Plan Benefits

1.   Retirement Benefit

     A Participant shall be entitled to receive from the Company 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.
<PAGE>
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, for Level A Participants, no reduction factors for
retirement prior to age 65 shall be applied against the 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% (100% if the Participant died after his
          or her 55th birthday and while an active employee) 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 or she 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

     In the event of the dissolution, liquidation, or winding up of the
business of the Company or the New England Electric System, whether voluntary
or involuntary, the Participant shall receive, at the time of such event, a
<PAGE>
lump sum payment equal to the full amount of the current Actuarial Value of
the Participant's benefits under this Supplemental Plan, unless the New
England Electric System, or its successor, has assumed all the rights, duties,
and obligations of the Company or New England Electric System hereunder. 

     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' Senior Incentive Compensation Plan, the New England Electric
Companies' Incentive Compensation Plan I, 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
a Participant's benefits under the Supplemental Plan shall be payable
immediately as a lump sum.  If any employer or company shall fail to make a
payment as provided in (i) or (ii) due to inadvertence or a good faith delay
to permit processing and shall immediately upon discovery of such failure or
delay make such payment in full, the original failure to make the payment or
payments shall not, for the purposes of this paragraph, be a failure to make a
payment.  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 or her benefits under the Supplemental
Plan if before the earlier of age 65 or five years following Termination of
Employment he or she, without the prior consent of the New England Electric
System's Chief Executive Officer (the "CEO") [or prior consent of the
Committee in the case of 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.

     The Benefits Committee 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.

Effectuation of Interest

     In the event it should become impossible for the Company, the Benefits
Committee, or other committee to perform any act required by the Plan, the
Company, the Benefits Committee, or other committee may perform such other act
as it in good faith determines will most nearly carry out the intent and
purpose of the Plan.

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.
