Without limiting the generality of the foregoing, if Owner and Operator agree that Operator’s costs of performing the Work are materially increased or decreased as a result of any Change in Law or any change to any agreement, instrument or document referred to herein relating to the Plant, in each case occurring after the date hereof and affecting the scope of Operator’s responsibilities under this Agreement, then Owner and Operator shall agree upon an equitable adjustment to Operator’s Compensation whereby, as applicable, either (i) Operator shall be entitled, upon submission of proper invoices and supporting documentation, to be reimbursed for such increased costs or (ii) the Compensation shall be reduced by the amount of such decreased costs, which adjustment shall, in each case, be reflected in a written Change Order. If any such change in scope is initiated by Operator, Operator shall notify Owner of its estimate of the increased or decreased costs caused by such change in scope at or prior to the time the relevant Change Order is submitted to Owner for approval.

5.             ADDITIONAL SERVICES.

5.1          Operator’s Authority. Operator shall have the authority to enter into purchase orders on behalf of Owner or a Project Company in a form approved by Owner, as the agent of Owner or such Project Company, in order to obtain the performance of Additional Services for the Plant from independent third parties; provided that such purchase order is not expected to be in excess of $10,000 and that the amount of such purchase order will not exceed the budgeted amount for such Additional Service set forth in the Annual Maintenance Plan by more than $2,000. If a purchase order would result in expenditures in excess of $10,000 or cause the budgeted amount for such Additional Services to exceed the amount set forth in the Annual Maintenance Plan by more than $2,000 or if the Additional Service requires an agreement in a form substantially different from the form of purchase order approved by Owner, Operator shall not enter into such purchase order without Owner’s prior written consent. Owner shall pay, or shall cause the applicable Project Company to pay, the contractor performing under any such purchase order directly, and Operator shall have no liability or responsibility to pay any such contractor out of its own funds. Notwithstanding the foregoing, during an Emergency, Operator is authorized to make such expenditures and take such other actions, whether budgeted or not, as Operator shall reasonably determine to be necessary in order to comply with this Agreement, applicable Permits, Laws or to otherwise protect the Plant, individuals or other property and to maintain the Plant in a safe condition consistent with Prudent Operating Practices. If any such

13

unbudgeted costs and expenditures are incurred, Operator shall promptly notify Owner of such action, specifying the particulars of the events giving rise to such costs and expenditures, and shall promptly submit a revision to the Annual Maintenance Plan to encompass the costs and expenditures incurred, as well as those expected to be incurred, as a result of such Emergency or other unexpected event, and such costs and expenditures shall be paid directly by Owner or the applicable Project Company or reimbursed to Operator if incurred directly by Operator.

5.2          Parts. Materials, equipment and parts procured by Operator on Owner’s behalf shall be inspected and tested by Operator in accordance with Prudent Operating Practices and any obvious defects shall be noted and handled appropriately.

6.             COOPERATION.

6.1          General. During the term of this Agreement, each Party shall provide such reasonable assistance and cooperation as the other Party may request in connection with the performance of their respective duties and obligations under this Agreement.

6.2          Owner Representative. From time to time during the Term, Owner shall designate, by written notice signed by an executive officer of Owner delivered to Operator, an individual and an alternate (to act in the absence of such representative) (each, an “Owner Representative”) with authority to act for Owner in all matters pertaining to this Agreement and the Plant, to receive notices and communications from Operator with respect to this Agreement and the Plant, and to deliver to Operator, on behalf of Owner, notices, communications, decisions and approvals with respect to this Agreement and the Plant. The name of the Owner Representative (including the alternate) as of the date hereof are attached hereto as Exhibit G. In the event that Owner replaces an Owner Representative (or such alternate), Owner shall promptly notify Operator and Operator shall prepare and distribute a new Exhibit G reflecting such changes.

6.3          Actions by Owner. The manner of making any decision or giving any approval by Owner shall be determined by Owner for itself, but any communication received by Operator from a Person designated by Owner as its Owner Representative (unless such designation shall have been previously revoked) may be conclusively relied upon by Operator as having been authorized by Owner.

6.4          Operator Representative. From time to time during the Term, Operator shall designate, by written notice signed by an executive officer of Operator delivered to Owner an individual and an alternate (to act in the absence of such representative) (each, an “Operator Representative”) with authority to act for Operator in all matters pertaining to this Agreement and the Plant, to receive notices and communications from Owner with respect to this Agreement and the Plant, and to deliver to Owner, on behalf of Operator, notices, communications, decisions and approvals with respect to this Agreement and the Plant. The name of the Operator Representative (including the alternate) as of the date hereof are attached hereto as Exhibit G. In the event that Operator replaces an Operator Representative (or such alternate), Operator shall promptly notify Owner and Operator shall prepare and distribute a new Exhibit G reflecting such changes.

14

6.5          Actions by Operator. The manner of making any decision or giving any approval by Operator shall be determined by Operator for itself, but any communication received by Owner from a Person designated by Operator as its Operator Representative (unless such designation shall have been previously revoked) may be conclusively relied upon by Owner as having been authorized by Operator.

6.6          Access to Information; Special Assistance. Operator shall provide Owner access to all documents, data, logs, reports, information and records that relate to operation and maintenance of the Plant and the performance by Operator of its obligations hereunder; provided, however, that Operator shall not be required to provide any privileged or proprietary information, personnel information, or other information that does not relate to the Plant or the Work and otherwise is not required to operate and maintain the Plant in accordance with Prudent Operating Practices. At the request of Owner from time to time, Operator shall provide Owner with such data and assistance as may be reasonably requested by Owner to enable Owner to discharge satisfactorily its responsibilities as Owner of the Plant, including its responsibilities to its Financing Parties, security holders, regulatory authorities and others, including by making the Operator’s personnel available for consultation.

7.             OWNER’S RESPONSIBILITIES.

7.1          Responsibilities of Owner. Owner shall be responsible for the following:

(a)                                 Providing Operator and its subcontractors with access to and within the Plant at all times and without prior notice as reasonably necessary for Operator to perform the Work;

(b)                                 If Owner brings third parties onto the Plant site, Owner shall give Operator at least two (2) Business Days’ prior written notice of such third party visit, and Owner shall comply, and be responsible for each third party’s compliance, with the safety requirements of the Plant site and any operating or other procedures or protocols related to the Plant.

(c)                                  Power sales, including all communications, contracting, bidding, scheduling and accounting in connection therewith;

(d)                                 Providing facilities for Operator’s Plant Personnel and any Services Providers’ personnel, including adequate storage, work areas and restrooms;

(e)                                  Obtaining all Permits or licenses required by a Governmental Authority to be in Owner’s name which are necessary to enable Operator or its subcontractors to operate and maintain the Plant;

(f)                                   Water supply, telephone service, public address system, local data network, in—plant radio system, water and waste disposal (other than Hazardous Materials) and all other utilities as deemed desirable by mutual agreement of Owner and Operator for the execution of the Work; and

15

(g)          Paying all amounts owed to third party Services Providers in connection with their provision of Additional Services, including any such contracts signed on Owner’s behalf pursuant to Section 5.1.

8.             COMPENSATION AND PAYMENTS.

8.1          Compensation. During the term of this Agreement, Owner shall pay to Operator in twelve (12) equal monthly installments, as compensation for performance of its duties and obligations hereunder, the Compensation determined and payable pursuant to Exhibit E.

8.2          Invoices. At the end of each month during the Term, Operator shall invoice Owner for the Compensation owed for such month; provided that with respect to any partial month during the Term, such payment shall be made pro rata based on the number of days in such month. At Owner’s request, Operator shall allocate such Compensation among the Projects pro rata based on the MW capacity of each Project. Owner shall pay, or cause each Project Company to pay its share of, Contractor’s invoice within fifteen (15) days after its receipt of such invoice.

8.3          Interest on Delinquent Funds. Any delinquent payment under this Agreement shall bear interest, from the date due until paid, at a rate per annum equal to the prime rate from time to time published in The Wall Street Journal (or such successor publication as shall be agreed by Owner and Operator) as the prime lending rate or “prime rate”, plus one percent (1%), but not in excess of the maximum lawful rate of interest permitted by any applicable Laws. Each change in the interest rate payable on delinquent payments hereunder shall become effective on the date of each such change in the prime rate. The payment of any such interest shall not excuse or cure any delinquent payment due to either Party under this Agreement.

8.4          No Waiver. No payment by Owner shall prejudice or constitute a waiver of its right, within the time frame set forth in Section 14, to audit or make a Claim in respect of the correctness of any billing submitted by Operator.

9.             COMPLIANCE WITH LAWS AND PERMITS.

9.1          Requirements of Law Generally. Operator shall comply with all Laws applicable to Operator’s performance of the Work. Owner shall comply with all Laws applicable to its obligations hereunder and otherwise applicable to the ownership by the Project Companies of the Plant.

9.2          Environmental Compliance. Operator shall be responsible for the on—site management of all Hazardous Materials generated by or used in the operation or maintenance of the Plant. Each Project Company shall be identified to any Governmental Authority as the party responsible for the generation, treatment, storage and disposal of all hazardous or toxic wastes (including waste Hazardous Materials) generated by or used in the operation or maintenance of the portion of the Plant relating to the Project owned by such Project Company (and, therefore, such Project Company shall be designated as the “generator” on all manifests relating to all such hazardous or toxic wastes). Operator shall use commercially reasonable and diligent efforts to prevent the release of any Hazardous Materials into the air, soil, surface water or groundwater at

16

the Plant (other than as permitted by applicable Environmental Laws), but Operator shall not be responsible for any Hazardous Materials introduced into the air, soil, surface water or groundwater at or from the Plant, unless such introduction or release of Hazardous Materials was caused by Operator’s willful action, negligence or a breach by Operator of its obligations hereunder. Owner shall indemnify, defend, and hold harmless Operator, its Affiliates and all of their respective officers, directors, employees and representatives (other than the Owner) from and against any Claims (i) arising out of or related to the performance of Operator’s obligations under this Section 9.2 or its procurement and management of Additional Services contracted pursuant to Section C(1)(vii) of Exhibit B or (ii) directly or indirectly related to or arising out of the actual or alleged existence, generation, use, collection, treatment, storage, transportation, recovery, removal, discharge or disposal of Hazardous Material at the Plant, except with respect to any such Claims arising from the willful misconduct, negligence or a breach by Operator of its obligations hereunder. Operator shall indemnify, defend and hold harmless Owner, each Project Company and their respective Affiliates and all of their respective officers, directors, employees and representatives (including the Administrator, but excluding the Operator) from and against any Claims (i) arising out of or related to the performance of Operator’s obligations under this Section 9.2 or its procurement and management of Additional Services contracted pursuant to Section C(1)(vii) of Exhibit B or (ii) directly or indirectly related to or arising out of the actual or alleged existence, generation, use, collection, treatment, storage, transportation, recovery, removal, discharge or disposal of Hazardous Material at the Plant, in each case, to the extent such Claims arise from the willful misconduct, negligence or a breach by Operator of its obligations hereunder.

9.3          Compliance with Permits. Operator shall comply with all Permits, and the terms and conditions thereof, applicable to the Plant (whether such Permits are issued in the name of Operator or Owner).

10.          INDEMNIFICATION AND LIMITATION OF DAMAGES.

10.1        Basis of Compensation. Operator is willing to perform Work for Owner and the Project Companies under this Agreement only if Operator has no exposure to loss, risk or liability other than as set forth in Section 9.2, this Section 10 and Section 11. Notwithstanding any other provision of this Agreement, Operator’s total liability to Owner and its Affiliates for any reason whatsoever shall be strictly limited in accordance with Section 10.3.

10.2        Disclaimers. Operator agrees to perform the Work under this Agreement in accordance with the standards and requirements set forth in Section 3 and otherwise in accordance with the terms of this Agreement. Operator’s liability for failure to comply with such standards and requirements shall be limited as set forth in Section 9.2, this Section 10 and Section 11. Operator makes no other guarantees or warranties of any kind in connection with the performance of the Work. OPERATOR EXPRESSLY DISCLAIMS ALL OTHER WARRANTIES OF ANY NATURE WHATSOEVER, WHETHER STATUTORY, ORAL, WRITTEN, EXPRESS OR IMPLIED, INCLUDING ANY IMPLIED CONDITIONS OR WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Except to the extent expressly provided otherwise in this Section 10 (but subject to Section 10.3 hereof) and Owner’s right to terminate this Agreement under Section 2.2, Operator shall have no liability under this Agreement for any failure, breach or default of its obligations.

17

10.3                        Total Limitation of Operator’s Liability. The maximum aggregate liability of Operator for any action taken or omitted to be taken by Operator or its employees which arises out of or relates to the Work performed under this Agreement, or any action taken or omitted to be taken by Operator or its employees in connection with this Agreement shall not exceed an amount, at any time, in excess of the aggregate amount of Compensation paid (or then payable) to Operator as of such time; provided, however, the foregoing limitation on liability shall not apply to (i) damage to Owner caused by the gross negligence or willful misconduct of Operator with respect to the subject matter of this Agreement, (ii) amounts owed to third parties for which Operator is obligated to indemnify an Owner Indemnified Party under this Agreement, but only to the extent any such amount is contemplated to be covered by insurance required to be obtained by Operator pursuant to Section 12 hereof, and does not exceed the amount of insurance required to be obtained thereby, or (iii) any amounts recoverable by Operator as an insurance payment.

10.4                        Indemnifications.

10.4.1 Operator shall defend and indemnify and hold harmless Owner, each Project Company and their respective shareholders, members, directors, managers, officers and employees (each, an “Owner Indemnified Party”) from and against any and all Claims asserted by or against such Owner Indemnified Party (i) in respect of any taxes imposed on or attributable to the income or property of the Operator, (ii) in respect of liens or encumbrances arising by, through or under Operator in violation of Section 15.2, (iii) in respect of the employer/employee-related responsibilities with respect to any Plant Personnel, including specifically payroll taxes, workers’ compensation claims, any withholdings required by Law, and health and welfare benefits, including COBRA benefits, (iv) relating to the injury or death of any person, including employees of Operator, (v) resulting from loss or damage to property or (vi) relating to the failure of Operator to comply with the terms of this Agreement; provided, however, in the case of clauses (iv), (v) and (vi) only to the extent the Claim results from the willful misconduct, negligence or a breach by Operator of its obligations hereunder.

10.4.2 Owner shall defend and indemnify and hold harmless Operator and its shareholders, members, directors, managers, officers and employees (each, an “Operator Indemnified Party”) from and against any and all Claims asserted by or against such Operator Indemnified Party, including Claims in favor of any Project Company’s electric customers (or any Person claiming by, through or under any Project Company’s electric customers), (i) in respect of any taxes imposed on or attributable to the income or property of the Owner or any Project Company, (ii) relating to the injury or death of any person, including employees of Owner or any Project Company, (iii) resulting from loss or damage to property, (iv) relating to the failure of Owner to comply with the terms of this Agreement or (v) arising out of or related to Operator’s performance of the Work, except, in the case of clauses (ii), (iii), and (v), to the extent resulting from the willful misconduct, negligence or a breach by Operator of its obligations hereunder.

10.4.3 For the avoidance of doubt, no claim or liability for indemnification for environmental claims or any nature shall be made or incurred under this Section 10.4, and such claim or liability shall only be made or incurred pursuant to Section 9.2.

18

10.5                        Indemnification Procedure. When required to indemnify an indemnified Party (the “Indemnified Party”) in accordance with Section 9.2 or this Section 10, the Operator or the Owner, as applicable (in such capacity, the “Indemnifying Party”) shall assume on behalf of such Indemnified Party and conduct with due diligence and in good faith the defense of any Claim against such Indemnified Party and shall bear the expense thereof, whether or not the Indemnifying Party shall be joined therein, and the Indemnified Party shall cooperate with the Indemnifying Party in such defense. The Indemnifying Party shall have charge and direction of the defense and settlement of such Claim, provided, however, that without relieving the Indemnifying Party of its obligations hereunder or impairing the Indemnifying Party’s right to control the defense or settlement thereof, the Indemnified Party may elect to participate through separate counsel in the defense of any such Claim, but the fees and expenses of such counsel by such Indemnified Party shall be at the expense of such Indemnified Party unless (a) the employment of counsel by such Indemnified Party has been authorized in writing by the Indemnifying Party, (b) the Indemnified Party shall have reasonably concluded that there exists a material conflict of interest between the Indemnifying Party and such Indemnified Party in the conduct of the defense of such Claim (in which case the Indemnifying Party shall not have the right to control the defense or settlement of such Claim on behalf of such Indemnified Party) or (c) the Indemnifying Party shall not have employed counsel reasonably acceptable to the Indemnified Party to assume the defense of such Claim within a reasonable time after notice of the commencement thereof. In each of such cases set forth in the second sentence of this paragraph, the reasonable fees and expenses of counsel shall be at the expense of the Indemnifying Party except where the Indemnifying Party is ultimately deemed not to have been required to provide the indemnity sought by the Indemnified Party.

10.6                        Exculpation. OWNER ACKNOWLEDGES TO OPERATOR THAT, EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN SECTIONS 9.2, 10.3, 10.4 AND 10.5, THE PROVISIONS OF THIS SECTION 10 WHICH RELEASE OPERATOR FROM LIABILITY OR PROVIDE FOR THE INDEMNIFICATION OF OPERATOR BY OWNER ARE INTENDED BY OWNER, TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, TO RELEASE AND SAVE AND HOLD HARMLESS OPERATOR FROM ANY STRICT LIABILITY ARISING OUT OF OR RELATING TO THE FURNISHING OF SERVICES OR WORK UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY ACTION TAKEN OR OMITTED TO BE TAKEN BY OPERATOR OR ITS EMPLOYEES IN CONNECTION WITH THIS AGREEMENT.

10.7                        Availability of Insurance. Notwithstanding anything to the contrary in Section 9.2 or this Section 10, the obligation of either Party to indemnify any other party for any Claims will be reduced to the extent of any insurance proceeds received by the Indemnified Party with respect to the indemnified Claims.

10.8                        Survival. Notwithstanding any other provision of this Agreement, the provisions of Section 9.2, this Section 10 and Section 11 are intended to and shall survive the termination of this Agreement so as to cover all Claims instituted within the period set forth in the applicable statute of limitations.

11.                               CONSEQUENTIAL DAMAGES; DISCLAIMER. Neither Party (nor its officers, member, directors or employees) shall be liable to the other Party for any punitive, incidental,

19

indirect, special or consequential loss or damage, including loss of revenues, income or profits, cost of capital, loss of goodwill or reputation connected with or resulting from performance or non-performance of any obligations under this Agreement. The Parties further agree that this waiver and disclaimer of liability shall apply at all times, whether in contract, equity, tort or otherwise, regardless of the fault, negligence (in whole or in part), strict liability, breach of contract or breach of warranty of the Party whose liabilities are so limited.

12.                              INSURANCE. Operator and Contractor shall each maintain the types and amounts of insurance coverages described in Exhibit C and shall otherwise comply with the terms and conditions set forth in Exhibit C.

13.                               FORCE MAJEURE. If Operator is delayed, limited or unable to perform its obligations under this Agreement due to a Force Majeure Event, Operator shall promptly notify Owner of the occurrence of such Force Majeure Event. Operator shall be relieved from its obligations under this Agreement, when and to the extent Operator’s inability or failure to perform its obligations is caused by a Force Majeure Event, provided that the relief from performance is of no greater scope and of no longer duration than is required by such Force Majeure Event. Operator shall use all reasonable efforts to remedy its inability or failure to perform as a result of such Force Majeure Event and to mitigate the consequences of any such Force Majeure Event. Operator shall advise Owner of its effort to remedy its inability to perform caused by, and to mitigate the consequences of, any such Force Majeure Event, and shall promptly notify Owner Representative and Administrator when it will be able to resume performance of its obligations under this Agreement.

14.                               BOOKS AND RECORDS. Operator shall maintain on a current basis proper, accurate, detailed and complete books, records and accounts relating to the operation and maintenance of the Plant and the performance of the Work (collectively referred to as “Books and Records”), including all operating data and operating logs maintained pursuant to Section 3.3, which Books and Records shall remain the property of Owner. Operator shall ensure that such Books and Records are kept in a manner that enables them to be separated from Operator’s own corporate books and records of account. Throughout the Term, Owner shall have the right, upon three (3) Business Days’ prior written notice and during normal business hours, to inspect and review the Books and Records in the possession of Operator. Upon the expiration of the Term or the early termination of this Agreement, Operator shall transfer the possession of all Books and Records held by it to Owner.

15.                               TITLE; LIENS.

15.1                        Project Company Intellectual Property. The Operator hereby acknowledges and agrees that each Project Company shall hold free and clear title to all specialized equipment, tools, spare parts, Materials, reports, records, books, plans, designs, papers or print outs, or other information used by Operator exclusively in connection with the performance of the Work under this Agreement with respect to the Project held by such Project Company, including without limitation those which the Operator has generated or received (including from Service Providers) in the course of performing its duties hereunder, but excluding any Operator owned software or other intellectual property developed by Operator outside of the Work provided under this Agreement, and personnel records of Operator (collectively, the “Project Company Intellectual

20

Property”). Owner hereby agrees to cause each Project Company to grant to Operator a license to use the Project Company Intellectual Property in the performance of the Work under this Agreement. Such license shall automatically expire immediately upon the termination or expiration of this Agreement.

15.2                        Title to Project Company Intellectual Property and Materials. Title to any Materials and the license to use any Project Company Intellectual Property shall pass or be granted, as the case may be, directly from the provider or supplier thereof to Owner when purchased or acquired and shall be free and clear of all liens and encumbrances created or imposed by, through or under Operator. Operator shall keep and maintain the Plant free and clear of all liens and encumbrances resulting by, through or under Operator, other than liens and encumbrances which are being diligently contested in good faith and by appropriate proceedings; provided that Operator shall pay or discharge of record any such contested lien or encumbrance within such period of time so as to avoid a default by Owner or any Project Company under any applicable financing agreement (including the Financing Agreement and related documents) or Project Document, including by recording a bond to the extent permitted by and in accordance with applicable Law. Upon the failure of Operator to promptly discharge or cause to be released any such lien or encumbrance subject to this Section 15.2, Owner (or the applicable Project Company) may, but shall not be obligated to, pay, discharge or obtain a surety bond for such lien or encumbrance and, upon such payment, discharge or posting of surety bond therefore, shall be entitled to immediately recover from Operator the amount thereof together with all expenses incurred by Owner (or such Project Company) in connection with such payment, discharge or posting, or set off all such amounts against any Compensation owed by Owner to Operator. Notwithstanding the foregoing, Operator shall not be responsible for preventing liens and encumbrances that result from Owner’s failure to timely pay amounts owing to Operator under this Agreement.

16.                               EVENTS OF DEFAULT.

16.1                        Operator Defaults. The occurrence of any one or more of the following events shall constitute an event of default by Operator hereunder (an “Operator Event of Default”):

16.1.1 Operator fails to pay to Owner any payment required under this Agreement that is not in dispute, and such failure continues for thirty (30) days after receipt of written notice of such failure;

16.1.2 Except as otherwise expressly addressed in this Section 16.1, Operator is in material breach of its obligations under this Agreement and such material breach continues uncured for thirty (30) days after receipt of written notice from Owner;

16.1.3 Operator voluntarily commences or acquiesces to bankruptcy, insolvency, reorganization, stay, moratorium or similar debtor-relief proceedings, or shall have become insolvent or generally does not pay its debts as they become due, or admits in writing its inability to pay its debts, or makes an assignment for the benefit of creditors; or

21

16.1.4 Insolvency, receivership, reorganization, bankruptcy, or similar proceedings shall have been commenced against Operator and such proceedings remain undismissed or unstayed for a period of sixty (60) days.

16.2                        Owner Defaults. The occurrence of any one or more of the following events shall constitute an event of default by Owner hereunder (an “Owner Event of Default”):

16.2.1 Owner fails to pay to Operator any payment required under this Agreement that is not in dispute, and such failure continues for thirty (30) days after receipt of written notice of such failure;

16.2.2 Except as otherwise expressly addressed in this Section 16.2, Owner is in material breach of its obligations under this Agreement and such material breach continues uncured for thirty (30) days after receipt of written notice from Operator;

16.2.3 Owner voluntarily commences or acquiesces to bankruptcy, insolvency, reorganization, stay, moratorium or similar debtor-relief proceedings, or shall have become insolvent or generally does not pay its debts as they become due, or admits in writing its inability to pay its debts, or makes an assignment for the benefit of creditors; or

16.2.4 Insolvency, receivership, reorganization, bankruptcy, or a similar proceeding shall have been commenced against Owner and such proceeding remains undismissed or unstayed for a period of sixty (60) days.

16.3                        Financing Party Cure Rights. Operator’s right to exercise the option to terminate this Agreement pursuant to Section 2.2 is subject to Operator first delivering to the Financing Parties, simultaneously with delivery thereof to Owner, written notice of Owner’s failure to cure the default and Operator’s intent to terminate as a result thereof. Each Financing Party shall have the option to cure such Owner Event of Default within thirty (30) days after the cure period otherwise provided in Section 16.2 or such additional period as may reasonably be required or to cause the Financing Parties’ designee to assume this Agreement but in no event to exceed ninety (90) days; provided, however, that the Owner Event of Default described in Section 16.2.1 shall only be curable within thirty (30) days from the receipt by the Financing Parties of such notice to cure such payment default. In any such case, Operator’s right to terminate this Agreement shall be of no further force and effect upon the cure by the Financing Parties of such default. If the Financing Parties desire to cause their designee to assume all rights and obligations of this Agreement, they shall provide written notice to that effect within the cure period permitted by this Section 16.3.

16.4                        Event of Default Remedies. Without limiting the provisions of Sections 9.2, 10 and 11, the sole and exclusive remedy of each Party upon the occurrence and continuation of an Event of Default by the other Party is the termination of this Agreement and payment of the amounts required to be paid under and in accordance with Section 2.2 and, if applicable, such Sections 9.2, 10 and 11.

22

17.                               ASSIGNMENT.

17.1                        Assignment. This Agreement shall be binding upon and shall inure to the benefit of the successors and permitted assigns of Owner and Operator. Without the prior written notice to or consent of Operator, this Agreement may be assigned by Owner to Financing Parties (in their capacities as Financing Parties) and such Financing Parties may further assign such rights or obligations. The rights and obligations of Owner under this Agreement with respect to any Project may be assigned without the consent of Operator to the Project Company for such Project, and, upon the request of Owner, Operator shall enter into a separate agreement with respect to the Work related to such Project with such Project Company on the same terms and conditions as set forth in this Agreement, and upon the entry into and effectiveness of such separate agreement, the rights and obligations of Owner and Operator with respect to such Project under this Agreement shall terminate as provided in such separate agreement. Except as expressly provided in this Section 17.1, neither Party may assign or transfer this Agreement, in whole or in part, except upon the prior written consent of the other Party hereto, which consent shall not be unreasonably withheld.

17.2                        Financing Cooperation; Subordination Agreement. Operator shall execute and deliver such consent forms, acknowledgments and other documents and deliver such legal opinions of counsel to Operator as are reasonably requested by Owner or reasonably required by a Financing Party to effect and/or to evidence a collateral assignment by Owner of this Agreement to such Financing Party. Upon the request of the Financing Parties under the Financing Agreement, Operator agrees to deliver a subordination agreement in favor of such Financing Parties pursuant to which Operator agrees that any fee or payment (other than reimbursements for documented expenses to the extent contemplated hereunder) made to Operator by Owner in excess of such fee or payment set forth in the “Base Case Model” or the “Schedule and Budget” set forth in the Financing Agreement, shall be subordinated to the obligations of Owner to the Financing Parties under such Financing Agreement, which subordination agreement shall be in form and substance substantially similar to the Subordination Agreement (as defined in the Financing Agreement).

In the event that any of the terms, covenants or conditions hereof or the application thereof to either Party or any circumstance shall be held by a court of competent jurisdiction to be invalid in any

23

jurisdiction, the remaining terms, covenants and conditions hereof and the application thereof to either Party or any other circumstance, or in any other jurisdiction, shall not be affected thereby.

18.3                        Confidentiality. Each Party agrees that it shall not disclose (and shall cause its directors, officers, attorneys, employees and agents not to disclose), without the prior consent of the other Party, any information with respect to such other Party that is furnished pursuant to this Agreement or learned during the course of performance of the Work, including any information that would constitute confidential information under the terms of any Project Document (“Confidential Information”), provided that any Party may disclose, or allow the disclosure of, any Confidential Information (a) to its directors, officers, attorneys, employees, agents, auditors, professional advisors, consultants and lenders as necessary to perform a Party’s obligations under this Agreement, (b) as has become generally available to the public other than as a result of breach of this Section 18.3, (c) as may be required or appropriate in any report, statement or testimony submitted to any Governmental Authority having or claiming to have jurisdiction over such disclosing Party; provided, however, that to the extent such Confidential Information may be excluded from any such report, statement or testimony, or may be submitted subject to administrative confidentiality protection, in each case without prejudicing in any manner the position of the potentially disclosing Party, such Party shall exclude the information or submit it subject to confidentiality protection, (d) which was otherwise known by the receiving Party prior to disclosure or is disclosed to the receiving Party by a third party not in violation of any duty of confidentiality, other than, in each case, from a source other than an Affiliate of Owner, (e) as may be required or appropriate in response to any summons or subpoena from a Governmental Authority or in connection with any litigation, or (f) to comply with any Permit or applicable Law. Confidential Information shall not be deemed to include information acquired by or disclosed to Operator’s employees who may be transferred to other facilities operated by Operator, provided such information is limited to general knowledge useful to allow such employees to better perform their work at such other facilities and does not include commercially sensitive or Plant-specific operating data. The Parties’ obligations under this Section 18.3 shall expire two (2) years after the expiration or termination of this Agreement. Upon expiration or termination of this Agreement, all written or other tangible Confidential Information held by a Party shall, if requested by the Party who owns such Confidential Information, be returned to such owning Party. Notwithstanding anything to the contrary set forth in this Agreement, Operator agrees to abide by the terms and conditions of the confidentiality undertakings of Owner or any Project Company set forth in any of the Project Documents.

18.4                        Public Release of Information. Neither Operator nor Owner shall issue a press release or make a statement intended for release to the general public with respect to the transactions contemplated by this Agreement, including the terms and conditions hereof, without the consent of the other Party, unless the Party desiring to make a statement or press release is advised by legal counsel that such statement or press release is mandated by a Permit or Law (in which case the Party making the statement or press release shall notify the other Party in advance of such statement or press release).

18.5                        Headings. Captions and paragraph headings used herein are for convenience only and are not a part of this Agreement and shall not be used in construing it.

18.6                        Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the Parties and their respective successors and permitted assigns.

18.7                        Governing Law; Dispute Resolution.

18.7.1 This Agreement, and the rights and obligations of the Parties and any dispute arising under or relating thereto (whether in contract, tort or otherwise) shall be governed by and construed in accordance with the laws of the State of New York, without giving effect to the conflict of law rules thereof (other than Sections 5-1401 and 5-1402 of the New York General Obligations Law) or any other statute or doctrine that might call for the application of the laws of any other jurisdiction.

18.7.2 The Parties shall attempt, in good faith, to resolve or cure all disputes (including disputes with respect to claimed Events of Default) by mutual agreement in accordance with this Section 18.7 before initiating any legal action or attempting to enforce any rights or remedies hereunder (including termination), at law or in equity (regardless of whether this Section 18.7 is referenced in the provision of this Agreement which is the basis for any such dispute). If there is a dispute as to whether an Event of Default has occurred or if any other dispute under this Agreement has arisen, either Party may give notice thereof to the other Party which notice shall describe in reasonable detail the basis and specifics of the alleged Event of Default or dispute. Within five (5) days after delivery of such notice, the designated representatives of both Parties shall meet to discuss and attempt to resolve or cure such dispute or claimed Event of Default. If such representatives are unable to resolve the dispute or claimed Event of Default within fifteen (15) days after delivery of such notice, the matter shall be referred to a senior officer of the Operator and a senior officer of the Owner. If such Senior Officers are unable to agree on an appropriate cure or resolution within ten (10) days after the matter has been referred to them, either Party may inform in writing the other Party thereof and the Parties may have recourse to mediation, arbitration, or other alternative dispute resolution device of their mutual selection. If the Parties cannot agree on an alternative dispute resolution device, each Party may pursue its legal remedies.

18.7.3 Pending final resolution of any dispute, the Parties shall continue to fulfill their respective obligations under this Agreement; provided, however, that the Owner may withhold any amount which is the subject of dispute from any payment otherwise due hereunder during the pendency of any dispute resolution proceeding. If the Operator prevails in such dispute, the Owner shall immediately pay to the Operator the unpaid amount in dispute with interest thereon, which interest shall accrue, at the rate specified in Section 8.5, for each day from and including the date on which such amount was originally due to, but excluding, the date of actual payment thereof.

18.8                        Entire Agreement. This Agreement (including the Exhibits hereto) contains the entire understanding between the Parties concerning the subject matter hereof and, except as expressly provided herein, supersedes all prior understandings and agreements, whether oral or

25

written, between the Parties with respect to the subject matter hereof. This Agreement may be amended, supplemented or modified only by an agreement in writing signed by each Party.

18.9                       No Partnership Created. Operator is an independent contractor with respect to the performance of its obligations hereunder. Neither the Operator nor any of its Affiliates, employees, subcontractors, vendors or suppliers, or any of their respective employees, shall be deemed to be agents, representatives, employees or servants of Owner or a Project Company as a result of this Agreement or of performing any duties hereunder, and no such Person as a result of entering into this Agreement or of performing any duties hereunder shall have the right, authority, obligation or duty to assume, create or incur any liability or obligation, express or implied, against, in the name or, or on behalf of Owner or a Project Company; provided that Operator shall have the right to act for and on behalf of Owner or a Project Company to the extent expressly contemplated by and in accordance with this Agreement. In no case shall this Agreement be construed to create any relationship whatsoever including employer/employee, partners or joint venture parties, between Owner or any Project Company, on the one hand, and Operator or any of its Affiliates, employees, subcontractors, vendors or suppliers, or any of their respective employees, on the other hand, or between Owner and any Project Company.

18.10                 No Third Party Rights. Except with respect to the Project Companies and indemnities set forth in Sections 9.2 and 10, the Parties do not intend to create rights in, or grant remedies to, any third party as a beneficiary of this Agreement or of any duty, covenant, obligation or understanding established under this Agreement.

18.11                 Representations and Warranties. Each Party hereby represents and warrants to the other Party as of the date of this Agreement that:

18.11.1 Such Party is duly organized, validly existing and in good standing under the laws of the jurisdiction of its formation and has all requisite power and authority to execute, deliver and perform its obligations under this Agreement;

18.11.3 All government approvals necessary for the execution, delivery and performance by such Party of its obligations under this Agreement have been obtained and are in full force and effect, except for those governmental approvals to be obtained by such Party in the course of performance of its obligations under this Agreement; and

18.11.4 This Agreement is the legal, valid and binding obligation of such Party, enforceable against such Party in accordance with its terms except as enforceability may be limited by bankruptcy, reorganization, insolvency, moratorium and other laws affecting creditors’ rights in general and except to the extent that the availability of

26

equitable remedies is subject to the discretion of the court before which any proceeding therefor may be brought.
