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



|           |  |              |  |

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



|4.1 | All Work furnished by Seller hereunder shall become the property of Buyer or Owner, as applicable upon (i) payment therefor, (ii) or shipment to the Jobsite, or
(iii) incorporation

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

|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

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;

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.

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

|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.

|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.

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

to such drawings in accordance with this Agreement.

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.

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.

|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

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.

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

|EEAF Ranges   |  | Reliability Liquidated Damages
|Less than 99% |  | $*** per % point shortfall    

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 = {[(AF1x
DP1) + (AF2x DP2) + ... + (AFnx DPn)] ÷ TP} x

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



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

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



| | 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

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.

---

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.

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.

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).

(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.

|3.1 | 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.

SECTION 5  APPENDIX 8

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

WITNESSETH

That in order to induce Seller to enter
into the Purchase Order with TXU Generation Development Company LLC (herein called Devco), an affiliated company of Guarantor, and in consideration of Seller entering into the Purchase Order with Devco, 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 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

extensions of time to Devco, 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.



|5. | Seller may enforce this Guarantee without first making demand on, or taking any proceeding against, Devco or resorting to any other security, guarantee or other means of payment and
no action (or inaction) by Seller in respect of any such security, guarantee or other means of payment shall prejudice or affect Seller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. | The liability of the Guarantor under this Guarantee shall in no event be greater than that of Devco under the Purchase Order and the Guarantors cumulative liability hereunder
shall be limited to [insert the Agreement Price]. The Guarantor shall have available to it, in any action or proceeding by Seller seeking performance of this Guarantee, or damages for its non-performance of this Guarantee, all defenses and
counterclaims which Devco would be able to raise in an action by Seller against Devco seeking performance or damages for non-performance 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 Devco then, to that extent only, Devco
shall be released from such obligations by the Seller.
|-- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|8. | Upon written notice to Seller, Guarantor may, without Sellers consent, assign its obligations under this Guarantee to any of its Affiliates (as such term is defined in

determined by either Standard & Poors or Moodys (or if either one or both are not available, an equivalent rating from an alternative rating source reasonably acceptable to Seller).
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Upon the assignment of Guarantors obligations hereunder to any permitted assignee, and such permitted assignees assumption in writing in of
such obligations, Guarantor shall be deemed released from and shall have no further rights, obligations, responsibilities or liabilities under this Guaranty.

Guarantor shall be deemed released from and shall have no further obligations, responsibilities or liabilities under this Guaranty on the earlier of (x) the date Devco assigns the rights and obligations of the
Purchase Order to Bechtel Power Corporation or another nationally recognized engineering, procurement and construction contractor as permitted in the Purchase Order and (y) the date Devco has written commitments from lenders or equity investors
(where the lead lender or investor has a Tangible Net Worth (as defined below) of at least One Hundred Fifty Million Dollars ($150,000,000) and an equivalent or higher credit rating than the Threshold Rating) to provide financing for the Project in
an amount equal to or no less than the portion of the remaining obligations then remaining to be paid under the Purchase Order. Tangible Net Worth shall mean the sum of (i) assets, including permits, contracts and leases,
