Signed /s/ [Illegible] ------------------ Date 27/7/01 ------------------ 15 SCHEDULE 1 THE NATIONAL GRID GROUP PLC AND THE NATIONAL GRID COMPANY PLC SPECIAL BONUS PLAN ARRANGEMENTS AND OTHER ITEMS EDWARD ASTLE This Schedule, should be read in conjunction with the Service Agreement between the National Grid Group plc and National Grid Company plc ("the Company") and Edward Astle. 1. SPECIAL BONUS SCHEME: You will participate in a special bonus scheme that will cover an initial Review period followed by the ongoing Delivery period. a) TO 31 MARCH 2002: REVIEW PERIOD: In addition to the annual performance bonus that applies to all Executive Directors, there will be an enhanced bonus delivering Pound Sterling 100,000 covering the period ending 31 March 2002. This bonus will be contingent on completing the telecommunications strategic review and gaining Board approval both for the review and for the business plans that result from the review. b) POST 31 MARCH 2002: DELIVERY PERIOD: When the strategy and business plans have been agreed, the Company will be in a much better position to set out a specific structure regarding incentives that reflect achievement and the realities of the telecommunications market. There are certain fundamental considerations that will underpin whatever structures are put in place. i) The special scheme will be in addition to the various incentive schemes that apply to the other Group Executive Directors. ii) Maximum achievement will deliver 100% of base salary on an annualised basis. iii) Target achievement will deliver about 66% of base salary on an annualised basis. iv) Assessment of achievement against targets will be determined by the Remuneration Committee. v) The special scheme will be structured in the way that best supports the achievement of whatever business objectives are agreed. The special scheme might be structured as an annual or 1 as a long-term plan (which may be a phantom option plan). If a long-term plan is set up, shareholder approval would need to be sought. If we are unable to draw up a mutually acceptable special scheme then the Company would recognise the importance of the telecommunications portfolio to enhancing NGG shareholder value by granting an increased multiple of share options for an additional two years after the initial grant. This multiple would be 3 times annual base salary. 2. IPO/DIVESTMENT An additional special bonus, recognising your personal contribution, will be paid in the event of an IPO or any divestment - subject to the transaction(s) significantly enhancing shareholder value. The Remuneration Committee will decide on the exact level of bonus - but an award of up to two times base salary would be envisaged for a successful and significant transaction. Corporate Finance will develop a method of calculating potential awards up to this level. 3. TERMINATION OF SERVICES, BY THE COMPANY, FOR REASONS UNRELATED TO YOUR PERFORMANCE AND OUTSIDE YOUR CONTROL i) In the event of termination you would have contractual notice which initially is for two years. ii) The special bonus (1(a) above) would still be paid in the event of termination on or before 31 March 2002. iii) For a termination after 31 March 2002 the Company would recommend to the Remuneration Committee that the a) Annual Bonus be paid in line with actual achievement against objectives for the pro-rated period to actual date of departure PLUS an amount equal to 50% of the outstanding notice period assessed at target achievement. b) Special Bonus (see 1(b) above) be paid in line with actual achievement against objectives for the pro-rated period to actual date of departure. iv) Notwithstanding 3 (iii)(a) and (b) above, the Remuneration Committee will be able, at its discretion, to determine whether any additional payment should be made, having regard to the circumstances prevailing at the time. v) The Remuneration Committee would have the discretion to grant a period of time wherein you could exercise National Grid Group Executive Share Options. vi) The above terms regarding termination of services will remain in force for the first three years of your employment. Thereafter termination terms will revert to those applicable to the other Executive Directors. 2 SCHEDULE 2 THE NATIONAL GRID GROUP plc and THE NATIONAL GRID COMPANY plc SUMMARY OF ENHANCED PENSION AND LIFE ASSURANCE ARRANGEMENTS EDWARD ASTLE This summary, which should be read in conjunction with the National Grid Company plc ("the Company") section of the ESPS booklet, notifies you of your entitlement to additional benefits to those provided by the ESPS. The additions are as follows: 1. Your Normal Pension Age is age 60. 2. Your pension will accrue at a rate of 1/30th of your Pensionable Salary for each year of Pensionable Service from 1st September 2001 (complete days will count) or such higher amount as may be advised by the Actuary to the Scheme, subject to pension payable, including any retained benefits, not exceeding Inland Revenue limits (but see 12 below). You will be able to exchange part of your pension for a tax free lump sum up to the maximum permitted by the Inland Revenue. The provisions of paragraph 12 of this Schedule shall apply in respect of any pension benefits which cannot be provided under the ESPS due to Inland Revenue limits. 3. (a) You may retire WITH the consent of the Companies at any time on or after your 55th birthday and receive an immediate pension. Under these circumstances, the immediate unreduced pension will be based on your Pensionable Service and your Pensionable Salary at the date of termination. (b) You may retire WITHOUT the consent of the Companies at any time on or after your 55th birthday and receive an immediate pension. Under these circumstances, the immediate pension will be based on your Pensionable Service and your Pensionable Salary at the date of termination, and will be reduced for early payment by an amount determined by the Remuneration Committee on the advice of the Actuary, having regard to the actuarial factors prevailing at that time within the ESPS. 1 4. Should your employment be terminated as a result of redundancy, and the termination is with the consent of the Companies, you will be entitled to the greater of: (a) the severance terms of The National Grid Group, as amended from time to time, which currently include payment of a pension under standard ESPS terms only, (i.e. not a pension based on the enhanced accrual rate set out in this summary) at age 50, or immediately if aged over 50, or; (b) a deferred pension (and lump sum) payable at your request from age 50, or such later date as you may choose but no later than 60. The pension (and lump sum) will be calculated on your Pensionable Service and your Pensionable Salary at the date of termination. Should such a termination occur after your 50th birthday you will be entitled to an immediate unreduced pension (and lump sum) calculated on your Pensionable Service and your Pensionable Salary at the date of termination. 5. In the event that it is agreed with the Companies that you should continue in service beyond age 60, there will be an appropriate adjustment to your benefits. The exact terms of the adjustment will be determined by the Companies and notified to you, upon advice received from the Actuary, when you reach age 60. 6. On death in service before the Normal Pension Age a lump sum is available for your beneficiaries equal to four times your annual rate of basic salary at death, plus the total amount of contributions with interest paid by you into the National Grid Company plc Section of the ESPS. 7.

You should note that the Inland Revenue have placed a restriction (the "earnings cap") on the amount of pay on which benefits may be calculated in an approved arrangement (L95,400 for the 2001/2002 Tax Year). Your pension at Normal Pension Age will be augmented under the National Grid Company plc Section of the ESPS, if necessary, up to the maximum allowable at that date. If your full pension promise, as set out in paragraph 2 of this Schedule, cannot be met from the National Grid Company plc Section of the ESPS, you will be provided with additional benefits of equivalent value under a separate agreement. For the avoidance of doubt, if your Pensionable Service is terminated (for any reason) prior to your Normal Pension Age you will be entitled at Normal Pension Age to pension benefits which give effect to your full pension promise as set out in paragraph 2 of this Schedule, but only in respect of your Pensionable Service up to the date of termination of your Pensionable Service, and this will apply mutatis mutandis to the provisions of paragraphs 3 and 4(b). With the exception of the earnings cap restriction, all other limits imposed by the Inland Revenue on approved arrangements will apply to the benefits referred to in this summary. 13. In all other respects the provisions of ESPS will apply to you. 3
