NATIONAL GRID GROUP plc S/David C. Forward By_________________________ Name: David C. Forward Title: Assistant Secretary Date: April 22, 2002 Part 1 EMBARGOED UNTIL 7:00 A.M. 22 April 2002 NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION IN WHOLE OR IN PART IN OR INTO CANADA, AUSTRALIA OR JAPAN MERGER OF NATIONAL GRID AND LATTICE TO CREATE A LEADING INTERNATIONAL ENERGY DELIVERY COMPANY The directors of National Grid and Lattice announce that they have unanimously agreed the terms of a recommended merger of equals to form National Grid Transco. National Grid Transco will: - be a leading international energy delivery company combining two groups, each of which has a proven track record of operating complex energy networks safely and reliably within incentive based regulatory environments; - utilise the complementary skills of the two groups to maximise shareholder value from its existing UK and US assets through enhanced operating performance and the sharing of best practice; - offer an enhanced operational and financial platform for future growth in the liberalising energy markets; - have a combined market capitalisation of approximately 14.8 billion pounds sterling (based on the National Grid Closing Price and the Lattice Closing Price on 19 April 2002) and become the UK's largest utility. The Merger will: - generate pre-tax financial benefits that are expected to reach an annualised rate of at least 100 million pounds sterling by the end of the first full financial year following completion of the Merger. The directors of National Grid and Lattice believe that these financial benefits will arise principally from the elimination of duplicate head office costs and other central cost savings and from combining the support services provided to the UK regulated electricity and gas businesses; - generate further savings from the progressive combination of the operations of the two UK transmission businesses, sharing best practice between the US and UK businesses and further financial synergies; - create a combined group with significant balance sheet strength and strong operational cash flows. The Merged Group will seek to maintain a single A credit rating. National Grid Transco Shareholders will benefit from: - enhanced earnings per share (pre-exceptional items) in the first full financial year following completion of the Merger; (1) - a progressive dividend policy. The Merged Group intends to adopt National Grid's existing dividend policy of aiming to increase dividends per share by 5 per cent. in real terms per annum for each year to 31 March 2006; - the Merged Group taking advantage of opportunities presented by the liberalising international energy markets, in particular by building upon National Grid's successful US strategy. The terms of the Merger are based on the recent relative equity market capitalisations of the two companies. Under the terms of the Merger, National Grid Shareholders will retain their shares in National Grid (to be renamed National Grid Transco) and Lattice Shareholders will receive 0.375 New National Grid Transco Shares for each Lattice Share. Upon completion of the Merger, National Grid Shareholders will hold approximately 57.3 per cent. and Lattice Shareholders will hold approximately 42.7 per cent. of the issued share capital of National Grid Transco, based on the current issued share capital of the two companies. Lattice Shareholders will remain entitled to receive Lattice's second interim dividend of 5.4 pence per Lattice Share to be paid on 14 June 2002. National Grid Shareholders will have the right to receive the National Grid Final Dividend of 9.58 pence per National Grid Share to be paid on 15 August 2002. New National Grid Transco Shares, issued pursuant to the Merger, will rank pari passu with the existing National Grid Shares save that they will not be entitled to receive the National Grid Final Dividend. The Board of National Grid Transco will be drawn from the boards of National Grid and Lattice. Sir John Parker will be Non-Executive Chairman. James Ross will be Non-Executive Deputy Chairman. Roger Urwin ---------- (1) The statement that the Merger will be earnings per share enhancing for National Grid and Lattice should not, however, be interpreted to mean that earnings per share in the first full financial year following the Merger, or in any subsequent period, will necessarily be greater than those for the relevant preceding financial period. will be Group Chief Executive and Steve Lucas will be Group Finance Director. The remaining executive directors, drawn from National Grid and Lattice, will be Edward Astle, Steve Holliday, Colin Matthews, Rick Sergel and John Wybrew. Stephen Box, National Grid Finance Director, will take early retirement on the grounds of ill-health upon the completion of the Merger. The Merger is intended to be implemented by way of a scheme of arrangement between Lattice and its shareholders under section 425 of the Companies Act. The Merger is subject to a number of conditions, including regulatory consents and approvals in the UK and the US, the sanction of the Court and the approval of the shareholders of both National Grid and Lattice. The Merger is expected to complete during the autumn of 2002. Commenting on today's announcement, James Ross, Chairman of National Grid, said: "This merger is born of complementarity, proven skills and a clear, mutually shared recognition of how National Grid and Lattice together will create greater value for all stakeholders. National Grid Transco will be a truly world class energy delivery company." Commenting on today's announcement, Sir John Parker, Chairman and acting Chief Executive of Lattice, said: "The combination of Lattice and National Grid will create a leading international energy company with significant cost saving and synergy potential. The Merger creates a platform for growth which will allow National Grid Transco to realise significant value for shareholders." Commenting on today's announcement, Roger Urwin, Chief Executive of National Grid, said: "The fit of skills, experience and resources of National Grid and Lattice are as near perfect as you can find. We will build upon the records of both companies to drive further improvements in operating performance in both our UK and US businesses. We shall also deploy the combined resources and financial capacity of National Grid Transco to take advantage of opportunities in the liberalising energy markets abroad, in particular extending National Grid's successful US strategy."

Part 2 22 April 2002 NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION IN WHOLE OR IN PART IN OR INTO CANADA, AUSTRALIA OR JAPAN MERGER OF NATIONAL GRID AND LATTICE TO CREATE A LEADING INTERNATIONAL ENERGY DELIVERY COMPANY 1. Introduction The directors of National Grid and Lattice announce that they have unanimously agreed the terms of a recommended merger of equals to form National Grid Transco. The terms of the Merger are based on the recent relative equity market capitalisations of the two companies. Under the terms of the Merger, National Grid Shareholders will retain their shares in National Grid (to be renamed National Grid Transco) and Lattice Shareholders will receive 0.375 New National Grid Transco Shares for each Lattice Share held at the relevant record date. Upon completion of the Merger, National Grid Shareholders will hold approximately 57.3 per cent. and Lattice Shareholders will hold approximately 42.7 per cent. of the issued share capital of National Grid Transco, based on the current issued share capital of the two companies. Lattice Shareholders will remain entitled to receive Lattice's second interim dividend of 5.4 pence per Lattice Share to be paid on 14 June 2002. National Grid Shareholders will have the right to receive the National Grid Final Dividend of 9.58 pence per National Grid Share to be paid on 15 August 2002. Rothschild is acting as financial adviser to National Grid and Credit Suisse First Boston and Merrill Lynch are acting as joint corporate brokers. JPMorgan and Cazenove are acting as joint financial advisers to Lattice and Hoare Govett and Cazenove are acting as joint corporate brokers. 2. BENEFITS ARISING FROM THE MERGER The Boards of National Grid and Lattice believe that the Merger will create a business which is able to generate superior returns for shareholders from opportunities in a number of areas: Creation of a leading international energy delivery company The Merger will create a leading international energy delivery company with a combined market capitalisation of approximately 14.8 billion pounds sterling (based on the National Grid Closing Price and the Lattice Closing Price). In Great Britain, Lattice owns and manages the principal gas transportation system, comprising approximately 6,400 km of high pressure pipelines and around 275,000 km of lower pressure (local transmission and distribution) pipelines. National Grid owns and manages the high-voltage electricity transmission network in England and Wales, comprising approximately 8,000 km of overhead lines and underground cables. Lattice is continuing to make good progress on restructuring Transco into the National Transmission System and eight Regional Distribution Networks. National Grid Transco will work constructively with Ofgem to facilitate the creation of individual price controls to provide the Merged Group with flexibility and structural options for the future. In the US, National Grid has electric transmission and distribution assets with a total length of approximately 140,000 km, serving over 3.2 million electricity customers. It also has a gas distribution network, comprising approximately 15,000 km of pipelines and mains, serving over 0.5 million customers in New York State. Both National Grid and Lattice utilise their existing infrastructure to provide solutions to the wireless communications industry. Combined, the enlarged business will be the third largest independent communication towers provider in the UK. Together the businesses will provide broader coverage to mobile operators and be well positioned to exploit growth opportunities. The strategic options for 186k, Lattice's fibre-optic telecommunications business, are being reviewed with a view to resolving the future of the business in the course of this financial year. Utilisation of complementary skills to maximise value for shareholders and customers National Grid and Lattice share a complementary set of core skills in the development, operation and management of complex networks. Since their privatisations, each of National Grid and Lattice have proven their ability to improve the operating efficiency of their UK regulated businesses. The directors of National Grid and Lattice believe that bringing these businesses together will generate significant opportunities for creating shareholder value through enhanced operating performance and the sharing of best practice, for example between the US and UK businesses. The Merger will provide an opportunity to improve the operation of gas and electricity transmission further, and will allow better overall network planning, which is important in light of increasing interdependence of these systems. Enhanced growth opportunities National Grid has a proven track record in creating material value from expansion in the US and, following a number of acquisitions in recent years, is one of the largest energy delivery companies in the North East US. The US is the world's largest energy market and has proved attractive for expansion due to its fragmented nature and the ability to earn attractive returns within long-term regulatory frameworks. The increased size and financial capacity of the Merged Group combined with expertise in managing both gas and electricity networks should enable it to continue to exploit growth opportunities in the US and those which, over time, are expected to emerge in Europe as the market is liberalised and structural reforms are implemented. Prospects for future outperformance and financial benefits from the Merger The directors of National Grid and Lattice are confident of exceeding their regulatory efficiency targets currently in place, which became effective in April 2001 for National Grid and April 2002 for Transco. National Grid previously announced a target of a 20 per cent. reduction in controllable costs over the remainder of its current price control period. This represented a modest outperformance against Ofgem's targets. National Grid is today announcing that it is now able to increase its target to 30 per cent. which would result in delivery of an additional 80 million pounds sterling savings over the remainder of the period. The Merger will generate pre-tax financial benefits that are expected to reach an annualised rate of at least 100 million pounds sterling by the end of the first full financial year following completion of the Merger. The directors of National Grid and Lattice believe that these financial benefits will arise principally from the elimination of duplicate head office costs and other central cost savings and from combining the support services provided to the UK regulated electricity and gas businesses. Further savings are expected to be achievable from the progressive combination of the operations of the two UK transmission businesses, sharing best practice between the US and UK businesses and further financial synergies. Financial impact The Merger is expected to enhance earnings per share (pre-exceptional items) for both National Grid and Lattice in the first full financial year following completion of the Merger (2). The Merged Group will seek to maintain a single A credit rating. National Grid Transco will have the balance sheet strength and cashflows to facilitate its future growth strategy and underpin its dividend policy which aims to increase dividends per share (expressed in pounds sterling) by 5 per cent. in real terms per annum for each year to 31 March 2006. This will be based on National Grid's full year dividend of 16.04 pence per National Grid Share for the financial year ended 31 March 2002, which includes the recommended National Grid Final Dividend. National Grid Transco will continue to evaluate opportunities to release capital throughout the Merged Group for redeployment in higher growth opportunities, particularly in the US. 3. BOARD OF DIRECTORS, MANAGEMENT AND ORGANISATION The Board of National Grid Transco will be drawn from the Boards of National Grid and Lattice. The Non-Executive Chairman of National Grid Transco will be Sir John Parker, Chairman and acting Chief Executive of Lattice. James Ross, Chairman of National Grid, will be Non-Executive Deputy Chairman. Roger Urwin, Chief Executive of National Grid, will be Chief Executive and Steve Lucas, Finance Director of Lattice, will be Group Finance Director of the Merged Group. In addition to the Chief Executive and Finance Director, the executive management team will comprise Edward Astle, Steven Holliday, Colin Matthews, Rick Sergel and John Wybrew. Stephen Box, National Grid Finance Director, will take early retirement on the grounds of ill-health upon the completion of the Merger. A further six Non-Executive directors will be drawn equally from the Boards of National Grid and Lattice. ----------- (2) The statement that the Merger will be earnings per share enhancing for National Grid and Lattice should not, however, be interpreted to mean that earnings per share in the first full financial year following the Merger, or in any subsequent period, will necessarily be greater than those for the relevant preceding financial period. 4. EMPLOYEES National Grid and Lattice attach great importance to retaining the skills and expertise of their management and employees. The Boards of National Grid and Lattice believe that, although the combination of similar functions will necessarily lead to some staff reductions, the greater strength, market position and growth prospects for the Merged Group will generally enhance career prospects. So far as possible, job losses will be achieved by normal staff turnover, voluntary redundancy and early retirement. The existing employment rights of employees of both National Grid and Lattice will be fully safeguarded. 5. DETAILS OF THE MERGER The terms of the Merger are based on the recent relative equity market capitalisations of the two companies. The Merger is intended to be implemented by way of the Scheme of Arrangement. Under the Scheme, National Grid will issue New National Grid Transco Shares to Lattice Shareholders on the basis of 0.375 New National Grid Transco Shares for each Lattice Share held at the relevant record date, and so in proportion for any other number of Lattice Shares. Upon completion of the Merger, National Grid Shareholders will hold approximately 57.3 per cent. and Lattice Shareholders will hold approximately 42.7 per cent. of the issued share capital of National Grid Transco, based on the current issued share capital of the two companies. If a Lattice Shareholder has a fractional entitlement to New National Grid Transco Shares with a value in excess of 3.00 pounds sterling, such entitlement will be aggregated and sold for the benefit of the relevant Lattice Shareholder. Otherwise, fractions of a New National Grid Transco Share will not be allotted but will be aggregated and sold for the benefit of the Merged Group. The holdings and rights of holders of existing National Grid Shares and of National Grid ADSs will not be affected by the Merger. Under the Scheme, Lattice's current issued share capital will be cancelled and re-issued to National Grid. National Grid will therefore become the listed holding company of the Merged Group and conditional upon the Merger becoming effective will change its name to National Grid Transco and retain its listings on the London and New York Stock Exchanges. The Merger is subject to the conditions and further terms set out in Appendix 1, including the approval of the Merger and related matters by shareholders of both National Grid and Lattice as described below, satisfaction of certain regulatory conditions as described below, and sanction of the Scheme by the Court. The implementation of the Scheme will require approval by a special resolution of Lattice Shareholders to be proposed at the Lattice Extraordinary General Meeting. The Scheme will also require approval separately by Lattice Shareholders at the Lattice Court Meeting. The approval required at the Lattice Court Meeting is a majority in number representing 75 per cent. in nominal value of those Lattice Shareholders who vote at that meeting. The Merger will also require approval by an ordinary resolution of National Grid Shareholders to be proposed at the National Grid Extraordinary General Meeting. Special resolutions to change the name of National Grid to National Grid Transco and to alter its articles of association will also be proposed at the National Grid Extraordinary General Meeting. In order to implement the Merger, the articles of association of National Grid will need to be amended to change the rights of the Secretary of State, principally to reflect National Grid's ownership of Transco. The implementation of the Scheme can only become effective if all the conditions to the Merger have been satisfied or, where relevant, waived. The Scheme will become effective on the delivery to the Registrar of Companies in England and Wales by Lattice of a copy of the order of the Court sanctioning the Scheme and the registration of such order. Once the Scheme becomes effective, the terms will be binding on all Lattice Shareholders whether or not they voted in favour. The formal documentation relating to the Merger is expected to be sent to shareholders by the end of June in order for appropriate resolutions to implement the Merger to be proposed at meetings immediately following Lattice and National Grid's Annual General Meetings on 15 July 2002 and 23 July 2002 respectively. Following receipt of the relevant shareholder, regulatory and Court approvals, it is currently expected that the Scheme will become effective and that the Merger will complete during the autumn of 2002. 6. YEAR END, DIVIDEND PAYMENT AND DIVIDEND POLICY Following completion of the Merger, it is intended that the accounting reference date for National Grid Transco will remain as 31 March. Lattice Shareholders will remain entitled to the second interim dividend of 5.4 pence per Lattice Share, which was declared by Lattice on 7 February 2002 and is due to be paid on 14 June 2002. Lattice will not pay a final dividend in respect of the 15 month period ended 31 March 2002. National Grid Shareholders will have the right to receive the National Grid Final Dividend of 9.58 pence per National Grid Share to be paid on 15 August 2002. New National Grid Transco Shares, issued pursuant to the Merger, will rank pari passu with the existing National Grid Shares save that they will not be entitled to receive the National Grid Final Dividend, or any interim dividend as described below. On completion of the Merger, National Grid Transco intends to pay dividends which reflect National Grid's current dividend policy, which aims to increase dividends per share (expressed in pounds sterling) by 5 per cent. per annum in real terms for each year to 31 March 2006. This will be based on National Grid's full year dividend of 16.04 pence per National Grid Share for the year ended 31 March 2002. It is expected that the first dividend paid by National Grid Transco will be the interim dividend in respect of the financial year ending 31 March 2003. In the event that the Merger does not become effective prior to the announcement of National Grid's interim results for the 6 months to 30 September 2002, it is intended that both companies will announce their interim results and interim dividends on the same day. Lattice Shareholders will be entitled to an interim dividend on the basis that each Lattice Share will be entitled to an amount equal to 37.5 per cent of the declared dividend per National Grid Share for the period. 7. REGULATORY CONSENTS The Merger cannot be completed until a number of conditions have been satisfied, which include the receipt of regulatory and other consents and approvals in the UK and the US, to the satisfaction of National Grid and Lattice. In the UK, the required regulatory approvals include obtaining the consent of the Secretary of State as the holder of the Lattice Special Share and the Secretary of State not referring the Merger to the Competition Commission. The parties will involve Ofgem throughout these processes. In addition, the consent of the Secretary of State will be required under a licence granted to Lattice under the Telecommunications Act 1984. The principal regulatory approval required in the US is approval from the Securities and Exchange Commission under the Public Utility Holding Company Act of 1935 of the issue of the New National Grid Transco Shares to Lattice Shareholders in connection with the Merger. The approval of certain other US regulatory agencies may be required. All such regulations, consents and/or approvals are expected to be received so that completion of the Merger can occur during the autumn of 2002. 8. SETTLEMENT, LISTING AND DEALING Applications will be made to the UK Listing Authority for the New National Grid Transco Shares to be admitted to the Official List and to the London Stock Exchange for such shares to be admitted to trading on the London Stock Exchange's market for listed securities. It is expected that admission will become effective and that dealings, for normal settlement, will commence on the day on which the Scheme becomes effective. National Grid Shareholders who hold their shares in certificated form will retain their existing certificates which will remain valid. New certificates in the name of National Grid Transco will be issued when transfers to persons who wish to hold their National Grid Transco Shares in certificated form are lodged for registration. National Grid ADS holders who hold their ADSs in certificated form will also retain their ADS certificates which will remain valid as ADSs of National Grid Transco. National Grid intends to amend its existing deposit agreement such that, following completion of the Merger, any new certificated ADSs issued and any previously outstanding ADS certificates presented for registration of transfer will be issued in the name of National Grid Transco. Certificates for New National Grid Transco Shares to be issued to Lattice Shareholders pursuant to the Merger are expected to be despatched no later than 14 days after the Scheme becomes effective. No certificates for New National Grid Transco Shares will be issued in respect of the entitlements of Lattice Shareholders who hold their shares through CREST, settlement for which will be made through the applicable CREST procedures. Further details on settlement, listing and dealing will be included in the documents to be sent to National Grid Shareholders and Lattice Shareholders. 9. INTERESTS IN SHARES Neither National Grid nor any director of National Grid, nor, so far as National Grid is aware, any party acting in concert with National Grid, owns or controls any Lattice Shares or any securities convertible or exchangeable into, or any rights to subscribe for or purchase, or any options to purchase any Lattice Shares or holds any derivatives referenced to Lattice Shares. In the interests of confidentiality, National Grid has not made any enquiries in this respect of certain parties who may be presumed by the Panel to be acting in concert with it for the purposes of the Merger. 10. EMPLOYEE SHARE SCHEMES Prior to completion of the Merger, National Grid and Lattice will continue to grant options and awards under their respective employee share schemes in the ordinary course. Appropriate proposals will be made to participants in the Lattice Share Schemes, full details of which will be contained in the documentation to be sent to National Grid and Lattice Shareholders. 11. UNITED KINGDOM AND UNITED STATES TAXATION Subject, where applicable, to receipt of the Inland Revenue clearance under section 138 of the Taxation of Chargeable Gains Act 1992 referred to below, Lattice Shareholders who are resident in the UK for tax purposes will not be treated as making a "disposal" of their Lattice Shares for the purposes of UK capital gains taxation ("CGT") to the extent they receive New National Grid Transco Shares pursuant to the Merger. Instead, Lattice Shareholders will be able to "roll-over" any gain or loss which would otherwise have arisen into the New National Grid Transco Shares which they receive. Lattice Shareholders may realise a disposal for CGT purposes to the extent they receive cash in lieu of fractional entitlements to New National Grid Transco Shares pursuant to the Merger. Applications for clearance in respect of the Merger under section 138 of the Taxation of Chargeable Gains Act 1992 and Section 215 of the Income and Corporation Taxes Act 1998 are being made today. Further details of relevant tax issues will be given in the documents to be despatched to National Grid Shareholders and Lattice Shareholders. The directors of Lattice currently expect that Lattice Shareholders who are US persons who hold Lattice Shares as capital assets generally will not recognise any gain (or loss) for US federal income tax purposes upon the receipt of the New National Grid Transco Shares or the cancellation of the Lattice Shares except to the extent of any cash received in lieu of fractional entitlements. 12. INDUCEMENT FEE As an inducement to both National Grid and Lattice to enter into and implement the Merger, National Grid and Lattice have entered into an agreement. Such agreement provides for either party to pay the other a fee of 60 million pounds sterling if: (i) an announcement is made during the offer period by a third party indicating an intention to make an offer for, or proposal relating to the change of control of, either party, as a result of which either (a) the shareholders of such party do not pass the necessary resolutions approving the Merger, or (b) such party terminates discussions with the other party; or (ii) either party notifies or indicates to the other party that its directors will not unanimously recommend its shareholders to vote in favour of the Merger or the directors of such party do not make such recommendation or withdraw their recommendation or recommend an alternative offer or transaction involving a change of control; or (iii) either party takes any action or omits to take any action (other than as a consequence of a third party regulatory body failing to approve the Merger or placing unacceptable conditions on the Merger in the reasonable opinion of either party) which is reasonably likely to cause the Merger to not become effective, and in each case the Merger does not become effective in accordance with its terms. 13. RECOMMENDATIONS The Board of National Grid, which has been advised by Rothschild, considers the terms of the Merger to be fair and reasonable to National Grid. In providing advice to the National Grid Board, Rothschild has taken into account the National Grid Board's commercial assessments. The National Grid Board considers the Merger to be in the best interests of National Grid Shareholders as a whole and will unanimously recommend National Grid Shareholders to vote in favour of the resolutions to be proposed at the National Grid Extraordinary General Meeting relating to the Merger as they intend to do in respect of their own beneficial holdings. The Lattice Board, which has been so advised by JPMorgan and Cazenove, considers the terms of the Merger to be fair and reasonable to Lattice. In providing advice to the Lattice Board, JPMorgan and Cazenove have taken into account the Lattice Board's commercial assessments. The Lattice Board considers the Merger to be in the best interests of Lattice Shareholders as a whole and will unanimously recommend Lattice Shareholders to vote in favour of the resolutions relating to the Merger to be proposed at the Lattice Court Meeting and the Lattice Extraordinary General Meeting as they intend to do in respect of their own beneficial holdings.

This announcement has been issued by National Grid and Lattice and is the responsibility of National Grid and Lattice and has been approved solely for the purposes of section 21 of the Financial Services and Markets Act 2000 by N M Rothschild and Sons Limited of New Court, St Swithin's Lane, London, EC4P 4DU; J.P. Morgan plc of 125 London Wall, London, EC2Y 5AJ; and Cazenove and Co. Ltd of 12 Tokenhouse Yard, London, EC2R 7AN. The directors of National Grid and the directors of Lattice jointly accept responsibility for the information contained in this announcement other than the information relating solely to National Grid or Lattice and their respective subsidiaries, associates, shareholders and directors, for which the directors of National Grid and Lattice respectively accept such responsibility. To the best of the knowledge, information and belief of such directors (who have taken all reasonable care to ensure that such is the case), the information contained in this announcement for which they accept responsibility is in accordance with the facts and does not omit anything likely to affect the import of such information. National Grid and Lattice have been advised that the New National Grid Transco Shares to be issued under the Scheme are exempt from the registration requirements of the US Securities Act of 1933, as amended and, as a consequence, the New National Grid Transco Shares to be issued under the Scheme will not be registered thereunder. Rothschild is acting exclusively for National Grid and no one else in connection with the Merger and will not be responsible to anyone other than National Grid for providing the protections afforded to customers of Rothschild or for providing advice in relation to the Merger. JPMorgan is acting exclusively for Lattice and no one else in connection with the Merger and will not be responsible to anyone other than Lattice for providing the protections afforded to customers of JPMorgan or for providing advice in relation to the Merger. Cazenove is acting exclusively for Lattice and no one else in connection with the Merger and will not be responsible to anyone other than Lattice for providing the protections afforded to customers of Cazenove or for providing advice in relation to the Merger. Nothing in this announcement should be construed as a profit forecast or be interpreted to mean that the earnings per share of National Grid Transco will necessarily be greater than the historic earnings per share of National Grid or Lattice. Unless otherwise determined by National Grid and Lattice and permitted by applicable law and regulation, the terms of the offer will not be made, directly or indirectly, in or into, or by the use of mails of, or by any other means or instrumentality (including, without limitation, telephonically or electronically) of interstate or foreign commerce of, or of any facility of a national securities exchange of Canada, nor will it be made in or into Australia or Japan. Accordingly, unless otherwise determined by National Grid and Lattice and permitted by applicable law and regulations, neither copies of this announcement nor any other documents relating to the Merger are being, or may be, mailed or otherwise forwarded, distributed or sent in or into Australia, Canada or Japan and persons receiving such documents (including custodians, nominees and trustees) must not distribute or send them in, into or from such jurisdictions. The release, publication or distribution of this announcement in certain jurisdictions may be restricted by law and therefore persons in such jurisdictions into which this announcement is released, published or distributed should inform themselves about and observe such restrictions. This announcement contains certain statements that are neither reported financial results nor other historic information. These statements are "forward-looking statements" within the meaning of the safe-harbour provisions of the US federal securities laws. Because these forward- looking statements are subject to risks and uncertainties, actual future results may differ materially from those expressed in or implied by the statements. Many of these risks and uncertainties relate to factors that are beyond the companies' ability to control or estimate precisely, such as future market conditions, currency fluctuations, the behaviour of other market participants and the actions of governmental regulators. Other factors that could cause actual results to differ materially from those described in this announcement include: the ability to integrate Lattice successfully within National Grid Transco or to realise synergies from such integration or the failure to retain key management and other risk factors detailed in National Grid's reports filed with the SEC or in material furnished to the SEC by National Grid or Lattice. Readers are cautioned not to place undue reliance on these forward- looking statements, which speak only as of the date of this announcement. The companies do not undertake any obligation to publicly release any revisions to these forward-looking statements to reflect events or circumstances after the date of this announcement. The Panel wishes to draw the attention of member firms of the New York Stock Exchange to certain UK dealing disclosure requirements during the offer period. The offer period (in accordance with the City Code, which is published and administered by the Panel) commences at the time when an announcement is made of a proposed or possible offer, with or without terms. National Grid has equity securities traded on the London Stock Exchange and the New York Stock Exchange and Lattice has equity securities traded on the London Stock Exchange. The above disclosure requirements are set out in more detail in Rule 8 of the City Code. In particular, Rule 8 requires public disclosure of dealings during the offer period by persons who own or control, or who would as a result of any transaction own or control, one per cent. or more of any class of relevant securities of the offeror or offeree company. Relevant securities include National Grid Shares, National Grid ADSs, instruments convertible into National Grid Shares or National Grid ADSs, Lattice Shares and instruments convertible into Lattice Shares. This requirement will apply until the end of the offer period. Disclosure should be made on an appropriate form by no later than 12 noon London time on the business day following the date of the dealing transaction. These disclosures should be sent to the Company Announcements Office of the London Stock Exchange (fax number: 44 207 588 6057). The Panel requests that member firms advise those of their clients who wish to deal in the relevant securities of National Grid or Lattice, whether in the United States or in the UK, that they may be affected by these requirements. If there is any doubt as to their application the Panel should be consulted (telephone number: 44 207 382 9026, fax number: 44 207 638 1554).

("Lattice") that the Boards of both companies have unanimously agreed the terms of a recommended merger of equals to form National Grid Transco, National Grid announces: UK Cost Savings At its preliminary results in May 2001, National Grid announced that it would aim to reduce controllable costs in its UK Transmission Owner business by 20per cent in real terms over the term of its price review which ends in March 2006, modestly outperforming the targets set by Ofgem. Following an extensive review of the UK business processes, National Grid is now able to increase this target to 30 per cent delivering a further 80 million pounds sterling of cost savings over the current price review period. Steve Holliday, Group Director Europe said, "This is further proof of our ability to continue to cut costs after the excellent record over the last ten years. I look forward to working with Lattice to exchange best- practice abilities in this area." Board Change The Board announces Stephen Box's intention to retire, through reasons of ill health, as a Director of National Grid on completion of the merger between National Grid and Lattice. James Ross said, "I would like to thank Stephen on behalf of all at National Grid for his enormous contribution to the Group's success. We will be sad to see him leave and we wish him all good fortune on his retirement." Final Dividend The Board is recommending a final dividend of 9.58 pence per share to be paid on 15 August 2002 to shareholders on the register on 7 June 2002. This brings the total dividend for the year to 16.04 pence per share in line with our target to increase dividends by 5 per cent real in each year to March 2006.
