 SECTION 4 
 GENERAL CONDITIONS 
 GENERAL CONDITIONS

 GC-1 ENTIRE AGREEMENT 
  

	1.1	This Agreement embodies the entire agreement between Buyer and Seller. The Parties shall not be bound by or liable for any statement, representation, promise or understanding not
set forth herein. Nothing contained in proposals, correspondence, discussions, order acknowledgements or other of Seller’s forms has any effect on this Agreement unless specifically incorporated herein. 

  

	1.2	No modifications to this Agreement shall be valid unless reduced to writing and signed by both Parties pursuant to Clause GC-2 (Changes). 

 GC-2 CHANGES 
  

	2.1	Buyer, through its authorized procurement representative, may at any time direct, in writing, changes, including but not limited to changes in any one or more of the following:
(1) drawings or specifications; (2) additions to or deletions from quantities ordered; (3) Delivery schedule; (4) method of shipment or packing; (5) place of Delivery. If any such change causes an increase or decrease in the
cost or timing required to provide the Equipment, or otherwise affects Seller’s ability to meet its obligation, an equitable adjustment shall be made in the Agreement Price or Delivery schedule and/or other relevant terms and the Agreement
shall be modified by written amendments or revisions executed by authorized representatives. Any request by the Seller for adjustment under this Clause GC-2 (Changes) must be asserted promptly by written notice to Buyer’s authorized
representative and in no case later than within twenty (20) Days from the date of receipt by Seller of the notification of a change, unless the Parties mutually agree to extend the time required to assess and determine the resulting impact.
Buyer shall respond to Seller’s request for adjustment within thirty (30) days of receipt of Seller’s notice. However, nothing in this clause shall excuse Seller from proceeding with the order as changed. Failure by Seller to timely
give the required notice hereunder will preclude Seller’s right to request any adjustment. In the event that Buyer and Seller are not able to reach agreement on a firm price for a Buyer directed change after good faith negotiations by the
Parties or in case of an emergency endangering life or property or the Facility has ceased operation or is materially and adversely affected in its operation requiring immediate corrective action, Seller will proceed with implementation of the
change on a time and materials basis, including a reasonable profit. In such event, Seller agrees to provide in a timely manner such documentation as is reasonably sufficient for Buyer to determine the accuracy of impact of jobsite changes on a time
and material basis. 

  

	2.2	If this Agreement requires Buyer to review and comment on Seller’s technical documents, Seller shall submit, within twenty five (25) Days from the date of Seller’s
receipt of such comments, any request for adjustment resulting from implementation of Buyer’s comments. No adjustment will be made hereunder unless Buyer, through its authorized procurement representative, confirms the change in writing.

  

	2.3	A Change in Law affecting Seller’s Work under this Agreement (except for changes relating to taxes to be paid by Seller) and occurring after the Effective Date shall be
considered a change and will be handled in accordance with Clause GC-2.1 above, provided that Seller gives notice to Buyer of such Change in Law no later than ten (10)

 days after
(i) Seller becomes aware of such Change in Law or (ii) the earlier time at which it would be commercially reasonable to expect that Seller should have become aware of such Change in Law, together with details as to the impact of such
Change in Law on performance of the Work. 
  

	2.4	Suspension instructed by Buyer pursuant to Clause GC-7 (Suspension) will also be treated as a change and will be handled in accordance with Clause GC-2.1 above, unless such
suspension arises as a result of any fault, defect or other failure to perform which is attributable to Seller. 

 GC-3 DELIVERY

 Performance and Delivery of the Seller’s obligations shall be in accordance with the Guaranteed Milestone Dates. However, to the
extent the Buyer’s failure to fulfill any of its material obligations under this Agreement, (except payment obligations), actually and demonstrably delays Seller in the performance of its critical path activities, Seller shall be entitled to an
equitable adjustment to the affected Guaranteed Milestone Date(s), except to the extent that Seller fails to exercise good faith efforts to mitigate the impact of such Buyer delay and provided in any event that Seller must give notice to Buyer
within ten (10) days after (i) Seller becomes aware of the occurrence of such Buyer delay or (ii) the earlier time at which it would be commercially reasonable to expect that Seller should have become aware of such occurrence. Such
notice will specify the nature of the occurrence and the reason(s) why Seller believes additional time should be granted and the length of the delay occasioned by reason of such Buyer delay. Strict compliance with this Clause GC-3 (Delivery) is a
condition precedent to any entitlement to an extension of the affected Guaranteed Milestone Date(s). Failure by Seller to timely give the required notice hereunder will preclude Seller’s right to invoke the protection of this Clause GC-3
(Delivery) to the extent the Buyer is prejudiced by such failure. Seller shall use its reasonable best efforts to minimize or avoid the delay caused by the Buyer delay and the initial notice provided by Seller shall describe in detail the efforts of
Seller that have been or are going to be made in this regard. Upon mutual agreement of the Parties to Seller’s entitlement for an equitable adjustment to the affected Guaranteed Milestone Date(s), this Agreement shall be modified by written
amendment or revision executed by the Parties’ authorized representatives. 
 GC-4 TITLE AND RISK OF LOSS 
  

	4.1	Title to Equipment or materials to be shipped from within the United States shall pass to Buyer when available for shipment from the manufacturer’s factory. Title to Equipment
or materials to be shipped from a country other than the United States shall pass to Buyer at the port of export immediately after the Equipment or materials have been cleared for export. Title to services provided by Seller shall pass as such
services are performed and accepted by Buyer. In order to protect Buyer or Owner’s interest in Equipment with respect to which title has passed to Buyer or Owner but which remains in the possession of Seller, Seller shall take or cause to be
taken all steps necessary under the applicable laws and regulations to maintain Buyer’s or Owner’s title and to protect Buyer or Owner against claims by other parties with respect thereto. 

  

	4.2	Shipment to Storage. If the Equipment cannot be shipped to Buyer, as specified in this Agreement, due to any cause attributable to Buyer, Seller may ship such Equipment to storage.
If such Equipment is placed in storage, including storage at the facility where

 manufactured, the
following conditions shall apply: (a) title shall thereupon pass to Buyer if it had not already passed; (b) any amounts otherwise payable to Seller upon delivery or shipment shall be payable upon presentation of Seller’s appropriately
supported invoices and certification of cause for storage; (c) all expenses incurred by Seller, such as for preparation for and placement into storage, handling, inspection, preservation, insurance, storage, removal charges and any taxes shall
be payable by Buyer upon submission of Seller’s appropriately supported invoices; and (d) Upon Buyer’s notification, Seller shall resume delivery of the Equipment to the originally agreed point of delivery. Seller shall submit
invoices under this Clause GC-4.2 on a monthly basis, and Buyer shall pay those invoices within thirty (30) Days of receipt. 
  

	4.3	Notwithstanding the foregoing, Seller shall be responsible for and shall bear any and all risk of loss or damage to the Equipment until Delivery in accordance with the delivery
provisions of this Agreement. Upon such delivery, risk of loss or damage shall pass from Seller: provided however, that any loss or damage, whenever occurring, which results from Seller’s non-conforming packaging or crating or from any defect
in the Equipment shall be borne by Seller. 

 Notwithstanding the foregoing, Seller warrants that upon passage of title to the
Equipment in accordance with this Clause GC-4 (Title and Risk of Loss), Buyer or Owner will have good and indefeasible title to such Equipment, and such Equipment will not be subject to any lien, privilege, security interest or other defect in
title. IN THE EVENT OF ANY NONCONFORMITY WITH THE FOREGOING WARRANTY, SELLER, AT ITS OWN EXPENSE, UPON WRITTEN NOTICE OF SUCH FAILURE, SHALL INDEMNIFY OWNER AND BUYER FROM THE CONSEQUENCES OF AND DEFEND THE TITLE TO SUCH EQUIPMENT AND IF NECESSARY,
SHALL PROMPTLY REPLACE SUCH EQUIPMENT AND ANY OTHER AFFECTED PORTION OF THE WORK, AND SUCH OBLIGATION SHALL SURVIVE THE EXPIRATION, CANCELLATION OR TERMINATION OF THIS AGREEMENT, INCLUDING THE WARRANTY PERIOD. 
 GC-5 INFRINGEMENT 
  

	5.1	SELLER SHALL, AT ITS OWN EXPENSE, FULLY HOLD HARMLESS, INDEMNIFY AND DEFEND INDEMNIFIED PARTIES UNDER THIS AGREEMENT AGAINST ANY CLAIM, SUIT, ACTION, PROCEEDING OR INVESTIGATION
WHICH IS BASED UPON A CLAIM, WHETHER RIGHTFUL OR OTHERWISE, THAT ANY EQUIPMENT, OR ANY PART THEREOF, OR AN OTHER ITEMS OR SERVICES FURNISHED BY SELLER UNDER THIS AGREEMENT CONSTITUTES AN INFRINGEMENT OF ANY DOMESTIC OR FOREIGN PATENT, COPYRIGHTS OR
OTHER INTELLECTUAL PROPERTY, TRADEMARK, PROPRIETARY OR CONFIDENTIAL RIGHTS, OR UNAUTHORIZED DISCLOSURE OR USE OF ANY TRADE SECRET AND SELLER SHALL PAY ALL RESULTING DAMAGES INCLUDING LEGAL EXPENSES AS PROVIDED IN CLAUSE SC-5.3 BELOW. IF, IN ANY SUCH
CLAIM, SUIT, ACTION, PROCEEDING OR INVESTIGATION, A TEMPORARY RESTRAINING ORDER OR PRELIMINARY INJUNCTION IS GRANTED, SELLER SHALL MAKE EVERY REASONABLE EFFORT, BY GIVING A SATISFACTORY BOND OR OTHERWISE TO SECURE THE SUSPENSION OF THE INJUNCTION OR
RESTRAINING ORDER. In case said Equipment, or any part thereof, are in such suit or action held to constitute infringement and/or use is permanently enjoined, the Seller shall, at its own expense, subject to the following provisions, either procure
for the Buyer and Owner an irrevocable, royalty-free license to continue using such Equipment, or with Buyer’s prior written approval which

 GENERAL CONDITIONS 
 shall not be
unreasonably withheld, replace same with substantially equal but noninfringing Equipment or modify them so they become noninfringing, provided that no such replacement or modification shall in any way amend or relieve Seller of its Equipment
Performance Guarantees, warranties, guarantees or other obligations set forth in this Agreement. Further, Seller agrees that it shall not settle any suit for which it is providing indemnity under this Clause GC-5 (Infringement) without the prior
consent of the Indemnified Parties, such consent not to be unreasonably withheld so long as such settlement completely discharges or releases the indemnifiable claims against the Indemnified Parties and does not impose by way of consent decree,
injunction or otherwise any restraint or limitations on such parties; operations or upon the operation or other use of the Facility. Buyer acknowledges it may be required to enter into certain license agreements, which shall be provided by Seller at
no additional cost to Buyer or Owner, with regard to the use of Seller proprietary computer software. 
  

	5.2	The preceding paragraph shall not apply to any Equipment, or any part thereof, manufactured to Buyer’s or Owner’s detailed design or modifications to any Equipment or part
thereof made by Buyer or Owner. As to such Equipment or part, the Seller assumes no liability whatsoever for infringement. 

  

	5.3	Seller’s obligation to hold Indemnified Parties harmless under this Clause GC-5 (Infringement) includes responsibility for paying reasonable legal expenses and other direct
costs incurred by Indemnified Parties in connection with the defense and settlement of any claim or suit within the scope of this clause. In connection with this indemnity: (a) Indemnified Parties shall promptly notify Seller of any claim or
suit or proceeding involving Indemnified Parties in which such infringement is alleged, and Indemnified Parties shall permit Seller to control completely the defense or compromise of any such allegation of infringement in which case Seller may
select counsel after consultation with Indemnified Parties, provided that (i) Buyer is consulted and kept reasonably informed of the claims, litigation, and negotiations, (ii) Indemnified Parties shall be entitled at Indemnified
Parties’ expense to participate in such defense, and (iii) no compromise shall be adverse to Indemnified Parties without such party’s consent and (b) Buyer shall render such reasonable assistance at Seller’s cost in the
defense thereof as Seller may require. If the defendants in any such action include both Seller and an Indemnified Party and the Indemnified Party shall have reasonably concluded that there may be legal defenses available to it which are in conflict
with those available to the Seller, and that such conflict materially prejudices the ability of the counsel selected by the Seller to represent both Parties, such Indemnified Party shall have the right to select separate counsel reasonably
acceptable to the Seller to participate in the defense of such action on its own behalf at Seller’s expense. 

  

	5.4	If any claim, suit, action, proceeding or investigation arises as to which the indemnity provided for under this Clause GC-5 (Infringement) hereof may apply and Seller, after being
given written notice by the Indemnified Party promptly upon becoming aware of such claim, suit, action, proceeding or investigation, fails to assume the defense of, or to diligently defend, such claim, action, proceeding or investigation, then the
Indemnified Party may, upon giving prior notice thereof to Seller, at the expense of Seller, contest (or, with the prior written consent of Seller, settle) such claim. 

  

	5.5	Notwithstanding any proprietary legends or copyright notices to the contrary, Indemnified Parties may copy or reproduce documents and information furnished by Seller in connection
with Seller’s proposal and with this Agreement and distribute such copies or

	 	F.	The Prime Contract will include an initial cure period beginning on the Substantial Completion Date and ending one hundred eighty (180) days later (“Cure Period”) for
the achievement of the Facility Performance Guarantees. During the Cure Period, Seller shall exercise all reasonable efforts to make all refinements, repairs, and modifications that may be necessary or desirable to enhance Equipment performance up
to compliance with a 100% level of achievement of all Equipment Performance Guarantees. In the event that the Facility Performance Guarantees have not been achieved on or prior to the expiry of the Cure Period, subject to consultation with Seller,
Buyer may either (a) submit to Owner a remedial plan for achievement of the Facility Performance Guarantees, or (b) decline to submit such a remedial plan. 

  

	 	(i)	In the event that Buyer declines to submit a remedial plan then Performance LDs shall be payable by Seller under Section 5, Appendix 4 based on the results of the Completed
Performance Test as determined by Buyer and Owner; provided, however, if the performance shortfall is due to Seller, Buyer shall submit a remedial plan as requested by Seller. 

  

	 	(ii)	In the event that Buyer submits a remedial plan (including proposal for extension to the Cure Period (“Cure Period Extension”) but Owner does not approve such remedial
plan, then Performance LDs shall be payable by Seller under Section 5, Appendix 4 based on the results of the Completed Performance Test; but, notwithstanding payment of such Performance LDs, Seller shall, if required by Buyer, continue to
exercise all reasonable efforts during the Cure Period Extension to make all refinements, repairs, and modifications that may be necessary or desirable to enhance Equipment performance up to compliance with a 100% level of achievement of all
Equipment Performance Guarantees and shall, if required by Buyer, support the conduct of further Performance Guarantee Tests during the Cure Period Extension, provided that Seller’s reasonable additional costs incurred in connection with such
support will be borne by Buyer so long as all Equipment Performance Guarantees have been met as at the expiry of the initial Cure Period and so long as all Equipment Performance Guarantees continue to be met during the Cure Period Extension.

  

	 	(iii)	In the event that there is a Cure Period Extension then Seller’s liability for Performance LDs with respect to each Equipment Performance Guarantee shall be reassessed based on
the results of the Completed Performance Test conducted during the Cure Period Extension,, and 

  

	 	(x)	to the extent that the Performance LDs as reassessed are less than the amount of Performance LDs previously paid by Seller pursuant to paragraph (ii) above, then the amount of
the difference shall be refunded to Seller; and 

  

	 	(y)	to the extent that the Performance LDs as reassessed exceed the amount of Performance LDs previously paid by Seller pursuant to paragraph (ii) above, then the amount of the
difference shall be paid by Seller, in addition to the Performance LDs previously paid by Seller.

performance up to compliance with a 100% level of achievement of all Equipment Performance Guarantees and shall, if required by Buyer, support the conduct of further Performance Guarantee Tests during the Cure Period Extension, provided that
Seller’s reasonable additional costs incurred in connection with such support will be borne by Buyer so long as all Equipment Performance Guarantees have been met as at the expiry of the initial Cure Period and so long as all Equipment
Performance Guarantees continue to be met during the Cure Period Extension. 
  

	 	G.	Buyer will, to the extent available, allow Seller access to Seller’s Equipment for tuning; however Buyer does not guarantee any specific allocation of time.

  

	 	H.	Except as provided in Section F above, upon payment of Performance Liquidated Damages under this Appendix 4, no further repairs and modifications are required to improve performance
with regard to the Equipment Performance Guarantees for which the liquidated damages are paid. This provision shall not be construed to limit Seller’s warranty obligations pursuant to Special Conditions Clause SC-6, entitled
“Warranties.” In the event that the Facility has achieved Substantial Completion but Seller has not achieved all of the Equipment Performance Guarantees, Seller shall be obliged at request of Buyer, to modify, repair, adjust and re-test
the Equipment in order to demonstrate achievement of the Equipment Performance Guarantees. In the event that by the earlier of expiry of the Cure Period (as may be extended) and the Guaranteed Final Completion Date Seller has failed to achieve any
or all of the Equipment Performance Guarantees Seller shall be liable to pay Performance Liquidated Damages to Buyer as determined and directed by Buyer in respect of those Equipment Performance Guarantees which Seller has failed to achieve.

	 	J.	Further understandings in respect of the Reliability LDs provided in Article 4.0 are set out in paragraphs (a) through (e) below: 

  

	 	a.	Buyer (acting reasonably, fairly and equitably) shall determine responsibility for shortfalls in the guaranteed Facility EAF as between Buyer, Seller and Buyer’s other
contractors or suppliers based upon the calculated EEAF of the Seller’s Equipment. If and to the extent that such shortfalls are in Buyer’s opinion (acting reasonably, fairly and equitably) the responsibility of Seller, Buyer (acting
reasonably, fairly and equitably) shall assess and apportion responsibility to the Seller. 

  

	 	b.	Buyer shall give written notice to Seller of any determination of responsibility under this clause, and of any resulting assessment and obligation to pay liquidated damages to Buyer
on a weekly basis. Buyer will promptly provide Seller with full details of all relevant calculations and with copies of all relevant correspondence and other documents upon which such determination, assessment and attribution were based.

	 	c.	With respect to Reliability LDs, if Owner does not recover or seek to recover from Buyer liquidated damages for failure to achieve the guaranteed Facility EAF under the Prime
Contract, Buyer shall not be entitled to recover Reliability LDs under this Agreement for Seller’s failure to meet his guaranteed EEAF. 

  

	 	d.	In no event shall the Reliability LDs recoverable from Seller be in excess of the amount of Reliability LDs recovered or sought from Buyer by Owner for failure to achieve the
Buyer’s guaranteed Facility EAF under the Prime Contract. 

  

	 	e.	Buyer has the sole right to determine and declare which tests or series of tests will be used to demonstrate the overall Facility performance, provided however, with respect to the
720 hour Reliability Test, in the event that the Guaranteed EAF is not met, Buyer shall select the period in which the Facility achieved the highest EAF. 

  

	 	K.	Performance Tests shall be run in accordance with this Appendix 4. Buyer shall give Seller reasonable notice of the date or dates on which the Performance Tests shall begin.

  

	 	L.	The Parties agree that it would be extremely difficult and impracticable under the presently known and anticipated facts and circumstances to ascertain and affix the actual damages
that Buyer would incur should the Facility meet the Minimum Facility Performance Criteria but fail, due to reasons attributable to Seller’s Equipment, to meet the Facility Performance Guarantees and/or Reliability Guarantee. Accordingly, the
Parties agree that the amounts specified herein for Performance Liquidated Damages and Reliability Liquidated Damages are not intended as penalties but rather as reasonable projections of damages that Buyer might incur for failure to meet the
Facility Performance Guarantees and Reliability Guarantee, respectively. 

  

	 	M.	Provided the Facility has achieved Final Completion and the Equipment has met the Minimum Performance Criteria, Seller’s maximum aggregate cumulative liability for Performance
Liquidated Damages and Reliability Liquidated Damages shall be as set forth in Special Conditions Clause SC-30.3, entitled “Limitation of Liability”. 

  

	3.0	EQUIPMENT PERFORMANCE GUARANTEES, PERFORMANCE GUARANTEE TESTS AND PERFORMANCE LIQUIDATED DAMAGES 

  

	 	A.	Equipment Performance Guarantees: Seller guarantees that in the Completed Performance Tests declared by Buyer to demonstrate the requirements of the Facility to achieve Final
Completion under the Prime Contract, Seller’s Equipment will achieve the Equipment Performance Guarantees associated with such Completed Performance Tests as indicated in Table 3.0 A. .

	 	C.	Performance Liquidated Damages: 

 If in the
Completed Performance Test, Seller’s Equipment Performance Guarantees are not met due to a failure of Seller’s Equipment to meet the Equipment Performance Guarantees as defined in Section 2, Appendix “F”, “Steam Turbine
Generator Thermal Performance Requirements”, Guarantee Case, for reasons attributable to Seller, Seller shall pay as Performance liquidated damages, and not as a penalty, an amount calculated at the rate shown below for any deficiencies in
meeting the Equipment Performance Guarantees.

 Notwithstanding the above, Seller’s Noise Guarantee shall be a “Make Right”
guarantee. 
 Seller’s right to liquidate any shortfall in the Equipment Performance Guarantees is contingent upon the Seller achieving
the Minimum Performance Criteria. If Seller’s Equipment fails to achieve the Minimum Performance Criteria then the Seller has a Make Right obligation with respect to the Minimum Performance Criteria. 
 The Equipment must meet each Equipment Performance Guarantee, unless specifically stated otherwise. Excess performance in one Equipment Performance
Guarantee shall not be allowed to offset shortfalls in performance of another Equipment Performance Guarantee. 
 With respect to those
Equipment Performance Guarantees for which Performance Liquidated Damages are provided, the payment by Seller to Buyer of such Performance Liquidated Damages in accordance with this Appendix 4 shall be Buyer’s sole and exclusive remedy in full
and final satisfaction of Seller’s liability for performance shortfall., subject to the provisions of Clause 6.0, Paragraph C of this Appendix 4 imposing on Seller costs of any retesting to the extent Performance Tests fail for reasons
attributable to Seller.

RELIABILITY GUARANTEE, RELIABILITY TEST AND RELIABILITY LIQUIDATED DAMAGES 
  

	 	A.	Reliability Guarantee: Seller guarantees that the EEAF, as measured during the Completed Reliability Test (and calculated in accordance with paragraph (D) below), will
not be less than ***% 

  

	 	B.	Reliability Test: The Reliability Test consists of a 720-hour period of operation of the Facility, will be conducted in accordance with the procedures and protocols described
in Clause 7.0 below, and is a requirement for achieving Final Completion. 

 Seller shall participate with Buyer in a
Reliability Test to demonstrate to Owner that the Facility can achieve an Equivalent Availability Factor of 92% or better during the 720 hour Reliability Test period. 
 The period of testing for the Reliability Test shall commence whenever the Facility is ready after the startup of the Facility and continue until the Facility has achieved the guaranteed Equivalent Availability Factor
or better over a period of 720 hours, but not beyond the Guaranteed Final Completion Date. Subject to Clause 2.0 J.e, above, Buyer may at any time look back over the test data and designate the time period to be declared as the Reliability Test.
Full outage due to Force Majeure events or interruptions because the power purchaser cannot or will not accept power, and the related time required to shut down and restart for these outages, will not be counted as test hours and will extend the 720
hour test period. 
  

	 	a.	The Equipment Equivalent Availability Factor (EEAF) and the Facility Equivalent Availability Factor (EAF) shall be logged from the date of commencement of the Reliability Test.

  

	 	b.	Buyer will make all reasonable efforts to allow Seller access to the Equipment in order to minimize repair time. 

  

	 	c.	Buyer will advise Seller when any event occurs which affects the EEAF. 

  

	 	d.	Seller may have personnel present to monitor operation until the guarantee period has been completed.

	 	D.	To determine the EAF, an availability factor (AF) will be calculated for each dispatch level requested by the Owner during the designated test period. The sum of the individual AFs,
as calculated at each dispatch level, will be averaged on a time-weighted basis to determine the equivalent availability over the total test period. EAF is defined as follows: 

 EAF = {[(AF1 x DP1) + (AF2 x DP2) + . +
(AFn x DPn)] ÷ TP} x 100% 
 Where: 
  

					
	AF	  	=	  	Availability factor calculated at each individual dispatch level and dispatch period as follows:
			
	AF	  	=	  	(NKWHO) ( (DL x DP)
			
		  		  	If the dispatch level for any dispatch period is zero, then the corresponding AF for that dispatch period is 1, provided the Facility is available.
			
	NKWHO	  	=	  	Net energy output calculated as the sum of kilowatt-hours generated by the Facility over each dispatch period, as measured at the high voltage side of the main transformer using the
Facility’s metering devices and as adjusted for the Facility guaranteed conditions.
			
	DL	  	=	  	The net electrical dispatch level, in kilowatts, assigned by the dispatch authority. The dispatch level shall not be greater than the guaranteed Net Electrical Output of the Facility. The
dispatch level shall be constant over the dispatch period to which it applies. During periods of ramping the Facility load up or down to meet a dispatched load, the dispatch level will be considered the lower of the two dispatch loads assigned by
the dispatch authority. The DL cannot exceed the lesser of (1) the NEO or (2) the Net Electrical Capacity test results selected by Buyer to demonstrate the Net Electrical Output guarantee to Owner.
			
	DP	  	=	  	The period associated with each individual dispatch level, measured in hours. The sum of the dispatch periods shall equal the total test period duration.

 The EEAF will be determined as noted below. 
  

			
	EEAF	  	= [AH-(EUDH+EPDH)]/PH * 100%

 And: 
  

					
	AH	  	=	  	PH – (FOH + MOH + POH)
			
	EUDH	  	=	  	Unplanned Derated Hours x Size of Reduction / MDC
			
	EPDH	  	=	  	Planned Derated Hours x Size of Reduction / MDC

 Where: 
  

					
	AH	  	=	  	Available Hours
			
	PH	  	=	  	Period Hours = 720 Hours declared by Buyer to demonstrate the EAF
			
	FOH	  	=	  	Forced Outage Hours attributable to Seller’s Equipment
			
	MOH	  		  	= Maintenance Outage Hours attributable to Seller’s Equipment
			
	POH	  	=	  	Planed Outage Hours attributable to Seller’s Equipment
			
	EUDH	  	=	  	Equivalent Unplanned Derated Hours attributable to Seller’s Equipment
			
	EPDH	  	=	  	Equivalent Planned Derated Hours attributable to Seller’s Equipment
			
	MDC	  	=	  	Maximum Dependable Capacity = DL (as defined in the EAF equation)

 In determining the EUDH and EPDH, the size of the reduction shall be determined based upon the
shortfall in kilowatt-hours in the net electrical output from the MDC during the period of derated operation attributable to Seller’s Equipment. 
 Buyer shall “look back” over the data collected since the declared start of the Reliability Run and declare a 720 period to use as the basis of demonstrating the EAF and the Seller’s EEAF. 

When the Facility is required for dispatch and a fault occurs resulting in a total loss of generation, the period of the forced outage shall begin when
the Facility has been taken out of service such that it is no longer capable of being dispatched as evidenced by the operation records and shall end when the Facility has been, or was made ready to have

 A Planned Outage shall begin when the Facility has been taken out of service such that it is no longer capable of being dispatched by Owners as evidenced
by the operation records and shall end when the Facility has been returned to the required operating condition (in accordance with the start-up and ramp-up rates included in the station manuals). 
 Buyer shall have the right at all reasonable times during the Reliability Test to inspect the Facility and all ancillary parts thereof. If as a result of
such an inspection, Buyer becomes aware of abnormal operating conditions or an impending failure, and if Owners and Buyer agree (each acting reasonably), the Facility shall be shut down in order to permit the parties to undertake a detailed
inspection over such period as the parties shall agree to be reasonable in the circumstances. 
 5.0 FUNCTIONAL TESTS 
 Final Completion of the Facility requires successful completion of Functional Tests as further detailed herein:

 Net Electrical Output
(NEO) 
 The Net Electrical Output of the Facility shall be determined as the average of the corrected Net Electrical Output measured
during two 4-hour periods, after correcting to the Guarantee Conditions of the Facility. 
 Net Heat Rate Calculation 
 Net Heat Rate (NHR) is not directly measurable and will be determined analytically based on the average of tests using the NHR calculations described
below: 
  

					
	NHR	  	=	  	            THR            
		  		  	 (NEO/GEO) (BEF)

 Where 
  

					
	THR	  	=	  	Turbine Heat Rate, Btu/kWHr, defined as follows and determined by the average of two tests in accordance with the “Alternative Test” described in paragraph 1.3.3 of ASME PTC 6-2004
“Performance Test Code 6 on Steam Turbines”, with a test period of four (4) hours each, will be conducted to determine the turbine cycle heat rate. Test results will be corrected in accordance with ASME PTC 6 – 2004 “Alternative
Test” and Seller’s performance correction curves for deviations from the Guarantee Conditions. All other group 1 and 2 corrections to the as-tested turbine cycle heat rate will not be permitted. The corrected test specific heat rates shall
agree within 0.5 percent. Measured/calculated data will be used as inputs in the following formula:

  

	
	 THR= [M1 (H1 - HF) + M2 (HHR - HCR)]*(TAC)

	 	C.	Each Performance Test shall be performed at a time selected by, and at the discretion of Buyer. Seller shall provide all test personnel and test equipment as required per
Section 5, Appendix 4, Attachment 5 to test Seller’s Equipment for the Equipment Performance Guarantees associated with a Performance Test. If, due to failure of Seller’s Equipment, an additional Performance Test is required, Seller
shall be responsible for the cost of this retest (excluding fuel and operator costs) based on the scope of testing work allocated to Seller in Section 5, Appendix 4, Attachment 5. With respect to any Performance Test, Buyer may declare a
“Completed Performance Test”, which shall establish the time of completion for such test if accepted by Owner. 

 Buyer shall give reasonable notice to Seller prior to the dates on which any Performance Test will be made, it being understood that Seller may require preliminary tests and final adjustments. 
  

	 	D.	The performance of the Equipment demonstrated in each Completed Performance Test will be determined and calculated in accordance with test procedures consistent with Section 5,
Appendix 4, Attachment 5, and as mutually established by Seller, Buyer and Owner, which shall include correction factors and adjustment curves. 

  

	 	E.	All test results obtained from the Performance Tests shall be corrected to the Guarantee Conditions in accordance with the Test Procedures for the Facility.

  

	 	F.	All Performance Guarantee Tests shall be accomplished with the Facility operating wholly within its design ratings. 

 7.0 TEST PROTOCOLS AND PROCEDURES 
  

	 	A.	Guarantee Conditions 

 All Facility Performance Test
results will be adjusted analytically for deviations from the Guarantee Conditions as set forth in the Facility Test Procedures. Performance degradation of the steam turbine generator will be considered, as agreed between Buyer and Owner.

 Facility and Equipment Performance Tests will be conducted as soon as practical after the initial turbine operation. To account for turbine
aging, an adjustment to Turbine Cycle Net Heat Rate and Turbine Gross Power Output will begin to accrue from zero (0) value beginning on the date of initial synchronization. The adjustment methodology will be based on the following method:

  

			
	 By Seller:
                    
	  	By Buyer:                     

 Section 5, Appendix 4 – Performance Guarantees and Liquidated Damages 
 Page 17 of 20 

 TXU STANDARD PROJECT 
 PROJECTS      
 SECTION 5, APPENDIX 4 
 PERFORMANCE GUARANTEES AND LIQUIDATED DAMAGES 
  

	 	•	 	Comparing the results of an enthalpy drop efficiency test run on the turbine sections in the superheated region with the startup enthalpy drop test results (enthalpy drop tests
performed by the Seller). For the purposes of this adjustment methodology, the LP degradation will be assumed to equal half the IP Turbine percent degradation. 

 In the event that an initial enthalpy drop test cannot be performed, the following will apply: 
  

	 	•	 	Reviewing the operating and chemistry test logs, inspecting flow measurement elements in the cycle for deposits, and employing other methods for ascertaining the condition of the
unit as described in ASME PTC 6 Report – 1985, Section 3.07 (Refer to Figure 3.3) 

  

	 	B.	Test Interruptions 

 With the exception of the
Reliability Test, any test interruption attributable to Buyer experienced during a Facility Performance Test or Equipment Performance Test will require the re-testing of the applicable Facility or Equipment Performance Guarantees. Test data gathered
from the Facility or Equipment Performance Test prior to the interruption shall be discarded. If a test interruption occurs for reasons beyond the control of Buyer, it shall be mutually agreed to either: (a) resume the Facility or Equipment
Performance Test after the cause of the test interruption has been rectified, or (b) restart the Facility or Equipment Performance Test. 
 Upon the occurrence of a Facility or Equipment Performance Test interruption, Buyer shall notify Owner in accordance with the performance test procedure. Upon notification of an interruption, Buyer and/or Seller, with Owner’s
assistance will identify the cause, define the procedure for continuing or stopping the Performance Test or Equipment Performance Test, and identify the responsibility for any costs incurred for re-testing. 
 “Reliability Test Interruption” means any period of time the Facility is out or derated because of Force Majeure, unavailability of fuel, Owner
scheduled outages (other than at Buyer’s request), faults of the electrical grid, and failure of Owner to operate the Facility in accordance with the station operating manuals. Reliability Test Interruptions will be excluded from the
Performance Test period for test data analysis and the Performance Test shall continue when the interruption is corrected. Reliability Test Interruptions will extend the test period by an amount of time equal to the interruption. Reliability Test
data collected before the interruption may be included in the analysis. 
 Periods of exceedance of emissions limits defined in the Air Permit
shall be treated as a Reliability Test Interruption pursuant to the previous paragraph (for the duration of the exceedance period), except for periods during which the emissions exceedance resulted in a Facility derating or shutdown. 
 Upon a Facility trip caused by the Work, Owner will not be required to return the Facility to service unless the root cause of the trip has been
identified and the problem has been corrected.

 Page 18 of 20 

 TXU STANDARD PROJECT 
 PROJECTS      
 SECTION 5, APPENDIX 4 
 PERFORMANCE GUARANTEES AND LIQUIDATED DAMAGES 
 Any time period during a test for which a test interruption occurs that is beyond the control of Buyer and Seller will be excluded from the test period for test data analysis. Any interruption that is the consequence of failure of equipment
to meet operating requirements shall not be a test interruption and shall not be excluded from the test period for test data analysis. Types of interruptions excluded from the test period shall included interruptions caused by Force Majeure, test
instrumentation malfunction, unavailability of design fuel or other materials, problems in disposing of discharge materials, and operating and dispatching decisions and other causes outside Buyer’s and Seller’s control except as otherwise
provided with respect to dispatching decisions during the Reliability Test. The Reliability Test periods may, at Buyer’s option, be continuous except for permitted test interruptions per above. 
 Operator action/inaction, inconsistent with Prudent Utility Practices, or not in accordance with (or inconsistent with) the performance test procedures,
causing a failure to meet the Guaranteed Emissions levels will not constitute an emissions violation or test interruption, unless such action or inaction is at the direction of Buyer and Seller. Emissions data from an exceedance period attributable
to operator action/inaction will be excluded from analysis. All other data collected during such an exceedance period, at Buyer’s and Seller’s joint option, will be included in the analysis. 
 The failure of nonessential automatic controls and instrumentation will not preclude initiation of the Reliability Test, or require a Reliability Test
interruption if Buyer determines that the failure or unavailability of such instrumentation would not require a Facility shutdown during normal operation. 
  

	 	C.	Test Procedures 

 Seller shall submit, the later of
75 days after receipt of plant P&IDs or 365 Days before the Guaranteed Substantial Completion Date, procedures for the tests which shall include name of item to be tested, location of measurement points, manufacturer and model number of major
instruments to be utilized, any applicable correction curve(s) for off-design conditions, and a verifiable method of calculation (sample calculation) of the test results. 
 The performance of Seller’s Equipment will be based on acceptance tests in accordance with Section 5, Appendix 4, Attachment 5. 
 The Performance Tests of the Facility shall be performed using a combination of permanent Facility instrumentation and special test instrumentation for measurements. 
 Seller shall be required to support the overall Performance Test program. Seller-supplied Equipment will be required to be operated in the normal
configuration and be monitored as the Performance Tests are completed. 
 Seller shall report the results of the each Equipment Performance
Test (unless aborted) to Buyer. Buyer will report the results of each Performance Test (reflecting overall Facility performance) to Owner.

instruments with calibration used for the tests, test data, results, calculations and application of corrections to performance and design conditions.

  

	 	7.	If additional services not identified above are requested of the Seller, the Seller shall provide such services, including technical representatives of Seller’s sub-suppliers
if required by Seller, at the rates to be calculated as included in Section 1 of the Purchase Order. 

  

	 	B.	Instrumentation – General Requirements 

  

	 	1.	Instruments shall be classified as Primary and Secondary instrumentation. A Primary Instrument is defined as any instrument used to collect data required to calculate the corrected
test results (e.g. the measured parameters must enter into the calculation algorithm for turbine heat rate or turbine net power output). All other instruments are Secondary Instruments. 

  

	 	2.	Primary Instruments are further categorized as “Class 1” and “Class 2” instrumentation. Class 1 Primary Instruments are those instruments that are used to
collect data that are used to calculate the test results, and have a sensitivity of 0.2% change in corrected test results / % change in primary variable or greater. Any other primary instrument is a Class 2 Primary Instrument. Key Primary
Instrumentation details are included in Table 1. 

  

	 	3.	Secondary Instruments shall be identified in the test procedure. Secondary Instruments are variables that are measured or determined but do not enter into the calculation of
performance. Existing station instrumentation and data collection system are utilized to gather information from Secondary Instruments. No laboratory calibration is required, and Buyer is under no obligation to ensure the data quality or
availability of any Secondary Instrumentation. 

  

	 	C.	Instrumentation – Key Measurements 

  

	 	1.	Feedwater Flow 

 Feedwater flow shall be measured with the
use of an ASME throat tap flow nozzle manufactured in accordance with ASME standards including an upstream flow conditioning device (flow straightener). At least two tap sets of the Feedwater flow nozzle shall be calibrated at Reynolds numbers as
high as reasonably possible at a minimum of 20 calibration points. The discharge coefficient will be calculated from the calibration data. Extrapolation of the discharge coefficient, if necessary, shall be done using the methodology outlined in PTC
6 (2004) and PTC 6A (2000). Adequate pipe straight lengths of ASME-MFC-3M-1989 will also be ensured. The flow rate shall be determined from the methodology detailed in ASME-MFC-3M-1989 as the average flow calculated from the calibrated taps and
the corresponding calibration data. Feedwater Flow nozzle should meet the criteria of ASME PTC 6. 
 The feedwater flow meter will be
installed after the initial flushing of the system. Prior to installation, it will be visually inspected for damage. Buyer shall notify Seller in advance of this inspection date. Prior to the Equipment Performance Test, a bore scope inspection
shall, upon request of the Seller, be performed on the flowmeter from an upstream port to ensure that there are no visible changes of the flowmeter. The inspection of the flowmeter shall be conducted during a planned shutdown of sufficient

length of time to allow such inspection. However, the time period between the post-test inspection and testing should not exceed two weeks. 
 For the condition with two tap sets being calibrated, the flow rate for each tap set shall be determined from the methodology detailed in ASME-MFC-3M-1989
using the discharge coefficient obtained from the aforementioned methodology. The flow shall then be determined for each of the two tap sets. The calculated flow from each element will be obtained by averaging the two flow values 
 Buyer and Seller agree that the flowmeter described above shall be sufficient for use in the turbine heat rate and electrical output testing efforts. In
the event that the Buyer has not adequately incorporated the provisions specified under this Section C.1 for the feedwater flow meters, then the test tolerance shall be increased pursuant to Section H of this Attachment 5 to Section 5. To
determine the test uncertainty difference associated with the flowmeters, ASME PTC 6-Report 1985 shall be used as a guide.

 Any instrument not listed above that is subsequently determined to be necessary for the testing
efforts shall be detailed in the Seller’s test procedure. 
 “Accuracy Class” means the base accuracy of an instrument, as
defined by the instrument manufacturer’s published documents, prior to considering potential errors caused by drift, hysteresis, improper installation, improper ranging, etc. 
  

	 	D.	Instrumentation – Calibration and Inspection 

  

	 	1.	All primary instruments will be calibrated as detailed in Table 1, unless exception to this requirement is specifically taken herein. 

  

	 	2.	All secondary instruments need not be calibrated at all. 

  

	 	3.	When calibration of a test instrument is required, the test instruments will be calibrated or re-calibrated prior to testing in accordance with standard industry practice. In
general, all test instrumentation requiring calibration will be calibrated (or re-calibrated) within 90 days of the test. As exceptions to this requirement, the following calibration frequencies will be required: 

  

	 	•	 	Class 1 Primary Flow Elements – Laboratory calibration per ASME PTC 6 – 2004 Standards (No re-calibration required) 

  

	 	•	 	Instrument PTs/CTs – Certification of class accuracy only 

  

	 	•	 	Passive Instrumentation (RTDs, Thermocouples, etc.) – Calibrated (or re-calibrated) within six (6) months of the test 

  

	 	•	 	Class 2 primary flow elements (e.g. RH spray, SH spray, etc.) and secondary flow elements- no calibration required 

  

	 	•	 	Electrical Metering (Class 1 primary) – within manufacturer’s recommended calibration frequencies 

  

	 	•	 	Electrical Metering (Class 2 primary) – no calibration required 

 The calibration frequency of other types of instruments not listed above requiring extreme measures (e.g. shaft speed pickup) for re-calibration shall also be exempt from the requirements for calibration or
re-calibration. Laboratory calibration of instrumentation prior to shipment is acceptable. Seller and Buyer shall mutually agree upon exceptions to this requirement. 
 In the event a test is postponed and the test equipment has not met the requirements of the calibration frequency, it shall be permissible to start the test and, as soon as practical and no more than 45 Days after
test completion, have the test instrumentation re-calibrated. The test procedures shall define the method of correction of test results in the event the subsequent calibration determines the presence of an instrument error from the initial
calibration.

	 	4.	All primary temporary instrumentation (as detailed in Table 1) will initially require “laboratory grade” calibrations, defined as a high accuracy calibration in a very
controlled environment. Re-calibration or re-ranging of this instrumentation may be performed in the field upon mutual agreement between Buyer and Seller. It is understood that the Class 2 primary flow elements will not be calibrated.

  

	 	5.	Post-test calibrations shall not be required unless the measured test data is considered suspect by any party to the test or the calibration frequency requirements have not been met
prior to the test. Post-test calibration data will only be used to adjust the measured test data if all parties to the test determine this is a valid correction. 

  

	 	6.	Calibration records should be made available to all parties for the instruments requiring calibration. 

  

	 	7.	In general, it shall be considered unnecessary to apply calibration data to measured pressures. However, the calibration data will be considered for all primary temperature
measurements as identified in Table 1. Water leg corrections for pressure and differential pressure measurements shall be made. 

  

	 	8.	Unless specifically stated otherwise, inspections of all flow elements will be done only if data is found to be suspect, and will be a mutual decision between all parties to the
test. If the parties to the test agree that an inspection is necessary, an inspection will most likely be completed using a borescope during a planned shutdown of sufficient duration. See section C.1 for feedwater flow discussion.

  

	 	9.	Un-calibrated primary instrumentation shall be manufactured in accordance with ISA, ISO, ASME or similar internationally recognized standard. 

  

	 	E.	Preparation and Operation of the Seller Equipment 

  

	 	1.	Not Used 

  

	 	2.	Steady state operation shall be based on the guidelines recommended by the ASME PTC 6 – 2004 Test Code for Steam Turbines. 

 However, the allowable deviation from rated conditions for STG exhaust pressure shall be expanded to accommodate the expected range of operation of the
condenser and cooling tower throughout the entire year. For the exhaust pressure, Seller shall submit a correction curve covering the range of expected operation for STG exhaust pressures. This correction curve will be used to correct the steam
turbine performance to reference conditions. 
  

	 	3.	The steam turbine performance shall be determined as the average of two four-hour test runs. 

  

	 	4.	Steam Turbine Degradation (Aging)

	 	a.	Buyer shall isolate the cycle to the extent practical, and within the limits of safe operation. However, the following small leakage flows are expected to be in operation around
certain valves to ensure safe operation during an emergency situation: 

 i. Warm up steam around the cold reheat to gland
steam seal system letdown valve 
 ii. Warm up steam around the HP bypass valve 
 iii. Warm up steam around the IP bypass valve 
 These small flows will be assumed to be negligible. Any other identified flows will be evaluated and the performance impact shall be considered; small flows with no performance impact will be deemed negligible. These valves will be
throttled to the extent possible. 
  

	 	b.	The Seller’s test procedure shall detail the plant valve line-up and other operating conditions not detailed above. The final decision to isolate any valves shall be by Buyer.
This information shall be communicated to the Seller before the commencement of the test program. 

  

	 	c.	Prior to testing, a test will be performed to quantify the total leakage from the cycle via a two hour hotwell drop test. Cycle isolation must be completed per the agreed upon cycle
isolation list provided in the Seller’s test procedure prior to commencement of this test. 

 The total measured
Unaccounted for Cycle Losses flow rate should be less than or equal to 0.25% of test throttle flow rate at full load. If it is determined that the total Unaccounted for Cycle Losses flow rate is greater than 0.25%, efforts will be made to locate and
fix the additional cycle losses, unless the parties mutually agree otherwise. The final “Unaccounted for Cycle Losses” flow rate will be calculated in the following manner; 
 Unaccounted for Cycle Losses = Measured Cycle Losses –Accounted for Cycle Losses.” 
 If the Unaccounted for Cycle Losses are still greater than 0.25% after exhausting all reasonable efforts to determine the source of the additional cycle
losses, both the Buyer and Seller need to come to a mutual agreement to continue the test program with a higher than expected Unaccounted for Cycle Loss (> 0.25%). If agreement is reached, the above equation for Unaccounted for Cycle Losses will
be used. 
  

	 	6.	All Unaccounted for Cycle Losses will be used in the adjustment of main steam flow to the steam turbine in the acceptance test calculations. 

  

	 	F.	Performance Calculation Methodology 

 The
performance test result calculation shall follow the general guidelines of the ASME PTC 6 test code, as modified by the items detailed herein.

 Option 1 (N2 packing is for HP-IP opposed flow turbines only) 
 The N2 internal packing flow will be determined by a “N2 Inference Method” test conducted by the Seller and witnessed by the Buyer. The excerpt
from the Steam Turbine Test Procedure concerning N2 Flow is shown below. 
 N2 Packing Leakage Test 
 In order to determine the actual HP turbine exhaust flow and the true IP turbine efficiency, the N2 packing leakage must be determined. The N2 packing
leakage is the steam which leaks from the first stage of the HP turbine to the IP turbine bowl along the N2 shaft packing. The steam turbine is designed to pass a given amount of steam flow to “cool” the first reheat stage during
operation. Depending on the packing clearances, and stage pressures, this flow may be somewhat greater than or less than the design flow on the contract heat balances. Determination of this flow reduces the test uncertainty associated with the steam
turbine performance. 
 The method used to determine the N2 packing leakage test is commonly referred to as the “Booth-Kautzmann”
method, or the “Temperature Inference Method”. This test requires that the unit operate at base load or near base load at different combinations of inlet temperatures to the HP and IP sections of the steam turbine. Typically, a test run is
conducted at a minimum of three different temperature conditions as outlined below. 
  

	 	•	 	Superheat and Reheat Temperatures Equivalent 

  

	 	•	 	Superheat Temperature. Approx. 50° F greater than Reheat Temperature. 

  

	 	•	 	Reheat Temperature Approx. 50° F greater than Superheat Temperature. 

 The temperature splits described above can usually be achieved by using the spray flows to attemperate the superheat and reheat steam temperatures. 
 Typically, in order to achieve the desired temperature split, it is recommended to conduct N2 packing test at approximately 75%-80% load. The duration of
each of these test runs should be at least 30 minutes, but will likely require much longer amount of time in between runs to change the superheat and reheat temperatures and achieve steady state conditions. No cycle isolation is required for these
test runs. 
 The boiler should be operated at steady load during entire N2 packing test. The N2 packing test will be conducted at the same
time as the bench mark test (if applicable). The test should be conducted at the highest attainable load, but no lower than 75% of the guaranteed load. The test should be conducted with the control valves in the wide-open position for all stop and
intercept/ control valves. 
 Option 2 
 The N2 packing leakage shall be calculated at as fixed percentage of HP throttle flow, based upon conditions at the reference conditions. The fixed percentage can be calculated from the Seller supplied heat balance at
the guarantee condition. 
  

	 	8.	Turbine throttle steam flow shall be determined as the boiler’s measured feedwater flow plus any additional spray water flow minus any unaccounted-for leakages in the steam
cycle.

	 	G.	Data Collection and Reduction 

  

	 	1.	All test data collected during the test shall be provided to Buyer as early as reasonably possible after the test. When data is available electronically, electronic files shall be
provided to all parties. If additional instruments have been installed by Seller for diagnostic purposes, then such data shall be made available to Buyer by Seller, unless Seller determines that such data is proprietary. 

  

	 	2.	Data which appears to be in error may be rejected after mutual agreement between the Buyer and Seller. 

  

	 	H.	Test Tolerance and Test Uncertainty 

  

	 	1.	The final test tolerance used to determine whether Seller has met guaranteed performance shall be based on a pre-determined commercial test tolerance. The commercial test tolerance
shall be as defined in Section 5, Appendix 4, Clause 7, B, d. 

  

	 	2.	A pre-test uncertainty calculation shall be performed to establish an estimate of the test uncertainty. A post-test uncertainty calculation shall not be performed if no deviation
from the conditions specified herein are found, except those caused by Seller. 

  

	 	3.	If there are no significant deviations from the assumptions made in this document, then the test tolerance specified in Section 5, Appendix 4, Clause 7, B, d will be used as
the test tolerance for evaluating the Seller’s performance against the performance guarantees. The test tolerance specified in Section 5, Appendix 4, Clause 7, B, d will be the minimum test tolerance to be applied as a band around the
measured Equipment Performance Guarantee values. 

 Should one or more of the provisions agreed upon herein not be incorporated
by Buyer, that in the reasonable opinion of the Buyer and Seller, materially increase the test uncertainty above the pre-test uncertainty estimate, then a post test uncertainty calculation shall be performed. The test tolerance shall be increased
above the commercial test tolerance defined in Section 5, Appendix 4, Clause 7, B, d to account for the test uncertainty increase between the pre-test and post-test uncertainty calculations. 
 However, if Buyer and Seller agree that there are adequate reasons for the test tolerance to be increased for reasons attributable to Buyer, and at the
same time there are aspects of the test that are being performed more accurately than specified in this document that result in a reduction in test uncertainty, then these provisions shall also be considered. The test provisions that lead to higher
than expected test uncertainty shall be offset against test provisions that lead to lower than expected test uncertainty. The net difference between these offsetting differences shall be used to adjust the test tolerance, provided that the ultimate
test tolerance value will not be lower than the value specified in Section 5, Appendix 4, Clause 7, B, d. 
 All test uncertainty
calculations shall be determined in general accordance with ASME PTC 19.1 – 1998.

	1.0	General - Liquidated Damages (LDs) Reasonable 

 The
Parties agree that Buyer would be damaged by Seller’s failure to meet the required dates (“Guaranteed Milestone Dates”) set forth in Articles 2, 3 and 4 of this Appendix 5 (including any failure to achieve Substantial Completion by
the date which is ninety (90) Days prior to the Guaranteed Substantial Completion Date which is attributable to Seller) and that Buyer’s actual damages in any such event would be extremely impracticable or impossible to calculate.
Accordingly, the Parties agree that Seller’s liability to Buyer for failure to achieve the specified dates shall be determined by and limited to amounts as specified below, which Seller agrees to pay to Buyer in such event as liquidated damages
and not as a penalty. 
 The Parties, having negotiated in good faith for such specific liquidated damages and having agreed that the amount
of such liquidated damages is reasonable in light of the anticipated harm caused by the breach or fault related thereto and the difficulties of proof of loss and inconvenience or nonfeasibility of obtaining any adequate remedy, are estopped from
contesting the validity or enforceability of such liquidated damages. 
 If any sum specified as liquidated damages fails as liquidated
damages for any reason, then Seller shall nonetheless be liable to pay general damages in respect thereof, provided that such general damages shall not exceed the subcap applicable to any liquidated damages that would have been payable in such
circumstances. 
 Except as provided herein, each item of liquidated damages appearing in Articles 2, 3 and 4 below shall apply separately and
independently of every other item of liquidated damages appearing in this Appendix 5. To the extent funds withheld by Buyer are not sufficient to pay any and all liquidated damages arising under this Agreement, Seller shall pay such liquidated
damages upon demand, after receipt of Buyer’s claim and invoice. 
 Payment of liquidated damages shall not relieve Seller from its
obligation to carry out and complete the Work in accordance with this Agreement and/or from any other duties, obligations or responsibilities Seller may have under this Agreement and, accordingly, shall not prejudice Buyer’s rights in the event
of the failure of Seller to comply with any such obligations, subject to the provisions of Section 5 (Special Conditions) Clause SC-30 (Limitation of Liability).

Equipment Delivery, subject to Buyer’s rights under Section 4 (General Conditions) Clause GC-9 (Termination for Default) and Section 5 (Special Conditions) Clause SC-4 (Expediting) and subject to Seller’s liability for payment of
other liquidated damages specified in Article 4.0 of this Appendix 5. 

  

	4.0	Guaranteed Substantial Completion Delay Liquidated Damages 

  

	4.1	If (a) Seller’s Equipment fails to achieve the performance levels necessary for the Facility to achieve Substantial Completion or (b) defects or deficiencies in the
Equipment prevent its operation, as required, to support Buyer’s start-up and commissioning of the Facility and its component equipment and systems (including Performance Test activities for the achievement of Substantial Completion) or
(c) the Equipment is unable to operate in support of the Performance Tests for Substantial Completion, and to the extent any of the foregoing causes delay in achieving Substantial Completion beyond the date that is ninety (90) Days prior
to the Guaranteed Substantial Completion Date (as such date may be extended from time to time under the EPC Contract), then (subject to provisions of Article 4.2 and the qualifications set forth below), Seller shall pay liquidated damages
(“Substantial Completion LDs”) as set forth below to Buyer for such delay to Substantial Completion beyond the date that is ninety (90) Days prior to the Guaranteed Substantial Completion Date (the stipulated amounts to be pro rated
for any portion of a Day): 

  

			
	 Days Late attributed to Seller
	  	 Substantial Completion LDs per Day

	For Days of delay in achieving Substantial Completion occurring 1 to 90 Days prior to the Guaranteed Substantial Completion Date	  	1 to 90 Days $***
		
	For Days of delay in achieving Substantial Completion occurring on or after the Guaranteed Substantial Completion Date	  	1 Day and beyond $***

  

	4.2	Subject to Article 4.3 below, Buyer will provide reasonable access to the Equipment for a period of seventy-five (75) Access Days for the start up and commissioning of the
Equipment commencing from the Turbine Roll and any additional time, if available, within the overall start up and commissioning period from the commencement of Turbine Roll before Seller may become liable for Substantial Completion Liquidated
Damages for delays in achieving Substantial Completion, which does not compromise or interfere with other commissioning activities.

	4.3	Such seventy-five (75) Access Day period shall be reduced by the number of Days that the cumulative impact of Equipment Delivery Delay(s) causes Turbine Roll to be delayed. In
addition, in the event that all other equipment and systems in the Facility are ready to support Turbine Roll and a defect(s) or deficiency(ies) in the Equipment is the primary cause of a delay in the Turbine Roll date, such seventy-five
(75) Day period also shall be reduced one Day for each Day of delay caused primarily by such defect(s) or deficiency(ies) in the Equipment as aforesaid. 

  

	4.4	If Buyer is unable to provide such period of seventy-five (75) Access Days (or such lesser period as provided in Article 4.3 above), then (notwithstanding that the date for
Guaranteed Substantial Completion Date may have occurred) Days of delay will not be allocated to the Seller (hence no liability to the Buyer for Substantial Completion LDs shall apply) until Buyer has provided it with seventy-five (75) Days (or
such lesser period as provided in Article 4.3 above) for the start up and commissioning of the Equipment from the Turbine Roll date. 

  

	4.5	For the purposes of calculating the number of Access Days for the start up and commissioning of Equipment, if Seller has access to the Equipment to perform start up related
activities required for operation and the achievement of Substantial Completion, that Day shall be counted as an Access Day for the start up and commissioning of Equipment. 

  

	4.6	An “Access Day” shall be any day during which the Equipment is available for performance of check out, balancing, tuning (including part load and integrated base, or other
work start-up related activities) required so that Equipment will support the achievement of Substantial Completion or the Performance Guarantees. In the event that conflicting Facility activities or circumstances arise that prevent the performance
of the necessary startup related activities in the order and manner reasonably required by Seller, and that event causes a delay for that Day, an Access Day shall not have occurred. Notwithstanding the above, there shall be an Access Day if Seller
has access to the Equipment, the required lubricants, operating supplies and third party interconnections are available, Owner’s operators are available as necessary to operate the Equipment as required and Buyer’s craft labor are
available as agreed to support Seller’s startup activities. 

  

	4.7	For the avoidance of any doubt, if Buyer fails to make the Equipment available as contemplated by the preceding paragraph that Day will not be counted as an Access Day for the start
up and commissioning of Equipment. Conversely, if Buyer makes the Equipment available as contemplated by the preceding paragraph and Seller elects not to perform startup activities, that Day will be counted as an Access Day for the start up and
commissioning of Equipment. 

  

	4.8	It shall be understood that all Parties will actively participate in the coordination and scheduling of startup related activities to achieve Substantial Completion in an organized,
effective and efficient manner. 

  

	4.9	Further understandings in respect of the Substantial Completion LDs are set out in paragraphs (i) through (v) below:

	 	(ii)	Buyer shall give written notice to Seller of any determination of responsibility under this Article 4.0, and of any resulting assessment and obligation to pay liquidated damages to
Buyer on a weekly basis. Buyer will promptly provide Seller with full details of all relevant calculations and with copies of all relevant schedules, correspondence and other documents upon which such determination, assessment and attribution were
based. 

  

	 	(iii)	With respect to Substantial Completion LDs for the period after the Guaranteed Substantial Completion Date, if Owner does not recover or seek to recover from Buyer liquidated
damages for failure to achieve Substantial Completion under the Prime Contract, Buyer shall not be entitled to recover Substantial Completion LDs from Seller under this Agreement. 

  

	 	(iv)	In no event shall the Substantial Completion LDs recoverable from Seller in respect of delay to Substantial Completion after the Guaranteed Substantial Completion Date be in excess
of the amount of Substantial Completion LDs recovered or sought from Buyer by Owner for failure to achieve Substantial Completion under the Prime Contract. 

  

	 	(v)	To the extent that a delay in achievement of Substantial Completion is caused by one or more previous delays in Delivery of Equipment (“Equipment Delivery Delays”) then
the following will apply: 

  

	 	(i)	in the event that the cumulative impact of such Equipment Delivery Delay(s) on achievement of Substantial Completion is determined by Buyer, acting reasonably, to be thirty
(30) Days or less then the Equipment Delivery LDs previously paid shall be treated as Buyer’s exclusive remedy for such Equipment Delivery Delay(s), subject to Buyer’s other rights under Section 4 (General Conditions) Clause GC-9
(Termination for Default) and Section 5 (Special Conditions) Clause SC-4 (Expediting) and Seller shall have no liability for Substantial Completion LDs on account thereof; 

  

	 	(ii)	in the event that the cumulative impact of such Equipment Delivery Delay(s) on achievement of Substantial Completion is determined by Buyer, acting reasonably, to be more than
thirty (30) days then Seller shall be fully liable for payment of Substantial Completion LDs for the full impact of such Equipment Delivery Delay(s) on achievement of Substantial Completion, in addition to the Equipment Delivery LDs previously
paid, but Buyer will credit the amount of such Equipment Delivery LDs paid on account of such Equipment Delivery Delay(s) against Seller’s liability for Substantial Completion LDs.

 GENERAL CONDITIONS 
  

	GC-1	ENTIRE AGREEMENT 

  

	1.1	This Agreement embodies the entire agreement between Buyer and Seller. The Parties shall not be bound by or liable for any statement, representation, promise or understanding not
set forth herein. Nothing contained in proposals, correspondence, discussions, order acknowledgements or other of Seller’s forms has any effect on this Agreement unless specifically incorporated herein. 

  

	1.2	No modifications to this Agreement shall be valid unless reduced to writing and signed by both Parties pursuant to Clause GC-2 (Changes). 

  

	GC-2	CHANGES 

  

	2.1	Buyer, through its authorized procurement representative, may at any time direct, in writing, changes, including but not limited to changes in any one or more of the following:
(1) drawings or specifications; (2) additions to or deletions from quantities ordered; (3) Delivery schedule; (4) method of shipment or packing; (5) place of Delivery. If any such change causes an increase or decrease in the
cost or timing required to provide the Equipment, or otherwise affects Seller’s ability to meet its obligation, an equitable adjustment shall be made in the Agreement Price or Delivery schedule and/or other relevant terms and the Agreement
shall be modified by written amendments or revisions executed by authorized representatives. Any request by Seller for adjustment under this Clause GC-2 (Changes) must be asserted promptly by written notice to Buyer’s authorized representative
and in no case later than within twenty (20) Days from the date of receipt by Seller of the notification of a change, unless the Parties mutually agree to extend the time required to assess and determine the resulting impact. Buyer shall
respond to Seller’s request for adjustment within thirty (30) days of receipt of Seller’s notice. However, nothing in this clause shall excuse Seller from proceeding with the order as changed unless Seller notifies Buyer in writing
within the aforementioned thirty (30) Day Period that such change is not technically feasible. Failure by Seller to timely give the required notice hereunder will preclude Seller’s right to request any adjustment. In the event that Buyer
and Seller are not able to reach agreement on a firm price for a Buyer directed change after good faith negotiations by the Parties or in case of an emergency endangering life or property or the Facility has ceased operation or is materially and
adversely affected in its operation requiring immediate corrective action, Seller will proceed with implementation of the change on a time and materials basis, including a reasonable profit. In such event, Seller agrees to provide in a timely manner
such documentation as is reasonably sufficient for Buyer to determine the accuracy of impact of the change on a time and material basis. 

  

	2.2	If this Agreement requires Buyer to review and comment on Seller’s technical documents, Seller shall submit, within twenty five (25) Days from the date of Seller’s
receipt of such comments, any request for adjustment resulting from implementation of Buyer’s comments. No adjustment will be made hereunder unless Buyer, through its authorized procurement representative, confirms the change in writing.

  

	2.3	A Change in Law affecting Seller’s Work under this Agreement (except for changes relating to taxes to be paid by Seller) and occurring after the Effective Date shall be
considered a change and will be handled in accordance with Clause GC-2.1 above, provided that Seller gives notice to Buyer of such Change in Law within ten (10) Days of 

  

					
		 	Page 2 of 10	 	
	By Seller:                     	 		 	By Buyer:                     

 Seller becoming aware of said change or event, unless the Parties mutually agree to extend the time
required to assess and determine the resulting impact. Seller shall also give notice to Buyer of such Change in Law within ten (10) Days of when it would be commercially reasonable to expect that Seller should have become aware of such change
or event, however, to the extent such notice is delayed, Seller’s remedies shall be impacted only to the extent that Buyer or Owner have suffered any damage as a result of such delay. 
  

	2.4	Suspension instructed by Buyer pursuant to Clause GC-7 (Suspension) will also be treated as a change and will be handled in accordance with Clause GC-2.1 above, unless such
suspension arises as a result of any fault, defect or other failure to perform which is attributable to Seller. 

  

	2.5	A Force Majeure event will be treated as a change pursuant to Clause SC-36. The affected Guaranteed Milestone Dates shall be adjusted by the period of time, if any, that Seller is
actually and demonstrably delayed in the critical path activities as a result of the impact of such an event of Force Majeure and the Agreement Price shall be adjusted for the actual and demonstrable costs incurred as a result of the impact of one
or more Force Majeure events exceeding the first two million dollars ($2,000,000) in the aggregate. 

  

	GC-3	DELIVERY 

  

	3.1	Timely performance and Delivery of Seller’s obligations shall be in accordance with the Guaranteed Milestone Dates. However, to the extent Buyer’s failure to fulfill any
of its material obligations under this Agreement, except payment obligations, actually and demonstrably delays Seller in the performance of its critical path activities and such delay causes Seller to incur a material cost increase in its
performance, Seller shall be entitled to request a change including an equitable adjustment to the affected Guaranteed Milestone Date(s) and/or an equitable adjustment to the Agreement Price, except to the extent that Seller fails to exercise good
faith efforts to mitigate the impact of such Buyer delay and provided in any event that Seller must give notice to Buyer within five (5) days after the occurrence of such Buyer delay. Such notice will specify the nature of the occurrence and
the reason(s) why Seller believes additional time should be granted and the length of the delay and/ or additional costs occasioned by reason of such Buyer delay. Strict compliance with this Clause GC-3 (Delivery) is a condition precedent to any
entitlement to an extension of the affected Guaranteed Milestone Date(s) and/or an adjustment to the Agreement Price. Failure by Seller to timely give the required notice hereunder will preclude Seller’s right to invoke the protection of this
Clause GC-3 (Delivery) to the extent Buyer is prejudiced by such failure. Seller shall use its reasonable best efforts to minimize or avoid the delay caused by Buyer delay and the initial notice provided by Seller shall describe in detail the
efforts of Seller that have been or are going to be made in this regard. Upon mutual agreement of the Parties to Seller’s entitlement for an equitable adjustment to the affected Guaranteed Milestone Date(s) and/or an adjustment to the Agreement
Price, this Agreement shall be modified by written amendment or revision executed by the Parties’ authorized representatives. 

  

	GC-4	TITLE AND RISK OF LOSS

 of such Work into the Project, whichever occurs earlier. In order to protect Buyer or Owner’s
interest in items of Work with respect to which title has passed to Buyer or Owner but which remains in the possession of Seller, Seller shall segregate such items of Work and shall take or cause to be taken all steps necessary under the Applicable
Laws to maintain Buyer’s or Owner’s title and to protect Buyer or Owner against claims by other parties with respect thereto. 
 Notwithstanding the foregoing, Seller warrants that upon passage of title to the Work in accordance with this Clause GC-4 (Title and Risk of Loss), Buyer or Owner will have good and indefeasible title to such Work, and such Work will not be
subject to any lien, privilege, security interest or other defect in title. If any Work is replaced, title in the replacement Work shall vest in Buyer or Owner upon the earliest of (1) payment therefor, (2) its shipment to the Jobsite or
(3) incorporation into the Project. IN THE EVENT OF ANY NONCONFORMITY WITH THE FOREGOING WARRANTY, SELLER, AT ITS OWN EXPENSE, UPON WRITTEN NOTICE OF SUCH FAILURE, SHALL INDEMNIFY OWNER AND BUYER FROM THE CONSEQUENCES OF AND DEFEND THE TITLE TO
SUCH WORK AND IF, NECESSARY, SHALL PROMPTLY REPLACE SUCH WORK AND ANY OTHER AFFECTED PORTION OF THE WORK, AND SUCH OBLIGATION SHALL SURVIVE THE EXPIRATION, CANCELLATION OR TERMINATION OF THIS AGREEMENT, INCLUDING THE WARRANTY PERIOD. 
  

	4.2	Notwithstanding anything to the contrary in this Agreement, Seller shall be responsible for and shall bear any and all risk of loss or damage to the Equipment and any materials
included in the Work until Delivery to the Jobsite. Upon such Delivery to the Jobsite, Seller shall cease to bear the risk of loss or damage; provided however, that any loss or damage, whenever occurring, which results from Seller’s
nonconforming packaging or crating or from any defect in such Equipment or such materials shall be borne by Seller. 

  

	GC-5	INFRINGEMENT 

  

	5.1	SELLER SHALL, AT ITS OWN EXPENSE, FULLY HOLD HARMLESS, INDEMNIFY AND DEFEND INDEMNIFIED PARTIES UNDER THIS AGREEMENT AGAINST ANY CLAIM, SUIT, ACTION, PROCEEDING OR INVESTIGATION
WHICH IS BASED UPON A CLAIM, WHETHER RIGHTFUL OR OTHERWISE, THAT ANY EQUIPMENT, OR ANY PART THEREOF, OR AN OTHER ITEMS OR SERVICES FURNISHED BY SELLER UNDER THIS AGREEMENT CONSTITUTES AN INFRINGEMENT OF ANY DOMESTIC OR FOREIGN PATENT, COPYRIGHTS OR
OTHER INTELLECTUAL PROPERTY, TRADEMARK, PROPRIETARY OR CONFIDENTIAL RIGHTS, OR UNAUTHORIZED DISCLOSURE OR USE OF ANY TRADE SECRET AND SELLER SHALL PAY ALL RESULTING DAMAGES INCLUDING LEGAL EXPENSES AS PROVIDED IN CLAUSE GC-5.3 BELOW. IF, IN ANY SUCH
CLAIM, SUIT, ACTION, PROCEEDING OR INVESTIGATION, A TEMPORARY RESTRAINING ORDER OR PRELIMINARY INJUNCTION IS GRANTED, SELLER SHALL MAKE EVERY REASONABLE EFFORT, BY GIVING A SATISFACTORY BOND OR OTHERWISE TO SECURE THE SUSPENSION OF THE INJUNCTION OR
RESTRAINING ORDER. In case said Equipment, or any part thereof, are in such suit or action held to constitute infringement and/or use is permanently enjoined, Seller shall, at its own expense, subject to the following provisions, either procure for
Buyer and Owner an irrevocable, royalty-free license to continue using such Equipment, or with Buyer’s prior written approval which shall not be unreasonably withheld, replace same with substantially equal but noninfringing Equipment or modify
them so they become noninfringing, provided that no such replacement or modification shall in any way amend or relieve Seller of its Equipment Performance Guarantees, warranties, guarantees or other obligations set

 forth in this Agreement. Further, Seller agrees that it shall not settle any suit for which it is
providing indemnity under this Clause GC-5 (Infringement) without the prior consent of the Indemnified Parties, such consent not to be unreasonably withheld so long as such settlement completely discharges or releases the indemnifiable claims
against the Indemnified Parties and does not impose by way of consent decree, injunction or otherwise any restraint or limitations on such parties; operations or upon the operation or other use of the Facility. Buyer acknowledges it may be required
to enter into certain license agreements, which shall be provided by Seller at no additional cost to Buyer or Owner, with regard to the use of Seller proprietary computer software. 
  

	5.2	The preceding paragraph shall not apply to any Equipment, or any part thereof, manufactured to Buyer’s or Owner’s detailed design or modifications to any Equipment or part
thereof made by Buyer or Owner. As to such Equipment or part, Seller assumes no liability whatsoever for infringement. 

  

	5.3	Seller’s obligation to hold Indemnified Parties harmless under this Clause GC-5 (Infringement) includes responsibility for paying reasonable legal expenses and other direct
costs incurred by Indemnified Parties in connection with the defense and settlement of any claim or suit within the scope of this clause. In connection with this indemnity: (a) Indemnified Parties shall promptly notify Seller of any claim or
suit or proceeding involving Indemnified Parties in which such infringement is alleged, and Indemnified Parties shall permit Seller to control completely the defense or compromise of any such allegation of infringement in which case Seller may
select counsel after consultation with Indemnified Parties, provided that (i) Buyer is consulted and kept reasonably informed of the claims, litigation, and negotiations, (ii) Indemnified Parties shall be entitled at Indemnified
Parties’ expense to participate in such defense, and (iii) no compromise shall be adverse to Indemnified Parties without such party’s consent and (b) Buyer shall render such reasonable assistance at Seller’s cost in the
defense thereof as Seller may require. If the defendants in any such action include both Seller and an Indemnified Party and the Indemnified Party shall have reasonably concluded that there may be legal defenses available to it which are in conflict
with those available to Seller, and that such conflict materially prejudices the ability of the counsel selected by Seller to represent both Parties, such Indemnified Party shall have the right to select separate counsel reasonably acceptable to
Seller to participate in the defense of such action on its own behalf at Seller’s expense. 

  

	5.4	If any claim, suit, action, proceeding or investigation arises as to which the indemnity provided for under this Clause GC-5 (Infringement) hereof may apply and Seller, after being
given written notice by the Indemnified Party promptly upon becoming aware of such claim, suit, action, proceeding or investigation, fails to assume the defense of, or to diligently defend, such claim, action, proceeding or investigation, then the
Indemnified Party may, upon giving prior notice thereof to Seller, at the expense of Seller, contest (or, with the prior written consent of Seller, settle) such claim. 

  

	5.5	Notwithstanding any proprietary legends or copyright notices to the contrary, Indemnified Parties may copy or reproduce documents and information furnished by Seller in connection
with Seller’s proposal and with this Agreement and distribute such copies or reproductions to others for the limited purposes of designing, financing, constructing, altering, operating, maintaining or licensing the Project. SELLER IS
RESPONSIBLE FOR OBTAINING NECESSARY PERMISSION AND RELEASES FROM ANY THIRD PARTIES PLACING PROPRIETARY RIGHTS OR COPYRIGHTS ON SUCH DOCUMENTS OR INFORMATION AND SHALL, AT ITS OWN EXPENSE, HOLD

 HARMLESS AND DEFEND INDEMNIFIED PARTIES AGAINST ANY AND ALL CLAIMS, SUITS, ACTION, PROCEEDINGS OR
INVESTIGATIONS BASED UPON A CLAIM WHETHER RIGHTFUL OR OTHERWISE THAT A PROPRIETARY RIGHT OR COPYRIGHT HAS BEEN INFRINGED BY COPYING, REPRODUCTION, DISTRIBUTION OR USE BY INDEMNIFIED PARTY. 
  

	5.6	Seller agrees that all documents prepared by Seller which are delivered to Buyer in the performance of the Agreement shall be the sole and exclusive property of Buyer, except that
(a) Seller shall retain the right to utilize such documents for reference in its general practice and (b) to the extent that Seller has a pre-existing patent, copyright, trade secret, or other proprietary interest in any documents to be
provided under the Agreement, Seller hereby grants Buyer and Owner and their respective Affiliates an irrevocable, nonexclusive, royalty-free, license to internally reproduce, distribute, and use such proprietary documents, including the preparation
of derivative works for internal use but without the right to disclose such proprietary documents to any third parties (other than to its Affiliates and its and their respective employees, directors, officers, managers, partners, accountants,
attorneys, Financing parties, agents and consultants) unless (i) such third party is subject to written confidentiality requirements pursuant to Section 5, SC-22 (Nondisclosure); or (ii) such disclosure is required for purposes of
designing, financing, constructing, altering, operating, maintaining or licensing the Project. Such license shall be freely assignable (x) to any Financing Party and (y) any Person to which the Project is sold or otherwise transferred.
Seller agrees that all documents, as well as any drawings, tracings, specifications, calculations, memoranda, data, notes and other materials which are supplied by Buyer and come into the possession of Seller, shall be used solely with respect to
this Project and shall, except for Seller’s file copies, be delivered to Buyer upon Final Completion. Nothing in the foregoing gives Buyer or Owner or any third party the right to manufacture or remanufacture any Equipment or parts of any
Equipment provided by Seller including vendor items. Buyer acknowledges it may be required to enter into certain license agreements, which shall be provided by Seller at no additional cost to Buyer or Owner, with regard to the use of Seller
proprietary computer software provided during the execution of this Agreement. 

  

	GC-6	COMPLIANCE 

  

	6.1	Seller warrants that all Equipment shall have been produced, sold, delivered and furnished in strict compliance with all Applicable Laws to which the Equipment is subject. Seller
shall execute and deliver to Buyer any documents as may be required to effect or to evidence such compliance. 

  

	6.2	SELLER HEREBY AGREES TO INDEMNIFY, DEFEND AND HOLD INDEMNIFIED PARTIES HARMLESS FROM AND AGAINST ANY AND ALL CLAIMS, LEGAL ACTIONS, FINAL JUDGMENTS, REASONABLE ATTORNEYS’ FEES,
CIVIL FINES AND ANY OTHER PENALTIES WHICH ANY OF THEM MAY INCUR AS A RESULT OF THE SALE OR DELIVERY TO BUYER HEREUNDER OF EQUIPMENT WHICH DOES NOT MEET ALL REQUIREMENTS OF SUCH LAWS AND REGULATIONS. 

  

	6.3	Seller shall comply with all applicable export or import rules and regulations. When required by the Agreement shipping/delivery terms, Seller is to obtain any necessary export
license in a timely manner to avoid shipment delays. When Buyer is required by the Agreement shipping/delivery terms to obtain any necessary export license, or to meet the import rules and regulations of the destination country, Seller is to timely
provide all necessary assistance to Buyer and its agents. SELLER SHALL INDEMNIFY, DEFEND AND HOLD HARMLESS INDEMNIFIED PARTIES FROM ANY PENALTIES, SUITS,

 LIABILITIES OR COSTS (INCLUDING ATTORNEY FEES) CAUSED BY SELLER’S FAILURE TO COMPLY WITH APPLICABLE
EXPORT AND IMPORT RULES AND REGULATIONS OR TO COMPLY WITH ITS EXPORT AND IMPORT OBLIGATIONS SET FORTH IN THIS AGREEMENT. 
  

	6.4	Seller shall comply, and shall cause its Subsellers to comply, with all Applicable Laws in effect from time to time relating to the Work, the Equipment and/or the Project, and shall
give all applicable notices pertaining thereto. Seller shall ensure that the Equipment, as designed, engineered and, manufactured, complies and when fully operated is capable of complying with all Applicable Laws. 

  

	6.5	Seller agrees to comply with all Applicable Laws regarding the import or export of technical data or information or any product based thereon and shall not ship or communicate or
allow to be shipped or communicated, either directly or indirectly, any technical data or information or any product based thereon in connection with the Work to any country or from any country to or from which such shipment or communications is
prohibited by Applicable Law. 

  

	GC-7	SUSPENSION 

  

	7.1	Notwithstanding any other provisions of this Agreement, Buyer may at any time suspend Seller’s performance upon written notice of such suspension indicating the effective date
of such suspension. Thereafter, Seller shall promptly resume performance as directed by Buyer specifying the effective date of resumption of suspended performance. In the event of such suspension (unless such suspension arises as a result of any
fault, defect or other failure to perform which is attributable to Seller), Seller shall be entitled to reimbursement for additional costs reasonably and necessarily incurred by Seller in effectuating such suspension (provided Seller shall use all
reasonable efforts to minimize such suspension costs), to the extent that such additional costs are actually incurred, if claimed within thirty (30) days after resumption of performance. During any such suspension, the reasonably demonstrated
suspension costs incurred by Seller shall be invoiced monthly and paid within sixty (60) days of receipt of such invoice (unless such suspension arises as a result of any fault, defect or other failure to perform which is attributable to
Seller). 

  

	7.2	In the event that the period of a suspension instructed by Buyer pursuant to Clause GC-7.1 (unless such suspension arises as a result of any fault, defect or other failure to
perform which is attributable to Seller) exceeds a period of three hundred sixty five (365) consecutive Days, except for suspensions which may be attributable to Force Majeure, Seller may, at its sole option, request that Buyer terminate the
Agreement in accordance with Clause GC-8, or request that the terms of this Agreement affected by such suspension be renegotiated. 

  

	7.3	If Seller is prevented from achieving a milestone event triggering a progress payment, because of a suspension (unless such suspension arises as a result of any fault, defect or
other failure to perform which is attributable to Seller), then Seller shall be entitled to invoice for payment on a prorata basis for reasonably demonstrated actual work completed (less payments already received) at the date such milestone payment
would have become invoiceable had Seller achieved the milestone event on such date and Buyer shall pay such amount.

	GC-8	TERMINATION FOR CONVENIENCE 

  

	8.1	Seller’s performance under this Agreement may be terminated by Buyer for its convenience in accordance with this clause in whole, or, from time to time in part whenever Buyer
shall elect. Any such termination shall be effected by delivery to Seller of a notice of termination specifying the extent to which performance under the Agreement is terminated, and the date upon which such termination becomes effective. Upon
receipt of any such notice, Seller shall, unless the notice requires otherwise: (1) immediately discontinue work on the date and to the extent specified in the notice; (2) place no further orders for materials or services other than as may
be necessarily required for completion of any portion of the Work that is not terminated; (3) promptly make every commercially reasonable effort to obtain cancellation on terms satisfactory to Buyer of all contracts with Subcontractors unless
Seller is directed by Buyer to take other actions with respect to the same which may include assignment of all or some of those contracts to Owner (or to Owner’s designee, which may be any affiliate or any third party purchaser) on terms
satisfactory to such assignee; and (4) assist Buyer upon request in the maintenance, protection, and disposition of property acquired by Buyer under this Agreement. For the elimination of doubt, only Buyer may terminate for convenience.

  

	8.2	After notice of termination, Buyer shall pay to Seller, as further provided in Section 5 Clause SC-19.1 (Termination Payment Schedule), as full compensation the sum of the
following amounts (which shall not be greater than the amounts identified in Section 5, Appendix 7 at the time of effectiveness of termination): 

 (i) all amounts due and not previously paid to Seller for Equipment completed in accordance with this Agreement prior to such notice, and for Work thereafter completed as specified in such notice; 
 (ii) the actual amount plus reasonable profit for any Equipment then ordered and/or in production, provided that no such adjustment shall be made in favor
of Seller with respect to any Equipment which is Seller’s standard stock; and 
 (iii) the actual amount of settling and paying claims
arising out of the cancelled contracts. 
  

	8.3	The total sum to be paid to Seller under this Clause GC-8 (Termination for Convenience) shall not exceed the Agreement Price as reduced by the amount of payments previously made by
Buyer under the Agreement and as further reduced by the portion of the Agreement Price attributable to Work not terminated, and will not include any consideration for loss of anticipated profits on terminated Work, all claims for which Seller agrees
to waive. 

  

	GC-9	TERMINATION FOR DEFAULT 

  

	9.1	Buyer may terminate the whole or any part of Seller’s performance under this Agreement in any one of the following circumstances; (1) if Seller substantially fails to make
Delivery of the Equipment or to perform within the time specified herein or any agreed extension thereof; or (2) if Seller delivers nonconforming Equipment subject to the cure period defined in this paragraph; or (3) if Seller fails to
provide adequate assurance of Seller’s ability to meet the quality standards of this Agreement; or (4) if Seller abandons or fails to perform any of the other material provisions of this Agreement in accordance with its terms or fails to
make progress as to endanger performance of this Agreement; or (5) if Seller shall commence a voluntary case or other proceeding seeking liquidation, reorganization or other relief with respect to itself or its debts under any bankruptcy,
insolvency or other similar law now or hereafter in effect, becomes insolvent, does not pay its debts as they become due or makes an assignment for the benefits of creditors; 

  

					
		 	Page 8 of 10	 	
	By Seller:                     	 		 	By Buyer:                     

 or (6) if Seller makes a material representation which is false or misleading in any material
respect when made; or (7) if Seller violates any Applicable Law with regard to this Agreement; or (8) if Seller assigns or transfers this Agreement (or any right or interest herein) in breach of Clause SC-13 (Assignment); or (9) if
insolvency, receivership, reorganization, or bankruptcy or similar proceedings are commenced against Seller and such proceeding shall remain undismissed or unstayed for a period of Sixty (60) Days; or (10) the failure of Seller to deliver
the parent company guarantee in accordance with Clause SC-26.1 (Parent Company Guarantees). Except for (5) or (6) or (8) or (9) for which no further notice shall be required or cure period allowed, in the event of any such
failure, Buyer will provide Seller with written notice of the nature of the failure and Buyer’s intention to terminate for default. Except for (5) or (6) or (8) or (9) or (10), for which no cure period is allowed, in the
event Seller does not commence implementation of reasonable corrective action within ten (10) days of such notice or diligently pursue such action to completion within seventy five (75) days of such notice, Buyer may by written notice
terminate this Agreement. With respect to (10), Buyer may by ten (10) days prior written notice terminate this Agreement. Upon termination by Buyer, Seller’s liability to pay any liquidated damages shall end and Buyer shall be entitled to
its remedies set forth in Clause 9.2 below provided that the foregoing shall not relieve Seller from liability for any liquidated damages which have accrued as of the date of termination. 
  

	9.2	In the event Buyer terminates this Agreement in whole or in part as provided in this Clause GC-9 (Termination for Default), Buyer may either (1) procure, under such terms and
in such manner as Buyer may deem appropriate, items of equipment which are similar to the items so terminated and Seller shall be liable to Buyer for any additional costs for such similar equipment and related services or complete the Work with
respect to the terminated items of Equipment and the remaining scope of Work; or (2) exercise any other rights or remedies available to Buyer at law or in equity subject to Clause SC-30 (Limitation of Liability) (including demanding damages and
payments from Seller); provided, that Seller shall continue the performance of this Agreement to the extent not terminated under the provisions of this Clause GC-9 (Termination for Default). 

  

	9.3	Seller agrees to assist Buyer in the event that re-procurement action is necessary or Buyer elects to complete the remaining Work as a result of default, by co-operation in the
transfer of information, in the disposition of Work in progress or residual material, and in the performance of other reasonable requests made by Buyer. 

  

	9.4	If, after notice of termination of this Agreement, it is determined for any reason that Seller was not in default under the provisions of this clause, or that the default was
excusable under the provisions of this Agreement, the rights and obligations of the Parties shall be the same as if the notice of termination had been issued pursuant to Clause GC-8 (Termination for Convenience). 

  

	GC-10	NON WAIVER 

  

	10.1	Failure by Buyer to insist upon strict performance of any of the terms and conditions hereof, or failure or delay in exercising any rights or remedies provided herein or by law, or
to properly notify Seller in the event of breach, or the acceptance of or payment for any Equipment hereunder, or review of design, shall not release Seller from any of the warranties or obligations of this Agreement and shall not be deemed a waiver
of any right of Buyer to insist upon strict performance hereof or a waiver of any of it rights or remedies as to any such Equipment regardless when shipped, received or accepted, or as to any prior or subsequent default hereunder, nor shall any
termination of this Agreement by Buyer operate as a waiver of any of the terms hereof.

	10.2	A requirement that a Seller-furnished document is to be submitted for or subject to “Authorization to Proceed”, “Approval”, “Acceptance “,
“Review”. “Comment” or any combination of such words or words of like import shall mean, unless the Agreement clearly indicates otherwise, that Seller shall, before implementing the information in the document, submit the
document, obtain resolution of any comments and Buyer’s authorization to proceed. Such review shall not mean that a complete check will be performed. Authorization to proceed shall not constitute acceptance or approval of design details,
calculations, analysis, tests, or construction methods or materials developed or selected by Seller and shall not relieve Seller from full compliance with requirements of this Agreement. 

  

	GC-11	APPLICABLE LAW 

  

	11.1	The rights and obligations of the Parties to this Agreement shall be governed by and construed in accordance with the laws of the State of Texas, without reference to conflicts of

entitled “Backcharges”. 

  

	SC-11	BACKCHARGES 

  

	11.1	In the event the Seller’s Work or Equipment is found to be defective as to workmanship or materials or not to be in conformance with this Agreement or any rework of the
Equipment is required by Buyer as a result of deficient technical advisory services rendered by Seller, it is the responsibility of Seller to promptly correct any deficiency when so directed. Buyer will take reasonable measures to discover such
noncompliance as quickly as practical; however, failure to do so shall in no way relieve Seller of its responsibility during the term of this Agreement and during the Warranty Period to promptly make such modifications as are required.

  

	11.2	If upon being notified in writing by Buyer of Seller’s deficient Work or Equipment, and having been directed to commence or correct the deficient Work or Equipment by specific
dates or other time periods agreed to by Buyer depending on the effect of such deficiency, Seller states its inability or unwillingness to comply or Seller fails to commence or correct the deficient Work or Equipment by such specific dates, then
Buyer shall proceed to accomplish the corrective work by the most expeditious means available to it and shall be entitled to backcharge Seller for the cost of the required work. The cost categories for which Seller is liable hereunder are the same
as those prescribed in Special Conditions Clause SC-6 entitled “Warranties”. 

  

	11.3	The cost of such backcharge work provided for herein or elsewhere in this Agreement shall be computed as follows: 

  

	 	A.	Engineering and other Home office nonmanual labor and field nonmanual labor shall be charged at $100/hr valid until the end of 2007 and thereafter escalated at 5% per year.

  

	 	B.	Manual labor shall be charged at $50/hr valid until the end of 2007 and thereafter escalated at 5% per year.

 signed authorization to proceed. Regardless of Seller’s willingness to provide such written
authorization, the Buyer, when forced to proceed with the work, upon completion of the work will invoice the Seller for actual costs incurred, computed as shown above, or withhold such sum from funds still due the Seller under this Agreement.

  

	11.5	In the event the Buyer or Owner have to expend additional time performing expediting, inspection or engineering activities because Seller states (or by its actions indicates) its
inability or unwillingness to complete the Work in accordance with the terms of this Agreement, Buyer or Owner shall proceed to perform additional expediting, inspection or engineering to facilitate completion. This action will be taken using
Buyer’s or Owner’s personnel or agents and Buyer will back charge Seller for the cost of the work at a rate of US 150 Dollars ($150) per hour (valid until the end of 2007 and thereafter escalated at 5% per year) plus actual and
reasonable expenses.

	12.1	Before starting Work, Seller shall designate in writing an authorized representative, project manager and project engineer acceptable to Buyer and Owner to represent and act for
Seller and shall specify any and all limitations of such representative’s authority. During periods when Work is suspended, arrangements shall be made for an authorized representative acceptable to Buyer for any emergency Work that may be
required. All written communications given to the authorized representative by Buyer shall be binding on Seller in accordance with this Agreement. Buyer shall designate in writing one or more representatives to represent and act for Buyer and to
receive communications from Seller. Notification of changes of authorized representatives for either Seller or Buyer shall be provided in advance, in writing, to the other Party.

any such assignment without such written consent shall be null and void. 

  

	13.2	Notwithstanding Clause SC 13.1, upon written notice to Buyer, Seller may, without such express written consent, assign compensation due or to become due under this Agreement,
provided that any assignment of compensation shall be subject to proper set-offs under this Agreement in favor of Buyer, any deductions provided for in this Agreement, and any assurances requested by Buyer.

rating by Standard and Poor of at least BBB-; or (iii) collaterally assign this Agreement to any Financing Party. 

  

	13.4	Upon the assignment of a Party’s obligations hereunder to any permitted assignee, and such permitted assignee’s assumption in writing of such obligations, such Party shall
be deemed released from and shall have no further rights, obligations, responsibilities or liabilities under this Agreement; provided, however, for the avoidance of doubt, that Seller’s right to assign contained in Clause 13.2 shall in no event
release Seller from any obligation under this Agreement.

credited against any payments otherwise due from Buyer to Seller.

director, member, partner, employee and agent thereof from all liens (whether statutory or otherwise and including mechanics’ or suppliers’ liens), claims and liability hereunder with respect to any Work performed or furnished in
connection with this Agreement, or for any act or omission of Buyer or of any Person relating to or affecting this Agreement, except claims for which Seller has delivered a notice of dispute to Buyer. For the avoidance of doubt, bank acceptance and
deposit of a wire transfer or of a lockbox payment does not constitute Seller acceptance for the purposes of this Article. 

  

	17.7	In accordance with Clause SC-16.1 above, Seller shall breakdown the Agreement Price into the following categories and shall issue the Buyer separate invoice for each:

  

	 	(i)	“incorporated materials qualifying for exemption as manufacturing equipment”, which is for the cost of Equipment (equal to the actual raw material or equipment cost
incurred by Seller without the addition of any on site labor, fees, profit or other costs) that is incorporated into the Project and qualifies for exemption as “manufacturing equipment” pursuant to Texas Tax Code § 151.318 or Texas
Comptroller’s Sales Tax Rule 34 Tex. Admin. Code § 3.300; 

  

	 	(ii)	“incorporated materials not qualifying for exemption as manufacturing equipment”, which is for the cost of Equipment (equal to the actual raw material or equipment cost
incurred by Seller without the addition of any on site labor, fees, profit or other costs) that is incorporated into the Project and does not qualify for exemption as “manufacturing equipment” pursuant to Texas Tax Code § 151.318 or
Texas Comptroller’s Sales Tax Rule 34 Tex. Admin. Code § 3.300; 

  

	 	(iii)	“equipment and materials transferred to Owner as tangible personal property”, which is for the cost of Equipment such as chemicals and lubricants and operating supplies
and spare parts that Seller transfers to Buyer as tangible personal property; 

  

	 	(iv)	“taxable services resold to Owner”; and

	17.8	Payment delays by Buyer: 

  

	 	(i)	In the event that Buyer fails to make payment of an amount properly invoiced by Seller and due to Seller under this Agreement in a case where Buyer has not disputed the payment of
such amount, and such failure to pay continues beyond the due date for payment, the Seller shall be entitled to payment of interest on such unpaid amount for the period of delay beyond the due date. The rate of interest shall be calculated at two
percent (2%) over the per annum rate of interest equal to the prime lending rate as may from time to time be published in the Wall Street Journal (Eastern edition) under “Money Rates”; provided the interest rate shall never
exceed the maximum lawful rate permitted by Applicable Laws. 

  

	 	(ii)	In the event that Buyer fails to make payment of an amount properly invoiced by Seller and due to Seller under this Agreement, and such failure to pay continues beyond forty five
(45) days after the due date for payment, the Seller shall, on forty five (45) days notice to Buyer given any time after the foregoing forty five (45) day period, be entitled to suspend performance with respect to the Equipment and
services for which such payment was due and claim an equitable extension of time (depending upon Seller’s then current production constraints) and reimbursement of the reasonable costs incurred by such suspension, save where failure to make
such payment arises on the grounds of a good faith dispute in which event such right to suspend shall arise only after (i) such dispute has been resolved in Seller’s favor by negotiation or dispute resolution as provided in Clause SC-35
(Dispute Resolution), (ii) such disputed amount has subsequently been invoiced pursuant to Clause SC-18.1 (Payment Schedule) and (iii) Buyer has thereafter failed to make payment of such disputed amount as provided in this Clause 17.8
(ii). (Price and Payment) 

  

	 	(iii)	If the Buyer has failed to make payment within ninety (90) Days from the Payment Due Date of invoice of any undisputed payment due, and properly invoiced, under the Agreement,
the Seller shall on sixty (60) Days notice given any time after the foregoing ninety (90) Days period to Buyer and the Financing Parties be entitled to terminate performance with respect to the Equipment and services for which such payment
was due save where failure to make such payment arises on the grounds of a good faith dispute in which event such right to terminate shall arise only after (i) such dispute has been resolved in Seller’s favor by negotiation or dispute
resolution as provided in Clause SC-35 (Dispute Resolution), (ii) such disputed amount has subsequently been invoiced pursuant to Clause SC-18.1 (Payment Schedule) and (iii) Buyer has thereafter failed to make payment of such disputed
amount as provided in this Clause 17.8(iii) (Price and Payment). In connection with any such termination, Buyer shall make the termination payment as set forth in Section 5, Clause SC-19 (Termination Payment Schedule) of this Agreement.

  

	 	(iv)	For the avoidance of doubt the above remedies available to Seller shall not apply in circumstances where the Buyer has exercised a right granted under this Agreement to withhold
payment of sum(s) otherwise due to Seller under this Agreement. 

  

	17.9	Buyer shall be entitled to set off any and all sums due to Buyer under this Agreement from any and all sums payable to Seller under this Agreement. In addition, Buyer shall be
entitled to set off any and all sums due to Buyer under this Agreement from any and all sums payable to Seller under any other SP Purchase Order.

Seller has failed to perform some or all of its obligations under one or more of the SP Purchase Orders, Buyer shall have the right to make a draw against the Performance Letter of Credit. Buyer shall give five (5) Days advance notice to Seller
prior to any draw against the Performance Letter of Credit. Buyer has a right to request that Seller extend the duration of the period of time that the Performance Letter of Credit remains at ten percent (10% ) of the Agreement Price of all eight
(8) of the SP Purchase Orders or the period of time that the Performance Letter of Credit remains at five (5%) of the Agreement Price of all eight (8) of the SP Purchase Orders, and Seller shall extend such periods (subject only to

	SC-20	RELEASE AGAINST LIENS AND CLAIMS 

  

	20.1	Seller shall not directly or indirectly create, incur, assume or suffer to be created by it or any Subcontractor, employee, laborer, materialman or other supplier of goods or
services to Seller any right of retention, mortgage, pledge, assessment, security interest, lease, advance claim, levy, claim, lien, charge or encumbrance on the Work, the Equipment, the Site, the Project or any part thereof or interest therein
(each a “Seller Lien”). Seller shall keep the Site, the Work, the Equipment, and all Subcontractor equipment and materials free of Seller Liens. Seller shall promptly pay or discharge, and discharge of record, any such Seller Lien or other
charges which, if unpaid, might be or become a Seller Lien. Seller shall immediately notify Buyer of the assertion of any Seller Lien. 

  

	20.2	If any Indemnified Party becomes aware of any Seller Lien, such Indemnified Party may so notify Seller in writing with a copy to Buyer, and Seller shall then: (a) satisfy and
obtain the release of such Seller Lien; or (b) provide to Buyer a bond in the amount of such lien. If Seller does not promptly, and in any event within seven (7) days after such notice, satisfy such Seller Lien or provide such a bond, then
Buyer shall have the right, at its option, after written notification to Seller, and subject to Applicable Law, to cause the release of, pay, or settle such Seller Lien, and Buyer at its sole option may: (x) draw on the Retention Bank Guarantee
in an amount equal to all costs and expenses incurred by Buyer in causing the release of, paying, or settling such Seller Lien, including administrative costs, attorneys’ fees, and other expenses, or (y) withhold from any payment otherwise
due to Seller hereunder an amount equal to all costs and expenses incurred by Buyer in causing the release of, paying, or settling such Seller Lien, including administrative costs, attorneys’ fees, and other expenses. 

 

	SC-21	INDEMNITY 

  

	21.1	SELLER AGREES TO DEFEND, INDEMNIFY, AND HOLD BUYER AND INDEMNIFIED PARTIES, HARMLESS FROM AND AGAINST ANY DAMAGES WHICH ARISE OR ARE ALLEGED TO ARISE OUT OF PERSONAL INJURY OR DEATH
OR LOSS OF OR DAMAGE TO THE TANGIBLE PROPERTY OF A THIRD PARTY AND WHICH ARISE BEFORE EXPIRATION OF SIXTY (60) MONTHS FOLLOWING FINAL COMPLETION TO THE EXTENT SUCH DAMAGES RESULT FROM THE NEGLIGENCE OR OTHERWISE TORTIOUS ACT OR OMISSION
(INCLUDING STRICT LIABILITY) OF SELLER OR ITS SUB-SUPPLIERS OR SUBCONTRACTORS IN CONNECTION WITH THIS AGREEMENT OR ANY PERSON EMPLOYED BY ANY OF THEM. FOR THE PURPOSES OF THIS CLAUSE SC-21.1, THIRD PARTY LIABILITY SHALL NOT INCLUDE DAMAGE TO
TANGIBLE PROPERTY FORMING PART OF THE FACILITY. 

  

	21.2	The Indemnified Parties shall, as a condition precedent to Seller’s obligations under this Clause SC-21, promptly notify Seller of any claim or suit and provide Seller a
reasonable opportunity to control the defense and settlement of any claim or suit tendered to Seller under this clause (an “Indemnified Claim”). If Seller assumes the defense of Indemnified Parties in accordance with the provisions of this
Clause SC-21, Seller shall keep Indemnified Parties consulted and reasonably informed of the claims, litigation and negotiations of the Indemnified Claim, and shall pay all legal expenses and reasonable direct costs incurred by Indemnified Parties
in connection with the Indemnified Claim. The Indemnified Parties shall be entitled to participate in the defense of any Indemnified Claim at their own expense, and shall provide Seller with all assistance reasonably requested by Seller at
Seller’s expense. Seller agrees that it shall not settle any Indemnified Claim without the prior consent of the Indemnified Parties, such consent not to be unreasonably withheld so long as such settlement completely discharges or releases the
Indemnified Claim against the Indemnified Parties and does not impose by way of consent decree, injunction or otherwise any restraint or limitations on the Indemnified Parties’ operations or upon the operation or other use of the Equipment or
the Facility.

	21.3	If Seller fails to assume the defense or to diligently defend any Indemnified Claim, then the Indemnified Party may, upon giving prior notice to Seller, contest (or with the prior
consent of Seller settle) such Indemnified Claim, and Seller shall be liable for paying the reasonable legal expenses and other direct costs incurred by Indemnified Parties in connection with the Indemnified Claim as such expenses and costs accrue.

  

	21.4	If the defendants in an action on an Indemnified Claim include both Seller and an Indemnified Party, and the Indemnified Party reasonably concludes that there may be legal defenses
available to it which are in conflict with those available to the Seller, and that such conflict materially prejudices the ability of the counsel selected by the Seller to represent both Parties, such Indemnified Party shall have the right to select
separate counsel reasonably acceptable to the Seller to participate in the defense of such action on its own behalf at Seller’s expense; provided, however, if Buyer is the Indemnified Party that believes that such a conflict of interest exists
(but only to the extent “Buyer” in this case is Bechtel Power Corporation or any Affiliate of Bechtel Power Corporation), then (a) Buyer may elect to use their own attorneys in such matter at Buyer’s expense, and (b) Seller
shall reimburse Buyer for Seller’s Proportional Share (as defined below) of Buyer’s reasonable legal expenses upon resolution of such claim or suit. 

  

	21.5	Seller’s obligation to hold Indemnified Parties harmless under this Clause SC-21 includes responsibility for paying Seller’s Proportional Share of the reasonable legal
expenses and other direct costs incurred by Indemnified Parties in connection with any Indemnified Claim. For the purposes of this Clause SC-21, Seller’s Proportional Share shall mean 100% of the Indemnified Parties’ reasonable legal
expenses and other direct costs, until (a) fault is apportioned among Seller and the Indemnified Parties by the court or other forum hearing the Indemnified Claim, or (b) if such court or other forum does not apportion fault, until fault
is apportioned among Seller and the Indemnified Parties pursuant to separate dispute resolution proceedings among such parties. If, following such apportionment, Seller has paid more than Seller’s Proportional Share, the Indemnified Party or
Parties benefiting from such payment shall reimburse Seller for such amounts in accordance with the apportionment of liability. Alternatively, if Seller has paid less than Seller’s Proportional Share, it shall reimburse the Indemnified Parties
for their additional costs and expenses in accordance with the apportionment of liability. 

  

	SC-22	NONDISCLOSURE 

  

	22.1	Except as required by Clause SC-22.3 (Nondisclosure) or Applicable Laws or applicable stock exchange rules and regulations, Seller and Buyer agree not to divulge to third parties
(other than its and its Affiliates, and their respective employees, directors, officers, members, accountants, attorneys, Financing Parties or authorized representatives, collectively, “Representatives”), unless such third party is subject
to written confidentiality commitments substantially similar to the requirements contained in this Clause SC-22 (Nondisclosure), without the prior written consent of the other, any Confidential Information, obtained from or through each other in
connection with the performance of this Agreement and Seller and Buyer agree to restrict the use of such Confidential Information solely to uses related to the Project. Seller further agrees that it will not, without the prior written consent of
Buyer and Owner, disclose to any third party any information developed by it or its Subcontractors in the performance of this Agreement and that such information will only be used for purposes related to the Project. If so requested by Buyer, Seller
further agrees to require its employees and its Subcontractors and their employees to execute an appropriate nondisclosure agreement prior to performing any Work under this Agreement. This non-disclosure obligation shall remain in full force and
effect for five (5) years from the end of the Warranty Period. Notwithstanding anything to the contrary in this Agreement, Buyer may divulge Confidential Information to Owner and its Affiliates and their respective employees, directors,
officers, managers, accountants, attorneys, Financing Parties and authorized representatives; provided that each Party shall be responsible for any breach of this Agreement by any of their respective Representatives and each Party agrees, at its
sole expense, to take all reasonable measures (including but not limited to court proceedings) to restrain its Representatives from

	    	prohibited or unauthorized disclosure or use of any Confidential Information. To the extent that Seller’s Confidential Information (other than general arrangement drawings with
respect to the Equipment) are marked confidential or proprietary, such Confidential Information shall be further restricted such that no disclosure shall be made to competitors of Seller without Seller’s consent, not to be unreasonably withheld
or delayed; provided, however, such general arrangement drawings may only be disclosed to competitors of Seller without Seller’s consent in the event that Seller is unable or unwilling to complete the Work, or any portion of the Work, related
to such drawings in accordance with this Agreement. 

  

	22.2	Seller shall, on request by Buyer or Owner, execute a separate confidentiality agreement with Owner under which Seller shall agree to keep the Proprietary Operating Information
confidential and Seller shall procure that its Subcontractors similarly execute confidentiality agreements with Owner under which they shall agree to keep the Proprietary Operating Information confidential. In addition, on request by Buyer, Seller
shall procure that its employees and the employees of its Subcontractors execute individual confidentiality acknowledgements under which they will agree to keep the Proprietary Operating Information confidential. 

  

	22.3	If the receiving Party is required pursuant to any court order, subpoena or in connection with any proceeding to disclose any Confidential Information, prior to making any such
disclosure under this Clause SC- 22, the receiving Party shall (i) provide the disclosing Party with timely advance written notice of the Confidential Information requested by such Governmental Agency and the receiving Party’s intent to so
disclose (ii) minimize the amount of confidential information to be provided consistent with the interests of the disclosing Party or Owner interests and the requirements of the Governmental Agency involved and (iii) at the request and
expense of the disclosing Party or Owner make commercially reasonable efforts (which shall include, to the extent possible, participation by the other Party in discussions with the Governmental Agency involved) to secure confidential treatment and
minimization of the confidential information to be provided. 

  

	SC-23	INDEMNIFICATION FOR VIOLATION OF LAWS 

  

	23.1	SELLER SHALL INDEMNIFY, DEFEND AND HOLD HARMLESS THE BUYER AND INDEMNIFIED PARTIES FROM AND AGAINST ANY AND ALL FINES AND PENALTIES IMPOSED BY ANY GOVERNMENTAL AGENCY INCLUDING
REASONABLE LEGAL FEES INCURRED IN CONNECTION THEREWITH FROM OR RELATED TO ANY FAILURE OF SELLER, OR ANYONE ACTING ON SELLER’S BEHALF, TO COMPLY WITH (I) ALL APPLICABLE LAWS INCLUDING PAYMENT TAXES AND DUTIES TO BE PAID BY SELLER AND (II)
APPLICABLE PERMITS TO THE EXTENT SUCH COMPLIANCE IS THE RESPONSIBILITY OF THE SELLER PROVIDED SUCH FAILURE IS NOT CAUSED BY THE FAULT OR NEGLIGENCE OF THE BUYER OR PARTY INDEMNIFIED OR HELD HARMLESS. 

  

	23.2	The Indemnified Parties shall, as a condition precedent to Seller’s obligations under Clause SC-23, promptly notify Seller of any claim or suit and provide Seller reasonable
opportunity to control the defense and settlement of any claim or suit tendered to Seller under this clause. If Seller has assumed the defense of Indemnified Parties in accordance with the provisions of this Clause SC-23, Seller shall keep
Indemnified Parties consulted and reasonably informed of the claims, litigation and negotiations, provided that Indemnified Parties shall be entitled at Indemnified Party’s expense to participate in such defense. Seller agrees that it shall not
settle any suit for which it is providing indemnity under this Agreement without the prior consent of the Indemnified Parties, such consent not to be unreasonably withheld so long as such settlement completely discharges or releases the
indemnifiable claims against the Indemnified Parties and does not impose by way of consent decree, injunction or otherwise any restraint or limitations on the Indemnified Party’s operations or upon the operation or other use of the Equipment or
the subject generating facility. In connection with this indemnity Buyer or Owner shall render such reasonable assistance in the defense thereof as Seller may require. If any claim, suit, action, proceeding or

	    	investigation arises as to which the indemnity provided for under this Clause SC-23 hereof may apply and Seller, fails to assume the defense of, or to diligently defend, such claim,
action, proceeding or investigation, then the Buyer or Indemnified party may, upon giving prior notice thereof to the Seller, at the expense of Seller (to the extent Seller is responsible pursuant to Clause SC-23.1), contest (or, with the prior
written consent of Seller, settle) such claim. 

  

	SC-24	INDEMNIFICATION FOR HAZARDOUS MATERIAL 

  

	24.1	SELLER SHALL INDEMNIFY, DEFEND AND HOLD HARMLESS THE BUYER AND INDEMNIFIED PARTIES FROM AND AGAINST ANY AND ALL LIABILITIES, INCLUDING REASONABLE LEGAL FEES INCURRED IN CONNECTION
THEREWITH, TO THE EXTENT ARISING OUT OF OR IN CONNECTION WITH ANY HAZARDOUS MATERIAL BROUGHT ONTO THE PROJECT JOBSITE BY SELLER, UNLESS RESULTING FROM IMPROPER USE, HANDLING OR MAINTENANCE BY OWNER OR ANY OTHER PARTY FOR WHOM SELLER IS NOT
RESPONSIBLE AFTER THE EFFECTIVE DATE OF THIS AGREEMENT. BUYER SHALL, INDEMNIFY, DEFEND AND SAVE HARMLESS SELLER FROM AND AGAINST ANY AND ALL LIABILITIES, CLAIMS, DAMAGES, LOSSES OR EXPENSES FOR INJURY TO OR DEATH OF PERSONS AND FOR LOSS OF OR DAMAGE
TO THE PROPERTY OF THIRD PARTIES TO THE EXTENT ARISING OUT OF OR RESULTING FROM BUYER’S PERFORMANCE OR FAILURE TO PERFORM ITS OBLIGATIONS WITH RESPECT TO ANY HAZARDOUS MATERIAL BROUGHT ONTO THE JOBSITE BY BUYER. Buyer shall cause Owner to

reasonable opportunity to control the defense and settlement of any claim or suit tendered to Seller under this clause. If Seller has assumed the defense of Indemnified Parties in accordance with the provisions of this Clause SC-24.2, Seller shall
keep Indemnified Parties consulted and reasonably informed of the claims, litigation and negotiations, provided that Indemnified Parties shall be entitled at Indemnified Parties’ expense to participate in such defense. Seller agrees that it
shall not settle any suit for which it is providing indemnity under this Agreement without the prior consent of the Indemnified Parties, such consent not to be unreasonably withheld so long as such settlement completely discharges or releases the
indemnifiable claims against the Indemnified Parties and does not impose by way of consent decree, injunction or otherwise any restraint or limitations on the Indemnified Parties’ operations or upon the operation or other use of the Equipment
or the subject generating facility. In connection with this indemnity Buyer or Owner shall render such reasonable assistance in the defense thereof as Seller may require. If any claim, suit, action, proceeding or investigation arises as to which the
indemnity provided for under this Clause SC-24 hereof may apply and Seller, fails to assume the defense of, or to diligently defend, such claim, action, proceeding or investigation, then the Buyer or Indemnified party may, upon giving prior notice
thereof to the Seller, at the expense of Seller (to the extent Seller is responsible pursuant to Clause SC-24.1), contest (or, with the prior written consent of Seller, settle) such claim.

consents may, among other things, include provisions whereby Seller agrees to: (i) provide such Financing Parties reasonable notice of and opportunity to cure any Buyer’s defaults hereunder; (ii) allow such Financing Parties (as
security for Owner’s financing) to be assigned all of Buyer’s rights hereunder and in such assets in the event of a default of Buyer; provided, however, that Buyer and/or Owner shall keep Seller currently informed of such assignment or
reassignment; and (iii) provide for other customary investor or lender protection provisions that are not in violation of Applicable Law, and (z) deliver customary legal opinions of counsel to Owner. Seller shall respond promptly to
reasonable requests for existing information regarding the qualifications, experience, past performance and financial condition of Seller and other matters pertaining to Seller’s obligations hereunder. Notwithstanding the foregoing, under no
circumstances shall Seller be obligated to enter into any amendment and modification of this Agreement, or any other agreement with Buyer or the Financing Parties, that materially (i) reduces Seller’s rights as set forth in this Agreement;
(ii) increases Seller’s cost or risk to perform the Work, or (iii) reallocates to Seller any risks or obligations that are allocated to Buyer under this Agreement. 

  

	45.2	Seller shall provide such data, reports, certifications and other documents, up to a maximum of ten (10) copies each, or assistance related to the Work or this Agreement as may
be reasonably requested by the Financing Entities with respect to the financing of the Project; provided, however, that the provision of this information shall not in any manner modify Seller’s rights or obligations under any
other provision of this Agreement. 

  

	45.3	Seller shall to the extent reasonably requested by Owner or Buyer, assist Owner and Buyer in dealing with Governmental Authorities and Financing Entities in any and all matters
relating to the Work (including any interconnection facilities). 

  

	45.4	Seller will each use its reasonable efforts to implement the provisions of this Agreement, and for such purpose, at the reasonable request of the Owner or Buyer, will, without
further consideration, promptly execute and deliver or cause to be executed and delivered such assistance, or assignments, consents or other instruments in addition to those required by this Agreement, in form and substance satisfactory to the
Parties, that may reasonably deem necessary or desirable to implement any provision of this Agreement. 

  

	SC-46	BUYER’S APPROVAL OF SELLER’S MAJOR SUBCONTRACTORS 

  

	46.1	To the extent Seller purchases equipment identified in Section 5, Appendix 10 hereto, List of Acceptable Equipment Suppliers, it will purchase such equipment from
Subcontractors included on the list or obtain Buyer’s written approval prior to purchase. 

 At the time of execution of
the Agreement, Buyer has approved (i) the manufacturing facilities of Seller’s affiliated companies; and (ii) Seller’s “Vendor List” Section 5, Appendix 10 identifying Seller’s major equipment
sub-supplier’s.

	By Seller:                     	 		 	By Buyer:                     

 Buyer shall approve any deviation from Seller’s “Vendor List” with respect to the supply
of rotors, stators and castings. The intent of such approval is not to restrict Seller’s ability to use global sourcing but to ensure Buyer that Seller is using reliable, proven and qualified suppliers. This clause applies to the major
components of rotors, stators and casings only and shall not restrict the Seller from procuring other components or materials from any Seller approved sub-supplier. 
  

	46.2	Seller shall ensure that each Subcontractor is licensed or qualified to do business and is in good standing under the laws of the jurisdiction where the Work is to be performed.

  

	46.3	All of the contracts with first tier Subcontractors shall conform to the requirements of this Agreement, insofar as applicable. All Work performed for Seller by a Subcontractor
shall be pursuant to an appropriate written agreement between Seller and Subcontractor which shall contain provisions that: 

  

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

  

	 	(b)	Seller shall require that the Work to be performed under the Subcontract shall be in accordance with the applicable requirements of this Agreement; 

  

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

  

	 	(d)	Seller shall require each Subcontractor to notify Buyer and Owner in the event such Subcontractor intends to discontinue supplying any functional spare parts at any time within five
(5) years after completion of such Subcontractor’s work and permit Owner to order any quantity of any of such parts at the prices therefor prevailing prior to such discontinuance of supply; 

  

	 	(e)	Seller shall endeavor to require each Subcontractor to enter into a new contract directly with Owner on the same terms and conditions as such subcontract in the event that any
trustee in bankruptcy for Seller rejects the subcontract, or Subcontractor terminates such subcontract as a result of the bankruptcy of Seller, upon notice to Subcontractor; and where requested by such Subcontractor, presentation of reasonable
financial assurances but otherwise not subject to Subcontractor’s consent; 

  

	 	(f)	Seller shall allow assignment, including any performance assurance provided by such Subcontractor, of such agreement to Buyer or Owner, to another contractor that replaces the
Seller as designated by Owner, or at Owner’s request, to the Financing Parties, if any, upon the occurrence of an event of default under the Prime Contract or the termination or expiration of this Agreement, upon notice to Subcontractor, and
where requested by such Subcontractor, presentation of reasonable financial assurances but otherwise not subject to Subcontractor’s consent; 

  

	 	(g)	Seller shall require each Subcontractor to remove from the Site any employee or independent contractor of such Subcontractor used in the Work or in such Subcontractor’s
warranty obligations within one (1) Business Day after receiving notice from Buyer that Owner requires removal of such employee or independent contractor; 

  

	 	(h)	Seller shall require each Subcontractor to abide by Seller’s obligations hereunder and to otherwise hold in strict confidence all of Buyer’s and Owner’s Confidential
Information;

	 	(i)	Seller shall require each Subcontractor to deliver to Buyer and Owner any “stop-work” notice or termination notice delivered to Seller pursuant to Applicable Law; and

  

	 	(j)	Seller shall use commercially reasonable efforts to procure that all subcontracts signed with a Major Subcontractor or Other Critical Subcontractor that contain provisions, which
Seller may not waive, release, modify or impair, giving Seller an unrestricted right, without the consent of the subcontractor in question, to assign the relevant subcontract and any or all benefits, interests, rights and causes of action arising
under it to Buyer and/or its designees (and such assignment right will be assigned as part of such assignment). From time to time, on Buyer’s request, Seller shall furnish Buyer with written demonstration of its compliance with this Clause
SC-46.3. 

  

	46.4	In addition to the above provisions, Seller shall: 

  

	 	(a)	notify Buyer and Owner in the event it intends to discontinue supplying any functional spare parts at any time within five (5) years after completion of its Work and permit
Owner to order any quantity of any of such parts at the prices therefor prevailing prior to such discontinuance of supply; 

  

	 	(b)	remove from the Site any of its employees or independent contractors used in the Work or in its warranty obligations within one (1) Business Day after receiving notice from
Buyer that Owner requires removal of such employee or independent contractor; provided that any such removal notice be supported by reasonable business reasons therefor. 

  

	SC-47	TRAINING 

 To the extent specified herein, Seller
shall develop and implement a program to instruct and train personnel made available by Owner. Seller grants Buyer and Owner the right to record all training sessions and replay such recordings for retraining or training of others. 
  

	SC-48	APPENDICES 

 The Appendices listed herein in the
Table of Contents and attached hereto are incorporated into and are a part of this Agreement. 
  

	SC-49	STANDARD PLANT PROGRAM 

  

	49.1	It is recognized that this Agreement is being signed in conjunction with a number of other purchase orders signed with Seller (or to be signed with Seller in the future) in
connection with Owner’s Standard Plant Program, under which purchase orders Seller will supply (or has supplied) equipment which is identical in design and in all material respects to the Equipment; provided the Parties acknowledge that
modifications to the Equipment may be required in order to satisfy this Clause SC-49. 

  

	49.2	It is further recognized that the overall objectives of the Owner’s Standard Plant Program (“SP Objectives”) are as set out below: 

  

	 	(i)	standardization of equipment supply across all SP Projects; 

  

	 	(ii)	maximization of the benefits of bulk supply and global sourcing; 

  

	 	(iii)	standardization of operation and maintenance practices across all SP Projects; and

	By Seller:                     	 		 	By Buyer:                     

	 	(iv)	maximum enhancement of the schedule for engineering, procurement, construction, commissioning, start-up, testing and completion of each SP Project. 

  

	49.3	In the course of performance of the Work under this Agreement, Seller shall use commercially reasonable efforts to assist Buyer in the realization of the SP Objectives and shall
plan and execute its Work so as to ensure the realization of the SP Objectives to the maximum practical extent. 

  

	49.4	Without limiting Clause 49.3 above; 

  

	 	(a)	Seller shall select manufacturing and assembly locations for the Equipment which are consistent with the SP Objectives; 

  

	 	(b)	All similar components provided by Seller under each SP Purchase Order shall be identical in all material respects so as to ensure full interchangeability and availability of common
spares across all SP Projects; and 

  

	 	(c)	Promptly on Buyer’s request, Seller shall establish a combined spare parts program across all SP Projects, which shall be reasonably acceptable to Buyer and which shall ensure
ready access to spare parts as needed for each SP Project. 

  

	49.5	Seller shall provide prompt notice to Buyer as to any enhancements Seller is proposing to make to the standard production components for its equipment (together with supporting
information as reasonably requested by Buyer) and Seller shall, if requested in writing by Buyer, modify and improve the equipment under each SP Purchase Order in order to incorporate such enhancements, provided that any such enhancements shall be
made at no additional cost to Buyer and with no adverse impact to the schedule under any SP Purchase Order. 

  

	49.6	Seller shall comply with any written direction from Buyer requiring that equipment (or components therefor) planned to be supplied to one SP Project shall be diverted to a different
SP Project. Any such written direction by Buyer shall be treated as a directed change under the SP Purchase Order for the SP Project from which the equipment (or component) was diverted. 

  

	49.7	From the Effective Date through the end of the Warranty Period, should Buyer identify any defect or other deficiency in the equipment provided under any SP Purchase Order (or under
multiple SP Purchase Orders) which gives Buyer reasonable cause for concern as to the same or similar defects occurring with respect to other SP Purchase Orders, Seller shall submit to Buyer, for Buyer’s approval, a plan for correcting and
eliminating such defects. Upon Buyer’s approval of such plan, Seller shall promptly implement such plan and shall provide regular written reports to Buyer as to the implementation of such plan. 

  

	49.8	Seller shall negotiate in good faith with Buyer a long term parts and service agreement to be signed with Buyer or Owner with respect to the Equipment. 

  

	SC-50	DRAWBACK RIGHTS 

 This Agreement includes all
related US customs duty and import drawback rights if any (including rights developed by substitution and rights which may be acquired from Seller’s suppliers) which Seller can transfer to Buyer. Seller agrees to provide Buyer timely notice of
the existence of any such rights and upon request to supply such documents as required to obtain drawback.

	2.0	GENERAL 

  

	 	A.	Seller’s obligations respecting the performance of its Equipment include: 

  

	 	a.	The obligations to meet the Equipment Performance Guarantees as set forth in Clause 3.0 of this Appendix 4 or to pay Performance Liquidated Damages for acceptable deviations, as
stated in that Clause. 

  

					
		 	Page 3 of 20	 	
	By Seller:                     	 		 	By Buyer:                     

	 	b.	The obligations to meet the guarantee respecting Equipment Equivalent Availability Factor (EEAF) as set forth in Clause 4.0 of this Appendix 4 or to pay Reliability Liquidated
Damages for acceptable deviations as stated in that Clause. 

  

	 	c.	The obligations to successfully complete the Functional Tests, as required under Clause 5.0 of this Appendix 4. 

  

	 	d.	The obligations to meet any other performance and/or testing requirements stated in the Technical Specifications. 

  

	 	B.	Successful demonstration of each Facility Performance Guarantee and the Reliability Guarantee, requires both that (a) the Facility demonstrates that it meets the guaranteed
performance level for the particular guaranteed item under the conditions specified, and (b) Buyer declares and Owner accepts that the particular Performance Test or Reliability Test in which such demonstration occurs is a Completed Performance
Test for purposes of Substantial Completion or Final Completion (as applicable) under the Prime Contract. 

 IT IS EXPRESSLY
UNDERSTOOD AND AGREED THAT SELLER SHALL NOT BE CONSIDERED TO HAVE MET ITS OBLIGATIONS UNDER THIS APPENDIX 4 UNLESS THE FACILITY AS A WHOLE HAS MET THE CRITERIA FOR FINAL COMPLETION, EVEN IF SELLER’S EQUIPMENT PERFORMS SATISFACTORILY AND BUYER
MUST REPERFORM THE APPLICABLE PERFORMANCE TEST FOR REASONS OUTSIDE SELLER’S CONTROL. 
  

	 	C.	During any Performance Test, the Facility shall comply with all Applicable Laws and permits in order for the Performance Test to be considered valid. 

  

	 	D.	Liquidated damages shall be payable under this Appendix 4 based on the corrected results of the applicable Completed Performance Test and in accordance with other provisions
contained in this Agreement.. Seller shall pay any liquidated damages due under this Appendix within five (5) days of receipt of invoice. 

  

	 	E.	The Completed Performance Tests (including the Reliability Test) selected and designated by Buyer for Substantial Completion or Final Completion or otherwise for the payment of
Performance LDs (as applicable) will be the tests selected by Buyer and accepted by Owner. 

  

	 	F.	The Prime Contract will include an initial cure period beginning on the Substantial Completion Date and ending one hundred eighty (180) days later (“Cure Period”) for
the achievement of the Facility Performance Guarantees. During the Cure Period, Seller shall exercise all reasonable efforts to make all refinements, repairs, and modifications that may be necessary or desirable to enhance Equipment performance up
to compliance with a 100% level of achievement of all Equipment Performance Guarantees. If Seller achieves a 100% level of achievement of all Equipment Performance Guarantees, but the Facility has not achieved 100% of the Facility Performance
Guarantees, Seller agrees to assume the costs of one additional test (the “Post Guarantee Test”) in an effort to achieve 100% of the Facility Performance Guarantees. For any test occurring after the Post Guarantee Test, the Parties agree
that Seller’s reasonable additional costs incurred in connection with such additional testing will be borne by Buyer so long as all Equipment Performance Guarantees have been met and so long as all Equipment Performance Guarantees continue to
be met during the Cure Period; provided, any costs incurred by

	By Seller:                     	 		 	By Buyer:                     

 Seller relating to witnessing of any testing shall be borne by Seller. In the event that the Facility
Performance Guarantees have not been achieved on or prior to the expiry of the Cure Period, Buyer may determine in its sole discretion either (a) to submit to Owner a remedial plan for achievement of the Facility Performance Guarantees; or
(b) to decline to submit such a remedial plan. 
  

	 	(i)	In the event that Buyer declines to submit a remedial plan then Performance LDs shall be payable by Seller under this Appendix 4 based on the results of the Completed Performance
Test as determined by Buyer and Owner. 

  

	 	(ii)	In the event that Buyer submits a remedial plan (including proposal for extension to the Cure Period (“Cure Period Extension”)) but Owner does not approve such remedial
plan, then Performance LDs shall be payable by Seller under this Appendix 4 based on the results of the Completed Performance Test as determined by Buyer and Owner; but, notwithstanding payment of such Performance LDs, Seller shall, if required by
Buyer, continue to exercise all reasonable efforts during the Cure Period Extension to make all refinements, repairs, and modifications that may be necessary to enhance Equipment performance up to compliance with a 100% level of achievement of all
Equipment Performance Guarantees. 

  

	 	(iii)	In the event that there is a Cure Period Extension then Seller’s liability for Performance LDs with respect to each Equipment Performance Guarantee shall be reassessed based on
the results of the Completed Performance Test conducted during the Cure Period Extension, as determined by Buyer and Owner, and 

  

	 	(x)	to the extent that the Performance LDs as reassessed are less than the amount of Performance LDs previously paid by Seller pursuant to paragraph (ii) above, then the amount of
the difference shall be refunded to Seller; and 

  

	 	(y)	to the extent that the Performance LDs as reassessed exceed the amount of Performance LDs previously paid by Seller pursuant to paragraph (ii) above, then the amount of the
difference shall be paid by Seller, in addition to the Performance LDs previously paid by Seller. 

  

	 	(iv)	In the event Buyer submits a remedial plan (including proposal for extension to the Cure Period (“Cure Period Extension”)) and Owner approves such remedial plan, then
Seller shall, if required by Buyer, continue to exercise all reasonable efforts during the Cure Period Extension to make all refinements, repairs, and modifications that may be necessary or to enhance Equipment performance up to compliance with a
100% level of achievement of all Equipment Performance Guarantees. 

  

	 	G.	During the Cure Period and any Cure Period Extension, Buyer will allow Seller access to Seller’s Equipment for tuning to the extent such access is provided by Owner under an
approved remedial plan. 

  

	 	H.	Except as provided in Section F above, upon payment of Performance Liquidated Damages under this Appendix 4, no further repairs and modifications are required to improve performance
with regard to the Equipment Performance Guarantees for which the liquidated damages are paid. This provision shall not be construed to limit Seller’s warranty obligations pursuant to Special Conditions Clause SC-6, entitled
“Warranties.” In the event that the Facility has achieved Substantial Completion but Seller has not achieved all of the Equipment Performance Guarantees, Seller shall be obliged at request

 of Buyer, to modify, repair, adjust and re-test the Equipment in order to demonstrate achievement of the
Equipment Performance Guarantees. In the event that by the earlier of expiry of the Cure Period (as may be extended) and the Guaranteed Final Completion Date Seller has failed to achieve any or all of the Equipment Performance Guarantees Seller
shall be liable to pay Performance Liquidated Damages to Buyer as determined and directed by Buyer in respect of those Equipment Performance Guarantees which Seller has failed to achieve. 
  

	 	I.	EQUIPMENT PERFORMANCE LIQUIDATED DAMAGES PAYABLE BY SELLER SHALL BE ASSESSED IN ACCORDANCE WITH SECTION 3 BELOW, REGARDLESS OF WHETHER LIQUIDATED DAMAGES FOR PERFORMANCE SHORTFALL
ARE DUE FROM BUYER TO OWNER UNDER THE PRIME CONTRACT. 

  

	 	J.	Further understandings in respect of the Reliability LDs provided in Article 4.0 are set out in paragraphs (a) through (e) below: 

  

	 	a.	Buyer (acting reasonably, fairly and equitably) shall determine responsibility for shortfalls in the guaranteed Facility EAF as between Buyer, Seller and Buyer’s other
contractors or suppliers based upon the calculated EEAF of the Seller’s Equipment. If and to the extent that such shortfalls are in Buyer’s opinion (acting reasonably, fairly and equitably) the responsibility of Seller, Buyer (acting
reasonably, fairly and equitably) shall assess and apportion responsibility to the Seller. 

  

	 	b.	Buyer shall give written notice to Seller of any determination of responsibility under this clause, and of any resulting assessment and obligation to pay liquidated damages to
Buyer. Buyer will promptly provide Seller with full details of all relevant calculations and with copies of all relevant correspondence and other documents upon which such determination, assessment and attribution were based.

  

	 	c.	With respect to Reliability LDs, if Owner does not recover or seek to recover from Buyer liquidated damages for failure to achieve the Guaranteed EAF under the Prime Contract, Buyer
shall not be entitled to recover Reliability LDs under this Agreement for Seller’s failure to meet its guaranteed EEAF. 

  

	 	d.	In no event shall the Reliability LDs recoverable from Seller be in excess of the amount of the liquidated damages recovered or sought from Buyer by Owner for failure to achieve the
Guaranteed EAF under the Prime Contract. 

  

	 	e.	Buyer has the sole right to determine and declare which tests or series of tests will be used to demonstrate the overall Facility performance. 

  

	 	K.	Performance Tests shall be run in accordance with this Appendix 4. Buyer shall give Seller reasonable notice of the date or dates on which the Performance Tests shall begin.

  

	 	L.	The Parties agree that it would be extremely difficult and impracticable under the presently known and anticipated facts and circumstances to ascertain and affix the actual damages
that Buyer would incur should the Facility meet the Minimum Facility Performance Criteria but fail, due to reasons attributable to Seller’s Equipment, to meet the Facility Performance Guarantees and/or Reliability Guarantee. Accordingly, the
Parties agree that the amounts specified herein for Performance Liquidated Damages and Reliability Liquidated Damages are not intended as penalties but rather as reasonable projections of damages that Buyer might incur for failure to meet the
Facility Performance Guarantees and Reliability Guarantee, respectively.

	 	B.	Completion 

 To achieve Substantial Completion with
respect to performance guarantees, the Facility must demonstrate the Minimum Facility Performance Criteria. 
 To achieve Final Completion
with respect to performance guarantees, the Facility must: 
 a) Either 
  

	 	i)	meet 100% of all of the Facility Performance Guarantees during the Performance Guarantee Tests while meeting the continuously monitored Guaranteed Air Emissions (as measured by the
CEMS); or 

  

	 	ii)	meet the Minimum Facility Performance Criteria during the Performance Guarantee Tests while meeting the continuously monitored Guaranteed Air Emissions (as measured by the CEMS) and
the applicable performance liquidated damages must be paid under the Prime Contract; and 

 b) successfully pass all of the
Functional Tests; and 
 c) Either 
  

	 	i)	achieve the Guaranteed Equivalent Availability Factor of ***% or greater, calculated in accordance with this Section 5, Appendix 4, Section 4.0 D during the Reliability
Test while meeting the continuously monitored Guaranteed Air Emissions (as measured by the CEMS); or 

  

	 	ii)	the applicable liquidated damages must be paid under the Prime Contract for failure to meet the guaranteed EAF during the Reliability Test while meeting the continuously monitored
Guaranteed Air Emissions (as measured by the CEMS); and 

 d) meet all of the Guaranteed Air Emissions, (continuous and
non-continuous), per the applicable EPA test methods. 
 The continuously monitored emissions consist of NOx, CO, SO2, Opacity, Mercury, and
Ammonia (if applicable). The Performance Guarantee Tests are more particularly described in Clause 6.0 below and will be conducted in accordance with the provisions of Clause 7.0 below.

	 	C.	Performance Liquidated Damages: 

 If in the
Completed Performance Test Seller’s Equipment fails to meet one of the Equipment Performance Guarantees set forth in Table 3.1, Seller shall pay as liquidated damages, and not as a penalty, an amount calculated at the rate shown in Table 3.1
for any deficiencies in meeting such Equipment Performance Guarantee.

 Unless specifically identified in Table 3.1 above as being subject to payment of liquidated
damages, all of the Seller’s Equipment Performance Guarantees listed in Material Requisition MRA-MKAA-00001, Appendix A shall be “Make Right” guarantees 
 Seller’s right to liquidate a failure to meet the Equipment Performance Guarantees identified in Table 3.1 above is contingent upon Seller achieving the Minimum Performance Criteria and upon that failure not
limiting the ability of the Facility to operate during any normal mode of operation. 
 The Equipment must meet each Equipment Performance
Guarantee, unless specifically stated otherwise. Excess performance in one Equipment Performance Guarantee shall not be allowed to offset shortfalls in performance of another Equipment Performance Guarantee. 
 With respect to those Equipment Performance Guarantees for which Performance Liquidated Damages are provided, the payment by Seller to Buyer of such
Performance Liquidated Damages in accordance with this Appendix 4 shall be Buyer’s sole and exclusive remedy in full and final satisfaction of Seller’s liability for performance shortfall, subject to the provisions of Clause 6.0, Paragraph
C of this Appendix 4 imposing on Seller costs of any retesting to the extent Performance Tests fail for reasons attributable to Seller.

	4.0	RELIABILITY GUARANTEE, RELIABILITY TEST AND RELIABILITY LIQUIDATED DAMAGES 

  

	 	A.	Reliability Guarantee: Seller guarantees that the EEAF, as measured during the Completed Reliability Test (and calculated in accordance with paragraph (D) below), will
not be less than ***%. 

  

	 	B.	Reliability Test: The Reliability Test consists of a 720-hour period of operation of the Facility, will be conducted in accordance with the procedures and protocols described
in Clause 7.0 below, and is a requirement for achieving Final Completion. 

 Seller shall participate with Buyer in a
Reliability Test to demonstrate to Owner that the Facility can achieve the Guaranteed Equivalent Availability Factor during the 720 hour Reliability Test period. 
 The period of testing for the Reliability Test shall commence whenever the Facility is ready after the startup of the Facility and continue until the Facility has achieved the guaranteed Equivalent Availability Factor
or better over a period of 720 hours, but not beyond the Guaranteed Final Completion Date. Buyer may at any time look back over the test data and designate the time period to be declared as the Reliability Test. Full outage due to Force Majeure
events or interruptions because the power purchaser cannot or will not accept power, and the related time required to shut down and restart for these outages, will not be counted as test hours and will extend the 720 hour test period. 
  

	 	a.	The Equipment Equivalent Availability Factor (EEAF) and the Facility Equivalent Availability Factor (EAF) shall be logged from the date of commencement of the Reliability Test.

  

	 	b.	Buyer will make all reasonable efforts to allow Seller access to the Equipment in order to minimize repair time. 

  

	 	c.	Buyer will advise Seller when any event occurs which affects the EEAF. Relevant logs and other plant operating records shall be made available to Seller’s representatives at
reasonable times and places upon request to the extent they have been made available by Owner to Buyer. 

  

	 	d.	Seller may have personnel present to monitor operation until the guarantee period has been completed. 

  

	 	e.	Buyer will determine the EAF using the formula as described in Clause 4.0 below.

	 	C.	Reliability Liquidated Damages: If in the Completed Reliability Test, the EEAF is less than the Reliability Guarantee value (EEAF) listed above, and if due to reasons
attributable to or within the control of Seller, Seller shall pay as liquidated damages an amount calculated at the rate shown below. If the EEAF is less than the Reliability Guarantee for reasons that are not solely attributable to Seller, Seller
shall pay an amount equal to the proportionate share of Seller’s responsibility. The payment by the Seller to the Buyer of Reliability LDs in accordance with this Article 4.0 shall be the Buyer’s sole and exclusive remedy in full and final
satisfaction of the Seller’s liability for failure to achieve the Reliability Guarantee. 

  

	 	D.	Notwithstanding the above, if the Facility fails to achieve the EAF identified in Section 3.0 B(c)(i) by the Guaranteed Final Completion Date, and to the extent the shortfall
is attributed to the Equipment, then the Seller shall be liable to pay to Buyer liquidated damages (Reliability Liquidated Damages), calculated in accordance with this Section 4, for any shortfall attributable to Seller as determined by the
difference in calculated EEAF from Seller’s guaranteed EEAF identified in Section 4.0 A. If Seller’s Equipment meets the EEAF in the time period selected by Buyer and identified to Owner, regardless of the Facility performance, Seller
shall not be liable for Reliability Liquidated Damages. 

  

	 	E.	If under this Section 4.0, the Facility achieves its EAF identified in Section 3.0 B(c)(i) then Seller shall be deemed to have satisfied its EEAF regardless of the actual
EEAF calculated in a Reliability Test.

 If the Facility failed to meet the Guaranteed Net Electrical Output, respectively, during the
Completed Net Electrical Output Test, the EAF and EEAF will be calculated based upon the “bought down” capacity of the Facility (i.e., after payment of the applicable Performance Liquidated Damages) for purposes of this Clause. 

For purposes of this Clause the EEAF shall be rounded to the nearest one hundredth of a percentage point.

	 	F.	To determine the EAF, an availability factor (AF) will be calculated for each dispatch level requested by the Owner during the designated test period. The sum of the individual AFs,
as calculated at each dispatch level, will be averaged on a time-weighted basis to determine the equivalent availability over the total test period. EAF is defined as follows: 

 EAF = {[(AF1 x
DP1) + (AF2 x DP2) + ... + (AFn x DPn)] ÷ TP} x
100% 
 Where: 
  

	 	AF    =	Availability factor calculated at each individual dispatch level and dispatch period as follows: 

  

	 	AF    =	(NKWHO) ÷ (DL x DP) 

  

	 	    	If the dispatch level for any dispatch period is zero, then the corresponding AF for that dispatch period is 1, provided the Facility is available. 

  

	 	NKWHO	= Net energy output calculated as the sum of kilowatt-hours generated by the Facility over each dispatch period, as measured at the high voltage side of the main transformer using
the Facility’s metering devices and as adjusted for the Facility guaranteed conditions. 

  

	 	DL    =	The net electrical dispatch level, in kilowatts, assigned by the dispatch authority. The dispatch level shall not be greater than the guaranteed Net Electrical Output of the
Facility. The dispatch level shall be constant over the dispatch period to which it applies. During periods of ramping the Facility load up or down to meet a dispatched load, the dispatch level will be considered the lower of the two dispatch loads
assigned by the dispatch authority. The DL cannot exceed the lesser of (1) the NEO or (2) the Net Electrical Capacity test results selected by Buyer to demonstrate the Net Electrical Output guarantee to Owner. 

  

	 	DP    =	The period associated with each individual dispatch level, measured in hours. The sum of the dispatch periods shall equal the total test period duration. 

 

	 	n       =	Total number of DPs in the test period 

  

	 	TP    =	Total test duration, in hours 

  

	 	G.	EEAF Calculation: 

 The EEAF will be determined as noted
below.

	By Seller:                     	 		 	By Buyer:                     

 EEAF = [AH-(EUDH+EPDH)]/PH * 100% 
 And: 
  

	 	AH	    = PH – (FOH + MOH + POH) 

  

	 	EUDH	    = Unplanned Derated Hours x Size of Reduction / MDC 

  

	 	EPDH	    = Planned Derated Hours x Size of Reduction / MDC 

 Where: 
  

					
	AH	  	=	  	Available Hours (Period Hours (PH) less Planned Outage Hours (POH), Forced Outage Hours (FOH), and Maintenance Outage Hours (MOH)) required by Seller to make repairs or adjustments to the
Equipment for the purposes of meeting Equipment Performance Guarantees or meet the guaranteed EEAF identified in Section 4.0 A
			
	PH	  	=	  	Period Hours = 720 Hours declared by Buyer to demonstrate the EAF. Periods of unavailability during the PH due to reasons not attributable to Seller’s Equipment shall be counted as
Available Hours when calculating the Seller’s EEAF.
			
	FOH	  	=	  	Forced Outage Hours attributable to Seller’s Equipment
			
	MOH	  	=	  	Maintenance Outage Hours attributable to Seller’s Equipment
			
	POH	  	=	  	Planed Outage Hours attributable to Seller’s Equipment
			
	EUDH	  	=	  	Equivalent Unplanned Derated Hours attributable to Seller’s Equipment
			
	EPDH	  	=	  	Equivalent Planned Derated Hours attributable to Seller’s Equipment
			
	MDC	  	=	  	Maximum Dependable Capacity = DL (as defined in the EAF equation)

 In determining the EUDH and EPDH, the size of the reduction shall be determined based upon the
shortfall in kilowatt-hours in the net electrical output from the MDC during the period of derated operation attributable to Seller’s Equipment. 
 Buyer shall “look back” over the data collected since the declared start of the Reliability Run and declare a 720 period to use as the basis of demonstrating the EAF and the Seller’s EEAF.

 When the Facility is required for dispatch and a fault occurs resulting in a total loss of generation,
the period of the forced outage shall begin when the Facility has been taken out of service such that it is no longer capable of being dispatched as evidenced by the operation records and shall end when the Facility has been, or was made ready to
have been, returned to the required operating condition (in accordance with the start-up and ramp-up rates included in station manuals) following completion of the repairs . 
 A Planned Outage shall begin when the Facility has been taken out of service such that it is no longer capable of being dispatched by Owners as evidenced
by the operation records and shall end when the Facility has been returned to the required operating condition (in accordance with the start-up and ramp-up rates included in the station manuals). 
 Buyer shall have the right (and Seller shall have the right to participate in such inspection to the extent Buyer has such right of inspection) at all
reasonable times during the Reliability Test to inspect the Facility, Equipment and all ancillary parts thereof. If as a result of such an inspection, Buyer becomes aware of (or Seller notifies Buyer of) abnormal operating conditions or an impending
failure, and if Owner and Buyer agree (each acting reasonably), the Facility shall be shut down in order to permit the parties to undertake a detailed inspection over such period as the parties shall agree to be reasonable in the circumstances.

	BEF	  	=	  	Boiler Efficiency Factor, percent/100
	TAC	  	=	  	Turbine aging correction factor, determined as described in Clause 7.0, Paragraph A of this Appendix 4.

  

	 	C.	Each Performance Test shall be performed at a time selected by, and at the discretion of Buyer. If, due to failure of Seller’s Equipment, an additional Performance Test is
required, Seller shall be responsible for the cost of this retest (excluding fuel and operator costs) based on the scope of testing work allocated to Seller in Material Requisition MRA-MKAA-00001, Appendix A. With respect to any Performance Test,
Buyer may declare a “Completed Performance Test”, which shall establish the time of completion for such test if accepted by Owner. 

 Buyer shall give reasonable notice to Seller prior to the dates on which any Performance Test will be made, it being understood that Seller may require preliminary tests and final adjustments. 
  

	 	D.	The performance of the Equipment demonstrated in each Completed Performance Test will be determined and calculated in accordance with test procedures consistent with Material
Requisition MRA-MKAA-00001, Appendix A, and as mutually established by Seller, Buyer and Owner, which shall include correction factors and adjustment curves. 

  

	 	E.	All test results obtained from the Performance Tests shall be corrected to the Guarantee Conditions in accordance with the Test Procedures for the Facility.

  

	 	F.	All Performance Guarantee Tests shall be accomplished with the Facility operating wholly within its design ratings. 

  

	7.0	TEST PROTOCOLS AND PROCEDURES 

  

	 	A.	Guarantee Conditions 

 All Facility Performance
Test results will be adjusted analytically for deviations from the Guarantee Conditions as set forth in the Facility Test Procedures. 
 Aging or degradation shall not be considered when determining whether the Seller’s Equipment meets the Equipment Performance Guarantees. 
  

	 	B.	Test Interruptions 

 With the exception of the
Reliability Test, any test interruption attributable to Buyer experienced during a Facility Performance Test or Equipment Performance Test will 
  

					
		 	Page 17 of 20	 	
	By Seller:                     	 		 	By Buyer:                     

 require the re-testing of the applicable Facility or Equipment Performance Guarantees. Test data gathered
from the Facility or Equipment Performance Test prior to the interruption shall be discarded. If a test interruption occurs for reasons beyond the control of Buyer, it shall be mutually agreed to either: (a) resume the Facility or Equipment
Performance Test after the cause of the test interruption has been rectified, or (b) restart the Facility or Equipment Performance Test. 
 Upon the occurrence of a Facility or Equipment Performance Test interruption, Buyer shall notify Owner in accordance with the performance test procedure. Upon notification of an interruption, Buyer and/or Seller, with Owner’s
assistance will identify the cause, define the procedure for continuing or stopping the Performance Test or Equipment Performance Test, and identify the responsibility for any costs incurred for re-testing. 
 “Reliability Test Interruption” means any period of time the Facility is out or derated because of Force Majeure, unavailability of fuel, Owner
scheduled outages (other than at Buyer’s request), faults of the electrical grid, and failure of Owner to operate the Facility in accordance with the station operating manuals. Reliability Test Interruptions will be excluded from the
Performance Test period for test data analysis and the Performance Test shall continue when the interruption is corrected. Reliability Test Interruptions will extend the test period by an amount of time equal to the interruption. Reliability Test
data collected before the interruption may be included in the analysis. 
 Periods of exceedance of emissions limits defined in the Air Permit
shall be treated as a Reliability Test Interruption pursuant to the previous paragraph (for the duration of the exceedance period), except for periods during which the emissions exceedance resulted in a Facility derating or shutdown. 
 Upon a Facility trip caused by the Work, Owner will not be required to return the Facility to service unless the root cause of the trip has been
identified and the problem has been corrected. 
  

					
		 	Page 18 of 20	 	
	By Seller:                     	 		 	By Buyer:                     

 Any time period during a test for which a test interruption occurs that is beyond the control of Buyer
and Seller will be excluded from the test period for test data analysis. Any interruption that is the consequence of failure of equipment to meet operating requirements shall not be a test interruption and shall not be excluded from the test period
for test data analysis. Types of interruptions excluded from the test period shall included interruptions caused by Force Majeure, test instrumentation malfunction, unavailability of design fuel or other materials, problems in disposing of discharge
materials, and operating and dispatching decisions and other causes outside Buyer’s and Seller’s control except as otherwise provided with respect to dispatching decisions during the Reliability Test. The Reliability Test periods may, at
Buyer’s option, be continuous except for permitted test interruptions per above. 
 Operator action/inaction, inconsistent with Prudent
Utility Practices, or not in accordance with (or inconsistent with) the performance test procedures, causing a failure to meet the Guaranteed Emissions levels will not constitute an emissions violation or test interruption, unless such action or
inaction is at the direction of Buyer and Seller. Emissions data from an exceedance period attributable to operator action/inaction will be excluded from analysis. All other data collected during such an exceedance period, at Buyer’s and
Seller’s joint option, will be included in the analysis. 
 The failure of nonessential automatic controls and instrumentation will not
preclude initiation of the Reliability Test, or require a Reliability Test interruption if Buyer determines that the failure or unavailability of such instrumentation would not require a Facility shutdown during normal operation. 
  

	C.	Test Procedures 

 Seller shall submit, not later
than 365 Days before the Guaranteed Substantial Completion Date, procedures for the tests which shall include name of item to be tested, location of measurement points, manufacturer and model number of major instruments to be utilized, any
applicable correction curve(s) for off-design conditions, and a verifiable method of calculation (sample calculation) of the test results. 
 The performance of Seller’s Equipment will be based on acceptance tests in accordance with Material Requisition MRA-MKAA-00001, Appendix A. 
 The Performance Tests of the Facility shall be performed using a combination of permanent Facility instrumentation and special test instrumentation for measurements. 
 Seller shall be required to support the overall Performance Test program. Seller-supplied Equipment will be required to be operated in the normal
configuration and be monitored as the Performance Tests are completed. 
 Seller shall report the results of the each Equipment Performance
Test (unless aborted) to Buyer. Buyer may report the results of each Equipment Performance Test to Owner. 
 Seller shall submit a summary
test report within 48 hours after completion of each test performed by Seller. The report shall be sufficient to demonstrate whether the Equipment Performance Guarantees were met (i.e., including corrections of test data to the Reference
Conditions). Buyer shall make available to Seller copies of any summary test report applicable to Seller’s Equipment.

	By Seller:                     	 		 	By Buyer:                     

 Buyer shall submit to Seller a final test report within 18 Days of test completion. This detailed test
report shall include, as a minimum, a description of the equipment tested, the instruments with calibration used for the tests, test uncertainty, test data, results, calculations, laboratory analyses, and application of corrections to Guarantee
Conditions. 
  

	D.	Test Tolerances 

 Application of zero test tolerance
shall apply for the tests and in determining conformance to guarantees. 
 No tolerance, margin, or allowance for uncertainties in measurement
or instrumentation will be allowed in determining conformance to Equipment Performance Guarantee values.

 TXU STANDARD PROJECT 
 PROJECTS          
 SECTION 5, APPENDIX 5

 SCHEDULE GUARANTEES 
  

	1.0	General - Liquidated Damages (LDs) Reasonable 

 The
Parties agree that Buyer would be damaged by Seller’s failure to meet the required dates (“Guaranteed Milestone Dates”) set forth in Articles 2 and 3 of this Appendix 5 and by any failure to achieve Substantial Completion by the date
which is ninety (90) Days prior to the Guaranteed Substantial Completion Date and that Buyer’s actual damages in any such event would be extremely impracticable or impossible to calculate. Accordingly, the Parties agree that Seller’s
liability to Buyer for failure to achieve the specified dates shall be determined by and limited to amounts as specified below, which Seller agrees to pay to Buyer in such event as liquidated damages and not as a penalty. 
 The Parties, having negotiated in good faith for such specific liquidated damages and having agreed that the amount of such liquidated damages is
reasonable in light of the anticipated harm caused by the breach or fault related thereto and the difficulties of proof of loss and inconvenience or nonfeasibility of obtaining any adequate remedy, are estopped from contesting the validity or
enforceability of such liquidated damages. 
 If any sum specified as liquidated damages fails as liquidated damages for any reason, then
Seller shall nonetheless be liable to pay general damages in respect thereof, provided that such general damages shall not exceed the subcap applicable to any liquidated damages that would have been payable in such circumstances. 
 Except as provided herein, each item of liquidated damages appearing in Articles 2, 3 and 4 below shall apply separately and independently of every other
item of liquidated damages appearing in this Appendix 5. To the extent funds withheld by Buyer are not sufficient to pay any and all liquidated damages arising under this Agreement, Seller shall pay such liquidated damages five (5) days after
receipt of Buyer’s claim and invoice. 
 Payment of liquidated damages shall not relieve Seller from its obligation to carry out and
complete the Work in accordance with this Agreement and/or from any other duties, obligations or responsibilities Seller may have under this Agreement and, accordingly, shall not prejudice Buyer’s rights in the event of the failure of Seller to
comply with any such obligations, subject to the provisions of Section 5 (Special Conditions) Clause SC-30 (Limitation of Liability). 
  

	2.0	Drawings, Documentation and Engineering Data 

  

	2.1	Drawings and engineering data for Project 1 shall be submitted by Seller in strict accordance with Section 2 (Technical Specifications) Appendix B of Material Requisition
(“Document Submittal Requirements” (“DSRs”)), shall be complete in all respects and of a high professional quality, and shall be received by Buyer no later than the “Guaranteed Document Milestone Dates” shown in
Section 2 (Technical Specifications) Appendix B of Material Requisition. The Guaranteed Document Milestone Dates are the dates such initial drawings or other documents are to be received by Buyer at the address stipulated in Section 3
(Drawings and Data), subject to Clause 2.7, below. In the case of a DSR requiring a group of documents to be submitted, this means that all of the documents in the group must be received by Buyer on or before the Guaranteed Document Milestone

	By Seller:                     	 		 	By Buyer:                     

 Date therefor. Seller may transmit documents by the most expedient means available including electronic
transmission, provided the date Buyer receives such transmission is no later than the relevant Guaranteed Document Milestone Date. Where electronic transmission has been made, Buyer shall receive one corresponding paper copy within seven
(7) Days of the electronic transmission. The drawings and engineering data submitted with respect to Project 1 shall also apply to each of the remaining seven (7) subsequent Projects in Owner’s Standard Plant Program. Seller shall not
be further obligated to submit any drawings or engineering data for any such subsequent Project. 
  

	2.2	Document Delivery Milestones 

 Seller shall pay the
liquidated damages (“Document Delivery LDs”) as set forth in Table 1.0 for document receipt by Buyer later than the applicable Guaranteed Document Milestone Date unless Seller can show, to Buyer’s reasonable satisfaction, that the
delay is not attributable to Seller; provided, however, document delivery liquidated damages shall only apply to Project 1.

	2.5	In the event that a given “Item Number” as shown in Appendix B Column No 1 includes more than one drawing/document, then Document Delivery LDs for late submittals shall
only be assessed to the individual “Item Number” as a whole and the breakdown of “drawing/document” information on the drawing list shall not be treated as separate submittals for purposes of calculating Document Delivery LDs.
For the avoidance of doubt, Document Delivery LDs shall only be assessed against the delay in submission of the last document submitted within a milestone group/”Item Number”. 

  

	2.6	Additionally, for purposes of assessing Document Delivery LDs, any document submittals, which receive status code 1, 2 or 4 shall be deemed to have been submitted by Seller. If
these status code 1, 2 or 4 documents are subsequently revised by Seller causing rework by Buyer, such rework shall be charged to Seller’s account in accordance with Section 5 (Special Conditions) Clause SC-11 (Backcharges).

  

	2.7	If any document submittal receives a status code 3 then, for the purpose of assessing the liability of Seller to pay Document Delivery LDs, such document shall be deemed not to have
been received by Buyer until a revised or replacement document is received which receives a status code 1, 2 or 4 review stamp. 

  

	2.8	The payment by the Seller to the Buyer of Document Delivery LDs in accordance with this Clause 2.0 of this Appendix 4 shall be the Buyer’s sole and exclusive remedy in full and
final satisfaction of the Seller’s liability for delay in submission of such documents, subject to Buyer’s rights under Section 4 (General Conditions) Clause GC-9 (Termination for Default) and Section 5 (Special Conditions)
Clause SC-4 (Expediting) and subject to Seller’s liability for payment of other liquidated damages specified in this Agreement. 

  

	3.0	Equipment Delivery Milestones 

  

	3.1	Delivery of all Equipment shall be in accordance with the Delivery provisions of this Agreement. Delay in Delivery of specified Equipment items shall be subject to liquidated
damages (“Equipment Delivery LDs”) as indicated in Attachment 1 to this Appendix 5. 

  

	3.2	Seller agrees to guarantee Delivery of Equipment by the dates set forth in Attachment 1 to this Appendix 5 (“Guaranteed Milestone Delivery Dates”) unless such dates have
been extended pursuant to GC-2 and GC-3 and shall be subject to liquidated damages as indicated in Attachment 1 to this Appendix 5, based on the type of Equipment, in the event of delivery of Equipment later than the applicable Guaranteed Milestone
Delivery Date. In addition, in the event that any item of Equipment is found by Buyer to be defective or damaged for reason(s) attributable to Seller, Seller shall be liable to pay Equipment Delivery LDs calculated from
the date the defect or damage is notified by Buyer to Seller until the correction or repair is completed. 

  

	3.3	The Equipment delivery dates that are guaranteed in Attachment 1 to this Appendix 5 are for Delivery of all components in an identified group in accordance with the Delivery
provisions of this Agreement. Equipment Delivery LDs will be assessed based upon the date of Delivery of the last item in an identified group. 

  

	3.4	The payment by Seller to Buyer of Equipment Delivery LDs shall be Buyer’s sole and exclusive remedy in full and final satisfaction of Seller’s liability for delay in
Equipment Delivery, subject to Buyer’s rights under General Conditions GC-9 (Termination for Default) and Special Conditions Clause SC-4 (Expediting) and subject to Seller’s liability for payment of other liquidated damages specified in
this Agreement.

	4.0	Substantial Completion Delay Liquidated Damages 

  

	4.1	If Buyer is delayed from achieving Substantial Completion by the date which is ninety (90) Days prior to the Guaranteed Substantial Completion Date (as such date may be
extended from time to time under the Prime Contract) and such delay is caused either solely or in part by a deficiency in the Equipment or by the acts or omissions of Seller or its Subcontractors, it is agreed that Buyer will be damaged in an amount
that will be difficult to ascertain. Therefore, Seller shall be liable to Buyer for payment of the amounts specified below, as liquidated damages and not as a penalty. If the delay is caused by reason(s) that are solely attributable to a deficiency
in the Equipment or the acts or omissions of Seller or its Subcontractors, Seller shall be liable to Buyer for the amounts specified below. If the delay is caused by reason(s) that are not solely attributable to a deficiency in the Equipment or the
acts or omissions of Seller or its Subcontractors, Seller shall be liable to Buyer for an amount equal to the proportionate share of Seller’s responsibility for the amounts specified below.

	4.2	Subject to Clause 4.3 below, Buyer will provide reasonable access to the Equipment for a total duration of forty five (45) Days for the start up and commissioning of the
Equipment commencing from the First Fire (on coal). Buyer shall endeavor to provide any additional access time to Seller, if available, within the overall start up and commissioning period from the commencement of First Fire (on coal) to ninety
(90) Days prior to Guaranteed Substantial Completion Date, so long as such additional access time does not compromise or interfere with Buyer’s other commissioning activities. 

  

	4.3	The forty five (45) Days described in Clause 4.2 above shall be reduced by the number of Days that the cumulative impact of delays in delivery of Equipment causes First Fire
(on coal) to be delayed. In addition, in the event that all other equipment and systems in the Facility are ready to support First Fire (on coal), and a defect or deficiency with respect to the Equipment is the primary cause of a delay in the First
Fire (on coal) date, such forty five (45) Days also shall be reduced one Day for each Day of delay caused primarily by such defect or deficiency with respect to the Equipment. 

  

	4.4	If Buyer is unable to provide the forty five (45) Days described in Clause 4.2 above (or such lesser number of Days as provided in Clause 4.3 above) for reasons not
attributable to Seller, then Days of delay will not be allocated to the Seller (hence no liability to the Buyer for Substantial Completion LDs shall apply) until Buyer has provided Seller with a total duration of forty five (45) Days (or such
lesser number of Days as provided in Clause 4.3 above) for the start up and commissioning of the Equipment.

	4.5	For the purposes of calculating the number of Days for the start up and commissioning of the Equipment, if Seller has access to the Equipment to perform start up related activities
required for operation and the achievement of Substantial Completion, that Day shall be counted as a Day for the start up and commissioning of the Equipment. 

  

	4.6	For the avoidance of any doubt, if Buyer fails to make the Equipment available as contemplated by Clause 4.2 above that Day will not be counted as a Day for the start up and
commissioning of the Equipment. Conversely, if Buyer makes the Equipment available as contemplated by the preceding paragraph and Seller elects not to perform startup activities, that Day will be counted as a Day for the start up and commissioning
of the Equipment. 

  

	4.7	It shall be understood that all Parties will actively participate in the coordination and scheduling of startup related activities to achieve Substantial Completion in an organized,
effective and efficient manner. 

  

	4.8	Further understandings in respect of the Substantial Completion LDs are set out below: 

  

	 	(i)	Buyer (acting reasonably) shall determine responsibility for delays as between Buyer, Seller and Buyer’s other contractors and suppliers. If and to the extent that such delay
is in Buyer’s opinion (acting reasonably) the responsibility of Seller, Buyer (acting reasonably) shall assess and apportion responsibility to the Seller. 

  

	 	(ii)	Buyer shall give written notice to Seller of any determination of responsibility under this Clause 4.0, and of any resulting assessment and obligation to pay liquidated damages to
Buyer. Buyer will promptly provide Seller with full details of all relevant calculations and with copies of all relevant schedules, correspondence and other documents upon which such determination, assessment and attribution were based.

  

	 	(iii)	With respect to Substantial Completion LDs for the period after the Guaranteed Substantial Completion Date, if Owner does not assess liquidated damages for failure to achieve
Substantial Completion under the Prime Contract, Buyer shall not be entitled to assess Substantial Completion LDs against Seller under this Agreement for the period after the Guaranteed Substantial Completion Date. For the avoidance of doubt the
foregoing shall not apply to Seller’s liability for payment of Substantial Completion LDs for the period prior to the Guaranteed Substantial Completion Date. 

  

	 	(iv)	For informational purposes, Buyer has been provided a period of ninety (90) Days for the start-up and commissioning activities of the Facility from the commencement of First
Fire (on coal) until ninety (90) Days prior to the Guaranteed Substantial Completion Date. 

  

	 	(v)	Buyer will complete those checkout activities that are to be performed prior to First Fire (on coal) in accordance with Seller’s recommended commissioning schedule approved by
Buyer.

 PARENT COMPANY GUARANTEE 
 This
Guarantee given and delivered by ALSTOM Holdings whose registered office is at 3 Avenue André Malraux, 92300 Levallois-Perret Cedex, France, herein called “Guarantor”, to TXU Generation Development Company LLC, herein called
“Buyer,” with respect to Purchase Order Number 25262- -POA-MKAA-00001                 , dated
[            ] (herein called “Purchase Order”) between Buyer and [Name of Seller] for the supply of Air Quality Control System and associated equipment for the TXU Standard Multi
Plant, Texas, USA. 
 WITNESSETH 
 That in
order to induce Buyer to enter into the Purchase Order with [Name of Seller] (herein called “Affiliate”), an affiliated company of Guarantor, and in consideration of Buyer entering into the Purchase Order with Affiliate, the Guarantor has
determined that executing this Guarantee is in its interest and to its financial benefit and it is hereby agreed as follows: 
  

	1.	Guarantor, for itself, its successors and permitted assigns, hereby irrevocably and unconditionally guarantees to Buyer, its successors and permitted assigns, as primary obligor and
not as surety, the full and faithful performance by Affiliate, its successors and assigns of each and every one of the terms, provisions, conditions, obligations and agreements on the part of Affiliate to be carried out, performed or observed as
provided in the Purchase Order. 

  

	2.	If at any time default is made by Affiliate in the performance of any of the terms, provisions, conditions, obligations and agreements under the Purchase Order or in the payment of
any sums payable pursuant thereto which are to be made, carried out, performed, paid or observed by Affiliate, Guarantor will well and truly perform, or cause to be so performed, such terms, provisions, conditions, obligations and agreements under
the Purchase Order including the payment on demand of any sums payable pursuant thereto. All payments by Guarantor hereunder shall be made in full, without set-off or counterclaim and free and clear of any deductions or withholdings in immediately
available, freely transferable, cleared funds to the account of Buyer as notified to Guarantor by Buyer. 

  

	3.	Guarantor agrees that its obligations hereunder shall not be discharged nor shall they be affected by reason of: (i) any legal limitations, disabilities, incapacities or want
of powers on the part of Affiliate to enter into the Purchase Order; or (ii) the invalidity or unenforceability of the obligations of Affiliate under the Purchase Order arising from or related to the liquidation, winding up or dissolution of
Affiliate; or (iii) the appointment of or acts of a receiver or liquidator on behalf of Affiliate (including, without limitation, the ability of any liquidator of Affiliate to disclaim obligations of Affiliate arising under the Purchase Order).

  

	4.	Guarantor covenants and agrees with Buyer, its successors and permitted assigns that (i) waiver by Buyer of any of the terms, provisions, conditions, obligations and agreements
of the Purchase Order, (ii) any modification or changes to the Purchase Order, (iii) the giving of any consent to an assignment or the making of any assignment of the Purchase Order and (iv) the granting of extensions of time to
Affiliate, its successors and permitted assigns may all or any of them be made and done without notice to Guarantor and without in any way affecting, changing or releasing Guarantor from its obligations given under this Guarantee, and such changes
or extensions of time may be granted, such waiver and consents may be given and such modifications and assignments may be made without notice to or the consent of Guarantor and without impairing the obligations of the Guarantee hereby given.

	By Seller:                     	 		 	By Buyer:                     

	5.	Buyer may enforce this Guarantee without first making demand on, or taking any proceeding against, Affiliate or resorting to any other security, guarantee or other means of payment
and no action (or inaction) by Buyer in respect of any such security, guarantee or other means of payment shall prejudice or affect Buyer’s rights under this Guarantee. The Guarantor irrevocably waives acceptance hereof, presentment, demand,
protest and, to the fullest extent permitted by law, any notice not provided for herein. 

  

	6.	Nothing herein shall be construed as imposing greater obligations and liabilities on the Guarantor than are imposed on the Affiliate under the Purchase Order and the
Guarantor’s cumulative liability hereunder shall be limited to [insert Agreement Price]. Notwithstanding anything to the contrary herein, the Guarantor shall be entitled to all defenses, limitations and exclusions available to the
Affiliate under the Purchase Order. 

  

	7.	If a demand, in accordance with this Guarantee, is made upon the Guarantor and the Guarantor duly and properly performs the obligations of Affiliate then, to that extent only,
Affiliate shall be released from such obligations by the Buyer. 

  

	8.	This Guarantee shall expire upon final fulfillment by Affiliate of all its obligations under the Purchase Order or in lieu thereof by Guarantor under this Guarantee and shall in any
event expire on [LONG STOP DATE TO BE INSERTED]. Upon the date of expiry, this Guarantee shall be of no further effect, except in respect of claims or demands made under this Guarantee on or before such expiry date. Upon expiry of this Guarantee,
the original signed Guarantee shall be returned to Guarantor. 

  

	9.	Upon prior written notice to the Guarantor, this Guarantee may be assigned by Buyer to any legal entity or entities to whom Buyer’s rights and/or obligations under the Purchase
Order are validly assigned in accordance with its terms 

  

	10.	Guarantor represents and warrants that: 

 (a) It is a
corporation, partnership or limited liability company duly and properly incorporated or organized, as the case may be, validly existing and (to the extent such concept applies to such entity) in good standing under the laws of its jurisdiction of
incorporation or organization and has all requisite authority to conduct its business in each jurisdiction in which its business is conducted. 
 (b) It has the power and authority and legal right to execute and deliver this Guarantee and to perform its obligations hereunder. The execution and delivery by it of this Guarantee and the performance of its obligations hereunder have been
duly authorized by proper corporate proceedings, and this Guarantee constitutes a legal, valid and binding obligation of Guarantor enforceable against it in accordance with its terms. 
 (c) Neither the execution and delivery by it of this Guarantee, nor the consummation of the transactions herein contemplated, nor compliance with the
provisions hereof will violate (i) any law, rule, regulation, order, writ, judgment, injunction, decree or award binding on it or any of its subsidiaries applicable as at the date of this Guarantee or (ii) its articles or certificate of
incorporation, partnership agreement, certificate of partnership, articles or certificate of organization, by-laws, or operating or other management agreement, as the case may be, or (iii) the provisions of any indenture, instrument or
agreement to which it or any of its subsidiaries is a party or is subject, or by which it is bound, or conflict with or constitute a default thereunder. No

 order, consent, adjudication, approval, license, authorization, or validation of, or filing, recording or
registration with, or exemption by, or other action in respect of any governmental or public body or authority, or any subdivision thereof, which has not been obtained by it or any of its subsidiaries, is required to be obtained by it or any of its
subsidiaries in connection with the execution and delivery of this Guarantee or the performance by it of its obligations hereunder or the legality, validity, binding effect or enforceability of this Guarantee. 
  

	11.	This Guarantee is governed by, and shall be construed in accordance with, the laws of the State of Texas without reference to the conflict of laws rules thereof. This Guarantee is
intended to be fully enforceable in accordance with its terms and constitutes a guarantee of Affiliate’s obligations and liabilities arising out of or in connection with the Purchase Order. In the event that any issue, matter or dispute arises
under the Purchase Order which is resolved under the Purchase Order, including any issue, matter or dispute which is resolved in accordance with the dispute resolution provisions under the Purchase Order, such issue, matter or dispute shall be
deemed to have been conclusively determined for the purpose of this Guarantee and neither party to this Guarantee will thereafter take any steps to argue that such issue, matter or dispute should be resolved under this Guarantee in any different
manner from the resolution under the Purchase Order and the parties waive any right to do so. 

  

	12.	Each of the parties hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any Texas State court or federal court of the
United States of America sitting in Texas, and any appellate court from any thereof in any action or proceeding arising out of or relating to this Guarantee or for recognition or enforcement of any judgment. Guarantor hereby irrevocably appoints
ALSTOM Power Inc., 2000 Day Hill Road, Windsor, CT 06095-1521 as its agent for service of process, provided that a copy of any notice under this Guarantee is also provided to Guarantor by first class recorded delivery post or by a recognized
overnight post or courier service with delivery receipt requested. Each party agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law. 

  

	 	(a)	Guarantor irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue
of any suit, action or proceeding arising out of or relating to the Purchase Order and Guarantee in any Texas State or federal court. Guarantor hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum
to the maintenance of such suit, action or proceeding in any such court. 

  

	 	(b)	To the extent Guarantor has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service or notice, attachment prior to
judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property based on place of personal jurisdiction, Guarantor hereby irrevocably waives such immunity with respect to its obligations under the Guarantee.

  

	 	(c)	EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LEGAL REQUIREMENTS, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY MATTER DIRECTLY OR
INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS GUARANTEE OR THE PURCHASE ORDER. EACH PARTY HERETO (i) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER
PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, AND (ii) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN

executing this Guarantee is in its interest and to its financial benefit and it is hereby agreed as follows: 
  

	1.	Guarantor, for itself, its successors and permitted assigns, hereby irrevocably and unconditionally guarantees to Seller, its successors and permitted assigns, as primary obligor
and not as surety, the full and faithful performance by Devco, its successors and assigns of each and every one of the terms, provisions, conditions, obligations and agreements on the part of Devco to be made, carried out, performed or observed as
provided in the Purchase Order. 

  

	2.	If at any time default is made by Devco in the performance of any of the terms, provisions, conditions, obligations and agreements in the Purchase Order or in the payment of any
sums payable pursuant thereto which are to be made, carried out, performed, paid or observed by Devco, Guarantor will well and truly perform, or cause to be so performed, such terms, provisions, conditions, obligations and agreements in the Purchase
Order. Save as provided in and subject to the terms of this Guarantee, any monies which are payable by Devco pursuant to the Purchase Order which may not be recoverable from Devco shall nevertheless be recoverable by Seller from Guarantor as if
Guarantor were principal debtor. All payments by Guarantor hereunder shall be made in full, without set-off or counterclaim and free and clear of any deductions or withholdings in immediately available, freely transferable, cleared funds to the
account of Seller as notified to Guarantor by Seller. 

  

	3.	Guarantor agrees that its obligations hereunder shall not be discharged nor shall they be affected by reason of: (i) any legal limitations, disabilities, incapacities or want
of powers on the part of Devco to enter into the Purchase Order; or (ii) the invalidity or unenforceability of the obligations of Devco under the Purchase Order arising from or related to the liquidation, winding up or dissolution of Devco; or
(iii) the appointment of or acts of a receiver or liquidator on behalf of Devco (including, without limitation, the ability of any liquidator of Devco to disclaim obligations of Devco arising under the Purchase Order). 

 

	4.	Guarantor covenants and agrees with Seller, its successors and permitted assigns that (i) waiver by Seller of any of the terms, provisions, conditions, obligations and
agreements of the Purchase Order, (ii) any modification or changes to the Purchase Order, (iii) the giving of any consent to an assignment or the making of any assignment of the Purchase Order and (iv) the granting of
