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

      This Agreement shall continue in full force and effect, with respect to
each Unit, for the useful life and decommissioning periods of Units 1, 2 and 3,
as applicable, unless earlier terminated with respect to any or all Millstone
Units by mutual agreement of NNECO and the respective Lead Participants or
owners of the affected Millstone Unit; provided, however, that this Agreement,
or any part thereof, shall be canceled to the extent and from the time that the
performance hereunder may conflict with any rule, regulation or order of the
Securities and Exchange Commission adopted before or after the execution hereof
under the provisions of the Public Utility Holding Company Act of 1935 or with
