3.5                               Operator to Act as Independent Contractor.

(a)                       In performing the Services, Operator is acting and shall be deemed for all purposes to be an independent contractor. Owner and Operator are not partners, agents or joint venturers with each other, and this Agreement is not intended to nor shall it be construed to create a partnership or joint venture between Owner and Operator.

are deemed a “temporary employee” when such term is used to define ineligibility in benefits in any Owner employee benefit plan or program.

(6)                                 make, enter into, execute, amend, modify or supplement any Project Document or any other contract or agreement on behalf or in the name of Owner, or otherwise engage in any other transaction on behalf or in the name of Owner that is not expressly permitted under this Agreement.

If Prudent Utility Practices require otherwise, Operator shall notify Owner as soon as it becomes aware of any such conflict or inconsistency and provide Owner with a recommended means of resolving the conflict or inconsistency. As soon as practicable following delivery to Operator of any Additional Agreement, Operator will be fully aware of and in performing the Services shall fully comply with all the terms and conditions of such Additional Agreements that are applicable to the operation and maintenance of the Project, except to the extent required by Prudent Utility Practices; provided, however, that Operator will be entitled to an equitable adjustment of the Budgets, if appropriate to account for any impact on Operator’s cost of providing the Services as a result of any such Additional Agreements. If Prudent Utility Practices conflict or are

inconsistent with the terms of an Additional Agreement, Operator shall notify Owner as soon as it becomes aware of the conflict or inconsistency and provide Owner with a recommended means of resolving the conflict or inconsistency. This Section 3.6(a) shall not be deemed to make Operator a party to any Project Document, Project Related Document or Additional Agreement.

Operator and Owner shall each select individuals who shall have the written authority to sign checks against or authorize withdrawals from the Owner’s Operating Account. All Taxes imposed upon or levied against any accrued interest or return on investment, in each case with respect to the funds in the Owner’s Operating Account, shall be for the account of Owner. Each month, no later than the date set forth in Section 4.2 and subject to Section 4.5, Owner shall pay by electronic funds transfer to the Owner’s Operating Account the undisputed amount set forth in the invoice delivered to it by Operator pursuant to Section 4.2 for such Billing Period, which amount, while in the Owner’s Operating Account, shall be managed by Owner for Owner’s benefit and invested at Owner’s sole risk of loss. Owner shall maintain a balance in the Owner’s Operating Account that equals the sum of unpaid Mobilization Compensation or Commercial Operation Compensation, as the case may be, with respect to such Billing Period plus the Contingency. If at any time the balance in the Owner’s Operating Account is less than such sum, Operator promptly shall notify Owner. Upon receipt of a Notice of such a shortfall in funds and an invoice with respect thereto, Owner shall pay by electronic funds transfer the amount of such shortfall to the Owner’s Operating Account; during the Mobilization Phase, within 15 Business Days, and during the Commercial Operation Phase, within 5 Business Days of receipt of such Notice and invoice, in either case to the extent permitted by the Financing Documents.

(c)                 Operator shall not be under any obligation to use its own funds to pay any Mobilization Compensation or Commercial Operation Compensation, and shall have no liability for, but shall be indemnified by Owner, beginning on the Effective Date, for, amounts payable as Mobilization Compensation or Commercial Operation Compensation that are not paid as a result of Owner’s failure to provide funds in accordance with this Section 4.3. Operator may use the funds in the Owner’s Operating Accounts only for the purpose of making payments for Mobilization Compensation and Commercial Operation Compensation as they become due and payable, to the extent such payment expressly is not otherwise restricted by limits on Operator’s authority as set forth herein.

(d)                If it is determined, through an audit conducted pursuant to Section 6.7 or otherwise, that funds in the Owner’s Operating Account or other Owner funds were used by Operator other than for making payments for Mobilization Costs, Operating Expenses, Fixed Labor Expenses or Allocated O&M Costs, Operator shall reimburse Owner for the amount of such improper payments, plus interest to accrue from day to day at the Default Rate from, and including, the date such improper payment was made until, but excluding the day upon which the amount due actually is received by Owner. If Operator receives a payment for the account of Owner that is not a payment to Operator for its own account by Owner, it shall pay that amount into an account to be nominated by Owner, duly endorsed and without recourse in the form received.

4.4                               Cash Neutral.

(a)                       Notwithstanding any provision in this Article 4 to the contrary, all payments to be made by Owner under this Article 4 are due and are to be received by Operator in advance of Operator’s incurrence of any expense to which such payments from Owner are to be applied.

4.5                               Interest and Disputed Items.

(a)                       Any amount properly due and payable to a Party pursuant to this Agreement and remaining unpaid after the date when the payment was due shall bear interest thereafter; such interest to accrue from day to day at the Default Rate from, and including, the date such amount is due until, but excluding the day upon which the amount due actually is received.

(b)                       If any item or part of an item of a Billing Report or statement rendered by a Party is disputed by the recipient in good faith, the Parties shall use all reasonable efforts to resolve the dispute as soon as practicable, but the disputing Party shall pay all undisputed amounts in accordance with this Article 4. If the dispute, or any portion thereof, is resolved against the disputing Party, such Party shall within 10 Business Days of the date of such resolution pay the other Party an amount

corresponding to such portion of the dispute that has been resolved against the disputing Party, plus interest on such amount in accordance with Section 4.5(a).

All Mobilization Costs, Operating Expenses and Allocated O&M Costs shall include a provision for associated Taxes other than Operator Taxes, as described in Section 3.16, and Operator shall pay such associated Taxes (other than Operator Taxes) with funds made available by Owner. Owner may pay any Tax borne by it hereunder directly to the appropriate Competent Authority unless it is required to be paid directly by Operator.

4.7                               Due Date Adjustment. If the due date for payment of any amount hereunder falls on a day that is not a Business Day, then the due date shall be the Business Day immediately following such date.

Notwithstanding (i) any dispute, controversy or claim that Operator may have against or related to Owner, the Project, the Services or this Agreement, and regardless of the basis for such dispute, controversy or claim or (ii) the failure of Owner to approve a proposed Plan or a Budget pursuant to Section 6.1 or Section 6.2, Operator shall continue to perform the Services and its other obligations hereunder in accordance with the terms of this Agreement, so long as Owner continues to pay Operator for all Services not subject to a Dispute, unless otherwise directed by the Management Committee.

(c)                        Within 30 days of the Management Committee’s receipt of the proposed Annual Budget and Annual Operating Plan, the Management Committee shall approve or disapprove such proposed Budget and Plan, such approval not to be unreasonably withheld. If the Management Committee disapproves of a proposed Annual Budget or Annual Operating Plan, the Management Committee shall provide detailed reasons for such disapproval. The Parties shall be obligated to meet and attempt in good faith to reach agreement on an approved Annual Budget or Annual Operating Plan.

6.3                               Expected Budget Overruns. If, at any time during the performance of the Services Operator reasonably anticipates that the aggregate costs of providing the Services may exceed the amount of Budgeted Expenses set forth in the applicable Budget, Operator shall promptly advise the Management Committee of such situation by Notice and, pursuant to Section 6.4, propose for the Management Committee’s approval any changes to the applicable Budget that Operator considers may be necessary.

6.4                               Changes and Revisions to Budgets and Plans.

(a)                       The Management Committee may specify from time to time, in consultation with Operator and upon reasonable prior Notice, changes to be made to any Budget or Plan, including changes to the format and level of detail record, for any such Budget or Plan. The relevant changes shall be adopted by Operator effective the date that the revisions are agreed, and shall be applied to the first month following such agreement.

(b)                       The Management Committee may also request Operator to update any Budget or Plan as may be appropriate to reflect changes in assumptions made in their preparation that are desirable in the light of the performance of the Project or any other material change in circumstance or in the assumption used to develop such Budget or Plan. These updates shall be submitted to the Management Committee for its approval.

6.5                               Budget and Plan Disputes. If there is any dispute between Operator and the Management Committee as to the form or content of any Budget or Plan that the Parties fail to resolve, then:

(a)                       If the Parties are unable to agree on an approved Plan or Budget for any Operating Year at least 60 days prior to the commencement of such Operating Year, the Parties shall revert, on a temporary basis, to the Plan or Budget from the previous Operating Year, as adjusted by the CPI Index to adjust for any changes in the prices of goods and services used by Operator in performing Services

under this Agreement, to allow Operator to continue to provide those Services for the current Operating Year and until such time that the proposed Budget or Plan for the current Operating Year is approved; and

(b)                                 To the extent the Management Committee’s failure to approve the relevant Plan or Budget, or any revision or change thereto, has an adverse effect on Operator’s ability to perform the Services in accordance with this Agreement, Operator shall not be held in breach of this Agreement and shall not be liable to Owner or any Competent Authority as a consequence thereof, provided that Operator uses reasonable good faith efforts to comply with the requirements of this Agreement notwithstanding the Management Committee’s failure to approve the Plan or Budget.

6.6                               Five-Year Forecast. In conjunction with, but separate from, the preparation of the Annual Operating Plan and the Annual Budget for each Operating Year, and based on the dispatch forecast provided by Owner pursuant to Section 5.8, Operator shall prepare for the then current year of the Agreement and projecting forward for an additional five years, an operation and maintenance plan and cost forecast, including major maintenance and capital repairs, and recommended capital improvements, in form and substance consistent with the Agreed Procedures and the O&M Manuals or as the Management Committee reasonably may require (the “Five-Year Forecast”). Operator shall submit each Five-Year Forecast to the Management Committee at the time of submission of each Annual Operating Plan and Annual Budget under Section 6.2(c).

6.7                               Books and Records.

(a)                                 Operator shall maintain on a current basis proper, accurate, detailed and complete books, records and accounts relating to the operation and maintenance of the Project and the performance of the Services (collectively referred to as “Books and Records”), including all operating data and operating logs maintained pursuant to Section 3.1, and as necessary to verify the incurring and payment of all capital and operating expenditures and Operator’s performance of the Services. All Books and Records referred to in this Section 6.7 shall be established and maintained in accordance with GAAP and shall be in a format sufficient to permit the verification referred to in the preceding sentence. 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.

(b)                                 Throughout the Term and for a period of five years following the end of the Term, Owner and its Representatives shall have the right, upon three Business Days prior Notice and during normal business hours, to inspect and audit the Books and Records that Operator is required to maintain under this Section 6.7.

(c)                                  Operator shall maintain all Books and Records for a period of six years following the creation thereof or as required by applicable Law, and such Books and Records shall not thereafter be destroyed unless (1) Operator provides not less than 30 days prior Notice to Owner, and (2) within such 30-day period Owner does not request retention of such Books and Records. In the event of a termination or cancellation of this Agreement, or upon the expiration of the term of this Agreement, Operator will leave all such Books and Records at the Project site or deliver the same to Owner.

7.2                               Disclosure of Claims.

(a)                       Each Party shall promptly furnish the other Party with information relating to the operation and maintenance of the Project to enable the first Party to comply with its disclosure obligations under the insurance policies that it has procured.

(b)                       Each Party shall promptly notify the other Party of any claim with respect to any of the insurance policies referred to in Section 7.1, as applicable, accompanied by reasonable details of the incident giving rise to such claim.

(a)                       If Operator fails to effect or maintain insurance pursuant to Section 7.1, Owner may, after giving Operator 10 days’ prior Notice of its intention to do so, effect and maintain the insurance. The premium paid by Owner may be off-set against any amount set forth in the applicable Budget for insurance. Owner shall have the right to back-charge Operator for the expenses related to the procurement of the All-Risk Property Insurance, Marine Cargo/Ocean Cargo Insurance, and the Casualty coverages noted in Schedule 7.1.1.A., but not for the premium costs related to such insurance(s). Owner shall have the right to back charge for the cost of procuring and maintaining the insurance coverages noted in Schedule 7.1.1.B., including the premium cost of such insurance.

(b)                       If Operator receives the proceeds of any insurance with respect to any of Owner’s property, it shall hold such proceeds in trust for the benefit of Owner and shall comply with any requirements of Owner regarding the application or distribution of such proceeds.

(c)                        Nothwithstanding (b) above, the Operator agrees to maintain insurance in accordance with the requirements of any financing documentation and to ensure compliance with any required Lenders endorsements and mortgagee loss payable clauses.

ARTICLE 8. INDEMNITY AND LIABILITY

8.1                               Operator’s Liability. Notwithstanding anything to the contrary in this Agreement, except (a) in cases of actual fraud by Operator or Operator’s willful and intentional failure to perform the Services in breach of this Agreement or (b) with respect to damages claimed by third parties for which Owner is entitled to indemnification from Operator pursuant to Section 8.2, Operator’s total liability, whether based in contract, warranty, tort, strict liability or otherwise, arising out of, connected with or resulting from this Agreement or from the performance or breach hereof, or from any Services covered by or furnished by the Operator, shall be limited to $500,000 per Operating Year as of the Effective Date of this Agreement, subject to an annual escalation based on the CPI Index each successive Operating Year. It is expressly understood

and agreed that the liability limitation expressed in this Section 8.1 is separate from, and is not to be construed as limiting, the limits of insurance and coverage described in Article 7.

8.2                               Indemnities.

(a)                       Operator shall indemnify, defend and hold harmless Owner, its Affiliates and their respective successors, assigns, shareholders, members, officers, directors, managers, employees, agents, servants and any subcontractors from and against any and all liabilities to third parties arising as a result of the negligence, willful misconduct or breach of this Agreement by Operator or any employee, agent, servant, Subcontractor or consultant of Operator or anyone directly or indirectly employed by them or for whose acts they may be liable. Any indemnification payable with respect to a claim by Owner hereunder shall be net of any insurance proceeds actually paid to Owner under Owner’s or Operator’s insurance policies with respect to the circumstances giving rise to Operator’s indemnification of Owner hereunder.

(b)                       Owner shall indemnify, defend and hold harmless Operator, its Affiliates and their respective successors, assigns, shareholders, members, officers, directors, managers, employees, agents, servants and any subcontractors from and against liabilities to third parties arising as a result of the negligence, willful misconduct or breach of this Agreement by Owner, provided that Owner’s breach of this Agreement was not caused by the actions or omissions of Operator or any of its Affiliates where Operator or any of its Affiliates had a duty to act. Any indemnification payable with respect to a claim by Operator hereunder shall be net of any insurance proceeds actually paid to Operator under Operator’s or Owner’s insurance policies with respect to the circumstances giving rise to Owner’s indemnification of Operator hereunder.

8.3                               Cooperation Regarding Claims.

(a)                       If any Party (in such capacity, an “Indemnified Party”) receives notice or has knowledge of any Loss that may result in a claim for indemnification by such Indemnified Party against the other Party (in such capacity, an “Indemnifying Party”) pursuant to this Article 8, such Indemnified Party shall promptly give the Indemnifying Party Notice of such Loss, including a reasonably detailed description of the facts and circumstances relating to such Loss, and a complete copy of all notices, pleadings and other papers related thereto, and in reasonable detail the basis for its potential claim for indemnification with respect thereto; provided, however, that failure to promptly give such Notice or to provide such information and documents to the Indemnifying Party shall not relieve the Indemnifying Party from the obligation hereunder to respond to or to defend the Indemnified Party against such Loss except to the extent (and only to the extent) such failure shall materially diminish the ability of the Indemnifying Party to respond to such claim or to defend the Indemnified Party.

(b)                       The Indemnifying Party, upon its acknowledgement in writing of its obligation to indemnify the Indemnified Party, shall be entitled to assume the defense or to represent the interests of the Indemnified Party, which shall include the right to select and direct legal counsel and other consultants, appear in proceedings on behalf of the Indemnified Party and to propose, accept or reject offers of settlement, subject to 8.3(c) below, all at its sole cost; provided, however, that if any such action is reasonably likely to involve injunctive, equitable or prospective relief or materially and adversely to affect the Indemnified Party’s business or operations other than as a result of money damages or other money payments, then the Indemnified Party shall be entitled to take control of the

defense and investigation of such Loss, to employ and engage legal counsel and other consultants of its own choice to handle and defend the same, all at the sole cost and expense of the Indemnifying Party. Nothing herein shall prevent an Indemnified Party from retaining its own legal counsel and other consultants and participating in its own defense at its own cost and expense.

(c)                        If the Indemnifying Party assumes the defense or represents the interests of the Indemnified Party, no settlement shall be made without the consent of the Indemnified Party, which consent shall not be unreasonably withheld, conditioned or delayed. If the Indemnified Party assumes the defense of or represents its own interests, no settlement involving the payment of damages shall be made without the consent of the Indemnifying Party, which consent shall not be unreasonably withheld, conditioned or delayed, except that if the Loss is settled without the Indemnifying Party’s consent, the Indemnified Party shall be deemed to have waived all rights hereunder against the Indemnifying Party for indemnification arising out of such Loss.

(d)                       The Parties shall cooperate with each other in any notifications to insurers.

(e)                        Nothing herein shall be construed so as to relieve any insurer of its obligations to pay any Loss in accordance with the terms and provisions of a valid and collectible insurance policy insuring the subject matter or event that is a basis for such loss.

8.4                               Environmental Liability.

(a)                       Owner Liability. In no event shall Operator be responsible for present or future Environmental Claims 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 Project or adjacent areas, except as otherwise provided in Section 8.4(b). Without limiting the foregoing, Owner shall defend, indemnify and hold Operator harmless against, and shall reimburse Operator for such Environmental Claims.

(b)                       Operator Liability.

(1)                                 Except with respect to the releases set forth in Section 8.4(b)(3), in no event shall Owner be responsible for present or future Environmental Claims finally determined by a court of competent jurisdiction to have directly or indirectly related to or arisen out of bad faith, gross negligence, willful misconduct, or knowing and material non-compliance with Law (unless such non-compliance was engaged in at the express direction of the Owner), with respect to the existence, generation, use, collection, treatment, storage, transportation, recovery, removal, discharge or disposal of Hazardous Material at the Project or adjacent areas by Operator in the performance or non-performance of the Services, and Operator shall defend, indemnify and hold Owner harmless against, and shall reimburse Owner for such Environmental Claims; provided, however, that nothing contained herein shall be construed as requiring Operator to take any corrective action with respect to any Hazardous Material in existence prior to the date hereof unless directed to do so by a Competent Authority, in which case the corrective actions so

undertaken shall be deemed an Environmental Claim pursuant to Section 8.4(a) unless Devon Power is responsible therefor in its capacity as Landlord under the Site Lease or in its capacity as Lessor under the Shared Facilities Agreement.

(2)                                 Operator shall, in compliance with all Laws, take reasonable steps to mitigate a release of Hazardous Materials upon discovery; take no action to exacerbate a pre-existing release or cause a further release; provide full cooperation, assistance and access to Persons authorized to undertake corrective action; comply with all land use controls and Laws; and take no action to impede the performance of any institutional controls adopted to manage a pre-existing release except that Operator’s actions shall not unreasonably interfere with Owner’s business activities and/or the Ancillary Easement Areas as permitted by the Site Lease.

(3)                                 Operator shall, at its own cost, promptly remove and otherwise fully remediate in compliance with and to the extent required by applicable Laws all releases of Hazardous Materials at the Project or adjacent areas (expressly including exacerbation of Hazardous Materials present at the Project or adjacent areas if and only to the extent the nature and exact location of such Hazardous Materials are known by the Operator) arising out of bad faith, gross negligence, willful misconduct, or knowing and material non-compliance with Laws (unless such non-compliance was engaged in at the express direction of the Owner) by Operator.

(4)                                 Nothing in this Agreement shall be deemed to limit in any way Devon Power’s obligations as Landlord under the Site Lease or as Lessor under the Shared Facilities Agreement.

8.5                               Waiver of Consequential Damages. The Parties expressly waive all claims for all consequential, incidental, indirect, punitive, or special damages arising out of or relating to this Agreement but only to the extent that such damages are not covered by the insurance each Party is required to provide and maintain under this Agreement. This waiver includes, but is not limited to, uninsured consequential damages incurred for losses of use, income, profit including anticipated profits arising directly from the ownership of the Project, the provision of the Services, financing, business and reputation, and loss of management or employee productivity or of the services of such persons. For purposes of this provision, damages claimed by third parties for which a Party is entitled to indemnification from the other Party hereto pursuant to Section 8.2 shall not be deemed consequential, incidental, indirect, punitive, or special in nature. This provision shall survive the termination of the Agreement.

9.5                               Cooperation Following Termination.

(a)                       Upon termination of this Agreement under this Article 9 or under Article 10, Owner has the right to specify a reasonable period, not to exceed six months from the Notice of termination as a period of transition (the “Termination Transition Period”), during which Operator shall fully cooperate with Owner and its Representatives in the appointment and training of a Person(s) (“Successor Operator”) to take over the operation and maintenance of the Project, and in the turnover of the operation and maintenance of the Project to the Successor Operator. Operator shall provide Owner and Successor Operator and their respective Representatives full access to the Project and all information, data and records relating thereto, and Operator shall comply with all reasonable requests by Owner or Successor Operator in connection with taking over the operation and maintenance duties, including the execution and delivery of documents and taking of other actions, in each case as shall be necessary to facilitate the orderly transition of duties from Operator to Successor Operator.

Operator will execute all documents as necessary and as requested by Owner to assign to and vest in Owner, or, at Owner’s sole discretion, Successor Operator, all rights, benefits, interests and title in connection with third party contracts, if any, Operator entered for the benefit of the Project (other than any master agreements that do not relate solely to the Project); provided, however, that Owner shall indemnify and hold harmless

Operator for all liabilities arising under such contracts caused by Owner’s performance thereunder following such assignment.

(b)              Upon the occurrence and during the continuance of an Owner Event of Default, Operator shall have the right, in its sole and absolute discretion, to do any or all of the following: (1) to terminate this Agreement by Notice to Owner pursuant to Section 9.2; and/or (2) to pursue any and all other remedies available at law or in equity, subject to the dispute resolution procedures set forth in Article 12 and the other limitations set forth in this Agreement.

ARTICLE 11. FORCE MAJEURE

11.1                        Force Majeure Event. Except for the obligations of each Party to make payments of amounts then due hereunder to the other Party, each Party is excused from performance and will not be considered to be in default in respect to any obligation hereunder if failure of performance is due to a Force Majeure Event. Neither Party will be relieved of any obligations under this Agreement solely because of increased costs or other adverse economic consequences that may be incurred through the performance of such obligations of the Parties. Nothing contained herein, however, shall be construed to require either Party to prevent or settle a strike or other labor disturbance against its will.

11.2                        Effect of Force Majeure. Except as provided in Section 11.3, either Party shall be excused from performance and shall not be construed to be in default in respect of any obligation hereunder for so long as failure to perform such obligation shall be due to a Force Majeure Event. Such excuse from performance shall be of no greater scope and of no longer duration than is reasonably required by such Force Majeure Event.

11.3                        Certain Delays Not Excused. Notwithstanding that a Force Majeure Event otherwise exists, the provisions of this Article 11 shall not excuse:

(a)                       late payment of money;

(b)                       late delivery of equipment or materials caused by negligent acts or omissions on the part of Operator;

(c)                        late performance by Operator caused by Operator’s failure to engage qualified Subcontractors and suppliers or to hire an adequate number of personnel or labor; or

(d)                       delays resulting from reasonably foreseeable unfavorable weather or reasonably foreseeable unsuitable ground conditions or other similar reasonably foreseeable adverse conditions.

11.4                        Notice of Force Majeure. As soon as practicable and in any event within 48 hours following the commencement of Force Majeure Event, any Party desiring to invoke such Force Majeure Event as a cause for delay in the performance of any obligation that may be excused hereunder shall advise the other Party by Notice of such date and the nature and expected duration of such Force Majeure Event. As soon as practicable and in any event within three Business Days following the commencement of such Force Majeure Event, the Party having

invoked such Force Majeure Event as a cause for such delay shall submit to the other Party reasonable proof of the nature of such delay and its effect upon the time of performance. The Parties shall:

(a)                       make all reasonable efforts to prevent and reduce to a minimum and mitigate the effect of any delay occasioned by any Force Majeure Event including recourse to alternate acceptable sources of services, equipment and materials and construction equipment; and

(b)                       use their commercially reasonable efforts to ensure resumption of normal performance of this Agreement after the termination of any Force Majeure Event and shall perform their obligations to the maximum extent practicable and agreed between the Parties.

ARTICLE 12. DISPUTE RESOLUTION

12.1                        Settlement By Mutual Agreement.

(a)                       In the event any dispute, controversy or claim between or among Operator and Owner arises under, or is connected with or related in any way to, this Agreement or any right, duty or obligation arising hereunder (a “Dispute”), including a Dispute relating to the effectiveness, validity, interpretation, implementation, termination, cancellation or enforcement of this Agreement, the Parties shall first attempt in good faith to settle and resolve such Dispute by mutual agreement in accordance with the terms of this Section 12.1. In the event a Dispute arises, either Party may notify the other Party that it has elected to implement the procedures set forth in this Section 12.1 and shall deliver a written notice to that effect, signed by Plant Manager or Owner’s Management Representative, as the case may be, to the designated executive officers of the other Party. Within fifteen (15) Days after delivery of any such notice to the other Party, representatives of senior management of each of the Parties shall meet at a mutually agreed upon time and place to attempt, with diligence and good faith, to resolve and settle such Dispute.

(b)                       Should mutual resolution and settlement not be achieved at the meeting of representatives of senior management of each of the Parties held for such purposes as contemplated in Section 12.1(a), or should no such meeting take place within the fifteen (15)-Day period as contemplated in Section 12.1(a), as such period may be extended by mutual agreement, either Party may by notice to the other Party, submit the Dispute to binding arbitration in accordance with the provisions of Section 12.2 and Exhibit A. Upon the receipt of a notice of referral to arbitration hereunder, both of the Parties shall be compelled to arbitrate the Dispute in accordance with the terms of this Article 12 and Exhibit B.

12.2                        Arbitration. Each Party hereby agrees that any Dispute which is not resolved pursuant to the provisions of Section 12.1 may be submitted to binding arbitration hereunder in accordance with Section 12.1(b) and if so submitted shall be resolved exclusively and finally through such binding arbitration. This Article 12 and Exhibit A constitute a written agreement by the Parties to submit to arbitration any Dispute arising under or in connection with this Agreement within the meaning of the Federal Arbitration Act, 9 U.S.C. §§ 1, et seq.

12.3                        Emergency Relief. Without affecting the Parties’ agreement to arbitrate Disputes, either Party may seek injunctive relief or other form of emergency relief at any time from any state

court of competent jurisdiction in New Haven, Connecticut or the federal court for the District of Connecticut.

12.4                        Injunctive Relief. The arbitration panel shall have authority to order specific performance including interim injunctive relief prior to the Dispute being resolved. The arbitration panel shall have the authority to decide all issues concerning the fulfillment of any condition precedent to the arbitrability of a claim or defense, the amount of damages to be awarded, if any, and the arbitrability of the issues presented. The arbitration panel is not empowered to award damages in excess of compensatory damages such as punitive damages.

12.5                        Confidentiality. All Disputes resolved pursuant to this Article 12 shall be subject to the confidentiality provisions set forth in Article 14

12.6                        Survival. The provisions of this Article 12 shall survive the expiration or earlier termination of this Agreement.
