INDUSTRY OVERVIEW

The global  markets for  communications  equipment  that  contain  our  products
continued to decline in 2002 primarily due to excess  capacity in  communication
service  provider  infrastructures,  excess inventory levels in the supply chain
and a slowing global  macro-economy.  Despite the fact that  connectivity to the
Internet  increased and web-based  applications  drove higher data  transmission
volumes,  service  providers in North America and Europe reduced spending on new
networking  equipment in 2002. This was largely the result of an overbuilding of
the  network  infrastructure  in the late  1990's  and early  2000 when  capital
markets  fueled  rapid  expansion  of data  networks  and  start-up  competitive
services.  Following this  expansionary  period,  many of the incumbent  service
providers  realized  they had excess  capacity  in their  systems  and could not
sustain  such high  levels of  spending  on new  equipment.  In  addition,  many
competitive service providers were unable to generate sufficient revenues to pay
for their new systems and were subsequently acquired, broken up and divested, or
filed for bankruptcy.

The  contraction  in capital  spending on networking  equipment in 2001 and 2002
resulted in fewer orders for our customers' equipment, and therefore a reduction
in  demand  for our  products.  We sell more  than 120  different  semiconductor
devices to the leading original  equipment  manufacturers  (OEMs) that, in turn,
sell  their  equipment  to end  customers  such  as  telecommunications  service
providers and  enterprises.  The overall  reduction in service  provider capital
spending,  combined  with high levels of  inventories  throughout  the  industry
supply chain, resulted in lower demand for our devices. While equipment spending
in the enterprise market (primarily corporations,  institutions and governments)
was relatively stable compared to service providers, it was not enough to offset
a broader  decline  in  activity  across  the  global  communications  equipment
industry.

Many service  providers  consider it  important  to add capacity and  technology
capability  to  limited  aspects  of  their  networks  as data  traffic  and the
associated  revenues are key growth drivers for their  operations going forward.
To capture a growing portion of this competitive  market,  service providers are
transitioning  their networks from  voice-centric  to data-centric  systems.  In
addition,  network utilization rates are increasing,  absorbing excess capacity,
but also slowing data transmission speed through service providers' networks. In
this environment, it is critical for service providers to upgrade their networks
with more  efficient  equipment  enabling  them to lower  operating  costs while
handling  the  increasing  amount of traffic.  The service  providers  must also
upgrade equipment while lowering capital spending.

                                       3


In simple terms, the Internet is a hybrid series of networks comprised of copper
wires,  coaxial cables, and fiber optic cables.  These networks carry high-speed
traffic in the form of electrical and optical  signals that are  transmitted and
received  by complex  networking  equipment.  To ensure this  equipment  and the
various networks can easily  communicate with each other, the OEMs and makers of
communications  semiconductors have developed numerous communications  standards
and protocols for the industry.  These  communications  protocols make it easier
for  complex  high-speed  data  traffic  to be sent and  received  reliably  and
efficiently - - whether intra-office, across the country, or internationally.

One industry  standard that packages  information  into a fixed-size cell format
for  transportation  across networks is ATM or Asynchronous  Transfer Mode. Many
service  providers  deploy  equipment that handles this protocol  because it can
support voice, video, data, and multimedia applications simultaneously.

Another  established  industry  standard is called SONET or Synchronous  Optical
Network for high capacity data communication  over fiber optic systems.  This is
used in the Americas and parts of Asia, with the equivalent standard in the rest
of the world called SDH or Synchronous Digital Hierarchy.

In addition to using SONET to increase the  bandwidth,  or capacity of, in their
networks,  many  system  operators  have  also  deployed  equipment  that uses a
technology called dense wave division  multiplexing.  Rather than transmitting a
single  light signal over an optical  fiber,  dense wave  division  multiplexing
allows many  different  light  signals  (each of a different  wavelength)  to be
transmitted  simultaneously.  By deploying this technique at higher transmission
rates, carriers can move more signals across transmission lines.

IP is a transport protocol that maintains network information and routes packets
across  networks.  While IP  packets  are larger and can hold more data than ATM
cells,  service  providers often have  difficulty  providing the same quality of
service with IP because it is not optimized for  time-sensitive  signals such as
video and voice services.

Ethernet is another  protocol that is used  extensively in data  transmission in
local area networks  (LAN) and is now being used in wide area networks  (WAN) as
well.  Service  providers  are  beginning  to deploy  ethernet  because they are
familiar  with the  protocol  and it is a  relatively  efficient  way to  handle
increasing amounts of data moving from the LAN to the WAN.

In some service  provider  networks,  a traffic  bottleneck  can occur where the
high-speed  long-haul traffic is handed off to networking equipment in the metro
area or where storage networks are being  inter-connected.  In general,  service
providers have invested less to enhance the infrastructure in these areas and as
a result,  many of these  systems  have  insufficient  capacity  to  handle  the
increasing level of data traffic.

In response, many OEMs are designing faster and more complex equipment to handle
the higher  volumes in the network.  This  equipment must be able to accommodate
various  protocols  and  formats,  including  cell-based  ATM  and  packet-based
Internet Protocol (IP).

To accommodate  these  different  protocols and the growing demand for services,
many service  providers are requiring  OEMs to provide more complex,  integrated
solutions  in a shorter  time  period.  At the same time,  some of the OEMs have
undergone  significant  corporate  restructurings  and have fewer  resources and
technical staff internally to design their own custom solutions.  This,  coupled
with  the  rising  cost of  custom  semiconductors,  has  resulted  in the  OEMs
outsourcing  more of their  communications  integrated  circuit  requirements to
companies such as PMC-Sierra. This has brought about the acceleration of the use
of standard products of the kind that PMC-Sierra designs and develops.

                                       4


By  leveraging  the  knowledge  and  technical  expertise of  companies  such as
PMC-Sierra, the OEMs are able to focus their efforts on their core competencies.
In many cases,  it can take several  years before a new silicon chip or chip set
can be designed,  manufactured,  tested,  and released to full  production for a
customer.  It is essential,  therefore,  that  companies  like  PMC-Sierra  that
develop the chips to be  incorporated  into the OEM equipment  work very closely
with their OEM customers so that together they can optimally  meet the equipment
needs of the service providers.


PRODUCTS

We  have  more  than  120  revenue-producing  products  in  our  portfolio.  Our
networking  products  comprise  communications   semiconductors  -  -  including
microprocessors  - -  that  are  used  in  many  different  types  of  equipment
throughout  the network  infrastructure.  While our current  networking  product
development  efforts  are  focusing  on  all  the  four  areas  of  the  network
infrastructure  described  below,  less  than 10% of our  current  revenues  are
derived from the storage and consumer  markets.  One of our key strategies is to
broaden into these markets.

Our  non-networking  segment,  comprised  of a single  chip  used in a  consumer
medical   device,   wound  down  in  the  second  quarter  of  2002,  with  only
insignificant revenues thereafter to meet remaining customer requirements.

Our  networking  products are sold  primarily  into four areas of the  worldwide
network  infrastructure,  which we call Metro, Access,  Enterprise/Storage,  and
Consumer-related  markets.  Many of our products are designed with  standardized
interfaces  between  chips so our  customers  can easily  develop and  implement
solutions involving multiple PMC-Sierra products.

The  following  briefly  describes  PMC-Sierra's  view  of  the  Metro,  Access,
Enterprise/Storage and Consumer-related areas of the internet infrastructure and
some  typical  equipment  that may  include our chips and  chipsets.  Due to the
complexity  of the  telecommunications  network,  it is not  possible to sharply
delineate the networking  functions or markets served. In addition,  many of our
products  may be used in  multiple  classes  of  networking  equipment  that are
deployed  across all of the market  areas  identified  below,  while some of our
other  products  have  highly  specialized   applications.   For  example,   our
microprocessors can be used in many networking  equipment  applications (such as
high-speed  routers or networked  printers),  while our Paladin chip may only be
used in a single application  (power  amplification for wireless base stations).
In some situations,  different OEMs might use our chips or chipsets in equipment
addressing more than one of the market areas noted below.

   o     Access:  this  area of the  telecommunications  network  infrastructure
         encompasses wired and wireless equipment that aggregates  transmissions
         from the home or office and connects  that traffic to the metro and the
         wide area network (WAN). For example,  our semiconductors would be used
         in  equipment  such as digital  subscriber  line  access  multiplexers,
         wireless  base  stations,  add-drop  multiplexers  (which  add and drop
         signals and streams of data from optical  networks) and switches (which
         direct the data traffic to other destinations within the network).

                                       5


   o     Metro: the metropolitan,  or metro area, of the internet infrastructure
         is predominantly a fiber optic-based  network that provides  high-speed
         communications  and data transfer over a city center or regional  area.
         This portion of the network  manages  traffic inside its own region and
         manages traffic between the access and long-haul transport networks for
         inter-city  or  international  transmission.  Our  products are used in
         metro  equipment  such as switches  and routers that gather and process
         signals in  different  protocols,  and then  transmit  them to the next
         destination as quickly and efficiently as possible.

   o     Enterprise/Storage: this area of the network includes equipment that is
         deployed  primarily  in the  office for data  communications  and other
         local area  network  applications.  Our  products are used in equipment
         such as medium to high-end laser jet printers in the office, as well as
         switches  and storage  devices  that enable data to be  transferred  to
         local telecommunications networks. It includes network attached storage
         equipment  and storage area networks for the  management,  transmission
         and  storage  of  large  amounts  of  data  utilized  by   enterprises,
         corporations and government agencies.

   o     Consumer:   this  area  includes   telecommunications   equipment  used
         primarily by individuals in their homes for entertainment purposes. For
         example,  some of our lower-end  microprocessors  are used in equipment
         such  as  set-top  boxes,   high-definition   TVs  and  personal  video
         recorders.

Our chips and chipsets can also be divided into the broadly  defined  functional
categories  identified  below. As with  descriptions of the network,  particular
categories may overlap and a device may be present in more than one category. In
addition,  some products,  particularly  multiple chip sets, integrate different
functions and could be classified in one or more categories.  For example,  some
of our products both convert  high-speed analog signals to digital signals,  and
also split or combine various transmission signals.

   o     Line interface units: these devices,  also referred to as transceivers,
         transmit and receive signals over a physical medium such as wire, cable
         or fiber.  The line  interface  unit  determines  the speed and  timing
         characteristics of the signals, and may also convert them from a serial
         stream of data into a parallel stream before they are further processed
         for transmission to the next destination.

   o     Framers  and  mappers:  before  the  data  can  be  sent  to  the  next
         destination, it must be converted into a proper format for transmission
         in the network.  For example,  the framing  function  arranges the bits
         into different size formats, commonly referred to as "cell" or "packet"
         formats,  and attaches the  appropriate  information  to the formats to
         ensure  they  reach  their  destinations.  In  turn,  this  data may be
         inserted into other  frames,  such as SONET  frames,  for  transmission
         across high-speed fiber optics.

   o     Packet and cell  processors:  these  devices  examine  the  contents of
         cells,  or  packets,  and  perform  various  management  and  reporting
         functions.  For  instance,  a switch or router may use a packet or cell
         processor  to  determine  if a  signal  is  voice  or video in order to
         allocate the proper  amount of  bandwidth.  Service  providers  can use
         information  gathered  by the cell or  packet  processor  to  determine
         customers' network usage and charge the appropriate service fee.

   o     Traffic  managers  and  switch  fabrics:   traffic  managers  organize,
         schedule and queue cells and packets  into and out of switches.  Switch
         fabrics  interconnect  the wires and  fibers,  allowing  the data to be
         routed to its intended destination.

                                       6


   o     Serializers/Deserializers:  these devices  convert  networking  traffic
         between slower speed parallel  streams and higher speed serial streams.
         OEMs  use  serial   streams  to  reduce   networking   equipment   line
         connections,  and  parallel  streams to allow them to apply  lower cost
         traffic management technologies.

   o     Microprocessors: these devices perform the high-speed computations that
         help  identify  and  control  the flow of signals  and data in the many
         different  types  of  network  equipment  used  in the  communications,
         enterprise and consumer markets.


STRATEGY

Our  high-speed  semiconductor  solutions  are based on our strong  knowledge of
network applications,  system requirements and networking protocols.  To achieve
our goal of growing and profitably  expanding our business,  we are pursuing the
following key strategies:

Leverage technical expertise across diverse base of applications:

We have a history of analog, digital, mixed signal and microprocessor  expertise
and we integrate many functions and protocols into our products. We leverage our
common technologies and intellectual property across a broad range of networking
equipment.  Many  OEMs  recognize  they can  obtain  highly  complex,  broadband
communications  technology  "off the shelf" from  companies  such as  PMC-Sierra
rather than dedicating their own resources to develop custom chips. We intend to
take advantage of our customers'  growing  requirements to outsource more of the
silicon  content  in their  networking  equipment  which  will allow the OEMs to
reduce their development costs and improve  time-to-market while differentiating
their products in other ways.

Broaden our business into the Enterprise, Storage and Consumer markets:

The  majority  of our  products  are used by OEMs  that  sell  their  networking
equipment to telecommunications service providers worldwide. Over the past year,
however,  we have been  focused  on  directing  many of our  existing  and newly
designed    products   into   new   markets.    For   example,    our   advanced
serialization/de-serialization  devices  are now being used in  transceiver  and
serial  backplane   applications  in  storage  area  networking  and  enterprise
networking  equipment.  Our lower-speed  microprocessors are being designed into
advanced multi-function devices as well as going into consumer applications such
as personal  video  recorders,  set-top  boxes and  high-definition  TVs. We are
working  closely with some of the largest  players in the enterprise and storage
markets  to help  these  customers  design and  develop  standard  semiconductor
solutions that will lower their costs and improve their time to market.

Increase our presence in Asian markets:

Over the past decade,  we have been  developing  strong  relationships  with our
Asian  customers.  In 2002,  just under  one-third  of our total  revenues  were
generated in the Asia Pacific region. Some of our largest customers in Japan and
Korea include Fujitsu,  Ricoh, NEC, Samsung and LG Electronics.  In addition, we
are gaining new customers, many of which are located in the People's Republic of
China,   such  as  ZTE,   Huawei   Technologies,   Fiberhome   Telecommunciation
Technologies,  and Alcatel  Shanghai Bell.  These customers are broadening their
product  offerings to meet the growing  network  infrastructure  requirements in
China and other Asian markets.  To improve our customer  service and penetration
into this  region,  we  appointed a new vice  president to head our Asia Pacific
sales and support team, headquartered in Shanghai.  PMC-Sierra plans to continue
increasing  the  number  of  sales/marketing   personnel  in  our  Asia  Pacific
operations and to add new distribution capabilities in the regional markets.

                                       7


Provide first-class products, customer service and technical support:

We work very closely with our  customers to ensure they get the best service and
technical support required to assist them with their development efforts. As the
marketplace for telecommunications  equipment suppliers slowly consolidates,  we
believe  our  largest  customers  and their  products  will  take an  increasing
percentage of the overall market in their areas of expertise.  Customers such as
Cisco, Hewlett Packard, Lucent, Nortel, Alcatel,  Samsung,  Fujitsu, Ricoh, ZTE,
Huawei and Juniper are aligning their design and  manufacturing  operations with
key suppliers like PMC-Sierra.


SALES, MARKETING AND DISTRIBUTION

Our sales and  marketing  strategy  is to have our  products  designed  into our
customers'  equipment  by  developing  superior  products  for which we  provide
premium service and technical support.  We maintain close working  relationships
with many of our  customers.  Our marketing  team is focused on  developing  new
products  that meet the needs of our  customers  in our target  markets.  We are
often involved in the early stages of design concerning our customers' plans for
new equipment.  This helps us determine if our existing  products can be used in
their new equipment or if new devices need to be considered for the application.
To assist us in our planning process, we are in regular contact with our largest
customers to discuss industry trends,  emerging  standards and their new product
requirements.

To  promote  our  products,   our  marketing   team  is  actively   involved  in
demonstrating our devices with other industry suppliers and providing  technical
information  at trade shows held in North  America,  Asia and Europe.  Technical
support is  essential  to our  customers'  success,  and we provide this through
field application engineers,  technical marketing and factory systems engineers.
We also  provide  more  detailed  information  and support for our product  line
through our corporate website and special customer-accessible extranet sites. We
believe that providing  comprehensive product service and support is critical to
shortening  customers'  design cycles and maintaining a competitive  position in
the networking market.

We sell our products  both  directly and through  distributors  and  independent
manufacturers'  representatives.  In 2002,  approximately 36% of our orders were
shipped through our distributors;  approximately 45% were sent by us directly to
contract  manufacturers  selected by OEMs; and the balance were sent directly to
our OEM customers.

Our largest  distributor  is Memec Group  Holdings  Ltd.  which  represents  our
products worldwide (excluding Japan, Israel, Taiwan and Australia).  Many of our
customers  are seeking to reduce supply chain costs and are  requesting  that we
ship more of our  products  directly  to the  contract  manufacturers  they have
selected.  Based on this trend,  we expect that over time our largest  customers
will  require  that we ship a higher  percentage  of their  orders  directly  to
contract  manufacturers  and a lower  percentage  will be  shipped  through  our
distributors.

A summary of our domestic and  international  net revenues and long-lived assets
is presented in Note 13 to the Consolidated Financial Statements in Item 8. More
than half of our net revenues were generated in the United States in each of the
three years ended December 31, 2002.

For a  discussion  of  risks we face due to our  international  operations,  see
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations - Factors That You Should Consider Before Investing in PMC-Sierra" in
Item 7.

Cisco Systems and  Hewlett-Packard  each  represented  more than 10% of our 2002
revenues based on total sales to end customers  through  distributors,  contract
manufacturers  or direct sales. Our sales outside of the United States accounted
for 45% of total revenue in 2002, 42% in 2001, and 38% in 2000.


MANUFACTURING

We are a fabless  company,  meaning we do not own or operate  foundries  for the
production of silicon wafers from which our products our made.  Instead,  we use
independent foundries and chip assemblers for the manufacture of our products.

Typically,  the  manufacture of our chips requires 12-16 weeks. We refer to this
as our lead-time.  Based on this lead-time, our team of production planners will
initiate a purchase order with an independent  foundry to fabricate the required
wafers.  The wafers once fabricated must be probed,  or inspected,  to determine
usable from  unusable chip parts,  referred to as die, on the wafer.  The wafers
are sent to an outside assembly house where they are cut and the good die are in
turn packaged into chips. The chips are then run through various  electrical and
visual tests before delivery to the customer. With most of our products, we have
the option to probe the wafers or test the final chips  in-house or  subcontract
the probing or testing to independent subcontractors.

We receive more than 90% of the silicon wafers from which we derive our products
from  Chartered   Semiconductor   Manufacturing   Ltd.   ("Chartered"),   Taiwan
Semiconductor  Manufacturing  Corporation  ("TSMC"),  and IBM. These independent
foundries produce our networking  products at feature sizes down to 0.13 micron.
By using  independent  foundries to fabricate our wafers,  we are better able to
concentrate our resources on designing, development and testing of new products.
In addition,  we avoid much of the fixed capital and operating costs  associated
with owning and operating fabrication or chip assembly facilities.

We have supply agreements with both Chartered and TSMC. We have made deposits to
secure access to wafer fabrication  capacity under both of these agreements.  At
December 31, 2002 and 2001, we had $22 million in deposits with these companies.
Under these agreements,  the foundries must supply certain  quantities of wafers
per year. Neither of these agreements have minimum unit volume  requirements but
we are obliged under one of the  agreements to purchase a minimum  percentage of
our  total  annual  wafer  requirements  provided  that the  foundry  is able to
continue to offer competitive  technology,  pricing,  quality and delivery.  The
agreements may be terminated if either party does not comply with the terms.

Wafers  supplied by outside  foundries  must meet our incoming  quality and test
standards.  We conduct a portion of our test operations on advanced mixed signal
and digital test equipment in our Burnaby facility. The remainder of our testing
is performed predominantly by independent U.S. and Asian companies.

RESEARCH AND DEVELOPMENT

Our  current  research  and  development  efforts are  targeted  at  integrating
multiple  channels  or  functions  on single  chips,  broadening  the  number of
products we provide to address varying protocols and networking  functions,  and
increasing the speeds at which our chips operate.

At the  end of  fiscal  2002,  we  had  design  centers  in  the  United  States
(California,  Oregon,  Maryland,  and  Pennsylvania),  Canada (British Columbia,
Saskatchewan,  Manitoba, Ontario and Quebec), Ireland, and India. On January 16,
2003,  we announced a corporate  restructuring  to further  reduce our operating
expenses.  As a result of this  restructuring,  we will be  closing  our  design
centers in Maryland, Ireland and India during 2003.

We spent $137.7  million in 2002,  $201.1 million in 2001, and $178.8 million in
2000 on research and development.

In 2000, we also expensed $38.2 million of in process  research and development,
$31.5 million of which related to the acquisition of Malleable  Technologies and
$6.7 million of which related to the acquisition of Datum Telegraphic.


BACKLOG

We sell primarily pursuant to standard purchase orders. Our customers frequently
revise the quantity  actually  purchased  and the shipment  schedules to reflect
changes in their needs.  We believe  orders placed for delivery in excess of six
months are not firm orders.  As of December  31,  2002,  our backlog of products
scheduled  for shipment  within six months  totaled  $36.6  million.  Unless our
customers  cancel or defer to a subsequent  year a portion of this  backlog,  we
expect this entire  backlog to be filled in 2003.  Our backlog of products as of
December 31, 2001 for shipment within six months totaled $35.7 million.

Our backlog includes backlog to our major  distributor,  which may not result in
revenue,  as we do not recognize  shipments to our major  distributor as revenue
until our distributor has sold our products  through to the end customer.  Also,
our customers may cancel, or defer to a future period, a significant  portion of
the backlog at their discretion  without penalty.  Accordingly,  we believe that
our backlog at any given time is not a meaningful indicator of future revenues.


COMPETITION

We typically face competition at the design stage when our networking  customers
determine  which  communications  semiconductor  components to use in their next
generation equipment designs.

Most of our  customers  choose a particular  semiconductor  component  primarily
based on whether the component:

   o        meets the functional requirements,

   o        addresses the required protocols,

   o        interfaces easily with other components in a design,

   o        meets power usage requirements, and

   o        is priced competitively.

                                       10


OEMs are  becoming  more  price  conscious  than in the past as a result  of the
downturn in the telecommunications  industry, and as semiconductors sourced from
third party suppliers  comprise a greater portion of the total materials cost in
OEM  equipment.  We have also  experienced  aggressive  price  competition  from
competitors  that are seeking to enter into the markets in which we participate.
These  circumstances may make some of our products less competitive,  and we may
be forced to decrease our prices significantly to win a design.

In addition to price,  OEMs will also  consider the quality of the supplier when
determining  which component to include in a design.  Many of our customers will
consider  the  breadth  and  depth of the  supplier's  technology,  as using one
supplier for a broad range of technologies can often simplify and accelerate the
design of next generation equipment. OEMs will also consider a supplier's design
execution  reputation,  as many OEMs  design  their  next  generation  equipment
concurrently  with the  component  design.  As well,  consideration  is given to
whether the OEM has pre-qualified the supplier,  as this ensures that components
made by that supplier will meet the OEM's quality standards.

Our  competitors  may be classified  into three major groups.  First, we compete
against  established  peer-group  semiconductor  companies  that  focus  on  the
communications  semiconductor  business.  These companies include Agere Systems,
Applied  Micro  Circuits  Corporation,   Broadcom,  Exar  Corporation,  Conexant
Systems,  Marvell Technology Group,  Multilink Technology  Corporation,  Silicon
Image, Transwitch and Vitesse Semiconductor.  These companies are well financed,
have  significant   communications   semiconductor   technology   assets,   have
established sales channels, and depend on the market in which we participate for
the bulk of their revenues.

Other  competitors  include  major  domestic  and  international   semiconductor
companies,  such  as  Agilent,  Cypress  Semiconductor,  Intel,  IBM,  Infineon,
Integrated  Device  Technology,  Maxim  Integrated  Products,  Motorola,  Nortel
Networks and Texas Instruments.  These companies are concentrating an increasing
amount of their  substantial  financial  and other  resources  on the markets in
which we participate.

Emerging companies also provide  competition in our segment of the semiconductor
market. We are aware of venture-backed companies that focus on specific portions
of our broad range of products.  These companies  could  introduce  technologies
that may make one or more of our integrated circuits obsolete.

Over the next few years,  we expect  additional  competitors,  some of which may
also have greater  financial and other  resources,  to enter the market with new
products.

We are also  expanding  into some  markets,  such as the  storage  and  wireless
infrastructure  and  generic  microprocessor   markets,  that  have  established
incumbents  with  substantial  financial  and  other  resources.  Some of  these
incumbents  derive a majority of their earnings from these markets.  We expect a
strong increase in competition in these markets.

LICENSES, PATENTS AND TRADEMARKS

We rely in part on patents to protect our  intellectual  property  and have been
awarded  137  U.S.  and  63  foreign  patents  for  circuit  designs  and  other
innovations used in the design and architecture of our products. In addition, we
have 102 patent  applications  pending in the U.S. Patent and Trademark  office,
and 8  patent  applications  pending  in other  countries.  Our  patents  expire
typically  20 years  from the  patent  application  date if  accepted,  with our
existing patents expiring between 2010 and 2021.

We do not consider our business to be materially  dependent upon any one patent,
although  we believe  that a strong  portfolio  of patents  combined  with other
factors  such  as  our  innovative  ability,  technological  expertise  and  the
experience  of  our  personnel  are  important  to  compete  effectively  in the
industry.  A portfolio of patents also provides the  flexibility to negotiate or
cross  license  intellectual  property  with other  semiconductor  companies  to
incorporate other features in our products.

To protect  our other  intellectual  property  we rely on mask work  protection,
trademarks,   copyrights,   trade   secret  laws,   employee   and   third-party
nondisclosure agreements, and licensing arrangements.

Our only material license is the MIPS microprocessor  architecture  license from
MIPS Technologies  Inc., on which our  microprocessor-based  products are based.
While the desktop  microprocessor market is dominated by the Intel Corporation's
"x86"  complex  instruction  set  computing,  or  CISC,  architecture,   several
microprocessor  architectures  have  emerged for other  microprocessor  markets.
Because of their higher performance and smaller space requirements,  most of the
competing architectures, like the MIPS architecture, are reduced instruction set
computing,  or RISC  architectures.  The MIPS  architecture is widely  supported
through   semiconductor   design  software,   operating  systems  and  companion
integrated  circuits.  Because  this  license  is the  architecture  behind  our
microprocessors,  we must be able to retain the MIPS license in order to produce
our follow-on microprocessor products.

PMC and its logo are our registered  trademarks and service marks.  We own other
trademarks  and service  marks not  appearing in this Annual  Report.  Any other
trademarks used in this Annual Report are owned by other entities.


EMPLOYEES

As of December 31, 2002, we had 1,099  employees,  including 679 in Research and
Development, 118 in Production and Quality Assurance, 203 in Marketing and Sales
and 99 in Administration. In January 2003, we announced a restructuring which we
expect  to  reduce  our  headcount  to 924  employees.  Our  employees  are  not
represented by a collective  bargaining  agreement and we have never experienced
any related work stoppage. We believe our employee relations are good.



ITEM 2.  Properties.

PMC leases or owns properties in twenty-seven locations worldwide. Approximately
45% of the space  leased by PMC was  unoccupied  at December  31,  2002.  We are
actively trying to sublease or negotiate our exit from these excess facilities.

We lease a total of 431,000  square  feet in four  separate  buildings  in Santa
Clara, California, to house the majority of our US design, engineering,  product
test, sales and marketing operations.

                                       12


Our Canadian operations are located in Burnaby,  British Columbia where we lease
241,000 square feet of office space in five separate buildings.  These locations
support  a  significant  portion  of  our  product  development,  manufacturing,
marketing,  sales and test activities. We also operate ten additional research &
development centers:  four in Canada, three in the US, two in Ireland and one in
India.

We have fourteen sales offices  worldwide,  with locations in Europe,  Asia, and
North America.

All of our  offices  are in  leased  premises.  We  also  own two  buildings  on
approximately  19 acres of land near our Canadian  headquarters in Burnaby.  The
property was purchased as a development site and is being held with the eventual
potential of building our own  facility to replace our existing  leased  Burnaby
premises.

In January  2003,  we announced  our intention to close four of our research and
development  sites located in the US, Ireland and India. We will also close five
of our sales offices located in the US and Europe.

     December 31 has been used as the fiscal year end for ease of presentation.

(2)  Results  for the year  ended  December  31,  2002  include  a $4.0  million
     allowance for inventories in excess of twelve-month demand recorded in cost
     of revenues and a $15.3 million charge for impairment of other  investments
     recorded in gain (loss) on investments.  In accordance with the adoption of
     Statement of Financial  Accounting  Standard No. 142,  "Goodwill  and Other
     Intangible Assets", we ceased amortizing goodwill at the beginning of 2002,
     thereby eliminating  amortization  expense of approximately $2 million. See
     Note 1 of the Consolidated Financial Statements.

ITEM 7. Management's  Discussion and Analysis of Financial Condition and Results
of Operations.

The  following  discussion  of  the  financial  condition  and  results  of  our
operations  should  be read  in  conjunction  with  the  Consolidated  Financial
Statements and notes thereto included elsewhere in this Annual Report.


Net Revenues ($000,000)

                               2002      Change     2001       Change     2000
- --------------------------------------------------------------------------------

Networking products          $ 212.7      (29%)    $ 300.2      (55%)    $ 665.7

Non-networking  products     $   5.4      (76%)    $  22.5      (22%)    $  29.0

Total net revenues           $ 218.1      (32%)    $ 322.7      (54%)    $ 694.7




Net revenues for 2002 decreased by $104.6 million,  or 32%, from net revenues in
2001, which decreased by $372.0 million, or 54%, from net revenues in 2000.

         Networking

In 2001 and 2002, our net revenues were impacted by several factors:

   o     weakness in the US and global economies

   o     depressed   spending   levels  by   telecommunications   companies  and
         enterprises   that  incorporate  our  products  into  their  networking
         equipment

   o     excess inventory levels at OEM's

Prior  to the  onset of these  adverse  market  conditions,  our  customers  had
accumulated  significant  inventories of our products in  anticipation  of rapid
networking equipment sales growth. In 2001, rather than grow, the market for our
customers'  products  contracted,  causing a sharp decline in the demand for our
products.  Consequently,  our networking revenues declined $87.5 million, or 29%
in 2002 from 2001 and declined  $365.5  million,  or 55%, in 2001 from 2000. The
lower  demand of our  products  in 2002 was not as severe as the decline in 2001
from 2000, as our customers  consumed a portion of the excess inventories of our
products they held.

The majority of the revenue  decline  resulted from reduced volume  shipments of
our parts,  however  price  reductions  for high volume  products  also  reduced
revenues by 4% and 5% in 2002 and 2001 respectively.

         Non-networking

Non-networking  revenues  declined  $17.1  million,  or 76%,  in 2002  and  $6.5
million,  or 22%, in 2001 due to decreased unit sales to our principal  customer
in this  segment.  This  product  reached  the end of its life  after  the first
quarter of 2002, with only insignificant revenues thereafter.

Non-networking products                     $   2.3      (76%)    $   9.4      (27%)    $  12.8
   Percentage of non-networking revenues        43%                   42%                   44%

Total gross profit                          $ 128.5      (31%)    $ 185.5      (65%)    $ 528.5
   Percentage of net revenues                   59%                   57%                   76%



Total gross  profit for 2002  decreased  by $57.0  million,  or 31%,  from gross
profit in 2001, which decreased by $343.0 million,  or 65%, from gross profit in
2000.

         Networking

Our  networking  gross profit for 2002 decreased by $49.9 million from 2001. The
decrease in networking  gross profit related  primarily to lower sales volume in
2002 compared to 2001 partially offset by a lower write-down of excess inventory
of $4.0  million in 2002  compared  with a $20.7  million  write-down  of excess
inventory in 2001.

Our  networking  gross profit for 2001  decreased  by $339.6  million from 2000.
Excluding the $20.7 million write-down of excess inventory in 2001, the decrease
in  networking  gross  profit in 2001  related  primarily  to the reduced  sales
volume.

While  networking gross profit as a percentage of networking  revenues  remained
constant at 59% for 2002 and 2001, the following  factors impacted the margin in
2002:

   o     a write-down of excess inventory in 2002 was $16.7 million lower than a
         similar  write-down  in 2001,  increasing  gross profit by 8 percentage
         points,

   o     reduced shipment  volumes resulted in manufacturing  costs being spread
         over fewer units  resulting  in lowering  gross  margin by 5 percentage
         points, despite reducing manufacturing costs by $3.9 million.

   o     a shift in mix from the higher margin networking products to those sold
         into higher  volume lower margin  applications  further  reduced  gross
         profit by 3 percentage points.

Our networking gross profit as a percentage of networking  revenues decreased 18
percentage  points from 77% in 2000 to 59% in 2001. This decrease  resulted from
the following factors:

   o     a $20.7  million  write-down  of excess  inventory  which lowered gross
         profit by 7 percentage points,

   o     a shift in product mix towards  lower margin  products,  which  lowered
         gross profit by 6 percentage points, and

   o     the effect of applying fixed  manufacturing costs over reduced shipment
         volumes which lowered margins by 5 percentage points.

         Non-networking

Non-networking  gross  profit  for both 2002 and 2001  decreased  as a result of
declining sales volume. This product reached the end of its life in 2002.

         Research and Development Expenses

Our research and development,  or R&D, expenses decreased $63.4 million, or 32%,
in 2002 compared to 2001 due to the Company's  restructuring  and cost reduction
programs  implemented  in the first and fourth  quarters of 2001. As a result of
these programs,  we reduced our R&D personnel and related costs by $34.0 million
and other R&D expenses by $29.4 million compared to 2001.

Our R&D expenses for 2001 were $22.3  million,  or 12%,  higher than 2000 as the
effect of  increased  hiring and  expansion  of  development  programs and costs
during 2000 was only partially  offset by the  restructuring  and cost reduction
programs  implemented in 2001. We reduced our R&D personnel by 34% by the end of
2001  from the end of 2000 but  because  we made  substantial  additions  to our
personnel  and tools during the latter part of 2000 and because we realized less
than 3 months' savings from our fourth-quarter restructuring,  our R&D personnel
and  related  costs for 2001  exceeded  2000 by $7.2  million  and our tools and
equipment costs for 2001 exceeded 2000 by $11.8 million.

Acquisitions  that we completed during 2000 and accounted for under the purchase
method increased our 2001 R&D expenses by $4.2 million compared to 2000.

                                       19


         Marketing, General and Administrative Expenses

Our marketing, general and administrative,  or MG&A, expenses decreased by $26.9
million,  or 30%, in 2002 compared to 2001. Of this  decrease,  $4.2 million was
attributable to lower variable sales  commissions as a result of lower revenues.
The remainder was attributable to the restructuring and cost reduction  programs
implemented in 2001,  which reduced our MG&A personnel and related costs by $9.7
million and other MG&A expenses by $13.0 million compared to 2001.

Our MG&A expenses  decreased by $10.3 million,  or 10%, in 2001 compared to 2000
due primarily to a $12.0 million reduction in sales  commissions  resulting from
the decline in our revenues.  The  restructuring  programs  implemented  in 2001
reduced our MG&A personnel by 30% from the end of 2000, but due to growth in the
latter part of 2000  resulted in only a 3%  year-over-year  decrease in our MG&A
personnel costs.  This decrease in personnel costs combined with the decrease in
recruitment  costs  resulting  from less  hiring  activity in 2001 was more than
offset by increases in the cost of facilities due to the prior year's expansion.

Acquisitions  that we completed during 2000 and accounted for under the purchase
method increased our 2001 MG&A expenses by $1.2 million compared to 2000.

         Amortization of Deferred Stock Compensation

We recorded a non-cash charge of $2.8 million for amortization of deferred stock
compensation  in 2002 compared to a non-cash charge of $41.2 million in 2001 and
$36.3 million in 2000.

Deferred stock compensation  charges decreased by $38.4 million in 2002 compared
to 2001 because we accelerated vesting for certain employees  terminated as part
of our 2001 restructurings. This acceleration of vesting also resulted in higher
charges in 2001 compared to 2000.

         Impairment of Property and Equipment

In 2002, we recorded an impairment charge of $1.8 million reflecting a reduction
in the estimated fair value of a product tester. This equipment was removed from
service because lower  manufacturing and product development volumes resulted in
excess product tester capacity.

There were no impairments of property and equipment in 2001 or 2000,  other than
those assets impaired as a result of our 2001 restructurings as described below.

         Restructuring Costs and other Special Charges

On January 16, 2003, we announced  that we are  undertaking a further  corporate
restructuring to further reduce our operating  expenses.  The restructuring plan
includes the  termination  of  approximately  175  employees  and the closure of
design centers in Maryland,  Ireland and India.  We expect that we will record a
restructuring charge for workforce  reduction,  facility lease costs and related
asset  impairments as these liabilities will be incurred in the first and second
quarters of 2003.

During the year,  we paid out $27.5  million in  connection  with  October  2001
restructuring  activities.  See "Critical  Accounting  Policies and  Significant
Estimates".

                                       20


Cash payments  made in 2002 for  restructuring  activities  related to the March
2001 restructuring plan were $2.7 million.

We did not have any additional  restructurings  in 2002. During 2002, we did not
have any changes in estimates related to 2001  restructurings  that affected the
Statement of Operations.

Restructuring - October 18, 2001

Due to a  continued  decline  in  market  conditions,  we  implemented  a second
restructuring  plan in the fourth  quarter of 2001 to reduce our operating  cost
structure.  This  restructuring  plan included the termination of 341 employees,
the  consolidation  of additional  excess  facilities,  and the  curtailment  of
additional research and development  projects. As a result, we recorded a second
restructuring charge of $175.3 million in the fourth quarter of 2001.

The  following  summarizes  the  activity  in  the  October  2001  restructuring
liability:

We have completed the restructuring  activities contemplated in the October 2001
plan,  but have not yet disposed of all of our surplus leased  facilities.  Upon
the final  disposition  of our surplus leased  facilities,  we expect to achieve
annualized  savings  of  approximately  $67.6  million in cost of  revenues  and
operating  expenses  based  on the  expenditure  levels  at  the  time  of  this
restructuring.

Restructuring - March 26, 2001

In the first quarter of 2001, we implemented a restructuring plan in response to
the decline in demand for our networking  products and  consequently  recorded a
restructuring  charge of $19.9  million.  The  restructuring  plan  included the
involuntary  termination  of 223 employees  across all business  functions,  the
consolidation  of a number of facilities and the curtailment of certain research
and development projects.

The following summarizes the activity in the March 2001 restructuring liability:

We completed the restructuring activities contemplated in the March 2001 plan by
June 30, 2002 and achieved  annualized savings of approximately $28.2 million in
cost of revenues and operating  expenses based on the expenditure  levels at the
time of this restructuring.

During  the first  six  months of fiscal  2002,  we made cash  payments  of $2.8
million in connection with the March restructuring.  The remaining restructuring
liability of $1.4 million at June 30, 2002 related  primarily to facility  lease
payments,  net of estimated  sublease  revenues,  and was  classified as accrued
liabilities on the balance sheet.  We do not expect this  restructuring  to have
any impact on our Statement of Operations in the future.

         Amortization  of Goodwill  and  Impairment  of Goodwill  and  Purchased
         Intangibles

We adopted the  Statement of Financial  Accounting  Standard No. 142 (SFAS 142),
"Goodwill and Other Intangible  Assets" on a prospective  basis at the beginning
of 2002 and stopped  amortizing  goodwill in accordance  with the  provisions of
SFAS 142. The impact of not amortizing goodwill on the net income and net income
per share for 2001 and 2000 is provided in Note 1 to the Consolidated  Financial
Statements.

In  conjunction  with  the   implementation   of  SFAS  142,  we  completed  the
transitional  impairment  test as of the beginning of 2002 and determined that a
transitional  impairment  charge would not be required.  We also  completed  our
annual  impairment  test in  December  2002 and  determined  that  there  was no
impairment of goodwill.

Amortization  of goodwill  increased to $44.0 million in 2001 from $36.4 million
in 2000  primarily as a result of the goodwill  recorded in connection  with the
Malleable and Datum acquisitions, which were completed in mid 2000.

During the second quarter of 2001, we  discontinued  further  development of the
technology acquired in the purchase of Malleable.  We did not expect to have any
future cash flows related to the Malleable assets and had no alternative use for
the technology. Accordingly, we recorded an impairment charge of $189.0 million,
equal to the remaining net book value of goodwill and intangible  assets related
to  Malleable.  As a  result,  there  was no  remaining  Malleable  goodwill  or
intangibles to amortize in the second half of 2001.

In the fourth  quarter of 2001,  due to a  continued  decline in current  market
conditions and a delay in the introduction of certain products to the market, we
completed an assessment  of the future  revenue  potential  and estimated  costs
associated  with all  acquired  technologies.  As a result  of this  review,  we
recorded an impairment  charge of $79.3 million related to the acquired goodwill
and intangibles  recognized in the purchase of Datum. The impairment  charge was
calculated by the excess of the carrying  value of assets over the present value
of estimated  future cash flow related to these assets.  The  impairment  charge
reduced the amounts subject to amortization for the remainder of 2001.

                                       22


         Costs of Merger

We did not make any pooling acquisitions, and therefore did not incur any merger
costs in 2002 or 2001.  The $38.0  million of merger costs that were incurred in
2000 related to five pooling  acquisitions and consisted primarily of investment
banking and other professional fees.

         In Process Research and Development ("IPR&D")

We did not make any  acquisitions  that were  accounted  for using the  purchase
method in 2002 or 2001,  and therefore did not incur any IPR&D charges in either
of those years.

The $38.2 million  expensed to in process research and development in 2000 arose
from the acquisitions of Malleable and Datum.

We calculated the charge for IPR&D related to Malleable and Datum by determining
the fair  value of the  existing  products  as well as the  technology  that was
currently  under  development  using  the  income  approach.  Under  the  income
approach,  expected future  after-tax cash flows from each of the projects under
development  are  estimated  and  discounted  to their net  present  value at an
appropriate  risk-adjusted  rate of return.  Revenues  were  estimated  based on
relevant market size and growth factors,  expected  industry trends,  individual
product  sales  cycles  and the  estimated  life of  each  product's  underlying
technology.  Estimated operating expenses,  income taxes and charges for the use
of  contributory  assets were  deducted  from  estimated  revenues to  determine
estimated  after-tax cash flows for each project.  These  projected  future cash
flows were further adjusted for the value contributed by any core technology and
development efforts expected to be completed post acquisition.

These forecasted cash flows were then discounted based on rates derived from our
weighted average cost of capital,  weighted average return on assets and venture
capital rates of return adjusted upward to reflect  additional risks inherent in
the  development  life cycle.  The risk  adjusted  discount  rates used involved
consideration  of the  characteristics  and  applications  of each product,  the
inherent  uncertainties  in  achieving  technological  feasibility,  anticipated
levels of market  acceptance  and  penetration,  market  growth  rates and risks
related  to the impact of  potential  changes in future  target  markets.  After
considering these factors, we determined risk adjusted discount rates of 35% for
Malleable and 30% for Datum.

In  our  opinion,   the  pricing  model  used  for  products  related  to  these
acquisitions were standard within the high-technology industry and the estimated
IPR&D  amounts  so  determined  represented  fair  value and did not  exceed the
amounts that a third party would have paid for these projects.  When we acquired
these  companies,  we did not  expect to  achieve a  material  amount of expense
reduction  or  synergies  as a result of  integrating  the  acquired  in process
technology.  Therefore,  the valuation  assumptions did not include  anticipated
cost savings.

A description of the IPR&D projects acquired is set forth below:

The in process technology acquired from Malleable was planned to detect incoming
voice  channels  and  process  them  using  voice  compression  algorithms.  The
compressed voice was to be converted,  using the appropriate  protocols,  to ATM
cells or IP packets to achieve  higher  channel  density  and  support  multiple
speech compression protocols and different  packetization  requirements.  At the
date of acquisition we estimated  that  Malleable's  technology was 58% complete
and the costs to complete the project to be $4.4 million.

                                       23


The  technology  acquired  from  Datum  is  a  digitally   controlled  amplifier
architecture,  which was designed to increase  base station  system  capacities,
while reducing cost, size and power  consumption of radio networks.  At the date
of  acquisition,  we estimated that Datum's  technology was 59% complete and the
costs to complete the project to be $1.8 million.

The above  estimates  were  determined  by comparing the time and costs spent to
date and the complexity of the technologies achieved to date to the total costs,
time  and  complexities   that  were  expected  to  be  expended  to  bring  the
technologies to completion.

Progress on the technology  acquired from  Malleable was slower than  originally
estimated and as a result,  costs incurred on this project exceeded our original
estimates.  In the second quarter of 2001, we  discontinued  development of this
technology and recorded an impairment  charge related to the Malleable  goodwill
and purchased intangible assets (see "Amortization of Goodwill and Impairment of
Intangibles").

Development of the chip  incorporating  the  technology  acquired from Datum was
completed in the fourth quarter of 2000 and the costs incurred to that date were
in line  with our  initial  expectations.  Since  then,  we have  completed  the
required  firmware  related to this chip and have  extended  development  of the
Datum  technology  to a follow-on  product.  The general  economic  slowdown has
delayed our customers'  introduction of the third  generation base stations into
which we had expected the Datum technology to be  incorporated.  It is currently
uncertain when the Datum products will begin to generate significant revenues.

As a result of the delay in introduction of the third  generation base stations,
we failed to achieve the revenues, net income, and return on investment expected
at the time that the acquisition was completed. We recorded an impairment charge
related to the Datum goodwill and purchased  intangible assets during the fourth
quarter of 2001 (see "Amortization of Goodwill and Impairment of Intangibles").

Net interest and other income declined in 2002 by $8.9 million, or 64%.

Excluding  interest  expense  and  the  amortization  of debt  financing  costs,
interest  and other  income  for 2002 was $17.1  million  as  compared  to $19.0
million in 2001.  While our  interest  income  declined  by  approximately  $5.5
million as a result of a decline of average  yields on our cash,  short term and
long term  investments,  this decline was partially offset by an additional $3.6
million  in  interest  income  from an  overall  increase  in our  average  cash
balances.

Our interest  expense and  amortization  of our debt issuance costs increased to
$12.1  million in 2002,  from $5.0  million  in 2001,  because  our  convertible
subordinated notes were outstanding for the entire year of 2002 compared to less
than five months in 2001.

Our net interest income decreased to $13.9 million in 2001 from $18.9 million in
2000.  While our interest  income  declined by  approximately  $3.2 million as a
result of a decline  of  average  yields on our cash,  short  term and long term
investments,  this decline was offset by an additional  $3.0 million in interest
income from an overall increase in our cash balances. Interest expense increased
by $3.6 million and we incurred $0.6 million in amortized debt issuance costs in
2001 compared to 2000 due to the issuance of our convertible  subordinated notes
in August 2001.  Other income in 2000 included income from an equity interest in
another company of $0.6 million.

We reported a net loss on investments of $11.6 million in 2002, $14.6 million in
2001 and a gain on investments of $58.5 million in 2000.

In  2002,  we  recorded  a $3.7  million  gain on the sale of a  portion  of our
investment  in  Sierra  Wireless,  Inc.,  a  public  company,  as well as  other
investments.  This gain was offset by a $15.3  million  charge to recognize  the
impairment of our investments in non-public  entities.  See "Critical Accounting
Policies and Significant Estimates".

In  2001,  we  recorded  a $2.9  million  gain on the sale of a  portion  of our
investment  in  Sierra  Wireless,  as well as other  investments.  This gain was
offset by a $17.5 million charge to recognize the impairment of our  investments
in  non-public  entities.  See  "Critical  Accounting  Policies and  Significant
Estimates".

In 2000,  gains of $54.4  million and $4.1 million  resulted  from the sale of a
portion of our  investment  in Sierra  Wireless  and our  investment  in Cypress
Semiconductor,  Inc., respectively.  Our investment in Cypress Semiconductor was
received  through  its  acquisition  of IC  Works,  a  company  in  which we had
invested.


Provision for Income Taxes.

Our  annual  effective  tax rate  for the year  ended  December  31,  2002 was a
recovery of 22.5%.  Excluding  the  effects of  non-deductible  amortization  of
purchased intangibles and deferred stock compensation,  and incremental taxes on
foreign earnings, the effective income tax rate for 2001 was a recovery of 24.1%
compared to the statutory tax rate of 35%. Our effective tax rate was lower than
the statutory rate as a result of a valuation allowance provided on deferred tax
assets, where timing of realization is uncertain.

Our  annual  effective  tax rate  for the year  ended  December  31,  2001 was a
recovery of 2.7%.  Excluding the effects of  non-deductible  goodwill,  deferred
stock  compensation  amortization,  impairment  of  purchased  intangibles,  and
incremental  taxes on foreign  earnings,  the effective income tax rate for 2001
was a recovery of 21.7% compared to the statutory tax rate of 35%. Our effective
tax rate was lower than the statutory  rate for the same reason as in 2002.  Our
annual effective tax rate for the year ended December 31, 2000 was an expense of
57.6% compared to a statutory tax rate of 35%. Our increased  effective tax rate
primarily  reflects  the  higher  provision  for income  taxes for our  Canadian
subsidiary  and the  non-tax  deductible  charges  for in process  research  and
development, goodwill amortization,  deferred stock compensation and acquisition
costs  related to  acquisitions  completed  during the year.  These factors were
partially  offset by the utilization of tax losses and other deferred tax assets
for which benefits were previously not recognized.

         Recently issued accounting standards.

In June 2002, the Financial  Accounting  Standards Board (FASB) issued Statement
of  Financial  Accounting  Standard  No. 146 (SFAS 146),  "Accounting  for Costs
Associated  with  Exit or  Disposal  Activities".  SFAS  146  requires  that the
liability for a cost associated with an exit or disposal  activity be recognized
at its fair value when the liability is incurred.  Under  previous  guidance,  a
liability  for certain  exit costs was  recognized  at the date that  management
committed to an exit plan.  As SFAS 146 is  effective  only for exit or disposal
activities  initiated  after  December 31, 2002,  the adoption of this statement
will  not  impact  our  financial  statements  for  2002,  but will  affect  the
accounting  for any  restructurings  initiated  after 2002.  In January 2003, we
announced a third  restructuring  plan, the costs of which will be accounted for
in accordance with SFAS 146.

In  November  2002,  the  FASB  issued  FASB  Interpretation  No.  45 (FIN  45),
"Guarantor's  Accounting and Disclosure  Requirements for Guarantees,  Including
Indirect  Guarantees  of  Indebtedness  of Others".  FIN 45  requires  that upon
issuance of a guarantee,  a guarantor  must  recognize a liability  for the fair
value  of an  obligation  assumed  under  a  guarantee.  FIN  45  also  requires
additional  disclosures  by a  guarantor  in its  interim  and annual  financial
statements  about  the  obligations   associated  with  guarantees  issued.  The
recognition  provisions of FIN 45 will be effective for any guarantees  that are
issued  or  modified   after  December  31,  2002.  We  adopted  the  disclosure
requirements  and  are  currently  evaluating  the  effects  of the  recognition
provisions  of FIN 45;  however,  we do not expect that the adoption will have a
material impact on our results of operations or financial position.

In December 2002, the FASB issued Statement of Financial Accounting Standard No.
148 (SFAS 148),  "Accounting  for  Stock-Based  Compensation  -  Transition  and
Disclosure". SFAS 148 provides alternative methods of transition for a voluntary
change to the fair value based method of  accounting  for  stock-based  employee
compensation.  SFAS 148 also  requires  prominent  disclosure in the "Summary of
Significant Accounting Policies" of both annual and interim financial statements
about the method of accounting for  stock-based  employee  compensation  and the
effect of the method used on reported results.  We adopted SFAS 148 for our 2002
fiscal year end.  Adoption of this  statement  has affected the location of this
disclosure within our Consolidated Financial Statements, but will not impact our
results of operation or  financial  position  unless we change to the fair value
method of accounting for stock-based employee compensation.

Critical Accounting Estimates

         General

Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations is based upon our Consolidated Financial Statements,  which have been
prepared in accordance  with  accounting  principles  generally  accepted in the
United States. The preparation of these financial statements requires us to make
estimates  and  assumptions  that affect the  amounts  reported by us of assets,
liabilities,  revenue and expenses,  and related disclosure of contingent assets
and liabilities.  Management bases its estimates on historical experience and on
various  other  assumptions  that are  reasonable in the  circumstances.  Senior
management  has discussed  the  development,  selection and  disclosure of these
estimates with the Audit  Committee of PMC's Board of Directors.  Actual results
may differ from these estimates under different assumptions or conditions.

Our significant  accounting  policies are outlined in Note 1 to the Consolidated
Financial Statements.  In management's opinion the following critical accounting
policies require the most significant  judgment and involve complex  estimation.
We also have other policies that we consider to be key accounting policies, such
as our policies of revenue  recognition,  including  the deferral of revenues on
sales to major  distributors;  however these policies do not meet the definition
of critical  accounting  estimates as they do not  generally  require us to make
estimates or judgments that are difficult or subjective.

         Restructuring charges  - Facilities

In calculating  the cost to dispose of our excess  facilities we had to estimate
for each  location  the  amount to be paid in lease  termination  payments,  the
future lease and operating  costs to be paid until the lease is terminated,  and
the amount,  if any,  of sublease  revenues.  This  required us to estimate  the
timing and costs of each lease to be terminated,  the amount of operating  costs
for the affected  facilities,  and the timing and rate at which we might be able
to sublease  each site.  To form our  estimates  for these costs we performed an
assessment  of  the  affected  facilities  and  considered  the  current  market
conditions for each site.

During 2001, we recorded total charges of $155 million for the  restructuring of
excess facilities as part of restructuring plans, which was approximately 53% of
the estimated total future  operating cost and lease obligation for those sites.
As at  the  end of  2002,  the  remaining  restructuring  accrual  is 50% of the
estimated total future  operating costs and lease  obligations for the remaining
sites. To the best of our knowledge,  this estimate remains  sufficient to cover
anticipated  settlement  costs.  However,  our  assumptions  on either the lease
termination  payments,  operating  costs  until  terminated,  or the amounts and
timing of  offsetting  sublease  revenues may turn out to be  incorrect  and our
actual cost may be materially different from our estimates.

         Inventory

We periodically  compare our inventory  levels to sales forecasts for the future
twelve months on a part-by-part  basis and record a charge for inventory on hand
in excess of the  estimated  twelve-month  demand.  In 2002,  our  inventory  of
networking  products  exceeded  estimated  12-month  demand by $4 million and we
recorded a charge of that amount. If future demand for our products continues to
decline, we may have to take an additional write-down of inventory.

                                       27


         Income Taxes

We have  incurred  losses and other  costs that can be  applied  against  future
taxable  earnings  to reduce  our tax  liability  on those  earnings.  As we are
uncertain of realizing the future benefit of those losses and  expenditures,  we
have taken a valuation  allowance  against all domestic  deferred tax assets and
recorded  only  deferred  tax assets  that can be applied in  currently  taxable
foreign jurisdictions.

         Investment in Non-Public Entities

We have invested in non-public  companies and in venture capital funds, which we
review  periodically to determine if there has been a  non-temporary  decline in
the market value of those  investments  below our carrying value. Our assessment
of impairment  in carrying  value is based on the market value trends of similar
public companies,  the current business  performance of the entities in which we
have invested,  and if available,  the estimated  future market potential of the
companies and venture  funds.  We recorded an impairment of our  investments  in
non-public  entities  of $15.3  million in the fourth  quarter of 2002.  When we
perform future assessments of these investments,  a further decline in the value
of these  companies  and venture  funds may require us to  recognize  additional
impairment on the remaining $7.1 million investment.

         Valuation  of  Long-Lived  Assets  Including   Goodwill  and  Purchased
         Intangible Assets

We review property and equipment,  goodwill and purchased  intangible assets for
impairment on an annual basis and between annual tests when events or changes in
circumstances  indicate the carrying  value of an asset may not be  recoverable.
Such events may include a change in business strategy,  significant  declines in
our sales forecast or prolonged negative industry or economic trends.

Our asset  impairment  review assesses the fair value of the assets based on the
future cash flows the assets are expected to generate. For long-lived assets, an
impairment  loss is recognized  when  estimated  undiscounted  future cash flows
expected to result  from the use of the asset plus net  proceeds  expected  from
disposition of the asset (if any) are less than the carrying value of the asset.
For  goodwill,  an  impairment  loss will be  recorded  to the  extent  than the
carrying value of the goodwill exceeds its implied fair value.

In 2002,  we  recorded  an  impairment  charge of $1.8  million  reflecting  the
reduction in fair value of a product tester.  We did not identify any impairment
to goodwill or purchased intangibles during our annual assessment in 2002.


Business Outlook

Our annual networking  revenues are impacted by short and longer-term  trends in
the demand for the networking  equipment that  incorporate our products.  Future
demand for our  customers'  products  is in turn  affected by the plans of their
customers.  Our customers' demand for our products is also impacted by levels of
inventories of our parts held by them or their supply chain partners.

In 2001 and 2002,  many of our  customers  experienced  significant  declines in
demand  for their  products,  and  accumulated  significant  inventories  of our
products  that exceed the amounts  required to meet current  production  levels.
Consequently,  the demand for our products  declined in 2001 from  approximately
$120  million in the first  quarter to  approximately  $47 million in the fourth
quarter. Quarterly revenues during 2002 ranged from $50 million to $60 million.

                                       28


Because the level of demand for the networking equipment that our customers sell
depends  upon global  economic  conditions,  it is difficult to predict when end
market  demand for our  products  will  improve.  However,  we believe  that our
customers may consume much of their inventories of some of our older products in
2003 and begin to  purchase  more of our  products as their  inventories  become
depleted.

We expect our  networking  revenues  for the first  quarter of 2003 to  increase
slightly from the fourth  quarter of 2002.  Beyond the first quarter of 2003, we
anticipate revenues will vary depending on changes in the demand environment and
customer component inventory levels. We do not anticipate any meaningful revenue
from our  non-networking  products  in the future as the single  product in this
revenue category has reached end-of-life.

We anticipate our gross margins will be in the high 50% to low 60% range in 2003
but could vary significantly depending on the volumes and mix of products sold.

Excluding the impact of any  restructuring  activities that are reflected in R&D
and MG&A expenses,  we expect these costs to decline in 2003 as compared to 2002
due to our cost cutting initiatives, including the restructuring we announced in
January  2003.  We  anticipate  that  interest  and other  income  will  decline
significantly  in 2003  compared to 2002 because we expect to earn lower average
yields on our cash  balances  and  expect to  consume  cash  throughout  2003 to
primarily meet restructuring obligations accrued as current liabilities.


Liquidity and Capital Resources

Our  principal  sources of liquidity  at December  31, 2002 were our cash,  cash
equivalents and short-term  investments of $416.7  million.  We also held $148.9
million of investments in bonds and notes with maturities  ranging from 1 to 2.5
years. The aggregate cash and investments of $565.6 million at December 31, 2002
was $16.2  million  lower than it was on  December  31, 2001 and  included  $5.3
million  of  restricted  cash  (see  note  6  to  the   Consolidated   Financial
Statements).

In 2002, we used $19.7 million of cash for  operating  activities,  $3.1 million
for purchases of property and  equipment  and $2.3  million,  net of proceeds on
sales,  for  other  investments.  We  generated  $9.4  million  of cash  through
financing activities, primarily through the issuance of common stock.

We invested  our  portfolio  of short and long term bonds and notes in corporate
and US and Canadian  government  securities having an S&P, Moody's or equivalent
rating of A or better.  All of our bond and note investments mature in less than
2.5 years.  We invest these  capital  resources  primarily for  preservation  of
capital and secondarily for yield.

We have a line of credit with a bank that allows us to borrow up to $5.3 million
at the bank's  alternate  base rate as long as the  Company  maintains  eligible
investments  with the bank in an amount equal to its  drawings.  At December 31,
2002 we had committed  all of this facility  under letters of credit as security
for office  leases.  These letters of credit renew  automatically  each year and
expire in 2011.

                                       29



We have commitments made up of the following:

Approximately  $260  million  of  the  minimum  rental  payments  and  estimated
operating  costs  identified  in the table above relate to operating  leases for
vacant and excess office facilities. We are currently negotiating settlements of
these leases and may incur significant  related cash expenditures.  We expect to
expend the  majority of the $129.5  million we have  accrued  for  restructuring
costs in settlement of these obligations in 2003. See Note 3 to the Consolidated
Financial  Statements for additional  information  regarding  restructuring  and
other costs.

We  participate  in four  professionally  managed  venture  funds that invest in
early-stage private technology companies in markets of strategic interest to us.
From time to time these funds request additional capital for private placements.
We have committed to invest an additional $38.1 million into these funds,  which
may be requested by the fund managers at any time over the next seven years.

We have not entered into any  derivative  contracts  other than our  convertible
notes and  through our stock  option  plans,  and we have not  entered  into any
synthetic leases.

We believe  that  existing  sources of  liquidity  will  satisfy  our  projected
restructuring,  operating,  working capital,  venture investing,  debt interest,
capital expenditure and wafer deposit  requirements  through the end of 2003. We
expect to spend approximately $8 million on new capital additions during 2003.


FACTORS THAT YOU SHOULD CONSIDER BEFORE INVESTING IN PMC-SIERRA

Our  company is  subject  to a number of risks - some are normal to the  fabless
networking  semiconductor  industry,  some  are the  same or  similar  to  those
disclosed in previous SEC  filings,  and some may be present in the future.  You
should carefully  consider all of these risks and the other  information in this
report  before  investing in PMC. The fact that certain risks are endemic to the
industry does not lessen the significance of the risk.

As a result of these  risks,  our  business,  financial  condition  or operating
results could be  materially  adversely  affected.  This could cause the trading
price  of our  securities  to  decline,  and  you may  lose  part or all of your
investment.

We are  subject  to rapid  changes in demand for our  products  due to  customer
inventory levels,  production  schedules,  fluctuations in demand for networking
equipment and our customer concentration.

                                       30


As a result of these factors,  we have very limited  revenue  visibility and the
rate by which revenues are booked and shipped  within the same reporting  period
is typically  volatile.  In  addition,  our net bookings can vary sharply up and
down within a quarter.

         Our  revenues  have  declined  due to reduced  demand in the markets we
         serve, and may decline further in 2003.

Several of our customers'  clients have reported lower than expected  demand for
their  services or products,  which has resulted in poor  operating  results and
difficulty in accessing the capital needed to build their networks or survive to
profitability. Many of these companies are facing increased competition and have
either  filed  for  bankruptcy  or may  become  insolvent  in the  near  future.
Concurrently,  many of our  customers'  more  viable  network  service  provider
clients have accumulated significant debt loads to finance capital projects that
have yet to generate significant  positive cash flows. In addition,  most of our
customers'  clients have  announced a shift in  forecasted  expenditures  on the
equipment our customers sell,  which may generate  financial return in a shorter
time horizon.  This  equipment to which they shift may not  incorporate,  or may
incorporate fewer, of our products.

In  response to the actual and  anticipated  declines  in  networking  equipment
demand,  many of our customers and their contract  manufacturers have undertaken
initiatives  to   significantly   reduce   expenditures   and  excess  component
inventories.  Many  platforms  in which  our  products  are  designed  have been
cancelled as our customers cancel or restructure product development initiatives
or as  venture-financed  startup  companies fail. Our revenues may be materially
and adversely impacted in 2003 if these conditions continue or worsen.

Our  customers'  actions have  materially  and adversely  impacted our revenues,
reduced our  visibility  of future  revenue  streams,  caused an increase in our
inventory levels, and made a portion of our inventory  obsolete.  As most of our
costs  are fixed in the  short  term,  a  further  reduction  in demand  for our
products may cause a further decline in our gross and net margins.

While we  believe  that our  customers  and  their  contract  manufacturers  are
consuming a portion of their  inventory of PMC  products,  we believe that those
inventories,  as well as the weakened demand that our customers are experiencing
for their  products,  may further depress our revenues and profit margins beyond
2002 (see "Business  Outlook" above). We cannot  accurately  predict when demand
for our products will strengthen or how quickly our customers will consume their
inventories of our products.

         Our  customers  may cancel or delay the  purchase of our  products  for
         reasons other than the industry downturn described above.

Many  of  our  customers  have  numerous  product  lines,   numerous   component
requirements  for each product,  sizeable and complex supplier  structures,  and
often engage contract manufacturers to supplement their manufacturing  capacity.
This makes forecasting their production  requirements  difficult and can lead to
an inventory surplus of certain of their components.

Our  customers  often shift  buying  patterns as they manage  inventory  levels,
decide to use competing  products,  are acquired or divested,  market  different
products, or change production schedules.

                                       31


In addition,  we believe that  uncertainty in our customers' end markets and our
customers'  increased focus on cash management has caused our customers to delay
product orders and reduce delivery lead-time  expectations.  We expect this will
increase  the  proportion  of our  revenues in future  periods that will be from
orders  placed and  fulfilled  within the same  period.  This will  decrease our
ability to accurately forecast and may lead to greater fluctuations in operating
results.

         We rely on a few customers for a major portion of our sales, any one of
         which could materially impact our revenues should
         they change their ordering pattern.

We depend on a limited  number of customers for a major portion of our revenues.
Through  direct,  distributor  and  subcontractor  purchases,  Cisco Systems and
Hewlett  Packard each  accounted for more than 10% of our fiscal 2002  revenues.
Both of  these  customers  have  announced  order  shortfalls  for some of their
products.

We do not have  long-term  volume  purchase  commitments  from any of our  major
customers.  Accordingly, our future operating results will continue to depend on
the success of our largest customers and on our ability to sell existing and new
products  to  these  customers  in  significant  quantities.  The  loss of a key
customer,  or a reduction in our sales to any key  customer or our  inability to
attract new  significant  customers  could  materially and adversely  affect our
business, financial condition or results of operations.

         If the current downturn continues,  we may have to add to our inventory
         reserve,  which  would  lead  to a  further  decline  in our  operating
         profits.

As a result of the  industry-wide  reduction in capital  spending and  resulting
significant  decrease  in demand for our  products,  we  determined  that we had
inventory  levels  that  exceeded  our  anticipated  demand over the next twelve
months.  Accordingly,  in 2002 we recorded an inventory write-down of $4 million
related to excess  inventory  on hand.  The  inventory  reserve was based on our
revenue  expectations  through  2003.  If future demand of our products does not
meet  our  expectations,  we may  need  to  take  an  additional  write-down  of
inventory.


We  anticipate  lower  margins on high volume  products,  which could  adversely
affect our profitability.

We expect the average  selling prices of our products to decline as they mature.
Historically,  competition  in the  semiconductor  industry  has driven down the
average  selling  prices of products.  If we price our  products  too high,  our
customers may use a competitor's  product or an in-house  solution.  To maintain
profit  margins,  we must reduce our costs  sufficiently  to offset  declines in
average selling prices, or successfully sell  proportionately  more new products
with higher average  selling  prices.  Yield or other  production  problems,  or
shortages  of supply  may  preclude  us from  lowering  or  maintaining  current
operating costs.

OEMs are  becoming  more  price  conscious  than in the past as a result  of the
industry  downturn,  and as  semiconductors  sourced from third party  suppliers
comprise a greater portion of the total materials cost in OEM equipment. We have
also experienced more aggressive price competition from competitors that wish to
enter into the market segments in which we participate.  These circumstances may
make some of our products less  competitive and we may be forced to decrease our
prices  significantly to win a design.  We may lose design  opportunities or may
experience  overall  declines in gross  margins as a result of  increased  price
competition.

                                       32


In addition,  our networking  products range widely in terms of the margins they
generate.  A change in  product  sales mix could  impact our  operating  results
materially.

Design wins do not translate into near-term  revenues and the timing of revenues
from newly designed products is often uncertain.

We have  announced a number of new products and design wins for existing and new
products.  While some  industry  analysts  may use  design  wins as a metric for
future  revenues,  many design wins have not, nor will not generate any revenues
as customer projects are cancelled or rejected by their end market. In the event
a design win generates revenue, the amount of revenue will vary greatly from one
design win to another. In addition, most  revenue-generating  design wins do not
translate  into near term  revenues.  Most  revenue-generating  design wins take
greater than 2 years to generate meaningful revenue.

Our revenue expectations may include growing sales of newer semiconductors based
on early adoption of those products by customers.  These  expectations would not
be achieved if early sales of new system level  products by our customers do not
increase  over time.  We may  experience  this more with  design wins from early
stage  companies,  who tend to focus on  leading-edge  technologies  that may be
adopted less rapidly in the current  environment by  telecommunications  service
providers.


Our  restructurings  have  curtailed our  resources and may have  insufficiently
addressed market conditions.

We  announced in 2001 plans to  restructure  our  operations  in response to the
decline in demand for our networking products.  The restructuring plans included
a workforce reduction of 564 employees,  consolidation of excess facilities, and
contract  settlement  activities.  As a result of our  restructuring  plans,  we
recorded a charge of $195.2 million in 2001. On January 16th, 2003, we announced
plans to further restructure our operations through a workforce reduction of 175
employees  and the shutdown of four of our research and  development  sites.  We
will record a charge in the first two  quarters  of 2003 of our  estimate of the
costs for the restructuring.

We reduced the work force and consolidated or shut down excess  facilities in an
effort to bring our expenses  into line with our reduced  revenue  expectations.
However,  for  much of  2003,  we do not  expect  that  these  measures  will be
sufficient to offset lower revenues, and as such, we expect to continue to incur
net losses.

While management uses all available  information to estimate these restructuring
costs,  particularly  facilities costs, our accruals may prove to be inadequate.
If our actual sublease revenues or exiting negotiations differ from our original
assumptions,  we may have to record additional  charges,  which could materially
affect our results of operations, financial position and cash flow.

                                       33


Restructuring plans require significant  management  resources to execute and we
may fail to achieve our targeted goals and our expected  annualized  savings. We
may have incorrectly  anticipated the demand for our products,  we may be forced
to  restructure  further  or may incur  further  operating  charges  due to poor
business  conditions  and some of our  product  development  initiatives  may be
delayed due to the reduction in our development resources.

Our revenues may decline if our customers use our competitors'  products instead
of ours, suffer further  reductions in demand for their products or are acquired
or sold.

We are experiencing significantly greater competition from many different market
participants as the market in which we participate matures. In addition,  we are
expanding  into  markets,  such  as  the  wireless  infrastructure  and  generic
microprocessor  markets,  which have  established  incumbents  with  substantial
financial and technological  resources.  We expect fiercer competition than that
which we have traditionally  faced as some of these incumbents derive a majority
of their earnings from these markets.

All of our competitors pose the following threats to us:

         As our customers  design next  generation  systems and select the chips
         for those new systems,  our competitors have an opportunity to convince
         our  customers to use their  products,  which may cause our revenues to
         decline.

We typically face  competition  at the design stage,  where  customers  evaluate
alternative design approaches requiring integrated circuits. Our competitors may
have more  opportunities  to supplant  our products in next  generation  systems
because  of the  shortening  product  life and  design-in  cycles in many of our
customers' products.

In addition, as a result of the industry downturn, and as semiconductors sourced
from third party  suppliers  comprise a greater  portion of the total  materials
cost in OEM equipment,  OEMs are becoming more price conscious than in the past.
We have also experienced  increased price  aggressiveness  from some competitors
that wish to enter  into the  market  segments  in which we  participate.  These
circumstances may make some of our products  price-uncompetitive  or force us to
match low prices.  We may lose design  opportunities  or may experience  overall
declines in gross margins as a result of increased price competition.

The markets for our  products  are  intensely  competitive  and subject to rapid
technological  advancement  in design  tools,  wafer  manufacturing  techniques,
process  tools  and  alternate  networking  technologies.  We may not be able to
develop new products at competitive  pricing and performance  levels. Even if we
are able to do so, we may not complete a new product and  introduce it to market
in a timely  manner.  Our customers may  substitute use of our products in their
next generation equipment with those of current or future competitors.

         Increasing  competition  in our industry will make it more difficult to
         achieve design wins.

We face  significant  competition  from three major  fronts.  First,  we compete
against  established  peer-group  semiconductor  companies  that  focus  on  the
communications  semiconductor  business.  These companies include Agere Systems,
Applied  Micro  Circuits  Corporation,   Broadcom,  Exar  Corporation,  Conexant
Systems,  Marvell Technology Group,  Multilink Technology  Corporation,  Silicon
Image, Transwitch and Vitesse Semiconductor.  These companies are well financed,
have  significant   communications   semiconductor   technology   assets,   have
established  sales  channels,  and are  dependent  on the  market  in  which  we
participate for the bulk of their revenues.

                                       34


Other  competitors  include  major  domestic  and  international   semiconductor
companies,  such  as  Agilent,  Cypress  Semiconductor,  Intel,  IBM,  Infineon,
Integrated  Device  Technology,  Maxim  Integrated  Products,  Motorola,  Nortel
Networks, and Texas Instruments. These companies are concentrating an increasing
amount of their  substantial  financial  and other  resources  on the markets in
which we participate. This represents a serious competitive threat to us.

Emerging  venture-backed  companies also provide significant  competition in our
segment of the semiconductor  market.  These companies tend to focus on specific
portions  of our broad  range of  products  and in the  aggregate,  represent  a
significant  threat to our product lines.  In addition,  these  companies  could
introduce  disruptive  technologies  that may make our technologies and products
obsolete.

Over the next few years,  we expect  additional  competitors,  some of which may
also have greater  financial and other  resources,  to enter the market with new
products. These companies,  individually or collectively, could represent future
competition for many design wins, and subsequent product sales.

         We must often redesign our products to meet evolving industry standards
         and customer specifications,  which may prevent or delay future revenue
         growth.

We sell products to a market whose  characteristics  include  evolving  industry
standards, product obsolescence,  and new manufacturing and design technologies.
Many of the  standards  and  protocols  for our products are based on high-speed
networking  technologies that have not been widely adopted or ratified by one or
more of the standard-setting  bodies in our customers'  industry.  Our customers
often delay or alter their design demands during this standard-setting  process.
In  response,  we must  redesign our  products to suit these  changing  demands.
Redesign usually delays the production of our products.  Our products may become
obsolete during these delays.

         Since many of the  products  we  develop  do not reach full  production
         sales  volumes  for a number of years,  we may  incorrectly  anticipate
         market  demand and develop  products  that achieve  little or no market
         acceptance.

Our   products   generally   take   between  18  and  24  months  from   initial
conceptualization  to  development  of a viable  prototype,  and another 6 to 18
months to be designed into our  customers'  equipment and into  production.  Our
products often must be redesigned because manufacturing yields on prototypes are
unacceptable  or customers  redefine  their  products to meet changing  industry
standards or customer  specifications.  As a result,  we develop  products  many
years before volume  production and may  inaccurately  anticipate our customers'
needs.

Our strategy includes  broadening our business into the Enterprise,  Storage and
Consumer  markets.  We may not be successful in achieving  significant  sales in
these new markets.

The Enterprise,  Storage and Consumer markets are already addressed by incumbent
suppliers  which  have  established  relationships  with  customers.  We  may be
unsuccessful in displacing these suppliers, or having our products designed into
products  for  different   market  needs.  We  may  incur  increased   research,
development and sales costs to address these new markets.

                                       35



We are  exposed  to the  credit  risk of some of our  customers  and we may have
difficulty collecting receivables from customers based in foreign countries.

Many of our customers  employ contract  manufacturers  to produce their products
and manage their  inventories.  Many of these contract  manufacturers  represent
greater credit risk than our networking  equipment  customers,  who generally do
not guarantee our credit receivables related to their contract manufacturers.

In addition,  international debt rating agencies have  significantly  downgraded
the bond ratings on a number of our larger  customers,  which had  traditionally
been considered financially stable. Should these companies enter into bankruptcy
proceedings or breach their debt covenants, our significant accounts receivables
with these companies could be jeopardized.


The complexity of our products could result in unforeseen delays or expenses and
in  undetected  defects  or  bugs,  which  could  adversely  affect  the  market
acceptance of new products and damage our reputation with current or prospective
customers.

Although we, or our customers and our  suppliers  rigorously  test our products,
our highly complex  products  regularly  contain defects or bugs. We have in the
past experienced,  and may in the future experience,  these defects and bugs. If
any of our products  contain  defects or bugs, or have  reliability,  quality or
compatibility problems that are significant to our customers, our reputation may
be damaged  and  customers  may be  reluctant  to buy our  products.  This could
materially  and  adversely  affect our ability to retain  existing  customers or
attract new  customers.  In addition,  these defects or bugs could  interrupt or
delay sales to our customers.

We may have to invest  significant  capital  and other  resources  to  alleviate
problems with our products.  If any of these  problems are not found until after
we have commenced commercial  production of a new product, we may be required to
incur  additional  development  costs and product recall,  repair or replacement
costs.  These  problems may also result in claims against us by our customers or
others. In addition, these problems may divert our technical and other resources
from other development efforts.  Moreover, we would likely lose, or experience a
delay in, market  acceptance of the affected  product or products,  and we could
lose credibility with our current and prospective customers.


We may be  unsuccessful in  transitioning  the design of our new products to new
manufacturing processes.

Many of our new  products are  designed to take  advantage of new  manufacturing
processes offering smaller manufacturing geometries as they become available, as
the smaller geometry  products can provide a product with improved features such
as lower power requirements,  more functionality and lower cost. We believe that
the  transition  of our  products to smaller  geometries  is critical  for us to
remain  competitive.  We could  experience  difficulties  in migrating to future
geometries or  manufacturing  processes,  which would result in the delay of the
production  of our  products.  Our  products  may become  obsolete  during these
delays, or allow  competitors' parts to be chosen by customers during the design
process.


Our  business   strategy   contemplates   acquisition  of  other   companies  or
technologies, which could adversely affect our operating performance.

                                       36


Acquiring products, technologies or businesses from third parties is part of our
business  strategy.  Management may be diverted from our  operations  while they
identify and negotiate these  acquisitions and integrate an acquired entity into
our operations. Also, we may be forced to develop expertise outside our existing
businesses, and replace key personnel who leave due to an acquisition.

An acquisition could absorb  substantial cash resources,  require us to incur or
assume debt obligations, or issue additional equity. If we issue more equity, we
may  dilute  our common  stock  with  securities  that have an equal or a senior
interest.

Acquired entities also may have unknown liabilities, and the combined entity may
not achieve the results that were anticipated at the time of the acquisition.

The timing of revenues from newly designed  products is often uncertain.  In the
past,  we have had to  redesign  products  that we acquired  when  buying  other
businesses, resulting in increased expenses and delayed revenues. This may occur
in the future as we commercialize the new products resulting from acquisitions.

We participate in funds that invest in early-stage private technology  companies
to gain  access to  emerging  technologies.  These  companies  possess  unproven
technologies  and our  investments  may or may not yield  positive  returns.  We
currently have commitments to invest $38.1 million in such funds. In addition to
consuming  significant  amounts of cash, these investments are risky because the
technologies    that   these    companies   are   developing   may   not   reach
commercialization.  We may record an impairment  charge to our operating results
should we determine  that these funds have incurred a  non-temporary  decline in
value.


The loss of personnel could preclude us from designing new products.

To succeed,  we must retain and hire technical  personnel  highly skilled at the
design and test functions needed to develop high-speed  networking  products and
related software. The competition for such employees is intense.

We do not have employment agreements in place with many of our key personnel. As
employee incentives,  we issue common stock options that generally have exercise
prices at the market value at the time of grant and that are subject to vesting.
Recently, our stock price has declined substantially. The stock options we grant
to employees  are effective as retention  incentives  only if they have economic
value.

Our recent restructurings have significantly reduced the number of our technical
employees. We may experience customer  dissatisfaction as a result of delayed or
cancelled product development initiatives.


We may not be  able  to meet  customer  demand  for  our  products  if we do not
accurately  predict demand or if we fail to secure adequate wafer fabrication or
assembly capacity.

                                       37


We currently  do not have the ability to  accurately  predict what  products our
customers will need in the future.  Anticipating demand is difficult because our
customers  face  volatile  pricing  and  demand  for their  end-user  networking
equipment,  our  customers are focusing  more on cash  preservation  and tighter
inventory  management,  and  because we supply a large  number of  products to a
variety of customers and contract manufacturers who have many equipment programs
for which they purchase our products.  Our customers are  frequently  requesting
shipment  of our  products  earlier  than our normal  lead  times.  If we do not
accurately  predict what mix of products our customers may order,  we may not be
able to meet our  customers'  demand  in a timely  manner or we may be left with
unwanted inventory.

A shortage in supply  could  adversely  impact our  ability to satisfy  customer
demand,  which could adversely affect our customer  relationships along with our
current and future operating results.

         We rely on  limited  sources  of wafer  fabrication,  the loss of which
         could delay and limit our product shipments.

We do not own or operate a wafer fabrication  facility.  Three outside foundries
supply greater than 90% of our semiconductor  device  requirements.  Our foundry
suppliers also produce products for themselves and other companies. In addition,
we may not have access to adequate capacity or certain process technologies.  We
have less control over delivery schedules,  manufacturing  yields and costs than
competitors with their own fabrication  facilities.  If the foundries we use are
unable or unwilling to manufacture our products in required volumes, we may have
to identify and qualify  acceptable  additional or alternative  foundries.  This
qualification  process  could  take  six  months  or  longer.  We may  not  find
sufficient   capacity  quickly  enough,  if  ever,  to  satisfy  our  production
requirements.

Some  companies  that supply our customers are similarly  dependent on a limited
number of suppliers to produce their products.  These other companies'  products
may be designed into the same  networking  equipment into which our products are
designed.  Our order levels could be reduced  materially if these  companies are
unable to access sufficient  production  capacity to produce in volumes demanded
by our  customers  because  our  customers  may be  forced  to slow down or halt
production on the equipment into which our products are designed.

         We depend on third  parties in Asia for  assembly of our  semiconductor
         products that could delay and limit our product shipments.

Sub-assemblers in Asia assemble all of our semiconductor  products. Raw material
shortages, political and social instability, assembly house service disruptions,
currency  fluctuations,  or other  circumstances in the region could force us to
seek additional or alternative sources of supply or assembly. This could lead to
supply  constraints or product  delivery delays that, in turn, may result in the
loss of  revenues.  We have  less  control  over  delivery  schedules,  assembly
processes,  quality  assurances and costs than competitors that do not outsource
these tasks.

         We depend on a limited number of design software suppliers, the loss of
         which could impede our product development.

A limited  number of  suppliers  provide  the  computer  aided  design,  or CAD,
software  we  use  to  design  our  products.   Factors   affecting  the  price,
availability or technical  capability of these products could affect our ability
to access  appropriate CAD tools for the development of highly complex products.
In  particular,  the CAD  software  industry  has been the subject of  extensive
intellectual  property rights litigation,  the results of which could materially
change the  pricing  and nature of the  software  we use.  We also have  limited
control over whether our software  suppliers will be able to overcome  technical
barriers in time to fulfill our needs.

                                       38



We are subject to the risks of conducting  business outside the United States to
a greater  extent than  companies  that operate their  businesses  mostly in the
United States,  which may impair our sales,  development or manufacturing of our
products.

We are subject to the risks of conducting  business outside the United States to
a greater  extent  than most  companies  because,  in  addition  to selling  our
products in a number of  countries,  a  significant  portion of our research and
development and manufacturing is conducted outside the United States.

The geographic  diversity of our business operations could hinder our ability to
coordinate design and sales activities.  If we are unable to develop systems and
communication  processes  to support  our  geographic  diversity,  we may suffer
product development delays or strained customer relationships.

         We may lose our  ability  to design or  produce  products,  could  face
         additional  unforeseen  costs or could lose access to key  customers if
         any of the nations in which we conduct  business  impose trade barriers
         or new communications standards.

We may have difficulty obtaining export licenses for certain technology produced
for us outside  the  United  States.  If a foreign  country  imposes  new taxes,
tariffs,  quotas, and other trade barriers and restrictions or the United States
and a  foreign  country  develop  hostilities  or  change  diplomatic  and trade
relationships,  we may not be able to continue  manufacturing or sub-assembly of
our  products in that country and may have fewer sales in that  country.  We may
also have fewer sales in a country that imposes new communications  standards or
technologies.  This could inhibit our ability to meet our customers'  demand for
our products and lower our revenues.

         If foreign exchange rates fluctuate  significantly,  our  profitability
         may decline.

We are exposed to foreign currency rate fluctuations  because a significant part
of our development,  test, marketing and administrative costs are denominated in
Canadian  dollars,  and our  selling  costs  are  denominated  in a  variety  of
currencies  around  the world.  While we have  adopted a foreign  currency  risk
management  policy,  which is  intended  to reduce  the  effects  of  short-term
fluctuations,  our policy may not be effective and it does not address long-term
fluctuations.

In  addition,  while  all  of our  sales  are  denominated  in US  dollars,  our
customers'  products  are sold  worldwide.  Any  further  decline  in the  world
networking  markets could seriously  depress our customers' order levels for our
products.  This effect could be exacerbated if fluctuations in currency exchange
rates decrease the demand for our customers' products.

From time to time, we become  defendants in legal proceedings about which we are
unable to assess our  exposure and which could  become  significant  liabilities
upon judgment.

                                       39


We become  defendants in legal  proceedings from time to time.  Companies in our
industry have been subject to claims related to patent  infringement and product
liability,  as well  as  contract  and  personal  claims.  We may not be able to
accurately  assess  the risk  related  to these  suits,  and we may be unable to
accurately  assess  our  level of  exposure.  These  proceedings  may  result in
material  charges to our  operating  results in the  future if our  exposure  is
material and if our ability to assess our exposure becomes clearer.


If we cannot protect our proprietary  technology,  we may not be able to prevent
competitors  from copying our technology  and selling  similar  products,  which
would harm our revenues.

To compete effectively,  we must protect our proprietary information. We rely on
a  combination   of  patents,   trademarks,   copyrights,   trade  secret  laws,
confidentiality   procedures   and   licensing   arrangements   to  protect  our
intellectual  property  rights.  We hold  several  patents  and have a number of
pending patent applications.

We might not succeed in attaining patents from any of our pending  applications.
Even if we are awarded patents,  they may not provide any meaningful  protection
or  commercial  advantage  to us,  as they  may not be of  sufficient  scope  or
strength,  or may not be issued in all countries where our products can be sold.
In addition, our competitors may be able to design around our patents.

We develop,  manufacture and sell our products in Asian and other countries that
may not protect our products or intellectual  property rights to the same extent
as the laws of the  United  States.  This  makes  piracy of our  technology  and
products more likely.  Steps we take to protect our proprietary  information may
not be  adequate  to  prevent  theft  of our  technology.  We may not be able to
prevent our competitors  from  independently  developing  technologies  that are
similar to or better than ours.


Our products employ  technology  that may infringe on the proprietary  rights of
third parties, which may expose us to litigation and prevent us from selling our
products.

Vigorous  protection and pursuit of  intellectual  property  rights or positions
characterize  the  semiconductor  industry.  This often results in expensive and
lengthy  litigation.  We,  and our  customers  or  suppliers,  may be accused of
infringing  on  patents or other  intellectual  property  rights  owned by third
parties.  This has  happened in the past.  An adverse  result in any  litigation
could force us to pay substantial damages, stop manufacturing, using and selling
the infringing products,  spend significant resources to develop  non-infringing
technology,  discontinue  using  certain  processes  or obtain  licenses  to the
infringing technology. In addition, we may not be able to develop non-infringing
technology,  nor might we be able to find  appropriate  licenses  on  reasonable
terms.

Patent  disputes  in  the  semiconductor  industry  are  often  settled  through
cross-licensing  arrangements.  Because we currently  do not have a  substantial
portfolio of patents compared to our larger  competitors,  we may not be able to
settle  an  alleged  patent   infringement   claim  through  a   cross-licensing
arrangement.  We are  therefore  more exposed to third party claims than some of
our larger competitors and customers.

In the past,  our customers  have been required to obtain  licenses from and pay
royalties  to  third  parties  for  the  sale  of  systems   incorporating   our
semiconductor devices. Customers may also make claims against us with respect to
infringement.

                                       40


Furthermore,  we may initiate  claims or  litigation  against  third parties for
infringing  our  proprietary   rights  or  to  establish  the  validity  of  our
proprietary  rights.  This could  consume  significant  resources and divert the
efforts  of  our  technical  and   management   personnel,   regardless  of  the
litigation's outcome.


We have  significantly  increased  our debt  level  as a  result  of the sale of
convertible subordinated notes.

On August 6, 2001,  we raised $275 million  through the issuance of  convertible
subordinated notes. As a result, our interest payment obligations have increased
substantially.  The  degree  to  which we are  leveraged  could  materially  and
adversely   affect  our  ability  to  obtain   financing  for  working  capital,
acquisitions  or other  purposes and could make us more  vulnerable  to industry
downturns  and  competitive  pressures.  Our  ability  to meet our debt  service
obligations will be dependent upon our future performance, which will be subject
to financial, business and other factors affecting our operations, many of which
are beyond our  control.  On August 15,  2006,  we are obliged to repay the full
remaining  principal  amount of the notes that have not been  converted into our
common stock.


Securities we issue to fund our operations could dilute your ownership.

We may decide to raise additional funds through public or private debt or equity
financing  to  fund  our  operations.  If  we  raise  funds  by  issuing  equity
securities, the percentage ownership of current stockholders will be reduced and
the new equity  securities may have priority rights to your  investment.  We may
not obtain sufficient financing on terms that are favorable to you or us. We may
delay,  limit or eliminate  some or all of our proposed  operations  if adequate
funds are not available.


Our stock price has been and may continue to be volatile.

In the past, our common stock price has fluctuated significantly. In particular,
our stock price declined  significantly in the context of announcements  made by
us and other  semiconductor  suppliers of reduced revenue  expectations and of a
general  slowdown  in  the  markets  we  serve.  Given  these  general  economic
conditions and the reduced demand for our products that we have experienced,  we
expect that our stock price will continue to be volatile.

In addition,  fluctuations in our stock price and our price-to-earnings multiple
may have made our stock attractive to momentum,  hedge or day-trading  investors
who  often  shift  funds  into and out of  stocks  rapidly,  exacerbating  price
fluctuations in either direction particularly when viewed on a quarterly basis.

Securities class action  litigation has often been instituted  against a company
following  periods  of  volatility  and  decline  in the  market  price of their
securities. If instituted against us, regardless of the outcome, such litigation
could result in substantial  costs and diversion of our  management's  attention
and resources  and have a material  adverse  effect on our  business,  financial
condition  and  operating  results.  We could  be  required  to pay  substantial
damages, including punitive damages, if we were to lose such a lawsuit.

                                       41



Provisions  in our charter  documents  and  Delaware  law and our  adoption of a
stockholder  rights  plan may delay or prevent  acquisition  of us,  which could
decrease the value of our common stock.

Our certificate of incorporation and bylaws and Delaware law contain  provisions
that could make it harder for a third party to acquire us without the consent of
our board of directors.  Delaware law also imposes some  restrictions on mergers
and other business  combinations between us and any holder of 15% or more of our
outstanding  common stock. In addition,  our board of directors has the right to
issue  preferred  stock  without  stockholder  approval,  which could be used to
dilute the stock ownership of a potential hostile acquirer.  Although we believe
these provisions of our certificate of incorporation and bylaws and Delaware law
and our  stockholder  rights plan will provide for an  opportunity  to receive a
higher bid by  requiring  potential  acquirers  to  negotiate  with our board of
directors, these provisions apply even if the offer may be considered beneficial
by some stockholders.

Our board of directors adopted a stockholder  rights plan,  pursuant to which we
declared and paid a dividend of one right for each share of common stock held by
stockholders  of record as of May 25, 2001.  Unless  redeemed by us prior to the
time the rights are exercised, upon the occurrence of certain events, the rights
will  entitle  the  holders  to  receive  upon  exercise  thereof  shares of our
preferred stock, or shares of an acquiring entity, having a value equal to twice
the  then-current  exercise price of the right. The issuance of the rights could
have the effect of delaying or preventing a change in control of us.



Item 7a.  Quantitative and Qualitative Disclosures About Market Risk

The following  discussion  regarding  our risk  management  activities  contains
"forward-looking  statements"  that  involve  risks  and  uncertainties.  Actual
results  may differ  materially  from  those  projected  in the  forward-looking
statements.

         Cash Equivalents,  Short-term  Investments and Investments in Bonds and
         Notes:

We  regularly  maintain a short and long term  investment  portfolio  of various
types of government and corporate debt instruments.  Our investments are made in
accordance  with an  investment  policy  approved  by our  Board  of  Directors.
Maturities of these  instruments are less than two and one half years,  with the
majority  being  within one year.  To minimize  credit risk,  we  diversify  our
investments  and select minimum  ratings of P-1 or A by Moody's,  or A-1 or A by
Standard  and  Poor's,   or  equivalent.   We  classify   these   securities  as
held-to-maturity or  available-for-sale  depending on our investment  intention.
Held-to-maturity    investments    are   held   at   amortized    cost,    while
available-for-sale investments are held at fair market value. Available-for-sale
securities  represented  approximately  17% of our  investment  portfolio  as of
December 31, 2002.

Investments  in both fixed rate and floating rate interest  earning  instruments
carry a degree of interest rate risk.  Fixed rate securities may have their fair
market  value  adversely  impacted  because of a rise in interest  rates,  while
floating rate securities may produce less income than expected if interest rates
fall. Due in part to these factors,  our future investment income may fall short
of expectations  because of changes in interest rates or we may suffer losses in
principal  if we were to sell  securities  that have  declined  in market  value
because of changes in interest rates.

                                       42


We do not attempt to reduce or  eliminate  our  exposure  to interest  rate risk
through the use of derivative financial instruments.

Based on a sensitivity  analysis performed on the financial  instruments held at
December 31, 2002 that are sensitive to changes in interest rates, the impact to
the fair value of our investment portfolio by an immediate hypothetical parallel
shift in the yield  curve of plus or minus 50,  100 or 150  basis  points  would
result in a  decline  or  increase  in  portfolio  value of  approximately  $2.5
million, $5 million and $7.4 million respectively.

         Other Investments

Other  investments  at  December  31,  2002  include a  minority  investment  of
approximately  2 million  shares of Sierra  Wireless  Inc.,  a  publicly  traded
company.  The  securities  are recorded on the balance  sheet at fair value with
unrealized gains or losses reported as a separate component of accumulated other
comprehensive income, net of income taxes.

We also periodically  receive  distributions of public company stock as a result
of venture investments.  These shares are usually subject to resale restrictions
and  typically  include a number of shares held in escrow that may or may not be
released at a later date.  At December 31, 2002,  we held  approximately  16,000
shares of Intel  Corporation,  which we received  when Intel  acquired a private
company  in  which  we had an  investment.  It is our  intention  to sell  these
securities in the first quarter of 2003.

Our  public  company  investments  are  subject  to  considerable  market  price
volatility and are additionally  risky due to resale  restrictions.  We may lose
some or all of our investment in these shares.

Our other investments also include numerous  strategic  investments in privately
held  companies or venture  funds that are carried on our balance sheet at cost.
We  expect  to make  additional  investments  like  these in the  future.  These
investments are inherently risky, as they typically are comprised of investments
in companies  and  partnerships  that are still in the  start-up or  development
stages.  The  market  for the  technologies  or  products  that they have  under
development is typically in the early stages, and may never materialize.  In the
fourth  quarter of 2002, we recorded an impairment of our other  investments  of
$15.3 million in response to declining market valuations for these  investments.
We could lose our entire  investment in these companies and  partnerships or may
incur an additional  expense if we determine that the value of these assets have
been further impaired.

         Foreign Currency

We  generate a  significant  portion  of our  revenues  from sales to  customers
located outside of the United States including Canada,  Europe,  the Middle East
and  Asia.  We  are  subject  to  risks  typical  of an  international  business
including,  but not  limited  to,  differing  economic  conditions,  changes  in
political climate, differing tax structures,  other regulations and restrictions
and foreign exchange rate volatility.  Accordingly,  our future results could be
materially adversely affected by changes in these or other factors.

                                       43


Our sales and  corresponding  receivables  are made  primarily in United  States
dollars.  Through our  operations in Canada and elsewhere  outside of the United
States,   we  incur  research  and  development,   customer  support  costs  and
administrative expenses in Canadian and other local currencies.  We are exposed,
in  the  normal  course  of  business,   to  foreign  currency  risks  on  these
expenditures.  In our effort to manage  such  risks,  we have  adopted a foreign
currency  risk  management  policy  intended to reduce the effects of  potential
short-term  fluctuations on the results of operations stemming from our exposure
to these  risks.  As part of this risk  management,  we  typically  forecast our
operational  currency  needs,  purchase  such currency on the open market at the
beginning  of an  operational  period,  and hold these funds as a hedge  against
currency  fluctuations.  We usually limit the operational  period to 3 months or
less.  Because we do not engage in foreign  currency  exchange rate  fluctuation
risk management  techniques beyond these periods,  our cost structure is subject
to long-term changes in foreign exchange rates.

While we expect to continue  to use this  method to manage our foreign  currency
risk,  in the future we may decide to use foreign  exchange  contracts to manage
this risk.

We  regularly  analyze the  sensitivity  of our foreign  exchange  positions  to
measure our foreign  exchange risk. At December 31, 2002, a 10% shift in foreign
exchange rates would not have  materially  impacted our foreign  exchange income
because our foreign currency net asset position was immaterial.

         Debt

We issued $275,000,000 of convertible subordinated notes in August 2001. Because
we pay fixed interest coupons on our notes, market interest rate fluctuations do
not  impact  our  debt  interest  payments.  However,  the  fair  value  of  our
convertible  subordinated  notes  will  fluctuate  as a result of changes in the
price of our common stock,  changes in market  interest rates and changes in our
credit worthiness.

Our convertible  subordinated notes are not listed on any securities exchange or
included  in any  automated  quotation  system,  but have been  traded  over the
counter,  on the Portal Market or under Rule 144 of the  Securities Act of 1933.
The exchange prices from these trades are not always available to us and may not
be  reliable.  Trades  under the Portal  Market do not reflect all trades of the
securities and the figures recorded are not independently  verified. The average
bid and ask price of our convertible  subordinated notes on the Portal Market on
December  27, 2002 was $75.50 per $100 in face value,  resulting in an aggregate
fair value of  approximately  $207.6  million.  There were no reported trades on
December 28 or December 29, 2002.

Independent Auditors' Report

The Board of Directors of PMC-Sierra, Inc.

We have audited the accompanying consolidated balance sheets of PMC-Sierra, Inc.
and  subsidiaries  ("the  Company")  as of  December  31,  2002 and 2001 and the
related  consolidated  statements of operations,  stockholders'  equity and cash
flows for each of the three years in the period ended  December  31,  2002.  Our
audits also included the  financial  statement  schedule  listed in the Index at
Item 15(a).  These  consolidated  financial  statements and financial  statement
schedule are the responsibility of the Company's management.  Our responsibility
is to express an opinion on these financial  statements and financial  statement
schedule based on our audits.

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

In our opinion,  such consolidated  financial  statements present fairly, in all
material respects, the consolidated  financial position of PMC-Sierra,  Inc. and
subsidiaries  at December  31, 2002 and 2001,  and the  consolidated  results of
their  operations and their cash flows for each of the three years in the period
ended  December 31, 2002, in conformity  with  accounting  principles  generally
accepted in the United States of America.  Also, in our opinion,  such financial
statement  schedule,  when  considered  in  relation  to the basic  consolidated
financial statements taken as a whole,  presents fairly in all material respects
the information set forth therein.

As  discussed  in Note 1 to the  consolidated  financial  statements,  effective
January 1, 2002,  the Company  changed its method of accounting  for goodwill in
accordance with Statement of Financial  Accounting  Standards No. 142, "Goodwill
and Other Intangible Assets".

NOTE 1. Summary of Significant Accounting Policies

Description  of business.  PMC-Sierra,  Inc (the  "Company"  or "PMC")  designs,
develops,  markets and supports high-speed broadband  communications and storage
semiconductors  and  MIPS-based  processors  for service  provider,  enterprise,
storage,  and  wireless  networking  equipment.  The  Company  offers  worldwide
technical  and sales  support  through a network of  offices  in North  America,
Europe and Asia.

Basis  of  presentation.  The  accompanying  Consolidated  Financial  Statements
include the accounts of PMC-Sierra, Inc. and its wholly owned subsidiaries.  All
significant  inter-company  accounts and transactions have been eliminated.  The
Company's  fiscal year ends on the last Sunday of the calendar year. For ease of
presentation,  the reference to December 31 has been utilized as the fiscal year
end for all  financial  statement  captions.  Fiscal  years  2002 and 2001  each
consisted of 52 weeks.  Fiscal year 2000  consisted of 53 weeks.  The  Company's
reporting currency is the United States dollar.

Estimates.  The preparation of financial  statements and related  disclosures in
conformity with accounting principles generally accepted in the United States of
America  requires  management to make estimates and assumptions  that affect the
amounts reported in the financial  statements and accompanying notes.  Estimates
are used  for,  but not  limited  to,  the  accounting  for  doubtful  accounts,
inventory  reserves,  depreciation and amortization,  asset  impairments,  sales
returns,  warranty costs,  income taxes,  restructuring  costs and other special
charges, and contingencies. Actual results could differ from these estimates.

Cash  equivalents,  short-term  investments  and investments in bonds and notes.
Cash  equivalents are defined as highly liquid debt  instruments with maturities
at the date of purchase of 90 days or less.  Short-term  investments are defined
as money market instruments or bonds and notes with original  maturities greater
than 90 days, but less than one year. Investments in bonds and notes are defined
as bonds and notes with original or remaining  maturities greater than 365 days.
Any investments in bonds and notes maturing within one year of the balance sheet
date are reclassified to and reported as short-term investments.

Under  Statement of Financial  Accounting  Standards  No. 115,  "Accounting  for
Certain  Investments  in Debt  and  Equity  Securities",  management  classifies
investments as  available-for-sale  or  held-to-maturity at the time of purchase
and  re-evaluates  such  designation as of each balance sheet date.  Investments
classified  as  held-to-maturity  securities  are stated at amortized  cost with
corresponding  premiums or discounts  amortized against interest income over the
life of the investment.  Marketable equity and debt securities not classified as
held-to-maturity  are  classified  as  available-for-sale  and  reported at fair
value.  The cost of  securities  sold is based  on the  specific  identification
method. Unrealized gains and losses on these investments, net of any related tax
effect are included in equity as a separate component of stockholders' equity.

Restricted  cash.  Restricted  cash  consists  of  cash  pledged  with a bank as
collateral for letters of credit issued as security for leased facilities.

Inventories.  Inventories are stated at the lower of cost (first-in,  first out)
or market  (estimated  net  realizable  value).  Cost is computed using standard
cost, which  approximates  actual average cost. The Company  provides  inventory
allowances on obsolete  inventories  and  inventories in excess of  twelve-month
demand for each specific part.

                                       51


The components of net inventories are as follows:

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


Investments  in  non-public  entities.  The Company has certain  investments  in
non-publicly  traded  companies  and venture  capital funds in which it has less
than 20% of the  voting  rights  and in which it does not  exercise  significant
influence.  The Company  monitors  these  investments  for  impairment and makes
appropriate reductions in carrying values when necessary.  These investments are
included in Other  investments and assets on the Company's balance sheet and are
carried at cost, net of write-downs for impairment.

Investments in public companies. The Company has certain investments in publicly
traded companies in which it has less than 20% of the voting rights and in which
it does not exercise  significant  influence.  Certain of these  investments are
subject to resale restrictions. Securities restricted for more than one year are
carried at cost.  Securities  restricted for less than one year from the balance
sheet date and securities not subject to resale  restrictions  are classified as
available-for-sale  and reported at fair value, based upon quoted market prices,
with the unrealized gains or losses, net of any related tax effect,  included in
equity as a separate  component of stockholders'  equity.  The Company evaluates
its  investments  in public  companies  for  factors  indicating  an other  than
temporary  impairment and makes  appropriate  reductions in carrying value where
necessary.

Investments in equity  accounted  investees.  Investees in which the Company has
between 20% and 50% of the voting  rights,  and in which the  Company  exercises
significant  influence,  are accounted for using the equity method.  The Company
sold a portion of its only  investment in an equity  accounted  investee  during
2000 and since that  disposition  has held less than 20% of the voting rights of
this investee.

Deposits for wafer fabrication capacity. The Company has wafer supply agreements
with two independent foundries. Under these agreements, the Company has deposits
of $22.0  million (2001 - $22.0  million) to secure access to wafer  fabrication
capacity.  During 2002, the Company  purchased  $32.3 million ($42.7 million and
$81.1 million in 2001 and 2000, respectively) from these foundries. Purchases in
any year may or may not be  indicative  of any future  period  since  wafers are
purchased based on current market pricing and the Company's volume  requirements
change in relation to sales of its products.

In each year,  the  Company is  entitled to receive a refund of a portion of the
deposits  based on the annual  purchases  from these  suppliers  compared to the
target levels in the wafer supply  agreements.  Based on 2002  purchases and the
current agreements, the Company is not entitled to a refund from these suppliers
in 2003. If the Company does not receive back the balance of its deposits during
the term of the agreements,  then the  outstanding  deposits will be refunded to
the Company after the termination of the agreements at the end of 2003.

Property and equipment,  net.  Property and equipment are stated at cost, net of
write-downs for impairment,  and depreciated using the straight-line method over
the estimated useful lives of the assets, ranging from two to five years, or the
applicable lease term, whichever is shorter.

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



In 2002, the Company recorded an impairment charge of $1.8 million for machinery
and equipment that was removed from service.

Goodwill and other intangible assets.  Goodwill,  developed technology and other
intangible assets are carried at cost less accumulated  amortization,  which had
been computed on a  straight-line  basis over the economic  lives,  ranging from
three to seven years, of the respective assets.

In July 2001, the Financial  Accounting  Standards Board (FASB) issued Statement
of Financial Accounting Standard No. 141 (SFAS 141), "Business Combinations" and
Statement of Financial  Accounting  Standard No. 142 (SFAS 142),  "Goodwill  and
Other Intangible Assets".

SFAS 141 requires that business combinations be accounted for under the purchase
method of accounting and addresses the initial  recognition  and  measurement of
assets acquired,  including goodwill and intangibles, and liabilities assumed in
a business  combination.  The Company  adopted SFAS 141 on a  prospective  basis
effective July 1, 2001. The adoption of SFAS 141 did not have a material  effect
on the Company's financial statements,  but will impact the accounting treatment
of future acquisitions.

SFAS 142  requires  goodwill  to be  allocated  to, and  assessed  as part of, a
reporting  unit.  In  accordance  with  SFAS  142,  goodwill  will no  longer be
amortized but instead will be subject to impairment tests at least annually.  In
conjunction  with the  implementation  of SFAS 142,  the Company  completed  the
transitional  impairment  test as of the beginning of 2002 and determined that a
transitional impairment charge would not be required. The Company also completed
its annual  impairment  test in December 2002 and  determined  that there was no
impairment of goodwill.

The Company  adopted SFAS 142 on a prospective  basis at the beginning of fiscal
2002 and stopped amortizing goodwill totaling $7.1 million,  thereby eliminating
goodwill  amortization of  approximately  $2.0 million in 2002. Net loss and net
loss per share adjusted to exclude goodwill and workforce amortization for 2002,
2001 and 2000 are as follows:

In 2001,  the  Company  recorded  a total  impairment  charge of $269.8  million
related to goodwill  (see Note 3) and $925,000  related to developed  technology
and other intangible assets.

Impairment of long-lived  assets.  The Company  reviews its  long-lived  assets,
other than goodwill,  for impairment whenever events or changes in circumstances
indicate  that the  carrying  value of such  assets may not be  recoverable.  To
determine recoverability,  the Company compares the carrying value of the assets
to the estimated future  undiscounted  cash flows.  Measurement of an impairment
loss for long-lived assets held for use is based on the fair value of the asset.
Long-lived  assets  classified  as held for sale are  reported  at the  lower of
carrying  value and fair value less estimated  selling  costs.  For assets to be
disposed  of other  than by sale,  an  impairment  loss is  recognized  when the
carrying value is not recoverable and exceeds the fair value of the asset.

For  goodwill,  an  impairment  loss will be  recorded  to the  extent  that the
carrying amount of the goodwill exceeds its implied fair value.


Accrued liabilities. The components of accrued liabilities are as follows:

Foreign currency translation. For all foreign operations, the U.S. dollar is the
functional currency. Assets and liabilities in foreign currencies are translated
into U.S.  dollars using the exchange  rate at the balance sheet date.  Revenues
and expenses are translated at average rates of exchange during the year.  Gains
and losses from foreign currency transactions are included in Interest and other
income, net.

Fair value of  financial  instruments.  The  estimated  fair value of  financial
instruments  has  been   determined  by  the  Company  using  available   market
information  and  appropriate  valuation  methodologies.  However,  considerable
judgment is required in  interpreting  market data to develop the  estimates  of
fair value.  Accordingly,  the estimates  presented  herein are not  necessarily
indicative  of the amounts that the Company  could  realize in a current  market
exchange.

The Company's carrying value of cash equivalents,  accounts receivable, accounts
payable and other accrued  liabilities  approximates fair value because of their
short maturities.

The fair value of the Company's short-term investments,  and investment in bonds
and notes are  determined  using  estimated  market  prices  provided  for those
securities  (see Note 4). The fair value of investments  in public  companies is
determined  using quoted market prices for those  securities.  The fair value of
investments in non-public  entities and the fair value of the deposits for wafer
fabrication capacity are not readily determinable.

The fair value of the Company's  obligations  under capital leases and long-term
debt other than the convertible  subordinated  notes approximated their carrying
value.

The fair value of the  convertible  subordinated  notes at December 31, 2002 was
approximately  $207.6  million,  based on the average bid and ask price of these
notes.  The fair  value of these  notes at  December  31,  2001 was not  readily
determinable as there was no established  public training market for them. These
notes are not listed on any  securities  exchange or  included in any  automated
quotation  system.  The  recorded  bid and ask price may not be  reliable as the
figures cannot be independently verified and not all trades are reflected.

On  January  1, 2001 PMC  adopted  Financial  Accounting  Standards  Board  FASB
Statement of Financial  Accounting Standards No. 133, "Accounting for Derivative
Instruments  and Hedging  Activities"  (SFAS 133).  SFAS 133  requires  that all
derivatives  be recorded on the  balance  sheet at fair value.  SFAS 133 did not
have a  material  impact  on the  date  of  adoption  and did  not  result  in a
cumulative  transition  adjustment.  As of and for the year ended  December  31,
2002,  the use of  derivative  financial  instruments  was not  material  to our
results of operations or our financial position.

Concentrations.  The Company  maintains its cash, cash  equivalents,  short-term
investments and long-term  investments in investment grade financial instruments
with  high-quality   financial   institutions,   thereby  reducing  credit  risk
concentrations.

At December  31,  2002,  approximately  22% (2001 - 20%) of accounts  receivable
represented  amounts  due from one of the  Company's  distributors.  The Company
believes that this  concentration and the concentration of credit risk resulting
from  trade  receivables  owing  from  high-technology   industry  customers  is
substantially  mitigated by the Company's credit evaluation process,  relatively
short collection  terms and the geographical  dispersion of the Company's sales.
The Company  generally  does not require  collateral  security  for  outstanding
amounts.

The  Company  relies on a  limited  number of  suppliers  for wafer  fabrication
capacity.

Revenue  recognition.  Revenues from product sales direct to customers and minor
distributors  are  recognized at the time of shipment.  The Company  accrues for
warranty costs, sales returns and other allowances at the time of shipment based
on its  experience.  Certain of the  Company's  product  sales are made to major
distributors  under  agreements  allowing for price  protection  and/or right of
return on products  unsold.  Accordingly,  the  Company  defers  recognition  of
revenue on such sales until a distributor sell the products.

Product warranties.  The Company provides a one-year limited warranty on most of
its  standard  products and accrues for the cost of this  warranty  based on its
experience  at the time of  shipment.  Reconciliation  of the  product  warranty
liability for the year ended December 31, 2002 is as follows:

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

The  semiconductor  industry is subject to volatility in shipment levels and the
rate of warranty returns tends to fluctuate depending on whether the industry is
in times of growth or  contraction.  The Company  adjusts its rate of accrual to
reflect the level of returns typical of the industry cycle.

Stock-based  compensation.  The Company accounts for stock-based compensation in
accordance with the intrinsic value method prescribed by APB Opinion No. 25 (APB
25),  "Accounting for Stock Issued to Employees".  Under APB 25, compensation is
measured as the amount by which the market price of the underlying stock exceeds
the  exercise  price of the option on the date of grant;  this  compensation  is
amortized over the vesting period.

Pro forma  information  regarding  net income  (loss) and net income  (loss) per
share is required by SFAS 123 for awards  granted or modified after December 31,
1994 as if the Company had  accounted  for its  stock-based  awards to employees
under  the fair  value  method  of SFAS  123.  The fair  value of the  Company's
stock-based  awards to employees  was  estimated  using a  Black-Scholes  option
pricing model. The  Black-Scholes  model was developed for use in estimating the
fair value of traded  options  that have no vesting  restrictions  and are fully
transferable.  In addition, the Black-Scholes model requires the input of highly
subjective  assumptions  including the expected stock price volatility.  Because
the Company's stock-based awards to employees 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 stock-based awards to employees. The fair value
of the  Company's  stock-based  awards  to  employees  was  estimated  using the
multiple option  approach,  recognizing  forfeitures as they occur,  assuming no
expected dividends and using the following weighted average assumptions:

The  weighted-average  estimated fair values of employee  stock options  granted
during  fiscal  2002,  2001,  and 2000 were $4.07,  $10.98 and $74.32 per share,
respectively.

If the computed fair values of 2002, 2001, and 2000 awards had been amortized to
expense  over the vesting  period of the awards as  prescribed  by SFAS 123, net
income (loss) and net income (loss) per share would have been:

Income taxes. Income taxes are reported under Statement of Financial  Accounting
Standards No. 109 and,  accordingly,  deferred income taxes are recognized using
the asset and liability method,  whereby deferred tax assets and liabilities are
recognized for the future tax consequences  attributable to differences  between
the financial  statement carrying amounts of existing assets and liabilities and
their  respective tax bases,  and operating loss and tax credit carry  forwards.
Valuation allowances are provided if, after considering  available evidence,  it
is more likely than not that some or all of the  deferred tax assets will not be
realized.

Net  income  (loss)  per  common  share.  Basic net  income  (loss) per share is
computed using the weighted average number of common shares  outstanding  during
the  period.  The  PMC-Sierra  Ltd.  Special  Shares  have been  included in the
calculation of basic net income (loss) per share.  Diluted net income (loss) per
share is  computed  using the  weighted  average  number of common and  dilutive
common  equivalent  shares  outstanding  during  the  period.   Dilutive  common
equivalent shares consist of stock options and warrants.

Share and per common share data presented reflect the two-for-one stock split in
the form of a 100% stock dividend effective February 2000.

Segment  reporting.   Segmented  information  is  reported  under  Statement  of
Financial Accounting  Standards No. 131 (SFAS 131),  "Disclosures about Segments
of an Enterprise and Related  Information".  SFAS 131 uses a management approach
to report  financial and  descriptive  information  about a company's  operating
segments.  Operating segments are revenue-producing  components of a company for
which separate  financial  information is produced  internally for the company's
management.  Under  this  definition,  the  Company  operated,  for all  periods
presented, in two segments: networking and non-networking products.

Recently issued  accounting  standards.  In June 2002, the Financial  Accounting
Standards Board (FASB) issued Statement of Financial Accounting Standard No. 146
(SFAS 146),  "Accounting for Costs Associated with Exit or Disposal Activities".
SFAS 146  requires  that the  liability  for a cost  associated  with an exit or
disposal  activity  be  recognized  at its  fair  value  when the  liability  is
incurred.  Under  previous  guidance,  a liability  for  certain  exit costs was
recognized at the date that management committed to an exit plan. As SFAS 146 is
effective  only for exit or disposal  activities  initiated  after  December 31,
2002,  the adoption of this  statement  will not impact the Company's  financial
statements  for 2002,  but will  affect the  accounting  for any  restructurings
initiated  after  2002.  In  January  2003,  the  Company  announced  a  further
restructuring  plan, the costs of which will be accounted for in accordance with
SFAS 146.

In  November  2002,  the  FASB  issued  FASB  Interpretation  No.  45 (FIN  45),
"Guarantor's  Accounting and Disclosure  Requirements for Guarantees,  Including
Indirect  Guarantees  of  Indebtedness  of Others".  FIN 45  requires  that upon
issuance of a guarantee,  a guarantor  must  recognize a liability  for the fair
value  of an  obligation  assumed  under  a  guarantee.  FIN  45  also  requires
additional  disclosures  by a  guarantor  in its  interim  and annual  financial
statements  about  the  obligations   associated  with  guarantees  issued.  The
recognition  provisions of FIN 45 will be effective for any guarantees  that are
issued or  modified  after  December  31,  2002.  The  Company  has  adopted the
disclosure   requirements  and  is  currently  evaluating  the  effects  of  the
recognition  provisions of FIN 45; however, it does not expect that the adoption
will have a material impact on the Company's  results of operations or financial
position.

In December 2002, the FASB issued Statement of Financial Accounting Standard No.
148 (SFAS 148),  "Accounting  for  Stock-Based  Compensation  -  Transition  and
Disclosure". SFAS 148 provides alternative methods of transition for a voluntary
change to the fair value based method of  accounting  for  stock-based  employee
compensation.  SFAS 148 also  requires  prominent  disclosure in the "Summary of
Significant Accounting Policies" of both annual and interim financial statements
about the method of accounting for  stock-based  employee  compensation  and the
effect of the method used on reported results.  The Company has adopted SFAS 148
for the 2002  fiscal year end.  Adoption  of this  statement  has  affected  the
location  of  the  Company's   disclosure  within  the  Consolidated   Financial
Statements,  but will not impact the Company's results of operation or financial
position  unless the Company  changes to the fair value method of accounting for
stock-based employee compensation.

Purchase Combinations:

Fiscal 2000

Octera Corporation.

On December 12, 2000, the Company completed the purchase of Octera  Corporation,
a privately held company located in San Diego,  CA, that provided digital design
services for Application  Specific  Integrated  Circuits  ("ASICs"),  boards and
systems with its primary focus on ASIC design.  The Company paid cash and issued
common stock with an aggregate fair value of approximately $16 million to effect
this transaction.

Datum Telegraphic, Inc.

On July 21,  2000,  the Company  completed  the  purchase of the 92% interest of
Datum Telegraphic, Inc. that it did not already own in exchange for the issuance
of approximately  681,000  exchangeable  shares (see Note 10) and options with a
fair  value of $107.4  million,  cash of $17  million  and  acquisition  related
expenditures  of $875,000.  Datum, a wireless  semiconductor  company located in
Vancouver,  Canada,  made digital signal  processors  that allow traffic for all

Malleable Technologies, Inc.

On June 27, 2000, the Company exercised an option to acquire the 85% interest of
Malleable  Technologies,  Inc.  that it did not already own in exchange  for the
issuance  of  approximately  1,250,000  common  shares and  443,000  options and
warrants with a fair value totaling $293 million and  acquisition  related costs
of $825,000. Malleable, a fabless semiconductor company located in San Jose, CA,
made digital signal  processors for  voice-over-packet  processing  applications
which bridge voice and  high-speed  data networks by  compressing  voice traffic
into ATM or IP packets.

                                       61


The  acquisitions  of Octera,  Datum and Malleable  were accounted for using the
purchase  method of  accounting  and  accordingly,  the  Consolidated  Financial
Statements include the operating results of each acquisition from the respective
acquisition dates.

The fair value of the common shares of the Company issued to acquire  Malleable,
Datum, and Octera was based on the closing market price of the Company's stock a
short period before and after the date the terms of the acquisitions were agreed
to by the parties and announced to the public.

The total consideration, including acquisition costs, was allocated based on the
estimated fair values of the net assets  acquired on the respective  acquisition
dates as follows:






(in thousands)                             Octera           Datum          Malleable          Total

A portion of the purchase  price of each  acquisition  was allocated to unearned
compensation  based on the value of certain  unvested  shares and options of the
Company issued to effect each  acquisition.  The fair value of the common shares
that  were  issued  to  acquire  Malleable  and that  were  subject  to  vesting
provisions based on continuing employment was recorded as unearned compensation.
The intrinsic  value of the unvested  shares and options issued to acquire Datum
and Octera,  which were acquired  after July 1, 2000,  was allocated to unearned
compensation. Unearned compensation will be recognized as compensation cost over
the respective remaining future service periods.

Purchased In Process Research and Development

The amounts  allocated to in process  research and  development  ("IPR&D")  were
determined through independent valuations using established valuation techniques
in the high-technology industry. The value allocated to IPR&D was based upon the
forecasted operating after-tax cash flows from the technology  acquired,  giving
effect to the stage of completion at the acquisition date. Estimated future cash
flows  related to the IPR&D were made for each  project  based on the  Company's
estimates  of  revenues,  operating  expenses and income taxes from the project.
These estimates were consistent  with  historical  pricing,  margins and expense
levels for similar products.

Revenues  were  estimated  based on  relevant  market  size and growth  factors,
expected industry trends, individual product sales cycles and the estimated life
of each product's underlying  technology.  Estimated operating expenses,  income
taxes  and  charges  for the  use of  contributory  assets  were  deducted  from
estimated revenues to determine estimated after-tax cash flows for each project.
These future cash flows were further  adjusted for the value  contributed by any
core  technology  and  development   efforts   expected  to  be  completed  post
acquisition.

                                       62


These forecasted cash flows were then discounted based on rates derived from the
Company's  weighted  average cost of capital,  weighted average return on assets
and venture capital rates of return adjusted upward to reflect  additional risks
inherent in the  development  life cycle.  The risk adjusted  discount rate used
involved  consideration of the characteristics and applications of each product,
the inherent uncertainties in achieving technological  feasibility,  anticipated
levels of market  acceptance  and  penetration,  market  growth  rates and risks
related to the impact of potential changes in future target markets.

Based on this analysis,  the acquired technology that had reached  technological
feasibility  was  capitalized.  Acquired  technology  that  had not yet  reached
technological  feasibility and for which no alternative  future uses existed was
expensed upon acquisition.

Malleable and Datum:

Malleable developed  programmable  integrated circuits that perform high-density
Voice  Over  Packet  applications.  The  in  process  technology  acquired  from
Malleable was designed to detect  incoming voice channels and process them using
voice  compression  algorithms.  The compressed  voice was converted,  using the
appropriate  protocols,  to ATM cells or IP packets to  achieve  higher  channel
density and to support  multiple  speech  compression  protocols  and  different
packetization  requirements.  At the date of acquisition  the Company  estimated
that  Malleable's  technology  was 58%  complete  and the costs to complete  the
project to be $4.4 million.

Datum  designed  power  amplifiers  for use in wireless  communications  network
equipment.  The  technology  acquired  from  Datum  was a  digitally  controlled
amplifier  architecture,  which was  designed to increase  base  station  system
capacities,  while reducing cost, size and power  consumption of radio networks.
At the date of acquisition,  the Company  estimated that Datum's  technology was
59% complete and the costs to complete the project to be $1.8 million.

These  estimates  were  determined by comparing the time and costs spent to date
and the complexity of the technologies achieved to date to the total costs, time
and  complexities  that PMC  expected  to expend to bring  the  technologies  to
completion.

The amounts allocated to IPR&D for Malleable and Datum of $31.5 million and $6.7
million, respectively, were expensed upon acquisition, as it was determined that
the  underlying  projects  had not  reached  technological  feasibility,  had no
alternative   future  uses  and  successful   development  was  uncertain.   The
risk-adjusted  discount rates used to determine the value of IPR&D for Malleable
was 35% and for Datum was 30%.

The Company  discontinued  development of the technology acquired from Malleable
in the second quarter of 2001. See Note 3 "Restructuring and other costs".

Development of the chip  incorporating  the  technology  acquired from Datum was
completed in the fourth quarter of 2000 and the costs incurred to that date were
in line with the Company's  initial  expectations.  Since then,  the Company has
completed  the  required   firmware  related  to  this  chip  and  has  extended
development of the Datum technology to a follow-on product. The general economic
slowdown has delayed the introduction of the third generation base stations into
which the Company had expected the Datum  technology to be  incorporated.  It is
currently  uncertain when the Datum products will begin to generate  significant
revenues.

                                       63



NOTE 3.   Restructuring and Other Costs

On January 16, 2003, the Company  announced that it was  undertaking a corporate
restructuring  to further reduce  operating  expenses.  The  restructuring  plan
includes the  termination  of  approximately  175  employees  and the closure of
design centers in Maryland,  Ireland and India.  PMC will record a restructuring
charge  for  workforce  reduction,   facility  lease  costs  and  related  asset
impairments  as these  liabilities  will be  incurred  in the first  and  second
quarters of 2003.

During 2002, the Company paid out $27.5 million in connection  with October 2001
restructuring activities.

Cash payments  made in 2002 for  restructuring  activities  related to the March
2001 restructuring plan were $2.7 million.

There were no  additional  restructurings  in 2002 nor were there any changes in
estimates  related  to  2001  restructurings  that  affected  the  Statement  of
Operations.

Restructuring - October 18, 2001

Due to a  continued  decline in market  conditions,  the Company  implemented  a
restructuring  plan in the fourth  quarter of 2001 to reduce the operating  cost
structure.  This  restructuring  plan included the termination of 341 employees,
the  consolidation  of additional  excess  facilities,  and the  curtailment  of
additional research and development projects. As a result, PMC recorded a second
restructuring charge of $175.3 million in the fourth quarter of 2001.

The  following  summarizes  the  activity  in  the  October  2001  restructuring
liability:

Restructuring - March 26, 2001

                                       64


In the first quarter of 2001, PMC implemented a  restructuring  plan in response
to the decline in demand for our networking products and consequently recorded a
restructuring  charge of $19.9  million.  The  restructuring  plan  included the
involuntary  termination  of 223 employees  across all business  functions,  the
consolidation  of a number of facilities and the curtailment of certain research
and development projects.

The following summarizes the activity in the March 2001 restructuring liability:

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



The Company  completed the  restructuring  activities  contemplated in the March
2001 plan by June 30, 2002.

During the first six months of fiscal 2002,  the Company  made cash  payments of
$2.8 million in connection with this restructuring.  The remaining restructuring
liability of $1.4 million at June 30, 2002 related  primarily to facility  lease
payments,  net of estimated  sublease  revenues,  and was  classified as accrued
liabilities on the balance sheet. The Company does not expect this restructuring
to have any impact on its Statement of Operations in the future.


Impairment of Goodwill and Intangible Assets

During the second quarter of 2001,  PMC made a decision to  discontinue  further
development of the technology acquired in the purchase of Malleable. The Company
did not expect to have any future cash flows  related to these assets and had no
alternative  use  for the  technology.  Accordingly,  the  Company  recorded  an
impairment  charge of $189  million,  equal to the  remaining  net book value of
goodwill and intangible assets related to Malleable.

In the fourth quarter of 2001, due to a continued  decline in market  conditions
and a delay in  introduction  of certain  products  to the  market,  the Company
completed an assessment  of the future  revenue  potential  and estimated  costs
associated  with all  acquired  technologies.  As a result of this  review,  the
Company  recorded a further  impairment  charge of $80.8 million  related to the
acquired goodwill and other intangibles  recognized in the purchase of Datum and
Octera.  The Company recorded a charge of $79.3 million,  measured as the amount
by which the carrying value of the goodwill and intangibles exceeded the present
value of  estimated  future cash flows  related to these  assets,  to impair the
goodwill and intangibles  acquired in the purchase of Datum.  The remaining $1.5
million  impairment  of  goodwill  resulted  from the  cancellation  of Octera's
research and development activities during 2001.

Write-down of Inventory

The Company  recorded a write-down  of excess  inventory of $4.0 million in 2002
and $20.7  million in 2001.  The continued  industry  wide  reduction in capital
spending and resulting  decrease in demand for the Company's  products  prompted
the Company to assess its current  inventory  levels compared to sales forecasts
for the next twelve months.  The excess inventory charge,  which was included in
cost of revenues,  was calculated in accordance with the Company's policy, which
is based on inventory levels in excess of estimated 12-month demand.

The total fair value of  held-to-maturity  investments  at December 31, 2002 was
$397.8 million (2001 - $358.1 million), with remaining maturities ranging from 1
month to 28 months.

The total fair value of available-for-sale  investments at December 31, 2002 was
$94.5 million (2001 - $86.3 million) with remaining  maturities  ranging from 22
to 25 months.

In 2002 the Company sold  investments in bonds and notes with a total  amortized
cost of $10.1 million that were classified as  held-to-maturity.  The securities
were  downgraded  in credit  quality and as a result no longer met the Company's
internal  investment  policy.  The  realized  gain or loss on  these  sales  was
immaterial.

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



At December  31, 2002,  the Company held 2.0 million  shares (2001 - 2.3 million
shares) of Sierra Wireless,  Inc., of which 1.2 million were previously  subject
to resale  restrictions  and could not be sold until May 2002.  The  Company has
classified  these  shares  as  available-for-sale  and has  recorded  a  related
unrealized  holding  gain at  December  31, 2002 of $6.3  million  (2001 - $41.6
million).

The Company also has  investments  in non-public  entities,  either  directly or
through  venture  funds,  which  include   investments  in  early-stage  private
technology  companies  of  strategic  interest to the  Company.  The Company has
commitments  to invest  additional  capital into venture  funds (see Note 8). In
2002, the Company made additional cash investments of $10.1 million (2001 - $5.7
million; 2000 - $24.8 million) in non-public entity investments.

During  the  year  ended  December  31,  2002,  the  Company  sold  some  of its
investments in public and non-public companies for cash proceeds of $5.8 million
(2001 - $3.3 million; 2000 - $59.7 million) and recorded gross realized gains of
$3.7 million (2001 - $2.9 million; 2000 - $58.5 million). There were no non-cash
proceeds from sales of investments in 2002 (2001 - $1.7 million; 2000 - nil). Of
these amounts,  cash proceeds of $5.3 million (2001 - $2.1 million; 2000 - $59.7
million) and gross realized  gains of $3.3 million (2001 - $1.9 million;  2000 -
$58.5 million) related to the disposition of investments classified as available
for sale.

The Company  monitors the value of its investments for impairment and records an
impairment  charge to reflect any decline in value below its cost basis, if that
decline is considered to be other than  temporary.  The assessment of impairment
in  carrying  value  is based on the  market  value  trends  of  similar  public
companies,  the current  business  performance  of the entities in which we have
invested,  and if  available,  the  estimated  future  market  potential  of the
companies and venture funds. In 2002, the Company recorded an impairment  charge
of $15.3 million (2001 - $17.5 million) related to its investments in non-public
entities.  This  charge  is  included  in "Gain  (loss) on  investments"  on the
Consolidated Statement of Operations.


NOTE 6.  Lines of credit

At December 31, 2002,  the Company had available a revolving line of credit with
a bank under which the Company may borrow up to $5.3  million  with  interest at
the bank's  alternate  base rate  (annual rate of 4.75% at December 31, 2002) as
long as the Company  maintains  eligible  investments with the bank in an amount
equal to its drawings.  This agreement expires in December 2004. At December 31,
2002,  $5.3  million  cash was  deposited  with the bank to  offset  the  amount
committed under letters of credit.

                                       67


The existing line of credit  replaces the $25 million  revolving  line of credit
that was available to the Company at the end of 2001. At December 31, 2001, $5.3
million of the available $25 million line of credit was committed  under letters
of credit.


NOTE 7.   Convertible subordinated notes

In August  2001,  the Company  issued $275 million of  convertible  subordinated
notes  maturing on August 15,  2006.  In  connection  with the issuance of these
convertible  subordinated notes, the Company incurred approximately $7.8 million
of issuance costs,  which consisted  primarily of investment  banker fees, legal
and other  professional  fees,  which have been deferred and are being amortized
over the term of the notes.  The five-year term notes bear interest at a rate of
3.75% per annum and are convertible into an aggregate of approximately 6,480,650
shares of PMC's  common  stock at any time prior to  maturity,  at a  conversion
price of approximately $42.43 per share.

The Company may redeem the notes,  in whole or in part, at any time after August
19, 2004 at a redemption  price  ranging from 100.75% to 101.5% of the principal
amount of notes  outstanding  depending on the  redemption  date.  Under certain
conditions  prior to August 19, 2004,  the Company may redeem any portion of the
notes at a price of 100% of the principal  amount of notes,  plus a "make whole"
amount for accrued and unpaid interest to the redemption date. The fair value of
this make whole  provision was  determined to be immaterial at the time the debt
was issued and at December 31, 2002.

These notes are subject to  restrictive  covenants  including  those  concerning
payments  on the  notes  and  other  indebtedness.  In the  event of a change in
control of the Company,  the  noteholders  may require the Company to repurchase
their notes.


NOTE 8. Commitments and Contingencies

Operating  leases.  The Company  leases its  facilities  under  operating  lease
agreements, which expire at various dates through December 31, 2011.

Rent expense  including  operating  costs for the years ended December 31, 2002,
2001 and 2000 was $12.4 million,  $15.9 million and $8.3 million,  respectively.
Excluded from rent expense for 2002 was additional  rent and operating  costs of
$27.5  million (2001 - $3.4 million)  related to excess  facilities,  which were
accrued as part of the restructuring charges in 2001.

In  connection  with the  restructuring  charges  recorded in 2001,  the Company
recorded a charge of $128.3  million for exiting and  terminating  certain lease
facilities that are included in the table below.

Minimum future rental payments under operating leases are as follows:

                                       68


Supply agreements.  The Company has wafer supply agreements with two independent
foundries,  which expire in December 2003. Under these agreements, the suppliers
are obligated to provide certain  quantities of wafers per year.  Neither of the
agreements  have minimum unit volume  purchase  requirements  but the Company is
obligated  under one of the  agreements to purchase in future  periods a minimum
percentage of its total annual wafer requirements,  provided that the foundry is
able to continue to offer competitive technology, pricing, quality and delivery.

Investment  agreements.  The Company participates in four professionally managed
venture funds that invest in  early-stage  private  technology  companies  which
participate in markets of strategic  interest to the Company.  From time to time
these funds request additional capital for private  placements.  The Company has
committed to invest an  additional  $38.1  million in these funds,  which may be
requested by the fund managers at any time over the next seven years.

Contingencies.  In the normal course of business, the Company receives and makes
inquiries with regard to possible patent infringements.  Where deemed advisable,
the Company may seek or extend  licenses or negotiate  settlements.  Outcomes of
such  negotiations  may not be  determinable  at any  point  in  time;  however,
management does not believe that such licenses or settlements will, individually
or in the aggregate,  have a material adverse effect on the Company's  financial
position, results of operations or cash flows.


NOTE 9.  Special Shares

At December 31, 2002 and 2001, the Company maintained a reserve of 3,196,000 and
3,373,000 shares,  respectively,  of PMC common stock to be issued to holders of
PMC-Sierra, Ltd. (LTD) special shares.

The special  shares of LTD, the Company's  principal  Canadian  subsidiary,  are
redeemable or exchangeable  for PMC common stock.  Special shares do not vote on
matters  presented  to the  Company's  stockholders,  but in all other  respects
represent the economic and  functional  equivalent of PMC common stock for which
they can be  redeemed or  exchanged  at the option of the  holders.  The special
shares have class  voting  rights with respect to  transactions  that affect the
rights of the special shares as a class and for certain extraordinary  corporate
transactions  involving  LTD.  If LTD files for  bankruptcy,  is  liquidated  or
dissolved,  the special  shares  receive as a preference the number of shares of
PMC common stock  issuable on  conversion  plus a nominal  amount per share plus
unpaid  dividends,  or at the holder's option convert into LTD ordinary  shares,
which are the functional equivalent of voting common stock. If the Company files
for bankruptcy, is liquidated,  or dissolved,  special shares of LTD receive the
cash  equivalent of the value of PMC common stock into which the special  shares
could be converted,  plus unpaid  dividends,  or at the holder's  option convert
into LTD ordinary shares. If the Company materially  breaches its obligations to
special  shareholders  of LTD (primarily to permit  conversion of special shares
into PMC common stock),  the special  shareholders may convert their shares into
LTD ordinary shares.

These special shares of LTD are classified outside of stockholders' equity until
such shares are exchanged for PMC common stock.  Upon exchange,  amounts will be
transferred  from the LTD special shares  account to the Company's  common stock
and additional paid-in capital on the consolidated balance sheet.

NOTE 10. Stockholders' Equity

Authorized  capital stock of PMC. At December 31, 2002 and 2001, the Company had
an authorized capital of 905,000,000 shares, 900,000,000 of which are designated
"Common  Stock",  $0.001  par  value,  and  5,000,000  of which  are  designated
"Preferred Stock", $0.001 par value.

Stock Splits.  In January  2000,  the  Company's  Board of Directors  approved a
two-for-one  split of the Company's common stock in the form of a stock dividend
that was applicable to shareholders of record on January 31, 2000, and effective
on February 14, 2000. All references to share and per share data for all periods
presented have been adjusted to give effect to this stock dividend.

Warrants.  During 1996, the Company issued a warrant to purchase  100,000 shares
of common stock at $2.31 per share to an  investment  banking firm in settlement
for services  previously  expensed.  This warrant was fully  exercised in August
2000.

In 1999,  as a result of the  Company's  acquisition  of  Abrizio,  the  Company
assumed  warrants to purchase 174,580 shares of common stock at $1.66 per share.
In 2000, as a result of the Company's acquisitions of AANetcom, Extreme, QED and
SwitchOn,  the Company assumed warrants to purchase 50,759,  63,162,  68,434 and
780  shares of common  stock at  $9.36,  $3.06,  $5.26  and  $89.76  per  share,
respectively.  In 2001, 50,759 of these warrants were cancelled. At December 31,
2002,  2001,  and 2000,  there were 30,100  warrants  outstanding  at a weighted
average  exercise  price of $1.66 per share,  42,138  warrants  outstanding at a
weighted  average  exercise  price of  $1.66  per  share,  and  92,897  warrants
outstanding  at  a  weighted   average   exercise  price  of  $5.87  per  share,
respectively.  All  warrants  outstanding  at December  31, 2002 expire in March
2003.

Convertible  Preferred  Stock of QED.  QED,  which was acquired by PMC in August
2000 in a transaction  accounted for under the pooling  method (see Note 2), had
preferred  stock  comprised  of $0.001  par  value  per share  Series A, B, C, D
convertible  preferred shares.  Simultaneously with the closing of QED's initial
public offering on February 1, 2000, all issued and outstanding  shares of QED's
convertible  preferred  stock,  with a  carrying  value of $39.9  million,  were
automatically  converted into 13,619,000  shares of QED common stock. All shares
of common  stock of QED were  exchanged  for  shares of PMC  common  stock at an
exchange ratio of 0.385 (see Note 2) per QED common share.

Exchangeable  Shares.  As a result of the  acquisitions  of Extreme and Datum in
2000,  each  holder  of the  Extreme  and Datum  common  stock  received  shares
exchangeable into PMC common stock. The shares are  exchangeable,  at the option
of the holder, for PMC common stock on a share-for-share basis. The exchangeable
shares remain  securities of the Company and entitle the holders to dividend and
other rights economically  equivalent to that of PMC common stock and, through a
voting trust,  to vote at shareholder  meetings of the Company.  At December 31,
2002, 2001, and 2000, these shares were exchangeable  into 636,000,  712,000 and
1,386,000 PMC shares, respectively.

Stockholders' Rights Plan. On April 26, 2001, PMC adopted a stockholders' rights
plan. Under the rights plan, the Company issued a dividend of one right for each
share of common  stock of the Company held by  stockholders  of record as of May
25,  2001.  Each  right  will  initially  entitle  stockholders  to  purchase  a
fractional share of the Company's preferred stock for $325. However,  the rights
are not  immediately  exercisable  and will  become  exercisable  only  upon the
occurrence of certain events.  Upon occurrence of these events,  unless redeemed
for $0.001 per right, the rights will become exercisable by holders,  other than
rights held by a potential  unsolicited third party acquirer,  for shares of the
Company or for shares of the third  party  acquirer  having a value of twice the
right's then-current exercise price.

NOTE 11. Employee Equity Benefit Plans

Employee Stock  Purchase  Plan. In 1991,  the Company  adopted an Employee Stock
Purchase Plan ("PMC ESPP") under Section 423 of the Internal Revenue Code. Under
the PMC ESPP, the number of shares authorized to be available for issuance under
the plan are  increased  automatically  on  January  1 of each  year  until  the
expiration of the plan.  The increase will be limited to the lesser of (i) 1% of
the outstanding  shares on January 1 of each year, (ii) 2,000,000  shares (after
adjusting for stock dividends), or (iii) an amount to be determined by the Board
of Directors.

In 2000, in connection  with the acquisition of QED, the Company assumed the QED
Employee Stock  Purchase Plan ("QED ESPP").  A total of 115,000 shares of common
stock were  reserved for  issuance  under this Plan.  Under this Plan,  eligible
employees were able to purchase a limited amount of common stock at a minimum of
85% of the market value at certain  plan-defined dates. As of December 31, 2001,
all employees had converted to the PMC ESPP.

During 2002,  2001, and 2000,  there were 610,331 shares,  245,946  shares,  and
235,104 shares, respectively,  issued under the Plans at weighted-average prices
of $11.73, $31.93, and $16.21 per share, respectively. The weighted-average fair
value of the 2002,  2001,  and 2000  awards was $13.80,  $31.25,  and $41.90 per
share,  respectively.   During  2002,  an  additional  1,656,939  shares  became
available  under the PMC ESPP and no additional  shares were  authorized for the
QED ESPP. As of December 31, 2002,  5,834,285  shares were  available for future
issuance under the PMC ESPP.

Stock Option Plans. The Company has various stock option plans that cover grants
of options to purchase the Company's common stock. The options  generally expire
within five to ten years and vest over four years.

During 2000, the Company's  stockholders  elected to add a provision to the 1994
Incentive Stock Plan, under which plan most of the outstanding options have been
issued. Under the new terms, the number of shares authorized to be available for
issuance under the plan shall be increased  automatically on January 1, 2001 and
every year thereafter until January 1, 2004. The increase will be limited to the
lesser of (i) 5% of the  outstanding  shares on  January  1 of each  year,  (ii)
45,000,000  shares,  or  (iii)  an  amount  to be  determined  by the  Board  of
Directors.

In 2001, the company  simplified its plan structure.  The 2001 Stock Option Plan
(the "2001 Plan") was created to replace  certain  stock option plans assumed by
us in connection with mergers and acquisitions completed prior to 2001 (See Item
12). All option  activity  related to the 2001 Plan and all other  assumed plans
are included in the following tables.

Option activity under the option plans was as follows:

Voluntary  stock  option  exchange  offer.  On September  26, 2002,  the Company
completed  an offering  to all  eligible  option  holders of an  opportunity  to
voluntarily exchange certain stock options.

                                       72


Under the  program,  participants  were able to tender  for  cancellation  stock
options  granted  within the specified  period with exercise  prices at or above
$8.00 per share,  in exchange  for new options to be granted at least six months
and one day after the  cancellation  of the  tendered  options.  Pursuant to the
terms and conditions set forth in the Company's offer, each eligible participant
will  receive a new option to  purchase an  equivalent  number of PMC shares for
each  tendered  option  with an  exercise  price of less than  $60.00.  For each
tendered  option  with an  exercise  price  of  $60.00  or more,  each  eligible
participant  will  receive a new option to purchase a number of PMC shares equal
to one share for each four unexercised shares subject to the tendered option.

On September 26, 2002, the Company  accepted and cancelled 19.3 million  options
with  a  weighted  average  exercise  price  of  $35.98  and  expects  to  grant
approximately  16.5  million new  options no earlier  than March 27, 2003 and no

the closing price of the Company's common stock on the date of grant and will be
subject to a new vesting schedule.

At December 31, 2002,  the Company has  approximately  $583.4 million of federal
net operating losses, which will expire through 2022. Approximately $6.4 million
of the federal net operating losses is subject to ownership  change  limitations
provided  by  the  Internal   Revenue  Code  of  1986.   The  Company  also  has
approximately  $216.2  million  of state tax loss  carryforwards,  which  expire
through 2022. The utilization of a portion of these state losses is also subject
to  ownership  change  limitations  provided by the various  states'  income tax
legislation.

Included in the credit  carryforwards  are $18.9 million of federal research and
development  credits which expire through 2022,  $549,000 of foreign tax credits
which  expire in 2003,  $497,000  of  federal  AMT  credits  which  carryforward
indefinitely,  $11.1 million of state research and development  credits which do
not expire,  $1.3 million of state research and development credits which expire
through 2007, and $1.5 million of state manufacturer's  investment credits which
expire through 2012.

                                       74


Included in the above net  operating  loss  carryforwards  are $23.8 million and
$8.6 million of federal and state net operating  losses related to  acquisitions
accounted  for under the  purchase  method of  accounting.  The  benefit of such
losses,  if and when  realized,  will be  credited  first to  reduce to zero any
goodwill related to the respective  acquisition,  second to reduce to zero other
non-current intangible assets related to the respective  acquisition,  and third
to reduce income tax expense.

Included in the deferred tax assets before valuation allowance are approximately
$147.1 million of cumulative tax benefits related to equity transactions,  which

The pretax income (loss) from foreign  operations was ($32.6  million),  ($154.1
million) and $254.5 million in 2002, 2001, and 2000, respectively. Undistributed
earnings of the Company's foreign subsidiaries are considered to be indefinitely
reinvested and accordingly,  no provision for federal and state income taxes has
been provided  thereon.  Upon  distribution  of those  earnings in the form of a
dividend  or  otherwise,  the Company  would be subject to both US income  taxes
(subject to an adjustment for foreign tax credits) and withholding taxes payable
to the various foreign countries. It is not practical to estimate the income tax
liability that might be incurred on the remittance of such earnings.


NOTE 13.  Segment Information

The Company has two operating segments:  networking and non-networking products.
The networking  segment consists of  internetworking  semiconductor  devices and
related  technical  service and support to  equipment  manufacturers  for use in
their  communications  and  networking  equipment.  The  non-networking  segment
consists of custom  user  interface  products.  The  Company is  supporting  the
non-networking  products for existing customers,  but has decided not to develop
any further products of this type.

The accounting  policies of the segments are the same as those  described in the
summary of significant  accounting policies.  The Company evaluates  performance
based on gross profits from operations of the two segments.

Summarized financial information by segment is as follows:

(1)    In  connection  with the  voluntary  cancellation  of options to purchase
       approximately 19.3 million shares in September 2002, we promised to grant
       new options for  approximately  18.0 million  shares from our stock plans
       between  March 27, 2003 and April 30, 2003.  The new options will have an
       exercise price equal to the closing price of our common stock on the date
       they are  granted.  These  options  are  reflected  in the above chart as
       remaining  available  for  future  issuance.  As a  result  of  workforce
       reductions we currently  plan on issuing 16.5 million  options under this
       option  exchange   program  (See  Note  11  to   Consolidated   Financial
       Statements).

(3)    Includes  5,834,285  shares  available  for issuance in the 1991 Employee
       Stock Purchase  Plan. In January 2003, we issued 478,279 shares  relating
       to the purchase period that began in July 2002.

(4)    Consists of the 2001 Stock Option Plan (the "2001 Plan") and  outstanding
       options  that were  granted  pursuant  to assumed  stock  plans that were
       subsequently  made part of the 2001  Plan.  The 2001 Plan was  created to
       replace  certain  stock option  plans  assumed by us in  connection  with
       mergers and  acquisitions  completed prior to 2001. The number of options
       that may be granted  under the 2001 Plan  equals (i) the number of shares
       reserved  under the assumed  stock  option plans that were not subject to
       outstanding or exercised options  (1,830,641 shares) plus (ii) the number
       of options that were  outstanding  at the time the plans were assumed but
       that have subsequently been cancelled.

(5)    This table does not include information for stock option plans assumed by
       us which were not made part of the 2001 Plan or any outstanding warrants.
       As of  December  31,  2002,  a total of 48,398  shares of our stock  were
       issuable upon  exercise  under those other  assumed  plans.  The weighted
       average  exercise  price  of  those  outstanding  options  is  $4.55.  No
       additional  options may be granted under those plans.  As of December 31,
       2002,  warrants  to  purchase a total of 30,100  shares of our stock were
       outstanding with a weighted average price of $1.66.

ITEM 14.  Controls and Procedures

         Evaluation of disclosure controls and procedures

Our chief  executive  officer  and our chief  financial  officer  evaluated  our
"disclosure  controls  and  procedures"  (as  defined in Rule  13a-14(c)  of the
Securities Exchange Act of 1934 (the "Exchange Act") as of a date within 90 days
before the filing  date of this annual  report.  They  concluded  that as of the
evaluation date, our disclosure  controls and procedures are effective to ensure
that  information  we are required to disclose in reports that we file or submit
under the Exchange Act is recorded,  processed,  summarized and reported  within
the time periods  specified in the Securities and Exchange  Commission rules and
forms.

         Changes in internal controls

Subsequent to the date of their evaluation, there were no significant changes in
our internal controls or in other factors that could significantly  affect these
controls.  There were no significant  deficiencies or material weaknesses in our
internal controls so no corrective actions were taken.
