(1) Yorkshire Finance and Yorkshire Group have agreed to indemnify the several
    Underwriters against certain liabilities, including liabilities under the
    Securities Act of 1933, as amended. See "Underwriting".
(2) In view of the fact that the proceeds from the sale of the Trust Securities
    will be used to purchase the Junior Subordinated Debentures from Yorkshire
    Finance, the Underwriting Agreement provides that Yorkshire Finance will
    pay to the Underwriters, as compensation ("Underwriters' Compensation") for
    arranging the investment therein of such proceeds, $    per Trust Security
    (or $    in the aggregate); provided that such compensation will be $
    per Trust Security for sales of 10,000 or more Trust Securities to a single
    purchaser. Therefore, to the extent of such sales, the actual amount of
    Underwriters' Compensation will be less than the aggregate amount specified
    in the preceding sentence. See "Underwriting".
(3) Expenses of the offering, which are payable pursuant to the Agreement as to
    Expenses and Liabilities, are estimated to be $    .

  The Trust Securities offered hereby are offered severally by the
Underwriters, as specified herein, subject to receipt and acceptance by them
and subject to their right to reject any order in whole or in part. It is
expected that delivery of the Trust Securities will be only in book-entry form
through the facilities of The Depository Trust Company ("DTC"), on or about
   , 1998, against payment therefor in immediately available funds.

  CERTAIN PERSONS PARTICIPATING IN THIS OFFERING MAY ENGAGE IN TRANSACTIONS
THAT STABILIZE, MAINTAIN OR OTHERWISE AFFECT THE PRICE OF THE TRUST

SECURITIES TO COVER SYNDICATE SHORT POSITIONS, AND IMPOSING PENALTY BIDS. FOR

                               ---------------
(Continued from previous page)
 
  Holders of the Trust Securities will be entitled to receive, to the extent
of funds held by the Trust and available therefor, periodic cash distributions
accumulating from the date of original issuance and payable quarterly in
arrears on March 31, June 30, September 30 and December 31 of each year,
commencing    , 1998, at the rate of  % per annum of the liquidation amount of
$25 per Trust Security (the "Distributions"). So long as no Event of Default
(as defined under "Description of the Junior Subordinated Debentures--
Indenture Event of Defaults") under the Indenture (as defined under "Summary--
The Offering") has occurred and is continuing, Yorkshire Finance has the right
to defer the payment of interest ("Interest Payments") on the Junior
Subordinated Debentures at any time or from time to time, for up to 20
consecutive quarters (each an "Extension Period"). An Extension Period,
however, cannot extend beyond the Stated Maturity (as defined below) of the
Junior Subordinated Debentures. If Interest Payments on the Junior
Subordinated Debentures are so deferred, Distributions on the Trust Securities
will also be deferred. Until all deferred Interest Payments and interest
thereon have been paid in full, Interest Payments on the Junior Subordinated
Debentures will continue to accrue (and the Trust Securities will accumulate
additional Distributions thereon) at the rate of    % per annum, compounded
quarterly. During any Extension Period, holders of Trust Securities will be
required to accrue deferred interest as original issue discount ("OID"), and
to include such OID in their gross income for US Federal income tax purposes
in advance of the receipt of the cash distributions with respect to such
deferred Interest Payments. There could be multiple Extension Periods of
varying lengths throughout the term of the Junior Subordinated Debentures.
During an Extension Period, neither Yorkshire Finance nor Yorkshire Group will
be permitted, subject to certain exceptions set forth herein, to (i) declare
or pay any cash distributions with respect to its capital stock, (ii) make any
payments on its debt securities that rank pari passu with or junior to the
Junior Subordinated Debentures or the Debentures Guarantee, respectively,
(iii) make any payments with respect to any guarantee that ranks pari passu
with or junior to the Junior Subordinated Debentures or the Debentures
Guarantee, respectively, or (iv) make any payments on its debt securities held
by, make any loans or advances to, or make payments with respect to any
guarantee of the debt of, any affiliate. See "Description of the Junior
Subordinated Debentures--Option to Defer Payment of Interest". During an
Extension Period, Yorkshire Group's obligations to make payments under the
Trust Securities Guarantee and the Debentures Guarantee will be suspended.
 
  Pursuant to the Trust Securities Guarantee, Yorkshire Group will guarantee
the payment of Distributions and payments on liquidation of the Trust or
redemption of the Trust Securities, but only in each case to the extent of
sufficient funds held by the Trust and available therefor. If Yorkshire
Finance does not make payments of principal of or interest on the Junior
Subordinated Debentures or Yorkshire Group does not make payments pursuant to
the Debentures Guarantee, the Trust will have insufficient funds to pay
Distributions on the Trust Securities or amounts payable on redemption thereof
or otherwise. The Trust Securities Guarantee does not cover payment of
Distributions or amounts when the Trust does not have sufficient funds
available to pay such amounts. See "Description of the Trust Securities
Guarantee". In such event, the remedy of a holder of Trust Securities will be
to enforce its rights under the Debentures Guarantee. See "Description of the
Junior Subordinated Debentures" and "Description of the Debentures Guarantee".
 
  The Junior Subordinated Debentures will be unsecured and subordinate
obligations and junior in right of payment to all Senior Debt (as defined
under "Description of the Junior Subordinated Debentures--Subordination") of
Yorkshire Finance. The Trust Securities Guarantee and the Debentures Guarantee
will be unsecured and subordinate obligations and junior in right of payment
to all Senior Debt of Yorkshire Group and the Trust Securities Guarantee will
rank pari passu (equal in priority) with the most senior preferred stock of
Yorkshire Group. As of December 31, 1997, Yorkshire Group had (i)
approximately (Pounds)1,034 million ($1,699 million) of Senior Debt
outstanding, a portion of which will be repaid with proceeds of this offering
and (ii) no senior preferred stock outstanding with which the Trust Securities
Guarantee would rank pari passu. The terms of the Junior Subordinated
Debentures and the Trust Securities Guarantee and the Debentures Guarantee
will not place any limitation on the amount of Senior Debt that may be
incurred by Yorkshire Finance and Yorkshire Group, respectively. In addition,
Yorkshire Group's obligations under the Debentures Guarantee and the Trust
Securities Guarantee will be effectively subordinated to all existing and
future
 
                                       2

indebtedness and liabilities of its subsidiaries, including Yorkshire
Electricity Group plc ("Yorkshire"). At December 31, 1997, the direct and
indirect subsidiaries of Yorkshire Group had total indebtedness (excluding
indebtedness owed to Yorkshire Group) of approximately (Pounds)476 million
($782 million). See "Risk Factors", "Description of the Junior Subordinated
Debentures--Subordination", "Description of the Debentures Guarantee" and
"Description of the Trust Securities Guarantee".
 
  AEP Resources, Inc., an Ohio corporation ("AEP Resources"), and New Century
International, Inc., a Delaware corporation ("New Century International" and,
with AEP Resources, collectively, the "US Affiliates"), will unconditionally
guarantee certain expenses and liabilities of the Trust (other than
obligations of the Trust to pay the holders of the Trust Securities the
amounts due such holders pursuant to the terms of the Trust Securities)
pursuant to the Agreement as to Expenses and Liabilities (as defined under
"Description of the Trust Securities Guarantee--The Agreement as to Expenses
and Liabilities"). See "Description of the Trust Securities Guarantee--The
Agreement as to Expenses and Liabilities". The Trust Securities Guarantee, the
Debentures Guarantee, the Indenture, the Junior Subordinated Debentures, the
Trust Agreement (as defined under "Summary--The Offering") and the Agreement
as to Expenses and Liabilities when taken together, will effectively provide a
full and unconditional guarantee, on a subordinated basis, of the Trust's
obligations under the Trust Securities. See "Relationship Among the Trust
Securities, the Junior Subordinated Debentures, the Trust Securities Guarantee
and the Debentures Guarantee".
 
  The Trust Securities are subject to mandatory redemption, in whole or in
part, upon redemption of the Junior Subordinated Debentures in an amount equal
to the aggregate principal amount of Junior Subordinated Debentures being
redeemed at a price equal to the aggregate liquidation amount of such Trust
Securities plus accumulated and unpaid Distributions thereon to the date fixed
for redemption (the "Redemption Price"). The Trust Securities will also be
redeemed in whole at the Redemption Price at the Stated Maturity of the Junior
Subordinated Debentures. See "Description of the Trust Securities--
Redemptions". The Junior Subordinated Debentures will mature on         , 2038
(the "Stated Maturity"). The Junior Subordinated Debentures are redeemable at
the option of Yorkshire Finance (i) on or after     , 2003, in whole at any
time or in part from time to time, at a price equal to the accrued and unpaid
interest on the Junior Subordinated Debentures so redeemed to the date fixed
for redemption plus 100% of the aggregate principal amount thereof (the
"Debenture Redemption Price"), (ii) at any time, in whole (but not in part),
upon the occurrence and continuation of a Special Event (as defined under
"Description of the Trust Securities--Redemptions"), at the Debenture
Redemption Price or (iii) at any time, in whole (but not in part), if
Yorkshire Finance or Yorkshire Group has or will become obligated to pay
Additional Amounts (as defined under "Summary--The Offering"), as provided
under "Description of the Junior Subordinated Debentures--Optional Tax
Redemption", at the Debenture Redemption Price.
   
  At any time, the Control Party (as defined under "Summary--The Offering"),
as the holder of the Control Certificate (as defined under "Summary--The
Offering") of the Trust, will have the right to dissolve the Trust and, after
satisfaction of liabilities to creditors of the Trust, if any, as provided by
applicable law, cause a Like Amount (as defined under "Description of the
Trust Securities--Redemptions") of Junior Subordinated Debentures to be
distributed to the holders of the Trust Securities in liquidation of the
Trust. See "Description of the Trust Securities--Distribution of Junior
Subordinated Debentures".     
 
  In the event of the dissolution and liquidation of the Trust, after
satisfaction of liabilities to creditors of the Trust, if any, as provided by
applicable law, the holders of the Trust Securities will receive a Like Amount
of Junior Subordinated Debentures unless, in certain circumstances, such
distribution is determined not to be practical, in which event holders will be
entitled to receive a liquidation amount of $25 per Trust Security plus
accumulated and unpaid Distributions thereon to the date of payment. See
"Description of the Trust Securities--Liquidation Distribution upon
Dissolution".
 
  In addition to applying to list the Trust Securities on the NYSE,
application will be made to list the Junior Subordinated Debentures on the
Luxembourg Stock Exchange. If the Junior Subordinated Debentures are
distributed to the holders of the Trust Securities upon the liquidation of the
Trust, Yorkshire Finance will use its best efforts to also list the Junior
Subordinated Debentures on the NYSE or such other stock exchanges or other
organizations, if any, on which the Trust Securities are then listed.
 
  The Trust Securities will be represented by global certificates registered
in the name of a nominee of DTC. Beneficial interests in the Trust Securities
will be shown on, and transfers thereof will be effected only through, records
maintained by Participants (as defined under "Description of the Trust
Securities--Book-Entry Issuance") in DTC. Except as described under
"Description of the Trust Securities--Book-Entry Issuance", Trust Securities
in definitive form registered in the names of the beneficial owners thereof
will not be issued in exchange for the global certificates.

  Yorkshire Group, Yorkshire Finance and the Trust, collectively, have filed
with the Commission a registration statement on Form S-1 (herein, together
with all amendments and exhibits thereto, referred to as the "Registration
Statement") under the Securities Act of 1933, as amended (the "Securities
Act"). This Prospectus does not contain all of the information set forth in
the Registration Statement, certain parts of which are omitted in accordance
with the rules and regulations of the Commission. For further information,
reference is hereby made to the Registration Statement.
 
  No separate financial statements of Yorkshire Finance or the Trust have been
included herein. Yorkshire Group does not consider that such financial
statements would be material to holders of the Trust Securities because
Yorkshire Finance and the Trust are newly formed special purpose entities,
have no operating history or independent operations and are not engaged in and
do not propose to engage in any activity other than acting as financing
subsidiaries of Yorkshire Group and its affiliates. See "Summary", "Yorkshire
Capital Trust I", "Description of the Trust Securities", "Description of the
Junior Subordinated Debentures", "Description of the Trust Securities
Guarantee" and "Description of the Debentures Guarantee". In addition,
Yorkshire Group does not expect that the Trust or Yorkshire Finance will file
reports, proxy statements and other information under the Exchange Act with
the Commission.
 
                      ENFORCEABILITY OF CIVIL LIABILITIES
 
  Yorkshire Group is a private company with limited liability incorporated
under the laws of England and Wales. Yorkshire Finance is a limited liability
company incorporated under the laws of the Cayman Islands. Substantially all
the assets of Yorkshire Group and Yorkshire Finance 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 Yorkshire Group and
Yorkshire Finance or to enforce against it judgments of US courts predicated
upon civil liabilities under US Federal securities laws. There is doubt as to
the enforceability in England and the Cayman Islands, in original actions or
in actions for enforcement of judgments of US courts, of civil liabilities
predicated upon US Federal securities laws.
 
  The Trust Agreement and the Trust Securities will be governed by, and
construed in accordance with, the laws of the State of Delaware. The Trust
Securities Guarantee, the Debentures Guarantee, the Indenture and the Junior
Subordinated Debentures will be governed by, and will be construed in
accordance with, the laws of the State of New York. Yorkshire Group and
Yorkshire Finance have 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 legal suit, action or proceeding against Yorkshire
Group and Yorkshire Finance or their properties, assets or revenues with
respect to their obligations, liabilities or any other matter arising out of
or in connection with the Trust Securities Guarantee, the Debentures
Guarantee, the Indenture and the Junior Subordinated Debentures. See
"Description of the Junior Subordinated Debentures--Governing Law; Submission
to Jurisdiction".

                                    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.
 
                         YORKSHIRE POWER GROUP LIMITED
 
  Yorkshire Group was incorporated as a private company with limited liability
under the laws of England and Wales in July 1996 and is indirectly owned by
American Electric Power Company, Inc. ("AEP") and New Century Energies, Inc.
("NCE" and, together with AEP, the "US Parents"). Each of the US Parents
indirectly owns 50% of the outstanding shares of the Yorkshire Group. In 1997,
Yorkshire Group was utilized in connection with the joint acquisition of
Yorkshire by the US Parents for approximately (Pounds)1.5 billion (the
"Acquisition"). Yorkshire Group holds all the outstanding shares of Yorkshire
Holdings plc ("Yorkshire Holdings"), which is its primary asset. Yorkshire
Holdings, in turn, beneficially owns all the outstanding shares of Yorkshire.
See "Yorkshire Group and the US Parents".
 
                        YORKSHIRE POWER FINANCE LIMITED
 
  Yorkshire Finance, a subsidiary of Yorkshire Group, was incorporated as a
company with limited liability under the laws of the Cayman Islands in August
1997. Yorkshire Finance exists solely for the purpose of operating as a
financing vehicle for Yorkshire Group and its affiliates. See "Yorkshire Group
and the US Parents".
 
                        YORKSHIRE ELECTRICITY GROUP PLC
 
  Yorkshire is one of twelve regional electricity companies ("RECs") in England
and Wales licensed to distribute, supply and, to a limited extent, generate
electricity. Yorkshire's two principal businesses are the "distribution
business" and the "supply business". Yorkshire's distribution business consists
of the distribution of electricity to approximately two million residential,
commercial and industrial customers in its Franchise Area. Substantially all of
the distribution business is a regulated monopoly. Yorkshire's supply business
consists of the purchase and supply of electricity primarily to customers
within the Franchise Area.
 
  Yorkshire generated total operating income of (Pounds)52 million ($85
million) in Fiscal Year 1997. During Fiscal Year 1997, however, Yorkshire
recorded a (Pounds)78 million ($128 million) provision for uneconomic gas and
electricity contracts and a (Pounds)50 million ($82 million) charge for
information system development costs to prepare for the opening of the
competitive electricity market in 1998 for Franchise Supply Customers (as
defined below). Excluding these charges, total operating income would have been
(Pounds)180 million ($295 million) in Fiscal Year 1997, including (Pounds)140
million ($230 million) (78% of total) associated with the core distribution
business and (Pounds)29 million ($48 million) (16% of total) associated with
the supply business. As discussed below under "Business--Business
Restructuring", beginning in 1998, Yorkshire will operate the distribution and
supply businesses as self-sufficient businesses.
 
  Yorkshire is authorized under its Public Electricity Supply License (the "PES
License") to distribute and supply electricity in an area covering
approximately 10,000 square km (3,860 square miles), which encompasses the
counties of West Yorkshire, East Yorkshire and almost all of South Yorkshire,
together with parts of North Yorkshire, Derbyshire, Nottinghamshire,
Lincolnshire and Lancashire (the "Franchise Area"). The resident population of
the Franchise Area served by Yorkshire is approximately 4.4 million. The
regional economy is diverse, including traditional heavy industries such as
iron, steel and coal mining, as well as growing service
 
                                       7

sector activities such as finance, retailing and leisure. Centrally located in
the UK, the region is also well served by roads, railways, airports and ports
which provide access to other European markets.
 
  Pursuant to its PES License, Yorkshire owns, manages and operates the
electricity distribution network within the 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 connected
to Yorkshire's distribution network. Since the distribution business is
substantially a regulated monopoly, virtually all electricity supplied (whether
by Yorkshire's supply business or by any other suppliers) to consumers within
the Franchise Area is transported through Yorkshire's distribution network.
Yorkshire Group believes that economic, environmental and regulatory factors
are likely to prevent competitors from entering the distribution business in
the Franchise Area. See "Business--Distribution Business" and "--Business
Restructuring".
 
  Yorkshire's supply business consists of selling electricity to end users and
purchasing such electricity and arranging for its distribution to those end
users. Within the Franchise Area, Yorkshire has an exclusive right to supply
electricity to consumers who, within the most recent twelve-month period, have
had an average peak demand ("Peak Demand") of not more than 100 kW in the three
months of highest maximum demand during such period ("Franchise Supply
Customers"). This exclusive right will continue until September 1998 when the
supply market for these customers is currently scheduled to become competitive
over a six-month phase-in period. The supply of electricity to Non-Franchise
Supply Customers (as defined below) is currently open to competition and
Yorkshire is able to competitively bid or negotiate to supply electricity to
such customers. By purchasing electricity at competitive rates from most of the
major power generators in the UK and providing high quality customer service,
Yorkshire has been able to sustain its position as one of the largest national
suppliers of electricity. "Non-Franchise Customers" are consumers, both inside
and outside of Yorkshire's Franchise Area, who, within the most recent twelve
month period, have had an average Peak Demand of more than 100 kW in the three
months of highest maximum demand during such period. See "Business--Supply
Business" and "--Business Restructuring".
 
  The operations of Yorkshire are regulated under its PES License, pursuant to
which income generated by Yorkshire's distribution business and income derived
from Franchise Supply Customers are subject to a price cap regulatory framework
providing economic incentives to operate in a cost-effective manner, and, to a
limited extent, to increase the volume of electricity distributed. See "The
Electric Utility Industry in Great Britain".
 
  Yorkshire also conducts ancillary business activities apart from the
distribution and supply businesses that are not subject to price regulation,
such as owning an interest in an off-shore gas field, supplying gas in the
competitive market and holding interests in power generation. See "Business--
Affiliate Businesses and Other Investments" and "--Business Restructuring".
 
                           YORKSHIRE CAPITAL TRUST I
 
  The Trust is a statutory business trust created under the Delaware Business
Trust Act (the "Delaware Act") pursuant to the filing of a certificate of trust
with the Delaware Secretary of State on February 4, 1998. The Trust exists for
the exclusive purposes of (i) issuing and selling the Trust Securities
representing undivided beneficial interests in the assets of the Trust, (ii)
investing the gross proceeds of the Trust Securities in the Junior Subordinated
Debentures and (iii) engaging in only those other activities necessary,
appropriate, convenient or incidental thereto. See "Yorkshire Capital Trust I".

                              defined under "Description of the Trust

                              business on the 15th calendar day prior to such

Ratings.....................     
                              The Trust Securities are expected to be assigned
                              ratings of BBB by Standard & Poor's Ratings
                              Services ("S&P"), BBB by Duff & Phelps Credit
                              Rating Company ("DCR") and "baa2" by Moody's
                              Investors Service, Inc. ("Moody's"). These
                              ratings will have been obtained with the
                              understanding that S&P, DCR and Moody's will
                              continue to monitor the credit rating of the
                              registrants 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 Trust Securities. 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.
                                  
Deferral of Interest          So long as no Event of Default under the
Payments....................  Indenture has occurred and is continuing,
                              Yorkshire Finance has the right to defer Interest
                              Payments on the Junior Subordinated Debentures,
                              at any time or from time to time, for up to 20
                              consecutive quarters; provided, however,
                              Yorkshire Finance cannot defer Interest Payments
                              beyond the Stated Maturity of the Junior
                              Subordinated Debentures. If Interest Payments on
                              the Junior Subordinated Debentures are so
                              deferred, Distributions on the Trust Securities
                              will also be deferred. During an Extension
                              Period, Yorkshire Group's obligations to make
                              payments under the Trust Securities Guarantee and
                              the Debentures Guarantee will be suspended. See
                              "Description of the Junior Subordinated
                              Debentures--Option to Defer Payment of Interest".

Ranking of Junior
Subordinated Debentures and
Debentures Guarantee........
                              The Junior Subordinated Debentures and the
                              Debentures Guarantee will be unsecured and
                              subordinated obligations of Yorkshire Finance and
                              Yorkshire Group, respectively, and will be junior
                              in right of payment to all Senior Debt of
                              Yorkshire Finance and Yorkshire Group,
                              respectively, to the extent and in the manner set
                              forth in the Indenture. At December 31, 1997,
                              Senior Debt of Yorkshire Group aggregated
                              approximately (Pounds)1,034 million ($1,699
                              million), a portion of which will be repaid with
                              proceeds of this offering. Because Yorkshire
                              Group is a holding company, Yorkshire Group's
                              obligations under the Debentures Guarantee will
                              be effectively subordinated to all existing and
                              future indebtedness and liabilities of Yorkshire
                              Group, including Yorkshire. At December 31, 1997,
                              the direct and indirect subsidiaries of Yorkshire
                              Group had total indebtedness (excluding
                              indebtedness owed to Yorkshire Group) of
                              approximately (Pounds)476 million ($782 million).

                              payment to all Senior Debt of Yorkshire Group and
                              will rank pari passu with the most senior
                              preferred stock of Yorkshire Group. At December
                              31, 1997, Yorkshire Group had no senior preferred
                              stock outstanding with which the Trust Securities
                              Guarantee would rank pari passu. See "Risk
                              Factors--Factors Relating to the Trust Securities
                              and the Junior Subordinated Debentures--
                              Subordination of and Limitation of Funds
                              Available to Trust under the Trust Securities
                              Guarantee".
 
                              If Yorkshire Finance does not make payments of
                              principal of or interest on the Junior
                              Subordinated Debentures or Yorkshire Group does
                              not make payments pursuant to the Debentures
                              Guarantee, the Trust will not have sufficient
                              funds to pay Distributions on the Trust
                              Securities or amounts payable on redemption
                              thereof or otherwise. In such event, the Trust
                              Securities Guarantee will not apply to such
                              Distributions of such amounts until the Trust has
                              sufficient funds available therefor. The remedy
                              of a holder of Trust Securities, accordingly,
                              will be to enforce its rights under the
                              Debentures Guarantee.
 
                              Pursuant to the Debentures Guarantee, Yorkshire
                              Group will irrevocably and unconditionally
                              guarantee all payments on the Junior Subordinated
                              Debentures when and as the same shall become

                              will be suspended. See "Description of the Junior

                              together, will effectively provide a full and
                              unconditional guarantee, on a subordinated basis,
                              of the Trust's obligations under the Trust

  The following table sets forth summary consolidated financial data for
Yorkshire Power Group Limited after March 31, 1997 ("Yorkshire Group" or the
"Successor Company") and Yorkshire Electricity Group plc ("Yorkshire" or the
"Predecessor Company") for each of the five Fiscal Years ended March 31, 1997
prepared in accordance with US GAAP. For a description of the financial
statements and records from which the following financial data have been
derived, see "Selected Consolidated Financial Data". This information should be
read in conjunction with "Capitalization", "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and the consolidated
financial statements and notes thereto of the Successor Company and the
Predecessor Company included elsewhere in this Prospectus.
 
  The summary unaudited pro forma consolidated income statement data for the
Successor Company for Fiscal Year 1997 presented below reflect the Acquisition
as if it had occurred as of April 1, 1996. Such data have been prepared by the
Successor Company based upon assumptions deemed proper in accordance with the
purchase method of accounting for business combinations and have been adjusted
to reflect (i) interest expense of (Pounds)74 million incurred as a result of
the financing of the Acquisition, (ii) amortization of (Pounds)24 million
related to goodwill recorded in connection with the Acquisition, (iii)
additional depreciation expense of (Pounds)6 million as a result of the
revaluation of certain fixed assets in connection with the Acquisition and (iv)
removal of the effect of recording the provision of (Pounds)78 million of
certain uneconomic gas and electricity contracts, the loss of (Pounds)7 million
on certain interest rate swap agreements and the write-down of (Pounds)6
million relating to non-operational property. Such data are shown for
illustrative purposes only and are not necessarily indicative of the future
results of operations of the Successor Company or of the results of operations
of the Successor Company that would have actually occurred had the Acquisition
occurred at the beginning of the period presented. Such data should be read in
conjunction with the unaudited pro forma consolidated statement of income and
notes thereto of the Successor Company included elsewhere in this Prospectus.

(1) Notable operating expenses include:
  Fiscal Year 1997--(i) a provision of (Pounds)78 million for uneconomic gas
  and electricity contracts (the effect of which is removed from the
  Successor Company's unaudited pro forma consolidated statement of income
  for Fiscal Year 1997), which resulted in a charge of (Pounds)125 million to
  the supply business offset by an intrabusiness elimination of (Pounds)47
  million and (ii) a charge of (Pounds)50 million for information system
  development costs to prepare for the opening of the competitive electricity
  market in 1998 for Franchise Supply Customers, of which (Pounds)37 million
  was charged to the supply business and (Pounds)13 million was charged to
  the distribution business.
  Fiscal Years 1993, 1994 and 1995--reorganization costs of (Pounds)18
  million, (Pounds)44 million and (Pounds)8 million, respectively.
(2) Other income (loss) principally represents income from Yorkshire's
    investment in National Grid Group plc ("NGG") and, in Fiscal Year 1996, a
    gain resulting from the NGG Transaction (as defined herein) and earnings
    and losses from Yorkshire's investments in joint ventures and minority
    holdings. Notable items include:
  Fiscal Year 1997--gain on sale of Yorkshire's investment in Torch Telecom
  of (Pounds)15 million.
 
  Fiscal Year 1996--income from investment in NGG and gain in respect of the
  NGG Transaction as described under "Management's Discussion and Analysis of
  Financial Condition and Results of Operations--Introduction--NGG
  Transaction".
 
  Fiscal Year 1995--one-time termination payment received from Stockholm
  Stadhus AB of (Pounds)17 million.
 
  Fiscal Year 1994--loss on sale of Yorkshire's investment in Homepower
  Retail Limited of (Pounds)18 million.
 
(3) Fiscal Year 1996 includes a tax charge of (Pounds)38 million relating to
    the NGG Transaction.
(4) EBIT represents income before the sum of interest expense and income taxes.
    EBITDA represents income before the sum of interest expense, income taxes,
    depreciation and amortization. EBIT and EBITDA are provided for
    informational purposes only and such measures should not be construed as
    alternatives to operating income (as determined in accordance with US GAAP)
    as indicators of operating performance, or as alternatives to cash flows
    from operating activities (as determined in accordance with US GAAP) as
    measures of liquidity. EBIT and EBITDA are widely accepted financial
    indicators of a company's ability to incur and service debt. However, the
    measures of EBIT and EBITDA presented herein may not be comparable to
    similar measures presented by other companies.
(5) The ratio of earnings to fixed charges is computed as the sum of pre-tax
    income (before extraordinary item), plus fixed charges divided by fixed
    charges. Fixed charges consist of interest expense and amortization of debt
    expense.
(6) Solely for the convenience of the reader, pounds sterling amounts have been
    translated into US dollar amounts at the Noon Buying Rate on December 31,
    1997 of $1.64 = (Pounds)1. See "Presentation of Certain Information and
    Exchange Rates".
(7) Represents the windfall tax imposed by the UK government, which was not
    deductible for UK corporation tax purposes.
(8) Intrabusiness eliminations consist primarily of intracompany transactions
    between the distribution business and the supply business and interbusiness
    transactions between ancillary businesses. Pursuant to the UK regulatory
    framework, charges by the distribution business for electricity in respect
    of supply customers in the Franchise Area are billed to the supply
    business, which in turn incorporates the distribution charge into the bill
    sent to the final end user.

                                 RISK FACTORS
 
  In addition to the other information in this Prospectus, the following
factors should be considered carefully in evaluating an investment in the
Trust Securities.
 
FACTORS RELATING TO YORKSHIRE'S BUSINESS
 
 Substantial Leverage
 
  Upon completion of this offering, Yorkshire Group will continue to have
substantial indebtedness. At December 31, 1997 (after the effect of the
windfall tax on shareholder's equity), on a pro forma basis after giving
effect to the Senior Notes and the Guaranteed Eurobonds (each as defined under
"Capitalization"), both issued in February 1998, and the issuance of the Trust
Securities offered hereby, the ratio of Yorkshire Group's consolidated debt to
total capitalization was approximately 73%. See "Capitalization". The degree
to which Yorkshire Group is leveraged could affect its ability to service its
indebtedness, to make capital investments, to take advantage of certain
business opportunities, to respond to competitive pressures or to obtain
additional financing. Yorkshire Group believes that, following this offering,
it will be able to make payments on its obligations (including its obligations
under the Trust Securities Guarantee and the Debentures Guarantee) with those
funds subsequently being made available to make payments of principal of and
interest on the Junior Subordinated Debentures and the Trust Securities, as
applicable, from funds derived from the operations of Yorkshire and its
subsidiaries. The ability of Yorkshire Finance to pay amounts due on the
Junior Subordinated Debentures is solely dependent upon Yorkshire Group making
payments to Yorkshire Finance as and when required.
 
  Unexpected declines in Yorkshire's future business, especially in light of
the increasingly competitive environment in the UK electric and gas utility
industries, increases in operating or capital costs, or the inability to
borrow additional funds, could impair Yorkshire Group's ability to meet its
debt service obligations, and, therefore, could adversely affect Yorkshire
Finance's ability to make payments of principal of and interest on the Junior
Subordinated Debentures and, ultimately, the Trust's ability to make payments
on the Trust Securities. No assurance can be given that additional financing
will be available when needed, or, if available, will be obtainable on terms
that are favorable to Yorkshire Group or Yorkshire Finance.
 
 Price Regulation of the Distribution Business
 
  The distribution business of Yorkshire is regulated under its PES License
pursuant to which charges by the distribution business to its customers are
controlled by the Distribution Price Control Formula (as defined under "The
Electric Utility Industry in Great Britain--Distribution of Electricity"). The
Distribution Price Control Formula determines the maximum allowable average
price per unit of electricity (expressed in kWh, a "unit") that a PES License
holder may charge in any year. The elements used in the Distribution Price
Control Formula (which includes the UK Retail Price Index) are established for
a five year period and are subject to review by the Director General of
Electricity Supply for the UK (the "Regulator") at the end of each five year
period and at other times at the discretion of the Regulator. At each review,
the Regulator can adjust the value of certain elements in the Distribution
Price Control Formula.
 
  Following a review by the Regulator in July 1994, a 14% below inflation
price reduction was set for Yorkshire's allowed distribution revenues
effective April 1, 1995. Such adjustment was the principal reason for the
reduction of Yorkshire's distribution operating revenues to (Pounds)334
million ($548 million) for Fiscal Year 1996 from (Pounds)362 million ($594
million) for Fiscal Year 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 of Yorkshire's distribution prices, a further
13% below inflation reduction became effective April l, 1996 with a further 3%
below inflation reduction effective in each of the three following years. This
review was the principal reason for the reduction in distribution operating
revenues for Fiscal Year 1997 to (Pounds)308 million ($505 million). There can
be no assurance that any future review by the Regulator, the next of which is
scheduled for 2000, will not adversely affect Yorkshire. See "The Electric
Utility Industry in Great Britain--Distribution of Electricity--Price
Control".
 
 Competition in and Price Regulation of the Supply Business
 
  Each PES License holder currently has an exclusive right, subject to price
cap regulation, to supply Franchise Supply Customers in its franchise area.
However, the supply market is being progressively opened to
 
                                      20
<PAGE>
 
full competition. The market for customers with a Peak Demand above 1 MW has
been open to competition for suppliers of electricity since privatization in
1990 while, for Non-Franchise Supply Customers, the market became competitive
in April 1994. The final stage of this process is currently scheduled to occur
over a period of six months commencing September 1998, when competition in the
supply of Franchise Supply Customers will be fully phased in and the exclusive
right to supply Franchise Supply Customers is scheduled to end. Yorkshire's
strategy to meet expanded competition in its supply business will focus on
active marketing and customer service to protect and sustain its position in
the electricity market in its Franchise Area. Furthermore, Yorkshire will seek
to expand market share outside its Franchise Area to the extent that such
business is profitable. There can be no assurance that this strategy will be
successful in avoiding loss of existing customers, or achieving gains of new
customers of Yorkshire's supply business. See "Business--Supply Business" and
"--Business Restructuring".
 
  In October 1997, the Regulator published proposals for new transitional
supply price restraints to apply from April 1, 1998 to residential and small
business customers for an initial period of two years and until an adequate
level of competition is established. Yorkshire subsequently indicated its
acceptance of such proposals. The proposals (when taken together with the
reduction in the Fossil Fuel Levy (as defined under "The Electric Utility
Industry in Great Britain--Fossil Fuel Levy"), which became effective on April
1, 1998) resulted in the implementation of small reductions, also effective
April 1, 1998, in the tariffs for Yorkshire's residential and small business
customers in its Franchise Area compared to the corresponding tariffs in
effect in August 1997. The proposals also require an additional 3% below
inflation reduction effective April 1, 1999. See "The Electric Utility
Industry in Great Britain--Supply of Electricity--Price Regulation".
 
  The license modifications that have been implemented to effect the new
controls also discontinued the automatic pass-through of all costs currently
passed through to residential and small business customers, consisting
primarily of purchased power costs. This change will increase the importance
to Yorkshire of effective power purchasing and hedging activities. See "--Pool
Purchase Price Volatility; Hedging Activities", "The Electric Utility Industry
in Great Britain--Supply or Electricity--Price Regulation" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations".
 
  The transition to competition in supply with respect to Franchise Supply
Customers requires each REC to provide additional data management services to
all suppliers. Assuming that such competition starts as currently scheduled in
September 1998 for Franchise Supply Customers, Yorkshire Group presently
estimates that costs totalling (Pounds)75 million will have been incurred for
re-engineering and information technology work. Of such amount, approximately
(Pounds)19 million was expensed in Fiscal Year 1997. The Regulator has made
proposals (which have been accepted by Yorkshire) to allow Yorkshire recovery
of (Pounds)23 million over a five year period ending March 31, 2003. A further
(Pounds)7 million is expected to be recovered through Pool cost recovery and
other national mechanisms and (Pounds)8 million is expected to be capitalized
as such amount is expected to provide future benefits to the supply business.
As a result of the above, the residual amount of approximately (Pounds)18
million, which will not be recovered or capitalized, will be expensed in
Fiscal Years 1998 and 1999 as incurred.
 
  The Regulator has also made proposals (which have been accepted by
Yorkshire) to provide an annual allowance of (Pounds)3 million for the period
1998 through 2000 to cover operating costs. This allowance will be reviewed at
the time of the Distribution Price Control Formula review in 2000.
 
  The October 1997 proposals therefore will allow Yorkshire to recover up to
50% of its forecasted set-up and operating costs over a five year period. The
shortfall could be higher if: (i) operating costs are higher than anticipated
(e.g., there is a higher level of customer activity); (ii) recovery of
operating costs is disallowed or reduced when the Distribution Price Control
Formula is reviewed for the period beginning April 1, 2000; or (iii) the
integrated national systems do not work as contemplated or require substantial
redevelopment.
 
  The Regulator's proposals also provide that a REC should be penalized (i)
where it starts to open its market more than three months after the market
opening by the first REC; (ii) where it opens successive tranches of its
market more than three months after the opening of the corresponding tranche
by the first REC; and (iii) where the market opening of the first REC has been
delayed beyond April 1, 1998. The penalties will be calculated at
 
                                      21
<PAGE>
 
1% of the operating revenues of the supply business per month of delay,
weighted by the proportion of customers affected and applied as a reduction in
allowed distribution business income. If Yorkshire did not open its market for
Franchise Supply Customers to competition until after April 1, 1999, it would
incur a penalty of approximately (Pounds)6 million. It is now apparent that
some penalty will be incurred due to the delay in the opening of the
competitive market for Franchise Supply Customers until September 1998.
Yorkshire Group expects that Yorkshire will be prepared to open its Franchise
Area to competition in September 1998.
 
 Regulatory Policies Affecting Yorkshire Group
 
  Certain modifications to Yorkshire's PES License following Yorkshire Group's
acquisition of Yorkshire imposed certain conditions designed to assure the
continued financial soundness of Yorkshire, including undertakings which
Yorkshire was required to obtain from AEP and NCE that they will refrain, and
cause their subsidiaries to refrain, from taking any action that would likely
result in Yorkshire breaching its obligations under its PES License and the
Electricity Act 1989 (the "Electricity Act") and an undertaking by Yorkshire
to use reasonable endeavors to maintain an investment grade rating of its debt
securities. Such conditions could have an effect on Yorkshire's dividend
payments which will constitute the principal source of funds for payment of
principal of and interest on the Junior Subordinated Debentures.
 
  On February 24, 1998, following publication of the Monopolies and Mergers
Commission's (the "MMC") report in connection with the proposed
PacificCorp/The Energy Group merger, the Regulator issued a consultation paper
proposing modifications to licenses of public electricity suppliers ("PESs")
which had been subject to takeovers.
 
  The main proposals are:
 
  (1) to allow for a PES generation business to be carried on in an affiliate
      which is not a subsidiary and in such cases for the generation business
      to be conducted outside the scope of the modifications to the PES
      license which have been brought into effect to ensure that the Regulator
      can regulate a company effectively after it has been taken over and to
      help ensure the financial stability of the PES (the "Ring-Fencing
      Conditions");
 
  (2) to restrict further the provisions of existing PES licenses allowing
      PESs to carry out certain otherwise restricted activities provided they
      do not exceed 5 percent of the revenues of the supply, second-tier
      supply and distribution businesses, by introducing an additional test
      based on cumulative investment;
 
  (3) to extend to all PESs that have been acquired the condition contained in
      the licenses of London Electricity plc, Northern Electric plc and
      Yorkshire to use reasonable endeavours to maintain an investment grade
      rating of corporate debt;
 
  (4) to prohibit PESs from accepting "cross-default" provisions in borrowing
      agreements; and
 
  (5) to make the payment of dividends and other distributions by a PES
      expressly conditional on compliance with the Ring-Fencing Conditions in
      the license.
 
  Comments were due with respect to the proposals in the consultation paper by
March 27, 1998. Yorkshire provided comments on the consultation paper on March
25, 1998. In its response, Yorkshire indicated that it did not consider the
proposed modifications described in paragraphs (1), (4) and (5) immediately
above to be necessary. Further proposals are expected to be made by the
Regulator in the light of this consultation paper that may result in further
modifications to PES licenses. There can be no assurance that any such
modifications to Yorkshire's PES License that result from such proposals will
not have a material adverse effect on Yorkshire. See "The Electric Utility
Industry in Great Britain--Regulation under the Electricity Act--Modifications
to Licenses".
 
  The ability of AEP or NCE to contribute additional equity capital to
Yorkshire Group is currently subject to regulation of the Commission under the
Public Utility Holding Company Act of 1935, as amended (the "1935 Act"). The
Commission limits the aggregate amount that either AEP or NCE may invest in
foreign utility companies and exempt wholesale generators to specified
percentages of average consolidated retained earnings at the time an
investment is made. This regulation could delay or limit the making of loans
or the contributions of equity by AEP or NCE to Yorkshire Group to enable
Yorkshire Group to meet its obligations or to contribute additional equity
capital to Yorkshire.

 Governmental Review of Utility Regulation
 
  On June 30, 1997, the new Labour government announced a comprehensive review
of the regulation of the electric, gas, water and telecommunications
industries to be directed by the Department of Trade and Industry. Generally,
the review has focused on whether the current system of regulation in the
utility industries is designed to ensure open and predictable regulation,
fairness to consumers and shareholders and the promotion of a competitive
environment. Particularly, the review has examined whether the current system
of price regulation delivers, over time, the greatest benefits to consumers
while maintaining proper incentives for innovation and investment and an
adequate return to shareholders.
 
  The review culminated, in March 1998, with the publication by the Government
of a Green Paper entitled "A Fair Deal for Consumers: Modernising the
Framework for Utility Regulation" (the "March Green Paper"). The March Green
Paper sets forth a number of proposals of the UK Government designed to
reexamine utility regulation in the UK. Among the main proposals contained
within the March Green Paper are the retention of "RPI-X" as the fundamental
basis for price regulation; increased transparency and consistency of
regulation; the merger of the Office of Electricity Regulation ("OFFER") and
the Office of Gas Regulation ("OFGAS"); the separate licensing of the
distribution and supply businesses of the PESs; amendment of the statutory
duties of utility regulators to provide a new primary duty to exercise their
functions in the manner best calculated to protect the interests of consumers
in the short and long term, wherever possible through promoting competition;
and adopting price regulation to distinguish between income earned through
companies' own efforts and income which results from other factors. Some of
these proposals would require primary legislation. Responses to the March
Green Paper by interested parties have been requested by May 31, 1998.
 
 
  In October 1997, the UK government invited the Regulator to consider
parameters for a review of electricity trading arrangements. Such a review
would focus on the wholesale trading market for electricity within England and
Wales (the "Pool"), trading arrangements outside the Pool and price setting
mechanisms. The review was launched in January 1998 with an announcement that
the Regulator and an independent panel had been asked to report to the Energy
Minister by July 1998. In December 1997, the UK government announced a review
of energy sources for power generation, including fuel diversity, sustainable
development and the role of coal. Representations of interested parties were
submitted in mid-February 1998. While the review is underway, the Secretary of
State has deferred decisions on most outstanding or new applications for the
construction of generating stations. An Energy Select Committee Report on the
Coal Industry issued in April 1998 recommended that such deferral, as it
relates to gas-fired generation, be lifted as soon as possible. The Trade and
Industry Select Committee is undertaking an inquiry into a number of aspects
of UK energy policy. Yorkshire Group cannot predict the results of any of
these reviews or the ultimate effects on Yorkshire or Yorkshire Group. See
"The Electric Utility Industry in Great Britain--Regulation under the
Electricity Act--The Regulator".
 
 Pool Purchase Price Volatility; Hedging Activities
 
  Yorkshire's supply business to Non-Franchise Supply Customers generally
involves entering into fixed price contracts to supply electricity to its
customers. Yorkshire obtains the electricity to satisfy its obligations under
such contracts primarily by purchases from the Pool. See "The Electric Utility
Industry in Great Britain". Because the price of electricity purchased from
the Pool can be volatile (due to the fact the price is set every half hour),
to the extent that Yorkshire purchases electricity from the Pool, Yorkshire 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. Although Yorkshire is currently party to
a series of contracts for differences ("CFDs") (most with terms of twelve
months) that limit such exposure, Yorkshire's ability to manage such risk at
acceptable levels will depend, in part, on the specific terms of the supply
contracts that Yorkshire enters into, Yorkshire's ability to implement and
manage an appropriate hedging strategy and the continued availability of
appropriate hedging instruments. No assurance can be given that this risk will
be effectively mitigated. In addition, under the supply price restraint
proposal published by the Regulator in October 1997 (and accepted by
Yorkshire), costs of power purchases from the Pool and related hedging
activities which
 
                                      23
<PAGE>
 
are currently passed through to residential and small business customers will
no longer be automatically passed through to such customers. See "Business--
Supply Business".
 
 Currency Risks; Hedging Transactions
 
  Yorkshire Group's revenues generated by Yorkshire will be primarily in
pounds sterling while the interest and principal payment obligations with
respect to Junior Subordinated Debentures and the Trust Securities 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 Junior Subordinated Debentures and the Trust
Securities or that increases the effective principal and interest payment
obligations represented by the Junior Subordinated Debentures and the Trust
Securities upon conversion of pounds sterling-based revenues into US dollars
may, if not appropriately hedged, have a material adverse effect on Yorkshire
Group, Yorkshire Finance and the Trust or on their ability to make payments on
the Trust Securities. See "Presentation of Certain Information and Exchange
Rates" for certain information concerning the Noon Buying Rate for pounds
sterling expressed in US dollars. Although Yorkshire Group has entered into
certain transactions to hedge risks associated with exchange rate
fluctuations, there can be no assurance that any such transactions will be
successful in reducing such risks.
 
 Working Capital Deficiency
 
  Yorkshire Group had a working capital deficiency at December 31, 1997 of
(Pounds)1,099 million ($1,805 million), primarily as a result of the initial
financing structure of the Acquisition. This deficiency was largely
attributable to the 1997 Credit Facility (as defined under "Use of Proceeds")
which matures on July 30, 1998. For a discussion of the 1997 Credit Facility,
see Note 11, "Acquisition", to Yorkshire Group's consolidated balance sheet as
of April 1, 1997 included elsewhere in this Prospectus. Yorkshire Group has
partly refinanced the 1997 Credit Facility through the February 1998 issuances
of (Pounds)200 million of Guaranteed Eurobonds due in 2028, (Pounds)213
million of Senior Notes due 2003 and (Pounds)183 million of Senior Notes due
in 2008. It is proposed that the balance of the 1997 Credit Facility be
refinanced through the issuance of (Pounds)168 million of the Trust Securities
offered hereby, the potential issuance of additional senior notes, the
entering into of additional credit facilities, if available and on terms
acceptable to Yorkshire Group, and from the proceeds of the currently
contemplated transfer of Yorkshire Group's generation assets to an entity or
entities other than Yorkshire Group or its subsidiaries. Yorkshire Group is
currently in negotiations with respect to the replacement of the 1997 Credit
Facility. There can be no assurance that the balance of the 1997 Credit
Facility can be refinanced as planned. It is also possible that the terms
under which the balance of the 1997 Credit Facility is refinanced could result
in an increase in Yorkshire Group's financing costs.
 
FACTORS RELATING TO THE TRUST SECURITIES AND THE JUNIOR SUBORDINATED
DEBENTURES
 
 Subordination of and Rights under the Debentures Guarantee
 
  Yorkshire Group is a non-operating holding company, conducting substantially
all of its business through Yorkshire and its subsidiaries. Except to the
extent that Yorkshire Group may receive funds from the US Parents in the
future, Yorkshire Group will rely on dividends, indirectly, from Yorkshire to
meet its corporate expenses and outstanding obligations, including any
payments necessary pursuant to the Debentures Guarantee. Furthermore,
Yorkshire Group's obligations under the Debentures Guarantee will effectively
be subordinated to all existing and future indebtedness and liabilities of the
subsidiaries of Yorkshire Group, including Yorkshire. As a result, the rights
of holders of the Trust Securities, as beneficiaries of the Debentures
Guarantee, in respect of claims on the assets of each of Yorkshire Group's
subsidiaries upon any liquidation or administration are structurally
subordinated to, and therefore will be subject to the prior claims of, the
creditors of Yorkshire and its subsidiaries (including trade creditors),
except to the extent that Yorkshire Group may itself be a creditor with
recognized claims against Yorkshire and its subsidiaries. At December 31,
1997, the direct and indirect subsidiaries of Yorkshire Group had total
indebtedness (excluding indebtedness owed to Yorkshire Group) of approximately
(Pounds)476 million ($782 million).
 
                                      24
<PAGE>
 
  Yorkshire Finance exists solely for the purpose of operating as a finance
vehicle for Yorkshire Group and its affiliates. Accordingly, Yorkshire Finance
will rely on funds from Yorkshire Group and its affiliates to meet its
corporate expenses and outstanding obligations, including payments on the
Junior Subordinated Debentures. If Yorkshire Finance does not receive such
funds from Yorkshire Group or its affiliates and Yorkshire Group does not make
payments pursuant to the Debentures Guarantee, there will not be sufficient
funds to make payments on the Junior Subordinated Debentures. If the Trust, as
holder of the Junior Subordinated Debentures, does not receive such funds, the
Trust will not have sufficient funds to pay Distributions on the Trust
Securities or amounts payable on redemption thereof or otherwise. The Trust
Securities Guarantee does not cover payment of Distributions or any such
amounts when the Trust does not have sufficient funds available to pay such
Distributions. In such event, the remedy of a holder of Trust Securities will
be to enforce its rights under the Debentures Guarantee. The Debentures
Guarantee will be an unsecured and subordinate obligation and junior in right
of payment to all present and future Senior Debt of Yorkshire Group, to the
extent and in the manner set forth in the Indenture. As of December 31, 1997,
Yorkshire Group had approximately (Pounds)1,034 million ($1,699 million)
principal amount of Senior Debt outstanding, a portion of which will be repaid
with proceeds of this offering.
 
  There are no terms of the Trust Securities, the Trust Agreement, the
Indenture, the Junior Subordinated Debentures, the Trust Securities Guarantee
or the Debentures Guarantee that limit Yorkshire Finance's or Yorkshire
Group's ability to incur additional indebtedness, including Senior Debt. See
"Description of the Trust Securities", "Description of the Trust Securities
Guarantee", "Description of the Junior Subordinated Debentures--Subordination"
and "Description of the Debentures Guarantee".
 
 Subordination of and Limitation of Funds Available to Trust under the Trust
Securities Guarantee
 
  The Trust Securities Guarantee will be an unsecured and subordinate
obligation and junior in right of payment to all Senior Debt of Yorkshire
Group and will rank pari passu with the most senior preferred stock issued by
Yorkshire Group. If Yorkshire Finance does not make Interest Payments or other
payments with respect to the Junior Subordinated Debentures or Yorkshire Group
does not make payments pursuant to the Debentures Guarantee, the Trust will
have insufficient funds available to pay Distributions or amounts payable on
redemption thereof or otherwise. In such event, holders of the Trust
Securities would not be able to rely upon the Trust Securities Guarantee for
payment of such amounts. See "Description of the Trust Securities Guarantee".
 
 Option to Defer Payment of Interest; Potential Market Volatility During
Extension Period; Tax Consequences of Deferral
 
  So long as no Event of Default under the Indenture has occurred and is
continuing, Yorkshire Finance has the right under the Indenture to defer
Interest Payments on the Junior Subordinated Debentures, at any time or from
time to time, for up to 20 consecutive quarters; provided, however, Yorkshire
Finance cannot defer Interest Payments beyond the Stated Maturity of the
Junior Subordinated Debentures. During such Extension Period, quarterly
Distributions on the Trust Securities would also be deferred (but would
continue to accumulate additional Distributions thereon) at the rate of    %
per annum, compounded quarterly, by the Trust until all deferred Interest
Payments, together with interest thereon, have been paid in full. Further,
during an Extension Period, Yorkshire Group's obligations to make payments
under the Trust Securities Guarantee and the Debentures Guarantee will be
suspended.
 
  During an Extension Period, neither Yorkshire Finance nor Yorkshire Group
will be permitted, subject to certain exceptions set forth herein, to (i)
declare or pay any cash distributions with respect to its capital stock, (ii)
make any payments on its debt securities that rank pari passu with or junior
to the Junior Subordinated Debentures or the Debentures Guarantee,
respectively, (iii) make any payments with respect to any guarantee that ranks
pari passu with or junior to the Junior Subordinated Debentures or the
Debentures Guarantee, respectively, or (iv) make any payments on its debt
securities held by, make any loans or advances to, or make payments with
respect to any guarantee of the debt of, any affiliate. Prior to the
termination of any such Extension Period, Yorkshire Finance may further extend
the interest payment period; provided that, such
 
                                      25
<PAGE>
 
Extension Period, together with all such previous and further extensions
within such Extension Period, may not exceed 20 consecutive quarters or the
Stated Maturity of the Junior Subordinated Debentures. Upon the termination of
any Extension Period and the payment of all amounts then due, Yorkshire
Finance may commence a new Extension Period, subject to the above
requirements. As a result, there could be multiple Extension Periods of
varying lengths throughout the term of the Junior Subordinated Debentures. See
"Description of the Trust Securities--Distributions" and "Description of the
Junior Subordinated Debentures--Option to Defer Payment of Interest".
 
  In the event Yorkshire Finance exercises its right to defer Interest
Payments on the Junior Subordinated Debentures, the market price of the Trust
Securities is likely to be affected. A holder that disposes of its Trust
Securities during such a deferral, therefore, might not receive the same
return on its investment as a holder that continues to hold its Trust
Securities. In addition, the market price of the Trust Securities may be more
volatile than the market prices of other securities that are not subject to
such deferrals.
 
  In the event Yorkshire Finance exercises its rights to defer Interest
Payments on the Junior Subordinated Debentures, each holder of Trust
Securities will be required to include income in the form of OID in its gross
income for US Federal income tax purposes in respect of the deferred interest
(including interest thereon) allocable to its Trust Securities. As a result, a
holder of Trust Securities will recognize income for US Federal income tax
purposes in advance of the receipt of cash. Such holder will not receive the
cash from the Trust related to such income if such holder disposes of its
Trust Securities prior to the record date for the date on which Distributions
of such amounts are made. Such holder will increase its adjusted basis in its
Trust Securities by the amount of OID so included in income in respect of such
deferral and, to the extent that the adjusted tax basis exceeds the amount
realized on the sale or other disposition of such holder's Trust Securities,
recognize a capital loss. If the holder disposes of a Trust Security prior to
the occurrence of an Extension Period, any portion of the amount received from
the purchaser that is attributable to accrued interest will be treated as
interest income to the holder (that will only be includible as income to the
extent it previously has not been included in the holder's taxable income) and
will not be treated as part of the amount realized for purposes of determining
gain or loss on the disposition of the Trust Security. Subject to certain
limitations, capital losses cannot be applied to offset ordinary income for US
Federal income tax purposes. See "Material Income Tax Considerations--US
Federal Income Tax Considerations--Original Issue Discount" and "--Disposition
of Trust Securities.". INVESTORS SHOULD CONSULT WITH THEIR OWN TAX ADVISORS
WITH RESPECT TO THE TAX CONSEQUENCES OF AN INVESTMENT IN THE TRUST SECURITIES.
 
  Yorkshire Finance currently has no intention of exercising its right to
defer Interest Payments on the Junior Subordinated Debentures. Moreover,
because of the consequences of exercising such right, including a prohibition
on the payment of cash distributions by Yorkshire Finance and Yorkshire Group
with respect to their capital stock, Yorkshire Finance believes the likelihood
of such exercise is remote.
 
 Special Event Redemption; Distribution of Junior Subordinated Debentures
 
  Upon the occurrence and continuation of a Special Event, as described under
"Description of the Trust Securities--Redemptions--Special Event Redemption of
Junior Subordinated Debentures", Yorkshire Finance has the right to redeem the
Junior Subordinated Debentures in whole (but not in part) at the Debenture
Redemption Price, and thereby cause a mandatory redemption of the Trust
Securities, at the Redemption Price, within 90 days following the occurrence
of such Special Event.
   
  In addition, at any time, the Control Party will have the right to dissolve
the Trust and, after satisfaction of liabilities to creditors, if any, of the
Trust as provided by applicable law, cause a Like Amount of Junior
Subordinated Debentures to be distributed to the holders of the Trust
Securities in liquidation of the Trust. See "Description of the Trust
Securities--Distribution of Junior Subordinated Debentures".     
 
  Under current US Federal income tax law, a distribution of Junior
Subordinated Debentures upon a liquidation of the Trust would not be a taxable
event to holders of the Trust Securities. If, however, the Trust
 
                                      26
<PAGE>
 
were characterized for US Federal income tax purposes as an association
taxable as a corporation at the time of such liquidation, the distribution of
the Junior Subordinated Debentures would be a taxable event to holders of
Trust Securities. Under current US Federal income tax law, the redemption of
the Junior Subordinated Debentures upon occurrence of a Special Event or a
liquidation of the Trust in which holders of the Trust Securities receive cash
would be a taxable event to such holders. See "Material Income Tax
Considerations--US Federal Income Tax Considerations--Receipt of Junior
Subordinated Debentures or Cash in Certain Circumstances".
   
  There can be no assurance as to the market prices for the Junior
Subordinated Debentures that may be distributed in exchange for the Trust
Securities if a liquidation of the Trust were to occur. Accordingly, the
Junior Subordinated Debentures that a holder of the Trust Securities may
receive upon liquidation of the Trust could trade at a discount to the price
that the investor paid to purchase the Trust Securities offered hereby.
Because holders of the Trust Securities may receive the Junior Subordinated
Debentures, if the Control Party exercises its right to dissolve the Trust,
prospective purchasers of the Trust Securities are also making an investment
decision with regard to the Junior Subordinated Debentures and the Debentures
Guarantee and should carefully review all the information regarding the Junior
Subordinated Debentures and the Debentures Guarantee contained herein. See
"Description of the Junior Subordinated Debentures--Distribution of the Junior
Subordinated Debentures" and "Description of the Debentures Guarantee".     
 
 No Protection in the Event of a Change in Control, etc.
 
  Neither holders of the Junior Subordinated Debentures nor holders of the
Trust Securities are afforded protection in the event of a highly leveraged
transaction, a change in control or other similar transactions involving
Yorkshire Finance or Yorkshire Group that may adversely affect such holders.
See "Description of the Junior Subordinated Debentures--Consolidation, Merger,
Sale of Assets and Other Transactions".
 
 No Prior Market for the Trust Securities
 
  The Trust Securities constitute a new issue of securities with no
established trading market. Application has been made to list the Trust
Securities on the NYSE. Assuming approval for listing by the NYSE, however,
there can be no assurance that an active market for the Trust Securities will
develop or be sustained in the future. Although the Underwriters have
indicated that they intend to make a market in the Trust Securities, as
permitted by applicable laws and regulations, they are not obligated to do so
and may discontinue any such market making at any time without notice.
Accordingly, no assurance can be given as to the liquidity of the trading
market for the Trust Securities.

                      YORKSHIRE GROUP AND THE US PARENTS
 
YORKSHIRE GROUP
 
  Yorkshire Group was incorporated as a private company with limited liability
under the laws of England and Wales in July 1996. In 1997, Yorkshire Group was
utilized in connection with the Acquisition by the US Parents of Yorkshire,
one of the twelve RECs in England and Wales. Yorkshire Group gained effective
control of Yorkshire on April 1, 1997. Yorkshire Group's primary asset is the
outstanding shares of Yorkshire Holdings, a public limited company
incorporated under the laws of England and Wales, which in turn beneficially
owns all of the outstanding shares of Yorkshire. Yorkshire Holdings was
organized as a wholly-owned subsidiary of Yorkshire Group solely for holding
the share capital of Yorkshire and has no other significant operations.
 
  Each of the US Parents holds an indirect 50% interest in Yorkshire Group.
AEP holds such interest through its wholly-owned subsidiary, AEP Resources.
NCE holds its 50% indirect interest in Yorkshire Group through its wholly-
owned subsidiary, Public Service Company of Colorado, a Colorado corporation,
which in turn wholly-owns New Century International.
 
YORKSHIRE FINANCE
 
  Yorkshire Finance was incorporated under the laws of the Cayman Islands in
August 1997. Yorkshire Finance exists solely for the purpose of operating as a
financing vehicle for Yorkshire Group and its affiliates. Yorkshire Finance
does not, and does not expect to, prepare or publish any financial statements.
The registered office of Yorkshire Finance is P.O. Box 309, George Town, Grand
Cayman Island, British West Indies. The principal executive offices of
Yorkshire Finance are located at Wetherby Road, Scarcroft, Leeds LS14 3HS,
England, telephone number 011-44-113-289-2123.
 
YORKSHIRE
 
  Yorkshire's principal businesses are the distribution of electricity to
approximately two million customers in its Franchise Area and the supply of
electricity primarily within its Franchise Area. Yorkshire generated total
operating income of (Pounds)52 million ($85 million) in Fiscal Year 1997.
During Fiscal Year 1997, however, Yorkshire recorded a (Pounds)78 million
($128 million) provision for uneconomic gas and electricity contracts and a
(Pounds)50 million ($82 million) charge for information system development
costs to prepare for the opening of the competitive electricity market in 1998
for Franchise Supply Customers (as defined herein). Excluding these charges,
total operating income would have been (Pounds)180 million ($295 million) in
Fiscal Year 1997, including (Pounds)140 million ($230 million) (78% of total)
associated with the core distribution business and (Pounds)29 million ($48
million) (16% of total) associated with the supply business. As discussed
below under "Business--Business Restructuring", beginning in 1998, Yorkshire
will operate the distribution and supply businesses as self-sufficient
businesses.
 
  The registered office and principal executive offices of Yorkshire Group and
Yorkshire are located at Wetherby Road, Scarcroft, Leeds LS14 3HS, England,
telephone number 011-44-113-289-2123.
 
THE US PARENTS
 
 AEP
 
  AEP is an electric utility holding company registered under the 1935 Act.
AEP owns all of the outstanding common stock of AEP Generating Company,
Appalachian Power Company, Columbus Southern Power Company, Indiana Michigan
Power Company, Kentucky Power Company, Kingsport Power Company, Ohio Power
Company and Wheeling Power Company. These eight utility subsidiaries are
engaged in the generation, purchase, transmission, distribution and sale of
electricity to over 2.9 million retail customers in portions of the states of
Indiana, Kentucky, Michigan, Ohio, Tennessee, Virginia and West Virginia. AEP
also owns all the outstanding common stock of AEP Resources and AEP Resources
International, Limited whose primary
 
                                      28
<PAGE>
 
businesses are the development of, and investment in, exempt wholesale
generators, foreign utility companies, qualifying cogeneration facilities and
other power projects. In the year ended December 31, 1997, AEP generated
consolidated operating revenues of $6.2 billion and had consolidated assets of
approximately $16.6 billion.
 
  On December 22, 1997, AEP announced the signing of a merger agreement with
Central and South West Corporation, a Dallas, Texas based electric utility
holding company that is registered under the 1935 Act ("CSW"). CSW owns four
electric operating subsidiaries serving 1.7 million customers in Texas,
Oklahoma, Louisiana and Arkansas. CSW also owns SEEBOARD plc, a REC which
serves the southeast coast of England. Under the merger agreement, each share
of CSW common stock will be converted into 0.6 share of AEP common stock.
Based on the price of AEP's common stock on December 19, 1997, the transaction
would be valued at $6.6 billion. The combined company will be named American
Electric Power Company, Inc. and will be based in Columbus, Ohio. The merger
is conditioned upon, among other things, the approvals of the shareholders of
AEP and CSW and various state and federal regulatory agencies. Assuming the
receipt of all required approvals, the merger is currently expected to be
consummated within twelve to eighteen months of its announcement.
 
 NCE
 
  NCE is also an electric utility holding company registered under the 1935
Act. NCE owns all the outstanding common stock of Public Service Company of
Colorado, Cheyenne Light, Fuel and Power Company and Southwestern Public
Service Company, which serve approximately 1.6 million retail electric
customers in portions of the states of Colorado, Texas, New Mexico, Oklahoma,
Kansas and Wyoming and approximately 1 million retail gas customers in
portions of the states of Colorado and Wyoming. These three electric and gas
utility subsidiaries are principally engaged in the generation, purchase,
transmission, distribution and sale of electricity and in the purchase,
transmission, distribution, sale and transportation of natural gas. In the
year ended December 31, 1997, NCE generated consolidated operating revenues of
$3.3 billion and had consolidated assets of approximately $7.3 billion.

                           YORKSHIRE CAPITAL TRUST I
 
  The Trust is a statutory business trust created under Delaware law pursuant
to the filing of a certificate of trust with the Delaware Secretary of State
on February 4, 1998. The Trust's business is defined in a trust agreement,
executed by AEP Resources, as Depositor, The Bank of New York, as Property
Trustee, The Bank of New York (Delaware), as Delaware trustee, and Stephan T.
Haynes, as initial Administrative Trustee thereunder. This trust agreement
will be amended and restated in its entirety prior to the issuance of the
Trust Securities. The Trust exists for the exclusive purposes of (i) issuing
and selling the Trust Securities representing undivided beneficial interests
in the assets of the Trust, (ii) investing the gross proceeds of the Trust
Securities in the Junior Subordinated Debentures and (iii) engaging in only
those other activities necessary, appropriate, convenient or incidental
thereto. The Trust will terminate on     , 2043, but may dissolve earlier, as
provided in the Trust Agreement.
   
  Promptly after its creation, the Trust issued the Control Certificate to AEP
Resources for a nominal amount. AEP Resources transferred such Control
Certificate to Yorkshire Group. Yorkshire Group, in turn, will transfer such
Control Certificate to the Control Party. By holding the Control Certificate,
the Control Party will retain voting control and appointment power with
respect to the Trust. In certain circumstances, the holders of a majority in
liquidation amount of the Trust Securities will be entitled to appoint a
substitute Property Trustee. See "Description of the Trust Securities--Voting
Rights; Amendment of Trust Agreement".     
 
  The Trust's business and affairs will be conducted by the Securities
Trustees. Four employees of the US Parents initially will serve as
Administrative Trustees. The Bank of New York will serve as Property Trustee.
The Bank of New York (Delaware) will serve as Delaware Trustee.
   
  The Property Trustee will hold the Book-Entry Interests (as defined under
"Description of the Junior Subordinated Debentures--Form, Book-Entry
Procedures and Transfer"), representing a 100% beneficial interest in the
Junior Subordinated Debentures, for the benefit of the Trust and the holders
of the Trust Securities and accordingly will have the power to exercise all
rights, powers and privileges under the Deposit Agreement (as defined under
"Description of the Junior Subordinated Debentures--Form, Book-Entry
Procedures and Transfer") and, indirectly, under the Indenture. The Property
Trustee will make payments of Distributions and payments on liquidation,
redemption and otherwise to the holders of the Trust Securities. Subject to
the right of the holders of the Trust Securities to appoint a substitute
Property Trustee in certain instances the Control Party as the holder of the
Control Certificate, will have the right to appoint, remove or replace all the
Securities Trustees.     
   
  The Junior Subordinated Debentures will constitute substantially all of the
assets of the Trust. Other assets that may constitute property of the Trust
include any cash on deposit in, or owing to, the payment account as
established under the Trust Agreement. In addition, the Trust may, from time
to time, receive cash pursuant to the Agreement as to Expenses and
Liabilities.     
 
  The rights of the holders of the Trust Securities, including economic
rights, rights to information and voting rights, are as set forth in the Trust
Agreement, the Delaware Business Trust Act and the Trust Indenture Act of
1939, as amended (the "1939 Act"). See "Description of the Trust Securities".
 
  The principal place of business of the Trust is c/o American Electric Power
Service Corporation, 1 Riverside Plaza, Columbus, Ohio 43215, telephone 614-
223-1000, Attn: Corporate Finance Director.
 
                            US ACCOUNTING TREATMENT
 
  For US financial reporting purposes, the Trust will be treated as a
subsidiary of Yorkshire Group and, accordingly, the accounts of the Trust will
be included in the consolidated financial statements of Yorkshire Group. The
Trust Securities will be presented as a separate line item in the consolidated
balance sheet of Yorkshire Group entitled "Company-Obligated Mandatorily
Redeemable Trust Securities of Subsidiary Holding Solely Junior Subordinated
Deferrable Interest Debentures" and appropriate disclosures about the Trust
Securities, the Trust Securities Guarantee, the Debentures Guarantee and the
Junior Subordinated Debentures will be included in the notes to the
consolidated financial statements. For financial reporting purposes, Yorkshire
Group will record Distributions payable on the Trust Securities as an expense.

<PAGE>
 
                                USE OF PROCEEDS
   
  All of the proceeds from the sale of the Trust Securities will be invested
by the Trust in the Junior Subordinated Debentures issued by Yorkshire Finance
to the Trust. In turn, Yorkshire Finance will loan the net proceeds to
Yorkshire Group and certain of its affiliates with such loans to be evidenced
by the Intercompany Notes. Such proceeds will be used for the working capital
of certain affiliates, and for the repayment of approximately (Pounds)162
million ($265 million) of Yorkshire Group's indebtedness under the Credit
Facility, dated July 31, 1997, between Yorkshire Group and Union Bank of
Switzerland (the "1997 Credit Facility"), which, at December 31, 1997, had an
outstanding balance of (Pounds)1,034 million ($1,699 million) and bore
interest at rates between 7.49% and 7.57%. See "Capitalization" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations".     
 
                                CAPITALIZATION
 
  The following table sets forth, at December 31, 1997 (i) the actual
consolidated capitalization of Yorkshire Group and (ii) the consolidated
capitalization of Yorkshire Group adjusted to reflect (A) the issuance of the
Trust Securities offered hereby and the application of the net proceeds
thereof, as described under "Use of Proceeds", (B) the issuance in February
1998 of (Pounds)200 million ($328 million) aggregate principal amount of
Yorkshire Finance's 7.25% Guaranteed Bonds due 2028 (the "Guaranteed
Eurobonds"), unconditionally and irrevocably guaranteed by Yorkshire Group,
and the application of the net proceeds thereof to reduce amounts outstanding
under the 1997 Credit Facility and (C) the issuance in February 1998 of
$350,000,000 aggregate principal amount of Yorkshire Finance's 6.154% Senior
Notes due 2003 (the "2003 Notes") and $300,000,000 aggregate principal amount
of Yorkshire Finance's 6.496% Senior Notes due 2008 (the "2008 Notes" and,
together with the 2003 Notes, the "Senior Notes"), each series unconditionally
and irrevocably guaranteed by Yorkshire Group, and the application of the net
proceeds thereof to reduce amounts outstanding under the 1997 Credit Facility.
This table should be read in conjunction with "Selected Consolidated Financial
Data", "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and the consolidated financial statements and notes
thereto included elsewhere in this Prospectus.

                     SELECTED CONSOLIDATED FINANCIAL DATA
 
  The consolidated income statement data, other consolidated data and certain
business segment data of the Predecessor Company for each of the five Fiscal
Years ended March 31, 1997 and the consolidated balance sheet data and certain
business segment data of the Predecessor Company at the end of each such
Fiscal Year presented below have been derived from the audited consolidated
financial statements of the Predecessor Company. The consolidated balance
sheet data and certain business segment data of the Successor Company as of
April 1, 1997 presented below have been derived from the audited consolidated
balance sheet of the Successor Company. The consolidated income statement
data, other consolidated data and certain business segment data for the nine
months ended December 31, 1997 and 1996 of the Successor Company and the
Predecessor Company presented below have been derived from the condensed
unaudited consolidated financial statements of the Successor Company and the
Predecessor Company, respectively. The consolidated balance sheet data and
certain business segment data at December 31, 1997 of the Successor Company
presented below have been derived from the condensed unaudited consolidated
financial statements of the Successor Company. In the opinion of the
management of Yorkshire Group, all adjustments (consisting of only normal
recurring adjustments) considered necessary for a fair presentation of the
condensed unaudited consolidated financial statements have been included and
the accompanying condensed unaudited consolidated financial statements present
fairly the financial position and the results of operations for the interim
periods presented. The selected consolidated financial data presented below
that were derived from the audited consolidated financial statements of the
Predecessor Company and the Successor Company have been prepared in accordance
with US GAAP and audited by Deloitte & Touche. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations" and the
consolidated financial statements and notes thereto of the Predecessor Company
and the Successor Company included elsewhere in this Prospectus.
 
  The unaudited pro forma consolidated income statement data for the Successor
Company for Fiscal Year 1997 presented below reflect the Acquisition as if it
had occurred as of April 1, 1996. Such data have been prepared by the
Successor Company based upon assumptions deemed proper in accordance with the
purchase method of accounting for business combinations and have been adjusted
to reflect (i) interest expense of (Pounds)74 million incurred as a result of
the financing of the Acquisition, (ii) amortization of (Pounds)24 million
related to goodwill recorded in connection with the Acquisition, (iii)
additional depreciation expense of (Pounds)6 million as a result of the
revaluation of certain fixed assets in connection with the Acquisition and
(iv) removal of the effect of recording the provision of (Pounds)78 million
for certain uneconomic gas and electricity contracts, the loss of (Pounds)7
million on certain interest rate swap agreements and the write-down of
(Pounds)6 million relating to non-operational property. Such data are shown
for illustrative purposes only and are not necessarily indicative of the
future results of operations of the Successor Company or of the results of
operations of the Successor Company that would have actually occurred had the
Acquisition occurred at the beginning of the period presented. Such data
should be read in conjunction with the unaudited pro forma consolidated
statement of income and notes thereto of the Successor Company included
elsewhere in this Prospectus.

INTRODUCTION
 
 Background
 
  Yorkshire Group is indirectly equally owned by AEP and NCE. Yorkshire Group
was incorporated as a limited company under the laws of England and Wales in
July 1996. Effective April 1, 1997, Yorkshire Group, through its wholly owned
subsidiary Yorkshire Holdings, gained effective control of Yorkshire.
Yorkshire Group's primary asset is the stock of Yorkshire Holdings. Yorkshire
Holdings, which owns all the outstanding stock of Yorkshire, has no
significant operations outside of its investment in Yorkshire.
 
 Financing the Acquisition
 
  Yorkshire Group indirectly acquired ownership of Yorkshire by means of a
cash offer commenced on February 24, 1997 and declared wholly unconditional on
April 1, 1997. The Acquisition was completed through the payment of cash
consideration of (Pounds)1,457 million and the issuance of loan notes in the
amount of (Pounds)22 million. The total consideration, including acquisition
costs, was (Pounds)1,496 million. The Acquisition was financed by cash
contributions of (Pounds)220 million from each of AEP and NCE and from
borrowings under a (Pounds)1,140 million five year term loan and revolving
facility agreement dated February 24, 1997. On July 31, 1997, this term loan
and revolving facility agreement was replaced by the 1997 Credit Facility.
 
 Accounting for the Acquisition
 
  The recorded assets and liabilities of Yorkshire at March 31, 1997 were
(Pounds)1,375 million and (Pounds)1,016 million, respectively. In accordance
with the purchase method of accounting, the assets and liabilities acquired
have been recorded based on an allocation of the purchase price. The final
purchase price allocation report has not yet been completed. However, the
Successor Company does not anticipate any material changes based on currently
available information. Effective April 1, 1997, Yorkshire's assets were
increased by (Pounds)222 million to their fair value of (Pounds)1,597 million,
reflecting principally: (a) an increase of (Pounds)138 million in the value of
Yorkshire's distribution network in excess of its depreciated cost basis; (b)
an increase in the pension asset for the defined benefit pension plan of
(Pounds)55 million; and (c) an increase in the value of an equity investment
in Ionica Group plc ("Ionica") of (Pounds)23 million. Yorkshire's liabilities
were increased by (Pounds)79 million to their fair value of (Pounds)1,095
million, reflecting principally: (a) an increase in the deferred tax liability
of (Pounds)67 million; and (b) an increase of (Pounds)14 million in the market
value of long-term borrowings. The excess of the purchase price plus
Acquisition costs, totalling (Pounds)1,496 million, over the fair value of
assets acquired net of liabilities assumed, totalling (Pounds)502 million,
resulted in goodwill of (Pounds)994 million which is being amortized over a 40
year period. The consolidated financial statements of the Predecessor Company
discussed below do not reflect the foregoing adjustments.
 
 NGG Transaction
 
  During Fiscal Year 1996, Yorkshire, together with the other 11 RECs in the
UK, distributed the majority of its shares in NGG to its shareholders. This
transaction, together with certain related transactions (collectively, the
"NGG Transaction"), had a material impact on Yorkshire's financial results for
that year. The related transactions included: (a) Yorkshire's receipt of
special and ordinary dividends; (b) the receipt by each Yorkshire residential
customer of a one-time discount pursuant to an agreement among the
shareholders of NGG; and
 
                                      39
<PAGE>
 
(c) Yorkshire's receipt of an in-kind dividend of approximately 9.2% of the
shares of PSB Holdings Limited ("PSB"), the holding company of First Hydro
Limited, which shares were subsequently converted to cash upon PSB's
liquidation.
 
SIGNIFICANT FACTORS AND KNOWN TRENDS
 
 Competition and Industry Challenges
 
  On April 1, 1995 and 1996, certain reductions in allowed distribution
revenues were made by the Regulator. Yorkshire's allowed distribution revenues
were impacted by a 14% below inflation reduction and a 13% below inflation
reduction on April 1, 1995 and 1996, respectively, following reviews by the
Regulator. On April 1, 1997 and April 1, 1998, Yorkshire's allowed
distribution revenues were decreased by an additional 3% below inflation
reduction, and there will be a further 3% below inflation reduction on April
1, 1999.
 
  The potential exists for additional distribution price reductions based upon
further review by the Regulator. The next scheduled Distribution Price Control
Formula review will be in 2000. Future cost efficiency initiatives may not
result in sufficient savings to offset price reductions. Price reductions are
mitigated by the inclusion of the UK Retail Price Index in the determination
of the Distribution Price Control Formula. Because the maximum average price
in any year is based in part on the maximum average price in the preceding
year, a price reduction in any given year has an ongoing effect on the maximum
average price for all subsequent years. See "The Electric Utility Industry in
Great Britain--Distribution of Electricity--Price Control".
 
  Yorkshire currently has an exclusive right to supply electricity to its
Franchise Supply Customers. Competition in supply to such customers was
scheduled to be phased in over a six month period commencing on April 1, 1998.
In October 1997, the Regulator published proposals for new transitional supply
price restraints to apply from April 1, 1998 to residential and small business
customers for an initial period of two years and until an adequate level of
competition is established. Yorkshire subsequently indicated its acceptance of
such proposals. The proposals (when taken together with the reduction in the
Fossil Fuel Levy, which became effective on April 1, 1998) resulted in the
implementation of small reductions, effective April 1, 1998, in the tariffs
for Yorkshire's residential and small business customers in its Franchise Area
compared to the corresponding tariffs in effect in August 1997. The proposals
also require an additional 3% below inflation reduction effective April 1,
1999. See "The Electric Utility Industry in Great Britain--Supply of
Electricity--Price Regulation".
 
  Following an announcement in January 1998 by the Regulator, competition in
supply to Franchise Supply Customers has been delayed until September 1998.
Assuming that such competition starts as currently scheduled in September 1998
for Franchise Supply Customers, Yorkshire Group presently estimates that costs
totalling (Pounds)75 million will have been incurred for re-engineering and
information technology work. Of such amount, approximately (Pounds)19 million
was expensed in Fiscal Year 1997. The Regulator has made proposals (which have
been accepted by Yorkshire) to allow Yorkshire recovery of (Pounds)23 million
over a five year period ending March 31, 2003. A further (Pounds)7 million is
expected to be recovered through Pool cost recovery and other national
mechanisms and (Pounds)8 million is expected to be capitalized as such amount
is expected to provide future benefits to the supply business. As a result of
the above, the residual amount of approximately (Pounds)18 million, which will
not be recovered or capitalized, will be expensed in Fiscal Years 1998 and
1999 as incurred.
 
  The Regulator has also made proposals (which have been accepted by
Yorkshire) to provide an annual allowance of (Pounds)3 million for the period
1998 through 2000 to cover operating costs. The allowance will be reviewed at
the time of the Distribution Price Formula Control review in 2000.
 
  The October 1997 proposals therefore will allow Yorkshire to recover up to
50% of its forecasted set-up and operating costs over a five year period. The
shortfall could be higher if: (i) operating costs are higher than anticipated
(e.g., there is a higher level of customer activity); (ii) recovery of
operating costs is disallowed or reduced when the Distribution Price Control
Formula is reviewed for the period beginning April 1, 2000; or (iii) the
integrated national systems do not work as contemplated or require substantial
redevelopment.
 
                                      40
<PAGE>
 
  The Regulator's proposals also provided that a REC should be penalized: (i)
where it starts to open its market more than three months after the market
opening by the first REC; (ii) where it opens successive tranches of its
market more than three months after the opening of the corresponding tranche
by the first REC; and (iii) where the market opening of the first REC has been
delayed beyond April 1, 1998. The penalties will be calculated at 1% of the
operating revenues of the supply business for Franchise Supply Customers per
month of delay, weighted by the proportion of customers affected and applied
as a reduction in allowed distribution business income. If Yorkshire does not
open its market for Franchise Supply Customers to competition until after
April 1, 1999, it would incur a penalty of approximately (Pounds)6 million. It
is now apparent that some penalty will be incurred due to the delay in the
opening of the competitive market for Franchise Supply Customers until
September 1998. Yorkshire Group expects that Yorkshire will be prepared to
open its Franchise Area to such competition in September 1998.
 
 Factors Affecting Revenues
 
  Two principal factors determine the amount of revenues produced by the
distribution business: the unit price of electricity distributed (which is
controlled by the Distribution Price Control Formula) and the number of
electricity units distributed (which depends upon customer demands as
influenced in part by economic activity and weather conditions).
 
  Two principal factors determine the amount of revenues produced by the
supply business: the unit price of the electricity supplied (which, in the
case of the Franchise Supply Customers, is controlled by the Supply Price
Control Formula) and the number of electricity units supplied. Yorkshire is
currently expected to have the exclusive right to supply all Franchise Supply
Customers in its Franchise Area until September 1998.
 
 UK Tax Law Changes
 
  On July 2, 1997, the UK government enacted certain changes in tax law,
including a one-time windfall tax on privatized industries and a reduction in
rates of corporation tax on income from 33% to 31%. The windfall tax on
Yorkshire is (Pounds)134 million and will not be deductible for UK corporation
tax purposes. The windfall tax has been recorded as an extraordinary charge in
the nine month period ended December 31, 1997. The tax is payable in two equal
installments on December 1, 1997 and 1998. During the nine month period ended
December 31, 1997, Yorkshire Group estimated the impact of the reduction in
corporation tax rates, which resulted in a one-time reduction in deferred
income tax liabilities and a corresponding reduction in income tax expense of
approximately (Pounds)12 million.
 
 Business Restructuring
 
  In December 1997, Yorkshire announced a planned business restructuring
intended to enable it to meet increased competition and react to potential
regulatory developments in the energy markets in the UK. The restructuring
will result in the distribution and supply businesses becoming self-sufficient
businesses. As part of the restructuring, an alternative ownership structure
will be pursued for the generation business. Yorkshire currently contemplates
transferring such assets to an entity or entities other than Yorkshire Group
or its subsidiaries. It is expected that proceeds from the transfer of these
assets will be used to reduce debt of Yorkshire Group. See "Certain
Relationships and Related Transactions".
 
  Total assets less current liabilities employed by the generation business at
December 31, 1997 were (Pounds)168 million. Operating income attributable to
the generation business in the nine months ended December 31, 1997 was
(Pounds)12 million.
 
  As a result of this restructuring, approximately 160 positions will be
eliminated. A provision of approximately (Pounds)10 million was recorded in
the nine month period ended December 31, 1997 to reflect the cost of these
workforce reductions.

 Investment in Ionica
 
  Yorkshire has an equity investment in Ionica, a telecommunications company.
The holding in Ionica was initially included in Yorkshire Group's consolidated
balance sheet at its fair value at acquisition on April 1, 1997 of (Pounds)54
million, plus a subsequent additional investment of (Pounds)1 million.
Following an announcement in November 1997 by Ionica of a temporary delay in
its roll out program due to problems in upgrading software, the fair value of
Yorkshire Group's investment in Ionica decreased to (Pounds)30 million at
December 31, 1997. At April 30, 1998, the fair value of Yorkshire Group's
investment in Ionica was valued at (Pounds)19 million ($31 million). This
reduction below the recorded book value has not been included as a charge
against earnings in Yorkshire Group's consolidated financial statements as the
diminution in value is not considered permanent.
 
 Derivative Financial Instruments and Interest Rates
 
  Derivative financial instruments are used by Yorkshire on a limited basis
and are utilized only to mitigate business risks and not for speculative
purposes.
 
  Yorkshire Group maintains its cash balances in pounds sterling. However,
Yorkshire Group's obligations related to the issuance of the Senior Notes will
be payable in US dollars. Yorkshire Group is not currently engaged in any
hedging of currency risks, although it expects to utilize derivative financial
instruments to hedge a portion of the currency risks associated with this
exposure.
 
  Changes in interest rates have not had a significant impact on Yorkshire in
the last three years. However, Yorkshire has entered into debt facilities
which bear interest at variable rates. As part of its risk management policy
and to mitigate the effects of interest rate changes, Yorkshire Group enters
into interest rate swap agreements under which counterparties have agreed to
pay amounts to Yorkshire Group equal to variable interest obligations in
consideration of amounts payable by Yorkshire Group equivalent to fixed rates
of interest. If the counterparty to the interest rate swap was to default on
contractual payments, Yorkshire Group could be exposed to increased costs
related to replacing the original agreement. See Note 7, "Financial
Instruments", to Yorkshire's consolidated financial statements for the three
years ended March 31, 1997 and Note 6, "Interest Rate Swaps", to Yorkshire
Group's condensed consolidated financial statements for the nine months ended
December 31, 1997 included elsewhere in this Prospectus for additional
information on such agreements.
 
 Environmental Factors
 
  Yorkshire's businesses are subject to numerous regulatory requirements with
respect to the protection of the environment. The principal laws which have
environmental implications for Yorkshire are the Electricity Act, the
Environmental Protection Act 1990, the New Road and Street Works Act 1991 and
the Environment Act 1995. Yorkshire believes that it has taken, and intends to
continue taking, measures to comply with the applicable law and government
regulations for the protection of the environment. There are no material legal
or administrative proceedings pending against Yorkshire with respect to any
environmental matter.
 
 Inflation
 
  Inflation neither has had a significant impact on Yorkshire in the last
three years, nor is expected to do so in the foreseeable future. Yorkshire's
revenues from regulated activities are adjusted based on factors which include
an index for inflation in costs of operations.
 
 Year 2000 Issues
 
  Yorkshire Group is currently evaluating its business systems and processes
to determine the extent to which modifications are required to prevent
problems related to the year 2000, and the resources which will be required to
make such modifications. Yorkshire Group has established a dedicated team to
coordinate and control all date conformity work within a structured program
framework. Yorkshire Group estimates that the costs associated with year 2000
modifications will be approximately (Pounds)26 million, of which (Pounds)17
million will be expensed as incurred, and (Pounds)9 million will be
capitalized.

RESULTS OF OPERATIONS
 
  Nine Months Ended December 31, 1997 for the Successor Company Compared with
Nine Months Ended December 31, 1996 for the Predecessor Company
 
 Earnings
 
  Income from operations increased by (Pounds)3 million (3%) from (Pounds)120
million for the nine months ended December 31, 1996 to (Pounds)123 million for
the nine months ended December 31, 1997. This increase was principally due to
a decrease in net periodic pension costs of (Pounds)9 million, due to an
increase in the market value of the pension fund, other cost savings, and a
(Pounds)24 million charge in the nine months ended December 31, 1996 relating
to the replacement of billing and debt collection systems partially offset by
a provision of (Pounds)10 million for restructuring costs, amortization of
goodwill of (Pounds)18 million and additional depreciation of (Pounds)5
million arising from the revaluation of distribution network assets in
connection with the Acquisition.
 
  Income from operations by segments for the nine months ended December 31,
1997 was (Pounds)89 million, (Pounds)14 million and (Pounds)20 million for the
distribution, supply and other segments, respectively. Income from those
segments in the nine months ended December 31, 1996 was (Pounds)99 million,
(Pounds)1 million and (Pounds)20 million, respectively.
 
  Net interest expense rose from (Pounds)20 million for the nine months ended
December 31, 1996 to (Pounds)78 million for the nine months ended December 31,
1997 principally as a result of the financing costs associated with the
increased amount of debt incurred in connection with the Acquisition.
 
  Net income decreased by (Pounds)169 million, from (Pounds)77 million in the
nine months ended December 31, 1996 due to a loss of (Pounds)92 million in the
nine months ended December 31, 1997. In addition to the variances discussed
above, the net loss for the nine months ended December 31, 1997 includes an
extraordinary charge of (Pounds)134 million for the windfall tax enacted by
the UK government in July 1997. The windfall tax is not deductible for UK
corporation tax purposes. Net income before this extraordinary charge for the
nine months ended December 31, 1997 was (Pounds)42 million.
 
 Revenues
 
  Operating revenues decreased by (Pounds)65 million (7%) from (Pounds)974
million in the nine months ended December 31, 1996 to (Pounds)909 million
during the nine months ended December 31, 1997 as follows:

</TABLE>
 
  Revenues from the distribution business decreased by (Pounds)1 million from
(Pounds)225 million for the nine months ended December 31, 1996 to (Pounds)224
million for the nine months ended December 31, 1997 due to a decrease in the
maximum allowable average price of units distributed as a result of the
application of the revised Distribution Price Control Formula. Units
distributed increased by 1% in the nine months ended December 31, 1997
partially offsetting such decrease.
 
  Franchise Supply Customers, who are generally residential and small
commercial customers, comprised 51% of total sales volume for the nine months
ended December 31, 1997. The volume of unit sales of electricity
 
                                      43
<PAGE>
 
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, who are typically
large commercial and industrial businesses, constituted 49% of total sales
volume for the nine months ended December 31, 1997. Sales to Non-Franchise
Supply Customers are determined primarily by the success of the supply
business in contracting to supply electricity to customers who are located
both inside and outside the Franchise Area.
 
  During the nine months ended December 31, 1997, the number of electricity
units supplied decreased by 4% and total revenues produced by the supply
business decreased by (Pounds)69 million (8%) to (Pounds)799 million from
(Pounds)868 million for the nine months ended December 31, 1996. Revenues
decreased partly due to a reduction of 10% in sales to Non-Franchise Supply
Customers as a result of increased competition and partly due to reduced
purchase of electricity costs, the benefits of which are passed on to
customers.
 
 Cost of Sales
 
  Cost of sales decreased by (Pounds)63 million (9%) from (Pounds)681 million
in the nine months ended December 31, 1996 to (Pounds)618 million in the nine
months ended December 31, 1997. This decrease was due principally to the
reduction in units supplied. Additionally, electricity purchase costs
decreased due primarily to reductions in the Fossil Fuel Levy.
 
 Operating Expenses
 
  Operating expenses decreased by (Pounds)5 million (3%) from (Pounds)173
million in the nine months ended December 31, 1996 to (Pounds)168 million in
the nine months ended December 31, 1997. This decrease was principally due to
a reduction in pension costs of (Pounds)9 million, other cost savings and the
recording of a (Pounds)24 million charge relating to the replacement of
billing and debt collection systems in the nine months ended December 31, 1996
partially offset by a provision of (Pounds)10 million for restructuring and an
increase of (Pounds)23 million relating to increased depreciation and
amortization of goodwill due to the Acquisition.
 
 Net Interest Expense
 
  Net interest expense increased by (Pounds)58 million from (Pounds)20 million
during the nine months ended December 31, 1996 to (Pounds)78 million in the
nine months ended December 31, 1997, principally as a result of the financing
costs associated with the 1997 Credit Facility entered into to finance the
Acquisition.
 
 Income Taxes
 
  Yorkshire Group's effective income tax rate, excluding the windfall tax,
decreased from 34% for the nine months ended December 31, 1996 to 11% for the
nine months ended December 31, 1997. The effective rate in the 1997 period was
affected by the (Pounds)12 million favorable impact of the reduction in the UK
corporation tax rate from 33% to 31% as discussed above, partially offset by
the amortization of goodwill, which is not deductible for UK income tax
purposes.
 
 Windfall Tax
 
  Yorkshire Group recorded a one-time extraordinary charge of (Pounds)134
million during the nine months ended December 31, 1997 for the windfall tax
enacted by the UK government in July 1997. This windfall tax is not deductible
for UK corporation tax purposes.
 
Fiscal Year 1997 Compared with Fiscal Year 1996
 
 Earnings
 
  Income from operations was (Pounds)52 million in Fiscal Year 1997, a
decrease of (Pounds)162 million from (Pounds)214 million in Fiscal Year 1996.
The following items reduced Fiscal Year 1997 income from operations: (i) a
(Pounds)78 million provision for uneconomic gas and electricity contracts,
which resulted in a charge of (Pounds)125 million to the supply
 
                                      44
<PAGE>
 
business offset by an intrabusiness elimination of (Pounds)47 million; (ii) a
(Pounds)50 million charge for information system development costs to prepare
for the opening of the competitive electricity market in 1998 for Franchise
Supply Customers, of which (Pounds)37 million was charged to the supply
business and (Pounds)13 million was charged to the distribution business;
(iii) a (Pounds)26 million decrease in distribution revenues as a consequence
of price reductions imposed by the Regulator; (iv) a (Pounds)8 million charge
incurred for advisers' fees in respect of the Acquisition; and (v) a (Pounds)6
million write-down of the value of non-operational property.
 
  Income (loss) from operations by segments for Fiscal Year 1997 were
(Pounds)127 million, (Pounds)(132) million and (Pounds)10 million for the
distribution, supply and other segments, respectively. Income from operations
from those segments in Fiscal Year 1996 were (Pounds)164 million, (Pounds)30
million and (Pounds)20 million, respectively.
 
  Net income was (Pounds)26 million in Fiscal Year 1997, a decrease of
(Pounds)367 million from (Pounds)393 million in Fiscal Year 1996, principally
due to the NGG Transaction in Fiscal Year 1996 and the charges recorded in
Fiscal Year 1997 discussed above.
 
 Revenues
 
  Operating revenues decreased by (Pounds)100 million (7%) from (Pounds)1,431
million in Fiscal Year 1996 to (Pounds)1,331 million in Fiscal Year 1997 as
follows:

</TABLE>
 
  Revenues from the distribution business decreased by (Pounds)26 million (8%)
from (Pounds)334 million for Fiscal Year 1996 to (Pounds)308 million for
Fiscal Year 1997, principally due to a decrease in the maximum allowable
average price of units distributed as a result of the application of the
revised Distribution Price Control Formula. Units distributed increased by
0.5% in Fiscal Year 1997 partially offsetting such decrease.
 
  During Fiscal Year 1997, the number of electricity units supplied decreased
by 6% while total revenues produced by the supply business decreased by
(Pounds)131 million (10%) to (Pounds)1,178 million from (Pounds)1,309 million
for Fiscal Year 1996. The reduction was partly due to a decrease of 12% in
units supplied to Non-Franchise Supply Customers, which was largely offset by
a corresponding reduction in cost of sale, and partly due to reduced charges
from the distribution business, the benefits of which are passed on to
customers, resulting in lower average unit prices. Franchise Supply Customers
and Non-Franchise Supply Customers each comprised 50% of total sales volume in
Fiscal Year 1997.
 
 Cost of Sales
 
  Cost of sales decreased by (Pounds)81 million (8%) from (Pounds)1,013
million in Fiscal Year 1996 to (Pounds)932 million in Fiscal Year 1997. This
reduction was the result of a decrease in supply business sales volumes and
reduced charges from the distribution business.
 
 Operating Expenses
 
  Operating expenses increased by (Pounds)143 million (70%) from (Pounds)204
million in Fiscal Year 1996 to (Pounds)347 million in Fiscal Year 1997.
Operating costs in Fiscal Year 1997 included: (i) a (Pounds)78 million
provision for uneconomic
 
                                      45
<PAGE>
 
gas and electricity contracts made for the net present value of expected
future payments in excess of anticipated recoverable amounts, reflecting
expectations of market prices for electricity following the opening of the
competitive electricity market in 1998 for Franchise Supply Customers and
future gas prices; (ii) a (Pounds)50 million charge for information system
development costs, including (Pounds)19 million relating to the opening of the
competitive electricity market in 1998 for Franchise Supply Customers and a
(Pounds)31 million charge relating to the replacement of billing and debt
collection systems; (iii) a (Pounds)8 million charge incurred for advisers'
fees in respect of the Acquisition; and (iv) a (Pounds)6 million write-down of
the value of non-operational property.
 
 Other Income
 
  Other income was (Pounds)20 million in Fiscal Year 1997, a decrease of
(Pounds)293 million from (Pounds)313 million in Fiscal Year 1996. Other income
in Fiscal Year 1996 included the NGG Transaction, totalling (Pounds)300
million as described under "--Fiscal Year 1996 Compared with Fiscal Year
1995--Other Income". Following the NGG Transaction, ordinary dividends
received from NGG decreased from (Pounds)21 million in Fiscal Year 1996 to
(Pounds)2 million in Fiscal Year 1997. Other income for Fiscal Year 1997 also
includes the effect of the (Pounds)15 million gain on disposal by Yorkshire of
its share of a joint venture investment.
 
 Net Interest Expense
 
  Net interest expense increased by (Pounds)13 million from (Pounds)20 million
in Fiscal Year 1996 to (Pounds)33 million in Fiscal Year 1997, including a
(Pounds)7 million charge in relation to the termination of interest rate swap
agreements. Increased financing costs arising from the payment of a special
dividend of (Pounds)185 million in January 1996 were partly mitigated by the
effects of asset sales.
 
 Income Taxes
 
  The effective income tax rate of 22% in Fiscal Year 1996 increased to 33%
for Fiscal Year 1997. The effective income tax rate in Fiscal Year 1996 was
reduced principally due to the lower tax rate on gains arising from the NGG
Transaction. See Note 6, "Income Taxes", to Yorkshire's consolidated financial
statements for the three years ended March 31, 1997 included elsewhere in this
Prospectus for additional information.
 
 Fiscal Year 1996 Compared with Fiscal Year 1995
 
  Earnings
 
  Income from operations was (Pounds)214 million in Fiscal Year 1996, a
decrease of (Pounds)1 million from Fiscal Year 1995. Distribution revenues
decreased by (Pounds)28 million, principally due to a reduction in the maximum
allowable average price of units distributed as a result of the application of
the revised Distribution Price Control Formula. This decrease was largely
offset by cost savings.
 
  Income from operations by segments for Fiscal Year 1996 were (Pounds)164
million, (Pounds)30 million, and (Pounds)20 million for the distribution,
supply and other segments, respectively. Income from operations from those
segments in Fiscal Year 1995 were (Pounds)176 million, (Pounds)23 million, and
(Pounds)16 million, respectively.
 
  Other income was (Pounds)313 million in Fiscal Year 1996, an increase of
(Pounds)297 million from (Pounds)16 million in Fiscal Year 1995 due to the NGG
Transaction totalling (Pounds)300 million which are described in detail below.
 
  Income taxes increased by (Pounds)36 million, from (Pounds)78 million in
Fiscal Year 1995 to (Pounds)114 million in Fiscal Year 1996, including taxes
relating to the NGG Transaction.
 
  Net income increased by (Pounds)252 million from (Pounds)141 million in
Fiscal Year 1995 to (Pounds)393 million in Fiscal Year 1996, principally due
to increased other income as a result of the NGG Transaction offset by the
income taxes discussed above.

</TABLE>
 
  Revenues from the distribution business decreased by (Pounds)28 million (8%)
from (Pounds)362 million for Fiscal Year 1995 to (Pounds)334 million for
Fiscal Year 1996, principally due to a decrease in the maximum allowable
average price of units distributed as a result of the application of the
revised Distribution Price Control Formula. A 3% increase in sales volume
partially offset the average price decrease.
 
  Revenues from the supply business decreased by (Pounds)34 million (3%) from
(Pounds)1,343 million in Fiscal Year 1995 to (Pounds)1,309 million in Fiscal
Year 1996 as a result of lower average unit prices, principally due to reduced
charges from the distribution business, the benefits of which are passed on to
customers, and a decrease in units sold of 1%. Franchise Supply Customers
comprised 46% of total sales volume in Fiscal Year 1996 and Non-Franchise
Supply Customers comprised 54%.
 
 Cost of Sales
 
  Cost of sales decreased by (Pounds)12 million (1%) from (Pounds)1,025
million in Fiscal Year 1995 to (Pounds)1,013 million in Fiscal Year 1996 as a
result of the decrease in units sold.
 
 Operating Expenses
 
  Operating expenses decreased by (Pounds)20 million (9%) from (Pounds)224
million in Fiscal Year 1995 to (Pounds)204 million in Fiscal Year 1996 as a
result of cost savings, principally due to a reduction in the number of
employees from 4,567 at the end of Fiscal Year 1995 to 3,907 at the end of
Fiscal Year 1996.
 
 Other Income
 
  Other income increased by (Pounds)297 million from (Pounds)16 million in
Fiscal Year 1995 to (Pounds)313 million in Fiscal Year 1996. During Fiscal
Year 1996, Yorkshire, together with the other 11 RECs in the UK, distributed
the majority of its shares in NGG to its shareholders in connection with the
NGG Transaction. The NGG Transaction had a material impact on Yorkshire's
financial results for that year. The NGG Transaction included the following:
 
    (a) Yorkshire received special dividends totalling (Pounds)118 million.
 
    (b) At April 1, 1995, Yorkshire held 9.2% of the issued share capital of
  NGG, which was recorded on its balance sheet at (Pounds)72 million.
  Additional share capital of NGG, totalling (Pounds)16 million, was
  subscribed for by Yorkshire during Fiscal Year 1996. In December 1995, when
  NGG became a company listed on the London Stock Exchange, Yorkshire
  revalued its interest in NGG to its market value of (Pounds)321 million.
  Also in December 1995, Yorkshire made a distribution in-kind to its
  shareholders of approximately 90% of its interest in NGG. A further 2%,
  approximately, was distributed to Yorkshire's optionholders. The aggregate
  gain arising from these distributions totalled (Pounds)215 million.
 
 
                                      47
<PAGE>
 
    (c) Each Yorkshire residential customer received a one-time discount as
  part of an agreement among the shareholders of NGG, which stipulated that
  each REC would provide such discount. The net cost of such discount was
  (Pounds)85 million.
 
    (d) Yorkshire received an in-kind dividend of approximately 9.2% of the
  shares of PSB, which shares were subsequently converted to cash upon PSB's
  liquidation, resulting in a gain of (Pounds)56 million.
 
    (e) Legal and other expenses relating to these transactions totalled
  (Pounds)4 million.
 
  Other income in Fiscal Year 1995 also included a one-time termination
payment of (Pounds)17 million received from Stockholm Stadshus AB and a one-
time loss of (Pounds)18 million following the disposal of the business and
certain of the assets of Homepower Retail Limited, Yorkshire's retailing joint
venture.
 
 Net Interest Expense
 
  Net interest expense increased by (Pounds)8 million from (Pounds)12 million
in Fiscal Year 1995 to (Pounds)20 million in Fiscal Year 1996, principally as
a result of substantially more long-term debt outstanding during Fiscal Year
1996 than during Fiscal Year 1995 due to the payment of a special dividend of
(Pounds)188 million in January 1995.
 
 Income Taxes
 
  The effective income tax rate decreased from 36% to 22% from Fiscal Year
1995 to Fiscal Year 1996, principally due to a lower effective income tax rate
on the NGG Transaction. See Note 6, "Income Taxes", to Yorkshire's
consolidated financial statements for the three years ended March 31, 1997
included elsewhere in this Prospectus for additional information.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Yorkshire Group's sole investment and only significant asset is the entire
share capital of Yorkshire Holdings, which, in turn, owns the entire share
capital of Yorkshire. Yorkshire Group is therefore dependent upon dividends
from Yorkshire for its cash flow.
 
  At December 31, 1997, in addition to cash flow from Yorkshire's operations
available for distribution indirectly to Yorkshire Group, Yorkshire Group had
(Pounds)300 million available under existing bank facilities, including
(Pounds)50 million under the 1997 Credit Facility, as its primary source of
liquidity.
 
  Yorkshire Group will be required to refinance the 1997 Credit Facility,
which matures on July 30, 1998. For a discussion of the 1997 Credit Facility,
see Note 11, "Acquisition", to Yorkshire Group's consolidated balance sheet as
of April 1, 1997 included elsewhere in this Prospectus. Yorkshire Group
currently expects to refinance the 1997 Credit Facility through a series of
transactions, including the February 1998 issuance of (Pounds)200 million of
the Guaranteed Eurobonds, the February 1998 issuance of (Pounds)396 million of
the Senior Notes, the issuance of (Pounds)168 million of the Trust Securities
offered hereby, the potential issuance of additional senior notes, the
entering into of additional credit facilities, if available and on terms
acceptable to Yorkshire Group, and from the proceeds of the currently
contemplated transfer of Yorkshire Group's generation assets to an entity or
entities other than Yorkshire Group or its subsidiaries. Yorkshire Group is
currently in negotiations with respect to the replacement of the 1997 Credit
Facility.
 
  Yorkshire Group also will be required to fund its ongoing capital
expenditures, fund its debt service (including with respect to the Trust
Securities) and the final windfall tax payment and cover its seasonal working
capital needs. Yorkshire Group expects to fund these ongoing cash requirements
through a combination of available cash flow from Yorkshire's operations and
amounts available under the committed bank facilities of (Pounds)300 million.
 
  The principal sources of funds of the Successor Company during the nine
months ended December 31, 1997 were (Pounds)63 million from operations, which
reflects interest paid of (Pounds)66 million and tax paid of (Pounds)71
million, including the first installment of the windfall tax of (Pounds)67
million. Yorkshire Group raised (Pounds)1,034 million from
 
                                      48
<PAGE>
 
the 1997 Credit Facility and (Pounds)440 million in equity. During this
period, Yorkshire Group utilized (Pounds)1,474 million to acquire Yorkshire,
(Pounds)129 million for capital expenditures and (Pounds)61 million to repay
short-term loans.
 
  The principal sources of funds of Yorkshire during Fiscal Year 1997 were
(Pounds)96 million from operations, which reflects interest paid of (Pounds)42
million and tax paid of (Pounds)30 million. During Fiscal Year 1997, Yorkshire
invested (Pounds)121 million in capital expenditures and long-term investments
and paid dividends of (Pounds)71 million. Proceeds from asset sales totalled
(Pounds)73 million.
 
  The principal sources of funds of Yorkshire during Fiscal Year 1996 were
(Pounds)222 million from operations, which reflects interest paid of
(Pounds)46 million and tax paid of (Pounds)98 million. During Fiscal Year
1996, Yorkshire invested (Pounds)126 million in capital expenditures and long-
term investments and paid dividends of (Pounds)243 million, including a
special dividend of (Pounds)185 million. Proceeds from asset sales, including
PSB, totalled (Pounds)119 million. Yorkshire raised (Pounds)150 million from
the issuance of Eurobonds.
 
  At December 31, 1997, the Successor Company had net current liabilities of
(Pounds)1,099 million, primarily as a result of the initial financing
structure of the Acquisition. To meet short-term cash needs, the Successor
Company had (Pounds)118 million of cash and cash equivalents at December 31,
1997.
 
  Yorkshire'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
Yorkshire'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 reliability. Non-operational capital
expenditures are for assets such as fixtures and equipment. For Fiscal Years
1996 and 1997 capital expenditures, net of customer contributions, were
(Pounds)91 million and (Pounds)126 million, respectively. Yorkshire is
required to file five year projections with the Regulator for gross capital
expenditures related to its regulated distribution network and updates of such
projections annually. The most recent projection was for the five year period
ended March 31, 2000 and was filed in July 1997. This filing indicated
Yorkshire's current projection of approximately (Pounds)575 million in capital
expenditures for the five year period. Approximately (Pounds)180 million has
already been spent in Fiscal Year 1996 and Fiscal Year 1997 related to this
five year projection.
 
  To reduce the impact of interest rate changes, Yorkshire Group has entered
into several interest rate swap agreements with total notional amount of
(Pounds)650 million currently outstanding and with maturity dates ranging from
January 2008 to February 2008. The interest rate swaps are from a LIBOR
variable rate to an average fixed rate of approximately 7.3%. See Note 6,
"Interest Rate Swaps", to Yorkshire Group's condensed consolidated financial
statements for the nine months ended December 31, 1997 included elsewhere in
this Prospectus for further information on such agreements.
 
  Yorkshire Group does not have any foreign currency hedging contracts in
place; however, to the extent that it becomes economically desirable, it may
swap some or all of any US dollar liabilities associated with security
issuances back to pounds sterling to hedge the currency risk associated
therewith.
 
  Demand for electricity in the UK, including the Franchise Area, is seasonal,
with demand being higher in the winter months and lower in the summer months.
Yorkshire bills the majority of 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 50% of the Franchise Supply Customers settle their accounts
using regular payment plans based on prepayment or spreading of the cost of
their annual bill evenly throughout the year. A majority of Yorkshire's supply
revenues are based on a fixed price per unit. The cost of supply to Yorkshire
from the Pool, if not covered by hedging mechanisms, varies throughout the
 
                                      49
<PAGE>
 
year, generally being higher in winter months and lower in summer months.
Yorkshire balances the effect of these influences on its working capital needs
with drawings under its available credit facilities.
 
  Yorkshire's supply business to Non-Franchise Supply Customers generally
involves entering into fixed price contracts to supply electricity to its
customers. The electricity is obtained primarily by purchases from the Pool.
Because the price of electricity purchased from the Pool can be volatile due
to the fact that the price is set every half hour, Yorkshire is exposed to
risk arising from differences between the fixed price at which it sells
electricity and the fluctuating prices at which it purchases electricity
unless it can effectively hedge such exposure. To mitigate its exposure to
volatility, Yorkshire utilizes CFDs and power purchase contracts with major UK
power generators to stabilize the price of electricity. Yorkshire had entered
into CFDs and power purchase contracts for 17,882 GWh of electricity for the
nine months ended December 31, 1997. Yorkshire's electricity sales volumes
were 22,391 GWh and 21,116 GWh for Fiscal Year 1996 and Fiscal Year 1997,
respectively.
 
  Management believes that cash flow from operations, together with its
existing sources of credit and the proceeds from the Offering and the
refinancing of the 1997 Credit Facility, will provide sufficient financial
resources to meet Yorkshire Group's projected capital needs and other
expenditure requirements for the foreseeable future. Following the
Acquisition, Yorkshire agreed to an amendment to its PES License to the effect
that it will use all reasonable endeavours to ensure that it maintains an
investment grade credit rating on its long-term debt.

                                   BUSINESS
 
INTRODUCTION
 
  Yorkshire's principal businesses are the distribution of electricity and the
supply of electricity to approximately two million customers. Yorkshire also
conducts ancillary business activities apart from the distribution and supply
businesses that are not subject to price regulation, such as owning an
interest in an off-shore gas field, supplying gas in the competitive market
and holding interests in power generation. See "--Business Restructuring".
 
DISTRIBUTION BUSINESS
 
  Yorkshire's distribution business consists of the ownership, management and
operation of the electricity distribution network within Yorkshire's Franchise
Area. The primary activity of the distribution business is the receipt of
electricity from the national grid transmission system (the "Grid") and the
distribution of electricity to end users connected to Yorkshire's power lines.
Because Yorkshire's distribution business is substantially a regulated
monopoly, virtually all electricity supplied (whether by Yorkshire's supply
business or by other suppliers) to consumers in the Franchise Area is
transported through its distribution network, thus providing Yorkshire with a
stable distribution volume unaffected by customer choice of supplier. As a
holder of a PES License, Yorkshire is subject to a price cap regulatory
framework providing economic incentives to operate in a cost effective manner
and, to a limited extent, to increase the volume of electricity distributed.
See "The Electric Utility Industry in Great Britain".
 
 Distribution Business Customers, Units Distributed, Revenues and Operating
Profit
 
  Yorkshire's Franchise Area covers approximately 10,000 square km (3,860
square miles) from the Pennine uplands in the west, and the cities of Leeds,
Bradford and Sheffield, to the City of Hull, the ports of the Humber estuary
and the eastern coastline. It encompasses the counties of West Yorkshire, East
Yorkshire and almost all of South Yorkshire, together with parts of North
Yorkshire, Derbyshire, Nottinghamshire, Lincolnshire and Lancashire. The
regional economy is diverse. The traditional heavy industries of iron and
steel, coal mining, textiles and engineering continue to contribute to the
regional economy, but their overall significance has declined, particularly in
the last decade. During this period, other industries, such as chemicals and
food and drink, have expanded, as have service sector activities such as
finance, retailing and leisure. The region is well served by road and rail
networks, has three regional airports, and the ports of the Humber estuary
provide access to European markets.

 Competition in the Distribution Business
 
  Yorkshire has not experienced significant competition in its distribution
business. Yorkshire believes that the cost of providing a duplicate
distribution network connected to the Grid would be prohibitive. To the extent
a customer may invest in its own on-site electric generating plants, however,
such customer would no longer require distribution and related services from
Yorkshire except for standby connection to the Grid. The distribution business
is subject to marginal loss of income from related services, such as metering.
For a discussion of certain recently announced proposals impacting metering,
see "The Electric Utility Industry in Great Britain--Distribution of
Electricity--Price Control".
 
 Strategy for the Distribution Business
 
  Yorkshire's distribution strategy consists of maintaining a reliable and
safe distribution system which meets customer expectations while maximizing
its operating efficiencies and fulfilling its regulatory obligations.
 
  To implement its strategy, Yorkshire is taking a number of steps. Yorkshire
intends to maintain a sufficient level of investment in the distribution
system to ensure its continued reliability and safety. In Fiscal Year 1997,
Yorkshire invested (Pounds)169 million in the distribution system, of which
(Pounds)96 million represented capital improvements in new substations, cables
and overhead lines and (Pounds)73 million represented expenditures related to
the operation, repair and maintenance of the distribution system. Yorkshire is
currently investing in a Distribution Asset Management System ("DAMS") that
centralizes information currently stored in over sixty computerized and paper-
based systems into one integrated computerized system. The centralization of
such information is intended to improve both access to and quality of
information which is vital to the operation of an efficient distribution
system.
 
  Yorkshire is also concentrating on maintaining and improving its responses
to system faults. In Fiscal Year 1997, Yorkshire restored services to 95% of
all customers affected by faults within three hours and on average a
 
                                      52
<PAGE>
 
Yorkshire customer was without power for only 59.7 minutes. Furthermore,
Yorkshire has introduced a new toll-free phone number available for customers
who have lost power. Such direct access is intended to permit Yorkshire to
respond more effectively and rapidly to power loss situations. Finally,
Yorkshire publishes a Quality of Supply Report which details the manner in
which Yorkshire intends to improve both the availability and quality of
electricity supply in its region in order to inform both its customers and
OFFER as to its plans for the period to April 2000.
 
 Distribution Facilities
 
  Electricity is transported across the Grid at 400 kV or 275 kV to 21 grid
supply points within Yorkshire's distribution network, where the National Grid
Company transforms the voltage to 132 kV, 66 kV and 33 kV for entry into
Yorkshire's distribution system.
 
  At March 31, 1997, Yorkshire's distribution system consisted of:

   Percentage underground....................... 92%       50%        28%
</TABLE>
 
  The primary distribution system consists of 21 grid supply points from the
Grid, an additional 68 supply points and 357 primary substations. At March 31,
1997, the installed transformer capacity with a secondary voltage higher than
650 v at these substations was 20,527,000 kVA. Remote control facilities
enable the real time monitoring and operation of most of these larger
substations from one central control room.
 
  Yorkshire's distribution substations amount to 12,849 indoor substations,
2,774 outdoor substations and 16,618 pole mounted substations. At March 31,
1997, the installed transformer capacity with a secondary voltage less than
650 v was 9,251,220 kVA.
 
SUPPLY BUSINESS
 
  Yorkshire's supply business consists of selling electricity to end users,
purchasing such electricity and arranging for its distribution to those end
users. Under its PES License, Yorkshire has an exclusive right to supply
electricity to Franchise Supply Customers. This exclusive right is currently
scheduled to continue until September 1998. The supply business to Non-
Franchise Supply Customers, both inside and outside Yorkshire's Franchise
Area, is open to competition.
 
  The following table sets forth the volume of electricity sold, by Non-
Franchise Supply Customer and Franchise Supply Customer, as well as supply
operating revenues and operating income (loss):

 Competition in the Supply Business
 
  The supply business is currently divided between Franchise Supply Customers
within the Franchise Area, and Non-Franchise Supply Customers, inside and
outside the Franchise Area. The non-franchise threshold was lowered to 100 kW
in April 1994 allowing competition in supply for these customers while
Franchise Supply Customers remained subject to regulation. Competition in
supply to Franchise Supply Customers is currently scheduled to be phased in
over a six-month period commencing in September 1998, at which time the
exclusive right of Yorkshire to supply the Franchise Area will cease. The
Regulator, however, proposed transitional price regulation for smaller
consumption Franchise Supply Customers for an initial period of two years
until an adequate level of competition is established. Yorkshire subsequently
indicated its acceptance of such proposals. The proposals (when taken together
with the reduction in the Fossil Fuel Levy which became effective on April 1,
1998) resulted in the implementation of small reductions, effective April 1,
1998, in the tariffs for Yorkshire's residential and small business customers
in its Franchise Area compared to the corresponding tariffs in effect in
August 1997. The proposals also require an additional 3% below inflation
reduction effective April 1, 1999. See "The Electric Utility Industry in Great
Britain--Industry Structure" and "--Supply of Electricity".
 
 Strategy for the Supply Business
 
  Yorkshire's supply strategy consists of (i) protecting and sustaining
Yorkshire's electricity market position within the Franchise Area, (ii) cross-
selling gas to its existing customer base, (iii) securing market share for gas
and electricity supply outside the Franchise Area to the extent that such
contracts are profitable and (iv) seeking marketing and strategic alliances in
the supply business.
 
  To implement its strategy, Yorkshire is taking a number of steps. Yorkshire
is endeavoring to retain its existing Non-Franchise Supply Customers in the
Franchise Area by purchasing electricity at competitive rates from power
generators in the UK and providing high quality customer service. In doing so,
in Fiscal Year 1997, Yorkshire maintained a significant portion of its
existing business. Yorkshire has also applied this strategy to Non-Franchise
Supply Customers outside of its Franchise Area and to gas customers. For
example, in Fiscal Year 1997, Yorkshire was awarded new contracts with such
entities as East Midlands Airport, Lancashire County Council, South
Staffordshire Water and a number of Ministry of Defense sites. Furthermore, in
addition to marketing gas and electricity under the Yorkshire brand name,
Yorkshire intends to enter into "channel partnerships" with various business
and commercial entities (a "channel partner") whereby Yorkshire markets energy
to customers outside of its Franchise Area under the name of the channel
partner or in the joint name of Yorkshire and the channel partner. Yorkshire
is currently negotiating to establish a "channel partnership" with a chain of
retail appliance stores. Yorkshire expects to maintain this strategy for all
business customers and potential business customers after competition
commences for both gas and electricity and to extend this approach to the
residential market. There is no assurance that Yorkshire will be able to enter
into such "channel partnerships" and, if it does, that they will be
successful.
 
  As discussed under "--Affiliate Businesses and Other Investments--Gas
Sourcing and Supply", Yorkshire has taken significant steps toward developing
its gas supply capabilities. Currently, gas may be sold to residential
customers in selected regional markets that have been opened to competition.
By retaining its existing customer base and, eventually, expanding into new
markets which will be open to competition, Yorkshire intends to be in a
position to offer those customers both electricity and gas. In offering such
flexibility, Yorkshire intends to solidify its relationship with these
customers and provide an established market base for its developing gas supply
business.
 
  In a joint statement issued in January 1998, the Regulator and OFGAS asked
each of the RECs and BG Centrica plc (the former supply business of British
Gas plc) ("Centrica") to give undertakings to stop "dual fuel" offers to
supply gas and electricity. In addition, OFGAS asked the RECs to undertake not
to market gas to residential customers in areas where their respective markets
are not open to competition except where contracts have already been signed.
The regulators also made proposals concerning competition in meter reading.
Following discussions with the regulators, it was announced that the RECs had
agreed only to provide additional dual fuel benefits to customers once their
individual franchise area is opened to electricity competition and that OFGAS
had agreed that RECs' gas supply businesses should be permitted to continue to
compete in the gas
 
                                      54
<PAGE>
 
market both within and outside their franchise areas on the basis that there
are no undue restrictions or distortions in the gas market in those areas. The
RECs also agreed to work with the Regulator and OFGAS to ensure measures to
limit distortion of the meter reading market.
 
AFFILIATE BUSINESSES AND OTHER INVESTMENTS
 
  Yorkshire's ancillary business activities have primarily included, among
other things, gas sourcing and supply and holding interests in power
generation.
 
 Gas Sourcing and Supply
 
  Recognizing the long-term opportunities in the competitive gas supply
market, in April 1994, Yorkshire acquired a 6.97% equity stake in the Armada
off-shore gas field (the "Armada Field") for approximately (Pounds)27.8
million. As of December 31, 1997, the Armada Field, which has a production
life of approximately 15 years, had proven resources of approximately 1.2
trillion cubic feet (84 billion cubic feet net to Yorkshire) of gas and 68
million barrels of oil and oil equivalents (4.8 million barrels net to
Yorkshire). Delivery of such gas from the Armada Field to Yorkshire began, on
schedule, in October 1997. The development costs associated with the Armada
Field have been lower than originally anticipated. As of December 31, 1997,
Yorkshire had invested (Pounds)62 million in the Armada Field.
 
  Yorkshire markets gas to industrial and commercial customers and, with the
gradual removal of the residential franchise of Centrica, has recently started
marketing gas to residential customers. By the end of March 1998, Yorkshire
had entered into contracts for the supply of gas to more than 200,000
residential customers. Gas is sourced from Yorkshire's interest in the Armada
Field and through swing contracts and purchases on the spot markets which are
designed to give Yorkshire a balanced purchase portfolio. Yorkshire utilizes
risk management methods, in relation to gas purchasing and supply, similar to
electricity purchasing and supply, which are designed to maximize its return
consistent with an acceptable level of risk.
 
  The Regulator and OFGAS recently proposed to restrict the ability of the
RECs, including Yorkshire, to provide "dual fuel" offers to supply gas and
electricity to residential customers in areas which are not open to
competition. See "--Supply Business--Strategy for the Supply Business".
 
 Power Generation
 
  Through its wholly-owned subsidiary, Yorkshire Electric Power Limited
("YEPL"), Yorkshire has invested in various power generation projects.
Yorkshire's PES License currently enables it and its affiliates to make
investments of up to 800 MW of electricity generation. Currently, Yorkshire
and its subsidiaries own, or have committed to, investments in 519 MW of power
generation assets. See "--Business Restructuring" for a discussion of the
proposed transfer of Yorkshire's current ownership interests in generation
assets.
 
  The centerpiece of Yorkshire's generation activities is a 272 MW combined
cycle gas turbine ("CCGT") generating station at Brigg in north Lincolnshire
developed and operated by Regional Power Generators Limited ("RPG"). YEPL owns
a 75% interest in RPG with IVO Energy Limited holding the remaining 25%.
Yorkshire holds a power purchase agreement for 100% of the output of the
station.
 
  Yorkshire CoGen Limited ("YCL"), a YEPL subsidiary, constructed and
currently operates combined heat and power ("CHP") plants at St. James's
Hospital, Leeds (4.5 MW), A. H. Marks, a chemical company based in Bradford
(4.5 MW) and Queen's Medical Centre, Nottingham (4.9 MW). YCL is also
constructing a 56 MW CHP plant at the premises of Hays Chemicals, a Cheshire
based company, and is nearing completion of a 50 MW CCGT plant at Thornhill.
YCL also owns and operates 52.6 MW of diesel fired peaking plants. YCL has
submitted an application to the UK's Department of Trade and Industry to
construct a 56 MW CHP plant at the premises of Hickson and Welch Chemicals in
Yorkshire. Further small scale (50 MW) embedded plants (including cogeneration
plants) are also planned. All of the above plants provide an opportunity for
Yorkshire's
 
                                      55
<PAGE>
 
electricity supply business to purchase the power offtake and a partial
strategic hedge in the event that electricity prices rise and reduce profit
margins of Yorkshire's supply business.
 
  In addition, YEPL owns a 50% interest in a company which owns two windfarms
at Ovenden Moor (9.2 MW) and at Royd Moor (6.5 MW). All of the output from
these windfarms is sold to The Non-Fossil Fuel Purchasing Agency under an
agreement which expires on December 31, 1998.
 
  YCL's generation portfolio has concentrated on smaller scale projects which
export less than 50 MW, principally because in doing so YCL is not required to
obtain a generation license and such smaller scale projects are not required
to trade in the Pool. Trading outside the Pool means that the export power has
a higher value and provides YCL with increased operational flexibility.
 
CUSTOMER SERVICE
 
  As part of Yorkshire's commitment to delivering high levels of customer
service, Yorkshire launched its Customer Service Initiative in 1995. Virtually
all of its employees have attended training sessions aimed at developing a
company culture consistent with Yorkshire's corporate mission to be a leader
in the market of electricity distribution and electricity and gas supply,
while consistently providing high levels of customer service. These employees
have been trained in the values and behavior which need to be adopted to
achieve this corporate mission.
 
  Improvements to customer service which have been implemented as a result of
this initiative include the provision of a toll-free service for account
inquiries and fault reporting, as described under "--Distribution Business--
Strategy for Distribution Business", and an increase in the number of bill
payment outlets for the convenience of customers.
 
  Yorkshire continues to seek to improve the service it provides to its
customers and, to do so, continues to train employees further. A customer
service tracking system has been put in place to ensure that directors and
managers of Yorkshire gain regular feedback from customers on the service they
receive.
 
RISK MANAGEMENT
 
  Yorkshire's risk management efforts are primarily focused on the supply
business and intended to hedge the risks associated with the purchase and sale
of electricity resulting from Pool price volatility. Virtually all electricity
generated in England and Wales is sold by generators and bought by suppliers
through the Pool. The most common contracts for supply to Non-Franchise Supply
Customers are for twelve-month terms and contain fixed rates. Yorkshire is
exposed to purchase price risk (the risk associated with fluctuations in the
cost of purchased electricity relative to the price received from the supply
customer) to the extent that it has not hedged such risk. Yorkshire
substantially 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 the risk of Pool price
volatility. Yorkshire employs risk management methods to maximize its return
consistent with an acceptable level of risk.
 
  Until March 31, 1998, regulations governing the franchise supply market
permitted the pass-through to customers of prudent purchase costs which
included the cost of arrangements such as CFDs to hedge against Pool price
volatility. Under the supply price restraint proposals published by the
Regulator in October 1997, and accepted by Yorkshire, effective April 1, 1998,
such purchase costs are no longer automatically passed through to such
customers. CFDs are contracts predominantly between generators and suppliers
which fix the major elements of 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,
Yorkshire expects its supply demand for the calendar year 1998 to be
substantially hedged through various types of agreements, including CFDs.
 
 
                                      56
<PAGE>
 
  Yorkshire's ability to manage its purchase price risk depends, in part, on
the continuing 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.
 
BUSINESS RESTRUCTURING
 
  In December 1997, Yorkshire announced a planned business restructuring
intended to enable it to meet increased competition and react to potential
regulatory developments in the energy markets in the UK. The restructuring
will result in the distribution and supply businesses of Yorkshire becoming
self-sufficient businesses. As part of the restructuring, an alternative
ownership structure will be pursued for the generation business. Yorkshire
currently contemplates transferring such assets to an entity or entities other
than Yorkshire Group or its subsidiaries. It is expected that proceeds from
the transfer of these assets will be used to reduce debt of Yorkshire Group.
See "Certain Relationships and Related Transactions".
 
  Total assets less current liabilities employed by the generation business at
December 31, 1997 were (Pounds)168 million. Operating income attributable to
the generation business in the nine months ended December 31, 1997 was
(Pounds)12 million.
 
  As a result of this restructuring, approximately 160 positions will be
eliminated. A provision of approximately (Pounds)10 million was recorded in
the nine months ended December 31, 1997 to reflect the cost of these work
force reductions.
 
UK ENVIRONMENTAL REGULATION
 
  Yorkshire's businesses are subject to numerous regulatory requirements with
respect to the protection of the environment. The principal laws which have
environmental implications for Yorkshire are the Electricity Act, the
Environmental Protection Act 1990, the New Road and Street Works Act 1991 and
the Environment Act 1995.
 
  The Electricity Act requires Yorkshire to consider the preservation of
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. Environmental assessments are required to be
carried out in certain cases including overhead line constructions at higher
voltages and generating station developments. Yorkshire has produced a
Corporate Environmental Policy Statement and an Electricity Act Schedule 9
Statement which sets out the manner in which it intends to comply with its
environmental obligations.
 
  Possible adverse effects of electro-magnetic fields ("EMFs") from various
sources, including transmission and distribution lines, have been the subject
of a number of studies and increasing public discussion. The current
scientific research is inconclusive as to whether EMFs may cause adverse
health effects. There is the possibility that the passage of legislation and
changing regulatory standards would require measures to mitigate EMFs, with
resulting increases in capital and operational costs. In addition, the
potential exists for public liability with respect to lawsuits brought by
plaintiffs alleging damages caused by EMFs. 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 physiological effects
have been observed. Yorkshire fully complies with these standards.
 
  Yorkshire believes that it has taken, and intends to continue taking,
measures to comply with the applicable law and government regulations for the
protection of the environment. There are no material legal or administrative
proceedings pending against Yorkshire with respect to any environmental
matter. Yorkshire estimates (Pounds)7 million was spent on environmental
compliance in Fiscal Year 1998, approximately half of which was of a capital
nature. This level of expenditures is expected to continue in future Fiscal
Years.
 
UK AND EU COMPETITION LAW
 
  Yorkshire's businesses are subject to the competition rules of both the UK
and the European Community.
 
  The UK Restrictive Trade Practices Act 1976 stipulates that failure to
furnish to the Office of Fair Trading an agreement that is registrable under
such Act renders unenforceable certain restrictions contained in such
 
                                      57
<PAGE>
 
agreement. Briefly stated, the Fair Trading Act 1973 and the Competition Act
1980 both regulate the activities of companies with market power. UK
competition law, particularly the law relating to restrictive agreements, is
in the process of reform and is likely to follow the approach of European
Community law.
 
  The Treaty of Rome contains provisions which prohibit anti-competitive
agreements and practices, including the abuse of a dominant position within
the European Union ("EU") or a substantial part of it. Penalties for violation
of these provisions include fines, third party damages and infringing
contractual provisions being unenforceable.
 
  In January 1993, the UK implemented the EU Utilities Directive on the
procedures to be followed for the award of supply and works contracts by
utility companies, including electricity utilities. This directive was
replaced by EU Directive 93/36, which was implemented by the UK in December
1996 and which covers service contracts as well as supply and work contracts.
Those contracts that exceed the relevant financial thresholds have to be
advertised in the Official Journal of the European Communities. Suppliers and
contractors who believe they have suffered harm from failure to implement the
correct procedure in awarding the contract are able to institute proceedings
in the English High Court. The European Commission also has the power to
intervene prior to the award of a contract. Yorkshire Group believes that
Yorkshire has complied with any obligations it may have under those
regulations but the interpretation and application of those regulations and of
the European Union directives which they implement is not free from doubt and
no assurance can be given that any claim for damages against Yorkshire for
breach of the rules would be unsuccessful.
 
EMPLOYEES
 
  Yorkshire had approximately 4,000 employees (approximately 3,800 full-time
equivalent) at the end of Fiscal Year 1997. Yorkshire Group has no employees
because it is a holding company with no operations. Approximately 62% of
Yorkshire's employees are represented by labor unions. All Yorkshire 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 Yorkshire and the unions
and is terminable with 12 months' notice by either side. Yorkshire believes
that its relations with its employees are favorable. See "--Business
Restructuring" for a discussion of planned staffing reductions.
 
PROPERTY
 
  Yorkshire owns the freehold of its principal offices north of Leeds.
Yorkshire has both network and non-network land and buildings.
 
 Network Land and Buildings
 
  At March 31, 1997, Yorkshire had interests in approximately 15,000 network
properties, comprising principally sub-station sites.
 
 Non-Network Land and Buildings
 
  At March 31, 1997, Yorkshire had freehold and leasehold interests in non-
network properties comprising chiefly offices, depots, warehouses, workshops
and a number of former retail outlets. The net book value of total non-network
land and buildings at March 31, 1997 was (Pounds)52 million.
 
LEGAL PROCEEDINGS
 
  Yorkshire is routinely a party to legal proceedings arising in the ordinary
course of business which are not material, either individually or in the
aggregate. Yorkshire currently is not a party to any material legal
proceedings nor is it aware of any threatened material legal proceedings.
 
 
                                      58
<PAGE>
 
  Litigation is ongoing with respect to another corporation's use of actuarial
surpluses declared in the Electricity Supply Pension Scheme ("ESPS"). The
Pension Ombudsman (a UK arbitrator appointed by statute) has issued a "final
determination" in favor of complaints made by members of the ESPS relating to
another corporation's use of the ESPS surplus to offset such corporation's
additional costs of early payment of pensions as a result of reorganization or
redundancy, together with additional contributions required after a valuation.
Under that determination, the Pension Ombudsman directed such corporation to
pay into ESPS the amount of that use of the surplus plus interest. The Pension
Ombudsman's final determination has been successfully challenged in the
courts. At the same time, the courts also considered other areas of
uncertainty relating to the uses made of actuarial surpluses arising in the
ESPS, including the ability to reduce or suspend standard employer
contributions to reduce such surpluses. The courts ruled that such reductions
were permissible. The final decisions of the courts are subject to appeal. If
any of the decisions are reversed on appeal they may have an adverse effect on
Yorkshire, which has made similar use of its actuarial surplus, but no
assurance can be given as to the extent of that effect.

                 THE ELECTRIC UTILITY INDUSTRY IN GREAT BRITAIN
 
  The information set forth below relating to the electric utility industry in
Great Britain has been derived from publicly available sources.
 
SUMMARY
 
  The following summarizes the general structure of the electric utility
industry in England and Wales as it has developed since the privatization of
the industry in 1990. The electric utility industry in England and Wales is
divided into various functions, with different companies participating in the
respective functions. This is in contrast to the US utility industry, in which
vertically integrated companies generally participate in all functions.

                         actually selling the electricity at retail
                         to the end-user. This regulated monopoly
                         in the distribution business can be
                         distinguished from the efforts to introduce
                         competition in the supply business.

                         will be allowed to buy from any licensed

                         distributed by the local REC.

INDUSTRY STRUCTURE
 
  Great Britain has two separate but connected electricity markets, each with
a different commercial framework. In England and Wales electricity is produced
by generators, the largest of which are National Power plc ("National Power"),
PowerGen plc ("PowerGen") and Nuclear Electric plc, a subsidiary of British
Energy plc ("British Energy"). Electricity is transmitted through the Grid by
NGC and distributed by the twelve RECs in their respective franchise 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 customers with
higher Peak Demand in such REC's franchise area.
 
  In Scotland there are two vertically integrated companies, Scottish Power
plc ("Scottish Power") and Scottish Hydro Electric plc ("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.
 
  The interconnection between the two transmission systems, owned by Scottish
Power and NGC, is capable of transferring electricity between Scotland and
England. There is also an interconnection with France, owned by NGC and
Electricite de France, through which electricity can be transferred between
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 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. See "Business--Risk Management".
 
  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 in
order to introduce competition into the generation and supply of electricity.
At the same time, a licensing regime was introduced for the electricity
industry both in England and Wales as well as in Scotland.
 
  The RECs, which at that time collectively owned NGG, NGC's holding company,
were privatized in December 1990. National Power and PowerGen were partly
privatized in March 1991 (with the balance of the UK government's holdings
being sold to investors in March 1995). Scottish Power and Hydro Electric were
privatized in June 1991 and British Energy was privatized in July 1996. By
December 1995, most of the RECs ownership of NGG had been publicly sold, and
NGG was listed on the London Stock Exchange. Since the summer of 1995, 11 of
the RECs have been acquired by other companies. Yorkshire was indirectly
acquired by Yorkshire Group in April 1997.
 
  In 1990, the vast majority of generating capacity in England and Wales was
owned by three generators. However, since that time competition in generation
has increased as RECs and other new entrant generators have constructed new
plants 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
generating capacity to The Energy Group plc ("Energy Group").
 
  Competition in supply has 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. In April
 
                                      61
<PAGE>
 
1990, electricity users with a Peak Demand in excess of 1 MW became Non-
Franchise Customers of a REC and therefore were allowed to choose their
electricity supplier. In April 1994, the Non-Franchise Customer class was
expanded to include users with a Peak Demand in excess of 100 kW. Currently,
all electricity customers in Great Britain are scheduled to be able to choose
their electricity supplier over a six month phase in the period beginning in
September 1998, according to customers' designated postal codes.
 
DISTRIBUTION OF ELECTRICITY
 
 Accessibility Requirements
 
  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 supplemental and
backup 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 supplemental
and backup supplies of electricity, and in the carrying out of connection
works. Disputes over the terms of offers may be determined by the Regulator.
 
 Price Control
 
  Revenue from the distribution business is controlled by a formula
principally based on P x (1+(RPI-Xd)) where Xd is currently 3% (the
"Distribution Price Control Formula"). P is the previous year's maximum
average price per unit of electricity distributed. Because the maximum average
price in any year is therefore based in part on the maximum average price in
the preceding year, a price reduction in any given year has an ongoing effect
on the maximum average price for all subsequent years. RPI is a measure of
inflation, and equals the percentage change in the UK Retail Price Index
between the six month period of July to December of the two previous years.
Because RPI is based on a weighted average of the prices of goods and services
purchased by a typical household, which bear little resemblance to the inputs
contributing to Yorkshire's business costs, the RPI calculation may not
accurately reflect the price changes affecting Yorkshire. 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 current
Distribution Price Control Formula permits RECs to partially retain additional
revenues due to increased distributions of units and allows for a pound for
pound increase in operating profit for efficient operations and reduction of
expenses within a review period. However, during the next Distribution Price
Control Formula review, the Regulator may reduce any such increase in
operating profit to the extent he determines it not to be a function of
efficiency savings or, if genuine efficiency savings have been made, he
determines that customers should benefit through lower prices in the future.
 
  Upon privatization, the Regulator set different Xd factors for each of the
RECs to permit annual price increases by the RECs of between 0% and 2.5% (1.3%
for Yorkshire) greater than RPI for the five year period ending on March 31,
1995. Following a scheduled distribution price review by the Regulator of all
twelve RECs in August 1994, the Regulator required an overall real reduction
in regulated distribution prices for Fiscal Year 1996 of between 11% and 17%
(14% for Yorkshire) from the previous year, and set the Xd factor for the
subsequent four year period ending on March 31, 2000 to subtract 2% from RPI
in each such year. Also in connection with the August 1994 distribution price
review, the Regulator, (i) halved from 100% to 50% the extent to which
distribution revenues would be allowed to vary with the number of units of
electricity distributed and (ii) determined numbers of Franchise Area
customers based on REC forecasts for each year through and including Fiscal
Year 2000, allowing distribution revenues to vary by 50% of the predetermined
annual change in such forecast numbers. 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 light of
information concerning the financial position of the RECs that emerged during
the unsuccessful bid by Trafalgar House plc for Northern Electric plc (one of
the
 
                                      62
<PAGE>
 
RECs) and representations by Consumers' Committees and others, the Regulator
conducted an unscheduled distribution price review of all twelve RECs in July
1995. As a result of this unscheduled review, the Regulator revised regulated
distribution prices for the four year period ending on March 31, 2000,
requiring an overall real reduction in regulated distribution prices for
Fiscal Year 1997 of between 10% and 13% (13% for Yorkshire) from the previous
year, and resetting the Xd factor for the remaining three year period ending
on March 31, 2000 to subtract 3% from RPI in each such year.
 
  The Distribution Price Control Formula is expected to be further reviewed
with effect from April 1, 2000. Following the review, the Regulator will make
a proposal for a revised formula to apply from that date. If a REC does not
agree with the proposal the Regulator may refer the proposal to the MMC and,
following the publication of the report of the MMC, the Regulator may make
appropriate modifications to the REC's PES License.
 
  In setting the distribution charges each year, each REC must project the
permitted maximum average charge per unit to be distributed in that year. The
projection will have to take account of forecasts of units distributed,
distribution line losses, the actual change in RPI and NGC exit charges.
Failure to forecast accurately may result in overcharging or undercharging,
which is taken into account in the following year through a correction factor
in the Distribution 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.
 
  In certain instances, however, overcharging or undercharging by a REC above
specific percentage thresholds may result in adjustments by the Regulator. 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, with respect to 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, with respect to 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.
 
  Since April 1995, the Distribution Price Control Formula has been notionally
divided into metering and non-metering components, with the metering component
equal to about 10% of each REC's allowed revenue. However, the Regulator
indicated when making these proposals that there should be no presumption that
this sum would be assigned to a metering business.
 
  Operations related to the metering of network connections to non half-hourly
metered customers (generally residential and other small customers) are
subject to the metering component of the Distribution Price Control Formula.
Such price controls are scheduled to be disapplied from April 1, 2000, at
which time competitive market pricing is scheduled to be introduced. In a
joint statement issued in January 1998, the Regulator and OFGAS made proposals
concerning competition in meter reading. See "Business--Supply Business--
Strategy for the Supply Business". Competitive market pricing already exists
for operations related to the metering of network connections to half-hourly
metered customers.
 
  Connection charges are levied when a customer first connects to a REC's
distribution system or makes a material change in electricity supply
requirements. These charges are excluded from the Distribution Price Control
Formula. In the August 1994 distribution review, the Regulator introduced the
concept of competition in providing connections to new customers and limited
the extent to which, and the circumstances in which, customers wishing to be
connected would be required to pay for the costs of reinforcement of the
distribution system.

 Data Management Services
 
  Beginning in September 1998, the electricity supply market for Franchise
Supply Customers is currently scheduled to be opened to competition and
customers will be able to select the supplier of their choice. Significant
additional costs have been, and will be, incurred by the distribution business
to develop new systems to facilitate competition. The new services, termed
"data management services" include meter operation, data retrieval, processing
and aggregation, meter point administration and distribution use of system
billing.
 
  Assuming that competition in supply starts as currently scheduled in
September 1998 for Franchise Supply Customers, Yorkshire Group presently
estimates that costs totalling (Pounds)75 million will have been incurred for
re-engineering and information technology work. Of such amount, approximately
(Pounds)19 million was expensed in Fiscal Year 1997. The Regulator has made
proposals (which have been accepted by Yorkshire) to allow Yorkshire recovery
of (Pounds)23 million over a five year period ending March 31, 2003. A further
(Pounds)7 million is expected to be recovered through Pool cost recovery and
other national mechanisms and (Pounds)8 million is expected to be capitalized
as such amount is expected to provide future benefits to the supply business.
As a result of the above, the residual amount of approximately (Pounds)18
million, which will not be recovered or capitalized, will be expensed in
Fiscal Years 1998 and 1999 as incurred.
 
  The Regulator has also made proposals (which have been accepted by
Yorkshire) to provide an annual allowance of (Pounds)3 million for the period
1998 through 2000 to cover operating costs. This allowance will be reviewed at
the time of the Distribution Price Control Formula Review in 2000.
 
  Such proposals therefore will allow Yorkshire to recover up to 50% of its
forecasted set-up and operating costs over a five year period. The shortfall
could be higher if: (i) operating costs are higher than anticipated (e.g.,
there is a higher level of customer activity); (ii) recovery of operating
costs is disallowed or reduced when the Distribution Price Control Formula is
reviewed for the period beginning April 1, 2000; or (iii) the integrated
national systems do not work as contemplated or require substantial
redevelopment.
 
SUPPLY OF ELECTRICITY
 
 Licensed Suppliers
 
  Subject to minor exceptions, all electricity customers in Great Britain must
be supplied by a licensed supplier. Licensed suppliers purchase electricity
and make open access 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, also known as PESs, and second-tier suppliers. PESs include
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 (including
RECs supplying outside their respective franchise areas) and a number of
independent second-tier suppliers.
 
  At present, a Franchise Supply Customer can only buy electricity from the
REC authorized to supply the relevant franchise area. Franchise Supply
Customers typically include residential and small commercial and industrial
customers. Non-Franchise Supply Customers are not limited to buying
electricity from the local REC and can choose to buy from a second-tier
supplier. Such customers are typically larger commercial and industrial
electricity users. Second-tier suppliers compete with one another and with the
local REC to supply customers in this competitive (or "non-franchise") sector
of the market.
 
 Price Regulation
 
 The supply of electricity to Franchise Supply Customers currently remains
subject to price control. The maximum average charge per unit of electricity
supplied (in pence per kilowatt hour) was controlled by a formula principally
based upon (P X (1 + (RPI-Xs)) + Y) (the "Supply Price Control Formula") where
Xs was
 
                                      64
<PAGE>
 
2%. 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 factor was set at 2% for all the RECs. This
applied until March 31, 1998. P was the previous year's maximum average price
per unit of electricity supplied (in pence per kilowatt hour) that relates to
the REC supply business's own costs and margin. RPI was a measure of
inflation, equaling the percentage change in the UK Retail Price Index between
the six month period of July to December of the two previous years. Because
RPI is based on a weighted average of the prices of goods and services
purchased by a typical household, which bear little resemblance to the inputs
contributing to Yorkshire's business costs, the RPI calculation may not
accurately reflect the price changes affecting Yorkshire. The Y factor was a
pass-through of certain costs which are either largely outside the management
control of the REC or have been regulated elsewhere. The Y factor thus covered
the REC's electricity purchase costs, including both direct Pool purchase
costs and costs of hedging, transmission charges made by NGC, REC distribution
charges 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. The Supply Price Control Formula
was therefore designed to focus downward pressure on costs and working
capital, which are viewed as being within suppliers' direct control.
 
  As with the Distribution Price Control Formula, there was a correction
factor in the Supply Price Control Formula in the event of overcharging or
undercharging. If a REC had overcharged in the previous year, the maximum
average charge per unit supplied was reduced by an amount to reflect the
excess income received, to which was added interest. In the event of
undercharging, the Supply Price Control Formula allowed the licensee to
recover the shortfall in income plus interest.
 
  Under the current licensing regime, over a six-month period currently
scheduled to commence in September 1998 all customers, including those who are
currently Franchise Supply Customers, will be permitted to choose their
electricity supplier. The Regulator indicated in his supply price restraint
proposals published in October 1997, which proposals Yorkshire accepted, that
price regulation for supply to all residential and smaller business customers
within Yorkshire's former Franchise Area, whose annual consumption is under
12,000 kWh, would be extended beyond March 31, 1998 until an adequate level of
competition is established, and, at least, until March 31, 2000. The Regulator
has indicated that the nature and extent of possible restraints after that
date will be reviewed in the light of experience and prospects and that such
review would take place concurrently with the ongoing review of the
Distribution Price Control Formula.
 
  The license modifications that have been implemented to effect the new
controls take the form of a series of price caps on the tariffs applicable to
residential and small business customers. The new controls (when taken
together with the reduction in the Fossil Fuel Levy which became effective on
April 1, 1998) have resulted in the implementation of small reductions,
effective April 1, 1998, in the tariffs for Yorkshire's residential and small
business customers compared to the corresponding tariffs in effect in August
1997. See "Fossil Fuel Levy". The new controls also require an additional 3%
below inflation reduction effective April 1, 1999. The license modifications
also discontinued the automatic pass-through of costs currently passed through
to residential and small business customers, consisting primarily of purchased
power costs.
 
  In addition, the license modifications provide for an allowable charge to
cover the additional cost of providing data management services that will be
required to be provided by each REC. For a discussion of the costs associated
with these data management services, see"--Distribution of Electricity--Data
Management Services". The duration and level of the allowances for operating
costs are likely to be reviewed at the time of the next Distribution Price
Control Formula review. The license modifications also provide for restraints
on pre-payment meter charges.
 
  Further, the license modifications stipulated that a REC should be
penalized: (i) where it starts to open its market more than three months after
the market opening by the first REC; (ii) where it opens successive tranches
of its market more than three months after the opening of the corresponding
tranche by the first REC; and (iii) where the market opening of the first REC
has been delayed beyond April 1998. The penalties will be calculated
 
                                      65
<PAGE>
 
at 1% of the operating revenues of the supply business for Franchise Supply
Customers per month of delay, weighted by the proportion of customers affected
and applied as a reduction is allowed for distribution business income. If
Yorkshire does not open its market to competition until after April 1999, it
would incur a penalty of approximately (Pounds)6 million. It is now apparent
that some penalty will be incurred due to the delay in the opening of the
competitive market for Franchise Supply Customers until September 1998.
Yorkshire Group expects that Yorkshire will be prepared to open its Franchise
Area to such competition in September 1998.
 
THE POOL
 
  The Pool was established in April 1990 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. Each day, generators inform NGC of the
amount of electricity which each of their generating units will be able to
provide the next day and the price at which they are willing to operate each
such unit. NGC uses this information to construct a "merit order" which ranks
each generating unit in order of increasing price. NGC then schedules the
stations to operate according to such merit order, calling into service the
least expensive generating units first and continuing to call generating units
into service until enough are operating to meet the demand of all suppliers.
Factors which may constrain NGC's ability to order stations into operation in
strict observance of the merit order include transmission system constraints
and the inflexibility of some generating units. 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.
 
  The UK government recently invited the Regulator to review these electricity
wholesale trading arrangements, trading arrangements outside the Pool and
price setting mechanisms. The review was launched in January 1998 with an
announcement that the Regulator and an independent panel had been asked to
report to the Energy Minister by July 1998.
 
FOSSIL FUEL LEVY
 
  All the RECs are obligated 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 rate of the Fossil Fuel Levy annually.
The current Fossil Fuel Levy is 0.9% of the value of sales of electricity made
in England and Wales and 0.8% of the value of sales of electricity made in
Scotland.
 
REGULATION UNDER THE ELECTRICITY ACT
 
 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
 
                                      66
<PAGE>
 
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 he was reappointed in 1994
for a further five year term ending on August 31, 1999. Professor Littlechild
holds the formal title of Director General of Electricity Supply and is head
of OFFER.
 
  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, in case of non-acceptance of such proposals by
licensees, 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 round; 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 term "supply" as used in the context of the Electricity Act and
the PES License covers both distribution and supply activities.
 
  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
ensure that all reasonable demands for electricity are satisfied, secure that
license holders are able to finance their licensed activities and 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 and maintenance 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
are required 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 are required to
take into account in particular the interests of those who are disabled or of
pensionable age.
 
  On June 30, 1997, the UK government announced its intention to conduct a
comprehensive review of the regulatory framework governing the electricity
distribution and supply businesses in England and Wales, as well as the
regulatory framework applicable to other privatized utilities. The review
culminated in the March Green Paper which sets forth a number of proposals of
the UK Government designed to reexamine utility regulation in the UK. Among
the main proposals contained within the March Green Paper are the retention of
"RPI-X" as the fundamental basis for price regulation; increased transparency
and consistency of regulation; the merger of OFFER and OFGAS; the separate
licensing of the distribution and supply businesses of the PESs; amendment of
the statutory duties of utility regulators to provide a new primary duty to
exercise their functions in the manner best calculated to protect the
interests of the consumers in the short and long term, wherever possible
through promoting competition; and adopting price regulation to distinguish
between income earned through companies' own efforts and income which results
from other factors. Some of these proposals would require primary legislation.
Responses to the March Green Paper by interested parties have been requested
by May 31, 1998. See "Risk Factors--Factors Relating to Yorkshire's Business--
Governmental Review of Utility Regulation".
 
                                      67
<PAGE>
 
  In October 1997, the UK government invited the Regulator to consider
parameters for a review of electricity trading arrangements. Such a review
would focus on the wholesale electricity market in England and Wales and would
likely cover existing trading within the Pool, trading arrangements outside
the Pool and price setting mechanisms. The impact on, and possible need for
change to, the framework of regulatory controls could also be considered,
including Pool governance, regulation of and access to the Grid, licenses, the
Electricity Act and the implications of European Union law. A review of
certain of these issues was launched in January 1998 with an announcement that
the Regulator and an independent panel had been asked to report to the Energy
Minister by July 1998.
 
  In December 1997, the UK government announced a review of energy sources for
power generation, including fuel diversity, sustainable development and the
role of coal. Representations of interested parties were to be submitted by
mid-February 1998. While the review is underway, the Secretary of State has
deferred decisions on most outstanding or new applications for the
construction of generating stations. An Energy Select Committee Report on the
Coal Industry issued in April 1998 recommended that such deferral, as it
relates to the construction of gas fired generating stations, be lifted as
soon as possible. The Trade and Industry Select Committee is also undertaking
an inquiry into a number of aspects of UK energy policy.
 
CONSUMERS' COMMITTEE
 
  The Regulator is required under the Electricity Act to establish a
consumers' committee for the franchise area of each PES License holder (or, if
the Secretary of State so determines, for the franchise areas of two or more
such suppliers). Each committee comprises a chairman appointed by the
Regulator after consultation with the Secretary of State and between 10 and 20
other members appointed by the Regulator after consultation with the committee
chairman. The duties of each committee are to make representations to, and
consult with, their allocated PES License holders about matters affecting the
interests of customers or potential customers of such supplier(s), to review
matters affecting the interests of electricity consumers in such committee's
area, and to advise the Regulator on any other matter which warrants
discussion or which is referred to them by the Regulator.
 
LICENSES
 
 Generation Licenses
 
  Unless covered by an exemption, all electricity generators engaging in the
construction, expansion or operation of a power station in Great Britain are
required to have a generation license. There are currently 51 generation
license holders, including RPG, in Great Britain. Although generation is not
subject to price control, generators are not permitted to discriminate between
customers or cross subsidize their licensed activities. The conditions
attached to a generation license in England and Wales require the holder,
among other things, to comply with the Grid Code, to comply with any REC's
distribution code to the extent applicable, to be a member of the Pool and to
submit relevant generating sets for central dispatch. The conditions attached
to a generation license in Scotland require the holder, among other things, to
comply with the Scottish 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 the license holder is not in compliance with an enforcement order.
 
 PES Licenses
 
  Each of the RECs, Scottish Power and Scottish 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 and the PES
License prohibits cross subsidy between the various regulated businesses. As
described above, PESs are subject to separate price controls on the amounts
they may charge for the use of their distribution system by all customers in
their Franchise Area and for the supply of electricity to Franchise Supply
Customers. The PES Licenses also require the licensee to procure electricity
at the best price reasonably obtainable having regard to the sources
available.
 
                                      68
<PAGE>
 
  As part of his continued monitoring of the electric utility industry, the
Regulator published on August 15, 1996 comparative information relating to the
RECs' economic purchasing performance. The publication entitled "Yardstick of
Electricity Purchase Costs", compared in yardstick value terms, the generation
costs which RECs passed through to Franchise Supply Customers in Fiscal Years
1995 and 1996 under the Supply Price Control Formula. The Regulator has
reviewed the supply price controls applicable to PES License holders and
published in October 1997 proposals for new controls to take effect on April
1, 1998. He issued a consultation paper on this matter on September 5, 1996
entitled "The Competitive Electricity Market from 1998: Price Restraints". He
subsequently issued four further consultation papers in January, May, July and
August, 1997. The October 1997 proposals were for maximum price restraints in
respect of supply to residential and small business customers for a period of
at least two years beginning April 1, 1998, which would eliminate the pass-
through of costs to such customers, consisting primarily of purchased power
costs. Yorkshire accepted these proposals. See "--Supply of Electricity--Price
Regulation".
 
  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 simultaneous maximum
electricity consumption in that REC's franchise area at the time of
privatization. In the case of Yorkshire, the own-generation limit is fixed at
800 MW.
 
  The Regulator has stated that it would be reasonable to consider a REC's
request to increase its own- generation limit on the 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 entering into
additional own-generation contracts in its franchise market. The Regulator
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 Energy Group, 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 of Energy Group
subject to the Regulator and Energy Group agreeing to license modifications as
set out in a consultation paper which he had published in August 1995.
 
  The Regulator has made modifications to 14 PES Licenses in connection with
the introduction of competition for Franchise Supply Customers currently
scheduled to begin in September 1998. These modifications comprise a number of
new obligations to offer services to all competing suppliers. These services
are generally known as data management services, including registration, data
collection and aggregation, meter operation and provision of prepayment meter
infrastructure. The Regulator has issued full modifications to the first-tier
and second-tier licenses to encompass the changes. In response to respective
individual requirements, the PESs are providing collectively a data transfer
service. Preparations are being made to provide these services as part of a
program of work and in October 1997 the Regulator made final proposals for the
recovery of the costs of this program which were accepted by Yorkshire in
November 1997.
 
  The RECs are also contributing to a program of work by the Pool to adopt
settlement arrangements for the competitive market in 1998. It has been agreed
that these costs, subject to a cap above which recovery would be partial, will
be recovered from charges to be made to suppliers by the Pool over a five year
period.
 
 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
"--Supply of Electricity" 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 40 second-tier supply license holders for England and
Wales, including Yorkshire, and 27 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 units and gives NGC
responsibility for the economic purchasing of ancillary services from
generators and suppliers. The transmission
 
                                      69
<PAGE>
 
license requires NGC to offer terms on a nondiscriminatory basis for the
carrying out of works for connection to, and use of, the transmission system.
 
 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. If the Regulator fails to agree to 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.
 
  Following the acquisition of Yorkshire by Yorkshire Group, the Regulator
proposed that Yorkshire's PES License be modified, by agreement, to take into
account the fact that the PES License is now held by a subsidiary company. In
particular, the Regulator proposed that the license be modified to provide
that, with few exceptions, the only business activities which Yorkshire is
permitted to undertake directly are its franchise and second-tier supply
businesses and its distribution business. The license modifications also
require Yorkshire to ensure that it has sufficient management resources and
financial resources and facilities to conduct its supply and distribution
businesses and to comply with its statutory and license obligations. Yorkshire
is required to provide an annual certificate to the Regulator approved by the
Yorkshire Board of Directors and signed by a Director to that effect and in
the interim to notify the Regulator immediately of any changes threatening the
validity of such certificates. Additionally, the license modifications require
Yorkshire to obtain from AEP and NCE legally enforceable undertakings in favor
of Yorkshire that they and their subsidiaries will refrain from any action
which would be likely to cause Yorkshire to breach any of its obligations
under the Electricity Act or the PES License. Further, the consent of the
Regulator is required for Yorkshire 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 Yorkshire or its affiliates or subsidiaries on March 31, 1997) or the
transaction involves any businesses whose aggregate revenues in any financial
year do not exceed 5% of the aggregate turnover of the supply, second-tier
supply and distribution businesses in the previous financial year. The consent
of the Regulator also is required before Yorkshire may transfer assets or make
loans to affiliates or subsidiaries except for certain specified purposes,
including 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. 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 without the
Regulator's express prior consent. Additionally, the license modifications
require Yorkshire to use reasonable efforts to maintain the investment grade
credit ratings of its debt. Finally, because Yorkshire is now owned by
Yorkshire Group, the Regulator required Yorkshire to obtain from AEP and NCE
legally enforceable undertakings to provide information to Yorkshire, as
licensee, in order to comply with requirements of the Regulator. These
modifications to the PES License have been agreed to by Yorkshire and took
effect on December 15, 1997 and the required undertakings were also provided
on December 15, 1997. In February 1998, the Regulator issued, for public
consultation, proposals for further modifications to the licenses of PESs that
have been subject to takeovers. Further proposals are expected to be made by
the Regulator in light of this consultation paper that may result in further
modifications to PES licenses. See "Risk Factors--Factors Relating to
Yorkshire's Business--Regulatory Policies Affecting Yorkshire Group".
 
TERM AND REVOCATION OF LICENSES
 
  Yorkshire's PES License will continue in effect until at least 2025 unless
revoked. Under ordinary circumstances, the license may not be revoked except
on 25 years' 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, or
the insolvency of the licensee.

                CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
  As described under "Business--Business Restructuring", an alternative
ownership structure is being pursued for the generation business. Yorkshire
currently contemplates that such assets may be transferred to a new entity or
to new entities that will be an indirect subsidiary or will be indirect
subsidiaries of the US Parents. It is expected that proceeds from the transfer
of these assets will be used to reduce debt of the Guarantor.
 
  Total assets less current liabilities employed by the generation business at
December 31, 1997 were (Pounds)168 million. Operating income attributable to
the generation business in the nine months ended December 31, 1997 was
(Pounds)12 million. See "Business--Business Restructuring".

                      DESCRIPTION OF THE TRUST SECURITIES
 
  The Trust Securities will be issued pursuant to the terms of the Trust
Agreement. The Trust Agreement will be qualified as an indenture under the
1939 Act. The Property Trustee will act as the indenture trustee with respect
to the Trust, as well as the Trust Securities Guarantee, for purposes of
compliance with the provisions of the 1939 Act. The terms of the Trust
Securities will include those stated in the Trust Agreement, the Delaware
Business Trust Act, and those made part of the Trust Agreement by the 1939
Act. The following summary of the material terms and provisions of the Trust
Securities is subject to, and qualified in its entirety by reference to, the
Trust Agreement, the form of which is filed as an exhibit to the Registration
Statement of which this Prospectus is a part, as well as the 1939 Act.
 
GENERAL
 
  The Trust Agreement authorizes the Administrative Trustees, on behalf of the
Trust, to issue the Trust Securities, which represent undivided beneficial
interests in the assets of the Trust. The Trust Agreement does not permit the
issuance by the Trust of any securities other than the Trust Securities and
the Control Certificate or the incurrence of any indebtedness by the Trust.
Pursuant to the Trust Agreement and the Deposit Agreement, the Property
Trustee will own Book-Entry Interests representing a 100% beneficial interest
in the Junior Subordinated Debentures for the benefit of the Trust and the
holders of the Trust Securities.
 
  Pursuant to the Trust Securities Guarantee, Yorkshire Group will guarantee
the payment of Distributions and payments upon redemption of the Trust
Securities or liquidation of the Trust, but only in each case to the extent of
sufficient funds held by the Trust and available therefor. See "Description of
the Trust Securities Guarantee". The Trust Securities Guarantee does not cover
payment of Distributions on the Trust Securities or amounts payable on
redemption or otherwise when the Trust does not have sufficient funds
available to make such payments. In such event, a remedy of a holder of Trust
Securities is to direct the Property Trustee to enforce its rights under the
Junior Subordinated Debentures and the Debentures Guarantee. In addition, if
Interest Payments or any other payments are due but have not been made on the
Junior Subordinated Debentures, pursuant to the terms of the Debentures
Guarantee, a holder of Trust Securities may institute a legal proceeding
directly against Yorkshire Group without first instituting a legal proceeding
against or requesting or directing that action be taken by the Property
Trustee or any other person or entity for enforcement of payment to such
holder under the Debentures Guarantee in respect of Interest Payments or any
other payments due on the Junior Subordinated Debentures having a principal
amount equal to the aggregate Liquidation Amount of the Trust Securities of
such holder on or after the due dates specified in the Junior Subordinated
Debentures. See "Description of the Trust Securities Guarantee", "Description
of the Debentures Guarantee" and "Relationship Among the Trust Securities, the
Junior Subordinated Debentures, the Trust Securities Guarantee and the
Debentures Guarantee". The above mechanisms and obligations, together with the
US Affiliates' obligations under the Agreement as to Expenses and Liabilities,
constitute a full and unconditional guarantee of the Trust's obligations under
the Trust Securities.
 
DISTRIBUTIONS
 
  Distributions on each Trust Security shall be fixed at the rate of   % per
annum of the stated Liquidation Amount of $25, payable quarterly in arrears on
March 31, June 30, September 30 and December 31 of each year. Distributions
that are in arrears for more than one quarter will accumulate additional
Distributions thereon at the rate of   % per annum thereof, compounded
quarterly ("Additional Distributions"). The term "Distributions" as used
herein includes any Additional Distributions, Additional Amounts or Additional
Interest (as defined herein). Distributions will accumulate from the date of
original issuance of the Trust Securities. The first Distribution Date for the
Trust Securities will be     , 1998. The amount of Distributions payable for
any full period will be computed on the basis of a 360-day year of twelve 30-
day months and for any partial period shall be computed on the basis of the
number of days elapsed in a 360-day year of twelve 30-day months.
 
  So long as no Event of Default under the Indenture has occurred and is
continuing, Yorkshire Finance has the right under the Indenture to defer the
payment of interest on the Junior Subordinated Debentures, at any time and
from time to time, for up to 20 consecutive quarters; provided, however,
Yorkshire Finance cannot defer
 
                                      74
<PAGE>
 
Interest Payments beyond the Stated Maturity of the Junior Subordinated
Debentures. During such an Extension Period, quarterly Distributions on the
Trust Securities would also be deferred (but would continue to accumulate
Additional Distributions thereon at the rate of   % per annum, compounded
quarterly) by the Trust. Until all deferred Interest Payments, together with
interest thereon, have been paid in full, neither Yorkshire Finance nor
Yorkshire Group may, directly or indirectly, (i) declare or pay any cash
dividends or distributions on, or redeem, purchase, acquire, or make a
liquidation payment with respect to, any of its capital stock, (ii) make any
payments on or repay, repurchase or redeem, any of its debt securities
(including other Indenture Securities or other junior subordinated securities
issued by Yorkshire Finance) that rank pari passu with or junior in interest
to the Junior Subordinated Debentures or the Debentures Guarantee,
respectively, (iii) make any payments with respect to any guarantee that ranks
pari passu with or junior to the Junior Subordinated Debentures or the
Debentures Guarantee, respectively, or (iv) make any payments on, or repay,
repurchase or redeem, any of its debt securities held by, make any loans or
advances to, or make any payments with respect to any guarantee of the debt
of, any affiliate, in each case other than (a) dividends or distributions in
shares of, or options, warrants or rights to subscribe for or purchase shares
of, the common stock of Yorkshire Finance or Yorkshire Group and exchanges or
conversions of common stock of one class for common stock of another class,
(b) payments by Yorkshire Group under the Trust Securities Guarantee (or any
other guarantee by Yorkshire Group with respect to any securities issued by
its direct or indirect subsidiaries, provided that the proceeds from the
issuance of such securities were used to purchase other Indenture Securities
or other junior subordinated securities issued by Yorkshire Finance), (c)
payments by Yorkshire Group under the Debentures Guarantee, (d) any dividend
or payment by Yorkshire Group which is applied, directly or indirectly, to any
Tax Payments (as defined below), (e) payments by Yorkshire Group, directly or
indirectly, on the Intercompany Notes or any other promissory notes held by
Yorkshire Finance (or any other direct or indirect wholly-owned subsidiary of
Yorkshire Group) evidencing loans made with the proceeds from the issuance by
Yorkshire Finance (or any other direct or indirect wholly-owned subsidiary of
Yorkshire Group) of securities guaranteed by Yorkshire Group or (f) the
reinvestment of any proceeds received under clause (e) above by Yorkshire
Finance (or any other direct or indirect wholly-owned subsidiary of Yorkshire
Group) in additional debt securities of Yorkshire Group or any of its other
direct or indirect wholly-owned subsidiaries. "Tax Payments" shall mean any
direct or indirect payment by Yorkshire Group to governmental authorities in
respect of UK, US or Cayman Islands taxes arising from the operations of
Yorkshire Group, Yorkshire Finance, the Trust or Yorkshire as and when such
taxes become due and payable. Prior to the termination of any such Extension
Period, Yorkshire Finance may further extend the interest payment period;
provided that, such Extension Period, together with all such previous and
further extensions within such Extension Period, may not exceed 20 consecutive
quarters or the Stated Maturity of the Junior Subordinated Debentures. Upon
the termination of any Extension Period and the payment of all amounts then
due, Yorkshire Finance may commence a new Extension Period, subject to the
above requirements. As a result, there could be multiple Extension Periods of
varying lengths throughout the term of the Junior Subordinated Debentures. See
"Description of the Junior Subordinated Debentures--Option to Defer Payment of
Interest".
 
  Yorkshire Finance currently has no intention of exercising its right to
defer Interest Payments on the Junior Subordinated Debentures. Moreover,
because of the consequences of exercising such right, including a prohibition
on the payment of cash distributions by Yorkshire Finance and Yorkshire Group
with respect to their capital stock, Yorkshire Finance believes that the
likelihood of such exercise is remote.
 
  In the event that a Distribution Date is not a Business Day (as defined
below), payment of the Distributions payable on such date will be made on the
next succeeding day that is a Business Day (and without any interest or other
payment in respect of any such delay) except that, if such Business Day is in
the next succeeding calendar year, payment of such Distributions shall be made
on the immediately preceding Business Day, in each case with the same force
and effect as if made on such date (each date on which Distributions are
payable in accordance with the foregoing, a "Distribution Date"). A "Business
Day" shall mean any day other than a Saturday or a Sunday, or a day on which
banking institutions in The City of New York are authorized or required by law
or executive order to remain closed, or a day on which the corporate trust
office of the Property Trustee or the Indenture Trustee is closed for
business.
 
                                      75
<PAGE>
 
  Distributions on the Trust Securities must be paid and shall be deemed
payable on the Distribution Date only to the extent that the Trust has
sufficient funds available therefor. The payment of Distributions (if and to
the extent the Trust has sufficient funds available for the payment of such
Distributions) is guaranteed by Yorkshire Group as set forth herein under
"Description of the Trust Securities Guarantee". It is anticipated that the
revenue of the Trust available for Distributions on the Trust Securities will
be limited to payments under the Junior Subordinated Debentures or the
Debentures Guarantee. See "Description of the Junior Subordinated Debentures"
and "Description of the Debentures Guarantee". If Yorkshire Finance does not
make payments of principal of or interest on the Junior Subordinated Debentures
or if Yorkshire Group does not make payments with respect to the Debentures
Guarantee, the Trust will not have sufficient funds available to pay
Distributions on the Trust Securities or amounts payable on redemption thereof
or otherwise.
 
  Distributions on the Trust Securities will be payable to the holders of
record as they appear on the register of the Trust on the relevant record
dates, which, as long as the Trust Securities remain in book-entry form, will
be one Business Day prior to the relevant Distribution Date. In the event that
any Trust Securities are not in book-entry form, the relevant record date for
such Trust Securities shall be the date 15 calendar days prior to the relevant
Distribution Date.
 
REDEMPTIONS
 
  Mandatory Redemption. Upon the repayment of the Junior Subordinated
Debentures at Stated Maturity or upon the redemption, in whole or in part, of
the Junior Subordinated Debentures (as described below and in "Description of
the Junior Subordinated Debentures--Redemption"), the proceeds from such
repayment or redemption will be applied to redeem a Like Amount of Trust
Securities, upon not less than 30 nor more than 60 days' notice to each holder
of Trust Securities at its registered address, at the Redemption Price.
 
  Optional Redemption of Junior Subordinated Debentures. Yorkshire Finance will
have the right to redeem the Junior Subordinated Debentures on or after    ,
2003, in whole at any time or in part from time to time, at the Debenture
Redemption Price and thereby cause a mandatory redemption of a Like Amount of
Trust Securities at the Redemption Price. See "Description of the Junior
Subordinated Debentures--Redemption".
 
  Yorkshire Finance will also have the right to redeem the Junior Subordinated
Debentures in whole (but not in part), at the Debenture Redemption Price, if
Yorkshire Finance or Yorkshire Group has or will become obligated to pay
Additional Amounts as provided under "Description of the Junior Subordinated
Debentures--Optional Tax Redemption", and thereby cause a mandatory redemption
of the Trust Securities in whole (but not in part) at the Redemption Price.
 
  Special Event Redemption of Junior Subordinated Debentures. Upon the
occurrence and continuation of a Special Event, Yorkshire Finance shall have
the right, at any time, to redeem the Junior Subordinated Debentures in whole
(but not in part) at the Debenture Redemption Price and thereby cause a
mandatory redemption of the Trust Securities in whole (but not in part) at the
Redemption Price within 90 days following the occurrence of such Special Event.
 
  If a Special Event occurs and Yorkshire Finance does not elect to redeem the
Junior Subordinated Debentures or to dissolve the Trust, the Trust Securities
will remain outstanding and, if such Special Event is a Tax Event, Additional
Interest (as described under "Description of the Junior Subordinated
Debentures--Certain Covenants") may be payable on the Junior Subordinated
Debentures.
 
  "Tax Event" means the receipt by Yorkshire Finance or Yorkshire Group of an
opinion of independent counsel (which may be counsel to Yorkshire Group or its
affiliates) experienced in such matters to the effect that there has been (a)
any amendment to, or change (including any announced prospective change) in,
the laws (or any regulations thereunder) of any supranational federation to
which the UK belongs or the jurisdiction (or any political subdivision or
taxing authority thereof or therein) in which Yorkshire Finance or Yorkshire
Group is incorporated or created, as applicable, or in which Yorkshire Finance
or Yorkshire Group is managed and controlled or has a place of business (each,
a "Taxing Jurisdiction"), (b) any official administrative pronouncement or
judicial decision interpreting, clarifying or applying such laws or regulations
or (c) a
 
                                       76
<PAGE>
 
threatened challenge asserted by a government or taxing authority with respect
to Yorkshire Group or any of its subsidiaries, or a threatened challenge
asserted in writing by a government or taxing authority against any other
taxpayer that has raised capital through the issuance of securities that are
substantially similar to the Junior Subordinated Debentures or the Trust
Securities, which amendment or change is effective or which pronouncement,
clarification, challenge or decision is announced on or after the date of this
Prospectus, and that results in there being more than an insubstantial risk
that (i) Yorkshire Finance is, or will be within 90 days of the date thereof,
subject to income tax within a Taxing Jurisdiction (other than the UK
corporation income tax) with respect to interest accrued or received on the
Intercompany Notes, (ii) Yorkshire Finance is, or will be within 90 days of
the date thereof, subject to more than a de minimis amount of other tax,
duties or other governmental charges, (iii) Interest Payments on the Junior
Subordinated Debentures are not, or within 90 days of the date thereof will
not be, deductible, in whole or in part for (as appropriate) US Federal or UK
corporation income tax purposes, as they accrue by Yorkshire Finance or by a
member of any tax group to which Yorkshire Group belongs or (iv) interest
payable with respect to the Intercompany Notes by Yorkshire Group or its
affiliates is not, or within 90 days of the date thereof will not be,
deductible, in whole or in part, for (as appropriate) US Federal or UK
corporation income tax purposes, as it accrues by one of (as appropriate)
Yorkshire Group, its shareholders or a member of any tax group to which
Yorkshire Group belongs.
 
  "Investment Company Act Event" means that Yorkshire Group or Yorkshire
Finance shall have received an opinion of independent counsel (which may be
counsel to Yorkshire Group or its affiliates) experienced in such matters to
the effect that, as a result of the occurrence of a change in law or
regulation or a change in interpretation or application of law or regulation
by any legislative body, court, governmental agency or regulatory authority
(an "Investment Company Act Change"), there is more than an insubstantial risk
that Yorkshire Finance or Yorkshire Group is or will be considered an
"investment company" that is required to be registered under the Investment
Company Act of 1940, as amended (the "Investment Company Act"), which
Investment Company Act Change becomes effective on or after the date of this
Prospectus.
 
  "Special Event" means the occurrence of a Tax Event or an Investment Company
Act Event.
 
  "Like Amount" means (i) with respect to a repayment or redemption of any
Trust Securities, Trust Securities having a Liquidation Amount equal to that
portion of the principal amount of Junior Subordinated Debentures to be
contemporaneously repaid or redeemed and the proceeds of which will be used to
pay the Redemption Price of such Trust Securities, and (ii) with respect to a
distribution of Junior Subordinated Debentures to holders of the Trust
Securities in connection with a dissolution and liquidation of the Trust or a
payment of any Additional Amounts or Additional Interest on the Trust
Securities, Junior Subordinated Debentures having a principal amount equal to
the Liquidation Amount of the Trust Securities of the holder to whom such
Junior Subordinated Debentures are distributed or such payment is being made.
 
  "Liquidation Amount" means the stated liquidation amount of $25 per Trust
Security.
 
REDEMPTION PROCEDURES
 
  Trust Securities redeemed on each Redemption Date shall be redeemed at the
Redemption Price with the applicable proceeds from the contemporaneous
repayment or redemption of the Junior Subordinated Debentures. Redemptions of
the Trust Securities shall be made, and the Redemption Price shall be deemed
payable, on each Redemption Date only to the extent that the Trust has
sufficient funds available for the payment of such Redemption Price.
 
  If the Property Trustee gives a notice of redemption in respect of any Trust
Securities, then, by 12:00 noon, New York City time, on the Redemption Date,
subject to the immediately preceding paragraph, the Property Trustee will
deposit irrevocably with DTC, so long as the Trust Securities are in book-
entry only form, funds sufficient to pay the applicable Redemption Price and
will give DTC irrevocable instructions and authority to pay the Redemption
Price to the holders of such Trust Securities. See "--Book-Entry Issuance". If
the Trust Securities are no longer in book-entry form, the Property Trustee,
subject to the immediately preceding paragraph, will irrevocably deposit with
the paying agent for the Trust Securities funds sufficient to pay the
applicable Redemption Price and will give such paying agent irrevocable
instructions and authority to pay the
 
                                      77
<PAGE>
 
Redemption Price to the holders thereof upon surrender of their certificates
evidencing such Trust Securities. Notwithstanding the foregoing, Distributions
payable on or prior to the Redemption Date for any Trust Securities called for
redemption shall be payable to the holders of such Trust Securities as of the
relevant record dates for the related Distribution Dates. If notice of
redemption shall have been given and funds deposited as required, then upon
the date of such deposit, all rights of the holders of such Trust Securities
so called for redemption will cease, except the right of the holders of such
Trust Securities to receive the Redemption Price, but without interest on such
Redemption Price, and such Trust Securities will cease to be outstanding. In
the event that any date fixed for redemption of Trust Securities is not a
Business Day, then payment of the Redemption Price payable on such date will
be made on the next succeeding day which is a Business Day (and without any
interest or other payment in respect of any such delay), except that, if such
Business Day falls in the next succeeding calendar year, such payment will be
made on the immediately preceding Business Day, in each case with the same
force and effect as if made on such date. In the event that payment of the
Redemption Price in respect of Trust Securities called for redemption is
improperly withheld or refused and not paid either by the Trust or by
Yorkshire Group pursuant to the Trust Securities Guarantee or the Debentures
Guarantee, Distributions on such Trust Securities will continue to accumulate
at the then applicable rate from the Redemption Date originally established by
the Trust for such Trust Securities to the date such Redemption Price is
actually paid, in which case the actual payment date will be the date fixed
for redemption for purposes of calculating the Redemption Price.
 
  Subject to applicable law (including, without limitation, Rule 14e-1 under
the Exchange Act and any other applicable US Federal securities law),
Yorkshire Group, Yorkshire Finance, the US Affiliates or their affiliates may
at any time and from time to time purchase outstanding Trust Securities by
tender, in the open market or by private agreement.
 
  Payment of the Redemption Price on the Trust Securities and any distribution
of Junior Subordinated Debentures to holders of Trust Securities shall be made
to the holders of record as they appear on the register of the Property
Trustee as of the relevant record date, which, as long as the Trust Securities
remain in book-entry form, will be one Business Day prior to the relevant
Redemption Date or liquidation date, as applicable; provided, however, that in
the event that the Trust Securities are not in book-entry form, the relevant
record date for the Trust Securities shall be the date 15 calendar days prior
to the Redemption Date or liquidation date, as applicable.
 
  If less than all of the Trust Securities are to be redeemed on a Redemption
Date, the particular Trust Securities to be redeemed shall be selected on a
pro rata basis not more than 60 days prior to the Redemption Date by the
Property Trustee from the outstanding Trust Securities not previously called
for redemption, by such method as the Property Trustee shall deem fair and
appropriate, which shall provide for the selection for redemption of portions
(equal to $25 or an integral multiple of $25 in excess thereof) of the
Liquidation Amount of Trust Securities of a denomination larger than $25. The
Property Trustee shall promptly notify the transfer agent and registrar in
writing of the Trust Securities selected for redemption and, in the case of
any Trust Securities selected for partial redemption, the aggregate
Liquidation Amount thereof to be redeemed.
 
DISTRIBUTION OF JUNIOR SUBORDINATED DEBENTURES
   
  The Control Party has the right, at any time, to dissolve the Trust and,
after satisfaction of liabilities to creditors of the Trust, if any, as
provided by applicable law, to cause a Like Amount of Junior Subordinated
Debentures to be distributed to the holders of the Trust Securities in
liquidation of the Trust. Under current US Federal income tax law, provided
the Trust is treated as a grantor trust at the time of such distribution, such
distribution would not be a taxable event to holders of the Trust Securities.
See "Description of the Junior Subordinated Debentures--Distribution of the
Junior Subordinated Debentures" and "Material Income Tax Considerations--US
Federal Income Tax Considerations--Receipt of Junior Subordinated Debentures
or Cash in Certain Circumstances".     
 
  After the date fixed for any distribution of Junior Subordinated Debentures
upon liquidation of the Trust (i) the Trust Securities will no longer be
deemed to be outstanding and the Trust Securities Guarantee will be
discharged, (ii) DTC or its nominee, as the record holder of the Trust
Securities, will receive Global Book-Entry
 
                                      78
<PAGE>
 
Interests (as defined herein) representing a 100% beneficial interest in the
Junior Subordinated Debentures to be delivered upon such distribution, or, if
any Trust Securities are not held by DTC or its nominee, the certificates
representing the Trust Securities will be deemed to represent Book-Entry
Interests representing the Junior Subordinated Debentures having a principal
amount equal to the Liquidation Amount of the Trust Securities, and bearing
accrued and unpaid interest in an amount equal to the accrued and unpaid
Distributions on the Trust Securities until such certificates are presented to
Yorkshire Finance or its agent for transfer or reissuance and (iii) Yorkshire
Finance will use its reasonable efforts to list the Junior Subordinated
Debentures on the NYSE or such other exchanges or other organizations, if any,
on which the Trust Securities are then listed or traded.
 
  There can be no assurance as to the market price for the Junior Subordinated
Debentures that may be distributed if a dissolution and liquidation of the
Trust were to occur. Accordingly, the Junior Subordinated Debentures that an
investor may receive upon a dissolution and liquidation of the Trust may trade
at a discount to the price that such investor paid to purchase its Trust
Securities offered hereby.
 
LIQUIDATION DISTRIBUTION UPON DISSOLUTION
   
  Pursuant to the Trust Agreement, the Trust shall dissolve upon the first to
occur of: (i)     , 2043, (ii) the delivery of written direction to the
Property Trustee by the Control Party at any time to dissolve the Trust (which
direction is optional and wholly within the discretion of Yorkshire Group) and
to distribute the Junior Subordinated Debentures to the holders of the Trust
Securities in liquidation of the Trust (see "--Distribution of Junior
Subordinated Debentures"), (iii) the occurrence of a Bankruptcy Event (as
defined in the Trust Agreement) in respect of Yorkshire Finance, dissolution
or liquidation of Yorkshire Finance, or the dissolution of the Trust pursuant
to a judicial decree or (iv) the payment at Stated Maturity or redemption of
all of the Junior Subordinated Debentures and the consequent redemption of all
of the Trust Securities.     
 
  If an early dissolution occurs as described in clause (ii) or (iii) above,
the Trust shall be liquidated, and the Property Trustee shall distribute to
each holder of Trust Securities a Like Amount of Junior Subordinated
Debentures, unless, in the case of an event described in clause (iii), such
distribution is determined by the Administrative Trustees not to be practical,
in which event such holders will be entitled to receive, out of the assets of
the Trust available for distribution to holders after satisfaction of
liabilities to creditors, an amount equal to the aggregate of the Liquidation
Amount plus accumulated and unpaid Distributions thereon to the date of
payment (such amount being the "Liquidation Distribution"). If such
Liquidation Distribution can be paid only in part because the Trust has
insufficient assets available to pay in full the aggregate Liquidation
Distribution, then the amounts payable directly by the Trust on the Trust
Securities shall be paid on a pro rata basis in proportion to the full
Liquidation Distribution for which the Trust Securities would be entitled.
 
MERGERS, CONVERSIONS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS
   
  The Trust may not merge with or into, convert into, consolidate, amalgamate,
or be replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any corporation or other person, except as
described below or as otherwise described in the Trust Agreement. The Trust
may, at the request of the Control Party, with the consent of the
Administrative Trustees and without the consent of the holders of the Trust
Securities, merge with or into, convert into, consolidate, amalgamate, be
replaced by or convey, transfer or lease its properties and assets
substantially as an entirety to a trust organized as such under the laws of
any jurisdiction; provided that (i) such successor entity either (a) expressly
assumes all of the obligations of the Trust with respect to the Trust
Securities or (b) substitutes for the Trust Securities other securities having
substantially the same terms as the Trust Securities (the "Successor
Securities") so long as the Successor Securities rank the same as the Trust
Securities rank in priority with respect to distributions and payments upon
liquidation, redemption and otherwise, (ii) such successor entity transfers to
the Control Party, directly or indirectly, a control certificate (or similar
instrument) or common securities relating to such successor entity, (iii) the
Control Party expressly appoints a trustee of such successor entity possessing
the same powers and duties as the Property Trustee as the holder, directly or
indirectly, of the Junior Subordinated Debentures, (iv) the Trust Securities
or the Successor Securities are listed or traded, or any Successor Securities
will be listed or traded upon notification of issuance, on any national
securities exchange or other organization on which the Trust Securities are
then listed, if any, (v) such merger, conversion, consolidation, amalgamation,
replacement, conveyance, transfer or lease does not     
 
                                      79
<PAGE>
 
   
cause the Trust Securities (including any Successor Securities) to be
downgraded by any nationally recognized statistical rating organization, (vi)
such merger, conversion, consolidation, amalgamation, replacement, conveyance,
transfer or lease does not adversely affect the rights, preferences and
privileges of the holders of the Trust Securities (including any Successor
Securities) in any material respect, (vii) such successor entity has a purpose
substantially identical to that of the Trust, (viii) prior to such merger,
conversion, consolidation, amalgamation, replacement, conveyance, transfer or
lease, the Control Party has received an opinion from independent counsel
experienced in such matters to the effect that (a) such merger, conversion,
consolidation, amalgamation, replacement, conveyance, transfer or lease does
not adversely affect the rights, preferences and privileges of the holders of
the Trust Securities (including any Successor Securities) in any material
respect, and (b) following such merger, conversion, consolidation,
amalgamation, replacement, conveyance, transfer or lease, neither the Trust,
the Control Party, Yorkshire Finance nor such successor entity will be
required to register as an "investment company" under the Investment Company
Act and (ix) Yorkshire Group or any permitted successor or assignee guarantees
the obligations of such successor entity under the Successor Securities at
least to the extent provided by the Trust Securities Guarantee.
Notwithstanding the foregoing, the Trust shall not, except with the consent of
holders of 100% of the Liquidation Amount of the Trust Securities,
consolidate, amalgamate, merge with or into, convert into, or be replaced by
or convey, transfer or lease its properties and assets substantially as an
entirety to any other entity or permit any other entity to consolidate,
amalgamate, merge with or into, convert into or replace it, if such
consolidation, amalgamation, merger, conversion or replacement would cause (i)
the Trust or the successor entity to be classified as other than a grantor
trust for US Federal income tax purposes, (ii) the Trust or the successor
entity to be classified as a company or other than as a trust whose
beneficiaries are fully entitled to the underlying income of the Trust (a
"Transparent Trust"), in either case, for purposes of UK tax law, (iii) the
Control Party, Yorkshire Finance, the Trust or the successor entity to be
required to register as an "investment company" under the Investment Company
Act or (iv) Yorkshire Finance to be classified as an association or a publicly
traded partnership taxable as a corporation for US Federal income tax
purposes.     
 
VOTING RIGHTS; AMENDMENT OF TRUST AGREEMENT
 
  Except as provided below, under "--Events of Default" and under "Description
of the Trust Securities Guarantee--Amendments and Assignment" and as otherwise
required by law and the Trust Agreement, the holders of the Trust Securities
will have no voting rights.
   
  The Trust Agreement may be amended from time to time by the Securities
Trustees, the Control Party and AEP Resources, as depositor, without the
consent of the holders of the Trust Securities: (i) to cure any ambiguity, to
correct or supplement any provisions in the Trust Agreement that may be
inconsistent with any other provision therein, or to make any other provisions
with respect to matters or questions arising under the Trust Agreement that
shall not be inconsistent with the other provisions of the Trust Agreement;
(ii) to modify, eliminate or add to any provisions of the Trust Agreement to
such extent as shall be necessary to ensure that (a) the Trust will be
classified for US Federal income tax purposes as a grantor trust at all times
that any of the Trust Securities are outstanding, (b) the Trust will be a
Transparent Trust and will not be classified as a company, in either case, for
purposes of UK tax law, (c) neither the Trust, Yorkshire Finance nor Yorkshire
Group will be required to register as an "investment company" under the
Investment Company Act or (d) Yorkshire Finance will not be classified as an
association or a publicly traded partnership taxable as a corporation for US
Federal income tax purposes; or (iii) to effect the acceptance of appointment
by a successor Property Trustee, provided, however, that, except in the case
of clause (ii), such action shall not adversely affect in any material respect
the interests of any holder of Trust Securities, and, in the case of clause
(i), any such amendment of the Trust Agreement shall become effective when
notice thereof is given to the holders of Trust Securities. Except as provided
in the next succeeding paragraph, other amendments to the Trust Agreement may
be made (i) with the consent of the holders of not less than 66 2/3% in
aggregate Liquidation Amount of the Trust Securities then outstanding and (ii)
upon receipt by the Securities Trustees of an opinion of independent counsel
experienced in such matters to the effect that such amendment or the exercise
of any power granted by the Securities Trustees in accordance with such
amendment will not (A) affect the Trust's status as a grantor trust for US
Federal income tax purposes, (B) affect     
 
                                      80
<PAGE>
 
   
the Trust's or Yorkshire Finance's exemption from the Investment Company Act,
(C) cause the Trust to be treated as a company for purposes of UK tax law or
as a trust which is not a Transparent Trust, in either case, for purposes of
UK tax law or (D) affect Yorkshire Finance's status as a partnership for US
Federal income tax purposes.     
   
  Notwithstanding the foregoing, no amendment or modification may be made to
the Trust Agreement if such amendment or modification would cause (i) the
Trust to be classified as other than a grantor trust for US Federal income tax
purposes, (ii) the Trust to be classified as a company or as a trust which is
not a Transparent Trust, in either case, for purposes of UK tax law, (iii) the
Trust, Yorkshire Finance or Yorkshire Group to be required to register as an
"investment company" under the Investment Company Act or (iv) Yorkshire
Finance to be classified as an association or a publicly traded partnership
taxable as a corporation for US Federal income tax purposes.     
 
  Notwithstanding the foregoing, without the consent of each affected holder
of Trust Securities, the Trust Agreement may not be amended to (i) change the
amount or timing of any Distribution on the Trust Securities or otherwise
adversely affect the amount of any Distribution required to be made in respect
of the Trust Securities as of a specified date, (ii) restrict the right of a
holder of Trust Securities to institute suit for the enforcement of any such
payment on or after such date or (iii) change the consent required to amend
the Trust Agreement.
   
  So long as any Junior Subordinated Debentures are held by or for the benefit
of the Property Trustee, the Securities Trustees shall not (i) direct the
time, method and place of conducting any proceeding for any remedy available
to the Indenture Trustee, or executing any trust or power conferred on the
Indenture Trustee with respect to such Junior Subordinated Debentures or the
Debentures Guarantee, (ii) waive any past default that is waivable under the
applicable provisions of the Indenture, (iii) exercise any right to rescind or
annul a declaration that any Interest Payment or other payment with respect to
the Junior Subordinated Debentures or the Debentures Guarantee shall be due
and payable or (iv) consent to any amendment, modification or termination of
the Indenture or the Junior Subordinated Debentures, where such consent shall
be required, or take any other action under the Indenture without, in each
case, obtaining the prior approval of the holders of a majority in aggregate
Liquidation Amount of all outstanding Trust Securities; provided, however,
that where a consent under the Indenture would require the consent of each
holder of Junior Subordinated Debentures affected thereby, no such consent
shall be given by the Securities Trustees without the prior written consent of
each holder of the Trust Securities. The Securities Trustees shall not revoke
any action previously authorized or approved by a vote of the Trust Securities
except by subsequent vote of the holders of the Trust Securities. The Property
Trustee shall notify all holders of Trust Securities of any notice of default
with respect to the Junior Subordinated Debentures. In addition to obtaining
the foregoing approvals of the holders of the Trust Securities, prior to
taking any of the foregoing actions, the Securities Trustees shall obtain an
opinion of independent counsel experienced in such matters to the effect that
(i) the Trust will not be classified as other than a grantor trust for US
Federal income tax purposes on account of such action, (ii) the Trust will be
a Transparent Trust and will not be classified as a company for purposes of UK
tax law on account of such action, (iii) neither the Trust, Yorkshire Finance
nor Yorkshire Group will be required to register as an "investment company"
under the Investment Company Act on account of such action and (iv) Yorkshire
Finance will not be classified as an association or a publicly traded
partnership taxable as a corporation for US Federal income tax purposes.     
 
  Any required approval of holders of Trust Securities may be given at a
meeting of holders of Trust Securities convened for such purpose or pursuant
to written consent. The Administrative Trustees will cause a notice of any
meeting at which holders of Trust Securities are entitled to vote, or of any
matter upon which action by written consent of such holders is to be taken, to
be given to each holder of record of Trust Securities in the manner set forth
in the Trust Agreement.
 
  No vote or consent of the holders of Trust Securities will be required for
the Trust to redeem and cancel the Trust Securities in accordance with the
Trust Agreement.
 
  Notwithstanding that holders of Trust Securities are entitled to vote or
consent under any of the circumstances described above, any of the Trust
Securities that are owned by Yorkshire Group, or any of its affiliates, shall,
for purposes of such vote or consent, be treated as if they were not
outstanding.
 
                                      81

EVENTS OF DEFAULT
 
  Any one of the following events constitutes an "Event of Default" under the
Trust Agreement (a "Trust Agreement Event of Default") with respect to the
Trust Securities issued thereunder (whatever the reason for such Trust
Agreement Event of Default, and whether it shall be voluntary or involuntary
or be effected by operation of law or pursuant to any judgment, decree or
order of any court or any order, rule or regulation of any administrative or
governmental body):
 
    (i) the occurrence of an Event of Default under the Indenture (see
  "Description of the Junior Subordinated Debentures--Indenture Events of
  Default"); or
 
    (ii) default by the Trust in the payment of any Distribution when it
  becomes due and payable (subject to an Extension Period) and the
  continuation of such default for a period of 60 days; or
 
    (iii) default by the Trust in the payment of any Redemption Price of any
  Trust Security when it becomes due and payable; or
 
    (iv) default in the performance, or breach, of any covenant or warranty
  of the Securities Trustees in the Trust Agreement (other than a covenant or
  warranty a default in the performance of which is covered by clause (ii) or
  (iii) above), and continuation of such default or breach for a period of 60
  days after there has been given, by registered or certified mail, to such
  Securities Trustees by the holders of at least 33% in aggregate Liquidation
  Amount of the outstanding Trust Securities a written notice specifying such
  default or breach and requiring it to be remedied and stating that such
  notice is a "Notice of Default" under the Trust Agreement; or
 
    (v) the occurrence of certain events of bankruptcy or insolvency with
  respect to the Trust.
   
  Within 90 days after the occurrence of any Trust Agreement Event of Default,
the Property Trustee shall transmit notice of any default known to the
Property Trustee to the holders of Trust Securities, the Control Party and
Yorkshire Finance, unless such Trust Agreement Event of Default shall have
been cured or waived.     
 
  If a Trust Agreement Event of Default occurs and is continuing, then,
pursuant to the Trust Agreement, holders of a majority in aggregate
Liquidation Amount of Trust Securities have the right to direct the time,
method and place of conducting any proceeding for remedy available to the
Property Trustee or to direct the exercise of any trust or power conferred
upon the Property Trustee under the Trust Agreement, including the right to
direct the Property Trustee under the Trust Agreement to exercise the remedies
available to it as indirect holder of the Junior Subordinated Debentures and
as direct beneficiary of the Debentures Guarantee. Furthermore, if the
Property Trustee fails to enforce its rights under the Debentures Guarantee, a
holder of Trust Securities may, to the fullest extent permitted by applicable
law, institute a legal proceeding directly against Yorkshire Group to enforce
the Property Trustee's rights with respect to the Debentures Guarantee without
first instituting any legal proceeding against or requesting or directing that
action be taken by the Property Trustee or the Trust. Notwithstanding the
foregoing, a holder of Trust Securities may institute a legal proceeding
directly against Yorkshire Group without first instituting a legal proceeding
against the Property Trustee or any other person or entity for enforcement of
payment to such holder under the Debentures Guarantee in respect of Interest
Payments or any other payments due on the Junior Subordinated Debentures
having an aggregate principal amount equal to the aggregate Liquidation Amount
of the Trust Securities of such holder on or after the due dates specified in
the Junior Subordinated Debentures. See "Relationship Among the Trust
Securities, the Junior Subordinated Debentures, the Trust Securities Guarantee
and the Debentures Guarantee".
   
  Unless an Event of Default under the Indenture shall have occurred and be
continuing, any Securities Trustee may be removed at any time by act of the
holder of the Control Certificate. If an Event of Default under the Indenture
has occurred and is continuing, the Property Trustee and the Delaware Trustee
may be removed at such time by act of the holders of a majority in aggregate
Liquidation Amount of the Trust Securities. In no event will the holders of
the Trust Securities have the right to vote, appoint, remove or replace the
Administrative Trustees, which rights are vested exclusively with the Control
Party. No resignation or removal of any Securities Trustee and no appointment
of a successor shall be effective until the acceptance of appointment by the
successor trustee in accordance with the requirements of the Trust Agreement.
    
                                      82

PAYMENT AND PAYING AGENCY
 
  Payments in respect of Trust Securities held by DTC or its nominee shall be
made as described under "--Book-Entry Issuance". If any Trust Securities are
not held by DTC or its nominee, such payments shall be made by check mailed to
the address of the holder entitled thereto as such address shall appear on the
register of the Trust. The paying agent shall initially be The Bank of New
York in New York, New York.
 
BOOK-ENTRY ISSUANCE
 
  DTC will act as initial securities depositary for the Trust Securities. The
Trust Securities will be issued as fully-registered global securities in book-
entry form registered in the name of Cede & Co. (DTC's partnership nominee).
One or more fully-registered global certificates in book-entry form will be
issued for the Trust Securities representing the aggregate total number of the
Trust Securities and will be deposited with DTC or its custodian.
 
  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 Exchange Act. DTC
holds securities that its participants ("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. Direct Participants
include securities brokers and dealers, banks, trust companies, clearing
corporations and certain other organizations ("Direct Participants"). DTC is
owned by a number of its Direct Participants and by the NYSE, 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 Direct Participants, either directly or
indirectly ("Indirect Participants"). The rules applicable to DTC and its
Participants are on file with the Commission.
 
  Purchases of Trust Securities within the DTC system must be made by or
through Direct Participants, which will receive a credit for the Trust
Securities on DTC's records. The ownership interest of each actual purchaser
of each Trust Security ("Beneficial Owner") is in turn to be recorded on the
Direct and Indirect Participants' records. Beneficial Owners will not receive
written confirmation from DTC of their purchases, but Beneficial Owners are
expected to receive written confirmations providing details of the
transactions, as well as periodic statements of their holdings, from the
Direct or Indirect Participants through which the Beneficial Owners purchased
Trust Securities. Transfers of ownership interests in the Trust Securities are
to be accomplished by entries made on the books of Participants acting on
behalf of Beneficial Owners. Beneficial Owners will not receive certificates
representing their ownership interests in Trust Securities, except in the
event that use of the book-entry system for the Trust Securities is
discontinued.
 
  To facilitate subsequent transfers, all of the Trust Securities deposited by
Participants with DTC are registered in the name of DTC's partnership nominee,
Cede & Co. The deposit of Trust Securities with DTC and their registration in
the name of Cede & Co. effect no change in beneficial ownership. DTC has no
knowledge of the actual Beneficial Owners of the Trust Securities; DTC's
records reflect only the identity of the Direct Participants to whose accounts
such Trust Securities are credited, which may or may not be the Beneficial
Owners. The Participants will remain responsible for keeping account of their
holdings on behalf of their customers.
 
  Conveyance of notices and other communications by DTC to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to Beneficial Owners will be governed
by arrangements among them, subject to any statutory or regulatory
requirements as may be in effect from time to time.
 
  Redemption notices shall be sent to Cede & Co. If less than all of the Trust
Securities are being redeemed, DTC will determine the amount of the interest
of each Direct Participant to be redeemed in accordance with its current
procedures.
 
 
                                      83
<PAGE>
 
  Neither DTC nor Cede & Co. will consent or vote with respect to Trust
Securities. Under its usual procedures, DTC mails an omnibus proxy (the
"Omnibus Proxy") to the Property Trustee as soon as possible after the record
date. The Omnibus Proxy assigns Cede & Co.'s consenting or voting rights to
those Direct Participants to whose accounts such Trust Securities are credited
on the record date (identified in a listing attached to the Omnibus Proxy).
 
  Distribution payments on the Trust Securities will be made to DTC in
immediately available funds. DTC's current practice, upon receipt of any
payment in respect of securities such as the Trust Securities, is to credit
Direct Participants' accounts on the relevant payment date in accordance with
their respective holdings shown on DTC's records unless DTC has reason to
believe that it will not receive payment on such payment date. Payments by
Participants to Beneficial Owners will be governed by standing instructions
and customary practices and will be the responsibility of such Participant and
not of DTC, the Trust, Yorkshire Group or Yorkshire Finance, subject to any
statutory or regulatory requirements as may be in effect from time to time.
Payment of Distributions to DTC is the responsibility of the Property Trustee,
disbursement of such payments to Direct Participants is the responsibility of
DTC, and disbursements of such payments to the Beneficial Owners is the
responsibility of Direct and Indirect Participants.
 
  If (i) DTC discontinues providing its services as securities depositary with
respect to the Trust Securities at any time by giving reasonable notice to the
Trust or Yorkshire Finance, (ii) the Trust or Yorkshire Finance decides to
discontinue use of the system of book-entry transfers through DTC (or a
successor depositary) and a successor securities depositary is not obtained or
(iii) the Trust fails to pay any amounts due and payable in respect of the
Trust Securities or Yorkshire Group fails to pay any amounts payable in
respect of the Trust Securities Guarantee, as required by their respective
terms, definitive Trust Securities certificates will be printed and delivered.
 
  The information in this section concerning DTC and DTC's book-entry system
has been obtained from sources that the Trust and Yorkshire Finance believe to
be accurate, but the Trust and Yorkshire Finance assume no responsibility for
the accuracy thereof. Neither the Trust nor Yorkshire Finance has any
responsibility for the performance by DTC or its Participants of their
respective obligations as described herein or under the rules and procedures
governing their respective operations.
 
REGISTRAR AND TRANSFER AGENT
 
  The Bank of New York will act as registrar and transfer agent for the Trust
Securities.
 
  Registration of transfers of Trust Securities will be effected without
charge by or on behalf of the Trust, but upon payment of any tax or other
governmental charges that may be imposed in connection with any transfer or
exchange. The Trust will not be required to register or cause to be registered
the transfer of Trust Securities after the date such Trust Securities have
been called for redemption.
 
MISCELLANEOUS
   
  The Administrative Trustees are authorized and directed to conduct the
affairs of and to operate the Trust in such a way that (i) neither the Control
Party, Yorkshire Finance nor the Trust will be deemed to be an "investment
company" required to be registered under the Investment Company Act, (ii) the
Trust will not be classified other than as a grantor trust for US Federal
income tax purposes, (iii) the Trust will be classified as a Transparent Trust
and not as a company for purposes of UK tax law, (iv) Yorkshire Finance will
not be classified as an association or a publicly traded partnership taxable
as a corporation for US Federal income tax purposes and (v) the Junior
Subordinated Debentures will be treated as indebtedness for US Federal income
tax purposes. In this connection, the Control Party and the Administrative
Trustees are authorized to take any action, not inconsistent with applicable
law, the certificate of trust or the Trust Agreement, that the Administrative
Trustees determine in their discretion consider to be necessary or desirable
for such purposes, as long as such action does not materially and adversely
affect the interests of the holders of the Trust Securities.     
 
  The Trust and the holders of Trust Securities (by acceptance of a beneficial
interest in a Trust Security) will agree to treat the Junior Subordinated
Debentures as indebtedness of Yorkshire Finance for all US Federal income tax
purposes.

                 DESCRIPTION OF THE TRUST SECURITIES GUARANTEE
 
  The Trust Securities Guarantee will be executed and delivered by Yorkshire
Group (concurrently with the issuance by the Trust of the Trust Securities)
for the benefit of the holders from time to time of the Trust Securities. The
Bank of New York will act as indenture trustee (the "Guarantee Trustee") under
the Trust Securities Guarantee for the purposes of compliance with the 1939
Act. The Trust Securities Guarantee will be qualified as an indenture under
the 1939 Act. This summary of material provisions of the Trust Securities
Guarantee is subject to, and qualified in its entirety by reference to, all of
the provisions of the Trust Securities Guarantee and the 1939 Act. The form of
the Trust Securities Guarantee has been filed as an exhibit to the
Registration Statement of which this Prospectus forms a part. The Guarantee
Trustee will hold the Trust Securities Guarantee for the benefit of the
holders of the Trust Securities.
 
GENERAL
 
  Yorkshire Group will irrevocably agree to pay in full on a subordinated
basis, to the extent set forth herein, the Guarantee Payments (as defined
below), to the extent not paid by, or on behalf of, the Trust to the holders
of the Trust Securities, as and when due, regardless of any defense, right of
set-off or counterclaim that the Trust may have or assert other than the
defense of payment. The following payments with respect to the Trust
Securities, to the extent not paid by or on behalf of the Trust, will be
subject to the Trust Securities Guarantee (without duplication): (i) any
accumulated and unpaid Distributions required to be paid on the Trust
Securities, to the extent that the Trust has sufficient funds available
therefor, (ii) the Redemption Price with respect to any Trust Securities
called for redemption to the extent that the Trust has sufficient funds
available therefor or (iii) upon a voluntary or involuntary dissolution,
winding-up or liquidation of the Trust (unless the Junior Subordinated
Debentures are distributed to holders of the Trust Securities), the lesser of
(a) the aggregate of the Liquidation Amount and all accumulated and unpaid
Distributions on the Trust Securities to the date of payment, to the extent
sufficient funds held are available therefor, and (b) the amount of assets of
the Trust remaining available for distribution to holders of the Trust
Securities (the "Guarantee Payments"). Yorkshire Group's obligation to make a
Guarantee Payment may be satisfied by direct payment of the required amounts
by Yorkshire Group to the holders of the Trust Securities or by causing the
Trust to pay such amounts to such holders.
 
  The Trust Securities Guarantee will be an irrevocable guarantee on a
subordinated basis of the Trust's obligations under the Trust Securities, but
will apply only to the extent that the Trust has sufficient funds available to
make such payments.
 
  If Yorkshire Finance does not make payments of principal of or interest on
the Junior Subordinated Debentures or Yorkshire Group does not make payments
pursuant to the Debentures Guarantee, it is expected that the Trust will not
pay Distributions on the Trust Securities and will not have sufficient funds
available therefor.
 
  The Trust Securities Guarantee, the Debentures Guarantee, the Indenture, the
Junior Subordinated Debentures, the Trust Agreement and the Agreement as to
Expenses and Liabilities, when taken together, will effectively provide a full
and unconditional guarantee, on a subordinated basis, of the Trust's
obligations under the Trust Securities. No single document standing alone or
operating in conjunction with fewer than all of the other documents
constitutes such a guarantee. It is only the combined operation of these
documents that has the effect of providing a full, irrevocable and
unconditional guarantee of the Trust's obligations under the Trust Securities.
See "Relationship Among the Trust Securities, the Junior Subordinated
Debentures, the Trust Securities Guarantee and the Debentures Guarantee".
 
  During an Extension Period, Yorkshire Group's obligations to make payments
under the Trust Securities Guarantee will be suspended. See "Description of
the Junior Subordinated Debentures--Option to Defer Payment of Interest".
 
                                      85
<PAGE>
 
STATUS OF THE TRUST SECURITIES GUARANTEE
 
  Yorkshire Group's obligations under the Trust Securities Guarantee to make
the Guarantee Payments will constitute an unsecured obligation of Yorkshire
Group and will rank (i) subordinate and junior in right of payment to all
Senior Debt of Yorkshire Group (which excludes those obligations or
liabilities made pari passu or subordinate by their terms), (ii) pari passu
with the most senior preferred or preference stock now or hereafter issued by
Yorkshire Group and with any guarantee now or hereafter entered into by
Yorkshire Group in respect of any preferred or preference securities of any
affiliate of Yorkshire Group, and (iii) senior to all common stock of
Yorkshire Group. The terms of the Trust Securities will provide that each
holder of Trust Securities by acceptance thereof agrees to the subordination
provisions and other terms of the Trust Securities Guarantee.
 
  The Trust Securities Guarantee will constitute a guarantee of payment and
not of collection (that is, the guaranteed party may institute a legal
proceeding directly against Yorkshire Group to enforce its rights under the
guarantee without first instituting a legal proceeding against any other
person or entity).
 
  The Trust Securities Guarantee will not be discharged except by payment of
the Guarantee Payments in full to the extent not paid by or on behalf of the
Trust or upon distribution to the holders of the Trust Securities of the
Junior Subordinated Debentures. The Trust Securities Guarantee does not place
a limitation on the amount of additional Senior Debt that may be incurred by
Yorkshire Group. Yorkshire Group expects from time to time to incur additional
indebtedness constituting Senior Debt.
 
AMENDMENTS AND ASSIGNMENT
 
  Except with respect to any changes that do not materially adversely affect
the rights of holders of the Trust Securities (in which case no vote will be
required), the Trust Securities Guarantee may not be amended without the prior
approval of the holders of a majority of the aggregate Liquidation Amount of
the outstanding Trust Securities. The manner of obtaining any such approval is
set forth under "Description of the Trust Securities--Voting Rights; Amendment
of Trust Agreement". All guarantees and agreements contained in the Trust
Securities Guarantee shall bind the successors, assigns, receivers, trustees
and representatives of the Yorkshire Group and shall inure to the benefit of
the holders of the Trust Securities then outstanding.
 
EVENTS OF DEFAULT
 
  An event of default under the Trust Securities Guarantee will occur upon the
failure of Yorkshire Group to perform any of its payment obligations
thereunder. The holders of a majority in aggregate Liquidation Amount of the
Trust Securities have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Guarantee Trustee in
respect of the Trust Securities Guarantee or to direct the exercise of any
trust or power conferred upon the Guarantee Trustee under the Trust Securities
Guarantee.
 
  Any holder of the Trust Securities may institute a legal proceeding directly
against Yorkshire Group to enforce its rights under the Trust Securities
Guarantee without first instituting a legal proceeding against the Trust, the
Guarantee Trustee or any other person or entity.
 
INFORMATION CONCERNING THE GUARANTEE TRUSTEE
 
  The Guarantee Trustee, other than prior to the occurrence and after the
curing of a default by the Yorkshire Group in performance of the Trust
Securities Guarantee, undertakes to perform only such duties as are
specifically set forth in the Trust Securities Guarantee and, after default
with respect to the Trust Securities Guarantee, must exercise the same degree
of care and skill as a prudent person would exercise or use in the conduct of
his or her own affairs. Notwithstanding this provision, the Guarantee Trustee
is under no obligation to exercise any of the powers vested in it by the Trust
Securities Guarantee at the request of any holder of the Trust Securities
unless it is offered reasonable indemnity against the costs, expenses and
liabilities that might be incurred thereby.
 
                                      86
<PAGE>
 
  The Bank of New York, the Guarantee Trustee, also serves as the Property
Trustee and the Indenture Trustee. Yorkshire Group and certain of its
affiliates maintain banking relationships with The Bank of New York.
 
TERMINATION OF THE TRUST SECURITIES GUARANTEE
 
  The Trust Securities Guarantee will terminate and be of no further force and
effect upon full payment of the Redemption Price of the Trust Securities, upon
full payment of the amounts payable upon liquidation of the Trust or upon
distribution of the Junior Subordinated Debentures to the holders of the Trust
Securities. The Trust Securities Guarantee will continue to be effective or
will be reinstated, as the case may be, if at any time any holder of the Trust
Securities must restore payment of any sums paid under the Trust Securities or
the Trust Securities Guarantee.
 
GOVERNING LAW
 
  The Trust Securities Guarantee will be governed by and construed in
accordance with the laws of the State of New York.
 
THE AGREEMENT AS TO EXPENSES AND LIABILITIES
 
  Pursuant to an expense agreement ( the "Agreement as to Expenses and
Liabilities"), the US Affiliates will irrevocably and unconditionally
guarantee to each person or entity to whom the Trust becomes indebted or
liable the full payment of any indebtedness, expenses or liabilities of the
Trust, other than obligations of the Trust to pay to the holders of the Trust
Securities or other similar interests in the Trust, the amounts due such
holders pursuant to the terms of the Trust Securities or such other similar
interests, as the case may be.

               DESCRIPTION OF THE JUNIOR SUBORDINATED DEBENTURES
 
  The Junior Subordinated Debentures are to be issued under the Indenture with
terms corresponding to the terms of the Trust Securities. This summary of
material terms and provisions of the Junior Subordinated Debentures and the
Indenture is subject to, and is qualified in its entirety by reference to, the
Indenture, the form of which is filed as an exhibit to the Registration
Statement of which this Prospectus forms a part, and the 1939 Act.
 
GENERAL
 
  Concurrently with the issuance of the Trust Securities, the Trust will
invest the proceeds thereof in the Junior Subordinated Debentures issued by
Yorkshire Finance. The Junior Subordinated Debentures will be unsecured and
will rank junior and be subordinate in right of payment to all Senior Debt of
Yorkshire Finance and will rank pari passu with any other series of Indenture
Securities (as defined below) issued by Yorkshire Finance. Additional series
of securities (together with the Junior Subordinated Debentures, the
"Indenture Securities") may be issued, without limitation as to amount, under
the Indenture and the Indenture does not limit the incurrence or issuance of
other secured or unsecured securities of Yorkshire Finance, whether under the
Indenture, any other indenture that Yorkshire Finance may enter into in the
future or otherwise. See "--Subordination". Application will be made to list
the Junior Subordinated Debentures on the Luxembourg Stock Exchange.
 
  The entire principal amount of the Junior Subordinated Debentures will
mature and become due and payable, together with any accrued and unpaid
interest thereon, on     , 2038.
 
 
INTEREST
 
  The Junior Subordinated Debentures will bear interest at the rate of  % per
annum of the principal amount thereof, payable quarterly in arrears on March
31, June 30, September 30 and December 31 of each year (each, an "Interest
Payment Date"), commencing     , 1998, initially, through a Paying Agent to
the Book-Entry Depositary (as defined under "--Form, Book-Entry Procedures and
Transfer"), as the holder of the Global Debentures (as defined under "--Form,
Book-Entry Procedures and Transfer"), and, otherwise, as described under "--
Form, Book-Entry Procedures and Transfer--Payments on the Junior Subordinated
Debentures". The amount of interest payable for any period will be computed on
the basis of a 360-day year of twelve 30-day months. In the event that any
date on which an Interest Payment is payable on the Junior Subordinated
Debentures is not a Business Day, then the Interest Payment payable on such
date will be made on the next succeeding day which is a Business Day (and
without any interest or other payment in respect of any such delay), except
that, if such Business Day is in the next succeeding calendar year, such
payment shall be made on the immediately preceding Business Day, in each case
with the same force and effect as if made on the date such payment was
originally payable. Interest Payments that are in arrears for more than one
quarter will accrue additional interest (to the extent permitted by law) at
the rate of  % per annum thereof, compounded quarterly. The term "interest" as
used herein shall include quarterly Interest Payments, interest on quarterly
Interest Payments in arrears, Additional Amounts and Additional Interest, as
applicable.
 
OPTION TO DEFER PAYMENT OF INTEREST
 
  So long as no Event of Default under the Indenture has occurred and is
continuing, Yorkshire Finance has the right under the Indenture during the
term of the Junior Subordinated Debentures to defer Interest Payments, at any
time or from time to time, for up to 20 consecutive quarters; provided,
however, that Yorkshire Finance cannot defer Interest Payments beyond the
Stated Maturity of the Junior Subordinated Debentures. Until all deferred
Interest Payments together with interest thereon have been paid in full,
interest will continue to accrue, together with interest thereon at the stated
rate of interest on the Junior Subordinated Debentures, to the extent
permitted by law.
 
  In the event that Yorkshire Finance exercises this right, until all deferred
Interest Payments together with interest thereon have been paid in full,
neither Yorkshire Finance nor Yorkshire Group may, directly or indirectly, (i)
declare or pay any cash dividends or distributions on, or redeem, purchase,
acquire, or make a
 
                                      88
<PAGE>
 
liquidation payment with respect to, any of its capital stock, (ii) make any
payments on, or repay, repurchase or redeem, any of its debt securities
(including other Indenture Securities or other junior subordinated securities
issued by Yorkshire Finance) that rank pari passu with or junior in interest
to the Junior Subordinated Debentures or the Debentures Guarantee,
respectively, (iii) make any payments with respect to any guarantee that ranks
pari passu with or junior in interest to the Junior Subordinated Debentures or
the Debentures Guarantee, respectively, or (iv) make any payments on, or
repay, repurchase or redeem, any of its debt securities held by, make any
loans or advances to, or make any payments with respect to any guarantee of
the debt of, any affiliate, in each case other than (a) dividends or
distributions in shares of, or options, warrants or rights to subscribe for or
purchase shares of, common stock of Yorkshire Finance or Yorkshire Group and
exchanges or conversions of common stock of one class for common stock of
another class, (b) payments by Yorkshire Group under the Trust Securities
Guarantee (or any other guarantee by Yorkshire Group with respect to any
securities of any issued by its direct or indirect subsidiaries, provided that
the proceeds from the issuance of such securities were used to purchase other
Indenture Securities or other junior subordinated securities issued by
Yorkshire Finance), (c) payments by Yorkshire Group under the Debentures
Guarantee, (d) any dividend or payment by Yorkshire Group which is applied,
directly or indirectly, to any Tax Payments, (e) payments by Yorkshire Group,
directly or indirectly, on the Intercompany Notes or any other promissory
notes held by Yorkshire Finance (or any other direct or indirect wholly-owned
subsidiary of Yorkshire Group) evidencing loans made with the proceeds from
the issuance by Yorkshire Finance (or any other direct or indirect wholly-
owned subsidiary of Yorkshire Group) of securities guaranteed by Yorkshire
Group or (f) the reinvestment of any proceeds received under clause (e) above
by Yorkshire Finance (or any other direct or indirect wholly-owned subsidiary
of Yorkshire Group) in additional debt securities of Yorkshire Group or any of
its other direct or indirect wholly-owned subsidiaries.
 
  Prior to the termination of any such Extension Period, Yorkshire Finance may
further extend the interest payment period; provided that, such Extension
Period, together with all such previous and further extensions within such
Extension Period, may not exceed 20 consecutive quarters or the Stated
Maturity of the Junior Subordinated Debentures. Upon the termination of any
Extension Period and the payment of all amounts then due, Yorkshire Finance
may commence a new Extension Period, subject to the above requirements. As a
result, there could be multiple Extension Periods of varying lengths
throughout the term of the Junior Subordinated Debentures.
 
  Yorkshire Finance must give the Property Trustee and the Indenture Trustee
notice of its intention to defer Interest Payments at least one Business Day
prior to the earlier of (i) the next succeeding Interest Payment Date and (ii)
the date Yorkshire Finance is required to give notice to the NYSE or other
applicable self-regulatory organization or to holders of the Junior
Subordinated Debentures of the record date or Interest Payment Date, but in
any event not less than one Business Day prior to such record date. The
Property Trustee shall give notice of Yorkshire Finance's intention to defer
Interest Payments to the holders of the Trust Securities within five Business
Days of the receipt of notice thereof.
 
REDEMPTION
 
  The Junior Subordinated Debentures are redeemable prior to maturity at the
option of Yorkshire Finance (i) on or after    , 2003, in whole at any time or
in part from time to time, (ii) at any time, in whole (but not in part) within
90 days following the occurrence of a Special Event or (iii) at any time, in
whole (but not in part), if Yorkshire Finance or Yorkshire Group has or will
become obligated to pay Additional Amounts, as provided under "--Optional Tax
Redemption", in each case, at the Debenture Redemption Price.
 
  The proceeds of any such redemption will be used by the Trust to redeem the
Trust Securities in accordance with their terms. Yorkshire Finance may not
redeem less than all of the Junior Subordinated Debentures unless all accrued
and unpaid interest, if any, has been paid in full on all outstanding Junior
Subordinated Debentures for all interest periods terminating on or prior to
the Redemption Date.
 
  Notice of any redemption will be mailed at least 30 days but not more than
60 days before the Redemption Date to each holder of Junior Subordinated
Debentures to be redeemed at such holder's registered address. Unless
Yorkshire Finance defaults in payment of the Debenture Redemption Price, on
and after the Redemption Date interest shall cease to accrue on the Junior
Subordinated Debentures or portions thereof called for redemption.
 
                                      89
<PAGE>
 
ADDITIONAL AMOUNTS
 
  All payments in respect of the Junior Subordinated Debentures and all
payments made pursuant to the Debentures Guarantee 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
a Taxing Jurisdiction or by or within any political subdivision thereof or any
authority therein or thereof having power to tax ("Gross-Up Taxes"), unless
such withholding or deduction is required by law. In the event of any such
withholding or deduction, Yorkshire Finance or Yorkshire Group, as the case
may be, shall pay to the relevant holder of Junior Subordinated Debentures the
amount that would otherwise have been due to such holder in the absence of
such withholding or deduction, except that no Additional Amounts shall be
payable:
 
    (a) to, or to a person on behalf of, a holder who is liable for such
  Gross-Up Taxes in respect of the Junior Subordinated Debentures or the
  Debentures Guarantee by reason of such holder having some connection with
  the relevant Taxing Jurisdiction (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, such Taxing Jurisdiction)
  other than the mere holding of a Junior Subordinated Debenture or the
  receipt of any payment in respect thereof or in respect of the Debentures
  Guarantee;
 
    (b) to, or to a person on behalf of, a holder who presents a Junior
  Subordinated Debenture (whenever 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 Junior Subordinated Debenture 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 Junior
  Subordinated Debenture (where presentation is required) in the UK or Cayman
  Islands;
 
    (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
  Debenture (as defined under "--Form, Book-Entry Procedures and Transfer")
  issued pursuant to an Optional Definitive Security Request (as defined
  under "--Form, Book-Entry Procedures and Transfer").
 
  Such Additional Amounts will also not be payable where, had the beneficial
owner of the Junior Subordinated Debentures (or any interest therein) been the
holder of the Junior Subordinated Debentures, he would not have been entitled
to payment of Additional Amounts by reason of any one or more of the clauses
(a) through (e) above. If Yorkshire Group or Yorkshire Finance, as applicable,
shall determine that Additional Amounts will not be payable because of the
immediately preceding sentence, Yorkshire Group or Yorkshire Finance, as
applicable, 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 Book-Entry Depositary (as defined
herein) or the Indenture 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.
 
  Any reference in this Prospectus to any payments with respect to the Junior
Subordinated Debentures or pursuant to the Debentures Guarantee shall be
deemed to include any such Additional Amounts payable in connection therewith.
 
OPTIONAL TAX REDEMPTION
 
  If (a) Yorkshire Group or Yorkshire Finance satisfies the Indenture Trustee
prior to the giving of a notice as provided below that it has or will become
obligated to pay Additional Amounts with respect to the Junior Subordinated
Debentures or the Debentures Guarantee as a result of either (x) any change
in, or amendment to, the laws or regulations of a Taxing Jurisdiction 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 Debentures pursuant to an Optional Definitive Security
Request or clause (i) or
 
                                      90
<PAGE>
 
(ii) of the second sentence of "--Form, Book-Entry Procedures and Transfer--
Definitive Registered Debentures" and (b) such obligation cannot be avoided by
Yorkshire Group or Yorkshire Finance taking reasonable measures available to
it, Yorkshire Finance may, at its option, on giving not more than 60 nor less
than 30 days' notice to the holders, redeem, as a whole but not in part, the
Junior Subordinated Debentures at the Debenture Redemption Price provided that
no such notice of redemption shall be given earlier than 90 days prior to the
earliest date on which Yorkshire Group or Yorkshire Finance would be obligated
to pay such Additional Amounts were a payment in respect of the Junior
Subordinated Debentures then due. Prior to the publication of any notice of
redemption pursuant to this paragraph, Yorkshire Finance shall deliver to the
Indenture Trustee a certificate signed by a director of Yorkshire Finance
stating that the obligation referred to in clause (a) above cannot be avoided
by Yorkshire Group or Yorkshire Finance taking reasonable measures available
to it, and the Indenture Trustee shall accept such certificate as sufficient
evidence of the condition precedent set forth in clause (b) above, in which
event it shall be conclusive and binding on the holders.
 
  In the event that the Global Debentures are redeemed in whole or in part
pursuant to this provision or "--Redemption" above, the Book-Entry Depositary
will redeem, from the amount received by it in respect of the redemption of
the Global Debentures an equal amount of the related Book-Entry Interests
initially held by the Property Trustee. The redemption price payable in
connection with the redemption of such Book-Entry Interests will be equal to
the amount received by the Book-Entry Depositary in connection with the
redemption of the Global Debentures.
 
DISTRIBUTION OF THE JUNIOR SUBORDINATED DEBENTURES
   
  At any time, the Control Party has the right at any time to dissolve the
Trust, and, in such event, cause a Like Amount of Junior Subordinated
Debentures to be distributed to the holders of the Trust Securities in
liquidation of the Trust after satisfaction of liabilities to creditors of the
Trust, if any, as provided by applicable law. See "Description of the Trust
Securities--Distribution of Junior Subordinated Debentures". If distributed to
holders of the Trust Securities in liquidation of the Trust, the Junior
Subordinated Debentures will initially be issued as described under "--Form,
Book-Entry Procedures and Transfer". If the Junior Subordinated Debentures are
distributed to the holders of the Trust Securities upon the dissolution and
liquidation of the Trust, Yorkshire Finance will use its best efforts to list
the Junior Subordinated Debentures on the NYSE or such other stock exchanges
or other organizations, if any, on which the Trust Securities are then listed.
There can be no assurance as to the market price of the Junior Subordinated
Debentures that may be distributed to the holders of the Trust Securities.
    
INDENTURE EVENTS OF DEFAULT
 
  The Indenture provides that any one or more of the following described
events with respect to a series of Indenture Securities that has occurred and
is continuing constitutes an "Event of Default" with respect to such series of
Indenture Securities:
 
    (i) failure for 60 days to pay any interest or similar payment on such
  series of Indenture Securities when due and payable (subject to Yorkshire
  Finance's right to defer such payment); or
 
    (ii) failure to pay principal of or premium, if any, on such series of
  Indenture Securities when due and payable; or
 
    (iii) failure to perform, or breach of, any covenant or warranty of
  Yorkshire Finance or Yorkshire Group contained in the Indenture for 60 days
  after written notice to Yorkshire Finance or Yorkshire Group from the
  Indenture Trustee or to Yorkshire Finance or Yorkshire Group and the
  Indenture Trustee by the holders of at least 33% in aggregate principal
  amount of such series of outstanding Indenture Securities as provided in
  the Indenture; or
 
    (iv) certain events in bankruptcy, insolvency or reorganization of
  Yorkshire Finance or Yorkshire Group; or
 
 
                                      91
<PAGE>
 
    (v) the Debentures Guarantee shall be held in a judicial proceeding to be
  unenforceable or invalid or shall cease for any reason to be in full force
  and effect; or
 
    (vi) any other Event of Default specified with respect to such series of
  Indenture Securities.
 
  If an Event of Default due to the default in payment of principal of, or
interest or similar payment on, any series of Indenture Securities or due to
the default in the performance or breach of any other covenant or warranty of
Yorkshire Finance or Yorkshire Group applicable to the Indenture Securities of
such series but not applicable to all series occurs and is continuing, then
either the Indenture Trustee or the holders of not less than 33% in aggregate
principal amount of the outstanding Indenture Securities of such series may
declare the principal of all of the Indenture Securities of such series and
interest or other amounts accrued or accumulated thereon to be due and payable
immediately (subject to the subordination provisions of the Indenture) and, in
the case of the Junior Subordinated Debentures, should the Indenture Trustee
or such holders of such Junior Subordinated Debentures fail to make such
declaration, the holders of at least 33% in aggregate Liquidation Amount of
the Trust Securities shall have such right. If an Event of Default due to the
default in the performance of any covenants or agreements in the Indenture
applicable to all outstanding Indenture Securities or due to certain events of
bankruptcy, insolvency or reorganization of Yorkshire Finance has occurred and
is continuing, either the Indenture Trustee or the holders of not less than
33% in aggregate principal amount of all outstanding Indenture Securities (or
Trust Securities, as described above), considered as one class, and not the
holders of the Indenture Securities (or Trust Securities) of any one of such
series, may make such declaration of acceleration (subject to the
subordination provisions of the Indenture).
 
  At any time after such a declaration of acceleration with respect to the
Indenture Securities of any series has been made and before a judgment or
decree for payment of the money due has been obtained, the Event or Events of
Default giving rise to such declaration of acceleration will, without further
act, be deemed to have been waived, and such declaration and its consequences
will, without further act, be deemed to have been rescinded and annulled, if
 
    (a) Yorkshire Finance or Yorkshire Group has paid or deposited with the
  Indenture Trustee a sum sufficient to pay
 
      (1) all overdue interest and similar payments on all Indenture
    Securities of such series;
 
      (2) the principal of and premium, if any, on any Indenture Securities
    of such series which have become due otherwise than by such declaration
    of acceleration and interest or other amounts thereon at the rate or
    rates prescribed therefor in such Indenture Securities;
 
      (3) interest upon overdue interest or other amounts at the rate or
    rates prescribed therefor in such Indenture Securities, to the extent
    that payment of such interest or other amounts is lawful; and
 
      (4) all amounts due to the Indenture Trustee under the Indenture; and
 
    (b) any other Event or Events of Default with respect to Indenture
  Securities of such series, other than the nonpayment of the principal of
  the Indenture Securities of such series which has become due solely by such
  declaration of acceleration, have been cured or waived as provided in the
  Indenture.
 
  The holders of a majority in aggregate principal amount of the Indenture
Securities of all series then outstanding may waive compliance by Yorkshire
Finance or Yorkshire Group with certain restrictive provisions of the
Indenture. The holders of a majority in principal amount of the outstanding
Indenture Securities of any series may, on behalf of the holders of all the
Indenture Securities of such series, waive any past default under the
Indenture with respect to such series, except a default in the payment of
principal of or premium, if any, or interest or other amounts (unless such
default has been cured and a sum sufficient to pay all matured installments of
interest, principal and such other amounts due otherwise than by declaration
of acceleration has been deposited with the Indenture Trustee) or a default in
respect to a covenant or provision which under the Indenture cannot be
modified or amended without the consent of the holder of each outstanding
Indenture Security of such series affected. With respect to the Junior
Subordinated Debentures, the Trust may not waive compliance by Yorkshire
Finance or Yorkshire Group with certain restrictive provisions of the
Indenture or waive any past defaults
 
                                      92
<PAGE>
 
thereunder without the consent of a majority in aggregate Liquidation Amount
of the outstanding Trust Securities.
 
  In case an Event of Default shall occur and be continuing as to the Junior
Subordinated Debentures, the Property Trustee will have the right to declare
the principal of and the interest on the Junior Subordinated Debentures and
any other amounts payable under the Indenture to be immediately due and
payable and to enforce its other rights as a creditor with respect to the
Junior Subordinated Debentures. Furthermore, a holder of Trust Securities may
institute a proceeding directly against Yorkshire Group for enforcement of
payment to such holder under the Debentures Guarantee in respect of Interest
Payments or any other payments due on the Junior Subordinated Debentures
having a principal amount equal to the aggregate Liquidation Amount of the
Trust Securities of such holder on or after the due dates specified in the
Junior Subordinated Debentures. See "Description of the Trust Securities--
Voting Rights; Amendment of Trust Agreement" and "Description of the Trust
Securities Guarantee".
 
MODIFICATION OF INDENTURE
 
  Without the consent of any holder of Indenture Securities, Yorkshire Group,
Yorkshire Finance and the Indenture Trustee may enter into one or more
supplemental indentures for any of the following purposes: (a) to evidence the
assumption by any permitted successor to Yorkshire Finance or Yorkshire Group
of the covenants of Yorkshire Finance or Yorkshire Group, respectively, in the
Indenture and in the Indenture Securities; (b) to add one or more covenants of
Yorkshire Finance or Yorkshire Group or other provisions for the benefit of
the holders of outstanding Indenture Securities or to surrender any right or
power conferred upon Yorkshire Finance or Yorkshire Group by the Indenture;
(c) to add any additional Events of Default under the Indenture with respect
to outstanding Indenture Securities; (d) to modify, eliminate or add
provisions to the Indenture to such extent as shall be necessary to ensure

publicly traded partnership taxable as a corporation for U.S. Federal income
tax purposes or (2) Yorkshire Finance or Yorkshire Group will not be required
to register as an "investment company" under the Investment Company Act; (e)
to change or eliminate any provision of the Indenture or to add any new
provision to the Indenture, provided that if such change, elimination or
addition will adversely affect the interests of the holders of any series of
Indenture Securities in any material respect, such change, elimination or
addition will become effective with respect to such series only (1) when the
consent of the holders of Indenture Securities of such series has been
obtained in accordance with the Indenture, or (2) when no Indenture Securities
of such series remain outstanding under the Indenture; (f) to provide
collateral security for the Indenture Securities; (g) to establish the form or
terms of Indenture Securities of any other series as permitted by the
Indenture; (h) to provide for the authentication and delivery of bearer
securities and coupons appertaining thereto representing interest, if any,
thereon and for the procedures for the registration, exchange and replacement
thereof and for the giving of notice to, and the solicitation of the vote or
consent of, the holders thereof, and for any and all other matters incidental
thereto; (i) to evidence and provide for the acceptance of appointment of a
separate or successor Indenture Trustee under the Indenture with respect to
the Indenture Securities of one or more series and to add to or change any of
the provisions of the Indenture as shall be necessary to provide for or to
facilitate the administration of the trusts under the Indenture by more than
one trustee; (j) to provide for the procedures required to permit the
utilization of a noncertificated system of registration for the Indenture
Securities of all or any series; (k) to change any place where (1) the
principal of and premium, if any, and interest or other payments, if any, on
all or any series of Indenture Securities shall be payable, (2) all or any
series of Indenture Securities may be surrendered for registration of transfer
or exchange and (3) notices and demands to or upon Yorkshire Finance or
Yorkshire Group in respect to Indenture Securities and the Indenture may be
served; or (l) to cure any ambiguity or inconsistency or to add or change any
other provisions with respect to matters and questions arising under the
Indenture, provided that, except in the case of clause (d) above, such changes
or additions shall not adversely affect the interests of the holders of
Indenture Securities of any series in any material respect.
 
  The Indenture contains provisions permitting Yorkshire Finance and Yorkshire
Group, with the consent of the holders of a majority in principal amount of
each outstanding series of Indenture Securities affected, to modify the
Indenture in a manner affecting the rights of the holders of such series of
the Indenture Securities;
 
                                      93
<PAGE>
 
provided, that no such modification may (i) change the maturity, if any, of
any series of Indenture Securities, or reduce the principal amount thereof, or
reduce the rate or extend the time of payment of interest thereon (except such
extension as is contemplated thereby), (ii) reduce the percentage of principal
amount of Indenture Securities of any series, the holders of which are
required to consent to any such modification of the Indenture, (iii) reduce
any amount payable under, delay or defer the required time of payment under,
or impair the right to institute suit to enforce any payment under the
Debentures Guarantee, (iv) modify the provisions of the Indenture with respect
to the subordination of the Indenture Securities or the Debentures Guarantee
or (v) modify certain of the provisions of the Indenture relating to
supplemental indentures, waivers of certain covenants and waivers of past
defaults with respect to the Indenture Securities of any series, without the
consent of the holder of each outstanding Indenture Security affected thereby,
provided, that in the case of the Junior Subordinated Debentures, so long as
any of the Trust Securities remain outstanding, no such modification may be
made that adversely affects the holders of the Trust Securities, and no
termination of the Indenture may occur, and no waiver of any Event of Default
under the Indenture or compliance with any covenant under the Indenture may be
effective, without the prior consent of the holders of a majority of the
aggregate Liquidation Amount of such Trust Securities unless and until the
principal of the Junior Subordinated Debentures and all accrued and unpaid
interest or other amounts thereon have been paid in full and certain other
conditions are satisfied.
 
  Notwithstanding the foregoing, no amendment or modification may be made to
the Indenture if such amendment or modification would cause (i) Yorkshire
Finance to be classified as an association or publicly traded partnership
taxable as a corporation for US Federal income tax purposes or (ii) Yorkshire
Finance or Yorkshire Group to be required to register as an "investment
company" under the Investment Company Act.
 
DEBENTURES GUARANTEE
 
  Pursuant to the Indenture, Yorkshire Group will irrevocably and
unconditionally guarantee the Junior Subordinated Debentures as described
under "Description of the Debentures Guarantee".
 
CERTAIN COVENANTS
 
  Each of Yorkshire Finance and Yorkshire Group will covenant in the Indenture
that it will not, directly or indirectly, (i) declare or pay any cash
dividends or distributions on, or redeem, purchase, acquire, or make a
liquidation payment with respect to, any of its capital stock, (ii) make any
payments on, or repay, repurchase or redeem, any of its debt securities
(including other Indenture Securities or other junior subordinated securities
issued by Yorkshire Finance) that rank pari passu with or junior in interest
to the Junior Subordinated Debentures or the Debentures Guarantee,
respectively, (iii) make any payments with respect to any guarantee that ranks
pari passu with or junior in interest to the Junior Subordinated Debentures or
the Debentures Guarantee, respectively, or (iv) make any payments on, or
repay, repurchase or redeem, any of its debt securities held by, make any
loans or advances to, or make any payments with respect to any guarantee of
the debt of, any affiliate, in each case other than (a) dividends or
distributions in shares of, or options, warrants or rights to subscribe for or
purchase shares of, the common stock of Yorkshire Finance or Yorkshire Group
and exchanges or conversions of common stock of one class for common stock of
another class, (b) payments by Yorkshire Group under the Trust Securities
Guarantee (or any other guarantee by Yorkshire Group with respect to any
securities of any of its direct or indirect subsidiaries, provided that the
proceeds from the issuance of such securities were used to purchase other
Indenture Securities or other junior subordinated securities issued by
Yorkshire Finance), (c) payments by Yorkshire Group under the Debentures
Guarantee, (d) any dividend or payment by Yorkshire Group which is applied,
directly or indirectly, to any Tax Payments, (e) payments by Yorkshire Group,
directly or indirectly, on the Intercompany Notes or any other promissory
notes held by Yorkshire Finance (or any other direct or indirect wholly-owned
subsidiary of Yorkshire Group) evidencing loans made with the proceeds from
the issuance by Yorkshire Finance (or any other direct or indirect wholly-
owned subsidiary of Yorkshire Group) of securities guaranteed by Yorkshire
Group or (f) the reinvestment of any proceeds received under clause (e) above
by Yorkshire Finance (or any other direct or indirect wholly-owned subsidiary
of Yorkshire Group) in additional debt securities of Yorkshire Group or any of
its other direct or indirect wholly-owned subsidiaries, if at such time (i)
there shall have occurred and be continuing a payment default (whether before
or after expiration
 
                                      94
<PAGE>
 
of any period of grace) or an Event of Default with respect to any series of
Indenture Securities, (ii) Yorkshire Group shall be in default with respect to
its payment of any obligations under the Trust Securities Guarantee or the
Debentures Guarantee or any other such guarantee as described above or (iii)
Yorkshire Finance shall have given notice of its intention to defer payment of
interest or other amounts as provided in the Indenture with respect to any
series of Indenture Securities, shall not have rescinded such notice and such
deferral shall be continuing until all deferred interest or similar payments
together with interest thereon have been paid in full.
 
  Yorkshire Finance and Yorkshire Group also will covenant that so long as any
Trust Securities remain outstanding, if the Trust shall be required to pay,
with respect to its income derived from payments of principal of or interest
on the Junior Subordinated Debentures or pursuant to the Debentures Guarantee,
any amounts for or on account of any taxes, duties, assessments or
governmental charges of whatever nature imposed by a Taxing Jurisdiction or
any other taxing authority, then, in any such case, Yorkshire Finance or
Yorkshire Group will pay as interest on the Junior Subordinated Debentures
such amounts as may be necessary in order that the net amounts received and
retained by the Trust after the payment of such taxes, duties, assessments or
governmental charges shall result in the Trust having such funds as it would
have had in the absence of the payment of such taxes, duties, assessments or
governmental charges ("Additional Interest"). Furthermore, Yorkshire Finance
and Yorkshire Group will covenant, so long as the Trust Securities remain
outstanding, to keep effective and comply with the terms and conditions of the
Demand Share Issue and Purchase Agreement, dated February 24, 1998, between
Yorkshire Finance and Yorkshire Group.
   
  Yorkshire Group will also covenant to (i) ensure that an affiliate of
Yorkshire Group will retain the Control Certificate, provided that certain
successors which are permitted pursuant to the Trust Agreement may succeed to
the ownership of the Control Certificate and (ii) use its reasonable efforts,
consistent with the terms and provisions of the Trust Agreement, to cause (a)
the Trust not to be classified as anything other than a grantor trust for US
Federal income tax purposes, (b) the Trust to remain a Transparent Trust and
not to be treated as a company for purposes of UK tax law, (c) each of
Yorkshire Group, Yorkshire Finance and the Trust not to be required to
register as an "investment company" under the Investment Company Act, (d)
Yorkshire Finance to not be classified as an association or a publicly traded
partnership taxable as a corporation for US Federal income tax purposes and
(e) Yorkshire Finance not, at any time, to be engaged in a US trade or
business for US Federal income tax purposes. Furthermore, Yorkshire Group and
Yorkshire Finance will covenant to treat the Junior Subordinated Debentures as
indebtedness of Yorkshire Finance for all US Federal income tax purposes.     
 
CONSOLIDATION, MERGER, SALE OF ASSETS AND OTHER TRANSACTIONS
 
  The Indenture provides that Yorkshire Group shall not consolidate with or
merge into any other corporation or convey, transfer or lease its properties
and assets substantially as an entirety to any person, unless (i) in case
Yorkshire Group consolidates with or merges into another corporation or
conveys or transfers its properties and assets substantially as an entirety to
any person, the successor corporation expressly assumes the obligations of
Yorkshire Group under the Debentures Guarantee; (ii) immediately after giving
effect thereto, no Event of Default under the Indenture, and no event which,
after notice or lapse of time or both, would become an Event of Default under
the Indenture, shall have occurred and be continuing; and (iii) certain other
conditions as prescribed in the Indenture are met.
 
  Yorkshire Finance may not consolidate, amalgamate, merge with or into, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to, any corporation or other entity, except as
described below. Yorkshire Finance may, without the consent of the holders of
the Junior Subordinated Debentures, consolidate, amalgamate, merge with or
into, or be replaced by a limited partnership, limited liability company or
trust organized under the laws of any state of the US; provided, that (i) such
successor entity either (a) expressly assumes all of the obligations of
Yorkshire Finance under the Junior Subordinated Debentures or (b) substitutes
for the Junior Subordinated Debentures other securities having substantially
the same terms as the Junior Subordinated Debentures (the "Successor
Debentures"), so long as the Successor Debentures are not junior to any other
equity securities of the successor entity with respect to participation in the
profits and distributions, and in the assets, of the successor entity, (ii) if
the Junior Subordinated Debentures are then so
 
                                      95
<PAGE>
 
   
listed, the Junior Subordinated Debentures continue to be listed, or any
Successor Debentures are or will be listed upon notification of issuance, on
any national securities exchange or with another organization on which the
Junior Subordinated Debentures are then listed or quoted, (iii) such merger,
consolidation, amalgamation or replacement does not cause the Trust Securities
(or, in the event that the Trust is liquidated, the Junior Subordinated
Debentures (including any Successor Debentures)) to be downgraded by any
nationally recognized statistical securities rating organization, (iv) such
merger, consolidation, amalgamation or replacement does not adversely affect
the powers, preferences and other special rights of the holders of the Trust
Securities or Junior Subordinated Debentures (including any Successor
Debentures) in any material respect (other than, in the case of Junior
Subordinated Debentures or Successor Debentures, with respect to any dilution
of the holders' interest in the new resulting entity), (v) such successor
entity has a purpose substantially identical to that of Yorkshire Finance,
(vi) Yorkshire Group guarantees the obligations of such successor entity under
the Successor Debentures to the same extent as provided by the Debentures
Guarantee and (vii) prior to such merger, consolidation, amalgamation or
replacement, Yorkshire Group and Yorkshire Finance have received an Opinion of
Counsel experienced in such matters to the effect that: (A) such successor
entity will be treated as a partnership and not as an association or publicly
traded partnership taxable as a corporation for US Federal income tax
purposes, (B) such merger, consolidation, amalgamation or replacement will not
adversely affect the limited liability of the holders of the Junior
Subordinated Debentures (or the Successor Debentures), (C) following such
merger, consolidation, amalgamation or replacement, neither Yorkshire Group,
Yorkshire Finance nor such successor entity will be required to register as an
"investment company" under the Investment Company Act and (D) such merger,
consolidation, amalgamation or replacement would not cause the Trust to be
classified as (x) other than as a grantor trust for US Federal income tax
purposes and (y) other than as a Transparent Trust for purposes of UK tax law.
    
  In the event that any such successor entity is organized under the laws of a
country located outside of the Taxing Jurisdiction and withholding or
deduction is required by law 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 such country in which the
successor entity is organized or by or within any political subdivision
thereof or any authority therein or thereof having power to tax, the successor
entity shall pay to the relevant holder of the Global Debentures or to the
relevant holders of the Definitive Registered Debentures or to the relevant
holder or holders of the Successor Debentures, as the case may be, such
additional amounts, under the same circumstances and subject to the same
limitations as are specified for "Gross-Up Taxes", as is set forth under "--
Additional Amounts" above, but substituting for the applicable Taxing
Jurisdiction in each place the name of the country under the laws of which
such successor entity is organized. In addition, such successor entity shall
be entitled to effect an optional tax redemption of the Junior Subordinated
Debentures under the same circumstances and subject to the same limitations as
are set forth under "--Optional Tax Redemption" above, but substituting for
the applicable Taxing Jurisdiction in each place the name of the country under
the laws of which such successor entity is organized.
 
  The general provisions of the Indenture do not afford holders of the Junior
Subordinated Debentures protection in the event of a highly leveraged
transaction, a change in control or other transaction involving Yorkshire
Finance or Yorkshire Group that may adversely affect holders of the Junior
Subordinated Debentures.
 
SATISFACTION AND DISCHARGE
 
  The principal amount of Junior Subordinated Debentures will be deemed to
have been paid for purposes of the Indenture and the entire indebtedness of
Yorkshire Finance in respect thereof will be deemed to have been satisfied and
discharged, if there shall have been irrevocably deposited with the Indenture
Trustee or any Paying Agent, in trust: (a) money in an amount which will be
sufficient, or (b) Government Obligations (as defined herein), which do not
contain provisions permitting the redemption or other prepayment thereof at
the option of the issuer thereof, the principal of and the interest on which
when due, without any regard to reinvestment thereof, will provide moneys
which, together with the money, if any, deposited with or held by the
Indenture Trustee, will be sufficient, or (c) a combination of (a) and (b)
which will be sufficient, to pay when due the principal of and premium, if
any, or interest or other amounts, if any, due and to become due on the Junior
 
                                      96
<PAGE>
 
Subordinated Debentures (including any Additional Amounts then known) that are
outstanding. For this purpose, Government Obligations include direct
obligations of, or obligations unconditionally guaranteed by, the US entitled
to the benefit of the full faith and credit thereof and certificates,
depository receipts or other instruments which evidence a direct ownership
interest in such obligations or in any specific interest or principal payments
due in respect thereof.
 
SUBORDINATION
 
  In the Indenture, Yorkshire Finance has covenanted and agreed that any
Indenture Securities issued thereunder will be subordinate and junior in right
of payment to all Senior Debt of Yorkshire Finance to the extent provided in
the Indenture. Upon any payment or distribution of assets to creditors upon
any liquidation, dissolution, winding-up, reorganization, assignment for the
benefit of creditors, marshaling of assets or any bankruptcy, insolvency, debt
restructuring or similar proceedings in connection with any insolvency or
bankruptcy proceeding of Yorkshire Finance, the holders of Senior Debt of
Yorkshire Finance will first be entitled to receive payment in full of
principal of, premium, if any, and interest, if any, on such Senior Debt of
Yorkshire Finance before the holders of Indenture Securities will be entitled
to receive or retain any payment in respect of the principal of, premium, if
any, or interest or other amounts, if any, on the Indenture Securities.
 
  In the event of the declaration of acceleration of any Indenture Securities,
the holders of all Senior Debt of Yorkshire Finance outstanding at the time of
such declaration will be entitled to receive payment in full of all amounts
due thereon (including any amounts due upon such declaration) before the
holders of Indenture Securities will be entitled to receive any payment upon
the principal of, premium, if any, or interest, if any, on the Indenture
Securities.
 
  No payments on account of principal, premium, if any, or interest or other
amounts, if any, in respect of any Indenture Securities may be made if there
shall have occurred and be continuing a default in any payment with respect to
Senior Debt of Yorkshire Finance or an event of default remaining uncured with
respect to any Senior Debt resulting in the acceleration of the maturity
thereof.
 
  The term "Senior Debt" means, with respect to any person, (i) any payment
due in respect of indebtedness of such person, whether outstanding at the date
of execution of the Indenture or thereafter incurred, created or assumed, (a)
in respect of money borrowed (including any financial derivative, hedging or
futures contract or similar instrument) and (b) evidenced by securities,
debentures, bonds, notes or other similar instruments issued by such person
that, by their terms, are senior or senior subordinated debt securities; (ii)
all capital lease obligations; (iii) all obligations issued or assumed as the
deferred purchase price of property, all conditional sale obligations and all
obligations of such person under any title retention agreement (but excluding
trade accounts payable arising in the ordinary course of business and long-
term purchase obligations); (iv) all obligations for the reimbursement of any
letter of credit, banker's acceptance, security purchase facility or similar
credit transaction; (v) all obligations of the type referred to in clauses (i)
through (iv) above of other persons the payment of which such person is
responsible or liable as obligor, guarantor or otherwise; and (vi) all
obligations of the type referred to in clauses (i) through (v) above of other
persons secured by any lien on any property or asset of such person (whether
or not such obligation is assumed by such person); provided, however, that
Senior Debt shall not include (1) any such indebtedness that is by its terms
subordinated to or pari passu with the Indenture Securities and (2) any
unsecured indebtedness between or among such person and its affiliates. Such
Senior Debt shall continue to be Senior Debt and be entitled to the benefits
of the subordination provisions contained in the Indenture irrespective of any
amendment, modification or waiver of any term of such Senior Debt.
 
  The Indenture places no limitation on the amount of additional Senior Debt
that may be incurred by Yorkshire Finance or Yorkshire Group. Yorkshire
Finance and Yorkshire Group expect from time to time to incur additional
indebtedness constituting Senior Debt.
 
FORM, BOOK-ENTRY PROCEDURES AND TRANSFER
 
 General
 
  The Junior Subordinated Debentures will be issued initially only as a Global
Debenture in bearer form (the "Global Debenture") and will be payable only in
US dollars. Title to such Global Debentures will pass by
 
                                      97
<PAGE>
 
delivery. The Global Debentures will be deposited on issue with The Bank of
New York in New York, New York, as book-entry depositary (the "Book-Entry
Depositary"), which will hold the Global Debentures for the benefit of the
Trust pursuant to the terms of the deposit agreement (the "Deposit Agreement")
dated as of May  , 1998 among Yorkshire Finance, the Book-Entry Depositary and
the holders and beneficial owners from time to time of interests in the Book-
Entry Interests. Pursuant to the Deposit Agreement, the Book-Entry Depositary
will issue one or more certificateless depository interests (the "Book-Entry
Interests"), which together will represent a 100% beneficial interest in the
Global Debentures. Such Book-Entry Interests will initially be issued to the
Property Trustee.
 
  If Book-Entry Interests are distributed to holders of Trust Securities in
liquidation of such holders' interests in the Trust, the Global Debentures
held by the Book-Entry Depositary and representing all of the Junior
Subordinated Debentures will cease to be held for the benefit of the Trust and
will, for all purposes under the Indenture and the Deposit Agreement, be held
by the Book-Entry Depositary for the benefit of DTC and its Participants, and
all of the Book-Entry Interests in the Global Debentures will be transferred
by the Property Trustee to DTC, which will operate a book-entry system for
interests in the Book-Entry Interests in global form (the "Global Book-Entry
Interests"). DTC will initially credit Direct Participants holding Trust
Securities with interests in the Global Book-Entry Interests (pro rata to
their holding of Trust Securities) registered in the name of DTC or its
nominee. Unless and until the Global Debentures are exchanged in whole for
Definitive Registered Debentures, Global Book-Entry Interests 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. For a description of DTC
and its book-entry system, see "Description of the Trust Securities--Book
Entry Issuance". As of the date of this Prospectus, the description herein of
DTC's book-entry system and DTC's practices as they relate to purchases,
transfers, notices and payments with respect to the Trust Securities will
apply in all material respects to any Global Book-Entry Interests registered
in the name of and held by DTC or its nominee. Yorkshire Finance may appoint a
successor to DTC or any successor depositary in the event DTC or such
successor depositary is unable or unwilling to continue as depositary for the
Global Book-Entry Interests.
 
  The laws of some jurisdictions require that certain purchasers of securities
take physical delivery of such securities in definitive form. Such laws may
impair the ability to transfer beneficial interests in such Global Book Entry
Interests.
 
  So long as the Book-Entry Depositary, or its nominee, is the holder of the
Global Debentures, the Book-Entry Depositary or such nominee, as the case may
be, will be considered the sole holder of the Global Debentures (and the
Junior Subordinated Debentures) for all purposes under the Indenture. Except
as set forth below with respect to the issuance of Definitive Registered
Perpetual Securities, if the Junior Subordinated Debentures (represented by
Global Book-Entry Interests) are held through the facilities of DTC, Direct
Participants or Indirect Participants will not be entitled to have Junior
Subordinated Debentures registered in their names, will not receive or be
entitled to receive physical delivery of Junior Subordinated Debentures in
definitive bearer or registered form and will not be considered the owners or
holders thereof under the Indenture or the Deposit Agreement. Accordingly, if
the Junior Subordinated Debentures (represented by Global Book-Entry
Interests) are held through the facilities of DTC, each person owning an
interest in the Global Book-Entry Interests must rely on the procedures of the
Book-Entry Depositary and DTC and, if such person is not a Direct Participant
in DTC, on the procedures of the Direct Participant through which such person
owns its interest, to exercise any rights and obligations of a holder under
the Indenture or the Deposit Agreement.
 
  In addition to a Paying Agent in the Borough of Manhattan, The City of New
York, Yorkshire Finance will, so long as Junior Subordinated Debentures are
listed on the Luxembourg Stock Exchange and the rules of such stock exchange
so require, maintain a Paying Agent in Luxembourg.
 
  Neither Yorkshire Finance, Yorkshire Group nor any agent of Yorkshire
Finance or Yorkshire Group will have any responsibility or liability for any
aspect relating to payments made or to be made by the Book-Entry Depositary to
the persons entitled thereto in respect of the Junior Subordinated Debentures
or the Book-Entry Interests. None of Yorkshire Finance, Yorkshire Group, the
Indenture Trustee, the Book-Entry Depositary or any
 
                                      98
<PAGE>
 
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
Direct Participant's or Indirect Participant's ownership of an interest in the
Global Book-Entry Interests or for maintaining, supervising or reviewing any
records relating to a Direct Participant's or Indirect Participant's interests
in the Global Book-Entry Interests.
 
 Payments on the Junior Subordinated Debentures
 
  Payments of any amounts in respect of the Global Debenture will be made
through a Paying Agent to the Book-Entry Depositary, as the holder thereof.
Such payments shall be considered paid on the date they are due if the Paying
Agent holds at 11:00 a.m. New York City time on that date money deposited by
or on behalf of Yorkshire Group or Yorkshire Finance in immediately available
funds, designated for and sufficient to pay the amount due in full. The Book-
Entry Depositary will pay an amount equal to each such payment to the Property
Trustee as the initial holder of the Book-Entry Interests, which will
distribute such payments to DTC. If the Global Book-Entry Interests
representing the Junior Subordinated Debentures are held through the
facilities of DTC, such payments will be made by the Book-Entry Depository to
DTC, as holder of the Global Book-Entry Interests, which will distribute such
payments to its Direct Participants.
 
  If any Definitive Registered Debentures have been issued, the interest
payable on such Definitive Registered Debenture other than at maturity will be
paid to the holder in whose name such Definitive Registered Debenture is
registered at the close of business on the fifteenth day (whether or not a
Business Day) immediately preceding the relevant Interest Payment Date (each a
"Record Date"). The principal amount of a Definitive Registered Debenture will
be payable to the person in whose name such Definitive Registered Debenture is
registered at the close of business on the immediately preceding Record Date
upon surrendering such Definitive Registered Debenture at the Indenture
Trustee's office in New York City. Interest payable at maturity will be
payable to the person to whom principal is payable.
 
  If any Definitive Registered Debentures have been issued, Interest Payments
on such Definitive Registered Debentures 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. Interest Payments on the Definitive
Registered Debentures may also be made, in the case of a holder of at least US
$1,000,000 aggregate principal amount of Junior Subordinated Debentures by
wire transfer to a US Dollar account maintained by the payee with a bank in
the US; provided that such holder elects payment by wire transfer by giving
written notice to the Indenture 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 Indenture Trustee may
accept in its discretion).
 
  Any monies paid by Yorkshire Finance or Yorkshire Group to the Indenture
Trustee or any Paying Agent, or held by Yorkshire Finance or Yorkshire Group
in trust, or the payments of the principal of or any interest or Additional
Amounts on any Junior Subordinated Debentures and remaining unclaimed at the
end of two years after such principal, interest or Additional Amounts become
due and payable will be paid to the US Affiliates, or released from the trust,
upon its written request, and upon such payment or release all liability of
Yorkshire Finance, Yorkshire Group, the Indenture Trustee and such Paying
Agent with respect thereto will cease.
 
  All payments to the Book-Entry Depositary in respect of the Global
Debenture, and all payments to the holders of the Definitive Registered
Debentures, if issued, will be made without deduction or withholding for any
Gross-Up Taxes or other governmental charges, or if any such deduction or
withholding is required to be made under the provisions of any applicable 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 Debenture or of any Definitive
Registered Debenture, after such deduction or withholding, will equal the
amounts that such holder would have otherwise received in respect of the
Global Debentures or of such Definitive Registered Debentures absent such
deduction or withholding. If Definitive Registered Debentures are issued
pursuant to an Optional Definitive Security Request, neither Yorkshire Finance
nor Yorkshire Group will be obligated to pay Additional Amounts in respect of
such Definitive Registered Debentures.

<PAGE>
 
  If the due date for any interest in respect of the Junior Subordinated
Debentures 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.
 
 Redemption
 
  In the event the Global Debenture (or a portion thereof) is redeemed, the
Book-Entry Depositary will deliver all amounts received by it in respect to
the redemption of the Global Debenture to the persons entitled thereto and (in
the case of redemption in full) surrender the Global Debenture to the
Indenture Trustee for cancellation. The redemption price payable in connection
with the redemption of interests in a Book-Entry Interest will be equal to the
amount received by the Book-Entry Depositary in connection with the redemption
of the Global Debentures (or a portion thereof). For any redemption of the
Global Debenture in part, if the Junior Subordinated Debentures are held
through the facilities of DTC, selection of interests in the related Global
Book-Entry Interest to be redeemed will be made in accordance with the
procedures of DTC. Once redeemed in part, a new Global Debenture in the
principal amount equal to the unredeemed portion thereof will be issued and
delivered to the Book-Entry Depositary.
 
 Action by Holders of Junior Subordinated Debentures
 
  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 Junior Subordinated Debentures, the Book-Entry Depositary will mail
to the Property Trustee (or, if the Global Book-Entry Interests representing
the Junior Subordinated Debentures are then held through the facilities of
DTC, 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 the Property Trustee (or DTC, as applicable) will be entitled, subject to
the provisions of the Indenture, to instruct the Book-Entry Depositary as to
the consent, waiver or other action, if any, pertaining to the Junior
Subordinated Debentures and (c) a statement as to the manner in which such
instructions may be given. Upon the written request of the Property Trustee
(or DTC, as applicable), 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 Junior Subordinated Debentures in accordance
with any instructions set forth in such request. DTC is expected to follow
procedures described under "Description of the Trust Securities--Book-Entry
Issuance" with respect to soliciting instructions from 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
or the Indenture.
 
 Meetings of Holders of Junior Subordinated Debentures
 
  A meeting of the holders of Junior Subordinated Debentures may be called at
any time from time to time pursuant to the Indenture to make, give or take any
request, demand, authorization, direction, notice, consent, waiver or other
action provided by the Indenture to be made given or taken by holders of the
Junior Subordinated Debentures.
 
  To be entitled to vote at any meeting of holders of Junior Subordinated
Debentures, a person shall be (a) a holder of Junior Subordinated Debentures
or (b) a person appointed by an instrument in writing as proxy for a holder or
holders of Junior Subordinated Debentures by such holder or holders. The only
persons who shall be entitled to attend any meeting of holders of Junior
Subordinated Debentures shall be the persons so entitled to vote at such
meeting and their counsel, any representatives of the Indenture Trustee and
its counsel, and any representatives of Yorkshire Finance and its counsel.
 
  At any meeting of holders of Junior Subordinated Debentures, the persons
holding or representing Junior Subordinated Debentures in an aggregate
principal amount sufficient under the appropriate provision of the Indenture
to take action upon the business for the transaction of which such meeting was
called shall constitute a quorum. No action at a meeting of holders shall be
effective unless approved by persons holding or representing Junior
Subordinated Debentures in the aggregate principal amount required by the
provision of the Indenture pursuant to which such action is being taken. At
any meeting of holders, each holder or proxy shall be entitled to one vote for
each $1 principal amount of outstanding Junior Subordinated Debentures held or
represented.
 
                                      100
<PAGE>
 
  Until such time as written instruments shall have been delivered to the
Indenture Trustee evidencing the taking of any action at a meeting of holders
by the holders of the percentage in aggregate principal amount of the Junior
Subordinated Debentures specified in the Indenture in connection with such
action, any holder of a Junior Subordinated Debenture the serial number of
which is included in the Junior Subordinated Debentures the holders of which
have consented to such action may, by filing written notice with the Indenture
Trustee at its principal corporate trust office and upon proof of holding as
provided in the Indenture, revoke such consent so far as concerns such Junior
Subordinated Debentures. Except as aforesaid any such consent given by the
holder of any Junior Subordinated Debentures shall be conclusive and binding
upon such holder and upon all future holders and owners of such Junior
Subordinated Debentures and of any securities issued in exchange therefor, in
lieu thereof or upon transfer thereof, irrespective of whether or not any
notation in regard thereto is made upon such securities. Any action taken by
the holders of the percentage in aggregate principal amount of the holders
specified in the Indenture in connection with such action shall be
conclusively binding upon Yorkshire Finance, the Indenture Trustee and the
holders of all the Junior Subordinated Debentures.
 
 Reports and Notices
 
  So long as the Junior Subordinated Debentures are listed on the Luxembourg
Stock Exchange and the rules of such Stock Exchange so require, notice to
holders of the Junior Subordinated Debentures will be published in a leading
newspaper having general circulation in Luxembourg (which is expected to be
the Luxemburger Wort) in addition to notifying the Book-Entry Depositary. If
any Junior Subordinated Debentures have been distributed to holders of Trust
Securities, the Book-Entry Depositary will immediately send to DTC a copy of
any notices, reports and other communications received by it relating to
Yorkshire Finance, Yorkshire Group or the Junior Subordinated Debentures. In
the case of Definitive Registered Debentures, all notices regarding the Junior
Subordinated Debentures will, in addition to publication as referred to above,
be mailed to holders by first-class mail at their respective addresses as they
appear on the registration books of the registrar.
 
 Amendment and Termination of the Deposit Agreement
 
  The Deposit Agreement may be amended by agreement between Yorkshire Finance
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 the Deposit Agreement, (ii) to
add to the covenants and agreements of Yorkshire Finance 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 Securities
Act, the Exchange Act, the 1939 Act or the Investment Company Act, or any
other applicable securities laws, (v) to modify the Deposit Agreement in
connection with an amendment of the Indenture that does not require the
consent of the holders of Junior Subordinated Debentures 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 Yorkshire Finance, is not materially adverse to the Property Trustee or DTC
(if any Junior Subordinated Debentures (represented by Global Book-Entry
Interests) are then held through the facilities of DTC) or the beneficial
owners of the interests in the Book-Entry Interests. Except as provided in the
preceding sentence, no amendment that materially adversely affects any holder
or beneficial owner of an interest in the Book-Entry Interests may be made to
the Deposit Agreement without the consent of such holder or beneficial owner.
 
  If Definitive Registered Debentures are issued by Yorkshire Finance in
exchange for the entire Global Debenture, the Book-Entry Depositary, as holder
of the Global Debenture, will surrender the Global Debenture against receipt
of the Definitive Registered Debentures and distribute the Definitive
Registered Debentures to the holders of Book-Entry Interests (or such other
persons as the Book-Entry Depositary becomes aware are entitled thereto),
whereupon the Deposit Agreement will terminate. The Deposit Agreement may also
be terminated upon the resignation of the Book-Entry Depositary if no
successor has been appointed within 120 days.
 
 Resignation of Book-Entry Depositary
 
  The Book-Entry Depositary may at any time resign as Book-Entry Depositary
with respect to the Global Debenture. If a successor depository meeting the
requirements specified in the Deposit Agreement has agreed to
 
                                      101
<PAGE>
 
enter into arrangements with the same effect as the Deposit Agreement, the
Book-Entry Depositary shall deliver the Global Debenture to that successor. If
no such successor has so agreed within 120 days, the terms of the Deposit
Agreement provide that the Property Trustee or DTC (if any Junior Subordinated
Debentures (represented by Global Book-Entry Interests) are held through the
facilities of DTC) may request Yorkshire Finance to issue Definitive
Registered Debentures with respect to the Global Debenture. On receipt of such
Definitive Registered Debentures, the Book-Entry Depositary will surrender the
Global Debenture and distribute such Definitive Registered Debentures to the
persons entitled thereto. The Deposit Agreement will then terminate.
 
 Obligation of Book-Entry Depositary
 
  The Book-Entry Depositary will assume no obligation or liability under the
Deposit Agreement other than to act in good faith without negligence or
willful misconduct in the performance of its duties thereunder.
 
 Definitive Registered Debentures
 
  Beneficial owners of the Book-Entry Interests shall be entitled to receive
definitive Junior Subordinated Debentures in registered form ("Definitive
Registered Debentures") only in the limited circumstances set forth in this
paragraph. The Book-Entry Depositary will promptly notify the Indenture
Trustee and request in writing that Yorkshire Finance issue and the Indenture
Trustee authenticate and deliver Definitive Registered Debentures in exchange
for the Global Debenture, as a whole but not in part, in such names and
authorized denominations as DTC shall specify, if: (i) DTC notifies Yorkshire
Finance and the Book-Entry Depositary that it is unwilling or unable to
continue to hold the Global Book-Entry Interests related to the Global
Debenture or DTC at any time ceases to be a "clearing agency" registered as
such under the Exchange Act and, in either case, a successor is not appointed
by Yorkshire Finance within 120 days; (ii) the Book-Entry Depositary notifies
Yorkshire Finance that it is unwilling or unable to continue as Book-Entry
Depositary with respect to the Global Debenture and no successor Book-Entry
Depositary is appointed within 120 days; or (iii) Yorkshire Finance, in its
sole discretion, executes and delivers to the Indenture Trustee an officers'
certificate providing that the Global Debentures of such series shall be so
exchangeable. In addition, if an Event of Default shall have occurred and be
continuing with respect to the Junior Subordinated Debentures, any beneficial
owner of interests in Book-Entry Interests in the Global Debenture shall, upon
written request, be entitled to receive Definitive Registered Debentures in
exchange for such interests (an "Optional Definitive Security Request"). In no
event will an owner of beneficial interests in the Book-Entry Interests be
entitled to receive definitive Junior Subordinated Debentures in bearer form
on account of such ownership.
 
  Definitive Registered Debentures so issued will be issued only in minimum
denominations of $25 and integral multiples thereof and will be issued in
registered form only, without coupons, and shall have the same interest rate,
terms and the same aggregate principal amount as the Global Debenture for
which they are exchanged. Such Definitive Registered Debentures shall be
registered in the name or names of such persons 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 Interests.
 
  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 DEBENTURES, SUCH PARTICIPANTS AND INDIRECT
PARTICIPANTS, AS HOLDERS OF DEFINITIVE REGISTERED DEBENTURES, WILL BECOME
SUBJECT TO UK INCOME TAX (CURRENTLY AT THE RATE OF 20%) THAT MUST BE WITHHELD
ON ANY PAYMENTS OF INTEREST ON THE JUNIOR SUBORDINATED DEBENTURES AS SET FORTH
UNDER "MATERIAL INCOME TAX CONSIDERATIONS--UK INCOME TAX CONSIDERATIONS". IF
SUCH DEFINITIVE REGISTERED DEBENTURES ARE ISSUED FOLLOWING AN EVENT OF DEFAULT
WITH RESPECT TO JUNIOR SUBORDINATED DEBENTURES PURSUANT TO THE REQUEST OF
BENEFICIAL OWNERS OF INTERESTS IN THE
 
                                      102
<PAGE>
 
BOOK-ENTRY INTERESTS IN ALL OF THE GLOBAL DEBENTURES, NEITHER YORKSHIRE
FINANCE NOR YORKSHIRE GROUP WILL BE OBLIGATED TO PAY ANY ADDITIONAL AMOUNTS IN
RESPECT OF SUCH DEFINITIVE REGISTERED DEBENTURES.
 
  However, holders of Definitive Registered Debentures may be entitled to
receive a refund of withheld amounts from the UK Inland Revenue in certain
circumstances. See "Material Income Tax Considerations--UK Tax
Considerations". In addition, if an owner of a beneficial interest in a Book-
Entry Interest receives Definitive Registered Debentures other than pursuant
to its request, such owner will be entitled to receive Additional Amounts with
respect to such Definitive Registered Debentures. See "--Additional Amounts".
 
 Transfer and Exchange of Definitive Registered Debentures
 
  In the event that Definitive Registered Debentures are issued, a holder may
transfer or exchange the Definitive Registered Debentures in accordance with
the Indenture. Yorkshire Finance and the transfer agent and registrar may
require a holder, among other things, to furnish appropriate endorsements and
transfer documents, and may require a holder to pay a sum sufficient to cover
any taxes, other governmental charges and fees required by law or permitted by
the Indenture. Yorkshire Finance is not required to issue, register the
transfer of or exchange Definitive Registered Debentures 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 as required by the Indenture and ending at
the close of business on the day of such mailing, or to register the transfer
of or exchange any Definitive Registered Debentures so selected for redemption
in whole or in part, except that Yorkshire Finance shall be required to
register the transfer of or exchange the unredeemed portion of any Definitive
Registered Debentures being redeemed in part. Upon the issuance of Definitive
Registered Debentures, holders will be able to transfer and exchange
Definitive Registered Debentures at the offices of the transfer agent and
registrar; 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 Security Register maintained by the transfer agent and
registrar.
 
GOVERNING LAW; SUBMISSION TO JURISDICTION
 
  The Indenture, the Junior Subordinated Debentures and the Debentures
Guarantee will be governed by and construed in accordance with the laws of the
State of New York. Any legal suit, action or proceeding against Yorkshire
Finance or Yorkshire Group or the properties, assets or revenues with respect
to their respective obligations, liabilities or any other matter relating to
Yorkshire Finance or Yorkshire Group arising out of or in connection with the
Indenture, a Junior Subordinated Debenture or the Debentures Guarantee may be
brought in the Supreme Court of New York, New York County or in the United
States District Court for the Southern District of New York and any appellate
court from either thereof. Yorkshire Finance and Yorkshire Group have
submitted to the non-exclusive jurisdiction of such courts for the purposes of
any such proceeding and have irrevocably waived, to the fullest extent that
they may effectively do so, any objection to the laying of venue of any such
proceeding in any such court and the defense of an inconvenient forum.
 
INFORMATION CONCERNING THE INDENTURE TRUSTEE
 
  The Indenture Trustee shall have, and shall be subject to, all the duties
and responsibilities specified with respect to an indenture trustee under the
1939 Act. Subject to such provisions, the Indenture Trustee is under no
obligation to exercise any of the powers vested in it by the Indenture at the
request of any holder of Junior Subordinated Debentures, unless offered
reasonable indemnity by such holder against the costs, expenses and
liabilities which might be incurred thereby. The Indenture Trustee is not
required to expend or risk its own funds or otherwise incur personal financial
liability in the performance of its duties if the Indenture Trustee reasonably
believes that repayment or adequate indemnity is not reasonably assured to it.

                    DESCRIPTION OF THE DEBENTURES GUARANTEE
 
  Pursuant to the Indenture, Yorkshire Group will irrevocably and
unconditionally guarantee all payments on the Junior Subordinated Debentures
when and as the same shall become due and payable, whether at maturity, upon
redemption or otherwise. The Debentures Guarantee will be a direct and
unsecured obligation of Yorkshire Group and will rank subordinate and junior
to all Senior Debt that may be issued by Yorkshire Group. As of December 31,
1997, Senior Debt of Yorkshire Group aggregated approximately (Pounds)1,034
million ($1,699 million), a portion of which will be repaid with proceeds of
this offering. Yorkshire Group is a non-operating holding company, conducting
substantially all of its business through Yorkshire and its subsidiaries.
Except to the extent that Yorkshire Group receives funds from the US Parents
in the future, Yorkshire Group will rely on dividends, indirectly, from
Yorkshire to meet its obligations for payment of its outstanding obligations,
including any payments necessary pursuant to the Debentures Guarantee, and
corporate expenses. Furthermore, Yorkshire Group's obligations under the
Debentures Guarantee will effectively be subordinated to all existing and
future indebtedness and liabilities of the subsidiaries of Yorkshire Group,
including Yorkshire. As a result, the rights of holders of the Trust
Securities in respect of claims on the assets of each of the Yorkshire Group's
subsidiaries upon any liquidation or administration are structurally
subordinated to, and therefore will be subject to the prior claims of, the
creditors of Yorkshire and its subsidiaries (including trade creditors),
except to the extent that Yorkshire Group may itself be a creditor with
recognized claims against Yorkshire and its subsidiaries. At December 31,
1997, the direct and indirect subsidiaries of Yorkshire Group had total
indebtedness (excluding indebtedness owed to Yorkshire Group) of approximately
(Pounds)476 million ($782 million) and such subsidiaries may incur additional
indebtedness in the future.
 
  During an Extension Period, Yorkshire Group's obligations to make payments
under the Debentures Guarantee will be suspended. See "Description of the
Junior Subordinated Debentures--Option to Defer Payment of Interest".
 
  Under the terms of the Indenture and the Debentures Guarantee, if the
Property Trustee fails to enforce the Trust's rights with respect to the
Debentures Guarantee, a holder of Trust Securities may institute a legal
proceeding directly against Yorkshire Group to enforce the Trust's rights with
respect to the Debentures Guarantee to the fullest extent permitted by law,
without first instituting any legal proceeding against the Property Trustee or
the Trust. Notwithstanding the foregoing, a holder of Trust Securities may
institute a legal proceeding directly against Yorkshire Group for enforcement
of payment to such holder under the Debentures Guarantee in respect of
principal of or interest on the Junior Subordinated Debentures having a
principal amount equal to the aggregate Liquidation Amount of the Trust
Securities of such holder on or after the due dates specified in the Junior
Subordinated Debentures, without first instituting any legal proceeding
against the Property Trustee or any other person.

                   RELATIONSHIP AMONG THE TRUST SECURITIES,
                      THE JUNIOR SUBORDINATED DEBENTURES,
                      THE TRUST SECURITIES GUARANTEE AND
                           THE DEBENTURES GUARANTEE
 
  As long as Interest Payments and other payments are made when due on the
Junior Subordinated Debentures, such payments will be sufficient to cover
Distributions and other payments due on the Trust Securities, primarily
because (i) the aggregate principal amount of the Junior Subordinated
Debentures will be equal to the sum of the aggregate Liquidation Amount of the
Trust Securities, (ii) the interest rate and Interest Payment Dates on the
Junior Subordinated Debentures will match the Distribution rate and
Distribution Dates and other payment dates for the Trust Securities; (iii) the
Agreement as to Expenses and Liabilities provides that the US Affiliates shall
pay for all and any costs, expenses and liabilities of the Trust (except the
obligations of the Trust to pay holders of the Trust Securities the amounts
due such holders pursuant to the terms of the Trust Securities); and (iv) the
Trust Agreement further provides that the Trust will not engage in any
activity that is not consistent with the limited purposes of the Trust.
 
  Payments of Distributions and other amounts due on the Trust Securities (to
the extent the Trust has sufficient funds available for the payment of such
Distributions) are irrevocably guaranteed by Yorkshire Group as and to the
extent set forth under "Description of the Trust Securities Guarantee". If and
to the extent that Yorkshire Finance does not make payments on the Junior
Subordinated Debentures or Yorkshire Group does not make payments pursuant to
the Debentures Guarantee, the Trust will not pay Distributions or other
amounts due on the Trust Securities. The Trust Securities Guarantee does not
cover payment of Distributions when the Trust does not have sufficient funds
available to pay such Distributions.
 
  If the Trust has sufficient funds available to make Distribution payments,
but does not make such payments and Yorkshire Group fails to make payments
under the Trust Securities Guarantee, the Trust Securities Guarantee provides
a mechanism whereby the holders of the Trust Securities may direct the
Guarantee Trustee to enforce its rights thereunder. In addition, any holder of
Trust Securities may institute a legal proceeding directly against Yorkshire
Group to enforce the Guarantee Trustee's rights under the Trust Securities
Guarantee without first instituting a legal proceeding against the Guarantee
Trustee or any other person or entity.
 
  Furthermore, if Yorkshire Finance fails to make Interest Payments or other
payments which are due on the Junior Subordinated Debentures or Yorkshire
Group does not make payments which are due pursuant to the Debentures
Guarantee, the Trust Agreement provides a mechanism whereby the holders of the
Trust Securities may direct the Property Trustee to enforce its rights under
the Junior Subordinated Debentures and the Debentures Guarantee, including
proceeding directly against Yorkshire Finance to enforce the Junior
Subordinated Debentures and proceeding directly against Yorkshire Group to
enforce the Debentures Guarantee. If the Property Trustee fails to enforce its
rights under the Debentures Guarantee, to the fullest extent permitted by
applicable law, any holder of Trust Securities may institute a legal
proceeding directly against Yorkshire Group to enforce the Property Trustee's
rights under the Debentures Guarantee without first instituting any legal
proceeding against the Property Trustee or any other person or entity.
Notwithstanding the foregoing, a holder of Trust Securities may institute a
legal proceeding directly against Yorkshire Group, without first instituting a
legal proceeding against the Property Trustee or any other person or entity,
for enforcement of payment to such holder under the Debentures Guarantee in
respect of Interest Payments or any other payments due on the Junior
Subordinated Debentures having an aggregate principal amount equal to the
aggregate Liquidation Amount of the Trust Securities of such holder on or
after the due dates specified in the Junior Subordinated Debentures.
 
  The Debentures Guarantee, the Trust Securities Guarantee, the Indenture, the
Junior Subordinated Debentures, the Trust Agreement and the Agreement as to
Expenses and Liabilities, when taken together, effectively provide a full and
unconditional guarantee, on a subordinated basis, of the Trust's obligations
under the Trust Securities. No single document standing alone or operating in
conjunction with fewer than all of the
 
                                      105
<PAGE>
 
other documents constitutes such guarantee. It is only the combined operation
of these documents that has the effect of providing a full, irrevocable and
unconditional guarantee of the Trust's obligations under the Trust Securities.
 
  Notwithstanding anything to the contrary in the Indenture and the Debentures
Guarantee, Yorkshire Group has the right to set-off any payment it is
otherwise required to make under the Debentures Guarantee with and to the
extent Yorkshire Finance has theretofore made, or is concurrently on the date
of such payment making, a payment under the Indenture.
 
  Upon any voluntary or involuntary dissolution, winding-up or liquidation of
the Trust not involving the distribution of the Junior Subordinated
Debentures, after satisfaction of creditors of the Trust, if any, as provided
by the Delaware Act, the holders of Trust Securities will be entitled to
receive, out of assets held by the Trust, the Liquidation Distribution in
cash. See "Description of the Trust Securities--Liquidation Distribution upon
Dissolution". Upon any voluntary or involuntary liquidation or bankruptcy of
Yorkshire Finance, the Property Trustee, as beneficial owner of the Junior
Subordinated Debentures, would be a subordinated creditor of Yorkshire
Finance, subordinated in right of payment to all Senior Debt, but entitled to
receive all payments in full due on the Junior Subordinated Debentures, before
any stockholders of Yorkshire Finance receive payments or distributions.
Because Yorkshire Group is the guarantor under the Debentures Guarantee and
the Trust Securities Guarantee, the positions of a holder of Trust Securities
and a holder of Junior Subordinated Debentures relative to other creditors and
to stockholders of Yorkshire Group in the event of liquidation or bankruptcy
of Yorkshire Group would be substantially the same.
 
  A default or event of default under any Senior Debt would not constitute a
default or Event of Default with respect to the Junior Subordinated
Debentures. However, in the event of payment defaults under, or acceleration
of, Senior Debt, the subordination provisions of the Indenture provide that no
payments may be made in respect of the Junior Subordinated Debentures until
such Senior Debt has been paid in full or any payment default thereunder has
been cured or waived. Failure to make required payments on any Junior
Subordinated Debentures would constitute an Event of Default under the
Indenture.

                      MATERIAL INCOME TAX CONSIDERATIONS
 
  PROSPECTIVE PURCHASERS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO
THEIR PARTICULAR CIRCUMSTANCES AND THE EFFECT OF STATE, LOCAL OR FOREIGN LAWS,
INCLUDING UK TAX LAWS, TO WHICH THEY MAY BE SUBJECT.
 
UK TAX CONSIDERATIONS
 
  The comments below are based on UK law and UK Inland Revenue practice as of
the date of this Prospectus and represent the opinion of Allen & Overy, UK
counsel to Yorkshire Group, Yorkshire Finance and the Trust, so far as such
comments relate to matters of law or legal conclusions. They relate only to
holders of Junior Subordinated Debentures who are the absolute beneficial
owners thereof and related interest and may not apply to certain classes of
persons, including persons who do not hold such securities as capital assets
and special classes of investors such as dealers in securities. The UK
inheritance tax is not discussed. The UK tax position of a holder of the Trust
Securities is not addressed because the Trust is not a UK entity and is not
intended to be resident in the UK for UK tax purposes and the Trust Securities
will not be offered to UK-resident persons. Moreover, these comments do not
address the tax position of UK-resident holders of Junior Subordinated
Debentures (or of holders of such Junior Subordinated Debentures who carry on
a trade profession or vocation in the UK through a branch or agency to which
the holding of such Junior Subordinated Debentures is attributable). Any
prospective holders of Junior Subordinated Debentures or Trust Securities who
are in any doubt as to their tax position should consult their professional
advisers.
 
 Payments on the Junior Subordinated Debentures
 
  For UK tax purposes, provided that the Junior Subordinated Debentures (i)
remain represented by the Global Debenture, (ii) are in bearer form and (iii)
continue to be listed on the Luxembourg Stock Exchange or some other stock
exchange recognized under Section 841 UK Income and Corporation Taxes Act 1988
by the UK Inland Revenue, Interest Payments by Yorkshire Finance to the Trust
or any other holder of the Junior Subordinated Debentures may be made without
withholding or deduction for or on account of UK income tax for so long as the
paying agent of Yorkshire Finance, the Book-Entry Depositary, and the Trust is
not in the UK. In the event that Yorkshire Finance becomes liable to make any
withholding or deduction in respect of Interest Payments on the Junior
Subordinated Debentures, Additional Amounts will become payable to the extent
set out above under "Description of the Junior Subordinated Debentures--
Additional Amounts".
 
  In other cases (subject to any direction to the contrary by the UK Inland
Revenue under an applicable double-taxation treaty), and in particular if
Definitive Registered Debentures are issued, Interest Payments will be made
after deduction of UK income tax (currently at the rate of 20%). A US-resident
holder of Junior Subordinated Debentures may be eligible to recover in full
any UK tax withheld from Interest Payments 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 such a US holder
in advance of an Interest Payment. If the claim is accepted by the UK Inland
Revenue, they will usually authorize subsequent payments to that US holder to
be made without withholding of UK income tax. Claims for repayment of UK tax
withheld 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 Payments relate and
must be accompanied by the original statement provided by Yorkshire Finance
when the Interest Payment was made showing the amount of UK income tax
deducted. Because a claim is not considered made until the UK tax authorities
receive the appropriate form from the Internal Revenue Service (the "IRS"),
forms should be sent to the IRS, 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.
 
  Where a person in the UK acts as a collecting agent, i.e. either:
 
    (i) acts as custodian of the Junior Subordinated Debentures and receives
  Interest Payments on the Junior Subordinated Debentures or directs that
  Interest Payments on the Junior Subordinated Debentures be paid to another
  person, or consents to such payment; or
 
                                      107
<PAGE>
 
    (ii) collects or secures payment of, arranges to secure or collect
  payment of or receives Interest Payments on, the Junior Subordinated
  Debentures for a holder (except by means of clearing a cheque or arranging
  for the clearing of a cheque),
 
the collecting agent will be required to withhold on account of UK income tax
at the lower rate (currently 20%) unless the person who is the beneficial
owner of the Junior Subordinated Debentures and beneficially entitled to the
interest is not resident in the UK, and a declaration to that effect in the
required form has been given to the collecting agent, or the Inland Revenue
has issued a notice to the collecting agent, or one of the other exceptions to
the withholding obligation applies and, in each case, the conditions imposed
by regulations which need to be satisfed for the exemption from withholding to
apply have been complied with.
 
  The above collecting agent rules apply to the Trust Securities as they apply
to the Junior Subordinated Debentures. The Trust does not intend to appoint a
UK collecting agent in respect of Interest Payments on the Junior Subordinated
Debentures. The above section may become relevant in relation to the Junior
Subordinated Debentures if they are distributed to the holders of the Trust
Securities in a liquidation of the Trust.
 
  In the event that the Junior Subordinated Debentures are distributed to the
holders of the Trust Securities in a liquidation of the Trust, holders of
Junior Subordinated Debentures in other jurisdictions may be entitled to a
refund of all or part of any UK income tax deducted or withheld or to make a
claim for interest on the Junior Subordinated Debentures to be paid without,
or subject to a reduced rate of, deduction or withholding under the provisions
of an applicable double tax treaty.
 
  A credit in respect of all or part of any UK income tax deducted or withheld
may, depending on individual circumstances, be available to a holder of Junior
Subordinated Debentures 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
Junior Subordinated Debentures are attributable.
 
  Holders of Trust Securities should be aware that under current UK tax law
upon the issuance of Definitive Registered Debentures, the Interest Payments
on such Definitive Registered Debentures will (subject to any entitlement to
make a claim under the provisions of an applicable double tax treaty as
described above) become subject to UK withholding tax, currently at the rate
of 20%. Holders of Definitive Registered Debentures (including the Trust) will
be entitled to the payment of Additional Amounts in respect of the tax
withheld, except as set forth under "Description of the Junior Subordinated
Debentures--Additional Amounts" and under "Description of the Junior
Subordinated Debentures--Form, Book-Entry Procedures and Transfer--Definitive
Registered Debentures", and then subject to the right of Yorkshire Finance in
certain circumstances to redeem the Junior Subordinated Debentures. See
"Description of the Junior Subordinated Debentures--Optional Tax Redemption".
 
  Interest Payments on the Junior Subordinated Debentures constitute UK-source
income 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
such income from a UK source beneficially owned 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 income. This limitation on the UK
tax charge will not apply if such income is beneficially owned by a person who
is not resident for tax purposes in the UK if that person carries on a trade,
profession or vocation in the UK through a UK branch or agency in connection
with which the income is received or to which the Junior Subordinated
Debentures are attributable. There are in any case exemptions for certain
types of income received by certain categories of UK agent (such as some
brokers and investment managers) on behalf of non-UK resident persons.
 
  Where the Junior Subordinated Debentures are held by the Trust and any
holder of Trust Securities is a UK resident, special considerations apply.
Section 128(5) Finance Act 1995 provides "This section [i.e. the section
providing the limitation on the UK tax charge referred to in the second
sentence of the previous paragraph above] shall NOT apply to the income tax
chargeable for any year of assessment on the income of trustees NOT resident
in the United Kingdom if there is a relevant beneficiary of the trust who is
either: (a) an individual ordinarily resident in the United Kingdom; or (b) a
company resident in the United Kingdom". It is not entirely clear, as a
 
                                      108
<PAGE>
 
matter of law, whether Section 128(5) applies where the trust in question is
one under the terms of which the beneficiaries are entitled to the underlying
income of the trust as and when it arises. However, as a matter of practice,
it is understood that the UK Inland Revenue does not currently seek to apply
Section 128(5) to such trusts. Consequently, if the holders of Trust
Securities are entitled to the underlying income of the Trust as and when it
arises, it is not anticipated that the UK Inland Revenue will seek to assess
the Trust directly even if any holder of Trust Securities is UK-resident.
 
  No stamp duty or stamp duty reserve tax ("SDRT") will be payable on the
issue or transfer by delivery of the Junior Subordinated Debentures.
 
US FEDERAL INCOME TAX CONSIDERATIONS
   
  The following opinion of Dewey Ballantine LLP, counsel to Yorkshire Group,
Yorkshire Finance and the Trust ("Tax Counsel"), describes the material US
Federal income tax consequences of the acquisition, ownership and disposition
of the Trust Securities by purchasers upon original issuance that are US
citizens or residents, corporations, partnerships or other entities created or
organized in or under the laws of the US or any state thereof, an estate, the
income of which is subject to US Federal income taxation regardless of its
source or a trust, the administration of which is subject to the primary
supervision of a US court and for which one or more US persons have the
authority to control all substantial decisions, in each case that are resident
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 that hold
their beneficial interest in the Trust Securities as capital assets. This
opinion so far as it relates to matters of law or legal conclusions is based
upon the provisions of the US Internal Revenue Code of 1986, as amended (the
"Code"), the Treasury regulations promulgated thereunder and administrative
and judicial interpretations thereof now in effect, all of which are subject
to change, possibly with retroactive effect. This opinion does not discuss all
aspects of US Federal income taxation (for example, alternative minimum tax
consequences) 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. This
opinion does not deal with certain classes of US persons subject to special
treatment under the US Federal income tax laws (for example, dealers in
securities, banks, regulated investment companies, life insurance companies,
tax exempt organizations or persons whose functional currency is not the US
dollar).     
 
  The Trust Securities are not being marketed to persons that would not
constitute US Holders ("non-United States Persons") and, consequently, the
following discussion does not discuss the tax consequences that might be
relevant to non-United States Persons. NON-UNITED STATES PERSONS SHOULD
CONSULT THEIR OWN TAX ADVISORS AS TO THE SPECIFIC US FEDERAL INCOME TAX
CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF TRUST SECURITIES.
 
  Tax Counsel has advised that there is no authority directly on point dealing
with securities such as the Trust Securities or transactions of the type
described herein and that the opinions expressed herein are not binding on the
Internal Revenue Service ("IRS") or the courts, either of which could take a
contrary position. No rulings have been or will be sought from the IRS.
Accordingly, there can be no assurance that the IRS will not challenge the
opinions expressed herein or that a court would not sustain such a challenge.
 
  PROSPECTIVE PURCHASERS OF TRUST SECURITIES SHOULD CONSULT, AND SHOULD RELY
UPON, THEIR TAX ADVISORS WITH RESPECT TO THE TAX CONSEQUENCES TO THEM OF THE
PURCHASE, OWNERSHIP AND DISPOSITION OF THE TRUST SECURITIES, INCLUDING THE TAX
CONSEQUENCES UNDER STATE, LOCAL, FOREIGN, AND OTHER TAX LAWS AND THE POSSIBLE
EFFECTS OF CHANGES IN US FEDERAL OR OTHER TAX LAWS. FOR A DISCUSSION OF THE
POSSIBLE REDEMPTION OF THE TRUST SECURITIES OR REDEMPTION OF THE JUNIOR
SUBORDINATED DEBENTURES UPON THE OCCURRENCE OF CERTAIN TAX EVENTS, SEE
"DESCRIPTION OF THE TRUST SECURITIES--REDEMPTIONS" AND "DESCRIPTION OF THE
JUNIOR SUBORDINATED DEBENTURES--OPTIONAL TAX REDEMPTION", RESPECTIVELY.

 Classification of the Trust
 
  Tax Counsel is of the opinion that, under current law, and assuming full
compliance with the terms of the Indenture and the Trust Agreement, the Trust
will be classified as a grantor trust for US Federal income tax purposes and
not as an association or a publicly traded partnership taxable as a
corporation. Accordingly, for US Federal income tax purposes, each US Holder
will be considered the beneficial owner of a pro rata undivided interest in
the Junior Subordinated Debentures held by the Trust, and each US Holder will
be required to include in its gross income its allocable share of the entire
income attributable to the Junior Subordinated Debentures. Each US Holder
generally will determine its net income or loss with respect to the Trust in
accordance with its own method of accounting, although income arising from
OID, if any, must be taken into account under the accrual method of accounting
even if the US Holder otherwise would use the cash receipts and disbursements
method.
 
 Classification of the Junior Subordinated Debentures
 
  Yorkshire Group, Yorkshire Finance, the Trust and the holders of Trust
Securities (by acceptance of a beneficial interest in a Trust Security) will
agree to treat the Junior Subordinated Debentures as indebtedness of Yorkshire
Finance for all US Federal income tax purposes. Tax Counsel is of the opinion
that, under current law, and assuming full compliance with the terms of the
Indenture, the Junior Subordinated Debentures will be classified as
indebtedness of Yorkshire Finance for US Federal income tax purposes.
 
 Original Issue Discount
   
  Under Treasury regulations applicable to debt instruments issued on or after
August 13, 1996 (the "Regulations"), it is the opinion of Tax Counsel that,
for the reasons described in the immediately following paragraph, the Junior
Subordinated Debentures will not be treated as issued with OID.     
   
  The terms of the Junior Subordinated Debentures permit Yorkshire Finance to
defer the payment of interest on the Junior Subordinated Debentures at any
time and from time to time for up to 20 consecutive quarters with respect to
each Extension Period; provided, however, that no Extension Period may extend
beyond the Stated Maturity of the Junior Subordinated Debentures. Under the
Regulations, a "remote" contingency that stated interest will not be timely
paid will be ignored in determining whether a debt instrument is issued with
OID. Yorkshire Finance believes that the likelihood of its exercising its
option to defer Interest Payments is "remote" since exercising that option
would prevent Yorkshire Finance and Yorkshire Group from declaring dividends
on any class of its equity securities. Accordingly, it is the opinion of Tax
Counsel, and Yorkshire Finance intends to take the position, that interest on
the Junior Subordinated Debentures generally will be taxable to a US Holder as
ordinary income at the time it is paid or accrued in accordance with such
holder's method of accounting. It should be noted that the Regulations have
not yet been addressed in any rulings or other interpretations by the IRS.
Accordingly, it is possible that the IRS could take a position contrary to the
interpretations described herein.     
 
  Under the Regulations, if Yorkshire Finance were to exercise its option to
defer Interest Payments, the Junior Subordinated Debentures would at that time
be treated as reissued with OID, and all stated interest on the Junior
Subordinated Debentures would thereafter be treated as OID as long as the
Junior Subordinated Debentures remain outstanding. In such event, all of a US
Holder's taxable interest income with respect to the Junior Subordinated
Debentures would thereafter be accounted for on an economic accrual basis
regardless of such holder's method of tax accounting, and actual distributions
of stated interest would not be reported as taxable income. Consequently, a US
Holder would be required to include in gross income OID even though Yorkshire
Finance would not make actual cash payments during an Extension Period.
Moreover, under the Regulations, if the option to defer Interest Payments was
determined not to be "remote," the Junior Subordinated Debentures would be
treated as having been originally issued with OID. In such event, all of a US
Holder's taxable interest income with respect to the Junior Subordinated
Debentures would be accounted for on
 
                                      110
<PAGE>
 
an economic accrual basis regardless of such holder's method of tax
accounting, and actual distributions of stated interest would not be reported
as taxable income.
 
  The Regulations have not yet been addressed in any rulings or other
interpretations by the IRS, and it is possible that the IRS could take a
position contrary to Tax Counsel's interpretation herein.
 
  Because income on the Trust Securities will constitute interest or OID,
corporate holders of the Trust Securities will not be entitled to a dividends-
received deduction with respect to any income recognized with respect to the
Trust Securities. In the case of a US Holder other than a corporation, such
income in general will also constitute "investment income" for purposes of
determining the deduction allowable for investment interest expense.
 
  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
Additional Amounts will generally be treated as foreign source passive income
or, if income were subject to a foreign withholding tax of five percent or
more, high withholding tax interest (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 rules to their particular situation.
 
 Market Discount
 
  A US Holder of a Trust Security at a discount from face (or the adjusted
issue price if the Trust Security bears OID) of such purchaser's pro rata
share of the Junior Subordinated Debentures acquires such Trust Security with
"market discount." However, market discount with respect to a Trust Security
will be considered to be zero if it is de minimis. Market discount will be de
minimis with respect to a Trust Security if it is less than the product of (i)
0.25% of the adjusted issue price of the purchaser's pro rata share of the
Junior Subordinated Debentures multiplied by (ii) the number of complete years
to maturity of such Junior Subordinated Debentures after the date of purchase.
The purchaser of a Trust Security with more than a de minimis amount of market
discount generally will be required to treat any gain on the sale, exchange,
redemption or other disposition of all or part of the Trust Securities (or
related Junior Subordinated Debentures) as ordinary income to the extent of
accrued (but not previously taxed) market discount. Market discount generally
will accrue ratably during the period from the date of purchase of such Trust
Security to the maturity date of the Junior Subordinated Debentures, unless
the US Holder irrevocably elects to accrue such market discount on the basis
of a constant interest rate.
 
  A US Holder who has acquired a Trust Security at a market discount generally
will be required to defer any deductions of interest expense attributable to
any indebtedness incurred or continued to purchase or carry the Trust
Security, to the extent such interest expense exceeds the related interest
income. Any such deferred interest expense generally will be allowable as a
deduction not later than the year in which the related market discount income
is recognized. As an alternative to the inclusion of market discount in income
upon disposition of all or a portion of a Trust Security or the related Junior
Subordinated Debentures (including redemptions thereof), a US Holder may make
an election (which may not be revoked without the IRS's consent) to include
market discount income as it accrues on all market discount instruments
acquired by the US Holder during or after the taxable year for which the
election is made. In that case, the preceding deferral rule for interest
expense will not apply.
 
 Disposition of Trust Securities
 
  A US Holder will recognize capital gain or loss on a sale, exchange or other
disposition of Trust Securities, including a redemption for cash, equal to the
difference between the amount realized and the US Holder's adjusted tax basis
in the Trust Securities. Gain or loss recognized by a US Holder on the sale,
exchange or other disposition of Trust Securities held for more than one year
will generally be taxable as long-term capital gain or loss, except to the
extent of any accrued market discount. See "--Market Discount". The maximum
effective
 
                                      111
<PAGE>
 
US Federal income tax rate applicable to gains resulting from the sale of
capital assets held by individuals for more than one year but not more than 18
months is 28%. The maximum effective tax rate on long-term capital gain will
decrease to 20% if the Trust Securities are held for more than 18 months.
 
  A US Holder that sells, exchanges or otherwise disposes of Trust Securities
during a period of deferral of Interest Payments on the Junior Subordinated
Debentures, and prior to the record date for the date on which Distributions
of such amounts are made, will increase its adjusted tax basis in its Trust
Securities by the amount of OID included in income in respect of such deferral
and, to the extent that the adjusted tax basis exceeds the amount realized on
the sale or other disposition of such holder's Trust Securities, recognize a
capital loss. If the US Holder disposes of a Trust Security prior to the
occurrence of an Extension Period, any portion of the amount received from the
purchaser that is attributable to accrued interest will be treated as interest
income to the US Holder (that will only be includible as income to the extent
it previously has not been included in the US Holder's taxable income) and
will not be treated as part of the amount realized for purposes of determining
gain or loss on the disposition of the Trust Security. Subject to certain
limited exceptions, capital losses cannot be applied to offset ordinary income
for US Federal income tax purposes.
 
  For foreign tax credit limitation purposes, gain realized on the sale,
exchange or other disposition of a Trust Security generally will be US source
income. At this time, the source of loss is uncertain because the US Treasury
Department has not yet issued final regulations with respect to the allocation
between foreign and US source income of losses from the sale, exchange or
other disposition of securities such as the Trust Securities.
 
  A US Holder's tax basis in its Trust Securities generally will be equal to
(i) the amount paid by such holder for its Trust Securities, increased by (ii)
the amount includible in income by such holder with respect to its Trust
Securities, including any related accrued OID and market discount included in
taxable income by the US Holder, and reduced by (iii) the amount of cash or
other property distributed to such holder with respect to amounts included in
the holder's tax basis pursuant to clause (ii) hereof. A US Holder that
acquires Trust Securities at different prices may be required to maintain a
single aggregate adjusted tax basis in all of its Trust Securities and, upon
sale or other disposition of some of such Trust Securities, to allocate a pro
rata portion of such aggregate tax basis to the Trust Securities sold or
disposed of (rather than maintaining a separate tax basis in each Trust
Security for purposes of computing gain or loss upon a sale or other
disposition of that Trust Security).
 
 Receipt of Junior Subordinated Debentures or Cash In Certain Circumstances
 
  Yorkshire Finance has the right, at any time, to dissolve the Trust and to
cause Junior Subordinated Debentures to be distributed to the US Holders in
liquidation of the Trust. Such liquidating distribution will generally be tax-
free to each US Holder and will result in each US Holder receiving an
aggregate tax basis in its Junior Subordinated Debentures equal to such
holder's aggregate tax basis in its Trust Securities. A US Holder's holding
period in the Junior Subordinated Debentures will include the holding period
for which the US Holder held the related Trust Securities. If a liquidation of
the Trust occurs following a determination that the Trust is subject to US
Federal income tax with respect to the amounts received on the Junior
Subordinated Debentures, then such liquidation will be taxable to the US
Holders. In that event, gain or loss would be recognized in the amount
measured by the difference between the fair market value of the Junior
Subordinated Debentures received in the liquidation and the US Holder's
aggregate tax basis in its Trust Securities. In such a case, the holding
period for the Junior Subordinated Debentures received in the liquidation
would not include the period during which the Trust Securities were held.
 
  The Junior Subordinated Debentures may be redeemed for cash and the proceeds
of such redemption distributed to US Holders in redemption of their Trust
Securities. Such redemption of the Trust Securities would, for US Federal
income tax purposes, constitute a taxable disposition of the redeemed Trust
Securities, and a US Holder would recognize gain or loss as if it had sold
such redeemed Trust Securities for an amount of cash equal to the proceeds
received upon the redemption. See "--Disposition of Trust Securities".
 
                                      112
<PAGE>
 
  The redemption of only part of a Trust Security will require an allocation
of the US Holder's tax basis in the related Junior Subordinated Debentures
between the portion of the Junior Subordinated Debentures redeemed and the
portion retained by the US Holder in order to determine gain or loss.
 
 Information Reporting and Backup Withholding
 
  Income on the Trust Securities will be reported to US Holders on IRS Form
1099, which should be mailed to US Holders by January 31 following each
calendar year. Payments made on and proceeds from the sale of Trust Securities
may be subject to a "backup withholding" tax of 31% unless the US Holder
complies with certain identification requirements. Any withheld amount
generally will be allowed as a credit against the US Holder's US Federal
income tax, provided the required information is timely filed with the IRS. In
addition, recently adopted US Treasury regulations, which generally are
effective for payments made after December 31, 1998, subject to certain
transition rules, modify in certain respects the backup withholding and
information reporting rules. In general, the new regulations do not
significantly alter the substantive requirements of these rules, but unify
current procedures and forms and clarify reliance standards. Prospective
purchasers are urged to consult their own tax advisors regarding the new
regulations.
 
CAYMAN ISLANDS TAXATION
 
  It is the opinion of Maples and Calder, Cayman Islands counsel for Yorkshire
Finance, that, under existing Cayman Islands laws:
 
    (i) payments in respect of the Junior Subordinated Debentures will not be
  subject to taxation in the Cayman Islands and no withholding will be
  required on such payments to any holder of the Junior Subordinated
  Debentures and gains derived from the sale of the Junior Subordinated
  Debentures, if distributed, will not be subject to Cayman Islands income or
  corporation tax. The Cayman Islands currently has no income tax or taxation
  in the nature of a withholding tax, corporate or capital tax and no estate
  duty, inheritance tax or gift tax; and
 
    (ii) the holder of a Junior Subordinated Debenture in bearer form (or the
  legal personal representative of such holder) whose Junior Subordinated
  Debenture in bearer form is brought into the Cayman Islands in original
  form may be liable to pay stamp duty imposed under the laws of the Cayman
  Islands in respect of such Junior Subordinated Debenture in bearer form
  (currently up to CI $250 (U.S. $305) per Junior Subordinated Debenture in
  bearer form (unless duty of CI$500 is paid in respect of the series of such
  Junior Subordinated Debentures)). Definitive Registered Debentures and any
  Global Debentures which are evidence of entitlement only and title to which
  passes by entry in the relevant register, will not be subject to Cayman
  Islands stamp duty. Any instrument transferring title to any Junior
  Subordinated Debenture in registered form may be subject to Cayman Islands
  stamp duty of CI$100 if brought to or executed in the Cayman Islands.
 
  Yorkshire Finance has been incorporated under the laws of the Cayman Islands
as an exempted company and, as such, has obtained an undertaking dated
September 9, 1997 from the Governor-in-Council of the Cayman Islands that, for
a period of twenty years from the date of the undertaking, no law enacted in
the Cayman Island imposing any tax to be levied on profits, income, gains or
appreciations shall apply to Yorkshire Finance or its operations and, in
addition, that no tax to be levied on profits, income, gains, or appreciations
or which is in the nature of estate duty or inheritance tax shall be payable
by Yorkshire Finance on or in respect of the shares, debentures or other
obligations of Yorkshire Finance or by way of the withholding in whole or in
part of any relevant payments (as defined in Section 6(3) of the Tax
Concessions Law (1995 Revisions)).

                             ERISA CONSIDERATIONS
 
  A fiduciary of a pension, profit-sharing or other employee benefit plan
subject to ERISA (an "ERISA Plan") should consider the fiduciary standards of
ERISA in the context of the ERISA Plan's particular circumstances before
authorizing an investment in the Trust Securities. Among other factors, the
fiduciary should consider whether such an investment is in accordance with the
documents governing the ERISA Plan and whether the investment is appropriate
for the ERISA Plan in view of its overall investment policy and
diversification of its portfolio.
 
  Certain provisions of ERISA and the Code prohibit ERISA Plans, as well as
individual retirement accounts and Keogh plans subject to section 4975 of the
Code (collectively, "Plans"), from engaging in certain transactions involving
"plan assets" with parties that are "parties in interest" under ERISA or
"disqualified persons" under the Code with respect to the Plan. The U.S.
Department of Labor has issued a final regulation (the "Regulation") with
regard to whether the underlying assets of an entity in which employee benefit
plans acquire equity interests are deemed to be plan assets.
 
  Under such Regulation, for purposes of ERISA and section 4975 of the Code,
the assets of the Trust would be deemed to be "plan assets" of a Plan whose
assets were used to purchase Trust Securities if the Trust Securities were
considered to be equity interests in the Trust and no exception to plan asset
status were applicable under the Regulation.
 
  If the assets of the Trust were deemed to be plan assets of Plans that are
holders of the Trust Securities, a Plan's investment in the Trust Securities
might be deemed to constitute a delegation under ERISA of the duty to manage
plan assets by a fiduciary investing in Trust Securities. In addition,
Yorkshire Group might be considered a "party in interest" or "disqualified
person" with respect to Plans whose assets were used to purchase Trust
Securities. If this were the case, an investment in Trust Securities by a Plan
might constitute or, in the course of the operation of the Trust, give rise to
a prohibited transaction under ERISA or the Code. In particular, it is likely
that, under such circumstances, a prohibited "extension of credit" to
Yorkshire Group would be considered to occur under ERISA and the Code.
 
  Because of the possibility that the assets of the Trust would be considered
plan assets of Plans whose assets were invested in the Trust Securities, and
the likelihood that under such circumstances a prohibited extension of credit
would occur, the Trust Securities may be not purchased or held by any Plan or
any person investing "plan assets" of any Plan, unless such purchaser or
holder is eligible for the exemptive relief available under PTCE 96-23 (for
certain transactions determined by in-house asset managers), PTCE 95-60 (for
certain transactions involving insurance company general accounts), PTCE 91-38
(for certain transactions involving bank collective investment funds), PTCE
90-1 (for certain transactions involving insurance company separate accounts),
or PTCE 84-14 (for certain transactions determined by independent qualified
asset managers). Any purchaser or holder of the Trust Securities or any
interest therein will be deemed to have represented by its purchase and
holding thereof that it either (a) is not a Plan and is not purchasing such
securities on behalf of or with "plan assets" of any Plan or (b) is eligible
for the exemptive relief available under PTCE 96-23, 95-60, 91-38, 90-1 or 84-
14.
 
  Due to the complexity of these rules and the penalties imposed upon persons
involved in prohibited transactions, it is important that any person
considering the purchase of Trust Securities with Plan assets consult with its
counsel regarding the consequences under ERISA and the Code of the acquisition
and ownership of Trust Securities and the availability of exemptive relief
under the class exemptions listed above. In John Hancock Mutual Life Insurance
Co. v. Harris Trust and Savings Bank, 114 S. Ct. 517 (1993), the Supreme Court
ruled that assets held in an insurance company's general account may be deemed
to be "plan assets" for ERISA purposes under certain circumstances. Employee
benefit plans which are governmental plans (as defined in Section 3(32) of
ERISA) and certain church plans (as defined in Section 3(33) of ERISA)
generally are not subject to ERISA requirements.

  Subject to the terms and conditions set forth in the Underwriting Agreement,
the Underwriters are committed to take and pay for all such Trust Securities
offered hereby, if any are taken. Default by one Underwriter would not relieve
any non-defaulting Underwriter from its several obligation, and in the event
of such a default, the non-defaulting Underwriters may be required by the
Trust to purchase the Trust Securities that they have severally agreed to
purchase and, in addition, to purchase the Trust Securities that the
defaulting Underwriter or Underwriters shall have failed to purchase up to an
amount equal to one-ninth of the Trust Securities that such non-defaulting
Underwriter or Underwriters have otherwise agreed to purchase.
 
  The Trust has been advised by the Representative that the Underwriters
propose to offer the Trust Securities in part directly to the public at the
initial public offering price set forth on the cover page of this Prospectus,
and in part to certain securities dealers at such price less a concession of
not to exceed $    per Trust Security. The Underwriters may allow, and such
dealers may reallow, a concession of not to exceed $    per Trust Security to
certain brokers and dealers. After the Trust Securities are released for sale
to the public, the offering price and other selling terms may from time to
time be varied by the Underwriters.
 
  In view of the fact that the proceeds from the sale of the Trust Securities
will be used to purchase the Junior Subordinated Debentures, the Underwriting
Agreement provides that Yorkshire Finance will pay as Underwriters'
Compensation for the Underwriters arranging the investment therein of such
proceeds an amount of $    per Trust Security (or $    in the aggregate);
provided that such compensation for sales of 10,000 or more Trust Securities
to a single purchaser will be $     per Trust Security. Therefore, to the
extent of such sales, the actual amount of Underwriters' Compensation will be
less than the aggregate amount specified in the preceding sentence.
 
  Prior to this offering, there has been no public market for the Trust
Securities. Application has been made to list the Trust Securities on the
NYSE. In order to meet one of the requirements for listing the Trust
Securities on the NYSE, the Underwriters will undertake to sell lots to a
minimum of 400 beneficial holders. If accepted, trading of the Trust
Securities on the NYSE would commence within the 30-day period after the
initial delivery of the Trust Securities. The Underwriters have advised
Yorkshire Group that they intend to make a market in the Trust Securities
prior to commencement of trading on the NYSE, but are not obligated to do so
and may discontinue market making at any time without notice. No assurance can
be given as to the liquidity of the trading market for the Trust Securities.
 
  In connection with the sale of the Trust Securities, the Underwriters may
engage in transactions that stabilize, maintain or otherwise affect the price
of the Trust Securities. Specifically, the Underwriters may bid
 
                                      115
<PAGE>
 
for, and purchase, the Trust Securities in the open market to cover syndicate
short positions or to stabilize the price of the Trust Securities, and in
connection therewith impose a penalty bid on certain Underwriters and selling
group members. This means that if the Underwriters purchase Trust Securities in
the open market to reduce any short position or to stabilize the price of the
Trust Securities, they may reclaim the amount of the selling concession from
the Underwriter or Underwriters and selling group members who sold those Trust
Securities as part of this offering. Any of these activities may stabilize or
maintain the market price of the Trust Securities above independent market
levels. The Underwriters will not be required to engage in these activities and
may end any of these activities at any time.
 
  Yorkshire Group, Yorkshire Finance and the Trust have agreed, during the
period of 30 days from the date of the Underwriting Agreement, not to sell,
offer to sell, grant any option for the sale of, or otherwise dispose of any
Trust Securities, any security convertible into or exchangeable into or
exercisable for Trust Securities or the Junior Subordinated Debentures or debt
securities substantially similar to the Junior Subordinated Debentures or
equity securities substantially similar to the Trust Securities (except for the
Junior Subordinated Debentures and the Trust Securities issued pursuant to the
Underwriting Agreement), without the prior written consent of the
Representative.
 
  Each Underwriter has also agreed that (a) it has not offered or sold and,
prior to the date six months after the date of issuance of the Trust
Securities, will not offer or sell any Trust Securities 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 and
will not result in an offer to the public in the UK within the meaning of the
Public Offers of Securities Regulations 1995, (b) it has complied, and will
comply with all applicable provisions of the Financial Services Act 1986 of
Great Britain with respect to anything done by it in relation to the Trust
Securities in, from or otherwise involving the UK, and (c) 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 issuance of the Trust Securities to a person who
is of a kind described in Article 11(3) of the Financial Services Act 1986
(Investment Advertisements) (Exemptions) Order 1996 (as amended) or is a person
to whom such document may otherwise lawfully be issued or passed on.
 
  Each of the Underwriters has severally represented and agreed that it has not
and will not make any invitation to the public in the Cayman Islands to
purchase any Junior Subordinated Debentures or any Trust Securities, whether
directly or indirectly.
 
  Yorkshire Group and Yorkshire Finance have agreed to indemnify the several
Underwriters against certain liabilities, including liabilities under the
Securities Act, or to contribute to payments that the Underwriters may be
required to make in respect thereof.
 
  Certain of the Underwriters or their affiliates have provided from time to
time, and expect to provide in the future, investment or commercial banking
services to Yorkshire Group and its affiliates, for which such Underwriters or
their affiliates have received or will receive customary fees and commissions.

                         INDEPENDENT AUDITORS' REPORT
 
To the Shareholder and Board of Directors
of Yorkshire Electricity Group plc
 
  We have audited the accompanying consolidated balance sheets of Yorkshire
Electricity Group plc and its subsidiaries (the "Company") as of March 31,
1997 and 1996, and the related consolidated statements of income, changes in
shareholders' equity and cash flows for each of the three years in the period
ended March 31, 1997 (all expressed in pounds sterling). These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards in the United States of America. Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.
 
  In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Yorkshire Electricity Group
plc and its subsidiaries as of March 31, 1997 and 1996, and the results of
their operations and their cash flows for each of the three years in the
period ended March 31, 1997 in conformity with generally accepted accounting
principles in the United States of America.

                NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
GENERAL
 
  Yorkshire Electricity Group plc ("YEG" or the "Company") 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. The Company's main business, the
distribution and supply of electricity to customers in its franchise area (the
"Franchise Area") in the North of England, is regulated under the terms of a
Public Electricity Supply License ("PES License") by the Office of Electricity
Regulation ("OFFER").
 
  The Company operates primarily in its Franchise Area in Northern England.
The Franchise Area covers approximately 10,000 square kilometers, encompassing
parts of the counties of West Yorkshire, Humberside, South Yorkshire,
Derbyshire, Nottinghamshire, Lincolnshire and Lancashire. The Franchise Area
has a resident population of approximately 4.4 million.
 
  The Company purchases power primarily from the wholesale trading market for
electricity in England and Wales (the "Pool"). The Pool monitors supply and
demand between generators and suppliers, sets prices for generation and
provides for centralized settlement of accounts due between generators and
suppliers.
 
BASIS OF PRESENTATION
 
  The consolidated financial statements of the Company are presented in pounds
sterling ((Pounds)) and in conformity with accounting principles generally
accepted in the United States of America. The Company is not subject to rate
regulation but rather, is subject to price cap regulation and, therefore, the
provisions of Statement of Financial Accounting Standards No. 71, "Accounting
for the Effects of Certain Types of Regulation" do not apply.
 
PRINCIPLES OF CONSOLIDATION
 
  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 the Company in the UK. Significant intercompany
items are eliminated in consolidation.
 
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.
 
UNBILLED REVENUE
 
  The Company records revenue net of value added tax ("VAT") and accrues
revenues for service provided but unbilled at the end of each reporting
period.
 
RECOVERY OF REGULATED INCOME
 
  Charges for distribution of electricity and for supply to customers with a
maximum demand under 100 kW are subject to a price control formula set out in
the Company's PES License which allows a maximum charge per unit of
electricity. Differences in the charges, or in the purchase cost of
electricity, can result in the under or overrecovery of revenues in a
particular period.

               YORKSHIRE ELECTRICITY GROUP PLC AND SUBSIDIARIES
                             (PREDECESSOR COMPANY)
 
          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  Where there is an overrecovery of supply or distribution business revenues
against the regulated maximum allowable amount, revenues are deferred in an
amount equivalent to the overrecorded amount. The deferred amount is deducted
from operating revenues and included in other current liabilities.
 
FINANCIAL INSTRUMENTS
 
  The Company enters into contracts for differences ("CFDs") primarily to
hedge its supply business against the price risk of electricity purchases from
the Pool. Use of these CFDs is carried out within the framework of the
Company's purchasing strategy and hedging guidelines. CFDs are accounted for
as hedges and, consequently, gains and losses are deferred and recognized over
the same period as the item hedged. The Company recognizes gains (losses) on
CFDs when settlement is made, which is generally monthly. Gains (losses) on
CFDs are recognized as a decrease (increase) to cost of sales based upon the
difference between fixed prices in the CFD compared to variable prices paid to
the Pool for the period. Gains (losses) based upon the difference between
fixed prices in the CFD compared to variable prices paid to the Pool for
future electricity purchases are not recognized until the period of such
settlements.
 
  The Company enters into interest rate swaps as a part of its overall risk
management strategy and does not hold or issue material amounts of derivative
financial instruments for trading purposes. The Company accounts for its
interest rate swaps in accordance with Statement of Financial Accounting
Standards No. 80, "Accounting for Futures Contracts" and various Emerging
Issues Task Force pronouncements. If the interest rate swaps were to be sold
or terminated, any gain or loss would be deferred and amortized over the
remaining life of the debt instrument being hedged by the interest rate swap.
If the debt instrument being hedged by the interest rate swap were to be
extinguished, any gain or loss attributable to the swap would be recognized in
the period of the transaction.
 
  The Company considers the carrying amounts of financial instruments
classified as current assets and current liabilities to be a reasonable
estimate of their fair value because of the short maturity of these
instruments.
 
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 is stated at original cost, which includes
materials, labor and appropriate overhead costs, and the estimated cost of
borrowed funds used during construction. The cost of maintenance, repairs and
replacement of minor items of property is charged to maintenance expense.
 
  The Company records book depreciation expense on a straight-line basis,
except for distribution network assets which are charged at 3% for 20 years
and 2% for the remaining 20 years. Assets are depreciated using the following
estimated useful lives:

temporary differences reverse.
 
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 on December 1, 1991. From
April 1, 1995 new employees are only eligible to join this plan. The assets of
the defined contribution plan are held and administered by an independent
trustee. The cost recognized for this plan was less than (Pounds)1 million for
each of the three fiscal years ended March 31, 1997.
 
DEFINED BENEFITS
 
  The Company 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 UK.
 
  The Company uses the projected unit credit actuarial method for accounting
purposes. Amounts funded to the pension are primarily invested in equity and
fixed income securities.
 
  Statement of Financial Accounting Standards No. 87 "Employers' Accounting
For Pensions" ("SFAS 87") was effective for fiscal years beginning after
December 15, 1988. The provisions of SFAS No. 87 were initially adopted by the
Company on April 1, 1992. The amount of the unrecognized net transition
obligation on April 1, 1992 was (Pounds)51 million.

3. REGULATORY MATTERS
 
  The distribution business of the Company is regulated under its PES License,
pursuant to which revenue of the distribution business is controlled by the
Distribution Price Control Formula (the "DPCF"). The DPCF determines the
maximum average price per unit of electricity (expressed in kilowatt hours)
that the Company can charge. The DPCF 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 adjust the value of certain elements in the DPCF. The Company's allowed
distribution revenues were reduced by a 14% below inflation reduction and a
13% below inflation reduction on April 1, 1995 and 1996, respectively,
following a review by the Regulator. On April 1, 1997 and April 1, 1998, the
Company's allowed distribution revenues were decreased by an additional 3%
below inflation reduction and there will be a further annual 3% below
inflation reduction on April 1, 1999.

                             (PREDECESSOR COMPANY)
 
          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  The Company's supply business is also regulated by the Regulator, and prices
are established based upon the Supply Price Control Formula which is similar
to the DPCF; however, it currently allows full pass through for all properly
incurred costs.
 
  The non-franchise supply market, which typically includes larger commercial
and industrial customers was opened to competition for all customers with
usage above 1MW upon privatization of the industry in 1990. The non-franchise
supply markets of 100 kW or more were opened to full competition in April
1994.
 
  Currently, the Company, under its PES License, has the exclusive right to
supply residential and small commercial and industrial customers within its
Franchise Area. However, it is anticipated that the supply market will become
fully competitive over a several month period beginning September 1998.
 
4. COMMITMENTS AND CONTINGENCIES
 
ELECTRICITY AND GAS PURCHASE AGREEMENTS
 
  The Company and its subsidiaries have entered into contracts for purchases
of electricity and gas for a period of up to 2009. A provision of (Pounds)78
million has been made for the net present value of expected future payments in
excess of anticipated recoverable amounts, reflecting management's current
expectations of market prices for electricity following the opening of the
competitive market for franchise supply customers and future gas prices. The
actual net costs are highly sensitive to movements in future prices. The
Company's provision includes amounts in respect of contracts with a non
wholly-owned subsidiary.
 
  The Company has additional contracts with unaffiliated parties relating to
the purchase of gas which expire by October 2005, the terms of which are
immaterial with respect to quantity and price, both annually and in the
aggregate.
 
LEGAL PROCEEDINGS
 
  The Company is a party to legal proceedings arising in the ordinary course
of business which are not material, either individually or in the aggregate,
nor is it currently aware of any threatened material legal proceedings.
 
OPERATING LEASES
 
  The Company has commitments under operating leases with various terms and
expiration dates. At March 31, 1997 estimated minimum rental commitments for
noncancelable operating leases were (Pounds)2 million and (Pounds)1 million
for the fiscal years ending March 31, 1998 and 1999, respectively. Rental
expenses incurred for operating leases were (Pounds)4 million, (Pounds)5
million, and (Pounds)8 million during fiscal years 1997, 1996 and 1995,
respectively.
 
LABOR SUBJECT TO COLLECTIVE BARGAINING AGREEMENTS
 
  The majority of the Company's employees are subject to one of three
collective bargaining agreements. Such agreements are ongoing in nature, and
the Company's employees' participation level is consistent with that of the
electric utility industry in the UK.
 
5. SEGMENT REPORTING
 
  The Company is primarily engaged in two electric industry segments;
distribution, which involves the transmission of electricity across its
network to its customers, and supply, which involves bulk purchase of
electricity from the Pool for delivery to the distribution networks. Included
in "Other" are insignificant operating

Inland Revenue in the UK. In the opinion of management, the final settlement

7. FINANCIAL INSTRUMENTS
 
  The Company 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 30,662 GWh
through the year 2009. Accordingly, the gains and losses on such contracts are
deferred and recognized as electricity is purchased. Management's estimate of
the fair value of CFDs outstanding at March 31, 1997 is a net liability of
(Pounds)22 million. This estimate is based on management's projections of
future prices of electricity. The net liability will be recovered through
electricity costs passed through to franchise customers during the fiscal year
ended March 31, 1998.

          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  The Company is exposed to losses in the event of non-performance 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.
 
  As part of its risk management policy, the Company enters into interest rate
swap agreements under which counterparties have agreed to pay amounts to the
Company equal to variable interest obligations in consideration of amounts
payable by the Company equivalent to fixed rates of interest. If the
counterparty to the interest rate swap was to default on contractual payments,
the Company could be exposed to increased costs related to replacing the
original agreement. At March 31, 1996, the Company was party to interest rate
swap agreements with a notional value of (Pounds)89 million which were at
fixed interest rates varying between 6.64% and 10.98%. During the fiscal year
ended March 31, 1997, the Company terminated these agreements at a cost of
(Pounds)7 million.
 
  The estimated fair value of the Company's financial instruments are as
follows (in millions):

  Arrangements have been put in place to entitle the British Government to a
proportion of any property gain (above certain thresholds) accruing as a
result of disposals, or events treated as disposals for these purposes,
occurring after March 31, 1990 in relation to land in which the Company had an
interest at that date (and, in certain circumstances, land in which the
Company acquires an interest thereafter from other members of the electricity
industry) and any buildings on that land. These arrangements will last until
March 31, 2000.

9. SYSTEMS DEVELOPMENT COSTS
 
  During the year ended March 31, 1997, a (Pounds)50 million charge to earnings
was recorded for costs incurred related to information systems development
costs pertaining to the opening up of the competitive electricity market in
1998. It is management's opinion that, at this stage in the development of the
future commercial and regulatory environment, it would not be prudent to
capitalize these costs.

  At March 31, 1997 and 1996 unused committed bank facilities were available
to the Company in the amount of (Pounds)250 million. Commitment fees of
approximately 1/10 of 1% of the unused committed bank facilities are required
to maintain the facilities which have expiration dates between 2000 and 2002.
In addition, the Company has commercial paper programs (denominated in US
dollars) which provide for the issuance of up to $550 million in commercial
paper with short-term maturities (up to 364 days) issued at a discount to face
value.
 
12. DISTRIBUTION OF NATIONAL GRID INVESTMENT
 
  At April 1, 1995, the Company's investment in the issued share capital of
National Grid Group plc ("NGG"), formerly National Grid Holdings plc, was
recorded at (Pounds)72 million, the estimated fair value at privatization.
During December 1995 the following transactions relating to the Company's NGG
investment occurred:
 
    a) Special dividends of (Pounds)118 million (pre-tax) were paid by NGG to
  the Company and recognized in other income. The Company reinvested
  (Pounds)16 million of this dividend in additional NGG shares.
 
    b) NGG became listed on the London Stock Exchange and therefore, the
  Company revalued its investment in NGG to its fair market value of
  (Pounds)321 million.
 
    c) The Company distributed, in kind, approximately 90% of its NGG shares
  to its shareholders and recognized a gain of (Pounds)210 million within
  other income.
 
    d) A (Pounds)50 discount to each of the Company's residential customers
  was provided. The net effect of the customer discount in the amount of
  (Pounds)85 million has been recorded as other expense during the year ended
  March 31, 1996.
 
  In November 1995, NGG also distributed to the RECs its ownership shares in
PSB Holdings Limited ("PSB") based on their respective ownership percentages
of NGG. The PSB shares were revalued at their estimated market value of
(Pounds)56 million. In December 1995 this investment was sold and a gain on
sale of (Pounds)56 million was recognized. In the year to March 31, 1997
further consideration of (Pounds)6 million was received.
 
  In order that holders of options in the Company's shares were not
disadvantaged by the NGG transactions, the Company's Directors established a
new employee share trust. The Company contributed (Pounds)9 million to the
trust which was used to purchase NGG shares from the Company. This
contribution was recorded as a dividend. A corresponding gain of (Pounds)5
million was recognized upon distribution of NGG shares from the trust to
option holders during the year ended March 31, 1996.
 
13. EMPLOYEE OPTION AND SHARE PLANS
 
  The Company operates various employee option and share plans. During the
fiscal year 1995, an Executive Long Term Share Incentive Scheme for certain
eligible Executive Directors was introduced. Under the scheme amounts (as
determined by the earnings per share and market value growth of YEG) were paid
to a trust to be utilized to purchase Company shares. After the final
determination of the amounts in the first cycle of 1998, the shares were to
have been released to participants. Amounts transferred were expensed. 54,025
shares and 23,951 shares were held in trust at March 31, 1997 and 1996,
respectively.
 
  On July 1, 1996 a trust related to the Company's Profit Sharing Scheme
purchased 243,356 ordinary shares of the Company for (Pounds)1,769,198 or
(Pounds)7.27 per share. 64 shares were allocated to each eligible employee.
The net cost of acquiring the shares and maintaining the trust was borne by
the Company.

          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  In connection with the acquisition (note 14), all shares held in the above
trusts were transferred to employees in accordance with the provisions of the
schemes.
 
  The Company had two option plans, the Executive Share Option Scheme and the
Savings-Related Share Option Scheme. The Executive Share Option Scheme
provides for the granting of stock options to purchase ordinary shares to
certain key executives of the Company at the discretion of the Renumeration
Committee of the Company. The options vest three years from the date of grant
and expire ten years after the date of grant. Options to purchase ordinary
shares of the Company have been granted to employees under the Savings-Related
Share Option Schemes adopted in 1996 and 1997. The options vest five years
from date of grant and expire five and a half years after the date of grant.
 
  The following table summarizes the transactions of the share option scheme
for the three year period ended March 31, 1997:

  In connection with the acquisition, holders of any outstanding options were
given the opportunity to exercise their options and sell their shares to
Yorkshire Holdings plc at a price of (Pounds)9.27 per share. If the holders of
the options did not exercise their options, such options were cash cancelled
and the holders were paid (Pounds)9.27 per share less the option's exercise
price.
 
  The Company accounts for its share-based compensation schemes in accordance
with Accounting Principles Board Opinion No. 25, " Accounting for Stock Issued
to Employees". Compensation expense of (Pounds)1 million was recognized in
1997, 1996 and 1995. Because of the change in control of the Company and the
immaterial impact on net income of applying the fair value method, the
disclosures required by Statement of Financial Accounting Standard No. 123,
"Accounting for Stock-Based Compensation", have not been presented.

          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
14. SUBSEQUENT EVENTS
 
  On February 24, 1997 the Boards of American Electric Power Company, Inc.
("AEP") and Public Service Company of Colorado ("PS Colorado") announced the
terms of a cash offer for Yorkshire Electricity Group plc to be made by
Yorkshire Holdings plc, a subsidiary of Yorkshire Power Group Limited. The
offer was declared wholly unconditional on April 1, 1997. On April 16, 1997
notices were issued by Yorkshire Holdings plc in accordance with section 429
of the Companies Act 1985 to acquire all those Yorkshire Electricity Group plc
shares outstanding at the end of the requisite notice period.
 
  Yorkshire Holdings plc completed its purchase of the shares of YEG during
April and May 1997 through payment of cash consideration of (Pounds)1.457
billion and the issuance of loan notes to former YEG shareholders in the
amount of (Pounds)22 million.
 
WINDFALL TAX
 
  On July 2, 1997 the British Government announced a "windfall tax" to be
applied at that date to companies privatized by flotation and regulated by
relevant privatization statutes. A decrease in the UK statutory income tax
rate from 33% to 31% was also included in the legislation. The Company will
record a charge to income of (Pounds)134 million for the windfall tax and an
income tax benefit as a result of the change in the UK statutory income tax
rate of approximately (Pounds)12 million during the quarter ending September
30, 1997. The windfall tax is not deductible for UK income tax purposes and is
payable in two equal installments on or before December 1, 1997 and 1998.
 
BUSINESS RESTRUCTURING
 
  On December 4, 1997 a planned business restructuring was announced. The
restructuring will result in the Company's main divisions (electricity
distribution and energy supply) becoming self sufficient businesses within the
group structure. A separate ownership structure will be pursued for the
generation business. As a result of the restructuring approximately 160
positions will no longer be required. The estimated cost of this restructuring
is (Pounds)10 million.
 
IONICA
 
  Following a profits warning issued by Ionica Group plc ("Ionica") in
November 1997, the fair value of the Company's investment in Ionica decreased
from (Pounds)54 million at April 1, 1997 to (Pounds)30 million at December 31,
1997. The reduction is not regarded by management as a permanent diminution in
value.

(1) To reflect the interest expense recorded in connection with the
    Acquisition financed by (Pounds)22 million loan notes issued by Yorkshire
    Holdings plc ("Yorkshire Holdings") and (Pounds)1,034 million in short-
    term debt incurred by the Successor Company and share capitalization of
    (Pounds)440 million. The loan notes issued by Yorkshire Holdings are
    redeemable at the option of the bond holder until 2000. An interest rate
    of 7% has been assumed for both types of debt. The impact of a 1/8% change
    in the assumed interest rate would affect net income by (Pounds)1 million.
(2) Amortization of goodwill recorded in connection with the Acquisition.
(3) Additional depreciation expense that would have been recorded in
    connection with the Acquisition.
(4) To remove the effect of recording the provision for uneconomic gas and
    electricity contracts ((Pounds)78 million), loss on interest rate swap
    agreements ((Pounds)7 million) and write-down of non-operational
    properties ((Pounds)6 million). If the Acquisition had occurred on April
    1, 1996, these items would have been accounted for as fair value
    adjustments at that date.

    translated into US dollars at the Noon Buying Rate on December 31, 1997 of
    $1.64=(Pounds)1. See "Presentation of Certain Information and Exchange
    Rates" in this Offering Memorandum.
 
  During the pro forma fiscal year ended March 31, 1997, the Predecessor
Company incurred expenses of (Pounds)8.0 million relating to the Acquisition.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
GENERAL
 
  Yorkshire Power Group Limited ("YPG" or the "Company") is a joint venture
formed by subsidiaries of American Electric Power Company, Inc. and Public
Service Company of Colorado for the purpose of acquiring the entire issued
share capital of Yorkshire Electricity Group plc ("YEG"). The acquisition of
YEG was made effective as of April 1, 1997 by Yorkshire Holdings plc, a
wholly-owned subsidiary of YPG.
 
  YEG 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. YEG's
main business, the distribution and supply of electricity to customers in its
franchise area (the "Franchise Area"), is regulated under the terms of YEG's
Public Electricity Supply License ("PES License") by the Office of Electricity
Regulation ("OFFER").
 
  YEG operates primarily in its Franchise Area in Northern England. YEG's
Franchise Area covers approximately 10,000 square kilometers, encompassing
parts of the counties of West Yorkshire, Humberside, South Yorkshire,
Derbyshire, Nottinghamshire, Lincolnshire and Lancashire. The Franchise Area
has a resident population of approximately 4.4 million.
 
  The Company purchases power primarily from the wholesale trading market for
electricity in England and Wales (the "Pool"). The Pool monitors supply and
demand between generators and suppliers, sets prices for generation and
provides for centralized settlement of accounts due between generators and
suppliers.
 
BASIS OF PRESENTATION
 
  On February 24, 1997, the joint venture partners of the Company announced
the terms of a cash tender offer for Yorkshire Electricity Group plc to be
made by Yorkshire Holdings plc, a subsidiary of the Company. The offer was
declared wholly unconditional on April 1, 1997. On April 16, 1997 notices were
issued by Yorkshire Holdings plc in accordance with section 429 of the
Companies Act 1985 to acquire all YEG shares outstanding at the end of the
requisite notice period.
 
  The acquisition was accounted for using the purchase method of accounting in
accordance with Accounting Principles Board Opinion No. 16, "Accounting for
Business Combinations" ("APB 16"). The purchase price of YEG has been
allocated to the underlying assets and liabilities based on preliminary
estimated fair values at the acquisition date (April 1, 1997). The final
purchase price allocation report has not yet been completed; however, the
Company does not anticipate any material changes based on currently available
information.
 
  The consolidated balance sheet of the Company is presented in pounds
sterling ((Pounds)) and in conformity with accounting principles generally
accepted in the United States of America. The Company is not subject to rate
regulation but rather, is subject to price cap regulation and, therefore, the
provisions of Statement of Financial Accounting Standards No. 71, "Accounting
for the Effects of Certain Types of Regulation" ("SFAS 71") do not apply.
 
  The consolidated balance sheet and certain information in the notes to the
consolidated balance sheet are presented in pounds sterling ((Pounds)) and in
US dollars ($) solely for the convenience of the reader, at the exchange rate
of (Pounds)1= $1.6427, 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 December 31, 1997. This presentation has not been
translated in accordance with Statement of Financial Accounting Standards No.
52, "Foreign Currency Translation". No representation is made that the pounds
sterling amounts have been, could have been, or could be converted into US
dollars at that or any other rate of exchange.

                              (SUCCESSOR COMPANY)
                                 APRIL 1, 1997
 
             NOTES TO THE CONSOLIDATED BALANCE SHEET--(CONTINUED)
 
PRINCIPLES OF CONSOLIDATION
 
  The consolidated balance sheet includes the accounts of the Company and its
wholly-owned and majority-owned subsidiaries and has been prepared from
records maintained by the Company in the UK. Significant intercompany items
are eliminated in consolidation.
 
USE OF ESTIMATES
 
  The preparation of the 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. Actual results could differ from those estimates.
 
UNBILLED REVENUE
 
  The Company records revenue net of value added tax ("VAT") and accrues
revenues for service provided but unbilled at the end of each reporting
period.
 
RECOVERY OF REGULATED INCOME
 
  Charges for distribution of electricity and for supply to customers with a
maximum demand under 100kW are subject to a price control formula set out in
YEG's PES license which allows a maximum charge per unit of electricity.
Differences in the charges, or in the purchase cost of electricity, can result
in the under or over recovery of revenues in a particular period.
 
  Where there is an overrecovery of supply or distribution business revenues
against the regulated maximum allowable amount, revenues are deferred in an
amount equivalent to the overrecorded amount and included in other current
liabilities.
 
FINANCIAL INSTRUMENTS
 
  YEG enters into contracts for differences ("CFDs") primarily to hedge its
supply business against the price risk of electricity purchases from the Pool.
Use of these CFDs is carried out within the framework of YEG's purchasing
strategy and hedging guidelines. CFDs are accounted for as hedges and,
consequently, gains and losses are deferred and recognized over the same
period as the item hedged. The Company recognizes gains (losses) on CFDs when
settlement is made, which is generally monthly. Gains (losses) on CFDs are
recognized as a decrease (increase) to cost of sales based upon the difference
between fixed prices in the CFD compared to variable prices paid to the Pool
for the period. Gains (losses) based upon the difference between fixed prices
in the CFD compared to variable prices paid to the Pool for future electricity
purchases are not recognized until the period of such settlements.
 
  The Company enters into interest rate swaps as a part of its overall risk
management strategy and does not hold or issue material amounts of derivative
financial instruments for trading purposes. The Company accounts for its
interest rate swaps in accordance with Statement of Financial Accounting
Standards No. 80, "Accounting for Futures Contracts" and various Emerging
Issues Task Force pronouncements. If the interest rate swaps were to be sold
or terminated, any gain or loss would be deferred and amortized over the
remaining life of the debt instrument being hedged by the interest rate swap.
If the debt instrument being hedged by the interest rate swaps were to be
extinguished, any gain or loss attributable to the swap would be recognized in
the period of the transaction.
 
  The Company considers the carrying amounts of financial instruments
classified as current assets and liabilities to be a reasonable estimate of
their fair value because of the short maturity of these instruments.

             NOTES TO THE CONSOLIDATED BALANCE SHEET--(CONTINUED)
 
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 is recorded at fair market value as adjusted
at the acquisition date in accordance with APB 16. Items capitalized
subsequent to the acquisition will be recorded at original cost, which
includes materials, labor and appropriate overhead costs, and the estimated
cost of borrowed funds used during construction.
 
  The Company's policy is to record depreciation on a straight-line basis,
except for distribution network assets which are charged at 3% for 20 years
and 2% for the remaining 20 years. Assets are depreciated using the following
estimated useful lives:

   Buildings........................................................... Up to 60
   Fixtures and equipment.............................................. Up to 10
   Vehicles and mobile plant........................................... Up to 10
</TABLE>
 
GOODWILL
 
  The Company's policy is to amortize 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 (evaluated 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
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 balance sheet relates to the acquisition of YEG (Note 11).
 
INVESTMENTS
 
  The Company accounts for investments in debt and equity securities in
accordance with Statement of Financial Accounting Standards No. 115,
"Investments in Certain Debt and Equity Securities" ("SFAS 115"). The
Company's investments are classified as available-for-sale under SFAS 115.
Securities whose fair market values are readily determinable are reported at
fair value. Securities whose fair market values are not readily determinable
are recorded at the lower of cost or net realizable value.
 
INCOME TAXES
 
  The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes". This
standard requires that deferred income taxes be recorded for temporary
differences between the financial statement basis and the tax basis of assets
and liabilities and loss carryforwards and that deferred tax balances be based
on enacted tax laws at rates that are expected to be in effect when the
temporary differences reverse.
 
2. RETIREMENT BENEFITS
 
PENSION PLANS
 
  The Company operates two schemes, one based on defined contributions and a
second based on defined benefits.

             NOTES TO THE CONSOLIDATED BALANCE SHEET--(CONTINUED)
 
DEFINED CONTRIBUTION
 
  The defined contribution plan was established on December 1, 1991. From
April 1, 1995 new employees are only eligible to join this plan. The assets of
the defined contribution plan are held and administered by an independent
trustee.
 
DEFINED BENEFITS
 
  The Company 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 UK.
 
  The Company uses the projected unit credit actuarial method for accounting
purposes. Amounts funded to the pension are primarily invested in equity and
fixed income securities.
 
  The following table sets forth the plan's funded status and amounts
recognized in the Company's balance sheet at April 1, 1997 (in millions):

  The weighted average discount rate, expected rate of increase in future
compensation, and the expected long-term rate of return on plan assets used to
determine the plan's funded status were, 8.0%, 6.0% and 9.0%, respectively.
 
3. REGULATORY MATTERS
 
  The distribution business of YEG is regulated under its PES License,
pursuant to which revenue of the distribution business is controlled by the
Distribution Price Control Formula ("DPCF"). The DPCF determines the maximum
average price per unit of electricity (expressed in kilowatt hours) that YEG
can charge. The DPCF 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 adjust
the value of certain elements in the DPCF. YEG's allowed distribution revenues
were reduced by a 14% below inflation reduction and a 13% below inflation
reduction on April 1, 1995 and 1996, respectively, following a review by the
Regulator. On April 1, 1997 and April 1, 1998, YEG's allowed distribution
revenues were decreased by an additional 3% below inflation reduction, and
there will be a further annual 3% below inflation reduction on April 1, 1999.
 
  The supply business of YEG is also regulated by the Regulator, and prices
are established based upon the Supply Price Control Formula which is similar
to the DPCF; however, it currently allows full pass through for all properly
incurred costs.
 
  The non-franchise supply market, which typically includes larger commercial
and industrial customers was opened to competition for all customers with
usage above 1 MW upon privatization of the industry in 1990. The non-franchise
supply markets of 100 kW or more were opened to full competition in April
1994.

                                 APRIL 1, 1997
 
             NOTES TO THE CONSOLIDATED BALANCE SHEET--(CONTINUED)
 
  Currently, YEG, under its PES License has the exclusive right to supply
residential and small commercial and industrial customers within its Franchise
Area. However, it is anticipated that the supply market will become fully
competitive over a several month period beginning September 1998.
 
4. COMMITMENTS AND CONTINGENCIES
 
ELECTRICITY AND GAS PURCHASE AGREEMENTS
 
  The Company and its subsidiaries have entered into contracts for purchases
of electricity and gas for a period of up to 2009. A provision of (Pounds)78
million ($128 million) has been made for the net present value of expected
future payments in excess of anticipated recoverable amounts, reflecting
management's current expectations of market prices for electricity following
the opening of the competitive market to franchise supply customers and future
gas prices. The actual net costs are highly sensitive to movements in future
prices. The Company's provision includes amounts in respect of contracts with
a non wholly-owned subsidiary.
 
  The Company has additional contracts with unaffiliated parties relating to
the purchase of gas which expire by October 2005, the terms of which are
immaterial with respect to quantity and price, both annually and in the
aggregate.
 
LEGAL PROCEEDINGS
 
  The Company is a party to legal proceedings arising in the ordinary course
of business which are not material, either individually or in the aggregate,
nor is it currently aware of any threatened material legal proceedings.
 
OPERATING LEASES
 
  The Company has commitments under operating leases with various terms and
expiration dates. At April 1, 1997 estimated minimum rental commitments for
noncancelable operating leases were (Pounds)2 million ($3 million) and
(Pounds)1 million ($2 million) for the fiscal years ending March 31, 1998 and
1999, respectively.
 
LABOR SUBJECT TO COLLECTIVE BARGAINING AGREEMENTS
 
  A majority of the Company's employees are subject to one of three collective
bargaining agreements. Such agreements are ongoing in nature, and the
Company's employees participation level is consistent with that of the
electric utility industry in the UK.
 
5. SEGMENT REPORTING
 
  The Company is primarily engaged in two electric industry segments;
distribution, which involves the transmission of electricity across its
network to its customers, and supply, which involves bulk purchase of
electricity from the Pool for delivery to the distribution networks. Included
in "Other" are insignificant operating subsidiaries of the Company as well as
various corporate activities, and non-allocated corporate assets. The
Company's assets in these individual segments as of April 1, 1997 are as
follows (in millions):

  The tax years since 1993 are currently under review by the Inland Revenue in
the UK. In the opinion of management, the final settlement of open years will
not have a material effect on financial position.
 
7. FINANCIAL INSTRUMENTS
 
  YEG utilizes contracts for differences ("CFDs") to mitigate its exposure to
volatility in the prices of electricity purchased through the Pool. Such
contracts allow YEG 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 30,662 GWh through the
year 2009. Accordingly, the gains and losses on such contracts are deferred
and recognized as electricity is purchased. Management's estimate of the fair
value of CFDs outstanding at March 31, 1997 is a net liability of (Pounds)22
million. This estimate is based on management's projections of future prices
of electricity. The net liability will be recovered through electricity costs
passed through to franchise customers during the fiscal year ended March 31,
1998.
 
  YEG is exposed to losses in the event of non-performance by counterparties
to its CFDs. To manage this credit risk, YEG 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.

acquires an interest thereafter from other members of the electricity
industry) and any buildings on that land. These arrangements will last until

required to maintain the facilities which have expiration dates between 2000
and 2002. In addition, YEG has commercial paper programs (denominated in US
dollars) which provide for the issuance of up to $550 million in commercial
paper with short-term maturities (up to 364 days) issued at a discount to face
value.
 
11. ACQUISITION
 
  On February 24, 1997 the joint venture partners of the Company announced the
terms of a cash offer for YEG to be made by Yorkshire Holdings plc, a
subsidiary of the Company. The offer was declared wholly unconditional on
April 1, 1997. On April 16, 1997 notices were issued by Yorkshire Holdings plc
in accordance with section 429 of the Companies Act 1985 to acquire all those
YEG shares outstanding at the end of the requisite notice period.
 
  Yorkshire Holdings plc completed its purchase of the shares of YEG during
April and May 1997 through payment of cash consideration of (Pounds)1.457
billion ($2.393 billion) and the issuance of loan notes to former YEG
shareholders in the amount of (Pounds)22 million ($36 million).
 
  The acquisition was financed by cash contributions of (Pounds)220 million
($361 million) from each of the joint venture partners, against which shares
in the Company were subsequently allotted, and borrowings under a
(Pounds)1.140 billion ($1.873 billion) term loan and revolving facility
agreement. The term loan and revolving facility agreement provided for a
revolving credit facility of (Pounds)50 million ($82 million) and a term loan
facility in the aggregate amount of (Pounds)1.090 billion ($1.790 billion).
 
  Effective July 31, 1997 the term loan and revolving credit facility
agreement was replaced with a (Pounds)1.085 billion ($1.782 billion) credit
facility. This credit facility consists of two parts which are Facility A
(term loan facility) for (Pounds)1.034 billion ($1.699 billion) and Facility B
(revolving credit facility) for (Pounds)50 million ($82 million). Facility A
is repayable on July 30, 1998. The interest rates on the facilities are based
on LIBOR plus a margin which ranges from 0.125% to 0.5% dependent on the time
elapsed since the Facility became available, plus a defined margin which is
based on a bank cost of funds. The Facilities contain certain restrictive
covenants which include a maximum consolidated net debt to capitalization
ratio and minimum earnings to interest ratio. The Company intends to partly
repay Facility A, in 1998, through issue, by subsidiaries of the Company, of
bonds and preferred securities, the proceeds of which will be loaned to the
Company.
 
  The acquisition was accounted for using the purchase method of accounting in
accordance with APB 16. The purchase price of YEG has been allocated to the
underlying assets and liabilities based on preliminary estimated fair values
at the acquisition date. The final purchase price allocation report has not
yet been completed; however, the Company does not anticipate any material
changes based on currently available information. The acquisition cost
exceeded the fair market value of net assets acquired, including (Pounds)17
million ($28 million) of acquisition related costs, by (Pounds)994 million
($1.630 billion) and is considered goodwill.
 
  The net purchase price of (Pounds)1.496 billion ($2.453 billion) was
allocated as follows at April 1, 1997 (in millions):

12. EMPLOYEE OPTION AND SHARE PLANS
 
  Prior to the acquisition of YEG by the Company, employees of YEG were
eligible to participate in the 1997 and 1996 Savings-Related Share Option
Schemes, Executive Share Option Scheme, Profit Sharing Scheme, and/or the Long
Term Incentive Scheme. In connection with the acquisition, employees were
given the opportunity to exercise their options granted under the Savings-
Related Share Option Schemes and the Executive Share Option Scheme and sell
their shares to Yorkshire Holdings plc at a price of (Pounds)9.27 ($15.20) per
share. If the holders of the options did not exercise their options, such
options were cash cancelled and the holders were paid (Pounds)9.27 ($15.20)
per share less the option's exercise price. There were 2,815,302 options
outstanding, which were all exercised or cash cancelled subsequent to April 1,
1997.
 
  Prior to April 1, 1997, the following shares of stock were held in trust on
behalf of employees:

  In connection with the acquisition, all shares of YEG issued under the
Profit Sharing Scheme, Long-Term Incentive Scheme, as well as the NGG shares
held in trust for the benefit of certain option holders, were transferred to
employees in accordance with vesting rights as previously established and the
related schemes and trusts were terminated.
 
13. SUBSEQUENT EVENTS
 
  On July 2, 1997 the British Government announced a "windfall tax" to be
applied at that date to companies privatized by flotation and regulated by
relevant privatization statutes. A decrease in the UK statutory income tax
rate, from 33% to 31% was also included in the legislation. The Company will
record a charge to income of (Pounds)134 million ($220 million) for the
windfall tax and an income tax benefit as a result of the change in the UK
statutory income tax rate of approximately (Pounds)12 million ($20 million)
during the quarter ending September 30, 1997. The windfall tax is not
deductible for UK income tax purposes and is payable in two equal installments
on or before December 1, 1997 and 1998.
 
  On December 4, 1997 a planned business restructuring was announced. The
restructuring will result in the Company's main divisions (electricity
distribution and energy supply) becoming self-sufficient businesses within the
group structure. A separate ownership structure will be pursued for the
generation business. As a result of the restructuring approximately 160
positions will no longer be required. The estimated cost of this restructuring
is (Pounds)10 million ($16 million).
 
  Following a profits warning issued by Ionica Group plc ("Ionica") in
November 1997, the fair value of the Company's investment in Ionica decreased
from (Pounds)54 million ($89 million) at April 1, 1997 to (Pounds)30 million
($49 million) at December 31, 1997. The reduction is not regarded by
management as a permanent diminution in value.

                    INDEPENDENT ACCOUNTANTS' REVIEW REPORT
 
To the Shareholders and Board of Directors
of Yorkshire Power Group Limited
 
  We have reviewed the accompanying condensed consolidated balance sheet of
Yorkshire Power Group Limited and subsidiaries (the "Company") as of December
31, 1997 and the related condensed consolidated statements of income, changes
in shareholders' equity and cash flows (all expressed in pounds sterling) for
the nine-month period then ended. These financial statements are the
responsibility of the Company's management.
 
  We conducted our review in accordance with standards established by the
American Institute of Certified Public Accountants. A review of interim
financial information consists principally of applying analytical procedures
to financial data and of making inquiries of persons responsible for financial
and accounting matters. It is substantially less in scope than an audit
conducted in accordance with generally accepted auditing standards, the
objective of which is the expression of an opinion regarding the financial
statements taken as a whole. Accordingly, we do not express such an opinion.
 
  Based on our review, we are not aware of any material modifications that
should be made to such condensed consolidated financial statements for them to
be in conformity with generally accepted accounting principles in the United
States of America.

1. DESCRIPTION OF BUSINESS
 
  Yorkshire Power Group Limited and Subsidiaries ("YPG" or "the Company") is a
joint venture formed by subsidiaries of American Electric Power Company, Inc.
and New Century Energies, Inc. for the purpose of acquiring Yorkshire
Electricity Group plc ("YEG" or the "Predecessor"). The acquisition of YEG was
made effective as of April 1, 1997 by Yorkshire Holdings plc, a wholly-owned
subsidiary of YPG.
 
  YEG 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. YEG's
main business, the distribution and supply of electricity to customers in its
Franchise Area, is regulated under the terms of YEG's Public Electricity
Supply License by the Office of Electricity Regulation ("OFFER").
 
  YEG operates primarily in its Franchise Area in Northern England. YEG's
Franchise Area covers approximately 10,000 square kilometers, encompassing
parts of the counties of West Yorkshire, Humberside, South Yorkshire,
Derbyshire, Nottinghamshire, Lincolnshire and Lancashire. The Franchise Area
has a resident population of approximately 4.4 million.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  The condensed consolidated balance sheet of the Company is presented in
pounds sterling ((Pounds)) and in conformity with accounting principles
generally accepted in the United States of America.
 
  The condensed consolidated financial statements and certain information in
the notes to the condensed consolidated financial statements are presented in
pounds sterling ((Pounds)) and in US dollars ($), solely for the convenience

PRINCIPLES OF CONSOLIDATION
 
  The unaudited condensed consolidated financial statements include the
accounts of the Company and its wholly-owned and majority-owned subsidiaries
and has been prepared from records maintained by the Company in the UK. All
significant intercompany accounts and transactions have been eliminated in

consolidated financial statements reflect all adjustments (consisting of
normal recurring adjustments) considered necessary for the fair presentation
of the financial position and results of operations for the periods presented.
Such unaudited interim financial statements should be read in conjunction with
the audited balance sheet of the Company and financial statements of YEG
contained elsewhere in this Offering Memorandum.
 
PREDECESSOR COMPANY FINANCIAL STATEMENTS

     NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
                                  (UNAUDITED)
consist primarily of the amortization of goodwill, depreciation of fixed
assets valued at a historical cost which is less than the fair value recorded
by the Successor company and interest expense on the borrowings incurred to
finance the acquisition.
 
3. ACQUISITION
 
  On February 24, 1997 the joint venture partners of the Company announced the
terms of a cash offer for YEG to be made by Yorkshire Holdings plc, a
subsidiary of the Company. The offer was declared wholly unconditional on
April 1, 1997. On April 16, 1997 notices were issued by Yorkshire Holdings plc
in accordance with section 429 of the Companies Act 1985 to acquire all YEG
shares outstanding at the end of the requisite notice period.
 
  Yorkshire Holdings plc completed its purchase of the shares of YEG during
April and May 1997 through payment of cash consideration of (Pounds)1.457
billion ($2.393 billion) and the issuance of loan notes to former YEG
shareholders in the amount of (Pounds)22 million ($36 million).
 
  The acquisition was financed by cash contributions of (Pounds)220 million
($361 million) from each of the joint venture partners, against which shares
in the Company were subsequently allotted, and borrowings under a
(Pounds)1.140 billion ($1.873 billion) term loan and revolving facility
agreement. The term loan and revolving facility agreement provided for a
revolving credit facility of (Pounds)50 million ($82 million) and a term loan
facility in the aggregate amount of (Pounds)1.090 billion ($1.790 billion).
 
  Effective July 31, 1997 the term loan and revolving credit facility
agreement was replaced with a (Pounds)1.085 billion ($1.782 billion) credit
facility. This credit facility consists of two parts which are Facility A
(term loan facility) for (Pounds)1.034 billion ($1.699 billion) and Facility B
(revolving credit facility) for (Pounds)50 million ($82 million). Facility A
is repayable on July 30, 1998. The interest rates on the facilities are based
on LIBOR plus a margin which ranges from 0.125% to 0.5% dependent on the time
elapsed since the facility became available, plus a defined margin which is
based on a bank cost of funds. The facilities contain certain restrictive
covenants which include a maximum consolidated net debt to capitalization
ratio and minimum earnings to interest ratio. The Company intends to partly
repay Facility A, in 1998, through issue, by subsidiaries of the Company, of
bonds and preferred securities, the proceeds of which will be loaned to the
Company.
 
  The acquisition was accounted for using the purchase method of accounting in
accordance with Accounting Principles Board Opinion No. 16, "Accounting for
Business Combinations". The purchase price of YEG has been allocated to the
underlying assets and liabilities based on estimated fair values at the
acquisition date. The acquisition cost exceeded the fair market value of net
assets acquired by (Pounds)994 million ($1.630 billion), including (Pounds)17
million ($28 million) of acquisition related costs, and is considered
goodwill.
 
  The net purchase price of (Pounds)1.496 billion ($2.453 billion) was
allocated as follows at April 1, 1997 (in millions):

4. BUSINESS RESTRUCTURING CHARGES     
 
  On December 4, 1997, a planned business restructuring was announced. The
restructuring will result in the Company's main divisions (electricity
distribution and energy supply) becoming self-sufficient businesses. A
separate ownership structure will be pursued for the generation business. As a
result of the restructuring, approximately 160 positions within the head
office and corporate services division will no longer be required. The
estimated cost of this restructuring charged to operating expenses is
(Pounds)10 million ($16 million). As at December 31, 1997, the actual amount
of termination benefits paid was (Pounds)1 million ($2 million) relating to 4
employees.
 
5. SYSTEM DEVELOPMENT COSTS
 
  During the nine month period ended December 31, 1996, a (Pounds)24 million
($39 million) charge to earnings was recorded for costs incurred related to
information systems development costs pertaining to the opening up of the
competitive electricity market in 1998. It is management's opinion that, at
this stage in the development of the future commercial and regulatory
environment, it would not be prudent to capitalize these costs.
 
6. INTEREST RATE SWAPS
 
  As part of its risk management policy, the Company enters into interest rate
swap agreements under which counterparties have agreed to pay amounts to the
Company equal to variable interest obligations in consideration of amounts
payable by the Company equivalent to fixed rates of interest. If the
counterparty to the interest rate swap was to default on contractual payments,
the Company could be exposed to increased costs related to replacing the
original agreement. At December 31, 1997, the Company was party to interest
rate swap agreements with a notional value of (Pounds)650 million ($1.068
billion) which were at fixed interest rates varying between 7.13% and 7.50%.
Had the Company terminated its interest rate swap agreements on December 31,
1997, it would have incurred a loss of (Pounds)31 million ($51 million).
 
  In January 1998, the Company issued (Pounds)200 million ($329 million) of
7.25% Eurobonds which are due in 2028 and paid (Pounds)14 million ($23
million) to terminate interest rate swaps with a notional value of (Pounds)200
million ($329 million). The termination payments will be deferred and
amortized over the remaining life of the debt instruments being hedged.
 
  In February 1998, the Company issued $350 million aggregate principal amount
of 6.154% Senior Notes due 2003 and $300 million aggregate principal amount of
6.496% Senior Notes due 2008. Upon issuance of these notes, (Pounds)300
million of the above mentioned swaps and (Pounds)100 million new swap
agreements were consolidated with cross currency swaps to hedge the currency
exposure related to having sterling cash flows and dollar interest payments.
 
7. EXTRAORDINARY LOSS--WINDFALL TAX
 
  In July 1997, the British Government announced a "windfall tax" to be
applied at that date to companies privatized by floatation and regulated by
relevant privatization statutes. A decrease in the UK statutory income tax
rate from 33% to 31% was also included in the legislation. The Company
recorded an extraordinary loss of (Pounds)134 million ($220 million) for the
windfall tax and an income tax benefit as a result of the change in the UK
statutory income tax rate of approximately (Pounds)12 million ($20 million)
during the quarter ended September 1997. The windfall tax is not deductible
for UK corporation tax purposes and is payable in two equal instalments on or
before December 1, 1997 and 1998.

8. SUBSEQUENT EVENTS
 
  Following a profits warning issued by Ionica Group plc ("Ionica") in
November 1997, the fair value of the Company's investment in Ionica decreased
from (Pounds)54 million ($89 million) at April 1, 1997 to (Pounds)30 million
($49 million) at December 31, 1997 and an unrealized loss of (Pounds)18
million ($30 million), net of tax has been recorded. At April 30, 1998, the
fair value of the Company's investment in Ionica is valued at (Pounds)19
million ($31 million). This reduction of the fair value has not been included
as a charge against earnings as it is not considered that the diminution in
value is permanent.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Under English 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, default, breach of duty or breach of
trust 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
(whether civil or criminal), 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, default, or breach of duty or breach of trust where he has acted
honestly and reasonably and having regard to all the circumstances, 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.
 
  Subject to the general rule set out above, the Articles of Association of
Yorkshire Group provide that every director, other officer or auditor of
Yorkshire Group shall be indemnified out of the assets of Yorkshire Group
against any liability incurred by him in the actual or purported execution or
discharge of his duties or the exercise or purported exercise of his powers or
otherwise in relation to or in connection with his duties, powers or office.
This indemnity (i) shall not apply to any liability to the extent that it is
recovered from any other person and (ii) is subject to such officer or auditor
taking all reasonable steps to effect such recovery, so that the indemnity
shall not apply to the extent that an alternative right of recovery is capable
of being enforced.
 
  Pursuant to the Memorandum and Articles of Association of Yorkshire Finance,
the directors and officers for the time being of Yorkshire Finance and any
trustee for the time being acting in relation to any of the affairs of
Yorkshire Finance and their heirs, executors, administrators and personal
representatives respectively shall be indemnified out of the assets of
Yorkshire Finance from and against all actions, proceedings, costs, charges,
losses, damages and expenses which they or any of them shall or may incur or
sustain by reason of any act done or omitted in or about the execution of
their duty in their respective offices or trusts, except such (if any) as they
shall incur or sustain by or through their own wilful neglect or default
respectively and no such director, officer or trustee shall be answerable for
the acts, receipts, neglects or defaults of any other director, officer or
trustee or for joining in any receipt for the sake of conformity or for the
solvency or honesty of any banker or other persons with whom any monies or
effects belonging to Yorkshire Finance may be lodged or deposited for safe
custody or for any insufficiency of any security upon which any monies of
Yorkshire Finance may be invested or for any other loss or damage due to any
such cause as aforesaid or which may happen in or about the execution of his
 
                                     II-1

office or trust unless the same shall happen through the wilful neglect or
default of such director, officer or trustee.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
  Yorkshire Finance issued:
 
    (i) (Pounds)200 million ($338 million) aggregate principal amount of its
  7.25% Guaranteed Bonds due 2028 (the "Guaranteed Eurobonds") which were
  subscribed by Merrill Lynch International and UBS Limited (the "Managers").
  The Managers agreed to subscribe for the Guaranteed Eurobonds at 7.25% of
  their principal amount. Yorkshire Finance has agreed to pay the Managers a
  selling commission of 0.25% of the principal amount of the Guaranteed
  Eurobonds and a combined management and underwriting fee of 0.375% of such
  principal amount. The Guaranteed Eurobonds are not to be offered or sold
  within the US or to, or for the account or benefit of, US persons except in
  accordance with Regulation S or in certain transactions exempt from the
  registration requirements of the Securities Act.
 
    (ii) $350,000,000 aggregate principal amount of its 6.154% Senior Notes
  due 2003 and $300,000,000 aggregate principal amount of its 6.496% Senior
  Notes due 2008 to a group of initial purchasers led by Merrill Lynch,
  Pierce, Fenner & Smith Incorporated, Salomon Brothers Inc, J.P. Morgan
  Securities Inc., Morgan Stanley & Co. Incorporated and UBS Securities LLC
  (the "Initial Purchasers"). The net proceeds of such sale were $645,950,000
  , after deduction of the Initial Purchasers' discount (which was
  $4,050,000). The sale by Yorkshire Finance of such Notes to the Initial
  Purchasers was exempt from registration under the Securities Act of 1933
  pursuant to Section 4(2) thereof.

  (b) Financial Statement Schedules
 
  The following financial statement schedule is filed as part of this
Registration Statement:
 
Schedule II--Valuation and Qualifying Accounts.
 
ITEM 17. UNDERTAKINGS.
 
  The undersigned registrants hereby undertake:
 
    (1) That, for purposes of determining any liability under the Securities
  Act of 1933, the information omitted from the form of prospectus filed as
  part of this registration statement in reliance upon Rule 430A and
  contained in a form of prospectus filed by the registrants pursuant to Rule
  424(b) (1) or (4) under the Securities Act of 1933 shall be deemed to be
  part of this registration statement as of the time it was declared
  effective.
 
    (2) That, for the purpose of determining any liability under the
  Securities Act of 1933, each post-effective amendment that contains a form
  of prospectus shall be deemed to be a new registration statement relating
  to the securities offered herein, and the offering of such securities at
  that time shall be deemed to be the initial bona fide offering thereof.
 
    (3) To provide to the underwriters at the closing specified in the
  underwriting agreement certificates in such denominations and registered in
  such names as required by the underwriters to permit prompt delivery to
  each purchaser.
 
    (4) That, insofar as indemnification for liabilities arising under the
  Securities Act of 1933, may be permitted to directors, officers and
  controlling persons of the registrants pursuant to the foregoing
  provisions, or otherwise, the registrants have been advised that in the
  opinion of the Securities and Exchange Commission such indemnification is
  against public policy as expressed in the Securities Act of 1933 and is,
  therefore, unenforceable. In the event that a claim for indemnification
  against such liabilities (other than the payment by the registrants of
  expenses incurred or paid by a director, officer or controlling person of
  the registrants 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 registrants will,
  unless in the opinion of their counsel the matter has been settled by
  controlling precedent, submit to a court of appropriate jurisdiction the
  question whether such indemnification by them is against public policy as
  expressed in the Securities Act of 1933 and will be governed by the final
  adjudication of such issue.

Ladies and Gentlemen:

     We are acting as United States counsel to Yorkshire Power Group Limited
("Yorkshire") and Yorkshire Power Finance Limited ("Yorkshire Finance") 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 March 13, 1998 (the "Registration Statement"),
contemplating the registration under the Securities Act of 1933, as amended (the
"Act"), of (1) Junior Subordinated Deferrable Interest Debentures (the "Junior
Subordinated Debentures") to be issued by Yorkshire Finance to Yorkshire Capital
Trust I (the "Trust"), (2) Trust Securities (liquidation amount $25 per Trust
Security) to be issued by the Trust, (3) Yorkshire's Trust Securities Guarantee
(as defined in the Registration Statement) with respect to such Trust Securities
and (4) Yorkshire's Debentures Guarantee (as defined in the Registration
Statement) with respect to the Junior Subordinated Debentures. The Junior
Subordinated Debentures and the Debentures Guarantee will be issued pursuant to
a subordinated indenture, as supplemented, among Yorkshire, Yorkshire Finance,
and the trustee named therein (the "Subordinated Indenture") and the Trust
Securities Guarantee will be issued pursuant to a guarantee agreement between
Yorkshire and the trustee named therein (the "Trust Securities Guarantee
Agreement"), in each case in the respective forms filed as exhibits to the
Registration Statement.

     We are of the opinion that, upon compliance with the pertinent provisions
of the Act, the Trust Indenture Act of 1939, as amended, and the Public Utility
Holding Company Act of 1935, as amended, upon compliance with applicable
securities or blue sky laws of various jurisdictions, upon the adoption of
appropriate resolutions by each of the Directors of Yorkshire Finance or a duly
authorized committee thereof and the

Directors of Yorkshire or a duly authorized committee thereof, when the
Subordinated Indenture has been duly executed and delivered by the proper
officers of Yorkshire, Yorkshire Finance and the trustee named therein, when the
Trust Securities Guarantee Agreement has been duly executed and delivered by the
proper officers of Yorkshire and the trustee named therein, and when the Junior
Subordinated Debentures, the Debentures Guarantee and the Trust Securities
Guarantee have been executed, authenticated and delivered in accordance with the
terms of the Subordinated Indenture and the Trust Securities Guarantee
Agreement, as the case may be, (i) the Debentures Guarantee and the Trust
Securities Guarantee will be valid, binding and legal obligations of Yorkshire
(subject to applicable bankruptcy, insolvency, reorganization, moratorium and
other similar laws relating to or affecting creditors' rights generally and to
general principles of equity, whether considered in a proceeding at law or in
equity) and (ii) the Junior Subordinated Debentures will be valid, binding and
legal obligations of Yorkshire Finance (subject to applicable bankruptcy,
insolvency, reorganization, moratorium and other similar laws relating to or
affecting creditors' rights generally and to general principles of equity,
whether considered in a proceeding at law or in equity).
    
     We are members of the State Bar of New York and we do not express any
opinion herein concerning any law other than the law of the State of New York,
the federal law of the United States. In rendering the opinion expressed in
clause (ii) immediately above with respect to the validity of the Junior
Subordinated Debentures, we have relied upon the opinion address to you and
dated the date hereof of Maples and Calder as to matters of Cayman Islands law. 
We hereby consent to the reliance by Maples and Calder on the opinions 
expressed herein insofar as such opinions relate to matters of New York 
law.     

     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 Opinions" in the Registration Statement. In giving the foregoing

Dear Sirs:


RE:      REGISTRATION STATEMENT ON FORM S-1
- ---      ----------------------------------

    
We are Cayman Islands Counsel to Yorkshire Power Finance Limited ("Yorkshire
Finance") in connection with the preparation of a registration statement on Form
S-1, including a preliminary prospectus, filed with the United States Securities
and Exchange Commission (the "Commission") on 13th March, 1998 (the
"Registration Statement"), contemplating the registration under the United
States Securities Act of 1933, as amended (the "Securities Act"), of Junior
Subordinated Deferrable Interest Debentures (the "Junior Subordinated
Debentures") to be issued by Yorkshire Finance and guaranteed by Yorkshire Power
Group Limited ("Yorkshire") and subscribed by Yorkshire Capital I. The Junior
Subordinated Debentures will be issued pursuant to a subordinated indenture, as
supplemented, to be entered into between Yorkshire Finance, Yorkshire and the
trustee named therein (the "Subordinated Indenture") in substantially the form
filed as an exhibit to the Registration Statement.     

For the purposes of this opinion, we have reviewed the Companies Law (1995
Revision) of the Cayman Islands (the "Companies Law") and have examined and
relied upon:

1. the prospectus relating to the Junior Subordinated Debentures in the form
   included in the Registration Statement;
 
2. the Memorandum and Articles of Association of Yorkshire Finance;
    
3. Certificate of Incorporation and Certificate of Incorporation on Change of 
   Name of Yorkshire Finance;     
 
4. the form of the Subordinated Indenture;
 
5. the Minutes of a Meeting of the Board of Directors of Yorkshire Finance held
   on 11th February, 1998 (the "Minutes"), the Power of Attorney granted by the
   Company on 11th February, 1998 and the corporate records of Yorkshire
   Finance; and

6.  a Certificate from a Director of Yorkshire Finance in the form annexed
    hereto (the "Director's Certificate") and     
    
7.  the opinion dated the date hereof and given by Dewey Ballantine LLP, United 
    States counsel to Yorkshire Finance and Yorkshire (the "Dewey Ballantine 
    Opinion")     
    
The following opinion is given only as to circumstances existing on the date
hereof and known to us and as to the laws of the Cayman Islands as the same are
in force at the date hereof.  In giving this opinion, we have relied upon the
accuracy of the Director's Certificate and the Dewey Ballantine Opinion on the 
date of issue hereof without further verification and have relied upon the
following assumptions, which we have not independently verified:-      

    
(a)  The Junior Subordinated Debentures and the Subordinated Indenture will be
     duly authorised, executed and delivered by or on behalf of all relevant
     parties (other than Yorkshire Finance);     

(b)  The choice of the laws of the State of New York as the governing law of the
     Junior Subordinated Debentures and the Subordinated Indenture will be made
     in good faith and would be regarded as a valid and binding selection which
     will be upheld by the courts of the State of New York as a matter of New
     York  law and all other relevant courts (other than the courts of the
     Cayman Islands);

(c)  Copy documents or the forms of documents provided to us are true copies of,
     or in the final forms of, the originals;

(d)  The genuineness of all signatures;

(e)  The power, authority and legal right of all parties under all relevant laws
     and regulations (other than Yorkshire Finance under the laws of the Cayman
     Islands) to execute and perform their respective obligations under the
     Junior Subordinated Debentures and the Subordinated Indenture;

(f)  The Junior Subordinated Debentures will be duly completed, executed and
     authenticated and delivered in accordance with, and as contemplated by, the
     provisions of the Subordinated Indenture;

(g)  That all preconditions to the obligations of the parties to the Junior
     Subordinated Debentures and the Subordinated Indenture have been or will be
     satisfied or duly waived and there has been no breach of the terms of the
     Junior Subordinated Debentures or the Subordinated Indenture; and

Re:  Registration Statement
- --------------------------------------------------------------------------------


(h)  There is nothing under any law (other than the laws of the Cayman Islands)
     which would or might affect the opinions hereinafter appearing.
     Specifically, we have made no independent investigation of the laws of the
     State of New York.


We render no opinion as to the negotiability or transferability by delivery of
any Junior Subordinated Debentures in any jurisdiction which does not recognise
such negotiability or transferability.

Based upon and subject to the foregoing and having regard to such legal
considerations as we deem relevant, we are of the opinion that:-

1.  Yorkshire Finance has been duly incorporated and is validly existing under
    the laws of the Cayman Islands;
 
2.  Assuming that the precise terms of issue of the Junior Subordinated
    Debentures are duly determined by an Attorney of the Company in accordance
    with the resolutions set forth in the Minutes, the Subordinated Debentures
    have been duly authorised by Yorkshire Finance and, when executed on behalf
    of Yorkshire Finance, authenticated in the manner set forth in the Junior
    Subordinated Indenture and delivered against due payment therefor, will
    constitute the legal, valid and binding obligations of Yorkshire Finance
    enforceable in accordance with their terms, except and insofar as such
    enforcement may be limited as hereinafter set forth. The term "enforceable"
    as used above means the obligations assumed by Yorkshire Finance under the
    Junior Subordinated Debentures are of a type which the Courts of the Cayman
    Islands enforce. It does not mean those obligations will necessarily be
    enforced in all circumstances in accordance with their terms and we would
    draw to your attention:

(i)     enforcement may be limited by bankruptcy, insolvency, liquidation,
        reorganization and other laws of general application relating to or
        affecting the rights of creditors;

(ii)    enforcement may be limited by general principles of equity - for
        example, equitable remedies such as specific performance may not be
        available, inter alia, where damages are considered to be an adequate
        remedy;

(iii)   claims may become barred under the statutes of limitation or may be or
        become subject to defences of set-off or counterclaim;

(iv)    where obligations are to be performed in a jurisdiction outside the
        Cayman Islands, they may not be enforceable in the Cayman Islands to the
        extent that performance would be illegal under the laws of that
        jurisdiction;

(v)     in the event of any proceedings being brought in the Cayman Islands
        courts in respect of a monetary obligation expressed to be payable in a
        currency other than Cayman

Re:  Registration Statement
- --------------------------------------------------------------------------------

        Islands dollars, a Cayman Islands court will give judgement expressed as
        an order to pay such other currency on enforcement of the judgement.
        With respect to winding up proceedings, Cayman Islands law will require
        that all claims or debts are converted into Yorkshire Finance's
        functional currency of account;

(vi)    Cayman Islands stamp duty will be payable if any of the Junior
        Subordinated Debentures or the Subordinated Indenture is brought to or
        executed in the Cayman Islands, which duty would be up to CI$250 on each
        of the Junior Subordinated Debentures (unless Yorkshire Finance has paid
        a duty of CI$500 in respect of the issue of the Junior Subordinated
        Debentures) and would be CI$40 on the Subordinated Indenture;

(vii)   a certificate, determination, calculation or designation of any party to
        the foregoing documents as to any matter provided therein might be held
        by a Cayman Islands court not to be conclusive, final and binding if,
        for example, it could be shown to have an unreasonable or arbitrary
        basis or in the event of manifest error;

(viii)  although there is no statutory enforcement in the Cayman Islands of
        judgments obtained in New York, the courts of the Cayman Islands will
        recognise and enforce a foreign judgment of a court of competent
        jurisdiction without reexamination or relitigation of the matter
        adjudicated upon, based on the principle that a judgment of a competent
        foreign court imposes upon the judgment debtor an obligation to pay the
        sum for which judgment has been given, and provided such judgment is
        final, for a liquidated sum not in respect of taxes or a fine or
        penalty, and which was not obtained in a manner, and is not of a kind
        the enforcement of which is, contrary to the public policy of the Cayman
        Islands; a Cayman Islands court may stay proceedings if concurrent
        proceedings are being brought elsewhere;

(ix)    obligations to make payments that may be regarded as penalties will not
        be enforceable to the extent that they are penal;

(x)     in principle a Cayman Islands court will award costs and disbursements
        in litigation in accordance with contractual provisions in this regard
        but the applicable rule of court (GCR Order 62, rule 2) has been in
        force only since 1st June, 1995 and there remains some uncertainty as to
        the way in which it will be applicable in practice. Whilst it is clear
        that costs incurred prior to judgement can be recovered in accordance
        with the contract, it is likely that post-judgment costs will be
        recoverable, if at all, in accordance with the scales laid down in the
        Grand Court (Taxation of Costs) Rules 1995;

(xi)    we reserve our opinion as to the extent to which a Cayman Islands court
        would, in the event of any relevant illegality, sever the offending
        provisions and enforce the remainder of the transaction of which such
        provisions form a part, notwithstanding any express provisions in this
        regard;

Re:  Registration Statement
- --------------------------------------------------------------------------------

(xii)  to maintain Yorkshire Finance in good standing under the laws of the
       Cayman Islands, annual filing fees must be paid and Returns made to the
       Registrar of Companies;

(xiii) the obligations of Yorkshire Finance under the Junior Subordinated
       Debentures or the Subordinated Indenture which involve the government of
       any country which is currently the subject of United Nations sanctions as
       extended to the Cayman Islands by an Order in Council (namely Iraq and
       Libya and each an "Affected Country"), any person or body resident in,
       incorporated in or constituted under the laws of any Affected Country or
       exercising public functions in any Affected Country or any person or body
       controlled by any of the foregoing or by any person acting on behalf of
       any of the foregoing may be subject to restrictions pursuant to such
       sanctions as implemented under the laws of the Cayman Islands;

(xiv)  if Yorkshire Finance obtains a beneficial interest in any of the Junior
       Subordinated Debentures then its rights and obligations in respect
       thereof may merge thus extinguishing its rights and obligations in
       respect thereof, so that any attempted resale of those Junior
       Subordinated Debentures might constitute a separate issue of debt
       obligations;

(xvi)  we make no comment with regard to the references to foreign statutes in
       the Junior Subordinated Debentures or the Subordinated Indenture.
    
This opinion is for the benefit of the addressees but may be relied upon
by the addressees' legal advisors (in that capacity only). We hereby consent to
the filing of this opinion as an exhibit to the Registration Statement and to
the reference to us under the heading "Legal Opinions" in the prospectus
included in the Registration Statement. In giving such consent, we do not
thereby admit that we are in the category of persons whose consent is required
under Section 7 of the Securities Act or the rules or regulations of the
Commission thereunder.

              the date of this certificate."

3.       The Licensee shall submit to the Director with that certificate a
         statement of the main factors which the directors of the Licensee have
         taken into account in giving that certificate.

4.       The Licensee shall inform the Director in writing immediately if the
         directors of the Licensee become aware of any circumstance which causes
         them no longer to have the reasonable expectation expressed in the then
         most recent certificate given under paragraph 2.

5.       The Licensee shall use its best endeavours to obtain and submit to the
         Director with each certificate provided for in paragraph 2 a report
         prepared by its auditors and addressed to the Director stating whether
         or not the auditors are aware of any inconsistencies between, on the
         one hand, that certificate and the statement submitted with it and, on
         the other hand, any information which they obtained during their audit
         work.

6.       The Licensee shall procure from the holding company of the Licensee a
         legally enforceable undertaking in favour of the Licensee in a form
         already specified by the Director that the holding company will refrain
         from any action, and will procure that every subsidiary of the holding
         company (other than the Licensee and its subsidiaries) will refrain
         from any action, which would then be likely to cause the licensee to
         breach any of its obligations under the Act or this Licence. Such
         undertaking shall be obtained by 22 December 1997 and shall remain in
         force for as long as the Licensee remains the holder of this Licence
         and the giver of the undertaking remains the holding company of the
         Licensee.

                  obligation to procure an undertaking pursuant to paragraph 6;

         (b)      inform the Director immediately in writing if the directors of

CONDITION 3A:  RESTRICTION OF DISTRIBUTION CHARGES
- --------------------------------------------------

BASIC FORMULA
- -------------

1.   Without prejudice to Condition 3F the Licensee shall in setting its charges
     for the provision of distribution services use its best endeavours to
     ensure that in any relevant year the average charge per unit distributed
     shall not exceed the maximum average charge per unit distributed calculated
     in accordance with the following formula:

                        M/dt/ = P/dt/ + PN/dt/ - K/dt/

2.   For the purposes of paragraph 1, M/dt/ means the maximum average charge per
     unit distributed in relevant year t.

     Formula for P/dt/ as used in paragraph 1
     ----------------------------------------

3.   For the purposes of paragraph 1, P/dt/ is derived from the following
     formula:

            P/dt/ = (  (PU+PM) . GR/t/..PID /t/) + (PL. (Al/t/ - L/t/) . PIL/t/)
                        -----------------------------------------------
                                      D/t/

     where:

            PU      means the amount set against that term in the part of Annex
                    A to this Condition that applies to the Licensee.

            PM      means the amount set against that term in the part of Annex
                    A to this Condition that applies to the Licensee.

            GR/t/   is derived from the following formula:
                                   
                                        
                    GR/t/ = 0.5    (SIGMA)P/oi/.D/it/  + Cd/t/ ) GR/t/ -1

          D/it/     means that number of units in each regulated distribution
                    unit category i distributed in relevant year t.

          D/it/-1   means that number of units in each regulated distribution
                    unit category i distributed in relevant year t-1.

          C/dt/     means a notional figure, representing the number of
                    customers in the authorised area defined (for the purpose of

                    paragraph E5 of Part E of Schedule 3) where in respect of
                    each relevant year t, the allowed percentage shall equal
                    that percentage which the aggregate of adjusted distribution
                    losses (calculated as provided in paragraphs E2 to E5 of
                    Part E of Schedule 3) over the preceding relevant years
                    (commencing with the twelve-month period from 1 April 1989,
                    or, if the number of preceding relevant years exceeds nine,
                    relevant year t-10) bears to the aggregate of adjusted units
                    distributed (calculated as aforesaid) over the corresponding
                    relevant years: save that for this purpose adjusted
                    distribution losses in respect of the twelve-month period
                    from 1 April 1989 shall be derived by applying the initial

1.1  Save where the Director consents in writing to a tariff being discontinued,
     the Licensee shall continue to make available to customers at Designated
     Premises the tariffs listed under the Licensee's name in Annex A to this
     Condition.

1.2  Where a customer at Designated Premises was supplied at the end of the
     eighth relevant year on a tariff listed under the Licensee's name in Annex
     B to this Condition, the Licensee shall continue to offer that tariff to
     that customer at those premises unless the Director consents in writing to
     the Licensee's not doing so.

1.3  The Licensee shall not, without the consent in writing of the Director,
     change the terms (other than price, which shall be regulated in accordance
     with this Condition) of any tariff described in the second column of the

                                       51
<PAGE>
 
     Table which is a domestic prepayment tariff,

     (a)  the standing charge and the unit charge at the beginning of the ninth
          relevant year shall each be lower than the standing charge and unit
          charge respectively set against that tariff in column 5 of the Table
          by the same proportion as the standing charge and the unit charge at
          the beginning of the ninth relevant year of the nearest equivalent
          domestic tariff (not being a prepayment tariff) are lower than the
          standing charge and unit charge respectively of that nearest
          equivalent domestic charge shown against them in column 5 of the Table
          (and in this sub-paragraph the standing charge shall be exclusive of
          any prepayment surcharge); and

     (b)  there shall at no time be any increase in the amount by which the
          standing charge (including any prepayment meter surcharge) for any
          domestic prepayment tariff exceeds the standing charge for the nearest
          comparable domestic tariff (not being a prepayment tariff).

7.2  The Director may direct which tariff is the nearest equivalent domestic
     tariff for the purpose of this paragraph.

8.1  Without prejudice to paragraph 9 and Condition 3F, no price (whether a
     standing charge or a unit charge) in any tariff shall be increased during
     the ninth relevant year above the price which applies at the beginning of
     the ninth relevant year, unless the Director has consented in writing.

8.2  In giving consent the Director shall have regard in particular but not
     exclusively to the impact of significant movements in costs outside the
     Licensee's control, and shall consider whether such movements in costs
     justify an increase in all tariffs, a differential increase in tariffs or
     an increase in some tariffs only.

9.   If any change is made to the rate of the Fossil Fuel Levy between 1 August
     1997 and 2 April 1998, and whenever any change is made to that rate
     thereafter, every price limit set pursuant to paragraphs 4, 5, 6 and 7.1(a)
     shall be multiplied by the following factor:

                         100 + F/t/

10.1  Where, after the end of the eighth relevant year, the Director is
      satisfied that in the eighth relevant year the average charge per unit
      supplied differed from the maximum average charge per unit supplied
      assumed for the purpose of setting the prices in column 5 of the Table,
      the Director may give a direction to the Licensee stipulating the prices
      to be charged for any (or all) of the tariffs described in column 2 of the
      Table.

10.2  Before giving any such direction, the Director shall consult the Licensee.

10.3  In considering whether to give any such direction, and in considering the
      content of any such direction, the Director shall have regard

      (a)  to the extent to which the regulated supply revenue for the eighth
           relevant year assumed for the purpose of setting the prices in column
           5 of the Table differs from the actual regulated supply revenue for
           that year adjusted

           (i)  to reflect what the regulated supply revenue would have been if
           the tariffs in force on 1 August 1997 had remained unchanged until
           the end of the eighth relevant year; and

           (ii) by adding any rebates or discounts to Regulated Customers in
           respect of the period from 1 August 1997 to the end of the eighth
           relevant year, being rebates or discounts not included in the tariffs
           in force on 1 August 1997;

      (b)  to any representations made by the Licensee; and

      (c)  to the cost to the Licensee of changing any tariff.

11.1  Where, for relevant year t, the terms TAdt or GAdt (or both of them) in
      paragraph 4 of Condition 3A have a value greater than 0, the Director may
      give a direction to the Licensee stipulating the prices to be charged, in
      that or any subsequent relevant year, for any (or all) of the tariffs
      described in column 2 of the Table.

11.2  Before giving any such direction, the Director shall consult the Licensee.

                                       53
<PAGE>
 
11.3   In considering whether to give any such direction, and in considering the
       content of any such direction, the Director shall have regard

       (a)   to the extent by which the charges made by the Distribution
             Business to the Supply Business have been reduced on account of the
             terms TA/dt/ or GA/dt/ (or both of them) having a greater value
             than 0;

       (b)   to any representation made by the Licensee; and

       (c)   to the cost to the Licensee of changing any tariff.

12.1   Without prejudice to paragraph 9 and Condition 3F, for the tenth and
       every subsequent relevant year, unless the Director has consented in
       writing, each component of each tariff described in column 2 of the Table
       or approved for the purpose of paragraph 2 shall have a price no greater
       than the price at the end of the immediately preceding relevant year, in
       each case multiplied by the formula

                        100 + RPIt - Xc                         
                       -----------------
                             100

       where X/c/ has the value of 3 for the tenth relevant year and the value
       of 0 for every subsequent relevant year.

12.2   In giving consent the Director shall have regard in particular but not
       exclusively to the impact of significant movements in costs outside the
       Licensee's control, and shall consider whether such movements in costs
       justify an increase in all tariffs, a differential increase in tariffs or
       an increase in some tariffs only.

CONDITION 3D:  RESTRICTION OF DISTRIBUTION CHARGES AND OF SUPPLY CHARGES:
- -------------------------------------------------------------------------
ADJUSTMENTS
- -----------

1.   If, in respect of any relevant year, the average charge per unit
     distributed exceeds the maximum average charge per unit distributed by more
     than 3 per cent, the Licensee shall furnish an explanation to the Director
     and in the next following relevant year the Licensee shall not effect any
     increase in charges unless it has demonstrated to the reasonable
     satisfaction of the Director that the average charge per unit distributed
     would not be likely to exceed the maximum charge per unit distributed in
     that next following relevant year.

2.   If, in respect of any two successive relevant years, the sum of the amounts
     by which the average charge per unit distributed has exceeded the maximum
     average charge per unit distributed is more than 4 per cent, then in the
     next following relevant year the Licensee shall, if required by the
     Director, adjust its charges such that the average charge per unit
     distributed would not be likely, in the judgment of the Director, to exceed
     the maximum average charge per unit in that next following relevant year.

3.   If, in respect of two successive relevant years, the average charge per
     unit distributed is less than 90 per cent of the maximum average charge per
     unit distributed, the Director, after consultation with the Licensee, may
     direct that in calculating K/dt/ for the purposes of paragraph 1 of
     Condition 3A in respect of the next following relevant year, there shall be
     substituted for R/dt-1/ in the formula at paragraph 1 of Condition 3A such
     figure as the Director may specify being not less than R/dt-1/, and not
     more than 0.90 (Dt-1.M/dt-1/).

4.1  If, in respect of the eighth relevant year, the average charge per
     regulated unit supplied exceeds the maximum average charge per regulated
     unit supplied, but by not more than 1 1/2 per cent, the Licensee shall
     ensure that the excess above the maximum average charge per regulated unit
     supplied, with interest thereon at a rate 2 per cent above the average
     specified rate, shall be paid to all 0.1 MW customers who continue to be
     supplied by the Licensee in the ninth relevant year.

4.2  If, in respect of the eighth relevant year, the average charge per
     regulated unit supplied exceeds the maximum average charge per regulated
     unit supplied by more than 1 1/2 per cent, the Licensee shall use all
     reasonable endeavours to return the excess above the maximum average charge
     per unit supplied, with interest thereon at a rate 4 per cent above the
     average specified rate, during the ninth relevant year to all 0.1MW
     customers supplied by the 

                                       62
<PAGE>
 
     Licensee in the eighth relevant year.

4.3  For the purpose of Condition 3B, no sum payable under paragraphs 4.1 or 4.2
     shall be regarded as paid or payable under a tariff applicable to the ninth
     relevant year or any subsequent relevant year.

5.   No later than three months after the end of the eighth relevant year, the
     Licensee shall send to the Director a statement accompanied by such
     forecasts, estimates and calculations as may be necessary, showing the
     basis by which the Licensee intends to comply with paragraph 4.

6.   The powers exercisable under paragraphs F6 and F8 of Part F of Schedule 3
     in the form of licence in force on 31 March 1998 shall continue to be
     exercisable after that date, but only in respect of a relevant year ending
     before 1 April 1998.

CONDITION 3E:  INFORMATION TO BE PROVIDED TO THE DIRECTOR IN CONNECTION WITH THE
- --------------------------------------------------------------------------------
CHARGE RESTRICTION CONDITIONS
- -----------------------------

1.   Where the Licensee is intending to make any change in charges for the
     provision of distribution services regulated under Condition 3A the
     Licensee shall (unless otherwise agreed by the Director) not later than the
     date of publication of such charges provide the Director with:

     (a)  written forecast of the maximum average charge per unit distributed,
          together with its components, in respect of the relevant year t in
          which such a change is to take effect and in respect of the next
          following relevant year t+1; and

     (b)  a written estimate of the maximum average charge per unit distributed,
          together with its components, in respect of the relevant year t-1
          immediately preceding the relevant year in which the change is to take
          effect unless a statement complying with paragraph 7 in respect of
          relevant year t-1 has been furnished to the Director before the
          publication of the proposed change.

2.   Where, at any time during the eighth relevant year, the Licensee intends to
     change the principles of attribution or any provisional attribution
     specified in a statement already made to the Director or to purchase or
     sell an electricity sale contract, the change or the provisional
     attribution in relation to the purchase or sale shall be specified in a
     written statement signed by a person authorised to sign the statement by
     the directors of the Licensee which statement shall not provide for a
     retrospective change of principles or for any re-attribution of payments
     already made or any payment where the event giving rise to that payment has
     already occurred.

3.   If within three months of the commencement of any relevant year t the
     Licensee has not made any such change in charges as is referred to in
     paragraph 1, the Licensee shall provide the Director with a written
     forecast of the maximum average charge per unit distributed, together with
     its components, in respect of the relevant year t.

                                       64

4.   The Director may issue directions providing that any forecast or estimate
     provided in accordance with paragraphs 1, 2 or 3 shall be accompanied by
     such information as regards the assumptions underlying the forecast or
     estimate as may be necessary to enable the Director to be satisfied that

5.   Subject as provided in sub-paragraph (b) below, not later than six weeks
     after the commencement of each relevant year t, the Licensee shall send to
     the Director a statement as to:

     (a)  whether or not the provisions of Condition 3D are likely to be
          applicable in consequence of the average charge per unit distributed
          in the preceding relevant year t-1 or the two preceding relevant years
          t-1 and t-2; and

     (b)  its best estimate as to the relevant correction factor K/dt/ to be
          applied in calculating the maximum average charge per unit distributed

6.   Not later than 15 January in the ninth and tenth relevant years the
     Licensee shall send to the Director a written estimate of the value of the
     term TA for that year (TA/dt/), together with an estimate of the value of
     each of its component parts, as detailed in paragraph 4 of Condition 3A.

7.   Not later than three months after the end of a relevant year the Licensee
     shall send the Director a statement, in respect of that relevant year,

          restriction conditions and (ii) the amounts shown in respect of each
          of those specified items are in accordance with the Licensee's

          (i)    there is no amount included in its calculations under Condition
                 3A and Schedule 3 which represents other than:

                 (bb) an amount permitted under the charge restriction

                 be so included;

          (iv)   no service has been treated as an excluded service which was
                 not properly so treated and no amount included in the revenues
                 in respect thereof represents other than bona fide

CONDITION 3F:  ALLOWANCES IN RESPECT OF SECURITY COSTS
- ------------------------------------------------------

1.   At any time during a security period, the Licensee may give notice in
     writing to the Director suspending, with effect from the date of receipt of
     the notice by the Director, application of such of the charge restriction
     conditions as may be specified in the notice for the unexpired term of the
     security period.

2.   At any time during a security period, the Director may (having regard to
     his duties under the Act) by means of directions:

     (a)    suspend or modify for the unexpired term of the security period the
            charge restriction conditions or any part or parts thereof; or

     (b)    introduce for the unexpired term of the security period new charge
            restriction conditions

     in either case, so as to make such provision as in the opinion or
     estimation of the Director is requisite or appropriate:

     (i)    to enable the Licensee to recover by means of increased charges an
            amount estimated as being equal to the Licensee's allowed security
            costs during such period;

     (ii)   to ensure that such part of the amount referred to in sub-paragraph
            (i) above as is estimated as being equal to the allowed security
            costs incurred by the Licensee as costs in its Distribution Business
            are recovered by means of appropriate equitable increases on the
            charges made by the Licensee in its Distribution Business; and

     (iii)  to ensure that such part of the amount referred to in sub-paragraph
            (i) above as is estimated as being equal to the allowed security
            costs incurred by the Licensee as costs in its Supply Business and
            its Second-Tier Supply Business respectively are recovered by
            appropriate equitable increases in the charges made by the Licensee
            in those Businesses and the Licensee shall comply with the terms of
            any directions so issued.

                                       69
<PAGE>
 
3.   At any time following a security period, the Director may (following such
     consultation with the Licensee and others as the Director may consider
     appropriate) issue directions suspending or modifying the charge
     restriction conditions or any part or parts thereof or replacing such
     directions as may have been made during the security period and introducing
     such new charge restriction conditions as in the opinion of the Director
     are appropriate in all the circumstances (including at the Director's
     discretion an appropriate adjustment having regard to any profit gained or
     forgone by the Licensee during the security period), and the Licensee shall
     comply with any directions so issued.

4.   At any time within three months after the issue of directions by the
     Director under paragraph 3, the Licensee may serve on the Director a
     disapplication request in respect of such of the charge restriction
     conditions or any part or parts thereof as are specified in the request.

5.   If within three months of the receipt by the Director of the disapplication
     request referred to in paragraph 4, the Director has either not agreed in
     writing to such disapplication request or has not made a reference to the
     Monopolies Commission under Section 12 of the Act relating to the
     modification of the charge restriction conditions, the Licensee may deliver
     one month's written notice to the Director terminating the application of
     the charge restriction conditions (or any part or parts thereof) as were
     specified in the disapplication request.

6.   Subject to paragraphs 7 and 9, the Licensee shall in any relevant year be
     entitled to recover an aggregate amount equal to its allowed security costs
     in that year or (insofar as not previously recovered) any previous year, by
     means of appropriate equitable increases on the charges made by the
     Licensee in each of its Distribution, Supply and Second-Tier Supply
     Businesses.

7.   Paragraph 6 shall not apply insofar as such allowed security costs:

     (a)   were otherwise recovered by the Licensee; or

     (b)   were taken into account by the Director in setting charge restriction
           conditions by means of directions issued under paragraph 3 above.

                                       70

8.   The Licensee shall following the end of each relevant year provide to the
     Director, as being one of the specified items to be contained in the
     statement referred to at paragraph 8 of Condition 3E, details in respect of
     that relevant year of:

     (a)   the amount of the Licensee's allowed security costs; and

     (b)   the aggregate amounts charged under paragraph 6 on account of the
           Licensee's allowed security costs; and
        
     (c)   the bases and calculations underlying the increases in charges made
           by the Licensee in its Distribution, Supply and Second-Tier Supply
           Businesses under paragraph 6.

9.   Where the Director is satisfied that the Licensee has recovered amounts in
     excess of the allowed security costs, the Director may issue directions
     requiring the Licensee to take such steps as may be specified to reimburse
     customers of or purchasers from the Distribution, Supply and Second-Tier
     Supply Business (as the case may be) for the excess amounts charged to
     them, and the Licensee shall comply with any directions so issued provided
     that if the excess amounts relate to allowed security costs paid to any
     authorised electricity operator, the Licensee shall not be obliged to make
     any such reimbursement unless and until it has recovered such costs from
     the relevant authorised electricity operator.

10.  No amounts charged by the Licensee under this Condition (whether or not
     subsequently required to be reimbursed) shall be taken into account for the
     purpose of applying the charge restriction provisions of Conditions 3A and
     3B.

                            terminating on the date (being not earlier than the
                            date such direction, as varied, is revoked or
                            expires) as the Director, after consultation with
                            such persons (including without limitation, Licence
                            holders liable to be principally affected) as he
                            shall consider appropriate, may with the consent of
                            the Secretary of State by notice to all Licence
                            holders determine after having regard to the views
                            of such persons.

CONDITION 3G:  DURATION OF CHARGE RESTRICTION CONDITIONS
- --------------------------------------------------------

1.   The charge restriction conditions shall apply so long as this Licence
     continues in force but shall cease to have effect (in whole or in part, as
     the case may be) if the Licensee delivers to the Director a disapplication
     request made in accordance with paragraph 2 and:

     (a)  the Director agrees in writing to the disapplication request; or

     (b)  their application (in whole or in part) is terminated by notice given

2.   A disapplication request pursuant to this Condition 3G shall (a) be in
     writing addressed to the Director, (b) specify the charge restriction
     conditions (or any part or parts thereof) to which the request relates and
     (c) state the date from which the Licensee wishes the Director to agree
     that the specified charge restriction conditions shall cease to have
     effect.

3.   Save where the Director otherwise agrees, no disapplication following
     delivery of a disapplication request pursuant to this Condition 3G shall
     have effect earlier than that date which is the later of:

     (a)  a date being not less than 18 months after delivery of the
          disapplication request; and either

     (b)  in the case of distribution charges regulated under Condition 3A, 31st

                                       73
<PAGE>
 
4.   If the Director has not made a reference to the Monopolies Commission under
     Section 12 of the Act relating to the modification of the charge
     restriction conditions before the beginning of the period of 12 months
     which will end with the disapplication date, the Licensee may deliver
     written notice to the Director terminating the application of such of the
     charge restriction conditions (or any part or parts thereof) as are
     specified in the disapplication request with effect from the disapplication
     date or a later date.

5.   If the Monopolies Commission makes a report on a reference made by the
     Director relating to the modification of the charge restriction conditions
     (or any part or parts thereof) specified in the disapplication request and
     such report does not include a conclusion that the cessation of such charge
     restriction conditions, in whole or in part, operates or may be expected to
     operate against the public interest, the Licensee may within 30 days after
     the publication of the report by the Director in accordance with Section 13
     of the Act deliver to him written notice terminating the application of
     such charge restriction conditions with effect from the disapplication date
     or later.

CONDITION 4:   PROHIBITION OF CROSS-SUBSIDIES AND OF DISCRIMINATION IN
- ----------------------------------------------------------------------
ELECTRICITY SALE CONTRACTS
- --------------------------


1.   The Licensee shall procure that no Separate Business gives any cross-
     subsidy to, or receives any cross-subsidy from, any other business of the
     Licensee or an affiliate or related undertaking of the Licensee (whether or
     not a Separate Business).

2.   The Licensee shall not, and shall procure that any affiliate or related
     undertaking of the Licensee shall not, sell or offer to sell electricity
     under any electricity sale contract to any one relevant purchaser or person
     seeking to become a relevant purchaser on terms as to price which are
     materially more or less favourable than those on which it sells or offers
     to sell electricity under any electricity sale contract to comparable
     relevant purchasers. For these purposes, due regard shall be had to the
     circumstances of sale to such purchasers including (without limitation)
     volumes, load factors, conditions of interruptibility and the dates and
     duration of the relevant agreements.

3.   For the purposes of paragraph 2:

                                        electricity purchase contract.

CONDITION 4A:  PROHIBITION OF DISCRIMINATION IN SUPPLY
- ------------------------------------------------------


1.   This Condition applies where the Licensee is in a dominant position in a
     market for the supply of electricity to customers at premises.

2.   Where this Condition applies the Licensee shall not supply or offer to
     supply electricity to customers in any market in which it is dominant on
     terms which are predatory.

3.   Where this Condition applies, but subject to paragraph 4, the Licensee
     (taken together with its affiliates and related undertakings) shall not, in
     supplying or offering terms for the supply of electricity to customers in
     any market in which it is dominant:

     (a)  show undue preference to any person (or class of persons) within such
          market;

     (b)  exercise undue discrimination between any persons (or classes of
          person) within such market; or

     (c)  set terms which are unduly onerous.


4.   Nothing in paragraph 3 shall prohibit the Licensee, within any area or
     class of customers (the "relevant area or class") in respect of which there
     is established competition in the supply of electricity, from supplying or
     offering to supply electricity on terms which are reasonably necessary to
     meet that competition, save that the Licensee (taken together with its
     affiliates and related undertakings) shall not, in supplying or offering
     terms for the supply of electricity:

     (a)  show undue preference to any person (or class of persons) or exercise
          undue discrimination between any persons (or classes of person) within
          the relevant area or class of customers; or

     (b)  set terms in respect of any person (or class of persons) in a market
          in which the Licensee is dominant, save such persons who are within
          the relevant area or class of customers, which are unduly onerous.

                                       76
<PAGE>
 
5.   For the purposes of this Condition, terms are unduly onerous if the revenue
     from the supply of electricity to customers on those terms:

     (a)  significantly exceeds the costs of that supply; and

     (b)  exceeds such costs to a significantly greater degree than the revenue
          from supply to all other customers of the Licensee (and of its
          affiliates and related undertakings) within the same market exceeds
          the costs of supply to those customers.

6.   For the purposes of this Condition, a market may be defined by reference to
     a geographical area, or to a class of customer or both, save that no market
     defined by reference to Designated Customers shall comprise fewer than
     50,000 such customers.

7.   In determining, for the purposes of this Condition, whether any persons
     constitute a class of person, due regard shall be had to the circumstances
     of supply to such persons including (without limitation) volumes, load
     factors, conditions of interruptibility, location of premises being
     supplied and date and duration of the supply contract.

8.   For the purposes of this Condition, the Director shall determine any
     question as to:

     (a)  whether any area or class of customers constitutes a market for the
          supply of electricity;

     (b)  whether the Licensee is dominant in any market for the supply of
          electricity;

     (c)  whether there is established competition in respect of the supply of
          electricity in any area or to any class of customers; and

     (d)  whether any terms are predatory, having due regard to whether such
          terms:

          (i)   incorporate charges which do not reasonably cover the avoidable
                costs incurred in consequence of supplying the customers in
                question; and

          (ii)  are intended or are likely to restrict, distort or prevent
                competition in the supply of electricity.

                                       77
<PAGE>
 
9.   The Director may determine that the Licensee is dominant in a specified
     market:

     (a)  at any time prior to this Condition coming into force; or

     (b)  having first consulted with the Licensee and such other persons as he
          considers appropriate (and having taken into account any
          representations made to him), at any time after this Condition has
          come into force, and where the Director does make such a determination
          he shall immediately notify the Licensee.

10.  Where the Director has notified the Licensee of his determination in
     accordance with paragraph 9 that it is dominant in a specified market, the
     provisions of paragraphs 11 to 16 shall apply in respect of that market.

11.  Where this paragraph applies the Licensee shall, prior to supplying or
     offering to supply electricity under a tariff or Designated Supply Contract
     on any new terms, give to the Director at least 28 days' notice in writing
     of its intention to supply on such terms.

12.  For the purposes of this Condition, a tariff or Designated Supply Contract
     is on "new terms" if:

     (a)  it is a form of tariff or Designated Supply Contract under which the
          Licensee has not previously supplied or offered to supply electricity;

     (b)  it is a tariff or Designated Supply Contract in respect of which the
          Licensee is varying the terms as to price; or

     (c)  it is a tariff or Designated Supply Contract in respect of which the
          Licensee is varying any other terms in such a manner as to
          significantly affect the evaluation of that tariff or contract.

13.  Where the Licensee has given notice to the Director of its intention to
     supply on new terms it shall not supply or offer to supply electricity on
     such terms until either the period of notice given to the Director has
     expired and:

                                       78
<PAGE>
 
     (a)  the Director has not given or sent to the Licensee a counter-notice
          (the "counter-notice") in accordance with paragraph 14; or

     (b)  prior to the expiry of such period, the Director has informed the
          Licensee that he will not issue a counter-notice in respect of such
          terms.

14.  The Director may issue a counter-notice where, having considered the new
     terms and having had regard to the likely effects of issuing such counter-
     notice (including, but not limited to, the likely effect upon the business
     of the Licensee), he determines that further consideration is required to
     assess whether such terms are in breach of the provisions of this
     Condition.

15.  Where the Director issues a counter-notice in respect of any new terms the
     Licensee shall not supply or offer to supply electricity on such terms
     until either:

     (a)  a period of 3 months from the date of the counter-notice has expired;
          or

     (b)  prior to the expiry of such period, the Director indicates to the
          Licensee that he has no present intention of taking enforcement action
          under Section 25 of the Act in respect of such terms.

16.  Where the Director issues a counter-notice he may:

     (a)  give or send a copy of that counter-notice to any Interested Person;

     (b)  invite representations from Interested Persons as to the matters to
          which the counter-notice relates; and

                                       79
<PAGE>
 
     (c)  require the Licensee, within a reasonable period determined by the
          Director, to provide him with such further information relating to the
          new terms as he may specify (save that he may not by virtue of this
          paragraph require the Licensee to furnish him with information for the
          purpose of exercising his functions under Section 48 of the Act),

and the Director shall take into account any representations made to him by the
     Licensee in respect of such terms.

17.  The Director may, at any time after notifying the Licensee of his
     determination in accordance with paragraph 9 that it is dominant in a
     specified market, determine that the Licensee is no longer dominant in that
     market, and where he does make such a determination:

     (a)  the Director shall immediately notify the Licensee; and

     (b)  the provisions of paragraphs 11 to 16 shall cease to apply in respect
          of the specified market.

18.  For the purposes of this Condition, any reference to the Licensee being
     dominant in a market for the supply of electricity shall be treated as a
     reference to the Licensee, taken together with its affiliates and related
     undertakings, being so dominant.

19.  In this Condition:

     "Interested Persons"          means all Electricity Suppliers which supply
                                   electricity within the market or area or to
                                   the class of customers in question, the
                                   Relevant Consumers' Committee and such other
                                   persons or bodies as in the opinion of the
                                   Director have a legitimate interest in the
                                   terms on which the Licensee supplies
                                   electricity.

     "terms"                       means all the terms on which a supply of
                                   electricity is offered or provided which
                                   significantly affect the evaluation of that
                                   supply, and shall include all terms as to
                                   price.

CONDITION 4B:  DURATION OF DISCRIMINATION CONDITIONS
- ----------------------------------------------------


1.   Condition 4A shall cease to have effect (in whole or in part, as the case
     may be) if the Licensee makes a disapplication request in accordance with
     this Condition and:

     (a)  the Director agrees in writing to that request; or

     (b)  the application of Condition 4A (in whole or in part) is terminated by
          notice given by the Licensee in accordance with paragraph 4 or 5 of
          this Condition.

2.   A disapplication request pursuant to this Condition may be made by the
     Licensee only where the Director has notified it, in accordance with
     paragraph 9 of Condition 4A, of his determination that the Licensee is
     dominant in a specified market, and any such request shall:

     (a)  be made in writing to the Director;

     (b)  specify whether the request relates to the whole of Condition 4A or
          any part or parts thereof; and

     (c)  state the date (the "disapplication date") from which the Licensee
          wishes the specified provisions of Condition 4A to cease to have
          effect, which date shall be in accordance with paragraph 3 and not
          earlier than 12 months after the date on which the request is made.

3.   Where the Licensee was notified by the Director prior to this Condition
     coming into force of his determination that the Licensee is dominant in a
     specified market, no disapplication request made by the Licensee shall be
     effective to disapply any of the provisions of Condition 4A prior to 31
     March 2000.

                                       81
<PAGE>
 
4.   If the Director has not by the date which is 6 months prior to the
     disapplication date made a reference to the Monopolies Commission (under
     Section 12 of the Act) relating to the modification of Condition 4A, the
     Licensee may give to the Director a notice in writing terminating the
     application of such of the provisions of Condition 4A as are specified in
     the disapplication request with effect from the disapplication date or from
     any later date specified in the notice.

5.   If the Monopolies Commission reports on a reference made by the Director
     relating to the modification of Condition 4A and does not conclude that the
     disapplication of any of the provisions of that Condition (being provisions
     specified in the disapplication request) would or may be expected to
     operate against the public interest, the Licensee may within 30 days of the
     publication of the report under Section 13 of the Act give to the Director
     notice in writing terminating the application of such provisions with
     effect from the disapplication date or any later date specified in the
     notice.

     (b)  qualifying non-fossil generation; and

     (c)  generation from any source other than as referred to in sub-paragraphs
          (a) and (b) above.

2.   In respect of each category referred to in paragraph 1 above, and subject
     to paragraph 4 below, the Licensee shall:

     (a)  itself purchase;

     (b)  procure any affiliate of the Licensee to purchase; and

     (c)  insofar as it is able through the exercise of voting rights or
          otherwise to do so, procure any related undertaking of the Licensee or
          any defined undertaking to purchase

     electricity at the best effective price reasonably obtainable having regard
     to the sources available.

3.   In determining the effective price at which electricity is purchased by the
     Licensee or any affiliate or related undertaking of the Licensee or any
     defined undertaking, regard shall be had to any payments made or received
     or to be made or received for the grant of or pursuant to any electricity
     purchase contract.

4.   In the discharge of it obligations under paragraph 2 above, the Licensee
     may additionally have regard to any considerations liable to affect its
     ability and that of any affiliate of the Licensee to discharge its
     obligations under this Condition in the future, including the future
     security, reliability and diversity of sources of electricity available for
     purchase.

                                       83
<PAGE>
 
5.   In this Condition (and subject to paragraph 6) references to qualifying
     renewable generation and to qualifying non-fossil generation shall refer to
     generation from capacity of that description which:

     (a)  has been contracted by the Licensee or any defined undertaking under
          an arrangement certified by the Secretary of State under Section 32
          (7) of the Act which was entered into prior to the date this Licence
          enters force; or

     (b)  is available to be contracted under arrangements to be produced to the
          Director in satisfaction of an obligation imposed on the Licensee by
          Order made under Section 32 of the Act after this Licence enters
          force.

6.   Notwithstanding that generation may previously have been contracted as
     being qualifying renewable generation or qualifying non-fossil generation
     (as the case may be), it shall cease to be so treated to the extent that:

     (a)  the Licensee (or any affiliate or related undertaking of the Licensee
          or any defined undertaking) enjoys contractual freedom to vary or
          discontinue its obligation to purchase such generation; and

     (b)  capacity from which qualifying renewable or non-fossil generation (as
          the case may be) is otherwise contracted by the Licensee or any
          affiliate or related undertaking of the Licensee or any defined
          undertaking is equal to or exceeds the aggregate capacity specified in
          any Orders previously made under Section 32 of the Act and continuing
          in force, as being required to be available to the Licensee at that
          time or in respect of any future period covered by such Orders.

7.   Paragraphs 2, 3 and 4 of this Condition shall apply mutatis mutandis where
                                                         ----------------  
     the Licensee exercises a discretion or (by agreement or otherwise) varies
     the terms of an existing contract (whether or not entered into prior to the
     date of entry into force of this Licence) in such a manner as to alter the
     effective price under such contract.

8.   In this Condition:

     "defined undertaking"    means Non-Fossil Purchasing Agency Limited or
                              other entity through which the Licensee enters

                              Section 33 of the Act.

     "purchase"               includes the acquisition of electricity from
                              sources falling to be treated as own-generation
                              for the purpose of Condition 6, and the purchase
                              of electricity under electricity purchases

     "qualifying non-fossil   shall include generation from renewable sources
     generation"              which for the time being has not been contracted
                              as being qualifying renewable generation.

CONDITION 6:   RESTRICTION ON OWN-GENERATION CAPACITY
- -----------------------------------------------------


1.   The Licensee shall procure that, with effect from the transfer date, the
     Generation Business of the Licensee is held as a Separate Business by or
     through a wholly-owned subsidiary of the Licensee.

2.   Save with the prior written consent of the Director or in the circumstances
     described in paragraph 3 below, the Licensee shall at all times ensure that
     the sum of the amount in megawatts (calculated as provided under paragraphs
     4 and 5 below) represented by the declared net capacity of the Licensee's
     own-generation sets and the appropriate share of the declared net capacity
     of generation sets in which the Licensee has an accountable interest shall
     not exceed 800 megawatts.

3.   Where the Licensee is in breach of paragraph 2 by reason of the acquisition
     of own- generation sets or an accountable interest in other generation sets
     in consequence of the occurrence of a specified event affecting the
     operator or any third party, the Licensee shall forthwith notify the
     Director for the purpose of obtaining such consent as is specified in
     paragraph 2.

4.   For the purposes of calculating the limit under paragraph 2 and subject to
     paragraph 5, there shall be attributed to the Licensee:

     (a)  the whole of the declared net capacity represented by own-generation
          sets; and

     (b)  the appropriate share (namely the share representing the Licensee's
          economic interest therein) of the declared net capacity of generation
          sets in which it has an accountable interest, ascertained in such
          manner as the Licensee with the approval of the Director may
          determine.

5.   Where the Director is satisfied that by virtue of the Licensee's economic
     interest (ascertained in such manner as the Director may determine)
     therein:

     (a)  generation sets in which the Licensee has only an accountable interest
          should more properly be treated as own-generation sets; or

                                       86
<PAGE>
 
     (b)  own-generation sets should more properly be treated as sets in which
          the Licensee only has an accountable interest; or

     (c)  own-generation sets, or generation sets in which the Licensee has an
          accountable interest, should not be treated as falling in either
          category; or

     (d)  generation sets not declared as sets in which the Licensee has an
          accountable interest, should be treated as generation sets in which
          the Licensee has an accountable interest;

     the Director may issue directions to that effect.

6.   For the purposes of this Condition and subject to paragraphs 5 and 9, the
     Licensee shall have an accountable interest in a generation set in
     circumstances where (such generation set not being an own-generation set of
     the Licensee):

     (a)  the operator is a related undertaking of the Licensee or any affiliate
          of the Licensee; or

     (b)  the Licensee or any affiliate of the Licensee is in partnership with
          or is party to any arrangement for sharing profits or cost-savings or
          any joint venture with the operator or with any third party with
          regard to the operator; or

     (c)  the Licensee or any affiliate of the Licensee has (directly or
          indirectly):

          (i)    any beneficial shareholding interest in the operator; or

          (ii)   any beneficial underlying interest in the generation set; or

          (iii)  provided or agreed to provide finance to the operator otherwise
                 than on arm's length terms; or

          (iv)   provided or agreed to provide, or has determined or is
                 responsible for determining the price (or other terms affecting
                 the financial value) of, the fuel used in the generation sets;

                                       87

                 and is entitled under a contract of not less than 5 years'
                 duration:

                 (aa)  to a share of the declared net capacity of the generation
                       set; or

                 (bb)  to a share of the declared net capacity of a generation
                       set being the own-generation set of another Authorised
                       Electricity Operator or in which such Authorised
                       Electricity Operator has an accountable interest, under
                       arrangements for the exchange of capacity entitlement or
                       supplies of electricity representing such entitlement
                       between the licensee or its affiliate and such Authorised
                       Electricity Operator.

7.   Paragraph 6 shall be applied in relation to the calculation of an
     accountable interest in generation sets of any other Authorised Electricity
     Operator as if the references therein to the Licensee were replaced by
     references to such Authorised Electricity Operator.

8.   References in paragraph 6 to contracts giving entitlements to a share of
     declared net capacity shall include electricity sale or purchase contracts
     where rights under such contract are exercisable by reference to an
     identified generation set or to amounts generated at such set.

9.   The Licensee shall not be deemed to have an accountable interest in a
     generation set where:

     (a)  such generation set is owned and operated by the National Grid Company
          plc or a wholly-owned subsidiary thereof under a Licence granted
          pursuant to Section 6 of the Act; or

     (b)  the Licensee's interest arises wholly under the terms of the Pooling
          and Settlement Agreement or (other than as provided in paragraph 8)
          under any electricity purchase or sale contract; or

     (c)  the Licensee's interest arises solely by virtue of arrangements for
          the sharing with the operator of any generation set of the risks
          associated with changes in the price of fuel used by the generation
          set during the term of any such contract as is referred to in
          paragraph 6 or 8 above.

                                       88
<PAGE>
 
10.  The Licensee shall, on each such occasion as it provides to the Director
     separate accounts for the Generation Business pursuant to paragraph 3(b)
     (i) of Condition 2 and at any other time upon request of the Director,
     provide to the Director a statement:

     (a)  confirming compliance with paragraphs 1, 2 and 3 above as at the date
          of the statement and throughout the period since the last such
          statement; and

     (b)  identifying (in such detail and with such supporting documents or
          information as the Director may require) the amount of capacity in
          megawatts represented by the declared net capacity of own-generation
          sets attributable to the licensee and the appropriate share of the
          Licensee in the declared net capacity of generation sets in which the
          Licensee has an accountable interest, as at the date of the statement.

11.  Where the Director is satisfied that the basis of calculation used by the
     Licensee is not in conformity with paragraphs 4 and 5 above, the Director
     may issue directions specifying an alternative basis of calculation, and
     the basis of calculation by the Licensee shall be adjusted accordingly with
     effect from the date of issue of the directions or such other date as may
     be specified in the directions.

                                which the Licensee or an affiliate of the
                                Licensee is the operator and references to own-
                                generation sets of another Authorised
                                Electricity Operator shall be construed as if
                                the reference herein to the Licensee were
                                replaced by reference to that Authorised

1.   The Licensee shall ensure that any tariffs fixed under Section 18 of the
     Act shall be so framed as separately to identify:

     (a)  the use of system element in the Licensee's charges; and

     (b)  the charges in respect of the supply of electricity to tariff
          customers.

2.   Where the Director considers that by reason of the complexity of any such
     tariffs fixed by the Licensee, simplified explanatory statements are
     required or expedient for the understanding of tariff customers, the
     Director may direct the Licensee to draw up such explanatory statements and
     thereafter to publish them with the tariffs to which they relate.

          Licence granted to another Electricity Supplier to supply electricity
          (in this Condition known as the "First Supplier"); and

     (b)  considers that the Licensee is able to supply electricity to the
          customers of the First Supplier without significantly prejudicing the
          supplies of electricity which the Licensee makes or is contracted to
          make.


2.   The Director shall only issue a direction in accordance with paragraph 1
     when the Secretary of State or, as the case may be, the Director has served
     the First Supplier with a notice that he is revoking the First Supplier's
     Licence to supply electricity in accordance with the terms of the First
     Supplier's Licence, or such earlier date as the Director may agree with the
     First Supplier.

3.   A direction issued in accordance with paragraph 1 shall require that the
     Licensee shall, within the period specified by the Director, send a written
     notice in a form approved by the Director to each of the persons or
     premises specified or described in the direction:

     (a)  informing the customer in question that, notwithstanding any contract
          he may have with the First Supplier, the First Supplier is no longer
          supplying him with electricity and has not done so since the
          revocation took effect or, where the notice has been sent before the
          revocation has taken effect, will be no longer supplying him with
          electricity when it takes effect;

     (b)  informing the customer that the customer must from the moment the
          revocation takes effect enter into a new contract for supply with
          another Electricity Supplier of the customer's choice, and that he is
          free to request a supply from the Licensee; and

     (c)  setting out the terms upon which the Licensee is prepared to supply
          electricity if requested.

     relating to the effective implementation of trading and other arrangements
     between the Licensee and other Relevant Parties which, in the reasonable

     electricity.

3.   The Programme Implementation Agreement may include provisions relating to:

     (a)  the operation and management of procedures for the testing, trialing

     (b)  the obligations of each of the Relevant Parties in respect of the
          procedures defined under sub-paragraph (a);

          persons specified in the Agreement;

     (e)  the determination of the specification of systems, processes and
          procedures to be tested, trialed and integrated in accordance with the
          Agreement, except in those circumstances where the Director considers
          that any of the Relevant Parties has entered into another agreement
          which adequately provides for such specification to be otherwise
          determined;

          ii)  advise the Director and the Relevant Parties of any matters upon
               which they may reasonably seek advice in relation to matters

               of procedures established under the Agreement; and

          iii) undertake such other functions as in the reasonable opinion of
               the Director are necessary to provide for the effective and
               timely facilitation of competition in electricity supply.


4.   The Programme Implementation Agreement shall be that established by
     agreement between the Relevant Parties with the approval of the Director
     or, where the Relevant Parties cannot agree (or where in the opinion of the
     Director such agreement is unlikely to be reached within a reasonable
     period) and where:


     (a)  the Director has sent to each of the Relevant Parties a notice (the
          "proposals notice") setting out his own proposals in relation to the
          content of the Programme Implementation Agreement; and

     (b)  following consideration of any comments received from any of the
          Relevant Parties within 21 days of the issue of the proposals notice,
          and having made such changes to his proposals as the Director
          considers appropriate, the Director has given to each of the Relevant
          Parties a notice setting out his final proposals (the "confirmation
          notice"),

                                       96

     issue of the confirmation notice the parties have reached agreement with
     the approval of the Director as to an alternative, be established in
     accordance with the terms of the Director's confirmation notice.

5.   With regard to the provisions of paragraphs 1 to 4, and following
     consultation with the Relevant Parties and with such other persons or
     bodies as appear to the Director to represent the interests of those likely
     to be affected, the Director may issue a direction that specified parts of
     the Relevant Conditions shall take effect at such time and in such cases or
     circumstances as he shall direct.

6.   In issuing a direction in accordance with paragraph 5 the Director shall
     have regard to the need to provide for effective arrangements to facilitate
     competition in the supply of electricity to customers and for the effective
     maintenance of existing trading arrangements in respect of the supply of
     electricity.

7.   This Condition shall cease to be in force on whichever is the latest of the
     following dates:

     (a)  30 September 1998;

          Licensee or any third party; and

     (b)  omit information the disclosure of which would place the Licensee in
          breach of Condition 12.

     its use of system charges in respect of any agreement for use of system
     save to the extent that it has given prior notice of the amendment in

          additional entry or exit points on such system or otherwise;

     (b)  the ability or likely future ability of the Licensee to recoup a

7.   The Licensee shall not be obliged pursuant to this Condition to offer to

CONDITION 8C:   REQUIREMENT TO OFFER STANDARD TERMS OF CONNECTION
- -----------------------------------------------------------------


1.   The Licensee shall, within 28 days after this Condition has come into
     force, prepare and submit to the Director for his approval the standard
     terms of an agreement (the "Standard Terms of Connection") to provide, as
     between the Licensee and any customer, for the retention of an established
     connection at premises which are to be supplied with electricity through
     such a connection.

2.   The Licensee may, subject to the approval of the Director, prepare
     different Standard Terms of Connection for different cases or classes of
     customer or premises, clearly identifying the criteria used to distinguish
     between such cases or classes.

3.   The Licensee shall from time or time, and whenever requested to do so by
     the Director, review the Standard Terms of Connection with a view to
     determining whether any revision should be made to such terms, and in the
     course of the review the Licensee shall consult with the Relevant
     Consumers' Committee, all other public electricity suppliers and all Second
     Tier Suppliers which supply electricity within the authorised area.

4.   At the conclusion of any review in accordance with paragraph 3 the Licensee
     shall submit to the Director:

     (a)  a proposal for the revision of the Standard Terms of Connection (or,
          where the Licensee considers it appropriate in all the circumstances,
          a proposal that no revision should be made to the Standard Terms of
          Connection); and

     (b)  the reasons for its proposal, together with a summary of responses
          received from such parties as were consulted by the Licensee.

5.   A proposal made by the Licensee in accordance with paragraph 4 shall
     require to be approved by the Director and, following such approval in
     writing, the Licensee shall accordingly revise (or, as the case may be,
     shall make no revision to) the Standard Terms of Connection.

                                      114

6.   The Licensee shall, in such manner as will in the opinion of the Licensee
     secure adequate publicity therefor:

     (a)  publish, no later than 31 December 1997, the Standard Terms of
          Connection approved by the Director in accordance with paragraph 1;
          and

     (b)  publish, within 21 days after receiving the approval of the Director,
          any revision to the Standard Terms of Connection in accordance with
          paragraph 5.

7.   The Licensee shall not:

     (a)  subject to paragraph 8, enter into a contract with a customer for the
          supply of electricity to premises which are to be supplied through an
          established connection without at the same time (in respect of such
          premises) entering into an agreement with the customer on the Standard
          Terms of Connection; or

     (b)  do anything to prevent the conclusion of an agreement on the Standard
          Terms of Connection between itself and a customer of any Authorised
          Electricity Operator which is acting as agent for the Licensee in
          accordance with an agreement for use of system.

8.   The Licensee may at any time agree with any person (by way of variation to
     the Standard Terms of Connection) terms for the retention of a particular
     established connection which differ from the Standard Terms of Connection
     where such different terms are appropriate in all the circumstances.

CONDITION 8D:   FUNCTIONS OF THE DIRECTOR
- -----------------------------------------


1.   If, after a period which appears to the Director to be reasonable for the
     purpose, the Licensee has failed to enter into an agreement with any person
     entitled or claiming to be entitled thereto pursuant to a request under
     Condition 8B or 8C, the Director may, on the application of such person or
     the Licensee, settle any terms of the agreement in dispute between the
     Licensee and that person in such manner as appears to the Director to be
     reasonable having (in so far as relevant) regard in particular to the
     following considerations:

     (a)  that such person should pay to the Licensee:

           i)  in the case of the provision of top-up or standby supplies or
               sales of electricity, such sum as is determined in accordance
               with paragraph 6 of Condition 8;

          ii)  in the case of exempt supply services, such sum as is determined
               in accordance with paragraph 7 of Condition 8;

          iii) in the case of provision of use of system, the use of system
               charges determined in accordance with paragraph 8 of Condition 8;
               and

          iv)  in the case of provision of a connection or a modification to an
               existing connection to the system, the whole or an appropriate
               proportion (as determined in accordance with paragraph 5 of
               Condition 8B) of the costs referred to in sub-paragraph 9(a) of
               Condition 8, together with a reasonable rate of return on the
               capital represented by such costs;

     (b)  that the performance by the Licensee of its obligations under the
          agreement should not cause it to be in breach of those provisions
          referred to at sub-paragraph 7(a) of Condition 8B;

     (c)  that any methods by which the Licensee's Distribution System is
          connected to any other system for the transmission or distribution of
          electricity accord (in so far as applicable to the Licensee) with the
          Distribution Code and with the Grid Code;
 

                                      116
<PAGE>
 
         (d)      that the terms and conditions of the agreement so settled by
                  the Director and of any other agreements entered into by the
                  Licensee pursuant to an application under Condition 8B or 8C
                  should be, so far as circumstances allow, in as similar a form
                  as is practicable; and

         (e)      in the case of exempt supply services, that the agreement for
                  the provision of exempt supply services should make provision
                  for all the matters set out at paragraph 5 of Condition 8B.

2.       In so far as any person entitled or claiming to be entitled to an offer
         under Condition 8B or 8C wishes to proceed on the basis of the
         agreement as settled by the Director, the Licensee shall forthwith
         enter into and implement such agreement in accordance with its terms.

3.       If either party to such agreement proposes to vary the contractual
         terms of any agreement for exempt supply services, for the provision of
         a connection or for the modification of an existing connection to the
         Licensee's Distribution System, for the retention of an established
         connection to such Distribution System or for use of system entered
         into pursuant to Condition 8B or 8C or under this Condition in any
         manner provided for under such agreement, the Director may, at the
         request of that party, settle any dispute relating to such variation in
         such manner as appears to the Director to be reasonable.

                         supply of electricity are rendered to the customer, on
                         a quarterly basis (it being sufficient that the
                         information is included on or with any bill or
                         statement); or

         (b)      there has been interference with the meter to alter its
                  register or prevent it from duly registering the quantity of
                  electricity supplied.

3.       Where a person other than the Licensee is the supplier of electricity
         to premises within the authorised area the Licensee shall, as soon as

1.       On application made by any person the Licensee shall, subject to
         paragraph 5, offer to enter into an agreement authorising that person
         to connect metering equipment to the Licensee's Distribution System.

2.       In making an offer to enter into an agreement specified in paragraph 1,
         the Licensee shall set out:

         (a)      the date from which the applicant is authorised to undertake
                  connections;

         (b)      the procedures to be adopted by the applicant when making
                  connections, with particular regard to those relating to
                  safety; and

         (c)      such other detailed terms as are or may be appropriate for the
                  purposes of the agreement.

3.       The Licensee shall offer terms for agreements in accordance with
         paragraph 1 as soon as practicable and (save where the Director
         consents to a longer period) in any event not more than 28 days after
         receipt by the Licensee from any person of an application containing
         all such information as the Licensee may reasonably require for the
         purpose of formulating the terms of the offer

4.       In the offering of the terms in accordance with paragraph 1, the
         Licensee shall not show undue preference to or exercise undue
         discrimination against any person or class of persons.

         to enter or to enter into any agreement:

         (a)      (in respect of non-half hourly metering equipment) which comes
                  into effect prior to 1 April 2000; or

         (b)      where to do so would be likely to cause the Licensee to be in
                  breach of those provisions referred to at sub-paragraph 7(a)
                  of Condition 8B.

6.       If, after a period which appears to the Director to be reasonable for
         the purpose, the Licensee has failed to enter into an agreement with
         any person entitled or claiming to be entitled thereto pursuant to a
         request under this Condition, the Director may, on the application of
         such person or the Licensee, settle any terms of the agreement in
         dispute between the Licensee and that person in such manner as appears
         to the Director to be reasonable.

7.       In so far as any person entitled or claiming to be entitled to an offer
         under this Condition wishes to proceed on the basis of the agreement as
         settled by the Director, the Licensee shall forthwith enter into and
         implement such agreement in accordance with its terms.

8.       If the Licensee or other party to such agreement proposes to vary the
         terms of any agreement entered into pursuant to this Condition in any
         manner provided for under such agreement, the Director may, at the
         request of the Licensee or other party to such agreement, settle any
         dispute relating to such variation in such manner as appears to the
         Director to be reasonable.

         intended or is likely to restrict, distort or prevent competition in
         the supply of electricity.

         Licensee's complying with the provisions of paragraph 3 below or by the
         making by the Licensee of such other arrangements as may have been
         previously approved in writing for the purpose by the Director.

3.       The Licensee may discharge the duty imposed by paragraph 1 by:

         (a)      for so long as the relevant condition is met, purchasing as a
                  pool member under the terms of the Pooling and Settlement
                  Agreement quantities of electricity which are at all times
                  sufficient to meet the demands of all qualifying customers of
                  the Licensee; and

         (b)      for so long as the relevant condition is met, and save by

                  Distribution System or in circumstances of force majeure
                  affecting either the Licensee's Distribution System or the
                  quantities of electricity delivered into that system, not:

                  (i)      making voltage reductions outside statutory limits;
                           or

                  (ii)     interrupting or reducing supplies to any qualifying

4.       The relevant condition referred to in paragraph 3 is that there should
         at any relevant time be electricity available to be purchased under the
         terms of the Pooling and Settlement Agreement at a price less than the
         ceiling price.

5.       The Licensee shall upon request by the Director provide to the Director
         such information as the Director may require for the purpose of
         monitoring compliance with this Condition and to enable the Director
         (having regard to his statutory duties) to review the operation of the
         generation security standard.

6.       The provisions of this Condition are without prejudice to the duties of

7.       In this Condition:

         "ceiling price"            means such price as would be equal to the
                                    Pool Selling Price in circumstances where
                                    the corresponding Pool Purchase Price was an
                                    amount equal to the Value of Lost Load.

         "generation security       means such standard of generation security 
          standard"                 as will ensure that:

                                    (a)     the supply of electricity to
                                            qualifying customers will not be
                                            discontinued in more than 9 years in
                                            any 100 years; and

                                            usual operational limits in more
                                            than 30 years in any 100 years by
                                            reason of insufficiency of
                                            electricity generation available for
                                            the purposes of supply by the
                                            Licensee to its qualifying customers
                                            at times of annual system peak
                                            demand.

     become liable for the provision of such services and of the other terms,
     likely to have a material impact on the conduct of his business, upon which
     the service would be provided and (without prejudice to the foregoing)

2.   The statements referred to in paragraph 1 shall include:

     (a)  a schedule of charges for such services; and

1.   If, after a period which appears to the Director to be reasonable for the
     purpose, the Licensee has failed to enter into an agreement with any person
     entitled or claiming to be entitled thereto pursuant to a request under
     Condition 11C, the Director may, on the application of such person or the
     Licensee, settle any terms of the agreement in dispute between the Licensee
     and that person in such manner as appears to the Director to be reasonable
     having (in so far as relevant) regard in particular to the following
     considerations:

     (a)  that such person should pay in respect of the services required the
          whole or the appropriate proportion of such sum as is determined in
          accordance with paragraph 4 of Condition 11E;

     (b)  that the performance by the Licensee of its obligations under the
          agreement should not cause it to be in breach of those provisions
          referred to at sub-paragraph 7(a) of Condition 8B; and

     (c)  that the terms and conditions of the agreement so settled by the
          Director and of any other agreements entered into pursuant to a
          request under Condition 11C should be, so far as circumstances allow,
          in as similar a form as is practicable.

2.   In so far as any person entitled or claiming to be entitled to an offer
     under Condition 11C wishes to proceed on the basis of the agreement as
     settled by the Director, the Licensee shall forthwith enter into and
     implement such agreement in accordance with its terms.

3.   If any party to such agreement proposes to vary the contractual terms of
     any agreement for any Metering and Data Services entered into pursuant to
     Condition 11C or this Condition in any manner provided for under such
     agreement, the Director may, at the request of that party, settle any
     dispute relating to such variation in such manner as appears to the
     Director to be reasonable.

4.   The Director may (following consultation with the Licensee) issue
     directions relieving the Licensee of its obligations under Condition 11C in
     respect of such parts of that Condition and to such extent as may be
     specified in the directions.

one month of the Director giving notice to the Licensee of its amount if that
notice is given within 6 months of the beginning of the year in respect of which
the fee is payable.

Condition 30:  Designated Premises
- ----------------------------------

1.   For the purposes of this Licence, the question whether any premises are
     "Designated Premises" shall be determined in accordance with the provisions
     of this Condition.

2.   Premises are Designated Premises if they are either:

     (a)  Domestic Premises; or

     (b)  premises at which, in the reasonable expectation of the Licensee at
          the time of entering into a contract for the supply of electricity to
          such premises, the normal annual consumption of electricity will
          amount to no more than 12,000 kWh,

     but excluding premises referred to at sub-paragraph (b) which receive an
     unmetered supply, or which are supplied through half-hourly or maximum
     demand metering equipment or under the terms of a multi-site contract.

3.   For the purposes of this Condition, a "multi-site contract" is a contract
     for the supply of electricity both to any premises which do not fall within
     the terms of sub-paragraphs 2(a) or (b) and to one or more other premises
     (not being Domestic Premises), all of which premises are owned or occupied
     by:

     (a)  the same person or body of persons whether corporate or unincorporate;
          or

     (b)  an undertaking (the "principal undertaking") and any holding company,
          subsidiary, or subsidiary of the holding company of that principal
          undertaking, or any other undertaking in which the principal
          undertaking has a participating interest.

4.   Any premises supplied by the Licensee which (in accordance with paragraphs
     1 to 3) were not Designated Premises at the time at which the Licensee
     entered into a contract for their supply shall, notwithstanding subsequent
     changes to the nature or level of the consumption of electricity at those
     premises, not become Designated Premises for the purposes of this Licence
     prior to the time at which they cease to be supplied by the Licensee.

                                      183
<PAGE>
 
5.   Any premises supplied by the Licensee which (in accordance with paragraphs
     1 to 3) were Designated Premises at the time at which the Licensee entered
     into a contract for their supply shall cease to be Designated Premises for
     the purposes of this Licence where:

     (a)  they have been continuously supplied by the Licensee for a period of
          at least 12 months and:

          (i)  they are not, or are no longer, Domestic Premises; and

          (ii) it is reasonably to be expected that the normal annual
               consumption of electricity at the premises will amount to more
               than 12,000 kWh; or

     (b)  (not being, or being no longer, Domestic Premises) the premises
          commence receipt of an unmetered supply or a supply through half-
          hourly or maximum demand metering equipment or under the terms of a
          multi-site contract.

6.   In this Condition:

     "maximum demand metering           means metering equipment which is       
     equipment"                         capable of recording the demand for     
                                        electricity supplied to premises during 
                                        the half hour of maximum demand in any  
                                        period of supply.

CONDITION 33:  REVISION OF THE CONTRACT TERMS CONDITIONS
- --------------------------------------------------------

1.   The Director, in accordance with the provisions of this Condition, may from
     time to time review (in whole or in part) the provisions and operation of
     the Contract Terms Conditions in the licences of all Electricity Suppliers
     with a view to establishing whether any revision should be made to the
     Contract Terms Conditions in all such licences.

2.   At the commencement of any review by the Director, the Director shall:

     (a)  give to all Relevant Parties a notice in writing which sets out the
          terms of the review and of any proposals in connection therewith and
          which invites the submission of any representations by a specified
          date (being not less than 28 days after the date of the notice); and

     (b)  publish such notice or an accurate summary of it in a manner which
          will, in the opinion of the Director, secure adequate publicity for
          it.

3.   On receiving from the Director notice of such a review the Licensee may
     submit any representations on matters within the terms of the review by the
     date specified in the notice.

4.   As soon as practicable following the completion of any such review, the
     Director shall send to each Relevant Party, and to any person who has made
     representations to him by virtue of the notice published under sub-
     paragraph 2(b), a copy of:

     (a)  a report on the outcome of such review;

     (b)  any revisions which he proposes to make, having regard to any
          representations received during such review, to the Contract Terms
          Conditions in the licences of all Electricity Suppliers;

     (c)  a statement of his reasons for proposing those revisions; and

                                      187
<PAGE>
 
     (d)  a notice specifying the time (being not less than 28 days from the
          date the Director issues the notice) within which Electricity
          Suppliers which are entitled to supply electricity to Designated
          Premises shall state whether or not they consent to the proposed
          revisions to the Contract Terms Conditions in their licences.

5.   A revision proposed to be made by the Director to the Contract Terms
     Conditions of all Electricity Suppliers may be made only where the Director
     is satisfied that the figures determined in accordance with paragraphs 6
     and 7 (expressed as a percentage) are each not less than 90 per cent.

6.   The figure determined in accordance with this paragraph shall be calculated
     under the following formula:

                                 C  x 100
                                --- 
                                C+N

     where:

          C =  the number of Designated Premises supplied on contract by
               consenting Electricity Suppliers; and

          N =  the number of Designated Premises supplied on contract by
               non-consenting Electricity Suppliers

     as estimated (in each case) by the Director on the basis of the information
     most recently available to him.

7.   The figure determined in accordance with this paragraph shall be calculated
     under the following formula:

                                 C  x 100
                                --- 
                                C+N

     where:

          C =  the number of consenting Electricity Suppliers; and

          N =  the number of non-consenting Electricity Suppliers.

                                      188
<PAGE>
 
8.   In paragraphs 6 and 7 the expressions "consenting" and "non-consenting"
     refer (as the case may be) to the consent or otherwise of Electricity
     Suppliers which are entitled to supply electricity to Designated Premises
     to the proposed revision to the Contract Terms Conditions in their
     licences.

9.   Where the Director is satisfied that the figures determined in accordance
     with paragraphs 6 and 7 (expressed as a percentage) are each not less than
     90 per cent the Director may amend the Contract Terms Conditions of the
     Licensee in accordance with the proposed revision.

10.  No revision made to the Contract Terms Conditions by virtue of this
     Condition may introduce an obligation in respect of any matter other than
     one which:

     (a)  is provided for, or is reasonably ancillary to a matter provided for,
          under the Contract Terms Conditions on the date on which such
          Conditions come into force;

     (b)  concerns the terms of contracts offered or entered into by the
          Licensee for the supply of electricity to Designated Premises; or

     (c)  concerns any dealings with customers by or on behalf of the Licensee
          prior to and for the purpose of offering or entering into contracts
          for the supply of electricity to Designated Premises.

11.  In this Condition:

     "Relevant Parties"                 means the Licensee, all other
                                        Electricity Suppliers, the Electricity
                                        Consumers' Committees and such other
                                        persons or bodies as in the opinion of
                                        the Director are representative of those
                                        likely to be affected by a revision to
                                        the Contract Terms Conditions.

CONDITION 34:     DESIGNATED SUPPLY CONTRACTS
- ---------------------------------------------

1.   A Designated Supply Contract is a contract for the supply of electricity to
     Designated Premises, as varied from time to time, which complies with the
     provisions of this Condition.

2.   Without prejudice to its rights and obligations under the Act, the Licensee
     shall not supply electricity to Designated Premises on contract except
     under a Designated Supply Contract.

     different areas, cases and circumstances;
     
     (b)  set out all the terms and conditions, including terms as to price, on
     which the Licensee will supply electricity in the relevant case; and

     (c)  contain terms reflecting the termination provisions of Conditions 38
     and 39.

4.   Any Designated Supply Contract for both the supply of electricity and the
     provision of goods or services shall identify separately the charge for
     that supply from the charge for the goods or services.

5.   Where a Designated Supply Contract may be terminated by a customer by
     virtue of any provision included in that contract in compliance with
     Conditions 38 and 39, the Licensee may at its discretion accept a lesser
     period of notice than is specified in that provision.

6.   Nothing in this Licence shall prevent the Licensee from entering into a
     Designated Supply Contract which contains provisions for its termination

CONDITION 35:  CONTRACTUAL TERMS
- --------------------------------


1.   Where the Licensee offers to supply electricity to Domestic Premises under
     Designated Supply Contracts, it shall have available forms of Designated
     Supply Contract which provide for the payment of charges for electricity
     supplied to Domestic Premises:

     (a)  by prepayment through a prepayment meter;

     (b)  by different methods, including:

          (i)   by cash, at such places and to such persons as are reasonable in
                all the circumstances; and

          (ii)  by cheque, and

     (c)  at a reasonable range of different intervals, including:

          (i)   paying monthly a predetermined sum; and

          (ii)  paying quarterly in arrears.

2.   Before entering into any contract to supply electricity to Domestic
     Premises (other than through a prepayment meter) the Licensee shall inform
     the customer of and offer to enter into Designated Supply Contracts which
     comply with sub-paragraphs 1(b) and (c).

3.   The Licensee shall process all requests for a supply of electricity to
     Designated Premises without undue preference or undue discrimination.

4.   The Licensee shall send copies of each of the forms of Designated Supply
     Contract (as revised from time to time) under which it supplies or offers
     to supply electricity:

     (a)  on receipt of a request, to any person; and

     (b)  not later than the date on which it first offers to supply electricity
          under each such form of Designated Supply Contract (or revision
          thereof), to the Director.

                                      191
<PAGE>
 
5.   The Licensee shall prepare, in respect of each form of Designated Supply
     Contract:

     (a)  a document which sets out an accurate summary of the Principal Terms
          of that form of Designated Supply Contract; and

     (b)  particulars of inducements offered to any person entering into such a
          contract which might reasonably be expected materially to influence
          the decision whether or not to enter into it.

6.   The Licensee shall publish the documents and particulars referred to at
     paragraph 5 in a manner that will in the opinion of the Licensee secure
     adequate publicity for them, and shall send copies of them to the Director
     no later than the date on which they are published.

CONDITION 36:  NOTIFICATION OF TERMS
- ------------------------------------


1.   Before entering into any Designated Supply Contract the Licensee shall take
     all reasonable steps to draw the attention of the customer to the Principal
     Terms of the contract.

2.   Where the Licensee has entered into a Designated Supply Contract it shall
     (except where it has already done so) provide the customer within 2 working
     days of the date of the contract with a copy of its full terms and
     conditions.

3.   Subject to paragraph 4 the Licensee shall, at least 30 days before any
     Designated Supply Contract to supply electricity for a specified period is
     due to expire, send to the customer:

     (a)  a written offer to enter into a new contract for supply from the date
          of expiry of the existing contract, drawing the attention of the
          customer to the Principal Terms relevant to that offer;

     (b)  an accurate summary of the Principal Terms of other contracts which
          the Licensee will make available to the customer; and

     (c)  details of how the customer can obtain continuity of supply from the
          Licensee.

4.   Paragraph 3 shall not apply where:

     (a)  the customer has informed the Licensee that he does not wish to
          continue to be supplied by it after the expiry of the existing
          contract; or

     (b)  it is not reasonable in all the circumstances for the Licensee to be
          required to continue to supply that customer and the Licensee has (at
          least 30 days before the contract was due to expire) both notified the
          customer to that effect and informed him that he must make
          arrangements to obtain a supply from another Electricity Supplier.

                                      193
<PAGE>
 
5.   Where a Designated Supply Contract allows for its unilateral variation (in
     any respect) by the Licensee and is so varied to the significant
     disadvantage of the customer, the Licensee shall within 10 days of the
     variation give to the customer written notice:

     (a)  of the variation;

     (b)  of the customer's right to terminate the contract; and

     (c)  of the effect of paragraph 6.

6.   Where a customer gives to the Licensee a valid notice of termination within
     14 days of receiving notice under paragraph 5, the Licensee shall treat the
     variation as ineffective and shall neither enforce nor take advantage of
     it.

7.   Where the Licensee believes that any of its customers no longer occupies or
     is about to vacate Designated Premises to which it supplies electricity, it
     shall as soon as reasonably practicable provide any new occupier of those
     premises with an accurate summary of the Principal Terms of contracts it
     will make available to him.

CONDITION 37:  SECURITY DEPOSITS
- --------------------------------


1.   The Licensee shall not, in respect of the supply of electricity under any
     Designated Supply Contract, require a deposit:

     (a)  where the customer is prepared to be supplied through a prepayment
          meter and it is reasonably practicable in all the circumstances
          (including in particular the risk of loss or damage) for the Licensee
          to provide such a meter; or

     (b)  where it is otherwise unreasonable in all the circumstances to do so.

2.   Any deposit required of a Designated Customer may be 1 1/2 times the value
     of the average quarterly consumption of electricity reasonably expected at
     the relevant premises, or more if that is reasonable in all the
     circumstances.

3.   Where the Licensee requires a deposit of a Designated Customer it shall at
     the same time inform that customer of the effect of paragraphs 5 and 7.

4.   Where the Licensee holds any deposit it shall pay interest, at a rate it
     shall fix from time to time with the approval of the Director, on every sum
     of 50p deposited for every 3 months during which that sum is held.

5.   Subject to paragraph 6, any deposit given by a Designated Customer shall be
     repaid (with interest) by the Licensee:

     (a)  within 14 days where, in the previous 12 months, the customer has paid
          all charges for electricity supplied within 28 days of each written
          demand made; or

     (b)  as soon as reasonably practicable, and in any event within 1 month,
          where the Licensee has ceased to supply the customer and the customer
          has paid all charges for electricity supplied.

                                      195
<PAGE>
 
6.   Sub-paragraph 5(a) shall not apply where it is reasonable in all the
     circumstances for the Licensee to retain the deposit.

7.   Any dispute arising under this Condition between the Licensee and a
     Designated Customer may be referred by either party to the Director. The
     Director shall determine any such dispute, following such practice and
     procedure as he considers appropriate.

                                      196
<PAGE>
 
CONDITION 38:  TERMINATION OF CONTRACTS ON NOTICE
- -------------------------------------------------


1.   Each Designated Supply Contract shall contain a term allowing the customer
     to terminate such contract at any time by:

     (a)  giving to the Licensee a valid notice of termination; and

     (b)  subject to paragraph 6, paying to the Licensee on demand a termination
          fee.

2.   A notice of termination is valid where it is given at least 28 days in
     advance of the date on which it is to take effect and where, not later than
     that date, the requirements of paragraphs 3 and (unless the Licensee
     expressly agrees to waive it) 4 are satisfied.

3.   The requirement of this paragraph is that either:

     (a)  another Electricity Supplier commences a supply of electricity to the
          relevant premises; or

     (b)  the relevant premises are cut off because the customer at those
          premises has ceased to require a supply.

4.   The requirement of this paragraph is that no charges for electricity
     supplied to the customer (whether at the relevant premises or at any
     premises previously occupied by him), having been demanded in writing prior
     to the notice of termination being given, remain owing to the Licensee more
     than 28 days after that demand was made.

5.   Each Designated Supply Contract shall provide that a notice of termination
     which is not valid shall not be effective to terminate such contract.

6.   A termination fee shall not be demanded of a customer where:

     (a)  the contract was terminated under any provision of Condition 39;

                                      197
<PAGE>
 
     (b)  the contract was a contract of indefinite length, and was terminated
          other than during a fixed term period;

     (c)  the Licensee notified the customer, under paragraph 5 of Condition 36,
          of a unilateral variation of the contract and the customer gave notice
          of termination in accordance with paragraph 6 of that Condition; or

     (d)  the contract was a contract to which paragraph 4 of Condition 39
          applied and the Licensee did not, before entering into it, take all
          reasonable steps to draw the attention of the customer to the effect
          of the term set out at that paragraph.

7.   Where a termination fee is payable, it shall be of an amount not greater
     than that which the Licensee may in all the circumstances reasonably
     require.

                                      198
<PAGE>
 
CONDITION 39:  TERMINATION OF CONTRACTS IN SPECIFIED CIRCUMSTANCES
- ------------------------------------------------------------------


1.   Each Designated Supply Contract shall provide that the contract will
     terminate:

     (a)  on the date on which the customer ceases to own or occupy the relevant
          premises, having given the Licensee at least 2 working days' notice of
          that date; or

     (b)  where the customer has ceased to own or occupy the premises without
          giving the Licensee at least 2 working days' notice, on the first in
          time of:

          (i)   the second working day after he has given notice to the
                Licensee;

          (ii)  the next day on which the meter is due to be read; and

          (iii) the date on which any subsequent owner or occupier enters into a
                contract or tariff agreement for the supply of electricity to
                the premises.

2.   Each Designated Supply Contract shall provide that where it is terminated
     by virtue of a term included in the contract in compliance with paragraph
     1, the customer shall remain liable for any charges for the supply of
     electricity until the date of termination.

3.   Each Designated Supply Contract shall provide that it may be terminated
     immediately by either party at any time after the Director or the Secretary
     of State has revoked this Licence.

4.   Any Designated Supply Contract which:

     (a)  provides for the Licensee to supply electricity for a specified period
          of more than 12 months; or

     (b)  contains an initial fixed term period, shall provide that it may be
          terminated immediately by the customer at any time within 5 working
          days of the date of the contract.

                                      199
<PAGE>
 
     Where a Designated Supply Contract is for both the supply of electricity
     and the provision of goods or services:

     (a)  any reference in the Contract Terms Conditions to its termination is a
          reference to its termination in respect of the supply of electricity
          alone; and

     (b)  on its termination by virtue of any provision of the Contract Terms
          Conditions, the Licensee may require the customer to give any
          reasonable security for his future compliance with the contract for
          the provision of goods or services.

CONDITION 40:  ASSIGNMENT OF OUTSTANDING CHARGES
- ------------------------------------------------


1.   This Condition shall apply where:

     (a)  the Licensee has commenced the supply of electricity to Domestic
          Premises at which a supply was previously given to its customer by the
          Previous Supplier;

     (b)  the customer has failed to pay, within 28 days of receiving a demand
          in writing, any charges due from him to the Previous Supplier for the
          supply of electricity at those premises;

     (c)  that failure occurred after either the Previous Supplier was informed
          of the change of supplier or the Licensee commenced supply to the
          premises (whichever is the earlier);

     (d)  the Previous Supplier has given written notice to the customer that it
          proposes to assign the debt to the Licensee, which may be entitled to
          reclaim from him its costs in recovering the debt; and

     (e)  the Licensee has  received  from the Previous  Supplier a notice in
          accordance with paragraph 2.

2.   A notice in accordance with this paragraph is one which:

     (a)  is given at least 14 days after the notice referred to at sub-
          paragraph 1(d) and is received by the Licensee within 90 days of it
          commencing a supply to the premises;

     (b)  specifies the amount of the debt which remains unpaid;

     (c)  states that the Previous Supplier has used all reasonable endeavours
          to recover the debt, which remains unpaid at least 42 days after being
          demanded in writing; and

     (d)  states that the Previous Supplier intends to assign to the Licensee
          the debt, up to a maximum sum of one-third of the value (calculated in
          accordance with the charges 

                                      201
<PAGE>
 
          of the Previous Supplier to the customer immediately before it ceased
          to supply him) of the average annual consumption reasonably expected
          of the customer.

3.   Where this Condition applies the Licensee shall, within 60 days of
     receiving a notice under paragraph 2 and in consideration of the assignment
     of the debt, pay to the Previous Supplier the sum specified under sub-
     paragraph 2(d) (less, where they cannot be reclaimed from the customer, its
     reasonable costs of recovering that debt).

4.   For the purposes of this Condition, a customer shall not be regarded as
     being in debt to the Previous Supplier to the extent to which that debt is
     genuinely in dispute.

5.   In this Condition:

     "Previous Supplier"          means, in relation to any premises,
                                  the Electricity Supplier which supplied
                                  electricity to those premises immediately
                                  prior to the commencement of supply by the
                                  Licensee.

CONDITION 41:  MODIFICATION OF PROVISIONS UNDER CONDITIONS 38 AND 40
- --------------------------------------------------------------------


1.   In this Condition, the "relevant provisions" are the provisions of
     paragraph 4 of Condition 38 and Condition 40 of this Licence (or any of
     them).

2.   Where the Director considers (having regard to any representations made to
     him) that in any specified class of cases the relevant provisions do not
     fulfil the requirements of paragraph 4, he may direct that they shall cease
     to have effect in that class of cases.

3.   Where a direction under paragraph 2 has been made and the Director
     considers (having regard to any representations made to him) that in the
     specified class of cases the relevant provisions would fulfil the
     requirements of paragraph 4, he may direct that they shall again have
     effect in those cases.

4.   The requirements of this paragraph are that, in the specified class of
     cases, the operation of the relevant provisions:

     (a)  significantly reduces the number of unrecovered debts otherwise to be
          expected; or

     (b)  involves expenditure in debt recovery which is less than the reduction
          in the value of unrecovered debts which it achieves.

5.   Any direction under paragraphs 2 or 3 shall be made by a notice given to
     the Relevant Parties which shall specify:

     (a)  the relevant provisions to which it applies;

     (b)  the class of cases to which it applies; and

     (c)  the date on which it shall have effect (being, in a direction under
          paragraph 3, at least 3 months after the notice is given).

     "Relevant Parties"                 means the Licensee, all other
                                        Electricity Suppliers, the Electricity
                                        Consumers' Committees and such other
                                        persons or bodies as in the opinion of
                                        the Director are representative of those
                                        likely to be affected by a revision to
                                        the relevant provisions.

                            TERMS AS TO REVOCATION
                            ----------------------


1.   The Secretary of State may at any time revoke this Licence by not less than
     30 days' notice in writing to the Licensee:

     (a)  if the Licensee agrees in writing with the Secretary of State that
          this Licence should be revoked;

     (b)  if any amount payable under Condition 29 is unpaid 30 days after it
          has become due and remains unpaid for a period of 14 days after the
          Secretary of State has given the Licensee notice that the payment is
          overdue. Provided that no such notice shall be given earlier than the
          sixteenth day after the day on which the amount payable became due;

     (c)  if the Licensee fails to comply with a final order (within the meaning
          of Section 25 of the Act) or with a provisional order (within the
          meaning of that Section) which has been confirmed under that Section
          and (in either case) such failure is not rectified to the satisfaction
          of the Secretary of State within 3 months after the Secretary of State
          has given notice of such failure to the Licensee. Provided that no
          such notice shall be given by the Secretary of State before the
          expiration of the period within which an application under Section 27
          of the Act could be made questioning the validity of the final or
          provisional order or before the proceedings relating to any such

         SUPPLEMENTARY PROVISIONS OF THE CHARGE RESTRICTION CONDITIONS
         -------------------------------------------------------------

                                    PART A
                                    ------

                          PRINCIPLES FOR ATTRIBUTION
                          --------------------------


     General Principles
     ------------------

A1.  Where, for the purposes of the charge restriction conditions, a share of
     costs borne by the Licensee requires to be attributed to any part of the
     market, the Licensee shall make that attribution on a basis which ensures
     that no more than a fair proportion of those costs, reflecting the costs
     incurred by the Licensee in supplying that part of the market, are so
     attributed.

A2.  The following paragraphs of this Part of Schedule 3 are without prejudice
     to paragraph A1.

     Fossil Fuel Levy and payments in lieu thereof
     ---------------------------------------------

A3.  The fossil fuel levy requiring to be attributed to supplies to Designated
     Customers shall be attributed on the basis of the amount of the levy
     incorporated in the prices actually charged or to be charged by the
     Licensee on supplies to such customers in the relevant year in respect of
     which the attribution falls to be made. Amounts in lieu of the fossil fuel
     levy in respect of purchases of electricity other than leviable electricity
     requiring to be calculated and then attributed to supplies to Designated
     Customers in any relevant year for the purposes of Condition 3B shall:

     (a)  be calculated as being such amounts as correspond to the lesser of:

                                      209
<PAGE>
 
          (i)    the premium actually payable (measured on an accruals basis) by
                 the Licensee during the relevant year on purchases of
                 electricity other than leviable electricity as representing the
                 benefit to the Licensee of being able to treat such electricity
                 as being other than leviable electricity for the purposes of
                 Section 33 of the Act and Regulations thereunder; and

          (ii)   the additional amount that would have been payable (measured on
                 an accruals basis) by the Licensee in respect of the fossil
                 fuel levy pursuant to Regulations made under Section 33 of the
                 Act had such electricity been leviable electricity; and

     (b)  be attributed to supplies to Designated Customers pro rata to the
          amount which the quantity supplied to Designated Customers bears to
          the total quantity supplied (in each case in the relevant year in
          respect of which the attribution falls to be made) or on the basis of
          the amount referred to in paragraph (a) incorporated in the prices
          actually charged or to be charged by the Licensee on supplies to such
          customers in the relevant year in respect of which the attribution
          falls to be made or on such other basis of attribution as the Licensee
          shall previously have agreed with the Director.

     Transmission connection point charges and Remote Transmission Asset rentals
     ---------------------------------------------------------------------------

A4.  The transmission connection point charges and Remote Transmission Asset
     rentals requiring to be attributed between the regulated quantity
     distributed and other quantities distributed shall be attributed in
     proportion to the transmission connection point and Remote Transmission
     Asset capacity required for the purpose of distributing those quantities.

     Distribution losses
     -------------------

A5.  Where an amount (in units) in respect of distribution losses requires to be
     calculated and attributed in respect of EHV units and units distributed by
     the Licensee for the purpose of supply to premises outside the Licensee's
     authorised area, such calculation and attribution shall be made
     consistently with the principles underlying the schedule of adjustment
     factors referred to at sub-paragraph (b) of paragraph 3 of Condition 8.

                                      210

     Information to be provided by Licensee
     --------------------------------------

A6.  The Licensee shall following the end of each relevant year furnish to the
     Director, as being one of the specified items to be included in the
     statement referred to at paragraph 7 of Condition 3E, a statement of the
     actual attribution of electricity purchase costs between regulated and
     other customers and reconciling the attribution with any statements made in
     respect of the relevant year under paragraph 2 of Condition 3E, and a
     statement confirming that the calculation of amounts in lieu of the fossil
     fuel levy and the attribution of the fossil fuel levy, amounts in lieu
     thereof, the transmission connection point charges, the Remote Transmission
     Asset rentals and of distribution losses was made in accordance with the
     provisions of this Part of Schedule 3, accompanied (where appropriate) by

          (i)   a statement of the total amounts attributed to regulated
                Designated Customers and other customers; and

          (ii)  copies of statements prepared under paragraph 2 of Condition 3E
                and an explanation of the basis therefor.

A7.  Where the Director is satisfied that the basis of calculation or
     attribution (as the case may be) used by the Licensee is not in conformity
     with paragraph A1, the Director may issue directions specifying an
     alternative basis of calculation or attribution, and the basis of
     calculation or attribution by the Licensee (as the case may be) shall be
     adjusted accordingly with effect from the date of issue of the directions
     or (subject to paragraph 10 of Condition 3E) such other date as may be
     specified in those directions.

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

B1.  EHV premises shall comprise:

     (a)  in relation to premises connected to the Licensee's distribution
          system as at the date this Licence enters into force, those premises
          specified in the list of EHV premises notified in writing to the
          Director by the Licensee within twenty-eight days after this Licence
          enters into force; and

     (b)  in relation to premises connected to the Licensee's distribution
          system which are either first connected or (having been previously
          connected) have had their connections materially altered following the
          date this Licence enters into force, means premises connected to the
          Licensee's distribution system at a voltage at or higher than 22
          kilovolts or at a sub-station with a primary voltage of 66 kilovolts
          or above.

B2.  The Licensee shall following the end of each relevant year furnish to the
     Director, as being one of the specified items to be included in the
     statement referred to at paragraph 7 of Condition 3E, a statement listing
     any changes in the premises falling to be treated as EHV premises.

B3.  Where the Director is satisfied that any premises treated by the Licensee
     as EHV premises should not in conformity with sub-paragraph B1 (b) above be
     so treated, the Director may issue directions to that effect, and such
     premises shall cease to be treated as EHV premises from the date of issue
     of the directions or (subject to paragraph 10 of Condition 3E) such other
     date as may be specified in those directions.

                               EXCLUDED SERVICES
                               -----------------


     Distribution Business
     ---------------------

C1.  There may be treated as excluded services provided by the Licensee in its
     Distribution Business such services in respect of which charges are made
     which:

     (a)  do not fall within paragraph C2 of this Part; and

     (b)  may (subject to paragraph C9) be determined by the Licensee as falling
          under one of the principles set out in paragraphs C3 to C6 of this
          Part.

C2.  No service provided by the Licensee as part of its Distribution Business
     shall be treated as an excluded service insofar as it consists of the
     provision of services remunerated under the use of system charges in
     accordance with paragraph 3 of Condition 8 including (without prejudice to
     the foregoing):

          (i)    (subject to paragraph C3 of this Part) the transport of
                 electricity;

          (ii)   the carrying out of works for the installation of electric
                 lines or electrical plant (not otherwise payable in the form of
                 connection charges);

          (iii)  the carrying out of works or the provision of maintenance or
                 repair or other services for the purpose of enabling the
                 Licensee to comply with Conditions 9, 11 and 13, the
                 Electricity Supply Regulations 1988 or any regulations made
                 under Section 29 of the Act or any other enactment relating to
                 safety or standards applicable in respect of the Distribution
                 Business; and

          (iv)   (subject to paragraph C5 of this Part) the provision,
                 installation and maintenance of any meters, switchgear or other
                 electrical plant (not being part of connection charges).

                                      213
<PAGE>
 
C3.  The Licensee may treat as being an excluded service for the purposes of its
     Distribution Business the transport of:

     (a)  units of electricity not consumed in the Licensee's authorised area;
          or

     (b)  EHV units.

C4.  Charges of the type described in paragraph 4 of Condition 8 and borne in
     accordance with the principles set out in paragraph 7 of Condition 8 by any
     person as connection charges, and charges in respect of the statements
     referred to in paragraph 8 of Condition 8, may each be treated as excluded
     services for the purposes of the Distribution Business.

C5.  A service provided by the Licensee as part of its Distribution Business may
     be treated as an excluded service insofar as it consists in the provision
     of services (including metering, electric lines or electrical plant) for
     the specific benefit of any third party requesting the same and not made
     available by the Licensee as a normal part of its Distribution Business
     remunerated by use of system charges including (without prejudice to the
     foregoing):

          (i)    special metering (including "time of day" metering) to
                 facilitate energy saving programmes for the benefit of
                 customers requesting the same;

          (ii)   charges for moving mains, services or meters forming part of
                 the Licensee's distribution system to accommodate extension, 
                 re-design or re-development of any premises on which the same
                 are located or to which they are connected;

          (iii)  the provision of electric lines and electrical plant (a)
                 insofar as the same are required for the specific purpose of
                 enabling the provision of top-up or standby supplies or sales
                 of electricity or (b) to provide a higher degree of security
                 than is required for the purposes of complying with Condition
                 9;

                                      214
<PAGE>
 
          (iv)   the amount by which charges for the provision of prepayment
                 meters to customers exceed charges for the provision of
                 standard meters for such customers; and

          (v)    special metering or telemetry or data processing equipment for
                 the purpose of enabling any person who is a party to the
                 Pooling and Settlement Agreement to comply with its obligations
                 in respect of metering thereunder, or for the performance by
                 the Licensee of any service in relation thereto.

C6.  There may be treated as an excluded service for the purposes of the
     Distribution Business, charges for the relocation of electric lines or
     electrical plant and the carrying out of works associated therewith
     pursuant to a statutory obligation (other than under Section 9 (1) or
     Section 16 of the Act) imposed on the Licensee.

     Supply Business
     ---------------

C7.  Subject to paragraph C9, a service provided by the Licensee as part of its
     Supply Business may be treated as an excluded service insofar as it
     consists of the provision of services for the specific benefit of customers
     requesting the same and not made available by the Licensee as a normal part
     of such Business. For the avoidance of doubt, the provision of facilities
     for prepayment may not be treated as an excluded service except the
     provision of prepayment meters as an excluded service by the Distribution
     Business.

     Information to be provided to the Director
     ------------------------------------------

C8.  The Licensee shall following the end of each relevant year furnish to the
     Director, as being one of the specified items to be included in the
     statement referred to at paragraph 7 of Condition 3E, details specifying
     separately the nature of all services provided as part of its Distribution
     Business or Supply Business by the Licensee and treated as excluded

     ----------

C9.  Where the Director is satisfied that in light of the principles set out in
     paragraphs C2 to C7 inclusive any service treated by the Licensee as an
     excluded service should not be so treated, the Director shall issue
     directions to that effect, and the service or services specified in the
     directions shall cease to be treated as excluded services from the date of
     issue of the directions or (subject to paragraph 10 of Condition 3E) such
     other date as may be specified in the directions.

                    REGULATED DISTRIBUTION UNIT CATEGORIES
                    --------------------------------------

D1.  The Licensee shall following the end of each relevant year furnish to the
     Director, as being one of the specified items to be included in the
     statement referred to at paragraph 7 of Condition 3E, details specifying
     separately those use of system charges in respect of which the Licensee has
     during the course of such year treated the units distributed as falling

     respectively.

D2.  The definition of LV1 units includes units distributed under the following
     tariffs:

          Domestic E7 day rate
          Quarterly non domestic E7 day rate
          Quarterly non domestic 3-rate evening, weekend and night tariff: day,

D5.  Notwithstanding the provisions of paragraphs D2 to D4 above, where the
     Director is satisfied that a tariff or tariffs in respect of which the
     Licensee has treated the units distributed as falling within one of the
     categories in paragraphs D2 to D4 above should not be so treated, the
     Director shall issue directions to that effect and the tariff or tariffs
     specified in the directions shall cease to be so treated from the date of
     issue of the directions or (subject to paragraph 10 of Condition 3E) such
     other date as may be specified in the directions and shall with effect from
     such date be treated in such manner as may be specified in the directions.

            CALCULATION OF FACTOR IN RESPECT OF DISTRIBUTION LOSSES
            -------------------------------------------------------

E1.  For the purposes of calculation of the terms ALt and Lt as used in
     paragraph 1 of Condition 3A shall each be determined for relevant years
     commencing on or after 1st April 1995 using the consistent methodological
     basis set out in paragraphs E2 to E5 below.

     Consistent methodological basis for determination of  ALt and L
     ---------------------------------------------------------------

E2.  Adjusted distribution losses shall be determined as being the difference
     between adjusted grid supply point purchases and adjusted units
     distributed.

E3.  Units metered on entry to the Licensee's distribution system shall be
     adjusted to obtain adjusted grid supply point purchases by:

     (a)  excluding that number of units which is equal to the sum of:

          (i)    EHV units; and

          (ii)   units distributed by the Licensee for the purpose of supply to
                 premises outside the Licensee's authorised area; and

          (iii)  an amount in respect of distribution losses between the grid
                 supply point and the exit point attributable to the units
                 referred to in (i) and (ii) above, as determined in accordance
                 with paragraph A5 in Part A of Schedule 3; and

                                      219
<PAGE>
 
     (b)   including an amount (in units) to represent the effect of units
           entering the Licensee's distribution system otherwise than at grid
           supply points, being the difference between the number of units so
           entering and the number of units that would have been required to
           have entered at grid supply points in their absence (such latter
           number of units being calculated consistently with the principles
           underlying the schedule of adjustment factors in respect of
           distribution losses referred to at sub-paragraph (b) of paragraph 3
           of Condition 8).

E4.  For so long as units are metered on entry to the Licensee's distribution
     system at bulk supply points instead of at grid supply points, such units
     shall be calculated by:

     (i)   applying the procedures in paragraph E3 as if all references to units
           metered at grid supply points were to units metered at bulk supply
           points; and

     (ii)  grossing-up units metered at the bulk supply points by the relevant
           grid supply point conversion factor being either:

           (a)   0.5 per cent of the units metered at the bulk supply points; or

           (b)   such other factor to take account of losses occurring between
                 the grid supply points and the bulk supply points as the
                 Licensee may with the prior approval of the Director determine
                 to be appropriate.

E5.  Adjusted units distributed shall be obtained by:

     (a)   calculating all units distributed by the Licensee metered at exit
           points on leaving the Licensee's distribution system; and

     (b)   deducting therefrom EHV units and units distributed for the purpose
           of supply to premises outside the Licensee's authorised area; and

     (c)   adding thereto an amount equal to the units consumed on the
           Licensee's premises in the authorised area (insofar as not otherwise
           taken into account in determining units distributed under sub-
           paragraph (a) above).

     Initial relevant loss percentage in the term ALt
     ------------------------------------------------

E6.  In the first relevant year, the initial relevant loss percentage in the
     term ALt shall (consistently with the methodology set out in paragraphs E2
     to E5 above) be determined as being:

          adjusted GSP purchase units less adjusted units distributed
          -----------------------------------------------------------
                          adjusted units distributed

     where adjusted GSP purchase units are calculated as provided in paragraph
     E7 and adjusted units distributed are calculated as provided in paragraph
     E8.

E7.  Adjusted GSP purchase units shall be calculated in accordance with the
     procedures successively described in the following sub-paragraphs:

     (a)  the actual losses in each of relevant years t-1, t-2 and t-3 (the
          "historic losses") shall be calculated as the difference in each of
          those years between units purchased at entry points to the Licensee's
          distribution system and units sold;

     (b)  the historic loss percentage shall be calculated as the proportion
          (expressed as a percentage) which the aggregate historic losses were
          of the aggregate units purchased at entry points to the Licensee's
          distribution system, in each case over the three relevant years t-1 to
          t-3;

     (c)  the total number of units sold in relevant year t-1 shall be grossed
          up by the historic loss percentage ("BSP purchase units"); and

     (d)  the figure for BSP purchase units resulting from sub-paragraph (c)
          shall be adjusted to obtain adjusted GSP purchase units in accordance
          with the provisions of paragraphs E3 and E4 above.

E8.  Adjusted units distributed shall be calculated by applying the methodology
     of paragraph E5 in respect of those units referred to in sub-paragraphs (a)
     to (c) of paragraph E5 in relevant year t-1.

                                      221

      Information to be provided to the Director
      ------------------------------------------

E9.   The Licensee shall within three months after the entry into force of this
      Licence furnish to the Director a statement showing the initial relevant
      loss percentage and the underlying calculations.

E10.  The Licensee shall, following the end of each relevant year, furnish to
      the Director, as being one of the specified items to be included in the
      statement referred to at paragraph 7 of Condition 3E, a statement showing
      adjusted distribution losses for that relevant year, accompanied by the
      underlying calculations and (where appropriate) an explanation of any
      changes in the basis of calculation or estimation thereof.

E11.  Where the Director is satisfied that any statement or underlying
      calculation provided has not been drawn up in conformity with paragraphs
      E2 to E8 above, the Director may issue directions, and the statement or
      underlying calculation shall be adjusted with effect from the date of
      issue of the directions or (subject to paragraph 10 of Condition 3E) such
      other date as may be specified in the directions.

     (b)  in respect of premises occupied by a new customer seeking a supply
          from the licensee the relevant demand in megawatts shall be calculated
          by reference to the average maximum monthly demand which might
          reasonably be expected in the three months of highest maximum demand
          over a twelve-month period at premises having similar demand
          characteristics to the premises occupied by such new customer.

3.   Subject to paragraph 4 below, if at any time during the franchise period
     the relevant demand in megawatts (calculated in accordance with paragraph 2
     above) at any single premises to which a supply is given by the licensee in
     accordance with the provisions of this Condition should fall below the
     franchise limit the licensee may, notwithstanding such fact, continue to
     supply such premises without being in breach of this Condition until such
     time as:


     (a)  any contract existing between the licensee and the customer occupying
          such premises is determined by effluxion of time or otherwise; or


                                      15
<PAGE>
 
     (b)  the supply arrangements between the licensee and the customer
          occupying such premises shall for any other reason be terminated.

4.   Save where the Director otherwise agrees, if (having regard to the basis of
     assessment referred to in paragraph 2(b) above) the relevant demand in
     megawatts of a customer who was a new customer at the time of commencement
     of supply by the licensee should, in the first twelve-month period for
     which figures are available, prove to be less than was reasonably expected
     of such customer and to fall below the franchise limit, the licensee shall
     cease to supply such customer.

5.   Not withstanding paragraph 1, the licensee may supply electricity to single
     premises at which the relevant demand in megawatts is below the franchise
     limit where such single premises are specified for the purposes of this
     licence by the Director with the prior approval of the Secretary of State.

6.   For the purposes of paragraph 2(a), where the average calculated as there
     provided, but ignoring for this purpose the reference to normal operating
     conditions, was no more than 10 per cent. higher than the average
     (calculated in the same manner) over the twelve-month period preceding the
     twelve-month period referred to in paragraph 2(a), the maximum monthly
     demands from which the average was derived shall be presumed to have
     occurred under normal operating conditions.

7.   Any dispute arising under the provisions of this Condition between the
     licensee and any authorised electricity operator or any person requiring a
     supply of electricity from the licensee may be referred to the Director and
     the Director shall determine whether the premises in respect of which the
     customer requires a supply to be given fall within the franchise limit.

8.   In this Condition:

          "existing customer"                means any person occupying premises
                                             to which a supply is being given by

Schedule

Condition 2 of each licence which has been granted under section 6(2)(a) of the
Act (other than the licence granted to London Electricity plc) shall be modified
by the addition of the following two paragraphs after paragraph 7 -

7A.  For the purpose of this Condition occupation of any premises by an
     affiliate of a person shall be deemed to be occupation by that person.

7B.  (1)  In this paragraph -

          "customer B" means the customer for the time being of the licensee in
          respect of premises A;

          "permitted quantity" means 10 per cent of the quantity of electricity
          supplied by the licensee to customer B in respect of premises A in the
          relevant year;

          "premises A" means a site or building which, if in the occupation of a
          single customer, would be capable of being single premises; and

          "relevant year " means the period of 12 months commencing on the date
          upon which the licensee starts to supply premises A and (if such
          supply is provided for a continuous period exceeding 12 months) each
          anniversary of that date until such supply shall cease .

     (2)  Where during a relevant year -

          (i)   premises A are occupied by more than one person;

          (ii)  customer B supplies the other person or persons who are in
                occupation of premises A or supplies one or more of such persons
                who supply the other occupiers;

          (iii) each of the persons referred to in subparagraph (ii) who
                provides a supply is exempt by or under an Order under section 5
                of the Act from the requirement to hold a licence to supply; and

          (iv)  customer B does not supply an aggregate quantity of electricity
                to such other occupiers in any relevant year which may
                reasonably be expected to exceed or actually exceeds the
                permitted quantity,

the occupation of premises A by the persons other than customer B shall be
deemed to be occupation by customer B.

     (3)  The licensee shall, at: the request of the public electricity supplier
          in whose authorised area premises A are situated, provide not more
          than once in any period of 3 months in a relevant year, evidence to
          the supplier that the licensee reasonably believes that the aggregate
          quantity of electricity


                                       9
<PAGE>
 
          expected to be supplied by customer B during the relevant year will
          not exceed the permitted quantity including, where at the date of such
          request any such supply has been provided during the relevant year,
          evidence as to the quantity so supplied.

     (4)  Where customer B has supplied a quantity of electricity to such other
          occupiers which in aggregate exceeds the permitted quantity, the
          licensee shall pay to the public electricity supplier in whose
          authorised area premises A are situated a sum calculated by
          multiplying the number of units by which the actual supply to such
          other occupiers exceeds the permitted quantity by 5 per cent of the
          standard tariff price per unit charged by that public electricity
          supplier for customers of the type or types of such other occupiers
          (but excluding any standing charge or other charge not fixed solely by
          reference to the number of units consumed) or in the absence of
          agreement as to the appropriate tariff such rate as may be determined
          by the Director at the request of the licensee or the public
          electricity supplier.

     (5)  For the purposes of this paragraph there shall be disregarded -

          (i)   the quantity of electricity supplied by customer B to an
                occupier of premises A who has a relevant demand above the
                franchise limit;

          (ii)  the quantity of electricity supplied to customer B equal to the
                quantity supplied by customer B in accordance with subparagraph
                (i); and

          (iii) the occupation by the occupier (other than customer B) referred
                to in subparagraph (i).

     (6)  To the extent that, disregarding sub-paragraph (2), the licensee would
          have been permitted to provide a supply to customer B's premises under
          this Condition, the provisions of this paragraph shall not apply.

     that it would be unreasonable in all the circumstances for the direction to
     have effect on the dates specified therein in respect of any or all of
     those premises at which it has not yet had effect, then the Director may,
     subject to paragraph 9, withdraw or vary the direction in respect of the
     premises to be supplied or of the dates from which they may be supplied, or
     both.

8.   The considerations set out in this paragraph are:

     (a)  whether the interests of customers in general, and in particular the
          interests those occupying the premises specified in the direction,
          would be served by the withdrawal or variation of the direction;

     (b)  whether the interests of any Electricity Supplier, including the
          Licensee, would be or would be likely to be unfairly prejudiced by the
          withdrawal or variation of the direction, or by a failure to do so;

     (c)  the content of any representation made to the Director on the issue;
          and

     (d)  such information as is available to the Director concerning:

           (i) the manner in which arrangements for the supply of electricity to
               any premises to which this Condition applies have operated and
               are expected to operate;

          (ii) the likely ability of the Licensee to fulfil its obligations
               under its Licence with respect to the supply of electricity to
               any of the premises concerned; and

         (iii) the likely ability of each Relevant Public Electricity Supplier
               to comply with the requirements of its public electricity supply
               licence in respect of the supply of electricity by the Licensee
               to the premises concerned.
<PAGE>
 
9.   The Director shall not withdraw or vary a direction in respect of any
     premises when the date specified from which supply may commence is less
     than 14 days from the date of the withdrawal or variation, unless the
     Director has the agreement of the Licensee, or failing that agreement the
     agreement of no fewer than two-thirds of the Second Tier Suppliers to whom
     a direction applies in respect of the same premises and dates.

10.  When the Director withdraws or varies a direction in accordance with
     paragraph 7, he shall issue a notice of withdrawal or variation (as the
     case may be) and that notice shall have effect.

11.  The Director shall publish any direction, or any notice of withdrawal or
     variation  in such manner as in the opinion of the Director will secure
     adequate publicity for it.

12.  A direction or a variation or withdrawal of a direction made under this
     Condition shall not distinguish between the Licensee and other Second Tier
     Suppliers except to the extent that the distinction is appropriate in all
     the circumstances given:

     (a)  the information available to the Director in accordance with sub-
          paragraph 8(d)(ii); or

     (b)  where the Licensee is also a public electricity supplier, any failure
          by the Licensee to comply with the requirements of its public
          electricity supply licence, or with any agreement entered into in
          accordance with any such requirements, which adversely affects the
          ability of private electricity suppliers to supply electricity to
          customers within its authorised area.

          may specify; and

     (c)  containing terms in accordance with paragraphs 4 and 5 and such
          further terms as may be appropriate for the purposes of the agreement.

3.   The Licensee shall, subject to paragraphs 7 and 8, offer terms for an

     as the Licensee may reasonably require for the purpose of formulating the
     terms of its offer.

4.   Any offer to enter into an agreement made by the Licensee in accordance
     with paragraph 1 or 2 shall make detailed provision regarding:

     (a)  the carrying out of works (if any) required for the construction or
          modification of the entry point to connect the Licensee's System to
          the Transmission System or to any Distribution System or in connection

          electricity to be distributed in accordance with the agreement, and
          for the obtaining of any consents necessary for such purpose;

     (b)  the carrying out of works (if any) for the provision of electrical
          plant or for the extension or reinforcement of the Licensee's System
          which are required to be undertaken for the provision or modification
          of a connection to the Licensee's System or for use of system and the
          obtaining of any consents necessary for such purpose;

     (c)  the installation of appropriate meters or other apparatus (if any)
          required to enable the Licensee to measure electricity being accepted
          into the Licensee's system at the specified entry point and leaving
          such system at the specified exit points;

     (d)  the installation of such switchgear or other apparatus (if any) as
          may be required for interrupting the use of system should there be a
          failure by or for an Authorised Electricity Operator to provide
          electricity at its entry point on the Licensee's System for delivery
          to the person specified by the Authorised Electricity Operator from
          the exit points on such system;

     (e)  the date by which any works required so as to permit access to the
          Licensee's System (including for this purpose any works for its
          extension or reinforcement) shall be completed (time being of the
          essence unless otherwise agreed by the Authorised Electricity
          Operator); and

     (f)  the charges to be paid by the applicant for the provision of
          electrical plant, for connections or modification of connections to,
          or the extension or reinforcement of, the Licensee's System, for the
          installation of meters, switchgear or other apparatus and the removal
          of electrical plant, electric lines and meters following disconnection
          and for use of system which shall, unless manifestly inappropriate, be
          set in conformity with paragraph 5.

5.   The charges referred to in paragraph 4 to be contained in every agreement
     which is the subject of an offer by the Licensee shall be such that:
<PAGE>
 
     (a)  charges for the provision of electrical plant, connection charges,
          charges for modification of connections, charges for disconnection
          from the Licensee's System and the removal of electrical plant,
          electric lines and meters following disconnection or any charges for
          extension or reinforcement of the Licensee's System or for use of
          system are set at a level which will enable the Licensee to recover no
          more than:

          (i)  the appropriate proportion (taking account of the factors
               referred to in paragraph 6) of the costs directly or indirectly
               incurred by the Licensee; and

          (ii) a reasonable rate of return on the capital represented by such
               costs; and

     (b)  charges for the installation of meters, switchgear or other apparatus
          and for their maintenance shall not exceed the costs thereof and a
          reasonable rate of return on the capital represented by such costs.

6.   For the purpose of determining an appropriate proportion of the costs
     directly or indirectly incurred in carrying out works, the Licensee shall
     have regard to:

     (a)  the benefit (if any) to be obtained or likely in the future to be
          obtained by the Licensee or any other person as a result of the
          carrying out of such works whether by virtue of the provision of
          electrical plant, the reinforcement or extension of the Licensee's
          System, the provision of additional entry or exit points on such
          system or otherwise; and

     (b)  the ability or likely future ability of the Licensee to recoup a
          proportion of such costs from other persons.

7.   The Licensee shall not be obliged pursuant to this Condition to offer to
     enter into any agreement where, by reason of the capacity of the Licensee's
     System and the use made or reasonably expected to be made of it, the
     Licensee would be required to expand or reinforce the capacity of the
     Licensee's System.
<PAGE>
 
8.   The Licensee shall not be obliged pursuant to this Condition to offer to
     enter into any agreement if:.

     (a)  to do so would be likely to involve the Licensee being:

          (i)   in breach of the Grid Code;
          (ii)  in breach of any Distribution Code;
          (iii) in breach of the Electricity Supply Regulations 1988 or any
                regulations made under Section 29 of the Act; or
          (iv)  in breach of any other enactment relating to safety or standards
                applicable to the Licensee's System; or
     (b)  the person making the application does not undertake to be bound,
          insofar as applicable, by the terms of the Distribution Codes or the
          Grid Code from time to time in force; or

     (c)  in the case of an agreement for use of system, the person making the
          application ceases to be an Authorised Electricity Operator.

9.   For the purpose of paragraph 3, the period specified shall be:

     (a)  in the case of persons seeking use of system only, 28 days; and

     (b)  in the case of persons seeking the provision or modification of a
          connection or use of system in conjunction with connection, 3 months.

10.  The Licensee shall within 28 days following receipt of a request from any
     person, give or send to such person such information in the possession of
     the Licensee as may be reasonably required by such person for the purpose
     of completing paragraph 8 of Part I and paragraphs 2(v) and (vi) of Part 2
     of Schedule 2 to The Electricity (Application for Licences and Extensions
     of Licences) Regulations 1990 or such provisions to like effect contained
     in any further regulations then in force made pursuant to section 6(3) of
     the Act.

11.  If, after a period which appears to the Director to be reasonable for the
     purpose, the Licensee has failed to enter into an agreement with any person
     entitled or claiming to be entitled thereto pursuant to an application in
     accordance with this Condition, the Director may pursuant to section
     7(3)(c) of the Act, on the 
<PAGE>
 
     application of such person or the Licensee, settle any terms of the
     agreement in dispute between the Licensee and that person in such manner as
     appears to the Director to be reasonable having (in so far as relevant)
     regard, in particular, to the following considerations

     (a)  that the person should pay to the Licensee the whole or an
          appropriate proportion (as determined in accordance with paragraph 6)
          of the costs directly or indirectly incurred by the Licensee in the
          carrying out of any works or in providing or doing any other thing
          under the agreement in question together with a reasonable rate of
          return on the capital represented by such costs, to be calculated in
          accordance with the principles set out in paragraph 5;

     (b)  that the performance by the Licensee of its obligations under the
          agreement should not cause it to be in breach of any Condition of this
          Licence;

     (c)  that any methods by which the Licensee's System is connected to the
          Transmission System or to any Distribution System accords with good
          engineering principles and practices; and

     (d)  that the terms of agreements entered into by the Licensee pursuant to
          an application in accordance with this Condition should be, so far as
          circumstances allow, as similar in substance and form as is
          practicable.

12.  If any person wishes to proceed on the basis of an agreement as settled by
     the Director, the Licensee shall forthwith enter into and implement such
     agreement.

13.  If either party to such agreement proposes to vary the contractual terms
     of any agreement for the provision or modification of a connection to the
     Licensee's System or for use of system entered into pursuant to this
     Condition in any manner provided for under such agreement, the Director
     may, at the request of that party, settle any dispute relating to such
     variation in such manner as appears to the Director to be reasonable.

Condition 2: Restriction on supply to certain premises


1. Save as provided in paragraphs 3 and 5 below the licensee shall not during
the franchise period supply electricity to any single premises at which the
relevant demand in megawatts is at or below the franchise limit.

2. In determining for the purposes of this Condition whether any single premises
falls within the franchise limit the licensee shall have regard to the following
bases of assessment:

          (a) in respect of premises occupied by existing customers the relevant
     demand in megawatts shall be calculated as an average of the maximum
     monthly demands under normal operating conditions at such single premises
     supplied by one or more authorised electricity operators and/or the
     licensee in the 3 months of highest maximum demand as recorded over the
     most recent 12 month period in respect of which figures are available; and

          (b) in respect of premises occupied by a new customer seeking a supply
     from the licensee the relevant demand in megawatts shall be calculated by
     reference to the average maximum monthly demand which might reasonably be
     expected in the 3 months of highest maximum demand over a 12 month period
     at premises having similar demand characteristics to the premises occupied
     by such new customer.

2A. For the purposes of paragraph 2, if any electricity which has been or is to
be supplied by the licensee to any single premises ("premises A") is or will be
on-supplied by another person from premises A to one or more single premises
("premises B") then:

          (a) If the on-supply to premises B from premises A was made on 31st
     March 1990 by that other person pursuant to an agreement for that other
     person to supply premises B which was subsisting on that date that demand
     at premises B which is met by such on-supply from premises A may be
     regarded as part of the relevant demand in megawatts at premises A; and

          (b) save as provided in sub-paragraph (a) above, that demand at
     premises



                                       12
<PAGE>
 
     B which is met by such on-supply from premises A shall not be regarded as
     part of the relevant demand in megawatts at premises A.

3. Subject to paragraph 4, if at any time during the franchise period the
relevant demand in megawatts (calculated in accordance with paragraph 2 and 2A)
at any single premises to which a supply is given by the licensee in accordance
with the provisions of this Condition should fall to or below the franchise
limit the licensee may, notwithstanding such fact, continue to supply such
premises without being in breach of this Condition until such time as:

          (a) any contract existing between the licensee and the customer
     occupying such premises is determined by effluxion of time or otherwise; or

          (b) the supply arrangements between the licensee and the customer
     occupying such premises shall for any other reason be terminated.

4. Save where the Director otherwise agrees, if (having regard to the basis of
assessment referred to in paragraph 2(b)) the relevant demand in megawatts of a
customer who was a new customer at the time of commencement of supply by the
licensee should, in the first 12 month period for which figures are available,
prove to be less than was reasonably expected of such customer and to fall to or
below the franchise limit, the licensee shall cease to supply such customer.

5. Notwithstanding paragraph 1, the licensee may supply electricity to single
premises at which the relevant demand in megawatts is at or below the franchise
limit where such single premises are specified for the purposes of this licence
by the Director with the prior approval of the Secretary of State.

6. For the purposes of paragraph 2(a), where the average calculated as there
provided, but ignoring for this purpose the reference to normal operating
conditions, was no more than 10 per cent higher than the average (calculated in
the same manner) over the twelve-month period preceding the twelve-month period
referred to in paragraph 2(a), the maximum monthly demands from which the
average was derived shall be presumed to have occurred under normal operating
conditions.

7. Any dispute arising under the provisions of this Condition between the
licensee and any authorised electricity operator or any person requiring a
supply of electricity from the licensee may be referred to the Director and the
Director shall 



                                       13

Act, on the application of such person or the licensee, settle any terms of the
agreement in dispute between the licensee and the person in such manner as
appears to the Director to be reasonable having (insofar as relevant) regard, in
particular, to the following considerations:


     (a) that the person should pay to the licensee the whole or an appropriate
     proportion (as determined in accordance with paragraph 5 of Condition 3] of

2. Not later than 3 months before the end of each financial year, commencing
with the financial year ending on 31 March 1992, the licensee shall provide to
the Director a statement complying with the provisions of paragraphs 3 and 4.

3. The statement to be provided to the Director under paragraph 2 shall:

     (a) be signed by 2 Directors of the licensee;

     (b) describe the arrangements made or to be made by the licensee to meet
     the generation security standard in each of the 7 succeeding financial
     years;

     (c) state the planning margin or margins adopted by the licensee for the
     purpose of the above arrangements and set out the methodology and
     calculations used in arriving at such margin or margins;

     (d) refer to data, assumptions and demand forecasts (including insofar as
     relevant those relating to diversity of demand, own generation,
     arrangements for trading energy and capacity with other persons,
     arrangements with relevant purchasers, including those permitting
     interruption and reduction of supply, forecast maximum demand from relevant
     purchasers, the maximum demand which the licensee could meet without
     failing to meet the generation security standard, contracted availability
     of generation, and load management (if any) of relevant purchasers); and

     (e) include such other matters as the Director shall specify in directions
     issued by the Director to the licensee for the purpose of this Condition
     not later than 6 months before the end of the financial year in which the
     statement is provided.


     4. The licensee shall upon request by the Director provide to the Director
     such information as the Director may require for the purpose of monitoring
     compliance with this Condition and to enable the Director (having regard to
     his statutory duties) 



                                       26
<PAGE>
 
to review the operation of the generation security standard.

5. The licensee shall not make or agree any alteration other than an alteration
to which paragraph 7 applies, to the arrangements described in any statement
provided to the Director under paragraph 2 as having been made by the licensee
to meet the generation security standard for the first financial year covered by
such statement.

6.   The licensee shall:-

     (a) procure that, except to the extent that the Director shall otherwise
     approve, arrangements described in any statement provided to the Director
     under paragraph 2 as failing to be made by the licensee, to meet the
     generation security standard for the first financial year covered by such
     statement shall be made; and

     (b) not make or agree any alteration, other than an alteration to which
     paragraph 7 applies, to the arrangements so made.

7. This paragraph applies to an alteration which the Director considers is
unlikely to result in the licensee failing to meet the generation security
standard.

8. The licensee shall not enter into any contract for the supply of electricity
if the entering into of the contract would cause demand from relevant purchasers
in the first year covered by the statement most recently provided to the
Director under paragraph 2 to exceed the maximum demand which the licensee can
meet in that year without failing to meet the generation security standard, as
referred to in such statement, unless the Director shall consider that the
entering into of the contract is unlikely to result in the licensee failing to
meet the generation security standard.

9. In the event that the Director, after consultation with the licensee, shall
at any time or from time to time issue a direction to the licensee for the
purpose of this Condition to the effect that, in the opinion of the Director, it
is desirable that the licensee make arrangements such as are specified in the
direction to meet the generation security standard, then the duty imposed by
paragraph 1 shall not be capable of being discharged by the licensee after such
date as shall be specified for the purpose in the direction except by the
licensee making the arrangements so specified.


                                       27

10. The duty of the licensee under paragraph 1 may, in relation to relevant
purchasers whose premises are located in isolated areas, be discharged by the
making of arrangements sufficient to meet a standard of generation security
(other than the generation security standard) agreed between the licensee and
the Director.

11. The provisions of this Condition are without prejudice to the duties of the
licensee under the Electricity Supply Regulations 1988.

12.  In this Condition:-

         "generation security standard"  means:-

                                         as will ensure:

                                        (i) that the supply of electricity to
                                        relevant purchasers will not be
                                        discontinued in more than 9 years in any
                                        period of 100 years; and

                                        (ii) that the voltage or frequency of
                                        electricity supplied to relevant
                                        purchasers will not be reduced below
                                        usual operational limits in more than 30
                                        years in any period of 100 years by
                                        reason of insufficiency of electricity
                                        generation available for the purposes of
                                        supply by the licensee to its relevant
                                        purchasers at times of annual system
                                        peak demand; and

                                        (b) sufficient electricity generation
                                        being available for the purposes of
                                        supply by the licensee to its relevant
                                        purchasers at times other than times of
                                        annual system peak demand to ensure that
                                        the standard of generation security at
                                        each such time will be not less than
                                        that referred to in sub-paragraph (a)
                                        above for times of annual system peak
                                        demand.

CONDITION 3. CONTROLLED MARKET START-UP
- ---------------------------------------

1. This Condition applies to those premises which the Licensee would during the
   franchise period be prohibited from supplying under the terms of Condition 2.

2. The Licensee shall not, after the expiry of the franchise period, supply
   electricity to any premises to which this Condition applies prior to such
   date as is specified in respect of such premises in a direction issued by the
   Director under this Condition.

3. A direction under this Condition may specify that different premises may be
   supplied from different dates, and for the purposes of this Condition
   premises may be specified by reference to:

   (a) their location;

   (b) whether or not they are Domestic Premises; or

   (c) the type of metering equipment installed at the premises,
       or any combination of these factors.

4.  Prior to making any direction under this Condition, the Director shall:

   (a) set out the proposed contents of the direction in a notice (the
       "proposals notice");

   (b) send the proposals notice to the Licensee, each Relevant Public
       Electricity Supplier in respect of premises specified in the notice, each
       consumers' committee appointed for an area within which the premises
       specified in the notice are situated and any other persons or bodies
       appearing to the Director to be representative of those likely to have an
       interest; and

   (c) consider any representations concerning the proposed contents of the
       direction which are made within a reasonable period, being not less than
       7 days from the date of issue of the proposals notice.

5.  Any direction issued by the Director under this Condition shall be in
    writing and shall be made not less than 28 days prior to the first date
    specified in the direction.

6.  Where, by virtue of this Condition, thc Licensee is prohibited from
    supplying any premises, the provisions of Condition 29 shall not apply in
    relation to the supply of electricity to those premises.

7.  When the Director has issued a direction under this Condition and it appears
    to him, having regard to the considerations set out in paragraph 8, that it
    would be unreasonable in all the circumstances for the direction to have
    effect on the dates specified therein in respect of any or all of those
    premises at which it has not yet had effect, then the Director may, subject
    to paragraph 9, withdraw or vary the direction
<PAGE>
 
   in respect of the premises to be supplied or of the dates from which they may
   be supplied, or both.

8. The considerations set out in this paragraph are:

   (a) whether the interests of customers in general, and in particular the
       interests of those occupying the premises specified in the direction,
       would be served by the withdrawal or variation of the direction;

   (b) whether the interests of any Electricity Supplier, including the
       Licensee, would be or would be likely to be unfairly prejudiced by the
       withdrawal or variation of the direction, or by a failure to do so;

   (c) the content of any representation made to the Director on the issue; and

   (d) such information as is available to the Director concerning:

        (i)   the manner in which arrangements for the supply of electricity to
              any premises to which this Condition applies have operated and are
              expected to operate;

        (ii)  the likely ability of the Licensee to fulfil its obligations under
              its Licence with respect to the supply of electricity to any of
              the premises concerned; and

        (iii) the likely ability of each Relevant Public Electricity Supplier to
              comply with the requirements of its public electricity supply
              licence in respect of the supply of electricity by the Licensee to
              the premises concerned.

9.  The Director shall not withdraw or vary a direction in respect of any
    premises when the date specified from which supply may commence is less than
    14 days from the date of the withdrawal or variation, unless the Director
    has the agreement of the Licensee, or failing that agreement the agreement
    of no fewer than two-thirds of the Second Tier Suppliers to whom a direction
    applies in respect of the same premises and dates.

10. When the Director withdraws or varies a direction in accordance with
    paragraph 7, he shall issue a notice of withdrawal or variation (as the case
    may be) and that notice shall have effect.

11. The Director shall publish any direction, or any notice of withdrawal or
    variation in such manner as in the opinion of the Director will secure
    adequate publicity for it.

12. A direction or a variation or withdrawal of a direction made under this
    Condition shall not distinguish between the Licensee and other Second Tier
    Suppliers except to the extent that the distinction is appropriate in all
    the circumstances given:

    (a) the information available to the Director in accordance with sub-
    paragraph 8(d)(ii); or
<PAGE>
 
  (b) where the Licensee is also a public electricity supplier, any failure by
      the Licensee to comply with the requirements of its public electricity
      supply licence, or with any agreement entered into in accordance with any
      such requirements, which adversely affects the ability of private
      electricity suppliers to supply electricity to any customers within its
      authorised area.

CONDITION 32. PROVISION OF SERVICES FOR PERSONS WHO ARE OF PENSIONABLE AGE OR
- -----------------------------------------------------------------------------
DISABLED OR CHRONICALLY SICK
- ----------------------------

1. The Licensee shall within two months of serving a Designated Supply Notice on
   the Director prepare and submit to the Director for his approval a code of
   practice detailing the special services the Licensee will make available for
   its Domestic Customers who are of pensionable age or disabled or chronically
   sick.

2. The code of practice shall include arrangements by which the Licensee will,
   where appropriate:

  (a) provide where practicable special controls and adaptors for electrical
      appliances and meters (including prepayment meters) and reposition meters
      (and shall set out any charges to be made for the provision of such
      services);

  (b) provide special means of identifying persons acting on behalf of the
      Licensee or the Relevant Public Electricity Supplier;

  (c) give advice on the use of electricity;

  (d) send bills in respect of the supply of electricity to a customer to any
      person who is willing to be sent such bills and is nominated by that
      customer (without prejudice, however, to the right of the Licensee to send
      such bills both to the customer and to the nominated person where that
      appears appropriate to the Licensee);

  (e) make available (free of charge) to blind and partially sighted customers,
      by telephone or other appropriate means, information concerning the
      details of any bill relating to the supply of electricity to them and a
      facility for enquiring or complaining in respect of any such bill or any
      service provided by the Licensee; and

  (f) make available (free of charge) to deaf and hearing impaired customers,
      being in possession of appropriate equipment, facilities to assist them in
      enquiring or complaining about any bill relating to the supply of
      electricity to them or any service provided by the Licensee.

(3)  The code of practice shall further include arrangements whereby the
     Licensee will:

  (a) take reasonable steps to draw the attention of customers to the existence
      of a register of customers who may be expected, by virtue of being of
      pensionable age or disabled or chronically sick, to require:
<PAGE>
 
     (i)  information and advice in respect of the matters set out at paragraph
          2; or

     (ii) advance notice of interruptions to the supply of electricity;

   (b) maintain such a register, comprising the relevant details of each
       customer who requests his inclusion on it; and

   (c) give to those customers so registered:

       (i) such information and advice in respect of the matters set out at
           paragraph 2 or in respect of interruptions to the supply of
           electricity as may be appropriate and is of such nature as shall be
           set out in the code of practice; and

      (ii) notice of the existence of another register maintained by the
           Relevant Public Electricity Supplier, in relation to such customers
           who may be expected to require advance notice of interruptions to the
           supply of electricity, on which such customers may be included.

4. The Licensee shall, with the consent or at the request of any customer
   included on the register maintained in accordance with sub-paragraph 3(b),
   provide the Relevant Public Electricity Supplier with appropriate details
   concerning such customer and his requirements for the purpose of his
   inclusion on the equivalent register maintained by the Relevant Public
   Electricity Supplier in accordance with the provisions of its public
   electricity supply licence.

5.  This Condition is subject to the provisions of Condition 37.

                (a)     that the New Party shall be admitted as a Party, in

                        provisions of Clause 3.4 shall apply.

                If the Executive Committee shall fail so to notify the New Party
                and the Director, the New Party may within 28 days after the
                expiry of the said 60 day period refer the matter to the

                of that Clause shall apply.

3.4     Additional Evidence: within 28 days (or such longer period as the
        Executive Committee in its absolute discretion may allow) after the

                written application and shall be to the effect set out in
                paragraph (a) or (b) of Clause 3.5.2, shall be final and binding

                his determination.

        3.5.2   (a)     If the determination is to the effect that the New Party
                        has fulfilled the said admission conditions, the New
                        Party shall be admitted and the provisions of Clause 3.6
                        shall apply.

                        no effect and the New Party shall not be, and shall not

                implementation, administration and development of the systems
                referred to in Clause 4.1.2 in a way which takes into account,
                and balances, the respective interests of actual and potential

        Transitional Arrangements

5.2     Transitional Arrangements: the Parties acknowledge and agree that the
        arrangements described or referred to in the first column of Schedule 12
        ("Transitional ------------ Arrangements") have been designed as
        transitional arrangements only. The Parties ------------ undertake with
        each other to use all reasonable endeavors (including, where
        appropriate, through their representation on the Executive Committee) to
        give effect to the principle (the "New Principle") set opposite the
        relevant Transitional ------------- Arrangement in the second column of
        Schedule 12 by the date set opposite such Transitional Arrangement in
        the third column of that Schedule. Clauses 5.9 to 5.14 (inclusive) shall
        have effect in relation to all Transitional Arrangements.

        Regular Reviews

5.3     Conduct of reviews: within a period (the "Review Period") of six months
        beginning on each of the dates referred to in Clause 5.5 (the "Review
        Dates") the Executive Committee shall review in consultation with the
        Settlement System Administrator and the Pool Auditor the operation in
        practice of this Agreement and the Settlement System to assess whether
        the principal objects and purpose set out in Clause 4.1 are being or
        could be better achieved. In carrying out each such review the Executive
        Committee shall give due consideration to any matter referred to it by
        any Party, the Pool Auditor, the Director or the Secretary of State.
        Clauses 5.4 to 5.15 (inclusive) shall have effect in relation to the
        reviews described in this Clause 5.3, and such reviews shall be in
        addition to the reviews associated with the Transitional Arrangements.

5.4     Initial Period reviews:

        5.4.1   in addition to the matters set out in Clause 5.3, as part of its
                review beginning on the date falling 24 months after the
                Effective Date the Effective Committee shall consider whether or
                not the Initial Period shall terminate with effect from the end
                of the then current Accounting Period in which the relevant
                Review Period ends taking into account the following:

                (a)     whether material changes to the nature or level of
                        service which the Settlement System Administrator is
                        required to provide under this Agreement in the
                        operation of the Settlement System have been proposed by
                        the Executive Committee or the Pool Members in general
                        meeting which have been accepted or are in the process
                        of being implemented or are under discussion and likely
                        to be accepted and implemented;


                                       37
<PAGE>
 
                (b)     whether anticipated costs to be incurred by the
                        Settlement System Administrator in running the
                        Settlement System are materially in excess of actual
                        costs for the immediately preceding Accounting Period
                        due, directly or indirectly, to circumstances beyond the
                        control of the Settlement System Administrator; and

                (c)     any other relevant considerations.

        5.4.2   The Executive Committee shall notify the Settlement System
                Administrator of the result of such considerations as are
                referred to the in Clause 5.4.1. In the absence of written
                representations to the contrary from the Settlement System
                Administrator to the Executive Committee to the effect that it
                is inequitable to conclude that the Initial Period should
                terminate (having regard to the consequences of such termination
                as set out in Schedule 4), such representations to be made
                within three months after the date of such notification, the
                Executive Committee may conclude that the Initial Period shall
                terminate, but may not otherwise come to such conclusion unless
                it has complied with Clause 5.4.3.

        5.4.3   Where written representations have been made by the Settlement
                System Administrator pursuant to Clause 5.4.2, the Executive
                Committee and the Settlement System Administrator shall
                negotiate in good faith with a view to agreeing whether the
                Initial Period should terminate. If the matter is not resolved
                by agreement between the Settlement System Administrator and the
                Executive Committee within one month (or such other period as
                the Settlement System Administrator and the Executive Committee
                may agree) after the Settlement System Administrator has made
                such written representations, the same shall be referred to
                arbitration in accordance with Clause 83. The costs of any such
                reference shall be borne in accordance with the Accounting
                Procedure.

        5.4.4   If for any reason the Executive Committee does not in the course
                of any review referred in Clause 5.3 reach the conclusion that
                the Initial Period should terminate or it is resolved pursuant
                to Clause 5.4.3 that the Initial Period should not terminate,
                the Executive Committee shall be obliged to have regard to the
                same considerations in each subsequent review to be carried out
                pursuant to Clause 5.3 and the provisions of Clauses 5.4.2 and
                5.4.3 shall apply in relation thereto.

        5.4.5   The Settlement System Administrator may, upon not less than two
                months' notice to the Executive Committee prior to any Review
                Date,


                                       38
<PAGE>
 
                determine that the Initial Period should terminate at the end of
                the then current Accounting Period whereupon the Initial Period
                shall so terminate.

5.5     Review Dates: the Review Dates are:

        5.5.1   those dates falling 12 and 24 months after the Effective Date;

        5.5.2   those dates falling on the last day of each successive period of
                two years, the first such period beginning on 30th March, 1992;
                and

        5.5.3   such other date(s) as the Pool Members in general meeting may
                from time to time determine.

5.6     Reports: promptly (and in any event within one month) after the end of
        each Review Period the Executive Committee shall prepare or cause to be
        prepared a written report of its review containing such matters as are
        referred to in Clause 5.7 and a copy of such report shall be sent to
        each Party, the Pool Auditor, the Director and the Secretary of State.
        If at the time of issue of such report no such conclusion or resolution
        as is referred to in Clause 5.4.2 or (as the case may be) 5.4.3 has been
        reached, the Executive Committee shall notify each Party, the Pool
        Auditor, the Director and the Secretary of State accordingly.

5.7     Content of reports: each report referred to in Clause 5.6 shall set out:

        5.7.1   the scope of the review conducted;

        5.7.2   the matters reviewed and the investigations and enquiries made;

        5.7.3   the findings of such review;

        5.7.4   the recommendations (if any) as to the changes to be made to
                this Agreement and the Settlement System so as to achieve or
                better to achieve the principal objects and purpose set out in
                Clause 4.1;

        5.7.5   the effect which any such recommendation referred to in Clause
                5.7.4 would, if implemented, have on the role of the Pool
                Auditor under this Agreement and any comments of the Pool
                Auditor thereon;

        5.7.6   the financial effects (if any) which any such recommendation
                referred to in Clause 5.7.4 would, if implemented, have on Pool
                Members;

        5.7.7   in the case of the report for the review beginning on the second
                Review Date and (if appropriate) each subsequent Review Date,
                whether the


                                       39
<PAGE>
 
                Executive Committee has concluded as set out in Clause 5.4.2,
                whether it has been resolved pursuant to Clause 5.4.3 that the
                Initial Period should terminate or (as the case may be) whether
                the Executive Committee has received notice under Clause 5.4.5;
                and

        5.7.8   such other matters as the Executive Committee shall consider
                appropriate.

        If any Committee Member shall disagree with any of the recommendations
        made in any such report, such report shall set out the reasons for such
        disagreement and any alternative proposals of such Committee Member.

5.8     General Meeting approval: within two months after the end of each Review
        Period the Executive Committee shall convene an extraordinary general
        meeting of Pool Members to consider and, if thought fit, approve (in
        whole or in part) the recommendations (the "Recommendations") made in
        the report referred to in Clause 5.6. If any Recommendation is so
        approved (an "Approved Recommendation") then, subject to Clause 13.5,
        the provisions of Clauses 5.9 to 5.14 (inclusive) shall have effect in
        relation thereto. If any Recommendation is not so approved, no further
        action shall be taken in respect thereof arising from such report.

        Works Programme

5.9     Works Programme: in respect of each Transitional Arrangement and each
        Approved Recommendation the Executive Committee shall:

        5.9.1   in the case of a Transitional Arrangement, b the date set
                opposite such Transitional Arrangement in the fourth column of
                Schedule 12; and

        5.9.2   in the case of an Approved Recommendation,by the date stipulated
                by the Pool Members in general meeting or (if no date is
                stipulated) within a reasonable time,

        prepare (or cause to be prepared) in consultation with the Pool Auditor
        a programme (the "Works Programme", which expression shall include any
        associated documentation hereinafter referred to in this Clause 5.9)
        which programme shall (unless otherwise resolved b the Executive
        Committee after consultation with those Parties not being Pool Members
        who might reasonably be expected to be affected by the Works Programme)
        include:

        (a)     a detailed timetable for the implementation of the New Principle
                or (as the case may be) the Approved Recommendation, including
                (where appropriate) a series of milestone and/or target dates
                for the achievement of specified parts of such programme;


                                       40
<PAGE>
 
        (b)     a full explanation of how such New Principle or approved
                Recommendation is to be implemented, including a detailed
                analysis of such New Principle or Approved Recommendation and
                the objectives which it is intended to achieve, the work
                involved, the resources required and the amendments likely to be
                required to this Agreement, the Specification and to any other
                relevant agreement or document and of any changes required to be
                made to the Software or the Hardware; and

        (c)     an estimate of the cost of such implementation supported by a
                breakdown of such costs and a detailed commentary on each
                element thereof together with proposals for the recovery of such
                cost,

        and (unless otherwise resolved by the Executive Committee after
        consultation with those Parties not being Pool Members who might
        reasonably be expected to be affected by the Works Programme) shall be
        supported by:

        (i)     any draft legal documentation required to give effect to the
                amendments referred to in paragraph (b) above; and

        (ii)    the outline form of agreement appointing the Project Manager as
                project manager for the implementation of the Works Programme
                (which form shall, where the Settlement System Administrator is
                or, in the Executive Committee's opinion, is likely to be the
                Project Manager or here the Works Programme involves changes to
                the Specification or the Software, be prepared in consultation
                with the Settlement System Administrator).

5.10    Review: the Executive Committee shall arrange for a copy of each Works
        Programme to be sent to each Party, the Pool Auditor and the Director
        for review under cover of a letter setting a deadline for receipt of
        comments on such Works Programme (being no earlier than one month and no
        later than two months after the date of despatch of copies of the Works
        Programme for comment) and indicating to whom such comments should be
        addressed. Within such time as is reasonable after the deadline set for
        receipt of comments, but, in any event, within two months thereafter,
        the Executive Committee shall revise (or cause to be revised) the Works
        Programme to take into account (so far as it considers desirable) the
        comments received from the Parties, the Pool Auditor and the Director.

5.11    General Meeting referral: as soon as a Works Programme has been revised
        as provided in Clause 5.10 (or, if the Executive Committee considers no
        such revision desirable, within one month after the deadline set under
        Clause 5.10 for receipt of comments on such Works Programme), the
        Executive Committee shall convene an extraordinary general meeting of
        Pool Members to consider and, if thought fit, approve such Work
        Programme (with or without amendment).


                                       41

5.12    Approval of the Works Programme:

        5.12.1  a Works Programme shall not be given effect to unless and until
                approved by the Pool Members in general meeting. Additionally,
                if a Works Programme or any part thereof shall involve a matter
                requiring the approval of Generators or Suppliers in separate
                general meeting under Clause 13.2 (a "Class Issue"), then such
                Works Programme shall not be given effect to unless and until
                approved by the relevant class of Pool Members. If a Works
                Programme shall not be duly approved (with or without
                amendment), then the Executive Committee shall revise (or cause
                to be revised) the same to take account of the wishes of the
                Pool Members in general meeting and/or (as the case may be) in
                separate general meeting and thereafter such revised Works
                Programme shall be re-submitted to the Pool Members in general
                meeting and, if such revised Works Programme or any part thereof
                shall involve a Class Issue, to the relevant Pool Members in
                separate general meeting, in each case for approval (with or
                without amendment). This revision and re-submission procedure
                shall be repeated as often as may be required until such time as
                the Pool Members in general meeting and, as necessary, in
                separate general meetings approve the Works Programme.

        5.12.2  Notwithstanding the provisions of Clause 5.12.1, the Executive
                Committee and each Party shall be entitled at any time prior to
                the approval of a Works Programme by the Pool Members in general
                meeting and (where required under Clause 5.12.1) by the relevant
                class of Pool Members in separate general meeting to apply to
                the Director requesting that the implementation of the New
                Principle or (as the case may be) the Approved Recommendation
                should not proceed or should not proceed in the manner set out
                by such Works Programme and, in such event, effect shall not be
                given to the Works Programme pending the determination of the
                Director and then (subject as provided in Clause 5.14) only to
                the extent (if at all) that the Director in his absolute
                discretion shall approve.

5.13    Implementation: the implementation of all Works Programmes shall be
        project managed by the Settlement System Administrator or (if the
        Settlement System Administrator is unable or unwilling so to project
        manage) such other person as the Executive Committee shall nominate (the
        "Project Manager") upon and subject to such terms and conditions as are
        agreed by the Executive Committee with the Project Manager and the cost
        thereof recovered in accordance with the terms of the relevant Works
        Programme. Cost overruns, liquidated damages and all other financing
        costs, incentives and penalties shall be financed, levied and/or paid at
        the times and in the manner provided for in such Works Programme. The
        Executive Committee shall


                                       42
<PAGE>
 
        require the Project Manager to prepare and submit to the Executive
        Committee no less frequently than quarterly a written report giving a
        detailed commentary on the progress of implementing each Work Programme,
        including a comparison of actual progress made against the timetable set
        by such Works Programme and of actual costs incurred against budgeted
        costs.

5.14    Pool Auditor's approval: at the completion of the work required by each
        Works Programme but prior to effect being given to the New Principle or
        (as the case may be) the Approved Recommendation the Executive Committee
        shall request the Pool Auditor to issue an opinion in form and content
        satisfactory to the Executive Committee confirming to all Parties and
        the Director that the Pool Auditor has inspected and tested the
        arrangements giving effect to the new Principle or (as the case may be)
        the Approved Recommendation and is satisfied (without qualification or
        reservation) that such arrangements do give effect to the New Principle
        or Approved Recommendation in the manner required by the Works
        Programme. The Executive Committee shall use all reasonable endeavors to
        make (or procure to be made) such modifications to such arrangements as
        are necessary to enable the Pool Auditor to give its opinion without
        qualification or reservation, and the costs of any such modification
        shall be recovered in accordance with the relevant Works Programme. If
        the Pool Auditor's opinion can be given only with qualification or
        reservation, the Executive Committee shall convene an extraordinary
        general meeting of Pool Members and, where required under Clause 5.12.1,
        a separate general meeting of Generators and/or (as the case may be)
        Suppliers to consider and, if thought fit, approve such arrangements in
        the knowledge that the Pool Auditor's opinion can be given only with
        qualification or reservation. Subject to the provisions of Clause 6,
        each of the Parties undertakes with each of the other Parties promptly
        following the issue of the Pool Auditor's opinion (but, where such
        opinion has a qualification or reservation, only after approval as
        aforesaid by the Pool Members in general meeting and, where required
        under Clause 5.12.1, by the relevant class of Pool Members in separate
        general meeting) to execute and deliver any amending agreement or other
        documents and to take such other action as may reasonably be required of
        it to give effect to such arrangements, in any such case at its own cost
        and expense.

5.15    Secretary of State's approval: in respect of the Secretary of State's
        decision as set out in his letter of 11th December, 1991 to the Chief
        Executive concerning the selling of the output of plant by Generators
        with on-site demand under this Agreement:

        5.15.1  each of the Parties undertakes with each of the other Parties
                forthwith to take all such steps (including as to the execution
                of any document) as may be required to give full force and
                effect to the decision of the Secretary of State. Each of the
                Parties shall take all such steps at its own costs and expense

                be entitled to recover any such costs and expenses in accordance
                with the terms of this Agreement; and

        5.15.2  each of the Parties acknowledges and agrees that damages would
                not be an adequate remedy for any failure by it to give in

                decision of the Secretary of State pursuant to this Clause 5.15
                and that, accordingly, each of the other Parties and the
                Director shall be entitled to the remedies of injunction,
                specific performance and other equitable relief for any
                threatened or actual such failure and that no proof of special
                damages shall be necessary for enforcement.

5.16    Director's modifications:

        5.16.1  Where the Monopolies and Mergers Commission has issued a report
                on a reference under section 12 of the Act which:

                (a)     includes conclusions to the effect that any of the
                        matters specified in the reference operate, or may be
                        expected to operate, against the public interest;

                (b)     specifies effects adverse to the public interest which
                        those matters have or may be expected to have;

                (c)     includes conclusions to the effect that those effects
                        could be remedied or prevented by modifications of the
                        conditions of any License and such modifications would
                        require a change to the Pooling and Settlement
                        Agreement; and

                (d)     specifies modifications by which those effects could be
                        remedied or prevented,

                the Director may, subject to the following provisions of this
                Clause, require such modifications to this Agreement as are
                requisite for the purpose of remedying or preventing the adverse
                effect specified in the report.

        5.16.2  Before requiring modifications to be made pursuant to this
                Clause, the Director shall have regard to the modifications
                specified in the report. Further, the Director shall not, and
                shall not be entitled to, require a modification to be made to
                this Agreement which modification could not have been achieved
                lawfully through a modification of one or more Licenses
                consequent upon the report (but as if, for this purpose, only


                                       44
<PAGE>
 
                those Parties who are holders of Licenses were parties to this
                Agreement).

        5.16.3  Before requiring modifications to be made pursuant to this
                Clause, the Director shall give notice:

                (a)     stating that he proposes to make the modifications and
                        setting out their effect;

                (b)     stating the reasons why he proposes to make the
                        modifications; and

                (c)     specifying the period (not being less than 28 days from
                        the date of publication of the notice) within which
                        representations or objections with respect to the
                        proposed modifications may be made,

                and shall consider any representations or objections from any
                person which are duly made and not withdrawn.

        5.16.4  A notice under Clause 5.16.3 shall be given:

                (a)     by publishing the notice in such manner as the Director
                        considers appropriate for the purpose of bringing the
                        matters to which the notice relates to the attention of
                        persons likely to be affected by the making o the
                        modifications; and

                (b)     by serving a copy of the notice on each Party, the
                        Executive Committee and the Pool Auditor.

        5.16.5  After considering any representations or objections which are
                duly made and not withdrawn pursuant to Clause 5.16.3, the
                Director may by notice published as provided in Clause 5.16.4(a)
                and served on those referred to in Clause 5.16.4(b) specify the
                modifications to this Agreement which he requires to be made and
                the date upon which such modifications are to take effect and
                each of the Parties undertakes with each other of the Parties
                promptly to take all such steps as may be necessary to give full
                force and effect to the modifications so required.

                of the relevant one(s) of them (in each case such consent not to

        Inconsistencies and Conflicts

6.8     Internal inconsistencies and conflicts: in the event of any
        inconsistency or conflict:


                                       49
<PAGE>
 
        6.8.1   the Pool Rules shall prevail over the other provisions of this
                Agreement (except Clause 4);

        6.8.2   the provisions of this Agreement shall prevail over the
                Specification; and

        6.8.3   the Specification shall prevail over the Software,

        and the Parties shall use all reasonable endeavors promptly to secure
        the elimination of such inconsistency or conflict.

6.9     External inconsistencies and conflicts:

        6.9.1   each of the Parties hereby acknowledges and agrees the
                desirability of achieving and maintaining consistency and
                absence of conflict between the provisions o this Agreement and
                the Grid Code but recognizes that, due principally to the
                different functions and objectives of this Agreement and the
                Grid Code, the fact that there may be Parties who are not bound
                by the Grid Code and the difference procedures in this Agreement
                and the Grid Code for review of their respective terms, it will
                not in all circumstances be possible to avoid inconsistency or
                conflict.

        6.9.2   Where at the Effective Date there is an inconsistency or
                conflict between the provisions of this Agreement and the Grid
                Code the Executive Committee shall first consider the matter and
                make recommendations and thereafter the Parties shall negotiate
                in good faith to eliminate such inconsistency and/or conflict
                having regard to the different functions and objectives o the
                Grid Code and this Agreement.

        6.9.3   Each of the Parties shall use its reasonable endeavors to ensure
                that where any change to this Agreement is proposed to be made
                which may reasonably be expected to require a change to the Grid
                Code (or vice versa) such change is brought by the Executive
                Committee to the attention of the Grid Code Review Panel in good
                time to enable it to consider what corresponding change, if any,
                should be made to the Grid Code or (as the case may be) this
                Agreement. In any such consideration, the Parties acknowledge
                and agree that it would be desirable in the event of any
                inconsistency or conflict between the provisions of this
                Agreement and the Grid Code if regard were had by the Grid Code
                Review Panel to the principles set out in Clause 6.9.4.

        6.9.4   The principles referred to in Clause 6.9.3 are that:


                                       50
<PAGE>
 
                (a)     where by reason of any inconsistency or conflict the
                        security, quality of supply and/or safe operation of the
                        NGC Transmission System under both normal and/or
                        abnormal operating conditions would necessarily be
                        compromised and/or the Grid Operator would necessarily
                        be in breach of its obligations under the Act or its
                        Transmission License, the provisions of this Agreement
                        should be made to conform (to the extent of such
                        inconsistency or conflict) to those of the Gird Code;

                meeting so convened shall not be held after the expiration of

        give notice of a meeting to, or the non-receipt of notice of a meeting
        by, any person entitled to receive notice shall not invalidate the
        proceedings at that meeting. In every such notice there shall appear
        with reasonable prominence a statement that a Pool Member entitled to
        attend and vote is entitled to appoint a proxy to attend, speak and
        (subject to Clause 12.1) vote in its place and that a proxy need not

                matter of interest which is the subject of this Agreement.

                general meeting is to take place.

        9.6.2   The provisions of Clauses 9.3 and 9.5 shall apply, mutatis
                mutandis, for the purposes of the notice and the calling of
                quarterly meetings pursuant to Clause 9.6.1 as if such meetings
                were general meetings of Pool Members and the provisions of
                Clause 10.9 shall also apply mutatis mutandis. Nothing in this
                Agreement shall prevent a quarterly meeting being convened also
                as an extraordinary general meeting.

                and binding. Pending any determination of the Director in
                respect of any such application, the relevant resolution (if
                passed) shall not have effect provided that, if the Director
                shall decline to accept a reference or to make a determination

                take effect from the date that the Director notifies the
                Executive Committee that he declines to accept the reference or
                to make the determination.

                either of the grounds referred to in Clause 13.5.1(i) or (ii)

                management); and

        27.2.2  a failure on the part of the Settlement System Administrator to
                receive all or a not insignificant part of its budgeted income
                in any Accounting Period, not being:-

                (a)     a failure which could have been avoided by proper and
                        efficient debt collection or could adequately be cured
                        by a provision for bad debts in the then current or next
                        succeeding Budget; or

                (b)     a failure which is remedied within a reasonable time
                        (and in any event within 120 days) after the Settlement
                        System Administrator has given the defaulting Pool
                        Member(s) and the

                        Executive Committee notice of such failure and requiring
                        the same to be remedied.

                For the avoidance of doubt, the Parties hereby acknowledge and
                agree that an application by the Settlement System Administrator
                to the Director to resign shall not, of itself, constitute good
                cause.

27.3    Removal: subject:-

        27.3.1  to good cause for the removal of the Settlement System
                Administrator having been demonstrated to the satisfaction of
                the Director; and

        27.3.2  as provided in Clauses 27.5 and 27.6.

        the Settlement System Administrator may at any time on or after the
        third anniversary of the Effective Date be removed as Settlement System
        Administrator by:-

                (a)     resolution of the Pool Members in general meeting passed
                        by Pool Members holding not less than 80 per cent. of
                        the Total Votes of Pool Members who are entitled to vote
                        in person or by proxy at a general meeting of Pool

                (b)     the giving by the Executive Committee to the Settlement
                        System Administrator after such resolution has been
                        passed or deemed effective (which the Executive
                        Committee shall promptly do) of not less than 6 months'
                        notice in writing of such removal (or such other period
                        as the Director may determine in response to the
                        application made to him for the purposes of Clause
                        27.3.1).

27.4    Good cause for removal: examples of good cause for the purposes of
        Clause 27.3.1 may include the following:-

        27.4.1  the failure by the Settlement System Administrator in any
                persistent, material respect or in any single, major respect to
                perform or comply with any of the obligations expressed to be
                assumed by it under this Agreement and such default (if capable
                of remedy) is not remedied within a reasonable period of time
                after the Executive Committee has given notice to the Settlement
                System Administrator of the occurrence thereof and requiring the
                same to be remedied;

        27.4.2  the revocation or determination or cessation in force for any
                reason whatsoever of the Condition of the Transmission Licence
                applicable to the Settlement System Administrator requiring the
                Settlement System

                Administrator to implement, maintain and operate a settlement
                system; and

        27.4.3  the Settlement System Administrator:-

                (a)     is unable to pay its debts (within the meaning of
                        section 123(1) or (2) of the Insolvency Act 1986, but
                        subject as hereinafter provided in this Clause 27.4.3)
                        or if any voluntary agreement is proposed in relation to
                        it under section 1 of that Act or enters into any scheme
                        of arrangement (other than for the purpose of
                        reconstruction or amalgamation upon terms and within
                        such period as may previously have been approved in
                        writing by the Executive Committee);

                (b)     has a receiver (which expression shall include an
                        administrative receiver within the meaning of section 29
                        of the Insolvency Act of 1986) of the whole or any
                        material part of its assets or undertaking appointed;

                (c)     has an administration order under section 8 of the
                        Insolvency Act of 1986 made in relation to it;

                (d)     passes any resolution for winding-up other than a
                        resolution previously approved in writing by the
                        Executive Committee; or

                (e)     becomes subject to an order by the High Court for
                        winding-up.

                For the purposes of paragraph (a) above section 123(1)(a) of the
                Insolvency Act of 1986 shall have effect as if for
                "(pound)250,000" and, further, the Settlement System
                Administrator shall not be deemed to be unable to pay its debts
                for the purposes of paragraph (a) above if any such demand as is
                mentioned in the said section is being contested in good faith
                by the Settlement System Administrator with recourse to all
                appropriate measures and procedures.

        For the avoidance of doubt, the Parties hereby acknowledge and agree
        that a resolution of Pool Members in general meeting to remove the
        Settlement Administrator shall not, of itself, constitute good cause.

27.5    Referral to the Director: the Parties agree that the Settlement System
        Administrator shall not be entitled to resign under Clause 27.1 and
        shall not be removed under Clause 27.3 unless the Director shall have
        notified the Settlement System Administrator and the Executive Committee
        (which shall promptly notify all the other


                                       111
<PAGE>
 
        Parties) that he is satisfied that good cause has been demonstrated for
        such resignation or removal.

27.6    Appointment of successor: any resignation by or removal of the
        Settlement System Administrator pursuant to Clause 27.1 or 27.3 shall
        not take effect until a successor Settlement System Administrator shall
        have been appointed and shall have accepted such appointment and the
        Settlement System Administrator shall continue to perform and discharge
        its duties and responsibilities under this Agreement until such
        appointment and acceptance. Subject as provided in Clause 27.7:-

        27.6.1  during the period of notice of resignation provided in Clause
                27.1 the Executive Committee shall have the right to appoint a
                successor but, if none is so appointed, the Settlement System
                Administrator shall have the right to appoint a successor; and

        27.6.2  upon removal of the Settlement System Administrator under Clause
                27.3 the Executive Committee shall have the right to appoint a
                successor.

27.7    Approval of the Director: the Parties undertake with each other that no
        successor Settlement System Administrator shall be appointed without the
        written approval of the Director first having been obtained.

27.8    Discharge: if a successor to the Settlement System Administrator is
        appointed under the provisions of Clause 27.6 and accepts such
        appointment, the retiring or removed Settlement System Administrator
        shall (save as provided in Clause 28 and save as regards any rights and
        liabilities accrued as at the date of retirement or removal) be
        discharged from any further obligation and shall have no further rights
        under this Agreement but shall remain entitled to the benefit of the
        provisions of Clauses 32 and 33 and any other provision of this
        Agreement providing for an indemnity in favour of the Settlement System
        Administrator, and its successor and (save as provided in this Clause
        27.8) each of the other Parties shall have the same rights and
        obligations amongst themselves as they would have had if such successor
        had been a party to this Agreement in place of the retiring or removed
        Settlement System Administrator.

28.     TRANSFER OF RESPONSIBILITIES AND ASSETS

28.1    Transfer of responsibilities and assets: upon a successor Settlement
        System Administrator being appointed under Clause 27.6 and accepting
        such appointment the retiring or removed Settlement System Administrator
        shall:-

        28.1.1  transfer to such successor all copies of all Software belonging
                to the Settlement System Administrator together with all rights

                of, any licence or other agreement to use and/or maintain the
                Software to such successor;

        28.1.3  when no longer reasonably required by the Settlement System
                Administrator to perform its duties and responsibilities under
                this Agreement, transfer to such successor all Hardware
                belonging to the Settlement System Administrator and required by
                such successor to carry out such successor's duties and
                responsibilities under this Agreement and necessary for the
                proper functioning of the Settlement System;

        28.1.4  make over to such successor all such records, manuals and data
                and other information in the ownership or under the control of
                the settlement System Administrator and relating to the
                operation, and necessary for the proper functioning, of the
                Settlement System, provided that, until such time as no longer
                reasonably required by the Settlement System Administrator for
                its operation hereunder of the Settlement System, the Settlement
                System Administrator may retain copies of all such records,
                manuals, data or other information solely for that purpose;

        28.1.5  provide such training and systems support as such successor may

                duties and responsibilities under this Agreement; and

        28.1.6  without prejudice to the foregoing provisions of this Clause 28,

                assets (excluding freehold and leasehold property), equipment,
                facilities, rights, know-how and transitional assistance which
                it possesses and which is necessary for such successor to have
                to operate the Settlement System in accordance with this
                Agreement and which is not otherwise readily obtainable by such
                successor,

        in each case on such reasonable terms (other than as to consideration)
        as may be agreed between the Settlement System Administrator, such
        successor and the Executive Committee (and, in default of agreement, the
        dispute shall be referred to arbitration in accordance with Clause 83)
        and in consideration of the payment of such sums as are referred to in
        Clause 28.2. The Settlement System Administrator further agrees, in
        consideration of the payment of such sums as are referred too in Clause
        28.2, to co-operate with any such successor and the Executive Committee
        so that the transfer of duties, responsibilities, assets and know-how to
        such successor is carried

        out causing as little disruption to the operation of the Settlement
        System and inconvenience to the Parties as is practicable in all the
        circumstances.

                        Executive Committee (and, in default of agreement, the
                        dispute shall be referred to arbitration in accordance

                        Administrator, if in giving notice pursuant to Clause
                        27.5 the Director shall state that in his opinion good
                        cause has been demonstrated on the basis of the grounds

                upon any communication or document reasonably believed by it to
                be genuine and correct and to have been communicated or signed
                by the person by whom it purports to be communicated or signed

        Notwithstanding the foregoing sentence, nothing in this Agreement shall
        prevent the Executive Committee from ratifying any act of the Settlement
        System Administrator.

31.6    Express authority: all directions and instructions of the Executive
        Committee or the Chief Executive to the Settlement System Administrator
        shall, as between the Settlement System Administrator and the Pool
        Members, be deemed to have the express authority of, and shall be
        binding without reservation upon, all Pool Members.

31.7    Authority of Pool Members: the Settlement System Administrator shall not
        be bound to act in accordance with the directions or instructions of the
        Pool Members unless the Pool Members act through the Executive
        Committee.

31.8    General Meetings: the Settlement System Administrator shall not be
        obliged to take any steps to ascertain whether any resolution of Pool
        Members in general meeting or of any class of Pool Members in separate
        general meeting which it is advised by the Executive Committee or the
        Chief Executive as having been passed was in fact passed or passed by
        the requisite majority and until the Settlement System Administrator
        shall have express written notice to the contrary from the Executive
        Committee or the Chief Executive it shall be entitled to assume that the
        relevant resolution was passed or (as the case may be) the relevant
        requisite majority was obtained.

31.9    Exceptions: notwithstanding the foregoing provisions of this Clause 31,
        in the performance of its duties and responsibilities under this
        Agreement the Settlement System Administrator shall not be bound to act
        in accordance with the directions or instructions of the Executive
        Committee or the Chief Executive if:-

        31.9.1  to do so would cause the Settlement System Administrator to
                breach any of its obligations under the Act or its Transmission
                Licence; or


                                       124
<PAGE>
 
        31.9.2  the Settlement System Administrator has reasonable grounds for
                believing that it would so breach any of such obligations and
                has consulted the Director and:-

                (a)     the Director has indicated that, notwithstanding any
                        such actual or potential breach, the Director would not
                        be minded to enforce compliance with those obligations
                        and the Settlement System Administrator has received an
                        indemnity reasonably satisfactory to it in respect of
                        its acting in accordance with such directions and
                        instructions.

        In any such event the Settlement System Administrator shall promptly
        notify the Executive Committee.

31.10   Reference to the Director: if at any time the Settlement System
        Administrator has a concern which is properly and reasonably found that,
        in acting in accordance with any direction or instruction of the
        Executive Committee or the Chief Executive, it will breach one or more
        of its obligations under the Act or its Transmission Licence, then, if
        having discussed the matter with the Executive Committee the matter
        remains unresolved, the Settlement System Administrator shall either
        comply with such direction or instruction or by notice in writing refer
        the same to the Director, such notice to set out in full the directions
        or instructions given to the Settlement System Administrator and the
        grounds for such concern and to be copied to the Executive Committee.
        Pending any guidance from the Director in response to any such reference
        and, provided that the Director shall not express any view that such
        reference is misconceived, vexatious or in respect of an improperly or
        unreasonably founded concern, the Settlement System Administrator shall
        not be liable to any of the other Parties for refusing to act in
        accordance with the relevant direction or instruction. If the Director
        shall express such a view, the Settlement system Administrator shall be
        so liable.

32.     STANDARD OF CARE AND LIMITATION OF LIABILITY

32.1    Standard of care: in the exercise of its duties and responsibilities
        under this Agreement the Settlement System Administrator shall exercise
        that degree of care, diligence, skill and judgement which would
        ordinarily be expected of a reasonably prudent operator of the
        Settlement System taking into account the circumstances actually known
        to the Settlement System Administrator, its officers and employees at
        the relevant time or which ought to have been known to it or them had it
        or they made such enquiries as were reasonable in the circumstances. In
        particular, but without prejudice to the generality of the foregoing, in
        the absence of directions and instructions given to it by the Executive
        Committee under this Agreement and having due regard to the constraints
        imposed on the Settlement System Administrator by the Accounting
        Procedure and the resources available to it, the Settlement System


                                       125
<PAGE>
 
        Administrator shall at all times conduct itself in a manner calculated

        nor any of its officers, employees or agents shall be liable to any of
        the other Parties for loss arising from any breach of this Agreement
        other than for loss directly resulting from such breach and which at the
        date of this Agreement was reasonably forseeable as not unlikely to
        occur in the ordinary course of events from such breach in respect of:-

        32.2.1  physical damage to the property of any of the other Parties or
                its or their respective officers, employees or agents; and/or

        32.2.2  the liability of any such other Party to any other person for
                loss in respect of physical damage to the property of any other
                person.

32.3    Death and personal injury: nothing in this Agreement shall exclude or
        limit the liability of the Settlement System Administrator for death or
        personal injury resulting from the negligence of the Settlement System
        Administrator or any of its officers, employees or agents and the
        Settlement System Administrator shall indemnify and keep indemnified
        each of the other Parties, its officers, employees or agents from and
        against all such and any loss or liability which any such other Party
        may suffer or incur by reason of any claim on account of death or
        personal injury resulting from the negligence of the Settlement System
        Administrator or any of its officers, employees or agents.

32.4    Exclusion of certain types of loss: subject to Clauses 32.3 and 39.7 and
        save where any provision of this Agreement provides for an indemnity,
        neither the Settlement System Administrator nor any of its officers,
        employees or agents shall in any circumstances whatsoever be liable to
        any of the other Parties for:-

        32.4.1  any loss of profit, loss of revenue, loss of use, loss of
                contract or loss of goodwill; or

        32.4.2  any indirect or consequential loss; or

        32.4.3  loss resulting from the liability of any other Party to any
                other person howsoever and whensoever arising save as provided
                in Clauses 32.2.2 and 32.3


                                       126

        holds the benefit of Clauses 32.2, 32.3 and 32.4 for itself and as
        trustee and agent for its officers, employees and agents.

32.6    Survival: each of Clauses 32.2, 32.3, 32.4 and 32.5 shall:-

        32.6.1  be construed as a separate and severable contract term, and if
                one or more of such Clauses is held to be invalid, unlawful or
                otherwise unenforceable the other or others of such Clauses
                shall remain in full force and effect and shall continue to bind
                the Parties; and

        32.6.2  survive termination of this Agreement.

32.7    Saving: for the avoidance of doubt, nothing in this Clause 32 shall
        prevent or restrict any Party enforcing any obligation (including suing
        for a debt) owed to it under or pursuant to this Agreement.

32.8    Full negotiation: each party acknowledges and agrees that the foregoing
        provisions of this Clause 32 have been the subject of discussion and
        negotiation and are fair and reasonable having regard to the
        circumstances as at the date of this Agreement.

                capacity as an Externally Interconnected Party in that
                Accounting period and (commencing with the Accounting period
                beginning in 1993) of the actual costs and expenses so incurred
                by it in the immediately preceding Accounting Period. If
                approved by the Executive Committee, all such costs and expenses
                shall be recovered by an Externally Interconnected Party from
                its Corresponding External Pool Members in accordance with

                Quarter Day relating thereto. Invoices shall be based on
                approved anticipated costs and expenses for the relevant
                Accounting Period and the first invoice for each Accounting
                Period (commencing with the Accounting Period beginning in 1993)
                shall include any correction that may be necessary on account on
                the approved actual costs and expenses being different from the
                approved anticipated costs and expenses for the immediately
                preceding Accounting Period.

                        Corresponding External Pool Member's due proportion
                        shall be the proportion which the sum of (i) the number
                        of its Generation Trading Blocks and (ii) one
                        (representing the notional Consumer referred to in
                        paragraph 26.5.2(d) of the Pool Rules) bears to the sum

39.2    Future developments (1): in respect of:


                                       135
<PAGE>
 
        39.2.1  each Works Programme involving a change to the Specification or
                the Software for which the Settlement System Administrator is
                appointed Project Manager or which is developed by or on behalf
                of the Settlement System Administrator; or

        39.2.2  all changes to the Software or the Specification (other than
                those referred to in Clause 39.2.1 or 39.3).

        the Settlement System Administrator shall ensure that, subject to Clause
        39.4, upon the implementation of such change the New Software which is
        the result of such change (excluding Settlement GOAL, GOALPOST, LOLP and
        Second Tier Software and any Software the development of which has been
        project managed by a person other than the Settlement System
        Administrator) is consistent in all material respects with, and will in
        its operation give effect in all material respects to, and the
        Operational Procedures are appropriate to give effect in all material
        respects to, the Specification relating to such New Software (other than
        those parts relating to Settlement GOAL, GOALPOST, LOLP and Second Tier
        Software and any Software the development of which has been project
        managed by a person other than the Settlement System Administrator.)

39.3    Future developments (2); in respect of each Works Programme or
        development specified in accordance with the Development Policies
        involving a change to the Specification or the Software for which the
        Settlement System Administrator is not appointed Project Manager and
        which is not developed by or on behalf of the Settlement System

        subject to Clause 39.5, upon the implementation of such change the New
        Software which is the result of such change (excluding Settlement GOAL,
        GOALPOST, LOLP and Second Tier Software and any Software the development
        of which has been project managed by a person other than the Settlement
        System Administrator) is consistent in all material respects with, and
        will in its operation give effect in all material respects to, and the
        Operational Procedures are appropriate to give effect in all material
        respects to, the Specification relating to such new Software (other than
        those parts relating to Settlement GOAL, GOALPOST, LOLP and Second Tier
        Software and any Software the development of which has been project
        managed by a person other than the Settlement System Administrator).

39.4    Relief from liability (1): the Settlement System Administrator shall be
        relieved from liability under Clause 39.2 if (but only to the extent
        that):-

        39.4.1  in good time (having regard to the time elapsed from the date
                upon which work on the relevant change is initiated by the
                Executive Committee to the date such change is implemented and
                taking into account, where appropriate, that testing of the New
                Software by or on behalf of the Settlement System Administrator
                may have taken place


                                       136
<PAGE>
 
                only after delivery thereof to the Settlement System
                Administrator) before such implementation the Settlement System
                Administrator has notified the Executive Committee in writing on
                Specified Grounds of inconsistencies between the New Software
                and/or its Operational Procedures and the Specification or
                operational failures in the Settlement System which will arise
                by reason of such implementation, which inconsistencies or
                operational failures remain unresolved at the time of such
                implementation; and

        39.4.2  any other such inconsistency could not reasonably have been
                expected to have been discovered by a project manager engaged to
                give effect to such change and acting in accordance with Good
                Industry Practice (taking into account the actual time given for
                such development and the testing of any relevant software).

39.5    Relieve from liability (2): the Settlement System Administrator shall be
        relived from liability under Clause 39.3 if (but only to the extent
        that):-

        39.5.1  in good time (having regard to the time elapsed from the date
                upon which work on the relevant change is initiated by the
                Executive Committee to the date such change is implemented and
                taking into account, where appropriate, that testing of the New
                Software by or on behalf of the Settlement System Administrator
                may have taken place only after delivery thereof to the
                Settlement System Administrator) before such change the
                Settlement system Administrator has notified the Executive
                Committee in writing on Specified Grounds of inconsistencies
                between the New Software and/or its Operational procedures and
                its Specification or operational failures in the Settlement
                System which will arise by reason of such implementation, which
                inconsistencies or operational failures remain unresolved at the
                time of such implementation; and

        39.5.2  any other such inconsistency could not reasonably have been
                expected to have been discovered by the Settlement System
                Administrator having regard to its actual knowledge of the
                detail of such change and the development works in relation
                thereto, its involvement generally in the development of the
                related Specification and the New Software and its actual
                knowledge of the Settlement System and the effect of such change
                thereon.

39.6    Specified Grounds: in this Clause 39 "Specified Grounds" means grounds
        reasonably held by the Settlement System Administrator for believing
        that at the time of the implementation of any such change as is referred
        to in Clause 39.2 or 39.3, there will be an inconsistency between the
        New Software (excluding Settlement GOAL,


                                       137
<PAGE>
 
        GOALPOST, LOLP and Second Tier Software and any Software the development
        of which has been project managed by a person other than the Settlement
        System Administrator) and/or its Operational procedures and its
        Specification (other than those parts relating to Settlement GOAL,
        GOALPOST, and Second Tier Software and any Software the development of
        which has been project managed by a person other than the Settlement
        System Administrator) or operational failures in the Settlement System
        which will arise by reason of such introduction or implementation, which
        grounds (and the reasons therefor) are fairly disclosed to the Executive
        Committee (taking into account the actual time given for the relevant
        development and the testing of any relevant software). In the event of
        any dispute between the Executive Committee and the Settlement System
        Administrator as to whether a matter has been fairly disclosed the same
        shall be referred promptly (and in any event within one month after the
        dispute has arisen) to arbitration in accordance with Clause 83. if the
        decision of the arbitrator(s) is that the matter has not been fairly
        disclosed, the relevant disclosure shall be ignored for the purpose of
        establishing a Specified Ground.

39.7    Liability for breach: the Settlement System Administrator's liability
        for breach of any of its obligations under the foregoing provisions of
        this Clause 39 shall be subject to the limitations set out in Clause 32
        save that the Settlement System Administrator shall also be liable to
        the extent (if any) agreed in writing with the Executive Committee in
        relation to each development relating to New Software (and shall not
        charge or recharge that liability to Pool Members).

39.8    Claims limitation: the Settlement System Administrator shall not be
        liable in respect of any breach of this Clause 39 unless:-

        (i)     a breach in respect of the New Software is notified to the
                Executive Committee or the Executive Committee becomes aware of
                such breach within 12 months after the date upon which such New
                Software is accepted by or on behalf of the Executive Committee;
                and

        (ii)    details of any claim to be made in respect of such breach are
                given to the Settlement System Administrator within 3 months
                after the Executive Committee is notified or otherwise becomes
                aware of such breach.

                Ancillary Services Provider of the Ancillary Services Business
                as Suppliers may from time to time reasonably require (having
                regard, in particular, to the disruptive effect of the same on

                such access to its Ancillary Services' operations and all
                records, documents, data and other information (other than

                the conduct of such operations in each case as the Pool Auditor
                may reasonably require and shall make available members of its
                staff to explain such operations and such other issues as the
                Pool Auditor considers relevant. The Pool Auditor shall not
                disclose and shall not be obliged to disclose to any Supplier
                details of prices paid to each Generator by the Ancillary
                Services Provider.

        51.5.2  The Suppliers shall not require more than two audits, tests,

        51.5.3  On instructing the Pool Auditor pursuant to Clause 51.5.1, the

                (b)     to make such recommendation as to changes in the
                        procedures, controls and/or audit coverage of the
                        Ancillary Services Business as the Pool Auditor
                        considers appropriate.

        51.5.4  The Ancillary Services Provider shall permit the Pool Auditor
                such access to its Ancillary Services' operations and all
                records, documents, data and other information (other than

                for the provision of Ancillary Services other than as stated in
                any Ancillary Services Agreement whether such discussions or
                negotiations take place before contracting or as part of any
                price review during the term of any Ancillary Services
                Agreement.

        51.5.5  The Pool Auditor shall report to the Suppliers and a copy of any
                report by the Pool Auditor relating to an audit, test, check or
                review pursuant to Clause 51.5.1 shall be provided to the
                Ancillary Services Provider. The Pool Auditor shall owe a duty
                of confidentiality to the Ancillary Services Provider save to
                the extent necessary to carryout the particular audit, test,
                check or review provided that any matter or thing set out in any
                report to the Suppliers shall not be subject to any such
                obligation and provided always that nothing in this Clause
                51.5.5 shall prevent the disclosure of any information pursuant
                to Clause 69. The Ancillary Services Provider shall be entitled
                to rely on any such report in any legal proceedings (including
                arbitration).

        51.5.6  if the Suppliers so resolve, the Ancillary Services provider
                shall promptly implement any recommendations made by the Pool

                recovered by the Ancillary Services Provider in accordance with
                the ASP Accounting Procedure.

51.6    Basis of Payment: the Ancillary Services Provider shall calculate the
        total amount payable under Ancillary Services Agreements in respect of
        each Settlement Day together with any amendments to calculations made
        for previous Settlement Days based upon information derived from the
        Grid Operator and the Settlement System Administrator. The charges to
        Suppliers for Ancillary Services shall comprise the costs so calculated
        together with the charges of the Ancillary Services provider calculated
        in accordance with Schedule 18. The Ancillary Services Provider shall
        notify a provisional sum to the Settlement System Administrator within
        three working days after receipt of such information from the Grid
        Operator and the Settlement System Administrator so as to be despatched
        by the Settlement System Administrator to Suppliers in accordance with
        the relevant Agreed Procedure to enable the Settlement System
        Administrator to apportion this sum to the sale of Active Energy
        according to the Pool Rules. The Ancillary Services Provider shall
        notify a final sum to the Settlement System Administrator by such time
        as will enable the Settlement System Administrator to take into account
        the final Settlement Run for each Settlement Day. Any unresolved amount
        shall be included in the final Settlement Run on an interim basis
        pending resolution. Thereafter it may be included (together with any
        errors or omissions subsequently arising) in any appropriate Settlement
        run.

51.7    Lost opportunity costs:

        51.7.1  subject to Clause 51.6, where the Ancillary Services Provider
                pays any Generator an amount in respect of lost opportunity
                costs the Ancillary Services Provider shall use reasonable
                endeavours to include any such amounts in its Ancillary Service
                charge to Suppliers in the Settlement Day on which it arises or
                as soon as possible thereafter.

        51.7.2  As soon as the Ancillary Services Provider is notified by any
                Generator that any obligation to pay lost opportunity costs may
                arise it shall consult the Suppliers and, without prejudice to
                the Ancillary Services Provider's right to recover such lost
                opportunity costs from Suppliers, if requested by the Suppliers
                shall recover such lost opportunity costs over such a period as
                may be agreed between the Ancillary Services Provider and the
                Suppliers and, in default of agreement, over such period as the
                Ancillary Services Provider considers to be reasonable.

51.8    Standard of Care: the standard of care applicable to the Ancillary
        Services Provider in the exercise of its duties and responsibilities
        pursuant to this Agreement shall be as set out in Clause 32.1 in respect
        of the Settlement System Administrator mutatis mutandis except that the
        final sentence in Clause 32.1 shall not apply.

        independent contractor in carrying out its duties pursuant to this
        Agreement and Clause 31.1 in respect of the Settlement System
        Administrator shall apply mutatis mutandis.

51.10   Miscellaneous: the provisions of Clauses 31.3.3, 31.3.4, 31.4, 31.5 and
        31.6 to 31.10 (inclusive) shall apply in respect of the Ancillary
        Services Provider mutatis mutandis.

51.11   Suppliers' Resolutions: where any matter is reserved under this Part XI
        or Schedule 18 for the Suppliers to resolve, that matter shall be
        decided upon by the majority vote of the Suppliers' representatives on
        the Executive Committee.

        (including effecting amendments to the Pool Rules) as may be necessary
        to give effect to UMIS. The Parties and the Executive Committee shall
        not refuse any such request on the grounds of any objections to any
        values specified in Annex 1 or the provisions of Annex 2 of Appendix 8
        to the Pool Rules as agreed from time to time between the suppliers and

                the difference between the Pool Selling Price and Pool Purchase
                Price (other than payments in respect of the Daily Pool Payment
                and/or the Genset Availability Payment) and to provide for
                payments and repayments associated therewith between the Grid

                Provider) and Consumers (as defined in the Pool Rules) i the
                form agreed pursuant to Clause 51A.3 as the same may be amended
                from time to time in accordance with the terms of that Clause.

        (ii)    whenever the agreement of the Suppliers is required it shall be
                given by a resolution of the Suppliers in a separate class
                meeting.

        provision, addition or amendment which is required to continue beyond
        that date to give effect to the operation of UMIS in respect of any

        elements comprising the difference between Pool Selling Price and Pool
        Purchase Price are managed or otherwise dealt with after 24.00 hours on
        31st March, 1995. This Clause 51A.7 may not be amended without the prior

        System Administrator, the Pool Funds Administrator and the Pool Auditor
        and, where appropriate, the Ancillary Services Provider, shall decide
        how such re-determination is to be effected, the re-allocation of moneys
        and the period of time over which any such reallocation is to take
        place, any such decision to take account and give effect, as nearly as
        practicable, to the principles and procedures set out in this Agreement

        Administrator to re-run, and the Settlement System Administrator shall
        re-run, Settlement in respect of any Settlement Day (or relevant part
        thereof) using the software and data originally used in respect of such
        Settlement Day (or relevant part thereof) but subject to such changes,
        amendments or additional inputs as may be required by the Executive
        Committee, the Ancillary Services Provider, such arbitrator(s) or court
        or (as the case may be) any other relevant Party. Any such re-run shall
        hereafter in this Clause 52 be referred to as a "Re-run".

52.2    Timing: the Settlement System Administrator shall arrange for any Re-run
        to be carried out as soon as is reasonably practicxable following
        request by the Executive Committee subject to the availability of
        computer time, compatible software, appropriate data and other
        resources.

52.3    Ancillary Services Provider: the Ancillary Services Provider shall have
        the right to incorporate any delayed or disputed amount in respect of
        the provision of Ancillary Services into Settlement without requiring a
        Re-run.

52.4    Notification: the Executive Committee shall promptly notify each Party,
        the Pool Auditor and the Director of each occasion on which it requries
        the Settlement System Administrator to carry out any Re-run, the reasons
        for such requirement, the


                                       164

        timing thereof and the period to be covered thereby and shall provide
        each Party with such information about any Re-run as is relevant to such
        Party and shall provide the Pool Auditor and the Director with full
        details of any Re-run.

52.5    Proviso: the foregoing provisions of this Clause 52 are subject to the
        proviso that no Re-run shall be carried out, and neither the Executive
        Committee nor any Party shall be entitled to requrie that a Re-run be
        carried out, in respect of a Settlement Day or any part thereof after
        the first anniversary of such Settlement Day, but so that this proviso
        shall not restrict the right of any Party to claim or recover any moneys
        properly due and owing to it under this Agreement.

55.     RIGHTS AND OBLIGATIONS OF POOL MEMBERS

55.1    Notification of unavailability: in respect of each Scheme Year for each
        Scheme Genset (other than the first) the Pool Member shall not later
        than 28 days before the start of that Scheme Year for each Scheme Genset

        member shall use all reasonable endeavours to ensure that the Scheme
        Planned Availability for each Scheme Year is the actual planned
        availability of such Scheme Genset.

56.     REVIEW

56.1    Review: within two months after the end of the third Scheme Year in
        respect of which the first Scheme Genset has been admitted to the Scheme

        shall (with the consent of the Director) appoint an independent firm of
        accountants of internationally recognised standing to review the Scheme
        to establish whether or not any element of the Scheme (or the Scheme
        taken as a whole) gives rise to a systematic imbalance which is likely
        to prevent the payments to the Scheme balancing payments from the Scheme
        and to submit to the Executive committee and the director a report
        setting out details of any such imbalance and his findings and
        recommendations for amending the Scheme designed to correct any such
        imbalance.

56.2    Amendments: the Executive Committee may make such amendments to the
        provisions of Section 27 of Schedule 9 as are required to implement the
        recommendations referred to in Clause 56.1. Any such amendments shall
        apply in respect of any Scheme Admission Application received after the
        date such amendments become effective and shall constitute a new Scheme.

56.3    Existing rights and obligations continue: any Pool Member shall remain
        entitled to the benefits and subject to the obligations of the Scheme
        with respect to any Scheme Genset in effect at the time of admission of
        that Scheme Genset to the Scheme.

        Instruction to the Pool Funds Administrator:-

        58.1.1  any Fuel Security Payment specified in that Payment Instruction
                (together with any Fuel Security Interest in relation thereto)
                shall be treated as an amount which is due to that Generator
                from those persons specified in that Payment Instruction and

60.7    Class rights:

        60.7.1  the levels of accuracy for Metering Equipment at points of
                connection of Second Tier Customers taking up to (and including)
                100kW of demand and at new points of connection between two or
                more Distribution Systems were not set as at 1st April, 1993 and
                shall be specified by the Executive Committee subject to the
                consent of any relevant class of Pool Members.

        60.7.2  Any change to the standards of accuracy of Metering Equipment
                required for Second Tier Customers up to (and including) 1MW
                before 31st March, 1994 or up to (and including) 100kW before
                31st March, 1998 shall be a change to the class rights of
                Suppliers.

60.8    Sealing: Metering Equipment shall be as secure as is practicable in all

                arrangements in relation to Metering Equipment.

60.9    Discrepancies between meter advance and half hourly value totals: the
        Parties acknowledge that, in transmitting metered data, impulses
        representing quantities of electricity may be lost between the relevant
        Meter and the Outstations giving rise to inaccuracies in half hourly
        values notwithstanding that the Metering Equipment is complying with the
        standards required by this Agreement. In such circumstances any
        differences between electricity flows recorded on meters and the total
        of the half hourly values recorded in the Settlement System will be
        noted at the time that the Meter is inspected and read by the Settlement
        System Administrator pursuant to paragraph 10 of Schedule 21 and will be
        dealt with as provided in the relevant Agreed Procedure. In any other
        circumstances where the Metering Equipment is not complying with the
        standards required by this Agreement such difference will be dealt with
        in accordance with paragraph 11 of Schedule 21.

60.10   Meter Failure:

        60.10.1 if at any time any Metering Equipment ceases to function or is
                found to be outside the prescribed limits of accuracy referred
                to in paragraph 7.3.1 of Schedule 21 for whatever reason then,
                except in those circumstances referred to in Clause 60.10.2:

                (a)     in the case of Metering Equipment ceasing to function,
                        during the period from the date of such cessation; or

                (b)     in any other case, during the period from the time when
                        such inaccuracy first occurred or, if such time is
                        unknown, from the midnight preceding the day during
                        which the disputed reading occurred.

                        until, in either such case, the date of adjustment,
                        replacement, repair or renewal of such Metering
                        Equipment under paragraph 8.4 of Schedule 21, the meter
                        readings shall be deemed to be those calculated pursuant
                        to the relevant Agreed Procedure.

        60.10.2 If at any time a voltage transformer fuse on a circuit supplying
                a Meter fails with the result that the Metering Equipment is
                outside the prescribed limits of accuracy referred to in
                paragraph 7.3.1 of Schedule 21, the meter readings from the time
                the failure is deemed to have


                                       181
<PAGE>
 
                occurred until the voltage transformer circuit is again restored
                to the Meter shall be deemed to be those calculated pursuant to
                the relevant Agreed Procedure. A failure shall be deemed to have
                occurred at the point in time provided for in the relevant
                Agreed Procedure.

                referred to in Clause 60.11.1) shall be referred to the
                Executive Committee. If any Party is not satisfied with the
                decision of the Executive Committee, the matter may be referred
                by such Party to arbitration in accordance with Clause 83.

        60.11.3 It is hereby expressly acknowledged and agreed by the Parties
                that the resolution of any dispute referred to in Clause 60.11.1
                or 60.11.2 shall in all cases be without prejudice to the
                bringing or pursuing of any claim, by or against, or the
                resolving of any issue between any one or more of such Parties
                or any other Party arising out of the same facts or
                circumstances, or facts or circumstances incidental to the facts
                and circumstances giving rise to such dispute, or upon the basis
                of which such dispute has been resolved, in favor of, or
                against, a Meter Operator Party or Meter Operator Parties.

        60.11.4 Upon the request of any Party which is a party to a dispute

                (iv)    the Distribution System of another Public Electricity
                        Supplier,

                        as the Settlement System Administrator may direct. The
                        appointment of each such Second Tier Agent shall
                        continue unless and until terminated by either such
                        Second Tier Agent or the Settlement System Administrator
                        giving to the other no less than 12 months' notice in
                        writing to expire on or after the fourth anniversary of
                        the date of this Agreement. The provisions of Clauses
                        60.16.1 to 60.16.20 and Clause 60.18 shall apply in
                        respect of such Second Tier Agents for so long as they
                        continue to be appointed as Second Tier Agents pursuant
                        to the provisions of Clause 60.16.1. For the avoidance
                        of doubt the provisions of Clause 60.16.15 shall
                        continue to apply to such Second Tier Agents after 31st
                        March 1994.

        60.16.2 Notwithstanding the provisions of Clause 60.16.1 the Settlement
                System Administrator may remove a Second Tier Agent at any time
                without notice if it fails in any persistent and material
                respect to perform its obligations hereunder, provided that the
                Settlement System Administrator shall have given written notice
                to the Second Tier Agent specifying in reasonable detail the
                nature of the breach and requiring the Second Tier Agent within
                28 days after notice of such breach (or within any longer period
                agreed between the Settlement System Administrator and the
                Second Tier Agent) and that at the expiry of such period the
                breach remains unremedied.

        60.16.3 A Second Tier Agent shall collect, aggregate, adjust and
                transmit metering data in accordance with the provisions of the
                relevant Agreed Procedure and the Pool Rules. The costs of any
                agency appointment made pursuant to this Part XV or Schedule 21
                shall be treated as Bought-In Supplies (as defined in Schedule
                4) and accordingly a cost beyond the control of the Settlement
                System Administrator.

        60.16.4 Each Second Tier Agent shall operate such agency business in an
                efficient and economic manner. It shall maintain such records,
                data and other information as the Pool Auditor may from time to
                time by notice and in reasonable detail to the Second Tier Agent
                reasonably require for the purposes of this Clause 60.16 or as
                may otherwise be reasonably necessary to enable the Settlement
                System Administrator to comply with its obligations under this
                Agreement which are referred to in Clause 60.16.1.

        60.16.5 The Settlement System Administrator may require the Pool Auditor
                to carry out audits, reviews, tests or checks in relation to
                each Second Tier Agent as the Settlement System Administrator
                may from time to time reasonably require (having regard, in
                particular, to the disruptive effect of the same on the business
                and operations of the Second Tier Agent). The terms of
                engagement of any such audit, reviews, tests or checks shall be
                made available to the Second Tier Agent. No more than two
                audits, reviews, tests or checks may be made in any one
                Accounting Period.

        60.16.6 In instructing the Pool Auditor pursuant to Clause 60.16.5 the
                Settlement System Administrator may require the Pool Auditor:

                (a)     forthwith to report any material concerns with respect
                        to matters the subject of the relevant audit, review,
                        tests or check; or

                (b)     make such recommendations as to changes in the
                        procedures, controls and/or audit coverage of the agency
                        business as the Pool Auditor considers appropriate.

        60.16.7 Any Second Tier Agent shall permit the Pool Auditor such access
                to its agency operations and all records, data and information
                held by the Second Tier Agent in the conduct of


                                       186
<PAGE>
 
                  such agency operations as the Pool Auditor may reasonably
                  require and shall make available members of its staff to
                  explain such operations and such other issues as the Pool
                  Auditor considers relevant.

         60.16.8  The Pool Auditor shall report to the Settlement System
                  Administrator and a copy of any report by the Pool Auditor
                  relating to any audit, review, tests or check made pursuant to
                  Clause 60.16.5 shall be provided to the Settlement System
                  Administrator. The Pool Auditor shall owe a duty of
                  confidentiality to the Second Tier Agent provided that nothing
                  in this Clause 60.16.8 shall prevent the disclosure of such
                  report to the Settlement System Administrator.

         60.16.9  If the Settlement System Administrator so requires, the Second
                  Tier Agent shall promptly implement any recommendation made by
                  the Pool Auditor in a report relating to any audit, review,
                  test or check pursuant to Clause 60.16.5 subject to a right of
                  appeal.

         60.16.10 The costs of any audit, test, review or check pursuant to
                  Clause 60.16.5 shall be borne by the Settlement System
                  Administrator which may recover the same through the
                  Accounting Procedure. The cost of implementing any
                  recommendations pursuant to Clause 60.16.9 may be recovered by
                  the Second Tier Agent through its agency charges.

         60.16.11 In the performance of its duties and obligations under this
                  Clause 60.16 a Second Tier Agent shall at all times be acting
                  as the agent of the Settlement System Administrator and the

                  Administrator's rights and obligations under this Agreement
                  may be required under the Second Tier Unmetered Supplies
                  Procedures or otherwise before this Clause 60.20 can become

         Party and wherever the dispute or difference or any part thereof arose
         the law of England shall be the proper law of any reference to

         defined in Clause 83.5) against any other Party (a "Contracting Party")
         which would but for this Clause 83.3 have been a dispute or difference
         referred to arbitration by virtue of Clause 83.1 then, notwithstanding
         the provisions of Clause 83.1 which shall not apply and in lieu of
         arbitration, the court in which the legal proceedings have been
         commenced shall hear and completely determine and adjudicate upon the
         legal proceedings and the Third Party Claim not only between the tariff
         customer and the Defendant Contracting Party but also between either or
         both of them and any other Contracting Party whether by way of third
         party proceedings (pursuant to the Rules of the Supreme Court 1965 or

         court

         Claim" shall mean:-

         83.5.1   any claim by a Defendant Contracting Party against a

                  proceedings) for any contribution or indemnity; or

         83.5.2   any claim by a Defendant Contracting Party against such a
                  Contracting Party for any relief or remedy relating to or
                  connected with the subject matter of the legal proceedings and
                  substantially the same as some relief or remedy claimed by the
                  tariff customer; or

         83.5.3   any requirement by a Defendant Contracting Party that any
                  question or issue relating to or connected with the subject
                  matter of the legal proceedings should be determined not only
                  as between the tariff customer and the defendant Contracting
                  Party but also as between either or both of them and a
                  Contracting Party (whether or not already a party to the legal
                  proceedings).

83.6     Limitation: Clause 83.3 shall apply only if at the time the legal
         proceedings are commenced no arbitration has been commenced between the
         Defendant Contracting Party and another Contracting Party raising or
         involving the same or substantially the same issues as would be raised
         by or involved in the Third Party Claim. The tribunal in any
         arbitration which has been commenced prior to the commencement of legal
         proceedings shall determine the question, in the event of dispute,
         whether the issues raised or involved are the same or substantially the
         same.

84.      JURISDICTION

84.1     Submission to jurisdiction: subject and without prejudice to Clauses 83
         and 84.4, all the Parties irrevocably agree that the courts of England
         are to have exclusive jurisdiction to settle any disputes which may
         arise out of or in connection with this Agreement and that accordingly
         any suit, action or proceeding (together in this Clause 84 referred to
         as "Proceedings") arising out of or in connection with this Agreement
         may be brought in such courts.

84.2     Waiver: each Party irrevocably waives any objection which it may have
         now or hereafter to the laying of the venue of any Proceedings in any
         such court as if referred to in this Clause and any claim that any such
         Proceedings have been brought in an inconvenient forum and further
         irrevocably agrees that a judgment in any Proceedings brought in the
         English courts shall be conclusive and binding upon such Party and may
         be enforced in the courts of any other jurisdiction.


                                       241
<PAGE>
 
84.3     Agent for service of process: each Party which is not incorporated in
         any part of England or Wales agrees that if it does not have, or shall
         cease to have, a place of business in England or Wales it will promptly
         and hereby does appoint the Settlement System Administrator (or such
         other person as shall be acceptable to the Executive Committee)
         irrevocably to accept service of process on its behalf in any
         Proceedings in England.

84.4     Arbitration: for the avoidance of doubt nothing contained in the
         foregoing provisions of this Clause 84 shall be taken as permitting a
         Party to commence Proceeding to be referred to arbitration.

85.      GOVERNING LAW

         This Agreement shall be governed by, and construed in all respects in
         accordance with, English law.

86.      THE SETTLEMENT SYSTEM ADMINISTRATOR'S CONTRACT

86.1     The Parties anticipate that this Agreement will be amended by a
         Supplemental Agreement to provide for revised terms and conditions upon
         and subject to which the Settlement System Administrator will
         administer and render services connected with the administration of the
         Settlement System (the "Revised Terms") and it is expected that these
         revised terms and conditions will be contained in a separate Schedule
         to (but nevertheless will form part of) this Agreement. At the date at
         which this Clause 86 takes effect negotiations are continuing on the
         Revised Terms.

86.2     Notwithstanding the fact that the Revised Terms do not exist at the
         date at which this Clause 86 takes effect, the Parties are keen to
         establish as soon as possible the terms of understanding reached
         between the Parties as to the revised terms and conditions to be
         contained in the Revised Terms. Accordingly, a letter of intent (the
         "Letter of Intent") is in the course of preparation which, and subject
         to the Executive Committee by unanimous resolution approving the Letter
         of Intent and the Settlement System Administrator acknowledging the
         same will revise in part the billing and financial reporting
         arrangements associated with the provision of services by the
         Settlement System Administrator described in Clause 86.1 from 1st
         April, 1994.

86.3     With a view to finalisation of the Revised Terms an agreement is also
         in the course of preparation which will give detailed effect to those
         revised terms and conditions (the "Framework Agreement") and subject to
         the Executive Committee first approving (with or without amendment) the
         Framework Agreement by unanimous resolution and the Settlement System
         Administrator executing and delivering the same, each of the Parties
         agrees that, it shall be bound by the Framework Agreement until the
         Framework End Date as if it were part of this Agreement provided that:-


                                       242
<PAGE>
 
         (i)      if the Framework Agreement shall expressly suspend provisions
                  of this Agreement which relate to the performance of services
                  by the Settlement System Administrator or other rights,
                  obligations, responsibilities and/or duties of the Settlement
                  System Administrator under this Agreement, those provisions
                  shall be suspended for the period ending no later than the
                  Framework End Date specified in the Framework Agreement;

         (ii)     subject as provided in (i) above, in the event of any
                  inconsistency or conflict between the provisions of the
                  Framework Agreement and this Agreement, the provisions of this
                  Agreement shall prevail; and

         (iii)    the expiry or termination of the Framework Agreement shall be
                  without prejudice to the accrued rights and liabilities of
                  each Party thereunder.

86.4     The Framework End Date shall be 31st March, 1995 or such other date,
         being no later than 31st March, 1996, as the Executive Committee and
         the Settlement System Administrator may agree,

IN WITNESS whereof this Agreement has been duly executed the day and year first
above written

                  confidentiality to the Settlement System Administrator except
                  to the extent necessary to conduct such Value For Money Audit
                  provided that nothing in this Section 2.2.2 shall prevent,
                  restrict or qualify the disclosure to Pool Members or the
                  Executive Committee in such report of such information as
                  ought reasonably to be disclosed.

         2.2.3    The Executive Committee shall not be entitled to require a
                  Value for Money Audit unless and until:-

                  (a)      the Executive Committee shall have given the
                           Settlement System Administrator at least one month's
                           notice of its intention to commission such Value For
                           Money Audit and the scope thereof; and

                  (b)      the Settlement System Administrator shall within that
                           period either:-

                           (i)      have failed to prepare and submit to the
                                    Executive Committee detailed proposals for
                                    the implementation of a cost-efficiency
                                    programme in respect of the Specified Area
                                    proposed to be the subject of such Value For
                                    Money Audit; or

                           (ii)     have submitted such detailed proposals or
                                    notified the Executive Committee that no
                                    such cost-efficiency programme is
                                    appropriate, and the Executive Committee
                                    shall have notified the Settlement System
                                    Administrator that it rejects such detailed
                                    proposals or (as the case may be) the
                                    Settlement System Administrator's
                                    notification that a cost-efficiency
                                    programme is not appropriate.

         2.2.4    No more than two Value For Money Audits shall be performed in
                  any Accounting Period. No more than one Value For Money Audit
                  shall be performed in respect of the same Specified Are in any
                  period of three consecutive Accounting Periods. A Value For
                  Money Audit may only be performed in respect of a Specified
                  Area and may not be performed on the Settlements Business on a
                  general basis or in respect of Bought-in Supplies.

                  such agreement or (as the case may be) the conclusions, if
                  any, set out in such report as soon as is reasonably
                  practicable following the date of such agreement or report.

                  Clause 83.

         the relevant auditor shall be entitled to require from the Settlement
         System Administrator's officers such information and explanations as
         are necessary for the performance of the Value For Money Audit (but,
         for the avoidance of doubt, the auditor shall not have access to any
         data used, information held or records kept in relation to any Pool
         Member without such Pool Member's prior written consent).

3.       AUDITORS' OPINION

         sent to the Executive Committee pursuant to Section 1.4 shall be

         (a)      the Statement of Costs is in agreement with the underlying
                  books and records of the Settlement System Administrator; and

                  The Settlement System Administrator's Charges

1.       GENERAL

         The Settlement System Administrator shall be entitled to recover from
         all Pool Members the charges set out in this Part C in respect of its
         operation of the Settlement System.

2.       THE INITIAL PERIOD

2.1      Initial Period - Annual Charges: in respect of each Accounting Period
         which begins during the Initial Period, the Settlement System
         Administrator shall be entitled to recover from Pool Members annual
         charges equal to the aggregate of the following amounts:-

         2.1.1    Total Operating Costs as identified by the Statement of Costs
                  of such period submitted pursuant to Section 1.4 of Part B;

         2.1.2    the Margin; and

         2.1.3    the Capital Charge.

2.2      Recovery of Charges: the due proportion (determined in accordance with
         Section 2.4) of the annual changes of the Settlement System
         Administrator referred to in Section 2.1 payable by each Pool Member
         for each Accounting Period in the Initial Period shall be recovered by
         monthly payments in advance from each Pool Member or, where the
         Settlement System Administrator and the Pool Member otherwise agree,
         semi-annually in advance (calculated on a best estimate and reasonable
         basis to be one twelfth or, as the case may be, one half of the annual
         charges payable by such Pool Member by reference to the most recent
         Statement of Costs). Except for the first month or, as the case may be,
         other period the Settlement System Administrator shall advise each Pool
         Member of such amount by invoice despatched to each Pool Member
         approximately 15 days prior to the first day of each month or other
         period. Such invoice shall be paid no later than the first day of such
         month or such other period. In the case of the first month or, as the
         case may be, other period, each Pool Member shall pay the amount
         advised in the relevant invoice within 15 days after the invoice date.
         Each Pool Member shall pay all amounts due hereunder in sterling in
         cleared funds in full without set off or counterclaim, withholding or
         deduction of any kind whatsoever but without prejudice to any other
         remedy. All charges are exclusive of United Kingdom Value Added Tax
         which shall be added to such charges, if applicable. In the event of
         any dispute regarding charges in any month, no Pool Member may withhold
         payment of any invoiced amount but may refer such dispute to
         arbitration in accordance with Clause 83 following payment.

2.3      Interest on non-payment: if any amount due to the Settlement System
         Administrator is not received on the due date the Pool Member required
         to pay such amount shall pay interest on the Settlement System
         Administrator on such amount from and including the date of default to
         the date of actual payment (as well after as before judgment) at the
         rate which is 4 per cent. per annum above the Base Rate from time to
         time during each period of default of National Westminster Bank PLC.

2.5      Amount of Charges: the amount of each such payment during the Initial
         Period shall be estimated initially by reference to the Budget and
         thereafter adjusted as required by this Part C. The Settlement System
         Administrator shall adjust the amount of each such payment by reference
         to the most recent Statement of Costs (whether quarterly or otherwise)
         and so as to take into account Total Operating Costs, the Margin
         thereon and the Capital Charge during the previous quarter and
         anticipated costs in respect of the same during the current quarter and
         shall recover from, or as appropriate, credit to each Pool Member its
         due proportion of the difference between actual and anticipated Total
         Operating Costs, the Margin thereon and the Capital Charge and payments
         received in respect of such costs, margin and charges in each case for
         the previous and the current quarter. Such recovery or credit shall
         take place by reference to an adjustment to each Pool Member's charges
         for the current quarter.

         Period which begins after the Initial Period, the Settlement System
         Administrator shall be entitled to recover the charges set out in
         Section 3.2.

3.2      Amount of Charges: the charges referred to in Section 3.1 shall be the
         aggregate of:-

         3.2.1    the Revenue Base and the Margin for the relevant Accounting
                  Period (as identified by the Statement of Costs for such
                  Accounting Period to be submitted pursuant to Section 1.4 of
                  Part B); and

         3.2.2    the Capital Charge for such Accounting Period.

         be recovered mutatis mutandis for Pool Members, in accordance with

3.4      Interest on non-payment: the provisions of Section 2.3 shall apply to
         any amount due to the Settlement System Administrator which is not
         received on the due date.

         (either up or down) its charges in any Accounting Period during the
         Post-Initial Period within one month following the publication of a

         3.5.1    the Revenue Base, the Margin and Capital Employed for the
                  immediately preceding Accounting Period; and

         3.5.2    the Settlement System Administrator's best estimate of its
                  charges for the current Accounting Period taking into account
                  the Cost Base for the immediately preceding Accounting Period.

         That part of the adjustment referred to in Section 3.5.1 shall be made
         only in respect of the charges applicable to persons who were Pool
         Members during the immediately preceding Accounting Period and shall
         take into account changes in Pool Membership during such preceding
         Accounting Period.

3.6      Sharing of Efficiency: the Settlement System Administrator shall be
         entitled to the benefit of all Efficiencies and, accordingly, to charge
         Pool Members the amount of all Efficiencies by including them in
         Budgets and Statements of Costs during the Post- Initial Period in the
         following manner. The amount of any Efficiency arising in any
         Accounting Period shall be identified in the Statement of Costs for
         such Accounting Period submitted pursuant to Section 1.4 of Part B and
         shall be taken into account in the Statement of Costs for the two
         successive Accounting Periods thereafter. Accordingly, the amount of
         any Efficiency may be included in any Statement of Costs for the two
         Accounting Periods following that in which the Efficiency is
         identified. In the Statement of Costs for the third consecutive
         Accounting Period and all following Accounting Periods thereafter the
         amount of such Efficiency shall be eliminated.

4.       CORPORATE OVERHEAD CHARGES AND PURCHASES

         take into account in any Budget or Statement of Costs (and consequently
         its charges to Pool Members) all corporate overhead charges payable by
         the Settlement System Administrator to its immediate holding company of
         any other affiliate which is solely a property holding company provided
         such corporate overhead charges are reasonable and in due proportion to
         the corporate overhead charges payable by other affiliates of the
         Settlement System Administrator or divisions of such affiliates as
         reported upon by the auditors of the Settlement System Administrator.

4.2      Goods of Services: purchases of goods or services from affiliates of

         System Administrator shall procure its auditors to confirm that such
         purchases have been contracted and paid for on an open market value
         basis.

         expenses and other amounts required by this Agreement (or any other
         agreement or document executed or prepared pursuant to this Agreement
         and for this purpose approved by the Executive Committee) to be dealt
         with "in accordance with the Accounting Period" shall be deemed to be a
         cost and expense of the operation of the Settlement System and shall be
         recovered by the Settlement System Administrator as part of Total
         Operating Costs or Revenue Base save that, where the same are treated
         as Revenue Base, they shall be regarded as costs beyond the control of
         the Settlement System Administrator which may recover the same in full
         from Pool Members who shall be obliged to pay the actual amount of such
         costs and expenses.

5.2      Fuel Security: except to the extent recoverable under any other
         provision of this Schedule, any additional costs necessarily incurred
         by the Settlement System Administrator in running the Settlements
         Business during a Security Period shall be regarded as beyond the
         control of the Settlement System Administrator, which may recover the
         same in full from Pool Members provided such costs have been verified
         as additional costs by the auditors of the Settlement System
         Administrator. Pool Members shall be obliged to pay the actual amount
         of such costs and expenses.

5.3      No Liability to finance: the Settlement System Administrator shall not
         be required to finance the Electricity Arbitration Association or the

                  Supplier), in accordance with the following formula:-

                  Suppliers' System Charge x NMS
                  ------------------------

                  where NMS is the total number of Non-Second Tier Systems in
                  that Supplier's authorized area as at the beginning of that
                  month;

                  Non-Second Tier Systems as at the beginning of each calendar
                  month shall be as notified to the Settlement System
                  Administrator (who shall then notify the Director) by the

                  later than 1st May, 1994 and the Settlement System
                  Administrator being entitled, in the absence of any
                  notification to the contrary, to rely on the last such
                  notification and other information in its possession) and, in

                  determined by the Director (whose determination shall be final
                  and binding); and

                  collection costs are incurred by Second Tier Agents or the
                  Settlement System Administrator shall be used in determining
                  the number of Second Tier Systems.

6.6      If in respect of any Specified Accounting Period (other than the one
         beginning on 1st April, 1997) the aggregate of all second tier system
         charges payable pursuant to Sections 6.5.1 and 6.5.2 and received by
         the Settlement System Administrator is less than or (as the case may
         be) more than the Total Second Tier System Charges for such Specified
         Accounting Period the deficit or (as the case may be) the surplus shall
         be carried forward to the immediately succeeding Specified Accounting
         Period and shall be included in the calculation of the Total Second
         Tier System Charges therefor, and in making any determination pursuant
         to Section 6.3 or 6.4 the Executive Committee shall use its reasonable
         endeavors to ensure that the aggregate of all second tier system
         charges payable pursuant to Sections 6.5.1 and 6.5.2 in respect of that
         immediately succeeding Specified Accounting Period will equal the
         anticipated Total Second Tier System Charges therefor. There shall be
         no carry forward of any such deficit or surplus arising in respect of
         the Specified Accounting Period beginning on 1st April, 1997.

7.       ALLOCATION OF CHARGES

7.1      Allocation: the Settlement System Administrator shall allocate its
         charges amongst Pool Member in accordance with Part D.

7.2      New and Former Pool Members: any Pool Member which is a Pool Member for
         part only of any Accounting Period shall pay charges on an interim
         basis of such amount as the Executive Committee estimates to be
         reasonable for such Accounting Period on the basis of the allocation of
         charges set out in Part D. Adjustments to charges on all Pool Members
         as a result of existing Pool Members leaving or new Pool Members
         joining will be made following, and shall be set out in, the Statement
         of Charges published for the relevant Accounting Period pursuant to
         Section 1.11 of Part B whereupon the Pool Members and/or former Pool
         Members shall be required to pay such additional amount or be entitled
         to such reimbursement as may be determined in accordance with this
         Agreement by an adjustment to charges in the then current Accounting
         Period.

8.       ADJUSTMENT TO MARGIN

         The Parties acknowledge and agree that the Margin has been determined
         by the Parties based upon:-

         8.1      the Net Margin of the Settlement Business falling within the
                  range 15 to 20 per cent.; and


                                       277
<PAGE>
 
         8.2      the Return on Capital Employed of the Settlements Business
                  falling within the range 15 to 20 per cent.; and

         8.3      the accounts of the Settlement System Administrator being
                  prepared on the basis of the Historic Cost Convention.

         For these purposes "Net Margin" means profit before interest and tax
         divided by turnover and "Return on Capital Employed" means profit
         before interest and tax divided by capital employed.

         In the event that either of the factors in Section 8.1 and 8.2 should
         fall outside its respective range or the factor in Section 8.3 should
         change, the Executive Committee and the Settlement System Administrator
         agree to meet to discuss the basis of the Margin and, if necessary, to
         agree in good faith a revised Margin based upon the requirements of the
         Settlements Business at such time. The Director shall be invited to
         attend any such meeting.

         During the Initial Period the Net Margin should not be taken into
         account in determining whether the Margin should be adjusted.

9.       CAPITAL EXPENDITURE

9.1      Capital Expenditure (1): the following provisions apply to Capital
         Expenditure by the Settlement System Administrator in respect of the
         Settlements Business:-

                  the Executive Committee, such approval to take into account an
                  appropriate sharing of the Efficiencies arising from such
                  Capital Expenditure;

         9.1.2    Capital Expenditure which may be recovered by Depreciation
                  charged to Pool Members specified in any Budget shall be

                  Executive Committee notifies the Settlement System
                  Administrator to the contrary within one month after receipt
                  of such Budget;

         9.1.3    in any Accounting Period the Settlement System Administrator
                  may incur Capital Expenditure which may be recovered by
                  Depreciation charged to Pool Members without the need to
                  consult or obtain the approval of the Executive Committee up

                  obtain the approval of the Executive Committee, in
                  circumstances where:-

                  (a)      the Settlement System Administrator would be in

                           Committee on such Capital Expenditure within a
                           reasonable period of time.

9.2      Capital Expenditure (2): Capital Expenditure not falling within Section
         9.1.1 to 9.1.4 may not be charged as Depreciation to Pool Members.

                  Pool Reserve Account and not subsequently withdrawn together
                  with a proportionate share of any interest from time to time

                  Administrator with confirmation from the issuing bank that the

                  required by this Schedule for an amount at least equal to the
                  required Security Amount applicable to it (less its balance on
                  the Pool Reserve Account) which Letter of Credit shall be
                  available for a period of not less than 12 months; or

         15.4.    procure such transfer to the Pool Funds Administration for
                  credit to the Pool Reserve Account as shall ensure that the
                  credit balance applicable to it standing to the credit of the
                  Pool Reserve Account shall be at lest equal to the required
                  Security Amount.

         provide Security Cover to the satisfaction of the Pool Funds
         Administrator in accordance with the provisions of this Section 15, the
         Pool Funds Administrator may at any time while such default continues,
         and if at such time any Letter of Credit forming part of the Security
         Cover is due to expire within nine Business Days it shall immediately,
         and without notice to such Supplier, demand payment of the entire
         amount of any outstanding Letter of Credit and shall credit the
         proceeds of the Letter of Credit to the Pool Reserve Account to be held
         on the terms and on the trusts set out in Section 5.

15.6     Substitute Letter of Credit: if the bank issuing any Suppler's Letter
         of Credit ceases to have the credit rating as is set out in sub-section
         1.1 under "Letter of Credit", such Supplier shall forthwith procure the
         issue of a substitute Letter of Credit by a bank that has such credit

                  applicable) shall be provided by Letter of Credit in an amount
                  to be assessed by the Executive Committee in consultation with
                  the Pool Funds Administrator as the aggregate amounts payable

<PAGE>
 
                  Security Cover may be provided in cash credited to the Pool
                  Reserve Account; and

         16.2.2   in respect of all Suppliers, the amounts required to be

                  Creditors.

         pursuant to this Part 3.

16.5     Increase or Decrease of Security Cover: if, after considering the
         recommendations of the Pool Funds Administrator and any representations
         which may be made by the relevant Supplier, the Executive Committee
         determines that a Supplier's Security cover should be increased or
         decreased, it shall so notify the Supplier, the Pool Funds
         Administrator and the Director. If the Executive Committee determines
         that such Security cover should be decreased, the Supplier consents and
         the Director so approve, that reduction shall take place. The Pool
         Funds Administrator shall consent to an appropriate reduction in the
         available amount of outstanding Letter of Credit and/or shall repay to
         the Supplier such part of the deposit held in the Pool Reserve Account
         for the account of such Supplier (together with all accrued interest on
         the part to be repaid) sufficient to reduce the Supplier's Security
         Amount to the level of Security Cover applicable to it. If the
         Executive Committee determines that the Supplier's Security Cover
         should be increased, the relevant Supplier shall, within five Business
         Days of notice as aforesaid, procure an additional or replacement
         Letter of Credit or transfer to the Pool Funds Administrator a cash

         of Security Cover applicable to it.

         the Pool Funds Administrator verifies the information provided by the
         Settlement System Administrator pursuant to sub-section 17.6 (any such
         Payment Date being the "Postponed Payment Date" and a reference to a
         Payment Date in this Schedules shall where applicable include a
         reference to a Postponed Payment Date). On the Postponed Payment Date,
         each Pool Member who took electricity on the Settlement Day to which
         the Postponed Payment Date applies shall pay interest on all such
         amounts for each day from and including the originally scheduled
         Payment Date to (but excluding) the Postponed Payment Date at such rate
         as shall be set from time to time by the Executive Committee or, in the
         absence of such rate, at the Reserve Interest Rate and all Pool Members
         who supplied electricity and the Ancillary Services Provider on such
         Settlement Day shall be entitled to receive in addition to the amounts
         that they are entitled to receive in respect of such supplies, interest
         on such amounts for each day during the same period and at the same
         rate. Interest shall accrue from day to day and shall be calculated by
         the Pool Funds Administrator on a 365 day year basis.

17.11    Further notification: where instructed by the Executive Committee, or
         where there is an award by a Court of competent jurisdiction or an
         arbitrator, or a decision of the Pool Auditor or where rendered
         appropriate by Clause 52, the Pool Funds Administrator shall issue
         further or other notification to the Pool Members and the Ancillary
         Services Provided in accordance with the provisions of this Section 17;
         and the Business Day which falls five Business Days after the date of
         such notification or earlier if practicable shall be a Payment Date.

17.12    Payment by Pool Debtor: without prejudice to its obligations in respect
         of supplies of electricity in accordance with the provisions of the
         Agreement, each Pool Debtor shall without defense, set-off or
         counterclaim (but without prejudice to any other rights or remedies
         available to such Pool Debtor) make payment on the relevant Payment
         Date of the full amount (including United Kingdom Value Added Tax) so
         notified as being payable by it for the account of those pool members
         and, as the case may be, the Ancillary Services Provider so notified as
         being entitled to receive payments. Payment shall be made in accordance
         with the terms of this Schedule. For the avoidance of doubt no payment
         made shall be treated as being paid on account or subject to any
         condition or reservation, notwithstanding the provisions for the making
         of subsequent adjusting payments provided in this Schedule. The

                                       839
<PAGE>
 
         provisions of sub-section 5.14 shall apply to any payment insofar as it
         is or may constitute an overpayment.

17.13    Liability several: save as otherwise expressly provided, the liability
         of each Pool Member for amounts payable by it pursuant to this Schedule
         is several and no Pool Member shall be liable for the default of any
         other Pool Member.

18.      ADVICE NOTES

18.1     Despatch of Advice Notes: not later than 17.00 hours on the relevant
         Notification Date (and, if this is not practicable, in good time (as
         that expression is explained in more detail in the relevant Agreed
         Procedure) to enable Pool Members and the Ancillary Services Provider
         to give all necessary instructions for payments to be effected on the
         relevant Payment Date) the Pool Funds Administrator shall:-

                  Advice Notes showing amounts (inclusive of United Kingdom

                  be paid by or to each Pool Member and the Ancillary Services
                  Provider on each Payment Date in respect of supplies of
                  electricity and the provision of Ancillary Services during
                  each Settlement Day to which that Notification Date relates;

         18.1.2   notify each Settlement Bank of amounts payable by the Pool
                  Members or the Ancillary Services Provider maintaining a
                  Settlement Account at the relevant Settlement Bank; and

         18.1.3   notify the Pool Banker of the amount to be remitted to the
                  Pool Clearing Account by each Settlement Bank.

18.2     Method of despatch: all Advice Notes shall be despatched by the means
         established in accordance with paragraphs 3.1.1 and 3.1.5, or by such
         other means as the Executive Committee may reasonably direct.

         indication if payment is being made under the provisions of paragraph
         17.9.1(b), 17.9.1(c) or 17.9.2.

18.4     Interest: where interest is payable by or to any Pool Member or the
         Ancillary Services Provider pursuant to this Schedule, the Pool Funds
         Administrator shall, at the same time as it despatches the Advice
         Notes, despatch to each Pool Member and the Ancillary Services Provider
         who is required to pay interest and to each Pool Member and the
         Ancillary Services Provider who is entitled to receive interest a
         statement showing the amount of interest payable or receivable by it,
         the rate of interest applicable thereto and the amount (if any) of tax
         to be withheld.

19.      PAYMENT PROCEDURE

19.1     Instructions for payment: each Pool Member and the Ancillary Services
         Provider shall, in respect of each Payment Date on which it is under an
         obligation to make a payment under this Schedule, make such
         arrangements as will ensure that such payment is credited to the
         relevant Collection Account in sufficient time to allow such Settlement
         Bank to make irrevocable arrangements to remit to the Pool Clearing
         Account by 12.30 hours the amount payable by that Pool Member or (as
         the case may be) the Ancillary Services Provider in respect of that
         Payment Date. Each Pool Member and the Ancillary Services Provider
         shall ensure all remittances by its bank to the relevant Collection
         Account shall be remittances for value on the relevant Payment Date.

19.2     Pool Funds Administrator's responsibilities:

         19.2.1   As soon as practicable and in any event not later than 13.00
                  hours on each Payment Date the Pool Funds Administrator shall
                  take such action as is required to ensure that all amounts
                  required to be credited to each Collection Account on such
                  Payment Date have been so credited (or if not so credited, the
                  reason therefor established).

         19.2.2   As soon as practicable and in any event not later than 13.30
                  hours on each Payment Date the Pool Funds Administrator shall
                  take such action as is required to ensure that all amounts
                  credited to each Collection Account on such Payment Date in
                  accordance with sub-section 19.1 have been remitted to the
                  Pool Clearing Account.

19.3     Non-payment by Pool Member: if a Pool Member becomes aware that a
         payment for which it is responsible will not be credited to the
         relevant Collection Account by 12.30 hours on the relevant Payment
         Date, it will immediately notify the Pool Funds Administrator, giving
         all details available to the Pool Member. The Pool Funds Administrator
         shall, as soon as it becomes aware that payment will not be remitted,
         use its best endeavours to establish the cause of non-payment.

19.4     Excess payments: if by 12.30 hours on any Payment Date the Pool Funds
         Administrator is advised by a Settlement Bank that the Settlement Bank
         will be making a payment in excess of the amount notified to the Pool
         Member pursuant to sub-section 18.1 in respect of that Payment Date, or
         if the Pool Banker notifies the Pool Funds Administrator by 13.30 hours
         that amounts greater than the amounts notified to the Pool Banker
         pursuant to paragraph 18.1.3 have been credited to the Pool Clearing
         Account, the Pool Funds Administrator shall use its best endeavours to
         ascertain the nature of the excess payment, to calculate the
         entitlement to such payment and to instruct the Pool Banker by 13.30
         hours that day to credit the appropriate Settlement Account(s) with the
         amount determined by the Pool Funds

                                       841
<PAGE>
 
         Administrator as falling due to each Pool Creditor in accordance with
         this Schedule provided that, where an External Pool Member makes a
         payment in excess of the amount owing by it on any Payment Date and the
         reason for such overpayment is the difficulty in remitting funds on a
         future Payment Date because of the mismatch of bank and public holidays
         between countries, the Pool Funds Administrator shall instruct the Pool
         Banker to credit the Pool Reserve Account with the amount of the
         excess. Any Pool Member who instructs its bank to make a payment in
         excess of the amount owing by that Pool Member on any Payment Date
         shall simultaneously with giving such instructions advise the Pool
         Funds Administrator in writing of the amount of the excess payment
         providing a description of what the Pool Member considers the excess
         payment relates to.

19.5     Payment to Pool Creditors: the Pool Funds Administrator shall, prior to
         14.30 hours on each day, calculate the amounts available for
         distribution to Pool Creditors on that day. As soon as practicable and
         not later than 14.30 hours on that day the Pool Funds Administrator
         shall give irrevocable instructions to the Pool Banker to remit from
         the Pool Clearing Account to the relevant Settlement Accounts
         maintained by the Pool Creditors the aggregate of amounts determined by
         the Pool Funds Administrator to be available for payment to Pool
         Creditors and, if required, to transfer amounts from the Pool Reserve
         Account or the Pool Borrowing Account to the Pool Clearing Account or
         vice versa.

19.6     Making good the Pool Reserve Account: if the Pool Reserve Account is
         debited or credited in or towards clearing the Pool Clearing Account,
         the Pool Funds Administrator shall as soon as possible thereafter take
         the necessary steps, including making any calculations or taking any
         action in accordance with Section 21, to reverse the debit or credit to
         the Pool Reverse Account and/or to make a call under a Letter of
         Credit.

19.7     Prohibition on transfers: the Pool Funds Administrator shall not at any
         time instruct the Pool Banker to transfer any sum from a Pool Account
         to another account (not being a Pool Account) unless that account is a
         Settlement Account.

19.8     Application of payments: where payments in respect of more than one
         Settlement Day are required to be settled on a Payment Date, payments
         in respect of the longest outstanding Settlement Day shall be, and be
         deemed to be, settled first.

19.9 Bank contacts: upon written request of the Pool Funds Administrator each
Pool Member and the Ancillary Services Provider shall provide the Pool Funds
Administrator in writing with the name of, and communication details for, one or
more individuals at the branch of its Settlement Bank from which payments or
payment instructions required to be made or given by it pursuant to this
Schedule originate (the "Local Branch") who is (are) familiar with the payment
procedures set out in this Section 19 applicable to such Pool Member or (as the
case may be) the Ancillary Services Provider, and shall promptly advise

                                       842
<PAGE>
 
the Pool Funds Administrator in writing of any change of any such individual or
his communication details. Each Pool Member and the Ancillary Services Provider
hereby authorizes the Pool Funds Administrator to contact any such individual to
enquire in respect of any Payment Date whether and in respect of what amount
instructions have been given for the remittance of any payment required to be
made by such Pool Member or (as the case may be) the Ancillary Services Provider
under this Schedule and/or whether such payment has been remitted or otherwise
made as provided for in this Schedule, and undertakes not to withdraw, qualify
or revoke such authority at any time. Each Pool Member and the Ancillary
Services Provider shall instruct its Local Branch to co-operate with the Pool
Funds Administrator accordingly and to provide the Pool Funds Administrator with
all such information as is necessary to answer such enquiries. The Pool Funds
Administrator shall comply with all reasonable security arrangements imposed by
the relevant Pool Member or the Ancillary Services Provider or any Local Branch.

20.      ALTERNATIVE PAYMENT PROCEDURE

20.1     Alternative Payment procedure: without prejudice to other obligations
         in the Agreement not substituted by the provisions of this Section 20,
         the provisions set out in this Section 20 shall apply:-

         20.1.1   if, on the Effective Date, it has not been possible to
                  establish the Notified Payments System (in which case they
                  shall continue to apply until the Notified Payments System is
                  established, or until such other time as the Executive
                  Committee may determine); or

         20.1.2   if, for any reason, it is not possible to apply the procedures
                  contemplated by the Notified Payments System and for so long
                  as it is not possible to apply such procedures.

20.2     Pool Debtor to effect remittance: each Pool Debtor shall, in respect of
         each Payment Date on which it is under an obligation to make a payment
         under the Agreement, give instructions to its bank, which it undertakes
         not to qualify, withdraw or revoke, to effect remittance to the Pool
         Clearing Account of the amount payable by that Pool Member to be
         received on that Payment Date.

20.3     Receipt of remittance: any remittance must be received by the Pool
         Banker in the Pool Clearing Account no later than 12.30 hours on the
         Payment Date unless arrangements have been made between the Pool Banker
         and the relevant Pool Member which shall be notified to the Pool Funds
         Administrator and which are satisfactory to the Pool Banker such that
         funds will be received for value on that Payment Date. The Pool Members
         shall ensure that instructions are given to their banks in sufficient
         time to ensure that their respective banks comply with this time limit.


                                       843
<PAGE>
 
20.4     Method of remittance: the Parties acknowledge and agree that when
         practicable to give effect to sub-section 20.3 a Pool Debtor shall
         cause remittances to be effected through CHAPS but, where not
         practicable or where the amount payable is less than the minimum
         individual amount then processed through CHAPS, the Pool Member shall
         ensure by whatever means at its disposal that remittance for value on
         the relevant Payment Date is made for credit to the Pool Clearing
         Account not later than 12.30 hours.

20.5     Notification of non-payment: the Parties acknowledge and agree that if
         a Pool Debtor becomes aware that a payment for which it is responsible
         will not be remitted to the Pool Banker by 12.30 hours on the relevant
         day, and where satisfactory arrangements, as referred to in sub-section
         20.3 have not been made, it shall immediately notify the Pool Funds
         Administrator, giving all details available to that Pool Debtor.

20.6     Payment default: if the Pool Funds Administrator determines at any time
         after 12.30 hours on any day that a remittance which should have been
         credited on that day to the Pool Clearing Account has not been made (or
         that the credit has not been received) (in whole or in part) and where
         satisfactory arrangements, as referred to in sub-section 20.3, have not
         been made, the provisions of Section 21 shall apply mutatis mutandis.

20.7     Late payment: if, after the Pool Funds Administrator shall, prior to
         14.30 hours on each day, calculate the amounts available for
         distribution to Pool Creditors on that day (including amounts resulting
         from the application of sub-section 20.6). Not later than 14.30 hours
         on that day the Pool Funds Administrator shall give instructions to the
         Pool Banker, which it undertakes not to qualify, withdraw or revoke, to
         make same day value remittances to the Pool Creditors.

20.9     Construction: where the provisions of this Section 20 apply references
         in Sections 5 and 18 and sub-section 21.1 to "Settlement Bank" and
         "Collection Account" shall be construed as references to "bank" and
         "Pool Clearing Account" respectively.

21.      PAYMENT DEFAULT

21.1     Payment default: subject as provided by sub-section 21.12, if, by 12.30
         hours on a Payment Date, the Pool Funds Administrator has been notified
         by a Settlement Bank or it otherwise has reason to believe that a
         Settlement Bank will not remit to the Pool Clearing Account all or any
         part (the "amount in default") of any amount which has been notified by
         the Pool Funds Administrator as being payable by a Pool Debtor (the
         "non-paying Pool Debtor") on the relevant Payment Date in sufficient
         time to ensure that such amount can be cleared through the Pool
         Clearing Account not later than the close of banking business on such
         Payment Date, the Pool Funds Administrator shall act in accordance with
         the following provisions (or whichever of

                                       844
<PAGE>
 
         them shall apply) in the order in which they appear until the Pool
         Funds Administrator is satisfied that the Pool Clearing Account will
         clear not later than the close of business on the relevant Payment
         Date:-

         21.1.1   if the Pool Funds Administrator has been able to identify the
                  non-paying Pool Debtor in sufficient time to apply this
                  paragraph 21.1.1 and to the extent that the non-payment Pool
                  Debtor is entitled to receive payment from any Pool Debtor
                  pursuant to this Schedule on the relevant Payment Date, then
                  the Pool Funds Administrator shall (unless it reasonably
                  believes that such set-off shall be unlawful) set off the
                  amount of such entitlement against the amount in default;

         21.1.2   if the Pool Funds Administrator has been able to identify the
                  non-paying Pool Debtor in sufficient time to apply this
                  paragraph 21.1.2, the Pool Funds Administrator shall debit the
                  Pool Reserve Account and credit the Pool Clearing Account with
                  a sum not exceeding the amount of funds standing to the credit
                  of the non-paying Pool Debtor in the Pool Reserve Account;

         21.1.3   subject to sub-section 21.2, the Pool Funds Administrator
                  shall debit the Pool Reserve Account and credit the Pool
                  Clearing Account with a sum not exceeding the amount of funds
                  then standing to the credit of the Poll Reserve Account to the
                  extent that they represent Security Cover provided in
                  accordance with paragraph 15.1.2, the transfer of such amount
                  as is not attributable to the funds standing to the credit of
                  the non-paying Pool Debtor by each Supplier rateably according
                  to its share of the funds standing to the credit of the Pool
                  Reserve Account to the extent that they represent Security
                  Cover provided in accordance with paragraph 15.1.2, at the
                  time immediately prior to the transfer, such loans to be
                  repayable on demand and to carry interest at the Reserve
                  Interest Rate and in any case repayable not later than two
                  Business Days after they arise after which, to the extent that
                  any such loans remain outstanding, such loans shall carry
                  interest at the Default Interest Rate (which interest shall be
                  credited to the relevant Supplier's Pool Ledger Account). Each
                  Supplier hereby irrevocably authorizes the Pool Funds
                  Administrator to advance, collect in and enforce payment of
                  such loans for its account and on its behalf and each Pool
                  Member hereby irrevocably consents to the making of such loans
                  to the extent that such Pool Member has a share in the Pool
                  Reserve Account;

         21.1.4   if the Pool Funds Administrator has been able to identify the
                  non-paying Pool Debtor in sufficient time to apply this
                  paragraph 21.1.4 and provided that the Pool Funds
                  Administrator is satisfied that the proceeds of a call under
                  the Letter of Credit will be paid into the Pool Clearing
                  Account in

                                       845
<PAGE>
 
                  sufficient time to ensure that it will clear not later than
                  the close of business on the relevant Payment Date, the Pool
                  Funds Administrator shall make a call under the Letter of
                  Credit supplied by the non-paying Pool Debtor in a sum not
                  exceeding the available amount of all such Letter of Credit,
                  and the Pool Funds Administrator shall cause the proceeds of
                  such call or calls to be paid into the Pool Clearing Account;

         21.1.5   subject to sub-section 21.2 and provided that the Pool Funds
                  Administrator is satisfied that the proceeds of a call under a
                  Letter of Credit will be paid into the Pool Clearing Account
                  in sufficient time to ensure that it will clear not later than
                  the close of business on the relevant Payment Date, the Pool
                  Funds Administrator shall make a call under one or more
                  Letters of Credit supplied by Pool Members (other than the
                  non-paying Pool Debtor) in a total sum not exceeding the total
                  available amount of all such Letters of Credit to the extent
                  that such amount represents Security Cover provided in
                  accordance with paragraph 15.1.2, and the Pool Funds
                  Administrator shall cause the proceeds of such call or calls
                  to be paid into the Pool Clearing Account. The transfer of
                  such proceeds into the Pool Clearing Account shall be deemed
                  to give rise to a series of loans to the non-paying Pool
                  Debtor by each Supplier whose Letter of Credit was called
                  rateably according to the amounts called udder their
                  respective Letter of Credit, such loans to be repayable on
                  demand and to carry interest at the Reserve Interest Rate and
                  in any case repayable not later than two Business Days after
                  they arise after which, to the extent that any such loans
                  remain outstanding, such loans shall carry interest at the
                  Default Interest Rate (which interest shall be credited to the
                  relevant Supplier's Pool Ledger Account). Each Supplier hereby
                  irrevocably authorizes the Pool Funds Administrator to
                  advance, collect in and enforce payment of such loans for its
                  account and on its behalf and each Pool Member hereby
                  irrevocably consents to the making of such loans to the extent
                  that such Pool Member has a share in the Pool Reserve Account;

         21.1.6   if and to the extent that, notwithstanding application of the
                  foregoing measures, it is not possible to clear the Pool
                  Clearing Account by any of the foregoing means, the Pool Funds
                  Administrator shall reduce payments to all Pool Creditors in
                  proportion to the amounts payable to them on the relevant
                  Payment Date by an aggregate amount equal to the amount
                  necessary to clear the Pool Clearing Account and shall account
                  for such reduction in the Pool Ledger Accounts as amounts due
                  and owing by the non-paying Pool Debtor to each Pool Creditor
                  whose payments were reduced.

21.2     Amounts in default likely to be remedied: the Pool Funds Administrator
         shall not apply paragraph 21.1.3 or 21.1.5 unless it considers in good
         faith that the amount in

                                       846
<PAGE>
 
         default is likely to be remedied by the non-paying Pool Debtor no later
         than the next Business Day and in such a case the Pool Funds
         Administrator shall only apply paragraphs 21.1.2 and 21.1.4 to the
         extent of any amounts provided by way of Security Cover pursuant to
         paragraph 15.1.2.

21.3     Loans part of Pool Reserve Assets: any loans arising pursuant to
         paragraph 21.1.3 or 21.1.5 shall be deemed to constitute part of the
         Pool Reserve Assets and all repayments of such loans, together with
         interest thereon, shall be paid into the Pool Reserve Account for the
         account of each Supplier who is deemed to have made such loan.

21.4     Repayment of loans: if any loans to a non-paying Pool Debtor arising
         pursuant to paragraph 21.1.3 or 21.1.5 shall not have been repaid in
         full (together with interest at the rate or rates specified therein) by
         12.00 hours on the next Business Day after such loan is deemed to have
         arisen, the Pool Funds Administrator shall make a call under the Letter
         of Credit (if any) which shall been supplied by the non-paying Pool
         Debtor and which remains outstanding in an amount not exceeding the
         amount necessary to repay such loans and all accrued interest in full
         and, if the proceeds of any Letter of Credit are insufficient to repay
         all outstanding loans to the relevant non-paying Pool Debtor, such
         proceeds shall be applied towards repayment of each such outstanding
         loan rateably.

21.5     Reduction of payments to Pool Creditors: if, after the date that any
         loans to a non- paying Pool Debtor arise pursuant to paragraph 21.1.3
         or 21.1.5, the Pool Funds Administrator shall reasonably be of the
         opinion that the non-paying Pool Debtor will not repay forthwith all of
         such loans and all accrued interest in full or the loans have not been
         repaid with all interest within two Business Days after they arose
         (whichever occurs first), the Pool Funds Administrator shall reduce
         payments to all Pool Creditors in proportion to the amounts payable to
         them on the Payment Date to which the default relates and any
         succeeding Payment Dates as may be required by an aggregate amount
         necessary to restore the balance in the Pool Reserve Account to the sum
         for the time being required under this Schedule to be deposited by the
         Pool Members other than the non-paying Pool Debtor, to the intent that
         all loans arising under paragraphs 21.1.3 and 21.1.5 and remaining
         undischarged after application of the non-paying Pool Debtor's Letter
         of Credit are discharged in full together with interest thereon at the
         Reserve Interest Rate.

21.6     Obligation to make calls: if and whenever the Pool Funds Administrator
         has not applied the provisions of paragraph 21.1.4, and has reduced
         payments to Pool Creditors in accordance with paragraph 21.1.6, it
         shall, on the relevant Payment Date or so soon thereafter as the
         non-paying Pool Debtor has been identified (but, in any event, not
         later than the close of business on the Business Day following such
         Payment Date) make a call under the Letter of Credit supplied by the
         non-paying Pool Debtor in a sum sufficient to cover the reduction made
         under paragraph 21.1.6

                                       847
<PAGE>
 
         (but not exceeding the available amount of all such Letters of Credit)
         and the Pool Funds Administrator shall cause the proceeds of such call
         to be paid forthwith into the Pool Reserve Account. On the next
         Business Day following receipt of such proceeds, the Pool Funds
         Administrator shall pay such amounts as have been credited to the Pool
         Reserve Account to the Pool Creditors whose payments were reduced in
         full or (as the case may be) in proportion to their respective
         entitlement including interest on such amounts at the Reserve Interest
         Rate.

21.7     Indemnification by non-paying Pool Debtor: the non-paying Pool Debtor
         shall indemnify and keep indemnified each Pool Member whose Letter of
         Credit is called under paragraph 21.1.5 and/or who is deemed to have
         made loans under paragraph 21.1.3 or 21.1.5 on demand against all
         costs, expenses and losses (including the costs of management time)
         suffered or incurred by such Pool Member arising from its Letter of
         Credit being so called (including the costs of reinstating the same) or
         such loans being deemed to have been made to the extent that such Pool
         Member is not compensated under this Section 21. This indemnity shall
         be in addition to or without prejudice to the liability of the
         non-paying Pool Debtor to repay the loan, together with accrued
         interest, which arises pursuant to paragraph 21.1.5. The Pool
         Creditors, in proportion to the amounts payable to them on the Payment
         Date to which a default relates in respect of which the Pool Funds
         Administrator has operated sub-section 21.5, and any succeeding Payment
         Dates as may be required, shall indemnify and keep indemnified each
         Pool Member as is referred to in the earlier provisions of this
         sub-section 21.7 to the extent of any failure by the non- paying Pool
         Debtor to fulfill its obligations under this sub-section 21.7.

21.8     Notification of Pool Creditors: the Pool Funds Administrator shall use
         all reasonable endeavours promptly to notify the relevant Pool
         Creditors whenever it makes any such reduction as is referred to in
         paragraph 21.1.6.

21.9     Default Interest: save as otherwise provided in the Agreement
         (including where an express rate of interest is provided), if any
         amount payable by any Pool Debtor pursuant to this Schedule is not
         given value for the due date by close of banking business on the due
         date the Pool Debtor shall on written demand by the Pool Funds
         Administrator pay to the Pool Funds Administrator, for the account of
         the person or persons entitled to receive the amount in default,
         interest on such amount from the due date up to the day of actual
         receipt by the Pool Funds Administrator (as well after as before
         judgment) at the Default Interest Rate.

21.10    Application of payments: any amount received by the Pool Funds
         Administrator from a non-paying Pool Debtor for the credit of any Pool
         Account shall be applied by the Pool Funds Administrator in or towards
         payment of amounts payable by the non-paying Pool Debtor to Pool
         Creditors on each successive Payment Date in respect of which there is
         an outstanding default (with the longest outstanding default being
         settled first).

21.11    Clearing of Pool Clearing Account: all amounts standing to the credit
         of the Pool Clearing Account at the close of business on any Payment
         Date shall be transferred to the Pool Reserve Account so that the
         balance in the Pool Clearing Account shall at the end of such day be
         nil.

21.12    Credit Facility: if and for so long as the Credit Facility remains
         unconditionally available, the provision of this Section 21 shall apply
         with the modifications provided by Section 25.

23.      PAYMENT ERRORS

23.1     Overpayments: if for any reason whatsoever (including the negligence of
         the Pool Banker or the Pool Funds Administrator) a Pool Creditor
         receives on any Payment Date a payment in excess of the amount
         disclosed in the Pool Ledger Account as calculated as being payable to
         it (an "overpayment" (including but not limited to the proceeds of any
         loan made or deemed to be made in accordance with Section 21 or Section
         25 to any non-paying Pool Debtor which becomes insolvent before such
         advance is repaid) the provisions of sub-section 5.15 apply, and the
         Pool Creditor shall forthwith notify the Pool Funds Administrator of
         the amount of the overpayment and shall forthwith pay the overpayment
         into a Pool Account specified by the Pool Funds Administrator.

23.2     Repayment of overpayment (1): if prior to a Pool Creditor notifying the
         Pool Funds Administrator of the overpayment, the Pool Funds
         Administrator receives notice (from the Pool Banker or otherwise) of
         the overpayment, the Pool Funds Administrator shall forthwith require
         (by written notice) that the recipient of the overpayment pay the
         overpayment to a Pool Account specified by the Pool Funds Administrator
         and any Pool Creditor who receives such notice shall forthwith pay the
         amount to an account specified by the Pool Funds Administrator. If the
         overpayment is repaid within two Business Days of receiving the notice,
         the overpayment (or any part not paid) shall bear interest at the
         Reserve Interest Rate of at such rate as shall be set from time to time
         by the Executive Committee from the date the overpayment was received
         up to the date that value is given in a Pool Account by the Pool Funds
         Administrator (as well after as before judgment). Any overpayment (or
         part thereof) not repaid within two Business Days after demand therefor
         in accordance with this Section 23 shall bear interest at the Default
         Interest Rate from the expiry of that period and shall be recoverable
         in accordance with Section 24. The Pool Funds Administrator shall
         account to those entitled to payment by reason of an overpayment.

23.3     Repayment of overpayment (2): upon receipt of the overpayment
         (including any interest) the Pool Funds Administrator shall (forthwith
         upon entitlement to it being ascertained) pay the amount received to
         the Pool Member or the Ancillary Services Provider who should have
         received the payment on the Payment Date.

23.4     Underpayments: if for any reason whatsoever (including the negligence
         of the Pool Banker or the Pool Funds Administrator) a Pool Creditor
         does not receive on the relevant Payment Date the full amount disclosed
         as owing to it pursuant to the Pool Ledger Account (an "underpayment")
         that Pool Creditor shall forthwith notify the Pool Funds Administrator
         of the amount of the underpayment, and the Pool Funds Administrator
         after consultation with the Pool Banker shall use all reasonable
         endeavours to identify such person as shall have received any
         corresponding overpayment and promptly to correct the underpayment. If,
         by reason of

                                       851
<PAGE>
 
         negligence, the Pool Funds Administrator holds or has under its control
         amounts which it ought properly to have paid to Pool Members, such Pool
         Members shall be entitled to interest on such amounts at the Default
         Interest Rate and for such period as the Pool Funds Administrator
         improperly holds or has such amounts under its control.

24.      ENFORCEMENT OF CLAIMS

24.1     Notification of amount in default: without prejudice to the provisions
         of Section 21, if a Pool Member shall fail to pay any amount payable
         pursuant to this Schedule on the due date, the Pool Funds Administrator
         shall notify the Director, the Executive Committee and each Pool
         Creditor to whom the amount in default is owed pursuant to this
         Agreement of the name of the non-paying Pool Debtor, the aggregate
         amount in default and the amount owed to each Pool Creditor.

24.2     Duties of Pool Funds Administrator: except as otherwise expressly
         provided in this Schedule, the Pool Funds Administrator shall not be
         required to ascertain or enquire as to the performance or observance by
         any Pool Member or the Ancillary Services Provider of its obligations
         under the Agreement and shall have no duty to inform the Executive
         Committee or any Pool Member or the Ancillary Services Provider of any
         default, other than a failure to pay as may come to its attention.

24.3     Notice before action: each Pool Creditor shall give notice to the Pool
         Funds Administrator before instituting any action or proceedings in any
         court to enforce payments due to it pursuant to this Schedule. Upon
         receipt of any notice under this sub-section 24.3, the Pool Funds
         Administrator will as soon as practicable notify the Executive
         Committee, all Pool Members, the Settlement System Administrator, the
         Ancillary Services Provider and the Director.

24.4     Proceedings to Recover Overdue Amounts: without prejudice to the right
         of any Pool Member to bring such proceedings as it sees fit in
         connection with matters related to the Agreement, the Pool Funds
         Administrator shall, if instructed to do so by the Executive Committee,
         bring proceedings against a Pool Member (on behalf of those Pool
         Members who have indicated their willingness to the Executive Committee
         for the Pool Funds Administrator first so to act) for the recovery of
         any amounts due by that Pool Member pursuant to this Schedule so long
         as the Pool Funds Administrator has first reached agreement with the
         Executive Committee and the Pool Members as to appropriate
         remuneration, is indemnified to its reasonable satisfaction or, if it
         so requires, provided that it shall have received such security as it
         may reasonably request against all costs, claims, expenses (including
         legal fees) and liabilities which it will or may sustain or incur in
         complying with such instructions. Save as provided in the foregoing
         provisions of this sub-section 24.4, the Pool Funds Administrator shall
         not be obliged to bring any such proceedings.

25.      CREDIT FACILITY: PAYMENT DEFAULTS

25.1     Purpose of Credit Facility: It is acknowledged that the Credit Facility
         provides an alternative to the Security Cover referred to in paragraph
         15.1.2 and the Pool Funds Administrator will use the Credit Facility to
         cover banking error and payment error and to minimize reductions of
         payments to Pool Creditors unless it consider in good faith that an
         amount in default is not likely to be remedied by the non-paying Pool
         Debtor no later than the next Business Day.

25.2     Modification of other provisions of this Schedule: if and so long as
         the Credit Facility is unconditionally available to the Pool Funds
         Administrator (whether or not there remains any amount undrawn),
         paragraphs 15.1.2, 21.1.3 and 21.1.5 shall be of no effect and the
         remaining provisions of this Schedule shall be implemented on the basis
         that the following sub-sections apply.

25.3     Payment default: the Pool Funds Administrator shall operate the Credit
         Facility on the following basis:-

         25.3.1   the Credit Facility may be drawn down by the Pool Funds
                  Administrator if, by 12.30 hours on any Payment Date, there is
                  an amount in default unless the Pool funds Administrator
                  considers in good faith that the amount in default is not
                  likely to be remedied by the non-paying Pool Debtor no later
                  than the next Business Day;

         25.3.2   if paragraph 25.3.1 applies such that the Credit Facility may
                  be drawn down, the Pool Funds Administrator will first act in
                  accordance with paragraph 21.1.1, will then draw on the Credit
                  Facility for an amount not exceeding the available amount
                  under the Credit Facility (after allowing for any repayment to
                  be made to the Facility Bank under sub-section 25.6) and, if
                  it is not possible to clear the Pool Clearing Account by
                  either or both of those means, it will then act in accordance
                  with paragraph 21.1.6;

         25.3.3   if paragraph 25.3.1 does not apply, then the Pool funds
                  Administrator will act in accordance first with paragraph
                  21.1.1, then with paragraph 21.1.2, then with paragraph 21.1.4
                  and only then with paragraph 21.1.6.

25.4     Amounts in default: each non-paying Pool Debtor will be responsible in
         relation to any amount in default in accordance with the following
         paragraphs:-

                  repayment of all amounts of principal drawn down under the
                  Credit Facility in respect of any amount in default relating
                  to that Pool Debtor as if the Pool Funds Administrator had
                  made a loan to such Pool Debtor of the relevant amount and the
                  amounts so payable are to be paid to, or otherwise made
                  available

                  for credit to, the Pool Clearing Account as soon as possible,
                  but in any event no later than two Business Days after the
                  relevant Payment Date;

         25.4.2   each non-paying Pool Debtor will be responsible also for
                  interest (determined in accordance with paragraph 25.4.4) on
                  all amounts of principal drawn down under the Credit Facility
                  in respect of any amount in default relating to that Pool
                  Debtor as if the Pool Funds Administrator had made a loan to
                  such Pool Debtor of the relevant amount and the amount so
                  payable by way of interest is to be paid to, or otherwise made
                  available for credit to, the Pool Clearing Account by no later
                  than the day notified by the Pool Funds Administrator to such
                  Pool Debtor for payment thereof (being the date which is 2
                  Business Days prior to the date on which interest is payable
                  under the Credit Facility by the Pool Funds Administrator to
                  the Facility Bank for the month in which the principal amount
                  in question was outstanding);

         25.4.3   each non-paying Pool Debtor will further be responsible for
                  its proportionate share (determined in accordance with
                  paragraph 25.4.5) of any additional sum payable to the
                  Facility Bank pursuant to the terms of the Credit Facility as
                  if the Pool Funds Administrator had made a loan to such Pool
                  Debtor of the relevant amount and the amount so payable is to
                  be paid to, or otherwise made available for credit to, the
                  Pool Clearing Account forthwith on notification thereof by the
                  Pool Funds Administrator to the Pool Debtor in question;

         25.4.4   for the purposes of paragraph 25.4.2, interest is to be
                  calculated using the effective daily rate of interest
                  reasonably determined by the Pool Funds Administrator on the
                  basis of the aggregate interest (including any compound
                  interest) payable under the Credit Facility in relation to any
                  particular day;

         25.4.5   for the purposes of paragraph 25.4.3, the proportionate share
                  for a particular non-paying Pool Debtor is the amount (if any)
                  which the Pool Funds Administrator reasonably determines
                  (after consultation with the Facility Bank) as being the
                  amount of any additional sum payable in accordance with the
                  terms of the Credit Facility attributable to drawings under
                  the Credit Facility made in respect of that Pool Debtor.

25.5     Application of payments: on the Relevant Date the Pool Funds
         Administrator shall, if the amount in question has not been received in
         full from the non-paying Pool Debtor:-


                                       854
<PAGE>
 
         25.5.1   first debit the Pool Reserve Account and credit the Pool
                  Clearing Account with a sum not exceeding the amount of funds
                  (if any) standing to the credit of the non-paying Pool Debtor
                  in the Pool Reserve Account;

         25.5.2   if that sum is insufficient to repay in full the amount in
                  question, the Pool Funds Administrator shall call the Letter
                  of Credit (if any) provided by the non-paying Pool Debtor (for
                  an amount not exceeding the available amount) and pay or cause
                  the proceeds thereof to be paid into the Pool Clearing
                  Account; and

         25.5.3   if the amount credited to the Pool Clearing Account after
                  following the foregoing procedure is insufficient, reduce
                  payments to all Pool Creditors in proportion to the amounts
                  payable to them on the Payment Date to which the default
                  relates,

         so that, in any case, the Pool Funds Administrator has available to it
         on the Pool Clearing Account sufficient funds to comply with paragraph
         25.6. For the purposes of this paragraph, the "Relevant Date" is
         whichever of the following is applicable:-

         (a)      in relation to any principal amount for which a non-paying
                  Pool Debtor is responsible under paragraph 25.4.1, the last
                  date specified for payment under paragraph 25.4.1;

         (b)      in relation to any principal amount as referred to in
                  sub-paragraph (a), the first date (if earlier than the date
                  referred to in sub-paragraph (a)) on which the Pool Funds
                  Administrator is reasonably of the opinion that the non-paying
                  Pool Debtor will not repay forthwith all of the amounts of
                  principal in question;

         (c)      in relation to payment of interest under paragraph 25.4.2, the
                  last date for payment thereof; and

         (d)      in relation to an additional amount under paragraph 25.4.3 the
                  last date for payment of this amount.

25.6     Payments to Facility Bank: to the extent of any payment by the
         non-paying Pool Debtor and/or if any of the circumstances described in
         sub-section 25.5 occur, the Pool Funds Administrator will forthwith
         repay to the Facility Bank by credit to the Pool Borrowing Account, if
         applicable, an amount equal, in the former case, to the amount so paid
         and, in the latter case, to the amount which should have been paid by
         the non-paying Pool Debtor.

25.7     Reduction in payments to Pool Creditors: a reduction in payments as
         contemplated by paragraphs 25.5.3 will also apply in the event of any
         amounts drawn down under

                                       855
<PAGE>
 
         the Credit Facility being required to be repaid in accordance with the
         terms of the Credit Facility and the Pool Funds Administrator shall
         account for such reduction in the Pool Ledger Accounts as amounts due
         and owing by the non-paying Pool Debtor to each Pool Creditor whose
         payments were reduced.

25.8     Enforcement of Claims and other provisions: Sub-sections 21.7, 21.8,
         21.9, 21.10 and Section 24 shall have effect in relation to amounts due
         from a non-paying Pool Debtor which arise under the foregoing
         sub-sections.

25.9     Unavailability of Credit Facility: if at any time the Credit Facility
         ceases to be unconditionally available and paragraph 15.1.2 shall
         thereupon have been effective, the whole or any part of the Security
         Cover thereby required to be provided by each Supplier may be provided
         by a credit to the Pool Reserve Account, unless otherwise determined by
         the Executive Committee. The Executive Committee shall from time to
         time assess (in consultation with the Pool Funds Administrator) and
         determine the amount of Security Cover which would be required pursuant
         to paragraph 15.1.2 as if that paragraph were in effect and such
         assessment and determination shall apply for the purposes of paragraph
         16.2.2 if paragraph 15.1.2 becomes applicable, pending any revised
         assessment by the Executive Committee.

25.10    Interpretation: terms and expressions used in this Section 25 shall,
         unless the context otherwise requires, have the same meanings as are
         given to them for the purposes of Clause 21.

                  circumstances.

                  (b)      cancel the Credit Facility unless either the approval
                           of the Executive Committee has been obtained of

         26.3.2   The Pool Funds Administrator shall cancel the Credit Facility
                  in full at any time if a resolution to that effect is passed

         calculated on the basis of those current on the date on which the
         relevant fee (or the relevant portion thereof) or additional amount is
         payable by the Pool Funds Administrator under the Credit Facility).

                  Committee so agree in writing and then on and subject to such
                  terms and conditions as are so agreed.

2.4      Wholly-owned subsidiary: NGC shall procure that, so long as EPFAL acts

2.5      Independent Contractor: in carrying out its duties and responsibilities
         and otherwise in acting as the Pool Funds Administrator under the
         Agreement, EPFAL shall act as an independent contractor and (unless
         expressly authorised to the contrary) shall neither act nor hold itself
         out nor be held out as acting as agent for any of the other Parties.

2.6      Restrictions on business: for so long as EPFAL is the Pool Funds

         to give rise to a conflict of interest in the performance by EPFAL of
         its duties and responsibilities as the Pool Funds Administrator under
         the Agreement. EPFAL further undertakes that if it carries on any
         business other than that of Pool Funds Administrator it shall maintain
         separate accounts and records in respect of any other business. EPFAL
         acknowledges and agrees that this undertaking has been the subject of
         discussion and negotiation and is fair and reasonable having regard to
         the revision of the terms and conditions of EPFAL's appointment as the
         Pool Administrator with effect from the PFA Commencement Date.

3.       EXPIRY OF TERM AND REMOVAL

         paragraphs 2.3.1 or 2.3.2, expiry of that extended or further extended
         term) the term of EPFAL'S appointment as the Pool Funds Administrator

         the request of the Executive Committee, continue to serve as the Pool
         Funds Administrator for such additional period not exceeding in
         accordance with paragraph 2.3.1 or 2.3.2, expiry of that extended or
         further extended term) as the Executive Committee may request in order
         to provide an opportunity for a successor to be appointed. The
         Executive Committee shall make such a request as soon as possible after
         becoming aware of the above circumstances but in any event no later
         than three months (or such other period as EPFAL and the Executive
         Committee may form time to time agree in writing) before the date of
         expiry of the Current Term or (as the case may be) the extended or
         further extended term.

3.2      Removal by Executive Committee: the Executive Committee may at any time

                  obligations as the Pool Funds Administrator under the
                  Agreement or the Agreed Procedures (other than a technical
                  breach of trust covered by the provisions contained in Section
                  5.16 of Schedule 11) and, if such breach is capable of remedy,

                           results in EPFAL'S inability to make such payment) or
                           a failure to call a Letter of Credit when required);

                           in any such case after it shall have received written
                           notice from the Executive Committee specifying the
                           breach and requiring it to be remedied; or

                           3.2.2) or if any voluntary agreement is proposed in

                           any scheme of arrangement other than for the purpose
                           of reconstruction or amalgamation upon terms and
                           within such period as may previously have been
                           approved in writing by the Executive Committee); or

                  (ii)     has an administration order under section 8 of the
                           Insolvency Act 1986 made in relation to it; or

                  (iv)     passes any resolution for winding-up other than a
                           resolution previously approved in writing by the
                           Executive Committee; or

                  the Insolvency Act 1986 shall have effect as if for
                  "(pound)750" there was substituted "(pound)150,000" and,
                  further, EPFAL shall not be deemed to be unable to pay its
                  debts for the purposes of sub-paragraph (i) above if any such
                  demand as is mentioned in the said section is being contested
                  in good faith by EPFAL with recourse to all appropriate
                  measures and procedures.

3.3      Acknowledgement: EPFAL acknowledges and agrees that, for the purposes
         of paragraph 3.2.1, any breach by it of its undertaking in sub-section

                  prejudice to paragraph 3.4.2) EPFAL's release as the Pool
                  Funds Administrator and (if appropriate) as a Party.

         8.2.1    in respect of the PFA Accounting Period beginning on the PFA
                  Commencement Date the Annual Fee for that PFA Accounting
                  Period shall be (pound)1,250,000 (the "Base Sum").

         8.2.2    In respect of each PFA Accounting Period beginning on an

                  (expressed in pounds sterling) for that PFA Accounting Period
                  shall be calculated in accordance with the following formula:-

                  (a)      ABS = Base Sum * (1+(RPIP/100))

                           where    RPIP = the percentage change (whether of a
                                    positive or negative value) in the Retail

         8.2.3    If during any PFA Accounting Period beginning on an
                  anniversary of the PFA Commencement Date the number of Active
                  Trading Pool Member Identities shall change such that, were
                  the Annual Fee for that PFA Accounting Period to be
                  recalculated, it would yield a different result from that
                  originally calculated for that PFA Accounting Period (or, as
                  the case may be, from that most recently recalculated for that
                  PFA Accounting Period pursuant to this paragraph 8.2.3) EPFAL
                  shall promptly recalculate the Annual Fee and notify the
                  Executive Committee in writing of the amount thereof. Such
                  notification shall be accompanied by a statement showing in
                  reasonable detail the calculation of such amount. Subject to
                  paragraph 8.3.2(b), such recalculated Annual Fee shall take
                  effect for the period from the date falling one month after
                  the receipt by the Executive Committee of such notification
                  until the end of the then current PFA Accounting Period (or
                  until further recalculated under this paragraph 8.2.3).

8.3      Review of fee:

         8.3.1    if at any time the total number of Active Trading Pool Member
                  Identities shall exceed 150 EPFAL may request the Executive
                  Committee to review the basis of calculation and/or the amount
                  of the Annual Fee. Upon receipt of such request the Executive
                  Committee and EPFAL shall negotiate in good faith for a period
                  not exceeding three months (or such longer period as EPFAL and
                  the Executive Committee may agree in writing) with a view to
                  agreeing a revised basis of calculation and/or amount of the
                  Annual Fee.

         8.3.2    (a) If EPFAL and the Executive Committee shall agree a revised
                  basis of calculation and/or amount of the Annual Fee, such
                  revisions shall take effect in accordance with the terms of
                  that agreement.

                  (b)      If at the end of the negotiation period referred to
                           in paragraph 8.3.1 EPFAL and the Executive Committee
                           shall not have agreed a revised basis of

                           calculation and/or amount of the Annual Fee or if the
                           Executive Committee shall dispute any calculation of
                           the Annual Fee made by EPFAL and notified to the
                           Executive Committee may refer the dispute to
                           arbitration pursuant to Clause 83. Pending the award
                           of the arbitrator(s) the Annual Fee current as at the
                           date of EPFAL's calculation or recalculation shall

         for an entire PFA Accounting Period submitted to the Executive
         Committee and, in the case of the Statement of Costs and Fees Pool
         Members pursuant to sub-section 9.1 or 10.1 shall be supported by a
         written report of EPFAL commenting in reasonable detail upon the
         matters comprised in the categories of expenditures included in such
         PFA Budget or Statement of Costs and Fees.

10.4     Tender Costs:

         10.4.1   if, during any PFA Accounting Period, the Pool Funds
                  Administrator reasonably believes that any of the category of
                  services within the definition of PFA Operating Costs are
                  likely to exceed the amount of that expenditure for that
                  category or sub- category or other items of cost provided for
                  in the PFA Budget by more than 5%, the Pool Funds
                  Administrator shall notify the Executive Committee accordingly
                  and explain the reasons for the increase. The Executive
                  Committee may required the Pool Fund Administrator to invite
                  tenders for any of the categories or sub-categories or items
                  of cost which are so exceeded, in accordance with sub-section
                  10.4.3.

         10.4.2   If the Executive Committee consider that the amount budgeted
                  for any category or sub-category or other item of cost in the
                  PFA Budget in unreasonable then the Executive Committee may
                  require the Pool Funds Administrator to invite tenders for any
                  of the categories or sub-categories or other items of cost in
                  the PFA Budget in accordance with sub-section 10.4.3.

         10.4.3   Within seven Business Day after receipt of a notice given
                  pursuant to paragraph 10.4.1 the Executive Committee shall
                  notify the Pool Funds Administrator in writing whether it
                  wishes the Pool Funds Administrator to seek a further tender
                  for the service in question. If the Executive Committee so
                  notifies the Pool Funds Administrator that it requires a
                  further tender to be sought, the Pool Funds Administrator
                  shall obtain a further tender and shall give the Executive
                  Committee reasonable details of that further tender and at the
                  same time shall notify the Executive Committee of which tender
                  it has chosen to accept together (if applicable) with reasons
                  as to why it has not chosen the lowest price tender.

         10.4.4   If the Executive Committee fails to notify the Pool Funds
                  Administrator within the time period referred to in paragraph
                  10.4.2 or notifies the Pool Funds Administrator that it does
                  not wish it to seek a further tender, the Pools Funds
                  Administrator may accept the original tender.

10.5     Basis of preparation: all Statement of Costs and Fees other than a
         Statement of Costs and Fees in respect of an entire PFA Accounting

         Statement of Costs and Fees in respect of an entire PFA Accounting
         Period shall be audited by EPFAL's auditors.

10.6     Accounting Practices: each PFA Budget and Statement of Costs and Fees
         shall be prepared on the basis of the accounting principles and
         practices used to draw up the most recent audited accounts of EPFAL and
         consistently applied. If any Statement of Costs and Fees for an entire
         PFA Accounting Period is not prepared on such basis, EPFAL shall
         prepare and submit to the Executive Committee and all Pool Members a
         pro-forma set of its audited accounts for such entire PFA Accounting
         Period which is prepared on the basis of the accounting principles and
         practices or their method of application used to prepare EPFAL's
         audited accounts shall be noted in the next following PFA Budget or
         Statement of Costs and Fees, as the case may be.

                  15.4) of EPFAL's annual charges referred to in sub-section
                  15.1 payable by each Pool Member for each PFA Accounting

                  each Pool Member or, where EPFAL and the Pool Member otherwise
                  agree, semi- annually in advance (calculated on a best
                  estimates and reasonable basis to be one twelfth or, as the
                  case may be, one half of the annual charges payable by such
                  Pool Member by reference to the most recent PFA Budget).

         15.2.2   EPFAL shall advise each Pool Member of such amount by invoice
                  despatched to each Pool Member approximately 15 days prior to
                  the first day of each month or, as the case may be, other
                  period. Such invoice shall be paid no later than the first day
                  of such month or such other period. Each Pool Member shall pay
                  the amount advised in the relevant invoice within 15 days

                  sterling in cleared funds in full without set off or
                  counterclaim, withholding or deduction of any kind whatsoever

         15.2.4   In the event of any dispute regarding charges in any month or
                  period, no Pool Member may withhold payment of any invoiced

                  with Clause 83.

15.3     Interest on non-payment: if any amount due to EPFAL, in its capacity as
         the Pool Funds Administrator is not received on the due date the Pool
         Member required to pay such amount shall pay interest to EPFAL on such
         amount from and including the date of default to the date of actual
         payment (as well after as before judgment) at the rate which is 4 per
         cent. per annum above the Base Rate from time to time of National
         Westminster Bank PLC during each period of default.

15.4     Payment of Charges: each Pool Member shall pay its due proportion of
         EPFAL'S charges for each PFA Accounting Period determined in accordance
         with Section 17.

15.5     Amount of Charges: the amount of each such payment shall be estimated
         initially by reference to the PFA Budget. EPFAL shall adjust the amount
         of each such payment by reference to the most recent Statement of Costs
         and Fees and so as to take into account PFA Operating Costs, the PFA
         Handling Charge, the Annual Fee and the Bank Charges during the
         previous PFA Accounting Period and anticipated costs in respect of the
         same during the current PFA Accounting Period and shall recover from
         or, as appropriate, credit to each Pool Member its due proportion of
         the difference between actual and anticipated PFA Operating Costs, the
         PFA Handling Charge, the Annual Fee and the Bank Charges and payments
         received in respect of such costs, fees and charges in each case for
         the previous and the current PFA Accounting Period. Such recovery or
         credit shall take place by reference to an adjustment to each Pool
         Member's charges for the current PFA Accounting Period.

         part only of any PFA Accounting Period shall pay charges on an interim
         basis of such amount as the Executive Committee estimates to be
         reasonable for such PFA Accounting Period on the basis of the
         allocation of charges set out in Section 17. Adjustments to charges on
         all Pool Members as a result of existing

                                       898

         following, and shall be set out in, the Statement of charges submitted
         for the relevant PFA Accounting Period pursuant to subsection 10.7
         whereupon the Pool Members and/or former Pool Members shall be required
         to pay such additional amount or be entitled to such reimbursement as
         may be determined in accordance with the Agreement by and adjustment to
         charges in the then current PFA Accounting Period.

16.      BANK CHARGES

         Bank Charges: EPFAL in its capacity as the Pool Funds Administrator
         shall collect from Pool Members the amounts they are obliged to pay by
         way of bank transaction charges towards the costs of the Pool Banker
         and all Settlement Banks ("Bank Charges") and shall account for the
         same to the Pool Banker and such Settlement Banks.

17.      ALLOCATION OF CHARGES

17.1     Total Sum Due: in respect of each PFA Accounting Period, the Total Sum
         Due shall be allocated amongst Pool Members in accordance with the
         following provisions of this Section 17.

17.2     Payment of Total Sum Due: each Pool Member shall be obliged to pay the
         amount allocated to it in accordance with this sub-section. The total
         aggregate amount allocated to all Pool Members in respect of any PFA
         Accounting Period shall equal the Total Sum Due in respect of such PFA
         Accounting Period.

17.3     Allocation of Total Sum Due: the Total Sum Due in respect of each PFA
         Accounting Period shall be allocated amongst Pool Members in the
         following manner:-

         17.3.1   first, in order to recover the discrete costs referable to
                  each Pool Member during any PFA Accounting Period, the costs
                  incurred by EPFAL, in its capacity as the Pool Funds
                  Administrator in complying with a request of such Pool Member
                  made pursuant to Clause 63.1.7 or sub-section 6.3 of Schedule
                  which are directly referable to such Pool Member shall, as far
                  as possible, be allocated to such Pool Member; and

         17.3.2   secondly, 100 per cent. of the balance of the Total Sum Due
                  during any PFA Accounting Period not recovered pursuant to
                  paragraph 17.3.1 shall be allocated amongst all Pool Members
                  during such PFA Accounting Period according to their
                  respective Contributory Shares for such PFA Accounting Period.

17.4     Prima facie evidence: EPFAL's determination of the allocation of all
         costs during any PFA Accounting period shall, in the absence of
         manifest error, be prima facie evidence thereof.

18.      ADJUSTMENT

         If the Executive Committee requests EPFAL to continue to serve as the
         Pool Funds Administrator pursuant to sub-section 3.1 to allow a
         successor to be appointed, EPFAL and the Executive Committee shall
         negotiate in good faith for a period not exceeding six weeks (or such
         longer period as EPFAL and the Executive Committee) may agree in
         writing) with a view to agreeing a revision in the amount of the Base
         Sum to be used in the calculation of the Annual Fee for the duration of

                                       899
<PAGE>
 
         the additional period referred to in sub-section 3.1. If EPFAL and the
         Executive Committee shall agree to revise the amount of the Base Sum,
         such revision (and any consequential revision in the Annual Fee) shall
         take effect in accordance with the terms of that agreement. If no
         agreement is reached within the said negotiation period the Executive
         Committee or EPFAL may refer the dispute to arbitration pursuant to
         Clause 83. Pending any such agreement being reached or any such dispute
         being resolved by arbitration, EPFAL shall continue to serve as the
         Pool Funds Administrator for the additional period referred to in
         sub-section 3.1.

19.      ADDITIONAL COMPENSATION

19.1     General: a direction or instruction of the Executive Committee to EPFAL
         in its capacity as the Pool Funds Administrator shall not materially
         increase the duties, responsibilities or liabilities of EPFAL as the
         Pool Funds Administrator beyond those detailed in the Agreement as at
         the PFA Commencement Date and as detailed in the Agreed Procedures
         without proper compensation.

19.2     Compensation: if the Executive Committee gives a direction or
         instruction to EPFAL in its capacity as the Pool Funds Administrator
         which materially increases the duties, responsibilities or liabilities
         of EPFAL as the Pool Funds Administrator beyond those detailed in the
         Agreement as at the PFA Commencement Date and a detailed in the Agreed
         Procedures, then (subject to sub-section 19.3):-

         19.2.1   EPFAL shall carry out that direction or instruction unless it
                  has reasonable grounds for refusing so to do in which event it
                  shall forthwith notify the Executive Committee in writing of
                  its refusal and its reasons therefor (and, for this purpose,
                  an increase in the duties, responsibilities or liabilities of
                  EPFAL in its capacity as the Pool Funds Administrator shall
                  not of itself constitute reasonable grounds);

         19.2.2   EPFAL and the Executive Committee shall negotiate in good
                  faith for a period not exceeding one month (or such longer
                  period as EPFAL and the Executive Committee may agree in
                  writing) with a view to agreeing an appropriate increase in
                  the Base Sum to reflect such increase in EPFAL's duties,
                  responsibilities and liabilities as the Pool Funds
                  Administrator;

         19.2.3   if EPFAL and the Executive Committee shall agree an increase
                  in the Base Sum, such increase shall take effect in accordance
                  with the terms of that agreement; and

         19.2.4   if there shall be any dispute as to whether that direction or
                  instruction does or did materially increase the duties,
                  responsibilities or liabilities of EPFAL, as the Pool Funds
                  Administrator or whether EPFAL has reasonable grounds for
                  refusing to carry out that direction or instruction or if no
                  agreement is reached under paragraph 19.2.9, EPFAL or the
                  Executive Committee may refer to the dispute to arbitration in
                  accordance with Clause 83.

19.3     Reservation: the performance by EPFAL of any direction or instruction
         of the Executive Committee shall not prevent EPFAL from later claiming
         that such direction or instruction materially increased its duties,
         responsibilities or liabilities as the Pool Funds Administrator
         provided always that EPFAL shall not be entitled so to claim unless it
         gave written notice to the Executive Committee promptly (and in any
         event within seven days) after first becoming aware that such direction
         or instruction

                                       900
<PAGE>
 
         materially increased or was likely materially to increase such duties,
         responsibilities or liabilities, such notice to contain detailed
         reasons in support of why there has been or is likely to be such an
         increase.

                  sub-section 20.6 their respective proportionate share of the
                  Pool Administration Costs (together with Value Added Tax
                  thereon, if applicable) against receipt of an invoice or other
                  statement therefor issued by EPFAL and otherwise in accordance
                  with paragraph 20.5.1;

         20.5.1   EPFAL shall arrange for collection from Pool Members of their
                  respective proportionate share of the Pool Administration
                  Costs in such manner as may be agreed by EPFAL with the
                  Executive Committee from time to time (which may include
                  collection in advance) and Pool Members shall comply with such
                  collection procedures and, in particular, shall make payment
                  within the time period prescribed by such procedures. The

         PFA Accounting Period and shall form part of the Pool Administration
         Costs for that PFA Accounting Period (spread evenly so far as

                  4 application or if the Executive Committee shall determine
                  that the Nominated Site the subject of a Class 1, Class 2 or
                  Class 3 Trading Site Application does not satisfy the
                  conditions specified in paragraph 2, 3 or (as the case may be)
                  4, the Executive Committee shall determine from the Trading
                  Site Application and supporting documentation and other
                  matters (and any further evidence provided in accordance with

         5.2      The criteria referred to in paragraph 5.1 are:-

                  (a)      whether special circumstances existed before 30th
                           March, 1990 which demonstrate to the reasonable
                           satisfaction of the Executive Committee that the
                           generation and demand were treated as being on a
                           Trading site;


                                       912
<PAGE>
 
                  (b)      whether special circumstances existed before 11th
                           December, 1991 which demonstrate to the reasonable
                           satisfaction of the Executive Committee that the
                           generation and demand should have been treated as on
                           a Trading Site;

                  (c)      whether, although not satisfying the conditions
                           applicable to a Class 1, Class 2 or Class 3 Trading
                           Site Application, if, to the reasonable satisfaction
                           of the Executive Committee, the Trading Site
                           Application demonstrates sufficient similarities with
                           sites which would satisfy those conditions such that
                           it would be unreasonable not to treat the Nominated
                           Site as a Trading Site;

                  (d)      whether there are any other facts or evidence in
                           support of the Trading Site Application which in the
                           reasonable opinion of the Executive Committee
                           demonstrate that the Nominated Site ought to be
                           treated as a Trading Site.

6.       Further evidence: the Executive Committee may request an Applicant to
         produce such further evidence as the Executive committee may reasonably
         require in support of its Trading Site Application before the Executive
         Committee makes any determination as to whether the Nominated Site is
         to be treated as a Trading Site, and the Executive Committee shall not
         be bound to make any determination on the issue of whether the
         Nominated Site is a Trading site pending receipt of such further
         evidence.

7.       Majorities: any determination of the Executive Committee in favour of
         treating a Nominated Site as a Trading site shall require a simple
         majority of the votes cast by Committee Members at the relevant meeting
         provided that in the case of a Trading Site Application which falls to
         be considered under paragraph 5 the necessary majority shall be 75 per
         cent of all the votes cast by Committee Members.

8.       Effect of determination: if the Executive Committee shall determine
         pursuant to paragraph 2, 3, 4 or (as the case may be) 5 that a
         Nominated Site is a Trading Site all metered values of all meters
         associated with the Nominated Site and identified in the Trading Site
         Application shall be aggregated in accordance with the provisions of
         sub-section 3.3 of, and paragraph 2F of Appendix 6 to, Schedule 9.

                  nature of the changes upon Meter Operators Parties as a class
                  and shall not have locus standi to consider any perceived or
                  actual prejudice as an individual Meter Operator Party.

         each Meter Operator Party hereby unconditionally and irrevocably
         authorises and instructs the Chief Executive and each person authorised

         amending agreements to this Agreement, to execute any agreement which
         modifies, abrogates, amends or suspends any provision of this Agreement
         in circumstances where such Meter Operator Party's consent or approval
         is not required, and undertakes not to withdraw, qualify or revoke such
         authority and instruction at any time.

2.4      Notification: the Executive Committee shall notify each Meter Operator
         Party of all amendments, modifications, abrogations and suspensions
         which are made to this Agreement for which the consent or agreement of

2.5      Further rights: the Executive Committee shall from time to time
         consider any representations which Meter Operator Parties may make to
         the effect that there are provisions set out in the Agreement but not
         in this Schedule 21 and, accordingly, in respect of which Meter
         Operator Parties are not conferred with rights by virtue of this
         paragraph 2, which are operating in a manner which is having a material
         effect on the rights and liabilities of such Meter Operator Parties as
         set out herein. The Executive Committee shall consider whether, and the
         extent to which (if at all), such provisions should be recommended for
         incorporation into this Schedule 21.

                  the New Meter Operator Party and the Director either:

                  (a)      that the New Meter Operator Party shall be admitted
                           as a Meter Operator Party, in which even the
                           provisions of paragraph 3.5 shall apply; or

                  (b)      that the Executive Committee has received an
                           objection, or objections, to the admission of that

                           considers the application to be frivolous or
                           vexatious and for that reason is rejecting the
                           application without further right of appeal; or

                  (c)      that the Executive Committee has received an
                           objection, or objections, to the admission of that
                           New Meter Operator Party in accordance with paragraph
                           3.3.2 and has referred the matter to the Director in

                           have) been received and the Executive Committee has
                           not notified the New Meter Operator Party that it is
                           rejecting its application on the basis that those
                           objections demonstrate that the relevant application
                           is frivolous or vexatious; or

                  (b)      the Executive Committee shall have failed to notify
                           the New Meter Operator Party as provided in paragraph

                  the matter may be referred by way of written application of
                  the New Meter Operator Party, copied to the Executive
                  Committee, to the Director for determination. The
                  determination of the Director, which shall be made within 28
                  days after receipt of the said written application and shall

                  purposes. The Director shall publish reasons supporting his
                  determination.

3.4.2    (a) If the determination is to the effect that the New Meter Operator
         Party should be admitted as a Meter Operator Party, the New Meter
         Operator Party shall be admitted and the provisions of paragraph 3.5
         shall apply.

                  Operator Party should not be admitted as a Meter Operator
                  Party, the New Meter Operator Party's application for
                  admission shall lapse and be of no effect and the New Meter
                  Operator Party shall not be, and shall not be entitled to be,
                  admitted as a Meter Operator Party consequent upon such
                  application (but without prejudice to any new application it
                  may make thereafter).

3.5      Admission: if:

         pay all costs and expenses associated with the preparation, execution
         and delivery of its Meter Operator Party Accession Agreement. Each
         Party and Meter Operator Party hereby authorises and instructs the
         Chief Executive and each person authorised for the purpose by the Chief
         Executive to sign on its behalf Meter Operator Party Accession
         Agreements and undertakes not to withdraw, qualify or revoke such
         authority and instruction at any time. The Executive Committee shall

         compliance by any person with the provisions of this paragraph 3 with
         regard to its admission as a Meter Operator Party shall not of itself
         mean that all things have been done and agreements or arrangements have
         been entered into with other Parties and persons such that the duly
         admitted Meter Operator Party is entitled or enabled to comply as an
         operational, physical or legal matter with its obligations, or to enjoy
         its rights, as an Operator under this Schedule and the provisions of

         other conditions as the Executive Committee may from time to time
         reasonably specify) and upon request from time to time shall promptly
         provide the Executive Committee with evidence reasonably satisfactory
         to the Executive Committee of such satisfaction and compliance.

         Administrator) (in this paragraph 20, the "Party Liable") or any of its
         officers, employees or agents shall be liable to any of the other
         Parties or Meter Operator Parties for loss arising from any breach of
         this Schedule or of this Agreement other than for loss directly

                  the property or any other person.

20.2     Death and personal injury: Nothing in this Schedule or this Agreement
         shall exclude or limit the liability of the Party Liable for death or

         death or personal injury resulting from the negligence of the Party
         Liable or any of its officers, employees or agents.

20.3     Exclusion of certain types of loss: Subject to paragraph 20.2 and save
         where any provision of this Agreement provides for an indemnity,
         neither the Party Liable nor any of its officers, employees or agents
         shall in any circumstances whatsoever be liable to any of the other
         Parties or Meter Operator Parties for:

         20.3.1   any loss of profit, loss of revenue, loss of use, loss of
                  contract or loss of goodwill; or

         20.3.2   any indirect or consequential loss; or

         20.3.3   loss resulting from the liability of any other Party or Meter

         as trustee and agent for its officers, employees and agents.

20.5     Survival: Each of paragraphs 20.1, 20.2, 20.3 and 20.4 shall:

         20.5.1   be constructed as a separate and severable contract term, and
                  if one or more of such paragraphs is held to be invalid,
                  unlawful or otherwise unenforceable the other or others of
                  such paragraphs shall remain in full force and effect and
                  shall continue to bind the Parties and the Meter Operator
                  Parties; and

         20.5.2   survive the termination of this Agreement.

20.6     Saving: For the avoidance of doubt, nothing in this Part 8 shall
         prevent or restrict any Party or Meter Operator Party enforcing any
         obligations (including suing for a debt) owed to it under or pursuant
         to this Schedule or this Agreement.

                  the case may be, Party (and all employees and/or contractors
                  who may be authorised from time to time to exercise such right
                  of access) of any relevant directions or regulations made by

         Each Party or Meter Operator Party shall (and shall procure that all
         persons exercising any right of access on behalf of such Party or Meter
         Operator Party) observe and perform any such arrangements and all
         provisions (or directions or regulations issued pursuant thereto) made
         from time to time.

                                       960
<PAGE>
 
         (b)      cause as little disturbance and inconvenience as possible to
                  any Meter Operator Party, Party, Second Tier Customer or other
                  Third Party or other occupier of such Meter Operator Party's,
                  Party's, Second Tier Customer's or other Third Party's
                  property,

         and shall make good any damage caused to such property in the course of
         exercise of such rights as soon as may be practicable. Subject to this,

         (a)      this paragraph 21.9 shall apply to any area owned or occupied
                  by any Party, Meter Operator Party or any subsidiary of such
                  Party or Meter Operator Party, Second Tier Customer or Third
                  Party (each a "Licence Restricted Party") which is the holder
                  of or subject to a licence granted under the Nuclear
                  Installations Act 1965 (a "Nuclear Site Licence") or subject
                  to restrictions in relation to a Nuclear Site Licence, where

                  respect of Energy Settlements and Information Services
                  Limited, this paragraph 21.9 shall apply subject to the
                  provisions of any other agreement between the Licence
                  Restricted Party and NGC (or any of its subsidiaries) imposing
                  restrictions on NGC's (or any of its subsidiaries') right of
                  access to any areas owned by the Licence Restricted Party
                  subject to (or subject to restrictions in relation to) a
                  Nuclear Site Licence.

                  affecting access to its property as it considers on reasonable
                  grounds to be necessary in order to enable the Licence
                  Restricted Party to comply with the provisions, restrictions
                  and conditions of a Nuclear Site Licence or avert or minimise
                  any reasonably anticipated breaches thereof.

21.10    Denial of access: The Settlement System Administrator shall not incur

                                     PART 10

                            COMMUNICATIONS EQUIPMENT

22.      COMMUNICATIONS EQUIPMENT

22.1     Compatibility: Communications Equipment at any City (which whenever
         used in this paragraph 22 shall include all Qualifying Sites determined
         in accordance with the first Tariff published at or after the date the
         ninth supplemental deed to this Agreement comes into effect) must be
         compatible with the communications link to such Site provided by the
         Settlement System Administrator pursuant to Clause 60.6.3(a). Prior to
         the installation of Communications Equipment at any Site the Operator
         or Potential Operator shall consult with the Settlement System
         Administrator to ensure that such Communications Equipment will be
         compatible with such communication link. The Operator or Potential
         Operator shall notify the Settlement System Administrator of any use to
         which the Communications Equipment is put other than in connection with
         Settlement.

22.2     General principle: Subject to the requirement of the Settlement System
         Administrator to collect data in accordance with Clause 60.6.1 and
         subject to the provisions of paragraph 22.1, the Settlement System
         Administrator shall use all reasonable endeavors to ensure that the
         communications link provided by it to any Embedded Non-Franchise Site
         pursuant to Clause 60.6.3(a) is of the type requested by the Operator
         or Potential Operator.

22.3     Tariff payments: The Settlement System Administrator shall pay from
         time to time to each Operator or Potential Operator of a Metering
         System at a Site an amount (if any) determined in accordance with the
         Tariff and payable in respect of Communications Equipment installed and
         maintained at such Site by such Operator or Potential Operator for the
         purposes of this Agreement.

22.4     Refunds: Where an Operator is removed, resigns or otherwise ceases to
         be Operator at any Site it shall pay to the Settlement System
         Administrator such amount (if any) as is set out in the Tariff by way
         of reimbursement of amounts paid to it pursuant to paragraph 22.3.

22.5     Additional payments: If an Operator or Potential Operator can
         demonstrate to the reasonable satisfaction of the Settlement System
         Administrator that any relevant payment to be made pursuant to this
         paragraph 22 and in accordance with the Tariff in respect of any
         particular Site as is described in the Tariff does not reflect the cost
         to such Operator or Potential Operator of installing and maintaining
         Communications Equipment at such Site in an efficient and economic
         manner then the Settlement System Administrator may negotiate an
         additional payment to such Operator or Potential Operator in respect of
         Communications Equipment at such Site provided that the Operator or
         Potential Operator shall be entitled to receive such additional payment
         only if and to the extent that the economic and efficient installation
         and maintenance of the Communications Equipment at that Site is in fact
         effected. If the Operator or Potential Operator and the Settlement
         System Administrator fail to agree on the amount of an additional
         payment, the Operator or Potential Operator may refer the matter to the
         Executive Committee which shall determine the same. The relevant Meter

         rights and obligations under any agreement or arrangement relating to
         being an Operator entered into or existing between the Parties or any
         of them prior to such deemed admission, and that accordingly such

         any reference to that Party being an Operator under this Agreement
         shall be construed as being an Operator as a Meter Operator Party.

23.2     Saving: Notwithstanding paragraph 23.1, each Party to which this Part
         11 applies, expressly acknowledges and agrees that, notwithstanding any
         deemed satisfaction of the conditions which are required to be

         purposes of admission as a Meter Operator Party and as Operator it
         shall be subject (but only with prospective

         effect; that is to say to the effect that any conditions which apply as
         at the NSD Date are deemed to be fulfilled and need not then be
         fulfilled as a continuing obligation) to the continuing and further
         conditions for registration as an Operator from time to time and to the
         provisions of paragraph 4.4, and that it shall be subject to the
         provisions for the resignation, removal and cessation as Operator in
         respect of any Metering System, or as Meter Operator Party, as the case
         may be, in accordance with the provisions of this Schedule as at the
         date hereof and from time to time, and after any such resignation,
         removal or cessation as a Meter Operator Party it shall be subject in
         full to the procedures for admission as a Meter Operator Party and
         Operator as may be set out from time to time in this Schedule.

NOW IT IS HEREBY AGREED AS FOLLOWS:

1.    INTERPRETATION AND CONSTRUCTION

1.1   In this Agreement and in each Supplemental Agreement the words and
      expressions defined in Schedule 2 shall, unless the subject matter or
      context otherwise requires or is inconsistent therewith, apply.

1.2   In the event of any inconsistency between the provisions of any
      Supplemental Agreement and this Agreement, the provisions of the
      Supplemental Agreement shall prevail in relation to the Connection Site
      which is the subject thereof to the extent that the rights and obligations
      of Users not party to that Supplemental Agreement are not affected.

1.3   If in order to comply with any obligation in this Agreement or any
      Supplemental Agreement any Party is under a duty to obtain the consent or
      approval (including any statutory licence or permission) ("the Consent")
      of a third party (or the consent of another Party to this Agreement) such
      obligation shall be deemed to be subject to the obtaining of such Consent
      which the Party requiring the consent shall use its reasonable endeavors
      to obtain including (if there are reasonable grounds therefor) pursuing
      any appeal in order to obtain such Consent.

      1.3.1. If such Consent is required from any Party to this Agreement then
             such Party shall grant such Consent unless it is unable to do so or
             it would be unlawful for it to do so provided that such grant by
             such Party may be made subject to such reasonable conditions as 
             such Party shall reasonably determine.

      1.3.2. For the avoidance of doubt if the Party who is under a duty to
             obtain such Consent fails to obtain such Consent having complied
             with this Clause 1.3 the obligation on that Party (in relation to
             which such Consent is required) shall cease.

            to Clause 13.
 
     2.5.3. NGC shall notify the relevant owner or operator of the Distribution
            System in writing as soon as the conditions set out in Sub-Clause

            case together with, if appropriate, a copy of Appendix A of
            Supplemental Agreement Type 5. NGC undertakes to each Party that,
            for so long as it is the case, NGC shall from time to time forthwith
            upon receipt of any written request from that Party to do so,
            confirm in writing to any person specified in such request that that
            Party is a party to this Agreement and any Supplemental Agreement
            specified in such request.
 
     2.5.4. Each owner or operator of a Distribution System shall Deenergise
            the connection equipment of any such User the subject of Sub-Clause

            reasonably practicable following the instruction of NGC in
            accordance with the terms of this Agreement. NGC shall reimburse
            such owner or operator any expense incurred in relation to such act
            of Deenergisation, if any, and shall indemnify such owner or
            operator against any liability, loss or damage suffered by it as a
            result of such Deenergisation. Details of any circumstances likely
            to lead to such a Deenergisation shall be notified promptly by NGC
            to the said owner or operator. The owner or operator of a
            Distribution System shall promptly notify NGC when the connection

      from time to time will constitute separate agreement governed by the terms
      of this Master Agreement and will be read and construed accordingly. For

6.    PRINCIPLES OF OWNERSHIP

6.1   Ownership - electrical boundaries

      Subject to the Transfer Scheme or any contrary agreement in this
      Agreement, any Supplemental Agreement or elsewhere the division of
      ownership of Plant and Apparatus shall be at the electrical boundary, such
      boundary to be determined in accordance with the following principles:

      (i)   In relation to Plant and Apparatus located between the NGC
            Transmission System and a Power Station, the electrical boundary is
            at the busbar clamp on the busbar side of the busbar isolators on
            Generators and Power Station transformer circuits;

      (ii)  save as specified in Clause 6.1(iii) below, in relation to Plant and
            Apparatus located between the NGC Transmission System and a
            Distribution System, the electrical boundary is at the busbar clamp
            in the busbar side of the Distribution System voltage busbar
            selector isolator(s) of the NGC Transmission System circuit or, if a
            conventional busbar does not exist, an equivalent isolator. If no
            isolator exists an agreed bolted connection at or adjacent to the
            tee point shall be deemed to be an isolator for these purposes;

      (iii) in relation to Plant and Apparatus located between the NGC
            Transmission System and a Distribution System and owned by NGC but
            designed for a voltage of 132KV or below, the electrical boundary is
            at the busbar clamp on the busbar side of the busbar selector
            isolator on the Distribution System circuit or, if a conventional
            busbar does not exist, an equivalent isolator. If no isolator
            exists, an agreed bolted connection at or adjacent to the tee point
            shall be deemed to be an isolator for these purposes; and

      (iv)  in the case of a metal clad switchgear bay the electrical boundary
            will be the equivalent of those specified in this Clause 6.1 save
            that:


                                       10
<PAGE>
 
            (a)   for rack out switchgear, the electrical boundary will be at
                  the busbar shutters;

            (b)   for SF6 switchgear, the electrical boundary will be at the gas
                  zone separators on the busbar side of the busbar selection
                  devices.

6.2   If a User wants to use transformers of specialised design for unusual load
      characteristics at the electrical boundary, NGC shall own such
      transformers but the User shall pay NGC for the proper and reasonable
      additional cost thereof as identified by NGC in the Offer covering such
      transformers. In this Sub-Clause 6.2 "unusual load characteristics" means
      loads which have characteristics which are significantly different from
      those of the normal range of domestic, commercial and industrial loads
      (including loads which vary considerably in duration or magnitude).

6.3   For the avoidance of doubt nothing in this Clause 6 shall effect any
      transfer of ownership in any Plant or Apparatus.

7.    METERING

7.1   Each User consents to NGC having access to and copies of all meter
      readings taken from Energy Metering Equipment pursuant to the Pooling and
      Settlement Agreement in any Financial Year for the purposes of calculating
      Connection Charges and Use of System Charges due from Users or for the
      purpose of operating the NGC Transmission System. Such access and copies
      shall be obtained from the Settlement System Administrator appointed under
      the Pooling and Settlement Agreement from time to time provided always
      that if the Settlement System Administrator fails to provide such access
      and copies at NGC's request the User shall supply any such meter readings
      in the possession of the User direct to NGC.


                                       11
<PAGE>
 
7.2   The relationship between the Parties hereto with respect to Energy
      Metering Equipment shall be regulated by Part XV of the Pooling and
      Settlement Agreement.

7.3   In respect of Operational Metering Equipment owned by the Party and in
      respect of which access and rights to deal with such Operational Metering
      Equipment are not set down in any other document the Parties shall grant
      each other such access and the rights as are reasonably necessary to
      enable them to perform their obligations under this Agreement and the Grid
      Code upon presentation of a suitable indemnity and the Parties shall take
      such action as may be necessary to regularise the position forthwith
      thereafter.

8.    NGC OBLIGATIONS

8.1   NGC agrees with each User to make available, plan, develop, operate and
      maintain the NGC Transmission System in accordance with the NGC
      Transmission Licence and with the Grid Code subject to any Derogations
      from time to time.

9.    COMPLIANCE WITH THE GRID CODE/DISTRIBUTION CODE

9.1   Subject to Sub-Clause 9.3 each Party agrees with each other Party to be
      bound by and to comply in all respects with the provisions of the Grid
      Code in so far as applicable to that Party.

9.2   Subject to Sub-Clause 9.3 each Party agrees with each other Party to be
      bound by and to comply in all respects with the provisions of the relevant
      Distribution Code(s) in so far as applicable to that Party except as may
      be otherwise provided in any agreement for connection to a Distribution
      System.

9.3   Neither NGC nor a User need comply with the Grid Code or any relevant
      Distribution Code(s) to the extent (if any) that:


                                       12
<PAGE>
 
      (i)   either the Director has issued directions relieving NGC or that User
            from the obligation under its respective licence to comply with the
            Licence Standards, the Grid code or any relevant Distribution
            Code(s) in respect of such parts of the Grid Code or any relevant
            Distribution Code(s) respectively as may be specified in those
            directions or to the extent that NGC and a User which does not have
            a Licence under the Act can and have so agreed in any Supplemental
            Agreement in relation to any Connection Site or New Connection Site
            and/or Derogated Plant; or

      (ii)  (in the case of a User) the Grid Code relates to the provision by
            that User of any Ancillary Services unless there is an Ancillary
            Services Agreement in force between that User and NGC for the
            payment by NGC for such Ancillary Services; or

      (iii) (in the case of NGC) the Grid Code imposes any obligation on NGC to
            make available Additional Scheduling Data (as defined in the Grid
            code) before 31st December 1990.

9.4   In this Sub-Clause 9.4 the following expressions shall bear the following
      meanings:

      "Required Standard"       In relation to an item of Derogated Plant, the
                                respective standard required of that item (which
                                shall not exceed that required by the Grid code
                                or the Licence Standards, as the case may be) as
                                specified in or pursuant to the relevant
                                Derogation;

      "Back                     Stop Date" in relation to an item of Derogated
                                Plant, the date by which it is to attain its
                                Required Standard, as specified in or pursuant
                                to the relevant Derogation.


                                       13
<PAGE>
 
      Each User undertakes to NGC and NGC undertakes to each User to use all
      reasonable endeavours to carry out such works as are necessary to ensure
      that each item of Derogated Plant owned or operated by that User or NGC
      (as appropriate) is brought up to the Required Standard applicable to it
      no later than the Back stop Date applicable to it.

9.5   The terms and provisions of the Fuel Security Code shall prevail to the
      extent that they are inconsistent with the Grid code or any Distribution
      code and the Parties' obligations under this Agreement shall be construed
      accordingly.

10.   MODIFICATIONS

10.1  No modification may be made by or on behalf of a User or NGC otherwise
      than in accordance with the provisions of this Clause 10.

12.   GENERAL PROVISIONS CONCERNING MODIFICATIONS AND NEW CONNECTION SITES

12.1  subject to the payment of its Reasonable Charges, if any, as provided for
      in this Sub-Clause NGC undertakes to each User to provide all advice and
      assistance reasonably requested by that User to enable that User
      adequately to assess the


                                       16
<PAGE>
 
      implications (including the feasibility) of making a Modification to the
      User's Equipment or the Users System (whether such Modification is to be
      made at the request of NGC or of the User) or of constructing a New
      Connection Site (including adequately assessing the feasibility of making
      any Connection Application or considering the terms of any Connection
      Offer). If the proposed Modification by the User is or may be required as
      a result of a Modification proposed by NGC then NGC shall provide such
      advice and assistance free of charge. If the proposed Modification is or
      may be proposed by the User or if the advice and assistance is in respect
      of a New connection Site NGC may charge the User Reasonable charges for
      such advice and assistance. The provisions of such advice and assistance
      shall be subject to any confidentiality obligations binding on NGC and
      that User.

12.2  When giving such advice and assistance NGC shall comply with Good Industry
      Practice.

12.3  NGC shall have no obligation to compensate any User (the "First User") for
      the cost or expense of any Modification required to be made by any User as
      a result of any NGC Modification under Sub-Clause 10.3.1. Where such NGC
      Modification is made as a result of the construction of a New Connection
      Site or a Modification for another User (the "Other User"), the Other User
      shall compensate the First User for the reasonable and proper cost and
      expense of any Modifications required to be made by the First User as a
      result of that NGC Modification. Such compensation shall be paid to the
      First User by the Other User within thirty days of production to the Other
      User of a receipted invoice (together with a detailed breakdown of such
      reasonable costs and expenses) for the expenditure which has been incurred
      by the First User.

      Modification Offers and Connection Offers

      If at the time of making any Offer or Modification Offer or Connection
      Offer to a User ("the Second Offer") there is an outstanding Modification
      Offer(s) or Connection Offer(s) to another User(s) ("the First Offer")
      which if accepted would affect the terms of the Second Offer NGC shall at
      the time of making the Second Offer.

      (i)   inform the recipient(s) of both the First Offer(s) and Second
            Offer(s) in writing that there is another Offer outstanding which
            might affect them; and

      (ii)  be entitled to make the First Offer(s) and Second Offer(s)
            conditional upon other outstanding Offers not having been or being
            accepted; and

      (iii) be entitled to vary the terms of either Offer if the other Offer is
            accepted first on the same procedures as those set out in Clauses
            10.2.2 to 10.2.4 or 11.2 to 11.4 inclusive as the case may be.

13.   ADDITIONAL PARTIES

13.1  The Parties shall admit as an additional party to this Master Agreement
      any person who accepts a Connection Offer from NGC or any new Embedded
      User (the "New Party") and who is not at the time already a Party. Such
      admission shall take effect by way of Accession Agreement prepared by NGC
      at the expense and cost of the New Party and to be executed by NGC for
      itself and on behalf of all other Parties. Upon execution of the Accession
      Agreement by NGC and the New Party and subject to the terms and conditions
      of that Accession Agreement, the New Party shall become a Party for all
      purposes of this Agreement.


                                       18

            event within 28 days of receiving notice of such change and until
            such consideration is complete the transfer shall not be effective.
            If having considered such changes NGC in its reasonable opinion does
            not consider the proposed changes reasonably satisfactory to NGC it
            shall consult with the User seeking to undertake such transfer and
            pending the outcome thereof to NGC's reasonable satisfaction the
            transfer shall not be effective provided always that the User may
            refer any dispute to the Disputes Resolution Procedure. such

            Disputes Resolution Procedure;

      (ii)  upon the disposal by a User of part of its business undertaking
            comprising User's Equipment at one or more Connection Sites that
            User shall have the right to transfer its rights and obligations
            under all relevant Supplemental Agreements to the purchaser thereof
            on condition that the purchaser (if not already a User) enters into
            an Accession Agreement with NGC under Clause 13 and confirms to NGC
            in writing either that all of the technical or related conditions,
            data, information, operational issues or other matters specified in
            or pursuant to the relevant Supplemental Agreement(s) or Grid Code
            by the User seeking the transfer will remain unchanged or, if any
            such matters are to be changed, the purchaser first notifies NGC in
            writing of such changes which NGC will consider promptly and in any


                                       27
<PAGE>
 
            event within 28 days of receiving notice of such change and until
            such consideration is complete the assignment shall not be
            effective. If having considered such changes NGC in its reasonable
            opinion does not consider the proposed changes reasonably
            satisfactory to NGC it shall consult with the User seeking to
            undertake such transfer and pending the outcome thereof to NGC's
            reasonable satisfaction the transfer shall not be effective provided
            always that the User may refer any dispute to the Disputes
            Resolution Procedure. Such transfer shall become effective once the
            changes are reasonably satisfactory to NGC or have been determined
            to be so under the Disputes Resolution Procedure;

      performance of any of its obligations or duties arising under this
      Agreement or any Supplemental Agreement including activities envisaged by

      sub-contracting by a Party of the performance of any obligations or duties

25.2  NGC and each User acknowledges that, because there has been insufficient
      time to discuss and agree the details of the Appendices to each
      Supplemental Agreement, those details may be inaccurate. Accordingly,

      (a)   each User and NGC undertake to discuss in good faith the correct
            identification of the details of each part of Appendix F of each
            Supplemental Agreement entered into between NGC and the User with a
            view to amending the same as necessary to reflect the correct
            position. To the extent that agreement on the correct position
            cannot be reached within 12 months after the date of that
            Supplemental Agreement the matter shall be referred to arbitration
            for determination in accordance with Clause 26 of this Agreement and
            such details shall be amended accordingly following such agreement
            or determination (as the case may be); and

      (b)   in relation to Appendix A of each Supplemental Agreement, NGC
            undertakes to establish a new asset register, specifying all Plant
            and Apparatus owned by NGC which is necessary to connect each User's
            Equipment to the NGC Transmission System at each Connection Site,
            during the course of the Financial Year ending 31st March 1991 in
            accordance with paragraph 2.2 of Appendix E to such Supplemental
            Agreement. Such new asset register shall, provided that NGC has
            complied with such paragraph 2.2, take effect from 1st April 1991.
            Following the establishment of such new asset register, each such
            Appendix A and any provisions of the relevant Supplemental Agreement
            which refer to it shall, to the extent appropriate, be amended
            accordingly.

26.   DISPUTE RESOLUTION

26.1  Save where expressly stated in this Agreement to the contrary and subject
      to any contrary provision of the Act, any License, or the Regulations, or
      the rights,


                                       39
<PAGE>
 
      powers, duties and obligations of the Director or the Secretary of State
      under the Act, any License or otherwise howsoever, any dispute or
      difference of whatever nature howsoever arising under out of or in
      connection with this Agreement between any one or more Parties hereto
      shall be and is hereby referred to arbitration pursuant to the arbitration
      rules of the Electricity Supply Industry Arbitration Association in force
      from time to time.

26.2  Whatever the nationality, residence or domicile of any Party to this
      Agreement and wherever the dispute or difference or any part thereof arose
      the law of England shall be the proper law of any reference to arbitration
      hereunder and in particular (but not so a to derogate from the generality
      of the foregoing) the provisions of the Arbitration Acts 1950
      (notwithstanding anything in section 34 thereof) to 1979 shall apply to
      any such arbitration wherever the same or any part of it shall be
      conducted.

26.3  Subject always to Sub-Clause 26.6 below, if any tariff customer (as
      defined in Section 22(4) of the Electricity Act 1989) brings any legal
      proceedings in any court (as defined in the Rules of the Supreme Court
      1965 and in the County Courts Act 1984) against one or more persons, any
      of which is a Party to this Agreement (the "Defendant Party"), and the
      Defendant Party, and the Defendant Party wishes to make a Third Party
      Claim (as defined in Sub-Clause 26.5 below) against any other Party to
      this Agreement ("the Other Party") which would but for this Sub-Clause
      have been a dispute or difference referred to arbitration by virtue of
      Sub-Clause 26.1 above which shall not apply and in lieu of arbitration,
      the court in which the legal proceedings have been commenced shall hear
      and completely determine and adjudicate upon the legal proceedings and the
      Third Party Claim not only between the tariff customer and the Defendant
      Party but also between either or both of them and any Other Party whether
      by way of third party


                                       40
<PAGE>
 
      proceedings (pursuant to the Rules of the Supreme Court 1965 or the County
      Court Rules 1881) or otherwise as may be ordered by the court.

26.4  Where a Defendant Party makes a Third Party Claim against any Other Party
      and such Other Party wishes to make a Third Party Claim against a further
      Party the provisions of Sub-Clause 26.3 above shall apply mutatis mutandis
      as if such Party had been the Defendant Party and similarly in relation to
      any such further Party.

26.5  For the purposes of this Clause 26 "Third Party Claim" shall mean:-

      (a)   any claim by a Defendant Party against any other Party (whether or
            not already a party to the legal proceedings) for any contribution
            or indemnity, or

      (b)   any claim by a Defendant Party against such an Other Party for any
            relief or remedy relating to or connected with the subject matter of
            the legal proceedings and substantially the same as some relief or
            remedy claimed by the tariff customer, or

      (c)   any requirement by a Defendant Party that any question or issue
            relating to or connected with the subject matter of the legal
            proceedings should be determined not only as between the tariff
            customer and the Defendant Party but also as between either or both
            of them and an Other Party (whether or not already a party to the
            legal proceedings).

26.6  Sub-Clause 26.3 above shall apply only if at the time the legal
      proceedings are commenced no arbitration has been commenced between the
      Defendant Party and an Other Party raising or involving the same or
      substantially the same issues as would be raised by or involved in the
      Third Party Claim. The tribunal in any arbitration which has been
      commenced prior to the commencement of legal proceedings shall determine
      the question in the event of dispute, whether the issues raised or
      involved are the same or substantially the same.

      all the Parties irrevocably agree that the courts of England are to have
      exclusive jurisdiction to settle any disputes which may arise out of or in
      connection with this Agreement including the Grid Code and any
      Supplemental Agreement and that accordingly any suit, action or proceeding
      (together in this Clause 27 referred to as "Proceedings") arising out of
      or in connection with this Agreement and any Supplemental Agreement may be
      brought in such courts.

27.2  Each Party irrevocably waives any objection which it may have now or
      hereafter to the laying of the venue of any Proceedings in any such court
      as is referred to in this Clause 27 and any claim that any such
      Proceedings have been brought in an inconvenient forum and further
      irrevocably agrees that judgment in any Proceedings brought in the English
      courts shall be conclusive and binding upon such Party and may enforced in
      the courts of any other jurisdiction.

27.3  Each Party which is not incorporated in any part of England and Wales
      agrees that if it does not have, or shall cease to have, a place of
      business in England and Wales it will promptly appoint, and shall at all
      times maintain, a person in England and Wales irrevocably to accept
      service of process on its behalf in any Proceedings in England.

27.4  For the avoidance of doubt nothing contained in Sub-Clause 27.1 to 27.3
      above shall be taken as permitting a Party to commence Proceedings in the
      courts where this Agreement otherwise provides for Proceedings to be
      referred to arbitration.

28.   GOVERNING LAW

     and that First Hydro will contract to perform these on NGC's behalf and
     that NGC and NGH will agree the necessary documentation and/or amendments
     to the agreement referred to in Subclause 6.3 by 7 November 1995 to give
     effect to the above acknowledgement and agreement.

          NGH Second Dividend will be paid outside the existing consortium
          elections made by NGH and each of the RECs;

     Dividend, the NGH Special Dividend, the NGH Second Dividend and the NGH
     Rights Dividend by CHAPS automated transfer to such REC bank account as may
     be notified by the REC in such request.

8.   The Rights Issue

8.1  NGH undertakes to each of the RECs conditionally upon all of the
     resolutions set out in the NGH EGM Notice having been passed (without
     amendment) at the NGH EGM and subject to Sub-clause 22.3:

     (a)  to effect a rights issue on the basis of one new ordinary share of NGH
          for every 19 existing ordinary shares held on 21 November 1995 at
          (pound)2.04 per new share and that of such new ordinary shares to be
          offered to any shareholder, 44.6 per cent. will be NGH Rights Shares
          and 55.4 per cent. will be new ordinary shares which do not carry an
          entitlement to the NGH Rights Dividend ("Ordinary Shares")(save that
          the allocation of Ordinary Shares and NGH Rights Shares amongst the
          RECs shall be as set out in the NGH EGM Notice), in the manner set out
          in the Rights Issue Circular;

     (b)  to post the Rights Issue Circular and the Listing Particulars to each
          of the shareholders of NGH on 22 November 1995;

     (c)  to procure that each REC which complies with its obligations under
          clause 8.3 shall have the interest for which it shall have subscribed
          pursuant to the Rights Issue entered on the register of members of NGH
          on or before 7 December 1995.

8.2  Any changes to the proof of the Rights Issue Circular set out in Schedule
     VIII which are material to the RECs (or any thereof) shall require the
     prior approval of each of the RECs. Any other changes shall require the
     prior approval (not to be unreasonably withheld or delayed) of each of the
     RECs or of Herbert Smith acting on behalf of all the RECs. Subject thereto,
     the final version of the Rights Issue Circular shall be in the form
     approved by the NGH Board.

8.3  Each REC undertakes to NGH and to NGC, conditionally upon receipt by it of
     its entitlement under the NGH Interim Dividend, the NGH Special Dividend
     and the NGH Second Dividend, that it will take up its full entitlement to
     the rights for which it may subscribe under the terms of the Rights Issue
     Circular and will make payment, in cleared funds, to NGH in accordance with
     the procedure set out in the application form attached to the Rights Issue
     Circular on or before 5 December 1995.

8.4  NGH undertakes to NGC to subscribe for new ordinary shares in NGC for a
     subscription price equal to the proceeds of the rights issue contemplated
     in this Clause 8 as soon as practicable following receipt by NGH of the

                                       8
<PAGE>
 
8.5  Each REC shall accept for its own tax purposes that Section 29 of the
     Taxation of Chargeable Gains Act 1992 shall apply on a basis consistent
     with that assumed for the calculation of the NGH Rights Dividend payable to
     each REC.

9.   Application for Listing

9.1  NGH undertakes to each of the RECs, conditionally upon all of the
     resolutions set out in the NGH EGM Notice having been passed (without
     amendment) at the NGH EGM and subject to Sub-clause 22.3:

     (a)  to use all reasonable endeavors to effect the Flotation in accordance
          with the Timetable;

     (b)  to use all reasonable endeavors to publish the Listing Particulars and
          the Summary Particulars on 22 November 1995;

     (c)  that the Listing Particulars will contain a declaration that the
          directors of NGH accept responsibility for the information contained
          in the Listing Particulars and that to the best of their knowledge and
          belief (having taken all reasonable care to ensure that such is the
          case) the information contained in the Listing Particulars is in
          accordance with the facts and does not omit anything likely to effect
          the import of such information.

     (d)  that the Summary Particulars will contain a statement that the
          directors of NGH are satisfied that the Summary Particulars contain a
          fair summary of the key information set out in the Listing
          Particulars; and

     (e)  not, without the prior approval of each of the RECs (which, in the
          case of the description referred to in (ii) below, shall not be
          unreasonably withheld or delayed) to make any material alteration or
          addition to (i) those sections of the Listing Particulars or Summary
          Particulars which repeat or restate information relating to the RECs
          or to the dividend policy or dividend forecasts of NGH which is
          contained in the Announcement or (ii) the description of the prospects
          of NGH and its subsidiaries set out in the proof of the Listing
          Particulars forming Schedule VI.

9.2  NGH additionally undertakes to each of the RECs that it will:

     (a)  notify the REC Review Committee of any other proposed alteration to
          the Listing Particulars or the Summary Particulars which may
          materially affect the content or import of any part of either document
          (other than any such alteration which has been approved under
          Sub-clause 9.1(d));

     (b)  consider any comments made by the REC Review Committee or any REC
          relating to any such proposed alteration; and



                                       9
<PAGE>
 
     (c)  in the event that NGH is required to publish supplementary listing
          particulars, so far as practicable consult with the REC Review
          Committee regarding their contents and consider any comments made by
          it.

9.3  NGC undertakes to provide all reasonable cooperation and assistance to NGH
     in relation to its obligations under Sub-clauses 9.1 and 9.2.

10.  The REC Review Committee.

10.1 The REC Review Committee shall consist of not less than three members, each
     appointed by the unanimous agreement of the RECs. The first members of the
     REC Review Committee shall be B. Townsend (Midlands), E. Anstee (Eastern),
     A. Coleman (Yorkshire) and J. Tebbs (East Midlands).

10.2 A member of the REC Review Committee may be removed from the REC Review
     Committee only upon his resignation, by notice from the REC by which he is
     (or was) employed in the event of such employment terminating or notice of
     termination having been given or by the unanimous agreement of the RECs. In
     such event a new member of the REC Review Committee shall be appointed by
     the unanimous agreement of the RECs. Any changes to the members of the REC
     Review Committee shall be notified to NGH and NGC as soon as practicable
     following such change.

10.3 Comments to be submitted by the REC Review Committee pursuant to Sub-clause
     9.2(b) on any proposed alteration to the Listing Particulars or Summary
     Particulars or pursuant to Sub-clause 9.2(c) on any supplementary listing
     particulars shall be signed by or on behalf of a majority of the members of
     the REC Review Committee and shall be returned to NGH within 2 business
     days of notification to Kleinwort Benson of the relevant proposals or, if
     earlier, prior to the deadline for printing the relevant document. If no
     comments have been given within the applicable time limit, NGH can proceed
     as though the relevant document was approved by the REC Review Committee
     without comment.

11.  Publication of REC Circulars

11.1 Each Distributing REC undertakes to each of the other RECs and to NGH and
     NGC conditionally upon:

         (i)   the passing of all the resolutions set out in the NGH EGM Notice
               at the NGH EGM;

         (ii)  the publication by NGH of the Listing Particulars and the Summary
               Particulars as contemplated in Clause 9; and

         (iii) not having been subject to a public takeover which has



                                       10
<PAGE>
 
          (iv) become or been declared wholly unconditional prior to the date on
               which it would otherwise have posted its REC Circular in
               accordance with this Agreement;

     (a)  to post its REC Circular to its shareholders on 22 November 1995; and

     (b)  to convene an extraordinary general meeting for 10 a.m. on 8 December
          1995.

11.2 Each Distributing REC undertakes to NGH and NGC that the resolution shall
     be in substantially the form set out in Schedule XI provided that the
     proportion of 25 per cent. in paragraph (i) thereof shall be reduced to
     such lower percentage as may be agreed by NGH with the London Stock
     Exchange as permissible in the context of the Flotation. The final form of
     each such resolution shall be approved by the Board of the relevant
     Distributing REC.

11.3 Each Distributing REC confirms that its board of directors has resolved or
     will resolve (conditionally upon there having been no relevant material
     change of circumstances between the date hereof and the date of publication
     of the REC Circular) to recommend its shareholders to vote in favour of the
     resolution to be proposed at such extraordinary general meeting and that
     the REC Circular will contain a statement to this effect.

11.4 Each Distributing REC shall give NGC the opportunity to review prior to
     dispatch those sections of its Circular which contain information relating
     to NGH, NGC or the Flotation and will consider any comments made thereon by
     NGC.

11.5 If a REC which is not a Distributing REC (and which does not fall within
     Sub-clause 11.1(iii) above) determines to declare and pay a specie dividend
     of some or all of its holding of shares in NGH to be effective on
     Flotation, the provisions of Sub-clauses 11.2 and 11.4 shall apply as it
     were named in this Agreement as a Distributing REC. For the avoidance of
     doubt the foregoing provisions of this Sub-Clause 11.5 shall not apply to a
     REC which has been subject to a public takeover which has become or been
     declared wholly unconditional prior to the date of this Agreement.

12.  The Specie Dividends

     Each Distributing REC undertakes to the other parties, conditionally upon
     the resolution to be proposed at its extraordinary general meeting having
     been passed and having become unconditional in accordance with its terms,
     that it will declare and pay a specie dividend with the effect that not
     less than the proportion of its holding of shares in NGH on Flotation set
     opposite its name in Schedule XIV is distributed to its shareholders.



                                       11
<PAGE>
 
13.  Flotation not effective

     In the event that the Flotation does not become effective before the Long
     Stop Date:

     (a)  NGH undertakes to the RECs to convene an extraordinary general meeting
          to take place within 25 days of the Long Stop Date at which an
          ordinary resolution will be proposed which will provide that the
          directors of NGH shall cease to be its directors and a new NGH Board
          shall be appointed, consisting of 12 persons, each of whom shall have
          been nominated by a different REC; and

     (b)  each of the RECs undertakes to notify NGH within 5 days of the Long
          Stop Date of the identity of the person nominated by it to be a
          director of NGH and to vote in favour of the resolutions referred to
          in Sub-clause 13(a).

14.  Customer Discount

     Subject to Flotation becoming effective and to receipt of its share of the
     NGH Interim Dividend, the NGH Special Dividend, the NGH Second Dividend and
     the NGH Rights Dividend, each of the RECs undertakes to each of the other
     RECs that it will grant the Customer Discount in the manner set out in
     Schedule X; provided that nothing in this Clause 14 shall prevent a REC
     from granting the Customer Discount to customers who are not Eligible
     Customers (as defined in Schedule X) as well as to Eligible Customers. If
     Flotation has not become effective by 31st December 1995, the Record Date
     for the purposes of Schedule X shall be 4 February 1996.

15.  Other undertakings by the RECs

15.1 Each of the RECs undertakes to NGH that, save for any permitted disposal,
     it has not made any decision to sell all or any part of its holding of
     shares in NGH (where the context so allows, as increased by the matters
     provided for in the NGH EGM Circular and the Rights Issue Circular) on or
     prior to Flotation and that it will not make any such decision prior to
     Flotation (or until the date on which it becomes clear that Flotation
     cannot occur by the Long Stop Date). For the avoidance of doubt, there
     shall be no breach of this undertaking solely by reason of the provisions
     in the NGG Articles to be adopted on Flotation.

15.2 For the purposes of Sub-clause 15.1, a permitted disposal shall be:

     (a)  a dividend in specie of shares in NGH by a REC to its shareholders
          becoming effective on or after Flotation;

     (b)  disposals forming part of arrangements to compensate holders of
          options in the REC for the loss of value consequent upon any such
          dividend in specie as is contemplated in Clause 12;



                                       12
<PAGE>
 
     (c)  the disposal of any aggregated fractional entitlements following any
          such dividend in specie as is contemplated in Clause 12;

     (d)  intra-group transfers or sales (including, without limitation, a
          dividend in specie) on or after Flotation;

     (e)  a disposal by Manweb plc (or any transferee thereof under (d) above)
          pursuant to the undertaking to dispose of such shares given by
          Scottish Power plc to the Secretary of State.

15.3 Each of the RECs confirms to NGH, NGC and to the other RECs that the
     section headed "Intentions of the RECs" in the Announcement contains a
     correct statement of its intentions as at the date of this Agreement with
     regard to its shareholding in NGH.

     Each of the RECs undertakes to inform Kleinwort Benson (on behalf of NGH
     and NGC) as soon as is reasonably practicable of any change in this
     intention prior to the date on which the Flotation becomes effective.

15.4 Each of the RECs and NGH undertake to each other and to NGC that they will
     not withdraw or revoke the existing consortium elections so long as the
     same remain relevant to the payment of dividends by NGH contemplated in
     this Agreement.

16.  Cost Sharing

16.1 Save as otherwise set out in this Agreement

16.2 NGC undertakes to the RECs to pay to Eastern Group plc (on behalf of the
     RECs) or to the adviser concerned the proportion (as set out in column 2 of
     Schedule XIV opposite the name of the relevant adviser set out in column 1
     of that Schedule) of the fees (including disbursements and value added tax)
     of each of the advisers to the RECs whose names are set out in column 1 of
     Schedule XIV arising in relation to, or in preparation for, or in
     contemplation of or incidental to, the Flotation and the matters
     contemplated by this Agreement.

16.3 Eastern Group plc shall provide to NGC copies of the relevant invoices in
     relation to the fees to be shared pursuant to Sub-clause 16.2. NGC's
     obligation to make payments in respect of Ernst & Young's fees is subject
     to having first received evidence reasonably satisfactory to it that such
     costs have been properly incurred.

17.  Waiver

     Each REC hereby releases and discharges each other REC and the directors
     and employees of such RECs from any and all actions, proceedings, claims,
     demands or other liabilities whatsoever in relation to liabilities arising
     in connection with or out of the preparation and approval of the Listing
     Particulars and Summary Particulars.

18.  Announcements

18.1 NGH undertakes to issue an announcement in the form set out in Schedule IX
     as soon as practicable following the signature by all parties of this
     Agreement. NGC shall be entitled to issue an announcement in substantially
     similar terms to comply with its obligations under the rules of the London
     Stock Exchange.

18.2 Each of the Distributing RECs undertakes to NGH and to the other
     Distributing RECs that any announcement it makes following the signature of
     this Agreement shall, insofar as it relates to the Flotation or to the
     other matters provided for in this Agreement, be based on the pro forma REC
     announcement set out in Schedule IX.

18.3 If any Distributing REC intends to make an announcement following the
     signature of this Agreement which, insofar as it relates to NGH, NGC, the
     Flotation or to the other matters provided for in this Agreement, differs
     in any significant respect from such pro forma, or if any REC which is not
     a Distributing REC intends to make such an announcement, it shall consult
     with Kleinwort Benson prior to the making of such announcement.

18.4 Each party will use all reasonable endeavors not to issue any further
     public announcements or other public statement or advertisement prior to
     Flotation which contains information relating to NGH or NGC which is
     material to the Flotation or which may be relevant to effecting Flotation
     within the Timetable without first having consulted Kleinwort Benson.

18.5 In relation to any consultation with Kleinwort Benson pursuant to
     Sub-clauses 18.3 and 18.4, the party obliged to so consult shall, unless it
     shall consider that to do so would put it in breach of any statutory or
     regulatory requirement binding upon it or a member of its parent company's
     group, or in breach of the requirements of the London Stock Exchange or of
     the City Code on Takeovers and Mergers, comply with all reasonable requests
     from Kleinwort Benson in relation to the contents, timing or distribution
     of such announcement, statement or advertisement.

19.  NGC Option Schemes

     NGH undertakes to the RECs that it will seek to agree with the Inland
     Revenue that the Adjustments to be made to subsisting options granted under
     the NGC savings related share option scheme and the NGC executive share
     option scheme will be calculated on the basis set out in Schedule XII. No
     adjustments will be made on terms that would be materially more
     advantageous to the optionholders than the terms contemplated in Schedule
     XII without the prior approval of the NGH Board (if approved prior to the
     NGH EGM) or of the REC Oversight Committee (if approved after the NGH EGM).

20.  Variations

20.1 Save as set out in Sub-clauses 20.2, 20.3 and 20.4, variations to this
     Agreement shall not be effected save by means of an instrument executed on
     behalf of all the parties.

20.2 Alterations to the Timetable may be effected by notice from Kleinwort
     Benson provided that no such alteration has the effect of altering the
     process described in Appendix II of the NGH EGM Circular or of causing the
     Flotation to take place after the Long Stop Date. In the event of any such
     alteration to the Timetable dates specified elsewhere in this Agreement
     shall be deemed to be amended to conform to such alteration.

20.3 Each of the RECs and NGH authorizes Herbert Smith to consent on their
     behalf to minor changes or corrections to any of the documents of which
     drafts or proofs are set out in the Schedules.

20.4 The parties recognize that all cash dividends referred to in this Agreement
     will be declared as an amount per share which will be calculated, so far as
     is practicable, so as to result in the total dividend paid being equal to
     the total amount for such dividend specified in this Agreement. Any minor
     variation between the actual total dividend paid and the total specified in
     this Agreement as a result of rounding or as a result of calculating such
     amount per share shall not constitute a variation of this Agreement for the
     purposes of Sub-clause 20.1.

21.  Good Faith

     Each of the parties undertakes to each of the other parties to act in good
     faith and to take all reasonable steps to ensure a successful Flotation in
     accordance with the Timetable.

22.  Force Majeure

22.1 If at any time prior to the publication of the Listing Particulars, NGC
     becomes aware of any event or change in circumstances (which was not known
     to the NGC Board at the date hereof) which is so significant that it would,
     notwithstanding compliance by NGC with its obligations pursuant to Clause
     21, prevent it from fulfilling or make it unlawful to fulfil any of its
     obligations under this Agreement, it shall forthwith notify the other
     parties of such circumstance. If no variation to this Agreement (having
     regard to Clause 21) is agreed pursuant to Sub-clause 20.1 within 5
     business days of such notification NGC may terminate this Agreement
     (subject to Sub-clause 22.5 by notice to the other parties without further
     liability whatsoever to those parties.

22.2 If at any time prior to the date on which the extraordinary general
     meetings of the Distributing RECs are to be held (as contemplated in
     Sub-clause 11.1(b)) there shall be announced by the Government, Inland
     Revenue, Office of Electricity Regulation or some other competent authority
     an actual or proposed change in the



                                       15
<PAGE>
 
     legislative, regulatory or taxation treatment of the RECs generally (an
     "Adverse Announcement"), which change may result in a significant adverse
     financial consequence for the RECs, RECs together holding a majority in
     number of the NGH shares may terminate this Agreement (subject to
     Sub-clause 22.5) by notice to the other parties within 10 business days of
     the Adverse Announcement without further liability whatsoever to those
     parties. Upon an Adverse Announcement NGC and NGH shall be entitled to
     defer performance of any of their respective obligations under this
     Agreement until they are satisfied that this Agreement will not be
     terminated as a result of such Adverse Announcement.

22.3 The obligations of NGC under Sub-clauses 6 and 7.1 and the obligations of
     NGH under Sub-clauses 6, 7.2, 8.1 and 9.1(a) and (b) (each such obligation
     being "Relevant Obligation") shall be conditional upon each of the RECs
     having complied in all respects material to the Flotation with the
     obligations undertaken by it under this Agreement (insofar as the same fall
     to be performed under the terms of this Agreement prior to the time of
     performance of the Relevant Obligation). If such condition is not fulfilled
     at the time otherwise provided for performance by NGC or NGH of a Relevant
     Obligation, NGC or NGH (as the case may be) shall be entitled without
     prejudice to any other rights it may have whether under this Agreement or
     otherwise to waive the condition or (if such default is capable of
     rectification without having a material adverse effect on the Flotation) to
     require the REC in default to rectify such default and, pending such
     rectification, to defer performance of the Relevant Obligation. If such
     default is not rectified within 3 business days of notification or, if
     earlier, by 21st January, 1996, or if the default is incapable of
     rectification without a material adverse effect on Flotation, NGC or NGH
     (as the case may be) may forthwith terminate this Agreement (subject to
     Sub-clause 22.5) by notice to the other parties without further liability
     whatsoever to those parties.

22.4 In the event that the Agreement is terminated pursuant to Sub-clauses 22.1,
     22.2 or 22.3 the Flotation shall not proceed and the parties shall use all
     reasonable endeavors to agree the form of each announcement to be issued in
     respect of such termination. If the Agreement is terminated pursuant to
     Sub-clause 22.2, NGH undertakes to the RECs to withdraw forthwith any
     application for listing which may have been made.

22.5 The termination of this Agreement under Sub-clauses 22.1, 22.2 or 22.3
     shall be without prejudice to the provisions of Clause 13 (Flotation not
     effective), Clause 16 (Cost Sharing) and Sub-clause 22.4, which shall
     continue to have effect and to any liability for antecedent breaches.

22.6 In Sub-clause 22.1, references to NGC shall include references to NGH with
     effect from the date on which the appointment of the NGC Board to the NGH
     Board becomes effective.

WHEREAS

     Following certain changes made at the NGH EGM to the Articles of
     Association of NGG and, effective upon execution of this Agreement, to the
     board of directors of NGG, the parties have agreed that the relationship
     between RECs (being the principal shareholders of NGG) and NGG should be
     regulated in the period prior to Flotation.

NOW IT IS AGREED as follows:

1.   Definitions and Interpretation

1.1. In this Agreement, unless the context otherwise requires, the following
     words and expressions bear the meanings respectively set out below:

     the "EGMs"                         means the NGH EGM and the passing of the
                                        NGC Written Resolutions

     "NGC"                              means The National Grid Company plc.

     the "Master Agreement"             means the agreement of that name dated
                                        25th October 1995 between each of the 
                                        RECs, NGG and NGC.

     the "REC Oversight Committee"      means the committee established pursuant
                                        to Clause 3.

     the "Relevant Period"              means the period commencing with the
                                        execution of this Agreement and 
                                        terminating upon the earlier of the
                                        Flotation or the Termination Date.

     "Termination Date"                 means the date on which directors of NGC
                                        cease to be directors of NGG and
                                        representatives of the RECs are 
                                        appointed in their place.

1.2. Unless the context otherwise requires:

     (a)  any reference in this Agreement to a Clause, Sub-clause or Schedule is
          to a clause, sub-clause or schedule, as the case may be, of or to this
          Agreement;

     (b)  Capitalized terms which are not defined in Clause 1.1 shall have the
          meanings ascribed to them in the Master Agreement; and

     (c)  the singular shall be deemed to include the plural and vice versa.


                                       3
<PAGE>
 
1.3. The headings in this Agreement are for ease of reference only and shall not
     affect the construction of this Agreement.

2.   The Relevant Period

2.1. Save as set out in Clause 2.2 below, during the Relevant Period:

     (a)  NGG will not engage in any activity outside the ordinary course of its
          business;

     (b)  no material contracts or commitments will be entered into by NGG
          unless such contracts or commitments are conditional on Flotation;

     (c)  NGG shall procure that no matters relating to NGC (or its
          subsidiaries) which prior to the EGMs would have required either
          consultation with or the approval of the NGG Board pursuant to the
          Articles of Association of either NGG pr NGC which were in force prior
          to the EGMs, will be carries out by NGC (or such subsidiaries);

     without the prior approval of the REC Oversight Committee or, in the case
     of matters falling within paragraph (c) above which would have required
     consultation only with the NGG Board, consultation with the REC Oversight
     Committee.

     (i)  The REC Oversight Committee shall not unreasonably delay in giving or
          withholding its approval in any case.

     (ii) In relation to any proposal or matter concerning the carrying on of
          the National Grid Business (as defined in the articles of association
          of NGC in the form in force prior to the EGMs) which requires the
          approval of the REC Oversight Committee, such committee shall not be
          entitled to withhold approval unless it has reasonable grounds for
          believing that implementation is likely adversely to affect the
          financial viability of NGC and/or NGG and if the REC Oversight
          Committee does withhold approval it shall provide NGC and NGG with a
          written statement giving details of the grounds for such belief; and

     (iii) In relation to any business or proposed business of NGC or NGG or any
          subsidiary undertakings, other than National Grid Business, the RED
          Oversight Committee shall be entitled to give or withhold approval to
          such plans in whole or in part on any grounds it shall think fit.

- --------------------------------------------------------------------------------
<PAGE>
 
                                       18

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

     Each Interest Period for a Loan will commence on its Drawdown Date or (in
     the case of a Facility A Loan) the expiry of its preceding Interest Period.

(b)  Subject to the following provisions of this Clause 8, each Interest Period
     will be either an approved duration or an optional duration as so selected
     under paragraph (a) above.

     In this Clause 8:-

     "approved duration" means 1 or 2 weeks or 1, 2, 3 or 6 months; and

     "optional duration" means any other period agreed by the Bank.

(c)  If the Borrower fails to select an Interest Period for an outstanding

     Period will, subject to the other provisions of this Clause 8, be one
     month.

     Date.

8.3  Selection of an optional duration

(a)  If the Borrower selects an Interest Period of an optional duration, it may

     (i)  the Borrower requests an Interest Period of an optional duration; and

     (ii) the Bank notifies the Borrower not later than 10.30 a.m. on the first
          Business Day of that Interest Period that matching deposits are not
          available to it in the London interbank market to fund the Loan for
          that Interest Period,

     the Interest Period for that Loan shall be the alternative period so
     specified or, in the absence of any alternative selection, one month.

8.4  Non-Business Days

     If an Interest Period would otherwise end on a day which is not a Business
     Day, that Interest Period shall instead end on the next Business Day in
     that calendar month (if there is one) or the preceding Business Day (if
     there is not).

8.5  Consolidation and splitting

(a)  Notwithstanding Clause 8.2 (Selection), the first Interest Period for each
     Facility A Loan shall end on the same day as the current Interest Period
     for any other Facility A Loan. On the last day of those Interest Periods,
     those Loans shall be consolidated and treated as one Loan.

     treated for all purposes under this Agreement as) two Facility A Loans in
     such amount each

<PAGE>
 
                                       19

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

     being a minimum of (pound)25,000,000 and an integral multiple of
     (pound)1,000,000 as the Borrower shall specify and on the first day of the
     Interest Period to which that notice relates those Facility A Loans shall
     be so divided.

8.6  Other adjustments

     The Bank and the Borrower may enter into such other arrangements as they
     may agree for the adjustment of Interest Periods and the consolidation
     and/or splitting of Loans.

9.   INTEREST

9.1  Interest rate

     The rate of interest on each Loan for each of its Interest Periods is the
     rate per annum determined by the Bank to be the aggregate of the
     applicable:-

     (a)  Margin;

     (b)  LIBOR; and

     (c)  MLA Cost.

9.2  Due dates

     Except as otherwise provided in this Agreement, accrued interest on each
     Loan is payable by the Borrower on the last day of each Interest Period for
     that Loan and also, if the Interest Period is longer than 6 months, on the
     date falling 6 months after the first day of that Interest Period.

9.3  Default interest

(a)  If the Borrower fails to pay any amount payable by it under this Agreement,
     it shall forthwith on demand by the Bank pay interest on the overdue amount
     from the due date up to the date of actual payment, as well after as before
     judgment, at a rate (the "default rate") determined by the Bank to be 1 per
     cent. per annum above the rate which would have been payable if the overdue
     amount had, during the period of non-payment, constituted a Loan in the
     currency of the overdue amount for such successive Interest Periods of such
     duration as the Bank may determine (each a "Designated Interest Period").

(b)  The default rate will be determined by the Bank on each Business Day or the
     first day of, or two Business Days before the first day of, the relevant
     Designated Interest Period, as appropriate.

(c)  If deposits in the currency of the overdue amount are not at the relevant
     time being made available by the Bank to leading banks in the London
     interbank market, the default rate will be determined by reference to the
     cost of funds to the Bank from whatever sources it may select.

(d)  Default interest will be compounded at the end of each Designated Interest
     Period.

     the original due date.

11.  TAXES

11.1 Gross-up

     Subject to Clause 11.4 (Exceptions from gross-up), each payment to be made
     by the Borrower under this Agreement shall be made free and clear of and
     without deduction or withholding (whether for or on account of tax or
     otherwise) unless the Borrower is required by law to make such a payment
     subject to such deduction or withholding in respect of any taxes imposed by
     laws of the United Kingdom or any federation or association of sovereign
     states of which the United Kingdom is a member, in which case the sum
     payable by the Borrower in respect of which such deduction or withholding
     is required to be made shall (subject as provided in this Clause) be
     increased to the extent necessary to ensure that, after the making of such
     deduction or withholding, the Bank receives and retains (free from any
     liability in respect of any such deduction or withholding) a net sum equal
     to the sum which it would have received and so retained had no such
     deduction or withholding been made or required to be made.

                                       21

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

11.2 Tax receipts

     Within 30 days after paying any sum from which it is required by law to
     make any deduction or withholding, the Borrower shall deliver to the Bank
     evidence satisfactory to the Bank of that deduction, withholding or payment
     and (where remittance is required) of the remittance thereof to the
     relevant taxing or other authority (a receipt by the relevant taxing or
     other authority being deemed to be such evidence).

11.3 Tax credits

     If the Borrower makes a payment under Clause 11.1 (Gross-up) for the
     account of the Bank and the Bank determines that it has received or been
     granted a credit against or relief or remission for, or repayment of, any
     tax paid or payable by it in respect of or calculated with reference to the
     deduction or withholding under Clause 11.1 (Gross-up) the Bank shall, to
     the extent that it can do so without prejudice to the retention of the
     amount of such credit, relief, remission or repayment, pay to the Borrower
     such amount as the Bank determines is attributable to such deduction or
     withholding under Clause 11.1 (Gross-up) and which will leave the Bank
     (after such payment) in no better or worse position than it would have been
     in if the Borrower had not been required to make such deduction or
     withholding under Clause 11.1 (Gross-up). Nothing in this Clause 11.3 shall
     interfere with the right of the Bank to arrange its tax affairs in whatever
     manner it thinks fit nor oblige the Bank to disclose any information
     relating to its tax affairs or any computations in respect thereof.

11.4 Exceptions from gross-up

(a)  If:

     (i)  the Bank is not or ceases to be a Qualifying Bank; and

     (ii) as a result the Borrower is required to deduct or withhold United
          Kingdom income tax in respect of payments of interest to be made by
          the Borrower to the Bank under this Agreement,

     then the Borrower shall not be liable to pay under Clause 11.1 (Gross-up)
     in respect of any such payment of interest any amount in excess of the
     amount it would have been obliged to pay if the Bank were a Qualifying Bank
     provided that this Clause 11.4 shall not apply if, after the date of this
     Agreement any change occurs in, or in the official interpretation or
     application of, any relevant law or the practice of the United Kingdom
     Inland Revenue and as a result thereof the Bank is not or ceases to be a
     Qualifying Bank.

(b)  The obligation of the Borrower to pay an additional amount under Clause
     11.1 (Gross-up) shall not apply to the extent that the tax deducted is tax
     on the overall net income of the Bank save to the extent that such tax is
     in respect of the relevant payment from which the deduction must be made.

11.5 Notification

     If at any time after the date of this Agreement the Bank is aware that it
     is not or will cease to be a Qualifying Bank (for whatever reason), it
     shall promptly notify the Borrower.

12.  MARKET DISRUPTION

12.1 Market disruption

     If, by reason of circumstances affecting the London interbank market
     generally, the Bank is unable to make any determination of LIBOR, the Bank
     shall promptly notify the Borrower of the fact and that this Clause 12
     (Market disruption) is in operation.

12.2 Alternative basis

     which has not been made:

     (i)  that Loan shall still be made;

     (iii) interest in respect of that Loan shall be calculated in accordance
          with paragraph (b) below.

(b)  If a notification under Clause 12.1 (Market disruption) applies to a Loan
     then, notwithstanding any other provision of this Agreement:

     (i)  within 5 Business Days of receipt of the notification, the Borrower
          and the Bank shall enter into negotiations for a period of not more
          than 30 days with a view to agreeing an alternative basis for
          determining the rate of interest and/or funding applicable to that
          Loan and/or any other Loans;

     (ii) if no alternative basis is agreed, the Bank shall certify on or before
          the last day of the Interest Period to which the notification relates
          an alternative basis for maintaining that Loan, which shall be binding
          on the Borrower; and

     (iii) any such alternative basis may include an alternative method of
          fixing the interest rate, alternative Interest Periods or alternative
          currencies but it must reflect the cost to the Bank of funding the
          Loan from whatever sources it may select plus the Margin plus any MLA
          Cost.

(c)  The Bank shall consult with the Borrower at least once every 14 days after
     the occurrence and during the continuance of the circumstances specified in
     the foregoing provisions of this Clause 12 with a view to reverting to the
     normal provisions for the determination of the rates of interest applicable
     to any Loan under this Agreement.

13.  INCREASED COSTS

13.1 Increased costs

(a)  Subject to Clause 13.2 (Exceptions), the Borrower shall within 5 Business
     Days of a demand by the Bank pay to the Bank the amount of any increased
     cost incurred by it as a result of any change in or change in the
     interpretation or application of any law or regulation (including any law
     or regulation relating to taxation, or reserve asset, special deposit, cash
     ratio, liquidity or capital adequacy requirements or any other form of
     banking or monetary

     control). Any such demand shall set out in reasonable detail the
     calculation and the cause of the amounts claimed and contain confirmation
     that the Bank is taking the same approach in relation to the majority of
     its other facilities of a similar nature.

(b)  In this Agreement "increased cost" means:

     (i)  an additional cost incurred by the Bank as a result of it having
          entered into, or performing, maintaining or funding its obligations
          under, this Agreement; or

     (ii) that portion of an additional cost incurred by the Bank in making,
          funding or maintaining all or any advances comprised in a class of
          advances formed by or including the Loans made or to be made under
          this Agreement as is attributable to it making, funding or maintaining
          the Loans; or

     (iii) a reduction in any amount payable to the Bank or the effective return
          to the Bank under this Agreement or on its capital; or

     (iv) the amount of any payment made by the Bank, or the amount of any
          interest or other return foregone by the Bank, calculated by reference
          to any amount received or receivable by the Bank under this Agreement.

     (a)  compensated for by the payment of the MLA Cost;

     (b)  compensated for by the operation of Clause 11 (Taxes) or which would
          have been compensated under that Clause but for the operation of
          Clause 11.4 (Exceptions from gross-up);

     (c)  attributable to any change in the rate of tax on the overall net
          income of the Bank;

     (d)  occurring as a result of any negligence or default of the Bank,
          including, without limitation, a breach by the Bank of any fiscal,
          monetary or capital adequacy limit imposed on it by any law or
          regulation; or

     (e)  any increased cost attributable to any implementation of the proposals
          contained in any of:-

               with accrued interest on that portion of the Loan; and

          (ii) the undrawn Commitments shall be reduced to such amount as would
               be lawful or (if no such amount would be lawful) to zero,

     effect.

21.  INDEMNITIES

21.1 Currency indemnity

(a)  If the Bank receives an amount in respect of the Borrower's liability under
     the Finance Documents or if that liability is converted into a claim,
     proof, judgment or order in a currency other than the currency (the
     "contractual currency") in which the amount is expressed to be payable
     under the relevant Finance Document:

     (i)  the Borrower shall indemnify the Bank as an independent obligation
          against any loss or liability arising out of or as a result of the
          conversion;

     (ii) if the amount received by the Bank, when converted into the
          contractual currency at a market rate in the usual course of its
          business is less than the amount owed in the contractual currency, the
          Borrower shall forthwith on demand pay to the Bank an amount in the
          contractual currency equal to the deficit; and

    (iii) the Borrower shall pay to the Bank forthwith on demand any exchange
          costs and taxes payable in connection with any such conversion.

(b)  The Borrower waives any right it may have in any jurisdiction to pay any
     amount under the Finance Documents in a currency other than that in which
     it is expressed to be payable.

21.2 Other indemnities

(a)  The Borrower shall within 10 Business Days of a demand pay to the Bank the
     amount of any loss or liability which the Bank incurs as a consequence of:

     (i)  the occurrence of any Default;

     (ii) the operation of Clause 17.15 (Acceleration); or

    (iii) (other than by reason of negligence or default by the Bank) a Loan
          not being made after the Borrower has delivered a Request or a Loan
          (or part of a Loan) not being prepaid in accordance with a notice of
          prepayment.

     The Borrower's liability in each case includes any loss or expense on
     account of funds borrowed, contracted for or utilised to fund any amount
     payable under any Finance Document, any amount repaid or prepaid or any
     Loan but excludes any loss of margin.

(b)  If the Bank receives or recovers any payment of principal of a Loan or of
     an overdue amount other than on the last day of the Interest Period
     relative to that Loan or amount so received or recovered, the Bank shall
     calculate the difference between:

     (i)  the additional interest (excluding the Margin and MLA Costs) which
          would have been payable on the principal so received or recovered had
          it been received or recovered on the last day of the relevant Interest
          Period; and

     (ii) the amount of interest which would have been payable to the Bank on
          the last day of that Interest Period in respect of the principal so
          received or recovered if the principal so received or recovered had
          been placed on deposit by the Bank earning

                                       38

          interest at the Applicable Rate from (and including) the Business Day
          of receipt of that amount up to (but excluding) the last day of
          applicable Interest Period.

     If (i) is greater than (ii) then the Borrower shall, within five Business
     Days of a demand from the Bank, pay to the Bank an amount equal to the
     difference.

22.  EVIDENCE AND CALCULATIONS

22.1 Accounts

     Accounts maintained by the Bank in connection with this Agreement are prima
     facie evidence of the matters to which they relate.

22.2 Certificates and determinations

     Any certification or determination by the Bank of a rate or amount under
     this Agreement is prima facie evidence of the matters to which it relates.

22.3 Calculations

     Interest (including any applicable MLA Cost) and the fee payable under
     Clause 18.2 (Commitment fee) accrue from day to day and are calculated on
     the basis of the actual number of days elapsed and a year of 365 days.

23.  WAIVERS AND REMEDIES CUMULATIVE

     The rights of the Bank under the Finance Documents:

     (a)  may be exercised as often as necessary;

          and

     (c)  may be waived only in writing and specifically.

     Delay in exercising or non-exercise of any such right is not a waiver of
     that right.

24.  CHANGES TO THE PARTIES

24.1 Transfers by the Borrower

     The Borrower may not assign, transfer, novate or dispose of any of, or any
     interest in, its rights and/or obligations under this Agreement.

24.2 Transfers by the Bank

(a)  The Bank may at any time assign or transfer any of its rights and/or
     obligations under this Agreement to another bank or financial institution
     (the "New Bank"). The prior consent of the Borrower is required for any
     such assignment or transfer and for any sub-participation of the Borrower's
     obligations under this Agreement.

                                       39

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

(b)  A transfer of obligations will be effective only if the New Bank confirms
     to the Borrower that it undertakes to be bound by the terms of this
     Agreement as the Bank in form and substance satisfactory to the Borrower.
     On the transfer becoming effective in this manner the Bank shall be
     relieved of its obligations under this Agreement to the extent that they
     are transferred to the New Bank.

(c)  Subject to paragraph (a), nothing in this Agreement restricts the ability
     of the Bank to sub-contract an obligation if it remains liable under this
     Agreement for that obligation.

25.  DISCLOSURE OF INFORMATION

     Any information supplied to the Bank pursuant to or in connection with this
     Agreement shall be held in confidence and shall not be disclosed by it to
     any person without the prior written consent of the Borrower except to its
     legal or other professional advisers to the extent required for the
     purposes of protecting its rights hereunder or by law or regulation or
     pursuant to applicable reporting requirements or any order of any court or
     to bank supervisory authorities or examining authorities unless it is or
     becomes a matter of public knowledge otherwise than as a result of a breach
     by it of its obligations hereunder.

26.  SET-OFF

     The Bank may set off any matured obligation owed by the Borrower under this
     Agreement (to the extent beneficially owned by the Bank) against any
     matured obligation owed by the Bank to the Borrower, regardless of the
     place of payment, booking branch or currency of either obligation. If the
     obligations are in different currencies, the Bank may convert either
     obligation at a market rate of exchange in its usual course of business for
     the purpose of the set-off.

27.  SEVERABILITY

     If a provision of any Finance Document is or becomes illegal, invalid or
     unenforceable in any jurisdiction, that shall not affect:

     (a)  the validity or enforceability in that jurisdiction of any other
          provision of the Finance Documents; or

     (b)  the validity or enforceability in other jurisdictions of that or any
          other provision of the Finance Documents.

                                   SCHEDULE 2

                           CALCULATION OF THE MLA COST


(a)  The MLA Cost for a Loan for each of its Interest Periods is calculated in
     accordance with the following formula:

     BY+L(Y-X)+S(Y-Z)
     ---------------- % per annum = MLA Cost
        100-(B+S)

     where on the day of application of the formula:

     B    is the percentage of the Bank's eligible liabilities which the Bank of
          England requires the Bank to hold on a non-interest-bearing deposit
          account in accordance with its cash ratio requirements;

     Y    is the rate at which sterling deposits are offered by the Bank to
          leading banks in the London interbank market at or about 11.00 a.m. on
          that day for the relevant period;

     L    is the percentage of eligible liabilities which the Bank of England
          requires the Bank to maintain as secured money with members of the
          London Discount Market Association and/or as secured call money with
          certain money brokers and gilt-edged primary market makers;

     X    is the rate at which secured sterling deposits may be placed by the
          Bank with members of the London Discount Market Association and/or as
          secured call money with certain money brokers and gilt-edged primary
          market makers at or about 11.00 a.m. on that day for the relevant
          period;

     S    is the percentage of the Bank's eligible liabilities which the Bank of
          England requires the Bank to place as a special deposit; and

     Z    is the interest rate per annum allowed by the Bank of England on
          special deposits.

(b)  For the purposes of this Schedule 3:

     (i)  "eligible liabilities" and "special deposits" have the meanings given
          to them at the time of application of the formula by the Bank of
          England; and

     (ii) "relevant period" in relation to each Interest Period, means:

          (A)  if it is 3 months or less, that Interest Period; or

          (B)  if it is more than 3 months, each successive period of 3 months
               and any necessary shorter period comprised in that Interest
               Period.

(c)  In the application of the formula, B, Y, L, X, S and Z are included in the
     formula as figures and not as percentages, e.g. if B = 0.5% and Y = 15%, BY
     is calculated as 0.5 x 15.

<PAGE>
 
                                       44

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

(d)  (i) The formula is applied on the first day of each relevant period
     comprised in the relevant Interest Period.

     (ii) Each rate calculated in accordance with the formula is, if necessary,
          rounded upward to four decimal places.

(e)  If the Bank determines that a change in circumstances has rendered, or will
     render, the formula inappropriate, the Bank shall notify the Borrower of
     the manner in which the MLA Cost will subsequently be calculated which
     shall (so far as practicable) leave the Bank and the Borrower in no better
     or worse position than they would have been in if the relevant change in
     circumstances had not occurred. The manner of calculation so notified by
     the Bank shall, in the absence of manifest error, be binding on the
     Borrower.
