AMENDED AND RESTATED

ADDITIONAL POWER CONTRACT



AMENDED AND RESTATED ADDITIONAL POWER CONTRACT, dated as of April 30, 1984, as amended and restated as of the 1st day of July, 2004, between CONNECTICUT YANKEE ATOMIC POWER COMPANY ("Connecticut Yankee"), a Connecticut corporation, and (the names of the Purchasers appear in the attached Appendix A)  (the "Purchaser").



In consideration of the following understandings and the respective undertakings of the parties, it is agreed as follows:



1.         Basic Understandings



Connecticut Yankee was organized in 1962 to provide for the supply of power to its sponsoring utility companies (including the Purchaser). Connecticut Yankee constructed a nuclear electric generating unit of the pressurized water type, having a maximum net capability of approximately 582 megawatts electric, at a site adjacent to the Connecticut River atHaddam, Connecticut (said unit, together with the site and all related facilities owned or to be owned by Connecticut Yankee, being referred to herein as the "Unit"). On June 30, 1967, Connecticut Yankee was issued a full-term, operating license for the Unit from the Atomic Energy Commission (now the Nuclear Regulatory Commission, which, together with any successor agency or agencies, is hereafter called the "NRC"), which license expires on May 26, 2004, and the Unit commenced commercial operation on January 1, 1968.



The Unit is operated to supply power to the purchasers from Connecticut Yankee (collectively the "Purchasers"), each of which by a Power Contract dated as of July 1, 1964, as  supplemented by Supplementary Power Contracts dated as of March 1, 1978, such  Supplementary Power Contracts amended on August 22, 1980 and October 15, 1982 (collectively the "Power Contracts"), has undertaken to purchase a fixed percentage of the capacity and output of the Unit for a term extending through December 31, 1997. The names of the Purchasers and their respective percentages ("entitlement percentages") of the capacity and output of the Unit are as follows:

The Power Contracts have been supplemented most recently by Second Supplementary Power Contracts, dated as of 1984, between Connecticut Yankee and each of the Purchasers (the "Second Supplementary Power Contracts").  The Second Supplementary Power Contracts provide  for the collection of funds to defray the ultimate cost of decommissioning the Unit and to provide an allowance for potential taxes payable by Connecticut Yankee with respect to the decommissioning fund.



Connecticut Yankee and the Purchasers desire to provide for the orderly continuation of the sale and purchase of the capacity and output of the Unit during the useful life of the Unit to the extent that such useful life continues beyond the termination date of the Power Contracts and the Second Supplementary Power Contracts and to provide appropriate provisions for the collection of funds for, and the payment of, decommissioning costs and any other costs, including potential taxes, with respect to the Unit during and after the useful life of the Unit.



2.         Effective Date, Term and Waiver

This contract shall become effective upon receipt by the Purchaser of notice that Connecticut Yankee has entered into Additional Power Contracts, as contemplated by Section 1 above, with each of the other Purchasers.  The operative term of this contract shall commence on such date as may be authorized by the FERC and shall terminate on the date (the "End of Term Date") which is the later to occur of (i) 30 days after the date on which the last of the financial obligations of Connecticut Yankee which constitute elements of the payment calculated pursuant to Section 7 of this contract has been extinguished by Connecticut Yankee, or (ii) 30 days after the date on which Connecticut Yankee is finally relieved of all obligations under the last of any licenses (operating and/or possessory) which it now holds from, or which may hereafter be issued to it by, the NRC with respect to the Unit under applicable provisions of the Atomic Energy Act of 1954, as amended from time to time (the "Act'').



The Purchaser hereby irrevocably waives its right to extend the contract term of its Power Contract pursuant to subsections (a) or (b) of Section 8 thereof.

Outages for inspection, maintenance, refueling and repairs and replacements will be scheduled in accordance with good utility practice and insofar as practicable shall be mutually agreed upon by Connecticut Yankee and the Purchaser.  In the event of an outage, Connecticut Yankee will use its best efforts to restore the Unit to service as promptly as practicable.



4.         Decommissioning



After commercial operation of the Unit permanently ceases, Connecticut Yankee will decommission the Unit in a manner authorized by Connecticut Yankee's board of directors and approved by the NRC in accordance with the Act and the rules and regulations thereunder then in effect and by any agency having jurisdiction over decommissioning of the Unit.



It is understood that, pursuant to the 1987 Supplementary Power Contracts, the Purchasers are currently being billed for Total Decommissioning Costs which, as of the date of this contract, are being accumulated in a separate fund which was established for the purpose of reimbursing Connecticut Yankee for Decommissioning Expenses incurred in the process of decommissioning the Unit and that such billings ate subject to change in accordance with the provisions of the 1987 Supplementary Power Contracts, subject to the jurisdiction of the Federal Energy Regulatory Commission or any successor agency thereto (the "FERC").
