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."

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.

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

National Grid and Lattice have been advised that the New National Grid

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.

of Rothschild or for providing advice in relation to the Merger.

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).

National Grid Announces Cost Savings, Board Change and Final Dividend

Further to today's joint announcement by National Grid Group plc
("National Grid") and Lattice Group plc ("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.


Cautionary statement

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 U.S. 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 the National Grid Group 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.
