         Notwithstanding the foregoing, if any Participant has an employment agreement with a Company, National Grid USA, or National
Grid Group 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.

         7.04     Financial Objective Award.  If the Financial target is achieved, full credit will be given for the Financial
                  -------------------------
Objective.  The Financial Objective Bonus Award will be adjusted up or down to reflect results greater than, or less than, the
benchmark.

         7.05     Individual Objectives Award.  If each Performance Benchmark is fully met, the Participant will be eligible for the
                  ---------------------------
maximum Individual Objectives Bonus Award.  The Individual Objectives Bonus Award will be adjusted downward to reflect shortfalls in
Performance Benchmark achievement.

         7.06     Exercise of Discretion.  The Board, the Chief Executive Officer of National Grid Group plc, the CEO,  the Senior
                  ----------------------
Vice President, and/or member of Senior Management, as appropriate, are expected to use their judgment in evaluating performance,
with the objectives and benchmarks as standards, not cliffs.  The Board/CEO or the Chief Executive Officer of National Grid Group
plc, as appropriate may reduce bonuses from those calculated by the formula if circumstances warrant.  The Board/CEO or the Chief
Executive Officer of National Grid Group plc, as appropriate may also award bonuses outside those calculated by the formula.
Further, the Board/CEO or the Chief Executive Officer of National Grid Group plc, as appropriate retains the discretion, from time to
time, to add or delete Individual Objectives and to adjust benchmarks as deemed appropriate.

         7.07     Distribution.  When the books are closed at the end of the Plan Year, the Board or the Chief Executive Officer of
                  ------------
National Grid Group plc will determine the appropriate amount to be awarded to the CEO, the Chairman, and ICP I A Participants, and
the CEO will determine the appropriate amount to be awarded to all other Participants.  The Bonus Award will be distributed to
Participants by the July 15 following the Plan Year.

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

VIII.    PAYMENT UPON CHANGE OF CONTROL
         ------------------------------

         8.01     Change in 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.

         ------------------

pension plan calculations to the extent provided in said pension plans.

         9.02     Termination of Participation; Interplan Transfer.  Termination of participation shall be determined as follows:
                  ------------------------------------------------
                  (a)      the CEO and/or Chairman will be deemed Participants for the Plan Year regardless of the number of months
                           they are actively 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, and
                  (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 Participant for that
                           year on a proportional basis.

                The CEO will also determine the extent, if any, of participation by the person replacing a Participant.  If a

         proportional basis for each level, respectively.
