    Automated Security (Holdings) PLC (the "Company" and, together with its
consolidated subsidiaries, "ASH" or the "Group") publishes its consolidated
financial statements in pounds sterling. In this Annual Report on Form 20-F
("Form 20-F"), references to "US dollars", "dollars" or "$" are to the currency
of the United States; references to "pounds sterling", "B.P.", "pence" or "p"
are to the currency of the United Kingdom; and references to "FFr" are to the
currency of France. Merely for the convenience of the reader, this Form 20-F
contains the translations of certain pound sterling amounts into US dollar
amounts at specified rates. These translations should not be construed as
representations that the pound sterling amounts actually represent such US
dollar amounts or could be converted into US dollars at the rates indicated.
Unless otherwise stated, the translations of pounds sterling into US dollars
have been made at B.P.1.00 = $1.53, the noon buying rate in New York City for
cable transfers in pounds sterling as certified for customs purposes by the
Federal Reserve Bank of New York (the "Noon Buying Rate") on November 30, 1995.
The Noon Buying Rate differs from the rates used in the preparation of the
Group's Consolidated Financial Statements. See page F-2 of Consolidated
Financial Statements. On April 30, 1996 the Noon Buying Rate was B.P.1.00 =
$1.505. Unless the context otherwise indicates, references herein to a
particular year are to the Company's fiscal year ending on November 30 of that
year.
 
ITEM 1. DESCRIPTION OF BUSINESS
GENERAL
 
    ASH is a leading international electronic security group, primarily engaged
in the rental, sales, installation and servicing of electronic security systems
and equipment to safeguard property from a wide range of hazards. The Group's
principal markets are the United Kingdom, where it is headquartered, and the
United States.

    ASH is structured in two operational units: the UK (including 
Eire) and the US. The Group's current strategy is to focus its three core 
businesses, Modern Security Systems and TSL in the UK and API and the Sonitrol 
network in the United States. The Group's growth will be dependent on achieving
prudent financing and balancing expansion within the Group's strategy of 
reducing the present high level of gearing. ASH sees opportunities for growth 
not only in the traditional intruder alarm market by providing technological 
upgrades, such as alarm monitoring or acoustic or visual alarm verification 
systems, but also providing other security and loss prevention equipment 
products, particularly in the fast growing CCTV market. During 1995 the Group
disposed of a number of peripheral businesses so as to reduce debt and enable
the Group to focus on its core businesses, ensure positive trading cash flows
and increase shareholders' funds. The Board continues to address the Group's
high level of gearing as a priority and will continue to do so until this
problem is resolved.

    In the UK and Eire, ASH provides intruder alarms, various central station
monitoring services and other detection systems to customers in the commercial,
industrial, residential and public sectors. In 1995, the UK and Eire continuing
operations accounted for approximately 73% (1994: 72%) of the Group's net sales
of continuing operations. Existing customers account for a significant
percentage of both recurring and new business in the UK.  On February 7, 1993, 
ASH acquired Telecom Security Limited ("TSL") for B.P.6 million ($9 million) 
plus a contingent deferred payment of up to B.P. 1.4million ($2 million).
 
    Since 1989, ASH has operated in the US under the name of API Security Inc.
("API"), a company based in California which provides intruder alarms, central
station monitoring, guarding and fire alarm services. In September 1992, ASH's
US operations were expanded through the purchase of Sonitrol Corporation 
("Sonitrol") and Sonitrol Management Corporation ("SMC") for $42 million in 
cash. Sonitrol is the franchisor of the Sonitrol audio alarm verification 
system throughout North America and the UK. In 1995, the US operations 
accounted for approximately 27% (1994: 28%) of the Group's net sales from 
continuing operations.
 
    The Company is the successor to Modern Automatic Alarms Limited, which was
established in 1964. By 1979, ASH had established itself as the market leader in
the intruder alarms business in the United Kingdom. Since that time, the Group
has broadened the extent and scope of its operations. In the years 1993 through
1995, ASH spent an aggregate of approximately B.P.10.6 million (excluding 
liabilities assumed of approximately B.P.6.2 million) on acquisitions and 
investments in related companies. On August 31, 1994 ASH acquired certain assets
of Sonitrol of Eugene in Oregon, U.S. for an initial consideration of $2.1 
million plus a deferred payment of $0.4 million.

RECENT DEVELOPMENTS
 
    On December 21, 1995, the Group reached agreement with its principal 
bankers to extend the majority of the Group's committed facilities of 
B.P. 83.4 million through January 2, 1998. This new facility consolidates the 
B.P. 66.3 million previously available under the Group's Multiple Option Loan 
facility and the majority of the B.P. 17.1 million previously available from 
bilateral facilities. Additionally, the Group had uncommitted overdraft and 
working capital lines at November 30, 1995 totaling in excess of B.P. 5.6 
million. The terms of the 8.28% Senior Notes were also amended by agreement 
with the Prudential Insurance Company of America on December 21, 1995. The 
maturity date of the Senior Notes has also been amended to January 2, 1998 and 
the terms of the Senior Notes and the bank facilities are treated on an 
equivalent basis. As part of the aforementioned agreement with the Group's
principal bankers and the Prudential Insurance Company of America, the Group's
indebtedness to its principal bankers and the holders of the Senior Notes is 
secured by pledges over the majority of the assets of the Group. 

    The Directors have not recommended payment of a dividend in respect of the 
Ordinary Shares for 1995 or 1994. All of the dividends on the 5% Preference 
Shares and 6% Preference Shares were paid for 1994, but in 1995 only the 
interim dividends have been paid on the due date. The balance of the unpaid 
dividends, B.P. 1,223,000 ($1,871,190) and B.P. 197,000 ($301,410) on the 6% 
Preference Shares and 5% Preference Shares, respectively have been accrued. 
The Company is unlikely to be in a position to pay dividends on its Ordinary 
or 5% and 6% Preference Shares to shareholders for the time being.

UK OPERATIONS (INCLUDING EIRE)
 
    In the UK, ASH provides intruder alarms, various central station monitoring
services and other detection systems. The UK operations consist principally of
the Group's businesses in intruder alarms (Modern Security Systems, formerly
Modern Alarms, Sonitrol and TSL). ASH has a leading share of the monitored alarm
market in the UK.
 
    Through Modern Security Systems, Sonitrol and TSL, ASH specializes in the
rental, installation and central station monitoring of intruder alarms,
primarily for commercial, industrial and residential customers in the United
Kingdom and Eire. Alarm systems installed on a customer's premises include
control and detection devices that respond to preset conditions such as
intrusion, various hazards, environmental conditions and industrial processes.
Alarm systems provide an audible warning at the premises. In addition, alarm
systems may be connected to one or more of ASH's central stations where alarm
and supervisory signals are received and recorded by means of either a digital
communicator using a standard telephone line, long range radio transmission or
private wire circuits that are rented from the telephone company. Depending upon
the type of service, central station personnel react by either relaying alarm
information to the local police or fire departments or to specialist response
agencies, or notifying the subscriber or taking other appropriate action.
 
    Modern Security Systems is one of the UK's market leaders in security 
systems catering primarily for the industrial and commercial market, although
approximately 25% of its systems are installed for residential customers. Some
two thirds of these systems are monitored by one of the central stations which
are located in Manchester and Glasgow. The majority of TSL's systems are also
monitored and are in the residential sector. Recurring revenues from these
installations in 1995 amounted to approximately B.P.53.5 million.
 
    In order to focus more effectively on the two main activities of customer
acquisition and customer retention, the Company devised plans which were
implemented on December 1, 1995 to reorganize Modern Security Systems into an
Upstream business concerned with sales and installation (customer acquisition)
and a Downstream business concerned with customer call receipt, customer
engineering service and alarm monitoring (customer retention). The basic Hub or
area office structure established in 1992 has been retained and the lower levels
of the organization have also largely been unchanged, so preserving the existing
links between local manager and team leader, and between team leaders and their
groups of service engineers, installation engineers or salesmen respectively.
The previous structure helped to bring on a new cadre of experienced management;
but it left spans of control too wide, giving insufficient emphasis both to
customer acquisition and customer retention. The benefits of the new structure
have already been realized in increasing focus on functional excellence, leading
to improved customer service.
 
    As part of the reorganization, the opportunity has been taken to establish a
separate salesforce within the Upstream business, focusing on CCTV and access
control sales and marketing itself as Modern Visual. After a healthy performance
in 1995, the new Modern Visual division expects to achieve improvements in
sales in the fast growing CCTV market.
 
    Within the Upstream business there continues to be a special team
serving our major national accounts. The marketing function supports the
Upstream business with lead generation reports, product development and market
surveys.
 
    ASH management believe that the existing installed base presents 
opportunities for growth within the present constraints of the Group's balance
sheet, especially in the form of technological upgrades from bell-only to 
monitored systems and from monitored systems to acoustic or visual verification.
 
                                       3
<PAGE>
    To provide its services in the UK, ASH has a field organization of
installers, supervisors and maintenance personnel and central station operators
in excess of 1,000 staff. ASH has 10 operational hubs across the United Kingdom.
 
US OPERATIONS
 
    ASH's US operations consist of two businesses: API Security and Sonitrol.
Together they represent one of the larger networks of electronic security
systems in the US market with approximately 220,000 systems (including franchise
operations).
 
    API Security was purchased by ASH in 1989 and is the leading intruder alarm,
central station monitoring and fire alarm services business in Southern
California. API is one of the largest providers of security systems in Southern
California with approximately 27,500 systems and an estimated 18% share of the
industrial/commercial market based on number of systems installed in Southern
California.
 
    Ninety eight percent of the total security systems installed and serviced by
API are for commercial customers. Over the past four years, API has extended its
activities into Northern California, principally San Francisco, as well as the
northern region of Mexico. At the same time API has consolidated its seven
central stations in California into one central monitoring superstation in Los
Angeles which has both conventional and Sonitrol monitoring capacity.
 
    API also provides alarm response, patrol and guard services, which perform
radio-despatch alarm investigations as well as regularly scheduled facility
inspections. These services form one of the largest commercial patrol services
in Southern California.
 
    API made a strategic decision to focus on three markets that have proved to
be profitable, demonstrated relatively low attrition rates and were markets in
which API had the ability to deliver a high level of customer service. These
markets are the upper end commercial, industrial and retail segments, including
warehousing and distribution centres servicing the western states. As part of
this strategy API exited the lower end retail market and sold its residential
portfolio in August 1994.
 
    Customer attrition in 1995 (cancellations) reached the lowest level in more
than 8 years. This is attributable to an overall organizational commitment to
exceeding customer expectations in all aspects of customer contact.
 
    The CCTV and access control aspect of API's business has expanded
significantly since 1990 when, following ASH's acquisition of API in 1989, the
decision was made to pursue the marketing of these products. CCTV and access
control sales now constitute almost half of the company's annual new sales
revenues. In addition API is a market leader in verification technology through
its Sonitrol, Teletrac, and remote CCTV monitoring applications.
 
    API initiated two major programmes in 1995. One is a computer system
conversion which is expected to be complete by August 1996. This covers the all
important central monitoring and service despatch systems as well as a
completely new accounting suite. The second major programme is the relocation of
the corporate offices, monitoring station and customer support centre to a new,
lower cost facility which will be complete before May 31, 1996. The combined
impact of these two projects is expected to result in annual cost savings of
over $2 million.
 
    In September 1992, ASH acquired Sonitrol Corporation and Sonitrol Management
Corporation (SMC) for $42 million in cash. Sonitrol Corporation is the 
franchisor of the Sonitrol audio alarm verification system throughout North 
America and the UK. Sonitrol Corporation has 170 franchises in North America and
Europe, covering approximately 100,000 proprietary and 90,000 conventional alarm
systems in the commercial, government, and residential sectors. ASH owns and 
operates a total of 26 Sonitrol franchises focused on southern California, 
Texas, Louisiana and the UK, and collects royalties generated from the other 
144 Sonitrol franchises that operate in the United States and Canada.
 
                                       4
<PAGE>
    Sonitrol offers an audio verified alarm monitoring detection system,
considered by industry experts and law enforcement agencies to be among the
highest quality systems available. In addition to its Signature audio intrusion
system, which is the only completely proprietary security system in the
industry, Sonitrol offers a complete line of CCTV, fire and access control
products.
 
    As franchisor, the primary operations of Sonitrol Corporation involve the
continual review and improvement of the Sonitrol product line and operating
system; development of a national marketing programme; maintenance of a national
accounts marketing team that refers major contracts to its franchisees, and
enforcement of the uniform Sonitrol operating standards.
 
    SMC, also acquired in 1992, owns 17 Sonitrol franchises in 8 states in the
central US. In August 1994 SMC also acquired the account base, but not the
underlying franchise rights for the Sonitrol franchise in Eugene, Oregon. SMC
services approximately 12,700 alarm and non-alarm accounts, largely for
commercial and institutional customers.
 
    In 1995 SMC consolidated its ten monitoring stations into a new superstation
in Dallas, Texas. This provides a solid platform for acquiring and supplying
contract monitoring services to its independent franchise network. The new
facility, which has the capacity to monitor in excess of 20,000 Sonitrol
customers, also allows SMC to provide a higher quality of service to its
existing customers.
 
TVX OPERATIONS
 
    ASH developed the TVX system, an innovative visual verification product that
transmits a black and white picture of an alarm triggering event to a receiving
central station, allowing verification of the event. TVX is essentially a
miniature camera mounted on a microchip which can be incorporated into any
security system and is activated by a device such as an infrared motion
detector. Images are converted into an electronic pulse and transmitted
instantaneously to a 24-hour monitoring centre where an operator can visually
verify that a burglary is in progress and notify the relevant authorities. TVX
International, a subsidiary of ASH, is responsible for the development,
marketing and sale of TVX.
 
    TVX Inc, a Colorado based joint venture between ASH (40%), Cellular, Inc
(40%) and local management (20%) was formed in 1993 to market the TVX technology
in the US. This joint venture will allow TVX International the opportunity to
market TVX's visual verification technology in conjunction with Cellular Inc's
transmission capabilities.
 
DISCONTINUED OPERATIONS
 
    In September 1995 ASH concluded the disposal of Modern Vitalcall Limited, a
wholly owned subsidiary, for B.P.1.5 million. In addition, the Group sold its
remaining Integrated Systems business in November 1995 for B.P.2.4 million, ASH
also disposed of its shareholdings in two related companies, Compagnie Generale
de Protection et Securite SA (France) for B.P.4.4 million and Microtech Security
(UK) Limited for B.P.1.0 million. These four disposals realized B.P.9.3 million
but resulted in a charge to the Profit and Loss account of approximately B.P.5.7
million, compensated for by a write back to reserves in respect of goodwill
written off of B.P.8.8 million.
 
    During 1995 these operations produced B.P.1.4 million of operating profit
compared to full year profit in 1994 of B.P.2.1 million which, combined with the
loss on discontinued operations from prior years of B.P.2.4 million, produced a
net loss in 1994 of B.P.0.3 million.
 
    Discontinued operations in 1994 and 1993 also include the operations of
Modern Integrated Systems Limited (MIS) which provided security and protection
for larger systems including fire detection, controlled entry, perimeter
protection and integrated systems.
 
    MIS had net sales in 1993 of B.P.7.2 million and a loss in 1994, including
warranty and contract realization provisions of B.P.2.4 million (1993: loss
B.P.5.1 million).
 
                                       5

INVESTMENTS
 
    The only remaining investment at November 30, 1995 relates to a loan of
B.P.654,000 (US$1,000,000) to TVX Inc, a related company in the USA.
 
SUPPLIERS
 
    Other than for Sonitrol operations ASH purchases its equipment from a number
of suppliers. Management believes that ASH is not dependent on any one supplier
for its equipment. Sonitrol operations source products from Advantor Corporation
pursuant to an agreement which is the subject of an arbitration (see Item 3. 
Legal Proceedings).
 
SALES AND MARKETING
 
    ASH provides services and equipment to customers in the commercial,
industrial, residential and public sectors. ASH's top ten customers did not
exceed 5% of net sales, and no single customer accounted for more than 2% of net
sales.
 
    A typical contract provides for a rental of the alarm system with an initial
installation fee and an agreement for monitoring and maintenance services.
Initial contracts are generally for a term of five years, with automatic renewal
on an annual or biannual basis thereafter unless terminated by either party. A
substantial number of these contracts are beyond their original term and are now
rented on an automatic renewal basis. Historically, a high percentage of
customers automatically renew their contracts at the end of the initial five
year contract.
 
    Sales of services and equipment are made by ASH's own sales force, primarily
based on recommendations and referrals made by existing customers and by third
parties, including insurance companies and law enforcement agencies. ASH also
relies on advertizing, trade shows and sponsorship to market its products. In
addition, ASH markets additional products and services to its existing
customers, which account for a significant percentage of recurring and new
business.
 
COMPETITION
 
    The electronic security systems industry is generally highly competitive and
fragmented. In the intruder alarms market, there are a large number of local
installers offering a limited range of services and smaller systems to customers
in the residential and general retail sectors. In the UK and US there are only a
few large regional or national companies that offer a range of security systems,
comparable to that offered by the Group.
 
RESEARCH AND DEVELOPMENT
 
    ASH believes that some limited expenditure on Group-sponsored research and
development ("R&D") is prudent in order to maintain its market position. The
principal R&D activities are undertaken in conjunction with third parties. The
Group's main involvement is to identify and specify its requirements to research
centers, original equipment manufacturers and suppliers.
 
    The Group's principal expenditure on R&D is in respect of the TVX miniature
camera, originally developed in conjunction with Edinburgh University. Further
development of this technology has been partly underwritten by the Commission of
the European Community, with ASH and its partners receiving a grant of 3.3
million ECU (B.P.2.3 million) to assist in installing cameras at various sites
in European countries.
 
    ASH's direct R&D expenditure was B.P.0.2 million, B.P.0.4 million and
B.P.1.3 million in 1995, 1994 and 1993 respectively.

TRADEMARKS
 
    The Group has several registered trademarks, none of which is of material
importance to the Group taken as a whole.
 
GOVERNMENT REGULATION
 
    In many of the countries in which they conduct business, Group companies
must obtain approval from appropriate government authorities to market their
systems, primarily because of the use of radio frequency technology. ASH
believes that all of its products are in compliance with currently applicable
governmental requirements. However, there can be no assurance that all products
of the Group subject to regulation will meet the requirements of such
regulations in all countries in which the Group markets its products, nor can
there be any assurance that adverse changes or amendments to existing
regulations will not occur.
 
EMPLOYEES
 
    During 1995, ASH had an average of approximately 3,006 (1994: 3,009)
employees worldwide. Approximately 2,327, 77%, of the Group's employees are
located in the United Kingdom and Eire and 679, 23%, in the United States.
 
    None of the Group's employees are subject to collective bargaining
agreements. ASH believes that its relations with its employees are generally
satisfactory.
 
ITEM 2. DESCRIPTION OF PROPERTY
- -------------------------------

    ASH has several central stations in the United Kingdom, Eire and the
United States. For a discussion of the role of central stations, see Item 1.
"Description of Business--UK Operations". In addition to central stations, the
Group has freehold and leasehold interests in properties in various countries,
none of which is significant to the Group as a whole. See Note 8 of Notes to
Consolidated Financial Statements.
 
ITEM 3. LEGAL PROCEEDINGS
- -------------------------
 
    Except as described below, there are no pending legal proceedings involving
the Group the outcome of which the management of ASH believes would have a 
material adverse effect on the financial condition or results of operations of 
the Group.
 
    Advantor Corporation ("Advantor") commenced a proceeding against Sonitrol 
Corporation ("Sonitrol") and ASH, Inc.  by filing a demand for commercial
arbitration with the American Arbitration Association. Advantor alleges that 
Sonitrol and ASH, Inc. (collectively, the "Companies") have breached the terms 
of a Trademark License and Franchise Support Agreement (the "License Agreement")
executed by Advantor and Sonitrol, which License Agreement appoints Advantor 
the exclusive supplier of certain products to the Sonitrol network. ASH, Inc.
is not a party to the License Agreement. Advantor seeks damages in excess of $1 
million and termination of the License Agreement. The Companies' position is 
that the claims are without merit. Moreover, based on discussions with personnel
from the Companies, counsel for the Companies believes that there are good 
grounds to  support the defenses which may be asserted by the Companies and that
these defenses, if sustained by the evidence at the arbitration hearing, should 
be sufficient to defeat recovery against the Companies.

    In the ordinary course of its business, ASH receives claims relating to
customer losses incurred as a result of the alleged failure of its security
systems owing to ASH's negligence or otherwise. In its customer contracts, ASH
seeks to limit its liability for such customer losses. These liability
limitation provisions have generally been held enforceable by courts in the
United Kingdom and the United States. Management believes that the Group
maintains insurance sufficient to protect the Group against the risks associated
with claims made in respect of customer contracts or otherwise.
 
ITEM 4. CONTROL OF REGISTRANT
- -----------------------------

    (a) As far as is known to the Company, it is not directly or indirectly
owned or controlled by another corporation or by any government.
 
    (b) (i) As of April 30, 1996, there was no person known by the Company to

    (c) The Company does not know of any arrangements the operation of which may

ITEM 5. NATURE OF TRADING MARKET
- --------------------------------
 
    The principal trading market for the Ordinary Shares is The International
Stock Exchange of the United Kingdom and the Republic of Eire Limited (the
"London Stock Exchange"). The London Stock Exchange utilizes a classification of
equity securities based on 12 levels of normal market size, ranging from 200,000
to 500 shares. These levels of normal market size reflect the turnover by value
in each company's shares over the past 12 months. The Company's Ordinary Shares
have been allocated an initial normal market size of 10,000 shares. The normal
market size classification for each equity security is subject to quarterly
review in the light of trading volumes in the previous quarter and to
adjustment, as appropriate. UK market makers are normally required to make a two
way market in sizes of not less than the normal market size and to report all
transactions to the London Stock Exchange within three minutes. In respect of
securities with a normal market size greater than 2,000, transactions of not
more than three times normal market size are published immediately as to size
and price, but transactions in excess of three times normal market size are not
published until after 90 minutes.
 
    The Company has a sponsored American Depositary Receipt ("ADR") facility
with The Bank of New York, as Depositary. The ADR holders hold American
Depositary Shares ("ADSs") representing Ordinary Shares which trade in the US on
the New York Stock Exchange (the "NYSE") under the symbol of ASI. Each ADS
represents two Ordinary Shares.

(1) The dollar prices reflect the actual prices per ADS.
 
    At April 30, 1996, there were a total of 2,167 record holders of the
Company's Ordinary Shares, including those represented by the ADSs, of which 665
had registered addresses in the United States and held a total of 41,496,246
Ordinary Shares. At April 30, 1996 there were 41,486,707 ADSs held of record by
651 ADR holders. Since certain of the Company's Ordinary Shares and ADSs are
held by nominees, the number of holders may not be representative of the number
of beneficial owners.
 
ITEM 6. EXCHANGE CONTROLS AND OTHER LIMITATIONS AFFECTING SECURITY HOLDERS
- --------------------------------------------------------------------------
 
    There are currently no United Kingdom exchange control restrictions on the
payment of dividends on the Ordinary Shares or the conduct of ASH's operations.
 
    There are no restrictions under the Company's Memorandum and Articles of
Association or under English law that limit the right of non-resident or non-UK
owners to hold or vote the Company's Ordinary Shares.
 
ITEM 7. TAXATION
- ----------------
 
    The following is a summary of the principal US Federal income and UK tax
consequences of the purchase, ownership and disposition of ADSs by an Eligible
US Holder (as defined below). The summary is (i) based upon tax laws and
practice of the United Kingdom and the United States as in effect on the date of
this Form 20-F, and (ii) based in part upon representations of the Depositary,
and assumes that each obligation in the Deposit Agreement among the Company, the
Depositary and holders of ADRs and any related agreement will be performed in
accordance with its terms. Future legislative, judicial or administrative
changes could modify the conclusions expressed below.
 
    For the purposes of the current United Kingdom-United States double tax
conventions and for the purposes of the United States Internal Revenue Code of
1986, as amended (the "Code"), Eligible US Holders of ADSs will be treated as
owners of the Ordinary Shares underlying such ADSs.
 
    The summary does not address the UK tax consequences to an Eligible US
Holder that is resident (or in the case of an individual, resident or ordinarily
resident) for United Kingdom tax purposes in the United Kingdom or that carries
on business in the United Kingdom through a branch or agency. Such a holder may
be subject to UK tax upon a disposition of Ordinary Shares or ADSs.
 
GENERAL
 
    When the Company pays a dividend on the Ordinary Shares, the Company is
required to account to the United Kingdom Inland Revenue (the "Inland Revenue")
for advance corporation tax ("ACT"). The ACT rate is one-fourth of any dividend
paid after April 5, 1994 (the equivalent of 20% of the  


                                       9
<PAGE>
dividend and the ACT). Based on the laws and practice of the United Kingdom, 
under the provisions of the income tax convention between the United Kingdom 
and the United States (the "Income Tax Convention"), an Eligible US Holder 
will be entitled to receive from the Company at the same time as and together 
with any dividend paid by the Company on the Ordinary Shares, an ACT-related 
tax credit less a withholding tax ("UK Withholding Tax") currently equal to 
15% of the aggregate of such credit and such dividend (the amount of such 
extra cash payment is referred to herein as a "Tax Treaty Payment"). For 
dividends paid after April 5, 1994, the ACT-related tax credit is an amount
equal to 20% of the sum of the dividend plus the ACT-related tax credit.
 
    Thus, for example, receipt by an Eligible US Holder of a dividend of $80
paid after April 5, 1994 will entitle the Eligible US Holder to receive a Tax
Treaty Payment of $5 (an ACT-related tax credit of $20 less a UK withholding Tax
of $15) resulting in a net receipt after UK taxes but before US taxes of $85.
 
    An Eligible US Holder is a record holder of ADRs that (i) is a citizen or
resident of the United States or that otherwise will be subject to US Federal
income tax on a net income basis in respect of the Ordinary Shares, (ii)
qualifies for the benefits provided by the Income Tax Convention for certain
recipients of dividend income and (iii) is entitled to use the arrangement
described below (the "Arrangement") under which the Tax Treaty Payment is paid
together with the associated dividend payment. See "An Arrangement for Direct
Receipt of Tax Treaty Payment".
 
QUALIFICATION FOR INCOME TAX CONVENTION BENEFITS
 
    A shareholder will be entitled to the benefits of the Income Tax Convention
(and therefore will be entitled to receive Tax Treaty Payments) if it is a
resident of the United States for the purposes of the Income Tax Convention and
it derives and beneficially owns the dividend payable in respect of the Ordinary
Shares, unless:
 
        (i) its holding is effectively connected with either (a) a permanent
    establishment situated in the United Kingdom through which the shareholder
    carries on business in the United Kingdom or (b) a fixed base in the United
    Kingdom from which the shareholder performs independent personal services;
    or
 
        (ii) in the case of a shareholder that is a US corporation, the
    shareholder (a) is a resident of the United Kingdom or (b) is a US
    corporation at least 25% of the capital of which is held, directly or
    indirectly, by persons that are not individual residents or nationals of the
    United States, and (x) which has imposed on it by the United States in
    respect of the dividend a tax substantially less than the tax generally
    imposed by the United States on corporate profits, or (y) which receives
    more than 80% of its gross income from sources outside the United States as
    determined in accordance with the Income Tax Convention.
 
    For these purposes, a partnership, an estate or a trust is a resident of the
United States only to the extent that the income derived by the partnership,
estate or trust is subject to US Federal tax as the income of a resident, either
in its hands or in the hands of its partners or beneficiaries, as the case may
be.
 
    Special rules may apply if the shareholder (i) is exempt from tax in the
United States on dividends paid by the Company, (ii) is a US corporation which
controls, alone or with one or more associated corporations, at least 10% of the
voting stock of the Company or (iii) owns 10% or more of the Ordinary Shares,
and investors subject to those special rules are not Eligible US Holders for
purposes of this discussion.
 
AN ARRANGEMENT FOR DIRECT RECEIPT OF TAX TREATY PAYMENT
 
    An Arrangement has been entered into with the Inland Revenue (based on the
"H" Arrangement, which is the usual administrative procedure operated in respect
of dividends paid on shares of UK companies represented by ADRs) under which a
shareholder that satisfies the additional requirements set forth in the next
sentence, will receive the Tax Treaty Payment to which it is entitled directly
from the Company rather than from the Inland Revenue at the same time as and 
together with the payment of the associated cash dividend, without the need 
for any additional action on its part.


                                       10
<PAGE>

    The additional requirements are that (a) the shareholder must be liable for
US Federal income tax on such dividends, (b) if the shareholder is an estate or
trust, all of the beneficiaries must be resident in the United States, (c) the
shareholder must not be engaged in business or performing independent personal
services through a permanent establishment or fixed base in the United Kingdom
and (d) if a shareholder is a corporation that is an investment or holding
company, 25% or more of its capital must not be owned directly or indirectly by
persons who are not individual residents or nationals of the United States.
 
    The Tax Treaty Payment is payable by the Company to an Eligible US Holder at
the same time as and together with the payment of the associated cash dividend
only pursuant to the Arrangement, and references in this Form 20-F to any Tax
Treaty Payment that may be payable by the Company should be construed
accordingly. A shareholder that is entitled to the Tax Treaty Payment but is not
eligible to receive the Tax Treaty Payment directly from the Company pursuant to
the Arrangement, may obtain the Tax Treaty Payment by making an individual claim
to the tax authorities, within six years of the end of the UK chargeable year in
which the related dividend was paid to the tax authorities for payment of that
amount at a later date. The claim for payment must be made in the manner and at
the times described in US Revenue Procedure 80-18, 1980-1 CB 623, and US Revenue
Procedure 81-58, 1981-2 C.B. 678. The first claim by a US shareholder for a
payment under these procedures is made by sending the appropriate UK form FD 13
in duplicate to the Director of the Internal Revenue Service Center with which
such US shareholder's last US Federal income tax return was filed.
 
    Forms may be obtained from the Foreign Operations District, Internal Revenue
Service, Assistant Commissioner (International), 950 L'Enfant Plaza South, SW,
Washington, DC 20024, Attention: Taxpayers' Service. Because a claim is not
considered made until the UK tax authorities receive the appropriate form from
the Internal Revenue Service, forms should be sent to the Internal Revenue
Service well before the end of the applicable limitation period. Any claim after
the first claim by a US shareholder for payment under these procedures should be
filed directly with the UK Inspector of Foreign Dividends, Fitz Roy House, PO
Box 46, Nottingham, England NG2 1BD.
 
TAXATION OF DIVIDENDS
 
    An Eligible US Holder will realize dividend income for US Federal income tax
purposes in an amount equal to the sum of any cash dividend paid by the Company
and the ACT-related tax credit, without reduction for the UK Withholding Tax
thereon. Such dividend income will generally not be eligible for the dividends
received deduction. Subject to certain limitations, the UK Withholding Tax will
be treated as a foreign income tax that may be claimed as a credit against the
US Federal income tax liability of an Eligible US Holder. The dividend income
will, for the purposes of computing the foreign tax credit allowable under the
Code, constitute income from sources without the United States, but with certain
exceptions, will be treated separately together with other items of "passive" or
"financial services" income.
 
TAXATION OF CAPITAL GAINS
 
    Eligible US Holders that are not resident or ordinarily resident in the
United Kingdom for UK tax purposes will not be liable for UK tax on capital
gains realized on the disposition of ADSs unless the holder carries on a trade,
profession or vocation in the United Kingdom through a branch or agency or, in
the case of a trade, a permanent establishment and the Shares are used in or for
the purposes of the trade, profession or vocation or are used, held or acquired
for the purposes of the branch or agency or, in the case of a trade, the
permanent establishment.
 
    An Eligible US Holder will realize a gain or loss for US Federal income tax
purposes on the sale or exchange of an ADS in the amount of the difference
between the amount realized and the Eligible US Holder's adjusted tax basis in
the ADS. Such gain or loss will be a capital gain or loss if the ADS was held as
a capital asset.

UNITED KINGDOM INHERITANCE ACT

    Under the current double estate and gift taxation convention between the US
and the UK, Ordinary Shares held by an individual shareholder who for the
purpose of the convention is domiciled in 
                                       11
<PAGE>
 
the US and is not domiciled in the UK nor a UK national at the date of death 
or disposition, as the case maybe, will not, provided any tax chargeable in 
the US is paid, be subject to UK inheritance tax on the disposition of shares 
by way of gift or upon the individual's death unless the shares are part of 
the business property of a permanent UK establishment of the individual or, in 
the case of a shareholder who performs independent personal services, pertain 
to a fixed base situated in the UK. In the exceptional case where the shares 
are subject both to UK inheritance tax and to US Federal gift or estate tax, 
the convention generally provides for double taxation to be relieved by means 
of credit relief.
 
UNITED KINGDOM STAMP DUTY RESERVE TAX AND STAMP DUTY
 
    Provided that the instrument of transfer is not executed in the United
Kingdom and remains at all times outside the United Kingdom, no UK stamp duty
will be payable on the acquisition or transfer of ADSs. Neither will an
agreement to transfer ADSs in the form of ADRs give rise to a liability to stamp
duty reserve tax.
 
    Purchases of Ordinary Shares, as opposed to ADSs, will normally give rise to
UK stamp duty or stamp duty reserve tax at the rate of 50p per B.P.100 (or part
thereof) of the price payable for the Ordinary Shares at the time of the
transfer. This will continue when paperless transfers are introduced under CREST
in July 1996. Where Ordinary Shares are transferred to the Depositary or its
nominee, the only charge will generally be the higher charge of B.P.1.50 per
B.P.100 (or part thereof) of the market value of the Ordinary Shares so
transferred.
 
ITEM 8. SELECTED CONSOLIDATED FINANCIAL DATA
- --------------------------------------------
 
    The selected consolidated financial data below has been derived from the
audited Consolidated Financial Statements of ASH, which have been examined by
ASH's independent auditors Binder Hamlyn, Chartered Accountants. The selected
consolidated financial data should be read in conjunction with, and are
qualified in their entirety by reference to, the Consolidated Financial
Statements and Notes thereto included elsewhere in this Form 20-F.
 
    ASH's Consolidated Financial Statements are prepared in accordance with
accounting principles generally accepted in the United Kingdom ("UK GAAP"),
which differ in certain significant respects from accounting principles
generally accepted in the United States ("US GAAP"). In making commercial
decisions on various transactions, including acquisitions and dispositions,
management considered the presentation of these transactions in its Consolidated
Financial Statements under UK GAAP. If the Group had reported its financial
results in accordance with US GAAP, management may have made different
commercial decisions on such transactions or may have structured such
transactions differently. A summary of the significant differences between UK
GAAP and US GAAP relevant to ASH, together with reconciliations of net income
and shareholders' equity, are set forth in Note 28 of Notes to Consolidated
Financial Statements.
 
    In October 1993, the UK Accounting Standards Board issued Financial
Reporting Standard No.3 ("FRS3") which prescribed a new format for the profit
and loss account, introduced a new primary statement, "The Statement of Total
Recognized Gains and Losses", and changed the basis of the calculation of
earnings per share. Items previously treated as extraordinary are now generally
treated as exceptional items within profit on ordinary activities before
taxation, resulting in large year on year variations in the level of income.
FRS3 also defines a discontinued business as an operation which is clearly
distinguishable, the disposal or termination of which has a material effect on
the nature and focus of the Group's activities, represents a material reduction
in the Group's operating facilities and is completed prior to the earlier of
three months from the balance sheet date or the date of approval of the UK
financial statements. The financial statements have been prepared in accordance
with FRS3.
 
    UITF Abstract 13 was issued on June 8, 1995 and is effective for financial
statements ending on or after June 22, 1995. This Abstract requires ESOP debtors
to be reclassified as investments and for any permanent diminution in value to
be charged to the profit and loss account. The financial statements have been
prepared in accordance with UITF Abstract 13.

(2) The calculation of net income per Ordinary Share in accordance with UK GAAP
    is based on the total net income including discontinued operations and the
    weighted average number of Ordinary Shares outstanding during the year, as
    adjusted for a one-for-forty eight bonus issue in July 1994 (1991: 112.9
    million, 1992: 115.0 million, 1993: 116.5 million, 1994: 119.5 million and
    1995: 119.6 million) and after taking account of preference share dividends
    (1991:B.P.3,005,000, 1992: B.P.2,874,000, 1993: B.P.2,844,000, 1994:
    B.P.2,839,000 and 1995: B.P.2,839,000 million).
 
(3) Operating income from continuing operations under US GAAP represents income
    before net interest expense, including results of related companies,
    exceptional items and in 1994 the provision against the investment in Arius
    of B.P.20.1 million. See Note 28 of Notes to Consolidated Financial
    Statements.
 
(4) The calculation of net income per Ordinary Share in accordance with US GAAP
    is based on the weighted average number of Ordinary Shares outstanding
    including common stock equivalents during the year (1991: 112.9 million,
    1992: 136.6 million, 1993: 116.5 million, 1994: 119.5 million and 1995 119.6
    million) and adjusted to take account of Preference Share dividends and the
    one-for-forty eight bonus issue in July 1994. Under US GAAP the net income
    (loss) from discontinued operations represents the results of the loss
    prevention businesses and the profit on sale of these operations in 1992.
    Net income (loss) from continuing operations represents the results of all
    other operations. See Note 28 of Notes to Consolidated Financial Statements.
 
(5) Long Term Debt includes 1991: B.P.57.9 million, 1992: B.P.43.5 million,
    1993: B.P.43.6 million, 1994: B.P.43.7 million and 1995: B.P.43.8 million in
    respect of the net amount of Convertible Capital Bonds. Long term debt
    includes 1991: B.P.33.8 million; 1992: B.P.35.6 million, and 1993: B.P.32.4
    million in respect of the Stapled Units, and in 1994: B.P.35.0 million and
    1995: B.P.36.7 million in respect of the 8.28% Senior Notes.
 
(6) Shareholders' funds, calculated in accordance with UK GAAP, include the 5%
    and 6% Convertible Cumulative Redeemable Preference Shares which aggregated
    B.P.51.9 million in 1991, B.P.49.3 million in 1992, B.P.48.7 million in
    1993, B.P.48.6 million in 1994 and B.P.48.6 million in 1995. Ordinary
    shareholders' equity, calculated in accordance with US GAAP, does not
    include such amounts. See Note 28 of Notes to Consolidated Financial
    Statements.
 
DIVIDENDS
 
    Any interim dividend on the Company's Ordinary Shares is normally declared
by the Board of Directors in July of each year and paid in December. A final
dividend may be recommended by the Board of Directors in March following the end
of the financial year to which it relates and, after approval by the
shareholders at the Annual General Meeting in April, is usually paid in June.
 
    The following table sets forth the amounts of interim, final and total
dividends paid on each Ordinary Share in respect of each financial year
indicated, increased by ACT but before deduction of UK withholding tax (both as
described under Item 7. "Taxation of Dividends"), and translated into US dollars
per ADS (each ADS representing two Ordinary Shares) at the Noon Buying Rate on
each of the respective payment dates.

    It is the intention of the Board to adopt a dividend policy which is closely
linked to the future growth of the continuing businesses.
 
    The payment of future dividends will depend upon the Group's earnings,
financial condition and such other factors as the Board of Directors deems
relevant. It should be noted that the Company is unlikely to be in a position to
pay dividends to Preference or Ordinary shareholders for the time being.

ITEM 9. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
- -------------------------------------------------------------------------------
OF OPERATIONS
- -------------
 
    The following discussion and analysis is based on the Consolidated Financial
Statements of the Group prepared in accordance with UK GAAP. The principal
differences between UK GAAP and US GAAP as they relate to the Group are
discussed in Note 28 of Notes to Consolidated Financial Statements. In making
commercial decisions on various transactions, including acquisitions and
dispositions, management considered the presentation of these transactions in
its Consolidated Financial Statements under UK GAAP. If the Group had reported
its financial results in accordance with US GAAP, management may have made
different commercial decisions on such transactions or may have structured such
transactions differently.
 
GROUP OVERVIEW
 
    Over the last three years the results of ASH have been adversely affected by
the difficult trading conditions in both of its primary markets. In 1995 there
has been a gradual improvement in trading conditions in the UK but the economic
climate in California remains difficult.
 
FISCAL 1995 COMPARED WITH FISCAL 1994
 
    In 1995 the Group reported a reduction in revenues of 1.7% from B.P.166.1
million to B.P.163.3 million. The 1995 results included B.P.9.6 million of
income from discontinued operations compared with B.P.11.8 million from these
operations in 1994. Consequently the underlying movement in revenues from
continuing operations was a slight reduction of 0.4% from B.P.154.3 million in
1994 to B.P.153.7 million in 1995, principally as a result of a 3.6% adverse
impact from the UK sterling to US dollar exchange rate. Within continuing
operations there was a growth in recurring rental and maintenance revenues with
a 1.1% improvement from B.P.81.5 million in 1994 to B.P.82.4 million in 1995.
Recurring revenues of the Group now represent some 54% of total income.


 
                                       15
<PAGE>
    In the UK and Eire revenues from continuing operations increased during the
year by 1.0% to B.P.111.9 million. Recurring revenues in the UK and Eire
continue to represent some 50% of total revenues.
 
    In the US, revenues remained constant at $66.2 million. Installation sales
increased by 0.4% to $24.8 million (1994: $24.6 million) with recurring revenues
decreasing by 0.7% to B.P. $41.4 million (1994: $41.8 million).
 
    Income before interest, exceptional items and taxation reduced by
approximately B.P.2.2 million from B.P.23.9 million in 1994 to B.P.21.7 million
in 1995. Discontinued operations reported losses of B.P.0.3 million in 1994 and
profits of B.P.1.4 million in 1995. Income before interest, exceptional items
and taxation from continuing operations consequently reduced by B.P.4.0 million
(16.5%) from B.P.24.2 million in 1994 to B.P.20.2 million in 1995.
 
    Operating profits in UK and Eire reduced by 3.4% to B.P.18.4 million as a
result of trading losses in Telecom Security, Eire and TVX together with a
disappointing first half performance of the UK Sonitrol franchise, which
contributed B.P.0.5 million in 1995 compared with B.P.1.3 million in the
previous year. Results in the core business, Modern Security Systems, improved
by 2.6% to B.P.19.6 million on increased revenues of B.P.91.4 million at a
margin of 21.4%,which is consistent with the prior year.
 
    Operating profits in the US fell by 13.2% to $10.0 million (1994: $11.5
million). Profits in API fell by 9.9% to $6.0 million, primarily due to the sale
of the residential portfolio in the previous year. The result of Sonitrol
Management Corporation was adversely impacted by an indifferent trading
performance together with increased communication facility costs.
 
    Discontinued operations relate to Modern Vitalcall Limited and Integrated
Systems operations in the UK and two related companies, Compagnie Generale de
Protection et Securite SA in France and Microtech Security (UK) Limited in the
UK. During 1995 these operations produced B.P.1.4 million of operating profit
compared to full year profit in 1994 of B.P.2.1 million which, combined with the
loss on discontinued operations from prior years of B.P.2.4 million, produced a
net loss in 1994 of B.P.0.3 million.
 
    The principal components of exceptional items in 1995 were the sale of
discontinued operations, additional charges at API Security, refinancing costs
and amounts written off in respect of the Employee Share Ownership Plan (ESOP).
Details of these exceptional charges are set out as follows.
 
    In September 1995 ASH concluded the disposal of Modern Vitalcall Limited, a
wholly owned subsidiary, for B.P.1.5 million. In addition, the Group sold its
remaining Integrated Systems business in November 1995 for B.P.2.4 million. ASH
also disposed of its shareholdings in two associated undertakings, Compagnie
Generale de Protection et Securite SA (France) for B.P.4.4 million and Microtech
Security (UK) Limited for B.P.1.0 million. These four disposals realised B.P.9.3
million but resulted in a charge to the Profit and Loss account of approximately
B.P.5.7 million, compensated for by a write back to reserves in respect of
goodwill written off of B.P.8.8 million.
 
    To enhance the generation of cash and profit in API Security, the Board
approved a move to smaller and less expensive premises on the expiry of the
present lease in May 1996 and the implementation of enhanced computer monitoring
and business systems. As a consequence the Group has written off the cost of
existing leasehold improvements and computer systems of B.P.2.4 million.
 
    During 1995 the Group has incurred external refinancing costs of
professional advisers relating to assessing the various options to restructure
the Balance Sheet and thus improve shareholder value. In 1995 these costs
amounted to B.P.3.1 million (1994: B.P.1.6 million).
 
    UITF Abstract 13 was issued on June 8, 1995 and is effective for UK
financial statements ending on or after June 22, 1995. This Abstract requires
ESOP receivables to be reclassified as investments and for any permanent
diminution in value to be charged to the Profit and Loss account. The Board
believe that a prudent method of application of this Abstract is to value the
stock held by the ESOP at market price as at November 30, 1995. As a result, the
shortfall between the market value of the ESOP's stock and the amount receivable
from the ESOP has been charged to the Profit and Loss account in 1995. The
 
                                       16
<PAGE>
amount provided in earlier years (1994: B.P.450,000; 1993: B.P.200,000) has also
been reclassified as an exceptional item in the results for those years.
 
    The net charge for exceptional items in 1994 of B.P.23.2 million related to
a write off of B.P.20.2 million in respect of the investment in Arius Inc,
B.P.450,000 in respect of the ESOP, refinancing costs of B.P.1,582,000 and
B.P.993,000 paid to the former Chairman and Chief Executive.
 
    Net interest charges were higher in 1995 at B.P.14.9 million (1994: B.P.12.5
million). This was due to an increase in bank margin and higher interest rates
in the UK and USA.
 
    The tax charge for 1995 was B.P.0.8 million compared to B.P.1.0 million for
the previous year. The tax charge in both 1995 and 1994 comprises mainly Advance
Corporation Tax (ACT) resulting from the preference dividends accrued or paid in
the year. ACT is presently deemed irrecoverable, although it is available for
offset against future UK mainstream corporation tax liabilities. ACT has been
accrued in full even though dividends of B.P.1,233,000 in respect of the 6%
Preference Shares for the six months to November 1995 have not been paid during
the year but have been accrued in these financial statements. Accrued ACT
written off in 1995 amounted to B.P.355,000. Based on current projections no
provision is required for deferred tax under UK accounting practice.
 
    The net loss reduced from B.P.12.8 million in 1994 to B.P.8.2 million in
1995 primarily due to the benefit of a reduction in exceptional items of B.P.9.0
million, from B.P.23.2 million in 1994 to B.P.14.2 million in 1995 offset by a
reduction in operating profits from continuing operations of B.P.4.0 million and
an increase in profits from discontinued operations of B.P.1.7 million. Net
interest charges increased by B.P.2.3 million but taxation charges reduced by
B.P.0.2 million.
 
    After deduction of Preference Share dividends of B.P.2.8 million in 1995 and
1994, the net loss attributable to ordinary shareholders was B.P.11.0 million in
1995 compared to loss of B.P.15.6 million in 1994. The loss per Ordinary Share
in 1995 was 9.2p compared to a loss of 13.0p per share in 1994.
 
FISCAL 1994 COMPARED WITH FISCAL 1993
- -------------------------------------
 
    In 1994 the Group achieved an overall growth in revenues of 3.3% from
B.P.160.8 million to B.P.166.1 million. The results included income from
discontinued operations of B.P.11.8 million in 1994 compared with B.P.17.6
million in 1993 and consequently the underlying growth in revenues from
continuing operations was 7.8% from B.P.143.1 million in 1993 to B.P.154.3
million in 1994. The growth in recurring rental and maintenance revenues was
significant with a 4.4% improvement from B.P.78.7 million in 1993 to B.P.82.2
million in 1994. Recurring revenues of the Group represented some 53.3% of total
income.
 
    In the UK and Eire revenues from continuing operations increased during the
year by 11.1% to B.P.110.8 million. The growth in recurring revenues of 10.6% to
B.P.54.8 million was helped by the first full year's trading of Telecom Security
("TSL") within the Group. Recurring revenues in the UK and Eire represented
49.5% of total revenues.
 
    In the US, revenues increased by 1.5% from $65.5 million to $66.4 million
but on conversion to sterling revenues remained constant at B.P.43.5 million.
Installation sales increased by 13.8% to $24.7 million (1993: $21.7 million)
with recurring revenues decreasing by 4.7% to $41.8 million (1993: $43.8
million). The fall in recurring revenues reflected the difficult Californian
economic climate and the move by some customers from rental to outright sale.
 
    Income before interest, exceptional items and taxation increased by
approximately B.P.4.3 million from B.P.19.6 million in 1993 to B.P.23.9 million
in 1994. Discontinued operations reported losses of B.P.3.6 million in 1993 and
B.P.0.3 million in 1994. Income before interest, exceptional items and taxation
from continuing operations consequently increased by B.P.0.9 million (4.1%) from
B.P.23.3 million in 1993 to B.P.24.2 million in 1994.
 
    Operating profits of the principal operating companies in the UK and Eire
reduced by 1.9% to B.P.19.0 million. Results in the core business, Modern
Security Systems, continued to improve but the results were adversely affected
by the disappointing results in both Eire and TSL. Management changes have taken
place in both operations in 1995.
 
                                       17
<PAGE>
    Operating profits of the principal operating companies in the US increased
by 0.5% from $11.4 million to $11.5 million but fell slightly on conversion to
sterling by 1% to B.P.7.5 million (1993: B.P.7.6 million). The profit on the
sale of the API residential portfolio of B.P.1.0 million was offset by abortive
acquisition costs and the costs of closing the Florida office. The results of
Sonitrol Management Corporation were adversely impacted due to the higher
element of lower margin outright sale business compared with 1993. This was
compensated for by improved margins as a result of reduced operating costs in
API.
 
    Operations discontinued during 1994 relate to Modern Integrated Systems. The
1994 loss of B.P.2.4 million is a result of project overrun costs, increased
provisions for warranty work and a significant downgrade on contract realization
values. In addition, operations discontinued during 1995 have also been restated
as discontinued operations in 1994 and 1993. These businesses produced operating
profits of B.P.2,121,000 in 1994 and B.P.1,332,000 in 1993. Consequently
restated losses from discontinued operations amounted to B.P.0.3 million in 1994
and B.P.3.6 million in 1993.
 
    The final result for 1994 was impacted severely by exceptional items. The
principal component of exceptional items in 1994 relates to the provision
against the investment in Arius Inc, a related company, where the Group had a
significant shareholding. The Board had taken the decision to dispose of this
holding since it was not regarded as part of continuing core activities.
However, the announcement by Arius that it was experiencing a number of serious
financial and trading difficulties caused the Board to feel that, as a matter of
prudence, it was right to provide against the full carrying value of the
investment, together with all potential liabilities and to write off the value
of goodwill with respect to Arius previously taken to non-distributable
reserves. The effect of this decision was to write off B.P.20.2 million ($30.8
million) to the profit and loss account. Arius Inc subsequently filed for
protection under Bankruptcy Code, Chapter 7, on May 8, 1995. Exceptional items
in 1994 also include a payment to the former Chairman and Chief Executive of
B.P.993,000, refinancing costs of B.P.1,582,000 and a provision of B.P.450,000
in respect of the ESOP. The charge for exceptional items in 1993 related to
B.P.1.4 million for the fundamental reorganization and restructuring in the UK
and B.P.200,000 in respect of the ESOP.
 
    Interest charges were higher in 1994 at B.P.12.5 million (1993: B.P.10.7
million). This was due to a significant increase in international interest rates
and a move from US dollar to sterling borrowings to simplify the Group's
currency hedging arrangements.
 
    The tax charge for 1994 was B.P.1.0 million compared to B.P.1.8 million for
the previous year. The tax charge in both 1994 and 1993 comprises mainly Advance
Corporation Tax (ACT) resulting from the payment of preference dividends in 1994
and both preference and ordinary dividends in 1993. ACT is presently deemed
irrecoverable, although it is available for offset against future UK mainstream
corporation tax liabilities. The tax charge for 1993 was reduced due to the
payment of scrip dividends to Ordinary Shareholders. Based on projections no
provision was required for deferred tax.
 
    Net income decreased from B.P.5.5 million in 1993 to a net loss of B.P.12.8
million in 1994 primarily due to the impact of the provision against the
investment in Arius Inc of B.P.20.2 million. After deduction of preference share
dividends of B.P.2.8 million in 1994 and 1993, the net (loss)/income
attributable to ordinary shareholders was a loss of B.P.15.6 million in 1994
compared to a profit of B.P.2.7 million in 1993. The loss per Ordinary Share in
1994 was 13.0p compared to a profit of 2.3p per share in 1993. Adjusted earnings
per Ordinary Share prior to the amount written off the investment in Arius Inc
were 3.8p per share in 1994.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    At November 30, 1995 the Group had three main sources of debt funding: bank
facilities, including a committed Multiple Option Loan Facility (the "MOF"),
Senior Notes and Convertible Capital Bonds.
 
    In May 1989, the Company entered into the MOF with a group of United Kingdom
and international banks led by Lloyds Bank PLC, which was originally fully
underwritten for B.P.90 million
 
                                       18
<PAGE>
until May 1994 and B.P.70 million until May 1995. The acquisition of API
Security in August 1989 for $105 million was funded by drawings under the MOF.
 
    In September 1990, API Security Inc. issued stapled units of 10.73%
Guaranteed Subordinated Serial Notes (the "Stapled Units" issue) to The
Prudential Insurance Company of America for a total consideration of $60 million
(before expenses). The net proceeds of the Stapled Units issue were used to
repay dollar borrowings drawn under the MOF in connection with the acquisition
of API.
 
    In May 1991, the Company, through a finance subsidiary, issued B.P.60
million of 9.5% Convertible Capital Bonds due 2006 in the Euromarkets. The
proceeds of the issue were used to repay a portion of the Group's variable rate
sterling short to medium term borrowings.
 
    In 1992, the loss prevention businesses were sold for B.P.153 million which
enabled bank debt to be largely eliminated on receipt of the proceeds on July
30, 1992. In September 1992 the Company acquired Sonitrol and SMC for B.P.26
million. In addition some B.P.15 million of 9.5% Convertible Capital Bonds were
repurchased.
 
    In 1993 the Company acquired TSL for a consideration net of cash acquired of
B.P.4.7 million and repaid $6 million (B.P.3.9 million) in respect of the
Stapled Units.
 
    On May 27, 1994 the Company issued $60,721,638, 8.28% Senior Notes of which
$5,643,273 was in respect of yield maintenance. The Notes were originally due
for repayment on May 27, 1999. The Notes were issued to the Prudential Insurance
Company of America to replace the Stapled Units previously issued by API
Security Inc.
 
    At November 30, 1994 bank debt (net of cash) was broadly unchanged when
compared with 1993 at B.P.79 million. In addition, the total amount outstanding
under the Loan Notes and the Convertible Capital Bonds at B.P.78.7 million, was
also unchanged.
 
    At November 30, 1995 the Group had available bank facilities totalling
approximately B.P.89.0 million, of which approximately B.P.83.4 million were
committed, including B.P.66.3 million under the MOF. ASH had short term debt of
approximately B.P.83.1 million at November 30, 1995 (1994: B.P.82.6 million) and
long term debt outstanding, excluding the B.P.43.8 million (1994: B.P.43.7
million) of Convertible Capital Bonds, of B.P.0.4 million (1994: B.P.Nil).
 
    On December 21, 1995, the Group reached agreement ("the Credit Agreement")
with its principal bankers to extend the majority of the Group's committed
facilities of B.P.83.4 million through January 2, 1998. This new facility
consolidates the B.P.66.3 million previously available under the MOF facility
and the majority of the B.P.17.1 million previously available from bilateral
facilities. Additionally the Group had uncommitted overdraft and working capital
lines at November 30, 1995 totalling in excess of B.P.5.6 million. The terms of 
the 8.28% Senior Notes were also amended by agreement with the Prudential 
Insurance Company of America on December 21, 1995. The maturity date of the 
Senior Notes has also been amended to January 2, 1998, and the terms of the 
Senior Notes and the bank facilities are treated on an equivalent basis. As 
part of the aforementioned agreement with the Group's principal bankers and the
Prudential Insurance Company of America, the Group's indebtedness under the 
Credit Agreement and to the holders of the Senior Notes is secured by pledges 
over the majority of the assets of the Group.
 
    A significant proportion of the Group's assets are held in the United
States. The Group manages its exposure to fluctuations in US dollar exchange
rates by borrowing US dollars. The amount hedged includes all US net assets as
calculated under UK GAAP together with an element of goodwill. Exchange
movements on assets including goodwill and borrowings are offset in reserves.
 
    During 1995 the Group disposed of a number of peripheral businesses so as to
reduce debt and enable the Group to focus on its core businesses, in the UK,
Modern Security Systems and TSL, and in the US, API and Sonitrol, to ensure 
positive trading cash flows to reduce debt and increase shareholders' funds. 
The Board continues to address the high level of gearing as priority and during
1995 the Group incurred significant costs relating to the various options to

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

OPTION SCHEMES
 
    Share Option Scheme. Under the terms of the Share Option Scheme (the
"Scheme"), full time directors and employees of the Company and its subsidiaries
may participate in the Scheme at the discretion of the Board of Directors. The
Scheme involves a participant being granted an option to subscribe for Ordinary
Shares at the higher of the nominal value and the market price of such Ordinary
Shares at the time of grant. Except in certain circumstances, options may not be
exercized before the third or on or after the tenth anniversary of their grant.
A participant may not hold options at any one time such that the aggregate
market value (calculated at the time of grant) of the Ordinary Shares which may
be acquired on the exercise of such options would exceed four times his annual
remuneration. The consideration for the grant of an option may not exceed B.P.1.
As of March 30,1996, a total of 1,804,192 Ordinary Shares were subject to option
under the Scheme at subscription prices between 130p and 269.3p per share,
exercizable by March 29, 2003.
 
    ESOP Executive Share Option Scheme. The ESOP Executive Share Option Scheme
(the "Executive Scheme") is divided into Part A, relating to options approved by
the United Kingdom Inland Revenue, and Part B, relating to unapproved options.
Under the terms of Part A, full time directors and employees of the Company and
its subsidiaries may participate at the discretion of the Board of Directors.
Under the terms of Part B, all directors and employees of the Company and its
subsidiaries may participate at the discretion of the Board of Directors. Part A
options qualify for special tax relief under the UK Income and Corporation Tax
Act of 1988 and may not be exercized before the third or after the tenth
anniversary of their grant. Part B options do not qualify for such tax relief
and may not be exercized before the third or after the seventh anniversary of
their grant. The Part A options are included with the options granted under the
Share Option Scheme when determining the total number of options which may be 
held by a participant at any one time as described above. The total number of 
Part B options which may be held at any one time are subject to a separate 
limit such that the aggregate 
 
                                       21
<PAGE>
market value (calculated at the time of grant) of the Ordinary Shares which 
may be acquired on the exercise of such options may not exceed four times a 
participant's annual remuneration.
 
    As of March 30, 1996, a total of 772,000 Ordinary Shares were subject to
option under the Executive Scheme at subscription prices between 245p and 269.3p
per share, exercizable by April 30, 2000.
 
    Sharesave Scheme 1993. ("The Sharesave Scheme") UK Resident directors and
employees of the Company and its subsidiaries may participate in the Scheme with
the qualifying length of service being at the discretion of the Board of
Directors. The scheme involves the participants entering into an Inland Revenue
approved savings contract with contracted savings of between B.P.10 and B.P.250
per month over 5 years. Options are granted at the time of entry to the
Sharesave Scheme to subscribe for Ordinary Shares at the higher of the nominal
value and 80 per cent of the middle market value of such shares on a specified
date on which invitations to apply for options are issued. Except in certain
circumstances, options may only be exercized during the six month period
commencing on the fifth anniversary of the commencement of the related savings
contract.
 
    As of March 30, 1996 a total of 337,668 Ordinary Shares were subject to
option under the Sharesave Scheme at a subscription price of 128p per share,
exercisable by October 1, 1998.
 
    Executive Share Option Scheme 1993. At the Annual General Meeting held April
29, 1993 the shareholders approved the introduction of the Executive Share
Option Scheme 1993 ("The 1993 Executive Scheme"). The terms of the 1993
Executive Scheme are broadly in line with the terms of the Share Option Scheme
set out above with the exception that under the 1993 Executive Scheme up to one
quarter of the grants made may be at a price which is 85 per cent of the middle
market price on a day shortly before the date of the grant, provided that
certain Inland Revenue conditions are satisfied and that the resultant price is
equal to or exceeds nominal value. At March 30, 1996 no options had been granted
under the 1994 Executive Scheme.
 
    The following options were held by the Directors and officers as at May

                  REPORT OF INDEPENDENT CHARTERED ACCOUNTANTS
 
To the Board of Directors and Shareholders of
Automated Security (Holdings) PLC and subsidiaries
 
We have audited the accompanying consolidated balance sheets of Automated
Security (Holdings) PLC as of November 30, 1995 and 1994, and the related
consolidated statements of income, shareholders' equity and cash flows for each
of the three years in the period ended November 30, 1995; which, as described in
Note 1 have been prepared on the basis of accounting principles generally
accepted in the United Kingdom. These financial statements are the
responsibility of the management of Automated Security (Holdings) PLC. Our
responsibility is to express an opinion on these financial statements based on
our audit.
 
We conducted our audits in accordance with United Kingdom auditing standards
which do not differ in any significant respect from United States generally
accepted auditing standards. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
In our opinion, the consolidated financial statements set out on pages F-2 to
F-46, present fairly, in all material respects, the financial position of
Automated Security (Holdings) PLC at November 30, 1995 and 1994 and the results
of its operations and its cash flows for each of the three years in the period
ended November 30, 1995, in conformity with accounting principles generally
accepted in the United Kingdom which differ in certain significant respects from
those generally accepted in the United States.

               AUTOMATED SECURITY (HOLDINGS) PLC AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NATURE OF OPERATIONS
 
    Automated Security (Holdings) PLC is the holding company of a group
operating in the electronic security sector which designs, markets, installs,
maintains and monitors electronic security systems to safeguard life and
property from a wide range of hazards. The Group's principal markets are the
United Kingdom with some 73% of sales and the United States with 27% of sales.
Substantially all of the customers in the US and some 75% of customers in the UK
are in the commercial, industrial and public sectors. The balance of services
are provided in the private, residential sector.
 
1. SIGNIFICANT ACCOUNTING POLICIES
 
  Basis of financial statements
 
    As in previous accounting periods, the financial statements have been
prepared under United Kingdom generally accepted accounting principles using the
historical cost convention, with the exception that certain property has been
revalued.
 
  Consolidation
 
    The consolidated financial statements incorporate Automated Security
(Holdings) PLC ("Automated Security (Holdings)") and its subsidiaries (the
"Group") for the year ended November 30. When subsidiaries are acquired or
disposed of during an accounting period, unless they are accounted for as a
pooling-of-interest, the consolidated statement of income includes the results
only for that part of the period during which they are subsidiaries.
 
  Goodwill
 
    Goodwill, being the excess of the consideration on the acquisition of
businesses over the fair value of the net assets acquired, is written off direct
to non-distributable reserves at the date of acquisition.
 
  Investments
 
    Fixed asset investments, excluding related companies, are included at cost
less amounts provided where, in the opinion of the directors, there is a
permanent diminution in value.
 
    A company is treated as being a related company if, not being a subsidiary
company, the Group is in a position to exercise significant influence over the
company and the investment is considered to be long-term.
 
    The results and net assets of related companies are accounted for using the
equity method. Accordingly, the consolidated statement of income includes the
Group's share of income before taxes and taxes on income for the part of the
accounting period during which the companies are treated as related. Premiums on
the acquisition of related companies are written off to non-distributable
reserves at the date of acquisition.
 
    The amounts at which investments in related companies are included in the
consolidated balance sheet therefore comprise the cost of the investment less
premium on acquisition together with the Group's share of retained profits or
losses since the date of acquisition less any amounts provided where, in the
opinion of the directors, there is a permanent diminution in value.
 
  Development expenditure and distribution rights
 
    Expenditure on development and distribution rights is written off as it is
incurred.

1. SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)
  Inventories
 
    Inventories are valued at the lower of cost and net realizable value on the
FIFO basis. Cost of products manufactured and distributed by the Group consists
of direct material and labor costs,
together with appropriate overheads.
 
  Property and equipment
 
    The cost of equipment on contract hire installed by Group companies is
capitalized as an operating lease. Costs comprise materials, labor and
attributable overheads relating to identifiable and recoverable equipment. All
other costs are written off as they are incurred.
 
  Depreciation and amortization
 
    Property and equipment is depreciated on a straight line basis at the
following annual rates:
 
<TABLE>
<S>                                             <C>
Equipment on contract hire:
  Burglar alarms.............................   7%-10%
  Communication centre equipment.............   10%-20%
  Freehold buildings.........................   2.5%
  Leasehold premises and improvements........   over unexpired period of lease
  Motor vehicles.............................   25%
  Other assets...............................   10% to 33.3%
</TABLE>
 
    No depreciation is provided on freehold land.
 
  Equipment leased to customers
 
    Equipment leased to customers under finance leases is deemed to be sold at
normal selling value which is taken to net sales at the inception of the lease.
Debtors under finance leases represent outstanding amounts due under these
agreements less finance charges allocated to future periods. Finance lease
income is recognized over the primary period of the lease so as to produce a
constant rate of return on the net cash investments.
 
    Equipment leased to customers under operating leases is capitalized in
accordance with the accounting policy on property and equipment (see above).
Operating lease income is accounted for on a straight line basis with any rental
increases recognized during the period to which they relate.
 
  Operating Leases
 
    Rentals paid under operating leases are charged against income on a straight
line basis over the period of the lease.
 
  Deferred taxation
 
    Deferred taxation is provided on the liability method in respect of timing
differences between profits as computed for taxation purposes and profits as
stated in the financial statements except to the extent that it is expected that
the liability will not be payable in the foreseeable future. Timing differences
arise mainly from the excess of tax allowances on property and equipment over
the corresponding depreciation charged in the financial statements.

  Foreign exchange
 
    Foreign currency assets and liabilities of United Kingdom companies and the
financial statements of overseas subsidiaries and related companies are
translated into sterling at the rates of exchange ruling at the balance sheet
date. The results of overseas subsidiaries and related companies have been
translated at the average exchange rate ruling during the year with the
adjustment between average rates and the rates ruling at the balance sheet date
being taken to reserves. The differences arising from the translation of net
equity interests including goodwill in overseas subsidiaries and related
companies, and of matching foreign currency loans and foreign currency swap
facilities, are dealt with through reserves. All other exchange differences are
dealt with in the profit and loss account.
 
  Pensions
 
    The Group operates a funded defined benefit plan for UK employees, based on
final pensionable salary, with assets held in funds administered by the Trustees
of the plan. The cost of providing pensions is spread on a systematic and
rational basis over the period during which the Group benefits from the members'
services.
 
    The pension costs and any necessary provisions are assessed in accordance
with the advice of an independent qualified actuary. Variations from the regular
cost are spread over the average remaining service lives of current employees.
Outside the UK, the Group in general operates defined contribution plans for
certain executives, the costs of which are recognized on the basis of
contributions payable.
 
  Employees' Share Ownership Plan Trust
 
    The Group operates an Employees' Share Ownership Plan ("ESOP') Trust for
directors and employees. The ESOP Trust holds shares in the Company and is
financed by a loan from the Company. In prior years the net amount due from the
Trust was shown in other debtors but following the publication of UITF Abstract
13 in 1995, this balance is now classified as an investment in "own shares' and
the comparative figures have been restated accordingly.
 
    Provision is made for the diminution in the market value of the shares held
by the ESOP Trust.
 
  Earnings per share
 
    Earnings per ordinary share are calculated on a basic and fully diluted
basis. The basic calculation is based on total net income including discontinued
operations and the weighted average number of ordinary shares in issue during
the year.
 
    Adjusted earnings per ordinary share is calculated by dividing the net
income attributable to ordinary shareholders prior to the charge for the amount
written off fixed asset investments and the loss on sale of subsidiary and
related companies by the weighted average number of ordinary shares in issue
throughout the year. Adjusted earnings have been shown to illustrate the
earnings prior to these exceptional non-recurring charges.
 
  Use of estimates in the preparation of financial statements
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statement and the reported amounts of revenues and expenses during the reporting
period. Actual results could differ from those estimates.

2. RESTATEMENT OF PRIOR YEAR RESULTS
 
    The results of prior years have been restated in two respects to accord with
current accounting procedures. The results of the operations sold during 1995
have been reclassified as discontinued operations. Revenue from continuing
operations has therefore been reduced by B.P.11,768,000 in 1994 and
B.P.10,394,000 in 1993 and operating profit from continuing operations has been
reduced by B.P.2,121,000 in 1994 and B.P.1,332,000 in 1993.
 
    The amounts provided in respect of the ESOP of B.P.450,000 in 1994 and
B.P.200,000 in 1993 have also been reclassified in the comparative figures from
general and administrative expenses to exceptional items.
 
3. ACQUISITIONS
 
    There were no acquisitions of businesses during the year ended November 30,
1995.
 
    During the year ended November 30, 1994 the group acquired certain assets of
Sonitrol of Eugene in the United States for an initial cash consideration of
B.P.1,480,000($2,070,000) and a deferred consideration of B.P.289,000
($452,000).
 
    During the year ended November 30, 1993 the Group acquired Telecom Security
in the UK for an initial cash consideration of B.P.6.9 million and an accrued
future consideration of B.P.1.4 million.
 
    These companies are all in the Security Systems business and the
acquisitions were accounted for as purchases. The results of operations have
been included in the financial statements since their respective dates of
acquisition.

    The ESOP executive share option scheme (the 'Scheme') involves a participant
being granted an option to subscribe for Ordinary Shares of the Company at a
price based on the market price of such Ordinary Shares at the date of the
grant. All directors and employees of the Group may participate in the Scheme at
the discretion of the Board of directors. The maximum number of shares which may
be granted to any recipient is restricted by reference to a formula based upon
the annual remuneration of the individual director or employee. The options are
exercisable during a period between three and ten years after the date of the
grant (and in certain cases between three and seven years from the date of the
grant ) with the last date for such exercise varying between 1996 and 2000. The
prices at which the options are exercisable are in the range of B.P.2.45 per
share to B.P.2.693 per share. At November 30, 1995 there were 722,000 Ordinary
Shares subject to option under the Scheme.
 
    The costs of the ESOP have been met by the Trust and the ESOP has not waived
any dividends due on the Company's shares.

10. DIVIDENDS
 
    The Directors have not recommended payment of a dividend in respect of the
Ordinary Shares for 1995 or 1994. All of the preference dividends were paid for
1994 but in 1995 only the interim dividends have been paid on the due date. The
balance of the preference dividends has been accrued but it should be noted that
the Company is unlikely to be in a position to pay Preference or Ordinary
dividends to shareholders for the time being.

    (A) BANK LOANS
 
    At November 30, 1995 the Group had bank facilities totalling approximately
B.P.89.0 million, of which approximately B.P.83.4 million were committed
including B.P.66.3 million under the Multiple Option Facility which was
previously underwritten by the banks concerned until May 14, 1996. All of the
maturity dates of the committed facilities have been extended to January 2, 1998
by a Credit Agreement dated December 21, 1995 which gives security to the banks
over the majority of the assets of the Group. Of these facilities, the Group has
drawn down amounts in both pounds sterling and US dollars. The average rates of
interest charged in 1995 were 7.7% for sterling borrowings and 7.4% for US
dollar borrowings. All other loans are at variable rates of interest ranging
between 7% and 9 %. The average rate of interest paid on short term borrowings
during the year was 7.6% (1994: 5.2%; 1993: 5.0%).

    The Group had various hedging arrangements to offset any gains or losses on
the translation of net equity interest in overseas subsidiaries, principally in

November 30, 1993 to receive some B.P.18.2 million and an obligation to pay US
$35 million. The swap was cancelled on April 20, 1994. Gains and losses on the

    During 1994 the provision for cancelled contracts was transferred to
depreciation on equipment on contract hire in property and equipment. See note
8. The amounts shown above as provisions of B.P.1,060,000 in 1995 and
B.P.1,357,000 in 1994 are described as "provisions for liabilities and charges"
under UK GAAP.
 
14. DERIVATIVE FINANCIAL INSTRUMENTS
 
    As part of the Group's currency hedging arrangements discussed above the
company previously used a US dollar currency swap facility to manage its
exposure to fluctuations in US dollar exchange rates. This facility was repaid
in April 1994 and the Group no longer uses any derivative instruments for
currency hedging. US dollar assets are now matched using US currency loans and
the Group has no derivative financial instruments.

    Exceptional operating expenses in 1995 relate to refinancing costs of
B.P.3,136,000 and costs in API Security of B.P.2,348,000. Refinancing costs
relate to fees to professional advisers and other third parties in connection
with the refinancing of the Group. The additional charges at API Security relate
to the write off of existing computer systems and leasehold improvements of $3.7
million as a result of the Board's decision to move to smaller and less
expensive premises on expiry of the present lease in May 1996 and the
implementation of enhanced computer monitoring and business systems.
 
    The 1995 loss on the sale of discontinued operations relates to the sale of
a subsidiary undertaking, Modern Vitalcall Limited, the business of Modern
Integrated Systems and the Group's investment in two associated undertakings,
Compagnie Gnrale de Protection et Scurit SA and Microtech Security (UK) Limited.
The total consideration receivable amounted to B.P.9.3 million of which B.P.0.1
million is receivable in 1996 and B.P.0.5 million is in the form of Loan Notes.
 
    As part of the Company's share option schemes the group established the
Automated Security (Holdings) PLC Employees' Share Ownership Plan ('ESOP'). The
ESOP has a loan of B.P.5.9 million from the Company and its assets consist
principally of investments in the Company's shares.
 
    In accordance with Urgent Issues Task Force Abstract 13, issued on June 8,
1995, the amount receivable from the ESOP is reclassified as a fixed asset
investment (see note 7b) and any permanent diminution in value is charged to the
profit and loss account. The Board believes that a prudent method of application
of this Abstract is to value the shares held by the ESOP at the market prices as
at November 30, 1995. Consequently the shortfall between the market value of the
ESOP's shares and the amount receivable from the ESOP has been charged to the
profit and loss account in the current year. The provisions made in previous
years (1994: B.P.450,000 and 1993: B.P.200,000) have been reclassified as
exceptional items in the above analysis.

    In accordance with the Group's accounting policy no provision for deferred
taxation was required in 1993, 1994 or 1995. Permanent differences principally
related to the results of overseas operations which did not incur a tax charge
under UK GAAP.
 
    The total potential liability for deferred tax under UK GAAP is as follows:-

19. PENSIONS
 
    The Group operates a contributory defined benefits plan (the "Plan")
available for all full-time permanent employees in the UK who have attained the
age of 18. The benefits are related to final pensionable salary and pensionable
service. The amount charged for the Plan in the year ended November 30, 1995 was
B.P.1,181,000 (1994: B.P.1,160,000, 1993: B.P.1,098,000) net of member
contributions. Including member contributions the charge was B.P.1,772,000 in
1995, B.P.1,705,000 in 1994 and B.P.1,654,000 in 1993.
 
    The latest actuarial valuation of the plan was carried out at April 1, 1994
using the Projected Unit method, to assess the finances of the Plan and to
determine pensions costs. For the valuation, certain long term assumptions were
employed, the most important being:
 
        (i) Investment return: 8.5% per annum compound
 
        (ii) Dividend increases: average of 4.0% per annum
 
        (iii) Pensionable salary growth: 6.5% per annum compound
 
        (iv) Increases to pensions in payment in excess of GMP's: 0.7% per annum
    compound
 
        (v) Increases to deferred pensions: 5% per annum compound.
 
    At April 1, 1994, the market value of the assets of the UK Pension Fund was
B.P.30.2 million. The actuarial value of the assets amounted to 119% of the
value of the accrued liabilities of the Fund after allowing for the assumed
increases in pensionable salary. The surplus assets in the Fund are being used
to reduce the Group's long-term contributions to the Fund. The effect upon Group
profit is not significant. Overseas, the Group in general operates defined
contribution plans for certain executives, the costs of which are recognised on
the basis of contributions payable. The contributions in the year ended November
30, 1995 were B.P.382,000 (1994: B.P.557,000, 1993: B.P.705,000).
 
    The amount charged to income in respect of all pension plans was
B.P.1,563,000 in 1995, B.P.1,717,000 in 1994 and B.P.1,803,000 in 1993.
 
    Under UK GAAP, the cost of providing pension benefits may be calculated by
the use of any actuarial method which is appropriate and whose assumptions
reflect the long-term nature of the assets and liabilities involved. Under US
GAAP, the cost of providing these benefits are calculated in accordance with
Statement of Financial Accounting Standards No. 87 which requires the use of the
projected unit method and a discount rate (being the rate of interest at which
pension liabilities could effectively be settled) which reflects current market
rates.
 
    Including members' contributions, the pension expense for the UK defined
benefits plan in accordance with US GAAP on this basis is as follows:

    The effect of applying US GAAP in the calculation of the UK pension expense
compared with the results in accordance with UK GAAP is Nil in 1993, a reduction
in 1994 of B.P.195,000 and a charge of B.P.286,000 in 1995. These amounts were
not considered sufficiently material to record as a significant difference
between UK GAAP and US GAAP in note 28.

25. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    Statement of Financial Accounting Standards No. 107 requires disclosure of
the estimated fair values of financial instruments for which it is practicable
to estimate the value.
 
    With regard to cash and cash equivalents, loans, short term debt, non-trade
accounts receivables and payables and long term bank debt, terms of these
financial instruments are similar to those available in the current market.
Accordingly, carrying values approximate fair values.
 
    The fair value of the Group's long term unlisted investments in related
companies and other investments has been reviewed and the Directors consider
that in total these investments are stated at their approximate fair value based
on this review.
 
    The fair value of the Group's 9.5% Convertible Capital Bonds is based on the
quoted market prices for these bonds at November 30. At November 30, 1995, 1994
and 1993 the restated carrying amount of these bonds was B.P.43.8 million,
B.P.43.7 million and B.P.43.6 million and their fair value was B.P.32.1 million,
B.P.32.3 million and B.P.43.9 million respectively. As mentioned in note 14 the
Group does not use derivative financial instruments to manage its foreign
currency or interest rate risks.

    The Group's statement of cash flows is prepared in accordance with UK
Financial Reporting Standard (FRS1), the objectives and principles of which are
substantially consistent with Statement of Financial Accounting Standards No.
95, "Statement of Cash Flows" ("SFAS95"), under US GAAP, and International
Accounting Standard 7 ("IAS 7") . The principal differences between the
standards relate to classification.
 
    Cash flows from taxation and returns from investments and servicing of
finance under FRS1 would be included as operating activities under SFAS95. Under
FRS1, net cash and cash equivalents comprise cash, investments and short-term
deposits which were within 3 months of maturity when acquired and short-term
borrowings repayable within 3 months from the date of their advance. Under
SFAS95, short-term borrowings repayable and overdraft balances would not be
included in cash and cash equivalents, and only investments and short-term
deposits with an original maturity of 3 months or less are included in cash and
cash equivalents.

    Fair value adjustments relate to intangibles eliminated in line with Group
accounting policies, the estimated value of property and equipment, allowances
for obsolete inventories and doubtful accounts receivable, provisions for
maintenance and reorganization costs of businesses acquired. Adjustments in
respect of prior year's acquisitions relate in 1994 to the estimated value of
assets and liabilities in Telecom Security Limited and in 1993 principally to
the estimated value of property and equipment in Sonitrol Management Corporation
in the United States. Apart from the consideration shown above, the acquisitions
had no material effect on the Group's cash flows.

28. SIGNIFICANT DIFFERENCES BETWEEN UK GAAP AND US GAAP
 
    The consolidated financial statements of the Group are prepared in
conformity with UK generally accepted accounting principles (UK GAAP) which
differs in certain significant respects from US GAAP. Differences which have a
significant effect on consolidated net income or shareholders' equity are
discussed below. While this is not a comprehensive summary of all differences
between UK GAAP and US GAAP, other differences are not likely to have a
significant effect on the consolidated net income or shareholders' equity of the
Group.
 
  Intangible assets
 
    US GAAP requires that intangible assets are amortized over their estimated
useful life which may not exceed 40 years. Under UK GAAP the cost of goodwill,
and other intangible assets, which are considered to be similar in nature to
goodwill, may be written off directly to reserves in the year in which the
assets are acquired. In the tables below the intangible assets which are
substantially comprised of goodwill, subscriber contracts and customer lists,
and franchise contracts are amortized over estimated useful lives which range
from 15 to 40 years. The average useful life of each class of asset is estimated
to be 15 years for subscriber contracts, 30 years for customer lists and 40
years for franchise contracts.

28. SIGNIFICANT DIFFERENCES BETWEEN UK GAAP AND US GAAP--(CONTINUED)
 
  Deferred income taxes
 
    Under UK GAAP, deferred taxation is provided on the liability method for all
timing differences except where the directors consider that no liability will
arise in the foreseeable future. Following the issuance of Statement of
Financial Accounting Standards No. 109: "Accounting for Income Taxes", US GAAP
provides for the use of the liability method but requires that provisions be
made for all temporary differences. The tables below incorporate adjustments to
shareholders' equity and net income to reflect full provision for deferred
taxation on all temporary differences under the liability method. Temporary
differences arise mainly from the difference between the tax basis of property
and equipment and intangible assets and their corresponding carrying amounts in
the financial statements.
 
  Pensions
 
    Since 1989, as permitted under UK GAAP, the accounting policy of the Group
has been to account for pension costs on a long-term basis spreading the
expected pension costs over the service lives of employees, using assumptions as
advised by an actuary. Under US GAAP, the calculations need to be made using
market rates of interest which were higher than the long-term assumptions made
by the actuary.
 
    A further difference is that under UK GAAP a cost variation is calculated by
spreading the surplus (the difference between the actuarial value of the assets
and the liabilities) over the service lives of the employees, whereas US GAAP
calculates this variation in a particular way--as the expected investment return
on the assets at market value, plus amortization of the surplus (the difference
between the market value of the assets and the actuarial value of the
liabilities), less interest at the market rate on the actuarial value of the
liabilities.
 
  Related companies
 
    In the tables below, estimated adjustments have been made in respect of
related companies accounted for by the Group under the equity method, where such
related companies adopt accounting policies which conform with UK GAAP which
differ significantly from those required under US GAAP. These adjustments relate
primarily to the accounting treatment for goodwill and intangible assets (see
discussion above on intangible assets).
 
  Sale of subsidiary and related companies
 
    Under UK GAAP goodwill on acquisition of subsidiaries and related companies
is written off to reserves. On sale of these companies the goodwill previously
written off is recharged in full to the profit and loss account. Under US GAAP
the goodwill on acquisition is carried in the balance sheet and amortized over
its estimated useful life. On sale of these companies the profit on sale is
therefore higher under US GAAP by the amount of the amortization previously
charged to income.
 
  Discontinued activities
 
    The results of discontinued activities are separated on the profit and loss
account under both UK accounting practice and US GAAP. Under UK GAAP a
discontinued operation refers to an operation that was material and whose sale
or termination has a material effect on the nature and focus of the operations
and represents a material reduction in its operating facilities. Under US GAAP,
only the closure, sale or disposal of a separately identifiable segment of a
business qualifies as a discontinued activity.

  Redeemable Preference Shares
 
    The 5% and 6% Convertible Cumulative Redeemable Preference Shares (the
"Preference Shares") of Automated Security (Holdings) PLC are convertible into
Ordinary Shares, at the option of the holder, in the month of May in each of the
years 1987 to 1999 (for the 5% Preference Shares) and on May 31 in each of the
years 1991 to 2006 ( for the 6% Preference Shares). Automated Security
(Holdings) PLC has the option between May 31, 2000 and May 31, 2005 (for the 5%
Preference Shares) and June 1, 2006 to May 31, 2009 (for the 6% Preference
Shares) to redeem the Preference Shares at par and in any event must redeem on
May 31, 2005 (for the 5% Preference Shares) or May 31, 2009 (for the 6%
Preference Shares). Under UK GAAP the Preference Shares form part of
shareholders' equity whereas under US GAAP they are classified as a separate
non-current liability. Accordingly, for the purposes of the reconciliation the
total amount of the Preference Shares has been excluded from shareholders'
equity and the dividends on the Preference Shares have been deducted to compute
net income attributable to Ordinary Shareholders.
 
  Earnings per share
 
    The earnings per share calculation under UK GAAP is set out in the
accounting policies. Under US GAAP, primary earnings per Ordinary Share is
calculated by dividing the profit attributable to ordinary shareholders by the
weighted average number of shares in issue during the year. The weighted average
number of shares includes common stock equivalents including all convertible
preference shares and convertible unsecured loan stock calculated under the "If
Converted Method" and share options using the "Treasury Stock Method". The
profit attributable to ordinary shareholders comprises the estimated net income
in accordance with US GAAP and the dividends and interest (net of tax) of
preference shares and loan stock which have been included in calculating the
common stock equivalents. Fully diluted earnings per share have not been
presented as they do not vary significantly from primary earnings per share.
 
  Pre-acquisition tax losses
 
    Under UK GAAP contingent tax assets on acquired businesses are recognized at
the date of acquisition only to the extent that their recoverability can be
foreseen with reasonable certainty. Any subsequent benefits which arise are
recognized as a reduction in the tax charge. Under US GAAP such benefits are
treated as a retrospective reduction of the goodwill arising on the acquisition.
 
  Employees' share ownership plan
 
    Automated Security (Holdings) PLC has advanced funds to the Automated
Security (Holdings) PLC Employees' Share Ownership Plan Trust ("ESOP"). Under UK
GAAP following the introduction of UITF Abstract 13 the net balance due from the
ESOP has been shown in investments for both 1994 and 1995; previously these
balances were shown in long term accounts and notes receivable. Under US GAAP
these receivables are shown as a deduction from shareholders' equity.
 
  Recently Issued Accounting Pronouncements
 
    (i) In March 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 121, Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed Of ("SFAS 121"). SFAS
121 provides guidance on when to assess and how to measure impairment of
long-lived assets, certain identifiable intangibles and goodwill related to
those assets to be held and used and for long-lived assets and certain
identifiables to be disposed of. This

Statement is effective for financial statements for fiscal years beginning after
December 15, 1995. The Company has not yet assessed the future impact of
adopting SFAS 121.
 
    (ii) In October 1995 the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based
Compensation ("SFAS 123"). SFAS 123 establishes accounting and disclosure
standards for stock-based employee compensation arrangements. The Statements is
effective for fiscal years beginning after December 15, 1995. The Company has
decided that, upon implementation of SFAS 123, it will continue to account for
stock-based compensation arrangements in accordance with the accounting method
prescribed by APB Opinion No. 25, which is an alternative allowed under SFAS
123.
 
    The following is a summary of the adjustments (gross of tax) to net income
and shareholders' equity which would have been required if the Group had applied
US GAAP instead of UK GAAP.

            Drawdown Date or such shorter period as the Agent may allow PROVIDED
            THAT no Drawdown Notice maybe served in respect of an Advance and no
            Advance will be made:

            (a)   unless the Conditions Precedent shall have been satisfied; or

            (b)   if a Default or Default Occurrence has occurred and is
                  continuing or if a Default would occur on the making of such

            (c)   unless the representations and warranties deemed to be
                  repeated pursuant to Clause 13.3 on the relative Drawdown Date
                  are, or will be, true and accurate on the date on which the
                  relative Drawdown Notice is served and on the relative
                  Drawdown Date; or

            (d)   in respect of a Revolving Advance, if the making of such
                  Revolving Advance would cause the aggregate Original Sterling
                  Amount of all Revolving Advances to be greater than the
                  Revolving Facility Limit.

            5.3.2 Subject always to the other terms of this Agreement, a
                  Drawdown Notice shall be irrevocable and the Company shall be

      which its unutilised Term Loan Commitment or Revolving Loan Commitment, as
      the case may be, bears to the unutilised part of the Total Term Loan
      Commitments or the Total Revolving Loan Commitments, as the case may be,
      on the relative Drawdown Date.

5.4.2 Subject to Clause 5.6, each Bank shall on the relative Drawdown Date

      requested in the relative Drawdown Notice.

      Facility Limit (together the "First Advances"). On the Refinancing Date,
      the Existing Advances shall be deemed to be refinanced with the proceeds
      of the First Advances by the Banks on the basis that each Bank refinances
      that part of the Existing Advances owed to such Bank and that the Interest
      Periods relating to such Bank's Participation in the First Advances have
      Interest Dates which are the same as those parts of the Existing Advances
      which it refinances.

5.6.3 In respect of any part of the First Advances with an Interest Date of 3rd
      or 4th April 1996, on such date, that part shall be deemed to be
      refinanced with a Participation of the relevant Banks in an Advance with a
      Interest Period expiring on 9th April 1996.

5.6.4 In respect of any part (the "Short Term Part") of the First Advances with
      a corresponding Interest Date of 15th January 1996, on such date, the
      Short Term Part shall be deemed to be refinanced with a Participation of
      the relevant Banks in an Advance with an Interest Period expiring on 31st
      March 1996. On 31st March 1996 the Short Term Part, to the extent not
      applied in repayment and permanent reduction, of the Facilities shall be
      deemed to be refinanced with a Participation of the relevant Banks in an
      Advance with an Interest Period expiring on 30th June 1996.

5.6.5 The provisions of Clauses 5.6.2, 5.6.3 and 5.6.4 shall have automatic
      effect and shall not require the service of any Drawdown Notice by the
      Company.

5.6.6 On and from 9th April 1996 all Advances, other than those forming all or
      part of the Short Term Part, shall be made and funded in accordance with
      the other terms of this Agreement.


<PAGE>

5.6.7 If, prior to 30th June 1996, the Agent serves notice under Clause 15.1,
      the Banks shall promptly make such payments amongst themselves in order to
      make their Participations in Advances what they would have been but for
      Clauses 5.6.2 to 5.6.6 inclusive on the basis of the then current exchange
      rates.

5.6.8 Prior to 30th June 1996, all prepayments of the Loans shall be applied as
      they would have been if the relevant prepayment was made after 30th June
      1996.

5.6.9 Interest on the First Advances (other than the Short Term Part) at the
      rate currently applicable to the Existing Advances shall be paid on 5th
      January 1996 and on the Interest Dates relating thereto and shall be
      deemed to have accrued from the date on which the interest periods current
      at the date hereof for the Existing Advances commenced.

5.6.10 Any commitment commission accrued but unpaid on undrawn amounts under the
      Existing Facilities shall be paid by the Company on the date or dates it
      would have been payable pursuant to the terms of the Existing Facilities.

5.6.11 Each of the Banks hereby authorise, and instruct the Facility Agent, to
      transfer on the Refinancing Date, to the credit of any current account of
      the Company which forms part of the Overdraft Facility, any monies
      standing to the credit of a suspense account held with the Facility Agent
      in connection with the Existing Facilities.


6.    THE OVERDRAFT FACILITY AND THE UNCOMMITTED ENGAGEMENTS FACILITY

6.1   Nature of Overdraft Facility

6.1.1 The Overdraft Facility is made available to the Borrowers in accordance
      with this Clause 6 and the General Terms.

6.1.2 No utilisation of the Overdraft Facility may be made prior to the
      Refinancing Date and on the Refinancing Date all amounts outstanding under
      the overdraft facilities forming part of the Existing Facilities shall be
      deemed to have been made available under the Overdraft Facility and shall
      automatically be treated thereafter as outstanding under the Overdraft
      Facility.

6.1.3 A Borrower wishing to utilise the Overdraft Facility shall complete such
      mandate and other documents as the relevant Bank shall reasonably require.

6.1.4 The Overdraft Facility shall cease to be available on the Final Repayment
      Date or such earlier date on which it is cancelled or terminated in
      accordance with the terms hereof.

6.2   Utilisation or Overdraft Facility

6.2.1 Subject to the other terms of this Agreement, each Bank, to the extent of
      its Overdraft Commitment, agrees to make the Overdraft Facility available
      on a


<PAGE>

      revolving basis to the Borrowers to be utilised on any Business Day by way
      of overdraft on usual banking terms PROVIDED THAT, subject to Clause
      6.2.2, no demand for repayment shall be made in respect thereof other than
      in accordance with Clause 15.2.

6.2.2 Notwithstanding Clause 6.2.1, as and from any date on which the Overdraft
      Outstandings exceed the Overdraft Facility Limit all amounts outstanding
      under the Overdraft Facility shall automatically become repayable on
      demand made by the Bank which makes available the relevant overdraft under
      the Overdraft Facility.

6.2.3 No utilisation of the Overdraft Facility under Clause 6.2.1 shall be made
      if it would result in the amounts outstanding by way of overdraft under
      the Overdraft Outstandings exceeding the Overdraft Facility Limit.

6.2.4 For the avoidance of doubt, a Bank may, without liability, return cheques
      unpaid and reflise to honour direct debits, Bankers Automated Clearing
      System facilities, standing orders and any other payment orders if the
      payment of such items would result in a breach of Clause 6.2.3.

6.3   Utilisation or the Uncommitted Engagements Facility

6.3.1 The Uncommitted Engagements Facility is uncommitted and the Working
      Capital Bank shall not be obliged to issue, or enter into, any Engagement.

6.3.2 The Engagements Facility shall be available on normal banking terms
      applicable to engagements and be subject to the General Terms.

6.3.4 An Engagement will only be issued or entered into on a Business Day.

6.3.5 Each Borrower hereby unconditionally and irrevocably agrees and undertakes
      to the Working Capital Bank as follows.

            Working Capital Bank indemnified from and against all actions,
            suits, proceedings, claims, demands, liabilities, damages, costs,
            expenses, losses and charges whatsoever in relation to or arising
            out of any Engagement entered into, or issued, at the request of
            such Borrower and such Borrower will pay the Working Capital Bank on
            demand the amount of all payments made (whether directly or by way
            of set-off, counterclaim or otherwise howsoever) and all losses,
            costs and expenses suffered or incurred from time to time by the
            Working Capital Bank under or by reason or in consequence of any
            such Engagement and any of the aforesaid indemnities relating
            thereto;

      (b)   save in the case of negligence, fraud or willful default on the part
            of the Working Capital Bank:


<PAGE>

            (i)   the Working Capital Bank is hereby irrevocably authorised by
                  each Borrower to comply with the terms of any demand served or
                  purporting to be served on the Working Capital Bank pursuant
                  to any Engagement without any reference to, or lurther
                  authority from, any Borrower and without any enquiry by the
                  Working Capital Bank into the justificationfor such. demand or
                  the validity thereof; and


            (ii)  each Borrower further agrees that any payment which the
                  Working Capital Bank shall make in accordance or purporting to
                  be in accordance with such a demand shall be binding on each
                  Borrower and be accepted by such Borrower as conclusive and
                  binding evidence that the Working Capital Bank was liable to
                  comply with the terms of such demand and was liable to do so
                  in the manner and for the amount in which the Working Capital
                  Bank effected such compliance;

      (c)   save as specifically provided in Clause 6.3.5(b) the liability of
            each Borrower under this Clause 6.3.5 shall not be discharged,
            lessened or impaired by any time being given or by any thing being
            done or other circumstance whatsoever which, but for this provision,
            would or might operate to exonerate or discharge such Borrower; and

      (d)   the indemnity contained in this Clause 6.3.5 shall constitute and be
            a continuing security to the Working Capital Bank and the said
            indemnity shall extend to each Engagement as it may, from time to
            time, be varied, modified, amended or extended.

6.3.6 Each Borrower hereby agrees that it shall pay to the Working Capital Bank
      interest on the amount of each payment, loss, cost and expense made,
      suffered or incurred from time to time by the Working Capital Bank under
      or by reason or in consequence of any Engagement entered into or issued at
      the request of such Borrower and any of the indemnities contained in
      Clause 6.3.5 from and including the date upon which such payment, loss,
      cost or expense is made, suffered or incurred as aforesaid up to and
      including the date upon which payment or reimbursement of such amount is
      demanded from such Borrower. The amount of such interest shall be
      calculated in accordance with the provisions of Clause 8.3. For the
      avoidance of doubt, interest on sums demanded under the provisions of
      Clause 6.3.5 shall also accrue in accordance with Clause 8.3.

7.    AVAILABILITY OF ALTERNATIVE CURRENCIES

7.1   Non-Availability

      If, before 10.00 a.m. (London time) on the second Business Day prior to

      Bank that:


<PAGE>

      (i)   it is reasonably unable to obtain sufficient funds necessary to
            find its Participation in such Advance in the ordinary course of
            business in the London Inter-Bank Market; or

      (ii)  central bank or other governmental authorisation in the country of
            the proposed Alternative Currency is required to permit its use by
            such Bank for the making of such Advance and the authorisation has
            not been obtained or is not in full force and effect; or

      (iii) the use of the proposed Alternative Currency is restricted or
            prohibited by any request, directive, regulation or guideline of any
            governmental body, agency, department or regulatory or other
            authority (whether or not having the force of law) in accordance
            with which such Bank is accustomed to act;

      the Agent shall give notice to the Company to that effect before 10.30
      a.m.(London time) on the second Business Day prior to such Drawdown Date.

7.2   Effect of Notice

      not be made in which event, such Advance will not be made.

7.2.2 If the Company does not elect as set out in Clause 7.2.1, the relevant
      Advance shall be denominated in Sterling and, in respect of such Advance,
      there shall be substituted in the definition of "LIBOR" contained in

      months) as the Banks may agree with the Company.

8.2.2 The Company shall, subject to Clause 8.2.6, in each Drawdown Notice select
      the Interest Period of the Advance to which such Drawdown Notice relates.

8.2.3 In respect of Term Advances, interest shall be calculated by reference to
      successive Interest Periods. Each succeeding Interest Period relative to a
      Term Advance shall commence on the last day of the preceding Interest
      Period for such Advance. The Borrower shall at least three (3) Business

      Term Advance notify the Agent in writing of the next Interest Period
      applicable to such Advance.

      Date and if an Interest Period selected purports so to do, it shall
      nevertheless expire on the Final Repayment Date.

8.2.7 If the Company fails to select an Interest Period for an Advance, the
      Company shall, subject to Clause 8.2.6, be deemed to have selected an
      Interest Period of 3 months.

8.2.8 Any Interest Period which commences on the last Business Day in a month or
      on a Business Day for which there is no numerically corresponding day in
      the month in which that Interest Period is to end, shall (subject to
      Clause 8.2.6) end on the last Business Day in that later month.

      Business Day shall end on the next succeeding Business Day or, if that day
      falls in the following month, on the immediately preceding Business Day.

8.3   Default Interest

8.3.1 If a Borrower fails to pay any sum payable under any Financing Document on
      its due date, a Borrower shall pay default interest on such sum (or, as
      the case may be, the amount thereof for the time being due and unpaid) to
      the Agent for the account of the Agent and the Banks or the Working
      Capital Bank, as the case may be, from the due date to the date of actual
      payment in full calculated by reference to successive Interest Periods
      (each of such duration as the Agent may from time to time select


<PAGE>

      and the first beginning on the relative due date) at the rate per annum
      being the aggregate of:

      (i)   1 per cent. per annum;

      (ii)  the Margin from time to time;

      (iii) LIBOR; and

      (iv)  in the case of sums denominated in Sterling, the Mandatory Liquid
            Asset Costs.

      8.3.2 So long as the default continues, such rate shall be recalculated in
            accordance with the provisions of this Clause 8.3 on the last day of
            each such Interest Period and unpaid interest then payable but
            unpaid under this Clause shall be compounded at the end of each
            Interest Period.

      8.4   Interest under the Overdraft Facility

      8.4.1 Interest on all amounts outstanding by way of overdraft under the
            Overdraft Facility shall accrue at the rate per annum which is the
            aggregate of:

            (i)   the Margin from time to time; and

            (ii)  the most recently published base rate of the Bank making
                  available the relevant overdraft.

      8.4.2 Interest under Clause 8.4.1 on amounts outstanding by way of
            overdraft shall be paid by the relevant Borrower to the Bank making
            available the relevant overdraft on such Bank's usual quarterly
            charging days and (if not such a quarterly charging day) the Final
            Repayment Date.

      8.4.3 Each Bank making available an overdraft under the Overdraft Facility
            is hereby authorised by each Borrower to debit all interest payable
            by such Borrower under this Clause 8.4 to the current account held
            by such Borrower with such Bank and such Bank shall notify such
            Borrower of the amount debited in accordance with the normal
            practice of such Bank.

      8.5   Engagements Commission

            Commission in respect of each Engagement entered into or issued
            under the Uncommitted Engagements Facility shall:

            (i)   accrue from day to day on the Engagement Amount of such
                  Engagement at a rate per annum equal to the higher of:

                  (a)   the Margin from time to time; and


<PAGE>

                  (b)   the Working Capital Bank's standard charges for the
                        relevant Engagement;

            (ii)  be calculated on the basis of actual days elapsed and a 360
                  days' year in the case of an Engagement denominated in a
                  currency other than Sterling, but if such Engagement is
                  denominated in Sterling, a 365 days' year; and

            (iii) be paid in Sterling on the Working Capital Bank's normal
                  charging days for the relevant Engagement.

8.6   Calculation and Payment of Interest

8.6.1 Promptly following the beginning of each Interest Period and, in the
      circumstances of the Margin reducing, on the date on which such reduction
      becomes effective, the Agent will notify the relevant Borrower of the rate
      and amount of interest payable for such Interest Period (but in the case
      of such interest calculated under Clause 8.3, any such notification need
      not be made more frequently than weekly). Such notification shall set out
      in reasonable detail the basis of computation of the amount of interest so
      payable.

8.6.2 Interest due from a Borrower to any of the Agent, the Working Capital Bank
      and the Banks under this Agreement shall:

      (i)   accrue from day to day at the appropriate rate calculated under this
            Clause 8;

      (ii)  except as otherwise provided in this Agreement (and, in particular,
            Clauses 8.4 and 8.6.3), be paid by the relevant Borrower to the
            Agent for the account of the Banks or the Agent, as the case may be,
            in arrear on each Interest Date, save that in the case of any
            Interest Period which is for longer than 6 months, such Borrower
            shall pay interest 6 monthly in arrear and on the relative Interest
            Date;

      (iii) be calculated on the basis of the actual number of days elapsed and,
            in the case of Sterling, a 365 day year or, in the case of an
            Alternative Currency, a 360 day year or, if different, such number
            of days as is market practice for the relevant currency; and

      (iv)  be payable after as well as before judgment.

8.6.3 The Additional Margin, if any, shall be payable on 30th June 1996 to the
      Banks, pro rata to their Commitments.

8.7   Market Disruption

      If:

      (i)   no relevant rate appears on the Reuter Monitor Money Rates Service
            for the purposes of paragraph (a) in the definition of LIBOR and the
            Agent

<PAGE>

            determines that at or about 11.00 a.m.(London time), in the case of
            Sterling, or, in the case of an Alternative Currency, 2 Business
            Days before, the first day of an Interest Period none of the
            Reference Banks is offering to leading banks in the London
            Inter-Bank Market deposits in Sterling or an Alternative Currency,
            as appropriate, for the required period; or

      (ii)  no relevant rate appears on the Reuter Monitor Money Rates Service
            for the purposes of paragraph (a) in the definition of LIBOR and
            before the close of business in London in the case of an Alternative
            Currency, 2 Business Days before, or in the case of Sterling, on the
            first day of an Interest Period the Agent has been notified by each
            of a group of Banks the aggregate of whose Commitments, as the case
            may be, is equal to at least 33 per cent. of the Term Loan
            Commitments or the Revolving Loan Commitments, as the case may be,
            that the rate at which such deposits are being so offered does not
            accurately reflect the cost to it of obtaining such deposits; or

      (iii) by reasons of circumstances generally affecting the London
            Inter-Bank Market, reasonable and adequate means do not exist for
            ascertaining LIBOR for any Advance for any relative Interest Period;

      then:

      (a)   the Agent shall promptly give notice to the Company in writing of
            such event (a "market disruption notice");

      (b)   the Agent and the Company shall discuss an alternative basis for
            calculating the relative rate of interest for the relative Advance
            (the "Affected Advance") on the basis that the net return to the
            Banks shall be no less than it would have been had such event not
            occurred ("alternative basis");

      (c)   the Company shall either:

            (i)   in the case of (i) or (iii) above, immediately withdraw the
                  Drawdown Notice relating to the Affected Advance or, in any
                  case, throughout any period in relation to which a market
                  disruption notice is in effect (subject always to Clause
                  8.7(d)) pay interest to the Agent for the account of each of
                  the Banks on each Bank's Participation in the Affected Advance
                  at the rate per annum determined by the Agent to be the
                  aggregate of:

                  (1)   the Margin during such period;

                  (2)   the rate notified by each Bank to the Agent to be the
                        rate which expresses as a percentage rate per annum the
                        cost to such Bank of funding from whatever


<PAGE>

                        sources it may reasonably select its Participation in
                        the Affected Advance; and

                  (3)   where the Affected Advance is denominated in Sterling,
                        Mandatory Liquid Asset Costs; or

            (ii)  if it has not promptly withdrawn the Drawdown Notice relating
                  to the Affected Advance, at any time that a market disruption
                  notice is in force and an alternative basis has not been
                  agreed upon giving the Agent 10 days' prior written notice,
                  prepay the Affected Advance, together with interest accrued

                  any other governmental, monetary or other authority (whether
                  in the United Kingdom or elsewhere) having jurisdiction over
                  the relative Bank; or

      (b)   any change in the interpretation or application thereof,

      shall:

            (i)   subject any Bank to any Tax Liability in connection with its
                  Commitment or Participation in the Facilities or any part
                  thereof or in connection with any of the Financing Documents

            (ii)  change the basis or timing of Taxation of any Bank in respect
                  of payments of principal, interest or any other amount paid,
                  payable or to become payable in connection with its Commitment
                  or Participation in the Facilities or in connection with any
                  of the Financing Documents (or the treatment for Taxation
                  purposes of such payments); or

            (iii) change the basis or timing of the treatment of any of the
                  Banks for Taxation purposes in respect of any principal,
                  interest or other amounts paid, payable or to become payable
                  by such Bank on, or otherwise in respect of, deposits or loans

                  resources to its obligations under or in relation to the
                  Facilities so that it is unable to obtain the rate of return
                  on its overall capital which it would have been able to obtain
                  but for any of its entering into, performing its obligations
                  and assuming or maintaining its Commitment or its
                  Participation in the Facilities;


<PAGE>

                  and the result of any of the foregoing is either to increase
                  the cost to any of the Banks of making available its
                  Commitment or its Participation in the Facilities or any part
                  thereof or of carrying out any of the transactions provided
                  for or contemplated by any of the Financing Documents or to
                  reduce the amount of any payment received or receivable by
                  such Bank or to reduce its return from the Facilities, then
                  and in any such case:

                  (aa)  such Bank shall notify the Company and the Agent;

                  (bb)  the Company shall pay (as additional interest) from time
                        to time to such Bank for the account of such Bank within
                        5 Business Days of demand all amounts which such Bank
                        certifies (in a certificate which shall set out in
                        reasonable detail so far as is practicable the basis of
                        the computation of such amounts) to be necessary to
                        compensate such Bank for the additional cost or
                        reduction;

                  (cc)  without prejudice to the foregoing, each Bank confirms
                        that if it notifies the Company and the relative
                        Borrower as aforesaid such Bank shall take such steps as
                        such Bank considers reasonable to reduce or avoid the
                        additional cost or reduction including the transfer of
                        its Lending Office to another jurisdiction or the
                        transfer of its rights and obligations to another
                        financial institution and, if the Company so requests,
                        such Bank shall consult with the Company and the Agent
                        with a view to finding a means of reducing or avoiding
                        the additional cost or reduction PROVIDED THAT neither
                        such Bank nor the Agent shall be obliged to continue
                        such negotiations for a period of longer than 30 days;
                        and

                  (dd)  without prejudice to the Company's obligation to pay to
                        the relative Bank the due amount under this Clause 11.2,
                        the relative Borrower, may, at any time alter receipt of
                        such notification, so long as the circumstances giving
                        rise to such additional cost or, as the case may be,
                        reduction are continuing, on giving not less than 10

                        interest thereon (subject always to the provisions of
                        Clause 12.3). In such event, such Bank's Commitment
                        shall be reduced to zero.

      (a)   ensure or procure that the deduction or withholding is made and that
            it does not exceed the minimum legal requirement therefor;

      (b)   pay, or procure the payment of, the full amount deducted or
            withheld to the relevant Taxation or other authority in accordance
            with the applicable law;

      (c)   increase the payment in respect of which the deduction or
            withholding is required so that the net amount received by the
            relative payee after the deduction or withholding (and after taking
            account of any further deduction or withholding which is required
            to be made as a consequence of the increase) shall be equal to the
            amount which the relative payee


<PAGE>

            would have been entitled to receive in the absence of any
            requirement to make any deductions or withholdings; and

      (d)   promptly deliver or procure the delivery to the relative payee of
            receipts evidencing each of the deductions or withholdings which has
            been made.

12.4.3 If the Agent is obliged to make any deduction or withholding from any
      payment to any of the Banks (an "agency payment") which represents an
      amount or amounts received by the Agent from any Borrower under any of the
      Financing Documents, the Company shall pay directly to the relative Bank
      such sum (an "agency compensating sum") as will, after taking into account
      any deduction or withholding which the Company is obliged to make from the
      agency compensating sum, enable such Bank to receive, on the due date for
      payment of the agency payment, an amount equal to the agency payment which
      such Bank would have received in the absence of any obligation to make any
      deductions or withholdings.

12.4.4 A Borrower shall not be required to pay an additional amount under this
      Clause 12.4 if the relevant Bank either:

      (a)   is not at the date hereof a Qualifying Bank; or

      (b)   ceases after the date hereof to be a Qualifyng Bank otherwise than
            as a consequence of a change in any applicable law, regulation,
            practice, concession, regulatory requirement or request (whether or
            not having the force of law) of the Bank of England, the European
            Community or of any other governmental, monetary or other authority;

      and, in either case, the obligation to deduct or withhold would not have
      arisen if the relevant Bank had been a Qualifying Bank.

12.4.5(a)   If any of the Banks determines, in its absolute discretion, that it
            has received, realised, utilised and retained a Tax benefit by
            reason of any deduction or withholding in respect of which a
            Borrower has made an increased payment or paid an agency
            compensating sum under this Clause 12.4, such Bank shall, provided
            that the Agent and each Bank has received all amounts which are then
            due and payable by the obligors under any of the Financing
            Documents, pay to such Borrower (to the extent that such Bank can do
            so without prejudicing the amount of such benefit or repayment and
            the right of such Bank, to obtain any other benefit, relief or
            allowance which may be available to it) such amount, if any, as such
            Bank, in its absolute discretion shall determine, will leave such
            Bank in no worse position than it would have been in if the
            deduction or withholding had not been required PROVIDED THAT:

            (i)   each Bank shall have an absolute discretion as to the time at
                  which and the order and manner in which it realises or
                  utilises any Tax benefit and shall not be obliged to arrange
                  its business or its Tax affairs in any particular way in order
                  to be eligible for any credit or refund or similar benefit;


<PAGE>

            (ii)  no Bank shall be obliged to disclose any information regarding
                  its business, Tax affairs or Tax computations; and

            (iii) if a Bank has made a payment to a Borrower pursuant to this
                  Clause 12.4.5 on account of any Tax benefit and it
                  subsequently transpires that such Bank did not receive that
                  Tax benefit, or received a lesser Tax benefit, such Borrower
                  shall, on demand, pay to such Bank such sum as the relative
                  Bank may determine as being necessary to restore its after-Tax
                  position to that which it would have been had no adjustment
                  under this Clause (iii) been necessary. Any sums payable by a
                  Borrower to a Bank under this Clause (iii) shall be subject to
                  the provisions of Clause 18.8.

      (b)   No Bank shall be obliged to make any payment under this Clause
            12.4.5 if, by doing so, it would contravene the terms of any
            applicable law or any notice, direction or requirement of any
            governmental or regulatory authority (whether or not having the
            force of law).

12.5  Mitigation

      If, in respect of any Bank or the Working Capital Bank, circumstances
      arise which would, or would upon the giving of notice, result in an
      increase in the amount of any payment to be made to it or for its account
      pursuant to Clause 12.4 (Grossing up), then, without in any way limiting,
      reducing or otherwise qualifying the rights of such Bank or the Working
      Capital Bank, as the case may be, or the obligations of each Borrower
      under Clause 12.4 such Bank or the Working Capital Bank, as the case may
      be, shall promptly upon becoming aware of the same notify the Agent
      thereof and, in consultation with the Agent and the Company and to the
      extent that it can do so without prejudice to its own position, take
      reasonable steps to mitigate the effects of such circumstances including
      the transfer of its Lending Office.

12.6  Prepayment Right

      If the Company is required to make an increased payment for the account of
      a Bank under Clause 12.4.2 or 12.4.3 (but only so long as such requirement
      exists), subject to giving the Agent and such Bank not less than 10 days'
      prior written notice (which shall be irrevocable), the Company may prepay
      such Bank's Participation in the Advances together with accrued interest
      thereon PROVIDED THAT any such prepayment shall be subject to the
      provisions of Clause 12.3. In such circumstances, the Commitment of the
      relevant Bank will be reduced to zero.

12.7  Accounts

      Each Bank shall maintain in accordance with its usual practice an account
      or accounts, which account or accounts shall, in the absence of manifest
      error, as between the Borrowers and such Bank be conclusive evidence of
      the amounts from

      payment.

12.8.2 If a Borrower does not in fact make such payment to the Agent, each Bank
      shall forthwith on demand by the Agent repay to the Agent the amount made
      available to such Bank (together with interest thereon at the rate
      determined by the Agent as being its cost of funding such payment).

12.9  Banks' Payments

12.9.1 The Agent may assume that each Bank has made its Participation in an
      Advance available to the Agent on the relative Drawdown Date and the Agent
      may in reliance upon such assumption, make available to the Company a
      corresponding amount.

12.9.2 If such corresponding amount is not in fact made available to the Agent
      by such Bank, the Agent shall be entitled to recover such corresponding
      amount (together with interest thereon at the rate determined by the Agent
      as being its cost of funds in the circumstances) on demand from the
      Company.

12.9.3 Where the Agent has made available an amount to the Company in reliance
      upon the assumption contained in Clause 12.9.1 but a Bank has not made its
      Participation in the relevant Advance available to the Agent then, unless
      that Bank notified the Agent in writing prior to the relevant Drawdown
      Date that it would not be making its Participation in such Advance
      available, that Bank shall:

      (a)   if the Company does not refund the corresponding amount to the Agent
            within 3 Business Days, reimburse the Agent for such amount
            (together with interest thereon at the rate determined by the Agent
            as being its cost of funds in the circumstances) on demand; and

      (b)   indemnify the Agent from and against all losses, costs, charges and
            expenses which the Agent may incur or sustain by reason of that Bank
            not having made its Participation in the relevant Advance available.

12.10 Appropriation

      If a Borrower shall pay a sum in relation to the Facilities which is less
      than the total amount due and payable by it under this Agreement on the
      day on which such sum is paid such Borrower hereby waives any rights it
      may have to make any appropriation thereof as between any amounts so due
      and payable and the sum so paid shall be applied in or towards
      satisfaction of principal, interest, fees and other sums which are due or
      overdue for payment on that day in such order as the Majority Banks may


<PAGE>

      determine PROVIDED THAT each Bank shail receive its pro rata share of any
      such sum.

12.11 Currency of Account

      All payments to be made by the Company in respect of an Advance, whether
      of interest or principal, shall be made in the currency in which such
      Advance is denominated. All payments to be made under any indemnity or
      reimbursement provision of this Agreement relating to costs, losses and
      expenses shall be paid in the currency in which the relative costs, losses
      or expenses were incurred.

      (a)   require the Borrowers immediately to repay the Term Loan, the

            demand made by the Agent on the instructions of the Majority
            Creditors.

      Upon the service of any such notice by the Agent the Banks' obligations
      shall be terminated and each of the Banks' Commitments shall be cancelled
      and reduced to zero.

15.2.2 Forthwith upon the Agent serving notice under Clause 15.2.1, each
      Borrower shall in respect of each Engagement entered into or issues at its
      request:

      (i)   use its best endeavours to procure the release of the Working
            Capital Bank from, such Engagement; and

      (ii)  without prejudice to (i) above, pay to the credit of such account as
            the working Capital Bank issuing such Engagement shall stipulate an
            amount equal to the maximum actual and contingent liabilities of the
            Working Capital Bank under such Engagement and charge the same to
            the Working Capital Bank on such terms as the Working Capital Bank
            may stipulate.

16.   SET-OFF AND PRO RATA PAYMENTS

16.1  Set-Off

      Each Borrower hereby authorises each of the Agent, the Banks and the
      Working Capital Bank to apply any credit balance on any account of such
      Borrower with any of the Agent, the Banks and the Working Capital Bank in
      satisfaction of any sum due and payable from such Borrower pursuant to the
      terms of the Financial Documents. For this purpose each of the Agent, the
      Banks and the Working Capital Bank is authorised to purchase at its spot
      rate of exchange with the monies standing to the credit of any such
      account such other currencies as may be necessary to effect such
      application.

16.2  Pro Rata Sharing

16.2.1 If any Bank (the "Sharing Bank") shall at any time obtain (whether by way
      of voluntary or involuntary payment right of set-off, or otherwise) a
      proportion in


<PAGE>

      respect of its Participation in the Advances which is greater than the
      proportion obtained by the Bank or Banks respectively obtaining the
      smallest proportion of its Participation in the Advances, including a nil
      receipt, (the amount so obtained by the Sharing Bank which represents such
      excess being herein called "the excess amount")
      then:

      (i)   the Sharing Bank shall promptly pay to the Agent, for the account of
            the Banks, an amount equal to the excess amount, whereupon the Agent
            shall notify the Company of such amount and its receipt by the
            Agent;

      (ii)  the Agent shall treat such payment as if it were a payment by the
            Borrowers on account of sums owned to the Banks; and

      (iii) as between the Company and the Sharing Bank the excess amount shall
            be treated as not having been paid, while as between the Company and
            each Bank it shall be treated as having been paid to the extent any
            monies are received by such Bank.

      If, because of the liquidation of the Company, or for any other reason
      affecting the Company, the provisions of paragraph (iii) above cannot be
      given effect to as between the Banks on the one hand and the Company on
      the other hand then, as between the Banks, the Sharing Bank shall be
      treated as having purchased from each other Bank an amount of the
      Participations of that Bank in Advances which is equal to that part of the
      excess amount which is paid to that Bank and the Sharing Bank shall,
      accordingly, be entitled to receive all dividends and other payments
      received by that Bank in respect of such Participations, as the case may
      be, deemed to have been purchased by it.

16.2.2 Each Bank shall forthwith notify the Agent of any such receipt or
      recovery by it other than by payment through the Agent.

16.2.3 If any excess amount subsequently has to be wholly or partly refunded to
      the Company by any Sharing Bank which has paid an amount equal thereto the
      Agent under Clause 16.2.1, each Bank to which any part of that amount was
      distributed shall on request from the Sharing Bank repay to the Sharing
      Bank such Bank's pro rata share of the amount which has to be so refunded
      by the Sharing Bank. Each Bank shall on request supply to the Agent such
      information as the Agent may from time to time request for the purpose of
      this Clause 16.2. Notwithstanding the foregoing provisions of this Clause
      16.2, no Sharing Bank shall be obliged to share any excess amount which it
      receives or recovers pursuant to legal proceedings taken by it to recover
      any sums owing to it under this Agreement with any other party which has a
      legal right to, but does not, either join in such proceedings or commence
      and diligently pursue separate proceedings to enforce its rights in the
      same or another court, unless the proceedings instituted by the Sharing
      Bank are instituted by it without prior notice having been given to such
      party through the Agent and an opportunity to such party to join in such
      proceedings.

16.2.4 Nothing in this Agreement shall oblige the Agent or any Bank to apply any
      credit balance or other benefit received from the Borrower against the
      liabilities of the


<PAGE>

Borrower under this Agreement in priority to any other liabilities of the
Borrower to the Agent or that Bank.

17.1    Appointment and Duties

17.1.1  Each Bank hereby irrevocably appoints the Agent to act as its agent in

        purposes irrevocably authorizes and the Agent to take such action and to
        exercise and carry out all the discretions, authorities, rights, powers

        thereto.

        connection herewith or therewith in accordance with the instructions of
        the Majority Banks (but in the absence of any such instructions shall

        the Agent in accordance therewith shall be binding upon all the Banks.

17.1.3  The Agent may:

        (a)     act as agent or trustee or in a fiduciary or other capacity on
                behalf of any other group of banks or financial institutions
                providing facilities to any member of the Group or any
                associated company of a member of the Group or any associated
                company of a member of the Group without regard to the effect of
                exercising or omitting to exercise its discretions, authorities,
                rights, powers and duties in such capacity in the interests of
                the Banks and may act or omit to act in such capacity as freely

                agent for the Banks; and

        (b)     subscribe for, hold or be or become beneficially entitled to, or
                dispose of, shares of securities, or options or other rights to

                or any associated company of a member of the Group (and, in each
                case, may do so without liability to account).

17.1.4  For so long as Lloyds Bank Plc is the Agent, the Capital Markets Group
        of Lloyds Bank Plc shall be treated as a separate entity from any other
        of the divisions of the Agent or its Subsidiaries and, notwithstanding
        the generality of the foregoing, in the event that any of the Agent's
        divisions (including its Capital Market Group) or similar units or
        Subsidiaries should act for any member of the Group in any a capacity
        (whether as bankers or otherwise) in relation to any other matter, any
        information given by any member of the Group to such divisions, similar
        units or Subsidiaries



<PAGE>

        shall be treated as confidential and the Agent shall, as between itself
        and the Banks, not be obliged to disclose the same to any Bank or any
        other person.

17.1.5  For the purposes of this Agreement, the Agent shall be deemed not to
        have any actual knowledge or actual notice of the contents of any
        information obtained by it or supplied to it by or on behalf of any
        member of the Group other than the contents of information obtained by
        or supplied to it as Agent for the Banks pursuant to or in connection
        with this Agreement.

17.2    Payments and Information Received

        The Agent will promptly account to the Lending Office of each Bank for
        such Bank's due proportion of all sums received by the Agent for such
        Bank's account, whether by way of repayment or prepayment of principal
        or payment of interest, fees or otherwise. The Agent shall provide the
        Banks with all information and copies of all notices which by the terms
        of this Agreement are to be provided or given to the Banks. The Agent
        may retain for its own use and benefit (and shall not be liable to
        account to any of the Banks for all or any part of) any sums received by
        it by way of agency or management or arrangement fees or by way of
        reimbursements of expenses incurred by it.

17.3    Defaults

        The Agent shall not be obliged to take any steps to ascertain whether
        any Default (other than a default in repayment of principal or in
        payment of interest, fees or other sums due pursuant to this Agreement)
        or Default Occurrence has happened or exists and, until the Agent shall
        have received express notice to the contrary from a Borrower or any
        Bank, the Agent shall be entitled to assume that no Default (other than
        as aforesaid) or Default Occurrence has happened or exists. Upon receipt
        of such notice the Agent shall promptly inform the Banks.

17.4    Assumptions

        The Agent shall be entitled to rely on any communication or document
        believed by it to be genuine and correct and to have been communicated
        or signed by the person by whom it purports to be communicated or signed
        and shall not be liable to any of the parties to this Agreement for any
        of the consequences of such reliance.

17.5    Legal Proceedings

        The Agent shall not be obliged to take or commence any legal action or
        proceeding against a Borrower or any other person arising out of or in
        connection with the Financing Documents until it shall have been
        indemnified or secured to its satisfaction against any and all costs,
        claims and expenses (including, but to limited to, any costs award which
        may be made against it as a result of any such legal action or
        proceeding not being successful) which it may expend or incur in such
        legal action or proceeding.



<PAGE>

17.6    No Liability

        Neither the Agent nor any of its directors, employees or agents shall be
        liable for any action taken or omitted to be taken by it or any of them
        under or in connection with the Financing Documents unless caused by its
        or their gross negligence or wilful misconduct. The Agent shall not be
        responsible for any statements, representations or warranties in this
        the Financing Documents or for any information supplied or provided or
        hereafter to be supplied or provided to any of the Banks and the Working
        Capital Bank by the Agent, in respect of a Borrower or any other person
        or for any other matter relating to the Facilities or the Financing
        Documents or for the execution, effectiveness, genuineness, validity,
        enforceability or sufficiency of such documents or any of the other
        documents referred to herein or therein or for the recoverability of all
        or any of the Loans or any of the other sums to become due and payable
        pursuant hereto.

17.7    Credit Decisions

17.7.1  Each Bank and the Working Capital Bank acknowledges that it has,
        independently and without reliance on the Agent and based on such
        documents and information as it deemed appropriate, made its own
        analysis of the transaction reached its own decision to enter into, this
        Agreement and made its own investigation of the financial condition and
        affairs of the Borrowers and its own appraisal of the creditworthiness
        of the Borrowers.

17.1.2  Save as specifically provided herein, the Agent shall not be under nay
        duty or obligation, either initially or on a continuing basis, to
        provide any Bank or the Working Capital Bank with any credit information
        or other information with respect to the financial condition of the
        Company or the Borrower of which is otherwise relevant to the
        Facilities.

17.7.3  Each Bank and the Working Capital Bank further acknowledges and confirms
        that it will, independently and without reliance on the Agent and based
        on such documents and information as it shall deem appropriate at the
        time, make its own decisions in taking or not taking action under the
        Financing Documents.

17.8    Advisers

        The Agent shall be entitled to obtain and rely on the advice of any
        professional advisers selected by it given in connection with the
        Financing Documents or any of the matters contemplated hereby or
        thereby, and shall not be liable to any of the Banks and the Working
        Capital Bank for any of the consequences of such reliance.

17.9    Relationship with Banks

17.9.1  In performing its functions and duties under this Agreement, the Agent
        shall act solely as the agent for the Banks and shall not assume or be
        deemed to have assumed any obligation as agent or trustee for, or any
        relationship of agency or trust with or the Borrowers.



<PAGE>

17.9.2  Neither the Agent nor any Bank nor the Working Capital Bank shall be
        under any liability or responsibility of any kind to the Borrowers or
        any of the other Banks arising out of or in relation to any failure or
        delay in performance or breach by an other Bank or Banks and the Working
        Capital Bank or, as the case may be, a Borrower of any of its or their
        respective obligations pursuant to the Financing Documents.

17.10   Agent's position as a Bank

        With respect to its own Participation in the Loans, the Agent shall have
        the same rights and powers under and in respect of the Financing
        Documents as though it were not also acting as agent and/or trustee for
        the Banks. The Agent may, without liability to account, accept deposits
        from, lend money to and generally engage in any kind of banking or trust
        business with or for any Borrower as if it were not the agent or the
        trustee for the Banks.

17.11   Indemnity

        Each of the Banks agrees to indemnify the Agent (to the extent not
        reimbursed by the Borrower) rateably according to the Banks' respective
        Commitments from and against any and all liabilities, obligations,
        losses, damages, penalties, actions, judgments, suits, costs, expenses
        and disbursements of any kind or nature whatsoever (except in respect of
        any agency, management or other fee due to the Agent) which may be
        imposed on, incurred by or asserted against the Agent in its capacity as
        agent for the Banks or in any way relating to or arising out of the
        Financing Documents or any action taken or omitted by the Agent in
        enforcing or preserving the rights of the Banks under the Financing
        Documents, provided that no Bank shall be liable for any portion of such
        liabilities, obligations, losses, damages, penalties, actions,
        judgments, suits, costs, expenses or disbursements resulting from the
        Agent's gross negligence or wilful misconduct.

17.12   Resignation

17.12.1 Subject to the appointment and acceptance of a successor Agent as
        provided below, the Agent may resign at any time by giving to the
        Company and each of the Banks not less than 60 days' notice of its
        intention to do so. Upon receipt of such notice of resignation the Banks
        shall appoint as successor Agent any bank or financial institution
        selected by the Company and the Majority Banks which is willing and able
        to act as such agent for the Banks.

17.12.2 If no such successor Agent selected by the Company and the Majority
        Banks shall have accepted such appointment within 20 days after the
        Agent's giving of notice of resignation then the Majority Banks after
        consultation with the Company shall have the right to appoint such a
        successor Agent.

17.12.3 If no such successor Agent shall have been so appointed by the Majority
        Banks and shall have accepted such appointment within 40 days after the
        Agent's giving of notice of resignation then the resigning Agent may,
        after consultation with the 



<PAGE>

        Company, appoint as its successor any reputable and experience bank or
        other financial institution with an office in London.

17.12.4 Any such appointment shall take effect upon notice thereof (which notice
        shall specify the bank in London to which payments shall be made
        thereafter) being given to the Company and each Bank. Thereafter, the
        resigning Agent shall be discharged from any further obligation under
        the Financing Documents and its successor and each of the other parties
        hereto and thereto shall have the same rights and obligations inter se
        as they would have had if such success had been a party to the Financing
        Documents in place of the resigning Agent. The resigning Agent shall
        make over to its successor all such records as its successor requires to
        carry out its duties.

17.13   Change of Office

        The Agent may from time to time in its sole discretion by written notice
        to the Company and each Bank designate a different office in the United
        Kingdom from which its duties as the Agent will thereafter be performed.

17.14   Scope of Duties

        The Agent may (except where the same is required by the express
        provisions of this Agreement to be authorised by all the Banks or the
        Majority Creditors) grant waivers, vary the terms of the Financing
        Documents and do or omit to do all such acts and things in connection
        therewith as may be authorised in writing by the Majority Banks. Any
        such waiver, variation, act or omission so authorised and effected by
        the Agent shall be binding on all the Banks and the Agent shall be under
        no liability whatsoever in respect of any such waiver, consent,
        variation, act or omission. Except with the prior written agreement of
        all the Banks, nothing in this Clause shall authorise (as between the
        Agent and the Banks) (i) any change in the rate at which any interest or
        commission is payable under this Agreement, (ii) any extension of the
        date for, or alteration in the amount or currency of, the payment of any
        principal, interest, fees or any other amount payable under this
        Agreement, (iii) "Majority Banks" in Clause 1.1, (v) any variation of
        Clause 8, 9 or 15 and this Clause 17 or (vi) any provision of this
        Agreement which requires the consent of all the Banks.

17.15   Consents

        The Agent may at any time upon the application and at the cost of the
        Borrowers and without any consent of any of the Banks (only if and so
        far as its reasonable opinion the interests of the Banks shall not be
        materially prejudiced thereby) give any consent, approval or license
        required on the Agent under the terms of this Agreement, save where this
        Agreement expressly requires that such consent, approval or license
        should be given only with the approval of, or on the instructions of,
        the Banks, the Majority Banks or the Majority Creditors.



<PAGE>

17.16   Evidence

        The Agent may accept a certificate signed by any director of the
        secretary of the Company or any Borrower as to any fact or matter on
        which the Agent may need or wish to be satisfied as sufficient evidence
        thereof and a like certificate that any assets in the opinion of the
        person so certifying have a particular value or produce a particular
        income or are suitable for a particular purpose as sufficient evidence
        that they have that value or produce that income or are so suitable and
        the Agent shall not be bound in any such case to call for further
        evidence or be responsible for any loss that may be occasioned by its
        failing to do so.

17.17   Distribution of Proceeds of Enforcement

17.17.1 In this Clause 17.17 the following expressions shall have the following
        meanings:

        "Bank Outstandings" means, in respect of a Bank (which expression for
        the purposes of this Clause 17.17 shall include the Working Capital
        Bank), the aggregate amount owed to such Bank by way of principal,
        interest, commission and fees in respect of the Facilities, including
        all amounts actually or contingently owed to the Working Capital Bank at
        such time under, or in respect of, the uncommitted Engagements Facility;
        and

        "Total Outstandings" means the aggregate of the Bank Outstandings of
        each Bank.

17.17.2 Subject to the terms of the Intercreditor Agreement on the enforcement
        of all or any of the Security Documents, any amount of enforcement
        proceeds paid to the Agent pursuant to the Intercreditor Agreement shall
        be applied as follows. The Agent shall be entitled to deduct from the
        proceeds of such enforcements its costs, charges and expenses incurred
        in connection with such enforcement together an amount equal to all sums
        due to the Agent hereunder before distributing to each Bank an amount
        equal to the remaining proceeds multiplied by:

                         Bank Outstanding of such Bank
                               Total Outstandings

        where Bank Outstandings, the Working Capital Bank's Outstandings and the
        Total Outstandings are all calculated as at the date of enforcement.

17.17.3 The Agent shall notify each Bank of any proposed distribution and the
        proposed date of distribution and each Bank shall provide to the Agent a
        calculation of what is due to it in respect of the sums referred to in
        Clause 17.17.1. The Agent shall send copies of all such calculations to
        all other Banks and, in the absence of manifest error, the Agent shall
        make the distributions on the basis of such calculations.

17.17.4 If any continent liability incurred in the calculation of Bank's
        Outstandings finally matures or is settled for less than the contingent
        amount provided for in the relevant calculations then the relevant Bank
        shall notify the Agent of that fact and such adjustment shall be made by
        payment by such Bank to the Agent for distribution amongst the Banks as
        may be necessary to put the Banks into the position they



<PAGE>

        would have been in (but taking no account of the time cost of money) had
        the original distribution been made on the basis of the actual as
        opposed to the contingent liability.

17.17.5 The Agent may, at its discretion, accumulate proceeds of realisations on
        an interest bearing account in its own name until there is a minimum of
        (pound)500,000 to distribute under Clause 17.17.2.

17.18   Net Limits

        For the avoidance of doubt, any credit balances taken into account by a
        Bank when operating a net limit in respect of any overdraft under the
        Overdraft Facility shall not be subject to Clause 16.2 and shall, on the
        enforcement of the Security Documents, be applied first in reduction of
        the relevant overdraft provided under the Overdraft Facility to the
        extent taken into account in operating the net limit.

        any of the Financing Documents shall be paid by the Company PROVIDED
        THAT the Agent shall be entitled but not obliged to pay any such duties

        otherwise) by the Agent or a Bank, the amount of that payment shall be
        increased by an amount equal to the amount of VAT which is chargeable in

        Capital Bank in respect of any loss or payment, the calculation of the
        amount payable by way of indemnity or reimbursement shall take account
        of the actual Tax treatment in the hands of such person (as determined
        by the relevant person's auditors) of the amount payable by way of
        indemnity or reimbursement together with the loss or payment in respect
        of which the amount is payable.

        Bank and other Banks that it shall be under the same obligations towards

21.3.3  If any Bank (the "Existing Bank") wishes to transfer all or any part of

<PAGE>
21.3.4  On the date specified in the Transfer Certificate:

        (i)     to the extent that in the Transfer Certificate the Existing Bank
                seeks to transfer its Commitment or Participations, the
                Borrowers and the Existing Bank shall each be released from
                further obligations to each other under this Agreement and their
                respective rights against each other shall be cancelled (such
                rights and obligations being referred to in this Clause 21.3.4
                as "Discharged Rights and Obligations");

        (ii)    the Borrowers and the Bank Transferee shall each assume
                obligations towards each other and/or acquire rights against
                each other which differ from the Discharged Rights and
                Obligations only insofar as the Borrower and the Bank Transferee
                have assumed and/or acquired the same in place of the Borrower
                and the Existing Bank;

        (iii)   the Agent, the Borrowers, the Working Capital Bank, the Bank
                Transferee and the other Banks shall acquire the same rights and
                assume the same obligations among themselves as they would have

                hereunder as a Bank with the rights and/or the obligations
                acquired or assumed by it as a result of the transfer;

        (iv)    a proportion of the Existing Bank's rights under the Security
                Documents equal to the proportion of the Existing Bank's rights
                under this Agreement being transferred, shall automatically be
                transferred to the Bank Transferee; and

        (v)     a proportion of the Existing Bank's rights and obligations under
                the Intercreditor Agreement equal to the proportion of the
                Existing Bank's rights under this Agreement being transferred
                shall automatically be transferred to the Bank Transferee in
                accordance with the terms of the Intercreditor Agreement.

21.3.5  The Agent will promptly complete Transfer Certificates on request by an
        Existing Bank and upon payment by such Existing Bank of a fee of
        (pound)750 to the Agent. The Working Capital Bank, the Borrowers and
        each of the Banks hereby irrevocably authorize the Agent to execute any
        duly completed Transfer Certificate on its behalf provided that such
        authorisation does not extend to the execution of a Transfer Certificate
        on behalf of either the Existing Bank or the Bank Transferee named
        therein.

21.3.6  The Agent shall promptly notify the Company of the receipt and execution
        on its behalf by the Agent of any Transfer Certificate.

        this Agreement following an assignment or transfer by a Bank of any of
        its rights or obligations pursuant to the foregoing provisions of this
        Clause 21 where, in the circumstances existing at the time of such
        assignment or transfer, such greater amount would not have been payable
        but for the assignment or transfer.



<PAGE>

21.4    Disclosure of Information

        The Agent and the Banks may not disclose any information furnished or
        made available to them hereunder by the Borrowers unless such
        information is available in the public domain PROVIDED THAT such
        information may be disclosed to each other, their professional advisers
        and to any actual or potential assignee, transferee or sub-participant
        subject to the condition that each of the same undertakes to the Company
        to keep confidential any such information and not disclose it save in
        accordance with the provisions of this Clause 21.4.

22.     COUNTERPARTS

        This Agreement may be executed in any number of counterparts and all
        such counterparts when executed and taken together shall constitute one
        and the same Agreement.

23.     LAW

        This Agreement shall be governed by, and construed in all respects in
        accordance with, English law.

24.     CURRENCY INDEMNITY

        Any payment or payments made to or for the account of or received by the
        Agent, the Working Capital Bank or any Bank in respect of any monies or
        liabilities due, arising or incurred by any Borrower to the Agent, the
        Working Capital Bank or any Bank in a currency (the "Currency of
        Payment") other than the currency in which the payment should have been
        made pursuant to this Agreement (the "Currency of Obligation") in
        whatever circumstances (including, without limitation, as a result of a
        judgment against such Borrower) and for whatever reason shall constitute
        a discharge to such Borrower to the extent of the Currency of Obligation
        amount which the Agent, the Working Capital Bank or Bank, as the case
        may be, is able on the date or dates of receipt of such payment or
        payments (or if not a Business Day on the next succeeding Business Day)
        to purchase with the Currency of Payment amount in the London foreign
        exchange market. If the amount of the Currency of Obligation which the
        Agent, the Working Capital Bank or that Bank is so able to purchase
        falls short of the amount originally due to the Agent, the Working
        Capital Banks or that Bank, as the case may be, under this Agreement,
        then such Borrower shall indemnify and hold the Agent, the Working
        Capital Banks or that Bank, as the case may be, harmless against any
        loss or damage arising as a result thereof by paying to the Agent, the
        Working Capital Bank or that Bank, as the case may be, that amount in
        the Currency of Obligation certified by the Agent, the Working Capital
        Bank or that Bank, as the case may be, as necessary so to indemnify it.

                                   SCHEDULE 3

                      MANDATORY LIQUID ASSET COSTS FORMULA

(1)     The additional rate relative to an Advance shall, subject as hereinafter
        provided, be calculated in accordance with the following formula:


                         BY + L(Y-X) + S(Y-Z)% per annum
                         --------------------
                           100 - (B+S)

        Where on the day of the application of the formula:

        B =     The percentage of the Agent's eligible liabilities which the
                Bank of England then requires the Agent to Hold on a
                non-interest-bearing deposit account in accordance with its the
                Company ratio requirements.

        Y =     The rate at which Sterling deposits in an amount comparable with
                such Advance are offered by the Agent to leading banks in the
                London Inter-Bank Market at or about 11.00 a.m. on such day for
                the relevant period.

        L =     The percentage of eligible liabilities which (as a result of the
                requirements of the Bank of England) the Agent maintains as
                secured money with members of the London Discount Market
                Association or in certain marketable or callable securities
                approved by the Bank of England, which percentage shall (in the
                absence of evidence that any other figure is appropriate) be
                conclusively presumed to be 5 per cent.

        X =     The rate at which secured Sterling deposits in an amount
                comparable to such Advance may be placed by the Agent with
                members of the London Discount Market Association at or about
                11.00 a.m. on such day for the relevant period or, if greater,
                the rate at which Sterling bills of exchange (of an amount
                comparable to such Advance and of a tenor equal to the relevant
                period) eligible for rediscounting at the Bank of England can be
                discounted in the London Discount Market at or about 11.00 a.m.
                on that day.

        S =     The percentage of the Agent's eligible liabilities which the
                Bank of England requires the Agent to place as a special
                deposit.

        Z =     The percentage interest rate per annum allowed by the Bank of
                England on special deposits.

(2)     For the purposes of this Schedule 3:

        (i)     "eligible liabilities" and "special deposits" shall bear the
                meanings ascribed to them from time to time by the Bank of
                England; and

        (ii)    "relevant period" in relation to each Interest Period means:



<PAGE>

                (a)     if it is 3 monthly or less, that Interest Period; or

                (b)     if it is more than 3 months, 3 months.

(3)     In the application of the above formula, B, Y, L, X, S and Z will be
        included in this formula as figures and not as percentages, e.g., if B =
        0.5% and Y = 15%, BY will be calculated as 0.5 x 15 and not as 0.5% x
        15%.

(4)     The additional rate computed by the Agent in accordance with this
        Schedule 3 shall, if not so already, be rounded upward to 4 decimal
        places.

(5)     In the event of a change in circumstances (including the imposition of
        alternative or additional official requirements) which renders the above
        formula inapplicable, the Agent shall notify Newco of the manner in
        which the additional rate shall thereafter be determined which shall
        reflect the additional costs following such change incurred by the Banks
        at such time and from time to time.

States of America, any and all Obligations of the Borrowers from time to time
owed to the Beneficiaries. The term "Obligations" is used herein in its most
comprehensive sense and includes any and all present and future obligations and
liabilities of the Borrowers of every type and description under any of the
Financing Documents to the Beneficiaries, or any of them, or any of their
successors or assigns, or any Person entitled to indemnification under the



                                    Guaranty

                                       4

Financing Documents, whether for principal, interest, letter of credit or other
reimbursement obligations, cash collateral cover, fees, expenses, indemnities or
other amounts (including attorney's fees and expenses), including without
limitation all Bank Liabilities (as defined in the Inter-Creditor Agreement) and
all Note Holder Liabilities (as defined in the Inter-Creditor Agreement),

in each case whether due or not due, direct or indirect, joint and/or several,
absolute or contingent, voluntary or involuntary, liquidated or unliquidated,
determined or undetermined, now or hereafter existing, renewed or restructured,
whether or not from time to time decreased or extinguished and later increased,
created or incurred, whether or not arising after the commencement of a
proceeding under the Bankruptcy Code (including post-petition interest) and
whether or not allowed or allowable as a claim in any such proceeding, and
whether or not recovery of any such obligation or liability may be barred by a
statute of limitations or such obligation or liability may otherwise be
unenforceable. All Obligations shall be conclusively presumed to have been
created in reliance on this Guaranty. All payments hereunder shall be made on
the same basis as payments by the Borrowers under Section 12.4 of the Credit
Agreement.

          Section 2.2. Continuing and Irrevocable Guaranty. This is a continuing
guaranty of the Obligations and may not be revoked and shall not otherwise
terminate unless and until the Obligations have been indefeasibly paid and
performed in full. If notwithstanding the foregoing any Guarantor shall have any
right under Applicable Law to terminate this Guaranty prior to indefeasible
payment in full of the Obligations, no such termination shall be effective until
noon the next Business Day after the Security Trustee shall receive written
notice thereof, signed by such Guarantor. Any such termination shall not affect
this Guaranty in relation to (a) any Obligation that was incurred or arose prior
to the effective time of such notice, (b) any Obligation incurred or arising
after such effective time where such Obligation is incurred or arises either
pursuant to commitments existing at such effective time or incurred for the
purpose of protecting or enforcing rights against any Borrower, any Guarantor or
other Guarantor of or other Person directly or indirectly liable on the
Obligations or any portion thereof (an "Other Guarantor") or any security
("Collateral") given for the Obligations or any other guaranties of the
Obligations or any portion thereof (an "Other Guaranty"), (c) any renewals,
extensions, readvances, modifications or rearrangements of any of the foregoing
or (d) the liability of any other Guarantor hereunder. Without limiting the
generality of the foregoing, if any part of the Obligations arises under
revolving credit facilities, then even if the Borrowers are no longer entitled
to further credit (as a result of the purported termination hereof or
otherwise), no termination of this Guaranty shall in any event be effective to
reduce the obligations of any Guarantor hereunder with respect to any extensions
of credit that may thereafter be made to the Borrowers by the Beneficiaries to
the extent that the outstanding amount of such credit (including letter of
credit and other contingent exposure), together with all other Obligations then
outstanding, does not exceed the aggregate amount of all Obligations outstanding
as of the time any termination of this Guarantor becomes effective.

          Section 2.3. Nature of Guaranty. The liability of each Guarantor
hereunder is independent of and not in consideration of or contingent upon the
liability of any Borrower or any other Obligor and a separate action or actions
may be brought and prosecuted against any Guarantor, whether or not any action
is brought or prosecuted against any Borrower or any other Obligor or whether
any Borrower or any other Obligor is joined in any such action or actions. This
Guaranty shall be construed as a continuing, absolute and unconditional guaranty
of payment (and not merely of collection) without regard to:

          2.3.1. the legality, validity or enforceability of any of the
Financing Document, any of the Obligations, any Lien or Collateral or any Other
Guaranty;

          2.3.2. any defense (other than payment), set-off or counterclaim that
may at any time be available to any Borrower or any other Obligor against, and
any right of set-off at any time held by, any Beneficiary; or

          2.3.3. any other circumstance whatsoever (with or without notice to or
knowledge of any Guarantor or any other Obligor), whether or not similar to any
of the foregoing, that constitutes, or might be construed to constitute, an
equitable or legal discharge of any Borrower or any other Obligor, in bankruptcy
or in any other instance.

          Section 2.4. Authorization. Each Guarantor authorizes each
Beneficiary, without notice to or further assent by such Guarantor, and without
affecting any Guarantor's liability hereunder (regardless of whether any
subrogation or similar right that such Guarantor may have or any other right or
remedy of such Guarantor is extinguished or impaired), from time to time to:

          2.4.1. permit any Borrower to increase or create Obligations, or
terminate, release, compromise, subordinate, extend, accelerate or otherwise
change the amount or time, manner or place of payment of, or rescind any demand
for payment or acceleration of, the Obligations or any part thereof (including
increasing or decreasing the rate of interest thereon), or otherwise amend the
terms and conditions of any of the Financing Documents or any provision thereof;

          2.4.2. take and hold Collateral from any Borrower or any other Person,
perfect or refrain from perfecting a Lien on such Collateral, and exchange,
enforce, subordinate, release (whether intentionally or unintentionally), or
take or fail to take any other action in respect of, any such Collateral or Lien
or any part thereof;

          2.4.3. exercise in such manner and order as it elects in its sole
discretion, fail to exercise, waive, suspend, terminate or suffer expiration of,
any of the remedies or rights of such Beneficiary against any Borrower or any
other Obligor in respect of any Obligations or any Collateral;

          2.4.4. release, add or settle with any Obligor in respect of this
Guaranty, any Other Guaranty or the Obligations;

<PAGE>

          2.4.5. accept partial payments on the Obligations and apply any and
all payments or recoveries from any Obligor or Collateral to such of the
Obligations as each Beneficiary may elect in its sole discretion, whether or not
such Obligations are secured or guaranteed;

          2.4.6. refund at any time, at such Beneficiary's sole discretion, any
payments or recoveries received by such Beneficiary in respect of any
Obligations or Collateral; and

          2.4.7. otherwise deal with any Borrower, any other Obligor and any
Collateral as such Beneficiary may elect in its sole discretion.

          Section 2.5. Certain Waivers. Each Guarantor waives:

          2.5.1. the right to require the Beneficiaries to proceed against any
Borrower or any other Obligor, to proceed against or exhaust any Collateral or
to pursue any other remedy in any Beneficiary's power whatsoever and the right
to have the property of the Borrowers or any other Obligor first applied to
the discharge of the Obligations;

          2.5.2. all rights and benefits under any applicable law purporting to
reduce a guarantor's obligations in proportion to the obligation of the
principal or providing that the obligation of a surety or guarantor must neither
be larger nor in other respects more burdensome than that of the principal;

          2.5.3. the benefit of any statute of limitations affecting the
Obligations or any Guarantor's liability hereunder and of Section 359.5 of the
California Code of Civil Procedure;

          2.5.4. any requirement of marshaling or any other principle of
election of remedies and all rights and defenses arising out of an election of
remedies by any Beneficiary, even though that election of remedies, such as
nonjudicial foreclosure with respect to the security for a guaranteed
obligation, has destroyed any Guarantor's rights of subrogation and
reimbursement against any Borrower by the operation of Section 580d of the
California Code of Civil Procedure or otherwise;

          2.5.5. any right to assert against any Beneficiary any defense (legal
or equitable), set-off, counterclaim and other right that any Guarantor may now
or any time hereafter have against any Borrower or any other Obligor;

          2.5.6. presentment, demand for payment or performance (including
diligence in making demands hereunder), notice of dishonor or nonperformance,
protest, acceptance and notice of acceptance of this Guaranty, and all other
notices of any kind, including (i) notice of the existence, creation or
incurrence of new or additional Obligations, (ii) notice of any action taken or
omitted by the Beneficiaries in reliance hereon, (iii) notice of any default by
the Borrowers or any other Obligor, (iv) notice that

<PAGE>

any portion of the Obligations is due, (v) notice of any action against any
Borrower or any other Obligor, or any enforcement of other action with respect
to any Collateral, or the assertion of any right of any Beneficiary hereunder;

          2.5.7 all defenses that at any time may be available to any Guarantor
by virtue of any valuation, stay, moratorium or other law now or hereafter in
effect;

          2.5.8. any rights, defenses and other benefits any Guarantor may have
by reason of any failure of any Beneficiary to hold a commercially reasonable
public or private foreclosure sale or otherwise to comply with applicable law in
connection with a disposition of the Collateral; and

          2.5.9. without limiting the generality of the foregoing or any other
provision hereof, all rights and benefits under California Civil Code Sections
2810, 2819, 2839, 2845, 2848, 2849, 2850, 2899, and 3433 or any similar
provisions of applicable law.

          Section 2.6. Subrogation; Certain Agreements.

          2.6.1 EACH GUARANTOR WAIVES ANY AND ALL RIGHTS OF SUBROGATION,
INDEMNITY, CONTRIBUTION OR REIMBURSEMENT, AND ANY AND ALL BENEFITS OF AND RIGHTS
TO ENFORCE ANY POWER, RIGHT OR REMEDY THAT ANY BENEFICIARY MAY NOW OR HEREAFTER
HAVE IN RESPECT OF THE OBLIGATIONS AGAINST ANY BORROWER OR ANY OTHER OBLIGOR,
ANY AND ALL BENEFITS OF AND RIGHTS TO PARTICIPATE IN ANY COLLATERAL, WHETHER
REAL OR PERSONAL PROPERTY, NOW OR HEREAFTER HELD BY ANY BENEFICIARY, AND ANY AND
ALL OTHER RIGHTS AND CLAIMS (AS DEFINED IN THE BANKRUPTCY CODE) ANY GUARANTOR
MAY HAVE AGAINST ANY BORROWER OR ANY OTHER OBLIGOR, UNDER APPLICABLE LAW OR
OTHERWISE, AT LAW OR IN EQUITY, BY REASON OF ANY PAYMENT HEREUNDER, UNLESS AND
UNTIL THE OBLIGATIONS SHALL HAVE BEEN PAID IN FULL. Without limitation, the
Guarantors shall exercise no voting rights, shall file no claim, and shall not
participate or appear in any bankruptcy or insolvency case involving any
Borrower with respect to the Obligations unless and until all the Obligations
shall have been paid in full. If, notwithstanding the foregoing, any amount
shall be paid to any Guarantor on account of any such rights at any time, such
amount shall be held in trust for the benefit of the Beneficiaries and shall
forthwith be paid to the Security Trustee to be held as Collateral or credited
and applied in accordance with the terms of the Inter-Creditor Agreement and the
other Financing Documents upon the Obligations, whether matured, unmatured,
absolute or contingent, in the discretion of the Security Trustee.

          2.6.2. Each Guarantor assumes the responsibility for being and keeping
itself informed of the financial condition of each Borrower and each other
Obligor and of all other circumstances bearing upon the risk of nonpayment of
the Obligations that 



                                    Guaranty

                                        8
<PAGE>

diligent inquiry would reveal, and agrees that the Beneficiaries shall have no
duty to advise any Guarantor of information regarding such condition or any such
circumstances.

          Section 2.7. Bankruptcy No Discharge.

          2.7.1. Without limiting Section 2.3., this Guaranty shall not be
discharged or otherwise affected by any bankruptcy, reorganization or similar
proceeding commenced by or against any Borrower or any other Obligor, including
(i) any discharge of, or bar or stay against collecting, all or any part of the
Obligations in or as a result of any such proceeding, whether or not assented to
by any Beneficiary, (ii) any disallowance of all or any portion of any
Beneficiary's claim for repayment of the Obligations, (iii) any use of cash or
other collateral in any such proceeding, (iv) any agreement or stipulation as to
adequate protection in any such proceeding, (v) any failure by any Beneficiary
to file or enforce a claim against any Borrower or any other Obligor or its
estate in any bankruptcy or reorganization case, (vi) any amendment,
modification, stay or cure of any Beneficiary's rights that may occur in any
such proceeding, (vii) any election by any Beneficiary under Section 1111(b)(2)
of the Bankruptcy Code, or (viii) any borrowing or grant of a Lien under Section
364 of the Bankruptcy Code. Each Guarantor understands and acknowledges that by
virtue of this Guaranty, it has specifically assumed any and all risks of any
such proceeding with respect to each Borrower and each other Obligor.

          2.7.2. Notwithstanding anything to the contrary herein contained, this
Guaranty (and any Lien on the Collateral securing this Guaranty or the
Obligations) shall continue to be effective or be reinstated, as the case may
be, if at any time any payment, or any part thereof, of any or all of the
Obligations is rescinded, invalidated, declared to be fraudulent or preferential
or otherwise required to be restored or returned by any Beneficiary in
connection with any bankruptcy, reorganization or similar proceeding involving
any Borrower, any other Obligor or otherwise, if the proceeds of any Collateral
are required to be returned by such Beneficiary under any such circumstances, or
if any Beneficiary elects to return any such payment or proceeds or any part
thereof in its sole discretion, all as though such payment had not been made or
such proceeds not been received. Without limiting the generality of the
foregoing, if prior to any such rescission, invalidation, declaration,
restoration or return, this Guaranty shall have been canceled or surrendered (or
if any Lien or Collateral shall have been released or terminated in connection
with such cancellation or surrender), this Guaranty (and such Lien and
Collateral) shall be reinstated in full force and effect, and such prior
cancellation or surrender shall not diminish, discharge or otherwise affect the
obligations of the Guarantors in respect of the amount of the affected payment
or application of proceeds (or such Lien or Collateral).

          Section 2.8. Subordination.

          2.8.1. Each Guarantor hereby absolutely subordinates, both in right of
payment and in time of payment, any and all present or future obligations and
liabilities



                                    Guaranty

                                       9
<PAGE>

of any Borrower and each other Obligor to such Guarantor ("Subordinated Debt"),
to the prior payment in full in cash of the Obligations, whether or not such
Subordinated Debt constitutes or arises out of any subrogation, reimbursement,
contribution, indemnity or similar right attributable to this Guaranty. If,
whether or not at any Beneficiary's request, any Guarantor shall receive, prior
to payment in full in cash of all Obligations, payment of any sum from any
Borrower or any other Obligor upon any Subordinated Debt, any such sum shall be
received by such Guarantor as trustee for the Beneficiaries and shall forthwith
be paid over to the Security Trustee on account of the Obligations, without
reducing or affecting in any manner the liability of any Guarantor under this
Guaranty.

          2.8.2. Each Guarantor shall file in any bankruptcy or reorganization
or similar proceeding in which the filing of claims is required by applicable
law, all claims that such Guarantor may have against any Borrower or other
Obligor (or its nominee) relating to any Subordinated Debt. If the Guarantor
does not file any such claim, the Security Trustee (or its nominee) as
attorney-in-fact for the Guarantor is hereby authorized to do so in the name of
such Guarantor. Each Guarantor agrees that, in connection with any such
proceeding, it shall not contest or oppose the treatment of claims of the
Beneficiaries in any plan of reorganization or otherwise and it shall vote any
claims that exist by virtue of this Guaranty or the Subordinated Debt in
connection with any plans of reorganization or otherwise, as may be requested by
the Security Trustee.

          2.8.3. Each Guarantor hereby grants the Security Trustee a power of
attorney for the purposes set forth in this Section 2.8. Such power of attorney
is coupled with an interest and cannot be revoked.

          Section 2.9. Maximum Liability of Guarantors. The obligations of each
Guarantor hereunder shall be limited to an aggregate amount equal to the largest
amount that would not render its obligations hereunder subject to avoidance
under Section 548 of the Bankruptcy Code or any applicable provisions of
comparable state law.

          Section 2.10. Right of Contribution. In order to provide for just and
equitable contribution among the Guarantors and any Other Guarantors (for
purposes of this Section only, each Guarantor and each Other Guarantor is
referred to as a "Guarantor"), in connection with the execution of this
Guaranty, the Guarantors have agreed among themselves that if any Guarantor
satisfies some or all of the Obligations (a "Funding Guarantor"), the Funding
Guarantor shall be entitled to contribution from the other Guarantors that have
positive Maximum Net Worth (as defined below) for all payments made by the
Funding Guarantor in satisfying the Obligations, so that each Guarantor that
remains obligated under this Guaranty or any Other Guaranty at the time
that a Funding Guarantor makes such payment (a "Remaining Guarantor") and has a
positive Maximum Net Worth shall bear a portion of such payment equal to the
percentage that such Remaining Guarantor's Maximum Net Worth bears to the
aggregate Maximum Net Worth of all Remaining Guarantors that have positive
Maximum Net Worth.

<PAGE>

          As used herein, "Net Worth" means, with respect to any Guarantor, the
amount, as of the respective date of calculation, by which the sum of a Person's
assets (including subrogation, indemnity, contribution, reimbursement and
similar rights that the Guarantor may have), determined on the basis of a "fair
valuation" or their "fair saleable value" (whichever is the applicable test
under Section 548 and other relevant provisions of the Bankruptcy Code and the
relevant state fraudulent conveyance or transfer laws), is greater than the
amount that will be required to pay all of such Person's debts, in each case
matured or unmatured, contingent or otherwise, as of the date of calculation,
but excluding liabilities arising under this Guaranty or any Other Guaranty and
excluding, to the maximum extent permitted by applicable law with the objective
of avoiding rendering such Person insolvent, liabilities subordinated to the
Obligations arising out of loans or advances made to such Person by any other
Person. "Maximum Net Worth" means, with respect to any Guarantor, the greatest
of the Net Worth of such Guarantor calculated as of the following dates: (A) the
date on which such Person becomes a Guarantor, (B) the date on which such
Guarantor expressly reaffirms this Guaranty or the Other Guaranty to which it
is a party, (C) the date on which demand for payment is made on such Guarantor
hereunder or under such Other Guaranty, (D) the date on which payment is made by
such Guarantor hereunder or thereunder or (E) the date on which any judgment,
order or decree is entered requiring such Guarantor to make payment hereunder or
in respect hereof or under or in respect of such Other Guaranty. The meaning of
the terms "fair valuation" and "fair saleable value" and the calculation of
assets and liabilities shall be determined and made in accordance with the
relevant provisions of the Bankruptcy Code and applicable state fraudulent
conveyance or transfer laws.

                                   ARTICLE 3.

                         REPRESENTATIONS AND WARRANTIES

          Each Guarantor represents and warrants that all representations and
warranties made with respect to it, its assets and its obligations in Section
13.2 of the Credit Agreement are true and correct and makes the following
additional representations and warranties, all of which shall survive until
termination of this Guaranty pursuant to Section 2.2.

          Section 3.1. Financial Benefit. Each Guarantor hereby acknowledges and
warrants it has derived or expects to derive a financial advantage from each
loan or other extension of credit and each renewal, extension, release of
Collateral, or other relinquishment of legal rights, made or granted or to be
made or granted by the Beneficiaries in connection with the Obligations. After
giving effect to this Guaranty and the other Financing Documents to which any
Guarantor is a party, and the transactions contemplated hereby and thereby, each
Guarantor is not Insolvent or left with assets or capital that is unreasonably
small in relation to its business or the Obligations. "Insolvent" means, with
respect to any Guarantor, that (a) determined on the basis of a "fair valuation"
or their "fair saleable value" (whichever is the applicable test under



                                    Guaranty

                                       11
<PAGE>

Section 548 and other relevant provisions of the Bankruptcy Code and the
relevant state fraudulent conveyance or transfer laws) the sum of such
Guarantor's assets is less than its debts, or (b) such Guarantor is generally
not paying its debts as they become due.

          Section 3.2. Review of Documents; Understanding With Respect to
Waivers. Each Guarantor hereby acknowledges that it has copies of and is fully
familiar with the Credit Agreement, the U.S. Loan Notes and each other Financing
Document. Each Guarantor warrants and agrees that each waiver set forth in this
Guaranty is made with such Guarantor's full knowledge of its significance and
consequences and after opportunity to consult with counsel of its own choosing
and that, under the circumstances, each such waiver is reasonable and should not
be found contrary to public policy or law.

                                   ARTICLE 4.

                                  MISCELLANEOUS

          Section 4.1. Expenses. Each Guarantor shall pay to the Security
Trustee any and all costs and expenses, (including attorneys' fees and
expenses), that any Beneficiary may incur in connection with (a) the collection
of all sums guaranteed hereunder or (b) the exercise or enforcement of any of
the rights, powers or remedies of the Beneficiaries under this Guaranty or
applicable law. All such amounts and all other amounts payable hereunder shall
be payable on demand, together with interest at the Default Rate, from and
including the due date to and excluding the date of payment.

          Section 4.2. Amendments and Other Modifications. No amendment of any
provision of this Guaranty (including a waiver thereof or consent relating
thereto) shall be effective unless the same shall be in writing and signed by
the Security Trustee. Any waiver or consent relating to any provision of this
Guaranty shall be effective only in the specific instance and for the specific
purpose for which given. No notice to or demand on any Guarantor in any case
shall entitle such Guarantor to any other or further notice or demand in similar
or other circumstances.

          Section 4.3. Cumulative Remedies; Failure or Delay. The rights and
remedies provided for under this Guaranty are cumulative and are not exclusive
of any rights and remedies that may be available to the Beneficiaries under
applicable law or otherwise. No failure or delay on the part of any Beneficiary
in the exercise of any power, right or remedy under this Guaranty shall impair
such power, right or remedy or shall operate as a waiver thereof, nor shall any
single or partial exercise of any such power, right or remedy preclude other or
further exercise of such or any other power, right or remedy.

          Section 4.4. Notices, Etc. All notices and other communications under
this Guaranty shall be in writing and shall be personally delivered or sent by
prepaid courier, by overnight, registered or certified mail (postage prepaid),
or by prepaid telex,

telecopy or telegram, and shall be deemed given when received by the intended
recipient thereof. Unless otherwise specified in a notice given in accordance
with the foregoing provisions of this Section, all notices and other
communications shall be given to the parties hereto at their respective
addresses (or to their respective telex or telecopier numbers) indicated on
Schedule 4.4.

          Section 4.5. Successors and Assigns. This Guaranty and each amendment
hereof shall be binding upon and, subject to the next sentence, inure to the
benefit of each Guarantor, the Beneficiaries and their respective successors and
assigns. The Guarantor shall not assign any of its rights or obligations
hereunder without the prior written consent of the Security Trustee. The benefit
of this Guaranty shall automatically pass with any assignment of the Obligations
(or any portion thereof), to the extent of such assignment.

          Section 4.6. Choice of Forum.

          4.6.1. Each of the Guarantors irrevocably agrees for the benefit of
each of the Beneficiaries 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 Guaranty (and the other
Financing Documents) and, for such purposes, irrevocably submits to the
jurisdiction of such courts. Each of the Guarantors irrevocably agrees that the
courts of the State of New York and the courts of the United States of America
in New York 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 Guaranty (and the other Financing Documents) and, for such purposes,
irrevocably submits to the jurisdiction of such courts. Each of the Guarantors
irrevocably waives any objection which it might now or hereafter have to the
courts referred to in this Section 4.6.1 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 Guaranty and the Financing Documents
and agrees not to claim that any such court is not a convenient or appropriate
forum.

          IN ANY ACTION AGAINST ANY GUARANTOR, SERVICE OF PROCESS MAY BE MADE
UPON SUCH GUARANTOR BY DELIVERY OR BY REGISTERED OR CERTIFIED MAIL, RETURN
RECEIPT REQUESTED, TO ITS ADDRESS INDICATED IN SCHEDULE 4.4., WHICH SERVICE
SHALL BE DEEMED SUFFICIENT FOR PERSONAL JURISDICTION AND SHALL BE DEEMED
EFFECTIVE UPON RECEIPT, IN THE CASE OF DELIVERY, AND 10 DAYS AFTER MAILING, IN
THE CASE OF MAILING. Each Guarantor hereby irrevocably appoints CT Corporation
Systems (the "Process Agent"), with offices on the date hereof in New York, New
York, as Process Agent to receive for and on behalf of such Guarantor service of
process in the County of New York relating to this Agreement. SERVICE OF PROCESS
IN ANY ACTION OR PROCEEDING AGAINST ANY GUARANTOR MAY BE MADE ON THE PROCESS

METHOD OF SERVICE PROVIDED FOR UNDER APPLICABLE LAWS IN EFFECT IN THE STATE OF
NEW YORK, AND THE PROCESS AGENT IS HEREBY AUTHORIZED AND DIRECTED TO ACCEPT SUCH
SERVICE FOR AND ON BEHALF OF SUCH GUARANTOR AND TO ADMIT SERVICE WITH RESPECT
THERETO. SUCH SERVICE UPON THE PROCESS AGENT SHALL BE DEEMED EFFECTIVE PERSONAL

NOTWITHSTANDING ANY FAILURE OF THE PROCESS AGENT TO MAIL COPIES OF SUCH LEGAL

Process Agent pursuant to this Section, a copy of the summons and complaint or
other legal process served upon it, by registered mail, return receipt
requested, at such Guarantor's address set forth in Schedule 4.4., or to such
other address as such Guarantor may notify the Process Agent in writing. Each
Guarantor agrees that it will at all times maintain a process agent to receive
service of process in the County of New York on its behalf with respect to this
Agreement. If for any reason the Process Agent or any successor thereto shall no
longer serve as such process agent or shall have changed its address without
notification thereof to the Beneficiaries, such Guarantor, immediately after
gaining knowledge thereof, irrevocably shall appoint a substitute process agent
acceptable to the Security Trustee in the County of New York and advise the
Security Trustee thereof.

          4.6.2. The submission to the jurisdiction of the courts referred to in
Section 4.6.1 shall not (and shall not be construed as to) limit the right of
the Beneficiaries or any of them to take proceedings against any of the
Guarantors 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.

          Section 4.7. Set-Off. In addition to any rights now or hereafter
granted under applicable law and not by way of limitation of any such rights,
upon the occurrence and during the continuation of any Default, each
Beneficiary, each holder or transferee of any Obligations or any Person with any
interest therein is hereby irrevocably authorized by each Guarantor, at any time
or from time to time, without notice to such Guarantor or to any other Person,
any such notice being hereby expressly waived, to set off and to appropriate and
to apply any and all deposits (general or special, including certificates of
deposit, whether matured or unmatured, but not including trust accounts) and any
other indebtedness, in each case whether direct or indirect or contingent or
matured or unmatured at any time held or owing by such Beneficiary, such holder,
such transferee or such other Person, to or for the credit or the account of
such Guarantor, against and on account of the obligations of such Guarantor to
the Beneficiaries, such holder, such transferee, or such other Person under this
Guaranty or the other Financing Documents to which such Guarantor is a party,
irrespective of whether or not such Beneficiary, such

payment and although such obligations may be contingent and unmatured.

          Section 4.8. Currency of Obligations and Payments. The dollar is the
currency of account and payment for each and every sum at any time due from the
Guarantors hereunder; provided that any amount of Obligations expressed to be
payable in a currency other than dollars shall be paid in that other currency.
If any sum due from any Guarantor under this Guaranty (or any sum due from any
Borrower under any Financing Document in respect of which any Guarantor is
obligated hereunder) or any order or judgment given or made in relation thereto
has to be converted from the currency (the "first currency") in which the same
is payable thereunder or under such order or judgment into another currency (the
"second currency") for the purpose of (i) making or filing a claim or proof
against such Guarantor, (ii) obtaining an order or judgment in any court or
other tribunal or (iii) enforcing any order or judgment given or made in
relation hereto, the Guarantors shall indemnify and hold harmless the
Beneficiaries from and against any loss suffered as a result of any discrepancy
between (a) the rate of exchange used for such purpose to convert the sum in
question from the first currency into the second currency and (b) the rate or
rates of exchange at which such person may in the ordinary course of business
purchase the first currency with the second currency upon receipt of a sum paid
to in satisfaction, in whole or in part, of any such order, judgment, claim or
proof.

          Section 4.9. Application of Payments and Collections. In the case of
any payments by or collection from any Guarantor hereunder, the proceeds of such
payment or collection shall be applied in the manner set forth in Clause 5 of
the Inter-Creditor Agreement.

          Section 4.10. Execution in Counterparts. This Guaranty may be executed
in any number of counterparts, each of which counterparts, when so executed and
delivered, shall be deemed to be an original and all of which counterparts,
taken together, shall constitute but one and the same Guaranty.

          Section 4.11. Complete Agreement. This Guaranty, together with the
exhibits and schedules hereto and other Financing Documents, is intended by the
parties as the final expression of their agreement regarding the subject matter
hereof and as a complete and exclusive statement of the terms and conditions of
such agreement.

          Section 4.12. Limitation of Liability. No claim shall be made by any
Guarantor against any Beneficiary or the affiliates, directors, officers,
employees or agents of any Beneficiary for any special, indirect, consequential
or punitive damages in respect of any claim for breach of contract or under any
other theory of liability arising out of or related to the transactions
contemplated by this Guaranty, or any act, omission or event occurring in
connection therewith; and each Guarantor waives, releases and agrees not to sue
upon any claim for any such damages, whether or not accrued and whether or not
known or suspected to exist in its favor.

Interest; Absence of Other Liens.

          3.2.1. Each Pledgor has good and marketable title to all Collateral.

                            COVENANTS AND AGREEMENTS

          Section 4.1. Delivery of Pledged Collateral, Etc.

          4.1.1. On the date hereof, each Pledgor is delivering to the Security
Trustee all Collateral consisting of certificated securities, instruments or the
like the physical possession of which is necessary in order for the Security
Interest to be perfected or delivery of which was requested by the Security
Trustee to assure the priority of the Security Interest therein (such Collateral
being "Pledged Collateral"). Each Pledgor shall deliver to the Security Trustee
promptly after acquisition thereof all Pledged Collateral acquired after the
date hereof. All Pledged Collateral shall be in suitable form for transfer by
delivery, or be accompanied by duly executed instruments of transfer or
assignment in blank, all in form and substance satisfactory to the Security
Trustee. The Security Trustee shall have the right, at any time in its
discretion and without notice to any Pledgor, to transfer to or to register in
the name of the Security Trustee or its nominee any or all of the Collateral,
subject only to the revocable rights specified in Section 4.7.1. In addition,
the Security Trustee shall have the right at any time to exchange certificates
or instruments representing or evidencing Pledged Collateral for certificates or
instruments of smaller or larger denominations.

          4.1.2. Without limitation of Section 4.1.1., if any Pledgor receives
or becomes entitled to receive any securities issues by any issuer of Pledged
Stock, or any successor thereto, in any manner in substitution for or in
addition to the Pledged Stock, or if any Pledgor shall become entitled to
receive or shall receive any securities or other property in addition to, in
substitution of, as a conversion of, or in exchange for, any of the Pledged
Stock or any other Collateral, such Pledgor shall receive the same as the agent
for the Security Trustee, and shall hold the same in trust for and deliver the
same promptly to the Security Trustee in the exact form in which received,
together with appropriate instruments of transfer or assignments in blank, to be
held by the Security Trustee as Collateral hereunder.

          Section 4.2. Further Assurances. Each Pledgor shall, at its own
expense, perform on request of the Security Trustee, such acts as may be
necessary or advisable in the opinion of the Security Trustee, or that the
Security Trustee may request at any time, to assure the attachment, perfection
and first priority of the Security Interest, to exercise the rights and remedies
of the Secured Parties hereunder or to carry out the intent of this Agreement.

          Section 4.3. Power of Attorney. Each Pledgor hereby irrevocably
appoints the Security Trustee and its employees and agents as such Pledgor's
true and lawful attorneys-in-fact, with full power of substitution, to do (a)
all things required to be 



                                Pledge Agreement

done by such Pledgor under this Agreement or the other Financing Documents, and
(b) to do all things that the Security Trustee may deem necessary or advisable
to assure the attachment, perfection and first priority of the Security Interest
or otherwise to exercise the rights and remedies of the Secured Parties
hereunder or carry out the intent of this Agreement, in each case irrespective
of whether a Default or Default Occurrence then exists (except as otherwise
provided herein) and at the Pledgor's expense. Without limitation, the Security
Trustee and its officers and agents shall be entitled to affix, by facsimile
signature or otherwise, the general or special endorsement of any Pledgor, in
such manner as the Security Trustee shall deem advisable, to any Collateral that
has been delivered to or obtained by the Security Trustee without appropriate
endorsement or assignment, which endorsement shall be effective for all
purposes.

          Section 4.4. Payments of Charges and Claims. Each Pledgor shall pay
(a) all Charges imposed upon any Collateral, and (b) all claims that have become
due and payable and, under Applicable Law, have or may become Liens upon any
Collateral, in each case before any penalty shall be incurred with respect
thereto; provided that, unless foreclosure, levy or similar proceedings shall
have commenced, such Pledgor need not pay or discharge any such Charges to
claims so long as the validity or amount thereof is being contested in good
faith and by appropriate proceedings and so long as adequate reserves therefore
have been established in accordance with generally accepted accounting
principles. If any Pledgor fails to pay or obtain the discharge of any Charge,
claim or Lien required to be paid or discharged under this Section and asserted
against any material portion of the Collateral, the Security Trustee may, at any
time and from time to time, in its sole discretion and without waiving or
releasing any obligation of such Pledgor under this Agreement or the other
Financing Documents or waiving any Default or Event of Default, make such
payment, obtain such discharge or take such other action with respect thereto as
the Security Trustee deems advisable; provided, however, that the Security
Trustee shall in any event first have given such Pledgor written notice of its
intent to do the same and such Pledgor shall not have, within 15 days of such
notice, paid such claim or obtained to the Security Trustee's satisfaction the
release of the claim or Lien to which such notice relates.

          Section 4.5. Duty of Care.

          4.5.1 The Secured Parties shall have no duty of care with respect to
the Collateral, except that each Secured Party shall have an obligation to
exercise reasonable care with respect to Collateral in its possession; provided
that (i) each Secured Party shall be deemed to have exercised reasonable care if
Collateral in its possession is accorded treatment substantially comparable to
that which such Secured Party accords its own property or treatment
substantially in accordance with actions requested by any Pledgor in writing,
although the Secured Party shall not be obligated to comply with any such
requests, and (ii) the Secured Parties shall have no obligation to take any
actions to preserve rights against other parties with respect to any Collateral.
Without limitation, the Secured Parties shall have no duty with respect to

                                       9

calls, conversions, presentments, maturities, notices or other matters relating
to Collateral, or to maximize interest or other returns with respect thereto.

          4.5.2 Each Pledgor hereby agrees to indemnify and hold harmless each
Secured Party and its directors, officers, employees and agents against any and
all claims, actions, liabilities, costs and expenses of any kind or nature
whatsoever (including reasonable fees and disbursements of counsel) that may be
imposed on, incurred by, or asserted against any of them, in any way relating to
or arising out of this Agreement or any action taken or omitted by them
hereunder, except to the extent a court holds in a final and nonappealable
judgment that they directly resulted from the gross negligence or willful
misconduct of such Persons against and from all such obligations and
liabilities.

          4.5.3 The Security Trustee may at any time deliver or redeliver the
Collateral or any part thereof to any Pledgor and the receipt of any of the same
by such Pledgor shall be complete and full acquittance for the Collateral so
delivered, and the Security Trustee thereafter shall be discharged from any
liability or responsibility therefor.

          Section 4.6 Sale of Collateral; Further Encumbrances. No Pledgor shall
(a) except for dispositions with the prior written consent of the Security
Trustee ("Permitted Sales"), sell, lease or otherwise dispose of any Collateral,
or any interest therein, or (b) grant or suffer to exist any Lien in or on any
Collateral. Concurrently with any Permitted Sale, the Security Interest shall
automatically be released from the Collateral so disposed of; provided, however
that the Security Interest shall continue in the Proceeds thereof. If any
Collateral, or any interest therein, is disposed of in violation of these
provisions, the Security Interest shall continue in such Collateral or interest
notwithstanding such disposition, the Person to which the Collateral or interest
is being transferred shall be bound by this Agreement, and the Pledgor shall
deliver all Proceeds thereof to the Security Trustee to be held as Collateral
hereunder.

          Section 4.7 Voting and Other Consensual Rights; Distributions.

          4.7.1. So long as no Default shall exist:

               4.7.1.1. Each Pledgor shall be entitled to exercise any and all
voting and other consensual rights pertaining to any Collateral, for any purpose
not inconsistent with the terms of this Agreement and the other Financing
Documents; provided, however, that such Pledgor shall not exercise any such
right if it would result in a Default or a Default Occurrence or have a Material
Adverse Effect. Within 10 days of exercising any such right in a manner material
to the Secured Parties, the Pledgor shall give notice to the Security Trustee of
such exercise and the action taken or approved in connection therewith.

               4.7.1.2. Except as otherwise provided herein, each Pledgor shall
be entitled to receive and retain and use free of the Security Interest any and
all cash



                                Pledge Agreement

                                       10

and other property paid or otherwise distributed in respect to the Collateral;
provided, however, that any and all (A) dividends and other distributions paid
or payable other than in cash and (B) cash paid upon or in respect of any of the
Collateral upon or in respect of the liquidation or dissolution of any issuer
thereof or upon or in respect of any distribution of capital or redemption or
exchange of any Collateral shall be delivered to the Security Trustee, in the
exact form received, to be held as Collateral hereunder.

          4.7.2. So long as a Default shall exist, at the sole option of the
Security Trustee, any or all rights of the Pledgors to exercise voting and other
consensual rights and to receive cash and other property distributed in respect
of Collateral as permitted above by this Section, shall cease, at the option of
the Security Trustee, and the Security Trustee, if and when it notified the
Pledgors of the exercise of such option, shall have the sole right to exercise
any or all such voting and other consensual rights and receive and to hold as
Collateral any or all such cash and other property.

          4.7.3. All cash and other property required to be delivered to the
Security Trustee hereunder shall, if received by any Pledgor, be received in
trust for the benefit of the Secured Parties, be segregated from the other
property of the Pledgors, and promptly be delivered to the Security Trustee in
the same form as so received (with any appropriate endorsements of assignments).

          4.7.4. The Security Trustee shall execute and deliver (or cause to be
executed and delivered) to the Pledgors all proxies and other instruments as any
Pledgor may reasonably request for the purpose of enabling such Pledgor to
exercise the voting and other rights which it is entitled to exercise pursuant
to this Section.

          Section 4.8. Registration Rights.

          4.8.1. Each Pledgor agrees that, at any time following the occurrence
of an Acceleration, upon request of the Security Trustee and without expense to
the Secured Parties, it shall at its own expense:

               4.8.1.1. use its best efforts to obtain all necessary
Governmental Approvals for the sale by the Security Trustee of the Collateral or
any part thereof;

               4.8.1.2. prepare, cause to be filed and use its best efforts to
cause to become effective with respect to the Collateral, or any part thereof,
one or more registration statements under the Securities Act of 1933, as amended
(or any similar statute from time to time in effect, the "Securities Act"), on
Form S-1 (or such other form for which the respective issuer of the Collateral
then qualifies and which is available for the sale of the Collateral in
accordance with the intended method of disposition thereof) or one or more
qualifications for exemption from registration or similar documents under the
Securities Act relating to any public offering or sale by the Security Trustee
of such Collateral;

               4.8.1.3. prepare, cause to be filed and use its best efforts to
cause to become effective with respect to the Collateral, or any part thereof,
such qualification statements or similar documents (including any offering
circular) as may be necessary to have such Collateral qualified or registered
under the securities laws of such other jurisdictions (including the applicable
state securities of "Blue Sky" law), and to obtain such Governmental Approvals
for the sale of such Collateral, as the Security Trustee may request in
connection with any such offering or sale;

               4.8.1.4. include in any such registration statement,
qualification statement or similar document all appropriate information relating
to the transaction or transactions in which the Security Trustee proposes to
offer or sell such Collateral;

               4.8.1.5. cause to be filed such pre-effective and post-effective
amendments to each such registration statement, qualification statement or
similar document as may be necessary to prevent any statement therein contained
from being untrue or misleading, and such filing, qualification or registration
to be kept effective for such period as the Security Trustee may deem
appropriate to facilitate the sale or other disposition of such Collateral;

               4.8.1.6. furnish the Security Trustee with such numbers of copies
of each such registration statement, qualification statement or similar
document, and any amendments thereto as the Security Trustee may request;

               4.8.1.7. furnish to the Security Trustee a legal opinion of
counsel acceptable to the Security Trustee as to such matters regarding such
offering or sale as the Security Trustee may reasonable request; and

               4.8.1.8. do such further acts and things as the Security Trustee
may deem necessary to advisable to effectuate the offering and sale by the
Security Trustee of such Collateral in compliance with Applicable Law.

          4.8.2. Each Pledgor agrees to indemnify and hold harmless the Secured
Parties and each underwriter (within the meaning of the Securities Act) acting
in the transaction, and each Person controlling (within the meaning of the
Securities Act) any Secured Party or underwriter, from and against any and all
claims, actions, liabilities, costs and expenses (including legal fees and
expenses) based upon or arising out of any actual or alleged untrue statement of
a material fact contained in any such registration statement, qualification
statement or similar document, or part thereof, or any actual or alleged
omission to state a material fact required to be stated in any such document, or
part thereof, or necessary to make the statements contained therein not
misleading; provided, however, that no Pledgor shall have any liability to any
Person under the foregoing indemnity on account of any actual or alleged untrue
or misleading statement contained in, or any actual or alleged omission from,
any information furnished in writing to such Pledgor by such Person specifically
for use in such document and included thereon in reliance therein.

          4.8.3. If the indemnification provided for in this Section 4.8. is
unavailable to or otherwise insufficient to hold harmless an indemnified party
hereunder in respect of any claims, actions, liabilities, costs or expenses
referred to herein, then each Pledgor, in lieu of indemnifying such indemnified
party, shall contribute to the amount paid or payable by such indemnified party
as a result of such claims, actions, liabilities, costs or expenses in such
proportion as is appropriate to reflect the relative fault of such Pledgor, any
Secured Party and each underwriter in connection with the statements or
omissions that resulted in such claims, actions, liabilities, costs or expenses,
as well as any other relevant equitable considerations.

          4.8.4. Each Pledgor agrees that (i) exercise of registration and other
rights provided in this Section 4.8 is not required in connection with any
exercise of remedies under Article 5 of this Agreement, (ii) such rights may be
exercised or not exercised in the sole discretion of the Security Trustee and
(iii) any request for exercise of such rights may be withdrawn in whole or in
part at any time by the Security Trustee in its sole discretion.

                                   ARTICLE 5.

                    DEFAULT; RIGHTS AND REMEDIES ON DEFAULT

          Section 5.1. Remedies Upon Default. If upon or after the occurrence of
any Default, the Security Trustee elects to exercise remedies under this
Agreement (the occurrence of any such election or other event shall be referred
to as an "Acceleration"), then, whether or not all the Secured Obligations shall
have become immediately due and payable:

          5.1.1. In addition to all its other rights, powers and remedies under
this Agreement and Applicable Law, each Secured Parties shall have, and may
exercise, any and all of the rights, powers and remedies of any secured part
under the UCC, all of which rights, powers and remedies shall be cumulative and
not exclusive, to the extent permitted by Applicable Law.

          5.1.2. The Security Trustee shall have the right, all at the Security
Trustee's sole option and as the Security Trustee in its discretion may deem
necessary or advisable, to do any or all of the following:

               5.1.2.1. to foreclose the Security Interest by any available
judicial procedure or without judicial process; and

               5.1.2.2. to exercise any and all other rights, powers, privileges
and remedies of any owner of the Collateral, including rights of conversion,
exchange or subscription or other rights or upon the exercise by any Pledgor or
the Security Trustee of any right, power or privilege pertaining to the
Collateral, the right to deposit and deliver any and all of the Collateral to
any committee, depositary, transfer agent, registrar or other designated agency
upon such terms and conditions as the Security

Trustee may determine to be appropriate, all without liability except to account
for property actually received by it, but the Security Trustee shall have no
duty to the Pledgors to exercise any such right, power or privilege and shall
not be responsible for any failure to do so or delay in so doing.

               5.1.3. The Security Trustee shall have the right to sell or
otherwise dispose of all or any Collateral at public or private sale or sales,
with such notice as may be required by Section 5.3., in lots or in bulk, at any
exchange, over the counter or at any of the Security Trustee's offices or
elsewhere, for cash or on credit, with or without representations or warranties,
all as the Security Trustee, in its discretion, may deem advisable. The
Collateral need not be present at any such sales. If sale of all or any part of
the Collateral is made on credit or for future delivery, the Collateral so sold
may be retained by the Security Trustee until the sale price is paid by the
purchaser thereof, but the Secured Parties shall not incur any liability in case
any such purchaser shall fail to take up and pay for the Collateral so sold and,
in case of any such failure, such Collateral may be sold again upon like notice.
The Security Trustee shall not be obligated to make any sale of the Collateral
regardless of notice of sale having been given. The Security Trustee may
purchase all or any part of the Collateral at public or, if permitted by
Applicable Law, private sale, and in lieu of actual payment of the purchase
price, the Security Trustee may apply against such purchase price any amount of
the Secured Obligations. Each Pledgor agrees that any sale of Collateral
conducted by the Security Trustee in accordance with the foregoing provisions of
this Section and Section 5.2. shall be deemed to be a commercially reasonable
sale under Section 9-504 of the UCC.

               5.1.4. The Security Trustee shall not be required to register or
qualify any of the Collateral that constitutes securities under applicable state
or federal securities laws in connection with any sale or other disposition
thereof if such disposition is effected in a manner that complies with all
applicable federal and state securities laws. The Security Trustee shall be
authorized at any such disposition (if it deems it advisable to do so) to
restrict the prospective bidders or purchasers to persons who will represent and
agree that they are "accredited investors" or "qualified institutional buyers"
under Applicable Law and purchasing the Collateral for their own account for
investment and not with a view to the distribution or sale thereof. If any such
Collateral is sold at private sale, each Pledgor agrees that if such Collateral
is sold in a manner that the Security Trustee in good faith believes to be
reasonable under the circumstances then existing, then (A) the sale shall be
deemed to be commercially reasonable in all respects, (B) such Pledgor shall not
be entitled to a credit against the Secured Obligations in any amount in excess
of the purchase price, and (C) the Secured Parties shall not incur any liability
or responsibility to any Pledgor in connection therewith, notwithstanding the
possibility that a substantially higher price might have been realized at a
public sale. Each Pledgor recognizes that a ready market may not exist for such
Collateral if it is not regularly traded on a recognized securities exchange,
and that a sale by the Security Trustee of any such Collateral for an amount
substantially less than the price that might have been achieved had the
Collateral been

                                       14

so traded may be commercially reasonable in view of the difficulties that may be
encountered in attempting to sell Collateral that is privately traded.

          Section 5.2. Application of Proceeds.

          5.2.1. Any cash proceeds received by the Security Trustee in respect
of any sale of, collection from, or other realization upon, all of any part of
the Collateral following the occurrence of an Acceleration or otherwise
(including insurance proceeds) may be held by the Security Trustee as Collateral
and/or then or at any time thereafter applied as provided in the Inter-Creditor
Agreement (or as otherwise determined by the Security Trustee if the
Inter-Creditor Agreement is no longer in effect).

          5.2.2. Each Pledgor and any other Person then obligated therefor shall
pay to the Security Trustee on demand any deficiency with regard to the Secured
Obligations that may remain after such sale, collection or realization of, from
or upon the Collateral.

          5.2.3. Payments received from any third party on account of any
Collateral shall not reduce the Secured Obligations until paid in cash to the
Security Trustee. The application of proceeds by the Security Trustee shall be
without prejudice to the Security Trustee's rights as against any Pledgor or
other Persons with respect to any Secured Obligations that may then be or remain
unpaid.

          5.2.4. If at any time after an Acceleration any Pledgor receives any
collections upon or other Proceeds of any Collateral, whether in the form of
cash, notes or otherwise, such Proceeds shall be received in trust for the
Secured Parties and such Pledgor shall keep all such Proceeds separate and apart
from all other funds and property so as to be capable of identification as the
property of the Secured Parties and promptly deliver such Proceeds to the
Security Trustee in the identical form received.

          Section 5.3. Notice. Unless the Collateral is perishable or threatens
to decline speedily in value or is of a type customarily sold on a recognized
market, the Security Trustee will send or otherwise make available to each
Pledgor reasonable notice of the time and place of any public sale or of the
time on or after which any private sale of any Collateral is to be made. Each
Pledgor agrees that any notice required to be given by the Security Trustee of a
sale or other disposition of Collateral, or any other intended action by the
Security Trustee, that is received in accordance with the provisions set forth
in Section 6.4. five days prior to such proposed action shall constitute
commercially reasonable and fair notice thereof to the Pledgers. The Security
Trustee may adjourn any public or private sale from time to time by announcement
at the time and place fixed therefor and such sale may, without further notice,
be made at the time and place to which it was so adjourned. Each Pledgor hereby
waives any right to receive notice of any public or private sale of any
Collateral or other security for the Secured Obligations except as expressly

                                    GENERAL

          Section 6.1. Security Trustee's Expenses, Including Attorneys' Fees.
Regardless of the occurrence of a Default or Default Occurrence, the Pledgors
jointly and severally agree to pay to the Security Trustee any and all advances,
charges, costs and expenses, including the fees and expenses of counsel and any
experts or agents, that the Security Trustee may incur in connection with (a)
the administration of this Agreement, (b) the creation, perfection or
continuation of the Security Interest or protection of its priority or the
Collateral, including the discharging of any prior or junior Lien or adverse
claim against the Collateral or any part thereof that is not permitted hereby or
by the Financing Documents, (c) the custody, preservation or sale of, collection
from, or other realization upon, any of the Collateral, (d) the exercise or
enforcement of any of the rights, powers or remedies of the Security Trustee
under this Agreement or under Applicable Law (including attorneys' fees and
expenses incurred by the Security Trustee in the collection of Collateral
deposited with the Security Trustee and amounts incurred in connection with the
operation, maintenance or foreclosure of the Security Interest) or any workout
or restructuring or insolvency or bankruptcy proceeding or (e) the failure by
any Pledgor to perform or observe any of the provisions hereof. All such amounts
and all other amounts payable hereunder shall be payable on demand, together
with interest at the Default Rate, from and including the due date to and
excluding the date of payment.

          Section 6.2. Amendments and Other Modifications. No amendment of any
provision of this Agreement (including a waiver thereof or consent relating
thereto) shall be effective unless the same shall be in writing and signed by
the Security Trustee. Any waiver or consent relating to any provision of this
Agreement shall be effective only in the specific instance and for the specific
purpose for which given. No notice to or demand on any Pledgor in any case shall
entitle such Pledgor to any other or further notice or demand in similar or
other circumstances.

          Section 6.3. Cumulative Remedies; Failure or Delay.

          The rights and remedies provided for under this Agreement are
cumulative and are not exclusive of any rights and remedies that may be
available to the Secured Parties under Applicable Law, the other Financing
Documents or otherwise. No failure or delay on the part of the Security Trustee
in the exercise of any power, right or remedy under this Agreement shall impair
such power, right or remedy or shall operate as a waiver thereof, nor shall any
single or partial exercise of any such power, right or remedy preclude other or
further exercise of such or any other power, right or remedy.

          Section 6.4. Notices, Etc. All notices and other communications under
this Agreement shall be in writing and shall be personally delivered or sent by
prepaid courier, by overnight, registered or certified mail (postage prepaid) or
by prepaid telex,

telecopy or telegram, and shall be deemed given when received by the intended
recipient thereof. Unless otherwise specified in a notice given in accordance
with the foregoing provisions of this Section 6.4, notices and other
communications shall be given to the parties hereto at their respective
addresses (or to their respective telex telecopier numbers) indicated on
Schedule 6.4.

          Section 6.5. Successors and Assigns. This Agreement shall be binding
upon and, subject to the next sentence, inure to the benefit of each Pledgor and
the Security Trustee and their respective successors and assigns. No Pledgor
shall assign or transfer any of its rights or obligations hereunder without the
prior written consent of the Security Trustee. The benefits of this Agreement
shall pass automatically with any assignment of the Secured Obligations (or any
portion thereof), to the extent of such assignment.

          Section 6.6. Payments Set Aside. Notwithstanding anything to the
contrary herein contained, this Agreement, the Secured Obligations and the
Security Interest shall continue to be effective or reinstated, as the case may
be, if at any time any payment, or any part thereof, of any or all of the
Secured Obligations is rescinded, invalidated, declared to be fraudulent or
preferential or otherwise required to be restored or returned by any Secured
Party in connection with any bankruptcy, reorganization or similar proceeding
involving any Pledgor, any other party liable with respect to the Secured
Obligations or otherwise, if the proceeds of any Collateral are required to be
returned by such Secured Party under any such circumstances, or if any Secured
Party elects to return any such payment or proceeds or any part thereof in its
sole discretion, all as though such payment had not been made or such proceeds
not been received. Without limiting the generality of the foregoing, if prior to
any such rescission, invalidation, declaration, restoration or return, this
Agreement shall have been cancelled or surrendered or the Security Interest or
any Collateral shall have been released or terminated in connection with such
cancellation or surrender, this Agreement and the Security Interest and such
Collateral shall be reinstated in full force and effect, and such prior
cancellation or surrender shall not diminish, discharge or otherwise affect the
obligations of the Pledgors in respect of the amount of the affected payment or
application of proceeds, the Security Interest or such Collateral.

          Section 6.7. Continuing Security Interest; Termination. This Agreement
shall create a continuing security interest in the Collateral and, except as
provided below, the Security Interest and all agreements, representations and
warranties made herein shall survive until, and this Agreement shall terminate
only upon, the indefeasible payment in full of the Secured Obligations.

          Notwithstanding anything in this Agreement or Applicable Law to the
contrary, the agreements of the Pledgors set forth in Sections 4.8.2 and 6.1
shall survive the payment of all other Secured Obligations and the termination
of this Agreement.

          Section 6.8. Choice of Forum

          6.8.1. Each of the Pledgors irrevocably agrees for the benefit of each
of the Beneficiaries 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 the other Financing
Documents) and, for such purposes, irrevocably submits to the jurisdiction of
such courts. Each of the Pledgors irrevocably agrees that the courts of the
State of New York and the courts of the United States of America in New York
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 the other Financing Documents) and, for such purposes,
irrevocably submits to the jurisdiction of such courts. Each of the Pledgors
irrevocably waives any objection which it might now or hereafter have to the
courts referred to in this Section 6.8.1 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 the Financing
Documents and agrees not to claim that any such court is not a convenient or
appropriate forum.

          IN ANY ACTION AGAINST ANY PLEDGOR, SERVICE OF PROCESS MAY BE MADE UPON
SUCH PLEDGOR OR BY DELIVERY OR BY REGISTERED OR CERTIFIED MAIL, RETURN RECEIPT
REQUESTED, TO ITS ADDRESS INDICATED IN SCHEDULE 6.4, WHICH SERVICE SHALL BE
DEEMED SUFFICIENT FOR PERSONAL JURISDICTION AND SHALL BE DEEMED EFFECTIVE UPON
RECEIPT, IN THE CASE OF DELIVERY, AND 10 DAYS AFTER MAILING, IN THE CASE OF
MAILING. Each Pledgor hereby irrevocably appoints CT Corporation Systems (the
"Process Agent"), with offices on the date hereof in New York, New York as
Process Agent to receive for and on behalf of such Pledgor service of process in
the County of New York relating to this Agreement. SERVICE OF PROCESS IN ANY
ACTION OR PROCEEDING AGAINST ANY PLEDGOR MAY BE MADE ON THE PROCESS AGENT BY
REGISTERED OR CERTIFIED MAIL, RETURN RECEIPT REQUESTED, OR BY ANY OTHER METHOD
OF SERVICE PROVIDED FOR UNDER APPLICABLE LAWS IN EFFECT IN THE STATE OF NEW
YORK, AND THE PROCESS AGENT IS HEREBY AUTHORIZED AND DIRECTED TO ACCEPT SUCH
SERVICE FOR AND ON BEAHLF OF SUCH PLEDGOR AND TO ADMIT SERVICE WITH RESPECT
THERETO. SUCH SERVICE UPON THE PROCESS AGENT SHALL BE DEEMED EFFECTIVE PERSONAL
SERVICE ON SUCH PLEDGOR, SUFFICIENT FOR PERSONAL JURISDICTION, 10 DAYS AFTER
MAILING, AND SHALL BE LEGAL AND BINDING UPON SUCH PLEDGOR FOR ALL PURPOSES,
NOTWITHSTANDING ANY FAILURE OF THE PROCESS AGENT TO MAIL COPIES OF SUCH LEGAL
PROCESS TO SUCH PLEDGOR, OR ANY FAILURE ON THE PART OF SUCH PLEDGOR TO RECEIVE
THE SAME. Each Pledgor confirms that it has instructed the Process Agent to mail
such Pledgor, upon service of process being made on the Process Agent pursuant
to this Section, a copy of the summons and complaint or other legal process
served upon it, be registered mail, return receipt

requested, at such Pledgor's address set forth in Schedule 6.4., or to such
other address as such Pledgor may notify the Process Agent in writing. Each
Pledgor agrees that it will at all time maintain a process agent to receive
service of process in the County of New York on its behalf with respect to this
Agreement. If for any reason the Process Agent or any successor thereto shall no
longer serve as such process agent or shall have changed its address without
notification thereof to the Beneficiaries, such Pledgor, immediately after
gaining knowledge thereof, irrevocably shall appoint a substitute process agent
acceptable to the Security Trustee in the County of New York and advise the
Security Trustee thereof.

          6.8.2. The submission to the jurisdiction of the courts referred to in
Section 6.8.1. shall not (and shall not be construed as to) limit the right of
the Beneficiaries or any of them to take proceedings against any of the Pledgors
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.

          Section 6.9. Waiver and Estoppel. Except as otherwise provided in this
Agreement, each Pledgor hereby waives: (a) presentment, protest, notice of
dishonor, release, compromise, settlement, extension or renewal and any other
notice of or with respect to the Secured Obligations and hereby ratifies and
confirms whatever the Security Trustee may do in this regard; (b) notice prior
to taking possession or control of any Collateral; (C) any bond or security that
might be required by any court prior to allowing the Security Trustee to
exercise any of their rights, powers or remedies; (d) the benefit of all
valuation, appraisement, redemption and exemption laws; (e) any rights to
require marshalling of the Collateral upon any sale or otherwise to direct the
order in which the Collateral shall be sold; (f) any set-off; and (g) any rights
to require the Security Trustee to proceed against any Person, proceed against
or exhaust any Collateral or any other security interests or guaranties or
pursue any other remedy in the Security Trustee power, or to pursue any of such
rights in particular order or manner, and any defenses arising by reason of any
disability or defense of any Person.

          Section 6.10. Nature of Agreement. This Agreement is independent of
and not in consideration of or contingent upon the liability of any Borrower or
any other Person and foreclosure or other action may be taken against all or any
Collateral and a separate action or actions may be brought and prosecuted
against any Pledgor, whether or not any foreclosure or other action is taken
with respect to any other collateral or action is brought or prosecuted against
any Borrower or any other obligor or whether any Borrower or any other obligor
is joined in any such action or actions. This Agreement shall be construed as
continuing, absolute and unconditional without regard to:

Agreement, the U.S. Loan Notes or any other Financing Document, any of the

Obligations, any Lien or other collateral or any guaranty of the Secured
Obligations or any part thereof;

          6.10.2. any defense (other than payment), set-off or counterclaim that

any right of setoff at any time held by, any Secured Party; or

          6.10.3. any other circumstance whatsoever (with or without notice to
or knowledge of any Pledgor or any other obligor), whether or not similar to any

equitable or legal discharge of any Borrower or any other obligor for the
Secured Obligations, in bankruptcy or in any other instance.

          Section 6.11. Authorization. Each Pledgor authorizes each Secured
Party, without notice to or further assent by such Pledgor, and without
affecting any Pledgor's liability hereunder or the Security Interest (regardless
of whether any subrogation or similar right that such Pledgor may have or any
other right or remedy of such Pledgor is extinguished or impaired), from time to
time to:

          6.11.1. permit any Borrower to increase or create Secured Obligations,
or terminate, release, compromise, subordinate, extend, accelerate or otherwise
change the amount or time, manner or place of payment of, or rescind any demand
for payment or acceleration of, the Secured Obligations or any part thereof
(including increasing or decreasing the rate of interest thereon), or otherwise
amend the terms and conditions of the Credit Agreement, the U.S. Loan Notes, any
other Financing Document or any provision thereof;

          6.11.2. take and hold other collateral from any Borrower or any other
Person, perfect or refrain from perfecting a Lien on such other collateral, and
exchange, enforce, subordinate, release (whether intentionally or
unintentionally), or take or fail to take any other action in respect of, any
such other collateral or Lien or any part thereof;

          6.11.3. exercise in such manner and order as it elects in its sole
discretion, fail to exercise, waive, suspend, terminate or suffer expiration of,
any of the remedies or rights of such Secured Party against any Borrower of any
other Person in respect of any Secured Obligations or any other collateral;

          6.11.4. release, add or settle with any Person in respect of this
Agreement, any guaranty or the Secured Obligations;

          6.11.5. accept partial payments on the Secured Obligations and apply
any and all payments or recoveries from any Person or other collateral to such
of the Secured Obligations as any Secured Party may elect in its sole
discretion, whether or not such Secured Obligations are otherwise secured or
guaranteed;

any payments or recoveries received by such Secured Party in respect of any
Secured Obligations or other collateral; and

          6.11.7. otherwise deal with any Borrower, any other obligor and any
other collateral as such Secured Party may elect in its sole discretion.

          Section 6.12. Execution in Counterparts. This Agreement may be

counterparts, taken together, shall constitute but one and the same Agreement.

consequential or punitive damages in respect of any claim for breach of contract
or under any other theory of liability arising out of or related to the
transactions contemplated by this Agreement and the other Financing Documents,
or any act, omission or event occurring in connection therewith; and each
Pledgor hereby waives, release and agrees not to sue upon any claim for any such
damages, whether or not accrued and whether or not known or suspected to exist
in its favor.

          Section 6.15. WAIVER OF TRIAL BY JURY. EACH PLEDGOR AND THE SECURITY
TRUSTEE WAIVE THE RIGHT TO A TRIAL BY JURY IN ANY ACTION UNDER THIS AGREEMENT OR
ANY OTHER FINANCING DOCUMENT OR ANY ACTION ARISING OUT OF THE TRANSACTIONS
CONTEMPLATED HEREBY OR THEREBY, REGARDLESS OF WHICH PARTY INITIATES SUCH ACTION

          passu with or after the security created by this Guarantee and

          Agreement or the US Loan Notes Instrument.

5.1  The Chargor hereby applies to the Chief Land Registrar for the registration
     against the registered titles specified in Schedule 2 of the following:

     (a)  a restriction in the following terms:

          interest is to be registered or noted without the consent of the
          proprietor for the time being of charge number [ ]";

<PAGE>


     (b)  a notice that under the provisions of this Guarantee and Debenture the
          Secured Parties are under an obligation to make further advances.

5.2  The Chargor shall from time to time and to the extent it is able to do so
     without breaching any provision of any other agreement binding upon it, at
     the request of the Security Trustee and at the Chargor's cost, execute in
     favour of the Security Trustee, or as it may direct, such further or other
     legal assignments, transfers, mortgages, charges or other documents as in
     any such case the Security Trustee shall stipulate over the Chargor's
     estate or interest in any property or assets of whatsoever nature or tenure
     and wheresoever situate, for the purpose of more effectively providing
     security to the Security Trustee on the terms of, or as intended to be
     created by, this Guarantee and Debenture for the payment or discharge of
     the Secured Obligations. Without prejudice to the generality of the
     foregoing, such assignments, transfers, mortgages, charges or other
     documents shall be in such form as the Security Trustee shall stipulate and
     may contain provisions such as are herein contained or provisions to the
     like effect and/or such other provisions of whatsoever kind as the Security
     Trustee shall consider requisite for the improvement or perfection of the
     security constituted by or pursuant to this Guarantee and Debenture. The
     obligations of the Chargor under this Clause shall be in addition to and
     not in substitution for the covenants for further assurance deemed to be
     included herein by virtue of the Law of Property (Miscellaneous Provisions)
     Act 1994.

5.3  The Chargor shall immediately after the execution of this Guarantee and
     Debenture (or upon becoming possessed thereof at any time hereafter)
     deposit with the Security Trustee all deeds, certificates and other
     documents constituting or evidencing title to its real property comprised
     within the Charged Property or any part thereof and to any of the assets
     and rights charged under Clause 3.1(e).

6.   DEBTS AND CREDIT BALANCES

6.1  With reference to the Debts the Chargor shall collect in the Debts and
     shall, in the absence of specific written instructions from the Security
     Trustee to the contrary, pay into the Chargor's current account with the
     Security Trustee and/or if so directed by the Security Trustee into a
     special or specifically designated account with the Security Trustee either
     in the name of the Chargor or the Security Trustee or into such other
     account as the Security Trustee may direct all moneys which the Chargor may
     receive in respect of the Debts and shall not without the prior consent in
     writing of the Security Trustee sell, factor, discount or otherwise charge
     or assign the Debts in favour of any other person or purport to do so and
     the Chargor shall if called upon to do so by the Security Trustee from time
     to time execute legal assignments of the Debts to the Security Trustee in
     forms approved by the Security Trustee.

6.2  Prior to the security hereby created becoming enforceable, in the absence
     of any written directions to the contrary from the Security Trustee to pay
     such moneys into any other account, any moneys in respect of the Debts
     received by the Chargor and paid into any current account with the Security
     Trustee in accordance with the

<PAGE>


     requirements of Clause 6.1 hereof shall upon being paid into such current
     account be released from the fixed charge created by Clause 3.1(d) hereof
     and shall become subject to the floating charge created by Clause 3.1(i) .
     Such release from the fixed charge shall not affect and shall be entirely
     without prejudice to the continuance of the said fixed charge on all other
     Debts of the Chargor outstanding from time to time and on all moneys which
     the Chargor receives in respect thereof.

6.3  With reference to the Credit Balances the Chargor agrees to inform the
     Security Trustee as soon as any Credit Balance with any third party comes
     into existence and if so directed by the Security Trustee the Chargor shall
     transfer any such Credit Balance into the Chargor's account with the
     Security Trustee or into a specifically designated account with the
     Security Trustee in the name of the Chargor or the Security Trustee or in
     the joint names of the Chargor and the Security Trustee and shall not
     without the prior consent in writing of the Security Trustee sell or
     otherwise charge or assign any Credit Balance in favour of any person or
     purport to do so.

7.   CONVERSION OF FLOATING CHARGE AND AUTOMATIC CRYSTALLISATION

7.1  If, at any time, the Security Trustee believes that any assets of the
     Chargor are in danger of being seized or sold under any form of distress,
     execution or other similar process then without prejudice to the provisions
     of Clause 7.2 the Security Trustee may, by notice in writing to the
     Chargor, convert the floating charge created by this Guarantee and
     Debenture into a fixed charge in relation to the assets specified in such
     notice (which assets need not be exclusively those assets which are in
     danger of seizure or sale) and the Security Trustee shall further be
     entitled (but not bound) to take possession of or appoint a Receiver of
     such assets.

7.2  If the Chargor charges, pledges or otherwise encumbers (whether by way of
     fixed or floating security) any of the property, assets and income
     comprising the Floating Charge Property or attempts so to do without the
     prior consent in writing of the Security Trustee or if any creditor or
     other person levies any distress, execution, sequestration or other process
     against any of the said property, assets and income then in the absence of
     any notice or other action by the Security Trustee pursuant to Clause 7.1
     the floating charge hereby created shall automatically operate as a fixed
     charge forthwith upon the occurrence of such event, but only in respect of
     the assets, property or income in respect of which or against which such
     action was taken.

8.   INSURANCE

8.1  The Chargor shall at all times during the subsistence of the security
     constituted by or pursuant to this Guarantee and Debenture comply with all
     covenants, undertakings and conditions as to insurance of any part of the
     Charged Property imposed by the terms of any lease, agreement for lease or
     any tenancy under which the Chargor

     derives its estate or interest therein and, subject to the foregoing and so
     far as not inconsistent with the said terms, the Chargor shall at all such
     times:

     (a)  cause all buildings, trade and other fixtures and all plant,
          machinery, vehicles, computers and office and other equipment and all
          stock in trade forming part of the Charged Property to be insured and
          to be kept insured in such insurance office, in such amounts and
          against such risks as the Security Trustee may require from time to
          time, but otherwise in such insurance office of repute as shall have
          been selected by the Chargor or with Lloyd's underwriters on the
          equivalent basis as insurances are maintained by prudent companies
          carrying on businesses comparable with that of the Chargor and on a
          comparable scale as regards the property and assets insured, the
          insured risks and the classes of risk to be covered and the amount of
          the insurance cover;

     (b)  cause the interest of the Security Trustee and the other Secured
          Parties in all parts of the Charged Property that are for the time
          being insured otherwise than in the joint names of the Security
          Trustee and the Chargor to be noted by endorsement on the policy or
          policies of insurance relating thereto;

     (c)  duly and punctually pay all premiums and other moneys due and payable
          under all such insurances as aforesaid and promptly upon request by
          the Security Trustee produce to the Security Trustee the premium
          receipts or other evidence of the payment thereof; and

     (d)  on demand by the Security Trustee, deposit all policies and other
          contracts of insurance relating to the Charged Property or any part
          thereof with the Security Trustee or produce the same to the Security
          Trustee for inspection.

8.2  If default shall be made by the Chargor in complying with Clause 8.1 the
     Security Trustee may but shall not be obliged to effect or renew any such
     insurance as is mentioned in that Clause either in its own name or in its
     name and that of the Chargor jointly or in the name of the Chargor with an
     endorsement of the Security Trustee's interest. The moneys expended by the
     Security Trustee on so effecting or renewing any such insurance shall be
     reimbursed by the Chargor to the Security Trustee on demand and until so
     reimbursed shall carry interest at the rate of two (2) per cent. above the
     Security Trustee's Rate from time to time from the date of payment to the
     date of reimbursement (after as well as before any judgment).

8.3  All claims and moneys received or receivable under any such insurances as
     aforesaid shall (subject to the rights and claims of any lessor or landlord
     of any part of the Charged Property) at the direction of the Security
     Trustee be applied in making good the loss or damage in respect of which
     the same has been received or in or towards the discharge of the Secured
     Obligations.

9.   UNDERTAKINGS BY THE CHARGOR

<PAGE>


9.1  The Chargor hereby undertakes with the Security Trustee and the Secured
     Parties that it will at all times while there shall subsist any security
     constituted by or pursuant to this Guarantee and Debenture:

     (a)  keep all buildings, trade and other fixtures, fixed and other plant
          and machinery forming part of the Charged Property in good and
          substantial repair and permit the Security Trustee, its officers,
          employees and agents free access at all reasonable times to view the
          state and condition thereof, provided that the Security Trustee shall

          exercise its rights under this sub-Clause and requested access
          accordingly;

     (b)  preserve, maintain and renew as and when necessary all copyrights,

          with its business:

     (c)  observe and perform all covenants and stipulations from time to time
          affecting its freehold or leasehold property or the mode of user or
          enjoyment of the same and not without the prior consent in writing of
          the Security Trustee enter into any onerous or restrictive obligations
          affecting any such property or make any structural or material
          alteration thereto or do or suffer to be done on any such property
          anything which is "development" as defined in section 55 of the Town
          and Country Planning Act 1990 nor do or suffer or omit to be done any
          act, matter or thing whereby any provision of any Act of Parliament,
          order or regulation from time to time in force affecting any such
          property is infringed;

     (d)  observe and perform all covenants reserved by or contained in any
          lease, agreement for lease or tenancy agreement under which any part
          of the Charged Property may be held and will not, without the consent

          dispose of or permit to be forfeited any leasehold interest forming
          part of the Charged Property or agree any rent review;

     (e)  not without the prior consent of the Security Trustee part with
          possession of the whole or any part of, or confer on any other person
          any right or licence to occupy, or grant any licence to assign or
          sub-let land or buildings forming part of the Charged Property;

     (f)  not without the prior written consent of the Security Trustee allow
          any person other than itself to be registered under the Land
          Registration Act 1925 as proprietor of the Charged Property or any
          part thereof or create or permit to arise any overriding interest (as
          specified in section 70(1) of the Land Registration Act 1925)
          affecting such property and the reasonable costs incurred by the
          Security Trustee of lodging a caution against registration of the
          title to such property or a land charge (if unregistered) or any part
          thereof, shall be an expense properly incurred in relation to this
          security; and

<PAGE>


     (g)  indemnify the Security Trustee (and as a separate covenant any
          Receiver or Receivers appointed by it) against all existing and future
          rents, taxes, rates, duties, fees, renewal fees, charges, assessments,
          impositions and outgoings whatsoever (whether imposed by deed or
          statute or otherwise and whether in the nature of capital or revenue
          and even though of a wholly novel character) which now or at any time
          during the continuance of the security constituted by or pursuant to
          this Guarantee and Debenture are properly payable in respect of the
          Charged Property or any part thereof or by the owner or occupier
          thereof.

9.2  If any such sums as are referred to in Clause 9.1(g) shall be paid by the
     Security Trustee (or any Receiver or Receivers) the same shall be
     reimbursed by the Chargor to the Security Trustee on demand and until so
     reimbursed shall bear interest at the rate of two (2) per cent. above the
     Security Trustee's Rate from time to time from the date of payment to the
     date of reimbursement (after as well as before any judgment).

10.  POWERS OF THE SECURITY TRUSTEE

10.1 At any time after the making of a Demand, or if requested by the Chargor,
     the Security Trustee may exercise without further notice and without any of
     the restrictions contained in section 103 of the Law of Property Act 1925,
     whether or not it shall have appointed a Receiver, all the powers conferred
     on mortgagees by the Law of Property Act 1925 and all the powers and
     discretions conferred by this Guarantee and Debenture.

10.2 The statutory powers of leasing, letting, entering into agreements for
     leases or lettings and accepting and agreeing to accept surrenders of
     leases conferred by sections 99 and 100 of the said Act shall not be
     exercisable by the Chargor in relation to any part of the Charged Property
     without the prior written consent of the Security Trustee. In addition to
     such statutory powers the Security Trustee shall have power after serving
     the notice referred to in Clause 10.1 to lease or make agreements for
     leases at a premium or otherwise and accept surrenders of leases and
     generally without any restriction on the kinds of leases and agreements for
     leases that the Security Trustee may make and generally without the
     necessity for the Security Trustee to comply with any restrictions imposed
     by or the other provisions of the said sections 99 and 100. The Security
     Trustee may delegate such powers to any person and no such delegation shall
     preclude the subsequent exercise or such powers by the Security Trustee
     itself or preclude the Security Trustee from making a subsequent delegation
     thereof to some other person and any such delegation may be revoked.

10.3 The restriction on the right of consolidating mortgage securities contained
     in section 93 of the Law of Property Act 1925 shall not apply to this
     Guarantee and Debenture.

<PAGE>


10.4 So far as permitted by law, neither the Security Trustee nor any Receiver
     shall by reason of it or any Receiver entering into possession of any part
     of the Charged Property when entitled so to do be liable to account as
     mortgagee in possession or be liable for any loss or realisation or for any
     default or omission for which a mortgagee in possession might be liable.

11.  APPOINTMENT OF RECEIVER

11.1 At any time after the making of a Demand, or if requested by the Chargor or

     appoint one or more persons to be a Receiver or Receivers of the Charged
     Property or any part thereof.

11.2 Subject to Section 45 of the Insolvency Act 1986, the Security Trustee may
     remove any Receiver previously appointed hereunder, and appoint another
     person or other persons as Receiver or Receivers, either in the place of a
     Receiver so removed or who has otherwise ceased to act or to act jointly
     with a Receiver or Receivers previously appointed hereunder.

11.3 If at any time and by virtue of any such appointment(s) any two or more
     persons shall hold office as Receivers of the same assets or income, each
     one of such Receivers shall be entitled (unless the contrary shall be
     stated in any of the deed(s) or other instrument(s) appointing them) to
     exercise all the powers and discretions hereby conferred on Receivers
     individually and to the exclusion of the other or others of them.

11.4 Every such appointment or removal, and every delegation, appointment or
     removal by the Security Trustee in the exercise of any right to delegate
     its powers or to remove delegates herein contained, may be made in writing
     under the hand of any officer of the Security Trustee.

11.5 Every Receiver shall have:

     (a)  all the powers conferred by the Law of Property Act 1925 on mortgagees
          in possession and receivers appointed under that Act:

     (b)  all the powers specified in Schedule1of the Insolvency Act 1986; and

     (c)  all the powers of the Security Trustee hereunder.

11.6 In making any sale or other disposal of any of the Charged Property in the
     exercise of their respective powers, the Receiver or the Security Trustee
     may accept, as and by way of consideration for such sale or other disposal,
     cash, shares, loan capital or other obligations, including without
     limitation consideration fluctuating according to or dependent upon profit
     or turnover and consideration the amount whereof is to be determined by a
     third party. Any such consideration may be receivable in a lump sum or by
     instalments.

<PAGE>


11.7 All moneys received by any Receiver appointed under this Guarantee and
     Debenture shall be applied in the following order: (1) in the payment or
     the costs, charges and expenses of and incidental to the Receiver's
     appointment and the payment of his remuneration; (2) in the payment and
     discharge of any outgoings paid and liabilities incurred by the Receiver in
     the exercise of any of the powers of the Receiver; (3) in providing for the
     matters (other than the remuneration of the Receiver) specified in the
     first three paragraphs of Section 109(8) of the Law of Property Act 1925;
     (4) in or towards payment of any debts or claims which are required by law
     to be paid in preference to the Secured Obligations but only to the extent
     to which such debts or claims have such preference; (5) in or towards the
     satisfaction of the Secured Obligations in accordance with the terms of the
     Intercreditor Agreement, and (6) any surplus shall be paid to the Chargor
     or other person entitled thereto. The provisions of this Clause and Clause
     11.9 shall take effect as and by way of variation and extension to the
     provisions of the said Section 109(8), which provisions as so varied and
     extended shall be deemed incorporated herein.

11.8 Every Receiver shall be the agent of the Chargor which shall be solely
     responsible for his acts and defaults and for the payment of his
     remuneration.

11.9 Every Receiver shall be entitled to remuneration for his services at a rate
     to be fixed by agreement between him and the Security Trustee (or, failing
     such agreement, to be conclusively fixed by the Security Trustee)
     commensurate with the work and responsibilities involved upon the basis of
     charging from time to time adopted in accordance with his current practice
     or the current practice of his firm and without being limited to the
     maximum rate specified in section 109(6) of the Law of Property Act 1925.

          this Clause; and

     (c)  any Receiver appointed hereunder and for the time being holding office
          as such;

     statutory covenant referred to in such Clause) and, following the making of
     a Demand, for carrying any sale, lease or other dealing by the Security
     Trustee or such Receiver into effect, for conveying or transferring

<PAGE>

     any legal estate or other interest in land or other property or otherwise
     howsoever, for getting in the Charged Property, and generally for enabling
     the Security Trustee and the Receiver to exercise the respective powers
     conferred on them by or pursuant to this Guarantee and Debenture or by law.
     The Security Trustee shall have full power to delegate the power conferred
     on it by this Clause, but no such delegation shall preclude the subsequent
     exercise of such power by the Security Trustee itself or preclude the
     Security Trustee from making a subsequent delegation thereof to some other
     person; any such delegation may be revoked by the Security Trustee at any
     time.

12.2 The power of attorney hereby granted is as regards the Security Trustee,
     its delegates and any such Receiver (and as the Chargor hereby
     acknowledges) granted irrevocably and for value as part of the security
     constituted by this Guarantee and Debenture to secure proprietary interests
     in and the performance of obligations owed to the respective donees within

13.  PROTECTION OF PURCHASERS

     No purchaser or other person dealing with the Security Trustee or its
     delegate or any Receiver appointed hereunder shall be bound to see or
     enquire whether the right of the Security Trustee or such Receiver to

     concerned to see whether any such delegation by the Security Trustee shall
     have lapsed for any reason or been revoked.

     In addition to any general lien or similar rights to which they may be
     entitled by operation of law, each of the Secured Parties shall have the

     such Secured Parties on any other account or in any other respect. The
     liabilities referred to in this Clause may be actual, contingent, primary,
     collateral, several or joint liabilities, and the accounts, sums and
     liabilities referred to in this Clause may be denominated in any currency.

     Clause) from their existing currency of denomination into any other

     subsequent charge or other interest affecting any part of the Charged

     Parties may open a new account or accounts with the Chargor. If any of the
     Secured Parties do not open a new account or accounts they shall
     nevertheless be treated as if they had done so at the time when the notice
     was, or was deemed to be, received and as from that time all payments made
     to the Secured Parties shall be credited or be treated as having been
     credited to the new account or accounts and shall not operate to reduce the

     received or was deemed to have received such notice.

19.  CONTINUING SECURITY

     continuing and shall not be considered as satisfied or discharged by any
     intermediate payment or settlement of the whole or any part of the Secured
     Obligations and shall be binding until all the Secured Obligations have
     been discharged in full to the satisfaction of the Security Trustee and all
     of the Secured Parties have ceased to have any obligation whether actual or
     contingent to make any credit or accommodation available to any company
     within the Group under or pursuant to the Financing Documents.

20.  REMEDIES CUMULATIVE ETC.

20.1 The rights, powers and remedies provided in this Guarantee and Debenture
     are cumulative and are not, nor are they to be construed as, exclusive of
     any rights, powers or remedies provided by law or otherwise.

20.2 No failure on the part of the Security Trustee to exercise, or delay on its
     part in exercising, any of its respective rights, powers and remedies
     provided by this Guarantee and Debenture or by law (collectively the

     partial waiver of any of the Rights preclude any further or other exercise
     of that one of the Rights concerned or the exercise of any other of the
     Rights.

20.3 The Chargor hereby agrees to indemnify the Security Trustee, the Secured
     Parties and any Receiver against all losses, actions, claims, costs,
     charges, expenses and liabilities incurred by the Security Trustee, the
     Secured Parties and by any Receiver (including any substitute delegate
     attorney as aforesaid) in relation to this Guarantee and Debenture or the
     Secured Obligations (including, without limitation, the costs, charges and
     expenses incurred in the carrying of this Guarantee and Debenture into
     effect or in the exercise of any of the rights, remedies and powers
     conferred hereby or in the perfection or enforcement of the security
     constituted hereby or pursuant

     hereto or in the perfection or enforcement of any other security for or
     guarantee in respect of the Secured Obligations) or occasioned by any
     breach by the Chargor of any of its covenants or obligations under this
     Guarantee and Debenture. The Chargor shall so indemnify the Security
     Trustee, the Secured Parties and any Receiver on demand and shall pay
     interest on the sum demanded at the rate per annum of two (2) per cent.
     above the Security Trustee's Rate from time to time from the date on which
     the same were demanded by the Security Trustee, any Secured Parties or any
     Receiver, as the case may be, and any sum so demanded together with any
     interest, shall be a charge upon the Charged Property in addition to the
     moneys hereby secured.

21.  PROVISIONS SEVERABLE

     Every provision contained in this Guarantee and Debenture shall be
     severable and distinct from every other such provision and if at any time
     any one or more of such provisions is or becomes invalid, illegal or
     unenforceable, the validity, legality and enforceability of the remaining
     such provisions shall not in any way be affected thereby.

22.  THE SECURITY TRUSTEE'S DISCRETION

22.1 Save where expressly stated to the contrary herein, any liberty or power
     which may be exercised or any determination which may be made hereunder by
     the Security Trustee may be exercised or made in the absolute and
     unfettered discretion of the Security Trustee which shall not be under any
     obligation to give reasons therefor.

22.2 A certificate by an officer of the Security Trustee as to any sums payable
     to the Security Trustee hereunder shall, save in the case of manifest
     error, be conclusive and binding.

     The Security Trustee shall hold the benefit of the covenants, mortgages and
     charges given by the Chargor hereto upon trust for the Secured Parties.

     effect until all moneys, obligations and liabilities referred to in Clause
     2 of this Guarantee and Debenture have been paid, discharged or satisfied

     whatever the Security Trustee and any of the other Secured Parties may
     continue any accounts of any company within the Group or open one or more
     new accounts and the liability of the Chargor hereunder shall not in any
     manner be reduced or affected by any subsequent transactions or receipts or
     payments into or out of any such accounts.

1.4  If any purported obligation or liability of any company within the Group to
     any of the Secured Parties which if valid would have been the subject of
     this Guarantee is not or ceases to be valid or enforceable against any
     company within the Group on any ground whatsoever whether or not known to
     the Secured Parties including but not limited to any defect in or want of
     powers of any company within the Group or irregular exercise thereof or
     lack of authority by any person purporting to act on behalf of any company
     within the Group or any legal or other limitation (whether under the
     Limitation Acts or otherwise), disability, incapacity or any change in the
     constitution of or any amalgamation, reconstruction or liquidation of any
     company within the Group, the Chargor shall nevertheless be liable to the
     Secured parties in respect of that purported obligation or liability as if
     the same were fully valid and enforceable and the Chargor was the principal
     debtor in respect thereof. The Chargor hereby agrees to keep the Secured
     Parties fully indemnified against all damages, loss, costs and expenses
     arising from any failure of any company within the Group to carry out any
     such purported obligation or liability.

1.5  The liability of the Chargor shall not be affected nor shall this Guarantee
     and Debenture be discharged or diminished by reason of:

     (a)  any present or future bill, note guarantee, indemnity, mortgage,
          charge, pledge, lien or other security or right or remedy held by or
          available to the Secured Parties becoming wholly or in part void,
          voidable or unenforceable on any ground whatsoever or by the Secured
          Parties from

<PAGE>


          time to time dealing with, exchanging, varying, realising, releasing
          or failing to perfect or enforce any of the same; or

     (b)  the Secured parties compounding with, discharging, releasing or
          varying the liability of or granting any time, indulgence or
          concession to any company within the Group or any other person or
          renewing, determining, varying or increasing any bill, promissory note
          or other negotiable instrument, accommodation, facility or transaction
          in any manner whatsoever or concurring in, accepting or varying any
          compromise, arrangement or settlement or omitting to claim or enforce
          payment from any company within the Group or any other person; or

     (c)  any act or omission which would have discharged or affected the
          liability of the Chargor had it been principal debtor instead of
          guarantor or by anything done or omitted which bur for this provision
          might operate to exonerate the Chargor.

1.6  The Chargor warrants to the Secured Parties that it has not taken or
     received and undertakes that it will not take or receive the benefit of any
     security from any company within the Group in connection with this
     Guarantee and Debenture. If any such security is taken the Chargor hereby
     declares that such security and all moneys at any time received in respect
     thereof shall be held on trust for the Secured Parties and as security for
     the liabilities of the Chargor under this Guarantee.

1.7  The Chargor hereby agrees to pay interest to the Security Trustee for the
     account of the Secured Parties on all sums demanded under this Guarantee
     and Debenture from the date of demand until actual payment (as well after
     as before any judgment) at the rate of two (2) per cent. above the Security
     Trustee's Rate calculated on a day to day basis. Such interest shall be
     compounded monthly in accordance with the usual practice of the Security
     Trustee but without prejudice to the right of the Security Trustee to
     require payment of such interest.

1.8  Until the Secured Obligations have been paid, discharged or satisfied in
     full, the Chargor hereby waives all rights of subrogation and indemnity
     against any company within the Group and agrees not to share in any
     security held or moneys received by the Security Trustee or any other
     Secured Party on account of the Secured Obligations or (unless so
     instructed by the Security Trustee) to claim or prove in competition with
     the Secured Parties in the liquidation of any company within the Group in
     respect of any moneys paid by the Chargor to the Security Trustee or any
     other Secured Party under this Guarantee and Debenture. If the Chargor
     receives any payment or other benefit or exercises any set-off or
     counter-claim or otherwise acts in breach of this Clause anything so
     received and any benefit derived directly or indirectly by the Chargor
     therefrom shall be held in trust for the Secured Parties and as security
     for the liabilities of the Chargor under this Guarantee and Debenture.

1.9  Any money received in connection with this Guarantee and Debenture may be
     placed to the credit of a suspense account with a view to preserving the
     right of each of the Secured Parties to prove for the whole of its claim
     against any company within the Group or any other person liable or may be
     applied by the Secured Parties

<PAGE>


     in or towards satisfaction of such of the moneys, obligations or
     liabilities of the Chargor under this Guarantee and Debenture as the
     Security Trustee may from time to time conclusively determine.

1.10 Any release, discharge or settlement between the Chargor and the Security
     Trustee shall be conditional upon no security disposition or payment to the
     Secured Parties by any company within the Group or any other person being
     void, set aside or ordered to be refunded pursuant to any enactment or law
     relating to bankruptcy, liquidation or insolvency or for any reason
     whatever and if such condition shall not be fulfilled the Security Trustee
     shall be entitled to enforce this Guarantee and Debenture subsequently as
     if such release, discharge or settlement had not occurred and any such
     payment had not been made.

1.11 Unless and until the Secured Parties are satisfied in their absolute
     discretion as to the solvency of the Chargor the Secured Parties shall be
     entitled to retain any security constituted by or pursuant to Clause 3 of
     this Guarantee and Debenture for a period of up to six months after the
     payment, discharge or satisfaction of all moneys, obligations and
     liabilities that are or may become due, owing or incurred to or in favour
     of the Secured Parties from each company within the Group or the Chargor
     and notwithstanding any such payment, discharge or satisfaction, in the
     event of an act of bankruptcy by or the commencement of winding-up of the
     person making such payment or effecting such discharge or satisfaction at
     any time within the said period of six months, the Security Trustee shall
     be entitled to retain any such security for such further period as the
     Security Trustee may determine.

1.12 If this Guarantee is determined or called in by demand made by the Security
     Trustee, then the Secured Parties may open a new account or accounts with
     any or all companies within the Group; if the Secured Parties do not open a
     new account or accounts they shall nevertheless be treated as if they had
     done so at the time of determination or calling in and as from that time
     all payments made to the Secured Parties shall be credited or be treated as
     having been credited to the new account or accounts and shall not operate
     to reduce the amount for which this Guarantee is available as security at
     that time.

1.13 The Security Trustee shall not be obliged before taking steps to enforce
     this Guarantee:

     (a)  to take action or obtain judgment in any court against any company
          within the Group or any other person; or

     (b)  to make or file any claim in a bankruptcy or liquidation of any
          company within the Group or any other person; or

     (c)  to make, enforce or seek to enforce any claim against any company
          within the Group or any other person under any security or other
          document, agreement or arrangement.

1.14 All sums due and payable by the Chargor under this Guarantee and Debenture
     shall be made in full without set-off or counter-claim and free and clear
     of and (subject as

<PAGE>

     provided in the next sentence) without deduction for or on account of any
     future or present Taxes. If:

     (a)  the Chargor is required by any law to make any deduction or
          withholding from any sum payable by the Chargor to the Security
          Trustee hereunder; or

     (b)  the Security Trustee or any other Secured Party is required by law to
          make any payment on account of tax (other than tax on its overall net
          income) or otherwise, on or in relation to any amount received or
          receivable by the Secured Parties hereunder;

     then the sum payable by the Chargor in respect of which such deduction,
     withholding or payment is required to be made shall be increased to the
     extent necessary to ensure that, after the making of such deduction,
     withholding or payment, (and after taking account of any deduction,
     withholding or payment which is required to be made as a result of the
     increase) the Security Trustee receives and retains a net sum equal to the
     sum which it and the other Secured Parties would have received and so
     retained had no such deduction, withholding or payment been made.

1.15 This Guarantee and Debenture is and will remain the property of the
     Security Trustee.

                                FIRST AMENDMENT

      FIRST AMENDMENT, dated as of December 21, 1995 (the "First Amendment) by
and between AUTOMATED SECURITY (HOLDINGS) PLC, a limited company incorporated
under the laws of England and Wales (herein called the "Company") and THE
PRUDENTIAL INSURANCE COMPANY OF AMERICA (the "Noteholder") as the sole holder of
notes issued by the Company under a Note Agreement, dated as of May 27, 1994
(herein called the Company under a Note Agreement, dated as of May 27, 1994
(herein called the "Note Agreement") between the Company and the Noteholder.
Capitalized terms used herein and not otherwise defined herein shall have the
respective meanings set forth in the Amended Note Agreement (as hereinafter
defined).

                              W I T N E S S E T H :

Agreement;

      NOW, THEREFORE, in consideration thereof, the Company and the Noteholder
agree as follows:

      1. Amendment of Note Agreement. The Company and the Noteholder hereby
agree that effective as of the date (the "Effective Date") on which the
Noteholder shall have executed and delivered the notice attached hereto as
Exhibit A (the "Effective Date Notice"), without any other further action, the
Note Agreement shall be considered amended and restated as provided in Exhibit B
hereto. The Note Agreement as amended and restated in accordance with this
Agreement is herein referred to as the Amended Note Agreement.

received from White & Case, who are acting as special counsel for the Noteholder
in connection with this First Amendment, a favorable opinion satisfactory to the
Noteholder as to such matters incident to the matters herein contemplated as the
Noteholder may reasonably request. Such opinion shall also state that, based
upon such investigation and inquiry as is deemed relevant and appropriate by
such counsel, the opinion referred to in paragraph 2B is satisfactory in form
and scope to such counsel and, while such investigation and inquiry into the
matters covered by such opinion (other than to certain specified matters) were
not sufficient to enable such counsel independently to render such opinion,
nothing has come to the attention of such counsel which has caused it to
question the legal conclusions expressed in the opinion referred to in


<PAGE>

paragraph 2B and such counsel believes that the Noteholder is justified in
relying on such opinion.

      2B. Opinion of Company's Counsel. The Noteholder shall have received from
(i) O'Sullivan Graev & Karabell, LLP-special United States counsel for the
Company and (ii) Clifford Chance, special English counsel for the Company,

warranties contained in paragraph 8 of the Amended Note Agreement shall be true
on and as of the Effective Date; there shall exist on the Effective Date no
Event of Default or Default; and the Company shall have delivered to the
Noteholder an Officer's Certificate, dated the Effective Date, to both such
effects.

The Prudential Insurance Company
      of America
Four Gateway Center
100 Mulberry Street
Newark, New Jersey 07102-4069
U.S.A.

Ladies and Gentlemen:

      The undersigned, Automated Security (Holdings) PLC (the "Company"), hereby
agrees with you (the "Purchaser") as follows:

      1. [intentionally omitted]

      2. [intentionally omitted]

      3. [intentionally omitted]

      4. PREPAYMENTS OF NOTES.

      4A. Mandatory Prepayment of Notes. The Company shall repay the outstanding
principal amount of the Notes, together with all interest accrued but unpaid
thereon, on the Final Maturity Date.

      4B. Optional Prepayment of Notes With Yield-Maintenance Amount. The Notes
shall be subject to prepayment, in whole at any time or from time to time in
part (in multiples of $1,000,000 except for prepayments arising in accordance
with paragraph 6G or 6H), at the option of the Company (or as provided below in
connection with paragraphs 6G and 6H, at the option of the Noteholders, at 100%
of the principal amount so prepaid plus interest of the Noteholders), at 100% of
the principal amount so prepaid plus interest thereon to the prepayment date and
the Yield-Maintenance Amount, if any, with respect to each Note. The Company
shall give the holder of each Note irrevocable written notice of any prepayment
pursuant to this paragraph 4B not less than 30 Business Days nor more than 60
Business Days prior to the prepayment date, specifying such prepayment date and
the principal amount of the Notes, and of the Notes held by such holder, to be
prepaid on such date and


<PAGE>

stating that such prepayment is to be made pursuant to this paragraph 4B;
provided that in the case of a prepayment arising in accordance with paragraph
6G and 6H, notice of such prepayment shall be given no less than 5 Business Days
prior to the prepayment date and the prepayment date shall occur no later than 5
Business Days after the event giving rise to the obligation to prepay the Notes
in accordance with paragraph 6G and 6H. Notice of prepayment having been given
as aforesaid, the principal amount of the Notes specified in such notice,
together with interest thereon to the prepayment date and together with the
Yield-Maintenance Amount, if any, shall become due and payable on such
prepayment date; provided that in the case of a prepayment arising in accordance
with paragraph 6G and 6H, the Notes held by any Noteholder shall not be prepaid
if such Noteholder shall inform the Company at least 2 Business Days prior the
prepayment date that such Noteholder elects not to have its Notes prepaid.
Promptly after the Yield-Maintenance Amount, if any, can be calculated with
respect to the Notes to be prepaid, the Company shall notify each of the
Noteholders by facsimile (with confirmation in writing by overnight courier) of
the amount thereof payable to such Noteholder, showing the Company's computation
thereof in reasonable detail.

      4C. Partial Payments Pro Rata. (a) Upon any partial prepayment of the
Notes pursuant to paragraph 4B, the principal amount so prepaid shall be
allocated among the Notes (including, for the purpose of this paragraph 4C only,
all Notes purchased or otherwise acquired and held by the Company or any other
member of the Group of Affiliates) in proportion to the respective outstanding
principal amounts thereof; provided, however, in respect of any prepayment
obligation arising under paragraph 6G and 6H, if any Noteholder elects not to
accept prepayment of its Notes, then the partial prepayment shall be made pro
rata among the remaining Noteholders who have not so elected.

      (b) Upon any prepayment of Notes pursuant to paragraph 6G and 6H, the
amounts distributed to Noteholders in accordance with Sharing Proportions shall
be applied by each Noteholder receiving such proceeds in the following order of
application:

            (i) first, against the amount of any success fee, if any payable to
      such Noteholder in accordance with paragraph 3 of the First Amendment;

            (i) second, against any unpaid but accrued interest to the date of
      prepayment on the principal amount of the Notes held by such Noteholder
      prepaid under clause (iv) below;

            (iii) third, against Yield-Maintenance Amounts, if any, due to such
      Noteholder in relation to the principal amount of the Notes being prepaid
      under clause (iv) below;

            (iv) fourth, against the principal amount of the Notes held by such
      Noteholder; and

                                        2

<PAGE>



            (v) fifth, as such Noteholder shall determine.

      4D. Retirement of Notes. The Company shall not, and shall not permit any
of its Subsidiaries or Affiliates to, prepay or otherwise retire in whole or in
part prior to their stated final maturity (other than as provided in paragraph
4A or by prepayment pursuant to paragraph 4B, 4E or 4F or upon acceleration of
such final maturity pursuant to paragraph 7A), or purchase or otherwise acquire,
directly or indirectly, Notes held by any holder unless the Company or such
Subsidiary or Affiliate shall have offered to prepay or otherwise retire or
purchase or acquire, as the case may be, the same proportion of the aggregate
principal amount of the Notes held by each other holder of the Notes at the time
outstanding upon the same terms and conditions. Any Notes so prepaid or
otherwise retired or purchased or otherwise acquired by the Company or any of
its Subsidiaries or Affiliates shall not be deemed to be outstanding for any
purpose under this Agreement except as provided in paragraph 4C.

      4E. Redemption for Taxation Reasons. (a) If the company would, on the
occasion of the next payment in respect of the Notes, be required to pay an
Additional Payment as a result of a Special Tax Event (as defined below) which
exceeds, in the aggregate, 10% of the aggregate amount of the interest payment
then due and payable on account of such Notes, and after using reasonable
efforts the Company is unable to avoid the circumstances which necessitates the
payment of such Additional Payment, then the Company shall be entitled to
exercise its rights under this paragraph 4E to prepay all outstanding Notes with
respect to which the Company will be required to make an Additional Payment in
accordance with paragraph 4E(b) below.

      (b) The company shall give the holder of each Note with respect to which
the Company would, on the occasion of the next payment in respect of the Notes,
be required to make an Additional Payment and which it wishes to redeem pursuant
to this paragraph 4E(b) irrevocable written notice of any prepayment pursuant to
this paragraph 4E(b) not less than 30 days (nor more than 60 days) prior to the
prepayment date, specifying (i) the amount of the Notes, and the Notes held by
the Noteholder, that are to be prepaid pursuant to this paragraph 4E(b), (ii)
the circumstances that would necessitate the payment of an Additional Payment,
the amount of such Additional Payment and the steps taken by the Company to
avoid the necessity of making such payment (the Company hereby agrees to take
reasonable steps in attempting to avoid the necessity of making such prepayment)
and (iii) the required prepayment date, which shall be a Business Day. Notice of
prepayment having been given as aforesaid, the principal amount of the Notes to
be prepaid pursuant to this paragraph 4E(b), together with interest thereon to
the prepayment date and together with the Modified Yield-Maintenance Amount, if
any, shall become due and payable on such prepayment date; provided, that if no
later than 5 days prior to the required prepayment date any Noteholder who shall
have received such notice notifies the Company that such Noteholder waives any
right it has to receive Additional Payments arising out of the circumstances
described in the notice from the Company, then the Notes held by such Noteholder
shall not be

                                        3

<PAGE>



prepaid pursuant to this paragraph 4E(b) but shall remain outstanding. Any such
waiver from a Noteholder shall apply only to Additional Payments arising out of
the circumstances described in the notice from the Company and shall not be
treated as a waiver by such Noteholder of its right to receive Additional
Payments which arise under any other circumstances or are in any other amount,
it being understood that the Company is entitled to deliver to all applicable
Noteholders a new notice under this paragraph 4E(b) with respect to any such
other Additional Payments. Any waiver made by a Noteholder hereunder is
revocable upon at least 60 days notice; provided that prior to the expiration of
such period such Noteholder shall not be entitled to such Additional Payment
which was the subject of such waiver.

      (c) For purposes of this paragraph 4E "Special Tax Event" shall mean a
Change in Tax Law which in the opinion of the Company shall require Additional
Payments. Such opinion shall be evidenced by an Officer's Certificate of the
Company and supported by a written opinion of independent tax counsel of
recognized standing in the relevant taxing jurisdiction (which counsel shall be
reasonably satisfactory to the Required Holders), each of which shall be
delivered to the relevant holders of Notes not later than 10 Business Days prior
to the date fixed for prepayment.

      4F. Prepayment upon a Change of Control. (a) Within 5 Business Days
following the date a Responsible Officer obtains knowledge of any Change of
Control, the Company shall give written notice of such Change of Control (a
"Change of Control Notice") to each Noteholder, which shall (i) describe the
facts and circumstances of such Change of Control in reasonable detail, (ii)
refer to this paragraph 4F(a) and the rights of the Noteholders hereunder, (iii)
inform each Noteholder that unless they instruct the Company otherwise, the
Company shall prepay the entire unpaid principal amount of Notes held by each
Noteholder, together with any accrued and unpaid interest thereon from and
including the immediately preceding interest payment date, to but excluding the
prepayment date selected by the Company, together with Yield-Maintenance Amount,
if any, with respect to each Note (showing in such offer the amount of interest
which would be paid on such prepayment date and an estimate of the
Yield-Maintenance Amount together with the calculation of such estimated
amount), which prepayment shall be on a date specified in the Change of Control
Notice, which date shall be a Business Day not more than 20 days after the date
of such Change of Control Notice (the "Change of Control Prepayment Date") and
(iv) request each Noteholder to notify the Company in writing by a stated date,
which date is not less than 10 days after such Noteholder's receipt of the
Change of Control Notice, if such Noteholder does not wish its Notes to be so
prepaid. Promptly after the date on which the Yield-Maintenance Amount can be
calculated, the Company shall notify each Noteholder in writing which has not
rejected such prepayment of the precise amount of the Yield-Maintenance Amount,
showing the Company's computation thereof in reasonable detail.

      (b) On the Change of Control Prepayment Date the entire unpaid principal
amount of the Notes held by each holder of Notes who has not notified the
Company that such Noteholder does not wish its Notes to be prepaid (in

                                        4

<PAGE>

accordance with paragraph 4F(a)(iv) above, together with any accrued and unpaid
interest thereon from and including the immediately preceding interest payment
date or the Date of Closing, as the case may be, to but excluding the Change of
Control Prepayment Date and together with the Yield-Maintenance Amount, if any,
with respect to each such Note, shall become due and payable.

      (c) The Company will promptly provide any holder of a Note with all
information which it may reasonably request in order to enable such holder to
evaluate the effect of a Change of Control on such Noteholder's investment in
the Notes, including without limitation copies of all such documents as may have
been sent to the shareholders of the Company by or on behalf of the Company or
any Person which has made an offer which, if accepted, would give rise to a
Change of Control.

      5. AFFIRMATIVE COVENANTS OF THE COMPANY. The Company covenants and agrees
that unless Majority Creditors shall otherwise agree and so long as any Note is
outstanding:

      5A. Financial Statements. The Company covenants that it will deliver to
each Noteholder in duplicate (or such less number as any Noteholder shall
request):

      150 days (in the case of the Accounts of the Company) or 210 days (in the

      of its Financial Years, as the case may be, the Accounts of itself and
      each Significant Subsidiary for the relevant Financial Year together with
      a copy of the management letter (if any) addressed by the Auditors to the
      directors of the Company;

      Company, 90 days), after the end of each period of 3 months ending on a
      Quarter Day, quarterly management accounts of the Group in a format
      satisfactory to the Required Holder(s) (including a profit and loss
      account and cashflow forecast) and attaching an information schedule (in
      the agreed form) setting out EBITDA, Total Debt Costs and Recurring UK
      Rental Income for such three-month period together with details of
      progress on any proposed asset disposals and contracts taken on or

      month including a statement of profit and loss, a cashflow statement, a
      cashflow forecast for the balance of the then current Financial Year of
      the Company and an update on matters referred to in the Side Letter;

            (v) within a reasonable time following transmission thereof, (a) all
      such financial statements, proxy material, notices and reports as it shall
      send to its public shareholders or its creditors generally (or any class
      thereof) and (b) all registration statements (without exhibits),
      prospectuses and all reports which it files with the Securities and
      Exchange Commission (or any governmental body or agency succeeding to the
      functions of the Securities and Exchange Commission), The International
      Stock Exchange of the United Kingdom and the Republic of Ireland Limited
      or any stock exchange except where the Company shall, at the expense of
      the Company, provide the Noteholders with an opinion of counsel that doing
      so would cause the Company to subject itself to requirements of US Federal
      or state securities laws or UK securities laws to which it would not
      otherwise be subject; and

            (vi) prompt notice of any litigation, arbitration or administrative
      proceeding commenced against any member of the Group involving a potential
      claim of (pound)100,000 or greater.

Together with each delivery of financial statements required by clause (iii)
above, the Company will deliver to each Noteholder an Officer's Certificate
demonstrating (with computations in reasonable detail) compliance by the Company
and its Subsidiaries with the provisions of paragraph 6 and stating that there
exists no Event of Default or Default, or, if any Event of Default or Default
exists, specifying the nature and period of existence thereof and what action
the Company proposes to take with respect thereto. Together with each delivery
of financial statements required by clauses (i) and (ii) above, the Company will
deliver to each Noteholder an Officer's Certificate demonstrating, with
computations in reasonable detail, compliance by the Group with the provisions
of paragraphs 6A, 6B, 6C, 6D, 6F, 6G, 6H and 6I and stating that there exists no
Event of Default or Default, or, if any Event of Default or Default exists,
specifying the nature and period of existence thereof and what action the
Company proposes to take with respect thereto. Together with each delivery of
financial statements required by clause (i) above, the Company will also deliver
to each Noteholder a certificate of the accountants referred to in that clause
stating that, in making the audit necessary to the certification of such
financial statements, they have obtained no knowledge of any Event of Default or
Default, or, if they have obtained knowledge of any Event of Default or Default,
specifying the nature and period of existence thereof. Such accountants,
however, shall not be liable to anyone by reason of their failure to obtain
knowledge of any Event of Default or Default which would not be disclosed in the
course of an audit conducted in accordance with generally accepted auditing
standards. The Company also covenants that forthwith upon a Responsible Officer
of the Company obtaining actual knowledge of an Event of Default or Default, it
will deliver to each Noteholder an Officer's Certificate specifying the

                                        6

<PAGE>

nature and period of existence thereof and what action the Company proposes to
take with respect thereto.

     If and to the extent required by Rule 144A(d)(4)(i) under the Securities
Act in connection with a resale of the Notes exempt from the registration
requirements of the Securities Act pursuant to Rule 144A, the Company shall
provide (x) to any Noteholder, promptly, at the request of such Noteholder, such
additional information regarding the Company as is specified in Rule
144A(d)(4)(i) and (y) to a prospective transferee of any Note designated by a
Noteholder, which transferee is qualified to purchase the Note under Rule
144A(d)(l), the information described in the foregoing sub-paragraph (x).

     5B. Inspection of Property. The Company covenants that it will comply with
any reasonable written request of any Noteholder to visit and inspect, at such
Noteholder's expense (except upon the occurrence of a Default or an Event of
Default), any of the properties of the Company and its Subsidiaries and to
discuss the affairs, finances and accounts of any of such corporations with the
principal officers of the Company and its independent public accountants, all at
such reasonable times and as often as such Noteholder may reasonably request. At
the request of any Noteholder wishing to have discussions with the independent
accountants of the Company in accordance with this paragraph 5B, the Company in
good faith shall instruct such accountants to hold such discussions; provided
that the Company shall not be held responsible for the failure of its
accountants to hold such discussions in accordance with such instructions. Each
Noteholder agrees that any non-public materials and information obtained by such
Noteholders as a result of any such visit, inspection or discussion shall be
treated in a confidential manner consistent with the provisions of paragraph
llI.

     5C. Consents. The Company shall obtain, comply with the terms of and do all
that is necessary to maintain in full force and effect (and promptly supply to
any Noteholder at such Noteholder's request certified copies of) all
authorizations, approvals, licenses and consents required to enable it lawfully
to enter into and perform its obligations under this Agreement, the Notes, the
Security Documents or to ensure the legality, validity, binding effect or
admissability in evidence in New York of this Agreement, the Notes and the
Security Documents.

     5D. Insurance. The Company shall, and shall cause each of its Subsidiaries
to, effect and maintain with financially sound and reputable insurers (including
self-insurance) such insurance over and in respect of its respective assets and
business and in such manner and to such extent as is reasonable and customary
for a business enterprise engaged in the same or a similar business and in the
same or similar location.

     5E. Maintenance or Status and Business. The Company shall:

          (i) do all such things as are necessary to maintain its corporate
     existence, and cause each of its Subsidiaries to maintain their


                                       7
<PAGE>

     corporate existence, except, in the case of its Subsidiaries, where the
     failure to do so would not have, individually or in the aggregate, a
     Material Adverse Effect and except as otherwise permitted by paragraph 6G
     hereof;

          (ii) ensure that it, and each of its Subsidiaries, has the right and
     is duly qualified to conduct its business as it is conducted in all
     applicable jurisdictions and will obtain and maintain all rights necessary
     for the conduct of its business, except where the failure to do so would
     not result in a Material Adverse Effect; and

          (iii) at all times comply and cause each of its Subsidiaries to comply
     with all laws and with all rules, regulations and orders made by any
     governmental authority applicable to it or to any of its Subsidiaries or to
     its Property or Property of any of its Subsidiaries, except where the
     failure to do so would not result in a Material Adverse Effect.

     5F. Prompt Payment of Taxes. The Company covenants that it will promptly
pay and discharge, and that it will cause each of its Subsidiaries promptly to
pay and discharge, or cause to be paid and discharged, prior to the earliest
date on which any penalty or interest is incurred or begins to accrue, all
lawful taxes, assessments and governmental charges or levies imposed upon any of
its income, profits, Property or business unless, and only to the extent that,
(x) (i) such taxes, assessments and governmental charges or levies are being
contested in good faith by appropriate proceedings, (ii) adequate reserves have
been established in accordance with U.K. GAAP, and (iii) title to or the right
to use Property of the Company is not materially adversely affected thereby or
(y) nonpayment of such taxes, assessments and governmental charges or levies
would not be expected to result in a Material Adverse Effect.

     5G. Maintenance of Property and Leases. The Company will maintain, and will
cause each of its Subsidiaries to maintain, all the Property used in its or any
Subsidiary's business in good operating condition, reasonable wear and tear
excepted, except for Property the uninsured loss of which would not have a
Material Adverse Effect. The Company will comply at all times, and will cause
each of its Subsidiaries to comply at all times, with the provisions of all
material leases to which it or any Subsidiary is a party or under which it
occupies Property except where the failure so to comply would not result in a
Material Adverse Effect.

     5H. Use of Proceeds. The Company does not own or have any present intention
of acquiring any "margin stock" as defined in Regulation G (12 CFR Part 207) of
the Board of Governors of the Federal Reserve System the (herein called "margin
stock"). Neither the Company nor any agent acting on its behalf will take any
action which might cause this Agreement or the Notes to violate Regulation G,
Regulation T or any other Regulation of the Board of Governors of the Federal
Reserve System or to violate the Exchange Act, in each case as the same may now
or hereafter be in effect.


                                       8
<PAGE>

     5I. Environmental Matters. The Company: (i) shall conduct, and shall cause
each of its Subsidiaries to conduct, its business in compliance with all
Environmental Laws applicable to it, including without limitation, those
relating to the generation, handling, use, treatment, storage and disposal of
Hazardous Materials by the Company and its Subsidiaries, except where the
failure so to conduct would not individually or in the aggregate, have a
Material Adverse Effect and (ii) shall take, and shall cause each of its
Subsidiaries to take, appropriate action to respond to any non-compliance with
Environmental Laws or any environmental claim, except where the failure so to
take would not individually or in the aggregate, have a Material Adverse Effect.

     5J. Financial Records. The Company will, and will cause each of its
Subsidiaries to, keep proper books of account in accordance with generally
accepted accounting principles of the applicable jurisdiction, except in respect
of any of its Subsidiaries where the failure to do so, individually or in the
aggregate, would not have a Material Adverse Effect.

     5K. Share Pledge. The Company shall procure that, upon the discharge of the
Sanwa Facility, ASC shall forthwith execute a Share Pledge pledging to the
Security Trustee the remaining 90% of the shares of API which are not subject to
a Share Pledge and provide to the Security Trustee, in form and substance
satisfactory to the Required Holder(s), a legal opinion in respect thereof

which would require the registration of the Notes under the provisions of

case as in effect now or as the same may hereafter be in effect.

     8N. Pension Plans. Each Plan is in substantial compliance with ERISA and
the Code except to the extent that any failure to substantially comply does not

defined by ERISA Section 4001, which is subject to Title IV of ERISA; no Plan is
insolvent or in reorganization; all contributions required to be made with
respect to all Plans and Foreign Pension Plans have been timely made; neither
the Company nor its Subsidiaries nor any ERISA Affiliate has incurred any
material liability to or on account of a Plan, including a plan maintained or

4062, 4063, 4064, 4069, 4201, 4204 or 4212 of ERISA or Section 401(a) (29) of
the Code: neither the Company nor its Subsidiaries has incurred any material
liability to or on account of a Plan pursuant to Section 4971, 4975 or 4980 of
the Code and neither the Company nor its Subsidiaries, nor any ERISA Affiliate,
where applicable, expects to incur any liability (including any indirect,
contingent, or secondary liability) under any of the foregoing Sections with
respect to any Plan, including a plan maintained by an ERISA Affiliate except
with respect to Code Sections 4971, 4975 or 4980; no proceedings have been
instituted to terminate or appoint a trustee to administer any Plan; no
condition exists which presents a material risk to the Company or any of its
Subsidiaries or any ERISA Affiliate, where applicable, of incurring a liability
to or on account of a Plan pursuant to the foregoing provisions of ERISA and the
Code; no Lien imposed under the Code or ERISA on the assets of the Company or

account of any Plan, including a plan maintained or contributed to by an ERISA
Affiliate; and the Company and its Subsidiaries may cease contributions to or
terminate any employee benefit plan maintained by any of them without incurring
any material liability in an amount that would affect the ability of the Company
or its Subsidiaries to meet it obligations under this Agreement. Each Foreign
Pension Plan has been maintained in substantial compliance with its terms and
with the requirements of any and all applicable laws, statutes, rules,
regulations and orders, except to the extent that any failure to substantially
comply does not cause the Company or its Subsidiaries to incur a material
liability. Neither the Company nor any of its Subsidiaries has incurred any
obligation in connection with the termination of or withdrawal from any Foreign
Pension Plan. The present value of the accrued benefit liabilities (whether or
not vested) under each Foreign Pension Plan, determined as of the end of the

assumptions, each of which is reasonable, did not exceed the current value of
the assets

Subsidiaries, taken as a whole, or the Company's ability to perform its
obligations under this Agreement.

respective properties and facilities have complied with all laws, including
Environmental Laws, regulations and orders relating to the protection of the
environment except where failure so to comply would not have a Material Adverse
Effect.

     8P. Legal Validity. This Agreement, each Note and the First Amendment
constitutes, and each of the Security Documents will (when executed by the other
parties thereto) constitute, the legal, valid and binding obligation of the
Company or the Subsidiary party thereto, as the case may be, enforceable in
accordance with its respective terms, except as such enforceability may be
limited by (a) bankruptcy, insolvency, reorganization or other similar laws
affecting the enforcement of creditors' rights generally and (b) general
principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law).

directly or indirectly controlled by any person which is, required to register
as an "investment company" within the meaning of the Investment Company Act of

Chartered Accountants in England and Wales to nominate a firm of chartered
accountants. Such accountants shall act as experts and not arbitrators and their
decision shall be final and binding on the Company and the Noteholders. The
costs of such experts shall be paid by the Company.

Company and the Noteholders and be reset to reflect the change in the Company's
financial position as a result thereof but on the basis that while reflecting
such change, the reset financial covenants will provide the Noteholders with
substantially the same protection as the financial covenants set out in
paragraph 6.

such Note to any Person on such terms and conditions as may be determined by

                                       41

<PAGE>

may be brought by such holder of a Note in the United States District Court for
the Southern District of New York or any New York State Court siting in New York
City as such holder of a Note may in its sole discretion elect, and, by the
execution and delivery of this Agreement, irrevocably submits to the
jurisdiction of each such court; and agrees that process served either
personally or by registered mail shall, to the extent permitted by law,
constitute adequate service of process in any such suit. Without limiting the

proceeding brought in the courts of or in the State of New York, CT Corporation
System, with offices on the Effective Date at 1633 Broadway, New York, New York
10019, to receive, for it and on its behalf, service of process in the State of

waives any claim that any such suit, action or proceeding brought in any such
court has been brought in an inconvenient forum. Nothing herein shall in any way
be deemed to limit the ability of any holder of a Note to serve any such writs,
process or summonses, in any manner permitted by applicable law or to obtain
jurisdiction over the Company, in such other jurisdiction, and in such manner,
as may be permitted by applicable law.

      11O. Gross-up. All payments whatsoever by the Company under this Agreement
or the Notes shall be made by the Company from either the United Kingdom, the
United States or the jurisdiction in which the Company is organized in the
lawful currency of the United States of America free and clear of, and without
reduction or liability for or on account of, tax unless any withholding or
deduction for or on account of tax is required by law.

      If the Company shall be obligated by law to make any such withholding or
deduction for any tax (excluding any taxes imposed by the United States of
America or a political subdivision or taxing authority thereof or therein)
imposed by the United Kingdom or the jurisdiction in which the Company is
organized, then the Company will promptly (i) notify the affected holder of a
Note of such requirement, (ii) pay over to the government or taxing authority
imposing such tax the full amount required to be deducted, withheld or otherwise
paid by the Company (including the full amount required to be deducted or
withheld from or otherwise paid by the Company in respect of any Additional
payment (as defined below) required to be made pursuant to clause (iv) hereof),
(iii) furnish such holder with the original receipt of such payment from such
government or taxing authority (or such other evidence sufficient under Treasury
Regulations 1.904-2(a)(2) under the Internal Revenue Code of 1986, as amended
(or any successor or subsequent provisions)), and (iv) save as provided below,
pay to each Person entitled under this Agreement or the Notes to receive the
payment from which the amount referred to in clause (ii) has been so deducted,
withheld

                                       42

<PAGE>

or otherwise paid such additional amount as is necessary in order that the
amount received by such Person after such required deduction or withholding
(including any required deduction or withholding on or with respect to such
additional amount), shall equal the amount such Person would have received had
no such deduction or withholding been made (the "Additional Payment"), provided
that no Additional Payment shall be payable with respect to any amount payable
under this Agreement or the Notes to any Person if:

      (1) so long as no Change in Tax Law has occurred which changes the ability
      or right of such holder to file such form or changes the substance of such
      form, such holder fails to file a validly completed and executed Form FD13
      with the United States Internal Revenue Service prior to the relevant
      interest payment date in sufficient time such that the company shall
      actually have received a direction to pay gross from the United Kingdom
      Inspector of Foreign Dividends,

      (2) such holder fails to be a resident of the United States of America
      within the meaning of the income tax treaty between the United States of
      America and the United Kingdom (but only to the extent the amount of such
      deduction or withholding exceeds that which would have been required had
      such Person been resident in the United States of America), or

      (3) such tax would not have been imposed but for the existence of any
      present or former connection between such holder and the United Kingdom,
      other than the mere ownership of, or receipt of payments under the Notes.

The provisions of clause (1) above shall not be applicable to a holder of a Note
which is a Purchaser so long as such holder files within 30 days after the
Closing Date a validly completed and duly executed Inland Revenue Form FD13 with
the Internal Revenue Service as required to establish their entitlement to an
exemption from U.K. withholding tax under the income tax treaty currently in
force between the United States and the United Kingdom. If the Company fails to
pay any withheld or deducted taxes imposed by the United Kingdom or the
jurisdiction in which the Company is organized in accordance with clause (ii) of
this paragraph 11O in accordance with applicable law, then the Company will
indemnify and hold harmless the affected Person and reimburse such Person on an
after-tax-basis for the amount of such taxes, penalties, interest and additions
to tax imposed on and paid by such Person.

      Each holder of a Note agrees that, upon the written request of the Company
and to the extent it is legally entitled to do so, it will file any forms,
certificates, documents, applications or returns, or other reasonably required
evidence as specified in such request (collectively, "Forms"), which are
required to be filed by such holder to avoid or to reduce any taxes
indemnifiable by the Company under this paragraph 11O, provided that the filing
of any such Form does not require the holder to reveal any confidential or
proprietary tax return

                                       43

<PAGE>

or other information and does not require the holder to incur any unreasonable
expense.

      If the Company is required to pay an Additional Payment with respect to
any taxes pursuant to this paragraph 11O to or on behalf of a holder of a Note
and such holder subsequently receives a refund of such taxes, then such holder
shall reimburse the Company the amount of such refund net of any taxes payable
by the holder in respect of the receipt thereof; provided, however, that no such
amount shall be payable (x) while a Default or Event of Default shall have
occurred and be continuing and (y) to the extent such amount exceeds the amount
of the taxes to which such refund relates.

      The obligations of the Company and the Noteholders under this paragraph
11O shall survive the payment of the Notes.

      11P. Judgment Currency Indemnity. Any payment on account of any amount
that is payable hereunder in Dollars which is made to or of the account of any
Noteholder in the lawful currency of any other jurisdiction ("currency"),
whether as a result of any judgment or order or the enforcement thereof or the
realization of any security or the liquidation of the Person obligated to make
such payment shall constitute a discharge of the such Person's obligation under
this Agreement or the Notes only to the extent of the amount of dollars which
such Noteholder could purchase in the London foreign exchange markets with the
amount of other Currency in accordance with normal banking procedures at the
rate of exchange prevailing on the first day (other than a Saturday) on which
banks in London are generally open for business following receipt of the payment
first referred to above. If the amount of Dollars that could be so purchased is
less than the amount of Dollars originally due to such Noteholder, the Person
obligated hereunder to make such payment shall indemnify and save harmless such
Noteholder from and against all loss or damage arising out of or as a result of
such deficiency. This indemnity shall constitute an obligation separate and
independent from the other obligations contained in this Agreement or the Notes,
shall give rise to a separate and independent cause of action, shall apply
irrespective of any indulgence granted by such Noteholder from time to time and
shall continue in full force and effect notwithstanding any judgment or order
for a liquidated sum in respect of an amount due hereunder or under any judgment
or order.

      11Q. Severability. Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

      11R. Counterparts. This Agreement may be executed simultaneously in two or
more counterparts, each of which shall be deemed an original, and it shall not
be necessary in making proof of this Agreement to produce or account for more
than one such counterpart.

<PAGE>

3.   SECURITY TRUSTEE

3.1  Each Creditor hereby irrevocably appoints the Security Trustee to act as
     its agent and trustee in connection with the Security Documents and this
     Agreement and, subject to the other terms hereof, for such purposes
     irrevocably authorises the Security Trustee to take such action and to
     exercise and carry out all the discretions, authorities, rights, powers and
     duties as are specifically delegated to the Security Trustee in each of
     this Agreement and the Security Documents together with such powers and
     discretions as are incidental thereto. The Security Trustee shall have no
     duties or responsibilities except those expressly set out in this Agreement
     and the Security Documents.

3.2  The Security Trustee shall, subject to the other terms hereof, act
     hereunder and under the Security Documents in accordance with the
     instructions of the Majority Creditors and any such instructions given
     pursuant to this sub-Clause 3.2 and any action taken by the Security
     Trustee in connection therewith shall be binding upon all the Creditors.

3.3  The Security Trustee shall not be obliged to take any steps to ascertain
     whether any Default (as defined in the Credit Agreement or the US Loan
     Notes Instrument) has happened or exists and, until the Security Trustee
     shall have received express notice to the contrary from a Creditor, the
     Security Trustee shall be entitled to assume that no Default (as so
     defined) has happened or exists.

3.4  The Security Trustee will be entitled to rely on any communication or
     document believe by it to be genuine and correct and to have been
     communicated or signed by the person by whom it purports to be communicated
     or signed and shall not be liable to any of the parties to this Agreement
     for any of the consequences of such reliance.

3.5  The Security Trustee shall not be obliged to take or commence any legal
     action or proceeding against any person, body or corporation arising out of
     or in connection with this Agreement or the Security Documents until it
     shall have been indemnified or secured to its satisfaction against any and
     all costs, claims and expenses (including, but not limited to, legal fees
     and expenses which it may expend or incur in such legal action or
     proceeding).

3.6  Neither the Security Trustee nor any of its directors, employees or agents
     shall be liable for any action taken or omitted to be taken by it or any of
     them under or in connection with this Agreement or the Security Documents
     unless caused by its or their negligence or wilful misconduct. The Security
     Trustee shall not be responsible for any statements, representations or
     warranties in this Agreement or the Security Documents or for any
     information supplied or provided or hereafter to be supplied or provided to
     the Creditors, in respect of any matter relating to this Agreement, the
     Security Documents or for the execution, effectiveness, genuineness,
     validity, enforceability or sufficiency of such documents or any of the
     other documents referred to herein or therein or for the recoverability of
     any of the Bank Liabilities or the Note Holder Liabilities or any of the
     other sums to become due and payable pursuant hereto.
<PAGE>

3.7  Each Creditor acknowledges that it has, independently and without reliance
     on the security Trustee and based on such documents and information as is
     deemed appropriate, made its own analysis of the transactions contemplated
     by the Financing Agreements, reached its own decision to enter into the
     relevant Financing Agreements and made its own investigation of the
     financial condition and affairs of each member of the Group and its own
     appraisal of the credit worthiness of each member of the Group. Save as
     specifically provided herein the Security Trustee shall not be under any
     duty or obligation, either initially or on a continuing basis, to provide
     any Creditor with any credit information or other information with respect
     to the financial condition of any member of the Group. Each Creditor
     further acknowledges that it will, independently and without reliance on
     the Security Trustee and based on such documents and information as it
     shall deem appropriate at the time, make its own decisions in taking or not
     taking action under this Agreement and the Security Documents.

3.8  The Security Trustee shall be entitled to obtain and rely on the advice of
     any professional advisers selected by it given in connection with this
     Agreement and the Security Documents or any of the matters contemplated
     hereby or thereby, and shall not be liable to the Creditors or any of them
     for any of the consequences of such reliance.

3.9  With respect to its own participations in any of the Bank Liabilities or
     the Note Holder Liabilities, the Security Trustee shall have the same
     rights and powers under and in respect of this Agreement and the Security
     Documents as though it was not also acting as agent and trustee for the
     Creditors. The Security Trustee may, without liability to account, accept
     deposits from, lend money to and generally engage in any kind of banking or
     trust business with or for the Company as if it was not the agent and
     trustee for the Creditors.

3.10 The Creditors agree to indemnify the Security Trustee (to the extent not
     reimbursed by members of the Group) rateably according to that part of the
     aggregate of the Bank Liabilities and the Note Holder Liabilities owed to
     each Creditor from and against any and all liabilities, obligations,
     losses, damages, penalties, actions, judgments, suits, costs, expenses and
     disbursements of any kind or nature whatsoever which may be imposed on,
     incurred by or asserted against the Security Trustee in its capacity as
     agent and trustee for the Creditors or in any way relating to or arising
     out of this Agreement and the Security Documents or any action taken or
     omitted by the Security Trustee in enforcing or preserving the rights of
     the Creditors under this Agreement and the Security Documents provided that
     no damages, penalties, actions, judgments, suits, costs, expenses or
     disbursements resulting from the Security Trustee's negligence or wilful
     misconduct PROVIDED THAT no Creditor shall be liable in the aggregate to
     the Security Trustee for an amount in excess of the Principal Bank
     Liabilities or the Principal Note Holder Liabilities owed to such Creditor.

3.11 Subject to the appointment and acceptance of a successor Security Trustee
     as provided below, the Security Trustee may resign at any time by giving to
     the Agent 
<PAGE>

     and the US Loan Note Holder not less than thirty (30) days' notice of its
     intention to do so. Upon receipt of such notice or resignation the
     Creditors shall appoint as successor Security Trustee any bank or financial
     institution selected by the Majority Creditors which is willing and able to
     act as such agent for the Creditors. If no such successor Security Trustee
     is selected within thirty (30) days after such Security Trustee's giving of
     notice of resignation then the Security Trustee shall have the right to
     appoint such a successor Security Trustee. Any such appointment shall take
     effect upon notice thereof being given to the Agent and the US Loan Note
     Holder. Thereafter, the resigning Security Trustee shall be discharged from
     any further obligation under this Agreement and the Security Documents and
     its successor and each of the other parties hereto and thereto shall have
     the same rights and obligations inter se as they would have had if such
     successor had been a party to this Agreement and the Security Documents in
     place of the resigning Security Trustee. The resigning Security Trustee
     shall make over to its successor all such records as its successor requires
     to carry out its duties.

3.12 The Security Trustee may from time to time in its sole discretion by
     written notice to the Agent and the US Loan Note Holder designate a
     different office in the United Kingdom from which its duties as the
     Security Trustee will thereafter be performed.

3.13 The Security Trustee shall accept without investigation, requisition or
     objection such title as any person may have to the undertaking, property
     and assets the subject of the Security Documents and shall not be bound or
     concerned to examine or enquire into nor be liable for any defect or
     failure in the title of any person whether such effect or failure was known
     to the Security Trustee or might have been discovered upon examination or
     enquiry and whether capable of remedy or not nor for any failure on the
     part of the Security Trustee to give notice to any third party of the
     Security Documents or otherwise perfect or register the security thereby
     created.

3.14 Each of the Creditors hereby confirms and agrees that it does not wish to
     be registered in accordance with Rule 146 of the Land Registration Rules
     1925 as the joint proprietor of any mortgage or charge created pursuant to
     any Security Documents and accordingly authorises the Security Trustee to
     hold such mortgage or charge in its sole name as Trustee for the Creditors
     and hereby requests HM Land Registry to register the Security Trustee as
     the sole proprietor of any such mortgage or charge.

3.15 The Security Trustee may:

     (a)  act as agent or trustee or in a fiduciary or other capacity on behalf
          of any other group of banks or financial institutions providing
          facilities to any member of the Group or any associated company of a
          member of the Group or any associated company of a member of the Group
          without regard to the effect of exercising or omitting to exercise its
          discretions, authorities, rights, powers and duties in such capacity
          in the interests of the Creditors and may act or omit to act in such
          capacity as freely in all 
<PAGE>

          respects as if the Security Trustee had not been appointed to act as
          agent for the creditors; and

     (b)  subscribe for, hold or be or become beneficially entitled to, or
          dispose of, shares or securities, or options or other rights to and
          interests in shares or securities in any member of the group or any
          associated company of a member of the Group (and, in each case, may do
          so without liability to account).

3.16 For so long as Lloyds Bank Plc is the Security Trustee, the Capital Markets
     Group of Lloyds Bank Plc shall be treated as a separate entity from any
     other of the divisions of the Security Trustee or its Subsidiaries and,
     notwithstanding the generality of the foregoing, in the event that any of
     the Security Trustee's divisions (including its Capital Markets Group) or
     similar units or Subsidiaries should act of any member of the Group in any
     capacity (whether as bankers or otherwise) in relation to any other matter,
     any information given by any member of the Group to such divisions, similar
     units or Subsidiaries shall be treated as confidential and the Security
     Trustee shall, as between itself and the Creditors, not be obliged to
     disclose the same to any Creditor or any other person.

3.17 For the purposes of this Agreement, the Security Trustee shall be deemed
     not to have any actual knowledge or actual notice of the contents of any
     information obtained by it or supplied to it by or on behalf of any member
     of the Group other than the contents of information obtained by or supplied
     to it as Security Trustee for the Creditors pursuant to or in connection
     with this Agreement.

4.   ENFORCEMENT

     At any time after the Liabilities have become immediately due and payable
     pursuant to Clause 15.2 of the Credit Agreement and paragraph 7A of the US
     Loan Notes Instrument, the Security Trustee shall enforce the Security
     Documents as directed by the Majority Creditors.

5.   DISTRIBUTION OF ENFORCEMENT PROCEEDS

5.1  On the enforcement (whether successful or not) of any or all of the
     Security Documents, the Security Trustee shall be entitled to deduct from
     the proceeds of each enforcement (which expression shall include all
     amounts realized or recovered by the Security Trustee on or after such
     enforcement) its costs, charges and expenses incurred in connection with
     such enforcement.

5.2  Each Creditor and the Security Trustee hereby agrees that any credit
     balance held with a Bank which is taken into account by such Bank when
     providing an overdraft under the terms of the Credit Agreement up to a net
     limit may be set-off and applied against any debit balance on the relevant
     overdraft at any time after such debit balance becomes immediately due and
     payable and the Creditors (other than 
<PAGE>

     such Bank) and the Security Trustee shall have no claim to, or interest in,
     any credit balance so applied.

5.3  After making any deductions allowed by Clause 5.1, all proceeds of
     enforcement of the Security Documents shall be applied:

     (i)  first, by distributing such proceeds to the Agent for the account of
          itself and the Banks up to an aggregate amount not exceeding the
          amount in Sterling by which the aggregate principal amount outstanding
          under the Credit Agreement (as at the date the Agent serves notice
          under Clause 15.2.1 of the Credit Agreement) exceeds (pound)81,641,000
          (and for these purposes amounts denominated in currencies other than
          Sterling will be taken into account on the basis of the Sterling
          Equivalent thereof as at such date) PROVIDED THAT the proceeds
          distributed under this sub-Clause (i) shall not exceed
          (pound)5,000,000 and FURTHER PROVIDED THAT this Clause (i) shall be of
          no further force or effect following the reduction of the Facilities
          contemplated by sub-Clauses (a) and (b) of Clause 10.2.1 of the Credit
          Agreement;

     (ii) secondly, after the application referred to in (i) above, by
          distributing such proceeds to the Agent for the account of the Banks
          for application against the Bank Liabilities and to the US Loan Note
          Holders for application against the Note Holder Liabilities pro rata
          to the Adjusted Bank Principal Liabilities and the Adjusted Note
          Principal Liabilities (calculated in Sterling using the relevant spot
          rate of exchange at the time of distribution) PROVIDED THAT after the
          first of either the Bank Liabilities or the Note Holder Liabilities
          having been discharged in full then all proceeds shall go solely to
          the payment of whichever of the Bank Liabilities or the Note Holder
          Liabilities which remains undischarged; and

     (iii)thirdly, after the discharge in full of the Liabilities, by
          distributing the remaining proceeds of enforcement to the person or
          persons next entitled to them.

5.4  The Security Trustee shall notify the Creditors of any proposed
     distribution and the proposed date of distribution.

5.5  If any future and/or contingent liability included in any calculation of
     the Liabilities finally matures or is settled for less than the future
     and/or contingent amount provided for in the relevant calculation, the
     relevant Creditor shall notify the Security Trustee of that fact and such
     adjustment shall be made by payment by such Creditor to the Security
     Trustee for distribution amongst the other Creditors as may be necessary to
     put the Creditors into the position they would have been in (but taking no
     account of the time cost of money) had the original distribution been made
     on the basis of the actual as opposed to the future and/or contingent
     liability.

5.6  The Security Trustee may, at its discretion, accumulate proceeds of
     enforcement and/or disposals on an interest bearing account in its own name
     until there is a minimum of (pound)1,000,000 to distribute under Clause
     5.3.

6.    SHARING PROPORTIONS ADJUSTMENTS

6.1   At the time of any relevant distribution, the Sharing Proportions shall be
      determined as follows:

      (i)  the Sharing Proportion of the Banks (rounded to four decimal places)
           shall be calculated as follows:

                       Maximum principal available amount
                   of the Facilities immediately prior to the
                                  distribution
                  --------------------------------------------- x100
                    The principal amount of the US Loan Notes
                   and the maximum principal available amount
                   of the Facilities immediately prior to the
                                  distribution

      (ii) The Sharing Proportion of the US Loan Note Holders (rounded to four

                        Principal amount of US Loan Notes
                      immediately prior to the distribution
                  --------------------------------------------- x100

      used.

      or any other type of decision (the "Consent") of the Majority Creditors,
      the Company shall inform the Banks (through the Agent) and the US Loan
      Note Holders of the Consent that is required. Once they have considered
      the relevant matter, each Bank (through the Agent) and each US Loan Note
      Holder will inform the Security Trustee whether or not they are prepared
      to give the relevant Consent. As soon as practicable, the
<PAGE>

      Security Trustee will inform the Company, the Agent and the US Loan Note
      Holders whether or not the Majority Creditors have given the relevant
      Consent.

7.1.2 If the Creditors are requested to amend the financial covenants in the
      Credit Agreement and the US Loan Notes Instrument the Security Trustee
      will convene such meetings as are necessary for the purpose of considering
      the proposed amendments and will inform the Company of the decision of the
      Majority Creditors as and when such decision is made. In the event that
      amended financial covenants are agreed by the Majority Creditors each of
      the parties hereto agrees to amend the Credit Agreement and the US Loan
      Notes Instrument accordingly.

7.1.3 Notwithstanding any other provision of this Agreement, without the consent
      of the Required Holder(s), the Majority Creditors shall not consent to the
      securing by any member of the Group of any part of the Liabilities unless
      the Note Holder Liabilities are secured on a pro rata basis.

8.    AMENDMENTS TO THE FINANCING AGREEMENTS

8.1   The US Loan Note Holders hereby undertake with the Banks that, while the
      Bank Liabilities are outstanding, they shall not consent to any amendment
      or variation of the maturity or interest rate of the US Loan Notes or
      paragraphs 4A, 4B, 4F, 5, 6, 7, 8, 11C and 11E and so far as it relates to

      prior consent of the Majority Banks.

      Note Holder Liabilities are outstanding, they shall not consent to any
      amendment or variation of Clauses 8, 9, 13, 14 and 15 and, in so far as it
      relates to any of the same, Clause 1 of the Credit Agreement without the
      prior consent of the Required Holders.

9.    REPAYMENT AND PREPAYMENTS

      For the avoidance of doubt, it is hereby agreed that all repayment and
      prepayment provisions contained in the Financing Documents may not be
      waived by the Majority Creditors.

10.   RELEASES

      The Security Trustee is hereby authorized to release assets from the
      Security Documents which are or are to be the subject of a Disposal in
      circumstances where such Disposal is permitted pursuant to the terms of
      the Credit Agreement and the US Loan Notes Instrument.

      facsimile number as may be notified by the relevant party to the other
      parties for the purpose of this Clause 16.4 and in the case of notices to
      and from the Agent and the Security Trustee specifying their respective
      capacities.

      the US Loan Note Instrument to the contrary.

      the terms of the Fees Letter.

      certificates or otherwise) shall thereupon become a party hereto. Each
      party hereto makes an irrevocable offer in such terms to each such person
      which may be accepted by such person by becoming a Bank or a Bank, without
      the need for any further action. In addition each party hereto (including

      to become a party hereto by the execution of a Transfer Certificate (as
      defined in the Credit Agreement) so as to bind such person to the terms of
      this Agreement as a Bank. The parties hereto agree that this authorisation
