PART I

ITEM 1. DESCRIPTION OF BUSINESS

INTRODUCTION

ADT, through its subsidiaries, is engaged in two service businesses,
electronic security services in North America and Europe and vehicle auction
and related services in the United States.

History of ADT Limited

ADT Limited was incorporated in Bermuda on September 28, 1984 under the name
Hawley Group Limited.  In December 1984, as part of a corporate
reorganization, Hawley Group Limited became the parent company of the Hawley
group of companies.  Prior to this reorganization, the parent company of the
Hawley group of companies was Hawley Group PLC ("Hawley Group"), a company
into which new management had been introduced in 1977, headed by Mr. M.A.
Ashcroft, Chairman and Chief Executive Officer of ADT Limited.  At the time of
the reorganization, the Hawley group of companies had a number of interests in
service and other industries.  ADT Limited became a publicly traded company
under the name Hawley Group Limited on December 24, 1984 when its common
shares were listed for trading on the London Stock Exchange.  Prior to this
date, the ordinary shares of Hawley Group had been listed on the London Stock
Exchange.  Hawley Group Limited changed its name to ADT Limited in 1988 after
its acquisition in 1987 of ADT, Inc.  (now named ADT Security Services, Inc.,
hereinafter "ADT Security Services").  ADT Limited's businesses are conducted
through its subsidiaries.

ADT Limited operates under the Companies Act, 1981 of Bermuda (as amended).

Development of ADT's Electronic Security Services Business

The electronic security services division in North America principally
consists of ADT Security Services, ADT Canada, Inc., Alert Centre, Inc.
("Alert") and API Security, Inc., a subsidiary of Automated Security
(Holdings) PLC ("ASH").  ADT built the core of its North American electronic
security services business by acquiring Electro-Protective Corporation of
America in 1981, the business of Crime Control, Inc., and ADT Security
Services in 1987. Between 1982 and 1985, ADT also acquired several small
security services businesses in North America.  The electronic security
services division in Europe consists of ASH, principally doing business as
Modern Security Systems Limited in the United Kingdom, and Electric Protection
Services Limited doing business as ADT Security Systems in the United Kingdom
("Electric Protection") and other subsidiaries doing business under the ADT
name in continental Europe.  Electric Protection and the principal continental
European subsidiaries were acquired as part of the acquisition of ADT Security
Services in 1987.

                                    1


In 1990, ADT acquired Britannia Security Group PLC
("Britannia"), operating principally in the United Kingdom and, in the third
quarter of 1996 merged with and acquired ASH, which provides electronic
security services in the United Kingdom and North America. In the fourth
quarter of 1995, ADT disposed of its electronic article surveillance business
which was based in Europe and which was previously acquired as part of
Britannia.  Alert, which provides electronic security services in the United
States, was acquired in the fourth quarter of 1995.

Development of ADT's Vehicle Auction Business

ADT's auction division was established in 1987 by the acquisition of The
British Car Auction Group PLC ("BCA") which, at that time, had 14 auction
centers in the United Kingdom and 12 auction centers in the United States.
BCA was established in the United Kingdom in 1946 and, during the period from
1946 to 1982, it expanded its vehicle auction business in the United Kingdom.
In 1982, BCA entered the vehicle auction business in the United States by
acquiring two vehicle auctions.  From 1982 to 1987, BCA acquired and
constructed additional auction sites in both the United States and the United
Kingdom.  Since 1987, the auction division has expanded its vehicle auction
operations by the purchase of eight auction businesses and four auction
centers in the United States, the development and construction of seven new
auction centers and by internal growth.  In the fourth quarter of 1995, ADT
disposed of its vehicle auction businesses in the United Kingdom and
continental Europe, retaining a 10 per cent equity interest. In the United
States, the auction division consists of ADT Automotive Holdings, Inc. and its
subsidiaries (formerly Anglo American Auto Auctions).

Registered and Principal Executive Offices

The registered and principal executive offices of ADT Limited are located at
Cedar House, 41 Cedar Avenue, Hamilton HM 12, Bermuda.  The executive offices
of the subsidiary which supervises ADT's North American activities are located
in the United States at 1750 Clint Moore Road, PO Box 5035, Boca Raton, Florida
33431.  The telephone number there is 561-988-3600.

BUSINESS DESCRIPTION

ADT, through its subsidiaries, is engaged in two service businesses,
electronic security services in North America and Europe and vehicle auction
and related services in the United States. In this business description, the
term "ADT" is used to refer to the relevant operating subsidiary of ADT
Limited engaged in that part of the business being described where the term
appears.

ADT's principal activities in the electronic security services business are
the electronic monitoring and maintenance of its installed base of security
systems and the installation of new, monitored security systems to add to its
installed base.  Monitored systems may be sold or, as is most often the case,
ADT may retain ownership of installed systems.  ADT receives contractual
recurring fees for monitoring security systems through its electronic customer
monitoring centers and for maintenance of security systems installed at
customer premises and other related services.  ADT sells, installs and
maintains monitored security systems, integrated electronic security systems
and other electronic security products for additional fees. Annualized
contractually recurring fees for electronic monitoring and maintenance of
security systems installed at customer premises, and other related services,
as of December 31, 1996, represented approximately 65 per cent of ADT's total
electronic security services revenues in North America and Europe for 1996.
The remainder of ADT's security revenues were derived from the outright sale
and installation of security systems, the installation of security systems in
accordance with monitoring service agreements and the maintenance of security
systems on a non-contractual basis.

                                    2


ADT's vehicle auction business operates a network of large modern auction
centers in the United States which provide an organized wholesale marketplace
for the sale and purchase of used vehicles.  Principal sellers, or consignors,
include new and used vehicle dealers, vehicle manufacturers, fleet operators,
leasing companies, financial institutions and government agencies.  Principal
purchasers include franchise and non-franchise vehicle dealers and
distributors who acquire vehicles to sell in the retail market.

The following table presents the proportion of revenues derived by ADT from
electronic security services and vehicle auction services  in 1995 and 1996.

Electronic Security Services

The Industry

The security services industry encompasses a wide range of products and
services, which can be broadly divided into electronic security products and
services and highly labor intensive manned guarding and patrol services.
ADT's electronic security services division competes primarily in the
comparatively capital intensive electronic monitoring security services sector
of the industry.  Electronic security products and services consist of the
sale, installation, continuous monitoring and maintenance of electronic
security systems for commercial and residential use.  This business utilizes
modern electronic devices installed in customers' businesses and residences to
provide detection of events, such as intrusion or fire, surveillance and
control of access or articles.  Event detection devices may be monitored by
monitoring centers, such as ADT's customer monitoring centers, which are
linked to the customer through telephone lines.  These centers are often
located at remote distances from the customer's premises.  In some instances,
the customer may monitor these devices at its own premises or the devices may
be connected to local fire or police departments.  The products and services
marketed in the electronic security services industry range from residential
systems that provide basic entry and fire protection to sophisticated
commercial systems incorporating closed circuit television systems and access
control.

                                    3


The development of centrally monitored alarm systems began at the turn of the
century and, historically, these systems were considered a relatively
expensive form of security and were purchased primarily by businesses and
affluent individuals.  The industry continued to evolve as telephone networks
spread and technology advanced.  Progress continued steadily until the early
1970's when computer technology and semi-conductor components began to be
incorporated into monitoring systems.  Since then, the development of
telecommunications technology and its application in security systems has
accelerated, and technological advances have increased the availability of
lower cost, sophisticated electronics.  These advances have enabled the
industry to access a wider market by providing a broader range of monitored
security services at a variety of price levels.  Concurrently with these
technological advances, demand for security systems has grown with the
increase in the general awareness of security issues and rising crime rates.
Customers also purchase security systems due to the practice in the insurance
industry of reducing premiums for customers who have a security system
installed, or requiring the installation of a security system as a condition
of coverage.

STAT Resources, Inc., an independent market research firm ("STAT Resources"),
estimates that total United States commercial electronic security systems and
services market revenues and total residential electronic security systems and
services market revenues were approximately $8.0 billion and $5.0 billion,
respectively in 1996.  ADT accounted for approximately 7.7 per cent and 7.5
per cent of these amounts, respectively.  Although a certain amount of
industry consolidation has taken place, the industry in North America remains
highly fragmented and STAT Resources estimates that there were approximately
13,000 companies in the United States electronic security systems and services
market in 1996. The electronic security services industry in Europe is also
highly fragmented.


Business Strategy

ADT[Registered] is a leading name in electronic security services, and ADT
believes that its name is important in the marketing of its security services
and in competing with other electronic security service providers.  Before
1987, ADT's electronic security services business served predominantly
commercial customers.  Since 1987, ADT's goals have been to create a lower
cost, more efficient operation, suitable for long-term growth and greater
profitability, and to take advantage of the economies of scale resulting from
increased utilization of its infrastructure.  Since 1987, ADT has (i) reduced
the number of central stations and equipped its  customer monitoring centers
with enhanced computer technology to further automate the monitoring process
and thus provide increased monitoring capacity, (ii) modernized and
streamlined its computer-based administration and control systems, (iii)
enhanced customer service programs through improved training programs for
sales, management, installation and service employees and (iv) intensively
marketed electronic monitoring services to residential customers to take
greater advantage of the increased monitoring capacity created by the
monitoring center consolidation and modernization program.

Between 1987 and 1993, ADT significantly reduced the number of its central
stations from 162 to 30 in North America and Europe while increasing
monitoring capacity and maintaining geographical coverage. Since then ADT has
continued to pursue its strategy of central station consolidation, although
closures have taken place at a slower rate. Further opportunities for central
station consolidation now exist following the acquisition of ASH. In the first
quarter of 1997, ADT announced that it was investing in planned enhancements
to its technological infrastructure to facilitate a further consolidation of
its monitoring center network in order to provide for future anticipated growth
opportunities while lowering costs and increasing monitoring capacity and
operating efficiency.

As a result of ADT's program implemented in 1988 to target the residential
sector in North America, as well as growth in the level of consumer concern
over crime and security generally and the availability of lower priced
systems, ADT has significantly expanded its residential customer base in North
America.  Since 1988, ADT has enjoyed an annual compound growth rate in
residential unit sales in excess of 36 per cent. ADT believes that because of
the success of its sales and marketing efforts since 1988, it is uniquely
positioned to benefit from the range of technological developments that are
expanding and diversifying the types of services  that ADT is able to offer.

                                    4


During the past several years, ADT's business has been evolving from that of
primarily an intrusion alarm company into a data information company. ADT has,
in the past few years, been offering energy management products and services
to regulate the temperature and lighting in a customer's premises. This
service has been achieved through the use of a communication protocol which
utilizes the premises' existing alternating-current wiring. Another creative
use of new technologies has permitted the launch of CarCop[Registered] which
combines three significant infrastructures, cellular communications, the
global positioning satellite system and ADT's 24 hour monitoring services, to
provide a revolutionary new personal protection and vehicle security service.

ADT believes that its broad customer base, its unique national distribution
system and its highly skilled workforce provide it with a strong capacity to
exploit new technologies and, given the rapid pace of technological change, ADT
anticipates that it will explore partnering opportunities with premier
companies in a variety of industries.

ADT's overall goal is to expand its customer base in both the commercial and
residential sectors.  The commercial sectors in North America, the United
Kingdom and continental Europe represent well established markets with growth
prospects closely related to the overall economic growth in these markets.
ADT's strategy is to retain a high percentage of its existing commercial and
residential customers by continuing to provide high quality service.  As part
of its strategy to maintain and enhance its commercial market position in
North America, ADT has a national accounts sales team in place in the United
States to serve customers that have multiple locations.  ADT believes that the
North American residential marketplace continues to represent a relatively
unpenetrated market and ADT's strategy is to continue to market and install
large numbers of new residential security systems, primarily in this market.
ADT is continuing to implement this strategy through intensive advertising and
marketing in metropolitan areas.  ADT believes that incremental monitoring
revenues from new customers should enhance operating margins because
additional customers can  be served through ADT's existing monitoring
facilities with very little impact on ADT's total operating costs associated
with monitoring security systems. ADT, however, incurs  marketing costs
associated with the sale of new systems and incremental installation costs in
respect of each new system sold which are partly offset by a fee charged to
the customer on installation of the system. In the first quarter of 1997,  ADT
announced that it was investing in planned enhancements to its technological
infrastructure to facilitate monitoring center consolidation and provide
increased capacity for future anticipated growth opportunities.

Consistent with its strategy, ADT acquired Alert in the fourth quarter of 1995
and merged with ASH in the third quarter of 1996 adding, in aggregate, over
375,000 customers to ADT's customer base.  The acquisition of Alert also
provided ADT with an established dealer program under which security systems
are installed by third parties with the monitoring contracts being onsold to
ADT for monitoring.  Such a program represents a cost effective way for ADT to
further enhance its operating leverage. The acquisition of ASH gave ADT
leadership in the electronic security services sector in the United Kingdom
and will provide ADT with a new marketing opportunity in the UK residential
market place.

The following table presents the approximate number of commercial and
residential customers in North America and Europe contracting with ADT for the
monitoring or maintenance of electronic security systems, together with the
aggregate annualized service revenue under contract, as of December 31, 1996,
and the annual combined discontinuance rate for commercial and residential
contracts in respect of 1996.

Commercial

ADT provides electronic security services and products to financial
institutions, industrial and commercial businesses and complexes, warehouses,
facilities of federal, state and local government departments, defense
installations, and health care and educational facilities.  ADT conducts its
commercial operations in the United States, Canada, the United Kingdom, Spain,
France, Belgium, Greece, The Netherlands and the Republic of Ireland.  ADT
sells, installs, monitors and maintains electronic security systems and
products located at its customers' premises.  These systems and products are
tailored to customers' specific needs and include electronic monitoring
services that provide intrusion and fire detection, as well as card or keypad
activated access control systems and closed circuit television systems.  ADT
also markets standard security packages for specific types of commercial
customers, such as retailers and banks.  Certain commercial customers require
more complex electronic security systems.  To meet this demand, ADT also sells
integrated electronic security systems that combine a variety of electronic
security services and products.  These systems are integrated by ADT to
provide a single computer controlled security system.  Integrated security
systems are typically owned by the customer and can range in price from a few
thousand to several million dollars.  Integrated security systems may be
monitored by the customer at its premises or connected to an ADT monitoring
center.  In either case, ADT usually provides support and maintenance for these
systems through service contracts.

The systems installed at commercial customers' premises may be owned by ADT
or, as in the case of most integrated systems, by the customer.  When the
system is sold, the customer pays ADT the purchase price upon installation and
the customer also pays an installation fee.  When monitoring equipment is
owned by ADT, as is most often the case, only an installation fee is charged.
Most customers also agree to pay an annual service charge for monitoring and
maintenance.  Some customers elect to pay for maintenance on a per visit
basis.  Service contracts for integrated security systems are negotiated on an
individual basis.  For integrated systems, a separate fee is charged for
systems integration and installation.  Service contracts are negotiated on an
individual basis depending upon the number of systems monitored, the type of
alarm transmission and the level of response services required.

STAT Resources estimates that total United States commercial electronic
security systems and services market revenues were approximately $8.0 billion
in 1996.  ADT accounted for approximately 7.7 per cent of this amount.

Commercial customers are motivated to purchase security systems to protect
their property, employees and customers and by their insurance carriers which
may offer lower premium rates if a security system is installed or require
that a system be installed as a condition to coverage.  Of those insurance
carriers in North America which offer lower premiums or will provide coverage
only to customers with centrally monitored alarm systems, most require the
monitoring center to be approved by Underwriters Laboratories, Inc.  ("UL").
UL requires each monitoring center to meet specified design, technical and
operational standards, including back up power capability.  UL confirms
compliance with its specifications through periodic on-site inspections.  All
of ADT's customer monitoring centers in the United States are UL approved.

As of December 31, 1996, approximately 478,000 commercial customers, some of
which have multiple locations, were under contract in North America,
approximately 153,000 were under contract in the United Kingdom and
approximately 41,000 were under contract in continental Europe.  The
electronic security services business in Europe services primarily commercial
customers.  In 1996, approximately 68 per cent of ADT's total electronic
security services revenues in North America and Europe were derived from
commercial customers.  The electronic security services division is not
dependent upon any single customer, as the revenue from any one customer does
not exceed one per cent of the division's total net revenues.

Contracts with commercial customers for monitoring and maintenance services
are usually for an initial five-year term, automatically renewing on a
year-to-year basis thereafter, unless canceled.  A substantial number of
contracts are now beyond their initial term and are therefore on an automatic
renewal basis.  It has been ADT's experience that monitoring contracts for
security systems are generally renewed upon their expiration.  Contract
discontinuances, however, do occur, principally as a result of customer
relocation or closure.

ADT markets its electronic security services to commercial customers through a
direct sales force in North America and Europe and through direct mail and
print advertising.  Customers which have multiple locations in North America
are serviced by a separate national accounts sales force.

Residential

Residential electronic security services are primarily marketed to customers
in North America and consist of the sale, installation, monitoring and
maintenance of electronically monitored security systems to detect intrusion
and fire.  Residential customer service and monitoring are performed from the
same facilities as those used for commercial accounts.

STAT Resources estimates that total United States residential electronic
security systems and services market revenues were approximately $5.0 billion
in 1996.  ADT accounted for approximately 7.5 per cent of this amount.

As part of its business strategy, ADT began to intensively market monitored
security systems to residential customers in North America in 1988 and ADT
believes that it has been able to sell a large number of residential security
systems due to the growing level of consumer concern over crime and security
generally and the availability of lower priced systems.  In addition,
residential customers are usually able to obtain more favorable insurance rates
if an electronically monitored security system is installed in their home.
ADT targets two groups of residential customers, those who typically require
relatively inexpensive, standard electronically monitored security systems and
a smaller group of residential customers who require more sophisticated
systems.

In 1996, ADT contracted to install and monitor approximately 280,000 new
residential security systems, principally in North America,  and as of
December 31, 1996, ADT had approximately 1,149,000 residential customers under
contract for monitoring services, of which approximately 90 per cent were
located in North America.  In 1996, approximately 32 per cent of ADT's total
electronic security services revenues in North America and Europe were derived
from residential customers.  On average, fees charged by ADT for residential
monitoring services are lower than the fees charged for commercial monitoring
services.  Contracts for residential services entered into after 1990 have
usually been for an initial three-year term, automatically renewing on a
year-to-year basis thereafter, unless canceled.  For contracts entered into
after April 1992, automatic renewal has been for two-year terms, unless
canceled.  A substantial number of contracts are now beyond their initial term
and are therefore on an automatic renewal basis.  It has been ADT's experience
that residential contracts are generally renewed upon their expiration.
Contract discontinuances, however, do occur, principally as a result of
customers relocating.

In North America, ADT usually retains ownership of standard residential
systems whereas the more sophisticated systems are usually purchased by the
customer.  When the system is sold, the customer pays ADT the purchase price
upon installation and the customer also pays an installation fee.  When the
system is owned by ADT, as is most often the case, only an installation fee is
charged.  Substantially all residential customers agree to pay an annual
service charge for monitoring and may also subscribe for maintenance services.
Uniform package prices are offered to residential customers who purchase ADT's
standard residential security system which includes a fixed number of
detection devices.  Frequently, customers add detection devices to expand the
coverage of the system for which ADT charges an additional installation fee
and an additional sales charge if the system is purchased.  Pricing for
residential customers who require more sophisticated systems depends upon the
monitoring components installed, the type of alarm transmission and other
services required.

ADT markets its electronic security services to residential customers through
television and radio advertising, print advertising, telemarketing, direct
mail and through a direct residential sales force as well as through
approximately 120 independent ADT authorized dealers and through third party
affinity marketing arrangements.

Installation, Service and Maintenance

As part of its effort to provide high quality service to its commercial and
residential customers, ADT maintains a trained installation, service and
maintenance force of in North America and Europe. These employees are trained
by ADT to install and service the various types of commercial and residential
security systems which are marketed by ADT.  ADT also uses sub-contracted
personnel where appropriate.

                                    7


Product Sourcing

ADT does not manufacture any of the components used in its electronic security
services business, although it does provide its own specifications to
manufacturers for certain security system components and undertakes some final
assembly work in respect of more sophisticated systems.  Due to the general
availability of the components used in its electronic security services
business, ADT believes that it is not consistent with its role as a services
company to be involved in manufacturing.  This policy allows ADT to obtain the
components of its systems from a number of different sources and, by so doing,
to supply its customers with the latest technology generally available in the
industry.  ADT is not dependent on any single source for its supplies and
components and has not experienced any material shortages of components.

Monitored Electronic Security Systems

ADT's electronically monitored security systems involve the use on a
customer's premises of devices designed to detect or react to various
occurrences or conditions, such as intrusions, movement, fire, smoke, flooding,
environmental conditions (including temperature or humidity variations),
industrial operations (such as water, gas or steam pressure and process flow
controls) and other hazards.  In most systems, these detection devices are
connected to a microprocessor based control panel which communicates through
telephone lines to an ADT monitoring center where alarm and supervisory
signals are received and recorded.  Systems may also incorporate an emergency
"panic button", which when pushed causes the control panel to transmit an
alarm signal that takes priority over other alarm signals.  In most systems,
control panels can identify the nature of the alarm and the areas within a
building where the sensor was activated and transmit the information to an ADT
customer monitoring center.  Depending upon the type of service for which the
subscriber has contracted, monitoring center personnel respond to alarms by
relaying appropriate information to the local fire or police departments,
notifying the customer or taking other appropriate action, such as dispatching
employees to the customer's premises.

In most systems, the control panel communicates with an ADT customer
monitoring center through one of four telephone line transmission systems,
direct wire, multiplex, digital communicator or derived channel.  Direct wire
and multiplex systems are used mainly for commercial customers who require a
higher level of security, whereas digital communicator or derived channel
systems are used primarily in systems where cost is more important.  Direct
wire transmission uses a dedicated leased telephone line and is the most
expensive form of monitoring connection.  The multiplex system uses a remote
device to receive signals from multiple customers' premises and concentrate
and retransmit them over a dedicated leased telephone line to an ADT customer
monitoring center.  These two transmission methods allow ADT to continuously
monitor the customer's security system to confirm that the connection to the
monitoring center is functioning properly.  The multiplex system provides the
same level of security as direct wire but is less costly due to the reduced
number of dedicated telephone lines which are necessary to monitor the same
number of customers.  ADT has a continuing selective conversion program to
replace direct wire transmission systems with lower cost multiplex or digital
systems.  These conversions typically replace older equipment and result in a
reduction in telephone line costs and in the frequency of customer service
calls.

A security system which utilizes a digital communicator responds to an event
by dialing the monitoring center through the customer's regular telephone
line.  Unlike multiplex and direct wire systems, these systems are not
continuously monitored, and if a control panel or the telephone line is not
functioning properly the monitoring center may not be alerted.  The derived
channel system, which is not available in all markets, ties into the existing
regular telephone line network but allows parallel simultaneous communication
on one line using separate distinct frequencies.  Using the derived channel
system, it is possible to continuously monitor a digital communicator
connection over the customer's regular telephone line.  In certain markets ADT
also offers systems with backup transmission capability through radio
frequency transmission or the local cellular telephone network.

                                    8


Other Security Businesses

ADT entered the mobile security services market in 1996 with the launch of
CarCop[Registered], a vehicle security system introduced in the fourth quarter
of 1996 in conjunction with Mobile Security Communications, Inc. which is
responsible for the sale and installation of the CarCop product. CarCop
combines ADT's 24 hour monitoring services with cellular communications
technology and the Global Positioning Satellite system to provide constant
security coverage for a vehicle and its occupants whether the vehicle is
parked, unattended or in use. The system can detect a range of emergency
situations and, through utilizing ADT's 24 hour monitoring services and
employing satellite tracking technology, the appropriate assistance can be
despatched to the vehicle's exact location at any time, day or night.

Competition

The electronic security services business in North America is highly
competitive.  New competitors, who have not necessarily had any previous
involvement in the provision of electronic security services, are continually
entering the field.  Competition is based primarily on price in relation to
quality of service.  ADT believes that the quality of its services is higher
than that of many of its competitors.  Accordingly, ADT's prices may therefore
be higher than those charged by many of its competitors.  Sources of
competition in the security services business are other providers of central
monitoring services, systems directly connected to police and fire
departments, local alarm systems and other methods of protection, such as
manned guarding.  ADT believes the number of local police and fire departments
that perform monitoring has been declining for some years.

The central monitoring sector of the electronic security services business is
characterized by high fixed costs but has low marginal costs associated with
monitoring additional customers.  Opportunities exist within the industry  to
achieve economies of scale by consolidation of monitoring and administrative
functions and a certain amount of industry consolidation is currently taking
place. The industry in both North America and Europe, however, remains highly
fragmented.  ADT believes that it services more customers through its customer
monitoring centers in North America than any other company.  Individual
competitors, however, may service more customers in a given local market.

ADT competes with other major firms in North America, which have substantial
financial resources, including Ameritech Corporation (operating under the
SecurityLink from Ameritech[Registered] brand name);  Borg-Warner Security
Corporation (operating under the Wells Fargo[Registered] and Pony
Express[Registered] brand names); the Honeywell Protection Services division
of Honeywell, Inc.; the Brink's Home Security division of The Pittston
Company; and approximately 13,000 smaller regional and local companies.  ADT
also competes with several national companies and several thousand regional
and local companies in the United Kingdom and continental Europe.

In February 1996, a federal telecommunications reform bill was enacted which
contained provisions specific to the electronic security services industry.
Ameritech Corporation was prohibited from acquiring additional equity or
financial interests in alarm monitoring companies for five years from the date
of enactment of the law and the other regional Bell operating companies are
barred from acquiring more than a 10 per cent equity interest in alarm
monitoring companies or otherwise entering the business for five years from
the same date.
                                    9


Regulation

ADT's operations are subject to a variety of federal, state, county and
municipal laws, regulations and licensing requirements in the United States
and national and local government laws, regulations and licensing requirements
in countries outside the United States.  Many of the states and countries in
which ADT operates, as well as certain local authorities, require ADT to
obtain licenses or permits to conduct its security services business.  Certain
governmental entities also require persons engaged in the alarm business to be
licensed and to meet certain standards in the selection and training of
employees and in the conduct of business.  ADT believes that it is in
substantial compliance with all such licensing and regulatory requirements in
each jurisdiction in which it operates.  In addition, there has been a trend
recently on the part of municipalities and other localities to attempt to
reduce the level of false alarms through various measures such as the
licensing of individual alarm systems and the imposition of fines upon
customers, revocation of licenses or non-response to alarms after a certain
number of false alarms.  While such statutes and ordinances have not had a
material adverse affect on ADT's business operations to date, ADT is unable
to predict whether such statutes or ordinances, or any similar statutes or
ordinances enacted by other jurisdictions, will adversely affect ADT's
business and operations in the future.  The alarm industry is also subject to
the oversight and requirements of various insurance, approval, listing and
standards organizations.  Adherence to the standards and requirements of such
organizations may be mandatory or voluntary depending upon the type of
customer served, the nature of security service provided and the requirements
of the local governmental jurisdiction.  ADT has not had any material
difficulties in complying with such standards and requirements in the past.

ADT's electronic security business relies upon the use of telephone lines to
transmit signals, and the cost of such lines and the type of equipment which
may be utilized are currently regulated by both the federal and state
governments in the United States and national and local governments in other
countries.

Risk Management

The nature of the services provided by ADT potentially exposes it to greater
risks of liability for employee acts or omissions or product liability than
may be inherent in many other service businesses.  To attempt to reduce this
risk, ADT's electronic security service contracts contain provisions limiting
its liability and requiring indemnification by its customers.  ADT also
carries insurance of various types, including general liability and errors and
omissions insurance, to protect it from product defects and negligent acts of
its employees.  ADT obtains such insurance at rates and upon terms negotiated
periodically with various underwriters.  The loss experience of ADT and, to
some extent, other security services companies, may affect premium rates
charged to ADT.  As of December 31, 1996 such policies provided that ADT
retain liability for the first $1.0 million per occurrence.  Certain of ADT's
insurance policies and the laws of some states may limit or prohibit insurance
coverage for punitive or certain other kinds of damages arising from employee
misconduct.  In addition, in some states ADT's limitation of liability clause
may be ineffective in cases of gross negligence and in certain other
situations.


Patents and Trademarks

ADT Security Services holds approximately 40 active patents worldwide and has
several pending patent applications.  No patents are due to expire in the near
future that would materially affect the operations of ADT's electronic
security services business.  The ADT[Registered] trademark and service mark
are important to ADT's electronic security business.  ADT Security Services
uses several other trademarks and service marks in marketing its products and
services,including Focus[Registered], Centrascan[Registered],
Safewatch[Registered] and Customer Link[Registered] .  ADT believes that the
rights in these trademarks and service marks, including Focus, Centrascan,
Safewatch and the ADT trademark are adequately protected.

Employees

As of December 31, 1996, the electronic security services division had
approximately 16,000 employees,  of whom approximately 12,000 were based in
North America and approximately 4,000 were based in Europe.  The majority of
these employees are not represented by unions or covered by collective
bargaining agreements.  ADT believes its relations with employees and their
unions are generally good.

Vehicle Auction Services

The Industry

Vehicle auctions constitute a principal channel of distribution and
redistribution for used vehicles.  An auction brings together, in one
location, dealers seeking to restock and diversify their inventory of used
cars with a high volume of various makes and models provided by sellers
seeking to dispose of their vehicles.  The vehicle auction industry provides a
reliable marketplace where many dealers participate in the auction's bid
process and thus establish true wholesale prices for used vehicles. Vehicle
auctions are preferred by many dealers, financial institutions and other
sellers because an auction provides an efficient, cost-effective and
convenient method of vehicle resale at the prevailing market price.

The principal sources of vehicles for sale through auctions are consignments
by new and used vehicle dealers, vehicle manufacturers, corporate owners of
vehicles such as fleet operators, daily rental companies, leasing companies,
banks and other financial institutions, manufacturers' credit subsidiaries and
government agencies.  The vehicles consigned by dealers include vehicles of
all types and ages and include vehicles that have been traded in against new
car sales.  Vehicles consigned by corporate and financial owners include both
repossessed and off-lease vehicles and, as a result, are normally in the range
of one to four years old. The principal purchasers of vehicles at ADT's
auctions are new and used vehicle dealers and distributors.

ADT believes that the consignment of vehicles from dealers is the foundation
of the auction industry. Dealers rely on the sale of used vehicles for a
significant proportion of their profits and are both buyers and sellers at
auction.

A significant number of vehicles sold at auction in recent years has been
attributable to vehicles being disposed of by domestic and import
manufacturers who contract with certain auctions to sell used vehicles on
their behalf. In the late 1980's, vehicle manufacturers found it advantageous
to produce more vehicles than were necessary to satisfy immediate retail
demand.  These vehicles were either sold to daily rental car companies with a
guarantee by such manufacturers to repurchase the vehicles or were leased to
the daily rental car companies ("Program Cars").  Upon repurchase, the vehicle
manufacturers chose to remarket these late-model cars to their dealers
primarily through the vehicle auction network.  Program Car auctions are
restricted to each manufacturer's franchised dealers with the exception of
auctions for some small volume import manufacturers.  According to industry
sources, the number of vehicles coming to auction from this source reached a
peak of 1.6 million units in 1991. As the industry came out of recession in
1992, volumes reduced and have stabilized at around 1.1 million vehicles per
year. When the number of cars available to daily rental companies through
manufacturers' guaranteed repurchase programs was at its peak, many of the top
rental companies obtained large numbers of their vehicles through such
programs. As manufacturers have reduced their buy back programs , the daily
rental companies have been obliged to purchase more vehicles in their own
names and, consequently, their need  to remarket vehicles at the end of their
life cycle has increased.

Vehicles owned by corporations and financial institutions represent another
major source of vehicles for sale at auction and include vehicles owned by
daily rental companies, vehicles from company fleets, end of term or early
termination vehicles from leasing companies, including manufacturers' finance
subsidiaries, vehicles from finance companies, including repossessed vehicles,
and vehicles from the public sector. The dynamics of this segment are
changing, particularly as the trend towards leasing new vehicles by
individuals under manufacturers' lease programs increases.

ADT Auctions

As of December 31, 1996, ADT operated 27 vehicle auction centers in the United
States where it is the second largest provider of vehicle auction services.
In 1996 the aggregate value of vehicles sold through ADT auction centers was
approximately $8.7 billion.  Substantially all of the vehicles sold at ADT
auction centers are passenger cars and light trucks with the balance
consisting of heavy trucks and industrial vehicles.

                                    11


The following table presents the approximate number of vehicles entered and
sold through all of ADT's vehicle auction centers in the United States during
1994, 1995 and 1996.


                                 1994           1995           1996

Business Strategy

ADT has been a leader in developing the wholesale vehicle auction business in
the United States.  ADT aims to provide a wholesale redistribution system for
used vehicles which is efficient, economical and reliable.  ADT's specific
strategies are (i) to maintain and further strengthen its current
relationships with vehicle manufacturers, fleet/lease operators, daily rental
companies  and other significant vehicle suppliers and dealers that both supply
vehicles for auction and purchase vehicles at auction and (ii) to increase
ADT's share of total used vehicle transactions.  ADT is pursuing these
strategies in part by encouraging more vehicle dealers to attend its auctions.

Where possible, ADT categorizes its auction sales in order to facilitate the
matching of appropriate buyers with vehicles being offered for sale.  Auctions
may be categorized by the type of vehicle being sold or by age of vehicle,
mileage or source, for example ex-rental vehicles.  ADT maintains a record of
dealers that are authorized to bid at its auctions and employs direct
marketing techniques to target dealers who are known buyers for the category of
vehicle being auctioned and who are registered with ADT as approved buyers.
ADT also holds closed sales for manufacturers' vehicles, including Program
Cars and fleet vehicles, restricted to dealers holding a franchise from that
particular manufacturer.

ADT keeps its site location strategy and real estate requirements under
continuous review together with the potential benefits of expanding its
network through the acquisition of vehicle auction businesses and the
development of new auction centers.  ADT however believes that the geographic
coverage of its auction network in the United States is substantially
complete.

Auction Operations

ADT operates a network of large modern auction centers and provides a
comprehensive range of vehicle redistribution services.  These services
include collection and transportation of a seller's vehicles to an auction
center, reconditioning the vehicles to retail standards, matching the vehicles
with the auction market most likely to generate the highest amount of sale
proceeds and delivering the vehicles to the buyer.  Separate fees are charged
for each of these services.  ADT acts solely as an agent in auction
transactions and does not purchase vehicles for its own account.  ADT
repurchases a small number of vehicles under its buyer protection programs
which require it to repurchase vehicles that have suffered odometer tampering
or that have an undisclosed salvage history.  See "Vehicle Auction
Services-Services and Fees-Insurance." ADT operates almost exclusively in the
wholesale marketplace.  In general, the public is not permitted to attend
auctions.

When a vehicle arrives at an ADT auction center, it is checked in and assigned
a computer tracking number.  A seller may instruct ADT to perform various
services including vehicle appraisal, appearance reconditioning and paint or
body work to prepare the vehicle for auction.  The title is checked against a
computer database held by ADT.  If a salvage history appears, the seller must
either disclose the damage or withdraw the vehicle from the auction.  ADT
completes all requested services and holds the vehicles in secure parking
areas until the scheduled auction day.  The auction centers use computerized
control systems to track vehicles through each step of the auction process.
ADT is responsible for the vehicles while they are under its control.

                                    12


Generally, ADT's auction centers hold regularly scheduled auctions for
vehicles from specific market sources.  Additional auctions are scheduled as
necessary, including auctions for specific types or categories of vehicles,
such as heavy trucks, municipal and agricultural equipment and classic cars. A
typical auction center consists of an auction hall, large paved areas for the
storage of vehicles, facilities for reconditioning and separate areas for
parking vehicles immediately prior to auction, some of which are covered.
Auction halls typically have a number of lanes through which vehicles are
normally driven, and where the auction bidding process takes place. This is a
continuous process that enables a large number of vehicles to be auctioned
quickly and efficiently.  The auction hall building also contains the cashiers
and other administrative personnel, as well as cafeteria and other customer
facilities.  When a vehicle is sold, the paperwork associated with a sale,
including conveyance instruments, title or title applications and tag
applications, is generally processed within one hour of the sale and immediate
delivery arrangements are made.  A particular vehicle may pass through the
auction system more than once prior to being sold to a new owner.

ADT is responsible for payment to sellers upon presentation of title after a
vehicle is sold.  If purchases are made other than on a cash basis, ADT
determines in advance the credit-worthiness of the buyer.  It is customary for
buyers at ADT's auctions to pay by banker's draft.  The auction collects funds
on drafts within an average of ten working days.  ADT's bad debt experience on
these transactions is negligible.

Sources of Vehicles

The principal sources of vehicles for sale at ADT's auctions are consignments
by new and used vehicle dealers, vehicle manufacturers, corporate owners such
as fleet operators, daily rental companies, leasing companies, banks and other
financial institutions, manufacturers' credit subsidiaries and government
agencies.

The supply of consignment vehicles from dealers is relatively constant
throughout the year.  The number of Program Cars and vehicles consigned to
auction by corporate fleet owners may fluctuate considerably throughout the
year.  As a consequence, auction revenues may fluctuate from quarter to
quarter and at certain times during the year ADT may be storing large numbers
of vehicles awaiting auction.

ADT contracts with vehicle manufacturers for the auction of Program Cars.
These contracts, which do not require the manufacturers to sell any minimum
number of vehicles through ADT's auctions, generally have a term of one year
and may be terminated upon 30 days' notice.  In 1996, approximately 27 per
cent of the vehicles sold at ADT auctions were Program Cars, compared to
approximately 31 per cent in 1995.  ADT also auctions vehicles from the
manufacturers' own fleets and from manufacturers' affiliates such as their
credit subsidiaries.

During 1996, General Motors Corporation and its credit subsidiaries accounted
for approximately 8 per cent of the vehicle auction division's United States
revenues.  ADT believes that its relationship with General Motors Corporation
and the other vehicle manufacturers with which it does business is good.  The
loss of General Motors Corporation's business would, however, have a material
adverse effect on the auction division's operations.


Services and Fees

Auction Services: ADT receives a variety of fees for its auction services.
Entry fees are set charges assessed on the majority of vehicles registered for
auction, except Program Cars, and are payable irrespective of whether the
vehicle is sold.  If the vehicle is sold, ADT also receives an auction fee
from the seller and a fee from the buyer of the vehicle.  At most sales, the
buyer's auction fee is based upon the sale price of the vehicle, except for
Program Cars where a fixed fee is charged.  At most sales, other than
fleet/lease consignment sales and Program Car sales, the seller's auction fee
is based on the sale price of the vehicle.  For fleet/lease consignment sales,
the seller's auction fees are based on a fixed fee for national fleet/lease
consignors and on the sale price of the vehicle for local fleet/lease
consignors.  For sales of Program Cars, auction fees are fixed periodically by
agreement with the vehicle manufacturers on a per vehicle sold basis.

                                    13


Reconditioning Services: Customers may request ADT to prepare, for a fee, a
detailed condition report on vehicles entered for auction.  For a separate
fee, ADT also performs on-site reconditioning services.  The largest portion
of reconditioning revenue relates to appearance reconditioning and paint and
body work but more extensive body work services including body panel painting
and repair of minor collision damage are also carried out.  Appearance
reconditioning services include engine steam-cleaning, washing, detailing,
buffing and waxing, and upholstery cleaning.  Other services at certain
centers include replacement of parts, upholstery, tires and glass.

Most manufacturers' vehicles and some fleet/lease vehicles receive appearance
reconditioning and, if necessary, paint and body work.  The reconditioning of
manufacturers' Program Cars generates a significant portion of ADT's
reconditioning revenues.  Program Cars are delivered to the auction centers
directly from rental car lots or marshaling yards, financial institutions
deliver vehicles directly off-lease or after repossession and fleet operators
deliver vehicles immediately from use.  These vehicles generally require
reconditioning to bring them up to sale standards.  In many instances, these
sellers do not have the facilities necessary to recondition the vehicles
expediently or economically.  ADT does not usually recondition vehicles
consigned by dealers, who generally bring fully serviced cars to auction
directly from their lots.  Dealers who purchase reconditioned vehicles are
able to place them in their showrooms or lots immediately, thereby minimizing
the time between purchase and retail sale.

ADT also provides high quality vehicle paint and body repair services under
the Quality Image Services name for vehicles other than those going through
the auction process, principally for fleet owners and insurance companies.
The service, which is aimed at new customers in addition to traditional
auction customers, utilizes ADT's existing reconditioning facilities and
expertise.

Transportation Services: ADT collects and delivers customers' vehicles and
believes that its ability to provide transportation services at competitive
prices is extremely valuable to its marketing efforts.  ADT operates a fleet
of vehicle transporters and sub-contracts any additional vehicle
transportation requirements that cannot be met by this fleet.

Insurance: ADT offers, for a fee, a 15-day power and drive train service
contract provided by a third party.  ADT also undertakes to repurchase
vehicles that have suffered odometer tampering or have an undisclosed prior
salvage history.  ADT also assists sellers in complying with laws regarding
title and odometer readings by providing forms which include the necessary
representations as part of the paperwork signed and delivered in connection
with the auction sale.  ADT's liability for losses arising from title and
odometer insurance, power and drive train service contracts and prior salvage
history has been negligible.

Valuation and Appraisal: ADT provides valuation and appraisal advice to
customers in connection with their vehicle disposal programs with a view to
assisting its customers to obtain the best possible price for their vehicles.

Specialized Services: Specialized auctions carried out by the division include
sales of government vehicles, to which the general public is invited, sales of
plant and equipment, sales of construction vehicles, sales of heavy trucks,
sales of municipal and agricultural equipment and sales of classic cars.  ADT
provides a vehicle repossession service whereby vehicles are recovered from a
defaulting party and delivered directly to an auction center for liquidation.
ADT's market expertise allows it to offer a comprehensive vehicle remarketing
service to fleet operators, ranging from collection of vehicles leaving the
fleet to advice on vehicle replacement cycles.

Competition

ADT considers its competition to be two other significant auction chains and a
large number of independently owned local auctions which are members of the
National Auto Auction Association. The competing auction chains are Manheim
Auctions, a subsidiary of Cox Broadcasting Company, and ADESA Corporation, a
subsidiary of Minnesota Power & Light Company.  Competition is based primarily
on price in relation to the quality and range of services offered to sellers
and buyers of vehicles and ease of accessibility of auction locations.  ADT
believes it provides a higher quality of service than its competitors and its
prices may therefore be higher.

                                    14


Regulation

Each auction center is licensed by the state in which it is located, in most
cases as a vehicle auction or dealer.  These licensing authorities may revoke
a license if an auction is not conducted according to regulations then in
effect.  In addition, ADT's vehicle transportation fleet is regulated by the
Interstate Commerce Commission.  ADT believes that it is in substantial
compliance with the regulations to which it is subject and has not had any
material difficulties with these regulatory authorities.

Employees

As of December 31, 1996, the vehicle auction division in the United States
employed approximately 3,900 persons on a full-time basis and approximately
2,400 persons on a part-time basis.  The part-time employees are utilized
primarily on auction sale days.  The majority of these employees are not
represented by unions or covered by collective bargaining agreements.  ADT
believes its relations with employees and their unions are generally good.

ITEM 2. DESCRIPTION OF PROPERTIES

In North America, as of December 31, 1996, ADT, through its subsidiaries,
owned 2 customer monitoring centers, leased 19 customer monitoring centers,
owned 22 offices and other properties and leased 315 offices and other
properties which were used in connection with the electronic security services
business.  In the United States, as of December 31, 1996, ADT, through its
subsidiaries, owned 21 auction centers, leased 6 auction centers and owned or
leased 6 offices and other properties, which were used in connection with the
vehicle auction business.  In Europe, as of December 31, 1996, ADT, through
its subsidiaries, owned 5 customer monitoring centers, leased 8 customer
monitoring centers, owned 11 offices and other properties and leased 107
offices and other properties which were used in connection with the electronic
security services business.  In addition, as of December 31, 1996, ADT,
through its subsidiaries, owned approximately 1,294 acres of land and leased

ITEM 3. LEGAL PROCEEDINGS

On December 27, 1996, Westar Capital, Inc. ("WCI") filed a complaint in the
U.S. District Court for the Southern District of Florida (the "Court") against
the Company, the directors of the Company and Republic Industries, Inc.
("Republic").  The complaint alleges that the Company and its directors
breached their fiduciary duties to WCI and the Company's other shareholders
(i) by issuing to Republic a share purchase warrant for 15,000,000 Common
Shares (the "Republic Warrant") in connection with a proposed amalgamation
with Republic in July 1996 (the "Republic Merger"), (ii) by adopting the
Rights Plan, and (iii) by holding shares of the Company in one of the
Company's subsidiaries with the intention of voting those shares as needed to
entrench existing management.  The complaint seeks a court order (i) declaring
the Republic Warrant null and void or preventing the Company and Republic from
exercising their rights under the Republic Warrant, (ii) directing the Company
to redeem the Rights Plan, and (iii) preventing the Company from voting the
shares held by its subsidiary.

On January 3, 1997, WCI filed an amended complaint which, in addition to the
allegations made in the prior complaints, alleges that the Company and its
directors have attempted to interfere with WCI's voting rights by seeking
certain information from WCI pursuant to procedures established in the
Company's Bye-Laws.  The amended complaint seeks the same relief as the prior
complaint and also requests that the Court confirm WCI's voting rights.

On January 21, 1997, the Court granted WCI leave to file a second amended
complaint.  The second amended complaint contains the same allegations as the
amended complaint and in addition alleges (i) that the Company and its
directors breached their fiduciary duties by setting a July 8, 1997 date for a
meeting of the Company's shareholders, and (ii) that the Company and its
directors violated Section 14(d) of the Securities Exchange Act of 1934, as
amended, by making a recommendation to the Company's shareholders regarding
the tender offer without first making certain filings with the Securities and
Exchange Commission ("SEC").  WCI asks for a court order (i) enjoining the
Company from holding the shareholders meeting (the "Special General Meeting")
on July 8, 1997, (ii) compelling the Company to hold the special General
Meeting on or before March 20, 1997, and (iii) declaring that the Company has
violated Section 14(d) and enjoining the Company from making any further
recommendations relating to the tender offer until the required SEC filings
are made.

On January 23, 1997, WCI filed a motion for a preliminary injunction asking
the Court to enjoin the Company from holding the Special General Meeting on
July 8, 1997, and compelling the Company to hold the Special General Meeting
on or before March 20, 1997.  On March 4, 1997, WCI filed a supplemental brief
in support of its motion for a preliminary injunction representing that WCI is
no longer seeking a Special General Meeting on or before March 20, 1997 on the
grounds that such a meeting date would now be impractical.  In its
supplemental brief, WCI requests that the meeting date be set 30 days after
its proxy materials for the Special General Meeting are distributed.  As of
this date, the Court has not rendered any decision with respect to plaintiff's
motion for a preliminary injunction.

On January 27, 1997, the Company and its directors filed a motion to dismiss
the second amended complaint based on, among other things, the Court's lack of
personal jurisdiction over the Company and its directors and for failure to
state a claim upon which relief can be granted.  WCI has filed papers in
opposition to the motion.   On February 21, 997, the Court entered an order
ruling that the second amended complaint did not adequately plead personal
jurisdiction over the ADT defendants.  On February 27, 1997, WCI filed a third
amended complaint.  The third amended complaint contains the same allegations
as the second amended complaint and contains additional allegations relating
to personal jurisdiction.

                                    16


On March 11, 1997, the court granted WCI leave to file a fourth amended
complaint.  The fourth amended complaint contains the same allegations as
those in the third amended complaint as well as additional allegations
relating to the Amendment to the Rights Plan implemented by the Company on
March 3, 1997.  In addition to the relief previously requested, the fourth
amended complaint seeks judicial nullification of the Amendment to the Rights
Plan and a rescission of actions by ADT if it is shown that a subsidiary of
ADT cast decisive votes as a shareholder with respect to those actions.

On March 17, 1997, the Company and its directors filed a motion to dismiss the
fourth amended complaint based on, among other things, the Court's lack of
personal jurisdiction over the Company and its directors and for failure to
state a claim upon which relief can be granted.

The Company and the Board believe that the allegations in the WCI's fourth
amended complaint are without merit and intend to vigorously defend against
them.

On March 24, 1997, WCI filed a motion for a preliminary injunction (i)
preventing Republic from selling or transferring any of the warrant shares
it currently owns, and (ii) preventing the Chairman of ADT from exercising the
proxy on the warrant shares.  The Company and the Board have yet to respond
to this motion.

On December 26, 1996, Charles Gachot filed a complaint in the Circuit Court
for the Fifteenth Judicial Circuit in Palm Beach County, Florida against the
Company, certain of its directors, Western and WCI.  The complaint was brought
on behalf of a class of all shareholders of the Company and alleges that
Western and WCI have breached their fiduciary duties to the Company's
shareholders by offering an inadequate price for the outstanding Common
Shares.  The complaint seeks to enjoin Western and WCI from acquiring the
outstanding Common Shares.  The complaint also alleges that the Company and
its directors have refused to negotiate with Western and WCI and that the
Republic Warrant and the Rights Plan are improper.  The complaint seeks
unspecified monetary relief from all defendants.  The Company and the Board
believe that the allegations in Gachot's complaint against the Company and the
directors are without merit and intend to vigorously defend against them.

On February 7, 1997, ADT Operations, Inc. ("ADT Operations"), a subsidiary of
ADT, filed a complaint in the Supreme Court of the State of New York, County
of New York against The Chase Manhattan Bank, N.A. ("Chase").  The complaint
states that Chase has been an important lender and financial advisor to ADT
Operations since 1993, and that in the course of this business relationship,
ADT Operations has disclosed confidential business information to Chase.  The
complaint asserts that ADT Operations and Chase expressly agreed that Chase
would not aid any third party in a hostile takeover bid for ADT.  The
complaint alleges that Chase is currently aiding Western in its attempt to
take control of ADT and that Chase's actions constitute:  (i)  a breach of an
express agreement between Chase and ADT Operations; (ii) a breach of the
implied covenant of good faith that is part of the express agreement between
Chase and ADT Operations; and (iii) a breach of the fiduciary duties that Chase
owes to ADT Operations.  The complaint seeks $50 million in monetary damages.
The complaint also seeks to enjoin Chase from advising, funding, or
participating in Western's attempts to take control of ADT and from disclosing
any confidential information regarding ADT Operations and ADT.  On March 3,
1997, Chase filed a motion for dismissal of ADT Operations' complaint or,
alternatively, summary judgment.  This motion is scheduled to be heard on
April 11, 1997.

On February 7, 1997, ADT Operations filed a motion for a preliminary
injunction, seeking to enjoin Chase from:  (i) advising, funding, or assisting
Western in its efforts to take over ADT or participating in these efforts; and
(ii) using or disclosing any confidential information that ADT Operations
provided to Chase.  The motion was argued before the Court on February 24,
1997 and is currently pending.

On March 11, 1997, Crandon Capital Partners ("CCP") filed a complaint in the
Circuit Court for the Fifteenth Judicial Circuit in Palm Beach County, Florida
against the Company, certain of its current and former directors, and
Republic.  The complaint was brought by CCP in a derivative capacity on behalf
of ADT.  The complaint alleges that ADT's directors breached their fiduciary
duties and wasted corporate assets in connection with (i) the granting of
options to certain officers of ADT in 1996, (ii) the issuance of the Republic
Warrant, (iii) the implementation of the Rights Plan, and (iv) harassing and
attempting to disenfranchise WCI.  The complaint seeks an unspecified amount
of damages and a court order directing ADT's directors to establish a system
of internal controls to prevent repetition of the alleged breaches of
fiduciary duty and corporate waste.

The Company and its directors believe  that the allegations in the complaint
brought by CCP are without merit and intend to vigorously defend against them.

                                    17


ADT Limited and various of its subsidiaries are defendants in a number of
other pending legal proceedings incidental to present and former operations,
acquisitions and dispositions.  ADT does not expect that the outcome of these
proceedings, either individually or in the aggregate, will have a material
adverse effect upon ADT's consolidated results of operations and cash flows or
its consolidated financial position.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

No matters were submitted to a vote of security holders during the last

      First Quarter to March 24                          27 5/8    21 1/4

At March 24, 1997, 156,696,447 Common Shares were held of record by 15,749
record holders.  Since a number of the Common Shares were held by brokers
or other nominees, the number of record holders may not be representative
of the number of beneficial holders.  A subsidiary of ADT Limited owns
3,182,787 Common Shares which are included in the number outstanding.

Dividends

ADT Limited has not declared any dividends on the Common Shares since April
1991.  ADT Limited has no present intention to pay any dividends on the Common
Shares but will keep its dividend policy under review in the light of
prevailing circumstances.  Under the terms of the senior notes and revolving
bank credit agreement ADT Limited may not declare, pay or make any dividend or
distribution with respect to its Common Shares, except in certain defined
circumstances (see "Management's Discussion and Analysis of Financial
Condition and Results of Operations - Liquidity and Capital Resources").

                                    19


Exchange Controls and Other Limitations Affecting Security Holders

ADT Limited has been designated as a non-resident for exchange control
purposes by the Bermuda Monetary Authority, Foreign Exchange Control.  There
are no limitations on the rights of non-Bermuda owners of the Common Shares
arising out of such designation to hold or vote their shares.  Because ADT
Limited has been designated as a non-resident for Bermuda exchange control
purposes, there are no exchange control restrictions on its ability to
transfer funds in and out of Bermuda or to pay dividends to United States
residents who are holders of the Common Shares, except that ADT Limited may
not hold Bermuda dollars except external Bermuda dollars.

The transfer of Common Shares already issued between persons regarded as
resident outside Bermuda for exchange control purposes and the issue of Common
Shares for which consent has already been granted to such persons, may be
effected without specific consent under the Exchange Control Act of 1972 and
regulations thereunder.  All further issues of Common Shares and any transfers
of Common Shares involving any person regarded as resident in Bermuda for
exchange control purposes require specific prior approval under the Exchange
Control Act of 1972.

In accordance with Bermuda law, share certificates are only issued in the
names of corporations, partnerships or individuals.  In the case of an
applicant acting in a special capacity (for example, as an executor or
trustee), certificates may, at the request of the applicant, record the
capacity in which the applicant is acting.  Notwithstanding the recording of
any such special capacity, ADT Limited is not bound to investigate or incur any
responsibility in respect of the proper administration of any such estate or
trust.

Shares purchased for those under 21 years of age must be registered in the
name of the parent or guardian but may be designated with the minor's initials
for the purpose of identification.  ADT Limited will take no notice of any
trust applicable to the shares represented by such certificates.

As an "exempted company", ADT Limited is exempt from Bermuda laws which
restrict the percentage of share capital that may be held by non-residents of
Bermuda, but as an exempted company ADT Limited may not participate in certain
business transactions, including (i) the acquisition or holding of land in
Bermuda (other than that required for its business and held by way of lease or
tenancy for terms of not more than 21 years) without the express authorization
of the Bermuda legislature or the Minister of Finance; (ii) the taking of
mortgages on land in Bermuda to secure an amount in excess of $50,000; (iii)
the acquisition of securities created or issued by, or any interest in, any
local company or business, other than certain types of Bermuda Government
securities or securities of another "exempted" company, partnership or any
other corporation resident in Bermuda but incorporated abroad; or (iv) the
carrying on of business of any kind in Bermuda, except as necessary in
furtherance of the business of the ADT Limited carried on outside Bermuda or
under a license granted by the Minister of Finance of Bermuda.

Under current Bermuda law, no Bermuda withholding tax will be imposed upon
payment of dividends by ADT Limited to its common shareholders.  Furthermore,
ADT Limited has received from the Minister of Finance of Bermuda, under the
Exempted Undertakings Tax Protection Act of 1966, as amended, an undertaking
that, in the event of there being enacted in Bermuda any legislation imposing
any tax computed on profits or income, including any dividend or capital gains
withholding tax, or computed on any capital assets, gain or appreciation, or
any tax in the nature of an estate or inheritance tax or duty, the imposition
of such tax shall not be applicable to ADT Limited or any of its operations,
nor to the Common Shares, preference shares or other obligations of ADT
Limited, until the year 2016.  This undertaking does not, however, prevent the
application of Bermuda taxes to persons ordinarily resident in Bermuda.

Under current Bermuda law, ADT Limited is required to pay the Bermuda
Government an annual registration fee, which is calculated by a reference to
the authorized capital and share premium of ADT Limited.  ADT Limited pays the
maximum fee, which is currently $25,000 per annum.

of $744.7 million relating to the impairment of long-lived assets following
the adoption by the Company of Statement of Financial Accounting Standards No.
121 "Accounting for the Impairment of Long-Lived Assets and for Long-Lived

corporate restructuring in Europe.

(ii)    Loss on disposal of businesses in 1995 included a net loss of $65.8
million relating to the disposal by the Company of an interest in its United
Kingdom and Continental European vehicle auction services businesses offset by
a net gain of $31.4 million relating to the disposal by the Company of its
entire European electronic article surveillance business.  Gain on disposal of
businesses in 1992 related to the disposal by the ASH group of its entire
European loss prevention business.

(iii)   Other income less expenses in 1996 included a net gain of $53.4
million relating to the disposal of the Company's entire investment in
Limelight Group plc, and a net settlement gain of $65.0 million relating to an
agreement in full and final settlement of the Company's litigation against BDO
Binder Hamlyn ("BDO").  Other income less expenses in 1994 included net gains
of $21.5 million arising from the ownership of investments and a net write off
of $30.7 million relating to the Company's entire equity investment in Arius,
Inc. which was held by the ASH group.  Other income less expenses in 1992

discontinued operations for 1994 were net losses on disposal of the non-core
businesses amounting to $3.7 million.  Net sales from discontinued operations
amounted to $80.6 million in 1994, $96.9 million in 1993 and $101.4 million in
1992.  These net sales are not included in net sales in the consolidated
income statement data.

(v)     Extraordinary items principally were comprised of the gains and losses
arising on reacquisition/ repayment and the write off of net unamortized
deferred refinancing costs relating to the early extinguishment of certain
amounts outstanding under the Company's long-term debt obligations, and were
stated net of applicable income taxes.

(vi)    The calculation of primary earnings per common share was based on the
weighted average number of common shares in issue during the period.  Such
weighted average number of common shares in issue for the years ended December
31, 1996, 1995, 1994, 1993 and 1992 was 137,114,415, 138,283,458, 136,148,361,
122,043,139 and 113,480,672 common shares, respectively.

(viii)  During 1994 the Company redeemed a significant proportion of its
convertible redeemable preference shares.  The net effect of this transaction
was to reduce the carrying value of the convertible redeemable preference
shares by $422.0 million.  The Company funded the redemption from cash on hand
and through the drawdown of long-term debt facilities.

(ix)    During 1993 the Company issued common shares for cash resulting in net
proceeds of $154.8 million.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
        RESULTS OF OPERATIONS


INTRODUCTION

In September 1996 the Company merged with and acquired the whole of the issued
capital of ASH, a United Kingdom quoted company.  ASH is engaged in the
provision of electronic security services in North America and Europe.  The
merger with and acquisition of ASH by the Company has been accounted for by
means of the pooling of interests method of accounting pursuant to Accounting
Principles Board Opinion No. 16.  The pooling of interests method of
accounting assumes that the combining companies have been merged since their
inception, and the historical consolidated financial statements for periods
prior to consummation of the merger are restated as though the companies have
been combined since their inception.  Accordingly, the accompanying
consolidated financial statements give effect to the transaction by means of
the pooling of interests and have been restated.

During 1995 management commenced a strategic review of the Company's business
operations and its corporate organizational structure with a view to
developing a business strategy which would place the Company in a stronger
position to deal with the changing business environment and challenges facing
its core service businesses in the late 1990s.  As part of this strategic
review, management approved the redeployment of certain of the Company's assets
in order to further concentrate the Company's resources on the electronic
security services operations, principally in the United States, where
management believes the greatest potential for future growth lies.
Consequently, Actron Group, the Company's European electronic article
surveillance business, was disposed of in November 1995 and in December 1995
the Company disposed of an interest in its European vehicle auction services
businesses.

During the fourth quarter of 1995, the Company entered into an agreement for
the acquisition of Alert, the tenth largest electronic security services
company in the United States, with a predominantly residential customer base
located principally in Texas, Florida and Georgia.

As part of the strategic review of its business operations undertaken during
1995, and in the context of the acquisition of Alert and the disposal of an
interest in the European vehicle auction services businesses, management
commenced an evaluation of the entire group corporate structure, and the
administrative, accounting and management information systems of its United
States electronic security services division (the "Re-Engineering Project").
The Re-Engineering Project, which is on-going, is intended to modify and
improve the entire structure of the business operations in order to create a
more profitable, efficient organization with significantly improved marketing,
selling, installation and servicing capabilities supported by upgraded
management information systems.

During 1996 the restructuring in the electronic security services division
included a reorganization of senior management, the closure of a major
corporate office in Parsippany, New Jersey, and a realignment of the
organizational structure along the functional business lines of residential,
commercial and customer service, rather than along geographic lines.

During 1996, as a result of the acquisition of ASH and the further development
of the Re-Engineering Project under the control of new senior management, the
Company identified the need to extend the process of strategic change to
include a significantly expanded agenda.  As a result, various strategic
initiatives have been added to the corporate plan and the implementation of
these plans is currently in progress and will continue throughout 1997.  In
the United States the plans relate principally to a significant investment in
technological infrastructure enhancements to facilitate further consolidation
of the Company's entire customer monitoring center network down to four, state
of the art, customer service centers, and to place the Company in a stronger
position to take advantage of the significant opportunities in the changing
market place.  In Europe, the plans relate principally to the merger,
integration and consolidation of the Company's existing electronic security
services businesses with that of ASH.

                                    23


RECENT DEVELOPMENTS

In November 1996 the Company announced that it intended to dispose of the
vehicle auction services operations in the United States in order to
concentrate further on the expansion of the Company's electronic security
services business.  Accordingly, the Company's vehicle auction services
business segment was then initially reclassified as a discontinued operation
for all years presented.  The preliminary, summarized consolidated results of
operations of the Company for the year ended December 31, 1996 were announced
on March 3, 1997, and were filed under Schedule 14A.  On March 17, 1997 the
Company announced that the aforementioned intention had been rescinded and
that the vehicle auction services operations in the United States would no
longer be disposed of.  Accordingly, all consolidated financial information
set forth in this Form 10-K, including the audited consolidated financial
statements of the Company, is presented with the Company's vehicle auction
services business segment classified as a continuing operation for all years
presented.  There is no net effect on the reported net income and total
shareholders' equity when comparing the preliminary, summarized consolidated
results of operations of the Company referred to above and the consolidated
financial information set forth in this Form 10-K.  All differences
relate to the reclassification of the vehicle auction services business
segment from discontinued operations to continuing operations.

In December 1996 Western Resources, Inc. ("Western") announced its intention
to commence an offer to exchange all of ADT Limited's outstanding common
shares for consideration consisting of cash and shares of Western common
stock.  On March 3, 1997 the Company announced that its board of directors had
determined that the offer made by Western was inadequate and not in the best
interests of ADT Limited's shareholders.  On March 17, 1997 the offer made by
Western commenced.

On March 17, 1997 the Company announced that it had entered into a definitive
merger agreement, subject to shareholder approval and other customary matters,
with Tyco International Ltd. ("Tyco"), a United States quoted company engaged
in the manufacture of industrial and commercial products.  Tyco shareholders
will receive one common share in the combined company for each Tyco common
share and ADT Limited shareholders, through a reverse stock split, will
receive 0.48133 common shares in the combined company for each ADT Limited
common share.

The information presented below should be read in conjunction with, and is
qualified by reference to, the consolidated financial statements of the
Company and the related notes thereto and the consolidated financial statement
schedules.

Electronic Security Services

Net sales derived from the electronic security services division are dependent
on the volume of new customer installations and the number of customers under
contract for the provision of electronic monitoring services.  A majority of
the division's revenues are derived from contractually recurring fees for
electronic monitoring and maintenance of security systems installed at
customer premises and other related services.  The remainder of the division's
revenues are derived from  the outright sale and installation of security
systems, the installation of security systems in accordance with a monitoring
service agreement and the maintenance of security systems on a non-contractual
basis.  Security system installation revenues are recognized when the
installation of a system is complete.  Where a system has been installed in
accordance with the terms of a monitoring service agreement, the Company
retains ownership of the system and  all direct installation costs, which
include materials, labor and installation overheads, are capitalized and
recorded as a fixed asset under subscriber systems.  These subscriber systems
are depreciated over their estimated useful life, which is principally 14
years and 10 years for commercial and residential systems, respectively, or,
in the case of commercial systems, the actual contract duration if shorter.
All selling and marketing costs are expensed in the year incurred.

                                    25


The following table presents the approximate number of commercial and
residential customers in North America and Europe contracting with the Company
for the monitoring or maintenance of electronic security systems together with
the annualized service revenue under contract as of December 31, 1996, and the
annual combined discontinuance rate for commercial and residential contracts
in respect of 1996.
                                                            

Number of Commercial   Number of Residential   Annualized Service      Annual Combined

      672,000               1,149,000                $920m                 10.4%



ADT defines annualized service revenue as the annualized service billing
arising from its customer base at a point in time for monitoring, maintenance
and related services.  The aggregate annualized service billings amount takes
account of cancellations or terminations, increases in contract revenues due
to new contracts, additional services to existing customers and rate
variations at the date of computation.  The actual amount of service revenue
for future periods will vary in accordance with changes in the customer base
and fees charged.

ADT calculates the annual combined discontinuance rate by dividing the
annualized service revenue from contracts cancelled or reduced in price during
the year by the annualized service revenue in force at the beginning of the
year, expressed as a percentage.

Since 1987 the division's goals have been to create a lower cost, more
efficient operation, suitable for long-term growth and greater profitability,
and to take advantage of the economies of scale resulting from the utilization
of the existing infrastructure which services its commercial customer base.
During this period the Company equipped its regional customer monitoring
centers with enhanced computer technology to further automate the monitoring
process and increase monitoring capacity.  As a result of increased monitoring
and service capacity, and a lower cost structure due to manpower reductions
and reduced facility costs, in the early 1990s the Company began marketing
electronically monitored security systems and services at lower installation
price points to residential customers throughout North America.  As a result
of the rapid expansion of the Company's business during the recent past and a
broader business strategy adopted by the Company in a changing market place,
the Company has identified the need to improve and expand its technological
and physical capacity in order to expand its customer base and product range.
Consequently, the Company has approved a plan to significantly enhance its
monitoring capacity, service quality and ability to expand its service and
product range.  The Company will continue to aggressively market residential
security systems in North America, while also focusing on opportunities for
growth in the commercial sector as the economies in North America and Europe
improve.

Further details of the electronic security services division's business
strategy are set out under "Description of Business - Business Description -
Electronic Security Services."

                                    26


1996 compared with 1995

Net sales of the division increased 4.1 per cent in 1996 to $1,406.2 million
from $1,350.9 million in 1995.  This sales increase was attributable to an
increase of $102.1 million in the sales of the North American operations offset
by a $46.8 million decline in the sales of the European operations, which was
due to the exclusion of sales of the European electronic article surveillance
operation and certain businesses operating in the ASH group, all of which were
disposed of during 1995.  In North America the increase in sales was
principally due to the first time inclusion of the sales of Alert which was
acquired in December 1995, as well as increased recurring monitoring and
maintenance revenues arising from a larger base of residential security
systems.  Although unit residential security systems sales in North America
increased in 1996 compared to 1995, due to price competition in the market
place, residential installation revenues in North America showed a modest
decline in 1996 compared with 1995.  The commercial business in the United
States remained flat in both new system sales and installation revenues, and
growth in recurring commercial revenues continues to be affected by these
factors.  In Europe, after allowing for business disposals and the effect of
foreign exchange, sales showed a modest increase in 1996 compared with 1995.

Operating results of the division declined from $172.4 million income in 1995
to a $756.5 million loss in 1996, principally due to a charge for the
impairment of long-lived assets of $731.7 million and restructuring and other
non-recurring charges of $232.5 million in 1996.

Operating income of the division before the charge for the impairment of
long-lived assets and restructuring charges increased 7.2 per cent in 1996 to
$207.7 million from $193.8 million in 1995.  Operating income before the charge
for the impairment of long-lived assets and restructuring charges as a
percentage of net sales ("operating margin") increased to 14.8 per cent in
1996 from 14.3 per cent in 1995.  The increase in operating income before the
charge for the impairment of long-lived assets and restructuring charges
principally reflected the first time inclusion of Alert, the disposal of the
European electronic article surveillance operation in November 1995, and the
continuing success of the North American residential security systems sales
program, which has achieved further advances in recurring revenues in 1996.
However, this improvement has been offset by continued price competition and by
increased marketing and selling costs, which have caused the contribution from
residential installation revenues and outright residential sales to show a
modest decline.  The North American commercial installation revenues and
outright sales remained flat.  The contribution in Europe showed a modest
increase.

1995 compared with 1994

Net sales of the division increased 9.2 per cent in 1995 to $1,350.9 million
from $1,236.6 million in 1994 (excluding net sales of $16.7 million relating
to the Company's electronic security services businesses in Australia and New
Zealand, disposed of in June 1994).  This increase was attributable to
increases in net sales of $90.2 million and $24.1 million in North America and
Europe, respectively.  The sales increase in North America was principally due
to increased recurring monitoring and maintenance revenues arising from a
larger base of residential security systems.  In addition, the commercial
business in the United States experienced improved growth in new system sales
and installation revenues.  However, corporate downsizing and cost containment
has meant that growth in recurring revenues from the commercial sector has
been modest.  Sales in Canada, however, have marginally declined.  The
increase in sales in Europe was due to increased sales in the commercial
business, particularly in the United Kingdom, as well as increased recurring
monitoring and maintenance revenues from commercial customers, and the
strengthening of European currencies against the US dollar.

Operating income of the division declined from $182.1 million in 1994 to
$172.4 million in 1995, principally due to restructuring and other
non-recurring charges of $21.4 million in 1995.

                                    27


Operating income of the division before restructuring charges increased 6.5
per cent in 1995 to $193.8 million from $181.9 million in 1994 (excluding
operating income of $0.2 million relating to Australia and New Zealand,
disposed of in June 1994).  Operating margin declined from 14.7 per cent in
1994 (after excluding Australia and New Zealand) to 14.3 per cent in 1995
reflecting the higher cost of adding new residential customers in North America
during 1995.  The increase in operating income before restructuring charges in
North America reflected the continuing success in the United States of the
residential security systems sales program and growth in the sale of new
systems and installation revenues in the commercial sector.  The growth in
residential and commercial sales resulted in increased installation fees and
related monitoring and maintenance revenues and increased utilization of the
monitoring network in the United States.  In Canada, however, sales and
margins have fallen and the overall business performance was disappointing.
In Europe operating income before restructuring charges showed a modest
increase despite pressure on margins in the electronic article surveillance
business.  In November 1995 the Company disposed of its entire electronic
article surveillance business.

Restructuring and other non-recurring charges

During 1995, the Company commenced a strategic review of its business
operations with a view to developing a business strategy which would place the
Company in a stronger position to deal with the changing business environment
and challenges facing its core electronic security services businesses in the
late 1990s.  This strategic review process continued during 1996 following the
completion of the acquisition of Alert, the senior management reorganization
which took place in the first quarter of 1996, and the identification by the
new senior management team of the need to expand significantly the terms of
reference of the restructuring in the United States.  The effects of the
Re-Engineering Project and the consequent restructuring are more fully
described in note 5(i) of the notes to consolidated financial statements.  As
a consequence of the Re-Engineering Project, in each of the fourth quarters
of 1996 and 1995, senior executive management approved a restructuring plan
which resulted in a charge for restructuring and other non-recurring items of
$134.7 million and $21.4 million, respectively.

During the fourth quarter of 1996, the Company commenced a strategic and
detailed review of the electronic security services businesses acquired as
part of the acquisition of ASH in September 1996.  In December 1996 senior
executive management approved a restructuring plan which is intended to merge
and integrate fully the ASH group into the ADT group by the end of 1997.  As a
consequence of the restructuring plan a charge for restructuring and other
non-recurring items of $97.8 millon was recorded in the fourth quarter of
1996.  Details of the restructuring are more fully described in note 5(i) of
the notes to consolidated financial statements.

Charge for the impairment of long-lived assets

Effective January 1, 1996, the Company was required to adopt SFAS 121.
Following the adoption of SFAS 121, in the first quarter of 1996 the Company
recorded an aggregate non-cash charge for the impairment of long-lived assets
of $731.7 million in the electronic security services division with a
consequential tax credit of $10.8 million.  The impairment charge comprised
$397.1 million relating to the ADT group, principally all of which related to
the carrying value of goodwill and other intangibles, and $334.6 million
relating to the ASH group, of which $121.0 million related to the carrying
value of subscriber systems installed at customers' premises which are
included in property, plant and equipment, and $213.6 million related to the
carrying value of goodwill and other intangibles.  Further details are set out
in note 6(i) of the notes to consolidated financial statements.

                                    28


Vehicle Auction Services

Net sales of the vehicle auction services division are a function of the
number of vehicles handled, the number of vehicles sold at auction and the
number of vehicles handled for which ancillary services are provided.  The
Company charges an entry fee for the majority of vehicles entered at auction.
On the sale of a vehicle at auction, the Company charges a separate seller's
and buyer's fee for each vehicle sold.  This fee per vehicle sold is either
a fixed fee or a variable fee directly related to the sale price achieved.
The fee structure for each vehicle transaction is based upon the contractual
relationship with the customer.  Revenues from additional services, which
include reconditioning, body repair, inspection, transportation and insurance
are related to the number of vehicles handled and are an additional integral
source of the division's revenue.

In December 1995 the Company disposed of an interest in its United Kingdom and
Continental European vehicle auction services businesses.

1996 compared with 1995

Net sales of the division declined from $432.9 million in 1995 to $297.8
million in 1996 due to the exclusion of the sales of European Auctions which
was sold in December 1995.

Net sales of the United States vehicle auction services business increased
10.4 per cent in 1996 to $297.8 million from $269.8 million in 1995.  The
volume of vehicles sold increased by approximately 7 per cent which was
principally due to an increase in the volume of vehicles sold for fleet lease
customers of approximately 35 per cent, while the volume of vehicles sold for
vehicle manufacturers and new and used vehicle dealers declined by
approximately 5 per cent and approximately 2 per cent, respectively.

Operating income of the division declined from $70.2 million in 1995 to $25.2
million in 1996 due to a charge for the impairment of long-lived assets of
$13.0 million (see note 6(ii) of the notes to consolidated financial
statements) and the exclusion of the operating income of European Auctions.

Operating income before the charge for the impairment of long-lived assets of
the United States vehicle auction services business increased 11.4 per cent in
1996 to $38.2 million from $34.3 million in 1995.  Operating margin increased
to 12.8 per cent in 1996 from 12.7 per cent in 1995.  The increase in
operating income and operating margin were due principally to the increase in
the volume of vehicles sold and to an increase in the ratio of vehicles sold
to vehicles entered for sale ("conversion ratio") to 56.6 per cent in 1996
from 55.3 per cent in 1995, which was due to a higher proportion of vehicles
entered for sale by fleet lease customers.

In December 1995 the Company disposed of an interest in European Auctions for
an aggregate consideration of $334.9 million.  The net loss on disposal of
$65.8 million included $136.5 million relating to the write off of net
unamortized goodwill and other intangibles and a $23.2 million charge relating
to cumulative currency translation adjustments.

1995 compared with 1994

Net sales of the division increased 15.1 per cent in 1995 to $432.9 million
from $376.1 million in 1994.  This increase was attributable to increases in
net sales of $40.3 million and $16.5 million in Europe and the United States,
respectively.  The increase in Europe was primarily attributable to an
increase in the number of vehicles sold in 1995 of approximately 7 per cent,
the inclusion of the vehicle reconditioning and transportation business in the
United Kingdom which was acquired in December 1994 and the strengthening of
European currencies against the US dollar.  In Europe the volume of vehicles
sold for new and used vehicle dealers, fleet lease customers and vehicle
manufacturers increased by approximately 5 per cent, approximately 10 per cent
and approximately 8 per cent, respectively.  In the United States the volume
of vehicles sold increased by approximately 3 per cent.  This was principally
due to an increase in the volume of vehicles sold for fleet lease customers of
approximately 30 per cent, offset by a decline, in each case, in the volume of
vehicles sold for vehicle manufacturers and new and used vehicle dealers of
approximately 5 per cent.

Operating income of the division increased 12.0 per cent in 1995 to $70.2
million from $62.7 million in 1994.  Operating income in Europe increased by
$6.9 million due to the increase in revenue per vehicle sold at auctions, the
inclusion of the vehicle reconditioning and transportation business in the
United Kingdom, effective overhead containment and the strengthening of
European currencies against the US dollar.  Operating income in the United
States increased by $0.6 million and operating margin declined from 13.3 per
cent to 12.7 per cent.  This was principally due to a decline in the
conversion ratio from 58.3 per cent in 1994 to 55.3 per cent in 1995 which was
due to a lower proportion of vehicles entered for sale by manufacturers and to
lower dealer conversion ratios.

                                    29


Corporate expenses

Corporate expenses comprise administrative, legal and general corporate
expenses net of other income and include all central costs incurred not
directly connected with the operational management of the Company's two
businesses which are responsible for their own corporate overheads.

The effects of the Re-Engineering Project and the merger of the ASH group into
the ADT group resulted in a charge for restructuring and other non-recurring
items at the corporate level in the fourth quarter of 1996 of $4.8 million.
During 1995 management evaluated the Company's entire group corporate
structure, in particular in the United Kingdom.  As a result, in December
1995, senior executive management approved a restructuring plan which resulted
in a charge for restructuring and other non-recurring items at the corporate
level of $12.8 million.  The corporate restructuring charge in 1994 of $4.5
million was principally attributable to the Company's corporate administration
in the United Kingdom.  Details of the restructurings are more fully described
in note 5(ii) of the notes to consolidated financial statements.

Interest expense                              (101.0)     (116.3)      (99.3)

Interest income increased in 1996 compared with 1995 principally due to the
effects of the disposal of the European vehicle auction division and the
European electronic article surveillance business in the fourth quarter of
1995, and the inclusion of $8.9 million interest income in 1996 related to the
ITS Vendor Note.  Interest income increased in 1995 to compared with 1994
principally due to the increase in the level of cash deposits held by the
Company in 1995.

Interest expense declined in 1996 compared with 1995 principally due to the
effects of the refinancing which took place in the third quarter of 1995.  In
1996 interest expense included $20.3 million (1995 - $9.4 million) relating
to Liquid Yield Option Notes discount amortization, and $3.7 million (1995 -
$5.3 million) relating to refinancing costs amortization.  Interest expense
increased in 1995 compared with 1994 principally due to the effects of the
financing of the redemption of a significant proportion of the Company's
convertible redeemable preference shares in 1994.  In 1995 interest expense
included $9.4 million (1994 - nil) relating to Liquid Yield Option Notes
discount amortization, and $5.3 million (1994 - $5.7 million) relating to
refinancing costs amortization.  The Company holds no derivative financial
instruments.

See Liquidity and Capital Resources and notes 21 and 23 of the notes to

long-term debt, respectively.

In December 1995 the Company disposed of an interest in its United Kingdom and
Continental European vehicle auction services businesses for an aggregate
consideration of $334.9 million (see notes 18 and 34 of the notes to
consolidated financial statements for further details).  The net loss on
disposal of $65.8 million included $136.5 million relating to the write off of
net unamortized goodwill and a $23.2 million charge relating to cumulative
currency translation adjustments.

During 1996 gains arising from the ownership of investments included a net
gain of $53.4 million relating to the disposal in November 1996 of the
Company's entire investment in Limelight Group plc.  The write off in value of
associate in 1994 related to the Company's entire equity investment in Arius,
Inc. which was held by the ASH group.  In December 1996 the Company and BDO
entered into an agreement in full and final settlement of the Company's
litigation against BDO.  The net gain arising on this settlement, after the
write off of certain deferred legal costs, amounted to $69.7 million, of which
$65.0 million was included in other income less expenses and $4.7 million was
included in interest income.  See note 8 of the notes to consolidated
financial statements for further details of other income less expenses.

Income taxes

Current income taxes principally relate to state, local and other tax
liabilities incurred in the United States and other non-US tax liabilities.
The Company's effective income tax rate as adjusted for financial reporting
purposes has increased in 1996, 1995 and 1994.  This effective tax rate
increase principally arose from an increase in the deferred tax charge.
During 1996 the Company's deferred income tax charge was impacted by tax
effects of the restructuring in the United States and other non-US tax
jurisdictions.  See note 9 of the notes to consolidated financial statements
for further details of income taxes.


Discontinued operations

Discontinued operations comprised the disposal during 1994 of all the
Company's non-core businesses.  The Company no longer has any interests in
non-core businesses.  Included in the loss from discontinued operations for
1994 were net losses on disposal of the non-core businesses amounting to $3.7
million, which included $19.1 million relating to the write off of net
unamortized goodwill and other intangibles on the disposal of the non-core
businesses.  The net income from operations for 1994 included in the loss from
discontinued operations amounted to $0.4 million on net sales of $80.6 million.

                                    31


Extraordinary items

Extraordinary items in 1996 and 1995 included net losses amounting to $1.2
million and $1.5 million, respectively, arising on the reacquisition of
certain of the Company's senior subordinated notes.  Further details are
provided in notes 11 and 23(ii) of the notes to consolidated financial
statements.

In September 1996 the Company repaid in full all amounts owed by the ASH group
under its senior notes and bank credit agreement.  Further details on the net
loss amounting to $4.6 million which arose on these transactions are provided
in notes 11 and  23(vi) of the notes to consolidated financial statements.

In December 1996 the Company gave notice that it would redeem in full all
amounts outstanding to the convertible capital bond holders owed by the ASH
group.  Further details on the net loss amounting to $1.6 million which arose
on this transaction are provided in notes 11 and 23(v) of the notes to
consolidated financial statements.

In July 1995 and December 1996 the Company repaid in full and cancelled
certain bank credit agreements as part of refinancing arrangements at the
time.  Further details of the net losses amounting to $8.3 million in 1995 and
$1.0 million in 1996 which arose on these transactions are provided in notes
11,  23(iii) and 23(iv) of the notes to consolidated financial statements.

Dividends on preference shares

As a result of the redemption of a significant proportion of the Company's
convertible redeemable preference shares in 1994, dividends payable on the
balance of such shares outstanding were negligible in 1996 and 1995.

Effects of inflation

Due to the relatively low levels of inflation experienced in 1994, 1995 and
1996 in the major markets in which the Company operates, inflation did not
have a significant effect on the results of the Company in these years.

LIQUIDITY AND CAPITAL RESOURCES

Consolidated cash flow information

The net decrease in cash and cash equivalents amounted to $135.0 million,
after the positive effect of currency translation on cash and cash equivalents
of $1.4 million.  Net cash of $308.7 million provided by operating activities
was offset by net cash utilized by investing activities of $328.4 million and
net cash utilized by financing activities of $116.7 million.

Net cash provided by operating activities of $308.7 million principally
included cash provided by the Company's electronic security services and
vehicle auction services divisions less other expenses and adjusted for the net
increase in working capital.  Within the net increase of $32.7 million in
working capital were increases in accounts receivable of $11.9 million and
inventories and other assets of $15.0 million and a net decrease in
liabilities of $5.8 million, principally relating to increases in accounts
payable and deferred revenue and a decrease in other liabilities.  The
movement in accounts receivable was principally due to an increase in accounts
receivable in the vehicle auction services division.  The movement in deferred
revenue was principally due to the timing of billings within the electronic
security services division.

Net cash utilized by investing activities of $328.4 million was principally
due to capital expenditures of $314.2 million and $25.7 million in the
electronic security services and vehicle auction services divisions,
respectively, $25.5 million relating to the acquisition of the minority
interest in Alert and $34.6 million relating to the purchase of customer
contracts to provide electronic security monitoring.  These were principally
offset by $15.4 million received on the disposal of certain investments in and
loans to associates and $54.1 million received on the disposal of other
investments, principally Limelight Group plc.

                                    32


Net cash utilized by financing activities of $116.7 million was principally
due to the repayments of long-term debt of $209.9 million, principally
relating to the ASH group, and the purchase of $23.1 million of the Company's
senior subordinated notes at a cost of $24.0 million.  These were principally
offset by $86.8 million relating to the proceeds from long-term debt and $24.7
million realized on the issue of common shares.

Cash, liquid resources and sources of finance

Liquid assets available to the Company at December 31, 1996 represented cash
and cash equivalents of $215.9 million.  At December 31, 1996 the Company had
available but undrawn facilities of $35.9 million under its revolving bank
credit agreement.

In July 1996, as part of the then agreement to combine with Republic
Industries, Inc.  ("Republic"), ADT Limited granted to Republic a warrant
to acquire 15 million common shares of ADT Limited at an exercise price of
$20 per common share.  Following termination of the agreement to combine
with Republic, the warrant vested and was exercisable by Republic in the
six month period commencing September 27, 1996.  On March 21, 1997 the
warrant was exercised by Republic and the Company received $300 million in
cash.

Future commitments and cash requirements

Capital expenditures during 1997 are estimated to be approximately $487
million which represent normal replacement needs and the purchase of
additional equipment, facilities and customer contracts necessary to meet
planned increases in sales.  Approximately 90 per cent of the capital
expenditures projected for electronic security services relates to
installation of subscriber systems at customers' premises.  This amount
does not include any amounts for acquisitions which the Company may pursue
from time to time.

The Company believes that the working capital at December 31, 1996, its
available credit facilities and the current cash flows from operations are
adequate for the Company's normal growth and operating needs, the funding of
its capital expenditures budget and the current servicing of its debt
requirements.

ADT Limited has no present intention to pay any dividends on its common shares
but will keep its dividend policy under review in the light of prevailing
circumstances.  Under the terms of the senior notes and revolving bank credit
agreement ADT Limited may not declare, pay or make any dividend or
distribution with respect to its common shares, except in certain defined
circumstances.  See note 23 of the notes to consolidated financial statements
for further details.

(1)  While officers enjoy certain perquisites, such perquisites did not exceed
     the lesser of $50,000 or 10 per cent of each officer's salary and
     bonus.  Except as set forth below under "Employment Contracts,
     Termination of Employment and Change in Control Arrangements", a
     change in control of the Company does not of itself require the
     payment of any moneys to any of the Named Officers.  However, such an
     event does accelerate the vesting of certain pension rights and the
     exercisability of certain stock options.

                                    37


(2)  The salary, bonus and all other compensation shown in respect of 1994 and
     1995 represent Mr.  Ashcroft's entitlement to those amounts.  Mr.
     Ashcroft utilized $2,500,000 of the compensation due to him for 1995,
     being the whole of his bonus entitlement of $2,233,219 and $266,781 of
     his other compensation to subscribe for options, at the rate of $2.50
     per option, to subscribe for Common Shares.  Mr.  Ashcroft also
     utilized $2,500,000 of the compensation due to him for 1994, being the
     whole of his bonus entitlement of $1,945,313 and $554,687 of his other
     compensation entitlement to subscribe for these options.

(3)  The other compensation due to Mr. Ashcroft in respect of 1996 represents
     the US dollar equivalent of Pound Sterling 851,344 being an amount in
     lieu of providing Mr.  Ashcroft with retirement and death benefits
     under a defined pension plan.  The amounts in respect of 1995 and 1994,
     and which are referred to in note (2) above, were the equivalents of
     Pound Sterling 1,217,341 and Pound Sterling 511,126, respectively.

(4)  Represents salary since joining ADT Security Services, Inc. in March
     1996.  Mr. Gross' annualized salary for 1996 was $220,000.

(5)  Represents the amount contributed to Mr. Lakey's retirement income plan
    (1995 - $14,822, 1994 - $14,138).

(6)  The salary amount shown for 1996 represents Mr. Richardson's entitlement
     to salary in the year.  Prior to becoming entitled to receive certain
     salary, however, Mr.  Richardson elected to receive options at the rate
     of $2.50 per option, to subscribe for Common Shares at an exercise
     price of $8.625 per share, in lieu of receiving $69,444 in salary (1995
     - $83,333, 1994 - $97,222).

(7)  Represents $4,500 contributed to a defined contribution 401(k) pension
     benefit plan (1995 - $4,500, 1994 - $4,500) and $1,961 which is the
     aggregate incremental cost to the Company of providing Mr.  Richardson
     with enhanced group term life insurance benefits (1995 - $1,961, 1994 -
     $1,980).

(8)  The salary amount shown for 1996 represents Mr. Ruzika's entitlement to
     salary in the year.  Prior to becoming entitled to receive certain
     salary, however, Mr.  Ruzika elected to receive options at the rate of
     $2.50 per option, to subscribe for Common Shares at an exercise price
     of $8.625 per share, in lieu of receiving $80,136 in salary (1995 -
     $104,167, 1994 - $128,198).

(9)  Mr. Ruzika earned a bonus for 1996 of $1,100,000 (1995 - $250,000) under
     a bonus arrangement by which payments are related directly to the
     performance of the Common Share price.

(10) Represents $37,639 contributed to Mr. Ruzika's retirement income plan
     (1995 - $35,777, 1994 - $34,003) and $2,684 which is the estimated
     aggregate incremental cost to the Company of providing Mr.  Ruzika
     with supplemental term life insurance (1995 - $1,655, 1994 - $1,636).

Option Grants in Last Fiscal Year

Shown below are all grants of share options to the Named Officers during
the fiscal year ended December 31, 1996.  The following table shows, along
with certain information, hypothetical realizable values of share options
granted for the last fiscal year, at assumed rates of cumulative share
price appreciation over the ten-year life of such options.  These assumed
rates of appreciation are set by the rules of the SEC and are not intended
to forecast appreciation of the price of the Common Shares.  These
hypothetical values have not been discounted to reflect their present
values.

- -------------------
(1) The options granted to Mr. Ashcroft and Mr. Ruzika represent the net
    increase in the number of options which were received by Mr. Ashcroft
    and Mr. Ruzika in connection with an amendment to a previously granted
    option on 3,000,000 and 125,000 Common Shares, respectively.  At the
    same time as the number of options was increased, the exercise price
    was also increased from $8.625 to $15.00.  All the other terms and
    conditions of the options, including the expiry dates, remained
    unchanged.

    Of the options granted to Mr. Gross, Mr. Lakey and Mr. Richardson, 50 per
    cent are exercisable after three years from the date of grant, 25 per
    cent are exercisable after 4 years from the date of grant and 25 per
    cent are exercisable after five years from the date of grant.

(2) Gains are reported net of the option exercise price but before taxes
    associated with exercise.  The amounts shown represent certain assumed
    rates of appreciation only.  Actual gains, if any, on option exercises
    are dependent on the future price performance of the Common Shares as
    well as the option holders' continued employment through the vesting
    period.  The potential realizable values reflected in this table may
    not necessarily be achieved.

    1996.

    which they have paid a subscription price of $2.50 per option which has
    been taken into account for the purpose of valuing these options.

Certain Defined Benefit Plans

The Company does not maintain any defined benefit or actuarial retirement
plans ("pension plans").  However, Mr.  Lakey, Mr.  Richardson and Mr.
Ruzika participate in pension plans that are maintained by indirect, wholly
owned subsidiaries of the Company.  Certain information is set forth below
regarding the pension plans in which Mr.  Lakey, Mr.  Richardson and Mr.
Ruzika, as well as other employees of the Company's subsidiaries,
participate.

Mr. Richardson is a participant in the ADT Pension Plan maintained by ADT
Group PLC ("ADT Group").  Mr.  Richardson is the only Named Officer who
participates in the ADT Group's Pension Plan (the "ADT Group Plan").  The
ADT Group Plan provides Mr.  Richardson an annual benefit payable for life
beginning at age 60.  The annual benefit is equal to 66.7 per cent of base
salary for the three years of the most recent ten years prior to retirement
that produce the highest average.  Mr.  Richardson's annual benefit payable
at age 60 for life is Pound Sterling146,095.  Since Mr.  Richardson has
already attained age 60, the benefit payable to him upon his actual
retirement will be adjusted based upon his actual retirement date.
Benefits payable under the ADT Group Plan are not offset by Social Security
benefits.

ADT, Inc. maintains a supplemental executive retirement plan (the "ADT
SERP").  Mr.  Lakey and Mr.  Ruzika are the only Named Officers who
participate in the ADT SERP.  Benefits for Mr.  Ruzika under the ADT SERP
are also supplemented under a Supplemental Benefit Agreement between Mr.
Ruzika and ADT Management Services Limited (the "Supplemental Benefit
Agreement").
                                    40


The ADT SERP provides benefits to Mr.  Lakey for a total of 20 years,
beginning at age 60.  This annual benefit is equal to 60 per cent of Mr.
Lakey's base salary for the three consecutive years that produce the
highest average.  This benefit is reduced by the value of any benefits
derived from employer contributions under any other retirement plan
maintained by ADT, Inc. or its affiliates.  Mr.  Lakey's estimated annual
benefit payable at age 60 for a total of 20 years, net of the estimated
offset attributable to employer contributions under certain defined
contribution plans, is $30,764.  The estimated offset is based on the
assumption that Mr.  Lakey will have 27 years of service at age 60.
Benefits are not offset by Social Security benefits.

The ADT SERP and Supplemental Benefit Agreement together provide benefits
payable to Mr.  Ruzika for a total of 20 years beginning at age 55.  This
annual benefit is equal to 65 per cent of base salary and bonuses for the
three consecutive years that produce the highest average.  Effective for
benefits accrued after December 31, 1994, the benefit is calculated using
base salary including, for this purpose, the purchase price of any options
to purchase the Company's shares received in lieu of base salary.  This
benefit is reduced by the value of any benefits derived from employer
contributions under any other retirement plan maintained by ADT, Inc. or
its affiliates.

Mr.  Ruzika's estimated annual benefit payable at age 55 for a total of 20
years, net of the estimated offset attributable to employer contributions
under certain defined contribution plans, is $361,802.  The estimated
offset is based upon the assumption that Mr.  Ruzika will have 28 years of
service at age 55.  Benefits are not offset by Social Security benefits.

Compliance with Reporting Requirements

The Company believes that, during 1996, all filing requirements under
Section 16(a) of the Exchange Act applicable to its officers, directors and
beneficial owners of more than 10 per cent of equity securities were
complied with on a timely basis.

                                    41


Employment Contracts, Termination of Employment and Change in Control
Arrangements

The Company has entered into a written employment agreement with Mr.
Ashcroft, dated as of May 8, 1993.  An amendment to the agreement was
approved on November 4, 1996, which provides that Mr.  Ashcroft shall serve
as Chairman of the Board and Chief Executive Officer until March 31, 2000,
subject to renewal for additional two-year terms thereafter.  Mr.
Ashcroft's initial base salary was $1,000,000 per annum subject to annual
review and adjustment by the Board but may only be reduced by a maximum of
15 per cent during the term of the agreement without Mr.  Ashcroft's
consent.  During 1996, Mr.  Ashcroft's base salary was increased to
$1,157,625 per annum.  Mr.  Ashcroft is also eligible for annual bonus
payments based upon an earnings-per-share target for the Common Shares set
each year, subject to a maximum bonus of $4,000,000.  The maximum bonus is
payable upon attaining 117.5 per cent of the targeted earnings per share.
As a term of the contract, Mr.  Ashcroft was granted options to purchase
1,000,000 Common Shares under the ADT 1993 Long Term Incentive Plan, with
50 per cent of such options exercisable at market value on the date of
grant, as defined, 25 per cent exercisable at 110 per cent of market value,
and 25 per cent exercisable at 120 per cent of market value, vesting in
equal annual installments over a three-year period commencing one year from
the date of grant and exercisable over a ten-year period.  The Company will
make annual payments to Mr.  Ashcroft calculated to provide him with
retirement and death benefits no less favorable than if he were a member of
ADT Group Plan.  Such annual payments will not be less than $450,000.  The
Company may terminate the agreement upon Mr.  Ashcroft's death, when Mr.
Ashcroft attains the age of 60, if Mr.  Ashcroft is unable to perform his
duties for 180 days due to ill heath, accident or otherwise, if Mr.
Ashcroft fails to discharge his duties or engages in conduct that is
materially injurious to the Company, or if Mr.  Ashcroft willfully and
continually commits a material breach of the agreement.  Mr.  Ashcroft may
terminate the agreement upon, among other reasons, a breach by the Company
which breach (except for a material breach) is not cured within 30 days, if
he is removed from his position as Chairman of the Board or his position as
Chief Executive Officer, or if the scope of his duties and responsibilities
becomes inconsistent with his position as an officer of the Company.

Mr.  Ashcroft may also terminate the agreement without cause at any time
upon 90 days notice.  In the event the agreement is terminated pursuant to
its terms by the Company or without cause by Mr.  Ashcroft upon 90 days
notice, Mr.  Ashcroft will be entitled to the pro rata portion of his base
salary, bonus payment, pension payment and other benefits but will not be
entitled to any additional payments.  If the agreement is terminated due to
a disability, Mr.  Ashcroft will be entitled to an additional payment equal
to two times his highest base salary.  In the event the agreement is
terminated by the Company without cause or by Mr.  Ashcroft with cause, Mr.
Ashcroft will be entitled to a severance payment equal to two times his
highest base salary and average bonus payment, annual pension payments for
the year of termination and the following two years, and one year of any
other benefits previously provided.

Mr.  Ruzika entered into an employment agreement with ADT as of February
26, 1997.  The agreement provides that Mr.  Ruzika will serve as Chief
Financial Officer of ADT and as President of ADT Security Services, Inc.,
ADT Operations, Inc. and ADT, Inc., subsidiaries of ADT, from March 1, 1997
until February 28, 1999, subject to renewal for additional two-year terms
thereafter.  Mr.  Ruzika's initial annual base salary will be $694,500 and
will be subject to annual review for possible adjustments.  Mr.  Ruzika
will also be eligible for annual bonus payments at the discretion of the
Company as well as other compensation and benefit plans of the Company
including stock option plans.  The termination provisions of this agreement
provide that in the event that agreement is terminated by ADT without cause
or by Mr.  Ruzika with cause, Mr.  Ruzika will be entitled to receive a
severance payment equal to twice his base salary and certain fringe
benefits.

Mr.  Lakey entered into an employment agreement with ADT, Inc. as of
January 16, 1997.  The agreement provides that Mr.  Lakey will have
operational responsibility for ADT's electronic security operations in
Canada and Europe from January 16, 1997 until December 31, 1999, subject to
renewal for additional two-year terms thereafter.  Mr.  Lakey's initial
annual base salary will be $265,000.  Mr.  Lakey will also be eligible for
annual bonus payments at the discretion of the Company as well as certain
other enumerated benefits and relocation expenses.  The termination
provisions of this agreement include a term to the effect that, in the
event that agreement is terminated by ADT without cause or by Mr.  Lakey
with cause, Mr.  Lakey will be entitled to receive his base salary and
certain fringe benefits for two years.

                                    42


Under the ADT SERP (and, in the case of Mr.  Ruzika, the Supplemental
Benefit Agreement), Mr.  Ruzika and Mr.  Lakey become fully vested in the
accrued benefits thereunder upon a Change in Control (as defined below) of
the Company or ADT, Inc.  Mr.  Ruzika also becomes fully vested upon a
Change in Control (as defined below) of ADT Management Services Limited.
If Mr.  Ruzika or Mr.  Lakey's employment is terminated within one year
from the date of a Change in Control, the terminated executive will
receive, in lieu of all other amounts due to him under the ADT SERP (and,
in Mr.  Ruzika's case, the Supplemental Benefit Agreement), a lump-sum
distribution equal to the present value of his accrued benefit and an
additional amount calculated under a formula intended to put him in the
same after-tax position that he would have been in if he had received a
lump-sum distribution of his accrued benefit on his normal retirement date.
Under this formula Mr.  Ruzika would currently receive an additional amount
of approximately $653,295 and Mr.  Lakey would currently receive an
additional amount of approximately $54,253.

A "Change in Control" is deemed to have occurred under the ADT SERP if :
(1) any person (other than Laidlaw, Inc. or its affiliates, collectively
the "Laidlaw Group") acquires more than 40 per cent of the Company's voting
stock (the triggering percentage has been reduced from 40 per cent to 35
per cent because the Laidlaw Group's beneficial ownership of the Company's
voting stock is less than 20 per cent);  (2) the Laidlaw Group becomes the
beneficial owner of more than 45 per cent of the Company's outstanding
voting stock;  (3) there is a change of 50 per cent or more in the
composition of the Company's directors during any 3-year period (unless the
change in directors was approved by two thirds of the directors in office
at the beginning of such 3-year period or directors who had previously been
elected with the requisite two thirds approval);  (4) a person acquires the
legal right to direct the management and policies of the Company (other
than by virtue of membership on the board of directors or a committee of
the board);  (5) the Company ceases to own, directly or indirectly through
subsidiaries, at least 80 per cent of the voting stock of ADT, Inc. or (6)
the shareholders of either the Company or ADT, Inc. approve a merger,
consolidation or a sale or disposition of all, or substantially all, of the
assets of the Company or ADT, Inc. as the case may be, with the relevant
company not surviving.  In the case of Mr.  Ruzika, the provisions of (4),
(5), and (6) above include a change in the ownership of ADT Management
Services Limited (as well as the Company or ADT, Inc.).

Mr.  Richardson entered into an employment agreement with ADT Automotive
Holdings, Inc.  ("ADT Automotive Holdings"), the corporate parent of ADT
Automotive, Inc., as of November 30, 1993.  The agreement provides that Mr.
Richardson will serve as Chief Executive Officer of ADT Automotive Holdings
and its subsidiaries from December 1, 1993 until July 31, 1996, subject to
renewal for additional one-year terms thereafter.  The agreement was
renewed on a year-to-year basis as of July 31, 1996.  The agreement
provides that the term will be extended for an additional one year period
thereafter unless either ADT Automotive Holdings or Mr.  Richardson shall
have given the other notice of intention not to extend the term six months
prior to July 31, 1997.  On January 29, 1997, ADT Automotive Holdings and
Mr.  Richardson entered into an agreement which provides that Mr.
Richardson's time to give such notice is extended to and including April
30, 1997.  Mr.  Richardson's initial annual base salary will be $300,000
and will be subject to annual review for possible increases.  Mr.
Richardson will also be eligible for annual bonus payments at the
discretion of the Company.  The termination provisions of this agreement
include a term to the effect that, in the event that agreement is
terminated by ADT Automotive Holdings without cause or by Mr.  Richardson
with cause, Mr.  Richardson will be entitled to receive his base salary and
certain fringe benefits for two years or the remaining term of the
agreement, whichever is longer.

                                    43


Mr. Richardson has also entered into an incentive compensation agreement
for payment upon the successful sale of ADT Automotive Holdings by the
Company.  To the extent that the gross consideration for such sale exceeds
$430 million, on completion of the sale, ADT has agreed to pay Mr.
Richardson one-half of one per cent of such excess.  Gross consideration is
deemed to be the aggregate of proceeds received by ADT and debt remaining
in the auctions group which is assumed by the purchaser other than debt
considered to be a component of working capital, including bank overdrafts.

The Remuneration Committee of the Board has considered the recommendations
of the Company's outside independent human resources consultants, and has
reviewed industry practices concerning change in control severance
benefits.  In view of the need to minimize employee distractions and to
retain employee loyalty and dedication to the Company and to assure
attention to the Company's performance pending resolution of the Western
Offer, on February 27, on the recommendation of the Remuneration Committee,
the Board unanimously approved a severance agreement between Mr.  Gross and
ADT Security Services, Inc. in the event of a change of control, which
severance arrangement it has determined is fair and consistent with
industry practices.  The agreement provides that in the event that there is
a "Severance Change in Control" (as defined below) of ADT prior to February
9, 2000, and either (x)  Mr.  Gross's employment is terminated without
cause or (y)  Mr.  Gross terminates his employment for good reason, Mr.
Gross shall be entitled to (a) an amount of severance pay equal to twice
the total of (i) the higher of his annual full base salary as of the date
of termination or as of the date of the Severance Change in Control,
calculated on an annualized basis, plus (ii) the amount of the bonus
awarded to Mr.  Gross, if any, in the year prior to the date of termination
and (b) for the twelve-month period following such termination, benefits
substantially similar to the higher of those which Mr.  Gross is receiving
immediately prior to the date of termination or as of the date of the
Severance Change in Control.  A "Severance Change in Control" is deemed to
have occurred under the severance agreement if:  (1) any person becomes the
beneficial owner of more than 50 per cent of ADT's then-outstanding voting
securities;  (2) there is a change of 50 per cent or more in the
composition of the Company's directors during the term of the agreement
(unless the change in directors was approved by two thirds of the directors
in office at the beginning of such term or directors who had previously
been elected with the requisite two thirds approval);  (3) a person
acquires the legal right to direct the management and policies of the
Company (other than by virtue of membership on the board of directors or a
committee of the board); or (4) the shareholders of ADT approve a merger,
consolidation or a sale or disposition of all, or substantially all, of the
assets of ADT in which ADT is not the surviving entity.

In 1996, the Remuneration Committee of the Board resolved to increase the
subscription price and size of certain share options held by Mr.  Ashcroft
and Mr.  Ruzika.  In 1993, Mr.  Ashcroft and Mr.  Ruzika were granted
options to subscribe for 3,000,000 and 125,000 Common Shares respectively
at an exercise price of $8.625 per share for which each was required to pay
$2.50 per option, representing a total payment of $7,500,000 and $312,500
respectively, as a condition of vesting.  In 1996, the exercise price of
these options was increased to $15 and the number of related shares was
increased to 8,000,000 and 333,333 respectively.  All the other material
terms and conditions remained unchanged.  These changes were approved by
the shareholders of the Company.  At the time that the Remuneration
Committee approved these changes, the closing price of the Common Shares
was $14.75.  In November 1996, the Remuneration Committee resolved that the
options of Mr.  Ashcroft be transferable and, at the same time, in return,
Mr.  Ashcroft agreed to extend the termination date of his employment
agreement from March 31, 1998 to March 31, 2000.

                                    44


In November 1996, the Remuneration Committee also approved a bonus plan
under which Mr.  Ruzika is to receive a bonus of $200,000 when the Common
Share price exceeds $21.00 for a continuous period of 30 trading days and
$200,000 each time the Common Share price exceeds by $1.00 for a continuous
period of 30 trading days the share price level at which a bonus payment
was previously made.  The plan is due to expire in 2001 or such earlier
date as the Common Share price exceeds $30.00 for a continuous period of 30
trading days.  Should the share price exceed $30.00 within two and one half
years, Mr.  Ruzika will receive an additional payment of $1,000,000.

Report of Independent Accountants

To the Board of Directors and Shareholders of ADT Limited

We have audited the consolidated financial statements and the consolidated
financial statement schedules of ADT Limited listed in the index on page F-1.
These consolidated financial statements and consolidated financial statement
schedules are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these consolidated financial
statements and consolidated financial statement schedules based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards in the United States.  Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the consolidated
financial statements are free of material misstatement.  An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the consolidated financial statements.  An audit also includes assessing the
accounting principles used and significant estimates made by management, as
well as evaluating the overall consolidated financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of ADT Limited as at December 31, 1996 and 1995, and the consolidated results
of its operations and cash flows for each of the three years in the period
ended December 31, 1996 in conformity with generally accepted accounting
principles in the United States.  In addition, in our opinion, the
consolidated financial statement schedules referred to above, when considered
in relation to the basic consolidated financial statements taken as a whole,
present fairly, in all material respects, the information required to be
included therein.

As discussed in note 6 to the consolidated financial statements, effective
January 1, 1996, the Company adopted the provisions of Statement of Financial
Accounting Standards No. 121 "Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to Be Disposed Of".

     Consolidated Statements of Changes in Shareholders' Equity (continued)

(i)   Prior to the Company's merger with Automated Security (Holdings) PLC
("ASH") in September 1996 (note 3), ASH had issued and outstanding two classes
of convertible cumulative redeemable preference shares.  The dividends on
these preference shares have been charged to the accumulated deficit account
during the relevant periods.  Given the terms and conditions of the preference
shares and that the holders of these preference shares received ADT common
shares at the time of the Company's merger with ASH, the dividends have not
been included in the calculation of earnings per common share in any period
presented.

                                  ADT LIMITED

                  Notes to Consolidated Financial Statements

Note 1 - Basis of consolidated financial statements

The consolidated financial statements have been prepared in United States
dollars in accordance with generally accepted accounting principles in the
United States and as described in notes 2 and 3.  The preparation of
consolidated financial statements in accordance with generally accepted
accounting principles in the United States requires management to make
extensive use of estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the consolidated financial statements and the reported amounts of
revenues and expenses during the reporting period.  These management estimates
include an allowance for doubtful receivables, estimates of future cash flows
associated with assets, asset impairments, and useful lives for depreciation
and amortization, loss contingencies, income taxes and valuation allowances
for deferred tax assets, and the determination of discount and other rate
assumptions for pension and post-retirement employee benefit expenses.  Actual
results could differ from those estimates.  Certain figures at December 31,
1995 and for the years ended December 31, 1995 and 1994 have been reclassified
to conform to the 1996 presentation.

Note 2 - Summary of significant accounting policies

Principles of consolidation

The consolidated financial statements incorporate the financial statements of
ADT Limited ("ADT"), a company incorporated in Bermuda, and its subsidiaries
(the "Company").  ADT is a holding company with no independent business
operations or assets other than its investment in its subsidiaries,
intercompany balances and holdings of cash and cash equivalents.  ADT's
businesses are conducted through its subsidiaries.  The Company consolidates
companies in which it owns or controls more than fifty per cent of the voting
shares unless control is likely to be temporary.  The results of subsidiary
companies acquired or disposed of during the financial year are included in
the consolidated financial statements from the effective date of acquisition
or up to the date of disposal except in the case of pooling of interests (note
3).  All significant intercompany balances and transactions have been
eliminated in consolidation.

Associates

For investments in which the Company owns or controls more than twenty per
cent of the voting shares, or over which it exerts significant influence over
operating and financial policies, the equity method of accounting is used in
the consolidated financial statements.  The investment in associates is shown
in the consolidated balance sheets as the Company's proportion of the
underlying net assets of these companies plus any goodwill attributable to the
acquisitions less any write off required for a permanent diminution in value.
The consolidated statements of income include the Company's share of net
income of associates less applicable goodwill amortization.


Currency translation

The results of subsidiaries and associates located outside the United States
which account in a functional currency other than United States dollars are
translated into United States dollars at the average rate of exchange for the
year.  The assets and liabilities of subsidiaries and associates located
outside the United States which account in a functional currency other than
United States dollars are translated into United States dollars at the rate
ruling at the balance sheet date.  Currency translation adjustments arising
from the use of differing exchange rates from period to period are included as
a separate component in shareholders' equity.

The gains and losses arising from currency transactions are included in the
consolidated statements of income.

                                   F-10


Cash and cash equivalents

Cash and cash equivalents include cash on hand, demand deposits and highly
liquid instruments, with an original maturity of three months or less.  As a
result of the short-term maturity of these financial instruments their carrying
value is approximately equal to their fair market value.

Inventories

Inventories are carried at the lower of cost or net realizable value.  Cost
includes an addition for production overheads where appropriate and is
determined on a first-in first-out basis.

Property, plant and equipment

Property, plant and equipment are carried at cost less accumulated
depreciation.  Depreciation is provided to write off the cost of the assets
over their estimated useful lives, using the straight line method, at the
following annual rates:

Owned property and related improvements       2% to 4%
Leased property and related improvements      term of lease
Subscriber systems                            shorter of actual contract
                                              duration or 7%, and 10%
Other plant and equipment                     7% to 40%

Repairs and maintenance costs are expensed as incurred.  Gains and losses
arising on the disposal of property, plant and equipment are included in the
consolidated statements of income.

Goodwill and other intangibles

The goodwill that arises where the acquisition cost of subsidiaries and
associates exceeds the fair values attributable to the underlying net assets
is capitalized and is being amortized on a straight line basis over its
estimated useful life, covering periods not exceeding forty years.  Goodwill
arising on the acquisition of associates is included in investment in
associates.  Costs attributable to the acquisition, including the costs of any
reorganization arrangements, less related income, are treated as reducing the
value of the net assets acquired.  The carrying value of goodwill is evaluated
periodically in relation to the operating performance and future undiscounted
cash flows of the underlying businesses.  Where, in the opinion of the
Company, a permanent diminution in the value of goodwill has occurred, the
amount of the diminution is included in the consolidated statements of income.
Other intangibles principally comprise customer contracts which are being
amortized on a straight line basis over periods not exceeding ten years.

Income taxes

Deferred tax liabilities and assets are recognized for the expected future tax
consequences of events that have been included in the consolidated financial
statements or tax returns.  Deferred tax liabilities and assets are determined
based on the differences between the consolidated financial statements and tax
bases of assets and liabilities, using tax rates in effect for the years in
which the differences are expected to reverse.

                                    F-11


Share premium and contributed surplus

In accordance with the Bermuda Companies Act 1981, when ADT issues shares for
cash at a premium to their par value, the resulting premium is credited to a
share premium account, a non-distributable reserve.  When ADT issues shares in
exchange for shares of another company, the excess of the fair value of the
shares acquired over the par value of the shares issued by ADT is credited,
where applicable, to contributed surplus which is, subject to certain
conditions, a distributable reserve.

Net sales

Net sales represent the invoiced value of goods and services to outside
customers net of sales-related taxes.

Revenue recognition

Revenue from services or products is recognized in the consolidated statements
of income as services are rendered or deliveries made.  Service charges, which
consist of subscriber billings for services not yet rendered, are deferred and
taken into income as earned and the deferred element is all included in
long-term liabilities.  Revenue from the installation of electronic security
systems is recognized when installations are completed.

Pensions and post-retirement benefits

The Company operates various pension and post-retirement benefit plans
designed in accordance with conditions and practices in the countries
concerned.  Contributions or accruals for costs are based on periodic actuarial
valuations and are charged to the consolidated statements of income on a
systematic basis over the expected average remaining service lives of current
employees.

Note 3 - Merger with Automated Security (Holdings) PLC

In September 1996 ADT merged with and acquired the whole of the issued capital
of ASH, a United Kingdom quoted company.  ASH is engaged in the provision of
electronic security services in North America and Europe.  Under the terms of
the transaction, ASH shareholders received 3 ADT common shares for every 92
ASH ordinary shares, 2 ADT common shares for every 31 ASH 5 per cent
convertible cumulative redeemable preference shares and 2 ADT common shares
for every 31 ASH 6 per cent convertible cumulative redeemable preference
shares.  The total consideration in respect of the whole of the issued capital
of ASH consisted of the issue of 7,034,940 ADT common shares (note 30(i)).

The merger with and acquisition of ASH by ADT has been accounted for by means
of the pooling of interests method of accounting pursuant to Accounting
Principles Board Opinion No. 16.  The pooling of interests method of
accounting assumes that the combining companies have been merged since their
inception, and the historical consolidated financial statements for periods
prior to consummation of the merger are restated as though the companies have
been combined since their inception.  Accordingly, the consolidated financial
statements give effect to the transaction by means of the pooling of interests
and have been restated.

                                    F-12


The consolidated financial statements of ASH have previously been presented in
pounds sterling, ASH's functional currency.  For the purposes of these
consolidated financial statements, ASH's consolidated financial statements have
been translated into United States dollars at the appropriate exchange rates.
In addition, ASH's financial year end is November 30, with appropriate
quarterly period ends of February 28, May 31, and August 31.  These periods
have not yet been amended in order to facilitate timely reporting.  It is
these periods which have been used to give effect to the pooling of interests
with ADT.  Certain figures of ASH for all periods presented have been
reclassified to conform to the ADT presentation.

Combined and separate results of ADT and ASH for the periods preceding the
merger were as follows:

                               ADT Group   ASH Group Adjustments    Combined

During 1995 the Company commenced a strategic review of its business
operations and its corporate organizational structure with a view to
developing a business strategy which would place the Company in a stronger
position to deal with the changing business environment and challenges facing
its core service businesses in the late 1990s.  During 1996 this strategic
review process continued and was extended to include a significantly expanded
agenda.

(i)     As part of the strategic review the Company commenced an evaluation of
the administrative, accounting, management information systems and
technological infrastructures of its United States electronic security services
division (the "Re-Engineering Project").  The Re-Engineering Project, which is
on-going, is intended to modify and improve the entire structure of the
business operations.  As a consequence of the Re-Engineering Project, and
incorporating the effects of the acquisition of Alert Centre, Inc. ("Alert"),
in each of the fourth quarters of 1996 and 1995 senior executive management
approved a restructuring plan which resulted in a charge for restructuring and
other non-recurring items in the United States electronic security services
division of $131.6 million and $19.4 million, respectively.

The United States electronic security services division restructuring charge
in 1996 was principally attributable to planned technological infrastructure
enhancements to facilitate further consolidation of the Company's entire
customer monitoring center network together with all related operations, which
it is expected will be substantially completed by December 1997.  The
restructuring charge included the write off of certain property, plant and
equipment of $82.6 million, provision for idle property leases of $18.9
million, the termination of certain contractual obligations and other
settlement costs of $9.4 million, and other integration and restructuring
costs of $20.7 million.  The amounts paid and charged in 1996 against the
provisions for the termination of certain contractual obligations and other
settlement costs, and against other integration and restructuring costs,
amounted to $4.8 million and $4.3 million, respectively.

The United States electronic security services division restructuring charge
in 1995 was principally attributable to the closure of the Parsippany, New
Jersey and associated corporate offices, which will be substantially completed
by March 1997.  Full implementation of the restructuring plan will result in
the termination of approximately 250 employees of which approximately 180
employees had been terminated by December 31, 1996.  Employee severance and
other associated costs included in the restructuring charge amounted to $13.6
million, the write off of certain property, plant and equipment amounted to
$1.9 million, and other integration and restructuring costs amounted to $3.9
million.  The amounts paid and charged in 1996 against the provisions for
employee severance and other associated costs, and against other integration
and restructuring costs, amounted to $7.1 million and $3.5 million,
respectively.

                                    F-17


During the fourth quarter of 1996, the Company commenced a strategic and
detailed review of the electronic security services businesses acquired as
part of the acquisition of ASH in September 1996.  In December 1996 senior
executive management approved a restructuring plan which is intended to merge
and integrate fully the ASH group into the ADT group by December 1997, and
which resulted in a charge for restructuring and other non-recurring items in
the United Kingdom and the United States electronic security services
divisions of $68.6 million and $29.2 million, respectively.

The restructuring charge included the write off of certain property, plant and
equipment of $13.2 million, provision for idle property leases of $22.5
million, the termination of certain contractual obligations and other
settlement costs of $35.2 million, and other integration and restructuring
costs of $26.9 million.  The amounts paid and charged in 1996 against the
provisions for the termination of certain contractual obligations and other
settlement costs, and against other integration and restructuring costs,
amounted to $7.2 million and $1.0 million, respectively.

As part of the strategic review, in 1996 the Company also commenced an
evaluation of the customer monitoring center network in its Canadian
electronic security services division which resulted in a charge for
restructuring and other non-recurring items of $3.1 million.  The
restructuring charge included the write off of certain property, plant and
equipment of $1.3 million and provision for idle property leases of $1.8
million, of which $0.2 million was paid and charged in 1996.

As part of the strategic review, in 1995 the Company also commenced an
evaluation of the management information systems of its United Kingdom
electronic security services division which resulted in a charge for
restructuring and other non-recurring items in 1995 of $2.0 million
principally relating to the write off of certain property, plant and equipment.

(ii)    The effects of the Re-Engineering Project and the merger of the ASH
group into the ADT group resulted in a charge for restructuring and other
non-recurring items at the corporate level in 1996 of $4.8 million, comprising
other integration and restructuring costs, of which $3.0 million was paid and
charged in 1996.

During 1995 the Company also evaluated its group corporate structure, in
particular in the United Kingdom.  As a result, in the fourth quarter of 1995,
senior executive management approved a restructuring plan, which was
substantially completed by December 1996, which resulted in a charge for
restructuring and other non-recurring items at the corporate level of $12.8
million.

The corporate restructuring charge included the provision for idle property
leases of $5.6 million, the termination of certain contractual obligations and
other settlement costs of $4.8 million, and employee severance for four
executives, all of whom were terminated during 1996, and other associated
costs, of $2.4 million.  The amounts paid and charged in 1996 against the
provisions in the aforementioned categories were $0.6 million, $4.8 million and
$1.8 million, respectively.

The corporate restructuring charge in 1994 of $4.5 million was principally
attributable to the Company's corporate administration in the United Kingdom
and related to a provision for idle property leases.

                                              ======      ======      ======

Effective January 1, 1996, the Company was required to adopt 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 prescribes a methodology for assessing and measuring an impairment
loss that is significantly different from previous guidelines and procedures.

SFAS 121 requires the recoverability of the carrying value of long-lived
assets, primarily property, plant and equipment, and related goodwill, and
other intangible assets, to be reviewed for impairment whenever events or
changes in circumstances indicate that the carrying amount of an asset may not
be fully recoverable.  Under SFAS 121 it is necessary to evaluate for and
calculate an impairment loss at the lowest level of asset grouping for which
there are identifiable cash flows.  Under SFAS 121, if an asset being tested
for recoverability was acquired in a business combination accounted for using
the purchase method, the goodwill that arose in the transaction is included
in the impairment evaluation of that asset.

SFAS 121 requires that an impairment loss is recognized when the carrying
amount of an asset exceeds the sum of the estimated undiscounted future cash
flows of the asset.  Under SFAS 121 an impairment loss is calculated as the
difference between the carrying amount of the asset, including the related
goodwill, and its estimated fair value.  The carrying amount of the related
goodwill is eliminated before making any reduction in the carrying amount of
any other impaired long-lived asset.

Prior to the adoption of SFAS 121, the Company's policy was to evaluate for
impairment of long-lived assets, including goodwill, on an aggregate basis for
each business segment.  Management has determined that within the electronic
security services division the lowest level of asset grouping referred to
above can be determined on a country by country basis and, with effect from
the first quarter of 1996, further split principally in terms of commercial
and residential sectors.  The assets principally comprise subscriber systems
installed at customers' premises, which are included in property, plant and
equipment, and the related goodwill, and other intangible assets.  Within the
vehicle auction services division the lowest level of asset grouping can be
determined principally on an individual auction center basis, and the assets
principally comprise land and real estate, which are included in property,
plant and equipment, and the related goodwill.  Management has estimated the
fair values referred to above by using an analysis of estimated discounted
future cash flows as the best available estimate of fair value.  The basis of
the calculation was the Company's business strategy, plans and financial
projections, and an appropriate discount factor based on the Company's
estimated cost of capital.

                                    F-19


Following the adoption of SFAS 121, in particular the change in methodology
requiring the Company to evaluate assets at the lowest level of asset
grouping, rather than on an aggregate basis, in the first quarter of 1996 the
Company recorded an aggregate non-cash charge for the impairment of long-lived
assets of $744.7 million, as a separate line item in the consolidated
statements of income, with a consequential tax credit of $10.8 million.  The
$744.7 million impairment charge comprised $731.7 million relating to the
electronic security services division  and $13.0 million relating to the
vehicle auction services division.

(i)     The $731.7 million impairment charge in the electronic security
services division comprised $397.1 million related to the ADT group and $334.6
million related to the ASH group.

The $397.1 million impairment charge in the electronic security services
division of the ADT group related to an impairment in the carrying value of
subscriber systems principally in the commercial sector, including related
goodwill which principally arose on the acquisition of ADT Security Services
in 1987 of $395.3 million and other assets of $1.8 million.  Since 1989 the
Company's electronic security services operations in the residential sector
have developed at a very rapid rate based principally on internally generated
growth.  As a consequence, the Company's operations in the commercial sector,
which were acquired principally in 1987, have now been complemented by a
significant residential electronic security services operation.  This was a
major factor in the Company's decision to commence the Re-Engineering Project
in 1995, which is on-going.  In the context of the Re-Engineering Project and
changes in the electronic security services business environment, the
electronic security services operations have now been reorganized along
separate commercial and residential business lines, rather than on an
aggregate geographic basis, with effect from the first quarter of 1996, and
which is fully supported by management and financial reporting systems that
now record the results and cash flows of each sector separately.  When the
financial projections and estimated future cash flows of the commercial sector
were analyzed separately, they indicated that the carrying amount of the
related assets may not be fully recoverable.  This is reflective of increased
competition and other pricing factors as well as changes in the business
environment.  Accordingly, upon adoption of SFAS 121 the Company evaluated the
commercial sector assets for impairment with a resultant charge being
recorded.  In the United States the impairment charge amounted to $303.4
million.  In Canada, where the business performance has continued to be
disappointing, the impairment charge amounted to $56.7 million.  In Europe,
the impairment charge amounted to $37.0 million, principally due to the
business performance of certain countries not meeting previous expectations.

The $334.6 million impairment charge in the electronic security services
division of the ASH group related to an impairment in the carrying value of
subscriber systems of $121.0 million, and the carrying value of related
goodwill and other intangibles of $213.6 million which principally arose on
the acquisition of certain of the businesses of Modern Security Systems in
1989 and 1990, API Security in 1989 and the Sonitrol Group in 1992.  The
impairment charge amounted to $211.2 million and $123.4 million in the United
Kingdom and the United States, respectively.  In both the United Kingdom and
the United States, the adoption of SFAS 121 coincided with a reorganization of
both the commercial and residential business sectors to address, in part,
changes in the electronic security services business environment and
performance similar to those being addressed by the ADT group.  In addition,
the aggregate fair value of ADT common shares issued to ASH shareholders on
merger was significantly less than ASH's consolidated net asset value.  It was
for all these reasons that the Company reviewed the assets for impairment upon
adoption of SFAS 121.

(ii)    The $13.0 million impairment charge in the vehicle auction services
division related to an impairment in the carrying value of property and
related improvements, including related goodwill which principally arose on
the acquisition of ADT Automotive in 1987.

(i)     Realized gains and losses arising from the ownership of short-term and
long-term investments are principally stated before carrying costs of
interest, administrative and other expenses.  During 1996 gains arising from
the ownership of long-term investments comprised a net gain of $53.4 million
relating to the disposal in November 1996 of the Company's entire investment
in Limelight Group plc, a United Kingdom quoted company, which was previously
valued and accounted for by the Company at a nominal amount, a net gain of
$1.2 million relating to the disposal of the Company's equity investment in
Integrated Transport Systems Limited (notes 18 and 34) and other net losses of
$0.2 million principally arising from the disposal of other non-core
investments.

During 1995 losses arising from the ownership of long-term investments
comprised $5.1 million relating to the disposal, principally during the second
quarter of 1995, of the Company's entire equity investments in Compagnie
Generale de Protection et Securite SA ("CGPS") and Microtech Security (UK)
Limited ("Microtech") which were held by the ASH group (note 18), and other
net gains of $0.1 million principally arising from the disposal of other
non-core investments.  The net loss on disposal of $5.0 million included $7.3
million relating to the write off of net unamortized goodwill and other
intangibles and a $1.1 million charge relating to cumulative currency
translation adjustments.

During 1994 gains arising from the ownership of long-term investments
comprised $4.2 million relating to the disposal of the Company's entire equity
investment in Nu-Swift plc, a United Kingdom quoted company, and other net
gains of $14.3 million principally arising from the disposal of other non-core
investments.

(ii)    The write off in value of associate in 1994 related to the Company's
entire equity investment in Arius, Inc. ("Arius"), a United States unquoted
company, which was held by the ASH group.  A detailed assessment of the
investment in Arius was carried out during 1994 and as a result a net write
off of $30.7 million was recorded, of which $26.5 million related to the write
off of net unamortized goodwill and other intangibles and $2.9 million related
to other provisions.  During 1995 Arius went into voluntary liquidation.

(iii)   During 1991 a lengthy review and evaluation of the businesses and
assets acquired in 1990 in respect of Britannia Security Group PLC
("Britannia") was undertaken by the Company.  This review revealed that, at the
time of the acquisition of Britannia by ADT certain assets, particularly
subscriber systems installed at customer premises, had been included in the
consolidated financial statements of Britannia at values materially in excess
of their net realizable value.  During 1992 ADT commenced legal proceedings
against Britannia's auditors at the time of acquisition, BDO Binder Hamlyn
("BDO"), to seek recovery of the damages suffered.  In December 1995 the High
Court of Justice in England awarded damages of approximately $160 million
(including interest) against BDO, plus the reimbursement of certain legal
costs incurred in connection with the litigation.  BDO then appealed against
the judgment.  At December 31, 1995 ADT did not recognize the award of any
damages in its consolidated statements of income and had deferred certain
legal costs incurred in connection with the litigation amounting to $11.1
million in order to match these costs with the award when recognized.  These
deferred costs were included in other long-term assets (note 20).

In December 1996 ADT and BDO entered into a settlement agreement, subject to
completion of certain additional documentation which was signed in February
1997, which included the payment to ADT of $77.5 million in cash (included in
other current assets (note 15)) together with a further deferred payment of
$8.6 million, in full and final settlement of the aforementioned proceedings,
including the judgment, accrued interest and costs.  As a result of the
settlement BDO have withdrawn their appeal.  The net gain arising on this
settlement amounted to $69.7 million, of which $65.0 million was included in
other income less expenses and $4.7 million was included in interest income.

                                    F-24


In September 1996 the Company repaid in full all amounts owed by the ASH group
under its senior notes and bank credit agreement (note 23(vi)), which were
subsequently cancelled, and which was financed from cash on hand and loans
drawn under the revolving bank credit agreement.  Extraordinary items included

Note 12 - (Loss) earnings per common share

The calculation of primary (loss) earnings per common share was based on the
weighted average of 137,114,415 (1995 - 138,283,458; 1994 - 136,148,361)
common shares in issue during the year which in 1996 did not allow for the
allotment of common shares under executive share option schemes, which are
considered common stock equivalents, because their effect was anti-dilutive as
a consequence of the net loss for the year.  Common stock equivalents included
in the weighted average number of common shares in issue during 1995 and 1994
were 2,921,286 and 2,503,059, respectively.  Primary (loss) earnings per
common share from continuing operations was based on adjusted net loss from
continuing operations available to common shareholders of $687.0 million (1995
- - $30.7 million net income; 1994 - $69.3 million net income).

(i)     In February 1996 the Company acquired the remaining 24.0 per cent of
the outstanding voting share capital of Alert, an electronic security services
company in the United States, not already owned by the Company, for an
aggregate cash consideration of $25.5 million, which was financed from cash on
hand.  The amount of goodwill arising from this acquisition was $10.3 million.
During 1996 the Company purchased other intangibles, principally customer
contracts, in North America and Europe for an aggregate cash consideration of
$34.6 million which was financed from cash on hand.

                                    F-27


In December 1995 the Company acquired 76.0 per cent of the outstanding voting
share capital of Alert, for an aggregate cash consideration of $69.0 million,
which was financed from cash on hand.  The amount of goodwill and other
intangibles arising from this acquisition was $80.1 million and $40.0 million,
respectively.  In January 1995 the Company acquired a vehicle auction services
business in Belgium for an aggregate cash consideration of $4.2 million, which
was disposed of in December 1995 as part of the disposal by the Company of an
interest in European Auctions (note 17(ii)).  During 1995 the Company also
acquired several small electronic security services businesses in the United
States and Europe for an aggregate cash consideration of $1.0 million.

These acquisitions have been accounted for using the purchase method.
Accordingly, the respective purchase prices have been allocated to assets
acquired and liabilities assumed based on their preliminary estimated fair
values.  These allocations resulted in goodwill and other intangibles of $44.9
million arising during the year (1995 - $123.0 million).

(ii)    In December 1995 the Company disposed of an interest in European
auctions (notes 18 and 34).  Net unamortized goodwill and other intangibles
on disposal of $136.5 million was included in the loss on disposal of
businesses (note 7(i)).  During 1995 the Company disposed of certain of the
European electronic security services operations and businesses operated by
the ASH group.  The net unamortized goodwill and other intangibles on
disposal of $2.8 million was included in the gain on disposal of businesses
(note 7(iii)).

(iii)   The accumulated cost, accumulated amortization and net book values of
the goodwill balance included within goodwill and other intangibles at
December 31, 1996 amounted to $421.0 million, $43.0 million and $378.0
million, respectively (1995 - $1,120.1 million, $206.9 million and $913.2
million, respectively).

In December 1995 the Company disposed of an interest in European Auctions to
Integrated Transport Systems Limited ("ITS") (note 34) for an aggregate
consideration of $334.9 million.

                                    F-28


The aggregate consideration received by the Company on closing was comprised
of cash of $235.1 million, $187.6 million aggregate principal amount at
maturity of a subordinated deep discount zero coupon loan note issued by ITS
maturing in March 2004 ("Vendor Note"), $31.1 million aggregate principal
amount at maturity of subordinated deep discount zero coupon loan notes issued
by ITS maturing in March 2004 ("Shareholder Loan Notes"), and a 43.1 per cent
interest in the ordinary share capital of ITS at an issue price of $2.0
million.

The Vendor Note is a sterling loan note with an issue price of $83.9 million,
reflecting a yield to maturity of 10.0 per cent per annum, and was valued by
the Company at $74.6 million.  There are no periodic payments of interest.
The Vendor Note is a subordinated, non-collateralized obligation of ITS and is
transferrable, under certain conditions, after December 1998.  The discount on
the Vendor Note of $9.3 million will be amortized on a basis linked to the
yield to maturity over the life of the loan note as a credit to interest
income, and represents the difference between the stated yield to maturity and
the prevailing market yield to maturity of approximately 11.5 per cent per
annum, for similar types of loan notes at the time the Vendor Note was issued
in December 1995.  The interest yield and discount amortization for 1996
amounted to $8.6 million and $0.3 million, respectively.

The Shareholder Loan Notes are transferrable sterling loan notes with an issue
price of $13.9 million, reflecting a yield to maturity of 10.0 per cent per
annum, and were valued by the Company at $13.3 million.  There are no periodic
payments of interest.  The Shareholder Loan Notes are subordinated,
non-collateralized obligations of ITS and are also subordinated to the Vendor
Note.

The aggregate fair market value of the Vendor Note and Shareholder Loan Notes
at December 31, 1995 amounted to $87.9 million, and was based on discounting
the loan notes at estimated current sterling interest rates on similar term
financial instruments.

The 43.1 per cent interest in the ordinary share capital of ITS was valued and
accounted for by the Company at $0.9 million.

In February 1996 the Company disposed of its entire interest in Shareholder
Loan Notes with an issue price of $13.9 million and valued by the Company at
$13.3 million (net of unamortized discount of $0.6 million), and 33.1 per cent
of the ordinary share capital of ITS valued by the Company at $0.9 million,
for an aggregate cash consideration of $15.4 million.  The net gain arising on
the transaction amounted to $1.2 million which was included in other income
less expenses (note 8(i)).

As a result of the above transaction, the Company now holds a 10.0 per cent
interest in the ordinary share capital of ITS, valued and accounted for by the
Company at a nominal amount, together with the Vendor Note, which at December
31, 1996 is disclosed as a long-term investment (note 19) and has been
accounted for at its amortized cost.

During 1995 the Company disposed of its entire equity investments in CGPS, a
French unquoted company, and Microtech, a United Kingdom unquoted company, for
an aggregate consideration of $8.6 million comprising cash of $7.8 million and
notes receivable of $0.8 million.  The net loss on disposal of $5.1 million,

and other intangibles and a $1.1 million charge relating to cumulative
currency translation adjustments, was included in other income less expenses

In connection with the refinancing of certain long-term debt obligations of
the Company certain fees and expenses were incurred.  These refinancing costs
are being amortized as interest expense through the consolidated statements
of income on a straight line basis over the terms of the respective lives of
the Company's various long-term debt obligations.  The refinancing costs
amortization for the year amounted to $3.7 million (1995 - $5.3 million; 1994
- - $5.7 million).  During the year $4.0 million (1995 - $13.6 million; 1994 -
nil) of net unamortized deferred refinancing costs, relating to the early
extinguishment of certain amounts outstanding under the Company's long-term
debt obligations, were written off as extraordinary items in the consolidated

(i)     The $250.0 million 8.25 per cent senior notes due August 2000 were
issued in August 1993, through a public offering, by ADT Operations, Inc., a
company incorporated in the United States and an indirect wholly owned
subsidiary of ADT, and are guaranteed on a senior basis by ADT and certain
subsidiaries of ADT Operations, Inc.  The senior notes are not redeemable
prior to maturity and interest is payable semi-annually.  The indentures
governing the senior notes contain certain covenants including limitations on
indebtedness, limitations on certain payments, including dividends on the
Company's common shares, and compliance with various financial and operating
covenants and prohibitions, and certain change in control provisions.  The
senior notes are non-collateralized senior obligations of ADT Operations, Inc.
ranking pari passu in right of payment with all other existing and future
senior indebtedness of ADT Operations, Inc. including indebtedness under the
revolving bank credit agreement referred to in (iv) below.

                                    F-32


(ii)    The $350.0 million 9.25 per cent senior subordinated notes due August
2003 were issued in August 1993, through a public offering, by ADT Operations,
Inc., and are guaranteed on a senior subordinated basis by ADT.  The senior
subordinated notes are redeemable in whole or in part, at the option of ADT
Operations, Inc., at any time after August 1998 at the following redemption
prices:  during the twelve month period beginning (a) August 1998 at 103.75
per cent (b) August 1999 at 102.50 per cent (c) August 2000 at 101.25 per
cent, and thereafter at 100.00 per cent of the principal amount.  Interest is
payable semi-annually.  The indentures governing the senior subordinated notes
contain certain covenants as set out for the senior notes in (i) above.  The
senior subordinated notes are non-collateralized, senior subordinated
obligations of ADT Operations, Inc. ranking pari passu with, or senior in
right of payment to, all other existing and future indebtedness of ADT
Operations, Inc. that is expressly subordinated to senior indebtedness of ADT
Operations, Inc.  During 1996 the Company reacquired in the market $23.1
million (1995 - $32.8 million) face value of the senior subordinated notes at
a purchase cost of $24.0 million (1995 - $33.7 million) which was financed
from cash on hand.  The loss arising on reacquisition of $0.9 million (1995 -
$0.9 million), and related costs of $0.5 million (1995 - $0.8 million), was
included in extraordinary items (note 11).

(iii)   In July 1995 ADT Operations, Inc. issued $776,250,000 aggregate
principal amount at maturity of its zero coupon subordinated Liquid Yield
Option Notes ("Notes") maturing July 2010.  The net proceeds of the issue
amounted to $287.4 million which was used to repay in full all amounts
outstanding under ADT Operations, Inc.'s previous bank credit agreement, which
was subsequently cancelled.  The issue price per Note was $383.09, being
38.309 per cent of the principal amount of $1,000 per Note at maturity,
reflecting a yield to maturity of 6.5 per cent per annum (computed on a
semi-annual bond equivalent basis).  There are no periodic payments of
interest.  The discount amortization on the Notes is being charged as interest
expense through the consolidated statements of income on a basis linked to the
yield to maturity.  The Notes discount amortization for 1996 amounted to $20.3
million (1995 - $9.4 million).  Each Note is exchangeable for common shares of
ADT at the option of the holder at any time prior to maturity, unless
previously redeemed or otherwise purchased by ADT Operations, Inc., at an
exchange rate of 28.23 common shares per Note.  During 1996 619 Notes with a
carrying value of $0.3 million were exchanged, at the option of the holders,
for 17,472 ADT common shares (note 30).  Any Note will be purchased by ADT
Operations, Inc. at the option of the holder as of July 2002 for a purchase
price per Note of $599.46.  At this time, if the holder exercises the option,
ADT has the right to deliver all or a portion of the purchase price in the
form of common shares of ADT.  Beginning July 2002 the Notes are redeemable
for cash at any time at the option of ADT Operations, Inc., in whole or in
part, at redemption prices equal to the issue price plus accrued original
issue discount to the date of redemption.  The Notes are guaranteed on a
subordinated basis by ADT.   If, on or prior to maturity, there is a change in
control, the holder has the right to require ADT Operations, Inc. to purchase
the Notes at the change in control purchase price.

(iv)    In August 1995 ADT Operations, Inc. entered into a new $300 million
revolving bank credit agreement which replaced in full its previous bank
credit agreement.  The new agreement has a term of five years and is
guaranteed on a senior basis by ADT and certain subsidiaries of ADT
Operations, Inc.  Amounts available under this facility are available for
borrowing and reborrowing (or issuance and reissuance in the case of letters
of credit up to a maximum of $100 million), subject to certain conditions at
that time, until June 2000 at which time all amounts are repayable in full.
At December 31, 1996 $83.0 million (1995 - $15.0 million) was drawn down under
the agreement, which has been classified in the current portion of long-term
debt, plus letters of credit amounting to $81.1 million (1995 - $81.0 million)
which have been issued and have terms of less than one year.  The Company
utilizes letters of credit to back certain financing arrangements and
insurance policies as well as for trade purposes.  The letters of credit
approximately reflect fair value as a condition of their underlying purpose.
The Company expects the counterparties to fully perform under the terms of the
agreements.

Amounts drawn down under the revolving bank credit agreement bear interest at
a floating rate equal, at the option of ADT Operations, Inc., to either the
alternative base rate plus a margin or the reserve adjusted LIBO rate plus a
margin.  The average rate of interest at December 31, 1996 was 6.5 per cent
(1995 - 7.6 per cent).

The revolving bank credit agreement contains certain financial and operating
covenants, including restrictions on the Company's ability to incur additional
indebtedness, limitations on certain payments, including dividends on the
common shares of ADT and ADT Operations, Inc., and certain other financial
covenants, including a minimum cash flow coverage ratio, a minimum debt to
total capitalization ratio and a minimum level of shareholders' equity, and
certain change in control provisions.

In December 1996 ADT Operations, Inc. entered into a new $200 million
revolving bank credit agreement, subject to completion of certain additional
documentation which was signed in January 1997, which replaced in full its
previous bank credit agreement, and which was subsequently cancelled.  The new
agreement has a term of one year and is guaranteed on a senior basis by ADT
and certain subsidiaries of ADT Operations, Inc.  Amounts available under this
new facility are available for borrowing and reborrowing (or issuance and
reissuance in the case of letters of credit up to a maximum of $100 million),
subject to certain conditions at that time, until January 1998 at which time
all amounts are repayable in full.  The interest rates and financial and
operating covenants in place under the new facility are substantially the same
as those referred to above for the previous bank credit agreement.

(v)     The 9.5 per cent sterling denominated convertible capital bonds due
July 2006 were issued by ASH Capital Finance (Jersey) Limited, a company
incorporated in Jersey and an indirect wholly owned subsidiary of ADT, and are
unconditionally and irrevocably guaranteed on a non-collateralized and
subordinated basis by ADT.  Interest is payable semi-annually.  The capital
bonds are convertible, at the option of the holder, into fully paid 2.0 per
cent (fixed cumulative dividend) exchangeable redeemable preference shares in
ASH Capital Finance (Jersey) Limited with a nominal value of one pence each.
The preference shares are unconditionally and irrevocably guaranteed on a
non-collateralized and subordinated basis by ADT.  The preference shares are
redeemable at their paid up value of  Pound Sterling 1 each and they are also
exchangeable, at the option of the holder, for fully paid common shares of ADT
at a price of  Pound Sterling 76.66 per common share, the price of which is
subject to adjustment under certain circumstances.  The capital bonds are
unconditionally and irrevocably guaranteed on a non-collateralized and
subordinated basis by ASH, and were formerly convertible into ordinary shares
of ASH.  Under the terms of the issue, ADT can require conversion of any
outstanding capital bond if 85 per cent of the issue has been previously
converted or purchased and cancelled, in which case the bond holders may elect
for redemption in lieu of conversion.  On or after June 1, 1996, ADT may
exercise a call option at 100 per cent of the aggregate paid up amounts of the
capital bonds outstanding.

In December 1996 ASH Capital Finance (Jersey) Limited gave notice to all bond
holders that in January 1997 it would redeem all of the capital bonds then
outstanding at a price equating to the denomination of each capital bond
together with all accrued interest due.  Accordingly, in January 1997 the
capital bonds were fully redeemed at their carrying amount, which was financed
from cash on hand and amounts drawn down under the sterling denominated bank
credit facility, as set out in (vii) below, and at December 31, 1996 have been
classified in the current portion of long-term debt.

(vi)    In September 1996 the Company repaid in full all amounts owed by the
ASH group under its senior notes and bank credit agreement, which were
subsequently cancelled, and which was financed from cash on hand and loans
drawn under the revolving bank credit agreement.  The loss arising on
repayment of $4.2 million, and related costs of $0.4 million, was included in
extraordinary items (note 11).

                                    F-34


During 1994 ASH issued $60.7 million of its 8.28 per cent senior notes due
January 1998 of which $5.6 million was in respect of yield maintenance.  The
senior notes were collateralized obligations of the ASH group.  The yield
maintenance amortization on the senior notes has been charged as interest
expense through the consolidated statements of income.  The yield maintenance
amortization for 1996 amounted to $1.5 million (1995 - $1.1 million; 1994 -
$0.6 million).  The effective rate of interest including yield maintenance was
10.7 per cent.

During 1995 ASH entered into a bank credit agreement totalling approximately
$134 million with a maturity date in January 1998.  The amounts drawn under
the agreement were collateralized obligations of the ASH group and bore
interest principally at LIBO rate plus a margin.

(vii)   Other long-term debt principally represents revolving facilities with
various banks falling due for repayment in 1999 bearing interest at a floating
rate equal, at the option of the Company, to either the alternative base rate
plus a margin or the reserve adjusted LIBO rate plus a margin.   The average
rate of interest at December 31, 1996 was 7.5 per cent (1995 - 6.9 per cent).
In addition, at December 31, 1996 $0.6 million (1995 - $2.0 million) in
letters of credit have been issued under certain of these facilities and have
terms of less than one year.

In January 1997 the Company entered into a sterling denominated bank credit
facility which is repayable on demand.  The amount drawn down under the
facility amounted to $26 million which was used to repay, in part, the amounts
owed under the convertible capital bonds in (v) above.  The facility is
guaranteed by ADT and certain of its subsidiaries.  Interest is payable at
LIBO rate plus a margin.

In March 1997 the Company entered into a new $154 million sterling denominated
bank credit facility of which $146 million is a term loan facility and $8
million is a revolving credit facility.  The term loan facility was fully
drawn down and, in part, was used to repay in full the $26 million drawn down
under the sterling denominated bank credit facility referred to above.  The
new facility has a term of five years and is guaranteed by ADT and certain of
its subsidiaries.  Interest is payable at LIBO rate plus a margin.

The average rate of interest on all long-term debt during the year was 8.0 per
cent (1995 - 8.2 per cent; 1994 - 8.4 per cent).

Based on estimated interest rates currently available to the Company for
long-term debt with similar terms and average maturities, the fair value of
all long-term debt at December 31, 1996 amounted to approximately $1,119
million (1995 - approximately $1,241 million).

Note 27 - Minority interests

At December 31, 1995 minority interests represent the 24.0 per cent interest
in the outstanding voting share capital of Alert held by the minority
shareholders of Alert and not owned by the Company.  The value is based on the
consolidated net assets of Alert on a historical cost basis.

In February 1996, following approval by Alert's shareholders, Alert was merged
into the Company and, as a result, those shares then held by the minority
shareholders and not owned by the Company were converted into the right to
receive in cash the price paid per share by the Company in the initial tender
offer.  Accordingly, the minority interest outstanding at December 31, 1995
has been eliminated.

(i)     5 3/4% convertible cumulative redeemable preference shares 2002 (par
value $1 each)

In April 1987 175,000 of these mandatorily redeemable preference shares were
issued for cash at a price of $1,000 each, and during the period to December
31, 1996 139,262 of these preference shares were converted into ADT common
shares.  The holders of these preference shares were entitled to a fixed
cumulative preferential dividend at the rate of 5 3/4 per cent per annum.
These preference shares were subject to redemption, at the option of the
holders, in January 1994 at 119.625 per cent of their issue amount.  ADT had
the right to require redemption or conversion of the preference shares in
certain circumstances.  This right was exercised in November 1996 and all
remaining preference shares were redeemed at their carrying amount.

(ii)    6% convertible cumulative redeemable preference shares 2002 (par value
        $1 each)

In September 1987 400,000 of these mandatorily redeemable preference shares
were issued for cash at a price of $1,000 each, and during the period to
December 31, 1996 225 of these preference shares were converted into ADT
common shares.  The holders of these preference shares were entitled to a
fixed cumulative preferential dividend at the rate of 6 per cent per annum.
These preference shares were subject to redemption, at the option of the
holders, in October 1994 at 138.375 per cent of their issue amount.  ADT had
the right to require redemption or conversion of the preference shares in
certain circumstances.  This right was exercised in November 1996 and all
remaining preference shares were redeemed at their carrying amount.

(iii)   Convertible cumulative redeemable preference shares (par value $1 each)

In November 1996 the board of directors of ADT determined that 2.5 million of
the 125 million authorized convertible cumulative redeemable preference shares
of $1 each be classified as Series A First Preference Shares Purchase Rights,
pursuant to the Shareholders Rights Plan referred to below, which have been
reserved for issuance upon exercise of the said Rights.

The rights attaching to the balance of 122.5 million convertible cumulative
redeemable preference shares of $1 each, none of which are issued and
outstanding, as to dividends, return of capital, redemption, conversion,
voting and otherwise may be determined by ADT on or before the time of
allotment.

In November 1996 the board of directors of ADT adopted a Shareholder Rights
Plan ("the Plan").  Under the Plan each ADT common shareholder received a
distribution of one right for each ADT common share held.  Each right entitles
the holder to purchase from ADT shares of a new series of first preference
shares at an initial purchase price of $90 per one hundredth of a first
preference share.  The rights will become exercisable and will detach from the
common shares a specified period of time after any person becomes the
beneficial owner of 15 per cent or more of ADT's common shares, or commences a
tender or exchange offer which, if consummated, would result in any person
becoming the beneficial owner of 15 per cent or more of ADT's common shares.
The rights did not become exercisable on account of any person being the
beneficial owner of 15 per cent or more of ADT's common shares when the Plan
was adopted, but become exercisable if such a person increases their
beneficial ownership after that time (note 32(iv)).

                                    F-41


If any person becomes the beneficial owner of 15 per cent or more of ADT's
common shares, or if any person who was already the beneficial owner of 15 per
cent or more of ADT's common shares when the Plan was adopted increases their
beneficial ownership, each right will enable the holder, other than the
acquiring person, to purchase, for the rights purchase price, ADT common
shares having a market value of twice the rights purchase price.

If, following an acquisition of 15 per cent or more of ADT's common shares,
ADT is involved in any mergers or other business combinations or sells or
transfers more than 50 per cent of its assets or earnings power, each right
will entitle the holder to purchase, for the rights purchase price, common
shares, of the other party to such transaction, having a market value of twice
the rights purchase price.

ADT may redeem the rights at a price of $0.01 per right at any time prior to
the specified period of time after a person has become the beneficial owner of
15 per cent or more of ADT's common shares.  The rights will expire in
November 2005 unless exercised or redeemed earlier.

In the event of liquidation of ADT, the holders of all of ADT's convertible
redeemable preference shares are together entitled to payment to them of the
amount for which the preference shares were subscribed and any unpaid
dividends, prior to any payment to the common shareholders.

In March 1991 ADT Finance Inc., an indirect wholly owned Canadian subsidiary
of ADT, issued 1,000,000 non-voting exchangeable shares exchangeable for
common shares of ADT at the option of the holder, at any time, on a one for
one basis.  Holders of non-voting exchangeable shares were entitled only to
dividends equivalent to dividends declared and paid on common shares of ADT.

(ii)    ADT has granted employee share options which are issued under five
fixed share option plans and schemes which reserve common shares for issuance
to the Company's executives and managers.  The majority of options have been
granted under the ADT 1993 Long-Term Incentive Plan ("the Incentive Plan").
The Incentive Plan was originally approved by shareholders of ADT in October
1993 and certain subsequent amendments to the Incentive Plan were approved by
shareholders of ADT in April 1996.  The Incentive Plan is administered by the
remuneration committee of the board of directors of ADT, which consists
exclusively of independent non-executive directors of ADT.  Options are
generally granted to purchase ADT common shares at prices which equate to or
are above the market price of the common shares on the date the option is
granted.  Conditions of vesting are determined at the time of grant.  Certain
options have been granted in which participants were required to pay a
subscription price as a condition of vesting.  Options which have been granted
under the Incentive Plan to date have generally vested and become exercisable
in installments over a three year period from the date of grant and have a
maximum term of ten years.

During 1996 the Company was required to adopt Statement of Financial
Accounting Standards No. 123 "Accounting for Stock-Based Compensation" ("SFAS
123").  SFAS 123 allows companies to measure compensation cost in connection
with executive share option plans and schemes using a fair value based method,
or to continue to use an intrinsic value based method which generally does not
result in a compensation cost.  The Company has decided to continue to use the
intrinsic value based method and no compensation cost has been recorded.  Had
the fair value based method been adopted consistent with the provisions of
SFAS 123, the Company's proforma net (loss) income and proforma net (loss)
income per common share for the years ended December 31, 1996 and 1995 would
have been as follows:

Year ended December 31                                      1996        1995

Net (loss) income-proforma                              ($717.1m)     $17.8m
                                                        --------      ------
Net (loss) income per common share-proforma               ($5.23)      $0.13
                                                        ========      ======

The fair value of each option grant was estimated on the date of grant using
the Black-Scholes option-pricing model with the following weighted average
assumptions.

Expected stock price volatility                 28 per cent
Risk free interest rate                         5.9 per cent
Expected dividend yield                         nil per cent
Expected life of options                        3.7 years

The effects of applying SFAS 123 in this proforma disclosure are not
indicative of future amounts.  SFAS 123 does not apply to awards prior to 1995
and additional awards in future years are anticipated.

(iii)   In April 1992 an issue was made to common shareholders of warrants to
subscribe for ADT common shares on the basis of one warrant for every six
common shares then held.  Each warrant gave the holder the right to subscribe
for one common share at $10.00 per common share during the period from July 1,
1992 to June 30, 1994.  All warrants not exercised at June 30, 1994 have
lapsed in accordance with the terms of the warrants.

The movement in warrants since January 1, 1994 has been as follows:

(iv)    In July 1996, as part of the then agreement to combine with Republic,
ADT granted to Republic a warrant to acquire 15 million common shares of ADT
at an exercise price of $20 per common share.  Following termination of the
agreement to combine with Republic, the warrant vested and was exercisable by
Republic in the six month period commencing September 27, 1996 (note 32(iv)).
In March 1997 the warrant was exercised by Republic and the Company received
$300 million in cash.

(v)     In March 1997 the Company announced that it had entered into a
definitive merger agreement, subject to shareholder approval and other
customary matters, with Tyco International Ltd. ("Tyco"), a United States
quoted company engaged in the manufacture of industrial and commercial
products.  Tyco shareholders will receive one common share in the combined
company for each Tyco common share and ADT shareholders, through a reverse
stock split, will receive 0.48133 common shares in the combined company for
each ADT common share.

The net operating lease rental charge for the year included in the
consolidated statements of income amounted to $77.2 million (1995 - $75.3
million; 1994 - $68.6 million).

(ii)    Financial instruments which potentially subject the Company to
concentrations of credit risk principally consist of cash and cash equivalents
and trade receivables.  The Company places its cash and cash equivalents with
high credit quality financial institutions throughout the world and, by
policy, limits the amount of credit exposure to any one financial institution.
The Company's trade receivables primarily result from its electronic security
services and vehicle auction services businesses and reflects a broad
international customer base.  Credit limits, ongoing credit evaluation and
account monitoring procedures are utilized to minimize the risk of loss.  As a
consequence, concentrations of credit risk are limited.  In addition, the
Vendor Note (note 19) also subjects the Company to credit risk in the event of
non-performance by ITS.  However, the Company currently expects that ITS will
meet its liabilities to the Company under the terms of the Vendor Note.

(iii)   At December 31, 1996 the Company had issued guarantor surety bonds of
$10.0 million (1995 - $10.0 million) to back insurance policies.  These surety
bonds have unlimited duration.

(iv)    In December 1996 Westar Capital, Inc. ("WCI"), a wholly owned
subsidiary of Western Resources, Inc. and a 24 per cent shareholder of ADT,
filed a complaint (as subsequently amended) in the US Courts against ADT and
its directors, among others.  The complaint alleges, among other things, that
ADT and its directors breached their fiduciary duties to WCI and ADT's other
shareholders (a) by adopting the Plan (note 28(iii)), and (b) by issuing to
Republic the warrant (note 30(iv)).  The complaint seeks a court order (a)
directing ADT to redeem the Plan, and (b) declaring the warrant issued to
Republic null and void or preventing ADT and Republic from exercising their
rights under the warrant or preventing Republic from selling or transferring
any of the warrant shares it currently owns.  The complaint also seeks
unspecified damages, attorneys' fees and costs.  Accordingly, an estimate
of any potential loss or range of possible losses, if any, cannot be made.
ADT and its board of directors believe that the allegations in WCI's
complaint against ADT and its directors are without merit and intend to
vigorously defend against them.

                                    F-47


In December 1996 Mr. C. Gachot filed a complaint in the US Courts against ADT
and certain of its directors, among others.  The complaint was brought on
behalf of a class of all shareholders of ADT and alleges, among other things,
that the Plan (note 28(iii)) and the warrant issued to Republic (note 30(iv))
are improper.  The complaint seeks unspecified monetary relief.  Accordingly,
an estimate of any potential loss or range of possible losses, if any, cannot
be made.  ADT and its board of directors believe that the allegations in Mr.
Gachot's complaint against ADT and certain of its directors are without merit
and intend to vigorously defend against them.

In March 1997 Crandon Capital Partners ("CCP") filed a complaint in the US
Courts against ADT and certain of its current and former directors, among
others.  The complaint was brought by CCP in a derivative capacity on behalf
of ADT.  The complaint alleges, among other things, that ADT's directors
breached their fiduciary duties and wasted corporate assets in connection with
(a) the granting of options to certain officers of ADT in 1996, (b) the
implementation of the Plan (note 28(iii)), and (c) the issuance to Republic of
the warrant (note 30(iv)).  The complaint seeks a court order directing ADT's
directors to establish a system of internal controls to prevent repetition of
the alleged breaches of fiduciary duty and corporate waste, and an unspecified
amount of damages.  Accordingly, an estimate of any potential loss or range of
possible losses, if any, cannot be made.  ADT and its directors believe that
the allegations in CCP's complaint against ADT and certain of its directors
are without merit and intend to vigorously defend against them.

The Company is a defendant in a number of other pending legal proceedings
incidental to present and former operations, acquisitions and dispositions.
The Company does not expect the outcome of these proceedings either
individually or in the aggregate to have a material adverse effect on the
consolidated results of operations and cash flows or the consolidated
financial position of the Company.

Note 33 - Pension and other plans

The Company operates various defined benefit pension plans designed in
accordance with conditions and practices in the countries concerned.
Contributions are based on periodic actuarial valuations which use the
projected unit credit method of calculation and are charged to the
consolidated statements of income on a systematic basis over the expected
average remaining service lives of current employees.  The net pension expense
is assessed in accordance with the advice of professionally qualified
actuaries in the countries concerned or is based on subsequent formal reviews
for this purpose.

The Company's United States electronic security services operation has a
non-contributory, funded, defined benefit pension plan covering substantially
all of its employees.

The Company has two contributory, funded, defined benefit pension plans in the
United Kingdom covering substantially all salaried and non-salaried employees.

As a result of the disposal of an interest in European Auctions (notes 7(i)
and 34) a curtailment gain of $2.7 million is included in the net amortization
and deferral component of net pension income for the year ended December 31,
1996.

The actuarial assumptions for the expected long-term rate of return on plan
assets, weighted average discount rate, and rate of increase of future
compensation levels used in determining the actuarial present value of
accumulated benefit obligations for 1996 were 9.5 per cent, 8.5 per cent and
7.0 per cent, respectively (1995 - 9.0 per cent, 8.3 per cent and 6.5 per
cent, respectively).  The actuarial valuations of the United Kingdom plans
were principally carried out by William M. Mercer and by Friends Provident.
The net pension asset at December 31, 1996 is included in other long-term
assets (note 20).

(iii)   The aggregate net pension expense for the year in respect of the
United States and United Kingdom plans amounted to $4.6 million (1995 - $3.1
million; 1994 - $4.3 million).

(iv)    The Company's United States electronic security services operation
sponsors an unfunded defined benefit post-retirement plan which covers both
salaried and non-salaried employees and which provides medical and other
benefits.  This post-retirement health care plan is contributory, with retiree
contributions adjusted annually.

The net post-retirement benefit expense included the following components:

During 1992 the Company adopted amendments to the plan that reduced benefits
attributable to prior service.  These amendments resulted in approximately a
$20 million decrease in the obligation for benefits attributable to prior
service.  This decrease is being amortized as a reduction of plan costs on an
actuarially calculated basis over a period of approximately twenty years
beginning January 1992.  Effective January 1995 the Company implemented a
defined dollar benefit cap for all current and future retirees, regardless of
age.

                                    F-51


The weighted average discount rate used in determining the accumulated
post-retirement benefit obligations was 7.5 per cent (1995 - 7.0 per cent).
The actuarial valuations of the plan were carried out by Kwasha Lipton in 1996
and by Buck Consultants in 1995 and 1994.

Note 34 - Related party transactions

In December 1995 the Company entered into an agreement with Integrated
Transport Systems Limited ("ITS"), a United Kingdom unquoted company, and its
wholly owned subsidiaries Loanoption Limited and ITS Finance Limited, under
which the Company disposed of an interest in European Auctions.

The aggregate consideration received by the Company on closing was comprised
of cash of $235.1 million, $187.6 million Vendor Note (note 18) with an issue
price of $83.9 million and valued by the Company at $74.6 million, $31.1
million Shareholder Loan Notes (note 18) with an issue price of $13.9 million
and valued by the Company at $13.3 million, and a 43.1 per cent interest in
the ordinary share capital of ITS at an issue price of $2.0 million and valued
by the Company at $0.9 million.

In February 1996 the Company disposed of its entire interest in Shareholder
Loan Notes and 33.1 per cent of the ordinary share capital of ITS for an
aggregate cash consideration of $15.4 million (note 18).  As a result, the
Company now holds a 10.0 per cent interest in the ordinary share capital of
ITS, valued and accounted for by the Company at a nominal amount, together
with the Vendor Note which has been accounted for at its amortized cost.

Mr. D.B. Hammond and Mr. T.J. Gibson are both directors of ITS.  Mr. Hammond
was, until April 1996, Deputy Chairman of ADT and Mr. Gibson was the Chief
Executive Officer of ADT Auction Group Limited.

Mr. Hammond and Mr. Gibson subscribed $10.4 million and $0.8 million, in
total, respectively, to  the capital of ITS and, as a result, were interested
in Shareholder Loan Notes with issue prices of $9.4 million and $0.7 million,
respectively, and 22.3 per cent and 1.7 per cent, respectively, of the
ordinary share capital of ITS.  Other senior management and employees of
European Auctions subscribed $3.7 million to the capital of ITS and, as a
group, were interested in Shareholder Loan Notes with an issue price of $3.3
million and 8.0 per cent of the ordinary share capital of ITS.  In addition,
at closing, Mr. M.A. Ashcroft, Chairman and Chief Executive Officer of ADT,
subscribed $7.0 million to the capital of ITS and, as a result, was interested
in Shareholder Loan Notes with an issue price of $6.3 million and 15.0 per
cent of the ordinary share capital of ITS, which interest he continues to
hold.  Mr. Ashcroft is not an officer or director of ITS or any of its
subsidiaries and has no involvement in the day to day management of ITS or any
of its subsidiaries.

Upon the disposal by the Company of an interest in European Auctions, ADT
share options held by directors and employees of European Auctions became
immediately exercisable.  ADT entered into arrangements with Mr. Gibson under
which share options held by him at the time of the disposal by the Company of
an interest in European Auctions were purchased by ADT for an aggregate
economic value totalling $1.2 million, based on ADT's common share price on
December 19, 1995, of which Mr. Gibson invested $0.8 million in the capital of
ITS, referred to above.  ADT also entered into similar arrangements with other
senior management and employees of European Auctions under which ADT purchased
share options held by them for an aggregate economic value totalling $0.6
million, in order to enable them to invest in the capital of ITS.  In
addition, in order to further enable Mr. Hammond to invest in the capital of
ITS, ADT purchased from him share options with an aggregate economic value
totalling $1.1 million, based on ADT's common share price on December 19,
1995, which would otherwise have been exercisable in March 1996.

                                    F-52


Upon the disposal by the Company of an interest in European Auctions, Mr.
Gibson received a severance payment of $0.3 million and other senior
management and employees of European Auctions, as a group, received severance
payments totalling $0.4 million.

A company controlled by Mr. Ashcroft made non-collateralized loans to Mr.
Hammond, or companies controlled by him, of an aggregate of $7.8 million,
solely for the purpose of enabling Mr. Hammond or these companies to invest in
the capital of ITS.

The cash consideration paid to the Company on closing was obtained by the ITS
group through the subscription of $26.5 million in the capital of ITS and
approximately $209.7 million through the drawdown of sterling term loans under
a bank credit agreement entered into between the ITS group and a group of
banks.  The bank credit agreement has a term of seven years and obligations
thereunder are guaranteed and collateralized by a first priority pledge of the
shares and assets of all the companies comprising European Auctions and the
ITS group.

At closing, the Company entered into an agreement with the ITS group whereby
the Company granted to ITS and its subsidiaries permission to use the ADT name
and certain trademarks for a period of up to three years for a total cash
consideration, paid at closing, of $0.6 million.

At closing, the Company entered into an option agreement with Mr. Ashcroft
which, if exercised, would have required Mr. Ashcroft to purchase from the
Company, for cash fifty days after closing, Shareholder Loan Notes with an
issue price of up to $8.2 million and up to 19.6 per cent of the ordinary
share capital of ITS.  In addition, at closing, ITS entered into an agreement
with the Company and Mr. Ashcroft under which ITS agreed to use its reasonable
efforts, for a forty-five day period after closing, to find unrelated third
party investors to purchase Shareholder Loan Notes and ordinary share capital
of ITS from the Company and Mr. Ashcroft, and under which the Company and Mr.
Ashcroft agreed to certain voting restrictions in respect of their holdings of
the  ordinary share capital of ITS as described below.  In February 1996 the
Company and Mr. Ashcroft agreed that the mutual obligations under the option
agreement be released.

At December 31, 1995 the Company's investment in the ordinary share capital of
ITS was accounted for as an unconsolidated subsidiary under temporary control,
due to an agreement between ITS, the Company and Mr. Ashcroft limiting the
voting rights of each of the Company and Mr. Ashcroft to 15.0 per cent of the
voting rights of ITS and due to the fact that Mr. Hammond did not be seek
re-election to the board of directors of ADT at the 1996 annual general
meeting.  Accordingly, at December 31, 1995 the equity method of accounting
was used in the consolidated financial statements, and the Vendor Note and
Shareholder Loan Notes were accounted for at their amortized cost.

An opinion regarding the fair value of the transactions described above was
provided to the independent non-executive directors of ADT by a leading
European investment banking firm and the transactions were approved
unanimously by the independent non-executive directors of ADT.

As a consequence of the Re-Engineering Project, and incorporating the effects
of the acquisition of Alert, in each of the fourth quarters of 1996 and 1995
senior executive management approved a restructuring plan which resulted in a
charge for restructuring and other non-recurring items of $131.6 million and
$19.4 million, respectively (note 5(i)).  The effects of the Re-Engineering
Project resulted in a charge for restructuring and other non-recurring items
at the corporate level in 1996 of $0.5 million (note 5(ii)).

(a)     In February 1996 ADT Operations acquired the remaining 24.0 per cent
of the outstanding voting share capital of Alert, an electronic security
services company, not already owned by ADT Operations, for an aggregate cash
consideration of $25.5 million, which was financed from cash on hand.  The
amount of goodwill arising from this acquisition was $10.3 million.  During
1996 ADT Operations purchased other intangibles, principally customer
contracts, for an aggregate cash consideration of $4.1 million which was
financed from cash on hand.  In December 1996 ADT Operations acquired the
electronic security services business and net assets of an affiliate for an
aggregate consideration of $70.0 million which was financed through a
long-term loan from an affiliate.  The amount of goodwill arising from this
acquisition was $5.4 million.


In December 1995 ADT Operations acquired 76.0 per cent of the outstanding
voting share capital of Alert, for an aggregate cash consideration of $69.0
million, which was financed from $54.0 million of cash on hand and through a
long-term loan from affiliates of $15.0 million.  The amount of goodwill and
other intangibles arising from this acquisition was $80.1 million and $40.0
million, respectively.  During 1995 ADT Operations also acquired several small
electronic security services businesses for an aggregate cash consideration of
$0.9 million.

These acquisitions have been accounted for using the purchase method.
Accordingly, the respective purchase prices have been allocated to assets
acquired and liabilities assumed based on their preliminary estimated fair
values.  These allocations resulted in goodwill and other intangibles of $19.8
million arising during the year (1995 - $121.0 million).

                                    F-69


(b)     During 1996, ADT Operations disposed of certain of its customer
contracts to an affiliate.  The aggregate cash consideration on disposal
amounted to $74.5 million and the net gain on disposal of $36.3 million was
included in other income less expenses (note (vi)).  In December 1996 ADT
Operations disposed of certain of its electronic security services operations
(Sonitrol franchises) to an affiliate.  The net unamortized goodwill and other
intangibles on disposal of $1.8 million was included in the gain on disposal
of businesses to affiliates (note (iv)).

(c)     The accumulated cost, accumulated amortization and net book values of
the goodwill balance included within goodwill and other intangibles at
December 31, 1996 amounted to $385.7 million, $39.1 million and $346.6
million, respectively (1995 - $801.2 million, $142.8 million and $658.4
million, respectively).

Note (xiv)  - Long-term notes receivable - affiliates

In September 1996 ADT Operations subscribed for $73.8 million aggregate
principal amount at maturity of subordinated deep discount zero coupon loan
notes issued by an affiliate maturing in September 2001.  There are no
periodic payments of interest.  The notes were issued at a price of $50.0
million, reflecting a yield to maturity of 7.9 per cent per annum.  ADT
Operations funded the subscription through loans drawn down under the revolving

During 1994 ADT Operations assigned its interest in its trademarks, service
marks and associated goodwill to an affiliate for an aggregate consideration
of $150.0 million.  In view of the fact that the assignment was to an
affiliate, and taking into account the terms of the transaction, the net gain
of $141.7 million arising on the assignment was deferred.  During 1996 $12.4
million (1995 - $11.9 million) of this deferred gain was credited to the
consolidated statements of income to offset license fee payments made by ADT
Operations to the affiliate, calculated as a fixed percentage of net sales,
for use of the trademarks and service marks referred to above.

(b)     Financial instruments which potentially subject ADT Operations to
concentrations of credit risk principally consist of cash and cash equivalents
and trade receivables.  ADT Operations places its cash and cash equivalents
with high credit quality financial institutions and, by policy, limits the
amount of credit exposure to any one financial institution.  ADT Operations'
trade receivables primarily result from its electronic security services and
vehicle auction services businesses and reflects a broad customer base.
Credit limits, ongoing credit evaluation and account monitoring procedures are
utilized to minimize the risk of loss.  As a consequence, concentrations of
credit risk are limited.

(c)     ADT Operations is a defendant in a number of pending legal proceedings
incidental to present and former operations, acquisitions and dispositions.
ADT Operations does not expect the outcome of these proceedings either
individually or in the aggregate to have a material adverse effect on the
consolidated results of operations and cash flows or the consolidated
financial position of ADT Operations.

Note (xxv) - Pension and other plans

(a)     ADT Operations' United States electronic security services operation
has a non-contributory, funded, defined benefit pension plan covering
substantially all of its employees.  Details of this pension plan are provided
in note 33(i).

(b)     ADT Operations' United States electronic security services operation
sponsors an unfunded defined benefit post-retirement plan which covers both
salaried and non-salaried employees and which provides medical and other
benefits.  Details of this post-retirement plan are provided in note 33(iv).

       THIS CREDIT AGREEMENT, dated as of January 9, 1997, among ADT
OPERATIONS, INC., a Delaware corporation (the "Borrower"), the various
financial institutions as are or may become parties hereto (collectively, the
"Lenders"), and THE BANK OF NOVA SCOTIA ("Scotiabank"), individually and as

       WHEREAS, in connection with the extensions of credit contemplated
hereunder, the Borrower desires to replace that certain Existing Credit
Facility (as hereinafter defined);

       WHEREAS, the Borrower has requested the Lenders and the Issuers (as
hereinafter defined) to extend commitments to replace the Existing Credit
Facility and to provide financing for general corporate purposes; and

       WHEREAS, the Lenders and the Issuers are willing, on the terms and
subject to the conditions hereinafter set forth (including Article VI), to
extend such commitments and to make loans and issue and participate in letters
of credit pursuant thereto;

       NOW, THEREFORE, the parties hereto agree as follows:


                                   ARTICLE I

                       DEFINITIONS AND ACCOUNTING TERMS

shall, except where the context otherwise requires, have the following
meanings (such meanings to be equally applicable to the singular and plural
forms thereof):

       "ADT Automotive" means ADT Automotive Holdings, Inc. (formerly known as
ADT Auctions, Inc.), a Delaware corporation and Wholly Owned Subsidiary of the
Borrower.

       "ADT Finance Inc." means ADT Finance Inc., a Canadian corporation.

       "ADT Limited" means ADT Limited, a company organized under the laws of
Bermuda.

Limited pursuant to clause (a) of Section 6.1.4, substantially in the form of
Exhibit I hereto, as amended, supplemented, amended and restated or otherwise
modified from time to time.

       "ADT Security Services" means ADT Security Services, Inc. (formerly
known as ADT Security Systems, Inc.), a Delaware corporation.

       "Affiliate" of any Person means any other Person which, directly or
indirectly, controls, is controlled by or is under common control with such
Person (excluding any trustee under, or any committee with responsibility for
administering, any Plan).  A Person shall be deemed to "control" another
Person if such Person possesses, directly or indirectly, power

             (a)     to vote 10% or more of the securities (on a fully diluted
       basis) having ordinary voting power for the election of directors or
       managing general partners; or

             (b)     to direct or cause the direction of the management and
       policies of such other Person whether by contract or otherwise.

       "Agent" is defined in the preamble and includes each other Person as
shall have subsequently been appointed as a successor Agent pursuant to
Section 10.4.

       "Agreement" means, on any date, this Credit Agreement as originally in
effect on the Effective Date and as thereafter from time to time amended,
supplemented, amended and restated or otherwise modified and in effect on such
date.

       "Alternate Base Rate" means, on any date and with respect to all Base
Rate Loans, a fluctuating rate of interest per annum (rounded upwards, if
necessary, to the next 1/16 of 1%) equal to the higher of

             (a)     the Prime Rate in effect for such day; and

             (b)     the Federal Funds Effective Rate in effect for such day
       plus 1/2 of 1%.

For purposes hereof:

             "Federal Funds Effective Rate" means, for any day, a fluctuating
       rate of interest per annum equal to the weighted average of the rates
       on overnight Federal funds transactions with members of the Federal
       Reserve System arranged by Federal funds brokers, as published on the
       succeeding Business Day by the Federal Reserve Bank of New York, or, if
       such rate is not so published for any day which is a Business Day, the
       average of the quotations for the day of such transactions received by
       the Agent from three Federal funds brokers of recognized standing
       selected by it.

             "Prime Rate" means the rate of interest per annum publicly
       announced by the Agent from time to time as its prime rate in effect at
       its principal office in New York City.  The Prime Rate is not intended
       to be the lowest rate of interest charged by the Agent in connection
       with extensions of credit to debtors.

If for any reason the Agent shall have determined (which determination shall
be conclusive absent manifest error) that it is unable to ascertain the
Federal Funds Effective Rate for any reason, including the inability or
failure of the Agent to obtain sufficient quotations in accordance with the
terms hereof, the Alternate Base Rate shall be determined without regard to
clause (b) until the circumstances giving rise to such inability no longer
exist.  Any change in the Alternate Base Rate due to a change in the Prime
Rate or the Federal Funds Effective Rate shall be effective as of the opening
of business on the date of such change.

       "ASH" means Automated Security (Holdings) PLC.

       "ASH Acquisition Date" means September 6, 1996.

       "Asset Sale" is defined in Section 4.2.10 of the ADT Limited Guaranty.

       "Assignee Lender" is defined in Section 11.11.1.

       "Auction Business Intercompany Debt" means, with respect to any

pursuant to such Permitted Auction Business Sale or any Subsidiary of any such
Subsidiary) by any Subsidiary of the Borrower the Capital Stock of which, or
all or substantially all of the assets of which, are sold pursuant to a
Permitted Auction Business Sale.

       "Authorized Officer" means, relative to any Obligor, those of its
officers whose signatures and incumbency shall have been certified to the
Agent and the Lenders pursuant to Section 6.1.1.

       "Base Rate Loan" means a Loan bearing interest at a fluctuating rate
determined by reference to the Alternate Base Rate.

Loan Borrowing or a Revolving Loan Borrowing.

       "Borrowing Request" means, as the context may require, either a
Revolving Loan Borrowing Request or a Competitive Bid Loan Borrowing Request.

       "Business Day" means any day

             (a)     which is neither a Saturday or Sunday nor a legal holiday
       on which banks are authorized or required to be closed in New York City
       and

             (b)     relative to the making, continuing, prepaying or repaying
       of any LIBO Rate Loans, on which dealings in Dollars are carried on in
       the London interbank market.

       "Capital Expenditures" means, with respect to any Person for any
period, the sum (without duplication) of

             (a)     the excess of (i) the aggregate amount of all
       expenditures of such Person and its Subsidiaries for fixed or capital
       assets made during such period which, in accordance with GAAP, would be
       classified as capital expenditures over (ii) the aggregate amount of
       net cash proceeds of Excluded Dispositions received by the Borrower,
       ADT Limited or any other Subsidiary of ADT Limited during such period;

plus

             (b)     the aggregate amount of all Capitalized Lease Liabilities
       of such Person incurred during such period;

provided, however, that the Capital Expenditures of any Person for any period
that would include a Pre-Acquisition Period will not include any Capital
Expenditures made by ASH or any of its Subsidiaries during such
Pre-Acquisition Period.

       "Capital Stock" means, with respect to any Person, any and all shares,
interests, participations or other equivalents (however designated) of such

       "Capitalized Lease Liabilities" means, with respect to any Person, all
monetary obligations of such Person or any of its Subsidiaries under any
leasing or similar arrangement which, in accordance with GAAP, would be

amount thereof, determined in accordance with GAAP, and the stated maturity
thereof shall be the date of the last payment of rent or any other amount due
under such lease prior to the first date upon which such lease may be
terminated by the lessee without payment of a penalty.

       "Cash Equivalent Investment" means, at any time:

             (a)     any evidence of Indebtedness, with a maturity of 180 days
       or less, issued or directly and fully guaranteed by the United States
       Government;

City time) on the third Business Day prior to the proposed date of borrowing.
Each Competitive Bid Loan Offer shall specify

             (i)  the proposed date of Borrowing, which shall be the same as
       that set forth in the applicable Invitation for Bid Loan Offers,

             (ii)  the principal amount of the Competitive Bid Loan which the
       Lender submitting such Competitive Bid Loan Offer would be willing to
       make as part of such proposed Competitive Bid Loan Borrowing (which
       amount shall be in a minimum principal amount of $5,000,000 and in an
       integral multiple of $1,000,000 and which amount may exceed such
       Lender's Percentage of the Revolving Loan Commitment Amount),

             (iii)  the LIBO Rate Bid Margin therefor, and

             (iv)  the identity of the quoting Lender;

provided, however, that any Competitive Bid Loan Offer submitted by a Lender
pursuant to this Section 2.3.3 shall be irrevocable, unless otherwise
consented to in writing by the Agent acting upon the instructions of the
Borrower.

       (b)   Any Competitive Bid Loan Offer that:

             (i)  is not substantially in the form of Exhibit D-2 hereto or
       does not specify all of the information required in this Section 2.3.3;

             (ii)  contains qualifying, conditional or similar language;

             (iii)  contains proposed terms other than or in addition to those
       set forth in the applicable Invitation for Bid Loan Offers; or

             (iv)  arrives after the time set forth in this Section 2.3.3

shall be disregarded by the Agent.

       SECTION 2.3.4.  Notice to Borrower.  The Agent shall (by telephone,
promptly confirmed in writing) notify the Borrower of the terms of any
Competitive Bid Loan Offer submitted by a Lender that is in accordance with
Section 2.3.3 with all due haste after the receipt thereof.  The Agent's
notice to the Borrower shall specify (a) the aggregate principal amount of
Competitive Bid Loans for which Competitive Bid Loan Offers have been received
in accordance with the terms specified in the related Competitive Bid Loan
Borrowing Request, (b) the respective principal amounts and LIBO Rate Bid
Margins so offered, and (c) the identity of such quoting Lenders.

       SECTION 2.3.5.  Competitive Bid Loan Acceptance.  The Borrower shall,
before 11:00 a.m. (New York City time) on the third Business Day prior to the
proposed date of such proposed Competitive Bid Loan Borrowing, either

             (a)     irrevocably cancel the Competitive Bid Loan Borrowing
       Request that requested such Competitive Bid Loan Borrowing by giving
       the Agent telephonic notice, promptly confirmed in writing (and the
       Agent shall promptly so notify each of the Lenders) to that effect
       (and, for purposes of this Section, a failure on the part of the
       Borrower to timely notify the Agent under the terms of this clause
       shall be deemed to be non-acceptance of all Competitive Bid Loan Offers
       so notified to the Borrower pursuant to Section 2.3.4), or

             (b)     (i) irrevocably accept, in whole or in part, one or more
       of the Competitive Bid Loan Offers made by any Lender or Lenders
       pursuant to Section 2.3.3, in its sole discretion, by giving the Agent
       telephonic notice (promptly confirmed in writing by delivery to the
       Agent of a Competitive Bid Loan Acceptance), and the Agent shall,
       promptly upon receiving such telephonic notice from the Borrower,
       notify each Lender whose Competitive Bid Loan Offer has been accepted,
       in whole or in part, of (A) the amount of the Competitive Bid Loan
       Borrowing to be made on such date, and (B) the amount of the
       Competitive Bid Loan (which amount shall not be greater than the amount
       offered by such Lender for such Competitive Bid Loan pursuant to
       Section 2.3.3) to be made by such Lender as part of such Competitive
       Bid Loan Borrowing, and (ii) irrevocably reject any remaining
       Competitive Bid Loan Offers made by Lenders pursuant to Section 2.3.3
       by giving the Agent telephonic notice, promptly confirmed in writing
       (and the Agent shall promptly so notify the Lenders) to that effect;
       provided, however, that

                 (A)  the Borrower shall not accept an offer made at a
             particular Competitive Bid Rate if the Borrower has decided to
             reject an offer made in respect of the same Competitive Bid Loan
             Borrowing with the same Competitive Bid Loan Maturity Date and a
             lower Competitive Bid Rate,

                 (B)  the aggregate principal amount of the Competitive Bid
             Loan Offers accepted by the Borrower shall not exceed the
             principal amount specified in the Competitive Bid Loan Borrowing
             Request therefor,

                 (C)  if the Borrower shall accept an offer or offers made at
             a particular Competitive Bid Rate but the amount of such offer or
             offers shall cause the total amount of offers to be accepted by
             the Borrower to exceed the amount specified in the Competitive Bid
             Loan Borrowing Request therefor, then the Borrower shall

                     (1) accept a portion of such offer or offers in an
                 aggregate amount equal to the amount specified in the
                 Competitive Bid Loan Borrowing Request less the amount of all
                 other offers accepted with respect to such Competitive Bid
                 Loan Borrowing Request, and

                     (2) allocate the Competitive Bid Loans in respect of
                 which such offers are accepted among the Lenders submitting
                 such offers as nearly as possible in proportion to the
                 aggregate amount of such offers made by each Lender
                 (provided, that if the available principal amount of
                 Competitive Bid Loans to be so allocated is not sufficient to
                 enable Competitive Bid Loans to be so allocated to each such
                 Lender in a minimum principal amount of $5,000,000, the
                 number of such Lenders shall be reduced by the Agent by lot
                 until the Competitive Bid Loans to be made by such remaining
                 Lenders would be in a principal amount of $5,000,000 or an
                 integral multiple of $1,000,000 in excess thereof),

                 (D)  no bid shall be accepted for a Competitive Bid Loan
             unless such Competitive Bid Loan is in a minimum principal amount
             of $5,000,000 and an integral multiple of $1,000,000 and is part
             of a Competitive Bid Loan Borrowing in a minimum principal amount
             of $5,000,000, and

                 (E)  the Borrower may not accept any offer that is described
             in clause (b) of Section 2.3.3 or that otherwise fails to comply
             with the requirements of this Agreement.

       A notice given by the Borrower pursuant to this clause (b) of this
       Section 2.3.5 shall be irrevocable.

       SECTION 2.3.6.  Funding of Competitive Bid Loans.  Not later than 12:00
noon (New York City time) on the date specified for each Competitive Bid Loan
Borrowing hereunder, each Lender participating therein shall deposit with the
Agent same day funds in the amount of the Competitive Bid Loan to be made by
it on such date.  Such deposit will be made to an account which the Agent
shall specify from time to time by notice to the Lenders.  The amount so
received by the Agent shall be made available to the Borrower by wire transfer
to the accounts the Borrower notified to the Agent in writing.  As soon as
practicable after the Competitive Bid Loan Borrowing, the Agent shall notify
each Lender of the amount of the Competitive Bid Loan Borrowing, the
applicable Competitive Bid Rates accepted, the consequent Competitive Bid
Outstanding Balance, the date on which such Competitive Bid Loan Borrowing was
made and the corresponding Competitive Bid Loan Maturity Date applicable to
all Competitive Bid Loans that are part of such Competitive Bid Loan Borrowing.

       SECTION 2.4.  Continuation and Conversion Elections.  By delivering a
Continuation/Conversion Notice to the Agent on or before 10:00 a.m., New
York City time, on a Business Day, the Borrower may from time to time
irrevocably elect, on not less than three nor more than five Business Days'
notice that all, or any portion in an aggregate minimum amount of
$5,000,000 and an integral multiple of $1,000,000, of any Revolving Loans
be, in the case of Revolving Loans which are Base Rate Loans, converted
into Revolving Loans which are LIBO Rate Loans or, in the case of Revolving
Loans which are LIBO Rate Loans, be converted into Revolving Loans which
are Base Rate Loans or continued as Revolving Loans which are LIBO Rate
Loans (in the absence of delivery of a Continuation/Conversion Notice with
respect to any Revolving Loan which is a LIBO Rate Loan at least three
Business Days before the last day of the then current Interest Period with
respect thereto, such Revolving Loan which is a LIBO Rate Loan shall, on
such last day, automatically convert to a Revolving Loan which is a Base
Rate Loan); provided, however, that (i) each such conversion or
continuation shall be pro rated among the applicable outstanding Revolving
Loans of all Lenders, and (ii) no portion of the outstanding principal
amount of any Revolving Loans may be continued as, or be converted into,
LIBO Rate Loans when any Event of Default has occurred and is continuing.

       SECTION 2.5.  Funding.  Each Lender may, if it so elects, fulfill its
obligation to make, continue or convert LIBO Rate Loans hereunder by causing
one of its foreign branches or  Affiliates or an international banking
facility created by such Lender to make or maintain such LIBO Rate Loan to the
extent such branch, Affiliate or banking facility has complied, if applicable,
with the provisions of the last paragraph of Section 5.6 as if such branch,
Affiliate or banking facility were a Lender hereunder; provided, however, that
such LIBO Rate Loan shall nonetheless be deemed to have been made and to be
held by such Lender, and the obligation of the Borrower to repay such LIBO
Rate Loan shall nevertheless be to such Lender for the account of such foreign
branch, Affiliate or international banking facility.  In addition, the
Borrower hereby consents and agrees that, for purposes of any determination to
be made for purposes of Section 5.1, 5.2, 5.3 or 5.4, it shall be conclusively
assumed that each Lender elected to fund all LIBO Rate Loans by purchasing
Dollar deposits in its LIBOR Office's interbank eurodollar market; provided,
however, that nothing in this sentence shall affect the provisions in Article
V to the extent that such Article provides that amounts to be reimbursed by
the Borrower are to be determined on the basis of actual costs and actual
reductions incurred by one or more Lenders.

       SECTION 2.6.  Notes.  (a)  Each Lender's Revolving Loans shall be
evidenced by a Revolving Note payable to the order of such Lender in a maximum
principal amount equal to such Lender's Percentage of the original Revolving
Loan Commitment Amount.

       (b)  Each Lender's Competitive Bid Loans shall be evidenced by a
Competitive Bid Loan Note payable to the order of such Lender in a maximum
principal amount equal to the original Revolving Loan Commitment Amount.

       (c)  The Borrower hereby irrevocably authorizes each Lender to make (or
cause to be made) appropriate notations on the grid attached to such Lender's
Notes (or on any continuation of such grid), which notations, if made, shall
evidence, inter alia, the date of, the outstanding principal amount of, and
the Interest Period (in the case of Revolving Loans), or the Competitive Bid
Loan Maturity Dates and the Competitive Bid Loan Interest Payment Dates (in
the case of Competitive Bid Loans) applicable to the Loans evidenced thereby.
Such notations shall, to the fullest extent permitted under applicable law, be
conclusive and binding on the Borrower absent manifest error; provided,
however, that the failure of any Lender to make any such notations shall not
limit or otherwise affect any Obligations of the Borrower or any other Obligor.


                                  ARTICLE III

                  REPAYMENTS, PREPAYMENTS, INTEREST AND FEES

       SECTION 3.1.  Repayments and Prepayments.  The Borrower shall repay in
full the unpaid principal amount of each Revolving Loan on the Stated Maturity
Date and shall repay in full the unpaid principal amount of each Competitive
Bid Loan on the Competitive Bid Loan Maturity Date thereof.  Prior to such
Stated Maturity Date or such Competitive Bid Loan Maturity Date, as the case
may be, repayments and prepayments of Loans shall be made as set forth in this
Section 3.1.  Each prepayment of any Loans made pursuant to this Section shall
be without premium or penalty, except as may be required by Section 5.4.

       SECTION 3.1.1.  Voluntary Prepayments.

       SECTION 3.1.1.1.  Revolving Loans.  From time to time on any Business
Day, the Borrower may make a voluntary prepayment, in whole or in part, of the
outstanding principal amount of any Revolving Loans, and may cash
collateralize, in whole or part, outstanding Letters of Credit; provided,
however, that

             (a)     any such prepayment shall be made pro rata among
       Revolving Loans of the same type and, if applicable, having the same
       Interest Period of all Lenders;

             (b)     all such voluntary prepayments shall require at least
       three (in the case of Revolving Loans which are LIBO Rate Loans) or one
       (in the case of Revolving Loans which are Base Rate Loans), but no more
       than five (in the case of any Revolving Loans), Business Days' prior
       written notice to the Agent;

             (c)     all such voluntary partial prepayments shall be in an
       aggregate minimum amount of $5,000,000 and an integral multiple of
       $1,000,000 or in the aggregate principal amount of all Revolving Loans
       of the same type and, in the case of Revolving Loans which are LIBO Rate
       Loans, having the Interest Period of the Revolving Loans being prepaid;
       and

             (d)     no voluntary prepayment of principal of any Revolving
       Loan shall cause a reduction in the Revolving Loan Commitment Amount.

       SECTION 3.1.1.2.  Competitive Bid Loans.  The Borrower shall have no
right to prepay, in whole or in part, the outstanding principal amount of any
Competitive Bid Loan, unless (i) the Lender that has made such Competitive Bid
Loan otherwise consents in writing or (ii) such Competitive Bid Loan is
accruing interest at such time at a rate determined on the basis of the
Alternate Base Rate pursuant to Section 5.1.  Any Competitive Bid Loan may be
prepaid in whole or in part in amounts of at least $5,000,000 or any larger
integral multiple of $1,000,000 in excess thereof at any time at which such
Competitive Bid Loan shall bear interest at a rate determined on the basis of
the Alternate Base Rate pursuant to Section 5.1.

       SECTION 3.1.2.  Mandatory Prepayments.  The Borrower shall make
mandatory prepayments as set forth in this Section 3.1.2.  Each mandatory
prepayment under this Section 3.1.2 shall be applied in accordance with the
terms of this Section 3.1.2.

       SECTION 3.1.2.1.  Mandatory Prepayment Upon Commitment Reduction.  The
Borrower shall, on each date when any reduction in the Revolving Loan
Commitment Amount shall become effective, including pursuant to Section 2.1.4,
make a mandatory prepayment (which shall be applied (or held for application,
as the case may be) by the Lenders first to the payment of the aggregate unpaid
principal amount of the Loans then outstanding, and then to the payment and/or
cash collateralization of the then outstanding Letter of Credit Outstandings)
equal to the excess, if any, of the aggregate, outstanding principal amount of
all Loans and Letter of Credit Outstandings over the Revolving Loan Commitment
Amount as so reduced; provided, however, that if (and to the extent) on the
date of any prepayment required under this Section 3.1.2.1 a LIBO Rate Loan
would otherwise be required to be prepaid on a day other than the last day of
the then current Interest Period (or, in the case of a Competitive Bid Loan,
the Competitive Bid Loan Maturity Date applicable thereto) with respect to
such Loan (after prepaying any Revolving Loans then outstanding that are Base
Rate Loans), the Borrower may (in the case of LIBO Rate Loans which are
Revolving Loans) or shall (in the case of Competitive Bid Loans) defer such
prepayment with respect to such LIBO Rate Loan until, in the case of a LIBO
Rate Loan which is a Revolving Loan, the last day of the then current Interest
Period with respect to such LIBO Rate Loan or, in the case of a Competitive
Bid Loan, the Competitive Bid Loan Maturity Date applicable thereto.

       SECTION 3.1.2.2.  Acceleration of Scheduled Maturity.  The Borrower
shall, immediately upon any acceleration of the Stated Maturity Date or
Competitive Bid Loan Maturity Date of any Loans pursuant to Section 9.2 or
Section 9.3, repay all Loans, unless, pursuant to Section 9.3, only a portion
of all Loans is so accelerated, in which case the Borrower shall repay such
Loans so accelerated.

       SECTION 3.2.  Interest Provisions.  Interest on the outstanding
principal amount of Loans shall accrue and be payable in accordance with this
Section 3.2.

       SECTION 3.2.1.  Rates.  (a) Pursuant to an appropriately delivered
Borrowing Request or Continuation/Conversion Notice, the Borrower may
elect that Revolving Loans comprising a Revolving Loan Borrowing accrue
interest at a rate per annum:

             (i)  on that portion maintained from time to time as a Base Rate
       Loan, equal to the Alternate Base Rate from time to time in effect; and

             (ii)  on that portion maintained as a LIBO Rate Loan, during each
       Interest Period applicable thereto, equal to the sum of the LIBO Rate
       (Reserve Adjusted) for such Interest Period plus the applicable LIBO
       Rate Margin.

       The "LIBO Rate (Reserve Adjusted)" means, relative to any Loan to be
made, continued or maintained as, or converted into, a LIBO Rate Loan for any
Interest Period, a rate per annum (rounded upwards, if necessary, to the
nearest 1/16 of 1%) determined pursuant to the following formula:

          LIBO Rate         =                 LIBO Rate
                                   -------------------------------
       (Reserve Adjusted)          1.00 - LIBOR Reserve Percentage

The LIBO Rate (Reserve Adjusted) for any Interest Period for any LIBO Rate
Loan will be determined by the Agent on the basis of the LIBOR Reserve
Percentage in effect on, and the applicable rates furnished to and received by
the Agent from the Reference Lender or Reference Lenders, as the case may be,
two Business Days before the first day of such Interest Period, subject,
however, to the provisions of Section 3.2.4.

       "LIBO Rate" means, relative to any Interest Period for any LIBO Rate
Loan, the rate of interest equal to the average (rounded upwards, if
necessary, to the nearest 1/16 of 1%) of the rates per annum at which Dollar
deposits in immediately available funds are offered to each Reference Lender's
LIBOR Office in the London interbank market as at or about 11:00 a.m. London
time two Business Days prior to the beginning of such Interest Period for
delivery on the first day of such Interest Period, and in an amount
approximately equal to the amount of each such Reference Lender's LIBO Rate
Loan (in the case of a LIBO Rate Loan which is a Revolving Loan) or the amount
of the Competitive Bid Loan Borrowing of which such LIBO Rate Loan is a part
(in the case of a LIBO Rate Loan which is a Competitive Bid Loan) and for a
period approximately equal to such Interest Period.

       "LIBOR Reserve Percentage" means, relative to any Interest Period for
any LIBO Rate Loan, the reserve percentage (expressed as a decimal) equal to
the maximum aggregate reserve requirements (including all basic, emergency,
supplemental, marginal and other reserves and taking into account any
transitional adjustments or other scheduled changes in reserve requirements)
specified under regulations issued from time to time by the F.R.S. Board and
then applicable to liabilities consisting of and including "Eurocurrency
Liabilities", as currently defined in Regulation D of the F.R.S. Board.

       (b)  Each Competitive Bid Loan shall accrue interest at a rate per
annum equal to the Competitive Bid Rate specified by the Lender making such
Competitive Bid Loan in its Competitive Bid Loan Offer with respect thereto
delivered pursuant to Section 2.3.3 above and accepted by the Borrower
pursuant to Section 2.3.5.

       (c)  All LIBO Rate Loans shall bear interest from and including the
first day of the applicable Interest Period to (but not including) the last
day of such Interest Period at the interest rate determined as applicable to
such LIBO Rate Loan for such Interest Period.

       SECTION 3.2.2.  Post-Maturity Rates.  After the date any principal
amount of any Loan is due and payable (whether on the Stated Maturity Date,
upon acceleration or otherwise), or after any other monetary Obligation of the
Borrower shall have become due and payable, the Borrower shall pay, but only
to the extent permitted by law, interest (after as well as before judgment) on
such amounts at a rate per annum equal to the Alternate Base Rate plus a
margin of 2.0% (or, to the extent any such amounts constitute principal in
respect of any LIBO Rate Loan, at a rate per annum equal to the LIBO Rate
(Reserve Adjusted) with respect thereto plus a margin of 2.0% plus the LIBO
Rate Margin (or, in the case of Competitive Bid Loans, plus (or minus) the
applicable LIBO Rate Bid Margin) applicable to such amounts for the remaining
period of the applicable Interest Period then in effect).

       SECTION 3.2.3.  Payment Dates.  Interest accrued on each Loan shall be
payable, without duplication:

             (a)     in the case of any Revolving Loan, on the Stated Maturity
       Date therefor;

             (b)     on any portion of the principal amount of any Loan that
       is voluntarily or mandatorily paid or prepaid, on the date of such
       voluntary or mandatory payment or prepayment;

             (c)     with respect to Revolving Loans which are Base Rate
       Loans, on each Quarterly Payment Date occurring after the Effective
       Date;

             (d)     with respect to Revolving Loans which are LIBO Rate
       Loans, on the last Business Day of each applicable Interest Period
       (and, if such Interest Period shall exceed three months, on each three
       (and integral of three) month anniversary of the making of such LIBO
       Rate Loan);

             (e)     with respect to any Revolving Loans which are Base Rate
       Loans converted into Revolving Loans which are LIBO Rate Loans on a day
       when interest would not otherwise have been payable pursuant to clause
       (c), on the date of such conversion;

             (f)     with respect to Competitive Bid Loans, on each
       Competitive Bid Loan Maturity Date and, with respect to Competitive Bid
       Loans with a Competitive Bid Loan Maturity Date in excess of three
       months after the date such Competitive Bid Loan is made, on each three
       (and integral of three) month anniversary of the making of such
       Competitive Bid Loan (each such date (including each Competitive Bid
       Loan Maturity Date), a "Competitive Bid Loan Interest Payment Date");
       and

             (g)     on that portion of any Loans the Stated Maturity Date of
       which (or, in the case of any Competitive Bid Loans, the Competitive
       Bid Loan Maturity Date of which) is accelerated pursuant to Section 9.2
       or Section 9.3, immediately upon such acceleration.

Interest accrued on Loans or other monetary Obligations arising under this
Agreement or any other Loan Document after the date such amount is due and
payable (whether on the Stated Maturity Date, upon acceleration or otherwise)
shall be payable upon demand.

       SECTION 3.2.4.  Interest Rate Determination.  Each Reference Lender
agrees to furnish to the Agent timely information for the purpose of
determining each LIBO Rate.  If any one or more of the Reference Lenders shall
fail timely to furnish such information to the Agent for any such interest
rate, the Agent shall determine such interest rate on the basis of the
information furnished by the remaining Reference Lenders.

       SECTION 3.3.  Fees.  The Borrower agrees to pay the fees set forth in
this Section 3.3.  All such fees shall be non-refundable.

       SECTION 3.3.1.  Facility Fee.  The Borrower agrees to pay to the Agent
for the account of each Lender for each day during the period (including any
portion thereof when any of the Revolving Loan Commitments are suspended by
reason of the Borrower's inability to satisfy any condition of Article VI)
commencing on  January 14, 1996 and continuing through the Revolving Loan
Commitment Termination Date, a facility fee on the Revolving Loan Commitment
Amount for such day, calculated on the basis of the percentage per annum set
forth opposite the "Level" below containing the Senior Debt Rating of both
Standard & Poor's and Moody's in effect for such day; provided, however, that
in the event of (i) a split rating by Standard & Poor's and Moody's which
differs by one Level, the percentage corresponding to the higher Level (i.e.,
the better Senior Debt Rating) shall be the percentage and (ii) a split rating
by Standard & Poor's and Moody's which differs by more than one Level, the
percentage corresponding to the Level immediately below the higher Level shall
be the percentage; provided further, however, that in the event that (i) only
Standard & Poor's or only Moody's is providing a Senior Debt Rating, the
percentage set forth opposite the Level containing the Senior Debt Rating
which has been provided shall be the percentage or (ii) neither Standard &
Poor's nor Moody's is providing a Senior Debt Rating, the percentage set forth
opposite Level V shall be the percentage.

              Senior Debt Rating         Senior Debt Rating

Such fee shall be payable by the Borrower in arrears on each Quarterly Payment
Date, commencing with the first such Quarterly Payment Date following the
Effective Date and on the Revolving Loan Commitment Termination Date.

       SECTION 3.3.2.  Letter of Credit Face Amount Fee.  The Borrower agrees
to pay to the Agent, for the account of the Lenders, a fee for each Letter of
Credit for the period from and including the date of the issuance of such
Letter of Credit (which date, in the case of an Existing Letter of Credit,
shall be the Closing Date) to (but excluding) the date upon which such Letter
of Credit expires equal to the LIBO Rate Margin then in effect per annum of
the Stated Amount of such Letter of Credit.  Such fee shall be calculated on a
daily basis and shall be payable by the Borrower in arrears on each Quarterly
Payment Date to occur after issuance of such Letter of Credit and on the
Revolving Loan Commitment Termination Date.

       SECTION 3.3.3.  Letter of Credit Issuer Fronting Fee.  The Borrower
agrees to pay to the Agent, for the account of the applicable Issuer, an
issuing fee for each Letter of Credit for the period from and including the
date of issuance of such Letter of Credit (which date, in the case of an
Existing Letter of Credit, shall be the Closing Date) to (but excluding) the
date upon which such Letter of Credit expires equal to the product of the
applicable Fronting Rate multiplied by the Stated Amount of such Letter of
Credit.  Such fee shall be payable by the Borrower in arrears on each
Quarterly Payment Date to occur after issuance of such Letter of Credit and on
the Revolving Loan Commitment Termination Date.

       SECTION 3.3.4.  Letter of Credit Administrative Expenses.  The Borrower
agrees to pay to the Agent, for the account of the applicable Issuer(s), the
amounts referred to in Section 4.3.

       SECTION 3.3.5.  Other Fees.  The Borrower agrees to pay to the Agent
for its account, or to the Agent for the account of the Lenders and/or the
Issuer(s), as the case may be, such fees as previously agreed to in writing by
the applicable parties and not otherwise set forth in this Section 3.3.


                                  ARTICLE IV

                               LETTERS OF CREDIT

       SECTION 4.1.  Issuances and Extensions.  On the terms and subject to
the conditions of this Agreement (including Article VI), the applicable Issuer
or Issuers shall issue Letters of Credit (and extend the Stated Expiry Dates
of outstanding Letters of Credit) in accordance with the Issuance Requests made
therefor pursuant to Section 4.2.  Each Issuer will make available the
original of each Letter of Credit which it issues in accordance with the
Issuance Request therefor to the beneficiary thereof, and will promptly
provide each of the Lenders with a copy of such Letter of Credit (and will
notify the beneficiary under any such Letter of Credit of any extension of the
Stated Expiry Date thereof).  Each Letter of Credit (as defined in the
Existing Credit Facility) outstanding under the Existing Credit Facility on
the Closing Date (each, an "Existing Letter of Credit") shall be deemed to
have been issued hereunder on the Closing Date and, on and as of the Closing
Date, each Issuer of each Existing Letter of Credit hereby releases each
Lender (as defined in the Existing Credit Facility) from all obligations under
the Existing Credit Facility in respect of any Existing Letter of Credit.

       SECTION 4.2.  Issuance Requests.  By delivering to the Agent and the
applicable Issuer an Issuance Request on or before 12:00 noon, New York City
time, the Borrower may request, from time to time prior to the Revolving Loan
Commitment Termination Date and on not less than three nor more than ten
Business Days' notice, that such Issuer issue an irrevocable commercial or
standby letter of credit in such form as may be requested by the Borrower
(each such request to include (i) the forms of instruments to be used to make
draws thereunder and to extend or renew the term thereof and (ii) the written
confirmation of the beneficiary thereunder as to its acceptance of such forms)
and approved in every respect by such Issuer (each such letter of credit,
together with each Existing Letter of Credit, a "Letter of Credit"), for any
purpose permitted under Section 5.11.  Upon receipt of an Issuance Request,
the Agent shall promptly notify the Lenders thereof.  Each Letter of Credit
shall by its terms:

             (a)     be issued in a Stated Amount which

                 (i)  is at least $100,000; and

                 (ii)  does not exceed the then Letter of Credit Availability;

             (b)     be stated to expire on a date (its "Stated Expiry Date")
       no later than the Revolving Loan Commitment Termination Date; and

             (c)     in the case of Letters of Credit other than Judgment
       Letters of Credit and Letters of Credit to be used as credit support
       for corporate insurance purposes, on or prior to its Stated Expiry Date

                 (i)  terminate immediately upon notice to the Issuer thereof
             from the beneficiary thereunder that all obligations covered
             thereby have been terminated, paid, or otherwise satisfied in
             full, and

                 (ii)  reduce in part immediately and to the extent the
             beneficiary thereunder has notified the Issuer thereof that the
             obligations covered thereby have been paid or otherwise satisfied
             in part.

So long as no Default has occurred and is continuing, by delivery to the
applicable Issuer and the Agent of an Issuance Request at least three (or, in
the case of a Judgment Letter of Credit, fifteen) but not more than sixty
Business Days prior to the Stated Expiry Date of any Letter of Credit, the
Borrower may request such Letter of Credit Issuer to extend the Stated Expiry
Date of such Letter of Credit for an additional period that does not end after
the Revolving Loan Commitment Termination Date.  Notwithstanding any provision
contained in the foregoing to the contrary, the Borrower may not request the
issuance of, and no Issuer shall have an obligation to issue, (i) any Judgment
Letter of Credit at any time when, or if after giving effect to such issuance,
and as long as, there shall be outstanding in the aggregate eight Judgment
Letters of Credit or (ii) any Letter of Credit at any time when, or if after
giving effect to such issuance, and so long as, there shall be outstanding in
the aggregate thirty Letters of Credit (including Judgment Letters of Credit).

       SECTION 4.3.  Expenses.  The Borrower agrees to pay to the Agent for
the account of the applicable Issuer(s) all standard administrative expenses
of such Issuer(s) in connection with the issuance, maintenance, modification
(if any) and administration of each Letter of Credit issued by such Issuer(s)
upon demand from time to time.

       SECTION 4.4.  Participation By Lenders.  (a)  Each Letter of Credit
issued or deemed issued pursuant to this Article IV  shall, effective upon its
issuance or deemed issuance and without further action, be issued or deemed
issued on behalf of all Lenders (including the applicable Issuer) pro rata
according to their respective Percentages.  Each Lender shall, to the extent
of its Percentage, be deemed irrevocably to have participated in the issuance
of such Letter of Credit and shall be responsible to reimburse promptly the
applicable Issuer for Reimbursement Obligations which have not been reimbursed
by the Borrower in accordance with Section 4.5, or which have been reimbursed
by the Borrower but must be returned, restored or disgorged by such Issuer for
any reason.  Each Lender shall, to the extent of its Percentage, be entitled
to receive from the Agent a ratable portion of the letter of credit fees
received by the Agent pursuant to Section 3.3.2, with respect to each Letter
of Credit.

       (b)   In the event that the Borrower shall fail to reimburse any
Issuer, or if for any reason Revolving Loans shall not be made to fund any
Reimbursement Obligation, all as provided in Section 4.5 and in an amount
equal to the amount of any drawing honored by such Issuer under a Letter of
Credit issued by it, or in the event such Issuer must for any reason return or
disgorge such reimbursement, such Issuer shall promptly notify each Lender of
the unreimbursed amount of such drawing and of such Lender's respective
participation therein.  Each Lender shall make available to such Issuer,
whether or not any Default shall have occurred and be continuing, an amount
equal to its respective participation in same day or immediately available
funds at the office of such Issuer specified in such notice not later than
11:00 a.m., New York City time, on the Business Day (under the laws of the
jurisdiction of such Issuer) after the date notified by such Issuer.  In the
event that any Lender fails to make available to such Issuer the amount of
such Lender's participation in such Letter of Credit as provided herein, such
Issuer shall be entitled to recover such amount on demand from such Lender
together with interest at the daily average Federal Funds Effective Rate for
three Business Days (together with such other compensatory amounts as may be
required to be paid by such Lender to the Agent pursuant to the Rules for
Interbank Compensation of the council on International Banking or the
Clearinghouse Compensation Committee, as the case may be, as in effect from
time to time) and thereafter at the Federal Funds Effective Rate plus 2.0%.

       (c)   Nothing in this Section shall be deemed to prejudice the right of
any Lender to recover from any Issuer any amounts made available by such
Lender to such Issuer pursuant to this Section in the event that it is
determined by a court of competent jurisdiction that the payment with respect
to a Letter of Credit by such Issuer in respect of which payment was made by
such Lender constituted gross negligence or wilful misconduct on the part of
such Issuer.

       (d)   Each Issuer shall distribute to each other Lender which has paid
all amounts payable by it under this Section with respect to any Letter of
Credit issued by such Issuer such other Lender's Percentage of all payments
received by such Issuer from the Borrower in reimbursement of drawings honored
by such Issuer under such Letter of Credit when such payments are received.

       SECTION 4.5.  Disbursements.  (a)  The applicable Issuer will notify
the Borrower and the Agent promptly of the presentment for payment of any
drawing under any Letter of Credit, together with notice of the amount of such
drawing and the date (a "Disbursement Date") such payment shall be made.

       (b)   Subject to the terms and provisions of such Letter of Credit, the
applicable Issuer shall make such payment to the beneficiary (or its designee)
of such Letter of Credit.

       (c)   Prior to 12:00 noon, New York City time, on the Business Day
immediately succeeding the Disbursement Date, the Borrower will reimburse the
applicable Issuer for all amounts which it has disbursed under such Letter of
Credit.

       (d)   To the extent the applicable Issuer is not reimbursed in full on
the Disbursement Date for all amounts it has disbursed under any Letter of
Credit, the Borrower's Reimbursement Obligation shall accrue interest from and
including such Disbursement Date to but excluding the date such Reimbursement
Obligation is paid in full (whether pursuant to a Borrowing of Base Rate Loans
under Section 4.5(e) or otherwise) at a fluctuating rate per annum equal to,
during the initial two days after such Disbursement Date, the Alternate Base
Rate and, thereafter, the Alternate Base Rate plus a margin of 2.0%, payable
on demand.

       (e)   In the event the applicable Issuer is not reimbursed by the
Borrower on the Disbursement Date, or if such Issuer must for any reason
return or disgorge such reimbursement, the Lenders (including such Issuer)
shall, on the terms and subject to the conditions of this Agreement, fund the
Reimbursement Obligation therefor by making, on the next Business Day,
Revolving Loans which are Base Rate Loans as provided in Section 2.1.1 (the
Borrower being deemed to have given a timely Borrowing Request therefor for
such amount); provided, however, for the purpose of determining the
availability of the Revolving Loan Commitments to make Revolving Loans
immediately prior to giving effect to the application of the proceeds of such
Revolving Loans, such Reimbursement Obligation shall be deemed not to be
outstanding at such time.

       SECTION 4.6.  Repayment/Reimbursement.  The Borrower's obligation (a
"Reimbursement Obligation") under Section 4.5 to reimburse an Issuer with
respect to each disbursement thereunder (including interest thereon), and each
Lender's obligation to make participation payments in each drawing which has
not been reimbursed by the Borrower, shall be absolute and unconditional under
any and all circumstances and irrespective of any setoff, counterclaim, or
defense to payment which the Borrower may have or have had against any Lender
or any beneficiary of a Letter of Credit, including any defense based upon the
occurrence of any Default, any draft, demand or certificate or other document
presented under a Letter of Credit proving to be forged, fraudulent, invalid
or insufficient, the failure of any disbursement thereunder to conform to the
terms of the applicable Letter of Credit (if, in the applicable Issuer's good
faith opinion, such disbursement is determined to be appropriate) or any
non-application or misapplication by the beneficiary of the proceeds of such
disbursement, or the legality, validity, form, regularity, or enforceability
of such Letter of Credit.

       SECTION 4.7.  Deemed Disbursements and Cash Collateralization of
Letters of Credit.  Upon the occurrence and during the continuation of any
Event of Default or the occurrence of the Revolving Loan Commitment
Termination Date, an amount equal to that portion of Letter of Credit
Outstandings attributable to outstanding and undrawn Letters of Credit shall,
at the election of the applicable Issuer acting on instructions from the
Required Lenders, and without demand upon or notice to the Borrower, be deemed
to have been paid or disbursed (but not for purposes of Sections 3.3 and 4.5)
by such Issuer under such Letters of Credit (notwithstanding that such amount
may not in fact have been so paid or disbursed), and, upon notification by
such Issuer to the Agent and the Borrower of its obligations under this
Section (which notification shall be deemed given if the applicable Event of
Default is an Event of Default with respect to the Borrower or ADT Limited
described in clause (b) or (d) of Section 9.1.9), the Borrower shall be
immediately obligated to reimburse such Issuer the amount deemed to have been
so paid or disbursed by such Issuer.  Any amounts so received by such Issuer
from the Borrower pursuant to this Section shall be held as collateral
security for the repayment of the Borrower's obligations in connection with
the Letters of Credit issued by such Issuer.  At any time when the aggregate
amount held by any Issuer as collateral hereunder shall exceed the then
aggregate Letter of Credit Outstandings in respect of all Letters of Credit
issued by such Issuer, such Issuer shall return to the Borrower such excess.
At such time when all Events of Default shall have been cured or waived, each
Issuer shall return to the Borrower all amounts then on deposit with such
Issuer pursuant to this Section.  Any interest on such amounts on deposit
shall be held by the applicable Issuer as additional collateral security for
the repayment of the Borrower's Obligations in connection with the Letters of
Credit issued by such Issuer or otherwise.

       SECTION 4.8.  Nature of Repayment/Reimbursement Obligations.  With
respect to all Letters of Credit, the Borrower shall assume all risks of
the acts, omissions, or misuse of any Letter of Credit by the beneficiary
thereof.  Neither any Issuer nor any Lender (except to the extent of its
own gross negligence or wilful misconduct) shall be responsible for:

             (a)     the form, validity, sufficiency, accuracy, genuineness,
       or legal effect of any Letter of Credit or any document submitted by
       any party in connection with the application for and issuance of a
       Letter of Credit, even if it should in fact prove to be in any or all
       respects invalid, insufficient, inaccurate, fraudulent, or forged;

             (b)     the form, validity, sufficiency, accuracy, genuineness,
       or legal effect of any instrument transferring or assigning or
       purporting to transfer or assign a Letter of Credit or the rights or
       benefits thereunder or proceeds thereof in whole or in part, which may
       prove to be invalid or ineffective for any reason;

             (c)     failure of the beneficiary to comply fully with
       conditions required in order to demand payment under a Letter of Credit;

             (d)     errors, omissions, interruptions, or delays in
       transmission or delivery of any messages, by mail, cable, telegraph,
       telex, or otherwise; or

             (e)     any loss or delay in the transmission or otherwise of any
       document or draft required in order to make a Disbursement under a
       Letter of Credit or of the proceeds thereof.

None of the foregoing shall affect, impair, or prevent the vesting of any of
the rights or powers granted any Issuer or any Lender hereunder.  In
furtherance and extension, and not in limitation or derogation, of any of the
foregoing, any action taken or omitted to be taken by any Issuer in good faith
shall be binding upon the Borrower and shall not put such Issuer under any
resulting liability to the Borrower.

       SECTION 4.9.  Increased Costs; Indemnity.  With respect to all Letters
of Credit, if by reason of

             (a)     any change after the date hereof in applicable law,
       regulation, rule, decree or regulatory requirement or any change in the
       interpretation or application by any judicial or regulatory authority
       of any law, regulation, rule, decree or regulatory requirement, or

             (b)     compliance by any Issuer or any Lender with any
       direction, request or requirement (whether or not having the force of
       law) of any governmental or monetary authority, including Regulation D
       of the F.R.S. Board, first issued after the date hereof:

                 (i)  any Issuer or any Lender shall be subject to any tax
             (other than taxes on net income and franchises), levy, charge or
             withholding of any nature or to any variation thereof or to any
             penalty with respect to the maintenance or fulfillment of its
             obligations under this Article IV, whether directly or by such
             being imposed on or suffered by such Issuer or any Lender;

                 (ii)  any reserve, deposit or similar requirement is or shall
             be applicable, imposed or modified in respect of any Letters of
             Credit issued by any Issuer or participations therein purchased
             by any Lender; or

                 (iii)  there shall be imposed on any Issuer or any Lender any
             other condition regarding this Article IV, any Letter of Credit
             or any participation therein;

and the result of the foregoing is directly or indirectly to increase the
actual cost to such Issuer or such Lender of issuing, making or maintaining
any Letter of Credit or of purchasing or maintaining any participation
therein, or to actually reduce any amount receivable in respect thereof by such
Issuer or such Lender, then and in any such case such Issuer or such Lender
may, at any time after the additional cost is incurred or the amount received
is reduced, notify the Borrower thereof, and the Borrower shall pay within
fourteen days of demand thereof such amounts as such Issuer or Lender may
specify to be necessary to compensate such Issuer or Lender for such
additional cost or reduced receipt, together with interest on such amount from
the date demanded until payment in full thereof at a rate equal, during the
initial fifteen Business Days after the date of such demand, the Alternate
Base Rate, and, thereafter, the Alternate Base Rate plus a margin of 2.0%;
provided, however, that the Borrower shall have no obligation to pay any such
additional amount with respect to any day or days unless such Issuer or Lender
shall have notified the Borrower of its demand therefor within 60 days of the
date upon which such Issuer or Lender has obtained audited information with
respect to the fiscal year of such Issuer or Lender in which such day or days
occurred; provided further, however, that each such Issuer or Lender will use
all reasonable efforts to obtain such audited information in a timely manner.
The determination by such Issuer or Lender, as the case may be, of any amount
due pursuant to this Section, as set forth in a statement setting forth the
calculation thereof in reasonable detail, shall, in the absence of manifest
error, be final and conclusive and binding on all of the parties hereto.  In
addition to amounts payable as elsewhere provided in this Article IV, the
Borrower hereby agrees to protect, indemnify, pay and save each Issuer
harmless from and against any and all claims, demands, liabilities, damages,
losses, costs, charges and expenses (including reasonable attorneys' fees and
allocated costs of internal counsel) which such Issuer may incur or be subject
to as a consequence, direct or indirect, of

             (x)  the issuance of the Letters of Credit, other than as a
       result of the gross negligence or wilful misconduct of such Issuer as
       determined by a court of competent jurisdiction, or

             (y)  the failure of such Issuer to honor a drawing under any
       Letter of Credit as a result of any act or omission, whether rightful
       or wrongful, of any present or future de jure or de facto government or
       governmental authority.


                                   ARTICLE V

                    CERTAIN LIBO RATE AND OTHER PROVISIONS

       SECTION 5.1.  LIBO Rate Lending Unlawful.  If any Lender shall
determine (which determination shall, upon notice thereof to the Borrower and
the Lenders, be conclusive and binding on the Borrower) that the introduction
of, or any change in or in the interpretation of, any law makes it unlawful,
or any central bank or other governmental authority asserts that it is
unlawful, for such Lender to make, continue or maintain any Loan as, or to
convert any Loan into, a LIBO Rate Loan, the obligations of such Lender to
make, continue or maintain any Loan as, or to convert any Loan into, a LIBO
Rate Loan shall, upon such determination, forthwith be suspended until such
Lender shall notify the Agent that the circumstances causing such suspension
no longer exist, and all LIBO Rate Loans of such Lender shall automatically
convert into Base Rate Loans at the end of the then current Interest Periods
with respect thereto or sooner, if required by such law or assertion and all
Loans of such Lender that would otherwise have been made or continued as, or
converted into, LIBO Rate Loans shall instead be made as or converted into, or
continued as, Base Rate Loans upon which interest shall be payable (i) in the
case of Revolving Loans, at the same time as the related LIBO Rate Loans and
(ii) in the case of Competitive Bid Loans, on the Competitive Bid Loan
Interest Payment Date with respect thereto.

       SECTION 5.2.  Deposits Unavailable.  If the Agent shall have determined
that

             (a)     Dollar deposits in the relevant amount and for the
       relevant Interest Period are not available to the Reference Lender or
       the Reference Lenders, as the case may be, in their relevant market; or

             (b)     by reason of circumstances affecting the Reference
       Lenders' relevant market, adequate means do not exist for ascertaining
       the interest rate applicable hereunder to LIBO Rate Loans,

then, upon notice from the Agent to the Borrower and the Lenders, the
obligations of all Lenders under Section 2.2 and Section 2.4 to make or
continue any Revolving Loans as, or to convert any Revolving Loans into, LIBO
Rate Loans shall forthwith be suspended until the Agent shall notify the
Borrower and the Lenders that the circumstances causing such suspension no
longer exist.

       SECTION 5.3.  Increased LIBO Rate Loan Costs, etc.  The Borrower agrees
to reimburse each Lender for any increase in the actual cost to such Lender
of, or any actual reduction in the amount of any sum receivable by such Lender
in respect of, making, continuing or maintaining (or of its obligation to make,
continue or maintain) any Loans as, or of converting (or of its obligation to
convert) any Loans into, LIBO Rate Loans arising by reason of (i) any change
(after the date hereof, in respect of LIBO Rate Loans that are Revolving
Loans, or after the date of the applicable Competitive Bid Loan Offer, in
respect of Competitive Bid Loans) in any applicable law, rule, regulation,
decree or regulatory requirement or any change (after such date) in the
interpretation or application by any judicial or regulatory authority of any
applicable law, rule, regulation, decree or regulatory requirement or (ii)
compliance by such Lender with any direction, request or requirement (whether
or not having the force of law) of any governmental or monetary authority,
including Regulation D of the F.R.S. Board, first issued after such date;
provided, however, that the Borrower shall have no obligation to pay any such
additional amount with respect to any day or days unless such Lender shall
have notified the Borrower of its demand therefor within 60 days of the date
upon which such Lender has obtained audited information with respect to the
fiscal year of such Lender in which such day or days occurred; provided
further, however, that each such Lender will use all reasonable efforts to
obtain such audited information in a timely manner.  Such Lender shall promptly
notify the Agent and the Borrower in writing of the occurrence of any such
event, such notice to state, in reasonable detail, the reasons therefor and
the additional amount required fully to compensate such Lender for such
increased cost or reduced amount.  Such additional amounts shall be payable by
the Borrower directly to such Lender within fourteen days of its receipt of
such notice, and such notice shall, in the absence of manifest error, be
conclusive and binding on the Borrower.

       SECTION 5.4.  Funding Losses.  In the event any Lender shall incur any
loss or expense (including any loss or expense incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by such Lender
to make, continue or maintain any portion of the principal amount of any Loan
as, or to convert any portion of the principal amount of any Loan into, a LIBO
Rate Loan) as a result of

             (a)     any conversion or repayment or prepayment of the
       principal amount of any LIBO Rate Loans on a date other than the
       scheduled last day of the Interest Period applicable thereto, whether
       pursuant to Section 3.1 or otherwise;

             (b)     any Loans not being made as LIBO Rate Loans in accordance
       with the Borrowing Request therefor; or

             (c)     any Revolving Loans not being continued as, or converted
       into, LIBO Rate Loans in accordance with the Continuation/Conversion
       Notice therefor,

but excluding loss of margin for the period after such payment, conversion or
failure to borrow, then, upon the written notice of such Lender to the
Borrower (with a copy to the Agent), the Borrower shall, within fourteen days
of its receipt thereof, pay directly to such Lender such amount as will (in
the reasonable determination of such Lender) reimburse such Lender for such
loss or expense.  Such written notice (which shall include calculations in
reasonable detail) shall, in the absence of manifest error, be conclusive and
binding on the Borrower.

       SECTION 5.5.  Increased Capital Costs.  If after the date hereof (or,
with respect to any Competitive Bid Loan, the date of the Competitive Bid Loan
Offer with respect thereto), there shall be any change in, or the
introduction, adoption, effectiveness, interpretation, reinterpretation or
phase-in of, any law or regulation, directive, guideline, decision or request
(whether or not having the force of law) of any court, central bank, regulator
or other governmental authority affects or would affect the amount of capital
required or expected to be maintained by any Lender or any Person controlling
such Lender, and such Lender determines (in its sole and absolute discretion)
that the rate of return on its or such controlling Person's capital as a
consequence of its Revolving Loan Commitment, issuance of or participation in
Letters of Credit or the Loans made by such Lender is reduced to a level below
that which such Lender or such controlling Person could have achieved but for
the occurrence of any such circumstance, then, in any such case upon notice
from time to time by such Lender to the Borrower, the Borrower shall, within
fourteen days of its receipt of such notice from such Lender, pay directly to
such Lender additional amounts sufficient to compensate such Lender or such
controlling Person for such reduction in rate of return; provided, however,
that the Borrower shall have no obligation to pay any such additional amount
with respect to any day or days unless such Lender shall have notified the
Borrower of its demand therefor within 60 days of the date upon which such
Lender has obtained audited information with respect to the fiscal year of
such Lender in which such day or days occurred; provided further, however,
that each such Lender will use all reasonable efforts to obtain such audited
information in a timely manner.  A statement of such Lender as to any such
additional amount or amounts (including calculations thereof in reasonable
detail) shall, in the absence of manifest error, be conclusive and binding on
the Borrower.  In determining such amount, such Lender may use any reasonable
method of averaging and attribution that it shall deem applicable.

       SECTION 5.6.  Taxes.  All payments by the Borrower of principal of, and
interest on, the Loans and all other amounts payable hereunder shall be made
free and clear of and without deduction for any present or future income,
excise, stamp or franchise taxes, and other taxes, fees, duties, withholdings
and all liabilities related thereto, imposed by any taxing authority and
arising as a result of any change after the date hereof (or, in the case of
any Competitive Bid Loan, after the date of the Competitive Bid Loan Offer
with respect thereto) in any law, regulation or treaty or the interpretation
or application thereof by any relevant taxing authority, but excluding
franchise taxes and taxes imposed on or measured by any Lender's net income or
receipts (such non-excluded items being called "Taxes").  In the event that
any withholding or deduction from any payment to be made by the Borrower
hereunder is required in respect of any Taxes pursuant to any applicable law,
rule or regulation, then the Borrower will

             (a)     pay directly to the relevant authority the full amount
       required to be so withheld or deducted;

             (b)     promptly forward to the Agent an official receipt or
       other documentation satisfactory to the Agent evidencing such payment
       to such authority; and

             (c)     pay to the Agent for the account of the Lenders such
       additional amount or amounts as is necessary to ensure that the net
       amount actually received by each Lender will equal the full amount such
       Lender would have received had no such withholding or deduction been
       required.

Moreover, if any Taxes are directly asserted against the Agent or any Lender
with respect to any payment received by the Agent or such Lender hereunder,
the Agent or such Lender may pay such Taxes and the Borrower will promptly pay
such additional amounts (including any penalties, interest or expenses) as is
necessary in order that the net amount received by such person after the
payment of such Taxes (including any Taxes on such additional amount) shall
equal the amount such person would have received had not such Taxes been
asserted; provided, however, that the Borrower shall have no obligation to pay
any such additional amount unless such Lender shall have notified the Borrower
of its demand therefor within 60 days of the date upon which such Lender has
obtained audited information with respect to the fiscal year of such Lender
during which the payment of such additional amounts occurred; provided
further, however, that each such Lender will use all reasonable efforts to
obtain such audited information in a timely manner.

       If the Borrower fails to pay any Taxes when due to the appropriate
taxing authority or fails to remit to the Agent, for the account of the
respective Lenders, the required receipts or other required documentary
evidence, the Borrower shall indemnify the Lenders for any incremental Taxes,
interest or penalties that may become payable by any Lender as a result of any
such failure.  For purposes of this Section 5.6, a distribution hereunder by
the Agent or any Lender to or for the account of any Lender shall be deemed a
payment by the Borrower.

       Each Lender that is organized under the laws of a jurisdiction other
than the United States (or any state thereof or the District of Columbia)
shall provide its portion of the Revolving Loan Commitment through a branch or
office the income of which that relates hereto is effectively connected with
the conduct of a trade or business in the United States.  On or prior to the
Effective Date (in the case of any Lender party hereto on the Effective Date
or the Agent) or the date upon which such Lender or Agent becomes a Lender or
Agent hereunder (in the case of any other Lender or Agent) and from time to
time thereafter as the Borrower may reasonably request (which request shall
not be made more than once per Fiscal Year), each Lender and Agent that is
organized under the laws of a jurisdiction other than the United States (or
any state thereof or the District of Columbia) shall execute and deliver to
the Borrower and the Agent one or more (as the Borrower or the Agent may
reasonably request) United States Internal Revenue Service Forms 4224 or such
other forms or documents (or successor forms or documents), appropriately
completed, as may be applicable to establish the extent, if any, to which a
payment to such Lender or Agent is exempt from withholding or deduction of
Taxes.  If the form provided by any Lender or the Agent at the time such
Lender or the Agent first becomes a party to this Agreement indicates a
withholding or deduction of taxes at a rate in excess of zero, withholding or
deduction of taxes at such rate shall be excluded from "Taxes" as defined in
this Section 5.6; provided, however, that any increase in such rate shall not
be so excluded from "Taxes".  For any period with respect to which a Lender
has failed to provide the Borrower with the appropriate form pursuant to this
Section 5.6, such Lender shall not be entitled to receive any additional
amount pursuant to this Section 5.6.

       SECTION 5.7.  Payments, Computations, etc.  Unless otherwise expressly
provided, all payments by the Borrower pursuant to this Agreement, the Notes
or any other Loan Document shall be made by the Borrower to the Agent for the
pro rata account of the Lenders entitled to receive such payment.  All such
payments required to be made to the Agent shall be made, without setoff,
deduction or counterclaim, not later than 12:00 noon, New York City time, on
the date due, in same day or immediately available funds, to such account as
the Agent shall specify from time to time by notice to the Borrower.  Funds
received after that time shall be deemed to have been received by the Agent on
the next succeeding Business Day.  The Agent shall promptly remit in same day
funds to each Lender its share, if any, of such payments received by the Agent
for the account of such Lender.  All interest and fees shall be computed on the
basis of the actual number of days (including the first day but excluding the
last day) occurring during the period for which such interest or fee is
payable over a year comprised of 360 days (or, in the case of interest on a
Base Rate Loan (other than when calculated with respect to the Federal Funds
Effective Rate), 365 days or, if appropriate, 366 days).  Whenever any payment
to be made shall otherwise be due on a day which is not a Business Day, such
payment shall (except as otherwise required by clause (b) of the definition of
the term "Interest Period" with respect to LIBO Rate Loans) be made on the
next succeeding Business Day and such extension of time shall be included in
computing interest and fees, if any, in connection with such payment.

       SECTION 5.8.  Sharing of Payments.  If any Lender shall obtain any
payment or other recovery (whether voluntary, involuntary, by application of
setoff or otherwise) on account of any Revolving Loan (other than pursuant to
the terms of Sections 5.3, 5.4 and 5.5) or any Letter of Credit in excess of
its pro rata share of payments then or therewith obtained by all Lenders, such
Lender shall purchase from the other Lenders such participations in Revolving
Loans made by them and/or Letters of Credit as shall be necessary to cause
such purchasing Lender to share the excess payment or other recovery ratably
with each of them; provided, however, that if all or any portion of the excess
payment or other recovery is thereafter recovered from such purchasing Lender,
the purchase shall be rescinded and each Lender which has sold a participation
to the purchasing Lender shall repay to the purchasing Lender the purchase
price to the ratable extent of such recovery together with an amount equal to
such selling Lender's ratable share (according to the proportion of

             (a)     the amount of such selling Lender's required repayment to
       the purchasing Lender

to

             (b)     the total amount so recovered from the purchasing Lender)

of any interest or other amount paid or payable by the purchasing Lender in
respect of the total amount so recovered.  The Borrower agrees that any Lender
so purchasing a participation from another Lender pursuant to this Section
may, to the fullest extent permitted by law, exercise all its rights of
payment (including pursuant to Section 5.9) with respect to such participation
as fully as if such Lender were the direct creditor of the Borrower in the
amount of such participation.  If under any applicable bankruptcy, insolvency
or other similar law, any Lender receives a secured claim in lieu of a setoff
to which this Section applies, such Lender shall, to the extent practicable,
exercise its rights in respect of such secured claim in a manner consistent
with the rights of the Lenders entitled under this Section to share in the
benefits of any recovery on such secured claim.

       SECTION 5.9.  Setoff.  Each Lender shall, upon the occurrence of any
Event of Default, to the fullest extent permitted under applicable law, have
the right to appropriate and apply to the payment of the Obligations owing to
it (whether or not then due) any and all balances, credits, deposits, accounts
or moneys of the Borrower then or thereafter maintained with or otherwise held
by such Lender; provided, however, that any such appropriation and application
shall be subject to the provisions of Section 5.8.  Each Lender agrees
promptly to notify the Borrower and the Agent after any such setoff and
application made by such Lender; provided, however, that, to the fullest extent
permitted under applicable law, the failure to give such notice shall not
affect the validity of such setoff and application.  The rights of each Lender
under this Section are in addition to other rights and remedies (including
other rights of setoff under applicable law or otherwise) which such Lender
may have.

       SECTION 5.10.  Use of Proceeds.  The proceeds of any Loans shall be
used for general corporate purposes, including to provide working capital and
to finance acquisitions permitted hereunder in Core Businesses.  Without
limiting the foregoing, no proceeds of any Loan shall be used to acquire any
equity security of a class which is registered pursuant to Section 12 of the
Exchange Act or any "margin stock", as defined in F.R.S. Board Regulation U.

       SECTION 5.11.  Use of Letters of Credit.  Letters of Credit shall be
used for general corporate purposes, including:

             (a)  as credit support for corporate insurance purposes;

             (b)  as credit support for working capital facilities provided to
       Affiliates of the Borrower;

             (c)  in support of trade obligations; and

             (d)  in the case of Judgment Letters of Credit, in support of
       obligations to Judgment Payors (as defined in the definition of
       "Judgment Letters of Credit").

       SECTION 5.12.  Substitution of LIBOR Office or Domestic Office in
Certain Circumstances.  If any Lender would otherwise (a) have its obligation
to make, continue or maintain Loans as, or convert Loans into, LIBO Rate Loans
suspended pursuant to Section 5.1 or (b) be entitled to receive additional
amounts pursuant to Section 5.3, 5.5 or 5.6, such Lender shall designate a
different Domestic Office or LIBOR Office, as the case may be, if such
designation will avoid the need for such suspension or eliminate or reduce the
amounts of such additional amounts and will not, in the sole judgement of such
Lender, be otherwise disadvantageous to such Lender.

       SECTION 5.13.  Substitution of Bank; Election to Terminate.  If (a) the
obligation of any Lender to make, continue or maintain Loans as, or to convert
Revolving Loans into, LIBO Rate Loans has been suspended pursuant to Section
5.1 or (b) any Lender has demanded to be paid additional amounts pursuant to
Section 5.3, 5.5 or 5.6 (and the Borrower, in its reasonable judgment,
believes such Lender is likely to demand additional amounts thereunder), the
Borrower shall have the right, with the assistance of the Agent, to seek one
or more financial institutions (a "Substitute Lender"), which may be one or
more of the Lenders, to purchase the Notes and assume the Revolving Loan
Commitment of such Lender (the "Affected Lender"), and if the Borrower locates
a Substitute Lender, the Affected Lender shall, upon (i) payment to it of the
purchase price agreed between it and the Substitute Lender (or, failing such
agreement, a purchase price in the amount of the outstanding principal amount
of its Loans and accrued interest thereon to the date of payment) plus any
amount (other than principal and interest) then due to it or accrued for its
account hereunder, (ii) the written consent of each Issuer (which consent
shall be based on such Issuer's reasonable determination of the ability of
such Substitute Lender to meet the financial obligations of a Lender
hereunder) and (iii) payment by the Borrower to the Affected Lender and the
Agent of all reasonable out-of-pocket expenses in connection with such
assignment and assumption, assign all its rights and obligations under this
Agreement and the Notes (including its Revolving Loan Commitment and its
Loans) to the Substitute Lender, and the Substitute Lender shall assume such
rights and obligations, whereupon the Substitute Lender shall become a party
hereto and shall have the rights and obligations of a Lender hereunder and
under the other Loan Documents and the Affected Lender shall be released from
its obligations hereunder and under the other Loan Documents.

renewal of any Letter of Credit, as applicable, shall constitute a
representation and warranty by the Borrower that on the date of such Borrowing
(both immediately before and after giving effect to such Borrowing and the
application of the proceeds thereof) or the issuance, extension or renewal of
such Letter of Credit, as applicable, the statements made in clauses (a), (b)

                                  ARTICLE VII

                        REPRESENTATIONS AND WARRANTIES

       In order to induce the Lenders and the Agent to enter into this
Agreement and to make Loans and issue Letters of Credit hereunder, the
Borrower represents and warrants unto the Agent and each Lender as set forth
in this Article VII.

       SECTION 7.1.  Organization, etc.  Each of the Borrower and its
Subsidiaries that is an Obligor is a corporation duly organized and validly
existing and in good standing under the laws of the State of its
incorporation, is duly qualified to do business and is in good standing as a
foreign corporation in each jurisdiction where the nature of its business or
the location of its assets requires such qualification and where the failure to
so qualify or be in good standing would reasonably be expected to have a
material adverse effect on the business, results of operations, financial
condition or prospects of the Borrower and its Subsidiaries taken as a whole.
Each of the Borrower and its Subsidiaries that is an Obligor has full power
and authority and holds all requisite governmental licenses, permits and other
approvals (i) to own and hold under lease its property and to conduct its
business substantially as currently conducted by it, except where failure to
hold such licenses, permits and other approvals would not reasonably be
expected to have a material adverse effect on the business, results of
operations, financial condition or prospects of the Borrower and its
Subsidiaries taken as a whole and (ii) to enter into and perform its
Obligations under each Loan Document to which it is a party.

       SECTION 7.2.  Due Authorization, Non-Contravention, etc.  The
execution, delivery and performance by the Borrower of this Agreement, the
Notes and each other Loan Document executed or to be executed by it, and the
execution, delivery and performance by each Subsidiary of the Borrower that is
an Obligor of each Loan Document executed or to be executed by it are within
the Borrower's and each such Obligor's corporate powers, have been duly
authorized by all necessary corporate action, and do not

             (a)     contravene the Borrower's or any such Obligor's Organic
       Documents;

             (b)     contravene any contractual restriction, law or
       governmental regulation or court decree or order binding on or
       affecting the Borrower or any such Obligor in any manner that could
       reasonably be expected (i) to have a material adverse effect on the
       business, results of operations, financial condition or prospects of
       the Borrower and its Subsidiaries taken as a whole or (ii) to subject
       any Lender, Issuer or Agent to any liability; or

             (c)     result in, or require the creation or imposition of, any
       Lien on any of any Obligor's properties.

       SECTION 7.3.  Government Approval, Regulation, etc.  No authorization
or approval or other action by, and no notice to or filing with, any
governmental authority or regulatory body or other Person is required for the
due execution, delivery or performance by the Borrower or any Subsidiary of
the Borrower that is an Obligor of this Agreement, the Notes or any other Loan
Document to which it is a party.  Neither the Borrower nor any of its
Subsidiaries that is an Obligor is an "investment company" within the meaning
of the Investment Company Act of 1940, as amended, or a "holding company", or
a "subsidiary company" of a "holding company", or an "affiliate" of a "holding
company" or of a "subsidiary company" of a "holding company", within the
meaning of the Public Utility Holding Company Act of 1935, as amended.

       SECTION 7.4.  Validity, etc.  This Agreement, the Notes and each other
Loan Document executed by the Borrower constitute the legal, valid and binding
obligations of the Borrower enforceable in accordance with their respective
terms, subject to applicable bankruptcy, insolvency, reorganization,
moratorium or similar laws from time to time in effect affecting creditors'
rights generally and to general principles of equity.

       SECTION 7.5.  No Material Adverse Change.  Since December 31, 1995,
there has been no material adverse change in the business, results of
operations, financial condition or prospects of the Borrower and its
Subsidiaries taken as a whole.

       SECTION 7.6.  Litigation, Labor Controversies, etc.  There is no
pending or, to the knowledge of the Borrower, threatened litigation, action,
proceeding, or labor controversy affecting the Borrower or any of its
Subsidiaries, or any of their respective properties, businesses, assets or
revenues, which could reasonably be expected to materially adversely affect the
financial condition, results of operations, business or prospects of the
Borrower and its Subsidiaries, taken as a whole, or which purports to affect
the legality, validity or enforceability of this Agreement, the Notes or any
other Loan Document, except as disclosed in Item 7.6 ("Litigation") of the
Disclosure Schedule.

       SECTION 7.7.  Subsidiaries.  The Borrower has no Subsidiaries, except
those Subsidiaries

             (a)     which are identified in Item 7.7 ("Existing

(without limitation):

             (a)     except to the extent permitted under Section 4.2.9 of the
       ADT Limited Guaranty, the maintenance and preservation by the Borrower
       and each of its Subsidiaries that is an Obligor of its corporate
       existence and qualification as a foreign corporation in each
       jurisdiction where the nature of its business or the location of its
       assets requires it to be so qualified, except to the extent the failure
       to maintain and preserve its corporate existence or to be so qualified
       could not reasonably be expected to have a material adverse effect on
       the business, results of operations, financial condition or prospects of
       the Borrower and its Subsidiaries, taken as a whole (it being
       acknowledged that the failure of the Borrower to maintain and preserve
       its corporate existence (except as permitted under Section 4.2.9 of the
       ADT Limited Guaranty) shall be deemed to have such a material adverse
       effect); and

             (b)     the payment, before the same become delinquent, of all
       material taxes, assessments and governmental charges imposed upon it or
       upon its property except to the extent being diligently contested in
       good faith by appropriate proceedings and for which adequate reserves
       in accordance with GAAP shall have been set aside on its books.

       SECTION 8.1.3.  Covenants Relating to Judgment Letters of Credit.  (a)
The Borrower agrees that, in the case of each draw under a Judgment Letter of
Credit (each such draw, a "Draw Event"), it will provide to the Agent a
certificate executed by its chief financial Authorized Officer (each such
certificate, a "Draw Certificate") pursuant to which it will show in reasonable
detail:

             (i) to the extent it shall have received such information from
       the Issuer, the amount of such draw (such amount, the "Current Draw
       Amount"),

             (ii) to the extent it shall have previously received such
       information from the Issuer, the aggregate amount of all previous draws
       under all Judgment Letters of Credit (such aggregate amount, the "Prior
       Draw Amount"),

             (iii) the aggregate amount (without duplication) of all cash
       contributions made to the capital of the Borrower by the Borrower's
       parent and of all cash proceeds of Subordinated Intercompany Debt
       provided by ADT Limited or Wholly Owned Subsidiaries of ADT Limited
       (other than Subsidiaries of the Borrower) and permitted pursuant to
       clause (m) of Section 8.2.2, in each case since December 6, 1995 (such
       aggregate amount, the "Investment Amount"), and

             (iv) the aggregate amount (without duplication) counted (A) as an
       Investment under clause (c) of Section 4.2.5 of the ADT Limited
       Guaranty (by virtue of clause (k) of Section 4.2.2 of the ADT Limited
       Guaranty) (the maximum amount permitted under such clause (c) by virtue
       of such clause (k) at any time, the "Borrower Intercompany Debt
       Basket"), (B) as an Investment under clause (o) of Section 4.2.5 of the
       ADT Limited Guaranty (the maximum amount permitted under such clause
       (o) at any time, the "General Debt Basket") or (C) as a Restricted
       Borrower Distribution under clause (b)(ii) of Section 4.2.6 of the ADT
       Limited Guaranty (the maximum amount permitted under such clause
       (b)(ii) at any time, the "Restricted Borrower Distribution Basket"), in
       each case prior to such Draw Event as a result of the immediately
       succeeding sentence (such aggregate amount, the "Basket Usage Amount").

The failure of the Borrower to deliver to the Agents a Draw Certificate within
ten Business Days after notice of a Draw Event shall have been given to the
Borrower shall constitute an Event of Default.

       (b)  The Borrower acknowledges that, upon each Draw Event, the excess,
if any, of (i) the sum of the Current Draw Amount with respect to such Draw
Event plus the Prior Draw Amount with respect to such Draw Event over (ii) the
sum of the Investment Amount with respect to such Draw Event plus the Basket
Usage Amount with respect to such Draw Event shall, to the extent available
and as specified in the applicable Draw Certificate (or, in the absence of
such Draw Certificate, as specified by the Agent), count against the Borrower
Intercompany Debt Basket, the General Debt Basket and/or the Restricted
Borrower Distribution Basket.  In the event the aggregate amount then
available under the Borrower Intercompany Debt Basket, the General Debt Basket
and/or the Restricted Borrower Distribution Basket is less than the excess
referred to in the immediately preceding sentence, the Borrower agrees that it
will use its best efforts to obtain, within ten Business Days after notice of
the applicable Draw Event shall have been given to it, a cash capital
contribution from its parent and/or cash proceeds of Subordinated Intercompany
Debt provided by ADT Limited or Wholly Owned Subsidiaries of ADT Limited
(other than Subsidiaries of the Borrower) to the extent permitted by clause
(m) of Section 8.2.2 in an aggregate amount equal to or greater than such
excess.  The failure of the Borrower to obtain such amount and provide to the
Agent a certificate executed by its chief financial Authorized Officer
certifying as to its receipt of such amount within such ten day period shall
constitute an Event of Default (regardless of whether the Borrower has used
its best efforts).

       SECTION 8.1.4.  Syndication.  Solely for the benefit of the Agent and
the Lenders on the Closing Date, the Borrower acknowledges its agreements
under the Commitment Letter with respect to the syndication of Scotiabank's
Revolving Loan Commitment, Revolving Loans and Letter of Credit Outstandings,
which agreements are incorporated herein by this reference, including its
agreements to assist Scotiabank in such syndication and to limit (as set forth
in the Commitment Letter) the arrangement of any other syndicated or
multi-bank financing for it or any of its Affiliates (exclusive of the U.K.
Credit Facility (as defined in the ADT Limited Guaranty) currently in
syndication) and the offering, placement or arrangement of any of its or its
Affiliates' debt or equity securities prior to the completion of such
syndication.

       SECTION 8.2.  Negative Covenants.  The Borrower agrees with the Agent
and each Lender that, until the Covenant Termination Date, the Borrower will
perform the obligations set forth in this Section 8.2.

       SECTION 8.2.1.  Business Activities.  The Borrower will not, and will
not permit any of its Subsidiaries to, engage in any business activity, except
for those activities conducted in respect of the Core Businesses and the
businesses identified in Item 8.2.1 ("Permitted Existing Business Activities")
of the Disclosure Schedule, and such activities as may be incidental or
related thereto; provided, however, that the Borrower will not be in default
in the observance of this Section 8.2.1 if, as part of the acquisition of a
Core Business, the Borrower or its applicable Subsidiary acquires a business
or assets that would not constitute, or be included in, a Core Business, so
long as (i) the primary purpose of such acquisition was the acquisition of
such Core Business, which acquisition could not have been consummated on as
commercially attractive terms without the acquisition of such other business
or assets, (ii) not less than 70% of the assets acquired pursuant to such
acquisition related at the time of such acquisition to such Core Business,
(iii) the Borrower or such applicable Subsidiary is diligently pursuing the
sale of such other business or assets and (iv) such business or assets do not
have, and could not reasonably be expected to have, a material adverse effect
on the business, results of operations, financial condition or prospects of
the Borrower and its Subsidiaries taken as a whole.

       SECTION 8.2.2.  Indebtedness.  The Borrower will not, and will not
permit any of its Subsidiaries to, create, incur, assume or suffer to exist or
otherwise become or be liable in respect of any Indebtedness, other than,
without duplication, the following:

             (a)     Indebtedness in respect of the Credit Extensions and
       other Obligations;

             (e)     Indebtedness in respect of the Senior Note Guarantees to
       the extent the guarantor under any such Senior Note Guarantee is

             (f)     (i) Indebtedness existing as of June 30, 1995; provided

                                   ARTICLE X

                                   THE AGENT

       SECTION 10.1.  Actions.  Each Lender hereby appoints Scotiabank as its
agent under and for purposes of this Agreement, the Notes and each other Loan
Document.  Each Lender authorizes the Agent to act on behalf of such Lender
under this Agreement, the Notes and each other Loan Document and, in the
absence of other written instructions from the Required Lenders received from
time to time by the Agent (and the Agent hereby agrees that it will comply,
except as otherwise provided in this Section or as otherwise advised by
independent counsel of nationally recognized standing, with such written
instructions), to exercise such powers hereunder and thereunder as are
specifically delegated to or required of the Agent by the terms hereof and
thereof, together with such powers as may be reasonably incidental thereto.
Each Lender hereby indemnifies the Agent and each Issuer (which indemnities
shall survive any termination of this Agreement and shall be pro rata
according to such Lender's Percentage), from and against any and all
liabilities, obligations, losses, damages, claims, costs or expenses of any
kind or nature whatsoever which may at any time be imposed on, incurred by, or
asserted against, the Agent or any Issuer in any way relating to or arising
out of this Agreement, the Notes and any other Loan Document, including
reasonable attorneys' fees, and as to which the Agent is not reimbursed by the
Borrower; provided, however, that no Lender shall be liable for the payment
of any portion of such liabilities, obligations, losses, damages, claims,
costs or expenses which are determined by a court of competent jurisdiction to
have resulted from the Agent's gross negligence or wilful misconduct.  The
Agent shall not be required to take any action hereunder, under the Notes or
under any other Loan Document, or to prosecute or defend any suit in respect of
this Agreement, the Notes or any other Loan Document, unless it is indemnified
hereunder to its satisfaction.  If any indemnity in favor of the Agent shall
be or become, in the Agent's determination, inadequate, the Agent may call for
additional indemnification from the Lenders and cease to do the acts
indemnified against hereunder until such additional indemnity is given.

       SECTION 10.2.  Funding Reliance, etc.  Unless the Agent shall have been
notified by telephone, confirmed in writing, by 5:00 p.m., New York City time,
on the day prior to a Borrowing by any Lender that is to participate in such
Borrowing that such Lender will not make available the amount which would
constitute its portion of such Borrowing on the date specified therefor, the
Agent may assume that such Lender has made such amount available to the Agent
and, in reliance upon such assumption, make available to the Borrower a
corresponding amount.  If and to the extent that such Lender shall not have
made such amount available to the Agent, such Lender and the Borrower
severally agree to repay the Agent forthwith on demand such corresponding
amount together with interest thereon, for each day from the date the Agent
made such amount available to the Borrower to the date such amount is repaid
to the Agent, at, in the case of the Borrower, the interest rate applicable at
the time to Loans comprising such Borrowing, and, in the case of such Lender,
the Federal Funds Effective Rate.

       SECTION 10.3.  Exculpation.  None of the Agent, the Issuers or any of
their respective directors, officers, employees or agents shall be liable to
any Lender for any action taken or omitted to be taken by it under this
Agreement or any other Loan Document, or in connection herewith or therewith,
except for its own wilful misconduct or gross negligence, nor responsible for
any recitals or warranties herein or therein, nor for the effectiveness,
enforceability, validity or due execution of this Agreement or any other Loan
Document, or the validity, genuineness, enforceability, existence, value or
sufficiency of any collateral security, nor to make any inquiry respecting the
performance by the Borrower of its obligations hereunder or under any other
Loan Document.  Any such inquiry which may be made by the Agent or an Issuer
shall not obligate the Agent or such Issuer, as the case may be, to make any
further inquiry or to take any action.  The Agent and each Issuer shall be
entitled to rely upon advice of counsel concerning legal matters and upon any
notice, consent, certificate, statement or writing which the Agent or such
Issuer believes to be genuine and to have been presented by a proper Person.

       SECTION 10.4.  Successor.  The Agent may resign as such at any time
upon at least 30 days' prior notice to the Borrower and all Lenders.  If the
Agent at any time shall resign, (i) the Required Lenders may appoint another
Lender as successor Agent which shall thereupon become the Agent hereunder and
(ii) if no successor Agent shall have been so appointed by the Required
Lenders, and shall have accepted such appointment, within 30 days after the
retiring Agent's giving notice of resignation, then the retiring Agent may, on
behalf of the Lenders, appoint a successor Agent, which shall be one of the
Lenders or a commercial banking institution organized under the laws of the
U.S. (or any State thereof) or a U.S. branch or agency of a commercial banking
institution, and having a combined capital and surplus of at least
$500,000,000; provided that if any such successor Agent is organized under the
laws of any jurisdiction other than the United States or any state thereof or
is beneficially owned or controlled by a person so organized, such successor
Agent shall execute such documents and instruments, if any, as may be required
by the United States Department of Defense.  Upon the acceptance of any
appointment as the Agent hereunder by a successor Agent, such successor Agent
shall be entitled to receive from the retiring Agent such documents of
transfer and assignment as such successor Agent may reasonably request, and
shall thereupon succeed to and become vested with all rights, powers,
privileges and duties of the retiring Agent, and the retiring Agent shall be
discharged from its duties and obligations under this Agreement.  After any
retiring Agent's resignation hereunder as the Agent, the provisions of

             (a)     this Article X shall inure to such retiring Agent's
       benefit as to any actions taken or omitted to be taken by it while it
       was the Agent under this Agreement; and

             (b)     Section 11.3 and Section 11.4 shall continue to inure to
       such retiring Agent's benefit.

       SECTION 10.5.  Loans or Letters of Credit Issued by Scotiabank.
Scotiabank has the same rights and powers with respect to (x) the Loans made
by it or any of its Affiliates, (y) the Notes held by it or any of its
Affiliates, and (z) its participating interests in the Letters of Credit as
any other Lender and may exercise the same as if it were not the Agent.
Scotiabank and each of Scotiabank's Affiliates may accept deposits from, lend
money to, and generally engage in any kind of business with the Borrower or
any Subsidiary or Affiliate of the Borrower as if Scotiabank were not the
Agent hereunder.

       SECTION 10.6.  Credit Decisions.  Each Lender acknowledges that it has,
independently of the Agent and each other Lender, and based on such Lender's
review of the financial information of the Borrower, this Agreement, the other
Loan Documents (the terms and provisions of which being satisfactory to such
Lender) and such other documents, information and investigations as such
Lender has deemed appropriate, made its own credit decision to extend its
Revolving Loan Commitment.  Each Lender also acknowledges that it will,
independently of the Agent and each other Lender, and based on such other
documents, information and investigations as it shall deem appropriate at any
time, continue to make its own credit decisions as to exercising or not
exercising from time to time any rights and privileges available to it under
this Agreement or any other Loan Document.

       SECTION 10.7.  Copies, etc.  The Agent shall give prompt notice to each
Lender of each notice or request required or permitted to be given to the
Agent by the Borrower pursuant to the terms of this Agreement (unless
concurrently delivered to the Lenders by the Borrower).  The Agent will
distribute to each Lender each document or instrument received for its account
and copies of all other communications received by the Agent from the Borrower
for distribution to the Lenders by the Agent in accordance with the terms of
this Agreement.


                                  ARTICLE XI

                           MISCELLANEOUS PROVISIONS

       SECTION 11.1.  Waivers, Amendments, etc.  (a)  The provisions of this
Agreement and of each other Loan Document may from time to time be amended,
modified or waived, if such amendment, modification or waiver is in writing
and consented to by the Borrower and the Required Lenders; provided, however,
that no such amendment, modification or waiver shall:

             (i)  modify any requirement hereunder that any particular action
       be taken by all the Lenders or by the Required Lenders, modify this
       Section 11.1(a) or change the definition of "Required Lenders", or
       release ADT Limited from its guarantee of the Obligations of the
       Borrower under Section 2.1 of the ADT Limited Guaranty, unless consented
       to by each Lender;

             (ii)  increase any Revolving Loan Commitment Amount with respect
       to such Lender or the Percentage of any Lender, reduce any fees (or
       extend any payment date therefor) described in Article III payable to
       any Lender or extend the Revolving Loan Commitment Termination Date with
       respect to any Lender, without the consent of such Lender;

             (iii)  extend the due date for, or reduce the amount of, any
       scheduled repayment of principal of or interest on any Loan (or reduce
       the principal amount of or rate of interest on any Loan), without the
       consent of the holder of the Note evidencing such Loan;

             (iv)  affect adversely the interests, rights or obligations of
       any Issuer qua Issuer, without the consent of such Issuer; or

             (v)  affect adversely the interests, rights or obligations of the
       Agent qua Agent, without the consent of the Agent.

       (b)  No failure or delay on the part of the Agent, any Lender or the
holder of any Note in exercising any power or right under this Agreement or
any other Loan Document shall operate as a waiver thereof, nor shall any
single or partial exercise of any such power or right preclude any other or
further exercise thereof or the exercise of any other power or right.  No
notice to or demand on the Borrower in any case shall entitle it to any notice
or demand in similar or other circumstances.  No waiver or approval by the
Agent, any Lender or the holder of any Note under this Agreement or any other
Loan Document shall, except as may be otherwise stated in such waiver or
approval, be applicable to subsequent transactions.  No waiver or approval
hereunder shall require any similar or dissimilar waiver or approval thereafter
to be granted hereunder.

       SECTION 11.2.  Notices.  All notices and other communications provided
to any party hereto under this Agreement or any other Loan Document shall be
in writing or by facsimile and addressed, delivered or transmitted to such
party at its address or facsimile number set forth below its signature hereto
or set forth in the Lender Assignment Agreement or at such other address or
facsimile number as may be designated by such party in a notice to the other
parties.  Any notice, if mailed and properly addressed with postage prepaid,
return receipt requested, or if properly addressed and sent by pre-paid courier
service, shall be deemed given when received; any notice, if transmitted by
facsimile, shall be deemed given when transmitted upon receipt of electronic
confirmation of transmission (it being understood and agreed that notice
transmitted by facsimile to ADT Inc. shall constitute notice to the Borrower
hereunder).

       SECTION 11.3.  Payment of Costs and Expenses.  The Borrower agrees to
pay on demand all reasonable out-of-pocket expenses of the Agent (including
the fees and out-of-pocket expenses of counsel to the Agent (and of local
counsel, if any, who may be retained by such counsel)) in connection with

             (a)     the negotiation, preparation, execution and delivery of
       this Agreement and of each other Loan Document, including schedules and
       exhibits, and any amendments, waivers, consents, supplements or other
       modifications to this Agreement or any other Loan Document as may from
       time to time hereafter be required, whether or not the transactions
       contemplated hereby are consummated, and

             (b)     the preparation and review of the form of any document or
       instrument relevant to this Agreement or any other Loan Document.

The Borrower further agrees to pay, and to save the Agent and the Lenders
harmless from all liability for, any stamp or other similar taxes which may be
payable in connection with the execution or delivery of this Agreement, the
borrowings hereunder, the issuance of the Notes, the issuance of the Letters
of Credit, or any other Loan Documents.  The Borrower also agrees to reimburse
the Agent and each Lender upon demand for all reasonable out-of-pocket
expenses (including attorneys' fees and legal expenses) incurred by the Agent
or such Lender in connection with (x) the negotiation of any restructuring or
"work-out", whether or not consummated, of any Obligations and (y) the
enforcement of any Obligations.

       SECTION 11.4.  Indemnification.  In consideration of the execution and
delivery of this Agreement by each Lender and the extension of the Revolving
Loan Commitments, the Borrower hereby indemnifies, exonerates and holds the
Agent, each Issuer and each Lender and each of their respective officers,
directors, employees and agents (collectively, the "Indemnified Parties") free
and harmless from and against any and all actions, causes of action, suits,
losses, costs, liabilities and damages, and expenses incurred in connection
therewith (irrespective of whether any such Indemnified Party is a party to
the action for which indemnification hereunder is sought), including reasonable
attorneys' fees and disbursements (collectively, the "Indemnified
Liabilities"), incurred by the Indemnified Parties or any of them as a result
of, or arising out of, or relating to

             (a)     any transaction financed or to be financed in whole or in
       part, directly or indirectly, with the proceeds of any Loan or the use
       of any Letter of Credit;

             (b)     the entering into and performance of this Agreement and
       any other Loan Document by any of the Indemnified Parties (including
       any action brought by or on behalf of the Borrower as the result of any
       determination by the Required Lenders pursuant to Article VI not to make
       any Credit Extension);

             (c)     any investigation, litigation or proceeding related to
       any environmental cleanup, audit, compliance or other matter relating
       to the protection of the environment or the Release by the Borrower or
       any of its Subsidiaries of any Hazardous Material; or

             (d)     the presence on or under, or the escape, seepage,
       leakage, spillage, discharge, emission, discharging or releases from,
       any real property owned or operated by the Borrower or any Subsidiary
       thereof of any Hazardous Material (including any losses, liabilities,
       damages, injuries, costs, expenses or claims asserted or arising under
       any Environmental Law), regardless of whether caused by, or within the
       control of, the Borrower or such Subsidiary,

except for any such Indemnified Liabilities arising for the account of a
particular Indemnified Party by reason of the relevant Indemnified Party's
gross negligence or wilful misconduct and provided that an Indemnified Party
will not effect any settlement in connection with any such Indemnified
Liabilities without the prior written consent of the Borrower, which consent
shall not be unreasonably withheld or delayed.  If and to the extent that the
foregoing undertaking may be unenforceable for any reason, the Borrower hereby
agrees to make the maximum contribution to the payment and satisfaction of each
of the Indemnified Liabilities which is permissible under applicable law.

       SECTION 11.5.  Survival.  The obligations of the Borrower under
Sections 4.9, 5.3, 5.4, 5.5, 5.6, 11.3 and 11.4, and the obligations of the

Agreement, the payment in full of all Obligations and the termination of all
Revolving Loan Commitments.  The representations and warranties made by each
Obligor in this Agreement and in each other Loan Document shall survive the
execution and delivery of this Agreement and each such other Loan Document.

       SECTION 11.6.  Severability.  Any provision of this Agreement or any
other Loan Document which is prohibited or unenforceable in any jurisdiction
shall, as to such provision and such jurisdiction, be ineffective to the
extent of such prohibition or unenforceability without invalidating the
remaining provisions of this Agreement or such Loan Document or affecting the
validity or enforceability of such provision in any other jurisdiction.

       SECTION 11.7.  Headings.  The various headings of this Agreement and of
each other Loan Document are inserted for convenience only and shall not
affect the meaning or interpretation of this Agreement or such other Loan
Document or any provisions hereof or thereof.

Agreement may be executed by the parties hereto in several counterparts, each
of which shall be deemed to be an original and all of which shall constitute
together but one and the same agreement.  This Agreement shall become
effective when counterparts hereof executed on behalf of the Borrower and each
Lender (or notice thereof satisfactory to the Agent) shall have been received
by the Agent.

       SECTION 11.9.  Governing Law; Entire Agreement.  THIS AGREEMENT, THE
NOTES AND EACH OTHER LOAN DOCUMENT SHALL EACH BE DEEMED TO BE A CONTRACT MADE
UNDER AND GOVERNED BY THE INTERNAL LAWS OF THE STATE OF NEW YORK.  This
Agreement, the Notes, the other Loan Documents and the agreements referred to
in Sections 3.3.3, 3.3.4, 3.3.5 and 11.11.1 constitute the entire
understanding among the parties hereto with respect to the subject matter
hereof and supersede any prior agreements, written or oral, with respect
thereto.

       SECTION 11.10.  Successors and Assigns.  This Agreement shall be
binding upon and shall inure to the benefit of the parties hereto and their
respective successors and assigns; provided, however, that:

             (a)     the Borrower may not assign or transfer its rights or
       obligations hereunder without the prior written consent of the Agent
       and all Lenders; and

             (a)     with the written consents of the Borrower, the Agent and
       each Issuer (which consents shall not be unreasonably delayed or
       withheld) may at any time assign and delegate to one or more commercial
       banks or other financial institutions (provided that such consents shall
       not, except to the extent provided in the Commitment Letter, be
       required in connection with any syndication by Scotiabank of its
       Revolving Loan Commitment, Revolving Loans and Letter of Credit
       Outstandings in accordance with the provisions of the Commitment
       Letter), and

             (b)     with notice to the Borrower and the Agent, but without
       the consent of the Borrower or the Agent, may assign and delegate to
       any of its branches, agencies or Affiliates (provided a majority of the

       Lender or such Lender's holding company) or to any other Lender

(each Person described in either of the foregoing clauses as being the Person
to whom such assignment and delegation is to be made, being hereinafter
referred to as an "Assignee Lender"), (x) all or any fraction of such Lender's
Competitive Bid Loans and/or (y) all or any proportionate fraction of such
Lender's Revolving Loans, Letter of Credit Outstandings and Revolving Loan
Commitment, in each case, in a minimum aggregate amount equal to the lesser of
$5,000,000 and all of its (x) Competitive Bid Loans or (y) Revolving Loans,
Letter of Credit Outstandings and Revolving Loan Commitment, as the case may
be; provided, however, that any such Assignee Lender will comply, if
applicable, with the provisions contained in the second sentence of the last
paragraph of Section 5.6; provided further, however, that, the Borrower, each
other Obligor and the Agent shall be entitled to continue to deal solely and
directly with such Lender in connection with the interests so assigned and
delegated to an Assignee Lender until

             (i)  written notice of such assignment and delegation, together
       with payment instructions, addresses and related information with
       respect to such Assignee Lender, shall have been given to the Borrower
       and the Agent by such Lender and such Assignee Lender,

             (ii)  such Assignee Lender shall have executed and delivered to
       the Borrower and the Agent a Lender Assignment Agreement, accepted by
       the Agent, and

             (iii)  the processing fees described below shall have been paid.

From and after the date that the Agent accepts such Lender Assignment
Agreement, (x) the Assignee Lender thereunder shall be deemed automatically to
have become a party hereto and to the extent that rights and obligations
hereunder have been assigned and delegated to such Assignee Lender in
connection with such Lender Assignment Agreement, shall have the rights and
obligations of a Lender hereunder and under the other Loan Documents;
provided, that no Assignee Lender or other transferee of any Lender's rights
shall be entitled to receive any greater payment under Section 5.3, 5.5 or 5.6
than such Lender would have been entitled to receive with respect to the
rights transferred, unless such transfer is made with the Borrower's prior
written consent or at a time when the circumstances giving rise to such
greater payment did not exist, and (y) the assignor Lender, to the extent that
rights and obligations hereunder have been assigned and delegated by it in
connection with such Lender Assignment Agreement, shall be released from its
obligations hereunder and under the other Loan Documents.  Within five
Business Days after its receipt of notice that the Agent has received an
executed Lender Assignment Agreement, the Borrower shall execute and deliver
to the Agent (for delivery to the relevant Assignee Lender) new Notes
evidencing such Assignee Lender's assigned Loans and Revolving Loan Commitment
and, if the assignor Lender has retained Loans and any Revolving Loan
Commitment hereunder, replacement Notes in the principal amount of the Loans
and such Revolving Loan Commitment retained by the assignor Lender hereunder
(such Notes to be in exchange for, but not in payment of, those Notes then
held by such assignor Lender).  Each such Note shall be dated the date of the
predecessor Notes.  The assignor Lender shall mark the predecessor Notes
"exchanged" and deliver them to the Borrower.  Accrued interest on that part
of the predecessor Notes evidenced by the new Notes, and accrued fees, shall
be paid as provided in the Lender Assignment Agreement.  Accrued interest on
that part of the predecessor Notes evidenced by the replacement Notes shall
be paid to the assignor Lender.  Accrued interest and accrued fees shall be
paid at the same time or times provided in the predecessor Notes and in this
Agreement.  Such assignor Lender or such Assignee Lender must also pay a
processing fee to the Agent upon delivery of any Lender Assignment Agreement
in the amount of $3,000.  Any attempted assignment and delegation not made in
accordance with this Section 11.11.1 shall be null and void.  Notwithstanding
any provision contained in this Section 11.11.1 to the contrary, nothing shall
prevent or prohibit any Lender from pledging its rights under this Agreement
and/or its Loans and/or Notes hereunder to a Federal Reserve Bank in support of
borrowings made by such Lender from such Federal Reserve Bank; provided that
no such pledge by any Lender shall relieve such Lender of any of its
obligations hereunder.

       SECTION 11.11.2.  Participations.  Any Lender may at any time sell to
one or more commercial banks or other Persons (each of such commercial banks
and other Persons being herein called a "Participant") participating interests
(or a sub-participating interest, in the case of a Lender's participating
interest in a Letter of Credit) in any of the Loans, Revolving Loan Commitment,
or other interests of such Lender hereunder; provided, however, that

             (a)  no participation or sub-participation contemplated in this
       Section 11.11 shall relieve such Lender from its Revolving Loan
       Commitment or its other obligations hereunder or under any other Loan
       Document,

             (b)  such Lender shall remain solely responsible for the
       performance of its Revolving Loan Commitment and such other obligations,

             (c)  the Borrower and each other Obligor and the Agent shall
       continue to deal solely and directly with such Lender in connection
       with such Lender's rights and obligations under this Agreement and each
       of the other Loan Documents,

             (d)  no Participant, unless such Participant is an Affiliate of
       such Lender, or is itself a Lender, shall be entitled to require such
       Lender to take or refrain from taking any action hereunder or under any
       other Loan Document, except that such Lender may agree with any
       Participant that such Lender will not, without such Participant's
       consent, take any actions of the type described in clause (ii) or (iii)
       of Section 11.1(a), and

             (e)  the Borrower shall not be required to pay any amount under
       Section 5.6 that is greater than the amount which it would have been
       required to pay had no participating interest been sold.

The Borrower acknowledges and agrees that, to the extent permitted under
applicable law, each Participant, for purposes of Sections 5.3, 5.4, 5.5, 5.6,
5.8, 11.3 and 11.4, shall be considered a Lender; provided, that no
Participant shall be entitled to receive any greater payment under Section
5.3, 5.5 or 5.6 than the Lender that transferred such rights to such
Participant would have been entitled to receive with respect to such rights,
unless such transfer is made with the Borrower's prior written consent or at a
time when the circumstances giving rise to such greater payment did not exist.

       SECTION 11.12.  Other Transactions.  Nothing contained herein shall
preclude the Agent or any other Lender or Issuer from engaging in any
transaction, in addition to those contemplated by this Agreement or any other
Loan Document, with the Borrower or any of its Affiliates in which the
Borrower or such Affiliate is not restricted hereby from engaging with any
other Person.

       SECTION 11.13.  Independence of Covenants.  All covenants contained in
this Agreement or any other Loan Document shall be given independent effect
such that, in the event a particular action or condition is not permitted by
any of such covenants, the fact that it would be permitted by an exception to,
or be otherwise within the limitations of, another covenant shall not, unless
expressly so provided in such first covenant, avoid the occurrence of a
Default or an Event of Default if such action is taken or such condition
exists.

       SECTION 11.14.  Forum Selection and Consent to Jurisdiction.  ANY
LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS
AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF
DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTIONS OF THE AGENT, THE
LENDERS OR THE BORROWER SHALL BE BROUGHT AND MAINTAINED TO THE FULLEST EXTENT
PERMITTED BY APPLICABLE LAW EXCLUSIVELY IN THE COURTS OF THE STATE OF NEW YORK
OR IN THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK;
PROVIDED, HOWEVER, THAT ANY SUIT SEEKING ENFORCEMENT AGAINST ANY PROPERTY MAY
BE BROUGHT, AT THE AGENT'S OPTION, IN THE COURTS OF ANY JURISDICTION WHERE SUCH
PROPERTY MAY BE FOUND.  THE BORROWER HEREBY EXPRESSLY AND IRREVOCABLY SUBMITS
TO THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK AND OF THE UNITED
STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK FOR THE PURPOSE OF
ANY SUCH LITIGATION AS SET FORTH ABOVE AND IRREVOCABLY AGREES TO BE BOUND BY
ANY JUDGMENT RENDERED THEREBY IN CONNECTION WITH SUCH LITIGATION.  THE
BORROWER HEREBY IRREVOCABLY APPOINTS KAY, COLLYER & BOOSE (THE "PROCESS

YORK, NEW YORK, UNITED STATES (ATTENTION:  ELI SCHOENFIELD), AS ITS AGENT TO
RECEIVE, ON THE BORROWER'S BEHALF AND ON BEHALF OF ITS PROPERTY, SERVICE OF
COPIES OF THE SUMMONS AND COMPLAINT AND ANY OTHER PROCESS WHICH MAY BE SERVED
IN ANY SUCH ACTION OR PROCEEDING.  SUCH SERVICE MAY BE MADE BY MAILING OR
DELIVERING A COPY OF SUCH PROCESS TO THE BORROWER IN CARE OF THE PROCESS AGENT
AT THE PROCESS AGENT'S ABOVE ADDRESS, AND THE BORROWER HEREBY IRREVOCABLY
AUTHORIZES AND DIRECTS THE PROCESS AGENT TO ACCEPT SUCH SERVICE ON ITS BEHALF.
AS AN ALTERNATIVE METHOD OF SERVICE, THE BORROWER ALSO IRREVOCABLY CONSENTS TO
THE SERVICE OF PROCESS BY REGISTERED MAIL, POSTAGE PREPAID, OR BY PERSONAL
SERVICE WITHIN OR WITHOUT THE STATE OF NEW YORK.  THE BORROWER HEREBY AGREES
THAT IN THE EVENT THE PROCESS AGENT IS NO LONGER RESIDENT IN NEW YORK, NEW
YORK, IT SHALL APPOINT A SUCCESSOR PROCESS AGENT RESIDENT IN NEW YORK, NEW
YORK, REASONABLY ACCEPTABLE TO THE AGENT, WHICH SUCCESSOR PROCESS AGENT SHALL
THEREAFTER BE THE PROCESS AGENT HEREUNDER.  THE BORROWER HEREBY EXPRESSLY AND
IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION
WHICH IT MAY HAVE OR HEREAFTER MAY HAVE TO THE LAYING OF VENUE OF ANY SUCH
LITIGATION BROUGHT IN ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM THAT ANY
SUCH LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.  TO THE EXTENT THAT
THE BORROWER HAS OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM JURISDICTION OF
ANY COURT OR FROM ANY LEGAL PROCESS (WHETHER THROUGH SERVICE OR NOTICE,
ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION OR OTHERWISE)
WITH RESPECT TO ITSELF OR ITS PROPERTY, THE BORROWER HEREBY IRREVOCABLY WAIVES
TO THE FULLEST EXTENT PERMITTED BY LAW SUCH IMMUNITY IN RESPECT OF ITS
OBLIGATIONS UNDER THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS.

       SECTION 11.15.  Waiver of Jury Trial.  THE AGENT, THE LENDERS AND THE
BORROWER HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHTS THEY
MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR
ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR ANY OTHER LOAN
DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER
ORAL OR WRITTEN) OR ACTIONS OF THE AGENT, THE LENDERS OR THE BORROWER.  THE
BORROWER ACKNOWLEDGES AND AGREES THAT IT HAS RECEIVED FULL AND SUFFICIENT
CONSIDERATION FOR THIS PROVISION (AND EACH OTHER PROVISION OF EACH OTHER LOAN
DOCUMENT TO WHICH IT IS A PARTY) AND THAT THIS PROVISION IS A MATERIAL
INDUCEMENT FOR THE AGENT AND THE LENDERS ENTERING INTO THIS AGREEMENT AND EACH
SUCH OTHER LOAN DOCUMENT.

       IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed by their respective officers thereunto duly authorized as of the day
and year first above written.

            3.  PRIORITY AND PAYMENT OVER IN CERTAIN EVENTS.

                  (a)  Subordination On Dissolution, Liquidation or
            Reorganization of any Debtor.  Upon any payment or distribution of
            assets or securities of any Debtor of any kind or character

            insolvency, receivership or other proceeding, or any assignment
            for the benefit of creditors or any marshalling of assets and
            liabilities of any Debtor (each such event, an "Insolvency
            Event"), all Senior Indebtedness shall first be paid in full in
            cash, before any Creditor shall be entitled to receive, directly or
            indirectly, any payment of the principal of, premium, if any, or
            interest on or any other amount due with respect to any
            Subordinated Intercompany Debt or to receive any distribution of
            any assets or securities.  Before any payment of the principal of,
            premium, if any, or interest on or any other amount due with
            respect to any Subordinated Intercompany Debt upon any such
            Insolvency Event, any payment or distribution of assets or
            securities of such Debtor of any kind or character (whether in
            cash, property or securities) to which any Creditor would be
            entitled but for the subordination provisions hereof, shall be
            made by such Debtor or by any receiver, trustee in bankruptcy,
            liquidating trustee, agent or other person making such payment or
            distribution directly to the holders of Senior Indebtedness or
            their representatives to the extent necessary to pay the Senior
            Indebtedness in full in cash after giving effect to any concurrent
            payment or distribution to the holders thereof.

                  (b)  Subordination on Default in Senior Indebtedness.  If
            there exists any default under the documents and instruments
            evidencing any Senior Indebtedness, (i) no direct or indirect
            payment by or on behalf of any Debtor of any Subordinated
            Intercompany Debt or any other amount due with respect to such
            Subordinated Intercompany Debt shall be made and (ii) no Creditor
            will accelerate or declare in default any Subordinated
            Intercompany Debt or exercise any remedies with respect thereto,
            unless otherwise agreed to by the requisite holders of such Senior
            Indebtedness pursuant to the terms of the documents and
            instruments evidencing such Senior Indebtedness.

                  (c)  Payment After Acceleration.  In the event that any
            Senior Indebtedness (or any part thereof) is declared due and
            payable before its stated maturity or is not paid at its stated
            maturity, then and in such event the holders of Senior
            Indebtedness at the time such Senior Indebtedness so becomes due
            and payable shall be entitled to receive payment in full in cash
            of all amounts due or to become due on or in respect of all such
            Senior Indebtedness before any Creditor is entitled to receive any
            payment in respect of any Subordinated Intercompany Debt.

                  (d)  Rights and Obligations of the Creditors.  If,
            notwithstanding the foregoing provisions of this Section 3
            prohibiting such payment or distribution, any Creditor shall have
            received any payment on account of any Subordinated Intercompany
            Debt at a time when such payment is prohibited by the
            subordination provisions contained herein and before all Senior
            Indebtedness is paid in full in cash, then such payment or
            distribution shall be received and held in trust for the holders
            of Senior Indebtedness and shall be paid over or delivered to such
            holders remaining unpaid to the extent necessary to pay in full
            all Senior Indebtedness in cash, in accordance with their terms
            after giving effect to any concurrent payment or distribution to
            the holders of Senior Indebtedness.

            4.  RIGHTS OF HOLDERS OF SENIOR INDEBTEDNESS IN AN INSOLVENCY
EVENT.  If the Senior Indebtedness has not been paid in full in cash at a time
at which the Debtor is subject to an Insolvency Event, (a) the holders of
Senior Indebtedness are hereby irrevocably authorized, but shall have no
obligation, to demand, sue for, collect and receive every payment or
distribution received in respect of any such Insolvency Event and give
acquittance therefor and to file claims and proofs of claim, as their interests
may appear, and (b) the appropriate Creditor shall duly and promptly take, for
the account of the holders of Senior Indebtedness as their interests may
appear, such actions as such holders may request to collect and receive all
amounts payable by such Debtor, as the case may be, in respect of any
Subordinated Intercompany Debt and to file appropriate claims or proofs of
claim in respect of any Subordinated Intercompany Debt.

            5.  RIGHTS OF HOLDERS OF SENIOR INDEBTEDNESS NOT TO BE IMPAIRED.
No right of any holder of Senior Indebtedness to enforce subordination as
herein provided shall at any time or in any way be prejudiced or impaired by
any failure to act by any other such holder or by any noncompliance by the
Debtor with the terms and provisions and covenants contained in any document
or instrument evidencing Senior Indebtedness (or any document related thereto)
to which it is a party regardless of any knowledge thereof a holder of Senior
Indebtedness may have or otherwise be charged with.  The provisions contained
herein are intended to be for the benefit of, and shall be enforceable
directly by, each holder of Senior Indebtedness.

            6.  SUBROGATION.   (a)  Each Creditor hereby agrees that it will
not exercise any rights of subrogation until the payment in full in cash of all
Senior Indebtedness.

            (b)  Payments or distributions made to the holders of Senior
Indebtedness pursuant to the terms hereof shall not, as against third parties,
be construed as a discharge of the indebtedness represented by any Subordinated
Intercompany Debt.

            7.  LIMITATION ON OTHER ACTIONS.  (a)  Each Creditor hereby agrees
to forbear and not take any action, the purpose or effect of which would give
it a preference or priority over the Senior Indebtedness or the holders
thereof with respect to the assets of the Debtor.

            (b)  Without limiting the effect of Section 3(b), each Creditor
hereby agrees to forebear and not accelerate or declare in default any
Subordinated Intercompany Debt or exercise any remedies with respect thereto
without giving the applicable representatives of the holders of Senior
Indebtedness (which, in the case of the Bank Credit Agreement, shall be the
Agent) 45 days prior written notice.

                              GUARANTY PROVISIONS

            SECTION 2.1.  Guaranty.  ADT Limited hereby absolutely,
unconditionally and irrevocably

                  (a)  guarantees the full and punctual payment when due,
            whether at stated maturity, by required prepayment, declaration,
            acceleration, demand or otherwise, of all Obligations of the
            Borrower and each other Obligor now or hereafter existing, whether
            for principal, interest, Reimbursement Obligations, fees, expenses
            or otherwise (including all such amounts which would become due
            but for the operation of the automatic stay under Section 362(a)
            of the United States Bankruptcy Code, 11 U.S.C. Section  362(a),
            and the operation of Sections 502(b) and 506(b) of the United
            States Bankruptcy Code, 11 U.S.C. Section  502(b) and Section
            506(b)); and

                  (b)  indemnifies and holds harmless each Lender Party and
            each holder of a Note for any and all costs and expenses (including
            reasonable attorney's fees and expenses) incurred by such Lender
            Party or such holder, as the case may be, in enforcing any rights
            under this Guaranty.

This Guaranty constitutes a guaranty of payment when due and not of
collection, and ADT Limited specifically agrees that it shall not be necessary
or required that any Lender Party or any holder of any Note exercise any
right, assert any claim or demand or enforce any remedy whatsoever against the
Borrower or any other Obligor (or any other Person) before or as a condition
to the obligations of ADT Limited hereunder.

            SECTION 2.2.  Guaranty Absolute, etc.  This Guaranty shall in all
respects be a continuing, absolute, unconditional and irrevocable guaranty of
payment, and shall remain in full force and effect until all Obligations of the
Borrower and each other Obligor have been paid in full, all obligations of ADT
Limited hereunder shall have been paid in full and all Commitments shall have
terminated.  ADT Limited guarantees that the Obligations of the Borrower and
each other Obligor and their respective Subsidiaries will be paid strictly in
accordance with the terms of the Credit Agreement and each other Loan Document
under which they arise, without regard (to the fullest extent permitted under
applicable law) to any law, regulation or order now or hereafter in effect in
any jurisdiction affecting any of such terms or the rights of any Lender Party
or any holder of any Note with respect thereto (and ADT Limited hereby waives
to the fullest extent it may do so any right or rights it may have under any
such law, regulation or order).  Without limiting the generality of the
foregoing, the liability of ADT Limited under this Guaranty shall be absolute,
unconditional and irrevocable irrespective of:

                  (a)  any lack of genuineness, validity, legality or
            enforceability of the Credit Agreement, any Note, any Letter of
            Credit or any other Loan Document (other than this Guaranty) or of
            any of the Obligations (other than the Obligations of ADT Limited
            hereunder);

                  (b)  the failure of any Lender Party or any holder of any
            Note

                        (i)  to assert any claim or demand or to enforce any
                  right or remedy against the Borrower, any other Obligor or
                  any other Person (including any other guarantor) under the
                  provisions of the Credit Agreement, any Note, any Letter of
                  Credit, any other Loan Document or otherwise, or

                        (ii)  to exercise any right or remedy against any other
                  guarantor (including any other Guarantor) of, or collateral
                  securing, any Obligations of the Borrower or any other
                  Obligor;

                  (c)  any change in the time, manner or place of payment of,
            or in any other term of, all or any of the Obligations of the
            Borrower or any other Obligor (other than ADT Limited), or any
            other extension, compromise or renewal of any Obligation of the
            Borrower or any other Obligor (other than ADT Limited);

                  (d)  any reduction, limitation, impairment or termination of
            the Obligations of the Borrower or any other Obligor (other than
            ADT Limited) for any reason, including any claim of waiver,
            release, surrender, alteration or compromise, and shall not be
            subject to (and ADT Limited hereby waives any right to or claim
            of) any defense or setoff, counterclaim, recoupment or termination
            whatsoever by reason of the invalidity, illegality,
            nongenuineness, irregularity, compromise, unenforceability of, or
            any other event or occurrence affecting, the Obligations of the
            Borrower, any other Obligor (other than ADT Limited) or otherwise;

                  (e)  any amendment to, rescission, waiver, or other
            modification of, or any consent to departure from, any of the
            terms of the Credit Agreement, any Note, any Letter of Credit or
            any other Loan Document (other than this Guaranty);

                  (f)  any addition, exchange, release, surrender or
            non-perfection of any collateral, or any amendment to or waiver or
            release or addition of, or consent to departure from, any other
            guaranty (or any other Guarantee), held by any Lender Party or any
            holder of any Note securing any of the Obligations of the Borrower
            or any other Obligor; or

                  (g)  any other circumstance which might otherwise constitute
            a defense available to, or a legal or equitable discharge of, the
            Borrower, any other Obligor, any surety or any other guarantor (or
            any other Guarantor).

            SECTION 2.3.  Stay of Acceleration, Reinstatement, etc.  ADT
Limited agrees that, if acceleration of the time for payment of any amount
payable by the Borrower under the Credit Agreement, the Notes or any other
Loan Document or of compliance by the Borrower with its obligations under
Section 4.7 of the Credit Agreement is, in either case, stayed upon the
occurrence with respect to the Borrower of any Event of Default described in
clause (b) or (d) of Section 9.1.9 of the Credit Agreement, all such amounts
and obligations otherwise subject to acceleration or compliance under the terms
of the Credit Agreement shall nonetheless be payable and performed by ADT
Limited hereunder forthwith on demand by the Agent made at the request of the
requisite proportion of the Lenders specified in Section 9.3 of the Credit
Agreement.  ADT Limited agrees that this Guaranty shall continue to be
effective or be reinstated, as the case may be, if at any time any payment (in
whole or in part) of any of the Obligations is rescinded or must otherwise be
restored by any Lender Party or any holder of any Note, upon the insolvency,
bankruptcy or reorganization of the Borrower, any other Obligor (other than
ADT Limited) or otherwise, all as though such payment had not been made.

            SECTION 2.4.  Waiver, etc.  ADT Limited hereby waives  promptness,
diligence, notice of acceptance and any other notice with respect to any of
the Obligations of the Borrower or any other Obligor and this Guaranty and any
requirement that any Agent, any other Lender Party or any holder of any Note
protect, secure, perfect or insure any security interest or Lien, or any
property subject thereto, or exhaust any right or take any action against the
Borrower, any other Obligor or any other Person (including any other guarantor
and any other Guarantor) or entity or any collateral securing the Obligations
of the Borrower or any other Obligor, as the case may be.

            SECTION 2.5.  Subrogation.  ADT Limited hereby agrees that it will
not exercise any rights which it may now or hereafter acquire against the
Borrower or any other Obligor that arise from the existence, payment,
performance or enforcement of ADT Limited's obligations under this Guaranty
or any other Loan Document, including any right of subrogation, reimbursement,
exoneration, or indemnification, any right to participate in any claim or
remedy of the Lender Parties against the Borrower or any other Obligor or any
collateral which any Agent now has or hereafter acquires, whether or not such
claim, remedy or right arises in equity, or under contract, statute or common
law, including the right to take or receive from the Borrower or any other
Obligor, directly or indirectly, in cash or other property  or by set-off or
in any manner, payment or security on account of such claim or other rights,
until the Obligations have been paid in full in cash and the Commitments have
been terminated.  If any amount shall be paid to ADT Limited in violation of
the preceding sentence and the Obligations shall not have been paid in cash in
full and the Commitments have not been terminated, such amount shall be deemed
to have been paid to ADT Limited for the benefit of, and held in trust for,
the Lender Parties, and shall forthwith be paid to the Lender Parties to be
credited and applied to the Obligations, whether matured or unmatured.  ADT
Limited acknowledges that it will receive direct and indirect benefits from
the financing arrangements contemplated by the Credit Agreement and that the
agreement set forth in this Section is knowingly made in contemplation of such
benefits.

            SECTION 2.6.  Successors, Transferees and Assigns; Transfers of
Notes, etc.  This Guaranty shall:

                  (a)  be binding upon ADT Limited, and its successors,
            transferees and assigns; and

                  (b)  inure to the benefit of and be enforceable by the Agent
            and each other Lender Party.

Without limiting the generality of clause (b), any Lender may assign or
otherwise transfer (in whole or in part) any Note or Loan held by it to any
other Person or entity, and such other Person or entity shall thereupon become
vested with all rights and benefits in respect thereof granted to such Lender
under any Loan Document (including this Guaranty) or otherwise, subject,
however, to the provisions of Section 11.11 and Article X of the Credit
Agreement.

            SECTION 2.7.  Payments Free and Clear of Taxes, etc.  ADT Limited
hereby agrees that:

                  (a)  Any and all payments made by ADT Limited hereunder
            shall be made in accordance with Section 5.6 of the Credit
            Agreement free and clear of, and without deduction for, any and
            all present or future taxes, levies, imposts, deductions, charges
            or withholdings, and all liabilities with respect thereto,
            excluding, in the case of each Lender Party or any holder of a
            Note, taxes imposed on its income, and franchise taxes imposed on
            it, by the jurisdiction under the laws of which such Lender Party
            or such holder, as the case may be, is organized and by any
            political subdivision thereof and, in the case of each Lender,
            taxes imposed on its income, and franchise taxes imposed on it, by
            the jurisdiction of such Lender's Domestic Office or LIBOR Office
            and any political subdivision thereof (all such non-excluded
            taxes, levies, imposts, deductions, charges, withholdings and
            liabilities being hereinafter referred to as "Taxes").  If ADT
            Limited shall be required by law to deduct any Taxes from or in
            respect of any sum payable hereunder to any Lender Party or any
            holder of a Note

                        (i)  the sum payable shall be increased as may be
                  necessary so that after making all required deductions
                  (including deductions applicable to additional sums payable
                  under this Section) such Lender Party or such holder, as the
                  case may be, receives an amount equal to the sum it would
                  have received had no such deductions been made,

                        (ii)  ADT Limited shall make such deductions, and

                        (iii) ADT Limited shall pay the full amount deducted
                  to the relevant taxation authority or other authority in
                  accordance with applicable law.

                  (b)  ADT Limited shall pay any present or future stamp or
            documentary taxes or any other excise or property taxes, charges or
            similar levies which arise from any payment made hereunder or from
            the execution, delivery or registration of, or otherwise with
            respect to, this Guaranty (hereinafter referred to as "Other
            Taxes").

                  (c)  ADT Limited hereby indemnifies and holds harmless each
            Lender Party and each holder of a Note for the full amount of
            Taxes or Other Taxes (including, without limitation, any Taxes or
            Other Taxes imposed by any jurisdiction on amounts payable under
            this Section) paid by such Lender Party or such holder, as the
            case may be, and any liability (including penalties, interest and
            expenses) arising therefrom or with respect thereto, whether or
            not such Taxes or Other Taxes were correctly or legally asserted.

                  (d)  Within 30 days after the date of any payment of Taxes or
            Other Taxes, ADT Limited will furnish to the Agent the original or
            a certified copy of a receipt evidencing payment thereof.  If no
            Taxes or Other Taxes are payable in respect of any payment
            hereunder to any Lender Party or any holder of a Note, ADT Limited
            will furnish to the Agent upon its reasonable request (which
            request shall not be made more than once per Fiscal Year) a
            certificate from each appropriate taxing authority, or an opinion
            of counsel acceptable to the Agent, in either case stating that
            such payment is exempt from or not subject to Taxes or Other Taxes.

                  (e)  Without prejudice to the survival of any other
            agreement of ADT Limited hereunder, the agreements and obligations
            of ADT Limited contained in this Section 2.7 shall survive the
            payment in full of the principal of and interest on the Loans.

            SECTION 2.8.  Judgment.  ADT Limited hereby agrees that to the
fullest extent permitted by applicable law:

                  (a)  if, for the purposes of obtaining judgment in any
            court, it is necessary to convert a sum due hereunder in United
            States Dollars into another currency, ADT Limited agrees that the
            rate of exchange used shall be that at which in accordance with
            normal banking procedures the Agent could purchase United States
            Dollars with such other currency on the Business Day preceding
            that on which final judgment is given; and

                  (b)  the obligation of ADT Limited in respect of any sum due
            from it to any Lender Party or any holder of a Note hereunder
            shall, notwithstanding any judgment in a currency other than
            United States Dollars, be discharged only to the extent that on
            the Business Day following receipt by such Lender Party or such
            holder, as the case may be, of any sum adjudged to be so due in
            such other currency such Lender Party or such holder, as the case
            may be, may, in accordance with normal banking procedures,
            purchase United States Dollars with such other currency; in the
            event that the United States Dollars so purchased are less than
            the sum originally due to such Lender Party in United States
            Dollars, ADT Limited, as a separate obligation and notwithstanding
            any such judgment, hereby indemnifies and holds harmless such
            Lender Party and such holder against such loss, and if the United
            States Dollars so purchased exceed the sum originally due to such
            Lender Party or such holder in United States Dollars, such Lender
            Party or such holder, as the case may be, shall remit to ADT
            Limited such excess.

            SECTION 2.9.  Consent to Jurisdiction; Waiver of Immunities.  ADT
Limited hereby acknowledges and agrees that:

                  (a)  It has irrevocably submitted to the jurisdiction of the
            courts of the State of New York and of the United States District
            Court for the Southern District of New York for the purposes of
            any action or proceeding arising out of or relating to this
            Guaranty, and ADT Limited hereby irrevocably agrees that all
            claims in respect of such action or proceeding may be heard and
            determined in such New York state or federal court.  ADT Limited
            hereby irrevocably waives, to the fullest extent it may
            effectively do so, the defense of an inconvenient forum to the
            maintenance of such action or proceeding.  ADT Limited hereby
            irrevocably appoints Kay, Collyer & Boose (the "Process Agent"),
            with an office on the date hereof at 1 Dag Hammarskjold Plaza, New
            York, New York, United States (Attention:  Eli Schoenfield), as
            its agent to receive on behalf of ADT Limited and its property
            service of copies of the summons and complaint and any other
            process which may be served in any such action or proceeding.  Such
            service may be made by mailing or delivering a copy of such
            process to ADT Limited in care of the Process Agent at the Process
            Agent's above address, and ADT Limited hereby irrevocably
            authorizes and directs the Process Agent to accept such service on
            its behalf.  As an alternative method of service, ADT Limited also
            irrevocably consents to the service of any and all process in any
            such action or proceeding by the mailing of copies of such process
            to ADT Limited at its address specified on the signature page
            hereof.  ADT Limited hereby agrees that in the event the Process
            Agent is no longer resident in New York, New York, it shall
            appoint a successor Process Agent resident in New York, New York
            reasonably acceptable to the Agent, which successor Process Agent
            shall thereafter be the Process Agent hereunder.  ADT Limited
            agrees that a final judgment in any such action or proceeding
            shall be conclusive and may be enforced in other jurisdictions by
            suit on the judgment or in any other manner provided by law.

                  (b)  Nothing in this Section shall affect the right of any
            Lender Party or any holder of any Note to serve legal process in
            any other manner permitted by law or affect the right of any
            Lender Party or any holder of any Note to bring any action or
            proceeding against ADT Limited or any of its properties in the
            courts of any other jurisdictions.

                  (c)  To the extent that ADT Limited has or hereafter may
            acquire any immunity from jurisdiction of any court or from any
            legal process (whether through service or notice, attachment prior
            to judgment, attachment in aid of execution, execution or
            otherwise) with respect to itself or its property, ADT Limited
            hereby irrevocably waives, to the fullest extent permitted under
            applicable law, such immunity in respect of its obligations under
            this Guaranty.


                                  ARTICLE III

                        REPRESENTATIONS AND WARRANTIES

            ADT Limited hereby represents and warrants unto each Lender Party
as set forth in this Article III.

            SECTION 3.1.  Organization, etc.  Each of ADT Limited and its
Subsidiaries that is an Obligor or a Material Related Party is a company or
corporation, as the case may be, duly organized and validly existing and, to
the extent applicable, in good standing under the laws of the jurisdiction of
its organization, is duly qualified to do business and is, to the extent
applicable, in good standing as a foreign corporation in each jurisdiction
where the nature of its business requires such qualification and where the
failure to so qualify or be in good standing would reasonably be expected to
have a material adverse effect on the business, results of operations,
financial condition or prospects of ADT Limited and its Subsidiaries taken as
a whole.  Each of ADT Limited and its Subsidiaries that is an Obligor or a
Material Related Party has full power and authority and holds all requisite
governmental licenses, permits and other approvals (i) to own and hold under
lease its property and to conduct its business substantially as currently
conducted by it, except where failure to hold such licenses, permits and other
approvals would not reasonably be expected to have a material adverse effect
on the business, results of operations, financial condition or prospects of
ADT Limited and its Subsidiaries taken as a whole and (ii) to enter into and
perform its obligations under each Loan Document, if any, to which it is a
party.

            SECTION 3.2.  Due Authorization, Non-Contravention, etc.  The
execution, delivery and performance by ADT Limited of this Guaranty and each
other Loan Document executed or to be executed by it, and the execution,
delivery and performance by each other Obligor of each Loan Document executed
or to be executed by it, are within ADT Limited's and each such Obligor's
corporate powers, have been duly authorized by all necessary corporate action,
and do not

                  (a)  contravene ADT Limited's or any such Obligor's Organic
            Documents;

                  (b)  contravene any contractual restriction, law or
            governmental regulation or court decree or order binding on or
            affecting ADT Limited or any such Obligor (including the Companies
            Act 1981 of Bermuda) in any manner that could reasonably be
            expected (i) to have a material adverse effect on the business,
            results of operations, financial condition or prospects of ADT
            Limited and its Subsidiaries taken as a whole, (ii) to impair the
            ability of any Lender, Issuer or Agent to enforce the Obligations
            or (iii) to subject any Lender, Issuer or Agent to any liability;
            or

                  (c)  result in, or require the creation or imposition of,
            any Lien on any of ADT Limited's or any Obligor's properties.

            SECTION 3.3.  Government Approval, Regulation, etc.  No
authorization or approval or other action by, and no notice to or filing with,
any governmental authority or regulatory body or other Person is required for
the due execution, delivery or performance by ADT Limited or any other Obligor
of this Guaranty or any other Loan Document to which it is a party.  Neither
ADT Limited nor any other Obligor is an "investment company" within the
meaning of the Investment Company Act of 1940, as amended, or a "holding
company", or a "subsidiary company" of a "holding company", or an "affiliate"
of a "holding company" or of a "subsidiary company" of a "holding company",
within the meaning of the Public Utility Holding Company Act of 1935, as
amended.

            SECTION 3.4.  Validity, etc.  This Guaranty constitutes, and each
other Loan Document executed by ADT Limited will, on the due execution and
delivery thereof, constitute, the legal, valid and binding obligations of ADT
Limited enforceable in accordance with their respective terms, subject to
applicable bankruptcy, insolvency, reorganization, moratorium or similar laws
from time to time in effect affecting creditors' rights generally and to
general principles of equity; and each Loan Document executed pursuant hereto
by each other Obligor will, on the due execution and delivery thereof by such
Obligor, be the legal, valid and binding obligation of such Obligor enforceable
in accordance with its terms, subject to applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws from time to time in effect
affecting creditors' rights generally and to general principles of equity.

            SECTION 3.5.  Financial Information.  The financial statements set
forth in the 10-K of ADT Limited for the 1995 Fiscal Year and in the 10-Qs of
ADT Limited for the first three Fiscal Quarters of the 1996 Fiscal Year and
all financial statements of ADT Limited and its Subsidiaries furnished to the
Agent and the Lenders pursuant to clauses (a) and (d) of Section 8.1.1 of the
Credit Agreement have, in each case, been prepared in accordance with GAAP
consistently applied, and present fairly the consolidated financial condition
of the corporations covered thereby, as at the dates thereof, and the results
of their operations for the periods then ended.

            SECTION 3.6.  No Material Adverse Change.  Since December 31,
1995, there has been no material adverse change in the business, results of
operations, financial condition or prospects of ADT Limited and its
Subsidiaries taken as a whole.

            SECTION 3.7.  Litigation, Labor Controversies, etc.  There is no
pending or, to the knowledge of ADT Limited, threatened litigation, action,
proceeding, or labor controversy affecting ADT Limited or any of its
Subsidiaries, or any of their respective properties, businesses, assets or
revenues, which could reasonably be expected to materially adversely affect
the financial condition, results of operations, business or prospects of ADT
Limited and its Subsidiaries, taken as a whole (provided that no representation
is being made with respect to the effect on such financial condition, results
of operations, business or prospects of any litigation, action or proceeding
described in the first two paragraphs under the caption "Certain Litigation
Against the Company" in the Preliminary Proxy Statement of ADT Limited filed
with the Securities and Exchange Commission on January 8, 1997, provided to
the Agent prior to the date hereof, including any amendment to the complaint
referred to therein provided to the Agent prior to the Closing Date relating
to the scheduling of the special meeting of ADT Limited's shareholders
referred to in any such amendment), or which purports to affect the legality,
validity or enforceability of this Guaranty, or any other Loan Document,
except as disclosed in Item 3.7 ("Litigation") of the Disclosure Schedule.

            SECTION 3.8.  Subsidiaries.  ADT Limited has no Subsidiaries,
except those Subsidiaries

                  (a)  which are identified in Item 3.8 ("Existing
            Subsidiaries") of the Disclosure Schedule; or

                  (b)  which are permitted to have been created or acquired in
            accordance with Section 4.2.5 or 4.2.9.

Without limiting any term or provision hereof, to the extent any Person
becomes a Subsidiary of ADT Limited in accordance with (and not in
contravention of) any term or provision hereof or of any other Loan Document,
ADT Limited may supplement such Item 3.8 of the Disclosure Schedule to include
such new Subsidiary by delivering a certificate, signed by an Authorized
Officer, certifying (i) as to the name and place of organization of such new
Subsidiary, (ii) as to the method by which such new Subsidiary was created and
(iii) that such new Subsidiary was created without contravening any term or
provision hereof or of any other Loan Document.

            SECTION 3.9.  Ownership of Properties.  ADT Limited and each of
its Subsidiaries owns good and marketable title to, or valid leases of, all of
its properties and assets necessary to conduct its business substantially as
currently conducted by it.

            SECTION 3.10.  Taxes.  ADT Limited and each of its Subsidiaries,
and each other Obligor, has filed all material tax returns and reports required
by law to have been filed by it and has paid all material taxes and
governmental charges thereby shown to be owing, except any such taxes or
charges which are being diligently contested in good faith by appropriate
proceedings and for which adequate reserves in accordance with GAAP shall have
been set aside on its books.

            SECTION 3.11.  Pension and Welfare Plans.  During the
twelve-consecutive-month period prior to the date of the execution and
delivery of the Credit Agreement and prior to the date of any Credit Extension
thereunder, no steps have been taken to terminate any Pension Plan which
termination could result in the incurrence by ADT Limited or any member of the
Controlled Group of any material liability, and no contribution failure has
occurred with respect to any Pension Plan sufficient to give rise to a Lien
under section 302(f) of ERISA.  No condition exists or event or transaction
has occurred with respect to any Pension Plan which might result in the
incurrence by ADT Limited or any member of the Controlled Group of any
material liability, fine or penalty.  Except as disclosed in Item 3.11
("Employee Benefit Plans") of the Disclosure Schedule, neither ADT Limited nor
any member of the Controlled Group has any material contingent liability with
respect to any post-retirement benefit under a Welfare Plan, other than
liability for continuation coverage described in Part 6 of Title I of ERISA.

            SECTION 3.12.  Environmental Warranties.  Except as set forth in
Item 3.12 ("Environmental Matters") of the Disclosure Schedule,

                  (a)  all facilities and property (including underlying
            groundwater) owned or leased by ADT Limited or any of its
            Subsidiaries have been, and continue to be, owned or leased by ADT
            Limited and its Subsidiaries in material compliance with all
            Environmental Laws;

                  (b)  there have been no past, and there are no pending or
            threatened

                        (i)  claims, complaints, notices or requests for
                  information received by ADT Limited or any of its
                  Subsidiaries with respect to any alleged violation of any
                  Environmental Law, which could reasonably be expected to
                  have a material adverse effect on the business, results of
                  operations, financial condition or prospects of ADT Limited
                  and its Subsidiaries or the Borrower and its Subsidiaries, or

                        (ii)  complaints, notices or inquiries to ADT Limited
                  or any of its Subsidiaries regarding potential liability
                  under any Environmental Law, which could reasonably be
                  expected to have a material adverse effect on the business,
                  results of operations, financial condition or prospects of
                  ADT Limited and its Subsidiaries or the Borrower and its
                  Subsidiaries;

                  (c)  there have been no Releases of Hazardous Materials at,
            on or under any property now or previously owned or leased by ADT
            Limited or any of its Subsidiaries that, singly or in the
            aggregate, have, or may reasonably be expected to have, a material
            adverse effect on the business, results of operations, financial
            condition or prospects of ADT Limited and its Subsidiaries or the
            Borrower and its Subsidiaries;

                  (d)  ADT Limited and its Subsidiaries have been issued and
            are in compliance with all permits, certificates, approvals,
            licenses and other authorizations relating to environmental
            matters and necessary for their businesses, except where the
            failure to have been issued any such permit, certificate,
            approval, license or other authorization or to have complied with
            any of the foregoing would not, singly or in the aggregate,
            reasonably be expected to have a material adverse effect on the
            business, results of operations, financial condition or prospects
            of ADT Limited and its Subsidiaries or the Borrower and its
            Subsidiaries;

                  (e)  no property now or previously owned or leased by ADT
            Limited or any of its Subsidiaries is listed or proposed for
            listing (with respect to owned property only) on the National
            Priorities List pursuant to CERCLA, on the CERCLIS or on any
            similar state list of sites requiring investigation or clean-up
            that is reasonably likely to lead to material claims against ADT

            CERCLA;

            reasonably be expected to have, a material adverse effect on the
            business, results of operations, financial condition or prospects

            Subsidiaries;

            for any remedial work, damage to natural resources or personal
            injury, including claims under CERCLA;

                  (h)  there are no polychlorinated biphenyls or friable
            asbestos present at any property now or previously owned or leased
            by ADT Limited or any Subsidiary of ADT Limited that, singly or in
            the aggregate, have, or may reasonably be expected to have, a
            material adverse effect on the business, results of operations,
            financial condition or prospects of ADT Limited and its
            Subsidiaries or the Borrower and its Subsidiaries; and

                  (i)  no conditions exist at, on or under any property now

            Subsidiaries after due inquiry, any property previously owned or
            leased) by ADT Limited or any Subsidiary of ADT Limited which

            business, results of operations, financial condition or prospects
            of ADT Limited and its Subsidiaries or the Borrower and its
            Subsidiaries.

Subsidiary of ADT Limited is in violation of, or in default under, any term or
provision of its Organic Documents or any contract, agreement, indenture,

of any such Person, to any Agent or any Lender will be, true, complete and
accurate in every material respect on the date as of which such information is
dated or certified and as of the date of execution and delivery of the Credit
Agreement by such Agent and such Lender (it being acknowledged that, with
respect to any specific financial statement included in such information, such
financial statement shall have been true, complete and accurate in every
material respect on the date or for the period expressly set forth therein and
not necessarily on any other date or for any other period), and such

            maintenance and preservation by ADT Limited and each of its
            Subsidiaries that is an Obligor or a Material Related Party of its
            corporate existence and qualification as a foreign corporation in
            each jurisdiction where the nature of its business or the location
            of its assets requires it to be so qualified, except to the extent
            the failure to maintain and preserve its corporate existence or to
            be so qualified could not reasonably be expected to have a
            material adverse effect on the business, results of operations,
            financial condition or prospects of ADT Limited and its
            Subsidiaries (it being acknowledged that the failure of ADT
            Limited or the Borrower to maintain and preserve its corporate
            existence (except as permitted under Section 4.2.9) shall be
            deemed to have such a material adverse effect); and

                  (b)  the payment, before the same become delinquent, of all
            material taxes, assessments and governmental charges imposed upon
            it or upon its property except to the extent being diligently
            contested in good faith by appropriate proceedings and for which

            aside on its books.

            SECTION 4.1.2.  Maintenance of Properties.  ADT Limited will, and
will cause each of its Subsidiaries to, maintain, preserve, protect and keep
its material properties in good repair, working order and condition, and make
necessary and proper repairs, renewals and replacements so that its business
carried on in connection therewith may be properly conducted at all times
unless ADT Limited determines in good faith that the continued maintenance of
any of its properties is no longer economically desirable.

            SECTION 4.1.3.  Insurance.  ADT Limited will, and will cause each
of its Subsidiaries to, maintain or cause to be maintained with responsible
insurance companies insurance with respect to its properties and business
(including business interruption insurance) against such casualties and

Limited and its Subsidiaries in accordance with this Section.

            SECTION 4.1.4.  Books and Records.  ADT Limited will, and will
cause each of its Subsidiaries to, keep books and records which accurately
reflect all of its business affairs and transactions and permit the Agent or
any of its representatives, at reasonable times and intervals (but not more

occurred and be continuing (in which case, and during such period, each Lender
shall have the rights of the Agent under this Section)) to visit all of its
offices, to discuss its financial matters with its officers and independent
public accountant (provided a representative of ADT Limited or such Subsidiary
is given prior notice of, and the opportunity to be present during, such
discussion) and, subject to appropriate agreements of confidentiality and to
any restrictions imposed under applicable law (including regulations
promulgated by the  United States Department of Defense), to examine any of
its books or other corporate records.  ADT Limited shall pay any fees of such
independent public accountant incurred in connection with the Agent's or any
Lender's exercise of its rights pursuant to this Section.  In addition, ADT
Limited shall pay the reasonable out-of-pocket expenses arising from the
Agent's visit to the offices of ADT Limited or any of its Subsidiaries in
connection with the exercise of its rights pursuant to this Section to the
extent of one such visit per Fiscal Year.

will cause each of its Subsidiaries to,

                  (a)  use and operate all of its facilities and properties in
            material compliance with all Environmental Laws, apply for and
            keep all necessary permits, approvals, certificates, licenses and
            other authorizations relating to environmental matters in effect
            where the failure to so keep in effect could reasonably be
            expected to have a material adverse effect on the business,
            results of operations, financial condition or prospects of ADT
            Limited and its Subsidiaries or the Borrower and its Subsidiaries
            and remain in material compliance therewith, and handle all

                  (b)  immediately notify the Agent and provide copies upon
            receipt of all written claims, complaints, notices or inquiries
            relating to the condition of its facilities and properties or
            compliance with Environmental Laws, which claims or other alleged
            conditions could reasonably be expected to have a material adverse
            effect on the business, results of operations, financial condition
            or prospects of ADT Limited and its Subsidiaries or the Borrower
            and its Subsidiaries; and

                  (c)  provide such information and certifications which the
            Agent may reasonably request from time to time to evidence
            compliance with this Section 4.1.5.

            SECTION 4.1.6.  Guaranty Supplements.  ADT Limited will cause each
Material Subsidiary and each Subsidiary subject to a Senior Note Guarantee to
be a Guarantor.  In furtherance of the foregoing, ADT Limited will, in the
event any Person becomes a Material Subsidiary, notify the Agent of such event
or condition and will cause such new Material Subsidiary to execute and
deliver to the Agent as soon as practicable (but in no event later than thirty
days after the occurrence of such event or condition) a Subsidiary Guarantor
Guaranty Supplement, together with such certificates and legal opinions as the
Agent may reasonably request.

            SECTION 4.1.7.  Maintenance of Adequate Guarantees.  If at any time
the Subsidiary Guarantors subject to the obligations of the Subsidiary
Guarantor Guaranty do not account on a consolidated basis for at least 90% of
the consolidated gross revenues of the Borrower and its Subsidiaries and at
least 90% of the consolidated gross assets of the Borrower and its Subsidiaries
(collectively, the "90% Test"), as reflected in the consolidated statement of
income and consolidated balance sheet most recently delivered, or required to
be delivered, pursuant to Section 8.1.1(a) or 8.1.1(d) of the Credit Agreement,
ADT Limited will cause such Non-Guarantors organized under the laws of the
United States (or any state thereof or the District of Columbia) as are
necessary to meet the 90% Test to execute and deliver to the Agent as soon as
practicable (but in no event later than thirty days after the occurrence of
such event or condition) a Subsidiary Guarantor Guaranty Supplement, together
with such certificates and legal opinions as the Agent may reasonably request.

            SECTION 4.2.  Negative Covenants.  ADT Limited covenants and
agrees that, until the Covenant Termination Date, ADT Limited will not,
without the prior written consent of the Required Lenders, do anything
prohibited in this Section.

except for those activities conducted in respect of the Core Businesses and the
businesses identified in Item 4.2.1 ("Permitted Existing Business Activities")
of the Disclosure Schedule, and such activities as may be incidental or related
thereto; provided, however, that ADT Limited will not be in default in the
observance of this Section 4.2.1 if, as part of the acquisition of a Core
Business, ADT Limited or its applicable Subsidiary acquires a business or
assets that would not constitute, or be included in, a Core Business, so long
as (i) the primary purpose of such acquisition was the acquisition of such Core
Business, which acquisition could not have been consummated on as commercially

            with the terms of the Articles of Incorporation of ADT Finance
            Inc. as in effect on the Existing Credit Facility Effective Date)
            shall be permitted if an Event of Default (including a default in
            the observance by the Borrower of its obligations under clause (a)
            of Section 8.2.3 of the Credit Agreement) shall have occurred and
            be continuing or would occur upon giving effect to such Restricted
            Distribution; and

                  (y)  no Restricted Distribution otherwise permitted pursuant
            to this Section 4.2.6(a) shall be permitted if such Restricted
            Distribution would, pursuant to the terms of the Senior Note
            Indenture, decrease the Restricted Payment Basket Amount to an
            amount which is less than the excess of (1) the sum of (A) the
            aggregate amount expended on Permitted Business Acquisitions
            (other than the ASH Transaction to the extent the aggregate
            consideration therefor did not exceed $425,000,000) after the
            Existing Credit Facility Effective Date in excess of the
            applicable Annual Limits (or, during the effectiveness of the
            Existing Credit Facility, the applicable Annual Limits (as defined
            under the Existing Credit Facility)) and (B) the aggregate amount
            of Capital Expenditures made after the Existing Credit Facility
            Effective Date with the cash proceeds referred to in clause (a) of
            the definition of Equity Proceeds Amount and designated as such
            pursuant to the Compliance Certificate (including any compliance
            certificate delivered under the Existing Credit Facility)
            delivered in connection with the Fiscal Quarter in which such
            Capital Expenditures were paid over (2) the portion (if any) of
            such sum which resulted in a decrease of the Restricted Payment
            Basket Amount.

            (b)  ADT Limited will not, and will not permit any of its
Subsidiaries to, directly or indirectly,

                  (i)  declare or pay any dividend on, or make any
            distribution to holders of, any shares of Capital Stock of the
            Borrower (other than (A) dividends or distributions payable in
            shares of Capital Stock of the Borrower or in rights, warrants or
            options to purchase such Capital Stock, but excluding dividends or
            distributions payable in Redeemable Capital Stock or in options,
            warrants or other rights to purchase Redeemable Capital Stock,
            provided that dividends on Redeemable Capital Stock may be paid in
            shares of such Redeemable Capital Stock and (B) the dividend of
            the Dividended Note), or

                  (ii)  purchase, redeem, retire or otherwise acquire for
            value, or make any payment on account of the purchase, redemption,
            retirement or other acquisition for value of, any Capital Stock of
            the Borrower or any warrants, rights or options to purchase or
            acquire any such Capital Stock

(such payments or any other actions described in (but not excluded from) the
foregoing clauses (i) and (ii) being herein referred to as "Restricted Borrower
Distributions"), unless the amount of such Restricted Borrower Distribution
(which amount, in the case of a Restricted Borrower Distribution to be made
in property, shall equal the Fair Market Value thereof (as determined, in the
case of any property with an aggregate value in excess of $15,000,000, in good
faith by the Board of Directors of the Borrower, whose determination shall be
evidenced by a certified written resolution of such Board)), when added to the
aggregate amount of all such Restricted Borrower Distributions declared since
the Existing Credit Facility Effective Date, would not exceed 50% of the
aggregate Net Income of the Borrower accrued on a cumulative basis during the
period (taken as one accounting period) from the Existing Credit Facility
Effective Date to the last day of the most recently completed Fiscal Quarter
with respect to which, pursuant to Section 8.1.1(a) or 8.1.1(d) of the Credit
Agreement (or Section 8.1.1(d) of the Existing Credit Facility), financial
statements have been delivered to the Agent on or prior to the date of the
proposed Restricted Borrower Distribution; provided, however, that no
Restricted Borrower Distribution otherwise permitted pursuant to this Section
4.2.6(b) shall be permitted if an Event of Default (including a default in the
observance by the Borrower of its obligations under clause (a) of Section
8.2.3 of the Credit Agreement) shall have occurred and be continuing or would
occur upon giving effect to such Restricted Borrower Distribution.

            (c)  ADT Limited will not, and will not permit any of its
Subsidiaries to, directly or indirectly,

                  (i)  make any payment of interest on the Senior Notes or any
            Subordinated Debt (other than Subordinated Debt originally issued
            to ADT Limited or a Wholly Owned Subsidiary of ADT Limited (or
            otherwise acquired by ADT Limited or such Wholly-Owned Subsidiary,
            to the extent that the consideration paid by ADT Limited or a
            Wholly-Owned Subsidiary resulted in a decrease of the Restricted
            Payment Basket Amount) and held by ADT Limited or a Wholly Owned
            Subsidiary of ADT Limited) on any day other than the date such
            payment is required to be made as set forth in the Senior Notes,
            the Senior Note Indenture, the Senior Subordinated Note Indenture,
            the LYONs, the LYONs Indenture or the other documents and
            instruments memorializing such Subordinated Debt, or which, in the
            case of any Subordinated Debt (including Subordinated Debt held by
            ADT Limited or a Wholly Owned Subsidiary of ADT Limited), would
            violate the subordination provisions thereof; or

                  (ii)  make any payment or prepayment of principal of, or
            redeem, purchase, repurchase or defease, the Senior Notes or any
            Subordinated Debt (other than Subordinated Debt originally issued
            to ADT Limited or a Wholly Owned Subsidiary of ADT Limited (or
            otherwise acquired by ADT Limited or such Wholly-Owned Subsidiary,
            to the extent that the consideration paid by ADT Limited or such
            Wholly-Owned Subsidiary resulted in a decrease of the Restricted
            Payment Basket Amount) and held by ADT Limited or a Wholly Owned
            Subsidiary of ADT Limited, except, prior to the occurrence of a
            Permitted Auction Business Sale, Subordinated Debt in respect of
            the Dividended Note) on any day other than the date any such
            payment, prepayment, redemption or repurchase is required to be
            made as set forth in Sections 1010 and 1016 of the Senior Note
            Indenture, Sections 1010 and 1016 of the Senior Subordinated Note
            Indenture, Section 3.09 of the LYONs Indenture or in the other
            documents and instruments memorializing the Senior Notes or such
            Subordinated Debt, or which, in the case of any Subordinated Debt
            (including Subordinated Debt held by ADT Limited or a Wholly Owned
            Subsidiary of ADT Limited), would violate the subordination
            provisions thereof; provided, however, that ADT Limited and its
            Subsidiaries may, to the extent the subordination provisions of
            the Senior Subordinated Note Indenture, the LYONs Indenture or any
            other document or instrument memorializing Subordinated Debt would
            not be violated thereby, make any payment or prepayment of
            principal of, or redeem or repurchase, the Senior Notes or any
            Subordinated Debt if permitted by the terms of the Senior Note
            Indenture; provided further, however, that no payment, prepayment,
            redemption or repurchase otherwise permitted pursuant to the
            immediately preceding proviso shall be permitted if (x) an Event of
            Default shall have occurred and be continuing or would occur upon
            giving effect to such payment, prepayment, redemption or repurchase
            or (y) such payment, prepayment, redemption or repurchase would,
            pursuant to the terms of the Senior Note Indenture, decrease the
            Restricted Payment Basket Amount to an amount which is less than
            the excess of (1) the sum of (A) the aggregate amount expended on
            Permitted Business Acquisitions (other than the ASH Transaction to
            the extent the aggregate consideration therefor did not exceed
            $425,000,000) after the Existing Credit Facility Effective Date in
            excess of the applicable Annual Limits (or, during the
            effectiveness of the Existing Credit Facility, the applicable
            Annual Limits (as defined under the Existing Credit Facility)) and
            (B) the aggregate amount of Capital Expenditures made after the
            Existing Credit Facility Effective Date with the cash proceeds
            referred to in clause (a) of the definition of Equity Proceeds
            Amount and designated as such pursuant to the Compliance
            Certificate (including any compliance certificate delivered under
            the Existing Credit Facility) delivered in connection with the
            Fiscal Quarter in which such Capital Expenditures were paid over
            (2) the portion (if any) of such aggregate amount which resulted
            in a decrease of the Restricted Payment Basket Amount.

            SECTION 4.2.7.  Capital Expenditures, etc.  ADT Limited will not,
and will not permit any of its Subsidiaries to, make Capital Expenditures,
except (i) Capital Expenditures in connection with conducting the Core
Businesses and (ii) Capital Expenditures incurred in respect of Business
Acquisitions permitted under Sections 4.2.5 and 4.2.9; provided, however, that
no Capitalized Lease Liabilities otherwise permitted to be incurred pursuant
to this Section shall be permitted to be incurred if the aggregate amount of
all such Capitalized Lease Liabilities incurred during any Fiscal Year would
exceed $30,000,000.

            SECTION 4.2.8.  [Intentionally Omitted.]

            SECTION 4.2.9.  Consolidation, Merger, etc.  ADT Limited will not,
and will not permit any of its Subsidiaries to, liquidate or dissolve, or
amalgamate or consolidate with, or merge into or with, any other Person, or
otherwise enter into or consummate any Business Acquisition not constituting
an Investment, except

                  (a)  any Subsidiary of ADT Limited that is a direct or
            indirect parent of the Borrower may liquidate or dissolve
            voluntarily into, and may amalgamate or consolidate with or merge
            into, ADT Limited or any Wholly Owned Subsidiary of ADT Limited
            that is an indirect parent of the Borrower, and any assets or
            Capital Stock of any Subsidiary of ADT Limited that is an indirect

                              GUARANTY PROVISIONS

            SECTION 2.1.  Guaranty.  Each Subsidiary Guarantor hereby
absolutely, unconditionally and irrevocably, jointly and severally,

                  (a)  guarantees the full and punctual payment when due,
            whether at stated maturity, by required prepayment, declaration,
            acceleration, demand or otherwise, of all Obligations of the
            Borrower and each other Obligor now or hereafter existing, whether
            for principal, interest, Reimbursement Obligations, fees, expenses
            or otherwise (including all such amounts which would become due
            but for the operation of the automatic stay under Section 362(a)
            of the United States Bankruptcy Code, 11 U.S.C. Section 362(a),
            and the operation of Sections 502(b) and 506(b) of the United
            States Bankruptcy Code, 11 U.S.C. Section 502(b) and Section
            506(b)); and

                  (b)  indemnifies and holds harmless each Lender Party and
            each holder of a Note for any and all costs and expenses (including
            reasonable attorney's fees and expenses) incurred by such Lender
            Party or such holder, as the case may be, in enforcing any rights
            under this Guaranty;

provided, however, that each Subsidiary Guarantor shall be liable under this
Guaranty for the maximum amount of such liability that can be hereby incurred
without rendering this Guaranty, as it relates to such Subsidiary Guarantor,
voidable under applicable law relating to fraudulent conveyance or fraudulent
transfer, and not for any greater amount.  This Guaranty constitutes a
guaranty of payment when due and not of collection, and each Subsidiary
Guarantor specifically agrees that it shall not be necessary or required that
any Lender Party or any holder of any Note exercise any right, assert any
claim or demand or enforce any remedy whatsoever against the Borrower or any
other Obligor (or any other Person) before or as a condition to the
obligations of such Subsidiary Guarantor hereunder.

            SECTION 2.2.  Guaranty Absolute, etc.  This Guaranty shall in all
respects be a continuing, absolute, unconditional and irrevocable guaranty of
payment, and shall remain in full force and effect until all Obligations of the
Borrower and each other Obligor have been paid in full, all obligations of each
Subsidiary Guarantor hereunder shall have been paid in full and all
Commitments shall have terminated.  Each Subsidiary Guarantor guarantees that
the Obligations of the Borrower and each other Obligor and their respective
Subsidiaries will be paid strictly in accordance with the terms of the Credit
Agreement and each other Loan Document under which they arise, without regard
(to the fullest extent permitted under applicable law) to any law, regulation
or order now or hereafter in effect in any jurisdiction affecting any of such
terms or the rights of any Lender Party or any holder of any Note with respect
thereto (and each Subsidiary Guarantor hereby waives to the fullest extent it
may do so any right or rights it may have under any such law, regulation or
order).  Without limiting the generality of the foregoing, the liability of
each Subsidiary Guarantor under this Guaranty shall be absolute, unconditional
and irrevocable irrespective of:

                  (a)  any lack of genuineness, validity, legality or
            enforceability of the Credit Agreement or any other Loan Document
            (other than, in respect of such Subsidiary Guarantor, this
            Guaranty) or of any of the Obligations (other than the Obligations
            of such Subsidiary Guarantor hereunder);

                  (b)  the failure of any Lender Party or any holder of any
            Note

                        (i)  to assert any claim or demand or to enforce any
                  right or remedy against the Borrower, any other Obligor or
                  any other Person (including any other Subsidiary Guarantor)
                  under the provisions of the Credit Agreement or any other
                  Loan Document or otherwise, or

                        (ii)  to exercise any right or remedy against any other
                  guarantor (including any other Subsidiary Guarantor) of, or
                  collateral securing, any Obligations of the Borrower or any
                  other Obligor;

                  (c)  any change in the time, manner or place of payment of,
            or in any other term of, all or any of the Obligations of the
            Borrower or any other Obligor (other than such Subsidiary
            Guarantor), or any other extension, compromise or renewal of any
            Obligation of the Borrower or any other Obligor (other than such
            Subsidiary Guarantor);

                  (d)  any reduction, limitation, impairment or termination of
            the Obligations of the Borrower or any other Obligor (other than
            such Subsidiary Guarantor) for any reason, including any claim of
            waiver, release, surrender, alteration or compromise, and shall
            not be subject to (and each Subsidiary Guarantor hereby waives any
            right to or claim of) any defense or setoff, counterclaim,
            recoupment or termination whatsoever by reason of the invalidity,
            illegality, nongenuineness, irregularity, compromise,
            unenforceability of, or any other event or occurrence affecting,
            the Obligations of the Borrower, any other Obligor (other than
            such Subsidiary Guarantor) or otherwise;

                  (e)  any amendment to, rescission, waiver, or other
            modification of, or any consent to departure from, any of the
            terms of the Credit Agreement or any other Loan Document (other
            than, in respect of such Subsidiary Guarantor, this Guaranty);

                  (f)  any addition, exchange, release, surrender or
            non-perfection of any collateral, or any amendment to or waiver or
            release of or addition to, or consent to departure from, any other
            guaranty (including the ADT Limited Guaranty), held by any Lender
            Party or any holder of any Note securing any of the Obligations of
            the Borrower or any other Obligor; or

                  (g)  any other circumstances which might otherwise
            constitute a defense available to, or a legal or equitable
            discharge of, the Borrower, any other Obligor, any surety or any
            other guarantor (or any other Guarantor).

            SECTION 2.3.  Stay of Acceleration, Reinstatement, etc.  Each
Subsidiary Guarantor agrees that, if acceleration of the time for payment of
any amount payable by the Borrower under the Credit Agreement, the Notes or
any other Loan Document or of compliance by the Borrower with its obligations
under Section 4.7 of the Credit Agreement is, in either case, stayed upon the
occurrence with respect to the Borrower of any Event of Default described in
clause (b) or (d) of Section 9.1.9 of the Credit Agreement, all such amounts
and obligations otherwise subject to acceleration or compliance under the
terms of the Credit Agreement shall nonetheless be payable and performed by
such Subsidiary Guarantor hereunder forthwith on demand by the Agent made at
the request of the requisite proportion of the Lenders specified in Section
9.3 of the Credit Agreement.  Each Subsidiary Guarantor agrees that this
Guaranty shall continue to be effective or be reinstated, as the case may be,
if at any time any payment (in whole or in part) of any of the Obligations is
rescinded or must otherwise be restored by any Lender Party or any holder of
any Note, upon the insolvency, bankruptcy or reorganization of the Borrower,
any other Obligor (other than such Subsidiary Guarantor) or otherwise, all as
though such payment had not been made.

            SECTION 2.4.  Waiver, etc.  Each Subsidiary Guarantor hereby
waives promptness, diligence, notice of acceptance and any other notice with
respect to any of the Obligations of the Borrower or any other Obligor and this
Guaranty and any requirement that the Agent, any other Lender Party or any
holder of any Note protect, secure, perfect or insure any security interest or
Lien, or any property subject thereto, or exhaust any right or take any action
against the Borrower, any other Obligor or any other Person (including any
other guarantor and any other Guarantor) or entity or any collateral securing
the Obligations of the Borrower or any other Obligor, as the case may be.

            SECTION 2.5.  Subrogation.  Each Subsidiary Guarantor hereby
agrees that it will not exercise any rights which it may now or hereafter
acquire against the Borrower or any other Obligor that arise from the
existence, payment, performance or enforcement of such Subsidiary Guarantor's
obligations under this Guaranty or any other Loan Document, including any
right of subrogation, reimbursement, exoneration, or indemnification, any
right to participate in any claim or remedy of the Lender Parties against the
Borrower or any other Obligor or any collateral which the Agent now has or
hereafter acquires, whether or not such claim, remedy or right arises in
equity, or under contract, statute or common law, including the right to take
or receive from the Borrower or any other Obligor, directly or indirectly, in
cash or other property or by set-off or in any manner, payment or security on
account of such claim or other rights, until the Obligations have been paid in
full in cash and the Commitments have been terminated.  If any amount shall be
paid to such Subsidiary Guarantor in violation of the preceding sentence and
the Obligations shall not have been paid in cash in full and the Commitments
have not been terminated, such amount shall be deemed to have been paid to
such Subsidiary Guarantor for the benefit of, and held in trust for, the
Lender Parties, and shall forthwith be paid to the Lender Parties to be
credited and applied upon the Obligations, whether matured or unmatured.  Each
Subsidiary Guarantor acknowledges that it will receive direct and indirect
benefits from the financing arrangements contemplated by the Credit Agreement
and that the agreement set forth in this Section is knowingly made in
contemplation of such benefits.

            SECTION 2.6.  Successors, Transferees and Assigns; Transfers of
Notes, etc.  This Guaranty shall:

                  (a)  be binding upon each Subsidiary Guarantor and its
            successors, transferees and assigns; and

                  (b)  inure to the benefit of and be enforceable by the Agent
            and each other Lender Party.

Without limiting the generality of clause (b), any Lender may assign or
otherwise transfer (in whole or in part) any Note or Loan held by it to any
other Person or entity, and such other Person or entity shall thereupon become
vested with all rights and benefits in respect thereof granted to such Lender
under any Loan Document (including this Guaranty) or otherwise, subject,
however, to the provisions of Section 11.11 and Article X of the Credit
Agreement.

            SECTION 2.7.  Payments Free and Clear of Taxes, etc.  Each
Subsidiary Guarantor hereby agrees that:

                  (a)  Any and all payments made by such Subsidiary Guarantor
            hereunder shall be made in accordance with Section 5.6 of the
            Credit Agreement free and clear of, and without deduction for, any
            and all present or future taxes, levies, imposts, deductions,
            charges or withholdings, and all liabilities with respect thereto,
            excluding, in the case of each Lender Party or any holder of a
            Note, taxes imposed on its net income and franchise taxes imposed
            on it (such non-excluded items being hereinafter referred to as
            "Taxes").  If any such Subsidiary Guarantor shall be required by
            law to deduct any Taxes from or in respect of any sum payable
            hereunder to any Lender Party or any holder of a Note

                        (i)  the sum payable shall be increased as may be
                  necessary so that after making all required deductions
                  (including deductions applicable to additional sums payable
                  under this Section) such Lender Party or such holder, as the
                  case may be, receives an amount equal to the sum it would
                  have received had no such deductions been made,

                        (ii)  such Subsidiary Guarantor shall make such
                  deductions, and

                        (iii)  such Subsidiary Guarantor shall pay the full
                  amount deducted to the relevant taxation authority or other
                  authority in accordance with applicable law.

                  (b)  Such Subsidiary Guarantor shall pay any present or
            future stamp or documentary taxes or any other excise or property
            taxes, charges or similar levies which arise from any payment made
            hereunder or from the execution, delivery or registration of, or
            otherwise with respect to, this Guaranty (hereinafter referred to
            as "Other Taxes").

                  (c)  Such Subsidiary Guarantor hereby indemnifies and holds
            harmless each Lender Party and each of holder of a Note for the
            full amount of Taxes or Other Taxes (including, without
            limitation, any Taxes or Other Taxes imposed by any jurisdiction
            on amounts payable under this Section) paid by such Lender Party
            or such holder, as the case may be, and any liability (including
            penalties, interest and expenses) arising therefrom or with
            respect thereto, whether or not such Taxes or Other Taxes were
            correctly or legally asserted.

                  (d)  Without prejudice to the survival of any other
            agreement of such Subsidiary Guarantor hereunder, the agreements
            and obligations of such Subsidiary Guarantor contained in this
            Section 2.7 shall survive the payment in full of the principal of
            and interest on the Loans.


                                  ARTICLE III

                        REPRESENTATIONS AND WARRANTIES

            SECTION 3.1.  Representations and Warranties.  Each Subsidiary
Guarantor hereby represents and warrants for itself unto each Lender Party as
to all matters contained in Article VII of the Credit Agreement and Article III
of the ADT Limited Guaranty, in each case insofar as applicable to such
Subsidiary Guarantor or such Subsidiary Guarantor's properties, together with
all related definitions and ancillary provisions, all of which are hereby
incorporated into this Section 3.1 as those specifically set forth herein.  In
addition, each Subsidiary Guarantor hereby represents and warrants for itself
unto each Lender Party as further set forth in this Article III.

            SECTION 3.1.1.  Organization, etc.  Such Subsidiary Guarantor and
each of its Subsidiaries is a corporation duly organized and validly existing
and in good standing under the laws of the State of its incorporation, is duly
qualified to do business and is in good standing as a foreign corporation in
each jurisdiction where the nature of its business or the location of its
assets requires such qualification and where the failure to so qualify or be
in good standing would reasonably be expected to have a material adverse
effect on the business, results of operations, financial condition or
prospects of the Borrower and its Subsidiaries taken as a whole.  Such
Subsidiary Guarantor and each of its Subsidiaries has full power and authority
and holds all requisite governmental licenses, permits and other approvals (i)
to own and hold under lease its property and to conduct its business
substantially as currently conducted by it, except where failure to hold such
licenses, permits and other approvals would not reasonably be expected to have
a material adverse effect on the business, results of operations, financial
condition or prospects of the Borrower and its Subsidiaries taken as a whole
and (ii) to enter into and perform its obligations under this Guaranty and
each other Loan Document to which it is a party.


            SECTION 3.1.2.  Due Authorization, Non-Contravention, etc.  The
execution, delivery and performance by such Subsidiary Guarantor of this
Guaranty and each other Loan Document executed or to be executed by it and
such Subsidiary Guarantor's participation in the consummation of the
Transaction are within such Subsidiary Guarantor's corporate powers, have been
duly authorized by all necessary corporate action, and do not

                  (a)  contravene such Subsidiary Guarantor's Organic
            Documents;

                  (b)  contravene any contractual restriction, law or
            governmental regulation or court decree or order binding on or
            affecting such Subsidiary Guarantor in any manner that could
            reasonably be expected (i) to have a material adverse effect on
            the business, results of operations, financial condition or
            prospects of the Borrower and its Subsidiaries taken as a whole,
            (ii) to impair the ability of any Lender, any Issuer or the Agent
            to enforce the Obligations or (iii) to subject any Lender, any
            Issuer or the Agent to any liability; or

                  (c)  result in, or require the creation or imposition of,
            any Lien on any of such Subsidiary Guarantor's properties.

            SECTION 3.1.3.  Government Approval, Regulation, etc.  No
authorization or approval or other action by, and no notice to or filing with,
any governmental authority or regulatory body or other Person is required for
the due execution, delivery or performance by such Subsidiary Guarantor of
this Guaranty or any other Loan Document to which it is a party.  No
Subsidiary Guarantor is an "investment company" within the meaning of the
Investment Company Act of 1940, as amended, or a "holding company", or a
"subsidiary company" of a "holding company", or an "affiliate" of a "holding
company" or of a "subsidiary company" of a "holding company", within the
meaning of the Public Utility Holding Company Act of 1935, as amended.

            SECTION 3.1.4.  Validity, etc.  This Guaranty constitutes, and each
other Loan Document executed by such Subsidiary Guarantor will, on the due

            SECTION 5.3.  Amendments, etc.  No amendment to or waiver of any
provision of this Guaranty, nor consent to any departure by any Subsidiary

waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given.

            SECTION 5.4.  Addresses for Notices to the Subsidiary Guarantor.
All notices and other communications hereunder to any Subsidiary Guarantor

thereof or the exercise of any other right.  The remedies herein provided are
cumulative and not exclusive of any remedies provided by law.

            SECTION 5.6.  Headings.  The various headings used in this Guaranty

the right to appropriate and apply to the payment of the obligations of any
Subsidiary Guarantor owing to it hereunder, whether or not then due, any and
all balances, credits, deposits, accounts or moneys of such Subsidiary
Guarantor then or thereafter maintained with such Lender Party or such holder;
provided, however, that any such appropriation and application shall be
subject to the provisions of Section 5.8 of the Credit Agreement.

            SECTION 5.8.  Severability.  Wherever possible, each provision of
this Guaranty shall be interpreted in such manner as to be effective and valid

STATE OF NEW YORK AND OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN
DISTRICT OF NEW YORK FOR THE PURPOSE OF ANY SUCH LITIGATION AS SET FORTH ABOVE

SUBSIDIARY GUARANTOR HEREBY EXPRESSLY AND IRREVOCABLY WAIVES, TO THE FULLEST

GUARANTOR ACKNOWLEDGES AND AGREES THAT IT HAS RECEIVED FULL AND SUFFICIENT
CONSIDERATION FOR THIS PROVISION (AND EACH OTHER PROVISION OF EACH OTHER LOAN

INDUCEMENT FOR THE LENDER PARTIES ENTERING INTO THE CREDIT AGREEMENT AND EACH
SUCH OTHER LOAN DOCUMENT.

            SECTION 5.13.     Additional Subsidiary Guarantors.  Upon
execution and delivery by the Agent and any other Person (each such Person
being an "Additional Subsidiary Guarantor") of an instrument in the form of

Additional Subsidiary Guarantor as a party to this Guaranty.

            THIS SUBSIDIARY GUARANTOR GUARANTY SUPPLEMENT (this "Supplement"),
dated as of _____________, 199_, to the Subsidiary Guarantor Guaranty, dated
as of January ___, 1997 (as amended or otherwise modified through the date

thereto by executing an agreement in substantially the form hereof (each an
"Additional Subsidiary Guarantor" and, together with each Person identified on
the signature pages of the Guaranty, the "Subsidiary Guarantors"), in favor of
The Bank of Nova Scotia ("Scotiabank"), as documentation agent (the
"Documentation Agent") for each of the Lender Parties (such capitalized term
and all other capitalized terms used in this Supplement without being defined
shall have the meaning provided for in the Subsidiary Guaranty).


                             W I T N E S S E T H:

            WHEREAS, pursuant to a Credit Agreement, dated as of January ___,
1997 (together with all amendments and other modifications, if any, from time
to time made thereto, the "Credit Agreement"), among ADT Operations, Inc., a
Delaware corporation (the "Borrower"), the financial institutions as are or
may become parties thereto (collectively, the "Lenders"), and The Bank of Nova
Scotia ("Scotiabank"), individually and as agent (the "Agent") for the
Lenders, the Lenders have extended Commitments to make Credit Extensions to or
on behalf of the Borrower;

            WHEREAS, it is in the best interests of the undersigned (the "New
Additional Subsidiary Guarantor") to execute this Supplement inasmuch as the
New Additional Subsidiary Guarantor will derive substantial direct and indirect
benefits from the Credit Extensions made by the Lenders pursuant to the Credit
Agreement; and

            WHEREAS, the New Additional Subsidiary Guarantor desires to become
an Additional Subsidiary Guarantor under the Subsidiary Guaranty pursuant to
Section 5.13 thereof;

            NOW, THEREFORE, for good and valuable consideration the receipt
of which is hereby acknowledged, the New Additional Subsidiary Guarantor
agrees, for the benefit of each Lender Party, as follows:

            SECTION 1.  Additional Subsidiary Guarantor.  In accordance with
Section 5.13 of the Subsidiary Guaranty, the New Additional Subsidiary
Guarantor by its signature hereto shall become a Subsidiary Guarantor under
the Subsidiary Guaranty with the same force and effect as if originally named
as a Subsidiary Guarantor therein, and each reference to a "Subsidiary
Guarantor" or an "Additional Subsidiary Guarantor" in the Subsidiary Guaranty
shall be deemed to include the New Additional Subsidiary Guarantor.  The New
Additional Subsidiary Guarantor hereby agrees to all the terms and provisions
of the Subsidiary Guaranty applicable to it as an Additional Subsidiary
Guarantor thereunder.

            SECTION 2.  Guaranty.  Without limiting the terms of Section 1, the
New Additional Subsidiary Guarantor hereby absolutely, unconditionally and
irrevocably, jointly and severally,

                  (a)  guarantees the full and punctual payment when due,
            whether at stated maturity, by required prepayment, declaration,
            acceleration, demand or otherwise, of all Obligations of the
            Borrower and each other Obligor, whether for principal, interest,
            fees, expenses or otherwise (including all such amounts which
            would become due but for the operation of the automatic stay under
            Section 362(a) of the United States Bankruptcy Code, 11 U.S.C.
            Section 362(a), and the operation of Sections 502(b) and 506(b) of
            the United States Bankruptcy Code, 11 U.S.C. Section 502(b) and
            Section 506(b)); and

                  (b)  indemnifies and holds harmless each Lender Party and
            each holder of a Note for any and all costs and expenses (including
            reasonable attorney's fees and expenses) incurred by such Lender
            Party or such holder, as the case may be, in enforcing any rights
            under this Supplement or the Subsidiary Guaranty;

provided, however, that the New Additional Subsidiary Guarantor shall be
liable under this Supplement and the Subsidiary Guaranty for the maximum
amount of such liability that can be incurred without rendering this Supplement
and the Subsidiary Guaranty, as it relates to the New Additional Subsidiary
Guarantor, voidable under applicable law relating to fraudulent conveyance or
fraudulent transfer, and not for any greater amount.  This Supplement and the
Subsidiary Guaranty constitute a guaranty of payment when due and not of
collection, and the New Additional Subsidiary Guarantor specifically agrees
that it shall not be necessary or required that any Lender Party or any holder
of any Note exercise any right, assert any claim or demand or enforce any
remedy whatsoever against the Borrower or any other Obligor (or any other
Person) before or as a condition to the obligations of the New Additional
Subsidiary Guarantor under this Supplement or the Subsidiary Guaranty.

            SECTION 3.  Warranties, etc.  The New Additional Subsidiary
Guarantor hereby represents and warrants unto each Lender Party, as of the

                  (a)  each of the representations and warranties set forth in
            Article III of the Subsidiary Guaranty as applied to such New
            Additional Subsidiary Guarantor are true and correct; and

                  (b)  the execution, delivery and performance by the New
            Additional Subsidiary Guarantor of this Supplement are within its
            corporate powers, have been duly authorized by all necessary
            corporate action and constitute the legal, valid and binding
            obligation of the New Additional Subsidiary Guarantor enforceable
            against it in accordance with its terms, subject to applicable
            bankruptcy, insolvency, reorganization, moratorium or similar laws
            from time to time in effect affecting enforceability of creditors,
            rights generally and to general principles of equity.

            SECTION 4.  Subsidiary Guaranty Remains in Full Force and Effect.
Except as expressly supplemented hereby, the Subsidiary Guaranty shall remain
in full force and effect in accordance with its terms.

            SECTION 5.  Governing Law.  THIS SUPPLEMENT SHALL BE DEEMED TO BE
A CONTRACT MADE UNDER AND GOVERNED BY THE INTERNAL LAWS OF THE STATE OF NEW
YORK.

            SECTION 6.  Severability.  Wherever possible each provision of this
Supplement shall be interpreted in such manner as to be effective and valid
under applicable law, but if any provision of this Supplement shall be
prohibited by or invalid under such law, such provision shall be ineffective to
the extent of such prohibition or invalidity, without invalidating the
remainder of such provision or the remaining provisions of this Supplement.

            SECTION 7.  Execution in Counterparts.  This Supplement may be
executed by the parties hereto in several counterparts, each of which shall be
deemed to be an original and all of which shall constitute but one and the same
agreement.

            SECTION 8.  Consent to Jurisdiction.  If the New Additional
Subsidiary Guarantor is organized under the laws of a jurisdiction outside of
the United States, such New Additional Subsidiary Guarantor shall consent to
the jurisdiction of New York courts (including the appointment of an agent to
receive summons and complaints in connection with any litigation) on terms
reasonably satisfactory to the Agent.

            SECTION 9.  Expenses.  Without limiting the provisions of the
Credit Agreement, the New Additional Subsidiary Guarantor agrees to reimburse
the Agent for all reasonable out-of-pocket expenses incurred in connection with
this Supplement, including the reasonable fees and expenses of counsel of the
Agent.

            SECTION 10.  Notices.  The address and facsimile number for all
notices to be delivered to the New Additional Subsidiary Guarantor in
connection with the Subsidiary Guaranty is as set forth in Section 5.4 of the
Subsidiary Guaranty.

            SECTION 11.  Subsidiary Guaranty.  This Supplement hereby
incorporates by reference the provisions of the Subsidiary Guaranty, which
provisions are deemed to be a part hereof, and this Supplement shall be deemed
to be a part of the Subsidiary Guaranty.

            IN WITNESS WHEREOF, the New Additional Subsidiary Guarantor
has duly executed this Supplement to the Subsidiary Guaranty as of the day and
year first above written.

The Bank of Nova Scotia,
as the Agent for the Lenders,
One Liberty Plaza,
New York, N.Y.  10006,
U.S.A.

            - and -

Each of the Lenders party to the Credit
Agreement referred to below


Dear Sirs,

                        Re: ADT LIMITED (the "Company")

            We have been instructed by the Company to address this opinion to
you in connection with the Guaranty, dated as of the 9th January, 1997 (the
"Guaranty"), entered into by the Company in connection with the US$200,000,000
Credit Agreement, dated as of the 9th January, 1997 (the "Credit Agreement")
among ADT Operations, Inc (the "Borrower''), the certain commercial lending
institutions as are or may become parties thereto (collectively, the
"Lenders"), The Bank of Nova Scotia, individually and as Agent for the Lenders
(the "Agent"). This opinion is given pursuant to Section 6.1.9(b) of the
Credit Agreement.

            Unless otherwise defined herein, terms defined in the Guaranty,
have the same meanings when used in this opinion.

            For the purposes of this opinion, we have been supplied with and
have reviewed, and relied upon the following documents:

            (a)   a copy of the executed Credit Agreement;

            (b)   a copy of the executed Guaranty;

            (c)   certified copies of the Certificate of Incorporation,
            Memorandum of Association and Bye-laws of the Company; and

            (d)   a certified copy of the Resolutions of the Board of
            Directors of the Company passed on the 6th January, 1997 (the
            "Certificate"), approving the Guaranty and the Credit Agreement
            and authorizing the execution and delivery of the Guaranty on
            behalf of the Company.

            We have also relied upon our searches of documents of public record
maintained by the Registrar of Companies in Bermuda and of the Cause Book of
the Supreme Court of Bermuda made on the 8th January, 1997 (the "Searches").

            In giving this opinion, we have assumed:

            (a)   the capacity, power and authority of each of the parties to
            the Credit Agreement;

            (b)   the due execution and delivery of the Credit Agreement by
            each of the parties thereto;

            (c)   the conformity to original documents of all documents
            submitted to us as copies and the authenticity and completeness of
            all original documents;

            (d)   that the information disclosed by our Searches has not been
            materially altered and that the Searches did not fail to disclose
            any material information which had been delivered for filing or
            registration, but was not disclosed or did not appear on the
            public file at the time of the Searches;

            (e)   that the Guaranty and the Credit Agreement are legal, valid,
            binding and enforceable under the laws of the State of New York, by
            which they are expressed to be governed;

            (f)   the truth, accuracy and completeness of all factual
            representations and warranties made in the Certificate, the
            Guaranty and the Credit Agreement;

            (g)   the genuineness of all signatures on the documents which we
            have examined; and

            (h)   that there are no provisions of the laws of any
            jurisdiction, other than Bermuda, which would have any implication
            in relation to the opinion expressed herein.

            The opinion is limited to Bermuda law as applied by the Bermuda
Courts.  We have made no investigation of the laws of any jurisdiction
other than Bermuda and neither express nor imply any opinion as to any
other law, in particular the laws of the United States of America.

            Based upon the foregoing, subject to the qualifications set out
below, to matters not disclosed to us and matters of fact which would affect
the conclusions set out below, and having regard to such legal considerations
as we deem relevant, we are of the opinion that insofar as the present laws of
Bermuda are concerned:

            (1)   The Company is a company duly incorporated and validly
            existing under and in compliance with Bermuda law.

            (2)   The Company has the corporate power and authority to enter
            into and perform the Guaranty and has taken all necessary action
            to authorise the execution, delivery and performance of the
            Guaranty.

            (3)   The Guaranty has been duly executed and validly delivered.

            (4)   The obligations of the Company as set out in the Guaranty
            constitute legal, valid and binding obligations of the Company.

            (5)   The Company having been designated as non-resident for the
            purposes of the Exchange Control Act 1972, it is not necessary for
            the consent of any authority or agency of Bermuda to be obtained
            to enable the Company to enter into and perform its obligations
            set out in the Guaranty.

            (6)   The obligations of the Company under the Guaranty will rank
            at least pari passu in priority of payment with all other unsecured
            unsubordinated indebtedness of the Company other than indebtedness
            which is preferred by virtue of any provision of Bermuda law of
            general application.

            (7)   The execution, delivery and performance of the Guaranty by
            the Company (i) does not and will not violate the Certificate of
            Incorporation, Bye-laws or Memorandum of Association of the
            Company; (ii) conflict with any law or governmental rule or
            regulation of Bermuda (including the Companies Act of 1981 of
            Bermuda); and (iii) as far as can be ascertained from the Searches
            does not and will not violate or conflict with any judgment,
            order, decree, injunction or award of any authority, agency or
            court in Bermuda to which the Company is subject.

            (8)   As far as can be ascertained from the Searches, no
            litigation, arbitration or administrative proceeding of or before
            any court, arbitrator or governmental instrumentality of or in
            Bermuda is, to the best of our knowledge, pending with respect to
            the Credit Agreement, the Guaranty or the transactions
            contemplated thereby.

            (9)   The Company will be permitted to make all payments under the
            Guaranty free of any deduction or withholding therefrom in Bermuda
            and such payments will not be subject in the hands of the Lenders
            or the Agents to any Tax imposed by the government of Bermuda or
            any taxing authority thereof or therein.

            (10)  The entry into, performance and enforcement of the Guaranty
            will not give rise to any registration fee or to any stamp, excise
            or other similar tax imposed by the government of Bermuda or any
            taxing authority thereof or therein.

            (11)  It is not necessary or advisable under the laws of Bermuda
            in order to ensure the validity, effectiveness or enforceability
            of the Guaranty that the Guaranty be filed, registered or recorded
            in any public office or elsewhere in Bermuda.

            (12)  The choice of the laws of the State of New York to govern the
            Guaranty is a proper, valid and binding choice of law and will be
            recognised and applied by the Courts of Bermuda assuming that such
            choice of law is a valid and binding choice of law under the laws
            of the State of New York.

            (13)  The submission by the Company to the non-exclusive
            jurisdiction of the courts of New York pursuant to Section 5 of
            the Guaranty is valid and binding upon the Company, assuming that
            such submission is accepted by the courts of New York, and is not
            subject to revocation.

            (14)  A final and conclusive judgment obtained in the courts of
            the State of New York under which a sum of money is payable, not
            being a sum payable in respect of taxes or other charges of a like
            nature or in respect of a fine or other penalty or in respect of
            Multiple Damages (as defined in The Protection of Trading Interest
            Act 1981), would be enforced as a debt against the Company by an
            action in the Supreme Court of Bermuda without a re-examination of
            the merits of the case under the Common Law Doctrine of
            Obligation, provided that such judgment was not obtained by fraud
            or that its enforcement would not be contrary to public policy in
            Bermuda or that the proceedings in which the same was obtained
            were not contrary to natural justice.

            (15)  It is not necessary under the laws of Bermuda (a) in order to
            enable the Agents or the Lenders to enforce their rights under the
            Guaranty or (b) by reason of the execution of the Guaranty or the
            Credit Agreement or the performance by the Lenders of their
            obligations under the Credit Agreement, that the Lenders or the
            Agents be licensed or qualified or otherwise entitled to carry on
            business in Bermuda.

            (16)  None of the Agents or the Lenders is or will be deemed to be
            resident, domiciled, carrying on business or subject to taxation in
            Bermuda by reason only of  the entry into, performance and/or
            enforcement of the Company Guaranty or the Credit Agreement.

                  Our reservations as follows:

A.          We express no opinion as to whether specific performance or
injunctive relief, being equitable remedies, would necessarily be available in
respect of any of the obligations of the
Company as set out in the Guaranty.

B.          We express no opinion as to the validity or the binding effect of
any obligations set out in the Credit Agreement or the Guaranty which provides
for the payment of a higher rate of interest on overdue amounts than on amounts
which are current. A Bermuda court, even if it were applying the laws of the
State of New York, might not give effect to such a provision if it could be
established that the amount expressed as being payable was such that the
provision was in the nature of a penalty; that is to say a requirement for a
stipulated sum to be paid irrespective of, or necessarily greater than, the
loss likely to be sustained.

C.          The obligations of the Company under the Guaranty will be subject
to any laws from time to time in effect relating to bankruptcy or liquidation
or any other laws or other legal procedures affecting generally the
enforcement of creditors' rights and may also be the subject of the statutory
limitation of the time within which such proceedings may be brought.

D.          The registration of a New York Court judgment in the Supreme Court
of Bermuda involves the conversion of the judgment debt into Bermuda dollars,
but the Controller of Foreign Exchange has indicated that the present policy
is to give the consents necessary for any Bermuda dollar award made by the
Supreme Court of Bermuda as aforesaid to be converted into external currency.

E.          Any provision in the Guaranty that certain calculations and/or
certificates will be conclusive and binding will not be effective if such
calculations are fraudulent or erroneous on their face and will not
necessarily prevent juridical enquiries into the merits of any claim by an
aggrieved party.

F.          To the extent that the Credit Agreement, Guaranty or the
transactions contemplated thereunder, create or give rise to the creation of
any charge over any assets of the Company, or create a charge on property in
Bermuda which is acquired by a Company incorporated outside of Bermuda, such
Charge will be registrable under Part V of the Companies Act, 1981 of Bermuda.
The fee payable for registration of a Charge (securing a sum greater than
US$1,000,000) is $425.00. Registration is not compulsory and there is no time
limit within which it must be effected. However, to the extent that matters of
priority of competing charges over such assets are determined in accordance
with Bermuda law, any charge registered under the said Act will have priority
based on the date that it is registered and not on the date of its creation
and will have such priority over any unregistered charge and on any charge
which is subsequently registered under the said Act in each case, which
pertains to such assets.

G.          A Bermuda court may refuse to give effect to any provisions of the
Guaranty in respect of costs of unsuccessful litigation brought before the
court or where that court has itself made an order for costs.

H.          We express no opinion as to any law other than Bermuda law and none
of the opinions expressed herein relates to compliance with or matters governed
by the laws of any jurisdiction except Bermuda. Where an obligation is to be
performed in a jurisdiction other than Bermuda, the Courts of Bermuda may
refuse to enforce it to the extent that such performance would be illegal or
contrary to public policy under the laws of such other jurisdiction.

I.          The Searches showed a cause of action in which the Company is named
as defendant. The Acton was commenced in 1991 under action number 01299. The
Plaintiff is Laidlaw Investments (Barbados) Ltd. We are unable to verify
whether this litigation is proceeding, or has been discontinued, and whether
if it proceeded any judgment was rendered against the Company, whether this
judgment would have any material effect on the Company.

This opinion is issued on the basis that it will be governed by and construed
in accordance with the laws of Bermuda and that any legal proceedings with
respect thereto will be brought in the Courts of Bermuda. It is issued solely
for your benefit for the purpose of the transactions described in the Credit
Agreement and the Guaranty and it is not to be relied upon by any other Person
(other than permitted assigns under the Credit Agreement), or for any other
purpose, without our prior written consent.

                               Yours faithfully,


                                                                   EXHIBIT L-1


                     [LETTERHEAD OF DAVIS POLK & WARDWELL]


                                                            ____________, 1997


The Bank of Nova Scotia,
   as Agent
One Liberty Plaza
New York, New York 10006

                  -and-

Each of the Lenders party to the
Credit Agreement referred to below

Dear Sirs:

               We have participated in the preparation of the $US200,000,000
Credit Agreement, dated as of January 9, 1997 (the "Credit Agreement"), among
ADT Operations, Inc. (the "Borrower"), the financial institutions parties
thereto as lenders (collectively, the "Lenders") and The Bank of Nova Scotia,
individually, as issuer of letters of credit thereunder and as agent for the
Lenders (the "Agent"). Unless otherwise defined herein, terms used herein have
the meanings provided in the Credit Agreement. This opinion is given pursuant
to Section 6.1.9(b) of the Credit Agreement.

               We have examined originals or copies, certified or otherwise
identified to our satisfaction, of such documents, corporate records,
certificates of public officials and other instruments as in our judgment are
necessary or appropriate to enable us to render the opinions expressed below.
These documents, records, certificates and instruments include the following
(in each case dated as of the date of the Credit Agreement unless otherwise
indicated):

            (a) An executed copy of the Credit Agreement;

            (b) An executed copy of each of the Notes issued on January 14,
1997 (the "Notes");

            (c) An executed copy of the ADT Limited Guaranty; and

            (d) An executed copy of the Subsidiary Guarantor Guaranty.

               The documents referred to in items (a) through (d) above are
referred to herein collectively as the "Credit Documents". The Borrower, ADT
Limited and the Subsidiary Guarantors are collectively referred to as the
"Credit Parties".

               On the basis of the foregoing, and in reliance thereon, and
subject to the limitations, qualifications, assumptions and exceptions set
forth herein, we are of the opinion that as of the date hereof:

               1. Each Credit Document (other than the Notes) constitutes a
valid and binding agreement of each Credit Party party thereto, and each Note
constitutes a valid and binding obligation of the Borrower, in each case
enforceable against such Credit Party or the Borrower, as the case may be, in
accordance with its terms, subject to applicable bankruptcy, insolvency and
similar laws affecting creditors' rights generally and to general principles
of equity.

               2. None of the execution and delivery on the date hereof by any
Credit Party of any Credit Document to which  it is a party or the performance
by such Credit Party of its obligations thereunder (a) conflicts with, results
in a breach or violation of, or constitutes a default under, any of the terms,
conditions or provisions of (i) any agreement or instrument listed on Schedule
1 hereto (each a "Designated Agreement") or (ii) the Delaware General
Corporation Law or any federal or New York State law, statute, rule or
regulation binding on any Credit Party which in our experience is normally
applicable to general business corporations and to transactions of the type
contemplated by the Credit Documents or (b) results in the creation of any
Lien upon any assets of any Credit Party under any Designated Agreement.

               3. Neither the making of the Loans nor the  issuance of the
Letters of Credit as provided in the Credit Agreement violates Regulation G, U
or X of the Board of Governors of the Federal Reserve System.

               4. No governmental consents, approvals, authorizations,
registrations, declarations or filings (other than those that have been duly
obtained and are in full force and effect and routine filings with the
Securities and Exchange Commission) are required to be made or obtained by any
Credit Party under the Delaware General Corporation Law or any federal or New
York State law in connection with (a) the making of the Loans or the issuance
of the Letters of Credit under the Credit Agreement, (b) the execution,
delivery and performance by each Credit Party thereto of any of the Credit
Documents or (c) the legality, validity, binding effect or enforceability of
any Credit Document.

               5. No Credit Party is an "investment company" as such term is
defined in the Investment Company Act of 1940, as amended.

               6. No Credit Party is a "holding company", or a "subsidiary
company" of a "holding company", or an "affiliate" of a "holding company" or
of a "subsidiary company" of a "holding company" within the meaning of the
Public Utility Holding Company Act of 1935, as amended.

               7. The obligations of the Borrower and ADT Limited under the
Credit Documents constitute "Senior Indebtedness" and "Guarantor Senior
Indebtedness", respectively, in each case as defined in each of the Senior
Subordinated Note Indenture and the LYONS Indenture.

                The foregoing opinion is subject to the following
qualifications:

               (a) Our opinion is subject to the effect of, and we express no
opinion as to the possible application to the transactions contemplated by the
Credit Documents of, any applicable fraudulent conveyance, fraudulent transfer
or similar law.

               (b) We express no opinion as to provisions in the Credit
Documents which purport to create rights of set-off in favor of participants
or which provide for set-off to be made otherwise than in accordance with
applicable laws.

               (c) We have assumed (i) the genuineness of all signatures of all
parties to any Credit Document, (ii) that each Person that is a party to any
Credit Document has full power, authority and legal right under its charter
and other governing documents and laws applicable to it to execute, deliver
and perform its obligations under the Credit Documents to which it is a party,
(iii) that the execution, delivery and performance by each Credit Party of
each Credit Document to which it is a party have been duly authorized by all
necessary corporate action and do not conflict with the charter or other
governing documents of such Credit Party and (iv) that each of the Credit
Documents constitutes a valid and binding agreement of each Person party
thereto that is not a Credit Party, enforceable against each such Person in
accordance with its terms.

               We are members of the Bar of the State of New York and the
foregoing opinion is limited to the laws of the State of New York, the federal
laws of the United States of America and the Delaware General Corporation Law.

Each of the Lenders
party to the Credit
Agreement referred to below

Dear Sirs:

            We have acted as counsel to ADT Operations, Inc., a Delaware
corporation (the "Borrower"), in connection with the US $200,000,000 Credit
Agreement dated as of January 9, 1997 (the "Credit Agreement") among the
Borrower, the financial institutions parties thereto (collectively, the
"Lenders") and The Bank of Nova Scotia, individually and as agent (in such
capacity, the "Agent") for the Lenders. Unless otherwise defined herein, terms
used herein have the respective meanings provided in the Credit Agreement.

            In this connection, we have examined originals, or certified or
photostatic copies, of such documents, corporate records, certificates of
public officials and other instruments as we have deemed necessary for
purposes of this opinion, including without limitation:

            (a)   the Credit Agreement;
            (b)   each of the Notes;
            (c)   the ADT Limited Guaranty;
            (d)   the Subsidiary Guarantor Guaranty; and
            (e)   the Subordination Agreement.

            The documents referred to in items (a) through (e) above are
referred to herein collectively as the "Credit Documents". The Borrower, ADT
Limited and each Subsidiary Guarantor are collectively referred to as the
"Credit Parties".

            We have assumed the genuineness of all signatures, the
authenticity of all documents tendered to us as originals, the conformity to
original documents of all documents submitted to us as certified, photostatic
or facsimile copies and the corporate authority of any individual executing
such documents.

            Based upon the foregoing and such other investigations of fact and
law as we have deemed appropriate, it is our opinion that:

            1.    Each of the Credit Parties organized under the laws of the
State of Delaware (the "Delaware Credit Parties"), which Delaware Credit
Parties are set forth on Exhibit A attached hereto, is a corporation duly
incorporated, validly existing and in good standing under the laws of the
State of Delaware with corporate power and authority under such laws to (a)
own, lease and operate its properties and conduct its business and (b)
execute, deliver and perform the Credit Documents to which it is a party.

            2.    Each Delaware Credit Party is qualified to do business as a
foreign corporation and is in good standing in each other jurisdiction in
which, to our knowledge, its properties or business require such
qualification, provided that any failure to be so qualified does not create a
materially adverse effect on the Delaware Credit Parties taken as a whole.

            3.    The execution and delivery by the Delaware Credit Parties of
the Credit Documents to which they are parties, and the performance by such
Delaware Credit Parties of their respective obligations thereunder, do not and
will not result in any violation of the charter and by-laws of any of the
Delaware Credit Parties.

            4.    The Credit Documents executed by the Delaware Credit Parties
have been duly executed and delivered by such Delaware Credit Parties.

            5.    The execution, delivery and performance by the Delaware
Credit Parties of the Credit Documents executed by such Delaware Credit
Parties have been duly authorized.

            We are members of the Bar of the State of New York and the
foregoing opinion is limited to the laws of the State of New York, the federal
laws of the United States of America and the General Corporation Law of the
State of Delaware.

            This opinion is made as the date hereof and we assume no
obligation to update or supplement this opinion to reflect any facts or
circumstances which may hereafter come to our attention or any changes in law
which may hereafter occur. This opinion is rendered solely to you and is
solely for your benefit (and the benefit of your permitted assigns under the
Credit Agreement) in connection with the above matter. This opinion may not be
relied upon by you for any other purpose or relied upon by any other Person
without our prior written consent.

                              Very truly yours,

The Bank of Nova Scotia,
   as Agent
One Liberty Plaza
New York, New York  10006

Dear Sirs:

               I have participated in the preparation of the US$200,000,000
Credit Agreement, dated as of January 9, 1997 (the "Credit Agreement"), among
ADT Operations, Inc. (the "Borrower"), the financial institutions parties
thereto (the "Lenders") and The Bank of Nova Scotia, individually, as issuer
of letters of credit thereunder and as agent for the Lenders ( in such
capacity, the "Agent"). Unless otherwise defined herein, terms used herein
have the meanings provided in the Credit Agreement.

               I have examined originals or copies, certified or otherwise
identified to my satisfaction, of such documents, corporate records,
certificates of public officials and other instruments as in my judgment are
necessary or appropriate to enable me to render the opinions expressed below.
These documents, records, certificates and instruments include the following
(in each case dated as of the date of the Credit Agreement unless otherwise
indicated):

               (a) An executed copy of the Credit Agreement;

               (b) An executed copy of the Note;

               (c) An executed copy of the ADT Limited Guaranty; and

               (d) An executed copy of the Subsidiary Guarantor Guaranty.

               The documents referred to in items (a) through (d) above are
referred to herein collectively as the "Credit Documents". The Borrower, ADT
Limited and each Subsidiary Guarantor are collectively referred to as the
"Credit Parties".

               On the basis of the foregoing, and in reliance thereon, and
subject to the limitations, qualification, assumptions and exceptions set
forth herein, I am of the opinion that as of the date hereof:

               1. To the best of my knowledge, neither the execution and
delivery on the date hereof by the Credit Parties of the Credit Documents to
which they are parties, the consummation on the date hereof of the
transactions contemplated thereby nor the performance by such Credit Parties
of their obligations thereunder conflicts with, results in a breach or
violation of, or constitutes a default under, any of the terms, conditions or
provisions of any order, writ, injunction, or decree of any court or
governmental authority applicable to ADT Limited or any of its Subsidiaries.

               2. To the best of my knowledge, there is no litigation, action,
proceeding or labor controversy pending or threatened against any Credit Party
in which an injunction or order has been entered preventing the making of the
Loans or the issuance or maintenance of the Letters of Credit, or which
questions the validity or enforceability of any of the Credit Documents or the
transactions contemplated thereby.

               I am a member of the Bar of the State of New York and the
foregoing opinion is limited to the laws of the State of New York and federal
laws of the United States of America.

               This opinion is rendered solely to you and is solely for your
benefit (and the benefit of your permitted assigns under the Credit Agreement)
in connection with the above matter. This opinion may not be relied upon by
you for any other purpose or relied upon by any other Person without my prior
written consent.

                                           Sincerely,

   from time to time to the Credit
   Agreement referred to below

      - and -

The Bank of Nova Scotia,
   as Agent for the Lenders
One Liberty Plaza
New York, New York 10006


Ladies and Gentlemen:

               This letter is being delivered to you pursuant to clause (d) of
Section 6.1.9 of the US$200,000,000 Credit Agreement, dated as of January 9,
1997 (the "Credit Agreement"), among ADT Operations, Inc., a Delaware
corporation (the "Borrower"), the various financial institutions as are or may
become parties thereto (collectively, the "Lenders") and The Bank of Nova
Scotia, individually and as agent (the "Agent") for the Lenders. Unless
otherwise defined herein or the context otherwise requires, capitalized terms
used herein have the meanings provided in the Credit Agreement.

               I have acted as general counsel to ADT Group plc, a company
organized under the laws of England ("ADT Group plc"), and ADT Security
Services, Inc. (formerly known as ADT Security Systems, Inc.), a Delaware
corporation (together with ADT Group plc, the "Subject Companies"), in
connection with the Subordination Agreement, dated as of January 9, 1997 (the
"Subordination Agreement"), made by the Subject Companies in favor of the
holders from time to time of Senior Indebtedness (as defined in the
Subordination Agreement), and, in that regard, I have examined originals, or
certified or photostatic copies, of such documents, corporate records,
certitudes of public officials and other instruments as I have deemed
necessary for purposes of this letter, including, without limitation, the
Subordination Agreement.

               In my examination of the Subordination Agreement, I have
assumed the authenticity of all its documents submitted to me as originals,
the genuineness of all signatures, the conformity to original documents
submitted to me as certified copies of photocopies and the authenticity of the
originals of such letter documents.

               Based upon the foregoing examination of documents and
assumptions and upon such other investigation as I have deemed necessary, I am
of the opinion that:

               1. ADT Group plc is a company duly incorporated and validly
existing under and in compliance with English law.

               2. Each of the Subject Companies has the corporate power and
authority to enter into and perform the Subordination Agreement and has taken
all necessary action to authorize the execution, delivery and performance of
the Subordination Agreement.

               3. The Subordination Agreement has been duly executed and validly
delivered by ADT Group plc.

               4. The Subordination Agreement executed and delivered by each of
the Subject Companies constitutes a legal, valid and binding obligation of
each Subject Company, enforceable against it in accordance with its terms.

               5. The choice of the laws of the State of New York to govern the
Subordination Agreement is a proper, valid and binding choice of law and will
be recognized and applied by the courts of England assuming that such choice
of law is a valid and binding choice of law under the laws of the State of New
York.

               6. The submission by ADT Group plc to the jurisdiction of the
courts of New York pursuant to Section 16 of the Subordination Agreement is
valid and binding upon ADT Group plc, assuming that such submission is
accepted by the courts of New York.

               This opinion letter is being furnished to you for your use in
connection with the transactions  contemplated by the Subordination Agreement
and may not be relied upon by any other person without my prior written
consent.

                                           Very truly yours,

                              GUARANTY PROVISIONS

            SECTION 2.1.  Guaranty.  ADT Limited hereby absolutely,
unconditionally and irrevocably

                  (a)  guarantees the full and punctual payment when due,
            whether at stated maturity, by required prepayment, declaration,
            acceleration, demand or otherwise, of all Obligations of the
            Borrower and each other Obligor now or hereafter existing, whether
            for principal, interest, Reimbursement Obligations, fees, expenses
            or otherwise (including all such amounts which would become due
            but for the operation of the automatic stay under Section 362(a)
            of the United States Bankruptcy Code, 11 U.S.C. Section  362(a),
            and the operation of Sections 502(b) and 506(b) of the United
            States Bankruptcy Code, 11 U.S.C. Section  502(b) and Section
            506(b)); and

                  (b)  indemnifies and holds harmless each Lender Party and
            each holder of a Note for any and all costs and expenses (including
            reasonable attorney's fees and expenses) incurred by such Lender
            Party or such holder, as the case may be, in enforcing any rights
            under this Guaranty.

This Guaranty constitutes a guaranty of payment when due and not of
collection, and ADT Limited specifically agrees that it shall not be necessary
or required that any Lender Party or any holder of any Note exercise any
right, assert any claim or demand or enforce any remedy whatsoever against the
Borrower or any other Obligor (or any other Person) before or as a condition
to the obligations of ADT Limited hereunder.

            SECTION 2.2.  Guaranty Absolute, etc.  This Guaranty shall in all
respects be a continuing, absolute, unconditional and irrevocable guaranty of
payment, and shall remain in full force and effect until all Obligations of the
Borrower and each other Obligor have been paid in full, all obligations of ADT
Limited hereunder shall have been paid in full and all Commitments shall have
terminated.  ADT Limited guarantees that the Obligations of the Borrower and
each other Obligor and their respective Subsidiaries will be paid strictly in
accordance with the terms of the Credit Agreement and each other Loan Document
under which they arise, without regard (to the fullest extent permitted under
applicable law) to any law, regulation or order now or hereafter in effect in
any jurisdiction affecting any of such terms or the rights of any Lender Party
or any holder of any Note with respect thereto (and ADT Limited hereby waives
to the fullest extent it may do so any right or rights it may have under any
such law, regulation or order).  Without limiting the generality of the
foregoing, the liability of ADT Limited under this Guaranty shall be absolute,
unconditional and irrevocable irrespective of:

                  (a)  any lack of genuineness, validity, legality or
            enforceability of the Credit Agreement, any Note, any Letter of
            Credit or any other Loan Document (other than this Guaranty) or of
            any of the Obligations (other than the Obligations of ADT Limited
            hereunder);

                  (b)  the failure of any Lender Party or any holder of any
            Note

                        (i)  to assert any claim or demand or to enforce any
                  right or remedy against the Borrower, any other Obligor or
                  any other Person (including any other guarantor) under the
                  provisions of the Credit Agreement, any Note, any Letter of
                  Credit, any other Loan Document or otherwise, or

                        (ii)  to exercise any right or remedy against any other
                  guarantor (including any other Guarantor) of, or collateral
                  securing, any Obligations of the Borrower or any other
                  Obligor;

                  (c)  any change in the time, manner or place of payment of,
            or in any other term of, all or any of the Obligations of the
            Borrower or any other Obligor (other than ADT Limited), or any
            other extension, compromise or renewal of any Obligation of the
            Borrower or any other Obligor (other than ADT Limited);

                  (d)  any reduction, limitation, impairment or termination of
            the Obligations of the Borrower or any other Obligor (other than
            ADT Limited) for any reason, including any claim of waiver,
            release, surrender, alteration or compromise, and shall not be
            subject to (and ADT Limited hereby waives any right to or claim
            of) any defense or setoff, counterclaim, recoupment or termination
            whatsoever by reason of the invalidity, illegality,
            nongenuineness, irregularity, compromise, unenforceability of, or
            any other event or occurrence affecting, the Obligations of the
            Borrower, any other Obligor (other than ADT Limited) or otherwise;

                  (e)  any amendment to, rescission, waiver, or other
            modification of, or any consent to departure from, any of the
            terms of the Credit Agreement, any Note, any Letter of Credit or
            any other Loan Document (other than this Guaranty);

                  (f)  any addition, exchange, release, surrender or
            non-perfection of any collateral, or any amendment to or waiver or
            release or addition of, or consent to departure from, any other
            guaranty (or any other Guarantee), held by any Lender Party or any
            holder of any Note securing any of the Obligations of the Borrower
            or any other Obligor; or

                  (g)  any other circumstance which might otherwise constitute
            a defense available to, or a legal or equitable discharge of, the
            Borrower, any other Obligor, any surety or any other guarantor (or
            any other Guarantor).

            SECTION 2.3.  Stay of Acceleration, Reinstatement, etc.  ADT
Limited agrees that, if acceleration of the time for payment of any amount
payable by the Borrower under the Credit Agreement, the Notes or any other
Loan Document or of compliance by the Borrower with its obligations under
Section 4.7 of the Credit Agreement is, in either case, stayed upon the
occurrence with respect to the Borrower of any Event of Default described in
clause (b) or (d) of Section 9.1.9 of the Credit Agreement, all such amounts
and obligations otherwise subject to acceleration or compliance under the terms
of the Credit Agreement shall nonetheless be payable and performed by ADT
Limited hereunder forthwith on demand by the Agent made at the request of the
requisite proportion of the Lenders specified in Section 9.3 of the Credit
Agreement.  ADT Limited agrees that this Guaranty shall continue to be
effective or be reinstated, as the case may be, if at any time any payment (in
whole or in part) of any of the Obligations is rescinded or must otherwise be
restored by any Lender Party or any holder of any Note, upon the insolvency,
bankruptcy or reorganization of the Borrower, any other Obligor (other than
ADT Limited) or otherwise, all as though such payment had not been made.

            SECTION 2.4.  Waiver, etc.  ADT Limited hereby waives  promptness,
diligence, notice of acceptance and any other notice with respect to any of
the Obligations of the Borrower or any other Obligor and this Guaranty and any
requirement that any Agent, any other Lender Party or any holder of any Note
protect, secure, perfect or insure any security interest or Lien, or any
property subject thereto, or exhaust any right or take any action against the
Borrower, any other Obligor or any other Person (including any other guarantor
and any other Guarantor) or entity or any collateral securing the Obligations
of the Borrower or any other Obligor, as the case may be.

            SECTION 2.5.  Subrogation.  ADT Limited hereby agrees that it will
not exercise any rights which it may now or hereafter acquire against the
Borrower or any other Obligor that arise from the existence, payment,
performance or enforcement of ADT Limited's obligations under this Guaranty
or any other Loan Document, including any right of subrogation, reimbursement,
exoneration, or indemnification, any right to participate in any claim or
remedy of the Lender Parties against the Borrower or any other Obligor or any
collateral which any Agent now has or hereafter acquires, whether or not such
claim, remedy or right arises in equity, or under contract, statute or common
law, including the right to take or receive from the Borrower or any other
Obligor, directly or indirectly, in cash or other property  or by set-off or
in any manner, payment or security on account of such claim or other rights,
until the Obligations have been paid in full in cash and the Commitments have
been terminated.  If any amount shall be paid to ADT Limited in violation of
the preceding sentence and the Obligations shall not have been paid in cash in
full and the Commitments have not been terminated, such amount shall be deemed
to have been paid to ADT Limited for the benefit of, and held in trust for,
the Lender Parties, and shall forthwith be paid to the Lender Parties to be
credited and applied to the Obligations, whether matured or unmatured.  ADT
Limited acknowledges that it will receive direct and indirect benefits from
the financing arrangements contemplated by the Credit Agreement and that the
agreement set forth in this Section is knowingly made in contemplation of such
benefits.

            SECTION 2.6.  Successors, Transferees and Assigns; Transfers of
Notes, etc.  This Guaranty shall:

                  (a)  be binding upon ADT Limited, and its successors,
            transferees and assigns; and

                  (b)  inure to the benefit of and be enforceable by the Agent
            and each other Lender Party.

Without limiting the generality of clause (b), any Lender may assign or
otherwise transfer (in whole or in part) any Note or Loan held by it to any
other Person or entity, and such other Person or entity shall thereupon become
vested with all rights and benefits in respect thereof granted to such Lender
under any Loan Document (including this Guaranty) or otherwise, subject,
however, to the provisions of Section 11.11 and Article X of the Credit
Agreement.

            SECTION 2.7.  Payments Free and Clear of Taxes, etc.  ADT Limited
hereby agrees that:

                  (a)  Any and all payments made by ADT Limited hereunder
            shall be made in accordance with Section 5.6 of the Credit
            Agreement free and clear of, and without deduction for, any and
            all present or future taxes, levies, imposts, deductions, charges
            or withholdings, and all liabilities with respect thereto,
            excluding, in the case of each Lender Party or any holder of a
            Note, taxes imposed on its income, and franchise taxes imposed on
            it, by the jurisdiction under the laws of which such Lender Party
            or such holder, as the case may be, is organized and by any
            political subdivision thereof and, in the case of each Lender,
            taxes imposed on its income, and franchise taxes imposed on it, by
            the jurisdiction of such Lender's Domestic Office or LIBOR Office
            and any political subdivision thereof (all such non-excluded
            taxes, levies, imposts, deductions, charges, withholdings and
            liabilities being hereinafter referred to as "Taxes").  If ADT
            Limited shall be required by law to deduct any Taxes from or in
            respect of any sum payable hereunder to any Lender Party or any
            holder of a Note

                        (i)  the sum payable shall be increased as may be
                  necessary so that after making all required deductions
                  (including deductions applicable to additional sums payable
                  under this Section) such Lender Party or such holder, as the
                  case may be, receives an amount equal to the sum it would
                  have received had no such deductions been made,

                        (ii)  ADT Limited shall make such deductions, and

                        (iii)  ADT Limited shall pay the full amount deducted
                  to the relevant taxation authority or other authority in
                  accordance with applicable law.

                  (b)  ADT Limited shall pay any present or future stamp or
            documentary taxes or any other excise or property taxes, charges or
            similar levies which arise from any payment made hereunder or from
            the execution, delivery or registration of, or otherwise with
            respect to, this Guaranty (hereinafter referred to as "Other
            Taxes").

                  (c)  ADT Limited hereby indemnifies and holds harmless each
            Lender Party and each holder of a Note for the full amount of
            Taxes or Other Taxes (including, without limitation, any Taxes or
            Other Taxes imposed by any jurisdiction on amounts payable under
            this Section) paid by such Lender Party or such holder, as the
            case may be, and any liability (including penalties, interest and
            expenses) arising therefrom or with respect thereto, whether or
            not such Taxes or Other Taxes were correctly or legally asserted.

                  (d)  Within 30 days after the date of any payment of Taxes or
            Other Taxes, ADT Limited will furnish to the Agent the original or
            a certified copy of a receipt evidencing payment thereof.  If no
            Taxes or Other Taxes are payable in respect of any payment
            hereunder to any Lender Party or any holder of a Note, ADT Limited
            will furnish to the Agent upon its reasonable request (which
            request shall not be made more than once per Fiscal Year) a
            certificate from each appropriate taxing authority, or an opinion
            of counsel acceptable to the Agent, in either case stating that
            such payment is exempt from or not subject to Taxes or Other Taxes.

                  (e)  Without prejudice to the survival of any other
            agreement of ADT Limited hereunder, the agreements and obligations
            of ADT Limited contained in this Section 2.7 shall survive the
            payment in full of the principal of and interest on the Loans.

            SECTION 2.8.  Judgment.  ADT Limited hereby agrees that to the
fullest extent permitted by applicable law:

                  (a)  if, for the purposes of obtaining judgment in any
            court, it is necessary to convert a sum due hereunder in United
            States Dollars into another currency, ADT Limited agrees that the
            rate of exchange used shall be that at which in accordance with
            normal banking procedures the Agent could purchase United States
            Dollars with such other currency on the Business Day preceding
            that on which final judgment is given; and

                  (b)  the obligation of ADT Limited in respect of any sum due
            from it to any Lender Party or any holder of a Note hereunder
            shall, notwithstanding any judgment in a currency other than
            United States Dollars, be discharged only to the extent that on
            the Business Day following receipt by such Lender Party or such
            holder, as the case may be, of any sum adjudged to be so due in
            such other currency such Lender Party or such holder, as the case
            may be, may, in accordance with normal banking procedures,
            purchase United States Dollars with such other currency; in the
            event that the United States Dollars so purchased are less than
            the sum originally due to such Lender Party in United States
            Dollars, ADT Limited, as a separate obligation and notwithstanding
            any such judgment, hereby indemnifies and holds harmless such
            Lender Party and such holder against such loss, and if the United
            States Dollars so purchased exceed the sum originally due to such
            Lender Party or such holder in United States Dollars, such Lender
            Party or such holder, as the case may be, shall remit to ADT
            Limited such excess.

            SECTION 2.9.  Consent to Jurisdiction; Waiver of Immunities.  ADT
Limited hereby acknowledges and agrees that:

                  (a)  It has irrevocably submitted to the jurisdiction of the
            courts of the State of New York and of the United States District
            Court for the Southern District of New York for the purposes of
            any action or proceeding arising out of or relating to this
            Guaranty, and ADT Limited hereby irrevocably agrees that all
            claims in respect of such action or proceeding may be heard and
            determined in such New York state or federal court.  ADT Limited
            hereby irrevocably waives, to the fullest extent it may
            effectively do so, the defense of an inconvenient forum to the
            maintenance of such action or proceeding.  ADT Limited hereby
            irrevocably appoints Kay, Collyer & Boose (the "Process Agent"),
            with an office on the date hereof at 1 Dag Hammarskjold Plaza, New
            York, New York, United States (Attention:  Eli Schoenfield), as
            its agent to receive on behalf of ADT Limited and its property
            service of copies of the summons and complaint and any other
            process which may be served in any such action or proceeding.  Such
            service may be made by mailing or delivering a copy of such
            process to ADT Limited in care of the Process Agent at the Process
            Agent's above address, and ADT Limited hereby irrevocably
            authorizes and directs the Process Agent to accept such service on
            its behalf.  As an alternative method of service, ADT Limited also
            irrevocably consents to the service of any and all process in any
            such action or proceeding by the mailing of copies of such process
            to ADT Limited at its address specified on the signature page
            hereof.  ADT Limited hereby agrees that in the event the Process
            Agent is no longer resident in New York, New York, it shall
            appoint a successor Process Agent resident in New York, New York
            reasonably acceptable to the Agent, which successor Process Agent
            shall thereafter be the Process Agent hereunder.  ADT Limited
            agrees that a final judgment in any such action or proceeding
            shall be conclusive and may be enforced in other jurisdictions by
            suit on the judgment or in any other manner provided by law.

                  (b)  Nothing in this Section shall affect the right of any
            Lender Party or any holder of any Note to serve legal process in
            any other manner permitted by law or affect the right of any
            Lender Party or any holder of any Note to bring any action or
            proceeding against ADT Limited or any of its properties in the
            courts of any other jurisdictions.

                  (c)  To the extent that ADT Limited has or hereafter may
            acquire any immunity from jurisdiction of any court or from any
            legal process (whether through service or notice, attachment prior
            to judgment, attachment in aid of execution, execution or
            otherwise) with respect to itself or its property, ADT Limited
            hereby irrevocably waives, to the fullest extent permitted under
            applicable law, such immunity in respect of its obligations under
            this Guaranty.


                                  ARTICLE III

                        REPRESENTATIONS AND WARRANTIES

            ADT Limited hereby represents and warrants unto each Lender Party
as set forth in this Article III.

            SECTION 3.1.  Organization, etc.  Each of ADT Limited and its
Subsidiaries that is an Obligor or a Material Related Party is a company or
corporation, as the case may be, duly organized and validly existing and, to
the extent applicable, in good standing under the laws of the jurisdiction of
its organization, is duly qualified to do business and is, to the extent
applicable, in good standing as a foreign corporation in each jurisdiction
where the nature of its business requires such qualification and where the
failure to so qualify or be in good standing would reasonably be expected to
have a material adverse effect on the business, results of operations,
financial condition or prospects of ADT Limited and its Subsidiaries taken as
a whole.  Each of ADT Limited and its Subsidiaries that is an Obligor or a
Material Related Party has full power and authority and holds all requisite
governmental licenses, permits and other approvals (i) to own and hold under
lease its property and to conduct its business substantially as currently
conducted by it, except where failure to hold such licenses, permits and other
approvals would not reasonably be expected to have a material adverse effect
on the business, results of operations, financial condition or prospects of
ADT Limited and its Subsidiaries taken as a whole and (ii) to enter into and
perform its obligations under each Loan Document, if any, to which it is a
party.

            SECTION 3.2.  Due Authorization, Non-Contravention, etc.  The
execution, delivery and performance by ADT Limited of this Guaranty and each
other Loan Document executed or to be executed by it, and the execution,
delivery and performance by each other Obligor of each Loan Document executed
or to be executed by it, are within ADT Limited's and each such Obligor's
corporate powers, have been duly authorized by all necessary corporate action,
and do not

                  (a)  contravene ADT Limited's or any such Obligor's Organic
            Documents;

                  (b)  contravene any contractual restriction, law or
            governmental regulation or court decree or order binding on or
            affecting ADT Limited or any such Obligor (including the Companies
            Act 1981 of Bermuda) in any manner that could reasonably be
            expected (i) to have a material adverse effect on the business,
            results of operations, financial condition or prospects of ADT
            Limited and its Subsidiaries taken as a whole, (ii) to impair the
            ability of any Lender, Issuer or Agent to enforce the Obligations
            or (iii) to subject any Lender, Issuer or Agent to any liability;
            or

                  (c)  result in, or require the creation or imposition of,
            any Lien on any of ADT Limited's or any Obligor's properties.

            SECTION 3.3.  Government Approval, Regulation, etc.  No
authorization or approval or other action by, and no notice to or filing with,
any governmental authority or regulatory body or other Person is required for
the due execution, delivery or performance by ADT Limited or any other Obligor
of this Guaranty or any other Loan Document to which it is a party.  Neither
ADT Limited nor any other Obligor is an "investment company" within the
meaning of the Investment Company Act of 1940, as amended, or a "holding
company", or a "subsidiary company" of a "holding company", or an "affiliate"
of a "holding company" or of a "subsidiary company" of a "holding company",
within the meaning of the Public Utility Holding Company Act of 1935, as
amended.

            SECTION 3.4.  Validity, etc.  This Guaranty constitutes, and each
other Loan Document executed by ADT Limited will, on the due execution and
delivery thereof, constitute, the legal, valid and binding obligations of ADT
Limited enforceable in accordance with their respective terms, subject to
applicable bankruptcy, insolvency, reorganization, moratorium or similar laws
from time to time in effect affecting creditors' rights generally and to
general principles of equity; and each Loan Document executed pursuant hereto
by each other Obligor will, on the due execution and delivery thereof by such
Obligor, be the legal, valid and binding obligation of such Obligor enforceable
in accordance with its terms, subject to applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws from time to time in effect
affecting creditors' rights generally and to general principles of equity.

            SECTION 3.5.  Financial Information.  The financial statements set
forth in the 10-K of ADT Limited for the 1995 Fiscal Year and in the 10-Qs of
ADT Limited for the first three Fiscal Quarters of the 1996 Fiscal Year and
all financial statements of ADT Limited and its Subsidiaries furnished to the
Agent and the Lenders pursuant to clauses (a) and (d) of Section 8.1.1 of the
Credit Agreement have, in each case, been prepared in accordance with GAAP
consistently applied, and present fairly the consolidated financial condition
of the corporations covered thereby, as at the dates thereof, and the results
of their operations for the periods then ended.

            SECTION 3.6.  No Material Adverse Change.  Since December 31,
1995, there has been no material adverse change in the business, results of
operations, financial condition or prospects of ADT Limited and its
Subsidiaries taken as a whole.

            SECTION 3.7.  Litigation, Labor Controversies, etc.  There is no
pending or, to the knowledge of ADT Limited, threatened litigation, action,
proceeding, or labor controversy affecting ADT Limited or any of its
Subsidiaries, or any of their respective properties, businesses, assets or
revenues, which could reasonably be expected to materially adversely affect
the financial condition, results of operations, business or prospects of ADT
Limited and its Subsidiaries, taken as a whole (provided that no representation
is being made with respect to the effect on such financial condition, results
of operations, business or prospects of any litigation, action or proceeding
described in the first two paragraphs under the caption "Certain Litigation
Against the Company" in the Preliminary Proxy Statement of ADT Limited filed
with the Securities and Exchange Commission on January 8, 1997, provided to
the Agent prior to the date hereof, including any amendment to the complaint
referred to therein provided to the Agent prior to the Closing Date relating
to the scheduling of the special meeting of ADT Limited's shareholders
referred to in any such amendment), or which purports to affect the legality,
validity or enforceability of this Guaranty, or any other Loan Document,
except as disclosed in Item 3.7 ("Litigation") of the Disclosure Schedule.

            SECTION 3.8.  Subsidiaries.  ADT Limited has no Subsidiaries,
except those Subsidiaries

                  (a)  which are identified in Item 3.8 ("Existing
            Subsidiaries") of the Disclosure Schedule; or

                  (b)  which are permitted to have been created or acquired in
            accordance with Section 4.2.5 or 4.2.9.

Without limiting any term or provision hereof, to the extent any Person
becomes a Subsidiary of ADT Limited in accordance with (and not in
contravention of) any term or provision hereof or of any other Loan Document,
ADT Limited may supplement such Item 3.8 of the Disclosure Schedule to include
such new Subsidiary by delivering a certificate, signed by an Authorized
Officer, certifying (i) as to the name and place of organization of such new
Subsidiary, (ii) as to the method by which such new Subsidiary was created and
(iii) that such new Subsidiary was created without contravening any term or
provision hereof or of any other Loan Document.

            SECTION 3.9.  Ownership of Properties.  ADT Limited and each of
its Subsidiaries owns good and marketable title to, or valid leases of, all of
its properties and assets necessary to conduct its business substantially as
currently conducted by it.

            SECTION 3.10.  Taxes.  ADT Limited and each of its Subsidiaries,
and each other Obligor, has filed all material tax returns and reports required
by law to have been filed by it and has paid all material taxes and
governmental charges thereby shown to be owing, except any such taxes or
charges which are being diligently contested in good faith by appropriate
proceedings and for which adequate reserves in accordance with GAAP shall have
been set aside on its books.

            SECTION 3.11.  Pension and Welfare Plans.  During the
twelve-consecutive-month period prior to the date of the execution and
delivery of the Credit Agreement and prior to the date of any Credit Extension
thereunder, no steps have been taken to terminate any Pension Plan which
termination could result in the incurrence by ADT Limited or any member of the
Controlled Group of any material liability, and no contribution failure has
occurred with respect to any Pension Plan sufficient to give rise to a Lien
under section 302(f) of ERISA.  No condition exists or event or transaction
has occurred with respect to any Pension Plan which might result in the
incurrence by ADT Limited or any member of the Controlled Group of any
material liability, fine or penalty.  Except as disclosed in Item 3.11
("Employee Benefit Plans") of the Disclosure Schedule, neither ADT Limited nor
any member of the Controlled Group has any material contingent liability with
respect to any post-retirement benefit under a Welfare Plan, other than
liability for continuation coverage described in Part 6 of Title I of ERISA.

            SECTION 3.12.  Environmental Warranties.  Except as set forth in
Item 3.12 ("Environmental Matters") of the Disclosure Schedule,

            Subsidiaries have been, and continue to be, owned or leased by ADT
            Limited and its Subsidiaries in material compliance with all
            Environmental Laws;

                  (b)  there have been no past, and there are no pending or

                  information received by ADT Limited or any of its
                  Subsidiaries with respect to any alleged violation of any
                  Environmental Law, which could reasonably be expected to
                  have a material adverse effect on the business, results of
                  operations, financial condition or prospects of ADT Limited
                  and its Subsidiaries or the Borrower and its Subsidiaries, or

                        (ii)  complaints, notices or inquiries to ADT Limited
                  or any of its Subsidiaries regarding potential liability
                  under any Environmental Law, which could reasonably be
                  expected to have a material adverse effect on the business,
                  results of operations, financial condition or prospects of
                  ADT Limited and its Subsidiaries or the Borrower and its

            aggregate, have, or may reasonably be expected to have, a material
            adverse effect on the business, results of operations, financial
            condition or prospects of ADT Limited and its Subsidiaries or the
            Borrower and its Subsidiaries;

            are in compliance with all permits, certificates, approvals,
            licenses and other authorizations relating to environmental

            failure to have been issued any such permit, certificate,
            approval, license or other authorization or to have complied with
            any of the foregoing would not, singly or in the aggregate,
            reasonably be expected to have a material adverse effect on the
            business, results of operations, financial condition or prospects
            of ADT Limited and its Subsidiaries or the Borrower and its
            Subsidiaries;

            CERCLA;

            injury, including claims under CERCLA;

                  (h)  there are no polychlorinated biphenyls or friable

            material adverse effect on the business, results of operations,
            financial condition or prospects of ADT Limited and its

            each jurisdiction where the nature of its business or the location
            of its assets requires it to be so qualified, except to the extent
            the failure to maintain and preserve its corporate existence or to

            financial condition or prospects of ADT Limited and its
            Subsidiaries (it being acknowledged that the failure of ADT
            Limited or the Borrower to maintain and preserve its corporate
            existence (except as permitted under Section 4.2.9) shall be
            deemed to have such a material adverse effect); and

            material taxes, assessments and governmental charges imposed upon
            it or upon its property except to the extent being diligently

carried on in connection therewith may be properly conducted at all times
unless ADT Limited determines in good faith that the continued maintenance of
any of its properties is no longer economically desirable.

            SECTION 4.1.3.  Insurance.  ADT Limited will, and will cause each
of its Subsidiaries to, maintain or cause to be maintained with responsible

any of its representatives, at reasonable times and intervals (but not more

occurred and be continuing (in which case, and during such period, each Lender
shall have the rights of the Agent under this Section)) to visit all of its
offices, to discuss its financial matters with its officers and independent
public accountant (provided a representative of ADT Limited or such Subsidiary
is given prior notice of, and the opportunity to be present during, such
discussion) and, subject to appropriate agreements of confidentiality and to
any restrictions imposed under applicable law (including regulations
promulgated by the  United States Department of Defense), to examine any of
its books or other corporate records.  ADT Limited shall pay any fees of such
independent public accountant incurred in connection with the Agent's or any
Lender's exercise of its rights pursuant to this Section.  In addition, ADT

            material compliance with all Environmental Laws, apply for and
            keep all necessary permits, approvals, certificates, licenses and
            other authorizations relating to environmental matters in effect
            where the failure to so keep in effect could reasonably be
            expected to have a material adverse effect on the business,
            results of operations, financial condition or prospects of ADT
            Limited and its Subsidiaries or the Borrower and its Subsidiaries
            and remain in material compliance therewith, and handle all

            relating to the condition of its facilities and properties or
            compliance with Environmental Laws, which claims or other alleged
            conditions could reasonably be expected to have a material adverse
            effect on the business, results of operations, financial condition
            or prospects of ADT Limited and its Subsidiaries or the Borrower
            and its Subsidiaries; and

                  (c)  provide such information and certifications which the

event any Person becomes a Material Subsidiary, notify the Agent of such event
or condition and will cause such new Material Subsidiary to execute and
deliver to the Agent as soon as practicable (but in no event later than thirty
days after the occurrence of such event or condition) a Subsidiary Guarantor
Guaranty Supplement, together with such certificates and legal opinions as the
Agent may reasonably request.

            SECTION 4.1.7.  Maintenance of Adequate Guarantees.  If at any time
the Subsidiary Guarantors subject to the obligations of the Subsidiary
Guarantor Guaranty do not account on a consolidated basis for at least 90% of
the consolidated gross revenues of the Borrower and its Subsidiaries and at
least 90% of the consolidated gross assets of the Borrower and its Subsidiaries

necessary to meet the 90% Test to execute and deliver to the Agent as soon as
practicable (but in no event later than thirty days after the occurrence of
such event or condition) a Subsidiary Guarantor Guaranty Supplement, together
with such certificates and legal opinions as the Agent may reasonably request.

            with the terms of the Articles of Incorporation of ADT Finance
            Inc. as in effect on the Existing Credit Facility Effective Date)
            shall be permitted if an Event of Default (including a default in
            the observance by the Borrower of its obligations under clause (a)
            of Section 8.2.3 of the Credit Agreement) shall have occurred and
            be continuing or would occur upon giving effect to such Restricted
            Distribution; and

                  (y)  no Restricted Distribution otherwise permitted pursuant
            to this Section 4.2.6(a) shall be permitted if such Restricted
            Distribution would, pursuant to the terms of the Senior Note
            Indenture, decrease the Restricted Payment Basket Amount to an
            amount which is less than the excess of (1) the sum of (A) the
            aggregate amount expended on Permitted Business Acquisitions
            (other than the ASH Transaction to the extent the aggregate
            consideration therefor did not exceed $425,000,000) after the
            Existing Credit Facility Effective Date in excess of the
            applicable Annual Limits (or, during the effectiveness of the
            Existing Credit Facility, the applicable Annual Limits (as defined
            under the Existing Credit Facility)) and (B) the aggregate amount
            of Capital Expenditures made after the Existing Credit Facility
            Effective Date with the cash proceeds referred to in clause (a) of
            the definition of Equity Proceeds Amount and designated as such
            pursuant to the Compliance Certificate (including any compliance
            certificate delivered under the Existing Credit Facility)
            delivered in connection with the Fiscal Quarter in which such
            Capital Expenditures were paid over (2) the portion (if any) of
            such sum which resulted in a decrease of the Restricted Payment
            Basket Amount.

            (b)  ADT Limited will not, and will not permit any of its
Subsidiaries to, directly or indirectly,

                  (i)  declare or pay any dividend on, or make any
            distribution to holders of, any shares of Capital Stock of the
            Borrower (other than (A) dividends or distributions payable in
            shares of Capital Stock of the Borrower or in rights, warrants or
            options to purchase such Capital Stock, but excluding dividends or
            distributions payable in Redeemable Capital Stock or in options,
            warrants or other rights to purchase Redeemable Capital Stock,
            provided that dividends on Redeemable Capital Stock may be paid in
            shares of such Redeemable Capital Stock and (B) the dividend of
            the Dividended Note), or

                  (ii)  purchase, redeem, retire or otherwise acquire for
            value, or make any payment on account of the purchase, redemption,
            retirement or other acquisition for value of, any Capital Stock of
            the Borrower or any warrants, rights or options to purchase or
            acquire any such Capital Stock

(such payments or any other actions described in (but not excluded from) the
foregoing clauses (i) and (ii) being herein referred to as "Restricted Borrower
Distributions"), unless the amount of such Restricted Borrower Distribution
(which amount, in the case of a Restricted Borrower Distribution to be made
in property, shall equal the Fair Market Value thereof (as determined, in the
case of any property with an aggregate value in excess of $15,000,000, in good
faith by the Board of Directors of the Borrower, whose determination shall be
evidenced by a certified written resolution of such Board)), when added to the
aggregate amount of all such Restricted Borrower Distributions declared since
the Existing Credit Facility Effective Date, would not exceed 50% of the
aggregate Net Income of the Borrower accrued on a cumulative basis during the
period (taken as one accounting period) from the Existing Credit Facility
Effective Date to the last day of the most recently completed Fiscal Quarter
with respect to which, pursuant to Section 8.1.1(a) or 8.1.1(d) of the Credit
Agreement (or Section 8.1.1(d) of the Existing Credit Facility), financial
statements have been delivered to the Agent on or prior to the date of the
proposed Restricted Borrower Distribution; provided, however, that no
Restricted Borrower Distribution otherwise permitted pursuant to this Section
4.2.6(b) shall be permitted if an Event of Default (including a default in the
observance by the Borrower of its obligations under clause (a) of Section
8.2.3 of the Credit Agreement) shall have occurred and be continuing or would
occur upon giving effect to such Restricted Borrower Distribution.

            (c)  ADT Limited will not, and will not permit any of its
Subsidiaries to, directly or indirectly,

                  (i)  make any payment of interest on the Senior Notes or any
            Subordinated Debt (other than Subordinated Debt originally issued
            to ADT Limited or a Wholly Owned Subsidiary of ADT Limited (or
            otherwise acquired by ADT Limited or such Wholly-Owned Subsidiary,
            to the extent that the consideration paid by ADT Limited or a
            Wholly-Owned Subsidiary resulted in a decrease of the Restricted
            Payment Basket Amount) and held by ADT Limited or a Wholly Owned
            Subsidiary of ADT Limited) on any day other than the date such
            payment is required to be made as set forth in the Senior Notes,
            the Senior Note Indenture, the Senior Subordinated Note Indenture,
            the LYONs, the LYONs Indenture or the other documents and
            instruments memorializing such Subordinated Debt, or which, in the
            case of any Subordinated Debt (including Subordinated Debt held by
            ADT Limited or a Wholly Owned Subsidiary of ADT Limited), would
            violate the subordination provisions thereof; or

                  (ii)  make any payment or prepayment of principal of, or
            redeem, purchase, repurchase or defease, the Senior Notes or any
            Subordinated Debt (other than Subordinated Debt originally issued
            to ADT Limited or a Wholly Owned Subsidiary of ADT Limited (or
            otherwise acquired by ADT Limited or such Wholly-Owned Subsidiary,
            to the extent that the consideration paid by ADT Limited or such
            Wholly-Owned Subsidiary resulted in a decrease of the Restricted
            Payment Basket Amount) and held by ADT Limited or a Wholly Owned
            Subsidiary of ADT Limited, except, prior to the occurrence of a
            Permitted Auction Business Sale, Subordinated Debt in respect of
            the Dividended Note) on any day other than the date any such
            payment, prepayment, redemption or repurchase is required to be
            made as set forth in Sections 1010 and 1016 of the Senior Note
            Indenture, Sections 1010 and 1016 of the Senior Subordinated Note
            Indenture, Section 3.09 of the LYONs Indenture or in the other
            documents and instruments memorializing the Senior Notes or such
            Subordinated Debt, or which, in the case of any Subordinated Debt
            (including Subordinated Debt held by ADT Limited or a Wholly Owned
            Subsidiary of ADT Limited), would violate the subordination
            provisions thereof; provided, however, that ADT Limited and its
            Subsidiaries may, to the extent the subordination provisions of
            the Senior Subordinated Note Indenture, the LYONs Indenture or any
            other document or instrument memorializing Subordinated Debt would
            not be violated thereby, make any payment or prepayment of
            principal of, or redeem or repurchase, the Senior Notes or any
            Subordinated Debt if permitted by the terms of the Senior Note
            Indenture; provided further, however, that no payment, prepayment,
            redemption or repurchase otherwise permitted pursuant to the
            immediately preceding proviso shall be permitted if (x) an Event of
            Default shall have occurred and be continuing or would occur upon
            giving effect to such payment, prepayment, redemption or repurchase
            or (y) such payment, prepayment, redemption or repurchase would,
            pursuant to the terms of the Senior Note Indenture, decrease the
            Restricted Payment Basket Amount to an amount which is less than
            the excess of (1) the sum of (A) the aggregate amount expended on
            Permitted Business Acquisitions (other than the ASH Transaction to
            the extent the aggregate consideration therefor did not exceed
            $425,000,000) after the Existing Credit Facility Effective Date in
            excess of the applicable Annual Limits (or, during the
            effectiveness of the Existing Credit Facility, the applicable
            Annual Limits (as defined under the Existing Credit Facility)) and
            (B) the aggregate amount of Capital Expenditures made after the
            Existing Credit Facility Effective Date with the cash proceeds
            referred to in clause (a) of the definition of Equity Proceeds
            Amount and designated as such pursuant to the Compliance
            Certificate (including any compliance certificate delivered under
            the Existing Credit Facility) delivered in connection with the
            Fiscal Quarter in which such Capital Expenditures were paid over
            (2) the portion (if any) of such aggregate amount which resulted
            in a decrease of the Restricted Payment Basket Amount.

            SECTION 4.2.7.  Capital Expenditures, etc.  ADT Limited will not,
and will not permit any of its Subsidiaries to, make Capital Expenditures,
except (i) Capital Expenditures in connection with conducting the Core

no Capitalized Lease Liabilities otherwise permitted to be incurred pursuant
to this Section shall be permitted to be incurred if the aggregate amount of
all such Capitalized Lease Liabilities incurred during any Fiscal Year would
exceed $30,000,000.

            SECTION 4.2.8.  [Intentionally Omitted.]

            SECTION 4.2.9.  Consolidation, Merger, etc.  ADT Limited will not,
and will not permit any of its Subsidiaries to, liquidate or dissolve, or
amalgamate or consolidate with, or merge into or with, any other Person, or
otherwise enter into or consummate any Business Acquisition not constituting
an Investment, except

                  (a)  any Subsidiary of ADT Limited that is a direct or
            indirect parent of the Borrower may liquidate or dissolve
            voluntarily into, and may amalgamate or consolidate with or merge
            into, ADT Limited or any Wholly Owned Subsidiary of ADT Limited

                                  ARTICLE II

                              GUARANTY PROVISIONS

            SECTION 2.1.  Guaranty.  Each Subsidiary Guarantor hereby
absolutely, unconditionally and irrevocably, jointly and severally,

                  (a)  guarantees the full and punctual payment when due,
            whether at stated maturity, by required prepayment, declaration,
            acceleration, demand or otherwise, of all Obligations of the
            Borrower and each other Obligor now or hereafter existing, whether
            for principal, interest, Reimbursement Obligations, fees, expenses
            or otherwise (including all such amounts which would become due
            but for the operation of the automatic stay under Section 362(a)
            of the United States Bankruptcy Code, 11 U.S.C. Section 362(a),
            and the operation of Sections 502(b) and 506(b) of the United
            States Bankruptcy Code, 11 U.S.C. Section 502(b) and Section
            506(b)); and

                  (b)  indemnifies and holds harmless each Lender Party and
            each holder of a Note for any and all costs and expenses (including
            reasonable attorney's fees and expenses) incurred by such Lender
            Party or such holder, as the case may be, in enforcing any rights
            under this Guaranty;

provided, however, that each Subsidiary Guarantor shall be liable under this
Guaranty for the maximum amount of such liability that can be hereby incurred
without rendering this Guaranty, as it relates to such Subsidiary Guarantor,
voidable under applicable law relating to fraudulent conveyance or fraudulent
transfer, and not for any greater amount.  This Guaranty constitutes a
guaranty of payment when due and not of collection, and each Subsidiary
Guarantor specifically agrees that it shall not be necessary or required that
any Lender Party or any holder of any Note exercise any right, assert any
claim or demand or enforce any remedy whatsoever against the Borrower or any
other Obligor (or any other Person) before or as a condition to the
obligations of such Subsidiary Guarantor hereunder.

            SECTION 2.2.  Guaranty Absolute, etc.  This Guaranty shall in all
respects be a continuing, absolute, unconditional and irrevocable guaranty of
payment, and shall remain in full force and effect until all Obligations of the
Borrower and each other Obligor have been paid in full, all obligations of each
Subsidiary Guarantor hereunder shall have been paid in full and all
Commitments shall have terminated.  Each Subsidiary Guarantor guarantees that
the Obligations of the Borrower and each other Obligor and their respective
Subsidiaries will be paid strictly in accordance with the terms of the Credit
Agreement and each other Loan Document under which they arise, without regard
(to the fullest extent permitted under applicable law) to any law, regulation
or order now or hereafter in effect in any jurisdiction affecting any of such
terms or the rights of any Lender Party or any holder of any Note with respect
thereto (and each Subsidiary Guarantor hereby waives to the fullest extent it
may do so any right or rights it may have under any such law, regulation or
order).  Without limiting the generality of the foregoing, the liability of
each Subsidiary Guarantor under this Guaranty shall be absolute, unconditional
and irrevocable irrespective of:

                  (a)  any lack of genuineness, validity, legality or
            enforceability of the Credit Agreement or any other Loan Document
            (other than, in respect of such Subsidiary Guarantor, this
            Guaranty) or of any of the Obligations (other than the Obligations
            of such Subsidiary Guarantor hereunder);

                  (b)  the failure of any Lender Party or any holder of any
            Note

                        (i)  to assert any claim or demand or to enforce any
                  right or remedy against the Borrower, any other Obligor or
                  any other Person (including any other Subsidiary Guarantor)
                  under the provisions of the Credit Agreement or any other
                  Loan Document or otherwise, or

                        (ii)  to exercise any right or remedy against any other
                  guarantor (including any other Subsidiary Guarantor) of, or
                  collateral securing, any Obligations of the Borrower or any
                  other Obligor;

                  (c)  any change in the time, manner or place of payment of,
            or in any other term of, all or any of the Obligations of the
            Borrower or any other Obligor (other than such Subsidiary
            Guarantor), or any other extension, compromise or renewal of any
            Obligation of the Borrower or any other Obligor (other than such
            Subsidiary Guarantor);

                  (d)  any reduction, limitation, impairment or termination of
            the Obligations of the Borrower or any other Obligor (other than
            such Subsidiary Guarantor) for any reason, including any claim of
            waiver, release, surrender, alteration or compromise, and shall
            not be subject to (and each Subsidiary Guarantor hereby waives any
            right to or claim of) any defense or setoff, counterclaim,
            recoupment or termination whatsoever by reason of the invalidity,
            illegality, nongenuineness, irregularity, compromise,
            unenforceability of, or any other event or occurrence affecting,
            the Obligations of the Borrower, any other Obligor (other than
            such Subsidiary Guarantor) or otherwise;

                  (e)  any amendment to, rescission, waiver, or other
            modification of, or any consent to departure from, any of the
            terms of the Credit Agreement or any other Loan Document (other
            than, in respect of such Subsidiary Guarantor, this Guaranty);

                  (f)  any addition, exchange, release, surrender or
            non-perfection of any collateral, or any amendment to or waiver or
            release of or addition to, or consent to departure from, any other
            guaranty (including the ADT Limited Guaranty), held by any Lender
            Party or any holder of any Note securing any of the Obligations of
            the Borrower or any other Obligor; or

                  (g)  any other circumstances which might otherwise
            constitute a defense available to, or a legal or equitable
            discharge of, the Borrower, any other Obligor, any surety or any
            other guarantor (or any other Guarantor).

            SECTION 2.3.  Stay of Acceleration, Reinstatement, etc.  Each
Subsidiary Guarantor agrees that, if acceleration of the time for payment of
any amount payable by the Borrower under the Credit Agreement, the Notes or
any other Loan Document or of compliance by the Borrower with its obligations
under Section 4.7 of the Credit Agreement is, in either case, stayed upon the
occurrence with respect to the Borrower of any Event of Default described in
clause (b) or (d) of Section 9.1.9 of the Credit Agreement, all such amounts
and obligations otherwise subject to acceleration or compliance under the
terms of the Credit Agreement shall nonetheless be payable and performed by
such Subsidiary Guarantor hereunder forthwith on demand by the Agent made at
the request of the requisite proportion of the Lenders specified in Section
9.3 of the Credit Agreement.  Each Subsidiary Guarantor agrees that this
Guaranty shall continue to be effective or be reinstated, as the case may be,
if at any time any payment (in whole or in part) of any of the Obligations is
rescinded or must otherwise be restored by any Lender Party or any holder of
any Note, upon the insolvency, bankruptcy or reorganization of the Borrower,
any other Obligor (other than such Subsidiary Guarantor) or otherwise, all as
though such payment had not been made.

            SECTION 2.4.  Waiver, etc.  Each Subsidiary Guarantor hereby
waives promptness, diligence, notice of acceptance and any other notice with
respect to any of the Obligations of the Borrower or any other Obligor and this
Guaranty and any requirement that the Agent, any other Lender Party or any
holder of any Note protect, secure, perfect or insure any security interest or
Lien, or any property subject thereto, or exhaust any right or take any action
against the Borrower, any other Obligor or any other Person (including any
other guarantor and any other Guarantor) or entity or any collateral securing
the Obligations of the Borrower or any other Obligor, as the case may be.

            SECTION 2.5.  Subrogation.  Each Subsidiary Guarantor hereby
agrees that it will not exercise any rights which it may now or hereafter
acquire against the Borrower or any other Obligor that arise from the
existence, payment, performance or enforcement of such Subsidiary Guarantor's
obligations under this Guaranty or any other Loan Document, including any
right of subrogation, reimbursement, exoneration, or indemnification, any
right to participate in any claim or remedy of the Lender Parties against the
Borrower or any other Obligor or any collateral which the Agent now has or
hereafter acquires, whether or not such claim, remedy or right arises in
equity, or under contract, statute or common law, including the right to take
or receive from the Borrower or any other Obligor, directly or indirectly, in
cash or other property or by set-off or in any manner, payment or security on
account of such claim or other rights, until the Obligations have been paid in
full in cash and the Commitments have been terminated.  If any amount shall be
paid to such Subsidiary Guarantor in violation of the preceding sentence and
the Obligations shall not have been paid in cash in full and the Commitments
have not been terminated, such amount shall be deemed to have been paid to
such Subsidiary Guarantor for the benefit of, and held in trust for, the
Lender Parties, and shall forthwith be paid to the Lender Parties to be
credited and applied upon the Obligations, whether matured or unmatured.  Each
Subsidiary Guarantor acknowledges that it will receive direct and indirect
benefits from the financing arrangements contemplated by the Credit Agreement
and that the agreement set forth in this Section is knowingly made in
contemplation of such benefits.

            SECTION 2.6.  Successors, Transferees and Assigns; Transfers of
Notes, etc.  This Guaranty shall:

                  (a)  be binding upon each Subsidiary Guarantor and its
            successors, transferees and assigns; and

                  (b)  inure to the benefit of and be enforceable by the Agent
            and each other Lender Party.

Without limiting the generality of clause (b), any Lender may assign or
otherwise transfer (in whole or in part) any Note or Loan held by it to any
other Person or entity, and such other Person or entity shall thereupon become
vested with all rights and benefits in respect thereof granted to such Lender
under any Loan Document (including this Guaranty) or otherwise, subject,
however, to the provisions of Section 11.11 and Article X of the Credit
Agreement.

            SECTION 2.7.  Payments Free and Clear of Taxes, etc.  Each
Subsidiary Guarantor hereby agrees that:

                  (a)  Any and all payments made by such Subsidiary Guarantor
            hereunder shall be made in accordance with Section 5.6 of the
            Credit Agreement free and clear of, and without deduction for, any
            and all present or future taxes, levies, imposts, deductions,
            charges or withholdings, and all liabilities with respect thereto,
            excluding, in the case of each Lender Party or any holder of a
            Note, taxes imposed on its net income and franchise taxes imposed
            on it (such non-excluded items being hereinafter referred to as
            "Taxes").  If any such Subsidiary Guarantor shall be required by
            law to deduct any Taxes from or in respect of any sum payable
            hereunder to any Lender Party or any holder of a Note

                        (i)  the sum payable shall be increased as may be
                  necessary so that after making all required deductions
                  (including deductions applicable to additional sums payable
                  under this Section) such Lender Party or such holder, as the
                  case may be, receives an amount equal to the sum it would
                  have received had no such deductions been made,

                        (ii)  such Subsidiary Guarantor shall make such
                  deductions, and

                        (iii)  such Subsidiary Guarantor shall pay the full
                  amount deducted to the relevant taxation authority or other
                  authority in accordance with applicable law.

                  (b)  Such Subsidiary Guarantor shall pay any present or
            future stamp or documentary taxes or any other excise or property
            taxes, charges or similar levies which arise from any payment made
            hereunder or from the execution, delivery or registration of, or
            otherwise with respect to, this Guaranty (hereinafter referred to
            as "Other Taxes").

                  (c)  Such Subsidiary Guarantor hereby indemnifies and holds
            harmless each Lender Party and each of holder of a Note for the
            full amount of Taxes or Other Taxes (including, without
            limitation, any Taxes or Other Taxes imposed by any jurisdiction
            on amounts payable under this Section) paid by such Lender Party
            or such holder, as the case may be, and any liability (including
            penalties, interest and expenses) arising therefrom or with
            respect thereto, whether or not such Taxes or Other Taxes were
            correctly or legally asserted.

                  (d)  Without prejudice to the survival of any other
            agreement of such Subsidiary Guarantor hereunder, the agreements
            and obligations of such Subsidiary Guarantor contained in this
            Section 2.7 shall survive the payment in full of the principal of
            and interest on the Loans.


                                  ARTICLE III

                        REPRESENTATIONS AND WARRANTIES

            SECTION 3.1.  Representations and Warranties.  Each Subsidiary
Guarantor hereby represents and warrants for itself unto each Lender Party as
to all matters contained in Article VII of the Credit Agreement and Article III
of the ADT Limited Guaranty, in each case insofar as applicable to such
Subsidiary Guarantor or such Subsidiary Guarantor's properties, together with
all related definitions and ancillary provisions, all of which are hereby
incorporated into this Section 3.1 as those specifically set forth herein.  In
addition, each Subsidiary Guarantor hereby represents and warrants for itself
unto each Lender Party as further set forth in this Article III.

            SECTION 3.1.1.  Organization, etc.  Such Subsidiary Guarantor and
each of its Subsidiaries is a corporation duly organized and validly existing
and in good standing under the laws of the State of its incorporation, is duly
qualified to do business and is in good standing as a foreign corporation in
each jurisdiction where the nature of its business or the location of its
assets requires such qualification and where the failure to so qualify or be
in good standing would reasonably be expected to have a material adverse
effect on the business, results of operations, financial condition or
prospects of the Borrower and its Subsidiaries taken as a whole.  Such
Subsidiary Guarantor and each of its Subsidiaries has full power and authority
and holds all requisite governmental licenses, permits and other approvals (i)
to own and hold under lease its property and to conduct its business
substantially as currently conducted by it, except where failure to hold such
licenses, permits and other approvals would not reasonably be expected to have
a material adverse effect on the business, results of operations, financial
condition or prospects of the Borrower and its Subsidiaries taken as a whole
and (ii) to enter into and perform its obligations under this Guaranty and
each other Loan Document to which it is a party.


            SECTION 3.1.2.  Due Authorization, Non-Contravention, etc.  The
execution, delivery and performance by such Subsidiary Guarantor of this
Guaranty and each other Loan Document executed or to be executed by it and
such Subsidiary Guarantor's participation in the consummation of the
Transaction are within such Subsidiary Guarantor's corporate powers, have been
duly authorized by all necessary corporate action, and do not

                  (a)  contravene such Subsidiary Guarantor's Organic
            Documents;

                  (b)  contravene any contractual restriction, law or
            governmental regulation or court decree or order binding on or
            affecting such Subsidiary Guarantor in any manner that could
            reasonably be expected (i) to have a material adverse effect on
            the business, results of operations, financial condition or
            prospects of the Borrower and its Subsidiaries taken as a whole,
            (ii) to impair the ability of any Lender, any Issuer or the Agent
            to enforce the Obligations or (iii) to subject any Lender, any
            Issuer or the Agent to any liability; or

                  (c)  result in, or require the creation or imposition of,
            any Lien on any of such Subsidiary Guarantor's properties.

            SECTION 3.1.3.  Government Approval, Regulation, etc.  No
authorization or approval or other action by, and no notice to or filing with,
any governmental authority or regulatory body or other Person is required for
the due execution, delivery or performance by such Subsidiary Guarantor of
this Guaranty or any other Loan Document to which it is a party.  No
Subsidiary Guarantor is an "investment company" within the meaning of the
Investment Company Act of 1940, as amended, or a "holding company", or a
"subsidiary company" of a "holding company", or an "affiliate" of a "holding
company" or of a "subsidiary company" of a "holding company", within the
meaning of the Public Utility Holding Company Act of 1935, as amended.

            SECTION 3.1.4.  Validity, etc.  This Guaranty constitutes, and each
other Loan Document executed by such Subsidiary Guarantor will, on the due
execution and delivery thereof, constitute, the legal, valid and binding
obligations of such Subsidiary Guarantor enforceable in accordance with their
respective terms, subject to applicable bankruptcy, insolvency, reorganization,
moratorium or similar laws from time to time in effect affecting enforceability
of creditors' rights generally and to general principles of equity.


                                  ARTICLE IV

                                COVENANTS, ETC.

            SECTION 4.1.  Affirmative Covenants.  Each Subsidiary Guarantor
covenants and agrees that, until the Covenant Termination Date, such
Subsidiary Guarantor will perform, comply with and be bound by all the
agreements, covenants and obligations contained in Article VIII of the Credit
Agreement and Article IV of the ADT Limited Guaranty applicable to such
Subsidiary Guarantor or such Subsidiary Guarantor's properties.  Each such
agreement, covenant and obligation contained in each such Article and all
related definitions and ancillary provisions are hereby incorporated into this
Guaranty as though specifically set forth herein.


                                   ARTICLE V

                           MISCELLANEOUS PROVISIONS

            SECTION 5.1.  Loan Document.  This Guaranty is a Loan Document
executed pursuant to the Credit Agreement and shall (unless otherwise

limitation, Article XI thereof.

            SECTION 5.2.  Binding on Successors, Transferees and Assigns;
Assignment.  In addition to, and not in limitation of, Section 2.6, this
Guaranty shall be binding upon each Subsidiary Guarantor and its successors,
transferees and assigns and shall inure to the benefit of and be enforceable by
each Lender Party and each holder of a Note and their respective successors,
transferees and assigns (to the full extent provided pursuant to Section 2.6);
provided, however, that no Subsidiary Guarantor may assign any of its
obligations hereunder without the prior written consent of all Lenders.

            SECTION 5.3.  Amendments, etc.  No amendment to or waiver of any
provision of this Guaranty, nor consent to any departure by any Subsidiary
Guarantor herefrom, shall in any event be effective unless the same shall be in
writing and signed by each Subsidiary Guarantor and the Agent, and then such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given.

            SECTION 5.4.  Addresses for Notices to the Subsidiary Guarantor.
All notices and other communications hereunder to any Subsidiary Guarantor
shall be in writing or by facsimile and addressed, delivered or transmitted to
it in care of the Borrower at the address and facsimile number and in the
manner provided for in Section 11.2 of the Credit Agreement.

            SECTION 5.5.  No Waiver; Remedies.  In addition to, and not in
limitation of, Section 2.2 and Section 2.4, no failure on the part of any
Lender Party or any holder of a Note to exercise, and no delay in exercising,
any right hereunder shall operate as a waiver thereof; nor shall any single or
partial exercise of any right hereunder preclude any other or further exercise
thereof or the exercise of any other right.  The remedies herein provided are
cumulative and not exclusive of any remedies provided by law.

            SECTION 5.6.  Headings.  The various headings used in this Guaranty
are for convenience of reference only and shall not affect the construction of
this Guaranty.

            SECTION 5.7.  Setoff.  In addition to, and not in limitation of,
any rights of any Lender Party or any holder of a Note under applicable law,
each Lender Party and each such holder shall,  upon the occurrence of any
Event of Default, to the fullest extent permitted under applicable law, have
the right to appropriate and apply to the payment of the obligations of any
Subsidiary Guarantor owing to it hereunder, whether or not then due, any and
all balances, credits, deposits, accounts or moneys of such Subsidiary
Guarantor then or thereafter maintained with such Lender Party or such holder;
provided, however, that any such appropriation and application shall be
subject to the provisions of Section 5.8 of the Credit Agreement.

            SECTION 5.8.  Severability.  Wherever possible, each provision of
this Guaranty shall be interpreted in such manner as to be effective and valid
under applicable law, but if any provision of this Guaranty shall be
prohibited by or invalid under such law, such provision shall be ineffective to
the extent of such prohibition or invalidity, without invalidating the
remainder of such provision or the remaining provisions of this Guaranty.

            SECTION 5.9.   Execution in Counterparts.  This Guaranty may be
executed by the parties hereto in several counterparts, each of which shall be
deemed to be an original and all of which shall constitute together but one and
the same agreement.

            SECTION 5.10.  Governing Law; Entire Agreement.  THIS GUARANTY
SHALL BE DEEMED TO BE A CONTRACT MADE UNDER AND GOVERNED BY THE INTERNAL LAWS
OF THE STATE OF NEW YORK.  THIS GUARANTY AND THE OTHER LOAN DOCUMENTS
CONSTITUTE THE ENTIRE UNDERSTANDING AMONG THE PARTIES HERETO WITH RESPECT TO
THE SUBJECT MATTER HEREOF AND SUPERSEDE ANY PRIOR AGREEMENTS, WRITTEN OR ORAL,
WITH RESPECT THERETO.

            SECTION 5.11.  Forum Selection and Consent to Jurisdiction.  ANY
LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS
GUARANTY, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER
ORAL OR WRITTEN) OR ACTIONS OF THE LENDER PARTIES OR ANY SUBSIDIARY GUARANTOR
SHALL BE BROUGHT AND MAINTAINED TO THE FULLEST EXTENT PERMITTED BY APPLICABLE
LAW EXCLUSIVELY IN THE COURTS OF THE STATE OF NEW YORK OR IN THE UNITED STATES
DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK; PROVIDED, HOWEVER, THAT
ANY SUIT SEEKING ENFORCEMENT AGAINST ANY COLLATERAL OR OTHER PROPERTY MAY BE
BROUGHT, AT THE AGENT'S OPTION, IN THE COURTS OF ANY JURISDICTION WHERE SUCH
COLLATERAL OR OTHER PROPERTY MAY BE FOUND.  EACH SUBSIDIARY GUARANTOR HEREBY
EXPRESSLY AND IRREVOCABLY SUBMITS TO THE JURISDICTION OF THE COURTS OF THE
STATE OF NEW YORK AND OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN
DISTRICT OF NEW YORK FOR THE PURPOSE OF ANY SUCH LITIGATION AS SET FORTH ABOVE
AND IRREVOCABLY AGREES TO BE BOUND BY ANY JUDGMENT RENDERED THEREBY IN
CONNECTION WITH SUCH LITIGATION.  EACH SUBSIDIARY GUARANTOR FURTHER
IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS BY REGISTERED MAIL, POSTAGE
PREPAID, OR BY PERSONAL SERVICE WITHIN OR WITHOUT THE STATE OF NEW YORK.  EACH
SUBSIDIARY GUARANTOR HEREBY EXPRESSLY AND IRREVOCABLY WAIVES, TO THE FULLEST
EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY HAVE OR HEREAFTER MAY HAVE
TO THE LAYING OF VENUE OF ANY SUCH LITIGATION BROUGHT IN ANY SUCH COURT
REFERRED TO ABOVE AND ANY CLAIM THAT ANY SUCH LITIGATION HAS BEEN BROUGHT IN
AN INCONVENIENT FORUM.  TO THE EXTENT THAT ANY SUBSIDIARY GUARANTOR HAS OR
HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM JURISDICTION OF ANY COURT OR FROM ANY
LEGAL PROCESS (WHETHER THROUGH SERVICE OR NOTICE, ATTACHMENT PRIOR TO
JUDGMENT, ATTACHMENT IN AID OF EXECUTION OR OTHERWISE) WITH RESPECT TO ITSELF
OR ITS PROPERTY, SUCH SUBSIDIARY GUARANTOR HEREBY IRREVOCABLY WAIVES TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW SUCH IMMUNITY IN RESPECT OF ITS
OBLIGATIONS UNDER THIS GUARANTY.

            SECTION 5.12.  Waiver of Jury Trial.  THE LENDER PARTIES AND EACH
SUBSIDIARY GUARANTOR HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY
RIGHTS THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED
HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS GUARANTY, OR ANY
COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR
ACTIONS OF THE LENDER PARTIES OR ANY SUBSIDIARY GUARANTOR.  EACH SUBSIDIARY
GUARANTOR ACKNOWLEDGES AND AGREES THAT IT HAS RECEIVED FULL AND SUFFICIENT
CONSIDERATION FOR THIS PROVISION (AND EACH OTHER PROVISION OF EACH OTHER LOAN
DOCUMENT TO WHICH IT IS A PARTY) AND THAT THIS PROVISION IS A MATERIAL
INDUCEMENT FOR THE LENDER PARTIES ENTERING INTO THE CREDIT AGREEMENT AND EACH
SUCH OTHER LOAN DOCUMENT.

            SECTION 5.13.     Additional Subsidiary Guarantors.  Upon
execution and delivery by the Agent and any other Person (each such Person
being an "Additional Subsidiary Guarantor") of an instrument in the form of
Annex I attached hereto, such Additional Subsidiary Guarantor shall become a
Subsidiary Guarantor hereunder with the same force and effect as if originally
named as a Subsidiary Guarantor herein.  The execution and delivery of any
such instrument shall not require the consent of any Subsidiary Guarantor
hereunder.  The rights and obligations of each Subsidiary Guarantor hereunder
shall remain in full force and effect notwithstanding the addition of any
Additional Subsidiary Guarantor as a party to this Guaranty.

               [REMAINDER OF THIS PAGE LEFT INTENTIONALLY BLANK]

            IN WITNESS WHEREOF, each Subsidiary Guarantor has caused this
Guaranty to be duly executed and delivered by its officer thereunto duly
authorized as of the date first above written.

                   SUBSIDIARY GUARANTOR GUARANTY SUPPLEMENT


            THIS SUBSIDIARY GUARANTOR GUARANTY SUPPLEMENT (this "Supplement"),
dated as of _____________, 199_, to the Subsidiary Guarantor Guaranty, dated
as of January 9, 1997 (as amended or otherwise modified through the date
hereof, the "Subsidiary Guaranty"), made by each Person identified on the
signature pages thereto, certain other Persons who subsequently became a party
thereto by executing an agreement in substantially the form hereof (each an
"Additional Subsidiary Guarantor" and, together with each Person identified on
the signature pages of the Guaranty, the "Subsidiary Guarantors"), in favor of
The Bank of Nova Scotia ("Scotiabank"), as documentation agent (the
"Documentation Agent") for each of the Lender Parties (such capitalized term
and all other capitalized terms used in this Supplement without being defined
shall have the meaning provided for in the Subsidiary Guaranty).


                             W I T N E S S E T H:

            WHEREAS, pursuant to a Credit Agreement, dated as of January 9,
1997 (together with all amendments and other modifications, if any, from time
to time made thereto, the "Credit Agreement"), among ADT Operations, Inc., a
Delaware corporation (the "Borrower"), the financial institutions as are or
may become parties thereto (collectively, the "Lenders"), and The Bank of Nova
Scotia ("Scotiabank"), individually and as agent (the "Agent") for the
Lenders, the Lenders have extended Commitments to make Credit Extensions to or
on behalf of the Borrower;

            WHEREAS, it is in the best interests of the undersigned (the "New
Additional Subsidiary Guarantor") to execute this Supplement inasmuch as the
New Additional Subsidiary Guarantor will derive substantial direct and indirect
benefits from the Credit Extensions made by the Lenders pursuant to the Credit
Agreement; and

            WHEREAS, the New Additional Subsidiary Guarantor desires to become
an Additional Subsidiary Guarantor under the Subsidiary Guaranty pursuant to
Section 5.13 thereof;

            NOW, THEREFORE, for good and valuable consideration the receipt
of which is hereby acknowledged, the New Additional Subsidiary Guarantor
agrees, for the benefit of each Lender Party, as follows:

            SECTION 1.  Additional Subsidiary Guarantor.  In accordance with
Section 5.13 of the Subsidiary Guaranty, the New Additional Subsidiary
Guarantor by its signature hereto shall become a Subsidiary Guarantor under
the Subsidiary Guaranty with the same force and effect as if originally named
as a Subsidiary Guarantor therein, and each reference to a "Subsidiary
Guarantor" or an "Additional Subsidiary Guarantor" in the Subsidiary Guaranty
shall be deemed to include the New Additional Subsidiary Guarantor.  The New
Additional Subsidiary Guarantor hereby agrees to all the terms and provisions
of the Subsidiary Guaranty applicable to it as an Additional Subsidiary
Guarantor thereunder.

            SECTION 2.  Guaranty.  Without limiting the terms of Section 1, the
New Additional Subsidiary Guarantor hereby absolutely, unconditionally and
irrevocably, jointly and severally,

                  (a)  guarantees the full and punctual payment when due,
            whether at stated maturity, by required prepayment, declaration,
            acceleration, demand or otherwise, of all Obligations of the
            Borrower and each other Obligor, whether for principal, interest,
            fees, expenses or otherwise (including all such amounts which
            would become due but for the operation of the automatic stay under
            Section 362(a) of the United States Bankruptcy Code, 11 U.S.C.
            Section 362(a), and the operation of Sections 502(b) and 506(b) of
            the United States Bankruptcy Code, 11 U.S.C. Section 502(b) and
            Section 506(b)); and

                  (b)  indemnifies and holds harmless each Lender Party and
            each holder of a Note for any and all costs and expenses (including
            reasonable attorney's fees and expenses) incurred by such Lender
            Party or such holder, as the case may be, in enforcing any rights
            under this Supplement or the Subsidiary Guaranty;

provided, however, that the New Additional Subsidiary Guarantor shall be
liable under this Supplement and the Subsidiary Guaranty for the maximum
amount of such liability that can be incurred without rendering this Supplement
and the Subsidiary Guaranty, as it relates to the New Additional Subsidiary
Guarantor, voidable under applicable law relating to fraudulent conveyance or
fraudulent transfer, and not for any greater amount.  This Supplement and the
Subsidiary Guaranty constitute a guaranty of payment when due and not of
collection, and the New Additional Subsidiary Guarantor specifically agrees
that it shall not be necessary or required that any Lender Party or any holder
of any Note exercise any right, assert any claim or demand or enforce any
remedy whatsoever against the Borrower or any other Obligor (or any other

therefor, direct that the Term Advance shall, at the beginning of any Interest
Period relating thereto, be divided into (and thereafter, save as otherwise
provided herein, treated in all respects as) two or more Term Advances having
such Original Amounts (in aggregate equalling the Original Amount of the Term
Advance) as shall be specified by the Borrower in such notice  Provided that
the Borrower shall not be entitled to make such a direction if:

      (a)   as a result of so doing there would be more than four outstanding
            Term Advances; or

      (b)   any Term Advance thereby coming into existence would have an
            Original Amount of less than  Pound Sterling5,000,000.

7.    Payment and Calculation of Interest

7.1   Payment of Interest  On the last day of each Interest Period (and, in
the case of any Interest Period in excess of six months, on the last day of
the first six months of such Interest Period) the Borrower shall pay accrued
interest on the Term Advance to which such Interest Period relates.

7.2   Calculation of Interest  The rate of interest applicable to a Term
Advance from time to time during an Interest Period relating thereto shall be
the rate per annum which is the sum of the Margin, the Associated Costs Rate
(save in the case of a Double Tax Treaty Bank which does not incur the costs
of complying with the reserve asset requirements of the Bank of England) in
respect of such Interest Period and LIBOR on the Quotation Date therefor.

8.    Alternative Interest Rates/Market Disruption

      If in respect of any Term Advance:

      (a)   LIBOR is to be calculated in accordance with paragraph (b) of
            Clause 1.6 (Screen Rates) and the Agent determines that at or
            about 11.00 a.m. (London time) on the Quotation Date for an
            Interest Period in respect of the Term Advance none of the
            Reference Banks was offering to prime banks in the London
            Interbank Market deposits in sterling for the proposed duration of
            such Interest Period; or

      (b)   before 11.30 a.m. (London time) on the Quotation Date for an
            Interest Period in respect of the Term Advance, the Agent has been
            notified by a Term Bank or each of a group of Term Banks to whom
            in aggregate fifty per cent. or more of the Term Advance is (or,
            in the case of the Term Advance being undrawn, if the Term Advance
            were then made, would be) owed that the rate at which such
            deposits were being so offered does not accurately reflect the
            cost to it of obtaining such deposits,

then, notwithstanding the provisions of Clause 6 (Interest Periods) and Clause
7 (Payment and Calculation of Interest):

              (i)       if paragraph (a) above applies, the duration of that
                        Interest Period shall be one month or, if less, such
                        that it shall end on the Final Maturity Date; and

             (ii)       if either paragraph (a) or (b) above applies, the rate
                        of interest applicable to the Term Advance from time
                        to time during such Interest Period shall be the rate
                        per annum which is the sum of the Margin, the
                        Associated Costs Rate (save in the case of a Double Tax
                        Treaty Bank which does not incur the costs of
                        complying with the reserve asset requirements of the
                        Bank of England) in respect of such Interest Period
                        and the rate per annum determined by the Agent to be
                        the arithmetic mean (rounded if necessary upwards to
                        five decimal places) of the rates notified by each
                        Term Bank to the Agent before the last day of such
                        Interest Period to be those which express as a
                        percentage rate per annum the cost to each Term Bank
                        of funding from whatever sources it may reasonably
                        select its portion of the Term Advance during such
                        Interest Period.

9.    Alternative Interest Rates/Substitute Basis or Repayment  If either of
those events mentioned in paragraphs (a) and (b) of Clause 8 (Alternative
Interest Rates/Market Disruption) occurs in relation to a Term Advance, then:

      (a)    the Agent shall notify the Borrower and the Term Banks of such
             event;

      (b)    thereupon the Agent, the Borrower and the Term Banks shall enter
             into negotiations with a view to agreeing a substitute basis (1)
             for determining the rates of interest from time to time
             applicable to the Term Advance and/or (2) upon which the Term
             Advance may be maintained (whether in sterling or some other
             currency) thereafter and any such substitute basis that is agreed
             shall take effect in accordance with its terms and be binding on
             the Obligors and the Term Bank agreeing thereto;

      (c)    if a substitute basis has not been agreed within 30 days of such
             notification, each Term Bank has the right to stipulate in its
             absolute discretion the rate of interest applicable to its
             portion of the Term Advance, and that rate shall be binding on the
             Borrower, provided that the Borrower has the right to prepay the
             Term Advance in whole or in part, which right shall be exercised
             in such a way that the order in which the Term Banks are prepaid
             in respect of their portions of the Term Advance, shall be the
             same as the order of onerousness of the interest rates stipulated
             by each of the Term Banks, and such prepayments shall become due
             and payable on the last day of the Term Advance's then current
             Interest Period or the period by reference to which interest is
             determined; and

      (d)    while Clause 8 or this Clause 9 is in operation, their operation
             shall be subject to a weekly review by the Agent and the
             Borrower, with a view to reverting to normal interest provisions.


                                    PART 4
                    REPAYMENT, CANCELLATION AND PREPAYMENT

10.   Repayment

      Repayment of Term Loan  The Borrower shall repay the Term Loan in full
on the Final Maturity Date.

11.   Cancellation and Prepayment

11.1  Mandatory Cancellation of Term Facility  If the Agent has not on the
Closing Date received a Notice of Drawdown in respect of the Term Facility
complying in all respects with Clause 4.1 (Drawdown Conditions  - Term
Facility) (or the Term Facility is not for any reason whatsoever drawn in
accordance with the provisions hereof in the full amount on the Closing Date)
the whole of the Term Facility or, if part only of the Term Facility is drawn,
the portion of the Term Facility that remains undrawn as at the Closing Date
and the Term Commitment of each Term Bank shall be reduced to zero on the
Closing Date.

11.2  Optional Cancellation of Overdraft Facility  The Borrower may, at any
time by giving to the Overdraft Bank (with a copy to the Agent) not less than
ten business days' prior notice to that effect, cancel the whole or any part
of the Overdraft Facility.

11.3  Optional Prepayment of Term Advance  The Borrower may, if it has given
to the Agent not less than ten business days' prior notice to that effect,
prepay the whole of the Term Advance or any part of the Term Advance (in a
minimum amount of  Pound Sterling5,000,000 or the balance of the Term Loan
outstanding, if less) plus accrued interest (and other amounts that may be due
under the Finance Documents) on any business day; any prepayment so made shall
satisfy pro tanto the Borrower's obligations under Clause 10 (Repayment).

11.4  Notice of Cancellation or Prepayment  Any notice of cancellation or
prepayment given by the Borrower pursuant to Clause 11.2 (Optional
Cancellation of Overdraft Facility) or Clause 11.3 (Optional  Prepayment of
Term Advance) shall be irrevocable, shall specify the date upon which such
cancellation or prepayment is to be made and the amount of such cancellation
or prepayment and, in the case of a notice of prepayment, shall oblige the
Borrower to make such prepayment on such date.

11.5  Repayment of a Term Bank's Share of the Term Loan  If any Term Bank
claims indemnification from the Borrower under Clause 12.1 (Tax Gross-up) or
Clause 12.2 (Tax Indemnity) or Clause 14.1 (Increased Costs) and within thirty
days thereafter the Agent receives from the Borrower at least ten business
days' prior notice (which shall be irrevocable) of the Borrower's intention to
repay such Term Bank's share of the Term Loan, the Borrower shall on the last
day of each of the then current Interest Periods repay such Term Bank's
portion of the Term Advance; any repayment so made shall reduce rateably the
remaining obligations of the Borrower under Clause 10 (Repayment).

11.6  No Other Repayments and no Reborrowing  The Borrower shall not repay all
or any part of the Term Loan except at the times and in the manner expressly
provided for in this Agreement and shall not be entitled to reborrow any such
amount repaid.


                                    PART 5
                                RISK ALLOCATION

12.   Taxes

12.1  Tax Gross-up  All payments to be made by any of the Obligors to any Bank
or the Agent hereunder shall be made free and clear of and without deduction
for or on account of tax unless such Obligor is required to make such a
payment subject to the deduction or withholding of tax (not being a tax
imposed on and calculated by reference to the net income paid to and received
by such Bank or the Agent by the jurisdiction in which it is incorporated or
in which its Facility Office (if any) is located), in which case the sum
payable by such Obligor in respect of which such deduction or withholding is
required to be made shall be increased to the extent necessary to ensure that,
after the making of the required deduction or withholding, such Bank or the
Agent receives and retains (free from any liability in respect of any such
deduction or withholding) a net sum equal to the sum which it would have
received and so retained had no such deduction or withholding been made or
required to be made.

12.2  Tax Indemnity  Without prejudice to the provisions of Clause 12.1 (Tax
Gross-up), if any Bank (or the Agent on its behalf) or the Agent is required
to make any payment on account of tax (not being a tax imposed on and
calculated by reference to the net income paid to and received by its Facility
Office by the jurisdiction in which it is incorporated or in which its
Facility Office is located) or otherwise on or in relation to any sum received
or receivable hereunder by such Bank (or the Agent on its behalf) or the Agent
(including any sum received or receivable under this Clause 12) or any
liability in respect of any such payment is asserted, imposed, levied or
assessed against such Bank (or the Agent on its behalf) or the Agent, the
Borrower shall, upon demand of the Agent, promptly indemnify such Bank or the
Agent against such payment or liability, together with any interest,
penalties, costs and expenses payable or incurred in connection therewith but
only to the extent necessary to put such Bank or the Agent in the same
economic position that it would have been in had no such tax been imposed.

12.3  Claims by Banks  A Bank intending to make a claim pursuant to Clause
12.2 (Tax Indemnity) shall notify the Agent of the event by reason of which it
is entitled to do so, whereupon the Agent shall notify the Borrower thereof
Provided that (i) nothing herein shall require such Bank to disclose any
confidential information relating to the organisation of its affairs and (ii)
if a Bank notifies the Agent of a claim under Clause 12.2 after the date
falling 60 days after the date on which such Bank receives its audited annual
accounts such Bank shall not be entitled to claim indemnification for any
event or occurrence which occurred during the financial year to which such
audited annual accounts relate.

12.4  Double Tax Treaty Banks

      (i)    The Borrower shall take promptly such action (including, without
             limitation, the provision of certificates and/or the making of
             claims to any relevant taxation or other authority) as the Agent
             or any Double Tax Treaty Bank may reasonably require for the
             purpose of compliance with the requirements of the relevant double
             tax treaty.

      (ii)   Subject to the Borrower being in compliance with Clause 12.4(i),
             no Obligor shall be liable, otherwise than by reason or result of
             a change of law or treaty or any change in its interpretation or
             administration, to make the additional payments to the Double Tax
             Treaty Bank as contemplated by this Clause 12.

13.   Tax Receipts

13.1  Notification of Requirement to Deduct Tax  If, at any time, either of
the Obligors is required by law to make any deduction or withholding from any
sum payable by it hereunder (or if thereafter there is any change in the rates
at which or the manner in which such deductions or withholdings are
calculated), such Obligor shall promptly notify the Agent.

13.2  Evidence of Payment of Tax  If any of the Obligors makes any payment
hereunder in respect of which it is required to make any deduction or
withholding, it shall pay the full amount required to be deducted or withheld
to the relevant taxation or other authority within the time allowed for such
payment under applicable law and shall deliver to the Agent for each Bank,
within thirty days after it has made such payment to the applicable authority
(or, if later, within 10 business days of receipt), an original receipt (or a
certified copy thereof) issued by such authority evidencing the payment to
such authority of all amounts so required to be deducted or withheld in
respect of that Bank's share of such payment.

13.3  If any Bank:

      (a)    (if it has a Facility Office in the United Kingdom) is not or
             ceases to be a bank as defined in the Income and Corporation
             Taxes Act 1988 for the purposes of Section 349 of that Act which
             is within the charge to UK corporation tax as regards any
             interest received by it under this Agreement (a "Section 349
             Bank") or

      (b)    (if it does not have a Facility Office in the United Kingdom) is
             not or ceases to be a Double Tax Treaty Bank

then it shall promptly notify the Agent upon becoming aware of the same who
shall promptly notify the Borrower and the Borrower shall not be liable to pay
to such Bank under Clauses 12 or 13 any amount in excess of the amount it
would have been obliged to pay if such Bank (i) was or had not ceased to be a
Section 349 Bank or, as the case may be, (ii) was or had not ceased to be a
Double Tax Treaty Bank  Provided that this Clause 13.3 shall not apply (and
the Borrower shall be obliged to comply with its obligations under Clauses 12
and 13) if after the date hereof there shall have been any change in, or in
the interpretation or application of, any relevant law, directive, treaty
(including, without limitation, any applicable double tax treaty) or
regulation or the practice of the United Kingdom Inland Revenue and as a
result thereof the relevant Bank ceases to be a Section 349 Bank or Double Tax
Treaty Bank or the Borrower would be required to make a deduction or
withholding on account of tax irrespective of whether the recipient of the
relevant payment is or is not a Section 349 Bank or Double Tax Treaty Bank.

13.4  If any Bank receives the benefit or any tax credit, refund or allowance
resulting from a payment which includes an additional amount paid by the
Borrower under Clauses 12 or 13, it shall, to the extent that it can do so
without prejudice to the retention of the relevant benefit, pay to the
Borrower such part of that benefit as will leave that Bank (after such
payment) in no more or less favourable a position than it would have been in
if no additional amount had been required to be paid provided that:

      (a)    the Bank shall be the sole judge of the amount of any such
             benefit and of the date on which it is received;

      (b)    the Bank shall have a discretion as to the order and manner in
             which it employs or claims tax credits, refunds and allowances
             available to it and, in particular, shall be entitled to arrange
             its tax affairs in whatever manner it thinks fit; and

      (c)    the Bank shall not be obliged to disclose to the Borrower any
             information regarding its tax affairs or tax computations.

14.   Changes in Circumstances

14.1  Increased Costs  If, by reason of (i) any change in law or in its
interpretation or administration and/or (ii) compliance with any Capital
Adequacy Requirement or any other request from or requirement of any central
bank (other than the requirements of the Bank of England reflected in the
Associated Costs Rate and other than as covered by Clause 12) or other fiscal,
monetary or other authority:

      (a)    a Bank or any holding company of such Bank is unable to obtain
             the rate of return on its capital which it would have been able
             to obtain but for such Bank's entering into or assuming or
             maintaining a commitment or performing its obligations (including
             its obligation to participate in the making of Term Advances or
             maintain the Overdraft Facility) under this Agreement;

      (b)    a Bank or any holding company of such Bank incurs a cost as a
             result of such Bank's entering into or assuming or maintaining a
             commitment or performing its obligations (including its
             obligation to participate in the making of Term Advances or
             maintain the Overdraft Facility) under this Agreement;

      (c)    there is any increase in the cost to a Bank or any holding
             company of such Bank of funding or maintaining all or any of the
             loans comprised in a class of loans formed by or including such
             Bank's share of the Term Advances or funding and maintaining the
             Overdraft Facility; or

      (d)    a Bank or any holding company of such Bank becomes liable to make
             any payment on account of tax or otherwise (not being a tax
             imposed on and calculated by reference to the net income paid to
             and received by such Bank's Facility Office by the jurisdiction
             in which it is incorporated or in which its Facility Office is
             located) on or calculated by reference to the amount of such
             Bank's share of the Term Advances, its funding the Overdraft
             Facility and/or to any sum received or receivable by it
             hereunder,

then the Borrower shall, from time to time on demand of the Agent, within
fourteen days of such demand pay to the Agent for the account of that Bank
amounts sufficient to hold harmless and indemnify that Bank or such Bank's
holding company from and against, as the case may be, (1) such reduction in
the rate of return on capital, (2) such cost, (3) such increased cost (or such
proportion of such increased cost as is, in the opinion of that Bank,
attributable to its participating in the funding or maintaining of Term
Advances or, as the case may be, the Overdraft Facility), or (4) such
liability.

14.2  Exceptions  Clause 14.1 shall not apply to any cost, reduction,
      increased cost or liability:

      (a)    attributable to any breach by the relevant Bank (or its holding
             company) of any applicable law or any request or requirement of
             any central bank or other fiscal, monetary or other authority; or

      (b)    relating to tax on a Bank's (or its holding company's) overall
             net income.

14.3  Increased Costs Claims  A Bank intending to make a claim pursuant to
Clause 14.1 (Increased Costs) shall notify the Agent of the event by reason of
which it is entitled to do so, whereupon the Agent shall notify the Borrower
thereof  Provided that (i) nothing herein shall require such Bank to disclose
any confidential information relating to the organisation of its affairs and
(ii) if a Bank notifies the Agent of a claim under Clause 14.1 after the date
falling 60 days after the date on which such Bank receives its audited annual
accounts such Bank shall not be entitled to claim indemnification in respect
of the financial year to which such audited annual accounts relate.

14.4  Illegality  If, at any time, it is unlawful for a Bank to make, fund or
allow to remain outstanding all or part of its share of the Term Advances or
to make or fund the Overdraft Facility, then that Bank shall, promptly after
becoming aware of the same, deliver to the Borrower through the Agent a notice
to that effect and:

      (a)    such Bank shall not thereafter be obliged to participate in the
             making of any Term Advances and the amount of its Available Term
             Commitment or in the case of the Overdraft Bank its Overdraft
             Commitment, shall be immediately reduced to zero; and

      (b)    if the Agent on behalf of such Bank so requires, the Borrower
             shall on such date as the Agent shall have specified (or, if
             later, any date which the Borrower shall notify and which falls
             prior to the date upon which such illegality is to occur) repay
             such Bank's share of any outstanding Term Advances or in the case
             of the Overdraft Bank any amounts outstanding under the Overdraft
             Facility together with accrued interest thereon and all other
             amounts owing to such Bank hereunder and, in the case of Term
             Advances, any repayment so made shall reduce rateably the
             remaining obligations of the Borrower under Clause 10
             (Repayment).

14.5  Mitigation  If circumstances are such that a Bank intends to claim
indemnification from the Borrower under Clause 12.2 (Tax Indemnity) or Clause
14.1 (Increased Costs) or if Clause 12.1 or 14.4 applies to a Bank such Bank
shall, after consultation with the Agent and the Borrower and to the extent
that it can do so lawfully and without prejudice to its own position, take
such steps as it considers reasonable (including a change in its Facility
Office or the transfer of its rights, benefits and obligations hereunder to
another financial institution acceptable to the Borrower and willing to
participate in the Facility) with a view to mitigating the effect of such
circumstances on the Borrower.

projections contained in the Information Memorandum were made or prepared in
good faith based on reasonable assumptions but, as regards any forecasts
contained in the Information Memorandum, no representation or warranty is

adverse effect on the business, results of operations, financial condition or

or becoming void, voidable, unenforceable or ineffective as against the
Borrower for any reason whatsoever, whether or not known to the Agent, the
Arranger and the Banks or any of them or any other person, the amount of such
loss being the amount which the person or persons suffering it would otherwise
have been entitled to recover from the Borrower.

20.3  Additional Security  The obligations of the Group Guarantors herein
contained shall be in addition to and independent of every other security
which the Agent, the Arranger and the Banks or any of them may at any time
hold in respect of any of the Borrower's obligations under the Finance
Documents.

20.4  Continuing Obligations  The obligations of the Group Guarantors herein
contained shall constitute and be continuing obligations notwithstanding any
settlement of account or other matter or thing whatsoever and shall not be

continue in full force and effect until final payment in full of all amounts
owing by the Borrower under the Finance Documents and total satisfaction of
all the Borrower's actual and contingent obligations under the Finance

            Documents;

      (d)   any amendment to, or any variation, waiver or release of, any
            obligation of any Obligor under any of the Finance Documents or

            obligations under any of the Finance Documents;

      (f)   any failure to realise or fully to realise the value of, or any

            Finance Documents; or

      (g)   any other act, event or omission which, but for this Clause 20.5,
            might operate to discharge, impair or otherwise affect any of the
            obligations of any  Group Guarantor herein contained or any of the
            rights, powers or remedies conferred upon the Agent, the Arranger
            and the Banks or any of them by any of the Finance Documents or by
            law.

20.6  Settlement Conditional  Any settlement or discharge between any of the
Group Guarantors and the Agent, the Arranger and the Banks or any of them
shall be conditional upon no security or payment to the Agent, the Arranger
and the Banks or any of them by the Borrower or any Guarantor or any other
person on behalf of the Borrower or, as the case may be, any Guarantor being
avoided or reduced by virtue of any provisions or enactments relating to
bankruptcy, insolvency, liquidation or similar laws of general application for
the time being in force and, if any such security or payment is so avoided or
reduced, the Agent, the Arranger and the Banks shall each be entitled to
recover the value or amount of such security or payment from the Group
Guarantors subsequently as if such settlement or discharge had not occurred.

20.7  Exercise of Rights  Neither the Agent, the Arranger and the Banks nor
any of them shall be obliged before exercising any of the rights, powers or

      (a)   to make any demand of the Borrower or any other Obligor;

      (b)   to take any action or obtain judgment in any court against the

      (c)   to make or file any claim or proof in a winding-up or dissolution
            of the Borrower or any other Obligor; or

      (d)   to enforce or seek to enforce any other security taken in respect
            of any of the obligations of the Borrower or any other Obligor
            under any of the Finance Documents;

save that notice of non-payment shall first be given to the Borrower provided
that if no such notice is given to the Borrower prior to the exercise of such
rights, powers or remedies, that does not preclude the Agent, the Arranger and
the Banks or any of them, giving notice to the Borrower and thereafter
exercising such rights, powers or remedies.

20.8  Deferral of Group Guarantor's Rights  The Group Guarantors agree that,
so long as any amounts are or may be owed by the Borrower under any of the
Finance Documents or the Borrower is under any actual or contingent
obligations under any of the Finance Documents, the Group Guarantors shall not
exercise any rights which the Group Guarantors may at any time have by reason
of performance by it of its obligations hereunder:

      (a)   to be indemnified by the Borrower; and/or

      (b)   to claim any contribution from any other guarantor of the
            Borrower's obligations under any of the Finance Documents; and/or

      (c)   to take the benefit (in whole or in part and whether by way of
            subrogation or otherwise) of any rights of the Agent, the Arranger
            and the Banks under any of the Finance Documents or of any other
            security taken pursuant to, or in connection with, any of the
            Finance Documents by all or any of the Agent, the Arranger and the
            Banks,

Provided that the restrictions contained in (a) and (b) above shall only apply
after the occurrence of an Event of Default but shall apply irrespective of
when the claim for contribution or indemnification under this Clause 20.8
arose.

20.9  Suspense Accounts  All moneys received, recovered or realised by a Bank
by virtue of Clause 20.1 (Guarantee) or Clause 20.2 (Indemnity) may, in that
Bank's discretion, be credited to a suspense or impersonal account and may be
held in such account for so long as such Bank thinks fit pending the
application from time to time (as such Bank may think fit) of such moneys
in or towards the payment and discharge of any amounts owing by any of the
Obligors to such Bank under any of the Finance Documents.  If and when the
aggregate of all moneys held on suspense or impersonal account exceeds the
aggregate amount payable by the Borrower under the Finance Documents to
such Bank, such Bank shall, as soon as practicable thereafter, apply any
amount held in such suspense or impersonal account in satisfaction of the
amounts payable by the Obligors under the Finance Documents.


                                    PART 8
                        DEFAULT INTEREST AND INDEMNITY

21.   Default Interest and Indemnity

21.1  Default Interest Periods  If any sum due and payable by any of the
Obligors under  any of the Finance Documents is not paid on the due date
therefor in accordance with the provisions of Clause 23 (Payments) or if any
sum due and payable by any of the Obligors under any judgment of any court in
connection herewith is not paid on the date of such judgment, the period
beginning on such due date or, as the case may be, the date of such judgment
and ending on the date upon which the obligation of such Obligor to pay such
sum (the balance thereof for the time being unpaid being herein referred to as
an "unpaid sum") is discharged shall be divided into successive periods, each
of which (other than the first) shall start on the last day of the preceding
such period and the duration of each of which shall (except as otherwise
provided in this Clause 21) be selected by the Agent.

21.2  Default Interest  During each such period relating thereto as is
mentioned in Clause 21.1 (Default Interest Periods) an unpaid sum shall bear
interest at the rate per annum which is the sum from time to time of two per
cent., the Margin, the Associated Costs Rate in respect thereof at such time
and LIBOR on the Quotation Date therefor  Provided that:

      (a)   if, for any such period, LIBOR cannot be determined, the rate of
            interest applicable to such unpaid sum shall be the rate per annum
            which is the sum of two per cent., the Margin, the Associated
            Costs Rate (save in the case of a Double Tax Treaty Bank which
            does not incur the costs of complying with the reserve asset
            requirements of the Bank of England) in respect thereof at such
            time and the rate per annum determined by the Agent to be equal to
            the arithmetic mean (rounded upwards, if not already such a
            multiple, to the nearest whole multiple of one-sixteenth of one
            per cent.) of the rates notified by each of the Reference Banks
            to the Agent before the last day of such period to be those
            which express as a percentage rate per annum the cost to it of
            funding from whatever sources it may select its portion of such
            unpaid sum for such period; and

      (b)   if such unpaid sum is all or part of a Term Advance which became
            due and payable on a day other than the last day of an Interest
            Period relating thereto, the first such period applicable thereto
            shall be of a duration equal to the unexpired portion of that
            Interest Period and the rate of interest applicable thereto from
            time to time during such period shall be that which exceeds by two
            per cent. the rate which would have been applicable to it had it
            not so fallen due.

21.3  Payment of Default Interest  Any interest which shall have accrued under
Clause 21.2 (Default Interest) in respect of an unpaid sum shall be due and
payable and shall be paid by the Obligor owing such unpaid sum at the end of
the period by reference to which it is calculated.

21.4  Broken Periods  If any Bank or the Agent on its behalf receives or
recovers all or any part of such Bank's share of a Term Advance otherwise than
on the last day of an Interest Period relating to that Term Advance, the
Borrower shall pay to the Agent within fourteen days of its receipt of written
notice from the Agent for account of such Bank an amount equal to the amount
(if any) by which (a) the additional interest which would have been payable on
the amount so received or recovered had it been received or recovered on the
last day of that Interest Period (less Margin and Associated Costs) exceeds
(b) the amount of interest which in the opinion of the Agent would have been
payable to the Agent on the last day of that Interest Period in respect of a
sterling deposit equal to the amount so received or recovered placed by it
with a prime bank in London for a period starting on the third business day
following the date of such receipt or recovery and ending on the last day of
that Interest Period.

21.5  Borrower's Indemnity  The Borrower undertakes to indemnify:

      (a)   each of the Agent, the Arranger and the Banks against any cost,
            claim, loss, expense (including legal fees) or liability together
            with any VAT thereon, which any of them may sustain or incur as a
            consequence of the occurrence of any Event of Default or any
            default by the Borrower in the performance of any of the
            obligations expressed to be assumed by it in any of the Finance
            Documents; and

      (b)   each Bank against any loss it may suffer or incur as a result of
            its funding or making arrangements to fund its portion of a Term
            Advance requested by the Borrower under any of the Finance
            Documents but not made by reason of the operation of any one or
            more of the provisions hereof (other than default by or gross
            negligence of such Bank or the Agent).

21.6  Unpaid Sums as Term Advances  Any unpaid sum shall (for the purposes of
this Clause 21, Clause 14.1 (Increased Costs)and the Fifth Schedule
(Associated Costs Rate)) be treated as an advance and accordingly in this
Clause 21, Clause 14.1 (Increased Costs) and the Fifth Schedule (Associated
Costs Rate)) the term "Term Advance" includes any unpaid sum and the term
"Interest Period", in relation to an unpaid sum, includes each such period
relating thereto as is mentioned in Clause 21.1 (Default Interest Periods).


                                    PART 9
                                   PAYMENTS

22.   Currency of Account and Payment

22.1  Currency of Account  Sterling is the currency of account and payment for
each and every sum at any time due from any of the Obligors under  any of the
Finance Documents  Provided that:

      (a)   each payment in respect of costs and expenses shall be made in the
            currency in which the same were incurred; and

      (b)   each payment pursuant to Clause 12.2 (Tax Indemnity) or Clause
            14.1 (Increased Costs) shall be made in the currency specified by
            the party claiming thereunder.

22.2  Currency Indemnity  If any sum due from any of the Obligors under this
Agreement or any order or judgment given or made in relation hereto has to be
converted from the currency (the "first currency") in which the same is
payable hereunder or under such order or judgment into another currency (the
"second currency") for the purpose of (a) making or filing a claim or proof
against such Obligor, (b) obtaining an order or judgment in any court or other
tribunal or (c) enforcing any order or judgment given or made in relation
hereto, the Borrower shall indemnify and hold harmless each of the persons to
whom such sum is due from and against any loss suffered or incurred as a
result of any discrepancy between (i) the rate of exchange used for such
purpose to convert the sum in question from the first currency into the second
currency and (ii) 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 it in satisfaction, in whole or in
part, of any such order, judgment, claim or proof.

23.   Payments

23.1  Payments to the Agent  On each date on which this Agreement requires an
amount denominated in sterling to be paid by any of the Obligors or any of the
Banks under any of the Finance Documents, such Obligor or, as the case may be,
such Bank shall make the same available to the Agent by payment in sterling
and in immediately available, freely transferable, cleared funds to The Bank
of Nova Scotia, London, Sort Code 30-16-61 (or such other account or bank as
the Agent may have specified for this purpose).

23.2  Alternative Payment Arrangements  If, at any time, it shall become
impracticable (by reason of any action of any governmental authority or any
change in law, exchange control regulations or any similar event) for any of
the Obligors to make any payments under any of the Finance Documents in the
manner specified in Clause 23.1 (Payments to the Agent), then such Obligor may
agree with each or any of the Banks alternative arrangements for the payment
direct to such Bank of amounts due to such Bank under any of the Finance
Documents  Provided that, in the absence of any such agreement with any Bank,
such Obligor shall be obliged to make all payments due to such Bank in the
manner specified herein.  Upon reaching such agreement such Obligor and such
Bank shall immediately notify the Agent thereof and shall thereafter promptly
notify the Agent of all payments made direct to such Bank.

23.3  Payments by the Agent  Save as otherwise provided herein, each payment
received by the Agent for the account of another person pursuant to Clause
23.1 (Payments to the Agent) shall be made available by the Agent to such
other person (in the case of a Bank, for the account of its Facility Office)
for value the same day by transfer to such account of such person with such
bank in London as such person shall have previously notified to the Agent.

23.4  No Set-off  All payments required to be made by any of the Obligors
under any of the Finance Documents shall be calculated without reference to
any set-off or counterclaim and shall be made free and clear of and without
any deduction for or on account of any set-off or counterclaim.

23.5  Clawback  Where a sum is to be paid under any of the Finance Documents
to the Agent for account of another person, the Agent shall not be obliged to
make the same available to that other person until it has been able to
establish to its satisfaction that it has actually received such sum, but if
it does so and it proves to be the case that it had not actually received such
sum, then the person to whom such sum was so made available shall on request
refund the same to the Agent together with an amount sufficient to indemnify
the Agent against any cost or loss it may have suffered or incurred by reason
of its having paid out such sum prior to its having received such sum.

23.6  Non Business Days  If a payment would otherwise fall due on a day which
is not a business day, it shall instead be due on the next succeeding business
day.

24.   Set-Off

24.1  Contractual Set-off  On or after the occurrence of an Event of Default
(if the same is still continuing), each of the Obligors authorises each Bank
to apply any credit balance to which such Obligor is entitled on any account
of such Obligor with that Bank in satisfaction of any sum due and payable from
such Obligor to such Bank under  any of the Finance Documents but unpaid; for
this purpose, each Bank is authorised to purchase with the moneys standing to
the credit of any such account such other currencies as may be necessary to
effect such application.

24.2  Set-off not Mandatory  No Bank shall be obliged to exercise any right
given to it by Clause 24.1 (Contractual Set-off).

25.   Sharing

25.1  Redistribution of Payments  If, at any time, the proportion which any
Bank (a "Recovering Bank") has received or recovered (whether by payment, the
exercise of a right of set-off or combination of accounts or otherwise) in
respect of its portion of any payment (a "relevant payment") to be made under
this Agreement by any of the Obligors for account of such Recovering Bank and
one or more other Banks is greater (the portion of such receipt or recovery
giving rise to such excess proportion being herein called an "excess amount")
than the proportion thereof so received or recovered by the Bank or Banks so
receiving or recovering the smallest proportion thereof, then:

      (a)   such Recovering Bank shall inform the Agent of such receipt or
            recovery and pay to the Agent an amount equal to such excess
            amount;

      (b)   there shall thereupon fall due from such Obligor to such
            Recovering Bank an amount equal to the amount paid out by such
            Recovering Bank pursuant to paragraph (a) above, the amount so due
            being, for the purposes hereof, treated as if it were an unpaid
            part of such Recovering Bank's portion of such relevant payment;
            and

      (c)   the Agent shall treat the amount received by it from such
            Recovering Bank pursuant to paragraph (a) above as if such amount
            had been received by it from such Obligor in respect of such
            relevant payment and shall pay the same to the persons entitled
            thereto (including such Recovering Bank) pro rata to their
            respective entitlements thereto.

25.2  Repayable Recoveries  If any sum (a "relevant sum") received or
recovered by a Recovering Bank in respect of any amount owing to it by any of
the Obligors becomes repayable and is repaid by such Recovering Bank, then:

      (a)   each Bank which has received a share of such relevant sum by
            reason of the implementation of Clause 25.1 (Redistribution of
            Payments) shall, upon request of the Agent, pay to the Agent for
            account of such Recovering Bank an amount equal to its share of
            such relevant sum; and

            an amount equal to the amount paid out by it pursuant to paragraph
            (a) above, the amount so due being, for the purposes hereof,
            treated as if it were the sum payable to such Bank against which
            such Bank's share of such relevant sum was applied.

Agent to act as its agent in connection with the Finance Documents and

discretions as are specifically delegated to the Agent by the terms of  the
Finance Documents together with all such rights, powers, authorities and
discretions as are reasonably incidental thereto.

28.2  Agent's Discretions  The Agent may:

      (a)   assume, unless it has, in its capacity as agent for the Banks,
            received notice to the contrary from any other party to any of the
            Finance Documents, that (i) any representation made by any of the

            (ii) no Event of Default or Potential Event of Default has
            occurred, (iii) none of the Obligors is in breach of or default
            under its obligations under any of the Finance Documents and (iv)
            any right, power, authority or discretion vested herein upon an

            persons has not been exercised;

      (b)   assume that the Facility Office of each Bank is that identified
            with its signature below (or, in the case of a Transferee, at the
            end of the Transfer Certificate to which it is a party as
            Transferee) until it has received from such Bank a notice
            designating some other office of such Bank to replace its Facility
            Office and act upon any such notice until the same is superseded
            by a further such notice;

      (c)   engage and pay for the advice or services of any lawyers,
            accountants, surveyors or other experts whose advice or services
            may to it seem necessary, expedient or desirable and rely upon any
            advice so obtained;

      (d)   rely as to any matters of fact which might reasonably be expected
            to be within the knowledge of any of the Obligors upon a
            certificate signed by or on behalf of such Obligor;

      (e)   rely upon any communication or document believed by it to be
            genuine;

      (f)   refrain from exercising any right, power or discretion vested in
            it as agent hereunder unless and until instructed by an
            Instructing Group as to whether or not such right, power or
            discretion is to be exercised and, if it is to be exercised, as to
            the manner in which it should be exercised; and

      (g)   refrain from acting in accordance with any instructions of an
            Instructing Group to begin any legal action or proceeding arising
            out of or in connection with this Agreement until it shall have
            received such security as it may require (whether by way of
            payment in advance or otherwise) for all costs, claims, losses,
            expenses (including legal fees) and liabilities together with any
            VAT thereon which it will or may expend or incur in complying with
            such instructions.

28.3  Agent's Obligations  The Agent shall:

      (a)   promptly inform each Bank of the contents of any notice or
            document received by it in its capacity as Agent from any of the

            performance of or compliance with its obligations under any of the
            Finance Documents of which the Agent has notice from any other
            party hereto or the Group Parent;

      (c)   save as otherwise provided herein, act as agent under any of the
            Finance Documents in accordance with any instructions given to it
            by an Instructing Group, which instructions shall be binding on
            the Arranger and the Banks; and

      (d)   if so instructed by an Instructing Group, refrain from exercising
            any right, power or discretion vested in it as agent under any of
            the Finance Documents.

28.4  Excluded Obligations  Notwithstanding anything to the contrary expressed
or implied herein, neither the Agent nor the Arranger shall:

      (a)   be bound to enquire as to (i) whether or not any representation
            made by any of the Obligors in connection with any of the Finance
            Documents is true, (ii) the occurrence or otherwise of any Event
            of Default or Potential Event of Default, (iii) the performance by
            any of the Obligors of its obligations under any of the Finance

            of or under its obligations under any of the Finance Documents;

      (b)   be bound to account to any Bank for any sum or the profit element
            of any sum received by it for its own account;

      (c)   be bound to disclose to any other person any information relating
            to any member of the Group if such disclosure would or might in
            its opinion constitute a breach of any law or regulation or be
            otherwise actionable at the suit of any person; or

      (d)   be under any obligations other than those for which express
            provision is made herein.

28.5  Indemnification  Each Bank shall, from time to time on demand by the
Agent, indemnify the Agent, in the proportion its share of the Loan (or, if no
Term Advances have been made, its Available Term Commitment or in the case of
the Overdraft Bank, its Overdraft Commitment) bears to the amount of the Loan
(or, if no Term Advances have been made, the aggregate of the Available Term
Facility and the Overdraft Facility) at the time of such demand (or, if the
Loan has then been repaid in full, immediately prior to the final repayment
thereof), against any and all costs, claims, losses, expenses (including legal
fees) and liabilities together with any VAT thereon which the Agent may incur,
otherwise than by reason of its own gross negligence or wilful misconduct, in
acting in its capacity as agent under the Finance Documents.

28.6  Exclusion of Liabilities  Neither the Agent and the Arranger nor any of
them accepts any responsibility for the accuracy and/or completeness of any
information supplied by any of the Obligors in connection herewith or for the
legality, validity, effectiveness, adequacy or enforceability of any of the
Finance Documents and neither the Agent and the Arranger nor any of them shall
be under any liability as a result of taking or omitting to take any action in
relation to any of the Finance Documents, save in the case of gross negligence
or wilful misconduct.

28.7  No Actions  Each of the Banks agrees that it will not assert or seek to
assert against any director, officer or employee of the Agent or the Arranger
any claim it might have against any of them in respect of the matters referred
to in Clause 28.6 (Exclusion of Liabilities).

28.8  Business with the Group  The Agent and the Arranger may accept deposits
from, lend money to and generally engage in any kind of banking or other
business with any member of the Group.

28.9  Resignation  The Agent may resign its appointment hereunder at any time
without assigning any reason therefor by giving not less than thirty days'
prior written notice to that effect to each of the other parties hereto
Provided that no such resignation shall be effective until a successor for the
Agent is appointed in accordance with the succeeding provisions of this Clause
28.

28.10 Successor Agent  If the Agent gives notice of its resignation pursuant
to Clause 28.9 (Resignation), then any reputable and experienced bank or other
financial institution may, after consultation with the Borrower, be appointed
as a successor to the Agent by an Instructing Group during the period of such
notice but, if no such successor is so appointed, the Agent may appoint such
a successor itself.

28.11 Rights and Obligations  If a successor to the Agent is appointed under
the provisions of Clause 28.10 (Successor Agent), then (a) the retiring Agent
shall be discharged from any further obligation hereunder but shall remain
entitled to the benefit of the provisions of this Clause 28 and (b) its
successor and each of the other parties hereto shall have the same rights and
obligations amongst themselves as they would have had if such successor had
been a party hereto.

28.12 Own Responsibility  It is understood and agreed by each Bank that it has
itself been, and will continue to be, solely responsible for making its own
independent appraisal of and investigations into the financial condition,
creditworthiness, condition, affairs, status and nature of each member of the
Group and each member of the ADT Group and, accordingly, each Bank warrants to
the Agent and the Arranger that it has not relied on and will not hereafter
rely on the Agent and the Arranger or any of them:

      (a)   to check or enquire on its behalf into the adequacy, accuracy or
            completeness of any information provided by any of the Obligors in
            connection with this Agreement or the transactions herein
            contemplated (whether or not such information has been or is
            hereafter circulated to such Bank by the Agent and the Arranger or
            any of them); or

      (b)   to assess or keep under review on its behalf the financial
            condition, creditworthiness, condition, affairs, status or nature
            of any member of the Group or any member of the ADT Group.

28.13 Agency Division Separate  In acting as agent under the Finance Documents
for the Banks, the Agent shall be regarded as acting through its agency
division which shall be treated as a separate entity from any other of its
divisions or departments and, notwithstanding the foregoing provisions of this
Clause 28, any information received by some other division or department of
the Agent may be treated as confidential and shall not be regarded as having
been given to the Agent's agency division.

28.14 Confidential Information  Notwithstanding anything to the contrary
expressed or implied herein and without prejudice to the provisions of Clause
28.13 (Agency Division Separate), the Agent shall not as between itself and
the Banks be bound to disclose to any Bank or other person any information
which is supplied by any member of the Group or any member of the ADT Group to
the Agent in its capacity as agent hereunder for the Banks and which is
identified by such member of the Group or, as the case may be, of the ADT
Group at the time it is so supplied as being confidential information
Provided that the Agent shall disclose any information which in the reasonable
opinion of the Agent indicates that an Event of Default or Potential Event of
Default has occurred and may disclose to a Bank any information in respect of
which that Bank has given a confidentiality undertaking in a form satisfactory
to the Agent and the relevant member of the Group or, as the case may be, of
the ADT Group.

29.1  Binding Agreement  This Agreement shall be binding upon and enure to the
benefit of each party hereto and its or any subsequent successors, Transferees
and assigns.

29.2  No Assignments and Transfers by the Obligors  None of the Obligors shall
be entitled to assign or transfer all or any of its rights, benefits and
obligations under any of the Finance Documents.

29.3  Assignments and Transfers by Banks  Any Bank may, at any time, with the
prior written consent of the Borrower (such consent not to be unreasonably
withheld or delayed) assign all or, save in the case of the Overdraft Bank,
any of its rights and benefits under any of the Finance Documents or transfer
in accordance with Clause 29.5 (Transfers by Banks) all or, save in the case
of the Overdraft Bank, any of its rights, benefits and obligations under any
of the Finance Documents to any Section 349 Bank, in each case (as that term
is defined in Clause 13.3) or Double Tax Treaty Bank but not to any other
person  Provided that no such consent of the Borrower as is referred to in this
Clause 29.3 shall be required:

(i)   for an assignment or transfer by a Bank to an Affiliate of the Bank
      Provided that no Obligor shall be liable to pay any amounts under Part 5
      to any such Affiliate in excess of any amount which would have been
      payable in the absence of the assignment or transfer to such Affiliate
      if such liability:

      (a)   arises at the time of the assignment or transfer or as a result
            only of circumstances existing at such time or would arise as a
            result of any then current final budgetary proposals or other
            final proposals from any central bank or other fiscal or monetary
            authority; and

      (b)   would not have arisen but for such assignment or transfer; or

(ii)  if at the time of such transfer or assignment an Event of Default has
      occurred and is continuing unwaived.

29.4  Assignments by Banks  If any Bank assigns all or, save in the case of
the Overdraft Bank, any of its rights and benefits under any of the Finance
Documents in accordance with Clause 29.3 (Assignments and Transfers by Banks),
then, unless and until the assignee has agreed with the Agent, the Arranger,
the Borrower and the other Banks that it shall be under the same obligations
towards each of them as it would have been under if it had been an original
party to the Finance Documents as a Bank (whereupon such assignee shall become
a party to the Finance Documents as a "Bank"), the Agent, the Arranger, the
Borrower and the other Banks shall not be obliged to recognise such assignee
as having the rights against each of them which it would have had if it had
been such a party to the Finance Documents.

29.5  Transfers by Banks  If any Bank wishes to transfer all or, save in the
case of the Overdraft Bank, any of its rights, benefits and/or obligations
under any of the Finance Documents as contemplated in Clause 29.3 (Assignments
and Transfers by Banks), then such transfer may be effected by the delivery to
the Agent of a duly completed and duly executed Transfer Certificate in which
event, on the later of the Transfer Date specified in such Transfer
Certificate and the fifth business day after (or such earlier business day
endorsed by the Agent on such Transfer Certificate falling on or after) the
date of delivery of such Transfer Certificate to the Agent:

      (a)   to the extent that in such Transfer Certificate the Bank party
            thereto seeks to transfer its rights, benefits and obligations
            under any of the Finance Documents, each of the Group Obligors and
            such Bank shall be released from further obligations towards one
            another under any of the Finance Documents and their respective
            rights against one another shall be cancelled (such rights and
            obligations being referred to in this Clause 29.5 as "discharged
            rights and obligations");

      (b)   each of the Group Obligors and the Transferee party thereto shall
            assume obligations towards one another and/or acquire rights
            against one another which differ from such discharged rights and
            obligations only insofar as such Obligor and such Transferee have
            assumed and/or acquired the same in place of such Obligor and such
            Bank;

      (c)   the Agent, the Arranger, such Transferee and the other Banks shall
            acquire the same rights and benefits and assume the same
            obligations between themselves as they would have acquired and
            assumed had such Transferee been an original party to the Finance
            Documents as a Bank with the rights, benefits and/or obligations
            acquired or assumed by it as a result of such transfer; and

      (d)   such Transferee shall become a party hereto as a Term Bank or the
            Overdraft Bank, as the case may be.

29.6  Transfer Fees  On the date upon which a transfer takes effect pursuant
to Clause 29.5 (Transfers by Banks) the Transferee in respect of such transfer
shall pay to the Agent for its own account a transfer fee of  Pound
Sterling750.

29.7  Disclosure of Information

(a)   Save as allowed under Clause 28.14 and 29.7(b), or as requested by any
regulatory authority, bank examiner or statutory auditors, or as required by
an order of any court of competent jurisdiction, or in pursuance to any
procedure for disclosure of documents in any proceedings before any such
court, or pursuant to any law or regulation having the force of law in any
country, the Agent, the Arranger and the Banks shall not, without the
Borrower's prior written consent, disclose any confidential information which
is not at the time of transmission public knowledge made available to it in
relation to any of the Finance Documents save to such of its officers,
employees, agents and advisers as are required in the course of their duties
to receive and consider the same.

(b)   Any Bank may disclose to any actual or potential assignee or Transferee
or to any person who may otherwise enter into contractual relations with such
Bank in relation to any of the Finance Documents such information (the
"Information Material") about the Obligors,  the Group or the ADT Group as
such Bank shall consider appropriate provided that such Bank shall obtain from
the person to whom the Information Material is provided an undertaking to keep
the Information Material secret and confidential and not without the
Borrower's prior written consent, disclose to any third party any of the
Information Material except that (x) such person may disclose the Information
Material to such officers, employees, agents and advisers as are required in
the course of their duties to receive and consider the same, and (y) the
foregoing shall not apply to any disclosure (i) required or requested to be
made to any regulatory authority, bank examiner or statutory auditors; or (ii)
required by an order of any court of competent jurisdiction, or in pursuance
of any procedure for disclosure of documents in any proceedings before any
such court, or pursuant to any law or regulation having the force of law in
any country.

                              THE FIFTH SCHEDULE

                             Associated Costs Rate

1.    For the purposes of this Agreement, the cost of compliance with existing
requirements of the Bank of England in respect of Term Advances denominated in
sterling will be calculated by the Agent in relation to each Term Advance on
the basis of rates to be supplied by each of the Reference Banks by reference
to the circumstances existing on the first day of each Interest Period in
respect of such Term Advance and, if any such Interest Period exceeds three
months, at three calendar monthly intervals from the first day of such
Interest Period during its duration in accordance with the following formula:

             AB + C(B - E) + D(B - F)         per cent. per annum
                   100 - (A + D)

Where:

      A     is the percentage of eligible liabilities which such Reference
            Bank is from time to time required to maintain as an interest free
            cash deposit with the Bank of England to comply with cash ratio
            requirements.

      B     is the percentage rate per annum at which sterling deposits are
            offered by such Reference Bank, in accordance with its normal
            practice, for a period equal to (a) the relevant Interest Period
            (or, as the case may be, remainder of such Interest Period) in
            respect of the relevant Term Advance or (b) three months,
            whichever is the shorter, to a leading bank in the London
            Interbank Market at or about 11.00 a.m. (London time) in a sum
            approximately equal to the amount of such Term Advance.

      C     is the percentage of eligible liabilities which such Reference
            Bank is from time to time required by the Bank of England to
            maintain as secured money with members of the London Discount
            Market Association ("LDMA") and/or as secured call money with
            money brokers and gilt edged market makers.

      D     is the percentage of eligible liabilities which such Reference
            Bank is required from time to time to maintain as interest bearing
            special deposits with the Bank of England.

      E     is the percentage rate per annum at which members of the LDMA are
            offered sterling deposits in a sum approximately equal to the
            amount of the relevant Term Advance as a callable fixture from
            such Reference Bank for such period as determined in accordance
            with B above at or about 11.00 a.m. (London time).

      F     is the percentage rate per annum payable by the Bank of England to
            such Reference Bank on interest bearing special deposits.

2.    For the purposes of this Schedule "eligible liabilities" and "special
deposits" shall bear the meanings ascribed to them from time to time by the
Bank of England.

3.    The percentages used in A, C and D above shall be those required to be
maintained on the first day of the relevant period as determined in accordance
with B above.

4.    In application of the above formula, A, B, C, D, E and F will be
included in the formula as figures and not as percentages e.g. if A is 0.5 per
cent. and B is 12 per cent., AB will be calculated as 0.5 x 12 and not as 0.5
per cent. x 12 per cent.

5.    Calculations will be made on the basis of a 365 day year (or, if market
practice differs, in accordance with market practice).

6.    A negative result obtained by subtracting E from B or F from B shall be
taken as zero.

7.    The arithmetic mean of the resulting figures for each Reference Bank
shall be calculated and shall then be rounded upwards, to five decimal places.

8.    Additional amounts calculated in accordance with this Schedule are
payable on the last day of the Interest Period to which they relate.

9.    The determination of the Associated Costs Rate by the Agent in relation
to any period shall, in the absence of manifest error, be conclusive and
binding on all of the parties hereto.

10.   The Agent may from time to time, after consultation with the Borrower
and the Banks, determine and notify to all the parties hereto any amendments
or variations which are required to be made to the formula set out above in
order to comply with any requirements from time to time imposed by the Bank of
England in relation to Term Advances denominated in sterling (including any
requirements relating to sterling primary liquidity) and, any such
determination shall, in the absence of manifest error, be conclusive and
binding on all the parties hereto.

            might operate to discharge, impair or otherwise affect any of the
            obligations of ADT Limited herein contained or any of the rights,
            powers or remedies conferred upon the Beneficiaries by the
            Facility Agreement or by law.

long as any amounts are or may be owed by any of the Obligors under the
Facility Agreement or any of the Obligors is under any actual or contingent
obligations under the Facility Agreement, ADT Limited shall not exercise any
rights which ADT Limited may at any time have by reason of performance by it
of its obligations hereunder:

      (i)   to be indemnified by the Borrower;

      (ii)  to claim any contribution from any other guarantor of the
            Borrower's obligations under the Facility Agreement; and/or

            subrogation or otherwise) of any rights of the Beneficiaries under
            the Facility Agreement or of any other security taken pursuant to,
            or in connection with, the Facility Agreement by the
            Beneficiaries,

Provided that the restrictions contained in (i) and (ii) above shall only

of when the claim for contribution or indemnification under this Section 2.4
arose.

SECTION 2.5. [Intentionally Omitted]

SECTION 2.6.  Successors, Transferees and Assigns.  This Guarantee shall:

      (a)   be binding upon ADT Limited, and its successors, transferees and
            assigns; and

      (b)   inure to the benefit of and be enforceable by the Agent and each
            other Beneficiary.

Without limiting the generality of clause (b), any Bank may assign or
otherwise transfer (in whole or in part) all or any of its rights or benefits

such rights and benefits, subject, however, to the provisions of the Facility

            hereunder shall be made free and clear of and without deduction
            for or on account of tax unless ADT Limited is required to make
            such a payment subject to the deduction or withholding of tax (not
            being a tax imposed on and/or calculated by reference to the net
            income paid to and received by such person by the jurisdiction in
            which it is incorporated or in which its Facility Office (if any)
            or other relevant office is located), in which case the sum
            payable by ADT Limited in respect of which such deduction or
            withholding is required to be made shall be increased to the
            extent necessary to ensure that, after the making of the
            required deduction or withholding, such person receives and
            retains (free from any liability in respect of any such
            deduction or withholding) a net sum equal to the sum which it
            would have received and so retained had no such deduction or
            withholding been made or required to be made.

      (b)   Tax Indemnity  Without prejudice to the provision of paragraph (a)
            above, if any person or the Agent on its behalf is required to
            make any payment on account of tax (not being a tax imposed on and
            calculated by reference to the net income paid to and received by
            its Facility Office by the jurisdiction in which it is
            incorporated or in which its Facility Office is located) or
            otherwise on or in relation to any sum received or receivable
            hereunder by such person or the Agent on its behalf (including any
            sum received or receivable under this Section 2.7) or any
            liability in respect of any such payment is asserted, imposed,
            levied or assessed against such person or the Agent on its behalf,
            ADT Limited shall, upon demand of the Agent, promptly indemnify
            such person against such payment or liability, together with any
            interest, penalties, costs and expenses payable or incurred in
            connection therewith.

      (c)   Claims by Banks  A Bank intending to make a claim pursuant to
            paragraph (b) above shall notify the Agent of the event by reason
            of which it is entitled to do so, whereupon the Agent shall notify
            ADT Limited thereof  Provided that (i) nothing herein shall
            require such Bank to disclose any confidential information
            relating to the organisation of its affairs and (ii) if a Bank
            notifies the Agent of a claim under Section 2.7(b) after the date
            falling 60 days after the date on which such Bank receives its
            audited annual accounts such Bank shall not be entitled to claim
            indemnification for any event or occurrence which occurred during
            the financial year to which such audited annual accounts relate.

      (d)   Notification of Requirement to Deduct Tax  If, at any time ADT
            Limited is required by law to make any deduction or withholding
            from any sum payable by it hereunder (or if thereafter there is
            any change in the rates at which or the manner in which such
            deductions or withholdings are calculated), ADT Limited shall
            promptly notify the Agent.

      (e)   Evidence of Payment of Tax  If ADT Limited makes any payment
            hereunder in respect of which it is required to make any deduction
            or withholding, it shall pay the full amount required to be
            deducted or withheld to the relevant taxation or other authority
            within the time allowed for such payment under applicable law and
            shall deliver to the Agent for each relevant Bank, within thirty
            days after it has made such payment to the applicable authority
            (or, if later, within 10 business days of receipt), an original
            receipt (or a certified copy thereof) issued by such authority
            evidencing the payment to such authority of all amounts so
            required to be deducted or withheld in respect of that Bank's
            share of such payment.


SECTION 2.8.  Judgment.  ADT Limited hereby agrees that to the fullest extent
permitted by applicable law:

      (a)   if, for the purposes of obtaining judgment in any court, it is
            necessary to convert a sum due hereunder in sterling into another
            currency, ADT Limited agrees that the rate of exchange used shall
            be that at which in accordance with normal banking procedures the
            Agent could purchase Sterling with such other currency on the
            business day preceding that on which final judgment is given; and

      (b)   the obligation of ADT Limited in respect of any sum due from it to
            any Beneficiary hereunder shall, notwithstanding any judgment in a
            currency other than Sterling, be discharged only to the extent
            that on the business day following receipt by such Beneficiary, as
            the case may be, of any sum adjudged to be so due in such other
            currency such Beneficiary may, in accordance with normal banking
            procedures, purchase sterling with such other currency; in the
            event that the sterling so purchased are less than the sum
            originally due to such Beneficiary in sterling, ADT Limited, as
            a separate obligation and notwithstanding any such judgment,
            hereby indemnifies and holds harmless such Beneficiary against
            such loss, and if the sterling so purchased exceeds the sum
            originally due to such Beneficiary in sterling, such Beneficiary
            shall remit to ADT Limited such excess.

SECTION 2.9.  Consent to Jurisdiction; Waiver of Immunities.

      (a)   English Courts - Each of the parties hereto irrevocably agrees for
            the benefit of each of the Beneficiaries that the courts of

            action or proceedings, and to settle any disputes, which may arise
            out of or in connection with this Guarantee (respectively
            "Proceedings" and "Disputes") and, for such purposes, irrevocably
            submits to the non-exclusive jurisdiction of such courts.

      (b)   Appropriate Forum - ADT Limited irrevocably waives any objection
            which it might now or hereafter have to the courts referred to in
            paragraph (a) above being nominated as the forum to hear
            and determine any Proceedings and to settle any Disputes and
            agrees not to claim that any such court is not a convenient or
            appropriate forum.

      (c)   Service of Process - ADT Limited agrees that the process by which
            any Proceedings are begun may be served on it by being delivered
            in connection with any Proceedings in England, to ADT Finance plc
            at 19/21 Denmark Street, Wokingham, Berkshire RG40 2QE or other
            its registered office for the time being.  If the appointment of
            the person mentioned in this  paragraph (c) ceases to be effective
            in respect of ADT Limited, ADT Limited shall immediately appoint a
            further person in England to accept service of process on its
            behalf in England and, failing such appointment within 15 days,
            the Agent shall be entitled to appoint such a person by notice to
            ADT Limited.  Nothing contained herein shall affect the right to
            serve process in any other manner permitted by law.

      (d)   Non-exclusive Submission - The submission to the jurisdiction of
            the courts referred to in paragraph (a) above shall not
            (and shall not be construed so as to) limit the right of the
            Beneficiaries or any of them to take Proceedings against ADT
            Limited 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.

      (e)   Waiver of Immunity - To the extent that ADT Limited may in any
            jurisdiction claim for itself or its assets immunity from suit,
            execution, attachment (whether in aid of execution, before
            judgment or otherwise) or other legal process and to the extent
            that in any such jurisdiction there may be attributed to itself or
            its assets such immunity (whether or not claimed), ADT Limited
            hereby irrevocably agrees not to claim and hereby irrevocably
            waives such immunity in respect of its obligations under this
            Guarantee to the full extent permitted by the laws of such
            jurisdiction.

            other authorisation or to have complied with any of the foregoing
            would not, singly or in the aggregate, reasonably be expected to
            have a material adverse effect on the business, results of
            operations, financial condition or prospects of ADT Limited and
            its subsidiaries taken as a whole;

            similar list or which is the subject of federal, state or local

            leased) by ADT Limited or any subsidiary of ADT Limited which
            would give rise to liability under any Environmental Law or for
            personal injury or property or other damage, which liability could
            reasonably be expected to have a material adverse effect on the
            business, results of operations, financial condition or prospects
            of ADT Limited and its subsidiaries taken as a whole.

SECTION 3.12.  Regulations G, U and X.  Neither ADT Limited nor any subsidiary

            financial condition or prospects of ADT Limited and its
            subsidiaries taken as a whole (it being acknowledged that the

            its corporate existence (except as permitted under Section

                   Subordinated Debt (including Subordinated Debt held by ADT
                   Limited or a Wholly Owned Subsidiary of ADT Limited), would
                   violate the subordination provisions thereof; provided,
                   however, that ADT Limited and its subsidiaries may, to the

                   occur upon giving effect to such payment, prepayment,
                   redemption or repurchase or (y) such payment, prepayment,
                   redemption or repurchase would, pursuant to the terms of
                   the Senior Note Indenture, decrease the Restricted Payment
                   Basket Amount to an amount which is less than the excess of
                   (1) the sum of (A) the aggregate amount expended on
                   Permitted Business Acquisitions (other than the ASH

                   certificate delivered under the guarantees given by ADT
                   Limited in connection with the US$300 million Credit
                   Facility or the US$200 million Credit Facility) delivered in
                   connection with the Financial Quarter in which such Capital
                   Expenditures were paid over (2) the portion (if any) of

We, The Bank of Nova Scotia, acting through its London branch at Scotia House,
33 Finsbury Square, London EC2A 1BB, are pleased to make available to you, in
contemplation of the confirmation of a  Pound Sterling90,000,000 Facility

pending confirmation thereof, a sterling on demand facility on the terms set
forth in this Facility Letter.

them in this paragraph 1(a):

               "Associated Costs Rate" means the rate necessary to cover any
monetary control, liquidity or reserve asset costs where applicable as
determined by us from time to time.

               "Business Day" shall be construed as a reference to a day
(other than a Saturday or Sunday) on which banks generally are open for
business in London.

               "Finance Documents" means (i) this Facility Letter, (ii) the
guarantees of even date herewith entered into by ADT Limited, ADT (UK)
Holdings Limited, Modern Security Systems Limited, ADT Group plc, Electric

favour in respect of your obligations under this Facility Letter, and (iii)
any other agreement, deed, letter, certificate or statement entered into or
provided by you or any Group Guarantor pursuant to the terms thereof or
otherwise in connection therewith.

               "Group Guarantors" means ADT Limited, ADT (UK) Holdings
Limited, Modern Security Systems Limited, ADT Group plc, Electric Protection
Services Limited and Automated Security (Holdings) plc, each of which has
entered into a guarantee of even date herewith in our favour in respect of
your obligations under this Facility Letter.

               "LIBOR" means, in relation to any amount owed by you hereunder
on which interest for a given period is to accrue, the rate per annum
determined by us to be equal to the arithmetic mean (rounded if necessary
upwards to 5 decimal places) of the offered quotations which appear on the
relevant page (as defined in paragraph 1(b)) for such period at or about 11.00
a.m. (London time) on the first day of such period.

               "Loan" means the aggregate principal amount for the time being
outstanding hereunder.

such page or such service shall cease to be available, such other page or such
other service (as the case may be) for the purpose of displaying London
Interbank Offered Rates for such currency as we shall, after consultation with
you, select); and

                (ii)  if no quotation for the relevant period is displayed and
we have not selected an alternative service on which one or more such
quotations are displayed, "LIBOR" shall mean the rate at which we are offering
to prime banks in the London Interbank Market deposits in sterling and for
such period at or about 11.00 a.m. (London time) on the first day of such
period.

be used to give financial assistance (as such term is defined in the Companies

Guarantor) directly or indirectly for any purpose which would be unlawful or
would prejudice in any way whatsoever the validity or enforceability of your
obligations or any of the obligations of the Group Guarantors under any of the
Finance Documents.

      3.  Availability of the Facility

               Subject to Paragraph 4, you may drawdown the facility in one

confirmed to you that we have received all of the documents listed in the

substance, satisfactory to us.  We will promptly give you notice of such
satisfaction.

      5.  Termination

obliged to pay the amount so demanded on such Business Day or if received (or
deemed received) later than 9.30 a.m., on the next succeeding Business Day.

      7.  Interest

           (a)  You shall pay interest on the Loan on the last day of each
interest period at the rate which is the sum of 0.50 per cent. per annum in

another interest period.

           (b)  If you fail to pay any amount when due (in respect of
principal or interest or otherwise), you shall be liable to pay interest on
such unpaid sum upon our demand.  Such interest shall be calculated from the

time and LIBOR on the first day of such periods as we may reasonably select.

immediately in the event that any external indebtedness for borrowed money of
yourself in excess, in aggregate, of Pound Sterling10,000,000 (or its
equivalent) is not paid when due, any such indebtedness of yourself in excess,
in aggregate, of  Pound Sterling10,000,000 (or its equivalent) is declared to
be or otherwise becomes due and payable prior to its specified maturity or any
creditor or creditors of yourself becomes entitled to declare any such
indebtedness of yourself in excess, in aggregate, of  Pound Sterling10,000,000
(or its equivalent) due and payable prior to its specified maturity.

otherwise than on the last day of the interest period relating thereto, you
shall pay us the shortfall (if any) between (i) interest (less 0.50 pr cent.
per annum and Associated Costs Rate) which would have been payable by you on
the repaid amount for the rest of such interest period and (ii) interest on
the repaid amount if re-lent in the London Interbank Market for the rest of
such interest period.

     10.  Costs, Fees and Payments

           (a)  You shall reimburse us on demand for all reasonable expenses
(including legal fees) inclusive of value added tax incurred by us in
connection with the negotiation, preparation and execution of this Facility
Letter and for all expenses (including legal fees) inclusive of value added
tax incurred by us in contemplation of or otherwise in connection with the
enforcement, preservation or protection of any of our rights in respect
thereof.

           (b)  Without prejudice to anything else herein contained you shall
indemnify us on demand against any losses, premium, penalties and expenses
which we may sustain or incur as a consequence of payment of any amount
otherwise than on the due date therefor or in the manner herein prescribed.

and shall be paid in full without set-off or counterclaim.

clear of and without deduction or withholding for any tax or other matter
other than as required by law; if you are required by law to make any
deduction or withholding on account of tax (other than a tax imposed on and
calculated by reference to our overall net income) or otherwise from any such
payment, the sum due from you in respect of such payment shall be increased to
the extent necessary to ensure that, after the making of such deduction or
withholding, we receive a net sum equal to the sum which we would have
received had no deduction or withholding been made.

     12.  No Waiver

               No failure by us to exercise, nor any delay in exercising any
of our rights or remedies hereunder shall operate as a waiver of those rights
or remedies.  Nor shall any single or partial exercise of any right or remedy
prevent any further or other exercise thereof or the exercise of any other
right or remedy.

     13.  Set-Off

               You hereby authorise us to apply any credit balance to which
you are entitled on any of your accounts with us in satisfaction of any sum
due to us by you but unpaid and to purchase sterling with the monies standing
to the credit of any such account if necessary to effect such application.  We
shall not be obliged to exercise our rights under this clause but we shall
confirm any such application which is made by us to you in writing promptly
thereafter.

               Sterling is the currency of account and payment for each and
every sum at any time due from you hereunder.  If for any reason any sum due
from you pursuant to the terms of this letter or any order or judgment given
or made in relation hereto has to be converted from the currency (the "first
currency") in which the same is payable hereunder or under such order or
judgement into another currency ("second currency") for the purpose of (i)
making or filing a claim or proof against you, (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, you shall indemnify us and hold us
harmless 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 we may in the ordinary course of business purchase
the first currency with the second currency upon receipt of a sum paid to us
in satisfaction, in whole or in part, of any such order, judgment, claim or
proof.

withheld or delayed).  However, if at the time of such transfer or assignment,

THIS GUARANTEE (this "Guarantee"), dated as of 3 January 1997, made by ADT
Limited (the "Guarantor") a company organised under the laws of Bermuda of PO
Box 5035, Boca Raton, Florida 33431, USA in favour of The Bank of Nova Scotia
(the "Bank") acting through its London branch at 33 Finsbury Square, London
EC2A 1BB in respect of the obligations of ADT Finance plc (the "Principal") of
19/21 Denmark Street, Wokingham, Berkshire RG40 2QE under a facility letter
(the "Facility Letter") of even date herewith provided by the Bank.



               WITNESSETH as follows:

      1.  Facility Letter Definitions

               Unless otherwise defined herein or the context otherwise
requires, terms used in this Guarantee have the meanings provided in the
Facility Letter.

      2.  The Principal's Obligations

               In this Guarantee the expression "the Principal's Obligations"
means all monies now or at any time hereafter becoming due or owing by the
Principal to the Bank under or pursuant to the Facility Letter.

      3.  Guarantee

          3.1.  In consideration of the Bank entering into the Facility
      Letter, the Guarantor hereby guarantees to the Bank, forthwith on
      demand being made in writing by the Bank on the Guarantor, the
      payment and discharge of the Principal's Obligations.

          3.2.  In the event of, and notwithstanding, the commencement of
      winding up of the Principal, this Guarantee shall extend to and be in
      respect of all monies and liabilities which would have been owing or
      have been incurred by the Principal to the Bank if such event had
      occurred at the time when the Bank makes demand hereunder.

      4.  Indemnity

               For the same consideration the Guarantor hereby agrees as a
primary obligor to indemnify the Bank against any loss which the Bank may
incur in the event of the whole or any part of the Principal's Obligations
being invalid or being or becoming irrecoverable, unenforceable or void or
being avoided for any reason whatsoever, irrespective of whether such reason
was or ought to have been known to the Bank or its officers, employees, agents
or professional advisers.  The amount of such loss shall be the amount which
the Bank would otherwise have been entitled to recover from the Principal.

      5.  Continuing Security

               The Guarantor shall not be entitled to determine this Guarantee
by notice and until the Principal's Obligations shall have been paid or
discharged in full, this Guarantee shall be a continuing security for all the
Principal's Obligations and shall not be discharged by any intermediate
discharge or payment of or on account of the Principal's Obligations or any of
them or any settlement of accounts between the Bank and the Principal or any
other person.  No demand made by the Bank hereunder shall prejudice or
restrict the right of the Bank to make further or other demands.

     6.   Interest

               The Guarantor shall pay interest on any amount for the time
being due from the Guarantor to the Bank under this Guarantee from the date of
a demand for payment hereunder until payment in full, at the rate (as well
after as before judgment) calculated in accordance with Clause 7(b) of the
Facility Letter.

      7.  Representations

               The Guarantor makes the representations and warranties set out
in Clauses 7.1 ad 7.2 and acknowledges that the Bank has entered into
this Guarantee in reliance on those representations and warranties.

          7.1.  The obligations to be assumed by the Guarantor in this
      Guarantee are legal and valid obligations binding on the Guarantor in
      accordance with the terms hereof.

          7.2.  The obligations of the Guarantor under this Guarantee rank at
      least pari passu with its obligations under the guarantee dated 23
      August 1995 (in respect of the credit agreement dated 23 August 1995
      between ADT Operations, Inc. as borrower and the Lenders as defined
      therein) and any guarantee which may be issued by the Guarantor in
      respect of any facility which may replace such credit agreement.

      8.  Opening of New Accounts

               If for any reason this Guarantee ceases to be a continuing
security, the Bank may either continue any then existing account or open one
or more fresh accounts for the Principal, but in either case the obligations
of the Guarantor under this Guarantee shall remain unaffected by, and be
computed without regard to, any payment into or out of any such account after
this Guarantee has ceased to be a continuing security.

      9.  Dealings with the Principal

               The liability of the Guarantor hereunder shall not be impaired,
discharged or otherwise affected by (i) any determination, variation,
discharge, release or increase of, or composition or arrangement relating to
the Principal's Obligations or of or relating to any agreement relating
thereto; or (ii) the grant by the Bank to the Principal or any other person
of any time or indulgence; or (iii) any dealing, exchange, renewal, variation,
release, discharge, compositions, arrangements, modification or abstaining
from perfecting or enforcing or claiming in relation to any securities,
guarantees or rights which the Bank may now or hereafter have in respect to
the Principal's Obligations; or (iv) the Bank's obtaining or failure to obtain
any other guarantee or security (whether contemporaneously with this Guarantee
or otherwise); or (v) any other act, event or omission which but for this
provision would or might operate to impair, discharge or otherwise affect the
obligations of the Guarantor hereunder.

     10.  Discharges and Releases Avoided

               Any discharge or release by the Bank of the Guarantor in
respect of liabilities under this Guarantee or of any security relating
thereto, notwithstanding that this Guarantee may have been returned to the
Guarantor and any agreement between the Guarantor and the Bank concerning any
such liabilities or security shall be void, and deemed to have been given or
entered into by the Bank on the express condition that it would be void, if
any act or thing in reliance upon or on the faith of which the Bank gave such
discharge or release or entered into that agreement shall be subsequently
avoided by or in pursuance of any provision or rule of law.

     11.  Claims of the Guarantor against the Principal

         11.1.  Until the Principal's Obligations shall have been paid or
     discharged in full, and notwithstanding any payment of monies
     recoverable from the Guarantor hereunder or any purported release or
     cancellation of this Guarantee, the Guarantor will not by virtue of
     such payment or by any other means or on any other ground, except with
     the prior written consent of the Bank or as provided below (i) make or
     enforce any claim (whether by way of set-off, counterclaim or
     otherwise) or right against the Principal or prove in competition with
     the Bank, whether in respect of any payment hereunder made by the
     Guarantor or otherwise (other than in the ordinary course of
     business); or (ii) be entitled to claim, or have the benefit of, any
     set-off, counterclaim or proof against, or dividend, composition or
     payment by, the Principal; or (iii) be entitled to claim or otherwise
     obtain the benefit (by way of subrogation or otherwise) of any
     security or guarantee or indemnity at any time held by the Bank for or
     in respect of any of the Principal's Obligations; or (iv) claim or
     enforce any right of contribution against any co-surety; provided that
     the restrictions contained in (i), (ii) and (iv) above shall apply
     only after demand has been made hereunder, but shall apply
     irrespective of when the claim for contribution or indemnity under
     this Clause 11.1 is made.

         11.2.  If the Guarantor shall have any right of proof in the
     winding-up of the Principal which does not derive from a payment made
     hereunder, the Guarantor shall not (except where the Bank otherwise
     requires) exercise that right.

         11.3.  If while the Guarantor shall remain under liability to the
     Bank hereunder, any monies or other property or assets shall be
     received or recovered by the Guarantor in pursuance of any of the
     foregoing provisions of this Clause or in breach of any such
     provisions, such monies or other property or assets shall (save as
     provided herein) be held upon trust to pay or transfer the same to the
     Bank to the extent of such liability.

         11.4.  The Bank shall not be obliged before exercising any of the
rights, powers or remedies conferred upon it in respect of the Guarantor by
any of the Finance Documents or by law:

            (a)   to make any demand of the Principal or any other Group
                  Guarantor;

            (b)   to take any action or obtain judgment in any court against
                  the Principal or any other Group Guarantor;

            (c)   to make or file any claim or proof in a winding-up or
                  dissolution of the Principal or any other Group Guarantor; or

            (d)   to enforce or seek to enforce any other security taken in
                  respect of any of the obligations of the Principal or any
                  other Group Guarantor under any of the Finance Documents;

save that notice of non-payment shall first be given to the Principal provided
that if no such notice is given to the Principal prior to the exercise of such
rights, powers or remedies, that does not preclude the Bank giving notice to
the Principal and thereafter exercising such rights, powers or remedies.

     12.  Set-Off

               Without prejudice to and in addition to any other remedy of
set-off, combination or consolidation of accounts which the Bank may have, at
any time after a demand hereunder the Bank shall be entitled without prior
notice to the Guarantor, if at the relevant time the Principal's Obligations
and all other monies payable hereunder shall not have been fully paid or
otherwise discharged, to set off the liability of the Guarantor hereunder
against any monies in whatsoever currency standing to the credit of the
Guarantor in any current or other account with the Bank and to combine any
such account with any other such account.

     13.  Suspense Account

               The Bank may at any time place and keep to the credit of a
separate suspense account any monies received under this Guarantee for so long
and in such manner as the Bank may determine without any obligation to apply
such monies or any part of them in or towards the discharge of the Principal's
Obligations.  In the event of any proceedings in or analogous to liquidation,
composition or arrangement of or concerning the Principal, the Bank may
notwithstanding any payment made under this Guarantee approve and agree to
accept any dividend or composition in respect of the whole or any part of the
Principal's Obligations in the same manner as if this Guarantee had not been
given.  If and when the aggregate of all monies held on suspense or impersonal
account exceeds the aggregate amount payable by the Principal under the
Finance Documents to the Bank, the Bank shall, as soon as practicable
thereafter, apply any amount held in such suspense or impersonal account in
satisfaction of the amounts payable by the Principal and the Group Guarantors
under the Finance Documents.

     14.  Other Means of Payment

               The Bank may make demand under this Guarantee (i) before making
demand on any other surety or enforcing any other security for the Principal's
Obligations and (ii) for the payment of the ultimate balance after resorting
to other means of payment or for the balance due at any time notwithstanding
that the Bank has not resorted to other means of payment (in which case the
Guarantor shall not be entitled to any benefit from such other means of
payment so long as any of the Principal's Obligations remain outstanding).

     15.  Accounts Settled

               Any accounts settled or stated by or between the Principal and
the Bank may be adduced by the Bank and shall be accepted by the Guarantor as
conclusive evidence (save in the absence of manifest error) of the amount
thereby appearing as due from the Principal to the Bank.

     16.  Payment Free of Deduction

               The Guarantor will pay all monies due under this Guarantee free
and clear of and without deduction for or on account of either any set-off or
counterclaim or any and all present or future taxes, levies, imposts, charges,
fees, deductions or withholdings other than as required by law.  If any sums
payable hereunder shall be or become subject to any deduction or withholding
on account of tax (other than a tax imposed on and calculated by reference to
our overall net income), the amount of such payments shall be increased so that
the net amount received by the Bank shall equal the amount which, but for such
deduction or withholding, would have been received by the Bank hereunder.

     17.  Effectiveness of Security

               This Guarantee is in addition to and is not prejudiced, or to
be prejudiced, by any other guarantee or security for the Principal's
Obligations or any of them which is/are now or may hereafter be held by the
Bank whether from the Guarantor or otherwise.

     18.  Currency Conversions

         18.1.  The Guarantor's liability hereunder shall be to pay the Bank
     the full amount of the Principal's Obligations in each currency in
     which they are for the time being denominated.  Provided that if and
     to the extent that the Guarantor shall not pay such amount in such
     currency the Bank may accept payment of all or part of such amount in
     any other currency and/or require the Guarantor, in substitution for
     its liability to pay such amount in such currency, to pay an amount in
     sterling which is equivalent to the amount of such currency remaining
     unpaid (and in either case the provisions of Clause 18.2 below shall
     apply).


         18.2.  The equivalent on any day in one currency of any amount
     denominated in another currency shall be an amount in the first
     currency equal to the amount which the Bank would have received if the
     Bank had on such day (or, if such day shall not be a business day, on
     the next succeeding business day) made a purchase of the first
     currency with such amount of such other currency at the then
     prevailing spot rate of exchange of the Bank less all costs, charges
     and expenses normally incurred by the Bank or on its behalf in
     connection with such a purchase.

     19.  Costs and Expenses

               The Guarantor shall pay all legal and other costs and expenses
(together with any value added tax or other taxes in respect thereof) incurred
by the Bank in connection with the preservation of rights under and
enforcement of this Guarantee.

     20.  Provisions Severable

               Each of the provisions contained in this Guarantee shall be
severable and distinct from one another and if any one or more of such
provisions is now or hereafter becomes invalid, illegal or unenforceable, the
validity, legality and enforceability of the remaining provisions of this
Guarantee shall not in any way be affected, prejudiced or impaired thereby.

     21.  Benefit and Interpretation of Guarantee

         21.1.  The Bank shall not assign the whole or any part of the benefit
    of this Guarantee without our prior written consent such consent not be
    unreasonably withheld or delayed.  The expression "the Bank" wherever
    used herein shall be deemed to include the assignees and other
    successors of the Bank, who shall be entitled to enforce and proceed
    upon this Guarantee in the same manner as if named herein.  The Bank
    shall be entitled to impart any information concerning the Guarantor to
    any such assignee or other successor or any participant or proposed
    assignee, successor or participant provided that we shall obtain from
    the person to whom such information is provided an undertaking to keep
    such information secret and confidential.

         21.2.  Any reference in this Guarantee to a "person" shall be
    construed as a reference to any person, firm, company, corporation,
    government, state or agency of a state or any association or
    partnership (whether or not having separate legal personality) of two
    or more of the foregoing.

     22.  Notices and Demands

               Any notice or demand to be given or made by the Bank hereunder
may be given to or made of the Guarantor by fax or by letter at its registered
office or principal place of business for the time being.  Any such notice or
demand shall be deemed to be given when despatched (in the case of a
communication made by fax) or (in the case of any communication made by
letter) when left at that address or ( as the case may be) ten days after
being deposited in the post postage prepaid in an envelope addressed to it
at that address.

     23.  Law and Jurisdiction

         23.1.  This Guarantee shall be governed by, and construed in
     accordance with, English law.

         23.2.  The Guarantor hereby agrees for the benefit of the Bank, and
     without prejudice to the right of the Bank to take proceedings in
     relation hereto before any other court of competent jurisdiction, that
     the courts of England shall have jurisdiction to hear and determine
     any suit, action or proceeding that may arise out of or in connection
     with this Guarantee and for such purposes irrevocably submits to the
     jurisdiction of such courts.

                AS WITNESS the hands of the duly authorised representatives of
the parties hereto the day and year first before written.

Notes

(i)     A certain number of common stock equivalents resulting from the
        assumed exercise of executive share options are anti-dilutive in the
        calculation of primary and fully diluted (loss) earnings per common
        share in all years presented.  The effect on primary loss per common
        share resulting from the assumed exercise of the warrant granted to
        Republic, which vested in September 1996, is anti-dilutive in 1996.
        The number of common stock equivalents resulting from the assumed
        exercise of warrants are anti-dilutive in the calculation of primary
