                             % SENIOR NOTES DUE 2006
 
                                 ------------
   
  Southern Investments UK plc, a public limited company incorporated under the
laws of England and Wales (the "Company"), is offering (the "Offering")
US$235,000,000 aggregate principal amount of its  % Senior Notes due 2006 (the
"Senior Notes"). Interest on the Senior Notes will be payable semiannually on
      and          of each year, commencing       , 1996. The Senior Notes will
mature on      , 2006 at their principal amount unless previously redeemed.
       
  The Senior Notes will be redeemable prior to maturity only as described
below. The Senior Notes will be redeemable, in whole but not in part, at the
principal amount thereof, plus any accrued and unpaid interest, in the event of
certain tax law changes and other events requiring the payment of Additional
Amounts (as defined herein). The Senior Notes may also be redeemed in whole or
in part at the option of the Company at any time, at a redemption price equal
to the greater of (i) 100% of the principal amount of the Senior Notes being
redeemed or (ii) the sum of the present values of the remaining scheduled
payments of principal of and interest on the Senior Notes being redeemed
discounted to the date of redemption on a semi-annual basis (assuming a 360-day
year consisting of twelve 30-day months) at the Treasury Yield (as defined
herein) plus   basis points; plus, for (i) or (ii) above, whichever is
applicable, accrued interest on the Senior Notes to the date of redemption. The
Senior Notes will not be subject to any sinking fund. See "Description of the
Senior Notes."     
   
  The Senior Notes will be direct, unsecured and unsubordinated obligations of
the Company ranking pari passu with all other unsecured and unsubordinated
obligations of the Company (other than those obligations preferred by operation
of law). The Senior Notes will effectively rank junior to any secured
indebtedness of the Company to the extent of the assets securing such
indebtedness and to any indebtedness of the Company's subsidiaries to the
extent of the assets of such subsidiaries. Substantially all of the Company's
consolidated assets other than the stock of its only Significant Subsidiary (as
defined herein) are currently held by the Company's subsidiaries. At June 30,
1996, the Company had unsecured and unsubordinated debt obligations in the
amount of (Pounds)205.3 million (US$319.1 million) which will rank pari passu
with the Senior Notes. This amount does not include approximately (Pounds)147
million (US$228 million) of debt of the Company which will be refinanced with
the proceeds of this Offering. See "Use of Proceeds." At June 30, 1996, the
Company had no secured debt. Also at June 30, 1996, SWEB had indebtedness of
approximately (Pounds)285 million (US$443 million) outstanding to parties other
than the Company. The Indenture for the Senior Notes contains no restrictions
on the amount of additional indebtedness which may be incurred by the Company
or its subsidiaries; however, the Indenture contains certain restrictions on
the ability of the Company and its Significant Subsidiaries to incur secured
indebtedness. See "Description of the Senior Notes--Covenants--Limitation on
Liens."     
 
  The Senior Notes will be represented by a global Senior Note (the "Global
Note") in bearer form and deposited with Bankers Trust Company, as depositary
(the "Book-Entry Depositary"), which will hold the Senior Notes for the benefit
of The Depository Trust Company ("DTC") and its participants, including
Euroclear (as defined herein) and Cedel Bank (as defined herein). The Book-
Entry Depositary will issue to DTC one or more certificateless depositary
interests (the "Book-Entry Interest") which together will represent a 100%
interest in the underlying Global Note. DTC will operate a system of dealing in
the Book-Entry Interest in book-entry form. Interests in the Book-Entry
Interest will be shown on, and transfers thereof will be effected only through,
records maintained by DTC and its participants. Except in
limited circumstances, registered definitive Senior Notes will not be issued in
exchange for interests in the Global Note. Interests in the Book-Entry Interest
will clear and settle in DTC's Same-Day Funds Settlement System. Interests in
the Book-Entry Interest will be issued only in denominations of US$1,000 and
integral multiples thereof. See "Description of the Senior Notes--Description
of the Book-Entry System."

  The Company is a public limited company incorporated under the laws of
England and Wales. Several of the directors and executive officers of the
Company (and certain experts named in this Prospectus) are citizens or
residents of the United Kingdom (the "UK"). All or a substantial portion of
the assets of such persons and substantially all the assets of the Company are
located outside the United States of America (the "US"). As a result, it may
not be possible for investors to effect service of process within the US upon
such persons or the Company or to enforce against them judgments of US courts
predicated upon civil liabilities under US federal securities laws. There is
doubt as to the enforceability in England and Wales, in original actions or in
actions for enforcement of judgments of US courts, of civil liabilities
predicated upon US federal securities laws.
   
  The Indenture and the Senior Notes will be governed by, and construed in
accordance with, the laws of the State of New York. The Company has submitted
to the non-exclusive jurisdiction of the Supreme Court of New York, New York
County and the United States District Court for the Southern District of New
York and any appellate court from either thereof for any suit, legal action or
proceeding against the Company or its properties, assets or revenues with
respect to its obligations, liabilities or any other matter arising out of or
in connection with the Indenture or the Senior Notes. See "Description of the

                                    SUMMARY
 
  The following summary is qualified in its entirety by, and should be read in
conjunction with, the more detailed financial and other information contained
elsewhere in this Prospectus. References herein to the "Predecessor Company"
mean SWEB prior to its acquisition by the Company. All references to a "fiscal"
year mean a year ended March 31 and all references to a "calendar" year mean a
year ended December 31. References to Pro Forma Fiscal Year 1996 mean the
unaudited pro forma financial information of the Company presented for fiscal
year 1996 as if the acquisition of SWEB by the Company had occurred as of April
1, 1995.
 
                                  THE COMPANY
   
  The Company is a wholly-owned subsidiary of Southern Investments UK Holdings
Limited ("Holdings"), of which 75% is owned indirectly by The Southern Company
("Southern", together with its subsidiaries, the "Southern Company system") and
25% is owned indirectly by PP&L Resources, Inc. ("PP&L Resources"). The Company
was incorporated as a public limited company under the laws of England and
Wales on June 23, 1995, as a vehicle for the acquisition of South Western
Electricity plc ("SWEB"), one of the 12 regional electricity companies ("RECs")
in England and Wales licensed to distribute, supply and, to a limited extent,
generate electricity. In September 1995, the Company gained effective control
of SWEB, having acquired approximately 84% of its shares. The Company
subsequently replaced SWEB's board of directors and certain senior managers
with officers and employees of companies from within the Southern Company
system. In November 1995, the Company acquired the remaining shares of SWEB.
The Company's sole investment and only significant asset is the entire share
capital of SWEB, which is headquartered in Bristol, England. At June 30, 1996,
the Company had consolidated assets of (Pounds)1.659 billion ($2.576 billion).
See "The Company."     
 
  SWEB's two main business lines are the distribution of electricity and the
supply of electricity to approximately 1.3 million customers primarily in its
franchise area in southwest England (the "Franchise Area"). This area covers
approximately 5,560 square miles and has a resident population of approximately
2.8 million. The distribution business and the supply business are distinct
business segments and produced operating income of (Pounds)112 million ($174
million) and (Pounds)15 million ($23 million), respectively, in Pro Forma
Fiscal Year 1996, representing substantially all of the Company's consolidated
operating income in that pro forma fiscal year. See "Business--SWEB's Main
Businesses."
 
  SWEB is the only distributor of electricity in its Franchise Area, and
management believes that economic, environmental and regulatory factors are
likely to prevent competitors from entering this business in SWEB's Franchise
Area. SWEB has an exclusive right to supply electricity to customers in its
Franchise Area with demand of not more than 100kW, which is scheduled to
continue until at least March 31, 1998. The supply business to consumers with
demand above 100kW, both inside and outside SWEB's Franchise Area, is open to
competition, and SWEB is able to competitively bid or negotiate to supply
electricity to such customers. See "The Electric Utility Industry in Great
Britain."
 
  The operations of SWEB are regulated under its Public Electricity Supply
license ("PES license") pursuant to which the distribution business, and the
supply business to consumers with demand of not more than 100kW, are subject to
a price cap regulatory framework that provides economic incentives to SWEB to
increase the number of units of electricity distributed and supplied and to
operate in a more cost-efficient manner.
 
  SWEB also has ancillary business activities that support the main businesses,
including power generation and gas supply. See "Business--SWEB's Other Business
Activities."

Interest......................      The Senior Notes will bear interest from
                                    the date of original issuance at the rate
                                    of  % per annum payable semiannually in
                                    arrears.
 
Interest Payment Dates........           and     , commencing     , 1996.

                                    The Senior Notes are direct, unsecured and
                                    unsubordinated obligations of the Company
                                    ranking pari passu with all other unsecured
                                    and unsubordinated obligations of the
                                    Company (other than those obligations
                                    preferred by operation of law). The Senior
                                    Notes will effectively rank junior to any
                                    secured indebtedness of the Company to the
                                    extent of the assets securing such
                                    indebtedness and to any indebtedness of the
                                    Company's subsidiaries to the extent of the
                                    assets of such subsidiaries. Substantially
                                    all of the Company's consolidated assets
                                    other than the stock of SWEB, the Company's
                                    only Significant Subsidiary (as defined
                                    herein), are currently held by the
                                    Company's subsidiaries. At June 30, 1996,
                                    the Company had unsecured and
                                    unsubordinated debt obligations in the
                                    amount of (Pounds)205.3 million ($319.1
                                    million) which will rank pari passu with
                                    the Senior Notes. This amount does not
                                    include approximately (Pounds)147 million
                                    ($228 million) of debt of the Company which
                                    will be refinanced with the proceeds of
                                    this Offering. See "Use of Proceeds." At
                                    June 30, 1996, the Company had no secured
                                    debt. Also at June 30, 1996, SWEB had
                                    indebtedness of approximately (Pounds)285
                                    million ($443 million) outstanding to
                                    parties other than the Company. The
                                    Indenture for the Senior Notes contains no
                                    restrictions on the amount of additional
                                    indebtedness which may be incurred by the
                                    Company or its subsidiaries; however, the
                                    Indenture contains certain restrictions on
                                    the ability of the Company and its
                                    Significant Subsidiaries to incur secured
                                    indebtedness. See "Description of the
                                    Senior Notes--Covenants."     
 
Ratings.......................      The Senior Notes have been assigned ratings
                                    of     by Standard & Poor's Ratings
                                    Services ("S&P"),     by Duff & Phelps
                                    Credit Rating Company ("DCR") and     by
                                    Moody's Investors Service, Inc.
                                    ("Moody's"). These ratings have been
                                    obtained with the understanding that S&P,
                                    DCR and Moody's will continue to monitor
                                    the credit rating of the Company and will
                                    make future adjustments to the extent
                                    warranted. A rating reflects only

                                    the views of S&P, DCR or Moody's, as the
                                    case may be, and is not a recommendation to
                                    buy, sell or hold the Senior Notes. There
                                    is no assurance that any such rating will
                                    be retained for any given period of time or
                                    that it will not be revised downward or
                                    withdrawn entirely by S&P, DCR or Moody's,
                                    as the case may be, if, in their respective
                                    judgments, circumstances so warrant.
 
Optional Redemption...........      The Senior Notes will be redeemable in
                                    whole or in part at the option of the
                                    Company at any time, at a redemption price
                                    equal to the greater of (i) 100% of the
                                    principal amount of the Senior Notes being
                                    redeemed or (ii) the sum of the present
                                    values of the remaining scheduled payments
                                    of the principal of and interest on the
                                    Senior Notes being redeemed discounted to
                                    the date of redemption on a semi-annual
                                    basis (assuming a 360-day year consisting
                                    of twelve 30-day months) at the Treasury
                                    Yield (as defined herein) plus   basis
                                    points; plus, for (i) or (ii) above,
                                    whichever is applicable, accrued interest

                                    date of redemption. See "Description of the
                                    Senior Notes--Optional Redemption."
 
Optional Tax Redemption.......      In the event of changes in the tax laws of
                                    the UK after the date hereof and certain
                                    other events that would obligate the
                                    Company to pay Additional Amounts, the
                                    Senior Notes may be redeemed at the option
                                    of the Company, in whole but not in part,
                                    at the principal amount thereof, plus
                                    accrued and unpaid interest. See
                                    "Description of the Senior Notes--Optional
                                    Tax Redemption."
 
Principal Covenants...........      The Indenture under which the Senior Notes
                                    are to be issued will not contain any
                                    limitation on the Company's or its
                                    subsidiaries' right to incur indebtedness.
                                    The Indenture will, however, contain
                                    certain covenants, including covenants
                                    applicable to the Company and its

                                    will permit acceleration of the principal
                                    of the Senior Notes (together with all

                                    be made free and clear of any present or
                                    future UK withholding and other deductions
                                    existing in the UK, except as set forth
                                    under "Description of the Senior Notes--

                                    the Company will pay such additional
                                    amounts (the "Additional Amounts") as will
                                    result in receipt by the holder of the
                                    Global Note of such amounts as would have
                                    been received by it had no such withholding
                                    or deduction been required. See
                                    "Description of the Senior Notes--

 (1) The financial data for the Predecessor Company shown on pages (i) 8 and 11
     and (ii) 9 and 12 were derived from financial statements for the
     Predecessor Company prepared, respectively, in accordance with UK GAAP and
     US GAAP. The principal differences between US GAAP and UK GAAP as applied
     to the Predecessor Company relate to the treatment of discontinued
     operations, pension costs and deferred taxes.
 (2) A provision for the disposition of the electrical appliance retailing
     business resulted in an exceptional item for the fiscal year ended March
     31, 1995. The actual disposition of this business segment occurred in June
     1995.
 (3) Excluding the exceptional item, profit for fiscal year 1995 would have
     been (Pounds)98 million.
   
 (4) EBIT equals income from continuing operations before the sum of interest
     expense and income taxes. This information is provided for informational
     purposes only and such measure should not be construed as an alternative
     to operating income (as determined in accordance with GAAP) as an
     indicator of operating performance, or as an alternative to cash flows
     from operating activities (as determined in accordance with GAAP) as a
     measure of liquidity.     
   
 (5) EBITDA equals income from continuing operations before the sum of interest
     expense, income taxes, depreciation and amortization. This information is
     provided for informational purposes only and such measure should not be
     construed as an alternative to operating income (as determined in
     accordance with GAAP) as an indicator of operating performance, or as an
     alternative to cash flows from operating activities (as determined in
     accordance with GAAP) as a measure of liquidity.     
 (6) Cash flow from operations increased in fiscal year 1994 as a result of
     customers who paid bills in advance in order to avoid paying value added
     taxes which were introduced by the British government.
 (7) The ratio of earnings to fixed charges is computed as the sum of pretax
     income from continuing operations and fixed charges divided by fixed
     charges. Fixed charges consist of interest expensed.
 (8) On September 18, 1995, the Successor Company obtained effective control of
     the Predecessor Company pursuant to the Successor Company's offer to
     acquire the Predecessor Company.
   
 (9) Pro Forma Fiscal Year 1996 financial information gives effect to the
     acquisition of the Predecessor Company by the Successor Company as if it
     had occurred on April 1, 1995. See pages F-39 and F-40 included in this
     Prospectus.     
(10) Solely for the convenience of the reader, pounds sterling amounts have
     been translated into US dollars at the Noon Buying Rate on June 28, 1996
     of $1.5529 = (Pounds)1.00.
(11) Intra-business eliminations consist primarily of intercompany transactions
     between the distribution business and the supply business and intra-
     business transactions between ancillary support businesses. Pursuant to
     the UK regulatory framework, SWEB's distribution of electricity to its
     supply customers within its own Franchise Area is billed to SWEB's supply
     business, which in turn incorporates the distribution charge into the bill
     sent to the final end user.
   
(12) Includes goodwill, net of amortization, and prepaid pension costs of
     (Pounds)173 million ($269 million) and (Pounds)95 million ($148 million),
     respectively at March 31, 1996.     
   
(13) Cash flow from operations for the period from inception (June 23, 1995) to
     March 31, 1996 includes the settlement of accounts payable balances of
     (Pounds)39 million ($60 million).

                                 RISK FACTORS
 
  In addition to the other information in this Prospectus, the following
factors should be considered carefully in evaluating an investment in the
Senior Notes offered by this Prospectus.
 
FACTORS RELATING TO THE ELECTRIC UTILITY BUSINESS IN GREAT BRITAIN
 
PRICE REGULATION OF DISTRIBUTION
   
  The distribution business of SWEB is regulated under its PES license
pursuant to which revenue of the distribution business is controlled by the
Distribution Price Control Formula (as defined herein). The Distribution Price
Control Formula determines the maximum average price per unit of electricity
(expressed in kilowatt hours, a "unit") that a REC may charge. The elements
used in the Distribution Price Control Formula are established for a five-year
period and are subject to review by the Director General of Electricity Supply
(the "Regulator") at the end of each five-year period and at other times in
the discretion of the Regulator. At each review, the Regulator can adjust the
value of certain elements in the Distribution Price Control Formula. In July
1994, a review resulted in a 14% price reduction, before allowing for
inflation, effective April 1, 1995. In July 1995, a further review of
distribution prices was concluded by the Regulator for fiscal years 1997 to
2000. As a result of this further review, SWEB's distribution prices were
reduced by a further 11%, before allowing for inflation, effective April 1,
1996. There can be no assurance that any review by the Regulator will not
adversely affect the Company. See "The Electric Utility Industry in Great
Britain--The Structure of the Electricity Industry in Great Britain--
Distribution of Electricity."     
 
COMPETITION IN SUPPLY
 
  Each PES license holder currently has an exclusive right, subject to price
cap regulation, to supply customers in its franchise area with a maximum
demand of not more than 100kW ("Franchise Supply Customers"). However, the
supply business is being progressively opened to competition. The market for
customers with a maximum demand above 1MW has been open to competition for
suppliers of electricity since privatization while, for customers with a
maximum demand above 100kW ("Non-Franchise Supply Customers"), the market
became competitive in April 1994. The final stage of this process is expected
to occur on March 31, 1998, when the exclusive right to supply Franchise
Supply Customers is scheduled to end. There can be no assurance that
competition among suppliers of electricity will not adversely affect the
Company. See"Business--SWEB's Main Businesses--Supply Business."
 
POOL PURCHASE PRICE VOLATILITY
 
  SWEB's supply business to Non-Franchise Supply Customers generally involves
entering into fixed price contracts to supply electricity to its customers.
SWEB obtains the electricity to satisfy its obligations under such contracts
primarily by purchases from the wholesale trading market for electricity in
England and Wales (the "Pool"). See "The Electric Utility Industry in Great
Britain." Because the price of electricity purchased from the Pool can be
volatile, to the extent that SWEB purchases electricity from the Pool, SWEB is
exposed to risk arising from differences between the fixed price at which it
sells and the fluctuating prices at which it purchases electricity unless it
can effectively hedge such exposure. SWEB's ability to manage such risk at
acceptable levels will depend, in part, on the specifics of the supply
contracts that SWEB enters into, SWEB's ability to implement and manage an
appropriate hedging strategy and the development of an adequate market for
hedging instruments. No assurance can be given that this risk will be
effectively mitigated. See "Business--SWEB's Main Business--Supply Business."

CHANGE IN GOVERNMENT POLICY
 
  The Conservative Party has held power in the UK since 1979 and currently has
a one-seat majority over all other parties. The next general election in the
UK must be held no later than May 1997, and may be called at approximately
three weeks' notice at any time before then. Certain senior members of the
Labour Party, which is the main opposition party, have recently made
statements regarding policies which a Labour government would intend to
introduce, including a windfall tax on excess profits of privatized utilities
and referring the whole electricity industry to the competition authorities.
There can be no assurance that the policies of the UK government, by whichever
party it is controlled, would not adversely affect the Company.

CURRENCY RISKS; HEDGING TRANSACTIONS
 
  The Company expects to obtain a significant portion of its financing from
the sale of the Senior Notes which will be denominated in US dollars. The
Company's revenues will be generated primarily in pounds sterling while the
Company's interest and principal payment obligations with respect to the
Senior Notes will be payable in US dollars. As a result, any change in the
currency exchange rate that reduces the amount in pounds sterling obtained
upon conversion of the US dollar-based net proceeds of the Senior Notes or
that increases the effective principal and interest payment obligations
represented by the Senior Notes upon conversion of pounds sterling-based
revenues into US dollars may, if not appropriately hedged, have a material
adverse effect on the Company or on its ability to make payments on the Senior
Notes. See "Exchange Rates" for certain information concerning the Noon Buying
Rate for pounds sterling expressed in US dollars. Although the Company expects
to enter into certain transactions to hedge risks associated with exchange
rate fluctuations, there can be no assurance that the Company will engage in
such transactions or that any such transaction will be successful in reducing
such risks.
 
LACK OF ESTABLISHED MARKET FOR THE SENIOR NOTES
 
  Although the Underwriters have informed the Company that they currently
intend to make a market in the Senior Notes, they are not obligated to do so,
and any such market-making may be discontinued at any time without notice.
There can be no assurance as to the development or liquidity of any market for
the Senior Notes. If an active public market does not develop, the market
price and liquidity of the Senior Notes may be adversely affected.
 
CONSIDERATIONS RELATED TO BOOK-ENTRY INTEREST
 
  Unless and until Definitive Registered Notes are issued in exchange for
interests in the Book-Entry Interest, owners of interests in the Book-Entry
Interest will not be considered the owners or holders of Senior Notes under
the Indenture. The Book-Entry Depositary, or its nominee, will be the sole
holder (the "Holder") of the Senior Notes in the form of a single global
Senior Note in bearer form. Accordingly, each person owning an interest in the
Book-Entry Interest must rely on the procedures of the Book-Entry Depositary
and DTC and, if such person is not a Participant in DTC, on the procedures of
the Participant (including Euroclear and Cedel Bank) through which such person
owns its interest to exercise any rights and obligations of a Holder under the
Indenture.
 
  Payments of principal, interest and other amounts owing on or in respect of
the Global Note will be made to the Book-Entry Depositary, which will in turn
distribute payments to Cede & Co. (as nominee of DTC), and thereafter payments
will be made to DTC Participants (and to persons who own an interest in the
Book-Entry Interest through DTC Participants). None of the Company, the
Trustee, the Book-Entry Depositary, any paying agent or any registrar will
have any responsibility or liability for any aspect of the records relating
to, or payments made on account of, the Book-Entry Interest or interests
therein or for maintaining, supervising or reviewing any records relating to
such Book-Entry Interest or interests therein.
 
  Unlike Holders of the Senior Notes themselves, owners of interests in the
Book-Entry Interest will not have the direct right under the Indenture to act
upon solicitations by the Company of consents or requests by the Company for
waivers or other actions from Holders of the Senior Notes. Instead, owners of
interests in the Book-Entry Interest will be permitted to act only to the
extent they have received appropriate proxies to do so from DTC and, if
applicable, DTC Participants. There can be no assurance that procedures
implemented for the granting of such proxies will be sufficient to enable
owners of interests in the Book-Entry Interest to vote on any requested
actions on a timely basis. Similarly, upon the occurrence of an Event of
Default (as defined), unless and until Definitive Registered Notes are issued,
owners of interests in the Book-Entry Interest will be restricted to acting
through DTC, its Participants and the Book-Entry Depositary. There can be no
assurance that the procedures to be implemented by DTC, its Participants and
the Book-Entry Depositary under such circumstances will be adequate to ensure
the timely exercise of remedies under the Indenture. See "Description of the
Senior Notes--Description of the Book-Entry System."

                                  THE COMPANY
   
  The Company is a wholly-owned subsidiary of Holdings, of which 75% is owned
indirectly by Southern and 25% is owned indirectly by PP&L Resources. The
Company was incorporated as a public limited company under the laws of England
and Wales on June 23, 1995, as a vehicle for the acquisition of SWEB, one of
the 12 RECs in England and Wales licensed to distribute, supply and, to a
limited extent, generate electricity. In September 1995, the Company gained
effective control of SWEB, having acquired approximately 84% of its shares.
The Company subsequently replaced SWEB's board of directors and certain senior
managers with officers and employees of companies from within the Southern
Company system. In November 1995, the Company acquired the remaining shares of
SWEB. The Company's sole investment and only significant asset is the entire
share capital of SWEB, which is headquartered in Bristol, England. At June 30,
1996, the Company had consolidated assets of (Pounds)1.659 billion ($2.576
billion). The following organizational chart illustrates the ownership
structure of the Company and SWEB in summary form.     
 
                                     LOGO
 
  SWEB's two main business lines are the distribution of electricity and the
supply of electricity to approximately 1.3 million customers in its Franchise
Area. The distribution business and the supply business are distinct business
segments and produced operating income of (Pounds)112 million ($174 million)
and (Pounds)15 million ($23 million), respectively, in Pro Forma Fiscal Year
1996, representing substantially all of the Company's consolidated operating
income in that pro forma fiscal year.
 
  The Company's registered office and principal executive offices are located
at 800 Park Avenue, Aztec West, Almondsbury, Bristol BS12 4SE, England, and
its telephone number is 44-1454-201-101.
 
FRANCHISE AREA
 
  SWEB operates primarily in its Franchise Area which covers approximately
5,560 square miles extending from Bristol and Bath in the northeast, 188 miles
southwest along the peninsula to Land's End and 28 miles beyond to the Isles
of Scilly. SWEB's Franchise Area has a resident population of approximately
2.8 million. The map on the inside front cover of this Prospectus outlines
SWEB's Franchise Area.

REGULATION
 
  The revenues and operations of SWEB are regulated by the Regulator through
SWEB's PES license. Under that license, SWEB provides electricity distribution
services to virtually all consumers in its Franchise Area (whether supplied by
SWEB's independent supply business or by other suppliers) and must offer
electricity supply services to all consumers in its Franchise Area. Franchise
Supply Customers within the Franchise Area (primarily residential/domestic and
small commercial consumers) can only be supplied by SWEB. Non-Franchise Supply
Customers within the Franchise Area (primarily large commercial and
agricultural and industrial consumers) may choose to be supplied by SWEB or
another supplier. Similarly, SWEB may supply electricity to Non-Franchise
Supply Customers outside SWEB's Franchise Area.
 
  Under the terms of SWEB's PES license, the distribution business and the
supply business to Franchise Supply Customers are subject to a price cap
regulatory framework that provides economic incentives to SWEB to increase the
number of units of electricity distributed and supplied and to operate in a
cost-efficient manner. The price cap framework, however, does not apply to
Non-Franchise Supply Customers, and SWEB is able to competitively bid or
negotiate to supply electricity to such customers. SWEB's PES license also
limits the scope of SWEB's business activities and its ability, among other
things, to transfer assets and make loans. See "The Electric Utility Industry
in Great Britain--The Structure of the Electricity Industry in Great Britain--
Distribution of Electricity" and "--Electricity Supply."
 
DISTRIBUTION BUSINESS
 
  SWEB's distribution business is the ownership, management and operation of
the electricity distribution network within SWEB's Franchise Area. The primary
activity of the distribution business is the receipt of electricity from the
national grid transmission system and its distribution to end users of
electricity that are connected to SWEB's power lines. Virtually all
electricity supplied (whether by SWEB's independent supply business or by
other suppliers) to consumers in SWEB's Franchise Area is transported through
its distribution network, thus providing SWEB with distribution volume that is
stable from year to year.
 
  SWEB's distribution business has grown in both its customer base and in the
number of units distributed, primarily reflecting economic growth in the South
West of England. The South West, of which the Franchise Area forms the greater
part, has benefited from economic growth (as measured by gross domestic
product, "GDP") which exceeded the UK average from 1991 through 1995 and has
also benefited from an average unemployment rate during calendar year 1995 of
approximately 6.9%, which was below the UK average of 8.2%, according to a
recent study by Cambridge Econometrics. At March 31, 1996, SWEB had
experienced a 5-year compound annual growth rate of 0.8% in customers and a 5-
year compound annual growth rate of 1.6% in units distributed.
 
  Since its acquisition by the Company, SWEB has introduced several
initiatives that focus on its distribution business. A number of areas for
cost savings and performance improvement have been identified which, together
with service innovations, are expected to improve the current level of
customer satisfaction and SWEB's financial performance. In this regard, a
total of 704 staff reductions (mainly in the distribution business and
representing 21% of staff at the time of the acquisition by the Company of
SWEB) are planned, of which 460 occurred prior to June 30, 1996. In addition,
new work practices developed in consultation with SWEB's unions have
contributed to cost savings. See "Business--SWEB's Main Businesses--
Distribution Business--Strategy."
 
SUPPLY BUSINESS
 
  SWEB's supply business is selling electricity to end users, purchasing such
electricity, primarily from the Pool, and arranging for its distribution to
those end users. SWEB's supply business is comprised predominantly of
supplying Franchise Supply Customers. In fiscal year 1996, these customers
accounted for approximately 82% of all units of electricity supplied by SWEB.
SWEB's exclusive right to supply these customers is scheduled to
 
                                      17
<PAGE>
 
continue, subject to price regulation, until March 31, 1998, at which time
competition to supply Franchise Supply Customers is scheduled to commence.
 
  Since its acquisition by the Company, SWEB has completed a review of the
supply market, established new goals for its supply business and adopted new
strategies for achieving those goals. The key goals established are the
retention of its current Franchise Supply Customers as supply customers after
March 31, 1998 and the increase of SWEB's share of electricity supplied to
Non-Franchise Supply Customers both inside and outside SWEB's Franchise Area.
As a result of this strategy, SWEB expects to supply a larger portion of units
to Non-Franchise Supply Customers than in fiscal year 1996.
 
  SWEB's strategy for retaining its Franchise Supply Customers is to build
customer loyalty and offer competitive prices. SWEB seeks to build customer
loyalty by providing superior service, including reliable distribution
service. To provide responsive service for billing and other matters, SWEB has
installed a state-of-the-art call center to handle customers' needs and is
completing work on a new billing system to provide customers with important
information in a user-friendly format.
 
  Most of SWEB's Non-Franchise Supply Customers, who are primarily large
commercial and industrial companies, are located in SWEB's Franchise Area.
They are typically supplied through individual contracts for a duration of one
to two years based on competitively bid or negotiated prices.
 
  SWEB's strategy for increasing market share among Non-Franchise Supply
Customers is to provide more competitive pricing, the superior service
described above and customized service that will be supported through an
expanded staff of key customer account managers utilizing new integrated
information systems.
 
OTHER BUSINESS ACTIVITIES
 
  SWEB also has ancillary business activities that support the main
electricity businesses, including power generation and gas supply. See
"Business--SWEB's Other Business Activities."
 
PARENT COMPANIES
 
  Southern owns several companies that together constitute one of the largest
investor-owned electric utility systems in the United States in terms of total
sales, electricity revenues and installed capacity. The Southern Company
system provides energy to approximately 4.8 million customers in Alabama,
Georgia, the panhandle of Florida, southeastern Mississippi and southwestern
England through its five southeastern United States utility operating
subsidiaries, which are Alabama Power Company, Georgia Power Company, Gulf
Power Company, Mississippi Power Company and Savannah Electric and Power
Company, and in England through SWEB. The Southern Company system currently
has ownership interests in over 70 power plants with more than 300 generating
units and with total electric generating capacity of over 32,000 MW. Southern
Electric International, Inc. ("Southern Electric"), a wholly owned subsidiary
of Southern, focuses on management of, and investment opportunities related
to, international and domestic power generation, the independent US domestic
power market and international electricity businesses. Within the Southern
Company system, Southern Electric has management oversight responsibility for
Holdings, the Company and SWEB, as well as certain other investments by the
Southern Company system in electricity businesses in the United States,
Argentina, Chile, the Bahamas and Trinidad and Tobago. SWEB is the third
largest operating company in the Southern Company system in terms of revenue,
assets and number of customers. The acquisition of SWEB is consistent with
Southern's stated objective of growing businesses outside of its core US
regulated utilities to contribute to the consolidated earnings growth of
Southern.
 
  In late 1994, PP&L Resources established the Power Markets Development
Company ("PMDC") as its non-regulated, international power business. In
addition to its indirect minority ownership interest in SWEB, PMDC owns
interests in operating companies in Portugal, Bolivia and Argentina and is
currently developing power projects in Peru, Spain and India. The investment
by PP&L Resources in Holdings is significantly greater than that in any of
these other companies.

                                USE OF PROCEEDS
 
  The net proceeds from the Offering are estimated to be approximately US$228
million ((Pounds)147 million) after deduction of underwriting commissions and
discounts and expenses payable by the Company.
   
  The Company intends to use such net proceeds to refinance a portion of an
existing $505 million ((Pounds)325 million) term loan. The existing term loan
matures on February 5, 1997 and bears interest at the London inter-bank
offered rate for pounds sterling plus 20 basis points. Morgan Guaranty Trust
Company of New York ("Morgan Guaranty"), an affiliate of J.P. Morgan
Securities Inc., one of the Underwriters ("JP Morgan") is a lender and agent
under the Company's term loan, and as such lender will receive a portion of
the proceeds of the Offering in excess of 10% of such proceeds in repayment of
a portion of such term loan. See "Underwriting."

                            SELECTED FINANCIAL DATA
 
  The income statement and balance sheet data of the Predecessor Company for
each of the four fiscal years ended 1995 and for the period from April 1 to
September 17, 1995, and of the Company (the "Successor Company" or the
"Company") for the period from September 18, 1995 to March 31, 1996 have been
derived from the audited consoldiated financial statements of the Predecessor
Company and the Successor Company, respectively. The unaudited consolidated
income statement data for the three months ended June 30, 1995 and 1996, have
been derived from the unaudited consolidated financial statements of the
Predecessor and Successor Company, respectively. The unaudited consolidated
balance sheet data as of June 30, 1996 have been derived from the financial
statements of the Successor Company. In the opinion of the management of the
Company, all adjustments (consisting of only normal recurring adjustments)
considered necessary for fair presentation of the condensed unaudited
consolidated financial statements have been included, and the accompanying
condensed consolidated financial statements present fairly the financial
position and the results of operations for the interim periods presented. See

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
  The following discussion should be read in conjunction with the consolidated
financial statements and the notes thereto of Southern Investments UK plc (the
"Successor Company" or the "Company") and of South Western Electricity plc
(the "Predecessor Company" or "SWEB") and "Selected Financial Data" included
elsewhere in this Prospectus. The consolidated financial statements of the
Successor Company and the consolidated financial statements of the Predecessor
Company discussed in this Section are presented in accordance with US GAAP.
 
INTRODUCTION
 
BACKGROUND
   
  The Company was incorporated as a public limited company under the laws of
England and Wales in June 1995, as a vehicle for the acquisition of SWEB. In
September 1995, the Company gained effective control of SWEB, having acquired
approximately 84% of its shares. The Company subsequently replaced SWEB's
board of directors and certain senior managers with officers and employees of
companies from within the Southern Company system. In November 1995, the
Company acquired the remaining shares of SWEB. Total consideration for the
acquisition was (Pounds)1.063 billion ($1.651 billion) excluding a special
dividend of (Pounds)52 million ($81 million) paid by SWEB to its former
shareholders (other than those whose shares the Company had purchased in the
open market). Such dividend, when considered in aggregate with the final
dividend of (Pounds)23 million ($35 million) paid in October 1995 in respect
of fiscal year 1995, yields the (Pounds)75 million ($116 million) payment of
preacquisition dividends disclosed in the financial statements located
elsewhere in this prospectus.     
 
ACCOUNTING FOR THE ACQUISITION
 
  The recorded assets and liabilities of SWEB immediately prior to the time
the Company gained effective control of SWEB were (Pounds)855 million and
(Pounds)515 million, respectively. As a result of the purchase method of
accounting, the amount of SWEB's assets recorded on the books of the Company
was increased by (Pounds)910 million to their fair value of (Pounds)1.765
billion ($2.741 billion), and the amount of SWEB's liabilities recorded on the
books of the Company was increased by (Pounds)362 million to their fair value
of (Pounds)877 million ($1.362 billion). The increase in liabilities included
the establishment of reserves totaling (Pounds)44 million related principally
to staff reductions and the disposition of ancillary businesses. The resulting
difference between the purchase price of (Pounds)1.063 billion and the
difference between the fair value of the assets acquired and the fair value of
the liabilities assumed as well as the reserves established resulted in
goodwill of (Pounds)175 million.
 
  The unaudited pro forma information presented for fiscal year 1996 ("Pro
Forma Fiscal Year 1996") consists of the historical results of operations of
the Predecessor Company prior to the acquisition and the results of operations
of the Successor Company subsequent to the acquisition, both of which have
been adjusted for the effects of the acquisition as though it had taken place
on April 1, 1995. The effects of the acquisition that are reflected in Pro
Forma Fiscal Year 1996 include: (i) depreciation expense based on property,
plant and equipment valued according to the purchase method of accounting as
if the acquisition had occurred on April 1, 1995, (ii) amortization of
goodwill valued according to the purchase method of accounting as if the
acquisition had occurred on April 1, 1995, (iii) fair valuation of existing
liabilities and the related interest expense as if the acquisition had
occurred on April 1, 1995, (iv) debt issued to finance the acquisition and the
related interest expense as if the acquisition had occurred on April 1, 1995
and (v) recognition of pension fund surplus and the reduction of pension
expense in the accounts of the Company. The information for Pro Forma Fiscal
Year 1996 is presented for illustrative purposes only and does not purport to
represent the actual results that would have occurred if the acquisition had
taken place on April 1, 1995.
 
SIGNIFICANT EVENTS
 
  During fiscal year 1996, the sale by SWEB of its shares in The National Grid
Group plc ("NGG") and related actions produced a nonrecurring pre-tax gain of
(Pounds)14 million over the fair value established at the time of the
Company's acquisition of effective control of SWEB and resulted in net pre-tax
cash flow of (Pounds)241 million. In October 1995, the 12 RECs and Her
Majesty's Government (owning one special share) agreed to seek a listing
 
                                      26
<PAGE>
 
   
for the NGG shares on the London Stock Exchange. The listing took place in
December 1995. Following that, SWEB progressively sold its approximately 6.3%
ownership interest in NGG for total proceeds of (Pounds)213 million, including
(Pounds)12 million in respect of shares sold by SWEB to the Company. The
listing was conditional upon the prior demerger of NGG's pumped storage
electricity generation business ("PSB") in order for NGG to sell that
business. PSB was sold in December 1995. SWEB had received (Pounds)36 million
of its share of the total proceeds from that sale by the end of fiscal year
1996. SWEB's estimated total share of the proceeds from the sale is (Pounds)39
million. As part of the agreement among the shareholders of NGG, each of the
RECs agreed to provide a discount to each of their respective Franchise Supply
Customers which, together with the associated reduction in the Fossil Fuel
Levy (as defined in "The Electric Utility Industry in Great Britain"),
produced a credit on each Franchise Supply Customer's bill of just over
(Pounds)50. The cost to SWEB of providing the discount amounted to (Pounds)57
million which was credited to customers in the last quarter of fiscal year
1996. In order to compensate the RECs for the cost of the customer discount
and other costs associated with the listing and sale, NGG paid a special
dividend shortly before the listing. SWEB's share of the special dividend
after taxation amounted to (Pounds)61 million. Between September 18, 1995 and
March 31, 1996, SWEB paid to the Company and the Company paid to Holdings a
dividend of (Pounds)191 million which was made possible because of the
proceeds from the sale of SWEB's interest in NGG.     
 
  SWEB has progressively withdrawn from its involvement in non-core
businesses. Neither the contribution to SWEB's or the Company's operating
income from the disposed businesses nor the effect of the dispositions on
SWEB's or the Company's net income was material after taking into account the
reserves established in connection with the acquisition. SWEB sold its
appliance retailing business in June 1995; its appliance servicing business in
February 1996; its creditor and warranty insurance business and electrical
installation and contracting business in March 1996; and its interest in a
cable television and telecommunications company in July 1996.
 
RESULTS OF OPERATIONS
 
THREE MONTHS ENDED JUNE 30, 1995 COMPARED WITH THREE MONTHS ENDED JUNE 30,
1996
 
  The condensed financial information included herein compares the results of
the Successor Company for the three months ended June 30, 1996 with those of
the Predecessor Company for the three months ended June 30, 1995.
 
 Earnings
 
  Operating income increased by (Pounds)1 million (4%) from (Pounds)26 million
in the three months ended June 30, 1995 to (Pounds)27 million in the three
months ended June 30, 1996. This increase was primarily due to an (Pounds)8
million increase in operating income from the supply business which was
partially offset by a (Pounds)4 million decrease in operating income from the
distribution business, resulting primarily from the price reduction mandated
by the Regulator, and a (Pounds)3 million decrease in operating income from
ancilliary businesses.
   
  Net income decreased by (Pounds)5 million (31%) from (Pounds)16 million in
the three months ended June 30, 1995 to (Pounds)11 million in the three months
ended June 30, 1996. This decrease was primarily attributable to increased
after-tax interest expense of (Pounds)7 million resulting from debt issued to
finance the acquisition, partially offset by an after-tax increase in other
income of (Pounds)1 million.     
 
 Revenues
 
  Operating revenues increased by (Pounds)14 million (8%) from (Pounds)167
million in the three months ended June 30, 1995 to (Pounds)181 million in the

  Two factors determine the amount of revenues produced by the main
electricity distribution business: the unit price of the electricity
distributed (which is controlled by the Distribution Price Control Formula)
and the number of electricity units distributed. Following the Regulator's
distribution price review in 1994, the Regulator reduced SWEB's allowable
expected distribution revenues, effective beginning fiscal year 1996, by 14%,
before an allowed increase for inflation. Subsequently, the Regulator
announced a further distribution price reduction which has had and will
continue to have the effect of reducing SWEB's allowable expected distribution
revenues, effective beginning fiscal year 1997, by a further 11%, before an
allowed increase for inflation. See "The Electric Utility Industry in Great
Britain." In the three months ended June 30, 1996, application of the
Distribution Price Control Formula resulted in a reduction in SWEB's
distribution revenues as compared to the three months ended June 30, 1995. The
number of units distributed depends on the demands of SWEB's customers for
electricity. That demand varies based, in part, upon weather conditions and
economic activity. Revenues from the distribution business decreased by
(Pounds)5 million (8%) from (Pounds)58 million for the three months ended June
30, 1995 to (Pounds)53 million for the three months ended June 30, 1996 as a
result of the following factors:

</TABLE>
 
  Two factors determine the amount of revenues produced by the supply
business: the unit price of the electricity supplied (which, in the case of
Franchise Supply Customers, is controlled by the Supply Price Control Formula)
and the number of electricity units supplied. Until April 1998, SWEB is
expected to have the exclusive right to supply all Franchise Supply Customers
in its Franchise Area.
 
  Franchise Supply Customers are generally residential/domestic and small
commercial customers. The volume of unit sales of electricity for Franchise
Supply Customers is influenced largely by the number of customers in the
Franchise Area, weather conditions and prevailing economic conditions. Unit
sales to Non-Franchise Supply Customers are determined primarily by the
success of the supply business in entering into contracts to supply customers
with electricity.
 
  Revenues from the supply business increased by (Pounds)16 million (10%) from
(Pounds)154 million for the three months ended June 30, 1995 to (Pounds)170
million for the three months ended June 30, 1996. In the three months ended
June 30, 1996, the number of electricity units supplied increased by 22% but
total revenues produced by the supply business increased by only 10%, because
a majority of the increase in total units supplied was to Non-Franchise Supply
Customers, who are the larger energy users charged at generally lower average
unit prices than those charged to Franchise Supply Customers. Within the
franchise market, the number of electricity units supplied increased by 2% but
this was offset by a reduction in allowable income as set by the Supply Price
Control Formula.
 
 Cost of Sales
 
  Cost of sales increased by (Pounds)15 million (14%) from (Pounds)107 million
in the three months ended June 30, 1995 to (Pounds)122 million in the three
months ended June 30, 1996. This increase was principally the result of an
increase in the supply business cost of sales of (Pounds)15 million reflecting
an increase in purchases of electricity to supply the increase in unit sales
as discussed above.

 Operating Expenses
 
  Operating expenses decreased by (Pounds)2 million (6%) from (Pounds)34
million in the three months ended June 30, 1995 to (Pounds)32 million in the
three months ended June 30, 1996. This decrease was primarily due to a
(Pounds)1 million decrease in maintenance costs and a (Pounds)3 million
decrease in selling, general and administrative costs, which were partially
offset by a (Pounds)2 million increase in depreciation and amortization
resulting from the application of the purchase method of accounting.
 
  The decrease in selling, general and administrative costs resulted in part
from a decrease in certain classes of computer software development costs
which were expensed during the three months ended June 30, 1995 but were
capitalized in the three months ended June 30, 1996, having satisfied the
criteria for capitalization under the Company's accounting policy (see Note 1
to the Consolidated Financial Statements of the Successor Company). The
decrease in selling, general and administrative costs was also due to a
decrease in labor costs resulting from a reduction in personnel. The decrease
in selling, general and administrative costs was partially offset by an
increase in pension costs.
 
 Other Income
 
  Other income increased by (Pounds)2 million from (Pounds)1 million in the
three months ended June 30, 1995 to (Pounds)3 million in the three months
ended June 30, 1996. This increase was primarily attributable to additional
proceeds of (Pounds)1.3 million from the sale by NGG, of which SWEB owned
6.3%, of NGG's pumped storage electricity generation business. See "--
Significant Events."
 
 Interest Expense
   
  Interest expense increased by (Pounds)10 million from (Pounds)3 million in
the three months ended June 30, 1995 to (Pounds)13 million in the three months
ended June 30, 1996, principally as a result of the financing costs associated
with the increased amount of debt issued for the acquisition. The weighted
average balance of debt outstanding during the three months ended June 30,
1996 was (Pounds)632 million at a weighted average interest rate of 7.3%
compared to (Pounds)93 million at 11.6% during the three months ended June 30,
1995.     
 
 Income Taxes
 
  Income taxes decreased by (Pounds)3 million (33%) from (Pounds)9 million in
the three months ended June 30, 1995 to (Pounds)6 million in the three months
ended June 30, 1996. This decrease was primarily attributable to a decrease in
pre-tax income.
 
FISCAL YEAR 1995 COMPARED WITH PRO FORMA FISCAL YEAR 1996
 
 Earnings
 
  Operating income decreased by (Pounds)18 million (13%) from (Pounds)139
million in fiscal year 1995 to (Pounds)121 million in Pro Forma Fiscal Year
1996. This decrease was due to a (Pounds)24 million increase in cost of sales,
partially offset by a (Pounds)4 million increase in operating revenues and a
(Pounds)2 million decrease in operating expenses.
   
  Net income decreased by (Pounds)45 million (48%) from (Pounds)94 million in
fiscal year 1995 to (Pounds)49 million in Pro Forma Fiscal Year 1996. In
addition to the factors discussed in the previous paragraph which reduced
operating income, the decrease in net income was primarily due to increased
after-tax interest expense of (Pounds)37 million principally due to debt
issued for the acquisition.

(1) Represents non-recurring revenues received in fiscal year 1995 for
    installing the telecommunications fiberoptic infrastructure.
 
  Revenues from the supply business increased by (Pounds)1 million from
(Pounds)725 million in fiscal year 1995 to (Pounds)726 million in Pro Forma
Fiscal Year 1996. This increase reflects an increase of (Pounds)11 million in
revenues from the franchise supply market which offset a (Pounds)10 million
reduction in revenues from the non-franchise supply market which was primarily
due to lower unit sales. This increase was the result of an overall increase
in unit sales to supply customers and application of the Supply Price Control
Formula which resulted in an upward inflation adjustment that exceeded the
downward regulatory factor adjustment.
 
  Intra-business revenues decreased by (Pounds)28 million (10%) from
(Pounds)280 million in fiscal year 1995 to (Pounds)252 million in Pro Forma
Fiscal Year 1996 primarily as the result of the decrease in revenues from the
distribution business described above.
 
 Cost of Sales
 
  Cost of sales increased by (Pounds)24 million (5%) from (Pounds)480 million
in fiscal year 1995 to (Pounds)504 million in Pro Forma Fiscal Year 1996. This
increase is principally the result of an increase in the supply business
energy purchase costs of (Pounds)20 million.

 Operating Expenses
 
  Operating expenses decreased by (Pounds)2 million (1%) from (Pounds)157
million in fiscal year 1995 to (Pounds)155 million in Pro Forma Fiscal Year
1996. This decrease was principally due to a reduction in severance costs of
(Pounds)6 million as a result of providing for severance costs under the
purchase method of accounting at the acquisition date and a net decrease in
certain classes of computer software development costs which were expensed
during fiscal year 1995 but were capitalized in Pro Forma Fiscal Year 1996,
having satisfied the criteria for capitalization under the Company's
accounting policy (see Note 1 to the Consolidated Financial Statements of the
Successor Company), partially offset by an increase in net pension costs and
an increase in depreciation and amortization expense.
 
 Interest Expense
   
  Interest expense increased by (Pounds)55 million from (Pounds)11 million in
fiscal year 1995 to (Pounds)66 million in Pro Forma Fiscal Year 1996
principally as a result of the financing costs associated with the increased
amount of debt issued for the acquisition. Interest expense for Pro Forma
Fiscal Year 1996 reflects interest expense recorded in connection with the
acquisition as if the acquisition had occurred on April 1, 1995 and had been
100% financed with short-term borrowings at an interest rate of 6% per year.
However, in fiscal year 1996, the Company retired an aggregate of (Pounds)96
million of debt and converted (Pounds)500 million of debt to equity, and such
retirement and conversion were not reflected in the financial statements for
Pro Forma Fiscal Year 1996. The weighted average balance of debt outstanding
during the Pro Forma Fiscal Year 1996 was (Pounds)876 million ($1,360 million)
at a weighted average interest rate of 7.5% compared to (Pounds)93 million at
11.9% during fiscal year 1995.     
 
 Income Taxes
   
  Income taxes decreased by (Pounds)24 million from (Pounds)50 million in
fiscal year 1995 to (Pounds)26 million in Pro Forma Fiscal Year 1996. This
decrease is primarily attributable to a decrease in pre-tax income.     
 
FISCAL YEAR 1994 COMPARED WITH FISCAL YEAR 1995
 
 Earnings
 
  Operating income increased by (Pounds)17 million (14%) from (Pounds)122
million in fiscal year 1994 to (Pounds)139 million in fiscal year 1995,
primarily due to a (Pounds)28 million increase in operating income from the
distribution business which was partially offset by a (Pounds)9 million
decrease in operating income from the supply business.
 
  Net income increased by (Pounds)6 million (7%) from (Pounds)88 million in
fiscal year 1994 to (Pounds)94 million in fiscal year 1995. The increase was
primarily due to an increase of (Pounds)11 million in after-tax operating
income, an increase of (Pounds)2 million in after-tax interest income and an
increase of (Pounds)1 million in after-tax gain from discontinued operations,
partly offset by a one-time, after-tax loss of (Pounds)8 million on the sale
of the retail appliance business.
 
 Revenues
 
  Operating revenues decreased by (Pounds)32 million (4%) from (Pounds)808
million in fiscal year 1994 to (Pounds)776 million in fiscal year 1995 as

(1) Represents primarily non-recurring revenues received in fiscal year 1995
    for installing the telecommunications fiberoptic infrastructure.
 
  Revenues from the supply business decreased by (Pounds)47 million (6%) from
(Pounds)772 million in fiscal year 1994 to (Pounds)725 million in fiscal year
1995 almost entirely as a result of lower unit sales in the non-franchise
supply market. The impact of the first supply price review was to reduce
revenues from Franchise Supply Customers by approximately (Pounds)3 million,
although additional revenues of (Pounds)14 million were achieved in the
franchise supply market as a result of extinguishing the under-recovery from
fiscal year 1994.
 
 Cost of Sales
 
  Cost of sales decreased by (Pounds)31 million (6%) from (Pounds)511 million
in fiscal year 1994 to (Pounds)480 million in fiscal year 1995. This decrease
was principally the result of a decrease in the amount of energy purchased due
to a reduction in unit sales to Non-Franchise Supply Customers.
 
 Operating Expenses
 
  Operating expenses decreased by (Pounds)18 million (10%) from (Pounds)175
million in fiscal year 1994 to (Pounds)157 million in fiscal year 1995
resulting primarily from a (Pounds)10 million reduction in severance costs and
a (Pounds)10 million reduction in pension costs, partially offset by an
increase of (Pounds)2 million in other expenses.
 
 Income Taxes
 
  Income taxes increased by (Pounds)7 million from (Pounds)43 million in
fiscal year 1994 to (Pounds)50 million in fiscal year 1995 reflecting an
increase in pre-tax income.
 
LIQUIDITY AND CAPITAL RESOURCES
   
  The principal sources of funds during Pro Forma Fiscal Year 1996 were
(Pounds)94 million ($146 million) cash from operations, (Pounds)270 million
($419 million) of proceeds from the disposal of the Company's investment in
NGG, (Pounds)500 million ($776 million) of equity contributions from Southern,
and (Pounds)1,247 million ($1,936 million) of proceeds from the issuance of
short-term debt. During Pro Forma Fiscal Year 1996, the Company invested cash
of (Pounds)1,023 million ($1,589 million) in its acquisition of SWEB, and
(Pounds)59 million ($92 million) in capital expenditures. In addition, the
Company repaid (Pounds)696 million ($1,080 million) of its short-term debt,
paid (Pounds)75 million ($116 million) in dividends related to activities of
SWEB prior to the acquisition, and paid (Pounds)191 million ($297 million) of
dividends related to activities subsequent to the acquisition.     
   
  The principal sources of funds of the Predecessor Company during fiscal year
1995 were (Pounds)100 million ($155 million) cash from operations and
(Pounds)24 million ($37 million) of net additional short-term borrowings.
During fiscal year 1995, the Predecessor Company invested (Pounds)68 million
($106 million) in capital expenditures, paid dividends of (Pounds)30 million
($47 million), and repurchased common stock totaling (Pounds)103 million ($160
million).     
 
                                      32

  The principal sources of funds of the Predecessor Company during fiscal year
1994 were (Pounds)236 million ($366 million) cash from operations. During
fiscal year 1994, the Predecessor Company invested (Pounds)61 million ($95
million) in capital expenditures, purchased (Pounds)15 million ($23 million)
of investments, paid dividends of (Pounds)26 million ($40 million) and reduced
its short-term borrowings by (Pounds)37 million ($57 million).     
   
  At March 31, 1996, the Company had negative working capital of (Pounds)649
million ($1,008 million), compared to positive working capital of the
Predecessor Company of (Pounds)14 million ($22 million) at March 31, 1995. The
working capital deficit at March 31, 1996 is primarily the result of the
initial financing structure of the acquisition of SWEB.     
 
  To meet short-term cash needs and contingencies, the Company had
approximately (Pounds)20 million of cash and cash equivalents, on a
consolidated basis, at the end of fiscal year 1996.
 
  The Company's sole investment and only significant asset is the entire share
capital of SWEB. The Company is therefore dependent upon dividends from SWEB
for its cash flow. The Company's primary need for liquidity is to pay interest
on its debt, and the Company expects to receive sufficient amounts of
dividends from SWEB to make such payments. SWEB can make distributions of
dividends to the Company under English law to the extent that it has
distributable reserves, subject to the retention of sufficient financial
resources to conduct its supply and distribution businesses as required by its
PES license. The Company believes that sufficient distributable reserves will
exist at SWEB to allow for any and all cash flow generated at SWEB through
operations to be distributed to the Company through dividends to the Company.
SWEB's need for liquidity is to pay interest on its debt and to fund its costs
of operations and capital expenditure programs.
 
  The Company, on a consolidated basis, has four primary sources of liquidity
available to it. SWEB's internal source of funds is cash from operations,
which totalled (Pounds)74 million in Pro Forma Fiscal Year 1996. SWEB has a
(Pounds)275 million, three-year revolving credit facility provided by a
banking consortium. SWEB also has five bilateral committed loan facilities
totaling (Pounds)120 million and several uncommitted loan facilities totalling
(Pounds)105 million provided by banking institutions. At the end of fiscal
year 1996, a total of (Pounds)292 million had been drawn from these
facilities.
 
  Demand for electricity in Great Britain, in general, and in SWEB's Franchise
Area, in particular, is seasonal, with demand being higher in the winter
months and lower in the summer months. SWEB bills its Franchise Supply
Customers on a staggered quarterly basis while it is generally required to pay
related expenses (principally the cost of purchased electricity) on 28-day
terms. However, approximately 40% of the Franchise Supply Customers settle
their accounts using regular payment plans which either allow prepayment or
spreading of the cost of their annual bill evenly throughout the year. A
majority of SWEB's contracts for supply of electricity to Non-Franchise Supply
Customers require SWEB's customers to pay a fixed price per unit, while the
cost of supply to SWEB from the Pool, if not covered by hedging mechanisms,
varies throughout the year, generally being higher in winter months and lower
in summer months. SWEB balances the effect of these timing and cyclical
influences on its working capital needs with drawings under its available
credit facilities.
 
  The distribution business charges licensed suppliers monthly for the
provision of its distribution services. The majority of the distribution
revenue is received from SWEB's supply business. In the case of second-tier
suppliers to Non-Franchise Supply Customers in SWEB's Franchise Area,
distribution charges are billed directly to the suppliers on a monthly basis.
 
  SWEB's capital expenditures are primarily related to the distribution
business and include expenditures for load-related, non-load-related and non-
operational capital assets. Load-related capital expenditures are largely
required by new business growth. Customer contributions are normally received
where capital expenditures are made to extend or upgrade service to customers
(except to the extent that such capital expenditures are made to enhance
SWEB's distribution network generally). Non-load-related capital expenditures
include asset replacement which is expected to continue until at least the
next decade. Other non-load-related expenditures include system upgrade work
that provides for load growth and has the additional benefit of improving
network security and
 
                                      33
<PAGE>
 
reliability. Non-operational capital expenditures are for assets such as
generation, fixtures and equipment. For the fiscal years 1994, 1995 and 1996,
capital expenditures, net of customer contributions, were (Pounds)61 million,
(Pounds)68 million and (Pounds)60 million, respectively. SWEB expects total
capital expenditures, net of customer contributions, to be approximately
(Pounds)75 million in fiscal year 1997. The increase from prior years is due
primarily to increased capitalization of significant expenditures on new
information technology systems related principally to a new customer
information system. The Company expects the level of information technology
expenditure to return to the previous lower levels when the new billing system
is implemented. The Company expects the levels of load-related and non-load-
related capital expenditures to remain stable relative to current levels for
several years. Since its inception, SWEB has generated sufficient funds from
operations to meet its capital expenditure requirements and is expected to do
so in the future.
 
  The Company currently has a (Pounds)325 million term loan outstanding that
is scheduled to mature in February 1997. The Company does not intend to create
reserves to repay the loan at maturity. Thus, it is anticipated that the
outstanding principal of the loan will be repaid from the proceeds of
refinancings. The net proceeds of the Offering will be used to partially repay
the term loan. The Company anticipates additional capital markets borrowings,
the proceeds of which will be used to repay the remainder of the term loan and
which the Company expects will have the effect of extending the maturities of
the Company's debt. At the end of fiscal year 1996, the Company also had
outstanding approximately (Pounds)27 million of loan notes issued as part of
the Company's acquisition of SWEB. Holders of the loan notes have the right to
require the Company to redeem the loan notes on semi-annual interest payment
dates. The Company intends to meet those redemption obligations with cash on
hand.
 
  To assure the stability of future interest charges, the Company has entered
into a series of interest rate swap transactions with total notional amounts
of (Pounds)450 million. These transactions have maturities of between 5 and 10
years. The Company expects to effectively reverse the swap agreements at the
time of issuance of additional fixed rate debt.
 
  The Company does not have any foreign currency hedging contracts in place;
however, it does intend to swap the US dollar liabilities associated with the
Offering back to pounds sterling to effectively hedge the currency risk
associated with the interest on and principal of the Senior Notes.
   
  Management believes that cash flow from operations, together with its
existing sources of credit, the proceeds of this Offering and other future
refinancings, will provide sufficient financial resources to meet the
Company's capital needs and expenditure requirements for at least the next
twelve months. Management further believes that cash flow from operations,
together with its existing sources of credit and the proceeds from future
refinancings, will provide sufficient financial resources to meet the
Company's projected capital needs and other expenditure requirements for the
foreseeable future. However, there can be no assurance that future
refinancings will be available to the Company or that they will be on terms
favorable to the Company.     
   
  The financial statements included elsewhere in this Prospectus have not been
prepared in accordance with the policies of Statement of Financial Accounting
Standards No. 71, "Accounting for the Effects of Certain Types of Regulation"
("SFAS No. 71"). This pronouncement, under which most US electric utilities
report financial statements, applies to entities which are subject to cost-
based rate regulation. By contrast, SWEB is not subject to rate regulation,
but rather is subject to price cap regulation and therefore the provisions of
SFAS No. 71 do not apply. Financial statements presented in accordance with
SFAS No. 71 contain deferred items which have not yet been included in rates
charged to customers in compliance with the respective regulatory authorities,
but which would have been included in the income statement of enterprises in
general under US GAAP. The accompanying financial statements of the Company do
not contain such deferrals.

                                   BUSINESS
 
GENERAL
   
  The Company is a wholly-owned subsidiary of Holdings, of which 75% is owned
indirectly by Southern and 25% is owned indirectly by PP&L Resources. The
Company was incorporated as a public limited company under the laws of England
and Wales in June 1995 as a vehicle for the acquisition of SWEB, one of the 12
RECs in England and Wales licensed to distribute, supply and, to a limited
extent, generate electricity. In September 1995, the Company gained effective
control of SWEB, having acquired approximately 84% of its shares. The Company
subsequently replaced SWEB's board of directors and certain senior managers
with officers and employees of companies from within the Southern Company
system. In November 1995, the Company acquired the remaining shares of SWEB.
The Company's sole investment and only significant asset is the entire share
capital of SWEB, which is headquartered in Bristol, England. At June 30, 1996
the Company had consolidated assets of (Pounds)1.659 billion ($2.576 billion).
    
  SWEB's two main business lines are the distribution of electricity and
supply of electricity to approximately 1.3 million customers in its Franchise
Area in southwest England. The distribution business and the supply business
are distinct business segments and produced operating income of (Pounds)112
million ($174 million) and (Pounds)15 million ($23 million), respectively, in
Pro Forma Fiscal Year 1996, representing substantially all of the Company's
consolidated operating income in that pro forma fiscal year.
 
  SWEB's Franchise Area covers approximately 5,560 square miles extending from
Bristol and Bath in the northeast, 188 miles southwest along the peninsula to
Land's End and 28 miles beyond to the Isles of Scilly, and has a resident
population of approximately 2.8 million. The South West of England, of which
the Franchise Area forms the greater part, has benefitted from economic growth
(as measured by GDP) which exceeded the UK average from 1991 through 1995 and
has also benefited from an average unemployment rate during calendar year 1995
of approximately 6.9% which was below the UK average of 8.2% according to a
recent study by Cambridge Econometrics. The largest cities and towns in SWEB's
Franchise Area are Bath, Bristol, Exeter, Plymouth and Taunton. Business
activity is generally concentrated in the population centers around Bristol,
Bath and Plymouth. The Bristol and Bath area is served by the M4 and M5
motorways, a strong rail network, the rail link between Bristol and London and
a commercial port at Avonmouth.
 
  The Company and SWEB have undertaken to make SWEB a more focused and
competitive company concentrating on the main electricity businesses of
distribution and supply. Several businesses not related to distribution and
supply have been sold, and the remaining ancillary businesses have been
redirected to focus on support for the main electricity businesses.
 
  The key goals which the Company and SWEB are pursuing include cost savings
and improved customer service. The objective of cost savings is to increase
profitability. Cost savings have been realized through programs of staff
reduction and working with the unions on a program of job redesign leading to
changes in work practices. The objective of improved customer service is to
prepare for the increasingly competitive aspects of the supply business by
building customer loyalty through improvements in system performance and
responsiveness to customers' needs, and to meet and exceed the performance
criteria established by the Regulator. Improvements in customer service are
being pursued in part through improvements in system performance, as measured
primarily by reductions in customer minutes lost and overall number of
outages.
 
OVERVIEW OF THE ELECTRIC UTILITY INDUSTRY IN GREAT BRITAIN
 
  In 1990, the electric utility industry in Great Britain was privatized, and
SWEB was created along with the other 11 RECs. In connection with the
privatization, distribution assets in England and Wales, previously owned
indirectly by Her Majesty's Government, were allocated among the RECs,
licensing requirements were established for the RECs and price controls were
implemented in the areas of distribution and supply. In England and Wales,
generation assets (other than nuclear facilities) were allocated to two
generating companies, and the
 
                                      35
<PAGE>
 
high voltage transmission assets were allocated to The National Grid Company
plc ("NGC," which is wholly owned by NGG). See "The Electric Utility Industry
in Great Britain."
 
  The high voltage transmission system in England and Wales, which is
generally referred to as the "national grid," carries the generated
electricity in bulk from the power stations to the regional and local
distribution systems. This transmission system is owned and operated by NGC.
 
  Distributors transfer electricity over their networks, generally at lower
voltage than the national grid, from supply points on the national grid to
final consumers. The distribution systems in England and Wales are owned by
the 12 RECs. Virtually all customers in England and Wales are connected to the
distribution system of the RECs and have no choice as to the distribution
system from which they receive their electricity. Distribution prices charged
by the RECs are regulated by the Distribution Price Control Formula.
   
  Suppliers sell electricity to end users. Each REC is required to have a PES
license which authorizes it to supply electricity to any customers within its
franchise area. Electricity customers fall into two categories, Franchise
Supply Customers and Non-Franchise Supply Customers. Prices for supply of
electricity to Franchise Supply Customers are regulated by the Supply Price
Control Formula. Such price control is currently scheduled to expire on March
31, 1998, at which time the franchise supply market is expected to be open to
any competitors who have obtained the necessary license, which is generally
referred to as a "second tier license." Non-Franchise Supply Customers may
already be supplied by anyone who has obtained a second tier license. Such
second tier suppliers, including SWEB, compete for business nationally and at
prices determined by competitive bids or negotiation.     
 
  At the time of privatization, the Pool was established for bulk trading of
electricity in England and Wales between generators and suppliers. The Pool
reflects two principal characteristics of the physical generation and supply
of electricity from a particular generator to a particular supplier. First, it
is not possible to trace electricity from a particular generator to a
particular supplier. Second, it is not practicable to store electricity in
significant quantities, creating the need for a constant matching of supply
and demand. Subject to certain exceptions, all electricity generated in
England and Wales must be sold and purchased through the Pool. All licensed
generators and suppliers must become signatories to a pooling and settlement
agreement, which governs the constitution and operation of the Pool and the
calculation of payments due to and from generators and suppliers (the "Pooling
and Settlement Agreement"). The Pool also provides centralized settlement of
accounts and clearing. Prices for electricity are set by the Pool daily for
each half hour of the following day based on the bids of the generators and a
complex set of calculations matching supply and demand and taking account of
system stability, security and other costs. See "The Electric Utility Industry
in Great Britain--The Structure of the Electricity Industry in Great Britain--
The Pool."
 
SWEB'S MAIN BUSINESSES
 
DISTRIBUTION BUSINESS
 
  SWEB's distribution business is the ownership, management and operation of
the electricity distribution network within SWEB's Franchise Area. The primary
activity of the distribution business is the receipt of electricity from the
national grid transmission system and its distribution to end users of
electricity that are connected to SWEB's power lines. Virtually all
electricity supplied (whether by SWEB's independent supply business or by
other suppliers) to consumers in SWEB's Franchise Area is transported through
its distribution network, thus providing SWEB with distribution volume that is
stable from year to year. As a holder of a PES license, SWEB is subject to a
price cap regulatory framework that provides economic incentives to increase
the number of units of electricity distributed and to operate in a more cost-
efficient manner. See "The Electric Utility Industry in Great Britain."
 
  SWEB's distribution business has grown in both its customer base and in the
number of units distributed, primarily reflecting economic growth in the South
West of England. At March 31, 1996 SWEB had experienced
 
                                      36
<PAGE>
 
a 5-year compound annual growth rate of 0.8% in customers and a 5-year
compound annual growth rate of 1.6% in units distributed.
 
 Strategy
 
  Since being acquired by the Company, SWEB has reviewed and refined its
distribution strategy and has established key goals of cost savings and
improved customer service.
 
  Staff reductions play a key role in cost savings. SWEB has implemented a
plan of voluntary and other staff reductions to reduce the number of employees
by 704 (mainly in the distribution business and representing 21% of staff at
the time of the acquisition of SWEB by the Company), of which 460 reductions
occurred prior to June 30, 1996. Part of these reductions are made possible
due to new work practices which SWEB has developed with the cooperation of
SWEB's unions. Team restructuring in the engineering department of SWEB has
commenced, and the establishment of multi-skilled independent teams has been
achieved. In addition, management restructuring has produced a flatter
organizational structure by reducing management levels from seven to three.
 
  Improvements in customer service in the distribution business, if achieved,
are part of SWEB's strategy to retain Franchise Supply Customers in its
Franchise Area after March 31, 1998 and are expected to enable SWEB to meet or
exceed the performance criteria established by the Regulator who is
responsible for setting the performance standards of the RECs. SWEB believes
that achieving these goals is important both for building customer loyalty for
the benefit of the supply business by maintaining and improving customer
satisfaction and for maintaining good relations with the Regulator.
Improvements in customer service are being pursued, in part, through
improvements in system performance, measured primarily in terms of customer
minutes lost and overall number of outages. To that end, several initiatives
are being pursued including:
 
  . eliminating the backlog of tree-trimming near distribution lines;
 
  . implementing a program of network improvements that will create more dual
    routing;
 
  . reordering the priorities of SWEB's capital expenditure program to focus
    on improving system reliability; and
 
  . introducing a single-number telephone call center supported by new
    computerized information systems which allows employees at the call
    center (including advisory engineers) to initiate engineering work orders
    to satisfy customer needs for repairs or maintenance of the distribution
    network.
 
 Customers
 
  Most of SWEB's distribution customers are Franchise Supply Customers. This
customer group consists predominantly of residential and small commercial
consumers which provides SWEB a stable customer base. SWEB's fastest growing
category of distribution customers, in terms of units distributed and
revenues, is large commercial and small industrial customers. Commercial
activity of SWEB's customers is mostly service based and includes financial
services, electronics and technology-related businesses. SWEB also distributes
electricity to industrial concerns in its Franchise Area. The principal
activities of SWEB's largest distribution customers include china clay
extraction, ship repair, fertilizer production, aerospace, defense
engineering, cement and paper manufacturing and water supply. SWEB's 20
largest distribution customers in its Franchise Area accounted for 9.8% of
total electricity distributed by SWEB in fiscal year 1996 in terms of units
distributed, with no single customer exceeding 2.3% of total electricity
distributed. The following table sets out details of SWEB's distribution
customers, units distributed and distribution revenues.

 Distribution Facilities
 
  Electricity is transported across the national grid transmission system at
400kv or 275kv to eight grid supply points within SWEB's distribution network,
where it is transformed by SWEB to 132kv and enters SWEB's distribution
system. Electricity is also transported to two national grid supply points
located in neighboring RECs' franchise areas, which are connected to SWEB's
distribution system by overhead lines and underground cables. Substantially
all electricity which enters SWEB's system is received at these ten grid
supply points.
 
  At March 31, 1996, SWEB's electricity distribution network (excluding
service connections to consumers) included overhead lines and underground
cables at the operating voltage levels indicated in the table below:

  Electricity is received by customers at various voltages depending upon
their requirements. At March 31, 1996, SWEB's distribution system was
connected to over 1.3 million customers. In providing service connections to
customers and to street lighting, traffic lights and other installations from
its network, SWEB uses lengths of overhead lines and underground cables in
addition to those referred to above.
 
  Operation and control of SWEB's distribution system is continuously
monitored and coordinated from two control centers located in Bristol and
Exeter. The Exeter control center is responsible for the entire 132kv network.
Responsibility for the 33kv and 11kv networks is divided between the two
control centers. A telecontrol system has been implemented to provide remote
information gathering and to provide remote operation of 132kv and selected
33kv and 11kv switchgear. See also the map on the inside cover page of this
Prospectus.
 
SUPPLY BUSINESS
 
  SWEB's supply business is selling electricity to end users, purchasing such
electricity, primarily from the Pool, and arranging for its distribution to
those end users. SWEB's supply business is comprised predominantly of
supplying Franchise Supply Customers. In fiscal year 1996, these customers
accounted for approximately 82% of all units of electricity supplied by SWEB.
SWEB's exclusive right to supply these customers is scheduled to continue,
subject to price regulation, until March 31, 1998, at which time competition
to supply Franchise Supply Customers is scheduled to commence. Supply prices
for these customers are regulated, and SWEB's prudent costs of purchasing and
delivering electricity and hedging the purchase price are charged to them.
 
  The market to supply Non-Franchise Supply Customers is fully competitive,
principally with other RECs and the major generators. Non-Franchise Supply
Customers are typically supplied through individual contracts for a duration
of one to two years with competitively bid or negotiated prices.
 
 Strategy
 
  Since its acquisition by the Company, SWEB has completed a review of the
supply market, established new goals for its supply business and adopted new
strategies for achieving those goals. The key goals established are the
retention of its current Franchise Supply Customers as supply customers after
March 31, 1998 and the increase of SWEB's share of electricity supplied to
Non-Franchise Supply Customers both inside and outside SWEB's Franchise Area.
As a result of this strategy, SWEB expects to supply a larger portion of units
to Non-Franchise Supply Customers than in fiscal year 1996.
 
  SWEB's strategy for retaining its Franchise Supply Customers is to build
customer loyalty and to offer competitive prices. SWEB seeks to build customer
loyalty by providing superior service, including reliable distribution
service, responsive service in dealing with billing and other matters and
providing other service enhancements. SWEB is revamping its marketing, sales
and customer service operations under the direction of Executive Directors of
SWEB transferred from other companies within the Southern Company system, who
are experienced in competitive electricity marketing.
 
  Initiatives in relation to the Franchise Supply Customers include:
     
  . a single-number, local rate, telephone service call center (which has
    been in place since April 1996);     
     
  . a state-of-the-art billing and customer service system which will enable
    employees at the call center to act on or resolve customer billing and
    account inquiries on line during their calls (which should be operational
    in 1998); and     
     
  . a restructuring of meter reading operations which should enable almost
    all meters to be read quarterly, thereby reducing estimated readings
    (which has already begun and is expected to be completed in 1997). (In
    Great Britain, most meters are located within structures, and meter
    readers are required to obtain access from occupants in order to read
    meters. As a result, actual readings were often obtained only on an
    annual or biennial basis.)     
 
                                      39
<PAGE>
 
  SWEB's strategy for expanding its market share of electricity sold to Non-
Franchise Supply Customers both inside and outside its Franchise Area is to
offer competitive pricing and, with respect to its Non-Franchise Supply
Customers inside its Franchise Area, to build customer loyalty through the
measures described above and through the measures described in "--Distribution
Business."
 
  Additional initiatives to support growth in market share in the Non-
Franchise Supply Customer market include:
     
  . the expanded use of account managers for Non-Franchise Supply Customers
    (which has already begun);     
     
  . increasing the number of proposals and bids made to customers and
    potential customers (which has already begun);     
     
  . development of an integrated contract customer sales, electronic
    registration and marketing system with full customer life-cycle
    management and tracking facilities (which is scheduled to be completed by
    January 1997); and     
     
  . further enhancement of a competitive price setting system used to
    determine appropriate contract supply prices (which is also scheduled to
    be completed by January 1997).     
 
 Franchise Supply Market
 
  Under the terms of its PES license, SWEB currently holds the right to supply
approximately 1.3 million Franchise Supply Customers within its Franchise
Area. See "Business--General." During fiscal year 1996, sales to Franchise
Supply Customers represented 82% of total units supplied by SWEB and produced
86% of SWEB's total supply revenue.
 
  The exclusive right to supply Franchise Supply Customers is scheduled to end
on March 31, 1998, at which time all supply customers will have the ability to
choose their electricity supplier. SWEB intends to retain its market share of
these customers by providing superior customer service and competitive
pricing. In fiscal year 1995, SWEB met or exceeded the Regulator's overall
standards of performance in 99.9% of the services measured by the Regulator.
See "--Strategy."
 
 Non-Franchise Supply Market
 
  In addition to competing for Non-Franchise Supply Customers in its Franchise
Area, SWEB holds a second tier license to compete with the RECs and other
suppliers to provide electricity to Non-Franchise Supply Customers outside its
Franchise Area. At the end of fiscal year 1996, SWEB had approximately 1,500
Non-Franchise Supply Customers, consisting primarily of large commercial and
industrial accounts. Revenue from these customers during fiscal year 1996
accounted for only 14% of total supply revenues. SWEB has achieved a
significant increase in the number of Non-Franchise Supply Customers since the
Company acquired SWEB.
 
SWEB'S OTHER BUSINESS ACTIVITIES
 
  SWEB also has ancillary business activities that support its main
electricity distribution and supply businesses, including electricity
generation and gas supply. SWEB owns generating assets with 24MW of capacity
used to back up the distribution network as well as minority investments in
windfarms and a 7.7% interest in Teesside Power Limited, owner of a 1,875 MW
combined cycle plant. SWEB has a 75% joint venture interest in a supplier of
gas and derives small amounts of revenue from the lease of fibers within the
fiber optic cables carried on its distribution network. SWEB also markets and
develops property no longer used in the main electricity businesses.

RISK MANAGEMENT
 
  Because SWEB's distribution business does not involve the purchase and sale
of electricity, SWEB's risk management efforts are focused on the supply
business which is exposed to Pool price volatility.
 
  Regulations governing the franchise supply market permit the pass-through to
customers of prudent costs which include the cost of arrangements such as
contracts for differences ("CFDs") to hedge against Pool price volatility.
CFDs are contracts predominantly between generators and suppliers which fix
the price of electricity for a contracted quantity of electricity over a
specific time period. Differences between the actual price set by the Pool and
the agreed prices give rise to difference payments between the parties to the
particular CFD. At the present time, SWEB's forecast franchise supply market
demand for fiscal year 1997 is substantially hedged through various types of
agreements including CFDs.
 
  The most common contracts for supply to Non-Franchise Supply Customers are
for a twelve-month term and contain fixed rates. SWEB is exposed to two
principal risks associated with such contracts: load shape risk (the risk
associated with a shift in the customer's usage pattern, including absolute
amounts demanded and timing of amounts demanded) and purchasing price risk
(the cost of purchased electricity relative to the price received from the
supply customer). SWEB employs risk management methods to maximize its return
consistent with an acceptable level of risk. Generally load shape risk
decreases as SWEB's portfolio of supply customers in the non-franchise supply
market increases. SWEB hedges purchasing price risk by employing a variety of
risk management tools, including management of its supply contract portfolio,
hedging contracts and other means which mitigate risk of future Pool price
volatility.
 
  SWEB's ability to manage its purchasing price risk depends, in part, on the
future availability of properly priced risk management mechanisms such as
CFDs. No assurance can be given that an adequate, transparent market for such
products will in fact be available.
 
UK ENVIRONMENTAL REGULATION
 
  SWEB's businesses are subject to numerous regulatory requirements with
respect to the protection of the environment. The Electricity Act 1989 (the
"Electricity Act") obligates the UK Secretary of State for Trade and Industry
(the "Secretary of State") to take into account the effect of electricity
generation, transmission and supply activities upon the physical environment
in approving applications for the construction of generating facilities and
the location of overhead power lines. The Electricity Act requires SWEB to
have regard to the desirability of preserving natural beauty and the
conservation of natural and man-made features of particular interest, when it
formulates proposals for development in connection with certain of its
activities. The Company mitigates the effects its proposals have on natural
and man-made features and is required to carry out an environmental assessment
when it intends to lay cables, construct overhead lines or carry out any other
development in connection with its licensed activities. SWEB also has produced
an Environmental Policy Statement which sets out the manner in which it
intends to comply with its obligations under the Electricity Act.
 
  The Environmental Protection Act 1990 addresses waste management issues and
imposes certain obligations and duties on companies which handle and dispose
of waste. Some of SWEB's distribution activities produce waste, but SWEB
believes that it is in compliance with the applicable standards in such
regard.
 
  Possible adverse health effects of electromagnetic fields ("EMFs") from
various sources, including transmission and distribution lines, have been the
subject of a number of studies and increasing public discussion. The
scientific research currently is inconclusive as to whether EMFs may cause
adverse health effects. The only UK standards for exposure to power frequency
EMFs are those promulgated by the National Radiological Protection Board and
relate to the levels above which non-reversible physiological effects may be
observed. SWEB fully complies with these standards. However, there is the
possibility that passage of legislation and change of regulatory standards
would require measures to mitigate EMFs, with resulting increases in capital
and operating costs. In addition, the potential exists for public liability
with respect to lawsuits brought by plaintiffs alleging damages caused by
EMFs.
 
                                      41
<PAGE>
 
  SWEB believes that it has taken and continues to take measures to comply
with the applicable laws and governmental regulations for the protection of
the environment. There are no material legal or administrative proceedings
pending against SWEB or the Company with respect to any environmental matter.
 
EMPLOYEES
 
  SWEB had 3,178 employees (3,079 full time equivalent) and the Company had no
employees at the end of fiscal year 1996. At June 30, 1996, SWEB had 2,880
employees (2,785 full time equivalent). Of SWEB's employees, 95% are
represented by labor unions. All SWEB employees who are not party to a
personal employment contract are subject to a collective bargaining agreement
called The Electricity Business Agreement. This Agreement may be amended by
agreement between SWEB and the unions and is terminable with 12 months notice
by either side. SWEB is currently holding discussions with the unions to
introduce a separate collective bargaining agreement to include meter reading
staff. SWEB believes that its relations with its employees are favorable.
 
PROPERTY
 
  The Company through a subsidiary of SWEB owns the freehold of its principal
executive offices in Bristol. SWEB has both network and non-network land and
building.
 
NETWORK LAND AND BUILDINGS
 
  At March 31, 1996 SWEB had freehold and leasehold interests in approximately
12,000 network properties, comprising principally sub-station sites. The
recorded cost of total network land and buildings at March 31, 1996 was
(Pounds)62 million. SWEB owns, directly or indirectly, the freehold of such
land and buildings.
 
NON-NETWORK LAND AND BUILDINGS
 
  At March 31, 1996 SWEB had freehold and leasehold interests in non-network
properties comprising chiefly offices, former retail outlets, depots,
warehouses and workshops. The recorded cost of total non-network land and
buildings at March 31, 1996 was (Pounds)40.3 million.
 
  The number of properties in each category is:

                THE ELECTRIC UTILITY INDUSTRY IN GREAT BRITAIN
 
THE STRUCTURE OF THE ELECTRICITY INDUSTRY IN GREAT BRITAIN
 
  The electric utility industry in Great Britain consists of the following
activities:
 
Generation: the production of electricity at power stations;
 
Transmission:
            the bulk transfer of electricity across a high voltage
            transmission system;
 
Distribution:
            the transfer of electricity from the high voltage transmission
            system and its delivery, across low voltage distribution systems,
            to consumers; and
 
Supply:     the bulk purchase of electricity by suppliers and its sale to
            consumers.
 
INDUSTRY STRUCTURE
 
  Great Britain has two separate but connected markets, each with a different
commercial framework. In England and Wales electricity is produced by
generators, the largest of which are National Power, PowerGen and Nuclear
Electric, a subsidiary of the recently privatized British Energy. Electricity
is transmitted through the national grid transmission system by NGC and
distributed by the twelve RECs in their respective franchise, or authorized,
areas. Most customers are currently supplied with electricity by their local
REC, although there are other suppliers holding second tier supply licenses,
including other generators and RECs, who can compete to supply larger
customers in that REC's authorized area.
 
  In Scotland there are two vertically integrated companies, Scottish Power
and Hydro-Electric, each generating, transmitting, distributing and supplying
electricity within their respective franchise areas as well as competing to
supply electricity elsewhere. Scottish Nuclear, another subsidiary of British
Energy, sells all the electricity it generates to Scottish Power and Hydro-
Electric under the Nuclear Energy Agreement.
 
  The interconnection between the two transmission systems, owned by Scottish
Power and NGC, is capable of transferring electricity between Scotland and
England and Wales. There is also an interconnection with France, owned by NGC
and Electricite de France, through which electricity can be transferred
between the transmission systems of France and England and Wales.
 
  Virtually all electricity generated in England and Wales is sold by
generators and bought by suppliers through the Pool. A generator which is a
Pool member and also a licensed supplier must nevertheless sell all the
electricity it generates into the Pool, and purchase all the electricity which
it supplies from the Pool. Because Pool prices fluctuate, generators and
suppliers may enter into bilateral arrangements, such as CFDs, to provide a
degree of protection against such fluctuations.
 
  There is no equivalent to the Pool in Scotland, but Scottish Power and
Hydro-Electric are obligated by their licenses to offer electricity for sale
to second tier suppliers. They are also required to provide access to their
transmission and distribution systems on a non-discriminatory basis to
competing suppliers and generators.
 
INDUSTRY BACKGROUND
 
  The industry structure described above was put in place in March 1990. At
the same time, a licensing regime was introduced for the electricity industry
both in England and Wales and in Scotland. The Regulator was first appointed
in 1989.
 
  The RECs, which at that time collectively owned NGG, NGC's holding company,
were privatized in December 1990. National Power and PowerGen were privatized
in March 1991 (with the balance of the UK Government's holding being sold in
March 1995), Scottish Power and Hydro-Electric were privatized in June 1991
and British Energy was privatized in July 1996. NGG was listed on the London
Stock Exchange in
 
                                      43
<PAGE>
 
December 1995. Since the summer of 1995, seven of the RECs have been acquired
by other companies. In particular, SWEB was acquired by the Company in
September 1995.
 
  In 1990, the vast majority of generating capacity was owned by three
generators. However, since that time competition in generation has increased
as RECs and other new entrant generators have constructed new plant and as
imports through the interconnections with Scotland and France have grown. In
addition, pursuant to undertakings given to the Regulator, National Power and
PowerGen have disposed of an aggregate of 6,000 MW of plant to Eastern Group
plc (a REC holding company which was recently acquired by Hanson PLC).
 
  Competition in supply has also been progressively introduced both in England
and Wales and in Scotland. The RECs in England and Wales, and Scottish Power
and Hydro-Electric in Scotland, are subject to competition from second tier
suppliers for the supply of electricity to larger customers in their
respective franchise areas. Under the current licensing regime, all
electricity customers in Great Britain, including domestic customers, are
scheduled to be able to choose their electricity supplier from April 1, 1998.
 
DISTRIBUTION OF ELECTRICITY
 
  Each of the RECs is required to offer terms for connection to its
distribution system to any person, for use of its distribution system to any
authorized electricity operator and for the provision of top-up and stand-by
supplies to any person. In providing use of its distribution system, a REC
must not discriminate between its own supply business and that of any other
authorized electricity operator, or between those of other authorized
electricity operators; nor may its charges differ except where justified by
differences in cost. Similar principles apply to the provision of top-up and
stand-by supplies of electricity, and in the carrying out of connection works.
Disputes over the terms of offers may be determined by the Regulator.
 
  Most revenue of the distribution business is controlled by a formula based
on P+RPI-Xd where Xd is currently 3% (the "Distribution Price Control
Formula"). P reflects the previous maximum average price per unit of
electricity distributed. RPI reflects the percentage change in the Retail
Price Index between the previous year and the current year. The Xd factor is
established by the Regulator following review. This formula determines the
maximum average price per unit of electricity distributed (in pence per
kilowatt hour) which a REC is entitled to charge. This price, when multiplied
by the expected number of units to be distributed, determines the expected
distribution revenues of the REC for the relevant year. The Distribution Price
Control Formula permits RECs to partially retain additional revenues due to
increased distribution of units and allows for a pound-for-pound increase in
operating income for efficient operations and reduction of expenses. The
current Distribution Price Control Formula has been in effect since April 1,
1996 and applies for the four year period ending March 31, 2000.
 
  On August 11, 1994, the Regulator announced the results of a review of the
Distribution Price Control Formula. A one-time reduction in the distribution
charges of all the RECs was made with effect from April 1, 1995 and ranged
from 11% to 17% (the reduction in SWEB's case being 14%), in each case before
allowing for inflation. In addition, the Regulator halved from 100% to 50% the
weight of units in the Distribution Price Control Formula and allocated the
remaining 50% to the number of customers. The stated intention of the
Regulator in introducing this change was "to remove any artificial incentive
on the companies to sell more electricity, while retaining a general incentive
for companies to seek out and meet the needs of their customers." In the light
of information concerning the financial position of the RECs that emerged
during the course of the unsuccessful bid by Trafalgar House plc for Northern
Electric plc (one of the RECs), the Regulator further reduced distribution
charges of all the RECs with effect from April 1, 1996 ranging from 10% to 13%
(the reduction in SWEB's case being 11%), in each case before allowing for
inflation.
 
  The Distribution Price Control Formula is expected to be further reviewed
with effect from April 1, 2000. A REC may seek disapplication of its
Distribution Price Control Formula with effect from that date by request to
the Regulator. If the Regulator wishes to refuse the request, he must refer it
to the Monopolies and Mergers Commission ("MMC").
 
                                      44
<PAGE>
 
  In setting the distribution charges each year, the holder of a PES license
will have to make a projection of the permitted maximum charge per unit
distributed in that year. The projection will have to take account of
forecasts of units distributed, distribution losses and the actual change in
RPI. Failure to forecast accurately may result in over or under charging; this
is taken into account in the following year through a correction factor in the
price control formula. If a REC has overcharged in the previous year, the
maximum average charge per unit distributed is reduced by an amount to reflect
the excess income received, to which is added interest. In the event of
undercharging, the Distribution Price Control Formula allows the licensee to
recover the shortfall in income plus interest.
 
  If, in any year, the average charge per unit distributed exceeds the
permitted maximum average charge per unit distributed by more than 3%, then,
in the next following year, the REC may not increase distribution charges
unless it has satisfied the Regulator that the average charge per unit in that
next following year is not likely to exceed the permitted maximum average
charge. If, in respect of any two successive years, the sum of the amounts by
which the average charge per unit distributed has exceeded the permitted
maximum average charge per unit distributed in the second of those years is
more than 4% of that permitted maximum average charge, then, in the next
following year, the REC may be required by the Regulator to adjust its charges
so that they fall within the maximum permitted average charge. If, in respect
of two successive years, the licensee undercharges by more than 10% of the
maximum average charge, the Regulator may, by directions to the licensee,
limit the amount by which such undercharging may be recovered.
 
ELECTRICITY SUPPLY
 
  Subject to minor exceptions, all electricity customers in Great Britain must
be supplied by a licensed supplier. Licensed suppliers purchase electricity
and make use of the transmission and distribution networks to achieve delivery
to customers' premises.
 
  There are two types of licensed suppliers; public electricity (or first
tier) suppliers ("PESs"); and second tier suppliers. PESs are the RECs,
Scottish Power and Hydro-Electric each supplying in its respective franchise
area. Second tier suppliers include National Power, PowerGen, Nuclear
Electric, Scottish Power, Hydro-Electric and other PESs supplying outside
their respective franchise areas. There are also a number of independent
second tier suppliers.
 
  At present, a Franchise Supply Customer can only buy electricity from the
PES authorized to supply the relevant franchise area. Franchise Supply
Customers typically include domestic and small commercial and industrial
customers. Non-Franchise Supply Customers are not limited to buying
electricity from the local PES and can choose to buy from a second tier
supplier. Such customers are typically larger commercial, agricultural and
industrial electricity users. Second tier suppliers compete with one another
and with the local PES to supply customers in this competitive (or "non-
franchise") sector of the market.
 
  Under the current licensing regime, from April 1, 1998 all customers,
including those who are currently Franchise Supply Customers, will be free to
choose their electricity supplier.
 
  The supply of electricity to Franchise Supply Customers is subject to price
control. The maximum average charge per unit supplied (in pence per kilowatt
hour) is controlled by a formula based upon P+RPI-Xs+Y (the "Supply Price
Control Formula") where Xs is currently 2%. As with the Distribution Price
Control Formula, P reflects the previous maximum average price per unit of
electricity supplied (in pence per kilowatt hour). RPI reflects the percentage
change in the Retail Price Index between the previous year and the current
year. The Xs factor is established by the Regulator following review. The Y
term is a pass through of certain costs which are either largely outside the
control of the REC or have been regulated elsewhere. It thus covers the REC's
electricity purchase costs, including both direct Pool purchase costs and
costs of hedging, transmission charges made by NGC, distribution charges made
by its own and other REC distribution businesses and the Fossil Fuel Levy
(described below) or amounts equivalent thereto in respect of the purchase of
non-leviable electricity which are attributable to Franchise Supply Customers.
As with the Distribution Price Control Formula, there is a correction factor
in the Supply Price Control Formula in the event of over or under charging.
 
                                      45
<PAGE>
 
  If a REC has overcharged in the previous year, the maximum average charge
per unit supplied is reduced by an amount to reflect the excess income
received, to which is added interest. In the event of undercharging, the
Supply Price Control Formula allows the licensee to recover the shortfall in
income plus interest.
 
  If, in any year, the average charge per unit supplied exceeds the permitted
maximum average charge per unit supplied by more than 4%, then, in the next
following year, the REC may not increase supply charges to Franchise Supply
Customers unless it has satisfied the Regulator that the average charge per
unit in that next following year is not likely to exceed the permitted maximum
average charge. If, in respect of any two successive years, the sum of the
amounts by which the average charge per unit supplied has exceeded the
permitted maximum average charge per unit supplied in the second of those
years is more than 5% of that permitted maximum average charge, then, in the
next following year, the REC may be required by the Regulator to adjust its
charges so that they fall within the maximum permitted average charge. If, in
respect of two successive years, the licensee undercharges by more than 10% of
the maximum average charge, the Regulator may, by directions to the licensee,
limit the amount by which such undercharging may be recovered.
 
  The initial value of Xs was set at 0 for all the RECs on March 31, 1990. The
Supply Price Control Formula was reviewed by the Regulator with effect from
April 1, 1994, when the Xs term was set at 2% for all the RECs. This will
apply to the period ending March 31, 1998. On this date, the exclusive right
of the RECs to supply Franchise Supply Customers is scheduled, under the
current licensing structure, to come to an end. However, the Regulator has
indicated that price regulation for supply to Franchise Supply Customers may
be extended for an interim period until an adequate level of competition is
established.
 
THE POOL
 
  The Pool was established at the time of privatization for bulk trading of
electricity in England and Wales between generators and suppliers. The Pool
reflects two principal characteristics of the physical generation and supply
of electricity from a particular generator to a particular supplier. First, it
is not possible to trace electricity from a particular generator to a
particular supplier. Second, it is not practicable to store electricity in
significant quantities, creating the need for a constant matching of supply
and demand. Subject to certain exceptions, all electricity generated in
England and Wales must be sold and purchased through the Pool. All licensed
generators and suppliers must become signatories to the Pooling and Settlement
Agreement, which governs the constitution and operation of the Pool and the
calculation of payments due to and from generators and suppliers. The Pool
also provides centralized settlement of accounts and clearing. The Pool does
not itself buy or sell electricity.
 
  Prices for electricity are set by the Pool daily for each half hour of the
following day based on the bids of the generators and a complex set of
calculations matching supply and demand and taking account of system
stability, security and other costs. A computerized system (the settlement
system) is used to calculate prices and to process metered, operational and
other data and to carry out the other procedures necessary to calculate the
payments due under the Pool trading arrangements. The settlement system is
administered on a day-to-day basis by NGC Settlements Limited, a subsidiary of
NGC, as settlement system administrator.
 
FOSSIL FUEL LEVY
   
  All the RECs are subject to an obligation to obtain a specified amount of
generating capacity from non-fossil fuel sources (the "NFFOs"). Because
electricity generated from non-fossil fuel plants is generally more expensive
than electricity from fossil fuel plants, a levy system (the "Fossil Fuel
Levy") has been instituted to reimburse the generators and the RECs for the
extra costs involved. The Regulator sets the amount of the Fossil Fuel Levy
annually. The current Fossil Fuel Levy is 10% of the value of sales of
electricity generated from fossil fuel sources. However, the Regulator
confirmed on July 16, 1996 a reduction to 3.7% for the period November 1, 1996
to March 31, 1997.

REGULATION UNDER THE ELECTRICITY ACT 1989
 
THE REGULATOR
 
  The principal legislation governing the structure and regulation of the
electricity industry in Great Britain is the Electricity Act. The Electricity
Act established the industry structure described above so as to enable
privatization to take place. The Electricity Act also created the
institutional framework under which the industry is currently regulated,
including the office of the Regulator, who is appointed by the Secretary of
State. The present Regulator, Professor Stephen Littlechild, was appointed for
a five year term commencing September 1, 1989 and has since been reappointed
for a further five year term.
 
  The Regulator's functions under the Electricity Act include granting
licenses to generate, transmit or supply electricity (a function which he
exercises under a general authority from the Secretary of State); proposing
modifications to licenses, and making license modification references to the
MMC; enforcing compliance with license conditions; advising the Secretary of
State in respect of the setting of each NFFO; calculating the Fossil Fuel Levy
rate and collecting the levy; determining certain disputes between electricity
licensees and customers; and setting standards of performance for electricity
licensees.
 
  The Regulator exercises concurrently with the Director General of Fair
Trading certain functions relating to monopoly situations under the Fair
Trading Act 1973 and certain functions relating to courses of conduct which
have, or are intended or likely to have, the effect of restricting, distorting
or preventing competition in the generation, transmission or supply of
electricity under the Competition Act 1980.
 
  The Electricity Act requires the Regulator and the Secretary of State to
exercise their functions in the manner each considers is best calculated: to
secure that all reasonable demands for electricity are satisfied; to secure
that license holders are able to finance their licensed activities; and to
promote competition in the generation and supply of electricity.
 
  Subject to these duties, the Secretary of State and the Regulator are
required to exercise their functions in the manner which each considers is
best calculated: to protect the interests of consumers of electricity supplied
by licensed suppliers in respect of price, continuity of supply, and the
quality of electricity supply services; to promote efficiency and economy on
the part of licensed electricity suppliers and the efficient use of
electricity supplied to consumers; to promote research and development by
persons authorized by license to generate, transmit or supply electricity; to
protect the public from the dangers arising from the generation, transmission
or supply of electricity; and to secure the establishment of machinery for
promoting the health and safety of workers in the electricity industry. The
Secretary of State and the Regulator also have a duty to take into account the
effect on the physical environment of activities connected with the
generation, transmission or supply of electricity.
 
  In performing their duties to protect the interests of consumers in respect
of prices and other terms of supply, the Secretary of State and the Regulator
have a duty to take into account in particular the interests of consumers in
rural areas. In performing their duties to protect the interests of consumers
in respect of the quality of electricity supply services, they have a duty to
take into account in particular the interests of those who are disabled or of
pensionable age.
 
LICENSES
 
 Generation Licenses
 
  Unless covered by an exemption, all electricity generators operating a power
station in Great Britain are required to have a generation license. There are
currently 41 generation license holders in Great Britain. The conditions
attached to a generation license in England and Wales require the holder,
among other things, to comply with a grid code, be a member of the Pool and
submit relevant generating sets for central dispatch. The conditions attached
to generation licenses in Scotland require the holder, among other things, to
comply with a
 
                                      47
<PAGE>
 
grid code. Failure to comply with any of the generation license conditions may
subject the licensee to a variety of sanctions, including enforcement orders
by the Regulator, or license revocation if an enforcement order is not
complied with.
 
 PES Licenses
 
  Each of the RECs, Scottish Power and Hydro-Electric has a PES license for
its franchise area and is required, under the Electricity Act, to supply
electricity upon request to any premises in that area, except in specified
circumstances. Each PES is also required not to discriminate between its own
supply business and other users of its distribution system. PESs are subject
to separate price controls on the amounts they may charge for the supply of
electricity to Franchise Supply Customers and in respect of distribution
charges. The PES licenses also require the licensee to procure electricity at
the best price reasonably obtainable having regard to the sources available.
   
  The Regulator published on August 15, 1996 further information relating to
the RECs' performance in relation to their distribution and supply price
controls. The publication entitled "Yardstick of Electricity Purchase Costs"
includes information about the generation costs which they pass through to
Franchise Supply Customers under the Supply Price Control Formula. The
Regulator also stated that it was his intention to review the supply price
controls applicable to PESs with a view to proposing possible new controls to
take effect on April 1, 1998 when the present franchise supply market will be
opened to competition. He issued a consultation paper on this matter on
September 5, 1996 entitled "The Competitive Electricity Market from 1998:
Price Restraints."     
 
  In England and Wales, each PES license limits the extent of the generation
capacity in which the relevant REC may hold an interest without the prior
consent of the Regulator ("own-generation limits"). These own-generation
limits, expressed in megawatts, currently restrict the participation of a REC
in generation to a level of approximately 15% of the total electricity
consumption in that REC's franchise area. In the case of SWEB, the own-
generation limit is fixed at 400 MW.
 
  The Regulator has stated that it would be reasonable to consider a REC's
request to increase its own-generation limit on condition that it accepted
explicit restrictions on the contracts it signed with its supply business, and
that at a minimum the REC would be prohibited from passing additional own-
generation contracts into its franchise supply market. He considers that an
increase in own-generation limits subject to such restrictions could allow a
REC to contribute more fully to the development of competition in generation
without the allegation that it was exploiting its captive market and local
monopoly position. In June 1996, the Regulator stated that he had indicated to
Eastern Group plc, in the context of its acquisition of 6,000 MW of generating
capacity from National Power and PowerGen, that he would be favorably inclined
to relax the own-generation limits subject to the Regulator and Eastern Group
plc agreeing to license modifications as set out in a consultation paper which
he had published in August 1995.
 
 Second Tier Supply Licenses
 
  Other than a PES in its franchise area and subject to certain other
exceptions, a supplier of electricity to premises in Great Britain must
possess a second tier supply license. Subject to the restrictions described in
"Electricity Supply" above, second tier licensees may compete for the supply
of electricity with one another and with the PES for the relevant area. There
are currently 39 second tier supply license holders for England and Wales and
24 for Scotland.
 
 Transmission Licenses
 
  In England and Wales, NGC is the only transmission license holder. The
transmission license imposes on NGC the obligation to operate the merit order
system for the central dispatch of generating sets and gives NGC
responsibility for the economic purchasing of ancillary services from
generators and suppliers. The transmission
 
                                      48
<PAGE>
 
license requires NGC to offer terms on a non-discriminatory basis for the
carrying out of works for connection to, and use of, the transmission system
and for use of the interconnections.
 
 Modifications to Licenses
 
  Subject to a power of veto by the Secretary of State, the Regulator may
modify license conditions with the agreement of the license holder. He must
first publish the proposed modifications and consider representations or
objections made. Following the acquisition of SWEB by the Company, SWEB's PES
license was modified, by agreement, to take into account the fact that the PES
license was now held by a subsidiary company. In particular, the license was
modified to provide that, with few exceptions, the only business activities
which SWEB is permitted to undertake directly are its franchise and second
tier supply businesses and its distribution business. The license now also
requires SWEB to ensure that it has sufficient management and financial
resources and facilities to conduct its supply and distribution businesses and
to comply with its statutory and license obligations. The directors of SWEB
are required to give annual certificates to the Regulator to that effect.
Further, the consent of the Regulator is required for SWEB to create security
over its assets, to incur indebtedness or to give guarantees, unless the
transaction is on normal commercial and arm's length terms and for a
"permitted purpose" (which refers to the supply, distribution or generation
business, or any business conducted by SWEB or its affiliates or related
undertakings (subsidiaries) prior to the take-over). The consent of the
Regulator is also required before SWEB may transfer assets or make loans to
affiliates or related undertakings (subsidiaries). However, various matters,
such as payment of dividends out of distributable reserves, repayments of
capital, and payments on normal commercial and arm's length terms for goods,
services or assets supplied, do not require the consent of the Regulator.
These provisions are subject to an overriding provision in the PES license
which prevents any REC from disposing of (which would include creating a
security interest in) distribution assets.
 
  If the Regulator fails to agree modifications with a license holder, he may
refer a matter relating to generation, transmission or supply of electricity
under a license to the MMC. If the MMC finds that the matter referred to it
has, or may be expected to have, specified effects adverse to the public
interest which could be remedied or prevented by a license modification, the
Regulator is required to make modifications that appear to him requisite for
the purpose of remedying or preventing the adverse effects identified by the
MMC. Modifications to license conditions may also be made by the Secretary of
State as a consequence of monopoly, merger or other competition references
under general UK competition law.
 
 Term and Revocation of Licenses
 
  SWEB's PES license shall continue until at least 2025 unless revoked. Under
ordinary circumstances, the license may not be revoked except on 25 year's
prior notice, which notice may not be given until 2000. Otherwise, the
Secretary of State may revoke a PES license by not less than 30 days' notice
in writing to the licensee in certain specified circumstances including any
failure to comply with a final order of the Regulator requiring the license
holder to comply with its license conditions or requirements.

                        DESCRIPTION OF THE SENIOR NOTES
   
  The Senior Notes are to be issued under and governed by an Indenture, as
supplemented by a First Supplemental Indenture, to be dated as of    , 1996
(collectively the "Indenture"), among the Company, Bankers Trust Company, as
trustee (the "Trustee") and Bankers Trust Luxembourg S.A. as paying and
transfer agent (the "Paying Agent"), a copy of which is filed as an exhibit to
the Registration Statement. The following summaries of certain provisions of
the Indenture do not purport to be complete and are subject to, and are
qualified in their entirety by reference to, all the provisions of the
Indenture. Copies of the Indenture are available for inspection on a Business
Day during normal business hours at the principal office of the Company, at
the office of the Trustee in the City of New York and at the office of the
Paying Agent in Luxembourg. The Holders are entitled to the benefits of, are
bound by, and are deemed to have notice of, all the provisions of the
Indenture. Wherever particular sections or defined terms of the Indenture are
referred to, such sections or defined terms are incorporated herein by
reference.     
 
GENERAL
 
  The Indenture does not limit the aggregate principal amount of the debt
securities that may be issued thereunder and provides that debt securities may
be issued from time to time in one or more series. The Senior Notes will
mature on     , 2006 and will be limited to US$235,000,000 in aggregate
principal amount. Each Senior Note will bear interest at the rate per annum
shown on the cover page of this Prospectus from    , 1996 or from the most
recent interest payment date to which interest has been paid or provided for.
Interest on the Senior Notes will be payable semiannually on     and
of each year, commencing on      , 1996 until the principal amount has been
paid or made available for payment. Interest on the Senior Notes will be
computed on the basis of a 360-day year of twelve 30-day months.
 
  The principal of and interest on the Senior Notes will be payable in U.S.
dollars or in such other coin or currency of the United States of America as
at the time of payment is legal tender for the payment of public and private
debts.
 
  Application has been made to list the Senior Notes on the Luxembourg Stock
Exchange.
   
  The Senior Notes will be direct, unsecured and unsubordinated obligations of
the Company ranking pari passu with all other unsecured and unsubordinated
obligations of the Company (except those obligations preferred by operation of
law). The Senior Notes will effectively rank junior to any secured
indebtedness of the Company to the extent of the assets securing such
indebtedness and to any indebtedness of the Company's subsidiaries to the
extent of the assets of such subsidiaries. Substantially all of the Company's
consolidated assets other than the stock of SWEB are currently held by the
Company's subsidiaries. The Indenture contains no restrictions on the amount
of additional indebtedness which may be incurred by the Company or its
subsidiaries; however, the Indenture contains certain restrictions on the
ability of the Company and its Significant Subsidiaries to incur secured
indebtedness. See "--Covenants--Limitation on Liens." The ability of the
Company to pay principal and interest on the Senior Notes is, to a large
extent, dependent upon the payment to it of distributions, dividends, interest
or other amounts by SWEB. While the Company does not intend to pay principal
of the Senior Notes out of such amounts, but rather intends to refinance such
principal, its ability to do so will also be, to a large extent, dependent
upon the payment to it of such amounts by SWEB. SWEB can make distributions of
dividends to the Company under English law to the extent that it has
distributable reserves, subject to the retention of sufficient financial
resources to conduct its supply and distribution businesses as required by its
PES license.     
 
DESCRIPTION OF THE BOOK-ENTRY SYSTEM
 
GENERAL
 
  The Senior Notes will be issued only as a Global Note in bearer form and
will be payable only in US dollars. Title to such Global Note will pass by
delivery. The Global Note will be deposited on issue with Bankers Trust
Company, as book-entry depositary (the "Book-Entry Depositary"), which will
hold the Global Note for the benefit of DTC and its Participants pursuant to
the terms of the deposit agreement (the "Deposit Agreement") dated as of
   ,1996 among the Company, the Book-Entry Depositary and the holders and
beneficial owners from time to time of interests in the Book-Entry Interest
(as defined below). Pursuant to the Deposit Agreement
 
                                      53
<PAGE>
 
   
and a letter of representations from the Company and the Trustee to DTC (the
"Letter of Representations"), the Book-Entry Depositary will issue one or more
certificateless depositary interests (the "Book-Entry Interest"), which
together will represent a 100% interest in the underlying Global Note. Such
Book-Entry Interest will be issued to DTC, which will operate a book-entry
system for interests in the Book-Entry Interest. Unless and until the Global
Note is exchanged in whole for Definitive Registered Notes (as defined below),
the Book-Entry Interest held by DTC may not be transferred except as a whole
by DTC to a nominee of DTC or by a nominee of DTC to DTC or another nominee of
DTC or by DTC or any such nominee to a successor of DTC or a nominee of such
successor.     
 
  Ownership of interests in the Book-Entry Interest will be limited to
persons, including depositaries for Euroclear and Cedel Bank, that have
accounts with DTC ("Participants") or persons that hold interests through
Participants ("Indirect Participants"). Upon the issuance by the Book-Entry
Depositary of the Book-Entry Interest to DTC, DTC will credit, on its book-
entry registration and transfer system, the Participants' accounts with the
respective interests owned by such Participants. Ownership of interests in the
Book-Entry Interest will be shown on, and the transfer of such interests in
the Book-Entry Interest will be effected only through, records maintained by
DTC (with respect to interests of Participants) and on the records of
Participants (with respect to interests of Indirect Participants). The laws of
some states may require that certain purchasers of securities take physical
delivery of such securities in definitive form. Such limits and such laws may
impair the ability of such purchasers to own, transfer or pledge interests in
the Book-Entry Interest.
 
  So long as the Book-Entry Depositary, or its nominee, is the Holder of the
Global Note, the Book-Entry Depositary or such nominee, as the case may be,
will be considered the sole Holder of such Global Note (and the Senior Notes)
for all purposes under the Indenture. Except as set forth below under "--
Definitive Senior Notes," Participants or Indirect Participants will not be
entitled to have Senior Notes registered in their names, will not receive or
be entitled to receive physical delivery of Senior Notes in definitive bearer
or registered form and will not be considered the owners or Holders thereof
under the Indenture or the Deposit Agreement. Accordingly, each person owning
an interest in the Book-Entry Interest must rely on the procedures of the
Book-Entry Depositary and DTC and, if such person is not a Participant in DTC,
on the procedures of the Participant through which such person owns its
interest, to exercise any rights and obligations of a Holder under the
Indenture or the Deposit Agreement. See "--Action by Holders of Senior Notes."
 
 
  In addition to a Paying Agent in the Borough of Manhattan, The City of New
York, the Company will, so long as the Senior Notes are listed on the
Luxembourg Stock Exchange and the rules of such Exchange so require, maintain
a Paying Agent in Luxembourg.
 
INFORMATION REGARDING DTC, EUROCLEAR AND CEDEL BANK
 
  DTC
 
  DTC has advised the Company as follows: DTC is a limited-purpose trust
company organized under the New York Banking Law, a "banking organization"
within the meaning of the New York Banking Law, a member of the Federal
Reserve System, a "clearing corporation" within the meaning of the New York
Uniform Commercial Code, and a "clearing agency" registered pursuant to the
provisions of Section 17A of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"). DTC holds securities that its Participants deposit with
DTC. DTC also facilitates the settlement among Participants of securities
transactions, such as transfers and pledges, in deposited securities through
electronic computerized book-entry changes in Participants' accounts, thereby
eliminating the need for physical movement of securities certificates.
Participants include securities brokers and dealers, banks, trust companies,
clearing corporations and certain other organizations. DTC is owned by a
number of its Participants and by the New York Stock Exchange Inc. and the
American Stock Exchange Inc. and the National Association of Securities
Dealers, Inc. Access to the DTC system is also available to others such as
securities brokers and dealers, banks and trust companies that clear through
or maintain a custodial relationship with a Participant, either directly or
indirectly. The rules applicable to DTC and its Participants are on file with
the Securities and Exchange Commission (the "Commission").
 
                                      54
<PAGE>
 
  Euroclear and Cedel Bank
 
  Euroclear and Cedel Bank each hold securities for their account holders and
facilitate the clearance and settlement of securities transactions by
electronic book-entry transfer between their respective account holders,
thereby eliminating the need for physical movements of certificates and any
risk from lack of simultaneous transfers of securities.
 
  Euroclear and Cedel Bank provide various services including safekeeping,
administration, clearance and settlement of internationally traded securities
and securities lending and borrowing. Euroclear and Cedel Bank also deal with
domestic securities markets in several countries through established
depositary and custodial relationships. Euroclear and Cedel Bank have
established an electronic bridge between their two systems across which their
respective account holders may settle trades with each other.
 
  Account holders in Euroclear and Cedel Bank are world-wide financial
institutions, including underwriters, securities brokers and dealers, banks,
trust companies and clearing corporations. Indirect access to Euroclear and
Cedel Bank is available to other institutions that clear through or maintain a
custodial relationship with an account holder of either system.
 
  Account holders' overall contractual relations with Euroclear and Cedel Bank
are governed by the respective rules and operating procedures of Euroclear and
Cedel Bank and any applicable laws. Euroclear and Cedel Bank act under such
rules and operating procedures only on behalf of their respective account
holders and have no record of or relationship with persons holding through
their respective account holders.
 
  The Company understands that under existing industry practices, if either
the Company or the Trustee requests any action of owners of interests in the
Book-Entry Interest or if an owner of an interest in the Book-Entry Interest
desires to give or take any action that a Holder is entitled to give or take
under the Indenture, DTC would authorize the Participants owning the interests
in the Book-Entry Interest to give or take such action, and such Participants
would authorize Indirect Participants to give or take such action or would
otherwise act upon the instructions of such Indirect Participants.
 
PAYMENTS ON THE SENIOR NOTES
 
  Payments of any amounts in respect of the Global Note will be made through a
Paying Agent to the Book-Entry Depositary, as the Holder thereof. The Book-
Entry Depositary will pay an amount equal to each such payment to DTC, which
will distribute such payments to its Participants.
 
  DTC, upon receipt of any such payment from the Book-Entry Depositary, will
immediately credit Participants' accounts with payments in amounts
proportionate to their respective ownership of interests in the Book-Entry
Interest as shown on the records of DTC. The Company expects that payments by
Participants to owners of interests in the Book-Entry Interest held through
such Participants will be governed by standing customer instructions and
customary practices and will be the responsibility of such Participants.
   
  Neither the Company nor any agent of the Company will have any
responsibility or liability for any aspect relating to payments made or to be
made by the Book-Entry Depositary to DTC in respect of the Senior Notes or the
Book-Entry Interest. None of the Company, the Trustee, the Book-Entry
Depositary or any agent of any of the foregoing will have any responsibility
or liability for any aspect relating to payments made or to be made by DTC on
account of a Participant's or Indirect Participant's ownership of an interest
in the Book-Entry Interest or for maintaining, supervising or reviewing any
records relating to a Participant's or Indirect Participant's interests in the
Book-Entry Interest.     
 
  If any Definitive Registered Note has been issued, the interest payable on
such Definitive Registered Note other than at maturity will be paid to the
holder in whose name such Definitive Registered Note is registered at the
close of business on the    or     (whether or not a Business Day), as the
case may be, immediately preceding the due date for such payment (each a
"Record Date"). The principal of a Definitive Registered Note
 
                                      55
<PAGE>
 
will be payable to the person in whose name such Definitive Registered Note is
registered at the close of business on the immediately preceding Record Date
upon surrendering such Definitive Registered Note. Interest payable at
maturity will be payable to the person to whom principal is payable.
 
  If any Definitive Registered Notes have been issued, payments of interest on
such Definitive Registered Notes to be paid other than at maturity will be
made by check to the person entitled thereto at such person's address
appearing on the Security Register. Payments of any interest on the Definitive
Registered Notes may also be made, in the case of a Holder of at least
US$1,000,000 aggregate principal amount of Senior Notes, by wire transfer to a
US Dollar account maintained by the payee with a bank in the United States;
provided that such Holder elects payment by wire transfer by giving written
notice to the Trustee or a Paying Agent to such effect designating such
account no later than 15 days immediately preceding the relevant due date for
payment (or such other date as the Trustee may accept in its discretion).
 
  Any monies paid by the Company to the Trustee or any Paying Agent, or held
by the Company in trust, for the payment of the principal of or any interest
or Additional Amounts on any Senior Notes and remaining unclaimed at the end
of two years after such principal, interest or Additional Amounts become due
and payable will be repaid to the Company, or released from the trust, upon
its written request, and upon such repayment or release all liability of the
Company, the Trustee and such Paying Agent with respect thereto will cease.
 
  If the due date for payment of principal or any interest installment or any
Additional Amount in respect of any Senior Note is not a Business Day, the
Holder thereof will not be entitled to payment of the amount due until the
next succeeding Business Day and will not be entitled to any further interest
or other payment in respect of any such delay.
   
   All payments to the Book-Entry Depositary in respect of the Global Note,
and all payments to the Holders of the Definitive Registered Notes, if issued,
will be made without deduction or withholding for any UK taxes or other
governmental charges, or if any such deduction or withholding is required to
be made under the provisions of any applicable UK law or regulation, except as
described under "--Additional Amounts," such Additional Amounts will be paid
as may be necessary in order that the net amounts received by any Holder of
the Global Note or of any Definitive Registered Note, after such deduction or
withholding, will equal the amounts that such Holder would have otherwise
received in respect of the Global Note or of such Definitive Registered Note
absent such deduction or withholding.     
 
REDEMPTION
   
  In the event the Global Note (or a portion thereof) is redeemed, the Book-
Entry Depositary will deliver all amounts received by it in respect of the
redemption of the Global Note to DTC and (in the case of redemption in full)
surrender the Global Note to the Trustee for cancellation. The redemption
price payable in connection with the redemption of interests in the Book-Entry
Interest will be equal to the amount received by the Book-Entry Depositary in
connection with the redemption of the Global Note (or a portion thereof). For
any redemptions of the Global Note in part, selection of interests in the
Book-Entry Interest to be redeemed will be made by DTC on a pro rata basis (or
on such other basis as DTC deems fair and appropriate); provided that no
interest in the Book-Entry Interest of $1,000 principal amount or less shall
be redeemed in part. Once redeemed in part, a new Global Note in the principal
amount equal to the unredeemed portion thereof will be issued and delivered to
the Book-Entry Depositary.     
 
TRANSFERS
 
  All transfers of interests in the Book-Entry Interest will be recorded in
accordance with the book-entry system maintained by DTC, pursuant to customary
procedures established by DTC and its Participants. See "--General."

ACTION BY HOLDERS OF SENIOR NOTES
 
  The Company understands that under existing industry practices, if it
requests any action of Holders of Senior Notes or if an owner of an interest
in the Book-Entry Interest desires to give or take any action that a Holder is
entitled to give or take under the Indenture or the owner of an interest in
the Book-Entry Interest is entitled to give or take under the Deposit
Agreement, DTC would authorize the Participants owning the relevant interest
in the Book-Entry Interest to give or take such action, and such Participants
would authorize Indirect Participants to give or take such action or would
otherwise act upon the instructions of owners of interests in the Book-Entry
Interest holding through them.
 
  As soon as practicable after receipt by the Book-Entry Depositary of notice
of any solicitation of consents or request for a waiver or other action by the
Holders of Senior Notes, the Book-Entry Depositary will mail to DTC a notice
containing (a) such information as is contained in such notice, (b) a
statement that at the close of business on a specified record date DTC will be
entitled to instruct the Book-Entry Depositary as to the consent, waiver or
other action, if any, pertaining to the Senior Notes and (c) a statement as to
the manner in which such instructions may be given. Upon the written request
of DTC, the Book-Entry Depositary shall endeavor insofar as practicable to
take such action regarding the requested consent, waiver or other action in
respect of the Senior Notes in accordance with any instructions set forth in
such request. DTC is expected to follow the procedures described above with
respect to soliciting instructions from its Participants. The Book-Entry
Depositary will not exercise any discretion in the granting of consents or
waivers or the taking of any other action relating to the Deposit Agreement,
the DTC Agreement or the Indenture.
 
REPORTS AND NOTICES
   
  So long as the Senior Notes are listed on the Luxembourg Stock Exchange and
the rules of the Luxembourg Stock Exchange so require, notices to Holders of
the Senior Notes will, in addition to being sent to the Book-Entry Depositary,
also be published in a leading newspaper having general circulation in
Luxembourg (which is expected to be the Luxemburger Wort). The Book-Entry
Depositary will immediately send to DTC a copy of any notices, reports and
other communications received by it relating to the Company or the Senior
Notes. In the case of Definitive Registered Notes, all notices regarding the
Senior Notes will, in addition to publication as referred to above (if
applicable), be mailed to Holders by first-class mail at their respective
addresses as they appear on the registration books of the Registrar.     
 
ACTION BY BOOK-ENTRY DEPOSITARY
   
  Upon the occurrence of an Event of Default with respect to the Senior Notes
or in connection with any other right of the Holder of the Global Note under
the Indenture, if requested in writing by DTC, the Book-Entry Depositary will
take such action as shall be requested in such notice, provided that the Book-
Entry Depositary has been offered indemnity satisfactory to it against the
costs, expenses and liabilities that might be incurred by it in compliance
with such request by DTC.     
 
AMENDMENT AND TERMINATION
   
  The Deposit Agreement may be amended by agreement between the Company and
the Book-Entry Depositary, and the consent of DTC shall not be required in
connection with any amendment to the Deposit Agreement (i) to cure any formal
defect, omission, inconsistency or ambiguity in such Deposit Agreement, (ii)
to add to the covenants and agreements of the Company or the Book-Entry
Depositary, (iii) to effect the assignment of the Book-Entry Depositary's
rights and duties to a qualified successor, (iv) to comply with the US
Securities Act of 1933, as amended (the "Securities Act"), the Exchange Act or
the US Investment Company Act of 1940, as amended, or any other applicable
securities laws, (v) to modify the Deposit Agreement in connection with an
amendment to the Indenture that does not require the consent of the Holders of
Senior Notes or (vi) to modify, alter, amend or supplement the Deposit
Agreement in any other respect not inconsistent with such agreement which, in
the opinion of counsel acceptable to the Company, is not materially adverse to
DTC or the beneficial owners of the interests in the Book-Entry Interest. No
amendment which materially adversely     
 
                                      57
<PAGE>
 
affects any holder or beneficial owner of an interest in the Book-Entry
Interest may be made to the Deposit Agreement without the consent of such
holder or beneficial owner.
 
  If Definitive Registered Notes are issued by the Company in exchange for the
entire Global Note, the Book-Entry Depositary, as Holder of the Global Note,
will surrender the Global Note against receipt of the Definitive Registered
Notes and distribute the Definitive Registered Notes to the persons and in the
amounts as specified by DTC, whereupon the Deposit Agreement will terminate
with respect to the Senior Notes. The Deposit Agreement may also be terminated
upon the resignation of the Book-Entry Depositary if no successor has been
appointed within 120 days as set forth under "--Resignation of Book-Entry
Depositary" below. Any Definitive Registered Notes will be issued, if at all,
in accordance with the provisions described under "--Definitive Senior Notes"
below.
 
RESIGNATION OF BOOK-ENTRY DEPOSITARY
 
  The Book-Entry Depositary may at any time resign as Book-Entry Depositary.
If a successor depositary meeting the requirements specified in the Deposit
Agreement has agreed to enter into arrangements with the same effect as the
Deposit Agreement, the Book-Entry Depositary shall deliver the Global Note to
that successor. If no such successor has so agreed within 120 days, the terms
of the Deposit Agreement will oblige the Book-Entry Depositary to request the
Company to issue Definitive Registered Notes. On receipt of such Definitive
Registered Notes, the Book-Entry Depositary will surrender the Global Note and
distribute such Definitive Registered Notes in accordance with the directions
of DTC. The Deposit Agreement will then terminate with respect to the Senior
Notes.
 
OBLIGATION OF BOOK-ENTRY DEPOSITARY
 
  The Book-Entry Depositary will assume no obligation or liability under the
Deposit Agreement or the DTC Agreement other than to act in good faith without
negligence or wilful misconduct in the performance of its duties thereunder.
 
SETTLEMENT
 
  Initial settlement for the Senior Notes and settlement of any secondary
market trades in the Senior Notes will be made in same-day funds. Interests in
the Book-Entry Interest will settle in DTC's Same-Day Funds Settlement System.
 
DEFINITIVE SENIOR NOTES
   
  Owners of interests in the Book-Entry Interest will be entitled to receive,
through DTC, definitive Senior Notes in registered form ("Definitive
Registered Notes") in respect of such interest only if an Event of Default has
occurred and is continuing with respect to the Senior Notes and the Holder, in
such circumstance, upon instructions from owners of interests representing a
majority in outstanding principal amount in the Book-Entry Interest shall have
requested in writing that the Global Note be exchanged for one or more
Definitive Registered Notes. If owners of interests in the Book-Entry Interest
make a request pursuant to the preceding sentence, all of the owners of
interests in the Book-Entry Interest will receive Definitive Registered Notes
in respect of their interests. In addition, Definitive Registered Notes shall
be issued if at any time (a) DTC notifies the Company and the Book-Entry
Depositary that it is unwilling to or unable to continue to hold the Book-
Entry Interest or if at any time it ceases to be a "clearing agency"
registered under the Exchange Act and, in either case, a successor is not
appointed by the Company within 120 days (b) the Book-Entry Depositary
notifies the Company that it is unwilling or unable to continue as Book-Entry
Depositary with respect to the Global Note and no successor is appointed by
the Company within 120 days or (c) the Company in its sole discretion
determines that Definitive Registered Notes shall be issued and executes and
delivers to the Trustee an Officer's Certificate providing that the Global
Note shall be so exchanged. Definitive Registered Notes so issued will be
issued in denominations of $1,000 or integral multiples thereof and will be
issued in registered form only, without coupons. Such Definitive Registered
Notes shall be registered in the name or names of such person or person as the
Book-Entry Depositary shall notify the Trustee based on the instructions of
DTC. It is expected that such instructions may be based upon directions
received by DTC from its Participants with respect to ownership of beneficial
interests in the Book-Entry Interest.     
 
 
                                      58
<PAGE>
 
   
  PARTICIPANTS AND INDIRECT PARTICIPANTS SHOULD BE AWARE THAT, UNDER CURRENT
UK TAX LAW, UPON THE ISSUANCE TO SUCH PARTICIPANTS AND INDIRECT PARTICIPANTS
OF DEFINITIVE REGISTERED NOTES, SUCH PARTICIPANTS AND INDIRECT PARTICIPANTS,
AS HOLDERS OF DEFINITIVE REGISTERED NOTES, WILL BECOME SUBJECT TO UK INCOME
TAX (CURRENTLY AT THE RATE OF 20%) TO BE WITHHELD ON ANY PAYMENTS OF INTEREST
ON THE SENIOR NOTES AS SET FORTH UNDER "CERTAIN INCOME TAX CONSIDERATIONS--UK
INCOME TAX CONSIDERATIONS." IF SUCH DEFINITIVE REGISTERED NOTES ARE ISSUED
PURSUANT TO THE REQUEST OF A PARTICIPANT OR INDIRECT PARTICIPANT FOLLOWING AN
EVENT OF DEFAULT, THE COMPANY WILL NOT BE OBLIGATED TO PAY ANY ADDITIONAL
AMOUNTS TO PARTICIPANTS AND INDIRECT PARTICIPANTS (AND THEIR TRANSFEREES) THAT
REQUEST OR GIVE INSTRUCTIONS THAT DEFINITIVE REGISTERED NOTES BE ISSUED.     
 
TRANSFER AND EXCHANGE OF DEFINITIVE SENIOR NOTES
 
  In the event that Definitive Registered Notes are in issue, a Holder may
transfer or exchange the Definitive Registered Notes in accordance with the
Indenture. The Registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents, and the
Company may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Company is not required to transfer or
exchange any Senior Notes selected for redemption or for a period of 15 days
before a selection of Senior Notes to be redeemed. Upon the issuance of
Definitive Registered Notes, Holders will be able to transfer and exchange
Definitive Registered Notes at the offices of the Paying and Transfer Agents;
provided that all transfers and exchanges must be effected in accordance with
the terms of the Indenture and, among other things, be recorded in the
Register maintained by the Registrar.
 
COVENANTS
 
  Except as otherwise set forth under "--Defeasance," below, for so long as
any Senior Notes remain outstanding or any amount remains unpaid on any of the
Senior Notes, the Company will comply with the terms of the covenants set
forth below.
 
PAYMENT OF PRINCIPAL AND INTEREST
 
  The Company will duly and punctually pay the principal of and interest and
Additional Amounts, if any, on the Senior Notes in accordance with the terms
of the Senior Notes and the Indenture.
 
MAINTENANCE OF OFFICE OR AGENCY
 
  The Company will maintain (i) in the Borough of Manhattan, The City of New
York, an office or agency of a Paying Agent where the Senior Notes may be paid
and notices and demands to or upon the Company in respect of the Senior Notes
and the Indenture may be served and, if Definitive Registered Notes have been
issued, an office or agency of a Transfer Agent where Senior Notes may be
surrendered for registration of transfer and exchange, and (ii) an office or
agency of a Paying Agent where the Senior Notes may be paid in Luxembourg so
long as the Senior Notes are listed on the Luxembourg Stock Exchange and the
rules of such Exchange so require. The Company will give prompt written notice
to the Trustee of the location, and any change in the location, of any such
office or agency. If at any time the Company shall fail to maintain any
required office or agency or shall fail to furnish the Trustee with the
address thereof, all presentations, surrenders, notices and demands may be
served at the office of the Trustee.
 
FURTHER ASSURANCES
   
  The Company and the Trustee will execute and deliver all such documents,
instruments and agreements and do all such other acts and things as may be
reasonably required to enable the Trustee to exercise and enforce its rights
under the Indenture and under the documents, instruments and agreements
required under the Indenture and to carry out the intent of the Indenture.
    
                                      59
<PAGE>
 
COMPLIANCE CERTIFICATES
 
  The Company will deliver to the Trustee within 120 days after the end of each
fiscal year of the Company a certificate from the principal executive,
financial or accounting officer of the Company, stating that in the course of
the performance by each signer of his duties as an officer of the Company he
would normally have knowledge of any default by the Company in the performance
and observance of any of the covenants contained in the Indenture, stating
whether or not he has knowledge of any such default without regard to any
period of grace or requirement of notice and, if so, specifying each such
default of which such signer has knowledge and the nature thereof.
 
CONSOLIDATION, MERGER, CONVEYANCE, SALE OR LEASE
 
  Nothing contained in the Indenture shall prevent the Company from
consolidating with or merging into another corporation or conveying,
transferring or leasing its properties and assets substantially as an entirety
to any person, provided that (a) the successor entity assumes the Company's
applicable obligations on the Senior Notes and (b) immediately after giving
effect to such transaction no Event of Default, and no event which, after
notice or lapse of time or both, would become an Event of Default, shall have
happened and be continuing.
 
LIMITATION ON LIENS
 
  Nothing contained in the Indenture in any way restricts or prevents the
Company or any subsidiary of the Company from incurring any indebtedness;
provided that neither the Company nor any Significant Subsidiary (as defined
below) shall issue, assume or guarantee any notes, bonds, debentures or other
similar evidences of indebtedness, in each case for money borrowed ("Debt"),
secured by a mortgage, lien, pledge, security interest or other encumbrance
("Lien") upon any property or assets (other than cash) without effectively
providing that the outstanding Senior Notes (together with, if the Company so
determines, any other indebtedness or obligation then existing or thereafter
created ranking equally with the Senior Notes) shall be secured equally and
ratably with (or prior to) such Debt so long as such Debt shall be so secured;
provided, however, that the term Lien shall not mean any easements, rights-of-
way, restrictions and other similar encumbrances and encumbrances consisting of
zoning restrictions, leases, subleases, licenses, sublicenses, restrictions on
the use of property or defects in the title thereto. The foregoing restriction
or Liens will not, however, apply to:
 
    (a) Liens in existence on the date of original issue of the Senior Notes;
 
    (b) (i) any Lien created or arising over any property which is acquired,
  constructed or created by the Company or any of its Significant
  Subsidiaries, but only if (A) such Lien secures only principal amounts (not
  exceeding the cost of such acquisition, construction or creation) raised
  for the purposes of such acquisition, construction or creation, together
  with any costs, expenses, interest and fees incurred in relation thereto or
  a guarantee given in respect thereof, (B) such Lien is created or arises on
  or before 90 days after the completion of such acquisition, construction or
  creation and (C) such Lien is confined solely to the property so acquired,
  constructed or created; or (ii) any Lien to secure indebtedness for
  borrowed money incurred in connection with a specifically identifiable
  project where the Lien relates to a property (including, without
  limitation, shares or other rights of ownership in the entity(ies) which
  own such property or project) involved in such project and acquired by the
  Company or a Significant Subsidiary after the date of original issue of the
  Senior Notes and the recourse of the creditors in respect of such
  indebtedness is limited to any or all of such project and property
  (including as aforesaid);

  proceedings, or any Lien in favor of a plaintiff or defendant in any action
  before a court or tribunal as security for costs

    (i) any extension, renewal or replacement (or successive extensions,
  renewals or replacements), as a whole or in part, of any Liens referred to
  in the foregoing clauses, for amounts not exceeding the principal amount of
  the Debt secured by the Lien so extended, renewed or replaced, provided
  that such extension, renewal or replacement Lien is limited to all or a
  part of the same property or assets that were covered by the Lien extended,
  renewed or replaced (plus improvements on such property).     
 
    Notwithstanding the foregoing, the Company and/or a Significant
  Subsidiary may create or permit to subsist Liens over any property, shares
  and/or stock so long as the aggregate amount of Debt secured by all such
  Liens (excluding therefrom the amount of Debt secured by Liens set forth in
  clauses (a) through (i), inclusive, above) does not exceed 10% of the
  consolidated net tangible assets of the Company and its subsidiaries on a
  consolidated basis.
     
    "Significant Subsidiary" means, at any particular time, any subsidiary of
  the Company whose gross assets or gross revenues (having regard to the
  Company's direct and/or indirect beneficial interest in the shares, or the
  like, of that subsidiary) represent at least 25% of the consolidated gross
  assets or, as the case may be, consolidated gross revenues of the Company.
         
    Consolidated net tangible assets is defined in the Indenture as the total
  of all assets (including revaluations thereof as a result of commercial
  appraisals, price level restatement or otherwise) appearing on a
  consolidated balance sheet of the Company, net of applicable reserves and
  deductions, but excluding goodwill, trade names, trademarks, patents,
  unamortized debt discount and all other like intangible assets (which term
  shall not be construed to include such revaluations), less the aggregate of
  the consolidated current liabilities of the Company appearing on such
  balance sheet.     
 
LIMITATION ON SALE AND LEASE-BACK TRANSACTIONS
 
  The Indenture provides that, so long as any of the Senior Notes remain
outstanding, neither the Company nor any Significant Subsidiary shall enter
into any arrangement with any person providing for the leasing by the Company
or a Significant Subsidiary of any assets which have been or are to be sold or
transferred by the Company or such Significant Subsidiary to such person (a
"Sale and Lease-Back Transaction") unless: (i) such transaction involves a
lease for a temporary period not to exceed three years; (ii) such transaction
is between the Company or a Significant Subsidiary and an affiliate of the
Company; (iii) the Company would be entitled to incur indebtedness secured by
a Lien on the assets or property involved in such transaction at least equal
in amount to the attributable debt with respect to such Sale and Lease-Back
Transaction, without equally and ratably securing the Senior Notes, pursuant
to "--Limitation on Liens" above, other than pursuant to the penultimate
paragraph thereof; (iv) such transaction is entered into within 60 days after
the initial acquisition by the Company of the assets or property subject to
such transaction; (v) after giving effect thereto, the aggregate amount of all
attributable debt with respect to all such Sale and Lease-Back Transactions
does not exceed 10% of consolidated net tangible assets of the Company and its
subsidiaries on a consolidated basis; or (vi) the Company or a Significant
Subsidiary within the 12 months preceding the sale or transfer or the 12
months following the sale or transfer, regardless of whether such sale or
transfer may have been made by the Company or such Significant Subsidiary, as
the case may be, applies, in the case of a sale or transfer for cash, an
amount equal to the net proceeds thereof and, in the case of a sale or
transfer otherwise than for cash, an amount equal to the fair value of the
assets so leased at the time of entering into such arrangement (as determined
by the Board of Directors of the Company or such Significant Subsidiary, as
the case may be), (a) to the retirement of indebtedness for money borrowed,
incurred or assumed by the Company or a Significant Subsidiary, as the case
may be, which by its terms matures at, or is extendible or renewable at the
option of the obligor to, a date more than 12 months after the date of
incurring, assuming or guaranteeing such debt or (b) to investment in any
assets of the Company or a Significant Subsidiary, as the case may be.

MODIFICATION OF THE INDENTURE
 
  The Indenture contains provisions permitting the Company and the Trustee,
with the consent of the Holders of a majority in aggregate in principal amount
of the outstanding Senior Notes, to modify the Indenture or any supplemental
indenture or the rights of the Holders of the Senior Notes; provided that no
such modification shall without the consent of each Holder of Senior Notes (a)
change the stated maturity upon which the principal of or the interest on the
Senior Notes is due and payable, (b) reduce the principal amount thereof or
the rate of interest thereon, (c) change any obligation of the Company to pay
Additional Amounts, (d) change any place of payment or the currency in which
the Senior Notes or the interest thereon is payable, (e) impair the right to
institute suit for the enforcement of any such payment on or after the stated
maturity thereof (or, in the case of redemption, on or after the redemption
date), (f) reduce the percentage in principal amount of the outstanding Senior
Notes, the consent of whose Holders is required for any waiver of compliance
with certain provisions of the Indenture or certain defaults thereunder and
their consequences provided for in the Indenture, (g) reduce the requirements
contained in the Indenture for quorum or voting or (h) modify certain
provisions of the Indenture. The Indenture provides that Senior Notes owned by
the Company or any of its Affiliates shall be deemed not to be outstanding
for, among other purposes, consenting to any such modification.
 
  The Indenture also contains provisions permitting the Company and the
Trustee to amend the Indenture in certain circumstances without the consent of
the Holders of any Senior Notes to cure any ambiguity, to correct or
supplement any provision therein which may be defective or inconsistent with
any other provision therein, to evidence the merger of the Company or the
replacement of the Trustee and to make any other changes that do not
materially adversely affect the rights of any Holders of Senior Notes.
 
EVENTS OF DEFAULT
   
  An Event of Default with respect to the Senior Notes is defined in the
Indenture as being: (a) default for 30 days in payment of any interest or any
Additional Amounts on the Global Note or the Definitive Registered Notes; (b)
default in payment of principal of the Global Note or the Definitive
Registered Notes at maturity; (c) material default in the performance, or
material breach, of any covenant or obligation of the Company in the Indenture
and continuance of such material default or breach for a period of 60 days
after written notice is given to the Company by the Trustee or to the Company
and the Trustee by the Holders of at least 25% in aggregate principal amount
of the Senior Notes; (d) default in the payment of the principal of any bond,
debenture, note or other evidence of indebtedness, in each case for money
borrowed, or in the payment of principal under any mortgage, indenture or
instrument under which there may be issued or by which there may be secured or
evidenced any indebtedness for money borrowed, of the Company or any
Significant Subsidiary which default for payment of principal is in an
aggregate principal amount exceeding US$50,000,000 (or its equivalent in any
other currency or currencies) when such indebtedness becomes due and payable
(whether at maturity, upon redemption or acceleration or otherwise), if such
default shall continue unremedied or unwaived for more than 30 Business Days
and the time for payment of such amount has not been expressly extended; and
(e) the failure of the Company or a Significant Subsidiary generally to pay
its debts as they become due, or the admission in writing of its inability to
pay its debts generally, or the making of a general assignment for the benefit
of its creditors, or the institution of any proceeding by or against the
Company or a Significant Subsidiary (other than any such proceeding brought
against the Company or a Significant Subsidiary that is dismissed within 180
days from the commencement thereof) seeking to adjudicate it bankrupt or
insolvent, or seeking liquidation (other than a solvent liquidation), winding
up, reorganization, arrangement, adjustment, protection, relief or composition
of it or its debts under any law relating to bankruptcy, insolvency,
reorganization, moratorium or relief of debtors, or seeking the entry of an
order for relief or appointment of an administrator, receiver, trustee,
intervenor or other similar official for it or for any substantial part of its
property, or the taking of any action by the Company or a Significant
Subsidiary to authorize any of the actions set forth in this subparagraph (e).
    
  If an Event of Default with respect to the Senior Notes shall occur and be
continuing, either the Trustee or the Holders of at least 25% in aggregate
principal amount of the Senior Notes may declare the principal amount of the
Senior Notes, and any interest accrued thereon, to be due and payable
immediately. At any time after such declaration of acceleration has been made,
but before a judgment or decree for payment of money has been obtained, if all
Events of Default have been cured (other than the non-payment of principal of
the Senior Notes
 
                                      63
<PAGE>
 
which has become due solely by reason of such declaration of acceleration)
then such declaration of acceleration shall be automatically annulled and
rescinded.
   
  No Holder of the Senior Notes shall have any right to institute any
proceeding, judicial or otherwise, with respect to the Indenture, or for the
appointment of a receiver or trustee, or for any other remedy thereunder,
unless (a) such Holder has previously given written notice to the Trustee of a
continuing Event of Default with respect to the Senior Notes; (b) the Holders
of not less than 25% in principal amount of the Senior Notes shall have made
written request to the Trustee to institute proceedings in respect of such
Event of Default in its own name as Trustee; (c) such Holder or Holders have
offered the Trustee indemnity satisfactory to the Trustee against the costs,
expenses and liabilities to be incurred in compliance with such request; (d)
the Trustee, for 60 days after its receipt of such notice, request and offer
of indemnity, has failed to institute any such proceeding; and (e) no
direction inconsistent with such written request has been given to the Trustee
during such 60 day period by the Holders of a majority in principal amount of
the outstanding Senior Notes.     
 
ADDITIONAL AMOUNTS
 
  All payments of principal and interest in respect of the Global Note and the
Definitive Registered Notes shall be made free and clear of, and without
withholding or deduction for or on account of, any present or future taxes,
duties, assessments or governmental charges of whatever nature imposed,
levied, collected, withheld or assessed by or within the UK or by or within
any political subdivision thereof or any authority therein or thereof having
power to tax ("UK Taxes"), unless such withholding or deduction is required by
law. In the event of any such withholding or deduction the Company shall pay
to the relevant Holder of the Global Note or to the relevant Holders of the
Definitive Registered Notes, as the case may be, such additional amounts
("Additional Amounts") as will result in the payment to each such Holder of
the amount that would otherwise have been receivable by such Holder in the
absence of such withholding or deduction, except that no such Additional
Amounts shall be payable:
     
    (a) to, or to a Person on behalf of, a Holder who is liable for such UK
  Taxes in respect of the Senior Notes by reason of such Holder having some
  connection with the UK (including being a citizen or resident or national
  of, or carrying on a business or maintaining a permanent establishment in,
  or being physically present in, the UK) other than the mere holding of a
  Senior Note or the receipt of principal and interest in respect thereof;
      
    (b) to, or to a Person on behalf of, a Holder who presents a Senior Note
  (where presentation is required) for payment more than 30 days after the
  Relevant Date (as defined below) except to the extent that such Holder
  would have been entitled to such Additional Amounts on presenting such
  Senior Note for payment on the last day of such period of 30 days;
 
    (c) to, or to a Person on behalf of, a Holder who presents a Senior Note
  (where presentation is required) in the United Kingdom;
 
    (d) to, or to a Person on behalf of, a Holder who would not be liable or
  subject to the withholding or deduction by making a declaration of non-
  residence or similar claim for exemption to the relevant tax authority; or
     
    (e) to, or to a Person on behalf of, a Holder of a Definitive Registered
  Note issued pursuant to the request of owners of interests representing a
  majority in outstanding principal amount in the Book-Entry Interest
  following and during the continuance of an Event of Default if such Holder
  (or any predecessor Holder) was one of such owners requesting that
  Definitive Registered Notes be so issued.     
   
  Such Additional Amounts will also not be payable where, had the beneficial
owner of the Senior Notes (or any interest therein) been the Holder of the
Senior Notes, he would not have been entitled to payment of Additional Amounts
by reason of any one or more of clauses (a) through (e) above. If the Company
shall determine that Additional Amounts will not be payable because of the
immediately preceding sentence, the Company will inform such Holder promptly
after making such determination setting forth the reason(s) therefor.     
 
                                      64
<PAGE>
 
  "Relevant Date" means whichever is the later of (i) the date on which such
payment first becomes due and (ii) if the full amount payable has not been
received in The City of New York by the Book-Entry Depositary or the Trustee
on or prior to such due date, the date on which, the full amount having been
so received, notice to that effect shall have been given to the Holders in
accordance with the Indenture.
 
OPTIONAL REDEMPTION
 
  The Senior Notes will be redeemable in whole or in part, at the option of
the Company at any time, at a redemption price equal to the greater of (i)
100% of the principal amount of the Senior Notes being redeemed or (ii) the
sum of the present values of the remaining scheduled payments of principal of
and interest on the Senior Notes being redeemed discounted to the date of
redemption on a semi-annual basis (assuming a 360-day year consisting of
twelve 30-day months) at a discount rate equal to the Treasury Yield plus
      basis points, plus, for (i) or (ii) above, whichever is applicable,
accrued interest on the Senior Notes to the date of redemption.
   
  "Treasury Yield" means, with respect to any Redemption Date, the rate per
annum equal to the semiannual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed
as a percentage of its principal amount) equal to the Comparable Treasury
Price for such Redemption Date.     
 
  "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable
to the remaining term of such Senior Notes to be redeemed that would be
utilized, at the time of selection and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable
maturity to the remaining term of the Senior Notes.
   
  "Comparable Treasury Price" means, with respect to any redemption date, (i)
the average of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) on the third
business day preceding such Redemption Date, as set forth in the daily
statistical release (or any successor release) published by the Federal
Reserve Bank of New York and designated "Composite 3:30 p.m. Quotations for US
Government Securities" or (ii) if such release (or any successor release) is
not published or does not contain such prices on such business day, the
Reference Treasury Dealer Quotation for such redemption date.     
 
  "Independent Investment Banker" means an independent investment banking
institution of national standing appointed by the Company and reasonably
acceptable to the Trustee.
 
  "Reference Treasury Dealer Quotation" means, with respect to the Reference
Treasury Dealer and any redemption date, the average, as determined by the
Trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount and quoted in
writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the
third business day preceding such redemption date).
   
  "Reference Treasury Dealer" means a primary US Government securities dealer
in New York City appointed by the Company and reasonably acceptable to the
Trustee.     
   
  Notice of redemption shall be given in accordance with "Reports and Notices"
above not less than 15 days nor more than 30 days prior to the date fixed for
redemption.     
 
  If fewer than all the Senior Notes are to be redeemed, selection of Senior
Notes for redemption will be made by the Trustee in any manner the Trustee
deems fair and appropriate and that complies with applicable legal and
securities exchange requirements.
   
  Unless the Company defaults in payment of the redemption price, from and
after the Redemption Date, the Senior Notes or portions thereof called for
redemption will cease to bear interest, and the holders thereof will have no
right in respect to such Senior Notes except the right to receive the
redemption price thereof.     
 
                                      65
<PAGE>
 
   
  Under the procedures set forth above, the price (the "Redemption Price")
payable upon the optional redemption at any time of a Senior Note is
determined by calculating the present value (the "Present Value") at such time
of each remaining payment of principal of or interest on such Senior Note and
then totaling such Present Values. If the sum of such Present Values is equal
to or less than 100% of the principal amount of such Senior Note, the
Redemption Price of such Senior Note will be 100% of its principal amount
(redemption at par). If the sum of such Present Values is greater than 100% of
the principal amount of such Senior Note, the Redemption Price of such Senior
Note will be such greater amount (redemption at a premium). In no event may a
Senior Note be redeemed optionally at less than 100% of its principal amount.
       
  The Present Value at any time of a payment of principal of or interest on a
Senior Note is calculated by applying to such payment the discount rate (the
"Discount Rate") applicable to such payment. The Discount Rate applicable at
any time to a payment of principal of or interest on a Senior Note equals the
equivalent yield to maturity at such time of a fixed rate United States
treasury security having a maturity comparable to the maturity of such payment
plus    basis points, such yield being calculated on the basis of the interest
rate borne by such United States treasury security and the price at such time
of such security. The United States treasury security employed in the
calculation of a Discount Rate (a "Relevant Security") as well as the price
and equivalent yield to maturity of such Relevant Security will be selected or
determined by an investment banker of national standing selected by the
Company which is reasonably acceptable to the Trustee.     
   
  Whether the sum of the Present Values of the remaining payments of principal
of and interest on a Senior Note to be redeemed optionally will or will not
exceed 100% of its principal amount and, accordingly, whether such Senior Note
will be redeemed at par or at a premium will depend on the Discount Rate used
to calculate such Present Values. Such Discount Rate, in turn, will depend
upon the equivalent yield to maturity of a Relevant Security which yield will
itself depend on the interest rate borne by, and the price of, the Relevant
Security. While the interest rate borne by the Relevant Security is fixed, the
price of the Relevant Security tends to vary with interest rate levels
prevailing from time to time. In general, if at a particular time the
prevailing level of interest rates for a newly issued United States treasury
security having a maturity comparable to that of a Relevant Security is higher
than the level of interest rates for newly issued United States treasury
securities having a maturity comparable to such Relevant Security prevailing
at the time the Relevant Security was issued, the price of the Relevant
Security will be lower than its issue price. Conversely, if at a particular
time the prevailing level of interest rates for a newly issued United States
treasury security having a maturity comparable to that of a Relevant Security
is lower than the level of interest rates prevailing for newly issued United
States treasury securities having a maturity comparable to the Relevant
Security at the time the Relevant Security was issued, the price of the
Relevant Security will be higher than its issue price.     
   
  Because the equivalent yield to maturity on a Relevant Security depends on
the interest rate it bears and its price, an increase or a decrease in the
level of interest rates for newly issued United States treasury securities
with a maturity comparable to that of a Relevant Security above or below the
levels of interest rates for newly issued United States treasury securities
having a maturity comparable to the Relevant Security prevailing at the time
of issue of the Relevant Security will generally result in an increase or a
decrease, respectively, in the Discount Rate used to determine the Present
Value of a payment of principal of or interest on a Senior Note. As noted
above, if the sum of the Present Values of the remaining payments of principal
of and interest on a Senior Note proposed to be redeemed is less than its
principal amount, such Senior Note may only be redeemed at par.     
       
OPTIONAL TAX REDEMPTION
   
  If (a) the Company satisfies the Trustee prior to the giving of a notice as
provided below that it has or will become obliged to pay Additional Amounts as
a result of either (x) any change in, or amendment to, the laws or regulations
of the UK or any political subdivision or any authority or agency thereof or
therein having power to tax or levy duties, or any change in the application
or interpretation of such laws or regulations, which change or amendment
becomes effective on or after the date of this Prospectus or (y) the issuance
of Definitive Registered Notes pursuant to the first sentence or clause (a) or
(b) of the third sentence of "--Definitive Senior Notes" above, and (b) such
obligation cannot be avoided by the Company taking reasonable measures
available to it, the Company may, at its option, on giving not more than 30
nor less than 15 days' notice to the Holders, redeem all, but not some only,
of the Senior Notes, in each case at their principal amount, together with
accrued and     
 
                                      66
<PAGE>
 
unpaid interest, provided that no such notice of redemption shall be given
earlier than 90 days prior to the earliest date on which the Company would be
obliged to pay such Additional Amounts were a payment in respect of the Senior
Notes then due. Prior to the publication of any notice of redemption pursuant
to this paragraph, the Company shall deliver to the Trustee a certificate
signed by a director of the Company stating that the obligation referred to in
(a) above cannot be avoided by the Company taking reasonable measures
available to it, and the Trustee shall accept such certificate as sufficient
evidence of the satisfaction of the condition precedent set out in (b) above,
in which event it shall be conclusive and binding on the Holders.
 
  In the event the Global Note is redeemed in whole or in part pursuant to
this provision or "Optional Redemption" above, the Book-Entry Depositary will
redeem, from the amount received by it in respect of the redemption of the
Global Note, an equal amount of the Book-Entry Interest issued to DTC. The
redemption price payable in connection with the redemption of Book-Entry
Interest will be equal to the amount received by the Book-Entry Depositary in
connection with the redemption of the Global Note.
 
DEFEASANCE
   
  The Company, at its option, (a) will be discharged from any and all
obligations in respect of the Senior Notes (except in each case for the
obligations to register the transfer or exchange of Senior Notes, replace
stolen, lost or mutilated Senior Notes, maintain paying agencies and hold
moneys for payment in trust) or (b) need not comply with certain covenants of
the Indenture described under "Limitation on Consolidation, Merger,
Conveyance, Sale or Lease", "Limitation on Liens" and "Limitation on Sale and
Lease-Back Transactions" in each case, if the Company irrevocably deposits
with the Trustee, in trust, (i) money or (ii) in certain cases, (A) U.S.
Government Obligations which through the payment of interest and principal in
respect thereof in accordance with their terms will provide money in an
amount, or (B) a combination thereof, in each case sufficient to pay and
discharge the principal and interest on the outstanding Senior Notes on the
dates such payments are due in accordance with the terms of the Senior Notes
(or if the Company has designated a redemption date pursuant to the final
sentence of this paragraph, to and including the redemption date so designated
by the Company), and no Event of Default or event which with notice or lapse
of time would become an Event of Default (including by reason of such deposit)
with respect to the Senior Notes shall have occurred and be continuing on the
date of such deposit. To exercise any such option, the Company is required to
deliver to the Trustee (x) an opinion of counsel (who may be counsel to the
Company) to the effect that the Holders will not recognize income, gain or
loss for federal income tax purposes as a result of such deposit, defeasance
and discharge, which in the case of (a) must be based on a change in law or a
ruling by the U.S. Internal Revenue Service, and (y) an Officers' Certificate
as to compliance with all conditions precedent provided for in the Indenture
relating to the satisfaction and discharge of the Senior Notes. If the Company
shall wish to deposit or cause to be deposited money or U.S. Government
Obligations to pay or discharge the principal of and interest, if any, on the
outstanding Senior Notes to and including the Redemption Date on which all of
the outstanding Senior Notes are to be redeemed, such Redemption Date shall be
irrevocably designated by a Board Resolution delivered to the Trustee on or
prior to the date of deposit of such money or U.S. Government Obligations, and
such Board Resolution shall be accompanied by an irrevocable Company Request
that the Trustee give notice of such redemption in the name and at the expense

MODIFICATION OR WAIVER OF CERTAIN COVENANTS     
   
  The Company may omit in any particular instance to comply with any term,
provision or condition set forth in the Indenture with respect to the Senior
Notes if before the time for such compliance the Holders of at least a
majority in aggregate principal amount of the outstanding Senior Notes shall,
by Act of such Holders, either modify the covenant or waive such compliance in
such instance or generally waive compliance with such term, provision or
condition, provided that no such modification shall without the consent of
each Holder (a) change the stated maturity upon which the principal of or the
interest on the Senior Notes is due and payable, (b) reduce the principal
amount thereof or the rate of interest thereon, (c) change any obligation of
the Company to pay Additional Amounts, (d) change any place of payment or the

(f) reduce the percentage in principal amount of the outstanding Senior Notes,
the consent of whose Holders is required for any waiver of compliance with
certain provisions of the Indenture or certain defaults thereunder and their
consequences provided for in the Indenture. The Senior Notes owned by the
Company or any of its Affiliates shall be deemed not to be outstanding for,
among other purposes, consenting to any such modification.

                       CERTAIN INCOME TAX CONSIDERATIONS
 
  THIS SUMMARY IS OF A GENERAL NATURE AND IS INCLUDED HEREIN SOLELY FOR
INFORMATIONAL PURPOSES. IT IS NOT INTENDED TO BE, NOR SHOULD IT BE CONSTRUED
TO BE, LEGAL OR TAX ADVICE. NO REPRESENTATION WITH RESPECT TO THE CONSEQUENCES
TO ANY PARTICULAR PURCHASER OF THE BOOK-ENTRY INTEREST IS MADE. PROSPECTIVE
PURCHASERS SHOULD CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THEIR
PARTICULAR CIRCUMSTANCES AND THE EFFECTS OF STATE, LOCAL OR FOREIGN LAWS,
INCLUDING UK TAX LAWS TO WHICH THEY MAY BE SUBJECT.
 
UK INCOME TAX CONSIDERATIONS
   
  The comments below are of a general nature based on current UK law and
Inland Revenue practice and represent the opinion of Allen & Overy, special UK
counsel to the Company, so far as such comments relate to matters of law or
legal conclusions. They relate only to the position of persons who are the
absolute beneficial owners of their Senior Notes and related interest and may
not apply to certain classes of persons such as dealers. Any holders of Senior
Notes who are in doubt as to their tax position should consult their
professional advisers.     
 
PAYMENTS ON THE SENIOR NOTES
   
  For UK tax purposes, while the Senior Notes remain represented by the Global
Note in bearer form and continue to be listed on the Luxembourg Stock Exchange
or some other stock exchange recognized by the UK Inland Revenue, payments of
interest (whether on the Global Note to the Book-Entry Depositary or on the
Book-Entry Interest to DTC) may be made without withholding or deduction for
or on account of UK income tax for so long as the Company's paying agent and
the Book-Entry Depositary, if different, are outside the UK.     
 
  In other cases, and in particular if Definitive Registered Notes are issued,
interest will be paid after deduction of UK income tax (currently at the lower
rate of 20%). A US holder will normally be eligible to recover in full any UK
tax withheld from payments of interest to which such holder is beneficially
entitled by making a claim under the US/UK Double Tax Treaty on the
appropriate form. Alternatively, a claim may be made by a US holder in advance
of a payment of interest. If the claim is accepted by the Inland Revenue, they
will authorize subsequent payments to that US holder to be made without
withholding of UK income tax. Claims for repayment must be made within six
years of the end of the UK year of assessment (generally April 5 in each year)
to which the interest relates and must be accompanied by the original
statement provided by the Company when the interest payment was made showing
the amount of UK income tax deducted. Because a claim is not considered until
the UK tax authorities receive the appropriate form from the Internal Revenue
Service, forms should be sent to the Internal Revenue Service, in the case of
an advance claim, well before the relevant interest payment date or, in the
case of a claim for the repayment of the tax, well before the end of the
appropriate limitation period.
 
  Holders in other jurisdictions may be entitled to a refund of any UK income
tax deducted or withheld or to make a claim for interest on the Senior Notes
to be paid without, or subject to a reduced rate of, deduction or withholding
under the provisions of an applicable double tax treaty.
 
  Refund of all or part of any UK income tax deducted or withheld may,
depending on individual circumstances, be available to a holder of Senior
Notes who is resident in the UK or who carries on a trade, profession or
vocation in the UK through a branch or agency to which the Senior Notes are
attributable, or who is a Commonwealth citizen or otherwise entitled to a UK
personal allowance.
   
  Holders should be aware that under current UK tax law upon the issuance of
Definitive Registered Notes such holders may become subject to UK withholding
tax on any payments of interest with respect to such Senior Notes. However,
such holders will be entitled to the payment of Additional Amounts in respect
of the tax withheld, except as set forth under "Description of the Senior
Notes--Additional Amounts," and subject to the     
right of the Company in certain circumstances to redeem the Senior Notes
early. See "Description of the Senior Notes--Optional Tax Redemption."
 
                                      69
<PAGE>
 
  Interest on the Senior Notes constitutes UK source income for tax purposes
and, as such, may be subject to UK income tax by direct assessment even where
paid without deduction or withholding.
   
  However, UK tax chargeable on interest from a UK source received by persons
not regarded as resident in the UK for tax purposes will normally be limited
to the tax, if any, deducted at source on payment of such interest. This will
not apply if interest is received by a Holder who is not resident for tax
purposes in the UK if that Holder carries on a trade, profession or vocation
in the UK through a UK branch or agency in connection with which the interest
is received or to which the Senior Notes are attributable. There are
exemptions for interest received by certain categories of agent (such as some
brokers and investment managers).     
 
UK CORPORATION TAXPAYERS
 
  In general Holders which are within the charge to UK corporation tax will be
charged to tax on all returns on and fluctuations in value of the Senior Notes
broadly in accordance with their statutory accounting treatment. Such Holders
will generally be charged to tax in each accounting period by reference to
interest and discount accrued in that period.
 
  Any gains or losses on Senior Notes held by UK resident corporate Holders or
certain other Holders who are within the charge to UK corporation tax, which
are attributable to fluctuations in the value of US dollars relative to, in
most cases sterling, will, subject to reliefs and exclusions contained in the
relevant legislation, be included in the calculation of such Holders' taxable
income on an accruals basis for each accounting period during which the Senior
Notes are held. Any gain or loss arising on a disposal (including redemption)
of such Senior Notes would be outside the scope of UK taxation of chargeable
gains.
 
OTHER UK TAX PAYERS
 
 Taxation of Chargeable Gains
   
  A disposal of Senior Notes by a Holder who is not within the charge to
corporation tax but who is resident or ordinarily resident in the UK, or
carries on a trade, profession or vocation in the UK through a branch or
agency to which the Senior Notes are attributable, may give rise to a
chargeable gain or allowable loss for the purposes of the UK taxation of
chargeable gains.     
 
 Accrued Income Scheme
   
  On a disposal of Senior Notes by a Holder who is not within the charge to
corporation tax, any interest which has accrued since the last interest
payment date may be chargeable to tax as income if that Holder is resident or
ordinarily resident in the UK or carries on a trade in the UK through a branch
or agency to which the Senior Notes are attributable.     
 
 Taxation of discount
 
  Based on the Company's understanding of the Inland Revenue's practice in
this area, it is considered that the Senior Notes will not be treated as
constituting "relevant discounted securities" for the purposes of Schedule 13
of the Finance Act 1996. Therefore, individual Holders who are within the
scope of UK income tax as described above should not be liable to UK income
tax on gains made on sales or other disposals (including redemption) of the
Senior Notes.
 
UK STAMP DUTY AND STAMP DUTY RESERVE TAX
 
  No UK Stamp Duty or Stamp Duty Reserve Tax is payable on the issue or
transfer by delivery of a Senior Note or on its redemption.
 
US FEDERAL INCOME TAX CONSIDERATIONS
 
  The following summary describes the material US federal income tax
consequences of the acquisition, ownership and disposition of Senior Notes to
initial purchasers who are US citizens or residents, corporations,
 
                                      70
<PAGE>
 
   
partnerships or other entities created or organized in or under the laws of
the US or any state thereof, or an estate or trust, the income of which is
subject to US federal income taxation regardless of its source, and who are
residents in the US and not resident in the UK for purposes of the current
double taxation convention between the US and the UK ("US Holders") and who
hold their beneficial interests in the Senior Notes as capital assets. The
discussion represents the opinion of Troutman Sanders LLP, counsel to the
Company, so far as it relates to matters of law or legal conclusions and is
based upon the provisions of the US Internal Revenue Code of 1986, as amended
(the "Code"), regulations, rulings and judicial decisions now in effect, all
of which are subject to change, possibly with retroactive effect. The summary
does not discuss all aspects of US federal income taxation that may be
relevant to particular investors in light of their particular investment
circumstances, nor does it discuss any aspects of state, local or foreign tax
laws or any estate or gift tax considerations. The summary does not deal with
non-US persons or with certain classes of US persons subject to special
treatment under the US federal income tax laws (for example, dealers in
securities, banks, life insurance companies or tax-exempt organizations). In
addition, because the tax consequences may differ depending on individual
circumstances, each prospective purchaser of the Senior Notes is strongly
urged to consult his own tax advisor with respect to his particular tax
situation.     
 
PAYMENTS OF INTEREST
 
  Except as set forth below, interest on the Senior Notes generally will be
taxable to a US Holder as ordinary income from US sources at the time it is
received or accrued in accordance with the US Holder's method of accounting
for US federal income tax purposes. In addition, if any Additional Amounts are
paid, such payment will be taxable as ordinary income in accordance with such
US Holder's method of accounting. Thus, a US Holder will be required to report
income in an amount greater than the cash it receives in respect of payments
on its Senior Notes. However, a US Holder, subject to certain limitations, may
be eligible to claim as a credit or deduction for purposes of computing its US
federal income tax liability UK Taxes withheld (if any). For that purpose,
interest income and the Additional Amounts will generally be treated as
foreign source passive income (or, in the case of certain US Holders,
financial services income). The rules relating to foreign tax credits are
extremely complex, and US Holders should consult with their own tax advisors
with regard to the availability of a foreign tax credit and the application of
the foreign tax credit to their particular situation.
 
SALE OR OTHER TAXABLE DISPOSITION OF THE SENIOR NOTES
 
  A US Holder's tax basis in the Senior Notes will, in general, be the US
Holder's cost therefor. A US Holder will recognize gain or loss on the sale,
exchange, redemption or other taxable disposition of the Senior Notes, equal
to the difference (if any) between the amount realized upon the sale, exchange
or retirement (converted into US dollars if any foreign currency is received)
and the adjusted tax basis of the Senior Notes. Such gain or loss will be
capital gain or loss and will be long-term capital gain or loss if, at the
time of sale, exchange or retirement, the Senior Notes have been held for more
than one year. Under current law, net capital gains are, in certain
circumstances, taxed at lower rates than ordinary income. The deductibility of
capital losses is subject to limitations. If the US dollar is not the
functional currency of the US Holder, such Holder may recognize ordinary gain
or loss due to the currency exchange fluctuation.
 
BACKUP WITHHOLDING AND INFORMATION REPORTING
 
  Under the Code, a US Holder may be subject, under certain circumstances, to
US backup withholding at a 31% rate with respect to payments by the Company or
any of its paying agents of interest or the gross proceeds of dispositions
thereof. This withholding only applies if the US Holder fails to furnish a
correct social security or other taxpayer identification number to the
Company, fails to report interest income in full or fails to certify to the
Company that such US Holder has provided a correct taxpayer identification
number and that such US Holder is not subject to withholding, the Company is
required to withhold a 31% federal backup withholding tax on certain amounts
paid to the US Holder. Special rules may apply with respect to the payment of
the proceeds from the sale of the Senior Notes to or through foreign offices
of certain brokers.
 
  The backup withholding tax is not an additional tax and may be credited
against a US Holder's regular US federal income tax liability or refunded by
the IRS where applicable.

</TABLE>
 
  In the Underwriting Agreement, the Underwriters have agreed, subject to the
terms and conditions set forth therein, to purchase all of the Senior Notes
being sold pursuant to the Underwriting Agreement if any of the Senior Notes
being sold pursuant to the Underwriting Agreement are purchased.
 
  The Underwriters have advised the Company that the Underwriters propose to
offer the Senior Notes to the public initially at the public offering price
set forth on the cover page of this Prospectus and to selected dealers at such
price less a concession of not more than   % of the principal amount of the
Senior Notes. The Underwriters may allow, and such dealers may reallow, a
concession not in excess of     % of the principal amount of the Senior Notes
to certain other dealers. After the initial offering, the offering price and
other selling terms may be changed by the Underwriters.
 
  The Senior Notes represent a new issue of securities. If the Senior Notes
are traded after their initial issuance, they may trade at a discount from
their initial public offering price depending upon prevailing interest rates,
the market for similar securities and other factors. In addition, no assurance
can be given that a holder of Senior Notes will be able to sell such Senior
Notes in the future or that such sale will be at a price equal to or higher
than the initial public offering price of such Senior Notes.
 
  Although the Underwriters have informed the Company that they currently
intend to make a market in the Senior Notes and interests in the Book-Entry
Interest, they are not obligated to do so, and any such market-making may be
discontinued at any time without notice. There can be no assurance as to the
development or liquidity of any market for the Senior Notes or interests in
the Book-Entry Interest. If an active public market does not develop, the
market price and liquidity of the Senior Notes or interests in the Book-Entry
Interest may be adversely affected.
 
  The Company has agreed to indemnify the Underwriters and its controlling
persons against certain liabilities, including liabilities under the
Securities Act.
   
  Under Rule 2710(c)(8) of the Corporate Financing Rules of the National
Association of Securities Dealers, Inc. (the "NASD"), no NASD members can
participate in a public offering of an issuer's securities where more than 10%
of the net offering proceeds, not including underwriting compensation, are
intended to be paid to NASD members participating in the distribution of the
offering or associated or affiliated persons of such members unless the yield
at which a debt issue is to be distributed to the public is established
pursuant to Rule 2720(c)(3) by a qualified independent underwriter ("QIU"). As
disclosed under the caption "Use of Proceeds," Morgan Guaranty, an affiliate
of JP Morgan, is a lender under the Company's term loan and will receive 10%
or more of the net proceeds of this Offering in repayment of a portion of such
term loan. Since JP Morgan is one of the underwriters in this Offering, this
Offering is being conducted pursuant to Rule 2710(c)(8).     
 
 
                                      72
<PAGE>
 
   
  Rule 2720(c)(3)(C), however, allows an NASD member to participate in the
distribution of securities of a company where it or its affiliates will
receive more than 10% of the net proceeds without a QIU establishing the yield
of the securities being offered if the offering is of a class of securities
rated Baa or better by Moody's or BBB or better by S&P. The debt securities
being offered hereby are expected to receive at least the ratings mentioned
above and, therefore, there will be no QIU recommending the minimum yield of
the debt securities being offered. See "Summary--The Offering--Ratings."     
       
  Each of the Underwriters has severally represented and agreed in the
Underwriting Agreement that (i) it has not offered or sold, and prior to the
date six months after the date of issue of the Senior Notes will not offer or
sell, any Senior Notes to persons in the UK except to persons whose ordinary
activities involve them in acquiring, holding, managing or disposing of
investments (as principal or agent) for the purposes of their businesses or
otherwise in circumstances which have not resulted in and will not result in
an offer to the public in the UK within the meaning of the Public Offers of
Securities Regulations 1995; (ii) it has complied and will comply with all
applicable provisions of the Financial Services Act 1986 (the "FSA") with
respect to anything done by it in relation to the Senior Notes in, from or
otherwise involving the UK; (iii) it has only issued or passed on and will
only issue or pass on in the UK any document received by it in connection with
the issue of the Senior Notes to a person who is of a kind described in
Article 11(3) of the Financial Services Act 1986 (Investment Advertisements)
(Exemptions) Order 1996 or is a person to whom such document may otherwise
lawfully be issued or passed on; and (iv) it has not issued or caused to be
issued and will not issue or cause to be issued in the UK any advertisement
inviting persons to subscribe or purchase the Senior Notes or containing
information calculated to lead directly or indirectly to persons subscribing
or purchasing the Senior Notes except to persons (a) who are authorized under
the FSA or (b) whose ordinary business involves the acquisition and disposal
of property of the same kind as the Senior Notes, and has not advised or
procured and will not advise or procure any person (except as aforesaid) in
the UK to subscribe or purchase the Senior Notes.
 
                                 LEGAL MATTERS
   
  Certain legal matters relating to the Senior Notes will be passed upon for
the Company by Troutman Sanders LLP, Atlanta, Georgia and for the Underwriters
by Shearman & Sterling, New York, New York. Certain legal matters relating to
English law, including taxation, corporate matters and the enforceability of
the Senior Notes and agreements related thereto, will be passed upon for the
Company by Allen & Overy, London, England.     
 
  Troutman Sanders, LLP and Shearman & Sterling will rely, without independent
investigation, upon Allen & Overy with respect to matters relating to English
law.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors of Southern Investments UK plc:
   
  We have audited the accompanying consolidated balance sheet of SOUTHERN
INVESTMENTS UK plc AND SUBSIDIARIES (Successor Company) as of March 31, 1996
and the related consolidated statements of income, changes in stockholder's
equity, and cash flows for the period from inception (June 23, 1995) to March
31, 1996. 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 audit.     
 
  We conducted our audit in accordance with auditing standards generally
accepted in the United States. 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 audit provides a
reasonable basis for our opinion.
   
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Southern Investments UK
plc and subsidiaries as of March 31, 1996 and the results of their operations
and their cash flows for the period from inception (June 23, 1995) to March
31, 1996 in conformity with accounting principles generally accepted in the
United States.

                NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
 
                                MARCH 31, 1996
 
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 General
   
  The Company is a wholly-owned subsidiary of Southern Investments UK Holdings
Limited ("Holdings"), which is wholly-owned indirectly by The Southern Company
("Southern") (see Note 13). The Company was incorporated as a public limited
company under the laws of England and Wales on June 23, 1995 as a vehicle for
the acquisition of South Western Electricity plc ("SWEB"), one of the 12
regional electricity companies ("RECs") in England and Wales licensed to
distribute, supply, and, to a limited extent, generate electricity. On
September 18, 1995, the Company gained effective control of SWEB, having
acquired approximately 84% of its shares (the "Acquisition"). Accordingly, the
Company has designated September 18, 1995 as the effective date of the
Acquisition (the "Acquisition Date"). Given that SWEB represents substantially
all of the current operations of the Company, SWEB is considered the
Predecessor Company (the "Predecessor Company"). All references in the
financial statements to the Successor Company represent the Company and to the
Predecessor Company represent South Western Electricity plc and its
subsidiaries. See Note 7 for a further discussion of the Acquisition.     
   
  SWEB is one of the twelve RECs in England and Wales licensed to distribute,
supply, and, to a limited extent, generate electricity. The RECs were created
as a result of the privatization of the UK electricity industry in 1990 after
the state owned low voltage distribution networks were allocated to the then
existing twelve regional boards. SWEB's main business, the distribution and
supply of electricity to customers in the southwest of England, is regulated
under the terms of SWEB's Public Electricity Supply license by the Office of
Electricity Regulation ("OFFER").     
 
  SWEB's operates primarily in its franchise area in southwest England. SWEB's
franchise area covers approximately 5,560 square miles running from Bristol
and Bath in the northeast, 188 miles southwest along the peninsula to Land's
End and 28 miles beyond to the Isles of Scilly, and has a resident population
of approximately 2.8 million.
 
 Basis of Presentation
   
  The financial statements of the Company are presented in conformity with
accounting principles generally accepted in the United States. The
accompanying financial statements have not been prepared in accordance with
the policies of Statement of Financial Accounting Standards No. 71,
"Accounting for the Effects of Certain Types of Regulation" ("SFAS No. 71").
This pronouncement, under which most U.S. electric utilities report financial
statements, applies to entities which are subject to cost-based rate
regulation. By contrast, SWEB is not subject to rate regulation, but, rather,
is subject to price cap regulation (Note 3) and therefore the provisions of
SFAS No. 71 do not apply. Financial statements presented in accordance with
SFAS No. 71 contain deferred items which have not yet been included in rates
charged to customers in compliance with the respective regulatory authorities,
but which would have been included in the income statement of enterprises in
general under U.S. GAAP. The accompanying financial statements of the Company
do not contain such deferrals.     
   
  The consolidated financial statements include the accounts of the Company
and its wholly owned and majority-owned subsidiaries and have been prepared
from records maintained by SWEB in the United Kingdom. All significant
intercompany accounts and transactions have been eliminated in consolidation.
Investments in companies in which the Company's ownership interests range from
20% to 50% and the Company exercises significant influence over operating and
financial policies are accounted for using the equity method. Other
investments are accounted for using the cost method (Note 11).

                              (SUCCESSOR COMPANY)
 
          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  These financial statements are presented in pounds sterling ((Pounds)) and
in U.S. dollars ($ or U.S. $), solely for the convenience of the reader, at
the exchange rate of (Pounds)1 = U.S. $1.5529, the noon buying rate in New
York City for cable transfers in pounds sterling as certified for customs
purposes by the Federal Reserve Bank of New York on June 28, 1996. No
representation is made that the pounds sterling amounts have been, could have
been, or could be converted into U.S. dollars at that or any other rate of
exchange.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and reported amounts of revenues and expenses during the reporting
period. Actual results could differ from those estimates.
 
 Revenue Recognition
 
  SWEB records revenue net of value added tax and accrues revenues for
services provided but unbilled at the end of each reporting period. SWEB
purchases power primarily from a market for the bulk trading of electricity
(the "Pool").
 
  The Company has a diversified base of customers. No single customer or
industry comprises 10% or more of revenues.
 
 Cash and Cash Equivalents
 
  The Company considers all short-term investments with an original maturity
of three months or less to be cash equivalents.
 
 Property, Plant, and Equipment
 
  Property, plant, and equipment are recorded at fair market value as adjusted
at the acquisition date (Note 7) in accordance with Accounting Principles
Board Opinion ("APB") No. 16, "Accounting for Business Combinations." Items
capitalized subsequent to the Acquisition are recorded at original cost, which
includes materials, labor, appropriate administrative and general costs, and
the estimated cost of funds used during construction. The cost of maintenance,
repairs, and replacement of minor items of property is charged to maintenance
expense.
   
  Depreciation of the recorded cost of depreciable property, plant, and
equipment is provided by using primarily composite straight-line rates (Note
9), which approximate 3.1% per year (2.5% per year for depreciable utility
plant in service).     
 
 Information Technology Consultancy and Development Costs
   
  Significant information technology ("IT") consultancy and development costs
are capitalized when they become technologically feasible and are amortized
over their estimated useful economic life from the date of first use. Other IT
consultancy and development costs are charged to income in the period in which
they are incurred. This policy has been adopted effective October 1, 1995 as
the Company has embarked on a significant program of investment and will be
incurring significant development costs which are fundamental to the future
performance of the business and which will benefit the business for a number
of years. The Directors are of the opinion that in relation to the planned
development costs to be incurred in the future, the policy followed by the
Predecessor Company of writing off such costs to the Statement of Income does
not give a fair reflection of the period over which the benefits will accrue.
Prior to this change in accounting policy the Company expensed all IT
consultancy and development costs as incurred. The effect of adopting this
policy has resulted in the capitalization of (Pounds)5.2m of costs in the year
ended March 31, 1996. If the policy had been adopted at September 30, 1995,
the amount that would have been capitalized would have been zero, as no
tangible benefits were believed to have accrued from current development work
at that date and any costs relating to earlier development work had been fully
amortized.

          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
 Goodwill
   
  The Company amortizes costs in excess of fair value of net assets of the
business acquired using the straight-line method over a period of 40 years.
Recoverability (performed on the basis of undiscounted operating cash flow
analysis) is reviewed annually or sooner if events or changes in circumstances
indicate that the carrying amount may exceed fair value, in accordance with
the provisions of Statement of Financial Accounting Standards ("SFAS") No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of." Goodwill shown in the accompanying consolidated
financial statements relates to the acquisition of SWEB (Note 7).     
 
 Investments
   
  The Company accounts for its current investments in accordance with SFAS No.
115, "Accounting for Investments for Certain Debt and Equity Securities."
These investments represent investments in debt securities, which management
classifies as available-for-sale securities in accordance with SFAS No. 115.
The Company's long-term investments consist of investments accounted for using
the cost method (See Note 11).     
 
 Income Taxes
 
  SFAS No. 109, "Accounting for Income Taxes," requires the asset and
liability approach for financial accounting and reporting for deferred income
taxes. The Company uses the liability method of accounting for deferred income
taxes and provides deferred income taxes for all significant income tax
temporary differences.
 
 Unearned Revenue
 
  Unearned revenue primarily represents the liability for payments received
from customers in connection with the assessment of a value added tax ("VAT")
on electricity sales, which was imposed by the UK government effective April
1, 1994 to include electricity sales to residential customers. As part of the
adoption of the tax, customers were allowed to prepay their bills and avoid
the VAT on the element of the future electricity consumption which was
prepaid. Revenues are recognized as electricity is supplied to these
customers.
 
  The Regulator permits the Company to bill for all estimated allowed revenue,
while actual allowed revenue is not known until after the end of the fiscal
year. When billings exceed the actual allowed revenue, revenues are deferred
on the excess amounts. The deferred amount is deducted from revenues and
included in current liabilities. When billings are less than the allowed
revenue, no anticipation of any potential future recovery is made.
 
 Financial Instruments
 
  The Company uses financial instruments primarily to mitigate the risk of
exposure to volatility in electricity prices and fluctuations in interest
rates. Such instruments are accounted for as hedges, and accordingly, gains
and losses are deferred and recognized over the same period as the item hedged
(Note 8).
 
  The Company's carrying amount of financial instruments at March 31, 1996 was
zero (Note 8).
 
 New Accounting Standards
   
  In March 1995, the Financial Accounting Standards Board issued SFAS No. 121,
which provides guidance on when to assess and how to measure impairment of
long-lived assets, certain identifiable intangibles, and

goodwill related to those assets to be held and used, and for long-lived
assets and certain intangibles to be disposed of. The Company adopted SFAS No.
121 on January 1, 1996, with no material effect on its financial position or
results of operations.
 
2. RETIREMENT BENEFITS
 
 Pension Plans
 
  SWEB has two pension plans, a defined benefit plan and a defined
contribution plan.
 
 Defined Contribution Plan
   
  The defined contribution plan was established in the year ended March 31,
1994. The assets of the defined contribution plan are held and administered by
an independent trustee. Contributions to the plan by SWEB on behalf of its
employees were (Pounds)0.1 million ($0.2 million) for the period from
inception (June 23, 1995) through March 31, 1996.     
 
 Defined Benefit Plan
   
  SWEB participates in the Electricity Supply Pension Scheme, which provides
pension and other related defined benefits, based on final pensionable pay, to
substantially all employees throughout the Electricity Supply Industry in the
United Kingdom. Contributions to the plan by SWEB on behalf of its employees
were (Pounds)4.8 million ($7.5 million) for the period from inception (June
23, 1995) through March 31, 1996.     
 
 
  In accordance with SFAS No. 87, as of the date of the Acquisition, the
assignment of the purchase price to individual assets acquired and liabilities
assumed includes the plan assets in excess of the projected benefit
obligation. SWEB uses the "entry age normal method with a frozen initial
liability" actuarial method for funding purposes. Amounts funded to the
pension trust(s) are primarily invested in equity and fixed-income securities.
SFAS No. 87 requires use of the "projected unit credit" actuarial method for
financial reporting purposes.
 
  The following table shows the actuarial results and assumptions for pension
benefits as computed under SFAS No. 87 (in millions):

</TABLE>
 
3. REGULATORY MATTERS
 
  OFFER controls the revenues generated by SWEB in its distribution and supply
businesses by applying a price control formula, P + RPI - X (where X is
currently 3% for distribution and 2% for supply), where P is the price level
at the beginning of each new regulatory period, RPI is the change in the
Retail Price Index and X is an adjustment factor determined by OFFER.
   
  In the distribution business, the Distribution Price Control Formula
("DPCR") is usually set for a five-year period, subject to more frequent
adjustments as determined necessary by the Director General of Electricity
Supply (the "Regulator"). At each review, the Regulator can require a one-time
price reduction. An initial review by the Regulator of allowable income in the
distribution business led to a reduction of the price level by 14% for SWEB
starting April 1, 1995, followed by efficiency factors of X = 2% for each year
until March 2000. On July 6, 1995, the Regulator announced the result of a
further distribution price review which was precipitated by certain market
events in the UK electric utility industry. For SWEB, such announcement meant
a further real reduction of 11% in allowable distribution income for the
twelve months from April 1, 1996, followed by an efficiency factor of X = 3%
for each year until March 31, 2000, before an allowed increase for inflation.
       
  In the supply business, which is progressively being opened to competition,
price regulation still applies to the market for customers with a demand of
not more than 100kW. The calculation of the maximum supply charge is based on
a Supply Price Control Formula, similar to the DPCR and is set for a four-year
period. In 1993, OFFER announced the supply franchise market (i.e., with
demand of not more than 100kW) income entitlement for the four-year period
ending March 1998. A relatively small efficiency factor of X = 2% was applied
to SWEB and is being offset by an allowance for both unit and customer growth.
The nonfranchise markets (above 1MW) were opened to full competition during
privatization in 1990; the nonfranchise markets above 100 kW were opened to
full competition starting in April 1994.     
 
4. COMMITMENTS AND CONTINGENT MATTERS
 
 Power Purchase Agreements
   
  SWEB has entered into a contract relating to the purchase of 200 megawatts
of capacity from a 7.69% owned related party, Teesside Power Limited
("Teesside"), for a period of 15 years beginning April 1, 1993. The contract
sets escalating electricity purchase prices at predetermined levels. The
Company has recognized an accrual at the acquisition date for the excess of
these Teesside power purchase costs in each year over an estimate of the
equivalent pool costs in that respective year. These costs have been
discounted at an appropriate rate to today's present value of (Pounds)60
million ($93 million).

          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  The Company has additional contracts with unaffiliated parties relating to
the purchase of electricity, which expire by March 31, 1998, and contracts
relating to the purchase of gas which expire by September 30, 1998, the terms
of which are immaterial with respect to quantity and price, both annually and
in the aggregate.
 
 Operating Leases
   
  SWEB has commitments under operating leases with various terms and
expiration dates. Expenses associated with these commitments totaled (Pounds)3
million ($5 million) for the period from inception (June 23, 1995) to March
31, 1996. At March 31, 1996, estimated minimum rental commitments for
noncancelable operating leases were as follows:

 Labor Subject to Collective Bargaining Agreements
 
  Substantially all of SWEB's employees are subject to one of five collective
bargaining agreements. Such agreements are ongoing in nature, and SWEB's
employee participation level is consistent with that of the electric utility
industry in Great Britain.
 
5. SEGMENT REPORTING
   
  The Company is primarily engaged in two electric industry segments:
distribution, which involves the transmission of electricity across its
network and its transfer and delivery to its customers, and supply, which
involves bulk purchase of electricity from the Pool and arranging for its sale
and transfer to its customers. Intersegment sales primarily represent sales
from distribution to supply for the use of the distribution network.
Information about the Company's operations in these individual segments during
the period from inception (June 23, 1995) through March 31, 1996 and as of
March 31, 1996 is detailed below (in millions):

7. ACQUISITION
   
  The Acquisition of SWEB in the amount of (Pounds)1.063 ($1.651) billion was
accomplished through the purchase of shares via both cash and non-cash
consideration (see accompanying consolidated statement of cash flows) between
July and November 1995. The Company purchased 14% of SWEB through open market
purchases during July and August 1995. On August 25, 1995, the Company
acquired an additional 16% of SWEB through open market purchases. On August
31, 1995, the Company's offer to purchase all shares of SWEB was endorsed by
its Directors. By September 18, 1995, the Company had gained effective control
of approximately 84% of its shares, and, therefore, effective control of SWEB.
The Company acquired the remaining shares by November 27, 1995, the date on
which the notice for compulsory acquisition from non-assenting shareholders
expired. The Company's equity in the earnings of SWEB prior to September 18,
1995 and the minority interest in the earnings

of SWEB subsequent to the Acquisition Date were each immaterial and,
accordingly, are not separately presented in the accompanying consolidated
statement of income.     
   
  The Acquisition was accounted for using the purchase method of accounting in
accordance with APB No. 16, "Accounting for Business Combinations." The
purchase price of SWEB has been allocated to the underlying assets and
liabilities based on estimated fair values at the acquisition date. Management
does not anticipate any material revisions to such estimates. The acquisition
cost exceeded the fair market value of net assets acquired, including

  The Company recognized certain liabilities in connection with the
Acquisition, including a plan to increase the ongoing severance program and
costs to exit its electrical contracting and servicing business lines. A
program of staff reductions is being effected which, when completed by the end
of calendar 1997, is expected to reduce the number of staff in the main
electricity business by 21% compared to that at the date of acquisition by the
Company. The Company recorded this provision related to exiting these
businesses in accordance with EITF Consensus No. 95-3, "Recognition of
Liabilities in Connection With a Purchase Business Combination." During the
period, the Company sold South Western Electricity (Connect) Limited to its
existing management and SWEB Servicing Limited to an unaffiliated party. The

  The following pro forma information has been prepared assuming that the
Acquisition had occurred at the beginning of the respective periods. This pro
forma information includes adjustments for depreciation expense resulting from
the fair valuation of the assets upon acquisition, amortization of goodwill
resulting from the excess of the fair values of the assets minus liabilities
over the purchase price, incremental interest expense resulting from the fair
valuation of debt obligations upon acquisition, interest expense that would
have been incurred to finance the acquisition as if they were incurred at the
beginning of the period, and the exclusion of the Company's gain on sale of
its investment in NGG and its acquisition bid defense costs. The pro forma
information is presented for informational purposes only and may not be
indicative of the results of operations as they would have been had the
Acquisition occurred at the beginning of the respective periods, nor is the
information necessarily indicative of the results of operations which may

8. FINANCIAL INSTRUMENTS
   
  SWEB utilizes contracts for differences ("CFDs") to mitigate its exposure to
volatility in the prices of electricity purchased through the Pool. Such
contracts allow the Company to effectively convert the majority of its
anticipated Pool purchases from market prices to fixed prices. CFDs are in
place to hedge a portion of electricity purchases on approximately 33,000 GWh
through the year 2008. Accordingly, the gains and losses on such contracts are
deferred and recognized as electricity purchased. It is not possible to
estimate the fair value of these contracts at present as the contract prices
are based on future events, the effects of which currently are not estimable.
Current CFD's have been entered into with UK Power Generators.     
 
  Interest rate swaps are used by the Company to hedge its exposure to
fluctuations in interest rates by allowing the Company to effectively convert
its outstanding variable-rate debt into fixed rates. At March 31, 1996,
sterling interest rate swaps expiring February 8, 2006 with notional amounts
totaling (Pounds)250 million ($388 million), resulted in an unrealized gain of
(Pounds)11 million ($17 million).
 
  The fair value of the swaps is estimated using pricing models which provide
the present value of the difference between the contracted swap rates and
market interest rates over the remaining life of the swaps and represent the
amounts the bank would pay to terminate the swaps at March 31, 1996. Should
the Company terminate the swaps, the gain or loss on termination would be
deferred and amortized to interest expense over the period of the related
debt.
 
  The Company is exposed to losses in the event of nonperformance by
counterparties to both its CFDs and interest rate swaps. To manage this credit
risk, the Company selects counterparties based on their credit ratings, limits
its exposure to any one counterparty under defined guidelines, and monitors
the market position of the programs and its relative market position with each
counterparty.
 
9. PROPERTY, PLANT, AND EQUIPMENT
 
  The Company records book depreciation expense on a straight-line basis,

  At March 31, 1996, nonnetwork land and buildings include approximately
(Pounds)2 million ($3 million) of property and equipment held for sale.
Management believes that the carrying amount of these assets approximates
their net realizable value. There is an arrangement in place whereby HM
Government is entitled to a share in the profits realized by the Company on
certain property disposals made up to March 2000. Full provision for such
clawback liabilities is made as soon as the sale is recognized.

</TABLE>
   
  The weighted average balance of debt outstanding during the period was
(Pounds)605 million ($940 million) at a weighted average interest rate of
8.7%.     
 
  At March 31, 1996, the Company had in place a (Pounds)325 million ($505
million) term loan facility with certain banks. Interest is payable monthly
based on an interest rate of LIBOR plus 0.23%, which was 6.355% at March 31,
1996. Outstanding borrowings are due February 5, 1997.
 
  SWEB has in place a (Pounds)275 million ($427 million) revolving credit
facility with certain banks, under which (Pounds)160 million ($248 million)
had been drawn at March 31, 1996 at an interest rate of 6.46% (LIBOR plus
0.58%). Each revolving advance may have a term of up to six months, and this
facility expires February 6, 1999.
 
  Short-term notes represent borrowings by SWEB from banks which have
maturities of 90 days or less from March 31, 1996. Amounts outstanding include
(Pounds)120 million from committed loan facilities and (Pounds)12 million from
uncommitted loan facilities. Interest rates on outstanding borrowings were
between 6.06% and 6.19% at March 31, 1996.
 
  In lieu of cash payments to former shareholders of SWEB for their shares,
the Company offered loan notes at the time of acquisition; the notes are
redeemable at the option of the note holders between June 30, 1996 and
December 31, 2002. Accordingly, these notes are classified as current
liabilities in the accompanying balance sheet.

          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  During the period, the Company extinguished certain debt due to the UK
government, resulting in an extraordinary gain of (Pounds)6 million ($9
million), net of taxes of (Pounds)3 million ($5 million). Also on October 6,
1995, the Company issued (Pounds)597 million ($927 million) of Secured
Floating Rate Bonds to finance the acquisition of SWEB which were redeemed on
February 8, 1996.
 
11. SALE OF INVESTMENTS
   
  The Company's long-term investments accounted for under the cost method
consist of its 7.69% ownership of Teesside (Note 4), the fair value of which
is not readily determinable. The Company's short-term investments are
classified as available-for-sale under SFAS No. 115, the fair value of which
approximated cost at March 31, 1996.     
 
  On December 11, 1995, the Company and the other eleven RECs which jointly
owned The National Grid Holding plc ("NGH") sold their shares of NGH in a
public offering on the London Stock Exchange. The Company received proceeds
relating to the sale of its shares of (Pounds)201 million ($312 million),
which resulted in a pretax gain of (Pounds)14 million ($22 million).
 
  The offering of NGH was conditional on the prior demerger of NGH's Pumped
Storage Business ("PSB") which was completed in November 1995. The Company's
estimated share of the proceeds from the sale of the PSB on December 21, 1995
was (Pounds)39 million ($61 million). No gain or loss was recognized on this
sale.
 
12. STOCKHOLDER'S EQUITY
 
  As discussed in Note 7, the Company obtained effective control of SWEB on
September 18, 1995. During October 1995, (Pounds)315 million ($489 million) of
advances from the parent of the Company were converted to share capital, an
equity contribution of (Pounds)185 million ($287 million) was received from
the parent of the Company, and a combination of short-term and long-term debt
financing was obtained to facilitate the payment of the former shareholders.
These transactions are reflected in the accompanying consolidated statements
of changes in stockholder's equity and cash flows.
 
  Dividends in the amount of (Pounds)191 million ($297 million) were declared
and paid by the Company during the period ending March 31, 1996 as proceeds
from the sale of the Company's shares in NGH (Note 11) provided cash in
addition to that provided from operations during the period.
 
13. SUBSEQUENT EVENT
 
  On July 1, 1996, PP&L Resources, Inc. indirectly purchased a 25% share of
the Company's parent, Southern Investments UK Holdings Limited, for
(Pounds)121.5 million ($189 million).

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 General
 
  South Western Electricity plc ("SWEB") is one of the twelve regional
electricity companies ("RECs") in England and Wales licensed to supply,
distribute, and, to a limited extent, generate electricity. The RECs were
created as a result of the privatization of the UK electricity industry in
1990 after the state owned low voltage distribution networks were allocated to
the then existing twelve regional boards. SWEB's main business, the
distribution and supply of electricity to customers in the southwest of
England, is regulated under the terms of SWEB's Public Electricity Supply
license by the Office of Electricity Regulation ("OFFER").
   
  SWEB operates primarily in its Franchise Area in southwest England. SWEB's
Franchise Area covers approximately 5,560 square miles running from Bristol
and Bath in the northeast, 188 miles southwest along the peninsular to Land's
End and 28 miles beyond to the Isles of Scilly, and has a resident population
of approximately 2.8 million.     
 
 Basis of Presentation
   
  The financial statements of the Company are presented in pounds sterling
((Pounds)) and in conformity with accounting principles generally accepted in
the United States. The accompanying financial statements have not been
prepared in accordance with the policies of Statement of Financial Accounting
Standards No. 71, "Accounting for the Effects of Certain Types of Regulation"
("SFAS No. 71"). This pronouncement, under which most U.S. electric utilities
report financial statements, applies to entities which are subject to cost-
based rate regulation. By contrast, SWEB is not subject to rate regulation,
but, rather, is subject to price cap regulation (Note 4) and therefore the
provisions of SFAS No. 71 do not apply. Financial statements presented in
accordance with SFAS No. 71 contain deferred items which have not yet been
included in rates charged to customers in compliance with the respective
regulatory authorities, but which would have been included in the income
statement of enterprises in general under U.S. GAAP. The accompanying
financial statements of the Company do not contain such deferrals.     
 
  The consolidated financial statements include the accounts of the Company
and its wholly-owned and majority-owned subsidiaries and have been prepared
from records maintained by SWEB in the United Kingdom. All significant
intercompany accounts and transactions have been eliminated in consolidation.
Investments in companies in which the Company's ownership interests range from
20% to 50% and the Company exercises significant influence over operating and
financial policies are accounted for using the equity method. Other
investments are accounted for using the cost method. Dividends received from
investments accounted for under the cost method were (Pounds)9 million for the
year ended 1994, (Pounds)12 million for the year ended 1995, and nil for the
period from April 1, 1995 to September 17, 1995.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and reported amounts of revenues and expenses during the reporting
period. Actual results could differ from those estimates.
 
 Revenue Recognition
 
  SWEB records revenue net of value added tax ("VAT") and accrues revenues for
services provided but unbilled at the end of each reporting period. SWEB
purchases power primarily from a market for the bulk trading of electricity
(the "Pool").

                SOUTH WESTERN ELECTRICITY PLC AND SUBSIDIARIES
                             (PREDECESSOR COMPANY)
 
          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  The Company has a diversified base of customers. No single customer or
industry comprises 10% or more of revenues.
 
 Cash and Cash Equivalents
 
  The Company considers all short-term investments with an original maturity
of three months or less to be cash equivalents.
 
 Property, Plant, and Equipment
 
  Property, plant, and equipment are recorded at original cost which includes
materials, labor, appropriate administrative and general costs, and the
estimated cost of funds used during construction. The cost of maintenance,
repairs, and replacement of minor items of property is charged to maintenance
expense.
   
  Depreciation of the recorded cost of depreciable property, plant, and
equipment is provided by using composite straight-line rates, except for
distribution network assets which are charged at 3% for 20 years and 2% for
the remaining 20 years (Note 9), which are approximately 4.2% per year (2.8%
per year for depreciable utility plant in service).     
 
 Information Technology Consultancy and Development Costs
 
  Information technology consultancy and development costs are expensed when
incurred.
 
 Investments
   
  The Company accounts for its current investments in accordance with
Statement of Financial Accounting Standard ("SFAS") No. 115, "Accounting for
Investments for Certain Debt and Equity Securities." These investments
represent investments in debt securities, which management classifies as
available-for-sale securities in accordance with SFAS No. 115, the fair value
of which approximates cost. The Company's long-term investments are accounted
for using the cost-method and consist of its 7.69% ownership of Teesside (Note
5) the fair value of which is not readily determinable.     
 
 Income Taxes
 
  SFAS No. 109, "Accounting for Income Taxes," requires the asset and
liability approach for financial accounting and reporting for deferred income
taxes. The Company uses the liability method of accounting for deferred income
taxes and provides deferred income taxes for all significant income tax
temporary differences.
 
 Unearned Revenue
 
  Unearned revenue primarily represents the liability for payments received
from customers in connection with the assessment of a VAT on electricity
sales, which was imposed by the UK government effective April 1, 1994 to
include electricity sales to residential customers. As part of the adoption of
the tax, customers were allowed to prepay their electricity bills and avoid
the VAT on the element of the future electricity consumption which was
prepaid. Revenues are recognized as electricity is supplied to these
customers.
 
  Price regulation permits the Company to bill for all estimated allowed
revenue, while actual allowed revenue is not known until after the end of the
fiscal year. When billings exceed the actual allowed revenue, revenues are
deferred on the excess amounts. The deferred amount is deducted from revenues
and included in current liabilities. When billings are less than the allowed
revenue, no anticipation of any potential future recovery is made.

          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
 Financial Instruments
 
  The Company uses financial instruments primarily to mitigate the risk of
exposure to volatility in electricity prices. Such instruments are accounted
for as hedges, and accordingly, gains and losses are deferred and recognized
over the same period as the item hedged (Note 8).
 
  The Company's carrying amount of financial instruments at March 31, 1995 was
zero (Note 8).
 
2. RETIREMENT BENEFITS
 
 Pension Plans
 
  The Company operates two schemes, one based on defined contributions and a
second based on defined benefits.
 
 Defined Contribution
 
  The defined contribution plan was established in the year ended March 31,
1994. The assets of the defined contribution plan are held and administered by
an independent trustee. Contributions to the defined plan were not material
for any period presented.
 
 Defined Benefit
 
  SWEB participates in the Electricity Supply Pension Scheme, which provides
pension and other related defined benefits, based on final pensionable pay, to
substantially all employees throughout the Electricity Supply Industry in the
United Kingdom. Contributions to the plan by SWEB on behalf of its employees
were (Pounds)9.6 million for the period ended March 31, 1994, (Pounds)9.8
million for March 31, 1995, and (Pounds)3.7 million for the period from April
1, 1995 to September 17, 1995.
 
  SWEB uses the "entry age normal method with a frozen initial liability"
actuarial method for funding purposes. Amounts funded to the pension are
primarily invested in equity and fixed income securities.
 
  It was not feasible to adopt SFAS No. 87 on the effective date of the
standard. Accordingly, the unrecognized net transition asset at the date of
initial application of SFAS No. 87, April 1, 1993, is being amortized over 15
years, beginning April 1, 1989, in accordance with the interpretations of the
staff of the Securities and Exchange Commission. The amount of the
unrecognized net transition asset credited to equity on April 1, 1993 was
(Pounds)12.9 million.
 
  The following table shows the actuarial results and assumptions for pension
benefits in respect of SWEB's share of the scheme, as computed under SFAS No.

3. EMPLOYEE INCENTIVE PLANS
   
  South Western Electricity plc had established incentive compensation plans
under which it was authorized to grant incentive stock options in its common
shares. There were two plans in operation.     
   
  The Sharesave Plan, which qualifies as a noncompensatory plan under APB
Opinion No. 25, was open to all eligible employees at the date of grant on
December 11, 1990 at a price of (Pounds)1.75. The options were exercisable in
1996 or at an earlier date if the employee retired or if the Company was
subject to acquisition (see Note 13). The activity in this plan was:

4. REGULATORY MATTERS
 
  OFFER controls the revenues generated by SWEB in its distribution and supply
businesses by applying a price control formula, P + RPI - X, where P is the
price level at the beginning of each new regulatory period, RPI is the change
in the Retail Price Index (inflation) and X is an adjustment factor determined
by OFFER. For the year ended March 31, 1994, X was -2.25% for distribution and
0.0% for supply. For the year ended March 31, 1995, X was -2.25% for
distribution and 2.0% for supply, and for the period April 1, 1995 to
September 17, 1995, X was 3.0% for distribution and 2.0% for supply.
   
  In the distribution business, the Distribution Price Control Formula
("DPCR") is usually set for a five-year period, subject to more frequent
adjustments as determined necessary by the Director General of Electricity
Supply (the "Regulator"). At each review, the Regulator can require a one-time
price reduction. An initial review by the Regulator of allowable income in the
distribution business led to a reduction of the price level by 14% for SWEB
for the twelve months starting April 1, 1995, followed by efficiency factors
of X= 2.0% for each year until March 2000. On July 6, 1995, the Regulator
announced the result of a further distribution price review which was
precipitated by certain market events in the UK electric utility industry. For
SWEB, such announcement meant a further real reduction of 11% in allowable
distribution income for the 12 months starting from April 1, 1996 followed by
an efficiency factor of X= 3.0% for each year until March 31, 2000.     
   
  In the supply business, which is progressively being opened to competition,
price regulation still applies to the market for customers with a demand of up
to 100kW. The calculation of the maximum supply charge is based on a Supply
Price Control Formula, similar to the DPCR and is set for a four-year period.
In 1993, OFFER announced the supply franchise market (customers with demand of
not more than 100 kW) income entitlement for the four-year period ending March
1998. A relatively small efficiency factor of X= 2.0% was applied to SWEB and
is being offset by an allowance for both unit and customer growth. The
nonfranchise markets above 1MW were opened to full competition during
privatization in 1990; the nonfranchise markets above 100kW were opened to
full competition starting in April 1994.     
 
5. COMMITMENTS AND CONTINGENT MATTERS
 
 Power Purchase Agreements
 
  SWEB has entered into a contract relating to the purchase of 200 megawatts

          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  The Company has additional contracts with unaffiliated parties relating to
the purchase of electricity, which expire by March 31, 1998, and contracts
relating to the purchase of gas which expire by September 30, 1998, the terms
of which are immaterial with respect to quantity and price, both annually and
in the aggregate.

 Labor Subject to Collective Bargaining Agreements
 
  Substantially all of SWEB's employees are subject to one of five collective
bargaining agreements. Such agreements are ongoing in nature, and SWEB's
employee participation level is consistent with that of the electric utility
industry in the Great Britain.
 
 
6. SEGMENT REPORTING
 
  The Company is primarily engaged in two electric industry segments:
distribution, which involves the transmission of electricity across its
network and its transfer and delivery to its customers, and supply, which
involves bulk purchase of electricity from the Pool and arranging for its sale
and transfer to its customers. Intersegment sales primarily represent sales
from distribution to supply for the use of the distribution networks.
Information about the Company's operations in these individual segments during
the years ended March 31, 1994 and 1995, and for the period from April 1, 1995
through September 17, 1995 and as of those respective period ends is detailed
below (in millions):

8. FINANCIAL INSTRUMENTS
   
  SWEB utilizes contracts for differences ("CFDs") to mitigate its exposure to
volatility in the prices of electricity purchased through the Pool. Such
contracts allow the Company to effectively convert the majority of its
anticipated Pool purchases from market prices to fixed prices. CFDs are in
place to hedge a portion of electricity purchases on approximately 39,100 GWh
through the year 2008. Accordingly, the gains and losses on such contracts are
deferred and recognized as electricity is purchased. It is not possible to
estimate the fair value of these contracts at present as the contract prices
are based on future events, the effects of which currently are not estimable.
CFDs have been entered into with UK Power Generators.     
 
  The Company is exposed to losses in the event of nonperformance by
counterparties to its CFDs. To manage this credit risk, the Company selects
counterparties based on their credit ratings, limits its exposure to any one
counterparty under defined guidelines, and monitors the market position of the
programs and its relative market position with each counterparty.

  On October 22, 1990, the Predecessor Company issued (Pounds)80 million
12.365% bonds to HM Government which were due for repayment at par in 2008.

million at March 31, 1995.     
   
  Consortium tax creditor represents the benefit of losses surrendered from
consortia in which the Company has invested, which are required to be repaid
at a later date depending on when such consortia have UK taxable income.     
 
  The carrying value of the remaining debt instruments approximate fair value.
No interest is payable on debts other than the (Pounds)80 million HM
Government bonds.
 
11. STOCKHOLDERS' EQUITY
 
  Under the authority of a special resolution passed at the 1994 Annual
General Meeting, the Company purchased 12.3 million of its own shares during

State, was redeemed at par on March 30, 1995 in accordance with the Company's
Articles of Association.

distributable.
 
12. DISCONTINUED OPERATIONS
 
  On June 5, 1995, the Company sold its electrical retailing business for

13. SUBSEQUENT EVENTS

                            NOTES TO THE UNAUDITED
 
                  CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
1. BASIS OF PRESENTATION
 
  The accompanying condensed consolidated financial statements are unaudited
and have been prepared by the management of Southern Investments UK plc (the
"Company") in accordance with the rules and regulations of the Securities and
Exchange Commission. Accordingly, certain information and footnote disclosures
usually found in financial statements prepared in accordance with generally
accepted accounting principles have been condensed or omitted. In the opinion
of the management of the Company, all adjustments (consisting of only normal
recurring adjustments) considered necessary for fair presentation of the
condensed consolidated financial statements have been included, and the
accompanying condensed consolidated financial statements present fairly the
financial position and the results of operations for the interim periods
presented. The condensed consolidated financial statements should be read in
conjunction with the consolidated financial statements included elsewhere in
this prospectus.
 
  The financial statements as of June 30, 1996 are presented in pounds
sterling ("(Pounds)") and in U.S. dollars ("$ or U.S. $"), solely for the
convenience of the reader, at the exchange rate of (Pounds)1 = U.S. $1.5529,
the noon buying rate in New York City for cable transfers in pounds sterling
as certified for customs purposes by the Federal Reserve Bank of New York on
June 28, 1996. No representation is made that the pounds sterling amounts have
been, could have been, or could be converted into U.S. dollars at that or any
other rate of exchange.
 
2. COMPARABILITY OF PERIODS
 
  The condensed financial information included herein shows the results of the
Successor Company for the three months ended June 30, 1996 and those of the
Predecessor Company for the three months ended June 30, 1995. The results for
both periods have been prepared under US GAAP.
 
  As a result of the acquisition, the basis of accounting for the Successor
Company differs from that for the Predecessor Company. The condensed
consolidated financial statements of the Predecessor Company are presented on
a historical cost basis while the consolidated financial statements of the
Successor Company reflect the acquisition under the purchase method of
accounting. Under the purchase method of accounting, fair value was assigned
to the assets and liabilities of SWEB at the date the Company acquired
effective control of SWEB. Goodwill was created to the extent the purchase
price exceeded the difference between the fair value of SWEB's assets and the
fair value of its liabilities.
 
  The recorded assets and liabilities of SWEB immediately prior to the time
the Company gained effective control of SWEB were (Pounds)855 million ($1.328
billion) and (Pounds)515 million ($800 million), respectively. As a result of
the purchase method of accounting, the amount of SWEB's assets recorded on the
books of the Company was increased by (Pounds)910 million ($1.413 billion) to
their fair value of (Pounds)1.765 billion ($2.741 billion), and the amount of
SWEB's liabilities recorded on the books of the Company was increased by
(Pounds)362 million ($562 million) to their fair value of (Pounds)877 million
($1.362 billion). The increase in liabilities included the establishment of
reserves totaling (Pounds)44 million ($68 million) related to staff reductions
and the disposition of ancillary businesses. The resulting difference between
the purchase price of (Pounds)1.063 billion ($1.651 billion) and the
difference between the fair value of the assets acquired and the fair value of
the liabilities assumed as well as the reserves established resulted in
goodwill of (Pounds)175 million ($272 million).
 
3. COMMITMENTS AND CONTINGENT MATTERS
 
 Power Purchase Agreements
 
  SWEB has entered into a contract relating to the purchase of 200 megawatts
of capacity from a 7.69%-owned related party, Teesside Power Limited
("Teesside"), for a period of 15 years beginning April 1, 1993.

                            NOTES TO THE UNAUDITED
 
           CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
The contract with Teesside involves purchases which were above market rates at
the acquisition date. Accordingly, the Company recognized a (Pounds)60 million
($93 million) accrual at the acquisition date for the cost of this contract.
 
  The Company has additional contracts with unaffiliated parties relating to
the purchase of electricity, which expire by March 31, 1998, and contracts
relating to the purchase of gas which expire by September 30, 1998, the terms
of which are immaterial with respect to quantity and price, both annually and
in the aggregate.
 
 Operating Leases
 
  SWEB has commitments under operating leases with various terms and
expiration dates. Expenses associated with these commitments totaled (Pounds)3
million ($5 million) for the period from September 18, 1995 to March 31, 1996.
At March 31, 1996, estimated minimum rental commitments for noncancelable
operating leases were as follows (in millions):

 Labor Subject to Collective Bargaining Agreements
 
  Substantially all of SWEB's employees are subject to one of five collective
bargaining agreements. Such agreements are ongoing in nature, and SWEB's
employee participation level is consistent with that of the electric utility
industry in Great Britain.

for the period from inception (June 23, 1995) to March 31, 1996 and of South

    1995. It has been provided using composite straight line rates which
    approximate 3.1% on an asset value of (Pounds)1,190 million for 170 days,
    less depreciation already charged to the Predecessor Company's
    consolidated statement of income.     
(2) Amortization of goodwill recorded in connection with the purchase business
    combination as if the combination had occurred on April 1, 1995.
   
(3) Reflect the fair value of long-term debt obligations and associated
    interest expense recorded in connection with the purchase business
    combination as if the combination had occurred on April 1, 1995. The
    charge relates to notional interest ((Pounds)2 million) on the discounted
    provision in respect of Teesside, partly offset by a reduction in interest
    to market rates on the HM debt ((Pounds)1 million).     
   
(4) Reflect the interest expense recorded in connection with the purchase
    business combination as if the combination had occurred on April 1, 1995
    and had been 100% financed with short-term borrowings at an interest rate
    of 6% per year. The impact of a 1/8% change in the assumed interest rate
    would change income from continuing operations by (Pounds)0.4 million.
           
(5) Remove gain on the sale of investment in NGG and costs incurred by the
    Predecessor Company relating to bid defense associated with the
    Acquisition.     
   
  The unaudited pro forma consolidated statement of income information above
does not give effect to the bonds issued in the Offering as the interest rate
on such bonds cannot be estimated by the Company prior to pricing such debt.
Refer to "Use of Proceeds" and "Capitalization" on page 19 of this
Registration Statement for further information regarding the impact of the
Offering on the debt of the Company.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Under UK law there is a general rule that any provision (whether contained
in a company's articles or in any other arrangement with the company)
exempting an officer of the company from, or indemnifying him against, any
liability for negligence or other breach of duty in relation to the company is
void (this would include liability for fraud or dishonesty). As an exception
to this rule, a company may indemnify an officer against a liability incurred
by him in defending any proceedings in which judgment is given in his favor or
in which he is acquitted. A company may also give an indemnity where, in any
proceedings against a director, the court relieves him from liability for
negligence or breach of duty where he has acted honestly and reasonably and
ought fairly to be excused from liability. An indemnity is permitted where a
director acts within his powers and is not guilty of negligence or other
breach of duty. A company is also permitted to purchase insurance against any
such liability.
 
  Southern has an insurance policy covering the liabilities and expenses of
Southern and its direct and indirect subsidiaries which might arise in
connection with their lawful indemnification of their directors and officers
for certain of their liabilities and expenses and also covering their officers
and directors against certain other liabilities and expenses.
 
  The Bylaws of Southern Electric provide that no present or future director
or officer of Southern Electric shall be liable for any act, omission, step,
or conduct taken or had in good faith, which is required, authorized, or
approved by any order or orders issued pursuant to the Public Utility Holding
Company Act of 1935, the Federal Power Act, or any federal or state statute or
municipal ordinance regulating Southern Electric or its parent by reason of
their being holding or investment companies, public utility companies, public
utility holding companies, or subsidiaries of public utility holding
companies. In the event that the foregoing provisions are found not to
constitute a valid defense on the grounds of not being applicable to the
particular class of plaintiff, each such director and officer is required to
be reimbursed under such Bylaws for, or indemnified against, all expenses and
liabilities incurred by him or imposed on him, in connection with, or arising
out of, any such action, suit, or proceeding based on any act, omission, step,
or conduct taken or had in good faith as in such provisions described.
 
                                     II-1
<PAGE>
 
  The Bylaws of Southern Electric further provide that each person who is or
was a director of Southern Electric or officer or employee of Southern
Electric holding one or more positions of management through and inclusive of
Project managers and Business Development Managers (but not positions below
the level of such managers) (such positions being hereinafter referred to as
"Management Positions") and who was or is a party or was or is threatened to
be made a party to any threatened, pending or completed claim, action, suit or
proceeding, whether civil, criminal, administrative or investigative, by
reason of the fact that he is or was serving at the request of Southern
Electric as a director, alternate director, officer, employee, agent or
trustee of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise, shall be indemnified by Southern Electric as
a matter of right against any and all expenses (including attorneys' fees)
actually and reasonably incurred by him and against any and all claims,
judgments, fines, penalties, liabilities and amounts paid in settlement
actually incurred by him in defense of such claim, action, suit or proceeding,
including appeals, to the full extent permitted by applicable law. Expenses
(including attorneys' fees) incurred by a director of Southern Electric or
officer or employee of Southern Electric holding one or more Management
Positions with respect to the defense of any such claim, action, suit or
proceeding may be advanced by Southern Electric prior to the final disposition
of such claim, action, suit or proceeding, as authorized by the board of
directors in the specific case, upon receipt of an undertaking by or on behalf
of such person to repay such amount unless it shall ultimately be determined
that such person is entitled to be indemnified by Southern Electric under such
provisions or otherwise.
 
  The Articles of Association of the Company provide that, without prejudice
to the provisions of Regulation 118 of Table A of the Companies Acts 1985 to
1989 under UK law, the directors shall have power to purchase and maintain
insurance for or for the benefit of any persons who are or were at any time
directors, officers, or employees or auditors of the Company, or of any other
company which is its holding company or parent undertaking or in which the
Company or such holding company or parent undertaking or any of the
predecessors of the Company or of such holding company or parent undertaking
has any interest whether direct or indirect or which is in any way allied to
or associated with the Company, or of any subsidiary undertaking of the
Company or of any such other company, or who are or were at any time trustees
of any pension fund in which any employees of the Company or of any such other
company or subsidiary undertaking are interested, including (without prejudice
to the generality of the foregoing) insurance against any liability incurred
by such persons in respect of any act or omission in the actual or purported
execution and/or discharge of their duties and/or in the exercise or purported
exercise of their powers and/or otherwise in relation to their duties, powers
or offices in relation to the Company or any such other company, subsidiary
undertaking or pension fund. For the purposes of this Regulation "holding
company" "parent undertaking" and "subsidiary undertaking" shall have the same
meanings as in the Companies Acts 1985 to 1989.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
  Upon its incorporation on June 23, 1995, the Company issued two ordinary
shares at (Pounds)1 each to its two corporate incorporators, both of which
were incorporated in England and Wales. On July 4, 1995 the Company issued
49,998 ordinary shares at an aggregate price of (Pounds)49,998 to Holdings,
formerly Premier American Investments plc, at which time Holdings also
acquired the 2 shares held by the incorporators. On October 6, 1995 the
Company issued to Holdings an additional 500,350,587 ordinary shares at an
aggregate price of (Pounds)500,350,587, one of which is held by a UK resident
individual as nominee for Holdings.
 
  During the period July 13, 1995 to August 24, 1995 the Company issued a
series of bonds underwritten by Swiss Bank Corporation (acting through its
division, SBC Warburg), Chemical Investment Bank Limited, IBJ International
plc, National Westminster Bank plc and The Toronto-Dominion Bank with an
aggregate offering price of (Pounds)627,070,000 and underwriting discounts and
commissions in the amount of (Pounds)6,270,700.
 
  All such issuances and sales were exempt from registration requirements of
the Securities Act, by reason of the fact that such securities were offered
and sold outside the United States to persons who were not citizens of the
United States or in transactions which were exempt from registration pursuant
to Regulation S of the Securities Act.

   And for the Period From Inception (June 23, 1995) to March 31, 1996     
 
 
ITEM 17. UNDERTAKINGS
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted as to directors, officers, and controlling persons of the
Registrant pursuant to the provisions described in Item 14 or otherwise, the
Registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer, or controlling
person of the Registrant in the successful defense of any action, suit, or
proceeding) is asserted by such director, officer, or controlling person in
connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
 
  The undersigned Registrant undertakes that: (1) for purposes of determining
any liability under the Securities Act, the information omitted from the form
of prospectus as filed as part of the registration statement in reliance upon
Rule 430A and contained in the form of prospectus filed by the Registrant
pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be
deemed to be part of the registration statement as of the time it was declared
effective, and (2) for the purpose of determining any liability under the
Securities Act, each post-effective amendment that contains a form of
prospectus shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

            REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS AS TO SCHEDULE
 
To the Board of Directors of Southern Investments UK plc:
   
We have audited in accordance with generally accepted auditing standards, the
financial statements of SOUTHERN INVESTMENTS UK PLC AND SUBSIDIARIES
(Successor Company) included in this registration statement and have issued
our report thereon dated July 25, 1996. Our audit was made for the purpose of
forming an opinion on the basic financial statements taken as a whole. The
schedule listed in Item 16(b) is the responsibility of the company's
management and is presented for purposes of complying with the Securities and
Exchange Commission's rules and is not part of the basic financial statements.
The schedule has been subjected to the auditing procedures applied in the
audit of the basic financial statements and, in our opinion, fairly states in
all material respects the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.

                    Southern Investments UK plc, a public limited liability
          company incorporated under the Companies Act 1985 in England and Wales
          (the "Company"), proposes, subject to the terms and conditions stated

          execution of this Agreement.  If it is contemplated, at the time this

          Sheet means the date of such Term Sheet.  The term "Preliminary
          Prospectus" as used in this Agreement means the prospectus subject to
          completion in the form included in the registration statement at the

                    3.  Offering by the Underwriters:  The Company has been
          advised by you that the Underwriters propose to make a public offering

          of [_________________] (or at such other place as may be agreed upon
          by you and the Company), upon the delivery of the Senior Notes to you

          Underwriters in denominations selected by the Company.  If you shall
          request that any of the Senior Notes be registered in a name or names
          other than that of the Underwriter agreeing to purchase such Senior
          Notes, such Underwriter shall pay any transfer taxes resulting from
          such

          make initial delivery of the Senior Notes in temporary form, such
          Senior Notes will be exchangeable at said office of the Trustee, upon
          request, for definitive fully registered Senior Notes of authorized
          denominations without charge to the holders thereof as soon as is
          reasonably practicable.

                    3.

                         (4) Opinion of Sewerd & Kissel, of New York, New York,
                    substantially in the form attached hereto as Exhibit 4.

                         (5) Letters dated the date hereof from Arthur Andersen
                    LLP and Ernst & Young, substantially in the forms attached
                    hereto as Exhibit 5 and Exhibit 6, respectively, and a

                    (c)  That no amendment or supplement to the registration
               statement or prospectus filed subsequent to the time this
               agreement becomes effective shall be unsatisfactory in form to
               the Underwriters or shall contain information (other than with
               respect to an amendment or supplement relating solely to the
               activity of any Underwriter or Underwriters) which, in your
               reasonable judgment, shall materially impair the marketability of
               the Senior Notes.

                    (d)  That, prior to the time of purchase, no stop order with
               respect to the effectiveness of the Registration Statement shall
               have been issued under the Act by the Commission or proceedings
               therefor initiated or threatened.

                    (e)  That, prior to the time of purchase, there shall have
               been no material adverse change in the business, properties or
               financial condition of the Company from that set forth in or
               contemplated by the Prospectus, and that the Company shall, at
               the time of purchase, have delivered to you a certificate to such
               effect of an executive officer of the Company.  For the purposes
               of this condition, the sale by the Company of, or its failure to
               sell, any issue of other securities shall not be deemed to be
               such a change.

                    (f)  That the Company shall have performed such of its
               obligations under this Agreement as are to be performed at or
               prior to the time of purchase by the terms hereof.

               6.  Certain Covenants of the Company:  In further consideration
          of the agreements of the Underwriters herein contained, the Company
          covenants as follows:

                    (a)  If the Registration Statement has been declared
               effective prior to the execution and delivery of this Agreement,
               the Company will file with the Commission (i) if the Company
               relies on Rule 434 under the Act, a Term Sheet relating to the
               Senior Notes, that identifies the Preliminary Prospectus that it
               supplements and contains such information as is required or
               permitted by Rules 434, 430A and 424(b) under the Act or (2) if
               the Company does not rely on Rule 434 under the Act, a prospectus
               in the form most recently included in an amendment to such
               registration statement (or, if no such amendment shall have been
               filed, in such registration statement) with such changes or
               insertions as are required or by Rule 430A or permitted by Rule
               424(b) under the Act.  The Company will advise you promptly of
               any such filing pursuant to Rule 424(b).

                    (b)  As soon as the Company is advised thereof, to advise
               you and confirm the advice in writing of any request made by the
               Commission for amendments to the Registration Statement or
               Prospectus, or of the issue of a stop order suspending the
               effectiveness of the Registration Statement or of the initiation
               or threat of any proceedings for that purpose and, if such a stop
               order should be issued by the Commission, to make every
               reasonable effort to obtain the lifting or removal thereof as
               soon as possible.

                    (c)  To deliver to the Underwriters, without charge during
               such period of time (not exceeding nine months after this
               agreement becomes effective) as the Underwriters are required by
               law to deliver a prospectus, as many copies of the Preliminary
               Prospectus and the Prospectus (as supplemented or amended if the
               Company shall have made any supplements or amendments thereto) as
               you may reasonably request; and, in

                                       4
<PAGE>
 
               case any Underwriter is required by law to deliver a prospectus
               after the expiration of nine months after the date this agreement
               becomes effective, to furnish to such Underwriter, upon your
               request, at the expense of such Underwriter, a reasonable
               quantity of a supplemental prospectus or of supplements to the
               Prospectus complying with Section 10(a)(3) of the Securities Act.

                    (d)  During such period of time after the date this
               agreement becomes effective as the Underwriters are required by
               law to deliver a prospectus, to file timely all documents
               required to be filed with the Commission pursuant to Section 13
               or 14 of the Exchange Act.

                    (e)  To furnish to you one manually signed copy of the
               Registration Statement as initially filed with the Commission and
               all amendments thereto (in each case, exclusive of exhibits), and
               to furnish to you sufficient plain copies of said registration
               statement and all amendments thereto (exclusive of exhibits) for
               distribution of two each, and all said documents incorporated
               therein as of the time of purchase (exclusive of exhibits) for
               distribution of one each, to the other Underwriters.

                    (f)  For such period of time (not exceeding nine months)
               after the date this agreement becomes effective as they are
               required by law to deliver a prospectus, if any event shall have
               occurred as a result of which it is necessary to amend or
               supplement the Prospectus in order to make the statements
               therein, in light of the circumstances when the Prospectus is
               delivered to a purchaser, not misleading, forthwith to amend or
               supplement the Prospectus by preparing and furnishing, at its own
               expense, to the Underwriters and to dealers (whose names and
               addresses are furnished to the Company by you) to whom Senior
               Notes may have been sold by you on behalf of the Underwriters
               and, upon request, to any other dealers making such request,
               either amendments to the Prospectus or supplements thereto so
               that the statements in the Prospectus as so amended or
               supplemented will not, in the light of the circumstances when the
               Prospectus is delivered to a purchaser, be misleading.

                    (g)  To make generally available to the Company's security
               holders, as soon as practicable, an earning statement (which need
               not be audited) covering a period of at least twelve months
               beginning with the first day of the month immediately following
               the effective date of the Registration Statement as defined in
               Rule 158(c) under the Securities Act, which earning statement
               shall satisfy the provisions of Section 11(a) of the Securities
               Act.

                    (h)  To cooperate with the Underwriters to qualify the
               Senior Notes for offer and sale under the securities or blue sky
               laws of such United States jurisdictions as you may reasonably
               request and to pay filing fees, reasonable attorneys' fees and
               disbursements in connection therewith in an amount not exceeding
               $15,000 in the aggregate (including filing fees and disbursements
               paid or incurred prior to the date this agreement becomes
               effective), provided, however, that the Company shall not be

                                       5
<PAGE>
 
               required to qualify as a foreign corporation or to file a consent
               to service of process or to file annual reports or to comply with
               any other requirements deemed by the Company to be unduly
               burdensome.

                    (i)  To pay expenses, fees and taxes (other than transfer
               taxes) in connection with (1) the preparation and filing of the
               Registration Statement, Preliminary Prospectus and Prospectus,
               (2) the preparation, execution, filing and recording of the
               indenture pursuant to which the Senior Notes are to be issued,
               (3) the issue and delivery of the Senior Notes to the
               Underwriters, and (4) the furnishing of the opinions, letter and
               certificates referred to in Section 5 hereof upon the terms and
               in the amounts agreed pursuant to separate agreements; provided,
               however, that the Underwriters shall be solely responsible to pay
               the fees and expenses of counsel to the Underwriters, and the
               Company shall not be liable to reimburse the Underwriters for
               such fees and expenses.

                    (j)  If the Underwriters shall not take up and pay for the
               Senior Notes due to the failure of the Company to comply with any
               of the conditions specified in Section 5 hereof, to reimburse the
               Underwriters for their reasonable out-of-pocket expenses, in an
               amount not exceeding a total of $10,000, incurred in connection
               with the financing contemplated by this Agreement.

               7.  Warranties of and Indemnity by the Company:

                    (a)  The Company warrants and represents to each of the
               Underwriters that:

                         (i)  Each Preliminary Prospectus, when filed with the
                    Commission, conformed in all material respects to the
                    requirements of the Act and the Rules and Regulations; and,
                    when the Registration Statement became or becomes effective
                    and at all times subsequent thereto up to and including the
                    Closing Date, the Registration Statement and the Prospectus
                    and, if any, each amendment and each supplement thereto
                    conformed, or will conform, in all material respects to the
                    requirements of the Act and the Rules and Regulations and
                    the Trust Indenture Act of 1939, as amended (the "Trust
                    Indenture Act"); and none of the Registration Statement, nor
                    any amendment thereto, included or will include any untrue
                    statement of a material fact or omit to state any material
                    fact required to be stated therein or necessary to make the
                    statements therein not misleading; and none of the
                    Prospectus or any Preliminary Prospectus (or any supplement
                    thereto) as of their respective dates included any untrue
                    statement of a material fact or omitted to state any
                    material fact required to be stated therein or necessary to
                    make the statements therein, in light of the circumstances
                    under which they were made, not misleading; provided,
                    however, that the Company makes no warranty or
                    representation to any Underwriter with respect to any
                    statements or omissions made in reliance upon and in
                    conformity with information furnished in writing to the
                    Company by, or through you on behalf


               

                                       6
<PAGE>
 
                    of, any Underwriter for use in the Registration Statement,
                    any Preliminary Prospectus or the Prospectus or any
                    amendment or supplement thereto, or to any statements in or
                    omissions from that part of the Registration Statement that
                    shall constitute the Statement of Eligibility and
                    Qualification under the Trust Indenture Act of 1939, as
                    amended, of the Trustee under the Indenture.

                         (ii)  The consummation of the transactions herein
                    contemplated and the performance by the Company of the terms
                    of this agreement will not violate any of the terms,
                    conditions or provisions of, or constitute a default under,
                    any indenture or other material contract or agreement to
                    which the Company is now a party or the charter or by-laws
                    of the Company or any order of any court or administrative
                    agency entered in any proceedings to which the Company is
                    now a party the violation of which would have a material
                    adverse effect on the Company's ability to pay the principal
                    or interest on the Senior Notes.

                    (b)  The Company agrees to indemnify and hold harmless each
               of the Underwriters and each person, if any, who controls any
               such Underwriter within the meaning of Section 15 of the
               Securities Act against any and all losses, claims, damages or
               liabilities, joint or several, to which they or any of them may
               become subject under the Securities Act or otherwise, and to
               reimburse the Underwriters and such controlling person or
               persons, if any, for any legal or other expenses incurred by them
               in connection with defending any actions, insofar as such losses,
               claims, damages, liabilities or actions arise out of or are based
               upon any untrue statement or alleged untrue statement of a
               material fact contained in a Preliminary Prospectus (if used
               prior to the effective date of the registration statement), or in
               the Registration Statement, or in the Prospectus, in the
               Prospectus as so amended or supplemented (provided that, if such
               Prospectus or such Prospectus as amended or supplemented is used
               after the expiration of the period of time specified in Section
               6(f) hereof, it shall contain such amendments or supplements as
               the Company deems necessary to comply with Section 10(a)(3) of
               the Securities Act), or arise out of or are based upon any
               omission or alleged omission to state therein a material fact
               required to be stated therein or necessary to make the statements
               therein not misleading, except insofar as such losses, claims,
               damages, liabilities or actions arise out of or are based upon
               any such untrue statement or omission or alleged untrue statement
               or omission which was made in such Registration Statement or
               Prospectus in reliance upon and in conformity with information
               furnished in writing to the Company by, or through you on behalf
               of, any Underwriter for use therein and except that this
               indemnity with respect to a Preliminary Prospectus, and with
               respect to the Prospectus if the Company shall have furnished any
               amendment or supplement thereto, shall not inure to the benefit
               of any Underwriter (or of any person controlling such
               Underwriter) on account of any losses, claims, damages,
               liabilities or actions arising from the sale of Senior Notes to
               any person if a copy of the Prospectus, as the same may then be
               amended or supplemented, shall not have been sent or given by or
               on behalf of such Underwriter to such person with or prior to the
               written confirmation of the sale involved.  Each Underwriter
               agrees, within ten days after the receipt by it of notice of the
               commencement of any action in respect of

                                       7
<PAGE>
 
               which indemnity may be sought by it, or by any person controlling
               it, from the Company on account of its agreement contained in
               this Section 7(b), to notify the Company in writing of the
               commencement thereof, but the omission of such Underwriter so to
               notify the Company of any such action shall not release the
               Company from any liability which it may have to such Underwriter
               or to such controlling person otherwise than on account of the
               indemnity agreement contained in this Section 7(b). In case any
               such action shall be brought against any Underwriter or any such
               person controlling such Underwriter and such Underwriter shall
               notify the Company of the commencement thereof, as above
               provided, the Company shall be entitled to participate in (and,
               to the extent that it shall wish, including the selection of
               counsel, to direct) the defense thereof at its own expense. In
               case the Company elects to direct such defense and select such
               counsel, any Underwriter or controlling person shall have the
               right to employ its own counsel, but, in any such case, the fees
               and expenses of such counsel shall be at the expense of such
               Underwriter or controlling person unless the employment of such
               counsel has been authorized in writing by the Company in
               connection with defending such action.

               The Company's indemnity agreement contained in this Section 7(b),
          and its covenants, warranties and representations contained in this
          agreement, shall remain in full force and effect regardless of any
          investigation made by or on behalf of any Underwriter or controlling
          person, and shall survive the delivery of and payment for the Senior
          Notes hereunder.

               8.  Warranties of and Indemnity by Underwriters:

                    (a)  Each Underwriter warrants and represents to the
               Company, its directors and such of its officers as shall have
               signed the Registration Statement, and to each other Underwriter
               that the information furnished in writing to the Company by, or
               through you on behalf of, such Underwriter for use in the
               Registration Statement, any Preliminary Prospectus or the
               Prospectus does not contain an untrue statement of a material
               fact and does not omit to state a material fact in connection
               with such information required to be stated therein or necessary
               to make such information not misleading.

                    (b)  Each Underwriter agrees to indemnify and hold harmless
               the Company, its directors and such of its officers as shall have
               signed the Registration Statement, and each other Underwriter and
               each person, if any, who controls the Company or any such other
               Underwriter within the meaning of Section 15 of the Securities
               Act, to the same extent and upon the same terms as the indemnity
               agreement of the Company set forth in Section 7(b) hereof, but
               only with respect to untrue statements or omissions or alleged
               untrue statements or omissions made in the Registration
               Statement, any Preliminary Prospectus or the Prospectus, or the
               Prospectus as amended or supplemented, in reliance upon and in
               conformity with information furnished in writing to the Company
               by, or through you on behalf of, such Underwriter for use
               therein.

               The indemnity agreement on the part of each Underwriter contained
          in this Section 8(b), and the warranties and representations of such
          Underwriter contained in this Agreement, shall

                                       8
<PAGE>
 
          remain in full force and effect regardless of any investigation made
          by or on behalf of the Company or other Underwriter or controlling
          person, and shall survive the delivery of and payment for the Senior
          Notes hereunder.

               9.  Substitution of Underwriters:  If any Underwriter under this
          Agreement shall fail or refuse (whether for some reason sufficient to
          justify, in accordance with the terms hereof, the termination of its
          obligations to purchase or otherwise) to purchase the principal amount
          of the Senior Notes which it has agreed to purchase, the Company shall
          immediately notify you and you may, within 24 hours of receipt of such
          notice, procure some other responsible party or parties satisfactory
          to the Company, who may include one or more of the remaining
          Underwriters, to purchase or agree to purchase such principal amount
          of the Senior Notes on the terms herein set forth; and, if you shall
          fail to procure a satisfactory party or parties to purchase or agree
          to purchase such principal amount of the Senior Notes on such terms
          within such period after the receipt of such notice, then the Company
          shall be entitled to an additional period of 24 hours within which to
          procure another party or parties to purchase or agree to purchase such
          principal amount of the Senior Notes on the terms herein set forth.
          In any such case, either you or the Company shall have the right to
          postpone the Closing Date for a period not to exceed five full
          business days from the date set forth in Section 4 hereof, in order
          that the necessary changes in the Registration Statement and
          Prospectus and any other documents and arrangements may be effected.
          If you shall fail to procure a satisfactory party or parties to
          purchase or agree to purchase such principal amount of the Senior
          Notes, and if the Company also does not procure another party or
          parties to purchase or agree to purchase such principal amount of the
          Senior Notes, as above provided, then this agreement shall terminate.
          In the event of any such termination, the Company shall not be under
          any liability to any Underwriter (except to the extent, if any,
          provided in Section 6(j) hereof), nor shall any Underwriter (other
          than a Underwriter who shall have failed or refused to purchase Senior
          Notes without some reason sufficient to justify, in accordance with
          the terms hereof, its termination of its obligations hereunder) be
          under any liability to the Company.

               10.  Termination of Agreement:  This Agreement may be terminated
          at any time prior to the time of purchase by you with the consent of
          Underwriters who have agreed to purchase in the aggregate 50% or more
          of the aggregate principal amount of the Senior Notes, if, after this
          agreement becomes effective and prior to the time of purchase, (i)
          trading in securities on the New York Stock Exchange shall have been
          generally suspended, (ii) minimum or maximum ranges for prices shall
          have been generally established on the New York Stock Exchange by the
          Commission or by the New York Stock Exchange, (iii) a general banking
          moratorium shall have been declared by federal or New York State
          authorities or (iv) there shall have occurred any outbreak or
          escalation of major hostilities in which the United States is
          involved, any declaration of war by the United States Congress or any
          other substantial national or international calamity or emergency
          affecting the United States, in any such case provided for in clauses
          (i) through (iv) with the result that, in your reasonable judgment,
          the marketability of the Senior Notes shall have been materially
          impaired.

               If you elect to terminate this Agreement, as provided in this
          Section 10, the Company and

       

                                       9
<PAGE>
 
          each other Underwriter shall be notified promptly by you by telephone,
          confirmed in writing. If this agreement shall not be carried out by
          any Underwriter for any reason permitted hereunder, or if the sale of
          the Senior Notes to the Underwriters as herein contemplated shall not
          be carried out because the Company is not able to comply with the
          terms hereof, the Company shall not be under any obligation under this
          agreement and shall not be liable to any Underwriter or to any member
          of any selling group for the loss of anticipated profits from the
          transactions contemplated by this agreement (except that the Company
          shall remain liable to the extent provided in Section 6(j) hereof) and
          the Underwriters (other than a defaulting Underwriter) shall be under
          no liability to the Company nor be under any liability under this
          agreement to one another.

               11.  Notices:  All notices hereunder shall, unless otherwise
          expressly permitted, be in writing and be delivered at or mailed to
          the following addresses: if to the Underwriters or to you, to you at
          [address], and, if to the Company, to the Company at [address].

               12.  Parties in Interest:  The agreement herein set forth has
          been and is made solely for the benefit of the Underwriters and the
          Company, its directors and such of its officers as shall have signed
          the Registration Statement, and the controlling persons, if any,
          referred to in Sections 7 and 8 hereof, and their respective
          successors, assigns, executors and administrators, and, subject to the
          provisions of Section 9 hereof, no other person shall acquire or have
          any right under or by virtue of this agreement.

               13.  Applicable Law, Jurisdiction.  This Agreement shall be
          governed by and construed in accordance with the laws of the State of
          New York, without giving effect to the choice of law or conflict of
          law principles thereof.  Each party hereto consents to the
          jurisdiction of each court in which any action is commenced seeking
          indemnity pursuant to Section 7 or 8 above and agrees to accept,
          either directly or through an agent, service of process of each such
          court.

               14.  Counterparts.  This Agreement may be executed in any number
          of counterparts, each of which shall be deemed to be an original, and
          all of which together shall be deemed to be one and the same
          instrument.

SECTION 102.  Compliance Certificates and Opinions
              ------------------------------------

          Except as otherwise expressly provided by this Indenture, upon any
application or request by the Company to the Trustee to take any action under
any provision of this Indenture, the Company shall furnish to the Trustee an
Officers' Certificate stating that all conditions precedent, if any, provided
for in this Indenture relating to the proposed action have been complied with

          Every certificate or opinion with respect to compliance with a

certificate or opinion are based;

          (3) a statement that, in the opinion of each such individual, he has

          (4) a statement as to whether, in the opinion of each such individual,
such condition or covenant has been complied with.

SECTION 103.  Form of Documents Delivered to Trustee
              --------------------------------------

          In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

          Any certificate or opinion of an officer or Director of the Company
may be based, insofar as it relates to legal matters, upon a certificate or
opinion of, or representations by, counsel, unless such officer or Director
knows, or in the exercise of reasonable care should 

                                       8
<PAGE>
 
know, that the certificate or opinion or representations with respect to the
matters upon which his certificate or opinion is based are erroneous. Any such
certificate or opinion of Counsel may be based, insofar as it relates to factual
matters, upon a certificate or opinion of, or representations by, an officer or
officers or Director or Directors of the Company stating that the information
with respect to such factual matters is in the possession of the Company, unless
such counsel knows, or in the exercise of reasonable care should know, that the
certificate or opinion or representations with respect to such matters are
erroneous.

          Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

SECTION 104.  Acts of Holders
              ---------------

          (a) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in Person or by agent duly
appointed in writing, and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company.  Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments.  Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 601) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section 103.

          Without limiting the generality of the foregoing, unless otherwise
established in or pursuant to a Board Resolution or set forth or determined in
an Officers' Certificate, or established in one or more indentures supplemental
hereto, pursuant to Section 301, a Holder, including a Book-Entry Depositary
that is a Holder of a Global Security, may make, give or take, by a proxy, or
proxies, duly appointed in writing, any request, demand, authorization,
direction, notice, consent, waiver or other action provided in this Indenture to
be made, given or taken by Holders, and a Book-Entry Depositary that is a Holder
of a Global Security may provide its proxy or proxies to the beneficial owners
of interests in any such Global Security through such Book-Entry Depositary's
standing instructions and customary practices.

          (b) The fact and date of the execution by any Person of any such
instrument, writing or proxy may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument, writing or proxy acknowledged to him the execution thereof.

     Where such execution is by a signer acting in a capacity other than his
individual capacity, such certificate or affidavit shall also constitute
sufficient proof of his authority.  The fact and date of the execution of any
such instrument, writing or proxy, or the authority of the Person executing the
same, may also be proved in any other manner which the Trustee deems sufficient.

          (c) The ownership of Registered Securities shall be proved by the
Security Register.

                                       9
<PAGE>
 
          (d) Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Holder of any Security shall bind every future Holder
of the same Security and the Holder of every Security issued upon the
registration of transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done, omitted or suffered to be done by the Trustee or the
Company in reliance thereon, whether or not notation of such action is made upon
such Security.

          (e) The principal or face amount and serial numbers of Bearer
Securities of any series held by any Person, and the date of holding the same,
may be proved by the production of such Bearer Securities or by a certificate
executed by the Book-Entry Depositary for such Bearer Securities.

          (f) If the Company shall solicit from the Holders of Securities of any
series any request, demand, authorization, direction, notice, consent, waiver or
other Act, the Company may, at its option, by Board Resolution, fix in advance a
record date for purposes of determining the identity of Holders of Securities
entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other Act, but the Company shall have no obligation to do so.
Any such record date shall be fixed at the Company's discretion.  If such a
record date is fixed, such request, demand, authorization, direction, notice,
consent, waiver or other Act may be sought or given before or after the record
date, but only the Holders of Securities of record at the close of business on
such record date shall be deemed to be Holders of Securities for the purpose of
determining whether Holders of the requisite proportion of Securities of such
series Outstanding have authorized or agreed or consented to such request,
demand, authorization, direction, notice, consent, waiver or other Act, and for
that purpose the Securities of such series Outstanding shall be computed as of
such record date.

          With regard to any record date set pursuant to this subsection, the
Holders of Outstanding Securities of the relevant series on such record date (or
their duly appointed agents), and only such Persons, shall be entitled to take
relevant action, whether or not such Holders remain Holders after such record
date.  With regard to any action that may be taken hereunder only by Holders of
a requisite principal amount of Outstanding Securities of any series (or their
duly appointed agents) and for which a record date is set pursuant to this
subsection, the Company may, at its option, set an expiration date after which
no such action purported to be taken by any Holder shall be effective hereunder
unless taken on or prior to such expiration date by Holders of the requisite
principal amount of Outstanding Securities of such series on such record date
(or their duly appointed agents).

     On or prior to any expiration date set pursuant to this subsection, the
Company may, on one or more occasions at its option, extend such expiration date
to any later date.  Nothing in this subsection shall prevent any Holder (or any
duly appointed agent thereof) from taking, at any time, any action contrary to
or different from, any action previously taken, or purported to have been taken,
hereunder by such Holder, in which event the Company may set a record date in
respect thereof pursuant to this subsection.  Notwithstanding the foregoing or
the Trust Indenture Act, the Company shall not set a record date for, and the
provisions of this paragraph shall not apply with respect to, any action to be
taken by Holders pursuant to Section 501, 502 or 512.

          Upon receipt by the Trustee of written notice of any default described
in Section 501, any declaration of acceleration, or any rescission and annulment
of any such declaration, pursuant to Section 502 or of any direction in
accordance with Section 512, a record date shall automatically and without any
other action by any Person be set for the purpose of determining the Holders of
outstanding Securities of the series entitled to join in such notice,
declaration, or 

                                       10
<PAGE>
 
rescission and annulment, or direction, as the case may be, which record date
shall be the close of business on the day the Trustee receives such notice,
declaration, rescission and annulment or direction, as the case may be. The
Holders of Outstanding Securities of such series on such record date (or their
duly appointed agent), and only such Persons, shall be entitled to join in such
notice, declaration, rescission and annulment, or direction, as the case may be,
whether or not such Holders remain Holders after such record date;
provided that, unless such notice, declaration, rescission and annulment, or
- --------
direction, as the case may be, shall have become effective by virtue of Holders
of the requisite principal amount of outstanding Securities of such series on
such record date (or their duly appointed agents) having joined therein on or
prior to the 90th day after such record date, such notice of default,
declaration, or rescission and annulment or direction given or made by the
Holders, as the case may be, shall automatically and without any action by any
Person be canceled and of no further effect. Nothing in this paragraph shall
prevent a Holder (or a duly appointed agent thereof) from giving, before or
after the expiration of such 90-day period, a notice of default, a declaration
of acceleration, a rescission and annulment of a declaration of acceleration or
a direction in accordance with Section 512, contrary to or different from, or,
after the expiration of such period, identical to, a previously given notice,
declaration, rescission and annulment, or direction, as the case may be, that
has been canceled pursuant to the proviso to the preceding sentence, in which
event a new record date in respect thereof shall be set pursuant to this
paragraph.

SECTION 105.  Notices, Etc., to Trustee and Company
              -------------------------------------

          Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with,

          (1) the Trustee by any Holder or by the Company shall be sufficient
     for every purpose hereunder if made, given, furnished or filed in writing
     to or with the Trustee at its Corporate Trust Office, or

          (2) the Company by the Trustee or by any Holder shall be sufficient
     for every purpose hereunder (unless otherwise herein expressly provided) if
     in writing and mailed, first-class postage prepaid, to the Company
     addressed to it at the address of its principal office specified in the
     first paragraph of this instrument or at any other address previously
     furnished in writing to the Trustee by the Company.

SECTION 106.  Notice to Holders; Waiver
              -------------------------

          Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, (i) in the case of a Holder of Registered Securities, at his
address as it appears in the Security Register, and (ii) in the case of a Holder
of Global Bearer Securities, at the address provided in or pursuant to the
relevant Deposit Agreement of the relevant Book-Entry Depositary or Depositaries
therefor, not later than the latest date, and not earlier than the earliest
date, prescribed for the giving of such notice.  In any case where notice to
Holders is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders.

          If, by reason of the suspension of regular mail service or by reason
of any other cause, it shall be impracticable to give such notice by mail, then
such notification as shall be 

                                       11
<PAGE>
 
made at the direction of the Company in a manner reasonably calculated, to the
extent practicable under the circumstances, to provide prompt notice shall
constitute a sufficient notification for every purpose hereunder.

          Except as otherwise expressly provided herein or otherwise specified
with respect to any Securities pursuant to Section 301, where this Indenture
provides for notice to Holders of Bearer Securities of any event and the rules
of any securities exchange on which such Bearer Securities are listed so
require, such notice shall be sufficiently given to Holders of such Bearer
Securities if published in such newspaper or newspapers as may be specified in
such Securities on a Business Day at least twice, the first such publication to
be not earlier than the earliest date, and not later than the latest date,
prescribed for the giving of such notice.  Any such notice by publication shall
be deemed to have been given on the date of the first such publication.  In
addition, notice to the Holder of any Global Bearer Security shall be given by
mail in the manner provided above.

          If by reason of any cause it shall be impracticable to publish any
notice to Holders of Bearer Securities as provided above, then such notification
to Holders of Bearer Securities as shall be given with the approval of the
Trustee shall constitute sufficient notice to such Holders for every purpose
hereunder.  Neither the failure to give notice by publication to Holders of
Bearer Securities as provided above, nor any defect in any notice so published,
shall affect the sufficiency of such notice with respect to other Holders of
Bearer Securities or the sufficiency of any notice to Holders of Registered
Securities given as provided herein.

          Any request, demand, authorization, direction, notice, consent, waiver
or Act required or permitted under this Indenture shall be in the English
language, except that any published notice may be in an official language of the
country of publication.

          Where this Indenture provides for notice in any manner, such notice
may be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice.  Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

SECTION 107.  Conflict with Trust Indenture Act
              ---------------------------------

          If any provision hereof limits, qualifies or conflicts with any
provision of the Trust Indenture Act or another provision which is required or
deemed to be included in this Indenture by any of the provisions of the Trust
Indenture Act, the provision or requirement of the Trust Indenture Act shall
control.  If any provision of this Indenture modifies or excludes any provision
of the Trust Indenture Act that may be so modified or excluded, such provision
of the Trust Indenture Act shall be deemed to apply to this Indenture as so
modified or excluded, as the case may be.

SECTION 108.  Effect of Headings and Table of Contents
              ----------------------------------------

          The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

SECTION 109.  Successors and Assigns
              ----------------------

     All covenants and agreements in this Indenture by the Company shall bind
its successors and assigns, whether so expressed or not.

SECTION 110.  Separability Clause
              -------------------

          In case any provision in this Indenture or in the Securities shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 111.  Benefits of Indenture
              ---------------------

     Nothing in this Indenture or in the Securities, express or implied, shall
give to any Person, other than the parties hereto and their successors hereunder
and the Holders, any benefit or any legal or equitable right, remedy or claim
under this Indenture.

SECTION 112.  Governing Law
              -------------

          This Indenture and the Securities shall be governed by and construed
in accordance with the laws of the State of New York.

SECTION 113.  Legal Holidays
              --------------

          In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the
Securities) payment of interest, if any, or principal (and premium, if any) need
not be made at such Place of Payment on such date, but may be made on the next
succeeding Business Day at such Place of Payment with the same force and effect
as if made on the Interest Payment Date or Redemption Date, or at the Stated
Maturity, and no interest shall accrue for the period from and after such
Interest Payment Date, Redemption Date or Stated Maturity, as the case may be.


                                  ARTICLE TWO

                                 SECURITY FORMS

SECTION 201.  Forms Generally

          The Securities of each series shall be in substantially the form set
forth in this Article, or in such other form as shall be established by or
pursuant to a Board Resolution or in one or more indentures supplemental hereto,
in each case with such appropriate insertions, omissions, substitutions and
other variations as are required or permitted by this Indenture, a Board
Resolution or one or more indentures supplemental hereto, and may have such
letters, numbers or other marks of identification and such legends or
endorsements placed thereon as may be required to comply with the rules of any
securities exchange or as may, consistently herewith, be determined by the
Director or Directors executing such Securities, as evidenced by the Director's
or Directors' execution of the Securities.  If the form of Securities of any
series is established by action taken pursuant to a Board Resolution, a copy of
an appropriate record of such action shall be certified by an authorized
Director or officer of the Company and delivered 

                                       13

SECTION 202.  Form of Face of Security
              ------------------------

          [If the Security is to be a Global Security, insert - This Security is
a Global Security within the meaning of the Indenture hereinafter referred to
and is [held by] [registered in the name] of a Book-Entry Depositary or a
nominee of a Book-Entry Depositary.  This Security is exchangeable for
Securities [held by] [registered in the name of] a person other than the Book-
Entry Depositary or its nominee only in the limited circumstances described in
the Indenture, and no transfer of this Security (other than a transfer of this
Security as a whole by the Book-Entry Depositary to a nominee of the Book-Entry
Depositary or by a nominee of the Book-Entry Depositary to the Book-Entry
Depositary or another nominee of the Book-Entry Depositary) may be [made]
[registered] except in limited circumstances.

          Unless this Global Security is presented by an authorized
representative of the Book-Entry Depositary to the issuer or its agent for
[registration of transfer], exchange or payment, and any definitive Security is
issued in the name or names as directed in writing by the Book-Entry Depositary,
ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY
PERSON IS WRONGFUL in as much as the [bearer] [registered owner] hereof, the
Book-Entry Depositary, has an interest herein.]

No. ___________________                                          $_____________

          SOUTHERN INVESTMENTS UK plc, a company duly organized and existing
under the laws of England and Wales (herein called the "Company", which term

commencing _____________________, at the rate per annum provided in the title
hereof, until the principal hereof is paid or made available for payment. The
interest so payable, and punctually paid or duly provided for, on any Interest
Payment Date will, as provided in such Indenture, be paid to [the bearer on such
Interest Payment Date,] [the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on the Regular
Record Date for such interest, which shall be the __________________ or
__________________ (whether or not a Business Day), as the case may be,
immediately preceding such Interest Payment Date.]  Any such interest not so
punctually paid or duly provided for will forthwith cease to be payable to [the
bearer on such Interest Payment Date] [the Person in whose name this Security
(or one or

registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to Holders of Securities of this series not less than 10 days prior to
such Special Record Date], or be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the
Securities of this series may be listed, and upon such notice as may be required
by such exchange, all as more fully provided in said Indenture.

[If the Security is not to bear interest prior to Maturity, insert -- The
principal of this Security shall not bear interest except in the case of a
default in payment of principal upon acceleration, upon redemption or at Stated
Maturity and in such case the overdue principal of this Security shall bear
interest at the rate of [yield to maturity] % per annum (to the extent that the
payment of such interest shall be legally enforceable), which shall accrue from
the date of such default in payment to the date payment of such principal has
been made or duly provided for.  Interest on any overdue principal shall be
payable on demand.  Any such interest on any overdue principal that is not so
paid on demand shall bear interest at the rate of [yield to maturity]% per annum
(to the extent that the payment of such interest shall be legally enforceable),
which shall accrue from the date of such demand for payment to the date payment
of such interest has been made or duly provided for, and such interest shall
also be payable on demand.]

any, on this Security will be made at the office or agency of the Company

     such Holder (or any predecessor Holder) was one of such owners requesting
     that definitive Registered Securities be so issued.

beneficial owner of the Security (or any interest therein) been the Holder of
the Security, he would not have been entitled to payment of Additional Amounts
by reason of any one or more of clauses (a) through (e) above.  If the Company
shall determine that Additional Amounts will not be payable because of the
immediately preceding sentence, the Company will inform such Holder promptly
after making such determination setting forth the reason(s) therefor.

          "Comparable Treasury Issue" means the United States Treasury security

maturity to the remaining term of the Securities of this series.

          "Comparable Treasury Price" means, with respect to any redemption
date, (i) the average of the bid and asked prices for the Comparable Treasury

          Notice of redemption shall be given as provided for in the Indenture
not less than 15 days nor more than 30 days prior to the date fixed for
redemption.

          If fewer than all the Securities of this series are to be redeemed,
selection of Securities of this series for redemption will be made by the
Trustee in any manner the Trustee deems fair and appropriate and that complies
with applicable legal and securities exchange requirements.

          Unless the Company defaults in payment of the redemption price, from
and after the redemption date, the Securities of this series or portions thereof
called for redemption will cease to bear interest, and the Holders thereof will
have no right in respect to such Securities of this series except the right to
receive the redemption price thereof.]

indebtedness of this security and (b) certain restrictive covenants upon
compliance by the Company with certain conditions set forth therein.

          If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture.  At any time after such declaration of acceleration with respect to
Securities of this series has been made, but before a judgment or decree for
payment of money has been obtained by the Trustee as provided in the Indenture,
if all Events of Default with respect to Securities of this series have been
cured or waived (other than the non-payment of principal of the Securities of
this series which has become due solely by reason of such declaration of
acceleration) then such declaration of acceleration and its consequences shall
be automatically annulled and rescinded.

          [If the Security is an Original Issue Discount Security, insert -- If
an Event of Default with respect to Securities of this series shall occur and be
continuing, an amount of principal of the Securities of this series (the
"Acceleration Amount") may be declared due and payable in the manner and with
the effect provided in the Indenture.  In case of a declaration of acceleration
on or before ________________ in any year, the Acceleration Amount per
____________ principal amount at Stated Maturity of the Securities shall be
equal to the amount set forth in respect of such date below:

              ---------------------                     ------------------
 
 
 
 

and in case of a declaration of acceleration on any other date, the Acceleration
Amount shall be equal to the Acceleration Amount as of the immediately preceding
date set forth in the table above, plus accrued original issue discount
(computed in accordance with the method used for calculating the amount of
original issue discount that accrues for Federal income tax purposes) from such
next preceding date to the date of declaration at the yield to maturity.  For
the purpose of this computation the yield to maturity is ____%.  Upon payment
(i) of the Acceleration Amount so declared due and payable and (ii) of interest

result of either (x) any change in, or amendment to, the laws or regulations of
the United Kingdom or any political subdivision or any authority or agency
thereof or therein having power to tax or levy duties, or any change in the
application or interpretation of such laws or regulations, which change or
amendment becomes effective on or after the [date of the underwriting agreement
with respect to the Securities of this series,] or (y) the issuance of
definitive Registered Securities pursuant to any of clauses (a), (b) or (d) of
the third following paragraph and (b) such obligation cannot be avoided by the
Company taking reasonable measures available to it, subject, as provided in the
Indenture, to the delivery by the Company of an Officers' Certificate stating
that the obligation referred to in (a) above cannot be avoided by the Company
taking reasonable measures available to it.

this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the registration
of transfer hereof or in exchange herefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Security.

satisfactory to the Company and the Security Registrar duly executed by, the
Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Securities of this series and of like tenor, of authorized
denominations and for the same aggregate principal amount, will be issued to the
designated transferee or transferees.]

the Indenture, the predecessor will be released from those obligations.

the Securities of this series or the Indenture or for any claim based on, in
respect of or by reason of, such obligations or their creation.  Each Holder of
the Securities of this series by accepting a Security of this series waives and
releases all such liability.  The waiver and release are part of the
consideration for the issuance of the Securities of this series.

          This Security shall not be valid until the Trustee or authenticating

     series pursuant to Sections 305, 306, 307 or 906, and except for any

     authenticated and delivered hereunder);

          (3)  the Person to whom any interest on a Security of the series shall
     be payable, if other than the bearer (in the case of a Global Bearer
     Security) or the Person in whose name the Security (or one or more
     Predecessor Securities) is registered at the close of business on the
     Regular Record Date for such interest (in the case of a Registered
     Security);

          (4)  the date or dates on which the principal of the Securities of the

     provisions or at the

<PAGE>
 
     option of a Holder thereof, and the period or periods within which, the
     price or prices at which and the terms and conditions upon which Securities
     of the series shall be redeemed, repaid or purchased, in whole or in part,
     pursuant to such obligation;

     America as at the time of payment is legal tender for payment of public or

     premium, if any) and interest, if any, on the Securities of the series
     shall be payable;

          (12) if the principal of (and premium, if any) or interest, if any, on

     the Securities are stated to be payable, the period or periods within
     which, and the terms and conditions upon which, such election may be made;

          (13) if the amount of payments of principal of (and premium, if any)
     or interest, if any, on the Securities of the series may be determined with

     for Securities of such series of like tenor and of authorized form and
     denomination and the circumstances under which any such changes may occur,
     if other than in the manner provided in Section 306 and (ii) the Book-Entry
     Depositary for such Global Security or Securities;

          (16) if the Company ever wishes to issue definitive Bearer Securities
     then all provisions relating to or governing such Bearer Securities will be
     set forth in an indenture supplemental hereto; and

          (17) any other terms of the series (which terms shall not be
     inconsistent with the provisions of this Indenture).

          All Securities of any one series shall be substantially identical
except as to denomination and except as may otherwise be provided in or pursuant
to the Board Resolution referred to above and set forth in the Officers'
Certificate referred to above or in any indenture supplemental hereto referred
to above.

          If any of the terms of the Securities of a series, including the form
of Security of such series, are established by action taken pursuant to a Board
Resolution, a copy of an 

                                       25
<PAGE>
 
appropriate record of such action shall be certified by the Secretary or an
Assistant Secretary or other authorized officer or Director of the Company, and
delivered to the Trustee at or prior to the delivery of the Company Order
contemplated by Section 303 for the authentication and delivery of such series
of Securities.

SECTION 302.   Denominations
               -------------

          The Securities of each series shall be issuable in bearer form or in
registered form without coupons, except as otherwise expressly provided in a
supplemental indenture hereto, in such denominations as shall be specified as
contemplated by Section 301. In the absence of any such provisions with respect
to the Securities of any series, the Securities of such series shall be issuable
in denominations of $1,000 and any integral multiple thereof.

SECTION 303.   Execution, Authentication, Delivery and Dating
               ----------------------------------------------

          The Securities shall be executed on behalf of the Company by any
Director, the Secretary or any other officer of the Company so authorized and
need not be attested.  Definitive Registered Securities of any series may have
the Company's seal reproduced thereon which need not be attested.  The
Securities of any series shall be executed by such additional Director or
officer, if any, as shall be specified pursuant to Section 301.  The signature
of any of these officers on the Securities may be manual or facsimile.

          Securities bearing the manual or facsimile signature of any individual
who was at any time the proper Director or officer of the Company shall bind the
Company, notwithstanding that such individual has ceased to hold such office
prior to the authentication and delivery of such Securities or did not hold such
office at the date of authentication of such Securities.

          At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities.  If the
form or terms of the Securities of the series have been established in or
pursuant to one or more Board Resolutions as permitted by Sections 201 and 301,
in authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to Section 601) shall be fully protected in
relying upon, an Opinion of Counsel stating,

          (a)  if the form of such Securities has been established by or
     pursuant to Board Resolution as permitted by Section 201, that such form
     has been established in conformity with the provisions of this Indenture;

          (b)  if the terms of such Securities have been established by or
     pursuant to Board Resolution as permitted by Section 301, that such terms
     have been established in conformity with the provisions of this Indenture;
     and

          (c)  that such Securities, when authenticated and delivered by the
     Trustee and issued by the Company in the manner and subject to any
     conditions specified in such opinion of Counsel, will constitute valid and
     legally binding obligations of the Company, enforceable in accordance with
     their terms, subject to bankruptcy, 

                                       26
<PAGE>
 
     insolvency, reorganization and other laws of general applicability relating
     to or affecting the enforcement of creditors' rights and to general
     principles of equity.

          Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the time
of authentication of each Security of such series if such documents are
delivered at or prior to the time of authentication upon original issuance of
the first Security of such series to be issued.

          Each Security shall be dated the date of its authentication.

          No Security shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee or an Authenticating Agent by manual signature, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered hereunder
and is entitled to the benefits of this Indenture.  Notwithstanding the
foregoing, if any Security shall have been authenticated and delivered hereunder
but never issued and sold by the Company, and the Company shall deliver such
Security to the Trustee for cancellation as provided in Section 310 together
with a written statement (which need not be accompanied by an Opinion of
Counsel) stating that such Security has never been issued and sold by the
Company, for all purposes of this Indenture such Security shall be deemed never
to have been authenticated and delivered hereunder and shall never be entitled
to the benefits of this Indenture.

SECTION 304.   Transfer Agent and Paying Agent
               -------------------------------

          For so long as the Securities are listed on the Luxembourg Stock
Exchange and such stock exchange shall so require, the Company shall maintain a
Paying Agent and Transfer Agent in Luxembourg.

          The Company shall enter into an appropriate agency agreement with any
Registrar, Transfer Agent or Paying Agent not a party to this Indenture, which
shall implement the provisions of this Indenture that relate to such Person.
The Company shall notify the Trustee of the name and address of any such Person.
If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall
act as such and shall be entitled to appropriate compensation therefor pursuant
to Section 607.  The Company initially appoints the Trustee as Registrar,
Transfer Agent and Principal Paying Agent in The City of New York and Bankers
Trust Luxembourg S.A. as Paying Agent and Transfer Agent in Luxembourg in
connection with the Securities.

SECTION 305.   Temporary Securities
               --------------------

          Pending the preparation of a permanent Global Security or definitive
Securities of any series, the Company may execute, and upon Company Order the
Trustee or the Authenticating Agent shall authenticate and deliver, temporary
Securities which are printed, lithographed, typewritten, mimeographed or
otherwise produced, in any authorized denomination, substantially of the tenor
of the definitive Securities in lieu of which they are issued, in registered
form or, if authorized, in bearer form, and with such appropriate 

                                       27
<PAGE>
 
insertions, omissions, substitutions and other variations as the [officer or
officers] executing such Securities may determine, as evidenced by their
execution of such Securities.

          If temporary Securities of any series are issued, the Company will
cause definitive Securities of that series to be prepared without unreasonable
delay.  After the preparation of definitive Securities of such series, the
temporary Securities of such series shall be exchangeable for definitive
Securities of such series upon surrender of the temporary securities of such
series at the office or agency of the Company in a Place of Payment for that
series, without charge to the Holder except as provided in Section 306 in
connection with a transfer and except that a Person receiving Definitive Bearer
Securities shall bear the cost of insurance, postage, transportation and the
like.  Upon surrender for cancellation of any one or more temporary Securities
of any series the Company shall execute and the Trustee or the Authenticating
Agent shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of the same series and of like tenor of
authorized denominations.

          Upon any exchange of a portion of a temporary Global Security for a
definitive Global Security for the individual Securities represented thereby
pursuant to this Section 305 or Section 306, the temporary Global Security shall
be endorsed by the Trustee to reflect the reduction of the principal amount of
such temporary Global Security, and such principal amount shall be reduced for
all purposes by the amount so exchanged and endorsed.

SECTION 306.   Registration, Registration of Transfer and Exchange
               ---------------------------------------------------

          The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the register maintained in such office and in any other
office or agency of the Company in a Place of Payment being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Registered Securities and of transfers of Registered Securities.
The Trustee is hereby appointed "Security Registrar" for the purpose of
registering Registered Securities and transfers of Registered Securities as
herein provided.  The Company may have one or more coregistrars and the term
"Security Registrar" includes any coregistrar.

          Upon surrender for registration of transfer of any Registered Security
of any series at the office or agency in a Place of Payment for that series, the
Company shall execute, and the Trustee or the Authenticating Agent shall
authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Registered Securities of the same series, of any
authorized denominations and of a like aggregate principal amount and tenor.

          At the option of the Holder, any Registered Security or Registered
Securities of any series, other than a Global Security, may be exchanged for
other Registered Securities of the same series, of any authorized denominations
and of a like aggregate principal amount and tenor, upon surrender of the
Registered Securities to be exchanged at such office or agency.  Whenever any
Securities are so surrendered for exchange, the Company shall execute, and upon
receipt of a Company Order the Trustee or the Authenticating Agent shall
authenticate and deliver, the Registered Securities which the Holder making the
exchange is entitled to receive.  Bearer Securities may not be delivered by the
Trustee, the Authenticating Agent or the Security Registrar in exchange for
Registered Securities.

                                       28
<PAGE>
 
          All Securities issued upon any registration of transfer or exchange of
Registered Securities shall be the valid obligations of the Company, evidencing
the same debt, and entitled to the same benefits under this Indenture, as the
Registered Securities surrendered upon such registration of transfer or
exchange.

          Every Registered Security presented or surrendered for registration of
transfer or for exchange shall (if so required by the Company or the Trustee) be
duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.

          Upon the exchange in whole of a Global Security for the definitive
Securities represented thereby, such Global Security shall be canceled by the
Trustee or delivered to the Trustee for cancellation.  Registered Securities
issued in exchange for a Global Security or any portion thereof pursuant to this
Section shall be registered in such names and in such authorized denominations
as the Book-Entry Depositary for such Global Security shall instruct in writing
the Trustee and the Security Registrar.  The Trustee or the Security Registrar
shall deliver such Registered Securities to the Persons in whose names such
Registered Securities are so registered.

          Interests in a Permanent Global Security may be exchanged for
definitive Registered Securities of the same series only under the circumstances
provided in this Indenture or in an indenture supplemental hereto pursuant to
which Securities of that series are issued or in the Securities of that Series.
In such event the Company will execute, and the Trustee or the Authenticating
Agent, upon receipt of a Company Order for the authentication and delivery of
definitive Registered Securities of such series will authenticate and deliver
such definitive Registered Securities.  Any such definitive Registered
Securities so issued shall be registered in the name of such Person or Persons
as the Book-Entry Depositary shall instruct the Trustee and the Security
Registrar in writing.  Upon the exchange in whole of a Permanent Global Security
for definitive Registered Securities in equal aggregate principal amount, such
Permanent Global Security shall be delivered to the Trustee for cancellation.
Interests in a Permanent Global Security may not be exchanged for definitive
Bearer Securities.  Notwithstanding the foregoing, interests in a Global
Security may not be exchanged for definitive Registered Securities during the
sixteen day period immediately prior to and including each Interest Payment
Date.

          No service charge shall be made to the Holder for any registration of
transfer or exchange of Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Sections 305, 906 or 1107 not involving any transfer.

          The Company shall not be required (i) to issue, register the transfer
of or exchange Securities of any series during a period beginning at the opening
of business 15 days before the day of the mailing of a notice of redemption
under Section 1103 and ending at the close of business on the day of such
mailing, (ii) to register the transfer of or exchange any Security so selected
for redemption in whole or in part, except the unredeemed portion of any
Security being redeemed in part or (iii) to exchange any Bearer Security so
selected for redemption except that such a Bearer Security may be exchanged for
a Registered Security of the series (but only if and under the circumstances for
which the Securities of such series are issuable as Registered Securities),
PROVIDED that such Registered Security shall be immediately 
- --------                                                                   

                                       29
<PAGE>
 
surrendered for redemption with written instructions for payment consistent with
the provisions of this Indenture.

          The provisions of this Section 306 are, with respect to any Global
Security, subject to Section 312 hereof.

SECTION 307.   Mutilated, Destroyed, Lost and Stolen Securities
               ------------------------------------------------

          If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

          If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
and (ii) such Security or indemnity as may be required by them to save each of
them and any agent of either of them harmless, then, in the absence of notice to
the Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and upon its written request the Trustee
shall authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

          In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

          Upon the issuance of any new Security under this Section 307, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

          Every new Security of any series issued pursuant to this Section 307
in lieu of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities of that series duly issued hereunder.

          The provisions of this Section 307 are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities.

SECTION 308.   Payment of Interest; Interest Rights Reserved
               ---------------------------------------------

          Interest on any Security which is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid (in the case of a
Bearer Security) to the bearer thereof and (in the case of a Registered
Security) to the Person in whose name that Registered Security (or one or more
Predecessor Securities) is registered at the close of business on the Regular
Record Date for such interest.

                                       30
<PAGE>
 
          Payment of interest, if any, in respect of any Registered Security
will be made by check mailed to the address of the Person entitled thereto as
such person's address appearing in the Security Register. Payment of interest,
if any, in respect of any Registered Security may also be made, in the case of a
Holder of at least U.S. $1,000,000 aggregate principal amount of Registered
Securities, and payment of interest, if any, in respect of a Permanent Global
Security shall be made, by wire transfer to a U.S. Dollar account maintained by
the Holder with a bank in the United States; provided that such Holder elects
payment by wire transfer by giving written notice to the Trustee or a Paying
Agent to such effect designating such account no later than 15 days immediately
preceding the relevant due date for payment (or such other date as the Trustee
may accept in its discretion).

          Any interest on any Security of any series which is payable but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall, in the case of Registered Securities,
forthwith cease to be payable to the Holder thereof on the relevant Regular
Record Date by virtue of having been such Holder, and such Defaulted Interest
may be paid by the Company, at its election in each case, as provided in Clause
(1) or (2) below:

          (1)  The Company may elect to make payment of any Defaulted Interest
     to the Persons in whose names the Registered Securities of such series (or
     their respective Predecessor Securities) are registered at the close of
     business on a Special Record Date for the payment of such Defaulted
     Interest, which shall be fixed in the following manner.  The Company shall
     notify the Trustee in writing of the amount of Defaulted Interest proposed
     to be paid on each Registered Security of such series and the date of the
     proposed payment, and at the same time the Company shall deposit with the
     Trustee an amount of money equal to the aggregate amount proposed to be
     paid in respect of such Defaulted Interest or shall make arrangements
     satisfactory to the Trustee for such deposit prior to the date of the
     proposed payment, such money when deposited to be held in trust for the
     benefit of the Persons entitled to such Defaulted Interest as in this
     clause provided.  Thereupon the Trustee shall fix a Special Record Date for
     the payment of such Defaulted Interest which shall be not more than 15 days
     and not less than 10 days prior to the date of the proposed payment and not
     less than 10 days after the receipt by the Trustee of the notice of the
     proposed payment.  Unless the Trustee is acting as the Security Registrar,
     promptly after such Special Record Date, the Company shall furnish the
     Trustee with a list, or shall make arrangements satisfactory to the Trustee
     with respect thereto, of the names and addresses of, and respective
     principal amounts of such Registered Securities held by, the Holders
     appearing on the Security Register at the close of business on such Special
     Record Date.  The Trustee shall promptly notify the Company of such Special
     Record Date and, in the name and at the expense of the Company, shall cause
     notice of the proposed payment of such Defaulted Interest and the Special
     Record Date therefor to be mailed, first-class postage prepaid, to each
     Holder of Securities of such series at his address as it appears in the
     Security Register, not less than 10 days prior to such Special Record Date.
     Notice of the proposed payment of such Defaulted Interest and the Special
     Record Date therefor having been so mailed, such Defaulted Interest shall
     be paid to the Persons in whose names the Securities of such series (or
     their respective Predecessor Securities) are registered at the close of
     business on such Special Record Date and shall no longer be payable
     pursuant to the following clause (2).

          (2)  The Company may make payment of any Defaulted Interest on the
     Registered Securities of any series or any Permanent Global Security in any
     other lawful manner not inconsistent with the requirements of any
     securities exchange on 

                                       31
<PAGE>
 
     which such Registered Securities may be listed, and upon such notice as may
     be required by such exchange.

     Defaulted Interest on Global Bearer Securities shall be payable to the
bearer thereof at the time of payment of such Defaulted Interest by the Company.

          Subject to the foregoing provisions of this Section 308, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security, shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

SECTION 309.   Persons Deemed Owners
               ---------------------

          Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Registered Security is registered as the
owner of such Registered Security for the purpose of receiving payment of
principal of (and premium, if any) and (subject to Section 308) interest, if
any, on such Registered Security and for all other purposes whatsoever, whether
or not such Registered Security be overdue, and neither the Company, the Trustee
nor any agent of the Company or the Trustee shall be affected by notice to the
contrary.  All such payments so made to any such person, or upon such person's
order, shall be valid, and, to the extent of the sums so paid, effectual to
satisfy and discharge the liability for monies payable upon any such Security.

          The Company, the Trustee and any agent of the Company or the Trustee
may treat the Book-Entry Depositary for a Global Bearer Security as the absolute
owner of such Bearer Security for the purpose of receiving payment thereof or on
account thereof and for all other purposes whatsoever, whether or not such
Global Bearer Security or coupon be overdue, and neither the Company or the
Trustee nor any agent of the Company or the Trustee shall be affected by notice
to the contrary.

          No holder of any beneficial interest in any Global Security held on
its behalf by a Book-Entry Depositary shall have any rights under this Indenture
with respect to such Global Security, and such Book-Entry Depositary may be
treated by the Company, the Trustee, and any agent of the Company or the Trustee
as the owner of such Global Security for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall impair, as between a Book-
Entry Depositary and such holders of beneficial interests, the operation of
customary practices governing the exercise of the rights of the Book-Entry
Depositary as holder of any Security.

SECTION 310.   Cancellation
               ------------

          All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly canceled by it.  The Company may at any time deliver to
the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Company may have acquired in any manner
whatsoever, and all Securities so delivered shall be promptly canceled by the
Trustee.  No Securities shall be authenticated in lieu of or in exchange for any
Securities canceled as 

                                       32
<PAGE>
 
provided in this Section 310, except as expressly permitted by this Indenture.
All canceled Securities held by the Trustee shall be disposed of as directed by
a Company Order.

SECTION 311.   Computation of Interest
               -----------------------

          Except as otherwise specified as contemplated by Section 301 for
Securities of any series, interest, if any, on the Securities of each series
shall be computed on the basis of a 360-day year of twelve 30-day months.

SECTION 312.   Global Securities
               -----------------

          If the Company shall establish pursuant to Section 301 that the
Securities of a particular series are to be issued in the form of a Global
Security, then the Company shall execute and the Trustee shall, in accordance
with Section 303, authenticate and deliver, a Global Security or Securities
which (i) shall represent, and shall be denominated in an aggregate amount equal
to the aggregate principal amount of, all of the Outstanding Securities of such
series, (ii) shall be in bearer form or, if in registered form, registered in
the name of the Book-Entry Depositary or its nominee, (iii) shall be delivered
by the Trustee to the Book-Entry Depositary or pursuant to the Book-Entry
Depositary's instruction and (iv) shall bear a legend substantially to the
following effect:

               "This Security is a Global Security within the meaning of the
     Indenture hereinafter referred to and if this Security is in bearer form,
     is held by a Book-Entry Depositary or, if this Security is in registered
     form, is registered in the name of a Book-Entry Depositary or a nominee of
     a Book-Entry Depositary.  This Security is exchangeable for Securities
     registered in the name of a person other than the Book-Entry Depositary or
     its nominee only in the limited circumstances described in the Indenture,
     and no transfer of this Security (other than a transfer of this Security as
     a whole by the Book-Entry Depositary to a nominee of the Book-Entry
     Depositary or by a nominee of the Book-Entry Depositary to the Book-Entry
     Depositary or another nominee of the Book-Entry Depositary) may be made or
     registered, as the case may be, except in limited circumstances.

               Unless this Global Security is presented by an authorized
     representative of the Book-Entry Depositary to the Company or its agent for
     registration of transfer, exchange or payment, and any definitive Security
     is issued in the name or names as directed in writing by the Book-Entry
     Depositary, ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE
     BY OR TO ANY PERSON IS WRONGFUL in as much as the bearer or, if in
     registered form, the registered owner hereof, the Book-Entry Depositary,
     has an interest herein."

          Notwithstanding the provisions of Section 306, the Global Security of
a series may be transferred, in whole but not in part and in the manner provided
in Section 306, only to another nominee of the Book-Entry Depositary for such
series, or to a successor Book-Entry Depositary for such series selected or
approved by the Company or to a nominee of such successor Book-Entry Depositary.

          The circumstances, if any, under which the Global Security of a series
may be exchanged for definitive Registered Securities of such series shall be as
specified in an indenture supplemental hereto pursuant to which the Securities
of such series are issued.  In such event the Company will execute, and, subject
to Section 306, the Trustee, upon receipt of 

                                       33
<PAGE>
 
an Officers' Certificate evidencing such determination by the Company, will
authenticate and deliver Securities of such series in definitive registered form
without coupons, in authorized denominations, and in an aggregate principal
amount equal to the principal amount of the Global Securities of such series in
exchange for such Global Securities. Upon the exchange of the Global Securities
for such Securities in definitive registered form without coupons, in authorized
denominations, the Global Securities shall be canceled by the Trustee.  Such
Securities in definitive registered form issued in exchange for the Global
Securities pursuant to this Section 312, shall be registered in such names and
in such authorized denominations as the Book-Entry Depositary, pursuant to the
instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee.  The Trustee shall deliver Securities to the Book-Entry
Depositary for delivery to the persons in whose names such Securities are so
registered.

          No Security that is not a Global Security may be payable to bearer
(except as otherwise provided in an indenture supplemental hereto pursuant to
Section 301(16).

SECTION 401.   Satisfaction and Discharge of Indenture
               ---------------------------------------

          This Indenture shall upon Company Request cease to be of further
effect (except as to any surviving rights of registration of transfer or
exchange of Securities herein expressly provided for and rights to receive
payments of any principal, premium or interest in respect thereof and any right
to receive any Additional Amount as provided in Section 1009), and the Trustee
shall execute proper instruments acknowledging satisfaction and discharge of
this Indenture, when

          (1)  either (A) all Securities theretofore authenticated and delivered
     (other than (i) Securities which have been destroyed, lost or stolen and
     which have been replaced or paid as provided in Section 307 and (ii)
     Securities for whose payment money has theretofore been deposited in trust
     with the trustee or any paying agent or segregated and held in trust by the
     Company and thereafter repaid to the Company or discharged from such trust,
     as provided in Section 1003) have been delivered to the Trustee for
     cancellation; or

          (B)  all such Securities not theretofore delivered to the Trustee for
     cancellation

               (i)    have become due and payable, or

               (ii)   will become due and payable at their Stated Maturity
          within one year, or

               (iii)  are to be called for redemption within one year under
          arrangements for the giving of notice of redemption by the Trustee in
          the name, and at the expense, of the Company, or

               (iv)   are deemed paid and discharged pursuant to Section 403, as
          applicable.

     and the Company, in the case of (i) or (ii) above, has deposited or caused
     to be deposited with the Trustee as trust funds in trust for the purpose an
     amount of (a) money in the currency or units of currency in which such
     Securities are payable, or (b) U.S. Government Obligations (denominated in
     the same currency or units of currency in which such Securities are
     payable) which through the payment of interest and principal in respect
     thereof in accordance with their terms will provide not later than one day
     before the Stated Maturity or Redemption Date, as the case may be, money in
     an amount, or (c) a combination of money or U.S. Government Obligations as
     provided in (d) above, in each case, sufficient to pay and discharge the
     entire indebtedness on such Securities not theretofore delivered to the
     Trustee for cancellation, for principal (and premium, if any) and interest,
     if any, to the date of such deposit (in the case of Securities which have
     become due and payable) or to the Stated Maturity or Redemption Date, as
     the case may be;

          (2)  the Company has paid or caused to be paid all other sums payable
     hereunder by the Company; and

          (3)  the Company has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel, each stating that all conditions precedent
     herein provided for relating to the satisfaction and discharge of this
     Indenture have been complied with.

          Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607, the obligations of
the Trustee to any Authenticating Agent under Section 614 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of clause (1) of
this Section 401 or if money or U.S. Government Obligations shall have been
deposited with or received by the Trustee pursuant to Section 403, the
obligations of the Trustee under Section 402 and the last paragraph of Section
1003 shall survive.

SECTION 402.   Application of Trust Money
               --------------------------

          (a)  Subject to the provisions of the last paragraph of Section 1003,
all money or U.S. Government Obligations deposited with the Trustee pursuant to
Sections 401 or 403 and all money received by the Trustee in respect of U.S.
Government Obligations deposited with the Trustee pursuant to Sections 401 or
403, shall be held in trust and applied by it, in accordance with the provisions
of the Securities and this Indenture, to the payment, to the persons entitled
thereto, of the principal of (and premium, if any) and interest, if any, on the
Securities for whose payment such money has been deposited with or received by
the Trustee or to make mandatory sinking fund payments or analogous payments as
provided by Sections 401 or 403.

          (b)  The Company shall pay and shall indemnify the Trustee against any
tax, fee or other charge imposed on or assessed against U.S. Government
Obligations deposited pursuant to Sections 401 or 403 or the interest and
principal received in respect of such obligations other than any payable by or
on behalf of Holders.

          (c)  The Trustee shall deliver or pay to the Company from time to time
upon Company Request any U.S. Government Obligations or money held by it as
provided in Sections 401 or 403 which, in the opinion of a nationally recognized
firm of independent certified public accountants expressed in a written
certification thereof delivered to the 

                                       35
<PAGE>
 
Trustee, are then in excess of the amount thereof which then would have been
required to be deposited for the purpose for which such U.S. Government
Obligations or money was deposited or received. This provision shall not
authorize the sale by the Trustee of any U.S. Government Obligations held under
this Indenture.

          (d)  Any monies paid by the Company to the Trustee or any Paying
Agent, or held by the Company in trust, for the payment of the principal of or
any interest or Additional Amounts on any Securities and remaining unclaimed at
the end of two years after such principal, interest or Additional Amounts become
due and payable will be repaid to the Company, or released from the trust, upon
its written request, and upon such repayment or release all liability of the
company, the Trustee and such Paying Agent with respect thereto will cease.

SECTION 403.   Satisfaction, Discharge and Defiance of Securities of any Series
               ----------------------------------------------------------------

          The Company, at its option, (a) will be discharged from any and all
obligations in respect of the Securities of a series  (except in each case for
the obligations to register the transfer or exchange of the Securities of that
series, replace stolen, lost or mutilated Securities of that series, maintain
paying agencies and hold moneys for payment in trust); or (b) omit to comply
with any term, provision or condition set forth in Sections 801, 1004 and 1005
with respect to the Securities of any series, provided that the following
conditions shall have been satisfied:

          (1)  The Company has deposited or caused to be irrevocably deposited
     (except as provided in Section [607], [402(c)] and the last paragraph of
     Section [1003]) with the Trustee (specifying that each deposit is pursuant
     to this Section 403) as trust funds in trust, specifically pledged as
     security for, and dedicated solely to, the benefit of the Holders of the
     Securities of such series, (i) money or (ii) U.S. Government Obligations
     which through the payment of interest and principal in respect thereof in
     accordance with their terms will provide money in an amount, or (iii) a
     combination thereof, in each case, sufficient to pay and discharge the
     principal and interest on the outstanding Securities of such series on the
     dates such payments are due in accordance with the terms of the Securities
     of such series, (or if the Company has designated a redemption date
     pursuant to the final sentence of this paragraph, to and including the
     redemption date so designated by the Company), and no Event of Default or
     event which with notice or lapse of time would become an Event of Default
     (including by reason of such deposit) with respect to the Securities of
     such series shall have occurred and be continuing on the date of such
     deposit.  To exercise any such option, the Company is required to deliver
     to the Trustee (x) an Opinion of Counsel to the effect that the Holders of
     the Securities of such series will not recognize income, gain or loss for
     federal income tax purposes as a result of such deposit, defeasance and
     discharge of certain obligations, which in the case of (a) must be based on
     a change in law or a ruling by the U.S. Internal Revenue Service and (y) an
     Officers' Certificate as to compliance with all conditions precedent
     provided for in the Indenture relating to the satisfaction and discharge of
     the Securities of such series.  If the Company shall wish to deposit or
     cause to be deposited money or U.S. Government Obligations to pay or
     discharge the principal of (and premium, if any) and interest, if any, on
     the outstanding Securities of such series to and including a Redemption
     Date on which all of the outstanding Securities of such series are to be
     redeemed, such Redemption Date shall be irrevocably designated by a Board
     Resolution delivered to the Trustee on or prior to the date of deposit of
     such money or U.S. Government Obligations, and such Board 

                                       36
<PAGE>
 
     Resolution shall be accompanied by an irrevocable Company Request that the
     Trustee give notice of such redemption in the name and at the expense of
     the Company not less than 15 nor more than 30 days prior to such Redemption
     Date in accordance with this Indenture.

SECTION  501.  Events of Default
               -----------------

          "Event of Default", wherever used herein with respect to Securities of
any series, means any one of the following events:

          (1)  default in the payment of any interest or any Additional Amounts
     upon any Security of that series when it becomes due and payable and
     continuance of such default for a period of 30 days; or

          (2)  default in the payment of the principal of (or premium, if any,
     on) any Security of that series at its Maturity; or

          (3)  default in the payment of any sinking fund installment, when and
     as due by the terms of a Security of that series and continuance of such
     default for a period of 15 days; or

          (4)  material default in the performance, or material breach, of any
     covenant or obligation of the Company in this Indenture (other than a
     covenant a default in whose performance or whose breach is elsewhere in
     this Section 501 specifically dealt with or which has expressly been
     included in this Indenture solely for the benefit of a series of Securities
     other than that series) and continuance of such material default or breach
     for a period of 60 days after there has been given, by registered or
     certified mail, to the Company by the Trustee or to the Company and the
     Trustee by the Holders of at least 25% in aggregate principal amount of the
     Outstanding Securities of that series a written notice specifying such
     default or breach and requiring it to be remedied and stating that such
     notice is a "Notice of Default" hereunder; or

          (5)  if this event shall be made to constitute an Event of Default
     with respect to the Securities of a particular series, a default in the
     payment of the principal of any bond, debenture, note or other evidence of
     indebtedness, in each case for money borrowed by the Company or any
     Significant Subsidiary, or in the payment of principal under any mortgage,
     indenture (including this Indenture) or instrument under which there may be
     issued or by which there may be secured or evidenced any indebtedness for
     money borrowed by the Company or any Significant Subsidiary, which default
     for payment of principal is in an aggregate principal amount exceeding
     $50,000,000 (or its equivalent in any other currency or currencies) when
     such indebtedness becomes due and payable (whether at maturity, upon
     redemption or acceleration or otherwise), if such default shall continue
     unremedied or unwaived for more than 30 Business Days and the time for
     payment of such amount has not been expressly extended; provided, however,
                                                             ----------------- 
     that, subject to the provisions of Sections 601 and 602, the Trustee shall
     not be deemed to have knowledge of such default unless either (A) a
     Responsible Officer of 

                                       37
<PAGE>
 
     the Trustee shall have actual knowledge of such default or (B) the Trustee
     shall have received written notice thereof from the Company, from any
     Holder, from the holder of any such indebtedness or from the trustee under
     any such mortgage, indenture or other instrument; and provided, further,
                                                           --------  -------
     that if such default under such indenture or instrument shall be remedied
     or cured by the Company or such Significant Subsidiary or waived by the
     holders of such indebtedness, then the Event of Default hereunder by reason
     thereof shall be deemed likewise to have been remedied, cured or waived
     without further action upon the part of the Trustee or any of the Holders;
     or

          (6)  The failure of the Company or a Significant Subsidiary generally
     to pay its debts as they become due, or the admission in writing of its
     inability to pay its debts generally, or the making of a general assignment
     for the benefit of its creditors, or the institution of any proceeding by
     or against the Company or a Significant Subsidiary (other than any such
     proceeding brought against the Company or a Significant Subsidiary that is
     dismissed within 180 days from the commencement thereof) seeking to
     adjudicate it  bankrupt or insolvent, or seeking liquidation (other than a
     solvent liquidation), winding up, reorganization, arrangement, adjustment,
     protection, relief or composition of it or its debts under any law relating
     to bankruptcy, insolvency, reorganization, moratorium or relief of debtors,
     or seeking the entry of an order for relief or appointment of an
     administrator, receiver, trustee, intervenor or other similar official for
     it or for any substantial part of its property, or the taking of any action
     by the Company or a Significant Subsidiary to authorize any of the actions
     set forth in this subparagraph (6); or

          (7)  Any other Event of Default provided in the supplemental indenture
     or provided in or pursuant to the Board Resolution under which such series
     of Securities is issued or in the form of Security for such series.

SECTION 502.   Acceleration of Maturity; Rescission and Annulment
               --------------------------------------------------

          If an Event of Default with respect to Securities of any series at the
time Outstanding occurs and is continuing, then in every such case the Trustee
or the Holders of not less than 25% in aggregate principal amount of the
Outstanding Securities of that series may declare the principal amount (or, if
any of the Securities of that series are Original Issue Discount Securities,
such portion of the principal amount of such Securities as may be specified in
the terms thereof) of all of the Securities of that series to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders), and upon any such declaration such principal amount (or specified
amount) shall become immediately due and payable.

          At any time after such declaration of acceleration with respect to
Securities of any series has been made, but before a judgment or decree for
payment of money has been obtained by the Trustee as hereinafter in this Article
provided, if all Events of Default with respect to Securities of that series
have been cured or waived (other than the non-payment of principal of the
Securities which has become due solely by reason of such declaration of
acceleration) then such declaration of acceleration and its consequences shall
be automatically annulled and rescinded.

          No such rescission shall affect any subsequent default or impair any
right consequent thereon.

                                       38
<PAGE>
 
          For all purposes under this Indenture, if a portion of the principal
of any Original Issue Discount Securities shall have been accelerated and
declared due and payable pursuant to the provisions hereof, then, from and after
such declaration, unless such declaration has been rescinded and annulled, the
principal amount of such Original Issue Discount Securities shall be deemed, for
all purposes hereunder, to be such portion of the principal thereof as shall be
due and payable as a result of such acceleration, and payment of such portion of
the principal thereof as shall be due and payable as a result of such
acceleration, together with interest, if any, thereon and all other amounts
owing thereunder, shall constitute payment in full of such Original Issue
Discount Securities.

SECTION 503.   Collection of Indebtedness and Suits for Enforcement by Trustee
               ---------------------------------------------------------------

          The Company covenants that if

          (1)  default is made in the payment of any interest on any Security of
     a series when such interest becomes due and payable and such default
     continues for a period of 30 days, or

          (2)  default is made in the payment of the principal of (or premium,
     if any, on) any Security of a series at the Stated Maturity thereof,

the Company will, upon written demand of the Trustee, pay to it, for the benefit
of the Holders of such Securities of such series, the whole amount then due and
payable on such Securities of such series for principal (and premium, if any)
and interest, if any, and, to the extent that payment of such interest shall be
legally enforceable, interest on any overdue principal (and premium, if any) and
any overdue interest, at the rate or rates prescribed therefor in such
Securities of such series, and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel.

          If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon such Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon such Securities, wherever
situated.

          If any Event of Default with respect to Securities of any series
occurs and is continuing, the Trustee may in its discretion proceed to protect
and enforce its rights and the rights of the Holders of Securities of such
series by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights.

SECTION 504.   Trustee May File Proofs of Claim
               --------------------------------

          In case of the pendency of any receivership, insolvency, liquidation
(other than a solvent liquidation), bankruptcy, reorganization, arrangement,
adjustment, composition or other judicial proceeding relative to the Company or
any other obligor upon the Securities or the property of the Company or of such
other obligor or their creditors, the Trustee (irrespective of whether the
principal of the Securities shall then be due and payable as therein expressed
or by declaration or otherwise and irrespective of whether the Trustee shall
have 

                                       39
<PAGE>
 
made any demand on the Company for the payment of overdue principal or interest)
shall be entitled and empowered, by intervention in such proceeding or
otherwise,

          (i)    to file and prove a claim for the whole amount of principal
     (and premium, if any) and interest owing and unpaid in respect of the
     Securities and to file such other papers or documents as may be necessary
     or advisable in order to have the claims of the Trustee (including any
     claim for the reasonable compensation, expenses, disbursements and advances
     of the Trustee, its agents and counsel) and of the Holders allowed in such
     judicial proceeding, and

          (ii)   to collect and receive any moneys or other property payable or
     deliverable on any such claims and to distribute the same;

any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this

          If the Trustee or any Holder has instituted any proceeding to enforce

discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder, and
thereafter all rights and remedies of the Company, the Trustee and the Holders
shall continue as though no such proceeding had been instituted.

SECTION 510.   Rights and Remedies Cumulative
               ------------------------------

          Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities in the last paragraph

Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

Securities of any series shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred on the Trustee, with respect to the
Securities of such series, provided that

          (1)  such direction shall not be in conflict with any rule of law or
     with this Indenture,

          (2)  the Trustee may take any other action deemed proper by the
     Trustee which is not inconsistent with such direction, and

          (3)  the Trustee shall not determine that the action so directed would
     be prejudicial to Holders not taking part in such action.

SECTION 513.   Waiver of Past Defaults
               -----------------------

     interest, if any, on any Security of such series, or

          (2)  in respect of a covenant or provision hereof which under Article
     Nine cannot be modified or amended without the consent of the Holder of
     each Outstanding Security of such series affected.

          Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

SECTION 514.   Undertaking for Costs.
               --------------------- 

          All parties to this Indenture agree, and each Holder of any Security
by his acceptance thereof shall be deemed to have agreed, that any court may in
its discretion require, in any suit for the enforcement of any right or remedy
under this Indenture, or in any suit against the Trustee for any action taken or
omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant in such suit,
but the provisions of this Section 514 shall not apply to any suit instituted by
the Trustee, to any suit instituted by any Holder, or group of Holders, holding
in the aggregate more than 10% in principal amount of the outstanding Securities
of any series, or to any suit instituted by any Holder for the enforcement of
the payment of the principal of or interest, if any, on any Security on or after
the Stated Maturity or Maturities expressed in such Security.

     examine the same to determine whether or not they conform to the
     requirements of this Indenture.

          (b)  In case a default has occurred and is continuing, the Trustee
     shall exercise such of the rights and powers vested in it by this

     a prudent man would exercise or use under the circumstances in the conduct
     of his own affairs.

          (c)  No provision of this Indenture shall be construed to relieve the
     Trustee from liability for its own negligent action, its own negligent
     failure to act, or its own willful misconduct, except that

               (1)  the Trustee shall not be liable for any error of judgment
     made in good faith by a Responsible Officer, unless the Trustee was
     negligent in ascertaining the pertinent facts; and

     spend or risk its own funds or otherwise incur any financial liability in

     of its rights or powers, if repayment of such funds or adequate indemnity
     against such risk or liability satisfactory to the Trustee has not been
     assured to it.

               (3)  the Trustee shall not be liable with respect to any action
     taken or omitted to be taken by it in good faith in accordance with the
     direction of the Holders of not less than a majority in principal amount of
     the outstanding Securities of any series, determined as provided in Section
     512, relating to the time, method and place of conducting any proceeding
     for any remedy available to the Trustee, or exercising any trust or power
     conferred upon the Trustee, under this Indenture with respect to the
     Securities of such series; and

          (d)  Whether or not therein expressly so provided, every provision of
     this Indenture relating to the conduct or affecting the liability of or
     affording protection to the Trustee shall be subject to the provisions of

of such series; and provided, further, that in the case of any default of the

          (2)  the Trustee shall cease to be eligible under Section 609 and

Trustee with respect to all Securities, or (ii) subject to Section 514, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.

          (e)  If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Securities of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Securities of that or those series (it being understood that any such
successor Trustee may be appointed with respect to the Securities of one or more
or all of such series and that at any time there shall be only one Trustee with
respect to the Securities of any particular series) and shall comply with the
applicable requirements of Section 611.  If no successor Trustee with respect to
the Securities of any series shall have been so appointed by the Company and
accepted appointment in the manner required by Section 611, any Holder who has

may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series.

removal of the Trustee with respect to the Securities of any series and each

SECTION 611.   Acceptance of Appointment by Successor
               --------------------------------------

          (a)  In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on the request
of the Company or the successor Trustee, such retiring Trustee shall, upon
payment of its charges, 

                                       48
<PAGE>
 
execute and deliver an instrument transferring to such successor Trustee all the
rights, powers and trusts of the retiring Trustee and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder.

          (b)  In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co trustees of the
same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee; and upon the execution and delivery of such supplemental
indenture the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates; but on request of the company or any successor trustee, such
retiring Trustee shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder with
respect to the Securities of that or those series to which the appointment of
such successor Trustee relates.

          (c)  Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in paragraph (a) or (b) of this Section 611, as the case may be.

          (d)  No successor Trustee shall accept its appointment unless at the
time of such acceptance such successor Trustee shall be qualified and eligible
under this Article.

SECTION 612.   Merger, Conversion, Consolidation or Succession to Business
               -----------------------------------------------------------

          Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
                                                                 --------     
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto.  In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so 

                                       49
<PAGE>
 
authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities.

SECTION 613.   Preferential Collecting of Claims Against Company
               -------------------------------------------------

          (a)  Subject to Subsection (b) of this Section 613, if the Trustee
shall be or shall become a creditor, directly or indirectly, secured or
unsecured, of the Company within three months prior to a default, as defined in
Subsection (c) of this Section 613, or subsequent to such a default, then,
unless and until such default shall be cured, the Trustee shall set apart and
hold in a special account for the benefit of the Trustee individually, the
Holders of the Securities and the holders of other indenture securities, as
defined in Subsection (c) of this Section 613:

          (1)  an amount equal to any and all reductions in the amount due and
     owing upon any claim as such creditor in respect of principal or interest
     effected after the beginning of such three months' period and valid as
     against the Company and its other creditors, except any such reduction
     resulting from the receipt or disposition of any property described in
     paragraph (2) of this Subsection, or from the exercise of any right of set-
     off which the Trustee could have exercised if a petition in bankruptcy had
     been applied by or against the Company upon the date of such default; and

          (2)  all property received by the Trustee in respect of any claims as
     such creditor, either as security therefor, or in satisfaction or
     composition thereof, or otherwise, after the beginning of such three
     months' period, or an amount equal to the proceeds of any such property, if
     disposed of, subject, however, to the rights, if any, of the Company and
                  -------  -------                                           
     its other creditors in such property or such proceeds.

          Nothing herein contained, however, shall affect the right of the
     Trustee:

          (A)  to retain for its own account (i) payments made on account of any
     such claim by any Person (other than the Company) who is liable thereon,
     and (ii) the proceeds of the bona fide sale of any such claim by the
     Trustee to a third Person, and (iii) distributions made in cash, securities
     or other property in respect of claims filed against the Company in
     bankruptcy or receivership or in proceedings for reorganization pursuant to
     the Federal Bankruptcy Act or applicable State law;

          (B)  to realize, for its own account, upon any property held by it as
     security for any such claim, if such property was so held prior to the
     beginning of such three months' period;

          (C)  to realize, for its own account, but only to extent of the claim
     hereinafter mentioned, upon any property held by it as security for any
     such claim, if such claim was created after the beginning of such three
     months' period and such property was received as security therefor
     simultaneously with the creation thereof, and if the Trustee shall sustain
     the burden of proving that at the time such property was so received the
     Trustee had no reasonable cause to believe that a default, as defined in
     Subsection (c) of this Section 613, would occur within three months; or

          (D)  to receive payment on any claim referred to in paragraph (B) or
     (C) , against the release of any property held as security for such claim
     as provided in 

                                       50
<PAGE>
 
     paragraph (B) or (C) , as the case may be, to the extent of the fair value
     of such property.

          For the purposes of paragraphs (B), (C) and (D), property substituted
after the beginning of such three months' period for property held as security
at the time of such substitution shall, to the extent of the fair value of the
property released, have the same status as the property released, and, to the
extent that any claim referred to in any of such paragraphs is created in
renewal of or in substitution for or for the purpose of repaying or refunding
any pre-existing claim of the Trustee as such creditor, such claim shall have
the same status as such pre-existing claim.

          If the Trustee shall be required to account for the funds and property
held in such special account, the proceeds thereof shall be apportioned among
the Trustee, the Holders and the holders of other indenture securities in such
manner that the Trustee, the Holders and the holders of other indenture
securities realize, as a result of payments from such special account and
payments of dividends on claims filed against the Company in bankruptcy or
receivership or in proceedings for reorganization pursuant to the Federal
Bankruptcy Act or applicable State law or winding up or administration pursuant
to the insolvency laws of the United Kingdom, as applicable, the same percentage
of their respective claims, figured before crediting to the claim of the Trustee
anything on account of the receipt by it from the Company of the funds and
property in such special account and before crediting to the respective claims
of the Trustee and the Holders and the holders of other indenture securities
dividends on claims filed against the Company in bankruptcy or receivership or
in proceedings for reorganization pursuant to the Federal Bankruptcy Act or
applicable State law or winding up or administration pursuant to the insolvency
laws of the United Kingdom, as applicable, but after crediting thereon receipts
on account of the indebtedness represented by their respective claims from all
sources other than from such dividends and from the funds and property so held
in such special account.  As used in this paragraph, with respect to any claim,
the term "dividends" shall include any distribution with respect to such claim,
in bankruptcy or receivership or proceedings for reorganization pursuant to the
Federal Bankruptcy Act or applicable State law or winding up or administration
pursuant to the insolvency laws of the United Kingdom, as applicable, whether
such distribution is made in cash, securities or other property, but shall not
include any such distribution with respect to the secured portion, if any, of
such claim.

          Any Trustee which has resigned or been removed after the beginning of
such three months' period shall be subject to the provisions of this Subsection
as though such resignation or removal had not occurred.  If any Trustee has
resigned or been removed prior to the beginning of such three months' period, it
shall be subject to the provisions of this Subsection if and only if the
following conditions exist:

          (i)    the receipt of property or reduction of claim, which would have
     given rise to the obligation to account, if such Trustee had continued as
     Trustee, occurred after the beginning of such three months' period; and

          (ii)   such receipt of property or reduction of claim occurred within
     three months after such resignation or removal.

          (b)    There shall be excluded from the operation of Subsection (a) of
this Section 613 a creditor relationship arising from:

                                       51
<PAGE>
 
          (1)  the ownership or acquisition of securities issued under any
     indenture, or any security or securities having a maturity of one year or
     more at the time of acquisition by the Trustee;

          (2)  advances authorized by a receivership or bankruptcy court of
     competent jurisdiction or by this Indenture, for the purpose of preserving
     any property which shall at any time be subject to the lien of this
     Indenture or of discharging tax liens or other prior liens or encumbrances
     thereon, if notice of such advances and of the circumstances surrounding
     the making thereof is given to the Holders at the time and in the manner
     provided in this Indenture;

          (3)  disbursements made in the ordinary course of business in the
     capacity of trustee under an indenture, transfer agent, registrar,
     custodian, paying agent, fiscal agent or depository, or other similar
     capacity;

          (4)  an indebtedness created as a result of services rendered or
     premises rented; or an indebtedness created as a result of goods or
     securities sold in a cash transaction, as defined in Subsection (c) of this
     Section 613;

          (5)  the ownership of stock or of other securities of a corporation
     organized under the provisions of Section 25 (a) of the Federal Reserve
     Act, as amended, which is directly or indirectly a creditor of the Company;
     and

          (6)  the acquisition, ownership, acceptance or negotiation of any
     drafts, bills of exchange, acceptances or obligations which fall within the
     classification of self-liquidating paper, as defined in Subsection (c) of
     this Section 613.

          (c)  For the purposes of this Section 613 only:

               (1)  the term "default" means any failure to make payment in full
          of the principal of or interest on any of the Securities or upon the
          other indenture securities when and as such principal or interest
          becomes due and payable;

               (2)  the term "other indenture securities" means securities upon
          which the Company is an obligor (as defined in the Trust Indenture
          Act) outstanding under any other indenture (i) under which the Trustee
          is also trustee, (ii) which contains provisions substantially similar
          to the provisions of this Section 613, and (iii) under which a default
          exists at the time of the apportionment of the funds and property held
          in such special account;

               (3)  the term "cash transaction" means any transaction in which
          full payment for goods or securities sold is made within seven days
          after delivery of the goods or securities in currency or in checks or

               (4)  the term "self-liquidating paper" means any draft, bill of
          exchange, acceptance or obligation which is made, drawn, negotiated or
          incurred by the Company for the purpose of financing the purchase,

          or merchandise and which is secured by documents evidencing title to,
          possession of, or a lien upon, the goods, wares or merchandise or the
          receivables or proceeds arising from the sale of the goods, wares or
          merchandise previously constituting the 

                                       52
<PAGE>
 
          security, provided the security is received by the Trustee
          simultaneously with the creation of the creditor relationship with the
          Company arising from the making, drawing, negotiating or incurring of
          the draft, bill of exchange, acceptance or obligation;

               (5)  the term "Company" means any obligor upon the Securities;

SECTION 614.   Authenticating Agents
               ---------------------

          From time to time the Trustee, with the prior written approval of the
Company, may appoint one or more Authenticating Agents with respect to one or
more series of Securities with power to act on the Trustee's behalf and subject
to its direction in the authentication and delivery of Securities of such series
or in connection with transfers and exchanges under Sections 304, 305, 306, and
1104 as fully to all intents and purposes as though the Authenticating Agent had
been expressly authorized by those Sections of this Indenture to authenticate
and deliver Securities of such series. For all purposes of this Indenture, the
authentication and delivery of Securities by an Authenticating Agent pursuant to
this Section 614 shall be deemed to be authentication and delivery of such
Securities "by the Trustee". Each such Authenticating Agent shall be acceptable
to the Company and shall at all times be a corporation organized and doing
business under the laws of the United States, any State thereof or the District
of Columbia, authorized under such laws to exercise corporate trust powers,
having a combined capital and surplus of at least $50,000,000 and subject to
supervision or examination by Federal, State or District of Columbia authority.
If such corporation publishes reports of condition at leant annually pursuant to
law or the requirements of such authority, then for the purposes of this Section
614 the combined capital and surplus of such corporation shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time an Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section 614, such
Authenticating Agent shall resign immediately in the manner and with the effect
specified in this Section 614.

          Any corporation into which any Authenticating Agent may be merged or
with which it may be consolidated, or any corporation resulting from, any merger
or consolidation or to which any Authenticating Agent shall be a party, or any
corporation succeeding to the corporate trust business of any Authenticating
Agent, shall be the successor of the Authenticating Agent hereunder, if such
successor corporation is otherwise eligible under this Section 614, without the
execution or filing of any paper or any further act on the part of the parties
hereto or the Authenticating Agent or such successor corporation.

          An Authenticating Agent may resign at any time by giving written
notice of resignation to the Trustee and to the Company. The Trustee may at any
time terminate the agency of any Authenticating Agent by giving written notice
of termination to such Authenticating Agent and to the Company. Upon receiving
such a notice of resignation or upon such a termination, or in case at any time
any Authenticating Agent shall cease to be eligible under this Section 614, the
Trustee may appoint a successor Authenticating Agent with the prior written
approval of the Company and shall mail notice of such appointment to all Holders
of Securities of the series with respect to which such Authenticating Agent will
serve, as the names and addresses of such Holders appear on the Security
Register. Any successor Authenticating Agent, upon acceptance of its appointment
hereunder, shall become vested with 

                                       53
<PAGE>
 
all the rights, powers and duties of its predecessor hereunder, with like effect
as if originally named as an Authenticating Agent. No successor Authenticating
Agent shall be appointed unless eligible under the provisions of this Section
614.

          The Trustee agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section 614 as may be
agreed in a separate writing among the Company, the Trustee and such
Authenticating Agent, and the Trustee shall be entitled to be reimbursed for
such payments pursuant to Section 607.

          If an appointment with respect to one or more series of Securities is
made pursuant to this Section 614, the Securities of such series may have
endorsed thereon, in addition to the Trustee's certificate of authentication, an
alternate certificate of authentication in the following form:

          This is one of the Securities of the series designated herein referred
to in the within mentioned Indenture.

               HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

SECTION  701.  Company to Furnish Trustee Names and Addresses of Holders
               ---------------------------------------------------------

          The Company will furnish or cause to be furnished to the Trustee with
respect to the Registered Securities of each series

          (a)  semi-annually, not later than 15 days after each Regular Record
     Date, or, in the case of any series of Registered Securities on which semi-
     annual interest is not payable, not more than 15 days after such semi-
     annual dates as may be specified by the Trustee, a list, in such form as
     the Trustee may reasonably require, of the names and addresses of the
     Holders as of such Regular Record Date or semi-annual date, as the case may
     be, and

          (b)  at such other times as the Trustee may request in writing, within
     30 days after the receipt by the Company of any such request, a list of
     similar form and content as of a date not more than 15 days prior to the
     time such list is furnished;

                                       54
<PAGE>
 
provided, however, that if and so long as the Trustee is Security Registrar for
- --------  -------                                                              
any series of Registered Securities, no such list shall be required to be
furnished with respect to any such series.

SECTION 702.   Preservation of Information; Communications to Holders
               ------------------------------------------------------

          (a)  The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders contained in the most recent
list furnished to the Trustee as provided in Section 701 and the names and
addresses of Holders received by the Trustee in its capacity as Security
Registrar.  The Trustee may destroy any list furnished to it as provided in
Section 701 upon receipt of a new list so furnished.

          (b)  If three or more Holders (herein referred to as "applicants")
apply in writing to the Trustee, and furnish to the Trustee reasonable proof
that each such applicant has owned a Security for a period of at least six
months preceding the date of such application, and such application states that
the applicants desire to communicate with other Holders with respect to their
rights under this Indenture or under the Securities and is accompanied by a copy
of the form of proxy or other communication which such applicants propose to
transmit, then the Trustee shall, within five business days after the receipt of
such application, at its election, either

          (i)    afford such applicants access to the information preserved at
     the time by the Trustee in accordance with Section 702(a), or

          (ii)   inform such applicants as to the approximate number of Holders
     whose names and addresses appear in the information preserved at the time
     by the Trustee in accordance with Section 702(a), and as to the approximate
     cost of mailing to such Holders the form of proxy or other communication,
     if any, specified in such application.

          If the Trustee shall elect not to afford such applicants access to
such information, the Trustee shall, upon the written request of such
applicants, mail to each Holder whose name and address appear in the information
preserved at the time by the Trustee in accordance with Section 702(a) a copy of
the form of proxy or other communication which is specified in such request,
with reasonable promptness after a tender to the Trustee of the material to be
mailed and of payment, or provision for the payment, of the reasonable expenses
of mailing, unless within five days after such tender the Trustee shall mail to
such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of
the Trustee, such mailing would be contrary to the beat interest of the Holders
or would be in violation of applicable law. Such written statement shall specify
the basis of such opinion. If the Commission, after opportunity for a hearing
upon the objections specified in the written statement so filed, shall enter an
order refusing to sustain any of such objections or if, after the entry of an
order sustaining one or more of such objections, the Commission shall find,
after notice and opportunity for hearing, that all the objections so sustained
have been met and shall enter an order so declaring, the Trustee shall mail
copies of such material to all such Holders with reasonable promptness after the
entry of such order and the renewal of such tender; otherwise the Trustee shall
be relieved of any obligation or duty to such applicants respecting their
application.

          (c)  Every Holder of Securities, by receiving and holding the same,
agrees with the Company and the Trustee that neither the Company nor the Trustee
nor any agent of 

                                       55
<PAGE>
 
either of them shall be held accountable, by reason of the disclosure of any
such information as to the names and addresses of the Holders in accordance with
Section 702(b), regardless of the source from which such information was
derived, and that the Trustee shall not be held accountable by reason of mailing
any material pursuant to a request made under Section 702(b).

SECTION 703.   Reports by Trustee
               ------------------

          (a)  Within 60 days after ____ 1 of each year, commencing ____1, 1997,
the Trustee shall transmit by mail to all Holders of Securities a brief report
dated as of such ____ 1, of such year with respect to any of the following
events which may have occurred within the previous 12 months (but if no such
event has occurred within such period no report need be transmitted):

          (1)  any change to its eligibility under Section 609 and its
     qualifications under Section 608;

          (2)  the creation of or any material change to a relationship
     specified in Section 608;

     and for the reimbursement of which it claims or may claim a lien or charge,
     prior to that of the Securities, on any property or funds held or collected
     by it as Trustee, except that the Trustee shall not be required (but may
     elect) to report such advances if such advances so remaining unpaid
     aggregate not more than one-half of one percentum of the principal amount
     of the Securities outstanding on the date of such report;

          (4)  any change to the amount, interest rate and maturity date of all
     other indebtedness owing by the Company (or by any other obligor on the
     Securities) to the Trustee in its individual capacity, on the date of such
     report, with a brief description of any property held as collateral

SECTION 902.   Supplemental Indentures with Consent of Holders
               -----------------------------------------------

          With the consent of the Holders of a majority in aggregate principal

     Trustee" and concomitant changes in this Section 902, or the deletion of
     this proviso, in accordance with the requirements of Sections 611(b) and
     901(8).

A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Securities, or which modifies the
rights of the Holders of Securities of such series with respect to such covenant
or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

          It shall not be necessary for any Act of Holders under this Section
902 to approve the particular form of any proposed supplemental indenture, but

execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as

                                   COVENANTS

SECTION 1001. Payment of Principal, Premium, if any, and Interest
              ---------------------------------------------------

          The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of (and premium,
if any) and interest and Additional Amounts, if any, on the Securities of that
series in accordance with the terms of the Securities and this Indenture.  An
installment of principal of or interest on the Securities of a series shall be
considered paid on the date it is due if the Trustee or Paying Agent holds at
11:00 a.m. New York City time on that date money deposited by the Company in
immediately available funds and designated for, and sufficient to pay, the
installment in full.

          Neither the Company nor any agent of the Company will have any
responsibility or liability for any aspect relating to payments made or to be
made by the Book-Entry Depositary to DTC in respect of the Securities of a
series or the Book-Entry Interests.  None of the Company, the Trustee, the Book-
entry Depositary or any agent of any of the foregoing will have any
responsibility or liability for any aspect relating to payments made or to be
made by DTC on account of a Participant's or Indirect Participant's ownership of
an interest in the Book-Entry Interest or for maintaining, supervising or
reviewing any records relating to a Participant's interests in the Book-Entry
Interest.

SECTION 1002.  Maintenance of Office or Agency
               -------------------------------

          The Company will maintain (i) in the Borough of Manhattan, The City of
New York, an office or agency where Securities of any series may be presented or
surrendered for 

                                       61
<PAGE>
 
payment, and where notices and demands to or upon the Company in respect of the
Securities of such series and this Indenture may be served and if definitive
Registered Securities have been issued, an office or agency of a Transfer Agent
where Securities may be surrendered for registration of transfer or exchange,
and (ii) an office or agency of a Paying Agent where the Securities may be paid
in Luxembourg so long as the Securities are listed on the Luxembourg Stock
Exchange and the rules of such exchange so require.  The Company will give
prompt written notice to the Trustee of the location, and any change in the
location, of any such office or agency.  If at any time the Company shall fail
to maintain any such required office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and
demands may be made or served at the Corporate Trust Office of the Trustee,
except that Bearer Securities of that series pursuant to Section 1001 may be
presented at the place specified for the purpose pursuant to Section 301, and
the Company hereby appoints the Paying Agent as its agent to receive all such
presentations, surrenders, notices and demands.

          The Company may also from time to time designate one or more other
offices or agencies (in or outside of such Place of Payment) where the
Securities of one or more series and any appurtenant coupons (subject to Section
1001) may be presented or surrendered for any or all of such purposes, and may
from time to time rescind such designations; provided, however, that no such
                                             --------  -------              
designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in each Place of Payment for any
series of Securities for such purposes.  The Company will give prompt written
notice to the Trustee of any such designation and any change in the location of
any such other office or agency.  The Company will at all time maintain at least
one Paying Agent which is located outside the United Kingdom for each series of
Securities.

SECTION 1003.  Money for Securities Payments to Be Held in Trust
               -------------------------------------------------

          If the Company shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of (and premium, if any) or interest, if any, on any of the Securities
of that series, segregate and hold in trust for the benefit of the Persons
entitled thereto a sum sufficient to pay the principal (and premium, if any) or
interest, if any, so becoming due until such sums shall be paid to such Persons
or otherwise disposed of as herein provided and will promptly notify the Trustee
of its action or failure so to act.

          Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, no later than 10:00 a.m., New York Time, on or
prior to each due date of the principal of (and premium, if any) or interest, if
any, on any Securities of that series, deposit with a Paying Agent a sum in
immediately available funds sufficient to pay the principal and premium, if any)
or interest so becoming due, such sum to be held in trust for the benefit of the
Persons entitled to such principal, premium or interest.

          The Company will cause each Paying Agent for any series of Securities
other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section 1003, that such Paying Agent will:

          (1)  hold all sums held by it for the payment of the principal of (and
     premium, if any) or interest, if any, on Securities of that series in trust
     for the benefit 

                                       62
<PAGE>
 
     of the Persons entitled thereto until such sums shall be paid to such
     Persons or otherwise disposed of as herein provided;

          (2)  give the Trustee notice of any default by the Company (or any
     other obligor upon the Securities of that series) in the making of any
     payment of principal (and premium, if any) or interest, if any, on the
     Securities of that series; and

          (3)  at any time during the continuance of any such default, upon the
     written request of the Trustee, forthwith pay to the Trustee all sums so
     held in trust by such Paying Agent.

          The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by the Company or by any Paying Agent
to the Trustee, the Company or such Paying Agent, as the case may be, shall be
released from all further liability with respect to such money.

          Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of (and premium, if
any) or interest, if any, on any Security of any series and remaining unclaimed
for two years after such principal (and premium, if any) or interest has become
due and payable shall be paid to the Company on Company Request, or (if then
held by the Company) shall be discharged from such trust; and the Holder of such
Security shall thereafter, as an unsecured general creditor, look only to the
Company for payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the Company as
trustee thereof, shall thereupon cease. 

SECTION 1004.  Limitation on Liens
               -------------------

     If this covenant shall be made applicable to the Securities of a particular
series, neither the Company nor any Significant Subsidiary shall issue, assume
or guarantee any notes, bonds, debentures or other similar evidences of
indebtedness, in each case for money borrowed ("Debt"), secured by a Lien upon
any property or assets (other than cash) without effectively providing that the
outstanding Securities (together with, if the Company so determines, any other
indebtedness or obligation then existing or thereafter created ranking equally
with such Securities) shall be secured equally and ratably with (or prior to)
such Debt so long as such Debt shall be so secured.  The foregoing restriction
on Liens will not, however, apply to:

          (a)  Liens in existence on the date of original issue of such
     Securities;

          (b)  (i) any Lien created or arising over any property which is
     acquired, constructed or created by the Company or any of its Significant
     Subsidiaries, but only if (A) such Lien secures only principal amounts (not
     exceeding the cost of such acquisition, construction or creation) raised
     for the purposes of such acquisition, construction or creation, together
     with any costs, expenses, interest and fees incurred in relation thereto or
     a guarantee given in respect thereof, (B) such Lien is created or arises on
     or before 90 days after the completion of such acquisition, construction or
     creation and (C) such Lien is confined solely to the property so acquired,
     constructed or created; or (ii) any Lien to secure indebtedness for
     borrowed money incurred in 

                                       63
<PAGE>
 
     connection with a specifically identifiable project where the Lien relates
     to a property (including, without limitation, shares or other rights of
     ownership in the entity(ies) which own such property or project) involved
     in such project and acquired by the Company or a Significant Subsidiary
     after the date of original issue of the Securities and the recourse of the
     creditors in respect of such indebtedness is limited to any or all of such
     project and property (including as aforesaid);

          (c)  any Lien securing amounts not more than 90 days overdue or
     otherwise being contested in good faith;

          (d)  (i) rights of financial institutions to offset credit balances in
     connection with the operation of cash management programs established for
     the benefit of the Company and/or a Significant Subsidiary or in connection
     with the issuance of letters of credit for the benefit of the Company
     and/or a Significant Subsidiary; (ii) any Lien securing indebtedness of the
     Company and/or a Significant Subsidiary for borrowed money incurred in
     connection with the financing of accounts receivable; (iii) any Lien
     incurred or deposits made in the ordinary course of business, including,
     but not limited to, (A) any mechanics', materialmens', carriers',
     workmens', vendors' or other like Liens and (B) any Liens securing amounts
     in connection with workers' compensation, unemployment insurance and other
     types of social security; (iv) any Lien upon specific items of inventory or
     other goods and proceeds of the Company and/or a Significant Subsidiary
     securing obligations of the Company and/or a Significant Subsidiary in
     respect of bankers' acceptances issued or created for the account of such
     person to facilitate the purchase, shipment or storage of such inventory or
     other goods; (v) any Lien incurred or deposits made securing the
     performance of tenders, bids, leases, trade contracts (other than for
     borrowed money), statutory obligations, surety bonds, appeal bonds,
     government contracts, performance bonds, return-of-money bonds and other
     obligations of like nature incurred in the ordinary course of business;
     (vi) any Lien created by the Company or a Significant Subsidiary under or
     in connection with or arising out of any pooling and settlement agreements
     or pooling and settlement arrangements of the electricity industry or any
     transactions or arrangements entered into in connection with hedging or
     management of risks relating to the electricity industry; (vii) any Lien
     constituted by a right of set off or right over a margin call account or

     corporation); (ii) any Lien on any property or assets existing at the time
     of acquisition thereof and which is not created in anticipation of such
     acquisition (unless such Lien was created to secure or provide for the
     payment of any part of the purchase price of such property or assets); and
     (iii) any Lien created or outstanding on or over any asset of any company
     which becomes a Significant Subsidiary on or after the date of the issuance
     of such Securities where such Lien is created prior to the date on which
     such company becomes a Significant Subsidiary;

          (g)  Liens required by any contract or statute in order to permit the
     Company or a Significant Subsidiary to perform any contract or subcontract

     Subsidiary; and (iii) any Lien securing taxes or assessments or other
     applicable governmental charges or levies;

          (h)  (i) any Lien which arises pursuant to any order of attachment,
     distraint or similar legal process arising in connection with court
     proceedings and any Lien which secures the reimbursement obligation for any
     bond obtained in connection with an appeal taken in any court proceeding,
     so long as the execution or other enforcement of such Lien arising pursuant
     to such legal process is effectively stayed and the claims secured thereby
     are being contested in good faith and, if appropriate, by appropriate legal
     proceedings, or any Lien in favor of a plaintiff or defendant in any action
     before a court or tribunal as security for costs and/or other expenses; or

     Notwithstanding the foregoing, the Company and/or a Significant Subsidiary
may create or permit to subsist Liens over any property or assets , so long as
the aggregate amount of Debt secured by all such Liens (excluding therefrom the
amount of Debt secured by Liens set forth in clauses (a) through (i), inclusive,
above) does not exceed 10% of the Consolidated Net Tangible Assets.

     Nothing contained in this Indenture in any way restricts or prevents the
Company or any Subsidiary from incurring any indebtedness.

SECTION 1005.  Limitation on Sale and Lease-Back Transactions
               ----------------------------------------------

          If this covenant shall be made applicable to the Securities of a
particular series, the Company covenants and agrees that so long as any
Securities of such series remains 

                                       65

outstanding neither it nor any Significant Subsidiary will enter into any
arrangement with any person (other than the Company or a Significant
Subsidiary), providing for the leasing to the Company or a Significant
Subsidiary of any assets which have been or are to be sold or transferred by the
Company or such Significant Subsidiary to such person (a "Sale and Lease-Back
Transaction") unless; (i) such transaction involves a lease for a temporary
period not to exceed three years; (ii) such transaction is between the Company
or a Significant Subsidiary and an affiliate of the Company; (iii) the Company
would be entitled to incur indebtedness secured by a Lien on the assets or
property involved in such transaction at least equal in amount to the
attributable debt with respect to such Sale and Lease-Back Transaction, without
equally and ratably securing the Securities, pursuant to the limitation on Liens
described above other than pursuant to the penultimate paragraph thereof; (iv)
such transaction is entered into within 60 days after the initial acquisition by
the Company of the assets or property subject to such transaction; (v) after
giving effect thereto, the aggregate amount of all attributable debt with
respect to all such Sale and Lease-Back Transactions does not exceed 10% of
Consolidated Net Tangible Assets; or (vi) the Company or a Significant
Subsidiary within the twelve months preceding the sale or transfer or the twelve
months following the sale or transfer, regardless of whether such sale or
transfer may have been made by the Company or such Significant Subsidiary,
applies in the case of a sale or transfer for cash, an amount equal to the net
proceeds thereof and, in the case of a sale or transfer otherwise than for cash,
an amount equal to the fair value of the assets so leased at the time of
entering into such arrangement (as determined by the Board of Directors of the
Company or such Significant Subsidiary), (a) to the retirement of indebtedness
for money borrowed, incurred or assumed by the Company or a Significant
Subsidiary, which by its terms matures at, or is extendible or renewable at the
option of the obligor to, a date more than twelve months after the date of
incurring, assuming or guaranteeing such debt or (b) to investment in any assets
of the Company or any Significant Subsidiary.

SECTION 1006.  Statement by Officers as to Default
               -----------------------------------

          The Company will deliver to the Trustee within 120 days after the end
of each fiscal year of the Company a certificate from the principal executive,
financial or accounting officer of the Company, stating that in the course of
the performance by such signer of his duties as an officer of the Company he
would normally have knowledge of any default by the Company in the performance
and observance of any of the covenants contained in Sections 1001 to 1008,
stating whether or not he has knowledge of any such default without regard to

default of which such signer has knowledge and the nature thereof.

SECTION 1007.  Modification or Waiver of Certain Covenants
               -------------------------------------------

          The Company may omit in any particular instance to comply with any
term, provision or condition set forth in this Indenture with respect to the
Securities of any series if before the time for such compliance the Holders of
at least a majority in aggregate principal amount of the Outstanding Securities
of such series shall, by Act of such Holders, either modify the covenant or
waive such compliance in such instance or generally waive compliance with such
term, provision or condition, provided that no such modification shall without
the consent of each Holder (a) change the stated maturity upon which the
principal of or the interest on the Securities is due and payable, (b) reduce
the principal amount thereof or the rate of interest thereon, (c) change any
obligation of the Company to pay Additional Amounts, (d) change any place of
payment or the currency in which, the Securities or any premium or the interest

redemption, on or after redemption date) or (f) reduce the percentage in
principal amount of the outstanding Securities, the consent of whose Holders is
required for any waiver of compliance with certain provisions of the Indenture
or certain defaults hereunder and their consequences provided for in the
Indenture.  The Securities owned by the Company or any of its Affiliates shall
be deemed not to be outstanding for, among other purposes, consenting to any
such modification.

SECTION 1008.  Further Assurances.
               ------------------ 

          The Company and the Trustee shall execute and deliver all such other
documents, instruments and agreements and do all such other acts and things as
may be reasonably required to enable the Trustee to exercise and enforce its
rights under this Indenture and under the documents, instruments and agreements
required under this Indenture and to carry out the intent of this Indenture.

SECTION 1009.  Payment of Additional Amounts
               -----------------------------

          If the Securities of a particular series provide for payment of
Additional Amounts, all payments of principal and interest (including payments
of discount and premium, if any) in respect of the Securities of such series
shall be made free and clear of, and without withholding or deduction for or on
account, of any present or future taxes, duties, assessments or governmental
charges of whatever nature imposed, levied, collected, withheld or assessed by
or within the United Kingdom or by or within any political subdivision thereof
or any authority therein or thereof having power to tax ("United Kingdom
Taxes"), unless such withholding or deduction is required by law.  In that event
the Company shall pay to the Holder such additional amounts ("Additional
Amounts") as will result in the payment to such Holder of the amount that would
otherwise have been receivable by such Holder in the absence of such withholding
or deduction, except that no such Additional Amounts shall be payable:

          (a)  to, or to a Person on behalf of, a Holder who is liable for such
     United Kingdom Taxes in respect of Securities, by reason of such Holder
     having some connection with the United Kingdom (including being a citizen
     or resident or national of, or carrying on a business or maintaining a
     permanent establishment in, or being physically present in, the United
     Kingdom) other than the mere holding of a Security or the receipt of
     principal and interest (including payments of discount and premium, if any)
     in respect thereof; or

          (b)  to, or to a Person on behalf of, a Holder who presents a Security
     (where presentation is required) for payment more than 30 days after the
     Relevant Date except to the extent that such Holder would have been
     entitled to such Additional Amounts on presenting such Security for payment
     on the last day of such period of 30 days;

          (c)  to, or to a Person on behalf of, a Holder who presents a Security
     (where presentation is required) in the United Kingdom;

          (d)  to, or to a Person on behalf of, a Holder who would not be liable
     or subject to the withholding or deduction by making a declaration of non-
     residence or similar claim for exemption to the relevant tax authority; or

          (e)  to, or to a Person on behalf of, a Holder of a definitive
     Registered Security issued pursuant to the request of owners representing a
     majority in outstanding 

                                       67
<PAGE>
 
     principal amount in the Book-Entry Interest following and during the
     continuance of an Event of Default if such Holder (or any predecessor
     Holder) was one of such owners requesting that definitive Registered
     Securities be so issued.

          Such Additional Amounts will also not be payable where, had the
beneficial owner of the Security (or any interest therein) been the Holder of
the Security, he would not have been entitled to payment of Additional Amounts
by reason of any one or more of clauses (a) through (e) above.  If the Company
shall determine that Additional Amounts will not be payable because of the
immediately preceding sentence, the Company will inform such Holder promptly
after making such determination setting forth the reason(s) therefor.

          Reference to principal, interest, discount or premium in respect of
the Securities shall be deemed also to refer to any Additional Amounts which may
be payable as set forth in this Indenture or in the Securities.

          At least 10 Business Days prior to the first Interest Payment Date
(and at least 10 Business Days prior to each succeeding Interest Payment Date if
there has been any change with respect to the matters set forth in the below-
mentioned Officers' Certificate) the Company will furnish to the Trustee and the
Paying Agents an Officers' Certificate instructing the Trustee and the Paying
Agents whether payments of principal of or interest on the Securities due on
such Interest Payment Date shall be without deduction or withholding for or on
account of any United Kingdom Taxes.  If any such deduction or withholding shall
be required, prior to such Interest Payment Date the Company will furnish the
Trustee and the Paying Agents with an Officers' Certificate which specifies the
amount, if any, required to be withheld on such payment to Holders and certifies
that the Company shall pay such withholding or deduction.  The Company covenants
to indemnify the Trustee for, and to hold the Trustee harmless against, any
loss, liability or expense reasonably incurred without negligence, willful
misconduct or bad faith on their part, arising out of or in connection with
actions taken or omitted by the Trustee in reliance on any Officers' Certificate
furnished pursuant to this paragraph.  Any Officers' Certificate required by
this Section 1009 to be provided to the Trustee and any Paying Agent shall be
deemed to be duly provided if telecopied to the Trustee and such Paying Agent.

          The Company shall furnish to the Trustee the official receipts (or a
certified copy of the official receipts) evidencing payment of United Kingdom
Taxes.  Copies of such receipts shall be made available to the Holders of the
Securities upon request.

SECTION 1010.  Copies Available to Holders.
               --------------------------- 

          Copies of this Indenture shall be available for inspection by the
Holders on a Business Day during normal business hours at the principal office
of the Company and at the Corporate Trust Office. In addition, if the Securities
of any series are listed on the London Stock Exchange, the Luxembourg Stock
Exchange or any other stock exchange located outside the United States and such
stock exchange shall so require, copies of this Indenture, the Deposit
Agreement, the DTC Agreement, the memorandum and articles of association of the
Company and the most recent publicly available annual report of the Company
shall be made available for inspection by the Holders of such Securities on a
Business Day during normal business hours at the offices of the paying agents
and at the office of the listing agent required to be maintained by such
exchange for so long as the Securities of such series are outstanding and are
listed on such stock exchange.

SECTION  1101. Applicability of Article
               ------------------------

          Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as

SECTION 1102.  Election to Redeem; Notice to Trustee
               -------------------------------------

          The election of the Company to redeem any Securities shall be
authorized by a Board of Directors resolution and evidenced by an Officers'
Certificate.  In case of any redemption at the election of the Company of less

to the Redemption Date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such Redemption Date and of
the principal amount of Securities of such series to be redeemed.  In the case
of any redemption of Securities prior to the expiration of any restriction on
such redemption provided in the terms of such Securities or elsewhere in this
Indenture, or pursuant to an election by the Company which is subject to a
condition specified in the terms of such Securities or elsewhere in this
Indenture, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction or condition.

SECTION 1103.  Selection by Trustee of Securities to Be Redeemed
               -------------------------------------------------

          If less than all the Securities of any series are to be redeemed, the
particular securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of portions equal to the minimum authorized denomination for
Securities of that series (or any integral multiple thereof) of the principal
amount of Securities of such series of a denomination larger than the minimum
authorized denomination for Securities of that series.

          Securities shall be excluded from eligibility for selection for
redemption if they are identified by certificate number in a written statement
signed by an authorized officer of the Company and delivered to the Security
Registrar at least 30 days prior to the Redemption Date as being owned of record
and beneficially by, and not pledged or hypothecated by either (a) the Company
or (b) an entity specifically identified in such written statement which is an
Affiliate of the Company.

          The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption and, in the case of any Securities selected
for partial redemption, the principal amount thereof to be redeemed.

          For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Securities 

                                       69
<PAGE>
 
redeemed or to be redeemed only in part, to the portion of the principal amount
of such Securities which has been or is to be redeemed.

SECTION 1104.  Notice of Redemption
               --------------------

          Notice of redemption shall be given not less than 15 days nor more

          All notices of redemption shall state:

          (1)  the Redemption Date,

          (2)  the Redemption Price,

          (3)  if less than all the Outstanding Securities of any series are to
     be redeemed, the identification (and, in the case of partial redemption,
     the principal amounts) of the particular Securities to be redeemed,

          (4)  that on the Redemption Date the Redemption Price will become due
     and payable upon each such Security to be redeemed and, if applicable, that
     interest thereon will cease to accrue on and after said date,

          (5)  the place or places where such Securities are to be surrendered
     for payment of the Redemption Price, and

          (6)  that the redemption is for a sinking fund, if such is the case.

          Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

SECTION 1105.  Deposit of Redemption Price
               ---------------------------

          On or prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Principal Paying Agent (or, if the Company is acting as its
own Paying Agent, segregate and hold in trust as provided in Section 1003) an
amount of money sufficient to pay the Redemption Price of, and (except if the
Redemption Date shall be an Interest Payment Date) accrued interest on, all the
Securities which are to be redeemed on that date (to the extent that such
amounts are not already on deposit at such time in accordance with the
provisions of Sections 401, 403 or 1007).

SECTION 1106.  Securities Payable on Redemption Date
               -------------------------------------

          Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued and
unpaid interest) such Securities shall cease to bear interest.  Upon surrender
of any such Security for redemption in accordance with said notice, such
Security shall be paid by the Company at the Redemption Price, together with
accrued and unpaid interest to the Redemption Date; provided, however, that
                                                    --------  -------

<PAGE>
 
Holders of such Securities, or one or more Predecessor Securities, and in the
case of Registered Securities, registered as such at the close of business on
the relevant Record Dates according to their terms and the provisions of Section
307.

          If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate prescribed
therefor in the Security.

SECTION 1107.  Securities Redeemed in Part
               ---------------------------

          Any Security (including any Global Security) which is to be redeemed
only in part shall be surrendered at a Place of Payment therefor (with, if the
Company or the Trustee so requires, due endorsement by, or a written instrument
of transfer in form satisfactory to the Company and the Trustee duly executed
by, the Holder thereof or his attorney duly authorized in writing), and the
Company shall execute, and the Trustee upon written direction shall authenticate
and deliver to the Holder of such Security without service charge, a new
Security or Securities of the same series, of any authorized denomination as
requested by such Holder, in aggregate principal amount equal to and in exchange
for the unredeemed portion of the principal of the security so surrendered;
provided, that if a Global Security is so surrendered, the new Global Security
- --------                                                                      
shall be in a denomination equal to the unredeemed portion of the principal of
the Global Security so surrendered.

SECTION 1108.  Optional Redemption in the Event of Change in United Kingdom Tax
               ----------------------------------------------------------------
               Treatment
               ---------

          The Securities of any series may be redeemed at the election of the
Company, as a whole, but not in part, by the giving of notice as provided in
Section 1104, at a price equal to the outstanding principal amount thereof,
together with Additional Amounts, if any, and accrued interest, if any, to the
Redemption Date, if (a) the Company satisfies the Trustee that it has or will
become obligated to pay Additional Amounts on the Securities of such series, as
a result of either (x) any change in, or amendment to, the laws or regulations
of the United Kingdom or any political subdivision or any authority or agency
thereof or therein having power to tax or levy duties, or any change in the
application or interpretation of such laws or regulations, which change or
amendment becomes effective on or after the date  of the relevant underwriting
agreement for the Securities of such series, or (y) the issuance of definitive
Registered Securities as the result of DTC having notified the Company and the
Book-Entry Depositary that it is unable or unwilling to continue to hold the
Book-Entry Interest or at any time ceasing to be a "clearing agency" registered
as such under the Exchange Act and, in either case, a successor not being
appointed by the Company within 120 days or the Book-entry Depositary notifying
the Company that it is unwilling or unable to continue as Book-Entry Depositary
with respect to the Securities of such series and a successor Book-Entry
Depositary not being appointed being within 120 days or there having occurred
and being continuing an Event of Default with respect to the Securities of such
series and the Holder, in such circumstances, having requested in writing a
definitive Registered Security, and (b) such obligation cannot be avoided by the
Company taking reasonable measures available to it; provided, however, that no
                                                    --------  -------         
such notice of redemption shall be given earlier than 90 days prior to the
earliest date on which the Company would be obligated to pay such Additional
Amounts, were a payment in respect of the Securities then due.  Prior to the
giving of notice of redemption of such Securities pursuant to this Indenture,
the Company will deliver to the Trustee an Officers' Certificate stating that
the obligation to pay such Additional Amounts cannot be avoided by the Company
taking reasonable measures available to it, and 

                                       71
<PAGE>
 
the Trustee shall accept such certificate as sufficient evidence of such
condition, and such certificate shall be conclusive and binding on the Holders
of the Securities of such series.

               ------------------------

          The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of a series except as otherwise specified as
contemplated by Section 301 for Securities of such series.

          The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment", and any payment in excess of such minimum amount provided for by
the terms of Securities of any series is herein referred to as an "optional
sinking fund payment".  If provided for by the terms of Securities of any
series, the cash amount of any sinking fund payment may be subject to reduction
as provided in Section 1202.  Each sinking fund payment shall be applied to the
redemption of Securities of any series as provided for by the terms of
Securities of such series.

SECTION 1202.  Satisfaction of Sinking Fund Payments with Securities
               -----------------------------------------------------

          In lieu of making all or any part of any mandatory sinking fund
payment with respect to any series of Securities in cash, the Company may at its
option (a) deliver to the Trustee Securities of such series theretofore
purchased or otherwise acquired (except upon redemption pursuant to the
mandatory sinking fund) by the Company or receive credit for Securities of such
series (not previously so credited) theretofore purchased or otherwise acquired
(except as aforesaid) by the Company and delivered to the Trustee for
cancellation pursuant to Section 310, (b) receive credit for optional sinking
fund payments (not previously so credited) made pursuant to this Section 1202,
or (c) receive credit for Securities of such series (not previously so credited)
redeemed by the Company through any optional redemption provision contained in

or credited by the Trustee at the sinking fund Redemption Price specified in
such Securities.

SECTION 1203.  Redemption of Securities for Sinking Fund
               -----------------------------------------

          Not less than 30 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying (a) the amount of the next ensuing sinking fund payment
for that series pursuant to the terms of that series, (b) whether or not the
Company intends to exercise its right, if any, to make an optional sinking fund

or before any such 30th day, to deliver such written statement and Securities
specified in this paragraph, if any, shall not constitute a default but shall
constitute, on and as of such date, the irrevocable election of the Company (i)
that the mandatory sinking fund payment for such series due on the next
succeeding sinking fund payment date shall be paid entirely in cash without the
option to deliver or credit Securities of such series in respect therefor and
(ii) that the Company will make no optional sinking fund payment with respect to
such series as provided in this Section 1203.

          Not less than [30] days before each such sinking fund payment date the
Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 1103 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company
in the manner provided in Section 1104.  Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 1105, 1106 and 1107.

          The Trustee shall not redeem or cause to be redeemed any Security of a
series with sinking fund moneys or mail any notice of redemption of Securities
of such series by operation of the sinking fund during the continuance of a
default in payment of interest with respect to Securities of that series or an
Event of Default with respect to the Securities of that series except that,
where the mailing of notice of redemption of any Securities shall theretofore
have been made, the Trustee shall redeem or cause to be redeemed such
Securities, provided that it shall have received from the Company a sum
sufficient for such redemption.  Except as aforesaid, any moneys in the sinking
fund for such series at the time when any such default or Event of Default,
shall occur, and any moneys thereafter paid into the sinking fund, shall, during
the continuance of such default or Event of Default, be deemed to have been
collected under Article Five and held for the payment of all such Securities.
In case such Event of Default shall have been waived as provided in Section 513
or the default or Event of Default cured on or before the 30th day preceding the
sinking fund payment date, such moneys shall thereafter be applied on the next
succeeding sinking fund payment date in accordance with this Section 1203 to the
redemption of such Securities.

SECTION  1401. Consent to Jurisdiction; Appointment of Agent to Accept Service
               ---------------------------------------------------------------
               of Process
               ----------

          (a)  The Company irrevocably consents and agrees, for the benefit of
the Holders from time to time of the Securities and the Trustee, that any legal
action, suit or proceeding against it with respect to its obligations,
liabilities or any other matter arising out of or in connection with this
Indenture or the Securities may be brought in the Supreme Court of New York, New
York County or the United States District Court for the Southern District of New
York and any appellate court from either thereof and, until amounts due and to
become due in respect of the Securities have been paid, hereby irrevocably
consents and submits to the non exclusive jurisdiction of each such court in
personam, generally and unconditionally with respect to any action, suit or
proceeding for itself and in respect of its properties, assets and revenues.

          (b)  The Company has irrevocably designated, appointed, and empowered
[CT Corporation,] as its designee, appointee and agent to receive, accept and
acknowledge for and on its behalf, and its properties, assets and revenues,
service of any and all legal process, summons, notices and documents which may
be served in any action, suit or proceeding brought against the Company in any
United States or State court.  If for any reason such designee, appointee and
agent hereunder shall cease to be available to act as such, the Company agrees
to designate a new designee, appointee and agent in the Borough of 

                                       75
<PAGE>
 
Manhattan, The City of New York on the terms and for the purposes of this
Section 1301 satisfactory to the Trustee.  The Company further hereby
irrevocably consents and agrees to the service of any and all legal process,
summons, notices and documents in any action, suit or proceeding against the
Company by serving a copy thereof upon the relevant agent for service of process
referred to in this Section 1301 (whether or not the appointment of such agent
shall for any reason prove to be ineffective or such agent shall accept or
acknowledge such service) or by mailing copies thereof by registered or
certified air mail, postage prepaid, to the Company at its address specified in
or designated pursuant to this Indenture.  The Company agrees that the failure
of any such designee, appointee and agent to give any notice of such service to
it shall not impair or affect in any way the validity of such service or any
judgment rendered in any action or proceeding based thereon.  Nothing herein
shall in any way be deemed to limit the ability of the holders of the Securities
and the Trustee, to serve any such legal process, summons, notices and documents
in any other manner permitted by applicable law or to obtain jurisdiction over
the Company or bring actions, suits or proceedings against the Company in such
other jurisdictions, and in such manner, as may be permitted by applicable law.
The Company irrevocably and unconditionally waives, to the fullest extent
permitted by law, any objection which it may now or hereafter have to the laying
of venue of any of the aforesaid actions, suits or proceedings arising out of or
in connection with this Indenture brought in the Supreme Court of New York, New
York County or the United States District Court for the Southern District of New
York and any appellate court from either thereof and hereby further irrevocably
and unconditionally waives and agrees not to plead or claim in any such court
that any such action, suit or proceeding brought in any such court has been
brought in an inconvenient forum.

          If for the purpose of obtaining judgment in any court it is necessary
to convert a sum due hereunder to the holder of any Security from U.S. dollars
into another currency, the Company has agreed, and each holder by holding such
Security will be deemed to have agreed, to the fullest extent that they may
effectively do so, that the rate of exchange used shall be that at which in
accordance with normal banking procedures such Holder could purchase U.S.
dollars with such other currency in The City of New York on the Business Day
preceding the day on which final judgment is given.

          The obligation of the Company in respect of any sum payable by it to
the holder of a Security shall, notwithstanding any judgment in a currency (the
"judgment currency") other than U.S. dollars, be discharged only to the extent
that on the Business Day following receipt by the Holder of such security of any
sum, adjudged to be so due in the judgment currency, the Holder of such Security
may in accordance with normal banking procedures purchase U.S. dollars with the
judgment currency; if the amount of U.S. dollars so purchased is less than the
sum originally due to the holder of such Security in the judgment currency
(determined in the manner set forth in the preceding paragraph), the Company
agrees, as a separate obligation and notwithstanding any such judgment, to
indemnify the Holder of such Security against such loss, and if the amount of
the U.S. dollars so purchased exceeds the sum originally due to the Holder of
such Security, such Holder agrees to remit to the Company such excess, provided
that such Holder shall have no obligation to remit any such excess as long as
the Company shall have failed to pay such Holder any obligations due and payable
under such Security, in which case such excess may be applied to such
obligations of the Company under such Security in accordance with the terms
thereof.

     Such Additional Amounts will also not be payable where, had the beneficial
owner of the Security (or any interest therein) been the Holder of the Security,
he would not have been entitled to payment of Additional Amounts by reason of

sentence, the Company will inform such Holder promptly after making such
determination setting forth the reason(s) therefor.

such payment first becomes due and (ii) if the full amount payable has not been
received in The City of New York by the Trustee or the bearer on or prior to
such due date, the date on which, the full amount having been so received,
notice to that effect shall have been given to the bearer hereof in accordance
with the Indenture.

          References to principal, interest, discount or premium in respect of
this Security shall be deemed also to refer to any Additional Amounts which may
be payable as set forth in the Indenture or in this Security.

          The Company shall furnish to the Trustee the official receipts (or a
certified copy of the official receipts) evidencing payment of United Kingdom
Taxes. Copies of such receipts shall be made available to the Holder of this
Security upon request.

Stock Exchange and the rules of the Luxembourg Stock Exchange so require,
notices to Holders of Securities of this series will be published in a leading
newspaper having general circulation in Luxembourg (which is expected to be the
Luxemburger Wort).

HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE.

the Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

                          ___% Senior Notes Due 2006


          This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or more
series under an Indenture, dated as of ________ __, 1996 (herein called the
"Original Indenture"), among the Company, Bankers Trust Company, as trustee

Indenture, dated as of _________ __, 1996 (together with the Original Indenture,
the "Indenture"), among the Company, the Trustee and the Paying and Transfer
Agent to which Indenture and all indentures supplemental thereto reference is
hereby made for a statement of the respective rights, limitations of rights,
duties and immunities thereunder of the Company, the Trustee the Paying and
Transfer Agent and the Holders of the Securities and of the terms upon which the
Securities are, and are to be, authenticated and delivered. This Security is one
of the series designated on the face hereof, limited in aggregate principal
amount to $________________.

          The Securities of this series will be redeemable in whole or in part,
at the option of the Company at any time, at a redemption price equal to the
greater of (i) 100% of the principal amount of the Securities of this series
being redeemed or (ii) the sum of the present values of the remaining scheduled
payments of principal of and interest on the Securities of this series being
redeemed discounted to the date of redemption on a semi-annual basis (assuming a
360-day year consisting of twelve 30-day months) at a discount rate equal to the
Treasury Yield plus __________ basis points, plus, for (i) or (ii) above,
whichever is applicable, accrued interest on the Securities of this series to
the date of redemption.

          "Treasury Yield" means, with respect to any redemption date, the rate
per annum equal to the semiannual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as
a percentage of its principal amount) equal to the Comparable Treasury Price for
such redemption date.

          "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term of such Securities of this series to be redeemed that would
be utilized, at the time of selection and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable
maturity to the remaining term of the Securities of this series.

                                       11
<PAGE>
 
          "Comparable Treasury Price" means, with respect to any redemption
date, (i) the average of the bid and asked prices for the Comparable Treasury
Issue (expressed in each case as a percentage of its principal amount) on the
third Business Day in New York City preceding such redemption date, as set forth
in the daily statistical release (or any successor release) published by the
Federal Reserve Bank of New York and designated "Composite 3:30 p.m. Quotations
for US Government Securities" or (ii) if such release (or any successor release)
is not published or does not contain such prices on such business day, the
Reference Treasury Dealer Quotation for such redemption date.

banking institution of national standing appointed by the Company and reasonably
acceptable to the Trustee.

          "Reference Treasury Dealer Quotation" means, with respect to the
Reference Treasury Dealer and any redemption date, the average, as determined by
the Trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount and quoted in
writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the
third business day preceding such redemption date).

          "Reference Treasury Dealer" means a primary US Government securities
dealer in New York City appointed by the Company and reasonably acceptable to
the Trustee.

          Notice of redemption shall be given as provided in the Indenture not
less than 15 days nor more than 30 days prior to the date fixed for redemption.

          If fewer than all the Securities of this series are to be redeemed,
selection of Securities of this series for redemption will be made by the
Trustee in any manner the Trustee deems fair and appropriate and that complies
with applicable legal and securities exchange requirements.

          Unless the Company defaults in payment of the redemption price, from
and after the redemption date, the Securities of this series or portions thereof
called for redemption will cease to bear interest, and the Holders thereof will
have no right in respect to such Securities of this series except the right to
receive the redemption price thereof.

          In the event of redemption of this Security in part only, a new
Security of this series and of like tenor for the unredeemed portion hereof will
be issued to the Holder hereof upon the cancellation hereof.

          The Indenture contains provisions for defeasance of (a) the entire
indebtedness of this Security and (b) certain restrictive covenants upon
compliance by the Company with certain conditions set forth therein.

          If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture. At any time after such declaration of acceleration with respect to
Securities of any series has been made, but before a judgment or decree for
payment of money has been obtained by the Trustee as provided in the Indenture,
if all Events of Default with respect to Securities of this series have been
cured or waived (other than the non-payment of principal of the Securities which
has become due solely by reason of such declaration of acceleration) then such
declaration of acceleration and its consequences shall be automatically annulled
and rescinded.

          The Securities of this Series are subject to redemption in whole but
not in part upon not less than 15 nor more than 30 days' notice given as
provided in the Indenture, at a price equal to the outstanding principal amount
thereof, together with Additional Amounts, if any, and accrued interest, if any,
to the Redemption Date if, (a) the Company satisfies the Trustee prior to the
giving of such notice that it has or will become obliged to pay Additional
Amounts as a result of either (x) any change in, or amendment to, the laws or
regulations of the United Kingdom or any political subdivision or any authority
or agency thereof or therein having power to tax or levy duties, or any change
in the application or interpretation of such laws or regulations, which change
or amendment becomes effective on or after the [date of the underwriting
agreement with respect to the Securities of the series,] or (y) the issuance of
Definitive Registered Securities pursuant to any of clauses (a), (b) or (d) of
the third following paragraph and (b) such obligation cannot be avoided by the
Company taking reasonable measures available to it, subject, as provided in the
Indenture, to the delivery by the Company of an Officers' Certificate stating
that such obligation to pay Additional Amounts cannot be avoided by the Company
taking reasonable measures available to it.

          The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the Indenture or any supplemental
indenture or the rights and obligations of the Company and the rights of the
Holders of the Securities of each series to be affected under the Indenture at
any time by the Company and the Trustee with the consent of the Holders of a
majority in aggregate principal amount of the Securities at the time Outstanding
of all series to be affected (voting as a class). The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount
of the Securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, to waive compliance by the Company
with certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the Holder of
this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the registration
of transfer hereof or in exchange herefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Security.

          No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and 

                                       13
<PAGE>
 
unconditional, to pay the principal of (and premium, if any) and interest, if
any, on this Security at the times, place and rate, and in the coin or currency,
herein prescribed.

          This Security shall be exchangeable, in whole but not in part, for
Securities registered in the names of Persons other than the Book-Entry
Depositary with respect to such series or its nominee only as provided in this
paragraph. This Security shall be so exchangeable if (a) DTC notifies the
Company and the Book-Entry Depositary that it is unwilling or unable to continue
to hold the Book-Entry Interest or at any time it ceases to be a "clearing
agency" registered as such under the Exchange Act and in either case, a
successor is not appointed by the Company within 120 days, (b) the Book-Entry
Depositary for the Securities of this series notifies the Company that it is
unwilling or unable to continue as Book-Entry Depositary with respect to this
Security and no successor is appointed within 120 days, (c) the Company executes
and delivers to the Trustee an Officers' Certificate providing that this
Security shall be so exchangeable, or (d) there shall have occurred and be
continuing an Event of Default with respect to the Securities of this series and
the Holder, in such circumstance, shall have requested in writing that this
Security be exchanged for one or more definitive Registered Securities of this
series. Securities so issued in exchange for this Security shall be of the same
series, having the same interest rate, if any, and maturity and having the same
terms as this Security, in authorized denominations and in the aggregate having
the same principal amount as this Security and registered in such names as the
Book-Entry Depositary for this Security shall direct.

          The bearer of this Security shall be treated as the owner of it for
all purposes, subject to the terms of the Indenture. As provided in the
Indenture and subject to certain limitations therein set forth, Securities of
this series are exchangeable for a like aggregate principal amount of Securities
of this series and of like tenor of a different authorized denomination, as
requested by the Holder surrendering the same.

          No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

          When a successor assumes all the obligations of its predecessor under
the Securities of this series and the Indenture in accordance with the terms of
the Indenture, the predecessor will be released from those obligations.

          The Trustee under the Indenture, in its individual or any other
capacity, may become the owner or pledgee of Securities of this series and may
otherwise deal with the Company, its Subsidiaries or their respective Affiliates
as if it were not the Trustee.

          No stockholder, director, officer, employee, incorporator or Affiliate
of the Company shall have any liability for any obligation of the Company under
the Securities of this series or the Indenture or for any claim based on, in
respect of or by reason of, such obligations of their creation. Each Holder of
the Securities of this series by accepting 

                                       14
<PAGE>
 
Securities this series waives and releases all such liability. The waiver and
release are part of the consideration for the issuance of the Securities of this
series.

          This Security shall not be valid until the Trustee or authenticating
agent signs the certificate of authentication on this Security.

          Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company will cause CUSIP numbers to be
printed on the Securities of this series as a convenience to the Holders of the
Securities of this series. No representation is made as to the accuracy of such
numbers as printed on the Securities of this series and reliance may be placed
only on the other identification numbers printed hereon.

          This Security shall be governed by and construed in accordance with
the laws of the State of New York.

          All terms used in this Security which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

having power to tax ("United Kingdom Taxes"), unless such withholding or
deduction is required by law.  In the event of any such withholding or
deduction, the Company shall pay to the Holder such additional amounts
("Additional Amounts") as will result in the payment to such Holder of the
amount that would otherwise have been receivable by such Holder in the absence
of such withholding or deduction, except that no such Additional Amounts shall
be payable:

          (a) to, or to a Person on behalf of, a Holder who is liable for such
     United Kingdom Taxes in respect of this Security by reason of such Holder
     having some connection with the United Kingdom (including a citizen or
     resident or national of, or carrying on a business or maintaining a
     permanent establishment in, or being physically present in , the United
     Kingdom) other than the mere holding of this Security or the receipt of
     principal and interest (including payments of discount and premium, if any)
     in respect thereof;

          (b) to, or to a Person on behalf of, a Holder who presents this
     Security (where presentation is required) for payment more than 30 days
     after the Relevant Date except to the extent that the Holder would have
     been entitled to such Additional Amounts on presenting this Security for
     payments on the last day of such period of 30 days;

          (c) to, or to a Person on behalf of, a Holder who presents a Security
     (where presentation is required) in the United Kingdom;

          (d) to, or to a Person on behalf of, a Holder who would not be liable
     or subject to the withholding or deduction by making a declaration of non-
     residence or similar claim for exemption to the relevant tax authority; or

          (e) to, or to a Person on behalf of, a Holder of a definitive
     Registered Security issued pursuant to the request of owners of interests
     representing a majority in outstanding principal amount in the Book-Entry
     Interest following and during the continuance of an Event of Default if
     such Holder (or any predecessor Holder) was one of such owners requesting
     that definitive Registered Securities be so issued.

     Such Additional Amounts will also not be payable where, had the beneficial
owner of the Security (or any interest therein) been the Holder of the Security,
he would not have been entitled to payment of Additional Amounts by reason of
any one or more of clauses (a) through (e) above.  If the Company shall
determine that Additional Amounts will not be payable

                                       17
<PAGE>
 
because of the immediately preceding sentence, the Company will inform such
Holder promptly after making such determination setting forth the reason(s)
therefor.

          "Relevant Date" means whichever is the later of (i) the date on which
such payment first becomes due and (ii) if the full amount payable has not been
received in The City of New York by the Trustee or the Holder on or prior to
such due date, the date on which, the full amount having been so received,
notice to that effect shall have been given to the Holder in accordance with
this Indenture.

          References to principal, interest, discount or premium in respect of
this Security shall be deemed also to refer to any Additional Amounts which may
be payable as set forth in the Indenture or in this Security.

          The Company shall furnish to the Trustee the official receipts (or a
certified copy of the official receipts) evidencing payment of United Kingdom
Taxes.  Copies of such receipts shall be made available to the Holder of this
Security upon request.

          So long as the Securities of this series are listed on the Luxembourg
Stock Exchange and the rules of the Luxembourg Stock Exchange so require,
notices to Holders of Securities of this series will be published in a leading
newspaper having general circulation in Luxembourg (which is expected to be the
Luxemburger Wort).

          REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS SECURITY
SET FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES
HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE.

          Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

          IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed by an officer or director of the Company duly authorized.

                          ___% Senior Notes Due 2006


          This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or more
series under an Indenture, dated as of ________ __, 1996 (herein called the
"Original Indenture"), among the Company, Bankers Trust Company, as trustee
(herein called the "Trustee", which term includes any successor trustee under
the Indenture), and Bankers Trust Luxembourg S.A., as paying and transfer agent
(the "Paying and Transfer Agent"), as supplemented by the First Supplemental
Indenture, dated as of _______ __, 1996 (together with the Original Indenture,
the "Indenture") among the Company, the Trustee and the Paying and Transfer
Agent to which Indenture and all indentures supplemental thereto reference is
hereby made for a statement of the respective rights, limitations of rights,
duties and immunities thereunder of the Company, the Trustee the Paying and
Transfer Agent and the Holders of the Securities and of the terms upon which the
Securities are, and are to be, authenticated and delivered.  This Security is
one of the series designated on the face hereof, limited in aggregate principal
amount to $________________.

          The Securities of this series will be redeemable in whole or in part,
at the option of the Company at any time, at a redemption price equal to the
greater of (i) 100% of the principal amount of the Securities of this series
being redeemed or (ii) the sum of the present values of the remaining scheduled
payments of principal of and interest on the Securities of this series being
redeemed discounted to the date of redemption on a semiannual basis (assuming a
360-day year consisting of twelve 30-day months) at a discount rate equal to the
Treasury Yield plus ___ basis points, plus, for (i) or (ii) above, whichever is
applicable, accrued interest on the Securities of this series to the date of
redemption.

          "Treasury Yield" means, with respect to any redemption date, the rate
per annum equal to the semiannual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as
a percentage of its principal amount) equal to the Comparable Treasury Price for
such redemption date.

          "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term of such Securities of this series to be redeemed that would
be utilized, at the time of selection and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable
maturity to the remaining term of the Securities of this series.

                                       19
<PAGE>
 
          "Comparable Treasury Price" means, with respect to any redemption
date, (i) the average of the bid and asked prices for the Comparable Treasury
Issue (expressed in each case as a percentage of its principal amount) on the
third Business Day in New York City preceding such redemption date, as set forth
in the daily statistical release (or any successor release) published by the
Federal Reserve Bank of New York and designated "Composite 3:30 p.m. Quotations
for US Government Securities" or (ii) if such release (or any successor release)
is not published or does not contain such prices on such business day, the
Reference Treasury Dealer Quotation for such redemption date.

          "Independent Investment Banker" means an independent investment
banking institution of national standing appointed by the Company and reasonably
acceptable to the Trustee.

          "Reference Treasury Dealer Quotation" means, with respect to the
Reference Treasury Dealer and any redemption date, the average, as determined by
the Trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount and quoted in
writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the
third business day preceding such redemption date).

          "Reference Treasury Dealer" means a primary US Government securities
dealer in New York City appointed by the Company and reasonably acceptable to
the Trustee.

          Notice of redemption shall be given as provided in the Indenture not
less than 15 days nor more than 30 days prior to the date fixed for redemption.

          If fewer than all the Securities of this series are to be redeemed,
selection of Securities for redemption will be made by the Trustee in any manner
the Trustee deems fair and appropriate and that complies with applicable legal
and securities exchange requirements.

          Unless the Company defaults in payment of the redemption price, from
and after the redemption date, the Securities of this series or portions thereof
called for redemption will cease to bear interest, and the Holders thereof will
have no right in respect to such Securities of this series except the right to
receive the redemption price thereof.

          In the event of redemption of this security in part only, a new
Security or Securities of this series and of like tenor for the unredeemed
portion hereof will be issued in the name of the Holder hereof upon the
cancellation hereof.

          The Indenture contains provisions for defeasance of (a) the entire
indebtedness of this Security and (b) certain restrictive covenants upon
compliance by the Company with certain conditions set forth therein.

          If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the

                                       20
<PAGE>
 
manner and with the effect provided in the Indenture. At any time after such
declaration of acceleration with respect to Securities of any series has been
made, but before a judgment or decree for payment of money has been obtained by
the Trustee as provided in the Indenture, if all Events of Default with respect
to Securities of this series have been cured or waived (other than the non-
payment of principal of the Securities which has become due solely by reason of
such declaration of acceleration) then such declaration of acceleration and its
consequences shall be automatically annulled and rescinded.

          The Securities of this series are subject to redemption upon not less
than 15 nor more than 30 days' notice to the Holders of Securities by first-
class mail, at a price equal to the outstanding principal amount thereof,
together with Additional Amounts, if any, and accrued interest, if any, to the
Redemption Date if (a) the Company satisfies the Trustee prior to the giving of
such notice that it has or will become obliged to pay Additional Amounts as a
result of either (x) any change in, or amendment to, the laws or regulations of
the United Kingdom or any political subdivision or any authority or agency
thereof or therein having power to tax or levy duties, or any change in the
application or interpretation of such laws or regulations, which change or
amendment becomes effective on or after the [date of the underwriting
agreement], or (y) the issuance of definitive Registered Securities as a result
of: (i) DTC having notified the Company and the Book-Entry Depositary that it
was unwilling or unable to continue to hold the Book-Entry Interest or at any
time ceasing to be a "clearing agency" registered as such under the Securities
Exchange Act of 1934 and, in either case, a successor is not being appointed by
the Company within 120 days; (ii) the Book-Entry Depositary for the Securities
of this series having notified the Company that it was unwilling or unable to
continue as Book-Entry Depositary with respect to a Global Security of this
series and no successor Book-Entry Depositary having been appointed by the
Company within 120 days, or; (iii) an Event of Default with respect to the
Securities of this series having occurred and being continuing and a Holder, in
such circumstance, having requested in writing that a Global Bearer Security of
this series be exchanged for one or more definitive Registered Securities and
(b) such obligation cannot be avoided by the Company taking reasonable measures
available to it, subject, as provided in the Indenture, to the delivery by the
Company of an Officers Certificate that such obligation referred to in (a)
cannot be avoided by the Company taking reasonable measures available to it.

          The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the Indenture or any supplemental
indenture or the rights and obligations of the Company and the rights of the
Holders of the Securities of each series to be affected under the Indenture at
any time by the Company and the Trustee with the consent of the Holders of a
majority in aggregate principal amount of the Securities at the time Outstanding
of all series to be  affected (voting as a class).  The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount
of the securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, to waive compliance by the Company
with certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences.  Any such consent or waiver by the Holder of
this Security shall be conclusive and binding upon such Holder and upon all
future

                                       21
<PAGE>
 
Holders of this Security and of any Security issued upon the registration of
transfer hereof or in exchange herefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Security.

          No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of (and premium, if any) and
interest, if any, on this Security at the times, place and rate, and in the coin
or currency, herein prescribed.

          As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Company in any place where the principal of (and
premium, if any) and interest, if any, on this Security are payable, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed by the
Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Securities of this series and of like tenor, of authorized
denominations and for the same aggregate principal amount, will be issued to the
designated transferee or transferees.

          The Securities of this series are issuable only in registered form
without coupons in denominations of $1,000 and any integral multiple thereof.
As provided in the Indenture and subject to certain limitations therein set
forth, Securities of this series are exchangeable for a like aggregate principal
amount of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.

          No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

          Prior to due presentment of this Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Security is registered as the owner
hereof for all purposes, whether or not this Security be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

          When a successor assumes all the obligations of its predecessor under
the Securities of this series and the Indenture in accordance with the terms of
the Indenture, the predecessor will be released from those obligations.

          The Trustee under the Indenture, in its individual or any other
capacity, may become the owner or pledgee of Securities of this series and may
otherwise deal with the Company, its Subsidiaries or their respective Affiliates
as if it were not the Trustee.

                                       22
<PAGE>
 
          No stockholder, director, officer, employee, incorporator or Affiliate
of the Company shall have any liability for any obligation of the Company under
the Securities of this series or the Indenture or for any claim based on, in
respect of or by reason of, such obligations or their creation.  Each Holder of
the Securities of this series by accepting a Security of this series waives and
releases all such liability.  The waiver and release are part of the
consideration for the issuance of the Securities of this series.

          This Security shall not be valid until the Trustee or authenticating
agent signs the certificate of authentication on this Security.

          Customary abbreviations may be used in the name of a Holder of a
Securities of this series or an assignee, such as:  TEN COM (= tenants in
common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with
right of survivorship and not as tenants in common), CUST (= Custodian), and
U/G/M/A (= Uniform Gifts to Minors Act).

          Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company will cause CUSIP numbers to be
printed on the Securities of this series as a convenience to the Holders of the
Securities of this series.  No representation is made as to the accuracy of such
numbers as printed on the Securities of this series and reliance may be placed
only on the other identification numbers printed hereon.

          This Security shall be governed by and construed in accordance with
the laws of the State of New York.

          All terms used in this Security which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

or to act in respect of any such matter.  Subject to the provisions of this
Agreement, only the Depositary who is registered on the Book-Entry Register at

          (b) The Depositary may direct the time, method and place of conducting
any proceeding for any remedy available to the Book-Entry Depositary or of
exercising any trust or power conferred on the Book-Entry Depositary. However,
the Book-Entry Depositary may refuse to follow any direction that conflicts with
law or this Agreement or the Indenture or, subject to Section 3.01 hereof, that
the Book-Entry Depositary determines would involve it in Personal liability.

of such resignation. The Book-Entry Depositary may be removed at any time upon

behalf of the Company and specifying such removal and the date when it is
intended to become effective. If the instrument of acceptance by a successor
Book-Entry Depositary required by Section 3.09 hereof shall not have been
delivered to the Book-Entry Depositary within 30 days after the giving of such
notice of resignation or removal, the resigning Book-Entry Depositary may
petition any court of competent jurisdiction for the appointment of a successor
Book-Entry Depositary.

     (c)  If at any time:

                                       10
<PAGE>
 
     (i) the Book-Entry Depositary shall cease to be eligible under Section 3.07
     hereof, or shall cease to be eligible as Trustee under the Indenture, and

     its property shall be appointed or any public officer shall take charge or
     control of the Book-Entry Depositary or of its property or affairs for the
     purpose of rehabilitation, conservation or liquidation.

then, in any such case, (i) the Company, by Board Resolution, may remove the
Book-Entry Depositary and appoint a successor Book-Entry Depositary, and (ii) if
the Company shall fail to remove such Book-Entry Depositary and appoint a
successor Book-Entry Depositary, the Depositary may, on behalf of itself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Book-Entry Depositary or Book-Entry Depositaries and the
appointment of a successor Book-Entry Depositary, unless Definitive Registered
Notes have been issued in accordance with the Indenture.

     (d) If the Book-Entry Depositary shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Book-Entry
Depositary for any cause, the Company, by Board Resolution, shall promptly
appoint a successor Book-Entry Depositary (other than the Company) and shall
comply with the applicable requirements of Section 3.09 hereof. If no successor
Book-Entry Depositary with respect to the Global Note shall have been so
appointed by the Company and accepted appointment in the manner required by
Section 3.09, the Depositary may, on behalf of itself and all others similarly
situated, petition any court of competent jurisdiction for the appointment of a
successor Book-Entry Depositary unless Definitive Registered Notes have been
issued in accordance with the Indenture.

     (e) The Company shall give, or shall cause such successor Book-Entry
Depositary to give, notice of each resignation and each removal of a Book-Entry
Depositary and each appointment of a successor Book-Entry Depositary to the

     SECTION 3.09. Acceptance of Appointment by Successor. (a) In case of the
                   -------------------------------------- 
appointment hereunder of a successor Book-Entry Depositary, every such successor
Book-Entry Depositary so appointed shall execute, acknowledge and deliver to the
Company and to the retiring Book-Entry Depositary an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Book-Entry
Depositary shall become effective and such successor Book-Entry Depositary,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, agencies and duties of the retiring Book-Entry Depositary, with
like effect as if originally named as Book-Entry Depositary hereunder; but, on
the request of the Company or the successor Book-Entry Depositary, such retiring
Book-Entry Depositary shall, upon payment of all amounts due and payable to it
pursuant to Section 3.06 hereof, execute and deliver an instrument transferring
to such successor Book-Entry Depositary all the rights and powers of the
retiring Book-Entry Depositary and shall duly

                                       11
<PAGE>
 
assign, transfer and deliver to such successor Book-Entry Depositary all
property and money held by such retiring Book-Entry Depositary hereunder. Any
retiring Book-Entry Depositary shall, nonetheless, retain a prior claim upon all
property or funds held or collected by such Book-Entry Depositary to secure any
amounts then due it pursuant to Section 3.06 hereof.

     (b) Upon request of any such successor Book-Entry Depositary, the Company
shall execute any and all instruments for more fully and certainly vesting in
and confirming to such successor Book-Entry Depositary all such rights, powers
and agencies referred to in paragraph (a) of this Section 3.09.

     (c) No successor Book-Entry Depositary shall accept its appointment unless
at the time of such acceptance such successor Book-Entry Depositary shall be
eligible under this Article.

     (d) Upon acceptance of appointment by any successor Book-Entry Depositary
as provided in this Section 3.09, the Company shall give notice thereof to the
Depositary in accordance with Section 4.02 hereof. If the acceptance of
appointment is substantially contemporaneous with the resignation of the Book-
Entry Depositary, then the notice called for by the preceding sentence may be
combined with the notice called for by Section 3.08(b) hereof. If the Company
fails to give such notice within 10 days after acceptance of appointment by the
successor Book-Entry Depositary, the successor Book-Entry Depositary shall cause
such notice to be given at the expense of the Company.

     SECTION 3.10. Merger, Conversion, Consolidation or Succession to Business.
                   -----------------------------------------------------------
Any corporation into which the Book-Entry Depositary may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Book-Entry Depositary shall be
a party, or any corporation succeeding to all or substantially all the corporate
trust business of the Book-Entry Depositary, shall be the successor of the Book-
Entry Depositary hereunder, without the execution of filing of any paper or any
further act on the part of any of the parties hereto.

Southern Investments UK plc

    RE:  Registration Statement on Form S-1

Gentlemen:

    We have acted as counsel to Southern Investments UK plc (the "Company") in
connection with the preparation of a Registration Statement on Form S-1, 
including a preliminary prospectus, filed with the Securities and Exchange 
Commission (the "Commission") on July 29, 1996 (File No. 333-09033) as amended
by Amendment No. 1 filed with the Commission on August 28, 1996, and by 
Amendment No. 2 filed with the Commission on September 24, 1996, (as so 
amended, the "Registration Statement"), for the registration under the 
Securities Act of 1933, as amended (the "Act"), of Senior Notes (the "Senior 
Notes") to be issued by the Company pursuant to an indenture between the Company
and the trustee named therein (the "Indenture") and pursuant to the supplemental
indenture between the Company and the trustee named therein (the "First 
Supplemental Indenture"), in each case in the respective forms filed as exhibits
to the Registration Statement.

    In this capacity, we have examined originals, or copies certified or 
otherwise identified to our satisfaction, of such documents as we have deemed 
necessary as a basis for the opinion hereinafter expressed. In our examinations,
we have assumed the genuineness of all signatures, the legal capacity of natural
persons, the authenticity of all documents presented to us as originals and the 
conformity with the originals of all documents submitted to us as copies.

    Based upon such examination and the assumptions set forth herein, subject to
the limitations set forth herein and having considered such questions of law as 
we have deemed necessary as a basis for the opinion expressed below, we are of 
the opinion that, upon compliance with the pertinent provisions of the Act and 
the Trust Indenture Act of 1939, as amended, upon the adoption of appropriate 
resolutions of the Board of Directors of the Company or a duly authorized 
committee thereof, when the Indenture and the Senior Notes have been duly 
executed by the parties thereto substantially in the form filed as exhibit to 
the Registration Statement and the Senior Notes have been duly authenticated by 
the Trustee in the manner contemplated in the Indenture and duly delivered to 
and paid for by the Underwriters (as defined in the attached opinion of Shearman
& Sterling) in accordance with the terms of the Underwriting Agreement (as 
defined in the attached opinion of Shearman & Sterling), the Senior Notes will 
constitute valid and legally binding obligations of the Company, enforceable 
against the Company in accordance with their terms, except as enforcement 
thereof may be limited by applicable bankruptcy, insolvency (including, without 
limitation, all laws relating to fraudulent transfers), reorganization, 
moratorium or similar laws affecting enforcement of creditors' rights generally 
and except as enforcement thereof is subject to possible judicial acting giving 
effect to foreign governmental

actions or foreign laws affecting creditors' rights and to general principles of
equity, including, without limitation, concepts of materiality, reasonableness, 
good faith and fair dealing (regardless of whether enforcement is considered in 
a proceeding in equity or at law).

    In rendering the opinion expressed above, we have assumed the due existence 
of each party to each document referred to therein, that the execution and 
delivery of each such document will be effected in accordance with all laws, 
regulations, procedures and contractual restrictions applicable to the party 
taking such action and that such action will not violate any such law, 
regulation, contractual restriction or procedure.

     We are attorneys admitted to practice in the State of Georgia and we do 
not express any opinion herein concerning any law other than the law of the 
State of Georgia, the State of New York and the federal law of the United 
States. To the extent that our opinion expressed herein relates to the law of 
the State of New York, we have relied exclusively on the opinion of Shearman & 
Sterling attached hereto as Exhibit A.

     We hereby consent to the filing of this opinion as an exhibit to the 
Registration Statement and to the statements with respect to our firm under the 
caption "Legal Matters" in the Registration Statement.

                                    Very truly yours,

          England

Dear Sirs:

          We have acted as legal advisers as to English law to Southern
Investments UK plc, a public limited company incorporated under the laws of
England and Wales (the "Company"), in connection with the preparation of the
registration statement on Form S-1 (Registration No. 333-09033), filed by the
Company under the U.S. Securities Act of 1933, as amended, (the "Securities
Act") with the U.S. Securities and Exchange Commission (the "Commission") on
29/th/ July, 1996, and the amendments thereto filed by the Company with the
Commission on 28/th/ August, 1996 , and 26/th/ September, 1996, respectively
(the registration statement as amended being hereinafter referred to as the
"Registration Statement"), all in connection with the issue by the Company of
U.S. $235,000,000 aggregate principal amount of the Company's Senior Notes due
2006 (the "Senior Notes") to be issued under and governed by an Indenture (the
"Indenture") between the Company and the Bankers Trust Company, as trustee (the
"Trustee"). The Senior Notes will be represented by a global Note in bearer form
(the "Global Note") which will be deposited on issue with Bankers Trust Company,
as depositary (the "Book-entry Depositary"), under a deposit agreement (the
"Deposit Agreement") between (inter alia) the Company and the Book-Entry
Depositary. The Book-Entry Depositary will issue one or more certificateless
depositary interests (the "CDIs") with respect to the Senior Notes to The
Depository Trust Company ("DTC"), which will then record beneficial interests in
the Senior Notes. Beneficial interests in the Senior Notes that will be shown on
records maintained in book-entry form by DTC are referred to herein as the Book-
Entry Interests. Under certain circumstances as provided for in the Indenture,
holders of Book-Entry Interests will be entitled to receive definitive Senior
Notes in registered form (the "Definitive Registered Notes") in exchange for
their holdings of Book-Entry Interests. References herein to the Senior Notes
shall, unless the context otherwise requires, include the Global Note and the
Definitive Registered Notes.

          We have examined copies of:

(a)       the Memorandum and Articles of Association of the Company;

(b)       a resolution of the Board of Directors of the Company passed on 26/th/
          July, 1996;

(c)       the Registration Statement;

(d)       a draft dated 20/th/ August, 1996 of the underwriting agreement
          relating to the Senior Notes (the "Underwriting Agreement") to be
          entered into by the Company and others;

(e)       a draft dated 24/th/ September, 1996 of the Indenture;

(f)       a draft dated 24/th/ September, 1996 of the First Supplemental
          Indenture (the "First Supplemental Indenture") to be made between the
          Company and the Trustee including the form of the Global Note;

(g)       a draft dated 23/rd/ September, 1996 of the Deposit Agreement; and

(h)       a certificate of the Secretary to the effect that the issue of the
          Senior Notes will not cause any limit on borrowings to which the
          Company is subject to be exceeded.

          Our opinion is confined solely to the laws of England.

          The Underwriting Agreement, the Indenture, the First Supplemental
Indenture and the Deposit Agreement will be expressed to be governed by the laws
of the State of New York. We have made no investigation of such laws and do not
express or imply any opinion on such laws.

          We have assumed that:

(i)       each of the Underwriting Agreement, the Indenture, the First
          Supplemental Indenture, the Deposit Agreement and the Global Note will
          be executed and delivered in the form of the relevant draft referred
          to above;

(ii)      insofar as any obligation falls to be performed in any jurisdiction
          outside England, its performance will not be illegal or ineffective by
          virtue of the laws of that jurisdiction;

(iii)     all signatures on the executed documents which, or copies of which, we
          have examined are genuine;

(iv)      each of the parties to the Underwriting Agreement, the Indenture, the
          First Supplemental Indenture and the Deposit Agreement, other than the
          Company, is able lawfully to enter into and to perform such agreement;

(v)       the execution and delivery of the Underwriting Agreement, the
          Indenture, the First Supplemental Indenture and the Deposit Agreement
          have been duly by each of the parties thereto, other than the Company,
          and that such documents will be duly executed and delivered by such
          parties (other than the Company);

(vi)      each of the parties to the Underwriting Agreement, the Indenture, the
          First Supplemental Indenture and the Deposit Agreement who is carrying
          on, or purporting to carry on, investment business in the United
          Kingdom is an authorised person or an exempted person under the
          Financial Services Act 1986 (the "FSA");

(vii)     the copy of the Memorandum and Articles of Association of the Company
          referred to above is true and up-to-date, and the resolution referred
          to above was duly passed in accordance with the Articles of
          Association of the Company;

(viii)    the absence of any other arrangements between any of the parties to
          the Underwriting Agreement, the Indenture, the First Supplemental
          Indenture, the Deposit Agreement or the Senior Notes which modify or
          supersede any of their terms;

(ix)      the certificate referred to in paragraph (h) above is true and
          accurate;

(x)       all documents presented to us as originals are true and accurate and
          all documents submitted to us as copies conform with the originals;
          and

(xi)      the terms of and documents relating to, the issue of the Senior Notes
          will be duly approved by the Finance Committee of the Board of
          Directors of the Company appointed pursuant to the resolution referred
          to in paragraph (b) above.

          On the basis of the foregoing, and having regard to such legal
considerations as we deem relevant and subject as set out below, we are of the
opinion that:

1.        The Company is duly incorporated and validly existing as a public
          company with limited liability under the laws of England, and has the
          corporate power and authority under such laws to own, lease and
          operate its properties and conduct its business as described in the
          Registration Statement. We have on 18/th/ September, 1996 made a
          search at the Companies Registry which revealed no order or resolution
          for the winding up of the Company and no notice of appointment of a
          receiver or administrator. However, the search would not reveal
          whether or not a winding up petition has been presented. Furthermore
          it is possible that notice of a winding up order made or resolution
          passed or a receiver or administrator appointed may not have been
          filed at the Companies Registry immediately. We have also on 19/th/
          September, 1996 made an inquiry of the Companies Court which has
          informed us that it has on its central index no record of the
          presentation of any winding up petition in respect of the Issuer. We
          are assuming that there has been no change in this position since the
          date on which the searches were made.

2.        The Underwriting Agreement, the Indenture, the First Supplemental
          Indenture and the Deposit Agreement have been duly authorised by the
          Company. There is no reason, so far as English law is concerned, why
          the Underwriting Agreement, the Indenture, the First Supplemental
          Indenture and the Deposit Agreement should not, upon execution and
          delivery thereof, constitute legal, valid, binding and enforceable
          obligations of the Company. As used in this opinion, the term
          "enforceable" means that each obligation or document is of a type and
          form enforced by the English courts. It is not certain, however, that
          each obligation or document will be enforced in accordance with its
          terms in every circumstance, enforcement being subject to, inter alia,
          the nature of the remedies available in the English courts, the
          acceptance by such courts of jurisdiction, the power of such courts to
          stay proceedings, the provisions of the Limitation Act 1980 and other
          principles of law and equity of general application and all
          limitations resulting from the laws of bankruptcy, insolvency,
          liquidation or other laws affecting generally the enforcement of
          creditors' rights.

3.        The issue of the Senior Notes has been duly authorised by the Company.
          There is no reason, so far as English law is concerned, why the Global
          Note (when executed, authenticated and delivered in the manner
          described in the Indenture) should not constitute a legal, valid
          binding and enforceable obligation of the Company or why the
          Definitive Registered Notes (when executed, authenticated and
          delivered in the manner described in the Indenture) should not
          constitute valid evidence of enforceable obligations of the Company.

4.        The statements in the Registration Statement under the heading
          "Certain Income Tax Considerations - UK Income Tax Considerations"
          insofar as such statements constitute summaries of certain UK tax laws
          and UK Inland Revenue practice, are correct in all material respects.

          This opinion is subject to the following:

(a)       There could be circumstances in which an English court would not treat
          as conclusive those certificates and determinations which the
          Underwriting Agreement, the Indenture, the First Supplements
          Indenture, the Deposit Agreement and the Senior Notes state are to be
          so treated.

(b)       Any provision in the Underwriting Agreement, the Indenture, the First
          Supplemental Indenture or the Deposit Agreement which involves an
          indemnity for the costs of litigation is subject to the discretion of
          the court to decide whether and to what extent a party to litigation
          should be awarded the costs incurred by it in connection with the
          litigation.

To:       Southern Investments UK plc               26/th/ September, 1996
Page : 4 


(c)       Any provision in any agreement which amounts to an undertaking to
          assume the liability on account of the absence of payment of stamp
          duty or an indemnity to pay stamp duty may be void.

(d)       Any person who is not a party to an agreement may not be able to
          enforce any provisions of that agreement which are expressed to be for
          the benefit of that person.

(e)       The Registration Statement has been issued by the Company who has
          accepted responsibility for the information contained therein. Save to
          the extent referred to in paragraph 4 above, we have not investigated
          or verified the truth or accuracy of the information contained in the
          Registration Statement, nor have we been responsible for ensuring that
          no material information has been omitted from it.

(f)       The effectiveness of terms exculpating a party from a liability or
          duty otherwise owed are limited by law.

          We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and the use of our name under the headings "Certain
Income Tax Considerations - UK Income Tax Considerations" and "Legal Matters" in
the Registration Statement.  In giving such consent we do not admit that we come
within the category of persons whose consent is required under Section 7 of the
Securities Act.

          This opinion, which shall be construed in accordance with English law,
is given to the Company in connection with the issue of the Senior Notes. You
agree, by your acceptance of this opinion, that any proceedings which may be
brought by you against us in relation to this opinion shall only be brought in
the courts of England. You are requested not to give copies of this opinion to
others without our prior written permission except as referred to above.

                              Yours faithfully,



                              ALLEN & OVERY

Dear Sirs:

     We are acting as counsel to Southern Investments UK plc (the "Company") in
connection with the preparation, authorization, execution and filing of the
Registration Statement (Reg. No. 333-09033) on Form S-1 (the "Registration
Statement") under the Securities Act of 1933, as amended, with respect to the
registration of Senior Notes of the Company (the "Senior Notes").

     We have examined originals or copies, certified or otherwise identified to
our satisfaction, of such corporate records, agreements, documents and other
instruments and such certificates or comparable documents of public officials
and representatives of the Company, and have made such other and further
investigations, as we have deemed relevant and necessary as a basis for the
opinions hereinafter set forth.

     In such examination, we have assumed the genuineness of all signatures, the
legal capacity of natural persons, the authenticity of all documents submitted
to us as originals, the conformity to original documents of all documents
submitted to us as certified or photostatic copies, and the authenticity of the
originals of such latter documents.

     Based on the foregoing, and subject to the qualifications and limitations
stated herein, we are of the opinion that the statements made in the
Registration Statement under the heading "Certain Income Tax Considerations--
U.S. Federal Income Tax Considerations," insofar as they purport to constitute
summaries of matters of certain U.S. federal income tax laws and regulations,
are confirmed in all material respects.

          England

Dear Sirs:

          We have acted as legal advisers as to English law to Southern
Investments UK plc, a public limited company incorporated under the laws of
England and Wales (the "Company"), in connection with the preparation of the
registration statement on Form S-1 (Registration No. 333-09033), filed by the
Company under the U.S. Securities Act of 1933, as amended, (the "Securities
Act") with the U.S. Securities and Exchange Commission (the "Commission") on
29th July, 1996, and the amendments thereto filed by the Company with the
Commission on 28th August, 1996 , and 26th September, 1996, respectively (the
registration statement as amended being hereinafter referred to as the
"Registration Statement"), all in connection with the issue by the Company of
U.S. $235,000,000 aggregate principal amount of the Company's Senior Notes due
2006 (the "Senior Notes") to be issued under and governed by an Indenture (the
"Indenture") between the Company and the Bankers Trust Company, as trustee (the
"Trustee"). The Senior Notes will be represented by a global Note in bearer form
(the "Global Note") which will be deposited on issue with Bankers Trust Company,
as depositary (the "Book-entry Depositary"), under a deposit agreement (the
"Deposit Agreement") between (inter alia) the Company and the Book-Entry
Depositary. The Book-Entry Depositary will issue one or more certificateless
depositary interests (the "CDIs") with respect to the Senior Notes to The
Depository Trust Company ("DTC"), which will then record beneficial interests in
the Senior Notes. Beneficial interests in the Senior Notes that will be shown on
records maintained in book-entry form by DTC are referred to herein as the Book-
Entry Interests. Under certain circumstances as provided for in the Indenture,
holders of Book-Entry Interests will be entitled to receive definitive Senior
Notes in registered form (the "Definitive Registered Notes") in exchange for
their holdings of Book-Entry Interests. References herein to the Senior Notes
shall, unless the context otherwise requires, include the Global Note and the
Definitive Registered Notes.

          We have examined copies of:

(a)       the Memorandum and Articles of Association of the Company;

(b)       a resolution of the Board of Directors of the Company passed on 26th
          July, 1996;

(c)       the Registration Statement;

(d)       a draft dated 20th August, 1996 of the underwriting agreement relating
          to the Senior Notes (the "Underwriting Agreement") to be entered into
          by the Company and others;

(e)       a draft dated 24th September, 1996 of the Indenture;

(f)       a draft dated 24th September, 1996 of the First Supplemental Indenture
          (the "First Supplemental Indenture") to be made between the Company
          and the Trustee including the form of the Global Note;

(g)       a draft dated 23rd September, 1996 of the Deposit Agreement; and

(h)       a certificate of the Secretary to the effect that the issue of the
          Senior Notes will not cause any limit on borrowings to which the
          Company is subject to be exceeded.

          Our opinion is confined solely to the laws of England.

          The Underwriting Agreement, the Indenture, the First Supplemental
Indenture and the Deposit Agreement will be expressed to be governed by the laws
of the State of New York. We have made no investigation of such laws and do not
express or imply any opinion on such laws.

          We have assumed that:

(i)       each of the Underwriting Agreement, the Indenture, the First
          Supplemental Indenture, the Deposit Agreement and the Global Note will
          be executed and delivered in the form of the relevant draft referred
          to above;

(ii)      insofar as any obligation falls to be performed in any jurisdiction
          outside England, its performance will not be illegal or ineffective by
          virtue of the laws of that jurisdiction;

(iii)     all signatures on the executed documents which, or copies of which, we
          have examined are genuine;

(iv)      each of the parties to the Underwriting Agreement, the Indenture, the
          First Supplemental Indenture and the Deposit Agreement, other than the
          Company, is able lawfully to enter into and to perform such agreement;

(v)       the execution and delivery of the Underwriting Agreement, the
          Indenture, the First Supplemental Indenture and the Deposit Agreement
          have been duly by each of the parties thereto, other than the Company,
          and that such documents will be duly executed and delivered by such
          parties (other than the Company);

(vi)      each of the parties to the Underwriting Agreement, the Indenture, the
          First Supplemental Indenture and the Deposit Agreement who is carrying
          on, or purporting to carry on, investment business in the United
          Kingdom is an authorised person or an exempted person under the
          Financial Services Act 1986 (the "FSA");

(vii)     the copy of the Memorandum and Articles of Association of the Company
          referred to above is true and up-to-date, and the resolution referred
          to above was duly passed in accordance with the Articles of
          Association of the Company;

(viii)    the absence of any other arrangements between any of the parties to
          the Underwriting Agreement, the Indenture, the First Supplemental
          Indenture, the Deposit Agreement or the Senior Notes which modify or
          supersede any of their terms;

(ix)      the certificate referred to in paragraph (h) above is true and
          accurate;

(x)       all documents presented to us as originals are true and accurate and
          all documents submitted to us as copies conform with the originals;
          and

(xi)      the terms of and documents relating to, the issue of the Senior Notes
          will be duly approved by the Finance Committee of the Board of
          Directors of the Company appointed pursuant to the resolution referred
          to in paragraph (b) above.

          On the basis of the foregoing, and having regard to such legal
considerations as we deem relevant and subject as set out below, we are of the
opinion that:

1.        The Company is duly incorporated and validly existing as a public
          company with limited liability under the laws of England, and has the
          corporate power and authority under such laws to own, lease and
          operate its properties and conduct its business as described in the
          Registration Statement. We have on 18th September, 1996 made a search
          at the Companies Registry which revealed no order or resolution for
          the winding up of the Company and no notice of appointment of a
          receiver or administrator. However, the search would not reveal
          whether or not a winding up petition has been presented. Furthermore
          it is possible that notice of a winding up order made or resolution
          passed or a receiver or administrator appointed may not have been
          filed at the Companies Registry immediately. We have also on 19th
          September, 1996 made an inquiry of the Companies Court which has
          informed us that it has on its central index no record of the
          presentation of any winding up petition in respect of the Issuer. We
          are assuming that there has been no change in this position since the
          date on which the searches were made.

2.        The Underwriting Agreement, the Indenture, the First Supplemental
          Indenture and the Deposit Agreement have been duly authorised by the
          Company. There is no reason, so far as English law is concerned, why
          the Underwriting Agreement, the Indenture, the First Supplemental
          Indenture and the Deposit Agreement should not, upon execution and
          delivery thereof, constitute legal, valid, binding and enforceable
          obligations of the Company. As used in this opinion, the term
          "enforceable" means that each obligation or document is of a type and
          form enforced by the English courts. It is not certain, however, that
          each obligation or document will be enforced in accordance with its
          terms in every circumstance, enforcement being subject to, inter alia,
          the nature of the remedies available in the English courts, the
          acceptance by such courts of jurisdiction, the power of such courts to
          stay proceedings, the provisions of the Limitation Act 1980 and other
          principles of law and equity of general application and all
          limitations resulting from the laws of bankruptcy, insolvency,
          liquidation or other laws affecting generally the enforcement of
          creditors' rights.

3.        The issue of the Senior Notes has been duly authorised by the Company.
          There is no reason, so far as English law is concerned, why the Global
          Note (when executed, authenticated and delivered in the manner
          described in the Indenture) should not constitute a legal, valid
          binding and enforceable obligation of the Company or why the
          Definitive Registered Notes (when executed, authenticated and
          delivered in the manner described in the Indenture) should not
          constitute valid evidence of enforceable obligations of the Company.

4.        The statements in the Registration Statement under the heading
          "Certain Income Tax Considerations - UK Income Tax Considerations"
          insofar as such statements constitute summaries of certain UK tax laws
          and UK Inland Revenue practice, are correct in all material respects.

          This opinion is subject to the following:

(a)       There could be circumstances in which an English court would not treat
          as conclusive those certificates and determinations which the
          Underwriting Agreement, the Indenture, the First Supplements
          Indenture, the Deposit Agreement and the Senior Notes state are to be
          so treated.

(b)       Any provision in the Underwriting Agreement, the Indenture, the First
          Supplemental Indenture or the Deposit Agreement which involves an
          indemnity for the costs of litigation is subject to the discretion of
