                         REPORT OF INDEPENDENT AUDITORS

To: The Board of Directors
    The Energy Group Limited

We have audited the consolidated balance sheets of The Energy Group Limited as
at 31 March 1997 and 1998, and the related consolidated profit and loss accounts
and statements of total recognised gains and losses, cash flows and changes in
invested capital/shareholders' equity for years ended 30 September 1995 and
1996, the six months ended 31 March 1997 and the year ended 31 March 1998. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with United Kingdom auditing standards
which do not differ in any significant respect from United States generally
accepted auditing standards. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis of
our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of The Energy Group
Limited as at 31 March 1997 and 1998 and the consolidated results of its
operations and its consolidated cash flows for the years ended 30 September 1995
and 1996, the six months ended 31 March 1997 and the year ended 31 March 1998 in
conformity with accounting principles generally accepted in the United Kingdom
which differ in certain respects from those generally accepted in the United
States (see Note 33 of Notes to the Financial Statements).

</TABLE>
The cumulative amount of goodwill resulting from acquisitions prior to 31 March
1998, net of goodwill attributable to subsidiary undertakings or businesses
disposed of prior to 31 March 1998, amounted to L.1,201 million derived by
calculating the amount of historical goodwill in the currency of acquisition at
period end rates of exchange. This has been set off against merger reserve and
the net amount reported as other reserves.

Included in the consolidated reserves as at 31 March 1998 was L.3 million in
respect of associated undertakings, all of which arose in the year ended 31
March 1998.

There are no significant statutory or contractual restrictions on the
distribution of current profits of subsidiary or associated undertakings:
undistributed profits of prior years are, in the main, permanently employed in
the businesses of these companies. The undistributed profits of Group companies
overseas may be liable to overseas taxes and/or UK taxation (after allowing for
double taxation relief) if they were to be distributed as dividends.

                        NOTES TO THE FINANCIAL STATEMENTS

1. The Company and Its Capitalisation

The Company was incorporated as a private limited company on 1 October 1996 as
The Energy Group Limited, with an authorised share capital of L. 50,000 divided
into 5,000,000 ordinary shares of 1p each, of which two ordinary shares were
issued to the subscribers fully paid. On 4 December 1996, 4,999,998 of the
authorised but unissued ordinary shares of 1p each were converted into 4,999,998
redeemable preference shares of 1p each (the "Preference Shares") and were
issued on that date at par. On 6 December 1996, the Company was re-registered as
a public limited company under the name The Energy Group PLC. The Preference
Shares were redeemed at par prior to the Demerger using funds contributed to the
Company by Hanson and such shares were re-converted into ordinary shares of 1p
each. On 22 January 1997, the Company's authorised share capital was increased
to L.100,000,000 by the creation of 9,995,000,000 ordinary shares of 1p each.
Upon admission of the Company's ordinary shares to the Official List of the
London Stock Exchange becoming effective ("Admission"), every ten authorised and
issued ordinary shares of 1p each were consolidated into one ordinary share of
10p. 520,857,817 ordinary shares of 10p each were in issue following this
consolidation. A further 18,571 ordinary shares of 10p each were issued during
June 1998 in connection with the satisfaction of rights under the Company's Long
Term Incentive Plan, following the offer by TU Acquisitions being declared
wholly unconditional. As at 7 August 1998, when the Company became a wholly
owned subsidiary of TU Acquisitions, the Company's issued share capital was
520,876,388 ordinary shares of 10p each. On 12 August 1998, the Company was
re-registered as a private limited company.

The Demerger

At the date of the Demerger, Rollalong, a wholly-owned subsidiary of Hanson,
pursuant to an agreement dated 27 January 1997 (the "Demerger Agreement"), owned
or had contracted to acquire, all of the energy-related businesses of Hanson, as
described below.

At various dates between 30 September 1996 and 27 January 1997, various of the
energy-related businesses of Hanson were reorganised under the ownership of
Rollalong. On 24 February 1997, Hanson transferred to the Company the entire
issued share capital of Rollalong, in consideration for which the Company issued
ordinary shares, credited as fully paid, to Hanson shareholders pro rata to
their shareholdings in Hanson, in satisfaction of a dividend in specie declared
by Hanson. Peabody Holding Company, Inc. and its subsidiaries ("Peabody
Holding") were transferred to a subsidiary of Rollalong on 7 March 1997. The
transactions provided for under the Demerger Agreement, including the agreement
for the transfer of Peabody Holding, are together referred to as the "Demerger
Transactions".

The Group

Following completion of the Demerger Transactions, the Company became the
holding company for a group of companies and businesses (together, the "Group")
comprising:

Eastern Group plc and its subsidiaries                         ("Eastern")

Peabody Holding Company, Inc.
Lee Ranch Coal Company                                         ("Peabody")
Peabody Resources Limited (Australia) and its subsidiaries

Rollalong Limited, Consolidated Gold Fields Limited, Major
Insurance Company Limited and various other subsidiaries and   ("infrastructure
intermediate holding companies and non-trading companies         companies")

Citizens Power LLC and its subsidiaries ("Citizens Power") were acquired by the
Group on 19 May 1997.

On 19 May 1998 the Peabody companies, together with Citizens Power, were
disposed of. On the same date the offer by TU Acquisitions for the Company was
declared wholly unconditional. The Financial Statements have been restated to
include the results of the Peabody companies and Citizens Power as discontinued
operations.

2. Basis of Preparation

The financial statements have been prepared to show the performance of the Group
for the three years and six months in the period ended 31 March 1998 as if it
had been in existence from 1 October 1994 as described below. Peabody and the
infrastructure companies were wholly-owned by Hanson throughout that period
until they became part of the Group upon completion of the respective Demerger
Transactions. Eastern was acquired by Hanson on 18 September 1995.

  (i)  The financial statements have been prepared using merger accounting
       principles as if the companies and businesses comprising the Group had
       been part of the Group for all periods presented, or, in the case of
       those acquired or disposed of (other than pursuant to the Demerger
       Transactions) during this period, from or up to the date control passed,
       as appropriate.

       Some individual elements of the reorganisation under Rollalong and of the
       Demerger Transactions were for cash consideration. Such individual
       elements do not satisfy all of the conditions for merger accounting to be
       permitted in accordance with UK financial Reporting Standard 6 and
       Schedule 4A to the Companies Act 1985 (the "Companies Act"), which would
       require such transfers to be accounted for using acquisition accounting
       principles.

       The Directors took account of the continuity of ownership under Hanson of
       all of its energy-related businesses that formed the Group following
       completion of the Demerger Transactions and considered that the Demerger
       Transactions, taken as a whole, required the adoption of merger
       accounting principles in order to show a true and fair view in accordance
       with section 226(5) of the Companies Act.

       The adoption of acquisition accounting principles for some individual
       elements of the reorganisation under Rollalong and of the Demerger
       Transactions would have required: the restatement at fair value of
       certain assets and liabilities transferred; the recognition of goodwill
       which, in some cases, would not be representative of that arising had the
       transfers been conducted at arm's length; and the inclusion of the
       results of certain businesses only from the various arbitrary dates
       chosen for the transfers. As a result of the foregoing, in the opinion of
       the Directors, financial statements using different bases of accounting
       would not give a true and fair view. No quantification has been given of
       the effects of this departure because to do so would be misleading.

 (ii)  Although Eastern was acquired by Hanson on 18 September 1995, its results
       and cash flows have been included in the financial statements based on an
       effective acquisition date of 30 September 1995. The results and cash
       flows for the period 19 to 30 September 1995 are not material.

(iii)  Transactions and balances owing between companies and businesses forming
       part of the Group have been eliminated.

 (iv)  Interest income and expense prior to the Demerger are based on amounts
       recorded in the historical financial returns submitted to Hanson in
       respect of the companies and businesses forming part of the Group. No
       adjustments have been made to reflect the capital structure of the Group
       as it is following the Demerger and, as such, the historical level of
       interest income and expense may not be representative of such amounts
       following the Demerger.

  (v)  Taxation charges and liabilities prior to the Demerger are based on 
       amounts recorded in the historical financial returns submitted to Hanson
       in respect of the companies and businesses forming part of the Group,
       except that adjustments have been made, where appropriate, to provide for
       deferred tax liabilities consequent upon the Group being on a stand-alone
       basis following Demerger. Prior to the Demerger and in previous
       accounting periods, there were various tax-sharing arrangements between
       Hanson, those subsidiaries that form part of the Group and other Hanson
       subsidiaries. These arrangements have had the effect that tax charges
       shown in the financial statements may not be representative of tax
       charges that will be incurred following the Demerger.

The preparation of the financial statements requires management to make
estimates and assumptions that affect the amounts reported. Actual results could
differ from estimates.

<PAGE>   10



3. Principal Accounting Policies

The financial statements have been prepared in accordance with applicable UK
Accounting Standards. The principal accounting policies, which have been applied
consistently for all periods, are set out below.

Accounting convention

The financial statements have been prepared in accordance with the historical
cost convention.

Accounting for acquisitions

Other than in respect of the Demerger Transactions, the results of acquired
companies and businesses are dealt with in the financial statements from the
date of acquisition. On the acquisition of a company or business, fair values
reflecting conditions at the date of acquisition are attributed to the
identifiable tangible assets and liabilities acquired. Where the consideration
paid exceeds the fair value of the net tangible assets acquired, the difference
is treated as goodwill and is set off against reserves in the acquisition
period.

Associated undertakings

Investments which are not subsidiary undertakings and over which the Group
exercises significant influence (other than those which are unincorporated joint
ventures) have been accounted for as associated companies using the equity
method of accounting. Where the Group has an interest in an unincorporated joint
venture or a partnership, such interest has been accounted for as follows:

(i) where all of the venturers share in common the benefits and risks of the
    entire venture, the Group's interest is accounted for using the equity 
    method of accounting;

(ii)where each venturer has its own separate interest in the benefits and risks,
    the Group's interest is accounted for using proportional consolidation on a
    line-by-line basis.

Turnover

Coal sales revenue is recognized at the time of shipment. Electricity and gas
sales include an estimated accrual for the value of electricity and gas consumer
by customers between the date of their last meter reading and the period end.
Turnover is stated exclusive of UK value added tax, but inclusive of related US
coal production duties and UK fossil fuel levy. Turnover includes the revenue
from trading activities.

Tangible Fixed Assets

(a) Capitalisation

Tangible fixed assets are stated at cost or valuation less accumulated
depreciation.

Interest costs relating to the construction or development of production
facilities are capitalized during the pre-production period. Interest costs
incurred after production has commenced are expensed.

Costs incurred to increase the productive capacity of a coal mine or gas field
are capitalized. Costs incurred to maintain the productive capacity of a coal
mine or gas field are expensed.

(b) Depreciation and depletion

Buildings and improvements at coal mines are depreciated over the expected 
productive life of the mine from the date that full production commences.

Depletion of coal and gas reserves is charged on a unit-of-production basis, 
based on an assessment of available and proven reserves respectively.

Freehold land is not depreciated.


                                      F-8
<PAGE>   11



3. Principal Accounting Policies (continued)

Depreciation of assets other than freehold land, coal and gas reserves and
buildings and improvements at coal mines is charged as follows:

<TABLE>
<S>                                                            <C>     
Electricity generating station assets                          30 years

Electricity distribution system assets                         40 years at a rate of 3 per cent per annum for
                                                               first 20 years and 2 per cent per annum for remaining
                                                               20 years

Freehold buildings                                             up to 60 years

Leasehold buildings                                            shorter of 60 years and remaining period of lease

Telecommunications network assets                              10 to 40 years

Plant, equipment and motor vehicles                            2 to 49 years
</TABLE>



 (c) Assets held under leases

Assets held under finance leases are included within fixed assets at the
capitalized value of future minimum lease payments and are depreciated over the
shorter of their lease period and their useful life. The capital element of the
future payments is treated as a liability and the interest element is charged to
the profit and loss account so as to reflect a constant annual rate of interest
on the remaining balance of the outstanding obligation.

Rentals paid on operating leases are charged to the profit and loss account on a
straight line basis over the shorter of the lease period and the useful life of
the leased asset.

(d) Impairment

At each financial year end, an assessment is made of the recoverability of the
balance sheet carrying values of coal and gas assets. This assessment is made
individually at the lowest operational level at which income and cash flows are
monitored as a separate unit. A reduction in carrying value is triggered when
the current book value of such a unit of assets exceeds the undiscounted future
cash flows. Where shortfalls in cash flows compared with carrying values arise,
the assets are written down to fair value, determined usually by discounted
future cash flows generated from the assets.

(e) Reclamation, restoration and abandonment costs

Provision is made for surface reclamation and restoration costs in respect of
coal mines and for abandonment costs in respect of gas fields in accordance with
local conditions and requirements on the basis of costs estimated at the balance
sheet date. The costs are charged to accounting periods on a unit-of-production
basis for gas assets and over the life of the mine for coal.

(f) Environmental costs and obligations

Costs incurred in respect of environmental protection are capitalized if they
provide future economic benefits for the related production facility.
Liabilities for environmental clean-up costs are recognized when clean-ups are
probable and the associated costs can be estimated reasonably.

(g) Customers' contributions

Customer contributions to electricity distribution system assets are credited to
the profit and loss account over a 40-year period at a rate of 3 per cent per
annum for the first 20 years followed by 2 per cent per annum for the following
20 years. The unamortized amount of these contributions is deducted from
tangible fixed assets.

(h) Disposals of fixed assets

HM Government is entitled to a proportion of any gain realised by Eastern
Electricity plc ("Eastern Electricity") on certain property disposals made up to
31 March 2000. A provision for clawback in respect of such disposals is made to
the extent that it is probable that a liability would crystalize. Such a
liability would crystalize when an actual or deemed disposal occurs.

Stocks

Stocks are stated at the lower of cost and net realisable value. Cost includes
labour, supplies, equipment and an appropriate proportion of operating and
overhead costs.


                                      F-9
<PAGE>   12



3. Principal accounting policies (continued)

Investments

Fixed asset investments are stated at cost or Directors' valuation less
provisions for permanent diminutions in value. Current asset investments are
stated at the lower of cost and net realisable value. Investment income is
included in the financial statements of the period to which it relates.

Foreign currencies

Average rates of exchange ruling during the period are used to translate the
profit and loss accounts of overseas subsidiary and associated undertakings. The
balance sheets of overseas subsidiary undertakings are translated at rates
ruling at the balance sheet date. Differences on translation arising from
changes in the sterling value of overseas net assets, together with the
differences between profit and loss accounts translated at average rates and at
balance sheet rates, are shown as a movement on reserves and in the statement of
recognized gains and losses. Exchange gains and losses arising on long-term
foreign currency borrowings used to finance the Group's foreign currency
investments are also dealt with in reserves. Other exchange rate differences are
dealt with in the profit and loss account for the period.

Deferred taxation

Deferred taxation is provided on the liability method in respect of timing
differences except where the liability or asset is not expected to crystalize in
the foreseeable future. No deferred tax asset is recognized corresponding to
liabilities provided for in respect of post-retirement healthcare benefits.
Provision is not made for additional taxation which might be payable if profits
retained by overseas companies were distributed as dividends.

Healthcare and other obligations to employees

During the year, the Group provided healthcare and other benefits, including
workers' compensation benefits, to certain qualifying employees and former
employees of the Peabody companies and their dependants under the provisions of
various benefit plans or as required by US State or federal law. These benefits
are accrued and charged to the profit and loss account over the expected service
lives of the employees with the exception of pneumoconiosis (black lung)
benefits in respect of employees ceasing employment prior to 1 July 1973, which
are accounted for as payments are made. Pneumoconiosis benefits in respect of
employees ceasing employment after 30 June 1973 are estimated actuarially; the
last actuarial review was performed as at 1 October 1996.
Other workers' compensation benefits are also assessed actuarially.

Pension costs

The Group operates retirement benefit schemes in the UK and, during the year,
the US and Australia, in accordance with local regulations and custom. The
assets of the schemes are held in separate funds administered by trustees.

The costs of providing pensions are charged to the profit and loss account over
employees' service lives. The pension costs relating to those schemes which
provide defined benefits are assessed in accordance with the advice of qualified
actuaries.

Derivative financial instruments

The group defers the effect of changes in the market value of derivative
financial instruments (including contracts for differences and electricity
forward agreements) which are used to hedge future transactions to the period
when the related transaction is completed. The group considers its net open
energy trading position, including derivative financial instruments entered into
as part of the group's energy trading activity, and provides for any anticipated
future losses.

Contract restructuring activities

Assets and liabilities associated with contract restructuring activities are
marked to market. Movements in the market value are recognized in the profit and
loss account in the period of change. In the absence of a readily available
market price, fair value based on discounted cash flows is used.

account.

During the six months ended 31 March 1997, a Group undertaking sold a coal
supply agreement to an unrelated third party in exchange for an initial L.7
million payment, and nominal future consideration, which resulted in a gain of
L.7 million. This amount was included in "Turnover - discontinued operations" in
the consolidated profit and loss account.

During the year ended 30 September 1996, a Group undertaking agreed to terminate
a coal supply agreement in exchange for a L.14 million payment from a customer
which resulted in a gain of L.14 million. This amount was included in "Turnover
- - discontinued operations" in the consolidated profit and loss account.

During the year ended 30 September 1995, a Group undertaking agreed to terminate
a coal supply agreement in exchange for a L.16 million payment from a customer.

terminating a related coal purchase agreement as well as certain other costs
related to the transaction. The gain was included in "Turnover - discontinued
operations" in the consolidated profit and loss account.

6. Costs and overheads less other income (continued)

The reorganization provision created on the acquisition of Eastern in 1995 of

respect of this provision, was also reversed in 1996.

Other operating charges less other income for the year ended 31 March 1998
includes operating lease rentals payable of L.287 million (six months ended 31
March 1997: L.138 million, years ended 30 September 1996: L.77 million, 1995:
L.20 million) primarily in respect of plant and machinery.

8. Exceptional items

During 1996, the Group received an interim dividend of L.11 million and special
dividends (net of associated costs) totalling L.165 million connected with the
flotation of The National Grid Group plc ("National Grid Group"). Amounts
credited to electricity customers in the form of a discount on electricity bills
connected with this flotation totalled L.132 million.

The profit on disposal of First Hydro of L.25 million in 1996 arose on the
disposal of the Group's interest in the pumped storage business of National Grid
Group.


9. Net interest

Prior to the Demerger, a significant proportion of the Group's cash and bank
balances and borrowing requirements were transferred to, or provided by, the
Hanson group. No interest was received or paid on the amounts so transferred or
provided.

10. Taxation charge/(credit) (continued)

If full provision had been made for deferred tax for the year ended 31 March
1998, the tax charge would have increased by L.1 million (six months ended 31
March 1997 decreased by L.71 million, year ended 30 September 1996 increased by
L.31 million, 1995 L.nil). As a result of the stand-alone basis of providing for
deferred tax, the charge for deferred tax shown above was increased by L.57
million for the year ended 30 September 1996 (1995 L.42 million).

As a result of the surrender of group relief for nil consideration, together
with the taxation effects of the National Grid Group flotation, the tax charge
shown for the two years ended 30 September 1996 is not representative of the
charge that may arise following the Demerger Transactions.

A reconciliation of the tax charge at the UK statutory rate of corporation tax
to the actual tax charge is as follows:

11. Earnings per share

Earnings per share are based on the profit for each period and on 521 million
ordinary shares for each of the two years in the period ended 30 September 1996,
being the number of ordinary shares in the Company which were issued in respect
of the Demerger.

Earnings per share for the six months ended 31 March 1997 are based on 519
million ordinary shares. This excludes the 2 million shares held as at 31 March
1997 by The Energy Group Employee Benefit Trust which had waived its right to
dividends on the shares it held.

Earnings per share for the year ended 31 March 1998 are based on 517 million
ordinary shares. This excludes the 4 million shares held as at 31 March 1998 by
The Energy Group Employee Benefit Trust which had waived its right
to dividends on the shares it held.

The numbers of shares used for the calculation of undiluted and diluted earnings
per share are as follows:

11. Earnings per share (continued)

Adjusted earnings per share figures are based on the profit for the relevant
period after excluding the items relating to the National Grid Group flotation,
the profit on disposal of First Hydro, the exceptional restructuring,
reorganisation and bid-related costs and related taxation, and the windfall tax
as follows:

The interest expense prior to the Demerger was affected significantly by the
financing arrangements of Hanson. Accordingly the allocation of interest expense
between continuing and discontinued operations for periods ending on or before
30 September 1996 is not considered meaningful. Consequently the analyses of
earnings and earnings per share are only presented here for the six months ended
31 March 1997 and the year ended 31 March 1998.

Earnings per share figures for the six months ended 31 March 1997 and the year
ended 31 March 1998 can be broken into continuing and discontinued operations as

The investment in own shares represents The Energy Group Employee Benefit
Trust's investment in the Company's shares.

The Energy Group Employee Benefit Trust ("the Trust") was established to acquire
ordinary shares in the Company, by subscription or purchase, with funds provided
by the Company to satisfy rights to shares arising on the exercise of share
options and on the vesting of performance-related share awards. At 31 March 1998
the Trust had acquired 4,063,338 ordinary shares at a cost of L.19.8 million
(1997: 2,250,000 ordinary shares at a cost of L.10.7 million), financed by
interest-free loans from the Company, which at the balance sheet date totalled
L.19.8 million. The Trust waived its right to dividends on the ordinary shares
held by it.

Since 31 March 1998 the Trust has sold 1,296,308 of the shares held by it to
Energy Trustees Limited, a wholly owned subsidiary of the Company, which acted
as trustee of a Qualifying Employee Share Ownership Trust, such trust being
established to satisfy rights under the Group's Savings Related Share Option
("Sharesave") Scheme. The proceeds of such sale (L.10.9 million) were used by
the Trust to reduce the amount of the interest-free loans from the Company. The
remainder of the shares held by the Trust were either assented to the offer by
TU Acquisitions (the proceeds being used in part to repay the balance of the
interest-free loans from the Company, in part to grant replacement deferred
bonus awards and in part to satisfy cash cancellation payments to participants
in various Company employee share plans, following the change in control of the
Company) or transferred to (or assented to the TU Acquisitions offer for the
Company on behalf of) participants in such schemes upon exercise of their rights
under the schemes.

The principal associated undertaking at 31 March 1998 was:

</TABLE>
The cumulative amount of goodwill resulting from acquisitions prior to 31 March
1998, net of goodwill attributable to subsidiary undertakings or businesses
disposed of prior to 31 March 1998, amounted to L.1,201 million (1997: L.1,147
million). This has been derived by calculating the amount of historical goodwill
in the currency of acquisition at period end rates of exchange. This has been
set off against merger reserve and the net amount reported as other reserves.

Pro forma invested capital reflects the figures included within the company's
Listing Particulars issued in January 1997.

Prior to demerger the Group's capital structure consisted entirely of invested
capital. A reconciliation of the movements in invested capital for each of the
two years ended 30 September 1996 is shown on page F-5.


23. Acquisitions

On 20 May 1997 the Group acquired Citizens Lehman Power L.L.C. which was renamed
Citizens Power LLC. Citizens Power provides contract restructuring services to
the energy industry. The acquisition involved an initial payment of L.12.5
million in cash, plus a payment deferred until 31 March 2000, equivalent to the
net assets at 30 June 1997. There was to be additional purchase consideration
linked to profit goals up to 2002, subject to a maximum consideration for the
entire transaction of $120 million (but this obligation has been assumed by the
purchaser of Citizens Power following its disposal as described below). For the
period since acquisition, turnover of L.28 million and operating profit of L.18
million in respect of Citizens Power are included within the consolidated profit
and loss account. Citizens Power's operating assets and liabilities were as
follows:

23. Acquisitions (continued)

Fair value adjustments were made to the book value of the assets and liabilities
of the above acquisition to bring them into line with the company's accounting
policies and to adjust where applicable the carrying values of certain assets
and liabilities.

For the year prior to acquisition, Citizens Power reported profit after tax of
L.3 million.

Citizens Power was disposed of on 19 May 1998 and therefore has been disclosed
within discontinued operations.

During the six months ended 31 March 1997 the Group acquired 52.8 per cent of
the issued share capital of Teplarny Brno a.s.("Telparny Brno"), a heating and
generation company based in the Czech Republic. For the period from acquisition
to 31 March 1997, turnover of L.18 million and operating profit of L.3 million
in respect of this acquisition are included within the consolidated profit and
loss account. The total purchase consideration for the acquisition of this 52.8
per cent interest was L.21 million. Its operating assets and liabilities were as
follows:

Fair value adjustments were made to the book value of the assets and liabilities
of the above acquisition to bring them into alignment with the Group's
accounting policies and to adjust where applicable the carrying values of
certain assets and liabilities.

For the year prior to acquisition. Teplarny Brno reported profit after tax of
L.4 million. A further 31% of Teplarny Brno was acquired during the year ended
31 March 1998 for cash consideration of L.7 million.

There were no significant acquisitions in the year ended 30 September 1996.

Goodwill arising at the time of acquisition of Eastern of L.1,368 million was
reduced in 1996 by L.221 million, principally as a result of the release of
provisions no longer considered necessary.

years in which they were actually made and at the beginning of the respective
previous years, the unaudited pro forma results of operations of the Group would

The acquisitions of Citizens Power and Teplarny Brno would not have had a
material impact on the Group's results prior to acquisition.


24. Contingent liabilities

Certain properties in the US in which the Group had an interest at 31 March 1998
are subject to actual or potential environmental claims. The companies which had
interests in these properties were sold on 19 May 1998.

In February 1997 final determinations were made against The National Grid
Company plc ("National Grid") and its group trustees by the Pensions Ombudsman
on complaints by two pensioners in National Grid's section of the Electricity
Supply Pension Scheme ("ESPS") relating to the use of the surplus arising under
the actuarial valuation of the National Grid section as at 31 March 1992 to meet
certain additional costs arising from the payment of pensions on early
retirement pursuant to reorganization or redundancy and certain additional
contributions. These determinations were set aside by the High Court on 10 June
1997 and the arrangements made by National Grid and its trustees in dealing with
its section's surplus were confirmed. The two pensioners have now appealed
against this decision. This appeal is unlikely to be heard until 1999. If a
similar complaint were to be made against Eastern in relation to its use of
actuarial surplus in its section of the ESPS, it would resist it, ultimately
through the courts. However, if a determination were finally to be made against
it and upheld by the courts, Eastern could have a potential liability to repay
to its section of the ESPS an amount estimated by the Directors to be up to L.90
million (exclusive of any applicable interest charges).

The Group is subject to business risks which are actively managed against
exposures.


25. Financial commitments

(a) Capital commitments of the Group were as follows:

</TABLE>

(b) Gas take or pay contracts

There are various types of contracts for the purchase of gas. Almost all include
"take or pay" obligations under which the buyer agrees to pay for a minimum
quantity of gas in a year. In order to help meet the expected needs of its
wholesale and retail customers, Eastern has entered into a range of gas purchase
contracts. As at 31 March 1998 the commitments under long-term gas purchase
contracts amounted to an estimated L.2.8 billion (1997: L.2.2 billion) covering
periods up to 18 years forward. The Directors do not consider it likely, on the
basis of the Group's current expectations of demand from its customers as
compared with its take or pay obligations under such purchase contracts, that
any material payments will become due from the Group for gas not taken.

The majority of the operating lease commitments relate to coal-fired power
stations. Additional payments of approximately L.6 per megawatt hour (indexed)
linked to output levels from these stations are payable for between the first
five and seven years of their operation by the Group.

26. Pension and post-retirement healthcare

Pensions
The Group participates in several defined benefit pension plans in the UK, and,
during the year, the US and Australia which cover the majority of employees. The
benefits for these plans are based primarily on years of credited service and
final average pensionable pay as defined under the respective plan provisions.

The total cost of all pensions of the Group in the years ended 30 September 1995
and 1996, the six months ended 31 March 1997 and the year ended 31 March 1998,
was L.13 million, L.17 million, L.10 million and L.16 million, respectively. The
amount for 1996 includes L.4 million relating to UK employees and L.10 million
in respect of additional one-off cash retirement costs for US employees.

In the US, Peabody sponsored four main defined benefit pension plans. With the
exception of one plan, assets were set aside in separate trustee-administered
funds. Each of these plans was assessed annually by independent qualified
actuaries using the projected unit method, the latest valuations being as at 30
September 1996. In addition, Peabody participated in two multi-employer plans.
In these plans, the assets contributed by the participating employers were
aggregated and the contributions payable are determined by independent qualified
actuaries in accordance with industry-wide agreements. Peabody also had a number
of defined contribution plans. Costs relating to the multi-employer and the
defined contribution plans were recognized as incurred. As stated elsewhere in
this report, Peabody was disposed of on 19 May 1998.

26. Pension and post-retirement healthcare (continued)

In the UK, the majority of Eastern employees are members of the ESPS which
provides pensions of a defined benefit nature for employees throughout the
Electricity Supply Industry. The ESPS operates on the basis that there is no
cross-subsidy between employers and the financing of Eastern's pension
liabilities is therefore independent of the experience of other participating
employers. The assets of the ESPS are held in a separate trustee-administered
fund.

The pension cost relating to the Eastern part of the ESPS is assessed in
accordance with the advice of independent qualified actuaries using the
projected unit method. The latest actuarial valuation was carried out
as at 31 March 1995.

The total market value of the assets of the US plans, excluding the
multi-employer and defined contribution plans, was L.255 million as at 30
September 1996. The market value of the assets of Eastern's section of the ESPS
was L.681 million at 31 March 1995.

The assumptions which had the most significant effect on the results of the
valuations were that the rate of investment return would exceed salary increases
(exclusive of merit awards) by 2 1/2 per cent per annum for the UK plans and by
an average 3 1/2 per cent per annum in the US, and with investment returns in
the UK being assumed to exceed future pension increases by 4 per cent per annum.
The actuarial value of the assets was sufficient to cover 104 per cent of the
benefits that had accrued to members in the UK and 98 per cent in the US.

Provisions for liabilities and charges (Note 20) include a provision of L.8
million (provision of L.10 million at 30 September 1995, prepayment of L.1
million at 30 September 1996, and provision of L.4 million at 31 March 1997)
representing the excess of the accumulated amount charged against the Group's
profits in respect of pension costs over the contributions paid to the plans
concerned.

Post-Retirement Healthcare

Until the disposal of Peabody, the Group also provided during the year,
post-retirement health care and life assurance benefits under plans mainly in
the US to certain groups of its retired and active employees.

As at 31 March 1998 the accumulated post-retirement benefit obligation excluding
pensions, as assessed by independent qualified actuaries, for retirees and the
obligation for prior service costs of currently active employees is
approximately L.582 million (1997: L.576 million). The charge for the year ended
31 March 1998 has been accrued based upon actuarial calculations determined in
accordance with required accounting standards. This resulted in the recognition
of service costs for benefits earned during the period of approximately L.4
million (six months ended 31 March 1997: L.2 million), and interest cost on
accumulated benefit obligations of approximately L.42 million (six months ended
31 March 1997: L.2 million). The actuarial assumptions used to estimate the
obligations vary according to the claims experience and economic conditions
relevant to each plan. It has been assumed that the annual per capita cost of
benefits will increase 6-8 per cent depending on claims experience and economic
conditions relevant to each plan. This rate is assumed to decrease to 5 per cent
over 5 years. The weighted average discount rate used in determining the
accumulated post-retirement benefit obligation was 7 1/2 per cent as at 31 March
1998.

31. Related party transactions

A company which was a subsidiary of the Group as at 31 March 1998 has purchased
coal from Black Beauty Coal Company, a partnership in which the Group had a 43
per cent investment at 31 March 1998. The subsidiary purchased 126,601 tons (six
months ended 31 March 1997: 37,645 tons) of coal at a cost of approximately L.2
million during the year ended 31 March 1998 (six months ended 31 March 1997: L.1
million). The subsidiary concerned was disposed of by the Group on 19 May 1998
along with the rest of its Coal interests.

Prior to the Demerger, the Group did not operate as a separate group, and
consequently there were a number of related party transactions between it and
Hanson. These include transactions in respect of treasury, insurance, taxation
and other central services supplied by Hanson to the Group. These transactions
have not been identified individually as it is not practical to do so.

31. Related party transactions (continued)

Hanson has agreed to provide the Group with business development and consultancy
services in the Far East for a period of three years following the Demerger. The
amounts payable for these services are not material.



32. Employee share plans

The Group had the following employee share plans as at 31 March 1998:

(a) The Energy Group Sharesave Scheme which was available to the UK based
    employees of participating companies within the Group and those directors
    who were employees of participating companies and who devoted more than 25
    hours a week to their duties. Employees who participated in this scheme had
    to enter into a monthly savings contract.

(b) The Energy Group Executive Share Option Scheme which was administered by the
    Remuneration Committee of the Board of Directors of the Company ("the
    Remuneration Committee") and was available at its discretion to employees of
    the Group and those directors (other than Directors of the Company) who
    devote more than 25 hours a week to their duties.

(c) The Energy Group Long-term Incentive Plan operated in conjunction with the
    Company's Employee Benefit Trust. The Plan was supervised and administered
    by the Remuneration Committee. The Plan could be made available to all
    employees and directors of the Group at the discretion of the Remuneration
    Committee, but it was in practice limited to the executive directors of the
    Company and certain senior executives of the Group. A "phantom" Long Term
    Incentive Plan was also put in place at Citizens Power LLC upon its
    acquisition by the Group.

(d) The Energy Group Employee Benefit Trust was for the benefit of employees,
    ex-employees and the spouses and dependants of such employees or
    ex-employees of the Group. The purpose of the Trust was to facilitate and
    encourage ownership of the Company's shares.

(e) The Peabody Plans were voluntary plans open to all applicable US based
    employees of Peabody (one plan was also open to hourly paid employees).

The movements in share options outstanding during the year ended 31 March 1998
were:

The options listed above were all granted between 25 February and 31 March 1997.

No options lapsed or were exercised prior to 31 March 1997.

Since 31 March 1998 all options or awards then outstanding under the employee
share plans described in (a) to (c) above have, as a consequence of the takeover
of the Company by the Texas Utilities group, either been exercised, waived or
surrendered for a cash cancellation payment or lapsed.

33. Differences between UK GAAP and US GAAP

The financial statements have been prepared under UK GAAP which differ in
certain respects from US GAAP.

The following is a summary of the principal differences between UK GAAP and US
GAAP that are significant to the Group and adjustments to profit for the year
and equity shareholders' funds (shareholders' equity reserves) which would be
required if the financial statements were to be restated under US GAAP.

Goodwill

Under UK GAAP, goodwill arising on the acquisition of a subsidiary is set off
against reserves in the year in which that subsidiary is acquired. Under US
GAAP, such goodwill is capitalized and amortized through the profit and loss
account over its estimated useful life, not exceeding 40 years. For the purposes
of the reconciliations set out below, an estimated useful life of 25 years has
been adopted. Under UK GAAP, the gain or loss on the sale of a subsidiary
includes any goodwill previously set off against reserves. Under US GAAP, such
gain or loss includes any unamortized goodwill relating thereto. For US GAAP
purposes, the carrying amount of goodwill is periodically compared with future
potential cash flows over the remaining amortization period.

Taxation

Under UK GAAP, deferred tax is provided using the liability method for all
timing differences to the extent that it is probable that the liability will
crystalize in the foreseeable future. US GAAP require deferred taxation to be
provided in full, using the liability method on all temporary differences
between the tax and book bases of assets and liabilities.

Under US GAAP, valuation allowances with respect to deferred tax assets are
provided when it is considered more likely than not that all or a portion of the
deferred tax assets will not be realized. As discussed in Note 10, the tax borne
by the Group may not be representative of the charges it will incur following
Demerger and thus differs from the amount the Group in the two years ended 30
September 1996 would have borne as a stand-alone entity. US GAAP require taxes
to be allocated among the members of a group if they prepare separate financial
statements.

Pension plans

Under both UK GAAP and US GAAP, the cost of providing pensions under the Group's
defined benefit schemes is charged to the consolidated profit and loss account
over the employees' service lives. US GAAP require that the projected benefit
obligations be matched against the fair value of the schemes' assets and that
adjustments be made to reflect any unrecognized obligations or assets in
determining the pension cost or credit for the period. US GAAP also prescribe
the basis for determining curtailment costs. In connection with the acquisition
of Eastern, under US GAAP, a prepaid pension cost of L.119 million, equal to the
excess of Eastern's pension scheme assets over the related projected benefit
obligation at 30 September 1995, has been recognized.

Provision for restructuring and reorganisation

Under UK GAAP, the Group charged L.25 million against profit in the year ended
31 March 1998 (L.20 million in the six months ended 31 March 1997 and L.29
million in the year ended 30 September 1995) in relation to provisions for
restructuring and reorganisation. Under US GAAP these provisions would only have
been permitted in the year ended 31 March 1998. The 1997 provision was utilised
during the year ended 31 March 1998. Under US GAAP this would be charged against
profit in the latter year. The 1995 provision was reversed under UK GAAP in the
year ended 30 September 1996 as it was no longer required. Accordingly, under US
GAAP, this reversal has been removed in the reconciliation below.

Impairment of Long-lived Assets

The Group's accounting policy for impairment of long-lived assets was adopted
for the first time in the year ended 30 September 1996. This policy accords with
the requirements of Statement of Financial Accounting Standards ("SFAS") No.
121. Under UK GAAP, the change in accounting policy has been treated as a prior
year adjustment and, accordingly, the financial statements have been presented
on the basis of the revised policy with the effect of the change on prior years
reflected in invested capital at 1 October 1993. Under US GAAP, impairment
losses resulting from the application of SFAS 121 to assets to be held and used
are reported in the period in which the recognition criteria are first applied
and met as a component of continuing operations.

Subordinated income note

Under UK GAAP, the 5 per cent subordinated income note 2006 is recorded at its
nominal amount. Under US GAAP, this income note has been discounted at a rate of
13 per cent per annum.

Dividend

Under UK GAAP, dividends and the related Advance Corporation Tax ("ACT") are
recorded in the financial statements for the period to which they relate. Under
US GAAP, dividends and related ACT are not recorded until the dividends are
declared.

33. Differences between UK GAAP and US GAAP (continued)

Exceptional items

Under UK GAAP, the exceptional effects of the flotation of National Grid Group
have been shown separately in the consolidated profit and loss account and
operating profit and earnings per ordinary share are disclosed both before and
after this effect. Further, the gain on sale of First Hydro is reported as a
non-operating exceptional item after operating profit. Under US GAAP, the gain
on sale of First Hydro would have been included in the determination of
operating profit and disclosure of operating profit and earnings per ordinary
share before and after exceptional items is not permitted.

Output-linked lease payments

Under UK GAAP, the output-linked operating lease payments are charged to the
consolidated profit and loss account over the estimated useful lives of the
related power stations, which exceed the payment periods involved. Under US
GAAP, such payments are considered as contingent rental payments and therefore
are charged as incurred. The amounts shown for 31 March 1997 along with the
related deferred tax effects, have been restated. Previously, no adjustment was
made for such difference between UK and US GAAP.

Customer acquisition costs

Under UK GAAP certain costs associated with acquiring customers in the newly
deregulated gas market are capitalized until the commencement of the relevant
customers' contracts, at which time the costs are charged in full against
profits. Under US GAAP such costs are not able to be capitalized. Accordingly,
the costs capitalized under UK GAAP at 31 March 1998 have been charged to the
profit and loss account for US GAAP.

A reconciliation between the number of shares used in calculating basic and
diluted per ordinary share amounts is shown in note 11.

The interest expense prior to the Demerger was affected significantly by the
financing arrangements of Hanson. Accordingly the allocation of interest expense
between continuing and discontinued operations for periods ending on or before
30 September 1996 is not considered meaningful. Consequently the analyses of
earnings and earnings per share into continuing and discontinued operations are
only presented here for the six months ended 31 March 1997 and the year ended 31
March 1998.

Consolidated Cash Flow Statement

The consolidated statements of cash flows present substantially the same
information as that required under US GAAP. UK GAAP and US GAAP differ, however,
with regard to classification of items within the statements and as regards the
definition of cash and cash equivalents.

In 1996 the UK Accounting Standards Board revised the UK Financial Reporting
Standard No. 1, "Cash Flow Statements". The consolidated cash flow statements
for the year ended 31 March 1998 and for the six months ended 31 March 1997 set
out on page F-4 have been prepared in conformity with the revised standard and
prior years have been restated to conform with the new presentation. The
principal differences between this statement and cash flow statements presented
in accordance with US GAAP are as follows:

1.  Under UK GAAP, net cash flow from operating activities is determined before
    considering cash flows from (a) returns on investments and servicing of
    finance and (b) taxes paid. Under US GAAP, net cash flow from operating
    activities is determined after these items.

2.  Under UK GAAP, capital expenditure is classified separately, while under US
    GAAP, it is classified as an investing activity.

3.  Under UK GAAP, dividends are classified separately, while under US GAAP,
    dividends are classified as financing activities.

4.  Under UK GAAP, movements in short-term investments are not included in cash,
    but classified as management of liquid resources. Under US GAAP, short-term
    investments with a maturity of three months or less at the date
    of acquisition are included in cash.

The categories of cash flow activity under US GAAP can be summarized as follows:

The interest expense prior to the Demerger was affected significantly by the
financing arrangements of Hanson. Accordingly the allocation of interest expense
between the United Kingdom and Other for periods ending on or before 30
September 1996 is not considered meaningful. Consequently the analysis of profit
before taxation is only represented here for the year ended 31 March 1998 and
for the six months ended 31 March 1997.

Contracts for differences and electricity forward agreements

Almost all electricity generated in England and Wales must be sold to the Pool,
and electricity suppliers must likewise generally buy electricity from the Pool
for resale to their customers. The Pool is operated under a Pooling and
Settlement Agreement to which all licensed generators and suppliers of
electricity in Great Britain are party.

Eastern utilizes contracts for differences ("CfDs") and electricity forward
agreements ("EFAs") to manage its net exposure to fluctuations in electricity
pool prices. CfDs and EFAs are contracts which fix the price of electricity for
an agreed quantity and duration by reference to an agreed strike price. EFAs are
similar in nature to CfDs, except that they tend to last for shorter time
periods and are based on standard industry terms rather than being individually
negotiated. Long-term CfDs are in place to hedge a proportion of electricity
purchases up to 2009. From 1998 such CfDs represent an annual commitment of
approximately five terawatt hours ("TWh"), falling on a linear basis to
approximately two TWh by 2005 and finally expiring in 2010. There are no similar
long-term commitments under EFAs.

33. Differences between UK GAAP and US GAAP (continued)

Estimates of the fair value of these contracts would be based upon assumptions
of a number of complex factors, in particular the anticipated long-term level of
Pool prices and appropriate market discount rates. It is not possible to
estimate the long-term level of Pool prices with reasonable accuracy because of
their inherent volatility. In addition, there is no readily identifiable market
through which they could be realised in an exchange. In view of the foregoing,
it is not practicable to ascribe a fair value to these contracts.

Approximately 38 per cent by volume of all of the Group's CfDs and EFAs in the
year ended 31 March 1998 were contracted with National Power plc and PowerGen
plc (six months ended 31 March 1997: 60 per cent).

Interest rate swaps

Interest rate swaps are used by the Group to convert fixed into floating rate
debt. The Group is exposed to credit loss in the event of non-performance by the
counterparties to the interest rate swaps. This exposure is managed by selecting
counterparties based on their credit ratings and by monitoring total exposure to
each counterparty. See Note 19.

Fair value of financial instruments

US GAAP require the disclosure of estimated fair values for all financial and
derivative financial instruments for which it is practicable to estimate that
value. The carrying amounts and fair values of the material financial
instruments of the Group are as follows:

The following methods and assumptions were used to determine the above fair
values:

(i)      Because of the unusual and specific nature of the fixed asset
         investments it is not considered practicable to estimate their fair
         value;

(ii)     The carrying amounts of current asset investments, short-term deposits
         and cash approximate their fair value;

(iii)    The fair value of the 5 per cent subordinated income note 2006 is based
         on estimated borrowing rates used to discount the cash flows to their
         present value. The fair value of the investment bonds is based on their
         quoted mid-market prices and excludes the value of the interest rate
         swaps; and

(iv)     The fair value of the interest rate swaps is based on the cancellation
         value of each swap quoted by the relevant bank counterparty.

The following table sets forth the funded status and amounts recognized in the
combined balance sheet at 31 March 1998 and 1997 for the Group's defined benefit
pension plans excluding multi-employer plans. Of the total amounts of assets
shown in the note, approximately 25 per cent applies to US defined benefit
plans.

Under purchase accounting, a fair value adjustment of L.119 million, equal to
the excess of Eastern's pension plan assets over the projected benefit
obligation, was included as a prepaid pension cost under US GAAP at 30 September
1995.

Post-retirement healthcare

The Group also provides post-retirement healthcare and life insurance benefits
under plans mainly in the US to certain groups of its retired and active
employees:

</TABLE>

The health care cost trend rate assumption has a significant effect on the
amounts reported. Increasing the assumed health care cost trend rates one
percentage point in each year would increase the accumulated post-retirement
benefit obligation as of 31 March 1998 by L.74.0 million (1997: L.73.0 million).
The effect of this change on the aggregate of the service cost and interest cost
components of net periodic post-retirement benefit costs for the year ended 31
March 1998 would be an increase of L.7.0 million (six months ended 31 March
1997: L.3.5 million).

The post-retirement benefit cost included the following components:

Additional information about impairment of long-lived assets required by US GAAP

SFAS 121 requires impairment losses to be recognized on long-lived assets used
in operations when indicators of impairment are present and the undiscounted
cash flows estimated to be generated under various assumptions by those assets
are less than the assets' carrying amount. Impairment losses under SFAS 121 are
measured by comparing the estimated fair value of the assets to their carrying
amount.

During the course of its financial year ended 30 September 1996. Hanson
commissioned independent valuations of each of its principal operating
businesses in connection with formulating its plans for their possible demerger.
These indicated, Inter alia, possible impairment in certain of the Group's US
coal assets, arising from the cumulative effects of the Clean Air Amendments Act
1990 and weak demand and lower prices in certain markets. As a result, a
detailed evaluation of the Group's US coal assets was undertaken in accordance
with the principles laid down by SFAS 121.

Under US GAAP, a non-cash charge of L.578 million would be recorded in the year
ended 30 September 1996 as a result of adopting the evaluation methodology of
SFAS 121, principally related to impairment of certain inactive and undeveloped
coal reserves.

Under US GAAP, prior to the adoption of SFAS 121, asset impairment was evaluated
at an operating company level based on the contribution of operating profits and
undiscounted cash flows being generated from those operations. Under the Group's
previous policy, assets used in operations, which consisted of multiple
operating companies, were evaluated for impairment based on gross margins and
cash flows generated by each separate operating company in a given business
cycle. No reduction in carrying value was required since, on that basis,
earnings and cash flows indicated no impairment in asset value.

SFAS 121 requires the impairment review to be performed at the lowest level of
asset grouping for which there are identifiable cash flows, a change from the
higher level at which the Group's previous accounting policy measured
impairment. The Group's economic grouping of assets was based on the markets in
which the operations compete, and in the coal segment consisted of both active
and inactive mines, as well as undeveloped properties. Evaluation of assets at
the lower grouping level indicated an impairment of certain of those assets.
This policy does not allow off-setting of surpluses from assets whose future
cash flows exceed current book values. Where shortfalls in cash flows compared
to carrying values arise, the assets are written down to fair value, determined
by discounted future cash flows from the assets or estimated current market
values.

Concentration of credit risk

The Directors did not consider there to be any significant concentration of
credit risk as at 31 March 1998.

Impact of new accounting standards

The Financial Accounting Standards Board ("FASB") has issued four new SFASs.
Three of these require new disclosures in financial statements for fiscal years
beginning after 15 December 1997, but none of which will impact the Group's net
income or shareholders' funds as reported under US GAAP.

SFAS 130, "Reporting Comprehensive Income", establishes standards for reporting
and display of comprehensive income and its components. It requires that all
items that are required to be recognized under US GAAP as components of
comprehensive income be reported in a financial statement that is displayed with
the same prominence as other financial statements. For the Group, such a
statement will present substantially the same information as that in the
consolidated statement of total recognized gains and losses presented under UK
GAAP except that the amounts reflected therein will be those measured under US
GAAP.

SFAS 131, "Disclosures about Segments of an Enterprise and Related Information",
which supersedes SFAS 14, "Financial Reporting for Segments of a Business
Enterprise", establishes standards for the way public business enterprises
report services, geographic areas and major customers in annual financial
statements. Other than in the initial year of application, SFAS 131 also
requires public business enterprises to report selected information about
operating segments in interim financial reports issued to shareholders. The
Group does not expect the adoption of this standard to have any impact on its
segmental disclosures under US GAAP.

SFAS 132, "Employers' Disclosures about Pensions and Other Post-retirement
Benefits" revises employers' disclosures about pension and other post-retirement
plans. Following the sale of Peabody on 19 May 1998, the Group has no
post-retirement obligations other than those relating to pensions. The principal
effect on the Group of SFAS 132 is that it replaces the existing requirement
under US GAAP for disclosure of the funded status of its defined benefit pension
plan with the requirement to disclose reconciliations of the beginning and
ending balances of the projected benefit obligation and the fair value of the
plan's assets and a statement of the funded status of the plan at the period
end.

33. Differences between UK GAAP and US GAAP (continued)

The fourth standard issued by FASB is SFAS 133, "Accounting for Derivative
Instruments and Hedging Activities" which is effective for fiscal years
beginning after 15 June 1999. This standard requires all derivatives to be
recognized as either assets or liabilities on the balance sheet at their fair
values. It also prescribes the accounting to be followed for the changes in the
fair values of derivatives depending upon their intended use and resulting
designation. It supersedes or amends the existing standards which deal with
hedge accounting and derivatives. The Company has not yet evaluated the effect
adopting this standard will have on the US GAAP amounts reported in its
financial statements.

New UK accounting standards applicable to the Group

In December 1997 the Accounting Standards Board in the United Kingdom (the ASB)
issued Financial Reporting Standard No. 9 "Associates and Joint Ventures" (FRS
9). FRS 9 sets out the definitions and accounting treatments for associated
undertakings, joint ventures and joint arrangements. It requires the Group's
share of results of associated undertakings to be analyzed between operating
income, interest, exceptional items and taxation. Previously the Group's share
of associated undertakings' income before tax was included in the consolidated
statements of income on a single line. FRS 9 requires the turnover and the
Group's share of assets and liabilities of joint ventures to be separately
disclosed, though the underlying accounting is the same as for associated
undertakings. FRS 9 is effective for accounting periods ending on or after 23
June 1998. The Group will comply with FRS 9 for its next accounting period and
prior year figures will be restated at that stage. Following the disposal of the
Peabody companies, the Group does not have any material interests in either
associated undertakings or joint ventures.

In December 1997 the ASB issued Financial Reporting Standard No. 10 "Goodwill
and Intangible Assets" (FRS 10). FRS 10 requires that purchased goodwill and
intangible assets should be capitalised as assets and amortised over the life of
the assets. Goodwill and intangible assets need not be amortised if it can be
demonstrated that the current market value of the goodwill or intangible asset
is not below its carrying value. FRS 10 is effective for accounting periods
ending on or after 23 December 1998. The Group will comply with FRS 10 for its
next accounting period. The standard does not require reinstatement of goodwill
previously set off against reserves and it is not anticipated the Group will
reinstate such goodwill.

In July 1998 the ASB issued Financial Reporting Standard No. 11 "Impairment of
Fixed Assets and Goodwill" (FRS 11). FRS 11 provides guidance on measurement of
the recoverable amount of assets, where any impairment loss should be recorded
and the related disclosures. FRS 11 is effective for accounting periods ending
on or after 23 December 1998. The Group will comply with the standard for its
next accounting period.

Accounting and disclosure of stock based compensation

FASB SFAS 123 - "Accounting for Stock-Based Compensation" which establishes
financial accounting and reporting standards for stock-based employee
compensation plans, is effective for accounting periods beginning after 15
December 1995. The Statement provides the option to continue under the
accounting provisions of Accounting Principles Board Opinion No. 25, "Accounting
for Stock Issued to Employees" (APB No. 25), providing that pro forma footnote
disclosures of the effects on net income and earnings per share, calculated as
if the new method had been implemented, are included. The Company has elected to
continue under APB No. 25, but the pro forma disclosures have been omitted, as
the effects on net income and earnings per share are not material.

Additional information required by US GAAP as at 31 March 1998 is shown below:

in the remaining contractual life which resulted from the acquisition of the
Company by the Texas Utilities group which took effect after the end of that
period (see Note 32).

34. Subsequent events

On 19 May 1998 the Group sold its investments in Peabody Holding Company, Inc.,
Gold Fields Mining Corporation, Citizens Power LLC and the holding companies of
the Group's Australian interests to P&L Coal Holdings Corporation, an affiliate
of Lehman Merchant Banking Partners II, LLP, for approximately $2.3 billion plus
the assumption of debt.

Immediately following completion of those sales, Texas Utilities declared its
offer for the shares of the Company wholly unconditional.

On 26 June 1998 Texas Utilities instigated and on 7 August 1998 it completed the
procedure to acquire compulsorily the remaining issued shares in the Company
which it did not already own, pursuant to section 429 of the Companies Act 1985.

On 12 August 1998 the Company was re-registered as a private company with the
name The Energy Group Limited.

Unaudited subsequent events disclosures

Following the sale of its former US and Australian coal and energy trading 
interests on May 19, 1998, the Company continued to be the guarantor of certain 
obligations of former subsidiaries whose results are now treated as 
discontinued operations.  Some of those guarantees have subsequently been 
released, but the Company continues to guarantee certain obligations relating 
to former subsidiaries of the Company (the Guarantees).

With effect from the close of business on October 22, 1998, an indirect
wholly-owned subsidiary of the Company sold its shareholdings in each of Eastern
Group plc, Energy Holdings (No. 2) Limited and Energy Group Holdings B.V. to
Suptrade Limited, another wholly-owned subsidiary of TU Acquisitions PLC, for a
total price of L.2,635 million.  As a consequence of this restructuring, the
Company and certain other affiliated UK subsidiaries of Texas Utilities may be
required to make certain adjustments to the Guarantees, which the Directors of
the Company do not currently expect to have a material adverse impact on the
Company.

The Company changed its name to Energy Holdings (No. 3) Limited and Suptrade 
Limited changed its name to The Energy Group Limited on October 27, 1998.
