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

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

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

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

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



36



---

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

(d) True Up of Contract Price.

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

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

7.3
Invoicing and Payments.

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



37



---

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

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

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

7.4 Cash Flow.

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

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



38



---

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

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

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

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

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

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

|8. | CHANGE ORDERS & PROVISIONAL SUMS
|-- | --------------------------------

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

(a) an increase or decrease in the quantity of any Work,

(b) any Work omitted,

(c) a Change in the character or quality or kind of any such Work,

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

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

(f) a Change in any specified sequence or timing of the Services.

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



| | (i) | the effect and impact, if any, that the Change would have, in Contractors reasonable judgment, on the Work, the Contract Price or the Schedule,
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | Contractors proposal for any necessary modifications to the Work, the Contract Price or the Schedule, and
| | ---- | ----------------------------------------------------------------------------------------------------------



| | (iii) | Contractors proposal for any necessary modifications to any other provisions of this Agreement, including the Specifications, the Milestones, the Milestone Payments or the
Performance Guarantees.
| | ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

---

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

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

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

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

|9. | 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 ***, and (b) the Contract Price; provided, that Contractor shall *** on Change
Orders which result from an event of Force Majeure.

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

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



|10. | 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



42



---

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

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

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



43



---

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

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

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

|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 Materials, Changes in Law, or as otherwise contemplated
in this Agreement), and, accordingly, if Contractor does not achieve Substantial Completion of Unit 6 by that date, subject to Section 12.1(c)below, Owners sole and exclusive remedy for such delay shall be to recover from
Contractor as liquidated damages, and not as a penalty, the Delay Liquidated Damages for each Day that Substantial Completion of Unit 6 is delayed beyond the Guaranteed Substantial Completion Date for Unit 6; provided, that in no event shall
the aggregate Delay Liquidated Damages for Unit 6 exceed its Delay Liquidated Damages Cap.

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



47



---

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

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

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 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.



48



---

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

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

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



|13. | 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
professional knowledge and judgment. For Unit 6 and the Unit 5 Scrubber, if any portion of the Services fails to comply with this warranty obligation and Contractor is so notified in writing prior to *** after the respective Substantial Completion
Date (the Services Warranty Period), Contractor will promptly re-perform such portion of the Services without additional compensation from Owner or, if re-performance is impossible or commercially impracticable, Owner and
Contractor shall meet and discuss in good faith an equitable way to resolve such matter in order to place Owner in as good a position as Owner would have been in had there been no such breach of the warranty obligation. If the Parties are unable to
resolve such matter in a manner reasonably acceptable to both Parties, either Party may initiate the Dispute resolution procedures set forth in Article 28.

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



49



---

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

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

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

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

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

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

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

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

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

(ii) any and all claims, demands or causes of action of every kind and character by any Person and all damages, liabilities, losses, costs

| | (c) | any prohibited assignment by Contractor of this Agreement.
| | --- | ----------------------------------------------------------

14.2 Owners Indemnity. Owner shall indemnify and hold harmless Contractor, its parents and Affiliates and their respective partners, shareholders, members, agents, employees, officers, directors, and lenders (collectively, the

| | (b) | any prohibited assignment of this Agreement by Owner, or
| | --- | --------------------------------------------------------

| | --- | -------------------------------------

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.

(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.

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 or retention amount 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

15.6 General Requirements.

The provisions of this Article 15 do not modify or change any responsibility of Contractor or any of 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.

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 a 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 or Owner approved form showing such coverage in full force and effect shall be delivered to Owner
within thirty (30) Days of the Effective 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. Owner 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 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, Contractor and all covered Subcontractors 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.

|--- | ----------------------

16.1 Parental
Guarantee. The obligations of Contractor under this Agreement shall be secured by a Guarantee in the form of Exhibit J-1 attached hereto and executed and delivered by the Guarantor. Contractor hereby represents and warrants that Guarantor
is ***. From the Effective Date until Final Completion of each Unit 6 and the Unit 5 Scrubber, Contractor shall, upon request of Owner, cause Guarantor to deliver to Owner (a) within *** Days following the end of each fiscal year, a copy of
Guarantors annual report (or, if there is no such report, a copy of such report for its parent company) containing audited, consolidated financial statements for such fiscal year, and (b) within *** Days after the end of each of its first
three fiscal quarters of each fiscal year, a copy of Guarantors quarterly report (or, if there is no such report, a copy of such report for its parent company) containing unaudited consolidated financial statements for such fiscal quarter. In
all cases, the statements shall be prepared in accordance with generally accepted accounting principles. To the extent such quarterly reports are not available, upon the reasonable request of Owner in response to a credit event in the marketplace,
Guarantor shall provide unaudited management financial information for such fiscal quarter.

16.2 Standby Letter of Credit.

(i) Upon the Effective Date, Contractor shall obtain and provide to Owner an irrevocable standby letter of credit in an initial amount
equal to $*** in favor of Owner in the form attached as Exhibit J-2 (as the same may be amended or replaced from time to time in accordance with this Section 16.2, the Standby Letter of Credit).
The Standby Letter of Credit shall be issued by a U.S. commercial bank or a foreign bank with a U.S. branch with total assets of at least $5 billion having a general long-term senior unsecured debt rating of A - or higher (as rated by
Standard & Poors Rating Group) or A3 or higher (as rated by Moodys Investor Services, Inc.) and shall permit 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.

(ii) Contractor shall cause such Standby Letter of Credit to be amended or replaced as of each date 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. In the event of a Force Majuere or any other delay in completion of a payment Milestone in the Schedule, including a delay which 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.

(iii) 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 fees (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,

under a Invoice covering such Equipment or constituent part of such Equipment, notwithstanding any disputed amounts withheld or offset by Owner against any payment sought by Contractor in accordance with the terms of this Agreement. The passage of
title to Owner shall not be deemed an acceptance or approval of such Equipment (or any Service), affect the allocation of risk of loss, affect any security interest in favor of Owner therein or otherwise relieve Contractor of any obligation under
this Agreement to provide and pay for transportation and storage in connection with the Equipment. Further, upon the passage of title, the Equipment, constituent parts thereof and the unused spare parts shall be specifically excluded from the
bankruptcy estate of Contractor in the event of any bankruptcy or insolvency proceeding involving Contractor. Regardless of whether title has passed to Owner, Contractor hereby grants Owner a continuing security interest in all of the Equipment to
the extent of the payments made in connection therewith, whether now owned or hereafter acquired, wherever located and all attachments and accessions thereto and all replacements thereof, all drawings, plans and general intangibles related thereto,
all warranties and contract rights related thereto and all proceeds of the foregoing (collectively, the Collateral), to secure all past, present and future indebtedness and obligations which Contractor owes Owner
under this Agreement. Contractor shall cause such security interest to constitute, at all times, a valid, enforceable, duly perfected, first priority security interest in the Collateral superior to all other claims to and interests in the
Collateral, including the claims of any lender, vendor or Subcontractor to Contractor, it being understood that Owner shall be responsible for initial perfection of such security interest. Contractor hereby authorizes Owner to file financing
statements naming Contractor as debtor with respect to the Collateral in such jurisdictions as Owner believes are necessary to perfect the foregoing security interest. Contractor shall execute and deliver at all times requested by Owner all other
instruments and documents necessary or desirable to establish, perfect or maintain this security interest. At the request of Owner, Contractor shall clearly label the Collateral with Owners name for the purpose of proper identification of the
Collateral.

accepted by, Contractor. To the extent of the proceeds of BAR insurance, Contractor shall be obligated to replace, repair or reconstruct the Equipment that is lost, damaged, or destroyed before the risk of loss of the Equipment is transferred to
Owner. For Equipment or Materials that are removed from the Site for repair, replacement or refurbishment under the Warranty, the risk of loss to such Equipment or Materials shall pass to Contractor at the time of the loading of such Equipment or
Materials on the carrier at the Owners Facility. Owner will resume the risk of loss of such Equipment or Materials upon completion of the unloading of the repaired, replaced or refurbished Equipment from the carrier at Owners Facility.

|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 at Contractors expense.

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 October, 2004) 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 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

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



82

|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.

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

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



83



---

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

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



|27. | 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 pay all taxes on Contractors purchases of goods, tools, equipment, supplies
and other consumables which are not permanently incorporated into the Project and which remain the property of Contractor. Contractor shall also pay all taxes attributable to Contractors construction equipment, temporary buildings and other
property used by Contractor in its performance of this Agreement. Allowance for such taxes is included in the Contract Price, and Contractor shall pay those taxes when assessed, without claim against Owner for reimbursement. Contractor shall impose
a similar obligation on all Subcontractors and shall ensure that no Subcontractor shall have any claim against Owner for reimbursement of those taxes.

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



84



---

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

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

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

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

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

(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.



85



---

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

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

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

27.5 Tax Indemnification.

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

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

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



86



---

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 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



87



---

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

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

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

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

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

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

Exhibit J-1



***

THIS GUARANTY is given this 11th day of July, 2007 by *** (Guarantor),for the benefit of DUKE ENERGY CAROLINAS, LLC, a limited liability company organized under the laws of the State of North Carolina
(Owner).

WITNESSETH:

WHEREAS, Owner plans to have constructed a new nominally-rated 800 MW supercritical generating Unit 6 and a new flue gas desulfurization system on the existing Unit 5 at its electric generating facility known as Cliffside Steam
Station (the Project); and

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

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

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

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

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

(b) if for any reason Contractor shall fail to perform or cause to be performed any other duty, obligation, warranty, guarantee
or responsibility imposed upon Contractor under the Contract, Guarantor will, upon receipt of written notice of such failure and demand by Owner, perform or cause to be performed such duty, obligation, warranty, guarantee or responsibility in
accordance with the Contract.

2. UNCONDITIONAL OBLIGATION. This is a guarantee of payment and performance and not of collection. The liability of
Guarantor under this Guaranty is direct, irrevocable and not conditional or contingent upon the pursuit of any remedies against Contractor or any other



2 of 6



---

Exhibit J-1



person or entity, nor upon any other recourse available to Owner, its successors, endorsees, transferees, or assigns. Guarantor waives any and all rights it
may now or in the future have under law or in equity to require either that an action be brought against Contractor or any other person or entity as a condition to proceeding against Guarantor.

3. ABSOLUTE OBLIGATION. The obligations of Guarantor under this Guaranty are absolute and without regard to lack of power or authority of Contractor to enter into
the Contract or any other circumstances which might otherwise constitute a legal or equitable discharge of a surety or guarantor. Guarantor agrees that Owner and Contractor may modify or amend the Contract and that Owner may delay or extend the date
on which any guaranteed obligation must be paid or performed, or release Contractor from any guaranteed obligation or waive any right thereunder, all without notice to or further assent by Guarantor, which shall remain bound by this Guaranty,
notwithstanding any such act by Owner. The obligations of Guarantor under this Guaranty shall not be affected, reduced, or impaired upon the happening of any of the following events:

(a) the failure to give notice to Guarantor of the occurrence of a default under the terms and provisions of the Contract, provided Owner has complied
with the notice requirements of the Contract;

(b) the change, modification or amendment of any obligation, duty, guarantee, warranty,
responsibility, covenant or agreement (including without limitation Change Orders) set forth in the Contract;

(c) any failure, omission,
delay by or inability on the part of Owner to assert or exercise any right, power or remedy conferred upon Owner under the Contract;

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

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

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

(g) the assignment of any right, title or interest of Owner in the Contract pursuant to the terms thereof to any other person or entity.

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



3 of 6



---

Exhibit J-1



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

5. WAIVER OF NOTICE. Guarantor hereby waives notice of
(a) Owners acceptance and reliance on this Guaranty; (b) default or demand in the case of default, provided such notice or demand has been given to or made upon Contractor; and (c) any indulgences, extensions or consents granted
to Contractor or any other surety. Guarantor waives promptness, diligence, presentment, demand of payment or enforcement and any other notice with respect to any of the guaranteed obligations and this Guaranty.

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

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

8. ASSIGNMENT. This Guaranty shall inure to the benefit of Owner, its successors and permitted assigns and shall be binding upon Guarantor and its successors and permitted assigns. Owner may at any time assign
this Guaranty to any person or entity to whom Owner assigns the Contract in accordance with the terms thereof, including a collateral assignment of Owners right, title and interest in and to this Guaranty in connection with obtaining financing
for the Project. Guarantor may not assign this Guaranty without the prior written consent of Owner, which may be withheld in Owners sole discretion.

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

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

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

(c) the execution and delivery by Guarantor of this Guaranty, and the performance by Guarantor of its obligations hereunder
(i) are within Guarantors corporate powers, (ii) have been duly authorized by all necessary action, (corporate or otherwise), (iii) do

not contravene any law or regulation applicable to or binding on Guarantor or any of its properties, and (iv) do not require the consent or approval of
any person or entity which has not already been obtained;

(d) this Guaranty constitutes the legal, valid and binding obligation of
Guarantor enforceable against Guarantor in accordance with its terms.

10. SEVERABILITY. The invalidity or unenforceability of any provision of this
Guaranty shall not affect the validity or enforceability of the remaining provisions of this Guaranty, which shall be enforced to the greatest extent permitted by law.

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

12. WAIVERS. No delay or omission to exercise any right or power of Owner shall impair any such right or power or shall be construed to be a waiver thereof. No
waiver of any right of Owner under this Guaranty shall be effective unless made pursuant to an instrument in writing duly executed by Owner.

13. NOTICES. All notices permitted or required to be given under this Guaranty shall be in writing and
shall be deemed duly given when sent by telefacsimile transmission, by overnight courier, by personal delivery or on the seventh (7th) day following

|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.
| | - |  | ------------------------------------------------



| |  |  | All air conditioning/heating/ventilation required to maintain the plant environment on the test day will be operating.

| |  |  | Redundant or surge capacity equipment shall be energized.
| | - |  | ---------------------------------------------------------

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

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



---

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

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

by which the Contractor demonstrates to Owner that the Unit 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 Test shall be maintained and measured at the
high side of the main step up transformer. The time weighted average net electrical output of the Unit generated during the Reliability Test period shall be utilized in determining the Test 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.

|Mercury(Hg) |  | *** |  |  |  | *** |  | The total mercury content in the coal as fired shall be determined using ASTM method D6414-01 or ASTM Method D3684 01, and the stack mercury emissions shall be measured using ASTM
D6784-02, EPA 40CFR60 part75, Appendix K (Ontario Hydro Method) or mutually agreed Certified Mercury CEMS if available. The total mercury content of the coal shall be determined from a representative, composite as fired fuel, sample that is
collected over the mercury stack emission test duration and shall be converted and expressed in terms of lb/1012Btu (HHV) of the composite fuel blend
sample tested. The mercury stack emissions shall be converted to and expressed in terms of EPA F- Factor methodology in accordance with 40CFR 60 Appendix A, methods 2,3 and 5 and based on the composite fuel blend analysis.
