum Performance Guarantees with respect to Unit 6 have been met [but prior to Final Completion of Unit 6] by which the Contractor demonstrates to Owner that Unit 6 shall be capable of meeting the reliability criteria set
forth in this Exhibit. Notification requirements for this test are the same as Performance Test notification.

The average net electrical output during the
Reliability Demonstration shall be maintained and measured at the high side of the main step up transformer. The time



---

weighted average net electrical output of Unit 6 generated during the Reliability Demonstration period shall be utilized in determining the Demonstration
Results. Test results will only be corrected to ambient wet and dry bulb base reference conditions and power factor. This correction procedure may be done using an integrated plant computer model (such as Thermoflow Steam Master).

The acceptance criteria shall be an average of *** during the *** period. This criteria is based on the electrical auxiliary load for major *** equipment as listed in
Table L-2.2 of Exhibit L-2. The acceptance criteria will be revised to incorporate changes in any of the Table L-2.2 values due to final equipment selections. Operation is not limited to the ***. Fuels used during the test shall be as specified in
the Boiler Performance Guarantees.

If the test is aborted or acceptance criteria electrical demand is not maintained by the Owner, this period shall be
exempted from the test results, without extending the required test duration of ***. For example, if Owner cannot provide electrical demand for *** of the *** period, then *** will be used in the calculation of test results.
