AMENDED AND RESTATED MILLSTONE PLANT AGREEMENT This Amended and Restated Millstone Plant Agreement (the "Agreement") is dated as of December 1, 1984, and is by and among Northeast Nuclear Energy Company ("NNECO"), The Connecticut Light and Power Company ("CL&P"), and Western Massachusetts Electric Company ("WMECO"). BACKGROUND CL&P, WMECO and NNECO are parties to an Amended and Restated Millstone Plant Agreement dated as of December 1, 1982 (the "Millstone Plant Agreement"), which is a comprehensive restatement and amendment of a prior agreement dated as of June 30, 1966, as supplemented by a Supplemental Agreement dated as of December 1, 1967 and as amended by an amendment dated as of December 1, 1972. Under the Millstone Plant Agreement, NNECO agreed to act as CL&P's and WMECO's agent for the following purposes: (1) Operating and maintaining Millstone 1 and 2 ("Unit 1" and "Unit 2," respectively), which are two nuclear electric generating units located at a site of approximately 500 acres (the "Millstone Site") at Millstone Point in the Town of Waterford, Connecticut, in which units CL&P and WMECO have 81 percent and 19 percent, respectively, joint ownership interests as tenants in common, and (2) Designing, constructing, operating, and maintaining a third nuclear generating unit ("Unit 3") located at the Millstone Site, as agent for CL&P and WMECO in their capacities as Lead Participants for Unit 3 pursuant to a Sharing Agreement dated as of September 1, 1973, as amended on August 1, 1974 and December 15, 1975 (as the same may be further amended or modified from time to time, and in effect, the "Sharing Agreement"), by and among CL&P and WMECO and the Associate Participants (as defined in the Sharing Agreement) named therein. When the Millstone Plant Agreement was amended and restated in 1982, it was contemplated that NNECO would arrange under separate agreements to construct and finance a building (the "Simulator Building") at the Millstone Site in which would be located a separate control room simulator for each of Unit 1 (the "Unit 1 Simulator"), Unit 2 (the "Unit 2 Simulator"), Unit 3 (the "Unit 3 Simulator") (collectively the "Millstone Simulators") and a nuclear electric generating unit (the "Haddam Neck Unit") owned and operated by Connecticut Yankee Atomic Power Company ("CYAPC") in the Town of Haddam, Connecticut (the "CY Simulator") (each a "Simulator" and all four collectively the "Simulators"). It was also contemplated at that time that the Niantic Bay Fuel Trust would assume all of NNECO's prior responsibilities for procuring, supplying and financing nuclear fuel on behalf of CL&P and WMECO. Subsequently, it has been determined that it is desirable for NNECO to acquire the Millstone Simulators and the Simulator Building upon their completion and to operate and maintain the Simulator Building for CL&P and WMECO with respect to the Unit 1 and 2 Simulators, for CL&P, WMECO and the Associate Participants with respect to the Unit 3 Simulator, and for CYAPC with respect to the CY Simulator. In furtherance thereof, NNECO and CYAPC have entered into an agreement as of the date hereof (the "CYAPC Agreement") setting forth the rights and responsibilities of NNECO and CYAPC with respect to the CY Simulator and the Simulator Building. It has also been recognized that there are many opportunities for NNECO to apply its nuclear engineering, construction and operations expertise for the benefit of the Northeast Utilities System and/or the Associate Participants, and that there may in the future be benefits to the Northeast Utilities system and/or the Associate Participants in having NNECO assume all or part of the functions involved in procuring, financing, owning, leasing (as lessor or lessee) and otherwise performing supply and disposal functions with respect to nuclear fuel, the Simulators, the Simulator Building, and any other assets for any one or more of Units 1, 2 and 3 (collectively the "Millstone Units"). Accordingly, the parties desire to restate further the Millstone Plant Agreement to remove the current restrictions on NNECO's activities with respect to the Simulator Building and the Millstone Simulators, and to provide more generally for NNECO to render such services with respect to the Millstone Units and the nuclear fuel for the Millstone Units as CL&P and/or WMECO may from time to time request. AGREEMENTS Now, therefore, in consideration of the premises and the mutual agreements hereinafter contained, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows: 1. Description of Millstone Plant and Ownership. CL&P and WMECO own the Millstone Site as tenants in common. Unit 1, a 660 MW boiling water reactor nuclear electric generating unit, and Unit 2, an 870 MW pressurized water reactor nuclear electric generating unit, are both currently licensed for operation at the Millstone Site. Unit 3, a 1,150 MW pressurized water reactor electric generating unit, is under construction at the Millstone Site and is scheduled to begin commercial operations in May, 1986. CL&P owns an 81 percent undivided interest in Units 1 and 2, the portion of the Millstone Site on which Units 1 and 2 are located, and all existing and future improvements thereto, except for a refuel outage building, the Simulator Building and the Simulators, and WMECO owns an 19 percent interest similarly therein. These percentage interests, as the same may change from time to time to reflect the acquisition or disposition of interests in Units 1 and 2, are hereinafter referred to as the "Unit 1 and 2 Ownership Percentages." Pursuant to the Sharing Agreement, CL&P and WMECO collectively own a 64.85 percent undivided interest in Unit 3 (representing approximately 745.8 MW), the portion of the Millstone Site on which Unit 3 is located, and all existing and future improvements thereto. CL&P and WMECO presently own, respectively, 52.6115 percent (605.032 MW) and 12.2385 percent (140.743 MW) undivided interests in Unit 3. These shares, as the same may change from time to time as a result of acquisition or disposition of undivided interests in Unit 3 in compliance with the Sharing Agreement, are hereinafter referred to as the "Unit 3 Ownership Percentages." Certain facilities and structures constructed on or used in connection with the Millstone Site, including but not limited to, an information center, a training building, an emergency operations center, the refuel outage building, and warehouses, serve Units l, 2 and 3. Such facilities and structures (other than the Simulator Building), and all renewals, replacements, additions, retirements and modifications thereto, are hereinafter referred to as the "Millstone Common Facilities." Title to the Millstone Common Facilities (other than the refuel outage building, which is owned by Interet Land Co. and leased to CL&P and WMECO) is held by CL&P and WMECO in accordance with their Unit 1 and 2 Ownership Percentages. For the purposes of this Agreement, Units 1, 2 and 3, the associated transmission substations, the Millstone Common Facilities and other related facilities (other than [i] related transmission lines and rights of way, which are to be separately owned, and [ii] the Simulator Building and the Simulators), are hereinafter referred to as the "Millstone Plant." 2.
