Transmittal, have such stockholder's signature thereon guaranteed if required by
Instruction 1 to the Letter of Transmittal, mail or deliver the Letter of
Transmittal or such facsimile, or, in the case of a book-entry transfer effected
pursuant to the procedure set forth in Section 2, an Agent's Message (as defined
herein), and any other required documents, to the Depositary (as defined herein)
and either deliver the certificates for such Shares to the Depositary along with
the Letter of Transmittal or facsimile or deliver such Shares pursuant to the
procedure for book-entry transfer set forth in Section 2 of this Offer to
Purchase or (ii) request such stockholder's broker, dealer, commercial bank,
trust company or other nominee to effect the transaction for such stockholder. A
stockholder having Shares registered in the name of a broker, dealer, commercial
bank, trust company or other nominee must contact such broker, dealer,
commercial bank, trust company or other nominee if such stockholder desires to
tender such Shares.

     Any stockholder who desires to tender Shares and whose certificates
representing such Shares are not immediately available or who cannot comply in a
timely manner with the procedure for book-entry transfer, or who cannot deliver
all required documents to the Depositary prior to the expiration of the Offer,
may tender such Shares by following the procedure for guaranteed delivery set
forth in Section 2 of this Offer to Purchase.

To the holders of Common Stock of Easco, Inc.

                                  INTRODUCTION

     E Acqco Inc., a Delaware corporation (the "Purchaser") and an indirect
wholly owned subsidiary of Caradon Inc., a Delaware corporation ("Parent"),
hereby offers to purchase all outstanding shares of Common Stock, $.01 par value
(the "Shares"), of Easco, Inc., a Delaware corporation (the "Company"), at a
purchase price of $15.20 per Share, net to the seller in cash, without interest,
all upon the terms and subject to the conditions set forth in this Offer to
Purchase and in the related Letter of Transmittal (which, together with any
amendments or supplements thereto, constitute the "Offer").

     Tendering stockholders whose Shares are registered in their own name and
who tender Shares directly to the Depositary (as defined below) will not be
obligated to pay brokerage fees or commissions to the Purchaser or the
Depositary or, except as set forth in Instruction 6 of the Letter of
Transmittal, transfer taxes on the purchase of Shares pursuant to the Offer.
Stockholders who hold their Shares through a bank or broker should check with
such institution as to whether they charge any service fees. The Purchaser will
pay the fees and expenses of ChaseMellon Shareholder Services, L.L.C., which is
acting as the Depositary (the "Depositary"), and D. F. King & Co., Inc., which
is acting as Information Agent (the "Information Agent"), in connection with the
Offer. See Section 17.

     THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY APPROVED THE OFFER,
THE MERGER AND THE MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY,
HAS UNANIMOUSLY DETERMINED THAT THE TERMS OF EACH OF THE OFFER AND THE MERGER
ARE FAIR TO AND IN THE BEST INTERESTS OF THE COMPANY'S STOCKHOLDERS AND
UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS OF THE COMPANY TENDER THEIR SHARES
PURSUANT TO THE OFFER.

     Wasserstein Perella & Co., Inc. ("Wasserstein Perella"), the Company's
financial advisor, has delivered to the Company's Board of Directors its written
opinion that the $15.20 per Share cash consideration to be received by the
Company's stockholders in the Offer and the Merger is fair to such stockholders
(other than Parent or the Purchaser and their respective subsidiaries and
affiliates) from a financial point of view. A copy of such opinion is contained
in the Company's Solicitation/Recommendation Statement on Schedule 14D-9 which
is being distributed to the Company's stockholders.

     THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THERE HAVING BEEN
VALIDLY TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER, WHICH
WILL BE 12:00 MIDNIGHT, NEW YORK CITY TIME, ON MONDAY, AUGUST 30, 1999, OR SUCH
OTHER TIME TO WHICH THE PURCHASER EXTENDS THE OFFER, SUCH NUMBER OF SHARES THAT
WOULD CONSTITUTE A MAJORITY OF THE OUTSTANDING SHARES AT THE DATE OF THE
EXPIRATION OF THE OFFER (ASSUMING THE EXERCISE OF ALL OPTIONS TO PURCHASE SHARES
OUTSTANDING AT THE EXPIRATION DATE OF THE OFFER) (THE "MINIMUM CONDITION"). THE
OFFER IS ALSO CONDITIONED UPON THE WAITING PERIOD UNDER THE HART-SCOTT-RODINO
ANTITRUST IMPROVEMENTS ACT OF 1976, AS AMENDED (THE "HSR ACT"), APPLICABLE TO
THE PURCHASE OF SHARES PURSUANT TO THE OFFER HAVING EXPIRED OR BEEN TERMINATED.
THE OFFER IS ALSO SUBJECT TO OTHER TERMS AND CONDITIONS. SEE SECTION 15.

     The Offer is being made pursuant to the Agreement and Plan of Merger, dated
as of July 28, 1999 (the "Merger Agreement"), among Parent, the Purchaser and
the Company. The Merger Agreement provides that, among other things, after the
purchase of Shares pursuant to the Offer and the satisfaction of the other
conditions set forth in the Merger Agreement and in accordance with the relevant
provisions of the Delaware General Corporation Law, as amended (the "Delaware
Law"), the Purchaser will be merged with and into the Company (the "Merger"). If
the Purchaser acquires at least 90% of the outstanding Shares pursuant to the
Offer, the Purchaser would be able to effect the Merger pursuant to the
"short-form" merger provisions of Section 253 of the Delaware Law, without prior
notice to, or any action by, any stockholder of the Company. See Section 12.
Following consummation of the Merger, the Company will continue as the surviving
corporation (the "Surviving Corporation") and will be an indirect wholly owned
subsidiary of Parent. At the effective time of the Merger (the "Effective
Time"), each Share that is issued and outstanding (other than Shares held (i) in
the treasury of the Company or by Parent or any direct or indirect wholly owned
subsidiary of Parent immediately before the Effective Time, or (ii) by
stockholders, if any, who are entitled to and who properly exercise appraisal
rights under the Delaware Law) will be converted into the right to receive the
Offer Price. The "Offer Price" per Share is $15.20 (or any higher price that may
be paid for each Share pursuant to

                                        1
<PAGE>   4

the Offer) net to the seller in cash, without interest thereon. See Section 5
for a description of certain tax consequences of the Offer and the Merger.

     The Merger Agreement provides that, promptly after the Purchaser acquires
any Shares pursuant to the Offer, and from time to time thereafter as the
Purchaser acquires Shares, Parent will be entitled to designate such number of
directors, rounded up to the next whole number, on the Company's Board of
Directors as is equal to the product of (i) the total number of directors on the
Board of Directors (giving effect to the directors designated by Parent)
multiplied by (ii) the percentage of outstanding Shares then beneficially owned
by the Purchaser. However, until the Effective Time, the Board of Directors of
the Company will continue to have at least one director who was a director on
the date of the Merger Agreement and who is neither an officer of the Company
nor a designee, stockholder, affiliate or associate of Parent (each, an
"Independent Director"). If no Independent Directors remain on the Company's
Board of Directors, the other directors will designate one person to fill such
vacancy who meets the eligibility requirements for Independent Directors. The
Company has agreed either to increase (but not above 10 persons) the size of the
Board of Directors of the Company or to obtain the resignation of such number of
directors as is necessary to enable the Purchaser's designees to be elected or
appointed to the Board.

     The Company has advised the Purchaser that as of the date of the Merger
Agreement, there were (i) 9,673,224 Shares issued and outstanding (excluding
Shares held by the Company or any direct or indirect wholly owned subsidiary)
and (ii) 836,475 Shares reserved for issuance under outstanding stock options.
As of the date hereof, neither the Purchaser nor Parent beneficially owns any
Shares, except as may be attributable to it by reason of entering into the
Stockholder Agreements as discussed below. If at least a majority of the Shares
are validly tendered and not withdrawn in the Offer (assuming the exercise of
all options to purchase Shares outstanding at the expiration date of the Offer),
the Minimum Condition will be satisfied and, upon the purchase of such Shares,
the Purchaser will control a majority of the outstanding Shares. Accordingly,
the Purchaser would have sufficient voting power to approve the Merger without
the affirmative vote of any other stockholder. See Section 15. No Shares owned
by the Company or any direct or indirect wholly owned subsidiary will be
tendered in the Offer.

     The Purchaser and Parent have entered into Stockholder Agreements (the
"Stockholder Agreements"), each dated as of July 28, 1999, with American
Industrial Partners Capital Fund, L.P. ("AIP") and each of the Company's
directors and executive officers who own Shares. Those stockholders (the
"Stockholders") that entered into the Stockholder Agreements collectively own
approximately 46% of the outstanding Shares as of the date of the Merger
Agreement (excluding Shares held by the Company or any direct or indirect wholly
owned subsidiary). Such Stockholders would collectively own approximately 49% of
the outstanding Shares assuming that all outstanding stock options were
exercised. Under the Stockholder Agreements, each Stockholder agreed, among
other things, to validly tender in the Offer the Shares beneficially owned by it
or him, as well as any Shares subsequently acquired by it or him. The
Stockholder Agreements are more fully described in Section 13. Pursuant to its
Stockholder Agreement, AIP (owning approximately 44% of the outstanding Shares)
has also agreed to vote its Shares in favor of the Merger, the adoption by the
Company of the Merger Agreement and the approval of the terms thereof and each
of the other transactions contemplated by the Merger Agreement, and agreed to
vote against (i) any Takeover Proposal (as defined in Section 13) by any third
party, (ii) the following actions (other than the Merger and the transactions
contemplated by the Merger Agreement): (a) any extraordinary corporation
transaction, such as a merger, consolidation or other business combination
involving the Company or its subsidiaries; (b) a sale, lease or transfer of a
material amount of assets of the Company or its subsidiaries or a
reorganization, recapitalization, dissolution or liquidation of the Company or
its subsidiaries; (c)(1) any change in the majority of the board of directors of
the Company; (2) any change in the present capitalization of the Company or any
amendment of the Company's Certificate of Incorporation; (3) any other change in
the Company's corporate structure or business; or (4) any other action; which,
in the case of the matters referred to in clauses (1), (2) or (3) above, is
intended, or could reasonably be expected, to impede, interfere with, delay,
postpone, discourage or materially and adversely affect the contemplated
economic benefits to Parent of the Merger or the Offer. Pursuant to its
Stockholder Agreement, AIP has also granted to Parent an irrevocable proxy
pursuant to which it irrevocably appointed representatives of Parent and the
Purchaser as its proxies and attorneys-in-fact to vote its Shares in the
foregoing manner at any time until the earlier to occur of the valid termination
of the Merger Agreement or the Effective Time.

     The Merger Agreement and the Stockholder Agreements are more fully
described in Section 13. Certain federal income tax consequences of the sale of
Shares pursuant to the Offer and the exchange of Shares for the Offer Price
pursuant to the Merger are described in Section 5.

     THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION THAT SHOULD BE READ BEFORE ANY DECISION IS MADE WITH
RESPECT TO THE OFFER.

1. TERMS OF THE OFFER.

     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of any extension or
amendment), the Purchaser will accept for payment and pay for all Shares validly
tendered and not withdrawn prior to the Expiration Date in accordance with
Section 4. The term "Expiration Date" means 12:00 midnight, New York City time,
on Monday, August 30, 1999, unless the Purchaser extends the period of time for
which the Offer is open, in which event the term "Expiration Date" shall mean
the latest time and date at which the Offer, as so extended by the Purchaser,
shall expire.

     If the Purchaser decides, in its sole discretion, to increase the
consideration offered in the Offer to holders of Shares and if, at the time that
notice of such increase is first published, sent or given to holders of Shares
in the manner specified below, the Offer is scheduled to expire at any time
earlier than the expiration of a period ending on the tenth business day from,
and including, the date that such notice is first so published, sent or given,
then the Offer will be extended until the expiration of such period of 10
business days. For purposes of the Offer, a "business day" means any day other
than a Saturday, Sunday or a federal holiday and consists of the time period
from 12:01 a.m. through 12:00 midnight, New York City time.

     THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THE SATISFACTION OF THE
MINIMUM CONDITION. SEE SECTION 15. If the conditions to the Offer are not
satisfied prior to the Expiration Date, the Purchaser reserves the right (but
shall not be obligated), subject to the terms of the Merger Agreement, to (i)
decline to purchase any of the Shares tendered and terminate the Offer, (ii)
waive any of the conditions to the Offer, to the extent permitted by applicable
law, and, subject to complying with applicable rules and regulations of the SEC,
purchase all Shares validly tendered or (iii) extend the Offer and, subject to
the right of stockholders to withdraw Shares until the Expiration Date, retain
the Shares tendered during the period or periods for which the Offer is
extended.

     Under the terms of the Merger Agreement, the Purchaser may not (except as
described in the next sentence), without the consent of the Company, reduce the
number of Shares subject to the Offer, amend or waive the Minimum Condition,
reduce the Offer Price or change the form of consideration payable in the Offer,
or amend any other condition of the Offer in any manner adverse to the holders
of Shares. Notwithstanding the foregoing, the Purchaser may, without the consent
of the Company, extend the Offer (i) if at the then-scheduled Expiration Date of
the Offer, all of the conditions shall not have been satisfied or waived, until
such time as such conditions are satisfied or waived, or (ii) on one or more
occasions for an aggregate period of not more than ten business days beyond the
then-scheduled Expiration Date if, as of such Expiration Date, sufficient Shares
have not been tendered in order for the Merger to be effected pursuant to a
"short-form" merger pursuant to Section 253 of the Delaware Law without prior
notice to, or any action by, any stockholders of the Company (which would
require that the Purchaser has acquired at least 90% of the outstanding Shares).
See Sections 13 and 15.

     Subject to the limitations set forth in this Offer to Purchase and the
Merger Agreement, the Purchaser reserves the right (but will not be obligated),
at any time or from time to time in its sole discretion, to extend the period
during which the Offer is open by giving oral or written notice of such
extension to the Depositary and by making a public announcement of such
extension. There can be no assurance that the Purchaser will exercise its right
to extend the Offer.

     Subject to the applicable rules and regulations of the Securities and
Exchange Commission (the "SEC") and subject to the limitations set forth in the
Merger Agreement, the Purchaser expressly reserves the right, at any time and
from time to time, in its sole discretion, (i) to delay payment for any Shares
regardless of whether such Shares were already accepted for payment, or to
terminate the Offer and not to accept for payment or pay for any Shares not
already accepted for payment or paid for, upon the occurrence of any of the
conditions set forth in Section 15, by giving oral or written notice of such
delay or termination to the

                                        3
<PAGE>   6

Depositary, and (ii) at any time or from time to time, to amend the Offer in any
respect. The Purchaser's right to delay payment for any Shares or not to pay for
any Shares theretofore accepted for payment is subject to the applicable rules
and regulations of the SEC, including Rule 14e-1(c) under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), relating to the
Purchaser's obligation to pay for or return tendered Shares promptly after the
termination or withdrawal of the Offer.

     Any extension of the period during which the Offer is open, delay in
acceptance for payment or payment, termination or amendment of the Offer will be
followed, as promptly as practicable, by a public announcement thereof, such
announcement in the case of an extension to be issued not later than 9:00 a.m.,
New York City time, on the next business day after the previously scheduled
Expiration Date in accordance with the public announcement requirements of Rules
14d-4(c) and 14e-1(d) under the Exchange Act. Without limiting the obligation of
the Purchaser under such rule or the manner in which the Purchaser may choose to
make any public announcement, the Purchaser currently intends to make
announcements by issuing a press release to the Dow Jones News Service and
making any appropriate filing with the SEC.

     If, subject to the terms of the Merger Agreement, the Purchaser makes a
material change in the terms of the Offer or the information concerning the
Offer, or if it waives a material condition of the Offer (including, with the
consent of the Company, a waiver of the Minimum Condition), the Purchaser will
disseminate additional tender offer materials and extend the Offer if and to the
extent required by Rules 14d-4(c), 14d-6(d) and 14e-1 under the Exchange Act or
otherwise. The minimum period during which a tender offer must remain open
following material changes in the terms of the offer or the information
concerning the offer, other than a change in price or a change in percentage of
securities sought, will depend upon the facts and circumstances, including the
relative materiality of the terms or information changes. With respect to a
change in price or a change in percentage of securities sought, a minimum 10
business day period may be required to allow for adequate dissemination to
stockholders and investor response.

     The Company has provided the Purchaser with the Company's list of
stockholders and security position listings for the purpose of disseminating the
Offer to holders of Shares. This Offer to Purchase and the related Letter of
Transmittal will be mailed to record holders of Shares whose names appear on the
Company's stockholder list and will be furnished to brokers, dealers, commercial
banks, trust companies and similar persons whose names, or the names of whose
nominees, appear on the stockholder list or, if applicable, who are listed as
participants in a clearing agency's security position listing for subsequent
transmittal to beneficial owners of Shares.

2. PROCEDURE FOR TENDERING SHARES.

     Valid Tender. For a stockholder validly to tender Shares pursuant to the
Offer, either (i) a properly completed and duly executed Letter of Transmittal
(or facsimile thereof), together with any required signature guarantees or, in
the case of a book-entry transfer, an Agent's Message (as defined below), and
any other documents required by the Letter of Transmittal, must be received by
the Depositary at one of its addresses set forth on the back cover of this Offer
to Purchase prior to the Expiration Date, and either (a) certificates for
tendered Shares must be received by the Depositary at one of such addresses
prior to the Expiration Date or (b) such Shares must be delivered pursuant to
the procedure for book-entry transfer set forth below and a Book-Entry
Confirmation (as defined below) received by the Depositary prior to the
Expiration Date, or (ii) the tendering stockholder must comply with the
guaranteed delivery procedures set forth below and in the Letter of Transmittal.

     Book-Entry Transfer. The Depositary will establish an account with respect
to the Shares at The Depository Trust Company (the "Book-Entry Transfer
Facility") for purposes of the Offer within two business days after the date of
this Offer to Purchase. Any financial institution that is a participant in the
Book-Entry Transfer Facility's system may make book-entry delivery of Shares by
causing the Book-Entry Transfer Facility to transfer such Shares into the
Depositary's account in accordance with the Book-Entry Transfer Facility's
procedures for such transfer. However, although delivery of Shares may be
effected through book-entry transfer into the Depositary's account at the
Book-Entry Transfer Facility, the Letter of Transmittal (or facsimile thereof),
properly completed and duly executed, with any required signature guarantees, or
an Agent's Message, and any other required documents, must, in any case, be
transmitted to, and received by, the Depositary at one of its addresses set
forth on the back cover of this Offer to Purchase
                                        4
<PAGE>   7

prior to the Expiration Date, or the tendering stockholder must comply with the
guaranteed delivery procedure described below. The confirmation of a book-entry
transfer of Shares into the Depositary's account at the Book-Entry Transfer
Facility as described above is referred to herein as a "Book-Entry
Confirmation."

     DELIVERY OF DOCUMENTS TO THE BOOK-ENTRY TRANSFER FACILITY IN ACCORDANCE
WITH THE BOOK-ENTRY TRANSFER FACILITY'S PROCEDURES DOES NOT CONSTITUTE DELIVERY
TO THE DEPOSITARY.

     The term "Agent's Message" means a message transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that the Book-Entry Transfer Facility has
received an express acknowledgment from the participant in the Book-Entry
Transfer Facility tendering the Shares that such participant has received and
agrees to be bound by the terms of the Letter of Transmittal and that the
Purchaser may enforce such agreement against the participant.

     THE METHOD OF DELIVERY OF SHARES, THE LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE BOOK-ENTRY TRANSFER FACILITY,
IS AT THE ELECTION AND RISK OF THE TENDERING STOCKHOLDER. SHARES WILL BE DEEMED
DELIVERED ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY. IF DELIVERY IS BY MAIL,
REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED.
IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.

     Signature Guarantees. No signature guarantee is required on the Letter of
Transmittal if (i) the Letter of Transmittal is signed by the registered holder
of Shares (which, for purposes of this Section, includes any participant in the
Book-Entry Transfer Facility's system whose name appears on a security position
listing as the owner of the Shares) tendered therewith and such registered
holder has not completed either the box entitled "Special Delivery Instructions"
or the box entitled "Special Payment Instructions" on the Letter of Transmittal
or (ii) such Shares are tendered for the account of a firm that is a participant
in the Security Transfer Agents Medallion Program, the New York Stock Exchange
Medallion Signature Guarantee Program or the Stock Exchange Medallion Program
(each, an "Eligible Institution"). In all other cases, all signatures on the
Letter of Transmittal must be guaranteed by an Eligible Institution. See
Instructions 1 and 5 to the Letter of Transmittal. If the certificates for
Shares are registered in the name of a person other than the signer of the
Letter of Transmittal, or if payment is to be made or certificates for Shares
not tendered or not accepted for payment are to be issued to a person other than
the registered holder of the certificates surrendered, the tendered certificates
must be endorsed or accompanied by appropriate stock powers, in either case
signed exactly as the name or names of the registered holders or owners appear
on the certificates, with the signatures on the certificates or stock powers
guaranteed as described above. See Instructions 1 and 5 to the Letter of
Transmittal.

     Guaranteed Delivery. If a stockholder desires to tender Shares pursuant to
the Offer and such stockholder's certificates for Shares are not immediately
available or the procedure for book-entry transfer cannot be completed on a
timely basis or time will not permit all required documents to reach the
Depositary prior to the Expiration Date, such stockholder's tender may be
effected if all the following conditions are met:

          (i) such tender is made by or through an Eligible Institution;

          (ii) a properly completed and duly executed Notice of Guaranteed
     Delivery substantially in the form provided by the Purchaser is received by
     the Depositary, as provided below, prior to the Expiration Date; and

          (iii) the certificates for all tendered Shares, in proper form for
     transfer (or a Book-Entry Confirmation with respect to such Shares),
     together with a properly completed and duly executed Letter of Transmittal
     (or facsimile thereof), with any required signature guarantees, or, in the
     case of a book-entry transfer, an Agent's Message, and any other documents
     required by the Letter of Transmittal, are received by the Depositary
     within three trading days after the date of execution of such Notice of
     Guaranteed Delivery. A "trading day," for purposes of the preceding
     sentence, is any day on which The Nasdaq Stock Market is open for business.

                                        5
<PAGE>   8

     The Notice of Guaranteed Delivery may be delivered by hand to the
Depositary or transmitted by facsimile transmission or mail to the Depositary
and must include a guarantee by an Eligible Institution in the form set forth in
such Notice of Guaranteed Delivery.

     Notwithstanding any other provision hereof, payment for Shares accepted for
payment pursuant to the Offer will in all cases be made only after timely
receipt by the Depositary of (i) certificates for such Shares (or a timely
Book-Entry Confirmation of a transfer of such Shares as described in this
Section 2), (ii) a Letter of Transmittal (or copy thereof), properly completed
and duly executed, with any required signature guarantees or, in the case of a
book-entry transfer, an Agent's Message, and (iii) any other documents required
by the Letter of Transmittal. Accordingly, tendering stockholders may be paid at
different times depending upon when certificates for Shares or Book-Entry
Confirmations are actually received by the Depositary. UNDER NO CIRCUMSTANCES
WILL INTEREST BE PAID BY THE PURCHASER ON THE PURCHASE PRICE OF SHARES,
REGARDLESS OF ANY EXTENSION OF THE OFFER OR ANY DELAY IN MAKING SUCH PAYMENT.

     Appointment; Binding Agreement. By executing a Letter of Transmittal as set
forth above (including through delivery of an Agent's Message), the tendering
stockholder will irrevocably appoint designees of the Purchaser as such
stockholder's attorneys-in-fact and proxies in the manner set forth in the
Letter of Transmittal, each with full power of substitution, to the full extent
of such stockholder's rights with respect to the Shares tendered by such
stockholder and accepted for payment by the Purchaser and with respect to any
and all other Shares or other securities or rights issued or issuable in respect
of such Shares on or after the date hereof. All such proxies shall be considered
irrevocable and coupled with an interest in the tendered Shares. Such
appointment will be effective when, and only to the extent that, the Purchaser
accepts for payment Shares tendered by such stockholder as provided herein. Upon
such acceptance for payment, all prior powers of attorney and proxies given by
such stockholder with respect to such Shares or other securities or rights will,
without further action, be revoked and no subsequent powers of attorney and
proxies may be given (and, if given, will not be deemed effective) with respect
thereto. The designees of the Purchaser will be empowered to exercise all voting
and other rights with respect to such Shares or other securities or rights in
respect of any annual, special or adjourned meeting of the Company's
stockholders, or otherwise, as they in their sole discretion deem proper. The
Purchaser reserves the right to require that, in order for Shares to be deemed
validly tendered, immediately upon the Purchaser's acceptance for payment of
such Shares, the Purchaser must be able to exercise full voting and other rights
with respect to such Shares and other securities or rights, including voting at
any meeting of stockholders.

     A tender of Shares pursuant to any one of the procedures described above
will constitute the tendering stockholder's acceptance of the terms and
conditions of the Offer, as well as the tendering stockholder's representation
and warranty that (i) such stockholder has the full power and authority to
tender, sell, assign and transfer the tendered Shares (and any and all other
Shares or other securities issued or issuable in respect of such Shares), and
(ii) when the same are accepted for payment by the Purchaser, the Purchaser will
acquire good and unencumbered title thereto, free and clear of all liens,
restrictions, charges and encumbrances and not subject to any adverse claims.
The Purchaser's acceptance for payment of Shares tendered pursuant to the Offer
will constitute a binding agreement between the tendering stockholder and the
Purchaser upon the terms and subject to the conditions of the Offer.

     Determination of Validity. All questions as to the validity, form,
eligibility (including time of receipt) and acceptance of any tender of Shares
will be determined by the Purchaser in its sole discretion, which determination
will be final and binding. The Purchaser reserves the absolute right to reject
any or all tenders determined by it not to be in proper form or the acceptance
for payment of or payment for which, in the opinion of the Purchaser's counsel,
may be unlawful. The Purchaser also reserves the absolute right to waive any
defect or irregularity in any tender with respect to any particular Shares,
whether or not similar defects or irregularities are waived in the case of other
Shares. No tender of Shares will be deemed to have been validly made until all
defects or irregularities relating thereto have been cured or waived. None of
the Purchaser, Parent, the Depositary, the Information Agent or any other person
will be under any duty to give notification of any defects or irregularities in
tenders or to incur any liability for failure to give any such notification. The
Purchaser's interpretation of the terms and conditions of the Offer (including
the Letter of Transmittal and the instructions thereto) will be final and
binding on all parties.

     Backup Withholding. In order to avoid "backup withholding" of federal
income tax on payments of cash pursuant to the Offer, a stockholder surrendering
Shares in the Offer must provide the Depositary with such stockholder's correct
taxpayer identification number ("TIN") on a Substitute Form W-9 and certify
under penalty of perjury that such TIN is correct and that such stockholder is
not subject to backup withholding. Certain stockholders (including, among
others, all corporations and certain foreign individuals and entities) are not
subject to backup withholding. If a stockholder does not provide its correct TIN
or fails to provide the certifications described above, the Internal Revenue
Service ("IRS") may impose a penalty on such stockholder, and payment of cash to
such stockholder pursuant to the Offer may be subject to backup withholding of
31%. All stockholders surrendering Shares pursuant to the Offer should complete
and sign the main signature form and the Substitute Form W-9 included as part of
the Letter of Transmittal to provide the information and certification necessary
to avoid backup withholding (unless an applicable exemption exists and is proved
in a manner satisfactory to the Purchaser and the Depositary). Noncorporate
foreign stockholders should complete and sign the main signature form and a Form
W-8, Certificate of Foreign Status, a copy of which may be obtained from the
Depositary, in order to avoid backup withholding. See Instruction 9 to the
Letter of Transmittal.

3. WITHDRAWAL RIGHTS.

     Except as otherwise provided in this Section 3, tenders of Shares made
pursuant to the Offer are irrevocable. Shares tendered pursuant to the Offer may
be withdrawn at any time prior to the Expiration Date and, unless already
accepted for payment pursuant to the Offer, may also be withdrawn at any time
after Saturday, October 2, 1999. If purchase of or payment for Shares is delayed
for any reason or if the Purchaser is unable to purchase or pay for Shares for
any reason, then, without prejudice to the Purchaser's rights under the Offer,
tendered Shares may be retained by the Depositary on behalf of the Purchaser and
may not be withdrawn except to the extent that tendering stockholders are
entitled to withdrawal rights as set forth in this Section 3, subject to Rule
14e-1(c) under the Exchange Act, which provides that no person who makes a
tender offer shall fail to pay the consideration offered or to return the
securities deposited by or on behalf of security holders promptly after the
termination or withdrawal of the Offer.

     For a withdrawal of Shares tendered pursuant to the Offer to be effective,
a written or facsimile transmission notice of withdrawal must be timely received
by the Depositary at one of its addresses set forth on the back cover of this
Offer to Purchase. Any notice of withdrawal must specify the name of the person
who tendered the Shares to be withdrawn, the number of Shares to be withdrawn
and the name in which the certificates representing such Shares are registered,
if different from that of the person who tendered the Shares. If certificates
for Shares to be withdrawn have been delivered or otherwise identified to the
Depositary, then, prior to the physical release of such certificates, the serial
numbers shown on such certificates must be submitted to the Depositary and,
unless such Shares have been tendered by an Eligible Institution, the signatures
on the notice of withdrawal must be guaranteed by an Eligible Institution. If
Shares have been tendered pursuant to the procedures for book-entry transfer set
forth in Section 2, any notice of withdrawal must also specify the name and
number of the account at the Book-Entry Transfer Facility to be credited with
the withdrawn Shares and must otherwise comply with such Book-Entry Transfer
Facility's procedures.

     Withdrawals of tenders of Shares may not be rescinded. Any Shares properly
withdrawn will be deemed not validly tendered for purposes of the Offer, but may
be retendered at any subsequent time prior to the Expiration Date by following
any of the procedures described in Section 2.

     All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by the Purchaser, in its sole
discretion, and its determination will be final and binding on all parties. None
of the Purchaser, Parent, the Depositary, the Information Agent or any other
person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.

4. ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES.

     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of any such extension
or amendment), the Purchaser will accept for payment and will pay for all Shares
validly tendered and not withdrawn in accordance with Section 3 prior to the
Expiration Date, promptly after the occurrence of the later of (i) the
Expiration Date and (ii) the satisfaction or waiver of the conditions described
in Section 15. Any determination concerning the satisfaction of such terms and
conditions will be within the discretion of the Purchaser, and such
determination will be final and binding on all tendering stockholders. See
Sections 1 and 15. The Purchaser expressly reserves the right, in its sole
discretion, to delay acceptance for payment of or payment for Shares in order to
comply in whole or in part with any applicable law. Any such delays will be
effected in compliance with Rule 14e-1(c) under the Exchange Act (relating to
the Purchaser's obligation to pay for or to return tendered Shares promptly
after the termination or withdrawal of the Offer).

     In all cases, payment for Shares tendered and accepted for payment pursuant
to the Offer will be made only after timely receipt by the Depositary of (i)
certificates for such Shares or timely Book-Entry Confirmation of a transfer of
such Shares pursuant to the procedures set forth in Section 2, (ii) a properly
completed and duly executed Letter of Transmittal (or a manually signed
facsimile thereof) with all required signature guarantees or, in the case of a
book-entry transfer, an Agent's Message (as defined in Section 2 above) and
(iii) any other documents required by the Letter of Transmittal.

     For purposes of the Offer, the Purchaser will be deemed to have accepted
for payment, and thereby purchased, Shares validly tendered and not withdrawn
as, if and when the Purchaser gives oral or written notice to the Depositary of
the Purchaser's acceptance of such Shares for payment pursuant to the Offer. In
all cases, payment for Shares purchased pursuant to the Offer will be made by
deposit of the purchase price with the Depositary, which will act as agent for
tendering stockholders for the purpose of receiving payment from the Purchaser
and transmitting such payment to tendering stockholders. If, for any reason
whatsoever, acceptance for payment of any Shares tendered pursuant to the Offer
is delayed, or the Purchaser is unable to accept for payment Shares tendered
pursuant to the Offer, then, without prejudice to the Purchaser's rights under
Section 1, the Depositary may, nevertheless, on behalf of the Purchaser, retain
tendered Shares, and such Shares may not be withdrawn, except to the extent that
the tendering stockholders are entitled to withdrawal rights as described in
Section 3 above and as otherwise required by Rule 14e-1(c) under the Exchange
Act. UNDER NO CIRCUMSTANCES WILL INTEREST BE PAID BY THE PURCHASER BECAUSE OF
ANY DELAY IN MAKING SUCH PAYMENT.

     Upon the deposit of funds with the Depositary for the purpose of making
payments to tendering stockholders, the Purchaser's obligation to make such
payment shall be satisfied and tendering stockholders must thereafter look
solely to the Depositary for payment of amounts owed to them by reason of the
acceptance for payment of Shares pursuant to the Offer. The Purchaser will pay
stock transfer taxes with respect to the transfer and sale to it or its order
pursuant to the Offer, except as otherwise provided in Instruction 6 of the
Letter of Transmittal, as well as any charges and expenses of the Depositary and
the Information Agent.

     If any tendered Shares are not purchased pursuant to the Offer because of
an invalid tender or otherwise, the certificates for such Shares will be
returned, and if certificates are submitted for more Shares than are tendered,
new certificates for the Shares not tendered will be sent, in each case without
expense, to the tendering stockholder (or, in the case of Shares delivered by
book-entry transfer of such Shares into the Depositary's account at the
Book-Entry Transfer Facility pursuant to the procedure set forth in Section 2,
such Shares will be credited to an account maintained at the Book-Entry Transfer
Facility), as promptly as practicable after the expiration or termination of the
Offer.

     The Purchaser reserves the right to transfer or assign, in whole or from
time to time in part, to Parent, or to one or more direct or indirect wholly
owned subsidiaries of Parent, the right to purchase Shares tendered pursuant to
the Offer. Any such transfer or assignment will not relieve the Purchaser of its
obligations under the Offer and will in no way prejudice the rights of tendering
stockholders to receive payment for Shares validly tendered and accepted for
payment pursuant to the Offer.
                                        8
<PAGE>   11

     If, prior to the Expiration Date, the Purchaser increases the price being
paid for Shares accepted for payment pursuant to the Offer, such increased
consideration will be paid to all stockholders whose Shares are purchased
pursuant to the Offer, whether or not such Shares were tendered prior to such
increase in consideration.

5. CERTAIN FEDERAL INCOME TAX CONSEQUENCES.

     The following is a summary of certain United States federal income tax
consequences of the Offer and the Merger to beneficial owners of Shares whose
Shares are purchased pursuant to the Offer or whose Shares are converted into
the Offer Price in the Merger. The discussion is for general information only
and does not purport to consider all aspects of federal income taxation that may
be relevant to beneficial owners of Shares. The discussion is based on current
provisions of the Internal Revenue Code of 1986, as amended (the "Code"),
existing, proposed and temporary regulations issued thereunder and
administrative and judicial interpretations thereof, all of which are subject to
change. The discussion applies only to beneficial owners of Shares in whose
hands Shares are capital assets within the meaning of Section 1221 of the Code,
and may not apply to Shares received pursuant to the exercise of employee stock
options or otherwise as compensation, or to certain types of beneficial owners
of Shares (such as insurance companies, tax-exempt organizations and
broker-dealers) who may be subject to special rules. This discussion does not
discuss the federal income tax consequences to a beneficial owner of Shares who,
for United States federal income tax purposes, is a non-resident alien
individual, a foreign corporation, a foreign partnership or a foreign estate or
trust, nor does it consider the effect of any foreign, state or local tax laws.

     BECAUSE INDIVIDUAL CIRCUMSTANCES MAY DIFFER, EACH BENEFICIAL OWNER OF
SHARES SHOULD CONSULT SUCH BENEFICIAL OWNER'S OWN TAX ADVISOR TO DETERMINE THE
APPLICABILITY OF THE RULES DISCUSSED BELOW TO SUCH BENEFICIAL OWNER AND THE
PARTICULAR TAX EFFECTS TO SUCH BENEFICIAL OWNER OF THE OFFER AND THE MERGER,
INCLUDING THE APPLICATION AND EFFECT OF FOREIGN, STATE, LOCAL AND OTHER TAX
LAWS.

     Sales of Shares pursuant to the Offer (and the receipt of cash by
stockholders of the Company pursuant to the Merger) will be taxable transactions
for federal income tax purposes under the Code, and may also be taxable
transactions under applicable foreign, state, local and other tax laws.
Generally, for federal income tax purposes, a tendering stockholder will
generally recognize gain or loss equal to the difference between the amount of
cash received by the stockholder pursuant to the Offer (or pursuant to the
Merger) and the aggregate tax basis in the Shares tendered by the stockholder
and purchased pursuant to the Offer (or converted pursuant to the Merger). Gain
or loss will be calculated separately for each block of Shares (i.e., Shares
acquired at the same time and price) tendered and purchased pursuant to the
Offer (or converted pursuant to the Merger).

     In general, cash received in respect of Shares whose holders exercise
appraisal rights under the Delaware Law will result in the recognition of
capital gain or loss to the beneficial owner of such Shares. Any such beneficial
owner should consult such owner's tax advisor in that regard.

     If tendered Shares are held by a tendering stockholder as capital assets,
gain or loss recognized by the tendering stockholder will be capital gain or
loss, which will be long-term capital gain or loss if the tendering
stockholder's holding period for the Shares exceeds one year. Long-term capital
gains recognized by a tendering individual stockholder will generally be taxed
at a maximum federal income tax rate of 20%. The ability to deduct capital
losses is subject to limitations.

     A stockholder (other than certain exempt stockholders including, among
others, all corporations) that tenders Shares may be subject to 31% backup
withholding unless the stockholder provides its TIN and certifies that such
number is correct or properly certifies that it is awaiting a TIN and certifies
as to no loss of exemption from backup withholding and otherwise complies with
the applicable requirements of the backup withholding rules. A stockholder that
does not furnish its correct TIN or that does not otherwise establish a basis
for an exemption from backup withholding may be subject to a penalty imposed by
the IRS. Each stockholder should complete and sign the Substitute Form W-9
included as part of the Letter of Transmittal so as to provide the information
and certification necessary to avoid backup withholding (unless an applicable
exemption exists and is proved in a manner satisfactory to the Purchaser and the
Depositary).
                                        9
<PAGE>   12

     If backup withholding applies to a stockholder, the Depositary is required
to withhold 31% from payments to such stockholder. Backup withholding is not an
additional tax. Rather, the amount of the backup withholding can be credited
against the federal income tax liability of the person subject to the backup
withholding, provided that the required information is given to the IRS. If
backup withholding results in an overpayment of tax, a refund can be obtained by
the stockholder upon filing an income tax return.

6. PRICE RANGE OF SHARES; DIVIDENDS.

     The Company's Shares are quoted for trading on the Nasdaq National Market

</TABLE>

     On July 27, 1999, the last full day of trading prior to the public
announcement of the execution of the Merger Agreement, the closing price per
Share as reported on the Nasdaq National Market was $12.00. On August 2, 1999,
the last full day of trading prior to the commencement of the Offer, the closing
price per Share as reported on the Nasdaq National Market was $15.00.

     STOCKHOLDERS ARE URGED TO OBTAIN CURRENT MARKET QUOTATIONS FOR THE SHARES.

     According to the Company's Annual Report on Form 10-K for the year ended
December 31, 1998, beginning in the third quarter of 1995, the Company has paid
regular quarterly dividends of $.01 per Share. With respect to the current
quarter, the Company changed the record date of its previously declared regular
quarterly cash dividend of $.01 per share from August 16, 1999 to September 15,
1999, payable September 30, 1999. Holders whose Shares are accepted for payment
by the Purchaser prior to the record date for the previously declared dividend
will not be entitled to receive the dividend with respect to those Shares.

7. CERTAIN EFFECTS OF THE TRANSACTION.

     Parent and the Purchaser intend to seek to cause the Company to terminate
the registration of the Shares under the Exchange Act as soon after the
completion of the Offer as the requirements for such termination are met. If
registration of the Shares is not terminated prior to the Merger, the
registration of the Shares under the Exchange Act will be terminated following
the consummation of the Merger.

     Market for the Shares. The purchase of Shares pursuant to the Offer will
reduce the number of holders of Shares and the number of Shares that might
otherwise trade publicly, which could adversely affect the liquidity and market
value of the remaining Shares held by the public.

     Depending upon the number of Shares purchased pursuant to the Offer, the
Shares may no longer meet the requirements for continued designation on the
Nasdaq National Market. To maintain such designation, a

                                       10
<PAGE>   13

security must substantially meet one of two maintenance standards. The first
maintenance standard requires that (i) there be at least 750,000 publicly held
shares, (ii) the publicly held shares have a market value of at least $5
million, (iii) the issuer have net tangible assets of at least $4 million, (iv)
there be at least 400 stockholders of round lots, (v) the minimum bid price per
share be at least $1.00 and (vi) there be at least two registered and active
market makers. The second maintenance standard requires that (i) the issuer have
either (a) a market capitalization of at least $50 million or (b) total assets
and total revenue of at least $50 million each for the most recently completed
fiscal year or two of the last three most recently completed fiscal years, (ii)
there be at least 1,100,000 shares publicly held, (iii) the publicly held shares
have a market value of at least $15 million, (iv) the minimum bid price per
share be at least $5.00, (v) there be at least 400 stockholders of round lots
and (vi) there be at least four registered and active market makers.

     If these standards for continued designation on the Nasdaq National Market
are not met, the Shares might nevertheless continue to be included in the Nasdaq
SmallCap Market. Continued inclusion in the Nasdaq SmallCap Market, however,
would require that (i) there be at least 300 round lot holders, (ii) there be at
least 500,000 publicly held shares, (iii) the publicly held shares have a market
value of at least $1 million, (iv) there be at least two registered and active
market makers, of which one may be entering stabilizing bids and (v) the issuer
have either (a) net tangible assets of at least $2 million, (b) market
capitalization of at least $35 million or (c) net income of at least $500,000 in
the most recently completed fiscal year or in two of the last three most
recently completed fiscal years. Shares held directly or indirectly by
directors, officers or beneficial owners of more than 10% of the Shares are not
considered as being publicly held for the purpose of determining whether either
of The Nasdaq Stock Market listing criteria are met. According to the Company,
as of July 28, 1999, there were 9,673,224 Shares outstanding (not including
Shares reserved for issuance pursuant to outstanding stock options or Shares
held by the Company or any direct or indirect subsidiary of the Company), held
by approximately 106 holders of record.

     If the purchase of Shares pursuant to the Offer causes the Shares to no
longer meet the requirements for continued inclusion in the Nasdaq National
Market or the Nasdaq SmallCap Market as a result of a reduction in the number or
market value of publicly held Shares or the number of round lot holders or
otherwise, as the case may be, the market for Shares could be adversely
affected. It is possible that the Shares would continue to trade in the
over-the-counter market and that price quotations would be reported by other
sources. The extent of the public market for the Shares and the availability of
such quotations, however, would depend upon the number of holders of Shares
remaining at such time, the interest in maintaining a market in Shares on the
part of securities firms, the possible termination of registration of the Shares
under the Exchange Act, as described below, and other factors.

     Exchange Act Registration. Registration of the Shares under the Exchange
Act may be terminated upon application of the Company to the SEC if the Shares
are neither listed on a national securities exchange nor held by 300 or more
holders of record. Termination of registration of the Shares under the Exchange
Act would, subject to Section 15(d) of the Exchange Act, substantially reduce
the information required to be furnished by the Company to its stockholders and
to the SEC and would make certain provisions of the Exchange Act no longer
applicable to the Company, such as the short-swing profit recovery provisions of
Section 16(b) of the Exchange Act, the requirement of furnishing a proxy or
information statement pursuant to Section 14(a) or (c) of the Exchange Act in
connection with stockholders' meetings and the related requirement of furnishing
an annual report to stockholders and the requirements of Rule 13e-3 under the
Exchange Act with respect to "going private" transactions. Furthermore, the
ability of "affiliates" of the Company and persons holding "restricted
securities" of the Company to dispose of such securities pursuant to Rule 144 or
144A issued under the Securities Act of 1933, as amended, may be impaired or
eliminated. Parent and the Purchaser intend to seek to cause the Company to
apply for termination of registration of the Shares under the Exchange Act as
soon after the completion of the Offer as the requirements for such termination
are met.

     If registration of the Shares is not terminated prior to the Merger, then
trading of the Shares will cease to be reported on the Nasdaq National Market
and the registration of the Shares under the Exchange Act will be terminated
following the consummation of the Merger.

                                       11
<PAGE>   14

     Margin Regulations. The Shares are currently "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System (the
"Federal Reserve Board"), which has the effect, among other things, of allowing
brokers to extend credit on the collateral of the Shares. Depending upon factors
similar to those described above regarding listing and market quotations, it is
possible that, following the Offer, the Shares would no longer constitute
"margin securities" for the purposes of the margin regulations of the Federal
Reserve Board and therefore could no longer be used as collateral for loans made
by brokers or other institutions. If registration of Shares under the Exchange
Act were terminated, the Shares would no longer be "margin securities."

8. CERTAIN INFORMATION CONCERNING THE COMPANY.

     Except as otherwise set forth herein, the information concerning the
Company contained in this Offer to Purchase, including financial information,
has been furnished by the Company or has been taken from or based upon publicly

    The United States dollar exchange rate, expressed in dollars per pound, on
    June 30, 1999 was 1.58, and the six month average rate for the period ended
    June 30, 1999 was 1.61 and for the period ended June 30, 1998 was 1.65. The
    statement of income data set forth above was based on the average exchange
    rate for the indicated period. The balance sheet data set forth above was
    based on the exchange rate at the date indicated.

(2) Turnover and total operating profit has declined since December 31, 1996
    primarily due to the disposal of non-core businesses.

(3) The balance sheet data as of June 30, 1999 reflects the new UK accounting
    standard Financial Reporting Standard ("FRS") 12. The balance sheet data for
    the years ended December 31, 1998 and 1997 has not been restated for FRS12.

(4) The net assets were reduced in 1997 following the return of capital to
    shareholders totaling L223.8m.

     Although generally accepted accounting principles in the United Kingdom
("UK GAAP") differ in certain significant respects from generally accepted
accounting principles in the United States ("US GAAP"), Parent believes that the
differences are not material to a decision by a holder of Shares whether to
sell, tender or hold any Shares because any such differences would not affect
the ability of the Purchaser to obtain sufficient funds to pay for the Shares to
be acquired pursuant to the Offer. While the following is not a comprehensive
summary of all the differences between UK GAAP and US GAAP, other differences
are unlikely to have a significant effect on the consolidated income or
shareholders' funds of Caradon plc, who will provide the Purchaser with the
funds sufficient to consummate the Offer, the Merger and the other transactions
contemplated by the Merger Agreement.

     Goodwill and US Purchase Accounting. Under US GAAP and UK GAAP, purchase
consideration in respect of subsidiaries acquired is allocated on the basis of
appraised values to the various net assets of the subsidiaries at the dates of
acquisition, and any net balance is treated as goodwill. US GAAP requires
goodwill to be recognized as an asset and amortized over its estimated useful
life, not to exceed 40 years. Under UK GAAP, with respect to periods ending on
or prior to December 23, 1998, goodwill was written off directly against
reserves. With respect to periods ending after December 23, 1998, goodwill is
recognized as an asset and amortized over its estimated useful life, presumed
not to exceed 20 years.

     Ordinary Dividends. Under UK GAAP, final ordinary dividends are provided
for in the fiscal year in respect of which they are recommended by the board of
directors for approval by the shareholders. Under US GAAP, such dividends are
not provided for until declared by the board of directors.

     Deferred Taxation. Under UK GAAP, no provision is made for deferred
taxation if there is reasonable evidence that such deferred taxation will not be
payable in the foreseeable future, and deferred tax assets are generally not
recognized under UK GAAP unless they are likely to be recovered in the
foreseeable future (i.e., one year from the balance sheet date). Under US GAAP,
deferred tax assets and liabilities are recognized in full, and any net deferred
tax assets are then assessed for probable recoverability. As long as it is more
likely than not that sufficient future taxable income will be available to
utilize the deferred tax assets, no valuation allowance is provided.

     Tangible Fixed Assets. Under UK GAAP, companies are permitted to carry
tangible fixed assets at valuation (generally current cost or market value as of
the date of last valuation). Under US GAAP, revaluation of tangible fixed assets
is generally not permitted outside of purchase accounting.

     Neither the Purchaser, Parent nor Caradon plc is subject to the reporting
requirements of the Exchange Act and, therefore, they do not file reports or
other information with the SEC relating to their business, financial condition
or other matters.

     Except as described in this Offer to Purchase, neither Caradon plc, Parent

10. SOURCE AND AMOUNT OF FUNDS.

     The total amount of funds required by the Purchaser to consummate the Offer
and the Merger is expected to be approximately $155 million (assuming the
exercise of all options to purchase Shares prior to the Expiration Date),
excluding related fees and expenses.

     Caradon plc will obtain the amounts described in the preceding paragraph
from cash on hand and from its existing credit facilities with various financial
institutions. The total committed funds currently available to Caradon plc under
existing credit facilities aggregate approximately $640 million. The credit
facilities include various five-year facilities (with Bank of America National
Trust & Savings Association, Barclays Bank plc, Den Danske Bank, HSBC (Midland
Bank plc), National Westminster Bank plc, Royal Bank of Canada Europe Limited,
UBS AG and Westdeutsche Landesbank Girozentrale) and various 364-day facilities
(with Barclays Bank plc, Den Danske Bank, HSBC (Midland Bank plc), National
Westminster Bank plc, Royal Bank of Canada Europe Limited and Westdeutsche
Landesbank Girozentrale).

     The credit facility agreements described above are in each case between the
specified bank and Caradon plc. The facilities are floating rate, priced at
margins over LIBOR not exceeding .5% p.a. (plus Bank of England Mandatory Costs
where applicable).

     There are no unusual or material conditions to be satisfied prior to
drawing funds under the described credit facilities. The facilities are
unsecured but include a negative pledge on the assets of the Caradon group
(subject to certain exceptions). The facilities require compliance with an
interest coverage ratio covenant, calculated on a consolidated basis. The
facilities also require compliance with certain operating covenants that limit,
among other things, disposal of assets (subject to certain exceptions) and the
creation of obligations senior to drawings under the facilities. The foregoing
summary of credit facilities which may be drawn upon in connection with the
Offer and the Merger is qualified in its entirety by reference to the text of
such credit facility agreements, copies of which are filed as exhibits to the
Schedule 14D-1 (as defined below).

     The amounts available to Caradon plc under the described credit facilities
and cash on hand exceed the amount that would be required to allow the Purchaser
to fully consummate the Offer and the Merger.

     Caradon plc currently plans to repay borrowings under the credit facilities
out of operating cash flow and future financings, although Caradon plc has no
current specific plan with respect thereto. Such decisions when made will be
based on Caradon plc's review from time to time of the advisability of
particular actions, as well as on prevailing interest rates and financial and
other economic conditions.

     This description of Caradon plc's existing credit facilities is a summary
only and is not intended to be a complete description of all the terms thereof.
Reference is made to the full text thereof, copies of which are filed as
exhibits to the Tender Offer Statement on Schedule 14D-1 filed by Caradon plc,

14D-1 may be examined at the same places and in the same manner as set forth
with respect to the Company in Section 8.

11. BACKGROUND OF THE OFFER; PAST CONTACTS, TRANSACTIONS AND NEGOTIATIONS WITH
THE COMPANY.

     In the ordinary course of Caradon plc's long-term strategic planning,
Caradon plc and its affiliates, including Parent, are often involved in
discussions and investigations concerning possible acquisitions and business
combinations.

     In furtherance of Caradon plc's strategic objectives to expand the size and
scope of its North American business operations, on June 10, 1999, Caradon plc,
Parent and the Company entered into a confidentiality agreement, as described in
Section 13 ("The Merger Agreement and the Stockholder Agreements"), and was
furnished a confidential offering memorandum which was being made available to
potential purchasers of the Company. In response to Wasserstein Perella's
solicitation of interest and based upon the confidential offering memorandum, in
late June Caradon plc submitted a non-binding indication of interest concerning
the potential acquisition of the Company, and was thereafter invited to
participate in a second round of bidding.

     Caradon plc submitted a written proposal to acquire the Company on July 19,
which included a markup of the draft merger agreement. Caradon plc's proposal
provided for a one-step merger, subject to stockholder approval, in which each
outstanding Share would be converted into the right to receive cash, and
proposed stockholder agreements providing for a grant of a proxy by certain
stockholders of the Company, including AIP.

     On July 21, 1999, a representative of Wasserstein Perella, on behalf of the
Company, telephoned a representative of the financial advisor for Caradon plc
and Parent, advised him that the Company preferred Parent's proposal to be
structured as a tender offer with a back-end merger, and stated that the Company
was prepared to work with Caradon plc and Parent toward entering into a
definitive agreement and to recommend such proposal to the Company's Board of
Directors, subject to Parent improving its offer and the satisfactory
negotiation of definitive documentation. Caradon plc and Parent indicated a
willingness to improve its offer on this basis.

     On July 24, the Company agreed to enter into exclusive negotiations with
Caradon plc and Parent for a four-day period in order to induce Parent to
improve its offer. From July 24 to July 26, representatives of Caradon plc and
Parent and the Company met at the affiliated offices of Skadden, Arps, Slate,
Meagher & Flom LLP in Chicago to negotiate a definitive agreement and resolve
several open issues, including whether there would be any post-closing survival
of representations and warranties and related indemnification, the amount of the
termination fee, the circumstances under which the termination fee would become
payable and the circumstances under which the Company's Board of Directors could
enter into discussions with another party regarding a Takeover Proposal (as
defined in the Merger Agreement).

     At a meeting held on July 27, 1999, the Board of Directors of the Company
unanimously approved the Merger Agreement, the Offer and the Merger and
determined that the terms of the Offer and the Merger are fair to and in the
best interests of the holders of Shares, and unanimously recommended that the
Company's stockholders accept the Offer and tender their Shares pursuant to the
Offer. The Merger Agreement, the Offer and the Merger were previously approved
by the Boards of Directors of Caradon plc, Parent and the Purchaser on July 26,
1999.

     Later that night, Parent, the Purchaser and the Company executed and
delivered the Merger Agreement, and Parent, the Purchaser and the designated
stockholders executed and delivered the Stockholder Agreements. Prior to the
opening of trading on the Nasdaq National Market on Wednesday, July 28, 1999,
Parent and the Company jointly announced that the Merger Agreement had been
signed and that the Purchaser intended to commence the Offer. A separate press
release was issued by Caradon plc in the United Kingdom.

     On August 3, 1999, the Purchaser commenced the Offer.

12. PURPOSE OF THE OFFER AND THE MERGER; PLANS FOR THE COMPANY.

     The purpose of the Offer and the Merger is to enable Parent to acquire
control of, and the entire equity interest in, the Company. The Offer, as the
first step in the acquisition of the Company, is intended to facilitate the
acquisition of all the Shares. Parent will cause the Merger to be consummated as
soon as practicable following the consummation of the Offer. The purpose of the
Merger is to acquire all Shares not purchased pursuant to the Offer or
otherwise. Following the Merger, the Company would become an indirect wholly
owned subsidiary of Parent.

     It is expected that, initially following the Merger, the business and
operations of the Company and its subsidiaries will continue without substantial
change. Parent intends to conduct an extensive review of the Company and its
subsidiaries and their assets, corporate structure, operations, properties,
policies, management and personnel and to consider what, if any, changes would
be desirable in light of the circumstances then existing. Parent reserves the
right to take such actions and make such changes as it deems desirable. Such
changes could include changes in the Company's business, corporate structure,
capitalization, management or personnel.

     Except as described above, neither Parent, the Purchaser nor Caradon plc
have any present plans or proposals that would relate to, or result in, any
extraordinary corporate transaction involving the Company, such as a merger,
reorganization or liquidation involving the Company or any of its subsidiaries,
a sale or transfer of a material amount of assets of the Company or any of its
subsidiaries, or any material change in the Company's business or corporate
structure or composition of its management or personnel.

     The Merger Agreement provides that the directors of the Purchaser,
immediately prior to the Effective Time of the Merger, will be the initial
directors of the Company after the Merger. For the potential effects of the
Offer and the Merger on the listing of the Shares on the Nasdaq National Market
and their registration under the Exchange Act, see Section 7.

13. THE MERGER AGREEMENT AND THE STOCKHOLDER AGREEMENTS.

     The following summary of certain provisions of the Merger Agreement and the
Stockholder Agreements among Parent, the Purchaser and certain stockholders of
the Company, copies of which are filed as Exhibits (c)(1), (c)(2) and (c)(3),
respectively, to the Schedule 14D-1, is qualified in its entirety by reference
to the texts of the Merger Agreement and the Stockholder Agreements. The Merger
Agreement and the Stockholder Agreements may be examined at the same places and
in the same manner as set forth with respect to the Company in Section 8.

THE MERGER AGREEMENT

     As of July 28, 1999, Parent, the Purchaser and the Company entered into the
Merger Agreement, pursuant to which the Purchaser agreed to make the Offer. The
following description of the Merger Agreement does not purport to be complete
and is qualified by reference to the text of the Merger Agreement.

     The Offer. The Merger Agreement provides that the Purchaser will commence
the Offer and that, upon the terms and subject to the prior satisfaction or
waiver of the conditions of the Offer, the Purchaser will purchase all Shares
validly tendered pursuant to the Offer. The obligation of the Purchaser to
accept for payment and pay for Shares tendered is subject to the Minimum
Condition, which is the valid tender and non-withdrawal prior to the expiration
of the Offer of at least a majority of the Shares then outstanding on a fully
diluted basis, and to the satisfaction of the conditions described in Annex A to
the Merger Agreement. The Merger Agreement provides that the Purchaser may not
amend or waive the Minimum Condition, decrease the Offer Price or change the
form of consideration payable in the Offer, decrease the number of Shares
sought, or otherwise amend any other condition of the Offer in any manner
adverse to the holders of the Shares without the prior written consent of the
Company; provided, that if on the initial scheduled Expiration Date of the
Offer, all conditions of the Offer shall not have been satisfied or waived,
Purchaser may, in its sole discretion, extend the Expiration Date. The Purchaser
shall, on the terms and subject to the prior satisfaction or waiver of the
conditions of the Offer and as promptly as practicable after the expiration of
the Offer, accept for payment Shares tendered; provided that if immediately
prior to the initial Expiration Date of the Offer (as it may be extended) the
number of Shares tendered and not withdrawn pursuant to the Offer is less than
90%

                                       19
<PAGE>   22

of the outstanding Shares, the Purchaser may, in its sole discretion, extend the
Expiration Date of the Offer for a period not to exceed ten business days,
notwithstanding that all conditions to the Offer are satisfied as of such
Expiration Date.

     Designation of Directors. The Merger Agreement provides that, promptly
after the Purchaser acquires any Shares pursuant to the Offer, and from time to
time thereafter as the Purchaser acquires Shares, Parent will be entitled to
designate such number of directors, rounded up to the next whole number, on the
Company's Board of Directors as is equal to the product of (i) the total number
of directors on the Board of Directors (giving effect to the directors
designated by Parent) multiplied by (ii) the percentage of outstanding Shares
then beneficially owned by the Purchaser. However, until the Effective Time, the
Board of Directors of the Company will continue to have at least one Independent
Director. If no Independent Directors remain on the Company's Board of
Directors, the other directors will designate one person to fill such vacancy
who meets the eligibility requirements for Independent Directors. The Company
has agreed either to increase (but not above 10 persons) the size of the Board
of Directors of the Company or obtain the resignation of such number of
directors as is necessary to enable the Purchaser's designees to be elected or
appointed to the Board. The Company's obligation to appoint Parent's designees
to the Board of Directors of the Company is subject to compliance with Section
14(f) of the Exchange Act and Rule 14f-1 issued thereunder. Following the
election of Parent's designees, the affirmative vote of a majority of the
Independent Directors will be required to amend or terminate the Merger
Agreement on behalf of the Company, exercise or waive any of the Company's
rights, benefits or remedies thereunder if such exercise or waiver materially
and adversely affects holders of Shares other than Parent or the Purchaser,
extend the time for the performance of the Purchaser's obligations thereunder or
take any other action by the Company under the Merger Agreement required to be
taken by the Company's Board of Directors, if such action materially and
adversely affects stockholders other than Parent or the Purchaser.

     The Merger. The Merger Agreement provides that at the Effective Time the
Purchaser will be merged with and into the Company, and the Company will
continue as the Surviving Corporation. The Effective Time of the Merger will be
the time of filing with the Secretary of State of the State of Delaware of a
Certificate of Merger, or such later time as may be specified in the Certificate
of Merger. The parties expect to file the Certificate of Merger as soon as
practicable following the closing of the Merger, which will take place on the
second business day after the conditions to the parties' obligations to effect
the Merger have been satisfied or waived, unless another date is otherwise
agreed.

     Each Share issued and outstanding immediately prior to the Effective Time
(other than Shares held (i) in the treasury of the Company or by Parent or by
any direct or indirect wholly owned subsidiary of Parent immediately before the
Effective Time, or (ii) by stockholders, if any, who are entitled to and who
properly exercise appraisal rights under the Delaware Law) will be converted
into the right to receive the Offer Price. Each share of common stock of the
Purchaser issued and outstanding immediately prior to the Effective Time will be
converted into one share of common stock of the Surviving Corporation.

     The Certificate of Incorporation of the Company, as in effect immediately
before the Effective Time, will be the Certificate of Incorporation of the
Surviving Corporation and will be amended to read as set forth in Exhibit A to
the Merger Agreement. The Bylaws of the Purchaser will be the Bylaws of the
Surviving Corporation. The directors of the Purchaser immediately before the
Effective Time will be the initial directors of the Surviving Corporation, and
the officers of the Company immediately before the Effective Time will be the
initial officers of the Surviving Corporation.

     Conditions to the Merger. The respective obligations of Parent and the
Purchaser, on the one hand, and the Company, on the other hand, to effect the
Merger are subject to the satisfaction on or prior to the Closing Date (as
defined in the Merger Agreement) of each of the following conditions:

          (i) the Purchaser shall have made or caused to be made the Offer and
     shall have purchased or caused to be purchased Shares pursuant to the
     Offer, provided that such condition shall be deemed to have been satisfied
     with respect to the obligation of Parent and the Purchaser to consummate
     the Merger if the Purchaser fails to accept for payment or pay for Shares
     pursuant to the Offer in violation of the terms of the Offer or the Merger
     Agreement;
                                       20
<PAGE>   23

          (ii) the Merger Agreement shall have been approved and adopted by the
     requisite vote of the holders of Shares, if required by the Delaware Law;
     and

          (iii) no statute, rule or regulation shall have been enacted or
     promulgated, no final, nonappealable judgment, writ, decree, order or
     injunction shall have been entered or enforced, and no other legally
     binding, final and nonappealable action shall have been taken by any
     domestic or foreign government, governmental, administrative or regulatory
     authority or agency or by any court or tribunal of competent jurisdiction,
     domestic or foreign, that has the effect of making illegal, restraining,
     restricting or precluding consummation of the Merger.

     Recommendation. The Company represents in the Merger Agreement that the
Board of Directors of the Company has (i) duly approved and adopted the Merger
Agreement and the transactions contemplated by the Merger Agreement, including

Company, and (iii) resolved to recommend that the Company's stockholders accept
the Offer and approve and adopt the Merger Agreement. The Company has agreed to

containing such recommendations and to mail such Schedule 14D-9 to the
stockholders of the Company at the time the Offer to Purchase and related
documents are first mailed to the stockholders.

     Stock Options. At or immediately prior to the Effective Time, each
outstanding option to purchase Shares (the "Options") issued under the Company's
Stock Option Plan dated December 17, 1993, as amended, and any other stock-based
incentive plan or arrangement of the Company (collectively, the "Stock Plans")
will be canceled and, in consideration of such cancellation, the holders of such
Options will receive for each Share subject to such Options a cash payment
(subject to tax withholding) equal to the product of (i) the excess, if any, of
the Offer Price over the per Share exercise price of the applicable Option and
(ii) the number of Shares subject to that Option which have not already been
exercised. The Company will take all actions necessary to (i) cause the Stock
Plans to terminate as of the Effective Time, (ii) delete as of the Effective
Time the provision in any other benefit plan of the Company providing for the
issuance, transfer or grant of capital stock of the Company, and (iii) ensure
that following the Effective Time no holder of Options or any participant in any
Stock Plan or other Company benefit plan shall have any right thereunder to
acquire any capital stock of the Company or the Surviving Corporation.

     Interim Operations; Covenants. Pursuant to the Merger Agreement, the
Company has agreed that, except (i) as expressly contemplated by the Merger
Agreement, in compliance with applicable laws, (ii) for the payment of remaining
amounts due to American Industrial Partners Management Company, Inc. pursuant to
a management agreement, or (iii) as agreed to in writing by Parent prior to the

Directors of the Company (the "Appointment Date"), the business of the Company
will be conducted only in the ordinary and usual course consistent with past
practice and in compliance with applicable laws, and each of the Company and its
subsidiaries will use its reasonable best efforts to preserve and protect its
business organization, properties and assets intact and maintain its existing
relations with customers, suppliers, employees, creditors and business partners
to the end that its goodwill and business shall be unimpaired in any material
respect as of the Effective Time.

     The Company has also agreed that it will not, directly or indirectly:

          (i) issue, sell, transfer or pledge or agree to sell, transfer or
     pledge any capital stock of the Company or any of its subsidiaries

     under "-- The Merger" or any of the conditions to the Offer described in
     Section 15 of this Offer to Purchase not being satisfied, or would make any
     representation or warranty of the Company contained in the Merger Agreement
     inaccurate in any respect at, or as of any time prior to, the Effective
     Time, or that would materially impair the ability of the Company to
     consummate the Merger in accordance with the terms of the Merger Agreement
     or materially delay such consummation; or

          (xxvi) enter into an agreement, contract, commitment or arrangement to
     do any of the foregoing, or authorize, recommend, propose or announce an
     intention to do any of the foregoing.

     Company Stockholder Meeting. If required by applicable law, the Company has
agreed to (i) hold a special meeting of its stockholders as soon as practicable
following acceptance for payment of Shares pursuant
                                       23
<PAGE>   26

to the Offer for the purpose of approving the Merger and adopting the Merger
Agreement, (ii) prepare and file with the SEC a preliminary proxy statement or
information statement relating to the Merger Agreement, and (iii) use its best
efforts to obtain the necessary approvals of the Merger and the Merger Agreement
by its stockholders. Parent and the Purchaser have agreed to vote all Shares
owned by them in favor of approval of the Merger Agreement. However, if Parent
or the Purchaser acquire at least 90% of the outstanding Shares, the parties
will, at the request of Parent, cause the Merger to become effective as soon as
practicable after such acquisition without a meeting of stockholders of the
Company in accordance with the Delaware Law.

     No Solicitation. In the Merger Agreement, the Company agreed to cease and
cause to be terminated any existing activities, discussions or negotiations, if
any, with any parties conducted prior to the date of the Merger Agreement with
respect to any Takeover Proposal. "Takeover Proposal" means any tender or
exchange offer involving the Company, any proposal for a merger, consolidation
or other business combination involving the Company, any proposal or offer to
acquire in any manner greater than a 20% equity interest in, or greater than a
20% portion of the business or assets of, the Company, any proposal or offer
with respect to any recapitalization or restructuring with respect to the
Company or any proposal or offer with respect to any other transaction similar
to any of the foregoing with respect to the Company, other than pursuant to the
Transactions.

     In addition, the Company will not, will cause its officers and directors
not to, and will use its reasonable best efforts to ensure that its employees
(other than its officers or directors), investment bankers, attorneys,
accountants and other agents and representatives do not, directly or indirectly:
(i) initiate, solicit or encourage, or take any action to facilitate the making
of, any offer or proposal which constitutes or is reasonably likely to lead to
any Takeover Proposal, (ii) enter into any agreement with respect to any
Takeover Proposal, or (iii) engage in any negotiations or discussions with, or
provide any information or data to, any person (other than Parent or any of its
affiliates or representatives) relating to any Takeover Proposal. However, the
Company or its Board of Directors is not prohibited from (i) taking and
disclosing to the Company's stockholders a position with respect to a tender or
exchange offer by a third party pursuant to Rules 14d-9 and 14e-2 promulgated
under the Exchange Act or (ii) making such other disclosure to the Company's
stockholders as the Board of Directors of the Company determines in good faith
after consulting with its counsel and determining that the failure to make such
disclosure would constitute a breach of the fiduciary duties of the Board of
Directors of the Company under applicable law.

     Notwithstanding the foregoing, prior to the acceptance of Shares pursuant
to the Offer, the Company may, in response to an unsolicited written proposal
with respect to a Takeover Proposal from a financially capable third party that
contains no financing condition, furnish information to, and negotiate, explore
or otherwise engage in substantive discussions with, such third party, in each
case only if (i) the Board of Directors of the Company determines in good faith
by a majority vote, after consultation with its financial advisors and after
receipt of advice of the outside legal counsel of the Company, that failing to
take such action would constitute a breach of the fiduciary duties of the Board,
and (ii) the Company obtains a confidentiality and standstill agreement no less
favorable to the Company than the Confidentiality Agreement entered into with
Parent. The Company agreed to promptly advise Parent in writing of the receipt
of any inquiries or proposals relating to a Takeover Proposal, indicating the
name of the person making such inquiry or proposal, the terms and conditions
thereof and any actions taken pursuant to the foregoing sentence. The Company
will also promptly furnish to Parent a copy of any written inquiry or proposal
relating to a Takeover Proposal.

     Indemnification and Insurance. Pursuant to the Merger Agreement, in the
event of any threatened or actual claim, action, suit, proceeding or
investigation, whether civil, criminal or administrative, including any such
claim, action, suit, proceeding or investigation by or in the right of the
Company or any of its subsidiaries, in which any of the present or former
officers or directors (the "Indemnified Parties") of the Company is, or is
threatened to be, made a party by reason of the fact that he is or was, prior to
the Effective Time, a director, officer, employee or agent of the Company or any
of its subsidiaries or is or was, prior to the Effective Time, serving as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise at the request of the Company or any of its
subsidiaries, whether such claim arises before or after the Effective Time, the
Company and, after the Effective Time, the Surviving Corporation, jointly and
severally, shall indemnify and hold harmless, as and to the same extent and on
the same terms and conditions
                                       24
<PAGE>   27

provided for in the Company's Certificate of Incorporation, Bylaws and certain
indemnification agreements entered into between the Company and the members of
the Special Committee (as defined in the Merger Agreement) in effect on the date
of the Merger Agreement (to the extent consistent with applicable laws) each
such Indemnified Party against any losses, claims, damages, liabilities, costs,
expenses (including reasonable attorneys' fees and expenses), judgments, fines
and amounts paid in settlement in connection with any such claim, action, suit,
proceeding or investigation. After the Effective Time, Parent shall guarantee
the performance of the Surviving Corporation with respect to its obligations set
forth in the first sentence of this paragraph. For a period of six years after
the Effective Time, the Surviving Corporation will keep in effect in its
Certificate of Incorporation or Bylaws a provision providing for the
indemnification of the Indemnified Parties to the extent required under the
obligation described in the first sentence of this paragraph.

     The Merger Agreement also provides that either Parent or the Surviving
Corporation will maintain the Company's existing officers' and directors'
liability insurance ("D&O Insurance") for a period of not less than six years
after the Effective Time; provided that Parent may substitute therefor policies
of substantially equivalent coverage and amounts containing terms no less
favorable to such former directors or officers; provided, further, if the
existing D&O Insurance expires, is terminated or canceled during such period,
Parent or the Surviving Corporation will use all reasonable efforts to obtain
substantially similar D&O Insurance; provided, further, Parent shall not be
required to pay aggregate premiums for such insurance in excess of 200% of the
average of the aggregate premiums paid by the Company in 1997, 1998 and 1999
(through the date of the Merger Agreement) on an annualized basis for such
purpose (the "Average Premium"); and provided, further, that if Parent or the
Surviving Corporation is unable to obtain the amount of insurance required by
the provision described in this sentence for such aggregate premium, Parent or
the Surviving Corporation shall obtain as much insurance as can be obtained for
an annual premium not in excess of 200% of the Average Premium.

     Representations and Warranties. The Merger Agreement contains various
representations and warranties of the parties thereto, including representations
by the Company as to, among other things, corporate existence and good standing,
organization, capitalization, corporate authorization, financial statements,
public filings, conduct of business, employee benefit plans, intellectual
property, employment matters, compliance with applicable laws, tax matters,
litigation, environmental matters, material contracts, customers and suppliers,
brokers' fees, real property and assets, vote required to approve the Merger
Agreement, undisclosed liabilities, information in the Proxy Statement and the
absence of any material adverse effect on the Company since January 1, 1999. In
addition, Parent and the Purchaser represented as to, among other things,
corporate existence and good standing, corporate authorization and consents and
approvals. None of the parties' respective representations and warranties will
survive after the Effective Time.

     Access and Confidentiality. The Company has agreed to give Parent and its
authorized representatives access, during normal business hours, to the
properties, books, contracts, commitments, records and personnel of the Company
and its subsidiaries. Parent has agreed to hold in confidence all information
received by it pursuant to the terms and conditions of the Confidentiality
Agreement filed as Exhibit(c)(4) to the Schedule 14D-1 and incorporated herein
by reference.

     Termination. The Merger Agreement may be terminated and the Transactions
may be abandoned at any time before the Effective Time, whether before or after
stockholder approval:

          (i) By mutual written consent of Parent and the Board of Directors of
     the Company;

          (ii) By Parent if the Offer shall have expired or been terminated
     without any Shares being purchased thereunder by the Purchaser as a result
     of the failure to meet the conditions set forth in Annex A of the Merger
     Agreement;

          (iii) By either Parent or the Company if any court, arbitral tribunal,
     administrative agency or commission or other governmental or other
     regulatory authority or agency shall have issued an order, decree or ruling
     or taken any other action (which order, decree or ruling the parties to the
     Merger Agreement shall use their reasonable best efforts to lift), in each
     case permanently restraining, enjoining or otherwise prohibiting the
     Transactions;

                                       25
<PAGE>   28

          (iv) By Parent if, without any material breach by Parent or the
     Purchaser of its obligations under the Merger Agreement, the purchase of
     Shares pursuant to the Offer shall not have occurred on or before October
     31, 1999;

          (v) By the Company if, without any material breach by the Company of
     its obligations under the Merger Agreement, the purchase of Shares pursuant
     to the Offer shall not have occurred on or before October 31, 1999;

          (vi) By the Company (a) if, prior to the purchase of Shares pursuant
     to the Offer, there shall be a material breach of any of Parent or the
     Purchaser's representations, warranties or covenants in the Merger
     Agreement, which breach cannot be or has not been cured within ten days of
     the receipt of written notice thereof or (b) to allow the Company to enter
     into a definitive agreement to consummate a Superior Proposal (as defined
     below); provided, that it has complied with all provisions thereof; and
     provided further, that it furnishes a copy of the Superior Proposal,
     containing all of the terms and conditions thereof, to Parent at least two
     calendar days prior to terminating this Agreement pursuant to this clause;

          (vii) By Parent if, prior to the purchase of Shares pursuant to the
     Offer, the Company shall have breached in any material respect (without
     reference to any materiality qualification contained therein) any
     representation, warranty or covenant or other agreement contained in the
     Merger Agreement, which breach (a) would give rise to the failure of a
     condition set forth in paragraph (f) or (g) of Annex A of the Merger
     Agreement (which pertain to the representations and warranties of the
     Company set forth in the Merger Agreement being true and correct and the
     Company's performance of any obligation, or compliance with any agreement
     or covenant to be performed or complied with by it, under the Merger
     Agreement); and (b) cannot be or has not been cured within ten days of the
     receipt of written notice thereof;

          (viii) By Parent if (a) the Board of Directors of the Company shall
     withdraw, modify, or change its recommendation or approval in respect of
     the Merger Agreement or the Offer in a manner adverse to the Purchaser or
     (b) the Board of Directors of the Company shall have recommended any
     proposal other than by Parent or the Purchaser in respect of a Takeover
     Proposal; or

          (ix) By Parent if (a) the Company has exercised a right regarding a
     Takeover Proposal described under the second paragraph of "-- No
     Solicitation" above and, directly or indirectly (including through its
     representatives), shall continue discussions or negotiations with a third
     party for more than 20 business days after the date of receipt of such
     Takeover Proposal or (b) a Takeover Proposal shall have been publicly
     disclosed, commenced, proposed or communicated to the Company other than by
     Parent or the Purchaser, and the Board of Directors of the Company shall
     have not affirmatively rejected such Takeover Proposal within 20 business
     days after the earlier of receipt or the public disclosure of such Takeover
     Proposal.

     A "Superior Proposal" is a bona fide written Takeover Proposal submitted by
any person other than Parent or the Purchaser on an unsolicited basis that the
Board of Directors of the Company determines in good faith, based on the advice
of its financial advisor, represents a transaction that is more financially
favorable to the stockholders of the Company than the Offer and the Merger.

     Termination Fee and Expenses. If the Merger Agreement is terminated as
described above, written notice shall be given forthwith to the other party or
parties specifying the provision of the Merger Agreement pursuant to which such
termination is made, the Merger Agreement will become null and void, and there
shall be no liability on the part of Parent, the Purchaser or the Company,
except (i) as set forth in Section 6.5 of the Merger Agreement (pertaining to
confidentiality), the provisions described below in this paragraph, and Section
9.3 of the Merger Agreement (pertaining to expenses) and (ii) nothing in the
Merger Agreement shall relieve any party from liability for any material breach
of the Merger Agreement. If (i) the Company terminates the Merger Agreement
pursuant to the provision described in clause (vi)(b) of the preceding
paragraph, (ii) Parent terminates the Merger Agreement pursuant to the provision
described in clause (viii) of the preceding paragraph, or (iii) (A) Parent
terminates the Merger Agreement pursuant to the

                                       26
<PAGE>   29

provision described in clause (ii) (because the Minimum Condition has not been
satisfied), (vii) (and the breach giving rise to such right to terminate shall
have been willful or in bad faith) or (ix), each of the preceding paragraph, and
(B) in each case, the Company has consummated or entered into a definitive
agreement with respect to a Takeover Proposal within twelve months following the
date of such termination, then the Company shall pay to Parent, (A) in the case
of clause (i) or (ii) above, at the time of such termination, and, in the case
of clause (iii) above, upon the Company's consummation of or entry into a
definitive agreement regarding such Takeover Proposal, an amount equal to
$6,500,000 (which, in the case of a termination pursuant to the provision
described in clause (vii) of the preceding paragraph, shall constitute
liquidated damages with respect to any breach giving rise to a right to
terminate under the Merger Agreement) plus an amount (not to exceed $1,500,000)
equal to Parent's and the Purchaser's actual out-of-pocket expenses attributable
to the Offer, the Merger, the Merger Agreement and the consummation of the
Transactions.

     Fees and Expenses. Except as set forth in the provision described in the
preceding paragraph, fees, costs and expenses incurred in connection with the
Merger Agreement and the Transactions shall be paid by the party incurring such
fees, costs and expenses.

     Amendments and Modifications. Subject to applicable law, the Merger
Agreement may be amended, modified or supplemented by a written agreement of
Parent, the Purchaser and the Company, provided, that after the approval of the
Merger Agreement by the stockholders of the Company, no such amendment,
modification or supplement shall reduce or change the consideration to be
received by the Company's stockholders in the Merger.

THE STOCKHOLDER AGREEMENTS

     As a condition to Parent's willingness to enter into the Merger Agreement,
Parent and the Purchaser entered into Stockholder Agreements dated as of July
28, 1999 with each of AIP, which holds 4,239,470 Shares, and certain directors
and executive officers of the Company, who collectively hold 226,800 Shares.
Pursuant to its Stockholder Agreement, AIP has agreed, among other things, to
tender the Shares held by it in the Offer and granted the Purchaser an
irrevocable proxy to vote such Shares in connection with any meeting of the
stockholders of the Company in favor of the Merger and against any action that
would interfere with the Merger, including any proposal by a third party to
acquire the Company. Pursuant to his respective Stockholder Agreement, each
director and executive officer of the Company has agreed, among other things, to
tender the Shares held by him in the Offer. The foregoing obligations of AIP and
the directors and executive officers terminate upon the termination of the
Merger Agreement, including pursuant to a fiduciary out exercised by the Board
of Directors of the Company. The foregoing description of the Stockholder
Agreements does not purport to be complete and is qualified by reference to the
text of the Stockholder Agreements.

APPRAISAL RIGHTS

     No appraisal rights are available in connection with the Offer. However, if
the Merger is consummated, stockholders of the Company will have certain rights
under the Delaware Law to dissent and demand appraisal of, and to receive
payment in cash for the fair value of, their Shares. Such rights to dissent, if
the stockholder does not vote in favor of the Merger and complies with certain
statutory procedures, could lead to a judicial determination of the fair value
of the Shares (excluding any element of value arising from the accomplishment or
expectation of the Merger) required to be paid in cash to such dissenting
holders for their Shares. Such value could be less than, equal to, or more than
the Offer Price. In addition, such dissenting stockholders may be entitled to
receive payment of interest from the date of consummation of the Merger on the
amount determined to be the fair value of their Shares. In determining the fair
value of the Shares, a Delaware court would be required to take into account all
relevant factors. Accordingly, such determination could be based upon
considerations other than, or in addition to, the market value of the Shares,
including, among other things, asset values and earning capacity.

                                       27
<PAGE>   30

     If any holder of Shares who demands appraisal under the Delaware Law fails
to perfect, or effectively withdraws or loses his right to appraisal, as
provided in the Delaware Law, the Shares of such stockholder will be converted
into the Offer Price in accordance with the Merger Agreement.

     The foregoing discussion is not a complete statement of law pertaining to
appraisal rights under the Delaware Law and is qualified in its entirety by the
full text of Section 262 of the Delaware Law.

RULE 13E-3

     The SEC has adopted Rule 13e-3 under the Exchange Act, which is applicable
to certain "going private" transactions and that may under certain circumstances
be applicable to the Merger following the purchase of Shares pursuant to the
Offer in which the Purchaser seeks to acquire any remaining Shares. Rule 13e-3
should not be applicable to the Merger if the Merger is consummated within one
year after the expiration or termination of the Offer and the price paid in the
Merger is not less than the price per Share paid pursuant to the Offer. However,
in the event that the Purchaser is deemed to have acquired control of the
Company pursuant to the Offer and if the Merger is consummated more than one
year after completion of the Offer or an alternative acquisition transaction is
effected whereby stockholders of the Company receive consideration less than
that paid pursuant to the Offer, in either case at a time when the Shares are
still registered under the Exchange Act, the Purchaser may be required to comply
with Rule 13e-3 under the Exchange Act. If applicable, Rule 13e-3 would require,
among other things, that certain financial information concerning the Company
and certain information relating to the fairness of the Merger or such
alternative transaction and the consideration offered to minority stockholders
in the Merger or such alternative transaction, be filed with the SEC and
disclosed to stockholders prior to consummation of the Merger or such
alternative transaction. The purchase of a substantial number of Shares pursuant
to the Offer may result in the Company being able to terminate its Exchange Act
registration. See Section 7. If such registration were terminated, Rule 13e-3
would be inapplicable to any such future Merger or such alternative transaction.

14. DIVIDENDS AND DISTRIBUTIONS.

     The Merger Agreement provides that neither the Company nor any of its
subsidiaries will, among other things, from the date of the Merger Agreement
until the time Parent's designees shall constitute a majority of the Board of
Directors of the Company (i) declare, set aside pay or make provision for any
dividend or other distribution payable in cash, stock or property with respect
to its capital stock (other than as described in Section 6 of this Offer to
Purchase), (ii) issue, sell, pledge, dispose of or encumber any additional
shares of, or securities convertible into or exchangeable for, or options,
warrants, calls, commitments or rights of any kind to acquire (or stock
appreciation rights with respect to), any shares of capital stock of any class
of the Company or its subsidiaries, other than Shares reserved for issuance on
the date of the Merger Agreement pursuant to the exercise of Options outstanding
on the date of the Merger Agreement, (iii) enter into any agreement or
understanding with respect to the voting of any of its capital stock or the
capital stock of any subsidiary or (iv) redeem, purchase or otherwise acquire,
directly or indirectly, any of its capital stock.

15. CERTAIN CONDITIONS TO THE PURCHASER'S OBLIGATIONS.

     Notwithstanding any other provisions of the Offer, and in addition to (and
not in limitation of) the Purchaser's rights to extend and amend the Offer at
any time in its sole discretion (subject to the provisions of the Merger
Agreement), the Purchaser shall not be required to accept for payment or,
subject to any applicable rules and regulations of the SEC, including Rule
14e-l(c) under the Exchange Act (relating to the Purchaser's obligation to pay
for or return tendered Shares promptly after termination or withdrawal of the
Offer), pay for, and may delay the acceptance for payment of or, subject to the
restriction referred to above, the payment for, any tendered Shares, and may
terminate or amend the Offer as to any Shares not then paid for, if any
applicable waiting period under the HSR Act has not expired or been terminated,
the Minimum Condition has not been satisfied, or at any time on or after the
date of the Merger Agreement and before the

                                       28
<PAGE>   31

time of acceptance for payment for any such Shares, any of the following events
shall have occurred and be continuing:

          (i) there shall be threatened (in writing) or pending any suit, action
     or proceeding by any court, arbitral tribunal, administrative agency or
     commission or other governmental or other regulatory authority or agency
     against the Purchaser, Parent, the Company or any subsidiary of the Company
     (a) challenging the acquisition by Parent or the Purchaser of any Shares
     under the Offer, seeking to restrain or prohibit the making or consummation
     of the Offer or the Merger or the performance of any of the other
     transactions contemplated by the Merger Agreement or the Stockholder
     Agreements, (b) seeking to impose material limitations on the ability of
     the Purchaser, or render the Purchaser unable, to accept for payment, pay
     for or purchase some or all of the Shares pursuant to the Offer and the
     Merger, (c) seeking to impose material limitations on the ability of the
     Purchaser or Parent effectively to acquire, hold or exercise full rights of
     ownership of the Shares, including, without limitation, the right to vote
     the Shares purchased by it on all matters properly presented to the
     Company's stockholders, (d) seeking to prohibit or restrict the ownership
     or operation by Parent or the Purchaser (or any of their respective
     affiliates or subsidiaries) of any portion of its or the Company's business

     subsidiaries or of Parent and its subsidiaries or compel Parent or the
     Purchaser (or any of their respective affiliates or subsidiaries) to
     dispose of or hold separate any portion of its or the Company's business or
     assets which is material to the business of the Company and its
     subsidiaries or of Parent and its subsidiaries; (e) seeking to impose any
     material limitations on the ability of Parent or the Purchaser or any of
     their respective affiliates or subsidiaries effectively to control in any
     material respect the business and operations of the Company and its
     subsidiaries, or (f) which otherwise is reasonably likely to have a Company
     Material Adverse Effect (as defined in the Merger Agreement);

          (ii) there shall be any statute, rule, regulation, judgment, order or
     injunction enacted, entered, enforced, promulgated, or deemed applicable,
     pursuant to an authoritative interpretation by or on behalf of any court,
     arbitral tribunal, administrative agency or commission or other
     governmental or other regulatory authority or agency, to the Offer or the
     Merger, or any other action shall be taken by any court, arbitral tribunal,
     administrative agency or commission or other governmental or other
     regulatory authority or agency, other than the application to the Offer or
     the Merger of applicable waiting periods under the HSR Act, that is
     reasonably likely to result, directly or indirectly, in any of the
     consequences referred to in clauses (a) through (f) of paragraph (i) above;

          (iii) there shall have occurred (a) a declaration of a banking
     moratorium or any suspension of payments in respect of banks in the United
     States (whether or not mandatory), (b) any limitation (whether or not

     securities exchange, over-the-counter market or The Nasdaq Stock Market for
     a period in excess of 24 hours (excluding suspensions or limitations
     resulting solely from physical damage or interference with such exchanges
     not related to market conditions), or (e) in the case of any of the
     foregoing existing at the time of the commencement of the Offer, a material
     acceleration or worsening thereof;

          (iv) since March 31, 1999, there shall have occurred any change that
     constitutes a Company Material Adverse Effect (or there shall have been any
     development that is reasonably likely to result in a Company Material
     Adverse Effect);

          (v) (a) the Board of Directors or any committee thereof shall have
     withdrawn or modified in a manner adverse to Parent or the Purchaser its
     approval or recommendation of the Offer, the Merger or the Merger
     Agreement, or approved or recommended any Takeover Proposal or (b) the
     Company shall have entered into any agreement in principle or definitive
     agreement with respect to any Takeover

                                       29
<PAGE>   32

     Proposal or shall have exercised its rights in accordance with Section
     5.1(b) of the Merger Agreement (pertaining to actions taken to fulfill the
     directors' fiduciary duties) with respect to a Takeover Proposal;

          (vi) any of the representations and warranties of the Company set
     forth in the Merger Agreement shall not be true and correct (without
     reference to any materiality qualification contained therein) in each case
     (a) as of the date referred to in any representation or warranty which
     addresses matters as of a particular date, or (b) as to all other
     representations and warranties, as of the date of the Merger Agreement and
     as of the scheduled expiration of the Offer except for any breach that
     individually or in the aggregate, together with all other breaches, could
     not reasonably be expected to have a Company Material Adverse Effect;

          (vii) the Company shall have failed to perform in any material respect
     any obligation, or to comply with any agreement or covenant to be performed
     or complied with by it, under the Merger Agreement; or

          (viii) the Merger Agreement shall have been terminated in accordance
     with its terms.

     The foregoing conditions are for the sole benefit of Parent and the
Purchaser, may be asserted by Parent or the Purchaser regardless of the
circumstances giving rise to such condition (including any action or inaction by
Parent or the Purchaser) and may be waived by Parent or the Purchaser in whole
or in part at any time and from time to time in the sole discretion of Parent or
the Purchaser, subject in each case to the terms of the Merger Agreement. The
failure by Parent or the Purchaser at any time to exercise any of the foregoing
rights shall not be deemed a waiver of any such right and each such right shall
be deemed an ongoing right which may be asserted at any time and from time to
time.

     Should the Offer be terminated pursuant to the foregoing provisions, all
tendered Shares not already accepted for payment shall be returned forthwith by
the Depositary to the tendering stockholders.

16. CERTAIN LEGAL MATTERS.

     Based on a review of publicly available filings made by the Company with
the SEC and other publicly available information concerning the Company, neither
the Purchaser nor Parent is aware of any license or regulatory permit that
appears to be material to the business of the Company and its subsidiaries,
taken as a whole, that might be adversely affected by the Purchaser's
acquisition of Shares as contemplated herein or of any approval or other action,
except as otherwise described in this Section 16, by any governmental,
administrative or regulatory agency or authority, domestic, foreign or
supernational, that would be required for the acquisition or ownership of Shares
by the Purchaser as contemplated herein. Should any such approval or other
action be required, the Purchaser and Parent currently contemplate that such
approval or other action will be sought, except as described below under "State
Takeover Laws." While, except as otherwise expressly described in this Section
16, the Purchaser does not presently intend to delay the acceptance for payment
of or payment for Shares tendered pursuant to the Offer pending the outcome of
any such matter, there can be no assurance that any such approval or other
action, if needed, would be obtained or would be obtained without substantial
conditions or that failure to obtain any such approval or other action would not
result in consequences adverse to the Company's business or that certain parts
of the Company's business would not have to be disposed of if such approvals
were not obtained or such other actions were not taken in order to obtain any
such approval or other action. If certain types of adverse action are taken with
respect to the matters discussed below, the Purchaser could, subject to the
terms and conditions of the Merger Agreement, decline to accept for payment or
pay for any Shares tendered. See Section 15 for a discussion of certain
conditions to the Offer.

     State Takeover Laws. The Company is incorporated under the laws of
Delaware. No Delaware takeover statute or similar statute or regulation,
including, without limitation, Section 203 of the Delaware Law (as to which the
Company has taken all action to render inapplicable to the transactions
contemplated by the Merger Agreement), imposes restrictions materially and
adversely affecting (or materially delaying) the consummation of the Offer or
the Merger or would, as a result of the Offer, the Merger, the transactions
contemplated by the Merger Agreement or the acquisition of securities of the
Company by Parent or the Purchaser (i) restrict or impair the ability of Parent
to vote, or otherwise to exercise the rights of a stockholder with respect to,

                                       30
<PAGE>   33

securities of the Company or the Surviving Corporation that may be acquired or
controlled by Parent or (ii) entitle any stockholder to acquire securities of
the Company or the Surviving Corporation on a basis not available to Parent.

     A number of states throughout the United States have enacted takeover
statutes that purport, in varying degrees, to be applicable to attempts to
acquire securities of corporations that are incorporated or have assets,
stockholders, executive offices or places of business in such states. In Edgar
v. MITE Corp., the Supreme Court of the United States held that the Illinois
Business Takeover Act, which involved state securities laws that made the
takeover of certain corporations more difficult, imposed a substantial burden on
interstate commerce and therefore was unconstitutional. In CTS Corp. v. Dynamics
Corp. of America, however, the Supreme Court of the United States held that a
state may, as a matter of corporate law, and, in particular, those laws
concerning corporate governance, constitutionally disqualify a potential
acquiror from voting on the affairs of a target corporation without prior
approval of the remaining stockholders, provided that such laws were applicable
only to corporations incorporated in the state of enactment with a substantial
number of stockholders residing in that state. Subsequently, a number of federal
courts ruled that various state takeover statutes were unconstitutional insofar
as they apply to corporations incorporated outside the state of enactment.

     Based on information supplied by the Company and its own review, Caradon
plc, Parent and the Purchaser do not believe that any other state takeover
statutes purport to apply to the Offer or the Merger, with the possible
exception of the Ohio tender offer statute (as to which the Purchaser intends to
make the required filings). Except as described in the previous sentence,
neither Caradon plc, Parent nor the Purchaser has currently complied with any
state takeover statute or regulation. The Purchaser reserves the right to
challenge the applicability or validity of any state law purportedly applicable
to the Offer or the Merger and nothing in this Offer to Purchase or any action
taken in connection with the Offer or the Merger is intended as a waiver of such
right. If it is asserted that any state takeover statute is applicable to the
Offer or the Merger and an appropriate court does not determine that it is
inapplicable or invalid as applied to the Offer or the Merger, the Purchaser
might be required to file certain information with, or to receive approvals
from, the relevant state authorities, and the Purchaser might be unable to
accept for payment or pay for Shares tendered pursuant to the Offer, or be
delayed in consummating the Offer or the Merger. In such case, the Purchaser may
not be obligated to accept for payment or pay for any Shares tendered pursuant
to the Offer. See Section 15.

     Antitrust Laws. Under the provisions of the HSR Act applicable to the
Offer, the acquisition of Shares under the Offer may be consummated following
the expiration of a 15-day waiting period following the filing by Parent of a
Premerger Notification and Report Form with respect to the Offer, unless Parent
receives a request for additional information or documentary material from the
Department of Justice, Antitrust Division (the "Antitrust Division") or the
Federal Trade Commission ("FTC") or unless early termination of the waiting
period is granted. Parent expects to make such a filing as soon as practicable
following the date of this Offer to Purchase. If, within the initial 15-day
waiting period, either the Antitrust Division or the FTC requests additional
information or documentary material concerning the Offer, then the waiting
period will be extended through the tenth day after the date of substantial
compliance by all parties receiving such requests. Complying with a request for
additional information or documentary material can take a significant amount of
time.

     The Antitrust Division and the FTC frequently scrutinize the legality under
the antitrust laws of transactions such as the Purchaser's proposed acquisition
of the Company. At any time before or after the Purchaser's acquisition of
Shares pursuant to the Offer, the Antitrust Division or the FTC could take such
action under the antitrust laws as it deems necessary or desirable in the public
interest, including seeking to enjoin the purchase of Shares pursuant to the
Offer or the consummation of the Merger, or seeking the divestiture of Shares
acquired by the Purchaser or the divestiture of substantial assets of the
Company or its subsidiaries or Parent or its subsidiaries. Private parties may
also bring legal action under the antitrust laws under certain circumstances.
There can be no assurance that a challenge to the Offer, the consummation of the
Merger or the purchase of the Shares on antitrust grounds will not be made, or,
if such a challenge is made, of the result thereof.
                                       31
<PAGE>   34

     If any applicable waiting period under the HSR Act applicable to the Offer
has not expired or been terminated prior to the Expiration Date, the Purchaser
will not be obligated to proceed with the Offer or the purchase of any Shares
not already purchased pursuant to the Offer. See Section 15.

     At any time before or after the Purchaser's purchase of Shares pursuant to
the Offer, an antitrust enforcement agency in jurisdictions other than the
United States could take such action under the applicable antitrust laws, if
any, as it deems necessary or desirable in the public interest. Private parties
may also be able to bring legal action under such antitrust laws under certain
circumstances. There can be no assurance that a challenge to the Offer on such
antitrust grounds will not be made or, if such a challenge is made, of the
results thereof.

     Exon-Florio. Under Section 721 of Title VII of the United States Defense
Production Act of 1950, as amended by Section 5021 of the Omnibus Trade and
Competitiveness Act of 1988 ("Exon-Florio"), the President of the United States
is authorized to prohibit or suspend acquisitions, mergers or takeovers by
foreign persons of persons engaged in interstate commerce in the United States
if the President determines, after investigation, that such foreign persons in
exercising control of such acquired persons might take action that threatens to
impair the national security of the United States and that other provisions of
existing law do not provide adequate authority to protect national security.
Pursuant to Exon-Florio, notice of an acquisition by a foreign person may be
made to the Committee on Foreign Investment in the United States ("CFIUS"),
which is comprised of representatives of the Departments of the Treasury, State,
Commerce, Defense and Justice, the Office of Management and Budget, the United
States Trade Representative's Office and the Council of Economic Advisors and
which has been selected by the President to administer Exon-Florio, either
voluntarily by the parties to such proposed acquisition, merger or takeover or
by any member of CFIUS.

     A determination that an investigation is called for must be made within 30
days after notification of a proposed acquisition, merger or takeover is first
filed with CFIUS. Any such investigation must be completed within 45 days of
such determination. Any decision by the President to take action must be
announced within 15 days of the completion of the investigation. Although
Exon-Florio does not require the filing of a notification, nor does it prohibit
the consummation of an acquisition, merger or takeover if notification is not
made, such an acquisition, merger or takeover thereafter remains indefinitely
subject to divestment should the President subsequently determine that the
national security of the United States has been threatened or impaired. Caradon
plc, Parent and the Purchaser do not believe that the Offer or the Merger
threatens to impair the national security of the United States and do not intend
to notify CFIUS of the proposed transaction.

17. FEES AND EXPENSES.

     KPMG Corporate Finance has been retained as a financial advisor to Parent
and will be paid an aggregate fee of between $1.8 million and $1.9 million if
the acquisition by Parent of the Company is completed or a time and effort fee
of between $30,000 and $40,000 if the acquisition is not completed. KPMG will
also be reimbursed for its out-of-pocket expenses (including legal fees) and
will be indemnified in connection with certain liabilities in connection with
its engagement.

     Parent has retained D. F. King & Co., Inc. as Information Agent and
ChaseMellon Shareholder Services, L.L.C. as Depositary in connection with the
Offer. The Information Agent and the Depositary will receive reasonable and
customary compensation for their services hereunder and reimbursement for their
reasonable out-of-pocket expenses. The Depositary will also be indemnified by
Parent against certain liabilities in connection with the Offer.

     Neither Caradon plc, the Purchaser nor Parent, nor any officer, director,
stockholder, agent or other representative of the Purchaser or Parent, will pay
any fees or commissions to any broker, dealer or other person (other than the
Information Agent) for soliciting tenders of Shares pursuant to the Offer.
Brokers, dealers, commercial banks and trust companies and other nominees will,
upon request, be reimbursed by the Purchaser for customary mailing and handling
expenses incurred by them in forwarding materials to their customers.

18. MISCELLANEOUS.

     The Offer is not being made to, nor will tenders be accepted from or on
behalf of, holders of Shares residing in any jurisdiction in which the making or
acceptance thereof would not be in compliance with the securities, blue sky or
other laws of such jurisdiction. In any jurisdiction where the securities, blue
sky or other laws require the Offer to be made by a licensed broker or dealer,
the Offer shall be deemed to be made on behalf of the Purchaser by one or more
registered brokers or dealers licensed under the laws of such jurisdiction.

     NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR MAKE ANY
REPRESENTATION ON BEHALF OF CARADON PLC, PARENT OR THE PURCHASER OTHER THAN AS
CONTAINED IN THIS OFFER TO PURCHASE OR IN THE LETTER OF TRANSMITTAL AND, IF ANY
SUCH INFORMATION OR REPRESENTATION IS GIVEN OR MADE, IT SHOULD NOT BE RELIED
UPON AS HAVING BEEN AUTHORIZED BY CARADON PLC, PARENT OR THE PURCHASER.

     Caradon plc, Parent and the Purchaser have filed with the SEC the Schedule
14D-1, pursuant to Section 14(d)(1) of the Exchange Act and Rule 14d-3 issued
thereunder, furnishing certain information with respect to the Offer. The
Schedule 14D-1 and any amendments thereto, including exhibits, may be examined

              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

     The undersigned hereby tenders to E Acqco Inc. (the "Purchaser"), a
Delaware corporation and an indirect wholly owned subsidiary of Caradon Inc., a
Delaware corporation ("Parent"), the above-described shares of Common Stock,
$.01 par value ("Shares"), of Easco, Inc., a Delaware corporation (the
"Company"), pursuant to the Purchaser's offer to purchase all of the outstanding
Shares at a purchase price of $15.20 per Share, net to the seller in cash,
without interest, all upon the terms and subject to the conditions set forth in
the offer to purchase dated August 3, 1999 (the "Offer to Purchase"), receipt of
which is hereby acknowledged, and in this Letter of Transmittal (which, together
with any amendments or supplements thereto, constitute the "Offer"). The Offer
is being made in connection with the Agreement and Plan of Merger, dated as of
July 28, 1999 (the "Merger Agreement"), among Parent, the Purchaser and the
Company.

     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of any such extension
or amendment), (i) the Purchaser will accept for payment and pay for, as
promptly as practicable after the later of the Expiration Date or the
satisfaction or waiver of all conditions to the Offer described in Section 15 of
the Offer to Purchase, all Shares validly tendered herewith prior to the
Expiration Date and not properly withdrawn in accordance with the terms of the
Offer, and (ii) the undersigned hereby sells, assigns and transfers to, or upon
the order of, the Purchaser all right, title and interest in and to all the
Shares that are being tendered hereby and any and all non-cash dividends,
distributions (including, without limitation, distribution of additional Shares)
or rights declared, paid or distributed in respect of such Shares on or after
July 28, 1999 (collectively, "Distributions"), and irrevocably constitutes and
appoints the Depositary the true and lawful agent and attorney-in-fact of the
undersigned with respect to such Shares and all Distributions, with full power
of substitution (such power of attorney being deemed to be an irrevocable power
coupled with an interest), to (a) deliver such Share Certificates and all
Distributions, or transfer ownership of such Shares and all Distributions on the
account books maintained by the Book-Entry Transfer Facility, together, in any
such case, with all accompanying evidences of transfer and authenticity to, or
upon the order of, the Purchaser, (b) present such Shares and all Distributions
for transfer on the Company's books and (c) receive all benefits and otherwise
exercise all rights of beneficial ownership of such Shares and all
Distributions, all in accordance with the terms of the Offer.

     By executing this Letter of Transmittal, the undersigned irrevocably
appoints Robert B. Leckie and Pat M. Simmons as proxies of the undersigned, each
with full power of substitution, to the full extent of the undersigned's rights
with respect to the Shares tendered by the undersigned and accepted for payment
by the Purchaser (and any and all Distributions). All such proxies shall be
considered coupled with an interest in the tendered Shares. This appointment
will be effective if, when, and only to the extent that, the Purchaser accepts
such Shares for payment pursuant to the Offer. Upon such acceptance for payment,
all prior powers of attorney and proxies given by the undersigned with respect
to such Shares (and such other Shares and securities) will, without further
action, be revoked, and no subsequent proxies may be given nor any subsequent
written consent executed by the undersigned (and, if given or executed, will not
be deemed to be effective) with respect thereto. The designees of the Purchaser
named above will, with respect to the Shares and other securities for which the
appointment is effective, be empowered to exercise all voting and other rights
of the undersigned as they in their sole discretion may deem proper at any
annual or special meeting of the stockholders of the Company or any adjournment
or postponement thereof, by written consent in lieu of any such meeting or
otherwise, and the Purchaser reserves the right to require that, in order for
Shares or other securities to be deemed validly tendered, immediately upon the
Purchaser's acceptance for payment of such Shares, the Purchaser must be able to
exercise full voting rights with respect to such Shares.

     The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, sell, assign and transfer the tendered
Shares (and all Distributions) and, when the same are accepted for payment by
the Purchaser, the Purchaser will acquire good, marketable and unencumbered
title thereto, free and clear of all liens, restrictions, charges and
encumbrances, and that the same will not be subject to any adverse claim. The
undersigned will, upon request, execute and deliver any additional documents
deemed by the Depositary or the Purchaser to be necessary or desirable to
complete the sale, assignment and transfer of the tendered Shares (and all
Distributions). In addition, the undersigned shall promptly remit and transfer
to the Depositary for the account of the Purchaser any and all Distributions in
respect of the Shares tendered hereby, accompanied by appropriate documentation
of transfer, and, pending such
                                        3
<PAGE>   4

remittance and transfer or appropriate assurance thereof, the Purchaser shall be
entitled to all rights and privileges as owner of each such Distribution and may
withhold the entire purchase price of the tendered Shares or deduct from such
purchase price, the amount or value of such Distribution as determined by the
Purchaser in its sole discretion.

     All authority conferred or agreed to be conferred pursuant to this Letter
of Transmittal shall be binding upon the successors, assigns, heirs, executors,
administrators, trustees in bankruptcy and legal representatives of the
undersigned and shall not be affected by, and shall survive, the death or
incapacity of the undersigned. Except as stated in the Offer to Purchase, this
tender is irrevocable.

     The undersigned understands that the valid tender of Shares pursuant to any
of the procedures described in Section 2 of the Offer to Purchase and in the
Instructions hereto will constitute a binding agreement between the undersigned
and the Purchaser upon the terms and subject to the conditions of the Offer,
including, without limitation, the undersigned's representation and warranty
that the undersigned owns the Shares being tendered.

     Unless otherwise indicated herein under "Special Payment Instructions,"
please issue the check for the purchase price and/or return any certificates for
Shares not tendered or accepted for payment in the name(s) of the registered
holder(s) appearing under "Description of Shares Tendered." Similarly, unless

Special Payment Instructions are completed, please issue the check for the

accepted for payment (and any accompanying documents, as appropriate) in the

Please credit any Shares tendered herewith by book-entry transfer that are not
accepted for payment by crediting the account at the Book-Entry Transfer

pursuant to the Special Payment Instructions to transfer any Shares from the
name of the registered holder(s) thereof if the Purchaser does not accept for
payment any of the Shares so tendered.

                                  INSTRUCTIONS

             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER

     1. Guarantee of Signatures. No signature guarantee is required on this
Letter of Transmittal if (i) this Letter of Transmittal is signed by the
registered holder of Shares (which, for purposes of this Section, includes any
participant in the Book-Entry Transfer Facility's system whose name appears on a
security position listing as the owner of the Shares) tendered herewith and such
registered holder has not completed either the box entitled "Special Delivery
Instructions" or the box entitled "Special Payment Instructions" on this Letter
of Transmittal or (ii) such Shares are tendered for the account of a firm that
is a participant in the Security Transfer Agents Medallion Program, the New York
Stock Exchange Medallion Signature Guarantee Program or the Stock Exchange
Medallion Program (each, an "Eligible Institution"). In all other cases, all
signatures on this Letter of Transmittal must be guaranteed by an Eligible
Institution. See Instruction 5. If the certificates for Shares are registered in
the name of a person other than the signer of this Letter of Transmittal, or if
payment is to be made or certificates for Shares not tendered or not accepted
for payment are to be issued to a person other than the registered holder of the
certificates surrendered, the tendered certificates must be endorsed or
accompanied by appropriate stock powers, in either case signed exactly as the
name or names of the registered holders or owners appear on the certificates,
with the signatures on the certificates or stock powers guaranteed as described
above. See Instruction 5.

     2. Requirements of Tender. This Letter of Transmittal is to be completed by
stockholders either if Share Certificates are to be forwarded herewith or,
unless an Agent's Message (as defined below) is utilized, if delivery of Shares
is to be made pursuant to the procedures for book-entry transfer set forth in
Section 2 of the Offer to Purchase. For a stockholder validly to tender Shares
pursuant to the Offer, either (i) a properly completed and duly executed Letter
of Transmittal (or facsimile thereof), together with any required signature
guarantees, or, in the case of a book-entry transfer, an Agent's Message, and
any other documents required by the Letter of Transmittal, must be received by
the Depositary at one of its addresses set forth herein prior to the Expiration
Date and either (a) certificates for tendered Shares must be received by the
Depositary at one of such addresses prior to the Expiration Date or (b) Shares
must be delivered pursuant to the procedures for book-entry transfer set forth
herein and a Book-Entry Confirmation (as defined in the Offer to Purchase) must
be received by the Depositary prior to the Expiration Date, or (ii) the
tendering stockholder must comply with the guaranteed delivery procedures set
forth below and in Section 2 of the Offer to Purchase.

     The term "Agent's Message" means a message transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that the Book-Entry Transfer Facility has
received an express acknowledgment from the participant in the Book-Entry
Transfer Facility tendering the Shares that such participant has received and
agrees to be bound by the terms of this Letter of Transmittal and that the
Purchaser may enforce such agreement against the participant.

     If Share Certificates are forwarded to the Depositary in multiple
deliveries, a properly completed and duly executed Letter of Transmittal must
accompany each such delivery. If a stockholder desires to tender Shares pursuant
to the Offer and such stockholder's Share Certificates are not immediately
available or the procedure for book-entry transfer cannot be completed on a
timely basis or time will not permit all required documents to reach the
Depositary prior to the Expiration Date, such stockholder's tender may be
effected if all the following conditions are met: (i) such tender is made by or
through an Eligible Institution; (ii) a properly completed and duly executed
Notice of Guaranteed Delivery substantially in the form provided by the
Purchaser is received by the Depositary, as provided in Section 2 of the Offer
to Purchase, prior to the Expiration Date; and (iii) the Share Certificates for
all tendered Shares, in proper form for transfer (or a Book-Entry Confirmation
with respect to such Shares), together with a properly completed and duly
executed Letter of Transmittal (or facsimile thereof), with any required
signature guarantees, or, in the case of a book-entry transfer, an Agent's
Message, and any other documents required by this Letter of Transmittal, are
received by the Depositary within three trading days after the date of execution
of the Notice of Guaranteed Delivery as provided in Section 2 of the Offer to
Purchase. A "trading day," for purposes of the preceding sentence, is any day on
which The Nasdaq Stock Market is open for business.

     THE METHOD OF DELIVERY OF SHARES, THIS LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE BOOK-ENTRY TRANSFER FACILITY,
IS AT THE ELECTION AND RISK OF THE TENDERING STOCKHOLDER. SHARES WILL BE DEEMED
DELIVERED ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY. IF DELIVERY IS BY MAIL,
REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED.
IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.
                                        6
<PAGE>   7

     No alternative, conditional or contingent tenders will be accepted and no
fractional Shares will be purchased. All tendering stockholders, by execution of
this Letter of Transmittal (or facsimile thereof), waive any right to receive
any notice of the acceptance of their Shares for payment.

     3. Inadequate Space. If the space provided herein is inadequate, the
certificate numbers and/or the number of Shares and any other required
information should be listed on a separate schedule attached hereto.

     4. Partial Tenders. (Applicable to Certificate Stockholders Only.) If fewer
than all the Share Certificates submitted are to be tendered, fill in the number
of Shares that are to be tendered in the box entitled "Number of Shares
Tendered." In any such case, new Share Certificates for the remainder of the
Shares that were evidenced by the old Share Certificates will be sent to the
registered holder, unless otherwise provided in the appropriate box on this
Letter of Transmittal, as soon as practicable after the acceptance for payment
of, and payment for, the Shares tendered herewith. All Shares represented by
Share Certificates delivered to the Depositary will be deemed to have been
tendered unless otherwise indicated.

     5. Signatures on Letter of Transmittal, Stock Powers and Endorsements. If
this Letter of Transmittal is signed by the registered holder(s) of the Shares
tendered hereby, the signature(s) must correspond with the name(s) as written on
the face of the Share Certificate(s) without any change whatsoever.

     If any of the Shares tendered hereby are owned of record by two or more
joint owners, all such owners must sign this Letter of Transmittal.

     If any tendered Shares are registered in different names on several Share
Certificates, it will be necessary to complete, sign and submit as many separate
Letters of Transmittal as there are different registrations of Share
Certificates.

     If this Letter of Transmittal is signed by the registered holder(s) of the
Shares listed and transmitted hereby, no endorsements of Share Certificates or
separate stock powers are required unless payment is to be made to, or Share
Certificates for Shares not tendered or accepted for payment are to be issued
to, a person other than the registered holder(s). Signatures on such Share
Certificates and stock powers must be guaranteed by an Eligible Institution.

     If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the Share Certificates listed, the Share Certificates
must be endorsed or accompanied by appropriate stock powers, in either case
signed exactly as the name or names of the registered holder(s) appear on the
Share Certificates. Signatures on such Share Certificates and stock powers must
be guaranteed by an Eligible Institution.

     If this Letter of Transmittal or any Share Certificate or stock power is
signed by a trustee, executor, administrator, guardian, attorney-in-fact,
officer of a corporation or other person acting in a fiduciary or representative
capacity, such person should so indicate when signing, and proper evidence
satisfactory to the Purchaser of such person's authority so to act must be
submitted.

     6. Stock Transfer Taxes. Except as provided in this Instruction 6, the
Purchaser will pay stock transfer taxes with respect to the transfer and sale of
Shares to the Purchaser or its assignee pursuant to the Offer. If, however,
payment of the purchase price is to be made to, or if certificates for Shares
not tendered or accepted for payment are to be registered in the name of, any
person(s) other than the registered holder(s), or if tendered certificates are
registered in the name of any person other than the person(s) signing this
Letter of Transmittal, the amount of any stock transfer taxes (whether imposed
on the registered holder(s) or such person) payable on account of the transfer
to such person will be deducted from the purchase price unless satisfactory
evidence of the payment of such taxes or exemption therefrom is submitted.

     Except as provided in this Instruction 6, it will not be necessary for
transfer tax stamps to be affixed to the Share Certificates listed in this
Letter of Transmittal.

     7. Special Payment and Delivery Instructions. If a check is to be issued in
the name of and/or certificates for Shares not tendered or not accepted for
payment are to be returned to, a person other than the signer of this Letter of
Transmittal or if a check is to be sent and/or such Share Certificates are to be
returned to a person other than the signer of this Letter of Transmittal or to
an address other than that shown above, the appropriate boxes on this Letter of
Transmittal must be completed.

     8. Waiver of Conditions. The Purchaser reserves the absolute right in its
sole discretion to waive any of the specified conditions of the Offer, in whole
or in part, in the case of any Shares tendered.
                                        7

     9. 31% Backup Withholding; Substitute Form W-9. In order to avoid "backup
withholding" of federal income tax on payments of cash pursuant to the Offer, a
stockholder surrendering Shares in the Offer must provide the Depositary with
such stockholder's correct taxpayer identification number ("TIN") on a
Substitute Form W-9 and certify under penalty of perjury that such TIN is
correct and that such stockholder is not subject to backup withholding. Certain
stockholders (including, among others, all corporations and certain foreign
individuals and entities) are not subject to backup withholding. If a
stockholder does not provide its correct TIN or fails to provide the
certifications described above, the Internal Revenue Service ("IRS") may impose
a penalty on such stockholder and payment of cash to such stockholder pursuant
to the Offer may be subject to backup withholding of 31%. All stockholders
surrendering Shares pursuant to the Offer should complete and sign the main
signature form and the Substitute Form W-9 included as part of the Letter of
Transmittal to provide the information and certification necessary to avoid
backup withholding (unless an applicable exemption exists and is proved in a
manner satisfactory to the Purchaser and the Depositary). Noncorporate foreign
stockholders should complete and sign the main signature form and a Form W-8,
Certificate of Foreign Status, a copy of which may be obtained from the
Depositary, in order to avoid backup withholding. See the enclosed "Guidelines
for Certification of Taxpayer Identification Number on Substitute Form W-9" for
more instructions.

     If backup withholding applies to a stockholder, the Depositary is required
to withhold 31% from payments to such stockholder. Backup withholding is not an
additional tax. Rather, the amount of the backup withholding can be credited
against the federal income tax liability of the person subject to the backup
withholding, provided that the required information is given to the IRS. If
backup withholding results in an overpayment of tax, a refund can be obtained by
the stockholder upon filing an income tax return.

     The box in Part 3 of the Substitute Form W-9 may be checked if the
tendering stockholder has not been issued a TIN and has applied for a TIN or
intends to apply for a TIN in the near future. If the box in Part 3 is checked,
the stockholder or other payee must also complete the Certificate of Awaiting
Taxpayer Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part 3 is checked and the Certificate of
Awaiting Taxpayer Identification Number is completed, the Depositary will
withhold 31% of all payments made prior to the time a properly certified TIN is
provided to the Depositary. However, such amounts will be refunded to such
stockholder if a TIN is provided to the Depositary within 60 days.

     The stockholder is required to give the Depositary the TIN (e.g., social
security number or employer identification number) of the record owner of the
Shares or of the last transferee appearing on the transfers attached to, or
endorsed on, the Shares. If the Shares are in more than one name or are not in
the name of the actual owner, consult the enclosed "Guidelines for Certification
of Taxpayer Identification Number on Substitute Form W-9" for additional
guidance on which TIN to report.

     10. Requests for Assistance or Additional Copies. Requests for additional
copies of the Offer to Purchase, this Letter of Transmittal, the Notice of
Guaranteed Delivery and the Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 and questions or requests for
assistance may be directed to the Information Agent at its address set forth
below.

     11. Lost, Destroyed or Stolen Certificates. If any Share Certificate has
been lost, destroyed or stolen, the stockholder should promptly notify the
Company's stock transfer agent, ChaseMellon Shareholder Services, L.L.C., at
(800) 851-9677. The stockholder will then be instructed as to the steps that
must be taken in order to replace the Share Certificate. This Letter of
Transmittal and related documents cannot be processed until the procedures for
replacing lost or destroyed certificates have been followed.

     IMPORTANT: THIS LETTER OF TRANSMITTAL (OR FACSIMILE HEREOF), PROPERLY
COMPLETED AND DULY EXECUTED, TOGETHER WITH ANY REQUIRED SIGNATURE GUARANTEES,
OR, IN THE CASE OF A BOOK-ENTRY TRANSFER, AN AGENT'S MESSAGE, AND ALL OTHER
REQUIRED DOCUMENTS, MUST BE RECEIVED BY THE DEPOSITARY ON OR PRIOR TO THE
EXPIRATION DATE AND EITHER SHARE CERTIFICATES FOR TENDERED SHARES MUST BE
RECEIVED BY THE DEPOSITARY OR SHARES MUST BE DELIVERED PURSUANT TO THE
PROCEDURES FOR BOOK-ENTRY TRANSFER, OR THE NOTICE OF GUARANTEED DELIVERY MUST BE
RECEIVED BY THE DEPOSITARY, IN EACH CASE ON OR PRIOR TO THE EXPIRATION DATE, OR
THE TENDERING STOCKHOLDER MUST COMPLY WITH THE PROCEDURES FOR GUARANTEED
DELIVERY.

     The Offer is being made pursuant to the Agreement and Plan of Merger dated
as of July 28, 1999 (the "Merger Agreement") among Parent, the Purchaser and the
Company. Following the satisfaction or waiver of certain conditions, including
approval by stockholders of the Company if such approval is required by
applicable law, the Purchaser will be merged with and into the Company, with the
Company surviving the merger (as such, the "Surviving Corporation") as an
indirect wholly owned subsidiary of Parent (the "Merger"). At the effective time
of the Merger (the "Effective Time"), each outstanding Share (other than Shares
held (i) in the treasury of the Company or by Parent or any direct or indirect
wholly owned subsidiary of Parent immediately before the Effective Time, or (ii)
by stockholders, if any, who are entitled to and who properly exercise appraisal
rights under Delaware law) will be converted into the right to receive the Offer
Price in cash, without interest (the "Merger Consideration"). See Section 13 of
the Offer to Purchase.

     In the event the Purchaser acquires 90% or more of the outstanding Shares
at the time of acceptance for payment pursuant to the Offer or otherwise, the
Purchaser would be able to effect the Merger pursuant to the short-form merger
provisions of the Delaware General Corporation Law, without prior notice to, or
any action by, any other stockholder of the Company. In such event, the
Purchaser may effect the Merger without prior notice to, or any action by, any
other stockholder of the Company, promptly after its acceptance for payment of
Shares tendered into the Offer.

     The Merger Agreement provides that if on the scheduled expiration date of
the Offer, all of the conditions to the Offer have not been satisfied or waived,
the Purchaser may extend the Offer in its discretion. Furthermore, if
immediately prior to the initial expiration date of the Offer (as it may be
extended) the number of Shares tendered and not withdrawn equals less than 90%
of the outstanding Shares, the Purchaser may extend the Offer for a period not
to exceed 10 business days, notwithstanding that all conditions to the Offer
have been satisfied. If immediately after the expiration of the Offer at least a
majority of the outstanding Shares on a fully-diluted basis have been tendered
in the Offer and not withdrawn and the other conditions to the Offer have been
satisfied or waived, then the parties have agreed that the Purchaser will
purchase all Shares tendered pursuant to the Offer and the Company will, if
required by applicable law, promptly convene a special meeting of the
stockholders of the Company for the purpose of considering and taking action on
the Merger Agreement and the transactions contemplated thereby. The Company has
agreed, as soon as practicable after the expiration of the Offer, to file a
proxy statement relating to the Merger with the Securities and Exchange
Commission if less than 90% of the Shares have been tendered.

     The Purchaser and Parent have entered into Stockholder Agreements, each
dated as of July 28, 1999, with the Company's largest stockholder and all of its
directors and executive officers who own Shares. Those stockholders (the
"Stockholders") that entered into the Stockholder Agreements collectively own
approximately 46% of the outstanding Shares as of the date of the Merger
Agreement (excluding Shares held by the Company or any direct or indirect
subsidiary of the Company). Such Stockholders would collectively own
approximately 49% of the outstanding Shares, assuming that all outstanding stock
options were exercised. Under the Stockholder Agreements, each Stockholder
agreed, among other things, to validly tender the Shares beneficially owned by
it or him, as well as any Shares subsequently acquired by it or him. The
Stockholder Agreements are more fully described in Section 13 of the Offer to
Purchase. Pursuant to its Stockholder Agreement, the Company's largest
stockholder (owning approximately 44% of the outstanding Shares) has agreed to
vote its Shares in favor of the Merger, the adoption by the Company of the
Merger Agreement and the approval of the terms thereof and each of the other
transactions contemplated by the Merger Agreement, and agreed to vote against
(i) any Takeover Proposal (as defined in the Offer to Purchase) and (ii) certain
other actions by the Company. Pursuant to its Stockholder Agreement, such
Stockholder has also granted to Parent an irrevocable proxy pursuant to which it
irrevocably appointed representatives of Parent and the Purchaser as its proxies
and attorneys-in-fact to vote the Stockholder's Shares in the foregoing manner
at any time until the earlier to occur of the valid termination of the Merger
Agreement or the Effective Time.

     THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THERE HAVING BEEN
VALIDLY TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER AT LEAST
A MAJORITY OF THE OUTSTANDING SHARES, DETERMINED ON A FULLY DILUTED BASIS, AT
THE TIME OF ACCEPTANCE FOR PAYMENT.

     THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY APPROVED THE OFFER,
THE MERGER AND THE MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY,
HAS UNANIMOUSLY DETERMINED THAT THE TERMS OF EACH OF THE OFFER AND THE MERGER
ARE FAIR TO AND IN THE BEST INTERESTS OF THE COMPANY'S STOCKHOLDERS AND
UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS OF THE COMPANY TENDER THEIR SHARES
PURSUANT TO THE OFFER.

     The Offer and withdrawal rights will expire at 12:00 midnight, New York
City time, on August 30, 1999, unless the Offer is extended by the Purchaser.
Upon the terms and subject to the conditions of the Offer (including, if the
Offer is extended or amended, the terms and conditions of such extension or
amendment), the Purchaser will accept for payment and pay, as promptly as
practicable after the Expiration Date, for all Shares validly tendered prior to
the Expiration Date and not theretofore properly withdrawn in accordance with
Section 3 of the Offer to Purchase. The term "Expiration Date" means 12:00
midnight, New York City time, on August 30, 1999, unless and until the Offer is
extended in accordance with the Merger Agreement, in which event the term
"Expiration Date" shall mean the latest time and date at which the Offer, as so
extended, shall expire. For purposes of the Offer, the Purchaser will be deemed
to have accepted for payment, and thereby purchased, Shares validly tendered to
the Purchaser and not properly withdrawn as, if and when the Purchaser gives
oral or written notice to the Depositary of the Purchaser's acceptance of such
Shares for payment pursuant to the Offer.

     In all cases, payment for Shares accepted for payment pursuant to the Offer
will be made only after timely receipt by the Depositary of (i) certificates for
such Shares (or a timely Book-Entry Confirmation of a transfer of such Shares as
described in Section 2 of the Offer to Purchase), (ii) a Letter of Transmittal
(or facsimile thereof), properly completed and duly executed, together with any
required signature guarantees, or, in the case of a book-entry transfer effected
pursuant to the procedure set forth in Section 2 of the Offer to Purchase, an
Agent's Message (as defined in the Offer to Purchase), and (iii) any other
documents required by the Letter of Transmittal. Accordingly, tendering
stockholders may be paid at different times depending upon when certificates for
Shares or Book-Entry Confirmations with respect to Shares are actually received
by the Depositary. UNDER NO CIRCUMSTANCES WILL INTEREST BE PAID BY THE PURCHASER
ON THE PURCHASE PRICE OF THE SHARES, REGARDLESS OF ANY EXTENSION OF THE OFFER OR
ANY DELAY IN MAKING SUCH PAYMENT.

     If a stockholder desires to tender Shares pursuant to the Offer and such
stockholder's certificates for Shares are not immediately available or the
procedure for book-entry transfer cannot be completed on a timely basis or time
will not permit all required documents to reach the Depositary prior to the
Expiration Date, such stockholder's tender may be effected by following the
guaranteed delivery procedures specified in Section 2 of the Offer to Purchase.

     Neither the Purchaser nor Parent will pay any fees or commissions to any
broker or dealer or other person (other than the Information Agent and the
Depositary as described in the Offer to Purchase) in connection with the
solicitation of tenders of Shares pursuant to the Offer. However, you will be
reimbursed upon request for customary mailing and handling expenses incurred by
you in forwarding the enclosed offering materials to your customers.

     The Purchaser will pay stock transfer taxes with respect to the transfer
and sale of Shares to it or its order pursuant to the Offer, except as otherwise
provided in Instruction 6 to the Letter of Transmittal.

     Questions and requests for assistance or for additional copies of the
enclosed material may be directed to the Information Agent at the address and
telephone numbers set forth on the back cover of the enclosed Offer to Purchase.

                                          Very truly yours,

                                          D.F. King & Co., Inc.

     NOTHING CONTAINED HEREIN OR IN THE ENCLOSED DOCUMENTS SHALL RENDER YOU OR
ANY OTHER PERSON THE AGENT OF THE PURCHASER, PARENT, THE DEPOSITARY, THE
INFORMATION AGENT OR ANY AFFILIATE THEREOF OR AUTHORIZE YOU OR ANY OTHER PERSON
TO GIVE ANY INFORMATION OR USE ANY DOCUMENT OR MAKE ANY STATEMENTS ON BEHALF OF
ANY OF THEM WITH RESPECT TO THE OFFER OTHER THAN THE ENCLOSED DOCUMENTS AND THE
STATEMENTS CONTAINED THEREIN.

         THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT,

                         UNLESS THE OFFER IS EXTENDED.

To Our Clients:

     Enclosed for your consideration is an Offer to Purchase dated August 3,
1999 (the "Offer to Purchase"), and a related Letter of Transmittal (which,
together with any amendments or supplements thereto, constitute the "Offer")
relating to an offer by E Acqco Inc. (the "Purchaser"), an indirect wholly owned
subsidiary of Caradon Inc. ("Parent") and an indirect wholly owned subsidiary of
Caradon plc, to purchase all outstanding shares of common stock, $0.01 par value
(the "Shares"), of Easco, Inc. (the "Company"), at a price (the "Offer Price")
equal to $15.20 per Share, net to the seller in cash, without interest, as
described in the enclosed Offer to Purchase. Also enclosed is the Letter to
Stockholders of the Company from the President and Chief Executive Officer of
the Company accompanied by the Company's Solicitation/Recommendation Statement
on Schedule 14D-9.

     We are the holder of record of Shares held by us for your account. A tender
of such Shares can be made only by us as the holder of record and pursuant to
your instructions. The Letter of Transmittal is furnished to you for your
information only and cannot be used to tender Shares held by us for your
account.

     We request instructions as to whether you wish to tender any of or all the
Shares held by us for your account, pursuant to the terms and conditions set
forth in the Offer.

     Your attention is invited to the following:

          1. The tender price is equal to $15.20 per Share, net to the seller in
     cash, without interest, upon the terms and subject to the conditions set
     forth in the Offer.

          2. The Offer is being made for all outstanding Shares.

          3. The Offer is being made pursuant to the Agreement and Plan of
     Merger dated as of July 28, 1999 (the "Merger Agreement") among Parent, the
     Purchaser and the Company. Following the satisfaction or waiver of certain
     conditions, including approval by stockholders of the Company if such
     approval is required by applicable law, the Purchaser will be merged with
     and into the Company, with the Company surviving the merger (as such, the
     "Surviving Corporation") as an indirect wholly owned subsidiary of Parent
     (the "Merger"). At the effective time of the Merger (the "Effective Time"),
     each outstanding Share (other than Shares held (i) in the treasury of the
     Company or by Parent or any direct or indirect wholly owned subsidiary of
     Parent immediately before the Effective Time, or (ii) by stockholders, if
     any,
<PAGE>   2

     who are entitled to and who properly exercise appraisal rights under
     Delaware law)will be converted into the right to receive the Offer Price in
     cash, without interest (the "Merger Consideration").

          4. In the event the Purchaser acquires 90% or more of the outstanding
     Shares at the time of acceptance for payment pursuant to the Offer or
     otherwise, the Purchaser would be able to effect the Merger pursuant to the
     short-form merger provisions of the Delaware General Corporation Law,
     without prior notice to, or any action by, any other stockholder of the
     Company. In such event, the Purchaser may effect the Merger without prior
     notice to, or any action by, any other stockholder of the Company, promptly
     after its acceptance for payment of Shares tendered into the Offer. The
     Merger Agreement provides that if on the scheduled expiration date of the
     Offer, all of the conditions to the Offer have not been satisfied or
     waived, the Purchaser may extend the Offer in its discretion. Furthermore,
     if immediately prior to the initial expiration date of the Offer (as it may
     be extended) the number of Shares tendered and not withdrawn equals less
     than 90% of the outstanding Shares, the Purchaser may extend the Offer for
     a period not to exceed 10 business days, notwithstanding that all
     conditions to the Offer have been satisfied. If immediately after the
     expiration of the Offer at least a majority of the outstanding Shares on a
     fully-diluted basis have been tendered in the Offer and not withdrawn and
     the other conditions to the Offer have been satisfied or waived, then the
     parties have agreed that the Purchaser will purchase all Shares tendered
     pursuant to the Offer and the Company will, if required by applicable law,
     promptly convene a special meeting of the stockholders of the Company for
     the purpose of considering and taking action on the Merger Agreement and
     the transactions contemplated thereby. The Company has agreed, as soon as
     practicable after the expiration of the Offer, to file a proxy statement
     relating to the Merger with the Securities and Exchange Commission if less
     than 90% of the Shares have been tendered.

          5. The Purchaser and Parent have entered into Stockholder Agreements,
     each dated as of July 28, 1999, with the Company's largest stockholder and
     all of its directors and executive officers who own Shares. Those
     stockholders (the "Stockholders") that entered into the Stockholder
     Agreements collectively own approximately 46% of the outstanding Shares as
     of the date of the Merger Agreement (excluding Shares held by the Company
     or any direct or indirect subsidiary of the Company). Such Stockholders
     would collectively own approximately 49% of the outstanding Shares assuming
     that all outstanding stock options were exercised. Under the Stockholder
     Agreements, each Stockholder agreed, among other things, to validly tender
     the Shares beneficially owned by it or him, as well as any Shares
     subsequently acquired by it or him. The Stockholder Agreements are more
     fully described in Section 13 of the Offer to Purchase. Pursuant to its
     Stockholder Agreement, the Company's largest stockholder (owning
     approximately 44% of the outstanding Shares) has agreed to vote its Shares
     in favor of the Merger, the adoption by the Company of the Merger Agreement
     and the approval of the terms thereof and each of the other transactions
     contemplated by the Merger Agreement, and agreed to vote against (i) any
     Takeover Proposal (as defined in the Offer to Purchase) and (ii) certain
     other actions of the Company. Pursuant to its Stockholder Agreement, such
     Stockholder has also granted to Parent an irrevocable proxy pursuant to
     which it irrevocably appointed representatives of Parent and the Purchaser
     as its proxies and attorneys-in-fact to vote the Stockholder's Shares in
     the foregoing manner at any time until the earlier to occur of the valid
     termination of the Merger Agreement or the Effective Time.

          6. THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THERE HAVING
     BEEN VALIDLY TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE
     OFFER AT LEAST A MAJORITY OF THE OUTSTANDING SHARES, DETERMINED ON A FULLY
     DILUTED BASIS, AT THE TIME OF ACCEPTANCE FOR PAYMENT.

          7. THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY APPROVED THE
     OFFER, THE MERGER AND THE MERGER AGREEMENT AND THE TRANSACTIONS
     CONTEMPLATED THEREBY, HAS UNANIMOUSLY DETERMINED THAT THE TERMS OF EACH OF
     THE OFFER AND THE MERGER ARE FAIR TO AND IN THE BEST INTERESTS OF THE
     COMPANY'S STOCKHOLDERS AND UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS OF THE
     COMPANY TENDER THEIR SHARES PURSUANT TO THE OFFER.

          8. The Offer and withdrawal rights will expire at 12:00 midnight, New
     York City time, on August 30, 1999, unless the Offer is extended by the
     Purchaser. Upon the terms and subject to the conditions of the Offer
     (including, if the Offer is extended or amended, the terms and conditions
     of any

                                        2
<PAGE>   3

     such extension or amendment), the Purchaser will accept for payment and
     pay, as promptly as practicable after the Expiration Date, for all Shares
     validly tendered prior to the Expiration Date and not theretofore properly
     withdrawn in accordance with Section 3 of the Offer to Purchase. The term
     "Expiration Date" means 12:00 midnight, New York City time, on August 30,
     1999, unless and until the Offer is extended in accordance with the Merger
     Agreement, in which event the term "Expiration Date" shall mean the latest
     time and date at which the Offer, as so extended, shall expire. For
     purposes of the Offer, the Purchaser will be deemed to have accepted for
     payment, and thereby purchased, Shares validly tendered to the Purchaser
     and not properly withdrawn as, if and when the Purchaser gives oral or
     written notice to ChaseMellon Shareholder Services, L.L.C. (the
     "Depositary") of the Purchaser's acceptance of such Shares for payment
     pursuant to the Offer. In all cases, payment for Shares accepted for
     payment pursuant to the Offer will be made only after timely receipt by the
     Depositary of (i) certificates for such Shares (or a timely Book-Entry
     Confirmation of a transfer of such Shares as described in Section 2 of the
     Offer to Purchase), (ii) a Letter of Transmittal (or facsimile thereof),
     properly completed and duly executed, together with any required signature
     guarantees, or, in the case of a book-entry transfer effected pursuant to
     the procedure set forth in Section 2 of the Offer to Purchase, an Agent's
     Message (as defined in the Offer to Purchase), and (iii) any other
     documents required by the Letter of Transmittal. Accordingly, tendering
     stockholders may be paid at different times depending upon when
     certificates for Shares or Book-Entry Confirmations with respect to Shares
     are actually received by the Depositary. UNDER NO CIRCUMSTANCES WILL
     INTEREST BE PAID BY THE PURCHASER ON THE PURCHASE PRICE OF THE SHARES,
     REGARDLESS OF ANY EXTENSION OF THE OFFER OR ANY DELAY IN MAKING SUCH
     PAYMENT.

          9. The Purchaser will pay any stock transfer taxes with respect to the
     transfer and sale of Shares to it or its order pursuant to the Offer,
     except as otherwise provided in Instruction 6 of the Letter of Transmittal.

     The Offer is being made solely by the Offer to Purchase and the related
Letter of Transmittal and is being made to all holders of Shares. Neither the
Purchaser nor Parent is aware of any jurisdiction in which the making of the
Offer or the acceptance thereof would not be in compliance with the laws of such
jurisdiction. To the extent the Purchaser or Parent becomes aware of any state
law that would limit the class of offerees in the Offer, the Purchaser will
amend the Offer and, depending on the timing of such amendment, if any, will
extend the Offer to provide adequate dissemination of such information to
holders of Shares prior to the expiration of the Offer. In any jurisdiction
where securities or other laws require the offer to be made by a licensed broker
or dealer, the Offer shall be deemed to be made on behalf of the Purchaser by

cause and not to willful neglect.
(2) FAILURE TO REPORT CERTAIN DIVIDEND AND INTEREST PAYMENTS.--If you fail to
include any portion of an includible payment for interest, dividends, or
patronage dividends in gross income, such failure will be treated as being due
to negligence and will be subject to a penalty of 5% on any portion of an
underpayment attributable to that failure unless there is a clear and convincing
evidence to the contrary.
(3) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING.--If you
make a false state with no reasonable basis which results in no imposition of
backup withholding, you are subject to a penalty of $500.
(4) CRIMINAL PENALTY FOR FALSIFYING INFORMATION.--Willfully falsifying
certifications or affirmations may subject you to criminal penalties including
fines and/or imprisonment.

                         CARADON INC. AGREES TO ACQUIRE
                     EASCO, INC. FOR $15.20 CASH PER SHARE

     WEYBRIDGE, ENGLAND and GIRARD, OHIO, July 28, 1999 -- Caradon Inc., a US
wholly owned subsidiary of Caradon plc, and Easco, Inc. (NASDAQ: ESCO) today
jointly announced that Caradon and Easco have signed a definitive agreement
pursuant to which Caradon will acquire all of the outstanding common stock of
Easco for a cash price of $15.20 per share, or approximately $155 million in the
aggregate. The agreement was unanimously approved by the boards of directors of
both companies.

     Under the terms of the agreement, a Caradon subsidiary will make a cash
tender offer for all Easco shares at a price of $15.20 per share, and upon
successful completion of the tender offer the Easco stock not tendered will be
cashed out at $15.20 per share in a statutory merger. In connection with the
transaction, Easco has changed the record date for its previously declared
regular quarterly cash dividend of $0.01 per share. The new record date for the
dividend is September 15, 1999, payable on September 30, 1999. Easco's largest
stockholder, American Industrial Partners, and each of Easco's stock-owning
directors and executive officers, collectively owning approximately 46% of
Easco's outstanding shares, have entered into separate agreements with Caradon
supporting the transaction.

     The acquisition of Easco is subject to a majority of Easco's fully diluted
shares being tendered in the tender offer and not withdrawn, expiration of the
Hart-Scott-Rodino review period and other customary conditions.

     Jurgen Hintz, Group Chief Executive of Caradon plc, said, "The acquisition
of Easco is a significant step in Caradon's continuing commitment to expand our
highly successful and growing North American aluminum extrusion business. The
combined businesses will constitute one of the largest aluminum extrusion
operations in North America."

     Norman E. Wells, Jr., President and Chief Executive Officer of Easco,
stated, "This merger combines the capabilities of two excellent companies in the
aluminum extrusion industry. We are pleased that the merger also provides our
stockholders with an exceptional value-maximizing opportunity."

     Caradon Inc. is a wholly-owned subsidiary of Caradon plc, of Weybridge,
England. Caradon plc is a major international group of companies operating
across Europe and North America. Caradon plc is committed to growing each of its
four product sectors -- plumbing, electrical, extrusions and security printing.

     Easco, Inc. is the largest independent extruder of soft alloy aluminum
products in the United States and is a leading producer of painted extrusions.
The company operates 21 aluminum extrusion presses and three casting facilities.
Its products include standard and custom profiles, conduit and drawn tubing.
Easco's largest shareholder is American Industrial Partners, a private equity
firm with offices in New York and San Francisco.

           ACQUISITION OF US EXTRUSION BUSINESS FOR $155M ((POUND)97m)


Caradon today announced that it has signed a definitive agreement pursuant to
which Caradon will acquire all of the outstanding shares of common stock of
Easco, Inc. ("Easco"), a US publicly traded company, at a cash price of $15.20
per share, valuing the net equity at approximately $155m ((pound)97m).

Caradon has received irrevocable undertakings from Easco's largest stockholder,
American Industrial Partners, and each of Easco's directors and executive
officers, collectively owning approximately 46% of Easco's outstanding shares.

Easco is the largest independent aluminium extrusion company of soft alloy
products in North America, serving transportation, building, electronics,
consumer durables and distribution markets. It employs 2000 people and has
eleven manufacturing sites in the United States.

The turnover in the year to December 1998 was $314m ((pound)197m) with EBITDA of
$32m ((pound)20m) and profit before tax of $13.3m ((pound)8.4m). Net operating
assets at the end of December 1998 was $89.5m ((pound)56.3m) and net debt of
$77m ((pound)48m).

Caradon has substantial aluminium extrusion operations in North America which
support market leadership in Canada and strong regional positions in the US.

In the half year to June 1999 the Caradon Extrusion sector reported operating
profits up 30% to (pound)10.8m on a sales increase of 15% at (pound)112m. In the
full year to December 1998 operating profits were (pound)18.3m (up16% on
previous year) on sales of (pound)196.1m.

Commenting on the proposed acquisition, Jurgen Hintz, Group Chief Executive,
said:

   "This acquisition provides Caradon the opportunity to more than double our
   buoyant and profitable Aluminium Extrusion business. The combination with
   Easco creates one of the largest competitors in the growing $4 billion North
   American Extrusion market. It promises substantial synergies, bigger and
   better manufacturing capacity, improved mix of customer segments, and access
   to important low cost remelt capacity.

   This business combination offers significant opportunities to create
shareholder value.

The management and employees of Easco provide a further advance in our ability
to serve customers. We welcome Norman Wells and his team to the Caradon Group."

Wasserstein Perella & Co., Inc. advised Easco in the transaction and KPMG
Corporate Finance advised Caradon.

                                   CARADON PLC

         E Acqco Inc. (the "Purchaser"), an indirect wholly owned subsidiary of
Caradon Inc. ("Parent"), and an indirect wholly owned subsidiary of Caradon plc,
is offering to purchase all outstanding shares of Common Stock, $0.01 par value

Share, net to the seller in cash, without interest, upon the terms and subject
to the conditions set forth in the Offer to Purchase, dated August 3, 1999 (the

THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT, NEW YORK CITY
TIME, ON MONDAY, AUGUST 30, 1999, UNLESS THE OFFER IS EXTENDED.
- --------------------------------------------------------------------------------

         THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THERE HAVING BEEN
VALIDLY TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION DATE OF THE OFFER
SUCH NUMBER OF SHARES THAT WOULD CONSTITUTE A MAJORITY OF THE OUTSTANDING SHARES
AT THE DATE OF THE EXPIRATION OF THE OFFER


<PAGE>   2


(ASSUMING THE EXERCISE OF ALL OPTIONS TO PURCHASE SHARES OUTSTANDING AT THE
EXPIRATION DATE OF THE OFFER) (THE "MINIMUM CONDITION"). THE OFFER IS ALSO
CONDITIONED UPON THE WAITING PERIOD UNDER THE HSR ACT (AS DEFINED IN THE OFFER
TO PURCHASE) APPLICABLE TO THE PURCHASE OF SHARES PURSUANT TO THE OFFER HAVING
EXPIRED OR BEEN TERMINATED. THE OFFER IS ALSO SUBJECT TO OTHER TERMS AND
CONDITIONS.

         The Offer is being made pursuant to an Agreement and Plan of Merger
dated as of July 28, 1999 (the "Merger Agreement"), among Parent, the Purchaser
and the Company. The Merger Agreement provides that, among other things, as soon
as practicable after the purchase of Shares pursuant to the Offer and the
satisfaction of the other conditions set forth in the Merger Agreement and in
accordance with the relevant provisions of the Delaware General Corporation Law,
as amended (the "Delaware Law"), the Purchaser will be merged with and into the
Company (the "Merger"). If the Purchaser acquires at least 90% of the
outstanding Shares pursuant to the Offer, the Purchaser would be able to effect
the Merger pursuant to the "short-form" merger provisions of Section 253 of the
Delaware Law, without prior notice to, or any action by, any stockholder of the
Company. Following consummation of the Merger, the Company will continue as the
surviving corporation (the "Surviving Corporation") and will be an indirect
wholly owned subsidiary of Parent. At the effective time of the Merger (the
"Effective Time"), each Share that is issued and outstanding (other than Shares
held in the treasury of the Company or by Parent, the Purchaser or any other
direct or indirect wholly owned subsidiary of Parent or Shares with respect to
which appraisal rights are properly exercised under the Delaware Law) will be
converted into the right to receive from the Surviving Corporation $15.20 (or
any higher price that may be paid for each Share pursuant to the Offer) in cash,
without interest thereon.

         THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY APPROVED THE
OFFER, THE MERGER AND THE MERGER AGREEMENT AND THE OTHER TRANSACTIONS
CONTEMPLATED THEREBY, HAS UNANIMOUSLY DETERMINED THAT THE TERMS OF EACH OF THE
OFFER AND THE MERGER ARE FAIR TO AND IN THE BEST INTERESTS OF THE COMPANY'S
STOCKHOLDERS AND UNANIMOUSLY RECOMMENDS THAT THE HOLDERS OF SHARES TENDER THEIR
SHARES PURSUANT TO THE OFFER.

         As a condition to Parent's willingness to enter into the Merger
Agreement, Parent and the Purchaser entered into stockholder agreements dated
as of July 28, 1999 with each of American Industrial Partners Capital Fund,
L.P. ("AIP"), which holds 4,239,470 Shares, representing approximately 44% of
the outstanding Shares, and certain directors and executive officers of the
Company, who collectively hold 226,800 Shares, representing approximately 2.3%
of the outstanding Shares.  Pursuant to its stockholder agreement, AIP has
agreed, among other things, to tender the Shares held by it in the Offer and
granted the Purchaser an irrevocable proxy to vote such Shares in connection
with any meeting of the stockholders of the Company in favor of the Merger and
against any action that would interfere with the Merger, including any
proposal by a third party to acquire the Company. Pursuant to his respective
stockholder agreement, each of the directors and executive officers has agreed,
among other things, to tender the Shares held by him in the Offer.

         For purposes of the Offer, the Purchaser will be deemed to have
accepted for payment, and thereby purchased, Shares validly tendered and not
withdrawn as, if and when the Purchaser gives oral or written notice to
ChaseMellon Shareholder Services, L.L.C. (the "Depositary") of the Purchaser's
acceptance of such Shares for payment pursuant to the Offer. Upon the terms and
subject to the conditions of the Offer, payment for Shares purchased pursuant to
the Offer will be made by deposit of the purchase price with the Depositary,
which will act as agent for tendering stockholders for the purpose of receiving
payment from the Purchaser and transmitting such payment to tendering
stockholders. Under no circumstances will interest be paid by the Purchaser
because of any delay in making such payment. In all cases, payment for Shares
tendered and accepted for payment pursuant to the Offer will be made only after
timely receipt by the Depositary of (i) certificates for such Shares or timely
confirmation of a book-entry transfer of such Shares into the Depositary's
account at the Book-Entry Transfer Facility (as defined in Section 2 of the
Offer to Purchase) pursuant to the procedures set forth in the Offer to
Purchase, (ii) a properly completed and duly executed Letter of Transmittal (or
a manually signed facsimile thereof), with all required signature




                                      -2-

guarantees or, in the case of a book-entry transfer, an Agent's Message (as
defined in Section 2 of the Offer to Purchase) and (iii) any other documents
required by the Letter of Transmittal.

         If any of the conditions set forth in the Offer to Purchase that relate
to the Purchaser's obligation to purchase the Shares have not been satisfied by
12:00 midnight, New York City time, on Monday, August 30, 1999 (or any other

         Subject to the limitations set forth in the Offer and the Merger

stockholder to withdraw such stockholder's Shares.

tenders of Shares made pursuant to the Offer are irrevocable, except that such
Shares may be withdrawn at any time prior to the Expiration Date and, unless

withdrawal must specify the name of the person who tendered the Shares to be

otherwise identified to the Depositary, then, prior to the physical release of
such certificates, the serial numbers shown on such certificates must be
submitted to the Depositary and, unless such Shares have been tendered by an

determination will be final and binding on all parties. None of the Purchaser,

to give notification of any defects or irregularities in any notice of
withdrawal or incur any liability for failure to give such notification.

WEYBRIDGE, ENGLAND, August 3, 1999 - Caradon Inc., the wholly owned U.S. holding
company of United Kingdom industrial group Caradon plc, announced today that an
indirect wholly owned subsidiary has commenced its previously announced tender
offer for shares of common stock of Easco, Inc. (NASDAQ: ESCO). The tender
offer, which is being made pursuant to an Agreement and Plan of Merger dated
July 28, 1999, is scheduled to expire at 12:00 midnight, New York City time, on
Monday, August 30, 1999, unless extended. Following the consummation of the
tender offer, Caradon intends to complete a merger to acquire all of the
remaining shares of Easco common stock that are not tendered in the offer.

The Board of Directors of Easco has unanimously approved the tender offer, the
merger and the other transactions contemplated by the Agreement and Plan of
Merger, unanimously determined that the terms of the tender offer and merger are
fair to and in the best interests of Easco's stockholders, and unanimously
recommends that stockholders tender their shares pursuant to the offer.

entered into separate agreements with Caradon in support of the transaction.
Under those agreements, the stockholders (who collectively own approximately 46%
of Easco's outstanding shares) have agreed to tender all of their shares in the
offer.

The tender offer is conditioned upon, among other things, there being validly
tendered and not withdrawn prior to the expiration of the offer that number of
shares which represents at least a majority of the total number of shares
outstanding on the date shares are accepted for payment, the expiration or
termination of the customary antitrust waiting period and other customary
conditions. Other terms and conditions of the tender offer are set forth in the
definitive tender offer documents being filed with the Securities and Exchange
Commission and mailed to Easco's stockholders.

ChaseMellon Shareholder Services, L.L.C. will act as depositary for the tender
offer and D.F. King & Co., Inc. will act as information agent.

Caradon Inc. is a wholly owned subsidiary of Caradon plc, of Weybridge, England.
Caradon plc is a major international group of companies operating in four
product sectors -- plumbing, electrical, extrusions and security printing --
across Europe and North America.

           5.3.3     only one Term is specified which:

                     (a)        does not overrun the Final Maturity Date; and

                     (b)        is a period of an approved duration or of an
                                optional duration; and

           5.3.4     the payment instructions comply with Clause 9 (Payments).

           In this Clause:

           "APPROVED DURATION" means a period of 1, 2, 3 or 6 months; and


                                      -11-
<PAGE>   12

           "OPTIONAL DURATION" means any other period not exceeding 12 months.

           SELECTION OF TERM OF OPTIONAL DURATION

5.4        If the relevant Borrower selects a Term of an optional duration, it
           may also select at the time of the telephone notice of Utilisation
           and in the relevant Request a Term of any approved duration to apply
           if the selection of a Term of an optional duration becomes
           ineffective in accordance with Clause 5.5.2.

5.5        If:

           5.5.1     the relevant Borrower requests a Term of an optional
                     duration; and

           5.5.2     the Bank notifies such Borrower not later than 10.30 a.m.
                     on the date of receipt by it of the relevant Request or
                     telephone notice of Utilisation pursuant to Clause 5.1 or
                     Clause 5.2 respectively that it does not agree to that
                     request,

           the Term for the proposed Utilisation shall be the alternative period
           specified in the telephone notice of Utilisation or the relevant
           Request or, in the absence of any alternative selection, 3 months.

           PAYMENT OF PROCEEDS

5.6        Subject to the terms of this Agreement, the Bank shall make the
           Advance available to the relevant Borrower on the relevant
           Utilisation Date.

6.         CANCELLATION

           AUTOMATIC CANCELLATION OF THE COMMITMENT

6.1        The Commitment shall be automatically cancelled at close of business

6.2        The Company may, without penalty and by giving not less than 15 days'
           prior notice to the Bank, cancel the Commitment in whole or in part.

6.3        A notice of cancellation will be irrevocable and shall specify:

           6.3.1     the date on which the cancellation is to become effective;
                     and

           6.3.2     the amount of the Commitment to be cancelled.

6.4        Any cancellation may only take effect in respect of the unutilised
           portion of the Commitment as at the date the notice is to be
           effective.

           NO REINSTATEMENT

6.5        No amount of the Commitment cancelled under this Agreement may
           subsequently be reinstated.

7.         INTEREST

           INTEREST RATE

7.1        The rate of interest on each Advance for its Term is the rate per
           annum determined by the Bank to be the aggregate of the applicable:

           7.1.1     Margin,

           7.1.2     LIBOR; and

           7.1.3     Mandatory Costs.

           DUE DATES

7.2        Except as otherwise provided in this Agreement, accrued interest on
           each Advance is payable on its Maturity Date and also, in the case of
           an Advance with a term longer than six months, on the date falling
           six months after its Utilisation Date.

           DEFAULT INTEREST

7.3        If any Borrower fails to pay any amount payable by it under this
           Agreement, it shall, on demand by the Bank from time to time, pay
           interest on the overdue amount from the due date up to the date of
           actual payment, after as well as before judgment, at a rate (the
           "DEFAULT RATE") determined by the Bank to be one (1) per cent. per
           annum above the higher of:

           7.3.1     the rate on the overdue amount under Clause 7.1 (Interest
                     rate) immediately before the due date (but only if the
                     overdue amount is an Advance (or part thereof) and only for
                     the period up to and including the Maturity Date of that
                     Advance); and

           7.3.2     the rate which would have been payable if the overdue
                     amount had, during the period of non-payment, constituted
                     an Advance in the currency of the overdue amount for such
                     successive Terms of such duration (not exceeding three
                     months) as the Bank may reasonably determine (each a
                     "DESIGNATED TERM").

7.4        The default rate will be determined on the first day of, or two
           Business Days before the first day of, the relevant Designated Term,
           as appropriate.

7.5        If the Bank determines that deposits in the currency of the overdue
           amount are not at the relevant time being made available by leading
           banks in the London Interbank Market, the default rate will be
           determined by reference to the cost of funds to the Bank from
           whatever sources it may reasonably select.

7.6        Default interest shall be compounded at the end of each Designated
           Term until it is paid.

           NOTIFICATION OF RATES OF INTEREST

7.7        The Bank shall promptly notify the relevant Borrower of the
           determination of any applicable rate of interest under this
           Agreement.

8.         REPAYMENT AND PREPAYMENT

           REPAYMENT OF ADVANCES

8.1        Each Borrower shall repay each Advance made to it in full on its
           Maturity Date to the Bank. If an Advance (the "NEW ADVANCE") is to be
           made to a Borrower on the day on which another Advance (the "MATURING
           ADVANCE") in the same currency is due to be repaid by such Borrower
           then, subject to the terms of this Agreement and so long as the
           conditions referred to in Clause 4.2 shall have been satisfied in
           relation to the New Advance:

           8.1.1     the Maturing Advance shall be deemed to have been repaid on
                     its Maturity Date either in whole (if the New Advance is
                     equal to or greater than the Maturing Advance) or in part
                     (if the New Advance is less than the Maturing Advance); and

           8.1.2     to the extent that a Maturing Advance is so deemed to have
                     been repaid, the principal amount of the New Advance to be
                     made on such a date shall be deemed to have been credited
                     to the account of such Borrower by the Bank in accordance
                     with the terms of this Agreement and, as the case may be:

                     (a)        the Bank shall only be obliged to make available
                                to such Borrower pursuant to Clause 5.6 a
                                principal amount equal to the amount (if any) by
                                which the New Advance exceeds the Maturing
                                Advance; or

                     (b)        such Borrower shall only be obliged to pay to
                                the Bank pursuant to this Clause 8.1 a principal
                                amount equal to the amount by which the Maturing
                                Advance exceeds the New Advance.

8.2        On the Final Maturity Date, all outstanding Advances and other sums
           (if any) then owing under this Agreement shall in any event be repaid
           or paid in full.

           PREPAYMENT OF ADVANCES

8.3        Any Borrower may, without penalty and on giving not less than 15
           days' prior notice to the Bank, prepay all or any part of an Advance,
           but if in part, in a minimum amount of Pound Sterling 1,000,000 and
           an integral multiple of Pound Sterling 100,000 (or the comparable
           amount in any Optional Currency).

8.4        Any notice by a Borrower of prepayment under this Agreement is
           irrevocable.

8.5        Should any person or group of persons, acting either individually or
           in concert (as defined in the City Code on Take Overs and Mergers
           effective as at the date of this Agreement) otherwise than with the
           consent of the Bank acquire


                                      -14-
<PAGE>   15

           control of the Company (and for the purpose of this Clause a single
           person or group of persons shall have acquired control if it or they
           own or hold more than 50% (fifty per cent.) of the issued share
           capital of the Company having the right to attend and vote at general
           meetings of the Company or more than 50% (fifty per cent.) of such
           rights), then:

           8.5.1     the Company shall immediately upon becoming aware thereof
                     notify the Bank specifying the date of such acquisition and
                     the name of such person or persons acquiring control; and

           8.5.2     thereafter no Borrower shall be permitted to request an
                     Advance unless the terms of the acquisition of control of
                     the Company were approved by the Board of Directors of the
                     Company and the Maturity Date for any Advance requested
                     falls on a date not more than three months after the
                     expiration of the 30 day period referred to in Clause 8.6.

8.6        If the terms of the acquisition of control of the Company were
           approved by the Board of Directors of the Company, the Bank shall
           consult with the Company during the period of 30 days after receipt
           of the notification from the Company referred to in sub-Clause 8.5.1
           and shall be entitled to give notice of continuance of the Facility
           provided hereunder to the Company. Upon receipt of such notice of
           continuance, the right of the Borrowers to request an Advance without
           the limitation referred to in sub-Clause 8.5.2 shall be reinstated.

8.7        If the terms of the acquisition of control of the Company were
           approved by the Board of Directors of the Company but, at the end of
           the period of 30 days referred to in Clause 8.6 above, the Company
           has not received a notice of continuance then:

           8.7.1     the Facility shall be cancelled;

           8.7.2     any outstanding Advances with Maturity Dates falling later
                     than three months after the end of such period shall be
                     prepaid on the date falling three months after the end of
                     such period, together with accrued interest thereon up to
                     the date of payment and all other amounts payable to the
                     Bank hereunder; and

           8.7.3     any outstanding Advances with Maturity Dates falling not
                     later than three months after the end of such period shall
                     be repaid on their respective Maturity Dates.

8.8        If the terms of the acquisition of control of the Company were not
           approved by the Board of Directors of the Company, then unless the
           Bank shall have confirmed within 2 days of receipt of the notice
           referred to in sub-Clause 8.5.1 that the Facility shall be continued,
           the Facility shall be cancelled and any outstanding Advances shall be
           repayable on demand by the Bank together with accrued interest
           thereon up to the date of payment and all other amounts payable to
           the Bank hereunder.

8.9        Any prepayment under this Agreement shall be made together with
           accrued interest on the amount prepaid together with any amount
           payable to the Bank pursuant to Clause 22.3.

8.10       No Advance may be prepaid otherwise than in accordance with the
           express terms of this Agreement.

9.1        All payments by each of the Borrowers or the Bank under this
           Agreement shall be made to such account at such office or bank in the
           principal financial centre of the relevant currency as it may notify
           the other or to such other place as may be agreed between the parties
           for this purpose.

                     country of that Optional Currency, in immediately available
                     funds, or at such times or in such funds as the Bank may
                     specify to the relevant Borrower as being customary at the
                     time for the settlement of transactions in the relevant
                     currency in the place for payment.

           CURRENCY

           Subject to clauses 9.6 and 9.7:

9.3        A repayment or prepayment of an Advance is payable in the currency in
           which the Advance is denominated.

9.4        Interest is payable in the currency in which the relevant amount in
           respect of which it is payable is denominated.

9.5        Any other amount payable under this Agreement is, except as otherwise
           provided in this Agreement, payable in Sterling.

           Advance requested to be denominated in the currency of a
           Participating Member State shall be made in the euro unit.

9.7        If and to the extent that any EMU legislation provides that an amount

           of a given Participating Member State and payable within that
           Participating Member State


                                      -16-

           by crediting an account of the creditor, can be paid by the debtor
           either in the euro unit or in that national currency unit, a Party
           shall be entitled to pay that amount either in the euro unit or in
           the relevant national currency unit.

           SET-OFF AND COUNTERCLAIM

9.8        All payments made by each of the Borrowers under this Agreement shall

9.9        If a payment under this Agreement is due on a day which is not a
           Business Day, then the due date for the payment shall instead be the
           next Business Day.

9.10       During any extension of the due date for payment of any principal
           under this Agreement pursuant to Clause 9.9 above interest is payable
           on the principal at the rate payable on the original due date.

           PARTIAL PAYMENTS

9.11       If the Bank receives a payment insufficient to discharge all the
           amounts then due and payable by any Borrower under this Agreement,
           the Bank shall apply that payment towards the obligations of such
           Borrower under this Agreement in the following order:

           9.11.1    firstly, in or towards payment of any unpaid costs and
                     expenses of the Bank under this Agreement;

           9.11.2    secondly, in or towards payment of any accrued fees due but
                     unpaid under Clause 19.2 (Commitment Fee);

           9.11.3    thirdly, in or towards payment of any accrued interest due
                     but unpaid under this Agreement;

           9.11.4    fourthly, in or towards payment of any principal due but
                     unpaid under this Agreement, and

           9.11.5    fifthly, in or towards payment of any other sum due but
                     unpaid under this Agreement.

9.12       The Bank may vary the order set out in Clauses 9.11.1 to 9.11.5
           above.

9.13       Clauses 9.11 and 9.12 above shall override any appropriation made by
           any Borrower.

10.        OPTIONAL CURRENCIES

           SELECTION

10.1       No Borrower may request an Advance denominated in an Optional
           Currency unless the Bank has confirmed to such Borrower that the
           Optional Currency is readily available and freely transferable in the
           London foreign exchange market.


                                      -17-
<PAGE>   18

           CHANGE OF CURRENCY

10.2       If, on the Rate Fixing Day of an Advance to be denominated in an
           Optional Currency, the Bank determines that:

           10.2.1    it is impracticable for reasons beyond its control for the
                     Bank to fund the Advance for its Term in that Optional
                     Currency in the ordinary course of business in the London
                     Interbank Market; or

           10.2.2    the use of the proposed Optional Currency might contravene
                     any law or regulation,

           then:

           10.2.3    the Bank shall promptly and in any event before 10.30 a.m.
                     on that Rate Fixing Day notify the relevant Borrower;

           10.2.4    if the Bank receives notice from the relevant Borrower by
                     11.30 a.m. on that Rate Fixing Day to that effect, the
                     Advance will not be made; and

           10.2.5    if the Bank does not receive any notice under sub-Clause
                     10.2.4 above, the Advance will be denominated instead in
                     Sterling in an amount equal to its Original Sterling
                     Amount.

           NOTIFICATION OF RATES AND AMOUNTS

10.3       The Bank shall, on request, promptly notify the relevant Borrower of
           any applicable Bank's Spot Rate of Exchange or Original Sterling
           Amount promptly after it has been ascertained.

10.4       If an Advance which has been drawn in an Optional Currency is
           reborrowed in the same Optional Currency immediately following its
           repayment, then the Original Sterling Amount of such new Advance
           denominated in such Optional Currency shall be recalculated for the
           new Term in accordance with the terms and conditions of this
           Agreement and if on the relevant Utilisation Date the aggregate
           Original Sterling Amount of all Advances outstanding on such date
           exceeds the Commitment, then any excess shall be repaid to the Bank
           by the relevant Borrower upon the Bank's first written demand.

11.        TAXES

           GROSS-UP

11.1       All payments by each of the Borrowers under this Agreement shall be
           made without any deductions and free and clear of and without
           deduction for or on account of any Relevant Taxes except to the
           extent that any Borrower is required by law to make payment subject
           to any such taxes. If any Relevant Tax or amounts in respect of any
           Relevant Tax must be deducted from any amounts payable or paid by any
           Borrower hereunder, such Borrower shall pay such additional amounts
           as may be necessary to ensure that the Bank receives a


                                      -18-

           net amount equal to the full amount which it would have received had
           payment not been made subject to tax.

           "RELEVANT TAX" in relation to any payment which falls to be made
           hereunder means any present or future taxes of any nature now or
           hereafter imposed by the laws of (i) the United Kingdom, (ii) any
           other jurisdiction from which, or through which, such payment is made
           or to the taxation laws of which the relevant Borrower is at the time
           of such payment subject, (iii) any political sub-division of the
           United Kingdom or any such other jurisdiction or (iv) any federation
           or association of states of which the United Kingdom or any such
           other jurisdiction is, at the time of such payment, a member.

           TAX RECEIPTS

11.2       All Relevant Taxes required by law to be deducted or withheld by any
           Borrower from any amount paid or payable under this Agreement shall
           be paid by such Borrower when due (unless the obligation to pay is
           being disputed in good faith) and such Borrower shall, within 30 days
           of the payment being made, deliver to the Bank evidence satisfactory
           to the Bank (including all relevant tax receipts) that the payment
           has been duly remitted to the appropriate authority.

           TAX CREDITS

11.3       If any Borrower pays any additional amount (a "TAX PAYMENT") under
           Clause 11.1 and the Bank effectively obtains a refund of tax, or a
           relief or credit against tax by reason of that Tax Payment (a "TAX
           CREDIT"), and the Bank is able to identify the Tax Credit as being
           attributable to the Tax Payment, then the Bank shall reimburse to the
           relevant Borrower such amount as the Bank reasonably determines to be
           the proportion of the Tax Credit as will leave the Bank (after that
           reimbursement) in no better or worse position that it would have been
           if the Tax Payment had not been required. Nothing in this Clause
           interferes with the right of the Bank to arrange its tax affairs in
           whatever manner it thinks fit and, without prejudice to the
           foregoing, the Bank is under no obligation to claim a Tax Credit, or
           to claim a Tax Credit in priority to any other claim, relief, credit
           or deduction available to it. The Bank is not obliged to disclose any
           information regarding its tax affairs or computations to any
           Borrower.

           QUALIFYING BANK

11.4       If, otherwise than as a result of the introduction of, change in, or
           change in the interpretation, administration or application of, any
           law or regulation or any practice or concession of the Inland Revenue
           after the Signing Date, the Bank ceases to be a Qualifying Bank no
           Borrower shall be liable to pay to the Bank under Clause 11.1
           (Gross-up) any amount in respect of taxes levied or imposed by the UK
           or any taxing authority thereof or therein in excess of the amount it
           would have been obliged to pay if the Bank had been or had not ceased
           to be a Qualifying Bank.

12.        MARKET DISRUPTION

           MARKET DISRUPTION

12.1       If, in relation to any proposed Utilisation:

           12.1.1    the Bank is unable to obtain from leading banks a rate for
                     the purposes of determining the applicable LIBOR or the
                     Bank otherwise determines that adequate and fair means do
                     not exist for ascertaining the applicable LIBOR; or

           12.1.2    in the opinion of the Bank:

                     (a)        matching deposits may not be available to it in
                                the London Interbank Market in the ordinary
                                course of business to fund an Advance; or

                     (b)        the cost to it of matching deposits in the
                                London Interbank Market would be in excess of
                                the relevant LIBOR,

                     the Bank shall notify the Company by 10.30 a.m. or as soon
                     as is practicable thereafter on the Rate Fixing Day of the
                     fact and that this Clause is in operation.

12.2       After any notification under Clause 12.1 above:

           12.2.1    subject to sub-Clause 12.2.3 below the relevant Advance
                     shall be made in Sterling in an amount equal to its
                     Original Sterling Amount (unless Sterling was the original
                     currency of the relevant Advance);

           12.2.2    subject to sub-Clause 12.2.3 below, no further notices of
                     Utilisation by telephone or Requests for Advances to be
                     denominated in the original currency of the affected
                     Advance may be delivered until the Bank notifies the
                     Company that the event specified in the notification no
                     longer prevails;

           12.2.3    the relevant Borrower may, by notice to the Bank by 11.00
                     a.m. (or, if later, within 30 minutes of receipt by the
                     Company of a notification under sub-Clause 12.1.2) on the
                     Rate Fixing Day: (i) elect for the notice of Utilisation by
                     telephone or the Request to be cancelled without penalty;
                     (ii) if the Advance was to be made in an Optional Currency,
                     elect for the Advance to be made in an Optional Currency
                     other than a currency affected by the event specified in
                     the notification or (iii) elect for the Advance to be made
                     in accordance with the Request notwithstanding the event
                     specified in the notification. If any Borrower requires an
                     affected Advance to be made in the original currency
                     selected for such Advance notwithstanding the event
                     specified in the notification then within five Business
                     Days of receipt of the notification, the Company and the
                     Bank shall enter into negotiations for a period of not more
                     than 25 days with a view to agreeing a substitute basis for
                     determining the rate of interest and/or funding applicable
                     to the affected Advance and any


                                      -20-
<PAGE>   21

                     future Advances in the currency of the affected Advance
                     provided that if no substitute basis is agreed within that
                     period:

                     (a)        the Bank shall certify to the Company (such
                                certificate to be conclusive) the alternative
                                interest rate calculated in accordance with
                                sub-Clause 12.2.4 below;

                     (b)        the certificate may make provision for different
                                funding periods and shall be retroactive to the
                                beginning of the then current Term; and

                     (c)        the certificate shall be binding on each
                                relevant Borrower unless the Company gives
                                notice to the Bank within five Business Days of
                                the receipt of the certificate that the
                                certificate is not acceptable and that each
                                relevant Borrower shall prepay in full the
                                relevant Advances on a Business Day specified in
                                the notice, which shall be not less than five
                                nor more than thirty days after the date of the
                                Bank's certificate to the Company; and

           12.2.4     for the purposes of sub-Clause 12.2.3(a) above the rate of
                      interest on each Advance shall be the rate certified by
                      the Bank as the rate per annum determined by the Bank to
                      be the aggregate of:

                      (a)       the Margin;

                      (b)       the rate notified by the Bank, on or before the
                                last day of its Term, as being the cost to the
                                Bank of funding the Advance from such other
                                sources as it may reasonably select; and

                      (c)       the applicable Mandatory Cost if any.

12.3       During the period when any substitute basis is in force in relation
           to a particular currency, the Bank shall periodically determine
           whether the circumstances referred to in Clause 12.1 above still
           apply and, if they do not, shall forthwith give notice in writing to
           the Company of the date on which the substitute basis will cease to
           apply.

13.        INCREASED COSTS

           INCREASED COSTS - SERVICE OF DEMAND

13.1       If the result of any introduction of or change in any law or
           regulation after the Signing Date, or of any change in the
           application or interpretation of any such changed law or regulation
           or compliance by the Bank with any such changed law or regulation
           after the Signing Date (including, without limitation, any law or
           regulation relating to taxation, any reserve, special deposit, cash
           ratio, liquidity or capital adequacy requirement or any form of
           banking or monetary control but excluding (i) changes arising from
           the implementation by any authority having jurisdiction over the Bank
           or its holding company of the matters set out in the statement
           prepared by the Basle Committee on Banking Regulations and
           Supervisory Practices dated July 1988 and entitled



                                      -21-

<PAGE>   22


         "International Convergence of Capital Measurement and Capital
         Standards" (as amended in November 1991) and (ii) changes arising from
         the implementation in whole or in part by any authority having
         jurisdiction over the Bank or its holding company of the proposals
         contained in the matters set out in the EC Directive 93/6/EEC of 15
         March 1993 on the capital adequacy of investment firms and credit
         institutions) is that the Bank incurs an increased cost, then the Bank
         will promptly notify the Company of the relevant event and the Company
         shall on demand pay to the Bank such amount as the Bank certifies in
         the demand will compensate it for the applicable increased cost.

13.2     In this Clause 13 "INCREASED COST" means:

         13.2.1    an additional cost incurred by the Bank as a result of it
                   having entered into, or performing, maintaining or funding
                   its obligations under, this Agreement; or

         13.2.2    that portion of an additional cost incurred by the Bank in
                   making, funding or maintaining all or any advances comprised
                   in a class of advances formed by or including the Advances
                   made or to be made by it under this Agreement as is
                   attributable to it making, funding, or maintaining such
                   advances; or

         13.2.3    a reduction in any amount payable to the Bank or the
                   effective return to the Bank under this Agreement or on its
                   capital; or

         13.2.4    any payment made or interest or other return on or calculated
                   by reference to any amount received or receivable by the Bank
                   under this Agreement which is forgone.

13.3     When calculating an increased cost, the Bank may allocate or spread
         costs, liabilities and losses to or across its liabilities or assets,
         or any class of liabilities or assets, and on such basis, as it
         reasonably considers appropriate.

         INCREASED COSTS - EXCEPTIONS

13.4     An increased cost does not include any increased cost:

         13.4.1    compensated for by the payment of the Mandatory Cost;

         13.4.2    compensated for by the operation of Clause 11 (Taxes);

         13.4.3    attributable to any change in the rate of tax on the overall
                   net income of the Bank (or the overall net income of a
                   division or branch of the Bank) imposed in the jurisdiction
                   in which its principal office or the relevant lending office
                   for the time being is situate;

         13.4.4    payable to an assignee or transferee of the Bank at the time
                   of an assignment, transfer or novation under Clause 25
                   (Changes to the Parties), but only to the extent that the
                   increased cost would not have been payable to the assigning,
                   transferring or novating Bank; or

                                      -22-
<PAGE>   23

         13.4.5    which is attributable to the introduction of the euro other
                   than an increased cost which is being incurred generally by
                   banks transacting euro business in the London interbank
                   market.

14.      ILLEGALITY

14.1     If it is or becomes unlawful for the Bank to give effect to any of its
         obligations as contemplated by this Agreement or to fund or maintain
         any Advance, then the Bank shall notify the Company accordingly and on
         the Maturity Date of each relevant Advance (or such earlier date as the
         relevant law or directive may require) the relevant Borrower shall
         repay or prepay, as the case may be, any Advances made to it by the
         Bank together with all other amounts payable by it to the Bank under
         this Agreement.

14.2     The Bank's Commitment shall be cancelled on the date of a notification
         under Clause 14.1 above.

15.      TAXES AND INCREASED COSTS - ADDITIONAL RIGHTS

         PREPAYMENT AND CANCELLATIONS

15.1     If any Borrower is required to pay any additional amounts to the Bank
         under Clause 11 (Taxes) or compensation under Clause 13 (Increased
         Costs), the Company may, whilst the circumstances giving rise to the
         requirement continue, serve a notice of prepayment and cancellation in
         relation to all or all affected Advances on the Bank.

15.2     On the tenth Business Day after the date of service of the notice the
         relevant Borrower shall prepay the relevant Advance or Advances made to
         it by the Bank together with all other amounts in relation to such
         Advance(s) payable by it to the Bank under this Agreement.

15.3     To the extent of the Advances referred to in the notice of prepayment
         and cancellation, but not further or otherwise, the Bank's Commitment
         shall be cancelled on the date of service of the notice.

         MITIGATION

15.4     If, in respect of the Bank, circumstances arise which would or would,
         with the giving of notice, result in:

         15.4.1    any additional amounts becoming payable under Clause 11
                   (Taxes); or

         15.4.2    any increased cost becoming payable under Clause 13
                   (Increased Costs); or

         15.4.3    any prepayment, payment or cancellation under Clause 14
                   (Illegality),

         then the Bank shall endeavour to take such steps as are reasonably open
         to it to mitigate or remove those circumstances (including seeking
         recovery for the account of the relevant Borrower where reasonably
         practicable and/or


                                      -23-
<PAGE>   24

         transferring its rights and obligations under this Agreement to another
         bank or financial institution acceptable to the Company).

15.5     Clause 15.4 above does not:

         15.5.1    prejudice the obligations of any Borrower under this
                   Agreement (including, without limitation, under the Clauses
                   referred to in Clause 15.4 above); or

         15.5.2    require the Bank to take any action which, in its opinion,
                   might be in any way prejudicial to it or conflict with its

                   each Borrower under or pursuant to this Agreement becoming
                   void, voidable, unenforceable or ineffective as against each
                   such Borrower for any reason whatsoever, whether or not known
                   to the Bank, the amount of such loss being the amount which
                   the person or persons suffering it would otherwise have been

                   hereunder; or

         22.7.7    any other act, event or omission including, (without
                   limitation, any amendment to this Agreement) which, but for
                   this Clause 22.7 might operate to discharge, impair or
                   otherwise affect any of the obligations of the Borrowers or

         consent not to be unreasonably withheld or delayed) any other
         Subsidiary of the Company


                                      -38-
<PAGE>   39

         becomes an Acceding Borrower by delivering or procuring the delivery to
         the Bank a Borrower's Accession Notice duly executed by the Company and
         the relevant Subsidiary provided that if such Subsidiary is not
         resident in the United Kingdom for tax purposes the Company and the
         Bank agree to make such amendments to this Agreement as may be
         reasonably required at the time in order to allow such Subsidiary to
         pay interest to the Bank without deduction or withholding of any
         Relevant Tax and to provide such Subsidiary with equivalent rights,
         mutatis mutandis, to those contained in Clause 11.4 (Qualifying Bank).

31.2     Upon delivery of a Borrower's Accession Notice, the relevant Subsidiary
         shall become an Acceding Borrower and shall, subject to the terms and
         conditions of this Agreement acquire all the rights and assume all the
         obligations of a Borrower hereunder provided that the Bank has
         confirmed to the Company that it has received, in form and substance
         satisfactory to it, all the documents set out in Part II of Schedule 1.

31.3     The Company undertakes that it shall procure that each Acceding
         Borrower shall provide the Bank with each of the documents listed in
         Part II of Schedule 1.

31.4     If at any time any Borrower (other than the Company) has no actual or
         contingent obligation under this Agreement, the Company may deliver a

         shall forthwith cease to be a Borrower upon receipt by the Bank of such
         notice.

32.      CHANGE OF CURRENCY

32.1     If more than one currency or currency unit are at the same time

         that country, then:

         32.1.1    any reference in this Agreement to, and any obligations
                   arising under this Agreement in, the currency of that country
                   shall be translated into, or paid in, the currency unit of
                   that country designated by the Bank acting reasonably and in
                   consultation with the Company; and

         32.1.2    any translation from one currency unit to another shall be at
                   the official rate of exchange recognised by the relevant
                   central bank for the conversion of that currency or currency
                   unit into the other, rounded up or down by the Bank acting
                   reasonably.

32.2     If a change in any currency of a country occurs, the Bank and the
         Company will negotiate in good faith in order to agree any amendments
         to this Agreement to reflect market practice at that time with regard
         to the occurrence of EMU within the European Union or any part(s) of it
         and the new currency and to put the Bank and the Borrowers in the same
         position, so far as is possible, that they would have been in if no
         change in currency had occurred.

32.3     The Bank and the Company agree that the occurrence or non-occurrence of
         EMU within the European Union or part(s) of it and/or any event or
         events associated with EMU and/or the introduction of any new currency
         in all or any part of the European Union will not result in the
         discharge cancellation,

                                      -39-

34.      APPLICABLE LAW AND JURISDICTION

34.1     The law of England and Wales is the law applicable to this Agreement.

34.2     Each of the Borrowers irrevocably agrees for the benefit of the Bank
         that the courts of England shall have jurisdiction to hear and
         determine any suit, action or proceeding, and to settle any disputes,
         which may arise out of or in connection with this Agreement and, for
         such purposes, irrevocably submits to the jurisdiction of such courts.

34.3     Each of the Borrowers which is not incorporated in England and Wales
         agrees that the process by which any suit, action or proceeding is
         begun in England and Wales may be served on it by being delivered to
         the Company at its registered office for the time being and hereby
         appoints the Company (and the Company accepts such appointment) for
         such purposes. If the appointment of the person mentioned in this
         Clause 34.3 ceases to be effective in respect of any or all of the
         Borrowers such Borrower or Borrowers shall immediately appoint a
         further person in England and Wales to accept service of process on its
         behalf in England and Wales and, failing such appointment within
         fifteen days, the Bank acting reasonably shall be entitled to appoint
         such a person by notice to such Borrower or Borrowers. Nothing
         contained herein shall affect the right to serve process in any other
         manner permitted by law.

34.4     Each of the Borrowers irrevocably waives any objection which it might
         now or hereafter have to the courts referred to in Clause 34.2 being

2.         NATURE OF THE FACILITY

           FACILITY

2.1        The Bank grants to the Borrowers a revolving multi-currency advances
           facility under which the Bank shall, during the Availability Period
           and when requested by a Borrower, make to such Borrower Advances upon
           and subject to the terms of this Agreement.

           OVERALL FACILITY LIMIT

2.2        The aggregate Original Sterling Amount of all outstanding Advances
           shall not at any time exceed the Commitment at that time.

           NUMBER OF REQUESTS AND UTILISATIONS

2.3        Any number of Requests may be delivered on the same day and/or
           specifying the same Utilisation Date, whether or not the currencies
           and Terms requested are similar.

3.         PURPOSE

3.1        Each Borrower shall apply each Utilisation made to it towards the
           general corporate purposes of the Group.

3.2        Without affecting the obligations of any of the Borrowers in any way,
           the Bank shall not be bound to monitor or verify the application of
           the proceeds of any Utilisation.

4.         CONDITIONS PRECEDENT

           DOCUMENTARY CONDITIONS PRECEDENT

4.1        The obligations of the Bank to the Borrowers under this Agreement are
           subject to the condition precedent that the Bank has notified the
           Company that it has received, not later than 3 Business Days prior to
           the first Utilisation Date, all of the documents set out in Part I of
           Schedule 1 in form and substance satisfactory to the Bank.

           FURTHER CONDITIONS PRECEDENT

4.2        The obligation of the Bank to make each Utilisation is subject to the
           further conditions precedent that:


                                      -9-
<PAGE>   10

           4.2.1     on both the date of the Request and the Utilisation Date
                     for that Utilisation:

                     (a)    the representations and warranties in Clause 16
                            (Representations and Warranties) to be repeated on
                            those dates are correct and will be correct
                            immediately after the Utilisation; and

                     (b)    no Default is outstanding or might result from the
                            Utilisation; and

           4.2.2     the Utilisation would not cause Clause 2.2 (Overall
                     facility limit) to be contravened.

5.         THE FACILITY

           THE LOAN FACILITY

           RECEIPT OF REQUESTS FOR ADVANCES

5.1        Any Borrower may utilise the Facility if the Bank receives, not later
           than 10.00 a.m. on the Rate Fixing Day a duly completed Request,
           substantially in the form of Schedule 3 and signed by an Authorised
           Signatory of the relevant Borrower.

5.2        Any Borrower may utilise the Loan Facility by notifying the Bank by
           telephone not later than 10.00 a.m. on the Rate Fixing Day provided
           that a notice given by telephone shall be confirmed in writing by the
           delivery by the relevant Borrower to the Bank of a duly completed
           Request to be actually received by the Bank not later than the close
           of business in London on the day on which such telephone notice is,
           or is deemed to have been, given.

           COMPLETION OF REQUESTS

5.3        When giving a notice of Utilisation by telephone and when completing
           the Request, the relevant Borrower

           5.3.1     the Utilisation Date is a Business Day;

           5.3.2     only one currency is specified and that the Requested
                     Amount is:

                     (a)    if the currency is Sterling, a minimum
                            of Pound Sterling 1,000,000 and an integral multiple
                            of Pound Sterling 100,000; or

                     (b)    if the currency is Dollars, a minimum of US
                            $1,000,000 and an integral multiple of US $100,000;

                     (c)    if the currency is an Optional Currency other than
                            Dollars, a minimum and integral multiple of the
                            amounts agreed between the relevant Borrower and the
                            Bank before the telephone notice of Utilisation or
                            delivery of that Request; or


                                      -10-
<PAGE>   11

                     (d)    such other amounts as the Bank and the relevant
                            Borrower may agree;

           5.3.3     only one Term is specified which:

                     (a)    does not overrun the Final Maturity Date; and

                     (b)    is a period of an approved duration or of an
                            optional duration; and

           5.3.4     the payment instructions comply with Clause 9 (Payments).

           In this Clause:

           "APPROVED DURATION" means a period of 1, 2, 3 or 6 months; and

           "OPTIONAL DURATION" means any other period not exceeding 12 months.

           SELECTION OF TERM OF OPTIONAL DURATION

5.4        If the relevant Borrower selects a Term of an optional duration, it
           may also select at the time of the telephone notice of Utilisation
           and in the relevant Request a Term of any approved duration to apply
           if the selection of a Term of an optional duration becomes
           ineffective in accordance with Clause 5.5.2.

5.5        If:

           5.5.1     the relevant Borrower requests a Term of an optional
                     duration; and

           5.5.2     the Bank notifies such Borrower not later than 10.30 a.m.
                     on the date of receipt by it of the relevant Request or
                     telephone notice of Utilisation pursuant to Clause 5.1 or
                     Clause 5.2 respectively that it does not agree to that
                     request,

           the Term for the proposed Utilisation shall be the alternative period
           specified in the telephone notice of Utilisation or the relevant
           Request or, in the absence of any alternative selection, 3 months.

           PAYMENT OF PROCEEDS

<PAGE>   12

          VOLUNTARY CANCELLATION

           6.3.1     the date on which the cancellation is to become effective;
                     and

           6.3.2     the amount of the Commitment to be cancelled.

6.4        Any cancellation may only take effect in respect of the unutilised
           portion of the Commitment as at the date the notice is to be
           effective.

           NO REINSTATEMENT

6.5        No amount of the Commitment cancelled under this Agreement may
           subsequently be reinstated.

7.         INTEREST

           INTEREST RATE

7.1        The rate of interest on each Advance for its Term is the rate per
           annum determined by the Bank to be the aggregate of the applicable:

           7.1.1     Margin,

           7.1.2     LIBOR; and

           7.1.3     Mandatory Costs.

           DUE DATES

7.2        Except as otherwise provided in this Agreement, accrued interest on
           each Advance is payable on its Maturity Date and also, in the case of
           an Advance with a term longer than six months, on the date falling
           six months after its Utilisation Date.

           DEFAULT INTEREST

7.3        If any Borrower fails to pay any amount payable by it under this
           Agreement, it shall, on demand by the Bank from time to time, pay
           interest on the overdue amount from the due date up to the date of
           actual payment, after as well as before judgment, at a rate (the
           "DEFAULT RATE") determined by the Bank to be one (1) per cent. per
           annum above the higher of:

           7.3.1     the rate on the overdue amount under Clause 7.1 (Interest
                     rate) immediately before the due date (but only if the
                     overdue amount is an Advance (or part thereof) and only for
                     the period up to and including the Maturity Date of that
                     Advance); and

                                      -12-
<PAGE>   13


           7.3.2     the rate which would have been payable if the overdue
                     amount had, during the period of non-payment, constituted
                     an Advance in the currency of the overdue amount for such
                     successive Terms of such duration (not exceeding three
                     months) as the Bank may reasonably determine (each a
                     "DESIGNATED TERM").

7.4        The default rate will be determined on the first day of, or two
           Business Days before the first day of, the relevant Designated Term,
           as appropriate.

7.5        If the Bank determines that deposits in the currency of the overdue
           amount are not at the relevant time being made available by leading
           banks in the London Interbank Market, the default rate will be
           determined by reference to the cost of funds to the Bank from
           whatever sources it may reasonably select.

7.6        Default interest shall be compounded at the end of each Designated
           Term until it is paid.

           NOTIFICATION OF RATES OF INTEREST

7.7        The Bank shall promptly notify the relevant Borrower of the
           determination of any applicable rate of interest under this
           Agreement.

8.         REPAYMENT AND PREPAYMENT

           REPAYMENT OF ADVANCES

8.1        Each Borrower shall repay each Advance made to it in full on its
           Maturity Date to the Bank. If an Advance (the "NEW ADVANCE") is to be
           made to a Borrower on the day on which another Advance (the "MATURING
           ADVANCE") in the same currency is due to be repaid by such Borrower
           then, subject to the terms of this Agreement and so long as the
           conditions referred to in Clause 4.2 shall have been satisfied in
           relation to the New Advance:

           8.1.1     the Maturing Advance shall be deemed to have been repaid on
                     its Maturity Date either in whole (if the New Advance is
                     equal to or greater than the Maturing Advance) or in part
                     (if the New Advance is less than the Maturing Advance); and

           8.1.2     to the extent that a Maturing Advance is so deemed to have
                     been repaid, the principal amount of the New Advance to be
                     made on such a date shall be deemed to have been credited
                     to the account of such Borrower by the Bank in accordance
                     with the terms of this Agreement and, as the case may be:

                     (a)    the Bank shall only be obliged to make available to
                            such Borrower pursuant to Clause 5.6 a principal
                            amount equal to the amount (if any) by which the New
                            Advance exceeds the Maturing Advance; or

                     (b)    such Borrower shall only be obliged to pay to the
                            Bank pursuant to this Clause 8.1 a principal amount
                            equal to the


                                      -13-
<PAGE>   14
           amount by which the Maturing Advance exceeds the New Advance.

8.2        On the Final Maturity Date, all outstanding Advances and other sums
           (if any) then owing under this Agreement shall in any event be repaid
           or paid in full.

           PREPAYMENT OF ADVANCES

8.3        Any Borrower may, without penalty and on giving not less than 15
           days' prior notice to the Bank, prepay all or any part of an Advance,
           but if in part, in a minimum amount of Pound Sterling 1,000,000 and
           an integral multiple of Pound Sterling 100,000 (or the comparable
           amount in any Optional Currency).

8.4        Any notice by a Borrower of prepayment under this Agreement is
           irrevocable.

8.5        Should any person or group of persons, acting either individually or
           in concert (as defined in the City Code on Take Overs and Mergers
           effective as at the date of this Agreement) otherwise than with the
           consent of the Bank acquire control of the Company (and for the
           purpose of this Clause a single person or group of persons shall have
           acquired control if it or they own or hold more than 50% (fifty per
           cent.) of the issued share capital of the Company having the right to
           attend and vote at general meetings of the Company or more than 50%
           (fifty per cent.) of such rights), then:

           8.5.1     the Company shall immediately upon becoming aware thereof
                     notify the Bank specifying the date of such acquisition and
                     the name of such person or persons acquiring control; and

           8.5.2     thereafter no Borrower shall be permitted to request an
                     Advance unless the terms of the acquisition of control of
                     the Company were approved by the Board of Directors of the
                     Company and the Maturity Date for any Advance requested
                     falls on a date not more than three months after the
                     expiration of the 30 day period referred to in Clause 8.6.

8.6        If the terms of the acquisition of control of the Company were
           approved by the Board of Directors of the Company, the Bank shall
           consult with the Company during the period of 30 days after receipt
           of the notification from the Company referred to in sub-Clause 8.5.1
           and shall be entitled to give notice of continuance of the Facility
           provided hereunder to the Company. Upon receipt of such notice of
           continuance, the right of the Borrowers to request an Advance without
           the limitation referred to in sub-Clause 8.5.2 shall be reinstated.

8.7        If the terms of the acquisition of control of the Company were
           approved by the Board of Directors of the Company but, at the end of
           the period of 30 days referred to in Clause 8.6 above, the Company
           has not received a notice of continuance then:

           8.7.1     the Facility shall be cancelled;

           8.7.2     any outstanding Advances with Maturity Dates falling later
                     than three months after the end of such period shall be
                     prepaid on the date


                                      -14-

                     falling three months after the end of such period, together
                     with accrued interest thereon up to the date of payment and
                     all other amounts payable to the Bank hereunder; and

           8.7.3     any outstanding Advances with Maturity Dates falling not
                     later than three months after the end of such period shall
                     be repaid on their respective Maturity Dates.

8.8        If the terms of the acquisition of control of the Company were not
           approved by the Board of Directors of the Company, then unless the
           Bank shall have confirmed within 2 days of receipt of the notice
           referred to in sub-Clause 8.5.1 that the Facility shall be continued,
           the Facility shall be cancelled and any outstanding Advances shall be
           repayable on demand by the Bank together with accrued interest
           thereon up to the date of payment and all other amounts payable to
           the Bank hereunder.

8.9        Any prepayment under this Agreement shall be made together with
           accrued interest on the amount prepaid together with any amount
           payable to the Bank pursuant to Clause 22.3.

8.10       No Advance may be prepaid otherwise than in accordance with the
           express terms of this Agreement.

9.         PAYMENTS

           PLACE

9.1        All payments by each of the Borrowers or the Bank under this
           Agreement shall be made to such account at such office or bank in the

           the other or to such other place as may be agreed between the parties
           for this purpose.

           CURRENCY

           Subject to clauses 9.6 and 9.7:

9.3        A repayment or prepayment of an Advance is payable in the currency in
           which the Advance is denominated.

9.4        Interest is payable in the currency in which the relevant amount in
           respect of which it is payable is denominated.

9.5        Any other amount payable under this Agreement is, except as otherwise
           provided in this Agreement, payable in Sterling.

9.6        Subject to clause 9.7, on and after the Commencement Date, any
           Advance requested to be denominated in the currency of a
           Participating Member State shall be made in the euro unit.

9.7        If and to the extent that any EMU legislation provides that an amount
           denominated either in the euro unit or in the national currency unit
           of a given Participating Member State and payable within that
           Participating Member State by crediting an account of the creditor,
           can be paid by the debtor either in the euro unit or in that national
           currency unit, a Party shall be entitled to pay that amount either in
           the euro unit or in the relevant national currency unit.

           SET-OFF AND COUNTERCLAIM

9.8        All payments made by each of the Borrowers under this Agreement shall
           be made without set-off or counterclaim.

           NON-BUSINESS DAYS

9.9        If a payment under this Agreement is due on a day which is not a
           Business Day, then the due date for the payment shall instead be the
           next Business Day.

9.10       During any extension of the due date for payment of any principal
           under this Agreement pursuant to Clause 9.9 above interest is payable
           on the principal at the rate payable on the original due date.

           PARTIAL PAYMENTS

9.11       If the Bank receives a payment insufficient to discharge all the
           amounts then due and payable by any Borrower under this Agreement,
           the Bank shall apply that payment towards the obligations of such
           Borrower under this Agreement in the following order:

           9.11.1    firstly, in or towards payment of any unpaid costs and
                     expenses of the Bank under this Agreement;

           9.11.2    secondly, in or towards payment of any accrued fees due but
                     unpaid under Clause 19.2 (Commitment Fee);

           9.11.3    thirdly, in or towards payment of any accrued interest due
                     but unpaid under this Agreement;


                                      -16-
<PAGE>   17

           9.11.4    fourthly, in or towards payment of any principal due but
                     unpaid under this Agreement, and

           9.11.5    fifthly, in or towards payment of any other sum due but
                     unpaid under this Agreement.

9.12       The Bank may vary the order set out in Clauses 9.11.1 to 9.11.5 above

9.13       Clauses 9.11 and 9.12 above shall override any appropriation made by
           any Borrower.

10.        OPTIONAL CURRENCIES

           SELECTION

10.1       No Borrower may request an Advance denominated in an Optional
           Currency unless the Bank has confirmed to such Borrower that the
           Optional Currency is readily available and freely transferable in the
           London foreign exchange market.

           CHANGE OF CURRENCY

10.2       If, on the Rate Fixing Day of an Advance to be denominated in an
           Optional Currency, the Bank determines that:

           10.2.1    it is impracticable for reasons beyond its control for the
                     Bank to fund the Advance for its Term in that Optional
                     Currency in the ordinary course of business in the London
                     Interbank Market; or

           10.2.2    the use of the proposed Optional Currency might contravene
                     any law or regulation,

           then:

           10.2.3    the Bank shall promptly and in any event before 10.30 a.m.
                     on that Rate Fixing Day notify the relevant Borrower;

           10.2.4    if the Bank receives notice from the relevant Borrower by
                     11.30 a.m. on that Rate Fixing Day to that effect, the
                     Advance will not be made; and

           10.2.5    if the Bank does not receive any notice under sub-Clause
                     10.2.4 above, the Advance will be denominated instead in
                     Sterling in an amount equal to its Original Sterling
                     Amount.

           NOTIFICATION OF RATES AND AMOUNTS

10.3       The Bank shall, on request, promptly notify the relevant Borrower of
           any applicable Bank's Spot Rate of Exchange or Original Sterling
           Amount promptly after it has been ascertained.

10.4       If an Advance which has been drawn in an Optional Currency is
           reborrowed in the same Optional Currency immediately following its
           repayment, then the




                                      -17-
<PAGE>   18
           Original Sterling Amount of such new Advance denominated in such
           Optional Currency shall be recalculated for the new Term in
           accordance with the terms and conditions of this Agreement and if on
           the relevant Utilisation Date the aggregate Original Sterling Amount
           of all Advances outstanding on such date exceeds the Commitment, then
           any excess shall be repaid to the Bank by the relevant Borrower upon
           the Bank's first written demand.


11.        TAXES

           GROSS-UP

11.1       All payments by each of the Borrowers under this Agreement shall be
           made without any deductions and free and clear of and without
           deduction for or on account of any Relevant Taxes except to the
           extent that any Borrower is required by law to make payment subject
           to any such taxes. If any Relevant Tax or amounts in respect of any
           Relevant Tax must be deducted from any amounts payable or paid by any
           Borrower hereunder, such Borrower shall pay such additional amounts
           as may be necessary to ensure that the Bank receives a net amount
           equal to the full amount which it would have received had payment not
           been made subject to tax.

           "RELEVANT TAX" in relation to any payment which falls to be made
           hereunder means any present or future taxes of any nature now or
           hereafter imposed by the laws of (i) the United Kingdom, (ii) any
           other jurisdiction from which, or through which, such payment is made
           or to the taxation laws of which the relevant Borrower is at the time
           of such payment subject, (iii) any political sub-division of the
           United Kingdom or any such other jurisdiction or (iv) any federation
           or association of states of which the United Kingdom or any such
           other jurisdiction is, at the time of such payment, a member.

           TAX RECEIPTS

11.2       All Relevant Taxes required by law to be deducted or withheld by any
           Borrower from any amount paid or payable under this Agreement shall
           be paid by such Borrower when due (unless the obligation to pay is
           being disputed in good faith) and such Borrower shall, within 30 days
           of the payment being made, deliver to the Bank evidence satisfactory
           to the Bank (including all relevant tax receipts) that the payment
           has been duly remitted to the appropriate authority.

           TAX CREDITS

11.3       If any Borrower pays any additional amount (a "TAX PAYMENT") under
           Clause 11.1 and the Bank effectively obtains a refund of tax, or a
           relief or credit against tax by reason of that Tax Payment (a "TAX
           CREDIT"), and the Bank is able to identify the Tax Credit as being
           attributable to the Tax Payment, then the Bank shall reimburse to the
           relevant Borrower such amount as the Bank reasonably determines to be
           the proportion of the Tax Credit as will leave the Bank (after that
           reimbursement) in no better or worse position that it would have been
           if the Tax Payment had not been required. Nothing in this Clause
           interferes with the right of the Bank to arrange its tax affairs in
           whatever manner it thinks fit


                                   -18-
<PAGE>   19
           and, without prejudice to the foregoing, the Bank is under no
           obligation to claim a Tax Credit, or to claim a Tax Credit in
           priority to any other claim, relief, credit or deduction available to
           it. The Bank is not obliged to disclose any information regarding its
           tax affairs or computations to any Borrower.


           QUALIFYING BANK

11.4       If, otherwise than as a result of the introduction of, change in, or
           change in the interpretation, administration or application of, any
           law or regulation or any practice or concession of the Inland Revenue
           after the Signing Date, the Bank ceases to be a Qualifying Bank no
           Borrower shall be liable to pay to the Bank under Clause 11.1
           (Gross-up) any amount in respect of taxes levied or imposed by the UK
           or any taxing authority thereof or therein in excess of the amount it
           would have been obliged to pay if the Bank had been or had not ceased
           to be a Qualifying Bank.

12.        MARKET DISRUPTION

           MARKET DISRUPTION

12.1       If, in relation to any proposed Utilisation:

           12.1.1    the Bank is unable to obtain from leading banks a rate for
                     the purposes of determining the applicable LIBOR or the
                     Bank otherwise determines that adequate and fair means do
                     not exist for ascertaining the applicable LIBOR; or

           12.1.2    in the opinion of the Bank:

                     (a)    matching deposits may not be available to it in the
                            London Interbank Market in the ordinary course of
                            business to fund an Advance; or

                     (b)    the cost to it of matching deposits in the London
                            Interbank Market would be in excess of the relevant
                            LIBOR,

                     the Bank shall notify the Company by 10.30 a.m. or as soon
                     as is practicable thereafter on the Rate Fixing Day of the
                     fact and that this Clause is in operation.

12.2       After any notification under Clause 12.1 above:

           12.2.1    subject to sub-Clause 12.2.3 below the relevant Advance
                     shall be made in Sterling in an amount equal to its
                     Original Sterling Amount (unless Sterling was the original
                     currency of the relevant Advance);

           12.2.2    subject to sub-Clause 12.2.3 below, no further notices of
                     Utilisation by telephone or Requests for Advances to be
                     denominated in the original currency of the affected
                     Advance may be delivered until the Bank notifies the
                     Company that the event specified in the notification no
                     longer prevails;


                                      -19-
<PAGE>   20
           12.2.3   the relevant Borrower may, by notice to the Bank by 11.00
                    a.m. (or, if later, within 30 minutes of receipt by the
                    Company of a notification under sub-Clause 12.1.2) on the
                    Rate Fixing Day: (i) elect for the notice of Utilisation by
                    telephone or the Request to be cancelled without penalty;
                    (ii) if the Advance was to be made in an Optional Currency,
                    elect for the Advance to be made in an Optional Currency
                    other than a currency affected by the event specified in the
                    notification or (iii) elect for the Advance to be made in
                    accordance with the Request notwithstanding the event
                    specified in the notification. If any Borrower requires an
                    affected Advance to be made in the original currency
                    selected for such Advance notwithstanding the event
                    specified in the notification then within five Business Days
                    of receipt of the notification, the Company and the Bank
                    shall enter into negotiations for a period of not more than
                    25 days with a view to agreeing a substitute basis for
                    determining the rate of interest and/or funding applicable
                    to the affected Advance and any future Advances in the
                    currency of the affected Advance provided that if no
                    substitute basis is agreed within that period:




                    (a)     the Bank shall certify to the Company (such
                            certificate to be conclusive) the alternative
                            interest rate calculated in accordance with
                            sub-Clause 12.2.4 below;

                    (b)     the certificate may make provision for different
                            funding periods and shall be retroactive to the
                            beginning of the then current Term; and

                    (c)     the certificate shall be binding on each
                            relevant Borrower unless the Company gives
                            notice to the Bank within five Business Days of
                            the receipt of the certificate that the
                            certificate is not acceptable and that each
                            relevant Borrower shall prepay in full the
                            relevant Advances on a Business Day specified in

           12.2.4   for the purposes of sub-Clause 12.2.3(a) above the rate of
                    interest on each Advance shall be the rate certified by the
                    Bank as the rate per annum determined by the Bank to be the
                    aggregate of:

                    (a)     the Margin;

                    (b)     the rate notified by the Bank, on or before the
                            last day of its Term, as being the cost to the
                            Bank of funding the Advance from such other
                            sources as it may reasonably select; and

                    (c)     the applicable Mandatory Cost if any.

12.3       During the period when any substitute basis is in force in relation
           to a particular currency, the Bank shall periodically determine

           apply and, if they do not,

                                      -20-

           shall forthwith give notice in writing to the Company of the date on
           which the substitute basis will cease to apply.

13.        INCREASED COSTS

           INCREASED COSTS - SERVICE OF DEMAND

13.1       If the result of any introduction of or change in any law or
           regulation after the Signing Date, or of any change in the
           application or interpretation of any such changed law or regulation
           or compliance by the Bank with any such changed law or regulation
           after the Signing Date (including, without limitation, any law or
           regulation relating to taxation, any reserve, special deposit, cash
           ratio, liquidity or capital adequacy requirement or any form of
           banking or monetary control but excluding (i) changes arising from
           the implementation by any authority having jurisdiction over the Bank
           or its holding company of the matters set out in the statement
           prepared by the Basle Committee on Banking Regulations and
           Supervisory Practices dated July 1988 and entitled "International
           Convergence of Capital Measurement and Capital Standards" (as amended
           in November 1991) and (ii) changes arising from the implementation in
           whole or in part by any authority having jurisdiction over the Bank
           or its holding company of the proposals contained in the matters set
           out in the EC Directive 93/6/EEC of 15 March 1993 on the capital
           adequacy of investment firms and credit institutions) is that the
           Bank incurs an increased cost, then the Bank will promptly notify the
           Company of the relevant event and the Company shall on demand pay to
           the Bank such amount as the Bank certifies in the demand will
           compensate it for the applicable increased cost.

13.2       In this Clause 13 "INCREASED COST" means:

           13.2.1    an additional cost incurred by the Bank as a result of it
                     having entered into, or performing, maintaining or funding
                     its obligations under, this Agreement; or

           13.2.2    that portion of an additional cost incurred by the Bank in
                     making, funding or maintaining all or any advances
                     comprised in a class of advances formed by or including the
                     Advances made or to be made by it under this Agreement as
                     is attributable to it making, funding, or maintaining such
                     advances; or

           13.2.3    a reduction in any amount payable to the Bank or the
                     effective return to the Bank under this Agreement or on its
                     capital; or

           13.2.4    any payment made or interest or other return on or
                     calculated by reference to any amount received or
                     receivable by the Bank under this Agreement which is
                     forgone.

 13.3      When calculating an increased cost, the Bank may allocate or spread
           costs, liabilities and losses to or across its liabilities or assets,
           or any class of liabilities or assets, and on such basis, as it
           reasonably considers  appropriate.

           INCREASED COSTS - EXCEPTIONS

13.4       An increased cost does not include any increased cost:

           13.4.1    compensated for by the payment of the Mandatory Cost;

           13.4.2    compensated for by the operation of Clause 11 (Taxes);

           13.4.3    attributable to any change in the rate of tax on the
                     overall net income of the Bank (or the overall net income
                     of a division or branch of the Bank) imposed in the
                     jurisdiction in which its principal office or the relevant
                     lending office for the time being is situate;

           13.4.4    payable to an assignee or transferee of the Bank at the
                     time of an assignment, transfer or novation under Clause 25
                     (Changes to the Parties), but only to the extent that the
                     increased cost would not have been payable to the
                     assigning, transferring or novating Bank; or

           13.4.5    which is attributable to the introduction of the euro other
                     than an increased cost which is being incurred generally by
                     banks transacting euro business in the London interbank
                     market.

14.        ILLEGALITY

14.1       If it is or becomes unlawful for the Bank to give effect to any of
           its obligations as contemplated by this Agreement or to fund or
           maintain any Advance, then the Bank shall notify the Company
           accordingly and on the Maturity Date of each relevant Advance (or
           such earlier date as the relevant law or directive may require) the
           relevant Borrower shall repay or prepay, as the case may be, any
           Advances made to it by the Bank together with all other amounts
           payable by it to the Bank under this Agreement.

14.2       The Bank's Commitment shall be cancelled on the date of a
           notification under Clause 14.1 above.

15.        TAXES AND INCREASED COSTS - ADDITIONAL RIGHTS

           PREPAYMENT AND CANCELLATIONS

15.1       If any Borrower is required to pay any additional amounts to the Bank
           under Clause 11 (Taxes) or compensation under Clause 13 (Increased
           Costs), the Company may, whilst the circumstances giving rise to the
           requirement continue, serve a notice of prepayment and cancellation
           in relation to all or all affected Advances on the Bank.

15.2       On the tenth Business Day after the date of service of the notice the
           relevant Borrower shall prepay the relevant Advance or Advances made
           to it by the Bank together with all other amounts in relation to such
           Advance(s) payable by it to the Bank under this Agreement.

          and cancellation, but not further or otherwise, the Bank's Commitment
          shall be cancelled on the date of service of the notice.

          MITIGATION

15.4      If, in respect of the Bank, circumstances arise which would or would,
          with the giving of notice, result in:

          15.4.1   any additional amounts becoming payable under Clause 11
                   (Taxes); or

          15.4.2   any increased cost becoming payable under Clause 13
                   (Increased Costs); or

          15.4.3   any prepayment, payment or cancellation under Clause 14
                   (Illegality),

          then the Bank shall endeavour to take such steps as are reasonably
          open to it to mitigate or remove those circumstances (including
          seeking recovery for the account of the relevant Borrower where
          reasonably practicable and/or transferring its rights and obligations
          under this Agreement to another bank or financial institution
          acceptable to the Company).

15.5      Clause 15.4 above does not:

          15.5.1    prejudice the obligations of any Borrower under this
                    Agreement (including, without limitation, under the Clauses
                    referred to in Clause 15.4 above); or

          15.5.2    require the Bank to take any action which, in its opinion,
                    might be in any way prejudicial to it or conflict with its

18.        DEFAULT

           EVENTS OF DEFAULT

18.1       Each of the events set out in Clauses 18.2 to 18.13 (inclusive) is an
           Event of Default (whether or not caused by any reason whatsoever

           (inclusive) occurs in relation to a Material Subsidiary which is not
           a Borrower it will only be an Event of Default if the event is, in
           the reasonable opinion of the Bank, reasonably likely to affect
           materially and adversely the Company's ability to perform its
           obligations under this Agreement.

           NON-PAYMENT

18.2       Any Borrower defaults in payment on the due date of any amount

           reasonable opinion of the Bank, are not material), and (in the case
           of a breach capable of being remedied) fails to remedy the breach

31.        DESIGNATION OF ACCEDING AND SECEDING BORROWERS

31.1       The Company may request that any of its Subsidiaries incorporated in
           England and Wales and, with the prior written consent of the Bank
           (such consent not to be unreasonably withheld or delayed) any other
           Subsidiary of the Company becomes an Acceding Borrower by delivering
           or procuring the delivery to the


                                      -37-
<PAGE>   38

           Bank a Borrower's Accession Notice duly executed by the Company and
           the relevant Subsidiary provided that if such Subsidiary is not
           resident in the United Kingdom for tax purposes the Company and the
           Bank agree to make such amendments to this Agreement as may be
           reasonably required at the time in order to allow such Subsidiary to
           pay interest to the Bank without deduction or withholding of any
           Relevant Tax and to provide such Subsidiary with equivalent rights,
           mutatis mutandis, to those contained in Clause 11.4
           (Qualifying Bank).

31.2       Upon delivery of a Borrower's Accession Notice, the relevant
           Subsidiary shall become an Acceding Borrower and shall, subject to
           the terms and conditions of this Agreement acquire all the rights and
           assume all the obligations of a Borrower hereunder provided that the
           Bank has confirmed to the Company that it has received, in form and
           substance satisfactory to it, all the documents set out in Part II of
           Schedule 1.

31.3       The Company undertakes that it shall procure that each Acceding
           Borrower shall provide the Bank with each of the documents listed in
           Part II of Schedule 1.

31.4       If at any time any Borrower (other than the Company) has no actual or
           contingent obligation under this Agreement, the Company may deliver a
           Borrower's Cessation Notice to the Bank in which event such Borrower
           shall forthwith cease to be a Borrower upon receipt by the Bank of
           such notice.

32.        CHANGE OF CURRENCY

32.1       If more than one currency or currency unit are at the same time
           recognised by the central bank of any country as the lawful currency
           of that country, then:

           32.1.1    any reference in this Agreement to, and any obligations
                     arising under this Agreement in, the currency of that
                     country shall be translated into, or paid in, the currency
                     unit of that country designated by the Bank acting
                     reasonably and in consultation with the Company; and

           32.1.2    any translation from one currency unit to another shall be
                     at the official rate of exchange recognised by the relevant
                     central bank for the conversion of that currency or
                     currency unit into the other, rounded up or down by the
                     Bank acting reasonably.

32.2       If a change in any currency of a country occurs, the Bank and the
           Company will negotiate in good faith in order to agree any amendments
           to this Agreement to reflect market practice at that time with regard
           to the occurrence of EMU within the European Union or any part(s) of
           it and the new currency and to put the Bank and the Borrowers in the
           same position, so far as is possible, that they would have been in if
           no change in currency had occurred.

32.3       The Bank and the Company agree that the occurrence or non-occurrence
           of EMU within the European Union or part(s) of it and/or any event or
           events associated with EMU and/or the introduction of any new
           currency in all or any part of the European Union will not result in
           the discharge cancellation, rescission or termination in whole or in
           pat of this Agreement or give any party


                                      -38-
<PAGE>   39

           hereto the right to cancel, rescind, terminate or vary (other than as
           aforesaid) this Agreement in whole or in part or give rise to an
           Event of Default.

33.        COUNTERPARTS

           This Agreement may be executed in any number of counterparts each of
           which shall be an original and all of such counterparts taken
           together shall be delivered to constitute one and the same
           instrument.

34.        APPLICABLE LAW AND JURISDICTION

34.1       The law of England and Wales is the law applicable to this Agreement.

34.2       Each of the Borrowers irrevocably agrees for the benefit of the Bank
           that the courts of England shall have jurisdiction to hear and
           determine any suit, action or proceeding, and to settle any disputes,
           which may arise out of or in connection with this Agreement and, for
           such purposes, irrevocably submits to the jurisdiction of such
           courts.

34.3       Each of the Borrowers which is not incorporated in England and Wales
           agrees that the process by which any suit, action or proceeding is
           begun in England and Wales may be served on it by being delivered to
           the Company at its registered office for the time being and hereby
           appoints the Company (and the Company accepts such appointment) for
           such purposes. If the appointment of the person mentioned in this
           Clause 34.3 ceases to be effective in respect of any or all of the
           Borrowers such Borrower or Borrowers shall immediately appoint a
           further person in England and Wales to accept service of process on
           its behalf in England and Wales and, failing such appointment within
           fifteen days, the Bank acting reasonably shall be entitled to appoint
           such a person by notice to such Borrower or Borrowers. Nothing
           contained herein shall affect the right to serve process in any other
           manner permitted by law.

34.4       Each of the Borrowers irrevocably waives any objection which it might
           now or hereafter have to the courts referred to in Clause 34.2 being
           nominated as the forum to hear and determine any suit, action or
           proceeding, and to settle any disputes, which may arise out of or in
           connection with this Agreement and agrees not to claim that any such
           court is not a convenient or appropriate forum.

34.5       The submission to the jurisdiction of the courts referred to in
           Clause 34.2 shall not (and shall not be construed so as to) limit the
           right of the Bank to take proceedings against any of the Borrowers in
           any other court of competent jurisdiction nor shall the taking of
           proceedings in any one or more jurisdictions preclude the taking of
           proceedings in any other jurisdiction (whether concurrently or not)
           if and to the extent permitted by applicable law.

This Agreement has been entered into on the date stated at the beginning of this
Agreement.

                  that Utilisation:

                  (a)  the representations and warranties in Clause 16
                       (Representations and Warranties) to be repeated on those
                       dates are correct and will be correct immediately after
                       the Utilisation; and

                  (b)  no Default is outstanding or might result from the
                       Utilisation; and

         4.2.2    the Utilisation would not cause Clause 2.2 (Overall facility
                  limit) to be contravened.

         4.2.3    in the case of the first Utilisation either:

                  (a)  the total aggregate amounts outstanding under the
                       Revolving Multi-Currency Credit Facility Agreement dated
                       17th May 1993 (as amended) made between the Company and
                       the Bank the "Existing Outstandings", shall have been
                       repaid or prepaid in full and the aggregate commitments
                       under such facility agreement cancelled on the day of
                       such repayment or prepayment; or

                  (b)  the amount of the first Utilisation together with other
                       sums available to the Borrower shall be used to repay or
                       prepay the Existing Outstandings and the aggregate
                       commitments under such facility agreement cancelled on
                       the day of such repayment or prepayment.

<PAGE>   12

         the Bank not later than the close of business in London on the day on

         COMPLETION OF REQUESTS

5.3      When giving a notice of Utilisation by telephone and when completing
         the Request, the relevant Borrower must ensure that:

         5.3.1    the Utilisation Date is a Business Day;

         5.3.2    only one currency is specified and that the Requested Amount
                  is:

                  (a)  if the currency is Sterling, a minimum of Pound Sterling
                       1,000,000 and an integral multiple of Pound Sterling

                       agreed between the relevant Borrower and the Bank before
                       the telephone notice of Utilisation or delivery of that
                       Request; or

                  (d)  such other amounts as the Bank and the relevant Borrower
                       may agree;

         5.3.3    only one Term is specified which:

                  (a)  does not overrun the Final Maturity Date; and

                  (b)  is a period of an approved duration or of an optional
                       duration; and

         5.3.4    the payment instructions comply with Clause 9 (Payments).

         In this Clause:

         "APPROVED DURATION" means a period of 1, 2, 3 or 6 months; and

         "OPTIONAL DURATION" means any other period not exceeding 12 months.

         SELECTION OF TERM OF OPTIONAL DURATION

5.4      If the relevant Borrower selects a Term of an optional duration, it may
         also select at the time of the telephone notice of Utilisation and in
         the relevant Request a Term of any approved duration to apply if the
         selection of a Term of an optional duration becomes ineffective in
         accordance with Clause 5.5.2.

5.5      If:

         5.5.1    the relevant Borrower requests a Term of an optional duration;
                  and


<PAGE>   13

         5.5.2    the Bank notifies such Borrower not later than 10.30 a.m. on
                  the date of receipt by it of the relevant Request or telephone
                  notice of Utilisation pursuant to Clause 5.1 or Clause 5.2
                  respectively that it does not agree to that request,

         the Term for the proposed Utilisation shall be the alternative period
         specified in the telephone notice of Utilisation or the relevant
         Request or, in the absence of any alternative selection, 3 months.

         PAYMENT OF PROCEEDS

5.6      Subject to the terms of this Agreement, the Bank shall make the Advance
         available to the relevant Borrower on the relevant Utilisation Date.

6.       CANCELLATION

         AUTOMATIC CANCELLATION OF THE COMMITMENT

6.1      The Commitment shall be automatically cancelled at close of business on
         the Final Maturity Date.

         VOLUNTARY CANCELLATION

6.2      The Company may, without penalty and by giving not less than 15 days'
         prior notice to the Bank, cancel the Commitment in whole or in part.

6.3      A notice of cancellation will be irrevocable and shall specify:

         6.3.1    the date on which the cancellation is to become effective; and

         6.3.2    the amount of the Commitment to be cancelled.

6.4      Any cancellation may only take effect in respect of the unutilised
         portion of the Commitment as at the date the notice is to be effective.

         NO REINSTATEMENT

6.5      No amount of the Commitment cancelled under this Agreement may
         subsequently be reinstated.

7.       INTEREST

         INTEREST RATE

7.1      The rate of interest on each Advance for its Term is the rate per annum
         determined by the Bank to be the aggregate of the applicable:

         7.1.1    Margin,

         7.1.2    LIBOR; and



<PAGE>   14

         7.1.3    Mandatory Costs.

         DUE DATES

7.2      Except as otherwise provided in this Agreement, accrued interest on
         each Advance is payable on its Maturity Date and also, in the case of
         an Advance with a term longer than six months, on the date falling six
         months after its Utilisation Date.

         DEFAULT INTEREST

7.3      If any Borrower fails to pay any amount payable by it under this
         Agreement, it shall, on demand by the Bank from time to time, pay
         interest on the overdue amount from the due date up to the date of
         actual payment, after as well as before judgment, at a rate (the
         "DEFAULT RATE") determined by the Bank to be one (1) per cent. per
         annum above the higher of:

         7.3.1    the rate on the overdue amount under Clause 7.1 (Interest
                  rate) immediately before the due date (but only if the overdue
                  amount is an Advance (or part thereof) and only for the period
                  up to and including the Maturity Date of that Advance); and

         7.3.2    the rate which would have been payable if the overdue amount
                  had, during the period of non-payment, constituted an Advance
                  in the currency of the overdue amount for such successive
                  Terms of such duration (not exceeding three months) as the
                  Bank may reasonably determine (each a "DESIGNATED TERM").

7.4      The default rate will be determined on the first day of, or two
         Business Days before the first day of, the relevant Designated Term, as
         appropriate.

7.5      If the Bank determines that deposits in the currency of the overdue
         amount are not at the relevant time being made available by leading
         banks in the London Interbank Market, the default rate will be
         determined by reference to the cost of funds to the Bank from whatever
         sources it may reasonably select.

7.6      Default interest shall be compounded at the end of each Designated Term
         until it is paid.

         NOTIFICATION OF RATES OF INTEREST

7.7      The Bank shall promptly notify the relevant Borrower of the
         determination of any applicable rate of interest under this Agreement.

8.       REPAYMENT AND PREPAYMENT

         REPAYMENT OF ADVANCES

8.1      Each Borrower shall repay each Advance made to it in full on its
         Maturity Date to the Bank. If an Advance (the "NEW ADVANCE") is to be
         made to a Borrower on the day on which another Advance (the "MATURING
         ADVANCE")

<PAGE>   15


         in the same currency is due to be repaid by such Borrower then, subject
         to the terms of this Agreement and so long as the conditions referred
         to in Clause 4.2 shall have been satisfied in relation to the New
         Advance:

         8.1.1    the Maturing Advance shall be deemed to have been repaid on
                  its Maturity Date either in whole (if the New Advance is equal
                  to or greater than the Maturing Advance) or in part (if the
                  New Advance is less than the Maturing Advance); and

         8.1.2    to the extent that a Maturing Advance is so deemed to have
                  been repaid, the principal amount of the New Advance to be
                  made on such a date shall be deemed to have been credited to
                  the account of such Borrower by the Bank in accordance with
                  the terms of this Agreement and, as the case may be:

                  (a)  the Bank shall only be obliged to make available to such
                       Borrower pursuant to Clause 5.6 a principal amount equal
                       to the amount (if any) by which the New Advance exceeds
                       the Maturing Advance; or

                  (b)  such Borrower shall only be obliged to pay to the Bank
                       pursuant to this Clause 8.1 a principal amount equal to
                       the amount by which the Maturing Advance exceeds the New
                       Advance.

8.2      On the Final Maturity Date, all outstanding Advances and other sums (if
         any) then owing under this Agreement shall in any event be repaid or
         paid in full.

         PREPAYMENT OF ADVANCES

8.3      Any Borrower may, without penalty and on giving not less than 15 days'
         prior notice to the Bank, prepay all or any part of an Advance, but if
         in part, in a minimum amount of Pound Sterling 1,000,000 and an
         integral multiple of Pound Sterling 100,000 (or the comparable amount
         in any Optional Currency).

8.4      Any notice by a Borrower of prepayment under this Agreement is
         irrevocable.

8.5      Should any person or group of persons, acting either individually or in
         concert (as defined in the City Code on Take Overs and Mergers
         effective as at the date of this Agreement) otherwise than with the
         consent of the Bank acquire control of the Company (and for the purpose
         of this Clause a single person or group of persons shall have acquired
         control if it or they own or hold more than 50% (fifty per cent.) of
         the issued share capital of the Company having the right to attend and
         vote at general meetings of the Company or more than 50% (fifty per
         cent.) of such rights), then:

         8.5.1    the Company shall immediately upon becoming aware thereof
                  notify the Bank;

         8.5.2    whereupon, unless the Bank otherwise agrees, the Facility
                  shall be cancelled and all outstanding Advances shall be
                  repaid on or before


<PAGE>   16

                  the date falling 30 days after the date the Bank receives the
                  notification from the Company referred to in sub-clause 8.5.1
                  together with accrued interest thereon up to the date of
                  payment and all other amounts payable to the Bank hereunder.


8.6      Any prepayment under this Agreement shall be made together with accrued
         interest on the amount prepaid together with any amount payable to the
         Bank pursuant to Clause 22.3.

8.7      No Advance may be prepaid otherwise than in accordance with the express
         terms of this Agreement.

9.       PAYMENTS

         PLACE

9.1      All payments by each of the Borrowers or the Bank under this Agreement
         shall be made to such account at such office or bank in the principal

         to such other place as may be agreed between the parties for this
         purpose.

                  funds;

         9.2.3    if in an Optional Currency (other than Dollars) in the place
                  for payment on the due date in lawful money of the country of
                  that Optional Currency, in immediately available funds, or at
                  such times or in such funds as the Bank may specify to the
                  relevant Borrower as being customary at the time for the
                  settlement of transactions in the relevant currency in the
                  place for payment.

         CURRENCY

         Subject to clauses 9.6 and 9.7:

9.3      A repayment or prepayment of an Advance is payable in the currency in
         which the Advance is denominated.

9.4      Interest is payable in the currency in which the relevant amount in
         respect of which it is payable is denominated.

9.5      Any other amount payable under this Agreement is, except as otherwise
         provided in this Agreement, payable in Sterling.



<PAGE>   17
9.6      Subject to clause 9.7, on and after the Commencement Date, any Advance
         requested to be denominated in the currency of a Participating Member
         State shall be made in the euro unit.

9.7      If and to the extent that any EMU legislation provides that an amount
         denominated either in the euro unit or in the national currency unit of
         a given Participating Member State and payable within that
         Participating Member State by crediting an account of the creditor, can
         be paid by the debtor either in the euro unit or in that national
         currency unit, a Party shall be entitled to pay that amount either in
         the euro unit or in the relevant national currency unit.

         SET-OFF AND COUNTERCLAIM

9.8      All payments made by each of the Borrowers under this Agreement shall
         be made without set-off or counterclaim.

         NON-BUSINESS DAYS

9.9      If a payment under this Agreement is due on a day which is not a
         Business Day, then the due date for the payment shall instead be the
         next Business Day.

9.10     During any extension of the due date for payment of any principal under
         this Agreement pursuant to Clause 9.9 above interest is payable on the
         principal at the rate payable on the original due date.

         PARTIAL PAYMENTS

9.11     If the Bank receives a payment insufficient to discharge all the
         amounts then due and payable by any Borrower under this Agreement, the
         Bank shall apply that payment towards the obligations of such Borrower
         under this Agreement in the following order:

         9.11.1   firstly, in or towards payment of any unpaid costs and
                  expenses of the Bank under this Agreement;

         9.11.2   secondly, in or towards payment of any accrued fees due but
                  unpaid under Clause 19.2 (Commitment Fee);

         9.11.3   thirdly, in or towards payment of any accrued interest due but
                  unpaid under this Agreement;

         9.11.4   fourthly, in or towards payment of any principal due but
                  unpaid under this Agreement, and

         9.11.5   fifthly, in or towards payment of any other sum due but unpaid
                  under this Agreement.

9.12     The Bank may vary the order set out in Clauses 9.11.1 to 9.11.5 above.

         any Borrower.


<PAGE>   18

10.      OPTIONAL CURRENCIES

         SELECTION

10.1     No Borrower may request an Advance denominated in an Optional Currency
         unless the Bank has confirmed to such Borrower that the Optional
         Currency is readily available and freely transferable in the London
         foreign exchange market.

         CHANGE OF CURRENCY

10.2     If, on the Rate Fixing Day of an Advance to be denominated in an
         Optional Currency, the Bank determines that:

         10.2.1   it is impracticable for reasons beyond its control for the
                  Bank to fund the Advance for its Term in that Optional
                  Currency in the ordinary course of business in the London
                  Interbank Market; or

         10.2.2   the use of the proposed Optional Currency might contravene any
                  law or regulation,
         then:

         10.2.3   the Bank shall promptly and in any event before 10.30 a.m. on
                  that Rate Fixing Day notify the relevant Borrower;

         10.2.4   if the Bank receives notice from the relevant Borrower by
                  11.30 a.m. on that Rate Fixing Day to that effect, the Advance
                  will not be made; and

         10.2.5   if the Bank does not receive any notice under sub-Clause
                  10.2.4 above, the Advance will be denominated instead in
                  Sterling in an amount equal to its Original Sterling Amount.

         NOTIFICATION OF RATES AND AMOUNTS

10.3     The Bank shall, on request, promptly notify the relevant Borrower of
         any applicable Bank's Spot Rate of Exchange or Original Sterling Amount
         promptly after it has been ascertained.

10.4     If an Advance which has been drawn in an Optional Currency is
         reborrowed in the same Optional Currency immediately following its
         repayment, then the Original Sterling Amount of such new Advance
         denominated in such Optional Currency shall be recalculated for the new
         Term in accordance with the terms and conditions of this Agreement and
         if on the relevant Utilisation Date the aggregate Original Sterling
         Amount of all Advances outstanding on such date exceeds the Commitment,
         then any excess shall be repaid to the Bank by the relevant Borrower
         upon the Bank's first written demand.


<PAGE>   19

11.      TAXES

         GROSS-UP

11.1     All payments by each of the Borrowers under this Agreement shall be
         made without any deductions and free and clear of and without deduction
         for or on account of any Relevant Taxes except to the extent that any
         Borrower is required by law to make payment subject to any such taxes.
         If any Relevant Tax or amounts in respect of any Relevant Tax must be
         deducted from any amounts payable or paid by any Borrower hereunder,
         such Borrower shall pay such additional amounts as may be necessary to
         ensure that the Bank receives a net amount equal to the full amount
         which it would have received had payment not been made subject to tax.

         "RELEVANT TAX" in relation to any payment which falls to be made
         hereunder means any present or future taxes of any nature now or
         hereafter imposed by the laws of (i) the United Kingdom, (ii) any other
         jurisdiction from which, or through which, such payment is made or to
         the taxation laws of which the relevant Borrower is at the time of such
         payment subject, (iii) any political sub-division of the United Kingdom
         or any such other jurisdiction or (iv) any federation or association of
         states of which the United Kingdom or any such other jurisdiction is,
         at the time of such payment, a member.

         TAX RECEIPTS

11.2     All Relevant Taxes required by law to be deducted or withheld by any
         Borrower from any amount paid or payable under this Agreement shall be
         paid by such Borrower when due (unless the obligation to pay is being
         disputed in good faith) and such Borrower shall, within 30 days of the
         payment being made, deliver to the Bank evidence satisfactory to the
         Bank (including all relevant tax receipts) that the payment has been
         duly remitted to the appropriate authority.

         TAX CREDITS

11.3     If any Borrower pays any additional amount (a "TAX PAYMENT") under
         Clause 11.1 and the Bank effectively obtains a refund of tax, or a
         relief or credit against tax by reason of that Tax Payment (a "TAX
         CREDIT"), and the Bank is able to identify the Tax Credit as being
         attributable to the Tax Payment, then the Bank shall reimburse to the
         relevant Borrower such amount as the Bank reasonably determines to be
         the proportion of the Tax Credit as will leave the Bank (after that
         reimbursement) in no better or worse position that it would have been
         if the Tax Payment had not been required. Nothing in this Clause
         interferes with the right of the Bank to arrange its tax affairs in
         whatever manner it thinks fit and, without prejudice to the foregoing,
         the Bank is under no obligation to claim a Tax Credit, or to claim a
         Tax Credit in priority to any other claim, relief, credit or deduction
         available to it. The Bank is not obliged to disclose any information
         regarding its tax affairs or computations to any Borrower.

         QUALIFYING BANK

11.4     If, otherwise than as a result of the introduction of, change in, or
         change in the interpretation, administration or application of, any law
         or regulation or any practice or concession of the Inland Revenue after
         the Signing Date, the Bank ceases to be a Qualifying Bank no Borrower
         shall be liable to pay to the Bank under Clause 11.1 (Gross-up) any
         amount in respect of taxes levied or imposed by the UK or any taxing
         authority thereof or therein in excess of the amount it would have been
         obliged to pay if the Bank had been or had not ceased to be a
         Qualifying Bank.

12.      MARKET DISRUPTION

         MARKET DISRUPTION

12.1     If, in relation to any proposed Utilisation:

         12.1.1   the Bank is unable to obtain from leading banks a rate for the
                  purposes of determining the applicable LIBOR or the Bank
                  otherwise determines that adequate and fair means do not exist
                  for ascertaining the applicable LIBOR; or

         12.1.2   in the opinion of the Bank:

                  (a)  matching deposits may not be available to it in the
                       London Interbank Market in the ordinary course of
                       business to fund an Advance; or

                  (b)  the cost to it of matching deposits in the London
                       Interbank Market would be in excess of the relevant
                       LIBOR,

                  the Bank shall notify the Company by 10.30 a.m. or as soon as
                  is practicable thereafter on the Rate Fixing Day of the fact
                  and that this Clause is in operation.

12.2     After any notification under Clause 12.1 above:

         12.2.1   subject to sub-Clause 12.2.3 below the relevant Advance shall
                  be made in Sterling in an amount equal to its Original
                  Sterling Amount (unless Sterling was the original currency of
                  the relevant Advance);

         12.2.2   subject to sub-Clause 12.2.3 below, no further notices of
                  Utilisation by telephone or Requests for Advances to be
                  denominated in the original currency of the affected Advance
                  may be delivered until the Bank notifies the Company that the
                  event specified in the notification no longer prevails;

         12.2.3   the relevant Borrower may, by notice to the Bank by 11.00 a.m.
                  (or, if later, within 30 minutes of receipt by the Company of
                  a notification under sub-Clause 12.1.2) on the Rate Fixing
                  Day: (i) elect for the


<PAGE>   21

                  notice of Utilisation by telephone or the Request to be
                  cancelled without penalty; (ii) if the Advance was to be made
                  in an Optional Currency, elect for the Advance to be made in
                  an Optional Currency other than a currency affected by the
                  event specified in the notification or (iii) elect for the
                  Advance to be made in accordance with the Request
                  notwithstanding the event specified in the notification. If
                  any Borrower requires an affected Advance to be made in the
                  original currency selected for such Advance notwithstanding
                  the event specified in the notification then within five
                  Business Days of receipt of the notification, the Company and
                  the Bank shall enter into negotiations for a period of not
                  more than 25 days with a view to agreeing a substitute basis
                  for determining the rate of interest and/or funding applicable
                  to the affected Advance and any future Advances in the
                  currency of the affected Advance provided that if no
                  substitute basis is agreed within that period:

                  (a)  the Bank shall certify to the Company (such certificate
                       to be conclusive) the alternative interest rate
                       calculated in accordance with sub-Clause 12.2.4 below;

                  (b)  the certificate may make provision for different funding
                       periods and shall be retroactive to the beginning of the
                       then current Term; and

                  (c)  the certificate shall be binding on each relevant
                       Borrower unless the Company gives notice to the Bank
                       within five Business Days of the receipt of the
                       certificate that the certificate is not acceptable and
                       that each relevant Borrower shall prepay in full the
                       relevant Advances on a Business Day specified in the
                       notice, which shall be not less than five nor more than
                       thirty days after the date of the Bank's certificate to
                       the Company; and

         12.2.4   for the purposes of sub-Clause 12.2.3(a) above the rate of
                  interest on each Advance shall be the rate certified by the
                  Bank as the rate per annum determined by the Bank to be the
                  aggregate of:

                  (a)  the Margin;

                  (b)  the rate notified by the Bank, on or before the last day
                       of its Term, as being the cost to the Bank of funding the
                       Advance from such other sources as it may reasonably
                       select; and

                  (c)  the applicable Mandatory Cost if any.

12.3     During the period when any substitute basis is in force in relation to
         a particular currency, the Bank shall periodically determine whether
         the circumstances referred to in Clause 12.1 above still apply and, if
         they do not, shall forthwith give notice in writing to the Company of
         the date on which the substitute basis will cease to apply.

13.      INCREASED COSTS

         INCREASED COSTS - SERVICE OF DEMAND

13.1     If the result of any introduction of or change in any law or regulation
         after the Signing Date, or of any change in the application or
         interpretation of any such changed law or regulation or compliance by
         the Bank with any such changed law or regulation after the Signing Date
         (including, without limitation, any law or regulation relating to
         taxation, any reserve, special deposit, cash ratio, liquidity or
         capital adequacy requirement or any form of banking or monetary control
         but excluding (i) changes arising from the implementation by any
         authority having jurisdiction over the Bank or its holding company of
         the matters set out in the statement prepared by the Basle Committee on
         Banking Regulations and Supervisory Practices dated July 1988 and
         entitled "International Convergence of Capital Measurement and Capital
         Standards" (as amended in November 1991) and (ii) changes arising from
         the implementation in whole or in part by any authority having
         jurisdiction over the Bank or its holding company of the proposals
         contained in the matters set out in the EC Directive 93/6/EEC of 15
         March 1993 on the capital adequacy of investment firms and credit
         institutions) is that the Bank incurs an increased cost, then the Bank
         will promptly notify the Company of the relevant event and the Company
         shall on demand pay to the Bank such amount as the Bank certifies in
         the demand will compensate it for the applicable increased cost.

13.2     In this Clause 13 "increased cost" means:

         13.2.1   an additional cost incurred by the Bank as a result of it
                  having entered into, or performing, maintaining or funding its
                  obligations under, this Agreement; or

         13.2.2   that portion of an additional cost incurred by the Bank in
                  making, funding or maintaining all or any advances comprised
                  in a class of advances formed by or including the Advances
                  made or to be made by it under this Agreement as is
                  attributable to it making, funding, or maintaining such
                  advances; or

         13.2.3   a reduction in any amount payable to the Bank or the effective
                  return to the Bank under this Agreement or on its capital; or

         13.2.4   any payment made or interest or other return on or calculated
                  by reference to any amount received or receivable by the Bank
                  under this Agreement which is forgone.

13.3     When calculating an increased cost, the Bank may allocate or spread
         costs, liabilities and losses to or across its liabilities or assets,
         or any class of liabilities or assets, and on such basis, as it
         reasonably considers appropriate.

         INCREASED COSTS - EXCEPTIONS

13.4     An increased cost does not include any increased cost:


<PAGE>   23

         13.4.1   compensated for by the payment of the Mandatory Cost;

         13.4.2   compensated for by the operation of Clause 11 (Taxes);

         13.4.3   attributable to any change in the rate of tax on the overall
                  net income of the Bank (or the overall net income of a
                  division or branch of the Bank) imposed in the jurisdiction in
                  which its principal office or the relevant lending office for
                  the time being is situate;

         13.4.4   payable to an assignee or transferee of the Bank at the time
                  of an assignment, transfer or novation under Clause 25
                  (Changes to the Parties), but only to the extent that the
                  increased cost would not have been payable to the assigning,
                  transferring or novating Bank; or

         13.4.5   which is attributable to the introduction of the euro other
                  than an increased cost which is being incurred generally by
                  banks transacting euro business in the London interbank
                  market.

14.      ILLEGALITY

14.1     If it is or becomes unlawful for the Bank to give effect to any of its
         obligations as contemplated by this Agreement or to fund or maintain
         any Advance, then the Bank shall notify the Company accordingly and on
         the Maturity Date of each relevant Advance (or such earlier date as the
         relevant law or directive may require) the relevant Borrower shall
         repay or prepay, as the case may be, any Advances made to it by the
         Bank together with all other amounts payable by it to the Bank under
         this Agreement.

14.2     The Bank's Commitment shall be cancelled on the date of a notification
         under Clause 14.1 above.

15.      TAXES AND INCREASED COSTS - ADDITIONAL RIGHTS

         PREPAYMENT AND CANCELLATIONS

15.1     If any Borrower is required to pay any additional amounts to the Bank
         under Clause 11 (Taxes) or compensation under Clause 13 (Increased
         Costs), the Company may, whilst the circumstances giving rise to the
         requirement continue, serve a notice of prepayment and cancellation in
         relation to all or all affected Advances on the Bank.

15.2     On the tenth Business Day after the date of service of the notice the
         relevant Borrower shall prepay the relevant Advance or Advances made to
         it by the Bank together with all other amounts in relation to such
         Advance(s) payable by it to the Bank under this Agreement.

15.3     To the extent of the Advances referred to in the notice of prepayment
         and cancellation, but not further or otherwise, the Bank's Commitment
         shall be cancelled on the date of service of the notice.


<PAGE>   24

         MITIGATION

15.4     If, in respect of the Bank, circumstances arise which would or would,
         with the giving of notice, result in:

         15.4.1   any additional amounts becoming payable under Clause 11
                  (Taxes); or

         15.4.2   any increased cost becoming payable under Clause 13 (Increased
                  Costs); or

         15.4.3   any prepayment, payment or cancellation under Clause 14
                  (Illegality),

         then the Bank shall endeavour to take such steps as are reasonably open
         to it to mitigate or remove those circumstances (including seeking
         recovery for the account of the relevant Borrower where reasonably
         practicable and/or transferring its rights and obligations under this
         Agreement to another bank or financial institution acceptable to the
         Company).

15.5     Clause 15.4 above does not:

         15.5.1   prejudice the obligations of any Borrower under this Agreement
                  (including, without limitation, under the Clauses referred to
                  in Clause 15.4 above); or

         15.5.2   require the Bank to take any action which, in its opinion,
                  might be in any way prejudicial to it or conflict with its
                  banking policies.

         (inclusive) occurs in relation to a Material Subsidiary which is not a
         Borrower it will only be an Event of Default if the event is, in the

         a breach capable of being remedied) fails to remedy the breach within
         fourteen Business Days after the date on which the Company and the
         relevant Borrower receive notice of the breach from the Bank.

31.      DESIGNATION OF ACCEDING AND SECEDING BORROWERS

31.1     The Company may request that any of its Subsidiaries incorporated in
         England and Wales and, with the prior written consent of the Bank (such
         consent not to be unreasonably withheld or delayed) any other
         Subsidiary of the Company becomes an Acceding Borrower by delivering or
         procuring the delivery to the Bank a Borrower's Accession Notice duly
         executed by the Company and the relevant Subsidiary provided that if
         such Subsidiary is not resident in the United Kingdom for tax purposes
         the Company and the Bank agree to make such amendments to this
         Agreement as may be reasonably required at the time in


<PAGE>   40

         order to allow such Subsidiary to pay interest to the Bank without
         deduction or withholding of any Relevant Tax and to provide such
         Subsidiary with equivalent rights, mutatis mutandis, to those contained
         in Clause 11.4 (Qualifying Bank).

31.2     Upon delivery of a Borrower's Accession Notice, the relevant Subsidiary
         shall become an Acceding Borrower and shall, subject to the terms and
         conditions of this Agreement acquire all the rights and assume all the
         obligations of a Borrower hereunder provided that the Bank has
         confirmed to the Company that it has received, in form and substance
         satisfactory to it, all the documents set out in Part II of Schedule 1.

31.3     The Company undertakes that it shall procure that each Acceding
         Borrower shall provide the Bank with each of the documents listed in
         Part II of Schedule 1.

31.4     If at any time any Borrower (other than the Company) has no actual or
         contingent obligation under this Agreement, the Company may deliver a
         Borrower's Cessation Notice to the Bank in which event such Borrower
         shall forthwith cease to be a Borrower upon receipt by the Bank of such
         notice.

32.      CHANGE OF CURRENCY

32.1     If more than one currency or currency unit are at the same time
         recognised by the central bank of any country as the lawful currency of
         that country, then:

         32.1.1   any reference in this Agreement to, and any obligations
                  arising under this Agreement in, the currency of that country
                  shall be translated into, or paid in, the currency unit of
                  that country designated by the Bank acting reasonably and in
                  consultation with the Company; and

         32.1.2   any translation from one currency unit to another shall be at
                  the official rate of exchange recognised by the relevant
                  central bank for the conversion of that currency or currency
                  unit into the other, rounded up or down by the Bank acting
                  reasonably.

32.2     If a change in any currency of a country occurs, the Bank and the
         Company will negotiate in good faith in order to agree any amendments
         to this Agreement to reflect market practice at that time with regard
         to the occurrence of EMU within the European Union or any part(s) of it
         and the new currency and to put the Bank and the Borrowers in the same
         position, so far as is possible, that they would have been in if no
         change in currency had occurred.

32.3     The Bank and the Company agree that the occurrence or non-occurrence of
         EMU within the European Union or part(s) of it and/or any event or
         events associated with EMU and/or the introduction of any new currency
         in all or any part of the European Union will not result in the
         discharge cancellation, rescission or termination in whole or in pat of
         this Agreement or give any party hereto the right to cancel, rescind,
         terminate or vary (other than as aforesaid) this Agreement in whole or
         in part or give rise to an Event of Default.

33.      COUNTERPARTS

         which shall be an original and all of such counterparts taken together
         shall be delivered to constitute one and the same instrument.

34.      APPLICABLE LAW AND JURISDICTION

34.1     The law of England and Wales is the law applicable to this Agreement.

34.2     Each of the Borrowers irrevocably agrees for the benefit of the Bank
         that the courts of England shall have jurisdiction to hear and
         determine any suit, action or proceeding, and to settle any disputes,
         which may arise out of or in connection with this Agreement and, for
         such purposes, irrevocably submits to the jurisdiction of such courts.

34.3     Each of the Borrowers which is not incorporated in England and Wales
         agrees that the process by which any suit, action or proceeding is
         begun in England and Wales may be served on it by being delivered to
         the Company at its registered office for the time being and hereby
         appoints the Company (and the Company accepts such appointment) for
         such purposes. If the appointment of the person mentioned in this
         Clause 34.3 ceases to be effective in respect of any or all of the
         Borrowers such Borrower or Borrowers shall immediately appoint a
         further person in England and Wales to accept service of process on its
         behalf in England and Wales and, failing such appointment within
         fifteen days, the Bank acting reasonably shall be entitled to appoint
         such a person by notice to such Borrower or Borrowers. Nothing
         contained herein shall affect the right to serve process in any other
         manner permitted by law.

34.4     Each of the Borrowers irrevocably waives any objection which it might
         now or hereafter have to the courts referred to in Clause 34.2 being
         nominated as the forum to hear and determine any suit, action or
         proceeding, and to settle any disputes, which may arise out of or in
         connection with this Agreement and agrees not to claim that any such
         court is not a convenient or appropriate forum.

34.5     The submission to the jurisdiction of the courts referred to in Clause
         34.2 shall not (and shall not be construed so as to) limit the right of
         the Bank to take proceedings against any of the Borrowers in any other
         court of competent jurisdiction nor shall the taking of proceedings in
         any one or more jurisdictions preclude the taking of proceedings in any
         other jurisdiction (whether concurrently or not) if and to the extent
         permitted by applicable law.

  This Agreement has been entered into on the date stated at the beginning of
                                this Agreement.

                     (b)        no Default is outstanding or might result from
                                the Utilisation; and

           4.2.2     the Utilisation would not cause Clause 2.2 (Overall
                     facility limit) to be contravened.

           4.2.3     in the case of the first Utilisation either:

                     (a)        the total aggregate amounts outstanding under
                                the Revolving Multi-Currency Credit Facility
                                Agreement dated 14th May 1993 (as amended) made
                                between the Company and the Bank, the "Existing
                                Outstandings", shall have been repaid or prepaid
                                in full and the aggregate commitments under such
                                facility agreement cancelled on the day of such
                                repayment or prepayment; or

                     (b)        the amount of the first Utilisation together
                                with other sums available to the Borrower shall
                                be used to repay or prepay the Existing
                                Outstandings and the aggregate commitments under
                                such facility agreement cancelled on the day of
                                such repayment or prepayment.

           the Bank not later than the close of business in London on the day on
           which such telephone notice is, or is deemed to have been, given.

           COMPLETION OF REQUESTS

5.3        When giving a notice of Utilisation by telephone and when completing
           the Request, the relevant Borrower must ensure that:

           5.3.1     the Utilisation Date is a Business Day;

           5.3.2     only one currency is specified and that the Requested
                     Amount is:

                     (a)        if the currency is Sterling, a minimum of
                                Pound Sterling 1,000,000 and an integral
                                multiple of Pound Sterling 100,000; or

                     (b)        if the currency is Dollars, a minimum of US
                                $1,000,000 and an integral multiple of US
                                $100,000; or

                     (c)        if the currency is an Optional Currency other
                                than Dollars, a minimum and integral multiple of
                                the amounts agreed between the relevant Borrower
                                and the Bank before the telephone notice of
                                Utilisation or delivery of that Request; or

                     (d)        such other amounts as the Bank and the relevant
                                Borrower may agree;

           5.3.3     only one Term is specified which:

                     (a)        does not overrun the Final Maturity Date; and

                     (b)        is a period of an approved duration or of an
                                optional duration; and

           5.3.4     the payment instructions comply with Clause 9 (Payments).

           In this Clause:

           "APPROVED DURATION" means a period of 1, 2, 3 or 6 months; and

           "OPTIONAL DURATION" means any other period not exceeding 12 months.

           SELECTION OF TERM OF OPTIONAL DURATION

5.4        If the relevant Borrower selects a Term of an optional duration, it
           may also select at the time of the telephone notice of Utilisation
           and in the relevant Request a Term of any approved duration to apply
           if the selection of a Term of an optional duration becomes
           ineffective in accordance with Clause 5.5.2.

5.5        If:

           5.5.1     the relevant Borrower requests a Term of an optional
                     duration; and
<PAGE>   12

           5.5.2     the Bank notifies such Borrower not later than 10.30 a.m.
                     on the date of receipt by it of the relevant Request or
                     telephone notice of Utilisation pursuant to Clause 5.1 or
                     Clause 5.2 respectively that it does not agree to that
                     request,

           the Term for the proposed Utilisation shall be the alternative period
           specified in the telephone notice of Utilisation or the relevant
           Request or, in the absence of any alternative selection, 3 months.

           PAYMENT OF PROCEEDS

5.6        Subject to the terms of this Agreement, the Bank shall make the
           Advance available to the relevant Borrower on the relevant
           Utilisation Date.

6.         CANCELLATION

           AUTOMATIC CANCELLATION OF THE COMMITMENT

6.1        The Commitment shall be automatically cancelled at close of business
           on the Final Maturity Date.

           VOLUNTARY CANCELLATION

6.2        The Company may, without penalty and by giving not less than 15 days'
           prior notice to the Bank, cancel the Commitment in whole or in part.

6.3        A notice of cancellation will be irrevocable and shall specify:

           6.3.1     the date on which the cancellation is to become effective;
                     and

           6.3.2     the amount of the Commitment to be cancelled.

6.4        Any cancellation may only take effect in respect of the unutilised
           portion of the Commitment as at the date the notice is to be
           effective.

           NO REINSTATEMENT

6.5        No amount of the Commitment cancelled under this Agreement may
           subsequently be instated.

7.         INTEREST

           INTEREST RATE

7.1        The rate of interest on each Advance for its Term is the rate per
           annum determined by the Bank to be the aggregate of the applicable:

           7.1.1     Margin,

           7.1.2     LIBOR; and
<PAGE>   13

           7.1.3     Mandatory Costs.

           DUE DATES

7.2        Except as otherwise provided in this Agreement, accrued interest on
           each Advance is payable on its Maturity Date and also, in the case of
           an Advance with a term longer than six months, on the date falling
           six months after its Utilisation Date.

           DEFAULT INTEREST

7.3        If any Borrower fails to pay any amount payable by it under this
           Agreement, it shall, on demand by the Bank from time to time, pay
           interest on the overdue amount from the due date up to the date of
           actual payment, after as well as before judgment, at a rate (the
           "DEFAULT RATE") determined by the Bank to be one (1) per cent. per
           annum above the higher of:

           7.3.1     the rate on the overdue amount under Clause 7.1 (Interest
                     rate) immediately before the due date (but only if the
                     overdue amount is an Advance (or part thereof) and only for
                     the period up to and including the Maturity Date of that
                     Advance); and

           7.3.2     the rate which would have been payable if the overdue
                     amount had, during the period of non-payment, constituted
                     an Advance in the currency of the overdue amount for such
                     successive Terms of such duration (not exceeding three
                     months) as the Bank may reasonably determine (each a
                     "DESIGNATED TERM").

7.4        The default rate will be determined on the first day of, or two
           Business Days before the first day of, the relevant Designated Term,
           as appropriate.

7.5        If the Bank determines that deposits in the currency of the overdue
           amount are not at the relevant time being made available by leading
           banks in the London Interbank Market, the default rate will be
           determined by reference to the cost of funds to the Bank from
           whatever sources it may reasonably select.

7.6        Default interest shall be compounded at the end of each Designated
           Term until it is paid.

           NOTIFICATION OF RATES OF INTEREST

7.7        The Bank shall promptly notify the relevant Borrower of the
           determination of any applicable rate of interest under this
           Agreement.

8.         REPAYMENT AND PREPAYMENT

           REPAYMENT OF ADVANCES

8.1        Each Borrower shall repay each Advance made to it in full on its
           Maturity Date to the Bank. If an Advance (the "NEW ADVANCE") is to be
           made to a Borrower on the day on which another Advance (the "MATURING
           ADVANCE")


<PAGE>   14

           in the same currency is due to be repaid by such Borrower then,
           subject to the terms of this Agreement and so long as the conditions
           referred to in Clause 4.2 shall have been satisfied in relation to
           the New Advance:

           8.1.1     the Maturing Advance shall be deemed to have been repaid on
                     its Maturity Date either in whole (if the New Advance is
                     equal to or greater than the Maturing Advance) or in part
                     (if the New Advance is less than the Maturing Advance); and

           8.1.2     to the extent that a Maturing Advance is so deemed to have
                     been repaid, the principal amount of the New Advance to be
                     made on such a date shall be deemed to have been credited
                     to the account of such Borrower by the Bank in accordance
                     with the terms of this Agreement and, as the case may be:

                     (a)        the Bank shall only be obliged to make available
                                to such Borrower pursuant to Clause 5.6 a
                                principal amount equal to the amount (if any) by
                                which the New Advance exceeds the Maturing
                                Advance; or

                     (b)        such Borrower shall only be obliged to pay to
                                the Bank pursuant to this Clause 8.1 a principal
                                amount equal to the amount by which the Maturing
                                Advance exceeds the New Advance.

8.2        On the Final Maturity Date, all outstanding Advances and other sums
           (if any) then owing under this Agreement shall in any event be repaid
           or paid in full.

           PREPAYMENT OF ADVANCES

8.3        Any Borrower may, without penalty and on giving not less than 15
           days' prior notice to the Bank, prepay all or any part of an Advance,
           but if in part, in a minimum amount of Pound Sterling 1,000,000 and
           an integral multiple of Pound Sterling 100,000 (or the comparable
           amount in any Optional Currency).

8.4        Any notice by a Borrower of prepayment under this Agreement is
           irrevocable.

8.5        Should any person or group of persons, acting either individually or
           in concert (as defined in the City Code on Take Overs and Mergers
           effective as at the date of this Agreement) otherwise than with the
           consent of the Bank acquire control of the Company (and for the
           purpose of this Clause a single person or group of persons shall have
           acquired control if it or they own or hold more than 50% (fifty per
           cent.) of the issued share capital of the Company having the right to
           attend and vote at general meetings of the Company or more than 50%
           (fifty per cent.) of such rights), then:

           8.5.1     the Company shall immediately upon becoming aware thereof
                     notify the Bank specifying the date of such acquisition and
                     the name of such person or persons acquiring control; and


<PAGE>   15

           8.5.2     thereafter no Borrower shall be permitted to request an
                     Advance unless the terms of the acquisition of control of
                     the Company were approved by the Board of Directors of the
                     Company and the Maturity Date for any Advance requested
                     falls on a date not more than three months after the
                     expiration of the 30 day period referred to in Clause 8.6.

8.6        If the terms of the acquisition of control of the Company were
           approved by the Board of Directors of the Company, the Bank shall
           consult with the Company during the period of 30 days after receipt
           of the notification from the Company referred to in sub-Clause 8.5.1
           and shall be entitled to give notice of continuance of the Facility
           provided hereunder to the Company. Upon receipt of such notice of
           continuance, the right of the Borrowers to request an Advance without
           the limitation referred to in sub-Clause 8.5.2 shall be reinstated.

8.7        If the terms of the acquisition of control of the Company were
           approved by the Board of Directors of the Company but, at the end of
           the period of 30 days referred to in Clause 8.6 above, the Company
           has not received a notice of continuance then:

           8.7.1     the Facility shall be cancelled;

           8.7.2     any outstanding Advances with Maturity Dates falling later
                     than three months after the end of such period shall be
                     prepaid on the date falling three months after the end of
                     such period, together with accrued interest thereon up to
                     the date of payment and all other amounts payable to the
                     Bank hereunder; and

           8.7.3     any outstanding Advances with Maturity Dates falling not
                     later than three months after the end of such period shall
                     be repaid on their respective Maturity Dates.

8.8        If the terms of the acquisition of control of the Company were not
           approved by the Board of Directors of the Company, then unless the
           Bank shall have confirmed within 2 days of receipt of the notice
           referred to in sub-Clause 8.5.1 that the Facility shall be continued,
           the Facility shall be cancelled and any outstanding Advances shall be
           repayable on demand by the Bank together with accrued interest
           thereon up to the date of payment and all other amounts payable to
           the Bank hereunder.

8.9        Any prepayment under this Agreement shall be made together with
           accrued interest on the amount prepaid together with any amount
           payable to the Bank pursuant to Clause 22.3.

8.10       No Advance may be prepaid otherwise than in accordance with the
           express terms of this Agreement.

           Borrower under this Agreement in the following order:

           9.11.1    firstly, in or towards payment of any unpaid costs and
                     expenses of the Bank under this Agreement;

           9.11.2    secondly, in or towards payment of any accrued fees due but
                     unpaid under Clause 19.2 (Commitment Fee);

           9.11.3    thirdly, in or towards payment of any accrued interest due
                     but unpaid under this Agreement;

           9.11.4    fourthly, in or towards payment of any principal due but
                     unpaid under this Agreement, and

           9.11.5    fifthly, in or towards payment of any other sum due but
                     unpaid under this Agreement.

9.12       The Bank may vary the order set out in Clauses 9.11.1 to 9.11.5
           above.

9.13       Clauses 9.11 and 9.12 above shall override any  appropriation made by
           any Borrower.

10.        OPTIONAL CURRENCIES

           SELECTION

10.1       No Borrower may request an Advance denominated in an Optional
           Currency unless the Bank has confirmed to such Borrower that the
           Optional Currency is readily available and freely transferable in the
           London foreign exchange market.



<PAGE>   18

           CHANGE OF CURRENCY

10.2       If, on the Rate Fixing Day of an Advance to be denominated in an
           Optional Currency, the Bank determines that:

           10.2.1    it is impracticable for reasons beyond its control for the
                     Bank to fund the Advance for its Term in that Optional
                     Currency in the ordinary course of business in the London
                     Interbank Market; or

           10.2.2    the use of the proposed Optional Currency might contravene
                     any law or regulation,

           then:

           10.2.3    the Bank shall promptly and in any event before 10.30 a.m.
                     on that Rate Fixing Day notify the relevant Borrower;

           10.2.4    if the Bank receives notice from the relevant Borrower by
                     11.30 a.m. on that Rate Fixing Day to that effect, the
                     Advance will not be made; and

           10.2.5    if the Bank does not receive any notice under sub-Clause
                     10.2.4 above, the Advance will be denominated instead in
                     Sterling in an amount equal to its Original Sterling
                     Amount.

           NOTIFICATION OF RATES AND AMOUNTS

10.3       The Bank shall, on request, promptly notify the relevant Borrower of
           any applicable Bank's Spot Rate of Exchange or Original Sterling
           Amount promptly after it has been ascertained.

10.4       If an Advance which has been drawn in an Optional Currency is
           reborrowed in the same Optional Currency immediately following its
           repayment, then the Original Sterling Amount of such new Advance
           denominated in such Optional Currency shall be recalculated for the
           new Term in accordance with the terms and conditions of this
           Agreement and if on the relevant Utilisation Date the aggregate
           Original Sterling Amount of all Advances outstanding on such date
           exceeds the Commitment, then any excess shall be repaid to the Bank
           by the relevant Borrower upon the Bank's first written demand.

11.        TAXES

           GROSS-UP

11.1       All payments by each of the Borrowers under this Agreement shall be
           made without any deductions and free and clear of and without
           deduction for or on account of any Relevant Taxes except to the
           extent that any Borrower is required by law to make payment subject
           to any such taxes. If any Relevant Tax or amounts in respect of any
           Relevant Tax must be deducted from any amounts payable or paid by any
           Borrower hereunder, such Borrower shall pay




<PAGE>   19

           such additional amounts as may be necessary to ensure that the Bank
           receives a net amount equal to the full amount which it would have
           received had payment not been made subject to tax.

           "RELEVANT TAX" in relation to any payment which falls to be made
           hereunder means any present or future taxes of any nature now or
           hereafter imposed by the laws of (i) the United Kingdom, (ii) any
           other jurisdiction from which, or through which, such payment is made
           or to the taxation laws of which the relevant Borrower is at the time
           of such payment subject, (iii) any political sub-division of the
           United Kingdom or any such other jurisdiction or (iv) any federation
           or association of states of which the United Kingdom or any such
           other jurisdiction is, at the time of such payment, a member.

           TAX RECEIPTS

11.2       All Relevant Taxes required by law to be deducted or withheld by any
           Borrower from any amount paid or payable under this Agreement shall
           be paid by such Borrower when due (unless the obligation to pay is
           being disputed in good faith) and such Borrower shall, within 30 days
           of the payment being made, deliver to the Bank evidence satisfactory
           to the Bank (including all relevant tax receipts) that the payment
           has been duly remitted to the appropriate authority.

           TAX CREDITS

11.3       If any Borrower pays any additional amount (a "TAX PAYMENT") under
           Clause 11.1 and the Bank effectively obtains a refund of tax, or a
           relief or credit against tax by reason of that Tax Payment (a "TAX
           CREDIT"), and the Bank is able to identify the Tax Credit as being
           attributable to the Tax Payment, then the Bank shall reimburse to the
           relevant Borrower such amount as the Bank reasonably determines to be
           the proportion of the Tax Credit as will leave the Bank (after that
           reimbursement) in no better or worse position that it would have been
           if the Tax Payment had not been required. Nothing in this Clause
           interferes with the right of the Bank to arrange its tax affairs in
           whatever manner it thinks fit and, without prejudice to the
           foregoing, the Bank is under no obligation to claim a Tax Credit, or
           to claim a Tax Credit in priority to any other claim, relief, credit
           or deduction available to it. The Bank is not obliged to disclose any
           information regarding its tax affairs or computations to any
           Borrower.

           QUALIFYING BANK

11.4       If, otherwise than as a result of the introduction of, change in, or
           change in the interpretation, administration or application of, any
           law or regulation or any practice or concession of the Inland Revenue
           after the Signing Date, the Bank ceases to be a Qualifying Bank no
           Borrower shall be liable to pay to the Bank under Clause 11.1
           (Gross-up) any amount in respect of taxes levied or imposed by the UK
           or any taxing authority thereof or therein in excess of the amount it
           would have been obliged to pay if the Bank had been or had not ceased
           to be a Qualifying Bank.

12.        MARKET DISRUPTION

           MARKET DISRUPTION

12.1       If, in relation to any proposed Utilisation:

           12.1.1    the Bank is unable to obtain from leading banks a rate for
                     the purposes of determining the applicable LIBOR or the
                     Bank otherwise determines that adequate and fair means do
                     not exist for ascertaining the applicable LIBOR; or

           12.1.2    in the opinion of the Bank:

                     (a)        matching deposits may not be available to it in
                                the London Interbank Market in the ordinary
                                course of business to fund an Advance; or

                     (b)        the cost to it of matching deposits in the
                                London Interbank Market would be in excess of
                                the relevant LIBOR,

                     the Bank shall notify the Company by 10.30 a.m. or as soon
                     as is practicable thereafter on the Rate Fixing Day of the
                     fact and that this Clause is in operation.

12.2       After any notification under Clause 12.1 above:

           12.2.1    subject to sub-Clause 12.2.3 below the relevant Advance
                     shall be made in Sterling in an amount equal to its
                     Original Sterling Amount (unless Sterling was the original
                     currency of the relevant Advance);

           12.2.2    subject to sub-Clause 12.2.3 below, no further notices of
                     Utilisation by telephone or Requests for Advances to be
                     denominated in the original currency of the affected
                     Advance may be delivered until the Bank notifies the
                     Company that the event specified in the notification no
                     longer prevails;

           12.2.3     the relevant Borrower may, by notice to the Bank by 11.00
                     a.m. (or, if later, within 30 minutes of receipt by the
                     Company of a notification under sub-Clause 12.1.2) on the
                     Rate Fixing Day: (i) elect for the notice of Utilisation by
                     telephone or the Request to be cancelled without penalty;
                     (ii) if the Advance was to be made in an Optional Currency,
                     elect for the Advance to be made in an Optional Currency
                     other than a currency affected by the event specified in
                     the notification or (iii) elect for the Advance to be made
                     in accordance with the Request notwithstanding the event
                     specified in the notification. If any Borrower requires an
                     affected Advance to be made in the original currency
                     selected for such Advance notwithstanding the event
                     specified in the notification then within five Business
                     Days of receipt of the notification, the Company and the
                     Bank shall enter into negotiations for a period of not more
                     than 25 days with a view to agreeing a substitute basis for
                     determining the rate




<PAGE>   21

                     of interest and/or funding applicable to the affected
                     Advance and any future Advances in the currency of the
                     affected Advance provided that if no substitute basis is
                     agreed within that period:

                     (a)        the Bank shall certify to the Company (such
                                certificate to be conclusive) the alternative
                                interest rate calculated in accordance with
                                sub-Clause 12.2.4 below;

                     (b)        the certificate may make provision for different
                                funding periods and shall be retroactive to the
                                beginning of the then current Term; and

                     (c)        the certificate shall be binding on each
                                relevant Borrower unless the Company gives
                                notice to the Bank within five Business Days of
                                the receipt of the certificate that the
                                certificate is not acceptable and that each
                                relevant Borrower shall prepay in full the
                                relevant Advances on a Business Day specified in
                                the notice, which shall be not less than five
                                nor more than thirty days after the date of the
                                Bank's certificate to the Company; and

           12.2.4    for the purposes of sub-Clause 12.2.3(a) above the rate of
                     interest on each Advance shall be the rate certified by the
                     Bank as the rate per annum determined by the Bank to be the
                     aggregate of:

                     (a)        the Margin;

                     (b)        the rate notified by the Bank, on or before the
                                last day of its Term, as being the cost to the
                                Bank of funding the Advance from such other
                                sources as it may reasonably select; and

                     (c)        the applicable Mandatory Cost if any.

12.3       During the period when any substitute basis is in force in relation
           to a particular currency, the Bank shall periodically determine
           whether the circumstances referred to in Clause 12.1 above still
           apply and, if they do not, shall forthwith give notice in writing to
           the Company of the date on which the substitute basis will cease to
           apply.

13.        INCREASED COSTS

           INCREASED COSTS - SERVICE OF DEMAND

13.1       If the result of any introduction of or change in any law or
           regulation after the Signing Date, or of any change in the
           application or interpretation of any such changed law or regulation
           or compliance by the Bank with any such changed law or regulation
           after the Signing Date (including, without limitation, any law or
           regulation relating to taxation, any reserve, special deposit, cash
           ratio, liquidity or capital adequacy requirement or any form of
           banking or monetary control but excluding (i) changes arising from
           the implementation by any


<PAGE>   22

           authority having jurisdiction over the Bank or its holding company of
           the matters set out in the statement prepared by the Basle Committee
           on Banking Regulations and Supervisory Practices dated July 1988 and
           entitled "International Convergence of Capital Measurement and
           Capital Standards" (as amended in November 1991) and (ii) changes
           arising from the implementation in whole or in part by any authority
           having jurisdiction over the Bank or its holding company of the
           proposals contained in the matters set out in the EC Directive
           93/6/EEC of 15 March 1993 on the capital adequacy of investment firms
           and credit institutions) is that the Bank incurs an increased cost,
           then the Bank will promptly notify the Company of the relevant event
           and the Company shall on demand pay to the Bank such amount as the
           Bank certifies in the demand will compensate it for the applicable
           increased cost.

13.2       In this Clause 13 "INCREASED COST" means:

           13.2.1    an additional cost incurred by the Bank as a result of it
                     having entered into, or performing, maintaining or funding
                     its obligations under, this Agreement; or

           13.2.2    that portion of an additional cost incurred by the Bank in
                     making, funding or maintaining all or any advances
                     comprised in a class of advances formed by or including the
                     Advances made or to be made by it under this Agreement as
                     is attributable to it making, funding, or maintaining such
                     advances; or

           13.2.3    a reduction in any amount payable to the Bank or the
                     effective return to the Bank under this Agreement or on its
                     capital; or

           13.2.4    any payment made or interest or other return on or
                     calculated by reference to any amount received or
                     receivable by the Bank under this Agreement which is
                     forgone.

13.3       When calculating an increased cost, the Bank may allocate or spread
           costs, liabilities and losses to or across its liabilities or assets,
           or any class of liabilities or assets, and on such basis, as it
           reasonably considers appropriate.

           INCREASED COSTS - EXCEPTIONS

13.4       An increased cost does not include any increased cost:

           13.4.1    compensated for by the payment of the Mandatory Cost;

           13.4.2    compensated for by the operation of Clause 11 (Taxes);

           13.4.3    attributable to any change in the rate of tax on the
                     overall net income of the Bank (or the overall net income
                     of a division or branch of the Bank) imposed in the
                     jurisdiction in which its principal office or the relevant
                     lending office for the time being is situate;

           13.4.4    payable to an assignee or transferee of the Bank at the
                     time of an assignment, transfer or novation under Clause 25
                     (Changes to the


<PAGE>   23

                     Parties), but only to the extent that the increased cost
                     would not have been payable to the assigning, transferring
                     or novating Bank; or

           13.4.5    which is attributable to the introduction of the euro other
                     than an increased cost which is being incurred generally by
                     banks transacting euro business in the London interbank
                     market.

14.        ILLEGALITY

14.1       If it is or becomes unlawful for the Bank to give effect to any of
           its obligations as contemplated by this Agreement or to fund or
           maintain any Advance, then the Bank shall notify the Company
           accordingly and on the Maturity Date of each relevant Advance (or
           such earlier date as the relevant law or directive may require) the
           relevant Borrower shall repay or prepay, as the case may be, any
           Advances made to it by the Bank together with all other amounts
           payable by it to the Bank under this Agreement.

14.2       The Bank's Commitment shall be cancelled on the date of a
           notification under Clause 14.1 above.

15.        TAXES AND INCREASED COSTS - ADDITIONAL RIGHTS

           PREPAYMENT AND CANCELLATIONS

15.1       If any Borrower is required to pay any additional amounts to the Bank
           under Clause 11 (Taxes) or compensation under Clause 13 (Increased
           Costs), the Company may, whilst the circumstances giving rise to the
           requirement continue, serve a notice of prepayment and cancellation
           in relation to all or all affected Advances on the Bank.

15.2       On the tenth Business Day after the date of service of the notice the
           relevant Borrower shall prepay the relevant Advance or Advances made
           to it by the Bank together with all other amounts in relation to such
           Advance(s) payable by it to the Bank under this Agreement.

15.3       To the extent of the Advances referred to in the notice of prepayment
           and cancellation, but not further or otherwise, the Bank's Commitment
           shall be cancelled on the date of service of the notice.

           MITIGATION

15.4       If, in respect of the Bank, circumstances arise which would or would,

           reasonably practicable and/or transferring its rights and obligations
           under this Agreement to another bank or financial institution

                     referred to in Clause 15.4 above); or

           15.5.2    require the Bank to take any action which, in its opinion,

           except that if any of the events specified in Clauses 18.6 to 18.13
           (inclusive) occurs in relation to a Material Subsidiary which is not
           a Borrower it will only be an Event of Default if the event is, in
           the reasonable opinion of the Bank, reasonably likely to affect
           materially and adversely the Company's ability to perform its
           obligations under this Agreement.

           NON-PAYMENT

18.2       Any Borrower defaults in payment on the due date of any amount

           not remedied within seven Business Days after the Bank gives notice
           to the Company and the relevant Borrower of the default.

           BREACH OF OTHER OBLIGATIONS

18.3       Any Borrower fails to observe or perform any other obligation on its
           part contained in this Agreement (other than those which, in the
           reasonable opinion of the Bank, are not material), and (in the case
           of a breach capable of being remedied) fails to remedy the breach
           within fourteen Business Days after the date on which the Company and
           the relevant Borrower receive notice of the breach from the Bank.

           MISREPRESENTATION

18.4       A representation, warranty or statement made or repeated in, this

           particular when made or deemed to be repeated.

           (such consent not to be unreasonably withheld or delayed) any other
           Subsidiary of the Company



<PAGE>   40

           becomes an Acceding Borrower by delivering or procuring the delivery
           to the Bank a Borrower's Accession Notice duly executed by the
           Company and the relevant Subsidiary provided that if such Subsidiary
           is not resident in the United Kingdom for tax purposes the Company
           and the Bank agree to make such amendments to this Agreement as may
           be reasonably required at the time in order to allow such Subsidiary
           to pay interest to the Bank without deduction or withholding of any
           Relevant Tax and to provide such Subsidiary with equivalent rights,
           mutatis mutandis, to those contained in Clause 11.4 (Qualifying
           Bank).

31.2       Upon delivery of a Borrower's Accession Notice, the relevant
           Subsidiary shall become an Acceding Borrower and shall, subject to
           the terms and conditions of this Agreement acquire all the rights and
           assume all the obligations of a Borrower hereunder provided that the
           Bank has confirmed to the Company that it has received, in form and
           substance satisfactory to it, all the documents set out in Part II of
           Schedule 1.

31.3       The Company undertakes that it shall procure that each Acceding
           Borrower shall provide the Bank with each of the documents listed in
           Part II of Schedule 1.

31.4       If at any time any Borrower (other than the Company) has no actual or
           contingent obligation under this Agreement, the Company may deliver a
           Borrower's Cessation Notice to the Bank in which event such Borrower
           shall forthwith cease to be a Borrower upon receipt by the Bank of
           such notice.

32.        CHANGE OF CURRENCY

32.1       If more than one currency or currency unit are at the same time
           recognised by the central bank of any country as the lawful currency
           of that country, then:

           32.1.1    any reference in this Agreement to, and any obligations
                     arising under this Agreement in, the currency of that
                     country shall be translated into, or paid in, the currency
                     unit of that country designated by the Bank acting
                     reasonably and in consultation with the Company; and

           32.1.2    any translation from one currency unit to another shall be
                     at the official rate of exchange recognised by the relevant
                     central bank for the conversion of that currency or
                     currency unit into the other, rounded up or down by the
                     Bank acting reasonably.

32.2       If a change in any currency of a country occurs, the Bank and the
           Company will negotiate in good faith in order to agree any amendments
           to this Agreement to reflect market practice at that time with regard
           to the occurrence of EMU within the European Union or any part(s) of
           it and the new currency and to put the Bank and the Borrowers in the
           same position, so far as is possible, that they would have been in if
           no change in currency had occurred.

32.3       The Bank and the Company agree that the occurrence or non-occurrence
           of EMU within the European Union or part(s) of it and/or any event or
           events associated with EMU and/or the introduction of any new
           currency in all or any



<PAGE>   41

           part of the European Union will not result in the discharge
           cancellation, rescission or termination in whole or in pat of this
           Agreement or give any party hereto the right to cancel, rescind,
           terminate or vary (other than as aforesaid) this Agreement in whole
           or in part or give rise to an Event of Default.

33.        COUNTERPARTS

           which shall be an original and all of such counterparts taken

           instrument.

34.        APPLICABLE LAW AND JURISDICTION

34.1       The law of England and Wales is the law applicable to this Agreement.

34.2       Each of the Borrowers irrevocably agrees for the benefit of the Bank
           that the courts of England shall have jurisdiction to hear and
           determine any suit, action or proceeding, and to settle any disputes,
           which may arise out of or in connection with this Agreement and, for
           such purposes, irrevocably submits to the jurisdiction of such
           courts.

34.3       Each of the Borrowers which is not incorporated in England and Wales
           agrees that the process by which any suit, action or proceeding is
           begun in England and Wales may be served on it by being delivered to
           the Company at its registered office for the time being and hereby
           appoints the Company (and the Company accepts such appointment) for
           such purposes. If the appointment of the person mentioned in this
           Clause 34.3 ceases to be effective in respect of any or all of the
           Borrowers such Borrower or Borrowers shall immediately appoint a
           further person in England and Wales to accept service of process on
           its behalf in England and Wales and, failing such appointment within
           fifteen days, the Bank acting reasonably shall be entitled to appoint
           such a person by notice to such Borrower or Borrowers. Nothing
           contained herein shall affect the right to serve process in any other
           manner permitted by law.

34.4       Each of the Borrowers irrevocably waives any objection which it might
           now or hereafter have to the courts referred to in Clause 34.2 being
           nominated as the forum to hear and determine any suit, action or
           proceeding, and to settle any disputes, which may arise out of or in
           connection with this Agreement and agrees not to claim that any such
           court is not a convenient or appropriate forum.

34.5       The submission to the jurisdiction of the courts referred to in
           Clause 34.2 shall not (and shall not be construed so as to) limit the
           right of the Bank to take proceedings against any of the Borrowers in
           any other court of competent jurisdiction nor shall the taking of
           proceedings in any one or more jurisdictions preclude the taking of
           proceedings in any other jurisdiction (whether concurrently or not)
           if and to the extent permitted by applicable law.

         NUMBER OF REQUESTS AND UTILISATIONS

         specifying the same Utilisation Date, whether or not the currencies and

3.1      Each Borrower shall apply each Utilisation made to it towards the
         general corporate purposes of the Group.

         Schedule 1 in form and substance satisfactory to the Bank.

                        Utilisation; and

                        such repayment or prepayment; or

                   (b)  the amount of the first Utilisation together with other
                        sums available to the Borrower shall be used to repay or
                        prepay the Existing Outstandings and the aggregate
                        commitments under such facility agreement cancelled on

         DEFAULT INTEREST

7.3      If any Borrower fails to pay any amount payable by it under this
         Agreement, it shall, on demand by the Bank from time to time, pay
         interest on the overdue amount from the due date up to the date of
         actual payment, after as well as before judgment, at a rate (the
         "DEFAULT RATE") determined by the Bank to be one (1) per cent. per
         annum above the higher of:

         7.3.1     the rate on the overdue amount under Clause 7.1 (Interest
                   rate) immediately before the due date (but only if the
                   overdue amount is an Advance (or part thereof) and only for
                   the period up to and including the Maturity Date of that
                   Advance); and

         7.3.2     the rate which would have been payable if the overdue amount
                   had, during the period of non-payment, constituted an Advance
                   in the currency of the overdue amount for such successive
                   Terms of such duration (not exceeding three months) as the
                   Bank may reasonably determine (each a "DESIGNATED TERM").

7.4      The default rate will be determined on the first day of, or two
         Business Days before the first day of, the relevant Designated Term, as
         appropriate.

7.5      If the Bank determines that deposits in the currency of the overdue
         amount are not at the relevant time being made available by leading
         banks in the London Interbank Market, the default rate will be
         determined by reference to the cost of funds to the Bank from whatever
         sources it may reasonably select.

7.6      Default interest shall be compounded at the end of each Designated Term
         until it is paid.

         NOTIFICATION OF RATES OF INTEREST

7.7      The Bank shall promptly notify the relevant Borrower of the
         determination of any applicable rate of interest under this Agreement.

8.       REPAYMENT AND PREPAYMENT

         REPAYMENT OF ADVANCES

8.1      Each Borrower shall repay each Advance made to it in full on its
         Maturity Date to the Bank. If an Advance (the "NEW ADVANCE") is to be
         made to a Borrower on the day on which another Advance (the "MATURING
         ADVANCE") in the same currency is due to be repaid by such Borrower
         then, subject to the terms of this Agreement and so long as the
         conditions referred to in Clause 4.2 shall have been satisfied in
         relation to the New Advance:

         8.1.1     the Maturing Advance shall be deemed to have been repaid on
                   its Maturity Date either in whole (if the New Advance is
                   equal to or greater than the Maturing Advance) or in part (if
                   the New Advance is less than the Maturing Advance); and

                                      -13-
<PAGE>   14

         8.1.2     to the extent that a Maturing Advance is so deemed to have
                   been repaid, the principal amount of the New Advance to be
                   made on such a date shall be deemed to have been credited to
                   the account of such Borrower by the Bank in accordance with
                   the terms of this Agreement and, as the case may be:

                   (a)  the Bank shall only be obliged to make available to such
                        Borrower pursuant to Clause 5.6 a principal amount equal
                        to the amount (if any) by which the New Advance exceeds
                        the Maturing Advance; or

                   (b)  such Borrower shall only be obliged to pay to the Bank
                        pursuant to this Clause 8.1 a principal amount equal to
                        the amount by which the Maturing Advance exceeds the New
                        Advance.

8.2      On the Final Maturity Date, all outstanding Advances and other sums (if
         any) then owing under this Agreement shall in any event be repaid or
         paid in full.

         PREPAYMENT OF ADVANCES

8.3      Any Borrower may, without penalty and on giving not less than 15 days'
         prior notice to the Bank, prepay all or any part of an Advance, but if
         in part, in a minimum amount of Pound Sterling 1,000,000 and an
         integral multiple of Pound Sterling 100,000 (or the comparable amount
         in any Optional Currency).

8.4      Any notice by a Borrower of prepayment under this Agreement is
         irrevocable.

8.5      Should any person or group of persons, acting either individually or in
         concert (as defined in the City Code on Take Overs and Mergers
         effective as at the date of this Agreement) otherwise than with the
         consent of the Bank acquire control of the Company (and for the purpose
         of this Clause a single person or group of persons shall have acquired
         control if it or they own or hold more than 50% (fifty per cent.) of
         the issued share capital of the Company having the right to attend and
         vote at general meetings of the Company or more than 50% (fifty per
         cent.) of such rights), then:

         8.5.1     the Company shall immediately upon becoming aware thereof
                   notify the Bank specifying the date of such acquisition and
                   the name of such person or persons acquiring control; and

         8.5.2     thereafter no Borrower shall be permitted to request an
                   Advance unless the terms of the acquisition of control of the
                   Company were approved by the Board of Directors of the
                   Company and the Maturity Date for any Advance requested falls
                   on a date not more than three months after the expiration of
                   the 30 day period referred to in Clause 8.6.

8.6      If the terms of the acquisition of control of the Company were approved
         by the Board of Directors of the Company, the Bank shall consult with
         the Company during the period of 30 days after receipt of the
         notification from the Company referred to in sub-Clause 8.5.1 and shall
         be entitled to give notice of



                                      -14-
<PAGE>   15

         continuance of the Facility provided hereunder to the Company. Upon
         receipt of such notice of continuance, the right of the Borrowers to
         request an Advance without the limitation referred to in sub-Clause
         8.5.2 shall be reinstated.

8.7      If the terms of the acquisition of control of the Company were approved
         by the Board of Directors of the Company but, at the end of the period
         of 30 days referred to in Clause 8.6 above, the Company has not
         received a notice of continuance then:

         8.7.1     the Facility shall be cancelled;

         8.7.2     any outstanding Advances with Maturity Dates falling later
                   than three months after the end of such period shall be
                   prepaid on the date falling three months after the end of
                   such period, together with accrued interest thereon up to the
                   date of payment and all other amounts payable to the Bank
                   hereunder; and

         8.7.3     any outstanding Advances with Maturity Dates falling not
                   later than three months after the end of such period shall be
                   repaid on their respective Maturity Dates.

8.8      If the terms of the acquisition of control of the Company were not
         approved by the Board of Directors of the Company, then unless the Bank
         shall have confirmed within 2 days of receipt of the notice referred to
         in sub-Clause 8.5.1 that the Facility shall be continued, the Facility
         shall be cancelled and any outstanding Advances shall be repayable on
         demand by the Bank together with accrued interest thereon up to the
         date of payment and all other amounts payable to the Bank hereunder.

8.9      Any prepayment under this Agreement shall be made together with accrued
         interest on the amount prepaid together with any amount payable to the
         Bank pursuant to Clause 22.3.

8.10     No Advance may be prepaid otherwise than in accordance with the express
         terms of this Agreement.

                   for payment on the due date in lawful money of the country of
                   that Optional Currency, in immediately available funds, or at
                   such times or in such funds as the Bank may specify to the
                   relevant Borrower as being customary at the time for the
                   settlement of transactions in the relevant currency in the
                   place for payment.

         CURRENCY

         Subject to clauses 9.6 and 9.7:

9.3      A repayment or prepayment of an Advance is payable in the currency in
         which the Advance is denominated.

9.4      Interest is payable in the currency in which the relevant amount in
         respect of which it is payable is denominated.

9.5      Any other amount payable under this Agreement is, except as otherwise
         provided in this Agreement, payable in Sterling.

9.6      Subject to clause 9.7, on and after the Commencement Date, any Advance
         requested to be denominated in the currency of a Participating Member
         State shall be made in the euro unit.

9.7      If and to the extent that any EMU legislation provides that an amount
         denominated either in the euro unit or in the national currency unit of
         a given Participating Member State and payable within that
         Participating Member State by crediting an account of the creditor, can
         be paid by the debtor either in the euro unit or in that national
         currency unit, a Party shall be entitled to pay that amount either in
         the euro unit or in the relevant national currency unit.

         SET-OFF AND COUNTERCLAIM

9.8      All payments made by each of the Borrowers under this Agreement shall
         be made without set-off or counterclaim.

         NON-BUSINESS DAYS

         PARTIAL PAYMENTS

9.11     If the Bank receives a payment insufficient to discharge all the
         amounts then due and payable by any Borrower under this Agreement, the
         Bank shall apply that payment towards the obligations of such Borrower
         under this Agreement in the following order:

                                      -16-
<PAGE>   17

         9.11.1    firstly, in or towards payment of any unpaid costs and
                   expenses of the Bank under this Agreement;

         9.11.2    secondly, in or towards payment of any accrued fees due but
                   unpaid under Clause 19.2 (Commitment Fee);

         9.11.3    thirdly, in or towards payment of any accrued interest due
                   but unpaid under this Agreement;

         9.11.4    fourthly, in or towards payment of any principal due but

9.13     Clauses 9.11 and 9.12 above shall override any appropriation made by
         any Borrower.

10.      OPTIONAL CURRENCIES

         SELECTION

10.1     No Borrower may request an Advance denominated in an Optional Currency
         unless the Bank has confirmed to such Borrower that the Optional
         Currency is readily available and freely transferable in the London
         foreign exchange market.

         CHANGE OF CURRENCY

10.2     If, on the Rate Fixing Day of an Advance to be denominated in an
         Optional Currency, the Bank determines that:

         10.2.1    it is impracticable for reasons beyond its control for the
                   Bank to fund the Advance for its Term in that Optional
                   Currency in the ordinary course of business in the London
                   Interbank Market; or

         10.2.2    the use of the proposed Optional Currency might contravene
                   any law or regulation,

         then:

         10.2.3    the Bank shall promptly and in any event before 10.30 a.m. on
                   that Rate Fixing Day notify the relevant Borrower;

         10.2.4    if the Bank receives notice from the relevant Borrower by
                   11.30 a.m. on that Rate Fixing Day to that effect, the
                   Advance will not be made; and

         10.2.5    if the Bank does not receive any notice under sub-Clause
                   10.2.4 above, the Advance will be denominated instead in
                   Sterling in an amount equal to its Original Sterling Amount.

                                      -17-
<PAGE>   18

         NOTIFICATION OF RATES AND AMOUNTS

10.3     The Bank shall, on request, promptly notify the relevant Borrower of
         any applicable Bank's Spot Rate of Exchange or Original Sterling Amount
         promptly after it has been ascertained.

10.4     If an Advance which has been drawn in an Optional Currency is
         reborrowed in the same Optional Currency immediately following its
         repayment, then the Original Sterling Amount of such new Advance
         denominated in such Optional Currency shall be recalculated for the new
         Term in accordance with the terms and conditions of this Agreement and
         if on the relevant Utilisation Date the aggregate Original Sterling
         Amount of all Advances outstanding on such date exceeds the Commitment,
         then any excess shall be repaid to the Bank by the relevant Borrower
         upon the Bank's first written demand.

11.      TAXES

         GROSS-UP

11.1     All payments by each of the Borrowers under this Agreement shall be
         made without any deductions and free and clear of and without deduction
         for or on account of any Relevant Taxes except to the extent that any
         Borrower is required by law to make payment subject to any such taxes.
         If any Relevant Tax or amounts in respect of any Relevant Tax must be
         deducted from any amounts payable or paid by any Borrower hereunder,
         such Borrower shall pay such additional amounts as may be necessary to
         ensure that the Bank receives a net amount equal to the full amount
         which it would have received had payment not been made subject to tax.

         "RELEVANT TAX" in relation to any payment which falls to be made
         hereunder means any present or future taxes of any nature now or
         hereafter imposed by the laws of (i) the United Kingdom, (ii) any other
         jurisdiction from which, or through which, such payment is made or to
         the taxation laws of which the relevant Borrower is at the time of such
         payment subject, (iii) any political sub-division of the United Kingdom
         or any such other jurisdiction or (iv) any federation or association of
         states of which the United Kingdom or any such other jurisdiction is,
         at the time of such payment, a member.

         TAX RECEIPTS

11.2     All Relevant Taxes required by law to be deducted or withheld by any
         Borrower from any amount paid or payable under this Agreement shall be
         paid by such Borrower when due (unless the obligation to pay is being
         disputed in good faith) and such Borrower shall, within 30 days of the
         payment being made, deliver to the Bank evidence satisfactory to the
         Bank (including all relevant tax receipts) that the payment has been
         duly remitted to the appropriate authority.

         TAX CREDITS

11.3     If any Borrower pays any additional amount (a "TAX PAYMENT") under
         Clause 11.1 and the Bank effectively obtains a refund of tax, or a
         relief or credit against

                                      -18-
<PAGE>   19

         tax by reason of that Tax Payment (a "TAX CREDIT"), and the Bank is
         able to identify the Tax Credit as being attributable to the Tax
         Payment, then the Bank shall reimburse to the relevant Borrower such
         amount as the Bank reasonably determines to be the proportion of the
         Tax Credit as will leave the Bank (after that reimbursement) in no
         better or worse position that it would have been if the Tax Payment had
         not been required. Nothing in this Clause interferes with the right of
         the Bank to arrange its tax affairs in whatever manner it thinks fit
         and, without prejudice to the foregoing, the Bank is under no
         obligation to claim a Tax Credit, or to claim a Tax Credit in priority
         to any other claim, relief, credit or deduction available to it. The
         Bank is not obliged to disclose any information regarding its tax
         affairs or computations to any Borrower.

         QUALIFYING BANK

11.4     If, otherwise than as a result of the introduction of, change in, or
         change in the interpretation, administration or application of, any law
         or regulation or any practice or concession of the Inland Revenue after
         the Signing Date, the Bank ceases to be a Qualifying Bank no Borrower
         shall be liable to pay to the Bank under Clause 11.1 (Gross-up) any
         amount in respect of taxes levied or imposed by the UK or any taxing
         authority thereof or therein in excess of the amount it would have been
         obliged to pay if the Bank had been or had not ceased to be a
         Qualifying Bank.

12.      MARKET DISRUPTION

         MARKET DISRUPTION

12.1     If, in relation to any proposed Utilisation:

         12.1.1    the Bank is unable to obtain from leading banks a rate for
                   the purposes of determining the applicable LIBOR or the Bank
                   otherwise determines that adequate and fair means do not
                   exist for ascertaining the applicable LIBOR; or

         12.1.2    in the opinion of the Bank:

                   (a)  matching deposits may not be available to it in the
                        London Interbank Market in the ordinary course of
                        business to fund an Advance; or

                   (b)  the cost to it of matching deposits in the London
                        Interbank Market would be in excess of the relevant
                        LIBOR,

                   the Bank shall notify the Company by 10.30 a.m. or as soon as
                   is practicable thereafter on the Rate Fixing Day of the fact
                   and that this Clause is in operation.

12.2     After any notification under Clause 12.1 above:

         12.2.1    subject to sub-Clause 12.2.3 below the relevant Advance shall
                   be made in Sterling in an amount equal to its Original
                   Sterling Amount (unless Sterling was the original currency of
                   the relevant Advance);

                                      -19-
<PAGE>   20

         12.2.2    subject to sub-Clause 12.2.3 below, no further notices of
                   Utilisation by telephone or Requests for Advances to be
                   denominated in the original currency of the affected Advance
                   may be delivered until the Bank notifies the Company that the
                   event specified in the notification no longer prevails;

         12.2.3    the relevant Borrower may, by notice to the Bank by 11.00
                   a.m. (or, if later, within 30 minutes of receipt by the
                   Company of a notification under sub-Clause 12.1.2) on the
                   Rate Fixing Day: (i) elect for the notice of Utilisation by
                   telephone or the Request to be cancelled without penalty;
                   (ii) if the Advance was to be made in an Optional Currency,
                   elect for the Advance to be made in an Optional Currency
                   other than a currency affected by the event specified in the
                   notification or (iii) elect for the Advance to be made in
                   accordance with the Request notwithstanding the event
                   specified in the notification. If any Borrower requires an
                   affected Advance to be made in the original currency selected
                   for such Advance notwithstanding the event specified in the
                   notification then within five Business Days of receipt of the
                   notification, the Company and the Bank shall enter into
                   negotiations for a period of not more than 25 days with a
                   view to agreeing a substitute basis for determining the rate
                   of interest and/or funding applicable to the affected Advance
                   and any future Advances in the currency of the affected
                   Advance provided that if no substitute basis is agreed within
                   that period:

                   (a)  the Bank shall certify to the Company (such certificate
                        to be conclusive) the alternative interest rate

                   (b)  the certificate may make provision for different funding
                        periods and shall be retroactive to the beginning of the
                        then current Term; and

                   (c)  the certificate shall be binding on each relevant
                        Borrower unless the Company gives notice to the Bank
                        within five Business Days of the receipt of the
                        certificate that the certificate is not acceptable and
                        that each relevant Borrower shall prepay in full the
                        relevant Advances on a Business Day specified in the
                        notice, which shall be not less than five nor more than
                        thirty days after the date of the Bank's certificate to
                        the Company; and

         12.2.4    for the purposes of sub-Clause 12.2.3(a) above the rate of
                   interest on each Advance shall be the rate certified by the
                   Bank as the rate per annum determined by the Bank to be the
                   aggregate of:

                   (a)  the Margin;

                   (b)  the rate notified by the Bank, on or before the last day
                        of its Term, as being the cost to the Bank of funding

12.3     During the period when any substitute basis is in force in relation to
         a particular currency, the Bank shall periodically determine whether
         the circumstances referred to in Clause 12.1 above still apply and, if
         they do not, shall forthwith give notice in writing to the Company of
         the date on which the substitute basis will cease to apply.

13.      INCREASED COSTS

         INCREASED COSTS - SERVICE OF DEMAND

13.1     If the result of any introduction of or change in any law or regulation
         after the Signing Date, or of any change in the application or
         interpretation of any such changed law or regulation or compliance by
         the Bank with any such changed law or regulation after the Signing Date
         (including, without limitation, any law or regulation relating to
         taxation, any reserve, special deposit, cash ratio, liquidity or
         capital adequacy requirement or any form of banking or monetary control
         but excluding (i) changes arising from the implementation by any
         authority having jurisdiction over the Bank or its holding company of
         the matters set out in the statement prepared by the Basle Committee on
         Banking Regulations and Supervisory Practices dated July 1988 and
         entitled "International Convergence of Capital Measurement and Capital
         Standards" (as amended in November 1991) and (ii) changes arising from
         the implementation in whole or in part by any authority having
         jurisdiction over the Bank or its holding company of the proposals
         contained in the matters set out in the EC Directive 93/6/EEC of 15
         March 1993 on the capital adequacy of investment firms and credit
         institutions) is that the Bank incurs an increased cost, then the Bank
         will promptly notify the Company of the relevant event and the Company
         shall on demand pay to the Bank such amount as the Bank certifies in
         the demand will compensate it for the applicable increased cost.

13.2     In this Clause 13 "INCREASED COST" means:

         13.2.1    an additional cost incurred by the Bank as a result of it
                   having entered into, or performing, maintaining or funding
                   its obligations under, this Agreement; or

         13.2.2    that portion of an additional cost incurred by the Bank in
                   making, funding or maintaining all or any advances comprised
                   in a class of advances formed by or including the Advances
                   made or to be made by it under this Agreement as is
                   attributable to it making, funding, or maintaining such
                   advances; or

         13.2.3    a reduction in any amount payable to the Bank or the
                   effective return to the Bank under this Agreement or on its
                   capital; or

         13.2.4    any payment made or interest or other return on or calculated
                   by reference to any amount received or receivable by the Bank
                   under this Agreement which is forgone.

<PAGE>   22

13.3     When calculating an increased cost, the Bank may allocate or spread
         costs, liabilities and losses to or across its liabilities or assets,
         or any class of liabilities or assets, and on such basis, as it
         reasonably considers appropriate.

         INCREASED COSTS - EXCEPTIONS

13.4     An increased cost does not include any increased cost:

         13.4.1    compensated for by the payment of the Mandatory Cost;

         13.4.2    compensated for by the operation of Clause 11 (Taxes);

         13.4.3    attributable to any change in the rate of tax on the overall
                   net income of the Bank (or the overall net income of a
                   division or branch of the Bank) imposed in the jurisdiction
                   in which its principal office or the relevant lending office
                   for the time being is situate;

         13.4.4    payable to an assignee or transferee of the Bank at the time
                   of an assignment, transfer or novation under Clause 25
                   (Changes to the Parties), but only to the extent that the
                   increased cost would not have been payable to the assigning,
                   transferring or novating Bank; or

         13.4.5    which is attributable to the introduction of the euro other
                   than an increased cost which is being incurred generally by
                   banks transacting euro business in the London interbank
                   market.

14.      ILLEGALITY

14.1     If it is or becomes unlawful for the Bank to give effect to any of its
         obligations as contemplated by this Agreement or to fund or maintain
         any Advance, then the Bank shall notify the Company accordingly and on
         the Maturity Date of each relevant Advance (or such earlier date as the
         relevant law or directive may require) the relevant Borrower shall
         repay or prepay, as the case may be, any Advances made to it by the
         Bank together with all other amounts payable by it to the Bank under
         this Agreement.

14.2     The Bank's Commitment shall be cancelled on the date of a notification
         under Clause 14.1 above.

15.      TAXES AND INCREASED COSTS - ADDITIONAL RIGHTS

         PREPAYMENT AND CANCELLATIONS

15.1     If any Borrower is required to pay any additional amounts to the Bank
         under Clause 11 (Taxes) or compensation under Clause 13 (Increased
         Costs), the Company may, whilst the circumstances giving rise to the
         requirement continue, serve a notice of prepayment and cancellation in
         relation to all or all affected Advances on the Bank.

15.2     On the tenth Business Day after the date of service of the notice the
         relevant Borrower shall prepay the relevant Advance or Advances made to
         it by the


                                      -22-
<PAGE>   23

         Bank together with all other amounts in relation to such Advance(s)
         payable by it to the Bank under this Agreement.

15.3     To the extent of the Advances referred to in the notice of prepayment
         and cancellation, but not further or otherwise, the Bank's Commitment
         shall be cancelled on the date of service of the notice.

         MITIGATION

15.4     If, in respect of the Bank, circumstances arise which would or would,
         with the giving of notice, result in:

         15.4.1    any additional amounts becoming payable under Clause 11
                   (Taxes); or

         15.4.2    any increased cost becoming payable under Clause 13
                   (Increased Costs); or

         15.4.3    any prepayment, payment or cancellation under Clause 14
                   (Illegality),

         then the Bank shall endeavour to take such steps as are reasonably open
         to it to mitigate or remove those circumstances (including seeking
         recovery for the account of the relevant Borrower where reasonably
         practicable and/or transferring its rights and obligations under this
         Agreement to another bank or financial institution acceptable to the
         Company).

15.5     Clause 15.4 above does not:

         15.5.1    prejudice the obligations of any Borrower under this
                   Agreement (including, without limitation, under the Clauses
                   referred to in Clause 15.4 above); or

         15.5.2    require the Bank to take any action which, in its opinion,
                   might be in any way prejudicial to it or conflict with its
                   banking policies.

18.      DEFAULT

         EVENTS OF DEFAULT

18.1     Each of the events set out in Clauses 18.2 to 18.13 (inclusive) is an
         Event of Default (whether or not caused by any reason whatsoever
         outside the control of the relevant Borrower or any other person),
         except that if any of the events specified in Clauses 18.6 to 18.13
         (inclusive) occurs in relation to a Material Subsidiary which is not a
         Borrower it will only be an Event of Default if the event is, in the
         reasonable opinion of the Bank, reasonably likely to affect materially
         and adversely the Company's ability to perform its obligations under
         this Agreement.

         NON-PAYMENT

18.2     Any Borrower defaults in payment on the due date of any amount payable
         by it under this Agreement at the place at and in the currency in which

         relevant Borrower of the default.

         BREACH OF OTHER OBLIGATIONS

18.3     Any Borrower fails to observe or perform any other obligation on its
         part contained in this Agreement (other than those which, in the
         reasonable opinion of the Bank, are not material), and (in the case of
         a breach capable of being remedied) fails to remedy the breach within
         fourteen Business Days after the date on which the Company and the
         relevant Borrower receive notice of the breach from the Bank.

         particular when made or deemed to be repeated.

         CROSS-DEFAULT

18.5     The principal amount of any Borrowings of any Borrower or Material
         Subsidiary

         18.5.1    are not paid when due (after the expiry of any applicable

31.      DESIGNATION OF ACCEDING AND SECEDING BORROWERS

31.1     The Company may request that any of its Subsidiaries incorporated in
         England and Wales and, with the prior written consent of the Bank (such
         consent not to be unreasonably withheld or delayed) any other
         Subsidiary of the Company becomes an Acceding Borrower by delivering or
         procuring the delivery to the Bank a Borrower's Accession Notice duly
         executed by the Company and the relevant Subsidiary provided that if
         such Subsidiary is not resident in the United Kingdom for tax purposes
         the Company and the Bank agree to make such amendments to this
         Agreement as may be reasonably required at the time in order to allow
         such Subsidiary to pay interest to the Bank without deduction or
         withholding of any Relevant Tax and to provide such Subsidiary with
         equivalent rights, mutatis mutandis, to those contained in Clause 11.4
         (Qualifying Bank).

31.2     Upon delivery of a Borrower's Accession Notice, the relevant Subsidiary
         shall become an Acceding Borrower and shall, subject to the terms and
         conditions of this Agreement acquire all the rights and assume all the
         obligations of a Borrower hereunder provided that the Bank has
         confirmed to the Company that it has received, in form and substance
         satisfactory to it, all the documents set out in Part II of Schedule 1.

31.3     The Company undertakes that it shall procure that each Acceding
         Borrower shall provide the Bank with each of the documents listed in
         Part II of Schedule 1.

31.4     If at any time any Borrower (other than the Company) has no actual or
         contingent obligation under this Agreement, the Company may deliver a
         Borrower's Cessation Notice to the Bank in which event such Borrower
         shall forthwith cease to be a Borrower upon receipt by the Bank of such
         notice.

32.      CHANGE OF CURRENCY

32.1     If more than one currency or currency unit are at the same time
         recognised by the central bank of any country as the lawful currency of
         that country, then:

         32.1.1    any reference in this Agreement to, and any obligations
                   arising under this Agreement in, the currency of that country
                   shall be translated into, or paid in, the currency unit of
                   that country designated by the Bank acting reasonably and in
                   consultation with the Company; and

         32.1.2    any translation from one currency unit to another shall be at
                   the official rate of exchange recognised by the relevant
                   central bank for the conversion of that currency or currency
                   unit into the other, rounded up or down by the Bank acting
                   reasonably.

32.2     If a change in any currency of a country occurs, the Bank and the
         Company will negotiate in good faith in order to agree any amendments
         to this Agreement to reflect market practice at that time with regard
         to the occurrence of EMU within the European Union or any part(s) of it
         and the new currency and to put the Bank and the Borrowers in the same
         position, so far as is possible, that they would have been in if no
         change in currency had occurred.

                                      -38-
<PAGE>   39

32.3     The Bank and the Company agree that the occurrence or non-occurrence of
         EMU within the European Union or part(s) of it and/or any event or
         events associated with EMU and/or the introduction of any new currency
         in all or any part of the European Union will not result in the
         discharge cancellation, rescission or termination in whole or in pat of
         this Agreement or give any party hereto the right to cancel, rescind,
         terminate or vary (other than as aforesaid) this Agreement in whole or
         in part or give rise to an Event of Default.

33.      COUNTERPARTS

         This Agreement may be executed in any number of counterparts each of
         which shall be an original and all of such counterparts taken together
         shall be delivered to constitute one and the same instrument.

34.      APPLICABLE LAW AND JURISDICTION

34.1     The law of England and Wales is the law applicable to this Agreement.

34.2     Each of the Borrowers irrevocably agrees for the benefit of the Bank
         that the courts of England shall have jurisdiction to hear and
         determine any suit, action or proceeding, and to settle any disputes,
         which may arise out of or in connection with this Agreement and, for
         such purposes, irrevocably submits to the jurisdiction of such courts.

34.3     Each of the Borrowers which is not incorporated in England and Wales
         agrees that the process by which any suit, action or proceeding is
         begun in England and Wales may be served on it by being delivered to
         the Company at its registered office for the time being and hereby
         appoints the Company (and the Company accepts such appointment) for
         such purposes. If the appointment of the person mentioned in this
         Clause 34.3 ceases to be effective in respect of any or all of the
         Borrowers such Borrower or Borrowers shall immediately appoint a
         further person in England and Wales to accept service of process on its
         behalf in England and Wales and, failing such appointment within
         fifteen days, the Bank acting reasonably shall be entitled to appoint
         such a person by notice to such Borrower or Borrowers. Nothing
         contained herein shall affect the right to serve process in any other
         manner permitted by law.

34.4     Each of the Borrowers irrevocably waives any objection which it might
         now or hereafter have to the courts referred to in Clause 34.2 being
         nominated as the forum to hear and determine any suit, action or
         proceeding, and to settle any disputes, which may arise out of or in
         connection with this Agreement and agrees not to claim that any such
         court is not a convenient or appropriate forum.

34.5     The submission to the jurisdiction of the courts referred to in
         Clause 34.2 shall not (and shall not be construed so as to) limit the
         right of the Bank to take proceedings against any of the Borrowers in
         any other court of competent jurisdiction nor shall the taking of
         proceedings in any one or more jurisdictions preclude the taking of
         proceedings in any other jurisdiction (whether concurrently or not)
         if and to the extent permitted by applicable law.

                                (Representations and Warranties) to be repeated
                                on those dates are correct and will be correct
                                immediately after the Utilisation; and

                     (b)        no Default is outstanding or might result from
                                the Utilisation; and

           4.2.2     the Utilisation would not cause Clause 2.2 (Overall
                     facility limit) to be contravened.

                                agreements cancelled on the day of such
                                repayment or prepayment; or

                                with other sums available to the Borrower shall
                                be used to repay or prepay the Existing
                                Outstandings and the aggregate commitments under
                                such facility agreements cancelled on the day of
                                such repayment or prepayment.

           COMPLETION OF REQUESTS

5.3        When giving a notice of Utilisation by telephone and when completing

           5.3.1     the Utilisation Date is a Business Day;

           5.3.2     only one currency is specified and that the Requested
                     Amount is:

                     (a)        if the currency is Sterling, a minimum of
                                Pound Sterling 1,000,000 and an integral
                                multiple of Pound Sterling 100,000; or

                     (b)        if the currency is Dollars, a minimum of US
                                $1,000,000 and an integral multiple of US

                     (c)        if the currency is an Optional Currency other
                                than Dollars, a minimum and integral multiple of
                                the amounts agreed between the relevant Borrower
                                and the Bank before the telephone notice of
                                Utilisation or delivery of that Request; or

                     (d)        such other amounts as the Bank and the relevant
                                Borrower may agree;

           5.3.3     only one Term is specified which:

                     (a)        does not overrun the Final Maturity Date; and

                     (b)        is a period of an approved duration or of an
                                optional duration; and

           5.3.4     the payment instructions comply with Clause 9 (Payments).

           In this Clause:

           "APPROVED DURATION" means a period of 1, 2, 3 or 6 months; and

           "OPTIONAL DURATION" means any other period not exceeding 12 months.

           SELECTION OF TERM OF OPTIONAL DURATION

5.4        If the relevant Borrower selects a Term of an optional duration, it
           may also select at the time of the telephone notice of Utilisation
           and in the relevant Request a Term of any approved duration to apply
           if the selection of a Term of an optional duration becomes
           ineffective in accordance with Clause 5.5.2.

5.5        If:

           5.5.1     the relevant Borrower requests a Term of an optional
                     duration; and

           5.5.2     the Bank notifies such Borrower not later than 10.30 a.m.
                     on the date of receipt by it of the relevant Request or
                     telephone notice of Utilisation pursuant to Clause 5.1 or
                     Clause 5.2 respectively that it does not agree to that
                     request,


                                      -11-
<PAGE>   12

           the Term for the proposed Utilisation shall be the alternative period
           specified in the telephone notice of Utilisation or the relevant
           Request or, in the absence of any alternative selection, 3 months.

           PAYMENT OF PROCEEDS

5.6        Subject to the terms of this Agreement, the Bank shall make the
           Advance available to the relevant Borrower on the relevant
           Utilisation Date.

6.         CANCELLATION

           AUTOMATIC CANCELLATION OF THE COMMITMENT

6.1        The Commitment shall be automatically;

           6.1.1     reduced to Pound Sterling 30,000,000 at close of business
                     on the third anniversary of the Signing Date and to Pound
                     Sterling 25,000,000 at the close of business on the 4th
                     anniversary of the Signing Date and the Borrower shall,
                     on or before such dates, repay and/or prepay such amount,
                     if any, as may be required to ensure that Clause 2.2
                     (Overall Facility Limit) is not contravened on such dates
                     following either of such reductions; and

           6.1.2     cancelled at close of business on the Final Maturity Date.

           VOLUNTARY CANCELLATION

6.2        The Company may, without penalty and by giving not less than 15 days'
           prior notice to the Bank, cancel the Commitment in whole or in part.

6.3        A notice of cancellation will be irrevocable and shall specify:

           6.3.1     the date on which the cancellation is to become effective;
                     and

           6.3.2     the amount of the Commitment to be cancelled.

6.4        Any cancellation may only take effect in respect of the unutilised
           portion of the Commitment as at the date the notice is to be
           effective.

           NO REINSTATEMENT

6.5        No amount of the Commitment cancelled under this Agreement may
           subsequently be reinstated.

7.         INTEREST

           INTEREST RATE

7.1        The rate of interest on each Advance for its Term is the rate per
           annum determined by the Bank to be the aggregate of the applicable:

           7.1.1     Margin,


                                      -12-
<PAGE>   13


           7.1.2     LIBOR; and

           7.1.3     Mandatory Costs.

           DUE DATES

7.2        Except as otherwise provided in this Agreement, accrued interest on
           each Advance is payable on its Maturity Date and also, in the case of
           an Advance with a term longer than six months, on the date falling
           six months after its Utilisation Date.

           DEFAULT INTEREST

7.3        If any Borrower fails to pay any amount payable by it under this
           Agreement, it shall, on demand by the Bank from time to time, pay
           interest on the overdue amount from the due date up to the date of
           actual payment, after as well as before judgment, at a rate (the
           "DEFAULT RATE") determined by the Bank to be one (1) per cent. per
           annum above the higher of:

           7.3.1     the rate on the overdue amount under Clause 7.1 (Interest
                     rate) immediately before the due date (but only if the
                     overdue amount is an Advance (or part thereof) and only for
                     the period up to and including the Maturity Date of that
                     Advance); and

           7.3.2     the rate which would have been payable if the overdue
                     amount had, during the period of non-payment, constituted
                     an Advance in the currency of the overdue amount for such
                     successive Terms of such duration (not exceeding three
                     months) as the Bank may reasonably determine (each a
                     "DESIGNATED TERM").

7.4        The default rate will be determined on the first day of, or two
           Business Days before the first day of, the relevant Designated Term,
           as appropriate.

7.5        If the Bank determines that deposits in the currency of the overdue
           amount are not at the relevant time being made available by leading
           banks in the London Interbank Market, the default rate will be
           determined by reference to the cost of funds to the Bank from
           whatever sources it may reasonably select.

7.6        Default interest shall be compounded at the end of each Designated
           Term until it is paid.

           NOTIFICATION OF RATES OF INTEREST

7.7        The Bank shall promptly notify the relevant Borrower of the
           determination of any applicable rate of interest under this
           Agreement.

8.         REPAYMENT AND PREPAYMENT

           REPAYMENT OF ADVANCES

8.1        Each Borrower shall repay each Advance made to it in full on its
           Maturity Date to the Bank. If an Advance (the "NEW ADVANCE") is to be
           made to a



                                      -13-
<PAGE>   14

           Borrower on the day on which another Advance (the "MATURING ADVANCE")
           in the same currency is due to be repaid by such Borrower then,
           subject to the terms of this Agreement and so long as the conditions
           referred to in Clause 4.2 shall have been satisfied in relation to
           the New Advance:

           8.1.1     the Maturing Advance shall be deemed to have been repaid on
                     its Maturity Date either in whole (if the New Advance is
                     equal to or greater than the Maturing Advance) or in part
                     (if the New Advance is less than the Maturing Advance); and

           8.1.2     to the extent that a Maturing Advance is so deemed to have
                     been repaid, the principal amount of the New Advance to be
                     made on such a date shall be deemed to have been credited
                     to the account of such Borrower by the Bank in accordance
                     with the terms of this Agreement and, as the case may be:

                     (a)        the Bank shall only be obliged to make available
                                to such Borrower pursuant to Clause 5.6 a
                                principal amount equal to the amount (if any) by
                                which the New Advance exceeds the Maturing
                                Advance; or

                     (b)        such Borrower shall only be obliged to pay to
                                the Bank pursuant to this Clause 8.1 a principal
                                amount equal to the amount by which the Maturing
                                Advance exceeds the New Advance.

8.2        On the Final Maturity Date, all outstanding Advances and other sums
           (if any) then owing under this Agreement shall in any event be repaid
           or paid in full.

           PREPAYMENT OF ADVANCES

8.3        Any Borrower may, without penalty and on giving not less than 15
           days' prior notice to the Bank, prepay all or any part of an Advance,
           but if in part, in a minimum amount of Pound Sterling 1,000,000 and
           an integral multiple of Pound Sterling 100,000 (or the comparable
           amount in any Optional Currency).

8.4        Any notice by a Borrower of prepayment under this Agreement is
           irrevocable.

8.5        Should any person or group of persons, acting either individually or
           in concert (as defined in the City Code on Take Overs and Mergers
           effective as at the date of this Agreement) otherwise than with the
           consent of the Bank acquire control of the Company (and for the
           purpose of this Clause a single person or group of persons shall have
           acquired control if it or they own or hold more than 50% (fifty per
           cent.) of the issued share capital of the Company having the right to
           attend and vote at general meetings of the Company or more than 50%
           (fifty per cent.) of such rights), then:

           8.5.1     the Company shall immediately upon becoming aware thereof
                     notify the Bank specifying the date of such acquisition and
                     the name of such person or persons acquiring control; and

           8.5.2     thereafter no Borrower shall be permitted to request an
                     Advance unless the terms of the acquisition of control of
                     the Company were


                                      -14-
<PAGE>   15

                     approved by the Board of Directors of the Company and the
                     Maturity Date for any Advance requested falls on a date not
                     more than three months after the expiration of the 30 day
                     period referred to in Clause 8.6.

8.6        If the terms of the acquisition of control of the Company were
           approved by the Board of Directors of the Company, the Bank shall
           consult with the Company during the period of 30 days after receipt
           of the notification from the Company referred to in sub-Clause 8.5.1
           and shall be entitled to give notice of continuance of the Facility
           provided hereunder to the Company. Upon receipt of such notice of
           continuance, the right of the Borrowers to request an Advance without
           the limitation referred to in sub-Clause 8.5.2 shall be reinstated.

8.7        If the terms of the acquisition of control of the Company were
           approved by the Board of Directors of the Company but, at the end of
           the period of 30 days referred to in Clause 8.6 above, the Company
           has not received a notice of continuance then:

           8.7.1     the Facility shall be cancelled;

           8.7.2     any outstanding Advances with Maturity Dates falling later
                     than three months after the end of such period shall be
                     prepaid on the date falling three months after the end of
                     such period, together with accrued interest thereon up to
                     the date of payment and all other amounts payable to the
                     Bank hereunder; and

           8.7.3     any outstanding Advances with Maturity Dates falling not
                     later than three months after the end of such period shall
                     be repaid on their respective Maturity Dates.

8.8        If the terms of the acquisition of control of the Company were not
           approved by the Board of Directors of the Company, then unless the
           Bank shall have confirmed within 2 days of receipt of the notice
           referred to in sub-Clause 8.5.1 that the Facility shall be continued,
           the Facility shall be cancelled and any outstanding Advances shall be
           repayable on demand by the Bank together with accrued interest
           thereon up to the date of payment and all other amounts payable to
           the Bank hereunder.

8.9        Any prepayment under this Agreement shall be made together with
           accrued interest on the amount prepaid together with any amount
           payable to the Bank pursuant to Clause 22.3.

8.10       No Advance may be prepaid otherwise than in accordance with the
           express terms of this Agreement.

                     country of that Optional Currency, in immediately available
                     funds, or at such times or in such funds as the Bank may
                     specify to the relevant Borrower as being customary at the
                     time for the settlement of transactions in the relevant
                     currency in the place for payment.

           CURRENCY

           Subject to clauses 9.6 and 9.7:

9.3        A repayment or prepayment of an Advance is payable in the currency in
           which the Advance is denominated.

9.4        Interest is payable in the currency in which the relevant amount in
           respect of which it is payable is denominated.

9.5        Any other amount payable under this Agreement is, except as otherwise
           provided in this Agreement, payable in Sterling.

9.6        Subject to clause 9.7, on and after the Commencement Date, any
           Advance requested to be denominated in the currency of a
           Participating Member State shall be made in the euro unit.

9.7        If and to the extent that any EMU legislation provides that an amount
           denominated either in the euro unit or in the national currency unit
           of a given Participating Member State and payable within that
           Participating Member State by crediting an account of the creditor,
           can be paid by the debtor either in the euro unit or in that national
           currency unit, a Party shall be entitled to pay that amount either in
           the euro unit or in the relevant national currency unit.

           SET-OFF AND COUNTERCLAIM

9.8        All payments made by each of the Borrowers under this Agreement shall
           be made without set-off or counterclaim.

           NON-BUSINESS DAYS

9.9        If a payment under this Agreement is due on a day which is not a
           Business Day, then the due date for the payment shall instead be the
           next Business Day.

9.10       During any extension of the due date for payment of any principal
           under this Agreement pursuant to Clause 9.9 above interest is payable
           on the principal at the rate payable on the original due date.

           PARTIAL PAYMENTS

9.11       If the Bank receives a payment insufficient to discharge all the
           amounts then due and payable by any Borrower under this Agreement,
           the Bank shall apply that payment towards the obligations of such
           Borrower under this Agreement in the following order:

           9.11.1    firstly, in or towards payment of any unpaid costs and
                     expenses of the Bank under this Agreement;

           9.11.2    secondly, in or towards payment of any accrued fees due but
                     unpaid under Clause 19.1 (Commitment Fee);

           9.11.3    thirdly, in or towards payment of any accrued interest due
                     but unpaid under this Agreement;

           9.11.4    fourthly, in or towards payment of any principal due but
                     unpaid under this Agreement, and

           9.11.5    fifthly, in or towards payment of any other sum due but
                     unpaid under this Agreement.

9.12       The Bank may vary the order set out in Clauses 9.11.1 to 9.11.5
           above.

9.13       Clauses 9.11 and 9.12 above shall override any appropriation made by
           any Borrower.

10.        OPTIONAL CURRENCIES

           SELECTION

10.1       No Borrower may request an Advance denominated in an Optional
           Currency unless the Bank has confirmed to such Borrower that the
           Optional Currency is readily available and freely transferable in the
           London foreign exchange market.

           CHANGE OF CURRENCY

10.2       If, on the Rate Fixing Day of an Advance to be denominated in an
           Optional Currency, the Bank determines that:

           10.2.1    it is impracticable for reasons beyond its control for the
                     Bank to fund the Advance for its Term in that Optional
                     Currency in the ordinary course of business in the London
                     Interbank Market; or

           10.2.2    the use of the proposed Optional Currency might contravene
                     any law or regulation,



                                      -17-
<PAGE>   18


           then:

           10.2.3    the Bank shall promptly and in any event before 10.30 a.m.
                     on that Rate Fixing Day notify the relevant Borrower;

           10.2.4    if the Bank receives notice from the relevant Borrower by
                     11.30 a.m. on that Rate Fixing Day to that effect, the
                     Advance will not be made; and

           10.2.5    if the Bank does not receive any notice under sub-Clause
                     10.2.4 above, the Advance will be denominated instead in
                     Sterling in an amount equal to its Original Sterling
                     Amount.

           NOTIFICATION OF RATES AND AMOUNTS

10.3       The Bank shall, on request, promptly notify the relevant Borrower of
           any applicable Bank's Spot Rate of Exchange or Original Sterling
           Amount promptly after it has been ascertained.

10.4       If an Advance which has been drawn in an Optional Currency is
           reborrowed in the same Optional Currency immediately following its
           repayment, then the Original Sterling Amount of such new Advance
           denominated in such Optional Currency shall be recalculated for the
           new Term in accordance with the terms and conditions of this
           Agreement and if on the relevant Utilisation Date the aggregate
           Original Sterling Amount of all Advances outstanding on such date
           exceeds the Commitment, then any excess shall be repaid to the Bank
           by the relevant Borrower upon the Bank's first written demand.

11.        TAXES

           GROSS-UP

11.1       All payments by each of the Borrowers under this Agreement shall be
           made without any deductions and free and clear of and without
           deduction for or on account of any Relevant Taxes except to the
           extent that any Borrower is required by law to make payment subject
           to any such taxes. If any Relevant Tax or amounts in respect of any
           Relevant Tax must be deducted from any amounts payable or paid by any
           Borrower hereunder, such Borrower shall pay such additional amounts
           as may be necessary to ensure that the Bank receives a net amount
           equal to the full amount which it would have received had payment not
           been made subject to tax.

           "RELEVANT TAX" in relation to any payment which falls to be made
           hereunder means any present or future taxes of any nature now or
           hereafter imposed by the laws of (i) the United Kingdom, (ii) any
           other jurisdiction from which, or through which, such payment is made
           or to the taxation laws of which the relevant Borrower is at the time
           of such payment subject, (iii) any political sub-division of the
           United Kingdom or any such other jurisdiction or (iv) any federation
           or association of states of which the United Kingdom or any such
           other jurisdiction is, at the time of such payment, a member.

           TAX RECEIPTS

11.2       All Relevant Taxes required by law to be deducted or withheld by any
           Borrower from any amount paid or payable under this Agreement shall
           be paid by such Borrower when due (unless the obligation to pay is
           being disputed in good faith) and such Borrower shall, within 30 days
           of the payment being made, deliver to the Bank evidence satisfactory
           to the Bank (including all relevant tax receipts) that the payment
           has been duly remitted to the appropriate authority.

           TAX CREDITS

11.3       If any Borrower pays any additional amount (a "TAX PAYMENT") under
           Clause 11.1 and the Bank effectively obtains a refund of tax, or a
           relief or credit against tax by reason of that Tax Payment (a "TAX
           CREDIT"), and the Bank is able to identify the Tax Credit as being
           attributable to the Tax Payment, then the Bank shall reimburse to the
           relevant Borrower such amount as the Bank reasonably determines to be
           the proportion of the Tax Credit as will leave the Bank (after that
           reimbursement) in no better or worse position that it would have been
           if the Tax Payment had not been required. Nothing in this Clause
           interferes with the right of the Bank to arrange its tax affairs in
           whatever manner it thinks fit and, without prejudice to the
           foregoing, the Bank is under no obligation to claim a Tax Credit, or
           to claim a Tax Credit in priority to any other claim, relief, credit
           or deduction available to it. The Bank is not obliged to disclose any
           information regarding its tax affairs or computations to any
           Borrower.

           QUALIFYING BANK

11.4       If, otherwise than as a result of the introduction of, change in, or
           change in the interpretation, administration or application of, any
           law or regulation or any practice or concession of the Inland Revenue
           after the Signing Date, the Bank ceases to be a Qualifying Bank no
           Borrower shall be liable to pay to the Bank under Clause 11.1
           (Gross-up) any amount in respect of taxes levied or imposed by the UK
           or any taxing authority thereof or therein in excess of the amount it
           would have been obliged to pay if the Bank had been or had not ceased
           to be a Qualifying Bank.

12.        MARKET DISRUPTION

           MARKET DISRUPTION

12.1       If, in relation to any proposed Utilisation:

           12.1.1    the Bank is unable to obtain from leading banks a rate for
                     the purposes of determining the applicable LIBOR or the
                     Bank otherwise determines that adequate and fair means do
                     not exist for ascertaining the applicable LIBOR; or

           12.1.2    in the opinion of the Bank:



                                      -19-
<PAGE>   20

                     (a)        matching deposits may not be available to it in
                                the London Interbank Market in the ordinary
                                course of business to fund an Advance; or

                     (b)        the cost to it of matching deposits in the
                                London Interbank Market would be in excess of
                                the relevant LIBOR,

                     the Bank shall notify the Company by 10.30 a.m. or as soon
                     as is practicable thereafter on the Rate Fixing Day of the
                     fact and that this Clause is in operation.

12.2       After any notification under Clause 12.1 above:

           12.2.1    subject to sub-Clause 12.2.3 below the relevant Advance
                     shall be made in Sterling in an amount equal to its
                     Original Sterling Amount (unless Sterling was the original
                     currency of the relevant Advance);

           12.2.2    subject to sub-Clause 12.2.3 below, no further notices of
                     Utilisation by telephone or Requests for Advances to be
                     denominated in the original currency of the affected
                     Advance may be delivered until the Bank notifies the
                     Company that the event specified in the notification no
                     longer prevails;

           12.2.3     the relevant Borrower may, by notice to the Bank by 11.00
                     a.m. (or, if later, within 30 minutes of receipt by the
                     Company of a notification under sub-Clause 12.1.2) on the
                     Rate Fixing Day: (i) elect for the notice of Utilisation by
                     telephone or the Request to be cancelled without penalty;
                     (ii) if the Advance was to be made in an Optional Currency,
                     elect for the Advance to be made in an Optional Currency
                     other than a currency affected by the event specified in
                     the notification or (iii) elect for the Advance to be made
                     in accordance with the Request notwithstanding the event
                     specified in the notification. If any Borrower requires an
                     affected Advance to be made in the original currency
                     selected for such Advance notwithstanding the event
                     specified in the notification then within five Business
                     Days of receipt of the notification, the Company and the
                     Bank shall enter into negotiations for a period of not more
                     than 25 days with a view to agreeing a substitute basis for
                     determining the rate of interest and/or funding applicable
                     to the affected Advance and any future Advances in the
                     currency of the affected Advance provided that if no
                     substitute basis is agreed within that period:

                     (a)        the Bank shall certify to the Company (such
                                certificate to be conclusive) the alternative
                                interest rate calculated in accordance with
                                sub-Clause 12.2.4 below;

                     (b)        the certificate may make provision for different
                                funding periods and shall be retroactive to the
                                beginning of the then current Term; and

                     (c)        the certificate shall be binding on each
                                relevant Borrower unless the Company gives
                                notice to the Bank within five



                                      -20-
<PAGE>   21

                                Business Days of the receipt of the certificate
                                that the certificate is not acceptable and that
                                each relevant Borrower shall prepay in full the
                                relevant Advances on a Business Day specified in
                                the notice, which shall be not less than five
                                nor more than thirty days after the date of the
                                Bank's certificate to the Company; and

           12.2.4    for the purposes of sub-Clause 12.2.3(a) above the rate of
                     interest on each Advance shall be the rate certified by the
                     Bank as the rate per annum determined by the Bank to be the
                     aggregate of:

                     (a)        the Margin;

                     (b)        the rate notified by the Bank, on or before the
                                last day of its Term, as being the cost to the
                                Bank of funding the Advance from such other
                                sources as it may reasonably select; and

                     (c)        the applicable Mandatory Cost if any.

12.3       During the period when any substitute basis is in force in relation
           to a particular currency, the Bank shall periodically determine
           whether the circumstances referred to in Clause 12.1 above still
           apply and, if they do not, shall forthwith give notice in writing to
           the Company of the date on which the substitute basis will cease to
           apply.

13.        INCREASED COSTS

           INCREASED COSTS - SERVICE OF DEMAND

13.1       If the result of any introduction of or change in any law or
           regulation after the Signing Date, or of any change in the
           application or interpretation of any such changed law or regulation
           or compliance by the Bank with any such changed law or regulation
           after the Signing Date (including, without limitation, any law or
           regulation relating to taxation, any reserve, special deposit, cash
           ratio, liquidity or capital adequacy requirement or any form of
           banking or monetary control but excluding (i) changes arising from
           the implementation by any authority having jurisdiction over the Bank
           or its holding company of the matters set out in the statement
           prepared by the Basle Committee on Banking Regulations and
           Supervisory Practices dated July 1988 and entitled "International
           Convergence of Capital Measurement and Capital Standards" (as amended
           in November 1991) and (ii) changes arising from the implementation in
           whole or in part by any authority having jurisdiction over the Bank
           or its holding company of the proposals contained in the matters set
           out in the EC Directive 93/6/EEC of 15 March 1993 on the capital
           adequacy of investment firms and credit institutions) is that the
           Bank incurs an increased cost, then the Bank will promptly notify the
           Company of the relevant event and the Company shall on demand pay to
           the Bank such amount as the Bank certifies in the demand will
           compensate it for the applicable increased cost.

13.2       In this Clause 13 "INCREASED COST" means:


                                      -21-
<PAGE>   22

           13.2.1    an additional cost incurred by the Bank as a result of it
                     having entered into, or performing, maintaining or funding
                     its obligations under, this Agreement; or

           13.2.2    that portion of an additional cost incurred by the Bank in
                     making, funding or maintaining all or any advances
                     comprised in a class of advances formed by or including the
                     Advances made or to be made by it under this Agreement as
                     is attributable to it making, funding, or maintaining such
                     advances; or

           13.2.3    a reduction in any amount payable to the Bank or the
                     effective return to the Bank under this Agreement or on its
                     capital; or

           13.2.4    any payment made or interest or other return on or
                     calculated by reference to any amount received or
                     receivable by the Bank under this Agreement which is
                     forgone.

13.3       When calculating an increased cost, the Bank may allocate or spread
           costs, liabilities and losses to or across its liabilities or assets,
           or any class of liabilities or assets, and on such basis, as it
           reasonably considers appropriate.

           INCREASED COSTS - EXCEPTIONS

           13.4.4    payable to an assignee or transferee of the Bank at the
                     time of an assignment, transfer or novation under Clause 25
                     (Changes to the Parties), but only to the extent that the
                     increased cost would not have been payable to the
                     assigning, transferring or novating Bank; or

           13.4.5    which is attributable to the introduction of the euro other
                     than an increased cost which is being incurred generally by
                     banks transacting euro business in the London interbank
                     market.

14.        ILLEGALITY

14.1       If it is or becomes unlawful for the Bank to give effect to any of
           its obligations as contemplated by this Agreement or to fund or
           maintain any Advance, then the Bank shall notify the Company
           accordingly and on the Maturity Date of each relevant Advance (or
           such earlier date as the relevant law or directive may require) the
           relevant Borrower shall repay or prepay, as the case may be, any
           Advances made to it by the Bank together with all other amounts
           payable by it to the Bank under this Agreement.

15.        TAXES AND INCREASED COSTS - ADDITIONAL RIGHTS

           PREPAYMENT AND CANCELLATIONS

15.1       If any Borrower is required to pay any additional amounts to the Bank
           under Clause 11 (Taxes) or compensation under Clause 13 (Increased
           Costs), the Company may, whilst the circumstances giving rise to the
           requirement continue, serve a notice of prepayment and cancellation
           in relation to all or all affected Advances on the Bank.

15.2       On the tenth Business Day after the date of service of the notice the
           relevant Borrower shall prepay the relevant Advance or Advances made
           to it by the Bank together with all other amounts in relation to such
           Advance(s) payable by it to the Bank under this Agreement.

15.3       To the extent of the Advances referred to in the notice of prepayment
           and cancellation, but not further or otherwise, the Bank's Commitment
           shall be cancelled on the date of service of the notice.

           MITIGATION

15.4       If, in respect of the Bank, circumstances arise which would or would,
           with the giving of notice, result in:

           15.4.1    any additional amounts becoming payable under Clause 11
                     (Taxes); or

           15.4.2    any increased cost becoming payable under Clause 13
                     (Increased Costs); or

           15.4.3    any prepayment, payment or cancellation under Clause 14
                     (Illegality),

           then the Bank shall endeavour to take such steps as are reasonably
           open to it to mitigate or remove those circumstances (including
           seeking recovery for the account of the relevant Borrower where
           reasonably practicable and/or transferring its rights and obligations
           under this Agreement to another bank or financial institution
           acceptable to the Company).

15.5       Clause 15.4 above does not:

           15.5.1    prejudice the obligations of any Borrower under this
                     Agreement (including, without limitation, under the Clauses
                     referred to in Clause 15.4 above); or

           15.5.2    require the Bank to take any action which, in its opinion,
                     might be in any way prejudicial to it or conflict with its
                     banking policies.

           17.8.1    the asset(s) so disposed of in any such single transaction
                     have a net book value exceeding 10 per cent. of

           EVENTS OF DEFAULT

18.1       Each of the events set out in Clauses 18.2 to 18.13 (inclusive) is an
           Event of Default (whether or not caused by any reason whatsoever
           outside the control of the relevant Borrower or any other person),
           except that if any of the events specified in Clauses 18.6 to 18.13
           (inclusive) occurs in relation to a Material Subsidiary which is not
           a Borrower it will only be an Event of Default if the event is, in
           the reasonable opinion of the Bank, reasonably likely to affect
           materially and adversely the Company's ability to perform its
           obligations under this Agreement.

           NON-PAYMENT

18.2       Any Borrower defaults in payment on the due date of any amount
           payable by it under this Agreement at the place at and in the

           not remedied within seven Business Days after the Bank gives notice
           to the Company and the relevant Borrower of the default.

18.3       Any Borrower fails to observe or perform any other obligation on its
           part contained in this Agreement (other than those which, in the

           of a breach capable of being remedied) fails to remedy the breach
           within fourteen Business Days after the date on which the Company and
           the relevant Borrower receive notice of the breach from the Bank.

           MISREPRESENTATION

18.4       A representation, warranty or statement made or repeated in, this

           currencies).

           INSOLVENCY

18.6       Any Borrower or Material Subsidiary is, or is deemed for the purposes
           of any law to be, unable to pay its debts generally as they fall due

           they fall due; or

18.7       Any Borrower or Material Subsidiary suspends making payments on all
           or any class of its debts or announces an intention to do so, or a

           England and Wales and, with the prior written consent of the Bank
           (such consent not to be unreasonably withheld or delayed) any other

<PAGE>   39

           Bank a Borrower's Accession Notice duly executed by the Company and
           the relevant Subsidiary provided that if such Subsidiary is not
           resident in the United Kingdom for tax purposes the Company and the
           Bank agree to make such amendments to this Agreement as may be
           reasonably required at the time in order to allow such Subsidiary to
           pay interest to the Bank without deduction or withholding of any
           Relevant Tax and to provide such Subsidiary with equivalent rights,
           mutatis mutandis, to those contained in Clause 11.4 (Qualifying
           Bank).

31.2       Upon delivery of a Borrower's Accession Notice, the relevant
           Subsidiary shall become an Acceding Borrower and shall, subject to
           the terms and conditions of this Agreement acquire all the rights and
           assume all the obligations of a Borrower hereunder provided that the
           Bank has confirmed to the Company that it has received, in form and
           substance satisfactory to it, all the documents set out in Part II of
           Schedule 1.

31.3       The Company undertakes that it shall procure that each Acceding
           Borrower shall provide the Bank with each of the documents listed in
           Part II of Schedule 1.

31.4       If at any time any Borrower (other than the Company) has no actual or
           contingent obligation under this Agreement, the Company may deliver a
           Borrower's Cessation Notice to the Bank in which event such Borrower
           shall forthwith cease to be a Borrower upon receipt by the Bank of
           such notice.

32.        CHANGE OF CURRENCY

32.1       If more than one currency or currency unit are at the same time
           recognised by the central bank of any country as the lawful currency
           of that country, then:

           32.1.1    any reference in this Agreement to, and any obligations
                     arising under this Agreement in, the currency of that
                     country shall be translated into, or paid in, the currency
                     unit of that country designated by the Bank acting
                     reasonably and in consultation with the Company; and

           32.1.2    any translation from one currency unit to another shall be
                     at the official rate of exchange recognised by the relevant
                     central bank for the conversion of that currency or
                     currency unit into the other, rounded up or down by the
                     Bank acting reasonably.

32.2       If a change in any currency of a country occurs, the Bank and the
           Company will negotiate in good faith in order to agree any amendments
           to this Agreement to reflect market practice at that time with regard
           to the occurrence of EMU within the European Union or any part(s) of
           it and the new currency and to put the Bank and the Borrowers in the
           same position, so far as is possible, that they would have been in if
           no change in currency had occurred.

32.3       The Bank and the Company agree that the occurrence or non-occurrence
           of EMU within the European Union or part(s) of it and/or any event or
           events associated with EMU and/or the introduction of any new
           currency in all or any part of the European Union will not result in
           the discharge cancellation, rescission or termination in whole or in
           pat of this Agreement or give any party



                                      -39-

           hereto the right to cancel, rescind, terminate or vary (other than as
           aforesaid) this Agreement in whole or in part or give rise to an
           Event of Default.

33.        COUNTERPARTS

           This Agreement may be executed in any number of counterparts each of
           which shall be an original and all of such counterparts taken
           together shall be delivered to constitute one and the same
           instrument.

34.        APPLICABLE LAW AND JURISDICTION

34.1       The law of England and Wales is the law applicable to this Agreement.

34.2       Each of the Borrowers irrevocably agrees for the benefit of the Bank
           that the courts of England shall have jurisdiction to hear and
           determine any suit, action or proceeding, and to settle any disputes,
           which may arise out of or in connection with this Agreement and, for
           such purposes, irrevocably submits to the jurisdiction of such
           courts.

34.3       Each of the Borrowers which is not incorporated in England and Wales
           agrees that the process by which any suit, action or proceeding is
           begun in England and Wales may be served on it by being delivered to
           the Company at its registered office for the time being and hereby
           appoints the Company (and the Company accepts such appointment) for
           such purposes. If the appointment of the person mentioned in this
           Clause 34.3 ceases to be effective in respect of any or all of the
           Borrowers such Borrower or Borrowers shall immediately appoint a
           further person in England and Wales to accept service of process on
           its behalf in England and Wales and, failing such appointment within
           fifteen days, the Bank acting reasonably shall be entitled to appoint
           such a person by notice to such Borrower or Borrowers. Nothing
           contained herein shall affect the right to serve process in any other
           manner permitted by law.

34.4       Each of the Borrowers irrevocably waives any objection which it might
           now or hereafter have to the courts referred to in Clause 34.2 being
           nominated as the forum to hear and determine any suit, action or
           proceeding, and to settle any disputes, which may arise out of or in
           connection with this Agreement and agrees not to claim that any such
           court is not a convenient or appropriate forum.

34.5       The submission to the jurisdiction of the courts referred to in
           Clause 34.2 shall not (and shall not be construed so as to) limit the
           right of the Bank to take proceedings against any of the Borrowers in
           any other court of competent jurisdiction nor shall the taking of
           proceedings in any one or more jurisdictions preclude the taking of
           proceedings in any other jurisdiction (whether concurrently or not)
           if and to the extent permitted by applicable law.

This Agreement has been entered into on the date stated at the beginning of this
Agreement.

           Signatory of the relevant Borrower.

5.2        Any Borrower may utilise the Loan Facility by notifying the Bank by
           telephone not later than 10.00 a.m. on the Rate Fixing Day provided
           that a notice given by telephone shall be confirmed in writing by the
           delivery by the relevant Borrower to the Bank of a duly completed
           Request to be actually received by the Bank not later than the close
           of business in London on the day on which such telephone notice is,
           or is deemed to have been, given.

           COMPLETION OF REQUESTS

5.3        When giving a notice of Utilisation by telephone and when completing
           the Request, the relevant Borrower must ensure that:

           5.3.1     the Utilisation Date is a Business Day;

           5.3.2     only one currency is specified and that the Requested
                     Amount is:

                     (a)        if the currency is Sterling, a minimum of Pound
                                Sterling 1,000,000 and an integral multiple of
                                Pound Sterling 100,000; or

                     (b)        if the currency is Dollars, a minimum of US
                                $1,000,000 and an integral multiple of US
                                $100,000; or

                     (c)        if the currency is an Optional Currency other
                                than Dollars, a minimum and integral multiple of
                                the amounts agreed between the relevant Borrower
                                and the Bank before the telephone notice of
                                Utilisation or delivery of that Request; or


                                      -10-
<PAGE>   11
                     (d)        such other amounts as the Bank and the relevant
                                Borrower may agree;

          5.3.3      only one Term is specified which:

                     (a)        does not overrun the Final Maturity Date; and

                     (b)        is a period of an approved duration or of an
                                optional duration; and

           5.3.4     the payment instructions comply with Clause 9 (Payments).

           In this Clause:

           "APPROVED DURATION" means a period of 1, 2, 3 or 6 months; and

           "OPTIONAL DURATION" means any other period not exceeding 6 months.

           SELECTION OF TERM OF OPTIONAL DURATION

5.4        If the relevant Borrower selects a Term of an optional duration, it
           may also select at the time of the telephone notice of Utilisation
           and in the relevant Request a Term of any approved duration to apply
           if the selection of a Term of an optional duration becomes
           ineffective in accordance with Clause 5.5.2.

5.5        If:

           5.5.1     the relevant Borrower requests a Term of an optional
                     duration; and

           5.5.2     the Bank notifies such Borrower not later than 11.30 a.m.
                     on the date of receipt by it of the relevant Request or
                     telephone notice of Utilisation pursuant to Clause 5.1 or
                     Clause 5.2 respectively that it does not agree to that
                     request,

           the Term for the proposed Utilisation shall be the alternative period
           specified in the telephone notice of Utilisation or the relevant
           Request or, in the absence of any alternative selection, 3 months.

           PAYMENT OF PROCEEDS

5.6        Subject to the terms of this Agreement, the Bank shall make the
           Advance available to the relevant Borrower on the relevant
           Utilisation Date.

6.         CANCELLATION

           AUTOMATIC CANCELLATION OF THE COMMITMENT

6.1        The Commitment shall be automatically cancelled at close of business
           on the Final Maturity Date.


                                      -11-
<PAGE>   12

           VOLUNTARY CANCELLATION

6.2        The Company may, without penalty and by giving not less than 15 days'
           prior notice to the Bank, cancel the Commitment in whole or in part.

6.3        A notice of cancellation will be irrevocable and shall specify:

           6.3.1     the date on which the cancellation is to become effective;
                     and

           6.3.2     the amount of the Commitment to be cancelled.

6.4        Any cancellation may only take effect in respect of the unutilised
           portion of the Commitment as at the date the notice is to be
           effective.

           NO REINSTATEMENT

6.5        No amount of the Commitment cancelled under this Agreement may
           subsequently be reinstated.

7.         INTEREST

           INTEREST RATE

7.1        The rate of interest on each Advance for its Term is the rate per
           annum determined by the Bank to be the aggregate of the applicable:

           7.1.1     Margin,

           7.1.2     LIBOR; and

           7.1.3     Mandatory Costs.

           DUE DATES

7.2        Except as otherwise provided in this Agreement, accrued interest on
           each Advance is payable on its Maturity Date and also, in the case of
           an Advance with a term longer than six months, on the date falling
           six months after its Utilisation Date.

           DEFAULT INTEREST

7.3        If any Borrower fails to pay any amount payable by it under this
           Agreement, it shall, on demand by the Bank from time to time, pay
           interest on the overdue amount from the due date up to the date of
           actual payment, after as well as before judgment, at a rate (the
           "DEFAULT RATE") determined by the Bank to be one (1) per cent. per
           annum above the higher of:

           7.3.1     the rate on the overdue amount under Clause 7.1 (Interest
                     rate) immediately before the due date (but only if the
                     overdue amount is an Advance (or part thereof) and only for
                     the period up to and including the Maturity Date of that
                     Advance); and


                                      -12-
<PAGE>   13

           7.3.2     the rate which would have been payable if the overdue
                     amount had, during the period of non-payment, constituted
                     an Advance in the currency of the overdue amount for such
                     successive Terms of such duration (not exceeding three
                     months) as the Bank may reasonably determine (each a
                     "DESIGNATED TERM").

7.4        The default rate will be determined on the first day of, or two
           Business Days before the first day of, the relevant Designated Term,
           as appropriate.

7.5        If the Bank determines that deposits in the currency of the overdue
           amount are not at the relevant time being made available by leading
           banks in the London Interbank Market, the default rate will be
           determined by reference to the cost of funds to the Bank from
           whatever sources it may reasonably select.

7.6        Default interest shall be compounded at the end of each Designated
           Term until it is paid.

           NOTIFICATION OF RATES OF INTEREST

7.7        The Bank shall promptly notify the relevant Borrower of the
           determination of any applicable rate of interest under this
           Agreement.

8.         REPAYMENT AND PREPAYMENT

           REPAYMENT OF ADVANCES

8.1        Each Borrower shall repay each Advance made to it in full on its
           Maturity Date to the Bank. If an Advance (the "NEW ADVANCE") is to be
           made to a Borrower on the day on which another Advance (the "MATURING
           ADVANCE") in the same currency is due to be repaid by such Borrower
           then, subject to the terms of this Agreement and so long as the
           conditions referred to in Clause 4.2 shall have been satisfied in
           relation to the New Advance:

           8.1.1     the Maturing Advance shall be deemed to have been repaid on
                     its Maturity Date either in whole (if the New Advance is
                     equal to or greater than the Maturing Advance) or in part
                     (if the New Advance is less than the Maturing Advance); and

           8.1.2     to the extent that a Maturing Advance is so deemed to have
                     been repaid, the principal amount of the New Advance to be
                     made on such a date shall be deemed to have been credited
                     to the account of such Borrower by the Bank in accordance
                     with the terms of this Agreement and, as the case may be:

                     (a)        the Bank shall only be obliged to make available
                                to such Borrower pursuant to Clause 5.6 a
                                principal amount equal to the amount (if any) by
                                which the New Advance exceeds the Maturing
                                Advance; or

                     (b)        such Borrower shall only be obliged to pay to
                                the Bank pursuant to this Clause 8.1 a principal
                                amount equal to the


                                      -13-
<PAGE>   14

                                amount by which the Maturing Advance exceeds the
                                New Advance.

8.2        On the Final Maturity Date, all outstanding Advances and other sums
           (if any) then owing under this Agreement shall in any event be repaid
           or paid in full.

           PREPAYMENT OF ADVANCES

8.3        Any Borrower may, without penalty and on giving not less than 15
           days' prior notice to the Bank, prepay all or any part of an Advance,
           but if in part, in a minimum amount of Pound Sterling 1,000,000 and
           an integral multiple of Pound Sterling 100,000 (or the comparable
           amount in any Optional Currency).

8.4        Any notice by a Borrower of prepayment under this Agreement is
           irrevocable.

8.5        Should any person or group of persons, acting either individually or
           in concert (as defined in the City Code on Take Overs and Mergers
           effective as at the date of this Agreement) otherwise than with the
           consent of the Bank acquire control of the Company (and for the
           purpose of this Clause a single person or group of persons shall have
           acquired control if it or they own or hold more than 50% (fifty per
           cent.) of the issued share capital of the Company having the right to
           attend and vote at general meetings of the Company or more than 50%
           (fifty per cent.) of such rights), then:

           8.5.1     the Company shall immediately upon becoming aware thereof
                     notify the Bank specifying the date of such acquisition and
                     the name of such person or persons acquiring control; and

           8.5.2     thereafter no Borrower shall be permitted to request an
                     Advance unless the terms of the acquisition of control of
                     the Company were approved by the Board of Directors of the
                     Company and the Maturity Date for any Advance requested
                     falls on a date not more than three months after the
                     expiration of the 30 day period referred to in Clause 8.6.

8.6        If the terms of the acquisition of control of the Company were
           approved by the Board of Directors of the Company, the Bank shall
           consult with the Company during the period of 30 days after receipt
           of the notification from the Company referred to in sub-Clause 8.5.1
           and shall be entitled to give notice of continuance of the Facility
           provided hereunder to the Company. Upon receipt of such notice of
           continuance, the right of the Borrowers to request an Advance without
           the limitation referred to in sub-Clause 8.5.2 shall be reinstated.

8.7        If the terms of the acquisition of control of the Company were
           approved by the Board of Directors of the Company but, at the end of
           the period of 30 days referred to in Clause 8.6 above, the Company
           has not received a notice of continuance then:

           8.7.1     the Facility shall be cancelled;

           8.7.2     any outstanding Advances with Maturity Dates falling later
                     than three months after the end of such period shall be
                     prepaid on the date


                                      -14-
<PAGE>   15
                     falling three months after the end of such period, together
                     with accrued interest thereon up to the date of payment and
                     all other amounts payable to the Bank hereunder; and

           8.7.3     any outstanding Advances with Maturity Dates falling not
                     later than three months after the end of such period shall
                     be repaid on their respective Maturity Dates.

8.8        If the terms of the acquisition of control of the Company were not
           approved by the Board of Directors of the Company, then unless the
           Bank shall have confirmed within 2 days of receipt of the notice
           referred to in sub-Clause 8.5.1 that the Facility shall be continued,
           the Facility shall be cancelled and any outstanding Advances shall be
           repayable on demand by the Bank together with accrued interest
           thereon up to the date of payment and all other amounts payable to
           the Bank hereunder.

8.9        Any prepayment under this Agreement shall be made together with
           accrued interest on the amount prepaid together with any amount
           payable to the Bank pursuant to Clause 22.3.

8.10       No Advance may be prepaid otherwise than in accordance with the
           express terms of this Agreement.

9.         PAYMENTS

           PLACE

9.1        All payments by each of the Borrowers or the Bank under this
           Agreement shall be made to such account at such office or bank in the
           principal financial centre of the relevant currency as it may notify
           the other or to such other place as may be agreed between the parties
           for this purpose.

           FUNDS

9.2        Payments under this Agreement shall be made:

                     place for payment on the due date in lawful money of the
                     country of that Optional Currency, in immediately available
                     funds, or at such times or in such funds as the Bank may
                     specify to the relevant Borrower as being customary at the
                     time for the settlement of transactions in the relevant
                     currency in the place for payment.

<PAGE>   16

9.3        A repayment or prepayment of an Advance is payable in the currency in

           provided in this Agreement, payable in Sterling.

           Advance requested to be denominated in the currency of a
           Participating Member State shall be made in the euro unit.

9.7        If and to the extent that any EMU legislation provides that an amount
           denominated either in the euro unit or in the national currency unit
           of a given Participating Member State and payable within that
           Participating Member State by crediting an account of the creditor,
           can be paid by the debtor either in the euro unit or in that national
           currency unit, a Party shall be entitled to pay that amount either in
           the euro unit or in the relevant national currency unit.

           SET-OFF AND COUNTERCLAIM

9.8        All payments made by each of the Borrowers under this Agreement shall
           be made without set-off or counterclaim.

           Business Day, then the due date for the payment shall instead be the
           next Business Day.

9.10       During any extension of the due date for payment of any principal
           under this Agreement pursuant to Clause 9.9 above interest is payable
           on the principal at the rate payable on the original due date.

           PARTIAL PAYMENTS

9.11       If the Bank receives a payment insufficient to discharge all the
           amounts then due and payable by any Borrower under this Agreement,
           the Bank shall apply that payment towards the obligations of such
           Borrower under this Agreement in the following order:

           9.11.1    firstly, in or towards payment of any unpaid costs and
                     expenses of the Bank under this Agreement;

           9.11.2    secondly, in or towards payment of any accrued fees due but
                     unpaid under Clause 19.2 (Commitment Fee);

           9.11.3    thirdly, in or towards payment of any accrued interest due
                     but unpaid under this Agreement;

           9.11.4    fourthly, in or towards payment of any principal due but

                                      -16-
<PAGE>   17

           9.11.5    fifthly, in or towards payment of any other sum due but
                     unpaid under this Agreement.

9.12       The Bank may vary the order set out in Clauses 9.11.1 to 9.11.5
           above.

9.13       Clauses 9.11 and 9.12 above shall override any appropriation made by
           any Borrower.

10.        OPTIONAL CURRENCIES

           SELECTION

10.1       No Borrower may request an Advance denominated in an Optional
           Currency unless the Bank has confirmed to such Borrower that the
           Optional Currency is readily available and freely transferable in the
           London foreign exchange market.

           CHANGE OF CURRENCY

10.2       If, on the Rate Fixing Day of an Advance to be denominated in an
           Optional Currency, the Bank determines that:

           10.2.1    it is impracticable for reasons beyond its control for the
                     Bank to fund the Advance for its Term in that Optional
                     Currency in the ordinary course of business in the London
                     Interbank Market; or

           10.2.2    the use of the proposed Optional Currency might contravene
                     any law or regulation, then:

           10.2.3    the Bank shall promptly and in any event before 10.30 a.m.
                     on that Rate Fixing Day notify the relevant Borrower;

           10.2.4    if the Bank receives notice from the relevant Borrower by
                     11.30 a.m. on that Rate Fixing Day to that effect, the
                     Advance will not be made; and

           10.2.5    if the Bank does not receive any notice under sub-Clause
                     10.2.4 above, the Advance will be denominated instead in
                     Sterling in an amount equal to its Original Sterling
                     Amount.

           NOTIFICATION OF RATES AND AMOUNTS

10.3       The Bank shall, on request, promptly notify the relevant Borrower of
           any applicable Bank's Spot Rate of Exchange or Original Sterling
           Amount promptly after it has been ascertained.

10.4       If an Advance which has been drawn in an Optional Currency is
           reborrowed in the same Optional Currency immediately following its
           repayment, then the Original Sterling Amount of such new Advance
           denominated in such Optional Currency shall be recalculated for the
           new Term in accordance with the terms and conditions of this
           Agreement and if on the relevant Utilisation Date the


                                      -17-
<PAGE>   18

           aggregate Original Sterling Amount of all Advances outstanding on
           such date exceeds the Commitment, then any excess shall be repaid to
           the Bank by the relevant Borrower upon the Bank's first written
           demand.

11.        TAXES

           GROSS-UP

11.1       All payments by each of the Borrowers under this Agreement shall be
           made without any deductions and free and clear of and without
           deduction for or on account of any Relevant Taxes except to the
           extent that any Borrower is required by law to make payment subject
           to any such taxes. If any Relevant Tax or amounts in respect of any
           Relevant Tax must be deducted from any amounts payable or paid by any
           Borrower hereunder, such Borrower shall pay such additional amounts
           as may be necessary to ensure that the Bank receives a net amount
           equal to the full amount which it would have received had payment not
           been made subject to tax.

           "RELEVANT TAX" in relation to any payment which falls to be made
           hereunder means any present or future taxes of any nature now or
           hereafter imposed by the laws of (i) the United Kingdom, (ii) any
           other jurisdiction from which, or through which, such payment is made
           or to the taxation laws of which the relevant Borrower is at the time
           of such payment subject, (iii) any political sub-division of the
           United Kingdom or any such other jurisdiction or (iv) any federation
           or association of states of which the United Kingdom or any such
           other jurisdiction is, at the time of such payment, a member.

           TAX RECEIPTS

11.2       All Relevant Taxes required by law to be deducted or withheld by any
           Borrower from any amount paid or payable under this Agreement shall
           be paid by such Borrower when due (unless the obligation to pay is
           being disputed in good faith) and such Borrower shall, within 30 days
           of the payment being made, deliver to the Bank evidence satisfactory
           to the Bank (including all relevant tax receipts) that the payment
           has been duly remitted to the appropriate authority.

           TAX CREDITS

11.3       If any Borrower pays any additional amount (a "TAX PAYMENT") under
           Clause 11.1 and the Bank effectively obtains a refund of tax, or a
           relief or credit against tax by reason of that Tax Payment (a "TAX
           Credit"), and the Bank is able to identify the Tax Credit as being
           attributable to the Tax Payment, then the Bank shall reimburse to the
           relevant Borrower such amount as the Bank reasonably determines to be
           the proportion of the Tax Credit as will leave the Bank (after that
           reimbursement) in no better or worse position that it would have been
           if the Tax Payment had not been required. Nothing in this Clause
           interferes with the right of the Bank to arrange its tax affairs in
           whatever manner it thinks fit and, without prejudice to the
           foregoing, the Bank is under no obligation to claim a Tax Credit, or
           to claim a Tax Credit in priority to any other claim, relief,


                                      -18-
<PAGE>   19

           credit or deduction available to it. The Bank is not obliged to
           disclose any information regarding its tax affairs or computations to
           any Borrower.

           QUALIFYING BANK

11.4       If, otherwise than as a result of the introduction of, change in, or
           change in the interpretation, administration or application of, any
           law or regulation or any practice or concession of the Inland Revenue
           after the Signing Date, the Bank ceases to be a Qualifying Bank no
           Borrower shall be liable to pay to the Bank under Clause 11.1
           (Gross-up) any amount in respect of taxes levied or imposed by the UK
           or any taxing authority thereof or therein in excess of the amount it
           would have been obliged to pay if the Bank had been or had not ceased
           to be a Qualifying Bank.

12.        MARKET DISRUPTION

           MARKET DISRUPTION

12.1       If, in relation to any proposed Utilisation:

           12.1.1    the Bank is unable to obtain from leading banks a rate for
                     the purposes of determining the applicable LIBOR or the
                     Bank otherwise determines that adequate and fair means do
                     not exist for ascertaining the applicable LIBOR; or

           12.1.2    in the opinion of the Bank:

                     (a)        matching deposits may not be available to it in
                                the London Interbank Market in the ordinary
                                course of business to fund an Advance; or

                     (b)        the cost to it of matching deposits in the
                                London Interbank Market would be in excess of
                                the relevant LIBOR,

                     the Bank shall notify the Company by 10.30 a.m. or as soon
                     as is practicable thereafter on the Rate Fixing Day of the
                     fact and that this Clause is in operation.

12.2       After any notification under Clause 12.1 above:

           12.2.1    subject to sub-Clause 12.2.3 below the relevant Advance
                     shall be made in Sterling in an amount equal to its
                     Original Sterling Amount (unless Sterling was the original
                     currency of the relevant Advance);

           12.2.2    subject to sub-Clause 12.2.3 below, no further notices of
                     Utilisation by telephone or Requests for Advances to be
                     denominated in the original currency of the affected
                     Advance may be delivered until the Bank notifies the
                     Company that the event specified in the notification no
                     longer prevails;

           12.2.3    the relevant Borrower may, by notice to the Bank by 11.00
                     a.m. (or, if later, within 30 minutes of receipt by the
                     Company of a notification


                                      -19-
<PAGE>   20

                     under sub-Clause 12.1.2) on the Rate Fixing Day: (i) elect
                     for the notice of Utilisation by telephone or the Request
                     to be cancelled without penalty; (ii) if the Advance was to
                     be made in an Optional Currency, elect for the Advance to
                     be made in an Optional Currency other than a currency
                     affected by the event specified in the notification or
                     (iii) elect for the Advance to be made in accordance with
                     the Request notwithstanding the event specified in the
                     notification. If any Borrower requires an affected Advance
                     to be made in the original currency selected for such
                     Advance notwithstanding the event specified in the
                     notification then within five Business Days of receipt of
                     the notification, the Company and the Bank shall enter into
                     negotiations for a period of not more than 25 days with a
                     view to agreeing a substitute basis for determining the
                     rate of interest and/or funding applicable to the affected
                     Advance and any future Advances in the currency of the
                     affected Advance provided that if no substitute basis is
                     agreed within that period:

                     (a)        the Bank shall certify to the Company (such
                                certificate to be conclusive) the alternative
                                interest rate calculated in accordance with
                                sub-Clause 12.2.4 below;

                     (b)        the certificate may make provision for different
                                funding periods and shall be retroactive to the
                                beginning of the then current Term; and

                     (c)        the certificate shall be binding on each
                                relevant Borrower unless the Company gives
                                notice to the Bank within five Business Days of
                                the receipt of the certificate that the
                                certificate is not acceptable and that each
                                relevant Borrower shall prepay in full the
                                relevant Advances on a Business Day specified in
                                the notice, which shall be not less than five
                                nor more than thirty days after the date of the
                                Bank's certificate to the Company; and

           12.2.4    for the purposes of sub-Clause 12.2.3(a) above the rate of
                     interest on each Advance shall be the rate certified by the
                     Bank as the rate per annum determined by the Bank to be the
                     aggregate of:

                     (a)        the Margin;

                     (b)        the rate notified by the Bank, on or before the
                                last day of its Term, as being the cost to the
                                Bank of funding the Advance from such other
                                sources as it may reasonably select; and

                     (c)        the applicable Mandatory Cost if any.

12.3       During the period when any substitute basis is in force in relation
           to a particular currency, the Bank shall periodically determine
           whether the circumstances referred to in Clause 12.1 above still
           apply and, if they do not, shall forthwith give notice in writing to
           the Company of the date on which the substitute basis will cease to
           apply.

13.        INCREASED COSTS

           INCREASED COSTS - SERVICE OF DEMAND

13.1       If the result of any introduction of or change in any law or
           regulation after the Signing Date, or of any change in the
           application or interpretation of any such changed law or regulation
           or compliance by the Bank with any such changed law or regulation
           after the Signing Date (including, without limitation, any law or
           regulation relating to taxation, any reserve, special deposit, cash
           ratio, liquidity or capital adequacy requirement or any form of
           banking or monetary control but excluding (i) changes arising from
           the implementation by any authority having jurisdiction over the Bank
           or its holding company of the matters set out in the statement
           prepared by the Basle Committee on Banking Regulations and
           Supervisory Practices dated July 1988 and entitled "International
           Convergence of Capital Measurement and Capital Standards" (as amended
           in November 1991) and (ii) changes arising from the implementation in
           whole or in part by any authority having jurisdiction over the Bank
           or its holding company of the proposals contained in the matters set
           out in the EC Directive 93/6/EEC of 15 March 1993 on the capital
           adequacy of investment firms and credit institutions) is that the
           Bank incurs an increased cost, then the Bank will promptly notify the
           Company of the relevant event and the Company shall on demand pay to
           the Bank such amount as the Bank certifies in the demand will
           compensate it for the applicable increased cost.

13.2       In this Clause 13 "INCREASED COST" means:

           13.2.1    an additional cost incurred by the Bank as a result of it
                     having entered into, or performing, maintaining or funding
                     its obligations under, this Agreement; or

           13.2.2    that portion of an additional cost incurred by the Bank in
                     making, funding or maintaining all or any advances
                     comprised in a class of advances formed by or including the
                     Advances made or to be made by it under this Agreement as
                     is attributable to it making, funding, or maintaining such
                     advances; or

           13.2.3    a reduction in any amount payable to the Bank or the
                     effective return to the Bank under this Agreement or on its
                     capital; or

           13.2.4    any payment made or interest or other return on or
                     calculated by reference to any amount received or
                     receivable by the Bank under this Agreement which is
                     forgone.

13.3       When calculating an increased cost, the Bank may allocate or spread
           costs, liabilities and losses to or across its liabilities or assets,
           or any class of liabilities or assets, and on such basis, as it
           reasonably considers appropriate.

           INCREASED COSTS - EXCEPTIONS

13.4       An increased cost does not include any increased cost:

           13.4.1    compensated for by the payment of the Mandatory Cost;


                                      -21-
<PAGE>   22

           13.4.2    compensated for by the operation of Clause 11 (Taxes);

           13.4.3    attributable to any change in the rate of tax on the
                     overall net income of the Bank (or the overall net income
                     of a division or branch of the Bank) imposed in the
                     jurisdiction in which its principal office or the relevant
                     lending office for the time being is situate;

           13.4.4    payable to an assignee or transferee of the Bank at the
                     time of an assignment, transfer or novation under Clause 25
                     (Changes to the Parties), but only to the extent that the
                     increased cost would not have been payable to the
                     assigning, transferring or novating Bank; or

           13.4.5    which is attributable to the introduction of the euro other
                     than an increased cost which is being incurred generally by
                     banks transacting euro business in the London interbank
                     market.

14.        ILLEGALITY

14.1       If it is or becomes unlawful for the Bank to give effect to any of
           its obligations as contemplated by this Agreement or to fund or
           maintain any Advance, then the Bank shall notify the Company
           accordingly and on the Maturity Date of each relevant Advance (or
           such earlier date as the relevant law or directive may require) the
           relevant Borrower shall repay or prepay, as the case may be, any
           Advances made to it by the Bank together with all other amounts
           payable by it to the Bank under this Agreement.

14.2       The Bank's Commitment shall be cancelled on the date of a
           notification under Clause 14.1 above.

15.        TAXES AND INCREASED COSTS - ADDITIONAL RIGHTS

           PREPAYMENT AND CANCELLATIONS

15.1       If any Borrower is required to pay any additional amounts to the Bank
           under Clause 11 (Taxes) or compensation under Clause 13 (Increased
           Costs), the Company may, whilst the circumstances giving rise to the
           requirement continue, serve a notice of prepayment and cancellation
           in relation to all or all affected Advances on the Bank.

15.2       On the tenth Business Day after the date of service of the notice the
           relevant Borrower shall prepay the relevant Advance or Advances made
           to it by the Bank together with all other amounts in relation to such
           Advance(s) payable by it to the Bank under this Agreement.

15.3       To the extent of the Advances referred to in the notice of prepayment
           and cancellation, but not further or otherwise, the Bank's Commitment
           shall be cancelled on the date of service of the notice.

           MITIGATION

15.4       If, in respect of the Bank, circumstances arise which would or would,
           with the giving of notice, result in:

           15.4.1    any additional amounts becoming payable under Clause 11
                     (Taxes); or

           15.4.2    any increased cost becoming payable under Clause 13
                     (Increased Costs); or

           15.4.3    any prepayment, payment or cancellation under Clause 14
                     (Illegality),

           then the Bank shall endeavour to take such steps as are reasonably
           open to it to mitigate or remove those circumstances (including
           seeking recovery for the account of the relevant Borrower where
           reasonably practicable and/or transferring its rights and obligations
           under this Agreement to another bank or financial institution
           acceptable to the Company).

18.1       Each of the events set out in Clauses 18.2 to 18.13 (inclusive) is an
           Event of Default (whether or not caused by any reason whatsoever
           outside the control of the relevant Borrower or any other person),
           except that if any of the events specified in Clauses 18.6 to 18.13
           (inclusive) occurs in relation to a Material Subsidiary which is not
           a Borrower it will only be an Event of Default if the event is, in
           the reasonable opinion of the Bank, reasonably likely to affect
           materially and adversely the Company's ability to perform its
           obligations under this Agreement.

           NON-PAYMENT

18.2       Any Borrower defaults in payment on the due date of any amount

           not remedied within seven Business Days after the Bank gives notice
           to the Company and the relevant Borrower of the default.

           BREACH OF OTHER OBLIGATIONS

18.3       Any Borrower fails to observe or perform any other obligation on its
           part contained in this Agreement (other than those which, in the
           reasonable opinion of the Bank, are not material), and (in the case
           of a breach capable of being remedied) fails to remedy the breach
           within fourteen Business Days after the date on which the Company and
           the relevant Borrower receive notice of the breach from the Bank.

           MISREPRESENTATION

18.4       A representation, warranty or statement made or repeated in, this
           Agreement by any Borrower proves to have been untrue in any material
           particular when made or deemed to be repeated.

           CROSS-DEFAULT

           Subsidiary

                     grace period); or

           18.5.2    become prematurely due and payable or are placed on demand

           they fall due; or

18.7       Any Borrower or Material Subsidiary suspends making payments on all
           or any class of its debts or announces an intention to do so, or a

           voluntary liquidation, amalgamation or reconstruction consented to by
           the Bank under Clause 18.8) ceases, or threatens to cease, to carry
           on all, or substantially all, of its business.

           ACCELERATION

                     hereunder; or

           22.7.7    any other act, event or omission including, (without
                     limitation, any amendment to this Agreement) which, but for
                     this Clause 22.7 might operate to discharge, impair or

31.        DESIGNATION OF ACCEDING AND SECEDING BORROWERS

31.1       The Company may request that any of its Subsidiaries incorporated in
           England and Wales and, with the prior written consent of the Bank
           (such consent not to be unreasonably withheld or delayed) any other
           Subsidiary of the Company becomes an Acceding Borrower by delivering
           or procuring the delivery to the Bank a Borrower's Accession Notice
           duly executed by the Company and the relevant Subsidiary provided
           that if such Subsidiary is not resident in the United Kingdom for tax
           purposes the Company and the Bank agree to make such amendments to
           this Agreement as may be reasonably required at the time in order to
           allow such Subsidiary to pay interest to the Bank without deduction
           or withholding of any Relevant Tax and to provide such Subsidiary
           with equivalent rights, mutatis mutandis, to those contained in
           Clause 11.4 (Qualifying Bank).

31.2       Upon delivery of a Borrower's Accession Notice, the relevant
           Subsidiary shall become an Acceding Borrower and shall, subject to
           the terms and conditions of this Agreement acquire all the rights and
           assume all the obligations of a Borrower hereunder provided that the
           Bank has confirmed to the Company that it has received, in form and
           substance satisfactory to it, all the documents set out in Part II of
           Schedule 1.

31.3       The Company undertakes that it shall procure that each Acceding
           Borrower shall provide the Bank with each of the documents listed in
           Part II of Schedule 1.

31.4       If at any time any Borrower (other than the Company) has no actual or
           contingent obligation under this Agreement, the Company may deliver a
           Borrower's Cessation Notice to the Bank in which event such Borrower
           shall forthwith cease to be a Borrower upon receipt by the Bank of
           such notice.

32.        CHANGE OF CURRENCY

32.1       If more than one currency or currency unit are at the same time
           recognised by the central bank of any country as the lawful currency
           of that country, then:

           32.1.1    any reference in this Agreement to, and any obligations
                     arising under this Agreement in, the currency of that
                     country shall be translated into, or paid in, the currency
                     unit of that country designated by the Bank acting
                     reasonably and in consultation with the Company; and

           32.1.2    any translation from one currency unit to another shall be
                     at the official rate of exchange recognised by the relevant
                     central bank for the conversion of that currency or
                     currency unit into the other, rounded up or down by the
                     Bank acting reasonably.

32.2       If a change in any currency of a country occurs, the Bank and the
           Company will negotiate in good faith in order to agree any amendments
           to this Agreement to reflect market practice at that time with regard
           to the occurrence of EMU within the European Union or any part(s) of
           it and the new currency and to put the Bank and the Borrowers in the
           same position, so far as is possible, that they would have been in if
           no change in currency had occurred.

<PAGE>   39

32.3       The Bank and the Company agree that the occurrence or non-occurrence
           of EMU within the European Union or part(s) of it and/or any event or
           events associated with EMU and/or the introduction of any new
           currency in all or any part of the European Union will not result in
           the discharge cancellation, rescission or termination in whole or in
           pat of this Agreement or give any party hereto the right to cancel,
           rescind, terminate or vary (other than as aforesaid) this Agreement
           in whole or in part or give rise to an Event of Default.

33.        COUNTERPARTS

           This Agreement may be executed in any number of counterparts each of
           which shall be an original and all of such counterparts taken
           together shall be delivered to constitute one and the same
           instrument.

34.        APPLICABLE LAW AND JURISDICTION

34.1       The law of England and Wales is the law applicable to this Agreement.

34.2       Each of the Borrowers irrevocably agrees for the benefit of the Bank
           that the courts of England shall have jurisdiction to hear and
           determine any suit, action or proceeding, and to settle any disputes,
           which may arise out of or in connection with this Agreement and, for
           such purposes, irrevocably submits to the jurisdiction of such
           courts.

34.3       Each of the Borrowers which is not incorporated in England and Wales
           agrees that the process by which any suit, action or proceeding is
           begun in England and Wales may be served on it by being delivered to
           the Company at its registered office for the time being and hereby
           appoints the Company (and the Company accepts such appointment) for
           such purposes. If the appointment of the person mentioned in this
           Clause 34.3 ceases to be effective in respect of any or all of the
           Borrowers such Borrower or Borrowers shall immediately appoint a
           further person in England and Wales to accept service of process on
           its behalf in England and Wales and, failing such appointment within
           fifteen days, the Bank acting reasonably shall be entitled to appoint
           such a person by notice to such Borrower or Borrowers. Nothing
           contained herein shall affect the right to serve process in any other
           manner permitted by law.

34.4       Each of the Borrowers irrevocably waives any objection which it might
           now or hereafter have to the courts referred to in Clause 34.2 being
           nominated as the forum to hear and determine any suit, action or
           proceeding, and to settle any disputes, which may arise out of or in
           connection with this Agreement and agrees not to claim that any such
           court is not a convenient or appropriate forum.

34.5       The submission to the jurisdiction of the courts referred to in
           Clause 34.2 shall not (and shall not be construed so as to) limit the
           right of the Bank to take proceedings against any of the Borrowers in
           any other court of competent jurisdiction nor shall the taking of
           proceedings in any one or more jurisdictions preclude the taking of
           proceedings in any other jurisdiction (whether concurrently or not)
           if and to the extent permitted by applicable law.

<PAGE>   13

         5.7.1    any Borrower may utilise the Acceptance Credit Facility if the
                  Bank receives, not later than 10.00 a.m. on the proposed
                  Utilisation Date a duly completed Request, substantially in
                  the form of Schedule 3 and signed by an Authorised Signatory
                  of such Borrower; and

         5.7.2    any Borrower may utilise the Acceptance Credit Facility by
                  notifying the Bank by telephone not later than 10.00 a.m. on
                  the proposed Utilisation Date provided that a notice given by
                  telephone shall be confirmed in writing by the delivery by
                  such Borrower to the Bank of a duly completed Request to be
                  actually received by the Bank not later than the close of
                  business in London on the day on which such telephone notice
                  is, or is deemed to have been, given.

         COMPLETION OF REQUESTS

5.8      When giving a notice of Utilisation by telephone and when completing
         the Request, the relevant Borrower must ensure that:

         5.8.1    the Utilisation Date is a Business Day;

         5.8.2    the Requested Amount is a minimum of Pound Sterling 1,000,000
                  and an integral multiple of Pound Sterling 100,000 or such
                  other amounts as the Bank and such Borrower may agree;

         5.8.3    only one Term is specified which:

                  (a)  does not overrun the Final Maturity Date; and

                  (b)  is a period of 7 to 183 days; and

         5.8.4    the payment instructions comply with Clause 9 (Payments).

         ACCEPTANCE OF BILLS

5.9      Unless the Bank notifies the relevant Borrower by 11.00 a.m. on the
         proposed Utilisation Date that the Bills referred to in the relevant
         telephone notice of Utilisation or Request will not be accepted by the
         Bank, the Bank shall accept such Bills on the relevant Utilisation Date
         provided they are completed in accordance with Clauses 5.11 and 5.12
         (Holding and Completion of Bills).

5.10     The Bank shall, as soon as is practicable but not later than 12.30 p.m.
         on the Utilisation Date notify the relevant Borrower of the applicable
         EBDR in relation to the Bills accepted or to be accepted in accordance
         with Clause 5.9.

         HOLDING AND COMPLETION OF BILLS

5.11     The relevant Borrower shall ensure that the Bank has a sufficient stock
         of Bills, before giving a telephone notice of Utilisation or delivering
         any Request for a Utilisation comprising Bills.



                                      -13-
<PAGE>   14

5.12     Each Bill shall:

         5.12.1   be drawn by the relevant Borrower in its own favour and
                  endorsed by it in blank;

         5.12.2   be undated;

         5.12.3   have the Maturity Date and the face amount left blank; and

         5.12.4   be claused in a manner which complies with the Bank of
                  England's requirements for Eligible Bills at that time.

         DISCOUNTING OF BILLS

5.13     The Bank may arrange for a Bill accepted by it to be discounted on its
         behalf in the London discount market or elsewhere or discount the Bill
         itself.

         INFORMATION RELATING TO BILLS

5.14     The relevant Borrower shall, promptly on request, supply to the Bank
         any information relating to any Bill (including the underlying trade
         transaction for that Bill) as the Bank may reasonably require or which
         may be required by the Bank of England or any other fiscal or monetary
         authority in the UK.

         ELIGIBLE BILLS

5.15     The relevant Borrower shall ensure that each Bill drawn by it and
         accepted by the Bank is, assuming that the Bank is a bank whose
         acceptances are then being treated as eligible acceptances by the Bank
         of England, eligible for re-discounting at the Bank of England.

         PAYMENT OF PROCEEDS

5.16     Subject to the terms of this Agreement, the Bank shall pay to the
         relevant Borrower on the relevant Utilisation Date an amount equal to:

         5.16.1   the amount which the Bank receives or would receive as the
                  proceeds of discounting if it had discounted the Bills
                  accepted by it hereunder at the applicable EBDR; less

         5.16.2   acceptance commission calculated at the applicable Acceptance
                  Commission Rate on the aggregate principal amount of those
                  Bills.

         NON-ACCEPTANCE OF BILLS

5.17     If the Bank gives the relevant Borrower notice under Clause 5.9 that
         the Bills referred to in the relevant telephone notice of Utilisation
         or Request will not be accepted by the Bank then, unless such Borrower,
         by notice to the Bank by 12.00 p.m. on the relevant Utilisation Date
         elects for the telephone notice of Utilisation or Request to be
         cancelled, without penalty, the said notice or Request shall be deemed
         to have been a request for an Advance of an amount equal to the
         Requested Amount and for a Term equal to the Term specified



                                      -14-
<PAGE>   15

         in the telephone notice or Request (or if the Bank does not agree to
         that Term then for a Term of 3 months) to be made available to such
         Borrower on such Utilisation Date.

         STANDARD OF CARE

5.18     In holding and dealing with Bills delivered to it under this Clause,
         the Bank shall use the same standard of care as it uses in holding and
         dealing with its own notes, bills or certificates of deposit and shall
         indemnify the relevant Borrower for any failure so to do. If the
         Commitment has been reduced to zero the Bank shall forthwith destroy
         all uncompleted Bills held by it and shall provide to the Company a
         certificate of destruction in respect thereof.

6.       CANCELLATION

         AUTOMATIC CANCELLATION OF THE COMMITMENT

6.1      The Commitment shall be automatically cancelled at close of business on
         the Final Maturity Date.

         VOLUNTARY CANCELLATION

6.2      The Company may, without penalty and by giving not less than 15 days'
         prior notice to the Bank, cancel the Commitment in whole or in part.

6.3      A notice of cancellation will be irrevocable and shall specify:

         6.3.1    the date on which the cancellation is to become effective; and

         6.3.2    the amount of the Commitment to be cancelled.

6.4      Any cancellation may only take effect in respect of the unutilised
         portion of the Commitment as at the date the notice is to be effective.

         NO REINSTATEMENT

6.5      No amount of the Commitment cancelled under this Agreement may
         subsequently be reinstated.

7.       INTEREST

         INTEREST RATE

7.1      The rate of interest on each Advance for its Term is the rate per annum
         determined by the Bank to be the aggregate of the applicable:

         7.1.1    Margin,



                                      -15-
<PAGE>   16

         7.1.2    LIBOR; and

         7.1.3    Mandatory Costs.

         DUE DATES

7.2      Except as otherwise provided in this Agreement, accrued interest on
         each Advance is payable on its Maturity Date and also, in the case of
         an Advance with a term longer than six months, on the date falling six
         months after its Utilisation Date.

         DEFAULT INTEREST

7.3      If any Borrower fails to pay any amount payable by it under this
         Agreement, it shall, on demand by the Bank from time to time, pay
         interest on the overdue amount from the due date up to the date of
         actual payment, after as well as before judgment, at a rate (the
         "default rate") determined by the Bank to be one (1) per cent. per
         annum above the higher of:

         7.3.1    the rate on the overdue amount under Clause 7.1 (Interest
                  rate) immediately before the due date (but only if the overdue
                  amount is an Advance (or part thereof) and only for the period
                  up to and including the Maturity Date of that Advance); and

         7.3.2    the rate which would have been payable if the overdue amount
                  had, during the period of non-payment, constituted an Advance
                  in the currency of the overdue amount for such successive
                  Terms of such duration (not exceeding three months) as the
                  Bank may reasonably determine (each a "Designated Term").

7.4      The default rate will be determined on the first day of, or two
         Business Days before the first day of, the relevant Designated Term, as
         appropriate.

7.5      If the Bank determines that deposits in the currency of the overdue
         amount are not at the relevant time being made available by leading
         banks in the London Interbank Market, the default rate will be
         determined by reference to the cost of funds to the Bank from whatever
         sources it may reasonably select.

7.6      Default interest shall be compounded at the end of each Designated Term
         until it is paid.

         NOTIFICATION OF RATES OF INTEREST

7.7      The Bank shall promptly notify the relevant Borrower of the
         determination of any applicable rate of interest under this Agreement.

8.       REPAYMENT AND PREPAYMENT

         PAYMENT OF BILLS

8.1      Each Borrower shall pay to the Bank an amount equal to the principal
         amount of each of its Bills accepted by the Bank on the Maturity Date
         for each such Bill.

         REPAYMENT OF ADVANCES

8.2      Each Borrower shall repay each Advance made to it in full on its
         Maturity Date to the Bank. If an Advance (the "New Advance") is to be
         made to a Borrower on the day on which another Advance (the "Maturing
         Advance") in the same currency is due to be repaid by such Borrower
         then, subject to the terms of this Agreement and so long as the
         conditions referred to in Clause 4.2 shall have been satisfied in
         relation to the New Advance:

         8.2.1    the Maturing Advance shall be deemed to have been repaid on
                  its Maturity Date either in whole (if the New Advance is equal
                  to or greater than the Maturing Advance) or in part (if the
                  New Advance is less than the Maturing Advance); and

         8.2.2    to the extent that a Maturing Advance is so deemed to have
                  been repaid, the principal amount of the New Advance to be
                  made on such a date shall be deemed to have been credited to
                  the account of such Borrower by the Bank in accordance with
                  the terms of this Agreement and, as the case may be:

                  (a)  the Bank shall only be obliged to make available to such
                       Borrower pursuant to Clause 5.6 a principal amount equal
                       to the amount (if any) by which the New Advance exceeds
                       the Maturing Advance; or

                  (b)  such Borrower shall only be obliged to pay to the Bank
                       pursuant to this Clause 8.2 a principal amount equal to
                       the amount by which the Maturing Advance exceeds the New
                       Advance.

8.3      On the Final Maturity Date, all outstanding Utilisations and other sums
         (if any) then owing under this Agreement shall in any event be repaid
         or paid in full.

         PREPAYMENT OF BILLS

8.4      Any Borrower may, by giving not less than 15 days' prior notice to the
         Bank, prematurely comply with its obligations under Clause 8.1 (Payment
         of Bills).

8.5      If, under the terms of this Agreement, including without limitation
         this Clause 8 and Clauses 14.1.2 and 15.2.2, a Borrower prematurely
         complies with its obligations under Clause 8.1 (Payment of Bills) in
         respect of any Bill, then the amount payable by such Borrower shall be
         the principal amount equal to the Bill discounted on the basis of such
         normal commercial rates prevailing at the time of payment for Sterling
         deposits of an amount equal to the amount so paid for the period from
         the time of payment to the Maturity Date of the Bill as the Bank may
         reasonably determine. If and to the extent that


                                      -17-
<PAGE>   18


         a Borrower pays more than it is obliged to pay under this Clause then
         the Bank shall pay to such Borrower an amount equal to such
         over-payment by no later than the Maturity Date of the relevant Bill.

         PREPAYMENT OF ADVANCES

8.6      Any Borrower may, without penalty and on giving not less than 15 days'
         prior notice to the Bank, prepay all or any part of an Advance, but if
         in part, in a minimum amount of Pound Sterling 1,000,000 and an
         integral multiple of Pound Sterling 100,000 (or the comparable amount
         in any Optional Currency).

8.7      Any notice by a Borrower of prepayment under this Agreement is
         irrevocable.

8.8      Should any person or group of persons, acting either individually or in
         concert (as defined in the City Code on Take Overs and Mergers
         effective as at the date of this Agreement) otherwise than with the
         consent of the Bank acquire control of the Company (and for the purpose
         of this Clause a single person or group of persons shall have acquired
         control if it or they own or hold more than 50% (fifty per cent.) of
         the issued share capital of the Company having the right to attend and
         vote at general meetings of the Company or more than 50% (fifty per
         cent.) of such rights), then:

         8.8.1    the Company shall immediately upon becoming aware thereof
                  notify the Bank specifying the date of such acquisition and
                  the name of such person or persons acquiring control; and

         8.8.2    thereafter no Borrower shall be permitted to request a
                  Utilisation unless the terms of the acquisition of control of
                  the Company were approved by the Board of Directors of the
                  Company and the Maturity Date for any Utilisation requested
                  falls on a date not more than three months after the
                  expiration of the 30 day period referred to in Clause 8.9.

8.9      If the terms of the acquisition of control of the Company were approved
         by the Board of Directors of the Company, the Bank shall consult with
         the Company during the period of 30 days after receipt of the
         notification from the Company referred to in sub-Clause 8.8.1 and shall
         be entitled to give a notice of continuance of each Facility to the
         Company. Upon receipt of such notice of continuance, the right of the
         Borrowers to request a Utilisation without the limitation referred to
         in sub-Clause 8.8.2 shall be reinstated.

8.10     If the terms of the acquisition of control of the Company were approved
         by the Board of Directors of the Company but, at the end of the period
         of 30 days referred to in Clause 8.9 above, the Company has not
         received a notice of continuance then:

         8.10.1   the Acceptance Credit Facility and the Loan Facility shall be
                  cancelled;

         8.10.2   any outstanding Utilisations with Maturity Dates falling later
                  than three months after the end of such period shall be
                  prepaid on the date falling three months after the end of such
                  period, together with accrued interest thereon up to the date
                  of payment and all other amounts payable to the Bank
                  hereunder; and



                                      -18-
<PAGE>   19

         8.10.3   any outstanding Utilisations with Maturity Dates falling not
                  later than three months after the end of such period shall be
                  repaid on their respective Maturity Dates.

8.11     If the terms of the acquisition of control of the Company were not
         approved by the Board of Directors of the Company, then unless the Bank
         shall have confirmed within 2 days of receipt of the notice referred to
         in sub-Clause 8.8.1 that each Facility shall be continued, each
         Facility shall be cancelled and any outstanding Utilisations shall be
         repayable on demand by the Bank together with accrued interest thereon
         up to the date of payment and all other amounts payable to the Bank
         hereunder.

8.12     Any prepayment of an Advance under this Agreement shall be made
         together with accrued interest on the amount prepaid together with any
         amount payable to the Bank pursuant to Clause 22.3

8.13     No Advance may be prepaid otherwise than in accordance with the express
         terms of this Agreement.

         Participating Member State by crediting an account of the creditor, can
         be paid by the debtor either in the euro unit or in that national
         currency unit, a Party shall be entitled to pay that amount either in

         PARTIAL PAYMENTS

9.11     If the Bank receives a payment insufficient to discharge all the
         amounts then due and payable by any Borrower under this Agreement, the
         Bank shall apply that payment towards the obligations of such Borrower
         under this Agreement in the following order:

         9.11.1   firstly, in or towards payment of any unpaid costs and
                  expenses of the Bank under this Agreement;

         9.11.2   secondly, in or towards payment of any accrued fees due but
                  unpaid under Clause 19.2 (Commitment Fee);

         9.11.3   thirdly, in or towards payment of any accrued interest due but
                  unpaid under this Agreement;

         9.11.4   fourthly, in or towards payment of any principal due but
                  unpaid under this Agreement, and

         9.11.5   fifthly, in or towards payment of any other sum due but unpaid
                  under this Agreement.

9.12     The Bank may vary the order set out in sub-Clauses 9.11.1 to 9.11.5
         above.

9.13     Clauses 9.11 and 9.12 above shall override any appropriation made by
         any Borrower.

10.      OPTIONAL CURRENCIES

         SELECTION

10.1     No Borrower may request an Advance denominated in an Optional Currency
         unless the Bank has confirmed to such Borrower that the Optional
         Currency is readily available and freely transferable in the London
         foreign exchange market.

         CHANGE OF CURRENCY

10.2     If, on the Rate Fixing Day of an Advance to be denominated in an
         Optional Currency, the Bank determines that:

         10.2.1   it is impracticable for reasons beyond its control for the
                  Bank to fund the Advance for its Term in that Optional
                  Currency in the ordinary course of business in the London
                  Interbank Market; or

         10.2.2   the use of the proposed Optional Currency might contravene any
                  law or regulation,

                  then:

         10.2.3   the Bank shall promptly and in any event before 10.30 a.m. on
                  that Rate Fixing Day notify the relevant Borrower;

         10.2.4   if the Bank receives notice from the relevant Borrower by
                  11.30 a.m. on that Rate Fixing Day to that effect, the Advance
                  will not be made; and

         10.2.5   if the Bank does not receive any notice under sub-Clause
                  10.2.4 above, the Advance will be denominated instead in
                  Sterling in an amount equal to its Original Sterling Amount.

         NOTIFICATION OF RATES AND AMOUNTS

10.3     The Bank shall, on request, promptly notify the relevant Borrower of
         any applicable Bank's Spot Rate of Exchange or Original Sterling Amount
         promptly after it has been ascertained.

10.4     If an Advance which has been drawn in an Optional Currency is
         reborrowed in the same Optional Currency immediately following its
         repayment, then the Original Sterling Amount of such new Advance
         denominated in such Optional Currency shall be recalculated for the new
         Term in accordance with the terms and conditions of this Agreement and
         if on the




                                      -21-
<PAGE>   22

         relevant Utilisation Date the aggregate Original Sterling Amount of all
         Utilisations outstanding on such date exceeds the Commitment, then any
         excess shall be repaid to the Bank by the relevant Borrower upon the
         Bank's first written demand.

11.      TAXES

         GROSS-UP

11.1     All payments by each of the Borrowers under this Agreement shall be
         made without any deductions and free and clear of and without deduction
         for or on account of any Relevant Taxes except to the extent that any
         Borrower is required by law to make payment subject to any such taxes.
         If any Relevant Tax or amounts in respect of any Relevant Tax must be
         deducted from any amounts payable or paid by any Borrower hereunder,
         such Borrower shall pay such additional amounts as may be necessary to
         ensure that the Bank receives a net amount equal to the full amount
         which it would have received had payment not been made subject to tax.

         "Relevant Tax" in relation to any payment which falls to be made
         hereunder means any present or future taxes of any nature now or
         hereafter imposed by the laws of (i) the United Kingdom, (ii) any other
         jurisdiction from which, or through which, such payment is made or to
         the taxation laws of which the relevant Borrower is at the time of such
         payment subject, (iii) any political sub-division of the United Kingdom
         or any such other jurisdiction or (iv) any federation or association of
         states of which the United Kingdom or any such other jurisdiction is,
         at the time of such payment, a member.

         TAX RECEIPTS

11.2     All Relevant Taxes required by law to be deducted or withheld by any
         Borrower from any amount paid or payable under this Agreement shall be
         paid by such Borrower when due (unless the obligation to pay is being
         disputed in good faith) and such Borrower shall, within 30 days of the
         payment being made, deliver to the Bank evidence satisfactory to the
         Bank (including all relevant tax receipts) that the payment has been
         duly remitted to the appropriate authority.

         TAX CREDITS

11.3     If any Borrower pays any additional amount (a "Tax Payment") under
         Clause 11.1 and the Bank effectively obtains a refund of tax, or a
         relief or credit against tax by reason of that Tax Payment (a "Tax
         Credit"), and the Bank is able to identify the Tax Credit as being
         attributable to the Tax Payment, then the Bank shall reimburse to the
         relevant Borrower such amount as the Bank reasonably determines to be
         the proportion of the Tax Credit as will leave the Bank (after that
         reimbursement) in no better or worse position that it would have been
         if the Tax Payment had not been required. Nothing in this Clause
         interferes with the right of the Bank to arrange its tax affairs in
         whatever manner it thinks fit and, without prejudice to the foregoing,
         the Bank is under no obligation to claim a Tax Credit, or to claim a
         Tax Credit in priority to any other claim, relief, credit or deduction




                                      -22-
<PAGE>   23

         available to it. The Bank is not obliged to disclose any information
         regarding its tax affairs or computations to any Borrower.

         QUALIFYING BANK

11.4     If, otherwise than as a result of the introduction of, change in, or
         change in the interpretation, administration or application of, any law
         or regulation or any practice or concession of the Inland Revenue after
         the Signing Date, the Bank ceases to be a Qualifying Bank no Borrower
         shall be liable to pay to the Bank under Clause 11.1 (Gross-up) any
         amount in respect of taxes levied or imposed by the UK or any taxing
         authority thereof or therein in excess of the amount it would have been
         obliged to pay if the Bank had been or had not ceased to be a
         Qualifying Bank.

12.      MARKET DISRUPTION

         MARKET DISRUPTION - ADVANCES

12.1     If, in relation to any proposed Utilisation comprising Advances:

         12.1.1   the Bank is unable to obtain from leading banks a rate for the
                  purposes of determining the applicable LIBOR or the Bank
                  otherwise determines that adequate and fair means do not exist
                  for ascertaining the applicable LIBOR; or

         12.1.2   in the opinion of the Bank:

                  (a)  matching deposits may not be available to it in the
                       London Interbank Market in the ordinary course of
                       business to fund an Advance; or

                  (b)  the cost to it of matching deposits in the London
                       Interbank Market would be in excess of the relevant
                       LIBOR,

         the Bank shall notify the Company by 10.30 a.m. or as soon as is
         practicable thereafter on the Rate Fixing Day of the fact and that this
         Clause is in operation.

12.2     After any notification under Clause 12.1. above:

         12.2.1   subject to sub-Clause 12.2.3 below the relevant Advance shall
                  be made in Sterling in an amount equal to its Original
                  Sterling Amount (unless Sterling was the original currency of
                  the relevant Advance);

         12.2.2   subject to sub-Clause 12.2.3 below, no further notices of
                  Utilisation by telephone or Requests for Advances to be
                  denominated in the original currency of the affected Advance
                  may be delivered until the Bank notifies the Company that the
                  event specified in the notification no longer prevails;

         12.2.3   the relevant Borrower may, by notice to the Bank by 11.00 a.m.
                  (or, if later, within 30 minutes of receipt by the Company of
                  a notification under Clause 12.1)




                                      -23-
<PAGE>   24

                  on the Rate Fixing Day: (i) elect for the notice of
                  Utilisation by telephone or Request to be cancelled without
                  penalty; (ii) if the Advance was to be made in an Optional
                  Currency, elect for the Advance to be made in an Optional
                  Currency other than a currency affected by the event specified
                  in the notification or (iii) elect for the Advance to be made
                  in accordance with the Request notwithstanding the event
                  specified in the notification. If any Borrower requires an
                  affected Advance to be made in the original currency selected
                  for such Advance notwithstanding the event specified in the
                  notification then within five Business Days of receipt of the
                  notification, the Company and the Bank shall enter into
                  negotiations for a period of not more than 25 days with a view
                  to agreeing a substitute basis for determining the rate of
                  interest and/or funding applicable to the affected Advance and
                  any future Advances in the currency of the affected Advance
                  provided that if no substitute basis is agreed within that
                  period:

                  (a)  the Bank shall certify to the Company (such certificate
                       to be conclusive) the alternative interest rate
                       calculated in accordance with sub-Clause 12.2.4 below;

                  (b)  the certificate may make provision for different funding
                       periods and shall be retroactive to the beginning of the
                       then current Term; and

                  (c)  the certificate shall be binding on each relevant
                       Borrower unless the Company gives notice to the Bank
                       within five Business Days of the receipt of the
                       certificate that the certificate is not acceptable and
                       that each relevant Borrower shall prepay in full the
                       relevant Advances on a Business Day specified in the
                       notice, which shall be not less than five nor more than
                       thirty days after the date of the Bank's certificate to
                       the Company; and

         12.2.4   for the purposes of sub-Clause 12.2.3(a) above the rate of
                  interest on each Advance shall be the rate certified by the
                  Bank as the rate per annum determined by the Bank to be the
                  aggregate of:

                       (i)      the Margin;

                       (ii)     the rate notified by the Bank, on or before the
                                last day of its Term, as being the cost to the
                                Bank of funding the Advance from such other
                                sources as it may reasonably select; and

                       (iii)    the applicable Mandatory Cost if any.

12.3     During the period when any substitute basis is in force in relation to
         a particular currency, the Bank shall periodically determine whether
         the circumstances referred to in Clause 12.1 above still apply and, if
         they do not, shall forthwith give notice in writing to the Company of
         the date on which the substitute basis will cease to apply.

         MARKET DISRUPTION - BILLS

12.4     If, in relation to any Bills:

         12.4.1   the Bank, acting reasonably, determines that adequate and fair
                  means do not exist for determining the applicable EBDR; or

         12.4.2   the Bank, acting reasonably, determines that the Bills do not
                  comply with the then current Bank of England regulations for
                  Sterling bankers' acceptances

         the Bank shall notify the Company by 12.00 p.m. on the Utilisation Date
         of the fact and that this Clause is in operation.

12.5     After any notification under Clause 12.4 above:

         12.5.1   those Bills shall not be accepted;

         12.5.2   in the case of Clause 12.4.1, no further Requests for Bills
                  may be delivered until the Bank notifies the Company that it
                  is once again able to determine EBDR; and

         12.5.3   unless the relevant Borrower, by notice to the Bank by 12.30
                  p.m. on the relevant Utilisation Date, elects for the
                  telephone notice of Utilisation or Request for Bills to be
                  cancelled without penalty, the said notice or Request shall be
                  deemed to have been a request for an Advance of an amount
                  equal to the Requested Amount and for a Term equal to the Term
                  specified in the telephone notice or Request (or if the Bank
                  does not agree to that Term, then for a Term of 3 months) to
                  be made available to such Borrower on such Utilisation Date.

13.      INCREASED COSTS

         INCREASED COSTS - SERVICE OF DEMAND

13.1     If the result of any introduction of or change in any law or regulation
         after the Signing Date, or of any change in the application or
         interpretation of any such changed law or regulation or compliance by
         the Bank with any such changed law or regulation after the Signing Date
         (including, without limitation, any law or regulation relating to
         taxation, any reserve, special deposit, cash ratio, liquidity or
         capital adequacy requirement or any form of banking or monetary control
         but excluding (i) changes arising from the implementation by any
         authority having jurisdiction over the Bank or its holding company of
         the matters set out in the statement prepared by the Basle Committee on
         Banking Regulations and Supervisory Practices dated July 1988 and
         entitled "International Convergence of Capital Measurement and Capital
         Standards" (as amended in November 1991) and (ii) changes arising from
         the implementation in whole or in part by any authority having
         jurisdiction over the Bank or its holding company of the proposals
         contained in the matters set out in the EC Directive 93/6/EEC of 15
         March 1993 on the capital adequacy of investment firms and credit
         institutions) is that the Bank incurs an increased cost, then the Bank
         will promptly notify the Company of the relevant event and the Company
         shall on demand pay


                                      -25-
<PAGE>   26

         to the Bank such amount as the Bank certifies in the demand will
         compensate it for the applicable increased cost.

13.2     In this Clause 13 "increased cost" means:

         13.2.1   an additional cost incurred by the Bank as a result of it
                  having entered into, or performing, maintaining or funding its
                  obligations under, this Agreement; or

         13.2.2   that portion of an additional cost incurred by the Bank in
                  making, funding or maintaining all or any advances comprised
                  in a class of advances formed by or including the Advances
                  made or to be made by it under this Agreement as is
                  attributable to it making, funding, or maintaining such
                  advances; or

         13.2.3   a reduction in any amount payable to the Bank or the effective
                  return to the Bank under this Agreement or on its capital; or

         13.2.4   any payment made or interest or other return on or calculated
                  by reference to any amount received or receivable by the Bank
                  under this Agreement which is forgone.

13.3     When calculating an increased cost, the Bank may allocate or spread
         costs, liabilities and losses to or across its liabilities or assets,
         or any class of liabilities or assets, and on such basis, as it
         reasonably considers appropriate.

         INCREASED COSTS - EXCEPTIONS

13.4     An increased cost does not include any increased cost:

         13.4.1   compensated for by the payment of the Mandatory Cost;

         13.4.2   compensated for by the operation of Clause 11 (Taxes);

         13.4.3   attributable to any change in the rate of tax on the overall
                  net income of the Bank (or the overall net income of a
                  division or branch of the Bank) imposed in the jurisdiction in
                  which its principal office or the relevant lending office for
                  the time being is situate;

         13.4.4   payable to an assignee or transferee of the Bank at the time
                  of an assignment, transfer or novation under Clause 25
                  (Changes to the Parties), but only to the extent that the
                  increased cost would not have been payable to the assigning,
                  transferring or novating Bank; or

         13.4.5   which is attributable to the introduction of the euro other
                  than an increased cost which is being incurred generally by
                  banks transacting euro business in the London interbank
                  market.

14.      ILLEGALITY

14.1     If it is or becomes unlawful for the Bank to give effect to any of its
         obligations as contemplated by this Agreement or to fund or maintain
         any Utilisation, then the Bank shall notify the Company accordingly and
         on the Maturity Date of each relevant Utilisation (or such earlier date
         as the relevant law or directive may require):-

         14.1.1   the relevant Borrower shall repay or prepay, as the case may
                  be, any Advances made to it by the Bank together with all
                  other amounts payable by it to the Bank under this Agreement;
                  and

         14.1.2   the Company's obligations under Clause 8.1 (Payment of Bills)
                  in respect of Bills accepted by the Bank shall immediately
                  become due for performance and the Company shall immediately
                  perform those obligations.

14.2     The Bank's Commitment shall be cancelled on the date of a notification
         under Clause 14.1 above.

15.      TAXES AND INCREASED COSTS - ADDITIONAL RIGHTS

         PREPAYMENT AND CANCELLATIONS

15.1     If any Borrower is required to pay any additional amounts to the Bank
         under Clause 11 (Taxes) or compensation under Clause 13 (Increased
         Costs), the Company may, whilst the circumstances giving rise to the
         requirement continue, serve a notice of prepayment and cancellation in
         relation to all or all affected Advances and Bills on the Bank.

15.2     On the tenth Business Day after the date of service of the notice:

         15.2.1   each Borrower shall prepay the relevant Advance or Advances
                  made to it by the Bank together with all other amounts in
                  relation to such Advance(s) payable by it to the Bank under
                  this Agreement; and

         15.2.2   each Borrower's obligations under Clause 8.1 (Payment of
                  Bills) in respect of Bills accepted by the Bank shall
                  immediately become due for performance and the relevant

         MITIGATION

15.4     If, in respect of the Bank, circumstances arise which would or would,
         with the giving of notice, result in:

         15.4.1   any additional amounts becoming payable under Clause 11
                  (Taxes); or

         15.4.3   any prepayment, payment or cancellation under Clause 14
                  (Illegality),

         then the Bank shall endeavour to take such steps as are reasonably open
         to it to mitigate or remove those circumstances (including seeking
         recovery for the account of the relevant Borrower where reasonably
         practicable and/or transferring its rights and obligations under this
         Agreement to another bank or financial institution acceptable to the
         Company).

15.5     Clause 15.4 above does not:

         15.5.1   prejudice the obligations of any Borrower under this Agreement
                  (including, without limitation, under the Clauses referred to
                  in Clause 15.4 above); or

         15.5.2   require the Bank to take any action which, in its opinion,
                  might be in any way prejudicial to it or conflict with its

         (inclusive) occurs in relation to a Material Subsidiary which is not a
         Borrower it will only be an Event of Default if the event is, in the
         reasonable opinion of the Bank, reasonably likely to affect materially
         and adversely the Company's ability to perform its obligations under
         this Agreement.

         NON-PAYMENT

18.2     Any Borrower defaults in payment on the due date of any amount payable

         relevant Borrower of the default.

         BREACH OF OTHER OBLIGATIONS

18.3     Any Borrower fails to observe or perform any other obligation on its
         part contained in this Agreement (other than those which, in the

         a breach capable of being remedied) fails to remedy the breach within
         fourteen Business Days after the date on which the Company and the
         relevant Borrower receive notice of the breach from the Bank.

         Subsidiary:

                  grace period); or

         18.5.2   become prematurely due and payable or are placed on demand as
                  a result of an event of default (howsoever described) under

         fall due.

         CURRENCY INDEMNITY

22.1     If the Bank receives an amount in respect of any Borrower's liability
         under this Agreement or if such liability is converted into a claim,
         proof, judgement or order in a currency other than the currency (the
         "CONTRACTUAL CURRENCY") in which the amount is expressed to be payable
         under this Agreement:

         22.1.1   the relevant Borrower will indemnify the Bank as an
                  independent obligation against any loss arising out of or as a
                  result of such conversion;

         22.1.2   if the amount received by the Bank, when converted into the
                  contractual currency, at the Bank's Spot Rate of Exchange is
                  less than the amount owed in the contractual currency, the
                  relevant Borrower shall, forthwith on demand, pay to the Bank
                  an amount in the contractual currency equal to the deficit;

         22.1.4   if the amount received by the Bank when converted into the
                  contractual currency, at the Bank's Spot Rate of Exchange is
                  more than the amount owed in the contractual currency the Bank
                  shall promptly account to the relevant Borrower an amount in
                  the contractual currency equal to the excess.

22.2     Each Borrower waives any right it may have in any jurisdiction to pay
         any amount under this Agreement in a currency other than that in which
         it is expressed to be payable.

         OTHER INDEMNITIES

         22.3.3   any payment of principal or an overdue amount being received
                  from any source otherwise than on its Maturity Date and, for
                  the purposes of this sub-Clause 22.3.3, the Maturity Date of
                  an overdue amount is the last day of each Designated Term (as
                  defined in Clause 7.3 (Default interest)); or

         22.3.4   (other than by reason of negligence or default by the Bank) a
                  Utilisation not being effected after the relevant Borrower has
                  delivered a notice of Utilisation by telephone or a Request
                  (save where such notice or Request is expressly permitted to
                  be cancelled hereunder).

         The Company's liability in each case includes, without limitation, any
         loss of margin or other loss or expense on account of funds borrowed,
         contracted for or utilised to fund any amount payable under this

                  liable to pay to the Bank under or pursuant to this Agreement
                  and which shall not have been paid at the time such demand is
                  made; and

         22.4.2   agrees as a primary obligation to indemnity the Bank from time
                  to time on demand by the Bank from and against any loss
                  incurred by the Bank as a result of any of the obligations of
                  each Borrower under or pursuant to this Agreement becoming
                  void, voidable, unenforceable or ineffective as against each
                  such Borrower for any reason whatsoever, whether or not known
                  to the Bank, the

                  amount of such loss being the amount which the person or
                  persons suffering it would otherwise have been entitled to
                  recover from any Borrower.

         "Obligations") shall be in addition to and independent of every other
         security which the Bank may at any time hold in respect of the
         obligations of the Borrowers under this Agreement.

         notwithstanding any settlement of account or other matter or thing

         or any of the obligations of the Borrowers under this Agreement and
         shall continue in full force and effect until final payment in full of
         all amounts owing by the Borrowers thereunder and total satisfaction of
         all actual and contingent obligations thereunder.

22.7     Neither the Obligations nor the rights, powers and remedies conferred
         in respect of the Company in relation thereto upon the Bank by this

                  of any Borrower or any other person or any change in its
                  status, function, control or ownership;

         22.7.2   any of the obligations of any Borrower or any other person
                  hereunder or under any other security taken in respect of any
                  of its obligations hereunder being or becoming illegal,
                  invalid, unenforceable or ineffective in any respect;

         22.7.3   time or other indulgence being granted or agreed to be granted
                  to any Borrower in respect of its obligations hereunder or

                  security taken in respect of any Borrower's obligations
                  hereunder; or

         22.7.7   any other act, event or omission including, (without
                  limitation, any amendment to this Agreement) which, but for
                  this Clause 22.7 might operate to discharge, impair or
                  otherwise affect any of the obligations of the Borrowers or
                  the Company herein contained or any of the rights, powers or
                  remedies conferred upon the Bank by this Agreement or by law.

22.8     Any settlement or discharge between the Company and the Bank shall be
         conditional upon no security or payment to the Bank by any Borrower or
         any other person being avoided or




                                      -38-

         bankruptcy, insolvency, liquidation or similar laws of general
         application for the time being in force and, if any such security or
         payment is so avoided or reduced, the Bank shall be entitled to recover
         the value or amount of such security or payment from the Company
         subsequently as if such settlement or discharge had not occurred.

22.9     The Bank shall not be obliged before exercising any of the rights,

         any Borrower hereunder or any Borrower is under any actual or
         contingent obligations hereunder, it shall not exercise any rights

         22.10.1  to be indemnified by any other Borrower; and/or

         22.10.2  to claim any contribution from any other Borrower; and/or;

31.      DESIGNATION OF ACCEDING AND SECEDING BORROWERS

31.1     The Company may request that any of its Subsidiaries incorporated in
         England and Wales and, with the prior written consent of the Bank (such
         consent not to be unreasonably withheld or delayed) any other
         Subsidiary of the Company becomes an Acceding Borrower by delivering or
         procuring the delivery to the Bank a Borrower's Accession Notice duly
         executed by the Company and the relevant Subsidiary provided that if
         such Subsidiary is not resident in the United Kingdom for tax purposes
         the Company and the Bank agree to make such amendments to this
         Agreement as may be reasonably required at the time in order to allow
         such Subsidiary to pay interest to the Bank without deduction or
         withholding of any Relevant Tax and to provide such Subsidiary with
         equivalent rights, mutatis mutandis, to those contained in Clause 11.4
         (Qualifying Bank).

31.2     Upon delivery of a Borrower's Accession Notice, the relevant Subsidiary
         shall become an Acceding Borrower and shall, subject to the terms and
         conditions of this Agreement acquire all the rights and assume all the
         obligations of a Borrower hereunder provided that the Bank has
         confirmed to the Company that it has received, in form and substance
         satisfactory to it, all the documents set out in Part II of Schedule 1.

31.3     The Company undertakes that it shall procure that each Acceding
         Borrower shall provide the Bank with each of the documents listed in
         Part II of Schedule 1.

31.4     If at any time any Borrower (other than the Company) has no actual or
         contingent obligations under this Agreement, the Company may deliver a
         Borrower's Cessation Notice to the Bank in which event such Borrower
         shall forthwith cease to be a Borrower upon receipt by the Bank of such
         notice.

32.      CHANGE OF CURRENCY

32.1     If more than one currency or currency unit are at the same time

         that country, then:

         32.1.1   any reference in this Agreement to, and any obligations
                  arising under this Agreement in, the currency of that country
                  shall be translated into, or paid in, the currency unit of
                  that country designated by the Bank acting reasonably and in
                  consultation with the Company; and

         32.1.2   any translation from one currency unit to another shall be at
                  the official rate of exchange recognised by the relevant

         proceeding, and to settle any disputes, which may arise out of or in
         connection with this Agreement and agrees not to claim that any such
         court is not a convenient or appropriate forum.

34.5     The submission to the jurisdiction of the courts referred to in Clause
         34.2 shall not (and shall not be construed so as to) limit the right of
         the Bank to take proceedings against any of the Borrowers in any other
         court of competent jurisdiction nor shall the taking of

         proceedings in any one or more jurisdictions preclude the taking of

2.         NATURE OF THE FACILITY

           FACILITY

2.1        The Bank grants to the Borrowers a revolving multi-currency advances
           facility under which the Bank shall, during the Availability Period
           and when requested by a Borrower, make to such Borrower Advances upon
           and subject to the terms of this Agreement.

           OVERALL FACILITY LIMIT

2.2        The aggregate Original Sterling Amount of all outstanding Advances
           shall not at any time exceed the Commitment at that time.

           NUMBER OF REQUESTS AND UTILISATIONS

2.3        Any number of Requests may be delivered on the same day and/or
           specifying the same Utilisation Date, whether or not the currencies
           and Terms requested are similar.

3.         PURPOSE

3.1        Each Borrower shall apply each Utilisation made to it towards the
           general corporate purposes of the Group.

3.2        Without affecting the obligations of any of the Borrowers in any way,
           the Bank shall not be bound to monitor or verify the application of
           the proceeds of any Utilisation.

4.         CONDITIONS PRECEDENT

           DOCUMENTARY CONDITIONS PRECEDENT

4.1        The obligations of the Bank to the Borrowers under this Agreement are
           subject to the condition precedent that the Bank has notified the
           Company that it has received, not later than 3 Business Days prior to
           the first Utilisation Date, all of the documents set out in Part I of
           Schedule 1 in form and substance satisfactory to the Bank.

           FURTHER CONDITIONS PRECEDENT

4.2        The obligation of the Bank to make each Utilisation is subject to the
           further conditions precedent that:

                                      -9-
<PAGE>   10

          4.2.1      on both the date of the Request and the Utilisation Date
                     for that Utilisation:

                     (a)    the representations and warranties in Clause 16
                            (Representations and Warranties) to be repeated
                            on those dates are correct and will be correct
                            immediately after the Utilisation; and

                     (b)    no Default is outstanding or might result from the
                            Utilisation; and

          4.2.2      the Utilisation would not cause Clause 2.2 (Overall
                     facility limit) to be contravened.

           THE LOAN FACILITY

           substantially in the form of Schedule 3 and signed by an Authorised
           Signatory of the relevant Borrower.

5.2        Any Borrower may utilise the Loan Facility by notifying the Bank by
           telephone not later than 10.00 a.m. on the Rate Fixing Day provided

           delivery by the relevant Borrower to the Bank of a duly completed
           Request to be actually received by the Bank not later than the close
           of business in London on the day on which such telephone notice is,

                              the amounts agreed between the relevant Borrower
                              and the Bank before the telephone notice of
                              Utilisation or delivery of that Request; or

                                      -10-
<PAGE>   11

                      (d)     such other amounts as the Bank and the relevant

           "OPTIONAL DURATION" means any other period not exceeding 12 months.

           if the selection of a Term of an optional duration becomes
           ineffective in accordance with Clause 5.5.2.

           the Term for the proposed Utilisation shall be the alternative period
           specified in the telephone notice of Utilisation or the relevant

7.         INTEREST

           INTEREST RATE

7.1        The rate of interest on each Advance for its Term is the rate per
           annum determined by the Bank to be the aggregate of the applicable:

           7.1.1      Margin,

           7.1.2      LIBOR; and

           7.1.3      Mandatory Costs.

           DUE DATES

7.2        Except as otherwise provided in this Agreement, accrued interest on
           each Advance is payable on its Maturity Date and also, in the case of
           an Advance with a term longer than six months, on the date falling
           six months after its Utilisation Date.

           DEFAULT INTEREST

7.3        If any Borrower fails to pay any amount payable by it under this
           Agreement, it shall, on demand by the Bank from time to time, pay
           interest on the overdue amount from the due date up to the date of
           actual payment, after as well as before judgment, at a rate (the
           "DEFAULT RATE") determined by the Bank to be one (1) per cent. per
           annum above the higher of:

           7.3.1       the rate on the overdue amount under Clause 7.1 (Interest
                       rate) immediately before the due date (but only if the
                       overdue amount is an Advance (or part thereof) and only
                       for the period up to and including the Maturity Date of
                       that Advance); and

                                     -12-
<PAGE>   13

           7.3.2     the rate which would have been payable if the overdue
                     amount had, during the period of non-payment, constituted
                     an Advance in the currency of the overdue amount for such
                     successive Terms of such duration (not exceeding three
                     months) as the Bank may reasonably determine (each a
                     "DESIGNATED TERM").

7.4        The default rate will be determined on the first day of, or two
           Business Days before the first day of, the relevant Designated Term,
           as appropriate.

7.5        If the Bank determines that deposits in the currency of the overdue
           amount are not at the relevant time being made available by leading
           banks in the London Interbank Market, the default rate will be
           determined by reference to the cost of funds to the Bank from
           whatever sources it may reasonably select.

7.6        Default interest shall be compounded at the end of each Designated
           Term until it is paid.

           NOTIFICATION OF RATES OF INTEREST

7.7        The Bank shall promptly notify the relevant Borrower of the
           determination of any applicable rate of interest under this
           Agreement.

8.         REPAYMENT AND PREPAYMENT

           REPAYMENT OF ADVANCES

8.1        Each Borrower shall repay each Advance made to it in full on its
           Maturity Date to the Bank. If an Advance (the "NEW ADVANCE") is to be
           made to a Borrower on the day on which another Advance (the "MATURING
           ADVANCE") in the same currency is due to be repaid by such Borrower
           then, subject to the terms of this Agreement and so long as the
           conditions referred to in Clause 4.2 shall have been satisfied in
           relation to the New Advance:

           8.1.1     the Maturing Advance shall be deemed to have been repaid on
                     its Maturity Date either in whole (if the New Advance is
                     equal to or greater than the Maturing Advance) or in part
                     (if the New Advance is less than the Maturing Advance); and

           8.1.2     to the extent that a Maturing Advance is so deemed to have
                     been repaid, the principal amount of the New Advance to be
                     made on such a date shall be deemed to have been credited
                     to the account of such Borrower by the Bank in accordance
                     with the terms of this Agreement and, as the case may be:

                     (a)        the Bank shall only be obliged to make available
                                to such Borrower pursuant to Clause 5.6 a
                                principal amount equal to the amount (if any) by
                                which the New Advance exceeds the Maturing
                                Advance; or

                     (b)        such Borrower shall only be obliged to pay to
                                the Bank pursuant to this Clause 8.1 a principal
                                amount equal to the


                                     -13-
<PAGE>   14

                                amount by which the Maturing Advance exceeds the
                                New Advance.

8.2        On the Final Maturity Date, all outstanding Advances and other sums
           (if any) then owing under this Agreement shall in any event be repaid
           or paid in full.

           PREPAYMENT OF ADVANCES

8.3        Any Borrower may, without penalty and on giving not less than 15
           days' prior notice to the Bank, prepay all or any part of an Advance,
           but if in part, in a minimum amount of Pound Sterling 1,000,000 and
           an  integral multiple of Pound Sterling 100,000 (or the comparable
           amount in any Optional Currency).

8.4        Any notice by a Borrower of prepayment under this Agreement is
           irrevocable.

8.5        Should any person or group of persons, acting either individually or
           in concert (as defined in the City Code on Take Overs and Mergers
           effective as at the date of this Agreement) otherwise than with the
           consent of the Bank acquire control of the Company (and for the
           purpose of this Clause a single person or group of persons shall have
           acquired control if it or they own or hold more than 50% (fifty per
           cent.) of the issued share capital of the Company having the right to
           attend and vote at general meetings of the Company or more than 50%
           (fifty per cent.) of such rights), then:

           8.5.1        the Company shall immediately upon becoming aware
                        thereof notify the Bank specifying the date of such
                        acquisition and the name of such person or persons
                        acquiring control; and

           8.5.2        thereafter no Borrower shall be permitted to request an
                        Advance unless the terms of the acquisition of control
                        of the Company were approved by the Board of Directors
                        of the Company and the Maturity Date for any Advance
                        requested falls on a date not more than three months
                        after the expiration of the 30 day period referred to
                        in Clause 8.6.

8.6        If the terms of the acquisition of control of the Company were
           approved by the Board of Directors of the Company, the Bank shall
           consult with the Company during the period of 30 days after receipt
           of the notification from the Company referred to in sub-Clause 8.5.1
           and shall be entitled to give notice of continuance of the Facility
           provided hereunder to the Company. Upon receipt of such notice of
           continuance, the right of the Borrowers to request an Advance without
           the limitation referred to in sub-Clause 8.5.2 shall be reinstated.

8.7        If the terms of the acquisition of control of the Company were
           approved by the Board of Directors of the Company but, at the end of
           the period of 30 days referred to in Clause 8.6 above, the Company
           has not received a notice of continuance then:

           8.7.1     the Facility shall be cancelled;

           8.7.2     any outstanding Advances with Maturity Dates falling later
                     than three months after the end of such period shall be
                     prepaid on the date

                                     -14-
<PAGE>   15
                     falling three months after the end of such period, together
                     with accrued interest thereon up to the date of payment and
                     all other amounts payable to the Bank hereunder; and

           8.7.3     any outstanding Advances with Maturity Dates falling not
                     later than three months after the end of such period shall
                     be repaid on their respective Maturity Dates.

8.8        If the terms of the acquisition of control of the Company were not
           approved by the Board of Directors of the Company, then unless the
           Bank shall have confirmed within 2 days of receipt of the notice
           referred to in sub-Clause 8.5.1 that the Facility shall be continued,
           the Facility shall be cancelled and any outstanding Advances shall be
           repayable on demand by the Bank together with accrued interest
           thereon up to the date of payment and all other amounts payable to
           the Bank hereunder.

8.9        Any prepayment under this Agreement shall be made together with
           accrued interest on the amount prepaid together with any amount
           payable to the Bank pursuant to Clause 22.3.

8.10       No Advance may be prepaid otherwise than in accordance with the
           express terms of this Agreement.

           PLACE

9.1        All payments by each of the Borrowers or the Bank under this
           Agreement shall be made to such account at such office or bank in the
           principal financial centre of the relevant currency as it may notify
           the other or to such other place as may be agreed between the parties
           for this purpose.

                      country of that Optional Currency, in immediately
                      available funds, or at such times or in such funds as the
                      Bank may specify to the relevant Borrower as being
                      customary at the time for the settlement of transactions
                      in the relevant currency in the place for payment.

                                     -15-
<PAGE>   16

9.3        A repayment or prepayment of an Advance is payable in the currency
           in which the Advance is denominated.

9.4        Interest is payable in the currency in which the relevant amount in
           respect of which it is payable is denominated.

9.5        Any other amount payable under this Agreement is, except as otherwise
           provided in this Agreement, payable in Sterling.

9.6        Subject to clause 9.7, on and after the Commencement Date, any
           Advance requested to be denominated in the currency of a
           Participating Member State shall be made in the euro unit.

9.7        If and to the extent that any EMU legislation provides that an amount
           denominated either in the euro unit or in the national currency unit
           of a given Participating Member State and payable within that
           Participating Member State by crediting an account of the creditor,
           can be paid by the debtor either in the euro unit or in that national
           currency unit, a Party shall be entitled to pay that amount either in
           the euro unit or in the relevant national currency unit.

           SET-OFF AND COUNTERCLAIM

9.8        All payments made by each of the Borrowers under this Agreement shall
           be made without set-off or counterclaim.

           NON-BUSINESS DAYS

9.9        If a payment under this Agreement is due on a day which is not a
           Business Day, then the due date for the payment shall instead be the
           next Business Day.

9.10       During any extension of the due date for payment of any principal
           under this Agreement pursuant to Clause 9.9 above interest is payable
           on the principal at the rate payable on the original due date.

           PARTIAL PAYMENTS

9.11       If the Bank receives a payment insufficient to discharge all the
           amounts then due and payable by any Borrower under this Agreement,
           the Bank shall apply that payment towards the obligations of such
           Borrower under this Agreement in the following order:


           9.11.1     firstly, in or towards payment of any unpaid costs and
                      expenses of the Bank under this Agreement;

           9.11.2     secondly, in or towards payment of any accrued fees due
                      but unpaid under Clause 19.2 (Commitment Fee);

           9.11.3     thirdly, in or towards payment of any accrued interest due
                      but unpaid under this Agreement;

           9.11.4     fourthly, in or towards payment of any principal due but
                      unpaid under this Agreement, and


                                     -16-
<PAGE>   17

           9.11.5     fifthly, in or towards payment of any other sum due but
                      unpaid under this Agreement.

9.12       The Bank may vary the order set out in Clauses 9.11.1 to 9.11.5
           above.

9.13       Clauses 9.11 and 9.12 above shall override any appropriation made by
           any Borrower.

10.        OPTIONAL CURRENCIES

           SELECTION

10.1       No Borrower may request an Advance denominated in an Optional
           Currency unless the Bank has confirmed to such Borrower that the
           Optional Currency is readily available and freely transferable in the
           London foreign exchange market.

           CHANGE OF CURRENCY

10.2       If, on the Rate Fixing Day of an Advance to be denominated in an
           Optional Currency, the Bank determines that:

           10.2.1     it is impracticable for reasons beyond its control for the
                      Bank to fund the Advance for its Term in that Optional
                      Currency in the ordinary course of business in the London
                      Interbank Market; or

           10.2.2     the use of the proposed Optional Currency might contravene
                      any law or regulation,
           then:

           10.2.3     the Bank shall promptly and in any event before 10.30 a.m.
                      on that Rate Fixing Day notify the relevant Borrower;

           10.2.4     if the Bank receives notice from the relevant Borrower by
                      11.30 a.m. on that Rate Fixing Day to that effect, the
                      Advance will not be made; and

           10.2.5     if the Bank does not receive any notice under sub-Clause
                      10.2.4 above, the Advance will be denominated instead in
                      Sterling in an amount equal to its Original Sterling
                      Amount.

           NOTIFICATION OF RATES AND AMOUNTS

10.3       The Bank shall, on request, promptly notify the relevant Borrower of
           any applicable Bank's Spot Rate of Exchange or Original Sterling
           Amount promptly after it has been ascertained.

10.4       If an Advance which has been drawn in an Optional Currency is
           reborrowed in the same Optional Currency immediately following its
           repayment, then the Original Sterling Amount of such new Advance
           denominated in such Optional Currency shall be recalculated for the
           new Term in accordance with the terms and conditions of this
           Agreement and if on the relevant Utilisation Date the

                                     -17-
<PAGE>   18

           aggregate Original Sterling Amount of all Advances outstanding on
           such date exceeds the Commitment, then any excess shall be repaid to
           the Bank by the relevant Borrower upon the Bank's first written
           demand.

11.        TAXES

           GROSS-UP

11.1       All payments by each of the Borrowers under this Agreement shall be
           made without any deductions and free and clear of and without
           deduction for or on account of any Relevant Taxes except to the
           extent that any Borrower is required by law to make payment subject
           to any such taxes. If any Relevant Tax or amounts in respect of any
           Relevant Tax must be deducted from any amounts payable or paid by any
           Borrower hereunder, such Borrower shall pay such additional amounts
           as may be necessary to ensure that the Bank receives a net amount
           equal to the full amount which it would have received had payment not
           been made subject to tax.

           "RELEVANT TAX" in relation to any payment which falls to be made
           hereunder means any present or future taxes of any nature now or
           hereafter imposed by the laws of (i) the United Kingdom, (ii) any
           other jurisdiction from which, or through which, such payment is made
           or to the taxation laws of which the relevant Borrower is at the time
           of such payment subject, (iii) any political sub-division of the
           United Kingdom or any such other jurisdiction or (iv) any federation
           or association of states of which the United Kingdom or any such
           other jurisdiction is, at the time of such payment, a member.

           TAX RECEIPTS

11.2       All Relevant Taxes required by law to be deducted or withheld by any
           Borrower from any amount paid or payable under this Agreement shall
           be paid by such Borrower when due (unless the obligation to pay is
           being disputed in good faith) and such Borrower shall, within 30 days
           of the payment being made, deliver to the Bank evidence satisfactory
           to the Bank (including all relevant tax receipts) that the payment
           has been duly remitted to the appropriate authority.

           TAX CREDITS

11.3       If any Borrower pays any additional amount (a "TAX PAYMENT") under
           Clause 11.1 and the Bank effectively obtains a refund of tax, or a
           relief or credit against tax by reason of that Tax Payment (a "TAX
           Credit"), and the Bank is able to identify the Tax Credit as being
           attributable to the Tax Payment, then the Bank shall reimburse to the
           relevant Borrower such amount as the Bank reasonably determines to be
           the proportion of the Tax Credit as will leave the Bank (after that
           reimbursement) in no better or worse position that it would have been
           if the Tax Payment had not been required. Nothing in this Clause
           interferes with the right of the Bank to arrange its tax affairs in
           whatever manner it thinks fit and, without prejudice to the
           foregoing, the Bank is under no obligation to claim a Tax Credit, or
           to claim a Tax Credit in priority to any other claim, relief,


                                     -18-
<PAGE>   19

           credit or deduction available to it. The Bank is not obliged to
           disclose any information regarding its tax affairs or computations to
           any Borrower.

           QUALIFYING BANK

11.4       If, otherwise than as a result of the introduction of, change in, or
           change in the interpretation, administration or application of, any
           law or regulation or any practice or concession of the Inland Revenue
           after the Signing Date, the Bank ceases to be a Qualifying Bank no
           Borrower shall be liable to pay to the Bank under Clause 11.1
           (Gross-up) any amount in respect of taxes levied or imposed by the UK
           or any taxing authority thereof or therein in excess of the amount it
           would have been obliged to pay if the Bank had been or had not ceased
           to be a Qualifying Bank.

12.        MARKET DISRUPTION

           MARKET DISRUPTION

12.1       If, in relation to any proposed Utilisation:

           12.1.1    the Bank is unable to obtain from leading banks a rate for
                     the purposes of determining the applicable LIBOR or the
                     Bank otherwise determines that adequate and fair means do
                     not exist for ascertaining the applicable LIBOR; or

           12.1.2    in the opinion of the Bank:

                     (a)     matching deposits may not be available to it in the
                             London Interbank Market in the ordinary course of
                             business to fund an Advance; or

                     (b)     the cost to it of matching deposits in the
                             London Interbank Market would be in excess of
                             the relevant LIBOR,

                     the Bank shall notify the Company by 10.30 a.m. or as soon
                     as is practicable thereafter on the Rate Fixing Day of the
                     fact and that this Clause is in operation.

12.2       After any notification under Clause 12.1 above:

           12.2.1    subject to sub-Clause 12.2.3 below the relevant Advance
                     shall be made in Sterling in an amount equal to its
                     Original Sterling Amount (unless Sterling was the original
                     currency of the relevant Advance);

           12.2.2     subject to sub-Clause 12.2.3 below, no further notices of

                     Company that the event specified in the notification no
                     longer prevails;

           12.2.3    the relevant Borrower may, by notice to the Bank by 11.00
                     a.m. (or, if later, within 30 minutes of receipt by the

                     to be cancelled without penalty; (ii) if the Advance was to

                     (iii) elect for the Advance to be made in accordance with
                     the Request notwithstanding the event specified in the
                     notification. If any Borrower requires an affected Advance
                     to be made in the original currency selected for such
                     Advance notwithstanding the event specified in the
                     notification then within five Business Days of receipt of
                     the notification, the Company and the Bank shall enter into
                     negotiations for a period of not more than 25 days with a

                     Advance and any future Advances in the currency of the
                     affected Advance provided that if no substitute basis is
                     agreed within that period:

                     (a)      the Bank shall certify to the Company (such
                              certificate to be conclusive) the alternative
                              interest rate calculated in accordance with
                              sub-Clause 12.2.4 below;

                     (b)      the certificate may make provision for different
                              funding periods and shall be retroactive to the

                     (c)      the certificate shall be binding on each
                              relevant Borrower unless the Company gives
                              notice to the Bank within five Business Days of
                              the receipt of the certificate that the
                              certificate is not acceptable and that each
                              relevant Borrower shall prepay in full the
                              relevant Advances on a Business Day specified in
                              the notice, which shall be not less than five
                              nor more than thirty days after the date of the
                              Bank's certificate to the Company; and

           12.2.4    for the purposes of sub-Clause 12.2.3(a) above the rate of
                     interest on each Advance shall be the rate certified by the
                     Bank as the rate per annum determined by the Bank to be the
                     aggregate of:

                     (a)      the Margin;

                     (b)      the rate notified by the Bank, on or before the
                              last day of its Term, as being the cost to the
                              Bank of funding the Advance from such other
                              sources as it may reasonably select; and

                     (c)      the applicable Mandatory Cost if any.

12.3       During the period when any substitute basis is in force in relation
           to a particular currency, the Bank shall periodically determine
           whether the circumstances referred to in Clause 12.1 above still
           apply and, if they do not, shall forthwith give notice in writing to
           the Company of the date on which the substitute basis will cease to
           apply.

13.        INCREASED COSTS

           INCREASED COSTS - SERVICE OF DEMAND

13.1       If the result of any introduction of or change in any law or
           regulation after the Signing Date, or of any change in the
           application or interpretation of any such changed law or regulation
           or compliance by the Bank with any such changed law or regulation
           after the Signing Date (including, without limitation, any law or
           regulation relating to taxation, any reserve, special deposit, cash
           ratio, liquidity or capital adequacy requirement or any form of
           banking or monetary control but excluding (i) changes arising from
           the implementation by any authority having jurisdiction over the Bank
           or its holding company of the matters set out in the statement
           prepared by the Basle Committee on Banking Regulations and
           Supervisory Practices dated July 1988 and entitled "International
           Convergence of Capital Measurement and Capital Standards" (as amended
           in November 1991) and (ii) changes arising from the implementation in
           whole or in part by any authority having jurisdiction over the Bank
           or its holding company of the proposals contained in the matters set
           out in the EC Directive 93/6/EEC of 15 March 1993 on the capital
           adequacy of investment firms and credit institutions) is that the
           Bank incurs an increased cost, then the Bank will promptly notify the
           Company of the relevant event and the Company shall on demand pay to
           the Bank such amount as the Bank certifies in the demand will
           compensate it for the applicable increased cost.

13.2       In this Clause 13 "INCREASED COST" means:

           13.2.1    an additional cost incurred by the Bank as a result of it
                     having entered into, or performing, maintaining or funding
                     its obligations under, this Agreement; or

           13.2.2    that portion of an additional cost incurred by the Bank in
                     making, funding or maintaining all or any advances
                     comprised in a class of advances formed by or including the
                     Advances made or to be made by it under this Agreement as
                     is attributable to it making, funding, or maintaining such
                     advances; or

           13.2.3    a reduction in any amount payable to the Bank or the
                     effective return to the Bank under this Agreement or on its
                     capital; or

           13.2.4    any payment made or interest or other return on or
                     calculated by reference to any amount received or
                     receivable by the Bank under this Agreement which is
                     forgone.

13.3       When calculating an increased cost, the Bank may allocate or spread
           costs, liabilities and losses to or across its liabilities or assets,
           or any class of liabilities or assets, and on such basis, as it
           reasonably considers appropriate.

           INCREASED COSTS - EXCEPTIONS

13.4       An increased cost does not include any increased cost:

           13.4.1    compensated for by the payment of the Mandatory Cost;

           13.4.2     compensated for by the operation of Clause 11 (Taxes);

           13.4.3     attributable to any change in the rate of tax on the
                      overall net income of the Bank (or the overall net income
                      of a division or branch of the Bank) imposed in the
                      jurisdiction in which its principal office or the relevant
                      lending office for the time being is situate;

           13.4.4     payable to an assignee or transferee of the Bank at the
                      time of an assignment, transfer or novation under Clause
                      25 (Changes to the Parties), but only to the extent that
                      the increased cost would not have been payable to the
                      assigning, transferring or novating Bank; or

           13.4.5     which is attributable to the introduction of the euro
                      other than an increased cost which is being incurred
                      generally by banks transacting euro business in the London
                      interbank market.

14.        ILLEGALITY

14.1       If it is or becomes unlawful for the Bank to give effect to any of
           its obligations as contemplated by this Agreement or to fund or
           maintain any Advance, then the Bank shall notify the Company
           accordingly and on the Maturity Date of each relevant Advance (or
           such earlier date as the relevant law or directive may require) the
           relevant Borrower shall repay or prepay, as the case may be, any
           Advances made to it by the Bank together with all other amounts
           payable by it to the Bank under this Agreement.

14.2       The Bank's Commitment shall be cancelled on the date of a
           notification under Clause 14.1 above.

15.        TAXES AND INCREASED COSTS - ADDITIONAL RIGHTS

           PREPAYMENT AND CANCELLATIONS

15.1       If any Borrower is required to pay any additional amounts to the Bank
           under Clause 11 (Taxes) or compensation under Clause 13 (Increased
           Costs), the Company may, whilst the circumstances giving rise to the
           requirement continue, serve a notice of prepayment and cancellation
           in relation to all or all affected Advances on the Bank.

15.2       On the tenth Business Day after the date of service of the notice the
           relevant Borrower shall prepay the relevant Advance or Advances made
           to it by the Bank together with all other amounts in relation to such
           Advance(s) payable by it to the Bank under this Agreement.

15.3       To the extent of the Advances referred to in the notice of prepayment
           and cancellation, but not further or otherwise, the Bank's Commitment
           shall be cancelled on the date of service of the notice.

           MITIGATION

15.4       If, in respect of the Bank, circumstances arise which would or would,
           with the giving of notice, result in:

           15.4.1     any additional amounts becoming payable under Clause 11
                      (Taxes); or

           15.4.2     any increased cost becoming payable under Clause 13
                      (Increased Costs); or

           15.4.3     any prepayment, payment or cancellation under Clause 14
                      (Illegality),

           then the Bank shall endeavour to take such steps as are reasonably
           open to it to mitigate or remove those circumstances (including
           seeking recovery for the account of the relevant Borrower where
           reasonably practicable and/or transferring its rights and obligations
           under this Agreement to another bank or financial institution
           acceptable to the Company).

15.5       Clause 15.4 above does not:

           15.5.1     prejudice the obligations of any Borrower under this
                      Agreement (including, without limitation, under the
                      Clauses referred to in Clause 15.4 above); or

           15.5.2     require the Bank to take any action which, in its opinion,
                      might be in any way prejudicial to it or conflict with its
                      banking policies.

           EVENTS OF DEFAULT

18.1       Each of the events set out in Clauses 18.2 to 18.13 (inclusive) is an
           Event of Default (whether or not caused by any reason whatsoever
           outside the control of the relevant Borrower or any other person),
           except that if any of the events specified in Clauses 18.6 to 18.13
           (inclusive) occurs in relation to a Material Subsidiary which is not
           a Borrower it will only be an Event of Default if the event is, in
           the reasonable opinion of the Bank, reasonably likely to affect
           materially and adversely the Company's ability to perform its
           obligations under this Agreement.

           NON-PAYMENT

18.2       Any Borrower defaults in payment on the due date of any amount

           BREACH OF OTHER OBLIGATIONS

18.3       Any Borrower fails to observe or perform any other obligation on its
           part contained in this Agreement (other than those which, in the
           reasonable opinion of the Bank, are not material), and (in the case
           of a breach capable of being remedied) fails to remedy the breach
           within fourteen Business Days after the date on which the Company and
           the relevant Borrower receive notice of the breach from the Bank.

           MISREPRESENTATION

18.4       A representation, warranty or statement made or repeated in, this

           they fall due; or

18.7       Any Borrower or Material Subsidiary suspends making payments on all

           on all, or substantially all, of its business.

           ACCELERATION

                     any of its obligations hereunder being or becoming illegal,
                     invalid, unenforceable or ineffective in any respect;

           22.7.3    time or other indulgence being granted or agreed to be
                     granted to any Borrower in respect of its obligations
                     hereunder or under any other security;

          22.7.4     any amendment, supplement or modification to, or any waiver
                     of or release of any obligation of any Borrower hereunder
                     or under any such other security;

          22.7.5     any failure to take, or fully to take, any security
                     contemplated hereby or otherwise agreed to be taken in
                     respect of any Borrower's obligations hereunder;

          22.7.6     any failure to realise or fully to realise the value of, or

                     security taken in respect of any Borrower's obligations
                     hereunder; or

          22.7.7     any other act, event or omission including, (without
                     limitation, any amendment to this Agreement) which, but for
                     this Clause 22.7 might operate to discharge, impair or
                     otherwise affect any of the obligations of the Borrowers or
                     the Company herein contained or any of the rights, powers
                     or remedies conferred upon the Bank by this Agreement or by
                     law.

22.8       Any settlement or discharge between the Company and the Bank shall be
           conditional upon no security or payment to the Bank by any Borrower
           or any other person being avoided or reduced by virtue of any
           provisions or enactments relating to bankruptcy, insolvency,
           liquidation or similar laws of general application for the time being
           in force and, if any such security or payment is so avoided or
           reduced, the Bank shall be entitled to recover the value or amount of
           such security or payment from the Company subsequently as if such
           settlement or discharge had not occurred.

22.9       The Bank shall not be obliged before exercising any of the rights,
           powers or remedies conferred upon them in respect of the Borrowers or
           the Company by this Agreement or by law:

           22.9.1    to make any demand of any other Borrower;

           22.9.2    to take any action or obtain judgment in any court against

           22.9.3    to make or file any claim or proof in a winding-up or
                     dissolution of any Borrower; or

           22.9.4    to enforce or seek to enforce any other security taken in
                     respect of any of the obligations of any other Borrower
                     hereunder.

22.10      The Company agrees that, so long as any amounts are or may be owed by
           any Borrower hereunder or any Borrower is under any actual or
           contingent obligations hereunder, it shall not exercise any rights
           which it may at any time have by reason of performance by it of its
           obligations hereunder:

           22.10.1   to be indemnified by any other Borrower; and/or

           22.10.2   to claim any contribution from any other Borrower; and/or;

                     of subrogation or otherwise) of any rights of the Bank
                     hereunder or of any other security taken pursuant to, or in
                     connection with, this Agreement by the Bank; and/or

           22.10.4   to make or file any claim or proof in a winding-up or

                     rights arising by reason of or in connection with the
                     performance by it of its obligations hereunder.

           elapsed and a year of 365 days, or, in the case of interest payable

           not be required where the assignee or transferee is an Affiliate of
           the Bank which is a Qualifying Bank.

25.3       If the Bank proposes to enter into any kind of transfer,

           or other agreement in relation to this Agreement:

           26.1.1    a copy of this Agreement; and

27.1       The rights of the Bank under this Agreement:

           27.1.1    may be exercised as often as necessary;

27.2       Any delay by the Bank in exercise of any of its rights under this

28.        SET-OFF

28.1       The Bank may set off any matured obligation owed by any Borrower
           under this Agreement against any obligations (whether or not matured)

<PAGE>   36

           to such Borrower, regardless of the place of payment, booking branch
           or currency of either obligation. If the obligations are in different
           currencies, the Bank may convert either obligation at the Bank's Spot
           Rate of Exchange for the purpose of the set-off.

29.        SEVERABILITY

29.1       If a provision of this Agreement is or becomes illegal, invalid or
           unenforceable in any jurisdiction, that shall not affect:

           29.1.1    the legality, validity or enforceability in that
                     jurisdiction of any other provision of this Agreement; or

31.        DESIGNATION OF ACCEDING AND SECEDING BORROWERS

31.1       The Company may request that any of its Subsidiaries incorporated in
           England and Wales and, with the prior written consent of the Bank
           (such consent not to be unreasonably withheld or delayed) any other
           Subsidiary of the Company becomes an Acceding Borrower by delivering
           or procuring the delivery to the Bank a Borrower's Accession Notice
           duly executed by the Company and the relevant Subsidiary provided
           that if such Subsidiary is not resident in the United Kingdom for tax
           purposes the Company and the Bank agree to make such amendments to
           this Agreement as may be reasonably required at the time in order to
           allow such Subsidiary to pay interest to the Bank without deduction
           or withholding of any Relevant Tax and to provide such Subsidiary
           with equivalent rights, mutatis mutandis, to those contained in
           Clause 11.4 (Qualifying Bank).

31.2       Upon delivery of a Borrower's Accession Notice, the relevant
           Subsidiary shall become an Acceding Borrower and shall, subject to
           the terms and conditions of this Agreement acquire all the rights and
           assume all the obligations of a Borrower hereunder provided that the
           Bank has confirmed to the Company that it has received, in form and
           substance satisfactory to it, all the documents set out in Part II of
           Schedule 1.

31.3       The Company undertakes that it shall procure that each Acceding
           Borrower shall provide the Bank with each of the documents listed in
           Part II of Schedule 1.

31.4       If at any time any Borrower (other than the Company) has no actual or
           contingent obligation under this Agreement, the Company may deliver a

                                     -37-
<PAGE>   38

           Borrower's Cessation Notice to the Bank in which event such Borrower
           shall forthwith cease to be a Borrower upon receipt by the Bank of
           such notice.

32.        CHANGE OF CURRENCY

32.1       If more than one currency or currency unit are at the same time
           recognised by the central bank of any country as the lawful currency
           of that country, then:

           32.1.1    any reference in this Agreement to, and any obligations
                     arising under this Agreement in, the currency of that
                     country shall be translated into, or paid in, the currency
                     unit of that country designated by the Bank acting
                     reasonably and in consultation with the Company; and

           32.1.2    any translation from one currency unit to another shall be
                     at the official rate of exchange recognised by the relevant
                     central bank for the conversion of that currency or
                     currency unit into the other, rounded up or down by the
                     Bank acting reasonably.

32.2       If a change in any currency of a country occurs, the Bank and the
           Company will negotiate in good faith in order to agree any amendments
           to this Agreement to reflect market practice at that time with regard
           to the occurrence of EMU within the European Union or any part(s) of
           it and the new currency and to put the Bank and the Borrowers in the
           same position, so far as is possible, that they would have been in if
           no change in currency had occurred.

32.3       The Bank and the Company agree that the occurrence or non-occurrence
           of EMU within the European Union or part(s) of it and/or any event or
           events associated with EMU and/or the introduction of any new
           currency in all or any part of the European Union will not result in
           the discharge cancellation, rescission or termination in whole or in
           pat of this Agreement or give any party hereto the right to cancel,
           rescind, terminate or vary (other than as aforesaid) this Agreement
           in whole or in part or give rise to an Event of Default.

33.        COUNTERPARTS

           This Agreement may be executed in any number of counterparts each of
           which shall be an original and all of such counterparts taken
           together shall be delivered to constitute one and the same
           instrument.

34.        APPLICABLE LAW AND JURISDICTION

34.1       The law of England and Wales is the law applicable to this Agreement.

34.2       Each of the Borrowers irrevocably agrees for the benefit of the Bank
           that the courts of England shall have jurisdiction to hear and
           determine any suit, action or proceeding, and to settle any disputes,
           which may arise out of or in connection with this Agreement and, for
           such purposes, irrevocably submits to the jurisdiction of such
           courts.

                                     -38-
<PAGE>   39

34.3       Each of the Borrowers which is not incorporated in England and Wales
           agrees that the process by which any suit, action or proceeding is
           begun in England and Wales may be served on it by being delivered to
           the Company at its registered office for the time being and hereby
           appoints the Company (and the Company accepts such appointment) for
           such purposes. If the appointment of the person mentioned in this
           Clause 34.3 ceases to be effective in respect of any or all of the
           Borrowers such Borrower or Borrowers shall immediately appoint a
           further person in England and Wales to accept service of process on
           its behalf in England and Wales and, failing such appointment within
           fifteen days, the Bank acting reasonably shall be entitled to appoint
           such a person by notice to such Borrower or Borrowers. Nothing
           contained herein shall affect the right to serve process in any other
           manner permitted by law.

34.4       Each of the Borrowers irrevocably waives any objection which it might
           now or hereafter have to the courts referred to in Clause 34.2 being
           nominated as the forum to hear and determine any suit, action or
           proceeding, and to settle any disputes, which may arise out of or in
           connection with this Agreement and agrees not to claim that any such
           court is not a convenient or appropriate forum.

34.5       The submission to the jurisdiction of the courts referred to in
           Clause 34.2 shall not (and shall not be construed so as to) limit the
           right of the Bank to take proceedings against any of the Borrowers in
           any other court of competent jurisdiction nor shall the taking of
           proceedings in any one or more jurisdictions preclude the taking of
           proceedings in any other jurisdiction (whether concurrently or not)
           if and to the extent permitted by applicable law.

This Agreement has been entered into on the date stated at the beginning of this
Agreement.

2.         NATURE OF THE FACILITY

           FACILITY

2.1        The Bank grants to the Borrowers a revolving multi-currency advances
           facility under which the Bank shall, during the Availability Period
           and when requested by a Borrower, make to such Borrower Advances upon
           and subject to the terms of this Agreement.

           OVERALL FACILITY LIMIT

2.2        The aggregate Original Sterling Amount of all outstanding Advances
           shall not at any time exceed the Commitment at that time.

           NUMBER OF REQUESTS AND UTILISATIONS

2.3        Any number of Requests may be delivered on the same day and/or
           specifying the same Utilisation Date, whether or not the currencies
           and Terms requested are similar.

3.         PURPOSE

3.1        Each Borrower shall apply each Utilisation made to it towards the
           general corporate purposes of the Group.

3.2        Without affecting the obligations of any of the Borrowers in any way,
           the Bank shall not be bound to monitor or verify the application of
           the proceeds of any Utilisation.

4.         CONDITIONS PRECEDENT

           DOCUMENTARY CONDITIONS PRECEDENT

4.1        The obligations of the Bank to the Borrowers under this Agreement are
           subject to the condition precedent that the Bank has notified the
           Company that it has received, not later than 3 Business Days prior to
           the first Utilisation Date, all of the documents set out in Part I of
           Schedule 1 in form and substance satisfactory to the Bank.

           FURTHER CONDITIONS PRECEDENT

4.2        The obligation of the Bank to make each Utilisation is subject to the
           further conditions precedent that:

                                       -9-
<PAGE>   10

           4.2.1     on both the date of the Request and the Utilisation Date
                     for that Utilisation:

                     (a)    the representations and warranties in Clause 16
                            (Representations and Warranties) to be repeated on
                            those dates are correct and will be correct
                            immediately after the Utilisation; and

                     (b)    no Default is outstanding or might result from the
                            Utilisation; and

           4.2.2     the Utilisation would not cause Clause 2.2 (Overall
                     facility limit) to be contravened.

           4.2.3     in the case of the first Utilisation either:

                     (a)    the total aggregate amounts outstanding under the
                            Revolving Multi-Currency Credit Facility Agreement
                            dated 17th May 1993 (as amended) made between the
                            Company and the Bank, the "Existing Outstandings",
                            shall have been repaid or prepaid in full and the
                            aggregate commitments under such facility agreement
                            cancelled on the day of such repayment or
                            prepayment; or

                     (b)    the amount of the first Utilisation together with
                            other sums available to the Borrower shall be used
                            to repay or prepay the Existing Outstandings and the
                            aggregate commitments under such facility agreement
                            cancelled on the day of such repayment or
                            prepayment.

           THE LOAN FACILITY

           RECEIPT OF REQUESTS FOR ADVANCES

5.1        Any Borrower may utilise the Facility if the Bank receives, not later

           Signatory of the relevant Borrower.

5.2        Any Borrower may utilise the Loan Facility by notifying the Bank by
           telephone not later than 10.00 a.m. on the Rate Fixing Day provided

           delivery by the relevant Borrower to the Bank of a duly completed
           Request to be actually received by the Bank not later than the close
           of business in London on the day on which such telephone notice is,
           or is deemed to have been, given.

5.3        When giving a notice of Utilisation by telephone and when completing
           the Request, the relevant Borrower must ensure that:

<PAGE>   11

           5.3.1     the Utilisation Date is a Business Day;

                     (c)    if the currency is an Optional Currency other than
                            Dollars, a minimum and integral multiple of the
                            amounts agreed between the relevant Borrower and the
                            Bank before the telephone notice of Utilisation or
                            delivery of that Request; or

                     (d)    such other amounts as the Bank and the relevant

5.4        If the relevant Borrower selects a Term of an optional duration, it
           may also select at the time of the telephone notice of Utilisation
           and in the relevant Request a Term of any approved duration to apply
           if the selection of a Term of an optional duration becomes
           ineffective in accordance with Clause 5.5.2.

5.5        If:

           5.5.1     the relevant Borrower requests a Term of an optional

                     request,

           the Term for the proposed Utilisation shall be the alternative period
           specified in the telephone notice of Utilisation or the relevant

           INTEREST RATE

7.1        The rate of interest on each Advance for its Term is the rate per

           DEFAULT INTEREST

7.3        If any Borrower fails to pay any amount payable by it under this
           Agreement, it shall, on demand by the Bank from time to time, pay
           interest on the overdue amount from the due date up to the date of
           actual payment, after as well as before judgment, at a rate (the
           "DEFAULT RATE") determined by the Bank to be one (1) per cent. per
           annum above the higher of:

           7.3.1     the rate on the overdue amount under Clause 7.1 (Interest
                     rate) immediately before the due date (but only if the
                     overdue amount is an Advance (or part thereof) and only for
                     the period up to and including the Maturity Date of that
                     Advance); and

           7.3.2     the rate which would have been payable if the overdue
                     amount had, during the period of non-payment, constituted
                     an Advance in the currency of the overdue amount for such
                     successive Terms of such duration (not exceeding three
                     months) as the Bank may reasonably determine (each a
                     "DESIGNATED TERM").

7.4        The default rate will be determined on the first day of, or two
           Business Days before the first day of, the relevant Designated Term,
           as appropriate.

7.5        If the Bank determines that deposits in the currency of the overdue
           amount are not at the relevant time being made available by leading
           banks in the London Interbank Market, the default rate will be
           determined by reference to the cost of funds to the Bank from
           whatever sources it may reasonably select.

7.6        Default interest shall be compounded at the end of each Designated
           Term until it is paid.

           NOTIFICATION OF RATES OF INTEREST

7.7        The Bank shall promptly notify the relevant Borrower of the
           determination of any applicable rate of interest under this
           Agreement.

8.         REPAYMENT AND PREPAYMENT

           REPAYMENT OF ADVANCES

8.1        Each Borrower shall repay each Advance made to it in full on its
           Maturity Date to the Bank. If an Advance (the "NEW ADVANCE") is to be
           made to a Borrower on the day on which another Advance (the "MATURING
           ADVANCE") in the same currency is due to be repaid by such Borrower
           then, subject to the terms of this Agreement and so long as the
           conditions referred to in Clause 4.2 shall have been satisfied in
           relation to the New Advance:

           8.1.1     the Maturing Advance shall be deemed to have been repaid on
                     its Maturity Date either in whole (if the New Advance is
                     equal to or greater than the Maturing Advance) or in part
                     (if the New Advance is less than the Maturing Advance); and


                                      -13-
<PAGE>   14


             8.1.2   to the extent that a Maturing Advance is so deemed
                     to have been repaid, the principal amount of the New
                     Advance to be made on such a date shall be deemed to
                     have been credited to the account of such Borrower
                     by the Bank in accordance with the terms of this
                     Agreement and, as the case may be:

                     (a)    the Bank shall only be obliged to make available to
                            such Borrower pursuant to Clause 5.6 a principal
                            amount equal to the amount (if any) by which the New
                            Advance exceeds the Maturing Advance; or

                     (b)    such Borrower shall only be obliged to pay to the
                            Bank pursuant to this Clause 8.1 a principal amount
                            equal to the amount by which the Maturing Advance
                            exceeds the New Advance.

8.2        On the Final Maturity Date, all outstanding Advances and other sums
           (if any) then owing under this Agreement shall in any event be repaid
           or paid in full.

           PREPAYMENT OF ADVANCES

8.3        Any Borrower may, without penalty and on giving not less than 15
           days' prior notice to the Bank, prepay all or any part of an Advance,
           but if in part, in a minimum amount of Pound Sterling 1,000,000 and
           an integral multiple of Pound Sterling 100,000 (or the comparable
           amount in any Optional Currency).

8.4        Any notice by a Borrower of prepayment under this Agreement is
           irrevocable.

8.5        Should any person or group of persons, acting either individually or
           in concert (as defined in the City Code on Take Overs and Mergers
           effective as at the date of this Agreement) otherwise than with the
           consent of the Bank acquire control of the Company (and for the
           purpose of this Clause a single person or group of persons shall have
           acquired control if it or they own or hold more than 50% (fifty per
           cent.) of the issued share capital of the Company having the right to
           attend and vote at general meetings of the Company or more than 50%
           (fifty per cent.) of such rights), then:

           8.5.1     the Company shall immediately upon becoming aware thereof
                     notify the Bank;

           8.5.2     whereupon, unless the Bank otherwise agrees, the Facility
                     shall be cancelled and all outstanding Advances shall be
                     repaid on or before the date falling 30 days after the date
                     the Bank receives the notification from the Company
                     referred to in sub-clause 8.5.1 together with accrued
                     interest thereon up to the date of payment and all other
                     amounts payable to the Bank hereunder.


8.6        Any prepayment under this Agreement shall be made together with
           accrued interest on the amount prepaid together with any amount
           payable to the Bank pursuant to Clause 22.3.

                     funds, or at such times or in such funds as the Bank may
                     specify to the relevant Borrower as being customary at the
                     time for the settlement of transactions in the relevant
                     currency in the place for payment.

           CURRENCY

           Subject to clauses 9.6 and 9.7:

9.3        A repayment or prepayment of an Advance is payable in the currency in

           Participating Member State by crediting an account of the creditor,

           SET-OFF AND COUNTERCLAIM

9.8        All payments made by each of the Borrowers under this Agreement shall
           be made without set-off or counterclaim.

           NON-BUSINESS DAYS

9.9        If a payment under this Agreement is due on a day which is not a
           Business Day, then the due date for the payment shall instead be the
           next Business Day.

9.10       During any extension of the due date for payment of any principal
           under this Agreement pursuant to Clause 9.9 above interest is payable
           on the principal at the rate payable on the original due date.

           PARTIAL PAYMENTS

9.11       If the Bank receives a payment insufficient to discharge all the
           amounts then due and payable by any Borrower under this Agreement,
           the Bank shall apply that payment towards the obligations of such
           Borrower under this Agreement in the following order:

           9.11.1  firstly, in or towards payment of any unpaid costs
                   and expenses of the Bank under this Agreement;

           9.11.2  secondly, in or towards payment of any accrued fees
                   due but unpaid under Clause 19.2 (Commitment Fee);

           9.11.3  thirdly, in or towards payment of any accrued
                   interest due but unpaid under this Agreement;

           9.11.4  fourthly, in or towards payment of any principal due
                   but unpaid under this Agreement, and

           9.11.5  fifthly, in or towards payment of any other sum due
                   but unpaid under this Agreement.

9.12       The Bank may vary the order set out in Clauses 9.11.1 to 9.11.5 above

9.13       Clauses 9.11 and 9.12 above shall override any appropriation made by
           any Borrower.

10.        OPTIONAL CURRENCIES

           SELECTION

10.1       No Borrower may request an Advance denominated in an Optional
           Currency unless the Bank has confirmed to such Borrower that the
           Optional Currency is readily available and freely transferable in the
           London foreign exchange market.


                                      -16-
<PAGE>   17

           CHANGE OF CURRENCY

10.2       If, on the Rate Fixing Day of an Advance to be denominated in an
           Optional Currency, the Bank determines that:

           10.2.1    it is impracticable for reasons beyond its control for the
                     Bank to fund the Advance for its Term in that Optional
                     Currency in the ordinary course of business in the London
                     Interbank Market; or

           10.2.2    the use of the proposed Optional Currency might
                     contravene any law or regulation,

           then:

           10.2.3    the Bank shall promptly and in any event before 10.30 a.m.
                     on that Rate Fixing Day notify the relevant Borrower;

           10.2.4    if the Bank receives notice from the relevant Borrower by
                     11.30 a.m. on that Rate Fixing Day to that effect, the
                     Advance will not be made; and

           10.2.5    if the Bank does not receive any notice under sub-Clause
                     10.2.4 above, the Advance will be denominated instead in
                     Sterling in an amount equal to its Original Sterling
                     Amount.

           NOTIFICATION OF RATES AND AMOUNTS

10.3       The Bank shall, on request, promptly notify the relevant Borrower of
           any applicable Bank's Spot Rate of Exchange or Original Sterling
           Amount promptly after it has been ascertained.

10.4       If an Advance which has been drawn in an Optional Currency is
           reborrowed in the same Optional Currency immediately following its
           repayment, then the Original Sterling Amount of such new Advance
           denominated in such Optional Currency shall be recalculated for the
           new Term in accordance with the terms and conditions of this
           Agreement and if on the relevant Utilisation Date the aggregate
           Original Sterling Amount of all Advances outstanding on such date
           exceeds the Commitment, then any excess shall be repaid to the Bank
           by the relevant Borrower upon the Bank's first written demand.

11.        TAXES

           GROSS-UP

11.1       All payments by each of the Borrowers under this Agreement shall be
           made without any deductions and free and clear of and without
           deduction for or on account of any Relevant Taxes except to the
           extent that any Borrower is required by law to make payment subject
           to any such taxes. If any Relevant Tax or amounts in respect of any
           Relevant Tax must be deducted from any amounts payable or paid by any
           Borrower hereunder, such Borrower shall pay such additional amounts
           as may be necessary to ensure that the Bank receives


                                      -17-
<PAGE>   18
           a net amount equal to the full amount which it would have received
           had payment not been made subject to tax.

           "RELEVANT TAX" in relation to any payment which falls to be made
           hereunder means any present or future taxes of any nature now or
           hereafter imposed by the laws of (i) the United Kingdom, (ii) any
           other jurisdiction from which, or through which, such payment is made
           or to the taxation laws of which the relevant Borrower is at the time
           of such payment subject, (iii) any political sub-division of the
           United Kingdom or any such other jurisdiction or (iv) any federation
           or association of states of which the United Kingdom or any such
           other jurisdiction is, at the time of such payment, a member.

           TAX RECEIPTS

11.2       All Relevant Taxes required by law to be deducted or withheld by any
           Borrower from any amount paid or payable under this Agreement shall
           be paid by such Borrower when due (unless the obligation to pay is
           being disputed in good faith) and such Borrower shall, within 30 days
           of the payment being made, deliver to the Bank evidence satisfactory
           to the Bank (including all relevant tax receipts) that the payment
           has been duly remitted to the appropriate authority.

           TAX CREDITS

11.3       If any Borrower pays any additional amount (a "TAX PAYMENT") under
           Clause 11.1 and the Bank effectively obtains a refund of tax, or a
           relief or credit against tax by reason of that Tax Payment (a "TAX
           CREDIT"), and the Bank is able to identify the Tax Credit as being
           attributable to the Tax Payment, then the Bank shall reimburse to the
           relevant Borrower such amount as the Bank reasonably determines to be
           the proportion of the Tax Credit as will leave the Bank (after that
           reimbursement) in no better or worse position that it would have been
           if the Tax Payment had not been required. Nothing in this Clause
           interferes with the right of the Bank to arrange its tax affairs in
           whatever manner it thinks fit and, without prejudice to the
           foregoing, the Bank is under no obligation to claim a Tax Credit, or
           to claim a Tax Credit in priority to any other claim, relief, credit
           or deduction available to it. The Bank is not obliged to disclose any
           information regarding its tax affairs or computations to any
           Borrower.

           QUALIFYING BANK

11.4       If, otherwise than as a result of the introduction of, change in, or
           change in the interpretation, administration or application of, any
           law or regulation or any practice or concession of the Inland Revenue
           after the Signing Date, the Bank ceases to be a Qualifying Bank no
           Borrower shall be liable to pay to the Bank under Clause 11.1
           (Gross-up) any amount in respect of taxes levied or imposed by the UK
           or any taxing authority thereof or therein in excess of the amount it
           would have been obliged to pay if the Bank had been or had not ceased
           to be a Qualifying Bank.

12.        MARKET DISRUPTION

           MARKET DISRUPTION

12.1       If, in relation to any proposed Utilisation:

           12.1.1    the Bank is unable to obtain from leading banks a rate for
                     the purposes of determining the applicable LIBOR or the
                     Bank otherwise determines that adequate and fair means do
                     not exist for ascertaining the applicable LIBOR; or

           12.1.2    in the opinion of the Bank:

                     (a)    matching deposits may not be available to it in the
                            London Interbank Market in the ordinary course of
                            business to fund an Advance; or

                     (b)    the cost to it of matching deposits in the London
                            Interbank Market would be in excess of the relevant
                            LIBOR,

                     the Bank shall notify the Company by 10.30 a.m. or as soon
                     as is practicable thereafter on the Rate Fixing Day of the
                     fact and that this Clause is in operation.

12.2       After any notification under Clause 12.1 above:

           12.2.1    subject to sub-Clause 12.2.3 below the relevant Advance
                     shall be made in Sterling in an amount equal to its
                     Original Sterling Amount (unless Sterling was the original
                     currency of the relevant Advance);

           12.2.2    subject to sub-Clause 12.2.3 below, no further notices of
                     Utilisation by telephone or Requests for Advances to be
                     denominated in the original currency of the affected
                     Advance may be delivered until the Bank notifies the
                     Company that the event specified in the notification no
                     longer prevails;

           12.2.3    the relevant Borrower may, by notice to the Bank by 11.00
                     a.m. (or, if later, within 30 minutes of receipt by the
                     Company of a notification under sub-Clause 12.1.2) on the
                     Rate Fixing Day: (i) elect for the notice of Utilisation by
                     telephone or the Request to be cancelled without penalty;
                     (ii) if the Advance was to be made in an Optional Currency,
                     elect for the Advance to be made in an Optional Currency
                     other than a currency affected by the event specified in
                     the notification or (iii) elect for the Advance to be made
                     in accordance with the Request notwithstanding the event
                     specified in the notification. If any Borrower requires an
                     affected Advance to be made in the original currency
                     selected for such Advance notwithstanding the event
                     specified in the notification then within five Business
                     Days of receipt of the notification, the Company and the
                     Bank shall enter into negotiations for a period of not more
                     than 25 days with a view to agreeing a substitute basis for
                     determining the rate of interest and/or funding applicable
                     to the affected Advance and any



                                      -19-
<PAGE>   20
                    future Advances in the currency of the affected Advance
                    provided that if no substitute basis is agreed within that
                    period:

                     (a)    the Bank shall certify to the Company (such
                            certificate to be conclusive) the alternative
                            interest rate calculated in accordance with
                            sub-Clause 12.2.4 below;

                     (b)    the certificate may make provision for different
                            funding periods and shall be retroactive to the
                            beginning of the then current Term; and

                     (c)    the certificate shall be binding on each relevant
                            Borrower unless the Company gives notice to the Bank
                            within five Business Days of the receipt of the
                            certificate that the certificate is not acceptable
                            and that each relevant Borrower shall prepay in full
                            the relevant Advances on a Business Day specified in
                            the notice, which shall be not less than five nor
                            more than thirty days after the date of the Bank's
                            certificate to the Company; and

           12.2.4    for the purposes of sub-Clause 12.2.3(a) above the rate of
                     interest on each Advance shall be the rate certified by the
                     Bank as the rate per annum determined by the Bank to be the
                     aggregate of:

                     (a)    the Margin;

                     (b)    the rate notified by the Bank, on or before the last
                            day of its Term, as being the cost to the Bank of
                            funding the Advance from such other sources as it
                            may reasonably select; and

                     (c)    the applicable Mandatory Cost if any.

12.3       During the period when any substitute basis is in force in relation
           to a particular currency, the Bank shall periodically determine
           whether the circumstances referred to in Clause 12.1 above still
           apply and, if they do not, shall forthwith give notice in writing to
           the Company of the date on which the substitute basis will cease to
           apply.

13.        INCREASED COSTS

           INCREASED COSTS - SERVICE OF DEMAND

13.1       If the result of any introduction of or change in any law or
           regulation after the Signing Date, or of any change in the
           application or interpretation of any such changed law or regulation
           or compliance by the Bank with any such changed law or regulation
           after the Signing Date (including, without limitation, any law or
           regulation relating to taxation, any reserve, special deposit, cash
           ratio, liquidity or capital adequacy requirement or any form of
           banking or monetary control but excluding (i) changes arising from
           the implementation by any authority having jurisdiction over the Bank
           or its holding company of the matters set out in the statement
           prepared by the Basle Committee on Banking Regulations and
           Supervisory Practices dated July 1988 and entitled

           Standards" (as amended in November 1991) and (ii) changes arising
           from the implementation in whole or in part by any authority having

           March 1993 on the capital adequacy of investment firms and credit
           institutions) is that the Bank incurs an increased cost, then the
           Bank will promptly notify the Company of the relevant event and the
           Company shall on demand pay to the Bank such amount as the Bank
           certifies in the demand will compensate it for the applicable
           increased cost.


13.2       In this Clause 13 "INCREASED COST" means:

           13.2.1    an additional cost incurred by the Bank as a result of it
                     having entered into, or performing, maintaining or funding
                     its obligations under, this Agreement; or

           13.2.2    that portion of an additional cost incurred by the Bank in
                     making, funding or maintaining all or any advances
                     comprised in a class of advances formed by or including the
                     Advances made or to be made by it under this Agreement as
                     is attributable to it making, funding, or maintaining such
                     advances; or

           13.2.3    a reduction in any amount payable to the Bank or the
                     effective return to the Bank under this Agreement or on its
                     capital; or

           13.2.4    any payment made or interest or other return on or
                     calculated by reference to any amount received or
                     receivable by the Bank under this Agreement which is
                     forgone.

13.3       When calculating an increased cost, the Bank may allocate or spread
           costs, liabilities and losses to or across its liabilities or assets,
           or any class of liabilities or assets, and on such basis, as it
           reasonably considers appropriate.

                     increased cost would not have been payable to the
                     assigning, transferring or novating Bank; or

           its obligations as contemplated by this Agreement or to fund or

           accordingly and on the Maturity Date of each relevant Advance (or
           such earlier date as the relevant law or directive may require) the
           relevant Borrower shall repay or prepay, as the case may be, any
           Advances made to it by the Bank together with all other amounts
           payable by it to the Bank under this Agreement.

15.        TAXES AND INCREASED COSTS - ADDITIONAL RIGHTS

           PREPAYMENT AND CANCELLATIONS

           under Clause 11 (Taxes) or compensation under Clause 13 (Increased

           requirement continue, serve a notice of prepayment and cancellation
           in relation to all or all affected Advances on the Bank.

15.2       On the tenth Business Day after the date of service of the notice the
           relevant Borrower shall prepay the relevant Advance or Advances made
           to it by the Bank together with all other amounts in relation to such
           Advance(s) payable by it to the Bank under this Agreement.

15.4       If, in respect of the Bank, circumstances arise which would or would,
           with the giving of notice, result
           in:

           15.4.1    any additional amounts becoming payable under Clause 11
                     (Taxes); or

           15.4.2    any increased cost becoming payable under Clause 13
                     (Increased Costs); or

           open to it to mitigate or remove those circumstances (including
           seeking recovery for the account of the relevant Borrower where
           reasonably practicable and/or

           15.5.2    require the Bank to take any action which, in its opinion,

31.        DESIGNATION OF ACCEDING AND SECEDING BORROWERS

31.1       The Company may request that any of its Subsidiaries incorporated in
           England and Wales and, with the prior written consent of the Bank
           (such consent not to be unreasonably withheld or delayed) any other
           Subsidiary of the Company becomes an Acceding Borrower by delivering
           or procuring the delivery to the Bank a Borrower's Accession Notice
           duly executed by the Company and the relevant Subsidiary provided
           that if such Subsidiary is not resident in the United Kingdom for tax
           purposes the Company and the Bank agree to make such amendments to
           this Agreement as may be reasonably required at the time in order to
           allow such Subsidiary to pay interest to the Bank without deduction
           or withholding of any Relevant Tax and to provide such Subsidiary
           with equivalent rights, mutatis mutandis, to those contained in
           Clause 11.4 (Qualifying Bank).

31.2       Upon delivery of a Borrower's Accession Notice, the relevant
           Subsidiary shall become an Acceding Borrower and shall, subject to
           the terms and conditions of this Agreement acquire all the rights and
           assume all the obligations of a Borrower hereunder provided that the
           Bank has confirmed to the Company


                                      -37-
<PAGE>   38
           that it has received, in form and substance satisfactory to it, all
           the documents set out in Part II of Schedule 1.

31.3       The Company undertakes that it shall procure that each Acceding
           Borrower shall provide the Bank with each of the documents listed in
           Part II of Schedule 1.

31.4       If at any time any Borrower (other than the Company) has no actual or
           contingent obligation under this Agreement, the Company may deliver a
           Borrower's Cessation Notice to the Bank in which event such Borrower
           shall forthwith cease to be a Borrower upon receipt by the Bank of
           such notice.

32.        CHANGE OF CURRENCY

32.1       If more than one currency or currency unit are at the same time
           recognised by the central bank of any country as the lawful currency
           of that country, then:

           32.1.1    any reference in this Agreement to, and any obligations
                     arising under this Agreement in, the currency of that
                     country shall be translated into, or paid in, the currency
                     unit of that country designated by the Bank acting
                     reasonably and in consultation with the Company; and

           32.1.2    any translation from one currency unit to another shall be
                     at the official rate of exchange recognised by the relevant
                     central bank for the conversion of that currency or
                     currency unit into the other, rounded up or down by the
                     Bank acting reasonably.

32.2       If a change in any currency of a country occurs, the Bank and the
           Company will negotiate in good faith in order to agree any amendments
           to this Agreement to reflect market practice at that time with regard
           to the occurrence of EMU within the European Union or any part(s) of
           it and the new currency and to put the Bank and the Borrowers in the
           same position, so far as is possible, that they would have been in if
           no change in currency had occurred.

32.3       The Bank and the Company agree that the occurrence or non-occurrence
           of EMU within the European Union or part(s) of it and/or any event or
           events associated with EMU and/or the introduction of any new
           currency in all or any part of the European Union will not result in
           the discharge cancellation, rescission or termination in whole or in
           pat of this Agreement or give any party hereto the right to cancel,
           rescind, terminate or vary (other than as aforesaid) this Agreement
           in whole or in part or give rise to an Event of Default.

33.        COUNTERPARTS

           This Agreement may be executed in any number of counterparts each of
           which shall be an original and all of such counterparts taken
           together shall be delivered to constitute one and the same
           instrument.

34.        APPLICABLE LAW AND JURISDICTION

34.1       The law of England and Wales is the law applicable to this Agreement.

34.2       Each of the Borrowers irrevocably agrees for the benefit of the Bank
           that the courts of England shall have jurisdiction to hear and
           determine any suit, action or proceeding, and to settle any disputes,
           which may arise out of or in connection with this Agreement and, for
           such purposes, irrevocably submits to the jurisdiction of such
           courts.

34.3       Each of the Borrowers which is not incorporated in England and Wales
           agrees that the process by which any suit, action or proceeding is
           begun in England and Wales may be served on it by being delivered to
           the Company at its registered office for the time being and hereby
           appoints the Company (and the Company accepts such appointment) for
           such purposes. If the appointment of the person mentioned in this
           Clause 34.3 ceases to be effective in respect of any or all of the
           Borrowers such Borrower or Borrowers shall immediately appoint a
           further person in England and Wales to accept service of process on
           its behalf in England and Wales and, failing such appointment within
           fifteen days, the Bank acting reasonably shall be entitled to appoint
           such a person by notice to such Borrower or Borrowers. Nothing
           contained herein shall affect the right to serve process in any other
           manner permitted by law.

34.4       Each of the Borrowers irrevocably waives any objection which it might
           now or hereafter have to the courts referred to in Clause 34.2 being
           nominated as the forum to hear and determine any suit, action or
           proceeding, and to settle any disputes, which may arise out of or in
           connection with this Agreement and agrees not to claim that any such
           court is not a convenient or appropriate forum.

34.5       The submission to the jurisdiction of the courts referred to in
           Clause 34.2 shall not (and shall not be construed so as to) limit the
           right of the Bank to take proceedings against any of the Borrowers in
           any other court of competent jurisdiction nor shall the taking of
           proceedings in any one or more jurisdictions preclude the taking of
           proceedings in any other jurisdiction (whether concurrently or not)
           if and to the extent permitted by applicable law.

This Agreement has been entered into on the date stated at the beginning of this
Agreement.

                     (b)        no Default is outstanding or might result from
                                the Utilisation; and

           4.2.2     the Utilisation would not cause Clause 2.2 (Overall
                     facility limit) to be contravened.

           4.2.3     in the case of the first Utilisation either:

                     (a)        the total aggregate amounts outstanding under
                                the Revolving Multi-Currency Credit Facility
                                Agreement dated 14th May 1993 (as amended)
                                between the Company and the Bank, the "Existing
                                Outstandings", shall have been repaid or prepaid
                                in full and the aggregate commitments under such
                                facility agreement cancelled on the day of such
                                repayment or prepayment; or

                     (b)        the amount of the first Utilisation together
                                with other sums available to the Borrower shall
                                be used to repay or prepay the Existing
                                Outstandings and the aggregate commitments under
                                such facility agreement cancelled on the day of
                                such repayment or prepayment.

5.         THE FACILITY

           THE LOAN FACILITY

           RECEIPT OF REQUESTS FOR ADVANCES

5.1        Any Borrower may utilise the Facility if the Bank receives, not later
           than 10.00 a.m. on the Rate Fixing Day a duly completed Request,
           substantially in the form of Schedule 3 and signed by an Authorised

           delivery by the relevant Borrower to the Bank of a duly completed
           Request to be actually received by the Bank not later than the close
           of business in London on the day on which such telephone notice is,
           or is deemed to have been, given.

                     (b)        if the currency is Dollars, a minimum of US
                                $1,000,000 and an integral multiple of US
                                $100,000; or

                     (c)        if the currency is an Optional Currency other
                                than Dollars, a minimum and integral multiple of
                                the amounts agreed between the relevant Borrower
                                and the Bank before the telephone notice of
                                Utilisation or delivery of that Request; or

                     (d)        such other amounts as the Bank and the relevant
                                Borrower may agree;

           5.3.3     only one Term is specified which:

                     (a)        does not overrun the Final Maturity Date; and

                     (b)        is a period of an approved duration or of an
                                optional duration; and

           5.3.4     the payment instructions comply with Clause 9 (Payments).

           In this Clause:

           "APPROVED DURATION" means a period of 1, 2, 3 or 6 months; and

           "OPTIONAL DURATION" means any other period not exceeding 12 months.

           SELECTION OF TERM OF OPTIONAL DURATION

5.4        If the relevant Borrower selects a Term of an optional duration, it
           may also select at the time of the telephone notice of Utilisation
           and in the relevant Request a Term of any approved duration to apply
           if the selection of a Term of an optional duration becomes
           ineffective in accordance with Clause 5.5.2.

5.5        If:

           5.5.1     the relevant Borrower requests a Term of an optional
                     duration; and

           5.5.2     the Bank notifies such Borrower not later than 10.30 a.m.
                     on the date of receipt by it of the relevant Request or
                     telephone notice of Utilisation pursuant to Clause 5.1 or
                     Clause 5.2 respectively that it does not agree to that
                     request,

           the Term for the proposed Utilisation shall be the alternative period
           specified in the telephone notice of Utilisation or the relevant
           Request or, in the absence of any alternative selection, 3 months.

           PAYMENT OF PROCEEDS

5.6        Subject to the terms of this Agreement, the Bank shall make the
           Advance available to the relevant Borrower on the relevant
           Utilisation Date.

           AUTOMATIC CANCELLATION OF THE COMMITMENT

6.1        The Commitment shall be automatically cancelled at close of business
           on the Final Maturity Date.

           VOLUNTARY CANCELLATION

6.2        The Company may, without penalty and by giving not less than 15 days'
           prior notice to the Bank, cancel the Commitment in whole or in part.

6.3        A notice of cancellation will be irrevocable and shall specify:

           6.3.1     the date on which the cancellation is to become effective;
                     and

           6.3.2     the amount of the Commitment to be cancelled.

6.4        Any cancellation may only take effect in respect of the unutilised
           portion of the Commitment as at the date the notice is to be
           effective.

           NO REINSTATEMENT

6.5        No amount of the Commitment cancelled under this Agreement may
           subsequently be reinstated.

7.         INTEREST

           INTEREST RATE

7.1        The rate of interest on each Advance for its Term is the rate per
           annum determined by the Bank to be the aggregate of the applicable:

           7.1.1     Margin,

           7.1.2     LIBOR; and

           7.1.3     Mandatory Costs.

           DUE DATES

7.2        Except as otherwise provided in this Agreement, accrued interest on
           each Advance is payable on its Maturity Date and also, in the case of
           an Advance with a term longer than six months, on the date falling
           six months after its Utilisation Date.

           DEFAULT INTEREST

7.3        If any Borrower fails to pay any amount payable by it under this
           Agreement, it shall, on demand by the Bank from time to time, pay
           interest on the overdue amount from the due date up to the date of
           actual payment, after as well as before judgment, at a rate (the
           "DEFAULT RATE") determined by the Bank to be one (1) per cent. per
           annum above the higher of:

           7.3.1     the rate on the overdue amount under Clause 7.1 (Interest
                     rate) immediately before the due date (but only if the
                     overdue amount is an Advance (or part thereof) and only for
                     the period up to and including the Maturity Date of that
                     Advance); and

           7.3.2     the rate which would have been payable if the overdue
                     amount had, during the period of non-payment, constituted
                     an Advance in the currency of the overdue amount for such
                     successive Terms of such duration (not exceeding three
                     months) as the Bank may reasonably determine (each a
                     "DESIGNATED TERM").

7.4        The default rate will be determined on the first day of, or two
           Business Days before the first day of, the relevant Designated Term,
           as appropriate.

7.5        If the Bank determines that deposits in the currency of the overdue
           amount are not at the relevant time being made available by leading
           banks in the London Interbank Market, the default rate will be
           determined by reference to the cost of funds to the Bank from
           whatever sources it may reasonably select.

7.6        Default interest shall be compounded at the end of each Designated
           Term until it is paid.

           NOTIFICATION OF RATES OF INTEREST

7.7        The Bank shall promptly notify the relevant Borrower of the
           determination of any applicable rate of interest under this
           Agreement.

8.         REPAYMENT AND PREPAYMENT

           REPAYMENT OF ADVANCES

8.1        Each Borrower shall repay each Advance made to it in full on its
           Maturity Date to the Bank. If an Advance (the "NEW ADVANCE") is to be
           made to a Borrower on the day on which another Advance (the "MATURING
           ADVANCE") in the same currency is due to be repaid by such Borrower
           then, subject to the terms of this Agreement and so long as the
           conditions referred to in Clause 4.2 shall have been satisfied in
           relation to the New Advance:

           8.1.1     the Maturing Advance shall be deemed to have been repaid on
                     its Maturity Date either in whole (if the New Advance is
                     equal to or greater than the Maturing Advance) or in part
                     (if the New Advance is less than the Maturing Advance); and



                                      -13-
<PAGE>   14

           8.1.2     to the extent that a Maturing Advance is so deemed to have
                     been repaid, the principal amount of the New Advance to be
                     made on such a date shall be deemed to have been credited
                     to the account of such Borrower by the Bank in accordance
                     with the terms of this Agreement and, as the case may be:

                     (a)        the Bank shall only be obliged to make available
                                to such Borrower pursuant to Clause 5.6 a
                                principal amount equal to the amount (if any) by
                                which the New Advance exceeds the Maturing
                                Advance; or

                     (b)        such Borrower shall only be obliged to pay to
                                the Bank pursuant to this Clause 8.1 a principal
                                amount equal to the amount by which the Maturing
                                Advance exceeds the New Advance.

8.2        On the Final Maturity Date, all outstanding Advances and other sums
           (if any) then owing under this Agreement shall in any event be repaid
           or paid in full.

           PREPAYMENT OF ADVANCES

8.3        Any Borrower may, without penalty and on giving not less than 15
           days' prior notice to the Bank, prepay all or any part of an Advance,
           but if in part, in a minimum amount of Pound Sterling 1,000,000 and
           an integral multiple of Pound Sterling 100,000 (or the comparable
           amount in any Optional Currency).

8.4        Any notice by a Borrower of prepayment under this Agreement is
           irrevocable.

8.5        Should any person or group of persons, acting either individually or
           in concert (as defined in the City Code on Take Overs and Mergers
           effective as at the date of this Agreement) otherwise than with the
           consent of the Bank acquire control of the Company (and for the
           purpose of this Clause a single person or group of persons shall have
           acquired control if it or they own or hold more than 50% (fifty per
           cent.) of the issued share capital of the Company having the right to
           attend and vote at general meetings of the Company or more than 50%
           (fifty per cent.) of such rights), then:

           8.5.1     the Company shall immediately upon becoming aware thereof
                     notify the Bank specifying the date of such acquisition and
                     the name of such person or persons acquiring control; and

           8.5.2     thereafter no Borrower shall be permitted to request an
                     Advance unless the terms of the acquisition of control of
                     the Company were approved by the Board of Directors of the
                     Company and the Maturity Date for any Advance requested
                     falls on a date not more than three months after the
                     expiration of the 30 day period referred to in Clause 8.6.

8.6        If the terms of the acquisition of control of the Company were
           approved by the Board of Directors of the Company, the Bank shall
           consult with the Company during the period of 30 days after receipt
           of the notification from the Company referred to in sub-Clause 8.5.1
           and shall be entitled to give notice of



                                      -14-
<PAGE>   15

           continuance of the Facility provided hereunder to the Company. Upon
           receipt of such notice of continuance, the right of the Borrowers to
           request an Advance without the limitation referred to in sub-Clause
           8.5.2 shall be reinstated.

8.7        If the terms of the acquisition of control of the Company were
           approved by the Board of Directors of the Company but, at the end of
           the period of 30 days referred to in Clause 8.6 above, the Company
           has not received a notice of continuance then:

           8.7.1     the Facility shall be cancelled;

           8.7.2     any outstanding Advances with Maturity Dates falling later
                     than three months after the end of such period shall be
                     prepaid on the date falling three months after the end of
                     such period, together with accrued interest thereon up to
                     the date of payment and all other amounts payable to the
                     Bank hereunder; and

           8.7.3     any outstanding Advances with Maturity Dates falling not
                     later than three months after the end of such period shall
                     be repaid on their respective Maturity Dates.

8.8        If the terms of the acquisition of control of the Company were not
           approved by the Board of Directors of the Company, then unless the
           Bank shall have confirmed within 2 days of receipt of the notice
           referred to in sub-Clause 8.5.1 that the Facility shall be continued,
           the Facility shall be cancelled and any outstanding Advances shall be
           repayable on demand by the Bank together with accrued interest
           thereon up to the date of payment and all other amounts payable to
           the Bank hereunder.

8.9        Any prepayment under this Agreement shall be made together with
           accrued interest on the amount prepaid together with any amount
           payable to the Bank pursuant to Clause 22.3.

8.10       No Advance may be prepaid otherwise than in accordance with the
           express terms of this Agreement.

           the other or to such other place as may be agreed between the parties
           for this purpose.

                     place for payment on the due date in lawful money of the
                     country of that Optional Currency, in immediately available
                     funds, or at such times or in such funds as the Bank may
                     specify to the relevant Borrower as being customary at the
                     time for the settlement of transactions in the relevant
                     currency in the place for payment.

           Advance requested to be denominated in the currency of a
           Participating Member State shall be made in the euro unit.

9.7        If and to the extent that any EMU legislation provides that an amount
           denominated either in the euro unit or in the national currency unit
           of a given Participating Member State and payable within that
           Participating Member State by crediting an account of the creditor,

           currency unit, a Party shall be entitled to pay that amount either in
           the euro unit or in the relevant national currency unit.

           SET-OFF AND COUNTERCLAIM

9.8        All payments made by each of the Borrowers under this Agreement shall
           be made without set-off or counterclaim.

           NON-BUSINESS DAYS

9.9        If a payment under this Agreement is due on a day which is not a
           Business Day, then the due date for the payment shall instead be the
           next Business Day.

9.10       During any extension of the due date for payment of any principal
           under this Agreement pursuant to Clause 9.9 above interest is payable
           on the principal at the rate payable on the original due date.

           PARTIAL PAYMENTS

9.11       If the Bank receives a payment insufficient to discharge all the
           amounts then due and payable by any Borrower under this Agreement,
           the Bank shall apply that payment towards the obligations of such
           Borrower under this Agreement in the following order:


                                      -16-
<PAGE>   17


           9.11.1    firstly, in or towards payment of any unpaid costs and
                     expenses of the Bank under this Agreement;

           9.11.2    secondly, in or towards payment of any accrued fees due but
                     unpaid under Clause 19.2 (Commitment Fee);

           9.11.3    thirdly, in or towards payment of any accrued interest due
                     but unpaid under this Agreement;

           9.11.4    fourthly, in or towards payment of any principal due but
                     unpaid under this Agreement, and

           9.11.5    fifthly, in or towards payment of any other sum due but
                     unpaid under this Agreement.

9.12       The Bank may vary the order set out in Clauses 9.11.1 to 9.11.5
           above.

9.13       Clauses 9.11 and 9.12 above shall override any appropriation made by
           any Borrower.

10.        OPTIONAL CURRENCIES

           SELECTION

10.1       No Borrower may request an Advance denominated in an Optional
           Currency unless the Bank has confirmed to such Borrower that the
           Optional Currency is readily available and freely transferable in the
           London foreign exchange market.

           CHANGE OF CURRENCY

10.2       If, on the Rate Fixing Day of an Advance to be denominated in an
           Optional Currency, the Bank determines that:

           10.2.1    it is impracticable for reasons beyond its control for the
                     Bank to fund the Advance for its Term in that Optional
                     Currency in the ordinary course of business in the London
                     Interbank Market; or

           10.2.2    the use of the proposed Optional Currency might contravene
                     any law or regulation,

           then:

           10.2.3    the Bank shall promptly and in any event before 10.30 a.m.
                     on that Rate Fixing Day notify the relevant Borrower;

           10.2.4    if the Bank receives notice from the relevant Borrower by
                     11.30 a.m. on that Rate Fixing Day to that effect, the
                     Advance will not be made; and

           10.2.5    if the Bank does not receive any notice under sub-Clause
                     10.2.4 above, the Advance will be denominated instead in
                     Sterling in an amount equal to its Original Sterling
                     Amount.



                                      -17-
<PAGE>   18

           NOTIFICATION OF RATES AND AMOUNTS

10.3       The Bank shall, on request, promptly notify the relevant Borrower of
           any applicable Bank's Spot Rate of Exchange or Original Sterling
           Amount promptly after it has been ascertained.

10.4       If an Advance which has been drawn in an Optional Currency is
           reborrowed in the same Optional Currency immediately following its
           repayment, then the Original Sterling Amount of such new Advance
           denominated in such Optional Currency shall be recalculated for the
           new Term in accordance with the terms and conditions of this
           Agreement and if on the relevant Utilisation Date the aggregate
           Original Sterling Amount of all Advances outstanding on such date
           exceeds the Commitment, then any excess shall be repaid to the Bank
           by the relevant Borrower upon the Bank's first written demand.

11.        TAXES

           GROSS-UP

11.1       All payments by each of the Borrowers under this Agreement shall be
           made without any deductions and free and clear of and without
           deduction for or on account of any Relevant Taxes except to the
           extent that any Borrower is required by law to make payment subject
           to any such taxes. If any Relevant Tax or amounts in respect of any
           Relevant Tax must be deducted from any amounts payable or paid by any
           Borrower hereunder, such Borrower shall pay such additional amounts
           as may be necessary to ensure that the Bank receives a net amount
           equal to the full amount which it would have received had payment not
           been made subject to tax.

           "RELEVANT TAX" in relation to any payment which falls to be made
           hereunder means any present or future taxes of any nature now or
           hereafter imposed by the laws of (i) the United Kingdom, (ii) any
           other jurisdiction from which, or through which, such payment is made
           or to the taxation laws of which the relevant Borrower is at the time
           of such payment subject, (iii) any political sub-division of the
           United Kingdom or any such other jurisdiction or (iv) any federation
           or association of states of which the United Kingdom or any such
           other jurisdiction is, at the time of such payment, a member.

           TAX RECEIPTS

11.2       All Relevant Taxes required by law to be deducted or withheld by any
           Borrower from any amount paid or payable under this Agreement shall
           be paid by such Borrower when due (unless the obligation to pay is
           being disputed in good faith) and such Borrower shall, within 30 days
           of the payment being made, deliver to the Bank evidence satisfactory
           to the Bank (including all relevant tax receipts) that the payment
           has been duly remitted to the appropriate authority.

           TAX CREDITS

11.3       If any Borrower pays any additional amount (a "TAX PAYMENT") under
           Clause 11.1 and the Bank effectively obtains a refund of tax, or a
           relief or credit against



                                      -18-
<PAGE>   19

           tax by reason of that Tax Payment (a "TAX CREDIT"), and the Bank is
           able to identify the Tax Credit as being attributable to the Tax
           Payment, then the Bank shall reimburse to the relevant Borrower such
           amount as the Bank reasonably determines to be the proportion of the
           Tax Credit as will leave the Bank (after that reimbursement) in no
           better or worse position that it would have been if the Tax Payment
           had not been required. Nothing in this Clause interferes with the
           right of the Bank to arrange its tax affairs in whatever manner it
           thinks fit and, without prejudice to the foregoing, the Bank is under
           no obligation to claim a Tax Credit, or to claim a Tax Credit in
           priority to any other claim, relief, credit or deduction available to
           it. The Bank is not obliged to disclose any information regarding its
           tax affairs or computations to any Borrower.

           QUALIFYING BANK

11.4       If, otherwise than as a result of the introduction of, change in, or
           change in the interpretation, administration or application of, any
           law or regulation or any practice or concession of the Inland Revenue
           after the Signing Date, the Bank ceases to be a Qualifying Bank no
           Borrower shall be liable to pay to the Bank under Clause 11.1
           (Gross-up) any amount in respect of taxes levied or imposed by the UK
           or any taxing authority thereof or therein in excess of the amount it
           would have been obliged to pay if the Bank had been or had not ceased
           to be a Qualifying Bank.

12.        MARKET DISRUPTION

           MARKET DISRUPTION

12.1       If, in relation to any proposed Utilisation:

           12.1.1    the Bank is unable to obtain from leading banks a rate for
                     the purposes of determining the applicable LIBOR or the
                     Bank otherwise determines that adequate and fair means do
                     not exist for ascertaining the applicable LIBOR; or

           12.1.2    in the opinion of the Bank:

                     (a)        matching deposits may not be available to it in
                                the London Interbank Market in the ordinary
                                course of business to fund an Advance; or

                     (b)        the cost to it of matching deposits in the
                                London Interbank Market would be in excess of
                                the relevant LIBOR,

                     the Bank shall notify the Company by 10.30 a.m. or as soon
                     as is practicable thereafter on the Rate Fixing Day of the
                     fact and that this Clause is in operation.

12.2       After any notification under Clause 12.1 above:

           12.2.1    subject to sub-Clause 12.2.3 below the relevant Advance
                     shall be made in Sterling in an amount equal to its
                     Original Sterling Amount (unless Sterling was the original
                     currency of the relevant Advance);


                                      -19-
<PAGE>   20

           12.2.2    subject to sub-Clause 12.2.3 below, no further notices of
                     Utilisation by telephone or Requests for Advances to be
                     denominated in the original currency of the affected
                     Advance may be delivered until the Bank notifies the
                     Company that the event specified in the notification no
                     longer prevails;

           12.2.     the relevant Borrower may, by notice to the Bank by 11.00
                     a.m. (or, if later, within 30 minutes of receipt by the
                     Company of a notification under sub-Clause 12.1.2) on the
                     Rate Fixing Day: (i) elect for the notice of Utilisation by
                     telephone or the Request to be cancelled without penalty;
                     (ii) if the Advance was to be made in an Optional Currency,
                     elect for the Advance to be made in an Optional Currency
                     other than a currency affected by the event specified in
                     the notification or (iii) elect for the Advance to be made
                     in accordance with the Request notwithstanding the event
                     specified in the notification. If any Borrower requires an
                     affected Advance to be made in the original currency
                     selected for such Advance notwithstanding the event
                     specified in the notification then within five Business
                     Days of receipt of the notification, the Company and the
                     Bank shall enter into negotiations for a period of not more
                     than 25 days with a view to agreeing a substitute basis for
                     determining the rate of interest and/or funding applicable
                     to the affected Advance and any future Advances in the
                     currency of the affected Advance provided that if no
                     substitute basis is agreed within that period:

                     (a)        the Bank shall certify to the Company (such
                                certificate to be conclusive) the alternative
                                interest rate calculated in accordance with
                                sub-Clause 12.2.4 below;

                     (b)        the certificate may make provision for different
                                funding periods and shall be retroactive to the
                                beginning of the then current Term; and

                     (c)        the certificate shall be binding on each
                                relevant Borrower unless the Company gives
                                notice to the Bank within five Business Days of
                                the receipt of the certificate that the
                                certificate is not acceptable and that each
                                relevant Borrower shall prepay in full the
                                relevant Advances on a Business Day specified in
                                the notice, which shall be not less than five
                                nor more than thirty days after the date of the
                                Bank's certificate to the Company; and

           12.2.4    for the purposes of sub-Clause 12.2.3(a) above the rate of
                     interest on each Advance shall be the rate certified by the
                     Bank as the rate per annum determined by the Bank to be the
                     aggregate of:

                     (a)        the Margin;

                     (b)        the rate notified by the Bank, on or before the
                                last day of its Term, as being the cost to the
                                Bank of funding the Advance from such other
                                sources as it may reasonably select; and


                                      -20-
<PAGE>   21

                     (c)        the applicable Mandatory Cost if any.

12.3       During the period when any substitute basis is in force in relation
           to a particular currency, the Bank shall periodically determine
           whether the circumstances referred to in Clause 12.1 above still
           apply and, if they do not, shall forthwith give notice in writing to
           the Company of the date on which the substitute basis will cease to
           apply.

13.        INCREASED COSTS

           INCREASED COSTS - SERVICE OF DEMAND

13.1       If the result of any introduction of or change in any law or
           regulation after the Signing Date, or of any change in the
           application or interpretation of any such changed law or regulation
           or compliance by the Bank with any such changed law or regulation
           after the Signing Date (including, without limitation, any law or
           regulation relating to taxation, any reserve, special deposit, cash
           ratio, liquidity or capital adequacy requirement or any form of
           banking or monetary control but excluding (i) changes arising from
           the implementation by any authority having jurisdiction over the Bank
           or its holding company of the matters set out in the statement
           prepared by the Basle Committee on Banking Regulations and
           Supervisory Practices dated July 1988 and entitled "International
           Convergence of Capital Measurement and Capital Standards" (as amended
           in November 1991) and (ii) changes arising from the implementation in
           whole or in part by any authority having jurisdiction over the Bank
           or its holding company of the proposals contained in the matters set
           out in the EC Directive 93/6/EEC of 15 March 1993 on the capital
           adequacy of investment firms and credit institutions) is that the
           Bank incurs an increased cost, then the Bank will promptly notify the
           Company of the relevant event and the Company shall on demand pay to
           the Bank such amount as the Bank certifies in the demand will
           compensate it for the applicable increased cost.

13.2       In this Clause 13 "INCREASED COST" means:

           13.2.1    an additional cost incurred by the Bank as a result of it
                     having entered into, or performing, maintaining or funding
                     its obligations under, this Agreement; or

           13.2.2    that portion of an additional cost incurred by the Bank in
                     making, funding or maintaining all or any advances
                     comprised in a class of advances formed by or including the
                     Advances made or to be made by it under this Agreement as
                     is attributable to it making, funding, or maintaining such
                     advances; or

           13.2.3    a reduction in any amount payable to the Bank or the
                     effective return to the Bank under this Agreement or on its
                     capital; or

           13.2.4    any payment made or interest or other return on or
                     calculated by reference to any amount received or
                     receivable by the Bank under this Agreement which is
                     forgone.


                                      -21-
<PAGE>   22

13.3       When calculating an increased cost, the Bank may allocate or spread
           costs, liabilities and losses to or across its liabilities or assets,
           or any class of liabilities or assets, and on such basis, as it
           reasonably considers appropriate.

           INCREASED COSTS - EXCEPTIONS

13.4       An increased cost does not include any increased cost:

           13.4.1    compensated for by the payment of the Mandatory Cost;

           13.4.2    compensated for by the operation of Clause 11 (Taxes);

           13.4.3    attributable to any change in the rate of tax on the
                     overall net income of the Bank (or the overall net income
                     of a division or branch of the Bank) imposed in the
                     jurisdiction in which its principal office or the relevant
                     lending office for the time being is situate;

           13.4.4    payable to an assignee or transferee of the Bank at the
                     time of an assignment, transfer or novation under Clause 25
                     (Changes to the Parties), but only to the extent that the
                     increased cost would not have been payable to the
                     assigning, transferring or novating Bank; or

           13.4.5    which is attributable to the introduction of the euro other
                     than an increased cost which is being incurred generally by
                     banks transacting euro business in the London interbank
                     market.

14.        ILLEGALITY

14.1       If it is or becomes unlawful for the Bank to give effect to any of
           its obligations as contemplated by this Agreement or to fund or
           maintain any Advance, then the Bank shall notify the Company
           accordingly and on the Maturity Date of each relevant Advance (or
           such earlier date as the relevant law or directive may require) the
           relevant Borrower shall repay or prepay, as the case may be, any

           payable by it to the Bank under this Agreement.

           PREPAYMENT AND CANCELLATIONS

15.1       If any Borrower is required to pay any additional amounts to the Bank
           under Clause 11 (Taxes) or compensation under Clause 13 (Increased
           Costs), the Company may, whilst the circumstances giving rise to the
           requirement continue, serve a notice of prepayment and cancellation
           in relation to all or all affected Advances on the Bank.

15.2       On the tenth Business Day after the date of service of the notice the

           Bank together with all other amounts in relation to such Advance(s)

           shall be cancelled on the date of service of the notice.

           MITIGATION

15.4       If, in respect of the Bank, circumstances arise which would or would,
           with the giving of notice, result in:

           15.4.1    any additional amounts becoming payable under Clause 11
                     (Taxes); or

           15.4.2    any increased cost becoming payable under Clause 13
                     (Increased Costs); or

           15.4.3    any prepayment, payment or cancellation under Clause 14
                     (Illegality),

           then the Bank shall endeavour to take such steps as are reasonably
           open to it to mitigate or remove those circumstances (including
           seeking recovery for the account of the relevant Borrower where
           reasonably practicable and/or transferring its rights and obligations
           under this Agreement to another bank or financial institution
           acceptable to the Company).

15.5       Clause 15.4 above does not:

           15.5.1    prejudice the obligations of any Borrower under this
                     Agreement (including, without limitation, under the Clauses
                     referred to in Clause 15.4 above); or

           15.5.2    require the Bank to take any action which, in its opinion,

           EVENTS OF DEFAULT

18.1       Each of the events set out in Clauses 18.2 to 18.13 (inclusive) is an
           Event of Default (whether or not caused by any reason whatsoever
           outside the control of the relevant Borrower or any other person),
           except that if any of the events specified in Clauses 18.6 to 18.13
           (inclusive) occurs in relation to a Material Subsidiary which is not
           a Borrower it will only be an Event of Default if the event is, in
           the reasonable opinion of the Bank, reasonably likely to affect
           materially and adversely the Company's ability to perform its
           obligations under this Agreement.

           NON-PAYMENT

18.2       Any Borrower defaults in payment on the due date of any amount

           to the Company and the relevant Borrower of the default.

           BREACH OF OTHER OBLIGATIONS

18.3       Any Borrower fails to observe or perform any other obligation on its
           part contained in this Agreement (other than those which, in the
           reasonable opinion of the Bank, are not material), and (in the case
           of a breach capable of being remedied) fails to remedy the breach
           within fourteen Business Days after the date on which the Company and
           the relevant Borrower receive notice of the breach from the Bank.

           MISREPRESENTATION

18.4       A representation, warranty or statement made or repeated in, this
           Agreement by any Borrower proves to have been untrue in any material
           particular when made or deemed to be repeated.

           in circumstances where the aggregate amount of such Borrowings
           exceeds Pound Sterling 10,000,000 (or its equivalent in other
           currencies).

           INSOLVENCY

18.6       Any Borrower or Material Subsidiary is, or is deemed for the purposes
           of any law to be, unable to pay its debts generally as they fall due

           they fall due; or

18.7       Any Borrower or Material Subsidiary suspends making payments on all
           or any class of its debts or announces an intention to do so, or a

           the Bank under Clause 18.8) ceases, or threatens to cease, to carry
           on all, or substantially all, of its business.

           ACCELERATION

18.14      On and at any time after the occurrence of an Event of Default the

31.        DESIGNATION OF ACCEDING AND SECEDING BORROWERS

31.1       The Company may request that any of its Subsidiaries incorporated in
           England and Wales and, with the prior written consent of the Bank
           (such consent not to be unreasonably withheld or delayed) any other
           Subsidiary of the Company becomes an Acceding Borrower by delivering
           or procuring the delivery to the Bank a Borrower's Accession Notice
           duly executed by the Company and the relevant Subsidiary provided
           that if such Subsidiary is not resident in the United Kingdom for tax
           purposes the Company and the Bank agree to make such amendments to
           this Agreement as may be reasonably required at the time in order to
           allow such Subsidiary to pay interest to the Bank without deduction
           or withholding of any Relevant Tax and to provide such Subsidiary
           with equivalent rights, mutatis mutandis, to those contained in
           Clause 11.4 (Qualifying Bank).

31.2       Upon delivery of a Borrower's Accession Notice, the relevant
           Subsidiary shall become an Acceding Borrower and shall, subject to
           the terms and conditions of this Agreement acquire all the rights and
           assume all the obligations of a Borrower hereunder provided that the
           Bank has confirmed to the Company that it has received, in form and
           substance satisfactory to it, all the documents set out in Part II of
           Schedule 1.

31.3       The Company undertakes that it shall procure that each Acceding
           Borrower shall provide the Bank with each of the documents listed in
           Part II of Schedule 1.

31.4       If at any time any Borrower (other than the Company) has no actual or
           contingent obligation under this Agreement, the Company may deliver a
           Borrower's Cessation Notice to the Bank in which event such Borrower
           shall forthwith cease to be a Borrower upon receipt by the Bank of
           such notice.

32.        CHANGE OF CURRENCY

32.1       If more than one currency or currency unit are at the same time
           recognised by the central bank of any country as the lawful currency
           of that country, then:

           32.1.1    any reference in this Agreement to, and any obligations
                     arising under this Agreement in, the currency of that
                     country shall be translated into, or paid in, the currency
                     unit of that country designated by the Bank acting
                     reasonably and in consultation with the Company; and

           32.1.2    any translation from one currency unit to another shall be
                     at the official rate of exchange recognised by the relevant
                     central bank for the conversion of that currency or
                     currency unit into the other, rounded up or down by the
                     Bank acting reasonably.

32.2       If a change in any currency of a country occurs, the Bank and the
           Company will negotiate in good faith in order to agree any amendments
           to this Agreement to reflect market practice at that time with regard
           to the occurrence of EMU within the European Union or any part(s) of
           it and the new currency and to put the Bank and the Borrowers in the
           same position, so far as is possible, that they would have been in if
           no change in currency had occurred.

<PAGE>   39

32.3       The Bank and the Company agree that the occurrence or non-occurrence
           of EMU within the European Union or part(s) of it and/or any event or
           events associated with EMU and/or the introduction of any new
           currency in all or any part of the European Union will not result in
           the discharge cancellation, rescission or termination in whole or in
           pat of this Agreement or give any party hereto the right to cancel,
           rescind, terminate or vary (other than as aforesaid) this Agreement
           in whole or in part or give rise to an Event of Default.

33.        COUNTERPARTS

           This Agreement may be executed in any number of counterparts each of
           which shall be an original and all of such counterparts taken
           together shall be delivered to constitute one and the same
           instrument.

34.        APPLICABLE LAW AND JURISDICTION

34.1       The law of England and Wales is the law applicable to this Agreement.

34.2       Each of the Borrowers irrevocably agrees for the benefit of the Bank
           that the courts of England shall have jurisdiction to hear and
           determine any suit, action or proceeding, and to settle any
           disputes, which may arise out of or in connection with this
           Agreement and, for such purposes, irrevocably submits to the
           jurisdiction of such courts.

34.3       Each of the Borrowers which is not incorporated in England and Wales
           agrees that the process by which any suit, action or proceeding is
           begun in England and Wales may be served on it by being delivered to
           the Company at its registered office for the time being and hereby
           appoints the Company (and the Company accepts such appointment) for
           such purposes. If the appointment of the person mentioned in this
           Clause 34.3 ceases to be effective in respect of any or all of the
           Borrowers such Borrower or Borrowers shall immediately appoint a
           further person in England and Wales to accept service of process on
           its behalf in England and Wales and, failing such appointment within
           fifteen days, the Bank acting reasonably shall be entitled to appoint
           such a person by notice to such Borrower or Borrowers. Nothing
           contained herein shall affect the right to serve process in any other
           manner permitted by law.

34.4       Each of the Borrowers irrevocably waives any objection which it might
           now or hereafter have to the courts referred to in Clause 34.2 being
           nominated as the forum to hear and determine any suit, action or
           proceeding, and to settle any disputes, which may arise out of or in
           connection with this Agreement and agrees not to claim that any such
           court is not a convenient or appropriate forum.

34.5       The submission to the jurisdiction of the courts referred to in
           Clause 34.2 shall not (and shall not be construed so as to) limit the
           right of the Bank to take proceedings against any of the Borrowers in
           any other court of competent jurisdiction nor shall the taking of
           proceedings in any one or more jurisdictions preclude the taking of
           proceedings in any other jurisdiction (whether concurrently or not)
           if and to the extent permitted by applicable law.

           4.2.2     the Utilisation would not cause Clause 2.2 (Overall
                     facility limit) to be contravened.

           4.2.3     in the case of the first Utilisation either:

                     (a)        the total aggregate amounts outstanding under
                                the Revolving Multi-Currency Credit Facility
                                Agreement dated 14th May 1993 (as amended) made
                                between the Company and the Bank the "Existing
                                Outstandings", shall have been repaid or prepaid
                                in full and the aggregate commitments under such
                                facility agreements cancelled on the day of such
                                repayment or prepayment; or

                     (b)        the amount of the first Utilisation together
                                with other sums available to the Borrower shall
                                be used to repay or prepay the Existing
                                Outstandings and the aggregate commitments under
                                such facility agreement cancelled on the day of
                                such repayment or prepayment.

5.         THE FACILITIES

           THE REVOLVING FACILITY

           RECEIPT OF REQUESTS FOR REVOLVING ADVANCES

5.1        Any Borrower may utilise the Revolving Facility if the Bank receives,
           not later than 10.00 a.m. on the Rate Fixing Day a duly completed
           Request, substantially in the form of Schedule 3 and signed by an
           Authorised Signatory of the relevant Borrower.

5.2        Any Borrower may utilise the Revolving Facility by notifying the Bank
           by telephone not later than 10.00 a.m. on the Rate Fixing Day
           provided that a notice given by telephone shall be confirmed in
           writing by the delivery by the relevant Borrower to the Bank of a
           duly completed Request to be actually received by the Bank not later
           than the close of business in London on the day on which such
           telephone notice is, or is deemed to have been, given.

           COMPLETION OF REQUESTS FOR REVOLVING ADVANCES

5.3        When giving a notice of Utilisation by telephone and when completing
           the Request, the relevant Borrower must ensure that:

           5.3.1     the Utilisation Date is a Business Day;

           5.3.2     only one currency is specified and that the Requested
                     Amount is:

                     (a)        if the currency is Sterling, a minimum
                                of Pound Sterling 1,000,000 and an integral
                                multiple of Pound Sterling 100,000; or

                     (b)        if the currency is Dollars, a minimum of US
                                $1,000,000 and an integral multiple of US
                                $100,000; or

                     (c)        if the currency is an Optional Currency other
                                than Dollars, a minimum and integral multiple of
                                the amounts agreed


                                      -11-
<PAGE>   12


                                between the relevant Borrower and the Bank
                                before the telephone notice of Utilisation or
                                delivery of that Request; or

                     (d)        such other amounts as the Bank and the relevant
                                Borrower may agree;

           5.3.3     only one Term is specified which:

                     (a)        does not overrun the Availability Period End
                                Date; and

                     (b)        is a period of an approved duration or of an
                                optional duration; and

           5.3.4     the payment instructions comply with Clause 9 (Payments).

           In this Clause:

           "APPROVED DURATION" means a period of 1, 2, 3 or 6 months; and

           "OPTIONAL DURATION" means any other period not exceeding 12 months.

           SELECTION OF TERM OF OPTIONAL DURATION

5.4        If the relevant Borrower selects a Term of an optional duration, it
           may also select at the time of the telephone notice of Utilisation
           and in the relevant Request a Term of any approved duration to apply
           if the selection of a Term of an optional duration becomes
           ineffective in accordance with Clause 5.5.2.

5.5        If:

           5.5.1     the relevant Borrower requests a Term of an optional
                     duration; and

           5.5.2     the Bank notifies such Borrower not later than 10.30 a.m.
                     on the date of receipt by it of the relevant Request or
                     telephone notice of Utilisation pursuant to Clause 5.1 or
                     Clause 5.2 respectively that it does not agree to that
                     request,

           the Term for the proposed Utilisation shall be the alternative period
           specified in the telephone notice of Utilisation or the relevant
           Request or, in the absence of any alternative selection, 3 months.

           PAYMENT OF PROCEEDS

5.6        Subject to the terms of this Agreement, the Bank shall make the
           Revolving Advance available to the relevant Borrower on the relevant
           Utilisation Date.

           THE TERM-OUT FACILITY

           EXERCISE OF THE TERM-OUT OPTION

5.7        5.7.1     The Company may at any time during the Availability Period,
                     by a notice (a "Conversion Notice") given to the Bank:


                                      -12-

<PAGE>   13

                     (a)        prior to 10.00 a.m. on the last day of the Term
                                of any Revolving Advance to be converted into a
                                Term Advance denominated in Sterling; or

                     (b)        prior to 10.00 a.m. on the second Business Day
                                before the last day of the Term of any Revolving
                                Advance to be converted into a Term Advance
                                denominated in an Optional Currency,

                     convert such Revolving Advance into a Term Advance. Any
                     such notice shall be in writing, shall be irrevocable, and
                     shall specify (i) the Revolving Advance to be converted
                     into a Term Advance, (ii) the date on which the Conversion
                     Notice is to take effect in respect of such Revolving
                     Advance (the "Conversion Date") which shall be the last day
                     of the Term relative thereto, and (iii) the Interest Period
                     to be applicable to such Term Advance. The Company may in
                     the Conversion Notice require such Term Advance to be
                     denominated in a currency (the "New Currency") other than
                     the currency of the Revolving Advance (the "Original
                     Currency") and in such case (i) the New Currency shall be
                     Sterling or an Optional Currency that the Bank confirms is
                     freely available to it on the applicable Conversion Date;
                     (ii) the principal amount of such Term Advance shall be the
                     Original Sterling Amount of the Revolving Advance where the
                     New Currency is Sterling or the amount of the New Currency
                     that the Bank determines on the applicable Rate Fixing Day
                     may be then purchased at the Bank's Spot Rate of Exchange
                     with such Original Sterling Amount where the New Currency
                     is an Optional Currency.

           5.7.2     A Conversion Notice shall take effect as if it were a
                     Utilisation and accordingly the Bank shall only be obliged
                     to give effect to a Conversion Notice where the terms of
                     Clause 4.2 are satisfied.

           5.7.3     Each Term Advance shall have an Interest Period which shall
                     be of a duration of one, three or six months (or such other
                     period as may be agreed by the Bank) as selected by the
                     relevant Borrower by notice to be received by the Bank not
                     later than 10.00 a.m. (London time) on the Rate Fixing Day
                     but so that:

                     (a)        the initial Interest Period in respect of each
                                Term Advance shall commence on its Conversion
                                Date and shall be that stipulated in the
                                Conversion Notice by the Company and each
                                subsequent Interest Period shall commence
                                forthwith upon the expiry of the previous
                                Interest Period;

                     (b)        the final Interest Period shall end on the Term
                                Advance Maturity Date; and

                     (c)        if a Borrower fails to specify the duration of
                                an Interest Period or the Bank by 10.30 a.m. on
                                the applicable Rate Fixing Day states that it
                                does not agree to an Interest Period of other
                                than one, three or six months, that Interest
                                Period shall have a duration of three months.

           Notices pursuant to this Clause 5.7.3 may be by telephone or in
           writing, provided that if such notice is by telephone, it shall be
           confirmed in writing by close of business on the relevant Rate Fixing
           Day.

6.         CANCELLATION AND EXTENSION

           AUTOMATIC CANCELLATION OF THE COMMITMENT

6.1        The Commitment shall be automatically cancelled at close of business
           on the Availability Period End Date.

           VOLUNTARY CANCELLATION

6.2        The Company may, without penalty and by giving not less than 15 days'
           prior notice to the Bank, cancel the Commitment in whole or in part.

6.3        A notice of cancellation will be irrevocable and shall specify:

           6.3.1      the date on which the cancellation is to become effective;
                      and

           6.3.2      the amount of the Commitment to be cancelled.

6.4        Any cancellation may only take effect in respect of the unutilised
           portion of the Commitment as at the date the notice is to be
           effective.

           NO REINSTATEMENT

6.5        No amount of the Commitment cancelled under this Agreement may
           subsequently be reinstated.

           EXTENSION

6.6        Not more than 60 days but not less than 30 days prior to the
           Availability Period End Date the Company may request that the Bank
           extend the Revolving Facility for a further period of 364 days. Any
           such request shall be irrevocable and in writing. The Bank shall have
           absolute discretion as to whether to agree to such an extension, and
           the Bank shall advise the Company in writing of its decision not less
           than 20 days prior to the Availability Period End Date. If the Bank
           agrees to such extension the Revolving Facility shall be extended so
           that the Availability Period End Date becomes the day 364 days after
           the Availability Period End Date prior to such extension. The right
           to request an extension pursuant to this Clause 6.6 may be exercised
           until the Bank refuses such an extension but shall not be exercised
           after the Company has given any Conversion Notice pursuant to Clause
           5.7.

7.         INTEREST

           INTEREST RATE

7.1        The rate of interest on each Advance for its Term or, as the case may
           be, each Interest Period applicable thereto is the rate per annum
           determined by the Bank to be the aggregate of the applicable:

           7.1.1      Margin,

           7.1.2      LIBOR; and

           7.1.3      Mandatory Costs.

           DUE DATES

7.2        Except as otherwise provided in this Agreement, accrued interest on
           each Revolving Advance is payable on its Maturity Date and on each
           Term Advance is payable on the last day of each Interest Period
           applicable to it and also in the case of a Revolving Advance with a
           Term longer than six months, or in the case of a Term Advance with an
           Interest Period longer than six months, every six months after the
           commencement of its Term or Interest Period, as the case may be.

           DEFAULT INTEREST

7.3        If any Borrower fails to pay any amount payable by it under this
           Agreement, it shall, on demand by the Bank from time to time, pay
           interest on the overdue amount from the due date up to the date of
           actual payment, after as well as before judgment, at a rate (the
           "DEFAULT RATE") determined by the Bank to be one (1) per cent. per
           annum above the higher of:

           7.3.1     the rate on the overdue amount under Clause 7.1 (Interest
                     rate) immediately before the due date (but only if the
                     overdue amount is an Advance (or part thereof) and only for
                     the period up to and including the Maturity Date of that
                     Advance or, as the case may be, the last day of the current
                     Interest Period applicable to that Advance); and

           7.3.2     the rate which would have been payable if the overdue
                     amount had, during the period of non-payment, constituted
                     an Advance in the currency of the overdue amount for such
                     successive periods of such duration (not exceeding three
                     months) as the Bank may reasonably determine (each a
                     "DESIGNATED TERM").

7.4        The default rate will be determined on the first day of, or two
           Business Days before the first day of, the relevant Designated Term,
           as appropriate.

7.5        If the Bank determines that deposits in the currency of the overdue
           amount are not at the relevant time being made available by leading
           banks in the London Interbank Market, the default rate will be
           determined by reference to the cost of funds to the Bank from
           whatever sources it may reasonably select.

7.6        Default interest shall be compounded at the end of each Designated
           Term until it is paid.

           NOTIFICATION OF RATES OF INTEREST

7.7        The Bank shall promptly notify the relevant Borrower of the
           determination of any applicable rate of interest under this
           Agreement.

8.         REPAYMENT AND PREPAYMENT

           REPAYMENT OF REVOLVING ADVANCES

8.1        Each Borrower shall repay each Revolving Advance made to it in full
           on its Maturity Date to the Bank. If a Revolving Advance (the "NEW
           REVOLVING ADVANCE") is to be made to a Borrower on the day on which
           another Revolving Advance (the "MATURING REVOLVING ADVANCE") in the
           same currency is due to be repaid by such Borrower then, subject to
           the terms of this Agreement and so long as the conditions referred to
           in Clause 4.2 shall have been satisfied in relation to the New
           Revolving Advance:

           8.1.1     the Maturing Revolving Advance shall be deemed to have been
                     repaid on its Maturity Date either in whole (if the New
                     Revolving Advance is equal to or greater than the Maturing
                     Revolving Advance) or in part (if the New Advance is less
                     than the Maturing Revolving Advance); and

           8.1.2     to the extent that a Maturing Revolving Advance is so
                     deemed to have been repaid, the principal amount of the New
                     Revolving Advance to be made on such a date shall be deemed
                     to have been credited to the account of such Borrower by
                     the Bank in accordance with the terms of this Agreement
                     and, as the case may be:

                     (a)        the Bank shall only be obliged to make available
                                to such Borrower pursuant to Clause 5.6 a
                                principal amount equal to the amount (if any) by
                                which the New Revolving Advance exceeds the
                                Maturing Revolving Advance; or

                     (b)        such Borrower shall only be obliged to pay to
                                the Bank pursuant to this Clause 8.1 a principal
                                amount equal to the amount by which the Maturing
                                Revolving Advance exceeds the New Revolving
                                Advance.

8.2        On the Availability Period End Date, all outstanding Revolving
           Advances and other sums (if any) then owing under this Agreement in
           relation thereto shall in any event be repaid or paid in full.

           REPAYMENT OF TERM ADVANCES

8.3        Each Borrower shall repay each Term Advance made to it and all other
           sums (if any) then owing under this Agreement in full on the Term
           Advance Maturity Date to the Bank. No Term Advance repaid or prepaid
           may be reborrowed.

           PREPAYMENT OF ADVANCES

8.4        Any Borrower may, without penalty and on giving not less than 15
           days' prior notice to the Bank, prepay all or any part of an Advance,
           but if in part, in a minimum amount of Pound Sterling 1,000,000 and
           an integral multiple of Pound Sterling 100,000 (or the comparable
           amount in any Optional Currency).

8.5        Any notice by a Borrower of prepayment under this Agreement is
           irrevocable.

8.6        Should any person or group of persons, acting either individually or
           in concert (as defined in the City Code on Take Overs and Mergers
           effective as at the date of this Agreement) otherwise than with the
           consent of the Bank acquire control of the Company (and for the
           purpose of this Clause a single person or group of persons shall have
           acquired control if it or they own or hold more than 50% (fifty per
           cent.) of the issued share capital of the Company having the right to
           attend and vote at general meetings of the Company or more than 50%
           (fifty per cent.) of such rights), then:

           8.6.1     the Company shall immediately upon becoming aware thereof
                     notify the Bank specifying the date of such acquisition and
                     the name of such person or persons acquiring control; and

           8.6.2     thereafter no Borrower shall be permitted to give a
                     Conversion Notice or to request a Revolving Advance unless
                     the terms of the acquisition of control of the Company were
                     approved by the Board of Directors of the Company and the
                     Maturity Date for any such Revolving Advance requested
                     falls on a date not more than three months after the
                     expiration of the 30 day period referred to in Clause 8.7.

8.7        If the terms of the acquisition of control of the Company were
           approved by the Board of Directors of the Company, the Bank shall
           consult with the Company during the period of 30 days after receipt
           of the notification from the Company referred to in sub-Clause 8.6.1
           and shall be entitled to give notice of continuance of the Facility
           provided hereunder to the Company. Upon receipt of such notice of
           continuance, the right of the Borrowers to request Revolving Advances
           without the limitation referred to in sub-Clause 8.6.2 and/or to give
           a Conversion Notice shall be reinstated.

8.8        If the terms of the acquisition of control of the Company were
           approved by the Board of Directors of the Company but, at the end of
           the period of 30 days referred to in Clause 8.7 above, the Company
           has not received a notice of continuance then:

           8.8.1     the Facility shall be cancelled;

           8.8.2     any outstanding Revolving Advances with Maturity Dates
                     falling (or, in the case of any Term Advances, where the
                     Term Advance Maturity Date falls) later than three months
                     after the end of such period shall be prepaid on the date
                     falling three months after the end of such period, together
                     with accrued interest thereon up to the date of payment and
                     all other amounts payable to the Bank hereunder; and


                                      -17-

<PAGE>   18

           8.8.3     any outstanding Advances with Maturity Dates falling (or,
                     in the case of any Term Advances, where the Term Advance
                     Maturity Date falls) not later than three months after the
                     end of such period shall be repaid on their respective
                     Maturity Dates (or, as the case may be, on the Term Advance
                     Maturity Date).

8.9        If the terms of the acquisition of control of the Company were not
           approved by the Board of Directors of the Company, then unless the
           Bank shall have confirmed within 2 days of receipt of the notice
           referred to in sub-Clause 8.6.1 that the Facility shall be continued,
           the Facility shall be cancelled and any outstanding Advances shall be
           repayable on demand by the Bank together with accrued interest
           thereon up to the date of payment and all other amounts payable to
           the Bank hereunder.

8.10       Any prepayment under this Agreement shall be made together with
           accrued interest on the amount prepaid together with any amount
           payable to the Bank pursuant to Clause 22.3.

8.11       No Advance may be prepaid otherwise than in accordance with the
           express terms of this Agreement.

                     funds, or at such times or in such funds as the Bank may
                     specify to the relevant Borrower as being customary at the
                     time for the settlement of transactions in the relevant
                     currency in the place for payment.

           CURRENCY

           Subject to clauses 9.6 and 9.7:

                                      -18-

<PAGE>   19

9.4        Interest is payable in the currency in which the relevant amount in
           respect of which it is payable is denominated.

9.5        Any other amount payable under this Agreement is, except as otherwise
           provided in this Agreement, payable in Sterling.

9.6        Subject to clause 9.7, on and after the Commencement Date, any
           Advance requested to be denominated in the currency of a
           Participating Member State shall be made in the euro unit.

9.7        If and to the extent that any EMU legislation provides that an amount
           denominated either in the euro unit or in the national currency unit
           of a given Participating Member State and payable within that
           Participating Member State by crediting an account of the creditor,
           can be paid by the debtor either in the euro unit or in that national
           currency unit, a Party shall be entitled to pay that amount either in
           the euro unit or in the relevant national currency unit.

           SET-OFF AND COUNTERCLAIM

9.8        All payments made by each of the Borrowers under this Agreement shall
           be made without set-off or counterclaim.

           next Business Day.

9.10       During any extension of the due date for payment of any principal
           under this Agreement pursuant to Clause 9.9 above interest is payable
           on the principal at the rate payable on the original due date.

           PARTIAL PAYMENTS

9.11       If the Bank receives a payment insufficient to discharge all the
           amounts then due and payable by any Borrower under this Agreement,
           the Bank shall apply that payment towards the obligations of such
           Borrower under this Agreement in the following order:

           9.11.1    firstly, in or towards payment of any unpaid costs and
                     expenses of the Bank under this Agreement;

           9.11.2    secondly, in or towards payment of any accrued fees due but
                     unpaid under Clause 19.2 (Commitment Fee);

           9.11.3    thirdly, in or towards payment of any accrued interest due
                     but unpaid under this Agreement;

           9.11.4    fourthly, in or towards payment of any principal due but

<PAGE>   20

9.12       The Bank may vary the order set out in Clauses 9.11.1 to 9.11.5
           above.

9.13       Clauses 9.11 and 9.12 above shall override any appropriation made by
           any Borrower.

10.        OPTIONAL CURRENCIES

           SELECTION

10.1       No Borrower may request a Revolving Advance denominated in an
           Optional Currency unless the Bank has confirmed to such Borrower that
           the Optional Currency is readily available and freely transferable in
           the London foreign exchange market.

           CHANGE OF CURRENCY

10.2       If, on the Rate Fixing Day of a Revolving Advance to be denominated
           in an Optional Currency, the Bank determines that:

           10.2.1    it is impracticable for reasons beyond its control for the
                     Bank to fund that Advance for its Term in that Optional
                     Currency in the ordinary course of business in the London
                     Interbank Market; or

           10.2.2    the use of the proposed Optional Currency might contravene
                     any law or regulation,

           then:

           10.2.3    the Bank shall promptly and in any event before 10.30 a.m.
                     on that Rate Fixing Day notify the relevant Borrower;

           10.2.4    if the Bank receives notice from the relevant Borrower by
                     11.30 a.m. on that Rate Fixing Day to that effect, that
                     Advance will not be made; and

           10.2.5    if the Bank does not receive any notice under sub-Clause
                     10.2.4 above, that Advance will be denominated instead in
                     Sterling in an amount equal to its Original Sterling
                     Amount.

           NOTIFICATION OF RATES AND AMOUNTS

10.3       The Bank shall, on request, promptly notify the relevant Borrower of
           any applicable Bank's Spot Rate of Exchange or Original Sterling
           Amount promptly after it has been ascertained.

10.4       If a Revolving Advance which has been drawn in an Optional Currency
           is reborrowed in the same Optional Currency immediately following its
           repayment or if a Term Advance is denominated in an Optional
           Currency, then the Original Sterling Amount of such new Advance
           denominated in such Optional Currency or, as the case may be, such
           Term Advance shall be recalculated for the new Term or, as the case
           may be, each new Interest Period in accordance with the terms and
           conditions of this Agreement and if on the


                                      -20-

<PAGE>   21

           relevant Utilisation Date or, as the case may be, the first day of
           any Interest Period in respect of a Term Advance the aggregate
           Original Sterling Amount of all Advances outstanding on such date
           exceeds the Commitment, then any excess shall be repaid to the Bank
           by the relevant Borrower upon the Bank's first written demand.

11.        TAXES

           GROSS-UP

11.1       All payments by each of the Borrowers under this Agreement shall be
           made without any deductions and free and clear of and without
           deduction for or on account of any Relevant Taxes except to the
           extent that any Borrower is required by law to make payment subject
           to any such taxes. If any Relevant Tax or amounts in respect of any
           Relevant Tax must be deducted from any amounts payable or paid by any
           Borrower hereunder, such Borrower shall pay such additional amounts
           as may be necessary to ensure that the Bank receives a net amount
           equal to the full amount which it would have received had payment not
           been made subject to tax.

           "RELEVANT TAX" in relation to any payment which falls to be made
           hereunder means any present or future taxes of any nature now or
           hereafter imposed by the laws of (i) the United Kingdom, (ii) any
           other jurisdiction from which, or through which, such payment is made
           or to the taxation laws of which the relevant Borrower is at the time
           of such payment subject, (iii) any political sub-division of the
           United Kingdom or any such other jurisdiction or (iv) any federation
           or association of states of which the United Kingdom or any such
           other jurisdiction is, at the time of such payment, a member.

           TAX RECEIPTS

11.2       All Relevant Taxes required by law to be deducted or withheld by any
           Borrower from any amount paid or payable under this Agreement shall
           be paid by such Borrower when due (unless the obligation to pay is
           being disputed in good faith) and such Borrower shall, within 30 days
           of the payment being made, deliver to the Bank evidence satisfactory
           to the Bank (including all relevant tax receipts) that the payment
           has been duly remitted to the appropriate authority.

           TAX CREDITS

11.3       If any Borrower pays any additional amount (a "TAX PAYMENT") under
           Clause 11.1 and the Bank effectively obtains a refund of tax, or a
           relief or credit against tax by reason of that Tax Payment (a "TAX
           CREDIT"), and the Bank is able to identify the Tax Credit as being
           attributable to the Tax Payment, then the Bank shall reimburse to the
           relevant Borrower such amount as the Bank reasonably determines to be
           the proportion of the Tax Credit as will leave the Bank (after that
           reimbursement) in no better or worse position that it would have been
           if the Tax Payment had not been required. Nothing in this Clause
           interferes with the right of the Bank to arrange its tax affairs in
           whatever manner it thinks fit and, without prejudice to the
           foregoing, the Bank is under no obligation to


                                      -21-

<PAGE>   22

           claim a Tax Credit, or to claim a Tax Credit in priority to any other
           claim, relief, credit or deduction available to it. The Bank is not
           obliged to disclose any information regarding its tax affairs or
           computations to any Borrower.

           QUALIFYING BANK

11.4       If, otherwise than as a result of the introduction of, change in, or
           change in the interpretation, administration or application of, any
           law or regulation or any practice or concession of the Inland Revenue
           after the Signing Date, the Bank ceases to be a Qualifying Bank no
           Borrower which is tax resident in the United Kingdom shall be liable
           to pay to the Bank under Clause 11.1 (Gross-up) any amount in respect
           of taxes levied or imposed by the UK or any taxing authority thereof
           or therein in excess of the amount it would have been obliged to pay
           if the Bank had been or had not ceased to be a Qualifying Bank.

12.        MARKET DISRUPTION

           MARKET DISRUPTION

12.1       If, in relation to any proposed Advance:

           12.1.1    the Bank is unable to obtain from leading banks a rate for
                     the purposes of determining the applicable LIBOR or the
                     Bank otherwise determines that adequate and fair means do
                     not exist for ascertaining the applicable LIBOR; or

           12.1.2    in the opinion of the Bank:

                     (a)        matching deposits may not be available to it in
                                the London Interbank Market in the ordinary
                                course of business to fund an Advance; or

                     (b)        the cost to it of matching deposits in the
                                London Interbank Market would be in excess of
                                the relevant LIBOR,

                     the Bank shall notify the Company by 10.30 a.m. or as soon
                     as is practicable thereafter on the Rate Fixing Day of the
                     fact and that this Clause is in operation.

12.2       After any notification under Clause 12.1 above:

           12.2.1    subject to sub-Clause 12.2.3 below if the affected Advance
                     was a Revolving Advance it shall be made in Sterling in an
                     amount equal to its Original Sterling Amount (unless
                     Sterling was the original currency of the relevant
                     Advance);

           12.2.2    subject to sub-Clause 12.2.3 below, no further notices of
                     Utilisation by telephone or Requests for Advances or
                     Conversion Notices in respect of Term Advances to be
                     denominated in the original currency of the affected
                     Advance may be delivered until the Bank notifies the
                     Company that the event specified in the notification no
                     longer prevails;




                                      -22-

<PAGE>   23

12.2.3     the relevant Borrower may, by notice to the Bank by 11.00 a.m. (or,
           if later, within 30 minutes of receipt by the Company of a
           notification under sub-Clause 12.1.2) on the Rate Fixing Day, as the
           case may be: (i) elect for the notice of Utilisation by telephone or
           the Request to be cancelled without penalty; (ii) if the affected
           Advance was a Revolving Advance to be made in an Optional Currency or
           is a Term Advance outstanding in an Optional Currency, elect for the
           Advance to be made in or converted into an Optional Currency other
           than a currency affected by the event specified in the notification
           or (iii) elect for the Advance to be made in accordance with the
           Request or, if the affected Advance is a Term Advance, elect for the
           Advance to be maintained in such currency notwithstanding the event
           specified in the notification. If any Borrower requires an affected
           Advance to be made in the original currency selected for such Advance
           or maintained in such currency notwithstanding the event specified in
           the notification then within five Business Days of receipt of the
           notification, the Company and the Bank shall enter into negotiations
           for a period of not more than 25 days with a view to agreeing a
           substitute basis for determining the rate of interest and/or funding
           applicable to the affected Advance and any future Advances in the
           currency of the affected Advance provided that if no substitute basis
           is agreed within that period:

           (a)       the Bank shall certify to the Company (such certificate to
                     be conclusive) the alternative interest rate calculated in
                     accordance with sub-Clause 12.2.4 below;

           (b)       the certificate may make provision for different funding

           (c)       the certificate shall be binding on each relevant Borrower

                     certificate is not acceptable and that each relevant
                     Borrower shall prepay in full the relevant Advances on a

12.3       During the period when any substitute basis is in force in relation
           to a particular currency, the Bank shall periodically determine
           whether the circumstances referred to in Clause 12.1 above still
           apply and, if they do not, shall forthwith give notice in writing to
           the Company of the date on which the substitute basis will cease to

13.        INCREASED COSTS

           INCREASED COSTS - SERVICE OF DEMAND

13.1       If the result of any introduction of or change in any law or
           regulation after the Signing Date, or of any change in the
           application or interpretation of any such changed law or regulation
           or compliance by the Bank with any such changed law or regulation
           after the Signing Date (including, without limitation, any law or
           regulation relating to taxation, any reserve, special deposit, cash
           ratio, liquidity or capital adequacy requirement or any form of
           banking or monetary control but excluding (i) changes arising from
           the implementation by any authority having jurisdiction over the Bank
           or its holding company of the matters set out in the statement
           prepared by the Basle Committee on Banking Regulations and
           Supervisory Practices dated July 1988 and entitled "International
           Convergence of Capital Measurement and Capital Standards" (as amended
           in November 1991) and (ii) changes arising from the implementation in
           whole or in part by any authority having jurisdiction over the Bank
           or its holding company of the proposals contained in the matters set
           out in the EC Directive 93/6/EEC of 15 March 1993 on the capital
           adequacy of investment firms and credit institutions) is that the
           Bank incurs an increased cost, then the Bank will promptly notify the
           Company of the relevant event and the Company shall on demand pay to
           the Bank such amount as the Bank certifies in the demand will
           compensate it for the applicable increased cost.

13.2       In this Clause 13 "INCREASED COST" means:

           13.2.1    an additional cost incurred by the Bank as a result of it
                     having entered into, or performing, maintaining or funding
                     its obligations under, this Agreement; or

           13.2.2    that portion of an additional cost incurred by the Bank in
                     making, funding or maintaining all or any advances
                     comprised in a class of advances formed by or including the
                     Advances made or to be made by it under this Agreement as
                     is attributable to it making, funding, or maintaining such
                     advances; or

           13.2.3    a reduction in any amount payable to the Bank or the
                     effective return to the Bank under this Agreement or on its
                     capital; or

           13.2.4    any payment made or interest or other return on or
                     calculated by reference to any amount received or
                     receivable by the Bank under this Agreement which is
                     forgone.

13.3       When calculating an increased cost, the Bank may allocate or spread
           costs, liabilities and losses to or across its liabilities or assets,
           or any class of liabilities or assets, and on such basis, as it
           reasonably considers appropriate.

           INCREASED COSTS - EXCEPTIONS

13.4       An increased cost does not include any increased cost:

           13.4.1    compensated for by the payment of the Mandatory Cost;

           13.4.2    compensated for by the operation of Clause 11 (Taxes);

           13.4.3    attributable to any change in the rate of tax on the
                     overall net income of the Bank (or the overall net income
                     of a division or branch of the Bank) imposed in the
                     jurisdiction in which its principal office or the relevant
                     lending office for the time being is situate;

           13.4.4    payable to an assignee or transferee of the Bank at the
                     time of an assignment, transfer or novation under Clause 25
                     (Changes to the Parties), but only to the extent that the
                     increased cost would not have been payable to the
                     assigning, transferring or novating Bank; or

           13.4.5    which is attributable to the introduction of the euro other
                     than an increased cost which is being incurred generally by
                     banks transacting euro business in the London interbank
                     market.

14.        ILLEGALITY

14.1       If it is or becomes unlawful for the Bank to give effect to any of
           its obligations as contemplated by this Agreement or to fund or
           maintain any Advance, then the Bank shall notify the Company
           accordingly and on the Maturity Date or, as the case may be, the last
           day of an Interest Period of each relevant Advance (or such earlier
           date as the relevant law or directive may require) the relevant
           Borrower shall repay or prepay, as the case may be, any Advances made
           to it by the Bank together with all other amounts payable by it to
           the Bank under this Agreement.

14.2       The Bank's Commitment shall be cancelled on the date of a
           notification under Clause 14.1 above.

15.        TAXES AND INCREASED COSTS - ADDITIONAL RIGHTS

           PREPAYMENT AND CANCELLATIONS

15.1       If any Borrower is required to pay any additional amounts to the Bank
           under Clause 11 (Taxes) or compensation under Clause 13 (Increased
           Costs), the Company may, whilst the circumstances giving rise to the
           requirement continue, serve a notice of prepayment and cancellation
           in relation to all or all affected Advances on the Bank.


                                      -25-

<PAGE>   26

15.2       On the tenth Business Day after the date of service of the notice the
           relevant Borrower shall prepay the relevant Advance or Advances made
           to it by the Bank together with all other amounts in relation to such
           Advance(s) payable by it to the Bank under this Agreement.

15.3       To the extent of the Advances referred to in the notice of prepayment
           and cancellation, but not further or otherwise, the Bank's Commitment
           shall be cancelled on the date of service of the notice.

           MITIGATION

15.4       If, in respect of the Bank, circumstances arise which would or would,
           with the giving of notice, result in:

           15.4.1    any additional amounts becoming payable under Clause 11
                     (Taxes); or

           15.4.2    any increased cost becoming payable under Clause 13
                     (Increased Costs); or

           15.4.3    any prepayment, payment or cancellation under Clause 14
                     (Illegality),

           then the Bank shall endeavour to take such steps as are reasonably
           open to it to mitigate or remove those circumstances (including
           seeking recovery for the account of the relevant Borrower where
           reasonably practicable and/or transferring its rights and obligations
           under this Agreement to another bank or financial institution
           acceptable to the Company).

15.5       Clause 15.4 above does not:

           15.5.1    prejudice the obligations of any Borrower under this
                     Agreement (including, without limitation, under the Clauses
                     referred to in Clause 15.4 above); or

           15.5.2    require the Bank to take any action which, in its opinion,
                     might be in any way prejudicial to it or conflict with its
                     banking policies.

           a Borrower it will only be an Event of Default if the event is, in
           the reasonable opinion of the Bank, reasonably likely to affect
           materially and adversely the Company's ability to perform its
           obligations under this Agreement.

18.2       Any Borrower defaults in payment on the due date of any amount

           not remedied within seven Business Days after the Bank gives notice
           to the Company and the relevant Borrower of the default.

           BREACH OF OTHER OBLIGATIONS

18.3       Any Borrower fails to observe or perform any other obligation on its
           part contained in this Agreement (other than those which, in the
           reasonable opinion of the Bank, are not material), and (in the case
           of a breach capable of being remedied) fails to remedy the breach
           within fourteen Business Days after the date on which the Company and
           the relevant Borrower receive notice of the breach from the Bank.

           MISREPRESENTATION

18.4       A representation, warranty or statement made or repeated in, this
           Agreement by any Borrower proves to have been untrue in any material
           particular when made or deemed to be repeated.

           reduced, the Bank shall be entitled to recover the value or amount of
           such security or payment from the Company subsequently as if such
           settlement or discharge had not occurred.

22.9       The Bank shall not be obliged before exercising any of the rights,

           22.9.1    to make any demand of any other Borrower;

                     respect of any of the obligations of any other Borrower
                     hereunder.

22.10      The Company agrees that, so long as any amounts are or may be owed by
           any Borrower hereunder or any Borrower is under any actual or
           contingent obligations hereunder, it shall not exercise any rights

31.        DESIGNATION OF ACCEDING AND SECEDING BORROWERS

31.1       The Company may request that any of its Subsidiaries incorporated in
           England and Wales and, with the prior written consent of the Bank
           (such consent not to be unreasonably withheld or delayed) any other
           Subsidiary of the Company becomes an Acceding Borrower by delivering
           or procuring the delivery to the Bank a Borrower's Accession Notice
           duly executed by the Company and the relevant Subsidiary provided
           that if such Subsidiary is not resident in the United Kingdom for tax
           purposes the Company and the Bank agree to make such amendments to
           this Agreement as may be reasonably required at the time in order to
           allow such Subsidiary to pay interest to the Bank without deduction
           or withholding of any Relevant Tax and to provide such Subsidiary
           with equivalent rights, mutatis mutandis, to those contained in
           Clause 11.4 (Qualifying Bank).

31.2       Upon delivery of a Borrower's Accession Notice, the relevant
           Subsidiary shall become an Acceding Borrower and shall, subject to
           the terms and conditions of this Agreement acquire all the rights and
           assume all the obligations of a Borrower hereunder provided that the
           Bank has confirmed to the Company that it has received, in form and
           substance satisfactory to it, all the documents set out in Part II of
           Schedule 1.

31.3       The Company undertakes that it shall procure that each Acceding
           Borrower shall provide the Bank with each of the documents listed in
           Part II of Schedule 1.

31.4       If at any time any Borrower (other than the Company) has no actual or
           contingent obligation under this Agreement, the Company may deliver a
           Borrower's Cessation Notice to the Bank in which event such Borrower
           shall forthwith cease to be a Borrower upon receipt by the Bank of
           such notice.

32.        CHANGE OF CURRENCY

32.1       If more than one currency or currency unit are at the same time
           recognised by the central bank of any country as the lawful currency
           of that country, then:

           32.1.1    any reference in this Agreement to, and any obligations
                     arising under this Agreement in, the currency of that
                     country shall be translated into, or paid in, the currency
                     unit of that country designated by the Bank acting
                     reasonably and in consultation with the Company; and

           32.1.2    any translation from one currency unit to another shall be
                     at the official rate of exchange recognised by the relevant
                     central bank for the conversion of that currency or
                     currency unit into the other, rounded up or down by the
                     Bank acting reasonably.

32.2       If a change in any currency of a country occurs, the Bank and the
           Company will negotiate in good faith in order to agree any amendments
           to this Agreement to reflect market practice at that time with regard
           to the occurrence of EMU within the European Union or any part(s) of
           it and the new currency and to put the Bank and the Borrowers in the
           same position, so far as is possible, that they would have been in if
           no change in currency had occurred.


                                      -41-

<PAGE>   42

32.3       The Bank and the Company agree that the occurrence or non-occurrence
           of EMU within the European Union or part(s) of it and/or any event or
           events associated with EMU and/or the introduction of any new
           currency in all or any part of the European Union will not result in
           the discharge cancellation, rescission or termination in whole or in
           pat of this Agreement or give any party hereto the right to cancel,
           rescind, terminate or vary (other than as aforesaid) this Agreement
           in whole or in part or give rise to an Event of Default.

33.        COUNTERPARTS

           This Agreement may be executed in any number of counterparts each of
           which shall be an original and all of such counterparts taken
           together shall be delivered to constitute one and the same
           instrument.

34.        APPLICABLE LAW AND JURISDICTION

34.1       The law of England and Wales is the law applicable to this Agreement.

34.2       Each of the Borrowers irrevocably agrees for the benefit of the Bank
           that the courts of England shall have jurisdiction to hear and
           determine any suit, action or proceeding, and to settle any disputes,
           which may arise out of or in connection with this Agreement and, for
           such purposes, irrevocably submits to the jurisdiction of such
           courts.

34.3       Each of the Borrowers which is not incorporated in England and Wales
           agrees that the process by which any suit, action or proceeding is
           begun in England and Wales may be served on it by being delivered to
           the Company at its registered office for the time being and hereby
           appoints the Company (and the Company accepts such appointment) for
           such purposes. If the appointment of the person mentioned in this
           Clause 34.3 ceases to be effective in respect of any or all of the
           Borrowers such Borrower or Borrowers shall immediately appoint a
           further person in England and Wales to accept service of process on
           its behalf in England and Wales and, failing such appointment within
           fifteen days, the Bank acting reasonably shall be entitled to appoint
           such a person by notice to such Borrower or Borrowers. Nothing
           contained herein shall affect the right to serve process in any other
           manner permitted by law.

34.4       Each of the Borrowers irrevocably waives any objection which it might
           now or hereafter have to the courts referred to in Clause 34.2 being
           nominated as the forum to hear and determine any suit, action or
           proceeding, and to settle any disputes, which may arise out of or in
           connection with this Agreement and agrees not to claim that any such
           court is not a convenient or appropriate forum.

34.5       The submission to the jurisdiction of the courts referred to in
           Clause 34.2 shall not (and shall not be construed so as to) limit the
           right of the Bank to take proceedings against any of the Borrowers in
           any other court of competent jurisdiction nor shall the taking of
           proceedings in any one or more jurisdictions preclude the taking of
           proceedings in any other jurisdiction (whether concurrently or not)
           if and to the extent permitted by applicable law.

         NUMBER OF REQUESTS AND UTILISATIONS

2.3      Any number of Requests may be delivered on the same day and/or
         specifying the same Utilisation Date, whether or not the currencies and

         FURTHER CONDITIONS PRECEDENT

4.2      The obligation of the Bank to make each Utilisation is subject to the
         further conditions precedent that:

         4.2.1    on both the date of the Request and the Utilisation Date for
                  that Utilisation:

                  (a)  the representations and warranties in Clause 16
                       (Representations and Warranties) to be repeated on those

                       the Utilisation; and

                  (b)  no Default is outstanding or might result from the
                       Utilisation; and

         4.2.2    the Utilisation would not cause Clause 2.2 (Overall facility

         business in London on the day on which such telephone notice is, or is
         deemed to have been, given.

         COMPLETION OF REQUESTS

5.3      When giving a notice of Utilisation by telephone and when completing
         the Request, the relevant Borrower must ensure that:

         5.3.1    the Utilisation Date is a Business Day;

         5.3.2    only one currency is specified and that the Requested Amount
                  is:

                  (c)  if the currency is an Optional Currency other than
                       Dollars, a minimum and integral multiple of the amounts
                       agreed between the relevant Borrower and the Bank before
                       the telephone notice of Utilisation or delivery of that
                       Request; or

                  (d)  such other amounts as the Bank and the relevant Borrower
                       may agree;

         5.3.3    only one Term is specified which:

                  (a)  does not overrun the Final Maturity Date; and

                  (b)  is a period of an approved duration or of an optional
                       duration; and

         5.3.4    the payment instructions comply with Clause 9 (Payments).

         In this Clause:

         "APPROVED DURATION" means a period of 1, 2, 3 or 6 months; and

         "OPTIONAL DURATION" means any other period not exceeding 6 months.

         SELECTION OF TERM OF OPTIONAL DURATION

5.4      If the relevant Borrower selects a Term of an optional duration, it may
         also select at the time of the telephone notice of Utilisation and in
         the relevant Request a Term of any approved duration to apply if the
         selection of a Term of an optional duration becomes ineffective in
         accordance with Clause 5.5.2.

5.5      If:

         5.5.1    the relevant Borrower requests a Term of an optional duration;
                  and

         5.5.2    the Bank notifies such Borrower not later than 11.30 a.m. on
                  the date of receipt by it of the relevant Request or telephone
                  notice of Utilisation pursuant to Clause 5.1 or Clause 5.2
                  respectively that it does not agree to that request,

         the Term for the proposed Utilisation shall be the alternative period

         AUTOMATIC CANCELLATION OF THE COMMITMENT

         the Final Maturity Date.

         VOLUNTARY CANCELLATION

6.2      The Company may, without penalty and by giving not less than 15 days'
         prior notice to the Bank, cancel the Commitment in whole or in part.

6.3      A notice of cancellation will be irrevocable and shall specify:

         6.3.1    the date on which the cancellation is to become effective; and

         6.3.2    the amount of the Commitment to be cancelled.

6.4      Any cancellation may only take effect in respect of the unutilised
         portion of the Commitment as at the date the notice is to be effective.

         NO REINSTATEMENT

6.5      No amount of the Commitment cancelled under this Agreement may
         subsequently be reinstated.

7.       INTEREST

         INTEREST RATE

7.1      The rate of interest on each Advance for its Term is the rate per annum
         determined by the Bank to be the aggregate of the applicable:

         7.1.1    Margin,

         7.1.2    LIBOR; and

         7.1.3    Mandatory Costs.

         DUE DATES

7.2      Except as otherwise provided in this Agreement, accrued interest on
         each Advance is payable on its Maturity Date and also, in the case of
         an Advance with a term longer than six months, on the date falling six
         months after its Utilisation Date.


                                      -12-
<PAGE>   13

         DEFAULT INTEREST

7.3      If any Borrower fails to pay any amount payable by it under this
         Agreement, it shall, on demand by the Bank from time to time, pay
         interest on the overdue amount from the due date up to the date of
         actual payment, after as well as before judgment, at a rate (the
         "DEFAULT RATE") determined by the Bank to be one (1) per cent. per
         annum above the higher of:

         7.3.1    the rate on the overdue amount under Clause 7.1 (Interest
                  rate) immediately before the due date (but only if the overdue
                  amount is an Advance (or part thereof) and only for the period
                  up to and including the Maturity Date of that Advance); and

         7.3.2    the rate which would have been payable if the overdue amount
                  had, during the period of non-payment, constituted an Advance
                  in the currency of the overdue amount for such successive
                  Terms of such duration (not exceeding three months) as the
                  Bank may reasonably determine (each a "DESIGNATED TERM").

7.4      The default rate will be determined on the first day of, or two
         Business Days before the first day of, the relevant Designated Term, as
         appropriate.

7.5      If the Bank determines that deposits in the currency of the overdue
         amount are not at the relevant time being made available by leading
         banks in the London Interbank Market, the default rate will be
         determined by reference to the cost of funds to the Bank from whatever
         sources it may reasonably select.

7.6      Default interest shall be compounded at the end of each Designated Term
         until it is paid.

         NOTIFICATION OF RATES OF INTEREST

7.7      The Bank shall promptly notify the relevant Borrower of the
         determination of any applicable rate of interest under this Agreement.

8.       REPAYMENT AND PREPAYMENT

         REPAYMENT OF ADVANCES

8.1      Each Borrower shall repay each Advance made to it in full on its
         Maturity Date to the Bank. If an Advance (the "NEW ADVANCE") is to be
         made to a Borrower on the day on which another Advance (the "MATURING
         ADVANCE") in the same currency is due to be repaid by such Borrower
         then, subject to the terms of this Agreement and so long as the
         conditions referred to in Clause 4.2 shall have been satisfied in
         relation to the New Advance:

         8.1.1    the Maturing Advance shall be deemed to have been repaid on
                  its Maturity Date either in whole (if the New Advance is equal
                  to or greater than the Maturing Advance) or in part (if the
                  New Advance is less than the Maturing Advance); and


                                      -13-
<PAGE>   14

         8.1.2    to the extent that a Maturing Advance is so deemed to have
                  been repaid, the principal amount of the New Advance to be
                  made on such a date shall be deemed to have been credited to
                  the account of such Borrower by the Bank in accordance with
                  the terms of this Agreement and, as the case may be:

                  (a)  the Bank shall only be obliged to make available to such
                       Borrower pursuant to Clause 5.6 a principal amount equal
                       to the amount (if any) by which the New Advance exceeds
                       the Maturing Advance; or

                  (b)  such Borrower shall only be obliged to pay to the Bank
                       pursuant to this Clause 8.1 a principal amount equal to
                       the amount by which the Maturing Advance exceeds the New
                       Advance.

8.2      On the Final Maturity Date, all outstanding Advances and other sums (if
         any) then owing under this Agreement shall in any event be repaid or
         paid in full.

         PREPAYMENT OF ADVANCES

8.3      Any Borrower may, without penalty and on giving not less than 15 days'
         prior notice to the Bank, prepay all or any part of an Advance, but if
         in part, in a minimum amount of Pound Sterling 1,000,000 and an
         integral multiple of Pound Sterling 100,000 (or the comparable amount
         in any Optional Currency).

8.4      Any notice by a Borrower of prepayment under this Agreement is
         irrevocable.

8.5      Should any person or group of persons, acting either individually or in
         concert (as defined in the City Code on Take Overs and Mergers
         effective as at the date of this Agreement) otherwise than with the
         consent of the Bank acquire control of the Company (and for the purpose
         of this Clause a single person or group of persons shall have acquired
         control if it or they own or hold more than 50% (fifty per cent.) of
         the issued share capital of the Company having the right to attend and
         vote at general meetings of the Company or more than 50% (fifty per
         cent.) of such rights), then:

         8.5.1    the Company shall immediately upon becoming aware thereof
                  notify the Bank specifying the date of such acquisition and
                  the name of such person or persons acquiring control; and

         8.5.2    thereafter no Borrower shall be permitted to request an
                  Advance unless the terms of the acquisition of control of the
                  Company were approved by the Board of Directors of the Company
                  and the Maturity Date for any Advance requested falls on a
                  date not more than three months after the expiration of the 30
                  day period referred to in Clause 8.6.

8.6      If the terms of the acquisition of control of the Company were approved
         by the Board of Directors of the Company, the Bank shall consult with
         the Company during the period of 30 days after receipt of the
         notification from the Company referred to in sub-Clause 8.5.1 and shall
         be entitled to give notice of




                                      -14-
<PAGE>   15

         continuance of the Facility provided hereunder to the Company. Upon
         receipt of such notice of continuance, the right of the Borrowers to
         request an Advance without the limitation referred to in sub-Clause
         8.5.2 shall be reinstated.

8.7      If the terms of the acquisition of control of the Company were approved
         by the Board of Directors of the Company but, at the end of the period
         of 30 days referred to in Clause 8.6 above, the Company has not
         received a notice of continuance then:

         8.7.1    the Facility shall be cancelled;

         8.7.2    any outstanding Advances with Maturity Dates falling later
                  than three months after the end of such period shall be
                  prepaid on the date falling three months after the end of such
                  period, together with accrued interest thereon up to the date
                  of payment and all other amounts payable to the Bank
                  hereunder; and

         8.7.3    any outstanding Advances with Maturity Dates falling not later
                  than three months after the end of such period shall be repaid
                  on their respective Maturity Dates.

8.8      If the terms of the acquisition of control of the Company were not
         approved by the Board of Directors of the Company, then unless the Bank
         shall have confirmed within 2 days of receipt of the notice referred to
         in sub-Clause 8.5.1 that the Facility shall be continued, the Facility
         shall be cancelled and any outstanding Advances shall be repayable on
         demand by the Bank together with accrued interest thereon up to the
         date of payment and all other amounts payable to the Bank hereunder.

8.9      Any prepayment under this Agreement shall be made together with accrued
         interest on the amount prepaid together with any amount payable to the
         Bank pursuant to Clause 22.3.

8.10     No Advance may be prepaid otherwise than in accordance with the express
         terms of this Agreement.

9.       PAYMENTS

9.1      All payments by each of the Borrowers or the Bank under this Agreement

<PAGE>   16

         9.2.2    if in Dollars on the due date in Dollars and in same day

                  for payment on the due date in lawful money of the country of
                  that Optional Currency, in immediately available funds, or at
                  such times or in such funds as the Bank may specify to the
                  relevant Borrower as being customary at the time for the
                  settlement of transactions in the relevant currency in the
                  place for payment.

         CURRENCY

         Subject to clauses 9.6 and 9.7:

9.3      A repayment or prepayment of an Advance is payable in the currency in
         which the Advance is denominated.

9.4      Interest is payable in the currency in which the relevant amount in
         respect of which it is payable is denominated.

9.5      Any other amount payable under this Agreement is, except as otherwise
         provided in this Agreement, payable in Sterling.

9.6      Subject to clause 9.7, on and after the Commencement Date, any Advance
         requested to be denominated in the currency of a Participating Member
         State shall be made in the euro unit.

9.7      If and to the extent that any EMU legislation provides that an amount
         denominated either in the euro unit or in the national currency unit of
         a given Participating Member State and payable within that
         Participating Member State by crediting an account of the creditor, can
         be paid by the debtor either in the euro unit or in that national
         currency unit, a Party shall be entitled to pay that amount either in
         the euro unit or in the relevant national currency unit.

         SET-OFF AND COUNTERCLAIM

9.8      All payments made by each of the Borrowers under this Agreement shall
         be made without set-off or counterclaim.

         NON-BUSINESS DAYS

9.9      If a payment under this Agreement is due on a day which is not a
         Business Day, then the due date for the payment shall instead be the
         next Business Day.

9.10     During any extension of the due date for payment of any principal under
         this Agreement pursuant to Clause 9.9 above interest is payable on the

         PARTIAL PAYMENTS

9.11     If the Bank receives a payment insufficient to discharge all the
         amounts then due and payable by any Borrower under this Agreement, the
         Bank shall apply that payment towards the obligations of such Borrower
         under this Agreement in the following order:


                                      -16-
<PAGE>   17

         9.11.1   firstly, in or towards payment of any unpaid costs and
                  expenses of the Bank under this Agreement;

         9.11.2   secondly, in or towards payment of any accrued fees due but
                  unpaid under Clause 19.2 (Commitment Fee);

         9.11.3   thirdly, in or towards payment of any accrued interest due but
                  unpaid under this Agreement;

         9.11.4   fourthly, in or towards payment of any principal due but
                  unpaid under this Agreement, and

                  under this Agreement.

9.12     The Bank may vary the order set out in Clauses 9.11.1 to 9.11.5 above.

9.13     Clauses 9.11 and 9.12 above shall override any appropriation made by
         any Borrower.

10.      OPTIONAL CURRENCIES

         SELECTION

10.1     No Borrower may request an Advance denominated in an Optional Currency
         unless the Bank has confirmed to such Borrower that the Optional
         Currency is readily available and freely transferable in the London
         foreign exchange market.

         CHANGE OF CURRENCY

10.2     If, on the Rate Fixing Day of an Advance to be denominated in an
         Optional Currency, the Bank determines that:

         10.2.1   it is impracticable for reasons beyond its control for the
                  Bank to fund the Advance for its Term in that Optional
                  Currency in the ordinary course of business in the London
                  Interbank Market; or

         10.2.2   the use of the proposed Optional Currency might contravene any
                  law or regulation,

         then:

         10.2.3   the Bank shall promptly and in any event before 10.30 a.m. on
                  that Rate Fixing Day notify the relevant Borrower;

         10.2.4   if the Bank receives notice from the relevant Borrower by
                  11.30 a.m. on that Rate Fixing Day to that effect, the Advance
                  will not be made; and

         10.2.5   if the Bank does not receive any notice under sub-Clause
                  10.2.4 above, the Advance will be denominated instead in
                  Sterling in an amount equal to its Original Sterling Amount.

         NOTIFICATION OF RATES AND AMOUNTS

10.3     The Bank shall, on request, promptly notify the relevant Borrower of
         any applicable Bank's Spot Rate of Exchange or Original Sterling Amount
         promptly after it has been ascertained.

10.4     If an Advance which has been drawn in an Optional Currency is
         reborrowed in the same Optional Currency immediately following its
         repayment, then the Original Sterling Amount of such new Advance
         denominated in such Optional Currency shall be recalculated for the new
         Term in accordance with the terms and conditions of this Agreement and
         if on the relevant Utilisation Date the aggregate Original Sterling
         Amount of all Advances outstanding on such date exceeds the Commitment,
         then any excess shall be repaid to the Bank by the relevant Borrower
         upon the Bank's first written demand.

11.      TAXES

         GROSS-UP

11.1     All payments by each of the Borrowers under this Agreement shall be
         made without any deductions and free and clear of and without deduction
         for or on account of any Relevant Taxes except to the extent that any
         Borrower is required by law to make payment subject to any such taxes.
         If any Relevant Tax or amounts in respect of any Relevant Tax must be
         deducted from any amounts payable or paid by any Borrower hereunder,
         such Borrower shall pay such additional amounts as may be necessary to
         ensure that the Bank receives a net amount equal to the full amount
         which it would have received had payment not been made subject to tax.

         "RELEVANT TAX" in relation to any payment which falls to be made
         hereunder means any present or future taxes of any nature now or
         hereafter imposed by the laws of (i) the United Kingdom, (ii) any other
         jurisdiction from which, or through which, such payment is made or to
         the taxation laws of which the relevant Borrower is at the time of such
         payment subject, (iii) any political sub-division of the United Kingdom
         or any such other jurisdiction or (iv) any federation or association of
         states of which the United Kingdom or any such other jurisdiction is,
         at the time of such payment, a member.

         TAX RECEIPTS

11.2     All Relevant Taxes required by law to be deducted or withheld by any
         Borrower from any amount paid or payable under this Agreement shall be
         paid by such Borrower when due (unless the obligation to pay is being
         disputed in good faith) and such Borrower shall, within 30 days of the
         payment being made, deliver to the Bank evidence satisfactory to the
         Bank (including all relevant tax receipts) that the payment has been
         duly remitted to the appropriate authority.

         TAX CREDITS

11.3     If any Borrower pays any additional amount (a "TAX PAYMENT") under
         Clause 11.1 and the Bank effectively obtains a refund of tax, or a
         relief or credit against



                                      -18-
<PAGE>   19


         tax by reason of that Tax Payment (a "TAX CREDIT"), and the Bank is
         able to identify the Tax Credit as being attributable to the Tax
         Payment, then the Bank shall reimburse to the relevant Borrower such
         amount as the Bank reasonably determines to be the proportion of the
         Tax Credit as will leave the Bank (after that reimbursement) in no
         better or worse position that it would have been if the Tax Payment had
         not been required. Nothing in this Clause interferes with the right of
         the Bank to arrange its tax affairs in whatever manner it thinks fit
         and, without prejudice to the foregoing, the Bank is under no
         obligation to claim a Tax Credit, or to claim a Tax Credit in priority
         to any other claim, relief, credit or deduction available to it. The
         Bank is not obliged to disclose any information regarding its tax
         affairs or computations to any Borrower.

         QUALIFYING BANK

11.4     If, otherwise than as a result of the introduction of, change in, or
         change in the interpretation, administration or application of, any law
         or regulation or any practice or concession of the Inland Revenue after
         the Signing Date, the Bank ceases to be a Qualifying Bank no Borrower
         shall be liable to pay to the Bank under Clause 11.1 (Gross-up) any
         amount in respect of taxes levied or imposed by the UK or any taxing
         authority thereof or therein in excess of the amount it would have been
         obliged to pay if the Bank had been or had not ceased to be a
         Qualifying Bank.

12.      MARKET DISRUPTION

         MARKET DISRUPTION

12.1     If, in relation to any proposed Utilisation:

         12.1.1   the Bank is unable to obtain from leading banks a rate for the
                  purposes of determining the applicable LIBOR or the Bank
                  otherwise determines that adequate and fair means do not exist
                  for ascertaining the applicable LIBOR; or

         12.1.2   in the opinion of the Bank:

                  (a)  matching deposits may not be available to it in the
                       London Interbank Market in the ordinary course of
                       business to fund an Advance; or

                  (b)  the cost to it of matching deposits in the London
                       Interbank Market would be in excess of the relevant
                       LIBOR,

                  the Bank shall notify the Company by 10.30 a.m. or as soon as
                  is practicable thereafter on the Rate Fixing Day of the fact
                  and that this Clause is in operation.

12.2     After any notification under Clause 12.1 above:

         12.2.1   subject to sub-Clause 12.2.3 below the relevant Advance shall
                  be made in Sterling in an amount equal to its Original
                  Sterling Amount (unless Sterling was the original currency of
                  the relevant Advance);



                                      -19-
<PAGE>   20

         12.2.2   subject to sub-Clause 12.2.3 below, no further notices of
                  Utilisation by telephone or Requests for Advances to be
                  denominated in the original currency of the affected Advance
                  may be delivered until the Bank notifies the Company that the
                  event specified in the notification no longer prevails;

         12.2.3   the relevant Borrower may, by notice to the Bank by 11.00 a.m.
                  (or, if later, within 30 minutes of receipt by the Company of
                  a notification under sub-Clause 12.1.2) on the Rate Fixing
                  Day: (i) elect for the notice of Utilisation by telephone or
                  the Request to be cancelled without penalty; (ii) if the
                  Advance was to be made in an Optional Currency, elect for the
                  Advance to be made in an Optional Currency other than a
                  currency affected by the event specified in the notification
                  or (iii) elect for the Advance to be made in accordance with
                  the Request notwithstanding the event specified in the
                  notification. If any Borrower requires an affected Advance to
                  be made in the original currency selected for such Advance
                  notwithstanding the event specified in the notification then
                  within five Business Days of receipt of the notification, the
                  Company and the Bank shall enter into negotiations for a
                  period of not more than 25 days with a view to agreeing a
                  substitute basis for determining the rate of interest and/or
                  funding applicable to the affected Advance and any future
                  Advances in the currency of the affected Advance provided that
                  if no substitute basis is agreed within that period:

                  (a)  the Bank shall certify to the Company (such certificate
                       to be conclusive) the alternative interest rate
                       calculated in accordance with sub-Clause 12.2.4 below;

                  (b)  the certificate may make provision for different funding
                       periods and shall be retroactive to the beginning of the
                       then current Term; and

                  (c)  the certificate shall be binding on each relevant
                       Borrower unless the Company gives notice to the Bank
                       within five Business Days of the receipt of the
                       certificate that the certificate is not acceptable and
                       that each relevant Borrower shall prepay in full the
                       relevant Advances on a Business Day specified in the
                       notice, which shall be not less than five nor more than
                       thirty days after the date of the Bank's certificate to
                       the Company; and

         12.2.4   for the purposes of sub-Clause 12.2.3(a) above the rate of
                  interest on each Advance shall be the rate certified by the
                  Bank as the rate per annum determined by the Bank to be the
                  aggregate of:

                  (a)  the Margin;

                  (b)  the rate notified by the Bank, on or before the last day
                       of its Term, as being the cost to the Bank of funding the
                       Advance from such other sources as it may reasonably
                       select; and



                                      -20-
<PAGE>   21


                  (c)  the applicable Mandatory Cost if any.

12.3     During the period when any substitute basis is in force in relation to
         a particular currency, the Bank shall periodically determine whether
         the circumstances referred to in Clause 12.1 above still apply and, if
         they do not, shall forthwith give notice in writing to the Company of
         the date on which the substitute basis will cease to apply.

13.      INCREASED COSTS

         INCREASED COSTS - SERVICE OF DEMAND

13.1     If the result of any introduction of or change in any law or regulation
         after the Signing Date, or of any change in the application or
         interpretation of any such changed law or regulation or compliance by
         the Bank with any such changed law or regulation after the Signing Date
         (including, without limitation, any law or regulation relating to
         taxation, any reserve, special deposit, cash ratio, liquidity or
         capital adequacy requirement or any form of banking or monetary control
         but excluding (i) changes arising from the implementation by any
         authority having jurisdiction over the Bank or its holding company of
         the matters set out in the statement prepared by the Basle Committee on
         Banking Regulations and Supervisory Practices dated July 1988 and
         entitled "International Convergence of Capital Measurement and Capital
         Standards" (as amended in November 1991) and (ii) changes arising from
         the implementation in whole or in part by any authority having
         jurisdiction over the Bank or its holding company of the proposals
         contained in the matters set out in the EC Directive 93/6/EEC of 15
         March 1993 on the capital adequacy of investment firms and credit
         institutions) is that the Bank incurs an increased cost, then the Bank
         will promptly notify the Company of the relevant event and the Company
         shall on demand pay to the Bank such amount as the Bank certifies in
         the demand will compensate it for the applicable increased cost.

13.2     In this Clause 13 "INCREASED COST" means:

         13.2.1   an additional cost incurred by the Bank as a result of it
                  having entered into, or performing, maintaining or funding its
                  obligations under, this Agreement; or

         13.2.2   that portion of an additional cost incurred by the Bank in
                  making, funding or maintaining all or any advances comprised
                  in a class of advances formed by or including the Advances
                  made or to be made by it under this Agreement as is
                  attributable to it making, funding, or maintaining such
                  advances; or

         13.2.3   a reduction in any amount payable to the Bank or the effective
                  return to the Bank under this Agreement or on its capital; or

         13.2.4   any payment made or interest or other return on or calculated
                  by reference to any amount received or receivable by the Bank
                  under this Agreement which is forgone.



                                      -21-
<PAGE>   22

13.3     When calculating an increased cost, the Bank may allocate or spread
         costs, liabilities and losses to or across its liabilities or assets,
         or any class of liabilities or assets, and on such basis, as it
         reasonably considers appropriate.

         INCREASED COSTS - EXCEPTIONS

13.4     An increased cost does not include any increased cost:

         13.4.1   compensated for by the payment of the Mandatory Cost;

         13.4.2   compensated for by the operation of Clause 11 (Taxes);

         13.4.3   attributable to any change in the rate of tax on the overall
                  net income of the Bank (or the overall net income of a
                  division or branch of the Bank) imposed in the jurisdiction in
                  which its principal office or the relevant lending office for
                  the time being is situate;

         13.4.4   payable to an assignee or transferee of the Bank at the time
                  of an assignment, transfer or novation under Clause 25
                  (Changes to the Parties), but only to the extent that the
                  increased cost would not have been payable to the assigning,
                  transferring or novating Bank; or

         13.4.5   which is attributable to the introduction of the euro other
                  than an increased cost which is being incurred generally by
                  banks transacting euro business in the London interbank
                  market.

14.      ILLEGALITY

14.1     If it is or becomes unlawful for the Bank to give effect to any of its
         obligations as contemplated by this Agreement or to fund or maintain
         any Advance, then the Bank shall notify the Company accordingly and on
         the Maturity Date of each relevant Advance (or such earlier date as the
         relevant law or directive may require) the relevant Borrower shall
         repay or prepay, as the case may be, any Advances made to it by the
         Bank together with all other amounts payable by it to the Bank under
         this Agreement.

14.2     The Bank's Commitment shall be cancelled on the date of a notification
         under Clause 14.1 above.

15.      TAXES AND INCREASED COSTS - ADDITIONAL RIGHTS

         PREPAYMENT AND CANCELLATIONS

15.1     If any Borrower is required to pay any additional amounts to the Bank
         under Clause 11 (Taxes) or compensation under Clause 13 (Increased
         Costs), the Company may, whilst the circumstances giving rise to the
         requirement continue, serve a notice of prepayment and cancellation in
         relation to all or all affected Advances on the Bank.

15.2     On the tenth Business Day after the date of service of the notice the
         relevant Borrower shall prepay the relevant Advance or Advances made to
         it by the



                                      -22-
<PAGE>   23


         Bank together with all other amounts in relation to such Advance(s)
         payable by it to the Bank under this Agreement.

15.3     To the extent of the Advances referred to in the notice of prepayment
         and cancellation, but not further or otherwise, the Bank's Commitment
         shall be cancelled on the date of service of the notice.

         MITIGATION

15.4     If, in respect of the Bank, circumstances arise which would or would,
         with the giving of notice, result in:

         15.4.1   any additional amounts becoming payable under Clause 11
                  (Taxes); or

         15.4.2   any increased cost becoming payable under Clause 13 (Increased
                  Costs); or

         15.4.3   any prepayment, payment or cancellation under Clause 14
                  (Illegality),

         then the Bank shall endeavour to take such steps as are reasonably open
         to it to mitigate or remove those circumstances (including seeking
         recovery for the account of the relevant Borrower where reasonably
         practicable and/or transferring its rights and obligations under this
         Agreement to another bank or financial institution acceptable to the
         Company).

15.5     Clause 15.4 above does not:

         15.5.1   prejudice the obligations of any Borrower under this Agreement
                  (including, without limitation, under the Clauses referred to
                  in Clause 15.4 above); or

         15.5.2   require the Bank to take any action which, in its opinion,
                  might be in any way prejudicial to it or conflict with its

                  made; and

         22.4.2   agrees as a primary obligation to indemnity the Bank from time
                  to time on demand by the Bank from and against any loss
                  incurred by the Bank as a result of any of the obligations of
                  each Borrower under or pursuant to this Agreement becoming
                  void, voidable, unenforceable or ineffective as against each
                  such Borrower for any reason whatsoever, whether or not known
                  to the Bank, the amount of

                  such loss being the amount which the person or persons
                  suffering it would otherwise have been entitled to recover
                  from any Borrower.

         PRESERVATION OF RIGHTS

22.5     The obligations of the Company contained in Clause 22.4 above (the
         "Obligations") shall be in addition to and independent of every other
         security which the Bank may at any time hold in respect of the
         obligations of the Borrowers under this Agreement.

22.6     The Obligations shall constitute and be continuing obligations
         notwithstanding any settlement of account or other matter or thing
         whatsoever, and in particular but without limitation, shall not be
         considered satisfied by any intermediate payment or satisfaction of all
         or any of the obligations of the Borrowers under this Agreement and
         shall continue in full force and effect until final payment in full of
         all amounts owing by the Borrowers thereunder and total satisfaction of
         all actual and contingent obligations thereunder.

22.7     Neither the Obligations nor the rights, powers and remedies conferred
         in respect of the Company in relation thereto upon the Bank by this
         Agreement or by law shall be discharged, impaired or otherwise affected
         by:

         22.7.1   the winding-up, dissolution, administration or re-organisation
                  of any Borrower or any other person or any change in its
                  status, function, control or ownership;

         22.7.2   any of the obligations of any Borrower or any other person
                  hereunder or under any other security taken in respect of any
                  of its obligations hereunder being or becoming illegal,
                  invalid, unenforceable or ineffective in any respect;

         22.7.3   time or other indulgence being granted or agreed to be granted
                  to any Borrower in respect of its obligations hereunder or
                  under any other security;

         22.7.4   any amendment, supplement or modification to, or any waiver of
                  or release of any obligation of any Borrower hereunder or
                  under any such other security;

         22.7.5   any failure to take, or fully to take, any security
                  contemplated hereby or otherwise agreed to be taken in respect
                  of any Borrower's obligations hereunder;

         22.7.6   any failure to realise or fully to realise the value of, or
                  any release, discharge, exchange or substitution of, any
                  security taken in respect of any Borrower's obligations
                  hereunder; or

         22.7.7   any other act, event or omission including, (without
                  limitation, any amendment to this Agreement) which, but for
                  this Clause 22.7 might operate to discharge, impair or
                  otherwise affect any of the obligations of the Borrowers or
                  the Company herein contained or any of the



                                      -33-

                  rights, powers or remedies conferred upon the Bank by this
                  Agreement or by law.

22.8     Any settlement or discharge between the Company and the Bank shall be
         conditional upon no security or payment to the Bank by any Borrower or
         any other person being avoided or reduced by virtue of any provisions
         or enactments relating to bankruptcy, insolvency, liquidation or
         similar laws of general application for the time being in force and, if
         any such security or payment is so avoided or reduced, the Bank shall
         be entitled to recover the value or amount of such security or payment
         from the Company subsequently as if such settlement or discharge had
         not occurred.

22.9     The Bank shall not be obliged before exercising any of the rights,
         powers or remedies conferred upon them in respect of the Borrowers or
         the Company by this Agreement or by law:

         22.9.1   to make any demand of any other Borrower;

         22.9.2   to take any action or obtain judgment in any court against any
                  other Borrower;

         22.9.3   to make or file any claim or proof in a winding-up or
                  dissolution of any Borrower; or

         22.9.4   to enforce or seek to enforce any other security taken in
                  respect of any of the obligations of any other Borrower
                  hereunder.

22.10    The Company agrees that, so long as any amounts are or may be owed by
         any Borrower hereunder or any Borrower is under any actual or
         contingent obligations hereunder, it shall not exercise any rights
         which it may at any time have by reason of performance by it of its
         obligations hereunder:

         22.10.1  to be indemnified by any other Borrower; and/or

         22.10.2  to claim any contribution from any other Borrower; and/or;

         22.10.3  to take the benefit (in whole or in part and whether by way of
                  subrogation or otherwise) of any rights of the Bank hereunder
                  or of any other security taken pursuant to, or in connection
                  with, this Agreement by the Bank; and/or

         22.10.4  to make or file any claim or proof in a winding-up or
                  dissolution of any other Borrower in connection with any
                  rights arising by reason of or in connection with the
                  performance by it of its obligations hereunder.

                  general law; and

         branch or currency of either obligation. If the obligations are in
         different currencies, the Bank may convert either obligation at the

29.      SEVERABILITY

31.      DESIGNATION OF ACCEDING AND SECEDING BORROWERS

31.1     The Company may request that any of its Subsidiaries incorporated in
         England and Wales and, with the prior written consent of the Bank (such
         consent not to be unreasonably withheld or delayed) any other
         Subsidiary of the Company becomes an Acceding Borrower by delivering or
         procuring the delivery to the Bank a Borrower's Accession Notice duly
         executed by the Company and the relevant Subsidiary provided that if
         such Subsidiary is not resident in the United Kingdom for tax purposes
         the Company and the Bank agree to make such amendments to this
         Agreement as may be reasonably required at the time in order to allow
         such Subsidiary to pay interest to the Bank without deduction or
         withholding of any Relevant Tax and to provide such Subsidiary with
         equivalent rights, mutatis mutandis, to those contained in Clause 11.4
         (Qualifying Bank).

31.2     Upon delivery of a Borrower's Accession Notice, the relevant Subsidiary
         shall become an Acceding Borrower and shall, subject to the terms and
         conditions of this Agreement acquire all the rights and assume all the
         obligations of a Borrower hereunder provided that the Bank has
         confirmed to the Company that it has received, in form and substance
         satisfactory to it, all the documents set out in Part II of Schedule 1.

31.3     The Company undertakes that it shall procure that each Acceding
         Borrower shall provide the Bank with each of the documents listed in
         Part II of Schedule 1.

31.4     If at any time any Borrower (other than the Company) has no actual or
         contingent obligation under this Agreement, the Company may deliver a
         Borrower's Cessation Notice to the Bank in which event such Borrower
         shall forthwith cease to be a Borrower upon receipt by the Bank of such
         notice.

32.      CHANGE OF CURRENCY

32.1     If more than one currency or currency unit are at the same time
         recognised by the central bank of any country as the lawful currency of
         that country, then:

         32.1.1   any reference in this Agreement to, and any obligations
                  arising under this Agreement in, the currency of that country
                  shall be translated into, or paid in, the currency unit of
                  that country designated by the Bank acting reasonably and in
                  consultation with the Company; and

         32.1.2   any translation from one currency unit to another shall be at
                  the official rate of exchange recognised by the relevant
                  central bank for the conversion of that currency or currency
                  unit into the other, rounded up or down by the Bank acting
                  reasonably.


                                      -38-
<PAGE>   39

32.2     If a change in any currency of a country occurs, the Bank and the
         Company will negotiate in good faith in order to agree any amendments
         to this Agreement to reflect market practice at that time with regard
         to the occurrence of EMU within the European Union or any part(s) of it
         and the new currency and to put the Bank and the Borrowers in the same
         position, so far as is possible, that they would have been in if no
         change in currency had occurred.

32.3     The Bank and the Company agree that the occurrence or non-occurrence of
         EMU within the European Union or part(s) of it and/or any event or
         events associated with EMU and/or the introduction of any new currency
         in all or any part of the European Union will not result in the
         discharge cancellation, rescission or termination in whole or in pat of
         this Agreement or give any party hereto the right to cancel, rescind,
         terminate or vary (other than as aforesaid) this Agreement in whole or
         in part or give rise to an Event of Default.

33.      COUNTERPARTS

         This Agreement may be executed in any number of counterparts each of
         which shall be an original and all of such counterparts taken together
         shall be delivered to constitute one and the same instrument.

34.      APPLICABLE LAW AND JURISDICTION

34.1     The law of England and Wales is the law applicable to this Agreement.

34.2     Each of the Borrowers irrevocably agrees for the benefit of the Bank
         that the courts of England shall have jurisdiction to hear and
         determine any suit, action or proceeding, and to settle any disputes,
         which may arise out of or in connection with this Agreement and, for
         such purposes, irrevocably submits to the jurisdiction of such courts.

34.3     Each of the Borrowers which is not incorporated in England and Wales
         agrees that the process by which any suit, action or proceeding is
         begun in England and Wales may be served on it by being delivered to
         the Company at its registered office for the time being and hereby
         appoints the Company (and the Company accepts such appointment) for
         such purposes. If the appointment of the person mentioned in this
         Clause 34.3 ceases to be effective in respect of any or all of the
         Borrowers such Borrower or Borrowers shall immediately appoint a
         further person in England and Wales to accept service of process on its
         behalf in England and Wales and, failing such appointment within
         fifteen days, the Bank acting reasonably shall be entitled to appoint
         such a person by notice to such Borrower or Borrowers. Nothing
         contained herein shall affect the right to serve process in any other
         manner permitted by law.

34.4     Each of the Borrowers irrevocably waives any objection which it might
         now or hereafter have to the courts referred to in Clause 34.2 being
         nominated as the forum to hear and determine any suit, action or
         proceeding, and to settle any disputes, which may arise out of or in
         connection with this Agreement and agrees not to claim that any such
         court is not a convenient or appropriate forum.

<PAGE>   40

34.5     The submission to the jurisdiction of the courts referred to in Clause
         34.2 shall not (and shall not be construed so as to) limit the right of
         the Bank to take proceedings against any of the Borrowers in any other
         court of competent jurisdiction nor shall the taking of proceedings in
         any one or more jurisdictions preclude the taking of proceedings in any
         other jurisdiction (whether concurrently or not) if and to the extent
         permitted by applicable law.

This Agreement has been entered into on the date stated at the beginning of this
Agreement.

2.2  The Bank may, at the Bank's sole option, make available to the Borrowers an
     acceptance credit facility under which the Bank shall, during the
     Availability Period and when requested by a Borrower, accept Bills drawn by
     such Borrower upon and subject to the terms of this Agreement.

     OVERALL FACILITY LIMIT

2.3  The aggregate Original Sterling Amount of all outstanding Utilisations
     shall not at any time exceed the Commitment at that time.

     NUMBER OF REQUESTS AND UTILISATIONS

2.4  Any number of Requests may be delivered on the same day and/or specifying
     the same Utilisation Date, whether or not the currencies and Terms
     requested are similar.

3.   PURPOSE

3.1  Each Borrower shall apply each Utilisation made to it towards the general
     corporate purposes of the Group.

3.2  Without affecting the obligations of any of the Borrowers in any way, the
     Bank shall not be bound to monitor or verify the application of the
     proceeds of any Utilisation.

4.   CONDITIONS PRECEDENT

     DOCUMENTARY CONDITIONS PRECEDENT

4.1  The obligations of the Bank to the Borrowers under this Agreement are
     subject to the condition precedent that the Bank has notified the Company
     that it has received, not later than 3 Business Days prior to the first
     Utilisation Date, all of the documents set out in Part I of Schedule 1 in
     form and substance satisfactory to the Bank.

     FURTHER CONDITIONS PRECEDENT

4.2  The obligation of the Bank to make each Utilisation is subject to the
     further conditions precedent that:

     4.2.1    on both the date of the Request and the Utilisation Date for that
              Utilisation:

              (a)  the representations and warranties in Clause 16
                   (Representations and Warranties) to be repeated on those
                   dates are correct and will be correct immediately after the
                   Utilisation; and

              (b)  no Default is outstanding or might result from the
                   Utilisation; and

                                      -10-
<PAGE>   11

     4.2.2    the Utilisation would not cause Clause 2.3 (Overall facility
              limit) to be contravened.

     4.2.3    in the case of the first Utilisation either:

              (a)  the total aggregate amounts outstanding under the Revolving
                   Multi-Currency Credit Facility and Acceptance Credit Facility
                   Agreement dated 14 May 1993 (as amended) made between the
                   Company and Den Danske Bank Aktieselskab the "Existing
                   Outstandings", shall have been repaid or prepaid in full and
                   the aggregate commitments under such facility agreement
                   cancelled on the day of such repayment or prepayment; or

              (b)  the amount of the first Utilisation together with other sums
                   available to the Borrower shall be used to repay or prepay
                   the Existing Outstandings and the aggregate commitments under
                   such facility agreement cancelled on the day of such
                   repayment or prepayment.

                   notice of Utilisation or delivery of that Request; or

              (d)  such other amounts as the Bank and the relevant Borrower may
                   agree;

     5.3.3    only one Term is specified which:

     of a Term of an optional duration becomes ineffective in accordance with
     sub-Clause 5.5.2.

5.5  If:

     5.5.1    the relevant Borrower requests a Term of an optional duration; and

     5.5.2    the Bank notifies such Borrower not later than 10.30 a.m. on the

              of Utilisation pursuant to Clause 5.1 or Clause 5.2 respectively
              that it does not agree to that request,

     the Term for the proposed Utilisation shall be the alternative period

     Request, the relevant Borrower must ensure that:

     5.8.1    the Utilisation Date is a Business Day;

     (Holding and Completion of Bills).

5.10 The Bank shall, as soon as is practicable but not later than 12.30 p.m. on

                                      -13-
<PAGE>   14

     HOLDING AND COMPLETION OF BILLS

5.11 The relevant Borrower shall ensure that the Bank has a sufficient stock of
     Bills, before giving a telephone notice of Utilisation or delivering any
     Request for a Utilisation comprising Bills.

5.12 Each Bill shall:

     5.12.1   be drawn by the relevant Borrower in its own favour and endorsed
              by it in blank;

     5.12.2   be undated;

     5.12.3   have the Maturity Date and the face amount left blank; and

     5.12.4   be claused in a manner which complies with the Bank of England's
              requirements for Eligible Bills at that time.

     DISCOUNTING OF BILLS

5.13 The Bank may arrange for a Bill accepted by it to be discounted on its
     behalf in the London discount market or elsewhere or discount the Bill
     itself.

     INFORMATION RELATING TO BILLS

5.14 The relevant Borrower shall, promptly on request, supply to the Bank any
     information relating to any Bill (including the underlying trade
     transaction for that Bill) as the Bank may reasonably require or which may
     be required by the Bank of England or any other fiscal or monetary
     authority in the UK.

     ELIGIBLE BILLS

5.15 The relevant Borrower shall ensure that each Bill drawn by it and accepted
     by the Bank is, assuming that the Bank is a bank whose acceptances are then
     being treated as eligible acceptances by the Bank of England, eligible for
     re-discounting at the Bank of England.

     PAYMENT OF PROCEEDS

5.16 Subject to the terms of this Agreement, the Bank shall pay to the relevant
     Borrower on the relevant Utilisation Date an amount equal to:

     5.16.1   the amount which the Bank receives or would receive as the
              proceeds of discounting if it had discounted the Bills accepted by
              it hereunder at the applicable EBDR; less

     5.16.2   acceptance commission calculated at the applicable Acceptance
              Commission Rate on the aggregate principal amount of those Bills.

<PAGE>   15

     NON-ACCEPTANCE OF BILLS

5.17 If the Bank gives the relevant Borrower notice under Clause 5.9 that the
     Bills referred to in the relevant telephone notice of Utilisation or
     Request will not be accepted by the Bank then, unless such Borrower, by
     notice to the Bank by 12.00 p.m. on the relevant Utilisation Date elects
     for the telephone notice of Utilisation or Request to be cancelled, without
     penalty, the said notice or Request shall be deemed to have been a request
     for an Advance of an amount equal to the Requested Amount and for a Term
     equal to the Term specified in the telephone notice or Request (or if the
     Bank does not agree to that Term then for a Term of 3 months) to be made
     available to such Borrower on such Utilisation Date.

     STANDARD OF CARE

5.18 In holding and dealing with Bills delivered to it under this Clause, the
     Bank shall use the same standard of care as it uses in holding and dealing
     with its own notes, bills or certificates of deposit and shall indemnify
     the relevant Borrower for any failure so to do. If the Commitment has been
     reduced to zero the Bank shall forthwith destroy all uncompleted Bills held
     by it and shall provide to the Company a certificate of destruction in
     respect thereof.

6.   CANCELLATION AND EXTENSION

     AUTOMATIC CANCELLATION OF THE COMMITMENT

6.1  The Commitment shall be automatically cancelled at close of business on the
     Availability Period End Date.

     VOLUNTARY CANCELLATION

6.2  The Company may, without penalty and by giving not less than 15 days' prior
     notice to the Bank, cancel the Commitment in whole or in part.

6.3  A notice of cancellation will be irrevocable and shall specify:

     6.3.1    the date on which the cancellation is to become effective; and

     6.3.2    the amount of the Commitment to be cancelled.

6.4  Any cancellation may only take effect in respect of the unutilised portion
     of the Commitment as at the date the notice is to be effective.

     NO REINSTATEMENT

6.5  No amount of the Commitment cancelled under this Agreement may subsequently
     be reinstated.

                                      -15-
<PAGE>   16

     EXTENSION

6.6  Not more 30 days but not less than 5 days prior to the Availability Period
     End Date the Company may request that the Bank extend the Acceptance Credit
     Facility and/or the Loan Facility for a further period of 364 days. Any
     such request shall be irrevocable and in writing. The Bank shall have
     absolute discretion as to whether to agree to such an extension, and the
     Bank shall advise the Company in writing of its decision as soon as
     reasonably practicable, and in any event, not less than 3 days prior to the
     Availability Period End Date. If the Bank agrees to such extension the
     Acceptance Credit Facility and/or the Loan Facility shall be extended so
     that the Availability Period End Date becomes the day 364 days after the
     Availability Period End Date prior to such extension.

7.   INTEREST

     INTEREST RATE

7.1  The rate of interest on each Advance for its Term is the rate per annum
     determined by the Bank to be the aggregate of the applicable:

     7.1.1    Margin,

     7.1.2    LIBOR; and

     7.1.3    Mandatory Costs.

     DUE DATES

7.2  Except as otherwise provided in this Agreement, accrued interest on each
     Advance is payable on its Maturity Date and also, in the case of an Advance
     with a term longer than six months, on the date falling six months after
     its Utilisation Date.

     DEFAULT INTEREST

7.3  If any Borrower fails to pay any amount payable by it under this Agreement,
     it shall, on demand by the Bank from time to time, pay interest on the
     overdue amount from the due date up to the date of actual payment, after as
     well as before judgment, at a rate (the "DEFAULT RATE") determined by the
     Bank to be one (1) per cent. per annum above the higher of:

     7.3.1    the rate on the overdue amount under Clause 7.1 (Interest rate)
              immediately before the due date (but only if the overdue amount is
              an Advance (or part thereof) and only for the period up to and
              including the Maturity Date of that Advance); and

     7.3.2    the rate which would have been payable if the overdue amount had,
              during the period of non-payment, constituted an Advance in the
              currency of the overdue

                                      -16-
<PAGE>   17
              amount for such successive Terms of such duration (not exceeding
              three months) as the Bank may reasonably determine (each a
              "DESIGNATED TERM").

7.4  The default rate will be determined on the first day of, or two Business
     Days before the first day of, the relevant Designated Term, as appropriate.

7.5  If the Bank determines that deposits in the currency of the overdue amount
     are not at the relevant time being made available by leading banks in the
     London Interbank Market, the default rate will be determined by reference
     to the cost of funds to the Bank from whatever sources it may reasonably
     select.

7.6  Default interest shall be compounded at the end of each Designated Term
     until it is paid.

     NOTIFICATION OF RATES OF INTEREST

7.7  The Bank shall promptly notify the relevant Borrower of the determination
     of any applicable rate of interest under this Agreement.

8.   REPAYMENT AND PREPAYMENT

     PAYMENT OF BILLS

8.1  Each Borrower shall pay to the Bank an amount equal to the principal amount
     of each of its Bills accepted by the Bank on the Maturity Date for each
     such Bill.

     REPAYMENT OF ADVANCES

8.2  Each Borrower shall repay each Advance made to it in full on its Maturity
     Date to the Bank. If an Advance (the "NEW ADVANCE") is to be made to a
     Borrower on the day on which another Advance (the "MATURING ADVANCE") in
     the same currency is due to be repaid by such Borrower then, subject to the
     terms of this Agreement and so long as the conditions referred to in Clause
     4.2 shall have been satisfied in relation to the New Advance:

     8.2.1    the Maturing Advance shall be deemed to have been repaid on its
              Maturity Date either in whole (if the New Advance is equal to or
              greater than the Maturing Advance) or in part (if the New Advance
              is less than the Maturing Advance); and

     8.2.2    to the extent that a Maturing Advance is so deemed to have been
              repaid, the principal amount of the New Advance to be made on such
              a date shall be deemed to have been credited to the account of
              such Borrower by the Bank in accordance with the terms of this
              Agreement and, as the case may be:

              (a)  the Bank shall only be obliged to make available to such
                   Borrower pursuant to Clause 5.6 a principal amount equal to
                   the amount (if any) by which the New Advance exceeds the
                   Maturing Advance; or

                                      -17-
<PAGE>   18

              (b)  such Borrower shall only be obliged to pay to the Bank
                   pursuant to this Clause 8.2 a principal amount equal to the
                   amount by which the Maturing Advance exceeds the New Advance.

8.3  On the Availability Period End Date, all outstanding Utilisations and other
     sums (if any) then owing under this Agreement shall in any event be repaid
     or paid in full.

     PREPAYMENT OF BILLS

8.4  Any Borrower may, by giving not less than 15 days' prior notice to the
     Bank, prematurely comply with its obligations under Clause 8.1 (Payment of
     Bills).

8.5  If, under the terms of this Agreement, including without limitation this
     Clause 8 and Clauses 14.1.2 and 15.2.2, a Borrower prematurely complies
     with its obligations under Clause 8.1 (Payment of Bills) in respect of any
     Bill, then the amount payable by such Borrower shall be the principal
     amount equal to the Bill discounted on the basis of such normal commercial
     rates prevailing at the time of payment for Sterling deposits of an amount
     equal to the amount so paid for the period from the time of payment to the
     Maturity Date of the Bill as the Bank may reasonably determine. If and to
     the extent that a Borrower pays more than it is obliged to pay under this
     Clause then the Bank shall pay to such Borrower an amount equal to such
     over-payment by no later than the Maturity Date of the relevant Bill.

     PREPAYMENT OF ADVANCES

8.6  Any Borrower may, without penalty and on giving not less than 15 days'
     prior notice to the Bank, prepay all or any part of an Advance, but if in
     part, in a minimum amount of Pound Sterling 1,000,000 and an integral
     multiple of Pound Sterling 100,000 (or the comparable amount in any
     Optional Currency).

8.7  Any notice by a Borrower of prepayment under this Agreement is irrevocable.

8.8  Should any person or group of persons, acting either individually or in
     concert (as defined in the City Code on Take Overs and Mergers effective as
     at the date of this Agreement) otherwise than with the consent of the Bank
     acquire control of the Company (and for the purpose of this Clause a single
     person or group of persons shall have acquired control if it or they own or
     hold more than 50% (fifty per cent.) of the issued share capital of the
     Company having the right to attend and vote at general meetings of the
     Company or more than 50% (fifty per cent.) of such rights), then:

     8.8.1    the Company shall immediately upon becoming aware thereof notify
              the Bank specifying the date of such acquisition and the name of
              such person or persons acquiring control; and

     8.8.2    thereafter no Borrower shall be permitted to request a Utilisation
              unless the terms of the acquisition of control of the Company were
              approved by the Board of Directors of the Company and the Maturity
              Date for any Utilisation requested

                                      -18-
<PAGE>   19

              falls on a date not more than three months after the expiration of
              the 30 day period referred to in Clause 8.9.

8.9  If the terms of the acquisition of control of the Company were approved by
     the Board of Directors of the Company, the Bank shall consult with the
     Company during the period of 30 days after receipt of the notification from
     the Company referred to in sub-Clause 8.8.1 and shall be entitled to give a
     notice of continuance of each Facility to the Company. Upon receipt of such
     notice of continuance, the right of the Borrowers to request a Utilisation
     without the limitation referred to in sub-Clause 8.8.2 shall be reinstated.

8.10 If the terms of the acquisition of control of the Company were approved by
     the Board of Directors of the Company but, at the end of the period of 30
     days referred to in Clause 8.9 above, the Company has not received a notice
     of continuance then:

     8.10.1   the Acceptance Credit Facility and the Loan Facility shall be
              cancelled;

     8.10.2   any outstanding Utilisations with Maturity Dates falling later
              than three months after the end of such period shall be prepaid on
              the date falling three months after the end of such period,
              together with accrued interest thereon up to the date of payment
              and all other amounts payable to the Bank hereunder; and

     8.10.3   any outstanding Utilisations with Maturity Dates falling not later
              than three months after the end of such period shall be repaid on
              their respective Maturity Dates.

10.  OPTIONAL CURRENCIES

     SELECTION

10.1 No Borrower may request an Advance denominated in an Optional Currency
     unless the Bank has confirmed to such Borrower that the Optional Currency
     is readily available and freely transferable in the London foreign exchange
     market.

     CHANGE OF CURRENCY

10.2 If, on the Rate Fixing Day of an Advance to be denominated in an Optional
     Currency, the Bank determines that:

     10.2.1   it is impracticable for reasons beyond its control for the Bank to
              fund the Advance for its Term in that Optional Currency in the
              ordinary course of business in the London Interbank Market; or

     10.2.2   the use of the proposed Optional Currency might contravene any law
              or regulation,

                                      -21-
<PAGE>   22

              then:

     10.2.3   the Bank shall promptly and in any event before 10.30 a.m. on that
              Rate Fixing Day notify the relevant Borrower;

     10.2.4   if the Bank receives notice from the relevant Borrower by 11.30
              a.m. on that Rate Fixing Day to that effect, the Advance will not
              be made; and

     10.2.5   if the Bank does not receive any notice under sub-Clause 10.2.4
              above, the Advance will be denominated instead in Sterling in an
              amount equal to its Original Sterling Amount.

     NOTIFICATION OF RATES AND AMOUNTS

10.3 The Bank shall, on request, promptly notify the relevant Borrower of any
     applicable Bank's Spot Rate of Exchange or Original Sterling Amount
     promptly after it has been ascertained.

10.4 If an Advance which has been drawn in an Optional Currency is reborrowed in
     the same Optional Currency immediately following its repayment, then the
     Original Sterling Amount of such new Advance denominated in such Optional
     Currency shall be recalculated for the new Term in accordance with the
     terms and conditions of this Agreement and if on the relevant Utilisation
     Date the aggregate Original Sterling Amount of all Utilisations outstanding
     on such date exceeds the Commitment, then any excess shall be repaid to the
     Bank by the relevant Borrower upon the Bank's first written demand.

11.  TAXES

     GROSS-UP

11.1 All payments by each of the Borrowers under this Agreement shall be made
     without any deductions and free and clear of and without deduction for or
     on account of any Relevant Taxes except to the extent that any Borrower is
     required by law to make payment subject to any such taxes. If any Relevant
     Tax or amounts in respect of any Relevant Tax must be deducted from any
     amounts payable or paid by any Borrower hereunder, such Borrower shall pay
     such additional amounts as may be necessary to ensure that the Bank
     receives a net amount equal to the full amount which it would have received
     had payment not been made subject to tax.

     "RELEVANT TAX" in relation to any payment which falls to be made hereunder
     means any present or future taxes of any nature now or hereafter imposed by
     the laws of (i) the United Kingdom, (ii) any other jurisdiction from which,
     or through which, such payment is made or to the taxation laws of which the
     relevant Borrower is at the time of such payment subject, (iii) any
     political sub-division of the United Kingdom or any such other jurisdiction
     or (iv) any federation or association of states of which the United Kingdom
     or any such other jurisdiction is, at the time of such payment, a member.

                                      -22-
<PAGE>   23

     TAX RECEIPTS

11.2 All Relevant Taxes required by law to be deducted or withheld by any
     Borrower from any amount paid or payable under this Agreement shall be paid
     by such Borrower when due (unless the obligation to pay is being disputed
     in good faith) and such Borrower shall, within 30 days of the payment being
     made, deliver to the Bank evidence satisfactory to the Bank (including all
     relevant tax receipts) that the payment has been duly remitted to the
     appropriate authority.

     TAX CREDITS

11.3 If any Borrower pays any additional amount (a "TAX PAYMENT") under Clause
     11.1 and the Bank effectively obtains a refund of tax, or a relief or
     credit against tax by reason of that Tax Payment (a "TAX CREDIT"), and the
     Bank is able to identify the Tax Credit as being attributable to the Tax
     Payment, then the Bank shall reimburse to the relevant Borrower such amount
     as the Bank reasonably determines to be the proportion of the Tax Credit as
     will leave the Bank (after that reimbursement) in no better or worse
     position that it would have been if the Tax Payment had not been required.
     Nothing in this Clause interferes with the right of the Bank to arrange its
     tax affairs in whatever manner it thinks fit and, without prejudice to the
     foregoing, the Bank is under no obligation to claim a Tax Credit, or to
     claim a Tax Credit in priority to any other claim, relief, credit or
     deduction available to it. The Bank is not obliged to disclose any
     information regarding its tax affairs or computations to any Borrower.

     QUALIFYING BANK

11.4 If, otherwise than as a result of the introduction of, change in, or change
     in the interpretation, administration or application of, any law or
     regulation or any practice or concession of the Inland Revenue after the
     Signing Date, the Bank ceases to be a Qualifying Bank no Borrower shall be
     liable to pay to the Bank under Clause 11.1 (Gross-up) any amount in
     respect of taxes levied or imposed by the UK or any taxing authority
     thereof or therein in excess of the amount it would have been obliged to
     pay if the Bank had been or had not ceased to be a Qualifying Bank.

12.  MARKET DISRUPTION

     MARKET DISRUPTION - ADVANCES

12.1 If, in relation to any proposed Utilisation comprising Advances:

     12.1.1   the Bank is unable to obtain from leading banks a rate for the
              purposes of determining the applicable LIBOR or the Bank otherwise
              determines that adequate and fair means do not exist for
              ascertaining the applicable LIBOR; or

     12.1.2   in the opinion of the Bank:

                                      -23-
<PAGE>   24

              (a)  matching deposits may not be available to it in the London
                   Interbank Market in the ordinary course of business to fund
                   an Advance; or

              (b)  the cost to it of matching deposits in the London Interbank
                   Market would be in excess of the relevant LIBOR,

     the Bank shall notify the Company by 10.30 a.m. or as soon as is
     practicable thereafter on the Rate Fixing Day of the fact and that this
     Clause is in operation.

12.2 After any notification under Clause 12.1. above:

     12.2.1   subject to sub-Clause 12.2.3 below the relevant Advance shall be
              made in Sterling in an amount equal to its Original Sterling
              Amount (unless Sterling was the original currency of the relevant
              Advance);

     12.2.2   subject to sub-Clause 12.2.3 below, no further notices of
              Utilisation by telephone or Requests for Advances to be
              denominated in the original currency of the affected Advance may
              be delivered until the Bank notifies the Company that the event
              specified in the notification no longer prevails;

     12.2.3   the relevant Borrower may, by notice to the Bank by 11.00 a.m.
              (or, if later, within 30 minutes of receipt by the Company of a
              notification under Clause 12.1) on the Rate Fixing Day: (i) elect
              for the notice of Utilisation by telephone or Request to be
              cancelled without penalty; (ii) if the Advance was to be made in
              an Optional Currency, elect for the Advance to be made in an
              Optional Currency other than a currency affected by the event
              specified in the notification or (iii) elect for the Advance to be
              made in accordance with the Request notwithstanding the event
              specified in the notification. If any Borrower requires an
              affected Advance to be made in the original currency selected for
              such Advance notwithstanding the event specified in the
              notification then within five Business Days of receipt of the
              notification, the Company and the Bank shall enter into
              negotiations for a period of not more than 25 days with a view to
              agreeing a substitute basis for determining the rate of interest
              and/or funding applicable to the affected Advance and any future
              Advances in the currency of the affected Advance provided that if
              no substitute basis is agreed within that period:

              (a)  the Bank shall certify to the Company (such certificate to be
                   conclusive) the alternative interest rate calculated in
                   accordance with sub-Clause 12.2.4 below;

              (b)  the certificate may make provision for different funding
                   periods and shall be retroactive to the beginning of the then
                   current Term; and

              (c)  the certificate shall be binding on each relevant Borrower
                   unless the Company gives notice to the Bank within five
                   Business Days of the receipt of the certificate that the
                   certificate is not acceptable and that each relevant Borrower
                   shall prepay in full the relevant Advances on a Business Day
                   specified in the notice, which shall be not less than five

                                      -24-
<PAGE>   25

                   nor more than thirty days after the date of the Bank's
                   certificate to the Company; and

     12.2.4   for the purposes of sub-Clause 12.2.3(a) above the rate of
              interest on each Advance shall be the rate certified by the Bank
              as the rate per annum determined by the Bank to be the aggregate
              of:

                   (i)   the Margin;

                   (ii)  the rate notified by the Bank, on or before the last
                         day of its Term, as being the cost to the Bank of
                         funding the Advance from such other sources as it may
                         reasonably select; and

                   (iii) the applicable Mandatory Cost if any.

12.3 During the period when any substitute basis is in force in relation to a
     particular currency, the Bank shall periodically determine whether the
     circumstances referred to in Clause 12.1 above still apply and, if they do
     not, shall forthwith give notice in writing to the Company of the date on
     which the substitute basis will cease to apply.

     MARKET DISRUPTION - BILLS

12.4 If, in relation to any Bills:

     12.4.1   the Bank, acting reasonably, determines that adequate and fair
              means do not exist for determining the applicable EBDR; or

     12.4.2   the Bank, acting reasonably, determines that the Bills do not
              comply with the then current Bank of England regulations for
              Sterling bankers' acceptances

     the Bank shall notify the Company by 12.00 p.m. on the Utilisation Date of
     the fact and that this Clause is in operation.

12.5 After any notification under Clause 12.4 above:

     12.5.1   those Bills shall not be accepted;

     12.5.2   in the case of Clause 12.4.1, no further Requests for Bills may be
              delivered until the Bank notifies the Company that it is once
              again able to determine EBDR; and

     12.5.3   unless the relevant Borrower, by notice to the Bank by 12.30 p.m.
              on the relevant Utilisation Date, elects for the telephone notice
              of Utilisation or Request for Bills to be cancelled without
              penalty, the said notice or Request shall be deemed to have been a
              request for an Advance of an amount equal to the Requested Amount
              and for a Term equal to the Term specified in the telephone notice
              or Request (or if the Bank does not agree to that Term, then for a
              Term of 3 months) to be made available to such Borrower on such
              Utilisation Date.

13.  INCREASED COSTS

     INCREASED COSTS - SERVICE OF DEMAND

13.1 If the result of any introduction of or change in any law or regulation
     after the Signing Date, or of any change in the application or
     interpretation of any such changed law or regulation or compliance by the
     Bank with any such changed law or regulation after the Signing Date
     (including, without limitation, any law or regulation relating to taxation,
     any reserve, special deposit, cash ratio, liquidity or capital adequacy
     requirement or any form of banking or monetary control but excluding (i)
     changes arising from the implementation by any authority having
     jurisdiction over the Bank or its holding company of the matters set out in
     the statement prepared by the Basle Committee on Banking Regulations and
     Supervisory Practices dated July 1988 and entitled "International
     Convergence of Capital Measurement and Capital Standards" (as amended in
     November 1991) and (ii) changes arising from the implementation in whole or
     in part by any authority having jurisdiction over the Bank or its holding
     company of the proposals contained in the matters set out in the EC
     Directive 93/6/EEC of 15 March 1993 on the capital adequacy of investment
     firms and credit institutions) is that the Bank incurs an increased cost,
     then the Bank will promptly notify the Company of the relevant event and
     the Company shall on demand pay to the Bank such amount as the Bank
     certifies in the demand will compensate it for the applicable increased
     cost.

13.2 In this Clause 13 "INCREASED COST" means:

     13.2.1   an additional cost incurred by the Bank as a result of it having
              entered into, or performing, maintaining or funding its
              obligations under, this Agreement; or

     13.2.2   that portion of an additional cost incurred by the Bank in making,
              funding or maintaining all or any advances comprised in a class of
              advances formed by or including the Advances made or to be made by
              it under this Agreement as is attributable to it making, funding,
              or maintaining such advances; or

     13.2.3   a reduction in any amount payable to the Bank or the effective
              return to the Bank under this Agreement or on its capital; or

     13.2.4   any payment made or interest or other return on or calculated by
              reference to any amount received or receivable by the Bank under
              this Agreement which is forgone.

13.3 When calculating an increased cost, the Bank may allocate or spread costs,
     liabilities and losses to or across its liabilities or assets, or any class
     of liabilities or assets, and on such basis, as it reasonably considers
     appropriate.

     INCREASED COSTS - EXCEPTIONS

13.4 An increased cost does not include any increased cost:

     13.4.1   compensated for by the payment of the Mandatory Cost;

                                      -26-
<PAGE>   27

     13.4.2   compensated for by the operation of Clause 11 (Taxes);

     13.4.3   attributable to any change in the rate of tax on the overall net
              income of the Bank (or the overall net income of a division or
              branch of the Bank) imposed in the jurisdiction in which its
              principal office or the relevant lending office for the time being
              is situate;

     13.4.4   payable to an assignee or transferee of the Bank at the time of an
              assignment, transfer or novation under Clause 25 (Changes to the
              Parties), but only to the extent that the increased cost would not
              have been payable to the assigning, transferring or novating Bank;
              or

     13.4.5   which is attributable to the introduction of the euro other than
              an increased cost which is being incurred generally by banks
              transacting euro business in the London interbank market.

14.  ILLEGALITY

14.1 If it is or becomes unlawful for the Bank to give effect to any of its
     obligations as contemplated by this Agreement or to fund or maintain any
     Utilisation, then the Bank shall notify the Company accordingly and on the
     Maturity Date of each relevant Utilisation (or such earlier date as the
     relevant law or directive may require):-

     14.1.1   the relevant Borrower shall repay or prepay, as the case may be,
              any Advances made to it by the Bank together with all other
              amounts payable by it to the Bank under this Agreement; and

     14.1.2   the Company's obligations under Clause 8.1 (Payment of Bills) in
              respect of Bills accepted by the Bank shall immediately become due
              for performance and the Company shall immediately perform those
              obligations.

14.2 The Bank's Commitment shall be cancelled on the date of a notification
     under Clause 14.1 above.

15.  TAXES AND INCREASED COSTS - ADDITIONAL RIGHTS

     PREPAYMENT AND CANCELLATIONS

15.1 If any Borrower is required to pay any additional amounts to the Bank under
     Clause 11 (Taxes) or compensation under Clause 13 (Increased Costs), the
     Company may, whilst the circumstances giving rise to the requirement
     continue, serve a notice of prepayment and cancellation in relation to all
     or all affected Advances and Bills on the Bank.

15.2 On the tenth Business Day after the date of service of the notice:

              and

     15.2.2   each Borrower's obligations under Clause 8.1 (Payment of Bills) in

              circumstances (including seeking recovery for the account of the
              relevant Borrower where reasonably practicable and/or transferring

               pay any amount under this Agreement in a currency other than that
               in which it is expressed to be payable.

      PRESERVATION OF RIGHTS

22.5  The obligations of the Company contained in Clause 22.4 above (the

      security which the Bank may at any time hold in respect of the obligations
      of the Borrowers under this Agreement.

22.6  The Obligations shall constitute and be continuing obligations
      notwithstanding any settlement of account or other matter or thing

      any of the obligations of the Borrowers under this Agreement and shall

      amounts owing by the Borrowers thereunder and total satisfaction of all
      actual and contingent obligations thereunder.

      respect of the Company in relation thereto upon the Bank by this Agreement
      or by law shall be discharged, impaired or otherwise affected by:

      22.7.1   the winding-up, dissolution, administration or re-organisation of

               unenforceable or ineffective in any respect;

      22.7.3   time or other indulgence being granted or agreed to be granted to

      22.7.5   any failure to take, or fully to take, any security contemplated

      22.7.7   any other act, event or omission including, (without limitation,
               any amendment to this Agreement) which, but for this Clause 22.7
               might operate to discharge, impair or otherwise affect any of the
               obligations of the Borrowers or the Company herein contained or
               any of the rights, powers or remedies conferred upon the Bank by
               this Agreement or by law.

22.8  Any settlement or discharge between the Company and the Bank shall be
      conditional upon no security or payment to the Bank by any Borrower or any
      other person being avoided or reduced by virtue of any provisions or
      enactments relating to bankruptcy, insolvency, liquidation or similar laws
      of general application for the time being in force and, if any such
      security or payment is so avoided or reduced, the Bank shall be entitled
      to recover the value or amount of such security or payment from the
      Company subsequently as if such settlement or discharge had not occurred.

              of any of the obligations of any other Borrower hereunder.

22.10 The Company agrees that, so long as any amounts are or may be owed by any
      Borrower hereunder or any Borrower is under any actual or contingent
      obligations hereunder, it shall not exercise any rights which it may at
      any time have by reason of performance by it of its obligations hereunder:

      22.10.1  to be indemnified by any other Borrower; and/or

      22.10.2  to claim any contribution from any other Borrower; and/or;

      22.10.3  to take the benefit (in whole or in part and whether by way of
               subrogation or otherwise) of any rights of the Bank hereunder or
               of any other security taken pursuant to, or in connection with,
               this Agreement by the Bank; and/or

      22.10.4  to make or file any claim or proof in a winding-up or dissolution
               of any other Borrower in connection with any rights arising by
               reason of or in connection with the performance by it of its
               obligations hereunder.

31.   DESIGNATION OF ACCEDING AND SECEDING BORROWERS

31.1  The Company may request that any of its Subsidiaries incorporated in
      England and Wales and, with the prior written consent of the Bank (such
      consent not to be unreasonably withheld or delayed) any other Subsidiary
      of the Company becomes an Acceding Borrower by delivering or procuring the
      delivery to the Bank a Borrower's Accession Notice duly executed by the
      Company and the relevant Subsidiary provided that if such Subsidiary is
      not resident in the United Kingdom for tax purposes the Company and the
      Bank agree to make such amendments to this Agreement as may be reasonably
      required at the time in order to allow such Subsidiary to pay interest to
      the Bank without deduction or withholding of any Relevant Tax and to
      provide such Subsidiary with equivalent rights, mutatis mutandis, to those
      contained in Clause 11.4 (Qualifying Bank).

31.2  Upon delivery of a Borrower's Accession Notice, the relevant Subsidiary
      shall become an Acceding Borrower and shall, subject to the terms and
      conditions of this Agreement acquire all the rights and assume all the
      obligations of a Borrower hereunder provided that the Bank has confirmed
      to the Company that it has received, in form and substance satisfactory to
      it, all the documents set out in Part II of Schedule 1.

31.3  The Company undertakes that it shall procure that each Acceding Borrower
      shall provide the Bank with each of the documents listed in Part II of
      Schedule 1.

31.4  If at any time any Borrower (other than the Company) has no actual or
      contingent obligations under this Agreement, the Company may deliver a
      Borrower's Cessation Notice to the Bank in which event such Borrower shall
      forthwith cease to be a Borrower upon receipt by the Bank of such notice.

32.   CHANGE OF CURRENCY

32.1  If more than one currency or currency unit are at the same time recognised
      by the central bank of any country as the lawful currency of that country,
      then:

      32.1.1   any reference in this Agreement to, and any obligations arising
               under this Agreement in, the currency of that country shall be
               translated into, or paid in, the currency unit of that country
               designated by the Bank acting reasonably and in consultation with
               the Company; and

                                      -44-
<PAGE>   45

      32.1.2   any translation from one currency unit to another shall be at the
               official rate of exchange recognised by the relevant central bank
               for the conversion of that currency or currency unit into the
               other, rounded up or down by the Bank acting reasonably.

32.2  If a change in any currency of a country occurs, the Bank and the Company
      will negotiate in good faith in order to agree any amendments to this
      Agreement to reflect market practice at that time with regard to the
      occurrence of EMU within the European Union or any part(s) of it and the
      new currency and to put the Bank and the Borrowers in the same position,
      so far as is possible, that they would have been in if no change in
      currency had occurred.

32.3  The Bank and the Company agree that the occurrence or non-occurrence of
      EMU within the European Union or part(s) of it and/or any event or events
      associated with EMU and/or the introduction of any new currency in all or
      any part of the European Union will not result in the discharge
      cancellation, rescission or termination in whole or in part of this
      Agreement or give any party hereto the right to cancel, rescind, terminate
      or vary (other than as aforesaid) this Agreement in whole or in part or
      give rise to an Event of Default.

33.   COUNTERPARTS

33.1  This Agreement may be executed in any number of counterparts each of which
      shall be an original and all of such counterparts taken together shall be
      delivered to constitute one and the same instrument.

34.   APPLICABLE LAW AND JURISDICTION

34.1  The law of England and Wales is the law applicable to this Agreement.

34.2  Each of the Borrowers irrevocably agrees for the benefit of the Bank that
      the courts of England shall have jurisdiction to hear and determine any
      suit, action or proceeding, and to settle any disputes, which may arise
      out of or in connection with this Agreement and, for such purposes,
      irrevocably submits to the jurisdiction of such courts.

34.3  Each of the Borrowers which is not incorporated in England and Wales
      agrees that the process by which any suit, action or proceeding is begun
      in England and Wales may be served on it by being delivered to the Company
      at its registered office for the time being and hereby appoints the
      Company (and the Company accepts such appointment) for such purposes. If
      the appointment of the person mentioned in this Clause 34.3 ceases to be
      effective in respect of any or all of the Borrowers such Borrower or
      Borrowers shall immediately appoint a further person in England and Wales
      to accept service of process on its behalf in England and Wales and,
      failing such appointment within fifteen days, the Bank acting reasonably
      shall be entitled to appoint such a person by notice to such Borrower or
      Borrowers. Nothing contained herein shall affect the right to serve
      process in any other manner permitted by law.

                                      -45-
<PAGE>   46

34.4  Each of the Borrowers irrevocably waives any objection which it might now
      or hereafter have to the courts referred to in Clause 34.2 being nominated
      as the forum to hear and determine any suit, action or proceeding, and to
      settle any disputes, which may arise out of or in connection with this
      Agreement and agrees not to claim that any such court is not a convenient
      or appropriate forum.

34.5  The submission to the jurisdiction of the courts referred to in Clause
      34.2 shall not (and shall not be construed so as to) limit the right of
      the Bank to take proceedings against any of the Borrowers in any other
      court of competent jurisdiction nor shall the taking of proceedings in any
      one or more jurisdictions preclude the taking of proceedings in any other
      jurisdiction (whether concurrently or not) if and to the extent permitted
      by applicable law.

      This  Agreement has been entered into on the date stated at the beginning
      of this Agreement.

                          AGREEMENT AND PLAN OF MERGER

         AGREEMENT AND PLAN OF MERGER (this "Agreement"), dated as of July 28,
1999, by and among Caradon Inc., a Delaware corporation ("Parent"), E Acqco
Inc., a Delaware corporation and an indirect wholly owned subsidiary of Parent
("Purchaser"), and Easco, Inc., a Delaware corporation (the "Company").

         WHEREAS, each of the boards of directors of Parent, Purchaser and the
Company has approved, and deems it advisable and in the best interests of its
respective stockholders to consummate, the acquisition of the Company by Parent
upon the terms and subject to the conditions set forth herein;

         WHEREAS, in furtherance thereof, it is proposed that Purchaser will
make a tender offer (the "Offer") to acquire any and all shares (the "Shares")
of the issued and outstanding common stock, $.01 par value (the "Common Stock"),
of the Company for $15.20 per Share, net to the seller in cash (such amount, or
any higher price per Share as may be paid in the Offer, the "Offer Price");

         WHEREAS, in furtherance of such acquisition, the boards of directors of
the Company, Parent and Purchaser each have approved the Merger (as defined
herein) following the Offer in accordance with the General Corporation Law of
the State of Delaware ("Delaware Law") and upon the terms and subject to the
condition set forth herein;

         WHEREAS, the board of directors of the Company (the "Board of
Directors") has determined that the consideration to be paid for each Share in
the Offer and the Merger and the transactions contemplated thereby are fair to
the holders of such Shares and has recommended to the Board of Directors that it
approve and adopt this Agreement and the transactions contemplated hereby and
recommend that the holders of such Shares accept the Offer and approve and adopt
this Agreement and each of the transactions contemplated hereby upon the terms
and subject to the conditions set forth herein, and the Board of Directors has
unanimously so resolved to recommend;

         WHEREAS, as a condition to Parent's willingness to enter into this
Agreement, Parent and certain stockholders of the Company, which beneficially
own approximately 46% of the outstanding Shares, are simultaneously entering
into stockholder agreements, dated the date hereof, pursuant to which such
stockholders have irrevocably agreed, among other things, to tender all of the
Shares owned by them in the Offer (the "Stockholder Agreement"); and

         WHEREAS, the Company, Parent and Purchaser desire to make certain
representations, warranties, covenants and agreements in connection with the
Offer and Merger.

<PAGE>   8
         NOW, THEREFORE, in consideration of the foregoing and the mutual
representation, warranties, covenants and agreements set forth herein, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:

                                    ARTICLE I

                              THE OFFER AND MERGER

         Section 1.1    The Offer.

              (a)       Provided that this Agreement shall not have been
terminated in accordance with Section 8.1 and none of the events set forth in
Annex A shall have occurred and are existing, as promptly as practicable (but in
no event later than five business days after the public announcement of the
execution of this Agreement), Purchaser shall commence (within the meaning of
Rule 14d-2 under the Securities Exchange Act of 1934, as amended (the "Exchange
Act")) the Offer at the Offer Price and, subject to there being validly tendered
and not properly withdrawn prior to the expiration of the Offer that number of
Shares which represents at least a majority of the Shares then outstanding on a
fully diluted basis (the "Minimum Condition") and to the other conditions set
forth in Annex A hereto, shall use all reasonable efforts to consummate the
Offer in accordance with its terms as soon as legally permitted to do so under
applicable law. The obligations of Purchaser to accept for payment and to pay
for any Shares validly tendered and not withdrawn on or prior to the expiration
of the Offer shall be subject only to the Minimum Condition and the other
conditions set forth in Annex A. The Offer shall be made by means of an Offer to
Purchase (the "Offer to Purchase") containing the terms set forth in this
Agreement and shall be subject to the Minimum Condition and the other conditions
set forth in Annex A. Purchaser shall not (i) amend or waive the Minimum
Condition (ii) decrease the Offer Price or change the form of consideration
payable in the Offer (iii) decrease the number of Shares sought or (iv) amend
any other condition of the Offer in any manner adverse to the holders of the
Shares, in each case, without the written consent of the Company; provided, that
if on the initial scheduled expiration date of the Offer, which shall be twenty
(20) business days after the date the Offer is commenced, all conditions to the
Offer shall not have been satisfied or waived, Purchaser may, from time to time,
in its sole discretion, extend the expiration date. Purchaser shall, on the
terms and subject to the prior satisfaction or waiver of the conditions of the
Offer and as promptly as practicable after the expiration of the Offer, accept
for payment and pay for Shares tendered, provided, that if, immediately prior to
the initial expiration date of the Offer (as it may be extended), the number of
the Shares tendered and not withdrawn pursuant to the Offer equals less than 90%
of the outstanding Shares, Purchaser may extend the Offer for a period not to
exceed ten (10) business days, notwithstanding that all conditions to the Offer
are satisfied as of such expiration date of the Offer.

              (b)       As soon as practicable on the date the Offer is
commenced, Parent and Purchaser shall file with the United States Securities and
Exchange Commission (the "SEC") a Tender Offer Statement on Schedule 14D-1 with
respect to the Offer (together with all


                                        2

<PAGE>   9
amendments and supplements thereto and including the exhibits thereto, the
"Schedule 14D-1"). The Schedule 14D-1 will include, as exhibits, the Offer to
Purchase and a form of letter of transmittal and summary advertisement (which
documents, together with any amendments and supplements thereto, and any other
SEC schedule or form which is filed in connection with the Offer and related
transactions, are referred to collectively herein as the "Offer Documents"). The
Offer Documents will comply in all material respects with the provisions of
applicable federal securities laws and Delaware Law and, on the date filed with
the SEC and on the date first published, mailed or given to the Company's
stockholders, will not contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary in order
to make the statements therein, in light of the circumstances under which they
were made, not misleading, except that no representation is made by Parent or
Purchaser with respect to information furnished by the Company to Parent or
Purchaser, in writing, expressly for inclusion in the Offer Documents. The
information supplied by the Company to Parent or Purchaser, in writing,
expressly for inclusion in the Offer Documents and by Parent or Purchaser to the
Company, in writing, expressly for inclusion in the Schedule 14D-9 will not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading.

              (c)       Parent and Purchaser will take all steps necessary to
cause the Offer Documents to be filed with the SEC and to be disseminated to
holders of the Shares, in each case as and to the extent required by applicable
federal securities laws. Each of Parent and Purchaser and the Company agrees to
promptly (i) correct any information provided by it for use in the Schedule
14D-1 or the Offer Documents if and to the extent that such information shall
have become false or misleading in any material respect and (ii) supplement the
information provided by it specifically for use in the Schedule 14D-1 or the
Offer Documents to include any information that shall become necessary in order
to make the statements therein, in light of the circumstances under which they
were made, not misleading. Parent and Purchaser further agree to take all steps
necessary to cause the Schedule 14D-1 as so corrected to be filed with the SEC
and to be disseminated to holders of the Shares, in each case as and to the
extent required by applicable federal securities laws. The Company and its
counsel shall be given the reasonable opportunity to review the Schedule 14D-1
before it is filed with the SEC. In addition, Parent and Purchaser will provide
the Company and its counsel, in writing, with any comments, whether written or
oral, Parent, Purchaser or their counsel may receive from time to time from the
SEC or its staff with respect to the Offer Documents promptly after the receipt
of such comments.

         Section 1.2    Company Actions.

              (a)       The Company hereby approves of and consents to the Offer
and represents and warrants that (x) the Board of Directors, at a meeting duly
called and held on July 27, 1999, at which a majority of the directors was
present: (i) duly approved and adopted this Agreement and the transactions
contemplated hereby, including the Offer and the Merger (collectively, the
"Transactions"); (ii) resolved to recommend that the stockholders of the

                                        3

<PAGE>   10



Company accept the Offer, tender their Shares pursuant to the Offer and approve
and adopt this Agreement and the Transactions; and (iii) determined that this
Agreement and the Transactions are fair to, and in the best interests of, the
stockholders of the Company and (y) Wasserstein Perella & Co., Inc. has rendered
to the Board of Directors its opinion that the consideration to be received by
the Company's stockholders pursuant to the Offer and the Merger is fair to such
holders from a financial point of view.

              (b) As soon as practicable on the date the Offer is commenced, the
Company shall file with the SEC a Solicitation/Recommendation Statement on
Schedule 14D-9 (together with any and all amendments or supplements thereto and
including the exhibits thereto, the "Schedule 14D-9"). The Schedule 14D-9 will
comply in all material respects with the provisions of applicable federal
securities laws and, on the date filed with the SEC and on the date first
published, mailed or given to the Company's stockholders, will not contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading, except
that no representation is made by the Company with respect to information
furnished by Parent or Purchaser, in writing, expressly for inclusion in the
Schedule 14D-9. The Company further agrees to take all steps necessary to cause
the Schedule 14D-9 to be filed with the SEC and to be disseminated to holders of
the Shares, in each case as and to the extent required by applicable federal
securities laws. The Company shall mail, or cause to be mailed, such Schedule
14D-9 to the stockholders of the Company at the same time the Offer Documents
are first mailed to the stockholders of the Company together with such Offer
Documents. The Schedule 14D-9 and the Offer Documents will contain the
recommendations of the Board of Directors described in Section 1.2(a), subject
to the terms of this Agreement. The Company will promptly correct the Schedule
14D-9 if and to the extent that it shall have become false or misleading in any
material respect (and each of Parent and Purchaser, with respect to written
information supplied by it specifically for use in the Schedule 14D-9, shall
promptly notify the Company of any required corrections of such information and
cooperate with the Company with respect to correcting such information) and to
supplement the information contained in the Schedule 14D-9 to include any
information that shall become necessary in order to make the statements therein,
in light of the circumstances under which they were made, not misleading. The
Company further agrees to take all steps necessary to cause the Schedule 14D-9
as so corrected to be filed with the SEC and to be disseminated to holders of
the Shares, in each case as and to the extent required by applicable federal
securities laws. Purchaser and its counsel shall be given the opportunity to
review the Schedule 14D-9 before it is filed with the SEC. In addition, the
Company agrees to provide Purchaser and its counsel, in writing, with any
comments, whether written or oral, that the Company or its counsel may receive
from time to time from the SEC or its staff with respect to the Schedule 14D-9
promptly after the receipt of such comments or other communications.

              (c) In connection with the Offer, the Company will promptly
furnish or cause to be furnished or transmitted to Purchaser mailing labels and
any available listing or computer file, as Purchaser or its representative
requests, containing the names and addresses of

                                        4

<PAGE>   11



all record holders of Shares and security position listings of Shares held in
stock depositories, each as of a recent date, and shall promptly furnish
Purchaser with such additional information (including updated lists of
stockholders (updated as frequently as possible) and their addresses, mailing
labels and security position listing, each in such electronic format as may be
reasonably requested by Purchaser or its representative) and such other
information and assistance as Purchaser or its agents may reasonably request in
communicating the Offer to the record and beneficial holders of the Shares.

         Section 1.3    Directors.

              (a)       Subject to compliance with applicable law, promptly upon
the purchase of any Shares by Purchaser pursuant to the Offer, and from time to
time thereafter as Shares are acquired by Purchaser, Parent shall be entitled to
designate such number of directors, rounded up to the next whole number, on the
Board of Directors as is equal to the product of the total number of directors
on the Board of Directors (giving effect to the directors designated by Parent
pursuant to this sentence) multiplied by the percentage that the number of
Shares beneficially owned by Purchaser or any affiliate of Purchaser bears to
the total number of Shares then outstanding. In furtherance thereof, the Board
of Directors has resolved as part of its approval of this Agreement to promptly
increase the size of the Board of Directors to a number not in excess of ten
upon the request of Parent or secure the resignations of such number of
directors as is necessary to enable Parent's designees to be elected to the
Board of Directors in accordance with the terms of this Section 1.3, and upon
the request of Parent, the Company shall promptly increase the size of the Board
of Directors, or secure the resignations of such number of directors, as is
necessary to enable Parent's designees to be elected to the Board of Directors
in accordance with the terms of this Section 1.3, and shall take all actions
available to the Company to cause Parent's designees to be so elected (the date
Parent's designees are elected to the Board of Directors being referred to as
the "Appointment Date"). At such time, the Company shall, if requested by
Parent, take all actions available to it to cause persons designated by Parent
to constitute at least the same percentage (rounded up to the next whole number)
as is on the Board of Directors of (i) each committee of the Board of Directors,
(ii) each board of directors (or similar body) of each Subsidiary of the Company
and (iii) each committee (or similar body) of each such board.

              (b)       The Company shall promptly take all actions required
pursuant to Section 14(f) of the Exchange Act and Rule 14f-1 promulgated
thereunder in order to fulfill its obligations under Section 1.3(a), and shall
include in the Schedule 14D-9 mailed to stockholders with the Offer Documents
promptly after the commencement of the Offer (or an amendment thereof or an
information statement pursuant to Rule 14f-1 if Purchaser has not theretofore
designated directors) such information with respect to the Company and its
officers and directors as is required under Section 14(f) and Rule 14f-1 in
order to enable Parent's designees to be elected or appointed to the Board of
Directors immediately after the purchase of and payment for any Shares by
Purchaser. Parent or Purchaser shall supply the Company and be solely
responsible for any information with respect to either of them and their
nominees, officers, directors and


                                        5

<PAGE>   12



affiliates required by such Section 14(f) and Rule 14f-1. The provisions of this
Section 1.3(b) are in addition to and shall not limit any rights which
Purchaser, Parent or any of their respective affiliates may have as a holder or
beneficial owner of Shares as a matter of law with respect to the election of
directors or otherwise.

              (c)     If Parent's designees are elected or appointed to the
Board of Directors, subject to the other terms of this Agreement until the
Effective Time, the Board of Directors shall have at least one director who is a
director on the date hereof and who is neither an officer of the Company nor a
designee, stockholder, affiliate or associate (within the meaning of the federal
securities laws) of Parent (one or more of such directors, the "Independent
Directors"), provided that, if no Independent Directors remain, the other
directors shall designate one person to fill one of the vacancies who shall not
be either an officer of the Company or a designee, shareholder, affiliate or
associate of Parent and such person will be deemed to be an Independent Director
for purposes of this Agreement. Notwithstanding anything in this Agreement to
the contrary, if Parent's designees are elected to the Company's Board of
Directors, after the acceptance for payment of Shares pursuant to the Offer and
prior to the Effective Time, the affirmative vote of a majority of the
Independent Directors shall be required to (i) amend or terminate this Agreement
on behalf of the Company, (ii) exercise or waive any of the Company's rights,
benefits or remedies hereunder, if such exercise or waiver materially and
adversely affects holders of Shares other than Parent or Purchaser, (iii) extend
the time for performance of Purchaser's obligations hereunder or (iv) take any
other action by the Company under or in connection with this Agreement required
to be taken by the Board of Directors, if such action materially and adversely
affects holders of Shares other than Parent or Purchaser.

         Section 1.4  The Merger. Upon the terms and subject to the conditions
of this Agreement and Delaware Law, at the Effective Time, Purchaser will be
merged with and into the Company (the "Merger"), the separate corporate
existence of Purchaser will cease, and the Company will continue as the
surviving corporation. The Company as the surviving corporation after the Merger
hereinafter sometimes is referred to as the "Surviving Corporation."

         Section 1.5  Effective Time. The parties hereto shall cause a
Certificate of Merger to be executed and filed on the Closing Date (or on such
other date as Parent and the Company may agree) with the Secretary of State of
the State of Delaware (the "Secretary of State") in such form as required by,
and executed in accordance with, the relevant provisions of the Delaware Law.
The Merger will become effective on the date on which the Certificate of Merger
is duly filed with the Secretary of State or such time as is agreed upon by the
parties and specified in the Certificate of Merger, and such time is hereinafter
referred to as the "Effective Time."

         Section 1.6  Closing. The closing of the Merger (the "Closing") shall
take place at 10:00 a.m. on a date to be specified by the parties, which shall
be no later than the second business day after satisfaction or waiver of all of
the conditions set forth in Article VII hereof (the "Closing Date"), at the
offices of Warner, Norcross & Judd LLP, 900 Old Kent Building, 111

         Section 1.7  Directors and Officers of the Surviving Corporation. The
directors of Purchaser immediately before the Effective Time will be the initial
directors of the Surviving Corporation, and the officers of the Company
immediately before the Effective Time will be the initial officers of the
Surviving Corporation, in each case until their successors are duty elected or
appointed and qualified or until their earlier death, resignation or removal in
accordance with the Certificate of Incorporation and the Bylaws of the Surviving
Corporation. If, at the Effective Time, a vacancy exists on the Board of
Directors or in any office of the Surviving Corporation, such vacancy may
thereafter be filled in the manner provided by law.

         Section 1.8  Effect of the Merger. At the Effective Time, the effect of
the Merger will be as provided in the applicable provisions of Delaware Law.
Without limiting the generality of the foregoing, and subject thereto, at the
Effective Time all the property, rights, privileges, powers and franchises of
the Company and Purchaser will vest in the Surviving Corporation, and all debts,
liabilities and duties of the Company and Purchaser will become the debts,
liabilities and duties of the Surviving Corporation.

         Section 1.9  Subsequent Actions. If, at any time after the Effective
Time, the Surviving Corporation shall consider or be advised that any deeds,
bills of sale, assignments, assurances or any other actions or things are
necessary or desirable to vest, perfect or confirm of record or otherwise in the
Surviving Corporation, its right, title or interest in, to or under any of the
rights, properties or assets of either of the Company or Purchaser acquired or
to be acquired by the Surviving Corporation as a result of, or in connection
with, the Merger or otherwise to carry out this Agreement, the officers and
directors of the Surviving Corporation shall be authorized to execute and
deliver, in the name and on behalf of either the Company or Purchaser, all such
deeds, bills of sale, assignments and assurances and to take and do, in the name
and on behalf of each of such corporations or otherwise, all such other actions
and things as may be necessary or desirable to vest, perfect or confirm any and
all right, title and interest in, to and under such rights, properties or assets
in the Surviving Corporation or otherwise to carry out this Agreement.

         Section 1.10 Certificate of Incorporation; Bylaws.

              (a)     At the Effective Time the Certificate of Incorporation of
the Company, as in effect immediately before the Effective Time, will be the
Certificate of Incorporation of the Surviving Corporation and will be amended to
read in its entirety as set forth in Exhibit A hereto until thereafter amended
as provided by law and such Certificate of Incorporation.

              (b)     At the Effective Time the Bylaws of Purchaser, as in
effect immediately before the Effective Time, will be the Bylaws of the
Surviving Corporation until

                                        7

<PAGE>   14



thereafter amended as provided by law, the Certificate of Incorporation of the
Surviving Corporation and such By-Laws.

         Section 1.11  Stockholders' Meeting.

              (a)      If required by applicable law in order to consummate the
Merger, the Company, acting through its Board of Directors, shall, in accordance
with applicable law:

                       (i)   duly call, give notice of, convene and hold a
special meeting of its stockholders (the "Special Meeting") as promptly as
practicable following the acceptance for payment and purchase of Shares by
Purchaser pursuant to the Offer for the purpose of considering and taking action
upon the approval of the Merger and the adoption of this Agreement;

                       (ii)  prepare and file with the SEC a preliminary proxy
or information statement relating to the Merger and this Agreement and use its
reasonable best efforts, subject to the terms of this Agreement, (x) to obtain
and furnish the information required to be included by the SEC in the Proxy
Statement and, after consultation with Parent, to respond promptly to any
comments made by the SEC with respect to the preliminary proxy or information
statement and cause a definitive proxy or information statement, including any
amendment or supplement thereto (the "Proxy Statement") to be mailed to its
stockholders, provided that no amendment or supplement to the Proxy Statement
will be made by the Company without consultation with Parent and its counsel and
(y) to obtain the necessary approvals of the Merger and this Agreement by its
stockholders, and

                       (iii) subject to the terms of this Agreement, include in
the Proxy Statement the recommendation of the Board of Directors that
stockholders of the Company vote in favor of the approval of the Merger and the
adoption of this Agreement.

              (b)      Parent shall vote, or cause to be voted, all of the
Shares then owned by it, Purchaser or any of its other Subsidiaries and
affiliates in favor of the approval of the Merger and the approval and adoption
of this Agreement.

         Section 1.12  Merger Without Meeting of Stockholders. Notwithstanding
Section 1.11 hereof, if Parent, Purchaser and any other Subsidiaries of Parent
shall acquire in the aggregate at least 90% of the outstanding Shares, pursuant
to the Offer or otherwise, the parties hereto shall, at the request of Parent
and subject to Article VII, take all necessary and appropriate action to cause
the Merger to become effective as soon as practicable after such acquisition,

                                   ARTICLE II

                            CONVERSION OF SECURITIES

         Section 2.1 Conversion of Securities. At the Effective Time, by virtue
of the Merger and without any action on the part of Parent, Purchaser, the
Company or the holder of any of the following securities:

              (a)    Each Share issued and outstanding immediately before the
Effective Time (other than any Shares to be cancelled pursuant to Section 2.1(b)
and any Dissenting Shares) will be cancelled and extinguished and be converted
into the right to receive the Offer Price payable to the holder thereof, without
interest (the "Merger Consideration"), upon surrender of the certificate
formerly representing such Share in the manner provided in Section 2.3. All such
Shares, when so converted, will no longer be outstanding and will be canceled
automatically, retired and cease to exist. Each holder of a certificate
representing any such Shares will cease to have any rights with respect thereto,
except the right to receive the Merger Consideration therefor upon the surrender
of such certificate in accordance with Section 2.3, without interest.

              (b)    Each Share held in the treasury of the Company and each
Share owned by Parent or any direct or indirect wholly owned subsidiary of
Parent immediately before the Effective Time will be cancelled and extinguished,
and no payment or other consideration will be made with respect thereto.

              (c)    Each share of common stock, no par value, of Purchaser
issued and outstanding immediately before the Effective Time will thereafter
represent one validly issued, fully paid and nonassessable share of common
stock, no par value, of the Surviving Corporation.

         Section 2.2 Dissenting Shares.

              (a)    Notwithstanding any provision of this Agreement to the
contrary, any Shares held by a holder who has demanded and perfected his demand
for appraisal of his Shares in accordance with Delaware Law (including but not
limited to Section 262 thereof) and as of the Effective Time has neither
effectively withdrawn nor lost his right to such appraisal ("Dissenting
Shares"), will not be converted into or represent a right to receive cash
pursuant to Section 2.1, but the holder thereof will be entitled to only such
rights as are granted by Delaware Law.

              (b)    Notwithstanding the provisions of Section 2.2(a), if any
holder of Shares who demands appraisal of his Shares under Delaware Law
effectively withdraws or loses (through failure to perfect or otherwise) his
right to appraisal, then as of the Effective Time or the occurrence of such
event, whichever later occurs, such holder's Shares will automatically be
converted into and represent only the right to receive the Merger Consideration
as provided in

                                        9

<PAGE>   16



Section 2.1(a), without interest thereon, upon surrender of the certificate or
certificates representing such Shares pursuant to Section 2.3.

              (c)     The Company shall give Purchaser prompt notice of any
written demands for appraisal or payment of the fair value of any Shares,
withdrawals of such demands, and any other instruments served pursuant to
Delaware Law received by the Company. The Company shall not voluntarily make any
payment with respect to any demands for appraisal and shall not, except with the
prior written consent of Purchaser, settle or offer to settle any such demands.

         Section 2.3  Surrender of Shares; Stock Transfer Books.

              (a)     Before the Effective Time, Purchaser shall designate the
Company's transfer agent or another bank or trust company reasonably acceptable
to the Company to act as agent for the holders of Shares in connection with the
Merger (the "Exchange Agent") to receive the funds necessary to make the
payments contemplated by Section 2.1(a). At the Effective Time, Purchaser shall
deposit, or cause to be deposited, in trust with the Exchange Agent for the
benefit of holders of Shares the aggregate consideration to which such holders
shall be entitled at the Effective Time pursuant to Section 2.1(a).

              (b)     Each holder of a certificate or certificates representing
any Shares cancelled upon the Merger, which immediately prior to the Effective
Time represented outstanding Shares (the "Certificates"), and whose Shares were
converted pursuant to Section 2.1(a), may thereafter surrender such Certificate
or Certificates to the Exchange Agent, as agent for such holder, to effect the
surrender of such Certificate at Certificates on such holder's behalf for a
period ending 180 days after the Effective Time. Purchaser agrees that promptly
after the Effective Time it will cause the distribution to holders of record of
Shares as of the Effective Time of appropriate materials to facilitate such
surrender, including (i) a letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to the Certificates shall
pass, only upon delivery of the Certificates to the Exchange Agent and shall be
in a form and have such other provisions as Parent may reasonably specify) and
(ii) instructions for use in effecting the surrender of the Certificates in
exchange for the Merger Consideration. Upon the surrender of Certificates,
together with a letter of transmittal duly executed and such other documents as
may be reasonably required by the Exchange Agent, Purchaser shall cause the
Exchange Agent to pay the holder of such certificates in exchange therefor cash
in an amount equal to the Merger Consideration multiplied by the number of
Shares represented by such Certificate. Until so surrendered, each Certificate
(other than Certificates representing Dissenting Shares and Certificates
representing Shares held by Purchaser or in the treasury of the Company) will
represent solely the right to receive the aggregate Merger Consideration
relating thereto.

              (c)     If payment of the Merger Consideration in respect of
cancelled Shares is to be made to a Person other than the Person in whose name a
surrendered Certificate or instrument is registered, it will be a condition to
such payment that the Certificate or instrument

                                       10

<PAGE>   17



so surrendered will be properly endorsed with signatures guaranteed and
otherwise be in proper form for transfer and that the Person requesting such
payment shall have paid any transfer and other taxes required by reason of such
payment in a name other than that of the registered holder of the Certificate or
instrument surrendered or shall have established to the satisfaction of
Purchaser or the Exchange Agent that such tax either has been paid or is not
applicable.

              (d) At the Effective Time, the stock transfer books of the Company
will be closed and there will not be any further registration of transfers of
shares of any shares of capital stock thereafter on the records of the Company.
From and after the Effective Time, the holders of certificates evidencing
ownership of the Shares outstanding immediately prior to the Effective Time will
cease to have any rights with respect to such Shares, except as otherwise
provided for herein or by applicable law. If, after the Effective Time,
Certificates are presented to the Surviving Corporation, they will be cancelled
and exchanged for cash as provided in this Article II. No interest will accrue
or be paid on any cash payable upon the surrender of a Certificate or
Certificates which immediately before the Effective Time represented outstanding
Shares.

              (e) Promptly following the date which is 180 days after the
Effective Time, the Surviving Corporation will be entitled to require the
Exchange Agent to deliver to it any cash (including any interest received with
respect thereto), Certificates and other documents in its possession relating to
the Transactions, which had been made available to the Exchange Agent and which
have not been disbursed to holders of Certificates, and thereafter such holders
will be entitled to look to the Surviving Corporation (subject to abandoned
property, escheat or similar laws) only as general creditors thereof with
respect to the Merger Consideration payable upon due surrender of their
Certificates, without any interest thereon. Notwithstanding the foregoing
neither the Surviving Corporation nor the Exchange Agent will be liable to any
holder of a Certificate for Merger Consideration delivered to a public official
pursuant to any applicable abandoned property, escheat or similar law.

              (f) The Merger Consideration paid in the Merger will be net to the
holder of Shares in cash, subject to reduction only for any applicable federal,
state, local or foreign tax withholding or, as set forth in Section 2.3(c),
stock transfer taxes payable by such holder. To the extent that amounts are so
deducted and withheld by Parent or the Exchange Agent, (i) such amounts shall be
paid over to the applicable tax authority in a commercially reasonable manner
and time and (ii) such amounts shall be treated for purposes of this Agreement
as having been paid to the holder of the Shares in respect of which such
deduction and withholding was made.

              (g) In the event any Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit, reasonably satisfactory in form and
content to Parent, of that fact by the person claiming such Certificate to be
lost, stolen or destroyed and, if required by Parent, the posting by such person
of a bond in such reasonable amount as Parent may direct as indemnity against
any claim that may be made with respect to such Certificate, the Exchange


                                       11

<PAGE>   18



Agent or the Surviving Corporation shall issue in exchange for such lost, stolen
or destroyed Certificate the Merger Consideration to which such person is
entitled under this Article II.

         Section 2.4  Stock Plans.

              (a)     As soon as practicable following the date of this
Agreement, the Board of Directors (or, if appropriate, any committee
administering the Easco, Inc. Stock Option Plan dated December 17, 1993, as
amended effective November 24, 1996, and any other stock-based incentive plan or
arrangement of the Company (collectively, the "Stock Plans")) shall adopt such
resolutions or take such other actions as are required to provide for the
cancellation of all outstanding options to purchase Shares issued under the
Stock Plans (the "Options") upon the Effective Time (including but not limited
to the approval of such cancellation in accordance with the terms and conditions
set forth in that certain No-Action Letter, dated January 12, 1999, issued by
the SEC to Skadden, Arps, Slate, Meagher & Flom LLP for the purpose of ensuring
that such cancellation shall be exempt under Rule 16b-3 promulgated under the
Exchange Act), in exchange for a cash payment of an amount equal the product of
(x) the excess, if any, of the Offer Price over the per share exercise price
thereof and (y) the number of Shares subject to such Options for which such
Option shall not theretofore have been exercised, whether or not then vested and
exercisable.

              (b)     Each outstanding unvested restricted Share issued pursuant
to a Stock Plan (each, a "Restricted Share") shall, immediately prior to the
Effective Time, be canceled and be converted into, and become the right to
receive, the Offer Price which shall be payable in accordance with Section 2.1.

              (c)     All amounts payable pursuant to this Section 2.4 shall be
subject to any required withholding of taxes and shall be paid without interest.

              (d)     The Board of Directors (or, if appropriate, any committee
administering the Stock Plans) shall adopt such resolutions or take such actions
as are required to terminate the Stock Plans as of the Effective Time, to delete
as of the Effective Time the provision in any other benefit plan of the Company
providing for the issuance, transfer or grant of capital stock of the Company or
any interest in respect of capital stock of the Company and to ensure that
following the Effective Time, no holder of Options or any participant in any
Stock Plan or other Company benefit plan shall have any right thereunder to
acquire capital stock of the Company or the Surviving Corporation.

                                   ARTICLE III

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         Except as disclosed on the Company Disclosure Schedule (which shall
include a specific reference to the Section of this Agreement to which such
disclosure relates, with no disclosure to be deemed to apply to any other
Section of this Agreement to which it would not be readily apparent to a
reasonable person that such disclosure applies), the Company represents and
warrants to Parent and Purchaser as follows:

         Section 3.1 Organization. (a) Each of the Company and its Subsidiaries
is a corporation, partnership or other entity duly organized, validly existing
and in good standing under the laws of the jurisdiction of its incorporation or
organization and has all requisite corporate or other power and authority and
all necessary governmental approvals to own, lease and operate its properties
and to carry on its business as now being conducted, except where the failure to
be so organized, existing and in good standing or to have such power, authority,
and governmental approvals would not, individually or in the aggregate, have a
Company Material Adverse Effect. As used in this Agreement, "Subsidiary" means,
with respect to any party, any foreign or domestic corporation or other
organization, whether incorporated or unincorporated, of which (i) such party or
any other Subsidiary of such party is a general partner (excluding such
partnerships where such party or any Subsidiary of such party do not have a
majority of the voting interest in such partnership) or (ii) at least a majority
of the securities or other interests having by their terms ordinary voting power
to elect a majority of the Board of Directors or others performing similar
functions with respect to such corporation or other organization is directly or
indirectly owned or controlled by such party or by any one or more of its
Subsidiaries, or by such party and one or more of its Subsidiaries. As used in
this Agreement, "Company Material Adverse Effect" means any change in or effect
on the business of the Company or its Subsidiaries, taken as a whole, that could
reasonably be expected to be, individually or in the aggregate with any other
change or effect, materially adverse to (i) the business, operations, properties
(including intangible properties), condition (financial or otherwise), results
of operations, assets or liabilities of the Company or its subsidiaries, taken
as a whole, (other than any change or effect generally applicable to the
industry in which the Company and its Subsidiaries operate or changes in general
economic conditions) or (ii) the ability of the Company to consummate any of the
Transactions or to perform its obligations under this Agreement. The Disclosure
Schedule delivered to Parent prior to the execution of this Agreement (the
"Company Disclosure Schedule"), sets forth a complete list of the Company's
Subsidiaries.

         (b)         The Company and each of its Subsidiaries is duly qualified
or licensed to do business and in good standing in each jurisdiction in which
the property owned, leased or operated by it or the nature of the business
conducted by it makes such qualification or licensing necessary, except where
the failure to be so duly qualified or licensed and in good standing would not
individually or in the aggregate have a Company Material Adverse Effect. The
Company does not own any equity interest in any corporation or other entity.

                                       13

<PAGE>   20



         (c)         The Company has delivered to Parent complete and correct
copies of its Certificate of Incorporation and Bylaws and the Certificate of
Incorporation and Bylaws (or similar organizational documents) of each of its
Subsidiaries, in each case as amended to the date of this Agreement.

         Section 3.2 Capitalization. (a) The authorized capital stock of the
Company consists of 40,000,000 shares of Common Stock and 1,000,000 shares of
preferred stock, par value $.01 per share (the "Preferred Stock" ). As of the
close of business on July 27, 1999, (i) 9,673,224 Shares are issued and
outstanding, (ii) no shares of Preferred Stock are issued and outstanding, (iii)
1,027,798 Shares are issued and held in the treasury of the Company, and (iv) a
total of 836,475 Shares are issuable pursuant to outstanding Options. Section
3.2(a) of the Company Disclosure Schedule discloses (i) the number of shares
subject to each outstanding Option and the exercise price thereof and (ii) the
number of non-vested Restricted Shares. All the outstanding shares of the
Company's capital stock are, and all Shares which may be issued pursuant to the
exercise of outstanding Options will be, when issued in accordance with the
terms thereof, duly authorized, validly issued, fully paid and non-assessable
and free of preemptive rights with respect thereto. Except as set forth above,
there are no (i) shares of capital stock of the Company authorized, issued or
outstanding, (ii) existing options, warrants, calls, preemptive rights,
subscription or other rights, agreements, arrangements or commitments of any
character, relating to the issued or unissued capital stock of the Company or
any of its Subsidiaries, obligating the Company or any of its Subsidiaries to
issue, transfer or sell or cause to be issued, transferred or sold any shares of
capital stock or other equity interest in the Company or any of its Subsidiaries
or securities convertible into or exchangeable for such share or equity
interests, or obligating the Company or any of its Subsidiaries to grant extend
or enter into any such option, warrant, call, subscription or other right,
agreement, arrangement or commitment and (iii) outstanding contractual
obligations of the Company or any of its Subsidiaries to repurchase, redeem or
otherwise acquire or dispose of any Shares, or the capital stock of the Company
or of any Subsidiary or affiliate of the Company or to provide funds to make any
investment (in the form of a loan, capital contribution or otherwise) in any
Subsidiary or any other entity.

         (b)          All of the outstanding shares of capital stock of each of
the Subsidiaries are beneficially owned by the Company, directly or indirectly,
and all such shares have been validly issued and are fully paid and
nonassessable and are owned by either the Company or one of its Subsidiaries
free and clear of all liens, charges, security interests, options, claims,
mortgages, pledges, or other encumbrances and restrictions of any nature
whatsoever.

         (c)          There are no voting trusts or other agreements or
understandings to which the Company or any of its Subsidiaries is a party with
respect to the voting of the capital stock of the Company or any of the
Subsidiaries.

         (d)          There is no outstanding Indebtedness of the Company or any
of its Subsidiaries. No Indebtedness of the Company or its Subsidiaries contains
any restriction upon (i) the prepayment of such Indebtedness, (ii) the
incurrence of Indebtedness by the Company or its


                                       14

<PAGE>   21



Subsidiaries, respectively, or (iii) the ability of the Company or its
Subsidiaries to grant any liens on its properties or assets. Section 3.2 of the
Company Disclosure Schedule sets forth the amount of principal and unpaid
interest outstanding as of June 30, 1999 under each instrument evidencing
indebtedness of the Company and its Subsidiaries which will accelerate or become
due or result in a right of redemption or repurchase on the part of the holder
of such indebtedness (with or without due notice or lapse of time) as a result
of this Agreement, the Merger or the other Transactions. For purposes of this

         Section 3.3 Authorization; Validity of Agreement; Company Action. (a)
The Company has full corporate power and authority to execute and deliver this
Agreement and to consummate the Transactions. The execution, delivery and
performance by the Company of this Agreement, and the consummation by it of the
Transactions, have been duly and validly authorized by the Board of Directors by
unanimous vote, and no other corporate action on the part of the Company is
necessary to authorize the execution and delivery by the Company of this
Agreement and the consummation by it of the Transactions, except that
consummation of the Merger may require approval of the Company's stockholders as
contemplated by Section 1.11. This Agreement has been duly executed and
delivered by the Company and, assuming due and valid authorization, execution
and delivery hereof by Parent and Purchaser, is a valid and binding obligation
of the Company enforceable against the Company in accordance with its terms,
except that (i) such enforcement may be subject to applicable bankruptcy,
insolvency or other similar laws, now or hereafter in effect, affecting
creditors' rights generally, and (ii) the remedy of specific performance and
injunctive and other forms of equitable relief may be subject to equitable
defenses and to the discretion of the court before which any proceeding therefor
may be brought.

         (b)         Neither the provisions of Section 203 of Delaware Law nor,
to the knowledge of the Company, any other takeover laws of any state or
jurisdiction are applicable to this Agreement or the other Transactions,
including the Merger and the purchase of Shares in the Offer. The affirmative
vote of the holders of a majority of the outstanding shares of Common Stock is
the only vote of the holders of any class or series of the Company's capital
stock which may be necessary to approve this Agreement and the other
Transactions, including the Merger.

         Section 3.4 Consents and Approvals; No Violations. Except for filings,
permits, authorizations, consents and approvals as may be required under, and
other applicable requirements of, the Exchange Act, the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended (the "HSR Act"), and the filing
of the Certificate of Merger pursuant to Delaware Law, none of the execution,
delivery or performance of this Agreement by the Company, the consummation by
the Company of the Transactions or compliance by the Company with any of


                                       15

<PAGE>   22



the provisions hereof will (i) conflict with or result in any breach of any
provision of the Certificate of Incorporation, the Bylaws or similar
organizational documents of the Company or any of its Subsidiaries, (ii) require
any filing with, or permit, authorization, consent or approval of, any court,
arbitral tribunal, administrative agency or commission or other governmental or
other regulatory authority or agency (a "Governmental Entity"), (iii) result in
a violation or breach of, or constitute (with or without due notice or lapse of
time or both) a default (or give rise to any right of termination, amendment,
cancellation or acceleration) under, any of the terms, conditions or provisions
of any note, bond, mortgage, indenture, lease, license, contract, agreement or
other instrument or obligation to which the Company or any of its Subsidiaries
is a party or by which any of them or any of their properties or assets may be
bound (the "Company Agreements") or (iv) violate any order, writ, injunction,
decree, statute, rule or regulation applicable to the Company, any of its
Subsidiaries or any of their properties or assets, except in the case of clauses
(ii), (iii) or (iv) where failure to obtain such permits, authorizations,
consents or approvals or to make such filings, or where such violations,
breaches or defaults would not, individually or in the aggregate, have a Company
Material Adverse Effect.

         Section 3.5 SEC Reports and Financial Statements. The Company has
timely filed with the SEC, and has heretofore made available to Parent, and with
respect to filings not yet due, will timely file and promptly make available to
Parent, true and complete copies of all forms, reports, schedules, statements
and other documents required to be filed by it since January 1, 1996, under the
Exchange Act or the Securities Act of 1933, as amended (the "Securities Act")
(as such documents have been amended since the time of their filing,
collectively, the "Company SEC Documents"). As of their respective dates, or if

including any financial statements or schedules included therein (a) did not, or
will not, with respect to filings not yet due, contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading and (b) complied, or will comply,
with respect to filings not yet due, in all material respects with the
applicable requirements of the Exchange Act or the Securities Act, as the case
may be, and the applicable rules and regulations of the SEC thereunder. None of
the Company's Subsidiaries is required to file any forms, reports or other
documents with the SEC. Each of the consolidated financial statements included
in the Company SEC Documents (the "Financial Statements") (i) has been prepared,
or will be prepared, with respect to filings not yet due, from, and is in
accordance with, the books and records of the Company and its consolidated
Subsidiaries, (ii) complies, or will comply, with respect to filings not yet
due, in all material respects with applicable accounting requirements and with

accordance with United States generally accepted accounting principles ("GAAP")

statements, to normal year-end audit adjustments) and (iv) fairly presents, or
will fairly present, with respect to filings not yet due, the consolidated
financial position and the consolidated results of operations and cash flows
(and

                                       16

<PAGE>   23



changes in financial position, if any) of the Company and its consolidated
Subsidiaries as of the times and for the periods referred to therein.

         Section 3.6 Absence of Certain Changes. From January 1, 1999 through
the date of this Agreement, (i) the Company and its Subsidiaries have conducted
their respective businesses only in the ordinary and usual course, (ii) there
has not occurred any event, change or effect (including the incurrence of any
liabilities of any nature, whether or not accrued, contingent or otherwise)
having, individually or in the aggregate, a Company Material Adverse Effect, and
(iii) neither the Company nor any of its Subsidiaries has taken any of the
actions that if taken after the date of this Agreement would be prohibited by
Section 5.2 hereof.

         Section 3.7 No Undisclosed Liabilities. Except (a) as disclosed in the
balance sheet contained in the most recent Financial Statements included in the
Company SEC Documents filed prior to the date of this Agreement (the "Recent
Balance Sheet") and (b) for liabilities and obligations (i) incurred in the
ordinary course of business and consistent with past practice since the date of
the Recent Balance Sheet, (ii) pursuant to the terms of this Agreement, or (iii)
as disclosed in Section 3.7 of the Company Disclosure Schedule, neither the
Company nor any of its Subsidiaries has any liabilities or obligations of any
nature, whether or not accrued, contingent or otherwise, that would,
individually or in the aggregate have a Company Material Adverse Effect or would
be required to be reflected or reserved against on a consolidated balance sheet
of the Company and its Subsidiaries (including the notes thereto) prepared in
accordance with GAAP as applied in preparing the Recent Balance Sheet.

         Section 3.8 Information in Proxy Statement. The Proxy Statement, if any
(or any amendment thereof or supplement thereto), will, at the date it or any
amendment or supplement is filed with the SEC, mailed to Company stockholders
and at the time of the meeting of Company stockholders to be held in connection
with the Merger, not contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary in order to
make the statements therein, in light of the circumstances under which they are
made, not misleading, except that no representation is made by the Company with
respect to statements made therein based on information supplied in writing by
Parent or Purchaser for inclusion in the Proxy Statement. The Proxy Statement
will comply as to form in all material respects with the provisions of the
Exchange Act and the rules and regulations thereunder.

         Section 3.9 Opinion of Financial Advisor. The Board of Directors has
received the opinion of Wasserstein Perella & Co., Inc., dated July 27, 1999 to
the effect that, as of such date, the consideration to be received in the Offer
and the Merger by the Company's stockholders is fair from a financial point of
view, a copy of which opinion has been delivered to Parent and Purchaser.

         Section 3.10 Brokers or Finders. The Company represents, as to itself
and its Subsidiaries and affiliates, that, except for Wasserstein Perella & Co.,
Inc., no agent, broker, investment banker, financial advisor or other firm or
person is or will be entitled to any brokers'


                                       17

<PAGE>   24



or finder's fee or any other commission or similar fee from the Company or any
of its Subsidiaries in connection with any of the transactions contemplated by
this Agreement.

         Section 3.11 Litigation. As of the date hereof, there is no suit,
claim, action, proceeding or investigation pending or, to the knowledge of the
Company, threatened against the Company or any of its Subsidiaries or any of
their respective properties or assets before any Governmental Entity which,
individually or in the aggregate, would have a Company Material Adverse Effect,
nor, to the knowledge of the Company, are there any facts, circumstances or
developments that are reasonably likely to give rise to any such suit, claim,
action, proceeding or investigation. Neither the Company nor any of its
Subsidiaries is subject to any outstanding order, writ, injunction or decree
which, individually or in the aggregate, has had, or in the future would
reasonably be expected to have, a Company Material Adverse Effect.

         Section 3.12 Compliance with Applicable Law. The Company and its
Subsidiaries hold all permits, licenses, variances, exemptions, orders and
approvals of all Governmental Entities necessary for the lawful conduct of their
respective businesses, except such permits, licenses, variances, exceptions,
orders or approvals the failure of which to hold, individually or in the
aggregate, has not had, or would reasonably be expected not to have, a Company
Material Adverse Effect (the "Company Permits"). The Company and its
Subsidiaries are in compliance in all material respects with the terms of the
Company Permits. The businesses of the Company and its Subsidiaries have not
been and are not being conducted in violation of any law, ordinance or
regulation of any Governmental Entity except for violations or possible
violations which have not had, or would reasonably be expected not to have, a
Company Material Adverse Effect. As of the date hereof, no investigation or
review by any Governmental Entity with respect to the Company or any of its
Subsidiaries is pending or, to the knowledge of the Company, threatened nor, to
the knowledge of the Company, has any Governmental Entity indicated an intention
to conduct the same.

         Section 3.13 Taxes. Each of the Company and its Subsidiaries has filed,
or caused to be filed, all material federal, state, local and foreign income and
other tax returns required to be filed by it, has paid or withheld, or caused to
be paid or withheld, all taxes of any nature whatsoever, with any related
penalties, interest and liabilities (any of the foregoing being referred to
herein as a "Tax"), that are shown on such tax returns as due and payable, or
otherwise required to be paid, other than such Taxes as are being contested in
good faith and for which adequate reserves have been established or such Taxes,
the failure of which to be paid or withheld would not have a Company Material
Adverse Effect. There are no claims or assessments pending against the Company
or its Subsidiaries for any alleged deficiency in any Tax, and the Company does
not know of any threatened Tax claims or assessments against the Company or any
of its Subsidiaries which if upheld could, individually or on the aggregate,
have a Company Material Adverse Effect. There is no material deferred
intercompany gain within the meaning of the Treasury regulations promulgated
under section 1502 of the Internal Revenue Code of 1986, as amended. There are
no waivers or extensions of any applicable statue of limitations to assess any
Taxes. All returns filed with respect to Taxes are true and correct in all

                                       18

<PAGE>   25



material respects, except for such returns, the failure of which to be so true
and correct would not have a Company Material Adverse Effect. There are no
outstanding requests for any extension of time within which to file any return
or within which to pay any Taxes shown to be due on any return.

         Section 3.14 ERISA. The Company has delivered to Parent a correct and
complete list and copy of each Company Plan and each Company Multiemployer Plan.
Each Company Plan complies in all material respects with the applicable
provisions of the Employee Retirement Income Security Act of 1974, as amended
("ERISA"), the Code and all other applicable statutes and governmental rules and
regulations, and (i) no "reportable event" (within the meaning of Section 4043
of ERISA) has occurred with respect to any Company Plan, (ii) neither the
Company nor any of its ERISA Affiliates has withdrawn, completely or partially,
from any Company Multiemployer Plan or instituted, or is currently considering
taking, any action to do so, and (iii) no action has been taken, or is currently
being considered to terminate any Company Plan subject to Title IV of ERISA.
Except as provided in the Recent Balance Sheet, no Company Plan, or any trust
created thereunder, has incurred any "accumulated funding deficiency" (as
defined in Section 302 of ERISA), whether or not waived, which would,
individually or in the aggregate, have a Company Material Adverse Effect. There
are no actions, suits or claims pending or, to the knowledge of the company,
threatened (other than routine claims for benefits) with respect to any Company
Plan which would have a Company Material Adverse Effect. Neither the Company nor
any of its ERISA Affiliates has incurred or reasonably expects to incur any
liability under or pursuant to Title IV or ERISA which would, individually or in
the aggregate, have a Company Material Adverse Effect. No prohibited
transactions described in Section 406 of ERISA or Section 4975 of the Code have
occurred. All Company Plans that are intended to be qualified under Section
401(a) of the Code have been determined by the Internal Revenue Service to be so
qualified, and the Company is not aware of any reason why any such Company Plan
is not so qualified in operation. Neither the Company nor any of its ERISA
Affiliates has been notified by any Company Multiemployer Plan that such Company
Multiemployer Plan is currently in reorganization or insolvency under and within
the meaning of Section 4241 or 4245 of ERISA or that such Company Multiemployer
Plan intends to terminate or has been terminated under Section 4041A of ERISA.
As used herein, (i) "Company Plan" means a "pension plan" (as defined in Section
3(2) of ERISA (other than a Company Multiemployer Plan)) or a "welfare plan" (as
defined in Section 3(1) of ERISA) established or maintained by the Company or
any of its ERISA Affiliates or as to which the Company or any of its ERISA
Affiliates has contributed or otherwise may have any liability; (ii) "Company
Multiemployer Plan" means a "multiemployer plan" (as defined in Section
4001(a)(3) of ERISA) to which the Company or any of its ERISA Affiliates is or
has been obligated to contribute or otherwise may have any liability; and (iii)
"ERISA Affiliate" means (A) any corporation which at any time on or before the
Effective Time is or was a member of the same controlled group of corporations
(within the meaning of Section 414(b) of the Code) as the Company, (B) any
partnership, trade or business (whether or not incorporated) which at any time
on or before the Effective Time is or was under common control (within meaning
of Section 414(c) of the Code) with the Company and (C) any entity which at any
time on or before the Effective Time is or was


                                       19

<PAGE>   26
a member of the same affiliated service group (within the meaning of Section
414(m) of the Code) as either the Company, any corporation described in clause
(A) of this clause (iii) or any partnership, trade or business described in
clause (B) of this clause (iii). No Company Plan (i) provides health, life
insurance or other welfare benefits to former employees (or their dependents or
beneficiaries) after retirement or termination of employment except as required
by Section 601 et seq. of ERISA or any applicable state law, death benefits or
retirement benefits under any "pension plan" (as defined in section 3(2) of
ERISA), deferred compensation benefits accrued as liabilities on the books of
the Company, any of its Subsidiaries or any ERISA Affiliates or benefits, the
full direct cost of which is borne by the current or former employee (or
beneficiary thereof) and (ii) no Company Plan provides additional benefits or
contains other provisions that would become effective upon or as a result of the
consummation of any of the transactions contemplated herein.

         Section 3.15 Environmental Matters. Except as would not reasonably be
expected to have a Company Material Adverse Effect:

              (a) the Company and each of its Subsidiaries has obtained and is
in compliance with the terms and conditions of all permits, licenses and other
authorizations required under applicable federal, state and local laws and
regulations as currently in effect relating to pollution or the protection or
clean-up of the environment ("Environmental Laws");

              (b) no asbestos requiring abatement, equipment containing
polychlorinated biphenyls above regulated levels or leaking underground or

the Company or any of its Subsidiaries;

              (c) the Company and each of its Subsidiaries is in compliance with
all applicable Environmental laws; and

              (d) neither the Company nor any of its Subsidiaries has received

incident, action or plan that has resulted in or reasonably threatens to result
in any legal liability to the Company or any of its Subsidiaries under, or
otherwise reasonably forms the basis of any claim, action, suit, proceeding,
hearing or investigation under, any applicable Environmental Laws in any such
case that remains outstanding.

<PAGE>   27



understanding with a labor union or labor organization; (ii) neither the Company
nor any of its Subsidiaries is the subject of any proceeding asserting that it
has committed an unfair labor practice or seeking to compel it to bargain with
any labor union or organization as to wages or conditions of employment; (iii)
there is no strike, work stoppage or other labor dispute involving it or any of
its Subsidiaries pending or, to the Company's knowledge, threatened, except, in
the case of clauses (ii) and (iii), for matters that would not, individually or
in the aggregate, have a Company Material Adverse Effect.

         Section 3.17 Intellectual Property. Except as would not reasonably be
expected to have a Company Material Adverse Effect, all patents, patent
applications, registered and unregistered copyrights, trade names, registered
and unregistered trademarks and trademark applications, trade secrets and other
proprietary information of the Company or any of its Subsidiaries (collectively,
"Company Intellectual Property") are owned by or licensed to the Company or any
of its Subsidiaries, free and clear of all liens, charges, security interests,
options, claims, mortgages, pledges or other encumbrances and restrictions of
any nature whatsoever. All Company Intellectual Property consisting of patents,
patent applications, trademarks and trademark applications are identified on
Schedule 3.17 of the Company Disclosure Schedule and, except as set forth
therein, have been duly registered and filed in and issued by the United States
Patent and Trademark Office or the corresponding offices of other countries, and
have been properly maintained and renewed in accordance with all applicable laws
and regulations in the United States and each such country. Use of Company
Intellectual Property by the Company and its Subsidiaries does not, and use by
Parent or its Subsidiaries at and following the Effective Time (subject to the

will not, require the consent of any other Person and the same are freely
transferable (except as otherwise provided by law). Except as would not

Person has an interest in or right or license to use, or the right to license
any other Person to use, any Company Intellectual Property, (ii) there are no
claims or demands of any other Person pertaining thereto and no proceeding has
been instituted, is pending or, to the knowledge of the company, threatened
which challenges the Company's or its Subsidiaries' rights in respect thereof
which, if resolved adversely to the Company, would materially impair the use or
value of such Company Intellectual Property before or after the Effective Time
or would, individually or in the aggregate, have a Company Material Adverse
Effect and (iii) to the Company's knowledge, no Company Intellectual Property is
being infringed by another Person or is subject to any outstanding order,
decree, ruling, charge, injunction, judgment or stipulation.

         Section 3.18 Year 2000 Matters. All information systems, computer
systems and electronic systems of the Company and each of its Subsidiaries are

Effect. "Millennium Compliant" means the quality of a system to provide all of
the following functions: (i) handle date information before, during and after
January 1, 2000, including accepting date input, providing date output, and
performing calculations on dates or portions of dates; (ii) function accurately
and without interruption before, during and

predetermined manner; and (iv) store and provide output of date information in

Company), and there has been no material dispute or complaint, between the
Company or any Subsidiary (on the one part) and any Major Customer or Major
Supplier (on the other part), other than routine disputes or complaints handled
in the ordinary course of business. A "Major Customer" means one of the 20
largest customers of the Company and its Subsidiaries in terms of revenue earned
during each of the two most recently completed fiscal years and the portion of
the current fiscal year prior to the date of this Agreement and a "Major
Supplier" means one of the 20 largest suppliers of Company and its Subsidiaries
in terms of purchases during each of the two most recently completed fiscal
years and the portion of the current fiscal year prior to the date of this

         Section 3.20 Title to and Condition of Assets. The Company and each of
its Subsidiaries have good, sufficient, and marketable title to all of their
properties and assets, whether real, personal, or a combination thereof, free
and clear of all liens, charges, security interests, options, claims, mortgages,
pledges or other encumbrances and restrictions of any nature whatsoever, except
for such imperfections of title, easements, restrictions, and encumbrances, if
any, as are not material in character, amount, or extent, and do not materially
detract from the value, or materially interfere with the present use, of the
properties subject thereto or affected thereby, except liens for real estate
taxes not yet due and payable. All of the personal property owned or used by the
Company is in good condition and repair (normal wear and tear excepted). With
respect to each parcel of real property owned, legally and beneficially, by the
Company or the Company's Subsidiaries ("Company Real Property"):

              (a) No Encroachments. Except for those encroachments that have
been insured over by a policy of title insurance, no building or improvement to
the Company Real Property encroaches on any easement or property owned by
another Person. No building or property owned by another Person encroaches on
the Company Real Property or on any easement benefitting the Company Real
Property. No claim of encroachment has been asserted by any Person with respect
to any parcel of the Company Real Property.

              (b) Zoning. Neither the Company, any of the Company's
subsidiaries, nor the Company Real Property is in material violation of any
zoning regulation, building restriction, restrictive covenant, ordinance, or
other law, order, regulation, or requirement relating to the Company Real
Property.

              (c) Buildings. All buildings and improvements to the Company
Real Property are in good condition (normal wear and tear excepted), are

serviced by all utilities necessary for the effective operation of business as
presently conducted at that location.

              (d) No Condemnation. None of the Company Real Property is the

                  The Company has delivered or made available to Parent a copy
of each written Company Agreement and a written description of each oral Company
Agreement specified above. Neither the Company nor any Subsidiary is in default
in any respect under any Company Agreement, and there has not occurred any event
which, with the lapse of time or the giving of notice or both, would constitute
such a default, except, in both cases, for such defaults as individually or in
the aggregate would not have a Company Material Adverse Effect.

provided by Caradon plc to the Company, neither the Company nor any other Person
makes any other express or implied representation or warranty on behalf of the
Company or any of its affiliates, and for the avoidance of doubt, neither the
Company nor any of its affiliates makes any express or implied representation or
warranty with respect to information contained in the confidential memorandum

projections set forth therein, or any projections otherwise provided to Parent
or the Purchaser.

                  Section 3.23 Full Disclosure. No representation or warranty of
the Company set forth in this Agreement and no statement contained in any
certificate or writing (including the Company Disclosure Schedule) delivered to
Parent or Purchaser as contemplated by this Agreement or in connection with the
Transactions, contains or will contain any untrue statement

                                   ARTICLE IV

             REPRESENTATIONS AND WARRANTIES OF PARENT AND PURCHASER

                  Parent and Purchaser, jointly and severally, represent and
warrant to the Company as follows:

                  Section 4.1 Organization. Each of Parent and Purchaser is a
corporation duly organized, validly existing and in good standing under the laws
of the jurisdiction of its incorporation or organization.

                  Section 4.2 Authorization; Validity of Agreement; Necessary
Action. Each of Parent and Purchaser has full corporate power and authority to
execute and deliver this Agreement and to consummate the Merger and the other
Transactions. The execution, delivery and performance by Parent and Purchaser of
this Agreement and the consummation by them of the Transactions have been duly
and validly authorized by the respective boards of directors of Parent and
Purchaser and by Parent as the sole stockholder of Purchaser, and no other
corporate action on the part of Parent or Purchaser is necessary to authorize
the execution and delivery by Parent and Purchaser of this Agreement and the
consummation by them of the Transactions. This Agreement has been duly executed
and delivered by Parent and Purchaser and, assuming due and valid authorization,
execution and delivery hereof by the Company, is a valid and binding obligation
of each of Parent and Purchaser enforceable against each of them in accordance
with its terms, except that (i) such enforcement may be subject to applicable
bankruptcy, insolvency or other similar laws, now or hereafter in effect,
affecting creditors' rights generally, and (ii) the remedy of specific
performance and injunctive and other forms of equitable relief may be subject to
equitable defenses and to the discretion of the court before which any
proceeding therefor may be brought.

                  Section 4.3 Consents and Approvals; No Violations. Except for
filings, permits, authorizations, consents and approvals as may be required
under, and other applicable requirements of, the Exchange Act, the HSR Act, and
the filing of the Certificate of Merger pursuant to Delaware Law, none of the
execution, delivery or performance of this Agreement by Parent or Purchaser, the
consummation by Parent or Purchaser of the Transactions or compliance by Parent
or Purchaser with any of the provisions hereof will (i) conflict with or result
in any breach of any provision of the respective Certificates of Incorporation
or Bylaws of Parent or Purchaser, (ii) require any filing with, or permit,
authorization, consent or approval of, any Governmental Entity, (iii) result in
a violation or breach of, or constitute (with or without due notice or lapse of
time or both) a default (or give rise to any right of termination, cancellation
or acceleration) under, any of the terms, conditions or provisions of any note,
bond, mortgage, indenture, lease, license, contract, agreement or other
instrument or obligation to which Parent or


                                       25

<PAGE>   32



any of its Subsidiaries or Purchaser is a party or by which any of them or any
of their respective properties or assets may be bound, or (iv) violate any
order, writ, injunction, decree, statute, rule or regulation applicable to
Parent, any of their Subsidiaries or any of their properties or assets, except
in the case of clause (ii), (iii) or (iv) where failure to obtain such permits,
authorizations, consents or approvals or to make such filings, or where such
violations, breaches or defaults would not, individually or in the aggregate,
have a material adverse effect on the ability of Parent and Purchaser to
consummate the Transactions.

                  Section 4.4 Information in Proxy Statement. None of the
information supplied by Parent or Purchaser in writing specifically for
inclusion or incorporation by reference in the Proxy Statement (or any amendment
thereof or supplement thereto) will, at the date mailed to stockholders and at
the time of the meeting of stockholders to be held in connection with the
Merger, contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they are made, not
misleading.

                  Section 4.5 Financing.  Parent and Purchaser have, and at the
Closing will have, sufficient funds available to finance and consummate the
Transactions.

                  Section 4.6 Brokers or Finders. Each of Purchaser and Parent
represents, as to itself and its affiliates, that, except for KPMG Corporate
Finance, no agent, broker, investment banker, financial advisor or other firm or
person is or will be entitled to any brokers' or finder's fee or any other
commission or similar fee from either Purchaser or Parent in connection with any
of the transactions contemplated by this Agreement.

                  Section 4.7 No Other Representations and Warranties. Except
for the representations and warranties contained in this Article IV and the
letter agreement dated of even date herewith provided by Caradon plc to the
Company, neither Parent, Purchaser nor any other Person makes any other express
or implied representation or warranty on behalf of the Parent, Purchaser or any
of their affiliates.

                  Section 5.1 Acquisition Proposals; No Solicitation.

                   (a) The Company agrees that it will immediately cease and
cause to be terminated any existing activities, discussions or negotiations, if
any, with any parties conducted heretofore with respect to any Takeover Proposal
(as defined below). In addition, the Company will not, will cause its officers
and directors not to, and will use its reasonable best efforts to ensure that
its employees (other than its officers or directors), investment bankers,
attorneys, accountants and other agents and representatives do not, directly or
indirectly: (i) initiate, solicit


                                       26

<PAGE>   33
or encourage, or take any action to facilitate the making of, any offer or
proposal which constitutes or is reasonably likely to lead to any Takeover
Proposal, (ii) enter into any agreement with respect to any Takeover Proposal,
or (iii) engage in any negotiations or discussions with, or provide any
information or data to, any Person (other than Parent or any of its affiliates
or representatives) relating to any Takeover Proposal; provided that nothing
contained in this Section 5.1 or any other provision hereof shall prohibit the
Company or the Board of Directors from (1) taking and disclosing to the
Company's stockholders a position with respect to a tender or exchange offer by
a third party pursuant to Rules l4d-9 and 14e-2 promulgated under the Exchange
Act or (2) making such other disclosure to the Company's stockholders as the
Board of Directors determines in good faith after consulting with its counsel
and determining that the failure to make such disclosure would constitute a
breach of the Board of Directors' fiduciary duties under applicable law.

                  (b) Notwithstanding the foregoing, prior to the acceptance of
Shares pursuant to the Offer, the Company may, in response to an unsolicited
written proposal with respect to a Takeover Proposal from a financially capable
third party that contains no financing condition, furnish information to, and
negotiate, explore or otherwise engage in substantive discussions with, such
third party, in each case only if (i) the Board determines in good faith by a
majority vote, after consultation with its financial advisors and after receipt
of advice of the outside legal counsel of the Company, that failing to take such
action would constitute a breach of the fiduciary duties of the Board, and (ii)
the Company obtains a confidentiality and standstill agreement no less favorable
to the Company than the Confidentiality Agreement entered into with Parent. The
Company shall promptly advise Parent in writing of the receipt of any inquiries
or proposals relating to a Takeover Proposal, indicating the name of the Person
making such inquiry or proposal, the terms and conditions thereof and any
actions taken pursuant to this Section 5.1(b). A copy of any written inquiry or
proposal relating to a Takeover Proposal shall be promptly furnished to Parent.

                  (c) As used in this Agreement, "Takeover Proposal" shall mean
any tender or exchange offer involving the Company, any proposal for a merger,
consolidation or other business combination involving the Company, any proposal
or offer to acquire in any manner greater than a 20% equity interest in, or
greater than a 20% portion of the business or assets of, the Company, any
proposal or offer with respect to any recapitalization or restructuring with
respect to the Company or any proposal or offer with respect to any other
transaction similar to any of the foregoing with respect to the Company, other
than pursuant to the Transactions.

                  Section 5.2 Interim Operations of the Company. The Company
covenants and agrees that, except (i) as expressly contemplated by this
Agreement, in compliance with applicable laws, and (ii) as set forth in Section
5.2 of the Company Disclosure Schedule or (iii) as agreed in writing by Parent
after the date hereof, and prior to the Appointment Date:

damages, liabilities, costs, expenses (including reasonable attorneys' fees and
expenses), judgments, fines and amounts paid in settlement in connection with
any such claim, action, suit proceeding or investigation. In the event of any
such claim, action, suit proceeding or investigation (whether arising before or
after the Effective Time) with respect to which the Company or the Surviving
Corporation is required to provide indemnification hereunder, (i) the Company or
the Surviving Corporation may, at its election, assume the defense of such
matter; provided, that in the event that the Company or the Surviving
Corporation fails to assume such defense or, under applicable standards of
professional conduct, a conflict of interest on any significant issue exists
between the Company and the Surviving Corporation, on the one hand, and the
Indemnified Parties on the other hand, the Indemnified Parties may retain
counsel satisfactory to them (which counsel shall be reasonably satisfactory to
the Company or the Surviving Corporation), and the Company, or the Surviving
Corporation after the Effective Time, shall pay all reasonable fees and expenses
of such counsel for the Indemnified Parties promptly as statements therefor are
received and (ii) the Company or the Surviving Corporation, as the case may be,
will use its reasonable efforts to assist in the vigorous defense of any such
matter; provided, that neither the Company nor the Surviving Corporation, as the
case may be, shall be liable for any settlement effected without its prior


                                       33

<PAGE>   40



written consent (which consent shall not be unreasonably withheld); and provided
further that neither the Company nor the Surviving Corporation, as the case may
be, shall have any obligation hereunder to any Indemnified Party when and if a
court of competent jurisdiction shall ultimately determine, and such
determination shall have become final and non-appealable, that indemnification
of such Indemnified Party in the manner contemplated hereby is prohibited by
applicable law. The Indemnified Parties as a group may retain only one law firm
to represent them with respect to each such matter unless there is, under
applicable standards of professional conduct, a conflict of interest on any
significant issue between the positions of any two or more Indemnified Parties,
or any similar impediment to the joint representation of multiple Indemnified
Parties by a single law firm. After the Effective Time, Parent shall guarantee
the performance by the Surviving Corporation of its obligations under this
Section 6.8(a).

                           (b)      Until the Effective Time, the Company shall
keep in effect Article VII of its Certificate of Incorporation, and thereafter
for a period of six years the Surviving Corporation shall keep in effect in its
Certificate of Incorporation or Bylaws a provision which provides for
indemnification of the Indemnified Parties to the extent required under Section
6.8(a).

                           (c)      Parent or the Surviving Corporation shall
maintain the Company's existing officers' and directors' liability insurance
("D&O Insurance") for a period of not less than six years after the Effective
Time; provided that Parent may substitute therefor policies of substantially
equivalent coverage and amounts containing terms no less favorable to such
former directors or officers; provided, further if the existing D&O Insurance
expires, is terminated or cancelled during such period, Parent or the Surviving
Corporation will use all reasonable efforts to obtain substantially similar D&O
Insurance; provided, further, that in no event shall Parent be required to pay
aggregate premiums for insurance under this Section 6.8(c) in excess of 200% of
the average of the aggregate premiums paid by the Company in 1997, 1998 and 1999
(through the date hereof) on an annualized basis for such purpose (the "Average
Premium"), which true and correct amounts are set forth in Section 6.8(c) of the
Company Disclosure Schedule; and provided, further that if Parent or the
Surviving Corporation is unable to obtain the amount of insurance required by
this Section 6.8(c) for such aggregate premium, Parent or the Surviving
Corporation shall obtain as much insurance as can be obtained for an annual
premium not in excess of 200% of the Average Premium.

                  Section 6.9       Purchaser Compliance.  Parent shall cause
Purchaser to comply with all of its obligations under or related to this
Agreement.

                  Section 6.10      Reasonable Best Efforts.

                           (a)      Prior to the Closing, upon the terms and
subject to the conditions of this Agreement, Purchaser and the Company agree to
use their respective reasonable best efforts to take, or cause to be taken, all
actions, and to do, or cause to be done, all things necessary, proper or
advisable under any applicable laws to consummate and make effective the


                                       34

<PAGE>   41
transactions contemplated by this Agreement as promptly as practicable
including, but not limited to (i) the preparation and filing of all forms,
registrations and notices required to be filed to consummate the transactions
contemplated by this Agreement and the taking of such actions as are necessary
to obtain any requisite approvals, consents, orders, exemptions or waivers by
any third party or Governmental Entity and (ii) the satisfaction of the other
parties' conditions to Closing. In addition, no party hereto shall take any
action after the date hereof that would reasonably be expected to materially
delay the obtaining of, or result in not obtaining, any permission, approval or
consent from any Governmental Entity necessary to be obtained prior to Closing.
Notwithstanding anything in this Agreement to the contrary, the Company shall
not, without Parent's prior written consent, commit to any divestiture
transaction and neither Parent nor any of its Subsidiaries (including Purchaser)
shall be required to divest or hold separate or otherwise commit to take any
action that limits its freedom of action with respect to, or its ability to
retain, the Company or any of its Subsidiaries, or any of the businesses,
product lines or assets of Parent or any of its Subsidiaries or that could,
individually or in the aggregate, reasonably be expected to result in a Material
Adverse Effect on the Company or Parent. Nothing contained in this Agreement
shall require any party to cure any breach of this Agreement by any other party
or waive any condition to its Transactions.

                  (b) Prior to the Closing, each party shall promptly consult
with the other parties hereto with respect to, provide any necessary information
with respect to and provide the other (or its counsel) copies of, all filings
made by such party with any Governmental Entity or any other information
supplied by such party to a Governmental Entity in connection with this
Agreement and the transactions contemplated by this Agreement. Each party hereto
shall promptly inform the other of any communication from any Governmental
Entity regarding any of the transactions contemplated by this Agreement. If any
party hereto or affiliate thereof receives a request for additional information
or documentary material from any such Government Entity with respect to the
transactions contemplated by this Agreement, then such party will endeavor in
good faith to make, or cause to be made, as soon as reasonably practicable and
after consultation with the other party, an appropriate response in compliance
with such request. To the extent that transfers of any permits issued by any
Governmental Entity are required as a result of execution of this Agreement or
consummation of the transactions contemplated hereby, the Company shall use its
reasonable best efforts to effect such transfers.

                  Section 6.11 Employee Matters. (a) Parent and the Purchaser
hereby agree to honor, and agree to cause the Surviving Corporation to honor,
and to make required payments when due under all contracts and agreements of the
Company and its Subsidiaries in effect as of the date hereof with any employee,
officer, director or executive or former employee, officer, or executive of the
Company or any Subsidiary thereof, including any such compensation, employment
and employee or director agreements in existence as of the date hereof (or as
modified to the extent permitted by Section 5.2 or by agreement of the parties
thereto).

                  (b) In addition to the foregoing, except as otherwise provided
in this Agreement, Parent hereby agrees that for a period of one year
immediately following the Effective


                                       35

<PAGE>   42



Time, it shall, or shall cause the Surviving Corporation to, maintain plans for
the benefit of the employees of the Company and its Subsidiaries which in the
aggregate provide benefits that are substantially comparable to those provided
to them under such Plans on the date hereof.

                  Section 6.12 Company Financial Statements and SEC Reports. As
soon as practicable, but in any event within 20 days after the end of each
fiscal month commencing with the execution of this Agreement, and continuing
through the Effective Time or termination of this Agreement, the Company shall
deliver to Parent unaudited balance sheets of the Company and its Subsidiaries
as at the end of such fiscal month and as at the end of the comparative fiscal
month of the preceding year, together with unaudited statements of income and
cash flows of the Company and its Subsidiaries for such fiscal month and for the
period from the beginning of the fiscal year to the end of such fiscal month and
the comparative fiscal month and period of the preceding year. Such balance
sheets and statements of income and cash flows shall be presented in
consolidated and consolidating form as of the end of each month which is also
the end of a fiscal quarter and shall be prepared in accordance with past
practice. The Company shall also promptly deliver to Parent a copy of each
Company SEC Document filed by the Company after the date of this Agreement
promptly following the filing of such SEC Document, provided, that the Company
shall not be required to deliver a copy of any Company SEC Document filed
through the SEC's EDGAR system if the Company provides Parent with prompt notice
of such filing.

                                   ARTICLE VII

           CONDITIONS TO EACH PARTY'S OBLIGATION TO EFFECT THE MERGER

                  The respective obligation of each party to effect the Merger
shall be subject to the satisfaction on or prior to the Closing Date of each of
the following conditions, any and all of which may be waived in whole or in part
by the Company, Parent or Purchaser, as the case may be, to the extent permitted
by applicable law:

                  Section 7.1     Stockholder Approval.  The Merger and this
Agreement shall have been approved and adopted by the requisite vote of the
holders of the Shares, if required by Delaware Law;

                  Section 7.2     Statutes; Court Orders. No statute, rule or
regulation shall have been enacted or promulgated, no final, nonappealable
judgment, writ, decree, order or injunction shall have been entered or enforced,
and no other legally binding, final and nonappealable action shall have been
taken by any domestic or foreign government, governmental, administrative or
regulatory authority or agency or by any court or tribunal of competent
jurisdiction, domestic or foreign, that in any of the foregoing cases has the
effect of making illegal, restraining, restricting or precluding consummation of
the Merger; and

                  Section 7.3     Purchase of Shares in Offer.  Purchaser
shall have made, or caused to be made, the Offer and shall have purchased, or
caused to be purchased, the Shares pursuant to


                                       36

<PAGE>   43



the Offer, provided that this condition shall be deemed to have been satisfied
with respect to the obligation of Parent and Purchaser to effect the Merger if
Purchaser fails to accept for payment or pay for Shares pursuant to the Offer in
violation of the terms of the Offer or of this Agreement.

                                  ARTICLE VIII

                                   TERMINATION

                  Section 8.1     Termination. This Agreement (other than this
Article VIII and Article IX) may be terminated and the transactions contemplated
herein may be abandoned at any time before the Effective Time, whether before or
after stockholder approval:

                           (a)    By mutual written consent of Parent and the
Board of Directors; or

                           (b)    By Parent if the Offer shall have expired or
been terminated without any Shares being purchased thereunder by Purchaser as a
result of the failure to meet the conditions set forth in Annex A; or

                           (c)    By either Parent or the Company if any
Governmental Entity shall have issued an order, decree or ruling or taken any
other action (which order, decree or ruling the parties hereto shall use their
reasonable best efforts to lift), in each case permanently restraining,
enjoining or otherwise prohibiting the transactions contemplated by this
Agreement; or

                           (d)    By Parent if, without any material breach by
Parent or Purchaser of its obligations under this Agreement, the purchase of
Shares pursuant to the Offer shall not have occurred on or before October 31,
1999; or

                           (e)    By the Company if, without any material breach
by the Company of its obligations under this Agreement, the purchase of Shares
pursuant to the Offer shall not have occurred on or before October 31, 1999; or

                           (f)    By the Company (i) if, prior to the purchase
of Shares pursuant to the Offer, there shall be a material breach of any of
Parent or Purchaser's representations, warranties or covenants hereunder, which
breach cannot be or has not been cured within ten days of the receipt of written
notice thereof or (ii) to allow the Company to enter into a definitive agreement
to consummate a Superior Proposal (as defined below); provided, that it has
complied with all provisions thereof; and provided further, that it furnishes a
copy of the Superior Proposal, containing all of the terms and conditions
thereof, to Parent at least two calendar days prior to terminating this
Agreement pursuant to this Section 8.1(f); or

                           (g)    By Parent if, prior to the purchase of Shares
pursuant to the Offer, the Company shall have breached in any material respect
(without reference to any materiality qualification contained therein) any
representation, warranty or covenant or other agreement


                                       37

<PAGE>   44
contained in this Agreement, which breach (i) would give rise to the failure of
a condition set forth in paragraph (f) or (g) of Annex A and (ii) cannot be or
has not been cured within ten days of the receipt of written notice thereof; or

                           (h)    By Parent if, (i) the Board of Directors shall
withdraw, modify, or change its recommendation or approval in respect of this
Agreement or the Offer in a manner adverse to Purchaser or (ii) the Board of
Directors shall have recommended any proposal other than by Parent or Purchaser
in respect of a Takeover Proposal; or

                           (i)    By Parent if (A) the Company has exercised a
right regarding a Takeover Proposal pursuant to Section 5.1(b) and, directly or
indirectly (including through its representatives), shall continue discussions
or negotiations with a third party for more than 20 business days after the date
of receipt of such Takeover Proposal or (B) a Takeover Proposal shall have been
publicly disclosed, commenced, proposed or communicated to the Company other
than by Parent or Purchaser, and the Board of Directors shall have not
affirmatively rejected such Takeover Proposal within 20 business days after the
earlier of receipt or the public disclosure of such Takeover Proposal.

A "Superior Proposal" is a bona fide written Takeover Proposal submitted by any
Person other than Parent or Purchaser on an unsolicited basis that the Board of
Directors determines in good faith, based on the advice of its financial
advisor, represents a transaction that is more financially favorable to the
stockholders of the Company than the Offer and the Merger.

                  Section 8.2     Effect of Termination.

                           (a)    In the event of termination of this
Agreement as provided in Section 8.1, written notice thereof shall forthwith be
given to the other party or parties specifying the provision hereof pursuant to
which such termination is made, and this Agreement shall forthwith become null
and void, and there shall be no liability on the part of Parent, Purchaser or
the Company, except (i) as set forth in Sections 6.5, 8.2 and 9.3 and (ii)
nothing herein shall relieve any party from liability for any material breach of
this Agreement.

                           (b)    If (i) the Company shall have terminated
this Agreement pursuant to Section 8.1(f)(ii), (ii) Parent shall have terminated
this Agreement pursuant to Section 8.1(h), or (iii) (A) Parent shall have
terminated this Agreement pursuant to Section 8.1(i), Section 8.1(g) (and the
breach giving rise to such right to terminate shall have been willful or in bad
faith) or Section 8.1(b) (because the Minimum Condition has not been satisfied)
and (B) in each case, the Company shall have consummated or entered into a
definitive agreement with respect to a Takeover Proposal within twelve months
following the date of such termination, then the Company shall pay to Parent,
(A) in the case of clause (i) or (ii) above, at the time of such termination,
and, in the case of clause (iii) above, upon the Company's consummation of or
entry into a definitive agreement regarding such Takeover Proposal, an amount
(the "Termination Fee") equal to $6,500,000 (which, in the case of a termination
pursuant to Section 8.1(g), shall


                                       38

<PAGE>   45



constitute liquidated damages with respect to any breach giving rise to a right
to terminate hereunder) plus an amount (not to exceed $1,500,000) equal to
Parent's and Purchaser's actual out-of-pocket expenses attributable to the
Offer, the Merger, this Agreement and the consummation of the transactions
contemplated hereby. Any amount due under this Section 8.2(b) shall be payable
by wire transfer to such account as Parent may designate in writing to the
Company.

                                   ARTICLE IX

                                  MISCELLANEOUS

                  Section 9.1 Amendment and Modification; Waiver. Subject to
applicable law, this Agreement may be amended, modified and supplemented in any
and all respects, whether before or after any vote of the stockholders of the
Company contemplated hereby, by written agreement of the parties hereto, by
action taken by their respective Boards of Directors or equivalent governing
bodies, at any time prior to the Effective Time with respect to any of the terms
contained herein; provided, that after the approval of this Agreement by the
shareholders of the Company, no such amendment, modification or supplement shall
reduce the amount or change the form of the Merger Consideration. At any time
prior to the Effective Time, by action taken or authorized by the respective
Boards of Directors of Parent or the Company, as applicable, Parent or the
Company may, to the extent legally allowed, (i) extend the time for the
performance of any of the obligations or other acts of the other (ii) waive any
inaccuracies in the representations and warranties contained herein or in any
document delivered pursuant hereto or (iii) waive compliance with any of the
agreements or conditions contained herein. Any agreement on the part of a party
to any such extension or waiver shall be valid only if set forth in a written
instrument signed on behalf of such party. The failure of any party to this
Agreement to assert any of its rights under this Agreement or otherwise shall
not constitute a waiver of those rights.

                  Section 9.2 Non-survival of Representations and Warranties.
None of the representations and warranties in this Agreement or in any schedule,
instrument or other document delivered pursuant to this Agreement shall survive
the Effective Time.

                  Section 9.3 Expenses. Except as expressly set forth in Section
8.2, all fees, costs and expenses incurred in connection with this Agreement and
the transactions contemplated hereby shall be paid by the party incurring such
fees, costs and expenses.

                  Section 9.4 Notices. All notices and other communications
hereunder shall be in writing and shall be deemed given if delivered personally,
telecopied (which is electronically confirmed) or sent by a nationally
recognized overnight courier service, such as FedEx, to the parties at the
following addresses (or at such other address for a party as shall be specified
by like notice):

and provisions hereof or the validity or enforceability of the offending term or
provision in any other situation or in any other jurisdiction. If the final

holding, voting or disposing of shares of Common Stock; and

                  WHEREAS, in consideration for the agreements contained herein,

became or may become an "interested stockholder" for purposes of Section 203 of
the DGCL, the board of directors of the Company has approved the agreement of

and validly executed and delivered by Stockholder and constitutes a valid and
binding agreement of Stockholder, enforceable against Stockholder in accordance

not, and the performance of Stockholder's obligations under this Agreement will
not, (i) conflict with or violate any law, statute, ordinance, rule, regulation,
order, judgment or decree applicable to Stockholder or by which it or any of its
properties is bound or affected, or (ii) result in any breach of or constitute a
default (or an event which with or without notice or lapse of time or both would
become a default) under, or give to others any rights of termination, amendment,
acceleration or cancellation of, or result in the creation of an encumbrance on
any of the Subject Securities, pursuant to, any note, bond, mortgage, indenture,
contract, agreement, lease, license, permit, franchise or other instrument or
obligation to which Stockholder is a party or by which Stockholder or any of its
Subject Securities are bound or affected, except for any such conflicts,

otherwise.

                  10. GOVERNING LAW. This Agreement shall be governed by and
construed in accordance with the laws of the State of Delaware regardless of the
laws that might otherwise govern under applicable principles of conflicts of

                  11. SPECIFIC PERFORMANCE. The parties hereto agree that if any
of the provisions of this Agreement are not performed in accordance with their

                  13. AMENDMENT; WAIVERS. This Agreement shall not be amended,
altered or modified except by an instrument in writing duly executed by each of
the parties hereto. No delay or failure on the part of any party hereto in
exercising any right, power or privilege under this Agreement shall impair any
such right, power or privilege or be construed as a waiver of any default or
any acquiescence thereto. No single or partial exercise of any such right, power
or privilege shall preclude the further exercise of such right, power or
privilege, or the exercise of any other right, power or privilege. No waiver
shall be valid against any party hereto, unless made in writing and signed by
the party against whom enforcement of such waiver is sought, and then only to
the extent expressly specified therein.

hereto hereby agrees to take or cause to be taken such further actions, to
execute, deliver and file or cause to be executed, delivered and filed such

                              STOCKHOLDER AGREEMENT

                  This STOCKHOLDER AGREEMENT (the "Agreement") is entered into
as of July 28, 1999 by and between Caradon Inc., a Delaware corporation
("Parent"), E Acqco Inc., a Delaware corporation and an indirect wholly owned
subsidiary of Parent ("Purchaser"), and                           , a
stockholder (the "Stockholder") of Easco, Inc., a Delaware corporation (the
"Company").

                  WHEREAS, pursuant to an Agreement and Plan of Merger, dated as
of July 28, 1999 (the "Merger Agreement"), by and among Parent, Purchaser and
Company, it is proposed that Purchaser will make a tender offer (the "Offer") to
acquire any and all shares of the issued and outstanding common stock, $.01 par
value (the "Common Stock"), of the Company and that, following the Offer,
Purchaser will be merged with and into the Company (the "Merger") and, as a
result of the Merger, the separate corporate existence of Purchaser shall cease
and the Company shall continue as the surviving corporation of the Merger (the
"Surviving Corporation"); and

                  WHEREAS, the Company, as the Surviving Corporation of the
Merger, will become an indirect wholly owned subsidiary of Parent; and

                  WHEREAS, in order to induce Parent and Purchaser to enter into
the Merger Agreement, which they otherwise would not do, Stockholder has agreed
to execute and deliver to Parent this Agreement; and

                  WHEREAS, prior to the date hereof, Parent and Stockholder had
no agreement, arrangement or understanding (as defined in Section 203 of the
Delaware General Corporation Law (the "DGCL")) for the purpose of acquiring,
holding, voting or disposing of shares of Common Stock; and

                  WHEREAS, in consideration for the agreements contained herein,
prior to the date hereof, and prior to the time at and date on which Parent


                                        1

<PAGE>   2
became or may become an "interested stockholder" for purposes of Section 203 of
the DGCL, the board of directors of the Company has approved the agreement of
Stockholder to vote as provided in Section 2 of this Agreement and not to
transfer shares of Common Stock as provided in Section 4 of this Agreement;

                  NOW, THEREFORE, in consideration of the foregoing and for
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties hereto agree as follows:

                  1. DEFINITIONS. Capitalized terms used and not defined herein
 shall have the meanings in the Merger Agreement.

                  2. TENDER. Stockholder hereby irrevocably agrees, for the
period from the date hereof through the Effective Time or the date on which the
Merger Agreement is terminated in accordance with its terms, whichever is
earlier (such period being hereinafter referred to as the "Term"), to tender all
of the Subject Securities (as defined below) into the Offer.

                  3. COVENANTS OF STOCKHOLDER. During the Term, and except as
specifically contemplated hereby, Stockholder shall not (i) directly or
indirectly sell, transfer, pledge, encumber, assign or otherwise dispose of, or
enter into any contract, option or other arrangement or understanding with
respect to the sale, transfer, pledge, encumbrance, assignment or other
disposition of, any of the Subject Securities, unless the transferee of the
Subject Securities, prior to and as a condition to any transfer of the Subject
Securities, executes and delivers an agreement in substantially the form hereof
or such transfer is otherwise approved in advance in writing by Parent and
Purchaser, (ii) grant any proxies, deposit any Subject Securities into a voting
trust or enter into an agreement with respect to any Subject Securities, (iii)
voluntarily take any action which would have the effect of preventing or
inhibiting Stockholder from performing his obligations under this Agreement or
(iv) indirectly, solicit (including by way of furnishing information) or respond
to any inquiries or the making of any proposal by any person or entity (other
than Parent or any affiliate of Parent) with respect to the Company that
constitutes or could reasonably be expected to lead to a Takeover Proposal. If
Stockholder receives any such inquiry or proposal, then he shall promptly inform
Parent of the terms and conditions, if any, of such inquiry or proposal and the
identity of the person making it. Stockholder will immediately cease and cause
to be terminated any existing activities, discussions or negotiations with any
parties conducted heretofore with respect to any of the foregoing.

                  4. STOCKHOLDER'S REPRESENTATIONS. Stockholder is the record
and beneficial owner of the number of shares of Common Stock (the "Existing
Securities" and together with any shares of Common Stock or other securities
hereafter acquired by Stockholder, the "Subject Securities") set forth on the
signature page to this Agreement. Stockholder does not own any securities of the
Company on the date hereof other than the Existing Securities.

                  Stockholder has full power and authority to enter into and


                                        2

<PAGE>   3
perform all his obligations under this Agreement. This Agreement has been duly
and validly executed and delivered by Stockholder and constitutes a valid and
binding agreement of Stockholder, enforceable against Stockholder in accordance
with its terms. Stockholder hereby represents and warrants to Parent and
Purchaser that the execution and delivery of this Agreement by Stockholder does
not, and the performance of Stockholder's obligations under this Agreement will
not, (i) conflict with or violate any law, statute, ordinance, rule, regulation,
order, judgment or decree applicable to Stockholder or by which he or any of his
properties is bound or affected, or (ii) result in any breach of or constitute a
default (or an event which with or without notice or lapse of time or both would
become a default) under, or give to others any rights of termination, amendment,
acceleration or cancellation of, or result in the creation of an encumbrance on
any of the Subject Securities, pursuant to, any note, bond, mortgage, indenture,
contract, agreement, lease, license, permit, franchise or other instrument or
obligation to which Stockholder is a party or by which Stockholder or any of his
Subject Securities are bound or affected, except for any such conflicts,
violations, breaches, defaults or other alterations or occurrences that would
not prevent the performance by such Stockholder of his obligations under this
Agreement.

                  5. UNDERSTANDING OF THIS AGREEMENT. Stockholder has carefully
read this Agreement and has discussed its requirements, to the extent such
Stockholder believes necessary, with his counsel (which may be counsel to the
Company). Stockholder understands that the parties to the Merger Agreement will
be proceeding in reliance upon this Agreement.

                  6. HEADINGS. The headings of the sections of this Agreement
are inserted for convenience of reference only and do not form a part or affect
the meaning hereof.

                  7. COUNTERPARTS. This Agreement may be executed in
counterparts, each of which when so executed and delivered shall be an original,
but all of such counterparts shall together constitute one and the same
instrument.

                  8. ENTIRE AGREEMENT; ASSIGNMENT. This Agreement (i)
constitutes the entire agreement and supersedes all prior agreements and
understandings, both written and oral, among the parties hereto with respect to
the subject matter hereof and (ii) shall not be assigned by operation of law or
otherwise.

                  9. GOVERNING LAW. This Agreement shall be governed by and
construed in accordance with the laws of the State of Delaware regardless of the
laws that might otherwise govern under applicable principles of conflicts of
law.

                  10. SPECIFIC PERFORMANCE. The parties hereto agree that if any
of the provisions of this Agreement are not performed in accordance with their
specific terms or are otherwise breached, irreparable damage would occur, no
adequate remedy at law would exist and damages would be difficult to determine,
and that the parties shall be entitled to specific performance of the terms
hereof, in addition to any other remedy at law or equity.

person or persons any rights, benefits or remedies of any nature whatsoever
under or by reason of this Agreement.

                  12. AMENDMENT; WAIVERS. This Agreement shall not be amended,
altered or modified except by an instrument in writing duly executed by each of
the parties hereto. No delay or failure on the part of any party hereto in
exercising any right, power or privilege under this Agreement shall impair any
such right, power or privilege or be construed as a waiver of any default or
any acquiescence thereto. No single or partial exercise of any such right, power
or privilege shall preclude the further exercise of such right, power or
privilege, or the exercise of any other right, power or privilege. No waiver
shall be valid against any party hereto, unless made in writing and signed by
the party against whom enforcement of such waiver is sought, and then only to
the extent expressly specified therein.

                            CONFIDENTIALITY AGREEMENT


                  THIS CONFIDENTIALITY AGREEMENT, dated as of June 10, 1999
(this "Agreement"), is made by and between Easco, Inc., a Delaware corporation
("Easco," which term shall, for purposes of this Agreement, include its
subsidiaries) and Caradon Inc. ("Buyer," which term shall, for purposes of this
Agreement, include Caradon plc and all of its subsidiaries).

                  WHEREAS, Easco is prepared to furnish Buyer with certain
information that is confidential, proprietary or otherwise not publicly
available to assist in an evaluation (the "Evaluation") in connection with a
possible business combination transaction involving Easco and Buyer (a
"Transaction").

                  NOW, THEREFORE, as a condition to, and in consideration of,
Easco furnishing to Buyer Information (as defined herein), Easco and Buyer agree
as follows:

                  1. Nondisclosure of Information. Subject to Section 2, Buyer
agrees that, in connection with information it receives from Easco, Buyer will
(a) keep the Information confidential, (b) not use the Information in any manner
detrimental to Easco and (c) not use the Information other than in connection
with the Evaluation. Notwithstanding the preceding sentence, Buyer may disclose
Information to those of its Representatives (as defined herein) as are assisting
Buyer with the Evaluation; provided, however, that Buyer will first (i) inform
each of its Representatives receiving Information of the confidential nature of
the Information and of the obligations imposed by this Agreement and (ii) direct
its Representatives to treat the Information confidentially and in accordance
with the obligations imposed by this Agreement and not to use the Information
other than in connection with the Evaluation. Buyer will be responsible for (A)
any failure by Buyer or any of its Representatives (including, without
limitation, Representatives who, subsequent to the first date of disclosure of
Information hereunder, cease to be its Representatives) to treat the Information
confidentially and in accordance with the obligations imposed by this Agreement
or (B) the use by Buyer or by any of its Representatives or former
Representatives of the Information other than in connection with the Evaluation.
Subject to Section 2, without the prior written consent of Easco, neither Buyer
nor its Representatives will disclose to any person (1) that Information has
been made available to Buyer or its Representatives, (2) that discussions
relating to a Transaction are taking place or have terminated, or (3) any of the
terms, conditions or other facts with respect to such discussions, the
Evaluation or any Transaction.

                  2. Notice Preceding Compelled Disclosure. If Buyer or any of
its Representatives is legally compelled, pursuant to a subpoena, civil
investigative demand, regulatory demand or similar process, to disclose any
Information provided by or on behalf of Easco or which relates to Easco, Buyer
will promptly notify Easco to permit Easco to seek a protective order or take
other appropriate action. Buyer will also cooperate in all reasonable efforts by
Easco to obtain a protective order or other reasonable assurance that
confidential treatment will be accorded the Information. If, in the absence of a



<PAGE>   2
protective order, Buyer or any of its Representatives is compelled to disclose
Information as a matter of law (including as a matter of federal or state
securities law) or pursuant to the rules and policies of any securities
exchange, Buyer may disclose only that part of the Information as is required by
law to be disclosed (in which case, prior to such disclosure, Buyer will advise
and consult with Easco and its counsel as to such disclosure and the nature and
wording of such disclosure), and, if Easco seeks a protective order or takes
other action to obtain confidential treatment for any Information so disclosed,
Buyer or its Representatives will not oppose such efforts of Easco.

                  3. Treatment of Information. As soon as possible upon the
written request of Easco or upon the termination by either Easco or Buyer of the
Evaluation or the discussions relating to a Transaction, Buyer and its
Representatives will destroy (or, at their option, return to Easco) all
Information which has been provided in tangible form by or on behalf of Easco,
together with all copies thereof, as well as all Information that incorporates
information provided by or on behalf of Easco. Such destruction (or return) will
be confirmed in writing to Easco. Any Information not so destroyed (or returned)
will remain subject to this Agreement. Buyer acknowledges that it is aware and
that its Representatives have been or will be advised by it that the United
States securities laws prohibit any person who has material, non-public
information from purchasing or selling securities based on such information or
from communicating such information to any other person.

                  4. Public Information. This Agreement will not apply to such
portions of the Information that (a) are or become generally available to the
public through no action by Buyer or by Buyer's Representatives or (b) are or
become available to Buyer or Buyer's Representatives from a source, other than
Easco or its Representatives, which source Buyer believes, based upon reasonable
inquiry, is not prohibited from disclosing such portions by a contractual, legal
or fiduciary obligation or (c) Buyer or its Representatives can prove was
obtained as a result of work which is independent of and not based on any of the
Information.

                  5. No Warranty of Accuracy. Buyer understands that Easco will
endeavor to include in the Information materials it believes to be relevant for
the Evaluation, but Buyer acknowledges that neither Easco nor any of its
Representatives makes any representation or warranty as to the accuracy or
completeness of any Information. Neither Easco nor any of its Representatives
will have any liability to Buyer or its Representatives resulting from the use
of the Information, except for use of the Information in breach of this
Agreement.

                  6. Certain Actions. (a) During the course of the Evaluation,
neither Buyer nor its Representatives will initiate contact with any director,
officer, employee or person known to hold securities of Easco (other than
persons specifically authorized by Easco) regarding any matter relating to a
Transaction. If the Evaluation or the discussions relating to a Transaction are
terminated for any reason, Buyer and its Representatives will cease, during the
Restricted Period (as defined below), all such contacts, whether or not
previously authorized.




                                       -2-

<PAGE>   3



                  (b) As of the date hereof, except as previously disclosed in
writing to Easco, Buyer is not the beneficial owner of any securities of Easco
entitled to be voted generally in the election of directors or any direct or
indirect options or other rights to acquire any such securities ("Voting
Securities"). During the period beginning on the date of this Agreement and
ending two years after the effectiveness of any Termination Notice (the
"Restricted Period"), except as specifically requested in writing by Easco,
neither Buyer nor any of its Representatives as a principal will propose,
induce, or enter into or agree to enter into, singly or with any other person or
directly or indirectly, (i) any form of business combination, acquisition or
other similar transaction relating to Easco, (ii) any form of restructuring,
recapitalization or similar transaction with respect to Easco, or (iii) any
demand, request or proposal, or any request for consent, to amend, waive or
terminate any provision of this Section 6. Furthermore, during the Restricted
Period, except as specifically requested in writing by Easco and except, as to a
Representative, as contemplated by the last sentence of this Section 6(b),
neither Buyer nor any of its Representatives as a principal will, singly or with
any other person or directly or indirectly, (1) acquire, or offer, propose or
agree to acquire, by tender offer, purchase or otherwise, any Voting Securities,
(2) make, or in any way participate in, any solicitation of proxies with respect
to any Voting Securities (including by the execution of action by written
consent), (3) become a participant in any election contest with respect to
Easco, (4) seek to influence any person with respect to the voting or
disposition of any Voting Securities, (5) demand a copy of Easco's list of
stockholders or its other books and records, (6) participate in or encourage the
formation of any partnership, syndicate or other group that owns or seeks or
offers to acquire beneficial ownership of any Voting Securities or that seeks to
affect control of Easco or for the purpose of circumventing any provision of
this Agreement, or (7) otherwise act (including by providing financing for
another person) to seek or to offer to control or influence, in any manner, the
management, Board of Directors or policies of Easco. The provisions of clause
(1) of the immediately preceding sentence are subject, as to a Representative of
Buyer that is a financial advisor engaged by Buyer and is also a securities
firm, to the fact that such financial advisor may from time to time acquire
Voting Securities, for its own account or the account of customers, and,
accordingly, may hold positions in Voting Securities.

                  (c) During the Restricted Period, neither Buyer nor its
Representatives will directly or indirectly solicit (other than by means of
general advertisement or solicitation) for employment any of the current
directors, officers or managers of Easco with whom initial contact was made, or
who were specifically identified by Easco, during the course of the Evaluation
(other than, in the case of a Representative, employment of any such person in
the regular course of the Representative's hiring practices and not arising by
reason of the Evaluation, and in the case of Buyer, employment of any such
person in the regular course of Buyer's hiring practices done by employees of
Buyer not aware of this Agreement).

                  (d) The provisions of this Section 6 will survive for two
years after the effectiveness of any Termination Notice notwithstanding that
some or all of the Information has become publicly disclosed or that any portion
of this Agreement has become inoperative as to any portion of the Information.

                  7. Certain Obligations Only on Definitive Agreement. Easco and
Buyer agree that unless and until a Definitive Agreement regarding a Transaction
has been executed and delivered by each of Easco and Buyer and each other party
thereto, neither Easco nor Buyer will be under any legal obligation of any kind
with respect to any Transaction by virtue of this Agreement or any other written
or oral expression with respect to any Transaction. Except as provided in
Section 6 of this Agreement, Easco and its Representatives will be free to
conduct the process for pursuing any possible business combination transaction
as they determine in their discretion (including, without limitation, changing
any procedures relating to a Transaction, or negotiating with and entering into
a Definitive Agreement with any other person, without in any such case prior
notice to Buyer). Either Easco or Buyer may terminate the Evaluation and any
discussions relating to a Transaction only upon furnishing notice to the other
(a "Termination Notice"), which Termination Notice shall become effective
immediately upon the date that it is actually received. Notwithstanding any
other provision of this Agreement, neither Easco nor Buyer will terminate the
Evaluation or any discussions relating to a Transaction except by delivering a
Termination Notice as provided in the immediately preceding sentence, and no
such Termination Notice will alter any provision of this Agreement (unless the
other party expressly agrees in writing). Except as provided in Section 6 of
this Agreement, neither Easco nor Buyer will have any claim against the other or
any of its Representatives arising out of or relating to any Transaction other
than those claims, if any, as parties to a Definitive Agreement and then only in
accordance with the terms of such Definitive Agreement.

                  8. General Provisions. This Agreement will be deemed to be
effective as of the earlier to occur of (a) the date Information was first
disclosed by or on behalf of Easco in connection with the Evaluation or (b) the
date first written above. No failure or delay in exercising any right hereunder
will operate as a waiver thereof, nor will any single or partial exercise
thereof preclude any other or further exercise thereof or the exercise of any
other right. This Agreement, any amendment to this Agreement, or any waiver of
rights or any notice or consent hereunder will be operative for purposes of this
Agreement only if it is in writing and is signed by a Chairman, President or
duly authorized Vice President or Director of the party in whose name it is
signed. This Agreement may be executed in multiple counterparts, each of which
will be deemed an original for all purposes and all of which will constitute a
single instrument. This Agreement will be binding upon and inure to the benefit
of the parties hereto and their respective affiliates, successors and assigns.
Buyer acknowledges that Easco may be irreparably injured by any violation of the
terms of this Agreement; accordingly, Easco will be entitled to seek specific
performance and injunctive relief as remedies for any violation, in addition to
all other remedies available at law or equity. Buyer consents to personal
jurisdiction in any action brought in any federal or state court within the
State of Delaware having subject matter jurisdiction in the matter for purposes
