                                    AMENDMENT
                                       TO
                         SEVERANCE PROTECTION AGREEMENT

      The Agreement dated March 1, 1998, between New England Electric System, a
Massachusetts business trust (the Company), and John G. Cochrane (the Executive)
is hereby amended by amending Section 6.2 to read as follows:

            6.2 Notwithstanding any other provisions of this Agreement, in the
      event that any payment or benefit received or to be received by the
      Executive in connection with a Change in Control or a Major Transaction,
      or the termination of the Executive's employment (whether pursuant to the
      terms of this Agreement or any other plan, arrangement or agreement with
      the System, any Person whose actions result in a Change in Control or a
      Major Transaction or any Person affiliated with the System or such Person)
      (all such payments and benefits, including the Severance Payments, being
      hereinafter called Total Payments) would be subject (in whole or part), to
      the Excise Tax, then the Severance Payments shall be reduced to the extent
      necessary so that no portion of the Total Payments is subject to the
      Excise Tax (after taking into account any reduction in the Total Payments
      provided by reason of section 280G of the Code in such other plan,
      arrangement or agreement) if (A) the net amount of such Total Payments, as
      so reduced, (and after deduction of the net amount of federal, state and
      local income tax on such reduced Total Payments) is greater than (B) the
      excess of (i) the net amount of such Total Payments, without reduction
      (but after deduction of the net amount of federal, state and local income
      tax on such Total Payments), over (ii) the amount of Excise Tax to which
      the Executive would be subject in respect of such Total Payments. For
      purposes of determining whether and the extent to which the Total Payments
      will be subject to the Excise Tax, (i) no portion of the Total Payments
      the receipt or enjoyment of which the Executive shall have effectively
      waived in writing prior to the Date of Termination shall be taken in to
      account, (ii) no portion of the Total Payments shall be taken into account
      which in the opinion of tax counsel selected by the Company does not
      constitutes a "parachute payment" within the meaning of section 280G(b)(2)
      of the Code, (including by reason of section 280G(b)(4)(A) of the Code)
      and, in calculating the Excise Tax, no portion of such Total Payments
      shall be taken into account which constitutes reasonable compensation for
      services actually rendered, within the meaning of section 280G(b)(4)(B) of
      the Code, in excess of the Base Amount allocable to such reasonable
      compensation, and (iii) the value of any noncash benefit or any deferred
      payment or benefit included in the Total Payments shall be determined by
      the Company in accordance with the principles of sections 280G(d)(3) and
      (4) of the Code. Prior to the payment date set forth in Section 6.3
      hereof, the Company shall provide the Executive with its calculation of
      the amounts referred to in this Section and such supporting materials as
      are reasonably necessary for the Executive to evaluate the Company's
      calculations. If the Executive objects to the Company's calculations, the
      Company shall pay to the Executive such portion of the Severance Payments
      (up to 100% thereof) as the Executive determines is necessary to result in
      the Executive receiving the greater of clauses (A) and (B) of this
      Section.

            replaced with the following: "Further, a Notice of Termination for
            Cause is required to include a statement from the Chief Executive
            Officer of National Grid USA and the Chief Executive Officer of
            National Grid Transco plc or his designee, that, in the good faith
            opinion of the two (after reasonable notice to the Executive and an
            opportunity for the Executive, together with the Executive's
            counsel, to be heard) that the Executive was guilty of conduct set
            forth in clause (i) or (ii) of the definition of Cause set forth in
            Section 15 (D) of this Amendment. Said statement shall specify the
            particulars thereof in detail.

      2.    Section 15. Definitions. The Definitions shall read as follows:

            (A)   "Beneficial Owner" - delete.

            (B)   "Base Amount" shall have the meaning defined in Section 280 G
                  (b) (3) of the Code.

            (C)   "Board" or "Board of Directors of the Company" - all
                  references to "Board" or "Board of Directors" shall be
                  replaced with Chief Executive Officer of National Grid USA and
                  Chief Executive Officer of National Grid Transco plc, or his
                  designee, unless otherwise specified in this Amendment.

            (D)   "Cause" for termination by the Employer of the Executive's
                  employment, after any Change in Control or Major Transaction,
                  shall mean (i) the willful and continued failure by the
                  Executive to substantially perform the Executive's duties with
                  the System (other than any such failure resulting from the
                  Executive's incapacity due to physical or mental illness or
                  any such actual or anticipated failure after the issuance of a
                  Notice of Termination for Good Reason by the Executive
                  pursuant to Section 7.1 of the Agreement and this Amendment)
                  after a written demand for substantial performance is
                  delivered to the Executive by the Board, which demand
                  specifically identifies the manner in which the Board believes
                  that the Executive has not substantially performed the
                  Executive's duties, or (ii) the willful engaging by the
                  Executive in conduct which is demonstrably



                  and materially injurious to the System, monetarily or
                  otherwise. For purposes of clauses (i) and (ii) of this
                  definition, no act, or failure to act, on the Executive's part
                  shall be deemed "willful" unless done, or omitted to be done,
                  by the Executive not in good faith and without reasonable
                  belief that the Executive's act, or failure to act, was in the
                  best interest of the System.

            (E)   A "Change in Control" shall be deemed to have occurred if the
                  conditions set forth in any of the following paragraphs shall
