Item 1.  BUSINESS


GENERAL

Newbridge Networks Corporation (the "Company" or "Newbridge") designs,
manufactures, markets and services networking solutions to customers in more
than 100 countries. Newbridge customers include the world's 350 largest service
providers and more than 10,000 corporations, government organizations and other
institutions. The Company was incorporated in June 1986 in Ontario under the
Canada Business Corporations Act.

NETWORKING INDUSTRY

Communications networks may be broadly categorized as local area networks (LANs)
and wide area networks (WANs). As the term suggests, LANs typically cover a
smaller geographic footprint, such as an office floor, a building, or an
enterprise campus, and normally serve the needs of a single corporate user.
WANs, on the other hand cover a broader geographic area in a hierarchical
fashion; for example, a metropolitan area network will connect to a pan-national
network which, in turn, links to a global WAN infrastructure.

Today's communications networks are experiencing unprecedented change, driven by
two principal factors: the Internet and convergence of data, voice and video
traffic. These changes require an overhaul to the existing global public
telecommunications infrastructure as discussed below.

The Internet

The Internet is changing the way we work and live. Internet traffic has been
growing at an exponential rate over the last number of years and this
extraordinary growth has forced service providers and Internet Service Providers
(ISPs) to build their network infrastructures at an unprecedented rate.

The growth in Internet traffic is being driven by a number of factors. As its
value as an information pool and communications/business resource continues to
increase, more and more individuals and companies are going on line.
Additionally, the growing use of the multimedia capabilities of the World Wide
Web has increased the amount of data that needs to be transmitted for the
typical Web page. Multimedia is defined as the combination of multiple media
forms of information. While formats vary and will continue to evolve, they
typically involve elements such as voice, text, graphics, image, video, and
audio. Combinations of these media provide powerful communications tools, but
they are not tolerant of the quality impairing delays associated with "best
effort" Internet protocol (IP) networks based on legacy router technology. Such
next-generation high-bandwidth applications are driving the need for networks
that deliver greater capacity and scalability, performance, quality, and
reliability.

Convergence of Data, Voice and Video Traffic

As the Internet continues to grow in terms of its capabilities, reach and
capacity, the amount of data traffic on the public telecommunications network,
or public switched telephone network (PSTN), as it is known as, now exceeds the
total amount of voice traffic in a growing number of countries throughout the
world. At current growth rates, this will be the case on a global basis

                                    Page 4
<PAGE>

within a few years. This phenomenon, together with the convergence of traffic
types encompassing combinations of voice, video and various forms of data into
multimedia communications packages, and the growth of voice over IP (VoIP),
voice over frame relay (VoFR), voice over asynchronous transfer mode (VoATM), is
leading network engineers with the service providers to plan and design so
called "next generation networks" (NGNs) to handle voice, data, and video
traffic over a single, unifying, broadband multiservice infrastructure.

This converged network infrastructure involves the migration from a highly
centralized, narrowband circuit-switched architecture to a distributed
architecture where the call control and advanced intelligent network (AIN)
functionality reside on intelligent call and service control servers. The
relatively inflexible narrowband circuit switches are being replaced by flexible
broadband packet/cell switches distributed throughout the network. This
transition will occur in stages, with long distance toll or tandem Class 4
switches being the first to migrate, followed by the local or end Class 5
switching centers.

Higher Capacity Backbones

Both traffic carrying requirements and capacity are increasing at every point in
the network hierarchy. Higher bandwidth traffic and capacity within LANs puts
greater capacity pressure on what has traditionally been the first point of
constriction or bottleneck within the public or wide area network, namely the
access portion of the network. New, broadband access technologies, such as cable
modems, various high speed digital subscriber loop technologies (such as ADSL
and SDSL) and broadband wireless access based on LMDS (local multipoint
distribution system) are breaking down the access or "last mile" roadblock.
This, in turn, is putting increasing pressure on the backbone or core of the
network. Where DS-3 (45 Mbit/s or millions of bits per second) connections were
considered adequate only a few years ago, many Internet backbones today are
constructed using OC-3 (155 Mbit/s) links, and these are moving quickly to OC-12
(622 Mbit/s) and OC-48 (2.4 Gbit/s or billions of bits per second) speeds.

Competitive Landscape for Service Providers

The networking industry has seen the birth and growth of a large number of new
service providers, particularly since the mainstream commercialization of the
Internet. The new generation, or "alternate" service providers - including
competitive local exchange service providers (CLECs), competitive access
providers (CAPs), Internet Service Providers (ISPs) and competitive long
distance service providers - coupled with deregulation throughout the industry,
have put increasing pressure on the established service providers. This
competitive challenge requires the established service providers to reduce costs
and optimize network resources, while the growing demand for new communications
services requires them to invest in new infrastructures.

In order to reconcile these conflicting needs, service providers are migrating
the current disparate array of networks and services offered from their networks
onto a single, unifying, broadband infrastructure. The scalability, flexibility,
and inherent quality of service (QoS) of asynchronous transfer mode (ATM)
switching technology make it well suited for multiple traffic types or services,
including delay-sensitive traffic such as real-time voice or video, enabling
service providers to launch new, higher margin, value-added services. At the
same time service providers can lower their up-front and operating costs and
improve the manageability of their overall network infrastructure by
consolidating their present disparate networks onto one ATM-based network.

                                    Page 5
<PAGE>

For example, real-world business case analyses related to the transition from a
narrowband circuit-switched architecture to a broadband packet/cell network
infrastructure estimate that the new solution represents less than half the cost
and one-tenth the space requirements of conventional circuit switches.

BUSINESS STRATEGY

The Company's business strategy is to provide comprehensive, fully managed, end-
to-end wide area networking solutions to service providers and corporate
customers based on a broad product family that cost effectively addresses their
constantly evolving communications requirements. Newbridge products are designed
in accordance with an "evergreen" architecture to provide customers with a
seamless migration and integration path across the entire product family. The
full product family is highly flexible and scalable to meet evolving customer
requirements. Products are software controlled and remotely manageable for ease
of use, efficiency and cost effectiveness. All Newbridge products are designed
to comply with industry standards throughout the world in order to deliver
optimal interoperability and performance in multiprotocol, multivendor networks.

The Company's architectural approach for broadband, multiservice WANs is
directed at providing solutions to issues facing service providers in the core,
edge and access points of the networks. At the core of the WAN, the Company's
strategy focuses on the accelerating deployment of a new core infrastructure
that is highly robust and scalable and capable of supporting various types and
classes of service including "business class" IP. The Company delivers ATM and
IP products for the core of the service provider network to collapse multiple
services onto a single platform. The Company's product strategy also encompasses
the access portion of the network. In addition to a multi-service access server
(MRAS) family of products, the Company provides various access solutions, with a
specific Product Group focussed on this high-end segment of the access market.
Particular areas of focus within broadband access include the relatively new and
rapidly evolving digital subscriber loop (DSL) and LMDS broadband wireless
markets. The Company's product strategy for broadband WANs enables service
providers to compete successfully in the face of increasing competition and
deregulation by reducing capital and operational costs associated with network
infrastructure and creating differentiated, business class service offerings by
delivering multiple services on a single network.

The Company also addresses the enterprise network market with various WAN and
WAN access products based on ATM and TDM technologies and supplements its
network solutions offerings through strategic alliances and other collaborative
undertakings.

The Company extends its business strategy through alliances and strong relations
with a family of over 20 Newbridge Affiliate companies. The Newbridge Affiliate
companies, in which Newbridge owns an equity stake, generally address markets
within the networking industry which are complementary to the Newbridge product
offering. Many of the Newbridge Affiliate companies are addressing opportunities
related to equipment and services for networks optimized for IP traffic. In
March 1996 Newbridge and Siemens formed an alliance encompassing common branding
under the MainStreetXpress banner and joint sales, marketing and customer
service activities.

PRODUCTS

                                    Page 6
<PAGE>

Newbridge has developed a broad family of digital networking products that are
effective in the core, edge and access portions of service provider or corporate
WANs. These products operate under a highly scalable, center-weighted network
and service management system, which is advantageous for large bandwidth-
intensive networks. Newbridge products employ a common architecture that allows
TDM, X.25, frame relay, ATM, SMDS and LAN internetworking to coexist within the
same network and provides a migration path from legacy narrowband to next
generation broadband networks.

The Newbridge family of ATM and IP products includes high performance core, edge
and access switches for service provider networks. Network operators can build
consolidated networks that deliver services for a variety of applications,
employing various forms of access technologies, managed by a single, end-to-end
network and service management system. This approach enables operators to reduce
infrastructure costs and create differentiated service offerings by provisioning
multiple services on a single, unifying, broadband, multiservice network.

The MainStreetXpress 36170 Multiservices Switch is a high capacity platform,
designed to scale from 800 Mbit per second to over 50 Gbit/s. The platform
supports a broad array of services, including native cell relay, frame relay,
circuit emulation for advanced private line services, LAN connectivity, managed
IP services, SMDS services, switched voice services, broadcast-quality video
services, broadband wireless access and other high-capacity access technologies
such as DSL. The modular architecture of the MainStreetXpress 36170 switch
enables network operators to expand from a single-shelf system to a large multi-
shelf system in an as-needed fashion. The high port density of the system
translates into competitive per-port pricing.

The Company's MainStreetXpress product line also includes the MainStreetXpress
36190 Core Services Switch, a high performance ATM backbone or core switch,
designed to scale beyond one terabit (trillion bits) per second, as well as the
MainStreetXpress 36150 Access Switch for premium video service, the
MainStreetXpress 36177 ATM Multiservices Access Switch, the MainStreetXpress
36030 and 36060 Modular LAN Service Units for LAN access and the
MainStreetXpress 36100 Access Concentrator.

TDM products from Newbridge, such as the 3600 and 3645 MainStreet Bandwidth
Managers, are market leading platforms in delivering private line services
throughout the world because of their wide range of voice and data interfaces,
adherence to the full range of domestic and international standards, quality and
reliability, end-to-end and remote network manageability, and flexibility for
seamless expansion and migration as networks grow and applications evolve.

Based on the 3600 MainStreet Bandwidth Manager, the 36120 MainStreet Packet
Transfer Engine frame relay system can be used to deploy frame relay or X.25
networks over a TDM circuit switched network infrastructure. This product
interworks with the Company's TDM and ATM systems for seamless end-to-end,
multiservice network solutions.

Newbridge also addresses the access market segment with products that enable
service providers to deploy multiple services and permit access to those
services for customers with multiple applications. These products include a
variety of WAN access devices for connecting remote and small sites and devices
to extend the network to the end points of both circuit and packet/cell switched
connections.

                                    Page 7
<PAGE>

Newbridge complements products providing connectivity with an extensive suite of
network and service management software products ranging from configuration and
alarm monitoring to interfaces to umbrella management systems and customer
service management systems. The MainStreetXpress 46020 Network Manager provides
unified management of Newbridge and third-party networks across multiple
technologies, including circuit switching, packet/cell switching, SMDS and X.25.
It features a rich, object-oriented graphical user interface (GUI) for efficient
user navigation, and a scalable client/server architecture to provide
simultaneous access for up to 128 operators and cost-effective management for
networks containing up to 5,000 nodes and 100,000 network paths.

Sales of networking products and related services accounted for 100% of the
Company's sales in fiscal 1999, fiscal 1998 and fiscal 1997.

RESEARCH AND PRODUCT DEVELOPMENT

The Company's research and product development activities apply the latest
technologies to the development of advanced functionality in networking hardware
and software. In its product development strategy, Newbridge employs an
"evergreen" approach in which new products and features are designed to
integrate seamlessly with existing products. This approach protects customers'
investment in their installed base of networking equipment. The Company's
research and development strategy also focuses on leveraging product
functionality developed for one market to deliver products addressing other
markets.

In addition to the ongoing evolution of product functionality, a significant
portion of the research and development effort is directed towards expanding the
breadth of network solutions for new value-added service capabilities and access
technologies. Major initiatives include development of higher and lower capacity
ATM multiservice switches and interfaces; development of broadband access
platforms, switches, forwarding engines, interfaces and services optimized for
IP traffic; and related network and service management software. In addition to
the Company's internal research and product development, the Newbridge
development strategy includes investments in affiliated companies developing
networking technology complementary to Newbridge.

The markets for Newbridge products are characterized by rapid technological
change. To maintain its leadership position in advanced networking technologies,
Newbridge is committed to research and development. The Company conducts the
majority of its research and development in a lower cost environment compared
with many competitors. Because of the Company's focus on and commitment to
research and development, coupled with the cost advantages, the Newbridge
strategy has been oriented towards in-house product development. This is in
contrast with some other networking vendors who devote proportionately fewer
resources to research and development and who have more often taken the approach
of obtaining technology and products through the acquisition of other companies.
Newbridge believes that its strategy results in a more cohesive product solution
set for delivering seamless end-to-end networking solutions.

Research and development project schedules for high technology products are
inherently difficult to predict, and there can be no assurance that the Company
will achieve its expected initial shipment dates of products in development.
Because timely availability of new and enhanced products is critical to the
success of the Company, delays in availability of these products, or lack of
market acceptance of such products, could adversely affect the Company.

                                    Page 8
<PAGE>

The Company's ability to anticipate changes in technology, industry standards
and communications service provider offerings, and to develop and introduce new
and enhanced products on a timely basis that are successful in the market, will
be a significant factor in the Company's competitive position and its prospects
for growth.

For additional discussion of the Company's research and development expenditures
in fiscal 1999, 1998 and 1997, see "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

SALES, MARKETING AND DISTRIBUTION

Newbridge sells its products in more than 100 countries. The Company has
established direct sales forces throughout the world, as well as marketing and
distribution arrangements with service providers, original equipment
manufacturers (OEMs), distributors and dealers.

In March 1996, the Company formed an alliance with Siemens which includes common
branding under the MainStreetXpress name for broadband WAN products and joint
sales and marketing efforts. Siemens sells the Company's circuit switched
networking products, ATM products and network and service management products,
primarily to service providers in Europe, Latin America and Asia. Newbridge
products are also distributed throughout the world by AT&T Solutions, Alcatel
and other telecommunications equipment suppliers, as well as by global service
providers and consortia.

The Newbridge sales force in the United States and Canada sells directly to
service providers and other communications service providers. In the United
States, a portion of the direct sales force is focussed on established service
providers including interexchange service providers and Regional Bell Operating
Companies (RBOCs), such as SBC and Bell Atlantic. The other portion of the
direct sales force is dedicated to the emerging alternate service providers.
Newbridge also sells to Fortune 1000 sized companies and institutions,
predominantly through distributors.

The product line is sold throughout Europe, the Middle East and Africa by a
direct sales force as well as through OEMs and distributors. In Latin America
and the Asia Pacific region, networking products are sold primarily through
distributors, which are supported by local Newbridge sales and support offices.
In Latin America, the Company holds a majority equity interest in certain of its
distributors.

The Newbridge sales organization throughout the world receives support from
product line management and network solutions groups which provide product
strategy and consultation on industry trends and pricing, and which solicit
customer feedback for research and product development planning. The Company's
marketing activities are centrally coordinated and emphasize complete network
solutions for the service provider markets (established service providers and
new generation or alternate service providers) and the enterprise network
market.

The amount of sales, cost of sales and expenses, and operating contribution
attributable to the Company's geographically-based operating segments, the
amount of identifiable assets attributable to the Company's principal geographic
regions and the amount of export sales from the Company's operations in Canada
for each of the last three fiscal years are set forth in

                                    Page 9
<PAGE>

Note 20 to the Consolidated Financial Statements. For additional discussion of
the Company's geographic segments, see "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

CUSTOMER SERVICE AND SUPPORT

Reliability, performance, up-time and average mean-time-to-repair are important
factors customers consider in developing long term relationships with potential
suppliers of networking systems. The increasing dependency of many domestic and
international customers upon information networks to run virtually all aspects
of their businesses has generated a demand for a very rapid service response
time. To satisfy this customer demand, the Company offers 24-hour Network
Technical Assistance Centers, complemented by the service support organizations
of the Company's distributors. Because of the remote diagnostic capabilities of
the Company's products, support engineers can immediately begin to diagnose and
solve field problems. When necessary, support engineers are dispatched from the
Company's sales and support offices or by third party technical support service
providers. The Company's standard product warranty covers defects in material
and workmanship and generally applies for 3 to 15 months after shipment.

MANUFACTURING

The principal steps in the manufacturing process are the purchase and management
of materials, assembly, testing and final inspection. Because Newbridge
manufactures and assembles the majority of its products, the Company maintains
direct control over production, quality and product availability. The Company
purchases parts and components for assembly of its products from a large number
of suppliers through a worldwide sourcing program. Although the Company single
sources certain components, no single supplier has accounted for more than 10%
of the Company's total purchases in any of the past three fiscal years.
Newbridge has established strong relationships with key vendors to reduce the
risk of significant shortages or delays relating to availability of materials.
Shortages or delays in the supply of components, however, could adversely affect
the Company's ability to meet scheduled product shipments in any particular
fiscal quarter, which could materially affect the Company's operating results.

The Company currently has its principal manufacturing, logistics and warehousing
facilities in Canada. The Company also has logistics and warehousing facilities
in the United States, Ireland, the United Kingdom, France, Hong Kong, and
Malaysia.

The Company schedules some production of its products based on internal sales
forecasts. The Company's manufacturing procedures are designed to assure rapid
response to customer orders, but may, in certain circumstances, create risk of
excess or inadequate inventory if orders do not match forecast. In the fourth
quarter of fiscal 1999, the Company's revenues were below Management's
expectations, predominantly due to the combination of orders for the Company's
product being skewed towards the end of the quarter, and inadequate inventory of
certain components. Because a substantial portion of customer orders are filled
within the fiscal quarter that they are received and because of the ability of
customers to revise or cancel orders and change delivery schedules without
significant penalty, Management believes that the Company's backlog as of any
given date is not necessarily indicative of actual revenues for any succeeding
period.

COMPETITION

The market for the Company's products is characterized by rapid technological
change, convergence of technologies, mergers and acquisitions of service
providers and equipment suppliers, evolving standards, and regulatory
developments. Many of the Company's competitors and potential competitors have
greater financial, technological, manufacturing, marketing, and personnel
resources than the Company.

The Company's principal competitors include Cisco Systems, Lucent Technologies
and Nortel Networks, as well as traditional circuit switched equipment vendors
such as Tellabs.

Principal competitive factors are product line capabilities including
integration of multiple applications onto a single network, network management
capabilities, ability to offer complete end-to-end networking solutions,
scalability, price, reliability, adherence to standards, and market presence.
Certain competitors, including traditional telecommunications equipment vendors,
such as Ericsson, Fujitsu, Lucent Technologies and Nortel Networks have a very
large installed base in service provider and enterprise networks, some of which
can be upgraded to accommodate new technologies and features.

The networking industry recently has been consolidating through strategic
alliances, mergers and acquisitions thereby creating companies with larger
market shares, financial resources, customer bases, sales forces, product
offerings, research and development and marketing resources. Increasing
competition from larger competitors may adversely affect the Company's business,
particularly with respect to sales and service resources, networking equipment
pricing or vendor financing packages offered to potential customers.


GOVERNMENT REGULATION

The sale of networking products may be affected by governmental regulatory
policies, the imposition of service provider tariffs, and taxation of
telecommunications services, which may also affect the availability of high
capacity digital transmission lines. These policies are under continuous review
and are subject to change.

In the United States, regulatory policies are likely to have a significant
impact on the competitive environment in which the Company operates. The
Telecommunications Act of 1996 and associated regulatory developments is
affecting many regulatory restrictions in the telecommunications market.
Deregulation enables local exchange telephone service providers, RBOCs, long
distance service providers, and other communications service providers, as well
as cable television operators and electric utilities to compete with each other
in offering local and long distance voice and data communications services. In
addition, the RBOCs are now permitted to manufacture and sell telecommunications
equipment under certain conditions. Given the substantial resources and large
customer base of the RBOCs, Newbridge could face competition from these
companies should they satisfy these conditions and elect to manufacture
networking products.

The regulatory environment in the European Union continues to promote
competition for provision of communications services and to open markets for
telecommunications equipment vendors. Member states which have not already fully
liberalized their telecommunications markets by January 1, 1998 are required to
have in place the regulatory and licensing structures that will enable new
operators to enter their markets.

                                    Page 11
<PAGE>

Deregulation is resulting in mergers among the RBOCs and other major
telecommunications companies throughout the world. Although the impact of
mergers that have been announced or are in process cannot be predicted, greater
concentration in the market for telecommunications services could adversely
affect the market for networking products.

Government regulatory authorities have established regulations which, among
other things, set installation and equipment standards for private
telecommunications systems and require that all newly installed hardware be
registered and meet certain government standards. Management believes that the
Company currently complies with, and expects to be able to continue to comply
with these requirements.

PROPRIETARY RIGHTS

The name Newbridge, the Company's corporate logo, and MainStreet are registered
trademarks of the Company in approximately 50 countries. A number of the
Company's other trademarks and service marks are registered in Canada as well as
in various other jurisdictions. The Company also claims rights to a number of
unregistered trademarks, including MainStreetXpress, and other intellectual
property rights. The Company protects its trademarks, inventions, trade secrets,
and other proprietary rights by contract, trademark registration, patent
registration and appropriate trademark and copyright markings, as well as with
internal security. The Company licenses certain intellectual property rights
from third parties. Management believes that the Company's competitive success
will depend primarily on the innovative skills, technical competence and
marketing abilities of the Company's employees.

The Company has entered into technology licenses with other companies, and may
need to continue to do so in the future, because of the existence of the large
number of patents in the networking field, the rapid rate of issuance of new
patents, new standards that may be issued, or to obtain important technology.
Such licenses may impact the Company's operating results.

EMPLOYEES

As of May 2, 1999, the Company had 6,530 employees. None of the Company's
employees is represented by a collective bargaining agreement nor has the
Company ever experienced any work stoppage. Management believes the Company's
relations with its employees are good.


Item 2.  PROPERTIES

The Company owns its corporate headquarters as well as facilities for reasearch
and development, sales and marketing in Kanata, Ontario. The Company also owns
facilities in Newport, Wales for sales, marketing, network services and
logistics and warehousing.

Newbridge leases other facilities in Kanata primarily used for manufacturing
from companies owned by Mr. Terence H. Matthews, Chairman of the Board and Chief
Executive Officer of the Company and its largest single shareholder. In addition
to Kanata, Ontario, the Company also leases logistics and warehouse space in
Rennes, France; Shannon, Ireland; Ogdensburg, New York; Hong Kong and Kuala
Lumpur, Malaysia.

The Company conducts research and development in leased facilities in Rennes,
France; metropolitan London, England; Herndon, Virginia; and Vancouver, British
Columbia. The Company also leases sales and support facilities throughout the
United States and Canada, and

                                    Page 12
<PAGE>

in over 40 locations throughout Europe, the Middle East and Africa, in over 25
locations in the Asia Pacific region, and over 10 locations in Latin America.

Item 3.  LEGAL PROCEEDINGS

In the fourth quarter of fiscal 1998 the Company reached an agreement in
principle to settle the class action lawsuit which was filed in United States
District Court in Washington, D.C. during the fiscal year ended April 30, 1995.
The lawsuit purported to be a class action on behalf of a class of persons who
purchased securities of the Company between March 29 and August 1, 1994 and
alleged that the Company made false and misleading statements in violation of
United States securities law and common law. The Court entered an order and
final judgment approving the settlement and dismissing the lawsuit with
prejudice on October 23, 1998. The Company recorded the expense in connection
with the settlement of $2,642,000 in the fourth quarter of fiscal 1998
representing the direct costs incurred.

Lucent Technologies Inc. ("Lucent Technologies") filed a complaint during the
fiscal year ended April 30, 1998 in United States District Court in Delaware
against the Company and its United States subsidiary, Newbridge Networks Inc.
Lucent Technologies manufactures and sells telecommunications systems, software
and products, and is both a distributor of the Company's products and a
competitor of the Company. The Complaint alleges that the Company's manufacture
and sale, in the United States, of some of the standardized functions on the
Newbridge frame relay and ATM switch products, along with its ADPCM (adaptive
differential pulse code modulation) and card initialization implementations,
infringe certain United States patent rights claimed by Lucent Technologies. The
Complaint requests actual and trebled damages in an unspecified amount. Based
upon its present understanding of the laws in the United States and the facts,
the Company believes it has meritorious defenses to these claims. The Company
has filed an answer to the Complaint and is defending this action vigorously.
Because the outcome of the action is not certain at this time, no provision for
any liability that may result upon adjudication has been made in these
Consolidated Financial Statements.

From time to time, the Company receives notifications that it is or may be
infringing the intellectual property rights of third parties. There can be no
assurance that any such claims or potential claims will not require the Company
to enter into license agreements or result in protracted and costly litigation,
regardless of the merits of such claims. No assurance can be given that any
necessary licenses will be available or that, if available, such licenses can be
obtained on commercially reasonable terms.

Under the provisions of the Investment Canada Act, as amended (the "IC Act"),
the acquisition by non-Canadians, or by corporations in which non-Canadians have
a majority controlling interest, of control of a corporation incorporated in
Canada and carrying on business in Canada is subject to notification and may be
subject to review and approval in certain instances. Given the current value of
the gross assets of the Company, the IC Act requires a non-Canadian who makes an
investment to acquire control of the Company to file an application for review
and obtain an approval.

Dividends

The Company has not paid cash dividends on its Common Shares, and it presently
intends to continue this policy for the foreseeable future in order to retain
earnings for the development of the Company's business.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION

The Company cautions that certain statements in this Report and in the Company's
other periodic reports filed pursuant to the United States Securities Exchange
Act of 1934, as amended (the "Exchange Act"), in "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and elsewhere, may be
forward-looking statements within the meaning of Section 21E of the Exchange
Act, the "safe harbor" for forward-looking statements enacted in the Private
Securities Litigation Reform Act of 1995. The forward-looking statements that
may be contained in the Company's reports under the Exchange Act and in other
oral or written statements made by the Company or by its authorized
representatives involve a number of risks and uncertainties. As a consequence,
actual results might differ materially from results forecast or suggested in
these forward-looking statements. Some of these risks and uncertainties are
identified in the discussion to follow. Additional information regarding these
factors and other important factors that could cause actual results to differ
materially may be referred to as part of particular forward-looking statements.
The forward-looking statements made by the Company or on its behalf are
qualified in their entirety by reference to the important factors discussed
below and to those that may be discussed as part of particular forward-looking
statements.

The Company cautions that the following important factors, among others, could
cause actual results for the fiscal year ending April 30, 2000 and for
subsequent financial reporting periods to differ materially from those forecast
or suggested in any forward-looking statement made by the Company or on its
behalf, in this Report or otherwise. A number of these important factors have
been discussed in this Annual Report on Form 10-K for the fiscal year ended May
2, 1999 and its quarterly reports on Form 10-Q as previously filed with the
United States Securities and Exchange Commission.

Potential Fluctuations in Quarterly Results and Growth Rate

A significant portion of the Company's sales are derived from products shipped
against orders received in each fiscal quarter and from products shipped against
firm purchase orders released in that fiscal quarter. As is prevalent in
emerging segments of the networking industry, a disproportionate amount of the
Company's shipments occur in the third month of each fiscal quarter. As a
result, the Company operates without significant backlog and schedules some
production and budgets expenses based on forecasts of sales, which are difficult
to predict. The Company's manufacturing procedures are designed to assure rapid
response to customer demand, but may, in certain circumstances, create risk of
excess or inadequate inventory if orders do not match forecast. Moreover,
shortages or delays in the supply of manufacturing components at acceptable
prices could adversely affect the Company's ability to meet scheduled product
shipments in any particular quarter, which could materially affect the Company's
operating results. Because a substantial portion of customer orders are filled
within the fiscal quarter of receipt, and because of the ability of customers to
revise or cancel orders and change delivery schedules without significant
penalty, quarter to quarter revenues and, to a greater degree, net earnings, may
be subject to greater variability. Quarterly operating results are consequently
difficult to predict, even towards the end of a given fiscal quarter. The

                                    Page 15
<PAGE>

Company's ability to meet financial expectations may be adversely affected if
the non-linear pattern of shipments from month to month continues.

In addition, the Company is subject to a degree of variation in quarterly sales
as a substantial portion of sales is derived from less mature markets outside of
North America and Western Europe. These markets can be more susceptible to
uncontrollable and changing factors including foreign currency exchange rates,
political or economic conditions in a specific country or region, trade
protection measures, government spending patterns, and other factors. In the
latter part of fiscal 1998, the Company's sales in the Asia Pacific region
declined. Sales in these less mature markets are also often subject to customer
financing, licensing or other import or foreign exchange controls, and other
pre-conditions that can result in requirements to ship orders only if all
components ordered are shipped at the same time ("ship-complete" requirements).
Delays in orders and the Company's ability to fulfill orders with ship-complete
requirements may cause quarter to quarter revenues and, to a greater degree, net
earnings, to be subject to greater variability and less predictability.

In recent fiscal periods, the Company has increased the proportion of revenue
derived from service providers. This market is characterized by large contracts,
although purchases against these contracts will vary from quarter to quarter.

Unforeseen delays in product deliveries or closing large sales, introductions of
new products by the Company or its competitors, seasonal or fiscal patterns of
customer capital expenditures or other conditions affecting the networking
industry in particular or the economy generally during any fiscal quarter could
cause quarterly revenue and, to a greater degree, net earnings, to vary greatly.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business -- Manufacturing".

Technological Changes

The market for the Company's products is characterized by rapid technological
change, evolving industry standards, frequent product introductions and evolving
methods used by service providers and corporations in building and managing
networks. Such changes in the market for networking products may adversely
affect the Company's ability to sell its products. The Company's operating
results will depend in significant part upon its ability to maintain the
competitiveness of its product offerings while reducing unit manufacturing
costs. In fiscal 2000, the Company expects that the demand for networking
products will continue the trend toward ATM, IP, and other packet based
technologies and away from circuit switched networking products.

The Company cautions that its sales may grow at a slower rate in the future than
historical rates of sales growth. The growth of the Company's sales may be
subject to the rate at which service providers deploy service offerings based on
newer technologies such as ATM and IP. Although most network equipment suppliers
have introduced ATM-based product offerings and many service providers have
implemented or announced intentions to implement ATM, the degree of commercial
acceptance of ATM switching technology has not been determined. A key element of
the Company's business strategy is utilizing ATM technology in its network
solutions. Accordingly, the Company's future sales growth and results of
operations are dependent on continued growth and market acceptance of ATM
technology. In addition, quarter to quarter revenues may be subject to greater
variability due to longer sales cycles often associated with the adoption of new
technologies.

                                    Page 16
<PAGE>

The Company's ability to anticipate changes in technology, industry standards
and the evolution in methods of constructing and managing networks, and to
develop and introduce new and enhanced products on a timely basis that are
successful in the market, will be significant factors in the Company's
competitive position and its prospects for growth. Moreover, if technologies or
standards supported by the Company's products or service provider service
offerings based on the Company's products become obsolete or fail to gain
widespread commercial acceptance, the Company's business may be adversely
affected. As a result, Management believes that continued significant
expenditures for research and development will be required in the future.
Research and development project schedules for high technology products are
inherently difficult to predict, and there can be no assurance that the Company
will achieve its expected initial shipment dates of products in development.
Because timely availability of new and enhanced products is critical to the
success of the Company, delays in availability of these products, or lack of
market acceptance of such products, could adversely affect the Company. See
"Business".

Competition and Strategic Alliances

The market for the Company's products is also characterized by intense
competition. The Company competes for customers on the basis of product line
capabilities including integration of multiple applications onto a single
network, network and service management capabilities, ability to offer complete
end-to-end networking solutions, scalability, price, reliability, adherence to
standards, and market presence. An increase in competition could require
increased spending by the Company on research and development and sales and
marketing and may otherwise adversely affect the Company's business. Many of the
Company's competitors and potential competitors have greater financial,
technological, manufacturing, marketing, and personnel resources than the
Company.

The networking industry has been consolidating through mergers and acquisitions
thereby creating companies with larger market shares, financial resources,
customer bases, sales forces, product offerings, research and development and
marketing resources. These larger competitors typically have product lines that
address a broader spectrum of networking requirements, and have greater sales
and services resources to address the market for service providers. Increasing
competition from larger competitors may also adversely affect the Company's
business with respect to networking equipment pricing or vendor financing
packages offered to potential customers. Continued consolidation of the
networking industry could result in a strengthening of the Company's competitors
and may adversely affect the Company's competitive position. See "Business--
Competition".

The Company has an alliance with Siemens, formed to facilitate a coordinated
sales and marketing approach and reseller arrangements. There can be no
assurance that the alliance will lead to competitive products or marketing. In
addition, if this relationship fails to develop as planned, the Company's
business and operating results could be adversely affected.

Acquisitions

The Company's strategy includes acquisitions to enhance its business, diversify
its marketing and distribution, and supplement its product development.
Acquisitions involve numerous risks, including difficulties in the integration
of the operations, technologies and products of the acquired enterprises with
those of the Company, the diversion of management and financial resources to the
task of integration of the respective businesses, the entry into markets in
which

                                    Page 17

<PAGE>

Newbridge has limited direct prior experience and where competitors have
stronger market positions, and the potential loss of key employees of the
acquired enterprises. In view of these challenges, if the Company is unable to
integrate acquired enterprises efficiently and effectively, it may not obtain
the anticipated benefits of acquisitions, and its business and operating results
could be adversely affected. For example, the restructuring costs of
$181,444,000 incurred in fiscal 1998 were attributable largely to the operations
of Ungermann-Bass Networks, Inc. acquired in fiscal 1997. In addition,
acquisitions may affect financial results. For example, in fiscal 1998 the
Company acquired RadNet Ltd. and charged to net earnings $52,762,000 related to
the amortization of purchased research and development in process.

Dependence on Key Employees

The Company's success depends upon the continued contributions of its employees,
many of whom would be difficult to replace. Newbridge believes that its future
success will depend, in significant part, upon its ability to attract, retain
and motivate skilled and talented engineers, sales and marketing personnel, and
management. Competition for such personnel is intense. Failure to attract,
retain and motivate key employees could adversely affect the Company's business
and operating results.

In June 1998 the Company appointed a new President and Chief Operating Officer.
Over the year following the appointment there have been a number of additional
changes in senior management. There are risks inherent in any reorganization,
and the Company can give no assurances that these recent appointments will
ensure that the Company achieves its objectives.

Market Price Volatility of Common Shares

The Company's Common Shares have been subject to substantial market price
volatility, some of which has occurred when there have been variations between
the Company's actual or anticipated financial results and the published
expectations of investment analysts and in the aftermath of public announcements
by the Company and its competitors. In addition, the stock market has
experienced extreme price and volume fluctuations from time to time which have
affected the market price of many technology companies in particular and which
have often been unrelated to the operating performance of these companies. These
broad market fluctuations, as well as general economic and political conditions,
may adversely affect the market price of the Company's Common Shares. Because of
the Company's reliance on stock options as an incentive to its employees,
changes in the market price of the Company's Common Shares could adversely
affect the Company's ability to attract and retain key employees.

Regulation

The sale of networking products may be affected by government regulatory
policies, the imposition of service provider tariffs, and taxation of
telecommunications services, which may also affect the availability of high
capacity digital transmission lines. These policies are under continuous review
and are subject to change. In the United States, regulatory policies are likely
to have a significant impact on the competitive environment in which the Company
operates. The Telecommunications Act of 1996 and associated regulatory
developments is affecting many regulatory restrictions in the telecommunications
market. Deregulation is stimulating increasingly competitive offerings by
communications service providers. In addition, the RBOCs are now permitted to
manufacture and sell telecommunications equipment under certain conditions.
Given the substantial resources and large customer base of the RBOCs,

                                    Page 18
<PAGE>

Newbridge could face competition from these companies should they satisfy these
conditions and elect to manufacture networking products. Notwithstanding the
deregulatory process in the United States and elsewhere, government regulatory
authorities have established regulations which, among other things, set
installation and equipment standards for private telecommunications systems and
require that all newly installed hardware be registered and meet certain
government standards. Service providers also establish standards for
interconnection and integration of network equipment with public switched
telephone networks. Although the Company designs its products to comply with
international standards, to the extent those standards are changed or if the
Company is unable to manufacture standards compliant products on a cost
effective basis, the Company's business may be adversely affected. See
"Business -- Government Regulation" and "Networking Industry".

Proprietary Rights

The Company protects its trademarks, inventions, trade secrets, and other
proprietary rights by contract, trademark registration, patent registration and
appropriate trademark and copyright markings, as well as with internal security.
The Company licenses certain intellectual property rights from third parties.
There can be no assurance that the steps taken by the Company to protect its
intellectual property rights will be adequate to prevent misappropriation of its
technology or that the Company's competitors will not independently develop
technologies that are substantially equivalent or superior to the Company's
technology. In addition, some foreign countries do not have or enforce laws that
protect the Company's intellectual property rights to the same extent as do the
laws of the United States and Canada.

The Company is subject to the risk of adverse claims and litigation alleging
infringement of the intellectual property rights of others. From time to time
the Company has received claims of infringement of other parties' proprietary
rights, and has been sued by Lucent Technologies as described in "Legal
Proceedings". There can be no assurance that third parties will not assert
infringement claims in the future with respect to the Company's current or
future products or that any such claims will not require the Company to enter
into license agreements or result in protracted and costly litigation,
regardless of the merits of such claims. No assurance can be given that any

Foreign Currency Exposure and Concentration of Credit Risk

Because substantial portions of the Company's sales, cost of sales and other
expenses are denominated in U.S. dollars and Pounds Sterling, the Company's
results of operations are subject to change based on fluctuations in the rates
of exchange of those currencies for the Canadian dollar. The Company uses
financial instruments, principally forward exchange contracts, in its management
of foreign currency exposures. Realized and unrealized gains and losses on
foreign exchange contracts are recognized and offset foreign exchange gains and
losses on the underlying net asset or net liability position. These contracts
primarily require the Company to purchase and sell certain foreign currencies
with or for Canadian dollars at contractual rates. Several major financial
institutions are counterparties to the Company's financial instruments. It is
Company practice to monitor the financial standing of the counterparties and
limit the amount of exposure to any one institution. The Company may be exposed
to a credit loss in the event of nonperformance by the counterparties to these
contracts. With respect to accounts receivable, concentration of credit risk is
limited due to the diverse areas covered by the Company's operations. The
Company has credit evaluation, approval and monitoring processes intended to
mitigate potential credit risks. Anticipated bad debt loss has

                                    Page 19

been provided for in the allowance for doubtful accounts. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Quantitative and Qualitative Disclosures About Market Risks".

Other Factors

The Company further cautions that the factors referred to above and those
referred to as part of particular forward-looking statements may not be
exhaustive, and that new risk factors emerge from time to time in its rapidly
changing business. The Company does not undertake to update any forward-looking
statements it may make or has made on its behalf to reflect changes in its
expectations or assumptions or the risks and uncertainties referred to.

CERTAIN TAX CONSIDERATIONS

The following discussion outlines Canadian and United States federal income tax
consequences of ownership of the Company's Common Shares that could be relevant
for persons who are not residents of Canada.

Gains on Disposition of Common Shares

Under the provisions of the 1980 Convention between Canada and the United States
with respect to Taxes on Income and on Capital, as amended by the 1983, 1984,
1995 and 1997 Protocols thereto (the "Convention"), United States corporations
or individual residents of the United States ("U.S. Shareholders") that do not,
and are not deemed to, use or hold the Common Shares in carrying on a business
in Canada ("Unconnected U.S. Shareholders") generally will not be subject to
Canadian federal income tax on any capital gain recognized upon the disposition
of their Common Shares, provided that the value of the Common Shares is not
derived principally from real property situated in Canada, as determined at the
time of their disposition. The Company is of the view that the Common Shares
currently do not derive their value principally from such real property.

For United States federal income tax purposes, an Unconnected U.S. Shareholder
generally will recognize a capital gain or loss on the disposition of Common
Shares in an amount equal to the difference between the amount realized upon the
disposition and the U.S. Shareholder's adjusted basis in the Common Shares.
Capital losses are deductible to the extent of capital gains and, in the case of
non-corporate U.S. Shareholders, may be used to offset up to US$3,000 of
ordinary income (US$1,500 in the case of married individuals filing separately).

Taxation of Dividends

Dividends paid to Unconnected U.S. Shareholders owning less than 10% of the
voting shares of the Company generally are subject to Canadian withholding tax
at the reduced rate of 15% under the Convention. In the case of a corporate
Unconnected U.S. Shareholder owning 10% or more of such shares, the withholding
tax rate generally is reduced to 5% under the Convention.

Unconnected U.S. Shareholders generally will treat the gross amount of dividends
paid by the Company, without reduction for Canadian withholding taxes, as
ordinary taxable income for United States federal income tax purposes. In
certain circumstances, however, Unconnected U.S. Shareholders may be eligible to
receive a foreign tax credit for such taxes and, in the case of a corporate
Unconnected U.S. Shareholder owning 10% or more of the voting shares of the
Company, for a portion of the Canadian taxes paid by the Company itself.
Dividends paid by the Company to United States corporations will not, however,
give rise to the dividends

                                    Page 20

received deduction generally allowed those corporations under United States
federal income tax law.

Sales grew in fiscal 1999 compared to fiscal 1998 due to increased sales volume
of products based on packet technologies for wide area network applications (WAN
Packet products) offset in part by a decline in revenues from products based on
packet technologies for local area network applications (LAN Packet products).
Sales grew in fiscal 1998 compared to fiscal 1997 due to increased sales volume
of both WAN Packet and LAN Packet products, offset in part by a decline in sales
of circuit switched networking products.

</TABLE>

Growth in sales of WAN Packet products was predominantly the result of increased
acceptance and demand by service providers throughout the world for the
Company's asynchronous transfer mode (ATM) products.

Sales of circuit switched networking products have been and are expected to be
subject to potential declines and quarterly variability as customers throughout
the world increasingly adopt packet technologies.

LAN Packet product revenues declined in fiscal 1999 relative to fiscal 1998 as a
result of sharp decreases in revenue derived from products associated with the
former Ungermann-Bass Networks Inc. ("UB") organization, which the Company
acquired in January 1997. The

                                    Page 24
<PAGE>

Company restructured its activities in the LAN business, including the former
UB, in the third quarter of fiscal 1998 and instituted an end of life program in
the second quarter of fiscal 1999 to discontinue the sale and development of LAN
Layer 2 Switching products. In fiscal 1998 and in fiscal 1997 LAN Packet product
revenues increased, mainly as a result of the purchase of UB.

The Company expects the proportion of sales derived from WAN Packet products to
continue to increase relative to sales derived from circuit switched networking
products in fiscal 2000 when compared to fiscal 1999. Sales growth, however, may
be impeded due to longer sales cycles often associated with the adoption of
newer, less established technologies.

The Company sells its products to service providers for applications that
provide a range of value-added services, such as Virtual Private Networks
(VPNs), wide area network support and Internet access, and for resale to end
users. Deliveries to original equipment manufacturers (OEMs) for service
provider customers and deliveries under certain large contracts with service
providers contributed significantly to sales in fiscal 1999, fiscal 1998 and
fiscal 1997. Sales to Siemens AG and subsidiaries were generally under OEM
arrangements for resale to end users. Sales to service providers and enterprises
as a percentage of total sales and the proportion of sales to Siemens AG were as
follows.

 </TABLE>

The proportion of revenue derived from service providers in fiscal 1999
increased relative to fiscal 1998 due to the decline in revenues of former UB
Networks products, which largely serve enterprise customers. The proportion of
revenue derived from service providers in fiscal 1998 increased relative to
fiscal 1997 primarily as a result of increased acceptance and demand by service
providers for the Company's WAN Packet products.

consolidated sales derived by sales management in each of the principal
geographic regions in which the Company operates.

</TABLE>

Sales increased in fiscal 1999 relative to fiscal 1998 in both the Americas
Region and the European Region, although sales decreased in the Asia Pacific
Region during the same period as a result of a downturn in economic activity in
that region. For additional geographic segment information, see Note 20 to the
Consolidated Financial Statements.

Because substantial portions of the Company's sales, cost of sales and other
expenses are denominated in U.S. dollars and Pounds Sterling, the Company's
results of operations are subject to change based on fluctuations in the rates
of exchange of those currencies for the Canadian dollar. The decrease in
exchange rates of the Canadian dollar for the Pound Sterling and the U.S. dollar
during fiscal 1999, relative to exchange rates during fiscal 1998, resulted in a
6% or $91,248,000 positive variance in reported sales as compared to fiscal
1998. The decrease in exchange rates of the Canadian dollar for the Pound
Sterling and the U.S. dollar during fiscal 1998, relative to exchange rates
during fiscal 1997, resulted in a 7% or $95,736,000 positive variance in
reported sales as compared to fiscal 1997. As substantial portions of the
Company's cost of sales and other expenses are also incurred in U.S. dollars and
Pounds Sterling, the variations in rates of exchange did not result in a
material variance in net earnings for fiscal 1999, fiscal 1998 or fiscal 1997.
For information related to the Company's policies in its management of foreign
exchange exposures, see "Quantitative and Qualitative Disclosures About Market
Risk" and Note 10 to the Consolidated Financial Statements.

The Company derives a significant portion of its sales from products shipped
against orders received in each fiscal quarter and from products shipped against
firm purchase orders released in that fiscal quarter. As is prevalent in
emerging segments of the networking industry, a disproportionate amount of the
Company's shipments occur in the third month of each fiscal quarter. In
addition, customers have the ability to revise or cancel orders and change
delivery schedules without significant penalty. As a result, the Company
operates without significant backlog and schedules some production and budgets
expenses based on forecasts of sales, which are difficult to predict. Unforeseen
delays in product deliveries or closing large sales, introductions of new
products by the Company or its competitors, seasonal patterns of customer
capital expenditures or other conditions affecting the networking industry in
particular or the economy generally during any fiscal quarter could cause
quarterly revenue and, to a greater degree, net earnings, to vary greatly.
Quarterly operating results are consequently difficult to predict, even towards
the end of a given fiscal quarter.

The Company may become subject to sales fluctuations toward the end of calendar
1999 as the issue of Year 2000 date compliance may influence customer buying
patterns. Sales mix shifts may occur due to customers limiting their purchases
of networking equipment to products that they have already tested for Year 2000
Compliance within their networks, which would shift sales mix away from emerging
product offerings and software upgrades. Sales declines could result if
customers decide to delay expansion of their networks to after January 1, 2000.
The majority of the Company's current product offerings have Year 2000 Compliant
versions available and all emerging offerings are designed to be Year 2000
Compliant, so the Company does not anticipate significant sales fluctuations
associated with Year 2000 date compliance. The Company will have a better
indication of potential fluctuations in the second half of calendar 1999. Refer
to the "Year 2000 Date Compliance" section of this report for a summary of the
Company's program for ensuring that all of its products are Year 2000 date
compliant.

</TABLE>

Cost of sales consists of manufacturing costs, warranty expense and costs
associated with the provision of services. The gross margin as a percentage of
sales declined in fiscal 1999 relative to fiscal 1998 due to the continuing
shift in the mix of sales from higher gross margin circuit switched networking
products to lower margin WAN Packet products. In addition, the gross margin,
expressed as a percentage of sales, was negatively impacted by lower average
selling prices as the Company experienced increased competition on product
pricing, particularly in the market for products based on packet technologies.

The decline in the gross margin as a percentage of sales in fiscal 1998 relative
to fiscal 1997 was primarily the result of the decline in revenues from circuit
switched networking products, which carried gross margins above the average
gross margins earned on the Company's other products.

The impact on product pricing of increased competition, particularly in the
market for products based on packet technologies, may constrain the Company's
ability to maintain gross margins with reductions in per unit costs. As a
result, the gross margin as a percentage of sales may deteriorate in fiscal 2000
compared to fiscal 1999.

</TABLE>

Selling, general and administrative expenses increased in fiscal 1999 relative
fiscal 1998 principally as a result of increased remuneration costs associated
with salary increases and the addition of sales, marketing and technical support
personnel. Other increases in fiscal 1999 relative to fiscal 1998 included
amortization costs associated with upgrading information technology
infrastructure, and increased marketing costs related to the introduction of new
products and expanded advertising programs.

                                    Page 27
<PAGE>

The decrease in selling, general and administrative expenses as a percentage of
sales in fiscal 1999 relative to fiscal 1998 resulted from the lower percentage
increase in expenditures as compared to the larger percentage increase in
revenues over the same period. Management anticipates that selling, general and
administrative expenses as a percentage of sales will continue to decline in
fiscal 2000 relative to fiscal 1999.

The increase in selling, general and administrative expenses as a percentage of
sales in fiscal 1998 over fiscal 1997 reflects the higher cost structure of
companies acquired during fiscal 1997 and the impact of sequential sales
declines in the first three quarters of fiscal 1998.

</TABLE>

Research and development expenditures consist primarily of software and hardware
engineering personnel expenses, costs associated with equipment and facilities,
and subcontracted research and development costs. The sequential increases in
gross research and development expenditures in fiscal 1999 and fiscal 1998
reflect spending on the development of higher and lower capacity ATM switches
and interfaces, development of switches, forwarding engines, interfaces and
services for IP traffic, and related network management and service software.
The majority of the increase resulted from salary increases for engineering
staff and increased amortization associated with capital deployed in research
and development.

Recoveries increased as a percentage of gross expenditures in fiscal 1999
compared to fiscal 1998 due to an increase in customer, government and other
funding. The increase in customer, government and other funding is mainly as a
result of funding secured for the Company's broadband wireless access product
initiative, as described in Note 13 to the Consolidated Financial Statements.
Management expects the level of recoveries, as a percentage of gross research
and development expenditures, in fiscal 2000 to approximate or exceed the level
in

                                    Page 28
<PAGE>

fiscal 1999 based on current levels of committed customer, government and other
funding relative to planned spending levels.

Recoveries decreased as a percentage of gross expenditures in fiscal 1998
compared to fiscal 1997 due to declines in investment tax credits and in
customer, government and other funding as a proportion of gross research and
development expenditures.

The markets for the Company's products are characterized by continuing
technological change. The Company plans to increase gross research and
development expenditures in fiscal 2000 relative to fiscal 1999 to address the
requirements of service providers as they invest in new infrastructures to meet
the challenges of growing demand for new communications services and increased
competition.

In April 1999, the Company decided to streamline the operations of regional
sales and support organizations as well as its marketing and product development
organizations. The restructuring costs associated with the sales, support and
marketing organizations ("Sales and Marketing") consisted primarily of costs
related to workforce and facilities reductions, as the Company has announced a
reduction in the number of locations in which it will have a physical presence
in favour of distributors in certain markets, and subcontractors for certain
functions. Restructuring costs associated with product development relate
primarily to asset impairment losses related to the capping, discontinuation or
divestiture of the development of certain products, and the centralization of
development laboratories to make the development process more efficient.
Restructuring costs of $73,570,000 comprise the following:

All of the amounts listed in the provision for restructuring are reflected in
accrued liabilities as at May 2, 1999.

The provision for the reduction in work force includes severance, related
medical and other benefits, and other obligations to employees. The provision
includes termination benefits for approximately 200 employees. The work force
reductions will occur in Japan, Russia and various other countries. The Company
anticipates that these work force reductions will be substantially completed in
the first half of fiscal 2000.

The provision for the reduction in facilities comprises primarily lease payments
and fixed costs associated with the closure of sales, support and administrative
facilities in Europe, Japan and the United States. The Company expects to
complete these facilities closures in the first half of fiscal 2000.

The provision for other restructuring costs comprises professional fees and
other various direct incremental costs associated with the restructuring plan.

In October 1998, the Company decided to discontinue the sale and development of
local area network (LAN) Layer 2 Switching products as part of the enhancement
of the focus on the Company's dominant and more profitable products. This
program, substantially complete at the end of fiscal 1999, created impairment
losses associated with certain assets deployed in this business and obligations
related to fulfilling previous customer commitments.

In October 1998, the Company commenced relocating certain employees and
activities that support the Asia Pacific region from Kanata, Ontario to Hong
Kong and Malaysia in order to provide more efficient and cost effective services
to customers in that region. The charge of $6,532,000 incurred in October 1998
reflects the accrual of involuntary termination benefits, lease cancellation
penalties and other direct costs associated with the transition. As at May 2,
1999, $1,215,000 of these costs had been incurred. Additional costs related to
the transfer of personnel and equipment, the recruitment of new staff and the
expansion of facilities in Hong Kong are being expensed as incurred. These
additional costs, estimated at $9,000,000, were not significant in fiscal 1999
with the majority of the costs to be incurred during the first two quarters of
fiscal 2000.

In November 1997, the Company restructured its activities relating to its LAN
business.  The restructuring plan involved the formation of an alliance with a
company strongly positioned in the LAN business, and the reduction of the
Company's direct participation, and related costs, in the LAN business. In
repositioning the way in which the Company addressed the LAN market, the
restructuring plan created impairment losses on certain assets associated with
the LAN business and liabilities associated with restructuring activities.
Accordingly, the Company recognized restructuring costs of $181,444,000 in the
third quarter of fiscal 1998. The restructuring plan is completed.

Purchased Research and Development In Process

In November 1997, the Company acquired a 49.9% equity interest in RadNet Ltd.,
an Israeli developer and manufacturer of access switches for ATM networks, for
cash consideration of $53,676,000. The majority of the purchase price
($52,762,000) was allocated to purchased research and development in process.
Under accounting principles generally accepted in Canada, the

                                    Page 30
<PAGE>

purchased research and development in process was amortized on a straight line
basis over its estimated useful life of six months. Accordingly, the Company
recorded amortization of $52,762,000 in fiscal 1998.

The Company capitalized purchased research and development in process of
$96,940,000 in fiscal 1997 related to the acquisition of UB Networks. The
Company reviewed the recoverability of the purchased research and development in
process during the fourth quarter of the fiscal 1997, and determined that it no
longer met all the criteria for deferral, which resulted in the balance being
written off as a charge to net earnings.

</TABLE>

Interest income earned in fiscal 1999 increased as compared to fiscal 1998 due
to an increase in the average cash position maintained by the Company. The
primary contributors to the increase in the cash position were proceeds received
from the sale of long term investments and proceeds from the issuance of Senior
Notes in April 1998. Interest income earned in fiscal 1998 decreased as compared
to fiscal 1997 due to declines in the cash position maintained by the Company
and due to declines in interest rates earned on investments. Interest expense on
long term obligations increased in fiscal 1999 relative to fiscal 1998 and
fiscal 1997 primarily due to the issuance of US$225,000,000 in Senior Notes in
April 1998. Other expenses increased in fiscal 1999 relative to fiscal 1998 and
fiscal 1997 primarily as a result of the Company's equity share of its affiliate
companies losses.

In December 1998, the Company sold its minority ownership position in Cambrian
Systems Corporation ("Cambrian") to Northern Telecom Limited ("Nortel") for cash
proceeds of US$95,674,000 (Cdn$147,158,000). The proceeds include an earn-out
payment of US$1,935,000 (Cdn$2,855,000) received by the Company as a result of
certain specified financial performance targets being met by Cambrian. The
proceeds exclude future potential earn-out payments of approximately
US$21,000,000 which will be received by the Company if certain specified
financial performance targets are met by Cambrian.

In October 1998, the Company completed the sale of its majority ownership
position in Advanced Computer Communications ("ACC") to Telefonaktiebolaget LM
Ericsson for cash proceeds of US$167,319,000 (Cdn$258,308,000). ACC's results of
operations were consolidated with the Company's results for the first six months
of fiscal 1999 ended November 1, 1998. The results of operations and the
financial position of ACC were not significant relative to the Company's
consolidated results of operations and financial position for all periods
presented.

In December 1998, the Company sold its minority ownership position in Vienna
Systems Corporation to Nokia Corporation for cash proceeds of $39,716,000.

In February 1999, the Company sold a portion of its minority ownership position
in Tundra Semiconductor Corporation for cash proceeds of $19,498,000 as part of
an initial and secondary share offering by Tundra.

In January 1998, the Company sold its minority interest in Broadband Networks
Inc. to Nortel for proceeds of $66,672,000.  The proceeds received included cash
of $23,775,000 and Nortel shares valued at $42,897,000.

On February 10, 1999 West End Systems Corp., a manufacturer of access and
transmission products for the communications and cable television industries,
filed an assignment in bankruptcy under the Canadian Bankruptcy and Insolvency
Act.  As a result, the Company recorded losses related to the Company's minority
ownership position in West End Systems Corp. and unsecured trade accounts
outstanding.

The Company evaluates, on an ongoing basis, the value of its long term
investments considering the evolution of the market segments of investee
companies, any impact of

                                    Page 32
<PAGE>

deteriorating economic conditions in various countries, and any other specific
information which indicates impairment of value of these investments. In fiscal
1999, the financial performance of certain investee companies as well as
deteriorating economic conditions in Brazil and Russia led to investment
impairment write downs of $65,431,000.

  Income tax rate excluding
     non-recurring gains and charges      30%         30%         31%
</TABLE>

The income tax rates for fiscal 1999, fiscal 1998 and fiscal 1997 differ from
the income tax rates, excluding non-recurring gains and charges, due to limits
on the deductibility of certain elements of restructuring costs recorded in
fiscal 1999 and fiscal 1998 and purchased research and development in process
recorded in fiscal 1998 and fiscal 1997. The composite rates of income tax,
excluding non-recurring gains and charges, for fiscal 1999, 1998 and 1997 were
reduced from the statutory rate primarily as a result of the application of
certain deductions related to manufacturing and processing activities and to
research and development expenditures in Canada. Future changes in the composite
rates of income tax will be primarily due to the relative profitability of
operations and the national tax policies in each of the various countries in
which the Company operates. Management believes that the composite rate of
income tax, excluding non-recurring gains and charges, will remain lower than
the statutory rate because of the deductibility related to manufacturing and
processing activities and research and development expenditures in Canada as
well as other tax planning measures undertaken by the Company. See Note 17 to
the Consolidated Financial Statements.

Non-Controlling Interest

The non-controlling interests' share of net earnings in fiscal 1999, fiscal 1998
and fiscal 1997 represented less than 1% of the Company's sales in fiscal 1999,
fiscal 1998 and fiscal 1997. The non-controlling interests' share of net
earnings in fiscal 1997 of $5,118,000 related primarily to profits from the
operations of Transistemas S.A., an Argentine systems integrator of networking
products. As at May 2, 1999 there are non-controlling interests in three of the
Company's subsidiaries. All three of these subsidiaries are systems integrators
of networking products in Latin America.

Reconciliation of Financial Results to United States Accounting Principles

The Consolidated Financial Statements have been prepared in accordance with
accounting principles generally accepted in Canada ("Canadian GAAP"). These
principles are also generally accepted in the United States ("U.S. GAAP") in all
material respects except for the disclosure of certain cash equivalents on the
Consolidated Balance Sheets and investing activities on the Consolidated
Statements of Cash Flows, as disclosed in Note 2, the write off of purchased in
process research and development, as disclosed in Note 15, and the method of
calculation of earnings per share, as disclosed in Note 18. Other than the
accounting treatment associated with any future acquisitions or mergers, the
Company expects that the differences in future years will not be significant.

Financial Condition

During the fiscal year ended May 2, 1999 working capital increased from
$945,892,000 to $1,243,991,000. As at May 2, 1999 the Company had $879,694,000
of cash and cash equivalents, which represented an increase of $380,416,000
during fiscal 1999. The most significant contributing item to the increase in
cash and cash equivalents in fiscal 1999 was proceeds from the sale of long term
investments, which amounted to $456,966,000 (see Note 16 to the Consolidated
Financial Statements). A summary of the major cash flow components by activity
is as follows.

Principal components of the Company's working capital are accounts receivable,
inventory, and accounts payable. Management believes that the payment terms and
conditions extended to the Company's customers, arrangements with the Company's
suppliers, and the levels of inventory the Company carries relative to its
levels of sales are consistent with practices generally prevailing in the
networking industry. Accounts receivable, as a proportion of revenue, remained
consistent in fiscal 1999 as compared to fiscal 1998. Inventory turns improved
during the year from 3.2 times in fiscal 1998 to 3.6 times in fiscal 1999.

In April 1998 the Company issued US$225,000,000 Senior Notes due April 2003
bearing a coupon rate of 6.51%. The Senior Notes require semi-annual payments of
interest only, with the principal due at maturity. The Company's obligation
under the Senior Notes can be satisfied at any time prior to maturity subject to
a make whole provision. The Senior Notes are unsecured.

In January 1998 the Company entered into and received $50,000,000 under a long
term loan agreement. The loan agreement includes a term loan portion and a
demand loan portion, both

                                    Page 36
<PAGE>

due January 2003. The term loan bears interest at the fixed rate of 5.46% and
the demand loan bears interest at a floating rate equal to the one month's
bankers' acceptance rate. The term loan requires semi-annual payments of
interest only, with the principal due at maturity. The Company's obligation
under the term loan can be satisfied at any time prior to maturity subject to a
make whole provision. The term loan is secured by 654,220 Nortel shares. The
demand loan, which is unsecured, requires monthly payments of interest only,
with the principal due at maturity.

Existing short term bank credit facilities consist of operating lines of credit
with certain banks in the aggregate amount of $156,258,000, primarily with banks
in Canada, the United Kingdom, the United States and Chile. At May 2, 1999
$5,881,000 was being utilized under these credit facilities, primarily
attributed to non-wholly owned subsidiary Coasin S.A.

During fiscal 1999 and fiscal 1998 the Company generated cash proceeds of
$456,966,000 and $66,672,000, respectively, on the sale of equity positions in
the following companies. Details of each transaction are described in Note 16 to
the Consolidated Financial Statements.

</TABLE>

Capital expenditures for fiscal 1999 of $213,903,000 declined as compared to
those of fiscal 1998 ($276,778,000) because there was no major facilities
expansion cost incurred during fiscal 1999. Capital expenditures for fiscal 1998
exceeded those of fiscal 1997 as the Company invested in new facilities in
Canada, in land in the metropolitan area of Washington, D.C., in research and
development and manufacturing equipment and in information systems. Management
anticipates that the level of capital expenditures for fiscal 2000 will be
approximately consistent with the level of capital expenditures incurred in
fiscal 1999. The Company may also increase its current investments in associated
companies. The Company intends to fund capital expenditures and investments with
existing cash and cash expected to be generated from operations during fiscal
2000, supplemented as appropriate by divestitures or the issuance of shares or
debt. In addition, the Company may use a portion of its cash resources to extend
or enhance its business and diversify its marketing and distribution channels
through acquisitions of or investments in businesses, products or technologies
or through the formation of strategic partnerships with other companies.

Management believes that the Company's liquidity in the form of existing cash
resources, its credit facilities, as well as cash generated from operations and
financing activities, will prove adequate to meet its operating and capital
expenditure requirements through the end of fiscal 2000 and into the foreseeable
future.

Management believes that inflation did not have a material effect on operations
during the fiscal year ended May 2, 1999.

Recent Developments

In May 1999, the Company completed its investment in TeraBridge Technologies
Corporation ("Terabridge"), which specializes in delivering intelligent call and
service control products to service providers and is headquartered in Gurnee,
Illinois. The Company acquired a 19% equity ownership position for US$60,000,000
(Cdn$90,511,000) and has an option to increase its equity ownership position to
50% for US$10,000,000.

In June 1999, the Company announced a definitive agreement to acquire Stanford
Telecommunications Inc. ("STII") (STII: NASDAQ), a leading supplier of broadband
wireless technology and products. The net purchase price of the acquisition is
estimated at US$280,000,000 (Cdn$ 411,740,000) which represents the gross
purchase price of approximately US$490,000,000 (Cdn$720,545,000) net of proceeds
from the divestiture of divisions of STII that are unrelated to the Company's
core business. The boards of directors of the Company and STII have approved an
agreement and plan of merger, subject to conditions including approval by STII's
stockholders, whereby the Company will acquire all of the outstanding shares of
common stock of STII in a tax-free, stock-for-stock exchange. Under the
agreement STII stockholders will receive for each share of common stock US$30 in
the Company stock plus a contingent value right (CVR) which will give them a
participation in the proceeds on the sale of other operations above a minimum
amount. This participation will also be payable in the form of the Company
common shares. The CVR is expected to have a value of up to US$5 per share.

Year 2000 Date Compliance

The Company acknowledges the Year 2000 transition as a serious business issue
and is committed to addressing the challenge of becoming Year 2000 date
compliant. The Company's program ("Year 2000 Date Compliance"), established in
May 1997, addresses compliance both externally, to our customers, suppliers, and
other associates, and internally for the Company's systems and procedures. The
program continues to receive sponsorship and support from the highest levels of
the Company's Management and regular progress meetings are conducted, including
formal quarterly reports to a senior management committee. Despite the extensive
efforts dedicated to the program, there can be no assurance that all Year 2000
Date Compliance activities will be completed before problems associated with the
Year 2000 transition potentially occur.

Various formal messages for conveying Year 2000 Date Compliance information to
customers and other external parties have been developed for Company products.

 .  Year 2000 Date Compliance Statement to Customers and Definition of Terms,
   which indicates how the Company interprets Year 2000 Date Compliance;

 .  The Year 2000 Date Compliance Requirements Specification, which sets forth
   evaluation of products for Year 2000 Date Compliance;

 .  Year 2000 Date Compliance Product List, which lists the Year 2000 Date
   Compliance characterization for the majority of the Company's products and
   releases, including many "discontinued" product offerings.

                                    Page 38
<PAGE>

The Company has completed the evaluation of its major product offerings. The
majority of products have been classified as either Compliant, having Compliant
versions currently available or are Date Compliance Not Applicable. The majority
of older or "discontinued" product offerings have been reviewed, with certain
offerings found to be Non-Compliant, and others that will not be evaluated for
Year 2000 Date Compliance. All the formal messages and Year 2000 Date Compliance
Additional Notes are available on the Company's worldwide web site at
http://www.newbridge.com/year2000/.

The Company recognizes that customers view the Year 2000 rollover as a sensitive
time for their networks and are looking for reassurance that their organizations
will continue to receive service support during this time. It is the Company's
intent to fulfill our contractual obligations to customers during this period.
Throughout the Year 2000 and the following leap year rollovers the three
regional Newbridge Technical Assistance Centers will be operating under the
normal practice of 24 hour, 365 days a year service coverage, including
readiness to address Year 2000 issues. The Company will also ensure staffing
during the rollover period of its Strategic Network Services and Network Design
groups during the rollover period as a component of the Year 2000 Date
Compliance Contingency Planning process. The Company is investigating the
various means by which technical information is disseminated to customers to
ensure the most effective delivery of Year 2000 bulletins during the transition
period. Formal messages from the Company's service organizations to customers
and other external parties are available on the Company's worldwide web site at
http://www.newbridge.com/year2000/.

The internal compliance element of Year 2000 Date Compliance includes the
distribution of responsibility among fourteen "Program Areas" of which each of
the Company's operating groups is represented by at least one. Each group is
responsible for eight main activities that address the exposure of their Program
Areas, as follows.

          i)   Awareness - Inform all employees and ensure awareness of Year
                 2000 Date Compliance issues and how they affect the employees,
                 their customers and their suppliers. This includes ensuring
                 support and dedication to the program throughout the Company.

          ii)  Inventory - Take stock of all information technology (IT) systems
                 and equipment and non-IT systems and equipment in use by the
                 Company potentially affected by Year 2000 Date Compliance.

          iii) Impact Analysis - Assess the significance of each item in the
                 inventory in order to prioritize investigation and testing
                 activities.

          iv)  Investigation and Testing - Examine items recorded during the
                 inventory stage to determine their state of compliance based on
                 the priority set during the impact analysis stage. This step
                 includes requesting product information from suppliers and the
                 formal testing of systems and equipment under controlled
                 conditions.

          v)   Remedial Activities - After analyzing the compliance status of an
                 item, determine remedial action, if any, to be taken should an
                 item be found to be non-compliant. Actions include fixing
                 errors, following a path to make the item compliant, or
                 complete replacement with a compliant alternative.

          vi)  Implementation/Adoption - Once compliance status has been reached
                 the item is made available for use.

                                    Page 39
<PAGE>

          vii) Critical Supplier Assessment - Identify, analyze and assess the
                 Year 2000 readiness of critical suppliers of products and
                 services. Actions include judging assurances that equipment
                 supplied is date compliant, the supplier is also diligently
                 undertaking a Year 2000 readiness plan with respect to its own
                 internal systems to minimize the risk of supply disruptions and
                 that contingency planning activities are active. To assist with
                 and to standardize this task, a formal Year 2000 Date
                 Compliance Supplier Assessment process is being used of which
                 one part is the use of formal readiness questionnaires. The
                 Company's supplier assessment initiatives commenced in April
                 1998 with a mass mailing to over 11,500 vendors from which the
                 Critical Supplier list was originally built. Further targeted
                 mailings and vendor contacts have since been adopted. The
                 Company has not yet obtained adequate assurances from suppliers
                 with respect to their Year 2000 readiness because a significant
                 number (nearly 40% as at end of May, 1999) of questionnaires
                 sent to critical suppliers have not generated a response. The
                 Company will use alternate suppliers in the event that the
                 supplier does not provide satisfactory answers.

          viii)  Contingency Planning - Identify, review and address methods by
                 which the potential of Year 2000 related risks can be further
                 mitigated before they occur. Identify, review and address the
                 criteria for invoking a contingency plan. Identify, review and
                 address the steps which may be necessary to cope with actual
                 operational problems including, as an integral part, increases
                 in service and support resources. To assist with and to
                 standardize this task, a formal Year 2000 Date Compliance
                 Contingency Planning process is being used following a business
                 function review and Year 2000 risk exposure assessment. An
                 essential part of this process is the formulation of Crisis
                 Communications Plans for Year 2000 scenarios.

The Company believes that PC desktop and Unix hardware environments are
substantially compliant. Repeatable automated inventory and remediation
procedures are used to monitor, install and maintain compliance. Adoption of
compliant versions of wide area network equipment is completed and compliance of
office-based local area networks and telephony is proceeding as planned in
accordance with office relocations and infrastructure reinforcement initiatives.
The Company believes that compliance of all business-critical systems has been
substantially completed. To meet changing business requirements the Company
continues to re-evaluate applications that are scheduled for retirement prior to
the Year 2000 rollover and, in some cases, is ensuring their compliance as a
part of ongoing risk mitigation.

The Company's efforts to ensure awareness are on-going throughout the program,
disseminated via the Company's internal web site and through various print
media, which recently included a brochure "The Year 2000 Problem and You"
attached to employee pay stubs.

The costs incurred for Year 2000 Date Compliance are financed internally by the
operating groups within the framework of their operating budgets have not had a
material impact on the Company's financial results (operating expenses as a
percentage of sales, for example). Incremental spending on the Year 2000 Date
Compliance issue is limited to specific program costs which are outside of the
normal course of business and are necessitated purely as a result of Year 2000
date compliance. Incremental spending incurred in fiscal periods reported to
date and projected to be spent in fiscal 2000 associated with the Year 2000
transition represent less than 1% of the Company's revenues and expected
revenues. There can be no assurance that

                                    Page 40
<PAGE>

these costs will not be greater than anticipated, however, as the Company
progresses through its program and greater certainty regarding costs,
particularly related to remediation and contingency plans for identified risks,
will be possible.

The Company is still assessing the potential impact of Year 2000 Date Compliance
on its suppliers and customers and currently cannot fully determine the effect
on its operations and financial condition if key suppliers or customers do not
adequately prepare for Year 2000 Date Compliance transition on a timely basis.
Failure of critical suppliers or customers to address the issue on a timely
basis could result in material financial risk to the Company. As a result, the
Company is actively undertaking Year 2000 Date Compliance contingency planning
as an integral part of the overall program, including service and support
requirements for its customers over the Year 2000 rollover period.

Item 7A.   Quantitative and Qualitative Disclosures About Market Risk

The Company conducts business in several major international currencies through
its worldwide operations. The Company uses financial instruments, principally
forward exchange contracts, in its management of foreign currency exposures. The
Company does not enter into forward exchange contracts for trading purposes. The
Company's management of foreign currency exposures is based upon estimates of
the net asset or net liability position of various currencies, and to the extent
that these estimates are over or understated during periods of currency
volatility, the Company could experience unanticipated currency gains or losses.
Realized and unrealized gains and losses on foreign exchange contracts are
recognized and offset foreign exchange gains and losses on the underlying net
asset or net liability position. The net foreign currency gains and losses, if
any, are recognized in the Consolidated Statements of Earnings as "Other income
(expense)".

The forward exchange contracts primarily require the Company to purchase and
sell certain foreign currencies with or for Canadian dollars at contractual
rates. The table that follows presents a summary of the value of forward
exchange rate contracts outstanding at May 2, 1999 for each currency in which
the Company has hedged a foreign currency exposure. The term of all forward
exchange contracts outstanding at May 2, 1999 was less than one year. The values
shown are the Canadian dollar values of the agreed upon amounts for each foreign
currency that will be delivered to a third party on the agreed upon date.

The unrealized gains or losses on these contracts represent hedges of foreign
exchange gains and losses on the Company's underlying net asset or net liability
position of the various currencies. As a result, Management does not expect
future gains or losses on these contracts to have a material impact on the
Company's financial results.

The Company maintains an investment portfolio consisting of debt securities of
various issuers, types and maturities. The securities that are classified as
held to maturity are recorded on the balance sheet at amortized cost. Due to the
average maturities and conservative nature of the investment portfolio, a sudden
change in interest rates would not have a material effect on the value of the
portfolio.

In January 1998 the Company entered into a Forward Share Price Hedge Agreement
with a major bank in order to fix the value of 545,976 Northern Telecom Limited
(Nortel) shares pledged as security against a term loan.  In January 1999 the
Company amended the Forward Share Price Hedge Agreement in order to fix the
value of a further 108,244 Nortel shares.  The terms of the amended Share Price
Hedge Agreement provide the Company with the option of delivering 654,220 Nortel
shares in January 2003 for proceeds of $51,613,000, or the present value of
$51,613,000, if terminated prior to January 2003, or delivering the cash
equivalent of the market value of 654,220 Nortel shares at January 2003 or at
the date of early termination.

In April 1998 the Company issued US$225,000,000 Senior Notes due April 2003
bearing a coupon rate of 6.51%. Prior to the closing of the Senior Notes the
Company entered into a swap transaction with a major bank under which the
effective coupon rate on US$200,000,000 of the Senior Notes was fixed at 6.678%.

In January 1998 the Company entered into and received $50,000,000 under a loan
agreement which includes a term loan portion and a demand loan portion. The term
loan bears interest at a fixed rate of 5.46% and the demand loan bears interest
at a floating rate equal to one month's bankers acceptance rate. The demand loan
portion of the loan agreement was approximately $15,000,000 at May 2, 1999.

AUDITORS' REPORT



To the Shareholders of Newbridge Networks Corporation:

We have audited the consolidated balance sheets of Newbridge Networks
Corporation as at May 2, 1999 and April 30, 1998 and the consolidated statements
of earnings, shareholders' equity and cash flows for the years ended May 2,
1999, April 30, 1998 and April 30, 1997. These financial statements are the
responsibility of the company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

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

In our opinion, these consolidated financial statements present fairly, in all
material respects, the financial position of the company as at May 2, 1999 and
April 30, 1998 and the results of its operations and the changes in its
financial position for the years ended May 2, 1999, April 30, 1998 and April 30,
1997 in accordance with accounting principles generally accepted in Canada
which, except as disclosed in Note 2, Note 15 and Note 18 to the consolidated
financial statements, also conform in all material respects with accounting
principles generally accepted in the United States.

                NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

                May 2, 1999, April 30, 1998 and April 30, 1997
    (Canadian dollars, tabular amounts in thousands except per share data)


1.   Significant Accounting Policies

The Consolidated Financial Statements have been prepared in accordance with
accounting principles generally accepted in Canada ("Canadian GAAP"). These
principles are also generally accepted in the United States ("U.S. GAAP") in all
material respects except for the disclosure of certain cash equivalents on the
Consolidated Balance Sheets and investing activities on the Consolidated
Statements of Cash Flows, as disclosed in Note 2, the write off of purchased in
process research and development, as disclosed in Note 15, and the method of
calculation of earnings per share, as disclosed in Note 18.

Basis of Consolidation

The Consolidated Financial Statements include the accounts of the Company and
its subsidiaries. Investments in companies in which the Company has significant
influence are accounted for by the equity method. Investments in which the
Company does not control or have significant influence over the investee are
accounted for by the cost method.

Fiscal Year

In fiscal 1998 and years prior the Company's fiscal quarters were 13 weeks long
and closed on a Sunday, except the fourth quarter which closed on April 30.
Commencing in fiscal 1999 the Company adopted the policy of closing its fiscal
years on the Sunday closest to April 30. Accordingly, fiscal 1999 was 52 weeks
long with interim fiscal quarters closing on a Sunday and 13 weeks long.
Occasionally fiscal years will be 53 weeks long, the first occurrence of which
will be for the fiscal year ending May 2, 2004.

Revenue Recognition and Warranties

Revenue from product sales is generally recorded on shipment provided that no
significant obligations remain, with a provision for estimated returns recorded
at that time. In addition, a provision for potential warranty claims is provided
for at the time of sale, based on warranty terms and prior claims experience.
Service revenue is recognized when the service is performed, or, in the case of
maintenance contracts, is recognized as costs are incurred to secure and fulfill
the contract.

Government Incentives and Investment Tax Credits

Government incentives and investment tax credits are recorded as a reduction of
the expense or the cost of the asset acquired to which the incentive applies.
The benefits are recognized when the Company has complied with the terms and
conditions of the approved grant program or the applicable tax legislation.

<PAGE>

Software Development Costs

Certain applications and systems software development costs are capitalized once
technical feasibility has been established for the product, the Company has
identified a market for the product and intends to market the developed product.
No other development costs are capitalized. Such capitalized costs are amortized
over the expected life of the related product.

Inventories

Finished goods are valued at the lower of cost (first in, first out) and net
realizable value. Work in process and raw materials are valued at the lower of
cost and replacement cost.

Property, Plant and Equipment

Property, plant and equipment are stated at cost. Buildings and equipment are
generally amortized on a declining balance basis at rates calculated to amortize
the cost of the assets over their estimated useful lives. Leasehold improvements
are amortized using a straight line basis over the term of the lease.

Goodwill

Goodwill is stated at the difference between the Company's cost of the
investments less its proportionate share of the fair value of the net assets of
the subsidiaries. Goodwill is amortized on a straight line basis over the
estimated useful life of the goodwill, generally between ten and twenty years.
The recoverability of such costs is reviewed on an ongoing basis.

Foreign Currency Translation

The Consolidated Financial Statements are prepared using Canadian dollars. All
operations whose principal economic activities are undertaken in currencies
other than Canadian dollars have been determined to be self-sustaining.

The assets and liabilities of non-Canadian operations are translated at fiscal
year end exchange rates and the resulting unrealized exchange gains or losses
are accumulated as a separate component of shareholders' equity described in the
Consolidated Balance Sheets as "Accumulated foreign currency translation
adjustment". The statements of earnings of such operations are translated at
exchange rates prevailing during the fiscal year.

Other monetary assets and liabilities, which are denominated in currencies
foreign to the local currency of any one operation, are translated to the local
currency at fiscal year end exchange rates, and transactions included in
earnings are translated at rates prevailing during the fiscal year. Exchange
gains and losses resulting from the translation of these amounts are included in
the Consolidated Statements of Earnings.

Use of Accounting Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires Management to make estimates that affect the
reported amounts of assets

<PAGE>

and liabilities and disclosure of contingent assets and liabilities as at the
date of the Consolidated Financial Statements and the reported amounts of sales
and expenses during the reporting periods presented. Actual results could differ
from the estimates made by Management.

Recent Accounting Pronouncements

In June 1997, the Financial Accounting Standards Board ("FASB") issued SFAS 130,
"Reporting Comprehensive Income". SFAS 130 establishes standards for reporting
comprehensive income and its components in the financial statements. The Company
has adopted SFAS 130.

In June 1998, FASB issued SFAS 133, "Accounting for Derivative Instruments and
Hedging Activities". SFAS 133 requires all derivatives to be recorded on the
balance sheet at fair value. SFAS 133 is effective for fiscal years beginning
after June 15, 2000. The Company is in the process of evaluating the impact of
the reporting requirements of SFAS 133.

CICA Handbook - Accounting Section 1540, Cash Flow Statements, which replaces
existing Section 1540 Statement of Changes in Financial Position was issued in
June 1998 and is effective for fiscal years beginning after July 31, 1998. The
impact of this standard will be the disclosure of purchases, maturities and
sales of marketable securities as an investing activity on the Statement of Cash
Flows, in a manner consistent with U.S. GAAP, as is described in Note 2 to these
financial statements. Under this new standard, investing and financing
activities that do not require the use of cash or cash equivalents will be
excluded from the Statement of Cash Flows. However, these activities will be
disclosed elsewhere in the consolidated financial statements. The Company will
adopt this standard in the first quarter of fiscal 2000.

Held to maturity marketable securities are investments with original maturities
of three months or more. Available for sale securities are common shares of
publicly traded companies, which have certain resale restrictions, principally
acquired upon the Company's disposition of its

minority interest in Broadband Networks Inc. Under U.S. GAAP held to maturity
and available for sale marketable securities would be disclosed as a separate
caption on the Consolidated Balance Sheets.

Held to maturity marketable securities are carried at amortized cost. The
unrealized gains and losses are not included in the Consolidated Statements of
Earnings as these gains and losses are unlikely to be realized due to the
Company's intent to hold the underlying securities to maturity. During fiscal
1999 there were no realized gains or losses and unrealized gains of

$70,000 and unrealized losses of $62,000 on held to maturity securities. During
fiscal 1998 there were no realized or unrealized gains or losses on held to
maturity securities. Available for sale securities are carried at the lower of
cost and market. During fiscal 1999 the Company incurred $707,000 of realized
losses and in fiscal 1998 the Company realized gains of $573,000 from available
for sale securities.

purchases, maturities and sales of marketable securities would be disclosed as
an investing activity.

10.  Financial Instruments and Concentration of Credit Risk

The Company uses financial instruments, principally forward exchange contracts,
in its management of foreign currency exposures. Realized and unrealized gains
and losses on foreign exchange contracts are recognized and offset foreign
exchange gains and losses on the underlying net asset or net liability position.
These contracts primarily require the Company to purchase and sell certain
foreign currencies with or for Canadian dollars at contractual rates. At May 2,
1999 the Company had $363,028,000 in outstanding foreign exchange contracts
(April 30, 1998 - $170,084,000).

In January 1998 the Company entered into a Forward Share Price Hedge Agreement
with a major bank in order to fix the value of the Nortel shares pledged as
security against a term loan (see Note 9). In January 1999 the Company amended
the Forward Share Price Hedge Agreement in order to fix the value of a further
108,244 Nortel shares. The terms of the amended Forward Share Price Hedge
Agreement provide the Company with the option of delivering 654,220 Nortel
shares in January 2003 for proceeds of $51,613,000 or the present value of
$51,613,000 if terminated prior to January 2003, or delivering the cash
equivalent of the market value of 654,220 Nortel shares at January 2003 or at
the date of early termination.

Several major financial institutions are counterparties to the Company's
financial instruments. It is Company practice to monitor the financial standing
of the counterparties and limit the amount of exposure to any one institution.
The Company may be exposed to a credit loss in the event of nonperformance by
the counterparties to these contracts, but does not anticipate such
nonperformance.

    (Canadian dollars, tabular amounts in thousands except per share data)

With respect to accounts receivable, concentration of credit risk is limited due
to the diverse areas covered by the Company's operations. The Company has credit
evaluation, approval and monitoring processes intended to mitigate potential
credit risks. Anticipated bad debt loss and product returns have been provided
for in the allowance for returns and doubtful accounts. Net additions to the
provision for returns and doubtful accounts (fiscal 1999 -- $3,150,000; fiscal
1998 -- $2,495,000) primarily relate to estimates for products to be returned
and have been charged to sales. The carrying amounts for cash, marketable
securities, accounts receivable, accounts payable and accrued liabilities
approximate fair value because of the short maturity of these instruments.

11.  Share Capital

Authorized

An unlimited number of Common Shares.

An unlimited number of participating preferred shares, ranking in priority upon
distribution of assets over Common Shares, may be issued in series with
additional provisions as fixed by the Board of Directors.

Employee Stock Option Plans

The Company has established the Newbridge Networks Corporation Consolidated Key
Employee Stock Option Plan (the "Plan") applicable to full-time employees,
directors and consultants of the Company and its subsidiaries. The options under
the Plan are granted at the then-current fair market value of the Common Shares
of the Company and generally may be exercised in equal proportions during the
years following the first, second, third and fourth anniversary of the date of
grant, and expire on the fifth anniversary or upon termination of employment.
Options granted under the Plan prior to August 1, 1996 generally may be
exercised in equal proportions during the years following the first, second and
third anniversary of the date of grant, and expire on the fourth anniversary or
upon termination of employment. In addition to the number of options outstanding
as at May 2, 1999, the aggregate number of options which may be granted under
the Plan was 6,624,514.

Stock Based Compensation

The Company applies APB 25 and related interpretations in accounting for its
Consolidated Key Employee Stock Option Plan. Accordingly, no compensation
expense has been recognized for its stock based compensation plan. Had
compensation costs for the Company's Consolidated Key Employee Stock Option Plan
been determined based on the fair value at the grant date for awards under the
Plan, consistent with the methodology prescribed under SFAS 123, the Company's
net earnings (loss) and earnings (loss) per share would have been decreased to
the following pro forma amounts.

The Black-Scholes model used by the Company to calculate option values, as well
as other currently accepted option valuation models, were developed to estimate
the fair value of freely tradable, fully transferable options without vesting
restrictions, which significantly differ from the Company's stock option awards.
These models also require highly subjective assumptions, including future stock
price volatility and expected time until exercise, which greatly affect the
calculated values. Accordingly, Management believes that this model does not
necessarily provide a reliable single measure of the fair value of the Company's
stock option awards.

Employee Share Purchase Plan

The Company's Employee Stock Purchase Plan ("ESPP"), was effective June 1, 1999
and allows eligible employees to authorize payroll deductions up to 10% of their
salary to purchase Common Shares of the Company at a price of 85% of the then
current stock price (as defined in the ESPP). Employees purchasing shares under
the ESPP must hold the shares for a minimum of one year. The Company has
reserved 500,000 Common Shares for issuance under the ESPP.

12.  Comprehensive Income

The Company has adopted the United States Financial Accounting Standards Board
Statement of Financial Accounting Standards No. 130, Reporting Comprehensive
Income. This statement requires disclosure of Comprehensive Income, which
includes reported net earnings adjusted for other comprehensive income. Other
comprehensive income includes items that cause changes in shareholders' equity
but are not related to share capital or net earnings which, for the Company,
comprises only the foreign currency translation adjustment.

13.  Research and Development

During the year, the Company recorded Canadian Investment Tax Credits of
$37,846,000 (fiscal 1998 -- $34,971,000; fiscal 1997 -- $26,400,000) as a
reduction of research and development expenses.

The Company recorded government and customer funding during the year of
$29,234,000 (fiscal 1998 -- $5,507,000; fiscal 1997 -- $9,484,000) as a
reduction in research and development expenses included in the consolidated
statements of earnings. Funding from the government of the province of British
Columbia amounted to $10,000,000 during the year and is contingently repayable
over a period not to exceed ten years. Repayment of the funding is based on a
percentage of sales of products developed in British Columbia and a percentage
of sales of products sold in British Columbia. Any funding not repaid at the end
of the ten year period would be forgiven. The Company also recorded funding of
$17,540,000 during the year related to eligible research and development
expenditures of its broadband wireless program. Royalties are due to the funding
companies based on a percentage of sales of products developed under the
program. The funding companies own the intellectual property rights for products
developed under the program. The Company has an option to acquire those rights
under certain terms and conditions. As part of the arrangements, Newbridge has
provided

In April 1999, the Company decided to streamline the operations of regional
sales and support organizations as well as its marketing and product development
organizations. The restructuring costs associated with the sales, support and
marketing organizations ("Sales and Marketing") consisted primarily of costs
related to workforce and facilities reductions, as the Company has announced a
reduction in the number of locations in which it will have a physical presence
in favour of distributors in certain markets, and subcontractors for certain
functions. Restructuring costs associated with product development relate
primarily to asset impairment losses related to the capping, discontinuation or
divestiture of the development of certain products, and the centralization of
development laboratories to make the development process more efficient.
Restructuring costs of $73,570,000 comprised the following:

The provision for the reduction in work force includes severance, related
medical and other benefits, and other obligations to employees. The provision
includes termination benefits for approximately 200 employees. The work force
reductions will occur in Japan, Russia and various other countries. The Company
anticipates that these work force reductions will be substantially completed in
the first half of fiscal 2000.

The provision for the reduction in facilities comprises primarily lease payments
and fixed costs associated with the closure of sales, support and administrative
facilities in Europe, Japan and the United States. The Company expects to
complete these facilities closures in the first half of fiscal 2000.

The provision for other restructuring costs comprises professional fees and
other various direct incremental costs associated with the restructuring plan.

In October 1998, the Company decided to discontinue the sale and development of
local area network (LAN) Layer 2 Switching products as part of the enhancement
of the focus on the Company's dominant and more profitable products. This
program, which was completed during the fiscal 1999, created impairment losses
of $30,690,000 associated with certain assets deployed in this business and
obligations related to fulfilling previous customer commitments of $7,238,000,
all of which was incurred prior to the end of fiscal 1999.

In October 1998, the Company commenced relocating certain employees and
activities that support the Asia Pacific region from Kanata, Ontario to Hong
Kong and Malaysia in order to provide more efficient and cost effective services
to customers in that region. The charge of $6,532,000 incurred in October 1998
reflects the accrual of involuntary termination benefits, lease cancellation
penalties and other direct costs associated with the transition. As at May 2,
1999, $1,215,000 of these costs had been incurred. Additional costs related to
the transfer of personnel and equipment, the recruitment of new staff and the
expansion of facilities in Hong Kong are not included in the Asia Pacific
Resources Relocation charge and are being expensed as incurred. These additional
costs are estimated at $9,000,000, with the majority of the costs to be incurred
during the first two quarters of fiscal 2000.

In November 1997, the Company restructured its activities relating to its LAN
business.  The restructuring plan involved the formation of an alliance with a
company strongly positioned in the LAN business, and the reduction of the
Company's direct participation, and related costs, in the LAN business. In
repositioning the way in which the Company addressed the LAN market, the
restructuring plan created impairment losses on certain assets associated with
the LAN business and liabilities associated with restructuring activities.
Accordingly, the Company recognized restructuring costs of $181,444,000 in the
third quarter of fiscal 1998. The provision recorded for this restructuring plan
in November 1997, predominantly related to reductions in the Company's
workforce, was $39,638,000. During fiscal 1998, $34,345,000 of these
expenditures were incurred with the remaining $5,293,000 incurred in fiscal
1999. The restructuring plan has been completed.

15.  Purchased Research and Development In Process

In November 1997, the Company acquired a 49.9% equity interest in RadNet Ltd.,
an Israeli developer and manufacturer of access switches for ATM networks, for
cash consideration of $53,676,000. The majority of the purchase price
($52,762,000) was allocated to purchased research and development in process.
The amount allocated to purchased research and development in process was
determined through valuation techniques common in the high technology industry.
Under accounting principles generally accepted in Canada, the purchased research
and development in process was amortized on a straight line basis over its
estimated useful life of six months. Under U.S. GAAP, purchased research and
development in process acquired by the Company was written off at the time of
acquisition.

In December 1998, the Company sold its minority ownership position in Cambrian
Systems Corporation ("Cambrian") to Nortel for cash proceeds of US$95,674,000
(Cdn$147,158,000). The proceeds include an earn-out payment of US$1,935,000
(Cdn$2,855,000) received by the Company as a result of certain specified
financial performance targets being met by Cambrian. The proceeds exclude future
potential earn-out payments of approximately US$21,000,000 which will be
received by the Company if certain specified financial performance targets are
met by Cambrian.

In October 1998, the Company completed the sale of its majority ownership
position in Advanced Computer Communications ("ACC") to Telefonaktiebolaget LM
Ericsson for cash proceeds of US$167,319,000 (Cdn$258,308,000). ACC's results of
operations were consolidated with the Company's results for the first six months
of fiscal 1999 ended November 1, 1998. The results of operations and the
financial position of ACC were not significant relative to the Company's
consolidated results of operations and financial position for all periods
presented.

In December 1998, the Company sold its minority ownership position in Vienna
Systems Corporation to Nokia Corporation for cash proceeds of $39,716,000.

In February 1999, the Company sold a portion of its minority ownership position
in Tundra Semiconductor Corporation for cash proceeds of $19,498,000 as part of
an initial and secondary share offering by Tundra.

In January 1998, the Company sold its minority interest in Broadband Networks
Inc. to Nortel for proceeds of $66,672,000.  The proceeds received included cash
of $23,775,000 and Nortel shares valued at $42,897,000.

On February 10, 1999 West End Systems Corp., a manufacturer of access and
transmission products for the communications and cable television industries,
filed an assignment in bankruptcy under the Canadian Bankruptcy and Insolvency
Act.  As a result, the Company recorded losses related to its minority ownership
position in West End Systems Corp. and unsecured trade accounts outstanding.

The Company evaluates, on an ongoing basis, the value of its long term
investments considering the evolution of the market segments of investee
companies, any impact of deteriorating economic conditions in various countries,
and any other specific information which indicates impairment of value of these
investments. In fiscal 1999, the financial performance of certain investee
companies as well as deteriorating economic conditions in Brazil and Russia led
to investment impairment write downs of $65,431,000.

The Company recorded a future tax benefit for net operating loss carryovers
associated with certain acquisitions. These losses will expire at various dates
through the year 2012. The components of the future tax benefit (obligation)
classified by the source of timing difference that gave rise to the credit are
not materially different from the temporary differences as calculated under the
application of U.S. GAAP.

At May 2, 1999, the Company had available investment tax credits of
approximately $53,106,000 for the reduction of future years' Canadian federal
income tax liability. These credits, which are subject to customary review
procedures by Revenue Canada, expire during the years 2007 to 2009. Of this
amount $10,913,000 has been applied to reduce the future tax obligation. No
recognition has been given in these financial statements to the potential tax
benefits associated with the remaining balance of investment tax credits. Under
U.S. GAAP the remaining balance of investment tax credits would be disclosed,
offset by a valuation allowance.

18.  Earnings (Loss) per Share

Basic earnings (loss) per share has been calculated on the basis of net earnings
(loss) for the period divided by the daily weighted average number of Common
Shares outstanding during the fiscal year.

The calculation of fully diluted earnings per share assumes that, if a dilutive
effect is produced, all outstanding options had been exercised at the later of
the beginning of the fiscal period and the option issue date, and includes an
allowance for imputed earnings of $28,943,000 (fiscal 1998 -- $18,521,000;
fiscal 1997 -- $11,589,000) derived from the investment of funds which would
have been received at an after tax rate of 3.5% (fiscal 1998 -- 3.0%; fiscal
1997 -- 3.1%).

Under U.S. GAAP, basic earnings per share has been calculated as net earnings
for the period divided by the daily weighted average number of Common Shares
outstanding during the period, consistent with the calculation of basic earnings
per share under accounting principles generally accepted in Canada. Diluted
earnings per share is calculated using the treasury stock method. Earnings per
share in U.S. dollars is disclosed for the convenience of the reader. The
exchange rates used for translation are based on the average of the daily noon
buying rates for Canadian dollars in U.S. dollars as reported by the Federal
Reserve Bank of New York. The calculation of earnings per share under U.S. GAAP
is as follows.

The Company manages its assets by geographic region, rather than through the
operating segments. Decision making and performance assessment with regard to
assets is done on a geographic basis because the operating segments may share
assets and accountability by operating segment would be less readily
determinable.

21.  Litigation

In the fourth quarter of fiscal 1998 the Company reached an agreement in
principle to settle the class action lawsuit which was filed in United States
District Court in Washington, D.C. during the fiscal year ended April 30, 1995.
The lawsuit purported to be a class action on behalf of a class of persons who
purchased securities of the Company between March 29 and August 1, 1994 and
alleged that the Company made false and misleading statements in violation of
United States securities law and common law. The Court entered an order and
final judgement approving the settlement and dismissing the lawsuit with
prejudice in October 1998. The Company recorded the expense in connection with
the settlement of $2,642,000 in the fourth quarter of fiscal 1998, which
represents the direct costs incurred.

Lucent Technologies Inc. ("Lucent Technologies") filed a complaint during the
fiscal year ended April 30, 1998 in United States District Court in Delaware
against the Company and its United States subsidiary, Newbridge Networks Inc.
Lucent Technologies manufactures and sells telecommunications systems, software
and products, and is both a distributor of the Company's products and a
competitor of the Company. The Complaint alleges that the Company's manufacture
and sale, in the United States, of some of the standardized functions on the
Newbridge frame relay and ATM switch products, along with its ADPCM (adaptive

differential pulse code modulation) and card initialization implementations,
infringe certain United States patent rights claimed by Lucent Technologies.
The Complaint requests actual and trebled damages in an unspecified amount.
Based upon its present understanding of the laws in the United States and the
facts, the Company believes it has meritorious defenses to these claims. The
Company has filed an answer to the Complaint and is defending this action
vigorously. Because the outcome of the action is not certain at this time, no
provision for any liability that may result upon adjudication has been made in
these Consolidated Financial Statements.


22. Uncertainty Due to the Year 2000 Issue

The Year 2000 Issue arises because many computerized systems use two digits
rather than four to identify a year. Date-sensitive systems may recognize the
year 2000 as 1900 or some other date, resulting in errors when information that
uses year 2000 dates is processed. In addition, similar problems may arise in
some systems that use certain dates in 1999 to represent something other than a
date. The effects of the Year 2000 Issue may be experienced before, on, or after
January 1, 2000, and, if not addressed, the impact on operations and financial
reporting may range from minor errors to significant systems failure that could
affect an entity's ability to conduct normal business operations. It is not
possible to be certain that all aspects of the Year 2000 Issue affecting the
entity, including those related to the efforts of customers, suppliers, or other
third parties, will be fully resolved.

23. Subsequent Events

In May 1999, the Company completed its investment in TeraBridge Technologies
Corporation ("Terabridge"), which specializes in delivering intelligent call and
service control products to service providers and is headquartered in Gurnee,
Illinois. The Company acquired a 19% equity ownership position for US$60,000,000
(Cdn$90,511,000) and has an option to increase its equity ownership position to
50% for US$10,000,000.

In June 1999, the Company announced a definitive agreement to acquire Stanford
Telecommunications Inc. ("STII") (STII: NASDAQ), a leading supplier of broadband
wireless technology and products. The net purchase price of the acquisition is
estimated at US$280,000,000 (Cdn$ 411,740,000) which represents the gross
purchase price of approximately US$490,000,000 (Cdn$720,545,000) net of proceeds
from the divestiture of divisions of STII that are unrelated to the Company's
core business. The boards of directors of the Company and STII have approved an
agreement and plan of merger, subject to conditions including approval by STII's
stockholders, whereby the Company will acquire all of the outstanding shares of
common stock of STII in a tax-free, stock-for-stock exchange. Under the
agreement STII stockholders will receive for each share of common stock US$30 in
the Company stock plus a contingent value right (CVR) which will give them a
participation in the proceeds on the sale of other operations above a minimum
amount. This participation will also be payable in the form of the Company
common shares. The CVR is expected to have a value of up to US$5 per share.

    (Canadian dollars, tabular amounts in thousands except per share data)



For the purpose of this transaction, the value of a Newbridge common share shall
equal the ten-day average closing price on the New York Stock Exchange, ending
on the fifth trading day immediately preceding STII's stockholder vote, expected
in October. If the Newbridge stock price, pursuant to this calculation, is below
US$24 and the Company does not exercise its right to adjust the exchange ratio,
STII's board will be permitted to terminate the Agreement.

The quarterly financial data for the fiscal years ended May 2, 1999 and April
30, 1998 are derived from unaudited consolidated financial statements of the
Company which include, in the opinion of Management, all normal and recurring
adjustments considered necessary for a fair statement of results for such
periods. The selected quarterly financial data should be read in conjunction
with "Management's Discussion and Analysis of Financial Condition and Results of
Operations" and the Consolidated Financial Statements and Notes thereto included
