(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

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, INCLUDING BY ENTERING STABILIZING BIDS, PURCHASING 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

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, Yorkshire Group 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,

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.

construed in accordance with, the laws of the State of Delaware. The Trust

                                    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".

the same may be amended and supplemented from time to time, among Yorkshire
Finance, Yorkshire Group, The Bank of New York, as Indenture Trustee, principal

Banque Generale du Luxembourg, as paying agent and transfer agent, pursuant to
which the Junior Subordinated Debentures and the Debentures Guarantee will be

Trust Agreement, among AEP Resources, Inc., as depositor, Yorkshire Group, as
holder of the Control Certificate (as defined herein), The Bank of New York
(Delaware), as Delaware Trustee, The Bank of New York, as Property Trustee, the

                              The record date for each Distribution Date (as

                              Securities--Distributions") will be the close of

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 "baa3" 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

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).

                              Group under the Trust Securities Guarantee, but
                              only to the extent of sufficient funds held by
                              the Trust and available therefor. 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 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--

                              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

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

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

  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

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.

  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).

  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, Yorkshire Group 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 Yorkshire Group 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 will issue the Control Certificate to
AEP Resources for a nominal amount. AEP Resources, in turn, will immediately
transfer such Control Certificate to Yorkshire Group. By holding the Control
Certificate, Yorkshire Group generally 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 Yorkshire Group, 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, as well as any other property or assets
held by the Property Trustee pursuant to 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 a portion 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

                     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.

  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

                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
   
  The following discussion should be read in conjunction with the consolidated
and condensed consolidated financial statements and the notes thereto of the
Successor Company and with the consolidated and condensed financial statements

Financial Data" included elsewhere in this Prospectus. The consolidated and
condensed financial statements of the Successor Company and the Predecessor
Company discussed herein are presented in accordance with US GAAP.     
 
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

  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.

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.

                         Each REC has a substantially regulated
                         monopoly for distribution of electricity in
                         its franchise area. Accordingly, a REC is 
                         the exclusive distributor of electricity
                         within its franchise area regardless of
                         the identity of the generator or supplier
                         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
                         supplier. However, the local REC will still
                         distribute their electricity.

                         Currently, they can purchase their electricity
                         from any licensed supplier although it is
                         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.

  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
   
  Yorkshire Group 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 Yorkshire Group 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 Yorkshire Group, 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 Yorkshire Group, directly or indirectly, a
control certificate (or similar instrument) or common securities relating to
such successor entity, (iii) Yorkshire Group 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, Yorkshire Group 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,
Yorkshire Group, 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 as a trust which does not fall within the provisions of Section 60 UK
Taxation of Chargeable Gains Act of 1992 ("Section 60"), in either case, for
purposes of UK tax law, (iii) Yorkshire Group, 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, Yorkshire Group, as holder of the Control Certificate, 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 fall within the provisions of Section 60 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     
 
                                      80
<PAGE>
 
   
for US Federal income tax purposes, (B) affect 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 does not
fall within the provisions of Section 60, 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
does not fall within the provisions of Section 60, 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
fall within the provisions of Section 60 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.

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, Yorkshire Group 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 Yorkshire
Group, as holder of the Control Certificate. 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.

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 Yorkshire
Group, 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 trust falling
within the provisions of Section 60 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, Yorkshire
Group 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, Yorkshire Group 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) retain the Control Certificate,
provided that certain successors which are permitted pursuant to the Indenture
may succeed to the ownership of the Control Certificate, (ii) use its
reasonable efforts, consistent with the terms and provisions of the Trust
Agreement, to cause (a) the Trust to not be classified as anything other than
a grantor trust for US Federal income tax purposes, (b) the Trust to remain a
trust falling within the provisions of Section 60 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 trust falling within the provisions of
Section 60 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

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.
 
                                      99
<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.
 
 
                                      103
<PAGE>
 
                    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
   
  In the opinion of Dewey Ballantine LLP, counsel to Yorkshire Group,
Yorkshire Finance and the Trust ("Tax Counsel"), the following 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 and 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"), Yorkshire Finance believes 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, Yorkshire Finance intends
to take the position, based on the opinion of Tax Counsel, 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

  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

  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.

                                                                      ==========
</TABLE>
 
  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.

                             (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:

          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
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.
 
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

  The tax years since fiscal year 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 the financial position or
results of operations.
 
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):

  The fair value of long-term debt is estimated based on quoted market prices
for the same or similar issues or the current rates offered to the Company for
debt of the same maturities. The fair values of interest rate swap agreements
are estimated by obtaining quotes from brokers.

  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.

  A provision in respect of these property disposals is made only to the extent
that it is probable that a liability will be incurred.     
 
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.

                             (PREDECESSOR COMPANY)
 
          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  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.

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.

    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:

</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):

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.

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.

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.

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.

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

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
consolidation. In the opinion of the management of the Company, the condensed
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
   
  The Predecessor company unaudited condensed financial statements for the
nine month period ended December 31, 1996 are presented for comparison
purposes only. Those financial statements do not reflect any of the effects of
the purchase accounting adjustments and financing transactions described in
Note 3. Those effects

     NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

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 SWAPS     
   
  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.

at the Time of Purchase.

     SECTION 2.  PAYMENT AND DELIVERY.
                 --------------------

     SECTION 4.  CERTAIN COVENANTS OF THE OFFERORS.
                 --------------------------------- 

     In further consideration of the agreements of the Underwriters herein
contained, each of the Offerors covenants and agrees, jointly and severally, as
follows:

     (a)  The Offerors, on or prior to the Time of Purchase, will deliver to the
          Underwriters conformed copies of the Registration Statement as
          originally filed and of all amendments thereto, heretofore or
          hereafter made, including any post-effective amendment (in each case
          including all exhibits filed therewith, and including unsigned copies
          of each consent and certificate included therein or filed as an
          exhibit thereto).  As soon as Yorkshire Group is advised thereof, it
          will advise ML orally (and to confirm such advice in writing) of (i)
          the issuance of any stop order under the Securities Act with respect
          to the Registration Statement, or the institution of any proceedings
          therefor, of which Yorkshire Group shall have received notice, and
          will use its best efforts to prevent the issuance of any such stop
          order and to secure the prompt removal thereof, if issued and (ii) any
          request by the Commission for amendments or supplements to the
          Registration Statement or the Prospectus or for additional information
          relating thereto.  The Offerors will deliver to the Representatives
          sufficient conformed copies of the Registration Statement, the
          Preliminary Prospectus and the Prospectus and of all supplements and
          amendments thereto (in each case without exhibits) for distribution to
          each Underwriter and, from time to time, as many copies of the
          Preliminary Prospectus and the Prospectus and any amendments and
          supplements thereto in forms approved by the Representatives as the
          Underwriters may reasonably request for the purposes contemplated by
          the Securities Act or the Exchange Act.

     (b)  If, during the period (not exceeding nine months) when the delivery of
          a prospectus shall be required by law in connection with the sale of
          any Trust Securities by any Underwriter or dealer, any event relating
          to or affecting any of the Offerors, or of which any of the Offerors
          shall be advised in writing by the Underwriters, shall occur, which in
          the opinion of counsel for any of the Offerors or the Underwriters
          should be set forth 

                                       7
<PAGE>
 
          in a supplement to or an amendment of the Prospectus, in order to make
          the Prospectus not misleading in the light of the circumstances when
          it is delivered, or if for any other reason it shall be necessary
          during such period to amend or supplement the Prospectus in order to
          comply with the Securities Act or the Exchange Act, the Offerors
          forthwith will (i) notify the Underwriters to suspend solicitation of
          offers to purchase or purchases of the Trust Securities and (ii) at
          its expense, make any such filing or prepare and furnish to the
          Underwriters a reasonable number of copies of a supplement or
          supplements or an amendment or amendments to the Prospectus which will
          supplement or amend the Prospectus so that, as supplemented or
          amended, it will not contain any untrue statement of a material fact
          or omit to state any material fact necessary in order to make the
          statements therein, in the light of the circumstances when the
          Prospectus is delivered, not misleading or which will effect any other
          necessary compliance. In case any Underwriter is required to deliver a
          prospectus in connection with the sale of any Trust Securities after
          the expiration of the period specified in the preceding sentence, the
          Offerors, upon the request of such Underwriter, will furnish to such
          Underwriter, at the expense of such Underwriter, a reasonable quantity
          of supplements or amendments to the Prospectus complying with Section
          10(a) of the Securities Act.

     (c)  Yorkshire Group will make generally available to its security holders
          as soon as practicable but not later than 45 days after the close of
          the period covered thereby, an earning statement of Yorkshire Group
          (in form complying with the provisions of Section 11(a) of the
          Securities Act and Rule 158 of the rules and regulations of the
          Commission under the Securities Act) covering a twelve-month period
          beginning not later than the first day of Yorkshire Group's fiscal
          quarter next following the "effective date" (as defined in Rule 158)
          of the Registration Statement.

     (d)  As soon as practicable after the date of this Agreement, and in any
          event within the time prescribed by Rule 424, the Offerors will file
          the Prospectus with the Commission and will advise ML of such filing
          and to confirm such advice in writing.

     (e)  The Offerors will use their best efforts to qualify the Securities
          (and, if necessary, the Debentures Guarantee and the Junior
          Subordinated Debentures) for offer and sale under the securities or
          "blue sky" laws of such jurisdictions as the Underwriters may
          designate within six months after the date hereof and will pay, or
          will reimburse the Underwriters and their counsel for, reasonable
          filing fees and expenses in connection therewith in an amount not
          exceeding $3,500 in the aggregate (including filing fees and expenses
          paid and incurred prior to the date hereof); provided, however, that
          neither the Trust, Yorkshire Finance nor Yorkshire Group shall be
          required to qualify as a foreign corporation or to file a consent to
          service of process or to file annual reports or to comply 

                                       8
<PAGE>
 
          with any other requirements deemed by the Trust, Yorkshire Finance or
          Yorkshire Group to be unduly burdensome.

     (f)  Yorkshire Group or Yorkshire Finance will pay, except as otherwise
          expressly provided herein, for all expenses incidental to the
          performance of its obligations under this Agreement, including (i) the
          preparation of the Registration Statement, the Preliminary Prospectus
          and the Prospectus (and any amendments or supplements thereto), (ii)
          the issuance and delivery of the Securities, the Junior Subordinated
          Debentures, the Debentures Guarantee and the Control Certificate,
          (iii) the fees and disbursements of the Offerors' counsel and
          accountants, (iv) the fees of The Bank of New York, the Delaware
          Trustee and the fees and disbursements of their counsel, (v) the fees
          and expenses in connection with the rating of the Trust Securities by
          securities rating organizations, (vi) the printing and delivery of
          copies of the Registration Statement, the Preliminary Prospectus and
          the Prospectus (including any amendments or supplements thereto),
          (vii) the fees and expenses in connection with the listing of the
          Trust Securities and, if applicable, the Junior Subordinated
          Debentures on the New York Stock Exchange and the Junior Subordinated
          Debentures on the Luxembourg Stock Exchange including the applications
          therefor and (viii) the Offerors' costs and expenses for travel,
          lodging and incidental expenses relating to investor presentations on
          any "road show" undertaken in connection with the marketing of the
          Trust Securities.  It is understood that, except as provided in
          Section 4(e), this Section 4(f), Section 4(g) and Section 6 hereof,
          the Underwriters will pay all of their costs and expenses, fees of
          their counsel, Winthrop, Stimson, Putnam & Roberts, transfer taxes
          payable on resale of any of the Trust Securities by them, and any
          advertising expenses connected with any offers they may make.

     (g)  If the Underwriters shall not take up and pay for the Trust Securities
          due to the failure of the Offerors to comply with any of the
          conditions specified in Section 3 hereof, or, if this Agreement shall
          be terminated in accordance with the provisions of Section 7 or 8
          hereof, Yorkshire Group or Yorkshire Finance will pay the fees and
          disbursements of Winthrop, Stimson, Putnam & Roberts, counsel to the
          Underwriters, and, if the Underwriters shall not take up and pay for
          the Trust Securities due to the failure of the Offerors to comply with
          any of the conditions specified in Section 3 hereof, Yorkshire Group
          or Yorkshire Finance will reimburse the Underwriters for their
          reasonable out-of-pocket expenses, in an aggregate amount not
          exceeding a total of $10,000, incurred in connection with the
          financing contemplated by this Agreement.

     (h)  During the period of 30 days from the date hereof, the Offerors agree
          not to sell, offer to sell, offer to sell, grant any option for the
          sale of, or otherwise dispose of, without the prior written consent of
          the Representatives, any Trust Securities, any security convertible
          into or 

                                       9

          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 this
          Agreement).

     (i)  The Offerors will (1) use their reasonable best efforts to list,
          subject to notice of issuance, the Trust Securities on the New York
          Stock Exchange and to register the Trust Securities under the Exchange
          Act; (2) if the Trust Securities are exchanged for Junior Subordinated
          Debentures, use their reasonable best efforts to list, subject to
          notice of issuance, the Junior Subordinated Debentures on any exchange
          on which the Trust Securities are then listed and to register the
          Junior Subordinated Debentures under the Exchange Act; and (3) use
          their reasonable best efforts to list the Junior Subordinated
          Debentures on the Luxembourg Stock Exchange.

     (j)  At any time prior to completion of the offering of the Trust
          Securities by the Underwriters to purchasers, the Offerors will not
          make any amendment or supplement to the Prospectus of which the
          Underwriters shall not have previously been advised and furnished a
          copy.

     (k)  The Offerors will use their reasonable best efforts to permit the
          Trust Securities to be eligible for clearance and settlement through
          DTC.

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

     The Offerors, jointly and severally, warrant and represent to each of the

          01, and 333-47925-02) in respect of the Securities, the Debentures

          filed with the Commission by the Offerors in accordance with the
          provisions of the Securities Act such registration statement, as
          amended at the time it (or the most recent post-effective amendment
          thereto) became effective (the "Effective Date"), including the
          financial statements, the exhibits thereto and the information deemed
          to be part thereof pursuant to Rule 430A(b) of the rules and
          regulations of the Commission under the Securities Act, being herein
          called the "Registration Statement", the preliminary prospectus
          included in the Registration Statement prior to the Effective Date or
          filed with the Commission pursuant to paragraph (a) of Rule 424 prior
          to the Effective Date or paragraph (b) of Rule 424 after the Effective
          Date being herein called "Preliminary Prospectus", and the prospectus,
          including the price and terms of the offering, the distribution rate,
          maturity date and certain other information filed with the Commission
          in accordance with Rule 430A of the rules and regulations of

          the Commission under the Securities Act, and pursuant to Rule 424, and
          as it may thereafter be amended or supplemented, being herein called
          "Prospectus." The Registration Statement has been declared effective
          by the Commission and no stop order suspending the effectiveness of
          the Registration Statement has been issued and no proceeding for that

          other agreement or instrument to which the Offerors or YEG are a party
          or by which any of them may be bound or to which any of their
          properties or assets may be subject (except for conflicts, breaches or
          defaults which would not, individually or in the aggregate, be
          materially adverse to the Offerors or YEG or materially adverse to the
          transactions contemplated by this Agreement), (B) any existing
          applicable law, rule, regulation, judgment, order or decree of any
          government, governmental instrumentality or court, domestic or
          foreign, or any regulatory body or administrative agency or other
          governmental body having jurisdiction over the Offerors or YEG or any
          of their respective properties or assets (except for conflicts which
          would not, individually or in the aggregate, be materially adverse to
          the Offerors or YEG or materially adverse to the transactions
          contemplated by this Agreement) or (C) the PES License (as defined in
          the Prospectus).

     (r)  No authorization, approval, consent or order of any court or

     (s)  YEG is entitled to the exemption from the 1935 Act, provided by
          Section 33(a) (1) thereof.

     (t)  The consolidated financial statements of Yorkshire Group and its
          consolidated subsidiaries, together with notes thereto, included in
          the Prospectus present fairly the financial position of Yorkshire
          Group and its consolidated subsidiaries at the dates or for the
          periods indicated; said consolidated financial statements have been
          prepared in conformity with United States generally accepted
          accounting principles applied on a consistent basis throughout the
          periods involved.  The selected financial data and the summary
          financial information included in the Preliminary Prospectus and the
          Prospectus present fairly the information shown therein and have been
          compiled on a basis consistent with that of the audited financial
          statements included in the Preliminary Prospectus and the Prospectus.
          The pro forma financial information included in the Preliminary
          Prospectus and the Prospectus is fairly presented and has been
          properly compiled on the bases described therein.

     (u)  Except as set forth in or contemplated by the Prospectus, and except
          as would not, individually or in the aggregate, be materially adverse

          franchises, licenses, permits and other rights to conduct its business
          and operations as now conducted.

     SECTION 6.  INDEMNITY AND CONTRIBUTION.
     ----------  -------------------------- 

     (a) Yorkshire Group and Yorkshire Finance agree, to the extent permitted by
law, to indemnify, jointly and severally, and hold harmless each of the
Underwriters and each person, if any, who controls any such Underwriter within
the meaning of Section 15 of the 1933 Act or Section 20(a) of the Exchange Act,
against any and all losses, claims, damages or liabilities, joint or several, to
which they or any of them may become subject under the Securities Act or
otherwise, and to reimburse the Underwriters and such controlling person or
persons, if any, for any legal or other expenses as incurred by them in
connection with defending any action, insofar as such losses, claims, damages,
liabilities or actions arise out of or are based upon any untrue statement or
alleged untrue statement of a material fact contained in the Registration
Statement, the Preliminary Prospectus or the Prospectus, or if the Offerors
shall furnish or cause to be furnished to the Underwriters any amendments or any
supplements thereto, as they may be so amended or supplemented, or arise out of
or are based upon any omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading, except insofar as such losses, claims, damages, liabilities or
actions arise out of or are based upon any such untrue statement or alleged
untrue statement or omission or alleged omission which was made in the
Registration Statement, the Preliminary Prospectus or the Prospectus as so
amended or supplemented in reliance upon and in conformity with information
furnished in writing by any Underwriter through the Representatives expressly
for use therein and except (i) with respect to information relating to DTC or
its systems or procedures as set forth in the 

                                       16
<PAGE>
 
Registration Statement, the Prospectus or the Preliminary Prospectus under the
captions "Description of the Trust Securities Book- Entry Issuance" and
"Description of the Junior Subordinated Debentures- Form, Book-Entry Procedures
and Transfer" and (ii) with respect to the Form T-1, and except that this
indemnity shall not inure to the benefit of any Underwriter (or of any person
controlling such Underwriter) on account of any losses, claims, damages,
liabilities or actions arising from the sale of the Trust Securities to any
person if a copy of the Prospectus, as the same may then be supplemented or
amended, was not sent or given by or on behalf of such Underwriter to such
person with or prior to the written confirmation of the sale involved and the
omission or alleged omission or untrue statement or alleged untrue statement was
corrected in the Prospectus as supplemented or amended at the time of such
confirmation and the Prospectus, as so amended and supplemented, was timely
delivered to the Underwriters by the Offerors. Each Underwriter agrees within
ten days after the receipt by it of notice of the commencement of any action in
respect to which indemnity from the Offerors on account of its agreement
contained in this Section 6(a) may be sought by it, or by any person controlling
it, to notify the Offerors in writing of the commencement thereof, but the
failure of such Underwriter so to notify the Offerors of any such action shall
not release the Offerors from any liability which it may have to such
Underwriter or to such controlling person otherwise than on account of the
indemnity agreement contained in this Section 6(a). In case any such action
shall be brought against any Underwriter or any such person controlling such
Underwriter and such Underwriter shall notify the Offerors of the commencement
thereof, as above provided, the Offerors shall be entitled to participate in
(and, to the extent that the Offerors shall wish, including the selection of
counsel (which counsel shall be reasonably satisfactory to the Underwriters), to
direct) the defense thereof at their own expense. In case the Offerors elect to
direct such defense and select such counsel ("Offerors' Counsel"), any
Underwriter or any controlling person shall have the right to employ its own
counsel, but, in any such case, the fees and expenses of such counsel shall be
at the expense of such Underwriter or controlling person unless (i) the Offerors
have agreed in writing to pay such fees and expenses or (ii) the named parties
to any such action (including any impleaded parties) include both any
Underwriter or any controlling person and the Offerors, and any Underwriter or
any controlling person shall have been advised by its counsel that a conflict of
interest between the Offerors and any Underwriter or controlling person may
arise (and the Offerors' Counsel shall have concurred in good faith with such
advice) and for this reason it is not desirable for the Offerors' Counsel to
represent both the indemnifying party and the indemnified party (it being
understood, however, that the Offeror shall not, in connection with any one such
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys for any Underwriter or any controlling person (plus any local counsel
retained by any Underwriter or any controlling person in their reasonable
judgment), which firm (or firms) shall be designated in writing by any
Underwriter or any controlling person).

     (b) Each Underwriter agrees, to the extent permitted by law, to indemnify,
hold harmless and reimburse the Offerors, their directors and their officers,
and each person, if any, who controls the Offerors within the meaning of Section
15 of the 1933 

                                       17
<PAGE>
 
Act or Section 20(a) of the Exchange Act, to the same extent and upon the same
terms as the indemnity agreement of the Offerors set forth in Section 6(a)
hereof, but only with respect to untrue statements or alleged untrue statements
or omissions or alleged omissions made in the Registration Statement, the
Preliminary Prospectus, the Prospectus, as they may be amended or supplemented,
in reliance upon and in conformity with information furnished in writing to the
Offerors by any Underwriter through the Representatives expressly for use
therein. The Offerors agree within ten days after the receipt by it or notice of
the commencement of any action in respect to which indemnity from any
Underwriter on account of its agreement contained in this Section 6(b) may be
sought by it, or by a person controlling it, to notify such Underwriter in
writing of the commencement thereof, but failure of an Offeror so to notify the
Underwriter of any such action shall not release such Underwriter from any
liability which it may have to an Offeror or to such controlling person
otherwise than on account of the indemnity agreement contained in this Section
6(b).

     (c) If recovery is not available under Section 6(a) or 6(b) hereof for any
reason other than as specified therein, the indemnified party shall be entitled
to contribution for any and all losses, claims, damages, liabilities and
expenses for which such indemnification is so unavailable under this Section
6(c).  In determining the amount of contribution to which such indemnified party
is entitled, there shall be considered the portion of the proceeds of the
offering of the Trust Securities realized, the  relative knowledge and access to
information concerning the matter with respect to which the claim was asserted,
the opportunity to correct and prevent any statement or omission, and any
equitable considerations appropriate under the circumstances.  The Offerors and
the Underwriters agree that it would not be equitable if the amount of such
contribution were determined by pro rata or per capita allocation (even if the
Underwriters were treated as one entity for such purpose) without reference to
the considerations called for in the previous sentence. No Underwriter or any
person controlling such Underwriter shall be obligated to contribute any amount
or amounts hereunder which in the aggregate exceeds the total price of the Trust
Securities purchased by such Underwriter under this Agreement, less the
aggregate amount of any damages which such Underwriter and its controlling
persons have otherwise been required to pay in respect of the same claim or any
substantially similar claim. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. Any Underwriter's obligation to contribute under this Section
6 is in proportion to its purchase obligation and not joint with any other
Underwriter or Underwriters.

     (d) No indemnifying party shall, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any litigation, or any investigation or proceeding by
any governmental agency or body, commenced or threatened, or any claim
whatsoever in respect of which indemnification or contribution could be sought
under this Section 6 (whether or not the indemnified parties are actual or
potential parties thereto), unless such settlement, compromise or consent (i)
includes an unconditional release of each indemnified party from all liability
arising out of such litigation, investigation, proceeding or claim and (ii) 

                                       18
<PAGE>
 
does not include a statement as to or an admission of fault, culpability or a
failure to act by or on behalf of such indemnified party.

     SECTION 7.  DEFAULT OF UNDERWRITERS.
                 ----------------------- 

     If any Underwriter or Underwriters under this Agreement shall fail or
refuse (otherwise than for some reason sufficient to justify, in accordance with
the terms hereof, the cancellation or termination of its obligations hereunder)
to purchase and pay for the number of Trust Securities which it has agreed to
purchase and pay for hereunder, and the aggregate number of Trust Securities
with respect to which such default occurs is not more than one-tenth of the
aggregate number of the Trust Securities, the other Underwriters shall be
obligated severally in the proportions which the amounts of Trust Securities set
forth opposite their names in Schedule I hereto bear to the aggregate number of
Trust Securities set forth opposite the names of all such non-defaulting
Underwriters, to purchase the Trust Securities which such defaulting Underwriter
or Underwriters agreed but failed or refused to purchase on the terms set forth
herein; provided that in no event shall the number of Trust Securities which any
Underwriter has agreed to purchase pursuant to Section 1 hereof be increased
pursuant to this Section 7 by an amount in excess of one-ninth of such number of
Trust Securities without the written consent of such Underwriter.  If any
Underwriter or Underwriters shall fail or refuse (otherwise than for some reason
sufficient to justify, in accordance with the terms hereof, the cancellation or
termination of its obligations hereunder) to purchase and pay for the number of
Trust Securities which it has agreed to purchase and pay for hereunder, and the
aggregate number of Trust Securities with respect to which such default occurs
is more than one-tenth of the aggregate number of the Trust Securities, then
this Agreement shall terminate.  In the event of any such termination, the
Offerors shall not be under any liability to any Underwriter (except to the
extent, if any, provided in Section 4(e), Section 4(f) and Section 4(g) or
Section 6 hereof), nor shall any Underwriter (other than an Underwriter who
shall have failed or refused to purchase the Trust Securities it has agreed to
purchase and pay for hereunder without some reason sufficient to justify, in
accordance with the terms hereof, its cancellation or termination of its
obligations hereunder) be under any liability to the Offerors or any other
Underwriter.

     Nothing herein contained shall release any defaulting Underwriter from its
liability to the Offerors or any non-defaulting Underwriter for damages
occasioned by its default hereunder.

     SECTION 8.  TERMINATION OF AGREEMENT BY THE
                 --------------------------------
                 UNDERWRITERS.
                 ------------ 

     This Agreement may be terminated at any time prior to the Time of Purchase
by the Representatives if, after the execution and delivery of this Agreement
and prior to the Time of Purchase, in the reasonable judgment of the
Representatives, the Underwriters' ability to market the Trust Securities shall
have been materially adversely affected because:

                                       19
<PAGE>
 
     (i) trading in securities on the New York Stock Exchange shall have been
     generally suspended by the Commission or by the New York Stock Exchange, or

     (ii) any outbreak or material escalation of hostilities or other calamity
     or crisis materially adversely affecting the financial markets of the
     United States of America or the United Kingdom shall have occurred, or

     (iii)  a general banking moratorium shall have been declared by United
     States federal, New York State or United Kingdom authorities, or

     (iv) there shall have been any decrease in the ratings of any of Yorkshire
     Finance's outstanding debt securities by Moody's or S&P or either Moody's
     or S&P shall publicly announce that it has such rating under consideration
     for possible downgrade.

     If the Representatives elect to terminate this Agreement, as provided in
this Section 8, the Representatives will promptly notify the Offerors by
telephone or by telex or facsimile transmission, confirmed in writing.  If this
Agreement shall not be carried out by any Underwriter for any reason permitted
hereunder, or if the sale of the Trust Securities to the Underwriters as herein
contemplated shall not be carried out because the Offerors are not able to
comply with the terms hereof, the Offerors shall not be under any obligation
under this Agreement and shall not be liable to any Underwriter or to any member
of any selling group for the loss of anticipated profits from the transactions
contemplated by this Agreement (except to the extent, if any, provided in
Section 4(e), Section 4(f) and Section 4(g) or Section 6 hereof) and the
Underwriters shall be under no liability to the Offerors nor be under any
liability under this Agreement to one another.

personam, generally and unconditionally with respect to any civil action, suit
or proceeding for themselves and in respect of their properties, assets and
revenues.

     (b) Yorkshire Group and Yorkshire Finance have irrevocably designated,
appointed, and empowered CT Corporation System, located at 1633 Broadway, New
York, New York 10019, as their designee, appointee and agent to receive, accept
and acknowledge for and on their behalf, and their properties, assets and
revenues, service of any and all legal process, summons, notices and documents
which may be served in any action, suit or proceeding brought against Yorkshire
Group or Yorkshire Finance in any United States or state court.  If for any
reason such designee, appointee and agent hereunder shall cease to be available
to act as such, the Yorkshire Group and Yorkshire Finance agree to designate a
new designee, appointee and agent in the Borough of Manhattan, The City of New
York.  Yorkshire Group and Yorkshire Finance further hereby irrevocably consent
and agree to the service of any and all legal process, summons, notices and
documents in any action, suit or proceeding against Yorkshire Group or Yorkshire
Finance by serving a copy thereof upon the relevant agent for service of process
referred to in this Section 13 (whether or not the appointment of such agent
shall for any reason prove to be ineffective or such agent shall accept or
acknowledge such service) or by mailing copies thereof by registered or
certified air mail, postage prepaid, to Yorkshire Group or Yorkshire Finance at
their respective addresses specified in or designated pursuant to this
Agreement. Yorkshire Group and Yorkshire Finance agree that the failure of any
such designee, appointee and agent to give any notice of such service to them
shall not impair or affect in any way the validity of such service or any
judgment rendered in any action or proceeding based thereon.  Nothing herein
shall in 

                                       21
<PAGE>
 
any way be deemed to limit the ability of the Underwriters to serve any such
legal process, summons, notices and documents in any other manner permitted by
applicable law or to obtain jurisdiction over Yorkshire Group or Yorkshire
Finance or bring actions, suits or proceedings against Yorkshire Group or
Yorkshire Finance in such other jurisdictions, and in such manner, as may be
permitted by applicable law. Yorkshire Group and Yorkshire Finance irrevocably
and unconditionally waive, to the fullest extent permitted by law, any objection
which they may now or hereafter have to the laying of venue of any of the
aforesaid actions, suits or proceedings arising out of or in connection with
this Agreement brought in the Supreme Court of New York, New York County or the
United States District Court for the Southern District of New York and any
appellate court from either thereof and hereby further irrevocably and
unconditionally waive and agree not to plead or claim in any such court that any
such action, suit or proceeding brought in any such court has been brought in an
inconvenient forum.

     SECTION 14.  FOREIGN TAXES; WAIVER OF IMMUNITIES;
                  ------------------------------------
                  JUDGMENT CURRENCY.
                  ----------------- 

     (a) All payments by each of Yorkshire Group or Yorkshire Finance to the
Underwriters hereunder shall be made free and clear of, and without deduction or
withholding for or on account of, any and all present and future income, stamp
or other taxes, levies, imposts, duties, charges, fees, deductions or
withholdings, now or hereafter imposed, levied, collected, withheld or assessed
by the United Kingdom or any other jurisdiction in which Yorkshire Group or
Yorkshire Finance have a branch or an office from which payment is made or
deemed to be made, excluding (i) any such tax imposed by reason of any
Underwriter having some connection with any such jurisdiction other than its
participation as an Underwriter hereunder and (ii) any income or franchise tax
on the overall net income of any Underwriter imposed by the United States of
America or by the State of New York or any political subdivision of the United
States of America or of the State of New York or any political subdivision of
the United States of America or of the State of New York (all such non-excluded
taxes, "Foreign Taxes"). If either Yorkshire Group or Yorkshire Finance is
prevented by operation of law or otherwise from paying, causing to be paid or
remitting that portion of amounts payable hereunder represented by Foreign Taxes
withheld or deducted, then amounts payable under this Agreement shall, to the
extent permitted by law, be increased to such amount as is necessary to yield
and remit to such Underwriter an amount that, after deduction of all Foreign
Taxes (including all Foreign Taxes payable on such increased payments), equals
the amount that would have been payable if no Foreign Taxes applied.

     (b) To the extent that Yorkshire Group or Yorkshire Finance may in any
jurisdiction claim for itself or its assets immunity (to the extent such
immunity may now or hereafter exist, whether on the grounds of sovereign
immunity or otherwise) from, suit, execution, attachment (whether in aid of
execution, before judgment or otherwise) or other legal process (whether through
service or notice or otherwise), and to the extent that in any such jurisdiction
there may be attributed to itself or its assets such immunity (whether or not
claimed), Yorkshire Group and Yorkshire Finance irrevocably agree with respect
to any matter arising under the Agreement, for the benefit of the Underwriters,

                                       22
<PAGE>
 
not to claim, and irrevocably waive, such immunity to the full extent permitted
by the laws of such jurisdiction.

     (c) If for the purpose of obtaining judgment in any court it is necessary
to convert a sum due hereunder to the Underwriters from United States dollars
into another currency, Yorkshire Group and Yorkshire Finance have agreed, and
each Underwriter will be deemed to have agreed, to the fullest extent that they
may effectively do so, that the rate of exchange used shall be that at which in
accordance with normal banking procedures such Underwriters could purchase
United States dollars with such other currency in The City of New York on the
business day preceding the day on which final judgment is given.

     (d) The obligations of Yorkshire Group and Yorkshire Finance in respect of
any sum payable by them to the Underwriters shall, notwithstanding any judgment
in a currency (the "judgment currency") other than United States dollars, be
discharged only to the extent that on the business day following receipt by such
Underwriter of any sum, adjudged to be so due in the judgment currency, such
Underwriter may in accordance with normal banking procedures purchase United
States dollars with the judgment currency; if the amount of United States
dollars so purchased is less than the sum originally due to such Underwriter in
the judgment currency (determined in the manner set forth in the preceding
paragraph), the Yorkshire Group and Yorkshire Finance agree, as a separate
obligation and notwithstanding any such judgment, to indemnify such Underwriter
against such loss, and if the amount of the United States dollars so purchased
exceeds the sum originally due to such Underwriter, such Underwriter agrees to
remit to Yorkshire Group and Yorkshire Finance such excess amount.

     SECTION 15.  EXECUTION OF COUNTERPARTS.
                  ------------------------- 

     This Agreement may be executed in several counterparts, each of which shall
be regarded as an original and all of which shall constitute one and the same
document.

     SECTION 16.  SURVIVAL.

     The indemnity and contribution agreements contained in Section 6 hereof,
Section 13 hereof, Section 14 hereof, and all covenants, warranties and
representations contained in this Agreement, shall remain in full force and
effect regardless of any investigation make by or on behalf of any persons, and

     Re:  Yorkshire Capital Trust I
          -------------------------

Ladies and Gentlemen:

     We have acted as special Delaware counsel for Yorkshire Power Group
Limited, a private company with limited liability incorporated under the laws of
England and Wales ("Yorkshire Group"), Yorkshire Power Finance Limited, a
private company with limited liability incorporated under the laws of the Cayman
Islands ("Yorkshire Finance"), and Yorkshire Capital Trust I, a Delaware
business trust (the "Trust"), in connection with the matters set forth herein.
This opinion is being furnished to you pursuant to Section 3(b)(i) of the
Underwriting Agreement, dated ___________, 1998 (the "Underwriting Agreement"),
among Yorkshire Group, Yorkshire Finance, the Trust and you, as Representatives
of the several Underwriters listed in Schedule I thereto.

     For purposes of giving the opinions hereinafter set forth, our examination
of documents has been limited to the examination of originals or copies of the
following:

        (a) The Certificate of Trust of the Trust, dated ____________, 1998 (the
"Certificate"), as filed in the office of the Secretary of State of the State of
Delaware (the "Secretary of State") on _____________, 1998;

        (b) The Trust Agreement of the Trust, dated as of _______________, 1998

named therein;

        (c) The Amended and Restated Trust Agreement, dated as of
_________________, 1998 (including Exhibits A and C thereto) (the "Trust

                                      A-1
<PAGE>
 
therein, Yorkshire Group, as Control Party, and the holders, from time to time,
of undivided beneficial interests in the assets of the Trust;

        (d)  The Underwriting Agreement;

        (e) The Prospectus, dated ________________, 1998 (the "Prospectus"),
relating to the ___% Trust Securities of the Trust representing undivided
beneficial interests in the assets of the Trust (each, a "Trust Security" and
collectively, the "Trust Securities");

        (f) A Certificate of Good Standing for the Trust, dated ___________,
1998, obtained from the Secretary of State;

        (g) The Subordinated Debenture Indenture, dated as of ____________,

_________ 1, 1998 (collectively, the "Indenture"), which includes the guarantee
of the Debentures (as hereinafter defined) by Yorkshire Group (the "Debentures
Guarantee");

        (h) A specimen of the ___% Junior Subordinated Deferrable Interest
Debentures, Series A due ____________, 2038 (the "Debentures") issued pursuant
to the Indenture; and

        (i) The Trust Securities Guarantee Agreement, dated as of ___________ 1,
1998 between Yorkshire Group and The Bank of New York, as trustee (the "Trust
Securities Guarantee Agreement" and, collectively with the Debentures Guarantee,
the "Guarantees").

     Capitalized terms used herein and not otherwise defined are used as defined
in the Trust Agreement.

     For purposes of this opinion, we have not reviewed any documents other than
the documents listed in paragraphs (a) through (i) above.  In particular, we
have not reviewed any document (other than the documents listed in paragraphs
(a) through (i) above) that is referred to in or incorporated by reference into
the documents reviewed by us.  We have assumed that there exists no provision in
any document that we have not reviewed that is inconsistent with the opinions
stated herein.  We have conducted no independent factual investigation of our
own but rather have relied solely upon the foregoing documents, the statements
and information set forth therein and the additional matters recited or assumed
herein, all of which we have assumed to be true, complete and accurate in all
material respects.

     With respect to all documents examined by us, we have assumed (i) the
authenticity of all documents submitted to us as authentic originals, (ii) the
conformity with the originals of all documents submitted to us as copies or
forms, and (iii) the genuineness of all signatures.

                                      A-2
<PAGE>
 
     For purposes of this opinion, we have assumed (i) the Trust Agreement
constitutes the entire agreement among the parties thereto with respect to the
subject matter thereof, including with respect to the creation, operation and
termination of the Trust, and that the Trust Agreement and the Certificate are
in full force and effect and have not been amended, (ii) except to the extent
provided in paragraph 1 below, the due organization or due formation or due
creation, as the case may be, and valid existence in good standing of each party
to the documents examined by us under the laws of the jurisdiction governing its
organization, formation or creation, (iii) the legal capacity of natural persons
who are parties to the documents examined by us, (iv) except to the extent
provided in paragraph 2 below, the power and authority of each of the parties to
the documents examined by us to execute and deliver, and to perform its
obligations under, such documents, (v) except to the extent provided in
paragraphs 4 and 10 below, the due authorization, execution and delivery by all
parties thereto of all documents examined by us, (vi) the receipt by each Person
to whom a Trust Security is to be issued by the Trust (collectively, the "Trust
Security Holders") of a Trust Securities Certificate for such Trust Security and
the payment for the Trust Security acquired by it, in accordance with the Trust
Agreement and as described in the Prospectus, (vii) the issuance and sale of the
Trust Securities to the Trust Security Holders in accordance with the Trust
Agreement and as described in the Prospectus and (viii) that the Trust Yorkshire
Group [the US Affiliates] and Yorkshire Finance derive no income from or
connected with sources within the State of Delaware and have no assets,
activities (other than (i) with respect to the Trust, having a Delaware Trustee
as required by the Business Trust Act (as defined below), (ii) having a
registered agent as required by the General Corporation Law of the State of
Delaware and (iii) the filing of documents and payment of franchise taxes with
the Secretary of State).  We have not participated in the preparation of the
Prospectus.

     This opinion is limited to the laws of the State of Delaware (excluding the
securities laws of the State of Delaware), and we have not considered and
express no opinion on the laws of any other jurisdiction, including federal laws
and rules and regulations relating thereto.  Our opinions are rendered only with
respect to Delaware laws and rules, regulations and orders thereunder that are
currently in effect.

     Based upon the foregoing, and upon our examination of such questions of law
and statutes of the State of Delaware as we have considered necessary or
appropriate, and subject to the assumptions, qualifications, limitations and
exceptions set forth herein, we are of the opinion that:

        1. The Trust has been duly created and is validly existing in good
standing as a business trust under the Delaware Business Trust Act, 12 Del. C.
(S) 3801, et seq. (the "Business Trust Act"), and all filings required under the
laws of the State of Delaware with respect to the creation and valid existence
of the Trust as a business trust have been made.

        2. Under the Business Trust Act and the Trust Agreement, the Trust has
the trust power and authority to (i) own property and conduct its business, all
as described in the Prospectus, (ii) execute and deliver, and to perform its
obligations under, 

                                      A-3
<PAGE>
 
the Underwriting Agreement, (iii) issue, sell and perform its obligations under,
the Trust Securities and the Control Certificate and (iv) perform its
obligations under the Trust Agreement.

        3. The Trust Securities have been duly authorized by the Trust Agreement
and are duly and validly issued and subject to the qualifications set forth in
paragraph 6 below, are fully paid and non-assessable undivided beneficial
interests in the assets of the Trust and are entitled to the benefits of the
Trust Agreement. Under the Business Trust Act and the Trust Agreement, the
issuance of the Trust Securities is not subject to any preemptive or other
similar rights.

        4. Under the Business Trust Act and the Trust Agreement, (i) the
issuance and sale by the Trust of the Trust Securities and the execution and
delivery by the Trust of the Underwriting Agreement, and the performance by the
Trust of its obligations thereunder, have been duly authorized by all necessary
trust action on the part of the Trust and (ii) assuming the due execution and
delivery of the Underwriting Agreement by the Depositor on behalf of the Trust
and of the certificates for the Trust Securities by one or more of the
Administrative Trustees on behalf of the Trust, the Underwriting Agreement and
the Trust Securities have been duly executed and delivered by the Trust.

        5. No authorization, approval, consent or order of any Delaware court or
Delaware governmental authority or Delaware agency is required to be obtained by
the Trust, Yorkshire Group, the US Affiliates or Yorkshire Finance solely as a
result of (i) the issuance and sale of the Trust Securities, (ii) the issuance
and sale of the Debentures and (iii) the issuance and delivery of the Guarantees
and the Control Certificate.

        6. The Trust Security Holders, as beneficial owners of the Trust, will
be entitled to the same limitation of personal liability extended to
stockholders of private corporations for profit organized under the General
Corporation Law of the State of Delaware. We note that the Trust Security
Holders may be obligated, pursuant to the Trust Agreement, to (i) provide
indemnity and/or security in connection with and pay taxes or governmental
charges arising from transfers or exchanges of Trust Securities Certificates and
the issuance of replacement Trust Securities Certificates and (ii) provide
security or indemnity in connection with requests of or directions to the
Property Trustee to exercise its rights and powers under the Trust Agreement.

        7. The Trust Agreement constitutes a valid and binding obligation of AEP
Resources, Yorkshire Group and the Trustees, and is enforceable against AEP
Resources, Yorkshire Group and the Trustees, in accordance with its terms.

        8. The issuance and sale by the Trust of the Trust Securities, the
issuance and delivery by the Trust of the Control Certificate, the execution,
delivery and performance by the Trust of the Underwriting Agreement, the
consummation by the Trust of the transactions contemplated by the Underwriting
Agreement and the Trust Agreement and compliance by the Trust with its
obligations thereunder do not violate 

                                      A-4
<PAGE>
 
(i) any of the provisions of the Certificate or the Trust Agreement or (ii) any
applicable Delaware law or Delaware administrative regulation.

        9.  We have reviewed the statements in the Prospectus under the caption
"Yorkshire Capital Trust I" and, insofar as they contain statements of Delaware
law, such statements are fairly presented.

        10. The Control Certificate has been duly authorized by the Trust
Agreement and has been duly and validly issued pursuant to the terms of the
Trust Agreement.

     The opinion expressed in paragraph 7 above is subject to the effect upon
the Trust Agreement of (i) bankruptcy, insolvency, moratorium, receivership,
reorganization, liquidation, fraudulent conveyance and transfer and other
similar laws relating to or affecting the rights and remedies of creditors
generally, (ii) principles of equity, including applicable law relating to
fiduciary duties (regardless of whether considered and applied in a proceeding
in equity or at law), and (iii) the effect of applicable public policy on the
enforceability of provisions relating to indemnification.

     We consent to your, and the other several Underwriters,  relying as to
matters of Delaware law upon this opinion in connection with the Underwriting
Agreement.  We consent to the law firms of Dewey Ballantine LLP and Winthrop,
Stimson, Putnam & Roberts relying as to matters of Delaware law upon this
opinion in connection with opinions to be rendered by them pursuant to the
Underwriting Agreement.  Except as stated above, without our prior written
consent, this opinion may not be furnished or quoted to, or relied upon by, any
other Person for any purpose.

                              Very truly yours,

                              RICHARDS, LAYTON & FINGER, P.A.

Re:  Yorkshire Capital Trust I

Debenture Indenture dated as of _____________ 1, 1998, among Yorkshire Finance,
Yorkshire Group and The Bank of New York, as trustee (the "Indenture Trustee"),
as supplemented by the First Supplemental Indenture dated as of _______- __,
1998 (collectively, the "Indenture"); (iv) the Agreement as to Expenses and
Liabilities dated as of ________ __, 1998, between AEP Resources and New Century
International, Inc., a Delaware corporation (collectively, the "US Affiliates")
Yorkshire Group's and the Trust (the "Agreement as to Expenses and
Liabilities"); (v) issuance of a guarantee (the "Trust Securities Guarantee") of
the Trust Securities pursuant to a Trust Securities Guarantee Agreement dated as
of _________ 1, 1998 (the "Trust Securities Guarantee Agreement") between

Trustee"); and

                                      B-1
<PAGE>
 
(vi) Yorkshire Group's issuance of a guarantee (the "Debenture Guarantee") of
the Debentures pursuant to the terms of the Indenture. The Trust Securities are
being sold to you today pursuant to the terms of an Underwriting Agreement dated
__________, 1998 (the "Underwriting Agreement"), among Yorkshire Group,
Yorkshire Finance, the Trust and the underwriters named in Schedule I thereto
(the "Underwriters") for whom you are acting as Representatives. This opinion is
being delivered to you as Representatives pursuant to Section 3(c)(ii) thereof.

     All capitalized terms not otherwise defined herein shall have the meanings
set forth in the Underwriting Agreement.

     In rendering the opinions expressed below, we have examined the
Registration Statement and the Prospectus.  In addition, we have examined, and
have relied as to matters of fact upon, the documents delivered to you at the
closing, and we have made such other and further investigations as we deemed
necessary to express the opinions hereinafter set forth.  In such examination,
we have assumed the genuineness of all signatures, the legal capacity of natural
persons, the authenticity of all documents submitted to us as originals, the
conformity to original documents of all documents submitted to us as certified
or photostatic copies, and the authenticity of the originals of such latter
documents.  Based upon the foregoing, and subject to the qualifications and
limitations stated herein, we are of the opinion that:

        1. All orders, consents, or other authorizations or approvals of the
Commission legally required for the issuance and delivery of the Trust
Securities Guarantee and the Debentures Guarantee by Yorkshire Group, the
issuance and sale of the Debentures by Yorkshire Finance, the issuance and sale
of the Trust Securities by the Trust and the issuance and delivery of the
Control Certificate by the Trust under the 1935 Act have been obtained; such
orders are sufficient for the issuance and delivery of the Trust Securities
Guarantee and the Debentures Guarantee by Yorkshire Group, the issuance and sale

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

Ladies and Gentlemen:

(Delaware), a Delaware banking corporation ("BONY (DE)"), in connection with
Yorkshire Capital Trust I, a business trust created under the laws of the State

__________, 1998, as amended and restated by the Amended and Restated Trust
Agreement, dated as of _____________, 1998 among BONY (DE), Yorkshire Power
Group Limited ("Yorkshire Group"), AEP Resources, Inc., the other trustees named
therein and the holders from time to time of the undivided beneficial interests
in the assets of the Trust (the "Trust Agreement").  This opinion is being
delivered to you pursuant to Section 3(c)(vi) of the Underwriting Agreement,
dated _________ __, 1998 (the "Underwriting Agreement"), among you, as the
representatives of the several Underwriters named in Schedule I thereto,

which the 11,000,000 ___% Trust Securities of the Trust will be sold.  All
capitalized terms used herein and not otherwise defined shall have the
respective meanings set forth in the Underwriting Agreement.

     We examined an original or a copy of the Trust Agreement.  We have also
examined originals or copies of such other documents and such corporate records,
certificates and other statements of governmental officials and corporate

appropriate for the purposes of this opinion.  Moreover, as to certain facts
material to the opinions expressed herein, we have relied upon the

                                      F-1

     Based upon the foregoing and upon an examination of such questions of law
as we have deemed necessary or appropriate, and subject to the assumptions,
exceptions and qualifications set forth below, we advise you that, in our
opinion:

     1.  BONY(DE) is duly incorporated and is validly existing in good standing
as a banking corporation with trust powers under the laws of the State of
Delaware and has the corporate power and authority to execute, deliver and
perform its obligations under the Trust Agreement.

     2.  The Trust Agreement has been duly authorized, executed and delivered by
BONY(DE) and constitutes a legal, valid and binding obligation of BONY(DE),
enforceable against BONY(DE), in accordance with its terms.

     3.  The execution and delivery of, and performance of the terms of, the
Trust Agreement by BONY(DE), do not conflict with or constitute a breach of, or
default under, the charter or by-laws of BONY(DE).

     4.  No consent, approval or authorization of, or registration, declaration
or filing with, any court or governmental agency or body having jurisdiction in
the premises is required under Delaware law for the execution, delivery or
performance by BONY(DE) of the Trust Agreement.

     The foregoing opinions are subject to the following exceptions,
qualifications and assumptions:

     (A) We are admitted to practice in the State of Delaware and we do not hold
ourselves out as being experts on the law of any other jurisdiction.  The

federal laws of the United States of America governing the banking and trust
powers of BONY(DE) (except that we express no opinion with respect to (i) state
securities or blue sky laws and (ii) federal securities laws, including, without
limitation, the Securities Act of 1933, the Securities Exchange Act of 1934,
Trust Indenture Act of 1939 and the Investment Company Act of 1940) and we have
not considered and express no opinion on the laws, rules and regulations of any
other jurisdiction.

     (B) The foregoing opinions regarding enforceability are subject to (i)
applicable bankruptcy, insolvency, moratorium, receivership, reorganization,
fraudulent transfer or conveyance and similar laws relating to and affecting the
rights and remedies of creditors generally, (ii) principles of equity
(regardless of whether considered and applied in a proceeding in equity or at
law), and (iii) the effect of federal or state securities laws on the
enforceability of provisions relating to indemnification or contribution.

     (C) We have assumed the due authorization, execution and delivery by each
of the parties thereto, other than BONY(DE), of the Trust Agreement, and that
each of such parties has the full power, authority and legal right to execute,
deliver and perform such document.

                                      F-2

     (D) We have assumed that all signatures (other than those of the Delaware
Trustee) on documents examined by us are genuine, that all documents submitted
to us as originals are authentic, and that all documents submitted to us as
copies or specimens conform with the originals, which facts we have not
independently verified.

     This opinion may be relied upon by you and the other several Underwriters
in connection with the matters set forth herein, and without our prior written
consent, may not be furnished or quoted to, or relied upon by, any other person

                             ___% Trust Securities

Ladies and Gentlemen:

     We have acted as counsel to the Bank of New York (the "Bank") in connection
with (a) the Subordinated Debenture Indenture, dated as of __________ __, 1998
(the "Original Indenture"), among Yorkshire Power Group Limited ("Yorkshire
Group"), Yorkshire Power Finance Limited ("Yorkshire Finance") and the Bank, as
Trustee, (b) the First Supplemental Indenture dated as of __________ __, 1998
(together with the Original Indenture, herein called the "Indenture"), among
Yorkshire Group, Yorkshire Finance and the Bank, as Trustee, (c) the Trust
Securities Guarantee Agreement dated as of __________, 1998 (the "Guarantee
Agreement") between Yorkshire Group and the Bank, as guarantee trustee, (d) the
Amended and Restated Trust Agreement, dated as of __________ __, 1998 (the
"Trust Agreement") among Yorkshire Group, AEP Resources, Inc., the Bank, as
Property Trustee, The Bank of New York (Delaware), as Delaware Trustee, and the
Administrative Trustees named therein and (e) the Deposit Agreement, dated as of
____________, 1998 (the "Deposit Agreement") between Yorkshire Finance and the
Bank, as Book-Entry Depositary.

     In that connection, we have examined originals, or copies certified or
otherwise identified to our satisfaction, of such documents, records and other
instruments as we have deemed necessary or appropriate for the purpose of this
opinion, including copies of the Indenture, the Trust Agreement, the Guarantee
Agreement, the Deposit Agreement and certain resolutions adopted by the Board of
Directors of the Bank.

     Based upon the foregoing, we are of the opinion that:

     i)  the Bank has been duly incorporated and is validly existing as a
banking corporation in good standing under the laws of the State of New York;

                                      G-1
<PAGE>
 
     ii)   the Bank has the corporate trust power and authority to execute,
deliver and perform its duties under the Indenture, the Trust Agreement, the
Deposit Agreement and the Guarantee Agreement, has duly executed and delivered
the Indenture, the Trust Agreement, the Deposit Agreement and the Guarantee
Agreement, and, insofar as the laws governing the trust powers of the Bank are
concerned and assuming due authorization, execution and delivery thereof by the
other parties thereto, each of the Indenture, the Trust Agreement, the Deposit
Agreement and the Guarantee Agreement constitutes a legal, valid and binding
agreement of the Bank, enforceable against the Bank in accordance with its terms
(subject to applicable bankruptcy, insolvency, fraudulent transfer,
reorganization, moratorium or other laws affecting creditors' rights generally
from time to time in effect and subject, as to enforceability, to general
principles of equity, regardless of whether such enforceability is considered in
a proceeding in equity or at law).

     iii)  the execution, delivery and performance by the Bank of the Indenture,
the Trust Agreement, the Deposit Agreement and the Guarantee Agreement do not
conflict with or constitute a breach of the charter or bylaws of the Bank.

     iv)   no approval, authorization or other action by, or filing with, any
governmental authority of the United States of America or the State of New York
having jurisdiction over the trust powers of the Bank is required in connection
with the execution and delivery by the Bank of the Indenture, the Trust
Agreement or the Guarantee Agreement or the performance by the Bank of its
duties thereunder, except such as have been obtained, taken or made.

     We are admitted to practice in the State of New York, and we express no
opinion as to matters governed by any laws other than the laws of the State of
New York and the Federal law of the United States of America.  We are furnishing
this opinion to you solely for your benefit and the benefit of the other several
Underwriters.  This opinion is not to be used, circulated, quoted or otherwise
referred to for any other purpose.

          required to state the age of the person to whom the resolution

          each director for whom he acts as alternate, in addition to his own
          vote if he is also a director, but he shall count as only one for the
          purpose of determining whether a quorum is present. The last sentence
          of each of regulations 88 and 89 of Table A shall not apply.

     (4)  Any person appointed as an alternate director shall vacate his office
          as an alternate director if the director by whom he has been appointed
          ceases to be a director or removes him or on the happening of any

          vacate that office. Regulation 67 of Table A shall not apply.

          exercise any of the powers conferred by the Statutes to make provision

        "share"                     includes a fraction of a share.

        "Special Resolution"        has the same meaning as in the Statute and

                                    time being in force.


        "written" and "in writing"  include all modes of representing or

        vice-versa.

        Words importing the masculine gender only include the feminine gender.

        Words importing persons only include corporations.


2. The business of the Company may be commenced as soon after incorporation as
the Directors shall see fit, notwithstanding that part only of the shares may
have been allotted.


3. The Directors may pay, out of the capital or any other monies of the Company,
all expenses incurred in or about the formation and establishment of the Company
including the expenses of registration.

                             CERTIFICATES FOR SHARES

4. Certificates representing shares of the Company shall be in such form as
shall be determined by the Directors. Such certificates may be under Seal. All
certificates for shares shall be consecutively numbered or otherwise identified
and shall specify the shares to which they relate. The name and address of the
person to whom the shares represented thereby are issued, with the number of
shares and date of issue, shall be entered in the register of Members of the
Company. All certificates surrendered to the Company for transfer shall be
cancelled and no new certificate shall be issued until the former certificate
for a like number of shares shall have been surrendered and cancelled. The
Directors may authorise certificates to be issued with the seal and authorised
signature(s) affixed by some method or system of mechanical process.

5. Notwithstanding Article 4 of these Articles, if a share certificate be
defaced, lost or destroyed, it may be renewed on payment of a fee of one dollar
(US$l.00) or such less sum and on such terms (if any) as to evidence and
indemnity and the payment of the expenses incurred by the Company
<PAGE>
 
                                       3

in investigating evidence, as the Directors may prescribe.

                                 ISSUE OF SHARES

6. Subject to the provisions, if any, in that behalf in the Memorandum of
Association and to any direction that may be given by the Company in general
meeting and without prejudice to any special rights previously conferred on the
holders of existing shares, the Directors may allot, issue, grant options over
or otherwise dispose of shares of the Company (including fractions of a share)
with or without preferred, deferred or other special rights or restrictions,
whether in regard to dividend, voting, return of capital or otherwise and to
such persons, at such times and on such other terms as they think proper. The
Company shall not issue shares in bearer form.

7. The Company shall maintain a register of its Members and every person whose
name is entered as a Member in the register of Members shall be entitled without
payment to receive within two months after allotment or lodgement of transfer
(or within such other period as the conditions of issue shall provide) one
certificate for all his shares or several certificates each for one or more of
his shares upon payment of fifty cents (US$0.50) for every certificate after the
first or such less sum as the Directors shall from time to time determine
provided that in respect of a share or shares held jointly by several persons
the Company shall not be bound to issue more than one certificate and delivery
of a certificate for a share to one of the several joint holders shall be
sufficient delivery to all such holders.

                               TRANSFER OF SHARES

8. The instrument of transfer of any share shall be in writing and shall be
executed by or on behalf of the transferor and the transferor shall be deemed to
remain the holder of a share until the name of the transferee is entered in the
register in respect thereof.

9. The Directors may in their absolute discretion decline to register any
transfer of shares without assigning any reason therefor. If the Directors
refuse to register a transfer they shall notify the transferee within two months
of such refusal.

10. The registration of transfers may be suspended at such time and for such
periods as the Directors may from time to time determine, provided always that
such registration shall not be suspended for more than forty-five days in any
year.

                                REDEEMABLE SHARES

11. (a) Subject to the provisions of the Statute and the Memorandum of
Association, shares may be issued on the terms that they are, or at the option
of the Company or the holder are, to be redeemed on such terms and in such
manner as the Company, before the issue of the shares, may by Special Resolution
determine.

     (b) Subject to the provisions of the Statute and the Memorandum of
Association, the Company may purchase its own shares (including fractions of a
share), including any redeemable
<PAGE>
 
                                       4

shares, provided that the manner of purchase has first been authorised by the
Company in general meeting and may make payment therefor in any manner
authorised by the Statute, including out of capital.


                          VARIATION OF RIGHTS OF SHARES

12. If at any time the share capital of the Company is divided into different
classes of shares, the rights attached to any class (unless otherwise provided
by the terms of issue of the shares of that class) may, whether or not the
Company is being wound-up, be varied with the consent in writing of the holders
of three-fourths of the issued shares of that class, or with the sanction of a
Special Resolution passed at a general meeting of the holders of the shares of
that class.

     The provisions of these Articles relating to general meetings shall apply
to every such general meeting of the holders of one class of shares except that
the necessary quorum shall be one person holding or representing by proxy at
least one-third of the issued shares of the class and that any holder of shares
of the class present in person or by proxy may demand a poll.

13. The rights conferred upon the holders of the shares of any class issued with
preferred or other rights shall not, unless otherwise expressly provided by the
terms of issue of the shares of that class, be deemed to be varied by the
creation or issue of further shares ranking pari passu therewith

                          COMMISSION ON SALE OF SHARES

14. The Company may in so far as the Statute from time to time permits pay a
commission to any person in consideration of his subscribing or agreeing to
subscribe whether absolutely or conditionally for any shares of the Company.
Such commissions may be satisfied by the payment of cash or the lodgement of
fully or partly paid-up shares or partly in one way and partly in the other. The
Company may also on any issue of shares pay such brokerage as may be lawful.

                            NON-RECOGNITION OF TRUSTS

15. No person shall be recognised by the Company as holding any share upon any
trust and the Company shall not be bound by or be compelled in any way to
recognise (even when having notice thereof) any equitable, contingent, future,
or partial interest in any share, or any interest in any fractional part of a
share, or (except only as is otherwise provided by these Articles or the
Statute) any other rights in respect of any share except an absolute right to
the entirety thereof in the registered holder.

                                 LIEN ON SHARES

16. The Company shall have a first and paramount lien and charge on all shares
(whether fully paid-up or not) registered in the name of a Member (whether
solely or jointly with others) for all debts, liabilities or engagements to or
with the Company (whether presently payable or not) by such Member or his
estate, either alone or jointly with any other person, whether a Member or not,
but the Directors may at any time declare any share to be wholly or in part
exempt from the provisions of this Article. The registration of a transfer of
any such share shall operate as a waiver of the Company's lien
<PAGE>
 
                                        5

(if any) thereon. The Company's lien (if any) on a share shall extend to all
dividends or other monies payable in respect thereof.

17. The Company may sell, in such manner as the Directors think fit, any shares
on which the Company has a lien, but no sale shall be made unless a sum in
respect of which the lien exists is presently payable, nor until the expiration
of fourteen days after a notice in writing stating and demanding payment of such
part of the amount in respect of which the lien exists as is presently payable,
has been given to the registered holder or holders for the time being of the
share, or the person, of which the Company has notice, entitled thereto by
reason of his death or bankruptcy.

18. To give effect to any such sale the Directors may authorise some person to
transfer the shares sold to the purchaser thereof. The purchaser shall be
registered as the holder of the shares comprised in any such transfer, and he
shall not be bound to see to the application of the purchase money, nor shall
his title to the shares be affected by any irregularity or invalidity in the
proceedings in reference to the sale

19. The proceeds of such sale shall be received by the Company and applied in
payment of such part of the amount in respect of which the lien exists as is
presently payable and the residue, if any, shall (subject to a like lien for
sums not presently payable as existed upon the shares before the sale) be paid
to the person entitled to the shares at the date of the sale.

                                 CALL ON SHARES

20. (a) The Directors may from time to time make calls upon the Members in
respect of any monies unpaid on their shares (whether on account of the nominal
value of the shares or by way of premium or otherwise) and not by the conditions
of allotment thereof made payable at fixed terms, provided that no call shall be
payable at less than one month from the date fixed for the payment of the last
preceding call, and each Member shall (subject to receiving at least fourteen
days notice specifying the time or times of payment) pay to the Company at the
time or times so specified the amount called on the shares. A call may be
revoked or postponed as the Directors may determine. A call may be made payable
by instalments.

     (b) A call shall be deemed to have been made at the time when the
resolution of the Directors authorising such call was passed.

     (c) The joint holders of a share shall be jointly and severally liable to
pay all calls in respect thereof.

21. If a sum called in respect of a share is not paid before or on a day
appointed for payment thereof, the persons from whom the sum is due shall pay
interest on the sum from the day appointed for payment thereof to the time of
actual payment at such rate not exceeding ten per cent per annum as the
Directors may determine, but the Directors shall be at liberty to waive payment
of such interest either wholly or in part.

22. Any sum which by the terms of issue of a share becomes payable on allotment
or at any fixed date, whether on account of the nominal value of the share or by
way of premium or otherwise,
<PAGE>
 
                                       6

shall for the purposes of these Articles be deemed to be a call duly made,
notified and payable on the date on which by the terms of issue the same becomes
payable, and in the case of non-payment all the relevant provisions of these
Articles as to payment of interest forfeiture or otherwise shall apply as if
such sum had become payable by virtue of a call duly made and notified.

23. The Directors may, on the issue of shares, differentiate between the holders
as to the amount of calls or interest to be paid and the times of payment. 

24. (a) The Directors may, if they think fit, receive from any Member willing to
advance the same, all or any part of the monies uncalled and unpaid upon any
shares held by him, and upon all or any of the monies so advanced may (until the
same would but for such advances, become payable) pay interest at such rate not
exceeding (unless the Company in general meeting shall otherwise direct) seven
per cent per annum, as may be agreed upon between the Directors and the Member
paying such sum in advance.

     (b) No such sum paid in advance of calls shall entitle the Member paying
such sum to any portion of a dividend declared in respect of any period prior to
the date upon which such sum would, but for such payment, become presently
payable.

                              FORFEITURE OF SHARES

25. (a) If a Member fails to pay any call or instalment of a call or to make any
payment required by the terms of issue on the day appointed for payment thereof,
the Directors may, at any time thereafter during such time as any part of the
call, instalment or payment remains unpaid, give notice requiring payment of so
much of the call, instalment or payment as is unpaid, together with any interest
which may have accrued and all expenses that have been incurred by the Company
by reason of such non-payment. Such notice shall name a day (not earlier than
the expiration of fourteen days from the date of giving of the notice) on or
before which the payment required by the notice is to be made, and shall state
that, in the event of non-payment at or before the time appointed the shares in
respect of which such notice was given will be liable to be forfeited.

     (b) If the requirements of any such notice as aforesaid are not complied
with, any share in respect of which the notice has been given may at any time
thereafter, before the payment required by the notice has been made, be
forfeited by a resolution of the Directors to that effect. Such forfeiture shall
include all dividends declared in respect of the forfeited share and not
actually paid before the forfeiture.

     (c) A forfeited share may be sold or otherwise disposed of on such terms
and in such manner as the Directors think fit and at any time before a sale or
disposition the forfeiture may be cancelled on such terms as the Directors think
fit.

26. A person whose shares have been forfeited shall cease to be a Member in
respect of the forfeited shares, but shall, notwithstanding, remain liable to
pay to the Company all monies which, at the date of forfeiture were payable by
him to the Company in respect of the shares together with interest thereon, but
his liability shall cease if and when the Company shall have received payment in
full of all monies whenever payable in respect of the shares.
<PAGE>
 
                                       7

27. A certificate in writing under the hand of one Director or the Secretary of
the Company that a share in the Company has been duly forfeited on a date stated
in the declaration shall be conclusive evidence of the fact therein stated as
against all persons claiming to be entitled to the share. The Company may
receive the consideration given for the share on any sale or disposition thereof
and may execute a transfer of the share in favour of the person to whom the
share is sold or disposed of and he shall thereupon be registered as the holder
of the share and shall not be bound to see to the application of the purchase
money, if any, nor shall his title to the share be affected by any irregularity
or invalidity in the proceedings in reference to the forfeiture, sale or
disposal of the share. 

28. The provisions of these Articles as to forfeiture shall apply in the case of
non-payment of any sum which, by the terms of issue of a share, becomes payable
at a fixed time, whether on account of the nominal value of the share or by way
of premium as if the same had been payable by virtue of a call duly made and
notified.

                     REGISTRATION OF EMPOWERING INSTRUMENTS

29. The Company shall be entitled to charge a fee not exceeding one dollar
(US$l.00) on the registration of every probate, letters of administration,
certificate of death or marriage, power of attorney, notice in lieu of
distringas, or other instrument.

                             TRANSMISSION OF SHARES

30. In case of the death of a Member, the survivor or survivors where the
deceased was a joint holder, and the legal personal representatives of the
deceased where he was a sole holder, shall be the only persons recognised by the
Company as having any title to his interest in the shares, but nothing herein
contained shall release the estate of any such deceased holder from any
liability in respect of any shares which had been held by him solely or jointly
with other persons.

31. (a) Any person becoming entitled to a share in consequence of the death or
bankruptcy or liquidation or dissolution of a Member (or in any other way than
by transfer) may, upon such evidence being produced as may from time to time be
required by the Directors and subject as hereinafter provided, elect either to
be registered himself as holder of the share or to make such transfer of the
share to such other person nominated by him as the deceased or bankrupt person
could have made and to have such person registered as the transferee thereof,
but the Directors shall, in either case, have the same right to decline or
suspend registration as they would have had in the case of a transfer of the
share by that Member before his death or bankruptcy as the case may be.

     (b) If the person so becoming entitled shall elect to be registered himself
as holder he shall deliver or send to the Company a notice in writing signed by
him stating that he so elects.

32. A person becoming entitled to a share by reason of the death or bankruptcy
or liquidation or dissolution of the holder (or in any other case than by
transfer) shall be entitled to the same dividends and other advantages to which
he would be entitled if he were the registered holder of the share, except that
he shall not, before being registered as a Member in respect of the share, be
entitled in respect of it to exercise any right conferred by membership in
relation to meetings of the Company PROVIDED HOWEVER that the Directors may at
any time give notice requiring any such person to elect either to be registered
himself or to transfer the share and if the notice is not complied with within
<PAGE>
 
                                       8

ninety days the Directors may thereafter withhold payment of all dividends,
bonuses or other monies payable in respect of the share until the requirements
of the notice have been complied with.

                AMENDMENT OF MEMORANDUM OF ASSOCIATION, CHANGE OF
              LOCATION OF REGISTERED OFFICE & ALTERATION OF CAPITAL

33. (a) Subject to and in so far as permitted by the provisions of the Statute,
the Company may from time to time by ordinary resolution alter or amend its
Memorandum of Association otherwise than with respect to its name and objects
and may, without restricting the generality of the foregoing:

          (i)  increase the share capital by such sum to be divided into shares
               of such amount or without nominal or par value as the resolution
               shall prescribe and with such rights, priorities and privileges
               annexed thereto, as the Company in general meeting may determine.

          (ii) consolidate and divide all or any of its share capital into
               shares of larger amount than its existing shares;

          (iii) by subdivision of its existing shares or any of them divide the
               whole or any part of its share capital into shares of smaller
               amount than is fixed by the Memorandum of Association or into
               shares without nominal or par value;

          (iv) cancel any shares which at the date of the passing of the
               resolution have not been taken or agreed to be taken by any
               person.

     (b) All new shares created hereunder shall be subject to the same
provisions with reference to the payment of calls, liens, transfer,
transmission, forfeiture and otherwise as the shares in the original share
capital.

     (c) Subject to the provisions of the Statute, the Company may by Special
Resolution change its name or alter its objects.

     (d) Without prejudice to Article 11 hereof and subject to the provisions of
the Statute, the Company may by Special Resolution reduce its share capital and
any capital redemption reserve fund.

     (e) Subject to the provisions of the Statute, the Company may by resolution
of the Directors change the location of its registered office.

                CLOSING REGISTER OF MEMBERS OR FIXING RECORD DATE

34. For the purpose of determining Members entitled to notice of or to vote at
any meeting of Members or any adjournment thereof, or Members entitled to
receive payment of any dividend, or in order to make a determination of Members
for any other proper purpose, the Directors of the Company may provide that the
register of Members shall be closed for transfers for a stated period but not to
exceed in any case forty days. If the register of Members shall be so closed for
the purpose of determining Members entitled to notice of or to vote at a meeting
of Members such register shall be so closed for at least ten days immediately
preceding such meeting and the record date for such
<PAGE>
 
                                       9

determination shall be the date of the closure of the register of Members.

35. In lieu of or apart from closing the register of Members, the Directors may
fix in advance a date as the record date for any such determination of Members
entitled to notice of or to vote at a meeting of the Members and for the purpose
of determining the Members entitled to receive payment of any dividend the
Directors may, at or within 90 days prior to the date of declaration of such
dividend fix a subsequent date as the record date for such determination.

36. If the register of Members is not so closed and no record date is fixed for
the determination of Members entitled to notice of or to vote at a meeting of
Members or Members entitled to receive payment of a dividend, the date on which
notice of the meeting is mailed or the date on which the resolution of the
Directors declaring such dividend is adopted, as the case may be, shall be the
record date for such determination of Members. When a determination of Members
entitled to vote at any meeting of Members has been made as provided in this
section, such determination shall apply to any adjournment thereof.

                                 GENERAL MEETING

37. (a) Subject to paragraph (c) hereof, the Company shall within one year of
its incorporation and in each year of its existence thereafter hold a general
meeting as its annual general meeting and shall specify the meeting as such in
the notices calling it. The annual general meeting shall be held at such time
and place as the Directors shall appoint and if no other time and place is
prescribed by them, it shall be held at the registered office on the second
Wednesday in December of each year at ten o'clock in the morning.

     (b) At these meetings the report of the Directors (if any) shall be
presented.

     (c) If the Company is exempted as defined in the Statute it may but shall
not be obliged to hold an annual general meeting.

38. (a) The Directors may whenever they think fit, and they shall on the
requisition of Members of the Company holding at the date of the deposit of the
requisition not less than one-tenth of such of the paid-up capital of the
Company as at the date of the deposit carries the right of voting at general
meetings of the Company, proceed to convene a general meeting of the Company.

     (b) The requisition must state the objects of the meeting and must be
signed by the requisitionists and deposited at the registered office of the
Company and may consist of several documents in like form each signed by one or
more requisitionists.

     (c) If the Directors do not within twenty-one days from the date of the
deposit of the requisition duly proceed to convene a general meeting, the
requisitionists, or any of them representing more than one-half of the total
voting rights of all of them, may themselves convene a general meeting, but any
meeting so convened shall not be held after the expiration of three months after
the expiration of the said twenty-one days.

     (d) A general meeting convened as aforesaid by requisitionists shall be
convened in the same manner as nearly as possible as that in which general
meetings are to be convened by Directors.

                           NOTICE OF GENERAL MEETINGS

39. At least five days' notice shall be given of an annual general meeting or
any other general meeting. Every notice shall be exclusive of the day on which
it is given or deemed to be given and of the day for which it is given and shall
specify the place, the day and the hour of the meeting and the general nature of
the business and shall be given in manner hereinafter mentioned or in such other
manner if any as may be prescribed by the Company PROVIDED that a general
meeting of the Company shall, whether or not the notice specified in this
regulation has been given and whether or not the provisions of Article 38 have
been complied with, be deemed to have been duly convened if it is so agreed:

     (a)  in the case of a general meeting called as an annual general meeting
          by all the Members entitled to attend and vote thereat or their
          proxies; and

     (b)  in the case of any other general meeting by a majority in number of
          the Members having a right to attend and vote at the meeting, being a
          majority together holding not less than seventy-five per cent in
          nominal value or in the case of shares without nominal or par value
          seventy-five per cent of the shares in issue, or their proxies.

40. The accidental omission to give notice of a general meeting to, or the
non-receipt of notice of a meeting by any person entitled to receive notice
shall not invalidate the proceedings of that meeting.

                         PROCEEDINGS AT GENERAL MEETINGS

41. No business shall be transacted at any general meeting unless a quorum of
Members is present at the time when the meeting proceeds to business; two
Members present in person or by proxy shall be a quorum provided always that if
the Company has one Member of record the quorum shall be that one Member present
in person or by proxy.

42. A resolution (including a Special Resolution) in writing (in one or more
counterparts) signed by all Members for the time being entitled to receive
notice of and to attend and vote at general meetings (or being corporations by
their duly authorised representatives) shall be as valid and effective as if the
same had been passed at a general meeting of the Company duly convened and held.

43. If within half an hour from the time appointed for the meeting a quorum is
not present, the meeting, if convened upon the requisition of Members, shall be
dissolved and in any other case it shall stand adjourned to the same day in the
next week at the same time and place or to such other time or such other place
as the Directors may determine and if at the adjourned meeting a quorum is not
present within half an hour from the time appointed for the meeting the Members
present shall be a quorum.

44. The Chairman, if any, of the Board of Directors shall preside as Chairman at
every general meeting of the Company, or if there is no such Chairman, or if he
shall not be present within fifteen minutes after the time appointed for the
holding of the meeting, or is unwilling to act, the Directors present shall
elect one of their number to be Chairman of the meeting.
<PAGE>
 
                                       11

45. If at any general meeting no Director is willing to act as Chairman or if no
Director is present within fifteen minutes after the time appointed for holding
the meeting, the Members present shall choose one of their number to be Chairman
of the meeting.

46. The Chairman may, with the consent of any general meeting duly constituted
hereunder, and shall if so directed by the meeting, adjourn the meeting from
time to time and from place to place, but no business shall be transacted at any
adjourned meeting other than the business left unfinished at the meeting from
which the adjournment took place. When a general meeting is adjourned for thirty
days or more, notice of the adjourned meeting shall be given as in the case of
an original meeting; save as aforesaid it shall not be necessary to give any
notice of an adjournment or of the business to be transacted at an adjourned
general meeting. 

47. At any general meeting a resolution put to the vote of the meeting shall be
decided on a show of hands unless a poll is, before or on the declaration of the
result of the show of hands, demanded by the Chairman or any other Member
present in person or by proxy.

48. Unless a poll be so demanded a declaration by the Chairman that a resolution
has on a show of hands been carried, or carried unanimously, or by a particular
majority, or lost, and an entry to that effect in the Company's Minute Book
containing the Minutes of the proceedings of the meeting shall be conclusive
evidence of that fact without proof of the number or proportion of the votes
recorded in favour of or against such resolution.

49. The demand for a poll may be withdrawn.

50. Except as provided in Article 52, if a poll is duly demanded it shall be
taken in such manner as the Chairman directs and the result of the poll shall be

demanded.

poll, the Chairman of the general meeting at which the show of hands takes place
or at which the poll is demanded, shall be entitled to a second or casting vote.

52. A poll demanded on the election of a Chairman or on a question of
adjournment shall be taken forthwith. A poll demanded on any other question
shall be taken at such time as the Chairman of the general meeting directs and
any business other than that upon which a poll has been demanded or is
contingent thereon may be proceeded with pending the taking of the poll.

                                VOTES OF MEMBERS

53. Subject to any rights or restrictions for the time being attached to any
class or classes of shares, on a show of hands every Member of record present in
person or by proxy at a general meeting shall have one vote and on a poll every
Member of record present in person or by proxy shall have one vote for each
share registered in his name in the register of Members.

54. In the case of joint holders of record the vote of the senior who tenders a

<PAGE>
 
                                       12

for this purpose seniority shall be determined by the order in which the names
stand in the register of Members.

55. A Member of unsound mind, or in respect of whom an order has been made by
any court, having jurisdiction in lunacy, may vote, whether on a show of hands
or on a poll, by his committee, receiver, curator bonis, or other person in the
nature of a committee, receiver or curator bonis appointed by that court, and
any such committee, receiver, curator bonis or other persons may vote by proxy.

56. No Member shall be entitled to vote at any general meeting unless he is
registered as a shareholder of the Company on the record date for such meeting
nor unless all calls or other sums presently payable by him in respect of shares
in the Company have been paid.

57. No objection shall be raised to the qualification of any voter except at the
general meeting or adjourned general meeting at which the vote objected to is
given or tendered and every vote not disallowed at such general meeting shall be
valid for all purposes. Any such objection made in due time shall be referred to
the Chairman of the general meeting whose decision shall be final and
conclusive.

58. On a poll or on a show of hands votes may be given either personally or by
proxy.

                                     PROXIES

59. The instrument appointing a proxy shall be in writing and shall be executed
under the hand of the appointor or of his attorney duly authorised in writing,
or, if the appointor is a corporation under the hand of an officer or attorney
duly authorised in that behalf. A proxy need not be a Member of the Company.

60. The instrument appointing a proxy shall be deposited at the registered
office of the Company or at such other place as is specified for that purpose in
the notice convening the meeting no later than the time for holding the meeting,
or adjourned meeting provided that the Chairman of the Meeting may at his
discretion direct that an instrument of proxy shall be deemed to have been duly
deposited upon receipt of telex, cable or telecopy confirmation from the
appointor that the instrument of proxy duly signed is in the course of
transmission to the Company.

61. The instrument appointing a proxy may be in any usual or common form and may
be expressed to be for a particular meeting or any adjournment thereof or
generally until revoked. An instrument appointing a proxy shall be deemed to
include the power to demand or join or concur in demanding a poll.

62. A vote given in accordance with the terms of an instrument of proxy shall be
valid notwithstanding the previous death or insanity of the principal or
revocation of the proxy or of the authority under which the proxy was executed,
or the transfer of the share in respect of which the proxy is given provided
that no intimation in writing of such death, insanity, revocation or transfer as
aforesaid shall have been received by the Company at the registered office
before the commencement
<PAGE>
 
                                       13

of the general meeting, or adjourned meeting at which it is sought to use the
proxy.

63. Any corporation which is a Member of record of the Company may in accordance
with its Articles or in the absence of such provision by resolution of its
Directors or other governing body authorise such person as it thinks fit to act
as its representative at any meeting of the Company or of any class of Members
of the Company, and the person so authorised shall be entitled to exercise the
same powers on behalf of the corporation which he represents as the corporation
could exercise if it were an individual Member of record of the Company.

64. Shares of its own capital belonging to the Company or held by it in a
fiduciary capacity shall not be voted, directly or indirectly, at any meeting
and shall not be counted in determining the total number of outstanding shares
at any given time.



                                    DIRECTORS

65. There shall be a Board of Directors consisting of not less than one or more
than ten persons (exclusive of alternate Directors) PROVIDED HOWEVER that the
Company may from time to time by ordinary resolution increase or reduce the
limits in the number of Directors. The first Directors of the Company shall be
determined in writing by, or appointed by a resolution of, the subscribers of
the Memorandum of Association or a majority of them.

66. The remuneration to be paid to the Directors shall be such remuneration as
the Directors shall determine. Such remuneration shall be deemed to accrue from
day to day. The Directors shall also be entitled to be paid their travelling,
hotel and other expenses properly incurred by them in going to, attending and
returning from meetings of the Directors, or any committee of the Directors, or
general meetings of the Company, or otherwise in connection with the business of
the Company, or to receive a fixed allowance in respect thereof as may be
determined by the Directors from time to time, or a combination partly of one
such method and partly the other.

67. The Directors may by resolution award special remuneration to any Director
of the Company undertaking any special work or services for, or undertaking any
special mission on behalf of, the Company other than his ordinary routine work
as a Director. Any fees paid to a Director who is also counsel or solicitor to
the Company, or otherwise serves it in a professional capacity shall be in
addition to his remuneration as a Director.

68. A Director or alternate Director may hold any other office or place of
profit under the Company (other than the office of Auditor) in conjunction with
his office of Director for such period and on such terms as to remuneration and
otherwise as the Directors may determine.

69. A Director or alternate Director may act by himself or his firm in a
professional capacity for the Company and he or his firm shall be entitled to
remuneration for professional services as if he were not a Director or alternate
Director.

70. A shareholding qualification for Directors may be fixed by the Company in
general
<PAGE>
 
                                       14

meeting, but unless and until so fixed no qualification shall be required.

71. A Director or alternate Director of the Company may be or become a director
or other officer of or otherwise interested in any company promoted by the
Company or in which the Company may be interested as shareholder or otherwise
and no such Director or alternate Director shall be accountable to the Company
for any remuneration or other benefits received by him as a director or officer
of, or from his interest in, such other company.

72. No person shall be disqualified from the office of Director or alternate
Director or prevented by such office from contracting with the Company, either
as vendor, purchaser or otherwise, nor shall any such contract or any contract
or transaction entered into by or on behalf of the Company in which any Director
or alternate Director shall be in any way interested be or be liable to be
avoided, nor shall any Director or alternate Director so contracting or being so
interested be liable to account to the Company for any profit realised by any
such contract or transaction by reason of such Director holding office or of the
fiduciary relation thereby established. A Director (or his alternate Director in
his absence) shall be at liberty to vote in respect of any contract or
transaction in which he is so interested as aforesaid PROVIDED HOWEVER that the
nature of the interest of any Director or alternate Director in any such
contract or transaction shall be disclosed by him or the alternate Director
appointed by him at or prior to its consideration and any vote thereon.

73. A general notice that a Director or alternate Director is a shareholder of
any specified firm or company and is to be regarded as interested in any
transaction with such firm or company shall be sufficient disclosure under
Article 72 and after such general notice it shall not be necessary to give
special notice relating to any particular transaction.

                               ALTERNATE DIRECTORS

74. Subject to the exception contained in Article 82, a Director who expects to
be unable to attend Directors' Meetings because of absence, illness or otherwise
may appoint any person to be an alternate Director to act in his stead and such
appointee whilst he holds office as an alternate Director shall, in the event of
absence therefrom of his appointor, be entitled to attend meetings of the
Directors and to vote thereat and to do, in the place and stead of his
appointor, any other act or thing which his appointor is permitted or required
to do by virtue of his being a Director as if the alternate Director were the
appointor, other than appointment of an alternate to himself, and he shall ipso
facto vacate office if and when his appointor ceases to be a Director or removes
the appointee from office. Any appointment or removal under this Article shall
be effected by notice in writing under the hand of the Director making the same.

                         POWERS AND DUTIES OF DIRECTORS

75. The business of the Company shall be managed by the Directors (or a sole
Director if only one is appointed) who may pay all expenses incurred in
promoting, registering and setting up the Company, and may exercise all such
powers of the Company as are not, from time to time by the Statute, or by these
Articles, or such regulations, being not inconsistent with the aforesaid, as may
be prescribed by the Company in general meeting required to be exercised by the
Company in general
<PAGE>
 
                                       15

meeting PROVIDED HOWEVER that no regulations made by the Company in general
meeting shall invalidate any prior act of the Directors which would have been
valid if that regulation had not been made.

76. The Directors may from time to time and at any time by powers of attorney
appoint any company, firm, person or body of persons, whether nominated directly
or indirectly by the Directors, to be the attorney or attorneys of the Company
for such purpose and with such powers, authorities and discretions (not
exceeding those vested in or exercisable by the Directors under these Articles)
and for such period and subject to such conditions as they may think fit, and
any such powers of attorney may contain such provisions for the protection and
convenience of persons dealing with any such attorneys as the Directors may
think fit and may also authorise any such attorney to delegate all or any of the
powers, authorities and discretions vested in him.

77. All cheques, promissory notes, drafts, bills of exchange and other
negotiable instruments and all receipts for monies paid to the Company shall be
signed, drawn, accepted, endorsed or otherwise executed as the case may be in
such manner as the Directors shall from time to time by resolution determine.
78. The Directors shall cause minutes to be made in books provided for the
purpose:

     (a)  of all appointments of officers made by the Directors;

     (b)  of the names of the Directors (including those represented thereat by
          an alternate or by proxy) present at each meeting of the Directors and
          of any committee of the Directors;

     (c)  of all resolutions and proceedings at all meetings of the Company and
          of the Directors and of committees of Directors.

or place of profit with the Company or to his widow or dependants and may make
contributions to any fund and pay premiums for the purchase or provision of any
such gratuity, pension or allowance.

80. The Directors may exercise all the powers of the Company to borrow money and
to mortgage or charge its undertaking, property and uncalled capital or any part
thereof and to issue debentures, debenture stock and other securities whether
outright or as security for any debt, liability or obligation of the Company or
of any third party.

                                   MANAGEMENT

81. (a) The Directors may from time to time provide for the management of the
affairs of the Company in such manner as they shall think fit and the provisions
contained in the three next following paragraphs shall be without prejudice to
the general powers conferred by this paragraph.

     (b) The Directors from time to time and at any time may establish any
committees, local boards or agencies for managing any of the affairs of the
Company and may appoint any persons to be members of such committees or local
boards or any managers or agents and may fix their
<PAGE>
 
                                       16

remuneration.

     (c) The Directors from time to time and at any time may delegate to any
such committee, local board, manager or agent any of the powers, authorities and
discretions for the time being vested in the Directors and may authorise the
members for the time being of any such local board, or any of them to fill up
any vacancies therein and to act notwithstanding vacancies and any such
appointment or delegation may be made on such terms and subject to such
conditions as the Directors may think fit and the Directors may at any time
remove any person so appointed and may annul or vary any such delegation, but no
person dealing in good faith and without notice of any such annulment or
variation shall be affected thereby.

     (d) Any such delegates as aforesaid may be authorised by the Directors to
subdelegate all or any of the powers, authorities, and discretions for the time
being vested in them.

                               MANAGING DIRECTORS

82. The Directors may, from time to time, appoint one or more of their body (but
not an alternate Director) to the office of Managing Director for such term and
at such remuneration (whether by way of salary, or commission, or participation
in profits, or partly in one way and partly in another) as they may think fit
but his appointment shall be subject to determination ipso facto if he ceases
from any cause to be a Director and no alternate Director appointed by him can
act in his stead as a Director or Managing Director.

83. The Directors may entrust to and confer upon a Managing Director any of the
powers exercisable by them upon such terms and conditions and with such
restrictions as they may think fit and either collaterally with or to the

or vary all or any of such powers.

                            PROCEEDINGS OF DIRECTORS

84. Except as otherwise provided by these Articles, the Directors shall meet
together for the despatch of business, convening, adjourning and otherwise
regulating their meetings as they think fit. Questions arising at any meeting
shall be decided by a majority of votes of the Directors and alternate Directors
present at a meeting at which there is a quorum, the vote of an alternate
Director not being counted if his appointor be present at such meeting. In case
of an equality of votes, the Chairman shall have a second or casting vote.

85. A Director or alternate Director may, and the Secretary on the requisition
of a Director or alternate Director shall, at any time summon a meeting of the
Directors by at least two days' notice in writing to every Director and
alternate Director which notice shall set forth the general nature of the
business to be considered unless notice is waived by all the Directors (or their
alternates) either at, before or after the meeting is held and PROVIDED FURTHER
if notice is given in person, by cable, telex or telecopy the same shall be
deemed to have been given on the day it is delivered to the Directors or
transmitting organisation as the case may be. The provisions of Article 40 shall
apply mutatis mutandis with respect to notices of meetings of Directors.
<PAGE>
 
                                       17

86. The quorum necessary for the transaction of the business of the Directors
may be fixed by the Directors and unless so fixed shall be two, a Director and
his appointed alternate Director being considered only one person for this
purpose, PROVIDED ALWAYS that if there shall at any time be only a sole Director
the quorum shall be one. For the purposes of this Article an alternate Director
or proxy appointed by a Director shall be counted in a quorum at a meeting at
which the Director appointing him is not present.

87. The continuing Directors may act notwithstanding any vacancy in their body,
but if and so long as their number is reduced below the number fixed by or
pursuant to these Articles as the necessary quorum of Directors the continuing
Directors or Director may act for the purpose of increasing the number of
Directors to that number, or of summoning a general meeting of the Company, but
for no other purpose.

88. The Directors may elect a Chairman of their Board and determine the period
for which he is to hold office; but if no such Chairman is elected, or if at any
meeting the Chairman is not present within five minutes after the time appointed
for holding the same, the Directors present may choose one of their number to be
Chairman of the meeting.

89. The Directors may delegate any of their powers to committees consisting of
such member or members of the Board of Directors (including Alternate Directors
in the absence of their appointors) as they think fit; any committee so formed
shall in the exercise of the powers so delegated conform to any regulations that
may be imposed on it by the Directors.

90. A committee may meet and adjourn as it thinks proper. Questions arising at
any meeting shall be determined by a majority of votes of the members present,
and in the case of an equality of votes the Chairman shall have a second or
casting vote.

91. All acts done by any meeting of the Directors or of a committee of Directors
(including any person acting as an alternate Director) shall, notwithstanding
that it be afterwards discovered that there was some defect in the appointment
of any Director or alternate Director, or that they or any of them were
disqualified, be as valid as if every such person had been duly appointed and
qualified to be a Director or alternate Director as the case may be.

92. Members of the Board of Directors or of any committee thereof may
participate in a meeting of the Board or of such committee by means of
conference telephone or similar communications equipment by means of which all
persons participating in the meeting can hear each other and participation in a
meeting pursuant to this provision shall constitute presence in person at such
meeting. A resolution in writing (in one or more counterparts), signed by all
the Directors for the time being or all the members of a committee of Directors
(an alternate Director being entitled to sign such resolution on behalf of his
appointor) shall be as valid and effectual as if it had been passed at a meeting
of the Directors or committee as the case may be duly convened and held.

93. (a) A Director may be represented at any meetings of the Board of Directors
by a proxy appointed by him in which event the presence or vote of the proxy
shall for all purposes be deemed to be that of the Director.
<PAGE>
 
                                       18

     (b) The provisions of Articles 59-62 shall mutatis mutandis apply to the
appointment of proxies by Directors.

                         VACATION OF OFFICE OF DIRECTOR

94. The office of a Director shall be vacated:

     (a)  if he gives notice in writing to the Company that he resigns the
          office of Director;

     (b)  if he absents himself (without being represented by proxy or an
          alternate Director appointed by him) from three consecutive meetings
          of the Board of Directors without special leave of absence from the
          Directors, and they pass a resolution that he has by reason of such
          absence vacated office;

     (c)  if he dies, becomes bankrupt or makes any arrangement or composition
          with his creditors generally;

     (d)  if he is found a lunatic or becomes of unsound mind.

                      APPOINTMENT AND REMOVAL OF DIRECTORS

95. The Company may by ordinary resolution appoint any person to be a Director
and may in like manner remove any Director and may in like manner appoint
another person in his stead.

96. The Directors shall have power at any time and from time to time to appoint
any person to be a Director, either to fill a casual vacancy or as an addition
to the existing Directors but so that the total amount of Directors (exclusive
of alternate Directors) shall not at any time exceed the number fixed in
accordance with these Articles.

                              PRESUMPTION OF ASSENT

97. A Director of the Company who is present at a meeting of the Board of
Directors at which action on any Company matter is taken shall be presumed to
have assented to the action taken unless his dissent shall be entered in the
Minutes of the meeting or unless he shall file his written dissent from such
action with the person acting as the Secretary of the meeting before the
adjournment thereof or shall forward such dissent by registered mail to such
person immediately after the adjournment of the meeting. Such right to dissent
shall not apply to a Director who voted in favour of such action.

                                      SEAL

98. (a) The Company may, if the Directors so determine, have a Seal which shall,
subject to paragraph (c) hereof, only be used by the authority of the Directors
or of a committee of the Directors authorised by the Directors in that behalf
and every instrument to which the Seal has been affixed shall be signed by one
person who shall be either a Director or the Secretary or Secretary-Treasurer or
some person appointed by the Directors for the purpose.
<PAGE>
 
                                       19

     (b) The Company may have a duplicate Seal or Seals each of which shall be a
facsimile of the Common Seal of the Company and, if the Directors so determine,
with the addition on its face of the name of every place where it is to be used.

     (c) A Director, Secretary or other officer or representative or attorney
may without further authority of the Directors affix the Seal of the Company
over his signature alone to any document of the Company required to be
authenticated by him under Seal or to be filed with the Registrar of Companies
in the Cayman Islands or elsewhere wheresoever.

                                    OFFICERS

99. The Company may have a President, a Secretary or Secretary-Treasurer
appointed by the Directors who may also from time to time appoint such other
officers as they consider necessary, all for such terms, at such remuneration
and to perform such duties, and subject to such provisions as to
disqualification and removal as the Directors from time to time prescribe.

                      DIVIDENDS, DISTRIBUTIONS AND RESERVE

100. Subject to the Statute, the Directors may from time to time declare
dividends (including interim dividends) and distributions on shares of the
Company outstanding and authorise payment of the same out of the funds of the
Company lawfully available therefor.

101. The Directors may, before declaring any dividends or distributions, set
aside such sums as they think proper as a reserve or reserves which shall at the
discretion of the Directors, be applicable for any purpose of the Company and
pending such application may, at the like discretion, be employed in the
business of the Company.

102. No dividend or distribution shall be payable except out of the profits of
the Company, realised or unrealised, or out of the share premium account or as
otherwise permitted by the Statute.

103. Subject to the rights of persons, if any, entitled to shares with special
rights as to dividends or distributions, if dividends or distributions are to be
declared on a class of shares they shall be declared and paid according to the
amounts paid or credited as paid on the shares of such class outstanding on the
record date for such dividend or distribution as determined in accordance with
these Articles but no amount paid or credited as paid on a share in advance of
calls shall be treated for the purpose of this Article as paid on the share.

104. The Directors may deduct from any dividend or distribution payable to any
Member all sums of money (if any) presently payable by him to the Company on
account of calls or otherwise.

105. The Directors may declare that any dividend or distribution be paid wholly
or partly by the distribution of specific assets and in particular of paid up
shares, debentures, or debenture stock of any other company or in any one or
more of such ways and where any difficulty arises in regard to such
distribution, the Directors may settle the same as they think expedient and in
particular may issue fractional certificates and fix the value for distribution
of such specific assets or any part thereof and may determine that cash payments
shall be made to any Members upon the footing of the value so
<PAGE>
 
                                       20

fixed in order to adjust the rights of all Members and may vest any such
specific assets in trustees as may seem expedient to the Directors.

106. Any dividend, distribution, interest or other monies payable in cash in
respect of shares may be paid by cheque or warrant sent through the post
directed to the registered address of the holder or, in the case of joint
holders, to the holder who is first named on the register of Members or to such
person and to such address as such holder or joint holders may in writing
direct. Every such cheque or warrant shall be made payable to the order of the
person to whom it is sent. Any one of two or more joint holders may give
effectual receipts for any dividends, bonuses, or other monies payable in
respect of the share held by them as joint holders.

107. No dividend or distribution shall bear interest against the Company.

                                 CAPITALISATION

108. The Company may upon the recommendation of the Directors by ordinary
resolution authorise the Directors to capitalise any sum standing to the credit
of any of the Company's reserve accounts (including share premium account and
capital redemption reserve fund) or any sum standing to the credit of profit and
loss account or otherwise available for distribution and to appropriate such sum
to Members in the proportions in which such sum would have been divisible
amongst them had the same been a distribution of profits by way of dividend and
to apply such sum on their behalf in paying up in full unissued shares for
allotment and distribution credited as fully paid up to and amongst them in the
proportion aforesaid. In such event the Directors shall do all acts and things
required to give effect to such capitalisation, with full power to the Directors
to make such provisions as they think fit for the case of shares becoming
distributable in fractions (including provisions whereby the benefit of
fractional entitlements accrue to the Company rather than to the Members
concerned). The Directors may authorise any person to enter on behalf of all of
the Members interested into an agreement with the Company providing for such
capitalisation and matters incidental thereto and any agreement made under such
authority shall be effective and binding on all concerned.

                                BOOKS OF ACCOUNT

109. The Directors shall cause proper books of account to be kept with respect
to:

     (a)  all sums of money received and expended by the Company and the matters
          in respect of which the receipt or expenditure takes place;

     (b)  all sales and purchases of goods by the Company;

     (c)  the assets and liabilities of the Company.

Proper books shall not be deemed to be kept if there are not kept such books of
account as are necessary to give a true and fair view of the state of the
Company's affairs and to explain its transactions.

110. The Directors shall from time to time determine whether and to what extent
and at what
<PAGE>
 
                                       21

times and places and under what conditions or regulations the accounts and books
of the Company or any of them shall be open to the inspection of Members not
being Directors and no Member (not being a Director) shall have any right of
inspecting any account or book or document of the Company except as conferred by
Statute or authorised by the Directors or by the Company in general meeting.

111. The Directors may from time to time cause to be prepared and to be laid
before the Company in general meeting profit and loss accounts, balance sheets,
group accounts (if any) and such other reports and accounts as may be required
by law.

                                      AUDIT

112. The Company may at any annual general meeting appoint an Auditor or
Auditors of the Company who shall hold office until the next annual general
meeting and may fix his or their remuneration.

113. The Directors may before the first annual general meeting appoint an
Auditor or Auditors of the Company who shall hold office until the first annual
general meeting unless previously removed by an ordinary resolution of the
Members in general meeting in which case the Members at that meeting may appoint
Auditors. The Directors may fill any casual vacancy in the office of Auditor but
while any such vacancy continues the surviving or continuing Auditor or

Special Resolution of the Company and any other sanction required by the
Statute, divide amongst the Members in specie or kind the whole or any part of
the assets of the Company (whether they shall consist of property of the same
kind or not) and may for such purpose set such value as he deems fair upon any
property to be divided as aforesaid and may determine how such division shall be
carried out as between the Members or different classes of Members. The
liquidator may with the like sanction, vest the whole or any part of such assets
in trustees upon such trusts for the benefit of the contributories as the
liquidator, with the like sanction, shall think fit, but so that no Member shall
be compelled to accept any shares or other securities whereon there is any
liability.

122. If the Company shall be wound up, and the assets available for distribution
amongst the Members as such shall be insufficient to repay the whole of the
paid-up capital, such assets shall be distributed so that, as nearly as may be,
the losses shall be borne by the Members in proportion to the capital paid up,
or which ought to have been paid up, at the commencement of the winding up on
the shares held by them respectively. And if in a winding up the assets
available for distribution amongst the Members shall be more than sufficient to
repay the whole of the capital paid up at the commencement of the winding up,
the excess shall be distributed amongst the Members in proportion to the capital
paid up at the commencement of the winding up on the shares held by them
respectively.

     SECTION 1.02. Compliance Certificates and Opinions.

     Except as otherwise expressly provided by this Indenture, upon any
application or request by the Company to the Trustee to take any action under
any provision of this Indenture, the Company shall furnish to the Trustee an
Officers' Certificate stating that all conditions precedent, if any, provided
for in this Indenture relating to the proposed action have been complied with
and an Opinion of Counsel stating that in the opinion of such counsel all such
conditions precedent, if any, have been complied with, except that in the case
of any such application or request as to which the furnishing of such documents
is specifically required by any provision of this Indenture 


                                       10
<PAGE>
 
relating to such particular application or request, no additional certificate or
opinion need be furnished.

     Every certificate or opinion with respect to compliance with a condition or
covenant provided for in this Indenture shall include:

          (1) a statement that each individual signing such certificate or
     opinion has read such covenant or condition and the definitions herein
     relating thereto;

          (2) a brief statement as to the nature and scope of the examination or
     investigation upon which the statements or opinions contained in such
     certificate or opinion are based;

          (4) a statement as to whether, in the opinion of each such individual,

such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

     Any certificate or opinion of an officer or Director may be based, insofar

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

applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.




                                       11

     SECTION 1.04. Acts of Holders.

     (a) Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Indenture to be given or taken by Holders may
be embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Holders in Person or by agent duly appointed in writing,
and, except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments are delivered to the Trustee and,
where it is hereby expressly required, to the Company. Such instrument or
instruments (and the action embodied therein and evidenced thereby) are herein
sometimes referred to as the "Act" of the Holders signing such instrument or
instruments. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture
and (subject to Section 6.01) conclusive in favor of the Trustee and the
Company, if made in the manner provided in this Section 1.04.

     Without limiting the generality of the foregoing, unless otherwise
established in or pursuant to a Board Resolution or set forth or determined in
an Officers' Certificate, or established in one or more indentures supplemental
hereto, pursuant to Section 2.05, a Holder, including a Book-Entry Depositary
that is a Holder of a Global Security, may make, give or take, by a proxy, or
proxies, duly appointed in writing, any request, demand, authorization,
direction, notice, consent, waiver or other action provided in this Indenture to
be made, given or taken by Holders, and a Book-Entry Depositary that is a Holder
of a Global Security may provide its proxy or proxies to the beneficial owners
of interests in any such Global Security through such Book-Entry Depositary's
standing instructions and customary practices.

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

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

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

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




                                       12
<PAGE>
 
     (e) The principal or face amount and serial numbers of Bearer Securities of
any series held by any Person, and the date of holding the same, may be proved
by the production of such Bearer Securities or by a certificate executed by the
Book-Entry Depositary for such Bearer Securities.

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

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

     On or prior to any expiration date set pursuant to this subsection, the
Company may, on one or more occasions at its option, extend such expiration date
to any later date. Nothing in this subsection shall prevent any Holder (or any
duly appointed agent thereof) from taking, at any time, any action contrary to
or different from, any action previously taken, or purported to have been taken,
hereunder by such Holder, in which event the Company may set a record date in
respect thereof pursuant to this subsection. Notwithstanding the foregoing or
the Trust Indenture Act, the Company shall not set a record date for, and the
provisions of this paragraph shall not apply with respect to, any action to be
taken by Holders pursuant to Section 5.01 or 5.06.

     Upon receipt by the Trustee of written notice of any default described in
Section 5.01, any declaration of acceleration, or any rescission and annulment
of any such declaration, pursuant to Section 5.01 or of any direction in
accordance with Section 5.06, a record date shall automatically and without any
other action by any Person be set for the purpose of determining the Holders of
Outstanding Securities of the series entitled


                                       13
<PAGE>
 
to join in such notice, declaration, or rescission and annulment, or direction,
as the case may be, which record date shall be the close of business on the day
the Trustee receives such notice, declaration, rescission and annulment or
direction, as the case may be. The Holders of Outstanding Securities of such
series on such record date (or their duly appointed agent), and only such
Persons, shall be entitled to join in such notice, declaration, rescission and
annulment, or direction, as the case may be, whether or not such Holders remain
Holders after such record date; provided that, unless such notice, declaration,
rescission and annulment, or direction, as the case may be, shall have become
effective by virtue of Holders of the requisite principal amount of Outstanding
Securities of such series on such record date (or their duly appointed agents)
having joined therein on or prior to the 90th day after such record date, such
notice of default, declaration, rescission and annulment, or direction, as the
case may be, given or made by the Holders, as the case may be, shall
automatically and without any action by any Person be canceled and of no further
effect. Nothing in this paragraph shall prevent a Holder (or a duly appointed
agent thereof) from giving, before or after the expiration of such 90-day
period, a notice of default, a declaration of acceleration, a rescission and
annulment of a declaration of acceleration or a direction in accordance with
Section 5.06, contrary to or different from, or, after the expiration of such
period, identical to, a previously given notice, declaration, rescission and
annulment, or direction, as the case may be, that has been canceled pursuant to
the proviso to the preceding sentence, in which event a new record date in
respect thereof shall be set pursuant to this paragraph.

     SECTION 1.05. Notices, Etc., to Trustee and Company.

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

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

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

     SECTION 1.06. Notice to Holders; Waiver.

     Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, (i) in the case of a Holder of Registered Securities, at his
address as it appears in the Security Register, and (ii) in the case of a Holder
of Global Bearer Securities, at the address


                                       14
<PAGE>
 
provided in or pursuant to the relevant Deposit Agreement of the relevant
Book-Entry Depositary, not later than the latest date, and not earlier than the
earliest date, prescribed for the giving of such notice. In any case where
notice to Holders is given by mail, neither the failure to mail such notice, nor
any defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders.

     If Securities of any series are listed on the Luxembourg Stock Exchange and
the rules of such Stock Exchange so require, notice to Holders of such
Securities shall be published in a leading newspaper having general circulation
in Luxembourg.

     If, by reason of the suspension of regular mail service or by reason of any
other cause, it shall be impracticable to give such notice by mail, then such
notification as shall be made at the direction of the Company in a manner
reasonably calculated, to the extent practicable under the circumstances, to
provide prompt notice shall constitute a sufficient notification for every
purpose hereunder.

     Except as otherwise expressly provided herein or otherwise specified with
respect to any Securities pursuant to Section 2.05, where this Indenture
provides for notice to Holders of Bearer Securities of any event and the rules
of any securities exchange on which such Bearer Securities are listed so
require, such notice shall be sufficiently given to Holders of such Bearer
Securities if published in such newspaper or newspapers as may be specified in
such Securities on a Business Day at least twice, the first such publication to
be not earlier than the earliest date, and not later than the latest date,
prescribed for the giving of such notice. Any such notice by publication shall
be deemed to have been given on the date of the first such publication. In
addition, notice to the Holder of any Global Bearer Security shall be given by
mail in the manner provided above.

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

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

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

     SECTION 1.07. Conflict with Trust Indenture Act.

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

     SECTION 1.08. Effect of Headings and Table of Contents.

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

     SECTION 1.09. Successors and Assigns.

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

     SECTION 1.10. Separability Clause.

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

     SECTION 1.11. Benefits of Indenture.

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

     SECTION 1.12. Governing Law.

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

     SECTION 1.13. Legal Holidays.

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


                                       16
<PAGE>
 
from and after such Interest Payment Date, Redemption Date or Stated Maturity,
as the case may be.

                                   ARTICLE II

                                   SECURITIES

Certificate delivered pursuant thereto) or in each case with such appropriate
insertions, omissions, substitutions and other variations as are required or

identification and such legends or endorsements placed thereon as may be
required to comply with the rules of any securities exchange or as may,
consistently herewith, be determined by the Director or Directors executing such
Securities, as evidenced by the Director's or Directors' execution of the
Securities. If the form of Securities of any series is established by action
taken pursuant to a Board Resolution, a copy of an appropriate record of such
action shall be certified by an authorized Director or officer of the Company
and delivered to the Trustee at or prior to the delivery of the Company Order
contemplated by Section 2.07 for the authentication and delivery of such
Securities.

     The Trustee's certificates of authentication shall be in substantially the
form set forth in this Article or in a Board Resolution (or Officers'
Certificate delivered pursuant thereto) or an indenture supplemental hereto.

     The definitive Securities shall be printed, lithographed or engraved on
steel engraved borders or may be produced in any other manner, all as determined
by the Director or Directors executing such Securities, as evidenced by the
Director's or Directors' execution of such Securities.

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

     series pursuant to Section 2.09, 2.10 or 2.11 and except for any Securities
     which, pursuant to Section 2.07, are deemed never to have been
     authenticated and delivered hereunder);

          (c) the Person or Persons (without specific identification) to whom
     interest on Securities of such series shall be payable on any Interest
     Payment Date, if other than the bearer (in the case of a Bearer Security)
     or the Persons in whose names such Securities (or one or more Predecessor
     Securities) are registered at the close of business on the Regular Record
     Date for such interest;

          (d) the date or dates, if any, on which the principal of the
     Securities of such series is payable or any formulary or other method or
     other means by which such date or dates shall be determined, by reference
     to an index or other fact or event ascertainable outside this Indenture or
     otherwise (without regard to any 


                                       19
<PAGE>
 
     provisions for redemption, prepayment, declaration of acceleration,
     purchase or extension);

          (e) the rate or rates at which the Securities of such series shall
     bear interest, if any (including the rate or rates at which overdue
     principal shall bear interest, if different from the rate or rates at which
     such Securities shall bear interest prior to the Stated Maturity, if any,
     and, if applicable, the rate or rates at which overdue premium or interest
     shall bear interest, if any), or any formulary or other method or other
     means by which such rate or rates shall be determined, by reference to an
     index or other fact or event ascertainable outside this Indenture or
     otherwise; the date or dates from which such interest shall accrue; the
     Interest Payment Dates on which such interest shall be payable and the
     Regular Record Date, if any, for the interest payable on such Securities on
     any Interest Payment Date; the right of the Company, if any, to extend the
     interest payment periods and the duration of any such extension or to defer
     the payment of interest; the obligation of the Company to pay Additional

<PAGE>
 
          (s) if the Securities of such series are to be issued in whole or in

     owners of interests in any such Global Security or Securities may exchange

     which any such changes may occur, if other than in the manner provided in
     Section 2.10 and (ii) to Book-Entry Depositary for such Global Security or
     Securities;

          (t) if the Securities of such series are to be issuable as definitive
     Bearer Securities, any and all matters incidental thereto which are not
     specifically addressed in a supplemental indenture as contemplated by
     clause (g) of Section 9.01;

          (u) to the extent not established pursuant to clause (s) of this
     paragraph, any limitations on the rights of the Holders of the Securities
     of such Series to transfer or exchange such Securities or to obtain the
     registration of transfer thereof; and if a service charge will be made for
     the registration of transfer or exchange of Securities of such series the
     amount or terms thereof;

          (v) any exceptions to Section 1.01, or variation in the definition of

          (x) if Article XV and the other provisions of this Indenture relating
     to the Guarantee of the Securities are applicable to such series; and

          (y) any other terms of the Securities of such series not inconsistent
     with the provisions of this Indenture.


     The Securities of each series shall be subordinated in right of payment to
Senior Debt as provided in Article XIV.

     SECTION 2.06. Denominations.

     The Securities of each series shall be issuable in bearer form or in
registered form without coupons, except as otherwise expressly provided in a
supplemental indenture hereto, in such denominations as shall be specified as
contemplated by Section 2.05. In the absence of any such provisions with respect
to the Securities of any series, the Securities of such series shall be issuable
in denominations of $25 and any integral multiple thereof.

     SECTION 2.07. Execution, Authentication, Delivery and Dating.

     The Securities shall be executed on behalf of the Company by any Director,
the Secretary or any other signatory of the Company so authorized and need not
be attested. Definitive Registered Securities of any series may have the
Company's seal 


                                       22
<PAGE>
 
reproduced thereon which need not be attested. The Securities of any series
shall be executed by such additional Director or authorized signatory, if any,
as shall be specified pursuant to Section 2.05. The signature of any of these
authorized signatories on the Securities may be manual or facsimile.

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

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities. If the
form or terms of the Securities of the series have been established in or
pursuant to one or more Board Resolutions as permitted by Sections 2.01 and
2.05, in authenticating such Securities, and accepting the additional
responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, and (subject to Section 6.01) shall be
fully protected in relying upon, an Opinion of Counsel stating,

          (a) if the form of such Securities has been established by or pursuant
     to Board Resolution as permitted by Section 2.01, that such form has been
     established in conformity with the provisions of this Indenture;

          (b) if the terms of such Securities have been established by or
     pursuant to Board Resolution as permitted by Section 2.05, that such terms
     have been established in conformity with the provisions of this Indenture;
     and

          (c) that such Securities, when authenticated and delivered by the
     Trustee and issued by the Company in the manner and subject to any
     conditions specified in such Opinion of Counsel, will constitute valid and
     legally binding obligations of the Company, enforceable in accordance with
     their terms, subject to bankruptcy, insolvency, reorganization and other
     laws of general applicability relating to or affecting the enforcement of
     creditors' rights and to general principles of equity.

     Notwithstanding the provisions of Section 2.05 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 2.05 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the time
of authentication of each Security of such series if such documents are
delivered at or prior to the time of authentication upon original issuance of
the first Security of such series to be issued.

     Each Security shall be dated the date of its authentication.




                                       23
<PAGE>
 
     No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee or an Authenticating Agent by manual signature, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered hereunder
and is entitled to the benefits of this Indenture. Notwithstanding the
foregoing, if any Security shall have been authenticated and delivered hereunder
but never issued and sold by the Company, and the Company shall deliver such
Security to the Trustee for cancellation as provided in Section 2.14 together
with a written statement (which need not be accompanied by an Opinion of
Counsel) stating that such Security has never been issued and sold by the
Company, for all purposes of this Indenture such Security shall be deemed never
to have been authenticated and delivered hereunder and shall never be entitled
to the benefits of this Indenture.

     SECTION 2.08. Transfer Agent and Paying Agent.

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

     The Company shall enter into an appropriate agency agreement with any
Registrar, Transfer Agent or Paying Agent not a party to this Indenture, which
shall implement the provisions of this Indenture that relate to such Person. The
Company shall notify the Trustee of the name and address of any such Person. If
the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act
as such and shall be entitled to appropriate compensation therefor pursuant to
Section 6.06. The Company initially appoints the Trustee as Registrar, Transfer
Agent and Principal Paying Agent in The City of New York and Banque Generale du
Luxembourg S.A. as Paying Agent and Transfer Agent in Luxembourg in connection
with the Securities.

     Banque Generale du Luxembourg S.A. shall be responsible for only those
duties that are described in the provisions of this Indenture that relate to the
Paying Agent and Transfer Agent. No implied duties or obligations shall be read
into this Indenture against Banque Generale du Luxembourg S.A. It is understood
and agreed that the actions taken by Banque Generale du Luxembourg S.A. as
Paying Agent and Transfer Agent shall be limited to actions including definitive
Registered Securities.

     SECTION 2.09. Temporary Securities.

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


                                       24
<PAGE>
 
officers executing such Securities may determine, as evidenced by their
execution of such Securities.

     If temporary Securities of any series are issued, the Company will cause
definitive Securities of that series to be prepared without unreasonable delay.
After the preparation of definitive Securities of such series, the temporary
Securities of such series shall be exchangeable for definitive Securities of
such series upon surrender of the temporary Securities of such series at the
office or agency of the Company in a Place of Payment for that series, without
charge to the Holder except as provided in Section 2.10 in connection with a
transfer and except that a Person receiving definitive Bearer Securities shall
bear the cost of insurance, postage, transportation and the like. Upon surrender
for cancellation of any one or more temporary Securities of any series the
Company shall execute and the Trustee or the Authenticating Agent shall
authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of the same series and of like tenor of authorized
denominations.

     Upon any exchange of a portion of a temporary Global Security for a
definitive Global Security for the individual Securities represented thereby
pursuant to this Section 2.09 or Section 2.10, the temporary Global Security
shall be endorsed by the Trustee to reflect the reduction of the principal
amount of such temporary Global Security, and such principal amount shall be
reduced for all purposes by the amount so exchanged and endorsed.

     SECTION 2.10. Registration, Registration of Transfer and Exchange.

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

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

     At the option of the Holder, any Registered Security or Registered
Securities of any series, other than a Global Security, may be exchanged for
other Registered Securities of the same series, of any authorized denominations
and of a like aggregate principal amount and tenor, upon surrender of the
Registered Securities to be


                                       25
<PAGE>
 
exchanged at such office or agency. Whenever any Securities are so surrendered
for exchange, the Company shall execute, and upon receipt of a Company Order the
Trustee or the Authenticating Agent shall authenticate and deliver, the
Registered Securities which the Holder making the exchange is entitled to
receive. Bearer Securities may not be delivered by the Trustee, the
Authenticating Agent or the Security Registrar in exchange for Registered
Securities.

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

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

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

     No service charge shall be made to the Holder for any registration of
transfer or exchange of Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Sections 2.09 or 13.05 not involving any transfer.




                                       26
<PAGE>
 
     The Company shall not be required (i) to issue, register the transfer of or
exchange Securities of any series during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption under
Section 13.03 and ending at the close of business on the day of such mailing,
(ii) to register the transfer of or exchange any Security so selected for
redemption in whole or in part, except the unredeemed portion of any Security
being redeemed in part or (iii) to exchange any Bearer Security so selected for
redemption except that such a Bearer Security may be exchanged for a Registered
Security of the series (but only if and under the circumstances for which the
Securities of such series are issuable as Registered Securities), provided that
such Registered Security shall be immediately surrendered for redemption with
written instructions for payment consistent with the provisions of this
Indenture.

     The provisions of this Section 2.10 are, with respect to any Global
Security, subject to Section 2.16 hereof.

     SECTION 2.11. Mutilated, Destroyed, Lost and Stolen Securities.

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

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

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

     Upon the issuance of any new Security under this Section 2.11, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

     Every new Security of any series issued pursuant to this Section 2.11 in
lieu of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities of that series duly issued hereunder.



                                       27
<PAGE>
 
     The provisions of this Section 2.11 are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities.

     SECTION 2.12. Payment of Interest; Interest Rights Reserved.


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

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

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

          (1) The Company may elect to make payment of any Defaulted Interest to
     the Persons in whose names the Registered Securities of such series (or
     their respective Predecessor Securities) are registered at the close of
     business on a Special Record Date for the payment of such Defaulted
     Interest, which shall be fixed in the following manner. The Company shall
     notify the Trustee in writing of the amount of Defaulted Interest proposed
     to be paid on each Registered Security of such series and the date of the
     proposed payment, and at the same time the Company shall deposit with the
     Trustee an amount of money equal to the aggregate amount proposed to be
     paid in respect of such Defaulted Interest or shall make arrangements
     satisfactory to the Trustee for such deposit prior to the date of the
     proposed payment, such money when deposited to be held in trust for the
     benefit of the Persons entitled to such Defaulted Interest as in this
     clause provided. Thereupon the Trustee shall fix a Special Record Date for
     the payment of such Defaulted Interest which shall be not more than 15 days
     and not less than 10 days prior to the date of the proposed payment and not
     less than 10 days after the receipt by the Trustee of the notice of the
     proposed payment. Unless the 


                                       28
<PAGE>
 
     Trustee is acting as the Security Registrar, promptly after such Special
     Record Date, the Company shall furnish the Trustee with a list, or shall
     make arrangements satisfactory to the Trustee with respect thereto, of the
     names and addresses of, and respective principal amounts of such Registered
     Securities held by, the Holders appearing on the Security Register at the
     close of business on such Special Record Date. The Trustee shall promptly
     notify the Company of such Special Record Date and, in the name and at the
     expense of the Company, shall cause notice of the proposed payment of such
     Defaulted Interest and the Special Record Date therefor to be mailed,
     first-class postage prepaid, to each Holder of Securities of such series at
     his address as it appears in the Security Register, not less than 10 days
     prior to such Special Record Date. Notice of the proposed payment of such
     Defaulted Interest and the Special Record Date therefor having been so
     mailed, such Defaulted Interest shall be paid to the Persons in whose names
     the Securities of such series (or their respective Predecessor Securities)
     are registered at the close of business on such Special Record Date and
     shall no longer be payable pursuant to the following clause (2).

          (2) The Company may make payment of any Defaulted Interest on the
     Registered Securities of any series or any Global Registered Security in
     any other lawful manner not inconsistent with the requirements of any
     securities exchange on which such Registered Securities may be listed, and
     upon such notice as may be required by such exchange.

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

     Subject to the foregoing provisions of this Section 2.12, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security, shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

     SECTION 2.13. Persons Deemed Owners.

     Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Registered Security is registered as the
owner of such Registered Security for the purpose of receiving payment of
principal of, premium, if any, and (subject to Section 2.12) interest, if any,
on such Registered Security and for all other purposes whatsoever, whether or
not such Registered Security be overdue, and neither the Company, the Trustee
nor any agent of the Company or the Trustee shall be affected by notice to the
contrary. All such payments so made to any such person, or upon such person's
order, shall be valid, and, to the extent of the sums so paid, effectual to
satisfy and discharge the liability for monies payable upon any such Security.

     The Company, the Trustee and any agent of the Company or the Trustee may
treat the Book-Entry Depositary for a Global Bearer Security as the absolute
owner of such Global Bearer Security for the purpose of receiving payment
thereof or on 


                                       29
<PAGE>
 
account thereof and for all other purposes whatsoever, whether or not such
Global Bearer Security or coupon be overdue, and neither the Company or the
Trustee nor any agent of the Company or the Trustee shall be affected by notice
to the contrary.

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

     SECTION 2.14. Cancellation.

     All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly canceled by it. The Company may at any time deliver to the
Trustee for cancellation any Securities previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and all
Securities so delivered shall be promptly canceled by the Trustee. No Securities
shall be authenticated in lieu of or in exchange for any Securities canceled as
provided in this Section 2.14, except as expressly permitted by this Indenture.
All canceled Securities held by the Trustee shall be disposed of as directed by
a Company Order.

     SECTION 2.15. Computation of Interest.

     Except as otherwise specified as contemplated by Section 2.05 for
Securities of any series, interest, if any, on the Securities of each series
shall be computed on the basis of a 360-day year of twelve 30-day months. In the
event that any date on which an interest payment is payable on the Securities 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 (an 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.

     SECTION 2.16. Global Securities.

     If the Company shall establish pursuant to Section 2.05 that the Securities
of a particular series are to be issued in the form of a Global Security, then
the Company shall execute and the Trustee shall, in accordance with Section
2.07, authenticate and deliver, a Global Security or Securities which (i) shall
represent, and shall be denominated in an aggregate amount equal to the
aggregate principal amount of, all of the Outstanding Securities of such series,
(ii) shall be in bearer form or, if in registered form, registered in the name
of the Book-Entry Depositary or its nominee, (iii) shall be 


                                       30
<PAGE>
 
delivered by the Trustee to the Book-Entry Depositary or pursuant to the
Book-Entry Depositary's instruction and (iv) shall bear a legend substantially
to the following effect:

     "This Security is a Global Security within the meaning of the Indenture
hereinafter referred to and if this Security is in bearer form, is held by a
Book-Entry Depositary or, if this Security is in registered form, is registered
in the name of a Book-Entry Depositary or a nominee of a Book-Entry Depositary.
This Security is exchangeable for Securities, if this Security is in bearer
form, held by, or if this Security is in registered form, registered in the name
of, a person other than the Book-Entry Depositary or its nominee only in the
limited circumstances described in the Indenture.

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

     Unless and until definitive Registered Securities of a series are issued in
exchange for the Global Security of a series as permitted by this Indenture, the
Global Security of a series may be transferred, in whole but not in part and in
the manner provided in Section 2.10, only to another nominee of the Book-Entry
Depositary for such series, or to a successor Book-Entry Depositary for such
series selected or approved by the Company or to a nominee of such successor
Book-Entry Depositary.

     No Security that is not a Global Bearer Security may be payable to bearer
(except as otherwise provided in an indenture supplemental hereto or in an
Officers' Certificate (pursuant to a Board Resolution) pursuant to Section
2.05(s)).

     SECTION 2.17. Extension of Interest Payment Period; Deferral of Interest
Payment.

     The Company shall have the right at any time, so long as no Event of
Default shall have occurred and be continuing with respect to the Securities of
any series hereunder, to extend interest payment periods, or to defer the
payment of interest, on all Securities of one or more series, if so specified as
contemplated by Section 2.05 with respect to such Securities and upon such terms
as may be specified as contemplated by Section 2.05 with respect to such
Securities.

     SECTION 2.18. CUSIP Numbers.

     The Company in issuing the Securities of any series may use "CUSIP" numbers
(if then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in
notices of redemption as a convenience to Holders; provided that any such notice
may state that no representation is made as to the correctness of such numbers
either as printed on the Securities of such series or as contained in any notice
of a redemption and that


                                       31
<PAGE>
 
reliance may be placed only on the other identification numbers printed on the
Securities of such series, and any such prepayment shall not be affected by any
defect in or omission of such numbers. The Company will promptly notify the
Trustee of any change in the CUSIP numbers.


                                   ARTICLE III

                                    COVENANTS

     SECTION 3.01. Payment of Principal, Premium and Interest.

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

     When Securities of a series or Book-Entry Interests are held by a Business
Trust, neither the Company, the Guarantor, nor any agent of the Company or the
Guarantor will have any responsibility or liability for any aspect relating to
payments made or to be made by the Book-Entry Depositary to the Business Trust
in respect of the Securities of a series or the Book-Entry Interests. When
Securities of a series or Book-Entry Interest are held by DTC, neither the
Company, the Guarantor, nor any agent of the Company or the Guarantor will have
any responsibility or liability for any aspect relating to payments made or to
be made by the Book-Entry Depositary to DTC in respect of the Securities of a
series or the Book-Entry Interests. None of the Company, the Trustee, the
Book-Entry Depositary or any agent of any of the foregoing will have any
responsibility or liability for any aspect relating to payments made or to be
made by DTC on account of a participant's or indirect participant's ownership of
an interest in the Book-Entry Interests or for maintaining, supervising or
reviewing any records relating to a participant's interests in the Book-Entry
Interests.

     SECTION 3.02. Maintenance of Office or Agency.

     The Company will maintain (i) in the Borough of Manhattan, The City of New
York, an office or agency where Securities of any series may be presented or
surrendered for payment, and where notices and demands to or upon the Company in
respect of the Securities of such series and this Indenture may be served and if
definitive Registered Securities have been issued, an office or agency of a
Transfer Agent where Securities may be surrendered for registration of transfer
or exchange, and (ii) an office or agency of a Paying Agent where the Securities
may be paid in Luxembourg so long as the Securities are listed on the Luxembourg
Stock Exchange and the rules of such exchange so require. The Company will give
prompt written notice to the Trustee of the location, and any change in the
location, of any such office or agency. If at any time the 


                                       32
<PAGE>
 
Company shall fail to maintain any such required office or agency or shall fail
to furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the corporate trust office of the
Trustee, except that Bearer Securities of that series pursuant to Section 13.01
may be presented at the place specified for the purpose pursuant to Section
2.05, and the Company hereby appoints the Paying Agent as its agent to receive
all such presentations, surrenders, notices and demands.

     The Company may also from time to time designate one or more other offices
or agencies (in or outside of such Place of Payment) where the Securities of one
or more series and any appurtenant coupons (subject to Section 13.01) may be
presented or surrendered for any or all of such purposes, and may from time to
time rescind such designations; provided, however, that no such designation or
rescission shall in any manner relieve the Company of its obligation to maintain
an office or agency in each Place of Payment for any series of Securities for
such purposes. The Company will give prompt written notice to the Trustee of any
such designation and any change in the location of any such other office or
agency. The Company will at all times maintain at least one Paying Agent which
is located outside the United Kingdom for each series of Securities.

     SECTION 3.03. Money for Securities Payments to Be Held in Trust.

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

     Whenever the Company shall have one or more Paying Agents for any series of
Securities, it will, no later than 11:00 a.m., New York City time, on or prior
to each due date of the principal of, premium, if any, or interest, if any, on
any Securities of that series, deposit with a Paying Agent a sum in immediately
available funds sufficient to pay the principal, premium, if any, or interest so
becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium or interest.

     The Company will cause each Paying Agent for any series of Securities other
than the Trustee to execute and deliver to the Trustee an instrument in which
such Paying Agent shall agree with the Trustee, subject to the provisions of
this Section 3.03, that such Paying Agent will:

          (1) hold all sums held by it for the payment of the principal of,
     premium, if any, or interest, if any, on Securities of that series in trust
     for the benefit of the Persons entitled thereto until such sums shall be
     paid to such Persons or otherwise disposed of as herein provided;


                                       33
<PAGE>
 
          (2) give the Trustee notice of any default by the Company (or any
     other obligor upon the Securities of that series) in the making of any
     payment of principal of, premium, if any, or interest, if any, on the
     Securities of that series; and

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

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


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

     SECTION 3.04. Appointments to Fill Vacancies in Trustee's Office.

     The Company, whenever necessary to avoid or fill a vacancy in the office of
Trustee, will appoint, in the manner provided in Section 6.10, a Trustee, so
that there shall at all times be a Trustee hereunder.

     SECTION 3.05. Certificate to Trustee.

     The Guarantor will deliver to the Trustee on or before 120 days after the
end of each fiscal year in each year, commencing with the first fiscal year
ending after the date hereof, so long as Securities of any series are
outstanding hereunder, an Officers' Certificate, stating that in the course of
the performance by the signers of their duties as officers of the Guarantor they
would normally have knowledge of any default by the Guarantor in the performance
of any covenants contained herein, stating whether or not they have knowledge of
any such default and, if so, specifying each such default of which the signers
have knowledge and the nature thereof.

     SECTION 3.06. Compliance with Consolidation Provisions.

     Neither the Company nor the Guarantor will, while any of the Securities of
any series remain outstanding, consolidate with, or merge or convert into, or
merge or convert into itself, or sell or convey all or substantially all of its
property to, any other Person unless the provisions of Article X hereof are
complied with.

     SECTION 3.07. Limitation on Dividends.

Guarantee (or any other guarantee by the Guarantor 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
Securities); (c) payments by the Guarantor under the Guarantee; (d) any dividend
or payment by the Guarantor which is applied, directly or indirectly, to any Tax
Payments (e) payments by the Guarantor, directly or indirectly, on the
Intercompany Notes or any other promissory notes held by the Company (or any
other direct or indirect wholly-owned subsidiary of the Guarantor) evidencing
loans made with the proceeds from the issuance by the Company (or any other
direct or indirect wholly-owned subsidiary of the Guarantor) of securities
guaranteed by the Guarantor or (f) the reinvestment of any proceeds received
under clause (e) above by the Company (or any other direct or indirect
wholly-owned subsidiary of the Guarantor) in additional debt securities of the
Guarantor 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
pursuant to Section 5.01(a) or 5.01(b) (whether before or after any period of
grace) or an Event of Default hereunder with respect to any series of
Securities, (ii) the Guarantor shall be in default with respect to its payment

     SECTION 3.08. Covenants as to the Related Business Trust.

     (a) In the event Securities of any series are issued to a Business Trust or
a trustee of such trust in connection with the issuance of Trust Securities by
such Business Trust, for so long as such Trust Securities remain outstanding,
Yorkshire Group shall use its reasonable efforts, consistent with the terms and
provisions of the Trust Agreement of such Business Trust, to cause (a) such
Business Trust to not be classified as anything other than a grantor trust for
United States Federal income tax purposes, (b) such Business Trust to remain a
trust falling within the provisions of Section 60 United Kingdom of Chargeable
Gains Act of 1992 ("Section 60") and not to be treated as a company for purposes

Business Trust not to be required to register as an "investment company" under
the Investment Company Act.

     SECTION 3.09. Covenants as to Treatment of Securities.

     The Guarantor and the Company covenant to treat each series of Securities
as indebtedness of the Company for all United States Federal income tax
purposes.

     SECTION 3.10. Additional Interest.

     If the Securities of a series provide for the payment of Additional
Interest to the holders of such Securities, then the Guarantor or the Company,
as the case may be, shall pay to each holder of such Securities the Additional
Interest as provided therein.

     SECTION 3.11. Waiver of Certain Covenants.

     The Company or the Guarantor may omit in any particular instance to comply
with any term, provision or condition set forth in this Indenture with respect
to the Securities of any series if before the time for such compliance the
Holders of at least a majority in aggregate principal amount of the Outstanding
Securities of such series shall, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such term,
provision or condition, provided that no such waiver shall without the consent
of each Holder affected thereby (a) change the Stated Maturity, if any, upon

waiver of compliance with certain provisions of the Indenture or certain
defaults hereunder and their consequences provided for in the Indenture;
provided, however, 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


                                       36
<PAGE>
 
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 series of Securities relating to such Trust Securities and all accrued and
unpaid interest or other amounts thereon have been paid in full.

     SECTION 3.12. Payment of Additional Amounts.

     Unless the Securities of a particular series otherwise provide, all
payments of principal and interest (including payments of discount and premium,
if any) with respect to the Securities of a particular series and all payments
made pursuant to the 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, the Company
or the Guarantor, as the case may be, shall pay to the Holder of such Securities
the amount that would otherwise have been due to such Holder in the absence of
such withholding or deduction ("Additional Amounts"), except that no such
Additional Amounts shall be payable:

     (a) to, or to a Person on behalf of, a Holder who is liable for such
Gross-Up Taxes with respect to the Securities or the 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 Security or the
receipt of principal and interest (including payments of discount and premium,
if any) in respect thereof or in respect of the Guarantee;

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

     (c) to, or to a Person on behalf of, a Holder who presents a Security
(where presentation is required) in the United Kingdom 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 Registered Security that
is not a Global Security issued pursuant to the request of owners of interests
representing a majority in Outstanding principal amount of such Securities
following and 


                                       37
<PAGE>
 
during the continuance of an Event of Default if such Holder (or any predecessor
Holder) was one of such owners requesting that such Registered Securities be so
issued.

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

     At least 30 Business Days prior to the first Interest Payment Date (and at
least 10 Business Days prior to each succeeding Interest Payment Date if there
has been any change with respect to the matters set forth in the below-mentioned
Officers' Certificate) the Company will furnish to the Trustee and any Paying
Agent an Officers' Certificate instructing the Trustee and any Paying Agent
whether payments of principal of or interest on the Securities is due on such
Interest Payment Date shall be without deduction or withholding for or on
account of any Gross-Up Taxes. If any such deduction or withholding shall be
required, prior to such Interest Payment Date the Company will furnish the
Trustee and any Paying Agent with an Officers' Certificate which specifies the
amount, if any, required to be withheld on such payment to Holders and certifies
that the Company shall pay such withholding or deduction. The Company covenants
to indemnify the Trustee for, and to hold the Trustee harmless against, any
loss, liability or expense reasonably incurred without negligence, willful
misconduct or bad faith on their part, arising out or in connection with actions
taken or omitted by the Trustee in reliance on any Officers' Certificate
furnished pursuant to this paragraph. Any Officers' Certificate required by this
Section 3.12 to be provided to the Trustee and any Paying Agent shall be deemed
to be duly provided if telecopied to the Trustee and such Paying Agent.

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

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

     SECTION 3.13. Copies Available to Holders.

     Copies of this Indenture shall be available for inspection by the Holders
on a Business Day during normal business hours at the principal office of the
Company and at the corporate trust office. In addition, if the Securities of any
series are listed on the London Stock Exchange, the Luxembourg Stock Exchange or

exchange shall so require, copies of this Indenture, the Deposit Agreement, the
Letter of Representations, the memorandum and 


                                       38

     SECTION 3.14. Company Covenants.

     The Company covenants (i) to not, at any time, be engaged in a United
States trade or business for United States Federal income tax purposes and (ii)
to remain a partnership and not to be classified as an association or publicly
traded partnership taxable as a corporation for United States Federal income tax
purposes.

     SECTION 4.01. Holders' Lists

     The Company covenants and agrees that it will furnish or cause to be

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

possession thereof by reason of its acting as Security Registrar.

     SECTION 4.02. Preservation and Disclosure of Lists.

     (a) The Trustee shall preserve, in as current a form as is reasonably
practicable, all information as to the names and addresses of the Holders of the
Securities of a series (1) contained in the most recent list furnished to it as
provided in Section 4.01 or (2) received by it in the capacity of Securities
Registrar (if so acting) hereunder. The Trustee may destroy any list furnished
to it as provided in Section 4.01 upon receipt of a new list so furnished.

     (b) In case three or more Holders of Securities of a series (hereinafter
referred to as "applicants") apply in writing to the Trustee and furnish to the
Trustee 


                                       39
<PAGE>
 
reasonable proof that each such applicant has owned a Security for a period of
at least six months preceding the date of such application, and such application
states that the applicants desire to communicate with other Holders of
Securities of such series or with Holders of all Securities with respect to
their rights under this Indenture and is accompanied by a copy of the form of
proxy or other communication which such applicants propose to transmit, then the
Trustee shall within 5 Business Days after the receipt of such application, at
its election, either:

          (1) afford such applicants access to the information preserved at the
     time by the Trustee in accordance with the provisions of subsection (a) of
     this Section 4.02; or

          (2) inform such applicants as to the approximate number of Holders of
     all Securities, whose names and addresses appear in the information
     preserved at the time by the Trustee in accordance with the provisions of
     subsection (a) of this Section 4.02, and as to the approximate cost of
     mailing to such Holders the form of proxy or other communication, if any,
     specified in such application.

     If the Trustee shall elect not to afford such applicants access to such
information, the Trustee shall, upon the written request of such applicants,
mail to each Holder whose name and address appear in the information preserved
at the time by the Trustee in accordance with the provisions of subsection (a)
of this Section 4.02 a copy of the form of proxy or other communication which is
specified in such request with reasonable promptness after a tender to the
Trustee of the material to be mailed and of payment, or provision for the
payment, of the reasonable expenses of mailing, unless within five days after
such tender, the Trustee shall mail to such applicants and file with the
Commission, together with a copy of the material to be mailed, a written
statement to the effect that, in the opinion of the Trustee, such mailing would
be contrary to the best interests of the Holders of all Securities or would be
in violation of applicable law. Such written statement shall specify the basis
of such opinion. If the Commission, after opportunity for a hearing upon the
objections specified in the written statement so filed, shall enter an order
refusing to sustain any of such objections or if, after the entry of an order
sustaining one or more of such objections, the Commission shall find, after
notice and opportunity for hearing, that all the objections so sustained have
been met and shall enter an order so declaring, the Trustee shall mail copies of
such material to all such Holders with reasonable promptness after the entry of
such order and the renewal of such tender; otherwise the Trustee shall be
relieved of any obligation or duty to such applicants respecting their
application.

     (c) Each and every Holder of Securities, by receiving and holding the same,
agrees with the Company and the Trustee that neither the Company nor the Trustee
nor any Paying Agent shall be held accountable by reason of the disclosure of
any such information as to the names and addresses of the Holders of Securities
in accordance with the provisions of subsection (b) of this Section 4.02,
regardless of the source from which such information was derived, and that the
Trustee shall not be held accountable by reason of mailing any material pursuant
to a request made under said subsection (b).

     SECTION 4.03. Reports of the Company and the Guarantor.


     The Company and the Guarantor covenant and agree:

     (a) to file with the Trustee, within 15 days after the date on which the
Company and the Guarantor are required to file the same with the Commission,
copies of the annual reports and of the information, documents and other reports
(or copies of such portions of any of the foregoing as the Commission may from
time to time by rules and regulations prescribe) which the Company and the
Guarantor may be required to file with the Commission pursuant to Section 13 or
Section 15(d) of the Exchange Act; or, if the Company or the Guarantor is not
required to file information, documents or reports pursuant to either of such
sections, then to file with the Trustee and the Commission, in accordance with
rules and regulations prescribed from time to time by the Commission, such of
the supplementary and periodic information, documents and reports which may be
required pursuant to Section 13 of the Exchange Act in respect of a security
listed and registered on a national securities exchange as may be prescribed
from time to time in such rules and regulations.

     (b) to file with the Trustee and the Commission, in accordance with the
rules and regulations prescribed from time to time by the Commission, such
additional information, documents and reports with respect to compliance by the
Company with the conditions and covenants provided for in this Indenture as may
be required from time to time by such rules and regulations.

     (c) to transmit by mail to all Holders of Securities, as the names and
addresses of such holders appear upon the Security Register, within 30 days
after the filing thereof with the Trustee, such summaries of any information,
documents and reports required to be filed by the Company pursuant to
subsections (a) and (b) of this Section 4.03 as may be required by rules and
regulations prescribed from time to time by the Commission.

     (d) to notify the Trustee when and as the Securities of any series become
admitted to trading on any national securities exchange.

     Delivery of such reports, information and documents to the Trustee is for
informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

     SECTION 4.04. Reports by the Trustee.

     (a) The Trustee shall transmit to Holders such reports concerning the
Trustee and its actions under this Indenture as may be required pursuant to the
Trust Indenture Act at the times and in the manner provided pursuant thereto. If
required by Section 313(a) of the Trust Indenture Act, the Trustee shall, not
later than June 30 in each 


                                       41
<PAGE>
 
year, commencing June 30, 1998, deliver to Holders a brief report, dated as of
such June 30, which complies with the provisions of such Section 313(a).

     (b) A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Trustee with each stock exchange, if any, upon which
the Securities are listed, with the Commission and with the Company. The Company
will promptly notify the Trustee when and if the Securities are listed on any
stock exchange.


                                    ARTICLE V

                       REMEDIES OF THE TRUSTEE AND HOLDERS
                               ON EVENT OF DEFAULT


     SECTION 5.01. Events of Default.

     One or more of the following events with respect to Securities of any
series which has occurred and is continuing shall constitute an Event of Default
hereunder with respect to such series:

     (a) failure to pay interest, if any, including any Additional Interest, on
any Security of such series within 60 days after the same becomes due and
payable (whether or not payment is prohibited by the provisions of Article
Fourteen hereof); provided, however, that a valid extension of the interest
payment period or deferral of interest payment by the Company as contemplated in
Section 2.17 of this Indenture shall not constitute a failure to pay interest
for this purpose; or

     (b) failure to pay the principal of or premium, if any, on any Security of
such series (whether or not payment is prohibited by the provisions of Article
Fourteen hereof) when due and payable; or

     (c) failure to perform or breach of any covenant or warranty of the Company
or the Guarantor in this Indenture (other than a covenant or warranty a default
in the performance of which or breach of which is elsewhere in this Section
specifically dealt with or which has expressly been included in this Indenture
solely for the benefit of one or more series of Securities other than such
series) for a period of 60 days after there has been given, by registered or
certified mail, to the Company or the Guarantor by the Trustee or to the Company
or the Guarantor and the Trustee by the Holders of at least 33% in aggregate
principal amount of the outstanding Securities of such series, a written notice
specifying such default or breach and requiring it to be remedied and stating
that such notice is a "Notice of Default" hereunder; or

     (d) the entry by a court having jurisdiction in the premises of (1) a
decree or order for relief in respect of the Company or the Guarantor in an
involuntary case or proceeding under any applicable Federal or state bankruptcy,
insolvency, reorganization or other similar law or (2) a decree or order
adjudging the Company or the Guarantor a bankrupt or insolvent, or approving as
properly filed a petition by one or more Persons other than the Company or the
Guarantor seeking reorganization, arrangement, adjustment or composition of or
in respect of the Company or the Guarantor 


                                       42
<PAGE>
 
under any applicable Federal or state law, or appointing a custodian, receiver,
liquidator, assignee, trustee, sequestrator or other similar official for the
Company or the Guarantor or for any substantial part of its property, or
ordering the winding-up or liquidation of its affairs, and any such decree or
order for relief or any such other decree or order shall have remain unstayed
and in effect for a period of 90 consecutive days; or

     (e) the commencement by the Company or the Guarantor of a voluntary case or
proceeding under any applicable Federal or state bankruptcy, insolvency,
reorganization or other similar law or of any other case or proceeding to be
adjudicated a bankrupt or insolvent, or the consent by it to the entry of a
decree or order for relief in respect of the Company or the Guarantor in a case
or proceeding under any applicable Federal or state bankruptcy, insolvency,
reorganization or other similar law or to the commencement of any bankruptcy or
insolvency case or proceeding against it, or the filing by it of a petition or
answer or consent seeking reorganization or relief under any applicable Federal
or state law, or the consent by it to the filing of such petition or to the
appointment of or taking possession by a custodian, receiver, liquidator,
assignee, trustee, sequestrator or similar official of the Company or the
Guarantor or of any substantial part of its property, or the making by it of an
assignment for the benefit of creditors, or the admission by it in writing of
its inability to pay its debts generally as they become due, or the
authorization of such action by the Board of Directors.

     (f) the Guarantee shall be held in a final judicial proceeding to be
unenforceable or invalid or shall cease for any reason to be in full force and
effect.

     (g) any other Event of Default specified with respect to the terms of the
Securities of such series as contemplated herein.

     If an Event of Default due to the default in payment of principal of, or
interest on, any series of Securities or due to the default in the performance
or breach of any other covenant or warranty of the Company or the Guarantor
applicable to the Securities of such series but not applicable to all
outstanding Securities shall have occurred and be continuing, either the Trustee
or the Holders of not less than 33% in aggregate principal amount of the
outstanding Securities of such series may then declare the principal of all
Securities of such series and interest accrued thereon to be due and payable
immediately (provided that the payment of principal and interest on such
Securities shall remain subordinated to the extent provided in Article XIV
hereof). If the Trustee or the Holders of not less than 33% in principal amount
of the Securities of such series fail to make such declaration, and the Trust
Securities issued by the Business Trust to which such series of Securities
relate are still outstanding, then the holders of not less than 33% in aggregate
liquidation preference of such series of Trust Securities may make such
declaration. If an Event of Default due to the default in the performance of any
other of the covenants or agreements herein applicable to all outstanding
Securities or an Event of Default specified in Section 5.01(d) or (e) shall have
occurred and be continuing, either the Trustee or the Holders of not less than
33% in aggregate principal amount of all Securities then outstanding (or Trust
Securities), considered as one class, and not the Holders of the Securities (or
Trust Securities) of any one of such series, may declare the principal of all
Securities and interest accrued thereon to be due and payable immediately

                                       43
<PAGE>
 
(provided that the payment of principal and interest on such Securities shall
remain subordinated to the extent provided in Article XIV).

     If an Event of Default shall occur and be continuing with respect to the
Securities of any series, the Property Trustee will have the right to declare
the principal of and premium, if any, and interest on such Securities 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 such Securities.

     At any time after such a declaration of acceleration with respect to
Securities of any series shall have been made and before a judgment or decree
for payment of the money due shall have been obtained by the Trustee as
hereinafter in this Article provided, the Event or Events of Default giving rise
to such declaration of acceleration shall, without further act, be deemed to
have been waived, and such declaration and its consequences shall, without
further act, be deemed to have been rescinded and annulled, if (a) the Company
or the Guarantor shall have paid or deposited with the Trustee a sum sufficient
to pay (1) all overdue interest on all Securities of such series, (2) the
principal of and premium, if any, on any Securities of such series which shall
have become due otherwise than by such declaration of acceleration and interest
thereon at the rate or rates prescribed therefor in such Securities, (3) to the
extent that payment of such interest is lawful, interest upon overdue interest,
if any, at the rate or rates prescribed therefor in such Securities, and (4) all
amounts due to the Trustee under Section 6.06, and (b) any other Event or Events
of Default with respect to Securities of such series, other than the non-payment
of the principal of Securities of such series which shall have become due solely
by such declaration of acceleration, shall have been cured or waived as provided
in Section 5.06.

     No such rescission shall affect any subsequent Event of Default or impair
any right consequent thereon. In case the Trustee or any Holder shall have
proceeded to enforce any right under this Indenture and such proceedings shall
have been discontinued or abandoned for any reason or shall have been determined
adversely to the Trustee, then and in every such case the Company, the
Guarantor, the Trustee and the Holders of the Securities shall be restored
respectively to their several positions and rights hereunder, and all rights,
remedies and powers of the Company, the Trustee and the Holders of the
Securities shall continue as though no such proceeding had been taken.

     SECTION 5.02. Payment of Securities on Default; Suit Therefor.

     If an Event of Default described in clause (a) or (b) of Section 5.01 shall
have occurred and be continuing, the Company shall, upon demand of the Trustee,
pay to it, for the benefit of the Holders of the Securities of the series with
respect to which such Event of Default shall have occurred, the whole amount
then due and payable on such Securities for principal and premium, if any, and
interest, if any, and, to the extent permitted by law, interest on premium, if
any, and on any overdue principal and interest, at the rate or rates prescribed
therefor in such Securities, and, in addition thereto, such further amount as
shall be sufficient to cover any amounts due to the Trustee under Section 6.06.




                                       44
<PAGE>
 
     If the Company shall fail to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon such Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon such Securities, wherever
situated.

     If an Event of Default with respect to Securities of any series shall have
occurred and be continuing, the Trustee may in its discretion proceed to protect
and enforce its rights and the rights of the Holders of Securities of such
series by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

     If an Event of Default shall have occurred and be continuing as to the
Securities of any series and if Trust Securities relating to such series of
Securities are outstanding, the Property Trustee holding such series of
Securities shall have the right to declare the principal of and interest on such
series of Securities to be immediately due and payable and to enforce its other
rights as a creditor with respect to such series of Securities.

     In case there shall be pending proceedings for the bankruptcy or for the
reorganization of the Company or any other obligor on the Securities under Title
11, United States Code, or any other applicable law, or in case a receiver or
trustee shall have been appointed for the property of the Company or such other
obligor, or in the case of any other similar judicial proceedings relative to
the Company or other obligor upon the Securities, or to the creditors or
property of the Company or such other obligor, the Trustee, irrespective of
whether the principal of the Securities shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand pursuant to the provisions of this Section 5.02,
shall be entitled and empowered, by intervention in such proceedings or
otherwise, to file and prove a claim or claims for the whole amount of
principal, premium, if any, and interest owing and unpaid in respect of the
Securities and, in case of any judicial proceedings, to file such proofs of
claim and other papers or documents as may be necessary or advisable in order to
have the claims of the Trustee (including any claim for all amounts payable
pursuant to Section 6.06 to the Trustee and each predecessor Trustee) and of the
Holders allowed in such judicial proceedings relative to the Company or any
other obligor on the Securities, or to the creditors or property of the Company
or such other obligor, unless prohibited by applicable law and regulations, to
vote on behalf of the holders of the Securities in any election of a trustee or
a standby trustee in arrangement, reorganization, liquidation or other
bankruptcy or insolvency proceedings or Person performing similar functions in
comparable proceedings, and to collect and receive any moneys or other property
payable or deliverable on any such claims, and to distribute the same after the
deduction of its charges and expenses; and any receiver, assignee or trustee in
bankruptcy or reorganization is hereby authorized by each of the 


                                       45
<PAGE>
 
Holders to make such payments to the Trustee, and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to
the Trustee such amounts as shall be sufficient to pay to the Trustee and each
predecessor Trustee all amounts payable pursuant to Section 6.06.

     Nothing herein contained shall be construed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

     All rights of action and of asserting claims under this Indenture, or under
any of the Securities, may be enforced by the Trustee without the possession of
any of the Securities, or the production thereof in any trial or other
proceeding relative thereto, and any such suit or proceeding instituted by the
Trustee shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall be for the ratable benefit of the Holders of the
Securities.

     In any proceedings brought by the Trustee (and also any proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the Holders
of the Securities, and it shall not be necessary to make any Holders of the
Securities parties to any such proceedings.

     SECTION 5.03. Application of Moneys Collected by Trustee.

     Any moneys collected by the Trustee with respect to a particular series of
Securities pursuant to this Article V shall be applied in the order following,
at the date or dates fixed by the Trustee for the distribution of such moneys,
upon presentation of the Securities in respect of which moneys have been
collected, and stamping thereon the payment, if only partially paid, and upon
surrender thereof if fully paid:

     First: To the payment of all amounts due the Trustee under Section 6.06,
including the costs and expenses of collection applicable to the Securities and
reasonable compensation to the Trustee, its agents, attorneys and counsel, and
of all other expenses and liabilities incurred, and all advances made, by the
Trustee except as a result of its negligence or bad faith;

     Second: To the payment of all Senior Debt of the Company if and to the
extent required by Article XIV;

     Third: In case the principal of the outstanding Securities in respect of
which moneys have been collected shall not have become due and be unpaid, to the
payment of the amounts then due and unpaid upon Securities for principal of (and
premium, if any) and interest on the Securities, in respect of which or for the
benefit of which money has been collected, ratably, without preference of
priority of any kind, according to the amounts due on such Securities for
principal (and premium, if any) and interest, respectively; and




                                       46
<PAGE>
 
     Fourth: To the Company or to whomsoever may be lawfully entitled to receive
the same or as a court of competent jurisdiction may direct.

     SECTION 5.04. Proceedings by Holders.

     No Holder shall have any right to institute any proceeding, judicial or
otherwise, with respect to this Indenture, or for the appointment of a receiver
or trustee, or for any other remedy hereunder, unless:

     (a) such Holder shall have previously given written notice to the Trustee
of a continuing Event of Default with respect to the Securities of such series;

     (b) the Holders of a majority in aggregate principal amount of the
Outstanding Securities of all series in respect of which an Event of Default
shall have occurred and be continuing, considered as one class, shall have made
written request to the Trustee to institute proceedings in respect of such Event
of Default in its own name as Trustee hereunder;

     (c) such Holder or Holders shall have offered to the Trustee reasonable
indemnity against the costs, expenses and liabilities to be incurred in
compliance with such request;

     (d) the Trustee for 60 days after its receipt of such notice, request and
offer of indemnity shall have failed to institute any such proceeding; and

     (e) no direction inconsistent with such written request shall have been
given to the Trustee during such 60-day period by the Holders of a majority in
aggregate principal amount of the Outstanding Securities of all series in
respect of which an Event of Default shall have occurred and be continuing,
considered as one class;


it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders or to obtain or to seek to obtain priority or preferences over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such
Holders.

     Notwithstanding any other provision in this Indenture, but subject to
Article XIV, the Holder of any Security shall have the right, which is absolute
and unconditional, to receive payment of the principal of and premium, if any,
and (subject to extension pursuant to Section 2.17) interest, if any, on such
Security on or after the same shall have become due and payable and to institute
suit for the enforcement of any such payment, and such rights shall not be
impaired without the consent of such Holder. So long as the Securities of any
series are held by a Business Trust, a registered holder of Trust Securities
issued by such Business Trust may institute a proceeding directly against the
Guarantor pursuant to the Guarantee, without first instituting a legal
proceeding directly against or requesting or directing that action be taken by
the Property Trustee of such Business Trust or any other Person, for enforcement
of payment to such registered


                                       47
<PAGE>
 
holder of principal of or interest on Securities of such series having a
principal amount equal to the aggregate stated liquidation amount of such Trust
Securities of such registered holder on or after the due dates therefor
specified or provided for in the Securities of such series.

     SECTION 5.05. Remedies Cumulative and Continuing.

     All powers and remedies given by this Article V to the Trustee or to the
Holders shall, to the extent permitted by law, be deemed cumulative and not
exclusive of any other powers and remedies available to the Trustee or the
holders of the Securities, by judicial proceedings or otherwise, to enforce the
performance or observance of the covenants and agreements contained in this
Indenture or otherwise established with respect to the Securities, and no delay
or omission of the Trustee or of any holder of any of the Securities to exercise
any right or power accruing upon any Event of Default occurring and continuing
as aforesaid shall impair any such right or power, or shall be construed to be a
waiver of any such default or an acquiescence therein; and, subject to the
provisions of Section 5.04, every power and remedy given by this Article V or by
law to the Trustee or to the Holders may be exercised from time to time, and as
often as shall be deemed expedient, by the Trustee or by the Holders.

     SECTION 5.06. Direction of Proceedings and Waiver of Defaults by Majority
of Holders.

     If an Event of Default shall have occurred and be continuing in respect of
a series of Securities, the Holders of a majority in principal amount of the
Outstanding Securities of such series shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee, or exercising any trust or power conferred on the Trustee, with respect
to the Securities of such series; provided, however, that if an Event of Default
shall have occurred and be continuing with respect to more than one series of
Securities, the Holders of a majority in aggregate principal amount of the
Outstanding Securities of all such series, considered as one class, shall have
the right to make such direction, and not the Holders of the Securities of any
one of such series; and provided, further, that

     (a) such direction shall not be in conflict with any rule of law or with
this Indenture, and could not involve the Trustee in personal liability, in
circumstances where indemnity would not, in the Trustee's sole discretion, be
adequate; and

     (b) the Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction.

     The Holders of a majority in principal amount of the Outstanding Securities
of any series may on behalf of the Holders of all the Securities of such series
waive any past default hereunder with respect to such series and its
consequences, except a default

     (a) in the payment of the principal of or premium, if any, or interest, if
any, on any Security of such series (unless such default has been cured and a
sum


                                       48
<PAGE>
 
sufficient to pay all matured installments of interest, principal and such other
amounts due otherwise that by acceleration has been deposited with the Trustee),
or

     (b) in respect of a covenant or provision hereof which under Section 9.02
cannot be modified or amended without the consent of the Holder of each
Outstanding Security of such series affected;

provided, however, that so long as a Business Trust is the beneficial owner of
the Securities or the Book-Entry Interests in Securities of any series, such
Business Trust may not waive compliance by the Company or the Guarantor with any
past default without the consent of a majority in aggregate liquidation
preference of the outstanding Trust Securities issued by such Business Trust
affected, obtained as provided in the Trust Agreement pertaining to such
Business Trust.

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

     SECTION 5.07. Undertaking to Pay Costs.

     All parties to this Indenture agree, and each Holder of any Security by his
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken or
omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees and
expenses, against any party litigant in such suit, having due regard to the
merits and good faith of the claims or defenses made by such party litigant; but
the provisions of this Section 5.07 shall not apply to any suit instituted by
the Trustee, to any suit instituted by any Holder, or group of Holders, holding
in the aggregate more than 10% in aggregate principal amount of the Securities
outstanding, or to any suit instituted by any Holder for the enforcement of the
payment of the principal of (or premium, if any) or interest on any Security
against the Company on or after the date the same shall have become due and
payable.


                                   ARTICLE VI

                             CONCERNING THE TRUSTEE


     SECTION 6.01. Certain Duties and Responsibilities.

     (a) Except during the continuance of a default with respect to the
Securities of any series,

          (1) the Trustee undertakes to perform, such duties and only such
     duties as are specifically set forth in this Indenture, and no implied
     covenants or obligations shall be read into this Indenture against the
     Trustee; and

                                       49
<PAGE>
 
          (2) in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture; but in
     the case of any such certificates or opinions which by any provision hereof
     are specifically required to be furnished to the Trustee, the Trustee shall
     examine the same to determine whether or not they conform to the
     requirements of this Indenture.

     (b) In case a default has occurred and is continuing, the Trustee shall
exercise such of the rights and powers vested in it by this Indenture, and use
the same degree of care and skill in their exercise, as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs.

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

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

          (2) no provision of this Indenture shall require the Trustee to spend
     or risk its own funds or otherwise incur any financial liability in the
     performance of any of its duties hereunder, or in the exercise of any of
     its rights or powers, if repayment of such funds or adequate indemnity
     against such risk or liability satisfactory to the Trustee has not been
     assured to it; and

          (3) the Trustee shall not be liable with respect to any action taken
     or omitted to be taken by it in good faith in accordance with the direction

     Securities of such series.

     (d) Whether or not therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section
6.01.

     SECTION 6.02. Notice of Defaults.

     Within 90 days after the occurrence of any default hereunder with respect
to the Securities of any series, the Trustee shall transmit by mail to all
Holders of Securities of such series notice of such default hereunder known to
the Trustee, unless such default shall have been cured or waived; provided,
however, that, except in the case of a default in the payment of the principal
of, premium, if any, or interest, if any, on any Security of such series or in
the payment of any sinking fund installment with respect to Securities of such

New York reasonably acceptable to the Company to conduct any activities which
the Trustee may be required under this Indenture to conduct in The City of New

report of condition so published. If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section 6.09, the Trustee
shall resign immediately in the manner and with the effect hereinafter specified
in this Article.

     SECTION 6.10. Resignation and Removal; Appointment of Successor Trustee.

     (a) No resignation or removal of the Trustee and no appointment of a

acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 6.11.

     (b) The Trustee may resign at any time with respect to the Securities of
one or more series by giving written notice thereof to the Company. If the
instrument


                                       53
<PAGE>
 
of acceptance by a successor Trustee required by Section 6.11 shall not have
been delivered to the Trustee within 30 days after the giving of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

     (c) The Trustee may be removed at any time with respect to the Securities
of any series by Act of the Holders of a majority in principal amount of the

Company.

     (d) If at any time:

          (1) the Trustee shall fail to comply with section 310(b) of the Trust
     Indenture Act pursuant to Section 6.08 with respect to any series of
     Securities after written request therefor by the Company or by any Holder
     who has been a bona fide holder of a Security for at least six months, or

          (2) the Trustee shall cease to be eligible under Section 6.09 and
     shall fail to resign after written request therefor by the Company or by
     any such Holder, or

          (3) the Trustee shall become incapable of acting or shall be adjudged
     a bankrupt or insolvent or a receiver of the Trustee or of its property
     shall be appointed or any public officer shall take charge or control of
     the Trustee or of its property or affairs for the purpose of
     rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee with respect to all Securities, or (ii) subject to Section 5.07, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.

     (e) If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Securities of one or more series, the Company, by a Board Resolution,
shall promptly appoint a successor Trustee or Trustees with respect to the
Securities of that or those series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all of
such series and that at any time there shall be only one Trustee with respect to
the Securities of any particular series) and shall comply with the applicable
requirements of Section 6.11. If no successor Trustee with respect to the
Securities of any series shall have been so appointed by the Company and
accepted appointment in the manner required by Section 6.11, any Holder who has
been a bona fide Holder of a Security of such series for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series.




                                       54
<PAGE>
 
     (f) The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series by mailing
written notice of such event by first-class mail, postage prepaid, to all
Holders of Securities of such series as their names and addresses appear in the
Security Register. Each notice shall include the name of the successor Trustee
with respect to the Securities of such series and the address of its corporate
trust office.

     SECTION 6.11. Acceptance of Appointment by Successor.

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

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


                                       55
<PAGE>
 
by such retiring Trustee hereunder with respect to the Securities of that or
those series to which the appointment of such successor Trustee relates.

     (c) Upon request of any such successor Trustee, the Company shall execute
any and all instruments for more fully and certainly vesting in and confirming
to such successor Trustee all such rights, powers and trusts referred to in
paragraph (a) or (b) of this Section 6.11, as the case may be.

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

     SECTION 6.12. Merger, Conversion, Consolidation or Succession to Business.

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

     SECTION 6.13. Preferential Collecting of Claims Against Company.

     (a) Subject to Subsection (b) of this Section 6.13, if the Trustee shall be
or shall become a creditor, directly or indirectly, secured or unsecured, of the
Company within three months prior to a default, as defined in Subsection (c) of
this Section 6.13, or subsequent to such a default, then, unless and until such
default shall be cured, the Trustee shall set apart and hold in a special
account for the benefit of the Trustee individually, the Holders of the
Securities and the holders of other indenture securities, as defined in
Subsection (c) of this Section 6.13:

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

          (2) all property received by the Trustee in respect of any claims as
     such creditor, either as security therefor, or in satisfaction or
     composition


                                       56
<PAGE>
 
     thereof, or otherwise, after the beginning of such three months' period, or
     an amount equal to the proceeds of any such property, if disposed of,
     subject, however, to the rights, if any, of the Company and its other
     creditors in such property or such proceeds.

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

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

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

          (C) to realize, for its own account, but only to extent of the claim
     hereinafter mentioned, upon any property held by it as security for any
     such claim, if such claim was created after the beginning of such three
     months' period and such property was received as security therefor
     simultaneously with the creation thereof, and if the Trustee shall sustain
     the burden of proving that at the time such property was so received the
     Trustee had no reasonable cause to believe that a default, as defined in
     Subsection (c) of this Section 6.13, would occur within three months; or

          (D) to receive payment on any claim referred to in paragraph (B) or
     (C), against the release of any property held as security for such claim as
     provided in paragraph (B) or (C) , as the case may be, to the extent of the
     fair value of such property.

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

     If the Trustee shall be required to account for the funds and property held
in such special account, the proceeds thereof shall be apportioned among the
Trustee, the Holders and the holders of other indenture securities in such
manner that the Trustee, the Holders and the holders of other indenture
securities realize, as a result of payments from such special account and
payments of dividends on claims filed against the Company in bankruptcy or
receivership or in proceedings for reorganization pursuant to the Federal

                                       57
<PAGE>
 
Bankruptcy Act or applicable State law or winding up or administration pursuant
to the insolvency laws of the Cayman Islands or the United Kingdom, as
applicable, the same percentage of their respective claims, figured before
crediting to the claim of the Trustee anything on account of the receipt by it
from the Company of the funds and property in such special account and before
crediting to the respective claims of the Trustee and the Holders and the
holders of other indenture securities dividends on claims filed against the
Company in bankruptcy or receivership or in proceedings for reorganization
pursuant to the Federal Bankruptcy Act or applicable State law or winding up or
administration pursuant to the insolvency laws of the Cayman Islands or the
United Kingdom, as applicable, but after crediting thereon receipts on account
of the indebtedness represented by their respective claims from all sources
other than from such dividends and from the funds and property so held in such
special account. As used in this paragraph, with respect to any claim, the term
"dividends" shall include any distribution with respect to such claim, in
bankruptcy or receivership or proceedings for reorganization pursuant to the
Federal Bankruptcy Act or applicable State law or winding up or administration
pursuant to the insolvency laws of the Cayman Islands or the United Kingdom, as
applicable, whether such distribution is made in cash, securities or other
property, but shall not include any such distribution with respect to the
secured portion, if any, of such claim.

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

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

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

     (b) There shall be excluded from the operation of Subsection (a) of this
Section 6.13 a creditor relationship arising from:

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

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


                                       58

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

          (4) an indebtedness created as a result of services rendered or
     premises rented; or an indebtedness created as a result of goods or
     securities sold in a cash transaction, as defined in Subsection (c) of this
     Section 6.13;

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

          (6) the acquisition, ownership, acceptance or negotiation of any
     drafts, bills of exchange, acceptances or obligations which fall within the
     classification of self-liquidating paper, as defined in Subsection (c) of
     this Section 6.13.

     (c) For the purposes of this Section 6.13 only:

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

          (2) the term "other indenture securities" means securities upon which
     the Company is an obligor (as defined in the Trust Indenture Act)
     outstanding under any other indenture (i) under which the Trustee is also
     trustee, (ii) which contains provisions substantially similar to the
     provisions of this Section 6.13, and (iii) under which a default exists at
     the time of the apportionment of the funds and property held in such
     special account;

          (3) the term "cash transaction" means any transaction in which full

     possession of, or a lien upon, the goods, wares or merchandise or the
     receivables or proceeds arising from the sale of the goods, wares or
     merchandise previously constituting the security, provided the security is
     received by the Trustee simultaneously with the creation of the creditor
     relationship with the Company arising from the making, drawing, negotiating
     or incurring of the draft, bill of exchange, acceptance or obligation;

     From time to time the Trustee, with the prior written approval of the
Company, may appoint one or more Authenticating Agents with respect to one or
more series of Securities with power to act on the Trustee's behalf and subject
to its direction in the authentication and delivery of Securities of such series
or in connection with transfers and exchanges under Sections 2.08, 2.09, 2.10,

shall be acceptable to the Company and shall at all times be a corporation
organized and doing business under the laws of the United States, any State
thereof or the District of Columbia, authorized under such laws to exercise

condition at least annually pursuant to law or the requirements of such
authority, then for the purposes of this Section 6.14 the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time an Authenticating Agent shall cease to be eligible in accordance with
the provisions of this Section 6.14, such Authenticating Agent shall resign
immediately in the manner and with the effect specified in this Section 6.14.

     Any corporation into which any Authenticating Agent may be merged or with
which it may be consolidated, or any corporation resulting from, any merger or
consolidation or to which any Authenticating Agent shall be a party, or any
corporation succeeding to the corporate trust business of any Authenticating
Agent, shall be the successor of the Authenticating Agent hereunder, if such
successor corporation is otherwise eligible under this Section 6.14, without the
execution or filing of any paper or any further act on the part of the parties
hereto or the Authenticating Agent or such successor corporation.

     An Authenticating Agent may resign at any time by giving written notice of
resignation to the Trustee and to the Company. The Trustee may at any time
terminate the agency of any Authenticating Agent by giving written notice of
termination to such Authenticating Agent and to the Company. Upon receiving such
a notice of resignation or upon such a termination, or in case at any time any
Authenticating Agent shall cease to be eligible under this Section 6.14, the
Trustee may appoint a successor Authenticating Agent with the prior written
approval of the Company and shall mail notice of such

appointment to all Holders of Securities of the series with respect to which
such Authenticating Agent will serve, as the names and addresses of such Holders
appear on the Security Register. Any successor Authenticating Agent, upon
acceptance of its appointment hereunder, shall become vested with all the
rights, powers and duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent. No successor Authenticating Agent
shall be appointed unless eligible under the provisions of this Section 6.14.

     The Trustee agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section 6.14 as may be
agreed in a separate writing among the Company, the Trustee and such
Authenticating Agent, and the Trustee shall be entitled to be reimbursed for
such payments pursuant to Section 6.07.

     If an appointment with respect to one or more series of Securities is made
pursuant to this Section 6.14, the Securities of such series may have endorsed
thereon, in addition to the Trustee's certificate of authentication, an
alternate certificate of authentication in the following form:

                                   ARTICLE VII

                             CONCERNING THE HOLDERS


     SECTION 7.01. Action by Holders.

     Whenever in this Indenture it is provided that the Holders of a specified
percentage in aggregate principal amount of the Securities of one or more, or
all, series may take any action (including the making of any demand or request,
the giving of any notice, consent or waiver or the taking of any other action)
the fact that at the time of taking any such action the Holders of such
specified percentage have joined therein may be evidenced (a) by any instrument
or any number of instruments of similar tenor executed by such Holders in person
or by agent or proxy appointed in writing, or (b) by the record of such Holders
of Securities voting in favor thereof at any meeting of such Holders duly called
and held in accordance with the provisions of Article VIII, or (c) by a
combination of such instrument or instruments and any such record of such a
meeting of such Holders.

     If the Company shall solicit from the Holders any request, demand,
authorization, direction, notice, consent, waiver or other action, the Company
may, at its option, as evidenced by an Officers' Certificate, fix in advance a
record date for the determination of Holders entitled to give such request,
demand, authorization, direction, notice, consent, waiver or other action, but
the Company shall have no obligation to do so. If such a record date is fixed,
such request, demand, authorization, direction, notice, consent, waiver or other
action may be given before or after the record date, but only the Holders of
record at the close of business on the record date shall be deemed to be Holders
for the purposes of determining whether Holders of the requisite proportion of

                                       62
<PAGE>
 
Outstanding Securities have authorized or agreed or consented to such request,
demand, authorization, direction, notice, consent, waiver or other action, and
for that purpose the Outstanding Securities shall be computed as of the record
date; provided, however, that no such authorization, agreement or consent by
such Holders on the record date shall be deemed effective unless it shall become
effective pursuant to the provisions of this Indenture not later than six months
after the record date.

     SECTION 7.02. Proof of Execution by Holders.

     Subject to the provisions of Sections 6.01, 6.02 and 8.05, proof of the
execution of any instrument by a Holder or his agent or proxy shall be
sufficient if made in accordance with such reasonable rules and regulations as
may be prescribed by the Trustee or in such manner as shall be satisfactory to
the Trustee. The ownership of Securities shall be proved by the Security
Register or by a certificate of the Security Registrar. The Trustee may require
such additional proof of any matter referred to in this Section as it shall deem
necessary.

     The record of any Holders' meeting shall be proved in the manner provided
in Section 8.06.

     SECTION 7.03. Who Are Deemed Absolute Owners.

     Prior to due presentment for registration of transfer of any Security, the
Company, the Trustee, any Authenticating Agent, any Paying Agent, any transfer
agent and any Security Registrar may deem the Person in whose name such Security
shall be registered upon the Security Register to be, and may treat him as, the
absolute owner of such Security (whether or not such Security shall be overdue)
for the purpose of receiving payment of or on account of the principal of and
premium, if any, and interest on such Security and for all other purposes; and
neither the Company nor the Trustee nor any Authenticating Agent nor any Paying
Agent nor any transfer agent nor any Security Registrar shall be affected by any
notice to the contrary. All such payments so made to any holder for the time
being or upon his order shall be valid, and, to the extent of the sum or sums so
paid, effectual to satisfy and discharge the liability for moneys payable upon
any such Security.

     SECTION 7.04. Securities Owned by Company Deemed Not Outstanding.

     In determining whether the holders of the requisite aggregate principal
amount of Securities of one or more, or all, series have concurred in any
direction, consent or waiver under this Indenture, Securities which are owned by
the Company or any other obligor on the Securities or by any Person directly or
indirectly controlling or controlled by or under direct or indirect common
control with the Company, except for the Securities owned by or on behalf of the
related Business Trust, or any other obligor on the Securities shall be
disregarded and deemed not to be outstanding for the purpose of any such
determination; provided that for the purposes of determining whether the Trustee
shall be protected in relying on any such direction, consent or waiver, only

                                       63
<PAGE>
 
Securities which a Responsible Officer of the Trustee actually knows are so
owned shall be so disregarded. Securities so owned which have been pledged in
good faith may be regarded as outstanding for the purposes of this Section 7.04
if the pledgee shall establish to the satisfaction of the Trustee the pledgee's
right to vote such Securities and that the pledgee is not the Company or any
such other obligor or Person directly or indirectly controlling or controlled by
or under direct or indirect common control with the Company or any such other
obligor. In the case of a dispute as to such right, any decision by the Trustee
taken upon the advice of counsel shall be full protection to the Trustee.

     SECTION 7.05. Revocation of Consents; Future Holders Bound.

     At any time prior to (but not after) the evidencing to the Trustee, as
provided in Section 7.01, of the taking of any action by the Holders of the
percentage in aggregate principal amount of the Securities of one or more, or
all, series specified in this Indenture in connection with such action, any
Holder of such a Security (or any Security issued in whole or in part in
exchange or substitution therefor) the serial number of which is shown by the
evidence to be included in the Securities the Holders of which have consented to
such action may, by filing written notice with the Trustee at its principal
office and upon proof of holding as provided in Section 7.02, revoke such action
so far as concerns such Security (or so far as concerns the principal amount
represented by any exchanged or substituted Security). Except as aforesaid, any
such action taken by the Holder of any Security shall be conclusive and binding
upon such Holder and upon all future Holders and owners of such Security, and of
any Security issued in exchange or substitution therefor, irrespective of
whether or not any notation in regard thereto is made upon such Security or any
Security issued in exchange or substitution therefor.


                                  ARTICLE VIII

     The Trustee may at any time call a meeting of Holders of one or more, or
all, series to take any action specified in Section 8.01, to be held at such
time and at such place in the Borough of Manhattan, The City of New York, as the
Trustee shall determine or, with the approval of the Company, at any other
place. Notice of every such meeting, setting forth the time and the place of
such meeting and in general terms the action proposed to be taken at such
meeting, shall be mailed to Holders of such Securities at their addresses as
they shall appear on the Securities Register. Such notice shall be mailed not
less than 20 nor more than 180 days prior to the date fixed for the meeting.

     SECTION 8.03. Call of Meetings by Company or Holders.

     In case at any time the Trustee shall have been requested to call a meeting

resolution of the Board of Directors, or by the Holders of at least 33% in
aggregate principal amount of all of such series, considered as one class, by
written request setting forth in reasonable detail the action proposed to be
taken at the meeting, and the Trustee shall not have mailed the notice of such
meeting within 20 days after receipt of such request, then the Company or such
Holders may determine the time and the place in the Borough of Manhattan, The
City of New York, for such meeting and may call such meeting to take any action
authorized in Section 8.01, by mailing notice thereof as provided in Section
8.02.

     SECTION 8.04. Qualifications for Voting.

     To be entitled to vote at any meeting of Holders of one or more, or all,
series, a Person shall be (a) a Holder of one or more outstanding Securities of

Company and its counsel.

     SECTION 8.05. Regulations.

     Notwithstanding any other provisions of this Indenture, the Trustee may
make such reasonable regulations as it may deem advisable for any meeting of
Holders, in regard to proof of the holding of such Securities and of the
appointment of proxies, and in regard to the appointment and duties of
inspectors of votes, the submission and examination of proxies, certificates and
other evidence of the right to vote, and such other matters concerning the
conduct of the meeting as it shall think fit.




                                       65
<PAGE>
 
     The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders as provided in Section 8.03, in which case the Company or
the Holders of the series calling the meeting, as the case may be, shall in like
manner appoint a temporary chairman. A permanent chairman and a permanent
secretary of the meeting shall be elected by majority vote of the meeting.

     Subject to the provisions of Section 8.04, at any meeting each Holder of
Securities of such series or proxy therefor shall be entitled to one vote for
each $25 principal amount of Securities held or represented by him; provided,
however, that no vote shall be cast or counted at any meeting in respect of any
Security challenged as not outstanding and ruled by the chairman of the meeting
to be not outstanding. The chairman of the meeting shall have no right to vote
other than by virtue of Securities held by him or instruments in writing as
aforesaid duly designating him as the person to vote on behalf of other Holders.
Any meeting of Holders duly called pursuant to the provisions of Section 8.02 or
8.03 may be adjourned from time to time by a majority in aggregate principal
amount of the outstanding Securities of all series represented at the meeting,
considered as one class, and the meeting may be held as so adjourned without

chairman of the meeting shall appoint two inspectors of votes who shall count
all votes cast at the meeting for or against any resolution and who shall make
and file with the secretary of the meeting their verified written reports in
triplicate of all votes cast at the meeting. A record in duplicate of the
proceedings of each meeting of Holders shall be prepared by the secretary of the
meeting and there shall be attached to said record the original reports of the
inspectors of votes on any vote by ballot taken thereat and affidavits by one or
more persons having knowledge of the facts setting forth a copy of the notice of
the meeting and showing that said notice was mailed as provided in Section 8.02.
The record shall show the serial numbers of the Securities voting in favor of or
against any resolution. The record shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one of the
duplicates shall be delivered to the Company and the other to the Trustee to be

Trustee, at any time and from time to time, may enter into one or more

     (c) to add any additional Events of Default with respect to all or any

hereto in any material respect, such change, elimination or addition shall
become effective with respect to such series only pursuant to the provisions of
Section 9.02 hereof or when no Security of such series remains Outstanding; or

<PAGE>
 
shall be necessary to provide for or facilitate the administration of the trusts

     (i) to provide for the procedures required to permit the Company to
utilize, at its option, a non-certificated system of registration for all, or

which may be defective or inconsistent with any other provision herein, or to
make any other changes to the provisions hereof or to add other provisions with
respect to matters or questions arising under this Indenture; provided that such
other changes or additions shall not adversely affect the interests of the
Holders of securities of any series in any material respect.

     The Trustee is hereby authorized to join with the Company and the Guarantor
in the execution of any supplemental indenture to effect such amendment, to make
any further appropriate agreements and stipulations which may be therein
contained and to accept the conveyance, transfer and assignment of any property
thereunder, but the Trustee shall not be obligated to, but may in its
discretion, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

     Any amendment to this Indenture authorized by the provisions of this
Section 9.01 may be executed by the Company, the Guarantor and the Trustee
without the consent of the Holders of any of the Securities at the time
outstanding, notwithstanding any of the provisions of Section 9.02.

     Without limiting the generality of the foregoing, if the Trust Indenture
Act as in effect at the date of the execution and delivery of this Indenture or
at any time thereafter shall be amended and (x) if any such amendment shall
require one or more changes to any provisions hereof or the inclusion herein of
any additional provisions, or shall by operation of law be deemed to effect such
changes or incorporate such provisions by reference or otherwise, this Indenture
shall be deemed to have been amended so as to conform to such amendment to the
Trust Indenture Act, and the Company, the Guarantor and the Trustee may, without
the consent of any Holders, enter into an indenture supplemental hereto to
effect or evidence such changes or additional provisions; or (y) if any such
amendment shall permit one or more changes to, or the elimination of, any
provisions hereof which, at the date of the execution and delivery hereof or at
any time thereafter, are required by the Trust Indenture Act to be contained
herein, this Indenture shall be deemed to have been amended to effect such
changes or elimination, and the 


                                       68
<PAGE>
 
Company, the Guarantor and the Trustee may, without the consent of any Holders,
enter into an indenture supplemental hereto to evidence such amendment hereof.

     SECTION 9.02. Supplemental Indentures With Consent of Holders.

     With the consent (evidenced as provided in Section 7.01) of the Holders of
a majority in aggregate principal amount of each series of the Securities then
outstanding under this Indenture that is directly affected thereby, the Company,
when authorized by a Board Resolution, the Guarantor and the Trustee may from
time to time and at any time modify this Indenture for the purpose of adding any
provisions to, or changing in any manner or eliminating any of the provisions
of, this Indenture or modifying in any manner the rights of the Holders of such
series of the Securities under this Indenture; provided, however, that no such
modification shall without the consent of the Holder of each Security of such
series then outstanding and affected thereby (i) change the Stated Maturity, if
any, of the principal of, or any installment of or interest on (except as
contemplated by Article XV), any series of Securities, or reduce the principal
amount thereof, or reduce the rate of interest thereon (or the amount of any
installment of interest thereon) or change the method of calculating such rate
or reduce any premium payable upon the redemption thereof, or change the coin or
currency (or other property), in which any Security or any premium or the
interest thereon is payable, or impair the right to institute suit for the
enforcement of any such payment, (ii) reduce the percentage of principal amount
of outstanding Securities of any series (or, if applicable, in liquidation
preference amount of any series of Trust Securities), the holders of which are
required to consent to any such modification of this 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 Guarantee,
(iv) modify the provisions of this Indenture with respect to the subordination
of the Securities or the Guarantee or (v) modify any of the provisions of this
Section 9.02, Section 5.06 or Section 3.11, except to increase the percentage in
principal amount required or to provide that certain other provisions of this
Indenture cannot be modified or waived without the consent of the holder of each
outstanding Security affected thereby; provided, however, that so long as any of
the Trust Securities of such series remain outstanding, if such modification
adversely affects the holders of such Trust Securities, such modification shall
not be effective, and no termination of the Indenture may occur, and no waiver
of any Event of Default or compliance with any covenant under this Indenture may
be effective, until the holders of a majority in aggregate liquidation
preference amount of such Trust Securities shall have given their prior consent,
obtained as provided in the Trust Agreement pertaining to such Business Trust,
to such modification, termination or waiver unless and until the principal of
the Securities of such series and all accrued and unpaid interest thereon have
been paid in full; provided, further, that if the prior consent of the holder of
each outstanding Security is required, such amendment shall not be effective
until each holder of the corresponding Trust Securities shall have so consented
to such amendment.

     Notwithstanding the foregoing, no amendment or modification may be made to
the Indenture if such amendment or modification would cause (i) the Company to
be classified as an association or a publicly traded partnership taxable as a
corporation for United States Federal income tax purposes or (ii) the Company or
the Guarantor to be


                                       69
<PAGE>
 
deemed an "investment company" which is required to register under the
Investment Company Act.

     Upon the request of the Company accompanied by a copy of a resolution of
the Board of Directors certified by an authorized signatory of the Company
authorizing the execution of any supplemental indenture affecting such
amendment, and upon the filing with the Trustee of evidence of the consent of
Holders as aforesaid, the Trustee shall join with the Company and the Guarantor
in the execution of such supplemental indenture unless such supplemental
indenture affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise, in which case the Trustee may in its discretion, but
shall not be obligated to, enter into such supplemental indenture.

     Promptly after the execution by the Company, the Guarantor and the Trustee
of any supplemental indenture pursuant to the provisions of this Section, the
Trustee shall transmit by mail, first class postage prepaid, a notice, prepared
by the Company, setting forth in general terms the substance of such
supplemental indenture, to the affected Holders as their names and addresses
appear upon the Security Register. Any failure of the Trustee to mail such
notice, or any defect therein, shall not, however, in any way impair or affect
the validity of any such supplemental indenture.

     It shall not be necessary for the consent of such Holders under this
Section 9.02 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such consent shall approve the
substance thereof.

     SECTION 9.03. Compliance with Trust Indenture Act; Effect of Supplemental
Indentures.

     Any supplemental indenture executed pursuant to the provisions of this
Article IX shall comply with the Trust Indenture Act. Upon the execution of any
supplemental indenture pursuant to the provisions of this Article IX, this
Indenture shall be and be deemed to be modified and amended in accordance
therewith and the respective rights, limitations of rights, obligations, duties
and immunities under this Indenture of the Trustee, the Company, the Guarantor
and the holders of Securities shall thereafter be determined, exercised and
enforced hereunder subject in all respects to such modifications and amendments
and all the terms and conditions of any such supplemental indenture shall be and
be deemed to be part of the terms and conditions of this Indenture for any and
all purposes.

     SECTION 9.04. Notation on Securities.

     Securities of any series authenticated and delivered after the execution of
any supplemental indenture affecting such series pursuant to the provisions of
this Article IX may bear a notation in form approved by the Trustee as to any
matter provided for in such supplemental indenture. If the Company or the
Trustee shall so determine, new Securities so modified as to conform, in the
opinion of the Trustee and the Board of Directors, to any modification of this
Indenture contained in any such supplemental 


                                       70
<PAGE>
 
indenture may be prepared and executed by the Company, the Guarantor,
authenticated by the Trustee or the Authenticating Agent and delivered in
exchange for such Securities then outstanding.

     SECTION 9.05. Evidence of Compliance of Supplemental Indenture to be
Furnished Trustee.

     The Trustee, subject to the provisions of Sections 6.01 and 6.02, may
receive an Officers' Certificate and an Opinion of Counsel as conclusive
evidence that any supplemental indenture executed pursuant to this Article is
authorized or permitted by, and conforms to, the terms of this Article and that
it is proper for the Trustee under the provisions of this Article to join in the
execution thereof.

                           SALE, CONVEYANCE AND LEASE


     SECTION 10.01. Company and Guarantor May Consolidate, etc., on Certain
Terms.

     Neither the Company nor the Guarantor shall consolidate with or merge into
any other corporation, or convey or otherwise transfer or lease its properties
and assets substantially as an entirety to any Person, unless (a) the
corporation formed by such consolidation or into which the Company or the
Guarantor is merged or the Person which acquires by conveyance or transfer, or
which leases, the properties and assets of the Company or the Guarantor
substantially as an entirety (a "successor corporation") shall expressly assume,
by an indenture supplemental hereto, executed and delivered to the Trustee, the
due and punctual payment of the principal of and premium, if any, and interest,
if any, on all outstanding Securities and the performance of every covenant of
this Indenture on the part of the Company or the Guarantor, as the case may be,
to be performed or observed, (b) immediately after giving effect to such
transaction, no Event of Default, and no event which, after notice or lapse of
time or both, would become an Event of Default, shall have occurred and be
continuing (c) the Company or Guarantor, as the case may be, shall have
delivered to the Trustee an Officers' Certificate and an Opinion of Counsel,
each stating that such consolidation, merger, conveyance, or other transfer or
lease and such supplemental indenture comply with this Article and that all
conditions precedent herein provided for relating to such transactions have been
complied with and (d), solely, with respect to the Company, the successor
corporation to the Company will be treated as a partnership and not as an
association or publicly traded partnership taxable as a corporation for United
States Federal income tax purposes.

     SECTION 10.02. Successor Corporation Substituted.

     Upon any consolidation by the Company or the Guarantor with or merger by
the Company or the Guarantor into any other corporation or any conveyance,
transfer, lease or other disposition of the properties and assets of the Company
or the Guarantor 


                                       71

substantially as an entirety in accordance with Section 10.01, the successor
corporation formed by such consolidation or into which the Company or the
Guarantor is merged or to which such conveyance, transfer or lease is made shall
succeed to, and be substituted for, and may exercise every right and power of,
the Company or the Guarantor under this Indenture with the same effect as if
such successor corporation had been named as the Company or the Guarantor
herein, and thereafter the predecessor corporation shall be relieved of all
obligations and covenants under this Indenture and the Securities.

     SECTION 10.03. Withholding.

     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 Securities, such additional amounts, under the
same circumstances and subject to the same limitations as are specified for
"Gross-Up Taxes" as is set forth in Section 3.12 hereof, 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
Securities under the same circumstances and subject to the same limitations as
are set forth in Section 13.02 hereof, 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.

                           SATISFACTION AND DISCHARGE


     SECTION 11.01. Satisfaction and Discharge of Securities.

     Any Security or Securities, or any portion of the principal amount thereof,
shall be deemed to have been paid for all purposes of this Indenture, and the
entire indebtedness of the Company in respect thereof shall be deemed to have
been satisfied and discharged, if there shall have been irrevocably deposited
with the Trustee or any Paying Agent (other than the Company), in trust:

     (a) money in an amount which shall be sufficient, or

     (b) in the case of a deposit made prior to the Maturity of such Securities
or portions thereof, Government Obligations, which shall 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 Trustee or such Paying Agent, shall
be sufficient, or

                                       72
<PAGE>
 
     (c) a combination of (a) or (b) which shall be sufficient, to pay when due
the principal of and premium, if any, and to pay when due the principal of and
premium, if any, and interest, if any, due and to become due on such Securities
or portions thereof on or prior to Maturity; provided, however, that in the case
of the provision for payment or redemption of less than all the Securities of
any series, such Securities or portions thereof shall have been selected by the
Security Registrar as provided herein and, in the case of a redemption, the
notice requisite to the validity of such redemption shall have been given or
irrevocable authority shall have been given by the Company to the Trustee to
give such notice, under arrangements satisfactory to the Trustee; and provided,
further, that the Company shall have delivered to the Trustee and such Paying
Agent:

          (x) if such deposit shall have been made prior to the Maturity of such
     Securities, a Company Order stating that the money and Government
     Obligations deposited in accordance with this Section shall be held in
     trust, as provided in Section 11.03; and

          (y) if Government Obligations shall have been deposited, an Opinion of
     Counsel that the obligations so deposited constitute Government Obligations
     and do not contain provisions permitting the redemption or other prepayment
     at the option of the issuer thereof, and an opinion of an independent
     public accountant of nationally recognized standing, selected by the
     Company, to the effect that the requirements set forth in clause (b) above
     have been satisfied; and

          (z) if such deposit shall have been made prior to the Maturity of such
     Securities, an Officer's Certificate stating the Company's intention that,
     upon delivery of such Officer's Certificate, its indebtedness in respect of
     such Securities or portions thereof will have been satisfied and discharged
     as contemplated in this Section.

     Upon the deposit of money or Government Obligations, or both, in accordance
with this Section, together with the documents required by clauses (x), (y) and
(z) above, the Trustee shall, upon receipt of a Company Request, acknowledge in
writing that the Security or Securities or portions thereof with respect to
which such deposit was made are deemed to have been paid for all purposes of
this Indenture and that the entire indebtedness of the Company in respect
thereof has been satisfied and discharged as contemplated in this Section. In
the event that all of the conditions set forth in the preceding paragraph shall
have been satisfied in respect of any Securities or portions thereof except
that, for any reason, the Officer's Certificate specified in clause (z), if
required, shall not have been delivered, such Securities or portions thereof
shall nevertheless be deemed to have been paid for all purposes of this
Indenture, and the Holders of such Securities or portions thereof shall
nevertheless be no longer entitled to the benefits of this Indenture or of any
of the covenants of the Company under Article III (except the covenants
contained in Sections 3.01 and 3.02) or any other covenants made in respect of
such Securities or portions thereof as contemplated by Section 2.05, but the
indebtedness of the Company in respect of such Securities or portions thereof
shall not be 


                                       73
<PAGE>
 
deemed to have been satisfied and discharged prior to Maturity for any other
purpose, and the Holders of such Securities or portions thereof shall continue
to be entitled to look to the Company for payment of the indebtedness
represented thereby; and, upon Company Request, the Trustee shall acknowledge in
writing that such Securities or portions thereof are deemed to have been paid
for all purposes of this Indenture.

     If payment at Stated Maturity of less than all of the Securities of any
series is to be provided for in the manner and with the effect provided in this
Section, the Security Registrar shall select such Securities, or portions of
principal amount thereof, in the manner specified by Section 13.05 for selection
for redemption of less than all the Securities of a series.

     In the event that Securities which shall be deemed to have been paid for
purposes of this Indenture, and, if such is the case, in respect of which the
Company's indebtedness shall have been satisfied and discharged, all as provided
in this Section do not mature and are not to be redeemed within the 60-day
period commencing with the date of the deposit of moneys or Government
Obligations, as aforesaid, the Company shall, as promptly as practicable, give a
notice, in the same manner as a notice of redemption with respect to such
Securities, to the Holders of such securities to the effect that such deposit
has been made and the effect thereof. Notwithstanding that any Securities shall
be deemed to have been paid for purposes of this Indenture, as aforesaid, the
obligations of the Company and the Trustee in respect of such Securities under
Sections 2.09, 2.10, 2.11, 3.02, 3.03, 6.07, 6.14, 13.03, 16.03 (as to notice of
redemption), and this Article XI shall survive.

     The Company shall pay, and shall indemnify the Trustee or any Paying Agent
with which Government Obligations shall have been deposited as provided in this
Section against, any tax, fee or other charge imposed on or assessed against
such Government Obligations or the principal or interest received in respect of
such Government Obligations, including, but not limited to, any such tax payable
by any entity deemed, for tax purposes, to have been created as a result of such
deposit.

     Anything herein to the contrary notwithstanding, (a) if, at any time after
a Security would be deemed to have been paid for purposes of this Indenture,
and, if such is the case, the Company's indebtedness in respect thereof would be
deemed to have been satisfied or discharged, pursuant to this Section (without
regard to the provisions of this paragraph), the Trustee or any Paying Agent, as
the case may be, shall be required to return the money or Government
Obligations, or combination thereof, deposited with it as aforesaid to the
Company or its representative under any applicable Federal or State bankruptcy,
insolvency or other similar law, such Security shall thereupon be deemed
retroactively not to have been paid and any satisfaction and discharge of the
Company's indebtedness in respect thereof shall retroactively be deemed not to
have been effected, and such Security shall be deemed to remain Outstanding and
(b) any satisfaction and discharge of the Company's indebtedness in respect of
any Security shall be subject to the provisions of the last paragraph of Section
3.03.

     SECTION 11.02. Satisfaction and Discharge of Indenture.

     This Indenture shall upon Company Request cease to be of further effect
(except as hereinafter expressly provided), and the Trustee, at the expense of
the Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when

          (a) no Securities remain Outstanding hereunder; and

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

     provided, however, that if, in accordance with the last paragraph of
     Section 11.01, any Security, previously deemed to have been paid for
     purposes of this Indenture, shall be deemed retroactively not to have been
     so paid, this Indenture shall thereupon be deemed retroactively not to have
     been satisfied and discharged, as aforesaid, and to remain in full force
     and effect, and the Company shall execute and deliver such instruments as
     the Trustee shall reasonably request to evidence and acknowledge the same.

     Notwithstanding the satisfaction and discharge of this Indenture as
aforesaid, the obligations of the Company and the Trustee under Sections 2.09,
2.10, 2.11, 3.02, 3.03, 6.07, 6.14, 13.03, 16.03 (as to notice of redemption),
and this Article XI shall survive.

     Upon satisfaction and discharge of this Indenture as provided in this
Section, the Trustee shall assign, transfer and turn over to the Company,
subject to the lien provided by Section 6.07, any and all money, securities and
other property then held by the Trustee for the benefit of the Holders of the
Securities other than money and Government Obligations held by the Trustee
pursuant to Section 11.03.

     SECTION 11.03. Application of Trust Money.

     Neither the Government Obligations nor the money deposited pursuant to
Section 11.01, nor the principal or interest payments on any such Government
Obligations, shall be withdrawn or used for any purpose other than, and shall be
held in trust for, the payment of the principal of and premium, if any, and
interest, if any, on the Securities or portions of principal amount thereof in
respect of which such deposit was made, all subject, however, to the provisions
of Section 3.03; provided, however, that, so long as there shall not have
occurred and be continuing an Event of Default, any cash received from such
principal or interest payments on such Government Obligations, if not then
needed for such purpose, shall, to the extent practicable, be invested upon
Company Request and upon receipt of the documents referred to in clause (y) of
Section 11.01 in Government Obligations of the type described in clause (b) in
the first paragraph of Section 11.01 maturing at such times and in such amounts
as shall be sufficient together with any other moneys and the principal of and
interest on any other Government Obligations then held by the Trustee to pay
when due the principal of and premium, if any, and interest, if any, due and to
become due on such Securities or portions thereof on 


                                       75
<PAGE>
 
and prior to the Maturity thereof, and interest earned from such reinvestment
shall be paid over to the Company as received, free and clear of any trust, lien
or pledge under this Indenture except the lien provided by Section 6.07; and
provided, further, that, so long as there shall not have occurred and be
continuing an Event of Default, any moneys held in accordance with this Section
on the Maturity of all such Securities in excess of the amount required to pay
the principal of and premium, if any, and interest, if any, then due on such
Securities shall be paid over to the Company free and clear of any trust, lien
or pledge under this Indenture except the lien provided by Section 6.07; and
provided, further, that if an Event of Default shall have occurred and be
continuing, moneys to be paid over to the Company pursuant to this Section shall
be held until such Event of Default shall have been waived or cured.


                                   ARTICLE XII

                    IMMUNITY OF INCORPORATORS, STOCKHOLDERS,
                             OFFICERS AND DIRECTORS


     SECTION 12.01. Indenture and Securities Solely Corporate Obligations.

     No recourse for the payment of the principal of or premium, if any, or
interest on any Security, or for any claim based thereon or otherwise in respect
thereof, and no recourse under or upon any obligation, covenant or agreement of
the Company or the Guarantor in this Indenture, or in any Security, or because
of the creation of any indebtedness represented thereby, shall be had against
any incorporator, stockholder, officer or director, as such, past, present or
future, of the Company or the Guarantor or of any successor Person to the
Company or the Guarantor, either directly or through the Company or any
successor Person to the Company or the Guarantor, whether by virtue of any
constitution, statute or rule of law, or by the enforcement of any assessment or
penalty or otherwise; it being expressly understood that all such liability is
hereby expressly waived and released as a condition of, and as a consideration
for, the execution of this Indenture and the issue of the Securities.

                  SECTION 13.01.    Applicability of Article.


     Securities of any series which are redeemable before their Stated Maturity
shall be redeemable in accordance with their terms and (except as otherwise
specified in or contemplated by Section 2.05 for Securities of any series) in
accordance with this Article XIII.

     SECTION 13.02. Optional Tax Redemption.

     If (a) the Company or Yorkshire Group satisfies the Trustee prior to the
giving of a notice as provided below that it has or will become obligated to pay

                                       76
<PAGE>
 
Additional Amounts with respect to the Securities of any series as a result of
either (x) any change in, or amendment to, the laws or regulations of the 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 the prospectus for the Trust Securities or (y)
the issuance of Definitive Securities pursuant to either (i) in the event of the
occurrence and continuance of an Event of Default with respect to such
Securities, a written request from the Book-Entry Depositary upon instructions
from owners of interest representing a majority in outstanding principal amount
of the certificateless depository interests in the Global Security or Securities
that such Securities be exchanged for one or more Definitive Securities, (ii)
the unwillingness or inability of DTC to continue to hold the certificateless
depository interests in the Global Security or Securities or DTC's ceasing to be
a "clearing agency" registered under the Exchange Act and, in either case, a
successor is not appointed by the Company within 120 days, or (iii) the
unwillingness or inability of the Book-Entry Depositary to continue to serve as
the book-entry depository with respect to the Global Security or Securities and
a successor is not appointed by the Company within 120 days and (b) such
obligation cannot be avoided by the Company or Yorkshire Group taking reasonable
measures available to it, then the Company shall have the right, at its option,
upon not less than 30 days nor more than 60 days' written notice to the Holders
of such series, to redeem such Securities, in whole but not in part, at the
Redemption Price plus accrued and unpaid interest thereon, and Additional
Amounts, if any, provided that no such notice of redemption shall be given
earlier than 90 days prior to the earliest date on which the Guarantor or the
Company would be obligated to pay such Additional Amounts were a payment in
respect of such Securities then due. Prior to the publication of any notice of
redemption pursuant to this paragraph, the Company shall deliver to the Trustee
a certificate signed by a director of the Company stating that the obligation
referred to in (a) above cannot be avoided by Yorkshire Group or the Company
taking reasonable measures available to it, and the Trustee shall accept such
certificate as sufficient evidence of the condition precedent set out in (b)
above, in which event it shall be conclusive and binding on the Holders.

     SECTION 13.03. Notice of Redemption; Selection of Securities.

     In case the Company shall desire to exercise the right to redeem all, or,
as the case may be, any part of the Securities of any series in accordance with
their terms, it shall fix a date for redemption and shall mail a notice of such
redemption at least 30 and not more than 60 days prior to the date fixed for
redemption to the Holders of such Securities so to be redeemed as a whole or in
part at their last addresses as the same appear on the Security Register. Such
mailing shall be by first class mail. The notice if mailed in the manner herein
provided shall be conclusively presumed to have been duly given, whether or not
the Holder receives such notice. In any case, failure to give such notice by
mail or any defect in the notice to the holder of any Security designated for
redemption as a whole or in part shall not affect the validity of the
proceedings for the redemption of any other Security.

     Each such notice of redemption shall specify the CUSIP number of the
Securities to be redeemed, the date fixed for redemption, the redemption price
at which


                                       77
<PAGE>
 
the Securities are to be redeemed (or the method by which such redemption price
is to be calculated), the place or places of payment, that payment will be made
upon presentation and surrender of the Securities, that interest accrued to the
date fixed for redemption will be paid as specified in said notice, that the
redemption is for a sinking or other fund, if such is the case, and that on and
after said date interest thereon or on the portions thereof to be redeemed will
cease to accrue. If less than all the Securities of a series are to be redeemed
the notice of redemption shall specify the numbers of the Securities to be
redeemed. In case any Security is to be redeemed in part only, the notice of
redemption shall state the portion of the principal amount thereof to be
redeemed and shall state that on and after the date fixed for redemption, upon
surrender of such Security, a new Security or Securities in principal amount
equal to the unredeemed portion thereof will be issued.

     The Redemption Price shall be paid prior to 12:00 noon, New York City time,
on the redemption date specified in the notice of redemption given as provided
in this Section, or such earlier time as the Company determines; provided that,
prior to 10:00 a.m., New York City time, on such date of redemption, the Company
shall deposit with the Trustee or with one or more Paying Agents an amount of
money sufficient to redeem all the Securities so called for redemption at the
appropriate Redemption Price, together with accrued interest to the date fixed
for redemption.

     The Company will give the Trustee notice in writing not less than 45 days
prior to the redemption date as to the aggregate principal amount of Securities
of such series to be redeemed and the Trustee shall select, in such manner as in
its sole discretion it shall deem appropriate and fair, the Securities or
portions thereof (in integral multiples of $25, except as otherwise set forth in
the applicable form of Security) to be redeemed.

     SECTION 13.04. Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued and
unpaid interest) such Securities shall cease to bear interest. Upon surrender of
any such Security for redemption in accordance with said notice, and Security
shall be paid by the Company at the Redemption Price, together with accrued and
unpaid interest to the Redemption Date; provided, however, that installments of
interest whose Stated Maturity is on or prior to the Redemption Date shall be
payable to the Holders of such Securities, or one or more Predecessor
Securities, and in the case of the Registered Securities, registered as such at
the close of business on the relevant Record Dates according to their terms and
the provisions of Section 2.11.

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



                                       78
<PAGE>
 
     SECTION 13.05. Securities Redeemed in Part.

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

                                   ARTICLE XIV

                           SUBORDINATION OF SECURITIES


     SECTION 14.01. Agreement to Subordinate.

     The Company covenants and agrees, and each Holder of Securities of each
series issued hereunder likewise covenants and agrees, that the Securities shall
be issued subject to the provisions of this Article XIV; and each Holder of the
Securities of each series, whether upon original issue or upon transfer or
assignment thereof, accepts and agrees to be bound by such provisions.

     The payment by the Company of the principal of and premium, if any, and
interest on all Securities issued hereunder shall, to the extent and in the
manner hereinafter set forth, be subordinated and junior in right of payment to
the prior payment in full of all amounts with respect to Senior Debt, whether
outstanding at the date of this Indenture or thereafter incurred.

     No provision of this Article XIV shall prevent the occurrence of any
Default or Event of Default hereunder.

     SECTION 14.02. Default on Senior Debt.

     In the event and during the continuation of (1) any default in any payment
of principal, premium, interest or any other payment with respect to any Senior
Debt, or (2) an event of default with respect to any Senior Debt resulting in
the declaration of acceleration thereof which remains uncured, then, in either
case, no payments with respect to the principal of, premium, if any, or
interest, if any, on any Securities shall be made.

     In the event of the declaration of acceleration of any Securities of any
series, the holders of all Senior Debt outstanding at the time of such
declaration shall be entitled to receive payment in full of all amounts due in
respect of such Senior Debt


                                       79
<PAGE>
 
(including any amounts due upon such declaration) before the Holders of
Securities will be entitled to receive any payment upon the principal of,
premium, if any, or interest, if any, on any of the Securities.

     In the event that, notwithstanding the foregoing, any payment shall be
received by the Trustee when such payment is prohibited by the preceding
paragraphs of this Section 14.02, such payment shall be held in trust for the
benefit of, and shall be paid over or delivered to, the holders of Senior Debt
or their respective representatives, or to the trustee or trustees under any
indenture pursuant to which any of such Senior Debt may have been issued, as
their respective interests may appear, but only to the extent of the amounts due
in respect of such Senior Debt and only to the extent that the holders of the
Senior Debt (or their representative or representatives or a trustee) notify the
Trustee in writing, within 90 days of such payment, of the amounts then due and
owing on such Senior Debt and only the amounts specified in such notice to the
Trustee shall be paid to the holders of such Senior Debt.

     SECTION 14.03. Liquidation; Dissolution; Bankruptcy.

     Upon any payment by the Company or distribution of assets of the Company of
any kind or character, whether in cash, property or securities, to creditors
upon any liquidation, dissolution, winding-up, reorganization, assignment for
the benefit of creditors, or marshaling of assets of the Company, whether
voluntary or involuntary or any bankruptcy, insolvency, debt restructuring or
similar proceedings in connection with any insolvency or bankruptcy proceeding
of the Company, the holders of Senior Debt of the Company shall first be
entitled to receive payment in full of principal of, premium, if any, and
interest, if any, on such Senior Debt before the Holders of Securities will be
entitled to receive or retain any payment in respect of the principal of,
premium, if any, or interest, if any, on the Securities; and upon any such
dissolution or winding-up or liquidation or reorganization, any payment by the
Company, or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, to which the Holders or the Trustee
would be entitled to receive from the Company, except for the provisions of this
Article XIV, shall be paid by the Company or by any receiver, trustee in
bankruptcy, liquidating trustee, agent or other Person making such payment or
distribution, or by the Holders or by the Trustee under this Indenture if
received by them or it, directly to the holders of Senior Debt of the Company
(pro rata to such holders on the basis of the respective amounts of Senior Debt
held by such holders, as calculated by the Company) or their representative or
representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing such Senior Debt may have been issued, as their
respective interests may appear, to the extent necessary to pay such Senior Debt
in full, in money or money's worth, after giving effect to any concurrent
payment or distribution to or for the holders of such Senior Debt, before any
payment or distribution is made to the Holders or to the Trustee.

     In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, prohibited by the foregoing, shall be received by the
Trustee before all Senior Debt is paid in full, or provision is made for such
payment in money in

accordance with its terms, such payment or distribution shall be held in trust
for the benefit of and shall be paid over or delivered to the holders of such
Senior Debt or their representative or representatives, or to the trustee or
trustees under any indenture pursuant to which any instruments evidencing such
Senior Debt may have been issued, and their respective interests may appear, as
calculated by the Company, for application to the payment of all Senior Debt
remaining unpaid to the extent necessary to pay such Senior Debt in full in
money in accordance with its terms, after giving effect to any concurrent
payment or distribution to or for the benefit of the holders of such Senior
Debt.

     For purposes of this Article XIV, the words "cash, property or securities"
shall not be deemed to include shares of stock of the Company as reorganized or
readjusted, or securities of the Company or any other corporation provided for
by a plan of reorganization or readjustment, the payment of which is
subordinated at least to the extent provided in this Article XIV with respect to
the Securities to the payment of Senior Debt that may at the time be
outstanding, provided that (i) such Senior Debt is assumed by the new
corporation, if any, resulting from any such reorganization or readjustment, and
(ii) the rights of the holders of such Senior Debt are not, without the consent
of such holders, altered by such reorganization or readjustment. The
consolidation of the Company with, or the merger of the Company into, another
Person or the liquidation or dissolution of the Company following the sale,
conveyance, transfer or lease of its property as an entirety, or substantially
as an entirety, to another Person upon the terms and conditions provided for in
Article X of this Indenture shall not be deemed a dissolution, winding-up,
liquidation or reorganization for the purposes of this Section 14.03 if such
other Person shall, as a part of such consolidation, merger, sale, conveyance,
transfer or lease, comply with the conditions stated in Article X of this
Indenture. Nothing in Section 14.02 or in this Section 14.03 shall apply to
claims of, or payments to, the Trustee under or pursuant to Section 6.06 of this
Indenture.

     SECTION 14.04. Subrogation.

     Subject to the payment in full of all amounts due in respect of Senior
Debt, the rights of the Holders shall be subrogated to the rights of the holders
of such Senior Debt to receive payments or distributions of cash, property or
securities of the Company, as the case may be, applicable to such Senior Debt
until the principal of (and premium, if any) and interest on the Securities
shall be paid in full; and, for the purposes of such subrogation, no payments or
distributions to the holders of such Senior Debt of any cash, property or
securities to which the Holders or the Trustee would be entitled except for the
provisions of this Article XIV, and no payment over pursuant to the provisions
of this Article XIV to or for the benefit of the holders of such Senior Debt by
Holders or the Trustee, shall, as between the Company, its creditors other than
holders of Senior Debt of the Company, and the Holders of the Securities, be
deemed to be a payment by the Company to or on account of such Senior Debt. It
is understood that the provisions of this Article XIV are and are intended
solely for the purposes of defining the relative rights of the Holders of the
Securities, on the one hand, and the holders of such Senior Debt, on the other
hand.

     Nothing contained in this Article XIV or elsewhere in this Indenture or in
the Securities is intended to or shall impair, as between the Company, its
creditors other than the holders of Senior Debt of the Company, and the Holders
of the Securities, the obligation of the Company, which is absolute and
unconditional, to pay to the Holders of the Securities the principal of (and
premium, if any) and interest on the Securities as and when the same shall
become due and payable in accordance with their terms, or is intended to or
shall affect the relative rights of the Holders of the Securities and creditors
of the Company, as the case may be, other than the holders of Senior Debt of the
Company, as the case may be, nor shall anything herein or therein prevent the
Trustee or the Holder of any Security from exercising all remedies otherwise
permitted by applicable law upon default under this Indenture, subject to the
rights, if any, under this Article XIV of the holders of such Senior Debt in
respect of cash, property or securities of the Company, as the case may be,
received upon the exercise of any such remedy.

     Upon any payment or distribution of assets of the Company referred to in
this Article XIV, the Trustee, subject to the provisions of Article VI of this
Indenture, and the Holders shall be entitled to conclusively rely upon any order
or decree made by any court of competent jurisdiction in which such dissolution,
winding-up, liquidation or reorganization proceedings are pending, or a
certificate of the receiver, trustee in bankruptcy, liquidation trustee, agent
or other Person making such payment or distribution, delivered to the Trustee or
to the Holders, for the purposes of ascertaining the Persons entitled to
participate in such distribution, the holders of Senior Debt and other
indebtedness of the Company, as the case may be, the amount thereof or payable
thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Article XIV.

     SECTION 14.05. Trustee to Effectuate Subordination.

     Each Holder by such Holder's acceptance thereof authorizes and directs the
Trustee on such Holder's behalf to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article XIV and
appoints the Trustee such Holder's attorney-in-fact for any and all such
purposes.

     SECTION 14.06. Notice by the Company.

     The Company shall give prompt written notice to a Responsible Officer of
the Trustee of any fact known to the Company that would prohibit the making of
any payment of monies to or by the Trustee in respect of the Securities pursuant
to the provisions of this Article XIV. Notwithstanding the provisions of this
Article XIV or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts that would prohibit the
making of any payment of monies to or by the Trustee in respect of the
Securities pursuant to the provisions of this Article XIV, unless and until a
Responsible Officer of the Trustee shall have received written notice thereof
from the Company or a holder or holders of Senior Debt or from any trustee
therefor; and before the receipt of any such written notice, the Trustee,
subject to the provisions of Article VI of this Indenture, shall be entitled in
all respects to assume that no such facts exist; provided, however, that if the
Trustee shall not have received the


                                       82
<PAGE>
 
notice provided for in this Section 14.06 at least two Business Days prior to
the date upon which by the terms hereof any money may become payable for any
purpose (including, without limitation, the payment of the principal of (or
premium, if any) or interest on any Security), then, anything herein contained
to the contrary notwithstanding, the Trustee shall have full power and authority
to receive such money and to apply the same to the purposes for which they were
received, and shall not be affected by any notice to the contrary that may be
received by it within two Business Days prior to such date.

     The Trustee, subject to the provisions of Article VI of this Indenture,
shall be entitled to conclusively rely on the delivery to it of a written notice
by a Person representing himself to be a holder of Senior Debt of the Company,
as the case may be (or a trustee on behalf of such holder), to establish that
such notice has been given by a holder of such Senior Debt or a trustee on
behalf of any such holder or holders. In the event that the Trustee determines
in good faith that further evidence is required with respect to the right of any
Person as a holder of such Senior Debt to participate in any payment or
distribution pursuant to this Article XIV, the Trustee may request such Person
to furnish evidence to the reasonable satisfaction of the Trustee as to the
amount of such Senior Debt held by such Person, the extent to which such Person
is entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article XIV, and, if such
evidence is not furnished, the Trustee may defer any payment to such Person
pending judicial determination as to the right of such Person to receive such
payment.

     Upon any payment or distribution of assets of the Company referred to in
this Article XIV, the Trustee and the Holders shall be entitled to rely upon any
order or decree entered by any court of competent jurisdiction in which such
insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution,
winding up or similar case or proceeding is pending, or a certificate of the
trustee in bankruptcy, liquidating trustee, custodian, receiver, assignee for
the benefit of creditors, agent or other Person making such payment or
distribution, delivered to the Trustee or to the Holders, for the purpose of
ascertaining the Persons entitled to participate in such payment or
distribution, the holders of Senior Debt and other indebtedness of the Company,
the amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article XIV.

     SECTION 14.07. Rights of the Trustee; Holders of Senior Debt.

     The Trustee in its individual capacity shall be entitled to all the rights
set forth in this Article XIV in respect of any Senior Debt at any time held by
it, to the same extent as any other holder of Senior Debt, and nothing in this
Indenture shall deprive the Trustee of any of its rights as such holder.

     With respect to the holders of Senior Debt of the Company, the Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article XIV, and no implied covenants or
obligations with respect to the holders of such Senior Debt shall be read into
this Indenture against the Trustee. The Trustee shall not be deemed to owe any
fiduciary duty to the holders of


                                       83
<PAGE>
 
such Senior Debt and, subject to the provisions of Article VI of this Indenture,
the Trustee shall not be liable to any holder of such Senior Debt if it shall
pay over or deliver to Holders, the Company or any other Person money or assets
to which any holder of such Senior Debt shall be entitled by virtue of this
Article XIV or otherwise.

     Nothing in this Article XIV shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 6.06.

     SECTION 14.08. Subordination May Not Be Impaired.

     No right of any present or future holder of any Senior Debt of the Company
to enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or by any act or failure to act, in good faith, by any such holder, or by any
noncompliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof that any such holder may have or
otherwise be charged with.

     Without in any way limiting the generality of the foregoing paragraph, the
holders of Senior Debt of the Company may, at any time and from time to time,
without the consent of or notice to the Trustee or the Holders, without
incurring responsibility to the Holders and without impairing or releasing the
subordination provided in this Article XIV or the obligations hereunder of the
Holders of the Securities to the holders of such Senior Debt, do any one or more
of the following: (i) change the manner, place or terms of payment or extend the
time of payment of, or renew or alter, such Senior Debt, or otherwise amend or
supplement in any manner such Senior Debt or any instrument evidencing the same
or any agreement under which such Senior Debt is outstanding; (ii) sell,
exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing such Senior Debt; (iii) release any Person liable in any
manner for the collection of such Senior Debt; and (iv) exercise or refrain from
exercising any rights against the Company and any other Person.


                                   ARTICLE XV

                             GUARANTEE OF SECURITIES


     SECTION 15.01. Applicability of Article; Unconditional Guarantee.

     If, pursuant to Section 2.05, provision is made for the Guarantee of the
Securities of any series by the Guarantor, then the provisions of this Article
XV, with such modifications thereto as may be specified pursuant to Section 2.05
with respect to any Securities, shall apply to such Securities. The Guarantor
hereby fully and unconditionally guarantees to each Holder of a Security of each
series authenticated and delivered by the Trustee the due and punctual payment
of the principal of (including any amount due in respect of original issue
discount), premium, if any, and interest in respect of such Security (and any
Additional Amounts payable in respect thereof) (subject to any extension of an
interest payment period pursuant to Section 2.05), and the due and punctual
payment of any sinking fund payments provided for pursuant to terms of such
Security, when and as the same shall become due and payable, whether at the
Stated Maturity, by declaration of acceleration, call for redemption or
otherwise, in accordance with the terms of such 


                                       84
<PAGE>
 
Security and of this Indenture, regardless of any defense, right of set-off or
counterclaim that the Guarantor may have or assert, except the defense of
payment. The Guarantor's obligation to make a payment under this Article XV may
be satisfied by direct payment of the required amounts by the Guarantor to the
Holders or by causing the Company to pay such amounts to the Holders.

     To the extent permitted under applicable law, if any Holder or the Trustee
is required by a final non-appealable judgment of any court or otherwise to
return to either the Company or the Guarantor, or any custodian, trustee,
liquidator or other similar official acting in relation to the Company or the
Guarantor, any amount paid by either the Company or the Guarantor to such Holder
or the Trustee, any Guarantee, to the extent theretofore discharged, shall be
reinstated in full force and effect. To the extent permitted under applicable
law, the Guarantor further agrees that, as between the Guarantor, on the one
hand, and the Holders and the Trustee, on the other hand, (x) the maturity of
the obligations guaranteed hereby may be accelerated as provided in Article V
for the purpose of any Guarantee, notwithstanding any stay, injunction or other
prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (y) in the event of any acceleration of such obligations
as provided in Article V, such obligations (whether or not due and payable)
shall forthwith become due and payable by the Guarantor for the purpose of any
Guarantee.

     No past, present or future stockholder, officer, director, employee or
incorporator of the Guarantor shall have any personal liability under the
Guarantee set forth in this Section 15.01 by reason of his or its status as such
stockholder, officer, director, employee or incorporator.

     The Guarantee set forth in this Section 15.01 shall not be valid or become
obligatory for any purpose with respect to a Security until the certificate of
authentication on such Security shall have been authenticated by or on behalf of
the Trustee by manual signature.

     SECTION 15.02. Waiver of Notice and Demand.

     The Guarantor hereby waives notice of acceptance of this guarantee and of
any liability to which it applies or may apply, presentment, demand for payment,
filing of claims with a court in the event of insolvency or bankruptcy of the
Company, any right to require a proceeding first against the Company, the
Trustee or any other Person before proceeding against the Guarantor, protest,
notice of nonpayment, notice of dishonor, notice of redemption and all other
notices and demands.

     SECTION 15.03. Guarantor Obligations Not Affected.

     The obligations, covenants, agreements and duties of the Guarantor under
this Article XV shall in no way be affected or impaired by reason of the
happening from time to time of any of the following:



                                       85
<PAGE>
 
     (a) the release or waiver, by operation of law or otherwise, of the
performance or observance by the Company of any express or implied agreement,
covenant, term or condition relating to the Securities to be performed or
observed by the Company;

     (b) the extension of time for the payment by the Company of all or any
portion of the interest on the Securities, the Redemption Price of any other
sums payable under the terms of the Securities or the extension of time for the
performance of any other obligation under, arising out of, or in connection
with, the Securities;

     (c) any failure, omission, delay or lack of diligence on the part of the
Holders to enforce, assert or exercise any right, privilege, power or remedy
conferred on the Holders pursuant to the terms of the Securities, or any action
on the part of the Company granting indulgence or extension of any kind;

     (d) the voluntary or involuntary liquidation, dissolution, receivership,
insolvency, bankruptcy, assignment for the benefit of creditors, reorganization,
arrangement, composition or readjustment of debt of, or other similar
proceedings affecting, the Company or any of the assets of the Company;

     (e) any invalidity of, or defect or deficiency in, the Securities;

     (f) the settlement or compromise of any obligation guaranteed hereby or
hereby incurred; or

     (g) any other circumstance whatsoever that might otherwise constitute a
legal or equitable discharge or defense of a guarantor (other than payment of
the underlying obligation), it being the intent of this Article XV that the
obligations of the Guarantor hereunder shall be absolute and unconditional under
any and all circumstances.

     There shall be no obligation of the Holders to give notice to, or obtain
the consent of, the Guarantor with respect to the happening of any of the
foregoing.

     SECTION 15.04. Execution of Guarantee.

     To evidence its guarantee to the Holders specified in Section 15.01, the
Guarantor hereby agrees to execute the notation of the Guarantee in
substantially the form set forth in Section 2.04 to be endorsed on each Security
authenticated and delivered by the Trustee. The Guarantor hereby agrees that its
Guarantee set forth in Section 15.01 shall remain in full force and effect
notwithstanding any failure to endorse on each Security a notation of such
Guarantee. Each such notation of the Guarantee shall be signed on behalf of the
Guarantor, by a director or officer, prior to the authentication of the Security
on which it is endorsed, and the delivery of such Security by the Trustee, after
the due authentication thereof by the Trustee hereunder, shall constitute due
delivery of the Guarantee on behalf of the Guarantor. Such signature upon the
notation of the Guarantee may be a manual or facsimile signature of any present,
past or future such director or officer and may be imprinted or otherwise
reproduced below the notation of the Guarantee, and in case any such director or
officer who shall have signed the notation 


                                       86
<PAGE>
 
of the Guarantee shall cease to be such director or officer before the Security
on which such notation is endorsed shall have been authenticated and delivered
by the Trustee or disposed of by the Company, such Security nevertheless may be
authenticated and delivered or disposed of as though the person who signed the
notation of the Guarantee had not ceased to be such director or officer of the
Guarantor.

     SECTION 15.05. Subrogation.

     The Guarantor shall be subrogated to all rights (if any) of the Holders
against the Company in respect of any amounts paid to the Holders by the
Guarantor under this Article XV with respect to any series of Securities;
provided, however, that the Guarantor shall not (except to the extent required
by mandatory provisions of law) be entitled to enforce or exercise any rights
which it may acquire by way of subrogation or any indemnity, reimbursement or
other agreement, in all cases as a result of payment under this Article XV with
respect to a series of Securities if, at any time of such payment, any amounts
are due and unpaid under such series of Securities. If any amount shall be paid
to the Guarantor in violation of the preceding sentence, the Guarantor agrees to
hold such amount in trust for the Holders and to pay over such amount to the
Holders.

     SECTION 15.06. Independent Obligations.

     The Guarantor acknowledges that its obligations hereunder are independent
of the obligations of the Company with respect to the Securities and that the
Guarantor shall be liable as principal and as debtor hereunder to make payments
pursuant to the terms of the Securities notwithstanding the occurrence of any
event referred to in subsections (a) through (g), inclusive, of Section 15.03
hereof.


                                   ARTICLE XVI

                                  SINKING FUNDS


     SECTION 16.01. Applicability of Article.

     The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of a series except as otherwise specified as
contemplated by Section 2.05 for Securities of such series.

     The minimum amount of any sinking fund payment provided for by the terms of
Securities of any series is herein referred to as a "mandatory sinking fund
payment", and any payment in excess of such minimum amount provided for by the
terms of Securities of any series is herein referred to as an "optional sinking
fund payment". If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to reduction as provided
in Section 16.02. Each sinking fund payment shall be applied to the redemption
of Securities of any series as provided for by the terms of Securities of such
series.

                                       87
<PAGE>
 
     SECTION 16.02. Satisfaction of Sinking Fund Payments with Securities.

     In lieu of making all or any part of any mandatory sinking fund payment
with respect to any series of Securities in cash, the Company may at its option
(a) deliver to the Trustee Securities of such series theretofore purchased or
otherwise acquired (except upon redemption pursuant to the mandatory sinking
fund) by the Company or receive credit for Securities of such series (not
previously so credited) theretofore purchased or otherwise acquired (except as
aforesaid) by the Company and delivered to the Trustee for cancellation pursuant
to Section 3.10, (b) receive credit for optional sinking fund payments (not
previously so credited) made pursuant to this Section 16.02, or (c) receive
credit for Securities of such series (not previously so credited) redeemed by
the Company through any optional redemption provision contained in the terms of
such series. Securities so delivered or credited shall be received or credited
by the Trustee at the sinking fund Redemption Price specified in such
Securities.

     SECTION 16.03. Redemption of Securities for Sinking Fund.

     Not less than 30 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying (a) the amount of the next ensuing sinking fund payment
for that series pursuant to the terms of that series, (b) whether or not the
Company intends to exercise its right, if any, to make an optional sinking fund
payment with respect to such series on the next ensuing sinking fund payment
date and, if so, the amount of such optional sinking fund payment, and (c) the
portion thereof, if any, which is to be satisfied by payment of cash and the
portion thereof, if any, which is to be satisfied by delivering and crediting
Securities of that series pursuant to Section 16.02, and will also deliver to
the Trustee any Securities to be so delivered. Such written statement shall be
irrevocable and upon its receipt by the Trustee the Company shall become
unconditionally obligated to make all the cash payments or payments therein
referred to, if any, on or before the next succeeding sinking fund payment date.
Failure of the Company, on or before any such 30th day, to deliver such written
statement and Securities specified in this paragraph, if any, shall not
constitute a default but shall constitute, on and as of such date, the
irrevocable election of the Company (i) that the mandatory sinking fund payment
for such series due on the next succeeding sinking fund payment date shall be
paid entirely in cash without the option to deliver or credit Securities of such
series in respect therefor and (ii) that the Company will make no optional
sinking fund payment with respect to such series as provided in this Section
16.03.

     Not less than 30 days before each such sinking fund payment date the
Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 13.03 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company
in the manner provided in Section 13.04. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 13.05, 13.06 and 13.07.

                                       88
<PAGE>
 
     The Trustee shall not redeem or cause to be redeemed any Security of a
series with sinking fund moneys or mail any notice of redemption of Securities
of such series by operation of the sinking fund during the continuance of a
default in payment of interest with respect to Securities of that series or an
Event of Default with respect to the Securities of that series except that,
where the mailing of notice of redemption of any Securities shall theretofore
have been made, the Trustee shall redeem or cause to be redeemed such
Securities, provided that it shall have received from the Company a sum
sufficient for such redemption. Except as aforesaid, any moneys in the sinking
fund for such series at the time when any such default or Event of Default,
shall occur, and any moneys thereafter paid into the sinking fund, shall, during
the continuance of such default or Event of Default, be deemed to have been
collected under Article Five and held for the payment of all such Securities. In
case such Event of Default shall have been waived as provided in Section 5.06 or
the default or Event of Default cured on or before the 30th day preceding the
sinking fund payment date, such moneys shall thereafter be applied on the next
succeeding sinking fund payment date in accordance with this Section 16.03 to
the redemption of such Securities.


                                  ARTICLE XVII

                            MISCELLANEOUS PROVISIONS


     SECTION 17.01. Consent to Jurisdiction; Appointment of Agent to Accept
Service of Process

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

     (b) Each of the Company and the Guarantor has irrevocably designated,
appointed, and empowered CT Corporation System, acting through its office at
1633 Broadway, New York, New York 10019, as its designee, appointee and agent to
receive, accept and acknowledge for and on its behalf, and its properties,
assets and revenues, service of any and all legal process, summons, notices and
documents which may be served in any legal action, suit or proceeding brought
against the Company or the Guarantor in any United States or state court. If for
any reason such designee, appointee and agent hereunder shall cease to be
available to act as such, each of the Company and the Guarantor agrees to
designate a new designee, appointee and agent in the Borough of Manhattan, The
City of New York on the terms and for the purposes of this Section 17.01

                                       89
<PAGE>
 
satisfactory to the Trustee. Each of the Company and the Guarantor further
hereby irrevocably consents and agrees to the service of any and all legal
process, summons, notices and documents in any legal action, suit or proceeding
against the Company or the Guarantor by serving a copy thereof upon the relevant
agent for service of process referred to in this Section 17.01 (whether or not
the appointment of such agent shall for any reason prove to be ineffective or
such agent shall accept or acknowledge such service) or by mailing copies
thereof by registered or certified air mail, postage prepaid, to each of the
Company or the Guarantor at its address specified in or designated pursuant to
this Indenture. Each of the Company and the Guarantor agrees that the failure of
any such designee, appointee and agent to give any notice of such service to it
shall not impair or affect in any way the validity of such service or any
judgment rendered in any action or proceeding based thereon. Nothing herein
shall in any way be deemed to limit the ability of the holders of the Securities
and the Trustee, to serve any such legal process, summons, notices and documents
in any other manner permitted by applicable law or to obtain jurisdiction over
the Company or the Guarantor or bring legal actions, suits or proceedings
against the Company or the Guarantor in such other jurisdictions, and in such
manner, as may be permitted by applicable law. Each of the Company and the
Guarantor irrevocably and unconditionally waives, to the fullest extent
permitted by law, any objection which it may now or hereafter have to the laying
of venue of any of the aforesaid actions, suits or proceedings arising out of or
in connection with this Indenture brought in the Supreme Court of New York, New
York County or the United States District Court for the Southern District of New
York and any appellate court from either thereof and hereby further irrevocably
and unconditionally waives and agrees not to plead or claim in any such court
that any such action, suit or proceeding brought in any such court has been
brought in an inconvenient forum.

     (c) To the extent that the Company or the Guarantor may in any jurisdiction
claim for itself or its assets immunity (to the extent such immunity may now or
hereafter exist, whether on the grounds of sovereign immunity or otherwise) from
suit, execution, attachment (whether in aid of execution, before judgment or
otherwise) or other legal process (whether through service or notice or
otherwise), and to the extent that in any such jurisdiction there may be
attributed to itself or its assets such immunity (whether or not claimed), the
Company and the Guarantor irrevocably agrees with respect to any matter arising
under the Indenture for the benefit of the Holders from time to time of the
Securities, not to claim, and irrevocably waives, such immunity to the full
extent permitted by the laws of such jurisdiction.

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

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

     SECTION 17.02. Successors.

     All the covenants, stipulations, promises and agreements in this Indenture
contained by the Company and the Guarantor shall bind their successors and
assigns whether so expressed or not.

     SECTION 17.03. Official Acts by Successor Corporation.

     Any act or proceeding by any provision of this Indenture authorized or
required to be done or performed by any board, committee or officer of the
Company shall and may be done and performed with like force and effect by the
like board, committee or officer of any corporation that shall at the time be
the lawful sole successor of the Company.

     SECTION 17.04. Execution in Counterparts.

     This Indenture may be executed in any number of counterparts, each of which
shall be an original, but such counterparts shall together constitute but one
and the same instrument.

     YORKSHIRE POWER FINANCE LIMITED, a limited liability company incorporated
under the laws of the Cayman Islands (herein called the "Company", which term
includes any successor corporation under the Indenture hereinafter referred to),
for value received, hereby promises to pay to the bearer upon surrender hereof,
the principal sum of __________ Dollars on ________________, and to pay interest
thereon from _____________, or from the most recent Interest Payment Date to
which interest has been paid or duly provided for, quarterly on ____________,
____________, ____________ and ____________ in each year, commencing
________________, 199__, at the rate per annum provided in the title hereof,
until the principal hereto is paid or made available for payment. The interest
so payable, and punctually paid or duly provided for, on any Interest Payment
Date will, as provided in such Indenture, be paid to the bearer on such Interest
Payment Date. So long as an Extension Period is not


                                      A-1
<PAGE>
 
occurring, any such interest not so punctually paid or duly provided for will
forthwith cease to be payable to the bearer on such Interest Payment Date and
may be paid to the bearer hereof at the time of payment of such Defaulted
Interest or be paid at any time in any other lawful manner not inconsistent with
the requirements of any securities exchange on which the Securities of this
series may be listed, and upon such notice as may be required by such exchange,
all as more fully provided in said Indenture.

     All payments in respect of this Security and all payments made pursuant to
the Guarantee of this Security shall be made in immediately available funds at
or through the office or agency of the Company maintained for that purpose in
the Borough of Manhattan, The City of New York, and, for so long as this
Security shall be listed on the Luxembourg Stock Exchange, in Luxembourg, in
such coin or currency of the United States of America as at the time of payment
is legal tender for the payment of public and private debt.

     So long as no Event of Default has occurred and is continuing, the Company
shall have the right at any time and from time to time during the term of this
Security to extend the interest payment period of such Security for up to 20
consecutive quarters but not beyond the Stated Maturity of this Security (each,
an "Extension Period"), during which periods unpaid interest (together with
interest thereon) will compound quarterly at the interest rate on this Security
("Deferred Interest"). Upon the termination of each Extension Period, which
shall be an Interest Payment Date, the Company shall pay all Deferred Interest
on the next succeeding Interest Payment Date to the bearer thereof, as provided
in the Indenture, provided that any Deferred Interest payable at Stated Maturity
or on any Redemption Date will be paid to the Person to whom principal is
payable. Prior to the termination of any such Extension Period, the Company may
extend the interest payment period, provided that such Extension Period together
with all such previous and further extensions thereof shall not exceed 20
consecutive quarters. Upon the termination of any such Extension Period, and the
payment of all accrued and unpaid interest and any Additional Interest then due,
the Company may select a new Extension Period, subject to the above
requirements. If the Company shall have given notice of its election to select
any Extension Period, neither the Company nor the Guarantor referred to herein
shall, 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 (which includes common and preferred
stock) or (ii) make any payment of principal of, or interest or premium, if any,
on or repay or repurchase or redeem any of its debt securities (including any
other Securities) that rank pari passu with or junior in interest to the
Securities or the Guarantee, respectively, or (iii) make any payments with
respect to any guarantee that ranks pari passu with or junior in interest to the
Securities or the Guarantee, respectively, or (iv) make any payment of principal
or premium, if any, or interest 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 the Company or the
Guarantor and exchanges or conversions of common stock of one class for common
stock of another class; (b) payments by the Guarantor under the Trust Securities
Guarantee (or any other



                                      A-2
<PAGE>
 
guarantee by the Guarantor 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 Securities; (c) payments by the Guarantor
under the Guarantee; (d) any dividend or payment by the Guarantor which is
applied, directly or indirectly, to the payment of any Tax Payments (e) payments
by the Guarantor, directly or indirectly, on the Intercompany Notes or any other
promissory notes held by the Company (or any other direct or indirect
wholly-owned subsidiary of the Guarantor) evidencing loans made with the
proceeds from the issuance by the Company) (or any other direct or indirect
wholly-owned subsidiary of the Guarantors) of securities guaranteed by the
Guarantor or (f) the reinvestment of any proceeds received under clause (e)
above by the Company (or any other direct or indirect wholly-owned subsidiary of
the Guarantor) in additional debt securities of the Guarantor or any of its
other direct or indirect wholly-owned subsidiaries. The Company shall give the
Holder of this Security and the Trustee notice of its selection or extension of
an Extension Period at least one Business Day prior to the earlier of (i) the
next succeeding Interest Payment Date or (ii) the date the Company is required
to give notice to the New York Stock Exchange or other applicable
self-regulatory organization or to the Holders of this Security of the record
date or Interest Payment Date, but, in any event, not less than one Business Day
prior to such record date.

     The indebtedness evidenced by this Security is, to the extent provided in
the Indenture, subordinate and subject in right of payment to the prior payment
in full of all Senior Debt (as defined in the Indenture) of the Company, and
this security is issued subject to the provisions of the Indenture with respect
thereto. Each Holder of this security, by accepting the same, (a) agrees to and
shall be bound by such provisions, (b) authorizes and directs the Trustee on his
behalf to take such action as may be necessary or appropriate to effectuate the
subordination so provided, and (c) appoints the Trustee his attorney-in-fact for
any and all such purposes. Each Holder hereof, by his acceptance thereof, waives
all notice of the acceptance of the subordination provisions contained herein
and in the Indenture by each holder of Senior Debt of the Company, whether now
outstanding or hereafter incurred, and waives reliance by each such holder upon
said provisions.

     All payments of principal of, and premium, if any, and interest in respect
of this Security and all payments made pursuant to the Guarantee of this
Security 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, the Company or the Guarantor, as
the case may be, shall pay to the Holder such additional amounts that would
otherwise have been due to such Holder in the absence of such withholding or
deduction ("Additional Amounts") except that no such Additional Amounts shall be
payable:

          (a) to, or to a Person on behalf of, a Holder who is liable for such
     Gross-Up Taxes in respect of this Security or the Guarantee of this
     Security by reason of such Holder or beneficial owner having some
     connection with the relevant Taxing



                                      A-3
<PAGE>
 
     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 this Security or the receipt of principal of, and premium, if
     any and interest in respect thereof or in respect of the Guarantee of this
     Security;

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

          (c) to, or to a Person on behalf of, a Holder who presents this
     Security (where presentation is required) in the United Kingdom 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
     nonresidence or similar claim for exemption to the relevant tax authority;
     or

          (e) to, or to a Person on behalf of, a Holder of a Registered Security
     that is not a Global Security issued pursuant to the request of owners of
     interests representing a majority in Outstanding principal amount of such
     Securities following and during the continuance of an Event of Default if
     such Holder (or any predecessor Holder) was one of such owners requesting
     that such Registered Securities be so issued.

     Such Additional Amounts will also not be payable where, had the beneficial
owner of the Security (or any interest therein) been the Holder of the Security,
he would not have been entitled to payment of Additional Amounts by reason of
any one or more of clauses (a) through (e) above. If the Company or the
Guarantor, as applicable, shall determine that Additional Amounts will not be
payable because of the immediately preceding sentence, the Company or the
Guarantor, 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 of the Trustee on
or prior to such due date, the date on which, the full amount having been so
received, notice to that effect shall have been given to the bearer hereof in
accordance with the Indenture.

     References to principal of, and premium or interest in respect of, this
Security or any payments pursuant to the Guarantee of this Security shall be
deemed to include any Additional Amounts which may be payable as set forth in
the Indenture or in this Security.

     The Company shall furnish to the Trustee the official receipts (or a
certified copy of the official receipts) evidencing payment of the Gross-Up
Taxes.



                                      A-4
<PAGE>
 
Copies of such receipts shall be made available to the Holder of this Security
upon request.

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

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

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

                         YORKSHIRE POWER FINANCE LIMITED
        ___% Junior Subordinated Deferrable Interest Debenture, Series A
                             due ____________, 2038

     This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or more
series under an Indenture, dated as of May 1, 1998 (herein called the "Original
Indenture"), among the Company, Yorkshire Power Group Limited, as guarantor (the
"Guarantor"), The Bank of New York, as trustee, principal paying agent,
registrar and transfer agent (herein called the "Trustee", which term includes
any successor trustee under the Indenture), and Banque Generale du Luxembourg
S.A., as paying and transfer agent (the "Paying and Transfer Agent"), as
supplemented by the First Supplemental Indenture, dated as of May __, 1998
(together with the Original Indenture and any other supplements thereto, the
"Indenture"), among the Company, the Guarantor, the Trustee and the Paying and
Transfer Agent to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities thereunder of the Company, the Guarantor, the
Trustee, the Paying and Transfer Agent and the Holders of the Securities and of
the terms upon which the Securities are, and are to be, authenticated and
delivered. This Security is one of the series designated on the face hereof,
limited in aggregate principal amount to $275,000,000.

     The Company shall have the right, subject to the terms and conditions of
the Indenture, to redeem this Security at any time on or after ___________,
2003, at the option of the Company, without premium or penalty, in whole or in
part, at a Redemption Price equal to 100% of the principal amount to be redeemed
plus any accrued and unpaid interest, including Additional Interest, if any, to
the Redemption Date. Upon the occurrence of a Special Event (as defined below)
at any time, the Company may, within 90 days following the occurrence thereof
and subject to the terms and conditions of the Indenture, redeem this Security
without premium or penalty, in whole, at a Redemption Price equal to 100% of the
principal amount thereof plus any accrued and unpaid interest, including
Additional Interest, if any, to the Redemption Date. A Special Event may be a
Tax Event or an Investment Company Act Event.

"Tax Event" means the receipt by the Guarantor or the Company of an opinion of
independent counsel (which may be counsel to the Guarantor 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 supra national federation to which the United
Kingdom belongs or the jurisdiction (or any political subdivision or taxing
authority thereof or therein) in which the Company or the Guarantor is
incorporated or created, as applicable, or in which the Company or the Guarantor
is managed 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 threatened challenge
asserted by a government or taxing authority with respect to the Guarantor or
any of its



                                      A-7
<PAGE>
 
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 Securities or the
Trust Securities, which amendment or change is effective or which pronouncement
clarification, challenge or decision is announced on or after May __, 1998, and
that results in their being more than an insubstantial risk that (i) the Company
is, or will be within 90 days of the date thereof , subject to income tax within
a Taxing Jurisdiction (other than the United Kingdom corporation income tax)
with respect to interest received or accrued on the Intercompany Notes, (ii) the
Company 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 payable by the Company on the Securities is not, or within 90 days of
the date thereof will not be, deductible, in whole or in part for United States
Federal income tax or United Kingdom corporation income tax purposes, as they
accrue by the Company or by a member of any tax group to which the Guarantor
belongs or (iv) interest payable with respect to the Intercompany Notes by the
Guarantor 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) United States
Federal or United Kingdom corporation income tax purposes, by one of (as
appropriate) the Guarantor, its shareholders or a member of any tax group to
which the Guarantor belongs. "Investment Company Act Event" shall mean that the
Guarantor or the Company shall have received an opinion of independent counsel
(which may be counsel to the Guarantor 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
the Guarantor or the Company is or will be considered an "investment company"
that is required to be registered under the Investment Company Act of 1940, as
amended, which Investment Company Act Change becomes effective on or after May
__, 1998.

     Notice of redemption shall be given as provided in the Indenture not less
than 30 days nor more than 60 days prior to the date fixed for redemption.

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

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

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



                                      A-8
<PAGE>
 
     If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture. At any time after such declaration of acceleration with respect to
Securities of any series has been made, but before a judgment or decree for
payment of money has been obtained by the Trustee as provided in the Indenture,
if all Events of Default with respect to Securities of this series have been
cured or waived (other than the non-payment of principal of the Securities which
has become due solely by reason of such declaration of acceleration) then such
declaration of acceleration and its consequences shall be automatically annulled
and rescinded.

     The Securities of this Series are subject to redemption in whole but not in
part upon not less than 30 nor more than 60 days' notice given as provided in
the Indenture, at a price equal to the outstanding principal amount thereof,
together with Additional Amounts, if any, and accrued and unpaid interest, if
any, to the Redemption Date if, (a) the Company or the Guarantor satisfies the
Trustee prior to the giving of such notice that it has or will become obligated
to pay Additional Amounts with respect to the Securities or the Guarantee as a
result of either (i) 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 May __, 1998 or (ii) the issuance of
Definitive Registered Series A Debentures Securities pursuant to any of clauses
(a), (b) or (d) of the third following paragraph and (b) such obligation cannot
be avoided by the Company or the Guarantor taking reasonable measures available
to it, subject, as provided in the Indenture, to the delivery by the Company or
the Guarantor of an Officers' Certificate stating that such obligation to pay
Additional Amounts cannot be avoided by the Company or the Guarantor taking
reasonable measures available to it.

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

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



                                      A-9
<PAGE>
 
and unconditional, to pay the principal of, and premium, if any and interest, if
any, on this Security and all payments made pursuant to the Guarantee of this
Security at the times, place and rate, and in the coin or currency, herein
prescribed.

     This Security shall be exchangeable, in whole or, in the case of clause (d)
below, in part as provided in the Indenture, for Definitive Registered Series A
Debentures registered in the names of Persons other than the Book-Entry
Depositary with respect to such series or its nominee only as provided in this
paragraph. This Security shall be so exchangeable if (a) DTC notifies the
Company and the Book-Entry Depositary that it is unwilling or unable to continue
to hold the Book-Entry Interests or 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 the Company within 120 days, (b) the Book-Entry Depositary for
the Securities of this series notifies the Company that it is unwilling or
unable to continue as Book-Entry Depositary with respect to this Security and no
successor is appointed within 120 days, (c) the Company executes and delivers to
the Trustee an Officers' Certificate providing that this Security shall be so
exchangeable, or (d) there shall have occurred and be continuing an Event of
Default with respect to the Securities of this series and the Holder, in such
circumstance, shall have requested in writing that this Security be exchanged
for one or more Definitive Registered Series A Debentures. Securities so issued
in exchange for this Security shall be of the same series, having the same
interest rate, if any, and maturity and having the same terms as this Security,
in authorized denominations and in the aggregate having the same principal
amount as this security and registered in such names as the Book-Entry
Depositary for this Security shall direct.

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

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

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

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

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



                                      A-10
<PAGE>
 
releases all such liability. The waiver and release are part of the
consideration for the issuance of the Securities of this series.

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

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

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

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

                                    GUARANTEE

     FOR VALUE RECEIVED, YORKSHIRE POWER GROUP LIMITED, a private limited
company duly incorporated and existing under the laws of England and Wales (the
"Guarantor", which term includes any successor Person under the Indenture
referred to in the Security on which this notation is endorsed), hereby fully
and unconditionally guarantees to the Holder of the accompanying Security issued
by Yorkshire Power Finance Limited (the "Company"), pursuant to the terms of the
Guarantee contained in Article XV of the Indenture, the due and punctual payment
of the principal of, and premium, if any, and interest in respect of this
Security (and any Additional Amounts payable in respect thereof), when and as
the same shall become due and payable, whether at Stated Maturity, by
declaration of acceleration, call for redemption or otherwise, in accordance
with the terms of this Security and the Indenture. In case of the failure of the
Company punctually to pay any such principal, premium, if any, or interest, the
Guarantor hereby agrees to cause any such payment to be made punctually when and
as the same shall become due and payable as if such payment were made by the
Company.

     The obligations of the Guarantor to the Holders of the Securities and to
the Trustee pursuant to the Guarantee and the Indenture are expressly set forth
in Article XV of the Indenture, and reference is hereby made to such Article and
Indenture for the precise terms of the Guarantee.

     THIS GUARANTEE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF NEW YORK.

     YORKSHIRE POWER FINANCE LIMITED, a limited liability company incorporated
under the laws of the Cayman Islands (herein called the "Company", which term
includes any successor corporation under the Indenture hereinafter referred to),
for value received, hereby promises to pay to [name of registered owner], or its
registered assigns, the principal sum of _______________ Dollars on
_______________________, and to pay interest thereon from ____________________,
or from the most recent Interest Payment Date to which interest has been paid or
duly provided for, quarterly on __________, __________, __________ and
_____________ in each year, commencing _______________, 199_, at the rate per
annum provided in the title hereof, until the principal hereof is paid or made
available for payment. The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in such Indenture,
be paid to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest, which shall be the fifteenth day (whether or not a Business
Day) immediately preceding such Interest Payment Date. So long as an Extension
Period is not occurring, any such interest not so punctually paid or duly
provided for will forthwith cease to be payable to the Person in whose name this
Security (or one or more Predecessor Securities) is registered on such Regular
Record Date and may be paid to the Person in whose name this Security (or one or
more Predecessor Securities) is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Holders of Securities of this series
not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Securities of this series may be listed, and
upon such notice as may be required by such exchange, all as more fully provided
in said Indenture.

     All payments in respect of this Security and all payments made pursuant to
the Guarantee of this Security shall be made in immediately available funds at
or through the office or agency of the Company maintained for that purpose in
the Borough of Manhattan, The City of New York, and for so long as this Security
shall be listed on the Luxembourg Stock Exchange, in Luxembourg, in such coin or
currency of the United

public and private debt; provided, however, that at the option of the Company,
payment of interest may be made by check mailed to the address of the Person
entitled thereto as such address shall appear in the Security Register.

     So long as no Event of Default has occurred and is continuing, the Company
shall have the right at any time and from time to time during the term of this
Security to extend the interest payment period of such Security for up to 20
consecutive quarters but not beyond the Stated Maturity of this Security (each,
an "Extension Period"), during which periods unpaid interest (together with
interest thereon) will compound quarterly at the interest rate on this Security
("Deferred Interest"). Upon the termination of each Extension Period, which
shall be an Interest Payment Date, the Company shall pay all Deferred Interest
on the next succeeding Interest Payment Date to the Person in whose name this
Security is registered at the close of business on the Regular Record Date for
such Interest Payment Date, provided that any Deferred Interest payable at
Stated Maturity or on any Redemption Date will be paid to the Person to whom
principal is payable. Prior to the termination of any such Extension Period, the
Company may extend the interest payment period, provided that such Extension
Period together with all such previous and further extensions thereof shall not
exceed 20 consecutive quarters. Upon the termination of any such Extension
Period, and the payment of all accrued and unpaid interest and any Additional
Interest then due, the Company may select a new Extension Period, subject to the
above requirements. If the Company shall have given notice of its election to
select any Extension Period, neither the Company nor the Guarantor referred to
herein shall, 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 (which includes common and preferred
stock) or (ii) make any payment of principal of, or interest or premium, if any,
on or repay or repurchase or redeem any of its debt securities (including any
other Securities) that rank pari passu with or junior in interest to the
Securities or the Guarantee, respectively, or (iii) make any payments with
respect to any guarantee that ranks pari passu with or junior in interest to the
Securities or the Guarantee, respectively, or (iv) make any payment of principal
or premium, if any, or interest 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 the Company or the
Guarantor and exchanges or conversions of common stock of one class for common
stock of another class; (b) payments by the Guarantor under the Trust Securities
Guarantee (or any other guarantee by the Guarantor 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
Securities); (c) payments by the Guarantor under the Guarantee; (d) any dividend
or payment by the Guarantor which is applied, directly or indirectly, to the
payment of any Tax Payments (e) payments by the Guarantor, directly or
indirectly, on the Intercompany Notes or any other promissory notes held by the
Company (or any other direct or indirect wholly-owned subsidiary of the
Guarantor) evidencing loans made with the proceeds from the issuance by the
Company (or any other direct or indirect wholly-owned subsidiary of the
Guarantors) of securities guaranteed by the Guarantor or



                                      B-2

(f) the reinvestment of any proceeds received under clause (e) above by the
Company (or any other direct or indirect wholly-owned subsidiary of the
Guarantor) in additional debt securities of the Guarantor or any of its other
direct or indirect wholly-owned subsidiaries. The Company shall give the Holder
of this Security and the Trustee notice of its selection or extension of an
Extension Period at least one Business Day prior to the earlier of (i) the next
succeeding Interest Payment Date or (ii) the date the Company is required to
give notice to the New York Stock Exchange or other applicable self-regulatory
organization or to the Holders of this Security of the record date or Interest
Payment Date, but, in any event, not less than one Business Day prior to such
record date.

     All payments of principal of, premium, if any, and interest in respect of
this Security and all payments made pursuant to the Guarantee of this Security
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, the Company or the Guarantor, as the case
may be, shall pay to the Holder such additional amounts that would otherwise
have been due to such Holder in the absence of such withholding or deduction
("Additional Amounts"), except that no such Additional Amounts shall be payable:

          (a) to, or to a Person on behalf of, a Holder who is liable for such
     Gross-Up Taxes in respect of this Security or the Guarantee of this
     Security by reason of such Holder having some connection with the relevant
     Taxing Jurisdiction (including 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 this Security or the receipt of principal of, premium, if any,
     and interest in respect thereof or in respect of the Guarantee of this
     Security;

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

          (c) to, or to a Person on behalf of, a Holder who presents a Security
     (where presentation is required) in the United Kingdom 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
     nonresidence or similar claim for exemption to the relevant tax authority;
     or

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



                                      B-3
<PAGE>
 
     representing a majority in outstanding principal amount in the Book-Entry
     Interest following and during the continuance of an Event of Default if
     such Holder (or any predecessor Holder) was one of such owners requesting
     that definitive Registered Securities be so issued.

     Such Additional Amounts will also not be payable where, had the beneficial
owner of the Security (or any interest therein) been the Holder of the Security,
he would not have been entitled to payment of Additional Amounts by reason of
any one or more of clauses (a) through (e) above. If the Company or the
Guarantor, as applicable, shall determine that Additional Amounts will not be
payable because of the immediately preceding sentence, the Company or the
Guarantor, 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 Trustee or the Holder on or prior to
such due date, the date on which, the full amount having been so received,
notice to that effect shall have been given to the Holder in accordance with
this Indenture.

     References to principal of, and premium or interest in respect of, this
Security or payments under the Guarantee of this Security shall be deemed to
include to any Additional Amounts which may be payable as set forth in the
Indenture or in this Security.

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

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

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

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

                          [Form of Reverse of Security]

                         YORKSHIRE POWER FINANCE LIMITED
             ___% Junior Subordinated Deferrable Interest Debenture,
                          Series A due __________, 2038

     This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or more
series under an Indenture, dated as of May 1, 1998 (herein called the "Original
Indenture"), among the Company, Yorkshire Power Group Limited, as guarantor (the
"Guarantor"), The Bank of New York, as trustee principal paying agent, register
and transfer agent (herein called the "Trustee", which term includes any
successor trustee under the Indenture), and Banque Generale du Luxembourg S.A.,
as paying and transfer agent (the "Paying and Transfer Agent"), as supplemented
by the First Supplemental Indenture, dated as of May __, 1998 (together with the
Original Indenture and any other supplements thereto, the "Indenture") among the
Company, the Guarantor, the Trustee and the Paying and Transfer Agent to which
Indenture and all indentures supplemental thereto reference is hereby made for a
statement of the respective rights, limitations of rights, duties and immunities
thereunder of the Company, the Guarantor, the Trustee, the Paying and Transfer
Agent and the Holders of the Securities and of the terms upon which the
Securities are, and are to be, authenticated and delivered. This Security is one
of the series designated on the face hereof, limited in aggregate principal
amount to $275,000,000.

     The Company shall have the right, subject to the terms and conditions of
the Indenture, to redeem this Security at any time on or after ___________,
2003, at the option of the Company, without premium or penalty, in whole or in
part, at a Redemption Price equal to 100% of the principal amount to be redeemed
plus any accrued and unpaid interest, including Additional Interest, if any, to
the Redemption Date. Upon the occurrence of a Special Event (as defined below)
at any time, the Company may, within 90 days following the occurrence thereof
and subject to the terms and conditions of the Indenture, redeem this Security
without premium or penalty, in whole, at a Redemption Price equal to 100% of the
principal amount thereof plus any accrued and unpaid interest, including
Additional Interest, if any, to the Redemption Date. A Special Event may be a
Tax Event or an Investment Company Act Event.

"Tax Event" means the receipt by the Guarantor or the Company of an opinion of
independent counsel (which may be counsel to the Guarantor 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 supra national federation to which the United
Kingdom belongs or the jurisdiction (or any political subdivision or taxing
authority thereof or therein) in which the Company or the Guarantor is
incorporated or created, as applicable, or in which the Company or the Guarantor
is managed 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 threatened challenge
asserted by a government or taxing authority with respect to the Guarantor or
any of its



                                      B-6
<PAGE>
 
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 Securities or the
Trust Securities, which amendment or change is effective or which pronouncement
clarification, challenge or decision is announced on or after May __, 1998, and
that results in their being more than an insubstantial risk that (i) the Company
is, or will be within 90 days of the date thereof , subject to income tax within
a Taxing Jurisdiction (other than the United Kingdom corporation income tax)
with respect to interest received or accrued on the Intercompany Notes, (ii) the
Company 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 payable by the Company on the Securities is not, or within 90 days of
the date thereof will not be, deductible, in whole or in part for United States
Federal income tax or United Kingdom corporation income tax purposes, as they
accrue by the Company or by a member of any tax group to which the Guarantor
belongs or (iv) interest payable with respect to the Intercompany Notes by the
Guarantor 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) United States
Federal or United Kingdom corporation income tax purposes, by one of (as
appropriate) the Guarantor, its shareholders or a member of any tax group to
which the Guarantor belongs. "Investment Company Act Event" shall mean that the
Guarantor or the Company shall have received an opinion of independent counsel
(which may be counsel to the Guarantor 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
the Guarantor or the Company is or will be considered an "investment company"
that is required to be registered under the Investment Company Act of 1940, as
amended, which Investment Company Act Change becomes effective on or after May
__, 1998.

     Notice of redemption shall be given as provided in the Indenture not less
than 30 days nor more than 60 days prior to the date fixed for redemption.

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

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

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



                                      B-7
<PAGE>
 
     If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture. At any time after such declaration of acceleration with respect to
Securities of any series has been made, but before a judgment or decree for
payment of money has been obtained by the Trustee as provided in the Indenture,
if all Events of Default with respect to Securities of this series have been
cured or waived (other than the nonpayment of principal of the Securities which
has become due solely by reason of such declaration of acceleration) then such
declaration of acceleration and its consequences shall be automatically annulled
and rescinded.

     The Securities of this series are subject to redemption upon not less than
30 nor more than 60 days' notice to the Holders of Securities by first-class
mail, at a price equal to the outstanding principal amount thereof, together
with Additional Amounts, if any, and accrued interest, if any, to the Redemption
Date if (a) the Company or the Guarantor satisfies the Trustee prior to the
giving of such notice that it has or will become obligated to pay Additional
Amounts with respect to the Securities or the Guarantee as a result of either
(i) 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 May __, 1998 or (ii) the issuance of Definitive Registered
Series A Notes as a result of: (A) DTC having notified the Company and the
Book-Entry Depositary that it was unwilling or unable to continue to hold the
Book-Entry Interests or at any time ceasing to be a "clearing agency" registered
as such under the Securities Exchange Act of 1934 and, in either case, a
successor is not being appointed by the Company within 120 days; (B) the
Book-Entry Depositary for the Securities of this series having notified the
Company that it was unwilling or unable to continue as Book-Entry Depositary
with respect to a Global security of this series and no successor Book-Entry
Depositary having been appointed by the Company within 120 days or (C) an Event
of Default with respect to the Securities of this series having occurred and
being continuing and a Holder, in such circumstance, having requested in writing
that a Global Bearer Series A Notes be exchanged for one or more Definitive
Registered Series A Notes and (b) such obligation cannot be avoided by the
Company and the Guarantor taking reasonable measures available to it, subject,
as provided in the Indenture, to the delivery by the Company or the Guarantor of
an Officers Certificate that such obligation referred to in (a) cannot be
avoided by the Company or the Guarantor taking reasonable measures available to
it.

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



                                      B-8
<PAGE>
 
Company with certain provisions of the Indenture and certain past defaults under
the Indenture and their consequences. Any such consent or waiver by the Holder
of this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the registration
of transfer hereof or in exchange herefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Security.

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

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

     The Securities of this series are issuable only in registered form without
coupons in denominations of $25 and any integral multiple thereof. As provided
in the Indenture and subject to certain limitations therein set forth,
Securities of this series are exchangeable for a like aggregate principal amount
of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.

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

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

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

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

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

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

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

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

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

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

                                 TRUST AGREEMENT

     THIS TRUST AGREEMENT is made as of February 1, 1998, by and among AEP
Resources, Inc., an Ohio corporation, as Depositor (the "Depositor"), Stephan T.
Haynes, as "Administrative Trustee", The Bank of New York, a New York banking
corporation, as "Property Trustee" and The Bank of New York (Delaware), duly
organized and existing in the State of Delaware, as "Delaware Trustee" (the
Property Trustee, the Delaware Trustee and the Administrative Trustee together,
the "Trustees"). The Depositor and the Trustees hereby agree as follows:

     1. The trust created hereby shall be known as "Yorkshire Capital Trust I",
in which name the Trustees, the Depositor or the holder of the Control
Certificate (as herein defined), to the extent provided herein, may conduct the
business of the Trust, make and execute contracts, and sue and be sued.

     2. The Depositor hereby assigns, transfers, conveys and sets over to the
Trust the sum of $10. Such amount shall constitute the initial trust estate. It
is the intention of the parties hereto that the Trust created hereby constitute
a business trust under Chapter 38 of Title 12 of the Delaware Code, 12 Del. C.
ss. 3801, et seq. (the "Business Trust Act"), and that this document constitute
the governing instrument of the Trust. The Trustees are hereby authorized and
directed to execute and file a certificate of trust with the Delaware Secretary
of State substantially in the form attached hereto or in such other form as the
Trustees may approve.

     3. The Depositor and the Trustees will enter into an amended and restated
Trust Agreement (the "Amended and Restated Trust Agreement") satisfactory to
each such party and substantially in the form included as an exhibit to the
Registration Statement (the "1933 Act Registration Statement") filed under the
Securities Act of 1933, as amended (the "1933 Act"), or in such other form as
the Depositor and the holder of the Control Certificate (as herein defined) may
approve, to provide for the contemplated operation of the Trust created hereby
and the issuance of the Preferred Securities, as referred to therein. Prior to
the execution and delivery of such Amended and Restated Trust Agreement, the
Trustees shall not have any duty or obligation hereunder or with respect to the
trust estate, except as otherwise required by applicable law or as may be
necessary to obtain prior to such execution and delivery any licenses, consents
or approvals required by applicable law or otherwise. However, notwithstanding
the foregoing, the Trustees may take all actions deemed proper as are necessary
to effect the transactions contemplated herein.

     4. The Depositor and the Trustees agree that, subsequent to the execution
of this Trust Agreement and prior to the execution of the Amended and Restated
Trust Agreement, the Depositor shall transfer an instrument (the "Control
Certificate") which will establish in the holder of such Control Certificate, in
addition to its rights, powers and duties hereunder, certain voting,
administrative and appointment powers with respect to the Trust. Such voting,
administrative and appointment powers shall be specified in the Amended and
Restated Trust Agreement.

     5. The Depositor, as the sponsor of the Trust, and the holder of the
Control Certificate, as the case may be, acting singly or jointly, is hereby
authorized, to cause the following actions to be taken (i) to file with the
Securities and Exchange Commission (the "Commission"), on behalf of
<PAGE>
 
the Trust, (a) the 1933 Act Registration Statement including pre-effective or
post-effective amendments to such Registration Statement, relating to the
registration under the 1933 Act of the Preferred Securities of the Trust, (b)
any preliminary prospectus or prospectus or supplement thereto relating to the
Preferred Securities required to be filed pursuant to Rule 424 under the 1933
Act, and (c) a Registration Statement on Form 8-A or other appropriate form (the
"1934 Act Registration Statement") (including all pre-effective and
post-effective amendments thereto) relating to the registration of the Preferred
Securities of the Trust under Section 12(b) of the Securities Exchange Act of
1934, as amended; (ii) to file with the New York Stock Exchange or any other
exchange and execute on behalf of the Trust a listing application and all other
applications, statements, certificates, agreements and other instruments as
shall be necessary or desirable to cause the Preferred Securities to be listed
on the New York Stock Exchange or any other exchange; (iii) to file and execute
on behalf of the Trust such applications, reports, surety bonds, irrevocable
consents, appointments of attorney for service of process and other papers and
documents as shall be necessary or desirable to register the Preferred
Securities under the securities or "Blue Sky" laws of such jurisdictions as the
Depositor, on behalf of the Trust, may deem necessary or desirable; and (iv) to
execute, deliver and perform on behalf of the Trust an underwriting agreement
with respect to the Preferred Securities of the Trust. The Trustees further
hereby ratify and approve all actions having previously been taken with respect
to the foregoing. In the event that any filing referred to in clauses (i)-(iii)
above is required by the rules and regulations of the Commission, the New York
Stock Exchange or any other exchange or state securities or Blue Sky laws to be
executed on behalf of the Trust by the Trustee, the Property Trustee and the
Delaware Trustee, in their capacities as trustees of the Trust, are hereby
authorized and directed to join in any such filing and to execute on behalf of
the Trust any and all of the foregoing, it being understood that the Property
Trustee and the Delaware Trustee in their capacities as trustees of the Trust
shall not be required to join in any such filing or execute on behalf of the
Trust any such document unless required by the rules and regulations of the
Commission, the New York Stock Exchange or any other exchange or state
securities or Blue Sky laws.

     6. This Trust Agreement may be executed in one or more counterparts.

     7. The number of Trustees initially shall be three (3) and thereafter the
number of Trustees shall be such number as shall be fixed from time to time by a
written instrument signed by the Depositor or the holder of the Control
Certificate which may increase or decrease the number of Trustees; provided,
however, that to the extent required by the Business Trust Act, one Trustee
shall either be a natural person who is a resident of the State of Delaware or,
if not a natural person, an entity which has its principal place of business in
the State of Delaware.

     8. From and after issuance of the Control Certificate, this Trust
Agreement may be amended, modified or restated only with the consent of the
holder of the Control Certificate.

     9. This Trust Agreement shall be construed in accordance with and governed
by the internal laws of the State of Delaware.

          (b)   The amount of Distributions payable for any full quarterly
period shall be computed on the basis of twelve 30-day months and a 360-day year
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. If the interest payment
period for the Junior Subordinated Debentures is extended pursuant to Section
_____ of the Supplemental Indenture (an "Extension Period"), then the rate per
annum at which Distributions on the Trust Securities accumulate shall be
increased by an amount such that the aggregate amount of Distributions that
accumulate on all Trust Securities during any such Extension Period is equal to
the aggregate amount of interest (including interest payable on unpaid interest
at the percentage rate per annum set forth above, compounded quarterly, to the
extent permitted by applicable law) that accrues during any such Extension
Period on the Junior Subordinated Debentures. The payment of such deferred
interest, together with interest thereon, will be distributed to the Holders of
the Trust Securities as received at the end of any Extension Period. Additional
sums received by the Trust for any period shall be distributed to the Holders of
Trust Securities in respect of such period in order that the entire amount
payable for such period under this Section 4.01 shall be distributed when
payable.

          (c)   Distributions on the Trust Securities shall be made and shall be
deemed payable on each Distribution Date only to the extent that the Trust has
sufficient funds available in the Payment Account for the payment of such
Distributions.

          (d)   Distributions, if any, on the Trust Securities on each
Distribution Date shall be payable to the Holders thereof as they appear on the
Securities Register for the Trust Securities on the relevant record date, which,
as long as the Trust Securities are represented by Book-Entry Trust Securities
Certificate, shall be one Business Day prior to the relevant Distribution Date.
In the event that any Trust Securities are not so represented, the relevant
record date for such Trust Securities shall be the close of business on the
fifteenth calendar day prior to the relevant Distribution Date.

          Each Trust Security upon registration of transfer of or in exchange
for or in lieu of any other Trust Security shall carry the rights of
Distributions accumulated and unpaid, and to accumulate, which were carried by
such other Trust Security.

          Section 4.02    Redemption.
                          ---------- 

          (a)   On each Indenture Redemption Date with respect to, and on the
stated maturity of, the Junior Subordinated Debentures, the Trust will be
required to redeem a Like Amount of Trust Securities at the Redemption Price.

          (b)   Provided that the Property Trustee has received a written
direction from the Control Party to effect such redemption at least 45 days
prior to the Redemption Date, notice of redemption shall be given by the
Property Trustee by first-class mail, postage prepaid, mailed not less than 30
nor more than 60 days' prior to the Redemption Date to each Holder of Trust
Securities to be redeemed, at such Holder's address appearing in the Securities
Register.  All notices of redemption shall state:

                                       19
<PAGE>
 
          (i)      the Redemption Date;

          (ii)     the Redemption Price;

          (iii)    the CUSIP number;

          (iv)     if less than all the Outstanding Trust Securities are to be
     redeemed, the identification the total Liquidation Amount of the particular
     Trust Securities selected by the Property Trustee to be redeemed; and

          (v)      that on the Redemption Date the Redemption Price will become
     due and payable upon each such Trust Security to be redeemed and that
     Distributions thereon will cease to accumulate on and after such date.

          (c)   The 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 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 in the Payment Account at 10:00 AM on the
Redemption Date for the payment of such Redemption Price.

          (d)   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 Section 4.02(c), the Property Trustee will, so long
as the Trust Securities are in represented by Book-Entry Trust Securities
Certificates, irrevocably deposit with the Clearing Agency funds sufficient to
pay the applicable Redemption Price and will give the Clearing Agency
irrevocable instructions and authority to pay the Redemption Price to the
Holders thereof.  If the Trust Securities are not represented by Book-Entry
Trust Securities Certificates, the Property Trustee, subject to Section 4.02(c),
will irrevocably deposit with the Paying Agent funds sufficient to pay the
applicable Redemption Price and will give the Paying Agent irrevocable
instructions and authority to pay the Redemption Price to the Holders thereof
upon surrender of their Trust Securities Certificates.  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 they appear on the Securities Register for the Trust
Securities on 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 Securityholders holding Trust
Securities so called for redemption will cease, except the right of such
Securityholders to receive the Redemption Price, but without interest, and such
Trust Securities will cease to be Outstanding.  In the event that any Redemption
Date is not a Business Day, then payment of the Redemption Price payable on such
date shall 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 

                                       20
<PAGE>
 
respect of Trust Securities is improperly withheld or refused and not paid
either by the Trust or by Yorkshire Group pursuant to the Guarantee or the
Debentures Guarantee, Distributions on such Trust Securities will continue to
accumulate at the then applicable rate from such 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.

          (e)   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, and which shall provide for the selection for redemption
of portions (equal to $25 or an integral multiple of $25 in excess thereof) of
the aggregate Liquidation Amount of Trust Securities of a denomination larger
than $25.  The Property Trustee shall promptly notify the Securities Registrar
in writing of the Trust Securities selected for redemption and, in the case of
any Trust Securities selected for partial redemption, the Liquidation Amount
thereof to be redeemed.  For all purposes of this Trust Agreement, unless the
context otherwise requires, all provisions relating to the redemption of Trust
Securities shall relate, in the case of any Trust Securities redeemed or to be
redeemed only in part, to the portion of the Liquidation Amount of Trust
Securities which has been or is to be redeemed.

          (f)   Subject to the foregoing provisions of this Section 4.02 and to
applicable law (including, without limitation, applicable United States federal
securities laws), 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.

          Section 4.03    Payment Procedures.  Payments in respect of the Trust
                          ------------------
Securities shall be made by check mailed to the address of the Person entitled
thereto as such address shall appear on the Securities Register or, if the Trust
Securities are held by a Clearing Agency in immediately available funds, such
Distributions shall be made to the Clearing Agency, which shall credit the
relevant Persons' accounts at such Clearing Agency on the applicable
Distribution Dates.

          Section 4.04    Tax Returns and Reports.  The Administrative Trustees
                          -----------------------
shall prepare (or cause to be prepared), at the expense of the US Affiliates
pursuant to the Expense Agreement, and file all United States federal, state and
local tax and information returns and reports required to be filed by or in
respect of the Trust. The Administrative Trustees shall provide or cause to be
provided on a timely basis to each Holder any Internal Revenue Service form
required to be so provided in respect of the Trust Securities. The Property
Trustee shall comply with United States federal withholding and back-up
withholding tax laws and information reporting requirements with respect to any
payments to Securityholders.

executed on behalf of the Trust by manual or facsimile signature of at least one
Administrative Trustee. Trust Securities Certificates bearing the manual or

delivered to or upon the written order of the Control Party signed by its
Chairman of the Board, its President, any Vice President, or any Director

Property Trustee by manual signature; such authentication shall constitute
conclusive evidence that such Trust Securities Certificate shall have been duly
authenticated and delivered hereunder. All Trust Securities Certificates shall
be dated the date of their authentication.

Securities Certificates.  The Securities Registrar shall keep or cause to be 
- -----------------------
kept, at the office or agency maintained pursuant to Section 5.08, a Securities
Register in which, subject to such reasonable regulations as it may prescribe,
the Securities Registrar shall provide for the registration of Trust Securities
Certificates and registration of transfers and exchanges of Trust Securities

Securities Registrar.

          Upon surrender for registration of transfer of any Trust Securities
Certificate at the office or agency maintained pursuant to Section 5.08, the
Administrative Trustees shall execute, authenticate and deliver in the name of
the designated transferee or transferees one or more new Trust Securities
Certificates in authorized denominations of a like aggregate Liquidation Amount
dated the date of authentication by the Administrative Trustee or Trustees.  The
Securities Registrar shall not be required to register the transfer of any Trust
Securities that have been called for redemption.  At the option of a Holder,
Trust Securities Certificates may be exchanged for other Trust Securities
Certificates in authorized denominations of the same class and of a like
aggregate Liquidation Amount upon surrender of the Trust Securities Certificates
to be exchanged at the office or agency maintained pursuant to Section 5.08.

          Every Trust Securities Certificate presented or surrendered for
registration of transfer or exchange shall be accompanied by a written
instrument of transfer in form satisfactory to the Administrative Trustees and
the Securities Registrar duly executed by the Holder or his attorney duly
authorized in writing.  Each Trust Securities Certificate surrendered for
registration of transfer or exchange shall be canceled and subsequently disposed
of by the Securities Registrar in accordance with its customary practice.

          No service charge shall be made for any registration of transfer or
exchange of Trust Securities Certificates, but the Securities Registrar or the
Administrative Trustees may require payment of a sum sufficient to cover any tax
or governmental charge that may be imposed in connection with any transfer or
exchange of Trust Securities Certificates.

surrendered to the Securities Registrar, or if the Securities Registrar shall
receive evidence to its satisfaction of the destruction, loss or theft of any
Trust Securities Certificate and (b) there shall be delivered to the Securities
Registrar and the Administrative Trustees such security or indemnity as may be
required by them to save each of them harmless, then in the absence of notice
that such Trust Securities Certificate shall have been acquired by a bona fide
purchaser, the Administrative Trustees or any one of them on behalf of the Trust
shall execute and authenticate and make available for delivery, in exchange for
or in lieu of any such mutilated, destroyed, lost or stolen Trust Securities
Certificate, a new Trust Securities Certificate of like class, tenor and
denomination. In connection with the issuance of any new Trust Securities
Certificate under this Section, the Administrative Trustees or the Securities
Registrar may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection therewith. Any duplicate
Trust Securities Certificate issued pursuant to this Section shall constitute
conclusive evidence of an ownership interest in the Trust, as if originally
issued, whether or not the lost, stolen or destroyed Trust Securities
Certificate shall be found at any time.

(i) the Control Party and the Property Trustee semi-annually, not later than
June 1 and December 1 in each year, and (ii) the Control Party or the Property
Trustee, as the case may be, within 30 days after receipt by any Administrative
Trustee of a request therefor from the Control Party or the Property Trustee, as
the case may be, in writing, a list, in such form as the Control Party or the
Property Trustee, as the case may be, may reasonably require, of the names and
addresses of the Securityholders as of a date not more than 15 days prior to the
time such list is furnished; provided, that the Administrative Trustees shall
not be obligated to provide such list at any time such list does not differ from
the most recent list given to the Control Party and the Property Trustee by the
Administrative Trustees or at any time the Property Trustee is the Securities
Registrar. If one or more Holders of Trust Securities Certificates evidencing
not less than 25% of the Outstanding Liquidation Amount apply in writing to the
Administrative Trustees, and such application states that the applicants desire
to communicate with other Securityholders with respect to their rights under
this Trust Agreement or under the Trust Securities Certificates and such
application is accompanied by a copy of the communication that such applicants
propose to transmit, then the Administrative Trustees shall, within five
Business Days after the receipt of such application, afford such applicants
access during normal business hours to the current list of Securityholders. Each
Holder, by receiving and holding a Trust Securities Certificate, and each Owner
shall be deemed to have agreed not to hold either the Control Party or the
Administrative Trustees accountable by reason of the disclosure of its name and
address, regardless of the source from which such information was derived.

surrendered for registration of transfer or exchange and where notices and
demands to or upon the Trustees in respect of the Trust Securities Certificates
may be served. The Administrative Trustees initially designate
____________________, New York, New York _____, as its principal agency for such
purposes. The Administrative Trustees shall give prompt written notice to the
Control Party and to the Securityholders of any change in the location of the
Securities Register or any such office or agency.

          Section 5.09    Appointment of Paying Agent.  The Paying Agent shall 
                          ---------------------------
make Distributions and other payments provided hereby to Securityholders from
the Payment Account and shall report the amounts of such Distributions and
payments to the Property Trustee and the Administrative Trustees. Any Paying
Agent shall have the revocable power to withdraw funds from the Payment Account
for the purpose of making the Distributions and payments provided hereby. The
Administrative Trustees may revoke such power and remove the Paying Agent if
such Trustees determine in their sole discretion that the Paying Agent shall
have failed to perform its obligations under this 

                                       24

Property Trustee, and it may choose any co-paying agent that is acceptable to
the Administrative Trustees and the Control Party. Any Person acting as Paying
Agent shall be permitted to resign as Paying Agent upon 30 days' written notice
to the Administrative Trustees and the Control Party. In the event that a Paying
Agent shall resign or be removed, the Administrative Trustees shall appoint a
successor that is acceptable to the Control Party to act as Paying Agent (which
shall be a bank or trust company). The Administrative Trustees shall cause such
successor Paying Agent or any additional Paying Agent appointed by the
Administrative Trustees to execute and deliver to the Trustees an instrument in
which such successor Paying Agent or additional Paying Agent shall agree with
the Trustees that as Paying Agent, such successor Paying Agent or additional
Paying Agent will hold all sums, if any, held by it for payment to the
Securityholders in trust for the benefit of the Securityholders entitled thereto
until such sums shall be paid to such Securityholders. The Paying Agent shall
return all unclaimed funds to the Property Trustee and upon removal of a Paying
Agent such Paying Agent shall also return all funds in its possession to the
Property Trustee. The provisions of Sections 9.01, 9.03 and 9.06 shall apply to
the Property Trustee also in its role as Paying Agent, for so long as the
Property Trustee shall act as Paying Agent and, to the extent applicable, to any
other paying agent appointed hereunder. Any reference in this Agreement to the
Paying Agent shall include any co-paying agent unless the context requires
otherwise.

Securities, upon original issuance, will be issued in the form of typewritten
Book-Entry Trust Securities Certificates, to be delivered to or held on behalf
of The Depository Trust Company, the initial Clearing Agency, by, or on behalf
of, the Trust. Such Book-Entry Trust Securities Certificate or Certificates

Co., the nominee of the initial Clearing Agency, and no Owner or other
beneficial owner will receive a Definitive Trust Securities Certificate

     effect;

          (ii)   the Securities Registrar and the Trustees shall be entitled to

     Book-Entry Trust Securities) as the sole Holder of Book-Entry Trust
     Securities Certificates and shall have no obligations to the Owners
     thereof;

          (iii)    to the extent that the provisions of this Section conflict
     with any other provisions of this Trust Agreement, the provisions of this
     Section shall control; and

          (iv)     the rights of the Owners of the Book-Entry Trust Securities
     Certificates shall be exercised only through the Clearing Agency and shall
     be limited to those established by law and agreements between such Owners
     and the Clearing Agency and/or the Clearing Agency Participants.  Pursuant
     to the Certificate Depository Agreement, unless and until Definitive Trust
     Securities Certificates are issued pursuant to Section 5.12, the Clearing
     Agency will make book-entry transfers among the Clearing Agency
     Participants and receive and transmit payments on the Trust Securities to
     such Clearing Agency Participants.

unless and until Definitive Trust Securities Certificates shall have been issued
to Owners pursuant to Section 5.12, the Trustees shall give all such notices and
communications specified herein to be given to Owners to the Clearing Agency,
and shall have no obligations to the Owners.

of the Trust Securities or the Control Party fails to pay any amounts due and
payable in respect of the Trust Securities or the Control Party fails to pay any
amounts payable in respect of the Guarantee, as required by their respective
terms, upon surrender to the Administrative Trustees of the Book-Entry Trust
Securities Certificates representing the Trust Securities by the Clearing
Agency, accompanied by registration instructions, the Administrative Trustees or
any one of them shall execute and authenticate Definitive Trust Securities
Certificates representing the Trust Securities in accordance with the
instructions of the Clearing Agency. Neither the Securities Registrar nor the
Trustees shall be liable for any delay in delivery of such instructions and may
conclusively rely on, and shall be protected in relying on, such instructions.
Upon the issuance of Definitive Trust Securities Certificates, the Trustees
shall recognize the Holders of the Definitive Trust Securities Certificates as
Securityholders. The Definitive Trust Securities Certificates shall be printed,
lithographed or engraved or may be produced in any other manner as is reasonably
acceptable to the Administrative Trustees, as evidenced by the execution thereof
by the Administrative Trustees or any one of them.

such) in accordance with Section 2.09, and the Securityholders shall not have
any right or title therein other than the undivided beneficial ownership
interest in the assets of the Trust conferred by their Trust Securities, and
they shall have no right to call for any partition or division of property,
profits or rights of the Trust except as described below. The Trust Securities
shall be personal property giving only the rights specifically set forth therein

of the purchase price therefor, will be fully paid and nonassessable by the
Trust. The Control Party and the Holders of the Trust Securities shall be
entitled to the same limitation of personal liability extended to stockholders
of private corporations for profit organized under the General Corporation Law
of the State of Delaware.

the obligations of the parties hereto, nor shall anything herein set forth, or
contained in the terms of the Trust Securities Certificates and the Control
Certificate, be construed so as to constitute the Securityholders and the
Control Party, respectively, from time to time as partners or members of an
association. In each case where the Holders of the Trust Securities are entitled
to vote, the Control Party shall not be entitled to vote.

          (b)   So long as any Junior Subordinated Debentures are held by or for
the benefit of the Property Trustee, the 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 which is waivable under Section ___ of
the Subordinated 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
Subordinated Indenture or the Junior Subordinated Debentures, where such consent
shall be required, or to any other action, under the Subordinated Indenture,
without, in each case, obtaining the prior approval of the Holders of at least a
majority in aggregate Liquidation Amount of all Outstanding Trust Securities;
provided, however, that where a consent under the Subordinated Indenture would
require the consent of each holder of Junior Subordinated Debentures affected
thereby, no such consent shall be given by the Trustees without the prior
written consent of each Holder of Trust Securities. The Trustees shall not
revoke any action previously authorized or approved by a vote of the Holders of
Trust Securities except by subsequent vote of the Holders of Trust Securities.
The Property Trustee shall notify all Holders of the 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 Trustees shall, at
the expense of the US Affiliates pursuant to the Expense Agreement, obtain an
Opinion of Counsel designated by the Control Party who is experienced in such
matters to the effect that (A) the Trust will not be classified as other than a
grantor trust for United States federal income tax purposes on account of such
action, (B) the Trust will fall within the provisions of Section 60 and will not
be classified as a company, in either case, for purposes of United Kingdom tax
law, on account of such action and (C) 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.

          Section 7.03    Meetings of Securityholders.  No annual meeting of 
                          ---------------------------
Securityholders is required to be held. The Administrative Trustees, however,
shall call a meeting of Securityholders to vote on any matter upon the written
request of the Securityholders of record of 25% of the Outstanding Trust
Securities (based upon their aggregate Liquidation Amount) and the
Administrative Trustees or the Property Trustee may, at any time in their
discretion, call a meeting of Securityholders to vote on any matters as to which
Securityholders are entitled to vote.

          Securityholders of record of 50% of the Outstanding Trust Securities
(based upon their aggregate Liquidation Amount), present in person or by proxy,
shall constitute a quorum at any meeting of Securityholders.

          If a quorum is present at a meeting, an affirmative vote by the
Securityholders of record present, in person or by proxy, holding more than 66-
2/3% of the Securities (based upon their aggregate Liquidation Amount) held by
the Trust Securityholders of record present, either in person or by proxy, at
such meeting shall constitute the action of the Securityholders, unless this
Trust Agreement requires a greater or lesser number of affirmative votes.

          Section 7.04    Voting Rights.  In respect of any matter as to which 
                          -------------
Trust Securityholders are entitled to vote, Trust Securityholders shall be
entitled to one vote for each $25 of Liquidation Amount represented by their
Trust Securities.

          Section 7.05    Proxies, etc.  At any meeting of Securityholders, 
                          -------------
any Securityholder entitled to vote may vote by proxy, provided that no proxy
shall be voted at any meeting unless it shall have been placed on file with the
Administrative Trustees, or with such other officer or agent of the Trust as the
Administrative Trustees may direct, for verification prior to the time at which
such vote shall be taken. Pursuant to a resolution of the Property Trustee,
proxies may be solicited in the name of the Property Trustee or one or more
officers of the Property Trustee. Only Securityholders of record shall be
entitled to vote. When Trust Securities are held jointly by several Persons, any
one of them may vote at any meeting in person or by proxy in respect of such
Trust Securities, but if more than one of them shall be present at such meeting
in person or by proxy, and such joint owners or their proxies so present
disagree as to any vote to be cast, such vote shall not be received in respect
of such Trust Securities. A proxy purporting to be executed by or on behalf of a
Securityholder shall be deemed valid unless challenged at or prior to its
exercise, and the burden of proving invalidity shall rest on the challenger. No
proxy shall be valid more than three years after its date of execution.

          Section 7.06    Securityholder Action by Written Consent. Any action 
                          -----------------------------------------
which may be taken by Securityholders at a meeting may be taken without a
meeting if Securityholders holding at least 66-2/3% of all Outstanding Trust
Securities entitled to vote in respect of such action (or such other proportion
thereof as shall be required by any express provision of this Trust Agreement)
shall consent to the action in writing (based upon their aggregate Liquidation
Amount).

          Section 7.07    Record Date for Voting and Other Purposes.  For the 
                          -----------------------------------------
purposes of determining the Securityholders who are entitled to notice of and to
vote at any meeting or by written consent, or to participate in any Distribution
on the Trust Securities in respect of which a record date is not otherwise
provided for in this Trust Agreement, or for the purpose of any other action,
the Administrative Trustees may from time to time fix a date, not more than 90
days prior to the date of any meeting of Securityholders or the payment of
Distribution or other action, as the case may be, as a record date for the
determination of the identity of the Securityholders of record for such
purposes.

          Section 7.08    Acts of Securityholders.  Any request, demand, 
                          -----------------------
authorization, direction, notice, consent, waiver or other action provided or
permitted by this Trust Agreement to be given, made or taken by Securityholders
or the Control Party may be embodied in and evidenced by one or more instruments
of substantially similar tenor signed by such Securityholders or the Control
Party in person or by an agent appointed in writing; and, except as otherwise
expressly provided herein, such action shall become effective when such
instrument or instruments are delivered to the Administrative Trustees. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Securityholders or
the Control Party signing such instrument or instruments. Proof of execution of
any such instrument or of a writing appointing any such agent shall be
sufficient for any purpose of this Trust Agreement and (subject to Section 9.01)
conclusive in favor of the Trustees, if made in the manner provided in this
Section.

          The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof.  Where
such execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority.  The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which the Trustees deem sufficient.

          The ownership of Trust Securities shall be proved by the Securities
Register.

          Any request, demand, authorization, direction, notice, consent, waiver
or other Act of the Securityholder of any Trust Security shall bind every future
Securityholder of the same Trust Security and the Securityholder of every Trust
Security issued upon the registration of transfer thereof or in exchange
therefor or in lieu thereof in respect of anything done, omitted or suffered to
be done by the Trustees or the Trust in reliance thereon, whether or not
notation of such action is made upon such Trust Security.

          Without limiting the foregoing, a Securityholder entitled hereunder to
take any action hereunder with regard to any particular Trust Security may do so
with regard to all or any part of the Liquidation Amount of such Trust Security
or by one or more 

                                       30
<PAGE>
 
duly appointed agents each of which may do so pursuant to such appointment with
regard to all or any part of such Liquidation Amount.

          Section 7.09    Inspection of Records.  Upon reasonable notice to 
                          ---------------------
the Trustees, the records of the Trust shall be open to inspection by
Securityholders during normal business hours for any purpose reasonably related
to such Securityholder's interest as a Securityholder.

                                  THE TRUSTEES

          Section 9.01    Certain Duties and Responsibilities.
                          ----------------------------------- 

          (a)   The rights, duties and responsibilities of the Trustees shall be
as provided by this Trust Agreement and, in the case of the Property Trustee,
the Trust Indenture Act.  Notwithstanding the foregoing, no provision of this
Trust Agreement shall require the Trustees to expend or risk their own funds or
otherwise incur any financial liability in the performance of any of their
duties hereunder, or in the exercise of any of their rights or powers, if they
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
them.  Whether or not therein expressly so provided, every provision of this
Trust Agreement relating to the conduct or affecting the liability of or
affording protection to the Trustees shall be subject to the provisions of this
Section.

          (b)   All payments made by the Property Trustee in respect of the
Trust Securities shall be made only from the income and proceeds from the Trust
Property and only to the extent that there shall be sufficient income or
proceeds from the Trust Property to enable the Property Trustee to make payments
in accordance with the terms hereof.  Each Securityholder, by its acceptance of
a Trust Security, agrees that it will look solely to the income and proceeds
from the Trust Property to the extent available for distribution to it as herein
provided and that the Trustees are not personally liable to it for 

                                       32
<PAGE>
 
any amount distributable in respect of any Trust Security or for any other
liability in respect of any Trust Security. This Section 9.01(b) does not limit
the liability of the Trustees expressly set forth elsewhere in this Trust
Agreement or, in the case of the Property Trustee, in the Trust Indenture Act.

          Section 9.02    Notice of Defaults and Extension Periods.  (a) Within
                          ----------------------------------------
90 days after the occurrence of any Event of Default, the Property Trustee shall
transmit, in the manner and to the extent provided in Section 11.08, notice of
any Event of Default actually known to a Responsible Officer of the Property
Trustee to the Securityholders, the Administrative Trustees, the Control Party
and the Depositor, unless such Event of Default shall have been cured or waived.
For purposes of this Section, the term "Event of Default" means any event that
is, or after purposes of this Section, the terms "Event of Default" means any
event that is, or after notice or lapse of time or both would become, an Event
of Default.

          (b) The Property Trustee shall transmit, to the Securityholders in the

                          ----------------------------------
provisions of Section 9.01 and except as provided by law:


          (i)    the Property Trustee may conclusively rely and shall be
     protected in acting or refraining from acting in good faith upon any
     resolution, Opinion of Counsel, certificate, written representation of a
     Holder or transferee, certificate of auditors or any other certificate,
     statement, instrument, opinion, report, notice, request, consent, order,
     appraisal, bond or other paper or document believed by it to be genuine and
     to have been signed or presented by the proper party or parties;

          (ii)   if (A) in performing its duties under this Trust Agreement the
     Property Trustee is required to decide between alternative courses of
     action, or (B) in construing any of the provisions in this Trust Agreement
     the Property Trustee finds the same ambiguous or inconsistent with any
     other provisions contained herein, or (C) the Property Trustee is unsure of
     the application of any provision of this Trust Agreement, then, except as
     to any matter as to which the Trust Securityholders are entitled to vote
     under the terms of this Trust Agreement, the Property Trustee shall deliver
     a notice to the Control Party requesting written instructions of the
     Control Party as to the course of action to be taken.  The Property Trustee
     shall take such action, or refrain from taking such action, as the Property
     Trustee shall be instructed in writing to take, or to refrain from taking,
     by the Control Party; provided, however, that if the Property Trustee does
     not receive such instructions of the Control Party within ten Business Days
     after it has delivered such notice, or such reasonably shorter period of
     time set forth in such notice (which to the extent practicable shall not be
     less than two Business Days), it may, but shall be under no duty to, take
     or refrain from taking such action not 

                                       33
<PAGE>
 
     inconsistent with this Trust Agreement as it shall deem advisable and in
     the best interests of the Securityholders, in which event the Property
     Trustee shall have no liability except for its own bad faith, negligence or
     willful misconduct;

          (iii)    the Property Trustee may consult with counsel of its
     selection and the advice of such counsel or any Opinion of Counsel shall be
     full and complete authorization and protection in respect of any action
     taken, suffered or omitted by it hereunder in good faith and in reliance
     thereon;

          (iv)     the Property Trustee shall be under no obligation to exercise
     any of the rights or powers vested in it by this Trust Agreement at the
     request or direction of any of the Securityholders pursuant to this Trust
     Agreement, unless such Securityholders shall have offered to the Property
     Trustee reasonable security or indemnity against the costs, expenses and
     liabilities which might be incurred by it in compliance with such request
     or direction;

          (v)      the Property Trustee shall not be bound to make any
     investigation into the facts or matters stated in any resolution,
     certificate, statement, instrument, opinion, report, notice, request,
     consent, order, approval, bond or other document, unless requested in
     writing to do so by one or more Securityholders; and

          (vi)     the Property Trustee may execute any of the trusts or powers
     hereunder or perform any duties hereunder either directly or by or through
     its agents or attorneys, provided that the Property Trustee shall be
     responsible for its own negligence or recklessness with respect to
     selection of any agent or attorney appointed by it hereunder.

          Section 9.04    Not Responsible for Recitals or Issuance of Securities
                          ------------------------------------------------------
The recitals contained herein and in the Trust Securities Certificates shall
be taken as the statements of the Trust, and the Trustees do not assume any
responsibility for their correctness.  The Trustees shall not be accountable for
the use or application by the Trust of the proceeds of the Trust Securities in
accordance with Section 2.05.

          The Property Trustee may conclusively assume that any funds held by it
hereunder are legally available unless a Responsible Officer shall have received
written notice from the Company, any Holder or any other Trustee that such funds
are not legally available.

          Section 9.05    May Hold Securities. Any Trustee or any other agent 
                          -------------------
of the Trustees or the Trust, in its individual or any other capacity, may
become the owner or pledgee of Trust Securities and, except as provided in the
definition of the term "Outstanding" in Article I and subject to Sections 9.08
and 9.13, may otherwise deal with the Trust with the same rights it would have
if it were not a Trustee or such other agent.

          Section 9.06    Compensation; Fees; Indemnity.
                          ----------------------------- 

          The following expenses will be paid pursuant to the Expense Agreement:

                                       34
<PAGE>
 
          (1)   the payment to the Trustees from time to time of reasonable
compensation, as agreed to in writing from time to time, for all services
rendered by the Trustees hereunder (which compensation shall not be limited by
any provision of law in regard to the compensation of a trustee of an express
trust);

          (2)   except as otherwise expressly provided herein, the reimbursement
of the Trustees upon request for all reasonable expenses, disbursements and

negligence or bad faith; and

          (3)   the indemnification of the Trustees for any and all loss,
damage, claims, liability or expense incurred without willful misconduct,

expenses of defending themselves against any claim or liability in connection
with the exercise or performance of any of their powers or duties hereunder.

          The provisions of this Section 9.06 shall survive the termination of
this Trust Agreement.

          Section 9.07    Trustees Required; Eligibility.
                          ------------------------------ 

          (a)   There shall at all times be a Property Trustee hereunder with
respect to the Trust Securities.  The Property Trustee shall be a Person that
has a combined capital and surplus of at least $50,000,000.  If any such Person
publishes reports of condition at least annually, pursuant to law or to the
requirements of its supervising or examining authority, then for the purposes of
this Section, the combined capital and surplus of such Person shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published.  If at any time the Property Trustee with respect to the
Trust Securities shall cease to be eligible in accordance with the provisions of
this Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

          (b)   There shall at all times be one or more Administrative Trustees
hereunder with respect to the Trust Securities.  Each Administrative Trustee
shall be either a natural person who is at least 21 years of age or a legal
entity that shall act through one or more persons authorized to bind such

          Section 9.08    Conflicting Interests.  If the Property Trustee has 
                          ---------------------
or shall acquire a conflicting interest within the meaning of the Trust
Indenture Act, the Property 

                                       35
<PAGE>
 
Trustee shall either eliminate such interest or resign, to the extent and in the
manner provided by, and subject to the provisions of, the Trust Indenture Act
and this Trust Agreement. To the extent permitted by the Trust Indenture Act,
the Property Trustee shall not be deemed to have a conflicting interest by
virtue of being trustee under the Guarantee or the Subordinated Indenture.

          Section 9.09    Co-Trustees and Separate Trustee.  Unless an 
                          --------------------------------
Indenture Event of Default shall have occurred and be continuing, at any time or
times, for the purpose of meeting the legal requirements of the Trust Indenture
Act or of any jurisdiction in which any part of the Trust Property may at the
time be located, the Control Party and the Property Trustee shall have power to
appoint, and upon the written request of the Property Trustee, the Control Party
shall for such purpose join with the Property Trustee in the execution, delivery
and performance of all instruments and agreements necessary or proper to
appoint, one or more Persons approved by the Property Trustee either to act as
co-trustee, jointly with the Property Trustee, of all or any part of such Trust
Property, or to act as separate trustee of any such Trust Property, in either
case with such powers as may be provided in the instrument of appointment, and
to vest in such Person or Persons in the capacity aforesaid, any property,
title, right or power deemed necessary or desirable, subject to the other
provisions of this Section. If the Control Party does not join in such
appointment within 15 days after the receipt by it of a request so to do, or in
case an Indenture Event of Default has occurred and is continuing, the Property
Trustee alone shall have power to make such appointment. Any co-trustee or
separate trustee appointed pursuant to this Section must satisfy the
requirements of Section 9.07.

          Should any written instrument from the Depositor be required by any
co-trustee or separate trustee so appointed for more fully confirming to such
co-trustee or separate trustee such property, title, right, or power, any and
all such instruments shall, on request, be executed, acknowledged, and delivered
by the Depositor.

          Every co-trustee or separate trustee shall, to the extent permitted by
law, but to such extent only, be appointed subject to the following terms,
namely:

          (i)    The Trust Securities shall be executed, authenticated and
     delivered and all rights, powers, duties, and obligations hereunder in
     respect of the custody of securities, cash and other personal property held
     by, or required to be deposited or pledged with, the Trustees hereunder,
     shall be exercised, solely by the Trustees and not by such co-trustee or
     separate trustee.

          (ii)   The rights, powers, duties, and obligations hereby conferred or
     imposed upon the Property Trustee in respect of any property covered by
     such appointment shall be conferred or imposed upon and exercised or
     performed by the Property Trustee or by the Property Trustee and such co-
     trustee or separate trustee jointly, as shall be provided in the instrument
     appointing such co-trustee or separate trustee, except to the extent that
     under any law of any jurisdiction in which any particular act is to be
     performed, the Property Trustee shall be incompetent or unqualified to
     perform such act, in which event such rights, 

                                       36

     powers, duties, and obligations shall be exercised and performed by such 
     co-trustee or separate trustee.

          (iii)    The Property Trustee at any time, by an instrument in writing
     executed by it, with the written concurrence of the Control Party, may
     accept the resignation of or remove any co-trustee or separate trustee
     appointed under this Section, and, in case an Indenture Event of Default
     has occurred and is continuing, the Property Trustee shall have power to
     accept the resignation of, or remove, any such co-trustee or separate
     trustee without the concurrence of the Control Party.  Upon the written
     request of the Property Trustee, the Control Party shall join with the
     Property Trustee in the execution, delivery, and performance of all
     instruments and agreements necessary or proper to effectuate such
     resignation or removal.  A successor to any co-trustee or separate trustee
     so resigned or removed may be appointed in the manner provided in this
     Section.

          (iv)   No co-trustee or separate trustee hereunder shall be personally
     liable by reason of any act or omission of the Property Trustee, or any
     other such trustee hereunder.

          (v)   The Trustees shall not be liable by reason of any act of a co-
     trustee or separate trustee.

          (vi)   Any Act of Holders delivered to the Property Trustee shall be
     deemed to have been delivered to each such co-trustee and separate trustee.

          Section 9.10    Resignation and Removal; Appointment of Successor. No
                          -------------------------------------------------
resignation or removal of any Trustee (the "Relevant Trustee") and no
appointment of a successor Relevant Trustee pursuant to this Article shall
become effective until the acceptance of appointment by the successor Relevant
Trustee in accordance with the applicable requirements of Section 9.11.

          Subject to the immediately preceding paragraph, the Relevant Trustee
may resign at any time by giving written notice thereof to the Securityholders.
If the instrument of acceptance by a successor Relevant Trustee required by
Section 9.11 shall not have been delivered to the Relevant Trustee within 30
days after the giving of such notice of resignation, the resigning Relevant
Trustee may petition any court of competent jurisdiction for the appointment of
a successor Relevant Trustee.

          Unless an Indenture Event of Default shall have occurred and be
continuing, the Property Trustee or Delaware Trustee may be removed at any time
by Act of the Control Party.  If an Indenture Event of Default shall have
occurred and be continuing, the Property Trustee or Delaware Trustee may be
removed at such time by Act of the Securityholders of a majority in aggregate
Liquidation Amount of the Trust Securities, delivered to the Property Trustee
(in its individual capacity and on behalf of the Trust).

          An Administrative Trustee may be removed by the Control Party at any
time.  In no event will the Securityholders have the right to vote, appoint,
remove or 

                                       37
<PAGE>
 
replace the Administrative Trustees, which rights are vested exclusively with
the Control Party, as holder of the Control Certificate.

          If the Relevant Trustee shall resign, be removed or become incapable
of continuing to act as Trustee, or if a vacancy shall occur in the office of
the Relevant Trustee for any cause, at a time when no Indenture Event of Default
shall have occurred and be continuing, the Control Party shall promptly appoint
a successor Relevant Trustee or Trustees, and the retiring Relevant Trustee
shall comply with the applicable requirements of Section 9.11.  If the Property
Trustee or Delaware Trustee shall resign, be removed or become incapable of
continuing to act as the Property Trustee or Delaware Trustee at a time when an
Indenture Event of Default shall have occurred and be continuing, the Holders of
Trust Securities, by Act of the Securityholders of a majority in Liquidation
Amount of the Trust Securities then Outstanding delivered to the retiring
Property Trustee or Delaware Trustee, shall promptly appoint a successor
Property Trustee or Delaware Trustee, and such appointee must comply with the
applicable requirements of Section 9.11.  If no successor Relevant Trustee shall
have been so appointed in accordance with this Section 9.10 and accepted
appointment in the manner required by Section 9.11, any Securityholder who has
been a Securityholder of Trust Securities for at least six months may, on behalf
of himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Relevant Trustee.

          The retiring Relevant Trustee shall give notice of each resignation
and each removal of the Relevant Trustee, and each appointment of a successor
Trustee to all Securityholders in the manner provided in Section 11.08 and shall
give notice to the Control Party.  Each notice shall include the name of the
successor Relevant Trustee and the address of its Corporate Trust Office if it
is the Property Trustee.

          Notwithstanding the foregoing or any other provision of this Trust
Agreement, in the event any Administrative Trustee or a Delaware Trustee who is
a natural person dies or becomes incompetent or incapacitated or resigns, the
vacancy created by such death, incompetence or incapacity or resignation may be
filled by (i) the unanimous act of the remaining Administrative Trustee or
Trustees or (ii) otherwise by the Control Party (with the successor in each case
being an individual who satisfies the eligibility requirement for Administrative
Trustees set forth in Section 9.07).

          Section 9.11    Acceptance of Appointment by Successor.  In case of 
                          --------------------------------------
the appointment hereunder of a successor Relevant Trustee, every such successor
Relevant Trustee so appointed shall execute, acknowledge and deliver to the
Trust and to the retiring Relevant Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Relevant
Trustee shall become effective and such successor Relevant Trustee, without any
further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the retiring Relevant Trustee; but, on the request
of the Control Party or the successor Relevant Trustee, such retiring Relevant
Trustee shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor 

                                       38
<PAGE>
 
Relevant Trustee all the rights, powers and trusts of the retiring Relevant
Trustee and shall duly assign, transfer and deliver to such successor Relevant
Trustee all property and money held by such retiring Relevant Trustee hereunder.

          Upon request of any such successor Relevant Trustee, the Trust shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Relevant Trustee all such rights, powers and trusts
referred to in the preceding paragraph.

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

          Section 9.12    Merger, Conversion, Consolidation or Succession to
                          --------------------------------------------------
Business.  Any Person into which the Property Trustee, Delaware Trustee or any
- --------
Administrative Trustee which is not a natural person may be merged or converted
or with which it may be consolidated, or any Person resulting from any merger,
conversion or consolidation to which such Relevant Trustee shall be a party, or
any Person succeeding to all or substantially all the corporate trust business
of such Relevant Trustee, shall be the successor of such Relevant Trustee
hereunder, provided such Person shall be otherwise qualified and eligible under
this Article, without the execution or filing of any paper or any further act on
the part of any of the parties hereto.

          Section 9.13    Preferential Collection of Claims Against Certain
                          -------------------------------------------------
Entities.  If and when the Property Trustee shall be or become a creditor of 
- --------
the Control Party, Yorkshire Finance, Yorkshire Group or the Trust (or any other
obligor upon the Junior Subordinated Debentures or the Trust Securities), the
Property Trustee shall be subject to the provisions of the Trust Indenture Act
regarding the collection of claims against the Depositor or Trust (or any such
other obligor). For purposes of Section 311(b)(4) and (6) of the Trust Indenture
Act:

          (a)   "cash transaction" means any transaction in which full payment
for goods or securities sold is made within seven days after delivery of the
goods or securities in currency or in checks or other orders drawn upon banks or
bankers and payable upon demand; and

          (b)   "self-liquidating paper" means any draft, bill of exchange,
acceptance or obligation which is made, drawn, negotiated or incurred by the
Control Party, Yorkshire Finance, Yorkshire Group or the Trust (or any such
obligor) for the purpose of financing the purchase, processing, manufacturing,
shipment, storage or sale of goods, wares or merchandise and which is secured by
documents evidencing title to, possession of, or a lien upon, the goods, wares
or merchandise or the receivables or proceeds arising from the sale of the
goods, wares or merchandise previously constituting the security, provided the
security is received by the Property Trustee simultaneously with the creation of
the creditor relationship with the Control Party, Yorkshire Finance, Yorkshire
Group or the Trust (or any such obligor) arising from the making, drawing,
negotiating or incurring of the draft, bill of exchange, acceptance or
obligation.

Trustee shall transmit a brief report dated as of such May 15 with respect to

Property Trustee such documents, reports and information as required by Section
314 of the Trust Indenture Act (if any) and, within 120 days after the end of
each fiscal year of the Control Party, the compliance certificate required by
Section 314(a)(4) of the Trust Indenture Act in the form and in the manner
required by Section 314 of the Trust Indenture Act.

          Section 9.16    Evidence of Compliance with Conditions Precedent.
                          ------------------------------------------------

shall provide to the Property Trustee such evidence of compliance with any
conditions precedent, if any, provided for in this Trust Agreement that relate
to any of the matters set forth in Section 314(c) of the Trust Indenture Act.
Any certificate or opinion required to be given pursuant to Section 314(c)(1) of
the Trust Indenture Act shall comply with Section 314(e) of the Trust Indenture
Act.

          Section 9.17    Number of Trustees.
                          ------------------ 

          (a)   The number of Trustees shall initially be six, provided that the
Control Party by written instrument may increase or decrease the number of
Administrative Trustees.

          (b)   If a Trustee ceases to hold office for any reason and the number
of Administrative Trustees is not reduced pursuant to Section 9.17(a), or if the
number of Trustees is increased pursuant to Section 9.17(a), a vacancy shall

Section 9.10.

          (c)   The death, resignation, retirement, removal, bankruptcy,
incompetence or incapacity to perform the duties of a Trustee shall not operate
to dissolve, terminate or annul the Trust.  Whenever a vacancy in the number of
Administrative Trustees shall occur, until such vacancy is filled by the
appointment of an Administrative Trustee in accordance with Section 9.10, the
Administrative Trustees in office, regardless of their number (and
notwithstanding any other provision of this Trust Agreement), shall have all
powers granted to the Administrative Trustees and shall discharge the duties
imposed upon the Administrative Trustees by this Trust Agreement.

          Section 9.18    Delegation of Power.
                          ------------------- 

          (a)   Any Administrative Trustee may, by power of attorney consistent
with applicable law, delegate to any other natural person over the age of 21 his
or her power for the purpose of executing any documents contemplated in Section
2.07(A), including any registration statement or amendment thereto filed with
the Commission, or making any other governmental filing; and

          (b)   The Administrative Trustees shall have power to delegate from
time to time to such of their number the doing of such things and the execution
of such instruments either in the name of the Trust or the names of the
Administrative Trustees or otherwise as the Administrative Trustees may deem
expedient, to the extent such delegation is not prohibited by applicable law or
contrary to the provisions of the Trust, as set forth herein.

          Section 9.19    Enforcement of Rights of Property Trustee by
                          --------------------------------------------
Securityholders.  If an Event of Default occurs and is continuing, then the 
- ---------------
Holders of Trust Securities will rely on the enforcement by the Property
Trustee, as the holder of the Junior Subordinated Debentures, of its rights
against Yorkshire Finance and Yorkshire Group. In addition, the Holders of a
majority in aggregate Liquidation Amount of the Trust Securities will have the
right to direct the time, method, and place of conducting any proceeding for any
remedy available to the Property Trustee or to direct the exercise of any trust
or power conferred upon the Property Trustee under this Trust Agreement,
including the right to direct the Property Trustee to exercise the remedies
available to it as a holder of the Junior Subordinated Debentures, provided that
such direction shall not be in conflict with any rule of law or with this Trust
Agreement, and could not involve the Property Trustee in personal liability in
circumstances where reasonable indemnity would not be adequate. If the Property
Trustee fails to enforce its rights under the Junior Subordinated Debentures, a
Holder of Trust Securities may, to the fullest extent permitted by applicable
law, institute a legal proceeding against Yorkshire Finance or Yorkshire Group
or both to enforce its rights under this Trust Agreement without first
instituting any legal proceeding against the Property Trustee or any other
Person, including the Trust; it being understood and intended that no one or
more of such Holders shall have any right in any manner whatsoever by virtue of,
or by availing of, any provision of this Trust Agreement to affect, disturb or
prejudice the rights of any other of such Holders or to obtain or to seek to
obtain priority or preference over any other of such Holders or to enforce any
right under this Trust Agreement, except in the manner herein provided and for
the equal and ratable benefit of all such Holders. Notwithstanding the
foregoing, a Holder of Trust Securities may institute a legal proceeding
directly against Yorkshire Finance or Yorkshire Group or both, without first
instituting a legal proceeding against or requesting or directing that action be
taken by the Property Trustee or any other Person, for enforcement of payment to
such Holder of principal of or interest on the Junior Subordinated Debentures
having a principal amount equal to the aggregate stated liquidation amount of
the Trust Securities of such Holder on or after the due dates therefor specified
or provided for in the Junior Subordinated Debentures. Yorkshire Finance or
Yorkshire Group shall be subrogated to all rights of the Holders of Trust
Securities in respect of any amounts paid to such Holders by Yorkshire Finance
or 

                                       41
<PAGE>
 
Yorkshire Group pursuant to this Section. Any amount received by a Holder or
any related owner from Yorkshire Finance or Yorkshire Group under the Indenture
shall reduce by such amount the Trust's obligations to such Holder thereunder in
respect of which such amount was paid under the Indenture.

automatically dissolve on _________, 2043 (the "Expiration Date") or earlier
pursuant to Section 10.02.

                           -----------------
of the following events (such first occurrence, an "Early Termination Event"),
the Trust shall be dissolved in accordance with the terms hereof:

          (i)    the occurrence of a Bankruptcy Event in respect of Yorkshire
     Finance, dissolution or liquidation of Yorkshire Finance, or the
     dissolution of the Trust pursuant to a judicial decree;

          (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 The Control Party) and to
     distribute the Junior Subordinated Debentures to Securityholders in
     liquidation of the Trust as provided in Section 10.04; and

          (iii)  the payment at maturity or redemption of all of the Junior
     Subordinated Debentures and the consequent redemption of all of the Trust
     Securities.

                           -----------
responsibilities of the Trust and the Trustees created hereby shall terminate

Trustee to Securityholders upon the liquidation of the Trust pursuant to Section

4.02, of all amounts or instruments required to be distributed hereunder upon
the final payment of the Trust Securities; (b) the payment of any expenses owed

          Section 10.04    Liquidation.
                           ----------- 

          (a)   If any Early Termination Event specified in clause (i) or (ii)

shall distribute the Junior Subordinated Debentures to the Securityholders as
provided in this Section 10.04.

<PAGE>
 
          (b)   In connection with a distribution of the Junior Subordinated
Debentures, each Holder of Trust Securities shall be entitled to receive, after
the satisfaction (whether by payment or reasonable provision for payment) of
liabilities to creditors of the Trust (as evidenced by a certificate of the
Administrative Trustees), a Like Amount of Junior Subordinated Debentures.
Notice of liquidation shall be given by the Trustees by first-class mail,
postage prepaid, mailed not later than 30 nor more than 60 days prior to the
Liquidation Date to the Holders thereof as they appear on the Securities
Register on the relevant record date which, as long as the trust Securities are
represented by Book-Entry Trust Securities Certificates, shall be one Business
Day prior to the Liquidation Date or, in the event that the Trust Securities are
not so represented, such relevant record date shall be the close of business on
the fifteenth calendar day prior to the Liquidation Date.  All notices of
liquidation shall:

          (i)    state the Liquidation Date;

          (ii)   state that from and after the Liquidation Date, the Trust
     Securities will no longer be deemed to be Outstanding and any Trust
     Securities Certificates not surrendered for exchange will be deemed to
     represent a Like Amount of Junior Subordinated Debentures; and

          (iii)  provide such information with respect to the mechanics by
     which Holders may exchange Trust Securities Certificates for Junior
     Subordinated Debentures as the Administrative Trustees or the Property
     Trustee shall deem appropriate.

          (c)   In order to effect the liquidation of the Trust and distribution
of the Junior Subordinated Debentures to Securityholders, the Property Trustee
shall establish such procedures as it shall deem appropriate to effect the
distribution of Junior Subordinated Debentures in exchange for the Outstanding
Trust Securities Certificates.

          (d)   After the Liquidation Date, (i) the Trust Securities will no
longer be deemed to be Outstanding and the Guarantee will be discharged, (ii)
certificates representing a Like Amount of Junior Subordinated Debentures will
be issued to Holders of Trust Securities Certificates, upon surrender of such
certificates to the Administrative Trustees or their agent for exchange, (iii)
any Trust Securities Certificates not so surrendered for exchange will be deemed
to represent a Like Amount of Junior Subordinated Debentures, accruing interest
at the rate provided for in the Junior Subordinated Debentures from the last
Distribution Date on which a Distribution was made on such Trust Certificates
until such certificates are so surrendered (and until such certificates are so
surrendered, no payments of interest or principal will be made to Holders of
Trust Securities Certificates with respect to such Junior Subordinated
Debentures) and (iv) all rights of Securityholders holding Trust Securities will
cease, except the right of such Securityholders to receive Junior Subordinated
Debentures upon surrender of Trust Securities Certificates.

          (e)   Yorkshire Group will use its reasonable efforts to cause the
Junior Subordinated Debentures that are distributed in exchange for the Trust
Securities to be 

                                       43

listed on such securities exchange as the Trust Securities are then listed. The
Clearing Agency, as the record holder of the Trust Securities, will receive
global book-entry interests 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 the Clearing Agency, 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 such 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.

          Section 10.05    Bankruptcy.  If an Early Termination Event specified
                           ----------
in clause (i) of Section 10.02 has occurred, the Trust shall be dissolved and
liquidated. The Property Trustee shall distribute a Like Amount of the Junior
Subordinated Debentures to the Securityholders as provided in Section 10.04,
unless such distribution is determined by the Administrative Trustees not to be
practical, in which event the Holders will be entitled to receive, out of the
assets of the Trust available for distribution to Securityholders after
satisfaction of liabilities to creditors, an amount equal to the Liquidation
Amount per Trust Security 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
Liquidated Distribution for which the Trust Securities would be entitled.

          Section 11.03    Amendment.
                           --------- 

          (a)   This Trust Agreement may be amended from time to time by the
Trustees, the Control Party and the Depositor, without the consent of any
Securityholders, (i) to cure any ambiguity, correct or supplement any provision

any Person except the Trustee shall assign rights hereunder to a Holder to the
extent such assignment is necessary to exercise such Holder's rights pursuant to

          they conform to the requirements of this Guarantee Agreement;

          (ii) the Trustee shall not be liable for any error of judgment made in

     reasonable grounds for believing that the repayment of such funds or
     liability is not reasonably assured to it under the terms of this Guarantee
     Agreement or adequate indemnity against such risk or liability is not
     reasonably assured to it.

     SECTION 8.07  Consent to Jurisdiction; Appointment of Agent to Accept
     ------------  -------------------------------------------------------
Service of Process
- ------------------

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

     (b) The Guarantor has irrevocably designated, appointed, and empowered CT
Corporation System, acting through its office at 1633 Broadway, New York, New
York 10019, as its designee, appointee and agent to receive, accept and
acknowledge for and on its behalf, and its properties, assets and revenues,
service of any and all legal process, summons, notices and documents which may
be served in any legal action, suit or proceeding brought against the Guarantor
in any United States or state court.  If for any reason such designee, appointee
and agent hereunder shall cease to be available to act as such, the Guarantor
agrees to designate a new designee, appointee and agent in the Borough of
Manhattan, The City of New York on the terms and for the purposes of this
Section 8.07 satisfactory to the Trustee.  The Guarantor further hereby
irrevocably consents and agrees to the service of any and all legal process,
summons, notices and documents in any legal action, suit or proceeding against
the Guarantor by serving a 

                                       14
<PAGE>
 
copy thereof upon the relevant agent for service of process referred to in this
Section 8.07 (whether or not the appointment of such agent shall for any reason
prove to be ineffective or such agent shall accept or acknowledge such service)
or by mailing copies thereof by registered or certified air mail, postage
prepaid, to the Guarantor at its address specified in or designated pursuant to
this Guarantee. The Guarantor agrees that the failure of any such designee,
appointee and agent to give any notice of such service to it shall not impair or
affect in any way the validity of such service or any judgment rendered in any
action or proceeding based thereon. Nothing herein shall in any way be deemed to
limit the ability of the holders of the Trust Securities and the Trustee, to
serve any such legal process, summons, notices and documents in any other manner
permitted by applicable law or to obtain jurisdiction over the Guarantor or
bring legal actions, suits or proceedings against the Guarantor in such other
jurisdictions, and in such manner, as may be permitted by applicable law. The
Guarantor irrevocably and unconditionally waives, to the fullest extent
permitted by law, any objection which it may now or hereafter have to the laying
of venue of any of the aforesaid actions, suits or proceedings arising out of or
in connection with this Guarantee brought in the Supreme Court of New York, New
York County or the United States District Court for the Southern District of New
York and any appellate court from either thereof and hereby further irrevocably
and unconditionally waives and agrees not to plead or claim in any such court
that any such action, suit or proceeding brought in any such court has been
brought in an inconvenient forum.

       (c) To the extent that the Guarantor may in any jurisdiction claim for
itself or its assets immunity (to the extent such immunity may now or hereafter
exist, whether on the grounds of sovereign immunity or otherwise) from suit,
execution, attachment (whether in aid of execution, before judgment or
otherwise) or other legal process (whether through service or notice or
otherwise), and to the extent that in any such jurisdiction there may be
attributed to itself or its assets such immunity (whether or not claimed), the
Guarantor irrevocably agrees with respect to any matter arising under this
Guarantee for the benefit of the Holders from time to time of the Trust
Securities, not to claim, and irrevocably waives, such immunity to the full
extent permitted by the laws of such jurisdiction.

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

     (e)  The obligation of the Guarantor in respect of any sum payable by it to
the holder of a Trust Security shall, notwithstanding any judgment or order in a
currency (the "judgment currency") other than U.S. dollars, be discharged only
to the extent that on the Business Day following receipt by the Holder of such
Trust Security of any sum, adjudged to be so due in the judgment currency, the
Holder of such Trust Security may in accordance with normal banking procedures
purchase U.S. dollars with the judgment currency; if the amount of U.S. dollars
so purchased is less than the sum originally due to the holder of such Trust
Security in the judgment currency (determined in the manner set forth in the
preceding paragraph), the Guarantor agrees, as a separate obligation and
notwithstanding any such judgment, to indemnify the Holder of such 

                                       15
<PAGE>
 
Trust Security against such loss, and if the amount of the U.S. dollars so
purchased exceeds the sum originally due to the Holder of such Trust Security,
such Holder agrees to remit to the Guarantor such excess, provided that such
Holder shall have no obligation to remit any such excess as long as the
Guarantor shall have failed to pay such Holder any obligations due and payable
under such Trust Security, in which case such excess may be applied to such
obligations of the Guarantor under such Trust Security in accordance with the
terms thereof. The foregoing indemnity shall constitute a separate and
independent obligation of the Guarantor and shall continue in full force and
effect notwithstanding any such judgment or order as aforesaid.

     This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

     2.   The Book-Entry Interests shall be issuable only to DTC or successors
          of DTC or their respective nominees. Except as provided in Section
          2.05, no beneficial owner of Interests shall be entitled to receive a
          Definitive Registered Senior Note, and such beneficial owner's
          Interests shall be reflected only in accordance with the procedures of
          DTC as set forth in the Letter of Representations.

     Section 2.03. Registration of Transfer of the Book-Entry Interests.

     The Book-Entry Depositary agrees to maintain at the Book-Entry Depositary's
Corporate Trust Office the Book-Entry Register in which the Book-Entry
Depositary shall (x), prior to the liquidation of the Trust, record the Property
Trustee, as holder for the Trust, as the initial registered owner of the
Book-Entry Interests and (y) upon the liquidation of the Trust and transfer of
the Book-Entry Interests to DTC (i) record Cede & Co., as nominee of DTC, as the
registered owner of the Book-Entry Interests and (ii) record the registration
and transfer of the Book-Entry Interests. Notwithstanding anything contained
herein to the contrary, the Debentures (represented by the Book-Entry Interests)
shall be transferred only pursuant to the Trust Agreement for so long as the
Trust owns the Debentures. The Book-Entry Interests cannot be transferred unless
such transfer is recorded on the Book-Entry Register. The Book-Entry Depositary
shall not constitute the agent of the Issuer for any other purpose and, in
particular, it shall not constitute the agent of the Issuer in relation to any
payments it may make to the Depositary or be authorized to undertake any
obligations on behalf of the Issuer.

     The foregoing paragraph shall not (i) impose an obligation on the
Book-Entry Depositary to record the ownership interests in or transfers of
Interests held by Participants or its successors or Indirect Participants or
(ii) restrict transfers of such Interests held by Participants or Indirect
Participants. The Book-Entry Depositary shall treat the Depositary as the
absolute owner of the Book-Entry Interests for all purposes whatsoever and shall
not be bound or affected by any notice to the contrary, other than an order of a
court having jurisdiction over the Book-Entry Depositary.

the Trust and transfer of the Book-Entry Interests to DTC, (i) by DTC to its
nominee; (ii) by a nominee of DTC to DTC or to another nominee of DTC; or (iii)
by DTC or any nominee to a successor depositary or a nominee of such successor
depositary.

the benefit of the Depositary Subject to Section 3.08, the Book-Entry Depositary
shall not transfer or lend the Global Debentures or any interest therein, except
that the Global Debentures, as a whole and with the Issuer's consent, may be
transferred (i) by the Book-Entry Depositary to a nominee of the Book-Entry
Depositary; (ii) by a nominee of the Book-Entry Depositary to the Book-Entry
Depositary or another nominee of the Book-Entry Depositary; or (iii) by the

writing that the Issuer issue and the Trustee authenticate and deliver
Definitive Registered Debentures in exchange for a series of Global Debentures,
as a whole but not in part, in such names and authorized denominations as the
Book-Entry Depositary shall specify, if: (i) after liquidation of the Trust and
transfer of the Book-Entry Interests to DTC, DTC notifies the Issuer and the
Book-Entry Depositary that it is unwilling or unable to continue to hold the
Book-Entry Interests related to the Global Debentures of such series 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 the Issuer within 120
days; (ii) the Book-Entry Depositary notifies the Issuer under Section 3.08
hereof that it is unwilling or unable to continue as Book-Entry Depositary and
no successor Book-Entry Depositary is appointed within 120 days; or (iii) the
Issuer in its sole discretion executes and delivers to the Trustee an Officers'
Certificate providing that the Global Debentures of such series shall be so
exchangeable. The Book-Entry Depositary agrees that in such event it will
promptly surrender the Global Debentures of such series held by it to the
Trustee in connection with such exchange and request in writing that the Issuer
execute and the Trustee authenticate and deliver without charge Definitive
Registered Debentures, having the same interest rate, if any, and maturity and
having the



                                       6
<PAGE>
 
same terms as the Interests of the requesting owner, in authorized denominations
of $25 and integral multiples thereof and of an aggregate principal amount equal
to such owner's Interests and that such Global Debentures will be canceled upon
issuance of such Definitive Registered Debentures.

     The Global Debentures shall also be exchangeable, in whole or in part, for
Definitive Registered Debentures if there shall have occurred and be continuing

writing that their Interests be exchanged for one or more Definitive Registered
Debentures (an "Optional Definitive Security Request"). Upon receipt of any such
written request, the Book-Entry Depositary shall (i) promptly surrender the
relevant Global Debenture to the Trustee and request in writing that the Issuer
execute and the Trustee authenticate and deliver without charge Definitive
Registered Debentures of the same series, having the same interest rate, if any,
and maturity and having the same terms as the Interests of the requesting owner,
in authorized denominations of $25 and integral multiples thereof and of an
aggregate principal amount equal to such owner's Interests; and (ii) if the
Global Debenture is being exchanged (x) as a whole, then the surrendered Global
Debenture shall be canceled by the Trustee, or (y) in part, then the principal
amount of the surrendered Global Debenture shall be reduced in accordance with
Section 2.09 herein.

issuance of Definitive Registered Debentures will be borne by the Issuer subject
to any exceptions set forth in the Indenture.

case may be, surrender the Global Debentures at a place of payment or such other
place as the Issuer may designate, and deliver such Global Debentures to the
Trustee for cancellation or for reduction of principal amount in accordance with
Sections 2.07 or 2.09 herein, as the case may be.

     Section 2.07. Cancellation.

Representations. The payment date for the Book-Entry Interests for payment of
any principal or interest shall be the same date as the payment date for the
related Global Debentures.

information from its records as the Issuer may reasonably request in writing to
enable the Issuer or its agents to file necessary reports with governmental

shall not be required to) file any such reports necessary to obtain benefits
under any applicable tax treaties for the Depositary or the beneficial owners of
Interests.

Depositary shall be required to pay to the Depositary only amounts (including
Additional Interest and Additional Amounts, if any) received by the Book-Entry
Depositary from the Issuer under the Global Debentures or the Guarantor pursuant
to the Guarantee.

     (d) Neither the Issuer, the Guarantor nor any agent of the Issuer or the
Guarantor (including but not limited to any paying agent) will have any
responsibility or liability for any aspect relating to payments (including
payments of Additional Interest and Additional Amounts, if any) made or to be

     Whenever the principal amount at maturity of the Global Debentures held by
the Book-Entry Depositary is changed by the Trustee as a result of partial
redemption or otherwise, the Book-Entry Depositary shall record on the
Book-Entry Register a corresponding change in the principal amount of the
related Book-Entry Interests and notify the Depositary of such corresponding
change.

     Section 2.10. Record Date.

the Book-Entry Depositary shall receive notice of any action to be taken in
respect of the Book-Entry Interests or Global Debentures, or whenever the

matter, the Book-Entry Depositary shall fix a record date for determination of
the Depositary who shall be entitled to receive payment in respect of the
Book-Entry Interests corresponding to such Global Debentures



                                       8
<PAGE>
 
or to take any such action or to act in respect of any such matter. Subject to
the provisions of this Agreement, only the Depositary who is registered on the
Book-Entry Register at the close of business on such record date shall be
entitled to receive any such payment, to give instructions as to such action or
to act in respect of any such matter.

     Section 2.11. Action in Respect of the Book-Entry Interests or the Global
Debentures.

     (a) Not later than 10 days from receipt by the Book-Entry Depositary of
notice of any solicitation of consents or request for a waiver or other action
with respect to the Book-Entry Interests or the Global Debentures under this
Agreement or the Indenture, the Book-Entry Depositary shall mail to the
Depositary a notice containing (i) such information as is contained in such
notice, (ii) a statement of the record date with respect to such consent, waiver
or other action, (iii) a statement that, on or prior to a specified date (which
specified date may be set no later than 180 days after the record date) (the
"Expiration Date") the Depositary will be entitled, subject to the provisions of
or governing the Book-Entry Interests or Global Debentures, as the case may be,
to instruct the Book-Entry Depositary as to such consent, waiver or such action,
and (iv) a statement specifying the manner in which such instructions may be
given. Upon receipt by the Book-Entry Depositary of instructions from the

Book-Entry Depositary shall endeavor (insofar as practicable and permitted under
the provisions of or governing the Book-Entry Interests or Global Debentures, as
the case may be), to take such measures regarding the requested consent, waiver
or other action in respect of such Book-Entry Interests or Global Debentures, as
the case may be, as shall be in accordance with any instructions set forth in
such request. The Book-Entry Depositary shall not itself exercise any discretion
in the granting of consents or waivers or the taking of any other action in
respect of the Book-Entry Interests or Global Debentures, as the case may be.

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

     Section 2.12. Reports.

     The Book-Entry Depositary shall immediately (and in no event later than 10

without



                                       9

deduction or withholding 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 the withholding or deduction is
then required by law. In the event that such withholding or deduction is
required to be made, the Book-Entry Depositary shall pay to the Depositary such
Additional Amounts that have been paid by the Issuer or the Guarantor to the
Book-Entry Depositary as will result in the payment to the Depositary of the
amount that would otherwise have been receivable by such party, as appropriate,
in the absence of such withholding or deduction; provided, that Additional
Amounts need only be paid to the Depositary to the extent that payments of
Additional Amounts from the Issuer or the Guarantor are required under Section
3.12 of the Indenture.

     At least 10 days prior to the first interest payment date, and at least 10
days prior to each succeeding interest payment date if there has been any change
with respect to the matters set forth in the below-mentioned Officers'
Certificate, the Issuer will furnish the Book-Entry Depositary with an Officers'
Certificate instructing the Book-Entry Depositary whether such payment of
principal of, premium, if any, or interest on such Book-Entry Interests shall be
made to the Depositary without deduction or withholding for or on account of any
Gross-Up Taxes. If any such deduction or withholding shall be required, prior to
such interest payment date the Issuer will furnish the Book-Entry Depositary
with an Officers' Certificate that specifies the amount required to be deducted
or withheld on such payment. The Issuer shall indemnify the Book-Entry
Depositary, its officers, directors and employees for, and hold it harmless
against, any loss, liability or expense reasonably incurred without negligence,
willful misconduct or bad faith on its part arising out of or in connection with
actions taken or omitted by it in reliance on any Officers' Certificate
furnished to it pursuant to this Section 2.13.

     Section 2.14. Changes Affecting Global Debentures.

     Upon any reclassification of the Global Debentures, or upon any
recapitalization, reorganization, merger or consolidation or sale of assets
affecting the Issuer or to which it is a party, or upon an exchange of the
Global Debentures pursuant to the Indenture, any securities that shall be
received by the Book-Entry Depositary in exchange for, in conversion of or in
respect of the Global Debentures shall be treated as new Global Debentures under
this Agreement and the Book-Entry Interests shall thenceforth represent
beneficial interests in such new Global Debentures so received.

such duties as are specifically set forth in this Agreement and no implied
covenants or obligations shall be read into this Agreement against the
Book-Entry Depositary.

conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon certificates or opinions furnished to the
Book-Entry Depositary and conforming to the requirements of this Agreement, but
in the case of any such certificates or opinions which by any provision hereof
are specifically required to be furnished to the Book-Entry Depositary, the
Book-Entry Depositary shall examine the same to determine whether or not they
conform to the requirements of this Agreement.

     (c) No provision of this Agreement shall be construed to relieve the
Book-Entry Depositary from liability for its own negligent action, its own
negligent failure to act or its own willful misconduct, except that:

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

          (ii) the Book-Entry Depositary shall not be liable with respect to any
     action taken or omitted to be taken by it in good faith in accordance with

     conducting any proceeding for any remedy available to the Book-Entry
     Depositary, or exercising any power conferred upon the Book-Entry
     Depositary, under this Agreement or the Indenture.

     (d) No provision of this Agreement shall require the Book-Entry Depositary
to spend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder, or in the exercise of any of its
rights or powers, if it shall have reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability
satisfactory to the Book-Entry Depositary has not been reasonably assured to it.

     (e) Whether or not therein expressly so provided, every provision of this
Agreement relating to the conduct or affecting the liability of or affording
protection to the Book-Entry Depositary shall be subject to the provisions of
this Section 3.01.

     (a) Within 90 days after the occurrence of any Event of Default of which a
Responsible Officer of the Book-Entry Depositary assigned to its corporate trust

waived.

the Book-Entry Depositary, in its discretion, may make further inquiry or
investigation into such facts or matters as it may see fit, and, if the
Book-Entry Depositary shall determine to make such further inquiry or
investigation, it shall be entitled upon reasonable prior request and during
normal business hours to examine the books, records and premises of the Issuer,
personally or by agent or attorney;

     (e) the Book-Entry Depositary may execute any of the trusts or powers

<PAGE>
 
     (f) the Book-Entry Depositary shall be under no obligation to expend or
risk its own funds or to exercise, at the request or direction of the

Indenture unless the Depositary shall have offered to the Book-Entry Depositary
security or indemnity satisfactory to the Book-Entry Depositary against the
costs, expenses and liabilities that might be incurred by it in compliance with
such request or direction;

     (g) whenever in the administration of its duties under this Agreement the

Book-Entry Depositary (unless other evidence be herein specifically prescribed)
may, in the absence of negligence or bad faith on its part, rely upon an
Officers' Certificate.

     Section 3.04. Not Responsible for Recitals or Issuance of Debentures.

     The recitals contained in the Indenture and in the Debentures, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Issuer and the Book-Entry Depositary assumes no responsibility for their
correctness. The Book-Entry Depositary makes no representations as to the
validity or sufficiency of this Agreement or of the Debentures. The Book-Entry
Depositary shall not be accountable for the use or application by the Issuer of
the proceeds with respect to the Debentures.

          (b) except as otherwise expressly provided herein, to reimburse the
     Book-Entry Depositary upon its request for all reasonable expenses,
     disbursements and advances incurred or made by the Book-Entry Depositary in
     accordance with any provision of this Agreement (including the reasonable
     compensation and the reasonable expenses and disbursements of its agents
     and counsel, which compensation, expenses and disbursements shall be set
     forth in sufficient written detail to the satisfaction of the Issuer),
     except any such expense, disbursement or advance as may be attributable to
     its or their negligence, willful misconduct or bad faith; and



                                       13
<PAGE>
 
          (c) to indemnify the Book-Entry Depositary for, and to hold it
     harmless against, any loss, liability or expense incurred without
     negligence, bad faith or willful misconduct on its part arising out of or
     in connection with the acceptance or administration of this Agreement and
     its duties hereunder, including the costs and expenses of defending itself
     against any claim of liability in connection with the exercise or

     provided by this Section 3.06(c) shall survive the satisfaction and
     discharge of this Agreement pursuant to Section 4.11 hereof.

     In case any claim shall be made or action brought against the Book-Entry
Depositary for any reason for which indemnity may be sought against the Issuer
in accordance with paragraph (c) above, the Book-Entry Depositary shall promptly
notify the Issuer in writing setting forth the particulars of such claim or
action and the Issuer may assume the defense thereof. In the event that the
Issuer elects to assume such defense and select such counsel, the Book-Entry
Depositary shall have the rights to employ its own counsel, but, in any such
case, the fees and expenses of such counsel shall be at the expense of the
Book-Entry Depositary, unless (i) the Issuer agreed in writing to pay such fees
and expenses or (ii) the named parties to any such action (including any
impleaded parties) include both the Book-Entry Depositary and the Issuer and the
Book-Entry Depositary shall have been advised by its counsel that a conflict of
interest between the Book-Entry Depositary and the Issuer may arise (and
Issuer's counsel shall have concurred with such advise) and for this reason it
is not desirable for the Issuer's counsel to represent both the Book-Entry
Depositary and the Issuer (it being understood, however, that the Issuer shall
not, in connection with any one such action or separate but substantially
similar or related actions in the same jurisdiction arising out of the same
general allegations or circumstances, be liable for reasonable fees and expenses
of more than one separate firm of attorneys for the Book-Entry Depositary (plus
any local counsel retained by the Book-Entry Depositary in their reasonable
judgement), which firm shall be designated in writing by the Book-Entry
Depositary). The Book-Entry Depositary agrees to give all assistance reasonably
required in connection with the conduct of any such claim or action.

     Section 3.07. Book-Entry Depositary Required; Eligibility.

     At all times when there is a Book-Entry Depositary hereunder, such
Book-Entry Depositary shall be a corporation organized and doing business under
the laws of the United States of America, any state thereof or the District of
Columbia, having, together with its parents, a combined capital and surplus of
at least $50,000,000, subject to supervision or examination by Federal, state or
District of Columbia authority and willing to act on reasonable terms. Such
corporation shall have its principal place of business in the Borough of
Manhattan, The City of New York, if there be such a corporation in such location
willing to act upon reasonable and customary terms and conditions. If such
corporation, or its parent, publishes reports of condition at least annually,
pursuant to law or to the requirements of the aforesaid supervising or examining
authority, then for the purposes of this Section 3.07, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. The
Book-Entry Depositary



                                       14
<PAGE>
 
hereunder shall at all times be the Trustee under the Indenture, subject to
receipt of an Opinion of Counsel that the same Person is precluded by law from
acting in such capacities. If at any time the Book-Entry Depositary shall cease
to be eligible in accordance with the provisions of this Section 3.07, it shall
resign immediately in the manner and with the effect hereinafter specified in
this Article. 

     Section 3.08. Resignation and Removal; Appointment of Successor.

     (a) No resignation or removal of the Book-Entry Depositary and no
appointment of a successor Book-Entry Depositary pursuant to this Article shall
become effective until (i) the acceptance of appointment by the successor
Book-Entry Depositary in accordance with the applicable requirements of Section
3.09 hereof or (ii) the issuance of Definitive Registered Debentures for all
Global Debentures in accordance with Section 2.05 hereof and the Indenture.

     (b) The Book-Entry Depositary may at any time resign as Book-Entry
Depositary with respect to the Global Debentures by giving written notice
thereof to the Issuer and the Depositary, in accordance with Section 4.01 and
Section 4.02 hereof, 60 days prior to the effective date of such resignation.
The Book-Entry Depositary may be removed at any time upon 90 days' notice by the
filing with it of an instrument in writing signed on behalf of the Issuer and
specifying such removal and the date when it is intended to become effective. If
the instrument of acceptance by a successor Book-Entry Depositary required by
Section 3.09 hereof shall not have been delivered to the Book-Entry Depositary
within 30 days after the giving of such notice of resignation or removal, the
resigning Book-Entry Depositary may petition any court of competent jurisdiction
for the appointment of a successor Book-Entry Depositary.

     (c) If at any time:

          (i) the Book-Entry Depositary shall cease to be eligible under Section
     3.07 hereof, or shall cease to be eligible as Trustee under the Indenture,
     and shall fail to resign after written request therefor by the Issuer or by
     the Depositary, or

          (ii) the Book-Entry Depositary shall become incapable of acting with
     respect to the Book-Entry Interests or shall be adjudged a bankrupt or
     insolvent, or a receiver or liquidator of the Book-Entry Depositary or of
     its property shall be appointed or any public officer shall take charge or
     control of the Book-Entry Depositary or of its property or affairs for the
     purpose of rehabilitation, conservation or liquidation.

then, in any such case, (i) the Issuer, by Board Resolution, may remove the
Book-Entry Depositary and appoint a successor Book-Entry Depositary, and (ii) if
the Issuer shall fail to remove such Book-Entry Depositary and appoint a
successor Book-Entry Depositary within 30 days of any such event, then the
Depositary may, on behalf of itself and all others similarly situated, petition
any court of competent jurisdiction for the removal of the Book-Entry Depositary
or Book-Entry Depositaries and the appointment of a



                                       15
<PAGE>
 
successor Book-Entry Depositary, unless Definitive Registered Debentures have
been issued in accordance with the Indenture.

     (d) If the Book-Entry Depositary shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Book-Entry
Depositary for any cause, the Issuer, by Board Resolution, shall promptly
appoint a successor Book-Entry Depositary (other than the Issuer) and shall
comply with the applicable requirements of Section 3.09 hereof. If no successor
Book-Entry Depositary with respect to the Global Debentures shall have been so
appointed by the Issuer and accepted appointment in the manner required by
Section 3.09 within 120 days of any such resignation, removal, incapacity or
vacancy, then the Depositary may request that Definitive Registered Debentures
in such names and denominations as the Depositary shall instruct in writing with
respect to such Global Debentures be issued. The Book-Entry Depositary will
thereupon surrender such Global Debentures to the Trustee for cancellation and
the Trustee shall distribute such Definitive Registered Debentures in accordance
with the instructions of the Depositary.

     (e) The Issuer shall give, or shall cause such successor Book-Entry
Depositary to give, notice of each resignation and each removal of a Book-Entry
Depositary and each appointment of a successor Book-Entry Depositary to the
Depositary in accordance with Section 4.02 hereof. Each notice shall include the
name of the successor Book-Entry Depositary and the address of its Corporate
Trust Office.

     Section 3.09. Acceptance of Appointment by Successor.

     (a) In case of the appointment hereunder of a successor Book-Entry
Depositary, every such successor Book-Entry Depositary so appointed shall
execute, acknowledge and deliver to the Issuer and to the retiring Book-Entry
Depositary an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Book-Entry Depositary shall become
effective and such successor Book-Entry Depositary, without any further act,
deed or conveyance, shall become vested with all the rights, powers, agencies
and duties of the retiring Book-Entry Depositary, with like effect as if
originally named as Book-Entry Depositary hereunder; but, on the request of the
Issuer or the successor Book-Entry Depositary, such retiring Book-Entry
Depositary shall (i) execute and deliver an instrument transferring to such
successor Book-Entry Depositary all the rights and powers of the retiring
Book-Entry Depositary and (ii) duly assign, transfer and deliver to such
successor Book-Entry Depositary all property and money held by such retiring
Book-Entry Depositary hereunder. Any retiring Book-Entry Depositary shall,
nonetheless, retain a prior claim upon all property or funds held or collected
by such Book-Entry Depositary to secure any amounts then due it pursuant to
Section 3.06 hereof except to the extent that such prior claim and security
would breach or constitute a default under the Indenture or Debentures.

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



                                       16

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

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

     Section 3.10. Merger, Conversion, Consolidation or Succession to Business.

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

     Section 3.11. Letter of Representations.

     The Book-Entry Depositary agrees to enter into and comply with all of the
provisions set forth in the Letters of Representations so long as DTC is the
holder of the Book-Entry Interests.

     Section 4.02. Notice to the Depositary; Waiver.

such notice shall be sufficiently given (unless otherwise herein expressly

mailed, first-class postage prepaid, to the Depositary at the address notified
to the Book-Entry Depositary, in each case not later than the latest date, and
not earlier than the earliest date, prescribed for the giving of such notice.
Where this Agreement provides for notice in any manner, such notice may be
waived in writing by the Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice.
Waivers of notice by the Depositary shall be filed with the Book-Entry
Depositary, but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver.

     In case by reason of the suspension of regular mail service or by reason of
any other cause it shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Book-Entry Depositary
shall constitute a sufficient notification for every purpose hereunder.

     Section 4.03. Effect of Headings and Table of Contents.

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

     Section 4.04. Successors and Assign.

     Nothing in this Agreement, the Debentures or the Indenture, express or
implied, shall give to any Person, other than the parties hereto and their
successors hereunder, any benefits or any legal or equitable right, remedy or
claim under this Agreement; provided, that the Depositary and the beneficial
owners of Interests shall be intended third-party beneficiaries of this
Agreement. The Depositary and beneficial owners from time to time of Interests
in the Book-Entry Interests shall be parties to this Agreement and shall be
bound by all of the terms and conditions hereof and of the Indenture and the
Debentures, by their acceptance of delivery of the Interests or beneficial
interests therein.

     Section 4.07. GOVERNING LAW.

     THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE
LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES

     Section 4.08. Jurisdiction.

     (a) The Issuer agrees that any legal suit, action or proceeding against the
Issuer brought by the Book-Entry Depositary arising out of or based upon this
Agreement may be instituted in any state or Federal court in the Borough of
Manhattan, The City of New York, and waives any objection which it may now or
hereafter have to the laying of venue of any such proceeding and, until the
satisfaction and discharge of this Agreement pursuant to Section 4.11 hereof,
irrevocably submits to the nonexclusive jurisdiction of such courts in any suit,
action or proceeding.

     (b) The Issuer has appointed CT Corporation System at 1633 Broadway, New

based upon this Agreement which may be instituted in the Supreme Court of New
York, New York County of the United States District Court for the Southern
District of New York by DTC or the Book-Entry Depositary, and expressly accepts
the nonexclusive jurisdiction of any such court in respect of any such action.
Such appointment shall be irrevocable. Service of process upon the Authorized
Agent shall be deemed, in every respect, effective service of process upon the
Issuer. Notwithstanding the foregoing, any action based on this Agreement may be
instituted by the Book-Entry Depositary in any competent court in England or the
Cayman Islands. 

     (c) To the extent that the Issuer may in any jurisdiction claim for itself
or its assets immunity (to the extent such immunity may now or hereafter exist,
whether on the grounds of sovereign immunity or otherwise) from suit, execution,
attachment (whether in aid of execution, before judgment or otherwise) or other
legal process (whether through service or notice or otherwise), and to the
extent that in any such



                                       19

jurisdiction there may be attributed to itself or its assets such immunity
(whether or not claimed), the Issuer irrevocably agrees with respect to any
matter arising under this Deposit Agreement for the benefit of the Registered

irrevocably waives, such immunity to the full extent permitted by the laws of
such jurisdiction.

one and the same instrument.

     Section 4.10. Inspection of Agreement.

     A copy of this Agreement shall be available at all reasonable times during
normal business hours at the Corporate Trust Office of the Book-Entry Depositary
for inspection by the Depositary.

     This Agreement upon Issuer Order shall cease to be of further effect, and
the Book-Entry Depositary, at the expense of the Issuer shall execute proper
instruments acknowledging satisfaction and discharge of this Agreement, when (i)
either (a) the Indenture has been satisfied and discharged pursuant to the
provisions thereof or (b) Definitive Registered Debentures have been issued and
the Global Debentures have been canceled in accordance with the provisions of

     Exchange Act, the Investment Company Act of 1940, as amended, the Trust
     Indenture Act or any other applicable securities laws;

          (e) to modify this Agreement in connection with an amendment to the

     counsel acceptable to the Issuer, is not materially adverse to the
     Depositary or the beneficial owners of Interests.

     Except as set forth in this Section 4.12, no amendment which materially
adversely affects the Depositary or beneficial owners of Interests may be made
to this Agreement without the consent of the Depositary or such beneficial

Yorkshire Capital Trust I
1 Riverside Plaza
Columbus, Ohio 43215

          Re:  Yorkshire Capital Trust I
               -------------------------

Ladies and Gentlemen:

          We have acted as special Delaware counsel for AEP Resources, Inc., an
Ohio corporation (the "Company"), and Yorkshire Capital Trust I, a Delaware
business trust (the "Trust"), in connection with the matters set forth herein.
At your request, this opinion is being furnished to you.

          For purposes of giving the opinions hereinafter set forth, our
examination of documents has been limited to the examination of originals or
copies of the following:

          (a) The Certificate of Trust of the Trust, dated February 4, 1998 (the
"Certificate"), as filed in the office of the Secretary of State of the State of
Delaware (the "Secretary of State") on February 4, 1998;

          (b) The Trust Agreement of the Trust, dated as of February 4, 1998,
among the Company, as depositor, and the trustees of the Trust named therein;

          (c) Amendment No. 1 to the Registration Statement (the "Registration
Statement") on Form S-1, including a preliminary prospectus (the "Prospectus"),
relating to the __% Trust Securities of the Trust representing preferred
undivided beneficial interests in the assets of the Trust (each, a "Trust
Security" and collectively, the "Trust Securities"), as proposed to be filed by
the Company and the Trust with the Securities and Exchange Commission on or
about May 1, 1998;

          (d) A form of Amended and Restated Trust Agreement of the Trust, to be
entered into among the Company, as depositor, the trustees of the Trust named
therein, Yorkshire Power Group Limited, as control party, and the holders, from
time to time, of undivided beneficial interests in the assets of the Trust
(including Exhibits A and C thereto) (the "Trust Agreement"), attached as an
exhibit to the Registration Statement; and
<PAGE>
 
          (e) A Certificate of Good Standing for the Trust, dated May 1, 1998,
obtained from the Secretary of State.

          Initially capitalized terms used herein and not otherwise defined are
used as defined in the Trust Agreement.

          For purposes of this opinion, we have not reviewed any documents other
than the documents listed in paragraphs (a) through (e) above.  In particular,
we have not reviewed any document (other than the documents listed in paragraphs
(a) through (e) above) that is referred to in or incorporated by reference into
the documents reviewed by us.  We have assumed that there exists no provision in
any document that we have not reviewed that is inconsistent with the opinions
stated herein.  We have conducted no independent factual investigation of our
own but rather have relied solely upon the foregoing documents, the statements
and information set forth therein and the additional matters recited or assumed
herein, all of which we have assumed to be true, complete and accurate in all
material respects.

          With respect to all documents examined by us, we have assumed (i) the
authenticity of all documents submitted to us as authentic originals, (ii) the
conformity with the originals of all documents submitted to us as copies or
forms, and (iii) the genuineness of all signatures.

          For purposes of this opinion, we have assumed (i) that the Trust
Agreement and the Certificate are in full force and effect and have not been
amended, (ii) except to the extent provided in paragraph 1 below, the due
creation or due organization or due formation, as the case may be, and valid
existence in good standing of each party to the documents examined by us under
the laws of the jurisdiction governing its creation, organization or formation,
(iii) the legal capacity of natural persons who are parties to the documents
examined by us, (iv) that each of the parties to the documents examined by us
has the power and authority to execute and deliver, and to perform its
obligations under, such documents, (v) the due authorization, execution and
delivery by all parties thereto of all documents examined by us, (vi) the
receipt by each Person to whom a Trust Security is to be issued by the Trust
(collectively, the "Trust Security Holders") of a Trust Securities Certificate
for such Trust Security and the payment for the Trust Security acquired by it,
in accordance with the Trust Agreement and the Registration Statement, and (vii)
that the Trust Securities are issued and sold to the Trust Security Holders in
accordance with the Trust Agreement and the Registration Statement.  We have not
participated in the preparation of the Registration Statement and assume no
responsibility for its contents.

          This opinion is limited to the laws of the State of Delaware
(excluding the securities laws of the State of Delaware), and we have not
considered and express no opinion on the laws of any other jurisdiction,
including federal laws and rules and regulations relating thereto. Our opinions
are rendered only with respect to Delaware laws and rules, regulations and
orders thereunder that are currently in effect.
<PAGE>
 
          Based upon the foregoing, and upon our examination of such questions
of law and statutes of the State of Delaware as we have considered necessary or
appropriate, and subject to the assumptions, qualifications, limitations and
exceptions set forth herein, we are of the opinion that:

          1.   The Trust has been duly created and is validly existing in good
standing as a business trust under the Delaware Business Trust Act.

          2.   The Trust Securities will represent valid and, subject to the
qualifications set forth in paragraph 3 below, fully paid and nonassessable
undivided beneficial interests in the assets of the Trust.

          3.   The Trust Security Holders, as beneficial owners of the Trust,
will be entitled to the same limitation of personal liability extended to
stockholders of private corporations for profit organized under the General
Corporation Law of the State of Delaware.  We note that the Trust Security
Holders may be obligated to make payments as set forth in the Trust Agreement.

          We consent to the filing of this opinion with the Securities and
Exchange Commission as an exhibit to the Registration Statement.  In addition,
we hereby consent to the use of our name under the heading "Legal Opinions" in
the Prospectus.  In giving the foregoing consents, we do not thereby admit that
we come within the category of Persons whose consent is required under Section 7
of the Securities Act of 1933, as amended, or the rules and regulations of the
Securities and Exchange Commission thereunder.  Except as stated above, without
our prior written consent, this opinion may not be furnished or quoted to, or
relied upon by, any other Person for any purpose.

                         Very truly yours,

                         /s/ RICHARDS, LAYTON & FINGER, P.A.

     Re:  Registration Statement on Form S-1
          ----------------------------------

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
<PAGE>
 
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

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

opinion expressed in clause (ii) immediately above with respect to the validity
of the Junior Subordinated Debentures, we have relied upon the opinion address

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"). 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 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").



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 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) and will be legal, valid, binding
     and enforceable against all relevant parties in accordance with their
     respective terms under the laws of the State of New York and all other
     relevant laws (other than the laws of the Cayman Islands);

(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 solely for the benefit of the addressee but may be relied upon
by the addressee's legal advisors (in that capacity only).  It may not be relied
upon by (nor may it be disclosed to) any other person, without the prior written
consent of this firm.  However, we do 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.
