In the event of a change in law, regulation or other legal requirement after the date of this Contract which materially decreases Seller's costs of providing service to Purchaser, Seller shall adjust the Demand Charge and/or the Energy Charge in a reasonable manner to pass through to Purchaser 25% of the benefits of any cost reduction resulting from such change. 20. Taxes Purchaser shall pay any and all sales taxes, gross receipts taxes, excise taxes, franchise fees or any other fees or charges, including, without limitation, any BTU tax or carbon tax, imposed by any federal, state or local government or any regulatory agency over the provision of service hereunder or Canal Unit 1 (including without limitation any tax imposed on NEPOOL Defined Products produced by Canal Unit I or any tax imposed on interconnection services) with the exception of income taxes or property taxes. Seller represents and warrants that as of the date hereof it is not aware of any such taxes, fees or charges which are imposed by any governmental authority and which would be payable by Purchaser in accordance with this Section 20. 21. Interpretation The interpretation and performance of this Contract shall be in accordance with and controlled by the law of the Commonwealth of Massachusetts. 22. Regulation This Contract, and all rights, obligations and performance of the Parties hereunder, are subject to all present and future applicable federal, state and local laws and to all present and future duly issued and promulgated orders, regulations, requirements and other duly authorized action of any governmental authority having jurisdiction in the premises. 23. Dispute Resolution (a) In case of any dispute between the Parties and after notice of such dispute has been delivered from one Party to the other Party, such dispute shall be referred to the Contract Purchasers Committee for resolution. If the Contract Purchasers Committee fails to resolve the dispute in a manner satisfactory to each Party within 30 days after notice of said dispute is received by a Party, either Party may submit the matter to a Senior Officers Committee composed of the Presidents or other senior officers of each Party. Each Contract Party shall designate a senior officer to serve on the Senior Officers Committee for the purpose of resolving the dispute. If the Senior Officers Committee fails to resolve the dispute within 15 days following the submission of the dispute to said committee, either Party may give the other Party notice (a "Mediation Notice") that the dispute shall be referred to mediation in accordance with Section 23(b). If the dispute between the Parties involves one o r more of the Other Purchasers, each of the Other Purchasers shall have the rights of the Parties under this Section 23(a). (b) If either Party delivers a Mediation Notice to the other Party, the Parties shall participate in a non-binding dispute resolution procedure whereby each Party presents its case at a hearing (the "Hearing") before a neutral mediator approved by each Party. If the Parties fall to agree upon the mediator within seven (7) days after the date of the Mediation Notice, either Party may direct the American Arbitration Association to select the mediator. Each Party may be represented at the Hearing by lawyers. If the mediation proceedings do not result in a resolution of the dispute, such mediation proceedings shall be without prejudice to the legal position of either Party. The Parties shall each bear their respective costs incurred in connection with this procedure, except that the fees and expenses of the neutral mediator and the costs of the facility for the Hearing shall be allocated in the amount of fifty percent (50%) to each Party. If the dispute is not resolved pursuant to Section 23(a) or within twenty one (21) days after the date of the Mediation Notice, either Party may pursue any and all remedies and legal proceedings as are available. If the dispute between the Parties involves one or more of the Other Purchasers, each of the Other Purchasers shall have the rights of the Parties under this Section 23(b), and the fees and expenses of the neutral mediator and the costs of the facility for the Hearing shall be allocated equally among the Parties and the Other Purchasers involved in the dispute. (c) Nothing in this Section 23 shall limit the rights of either Party to seek in any court of competent jurisdiction such interim relief as may be needed to maintain the status quo, to prevent irreversible harm, or otherwise protect the subject matter of the mediation until the matter shall have been finally resolved; provided, however, any such interim relief ordered by a court shall not determine or prejudge the substantive issues to be decided by such mediation. (d) Notwithstanding anything to the contrary in this Section 23 or any other provision in this Contract, if Purchaser disputes an amount invoiced pursuant to Section 10 of this Contract, Purchaser shall pay the invoiced amount in full prior to invoking this Section 23, subject to later return with interest accrued in the interim at the Interest Rate. 24. Communications and Addresses Except as the Parties may otherwise agree, any notice, request, bill or other communication from one Party to the other, relating to this Contract or the rights, obligations or performance of the Parties hereunder, shall be in writing and shall be effective upon delivery to the other Party. Any notice, request, demand, or statement, which may be given to or made upon a Party hereto by the other Party hereto under any of the provisions of this Contract, shall be in writing unless it is specifically provided otherwise herein, and shall be treated as duly delivered either ( 1) when the same is delivered in person or by reliable courier service or (2) three (3) days after being deposited in the United States mail, by certified mail, postage prepaid, and properly addressed to the Party to be served at the addresses listed below the signature of such Party, or such other address as a Party may notify the other in accordance with this Section 24. 25. Amendments (a) Any amendments to this Contract shall be in writing. If the terms of any of the Other Purchasers' New Contracts, as amended from time to time, are different from the terms of this Contract, Seller shall give Purchaser the right to amend this Contract to the same or substantially similar terms to such Other Purchaser's New Contract. Purchaser shall notify Purchaser in writing within 15 days after Seller enters into any Other Purchaser's New Contract or any amendment thereto which contains different terms than the terms herein. Purchaser shall have 15 days after receipt of such notice to enter into an amendment of this Contract to contain such different terms. (b) Prior to Seller or its Affiliate accepting an assignment of any Other Purchaser's New Contract or Original Contract, Seller shall first issue a request for proposals (an "RFP") to Purchaser regarding the terms (other than price) under which Seller or its Affiliate is willing to accept such an assignment. The RFP shall allow Purchaser to submit an offer for the assignment of this Contract to Seller or its Affiliate, and such offer shall not be deemed to be nonconforming simply because this Contract contains different terms than an Other Purchaser's Original Contract or New Contract. If Purchaser submits a conforming offer, Seller or its Affiliate shall not accept an assignment from an Other Purchaser for a price that is less favorable to Seller than the offer submitted by Purchaser. Seller and its Affiliate shall not be under an obligation to accept any offer in response to the RFP, and if Seller or its Affiliate changes the terms under which it intends to accept an assignment of an Other Purchaser's Original Contract or New Contract, Seller shall reissue the RFP. (c) Seller's obligation under Section 25(b) shall terminate upon Purchaser's assignment of this Contract to a third party. 26. Assignment (a) Neither Party may assign this Contract without the written consent of the other Party except in accordance with this Section 26. (b) Upon not less than fifteen (15) days prior written notice to Purchaser, Seller may assign this Contract to any party which acquires Canal Unit I and which meets the Creditworthiness Criteria, provided, however, Purchaser shall not unreasonably withhold its consent if a proposed assignee is a direct or indirect subsidiary of an entity which meets the Creditworthiness Criteria. Seller may assign this Contract as security to its lenders and their agents. (c) Upon not less than fifteen (1 5) days prior written notice, Purchaser may assign this Contract to any party which meets the Creditworthiness Criteria provided, however, Seller shall not unreasonably withhold its consent if a proposed assignee is a direct or indirect subsidiary of an entity which meets the Creditworthiness Criteria. Purchaser may assign this Contract as security to its lenders and their agents. (d) Any other assignment of this Contract shall not operate to relieve the assigning Party of its obligations under this Contract without the written consent of the other Party. Each Party agrees to execute such consents as are reasonably requested by the other Party for an assignment to its lenders. 27. Default: Remedies; Limitation of Liability (a) As used herein, "Event of Default" shall mean, in relation to a Party (the "Defaulting Party"): (i) Purchaser as the Defaulting, Party fails to make any payment that is required hereunder to be made to Seller when due, and such failure continues for five (5) Business Days after written notice from Seller; (ii) Seller as the Defaulting Party breaches Section 4(a) by making deliveries of Purchaser's portion of NEPOOL Products from Canal Unit 1 to third parties; (iii) the Defaulting Party fails to perform any of its material obligations hereunder, other than as provided in subsection (i) or (ii), and such failure is not excused by force majeure and continues for sixty (60) days after the Defaulting Party receives written notice from the other Party (the "Non Defaulting Party") of such failure; provided, however, with respect to a failure to cure any such obligation, if a period in excess of sixty (60) days is required to cure such failure, the Defaulting Party shall have such additional amount of time, not to exceed one hundred eighty (I 80) days, as may be necessary to cure such failure provided that the Defaulting Party uses reasonable diligence to remedy such failure in accordance with Good Utility Practice; or (iv) the Defaulting Party makes an assignment or general arrangement for the benefit of creditors, files a petition in, or otherwise commences any proceedings in, bankruptcy or under similar law, or otherwise becomes bankrupt (however evidenced). (b) In the event Seller falls to deliver energy from Canal Unit I as a result of Seller's breach of its obligations under Section 18 which is not excused by Section 14, during any cure period provided in Section 27(a)(Iii) Purchaser shall be entitled to all remedies available under Section (c) except termination of this Contract. Purchaser shall give Seller prompt written notice whenever Purchaser believes that the provisions of this Section 27(b) are applicable. (c) Upon an Event of Default, the Non-Defaulting Party may resort to all remedies available at law or in equity, subject to the limitations set forth in Section 27(d). If it is necessary for any Party to institute legal proceedings or retain an attorney in attempting to collect a delinquent bill. the other Party shall pay any and all expenses and costs of collection, including reasonable attorneys' fees, incurred by such collecting Party. (d) Except as otherwise explicitly stated herein, in no event shall either Party be liable for punitive, exemplary, special, consequential or incidental damages arising from any breach or default under this Contract, or from any act or omission under or in connection with this Contract. Seller's rights to payment of the Demand Charge, Energy Charge and other amounts payable hereunder shall not be deemed to be consequential damages. Purchaser's rights to payment for its incremental costs of Energy and other NEPOOL Defined Products as damages in the event of a breach of this Contract shall not be deemed to be consequential damages. 28. Indemnity Each Party expressly agrees to indemnify, hold harmless and defend the other Party against all claims, liability, costs or expense for loss, damage or injury to persons or property in any manner directly or indirectly connected with or arising out of, the generation, transmission or distribution of electric energy on its own side of the Delivery Point. 29. Prior Agreements Superseded Unless otherwise specifically provided, upon the Effective Date this Contract supersedes any and all prior agreements and contracts by and between the Parties relative to Canal Unit 1, including without limitation the Original Contract. This Contract has been made within the Commonwealth of Massachusetts and shall bind and inure to the benefit of the Parties hereto and their respective successors and permitted assigns. IN WITNESS WHEREOF, the Parties have caused this Amended and Restated Power Sales Contract to be executed by their officers duly authorized thereunto and have duly caused their corporate or company seals to be affixed hereto.
