Plan Benefits
- -------------
1.   Retirement Benefit
     ------------------
     A Participant shall be entitled to receive for retirements
on or after April 1, 1991, an annual retirement benefit equal to
(a) plus (b) plus (c) plus (d) plus (e) less (f) less (g) below:
     (a)  1.5% of Final Average Total Compensation for each Year
          of Service up to 10 years;
     (b)  1.3% of Final Average Total Compensation for each Year
          of Service from 11 to 20 years;
     (c)  1.25% of Final Average Total Compensation for each
          Year of Service from 21 to 30 years;
     (d)  .6% of Final Average Total Compensation for each Year
          of Service over 30 years;
     (e)  .57% of Final Average Total Compensation in excess of
          the Average Social Security Wage Base for each Year of
          Service, up to 35 years;

     (f)  any benefit payable on a straight life annuity basis
          which was accrued, under a plan maintained by an
          employer other than a New England Electric System
          company, for service granted pursuant to the
          additional service credits provision of the Qualified
          Plan; and
     (g)  the Qualified Plan Benefit.
All of the above amounts are to be determined as at the
Participant's Termination of Employment.

2.   Form of Payment
     ---------------
     Retirement Income shall be payable in the normal form as
follows:
     (a)  If a Participant has a Spouse, the normal form of
          payment shall be a contingent annuitant option with
          the Spouse, as contingent annuitant, entitled to
          receive 50% of the Participant's reduced amount of
          Retirement Income.
     (b)  If a Participant does not have a Spouse, the normal
          form of payment shall be a straight life annuity with
          no amount of Retirement Income payable after the
          Former Participant's death.
     If a Participant elects an optional form of payment under
the Qualified Plan, the same option and actuarial equivalent

factors shall apply to Retirement Income payable under the
Supplemental Plan; provided, however, to the extent the form of
benefit was dictated by the terms of a qualified domestic
relations order, the form may be that which would have applied
(or any form that could have been elected) in the absence of said
order.  In calculating the benefit payable under any option, the
same actuarial equivalent factors in the Qualified Plan shall be
used in the Supplemental Plan except that no reduction factors
for retirement prior to age 65 shall be applied against a
Participant's Retirement Income.

3.   Spouse's Death Benefit
     ----------------------
     The Spouse of a Participant vested under the Qualified Plan
who has not had a Termination of Employment is entitled to a
pre-retirement spouse benefit, if the Participant dies before
payment of benefits commence.
     The Spouse will be entitled to receive an annual benefit
determined as follows:
     (a)  as if the Participant had retired and elected
          Retirement Income payments to begin on the first day
          of the month next following the later of the date of
          death or Participant's fifty-fifth birthday, and
     (b)  the Retirement Income was payable in the form of a
          contingent annuitant option with the Spouse, as

          contingent annuitant, entitled to receive 50% of the
          Participant's amount of Retirement Income subject to
          reduction for benefits payable hereunder under a
          domestic relations order.

Timing of Payments
- -----------------
     A Participant shall be eligible for benefits under the
Supplemental Plan when and if he is eligible for benefits under
the Qualified Plan, except as provided herein.  Benefits shall
commence on the date on which the Participant or the Spouse first
receives benefits under the Qualified Plan.

Lump Sum Payments
- -----------------
     Any provision of the Supplemental Plan to the contrary
notwithstanding, if (i) any company shall fail to make any
payment to any Participant when due under the Supplemental Plan 
or (ii) the employer or company shall fail to make any payment to
any participant due under any of the New England Electric
Companies' Incentive Compensation Plan, the New England Electric
Companies Deferred Compensation Plan, or the New England Electric
System Companies Retirement Supplement Plan, the full amount of
the current Actuarial Value of his benefits under the
Supplemental Plan shall be payable immediately to each

Participant as a lump-sum; provided, however, if any employer or
company shall, in good faith, contest a claim by a participant
under this Supplemental Plan or any of the other above-listed
plans, the failure to make the contested payment or payments
shall not, for the purpose of this paragraph, be a failure to
make a payment.
     At any time following a Change in Control or Major
Transaction, any Participant who has had a Termination of
Employment, whether before or after the Change in Control or
Major Transaction, may elect to receive, in lieu of any future
benefits hereunder, a lump sum payment equal to the Actuarial
Value of the maximum value of said future benefits, less 10%.
     If the Company does not make the aforesaid lump sum
payments, the New England Electric System will make the payment
for the account of the Company.

Vesting and Forfeiture of Benefits
- ----------------------------------
     Except as provided in the following paragraph, a
Participant's accrued benefit shall be 100% vested after five
Years of Service.
     A Participant will forfeit his benefits under the
Supplemental Plan if before the earlier of age 65 or five years
following termination of employment he, without the prior consent
of the New England Electric System's Chief Executive Officer (the

"CEO"), enters into or in any manner takes part in, as an
employee, agent, officer, owner, or otherwise, any business or
authority which in the opinion of the CEO is in competition with,
in the same field as, or regulating the business of New England
Electric System or any of its subsidiaries, or which in the
opinion of the CEO provides services peculiarly essential to
utility operation.  Violation of this provision will result in
termination of payments, and any obligations to make future
payments to the Participant and the Participant's Spouse.
     A Participant may request to have the Committee review any
decision made by the CEO under this provision that adversely
affects the Participant.  The Committee's decision shall be
final.
     Upon the occurrence of a Change in Control or a Major
Transaction, the second paragraph of this section shall no longer
have any effect.

Administration and Claims
- -------------------------
     The Administrator shall have for the Supplemental Plan the
same duties as for the Qualified Plan, except as specifically
provided herein.  The Benefits Appeal Committee for the Qualified
Plan shall have for the Supplemental Plan the same duties
relative to denied claims as for the Qualified Plan, except as
may be specifically provided herein.

Government Regulations
- ----------------------
     It is intended that the Supplemental Plan will comply with
all applicable laws and governmental regulations, and the Company
shall not be obligated to perform an obligation hereunder in any
case where, in the opinion of the Company's counsel, such
performance would result in violation of any law or regulation.

Nonassignment
- -------------
     To the fullest extent permitted by law, no benefit under the
Plan, nor any other interest hereunder of any Participant,
Spouse, or contingent annuitant, shall be assignable,
transferable, or subject to sale, mortgage, pledge,
hypothecation, commutation, anticipation, garnishment,
attachment, execution, or levy of any kind.

Provisions of Benefits
- ----------------------
     The Supplemental Plan will be unfunded.  Benefits will be
paid from the operating revenues of the Company.  A Participant's
rights to benefits under the Supplemental Plan shall be those of
an unsecured, general creditor of the Company.


Amendment or Discontinuance
- ---------------------------
     The Committee may amend or discontinue the Supplemental Plan
at any time; provided, no modification shall reduce a benefit
which a Participant was eligible to receive under the
Supplemental Plan at the time of such amendment or
discontinuance; and provided further, no amendment or
discontinuance in any manner adverse to a Participant with
respect to benefit formula or optional form of payment may be
made for three years following a Change in Control or a Major
Transaction.

Effective Date
- --------------
     The Plan, as amended, is to be effective for retirements on
and after January 1, 1995.
