      At May 18,  2000,  114,123,921  common  shares of Mitel  Corporation  were
issued and outstanding. Non-affiliates of the registrant held 100,438,453 shares
having an aggregate market value of U.S.  $1,977,382,043  based upon the closing
price of the common  shares on the New York Stock  Exchange  (May 18, 2000 being
the last trading day) of U.S. $19.6875.

      Common shares held by shareholders holding more than 5% of the outstanding
common shares and by each  executive  officer and director of Mitel  Corporation
have been  excluded  from the  non-affiliated  common  share  total in that such
persons may be deemed to be affiliates of Mitel. Exclusion of such common shares
is not  necessarily a conclusive  determination  of the affiliate  status of any
holder thereof for any other purpose.

      Item 1. Business

      Mitel maintains its financial accounts in Canadian dollars.  All financial
information  and  references  to "$" and  "dollars" are expressed in millions of
Canadian  dollars  unless  otherwise   stated.   Unless  the  context  indicates
otherwise,  "Mitel"  and  the  "Company"  refer  to  Mitel  Corporation  and its
consolidated  subsidiaries.  A glossary of certain  technical and industry terms
used in this Annual Report on Form 10-K is included as Annex A attached.

      Overview

      Mitel  Corporation was  incorporated in Canada in 1971 and continued under
the Canada  Business  Corporations  Act in 1976. The  registered  office and the
principal  executive  offices of Mitel  Corporation are located near the capital
city of Ottawa in Canada, at 350 Legget Drive, Kanata,  Ontario,  Canada K2K 2W7
and its telephone number at that address is (613) 592-2122.

      Mitel is a global designer, manufacturer and marketer of networked systems
and specialty  semiconductors  for the communications  industry.  Mitel operates
through  two  principal  business   segments,   Mitel   Communications   Systems
("Systems") and Mitel Semiconductor ("Semiconductor").

      Since  the  mid-1980s,   the  global  communications   industry  has  been
characterized  by  rapid  structural   change  and  economic  growth  caused  by
technological  innovation,  economic factors, and changes in government policies
that encourage  competition and increase choice.  The evidence for these changes
includes the growing  impact of the  Internet,  optical  networking  technology,
broadband  connectivity,  wireless  and  mobile  communications,  and  demand by
enterprises for cost-effective, multi-functional networks and applications.

      Management believes that the impacts of these factors are intensifying and
that  the   complexity   of  networks   demanded  by  customers   will  increase
significantly over the next several years. In addition, management believes that
network  platforms  will  become  increasingly  multifunctional  and  converged,
supporting  multiple  access to combined  voice,  data and video  communications
services,  thus reducing the operating costs associated with separate  networks.
Management  further  believes  that  in  the  enterprise  market,  traditionally
distinct voice and data  technology  platforms will converge  around an Internet
Protocol-based network.  Management anticipates that significant industry growth
areas will  include  wireless  access,  multifunctional  systems and  networking
software.

      Business Strategy

      Mitel's  strategy is to exploit seven major  developments  that management
believes are under way in the communications industry:

      o     Convergence  of voice and data  transport in the  enterprise  around
            Internet Protocol ("IP").

      o     Emergence of broadband connectivity as a fundamental requirement for
            moving voice, data and image traffic over converging networks.

      o     Growth   of   unprecedented    IP-centric   interactive   multimedia
            applications and services.

      o     The   increasing  use  of  System  Level   Integration   ("SLI")  in
            microelectronics to reduce size,  increase  functionality and reduce
            the cost of networking solutions.

      o     Emergence of customer premise equipment ("CPE") wireless systems for
            seamless indoor-outdoor  mobility.

      o     Simplification  of  non-real-time  modes of  communications  through
            Unified Messaging.

      o     Acceptance of natural  speech  recognition  for call routing and the
            potential to "voice surf" the Internet.

      Mitel's  competencies  range from  microelectronic  components  for wired,
wireless and optical  communications to fully networked  multimedia  systems and
applications  for  enterprise  customers.  In its Systems  business,  management
believes the Company's  products have  competitive  advantages  because of their
real-time  and  fault-tolerant  system  architecture  design,  and the Company's
ability   to   integrate    microelectronic   and   system   designs,    develop
software-intensive  applications,  including call centers and messaging systems,
and the strength of its distribution  channels.  In its Semiconductor  business,
management  believes the Company's  competitive  advantages  include  design and
production   capability   for  SLI  solutions   including   analog  and  digital
mixed-signal ICs; media-transparent connectivity for wired, wireless and optical
applications;  and  engineering  process  diversity for specialty  designs (e.g.
ultra-low power and ultra-low  voltage  integrated  circuits ("ICs") for medical
applications).

      The key elements of Mitel's business strategy include the following:


                                       2
<PAGE>

      o     To evolve its  communications  systems and products from proprietary
            platforms to open,  scalable  and  distributed  architectures  using
            industry  standards (e.g. IP), thereby achieving larger economies of
            scale, additional customer benefits and shorter delivery cycles.

      o     To become a fabless  semiconductor  company for deep  sub-micron SLI
            designs,  while continuing to own and operate fabrication facilities
            specializing in Complementary Metal Oxide Semiconductor ("CMOS") and
            bipolar  technologies  for  strategic  advantage  in such  areas  as
            mixed-signal, high-frequency and medical applications.

      o     To leverage its semiconductor and systems  technology to benefit all
            of the Company's  customers,  from the  manufacturers who buy highly
            integrated   microelectronics   to  end  users  who  purchase  fully
            functional systems.

      In the Systems  business unit,  Mitel will continue to focus on leadership
in modular,  fiber-optic-based  voice  communications  systems for the under-400
line size in the small/medium enterprise segment, and in networking technologies
that enable Mitel to scale its systems to larger line sizes. Mitel will continue
to develop voice products as an application  within the  information  technology
("IT")  infrastructure.  Mitel  will  also  seek to  capitalize  on its  systems
integration skills to market complete,  fully featured communications systems to
selected vertical  markets,  principally the hospitality,  educational,  health,
professional and financial services markets. See "Business-Mitel  Communications
Systems-Products and Customers."

      Management  believes  the  Company is well  positioned  to  implement  its
business strategy in Semiconductor by reason of its strong core technologies for
signaling, transporting and switching voice and data; and its strong position in
RF  technology  with  applications  ranging  from  tuners for  set-top  boxes to
cellular telephones. Its unique ultra-low-power CMOS process enables the Company
to maintain a major position in medical  applications,  while paving the way for
other low-power SLI solutions.  The Company also has expertise in optoelectronic
devices  principally found in transmitters and receivers for Local Area Networks
("LANs") and access networks.  See  "Business-Mitel  Semiconductor-Products  and
Customers."

      Recent Events

      Acquisition

      On June 6, 2000,  the Company  entered  into an  agreement  to acquire 100
percent of the common  stock of  privately-held  Vertex  Networks,  Incorporated
("Vertex"), for total consideration of 11 million common shares issued by Mitel.
The  acquisition  will be  accounted  for by the purchase  method with  Vertex's
results from  operations  included in the  consolidated  accounts of the Company
from the date of  acquisition,  expected to be on or before August 30, 2000. The
fair  value of the  consideration  will be  determined  by the fair value of the
Company's common shares, as adjusted where appropriate,  near the effective date
of acquisition.

      Vertex  is a  fabless  semiconductor  company  providing  high-performance
network  packet  processing,  switching  and routing  silicon  solutions for the
enterprise  and wide  area  network  ("WAN")  access  markets.  Vertex  provides
integrated  circuits for Layer 3 IP routing  switches and  developing  chipsets,
reference designs,  and software for intelligent packet switching  applications.
Vertex's products encompass Quality of Service  ("QoS")-enabled IP switching for
enterprise  communications,  WAN  traffic  concentration,  and fiber to the home
("FTTH")  markets.  Vertex,  which  was  founded  in 1995,  is based in  Irvine,
California,  United States, and has design centers in San Jose, California,  and
Taiwan.  The Company intends to continue  operating these design centers for the
same purposes as prior to the  acquisition.  Vertex  employed  approximately  75
people as at May 31, 2000.


                                       3
<PAGE>

      Management  believes the  acquisition  of Vertex will allow Mitel to enter
the packet processing and switch fabric market to offer  system-wide,  IP-based,
QoS for convergent  networks.  QoS is a term that qualifies certain  performance
attributes  of voice  transmission  over IP  networks,  and  usually  refers  to
measures of delay,  latency and jitter.  Mitel's  focus will be to deliver  wire
speed  non-blocking  scalability  for the edge of WANs,  providing  the  maximum
packet-switching  throughput  required by systems designers and their customers.
The approach will introduce LAN cost structures into WAN applications to provide
a more competitive solution that accommodates diverse switching  technologies in
use at the edge of the network.

      Divestiture

      On March 26, 1999, the Company adopted formal plans to pursue  divestiture
opportunities  related  to the  distinct  operations  of the  Lincoln  Power and
Automotive   business  segment   ("Lincoln")  which  was  part  of  the  Plessey
Semiconductors Group acquired in Fiscal 1998. The formal plan to dispose of this
segment was part of the  Company's  efforts to focus on its core  communications
business.  Accordingly,  the operations  related to this business were accounted
for as discontinued  operations.  On January 19, 2000, the Company completed the
sale of Lincoln for total  consideration  of $12.0. As a result of the sale, the
Company recorded  additional  provisions of $8.0, net of tax recoveries of $3.4,
as a loss from discontinued operations in the third quarter of Fiscal 2000.

      Common Share Repurchase Program

      On June 7,  1999,  the  Company  announced  its  Board  of  Directors  had
authorized a normal  course  issuer bid to  repurchase  up to  5,835,645  common
shares (5% of 116,712,906  common shares issued and outstanding at May 28, 1999)
between June 9, 1999 and June 8, 2000. All repurchased shares were cancelled. As
at May 18,  2000,  3,383,800  shares were  purchased  and  cancelled  under this
program for cash consideration of $36.4, including costs to acquire the shares.

      On June 5,  2000,  the  Company  announced  its  Board  of  Directors  had
authorized  the  continuation  of  its  normal  course  issuer  bid  program  to
repurchase up to 5,706,196 common shares,  representing 5% of 114,123,921 common
shares issued and  outstanding at May 18, 2000. The purchases will take place on
the open market  through  the stock  exchanges  of New York and  Toronto  over a
twelve-month  period beginning on June 9, 2000 and ending on June 8, 2001, or on
such  earlier date as the Company may  complete  its  purchases  pursuant to the
notice of  intention to make a normal  course  issuer bid filed with The Toronto
Stock Exchange.  The Company,  which intends to cancel the  repurchased  shares,
believes that at present no director,  senior  officer or insider of the Company
intends to sell any common shares under this program.

      Executive Appointments

      During Fiscal 2000, Mitel made a series of executive appointments designed
to bolster the strength of Mitel's  management  team.  With annual sales of $1.4
billion,  the Company is augmenting  its management  and  professional  ranks to
reflect  its new  competitive  standing as a global  supplier of  communications
products in a networked  world.  Of note,  the following  significant  executive

            and strategic marketing.

      MITEL COMMUNICATIONS SYSTEMS

      Industry

      Mitel  is  positioning  itself  for  rapid  growth  in its  communications
business.  Management  believes  that voice  networks will undergo a significant
transformation  in  the  near  future,  and  that  this  transformation   offers
significant growth opportunity for Mitel Communication Systems ("MCS").

      To date,  PBXs have been built with  proprietary  hardware  and  software,
using TDM protocol. In the future,  management expects that open-system hardware
and software using IP will replace these platforms.  At the same time, the voice
network will  converge with the data network - and the video  network.  In other
words, enterprises will migrate to an "all-in-one" communications network, which
delivers multiple media types on a single network.

      This transformation offers two significant growth opportunities for Mitel.
The first opportunity is VoIP ("Voice over IP").  Enterprises will replace their
existing  proprietary PBX platforms with open standards based "IPBX"  ("Internet
Protocol Branch Exchanges") platforms. Management believes that enterprises will
make  significant  investments  on this  conversion,  and  MCS,  as an  industry
proponent in open  standard  "IPBXs",  is


                                       5
<PAGE>

well  positioned to capitalize on this  convergence  opportunity.  MCS will also
benefit from the demand for new IP based telephone  sets,  which are designed to
take advantage of the new converged enterprise infrastructure.

      The second opportunity is voice applications. Management believes that, in
an IP-based,  open standards world, the most significant "value-add" will reside
in   applications.   Management   expects   significant   growth  in  all  voice
applications, including:

      o     Natural speech applications that allow words and phrases spoken over
            the  telephone  to  serve  as  commands  to  perform  a  variety  of
            sophisticated   tasks,  such  as  message  browsing,   dialing,  and
            web-browsing;

      o     Wireless  office  systems  that provide  full PBX  functionality  on
            standard wireless handsets;

      o     Unified  messaging that  integrates  voicemail,  email and fax mail,
            allowing mobile users one point of contact for their messages;

      o     Enhanced  Automatic Call Distribution  ("ACD") and Interactive Voice
            Response ("IVR"), especially for the growing call center market;

      o     CTI which  allows the  linking  of voice and data  systems to permit
            data and control information to be transferred between systems, thus
            providing integrated applications; and

      o     Applications   specific   to  the  needs  of   particular   vertical
            industries, to help enterprises resolve their business issues.

      MCS is  aggressively  exploring  opportunities  in the  above  application
areas.  Together  with the market for VoIP,  these market  trends will offer MCS
higher  growth  opportunities  than those in the  traditional  PBX industry over
recent years. Moreover,  coming from a historical strength in voice,  management
believes  MCS is uniquely  positioned  to succeed in the new world of  converged
communications,  where voice is a key medium for  messaging  and data access- in
addition to being the preferred medium for real-time communication.

      Products and Customers

      Systems  revenue  grew by 5% in Fiscal  2000 and by 33% in Fiscal 1999 and
accounted for 57%,  57%, and 64% of the Company's  total revenue in Fiscal 2000,
1999, and 1998, respectively.  As discussed in the preceding section, management
is positioning  itself for higher growth,  by focusing on  opportunities in VoIP
and in applications.

      Currently  MCS  products  are  primarily  premise-based  systems  used  by
enterprises to communicate within and between locations, supporting the needs of
branch offices,  mobile workers,  and  teleworkers.  Management will continue to
focus on this business, both in its biggest markets (the U.S. and the U.K.), and
in other markets (e.g. mainland Europe, emerging markets). At the same time, the
Company intends to grow its applications  business in addition to its businesses
in network access solutions and public switching products.

      Enterprise Communications Systems

      Time Division Multiplex ("TDM") Systems

      Mitel's enterprise communications systems, including TDM-based PBX systems
located  on the  customer's  premises,  permit a number of local  telephones  or
computer  terminals to communicate  with each other,  with or without use of the
public  telephone  network.  Mitel's PBX products  are divided  into  categories
adapted to the particular business size, configuration and need of the end user.
Over the past 20 years,  Mitel's PBX products have evolved from analog  products
to the current family of digital  products.  The Company's current line of LIGHT
products  and related  peripherals  permit the  communication  of voice and data
information


                                       6
<PAGE>

over conventional  twisted-pair telephone wires or optical fiber. Mitel's larger
products provide networking capabilities to link up to hundreds of locations.


                                       7
<PAGE>

      Although  Mitel no longer  manufactures  new  analog  PBX  equipment,  the
Company  continues  to support its  existing  analog PBXs by offering a complete
line of  remanufactured  equipment that performs to specifications at the latest
revision level.

      Mitel's family of SX-2000 products utilizes digital  switching  technology
to  provide  advanced  voice  and data  capabilities  for  businesses  requiring
flexibility  to configure a system that meets  specific user needs.  The SX-2000
and its networking protocols bring  fully-integrated voice and data capabilities
to the desktop over single  twisted-pair  wiring. To support networks  utilizing
these  products,  Mitel  offers OPS  Manager,  an  off-board  computer  software
application  that is closely  integrated  with the  SX-2000  to perform  network
management from a central location. To maximize tariff efficiencies, the SX-2000
offers  advanced  features to support  Automatic  Route Selection and Least Cost
Routing.  In Fiscal 2000, Mitel  introduced  Lightware 30, the latest release of
its advanced  call  control  software.  Lightware  30 software  doubles the port
capacity  of the  SX-2000;  increases  voicemail,  network  management  and  911
functionality; and offers PBX vendor interoperability.

         The SX-200 line of digital  products  provides small- and  medium-sized
customers in North America with the advanced  telephone features found in larger
systems  such as the  SX-2000.  Products in the SX-200 line  interface to a wide
variety  of user  peripheral  devices.  In Fiscal  1997,  Mitel  introduced  the
SX200ML,  a smaller but fully functional  SX-200 aimed at the 40 to 60 line-size
business market.  In Fiscal 1998, Mitel introduced the next generation SX-200 EL
for the 50 to 250 line-size business market.

      In Fiscal 2000, Mitel introduced two new warranty  programs:  the Extended
Hardware  Warranty  Program and the IP Investment  Protection Plan. The Extended
Hardware  Warranty  Program  extends the hardware  warranty on Mitel's family of
SX-200 and  SX-2000  PBXs from one to five  years,  significantly  reducing  the
lifecycle  costs of a customer's PBX  investment.  The IP Investment  Protection
Plan ensures that the call control functionality of Mitel's core product family,
the SX-200  LIGHT and the  SX-2000  LIGHT  PBXs,  as well as  peripheral  nodes,
circuit cards,  telephone  sets and voice mail, can be re-used and  re-connected
from the legacy PBXs to Mitel IP-based PBXs.

      Mitel offers a suite of ISDN  business  products,  led by the  iMAGINATION
line, to the small- to-medium enterprise market in Europe. The iMAGINATION range
has been enhanced by the addition of Mitel Kontact, a router and an Ethernet hub
that is an  all-in-one  solution  for small  businesses.  The Kontact  product's
inherent   capabilities  for  credit  card  authorization  and  electronic  data
interchange ("EDI") are well suited for the retail market.


      All of  Mitel's  PBX  systems  can be  configured  with  optional  feature
enhancements  such  as  automatic  call  distribution  and  automated  attendant
functionality, message center and hotel/motel applications, and powerful private
network protocols in both digital and analog versions.

      A line of digital  telephones  designed  for  operation  on the SX-200 and
SX-2000 was released in 1998.  The Superset  4000 line  introduced  new features
such as a full duplex hands-free  speaker phone,  touch sensitive soft keys, and
the  ability  to attach  analog  devices,  such as a fax  machine  or  secondary
telephony device via an Analogue Interface Module. In Fiscal 2000, the style and
functionality  of this product line was carried forward to Mitel's new family of
IP-based voice terminals.

      Voice-over-Internet-Protocol ("VoIP") Systems

      With the convergence of data and voice  infrastructures,  Mitel is focused
on  developing  convergent  solutions  for the business  enterprise.  Management
expects  that  this  converged  infrastructure  should  provide  customers  with
significant  efficiency  improvements  in the future.  Customers  are seeking to
improve their current voice  systems  while  leveraging  the  advantages of open
computing  platforms and operating  systems.  The Company works with a number of
industry   forums  and   industry-leading   partners   in  the  voice  and  data
communications   field   to   advance   the   convergence   of   computing   and
telecommunications technologies.

      In Fiscal 2000,  Mitel took the next step in its converged  voice and data
networking  strategy with the  introduction  of VoIP systems that use IP to send
voice  calls over the same local or wide area  networks  that  connect  personal
computers and servers. Specifically,  Mitel introduced its Data Integrated Voice
Applications ("DIVA")  architecture for the extended enterprise,  as well as the
Ipera  2000.   Mitel's  DIVA  architecture  is  the  foundation  for  delivering
software-only IP business applications,  and is the bridge between the Company's
existing  PBX   platforms   and  its   next-generation   IP  products.   Mitel's
architectural approach is based on a switched IP core that provides a full range
of IP values,  including  scalability,  robust switching and routing.  The Ipera
2000 is based on Mitel's  DIVA  architecture  and  delivers  the same  extensive
functionality as the SX-2000 PBX. Management believes that the Ipera 2000 is the
first VoIP product in the  communications  industry to offer 99.999  percent (or
"five  nines",  an industry  term for the level of  reliability  expected in the
telephone  network)  reliable  call  control and  management.  The Company  also
introduced  two new IP  telephones:  the  SUPERSET  4015(TM) IP and the SUPERSET
4025(TM) IP. The  foundation for Mitel's IP product  development  program is its
"No Compromise" IP strategy,  predicated on proven  functionality and investment
protection, and the delivery of solutions that do not compromise on the quality,
functionality and reliability of traditional voice solutions.

      In Fiscal 2000, Mitel announced a marketing and technology  agreement with
Symbol  Technologies,  Inc. ("Symbol") to deliver a new converged voice and data
solution  that  combines  Mitel's  H.323-compliant  voice  gateway with Symbol's
Spectrum24  wireless local area network and NetVision  VoIP mobile  phones.  The
combined  solution  resulting  from this  agreement  will offer one of the first
end-to-end,  standards-based  enterprise  networks for voice and data  extending
traditional,   wired   networks   with   wireless  LAN  network  and   telephony
capabilities.

      Mitel is also working with  Ericsson  Inc.  ("Ericsson")  to deliver a new
integrated  wireless  office  solution with PBX  functionality.  The system will
combine Ericsson's Mobile  Advantage(TM)  Wireless Office and Mitel's Ipera 2000
to address the needs of both wired and wireless voice communication  services in
small-  and  medium-size  enterprises.  The  wireless  office  system  with  PBX
integration  provides enterprise users with one telephone and one number for all
their business communication needs, regardless of location.

      The Mitel XpressOffice  family of high performance Remote Access solutions
supports  both  data and  voice for  remote  and  central  site  locations.  The
technology features 8:1 data compression plus Intel RISC based processing power.
Mitel's  XpressOffice  family of products is aimed at the burgeoning  market for
teleworking and location  independent  workers.  Full enterprise  voice and data
functionality  is  delivered to the remote user  wherever  basic rate service is
available.  Mitel  believes  XpressOffice  is an ideal remote agent solution for
Call Centers.

      Applications

      Mitel develops  applications software and interfaces that add value to the
PBX at the  desktop  and  workgroup  level  and  take  advantage  of  converging
computing and telecommunications technologies.


                                       9

      Natural speech  recognition is a new application  thrust for Mitel.  Using
the human voice to interact  with and command  computers has long been a goal of
scientists  and  engineers  who  recognize  that voice is the most  natural  and
intuitive  user  interface  possible.  Management  believes that natural  speech
recognition  technology will  increasingly  become an important PBX application.
The specially designed  conversational systems built around this technology will
allow  words and  phrases  spoken  over the  telephone  to serve as  commands to
perform a variety of tasks,  such as  selectively  routing  incoming  calls.  In
Fiscal  2000,  Mitel  introduced  the Impresa  Speak@Ease  Attendant,  the first
product  delivered  as  part of the  Company's  speech  processing  applications
strategy.  Speak@Ease  Attendant is an automated  attendant and personal  dialer
application  that is installed on a Mitel PBX. The  application  allows incoming
callers or employees to connect to  individuals  simply by speaking the person's
name or department.  Speak@Ease  Attendant includes security features based on a
voice signature and offers a secure, customized dialing list.

      Call  centers  continue to be a major  application  thrust for Mitel.  The
Company  addresses the call center market with  software  applications  for four
distinct areas:  (i) call  distribution,  i.e.,  intelligently  routing calls to
agents, (ii) agent automation,  i.e., tying network intelligence such as calling
line ID to a database  of  information  that  provides  agents  with a screen of
information on the calling  customer,  (iii) call management,  i.e.,  performing
functions such as measuring the performance targets of agents, forecasting staff
and forecasting call traffic and (iv) features for supporting  interactive voice
response,  web and e-mail  initiated  transactions.  In Fiscal 2000, the Company
introduced the Mitel Impresa Customer  Interaction  Suite, an applications suite
that  enables an  organization  to create a third  generation  call  center that
improves the level of customer service and increases operating  efficiency.  The
suite,  consisting of the Impresa  Intelligent  Media Router,  the Impresa Agent
Desktop,  and the Impresa Screen Pop,  provides seamless  interoperability  from
beginning to end of each call.

      Another major  application  focus is  messaging.  Mitel is able to offer a
complete portfolio of voice messaging products to customers. Management believes
that customers view voice messaging as a PBX feature,  thus making it a critical
aspect of PBX sales.  Mitel offers a suite of products that management  believes
meets the  price/value  expectations of its targeted  customers,  from the Mitel
Express  Messenger  card-based  solution  for the  SX-200,  to its stand  alone,
scalable  and  server-based  Mitel  Mail  solutions.  Mitel's  success  in voice
messaging depends on both a tighter integration of the application to the switch
and  continued   enhancements  to  new  developing   technologies  like  unified
messaging.  In Fiscal  2000,  Mitel,  through its  Baypoint  Innovations  group,
introduced the OnePoint  Messenger(TM)  server, a unified messaging system based
on Microsoft(R) Exchange(TM) Server. OnePoint Messenger integrates voice, e-mail
and fax  applications and supports native VPIM v2.0 ("Voice Profile for Internet
Mail"),  allowing  users to send and  receive  voice and fax  messages  over the
Internet or enterprise Intranets.

      The Mitel  Global  Developers  Network  program  seeks to attract  leading
third-party developers to deliver  productivity-enhancing  business applications
that complement Mitel's suite of applications and core switching  functionality.
Developers  who have  expertise and a presence in specific  vertical  markets of
interest to Mitel,  such as lodging,  healthcare and education are encouraged to
develop  applications  that  integrate  with  Mitel's  PBXs to deliver  complete
solutions to the targeted  markets.  Mitel's Global Developers are identified in
the market by the "Mitel Connected" logo.

      Network Access Solutions

      The Network Access Solutions group designs,  markets and sells the SMART-1
call  controller/automatic  dialer  family of products  for the analog,  digital
voice communications and fax long distance telephone markets.

      Mitel recently announced the SMART-1 I2AD ("Intelligent  Integrated Access
Device") for the Voice over Digital Subscriber Line ("VoDSL") market. VoDSL is a
technology that uses the existing  copper pairs in the telephone  access network
to deliver multiple voice channels and high-speed data connections over a single
phone line.  The SMART-1  I2AD is a highly  intelligent  VoDSL  product  that is
installed  by the service  provider


                                       10
<PAGE>

on a customer's  premises,  and connects an analog PBX, Key system, and Ethernet
LAN to a VoDSL  circuit.  Unlike  other VoDSL access  devices,  the SMART-1 I2AD
supports concurrent  attachments to one or more analog Public Switched Telephone
Network (PSTN) trunks in addition to the primary VoDSL connection. Combined with
local call routing  intelligence,  this enables the SMART-1 I2AD to overcome the
existing  limitations of VoDSL service and permits service  providers to control
the voice services they offer.

      In Fiscal 2000,  Mitel announced  agreements for the joint  development of
VoDSL  solutions for  competitive  carriers with three DSL  companies:  Pairgain
Technologies, Inc., Jetstream Communications, Inc., and CopperCom, Inc.

      Public Switching

      The Public  Switching group designs,  markets and sells the GX5000 product
line.  The GX5000  platform is a compact,  sophisticated  switching  system that
offers numerous applications. Among its most common applications are digital end
office  replacements  for U.S.  independent  telephone  companies,  rural public
switched  telephone  network  services,   satellite   communications   gateways,
provision  of a  carrier  network  integrated  front  end for  voice  processing
systems,  and digital  network  overlay  services  for  networks  in  developing
countries.

      With changes in the  regulatory  environment,  Competitive  Local Exchange
Carriers  ("CLECs")  and other  service  providers  are  emerging  as  potential
customers for  end-to-end  solutions  that combine the GX5000  product line with
other Mitel IP-based and broadband products.  In response,  the Public Switching
group  intends to provide  applications  that  support  both  private and public
networks. Management believes that Mitel possesses both the technology and sales
channels to take advantage of this changing environment.

      CLECs   bundle   communications,   information   technology   and  certain
entertainment services for all of the users in a particular service area such as
an  apartment  complex or housing  development.  These  services  generally  are
offered at lower long term costs to such users,  since the CLECs  negotiate more
favorable rates with alternate  network access  providers than could be obtained
by individual users.  Management  believes that a compact system like the GX5000
is an ideal central office product for such an environment.

      Sales, Marketing and Distribution

      The Systems business unit targets its products and services principally to
businesses  requiring  communications  systems  on  their  premises.  Management
believes that Mitel is a major supplier of PBX systems and peripherals to small-
and medium-sized  businesses,  which  management  further believes is one of the
fastest  growing  business  communications  systems  segments  in the  principal
markets served by the Company.

      North America

      In the  United  States,  Mitel  sells  most  of its  PBX  systems  through
wholesale distributors of telephony equipment.  The distributors,  in turn, sell
to independent telephone companies and to interconnect companies. Mitel products
are also sold in the United States to the federal,  state and local governments.
Typically,   the  North  American   indirect  selling  channel  focuses  on  the
small/medium-size enterprise market, with strong penetration into the education,
lodging,  government,  manufacturing and healthcare industries. Mitel also sells
products directly to end customers  through its subsidiary Mitel  Communications
Solutions,  Inc.  ("MC  Solutions"),   primarily  in  the  top  25  metropolitan
statistical areas as determined by the United States Department of Commerce.  MC
Solutions  is a nationwide  sales and service  operation  that sells  integrated
communications  systems and  applications  to large and  strategic  national and
regional accounts, and large single site accounts.


                                       11
<PAGE>

      Mitel maintains an "Elite VAR"(value added reseller) program in the United
States for the  Company's top 130 dealers.  Mitel has an additional  category of
dealer,  the  Platinum  Elite VAR, as the  primary  indirect  sales  channel for
Mitel's advanced convergence solutions. To be designated a Platinum Elite VAR, a
dealer  must  demonstrate  an  understanding  of both  voice and data  networks.
Accordingly,  management  believes that  Platinum  Elite VARs have a competitive
advantage because they can provide customers with "one-stop  shopping" for their
complete  communications  needs.  Both Elite VARs and  Platinum  Elite VARs have
exclusive  access to Mitel's  products such as the SX-2000 PBX.  Platinum  Elite
VARs  have  access  to  applications  that  require  expertise  in  server-based
telephony.  Both also have a  non-exclusive  right to distribute the rest of the
Company's PBX products.  All other dealers,  which number approximately 300, are
classified as Mitel Dealers. Mitel Dealers sell the balance of the Company's PBX
product line.

      In Canada,  Mitel sells its complete range of PBX equipment to independent
interconnect  companies and specific telephone  companies including Bell Canada,
Bell  Canada  Intrigna,  and  Aliant,  which  in  turn  sell to end  users.  The
interconnect companies operate under an Elite VAR and Platinum Elite VAR support
program similar to that in the United States. The VARs sell, install and provide
service  throughout Canada,  marketing Mitel products on a non-exclusive  basis.
Mitel also sells the SX-2000 line of PBX systems directly to end users in Canada
through MC Solutions.

      Mitel sells its SMART-1 and SMART-1 I2AD line of network access  solutions
in North America through selected  distributors  and direct  accounts,  which in
turn sell such products to carriers and alternate carriers.

      Remote access products are sold primarily  through  selected  data-centric
VARs, although the Company plans to add this portfolio to the Elite and Platinum
Elite VARs' products  offering.  Public  switching  systems are sold directly to
independent  telephone  companies in the United States.  Mitel  distributes  the
balance of its Systems  product line through  selected  VARs and OEM  ("original
equipment manufacturer") customers.

      Europe

      Mitel  markets its  Systems  products  under  distribution  agreements  in
several countries in Europe.  The most significant market in terms of revenue is
the  United  Kingdom.  In the United  Kingdom,  Mitel  sells its  communications
equipment to large multinational enterprises through a direct sales organization
(Mitel Solutions Division) to end customers and also indirectly through selected
distributors and dealers. In the United Kingdom,  Mitel serves principally large
corporate customers with specific strengths in the high-end lodging,  utilities,
financial and professional services and publishing industries. To extend Mitel's
distribution  access  to small and  medium-sized  enterprises,  Mitel  sells its
products through an indirect distribution channel.

      In addition,  Mitel markets its line of remote access products to a number
of post, telephone and telegraph companies in Europe.

      Mitel  continued to expand its  distribution  channel across  Europe,  the
Middle East and Africa during Fiscal 2000  principally  through the  iMagination
product  family,   which  management   believes  is  well  suited  for  indirect
distribution targeted at the small to medium-sized enterprise market.

      Management  believes that the Systems  products,  combined with the remote
access product line and Mitel's continuing CTI initiatives,  will allow Mitel to
continue to grow an IT-centric  distribution channel in line with planned future
product developments.

      Mitel sells its SMART-1 and SMART-1 I2AD line of alternate  network access
products directly to key accounts in the United Kingdom.  Such products are also
sold  through  distributors  to  other  customers  in the  United  Kingdom  and,
increasingly,  in continental Europe as the carrier markets are deregulated. The
carrier


                                       12
<PAGE>

market addressed by these alternate network access products is highly influenced
by regulation and tariff structures, and can be impacted by the consolidation of
common carriers.

      Other Markets

      Mitel markets its communication  products directly and under  distribution
agreements in China and other Asia/Pacific  countries,  the Middle East, Africa,
South and Central America, Mexico and the Caribbean.

      Mitel sells its SMART-1 and SMART-1 I2AD line of network access  solutions
products  in  Japan  through  selected  distributors,  which in turn  sell  such
products to carriers and alternate carriers.

      Competition

      Rapid technological change, evolving standards and regulatory developments
characterize the market for Systems products.  Many of the Company's competitors
and potential competitors have greater financial, technological,  manufacturing,
marketing and personnel resources than the Company.  Moreover, the drive towards
the  convergence of voice and data has led to the emergence of a new category of
competitors, which focus on this emerging market.

      In  addition  to Mitel,  the major  suppliers  of PBX  equipment  in North
America include  Nortel,  Lucent,  Siemens AG ("Siemens"),  and NEC America Inc.
("NEC"). Mitel also competes with traditional data communications companies such
as Cisco Systems Inc.  ("Cisco"),  3Com  Corporation,  and smaller niche players
such as Vertical Networks, Inc., which offer server-based communications systems
generally targeted to the small to medium enterprise/branch office market.

      The principal  factors of competition  in the market sectors  addressed by
Mitel include product  performance,  price,  reliability,  ease of expansion and
enhancement,  future product  strategy,  and support of evolving  networking and
computer  telephony  open  standards.  Management  believes that Mitel's  target
customers  also  regard  the ease with  which  they can do  business  with their
suppliers as an increasingly important factor in the selection process.

      Management  believes  that Mitel  compares  favorably  with respect to the
foregoing  factors  against its  competitors,  some of which are larger and have
more  resources  than Mitel.  Mitel has been a  significant  PBX supplier to the
under-100 line segment of the market in North America since the early 1980s.  In
this  segment,  Mitel  competes  with  hybrid key systems  manufacturers,  other
manufacturers of PBX products,  and  manufacturers of server-based  "all-in-one"
communications systems, referred to as "un-PBXs" and "LAN PBXs".

      The Company's basic PBX hardware  business has experienced and is expected
to  continue  to  experience  a  price-driven  competitive  phase,  typical of a
commodity  product,  as  equipment  replacement  cycles for  TDM-based  products
continue  to slow  down.  However,  Mitel  provides  its PBX  customers  with an
"intelligent  evolution"  from  digital to  broadband  technology  by  designing
communications systems building blocks that are modular and easily upgradable.

      According to Phillips  InfoTech,  based on calendar 1999 market  research,
Mitel held approximately 8.9% of the total United States PBX market and was tied
for fourth place with NEC in overall market share.  Lucent,  with  approximately
33.2% and Nortel,  with  approximately  29.1%, are the dominant suppliers in the
United States.

      For calendar 1999,  Mitel held  approximately  34.2% of the total Canadian
PBX line  market,  and the number one  position  in the under 1000 line  market,
according to estimates provided by Phillips InfoTech.  The


                                       13
<PAGE>

Company is benefiting from an agreement signed in April 1999 with Bell Canada to
sell the  SX-2000 in Ontario and  Quebec.  Mitel also sells its systems  through
most Canadian telephone companies.  Mitel's prime competitor in Canada is Nortel
Networks.

      Leading  communications  equipment  suppliers  to the  European PBX market
include Alcatel Alsthom Compagnie ("Alcatel"),  Siemens,  Telefonaktiebolaget LM
Ericsson ("Ericsson"), Philips Electronics NV and Nortel. In the United Kingdom,
Mitel's main competitors are Nortel, selling through British  Telecommunications
plc, Siemens, Ericsson, and Alcatel.

      In the  Asia/Pacific  PBX  market,  most  major  communications  equipment
suppliers have a presence and competition is intense.  Management  believes that
Mitel  compares  favorably  to  the  competition  in  terms  of  price,  product
performance and after-sale service provided by its appointed local distributors.

      For  network  access  solutions,  competition  varies  by  market  and  by
application  (voice or fax),  because the worldwide long distance calling market
is in transition as a result of deregulation and consolidation of carriers.

      The U.S. rural central office market is dominated by two suppliers: Nortel
and  Siemens  Stromberg  Carlson.  The  switching  market  is  sensitive  to new
technology evolution.  Internationally,  large, multinational corporations, such
as Alcatel, Siemens, Ericsson, Nortel, NEC and Lucent dominate the rural central
office  market.   Most  suppliers  generally  offer  equipment  with  comparable
technical functionality.

      Manufacturing

      Mitel's  Systems  products  are  manufactured  in  Canada  and the  United
Kingdom.  Mitel's  manufacturing  operations  in all  locations  concentrate  on
quality,  cost and delivery,  with special  attention  paid to constant  process
improvement.  All of Mitel's systems manufacturing  facilities and their quality
management  systems are  certified to the strict  standards  established  by the
International Standards Organization of Geneva, Switzerland ("ISO").

      On March 1, 1999, the Company  announced plans to phase out  manufacturing
operations  in its  Ogdensburg,  New York  facility.  Products  manufactured  in
Ogdensburg  were  transferred  to facilities in Canada and the United Kingdom by
the end of July 1999. The Company's repair operations remain in Ogdensburg.

      The Company continues to invest in manufacturing related technologies that
aim to improve production yields, productivity and overall product quality.

      Mitel purchases substantially all of the parts and components for assembly
of its Systems  products from a large number of suppliers  through a coordinated
world-wide  sourcing process.  Mitel also obtains certain of the  semiconductors
required in its Systems  manufacturing  from the  Semiconductor  group.  Mitel's
suppliers  are  subject  to audit by the  Company  on a  regular  basis  and are
required to meet the Company's  strict  standards with regard to cost,  quality,
delivery  and  performance.  The  highest  level of  achievement  against  these
standards  results in the  attainment  of "Certified  Supplier"  status by those
involved in this program.  No single supplier  accounts for more than 10% of the
Company's total purchases and to date, Mitel has not experienced any significant
manufacturing delays relating to the availability of material.

      Research and Development

      Mitel's  Systems R&D  programs  are  primarily  directed in the  following
areas:


                                       14
<PAGE>

      o     Call Processing:  This program involves three main initiatives.  The
            first is to  enhance  Mitel's  call  control  engines  on the SX and
            Imagination platforms (including remote access) to meet the needs of
            enterprise  customers.  The second is to leverage  the rich  feature
            base into an IP centric  platform.  The third is to consolidate  the
            number of call  processing  platforms to a single stream to increase
            the productivity of the R&D  organization.  Mitel's DIVA links these
            three elements into a single development program.

      o     Desktop  Appliances:  The program  focuses on the  development  of a
            series of desktop  devices  for both TDM and IP to provide  enhanced
            access to  converged  networks.  The R&D focus is on  extending  the
            value of existing TDM phones, practical IP phones, conference units,
            PDAs,  cell phones,  desktop  software and other  personal  tools by
            leveraging  the power of enterprise and wide-area  networking.  This
            involves  extensive  work  in  highly  integrated  silicon  devices,
            optimized   man-machine    interfaces   and   the   cost   effective
            implementation of standards.

      o     Applications:   Significant   investment  is  being   directed  into
            development  of  applications   which  leverage   Mitel's   in-depth
            knowledge  of  desktop  and  call  processing   technology  in  both
            converged  and TDM  environments.  Significant  R&D  effort is being
            directed toward the extension of existing  messaging and call center
            product families to address current market needs. With the advent of
            converged IP systems,  a whole new class of  applications  are being
            pursued  which  can bring new  value to  customers  simply  and cost
            effectively.  Mitel is investing in practical  applications of voice
            recognition  technology  which,  when coupled  with open  standards,
            greatly  increases  the number  applications  best served by a voice
            based interface.

      o     Public Networks: Mitel continues to support the GX5000 small central
            office and advanced alternate network ISDN access products. Mitel is
            extending  its  investment  in  its  DIVA  architecture  to  address
            application and call processing  service  provision  within a public
            network  context and  leveraging  the power of emerging  xDSL access
            technology.

      As at March 31,  2000,  Systems  employed  approximately  627 research and
development personnel in Canada, the United States, and the United Kingdom.

      Government Regulation

      PBXs are considered  customer premise equipment ("CPE").  Although the CPE
market in the United States is not regulated,  certain  developments,  which are
described below,  have changed the United States  telecommunications  market. On
February 1, 1996, the United States Congress passed the  Telecommunications  Act
of 1996.  Management  believes that the legislation  will continue to accelerate
the convergence of the communications,  information and entertainment industries
while intensifying competition within those industries. This legislation removes
the line of business  restrictions  on the  Regional  Bell  Operating  Companies
("RBOCs")  and  allows the RBOCs to enter the  manufacturing  sector at the time
they are allowed into long  distance  markets.  For the first three  years,  any
manufacturing  by an RBOC must be  conducted  through a separate  affiliate  and
procurement from the subsidiary must be on a non-discriminatory  basis. While it
is not improbable  that an RBOC will  eventually  meet the minimum  criteria for
entry  into the long  distance  market  and  thereby  become  eligible  to begin
manufacturing,  it appears  unlikely,  at this time,  that the majority of RBOCs
will commence both such activities in Fiscal 2001.

      Although there can be no assurance,  management  does not expect that such
legislation  will have a material  adverse  effect on the  Company's  results of
operations  in Fiscal 2001, in light of the existing  competitive  conditions in
the United States market and the significant conditions required to be satisfied
by the RBOCs under such legislation before they can commence manufacturing.

      The second  development  is a  proposed  regulation  by the United  States
Federal  Communications  Commission  ("FCC") which will impose certain  enhanced
"911" application requirements ("E-911") on CPE


                                       15
<PAGE>

manufacturers.  Certain states have already  imposed such  requirements  and the
Federal  government  in  the  United  States  is  poised  to  do  likewise.  The
telecommunications  industry  is  advocating  a  proposed  settlement  that,  if
adopted,  would be favorable to CPE manufacturers,  including Mitel, with regard
to these proposed  regulations.  The benefits to Mitel from the settlement would
result  principally from the availability of certain  exemptions with respect to
lower line sizes as well as  positive  grandfathering  provisions.  The State of
Illinois is likewise adopting favorable aspects of the industry's position as it
amends its statute with respect to E-911.  Illinois is in the forefront of state
efforts in this regard.

      The FCC also imposes  installation  and  equipment  standards  for CPE and
requires that all CPE marketed in the United  States be  registered  with it and
comply  with these  standards.  The Company  believes  that it is  currently  in
compliance with these requirements in all material respects.

      The United  States  government  promulgated  regulations,  which came into
effect on  November  1,  1998,  regarding  accessibility  of  telecommunications
equipment  and  customer  premises  equipment,  pursuant  to Section  255 of the
Telecommunications  Act  of  1996.  Although  there  can be no  assurance,  such
regulations  were  anticipated  by Mitel and  management  believes  that ongoing
compliance  with such  regulations,  as they are  phased  in,  should not have a
material adverse effect on the results of Mitel's operations in Fiscal 2001.

      The  Company  cannot now  anticipate  what  impact  such  legislation  and
regulations may have on the results of its operations beyond Fiscal 2001 or what
further regulatory changes will occur in the communications equipment market and
the competitive environment as a consequence of actions by the legislature,  the
FCC or the courts.

      The Canadian  Radio-television and Telecommunications  Commission ("CRTC")
is the  regulatory  agency in Canada  governing  most of the  telecommunications
industry.  Currently,  the CPE  market in Canada is an  unregulated  market  and
Canadian  carriers do not need CRTC  approved  tariffs in order to sell terminal
equipment.

      The   liberalization   of  access  to   telecommunications   networks  and
competition in  telecommunications  services in the European Union has proceeded
at a steady pace through  initiatives of the Member  States,  as well as through
deregulation  initiatives of the European  Commission.  The deregulatory process
has increased  competition  and opened  markets for  telecommunications  vendors
throughout Europe.

      MITEL SEMICONDUCTOR

      Mitel Semiconductor designs and manufactures  microelectronic devices that
help move  voice,  data and images over the world's  wired,  wireless  and fiber
optic networks.  Mitel  Semiconductor's  vision is to be known as the "Broadband
Connectivity Company" supplying  connectivity  solutions to wireline,  wireless,
and optical markets with a focus on QoS.

In the medical market, Mitel supplies  Applications Specific Integrated Circuits
("ASICs")  for hearing aid and  pacemaker  devices.  With its unique 0.35 micron
ultra low voltage CMOS process,  Semiconductor is extending this core competence
into the emerging portable medical instruments and communicating  medical device
markets.

      Industry

      The primary  markets for  Semiconductor's  products are the network access
and user access markets for the convergent  communications equipment and medical
devices industries,  which represent major end-markets for these products.  Each
of these industries is expected to grow economically and evolve  technologically
over the next several years,  which  management  believes should provide revenue
growth opportunities to Mitel. The


                                       16
<PAGE>

increased  requirements  of end users,  coupled  with new  opportunities  should
continue  to  drive  the  demand  for  network   communications   equipment  and
infrastructure. The deregulation of telecommunications services in many parts of
the world has resulted in the licensing of new operators and service  providers,
many of which need new equipment and facilities.  The emergence of new operators
and service  providers has, in turn,  intensified the  competitive  environment,
forcing  existing  operators and service  providers to accelerate  their capital
spending  plans.  The growth of the  Internet and  uncontrolled  increase in the
bandwidth  needed for new  applications  is also driving  demand for new capital
spending.  In addition,  the low  penetration  of telephone  service in emerging
countries  is a strong  driver  for wired and  wireless  communications.  In the
United  States,  information  technology  has been  growing as a  proportion  of
capital spending. Server growth, in particular,  has been spurred by the flow of
information and the requirement  within IT departments to make  information more
accessible,  and its provision  more  cost-effective.  Management  believes that
these developments represent significant new market opportunities for Mitel over
the next several years.

      Products and Customers

      Mitel  manufactures  and sells  semiconductor  products  in the  following
categories of communications ICs: broadband networking;  optical communications,
subscriber access,  wireless;  digital  television;  and communications  Systems
Level  Integration  ("SLI").  Mitel also  addresses the medical  market with its
medical ASICs.  The Company also provides foundry services to third parties on a
contract basis. Mitel's  semiconductor revenue accounted for 43%, 43% and 36% of
the Company's total revenue in Fiscal 2000, 1999, and 1998, respectively.

      Mitel's integrated circuits are microelectronic component parts that offer
the high feature  integration,  low power  consumption  and low  physical  space
required for the design of advanced  communications  systems.  Such products are
designed to provide  advanced  communications  and control  functions for a wide
variety of electronic products and systems.

      Mitel's semiconductor  products are primarily  non-commodity,  specialized
products that are  proprietary  in design and used by multiple  customers.  As a
result, management believes that Semiconductor's revenues are not as susceptible
to the volatility and cyclical nature of revenue  generally  associated with the
commodity-oriented segments of the semiconductor industry.

      Full custom semiconductor products rely on an original design and a unique
interface.  Such products  take longer to design but  generally  remain as a key
component  in the end  product for the  duration of its life cycle.  Semi-custom
products are  proprietary  products  that have been altered to meet the specific
requirements  of  individual  customers.  Commodity  products  are "pin for pin"
replacements  that sell  primarily  on the basis of  performance,  availability,
quality  and price.  Mitel's  products  are  mostly  full  custom.  Accordingly,
management  believes  that once  designed  into a  customer's  product,  Mitel's
products  form an integral  part of the  customer's  system and are difficult to
replace,  as replacement would require some redesign of the system. A portion of
the  Semiconductor  business  unit's  product  output is supplied to the Systems
group for use in the Company's systems products. The revenue from these products
is excluded from the calculation of Mitel's consolidated revenue and the revenue
of the Semiconductor unit.

      Semiconductor  has a diverse and established  base of over 3,300 customers
in a wide  spectrum  of end  markets,  including  leading  manufacturers  in the
telecommunications, data communications, and medical sectors.

      Communications


      The microelectronics market for communications is large - comprising local
area networking, wide area networking, optical communications, cellular, set-top
boxes, and communications processors,  among others. Within this diverse market,
the Company  focuses on  providing  a range of  solutions  that  shape,  signal,
transport


                                       17
<PAGE>

and switch  real-time  traffic in the public  network,  the  Internet and in the
wireless,  cable and optical networks. The Company's  communications IC business
can be grouped in two broad areas: (i) network access and, (ii) user access.

      Network Access

      Broadband Networking

      Mitel  Semiconductor  develops and  manufactures  complete,  silicon-based
solutions designed to improve  performance and integration levels for WAN access
equipment.  Market  drivers  such  as  carrier  deregulation,  Internet  growth,
increased  wireless  subscription  and the  availability  of venture capital are
driving demand for next generation  broadband  network access  equipment such as
Integrated Access Devices,  Carrier  Gateways,  DSL Access  Multiplexers,  Third
Generation  Wireless  Systems,  Remote  Access  Concentrators,  Next  Generation
Digital Loop Carrier and ATM Edge Switches. Mitel's competencies in the areas of
switching,  convergence,  timing and transmission enable it to deliver converged
connectivity solutions for these applications.

      Switching

      Mitel's  digital switch product  family  expanded in Fiscal 2000.  Mitel's
MT90826 Quad Digital  Switch (a 4096 x 4096  channel  switch)  received the 1999
Communication  Solutions  Product  of the Year award  from  Technical  Marketing
Corporation. Mitel also recently introduced the MT90866 WAN Access Switch to the
market.  With  the  product's  integrated  PLL  meeting  Bellcore's  Stratum  4E
specification,  this  device  addresses  the  growing  compact  PCI  market  for
carrier-class  access  equipment.  Mitel also introduced the MT90812  Integrated
Digital  Switch  designed  to provide a  system-on-a-chip  solution  for smaller
enterprise  switching  applications,  such as SOHO CTI  systems,  key  telephone
systems and PBXs.  These  products  provide  solutions  for low-end,  enterprise
switching  applications  and also network access  equipment,  required to handle
voice and Internet data traffic.

      Convergence

      ATM is a key underlying  technology for integrating WAN access services in
which voice, video and Internet traffic are delivered to the home,  business and
government.  Mitel  addresses  this market with  high-density  voice-over-packet
solutions for the local loop and central office. Leveraging its strengths in the
areas of QoS,  latency  minimization  and clock  recovery,  Mitel delivers voice
processing SARs ("Segmentation and Reassembly sublayer") designed to convert TDM
traffic to ATM in access and  carrier  class  equipment  such as  concentrators,
multiplexers and multiservice switches.

Entering  this  market over two years ago with the  introduction  of the MT90500
AAL1 (AAL means ATM  Adaptation  Layer;  1 is for constant bit rate traffic) SAR
designed for constant bit rate  traffic,  Mitel is  significantly  expanding the
line with the following new SARs:

      o     The  MT90503  is an AAL1 SAR which can  process  greater  than 2,000
            simultaneous   voice  calls  and  can  provide  channel   associated
            signaling,  enabling customers to deliver circuit emulation services
            ("CES",  the transporting of TDM services  transparently over an ATM
            network) for assured QoS and increased network interoperability.

      o     The MT90528 AAL1 SAR delivers  circuit  emulation  services  over 28
            T1/E1 ports, supporting new standards like dynamic bandwidth circuit
            emulation services ("DBCES").  In addition,  it can be programmed to
            support structured or unstructured data for any access applications.


                                       19

      Timing

      Stable,  reliable timing is critical to networking.  Mitel has a family of
digital PLLs which provide timing for CPE and central office equipment, allowing
customers to meet T1 and E1 timing  interface  requirements  all over the world,
while  ensuring  consistent  jitter-filtering  characteristics  over a range  of
temperature and voltage.

      This year Mitel is sampling  the MT9043 and MT9045,  two 3.3 volt  digital
PLLs  used to  provide  reliable  and  stable  clocks  that  meet  the  required
telecommunications  specifications  in the presence of  impairments on the input
timing signals.  The MT9043 is a reference switching PLL intended for line-timed
networking equipment, such as PBXs, wireless base stations and Integrated Access
Devices with more than one  interface.  The MT9045 is a reference  switching PLL
with a holdover  capability  intended  for  externally-timed  equipment  such as
remote access concentrators and central office carrier gateways that is required
to be highly reliable.

      Transmission

      For T1, E1 and J1, the world's dominant wide area network  infrastructure,
Mitel is  expanding  its  family of  framers to include a number of 3 volt parts
designed to meet all worldwide standards,  including North American T1, Japanese
J1,  and E1 - the  protocol  used in the  rest of the  world.  With the need for
higher  bandwidth  links,  customers are  demanding  combo chip sets with higher
integration and high channel  density.  The MT9076 combines a T1/E1/J1 framer, a
PLL and a long  haul  line  interface  unit  (LIU)  into a  single  package  for
low-density  applications.  For higher density  applications the MT9072 delivers
eight T1/E1/J1 framers in a single package.

      Optical Communications

      Mitel supplies VCSELs,  Light Emitting Diodes ("LED"), PIN photodetectors,
PIN/Pre-amp  combos and duplex  devices.  These  devices,  which are built using
gallium  arsenide  and  indium  phosphide  technologies,  allow  Mitel  to offer
products to drive fiber optic cable in data network applications such as Gigabit
Ethernet, Fibre Channel, Fiber Distributed Data Interface and ATM.

      In Fiscal 2000,  Mitel  announced the 623-family of parallel fiber modules
to serve the emerging  requirements  for  short-reach  optical  interconnect  in
large-scale computing and communication systems.  Management believes the market
for very  short-reach  parallel  fiber  will  grow  significantly  over the next
several years. Parallel fiber modules improve channel cost and density, enabling
the all-fiber  architectures that will displace the current  interconnect scheme
made  up  of  conventional   copper  and   single-channel   fiber  optic  links.
Applications   for  Mitel's   623-family  of  parallel  fiber  modules   include
interconnects from board-to-board,  board-to-optical backplane,  shelf-to-shelf,
and  rack-to-rack  within  and  between  terabit-class  switches,  routers,  and
transport equipment in the central office. The new modules combine Mitel's VCSEL
and Smart OSA packaging  technologies to deliver what management believes is the
industry's best price/performance  ratio. Mitel is collaborating with AMCC, Tyco
Electronics  (formerly  AMP),  and US Conec to enable the 623-family of parallel
fiber modules to seamlessly interface to a range of complementary products.

      Management  believes  that its  customers  are able to derive  significant
benefits from the Company's wide range of broadband  networking  solutions.  For
example,  in the growing high speed IAD (Integrated Access Devices) markets such
as terabit  routers,  Mitel  Semiconductor's  customers are using its Phase Lock
Loops ("PLLs"), high speed T1/E1 interfaces,  TDM switches, echo cancellors, and
emerging 623 series optics.

      User Access

      Subscriber Access

      Mitel has  established a line of analog and digital  switching  integrated
circuit  products that provide a high  capacity for switching  voice and data in
telephony applications. In Fiscal 2000, Mitel introduced a complete chipset that
delivers voice quality to enterprise-level VoIP systems.  Mitel's Internet Phone
chipset combines all of the hardware and software  building blocks necessary for
solutions that meet the  performance,  functionality  and cost  requirements for
both telephone  vendors and data  communications  companies seeking to enter the
emerging VoIP market.  Mitel's chipset includes the MT92101 IP phone controller,
the MT92303 dual codec, and the MT933, a 10/100 Ethernet PHY.  Employing Mitel's
Trueplex  technology,  the chipset reduces echoes that result from  transmission
delays inherent in packet-based networks.

      Mitel also launched two silicon SLICs (Subscriber Line Interface  Circuit)
that deliver highly reliable ringing at competitive cost for  telecommunications
access  applications.  The  products  are part of  Semiconductor's  strategy  to
provide a complete range of line card interfaces  between a switching system and
subscriber  loop in short- to  mid-range  telecommunications  applications.  The
MT91600  is  an  analog   device  that  meets  system  cost  and   functionality
requirements  in a footprint  that is smaller than  alternative  solutions.  The
MT91610 is a fully-featured  SLIC that uses an advanced ringing  architecture to
improve  performance,  while  integrating  complete  functionality  into  a very
compact, off-the-shelf device.

      Mitel is a leading supplier of Caller ID receiver  integrated circuits for
the telephony and CTI markets,  and continues to reinforce its position with the
introduction  of new products  which address the low power  requirements  of the
European line powered phone and DECT (digital enhanced cordless telephones) base
station  markets,  as well as the high growth 900MHz  cordless phone market with
enhancements  designed to improve performance of CIDCW ("Caller Identity on Call
Waiting")  services.  The new MT88E46 is a Caller ID / CIDCW  receiver chip that
exceeds Bellcore (now Telcordia) specifications for performance and reliability.

      Mitel  also  manufactures  hybrid  integrated  circuits  that  permit  the
packaging  of  different  technologies  required  by today's  advanced  computer
systems and range in complexity from a simple  collection of passive  components
to an extremely  complex  subsystem  module.  Mitel  supplies  these products as
either standard circuits or as customized circuits designed for and supplied to,
a specific customer. In most cases, the hybrid component either incorporates, or
is designed to work alongside,  other Mitel components,  thereby  increasing the
overall  value of the solution to the  customer.  Some common  applications  for
thick-film  hybrid   microcircuits   are  in  PBXs,   central  office  switches,
multiplexers, cable modems, and set-top boxes.

      Mitel is also a supplier of dual-tone  multi-frequency receiver components
("DTMF"),  which are used for remote control in high-volume applications such as
facsimile and telephone answering machines.

      Wireless

      Mitel is an  established  supplier  of RF and  digital  components  to the
analog and digital cellular market for both base stations and handsets.  Mitel's
Planet chip set, a full  processor-to-antenna  suite for Code Division  Multiple
Access (CDMA) dual-mode  cellular phones,  continued to sell widely.  Mitel is a
volume supplier of both RF and digital components for the digital cellular phone
standards TDMA and CDMA, used in the United States and the Asia Pacific area.

      In Fiscal 2000, Mitel entered the market for  Bluetooth(TM)  devices - the
industry  name for a radio  system  specification  that allows very  short-range
transmission of voice and data between  electronic  devices  without  connecting
cables.  RF devices  built to the  Bluetooth  standard  will enable new wireless
applications such as the transfer of data between computers in a meeting,  and a
wireless  link  between a  Personal  Digital  Assistant  ("PDA")  and a personal
computer   ("PC").   Mitel   announced   it  is   co-developing   a  module  for
next-generation  Bluetooth  systems with  Matsushita  Electronic  Components Co.
Ltd., and Philsar Electronics Inc. of Ottawa (now part of Conexant Systems, Inc.
or  "Conexant").  The module,  which  integrates  a baseband  controller  IC and
software  from Mitel and a radio  transceiver  from  Philsar  with  high-density
packaging and RF expertise


                                       21

from Matsushita,  that management believes will meet the requirements for mobile
and wireless applications in consumer and business electronics.


                                       22

      Digital Television

      The  television is evolving from a medium for  delivering  channels into a
vehicle for delivering  Internet  access,  voice,  video and multimedia into the
home.  Mitel is a major  global  supplier  of RF  components  for tuners used in
digital set-top boxes,  the home gateways that interface  between the television
and the network.  Management  believes  that the Company is known for its "front
end" tuner solutions,  mostly for satellite and cable television systems, and in
Fiscal  2000,  Mitel  introduced  new  silicon  tuner  products  for set-top box
manufacturers.

      Mitel  developed and introduced  the SNIM3  (Satellite  Network  Interface
Module 3), a complete and highly cost-effective  conversion solution for digital
tuning in satellite  set-top boxes. The SNIM3 comprises the SL1914 low-noise amp
(LNA), the SP5769 synthesizer,  the SL1925  direct-conversion  IC, and the VP310
QPSK and FEC chip.  SNIM3  allows  the STB  manufacturer  to place the  complete
front-end  directly on the main motherboard,  thereby reducing costs and product
size for OEM customers.

      For tuners in digital cable set-top boxes, Mitel produced what it believes
to be the world's first silicon solution  enabling the tuner to migrate directly
onto the motherboard using the SL2030 and SL2035 up/down converters and the dual
PLL SP5848. It was also the first up/down conversion chip set manufactured using
a bipolar  silicon  process,  which is less  expensive  and more  reliable  than
traditional solutions based on gallium arsenide technology.

      Mitel also  developed a "front end" for the emerging  digital  terrestrial
television  (DDT) market.  In Fiscal 2000,  Mitel  introduced the SP5730,  a PLL
integrated  circuit that improves the noise  performance  of digital  television
receivers, resulting in clearer reception.

      Mitel has introduced  high-performance  satellite,  cable and  terrestrial
set-top box integrated circuits that deliver performance and cost advantages for
new broadband digital television systems. The SL1935 is one of the world's first
fully  integrated  direct  conversion  single chip tuner  devices for  satellite
set-top boxes.  The SL2100 is a  cost-effective  broadband down converter IC for
use in cable tuner  applications,  integrating  the SL2030 with an I2C PLL.  The
MT350 is a  demodulator  for  terrestrial  set-top  boxes and digital  TVs.  The
product is designed for maximum flexibility within terrestrial  applications and
supports  both  2k  and  8k  modes  of  operation.  Management  believes  that a
key-differentiating  factor for the MT350 is its ability to  identify  broadcast
multiplexes  in a few  tens  of  seconds,  which  enables  extremely  rapid  end
appliance installation.

      Communications SLI

      Mitel Semiconductor has increased its focus on the application of its ASIC
knowledge to Communications  SLI. Today,  Mitel has a 0.18u capability and Mitel
SystemBuilder  IP  portfolio  that will support SLI  offerings in the  broadband
networking, access, wireless, and digital television markets.

      Mitel released the Firefly product, a pre-defined embedded microcontroller
engine fully  integrated into ASIC  methodology,  enabling  customers to develop
their systems and design  around it without the need to see  prototype  silicon.
Mitel also  announced  the  addition of Universal  Serial Bus ("USB"),  Protocol
Control  Information  ("PCI") and  Firewire  cores to Mitel's  proprietary  ASIC
design flow and methodology, Systembuilder, providing the facility for customers
to include advanced,  high-speed bus interface  connections into their ASICs for
networking and communication  applications.  Mitel also began development of its
0.18 micron ASIC and  Application  Specific  Standard  Products  ("ASSP") design
capability  launched in the third quarter of calendar  1999.  This extends Mitel
Semiconductor's  capability  to  offer  customers  ASSP  and  Customer  Specific
Standard Products ("CSSP"),  enhanced by highly differentiated,  market specific
IP and more efficient design flows enabling fast time to market.


                                       23
<PAGE>

      In Fiscal 2000,  Mitel formed a core technology and  engineering  group to
continue the development of market specific IP, design flows and  methodologies,
targeted at the communications market. The group is dedicated to achieving world
class standards in design  productivity,  tools and flows, IP re-use and ease of
use for internal and external customers.

      ASIC business  opportunities  from  customers are now being routed through
Mitel's market  channels,  which can combine the work of the core technology and
engineering  group with their own specialist market segment  knowledge,  thereby
providing   customers  with  access  to  advanced   standard  products  and  the
flexibility to create customer specific variants.  In making this change,  Mitel
Semiconductor  has set up a  special  team to  ensure  that all  customers  with
existing ASIC design and  production  commitments  are continued  uninterrupted.
This team is completing all customer designs and continues to manage the ongoing
manufacturing  and supply of products in  production.  Customers  continue to be
supported  through the Mitel sales  network and the  engineering  and  marketing
staff from this team.

      Medical ASICs

      The  high  cost  of  medical   care  is   generating   opportunities   for
microelectronics-based  products  that  reduce  health-care  costs  and  improve
quality  of life.  Implantable  medical  devices  such as  pacemakers,  wearable
devices such as hearing aids, portable equipment and communicating  devices that
monitor  patients in and outside a hospital are examples of emerging  markets in
which Mitel's experience and skills have immediate relevance.

      Management  believes  that Mitel is a major  supplier of analog  ASICs for
medical  applications.  Mitel's  expertise in ultra-low power,  high-reliability
integrated  circuit design has enabled the Company to make medical  devices with
high performance and exceptionally long battery life.

      Sales, Marketing and Distribution

      The principal  customers for Mitel's  semiconductors  are customer premise
and network  communication  equipment  manufacturers.  Mitel's products are also
marketed to data  communications  suppliers as the  integration of computing and
telecommunications  continues.  Mitel sells its products in over 100  countries,
through a network of 50 independent representatives and distributors and through
a direct sales force.  Representatives  generally have strong relationships with
Mitel's end customers.  These representatives assist with the design of customer
solutions  incorporating  Mitel  products,   which  are  then  supplied  through
distributors. Semiconductor has implemented a strategic account program focusing
on the development of business with the key network  equipment  suppliers in the
industry.  Direct  sales  force  personnel  from each of  Semiconductor's  sales
regions collaborate to manage business with these multinational enterprises.

      The primary markets for the  Semiconductor  group's  products are the fast
growing and technologically driven industries. The telecommunications equipment,
computer  network  server and  medical  device  industries  represent  major end
markets  for  Semiconductor.  Management  believes  that these  industries  will
provide revenue growth  opportunities  to Mitel during Fiscal 2001. In addition,
management believes  Semiconductor's revenue growth will be supported by various
factors  that  continue to drive  demand for  telecommunications  equipment  and
infrastructure.  In  particular,  deregulation  of  telecommunications  services
worldwide has resulted in the licensing of new operators and service  providers,
most of which need new  equipment  and  facilities.  The  emergence of these new
operators has, in turn,  intensified  the  competitive  environment,  frequently
forcing  existing  operators and service  providers to accelerate  their capital
spending  plans.  The increasing  penetration  of telephone  service in emerging
countries is also a strong  driver for both  wireless and wired  communications,
which management believes increases demand for the Company's integrated circuits
for communications applications.


                                       24
<PAGE>

      The  Company  believes  that  one of  its  competitive  advantages  is the
expertise of its applications  groups,  which are located in the United Kingdom,
the United States,  Canada,  Singapore and Japan to serve customers in all parts
of the world.  The  applications  groups  assist  OEMs in  designing  their next
generation  products using Mitel  components.  Mitel  Semiconductor has a strong
record of soliciting  customers with design ideas and obtaining design wins. The
design win cycle  starts when Mitel and/or its  representatives  identify a need
for one of its standard communications products that meet certain specifications
in a customer's equipment design. Once Mitel's product is selected for a design,
the Company  generally is assured of providing the semiconductor for the product
until the product is no longer manufactured.

      North America

      Mitel's  semiconductor  products  (other  than  medical  ASICs and foundry
services) are sold through  representatives  of  manufacturers  and distributors
and,  increasingly,  directly to OEMs. Mitel's sales  representatives,  who deal
directly with the end customer,  assist with the design of systems incorporating
Mitel products.  These products are then supplied through Mitel's  distributors.
To enhance  sales,  major  account  teams target  specific  large  customers for
standard product deliveries. Foundry services are provided from sales offices in
San Diego,  California and Bromont,  Quebec, Canada, with technical support from
Bromont and Plymouth, United Kingdom.

      Europe

      Sales of Mitel semiconductor components in Europe have been made primarily
through its direct sales  channel.  Distributors  also play an important role in
the  European  region and  management  believes  that their share of the overall
business will increase over the next year due to the desire of many customers to
consolidate  their  logistical  demands.   Semiconductor  maintains  technically
qualified  sales teams across the entire region and supports them with a team of
highly  skilled  applications   engineers  based  in  the  United  Kingdom.  The
headquarters of the sales operation is in Swindon,  U.K. An additional  facility
in Paris, France provides ASIC design and sales support for Southern Europe.

      Asia/Pacific

      The  Asia/Pacific   area  is  a  major   geographical   market  for  Mitel
semiconductor  products, with China, Korea, Japan, Taiwan and Malaysia being the
largest markets. Mitel's semiconductor products are also sold in Australia, Hong
Kong,  Thailand,  New Zealand,  Singapore  and the  Philippines.  The Company is
expanding into other emerging markets in Asia Pacific, such as India.

      Mitel maintains  regional  headquarters in Singapore and offices in Japan,
Taiwan, Korea and China for semiconductor  products.  Over 60% of sales in these
areas are achieved through  representatives and distributors.  The sales offices
provide a service linking  customers,  local  representatives  and  applications
support groups that assist OEMs in designing products with Mitel components.

      Competition

      Competition  in the  semiconductor  market is intense,  with new  entrants
continually   coming   into   the   industry.    Rapid   technological   change,
ever-increasing  functionality  due to integration,  a focus on end product cost
reduction,  and evolving standards  characterize the markets for Semiconductor's
products.  Many of  Semiconductor's  competitors and potential  competitors have
greater  financial,  technological,   manufacturing,   marketing  and  personnel
resources  than  the  Company.   Competition  is  based  principally  on  design
expertise,  product  availability,  service  and  support.  Management  believes
Semiconductor  compares  favorably  via  its  focus  on  real  time  networking,
proprietary designs,  and its sales and support network.  Mitel also competes by


                                       25
<PAGE>

offering a focus on intellectual  property in communications  systems and a high
level of system integration capabilities.

      In the communications market,  Semiconductor focuses on the convergence of
real time traffic with data.  Management believes  Semiconductor has substantial
intellectual  property  associated  with  networking  real time  traffic such as
voice.  Converged voice networking requires competencies in regulatory policies,
analog and mixed signal design, specialty processes, and voice quality.

      Semiconductor  primarily designs and markets proprietary products that are
sold to many customers in the wired,  wireless,  and optoelectronic  segments of
the  communications  market  rather  than  competing  with  commodity  products.
Proprietary  designs provide a long design-in cycle with customers and present a
significant barrier to entry.

      Management believes that  Semiconductor's  sales channels and applications
support  compare  favorably to those of its  competitors by providing  worldwide
coverage,  and pre- and post  design-in  support to assist  customers in getting
their products to market quickly.

      Within the Network Access segment,  PMC-Sierra, Inc., Dallas Semiconductor
Corporation,  Lucent,  Infineon  Technologies AG  ("Infineon"),  Motorola,  Inc.
("Motorola"),  Intersil Corporation, Advanced Micro Devices, Inc. ("AMD"), Texas
Instruments  Incorporated,  and Netergy Networks,  Inc. (formerly 8x8, Inc.) are
the Company's main global  competitors in one or more product lines.  Management
believes  that  Semiconductor  competes  favorably  in Network  Access  based on
Mitel's extensive intellectual property rights ("IPR") in converged networks and
in QoS while meeting regulatory and industry standards.

      In the  optoelectronic  segment of Network Access,  competitors in the LED
and PIN diode business sectors include Hewlett Packard Company,  Honeywell Inc.,
Epitaxx  Inc.  and Tyco  Electronics  (formerly  AMP Inc.),  a division  of Tyco
International  Ltd., in North America and Infineon in Germany.  In this segment,
management believes that Semiconductor competes primarily on product quality and
customization  capability.  In the single  channel VCSEL  market,  Semiconductor
enjoys a shared  leadership  position with  Honeywell,  currently the only known
competitor.  In the VCSEL  array  market,  Semiconductor  was first to market to
establish  a  leadership  position.  Management  expects  other  competitors  to
eventually enter this market. Here, Semiconductor competes via sales support and
price  performance.  In  respect  of the VSR  ("Very  Short  Reach")  SMART  OSA
("Optical  Sub-Assembly")  transceiver,  Mitel competes mainly with Infineon and
W.L. Gore & Associates,  Inc. Management believes that  Semiconductor's  smaller
footprint and higher  performance will provide a competitive  advantage in favor
of Mitel.

      Within  the User  Access  segment,  Philips  International  BV,  Infineon,
Toshiba Corporation,  Motorola, Broadcom Corporation, Conexant, Maxim Integrated
Products, Inc., ST Microelectronics,  Inc. ("ST-Micro"),  and Lucent are Mitel's
main  global  competitors  in  one or  more  product  lines.  In  this  segment,
management believes  Semiconductor competes favorably using products designed on
its bipolar processes and by using innovative design techniques on standard CMOS
technologies.

      In  medical   business,   Semiconductor   competes  mainly  with  American
Microsystems,  Inc.,  Medtronic,  Inc.  ("Medtronic  Micro-Rel") and "pure play"
foundries. Management believes that Mitel competes favorably against competitors
through its  expertise in ultra low power design  capability,  custom analog and
mixed signal  processes and Mitel's quality safety audit process.  Semiconductor
sells to four of the top seven medical OEMs worldwide.

      Manufacturing

      Mitel  manufactures  its  semiconductor  products  in  five  manufacturing
facilities  in Canada,  the United  Kingdom and  Sweden.  The  selection  of the
manufacturing  sites for  semiconductors  generally  is dependent on the type of
semiconductor to be manufactured and the required process and technology.

      Mitel's foundry operations also offer specialty  technology  manufacturing
to customer specifications. By building on the Company's mixed-signal integrated
circuit  manufacturing  expertise,  Mitel can offer unique features that are not
widely  available  and  address  niche  markets,  such as  those  for  low-  and
high-voltage  processes,  double-poly  technology,  high precision resistors and
charged coupled devices. Mitel's foundry


                                       26
<PAGE>

operations  serve a growing base of customers in the United States and Europe by
performing sub-contract manufacturing of silicon wafers. Mitel views the foundry
business as a means of enhancing its manufacturing facilities to perform at near
or full capacity  with a diversified  set of  applications  and hedging  against
market trends in any one segment. Mitel intends to increase the foundry business
in  Bromont,  Quebec,  Canada  and in the  Plymouth,  U.K.  facility  to  ensure
world-class manufacturing operations.

      The Bromont  manufacturing  facility uses CMOS  technology for digital and
mixed-signal products. Two production lines are maintained at Bromont. The first
is a 150 mm line capable of 0.5 micron, but is currently operating 0.8 micron to
4.0 micron processes. The Bromont facility also has a 100 mm line capable of 3.0
to 9.0 micron processes. Most of Bromont's wafer production is probed and tested
at the Company's facility in Kanata, Ontario, Canada.

      Thick-film hybrid microcircuits are manufactured at the Company's facility
in Caldicot, Wales, United Kingdom.

      Mitel's manufacturing  facility in Plymouth,  U.K. possesses  leading-edge
CMOS  technology  for  digital  and  mixed-signal  products.  Plymouth's  200 mm
production  line is  capable  of 0.6 and 0.35  micron  processes  and its 150 mm
production line is capable of 0.8 micron processes and above. The Swindon,  U.K.
manufacturing facility uses bipolar technology for RF applications.  In the fall
1999,  the  facility's  100 mm  production  line was  upgraded to produce 150 mm
wafers. The Lincoln,  United Kingdom manufacturing  facility was included in the
sale of the  Lincoln  Power and  Automotive  business  segment.  See the Lincoln
discussion under Recent Events.

      Optoelectronic  components  are  also  produced  at the  Jarfalla,  Sweden
facility using gallium arsenide and indium phosphide processes.  All of the CMOS
manufacturing  operations  previously  carried out at the Sweden  facility  were
transferred to Mitel's other more  technologically  advanced  fabrication  sites
during Fiscal 2000.

      All of Mitel's  semiconductor  manufacturing  facilities and their quality
management systems are certified to the strict standards established by the ISO.

      Research and Development

      Mitel's  current  Semiconductor  R&D  programs are  primarily  directed at
developing  intellectual  property  in  the  areas  of IC  process  development,
communications ICs,  optoelectronic  components,  ASIC design libraries,  SLI or
"System-On-A-Chip", as well as low power and high voltage semiconductors.

      Semiconductor's  process  development  efforts are focused on mixed signal
processes  and yield  improvements  in both Mitel's CMOS and bipolar  processes.
Communications R&D programs include development of intellectual  property in the
areas of ATM, analog line cards, network timing functions,  WAN chips, switching
and voice processing  functions,  the CDMA wireless standard,  paging,  wireless
LANs,  and set-top box  communications  chips.  Optoelectronics  R&D activity is
focused on enhancing Mitel's patented Smart OSA packaging technology, its market
position in VCSELs and array VCSELs for LAN applications, and the development of
optoelectronic  integrated circuits ("OEICs").  Mitel's ASIC unit invests in the
development of digital  libraries for advanced deep  sub-micron  CMOS designs as
well as increased  design  capacity.  Analog ASIC  development is focused on low
power, high reliability advances for medical and space applications.  Mitel also
continues  to invest in the  development  of SLI  techniques  to improve time to
market for both digital and mixed signal applications.

      Semiconductor   maintains  standard  product  design  centers  in  Kanata,
Ontario, Canada; Jarfalla, Sweden; San Diego, California; and Caldicot, Swindon,
Lincoln  and  Boreumwood  in the United  Kingdom.  In addtion,  Mitel  maintains
process development centers in each of its manufacturing facilities.


                                       27
<PAGE>

      As at March 31, 2000,  Semiconductor  employed  approximately 454 research
and  development  personnel  primarily based in Canada,  the United States,  the
United Kingdom and Sweden.

      Government Regulation

      Mitel's Semiconductor  business unit is neither directly nor significantly
affected by current  government  regulation or policy,  although there can be no
assurance  future  regulatory  changes will not affect the  Company's  business,
financial condition or results of operation.

      Other Corporate Information

      Employees

      At May 18, 2000, Mitel employed  approximately  5,740 persons. As at March
31, 2000, Mitel employed  approximately  5,688 persons compared to approximately
6,216  persons  at the end of  Fiscal  1999,  approximately  6,335 at the end of
Fiscal 1998 and  approximately  4,095 at the end of Fiscal 1997. The decrease in
personnel  from the end of Fiscal 1999 to the end of Fiscal 2000 is  principally
due to the sale of the Lincoln  business,  as described  under Business - Recent
Events Divestiture.  Approximately 41% of the Company's employees are located in
Canada,  40% in the United Kingdom,  14% in the United States, and 5% throughout
the other  locations in which Mitel operates.  Mitel considers the  relationship
with its employees to be excellent.

      Certain of the Company's  employees  are covered by collective  bargaining
agreements or are members of a labor union. In the United States,  approximately
178 service  technicians  employed by MC Solutions are unionized,  substantially
all of whom are  represented  by the  International  Brotherhood  of  Electrical
Workers ("IBEW"). MC Solutions completed its most recent labor negotiations with
the IBEW in October  1997.  The  Company's  agreement  with the IBEW  expires in
September  2000.  The terms and conditions of the  agreement,  which  management
considers to be competitive  in the industry,  provide for  cost-of-living  wage
increases  on a  periodic  basis  throughout  the three year term plus area wage
differentials where appropriate. Management considers the Company's relationship
with the union in the United States to be good. There are no pending  grievances
at this time and any past  disputes  were not  considered  by  management  to be
material.

      In the United Kingdom,  approximately 84 employees of Mitel  Semiconductor
Limited  are  unionized.  The unions  representing  the  employees  include  the
Amalgamated  Electrical and Engineering  Union,  the  Manufacturing  Science and
Finance Union and the Transport and General Workers Union. Negotiations are held
annually in July.  Management  considers  the  Company's  relationship  with the
unions in the United Kingdom to be good.

      In Sweden, three unions represent approximately 164 employees.  The Metall
Industriarbetarforbundet union represents approximately 19 production employees;
the Svenska  Industriarbetarforbundet  union represents approximately 111 office
professional  employees;  and  the   Civilingenjorsforbundet   union  represents
approximately 34 other professional  employees.  It is common practice in Sweden
for the  national  unions  to  negotiate  minimum  standards  with the  employer
association,  supplemented by additional terms negotiated by the local branches.
Each  agreement  is for a term of three years and  expires on January 31,  2001.
Management considers the Company's  relationship with the unions in Sweden to be
good.

      Proprietary Rights

      The Company  owns many  patents  and has made  numerous  applications  for
patents  relating  to  communications   and  semiconductor  and   optoelectronic
technologies.  Management believes that the ownership


                                       28
<PAGE>

of patents is an important  factor in exploiting  associated  inventions and for
providing  protection  for its  patentable  technology in the areas  referred to
above.

      The "MITEL"  trademark  and the Mitel  corporate  logo are  registered  in
Canada and the United States and have been registered in certain other countries
where Mitel  conducts  business.  Most of the  Company's  other  trademarks  are
registered or applications for registration have been filed in various countries
where  management has determined such  registration to be advisable.  Management
believes  that the  Company's  trademarks  are  valuable  assets  and  generally
supports  applications  for  registration  for  marks  in  countries  where  the
assessment  of  potential  business  related to the sale of products or services
associated with such marks justifies such action.

      The  Company  also  owns  other  intellectual  property  rights  for which
registration  has not been  pursued.  In  addition  to  applying  for  statutory
protection for certain  intellectual  property rights, the Company takes various
measures  to  protect  such  rights,  including  maintaining  internal  security
programs and requiring certain nondisclosure and other provisions in contracts.

      As  is   the   case   with   many   companies   doing   business   in  the
telecommunications  industry, it is necessary or desirable from time to time for
the Company to obtain  licenses  from third parties  relating to technology  for
Mitel's  products and processes.  No current license is considered by management
to be material to the  Company's  business,  financial  condition  or results of
operations.

      Forward-Looking Statements and Risk Factors

      Certain  statements  in this section and in other  sections of this Annual
Report on Form 10-K contain forward-looking statements within the meaning of the
Private  Securities  Litigation  Reform  Act of 1995 that are  based on  current
expectations,  estimates  and  projections  about  the  industries  in which the
Company operates, management's beliefs and assumptions made by management. Words
such as  "expects,"  "anticipates,"  "intends,"  "plans,"  "believes,"  "seeks,"
"estimates" and variations of such words and similar expressions are intended to
identify such forward-looking statements. These statements are not guarantees of
future  performance and involve certain risks,  uncertainties  and  assumptions,
which are  difficult  to predict.  Therefore,  actual  outcomes  and results may
differ  materially  from results  forecast or suggested in such  forward-looking
statements.  The  Company  undertakes  no  obligation  to  update  publicly  any
forward-looking  statements,  whether  as a result  of new  information,  future
events or otherwise.

      Such risks,  uncertainties  and  assumptions  include,  among others,  the
following:  increasing  price and  product/service  competition  by foreign  and
domestic competitors,  including new entrants; rapid technological  developments
and changes; the ability to continue to introduce  competitive new products on a
timely,  cost-effective  basis;  delays  in  product  development;  the  mix  of
products/services;  changes in  environmental  and other  domestic  and  foreign
governmental   regulations;   protection   and  validity  of  patent  and  other
intellectual  property  rights;  import  protection  and  regulation;   industry
competition;  industry  capacity and other industry  trends;  the ability of the
Company to  attract  and retain key  employees;  demographic  changes  and other
factors  referenced in this Form 10-K. The above factors are  representative  of
the risks,  uncertainties  and assumptions  that could affect the outcome of the
forward-looking  statements.  In addition,  such statements could be affected by
general  industry and market  conditions and growth rates,  general domestic and
international  economic conditions including interest rate and currency exchange
rate fluctuations and other risks, uncertainties and assumptions,  including the
following:

      Technological Changes; Necessity to Develop and Introduce New Products

      The  markets  for the  Company's  products  are  characterized  by rapidly
changing  technology and evolving and competing industry  standards,  changes in
customers, emerging competition, frequent new product


                                       29
<PAGE>

introductions and evolving methods used by carriers and business  enterprises to
manage  communications  networks.  The Company's future success will depend,  in
part,  on its ability to use leading  technologies  effectively,  to continue to
develop its technical  expertise,  to maintain close working  relationships with
its key customers, to develop new products that meet changing customer needs, to
advertise  and market its  products  and to  influence  and  respond to changing
industry   standards   and  other   technological   changes   on  a  timely  and
cost-effective basis.

      There  can  be no  assurance  that  the  Company  will  be  successful  in
effectively  developing or using new  technologies,  developing  new products or
enhancing its existing  products on a timely basis or that such new technologies
or  enhancements  will  achieve  market  acceptance.  The  Company's  pursuit of
necessary  technological  advances may require  substantial time and expense and
there can be no assurance that the Company will succeed in adapting its products
or business to alternate technologies. Failure of the Company, for technological
or other  reasons,  to develop and introduce  new or enhanced  products that are
compatible  with  industry   standards  and  that  satisfy  customer  price  and
performance  requirements  would have a material adverse effect on the Company's
business, financial condition and results of operations.

      In addition,  the Company's competitors may offer enhancements to existing
products or offer new products based upon new technologies,  industry  standards
or customer  requirements,  that have the  potential to replace or provide lower
cost  alternatives to the Company's  products,  which could render the Company's
existing and future products obsolete,  unmarketable or inoperable. There can be
no  assurance  that the Company  will be able to develop new products to compete
with new  technologies  on a timely  basis or in a  cost-effective  manner.  See
"Business-- Mitel Communications  Systems Research and Development" and "- Mitel
Semiconductor - Research and Development".

      Competition

      The markets for the Company's  products are also  characterized by intense
competition. With the development of the worldwide communications market and the
growing demand for related equipment, numerous manufacturers such as the Company
have emerged to offer products for these markets in competition with traditional
communications  equipment  suppliers.  Competition could further increase if new
companies enter the market or if existing competitors expand their product lines
or upgrade existing products to accommodate new technologies and features.  Many
of the  Company's  current and  potential  competitors  have a longer  operating
history and greater technical, manufacturing,  financial and marketing resources
than the Company  and, as a result,  may be able to adapt more quickly or devote
greater resources to changing technological  requirements,  customer demands and
market trends.  Increased  competition may result in price  reductions,  reduced
gross  margins  and loss of market  share,  any of which  would  have a material
adverse  effect on the Company's  business,  financial  condition and results of
operations.  The  Company  believes  that its  ability to  compete  successfully
depends upon elements both within and outside its control,  including successful
and timely  development  of new products and  manufacturing  processes,  product
performance and quality, manufacturing yields and product availability, customer
services,  pricing, industry trends and general economic trends. There can be no
assurance  that the Company will  continue to compete  successfully  as to these
factors. See See "Business-- Mitel Communications  Systems - Competition" and "-
Mitel Semiconductor - Competition."

      Dependence on Key Personnel

      The  Company's  future  success  depends  to a  significant  extent on the
continued  service of its key  technical  and  management  personnel  and on its
ability to  continue  to attract and retain  qualified  employees,  particularly
those  highly  skilled  design,  process  and  test  engineers  involved  in the
development of mixed signal  products and processes.  The  competition  for such
personnel is intense. The loss of the services of the Company's employees or the
Company's failure to attract, retain and motivate qualified personnel could have
a


                                       30
<PAGE>

material  adverse  effect on the  Company's  business,  financial  condition  or
results of operations.  The Company does not have any employment agreements with
its employees.


                                       31
<PAGE>

      Intellectual Property Protection

      The Company's  success and future revenue growth will depend,  in part, on
its ability to protect its intellectual  property.  The Company relies primarily
on patent, copyright,  trademark and trade secret laws, as well as nondisclosure
agreements  and other  methods  to  protect  its  proprietary  technologies  and
processes.  There can be no assurance that such measures will provide meaningful
protection for the Company's proprietary technologies and processes. The Company
has been issued many patents,  principally in the United States,  Canada and the
United   Kingdom,   and  has  filed  numerous   patent   applications   in  such
jurisdictions.  There can be no assurance  that any patent will issue from these
applications or future  applications or, if issued, that any claims allowed will
be sufficiently broad to protect the Company's  technology.  In addition,  there
can be no assurance  that any existing or future patents will not be challenged,
invalidated or circumvented or that any right granted  thereunder  would provide
meaningful  protection or a competitive advantage to the Company. The failure of
any patents to provide  protection  to the  Company's  technology  would make it
easier for the Company's competitors to offer similar products. The Company also
generally  enters  into  confidentiality   agreements  with  its  employees  and
strategic  partners and generally  controls  access to and  distribution  of its
documentation and other proprietary information.  Despite these precautions,  it
may be  possible  for a third  party  to copy or  otherwise  obtain  and use the
Company's  products,  services  or  technology  without  authorization,  develop
similar  technology  independently  or design around the Company's  patents.  In
addition,  effective  copyright,  trademark and trade secret  protection  may be
unavailable or limited in certain  foreign  countries.  Certain of the Company's
customers have entered into agreements  with the Company  pursuant to which such
customers  have the right to use the  Company's  proprietary  technology  in the
event the Company  defaults in its contractual  obligations,  including  product
supply  obligations,  and fails to cure the default within a specified period of
time. Moreover,  the Company often incorporates the intellectual property of its
strategic customers into its design and the Company has certain obligations with
respect to the non-use and non-disclosure of such intellectual  property.  There
can  be  no   assurance   that  the  steps  taken  by  the  Company  to  prevent
misappropriation or infringement of the intellectual  property of the Company or
its customers will be successful.  Moreover,  litigation may be necessary in the
future to enforce the Company's  intellectual  property  rights,  to protect the
Company's  trade  secrets  or  to  determine  the  validity  and  scope  of  the
proprietary  rights of others,  including its customers.  Such litigation  could
result in substantial  costs and diversion of the Company's  resources and could
have a material adverse effect on the Company's  business,  financial  condition
and results of operations.

      Intellectual Property Claims

      The segment of the  telecommunications  market that includes the Company's
products has been  characterized by extensive  litigation  regarding patents and
other  intellectual  property  rights.  As is common  in the  telecommunications
industry,  the Company has been in the past and may in the future be notified of
claims that its products or services are subject to patents or other proprietary
rights of third  parties.  Although  the  Company  attempts  to ensure  that its
products and processes do not infringe such  third-party  patents or proprietary
rights,  there can be no assurance that  infringement  or invalidity  claims (or
claims for  indemnification  resulting  from  infringement  claims)  will not be
asserted or prosecuted against the Company. Periodically, the Company negotiates
with third  parties to establish  patent  license or  cross-license  agreements.
There can be no assurance that current or future negotiations will result in the
Company obtaining a license on satisfactory terms or at all.  Moreover,  license
agreements with third parties may not include all  intellectual  property rights
that may be issued to or owned by the  licensors  and thus future  disputes with
these companies are possible.  In the event an intellectual  property dispute is
not settled  through a license,  litigation  could  result.  Any  litigation  or
interference  proceedings could result in substantial expense to the Company and
significant  diversion  of  effort by the  Company's  technical  and  managerial
personnel.  An adverse  determination  in such  litigation or  proceeding  could
prevent the Company  from making,  using or selling  certain of its products and
subject  the Company to damage  assessments,  all of which could have a material
adverse  effect on the Company's  business,  financial  condition and results of
operations.

      Acquisitions

      Since 1996,  the Company has made strategic  acquisitions.  In the future,
the Company may make further  strategic  acquisitions  and  investments or enter
into  joint  ventures  or  strategic   alliances  with  other  companies.   Such
transactions entail many risks, including the following:  inability to integrate
successfully  such  companies'  personnel and  businesses;  inability to realize
anticipated  synergies,  economies of scale or other value  associated with such
transactions;   diversion  of  management's  attention  and  disruption  of  the
Company's  ongoing  business;  inability to retain key technical and  managerial
personnel;  inability to establish  and maintain  uniform  standards,  controls,
procedures  and policies;  and  impairment of  relationships  with employees and
customers as a result of the integration of new personnel.  In addition,  future
acquisitions  or  investments  by the  Company  may  result in the  issuance  of
additional  equity  or  debt  securities,  significant  borrowings,  significant
one-time  write-offs  and the creation of goodwill or other  intangible  assets.
Failure  to  avoid  these  or  other  risks   associated   with  such   business
combinations,  investments,  joint ventures or strategic  alliances could have a
material  adverse  effect on the  Company's  business,  financial  condition and
results of operations.

      Significant International Operations

      Approximately  93% of the Company's sales in Fiscal 2000 were derived from
sales in markets  outside  Canada and 48%  outside  North  America.  The Company
expects  sales from  foreign  markets to  continue to  represent  a  significant
portion of total sales.  The Company operates five  manufacturing  facilities as
well as sales and technical support service centers in Europe and Asia.  Certain
risks are inherent in international  operations,  including exposure to currency
exchange  rate  fluctuations,  political  and  economic  conditions,  unexpected
changes in  regulatory  requirements,  exposure to  different  legal  standards,
particularly  with respect to  intellectual  property,  future import and export
restrictions,  difficulties in staffing and managing operations, difficulties in
collecting receivables and potentially adverse tax consequences. There can be no
assurance that the above factors will not have a material  adverse effect on the
Company's business, financial condition and results of operations.

      Foreign  Exchange and Interest Rate Exposure and  Concentration  of Credit
Risk

      Because  substantial  portions of the Company's sales,  costs of sales and
other expenses are denominated in U.S. dollars, U.K. pounds sterling and several
other currencies, the Company's results of operations are subject to the effects
of exchange  rate  fluctuations  of those  currencies  relative to the  Canadian
dollar.  Changes in currency  exchange rates may also affect the relative prices
at which  the  Company  and its  competitors  sell  their  products  in the same
markets.  The Company uses financial  instruments,  principally forward exchange
contracts,  in its  management  of foreign  currency  exposures on estimated net
foreign  currency cash  requirements  and on certain  significant  transactions,
generally over the ensuing 12 to 18 months.  All foreign exchange  contracts are
marked to market and the resulting gains and losses are deferred and included in
the  measurement of the related  transactions  when they occur.  These contracts
primarily  require the Company to purchase and sell certain  foreign  currencies
with or for Canadian dollars at contractual rates.

      A  substantial  amount  of the  Company's  long-term  debt is  subject  to
variable interest rates. The Company uses interest rate swap contracts to manage
the interest rate risk. Payments and receipts under interest rate swap contracts
are recognized as  adjustments to interest  expense on a basis that matches them
with the related  fluctuations  in the  interest  receipts  and  payments  under
floating financial assets and liabilities.

      Several major financial  institutions are  counterparties to the Company's
financial  instruments.  It is the  Company's  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  of  these  contracts.  With  respect  to
accounts receivable,  concentration of credit risk is limited due


                                       33
<PAGE>

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 been provided for in the allowance
for doubtful accounts.

      The Company's  operations  could be adversely  affected if it is unable to
guard against currency, interest and credit risks in the future. There can be no
assurance that foreign  currency and interest rate  fluctuations  or credit risk
will not have a material  adverse  effect on the Company's  business,  financial
condition and results of operations.

      Environmental Regulations

      The  Company is subject to a variety  of  federal,  state and local  laws,
rules and regulations related to the discharge or disposal of toxic, volatile or
other  hazardous  chemicals  used in its  manufacturing  process.  Although  the
Company  believes that it has complied with these laws, rules and regulations in
all material  respects  and to date has not been  required to take any action to
correct  any  noncompliance,  the  failure  to  comply  with  present  or future
regulations  could result in fines being  imposed on the Company,  suspension of
production  or a cessation of  operations.  Such  regulations  could require the
Company to acquire significant  equipment or to incur substantial other expenses
to comply with environmental regulations.  Any failure by the Company to control
the use,  disposal  or storage  of or  adequately  restrict  the  discharge  of,
hazardous  substances could subject the Company to future  liabilities and could
have a material adverse effect on the Company's  business,  financial  condition
and results of operations.

      Regulatory Requirements

      The sale of certain of the Company's  Systems  products may be affected by
governmental regulatory policies, the imposition of carrier tariffs and taxation
of telecommunications  services.  These policies are under continuous review and
are subject to change.  Regulatory  authorities  may prohibit  sales of products
that fail to comply with these  regulations  until the Company makes appropriate
modifications.  There can be no assurance that the Company will be successful in
obtaining or maintaining the necessary regulatory approvals for its products and
its  failure  to do so could  have a material  adverse  effect on the  Company's
business, financial condition and results of operations.

      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  will
eliminate  or modify  many  regulatory  restrictions  in the  telecommunications
market.  Deregulation may facilitate the increasingly  competitive  offerings by
communications  services  providers.  In  addition,  RBOCs are now  permitted to
manufacture  and sell  telecommunications  equipment  under certain  conditions.
Given the  substantial  resources  and large  customer  base of the  RBOCs,  the
Company could face  competition  from these companies  should they satisfy these
conditions and elect to manufacture  networking products.  See "Business-- Mitel
Communications  Systems  -  Competition",  "--  Mitel  Communications  Systems -
Government   Regulation",   "-Mitel   Semiconductor  -   Competition",   "-Mitel

      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.

needs for the foreseeable future.

      Item 3. Legal Proceedings

      Mitel is a  defendant  in a number  of  lawsuits  and party to a number of
other proceedings that have arisen in the normal course of its business.  In the
opinion of the  Company's  in-house  legal  counsel,  any monetary  liability or
financial  impact of such  lawsuits  and  proceedings  to which  Mitel  might be
subject  after final  adjudication  would not be  material  to the  consolidated
financial position of the Company or the results of its operations.

      Item 4. Submission of Matters To a Vote of Security Holders

      None.

      SHAREHOLDERS

      There were 114,123,921 common shareholders of record as at May 18, 2000.

      DIVIDEND POLICY

      The Company has not declared or paid any  dividends  on its common  shares
and the Board of Directors  anticipates  that,  with the  exception of preferred
share  dividend  requirements,  all  available  funds  will  be  applied  in the
foreseeable  future to finance  growth and  improve  the  Company's  competitive
position and profitability.

      Pursuant  to the  terms of the  $2.00  Cumulative  Redeemable  Convertible
Preferred Shares,  1983 R&D Series (Preferred Shares - R&D Series),  the Company
will not be permitted to pay any dividends on common


                                       36
<PAGE>

shares unless all dividends  accrued on the preferred  shares have been declared
and paid or set apart for payment.

      Pursuant to the terms of the credit agreement  described in note 11 to the
consolidated financial statements, the Company is required to maintain a minimum
net worth,  thereby limiting the amount of dividends that could be paid out. The
preferred share dividend does not violate this covenant.  Since the Company does
not anticipate any dividends on its common shares,  the covenant is not expected
to have an impact on the dividend policy.

      Dividends  paid by the  Company to common  shareholders  not  resident  in
Canada would generally be subject to Canadian  withholding tax at the rate of 25
percent or such lower rate as may be provided  under  applicable  tax  treaties.
Under  the  Canada - United  States  tax  treaty,  the rate of  withholding  tax
applicable  to such  dividends  paid to  residents  of the United  States  would
generally be 15 percent.

      Item 6. Selected Financial Data

           (in millions of Canadian dollars, except per share amounts)

      The following table is derived from the consolidated  financial statements
included  elsewhere  herein,   which  have  been  prepared  in  accordance  with
accounting  principles  generally  accepted  in Canada  (Canadian  GAAP).  These
principles also conform,  in all material respects,  with accounting  principles
generally  accepted in the United States (U.S. GAAP) and the requirements of the
SEC,  except as more fully  described in note 23 to the  consolidated  financial
statements.

      Item 7. Management's  Discussion and Analysis of Financial  Conditions and
Results of Operations

      (in millions of Canadian dollars, except per share amounts)

The  following  discussion  and analysis  explains  trends in Mitel's  financial
condition  and results of  operations  for the fiscal year ended March 31, 2000,
compared with the two previous fiscal years. This discussion is intended to help
shareholders  and other readers  understand the dynamics of Mitel's business and
the key factors  underlying its financial  results.  The consolidated  financial
statements,  notes to the consolidated  financial  statements and  supplementary
information  constitute an integral  part of, and should be read in  conjunction
with,  this  management's  discussion  and  analysis.  Readers  may wish to make
reference to the glossary of terms on page 20 of the Annual  Report to assist in
their  understanding of this  discussion.  Net income for the three fiscal years
ended March 31, 2000;  March 26, 1999; and March 27, 1998, as determined by U.S.
generally accepted accounting  principles,  is detailed and discussed in note 23
to the consolidated financial statements.

Recent Significant Events

On June 7, 1999, Mitel announced it would make a normal course issuer bid for up
to  5,835,645  common  shares  (5%  of  116,712,906  common  shares  issued  and
outstanding  at May 28,  1999).  These  purchases  took place on the open market
through the stock exchanges of New York,  London,  Toronto and Montreal pursuant
to the normal course  issuer bid filed with the Toronto and Montreal  exchanges.
As at March 31, 2000,  3,383,800  common shares were  purchased and canceled for
cash consideration of $36.4, including costs to acquire the shares.

On January 19, 2000,  Mitel  completed  the sale of its Lincoln  Automotive  and
Power business  segment  ("Lincoln") for total  consideration of $12.0. The sale
concluded a formal plan  announced on April 22, 1999, to dispose of this segment
as part of Mitel's efforts to focus on its core  communications  business.  As a
result of the sale, the Company recorded additional after-tax provisions of $8.0
as a loss from discontinued operations in the third quarter of Fiscal 2000.

RESULTS OF OPERATIONS

Mitel  is  a  global   provider  of  converging   voice  and  data  systems  and
applications,  and specialty  semiconductors  for the  communications  industry.
Mitel operates through two reportable  business segments - Mitel  Communications
Systems ("Systems") and Mitel Semiconductor ("Semiconductor").

Mitel  sells  its  products  through  both  direct  and  indirect   channels  of
distribution.  Factors affecting the choice of distribution include end-customer
type, the level of product complexity and integration requirements, the stage of
product  introduction,  geographic presence and location of markets,  and volume
levels.

Mitel   Communications   Systems  provides   enterprises  with  voice  and  data
communications systems; complete private networks,  including remote teleworking
solutions;  unified messaging and call center applications;  and CTI systems and
applications.  It also supplies  competitive carriers with public network access
products.

Mitel Semiconductor specializes in connectivity solutions for the communications
and medical  industries  with a product range that includes  components for both
wired and wireless  networks;  microelectronics  for enabling the convergence of
voice and data;  optoelectronic  devices for high-speed  Internet  systems;  and
application-specific integrated circuits ("ASICs") for medical applications such
as pacemakers and hearing aids.

Adjusted Net Income per common share                 1.01       0.67      0.84

Mitel's  total  revenue  grew  by  7%  from  Fiscal  1999.  By  business  group,
Semiconductor  revenue from continuing operations grew by 8% and Systems revenue
was up 5% from the  previous  year.  The  Semiconductor  growth  rate was mainly
attributable to sales of WAN Internetworking  products,  stimulated by increased
demand for high-speed  networking  systems.  Higher sales volumes of PBX systems
and telephone sets in North America and  alternative  network access products in
Europe drove the Systems revenue growth.

Adjusted Net Income excludes the impact of amortization of acquired intangibles,
special charges (net),  non-cash debt issue and other costs expensed on an early
partial debt repayment, and discontinued  operations.  Although not a substitute
for net income or net income per common share,  Adjusted Net Income and Adjusted
Net Income per common share are used by management as a supplementary measure to
assess financial performance.

<PAGE>

Net Income

Net income was higher in Fiscal 2000 than in Fiscal 1999 by $29.8,  or $0.26 per
share.  This  increase  was  primarily  due to revenue  growth and higher  gross
profits, principally in Semiconductor,  and to lower interest expense due to the
scheduled and mandatory debt  repayments made against the syndicated term loans.
Fiscal 1999's  results also included a $10.1 net charge to  rationalize  certain
Systems operations. The positive factors in Fiscal 2000 were partially offset by
higher  intangible  asset  amortization of $32.4 as a result of revisions to the
estimated useful lives of those assets made in the fourth quarter of Fiscal 1999
and to a higher  effective  income tax rate in Fiscal  2000  compared  to Fiscal
1999.

Adjusted Net Income

Adjusted  Net Income was higher in Fiscal 2000 than in Fiscal 1999 by $39.1,  or
$0.34 per share,  representing a year-over-year growth rate of 49%. The increase
in Adjusted Net Income primarily reflected  increases in Semiconductor  revenues
and gross margins,  partially  offset by a higher  effective  income tax rate in
Fiscal 2000 compared with Fiscal 1999.

Unless otherwise noted, the following  discussion pertains to Mitel's continuing
operations.

REVENUE

Business Segment Review

Mitel Communications Systems

(millions Cdn$)                                   2000       1999       1998

Systems revenue                                 $ 793.7    $ 752.7    $ 566.8
As a percent of total revenue                       57%        57%        64%

Systems  revenue grew by $41.0, or 5%, in Fiscal 2000 compared with Fiscal 1999.
The growth was due to  increased  sales  volumes of SX-200 and SX-2000  systems,
including  the  associated  pull-through  of  system  sets,  primarily  in North
America,  and to increased demand for Mitel's network access solutions  products
in Europe.  The improvement was partially  offset by lower European system sales
to  large  accounts  that  were  adversely  affected  in part by the  Year  2000
concerns.

Fiscal 2000 North American  channel sales  increased by 15% compared with Fiscal
1999. The U.S.  indirect  channel sales  benefited from increased  demand by the
small to  medium-sized  business  segment  for  Mitel's  SX-200 ML and SX-200 EL
switches.  U.S. direct channel sales benefited from increased  installations  of
new systems as well as from  upgrades in the existing  customer  base.  Based on
market  research  provided  by  Phillips  InfoTech,  a New  Jersey-based  market
research firm, Mitel's North American market share, based on PBX line shipments,
improved to 10.2% in calendar 1999 from 8.9% in calendar 1998. This placed Mitel
third overall in the North  American PBX line market.  Voice  messaging  product
sales were flat in this  region  compared  with last year as a result of delayed
orders,  partly due to Year 2000 concerns and a resulting  focus by customers on
core business systems instead of improved features and functionality.

The decline in European  system sales and service  revenue  compared with Fiscal
1999 was primarily the result of delayed orders in the latter half of the fiscal
year in light of the market's Year 2000 concerns and the lingering  effects into
the fourth quarter.  The lower sales were partially  offset by continued  higher
demand for Mitel's alternative network access products.


                                       40
<PAGE>

Systems sales into the Asia/Pacific  region were lower due to a reduced focus by
Mitel on competing in that region for enterprise communications systems.

Fiscal 2000 Systems segment  operating  income improved to $79.8, or by 30% over
Fiscal 1999,  primarily as a result of improved voice systems  margins and sales
channel efficiencies.

Fiscal 1999 Systems  revenue  growth of 33% compared with Fiscal 1998 was due to
increased  demand for  alternative  network access  products,  higher SX-200 and
SX-2000 sales through the U.S.  indirect channel,  and additional  revenues from
the advanced messaging and ISDN PBX businesses  acquired in the first quarter of
Fiscal 1999.

Mitel Semiconductor

(millions Cdn$)                                   2000       1999        1998
                                                ------------------------------

Semiconductor revenue                           $ 602.8     $ 557.7    $ 314.6
As a percent of total revenue                       43%         43%        36%

Through Fiscal 2000,  Mitel continued to consolidate and rationalize its product
line to focus on areas that  management  believes will result in high growth and
profitability.  Overall,  Semiconductor  revenue from  continuing  operations in
Fiscal 2000  increased by 8% from Fiscal 1999,  principally  due to stronger WAN
Internetworking  and  wireless  access  sales,  partially  offset by lower  home
gateway and medical sales. The significant increase in WAN internetworking sales
occurred  primarily in the United States.  The increase in wireless access sales
was driven by growth across all regions.  Management  believes that home gateway
and medical  sales will  improve in Fiscal 2001 based in part on a  strengthened
order backlog at year-end.

During Fiscal 2000, as part of a strategic plan to consolidate  capacity  levels
and  achieve  better  manufacturing  utilization,  Mitel  implemented  a plan to
transfer all semiconductor CMOS manufacturing operations from Jarfalla,  Sweden,
to Plymouth, U.K. The transfer resulted in improved semiconductor  manufacturing
capacity.  Since the transfer, the Swedish operation has been operating as an IC
fabless  facility  focused on the design,  marketing and sales of ASICs and as a
manufacturer and marketer of optoelectronic devices.

Certain  capital  investments  were made during Fiscal 2000 to increase  overall
semiconductor  production  capacity,  principally  for  wireless  and new  media
products, to meet the requirements of the growing semiconductor backlog.

Fiscal 2000 Semiconductor  segment operating income improved to $92.0, or by 70%
over Fiscal 1999, primarily as a result of an improved product portfolio mix and
higher manufacturing utilization.

Fiscal 1999 Semiconductor  revenue increased over Fiscal 1998 by 77% as a result
of  increased  demand  for the  Company's  ICs and thick film  hybrid  products,
primarily  in the U.S.,  and the  effects of  consolidating  the former  Plessey
Semiconductor Group for a full year.

Geographic Revenues

Revenue during the last three fiscal years, based on the geographic  location of
Mitel's customers, was distributed as follows:

                                                      -------------------------
United States                                         $ 632.7  $ 589.1  $ 404.1
Europe                                                  459.8    428.6    286.6
Asia/Pacific                                            159.9    166.7     92.8
Canada                                                   92.3     71.1     53.7
Other regions                                            51.8     54.9     44.2

For the year ended March 31,  2000,  the net  movement  in  exchange  rates from
Fiscal 1999 adversely affected total revenue by 3% ($45.6) primarily as a result
of changes in the U.K. pound sterling and U.S.  dollar  exchange  rates.  Fiscal
1999 revenue was favorably  affected by 4% ($54.1) as a result of changes in the
U.K. pound sterling and U.S. dollar exchange rates.

United States

Sales into the United  States  increased  by 7% in Fiscal 2000 over Fiscal 1999.
The  increase  was  principally  due to  higher  sales  of  SX-200  systems  and
associated  sets, and increased  installation of new systems and upgrades in the
existing  customer base.  Higher  Semiconductor  revenue also contributed to the
growth in this region,  primarily due to higher WAN Internetworking and wireless
sales.

Sales  increased  by 46% in the United  States in Fiscal 1999 over Fiscal  1998,
principally due to the Systems business.  Higher sales of SX-2000 and associated
sets,  and the  effects  of  consolidating  sales  resulting  from  the May 1998
acquisition  of  Centigram   Communications   Corporation's   Customer  Premises
Equipment, drove most of the increase.

Europe

European  sales  increased  by 7% in Fiscal  2000 over Fiscal 1999 due to higher
sales of  alternative  network  access  products to  long-distance  carriers and
stronger sales of semiconductors.

Fiscal 1999  revenue  into Europe  increased  by 49% over Fiscal 1998 due to the
effects of including a full year of the former Plessey group's results.

Canada

Canadian  sales  increased by 30% in Fiscal 2000 over Fiscal 1999 as a result of
increased  PBX market  share  driven by  stronger  sales of SX-200  and  SX-2000
systems  and higher  semiconductor  sales.  According  to  research  by Phillips
InfoTech,  Mitel was the number one PBX  supplier  in Canada in the under  1,000
line segment in calendar 1999,  capturing  34.2% of that market  segment.  Mitel
gained 8.7 market share points, up from 25.5% in calendar 1998.

The sales  increase  in Canada from Fiscal 1998 to Fiscal 1999 was 32% on higher
semiconductor  sales from the former  Plessey  operations and to higher sales of
SX-200 systems and sets in the Systems group.

Asia/Pacific

Asia/Pacific  sales  decreased by 4% in Fiscal 2000 compared to Fiscal 1999 as a
result of reduced focus on this segment of the enterprise communications systems
market.


                                       42
<PAGE>

Fiscal 1999 revenue in the Asia/Pacific region increased by 80%, principally due
to the effects of including a full year of the former Plessey group's results.

Other Regions

Sales into other  regions  decreased by 6% in Fiscal 2000  compared  with Fiscal
1999. The decrease was principally due to reduced semiconductor sales.

Fiscal  1999's  increase of 24% in sales into other regions over Fiscal 1998 was
due to the effects of consolidating Plessey for a full year.

GROSS MARGIN

(millions Cdn$)                                     2000      1999         1998
                                                  ------------------------------

Gross margin                                      $ 684.1    $ 598.0     $ 423.8
As a percent of revenue                               49%        46%         48%

The higher Fiscal 2000 gross margin was principally  attributable to a favorable
semiconductor  sales mix and positive  manufacturing  variances  resulting  from
improved semiconductor  manufacturing utilization and to the positive impacts of
higher sales volumes of voice systems and network access products.

Gross  margin in Fiscal 1999  decreased  relative to Fiscal 1998 by 2 percentage
points. The negative impact resulted mainly from increased amortization expense,
reduced  margins  in  some  products,  and  certain  unfavorable   manufacturing
variances in Semiconductor.

OPERATING EXPENSES

Selling and Administrative ("S&A")

(millions Cdn$)                                     2000      1999       1998
                                                  ----------------------------

S&A expenses                                      $ 359.4    $ 332.9   $ 246.0
As a percent of revenue                               26%        25%       28%

S&A expenses increased as a percentage of sales in Fiscal 2000 over the previous
year,  primarily due to Mitel's continued  investments in marketing new advanced
messaging  applications,  as well as  developing  new channels in Europe for the
ISDN PBX products.

Fiscal 1999 S&A expenses  decreased  as a percentage  of sales from Fiscal 1998,
primarily due to strong  revenue  growth and the inclusion of the former Plessey
operations,  where S&A expenses as a percentage of sales were lower than Mitel's
historical  average.  The  improvement  was  partially  offset by the effects of
consolidating the recently-acquired advanced messaging and ISDN PBX businesses.

Research and Development ("R&D")

(millions Cdn$)                                     2000      1999       1998
                                                  ----------------------------

R&D Expenses                                      $ 152.9    $ 149.8    $ 52.0

                                       43
<PAGE>

Fiscal 2000 R&D expenses  were net of $13.4 (1999 - $23.7;  1998 - $40.7) in R&D
government  assistance,  including  investment  tax  credits.  The R&D  focus in
Systems is directed to  introducing  new  Internet  Protocol-based  ("IP") voice
systems and peripherals for the enterprise  network and to integrating  advanced
messaging  applications  into its  product  portfolio.  R&D is also  ensuring  a
migration  path  for  Mitel  legacy  systems  to  the  new IP  architecture.  In
Semiconductor,  investments  are being  made in  high-growth  areas  such as WAN
Internetworking, optoelectronics and medical devices.

Special Charges (net)

During the fourth quarter of Fiscal 1999,  Mitel recorded a net pre-tax  special
charge of $10.1, including actions to rationalize certain aspects of the Systems
group,  net of a gain arising from the sale of certain non strategic  technology
and other assets.  The Systems  actions  reflected  efforts to streamline  North
American and European sales  channels by transfering  the network access product
manufacturing  operations  from North America to the United  Kingdom,  where the
majority of the sales are generated. Also included in the charge was the cost of
severance and related benefits,  with the majority of the reduction taking place
in the North American and Asia/Pacific  regions.  Approximately  100 people were
terminated as part of this rationalization program that was completed during the
year, resulting in a nil restructuring provision balance at March 31, 2000.

Amortization of Acquired Intangibles

Amortization  of  acquired  intangibles  increased  in Fiscal 2000 to $54.8 from
$22.4 in Fiscal 1999. In the fourth quarter of Fiscal 1999, the estimated useful
life of acquired intangibles was reduced to two years from an average of 5 to 15
years to better  reflect the estimated  period of advantage  achieved by Mitel's
recent  acquisitions,  and to be in line with evolving industry  practices.  The
revision to the estimated useful life of acquired intangibles  accounted for the
total increase.

INTEREST INCOME

Interest  income was $8.6 for the year ended March 31,  2000,  as compared  with
$5.9 in Fiscal 1999 and $5.7 in Fiscal 1998.  The increase  over Fiscal 1999 was
due to higher average cash balances on hand.

INTEREST EXPENSE

Interest  expense was $22.0 for Fiscal  2000,  compared  with $30.7 and $7.2 for
Fiscal 1999 and Fiscal 1998, respectively.  The decrease in interest expense was
principally  attributable to repayments on the syndicated term loans. The Fiscal
1999  increase  resulted  from the term loans  incurred by Mitel on February 12,
1998, in connection with the Plessey acquistion.

INCOME TAXES

Income tax expense for Fiscal 2000 was $39.6,  compared with $17.5 and $30.5 for
Fiscal 1999 and Fiscal 1998,  respectively.  The effective income tax rate, as a
percentage of pre-tax income from continuing operations and before the effect of
amortization  of  acquired  intangibles,  was 25%,  22% and 25% in Fiscal  2000,
Fiscal 1999 and Fiscal 1998,  respectively.  The increased effective tax rate in
Fiscal 2000 was mainly due to higher  taxable income in Canada and the favorable
impact in Fiscal 1999 of certain permanent differences  associated with European
operations. The Fiscal 1999 effective tax rate was lower than in Fiscal 1998 due
to lower taxes in Canada,  resulting  from higher  interest costs related to the
term loans and to tax recoveries in Europe.

BACKLOG

(millions Cdn$)                                     2000      1999       1998
                                                  ----------------------------

Backlog                                           $ 280.0    $ 179.8   $ 221.3

As orders are frequently booked and shipped within the same fiscal month,  order
backlog is not necessarily  indicative of a sales outlook for the month, quarter
or year.  This is most true for  Systems,  since  manufacturing  lead  times for
semiconductor  products  are  generally  longer  because  of the  nature  of the
production  process. At March 31, 2000, order backlog was $280.0, up from $179.8
at March 26, 1999.  The increase in backlog was  attributable  to higher  orders
arising from growing demand for  Semiconductor  products related to Internet and
broadband  connectivity.  Most of the backlog is  scheduled  for delivery in the
next 12 months.

Compared  with Fiscal  1998,  the  decrease in backlog of $41.5 from  continuing
operations  at the  end  of  Fiscal  1999  was  attributable  to a  decrease  in
semiconductor orders, arising partly from a reduction in order lead times.

LIQUIDITY AND CAPITAL RESOURCES

Mitel had cash, cash equivalents and short-term investment balances of $228.4 at
March 31, 2000,  compared  with $125.3 at March 26,  1999.  All of the March 31,
2000,  cash balance was held in either cash or highly  liquid cash  equivalents.
The  increase  of $103.1  was  mainly  due to cash flow  provided  by  operating
activities,  partially  offset by fixed asset additions and the cost of a common
share repurchase program.

Operating activities

Cash flow from  operations  before working  capital  changes  amounted to $229.3
during Fiscal 2000,  compared with $166.3 in Fiscal 1999.  Since March 26, 1999,
Mitel's working  capital,  as reflected in the  consolidated  statements of cash
flows,  decreased by $18.1,  primarily due to lower  receivables  as a result of
strong  collections  in the fourth quarter of Fiscal 2000,  partially  offset by
payments  made  against the  special  charges  and the  discontinued  operations
provisions.  Inventory  levels  remained  flat  compared  to  last  year.  Mitel
maintains a minimum of critical inventory to ensure continuity of supply for its
manufacturing requirements.  Most of the security supply inventory is carried at
Mitel's semiconductor plants.

Investing activities

Fixed asset and other  additions  were $60.9 during  Fiscal 2000,  compared with
$63.0 in the previous year,  excluding  additions of $25.2 and $22.7 financed by
capital  lease for the two  respective  periods.  The additions  were  primarily
related to continuing  improvements to Mitel's information technology resources,
as well as Semiconductor manufacturing capacity and technology enhancements.

The Fiscal 2000 technology  enhancements included the implementation of a global
ERP  software  system.  The project was  completed on schedule on April 1, 2000,
when the whole of the Company moved to the new ERP platform. Management believes
this advanced  information system will significantly  improve the business tools
supporting  sales  and  order  administration,  procurement,  manufacturing  and
financial reporting.  In addition,  the new system's  infrastructure enables the
Company to prepare for upcoming e-commerce and business-to-business initiatives.
The total project costs capitalized in Fiscal 2000, including hardware costs and
costs to configure the software, amounted to approximately $39.

In the fourth  quarter of Fiscal  2000,  Mitel  received  cash  proceeds of $9.5
related to the sale of the Lincoln business.

Financing activities

Mitel  has two  term  loans,  respectively  the  AXELsSM*  Series B loan and the
Tranche A Term  Loan,  that were  entered  into on  February  12,  1998,  with a
syndicate of banks led by Goldman, Sachs Credit Partners L.P. as the syndication
agent and the Canadian  Imperial Bank of Commerce as the  administrative  agent.
The term loans bear interest at a variable interest rate based on the lower of a
defined base rate or the London Inter Bank Offer Rate  ("LIBOR") plus a premium.
Mitel  entered  into an interest  rate swap to fix the base  interest  rate on a
portion of each of the term loans. The interest rate swap is considered to be an
effective  hedge of the  variable  interest  rates on the term  loans.  Mitel is
subject to certain  restrictive  covenants  and  commitments  and is required to
maintain  certain  financial  ratios for the purpose of ensuring  the  Company's
ability to meet its obligations under the credit  agreement.  The term loans are
subject to mandatory  prepayments  out of certain  insurance  proceeds,  defined
excess cash flow  generated by Mitel,  and the  proceeds of certain  asset sales
(other than inventory),  equity offerings or debt issuances by Mitel.  Mandatory
prepayments range from 50% to 100% of the applicable net cash proceeds and would
be paid on a pro-rata  basis  between the AXELs  Series Bond Tranche A Term Loan
subject  to certain  constraints  toward the  Tranche A Term  Loans.  Management
believes Mitel is in compliance with the  obligations and restrictive  covenants
under the credit agreement.

The  principal  of the AXELs  Series B loan is payable  in four equal  quarterly
installments  commencing  March 2003.  The  principal of the Tranche A Term Loan
will be fully repaid in June 2000 as a result of a mandatory prepayment required
to be made from Mitel's defined excess cash flow in Fiscal 2000.

Long-term  debt  decreased  due to  scheduled  repayments  of $10.0  against the
syndicated term loans.  As a result of the Lincoln sale,  Mitel made a mandatory
prepayment of $11.3 (U.S. $7.8) against the syndicated term loans on January 20,
2000.

On June 7, 1999,  Mitel  announced  its intention to make a normal course issuer
bid for up to 5,835,645  common shares (5% of  116,712,906  common shares issued
and outstanding at May 28, 1999).  These purchases took place on the open market
through the stock exchanges of Toronto and Montreal  commencing on June 9, 1999,
pursuant to the normal course issuer bid filed with these exchanges. As at March
31,  2000,  3,383,800  common  shares  were  purchased  and  canceled  for  cash
consideration of $36.4, including costs to acquire the shares.

As at March 31, 2000, Mitel's capitalization consisted of 30% debt, 4% preferred
equity and 66% common equity.  This compares with 32% debt, 4% preferred  equity
and 64% common equity at the end of Fiscal 1999.

In addition to cash and cash equivalent balances of $228.4 as at March 31, 2000,
Mitel  has  an  unused  revolving   credit  facility  of  approximately   $106.6
(U.S.$73.3).  In accordance with the terms of the credit agreement,  the maximum
amount of  U.S.$75.0  available  under the  revolving  credit  facility  will be
reduced by $13.0 (U.S.$8.9) in June 2000 as a result of the mandatory prepayment
triggered  by Mitel's  achievement  of defined  excess cash flow in Fiscal 2000.
Mandatory  prepayments that would exceed contractual  limitations on prepayments
of the  AXELs  Series B loan are  instead  applied  to  reduce  permanently  the
revolving loan commitments under the credit agreement.

Management believes Mitel is in a position to meet all foreseeable business cash
requirements and debt service from its cash balances on hand, existing financing
facilities and cash flow from operations.

YEAR 2000

The following statements  constitute a "Year 2000 readiness  disclosure" as that
term is  defined  in the Year 2000  Information  and  Readiness  Disclosure  Act
(P.L-105-271) signed into law by U.S. President Clinton on October 19, 1998.


                                       46
<PAGE>

The Year 2000 challenge was the result of computer  programs being written using
two digits rather than four digits to define the applicable  year. This practice
resulted in the possibility  that the Company's  internal  computer  systems and
products that have date-sensitive software could recognize a date that uses "00"
as 1900 rather than the year 2000. If Mitel's internal  computer systems misread
the year date,  system failures or  miscalculations  could cause  disruptions of
operations,  including  a  temporary  inability  to process  transactions,  send
invoices, or engage in similar normal business operations. A dedicated Year 2000
Program  Management  Office ("PMO") was  established in February 1998 to address
compliance both externally,  by Mitel's customers and suppliers, and internally,
with respect to Mitel's business  processes.  These internal  processes  include
network  and  communications  infrastructure,  business  software  applications,
manufacturing,  distribution, facilities management, product development, sales,
finance and human resources.

Mitel  experienced no major issues related to the transition to January 1, 2000.
Preparations  were made for the February 29, 2000 rollover to address  potential
problems  that would arise due to the  century  leap-year  date.  Though no Year
2000-related  issues were  encountered  over the  February  29,  2000  rollover,
internal systems will continue to be monitored for any unlikely disruptions. The
contingency  plans that were developed for use in the event of Year 2000-related
failures will be maintained and generalized for ongoing business use.

The Year 2000 PMO closed on March 31,  2000.  The final phase of Mitel's  formal
Year  2000  Program  was  the  collection   and  long-term   retention  of  Year
2000-related  due diligence  documentation.  Guidelines were developed to assist
Mitel in its standard  collection and retention of relevant  documentation  on a
worldwide  basis.  Due  diligence  will be  maintained  to ensure that  business
continues as usual.

As part of Mitel's Year 2000 Internal Readiness Program,  compliance of internal
systems was  addressed  by assessing  the  Company's  requirements  for business
continuation.  Through thorough inventory assessment,  testing and renovation of
internal information systems equipment,  Mitel safe-guarded its mission-critical
systems against major internal Year  2000-related  failures.  In addition,  risk
assessments were performed,  and contingency  plans were developed for technical
systems,  as well as for business  processes.  Year 2000  readiness  drills were
conducted at each corporate  location to further test and fine-tune  contingency
plans.

Mitel also  implemented  a Year 2000 Vendor  Management  Program and a Year 2000
Distributor   Management   Program,   which  required  that  all  suppliers  and
distributors  be evaluated and ranked upon  criticality  to the business.  Those
suppliers and  distributors  determined to be most critical to the business were
given highest  priority,  and  contingency  plans were  developed for use in the
event  that  critical  supplies  could  not be  delivered  to Mitel  or  regular
distribution channels were not available.

Mitel also  completed  comprehensive  tests on customer  premises  equipment and
semiconductor  component products manufactured and sold to customers,  including
current and certain discontinued  business telephone systems (PBXs),  peripheral
components and  applications.  The majority of these products were classified as
Year 2000-compliant or as having compliant versions.

The total  incremental  direct cost of the Year 2000 Internal  Readiness Program
amounted to $12.5 and was funded through operating cash flows. The program costs
were primarily attributable to the purchase of new software and equipment and do
not include estimates for potential litigation.

OTHER

Asia/Pacific Economic Risk

The  Asia/Pacific  region  encountered  unstable local economies and significant
devaluation  in its  currencies  during  Fiscal 1999 and through  most of Fiscal
2000. This region represented 11% of Mitel's revenue from continuing  operations
for the year ended March 31, 2000, and 13% of revenue from continuing operations
in


                                       47
<PAGE>

Fiscal 1999.  The  majority of the  Asia/Pacific  sales relate to  Semiconductor
operations.  Asia/Pacific receivables, net of reserves, were approximately 2% of
Mitel's total assets as at March 31, 2000.  To the extent that the  Asia/Pacific
region grows in  importance to Mitel,  or that the factors  affecting the region
begin to  adversely  affect  customers  in other  locations,  Mitel's  business,
operating results and financial condition could be adversely affected.

Foreign Currency Translation

Management periodically evaluates the financial and operational  independence of
its  foreign  operations  and the  resulting  accounting  classification  of the
foreign subsidiaries as self-sustaining enterprises. Should a foreign subsidiary
cease to be classified as  self-sustaining,  then translation gains or losses on
consolidating the foreign subsidiary's  financial statements would be charged to
operating  income instead of a separate  component of shareholders'  equity.  At
March  31,  2000,  the  translation  account  was in a debit  position  of $3.4,
representing  a decrease of $31.6 from the end of Fiscal 1999.  The decrease was
due  to a  stronger  Canadian  dollar  as  measured  against  other  currencies,
principally the U.K. pound sterling and the U.S. dollar.

European Union and the Euro

On January 1, 1999, 11 of 15 member countries of the European Union  established
fixed conversion rates between their existing currencies  ("legacy  currencies")
and one common  currency - the Euro.  The Euro will trade on currency  exchanges
and may be used in business transactions.  The conversion to the Euro eliminates
currency  exchange  rate risk between the member  countries.  Mitel's  operating
subsidiaries  that are affected by the Euro conversion have established plans to
address the issues raised by the Euro currency conversion.  These issues include
the need to  adapt  computer  and  financial  systems,  competitive  impacts  of
cross-border price transparency, and recalculating currency risk. Mitel does not
expect any required system  conversion  costs to be material due to the existing
ability to transact in multiple  currencies.  Due to significant  uncertainties,
Mitel cannot  reasonably  estimate the effects one common  currency will have on
pricing and the resulting impact, if any, on Mitel's financial  condition or its
results of operations.

Forward-Looking Statements

Certain  statements  in this  management's  discussion  and analysis  constitute
forward-looking  statements.  Such forward-looking  statements involve known and
unknown  risks,  uncertainties  and other  factors  that may  cause  the  actual
results,  performance  or  achievements  of Mitel,  or industry  results,  to be
materially  different  from any  future  results,  performance  or  achievements
expressed   or  implied  by  such   forward-looking   statements.   Such  risks,
uncertainties  and  assumptions  include the  following:  general  economic  and
business  conditions;  demographic  changes;  import  protection and regulation;
rapid technology development and changes;  timing of product introductions;  the
mix of  products/services;  industry  competition,  industry  capacity and other
industry trends; and the ability of Mitel to attract and retain key employees.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

MARKET RISK

Market  risk  represents  the risk of loss  that may  impact  Mitel's  financial
statements  due to adverse  changes in  financial  markets.  Mitel is exposed to
market risk from changes in interest rates and foreign exchange rates. To manage
these risks,  Mitel uses certain  derivative  financial  instruments,  including
interest rate swaps,  forward  contracts and other  derivative  instruments from
time to time, that have been authorized pursuant to board-


                                       48
<PAGE>

approved  policies  and  procedures.  Mitel  does not  hold or  issue  financial
instruments for trading or speculative purposes.

Mitel currently uses forward  contracts and foreign  currency  options to reduce
the exposure to foreign  exchange risk. The most  significant  foreign  exchange
exposures for Mitel relate to the U.S. dollar, U.K. pound sterling and the Euro.
At March 31, 2000, there were unrealized gains of $6.4 on the forward  contracts
and  unrealized  losses of $1.6 and $0.7 on the  forward  and option  contracts,
respectively. These unrealized gains and losses are calculated as the difference
between the actual  contract rates and the applicable  current market rates that
would be used if the foreign exchange  contracts were unwound on March 31, 2000.
Additional potential losses in the net fair value of these contracts, assuming a
10%  appreciation  in the U.S.  dollar against all currencies at March 31, 2000,
would have been approximately $9.0. Because these contracts are entered into for
hedging  purposes,  management  believes  that these  potential  losses would be
largely  offset by gains on the underlying  exposures  from firmly  committed or
anticipated transactions.

Interest  rate swaps are used to manage the impact of interest  rate  changes on
earnings and cash flows and also to lower overall borrowing costs.  Mitel's main
exposure to interest rate risk relates to its U.S. dollar  denominated long term
debt.  Mitel  monitors  its  interest  rate risk on the basis of changes in fair
value.  Assuming a 1 percentage  point rise in U.S.  interest rates at March 31,
2000, the potential loss in the net fair value of the interest rate swap and the
underlying  hedged debt would be $3.9 over the life of the debt.  Under the same
assumption,  the potential loss in the net change in fair value of unhedged debt
would  have  been  immaterial  because  substantially  all  of the  U.S.  dollar
denominated long-term debt is hedged.

In accordance  with Mitel policy,  cash  equivalent  and  short-term  investment
balances consist primarily of high-grade money market  instruments with original
maturity dates of less than one year.

The estimated  potential  losses discussed  previously  assume the occurrence of
certain  adverse  market  conditions.  These  calculations  do not  consider the
potential  effect of favorable  changes in market  factors and do not  represent
projected losses in fair value that Mitel expects to incur. Future impacts would
be based on actual developments in global financial markets. Management does not
foresee any  significant  changes in the strategies  used to manage interest and
foreign exchange rate risks in the near future.

retained  earnings and cash flows for each of the years in the three year period
ended March 31, 2000. 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 March 31, 2000
and March 26, 1999 and the results of its operations and its cash flows for each
of the years in the three year period  ended March 31, 2000 in  accordance  with

                                MITEL CORPORATION
                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

           (in millions of Canadian dollars, except per share amounts)

1.    NATURE OF OPERATIONS

      Mitel is an international  communications  product supplier. The Company's
      principal  business  segments comprise the manufacture and distribution of
      communications  systems  and  microelectronic  components.  The  principal
      markets for the Company's products are the United States,  Europe,  Canada
      and the Asia/Pacific region.

2.    ACCOUNTING POLICIES

      These consolidated  financial  statements have been prepared by management
      in accordance with accounting  principles  generally accepted in Canada. A
      reconciliation  of amounts  presented  in  accordance  with United  States
      accounting principles is detailed in note 23.

      The  preparation of financial  statements in conformity  with Canadian and
      United States accounting  principles requires management to make estimates
      and  assumptions  that  affect the  reported  assets and  liabilities  and
      disclosure  of  contingent  assets  and  liabilities  at the  date  of the
      financial  statements  and the  reported  amounts of revenue and  expenses
      during the  reporting  periods.  Actual  results  could  differ from those
      estimates.

(A)   FISCAL YEAR END

      The Company's  fiscal year end is the last Friday in March.  Normally this
      results in a fifty-two  week year with four  thirteen week  quarters.  For
      Fiscal 2000,  the year-end of the Company is March 31, 2000 resulting in a
      fifty-three week year.

(B)   BASIS OF CONSOLIDATION

      The consolidated  financial statements include the accounts of the Company
      and of its wholly-owned  subsidiary  companies.  Investments in associated
      companies, except for joint ventures, in which the Company has significant
      influence  are accounted for by the equity  method.  Investments  in joint
      ventures are accounted for by the proportionate consolidation method.

(C)   CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

      All highly liquid investments with original  maturities of three months or
      less are classified as cash and cash  equivalents.  The fair value of cash
      equivalents  approximates  the amounts shown in the financial  statements.
      Short-term  investments  comprise highly liquid low risk debt  instruments
      with terms of usually not greater  than one year.  Short-term  investments
      are carried at cost, which approximates their fair value.

(D)   INVENTORIES

      Inventories  are  valued at the lower of average  cost and net  realizable
      value for work-in-process and finished goods, and current replacement cost
      for raw materials.  The cost of inventories  includes material,  labor and
      manufacturing overhead.

(E)   CAPITAL AND OTHER ASSETS

      Capital assets are initially recorded at cost, net of related research and
      development  and  other  government  assistance.   Goodwill  is  initially
      recorded at the excess of the  Company's  cost over the amount of the fair
      value of the net identifiable  assets acquired in a business  combination.
      The Company  evaluates  the  realizability  of these assets based upon the
      expected future undiscounted cash flows of the related assets.


                                       55
<PAGE>

         Amortization is provided on the bases and at the rates set out below:

      Assets                                     Basis                  Rate
      --------------------------------------------------------------------------
      Buildings                                  Straight-line              4  %
      Equipment                                  Declining balance      20-30  %
                                                 Straight-line          10-33.3%
      Goodwill and other acquired intangibles    Straight-line             50  %
      Patents and trademarks                     Straight-line          10-33.3%

(F)   FOREIGN CURRENCY TRANSLATION

      The Company uses the current rate method of foreign  currency  translation
      to  translate  the  accounts of its foreign  subsidiaries.  The  resulting
      unrealized  gains or losses are  deferred  and  included in  shareholders'
      equity  until  there is a  reduction  in the net  investment  in a foreign
      operation.

      Exchange  gains or losses  related to  translation  of, or settlement  of,
      foreign  currency  denominated  long-term  monetary items are deferred and
      amortized on a straight-line basis over the remaining life of the items.

(G)   DERIVATIVE FINANCIAL INSTRUMENTS

      The Company enters into forward and option contracts intended to hedge its
      estimated net foreign currency cash requirements,  and certain significant
      transactions,  generally over the ensuing twelve to eighteen  months.  The
      Company does not engage in a trading or speculative  program.  All forward
      and option  contracts  are marked to market  and the  resulting  gains and
      losses  are  deferred  and  included  in the  measurement  of the  related
      transactions  when  they  occur.  Premiums  paid  with  respect  to option
      contracts  are  deferred  and charged to net  earnings  over the  contract
      period.

      The Company uses  interest  rate swap  contracts to manage  interest  rate
      risk.  Payments  and  receipts  under  interest  rate swap  contracts  are
      recognized as adjustments to interest expense on a basis that matches them
      with the related  fluctuations in the interest receipts and payments under
      floating rate financial assets and liabilities.

(H)   REVENUE RECOGNITION

      Revenue  from the sale of  products  is  recognized  at the time goods are
      shipped to  customers.  Revenue  from the sale of  communications  systems
      including  integration  and  installation  services,  is  recognized  on a
      percentage of completion basis.  Revenue from service is recognized at the
      time services are  rendered.  Billings in advance of services are included
      in  deferred  revenue.  Estimated  warranty  costs  associated  with these
      revenues are provided for at the time of the sale.

(I)   INCOME TAXES

      Income taxes are  accounted for using the deferred tax  allocation  method
      under which the income tax  provision  is based on the income  reported in
      the accounts.  Investment tax credits ("ITC") are taken into income on the
      same basis as the  related  expenditures  are charged to income or applied
      against acquired fixed assets, as applicable, provided the Company expects
      the credits to be realized. Management periodically reviews the reasonable
      assurance of realizing the ITC carryforward and timing difference benefits
      in the  determination  of their  accounting  recognition.  Such review may
      result  in the  recording  of the  accounting  benefit  for  these  timing
      differences and ITC carryforwards,  as the circumstances  warrant, and the
      recognition of loss carryforwards, as realized.

(J)   DEVELOPMENT COSTS

      The Company interprets the criteria for deferral of development costs on a
      very stringent basis under which few, if any, costs qualify for deferment.
      In the three years ended March 31, 2000,  all  development  costs,  except
      acquired intangibles purchased in a business combination, were expensed as
      incurred.  Management  periodically  evaluates  the  realizability  of the
      purchased  development  costs based upon the expected future  undiscounted
      cash flows of the related assets.


                                       56
<PAGE>

(K)   STOCK-BASED COMPENSATION PLAN

      The Company has a stock-based  compensation  plan described in note 14. No
      compensation  expense  is  recognized  for this plan  when  stock or stock
      options are issued to employees.  Any  consideration  paid by employees on
      exercise  of stock  options  or  purchase  of stock is  credited  to share
      capital.  If stock or stock options are repurchased  from  employees,  the
      excess of the consideration  paid over the carrying amount of the stock or
      stock option canceled is charged to retained earnings.

3.    SUPPLEMENTARY INCOME INFORMATION

      As a supplementary  measure to assess  financial  performance,  management
      utilizes  Adjusted  Net Income and  Adjusted  Net Income per common  share
      which exclude the impact of amortization of acquired intangibles,  special
      charges  (net),  non-cash debt issue and other costs  expensed on an early
      partial debt  repayment,  and  discontinued  operations.  The Adjusted Net
      Income and Adjusted Net Income per common share are as follows:

</TABLE>

      During  Fiscal 1998,  the Company  entered into a credit  agreement in the
      amount of U.S. $310.0 with Goldman Sachs Credit Partners L.P. ("GSCP"), as
      advisor,  arranger,  lender,  and  syndication  agent;  certain  financial
      institutions  as  lenders;  and the  Canadian  Imperial  Bank of  Commerce
      ("CIBC"),  as lender and administrative  agent for the lenders. The credit
      agreement provided senior secured credit facilities consisting of: (i) a 5
      year  Tranche  A  Term  Loan  amounting  to  U.S.$85.0;   (ii)  a  6  year
      Amortization  Extended  Term  Loan  (AXELs)  Series  B loan  amounting  to
      U.S.$150.0;  and (iii) a 5 year  revolving  credit  facility  amounting to
      U.S.$75.0  (see also note 25). The proceeds  from the term loans were used
      to fund the  acquisition  of 100% of the capital stock of four  affiliated
      entities  which,  together with their  respective  subsidiaries,  comprise
      Plessey (see also note 20).

      To secure the credit  agreement  obligations,  the Company  granted to the
      lenders  a  first  priority  lien  on  substantially  all of its  personal
      property  and certain of its real  property,  including a pledge of all of
      the  capital  stock  of  each  of  its  principal  subsidiaries.   Certain
      restrictive  covenants and financial  ratios required to be maintained are
      set out for the purpose of  measuring  the  Company's  ability to meet its
      obligations under the credit agreement.  The Company is subject to certain
      mandatory  prepayments in the event of asset sales (other than inventory),
      equity  offerings and debt  issuances,  certain  insurance  proceeds,  and
      defined excess cash flow. Mandatory  prepayments range from 50% to 100% of
      the net cash  proceeds  and would be paid on a prorata  basis  toward  the
      senior secured term loans.  The Company  believes it is in compliance with
      the obligations and restrictive covenants under the credit agreement.

      For the year ended March 31,  2000,  the Company had excess cash flow,  as
      defined by the credit  agreement,  that is  expected to result in the full
      repayment  of the  $27.0  Tranche  A term loan in June  2000.  No  further
      quarterly  principal  repayments  are  required on the AXELs Series B loan
      until March 2003, as per restrictions under the credit agreement.

      Future  minimum lease  payments of the  obligations  under capital  leases
      total $89.1 of which $34.9,  $29.3, $19.8, $4.2, and $0.9 relate to fiscal
      years 2001 to 2005 and  beyond  respectively.  Interest  costs of $8.4 are
      included in the total future lease payments.

      Scheduled  principal  repayments,   excluding  obligations  under  capital
      leases,  during the next five fiscal years are: 2001 - $27.0; 2002 - $1.4;
      2003 - $42.3; 2004 - $124.0; 2005 - $nil. Interest expense,  including the
      portion related to discontinued operations,  related to long-term debt was
      $25.9 in Fiscal 2000 (1999 - $37.7; 1998 - $7.6).

12.   COMMITMENTS

      (A)   OPERATING LEASES

            The future minimum lease payments for operating leases for which the
            Company was committed were as follows:  2001 - $21.8;  2002 - $16.0;
            2003 - $10.2; 2004 - $7.0; 2005 - $4.8; 2006 and beyond - $23.4.

            Rental expense on operating leases for the year ended March 31, 2000
            amounted to $25.0 (1999 - $24.7; 1998 - $17.1).

      (B)   LETTERS OF CREDIT

            The Company had letters of credit  outstanding  as at March 31, 2000
            of approximately $13.6 to collateralize duty charges.

      (C)   CAPITAL EXPENDITURES

            Capital expenditure commitments under purchase orders outstanding at
            the end of Fiscal 2000 amounted to approximately $9.4.

13.   CONTINGENCIES

      (a)   The  Company is a defendant  in a number of lawsuits  and party to a
            number of other claims or  potential  claims that have arisen in the
            normal course of its business. In the opinion of the Company's legal
            counsel, any monetary liability or financial impact of such lawsuits
            and claims or potential claims to which the Company might be subject
            after final  adjudication  would not be material to the consolidated
            financial position of the Company or the consolidated results of its
            operations.

      (b)   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 which 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.
            Although  the change in date has  occurred,  it is not  possible  to
            conclude that all aspects of the Year 2000 Issue that may affect the
            Company,  including those related to customer,  suppliers,  or other
            third  parties,  have been fully  resolved.  The effects of the Year
            2000 Issue may be  experienced  after  January  1, 2000,  and if not
            addressed,  the impact on  operations  and  financial  reporting may
            range from minor errors to significant  systems  failure which could
            affect an entity's ability to conduct normal business operations.

14.   CAPITAL STOCK

      The Company's  authorized capital stock consists of an unlimited number of
      preferred and common shares.

      Shares outstanding                               2000         1999
                                                     -------------------------

      Common shares                                  113,997,734   116,705,531


                                       60
<PAGE>

(A)   PREFERRED SHARES - R&D SERIES

      The preferred shares were issued in Fiscal 1984 for gross cash proceeds of
      $95.2 of which $51.5  ($23.00 per share) was  allocated  to capital  stock
      with the  balance  being the  consideration  received  for the sale of tax
      rights.

      Dividends - Fixed  cumulative  cash  dividends are payable  quarterly at a
      rate of $2.00 per share per annum.

      Redemption  - The shares are  currently  redeemable,  at the option of the
      Company, at $25.00 per share plus accrued dividends.

      Purchase Obligation - Commencing January 1, 1989, the Company was required
      to make  reasonable  efforts to purchase  22,400  shares in each  calendar
      quarter at a price not exceeding  $25.00 per share plus costs of purchase.
      The difference  between the stated capital of the repurchased  shares over
      the  consideration  paid for such shares is recorded  against  contributed
      surplus. During the year ended March 31, 2000, the Company purchased 8,400
      preferred shares for cash consideration of $0.2.

(B)   COMMON SHARES

      An analysis  of the changes in the number of common  shares and the amount
      of share capital for the three years ended March 31, 2000 is as follows:

                                                          Number       Amount

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

      Balance, March 27, 1998                           108,394,631      157.3

      Exercise of employee stock options                    310,900        1.9
                                                       -----------------------

      Balance, March 26, 1999                           116,705,531      331.2
      Repurchase of common shares                        (3,383,800)      (9.5)
      Exercise of employee stock options                    676,003        3.9
                                                       -----------------------

      Balance, March 31, 2000                           113,997,734    $ 325.6
                                                       =======================

      On June 7, 1999,  the Company  announced  its  intention  to make a normal
      course  issuer bid for up to 5,835,645  common  shares (5% of  116,712,906
      common shares issued and outstanding at May 28, 1999) between June 9, 1999
      and June 8, 2000. All  repurchased  shares will be cancelled.  As at March
      31, 2000,  3,383,800  shares have been  purchased and cancelled  under the
      normal course issuer bid for cash consideration of $36.4,  including costs
      to acquire  the  shares.  The amount  paid to acquire  the shares over and
      above the  average  carrying  value was  charged  pro rata to  contributed
      surplus  that arose  from  common  share  transactions,  with the  balance
      charged to retained earnings.

(C)   NET INCOME PER COMMON SHARE

      The net income per  common  share  figures  were  calculated  based on net
      income from continuing operations and net income, as applicable, after the
      deduction  of preferred  share  dividends  and using the weighted  monthly
      average number of shares  outstanding  during the respective fiscal years.
      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 year and the option issue date,
      and includes an allowance for imputed earnings net of tax derived from the
      investment of funds which would have been received.

(D)   DIVIDEND RESTRICTIONS ON COMMON SHARES

      The Company may not declare  cash  dividends on its common  shares  unless
      dividends on the  preferred  shares have been  declared  and paid,  or set
      aside for payment.


                                       61
<PAGE>

      Pursuant to the terms of the credit  agreement  described  in note 11, the
      Company is  restricted  from  declaring  any common share  dividends.  The
      preferred shares dividend has not violated this covenant.  No common share
      dividend is currently being paid out.

(E)   STOCK OPTION PLANS

      At the Company's 1991 Annual General Meeting,  the  shareholders  approved
      resolutions  authorizing  stock options for key employees and non-employee
      directors.   Certain   amendments   to  the  plan  were  approved  by  the
      shareholders at the 1993, 1995 and 1998 Annual General  Meetings  allowing
      for 1,000,000,  2,000,000 and 10,200,000 additional shares,  respectively,
      to be made available for grant. Available for grant at March 31, 2000 were
      6,691,248 (1999 - 10,465,525;  1998 - 243,525) shares. All options granted
      prior to  January  29,  1998  have  ten year  terms  and  options  granted
      thereafter  have six year terms.  All options become fully  exercisable at
      the end of four years of continuous employment.

      On July 12, 1999, the Company offered an option exchange program to option
      holders (with the exception of directors, officers and certain executives)
      who received  stock option  grants in calendar  1998 at $17.78 and higher.
      Under the terms of the  program,  and with the  consent of the Toronto and
      Montreal Stock Exchanges,  1,750,000  options were cancelled and 1,000,657
      new  options  were  granted at an exercise  price of $9.92 per share.  The
      reduction in number of options was directly  proportional  to the decrease
      in the exercise price. The new grants have a term of 6 years.

      A summary of the Company's stock option  activity and related  information
      for the three years ended March 31, 2000 is as follows:

16.   INVESTMENT TAX CREDITS AND GOVERNMENT ASSISTANCE

      During the year, the Company recognized Canadian ITCs and other funding of
      $14.0 (1999 - $23.7;  1998 - $40.7) related to eligible R&D  expenditures.
      Contributions  of $5.0  made to the  Company  in  prior  years  under  the
      Microelectronics  and System  Development  Program,  a federal  assistance
      program,  are  contingently  repayable  if  the  resulting  technology  is
      commercially  successful.  The  contributions  are  repayable  based  on a
      percentage  of  related  sales  over a period  not to exceed ten years and
      ending  on June 30,  2004.  Any  amount  unpaid at the end of the ten year
      period would be forgiven.  The total amounts repaid and repayable to March
      31, 2000 were negligible.

17.   SPECIAL CHARGES

      In Fiscal 1999, the Company recorded a net pre-tax special charge of $10.1
      related to the  rationalization of certain Company business segments,  net
      of a gain of $6.0 on the disposal of certain non-strategic  technology and
      other  assets.  The  rationalization  related to steps taken to streamline
      North  American and European sales  channels,  and to transfer the network
      access product  manufacturing  operations from North America to the United
      Kingdom,  where the majority of the sales are generated.  Also included in
      the  charge  was the cost of  severance  and  related  benefits,  with the
      majority  of  the  reduction  taking  place  in  the  North  American  and
      Asia/Pacific regions.  Approximately 100 people were terminated as part of
      this rationalization  program. The restructuring  programs related to this
      provision were completed during Fiscal 2000.

</TABLE>

      Deferred  taxes  on  income  generally  result  from  timing   differences
      primarily  in  the   recognition  of  tax  loss   carryforwards   and  R&D
      expenditures for tax and accounting purposes.

      The income tax  expense  reported  differs  from the  amount  computed  by
      applying the Canadian rates to the income before income taxes. The reasons
      for these differences and their tax effects were as follows:

      Unremitted  earnings of subsidiaries  subject to withholding taxes will be
      indefinitely   reinvested  with  no  provision   necessary  for  potential
      withholding taxes on repatriation of subsidiary earnings.  The loss before
      income  taxes  attributable  to all foreign  operations  was $15.7 (1999 -
      income of $5.0; 1998 - income of $7.4).

      As  at  March  31,  2000,  the  Company  had  tax  loss  carryforwards  of
      approximately  $154.0 for which an  accounting  benefit was  recognized on
      approximately   $64.5  of  these  tax  losses.   The  remaining  tax  loss
      carryforwards  are  available  to  reduce  future  years'  income  for tax
      purposes.  The tax loss  carryforwards for which an accounting benefit has
      been  recognized do not expire while the remaining tax loss  carryforwards
      expire as follows:  2004 - $5.5; 2005 - $13.6;  2006 to 2019 - $70.4.  The
      tax loss  carryforwards  relate to  operations in the United  States,  the
      United Kingdom,  Sweden and Germany. As at March 31, 2000, the Company had
      Canadian ITC carryforwards of approximately  $24.8, which are available to
      reduce future years' income taxes, for which the benefit was recognized in
      these financial  statements.  These ITCs expire during the years from 2007
      to 2010. In addition,  the Company had timing differences of approximately
      $60.0 for which no accounting benefit was recognized.

19.   DISCONTINUED OPERATIONS

      On March 26, 1999, the Company adopted formal plans to pursue  divestiture
      opportunities  related to the distinct operations of the Lincoln Power and
      Automotive  business  segment  ("Lincoln")  which was part of the  Plessey
      Semiconductors   Group  acquired  in  Fiscal  1998  (see  also  note  20).
      Accordingly, the operations related to this business were accounted for as
      discontinued operations.

      On January 19, 2000,  the Company  completed the sale of Lincoln for total
      consideration  of $12.0,  including cash of $9.5 and a note  receivable of
      $2.5. The financial results of the discontinued operations are as follows:

      The Lincoln  operating  loss of $9.8 for the ten months ended  January 20,
      2000 was charged to the provision for discontinued operations.

      The income (loss) before income taxes includes  allocated interest expense
      related to long-term debt of $nil,  $7.0 and $0.5 in Fiscal 2000, 1999 and
      1998,  respectively.   Interest  expense  was  allocated  to  discontinued
      operations based on a ratio of Lincoln revenue to total Plessey revenue.

      As at March 26,  1999,  total  net  assets  related  to  Lincoln  included
      inventories  of $18.2,  fixed assets of $13.6 and current  liabilities  of
      $14.3.

20.   ACQUISITIONS

(A)   On May 8,  1998,  the  Company  acquired  certain  assets of the  Customer
      Premises Equipment Business Unit of Centigram Communications  Corporation,
      now  operated  as the  Advanced  Messaging  business  unit  under the name
      Baypoint  Innovations,  for cash  consideration of U.S.$22.0.  The Company
      also purchased  receivables and  inventories  related to that business for
      approximately U.S.$4.8 in cash. The Advanced Messaging business,  based in
      San Jose,  California,  provides  productivity-enhancing,  enterprise-wide
      messaging  solutions  to  organizations  around the world  through a broad
      network of distributors  and agents.  The acquisition was accounted for by
      the purchase accounting method. The purchase price allocation was based on
      fair  values  assigned  to net  assets  as  determined  by an  independent
      valuation firm using standard valuation techniques. An amount of $35.9 was
      allocated to  identifiable  intangible  assets that include  completed and
      in-process  research and  development  and other  intangible  assets.  The
      difference  between  the  purchase  price  and the  fair  value of the net
      identifiable assets amounted to $0.6, which was recorded as goodwill.  The
      identifiable  intangible  assets and the goodwill are amortized over a two
      year period.  The allocation to net  identifiable  assets included $2.9 in
      respect of the acquisition  costs and costs to integrate the operations of
      the acquired  company.  As at March 31, 2000,  the liability in respect of
      acquisition and integration  costs was $nil (March 26, 1999 was $1.3). The
      purchase transaction was summarized as follows:

(B)   On May 19, 1998, the Company acquired the products,  technology,  research
      and  development  facilities  and  sales  and  marketing  organization  of
      Glasgow-based TSc for cash consideration of $8.0. TSc, now defined as ISDN
      PBX,  provides ISDN business  products for the small to medium  enterprise
      market.  The  acquisition  was  accounted  for by the  application  of the
      purchase  accounting  method  in which  the  results  of  operations  were
      included in the Company's accounts from the date of acquisition. An amount
      of $4.5 was  allocated  to  identifiable  intangible  assets  relating  to
      completed  research and development.  The difference  between the purchase
      price and the fair value of the net identifiable  assets amounted to $2.0,
      which was recorded as goodwill. The completed research and development and
      the goodwill are being amortized over a two year period. The allocation to
      net identifiable  assets included $2.0 in respect of the acquisition costs
      and costs to integrate the operations of the acquired company. As at March
      31, 2000 and March 26, 1999, the liability in respect of  acquisition  and
      integration  costs was $nil.  The purchase  transaction  was summarized as
      follows:

(C)   On  February  12,  1998,  the  Company  and  certain of its  wholly  owned
      subsidiaries  acquired  100%  of the  capital  stock  of  four  affiliated
      entities  which,  together with their  respective  subsidiaries,  comprise
      Plessey for a total cash consideration of $323.6 (U.S.  $225.0).  Plessey,
      headquartered  in  Swindon,   U.K.,  is  an  international   semiconductor
      manufacturer  for  communications  and media  applications.  The  acquired
      company operates as Mitel Semiconductor Limited in the U.K. and as part of
      Mitel Inc. in the U.S. The  acquisition  was accounted for by the purchase
      accounting method. The purchase transaction was summarized as follows:

      As at March 31, 2000,  the liability in respect of  acquisition  costs was
      $nil  (1999 - $nil) and $nil  (1999 - $10.6)  in  respect  of  integration
      costs.  The integration  costs primarily  related to initial  estimates to
      exit the Lincoln Power and Automotive  business  segment,  the transfer of
      redundant  production  activities  from Sweden to Plymouth,  U.K.,  and to
      severance  costs for  redundancies in the acquired  semiconductor  segment
      throughout the world. The remaining integration  activities were completed
      during Fiscal 2000.

(D)   On August 8, 1997,  the  Company  acquired  certain  assets and the remote
      access  business  of  Gandalf   Technologies   Inc.   (Gandalf)  for  cash
      consideration of $21.6. The purchase  agreement did not include  Gandalf's
      service   business.   Gandalf's  remote  access  products  and  technology
      facilitate high volume data and voice communications between the corporate
      office, local branches,  teleworkers,  and agents in the field.  Gandalf's
      operations  are based  principally in Canada,  the United States,  and the
      United  Kingdom.  In  addition  to the  cash  consideration,  the  Company
      incurred  expenses  of $0.5 in  respect of  acquisition  costs and $0.6 in
      respect of costs to integrate the operations of the acquired company.  The
      integration program was completed during Fiscal 1999.

      This acquisition was accounted for by the purchase  accounting method. The
      purchase price  allocation was based on fair values assigned to net assets
      as determined by an independent  valuation  firm using standard  valuation
      techniques.  An amount of $14.9 was allocated to  identifiable  intangible
      assets which include  completed and in-process  research and  development,
      trademarks,  and the tradename. The purchase transaction was summarized as
      follows:

      Net assets acquired, at approximate fair value:

      Current assets                                               $  7.1

21.   RELATED PARTY TRANSACTIONS

      During the year ended March 31, 2000,  the Company  sold to and  purchased
      from jointly controlled and significantly  influenced enterprises products
      and services valued at  approximately  $2.7 (1999 - $3.8; 1998 - $2.5) and
      $0.9 (1999 - $1.0; 1998 - $nil) respectively.

22.   INFORMATION ON BUSINESS SEGMENTS

      Reportable  segments,   known  as  "business  segments",  are  defined  as
      components of an enterprise about which separate financial  information is
      available and is used regularly by the chief operating  decision makers to
      evaluate the segment's  performance  and assess future cash flow.  Mitel's
      chief decision  making group  includes the Chief  Executive  Officer,  the
      Board  of  Directors  and  certain  executives  in each  of the  operating
      segments at Mitel.

      Reportable  segments are business units that offer different  products and
      services  that  are  managed   separately   because  of  their   different
      manufacturing  and  distribution   processes.   The  Company's  reportable
      business  segments include the Mitel  Communications  Systems  ("Systems")
      group and the Mitel Semiconductor ("Semiconductor") group.

      Mitel  Communications  Systems  provides  enterprises  with voice and data
      communications  systems;  complete  private  networks,   including  remote
      teleworking solutions; unified messaging and call-center applications; CTI
      systems and applications;  and it also supplies  competitive carriers with
      public network access products.  All of Mitel's service revenue relates to
      Systems.

      Mitel Semiconductor provides connectivity solutions for the communications
      and medical industries with a product range which includes  components for
      both  wired and  wireless  networks;  microelectronics  for  enabling  the
      convergence  of voice  and data;  optoelectronic  devices  for  high-speed
      Internet systems;  and, also,  applications-specific  integrated  circuits
      ("ASICs") for medical applications such as pacemakers and hearing-aids.

      The Company  evaluates the  performance  and allocates  resources based on
      operating   income  from   continuing   operations,   which  excludes  any
      intersegment  sales of  products  and  services.  Mitel does not  allocate
      amortization of intangibles, special charges, interest revenue or interest
      expense and income taxes to its reportable  segments.  In addition,  total
      assets are not allocated to each segment; however, depreciation of capital
      assets  is  allocated  to the  segments  based  on the  asset  usage.  The
      accounting  policies  of the  reportable  segments  are the  same as those
      described in the summary of significant accounting policies.

      Major Customers

      No single customer  accounted for 10% or more of the Company's revenue for
      the last three fiscal years. In addition,  the Company is not dependent on
      any single customer or group of customers, or suppliers.

23.   UNITED STATES ACCOUNTING PRINCIPLES

      The  consolidated  financial  statements  have been prepared in accordance
      with accounting  principles  generally  accepted in Canada (Canadian GAAP)
      which, in the case of the Company,  conform in all material  respects with
      those in the United States (U.S.  GAAP) and with the  requirements  of the
      Securities and Exchange Commission (SEC), except as follows:

      (A)   Under Canadian GAAP, investments in joint ventures are recognized in
            the   financial   statements   of  the   venturer  by  applying  the
            proportionate  consolidation method of accounting.  Under U.S. GAAP,
            equity  accounting is applied to  investments in joint ventures when
            preparing the consolidated financial statements of the venturer.

      (B)   Purchased R&D under Canadian GAAP is capitalized  and amortized over
            the  remaining  useful life of the  technology  to which it relates.
            Under U.S.  GAAP,  the purchased  in-process  R&D is expensed at the
            time of  acquisition.  The Company has not established the technical
            feasibility of the  in-process R&D and it has no alternative  future
            use.

      (C)   Under  Canadian  GAAP,  unrealized  and realized gains and losses on
            foreign currency  transactions  identified as hedges may be deferred
            as long as there is  reasonable  assurance  that the  hedge  will be
            effective.  Under U.S.  GAAP,  deferral  is allowed  only on foreign
            currency  transactions  intended to hedge  identifiable firm foreign
            currency commitments.

      (D)   Under Canadian GAAP, exchange gains or losses related to translation
            of  foreign  currency  denominated   long-term  monetary  items  are
            deferred and amortized over the remaining  life of the items.  Under
            U.S.  GAAP,  deferral  is not  allowed  and such gains or losses are
            included in the determination of net income.

      (E)   The Company  implemented  SFAS 109,  Accounting for Income Taxes, in
            Fiscal 1994 for purposes of reconciliation to U.S. GAAP. As at March
            31, 2000, the Company's deferred tax asset, primarily related to the
            benefit of realizing  investment tax credit,  loss carryforwards and
            temporary differences, net of a valuation allowance of $78.0 (1999 -
            $80.0),  was $15.7 (1999 - $29.3),  and  deferred  tax  liabilities,
            primarily   related  to  research  and   development   expenditures,
            buildings and equipment,  were $9.8 (1999 - $23.2).  The application
            of this method also gives rise to  differences  in the allocation of
            consideration with


                                       69
<PAGE>

            respect to business combinations which may result in the recognition
            of deferred tax balances. Subsequent realization of any unrecognized
            tax  benefits  will be applied to reduce any  remaining  goodwill or
            intangibles  of the related  acquisitions,  before being reported in
            net income for U.S. GAAP purposes.

      (F)   Under  Canadian  GAAP,  certain costs related to the acquirer may be
            recognized in the purchase  price  allocation  when  accounting  for
            business  combinations.  These costs, subject to certain conditions,
            qualify  where  they are a direct  substitute  for costs  that would
            otherwise be incurred with respect to the acquired  business.  Under
            U.S. GAAP, only costs relating directly to the acquired business may
            be considered in the purchase price allocation. This has resulted in
            a  difference  in the  valuation  of  goodwill  at the  time  of the
            purchase and in the subsequent amortization of the goodwill.

      (G)   Under U.S. GAAP the fully diluted  earnings per share is computed in
            accordance  with the treasury stock method and based on the weighted
            average   number  of  common   shares  and  dilutive   common  share
            equivalents.

      (H)   U.S. GAAP requires the  presentation of  comprehensive  income which
            includes all changes in shareholders'  equity during a period except
            shareholders  transactions.  In  addition,  items  defined  as other
            comprehensive   income   such  as   foreign   currency   translation
            adjustments,  are separately  classified in the financial statements
            and the accumulated balance of other comprehensive  income (loss) is
            reported separately in shareholders' equity on the balance sheet.

      (I)   Redeemable  preferred shares are excluded from shareholders'  equity
            under requirements of the SEC.

      (J)   Under Canadian GAAP, stock issue costs may be shown as an adjustment
            to retained earnings.  The carrying amount of capital stock is shown
            net of issue costs under U.S. GAAP.

      (K)   Reductions in stated capital and deficit are not recorded under U.S.
            GAAP.  The  Company had  previously  undertaken  stated  capital and
            deficit reductions in fiscal years 1985, 1986, 1987 and 1992.

      (L)   As allowed under SFAS 123, Accounting for Stock-Based  Compensation,
            management has determined that it will continue to apply  Accounting
            Principles  Board  Opinion  No. 25 (APB 25), in  accounting  for its
            employee stock options for purposes of  reconciliation  to U.S. GAAP
            because the  alternative  fair value  accounting  provided for under
            SFAS 123 requires the use of option  valuation  models that were not
            developed for use in valuing  employee stock options.  In accordance
            with Company  policy,  the exercise price of the Company's  employee
            stock options equals the market price of the underlying stock on the
            date of grant.  Accordingly  under  the rules of APB 25, no  related
            compensation  expense  was  recorded  in the  Company's  results  of
            operations for U.S. GAAP purposes.

      (M)   The Financial  Accounting  Standards  Board has issued  Statement of
            Financial  Accounting  Standards No. 133, "Accounting for Derivative
            Instruments  and  Hedging  Activities"  ("SFAS  133")  which will be
            effective for the Company's March 29, 2002 year end. The Company has
            not  determined  the impact,  if any, of this  pronouncement  on its
            consolidated financial statements.

      (N)   The Financial  Accounting  Standards  Board ("FASB") has issued FASB
            Interpretation  No. 44 of APB Opinion No. 25, Accounting for certain
            transactions  involving stock  compensation  which will be effective
            for the  Company's  March 30, 2001 year end.  The  Company  does not
            anticipate this  interpretation will have any material impact on its
            consolidated financial statements.

      The  following  table  reconciles  the  net  income  as  reported  on  the
      consolidated  statements  of income to the net income that would have been
      reported had the financial  statements  been  prepared in accordance  with
      U.S. GAAP and the requirements of the SEC. The proportionate consolidation
      method for joint  ventures  does not affect the  measurement  of income or
      shareholders'  equity and  therefore  is not  addressed  in the  following
      table:

The following  options were excluded in the computation of diluted  earnings per
share from continuing  operations  because the options'  exercise price exceeded
the average market price of the common shares and,  therefore,  the effect would
be  antidilutive:  options  outstanding  for the year  ended  March 31,  2000 to
purchase  3,424,622 (1999 - 3,142,250;  1998 - 3,167,250) shares of common stock

      The  Black-Scholes  option  valuation  model  was  developed  for  use  in
      estimating  the  fair  value  of  traded  options  which  have no  vesting
      restrictions  and are fully  transferable.  In addition,  option valuation
      models require the input of highly  subjective  assumptions  including the
      expected  stock price  volatility.  Because the Company's  employee  stock
      options have characteristics  significantly different from those of traded
      options,  and because  changes in the  subjective  input  assumptions  can
      materially affect the fair value estimate,  in management's  opinion,  the
      existing  models do not  necessarily  provide a reliable single measure of
      the fair value of its employee stock options.

      For purposes of Pro Forma  disclosures,  the  estimated  fair value of the
      options is  amortized to expense  over the  options'  vesting  period on a
      straight-line basis (see also note 14).

24.   PENSION PLANS

      The Company  maintains  several  defined  contribution  and three  defined
      benefit  pension plans for its  employees.  The  components of the pension
      expense are as follows:

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

      (A)   Defined Contribution Pension Plans

            Both the Company and the  employees  contribute to these plans based
            on the employees' earnings.


                                       72

      (B)   Defined Benefit Pension Plans

            The  Company's  policy is to fund defined  benefit  pension plans in
            accordance with independent actuarial valuations and as permitted by
            pension regulatory authorities.

            There  are  two  contributory   defined  benefit  plans  that  cover
            substantially  all  employees  of Mitel  Telecom  Limited  and Mitel
            Semiconductor  Limited ("MSL"), two wholly owned subsidiaries of the
            Company.  These plans provide  pension  benefits  based on length of
            service and final pensionable earnings.  Employee  contributions are
            based on pensionable earnings.  Actuarial reports in connection with
            these defined  benefit plans,  updated to March 31, 2000, were based
            on  projections  of  employees'  compensation  levels to the time of
            retirement.

            For  purposes of an  actuarial  valuation,  pension fund assets were
            valued using the discounted income method. Under this approach,  the
            value of the assets is obtained by  estimating  the  receipts  which
            will  arise in the  future  from  the  plan's  investments  and then
            discounting the amounts to the valuation date, at the valuation rate
            of return on assets.

            The third defined  benefit plan covers all employees over the age of
            twenty-eight in Sweden and provides pension benefits based on length
            of service and final pensionable earnings. There are no pension fund
            assets  under  the  plan.  The  associated   pension   liability  is
            calculated  each year by the Pension  Registration  Institute and is
            insured in its entirety by Forsakringsbolaget Pensionsagaranti.  The
            pension  liability of $13.0 (76.9 SEK) (1999 - $13.2 (72.7 SEK)) was
            actuarially  determined  based on the  present  value of the accrued
            future pension  benefits and in accordance  with applicable laws and
            regulations in Sweden.

      The following table shows the plans' funded status reconciled with amounts
      reported in the consolidated  balance sheets,  and the assumptions used in
      determining the actuarial present value of the benefit obligations:

25.   FINANCIAL INSTRUMENTS

(A) Fair value

      The Company's  financial  instruments  include cash and cash  equivalents,
      short-term  investments,   accounts  receivable,   long-term  receivables,
      accounts payable, long-term debt, interest rate swaps and foreign exchange
      contracts.  Due to the short-term  maturity of cash and cash  equivalents,
      short-term  investments and accounts payable, the carrying values of these
      instruments are reasonable  estimates of their fair value.  The fair value
      of  long-term  debt was  determined  by  discounting  future  payments  of
      interest and principal at estimated interest rates that would be available
      to the  Company  at  year-end.  The  fair  value of the  foreign  exchange
      contracts  reflects the estimated  amount that the Company would have been
      required to pay if forced to settle all outstanding contracts at year-end.
      This  fair  value  represents  a  point-in-time  estimate  that may not be
      relevant in predicting the Company's  future  earnings or cash flows.  The
      fair value of financial instruments  approximate their carrying value with
      the following exceptions:

(B) Derivative financial instruments

      The Company  operates  globally,  and therefore may  experience  risk that
      earnings  and cash flows may be  adversely  impacted  by  fluctuations  in
      foreign exchange.  The Company uses forward and option contracts to manage
      foreign  exchange  risk.  Generally,  forward  and  option  contracts  are
      designated for firmly committed or forecasted sales and purchases that are
      expected to occur in less than one year.  At March 31,  2000,  the Company
      owned four Canadian dollar call option  contracts  outstanding for a total
      notional  value of $40.0 U.S.  dollars  (1999 - $nil) and with  maturities
      ranging from July to October, 2000. The total premium paid for the options
      was $1.2 and is deferred and amortized  over the life of the options.  The
      fair value of the options at March 31, 2000, was $0.5.

      The  notional  amounts for forward  contracts  represent  the U.S.  dollar
      equivalent of an amount  exchanged.  Most of the forward  contracts mature
      within six months with the longest maturity  extending to February,  2001.
      At March 31, 2000,  deferred gains totaled $6.4 (1999 - $3.4) and deferred
      losses  totaled $1.6 (1999 - $3.6).  The following  table presents the net
      notional amounts of the forward contracts in U.S. dollars:

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

      On March 12, 1998,  the Company  entered into an interest rate swap to fix
      the  interest  on a portion of the AXELs  Series B loan and the  Tranche A
      Term Loan for a notional  amount of $224.5 (U.S.  $157.0).  Since then, it
      has been reduced to $189.0 (U.S. $130.0), which is sufficient to cover the
      total  outstanding  balance of the two term loans.  The base interest rate
      was fixed at 5.79% and the contract  matures on March 2001.  This interest
      rate swap is considered to be an effective hedge of the variable  interest
      rate on the term loans. The Company is exposed to credit risk in the event
      of  non-performance,  but  does  not  anticipate  non-performance  by  the
      counterparty.

(C) Credit risk

      The  Company's  financial  assets that are exposed to credit risk  consist
      primarily of cash and cash equivalents,  short-term investments,  accounts
      receivable  and  derivative  contracts.  Cash  and  cash  equivalents  and
      short-term  investments  are invested in government and  commercial  paper
      with investment grade credit rating.

      The Company is exposed to normal credit risk from customers.  However, the
      Company's  orientation is global with a large number of diverse  customers
      to minimize concentrations of credit risk.

      Mitel is exposed  to credit  risk in the event of  non-performance  by its
      counterparties  on its foreign exchange  contracts and interest rate swap.
      The  Company  does  not   anticipate   non-performance,   by  any  of  the
      counterparties,  as it deals with  counterparties  who are major financial
      institutions.  The Company  anticipates  the  counterparties  will satisfy
      their obligations under the contracts.

(D) Interest rate risk

      The Company is not exposed to  significant  interest  rate risk due to the
      short-term maturity of its monetary assets and current liabilities.

(E) Unused bank lines of credit

      The  Company has a line of credit for $109.0  (U.S.$75.0),  of which up to
      $29.1  (U.S.$20.0) is available for letters of credit.  At March 31, 2000,
      $2.4  (U.S.$1.7)  (1999 - $2.3) in  letters  of  credit  were  outstanding
      against this credit  facility,  thus the Company had unused and  available
      demand bank lines of credit amounting to approximately  $106.6 (U.S.$73.3)
      (1999 - $110.7) at a rate of interest based on a defined US base rate plus
      0.75% or a successive three month LIBOR plus 1.75%. In June 2000, the line
      of credit is expected  to be reduced by $13.0  (U.S.  $8.9) as a result of
      excess cashflow at March 31, 2000, as defined by the credit agreement (see
      also note 11), and Mitel  reaching its limit for mandatory  prepayments on
      its AXELs Series B loan.

STATEMENT OF CORPORATE GOVERNANCE PRACTICES

General

      In February  1995,  The Toronto  Stock  Exchange  Committee  on  Corporate
Governance in Canada  issued its final report  containing a series of guidelines
for effective  corporate  governance (these guidelines,  as amended from time to
time, are herein referred to as the "Governance Guidelines").  These guidelines,
which are not mandatory,  deal with the  constitution of boards of directors and
board  committees,  their functions,  the  effectiveness  and education of board
members, their independence from management,  their relationship with management
and  shareholders  and other means of ensuring sound corporate  governance.  The
Toronto Stock Exchange has, in accordance with the recommendations  contained in
such report,  adopted as a listing  requirement  that disclosure be made by each
listed  company  of  its  corporate  governance  system  with  reference  to the
Governance Guidelines.

      In 1999, The Toronto Stock Exchange amended the Governance  Guidelines and
companies are now required to disclose their corporate governance practices with
specific reference to each of the 14 Governance Guidelines.

      The Board of Directors  and the members of the  Company's  management  are
committed  to the  highest  standard  of  corporate  governance.  The  Company's
corporate  governance  practices  comply  with the  Governance  Guidelines.  The
Company's principal objective in directing and managing its business and affairs
is to enhance  shareholder value. The Company believes that effective  corporate
governance improves corporate performance and benefits all Shareholders.

      The Board of  Directors  of the Company has always  endorsed  the concept,
principles  and practices of sound  corporate  governance  and believes that the
Company is in substantial compliance with the Governance Guidelines.

      The following is a summary of the  particulars  of the system of corporate
governance of the Company.

Mandate of the Board

      The Board of Directors  establishes  the overall  policies for the Company
and monitors and evaluates the Company's strategic direction and retains plenary
power  for those  functions  not  specifically  delegated  by it to  management.
Accordingly,  the  mandate  of  the  Board  of  Directors  is to  supervise  the
management  of the  business and affairs of the Company with a view to evaluate,
on an ongoing  basis,  whether the  Company's  resources  are being managed in a
manner consistent with enhancing  Shareholder value, ethical  considerations and
corporate  social  responsibility.  In order to better fulfill its mandate,  the
Board of Directors has formally acknowledged its responsibility for, among other
matters:

      (i)   reviewing and  approving,  at the beginning of each fiscal year, the
            business plan,  capital budget and financial goals of the Company as
            well as longer term  strategic  plans  prepared  and  elaborated  by
            management and,  throughout the year,  monitoring the achievement of
            the objectives set;

      (ii)  ensuring that it is properly  informed,  on a timely  basis,  of all
            important  issues  (including  environmental,  cash  management  and
            business development issues) and developments  involving the Company
            and its business environment;

      (iii) identifying,  with management,  the principal risks of the Company's
            business  and the systems put in place to manage these risks as well
            as monitoring, on a regular basis, the adequacy of such systems;


                                       79
<PAGE>

      (iv)  ensuring proper succession planning, including appointing,  training
            and monitoring senior executives;

      (v)   assessing performance of senior executives;

      (vi)  ensuring  proper  communication  with  Shareholders,  customers  and
            governments; and

      (vii) monitoring  the  efficiency  of  internal   control  and  management
            information systems,

and has taken, when necessary, specific measures in this respect.

      Long term goals and  strategies  for the Company are  developed as part of
its annual strategic  planning  process with the Board of Directors,  which also
includes the preparation of a detailed  one-year  operating  plan.  Through this
process,  led by the President and Chief Executive Officer and senior management
of the Company,  the Board of Directors adopts the operating plan for the coming
financial year and monitors  senior  management's  relative  progress  through a
regular  reporting  and  review  process.  The Board of  Directors  reviews on a
quarterly  basis the  extent to which the  Company  has met the  current  year's
operating plan.

      To comply with the Governance  Guidelines  which recommend that a board of
directors  should  assume  responsibility  for  succession  planning,  including
appointing,  training and monitoring senior  management,  the Board of Directors
reviews all appointments of officers.

      The Board of  Directors  has put  policies  in place to ensure  effective,
timely and non-selective  communications  between the Company,  its stakeholders
and the public.  The Board, or the appropriate  committee  thereof,  reviews the
content of the Company's major  communications to Shareholders and the investing
public,  including  the  quarterly  and annual  reports,  and approves the proxy
circular,  the annual  information form and any prospectuses that may be issued.
The disclosed  information is released through  mailings to  Shareholders,  news
wire services, the general media and a home page on the internet.

      The  Company has an investor  relations  group which  responds to analyst,
institutional  and  individual  Shareholder  inquiries and maintains a toll-free
telephone line for ease of contact.  Individual queries, comments or suggestions
can be  made  at any  time by  calling  or  writing  directly  to the  Company's
registered office in Kanata,  Ontario,  Canada.  In addition,  the Company has a
communications  group to respond to  inquiries  from media,  government  and the
public.  Together,  these groups deal with stakeholder  concerns and ensure that
all inquiries receive a full and timely response.

Composition of the Board and of its Committees

      The  Governance   Guidelines  recommend  that  a  board  of  directors  be
constituted of a majority of individuals  who qualify as "unrelated  directors".
The Governance  Guidelines  define an "unrelated  director" as a director who is
independent  of  management  and is free from any  interest  and any business or
other  relationship which could, or could reasonably be perceived to, materially
interfere with the  director's  ability to act with a view to the best interests
of  the  Company,   other  than   interests  and   relationships   arising  from
shareholding.  The  Governance  Guidelines  also  make an  informal  distinction
between "inside" and "outside" directors.  The Governance Guidelines and related
rules  consider an inside  director of a corporation  to be a director who is an
officer or employee of the corporation or any of its subsidiaries.

      The directors of the Company have examined the relevant definitions of the
Governance   Guidelines  and  have  individually   considered  their  respective
interests in and relationships with the Company. As a consequence,  the Board of
Directors has determined that on a rigorous application of these definitions, it
would be composed of eight  unrelated  directors  out of eleven  board  members.

Officer,  Kirk K. Mandy,  President and Chief Executive  Officer,  and Donald G.

Senior Vice  President,  Human  Resources,  General  Counsel and  Secretary  are
considered to be related to the Company.

      The Governance  Guidelines also recommend that a board of directors should
examine  its size.  The Board of  Directors  believes  that the number of eleven
directors will be sufficient and  appropriate to effectively  conduct  business.
The Board of  Directors,  as  presently  constituted,  brings  together a mix of
skills,  backgrounds  and  individual  attributes  that the  Board of  Directors
considers appropriate to the stewardship of the Company.

      The Governance  Guidelines also recommend that, in  circumstances  where a
corporation  has a "significant  shareholder"  (that is, a shareholder  with the
ability to exercise the majority of the votes for the election of the  directors
of a corporation),  the Board of Directors  should include a number of directors
who do not have interests in or relationships with either the corporation or the
significant  shareholder  and  should  fairly  reflect  the  investment  in  the
corporation by shareholders other than the significant shareholder.  The Company
does not presently have a significant shareholder.

      A further Governance Guideline recommends that the Audit Committee be made
up of outside and unrelated  directors  only.  This  guideline  also states that
other board committees should be comprised of outside  directors,  a majority of
whom should be unrelated  directors.  The Company currently has four committees,
being the Audit Committee,  the Compensation Committee, the Nominating Committee
and the Executive Committee. All of these committees,  as presently constituted,
comply with the Governance Guideline recommendations. It is the intention of the
Board of  Directors  to  reevaluate  from  time to time the  composition  of the
various committees.

      The four committees of the Board of Directors have been  established  with
specific  mandates  and defined  authorities  with a view to assist the Board of
Directors in efficiently carrying out its  responsibilities.  Set out below is a
general  description  of  the  committees  of the  Board  and  their  respective
mandates.

Audit Committee

      The Company has a standing  Audit  Committee.  Information  regarding  the
functions  performed by the Audit Committee,  its membership,  and the number of
meetings  held during the fiscal year,  is set forth in the "Report to the Audit
Committee," included in this Form 10-K.

      The Audit  Committee is presently  composed of three outside and unrelated
directors: Donald W. Paterson, Peter van Cuylenburg and Hubert T. Lacroix.

Compensation Committee

      The mandate of the Compensation  Committee is outlined above under "Report
on  Executive  Compensation".  This  mandate  further  includes  a review of the
compensation of directors to ensure the compensation  realistically reflects the
responsibilities  and  risk  involved  in  being  an  effective  director.   The
Compensation  Committee is  presently  composed of three  outside and  unrelated
directors: Anthony L. Craig, Donald W. Paterson and Jonathan I. Wener.

Nominating Committee

      The  mandate  of the  Nominating  Committee  is to  seek  out  and  review
potential  additional  Board of  Director  candidates  as  submitted  by  search
consultants  retained by the Company, to evaluate the structure,  responsibility
and   composition   of  committees  of  the  Board  of  Directors  and  to  make
recommendations  to the Board of Directors with respect thereto.  The Nominating
Committee  is presently  composed of two outside and  unrelated  directors:  Dr.
Henry Simon and Hubert T. Lacroix and one inside and related  director:  Kirk K.
Mandy.  In view of the  contribution  to the Company of the  President and Chief
Executive  Officer,  Kirk K.  Mandy,  the


                                       81
<PAGE>

Board of Directors  considered the  participation of Mr. Mandy in the Nominating
Committee to be essential and concluded that he should continue to serve on such
committee.

Executive Committee

      The mandate of the Executive Committee is to supervise, control and manage
the  business  and  affairs of the  Company  when the Board is not in session in
order to execute in a timely fashion corporate plans and programs. The Executive
Committee is presently  composed of three outside and unrelated  directors:  Dr.
Henry  Simon,  Peter van  Cuylenburg  and Hubert T.  Lacroix  and two inside and
related  directors:  Kirk K.  Mandy  and  Jean-Jacques  Carrier.  In view of the
contribution to the Company of the President and Chief Executive  Officer,  Kirk
K. Mandy,  and the focus on  financial  performance  provided by the Senior Vice
President of Finance and Chief  Financial  Officer,  Jean-Jacques  Carrier,  the
Board of Directors  considered the participation of Messrs. Mandy and Carrier to
be essential and concluded that they should continue to serve on such committee.

Independence from Management

      The  Governance  Guidelines  state  that  the  independence  of a Board of
Directors is most simply  achieved by  appointing a chair who is not a member of
management.  The Chairman of the Board is separate from  management  and ensures
that the  Board of  Directors  can  function  independently  of  management.  In
addition,  the Board of Directors,  from time to time,  holds  sessions at Board
meetings without management present.

Decisions Requiring Prior Approval by the Board of Directors

      The Board of Directors has delegated to the President and Chief  Executive
Officer and senior management the responsibility  for the day-to-day  management
of the business of the Company,  subject to compliance  with the plans  approved
from time to time by the Board of Directors. In addition to those matters, which
must by law or by the  articles  of the  Company  be  approved  by the  Board of
Directors,   the  Board  of  Directors  has  specified  limits  to  management's
responsibility  as  recommended  in  the  Governance  Guidelines,   and  retains
responsibility  for  significant  changes  in the  Company's  affairs,  such  as
approval of major capital expenditures,  debt and equity financing  arrangements
and significant acquisitions and divestitures.

Other

      The  Board  of  Directors  considers  that  orienting  and  educating  new
directors is an important element of ensuring  responsible  corporate governance
and the Governance  Guidelines  recommend that a corporation should provide such
an orientation and education program for new directors.  Therefore,  in addition
to having extensive  discussions with the Chairman of the Board of Directors and
the  President  and Chief  Executive  Officer  with  respect to the business and
operations of the Company,  a new director receives a record of public and other
information  concerning the Company and prior minutes of recent  meetings of the
Board of Directors and applicable committees.  The details of the orientation of
each new director will be tailored to that director's individual needs and areas
of  interest.  By  ensuring  that Board  members  are  properly  informed of the
business  of the  Company,  the  Board  considers  that  it  complies  with  the
Governance Guidelines.

      A singular  position  description has been adopted for each  non-executive
member of the Board of Directors.

      The Board of Directors has determined to retain general responsibility for
dealing with corporate  governance issues,  while maintaining the flexibility of
asking certain  committees of the Board of Directors to address  specific issues
as they may arise from time to time. Therefore, a corporate governance committee
will not be created at this time.


                                       82
<PAGE>

      In certain circumstances, it may be appropriate for an individual director
to engage an outside advisor at the expense of the Company.  The Chairman of the
Board will determine if the  circumstances  warrant the engagement of an outside
advisor.

Employee Share Ownership Plan

      The Employee  Share  Ownership Plan was approved by the Board of Directors
in May 1997. The purpose of this plan is to enable employees to invest in equity
shares of the Company through employee savings.  Employees make contributions by
means of payroll deductions and common shares of the Company are purchased twice
per  month by  Montreal  Trust  Company  of Canada  (the  trustee  appointed  to
administer  the plan)  through  normal market  facilities.  The Company pays all
brokerage  commissions,  transfer  taxes and other  charges and  expenses of the
purchase and sale of the common shares except in connection  with sales of fewer
than 100 shares, in which case the employee is responsible for such costs.

1991 Stock Option Plan for Key Employees and Non-Employee Directors

      The 1991 Stock Option Plan for Key  Employees and  Non-Employee  Directors
(the "Option  Plan")  provides for the granting of  non-transferable  options to
purchase  common  shares to key  employees  and  non-employee  directors  of the
Company  and  its  subsidiaries,   as  determined  from  time  to  time  by  the
Compensation Committee.  The Option Plan was approved by the shareholders of the
Company at the 1991  Annual and  Special  Meeting of  Shareholders  and  certain
amendments  were approved by the  shareholders at the 1993, 1995 and 1998 Annual
and Special Meetings of Shareholders.

      All  options  granted  under the Option  Plan must be  exercised  within a
maximum of ten years  following  the date of grant or such other shorter time or
times as may be determined by the  Compensation  Committee at the time of grant.
Under the terms of the Option  Plan,  up to 25  percent of the common  shares in
respect of each option may be  purchased  after one year from the date of grant,
up to 50 percent after two years from the date of grant,  up to 75 percent after
three years from the date of grant and up to 100  percent  after four years from
the date of grant or at such  other  time or times as may be  determined  by the
Compensation Committee at the time of grant.

      The price at which  common  shares may be  purchased  upon  exercise of an
option is the average of the market price (as defined in the Option Plan) of the
common  shares on The Toronto  Stock  Exchange  for the five  trading day period
immediately preceding the date of grant.

      The  Option  Plan  provides  that,  in the event of the death of an option
holder,  the  exercise  period of any options  unexercised  at the date of death
would be accelerated so that the option  holder's legal personal  representative
would be  permitted  to purchase  and take  delivery of all common  shares under
option and not  purchased or delivered at the date of death,  during the 180-day
period  following  such  option  holder's  death  (but  in no  event  after  the
expiration date of such option).

      The Option Plan also provides that, in the event of the  termination of an
employee's  employment for any reason other than cause or death,  the employee's
options may be exercised,  to the extent the options are  exercisable  as of the
termination date, within 30 days following the date the employee's employment is
terminated;  provided,  however, that the Board of Directors of the Company may,
in its  discretion,  amend the terms of any  option to permit  the  employee  to
exercise such options as if such employee's  employment had not been terminated,
for up to a maximum of three  years  following  the date of  termination  of the
employee's  employment  (but  in no  event  after  the  expiration  date of such
option).  In the event the employee's  employment has been terminated for cause,
the  employee's  options  may be  exercised  only during the next  business  day
following  the date of personal  delivery of a written  notice by the Company to
the employee confirming such termination.

      The Option Plan further provides that, in the event of a change of control
(whether  in fact or in law) of the  Company  which  results  in a  non-employee
director being replaced,  the vesting period shall be waived with respect to the
options  then held by such  non-employee  director  in order to permit  the full
exercise of all outstanding  options then held by such person. In the event that
the  non-employee  director  ceases to act as a  director  of the  Company,  all
options held by such director that are then  exercisable may be exercised within
180


                                       86
<PAGE>

days following the announcement of the quarterly results next following the date
of resignation of such person (but in no event after the expiration date of such
option).  The Option Plan also  provides  that the  Compensation  Committee  may
determine that any option granted under the Option Plan shall include provisions
which  accelerate the date on which an option shall become  exercisable upon the
happening of such events as the  Compensation  Committee  may  determine  and as
permitted in the Option Plan.

      On January 11, 2000,  the Board of  Directors of the Company  decided that
all  unvested  stock  options held by each  director,  the  President  and Chief
Executive  Officer,  the five Senior Vice Presidents and any other executives of
the Company as may be  designated  by the Board of  Directors  from time to time
will be accelerated and become fully vested and  immediately  exercisable in the
event of (i) the  making by any  person of a  take-over  bid (as  defined in the
Securities Act (Ontario)) for the common shares of the Company, or (ii) a change
of control  (whether  in fact or in law and as more fully  defined in such Board
resolution) of the Company.

      Under the terms of the Option Plan, the maximum number of common shares as
to which options may be granted is 16,000,000 (representing approximately 14% of
the common  shares  outstanding  as of May 18,  2000).  As of May 18, 2000,  the
closing price of the common shares of the Company on The Toronto Stock  Exchange
was $29.45 and therefore the total market value as of such date of the 8,887,922
common shares  (excluding  3,607,200 common shares as to which options have been
previously  exercised)  that are or may be subject to  options  pursuant  to the
Option Plan was $261,749,303.

      During  Fiscal  2000,  the  Company  granted  options  to  purchase  up to
6,439,957 common shares to 2,111 employees and eight  non-employee  directors of
the Company at an average  exercise price of $13.03 per share,  of which options
for 785,000  common shares were granted to six executive  officers at an average
exercise price of $12.99 per share. During Fiscal 2000, one executive officer of
the  Company  exercised  options to  purchase  47,500  common  shares  having an
aggregate net value (being the market value less the exercise  price on the date
of the exercise) of $400,987.50 as of such date.

      As at May 18, 2000, there were  outstanding  under the Option Plan options
for an  aggregate  of 8,887,922  common  shares at prices  ranging from $1.10 to
$37.35 per share and expiring at various  dates  through  2007. Of such options,
options for an aggregate of 1,722,800 common shares were held by eight executive

Executive Termination Agreements

      The Company has entered into new executive  termination  arrangements with
eight senior executives (the  "Executives"),  including the five Named Executive
Officers,  to provide for certain  entitlements  in the event of the involuntary
termination of the Executives'  employment with the Company in any circumstances
considered to constitute a "termination  without good legal cause", as such term
is interpreted by the Courts of the Province of Ontario from time to time.

      The agreements generally provide that, in the event of such an involuntary
termination of employment  without good legal cause, the Executive would receive
as compensation: (i) for one Executive - three times the Executive's annual base
salary and annual target bonus,  subject to a total minimum of $3,000,000,  (ii)
for five  Executives - two times the  Executive's  annual base salary and annual
target  bonus,  and  (iii)  for two  Executives  - one and one  half  times  the
Executive's  annual base salary and average  annual  bonus,  based on the actual
bonus payments made to such Executive for the previous two fiscal years.

      In addition to such  compensation,  the  agreements  provide for continued
contributions to the Executive Pension Plan and continuous group life and health
benefits  coverage  during the three,  two or one and one half year  period,  as
applicable.  In all cases,  the Executives have a period of six months following
the date of  termination to exercise all stock options that are vested up to the
end of the exercise period.

      These agreements  replace the former VP Termination  Policy of the Company
as  well  as all  previous  compensation  arrangements  entered  into  with  the
Executives and were developed under the direction of the Compensation  Committee
in consultation  with outside  compensation  and  independent  legal advisors in
order to reflect current North American competitive market practices.

Compensation of Non-Employee Directors

      During the fiscal year ended March 31, 2000,  each  director who was not a
salaried officer of the Company or its  subsidiaries  received an annual stipend
of  $10,000  and a  director's  fee of $2,000  for each  meeting of the Board of
Directors  or any  Committee  thereof  attended  in person  or  $1,250  for each
telephone  meeting  of the  Board of  Directors  and for  each day  spent on the
affairs of the Company,  and was reimbursed for his expenses.  In addition,  the
Chairman of each  Committee  of the Board of  Directors  received an  additional
annual  fee of  $6,000.  The  Company  also  pays the  Chairman  of the Board of
Directors, when such person is not an employee of the Company, an annual stipend
of $100,000  (inclusive of Board and  Committee  meeting fees) and a per diem of
$2,500 for attendance on Company business to an annual maximum of $50,000.

REPORT ON EXECUTIVE COMPENSATION

      The  Compensation  Committee is comprised of three members of the Board of
Directors:  Jonathan I. Wener,  the Chairman of the Committee,  Anthony L. Craig
and Donald W. Paterson.

      It is the responsibility of the Compensation Committee to recommend to the
Board of Directors  compensation policies and levels,  compensation plans, stock
option/purchase  plans and benefit  plans.  The  Compensation  Committee is also
responsible  for  developing  and  reviewing  succession  plans that sustain the
long-term viability of the Company.

General Principles of Executive Compensation

      Compensation  of  executive   officers,   including  the  Named  Executive
Officers,  is determined by the Board of Directors upon  recommendations made by
the Compensation Committee.

      The Company's executive  compensation programs are designed to attract and
retain competent individuals who can ensure the current and long-term success of
the Company.  Each component of the Company's executive  compensation program is
designed to be  competitive  with  leading  Canadian  and U.S.  high  technology
companies of similar size.

      Executive  positions are formally evaluated by an independent  consultant,
using a widely  recognized  point-factor job evaluation  system,  resulting in a
specific  number of points for each  position.  Using total points to compare to
the external  comparator  group,  a market rate for each  executive  position is
established based on information furnished through independent survey data.

      The total  compensation  program for  executive  officers is  comprised of
three components: base salary, an annual incentive and a long-term incentive.

Base Salary

      Base  salary  recommendations  are  determined  based on  market  data for
positions of similar  responsibilities  and complexity in the comparator  group,
internal equity  comparisons and the  individual's  ability and experience.  The
Company's base salaries are competitive with those of the comparator group.

Annual Incentive Compensation Arrangements

      The Company's annual incentive plans are intended to incent individuals to
focus on achievement of current year Operating  Income targets and key strategic
performance  objectives  within each of the business  units.  Individual  target
awards  and  performance  weightings  within  the  plans  are  dependent  on the
individual's  ability to influence results.  Operating Income targets are set by
the Board of  Directors  at the  commencement  of the fiscal year and awards for
business unit and individual  performance are payable if the corporate Operating
Income  is at  least  75%  of  target  performance.  Payments  may be  made  for
performance below this threshold at the Board of Directors' discretion.

Long-Term Incentive

      Options  to  purchase  common  shares are  granted to the Named  Executive
Officers   and  other  key   employees  to  sustain   commitment   to  long-term
profitability and maximize shareholder value over the long term. Under the terms
and conditions of the Option Plan,  participants  are granted  options which are
exercisable  for periods of time determined by the  Compensation  Committee to a
maximum of ten years  following the date of grant at an exercise  price equal to
the average  market price of the  Company's  common  shares on The Toronto

Compensation of the President and Chief Executive Officer

      In July 1998,  Kirk K. Mandy was appointed  President and Chief  Executive
Officer  of  the  Company.   Mr.  Mandy's   compensation  was  approved  by  the
Compensation Committee and the Board of Directors.

      The  base  salary  and  long-term  incentive  components  of  Mr.  Mandy's
compensation  are  determined  in accordance  with the policies  applying to all
executive officers of the Company. Mr. Mandy's current base salary is $530,000.

      Mr. Mandy's annual discretionary bonus is determined,  at each fiscal year
end,  based  on  the   Compensation   Committee's   assessment  of  Mr.  Mandy's
performance, particularly in improving the Company's long-term profitability and
financial condition. For Fiscal 2000, Mr. Mandy earned a bonus of $795,000 based
on the Company's profitability.

The  Compensation  Committee of the Board of Directors,  whose names are set out
below,  has approved the issue of this Report on Executive  Compensation and its
inclusion in this Circular.

complex.  When such connections are distributed over a city or even larger area,
the LAN becomes a WAN or Wide Area Network.

      Light Emiting Diode (LED): An active semiconductor device that emits light
in a specific  wavelength  range in response to an electrical  signal applied to
it.

      Natural  Speech  Recognition:  The  ability  of a  computer  to  recognize
naturally spoken words, without requiring the speaker to "train" the system.

      PIN Diode Photodetector: An active semiconductor device that detects light
in a specific  wavelength  range and transforms the detected optical signal into
an electrical signal.

      Pin for Pin: A phrase used to describe a  semiconductor  component that is
not unique and is easily replaceable.

      Private  Branch  Exchange  (PBX):  A "branch" of the  telephone  company's
central office exchange,  usually located on the customer's premises, to provide
