INDUSTRY OVERVIEW

During the 1990's, the Internet  experienced enormous growth as more households,
enterprises and corporations connected to and increased their utilization of the
Internet.  Traffic on the network  continued to increase due to a growing number
of  web-based  applications  (such  as  e-commerce,  e-mail,  videoconferencing,
webcasting,  virtual private networks and networked storage).  Higher volumes of
data are being  transmitted  between  local  area  networks  (LANs),  metro area
networks  (MANs)  and wide area  networks  (WANs) as a result of this  increased
connectivity and usage of the Internet.

The  growth  in  data  traffic  placed  increasing   pressure  on  the  existing
telecommunications network infrastructure , which was originally constructed for
voice  communication  rather  than  data  transmission.  Many  of the  incumbent
telephone  companies (such as AT&T, Sprint,  WorldCom,  NTT, British Telecom and
Deutsche  Telekom)  and  Regional  Bell  Operating  Companies  (such as Verizon,
BellSouth, and SBC) began investing in data networks to meet the growing demands
of their  customers.  At the same time,  deregulation of the  telecommunications
industry  and  privatization  of many  European  carriers  resulted in increased
market competition. The abundance of capital available in the public and private
markets also  accelerated  a build out of new network  infrastructure.  Numerous
competitive  carriers were launched with the intention of capturing  significant
share of (i)  long-haul  and  ultra  long-haul  data  traffic  (such  as  Global
Crossing,  Level 3, Williams); and (ii) the local/regional data markets (such as
Covad, Northpoint and RhythmsNet). This caused a significant increase in capital
spending on networking equipment by both the incumbent and competitive carriers.

During  this  period  of  rapid  expansion,  our  customers  - - the  networking
equipment companies ("OEMs") - - placed increased pressure on their suppliers to
ensure they had the components  needed to fulfill the expected growth in demand.
With many of the semiconductor  foundries at full capacity at the time, the OEMs
often  ordered  more devices  than  necessary in an attempt to secure  component
delivery.  This  resulted in inventory  levels  expanding at the OEMs,  contract
manufacturers, distributors and component suppliers at a faster rate than sales.

                                       3


This environment  changed suddenly at the end of 2000.  Capital markets began to
tighten,  many e-commerce  businesses  failed,  and the overall economy began to
slow  down.  Many  of the  competitive  carriers  who  were  unable  to  attract
sufficient customers to sustain their operations experienced financial hardship,
and in many cases were acquired or went into receivership. Many of the incumbent
carriers realized that increasing capital  expenditures on networking  equipment
as a percentage  of total  revenue was  unsustainable.  This resulted in a rapid
slowdown in total capital spending on networking  equipment across the industry,
which in turn  resulted in fewer  orders for our  customers'  equipment.  By the
first half of 2001,  most of our customers had  recognized  that rapid growth in
demand was over. As revenues declined, a large number of our customers announced
corporate   restructurings  and  inventory  write-downs  and  cancelled  various
equipment programs.

Due to this market  downturn,  we experienced a significant drop in sales of our
products.  The  impact  of the  downturn  was  magnified  by the high  levels of
inventory that existed at our distributors, the contract manufacturers,  and the
OEMs at the  beginning  of 2001.  As a result of the  decrease in demand for our
products, we implemented two restructuring plans in 2001. We announced the first
restructuring  in March 2001 when we terminated  223  employees,  consolidated a
number of facilities,  and cancelled certain development  projects. We announced
the second  restructuring  in October  2001 when we  terminated  341  employees,
consolidated   additional  facilities,   and  cancelled  additional  development
projects.   The  two  restructurings  reduced  our  workforce  by  approximately
one-third from our peak level in 2001. These  restructurings  have significantly
lowered our  operating  expenses and cost  structure  going  forward (for a more
detailed  description of the two  restructurings  see  "Restructuring  and other
special  charges" in the  Management's  Discussion and Analysis  section of this
report).

Despite the industry downturn,  Internet traffic  reportedly  continues to grow.
Industry  analysts  estimate that total data traffic on the Internet  could grow
annually   between  100%  and  300%  each  year.   Moreover,   the  adoption  of
next-generation  wireless  handsets  (providing voice as well as text messaging,
web connectivity,  and global  positioning) is expected to drive additional data
traffic through the network infrastructure in the future.

For many of the incumbent and regional service  providers,  data traffic and the
associated revenue remains a key growth driver for their operations.  To capture
a growing portion of this market, service providers are continuing to transition
their networks from voice-centric to data-centric systems. At the same time, the
market remains  competitive  as many cable and satellite  operators are offering
high-speed  connectivity  services as well. In this environment,  it is critical
for service  providers to build their  networks  with more  efficient  equipment
enabling them to lower operating  costs while handling the increasing  amount of
traffic.

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
data 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 in the form of  electrical  and  optical
signals  to  be  sent  and  received   reliably  and  efficiently  -  -  whether
intra-office, across the country, or internationally.

                                       4


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 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 being SDH or  Synchronous  Digital  Hierarchy.  Many of the  long-haul and
ultra long-haul fiber optic systems operate at higher speeds such as 10 gigabits
per second. In the metro area of the network,  signals are transmitted primarily
at rates between 155 megabits per second and 2.5 gigabits per second.

In addition to using SONET to increase  the  bandwidth in their  networks,  many
system  operators  have also  deployed  equipment  that uses 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 have increased capacity to
move more signals across transmission lines.

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. In general, less investment has been made to enhance the infrastructure in
the metro area and as a result, many of these systems have insufficient capacity
to handle the increased 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). While IP packets are larger and can hold more data than
ATM cells,  service providers can 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.

Another  protocol  that is used  extensively  in local area  networks and is now
being  deployed  in the wide area  network is  Ethernet.  Because  many  systems
operators are familiar with Ethernet, it is now transitioning into the wide area
of  the  network  at  higher  speeds  so  that  Ethernet  packets  can  be  sent
inter-office in a more efficient manner.

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

                                       5


By  leveraging  the  knowledge  and  technical  expertise of  companies  such as
PMC-Sierra, the OEMs are able to focus their efforts on differentiating factors.
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 the 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  solve the needs of
the service providers.


PRODUCTS

We  have  more  than  100  revenue-producing  products  in  our  portfolio.  Our
networking    products    are    communications    semiconductors,     including
microprocessors,  that are used in different  types of  equipment  that form the
internet  infrastructure.  Our  non-networking  segment is comprised of a single
chip used in a consumer medical device.

Networking Products

Our products are sold into three areas of the  telecommunications  network:  the
Access,  Metro  and  Enterprise  areas.  We  design  many of our  products  with
standardized  interfaces  between chips so that our customers can easily develop
and implement solutions involving multiple PMC-Sierra products.

The following briefly describes the Access, Metro and Enterprise portions 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 networking functions or markets. 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, while our
Paladin  chip may only be used in wireless  base station  applications.  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  technologies  that connect the home or office to the internet.
     This area includes wired and wireless networking  equipment that aggregates
     transmissions  from the home or office and  connects  to the metro and wide
     area  networks.  For  example,  our  devices  would be  deployed in 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).

o    Metro:  the  metro,  or  metro,  area  of the  internet  infrastructure  is
     predominantly a fiber-based network that provides high-speed communications
     and data transfer  over a city center or local region.  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.

                                       6


o    Enterprise: this area of the network includes equipment that is deployed in
     the home or office for data  communications  and other  local area  network
     applications. Our products are used in equipment such as networked printers
     in the office or home, as well as switches and storage  devices that enable
     data to be  transferred  to local  telecommunications  networks and storage
     area networks.

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 & 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 & cell  processors:  these devices  examine the contents of cells or
     packets and  performs  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 a customers' network usage and charge
     the appropriate service fee.

o    Traffic managers & 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.

o    Serializers/Deserializers:  these devices convert  networking  traffic from
     slower speed  parallel  streams  into higher speed serial  streams and visa
     versa.  OEMs  use  serial  streams  to  reduce  networking  equipment  line
     connections.  Conversely,  OEMs use  parallel  streams to allow them to use
     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.

Our products help OEMs both aggregate and  disaggregate  network traffic at high
and low speeds. As signals move through the network, carriers aggregate millions
of slow-speed  incoming signals through access devices into a few high-speed and
high-capacity  signals. For example,  slower-speed access lines such as T1 lines
(operating  at 1.54  megabits  per  second) are  aggregated  and  streamed  into
high-speed lines (such as optical  transmission at 2.5 gigabits per second). The
wide  range of  products  we make  operate  at  different  speeds in many of the
product categories listed above.

                                       7



Non-Networking Products

In 1996,  we announced our decision to  discontinue  the  development  of custom
non-networking chips. Our remaining  non-networking  product is still being sold
but no new development has been done since 1996. Our  non-networking  revenue is
generated by one custom  semiconductor device used to control the user interface
in a consumer health-monitoring device.


STRATEGY

Our  mission is to provide  superior  high-speed  internetworking  semiconductor
solutions to enable the restructuring of the global information  infrastructure.
We  facilitate  the upgrade on the  Internet  infrastructure  by  designing  and
selling   complex   chipset   solutions   based  on  our  knowledge  of  network
applications,  system  requirements  and  networking  protocols.  To achieve our
mission, we are pursuing the following key strategies:

Leverage technical expertise across diverse base of applications:

We have a history of analog,  digital,  microprocessor  and mixed signal  design
expertise and we integrate many  functions and protocols  into our products.  We
develop  chips that are used in a broad range of networking  equipment,  such as
multi-service  switches in the Access  portion of the  internet  infrastructure,
routers in the Metro portion and networked printers in Enterprise  networks.  We
leverage our common technologies and intellectual  property across a broad range
of networking equipment.

Many  OEMs  have   recognized   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.  By
outsourcing  more  of the  silicon  content  in  their  networking  and  telecom
equipment,  OEMs can improve their  time-to-market  and reduce  development risk
while differentiating their products in other ways.

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.  This places even
more  importance  on our  customer  service  efforts.  Customers  such as Cisco,
Lucent, Nortel,  Alcatel,  Samsung and Hewlett-Packard are aligning their design
and  manufacturing  operations  with  key  suppliers.  In 2001,  Cisco  selected
PMC-Sierra as its "Semiconductor  Supplier of the Year" and Lucent  Technologies
named us a strategic alliance partner.

Take a leading role in industry standards bodies and interoperability
initiatives:

                                       8


We continue to participate in many influential  industry  standards bodies so we
can assist in determining  performance criteria and  interoperability  standards
for the  industry.  This is critical to helping us make chips that our customers
will be able to deploy easily. In addition,  we work with the Saturn Development
Group (which we co-founded in 1992) to set new  interface  specifications.  As a
result of these efforts, our products enable interoperable solutions for a broad
range of  networking  applications.  To advance  this process  further,  we have
participated with other leading semiconductor  companies to demonstrate hardware
interoperability.  For example,  in 2001, we  collaborated  with Xilinx Inc. and
Altera Corp.  (industry  leading  suppliers of  programmable  logic  devices) to
successfully test the interoperability of our high-speed devices.

Maintain fabless business model:

We believe that  investing in the  research  and  development  of new devices is
strategically  more important  than trying to  differentiate  ourselves  through
manufacturing technologies. Consequently, we do not own or operate any foundries
and we design our  products  in  complementary  metal  oxide  silicon  (CMOS) at
feature  sizes  down to  0.13  micron.  We  outsource  approximately  90% of our
manufacturing  requirements  to Chartered  Semiconductor  Manufacturing,  Taiwan
Semiconductor  Manufacturing Corporation and IBM. By using independent foundries
to fabricate our wafers,  we are better able to concentrate our resources on the
design, development and testing of new products. In addition, we avoid having to
commit the capital required to own and operate a fabrication facility.

We  evaluate  our  performance  based on gross  profits  of the  networking  and
non-networking  segments.  For  information  concerning  revenues  and profit by
segment, see Note 13 to the Consolidated Financial Statements.


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 the rapidly  changing market of
the  telecommunications  industry.  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 more
complex devices need to be considered for the  application.  To assist us in our
planning  process,  we are in constant  contact  with our largest  customers  to
discuss industry trends,  emerging standards and their new product requirements.
Based on their input and our feedback,  we gain a better  understanding  of what
functions  and  features  they  want  integrated  into  our  chips  or chip  set
solutions.

                                       9


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 2001,  approximately 40% of our orders were
shipped by our  distributors;  approximately 40% were sent by us directly to the
contract manufacturers as selected by the OEMs; and the balance of the shipments
were sent directly by us to our OEM customers.

Our largest distributor is Memec Group Holdings Ltd. who represents our products
worldwide  (excluding  Japan). We believe that on a going-forward  basis many of
our customers will be seeking to reduce supply chain costs and will,  therefore,
request  that we ship more of our products to the  contract  manufacturers  they
have selected.  Based on this trend,  we expect that our largest  customers will
have us ship a  higher  percentage  of their  orders  directly  to the  contract
manufacturers  and a lower  percentage will be shipped through our  distributors
over time.

Cisco Systems and Lucent Technologies each represented more than 10% of our 2001
revenues based on total sales to end customers (i.e. based on shipments  through
our distributors, to the sub-contractors as selected by our customers, or to the
OEMs  directly).  Our sales  outside of the United  States  accounted for 42% of
total revenue in 2001, 38% in 2000, and 30% in 1999.


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 out to independent subcontractors.

We receive more than 90% of the silicon wafers with 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 the  designing,  development  and testing of new
products.  In addition,  we avoid much of the fixed capital cost associated with
owning and operating a fabrication facility.

                                       10


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, 2001 and 2000, we had $22 million and $23 million, respectively, 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  and Santa  Clara  facilities.  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.

We have design centers in the United States (California,  Oregon,  Maryland, and
Pennsylvania),  Canada  (British  Columbia,  Saskatchewan,  Ontario and Quebec),
Ireland, and India.

We spent $201.1  million in 2001,  $178.8  million in 2000, and $83.7 million in
1999 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,  2001,  our backlog of products
scheduled  for shipment  within six months  totaled  $35.7  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 2002.  Our backlog of products as of
December 31, 2000 for shipment within six months totaled $216 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.

                                       11



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 communications protocols,

o        interfaces easily with other components in a design,

o        meets power usage requirements, and

o        is priced competitively.

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 more aggressive price  competition from
competitors  that are  seeking  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.

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 qualified the supplier, as this ensures that components made
by that supplier will meet the OEM's strict 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,  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.

                                       12


Other  competitors  include  major  domestic  and  international   semiconductor
companies,  such as 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 wireless infrastructure and
generic  microprocessor  markets  that  have  established  incumbents  that have
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 112 U.S.  patents for circuit designs and other  innovations used in the
design  and  architecture  of our  products.  In  addition,  we have  94  patent
applications  pending in the U.S.  Patent  and  Trademark  office,  and 3 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 2020.

Our  products,  once  designed  are  outlined in mask works that  represent  the
predetermined    three-dimensional   pattern   of   metallic,   insulating,   or
semiconducting  material  present or removed from the layers of a  semiconductor
chip used to produce our product.  To protect our intellectual  property we rely
on a combination of mask work protection  under the Federal  Semiconductor  Chip
Protection Act of 1984, trademarks,  copyrights, trade secret laws, employee and
third-party nondisclosure agreements and licensing arrangements.

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.

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 MIPSA 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.

ITEM 2.  Properties.

PMC leases or owns properties in twenty-six locations  worldwide.  Approximately
45% of  the  space  leased  by PMC is  currently  unoccupied.  Pending  sublease
transactions  and lease  expiries will reduce the excess,  uncommitted  space to
39%.

We lease a total of 462,000  square feet in seven  separate  buildings  in Santa
Clara, California, to house the majority of our US design, engineering,  product
test, sales and marketing operations.

Our Canadian  headquarters  are located in Burnaby,  British  Columbia  where we
lease  254,000  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 twelve 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
intention of building our own  facility to replace our existing  leased  Burnaby
premises.

Comparison of Fiscal 2001, 2000 and 1999

Net Revenues ($000,000)



                                 2001       Change      2000       Change      1999

Networking products             $ 300.2     (55%)      $ 665.7      139%      $ 278.5

Non-networking products         $  22.5     (22%)      $  29.0       68%      $  17.3

Total net revenues              $ 322.7     (54%)      $ 694.7      135%      $ 295.8


Net revenues for 2001 decreased by $372.0 million,  or 54%, from net revenues in
2000.  In contrast,  net revenues for 2000 were higher than net revenues in 1999
by $398.9 million, or 135%.

         Networking

Our networking  revenues declined 55% in 2001 due to decreased unit sales of our
networking  products  caused by reduced demand for our  customers'  products and
excess  inventories  of our products  accumulated  by our customers in the prior
year.  Also included in the 55% decline in networking  revenues was a 5% decline
in the selling price of our products.

2000 networking  revenues were 139% higher than networking  revenues in 1999 due
to an  increase  in  customer  demand  that  resulted  from  the  growth  of our
customers' networking equipment businesses,  our customers' continued transition
from internally developed  application  specific  semiconductors to our standard
semiconductors,  our introduction and sale of networking products that addressed
additional  network  functions,  and a  significant  increase in our  customers'
inventory of our products.

         Non-networking

Non-networking  revenues  declined 22% in 2001 compared to an increase of 68% in
2000.  These  changes  reflect  the volume of  purchases  made by our  principal
customer in this segment.  In 1996,  we  discontinued  development  of follow-on
products in this  segment  and we are now only  fulfilling  customer  orders for
previously developed products.

 Percentage of net revenues                57%                    76%                    75%


Total gross profit for 2001  decreased  by $343.0  million,  or 65%,  from gross
profit in 2000.  In contrast,  2000 gross profit was higher than gross profit in
1999 by $306.2 million, or 138%.

         Networking

Our networking  gross profit  decreased by $339.6  million in 2001.  Over 80% of
this dollar decrease was due to the reduction in our networking sales volume.

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.

The $20.7 million write-down for excess inventory,  which we recorded in cost of
revenues,  consisted of a $2.1 million charge in response to the cancellation of
certain of our customers'  programs plus a charge of $18.6 million for inventory
levels in excess of estimated 12-month demand (see "Critical Accounting Policies
and Significant Estimates").

Our networking gross profit increased by $301.3 million in 2000 due to increased
sales volumes but did not change as a percentage of networking  revenues between
1999 and 2000.

         Non-networking

Non-networking gross profit as a percentage of non-networking revenues decreased
to 42% in 2001  from  44% in 2000  and 46% in  1999  due to a  reduction  in the
selling price of our non-networking product.

         Research and Development Expenses

Our research and  development,  or R&D,  expenses  were $201.1  million in 2001,
$178.8  million in 2000,  and $83.7  million in 1999, an increase of 12% in 2001
compared to 2000 and an increase of 114% in 2000 compared to 1999.

R&D expenses  for 2001 were 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.
(See "Restructuring and other special charges".)

Although we  implemented  two  restructuring  plans  during the first and fourth
quarters  of  2001,  our  total  R&D  expenses  increased  because  we had  made
substantial  additions to our personnel and tools during the latter part of 2000
and we have  realized  less  than 3  months'  savings  from  our  fourth-quarter
restructuring. While we reduced our R&D personnel by 34% by the end of 2001 from
the end of 2000,  our  personnel  and related  costs for 2001  exceeded  2000 by
approximately  $7.2 million.  We also increased our tools and equipment costs by
$11.8  million due to our  continued  investment  in new tools and  equipment in
support of our continuing research and development efforts.

Our 2001 R&D expenses also increased by $4.2 million as a result of acquisitions
that we completed during 2000 and accounted for under the purchase method.

                                       21


In 2000, our R&D expenditures increased by 114% over 1999 due to a $51.5 million
increase  in  personnel  and related  costs as a result of  internal  hiring and
acquisitions,  and a $36.1  million  increase  in  service  and  material  costs
associated with our expanding product development efforts. Our 2000 R&D expenses
also  increased  by $7.4 million as a result of  acquisitions  that we completed
during 2000 and accounted for under the purchase method.

Our R&D expenses  increased  as a percentage  of net revenues in 2001 due to the
54% decline in our 2001 net revenues.  The expenses decreased as a percentage of
net  revenues  in 2000 as a result of the 139% growth in our net  revenues  that
year.


         Marketing, General and Administrative Expenses

Our marketing, general and administrative, or MG&A, expenses decreased by 10% to
$90.3 million in 2001 from $100.6 million in 2000.

The $10.3 million decrease in our MG&A expenses was largely due to a $12 million
reduction in sales commissions as a result of the decline in our revenues.  MG&A
expenses increased by approximately $1.2 million in 2001 as a result of the full
year impact of  acquisitions  made during 2000 that were accounted for under the
purchase method.

Through our two restructuring programs in 2001, we reduced our MG&A personnel by
30% from the end of the  preceding  year.  However,  due to growth in the latter
part  of  2000,  this  reduction  in  MG&A  personnel  resulted  in  only  a  3%
year-over-year decrease in MG&A personnel costs.  Recruitment costs decreased in
2001 due to less hiring activity.  These savings were offset by increases in the
cost  of  facilities  due to the  prior  year's  expansion.  Our  restructurings
resulted  in  excess  space  when  we  reduced  our  personnel  in  2001.   (See
"Restructuring and other special charges".)

Our MG&A  spending in 2000  increased  92% from 1999.  In 2000, we increased our
personnel and  recruitment  costs by $20 million and expanded our facilities and
related costs by more than $8 million due to the addition of new  personnel.  We
also  increased  the size of our direct sales force in 2000 and  incurred  $10.7
million more in commissions as a result of our increased revenues. MG&A expenses
also increased by approximately $1.8 million in 2000 as a result of acquisitions
made during 2000 that were accounted for under the purchase method.

MG&A expenses as a percentage of net revenues increased in 2001 and decreased in
2000 because many of our MG&A costs are relatively fixed in the short term. As a
result,  these  expenses  will  generally  decline as a percentage of revenue in
periods  of rising  revenues  and may  increase  as a  percentage  of revenue in
periods of declining revenues.

                                       22


         Amortization of Deferred Stock Compensation

We recorded total deferred stock  compensation  expense of $41.2 million in 2001
compared to $36.3 million in 2000 and $5.1 million in 1999.

In 2001, our amortization of deferred stock  compensation  increased compared to
2000 due to accelerated  vesting  related to certain  employees  terminated as a
result of our two restructurings.

Our acquisitions of AANetcom,  Abrizio,  QED,  SwitchOn,  Toucan, and Extreme in
2000 contributed  $16.2 million to deferred stock  compensation  amortization in
2000 and all of the expense in 1999. An additional, $20.1 million of the expense
in 2000 related to the unearned  compensation  recognized  on the  Malleable and
Datum purchase acquisitions.


         Amortization of Goodwill and Impairment of Intangibles

Non-cash  goodwill charges increased to $44.0 million in 2001 from $36.4 million
in 2000 and $1.9 million in 1999 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 do not expect to have any
future cash flows related to the Malleable  assets and have 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 the year.


         Costs of Merger

We did not make any pooling acquisitions and therefore, did not incur any merger
costs in 2001.

In 2000, we completed  five pooling  acquisitions  and incurred $38.0 million of
merger costs.  In 1999, we completed one pooling  acquisition  and incurred $0.9
million of merger costs.  These charges consist primarily of investment  banking
and other professional fees.


                                       23



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

IPR&D charges were $38.2 million in 2000. There were no IPR&D charges in 2001 or
1999.

The amounts  expensed to in process  research and development in 2000 arose from
the acquisitions of Malleable and Datum. We did not make any  acquisitions  that
were accounted for using the purchase method in 2001 or 1999.

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% and
30% for Malleable and Datum, respectively.

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.

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.

                                       24


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 the  introduction  of the third  generation  base stations into which we
expect to  incorporate  our  technology,  but we expect these  products to begin
generating revenues in the second quarter of 2002.

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").


         Restructuring and other special charges

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.  Prior to the end of the first quarter,
management  approved the restructuring plan committing PMC to the termination of
223 employees,  the  consolidation of a number of facilities and the curtailment
of certain research and development  projects.  Employees  terminated under this
plan were advised prior to the end of the quarter of the termination benefits to
which they were entitled.

                                       25


The elements of the accrued restructuring costs related to the March 2001
restructuring plan are as follows:

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


Workforce  reduction  includes the cost of severance and related benefits of 223
employees affected by the  restructuring.  These terminations were spread across
all  business  functions,  with  approximately  70%  occurring  in Research  and
Development and the remainder  occurring in Sales,  Marketing and Administrative
and Production departments.

Facility  lease and contract  settlement  costs include:  (i) lease  termination
payments and other costs related to the closure of certain corporate facilities,
sales offices and research and development centers for activities that have been
exited or restructured;  and (ii) penalties  incurred due to our withdrawal from
certain purchase contracts.

Certain  leasehold  improvements  located at the closed  facilities and computer
equipment and software  licenses  were  determined to be impaired as a result of
the  restructuring  activities  and were written  down to estimated  fair market
value, net of disposal costs.

We expect to complete the  restructuring  activities  contemplated  in the March
2001  plan by the end of March  2002.  Upon  conclusion  of these  restructuring
activities,  we expect to  achieve  annualized  savings of  approximately  $28.2
million in cost of revenues and operating expenses.


Restructuring - October 18, 2001

Due to the  continued  decline in market  conditions,  we  implemented  a second
restructuring  plan in the fourth  quarter of 2001 to reduce our operating  cost
structure.  Prior to the end of the  fourth  quarter,  management  approved  the
second  restructuring  plan  committing PMC to the termination of 341 employees,
the  consolidation  of additional  excess  facilities,  and the  curtailment  of
additional research and development  projects.  Employees  terminated under this
plan were advised prior to the end of the quarter of the termination benefits to
which they were entitled. As a result, we recorded a second restructuring charge
of $175.3 million in our fourth quarter.

                                       26


The  elements of the accrued  restructuring  costs  related to the October  2001
restructuring plan are as follows:

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


Workforce  reduction  includes the cost of severance and related benefits of 341
employees affected by the  restructuring.  These terminations were spread across
all  business  functions,  with  approximately  64%  occurring  in Research  and
Development and the remainder  occurring in Sales,  Marketing and Administrative
and Production departments.

Facility lease and contract settlement costs include:  (i) lease termination and
other costs  related to the closure of corporate  facilities as a result of this
restructuring;  and (ii) penalties  incurred due to our withdrawal  from certain
purchase contracts. A significant component of this charge for excess facilities
relates to a 10-year Santa Clara,  CA building  lease  committed to in 2000. The
charge for this  excess  facility is recorded  net of expected  future  sublease
revenue. See "Critical Accounting Policies and Significant Estimates".

Certain  leasehold  improvements  located at the closed  facilities and computer
equipment,  software licenses, and related software maintenance prepayments were
written down to estimated fair market value, net of disposal costs.

We expect to complete the restructuring  activities  contemplated in the October
2001  restructuring plan by the fourth quarter of 2002. Upon conclusion of these
restructuring  activities, we expect to achieve additional annualized savings of
approximately $67.6 million in cost of revenues and operating expenses.

Net interest and other income declined in 2001 by $5.0 million, or 26%.

                                       27


Excluding  interest  expense  and  the  amortization  of debt  financing  costs,
interest  and other  income  for 2001 was $19.0  million  as  compared  to $19.8
million in 2000. The amount for 2000 included  income of $0.6 million related to
an investee  accounted for under the equity  method 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,  or "cash
balances",  this  decline was offset by an  additional  $3.0 million in interest
income from an overall increase in our cash balances.

Our interest expense increased to $4.3 million in 2001 from $0.8 million in 2000
as a result of the  interest  expense  incurred on  convertible  notes issued in
August 2001 (see "Liquidity and Capital  Resources"  below). We also incurred an
incremental  $0.6 million in amortized debt issuance costs incurred in 2001 as a
result of the issuance of our convertible notes.

Our net interest income increased in 2000 compared to 1999 as a result of higher
cash balances available to earn interest. Other income in 2000 and 1999 included
income  from an equity  interest  in another  company of $0.6  million  and $0.8
million,  respectively.  We  decreased  interest  expense from loans and capital
leases to $0.8 million in 2000 from $1.5  million in 1999 by retiring  debt from
loans and capital leases.

We reported a net loss on  investments  of $14.6  million in 2001,  and gains on
investments of $58.5 million in 2000 and $26.8 million in 1999.

In 2001,  we  recorded  $2.9  million  of gains on the sale of a portion  of our
investment  in  Sierra  Wireless,  Inc.,  a  public  company,  as well as  other
investments.  These gains were 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  resulted  from the sale of a  portion  of our
investment in Sierra Wireless,  Inc. Additionally,  we sold our remaining shares
of Cypress Semiconductor, Inc. resulting in a gain of $4.1 million.

In 1999,  we recorded  gains of $14.5  million from the sale of a portion of our
Sierra Wireless shares.  During the year, we also had an investment in IC Works,
Inc.,  or ICW, a private  company  that was  subsequently  purchased  by Cypress
Semiconductor,  a public company. As a result of that transaction,  we exchanged
our  preferred  shares of ICW for  common  shares of Cypress  Semiconductor.  We
disposed  of a portion of our shares in Cypress  Semiconductor,  resulting  in a
gain of $12.3 million.


         Provision for Income Taxes.

                                       28


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,  and impairment of purchased intangibles,  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 as a result of a valuation  allowance  provided on deferred tax assets that
were uncertain of being realized.

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.

Our annual  effective  tax rate for the year ended  December 31, 1999 was 36.5%,
which approximated the statutory tax rate of 35%.

We have  provided a valuation  allowance  on certain of our  deferred tax assets
because of uncertainty regarding their realizability.

See Note 12 to the Consolidated  Financial Statements for additional information
regarding income taxes.


         Recently issued accounting standards.

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.  SFAS  142
requires goodwill to be allocated to, and assessed as part of, a reporting unit.
Further,  SFAS 142  specifies  that  goodwill  will no longer be  amortized  but
instead will be subject to impairment  tests at least  annually.  The impairment
test is a  two-step  process.  First,  the  fair  value of a  reporting  unit is
compared to its carrying  value to identify  possible  impairment  and then,  if
necessary,   the  impairment  is  measured   through  a  deemed  purchase  price
allocation.  Under this standard,  we will also be required to review the useful
lives of acquired goodwill and intangible assets at least annually.

We will adopt SFAS 141 and 142 on a prospective basis as of January 1, 2002. The
adoption of SFAS 141 is not expected to have a material  effect on our financial
position,  results of  operations  and cash flows unless we acquire  significant
additional companies.

In 2002,  we will no longer  amortize  goodwill  pursuant  to SFAS 142,  thereby
eliminating annual goodwill amortization of approximately $2.0 million. Goodwill
amortization for the year ended December 31, 2001 was $44.0 million. Unamortized
goodwill as of December 31, 2001 was $7.1  million.  We will complete an initial
goodwill  impairment  assessment in the second quarter of 2002 to determine if a
transition impairment charge should be recognized under SFAS 142.

In October 2001, the FASB issued Statement of Financial  Accounting Standard No.
144 (SFAS  144),  "Accounting  for the  Impairment  or  Disposal  of  Long-Lived
Assets".  SFAS 144 supersedes Statement of Financial Accounting Standard No. 121
(SFAS  121),  "Accounting  for  the  Impairment  of  Long-Lived  Assets  and for
Long-Lived Assets to Be Disposed Of" and the accounting and reporting provisions
of APB  Opinion  No.  30 for  the  disposal  of a  business  segment.  SFAS  144
establishes a single  accounting  model,  based on the framework  established in
SFAS 121, for  long-lived  assets to be disposed of by sale.  The Statement also
broadens the presentation of discontinued  operations to include  disposals of a
component  of an entity and provides  additional  implementation  guidance  with
respect to the  classification of assets as held-for-sale and the calculation of
an impairment loss. We are required to adopt SFAS 144 effective January 1, 2002.
We do not  expect  the  adoption  of SFAS 144 to have a  material  impact on our
financial statements.


Critical Accounting Policies and Significant Estimates

         Our significant  accounting policies are outlined within Item 8 as Note
1 to the Financial  Statements and Supplementary  Data. Some of those accounting
policies  require us to make estimates and  assumptions  that affect the amounts
reported by us. The following  items require the most  significant  judgment and
involve complex estimation:

         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,
and the timing and rate at which we might be able to sublease the 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.  We
recorded a charge of $155 million for the  restructuring of excess facilities as
part of the  restructuring  plan, which was  approximately  53% of the estimated
total  future   operating  cost  and  lease  obligation  for  those  sites.  Our
assumptions  on either the lease  termination  payments,  operating  costs until
terminated, or the 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 2001,  our  inventory of
networking  products exceeded  estimated 12-month demand by $20.7 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.

         Income Taxes

                                       30


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.

         Goodwill

As part of our restructuring  plan, we discontinued  further  development of the
technology acquired in the purchase of Malleable Technologies, Inc. We estimated
that we would not  receive any future cash flows  related to these  assets,  and
recorded an  impairment  of the  remaining  net book value of the  goodwill  and
intangible assets related to Malleable of $189 million.

We also performed a review of the technology and assets acquired in the purchase
of Datum Telegraphic, Inc. We estimated the future cash flows of those assets in
light of continued weak industry  conditions,  lower market growth expectations,
and delays in our customers' clients moving to next generation wireless services
where the Datum technology can be used. Based on the discounted  values of those
cash flows,  we recorded an impairment  charge of $79.3 million of the remaining
net book value of goodwill and intangible  assets  related to Datum.  Failure to
achieve the revised levels of revenues and net income will negatively impact the
revised  return on  investment  and may  result  in  further  impairment  of the
goodwill and purchased intangible assets related to Datum.

         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 $17.5  million in the fourth  quarter of 2001.  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 $12.4 million investment.

                                       31


Business Outlook

Our networking revenues declined in 2001 compared to 2000 because:

o    in reaction to lower than expected  demand for network  services and rising
     debt  levels,  network  service  providers  spent  less  on the  networking
     equipment  that  our  customers  sell  and  which  include  our  networking
     products, and

o    our customers  consumed a portion of the significant  excess inventories of
     our networking products that they accumulated in 2000 and the first quarter
     of 2001.

Most of our networking  customers'  clients have announced  further  anticipated
declines in expenditures on our customers'  equipment and some have either filed
or will soon file for bankruptcy  protection.  Most of our customers continue to
restructure  their  operations,  cut significant  product  development  efforts,
reduce their excess component inventories, and divest parts of their operations.

While we expect the  networking  equipment  industry  downturn to continue  into
2002,  we believe  that our  customers  and their  contract  manufacturers  have
depleted a significant portion of their inventories of our networking  products.
In addition,  we believe our customers have designed more of our next generation
networking  semiconductors  into  their  equipment  than in  prior  years.  This
suggests that our networking  revenues will  stabilize in 2002,  albeit at lower
levels than in 2001. We expect to experience  quarterly sequential growth in the
first quarter of 2002.  We expect that the pattern of our  quarterly  networking
revenues  to be  volatile  in 2002 as a result of  fluctuating  customer  demand
forecasts and inventory levels. At any time our networking  revenues may decline
further if our customers' clients announce further reductions in spending on our
customers'  equipment.  Recent  news  releases  indicate  that  network  service
providers continue to struggle financially and may further decrease expenditures
on our customers' products.

We expect sales of our  non-networking  device to decline  significantly  by the
second  quarter  of 2002 as the  next  generation  product  that  our  principal
customer has designed no longer incorporates our non-networking device.

We expect our total R&D and MG&A expenses to decline in 2002 as compared to 2001
as a result of the two restructurings we undertook in 2001. We estimate that our
quarterly overhead expenses will be in the mid $50 million range,  excluding any
special charges, for the foreseeable future.

In July 2001,  the  Financial  Accounting  Standards  Board issued  Statement of
Financial  Accounting Standard No.142 (SFAS 142), "Goodwill and Other Intangible
Assets".  SFAS 142  specifies  that  goodwill  will no longer be  amortized  but
instead  will be  subject to  impairment  tests at least  annually.  We will not
amortize  goodwill  in 2002.  We will  complete an initial  goodwill  impairment
assessment in the second quarter of 2002 to determine if a transition impairment
charge should be recognized under SFAS 142.

We anticipate that interest and other income will decline  significantly in 2002
as compared to 2001 because we expect to earn lower  average  yields on our cash
balances and expect to consume cash throughout 2002 for operations.

                                       32



Liquidity and Capital Resources

We have no special  purpose  entities and no undisclosed  borrowings or debt. 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 contribute only cash to our employees' 401 K and other pension plans.

Our  principal  source of  liquidity  at December  31,  2001 was our cash,  cash
equivalents and short-term  investments of $410.7 million,  which increased from
$375.1 million at the end of 2000. At the end of 2001, we also held $171 million
in investments in bonds and notes with maturities  between 12 and 30 months.  We
had no such investments at the end of 2000.

During 2001,  we used $53.2 million in cash for  operating  activities.  Our net
loss  of  $639.1  million  included  non-cash  charges  of  $269.8  million  for
impairment of intangible assets,  $46.8 million for amortization of intangibles,
$51.2 million for depreciation, $41.2 million for amortization of deferred stock
compensation,  $20.7  million  for an  excess  inventory  write-down,  $17.5 for
impairment of other  investments,  and $16.2  million of non-cash  restructuring
costs.  In  addition,  we  recognized  $2.9  million  of  gains  on the  sale of
investments.

With respect to changes in working capital,  we generated cash by decreasing our
accounts  receivable by $77.8 million and our prepaid  expenses by $6.1 million.
We used cash to decrease our  accounts  payable and accrued  liabilities  by $30
million,  deferred  income by $36.4  million and income  taxes  payable by $43.7
million.  By the end of 2001,  we had $161.2  million  in accrued  restructuring
costs that we expect will consume cash in future periods.

Our year to date investing  activities  include the maturity of and reinvestment
in short-term  investments.  We also invested  $197.1 million in bonds and notes
with  maturities  between  12  and  30  months,  $26.1  million  of  which  were
reclassified  as short-term  investments at the end of 2001. We purchased  $27.8
million of property and equipment, $4.2 million in other investments and assets,
net of sales, and reduced total wafer fabrication deposits by $1 million.

Our financing  activities in 2001 generated  $290.2  million.  We received $24.8
million of proceeds from issuing common stock upon exercise of stock options and
used $1.7 million for debt and capital lease repayments  during 2001. In 2001 we
received net proceeds of $267.2 million by issuing $275.0 million of convertible
subordinated  notes. The notes are subordinated to all of our senior debt, pay a
3.75% coupon of approximately  $5.2 million on February 15 and August 15 of each
year,  and mature on August 15, 2006. The notes are  convertible  into shares of
our common stock at a conversion  price of  approximately  $42.43 per share, and
are subject to restrictive  covenants including those concerning payments on the
notes and other  indebtedness.  In the event of a change in control of PMC,  the
noteholders may require us to repurchase their notes.

We have a line of credit  with a bank that allows us to borrow up to $25 million
provided,  along with other  restrictions,  that we do not pay cash dividends or
make any material  divestments  without the bank's written consent.  At December
31, 2001, we committed approximately $5.3 million of this facility under letters
of credit as  security  for a leased  facility.  These  letters of credit  renew
automatically each year and expire in 2011.

                                       33


We have commitments made up of the following:

In connection with the  restructuring  plans  implemented in 2001, we recorded a
charge of $128.3 million for exiting and terminating  operating lease facilities
included in the above table.

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 $40.7 million into these funds,  which
may be requested by the fund managers at any time over the next eight years.

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 2002. We
expect to spend approximately $25 million on new capital additions during 2002.


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.

                                       34


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 2002.

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.  Recent news  releases
further indicate that carriers continue to struggle  financially and may further
decrease expenditures on our customers' products.

Consequently,   most  of  our  customers'  clients  have  announced  significant
reductions in current and forecasted expenditures on the equipment our customers
sell and have adjusted these  expenditures  toward  equipment which may generate
financial return in a shorter time horizon.  This equipment 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.  Consequently,  they have  canceled or  rescheduled  orders for our
networking products. 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 beyond 2001 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.  In addition,
because some of our costs are fixed in the short term,  the  reduction in demand
for our products has caused our gross and net profit margins to decline.

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,  will continue to depress revenues and profit margins beyond
2001 (see "Business  Outlook" above). We cannot  accurately  predict when demand
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.

                                       35


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.

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  networking  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  occasionally  estimate the size and  consumption  of our customers'
         inventories of our products.  These  estimates are based on our limited
         survey of selected  contract  manufacturers  and our  largest  original
         equipment  manufacturer,  or OEM,  customers.  Our analysis is intended
         only to provide us with some information  about our market to assist in
         our  forecasts,  which  are  limited  by the  precision  of the data we
         obtain.

o    Our  surveys are not  comprehensive.  For  instance,  we do not include all
     contract  manufacturers  or most of our  other  customers,  so our  overall
     estimates may be understated and we cannot  accurately  forecast  inventory
     consumption by these customers.

o    We are unable to obtain  accurate  data from survey  respondents  about the
     degree to which our  products  are  included in their work in progress  and
     finished goods  inventories,  so our estimates of their  inventories of our
     products may be understated.

o    We do not  verify  or  crosscheck  the  information  we  receive  from  the
     companies we survey.

o    We obtain  this  information  over  extended  periods and do not adjust the
     information for the time at which a response was received.

While we  intend  to  monitor  contract  manufacturer  and  large  OEM  customer
inventories  of our  products,  we may not do this  consistently  and we may not
provide updates of our expectations resulting from new data we obtain.

Even  if our  survey  proves  accurate,  our  estimate  of when  these  contract
manufacturers and large OEM customers will consume their inventory and return to
purchasing products from us may not be accurate for the following reasons:

o    Contract  manufacturers  and  OEMs who  consume  their  inventories  of our
     products may buy units from our distributors'  existing  inventories before
     they start buying  additional  units from us. While we will recognize sales
     by our  major  distributor  as  revenue,  those  sales  will not  result in
     additional cash flow.

                                       36


o    Customer inventory  consumption may not correlate with purchases of product
     from  our  inventories  or the  inventories  of our  distributors.  The PMC
     products  that  our  customers   require  may  shift  as  the  technologies
     underlying their new products evolve.

         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
Lucent  Technologies  each  accounted  for  more  than  10% of our  fiscal  2001
revenues.  Both of these companies have recently  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 2001 we  recorded  an  inventory  write-down  of $20.7
million related to excess inventory on hand. The inventory  reserve was based on
our revenue expectations through 2002. If future demand of our products does not
meet  our  expectations,  we may  need  to  take  an  additional  write-down  of
inventory.

         If  the  recent  trend  of  consolidation  in the  networking  industry
         continues, many of our customers may be acquired, sold or may choose to
         restructure  their  operations,  which  could lead those  customers  to
         cancel  product lines or  development  projects and our revenues  could
         decline.

The networking  equipment  industry is experiencing  significant merger activity
and partnership programs.  Through mergers or partnerships,  our customers could
seek to remove  duplication  or overlap in their  product  lines or  development
initiatives.  This could lead to the  cancellation  of a product line into which
our  products  are   designed  or  a   development   project  in  which  we  are
participating. In the case of a product line cancellation, our revenues could be
negatively impacted. In the case of a development project  cancellation,  we may
be  forced to cancel  development  of one or more  products,  which  could  mean
opportunities  for future  revenues from this  development  initiative  could be
lost.

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

                                       37


We have  announced a large  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 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  which 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.

On March 26 and  October  18,  2001,  we  announced  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,  which  represents  management's  best  estimate,  and which  may  require
adjustment in the future.

We implemented  this  restructuring in an effort to bring our expenses into line
with our reduced  revenue  expectations.  However,  for at least 2002, 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.

Restructuring plans require significant  management  resources to execute and we
may fail to achieve our targeted goals. 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:

                                       38


         As our  customers  increase the  frequency  with which they design next
         generation  systems  and  select the chips for those new  systems,  our
         competitors have an increased  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,  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.

Other  competitors  include  major  domestic  and  international   semiconductor
companies,  such as 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.

                                       39


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 rapidly  evolving  industry
         standards  and  customer  specifications,  which may  prevent  or delay
         future revenue growth.

We sell  products to a market whose  characteristics  include  rapidly  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.


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
receivership or breach debt covenants, our significant accounts receivables with
these companies could be jeopardized.


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

                                       40


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.


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, 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.


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.

                                       41


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.


A significant  portion of our revenues is derived from sales of  microprocessors
based on the MIPS architecture that we license from MIPS  Technologies,  Inc. If
MIPS Technologies  develops future generations of its technology,  we may not be
able to obtain a license on reasonable terms.

Our only material license is the MIPS microprocessor  architecture  license from
MIPS   Technologies   Inc.,   which   we   use  in   the   development   of  our
microprocessor-based  products.  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 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.  If we fail to comply  with any of the
terms of its license  agreement,  MIPS Technologies  could terminate our rights,
preventing us from marketing our current and planned microprocessor products.


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.

                                       42


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.

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.

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.  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.

                                       43


         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.


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.

                                       44


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.

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, as well as 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.

                                       45


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.

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  leverage  as a  result  of the  sale of
convertible 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.

                                       46


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.

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.

                                       47



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 less than 15% of our investment portfolio as of December
31, 2001.

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.

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, 2001 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  $2.6
million, $5.3 million and $7.9 million respectively.

         Other Investments:

Other  investments  at  December  31,  2001  include a  minority  investment  of
approximately  2.3 million  shares of Sierra  Wireless  Inc., a publicly  traded
company. This investment is subject to certain resale restrictions.  1.2 million
shares will be released  from these  restrictions  in May 2002 and the remaining
shares  are  currently  classified  as  available-for-sale.   Consequently,  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 regularly  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, 2001,  we held  approximately  85,000
shares of Intel Corporation. It is our intention to sell these securities in the
first quarter of 2002.

                                       48


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 2001, we recorded an impairment of our other  investments  of
$17.5 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.

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 utilize this method of managing our foreign  currency risk in
the future,  we may change our foreign currency risk management  methodology and
utilize  foreign  exchange  contracts  that are  currently  available  under our
operating line of credit agreement.

We  regularly  analyze the  sensitivity  of our foreign  exchange  positions  to
measure our foreign  exchange risk. At December 31, 2001, 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.

                                       49


         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.  The fair  value of the  convertible  subordinated  notes at
December  31,  2001 was not  readily  determinable  as there was no  established
public trading market for the notes. Some of the convertible  subordinated notes
have been traded 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,  the figures  recorded are not  independently  verified and the
information only reflects the trades of pre-qualified Portal dealers.

Independent Auditors Report

The Board of Directors of PMC-Sierra, Inc.

We have audited the accompanying consolidated balance sheets of PMC-Sierra, Inc.
as of  December  31, 2001 and 2000 and the related  consolidated  statements  of
operations,  stockholders'  equity and cash flows for each of the three years in
the period  ended  December  31, 2001.  Our audits also  included the  financial
statement  schedule  listed  in the  index  at Item  14(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. at
December 31, 2001 and 2000, and the  consolidated  results of its operations and
its cash flows for each of the three  years in the  period  ended  December  31,
2001, in conformity with accounting  principles generally accepted in the United
States of  America.  Also,  in our  opinion,  the  related  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.

NOTE 1.   Summary of Significant Accounting Policies

Description  of business.  PMC-Sierra,  Inc (the  "Company" or  "PMC-Sierra"  or
"PMC") designs,  develops,  markets and supports high-performance  semiconductor
networking  solutions.  The  Company's  products  are  used  in  the  high-speed
transmission  and networking  systems,  which are being used to restructure  the
global telecommunications and data communications infrastructure.

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  2001 and 1999  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  or  remaining
maturities greater than 90 days, but less than one year.  Long-term  investments
are defined as bonds and notes with  original or  remaining  maturities  greater
than 365 days. Any long-term investments 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. Unrealized gains and losses on these investments,  net of any related tax
effect are included in equity as a separate component of stockholders' equity.

The cost of securities sold is based on the specific  identification method. The
proceeds  from  sales  and  realized  gains or  losses  on  sales of  short-term
investments classified as available-for-sale  securities for all years presented
were immaterial.

                                       57



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.

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 as at  December  31,  2000 and 2001,  held less than 20% of the  voting
rights of the 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 (2000 - $23.0  million) to secure access to wafer  fabrication
capacity.  During 2001, the Company  purchased  $42.7 million ($81.1 million and
$30.5 million in 2000 and 1999, 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 2001  purchases,  the
Company is not entitled to a refund from these suppliers in 2002. 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 at the
termination of the agreements.

                                       58


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.

The components of property and equipment are as follows:

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

The components of goodwill and other intangible  assets,  net of write-downs for

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 periodically reviews its long-lived
assets and certain  intangible assets 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 or certain  identifiable  intangible
assets held for use is based on the fair value of the asset.  Long-lived  assets
and certain identifiable intangible assets to be disposed of are reported at the
lower of carrying value or 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 amounts have 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 accounts receivable,  accounts payable and other
accrued liabilities approximates fair value because of their short maturities.

The fair value of the Company's cash equivalents,  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 at December 31, 2001 and 2000
approximated   their  carrying   value.   The  fair  value  of  the  convertible
subordinated  notes at December 31, 2001 was not readily  determinable  as there
was no established public trading market for the notes.

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,  2001,  approximately  20% (2000 - 26%) 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.

                                       60


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 the products are sold by the distributors.

Advertising costs. The Company expenses all advertising costs as incurred.

Interest and other income, net. The components of interest and other income, net
are as follows:

**Consists  primarily of interest on long-term  debt  obligations  under capital
leases.

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 splits
in the form of 100% stock dividends effective February 2000 and May 1999.

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.

                                       61


Recently issued  accounting  standards.  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.  SFAS 142  requires  goodwill  to be  allocated  to,  and
assessed as part of, a reporting unit. Further, SFAS 142 specifies that goodwill
will no longer be amortized but instead will be subject to  impairment  tests at
least annually. The impairment test is a two-step process. First, the fair value
of a  reporting  unit is  compared to its  carrying  value to identify  possible
impairment and then, if necessary,  the impairment is measured  through a deemed
purchase  price  allocation.  Under  this  standard,  the  Company  will also be
required to review the useful lives of acquired  goodwill and intangible  assets
at least annually.

The Company is required to adopt SFAS 141 and 142 on a  prospective  basis as of
January 1, 2002.  The  adoption  of SFAS 141 is not  expected to have a material
effect on the Company's financial position, results of operations and cash flows
unless the Company acquires significant additional companies.

In 2002,  the Company  will no longer  amortize  goodwill  pursuant to SFAS 142,
thereby eliminating annual goodwill  amortization of approximately $2.0 million.
Goodwill  amortization  for the year ended  December 31, 2001 was $44.0 million.
Unamortized  goodwill as of December 31, 2001 was $7.1 million. The Company will
complete an initial goodwill impairment assessment in the second quarter of 2002
to determine if a transition  impairment  charge should be recognized under SFAS
142.

In October 2001, the FASB issued Statement of Financial  Accounting Standard No.
144 (SFAS  144),  "Accounting  for the  Impairment  or  Disposal  of  Long-Lived
Assets".  SFAS 144 supersedes Statement of Financial Accounting Standard No. 121
(SFAS  121),  "Accounting  for  the  Impairment  of  Long-Lived  Assets  and for
Long-Lived Assets to Be Disposed Of" and the accounting and reporting provisions
of APB  Opinion  No.  30 for  the  disposal  of a  business  segment.  SFAS  144
establishes a single  accounting  model,  based on the framework  established in
SFAS 121, for  long-lived  assets to be disposed of by sale.  The Statement also
broadens the presentation of discontinued  operations to include  disposals of a
component  of an entity and provides  additional  implementation  guidance  with
respect to the  classification of assets as held-for-sale and the calculation of
an impairment loss. The Company is required to adopt SFAS 144 effective  January
1, 2002.  The adoption of SFAS 144 is not expected to have a material  impact on
the Company's financial statements.

Reclassifications. Certain prior year amounts have been reclassified in order to
conform to the 2001 presentation.

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:

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


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.

                                       67


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 were expected to be expended 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".

                                       68


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  expects to  incorporate  this  technology,  but the  Company
expects these  products to begin  generating  revenues in the second  quarter of
2002.

Other Intangible Assets

A description of the other intangible assets acquired is set out below:

Internally  developed software acquired facilitates the completion of in process
research  and  development  projects  and can be utilized in future  development
projects.  The Company was amortizing the value assigned to internally developed
software  acquired  from  Malleable on a  straight-line  basis over an estimated
useful life of three  years.  At the  acquisition  date,  Datum had no developed
products.

The acquired assembled  workforce was comprised of skilled employees across each
of Malleable and Datum's  executive,  research and  development  and general and
administrative  groups.  The Company was  amortizing  the value  assigned to the
assembled  workforces on a straight-line  basis over their estimated useful life
of three years.

Goodwill,  which represents the excess of the purchase price of an investment in
an acquired  business  over the fair value of the  underlying  net  identifiable
assets,  was  being  amortized  on a  straight-line  basis  over  its  estimated
remaining useful life of five years.

In the second  quarter of 2001,  the  Company  discontinued  development  of the
technology  acquired in the  purchase of Malleable  and  recorded an  impairment
charge equal to the remaining net book value of the related goodwill,  developed
technology, and assembled workforce. See Note 3 "Restructuring and other costs".

Due to a decline in current  market  conditions and a delay in  introduction  of
products to the market,  the Company completed an assessment of the goodwill and
intangibles  acquired in the purchase of Datum and  recorded a total  impairment
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. See Note 3 "Restructuring and other costs".

of operations for Octera because the effect of the acquisition was not material.
This  information  may not  necessarily  be  indicative  of the future  combined
results of operations of the Company.


NOTE 3.   Restructuring and Other Costs

Restructuring - March 26, 2001

In the first quarter of 2001, PMC implemented a  restructuring  plan in response
to the decline in demand for its networking products and consequently recorded a
restructuring  charge of $19.9  million.  Prior to the end of the first quarter,
management  approved  the  restructuring  plan  committing  the  Company  to the
termination of 223 employees,  the  consolidation  of a number of facilities and
the  curtailment  of  certain  research  and  development  projects.   Employees
terminated  under this plan were advised  prior to the end of the quarter of the
termination benefits to which they were entitled.

The  elements  of the  accrued  restructuring  costs  related  to the March 2001
restructuring plan are as follows:




                                                  Total Charge     Noncash     Cash      Restructuring Liability at

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


Workforce  reduction  includes the cost of severance and related benefits of 223
employees affected by the  restructuring.  These terminations were spread across
all  business  functions,  with  approximately  70%  occurring  in Research  and
Development and the remainder occurring in Sales, Marketing,  Administrative and
Production departments.

                                       70


Facility  lease and contract  settlement  costs include:  (i) lease  termination
payments and other costs related to the closure of certain corporate facilities,
sales offices and research and development centers for activities that have been
exited  or  restructured;  and  (ii)  penalties  incurred  due to the  Company's
withdrawal from certain purchase contracts.

Certain  leasehold  improvements  located at the closed  facilities and computer
equipment and software  licenses  were  determined to be impaired as a result of
the  restructuring  activities  and were written  down to estimated  fair market
value, net of disposal costs.

PMC expects to complete the restructuring  activities  contemplated in the March
2001 plan by the end of March 2002.

Restructuring - October 18, 2001

Due to the  continued  decline in market  conditions,  PMC  implemented a second
restructuring  plan in the fourth  quarter of 2001 to reduce its operating  cost
structure.  Prior to the end of the  fourth  quarter,  management  approved  the
second  restructuring  plan  committing  the Company to the  termination  of 341
employees,   the  consolidation  of  additional  excess   facilities,   and  the
curtailment  of  additional   research  and  development   projects.   Employees
terminated  under this plan were advised  prior to the end of the quarter of the
termination  benefits  to which they were  entitled.  As a result,  the  Company
recorded a second restructuring charge of $175.3 million in its fourth quarter.

The  elements of the accrued  restructuring  costs  related to the October  2001
restructuring plan are as follows:





                                                       Total Charge         Noncash         Cash     Restructuring Liability at

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


Workforce  reduction  charges include the cost of severance and related benefits
of 341 employees  affected by the restructuring  activities.  These terminations
were spread across all business  functions,  with approximately 64% occurring in
Research and  Development  and the remainder  occurring in Sales,  Marketing and
Administrative and Production departments.

Facility lease and contract settlement costs include:  (i) lease termination and
other costs  related to the closure of corporate  facilities as a result of this
restructuring;  and (ii) penalties incurred due to the Company's withdrawal from
certain  purchase  contracts.  A significant  component of the charge for excess
facilities  relates to a Santa Clara, CA building lease committed to in 2000. To
form the plan for the  termination  of  excess  lease  facilities,  the  Company
considered  local market  conditions  for each site and estimated the timing and
amount of sublease  revenues.  The charge for  operating  and lease  termination
costs was recorded net of expected future sublease revenues.

                                       71


Certain  leasehold  improvements  located at the closed  facilities and computer
equipment,  software licenses, and related software maintenance prepayments were
written down to estimated fair market value, net of disposal costs.

PMC expects to complete the restructuring activities contemplated in the October
2001 plan by the fourth quarter of 2002.

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
does not expect to have any future cash flows related to these assets and has no
alternative  use for the  technology.  Accordingly,  the Company has 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  totaling  $20.7 million
during the year ended December 31, 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.  This 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.

                                       72

At December  31, 2001,  the Company held 2.3 million  shares (2000 - 2.4 million
shares) of Sierra  Wireless,  Inc., of which 1.2 million  shares were subject to
resale  restrictions  and could not be sold  until May  2002.  The  Company  has
classified  the  shares  as  available-for-sale  and  has  reported  the  entire
investment  at the end of 2001 at fair  value.  At the end of 2000,  1.2 million
shares were restricted beyond one year. As a result,  the investment at December
31, 2000  comprised 1.2 million  shares  recorded at cost and 1.2 million shares
that were unrestricted and recorded at fair value. The total unrealized  holding
gain related to these shares on December 31,  2001,  was $41.6  million  (2000 -
$55.2 million).

                                       73


The Company also has investments in non-public  entities,  which include venture
funds that invest in  early-stage  private  technology  companies  of  strategic
interest  to the  Company.  The  Company has  commitments  to invest  additional
capital into these funds (see Note 8). In 2001, the Company made additional cash
investments of $5.7 million (2000 - $24.8 million; 1999 - $8.5 million) in these
non-public entities.

During  the  year  ended  December  31,  2001,  the  Company  sold  some  of its
investments in public and non-public companies for cash proceeds of $3.3 million
(2000 - $59.7  million;  1999 - $28.6  million)  and  non-cash  proceeds of $1.7
million (2000 and 1999 - nil) and recorded  gross realized gains of $2.9 million
(2000 - $58.5 million; 1999 - $26.8 million). Of these amounts, cash proceeds of
$2.1 million (2000 - $59.7  million;  1999 - $28.6  million) and gross  realized
gains of $1.9 million (2000 - $58.5 million;  1999 - $26.8  million)  related to
the disposition of investments classified as available for sale.

The Company monitors the value of its investments for impairment and writes them
down to reflect any decline in value  below its cost basis,  if that  decline is
considered  to be  other  than  temporary.  In 2001,  the  Company  recorded  an
impairment  charge of $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, 2001,  the Company had available a revolving line of credit with
a bank under which the Company may borrow up to $25 million with interest at the
bank's  alternate  base rate (annual rate of 5.25% at December  31,  2001).  The
Company  cannot pay cash  dividends,  or make material  divestments  without the
prior  written  consent  of the bank.  The  agreement  expires  in May 2003.  At
December 31, 2001,  $5.3 million of the  available  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.

                                       74


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 for the years ended  December  31,  2001,  2000 and 1999 was $15.9
million, $8.3 million and $4.4 million, respectively. Excluded from rent expense
for 2001 was additional rent of $3.4 million related to excess facilities, which
have been accrued in the restructuring charges for 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 included in the table below.

Minimum future rental payments under these leases are as follows:

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  $40.7 million into these funds,  which may be
requested by the fund managers at any time over the next eight 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, 2001 and 2000, the Company maintained a reserve of 3,373,000 and
3,746,000  shares,  respectively,  of  PMC-Sierra  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,  1998,  the Company had an
authorized capital of 105,000,000  shares,  100,000,000 of which were designated
"Common  Stock",  $0.001  par value,  and  5,000,000  of which  were  designated
"Preferred Stock", $0.001 par value.

During 2000 and 1999 the  Company's  stockholders  elected to add an  additional
700,000,000 and 100,000,000 authorized shares of common stock, respectively,  to
the  100,000,000  shares  of common  stock  authorized  at the end of 1998.  The
Company currently has 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 April  1999,  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 April 30, 1999, and effective
on May 14, 1999.

                                       76


In January 2000, the Company's Board of Directors  approved another  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 these stock dividends.

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.  These warrants  expire between October 2002 and December 2005. In
2001,  50,759 of these warrants were  cancelled.  At December 31, 2001, 2000 and
1999,  there were 42,138  warrants  outstanding at a weighted  average  exercise
price of $1.66, 92,897 warrants outstanding at a weighted average exercise price
of $5.87  per share and  366,633  warrants  outstanding  at a  weighted  average
exercise price of $3.87 per share, respectively.

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.  At  December  31,  1999,  QED  had a  total  of
13,619,000  preferred  shares  outstanding.  Proceeds  of  these  shares  net of
issuance  costs were  approximately  $39.9  million.  On February  1, 2000,  QED
completed its initial public offering of common stock.  Simultaneously  with the
closing of the initial public  offering,  all issued and  outstanding  shares of
QED's convertible  preferred stock 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, 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, 2001 and 2000,
these  shares  were   exchangeable   into  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 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.
During 1998, the Company's  stockholders elected to add a provision to the ESPP.
Under the new  terms,  the  number  of shares  authorized  to be  available  for
issuance under the plan shall be increased automatically on January 1, 1999, and
every year  thereafter  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 have been reserved for issuance under this Plan. Under this Plan, eligible
employees  may 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 2001,  2000, and 1999,  there were 245,946 shares,  235,104  shares,  and
229,518 shares, respectively,  issued under the Plans at weighted-average prices
of $31.93, $16.21, and $8.12 per share, respectively.  The weighted-average fair
value of the 2001,  2000,  and 1999  awards was  $31.25,  $41.90,  and $9.32 per
share,  respectively.   During  2001,  an  additional  1,622,201  shares  became
available  under the PMC ESPP and no additional  shares were  authorized for the
QED ESPP. As of December 31, 2001,  4,846,149  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 the  expiration of the plan.  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 addition, the Company assumed the stock option plans of each of the companies
it acquired prior to 2001 (see Note 2). In 2001, the company simplified its plan
structure by merging these plans into one plan. All option  activity  related to
these plans is included in the following tables.

Option activity under the option plans was as follows:

Stock-based  compensation.  In  accordance  with the  provisions of Statement of
Financial   Accounting   Standards   No.  123,   "Accounting   for   Stock-Based
Compensation"  (SFAS  123),  the  Company  applies  APB  Opinion 25 and  related
interpretations in accounting for its stock-based  awards. The Company's ESPP is
non-compensatory under Accounting Principles Board (APB) Opinion 25. The Company
also does not recognize compensation expense for employee stock options that are
granted with  exercise  prices  equal to the fair market value of the  Company's
common stock at the date of grant.

                                       79


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:



                                      Options                              ESPP

Expected life (years)                   3.0       3.1        3.4            0.9        1.4        1.4

The  weighted-average  estimated fair values of employee  stock options  granted
during  fiscal 2001,  2000,  and 1999 were $10.98,  $74.32 and $14.27 per share,
respectively.

If the computed fair values of 2001, 2000, and 1999 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:

Net income (loss)                                  $(747,445)       $18,682       $51,238

Diluted net income (loss) per share                $   (4.45)       $  0.10       $  0.32


Because SFAS 123 is applicable only to awards granted or modified  subsequent to
December 31, 1994,  the pro forma effect is not  indicative  of future pro forma
adjustments, when the calculation will apply to all applicable stock awards.

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

At December 31, 2001,  the Company has  approximately  $491.7 million of federal
net  operating  losses,  which will expire  through  2021.  Approximately  $10.3
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  $182.1  million  of state tax loss  carryforwards,  which  expire
through 2021. 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  carryfowards  are $14.5 million of federal  research and
development  credits which expire through 2021,  $549,000 of foreign tax credits
which  expire in 2003,  $410,000  of  federal  AMT  credits  which  carryforward
indefinitely,  $8.4 million of state research and  development  credits which do
not expire,  $1.2 million of state research and development credits which expire
through 2006, and $1.1 million of state manufacturer's  investment credits which
expire through 2010.

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
$144.8 million of cumulative tax benefits related to equity transactions,  which
will be credited to stockholder's equity if and when realized.

                                       82


The pretax income (loss) from foreign  operations was ($154.1  million),  $254.5
million, and $119.3 million in 2001, 2000, and 1999, 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
includes   custom  user  interface   products.   The  Company  is  supporting  a
non-networking  product for an existing customer, 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:
