                            AMENDMENT NO. 6 TO
                  SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN
           FOR OFFICERS OF NORTHEAST UTILITIES SYSTEM COMPANIES


The Supplemental Executive Retirement Plan for Officers of Northeast Utilities
System Companies, as amended, is further amended, effective December 9, 2003,
as follows:

A.   The definition of Compensation is amended to read in its entirety
     as follows:

     "Compensation" shall have the same meaning as provided in the Retirement
Plan, but shall also include amounts disregarded pursuant to Section 401(a)(17)
of the Code, amounts (included in Compensation as earned) receipt of which is
deferred by a Participant pursuant to a plan or agreement which is not
qualified under the Code, and, for any period in question, awards under the
Incentive Plans to the extent made with respect to performance during such
period, each such award to be allocated on a pro rata basis to each of the
calendar months in the period to which it relates.  Effective November 1, 2001,
Long-Term Incentive Compensation Awards made under Incentive Plans after
November 1, 2001 shall not be included in Compensation for purposes of this
Plan, except that each individual who was a Participant prior to November 1,
2001 shall have credited to his or her Compensation in February each year
while a Participant, in the same manner as such amount was credited in 2001,
the "target" value of the stock option grants made to such Participant in
February, 2001 for purposes of the Make-Whole Benefit and, if such individual
was a Participant in the Target Benefit prior to October 2003, for purposes
of the Target Benefit as well.  For purposes of computing the value of a
Participant's awards under the Incentive Plans, awards made in common shares
of Northeast Utilities shall be valued by multiplying the per share New York
Stock Exchange closing price on the date the award is approved by the Board
by the number of shares awarded to such Participant.  Notwithstanding the
foregoing, if a Participant may become entitled to receive an award or awards
under the Incentive Plans, and if the amount of such award(s), if any, will be
determined after the date on which the Participant's Credited Service ends,
then a provisional calculation of the Participant's Compensation during the
period to which such award(s) relates (hereinafter the "Provisional
Calculation") shall be made on or before the date the Participant's Credited
Service ends, and benefits payable to the Participant under this Plan shall be
based upon the Participant's Compensation as determined under the Provisional
Calculation until such calculation is replaced as hereinafter provided.  A
Participant's Compensation shall be determined under the Provisional
Calculation by including the target amount of any award to the Participant
under the Incentive Plans as Compensation in the manner described in
the first two sentences of this definition.  The Provisional Calculation shall
be replaced by a permanent calculation of Compensation (hereinafter the
"Permanent Calculation") at the earliest possible date at which the amount of
all awards that the Participant may become entitled to receive under the
Incentive Plans has been determined, and as of such date the Participant's
benefit under this Plan shall be recalculated and thereafter paid based upon
the Participant's Compensation as determined under the Permanent Calculation.
The Permanent Calculation of a Participant's Compensation shall be determined
by including as Compensation the amount of awards, if any, to the Participant
under the Incentive Plans that are determined after the date on which the
Participant's Credited Service ends in the manner described in the first two
sentences of this definition.  If the amount of the Participant's benefit under
this Plan as determined under the Permanent Calculation is greater than the
amount of such benefit as determined under the Provisional Calculation, then
the Employer shall make a lump sum payment to the Participant within 30 days
following the date on which the Permanent Calculation is determined equal to
the difference between (i) the sum of the benefit payment(s) that would have
been made to the Participant hereunder from the date such payment(s) commenced
until the date on which the Permanent Calculation was determined if such
benefit(s) had been calculated based on the Participant's Compensation as
determined under the Permanent Calculation, and (ii) the actual benefit
Payment(s) made to the Participant hereunder for such period.  If the amount
of the Participant's benefit under this Plan as determined under the Permanent
Calculation is less than the amount of such benefit as determined under the
Provisional Calculation, then each of the Participant's benefit payments after
the date on which the Permanent Calculation is determined shall be reduced by
the amount that each benefit payment determined under the Provisional
Calculation exceeded the benefit payment that would have been made under the
Permanent Calculation until such time as the total amount of said reductions
equals the difference between (i) the actual benefit payment(s) made to
the Participant hereunder from the date such payment(s) commenced until the
date on which the Permanent Calculation was determined, and (ii) the sum of
such benefit payment(s) that the Participant would have received hereunder for
such period if such benefit had been calculated based on the Participant's
Compensation as determined under the Permanent Calculation.
