qualifications, select the ICP II and III Participants for the following year.
In addition, with the written consent of the CEO, qualified individuals may be
added to the Plan or transferred to different levels of the Plan during a Plan
Year.

      4.02 Notification. The Benefits Administrator shall notify those new
Participants who have been included in the Plan for the following year and those
Participants who have been dropped from the Plan for the following year.

V. PARTICIPANT'S COMPENSATION

      5.01 The compensation for each Participant will consist of two components:
Base Compensation and Incentive Compensation as described in Articles VI and VII
below.

VI. BASE COMPENSATION

      6.01 Base Compensation. A Participant's performance will be evaluated and
his or her base compensation, including any merit or promotional increase, will
be set in accordance with the National Grid USA salary management program.

                                       7



      6.02 Salary Approvals. The Board will approve all salary changes for the
CEO and/or Chairman, and the CEO will approve all salary changes for ICP I
Participants. For all other Participants, the Senior Vice President in charge of
his/her function will approve the Participant's salary change.

VII. INCENTIVE COMPENSATION

      7.01 Bonus Award. A Participant's Incentive Compensation (Bonus Award)
will be based upon the Participant's overall performance, comparison of the
Participant's performance and contributions in relationship to his/her peers,
and accomplishment of the Participant's individual objectives. At the beginning
of each Plan Year, Organizational Targets will be developed by the Board.
Individual objectives and measurements of success in support of these
Organizational Targets and business goals of the Company shall then be
established by the Board or the Chief Executive Officer of National Grid Transco
plc for the CEO and the Chairman, and for all other Participants; by the CEO or
appropriate senior management for each Plan Year.

      7.02 Target Payout. At the end of the Plan Year, the Board will measure
National Grid USA's performance in relation to the Organizational Targets. If
National Grid USA achieves its Organizational Targets, full credit will be given
to National Grid USA (Target Payout). The Target Payout will be adjusted up or
down, to reflect results greater than or less than the target. This will
determine the amount available for Bonus Awards for Participants for said Plan
Year.

      7.03 Bonus Award Measurement. At the end of the Plan Year, the
Participant's overall performance, performance in relationship to his/her peers,
and accomplishment of individual objectives will be assessed by the Board or the
Chief Executive Officer of National Grid Transco

                                       8



plc for the CEO and the Chairman, by the appropriate Senior Vice President for
the remaining ICP I Participants, and by senior management for ICP II and ICP
III Participants. Each Participant will be rated on a scale of 1-5.

1   =   Exceptional Performance
2   =   Excellent Performance
3   =   Good Performance
4   =   Poor Performance
5   =   Unsatisfactory Performance

      7.04 Bonus Award Payout. The Bonus Award payout will be based upon the
Participants ICP level and overall performance rating as set forth in Section
7.03 above. The Target Payout for ICP I is 45% of base compensation; for ICP
II-33% of base compensation and for ICP III-10% of base compensation. For
example, if the Plan pays out at target, a score of 1-5 will typically generate
the following payout levels:

1     Exceptional performance = 130 - 150% of target
2     Excellent performance = 100 - 130% of target
3     Good performance = 50 - 100% of target
4     Poor performance = 0 - 50% of target
5     Unsatisfactory performance = 0%

      7.05 Bonus Award Payment. Participant's in ICP I and II will receive two
thirds of their Bonus Award in cash and one-third in ADS's (which is the payment
referred to in Article 4.0 of Appendix B, the Incentive Share Plan). ICP III
Participants will receive their total Bonus Award in cash.

                                       9



      Notwithstanding the foregoing, the CEO and Chairman's Bonus Awards will be
determined in accordance with their respective Employment Agreement. Further, if
any other Participant has an employment agreement with a Company, National Grid
USA, or National Grid Transco plc that provides for percentages different than
those set forth above, the terms set forth in the Participant's employment
agreement shall supercede the terms set forth in the Plan.

      7.06 Exercise of Discretion. The Board, the Chief Executive Officer of
National Grid Transco plc, the CEO, the Senior Vice President, and/or member of
senior management, as appropriate, are expected to use their sound judgment in
evaluating a Participant's overall performance. In addition, they shall retain
the discretion to adjust Bonus Awards as they deem appropriate. Further, the
Board/CEO or the Chief Executive Officer of National Grid Transco plc, as
appropriate, retains the discretion, from time to time, to add or delete
performance measures and to adjust pay out percentages as deemed appropriate.

      7.07 Distribution. The Bonus Award will be distributed to Participants by
the June 15 following the Plan Year.

      Notwithstanding any other provision of this Plan, if the Annual Incentive
Share Award earned under the Share Plan cannot be distributed to Participants
within the time frame set forth in the Share Plan, then each Participant shall
receive from the Cash Plan, a cash amount that otherwise would have been awarded
in ADR's under the Share plan.

      7.08 Deferral of Cash. Notwithstanding anything in the Plan to the
contrary, a Participant in ICP I or II may elect to defer receipt of a Bonus
Award in accord with the terms and conditions of National Grid USA Companies
Deferred Compensation Plan. Thereafter, the Participants right to the deferred
compensation shall be governed solely by the terms of said Plan.

                                       10



VIII. PAYMENT UPON CHANGE OF CONTROL

      In the event of a Change in Control or Major Transaction, each Participant
will receive, within 30 days of the consummation of the (1) Change in Control or
(2) of the transaction approved by the Major Transaction, a cash payment equal
to (a) the average of the bonus percentages for the Plan for the last three
years prior to the Change in Control or consummation of the transaction approved
by the Major Transaction times the Participant's annualized Base Compensation;
or if the Plan has not been in effect for three years, then the average of the
bonus percentage for the Plan and the preceding plan, New England Electric
Companies' Senior Incentive Compensation Plan or New England Electric Companies'
Incentive Compensation Plans I, II, or III and (b) a Matching Percentage based
upon the average of the bonus percentages for the Plan for the last three years
prior to the Change in Control or consummation of the transaction approved by
the Major Transaction times the Participant's annualized Based Compensation; or
if the Plan has not been in effect for three years, then the average of the
bonus percentage for the Plan and the preceding plan, New England Electric
Companies' Senior Incentive Compensation Plan or New England Electric Companies'
Incentive Compensation Plans I, II, or III. Further, if the consummation of the
Change in Control or of the transaction approved by the Major Transaction occurs
prior to the determination and payment of the Bonus Award for the prior Plan
Year, the Participant will also receive within 30 days a cash payment equal to
(a) said percentage times the Participant's Base Compensation received in the
prior Plan Year and (b) an amount based upon that amount that the Participant
would receive as a Matching Percentage based upon the percentage under the Plan
times the Participant's Base Compensation received in the prior Plan Year. No
further benefits will be payable from the Plan.

IX. GENERAL PROVISIONS

      9.01 Other Benefit Plans. Bonus Awards will not be used in determining the

other than the Share Plan. Notwithstanding the foregoing, Bonus Awards will be
included in pension plan calculations to the extent provided in said pension
plans.

determined as follows:

            (a)   The CEO and/or Chairman will be deemed Participants for the

                  employed in a Plan Year unless otherwise specified in their
                  Employment Agreement.

            (b)   If, for any reason, a Participant should cease to be actively
                  employed by a subsidiary of National Grid USA prior to October
                  1 of a Plan Year, that person will not be deemed a Participant
                  for that year unless the CEO determines there are
                  extraordinary circumstances which justify inclusion.

            (c)   A Participant who is actively employed during the first six
                  months of the Plan Year, but ceases to be so actively employed
                  during the last six months of a Plan Year will be deemed a

III. ADMINISTRATION

      3.01 Administration and Interpretation. The Plan shall be administered by
the Benefits Administrator and interpretations of the Plan or other
determinations with respect to the Plan by the Benefits Administrator shall be
final and binding on all parties. Determinations or interpretations affecting
the Benefits Administrator, individually shall be made by the CEO and such
determinations or interpretations shall be final and binding all parties.

any time, provided that no such action shall affect any right or obligation with
respect to any Bonus Award previously granted.

                                       3



      3.03 Effectuation of Interest. In the event it should become impossible
for the Benefits Administrator, the CEO, the Chief Executive Officer of National
Grid Transco plc, or National Grid USA to perform any act required by the Plan,
the Benefits Administrator, the CEO, the Chief Executive Officer of National
Grid Transco, or National Grid USA may perform such other act as it in good
faith determines will most nearly carry out the intent and purpose of the Plan.

      3.04 Accounting. The Vice President and Controller of National Grid USA
will be responsible for accounting matters directly affecting the Plan.

IV. ANNUAL INCENTIVE SHARE AWARD

      4.01 Calculation of Award. Each Participant's Annual Incentive Share Award
shall be determined by multiplying the Participant's Cash Bonus by the
applicable Matching Percentage. Notwithstanding the foregoing, if any
Participant has an employment agreement with National Grid USA or National Grid
Transco plc that provides for percentages different than those set forth herein
the terms set forth in the Participant's Employment Agreement shall supersede
the terms set forth in the Plan.

      4.02 Purchase of ADS's. The Company will purchase ADS's in the
Participant's name, based upon the number of ADSs awarded to the Participant
under Section 4.01 above. The number of ADSs purchased or will be rounded up to
the next whole ADS.

      The Board/CEO may require each Company to deposit cash in a trust as
needed to acquire the requisite number of ADS's for awards as they are
determined. The Trustee will invest the cash in ADS's as soon as practicable.
Any ADS's acquired by the Trustee shall be held until all

                                       4



awards have been invested in ADS's. Any awards held in trust shall be held for
the exclusive benefit of the Participants.

      The price of ADS's will be computed on the basis of the average of high
and low prices on the New York Stock Exchange - Composite Transactions as
reported in the Wall Street Journal for the five consecutive trading days ending
on the trading day prior to the fifteenth day of April following the Plan Year
for which the award applies. If there is no trading in ADS's on the New York
Stock Exchange for a substantial amount of time during the five-day period, or
if publication by The Wall Street Journal of reports of ADS transactions for any
day in the five-day period does not take place or is subject to reporting error,
the value of ADS's shall be determined on the basis of such market quotations or
other method as National Grid Transco plc shall deem appropriate.

      The price of ADS's purchased on the open market shall not include
commissions. To the extent ADS's held by the Trustee earn cash dividends, said
dividends shall be allocated and distributed to Participants on a pro-rata
basis.

      4.03 Timing of Purchase. Purchase of ADS's under the Plan shall take place
as soon as practicable following the end of the Plan Year for which the Annual
Incentive Share Award applies.

      4.04 Restriction on Shares/ADS's .

      (a)   Subject to Section 4.04(b), all Shares/ADS's awarded under the Plan
            to officers of National Grid USA or its predecessor, pertaining to
            performance in 1996 and thereafter, shall not be commuted, sold,
            assigned, transferred, or otherwise conveyed, whether voluntarily or
            involuntarily, for a period of five years from

                                       5



            issuance, provided, however, said Shares/ADS's may be deferred to
            National Grid USA's Deferred Compensation Plan.

      (b)   In the event of the Participant ceasing to be employed by a Company,
            the Board/CEO can determine whether any vesting restriction and/or
            any restriction on the freedom to dispose of the Shares/ADs's shall
            be waived or commuted.

      (c)   All Shares/ADs's awarded under the Plan to the CEO and/or Chairman,
            as of 2000 and thereafter shall be subject to any vesting
            requirements set forth in his/her applicable employment agreement.

      4.05 Distribution Date. Except as set forth above, the ADS's shall be
distributed to the Participants by the June 15 following the Plan Year.

      4.06 Deferral of ADS's Notwithstanding anything in the Plan to the
contrary, a Participant in ICP I or II may elect to defer receipt of an Annual
Incentive Share Award according to terms and conditions of National Grid USA
Companies Deferred Compensation Plan. Thereafter, the Participant's rights to
