INDUSTRY OVERVIEW

Growth in Internet usage and digital consumer devices continues to drive demand for bandwidth and efficient networks that can manage high levels of data
and video traffic. At the same time, communication service providers are seeking ways to increase their revenues by bundling and delivering a range of services to their customers in a cost-effective manner. Applications such as Voice Over
Internet Protocol (VoIP), video-on-demand, and Internet Protocol Television (IPTV) are enabled by advanced technology such as third generation wireless services, network-attached storage, Fibre-To-The-Home access, and Metro
Optical Transport networks. This results in increasing requirements for carriers and enterprises to upgrade and improve their network infrastructure and storage management capabilities. Enterprises, governments, corporations, small offices and
home offices are expanding their networks to better capture, store and access large quantities of data, efficiently and securely.

MARKETS THAT WE SERVE

We sell our semiconductor
solutions primarily into three general markets: Enterprise Networking; Wide Area Network Infrastructure; and Access Networks. The products and solutions that we sell into the Access and Wide Area Network markets are largely driven by the
capital spending of service providers in the communications equipment industry. Our products and solutions that are sold into the Enterprise Networking market are driven primarily by the capital spending of corporations, enterprises, and smaller
businesses. In 2008, our revenues were derived approximately 50% from the Access and Wide Area Network markets, and 50% from the Enterprise Networking market.

The general market areas that we currently serve and some typical equipment in those markets that contain our semiconductor solutions are described below. Due to the complexity of the global communications
network, it is not possible to sharply delineate networking functions or markets served. In addition, many of our products may be used in multiple classes of networking equipment that are deployed across all of the market areas identified
below, while some of our products have highly specialized applications. For example, our microprocessors can be used in

##### Table of Contents

many networking equipment applications (such as color laser printers or high-speed routers), while a single wireless infrastructure chip may only be used in
one specific application (e.g., pre-distortion of power amplification for a wireless base station). In some situations, different original equipment manufacturers (OEMs) might use solutions in equipment addressing more than
one of the market areas noted below.

Access Networks

The Access area of the communications network encompasses both wired and wireless equipment that aggregates data traffic from enterprises and homes and transmits it to the central offices in the metropolitan area of the network. Our
solutions are used in Access equipment such as aggregation and multi-service provisioning platforms, switches, and routers. One key industry protocol that helps in packaging information into formats for transportation across various
networks is Internet Protocol (IP). As networks slowly converge over time, more data-centric and hybrid multi-service equipment is required to handle voice, video, and data services over the IP. The Access area of the network
also involves the termination and distribution of separate higher speed data signals into lower speed data signals. Many of our devices that are used in wireline communications equipment can also be deployed in the transmission of wireless data from
base station transceivers and base station controllers.

In Asia and some parts of North America, Passive Optical Networking
(PON) is being deployed by carriers to facilitate higher speed access service. Instead of copper cables, fibre is deployed to the neighborhood, the multi-dwelling unit, or the residence, to increase bandwidth and improve the
uploading and downloading files in both directions. The advantage of PON is that it provides high bandwidth without sensitivity to the distance between the central office and the subscriber. This technology is being widely deployed in Japan,
and in China it is in the early stages as carriers in that market transition from field trials to broader commercial deployment.

Wide Area Network

The Wide Area Network portion of the communications network is primarily a fibre optic-based system that provides high-speed communications
and data transfer within a city center, a metropolitan area, or a wider regional area. This portion of the network manages traffic inside its own region, and also manages traffic between the Access and Long-haul transport networks for
inter-city or international transmission.

For high-capacity data communication over fibre optic systems, the standard used is Synchronous
Optical Networks (SONET) in North America and parts of Asia, and is Synchronous Digital Hierarchy (SDH) in the rest of the world. In addition to using SONET/SDH to increase the bandwidth, or capacity, of their networks,
many service providers are also deploying packet-based transport equipment that uses wave division multiplexing (WDM). Rather than transmitting a single light signal over an optical fibre, wave division multiplexing allows many
different light signals (each of a different wavelength) to be transmitted simultaneously. By deploying this technique at higher transmission rates, carriers can move more signals across transmission lines.

Our products and solutions are used in networking equipment such as multi-service switches and edge routers that gather and process signals in different
protocols, and then transmit them to the next destination as quickly and efficiently as possible. The next-generation equipment in networking that can efficiently handle different data protocols is often referred to as multi-service
provisioning platforms that facilitate the transmission of IP packets over optical fibre. We are developing complex architectural silicon solutions to help our customers manage the increasing level of diverse traffic in the Wide Area Network.

Enterprise Networking

Our products and
solutions in the Enterprise Networking market enable the high-speed interconnection of the servers, switches and storage devices that comprise these systems so that large quantities of data can be stored, managed and moved securely. Our focus in
this area is developing interconnect devices and controllers

##### Table of Contents

for Fibre Channel, Serial Attached SCSI (SAS) and Serial ATA (SATA). We are also shipping next-generation solutions such as 8 Gbps
Fibre Channel controllers for high-performance storage systems in the Storage Area Network (SAN) and Network Attached Storage (NAS) markets. We have also introduced 6 Gbps SAS/SATA controllers and expanders for the external
storage market, as well as a 6 Gbps RAID-on-Chip (ROC) controller for the server-attached storage market.

We also provide
integrated solutions for laser printers, switches, and routers that are used by enterprises and small businesses to manage their data on an inter-office and intra-office basis. In the laser printer market, we sell our standalone microprocessors and
integrated system-on-chip devices primarily into the mid- to high-end and multi-function segments of that market. We also have applications for networked-attached storage for small and medium sized businesses.

OUR PRODUCTS

Most of our semiconductors can be divided into broadly defined functional categories as 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 may integrate several different functions and therefore could be classified in one or more categories. For example, some of our products convert high-speed analog signals (wired or wirelessly) to
digital signals and split or combine various transmission signals.

Controllers: rapid growth in data storage is driving a requirement
for more cost-effective and larger capacity storage systems. Controller products based on Fibre Channel, SAS, and SATA enable the development of external and server-attached storage systems that meet the cost and capacity requirements of our
customers.

Framers and mappers: before 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/SDH frames, for transmission across high-speed fibre optic networks.

Line interface units: these devices, also referred to as transceivers, transmit and receive signals over a physical medium such as wire, cable or
fibre. 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.

Microprocessor-based System-On-Chips (SOCs): these devices perform the high-speed computations that help identify
and control the flow of signals and data in many different types of networking equipment used in the communications, enterprise and consumer markets. With greater demand for integration of features and functions on a single device, more
system-on-chip solutions are being developed.

Packet and cell processors: these devices examine the contents of cells, or packets,
and perform various management and reporting functions. For instance, a switch or router may use a packet or cell processor to determine if a signal is voice or video in order to allocate the proper amount of bandwidth for
transmission.

Radio Frequency (RF) transceivers: the rapid growth of mobile and nomadic data services is accelerating the need
for higher bandwidth RF transceivers (a.k.a. radios). These radios transmit and receive broadband signals over the air using Orthogonal Frequency-Division Multiple Access (OFDMA) based protocols and Multiple-Input-Multiple-Output
(MIMO) antenna technology.

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

planning process, we are in regular contact with our key customers to discuss industry trends, emerging standards and ways in which we can assist in their new product requirements.

Our sales team is focused on selling and supporting our chips and chipsets for equipment providers who are in turn selling their products to service
providers, enterprises, or consumers. To better match our available sales resources to market opportunities we also focus our sales and support efforts on targeted customers.

We sell our products to end customers directly and through distributors and independent manufacturers representatives. In 2008, less than 30% of
our orders were shipped through distributors, approximately 41% were sent by us directly to contract manufacturers selected by OEMs, and the balance were sent directly to our OEM customers.

In 2008, our largest distributor was Avnet Inc., which represented our products worldwide (excluding Japan, Israel, and Taiwan). We recognize sales
through Avnet on a sell-through basis, which occurs when Avnet ships our products to the end customer. In 2008, total sales shipped through Avnet worldwide were 14% of our total revenues. Our second largest distributor is Macnica Inc. Sales shipped
through this distributor in 2008 were approximately 14% of our total revenues.

Our sales outside of the United States, based on customer
billing location, accounted for 80%, 80% and 76% of total revenue in 2008, 2007, and 2006, respectively. Our sales to customers in Asia, including Japan and China, increased to 73% of sales in 2008 from 65% of sales in 2007 in part because many of
our OEM customers increased the use of Asia-based contract manufacturers for the assembly of their products.

MANUFACTURING

PMC-Sierra is a fabless company, meaning that we do not own or operate
foundries for the production of the silicon wafers from which our products are made. Instead, we work with independent merchant foundries and chip assemblers for the manufacture of our products. We believe our fabless approach to manufacturing
provides us with the benefit of superior manufacturing capability, scalability, as well as the flexibility to move wafer manufacture, assembly and test of our products to the vendors that offer the best technology and service, at a competitive
price.

Our lead-time, or the time required to manufacture our devices, is typically 10 to 14 weeks. Based on this lead-time, our team of
production planners initiates purchase orders with our wafer suppliers and with our chip assemblers for the assembly and test of our parts so that, to the best of our ability, our products are available to meet customer demand.

Wafer Fabrication

We manufacture our products at
independent foundries using standard Complementary Metal Oxide Semiconductor (CMOS) process techniques. We have in the past purchased silicon wafers from which we manufacture our products from Chartered Semiconductor Manufacturing Ltd.
(Chartered), Taiwan Semiconductor Manufacturing Corporation (TSMC) and United Microelectronics Corporation (UMC).

##### Table of Contents

These independent foundries produce the wafers for our networking semiconductor products ranging in sizes from 0.18 micron to 65 nanometer. By using
independent foundries to fabricate our wafers, we are better able to concentrate our resources on designing, developing and testing of new products. In addition, we avoid the fixed costs associated with owning and operating fabrication and chip
assembly facilities and the costs associated with updating these facilities to manage constantly evolving process technologies.

We have
supply agreements with Chartered, TSMC and UMC. Under these supply agreements, the foundries must supply certain quantities of wafers per year. Neither of these agreements have minimum unit volume requirements. These agreements may be terminated if
either party does not comply with the terms. We have a history of renewing contracts on an annual basis with our foundries, for those agreements that require renewals, and we do not anticipate any problems with renewing such agreements beyond their
expiry dates.

Assembly and Test

Once our
wafers are fabricated, they must be probed, or inspected, to identify which individual units, referred to as die, were properly manufactured. Most wafers that we purchase are sent directly to an outside assembly house where the die are individually
cut and packaged into semiconductor devices. The individual devices are then run through various electrical, mechanical and visual tests before customer delivery. PMC has recently outsourced the remaining in-house portion of its wafer probe and
final test capability to subcontract test providers.

Quality Assurance

The industries that we serve require high quality, reliable semiconductors for incorporation into their equipment. We pre-qualify each vendor, foundry, assembly and test subcontractor. Wafers supplied by outside
foundries must meet our incoming quality and test standards. The testing function is performed predominantly by independent Asian and U.S. companies.

Since 2006, there has been an increase in the proportion of products being produced for PMC by turnkey application-specific integrated circuit (ASIC) vendors, due to PMCs acquisitions of the
Storage Semiconductor Business and Passave. Although PMC does not physically manage the bulk of this production, these products follow approved and audited flows conforming to PMCs Quality Assurance requirements.

RESEARCH AND DEVELOPMENT

Our research and development efforts are market and customer-focused and can involve the development of both hardware and software. These devices and reference designs are targeted for use in enterprise, storage and
service provider markets. Increasingly, our OEM customers that serve these end markets are demanding complete solutions with software support and complex feature sets and we are developing products to fill this need.

From time to time we announce new products to the public once development of the product is substantially completed, and there are no longer significant
technical risks and costs to be incurred. As we have a portfolio of approximately 350 products, we do not consider any individual new product or group of products released in a year to be material, beyond our continuing development of a portfolio of
products that meet our customers future needs.

##### Table of Contents

At the end of fiscal 2008, we had design centers in the United States (California, Oregon, Pennsylvania
and Minnesota), Canada (British Columbia and Quebec), Israel (Herzliya), China (Shanghai) and India (Bangalore).

Our research and
development spending was $157.6 million in 2008, $159.1 million in 2007, and $158.7 million in 2006. These figures exclude in-process research and development acquired in business combinations.

BACKLOG

Our
sales originate from customer purchase orders. However, our customers frequently revise order quantities and shipment schedules to reflect changes in their requirements. As of December 28, 2008, our backlog of products scheduled for shipment
within three months totaled approximately $68.0 million (2007$95.5 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 2009.

Our backlog includes our backlog of shipments to direct customers, minor distributors and a portion of shipments by our major distributor to end
customers. Our customers may cancel or defer backlog orders. Accordingly, we believe that our backlog at any given time is not a meaningful indicator of future long-term revenues. Backlog is a non-GAAP measure.

COMPETITION

We
typically face competition at the customer design stage when our customers are determining which semiconductor components to use in their equipment designs.

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



| |  |  | meets the functional requirements;
| | - |  | ----------------------------------



| |  |  | interfaces easily with other components in the product;
| | - |  | -------------------------------------------------------



| |  |  | meets power usage requirements;
| | - |  | -------------------------------



| |  |  | is priced competitively; and
| | - |  | ----------------------------



| |  |  | is commercially available on a timely basis.
| | - |  | --------------------------------------------

OEMs are becoming more price conscious as semiconductors sourced from third party suppliers start to comprise a larger portion of the total materials cost in OEM equipment. This price sensitivity from our customers can lead to aggressive
price competition by competing suppliers that may force us to decrease our prices to win a design and therefore decrease our gross profit.

OEMs 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 semiconductor
component design. OEMs also consider whether a supplier has been pre-qualified, as this ensures that components made by that supplier will meet the OEMs quality standards.

We compete against established peer-group semiconductor companies that focus on the communications and storage semiconductor business. These companies
include Applied Micro Circuits, Broadcom, Cortina, Emulex, Exar, Infineon, Intel, LSI, Marvell, Maxim, Mindspeed, QLogic, Texas Instrument and Vitesse. Many of these companies are well financed, have significant communications semiconductor
technology assets and established sales channels, and depend on the market in which we participate for the bulk of their revenues.

##### Table of Contents

Over the next few years, it is possible for additional competitors to enter the market with new products,
some of which may also have greater financial and other resources than us.

We are also continuing to expand into certain markets, such as
the Enterprise Networking market that have established incumbents with substantial financial and other resources. Some of these incumbents derive a majority of their earnings from these markets. We expect continued strong competition in these
markets.

LICENSES, PATENTS AND TRADEMARKS

We rely in part on patents to protect our intellectual property and have a total of 269 U.S. and 86 foreign patents for circuit designs and other
innovations used in the design and architecture of our products. In addition, we have 98 patent applications pending in the U.S. Patent and Trademark office. Our patents typically expire 20 years from the patent application date, with our existing
patents expiring between 2009 and 2028.

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

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

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

EMPLOYEES

As of December 28, 2008, we had 1,064 employees, including 632 in Research and Development, 86 in Production and Quality Assurance, 214 in Sales and
Marketing and 132 in Administration. Our employees are not represented by a collective bargaining agreement and we have never experienced any related work stoppage.



|ITEM 1A. | Risk Factors.
|-------- | -------------

Our company is subject to a number
of riskssome are normal to the fabless 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 the following risks, our business, financial condition, operating results and/or liquidity 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.

Our global growth is subject to a number of economic risks.

As widely reported, financial markets in the United States, Europe and Asia have been experiencing extreme disruption in recent months, including among
other things, extreme volatility in security prices, severely diminished liquidity and credit availability, rating downgrades of certain investments and declining valuations of others. Governments have taken unprecedented actions intended to address
extreme market conditions that include severely restricted credit and declines in real estate values. We have experienced delays in redemptions of our money market funds and we have recognized an $11.8 million loss on investment securities on our
shares

of the Reserve International Liquidity Fund, Ltd. (the International Fund) and the Reserve Primary Fund (the Primary Fund, together
the Reserve Funds) during 2008. Changes in market conditions and the method and timing of the liquidation process of the Reserve Funds could result in further adjustments to the fair value and classification of these investments, and
these changes could be material.

Currently these conditions have not impaired our liquidity for operational purposes. There can be no
assurance that there will not be a further deterioration in financial markets and confidence in major economies, which may impair our liquidity in the future. The current tightening of credit in financial markets adversely affects the ability of
customers and suppliers to obtain financing for significant purchases and operations and could result in a decrease in or cancellation of orders for our products and services. Our global business is also adversely affected by decreases in the
general level of economic activity, such as decreases in business and consumer spending, financial strength of our customers and suppliers. We are unable to predict the likely duration and severity of the current disruption in financial markets and
adverse economic conditions in the U.S. and other countries.

Finally, our ability to access the capital markets may be severely restricted
at a time when we would like, or need to do so, which could have an impact on our flexibility to pursue additional expansion opportunities and maintain our desired level of revenue growth in the future.

We are subject to rapid changes in demand for our products due to:



| |  |  | variations in our turns business;
| | - |  | ---------------------------------



| |  |  | short order lead time;
| | - |  | ----------------------



| |  |  | customer inventory levels;
| | - |  | --------------------------



| |  |  | production schedules; and
| | - |  | -------------------------



| |  |  | fluctuations in demand.
| | - |  | -----------------------

As a result
of this uncertainty in the demand for our products, our past operating results may not be indicative of our future operating results.

Our revenues and
profits may fluctuate because of factors that are beyond our control. As a result, we may fail to meet the expectations of security analysts and investors, which could cause our stock price to decline.

Our ability to project revenues is limited because a significant portion of our quarterly revenues may be derived from orders placed and shipped in the
same quarter, which we call our turns business. Our turns business varies widely from quarter to quarter. Our customers may delay product orders and reduce delivery lead-time expectations, which may reduce our ability to project revenues
beyond the current quarter. While we regularly evaluate end users and contract manufacturers inventory levels of our products to assess the impact of their inventories on our projected turns business, we do not have complete information
on their inventories. This could cause our projections of a quarters turns business to be inaccurate, leading to lower revenues than projected.

We may fail to meet our forecasts if our customers cancel or delay the purchase of our products or if we are unable to meet their demand.

We rely on customer forecasts in order to estimate the appropriate levels of inventory to build and to project our future revenues. Many of our customers have numerous product lines, numerous component requirements
for each product, sizeable and complex supplier structures, and typically engage contract manufacturers for additional manufacturing capacity. This complex supply chain creates several variables that make it complicated



12

##### Table of Contents

to accurately forecast our customers demand and accurately monitor their inventory levels of our products. If customer forecasts are not accurate, we
may build too much inventory, potentially leaving us with excess and obsolete inventory, which would reduce our profit margins and adversely affect our operating results. Conversely, we may build too little inventory to meet customer demand causing
us to miss revenue-generating opportunities. The cancellation or deferral of product orders, the return of previously sold products or overproduction due to the failure of anticipated orders to materialize could result in our holding excess or
obsolete inventory, which could result in write-downs of inventory. This difficulty may be compounded when we sell to OEMs indirectly through distributors and other resellers or contract manufacturers, or both, as our forecasts of demand are then
based on estimates provided by multiple parties.

Our customers often shift buying patterns as they manage inventory levels, market
different products, or change production schedules. This makes forecasting their production requirements difficult and can lead to an inventory surplus or shortage of certain of their components. In addition, our products vary in terms of profit
margins they generate. If our customers purchase a greater proportion of our lower margin parts in a particular period, it would adversely impact our results of operations.

Further, our distributors provide us with periodic reports of their backlog to end customers, sales to end customers and quantities of our products that
they have on hand. If the data that is provided to us is inaccurate, it could lead to inaccurate forecasting of our revenues or errors in our reported revenues, gross profit and net income.

While backlog is our best estimate of our next quarters revenues, it is industry practice to allow customers to cancel, change or defer orders with
limited advance notice prior to shipment. As such, backlog may be an unreliable indicator of future revenue levels. Because a significant portion of our operating expenses are fixed, even a small revenue shortfall can have a disproportionately
negative effect on our operating results.

If the demand for our customers products declines, demand for our products will be similarly affected
and our revenues, gross margins and operating performance will be adversely affected.

Our customers are subject to their own business
cycles, most of which are unpredictable in commencement, depth and duration. We cannot accurately predict the continued demand of our customers products and the demands of our customers for our products. In the past, networking customers have
reduced capital spending without notice, adversely affecting our revenues. As a result of this uncertainty, our past operating results may not be indicative of our future operating results. It is possible that, in future periods, our results may be
below the expectations of public market analysts and investors. This could cause the market price of our common stock to decline.

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. The loss of a key customer could materially impact our results of operations.

We depend on a limited number of customers for large portions of our revenues. In 2008, we did not have any end customers that accounted for more than 10%
of our revenues, although we did in the past. In 2007, through direct, distributor and subcontractor purchases, Cisco Systems and EMC Corporation each accounted for more than 10% of our revenues. We do not have long-term volume purchase commitments
from any of our major customers. We sell our products solely on the basis of purchase orders. Those customers could decide to cease purchasing products with little or no notice and without significant penalties. A number of factors could cause our
customers to cancel or defer orders, including interruptions to their operations due to a downturn in their industries, delays in manufacturing their own product offerings into which our products are incorporated, and natural disasters. 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.

##### Table of Contents

The loss of a key customer, or a reduction in our sales to any major customer or our inability to attract
new significant customers could materially and adversely affect our business, financial condition or results of operations.

The loss of key personnel
could delay 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. The competition for such employees is intense.

We do not have employment
agreements in place with many of our key personnel. As employee incentives, we issue common stock options and restricted stock grants that are subject to time vesting, and, in the case of options, have exercise prices at the market value on the
grant date. As our stock price varies substantially, the equity awards to employees are effective as retention incentives only if they have economic value.

Changes in the political and economic climate in the countries we do business may adversely affect our operating results.

We earn a substantial portion of our revenues in Asia. We conduct an increasing portion of our research and development and manufacturing activities outside North America. We procure substantially all of our wafers from Taiwan and use
assemblers and testers throughout Asia.

Given the depth of our sales and operations in Asia, we face risks that could negatively impact
our results of operations, including economic sanctions imposed by the U.S. government, imposition of tariffs and other potential trade barriers or regulations, uncertain protection for intellectual property rights and generally longer receivable
collection periods. In addition, fluctuations in foreign currency exchange rates could adversely affect the revenues, net income, earnings per share and cash flow of our operations in affected markets. Similarly, fluctuations in exchange rates
may affect demand for our products in foreign markets or our cost competitiveness and may adversely affect our profitability.

Our results
of operations are increasingly dependent on our sales in China, which accounted for 30% of our revenues in 2008. Government agencies in China have broad discretion and authority over all aspects of the telecommunications and information technology
industry in China; accordingly their decisions may impact our ability to do business in China. Therefore, significant changes in Chinas political and economic conditions and governmental policies could have a substantial impact on our
business. The growth of Fibre-To-The-Home technology in China has continued to be strong, however, a slowdown in that growth would have an adverse impact on our operating results.

In addition to selling our products in a number of countries, an increasing portion of our research and development and manufacturing is conducted
outside North America, in particular, India and China. The geographic diversity of our business operations could hinder our ability to coordinate design, manufacturing 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.

Hostilities in the Middle
East and India may have a significant impact on our Israeli and India subsidiaries ability to conduct its business.

We have
research and development facilities located in Israel and India which employ approximately 170 and 69 people, respectively. A catastrophic event, such as a terrorist attack that results in the destruction or disruption of any of our critical
business or information technology systems in Israel or India could harm our ability to conduct normal business operations and our operating results.

##### Table of Contents

On an on-going basis, some of our Israeli employees are periodically called into active military duty. In
the event of severe hostilities breaking out, a significant number of our Israeli employees may be called into active military duty, resulting in delays in various aspects of production, including product development schedules.

Our revenues may decline if we do not maintain a competitive portfolio of products.

We are experiencing significantly greater competition in the markets in which we participate. We are expanding into markets, such as the Enterprise Networking and Access Networks markets, which may have established
incumbents with substantial financial and technological resources. We expect more intense competition than that which we have traditionally faced as some of these incumbents derive a majority of their earnings from these markets.

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

Our customers are increasingly price conscious, as semiconductors sourced from third party suppliers comprise a greater portion of the
total materials cost in networking equipment. We continue to experience 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.

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

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

From time to time, we announce new products and design wins for existing and new products. While some industry analysts may use design wins as a metric for future revenues, many design wins have not, and will not, generate any revenues for
us, as customer projects are cancelled or unsuccessful in their end market. In the event a design win generates revenues, the amount of revenues 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 more than two years to generate meaningful revenues.

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

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

##### Table of Contents

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 12 and 24 months from initial conceptualization to development of a viable prototype, and another three to 18 months to be designed into our customers equipment and sold in production quantities. We sell products whose characteristics
include evolving industry standards, short product life spans and new manufacturing and design technologies. 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. Redesigning our products is expensive and may delay
production of our products. Our products may become obsolete during these delays, resulting in our inability to recoup our initial investments in product development.

The final determination of our income tax liability may be materially different from our income tax provision.

We are subject to income taxes in both the United States and international jurisdictions. Significant judgment is required in determining our worldwide provision for income taxes. In the ordinary course of our business, there are
many transactions where the ultimate tax determination is uncertain. Additionally our calculations of income taxes are based on our interpretations of applicable tax laws in the jurisdictions in which we file. Although we believe our tax
estimates are reasonable, there is no assurance that the final determination of our income tax liability will not be materially different than what is reflected in our income tax provisions and accruals. Should additional taxes be assessed as a
result of new legislation, an audit or litigation, if our effective tax rate should change as a result of changes in federal, international or state and local tax laws, or if we were to change the locations where we operate, there could be a
material effect on our income tax provision and results of operations in the period or periods in which that determination is made, and potentially to future periods as well. During the second quarter of 2008, one of our foreign subsidiaries settled
several ongoing tax matters for less than had been accrued as part of its liability for unrecognized tax benefits, resulting in the recognition of tax benefits of $124.1 million. As a result of this settlement, the Company agreed to pay $18.0
million in cash and utilize $31.6 million in investment tax credits.

We have applied the guidance in the FASB issued interpretation
No. 48, Accounting for Uncertainty in Income TaxesAn Interpretation of FASB Statement No. 109, (FIN 48) in determining our accrued liability for unrecognized tax benefits, which totaled $26.8 million on a
world-wide consolidated basis as at December 28, 2008. The ultimate resolution of outstanding tax matters could be for amounts in excess of our reserves established in accordance with FIN 48. Such events could have a material adverse effect on
our liquidity or cash flows in the quarter in which an adjustment is recorded or the tax payment is due.

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, and selling and administrative costs are incurred in foreign currencies. The U.S. dollar has fluctuated significantly compared to other foreign currencies and this trend may continue. To protect against reductions in value and the
volatility of future cash flows caused by changes in foreign exchange rates, we enter into foreign currency forward contracts. The contracts reduce, but do not eliminate, the impact of foreign currency exchange rate movements. In addition, this
foreign currency risk management policy may not be effective in addressing long-term fluctuations since our contracts do not extend beyond a 12-month maturity.

We regularly limit our exposure to foreign exchange rate fluctuations from our foreign net asset or liability positions. We recorded a net $8.2 million foreign exchange gain on the revaluation of our income tax
liability, net of deferred tax assets, in 2008 because of the fluctuations in the U.S. dollar against foreign currencies. A 5% shift in the foreign exchange rates between U.S. dollar and the Canadian dollar would cause an approximately $1.2 million
impact to our pre-tax net income.

##### Table of Contents

We are exposed to the credit risk of some of our customers.

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 OEM customers, who do not guarantee our credit receivables related to their contract manufacturers.

In
addition, a significant portion of our sales flows through our distribution channel, which generally represents a higher credit risk. Should these companies encounter financial difficulties, our revenues could decrease, and collection of our
significant accounts receivables with these companies or other customers could be jeopardized.

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

Acquiring products,
intellectual property, technologies, and businesses from third parties is a core part of our business strategy. That strategy depends on the availability of suitable acquisition candidates at reasonable prices and our ability to resolve challenges
associated with integrating acquired businesses into our existing business. These challenges include integration of product lines, sales forces, customer lists and manufacturing facilities, development of expertise outside our existing business,
diversion of management time and resources, possible divestitures, inventory write-offs and other charges. We also may be forced to replace key personnel who may leave our Company as a result of an acquisition. We cannot be certain that we will find
suitable acquisition candidates or that we will be able to meet these challenges successfully. Acquisitions could also result in customer dissatisfaction, performance problems with the acquired company, investment, or technology, the assumption of
contingent liabilities, or other unanticipated events or circumstances, any of which could harm our business. Consequently, we might not be successful in integrating any acquired businesses, products or technologies and may not achieve anticipated
revenues and cost benefits.

An acquisition could absorb substantial cash resources, require us to incur or assume debt obligations, or
issue additional equity. If we are not able to obtain financing, then we may not be in a position to consummate acquisitions. If we issue equity securities in connection with an acquisition, we may dilute our common stock with securities that have
an equal or a senior interest in our Company.

From time to time, we license, or acquire, technology from third parties to incorporate into
our products. Incorporating technology into our products may be more costly or more difficult than expected, or require additional management attention to achieve the desired functionality. The complexity of our products could result in unforeseen
or undetected defects or bugs, which could adversely affect the market acceptance of new products and damage our reputation with current or prospective customers.

Our current product road map will, in part, be dependent on successful acquisition and integration of intellectual property cores developed by third parties. If we experience difficulties in obtaining or integrating
intellectual property from these third parties, it could delay or prevent the development of our products in the future.

Although our
customers, our suppliers, and we rigorously test our products, our highly complex products may contain defects or bugs. We have in the past experienced, and may in the future experience defects and bugs in our products. 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



17

##### Table of Contents

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.

Our business may be adversely affected if our customers or suppliers cannot obtain sufficient supplies of other components needed in their product offerings to meet
their production projections and target quantities.

Some of our products are used by customers in conjunction with a number of other
components, such as transceivers, microcontrollers and digital signal processors. If, for any reason, our customers experience a shortage of any component, their ability to produce the forecasted quantity of their product offerings may be affected
adversely and our product sales would decline until the shortage is remedied. Such a situation could harm our operating results, cash flow and financial condition.

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. Two outside wafer foundries supply more than 95% of our semiconductor wafer requirements. Our wafer foundry suppliers also make products for other companies and some make products for themselves, thus 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 wafer foundries we use are unable
or unwilling to manufacture our products in required volumes, or at specified times, 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, at an acceptable cost, 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 for assembly and testing of our semiconductor products that could delay and limit our product shipments.

We depend on third parties in Asia for the assembly and testing of our semiconductor products. In addition, subcontractors in Asia assemble
all of our semiconductor products into a variety of packages. Raw material shortages, political and social instability, assembly and testing house service disruptions, currency fluctuations, or other circumstances in the region could force us to
seek additional or alternative sources of supply, assembly or testing. This could lead to supply constraints or product delivery delays that, in turn, may result in the loss of revenues. At times, capacity in the assembly industry has become scarce
and lead times have lengthened. This may become more severe, which could in turn adversely affect our revenues. We have less control over delivery schedules, assembly processes, testing processes, quality assurances, raw material supplies, and costs
than competitors that do not outsource these tasks.

Due to the amount of time that it usually takes us to qualify assemblers and testers,
we could experience significant delays in product shipments if we are required to find alternative assemblers or testers for our components. Any problems that we may encounter with the delivery, quality or cost of our products could damage our
customer relationships and materially and adversely affect our results of operations. We are continuing to develop relationships with additional third-party subcontractors to assemble and test our products. However, even if we use these
new subcontractors, we will continue to be subject to all of the risks described above.

Our business is vulnerable to interruption by earthquake, fire, power loss, telecommunications failure, terrorist
activity and other events beyond our control.

We do not have sufficient business interruption insurance to compensate us for actual
losses from interruption of our business that may occur, and any losses or damages incurred by us could have a material adverse effect on our business. We are vulnerable to a major earthquake and other calamities. We have operations in seismically
active regions in British Columbia, Canada and California, and we rely on third-party wafer fabrication and testing facilities in seismically active regions in Asia. We have not undertaken a systematic analysis of the potential consequences to our
business and financial results from a major earthquake in either region. We are unable to predict the effects of any such event, but the effects could be seriously harmful to our business.

Our estimated restructuring accruals may not be adequate.

In 2005, 2006 and 2007, we implemented restructuring plans to streamline production and reduce and reallocate operating costs. In 2001 and 2003, we implemented plans to restructure our operations in response to the decline in demand for our
networking products. We reduced the workforce and consolidated or shut down excess facilities in an effort to bring our expenses into line with our revenue expectations.

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

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 or misappropriating our technology and selling similar products, which would harm our revenues.

To compete effectively, we must protect our intellectual property. 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 numerous patents and have a number of pending patent applications. However some of our patents are expiring in 2009, which could have a
negative affect on our ability to prevent competitors from duplicating certain of our products.

We might not succeed in obtaining 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.

To protect our product technology,
documentation and other proprietary information, we enter into confidentiality agreements with our employees, customers, consultants and strategic partners. We require our employees to acknowledge their obligation to maintain confidentiality with
respect to PMCs products. Despite these efforts, we cannot guarantee that these parties will maintain the confidentiality of our proprietary information in the course of future employment or working with other business partners. We develop,

##### Table of Contents

manufacture and sell our products in Asia 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 intellectual
property and the proprietary rights of third parties, which may expose us to litigation and prevent us from selling our products.

Vigorous protection and pursuit of intellectual property rights or positions characterize the semiconductor industry. This often results in expensive and lengthy litigation. We, and our customers or suppliers, may be accused of infringing
patents or other intellectual property rights owned by third parties in the future. 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, or find appropriate licenses on reasonable
terms or at all.

Patent disputes in the semiconductor industry are often settled through cross-licensing arrangements. Our portfolio of
patents may not have the breadth to enable us to settle an alleged patent infringement claim through a cross-licensing arrangement. We may therefore be more exposed to third party claims than some of our larger competitors and customers.

The majority of our customers are 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 significant debt in the form of senior convertible notes.

We have $68.3 million of 2.25% senior convertible notes outstanding. Our debt could materially and adversely affect our ability to obtain financing for
working capital, acquisitions or other purposes, and could make us 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 October 15, 2025, we are obliged to repay the full remaining principal amount of the notes that have not been converted into our common
stock, but we are also subject to certain triggering events that may cause the notes to be repaid earlier.

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. 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.

We expect that the price of our common stock will continue to fluctuate significantly, as it has in the past.
In particular, 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. In addition, we could incur substantial punitive and other damages relating to such litigation.

Provisions in Delaware law, our charter documents and our stockholder rights plan may delay or prevent another entity from acquiring us without the consent of our Board of Directors.

We adopted a stockholder rights plan in 2001, pursuant to which we declared a dividend of one share purchase right for each outstanding share of common
stock. If certain events occur, including if an investor tenders for or acquires more than 15% of our outstanding common stock, stockholders (other than the acquirer) may exercise their rights and receive $650 worth of our common stock in exchange
for $325 per right, or we may, at our option, issue one share of common stock in exchange for each right, or we may redeem the rights for $0.001 per right. The issuance of the rights could have the effect of delaying or preventing a change in
control of us.

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. Delaware law imposes some restrictions on mergers and other business combinations between us and any holder of 15% or more of our outstanding common stock.

Although we believe these provisions of our charter documents, 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.

We lease properties in 23 locations
worldwide totaling approximately 592,000 square feet. Approximately 33% of the space we leased was excess at December 28, 2008. Approximately 73% of the excess space has been subleased and we are actively pursuing opportunities to sublease or
negotiate our exit from the remaining excess facilities.

We lease approximately 108,000 square feet in Santa Clara, California, to house
our US design, engineering, sales and marketing operations.

Our Canadian operations are primarily located in Burnaby, British Columbia
where we lease approximately 173,000 square feet of office space in three separate buildings. This location supports a significant portion of our product development, manufacturing, marketing, sales and testing activities.

In addition to the two major sites in Santa Clara and Burnaby, during 2008 we also operated nine additional research and development centers: two in
Canada, four in the US, one in Bangalore, India, one in Herzliya, Israel and one in Shanghai, China.

We have twelve sales/operations
offices located in Europe, Asia, the Caribbean and North America.

Stockholder Derivative Lawsuits

Three derivative actions have been filed against the Company, as a nominal defendant, and various current and former officers and/or
directors: (1) Meissner v. Bailey, et al., Santa Clara Superior Court Case No. 1-06-CV-071329 (filed September 18, 2006); (2) Beiser v. Bailey, et al., United States District Court for the Northern District of
California Case No. 5:06-CV-05330-RS (filed August 29, 2006); and (3) Barone v. Bailey, et al., United States District Court for the Northern District of California (the Federal Court) Case
No. 4:06-CV-06473-SBA (filed October 16, 2006). On November 21, 2006, the Beiser and Barone actions were consolidated into one case. On January 18, 2007, the Santa Clara County Superior Court in California ordered that
the Meissner action be stayed pending the outcome of the consolidated, federal Beiser/Barone action.

The Beiser/Barone plaintiffs generally
allege that various current and former Company directors and/or officers breached their duty of loyalty and/or duty of care to the Company and its stockholders in connection with improperly dating certain employee stock option grants and that these
purported breaches of fiduciary duties caused harm to the Company. The plaintiffs seek to recover damages on behalf of the Company. They also allege violations of federal securities laws. The Company is a nominal defendant, but any
recovery in the litigation would be paid to the Company, rather than to its stockholders. The defendants have entered into joint defense arrangements.

The defendants moved to dismiss the Beiser/Barone action on various legal grounds including that the plaintiffs failed to state a claim and failed to plead with particularity facts establishing that a litigation
demand on the board of directors of the Company would have been futile at the time they commenced the derivative lawsuit. The Federal Court dismissed the consolidated complaint on August 22, 2007 and gave plaintiffs leave to amend.
The Federal Court dismissed the plaintiffs first amended consolidated complaint on May 8, 2008 and permitted plaintiffs leave to amend one last time. Defendants moved to dismiss the second amended complaint which motions were
to be heard on August 20, 2008.

On July 15, 2008, Ian Beiser, a named plaintiff in the Beiser/Barone action, filed a complaint
in the Delaware Court of Chancery, and it was served on July 18, 2008, compelling the Company to permit plaintiff to inspect and make copies of the Companys books and records. On August 5, 2008, the plaintiffs moved to stay the
Federal Court action pending the books and records action. The Federal Court granted the motion to stay on August 13, 2008, which removed from the calendar the hearing on defendants motions to dismiss, previously scheduled for
August 20, 2008.

On December 11, 2008, the Delaware Court of Chancery heard arguments on the books and records demand and the
parties are awaiting the Courts order.

|ITEM 7. | Managements Discussion and Analysis of Financial Condition and Results of Operations.
|------- | --------------------------------------------------------------------------------------

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

OVERVIEW

We generate revenues from the sale of semiconductor devices that we have designed and developed or acquired. Almost all of our revenues in any given year
come from the sale of semiconductors that are developed prior to that year. For example, 99% of our revenues in 2008 came from parts developed or acquired in 2007 and earlier. After an individual product is released for production and announced it
may take several years before that product generates any significant revenues.

Our current revenues are generated by a portfolio of
approximately 350 products. Our diverse product portfolio services a number of key end markets: the Enterprise Networking market which includes our products and solutions that enable the high-speed interconnection of servers, switches and storage
devices that comprise these systems so that large quantities of data can be stored, managed and moved securely; the Wide Area Network Infrastructure market whereby our products and solutions are used in networking equipment such as multi-service
switches and edge routers that gather and process signals in different protocols, and then transmit them from to the next destination as quickly and efficiently as possible; and the Access Networks market which encompasses both wired and wireless
equipment that aggregates data traffic from enterprises and homes and transmits it to the central offices in the metropolitan area of the network.

We invest a substantial amount every year for the research and development of new semiconductor devices. We determine the amount to invest in the development of new semiconductors based on our assessment of the future market opportunities
for those components, and the estimated return on investment. To compete globally we must invest in businesses and technologies that are both growing in demand and are cost competitive in the geographic markets that we serve. Going forward, we plan
to continue to focus on finding innovative solutions to meet our customers needs while finding further operational efficiencies.

We
continue to expand our storage product offerings. A leading OEM customer is expected to begin volume production of our 6 Gbps SAS 2 RAID-on-Chip in 2009. Additionally, our partnership with IBM for the joint development of RAID technology is
progressing well and we expect the products developed through this partnership will provide future growth for our storage business in 2010. We continue to benefit from our acquisition of the Storage Semiconductor Business from Avago in 2006 as we
incorporate Fibre Channel controllers that we acquired with the SAS disk-interconnect products that we designed. For example, follow on products include our 8 gigabit Fibre Channel controller products, which improve data access times that have been
made more challenging by data consolidation through virtualization and fixed content storage. These products are backward compatible with our 4 Gbps Fibre Channel products, allowing our customers to preserve their software investments.

We continue to penetrate Asian markets with our Fibre-To-The-Home (FTTH) products. While our Ethernet Passive Optical Network
(EPON) solutions are firmly entrenched in Japan, we expanded our FTTH presence into China and Korea in 2008. In China, our EPON products are gaining traction in the marketplace as some of the Chinese carriers deploy EPON field trials. In
Korea, we have introduced our second generation Gigabit Passive Optical Network (GPON) devices which will enable carriers to incorporate triple-play GPON systems into existing equipment designs.

We are also offering customers a multi-service fibre access gateway solution with an integrated GPON interface. This product will enable carriers to
expand high definition video offerings to consumers through mass deployment of higher bandwidth applications such as video picture sharing, peer-to-peer and data storage.

We are closely aligning with leading OEM customers supplying carriers who are investing in their networks
to enable delivery of residential video services. We are well positioned for these network upgrade opportunities with solutions that have high data throughput and require lower power for our customers.

With regard to our communications business, we continue to see the convergence of networks and build-outs driving service provider requirements and large
contracts for metro-optical transport and access equipment. We are seeing growth in demand for our access products as service providers expand their wired and wireless networks around the world.

We expect our SOC solutions to continue to penetrate the laser printer market as well as the network-attached storage market for small to medium sized
businesses. We will also continue to pursue ASIC design wins with our leading OEM customers in this market.

Net Revenues ($ millions)



|             |  |      |       |        |    |   |      |   |        |  |   |      |  |   |      
|------------ |  | ---- | ----- | ------ | -- | - | ---- | - | ------ |  | - | ---- |  | - | -----
|             |  | 2008 |       | Change |    |   | 2007 |   | Change |  |   | 2006
|Net revenues |  | $    | 525.1 |        | 17 | % |      | $ | 449.4  |  | 6 | %    |  | $ | 425.0

Net revenues for 2008 increased $75.7 million, or 17%, compared to net revenues for 2007. Revenues
generated from the Enterprise Networking market, which is served by our storage and microprocessor-based SOC products increased 19% compared to 2007. Revenue generated from the Wide Area Network Infrastructure (WAN) market remained flat.
Revenues generated from the Access Networks market increased by 74%.

The growth in our Enterprise Networking market was generally
attributable to an increase in storage capacity upgrades and information management solutions expenditures in the market place in 2008 compared to 2007. The sales of our microprocessor-based SOC products increased in 2008 compared to 2007 primarily
due to increased activity in the laser printer market. The revenues from our Access Networks market grew due to the growth driven by sales growth in Asia and the emerging markets, particularly China. In 2008, there was an increase in shipments to
our Chinese customers using Ethernet Passive Optical Network devices for field trials in the China market. In addition, shipments of our FTTH products to Japan and Korea increased as carriers continue to build out their networks.

An increase in net revenue of $4.2 million is also attributable to changes in 2007 in how we conduct business with one of the international entities of a
certain distributor to a sell-through basis, which is consistent with our revenue practice for business conducted with that distributor.

Net revenues for 2007 increased $24.4 million, or 6% compared to net revenues for 2006. In 2007, the products we acquired from Passave and the Storage Semiconductor Business from Avago contributed an incremental $18.2 million to our net
revenues due to full versus partial year of revenues in 2006. However, there was a year over year decrease in revenues from the acquired Storage Semiconductor Business as certain products reached their end of life. We had an 8% growth in our
revenues generated from the Enterprise Networking market, which is served by our storage and microprocessor-based SOC products in 2007 when compared to 2006. Revenue generated in 2007 from the WAN Infrastructure market decreased by 12% and the
revenues generated in 2007 from the Access Networks market decreased by 10% when compared to 2006. A decrease in net revenues of $4.2 is also attributable to changes in 2007 in how we conduct business with one of the international entities of a
certain distributor to a sell-through basis, which is consistent with our revenue practice for business conducted with that distributor, as mentioned above.

Over the past three years, we have seen significant growth in net revenues generated in Asia. Net revenues from Asia were 73% of total net revenues in 2008, 65% of total net revenues in 2007 and 57% of total net
revenues in 2006. We attribute this trend primarily to our increasing presence in the FTTH market, which is concentrated in Japan, Korea, China and Taiwan, and increased manufacturing outsourcing into Asia by our OEM customers.

Total gross profit for 2008 increased by $52.3 million over gross profit in 2007. The gross profit
as a percentage of revenues was approximately 65% in 2008 and 2007.

While product mix can influence our gross profit as a percentage of
revenue from period to period, our underlying gross profit percentage in 2008 remained consistent with that in 2007 as changes in average selling price decreased in approximately the same proportion as decreases in manufacturing costs.

Total gross profit for 2007 increased by $12.6 million over gross profit in 2006. The acquisitions we completed in 2006 and growth in sales of our
microprocessor and organic storage products had positive impacts on our gross profit, partially offset by the impact of declines in sales of our telecommunications products on gross profit.

The most significant items impacting the change in gross margin as a percentage of net revenues from 2006 to 2007 were:



| |  |  | a change in product mix away from our telecommunications products toward our storage, FTTH and SOC products, which decreased gross margin by approximately 2%;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | in 2006, we sold inventory acquired from the Storage Semiconductor Business of Avago that was valued at its selling price, less related selling costs, as opposed to
the lower manufacturing cost; there was no such expense incurred in 2007 and our gross margin increased by approximately 2% compared to 2006; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the combined impact of increased obsolescence provision and royalty expense decreased gross margin by approximately 1%.

Research and Development Expenses

Our research and development (R&D), expenses were $157.6 million, or $1.5 million and 1% lower in 2008 compared to 2007. Due to
restructuring activities undertaken in the first quarter of 2007, our payroll-related costs decreased $5.9 million. Offsetting these decreases, we incurred $0.8 million in higher materials costs, including higher outside consultant services due to
completing more tapeouts on smaller geometries in 2008

##### Table of Contents

compared to 2007, as well, the IBM RAID R&D programs which began in first quarter of 2008, added additional costs in 2008. In addition, there was a $1.9
million increase in infrastructure related expenses due to normal maintenance of equipment and design related software tools, $1.7 million increase in the amortization of purchased intangibles mainly due to increased tools relating to the IBM RAID
project and an increase of $0.1 million in other costs.

Our R&D expenses were flat in 2007 compared to 2006. Payroll costs increased
by approximately $0.3 million due to an increase in stock based compensation expense. Office and facilities costs increased by $0.8 million due to supporting our Israel R&D facility for a full year in 2007 compared to seven months in 2006, and
operating our Shanghai R&D facility that opened in 2007. These increases were partially offset by $0.6 million in lower material costs.

Selling, General and Administrative Expenses

Our selling, general and administrative (SG&A) expenses were
$7.0 million, or 7% lower in 2008 compared to 2007. The primary reason for the net decrease in SG&A expenses is the restructuring activities undertaken in the first quarter of 2007. As a result, payroll-related costs and facilities-related costs
were lower by $4.9 million and $2.5 million, respectively. Professional fees were $2.1 million lower in 2008 compared to 2007, mainly due to settlement of a litigation matter in August 2007. Other SG&A costs were $2.5 million higher in 2008
compared to 2007. The primary reasons for the increase were that in 2007 we received a credit of $2.8 million arising from the favorable settlements of both a payroll tax matter with the United Kingdom tax authorities and a capital tax refund.

Our SG&A expenses were lower by $1.9 million, or 2%, in 2007 compared to 2006.

In 2006, we accrued $2.4 million for payroll withholding taxes associated with transactions from 2000 and prior. In 2007, we settled this matter for $0.2
million and reversed the remaining accrual, thus reducing SG&A by $4.6 million compared to 2006. Partially offsetting this reduction in costs was a $2.2 million increase in professional fees related to our settlement of litigation inherited from
our Passave acquisition and the ongoing examination of our historic transfer pricing practices and policies of certain companies within the PMC-Sierra group. In 2007, we also received a capital tax refund of $0.5 million.

While we incurred increased payroll-related costs during the year due to the significant increase in the Canadian dollar relative to the U.S. dollar,
this was offset by decreases in our stock-based compensation expense.

Amortization of purchased intangible assets and in-process
research and development

Amortization of intangible assets acquired from the Storage Semiconductor Business and Passave was $18.9
million and $20.4 million, respectively, for 2008.

Passave

A portion of the purchase price for Passave was allocated to in-process research and development (IPR&D) projects and was expensed in the second quarter of 2006 because technological feasibility had
not been established and no future alternative uses existed. Projects acquired from Passave included EPON, and Analog Front End (AFE) products, which are based on technology that provides a low-cost method of deploying optical access
lines between a carriers central office and a customer site and which provide further enhancements and functionality to the existing EPON series, and GPON products, which are more complex and support multiple protocols and provide further
enhancements to the GPON series.

At the acquisition date of Passave, early revisions of the AFE products were in the final stage of
testing and had been sent out to be manufactured or taped out, with estimated costs to complete of approximately

$0.4 million. At the end of the second quarter of 2007, production testing on AFE products was complete with costs in line with expectations, and no
further development efforts were required. The EPON products are also complete and released to production, with no additional costs required to complete. By the end of the third quarter of 2007, the EPON products were shipping to customers.

GPON products were in the early design and prototype stages at acquisition, with estimated costs to complete of approximately $4.5 million
at the acquisition date. With costs incurred in line with expectations, we are now shipping these products to customers. Another product was incorporated with other PMC technology and was completed in 2008. This product has earned several design
wins, with shipments expected to begin in 2009.

Storage Semiconductor Business

A portion of the purchase price for the Storage Semiconductor Business was allocated to IPR&D projects and was expensed in the first quarter of 2006
because technological feasibility had not been established and no future alternative uses existed. Projects acquired and expensed include three next-generation Tachyon storage protocol products.

At the acquisition date, two of the next-generation Tachyon products had been taped out, with estimated costs to complete of approximately $0.8 million.
These products are now in production, with costs incurred in line with expectations.

The third next-generation Tachyon product and a
multi-protocol storage controller were in the early design stage at acquisition, with estimated costs to complete of approximately $10 million. We expect the third next-generation Tachyon product to ship in production volumes in 2009. By the end of
the first quarter of 2006, the multi-protocol storage controller product was in the development stage, and based on feedback from our customers, we re-directed our design resources from this project to the ROC controller for the server-attached
storage market, and the 8 Gbps Fibre Channel controllers for high-performance storage systems in the SAN and NAS markets, which went into production in 2009.

Restructuring Costs and Other Charges

The activity related to excess facility and severance accruals
under our restructuring plans during the three years ended December 28, 2008, by year of plan, were as follows:

2007

In the first quarter of 2007, we initiated a cost-reduction plan that involved staff reductions of 175 employees at various sites and the closure of design centers in Saskatoon, Saskatchewan and Winnipeg, Manitoba. We also vacated excess
office space at our Santa Clara facility. PMC continued to rationalize costs in the fourth quarter of 2007 by reducing headcount by 18 employees primarily at the Burnaby facility.

In 2008, we recorded a net reduction of our accrual for excess facilities by $0.2 million, as we fulfilled a portion of these obligations and made
payments of $0.9 million related to the 2007 plan. To date, we have incurred $10.3 million in termination and relocation costs, $2.6 million for excess facilities and contract termination cost and $2.6 million in asset impairment charges.

We have made payments of $12.1 million in connection with this plan. As of December 30, 2008, $7 thousand in severance costs remained
to be paid and payments related to the excess facilities may extend until 2011.

We initially expected to save approximately $16 million in
payroll-related costs on an annualized basis. We achieved the prorated portion of these expected cost savings in 2008. We continued to contain costs in accordance with our 2007 restructuring plan, however, we also initiated new R&D programs in
2008 which resulted in increases in payroll-related costs of approximately $4.9 million that partially offset the cost savings anticipated by the 2007 restructuring plan.

2006

In the third quarter of 2006, we closed our Ottawa development site in order to reduce operating
expenses and the space was vacated by the end of the fourth quarter of 2006. Approximately 35 positions were eliminated, primarily from research and development, resulting in one-time termination benefit and relocation costs of $2.2 million, and
$2.0 million for excess facilities. We also eliminated ten positions from research and development in our Portland development site, resulting in restructuring charges of $1.4 million, comprised of $0.8 million in severance, $0.3 million for excess
facilities, $0.1 million for contract termination and $0.2 million in asset impairment.

In 2008, we recorded a net addition accrual of $0.1 million for our excess facilities, as the original
assumptions regarding possible sublease of the exited facilities were not realized, and made payments of $0.5 million related to the 2006 plan.

To date, we have made payments relating to these activities of $4.4 million. As of December 28, 2008, all severance costs have been paid. Payments related to the excess facilities will extend to 2010.

2005

During 2005, we completed various restructuring
activities aimed at streamlining production and reducing operating expenses. In the first quarter of 2005, we recorded restructuring charges of $0.9 million in severance costs related to the termination of 24 employees across all business functions.
In the second quarter of 2005, we expanded the workforce reduction activities initiated during the first quarter and terminated 63 employees from research and development located in the Santa Clara facility. In addition, we consolidated two
manufacturing facilities (Santa Clara, California and Burnaby, British Columbia) into one facility (Burnaby), which involved the termination of 26 employees from production control, quality assurance, and product engineering. As a result, we
recorded total second quarter restructuring charges of $7.6 million, including $6.7 million for termination benefits and a $0.9 million write-down of equipment and software assets whose value was impaired as a result of these plans. In the third
quarter of 2005, we consolidated our facilities and vacated excess office space in the Santa Clara location, and recorded a restructuring charge of $5.3 million for excess facilities and an additional $0.1 million in severance costs.

In the first quarter of 2006, we continued the workforce reduction plans initiated in 2005 and recorded $1.6 million in restructuring charges related to
the termination of 19 employees, primarily from research and development, in the Santa Clara facility. During the third quarter of 2006, we reduced our estimated severance accrual related to the 2005 workforce reduction activities by $0.4 million,
and increased the accrual for excess facilities related to the 2005 restructuring by $0.8 million. We further increased our accrual for excess facilities by $0.5 million in the fourth quarter of 2007. In 2008, we recorded an additional accrual for
excess facilities of $1.1 million, as the original assumptions regarding possible sublease of the exited facilities were not realized, and made payments of $1.4 million related to the 2005 plan.

To date, we have made payments relating to these activities of $13.4 million. As of December 28, 2008, all severance costs have been paid. Payments
related to the excess facilities will extend to 2011.

2003 and 2001

In 2003 and 2001, we implemented three restructuring plans aimed at focusing development efforts on key projects and reducing operating costs in response to the severe and prolonged economic downturn in the
semiconductor industry. Our assessment of the market demand for our products and the development efforts necessary to meet this demand, were key factors in the decisions to implement these restructuring plans. As end markets for our products had
contracted, certain projects were curtailed in an effort to cut costs. Cost reductions in all other functional areas were also implemented, as fewer resources were required to support the reduced level of development and sales activities during
these periods.

The January 2003 restructuring included the termination of 175 employees and the closure of design centers in Maryland,
Ireland and India, and vacating office space in the Santa Clara facility. To date, we have recorded restructuring charges of $18.3 million in accordance with Statement of Financial Accounting Standard No. 146, Accounting for Costs Associated
with Exit or Disposal Activities, including $1.5 million for asset write-downs. These charges related to workforce reduction, lease and contract settlement costs, and the write-down of certain property, equipment and software assets whose value
was impaired as a result of this restructuring plan. We have disposed of the property improvements and computer equipment, and software licenses that have been cancelled or that are no longer being used. In 2006, we reversed $2.3 million of this
restructuring accrual because certain

floors in the Santa Clara facility that had been vacated in 2003 were re-occupied in 2006 due to the addition of personnel that occurred with the acquisition
of the Storage Semiconductor Business. We reversed a further $0.5 million in 2007, as we completed a portion of the lease obligation at this site.

The October 2001 restructuring plan included the termination of 341 employees, the consolidation of excess facilities, and the curtailment of certain research and development projects, resulting in a restructuring charge of $175.3 million,
including $12.2 million of asset write-downs. Due to the continued downturn in real estate markets, we recorded additional provisions for abandoned office facilities of $1.3 million in the fourth quarter of 2004.

In the first quarter of 2001, we recorded a charge of $19.9 million for a restructuring plan that included the termination of 223 employees across all
business functions, the consolidation of a number of facilities and the curtailment of certain research and development projects. Due to the continued downturn in real estate markets, we recorded additional provisions for abandoned office facilities
of $2.2 million in the fourth quarter of 2004, $0.8 million in the third quarter of 2006 and $0.9 million in the fourth quarter of 2007. In 2008, we recorded a net reduction of our accrual for excess facilities of $0.7 million, as we fulfilled a
portion of these obligations, and made payments of $1.3 million related to the 2001 plan.

To date, we have made cash payments of $12.7
million and $178.0 million related to the 2003 and 2001 plans, respectively. We have completed the activities contemplated in these restructuring plans, but have not yet terminated the leases on all of its surplus facilities. Efforts to exit these
sites are ongoing, but the payments related to these facilities could extend to 2011.

Interest income, net

Our net interest income for 2008, 2007 and 2006 was $4.9 million, $9.9 million and $9.0 million respectively.

In 2008, we repurchased $156.7 million principal amount of our senior convertible notes for $138.3 million. The repurchases significantly decreased our
cash balance. During 2008, the Federal Reserve Board cut the overnight interest rate by four percentage points. In addition, for the fourth quarter of 2008, we did not accrue any interest income related to our investments in the Reserve Funds due to
the status of the Reserve Funds (see Liquidity and Capital Resources). The combined effect of these factors contributed to our lower interest income for the year.

##### Table of Contents

In 2007, we did not have any comparable investing activities that consumed significant cash and we were
able to increase our cash balances through operations during the year. Partially offsetting the impact of the higher cash balances was reduced interest income from prior year tax refunds.

In the first quarter of 2006, we acquired the Storage Semiconductor Business for $431.3 million in cash, which lowered our cash balance and resulted in a
significant decrease in interest income that year.

Foreign exchange gain (loss)

Foreign exchange gain was $8.1 million in 2008 compared to a loss of $18.5 million in 2007 and $0.1 million in 2006. The foreign exchange gain (loss) for
all years presented relates primarily to the re-measurement each period of accrued income tax amounts.

In 2008, the U.S. dollar
strengthened against foreign currencies, in the jurisdictions in which we operate, which generated foreign exchange gains. In 2007, the U.S. dollar weakened against these foreign currencies, generating foreign exchange losses.

Gain on repurchase of senior convertible notes and amortization of debt issue costs

In 2005, we issued $225.0 million 2.25% senior convertible notes. In 2008, we repurchased $156.7 million principal amount of our senior convertible notes
for $138.3 million and expensed $3.2 million of related unamortized debt issue costs and transactions costs resulting in a net gain of $15.2 million. We also recognized amortization of debt issue costs of $0.6 million, $1.0 million, $1.0 million for
2008, 2007 and 2006 respectively.

Asset impairment

In 2008, we recorded $4.3 million for an asset impairment related to a supplier contract termination.

Recovery on Investments

In 2008, we received $0.4 million as recovery on a previously booked investment loss related to our
past investment in a private company.

Loss on Investment Securities

At December 28, 2008, we held $209.7 million in investments in shares of the Reserve Funds, net of the recorded impairment of $11.8 million that we
recognized in the third quarter of 2008.

During 2006, we sold our investment in Ikanos Communications Inc. for proceeds of $5.1 million
and recorded a gain of $3.1 million, which has been included in (Loss) gain on sale of investments on the Statement of Operations. Also included in (Loss) gain on sale of investments were a gain on sale of another investment, as well as an
impairment loss of $3.2 million on our investment in a private company, and a $1.3 million loss on sales of other short-term investments that were redeemed prior to maturity to fund the acquisition of the Storage Semiconductor Business.

Provision for Income Taxes

Our
provision for income taxes for the year ended December 28, 2008 was a $70.0 million recovery, resulting in an effective tax rate of negative 110% on net income of $63.9 million. The recovery was primarily as a result of one of the
Companys foreign subsidiaries settling several ongoing tax matters for less than had been accrued as part of its liability for unrecognized tax benefits, resulting in the recognition of a $124.1 million tax benefit. In addition, the Company
accrued $35.2 million (including associated interest) relating to an ongoing

##### Table of Contents

liability arising from the examination of our existing transfer pricing practices prior to the settlement noted above, $28.1 million of income tax from
normal operations (offset by investment tax credits of $19.5 million), $5.8 million deferred tax expense from an unrealized gain arising from foreign currency translation pertaining to a foreign subsidiary, and $4.5 million increase in tax from
various items, including deferred taxes, minimum taxes and revisions of prior estimates.

Our provision for income taxes for the year ended
December 30, 2007 was $16.8 million, resulting in an effective tax rate of 52% on a net loss of $32.3 million. Despite this net loss, income taxes were incurred primarily from a $28.0 million additional accrual relating to an ongoing FIN 48
liability arising from the examination of our historic transfer pricing policies and practices of certain companies within the PMC Group by a certain tax authority. Of the $28.0 million increase in our FIN 48 liability, $13.0 million is related to
arrears interest. Our FIN 48 liability is partially offset by available investment tax credits of $18.0 million. The remainder of the provision for income taxes primarily relates to $6.0 million of deferred taxes recorded with respect to a past
acquisition and net $1.0 million due to various items, including revisions of prior estimates.

Our provision for income taxes for the year
ended December 31, 2006 was $49.2 million on a net loss before taxes of $50.7 million, or 97% of the net loss before taxes, compared to a United States federal statutory tax rate of 35%. Our effective tax rate represents a rate that is
applicable to all of our operations crossing multiple tax jurisdictions with tax rates that are different than the United States federal statutory tax rate. A significant portion of our net loss for 2006 consisted of expenses that have no
associated tax benefits due to their non-deductibility and the fact that deferred tax assets primarily relating to the operating loss carryforwards in the U.S. are fully offset by a valuation allowance. These expenses include amortization of
non-deductible intangible assets and in-process research and development, and stock-based compensation. Our effective tax rate in all years presented reflects recoveries and refunds of prior year taxes paid and tax credits received by our Canadian
subsidiary for research and development expenses incurred, offset by valuation allowances on losses carried forward.

Our estimated tax
provision rate increased significantly at the end of 2006 due to an increase in our estimated tax liability following receipt in 2007 of a written communication from a tax authority examining the historical transfer pricing policies and practices of
certain companies within the PMC-Sierra group. As a result, we increased our provision for periods prior to 2006 by $29.9 million. We recorded $7.1 million tax expense in the first quarter of 2006 for withholding and other taxes on the repatriation
of funds used to purchase the Storage Semiconductor Business and recorded $3.8 million in net deferred tax expense associated with both of the acquisitions of the Storage Semiconductor Business and Passave, Inc..

See Note 15 to the Consolidated Financial Statements for additional information regarding income taxes.

Critical Accounting Policies and Estimates

General

Managements Discussion and Analysis of Financial Condition and Results of Operations is based upon our
Consolidated Financial Statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and assumptions that affect the
amounts we report as assets, liabilities, revenue and expenses, and the related disclosure of contingent assets and liabilities. Management bases its estimates on historical experience and on various other assumptions that are reasonable in the
circumstances. These estimates could change under different assumptions or conditions.

Our significant accounting policies are outlined in
Note 1 to the Consolidated Financial Statements. In managements opinion the following critical accounting policies require the most significant judgment and involve complex estimation. We also have other policies that we consider to be key
accounting policies, such as



38



---

##### Table of Contents

our policies of revenue recognition, including the deferral of revenues on sales to major distributors; however these policies do not meet the definition of
critical accounting estimates as they do not generally require us to make estimates or judgments that are difficult or subjective.

Valuation of Goodwill and Intangible Assets

The purchase method of accounting for acquisitions requires estimates and
assumptions to allocate the purchase price to the fair value of net tangible and intangible assets acquired, including in-process research and development (IPR&D). The amounts allocated to IPR&D are expensed immediately. The
amounts allocated to, and the useful lives estimated for, other intangible assets, affect future amortization. There are a number of generally accepted valuation methods used to estimate fair value of intangible assets, and we use primarily a
discounted cash flow method, which requires significant management judgment to forecast the future operating results and to estimate the discount factors used in the analysis. If assumptions and estimates used to allocate the purchase price or used
to access impairment prove to be inaccurate, future asset impairment charges could be required.

Goodwill and intangible assets determined
to have indefinite lives are not amortized, but are subject to an annual impairment test. To determine any goodwill impairment, we perform a two-step process on an annual basis, or more frequently if necessary, to determine 1) whether the fair value
of the relevant reporting unit exceeds carrying value and 2) the amount of impairment loss, if any. We review our intangible assets for impairment whenever events or changes in circumstances indicate that their carrying value may not be recoverable.
Measurement of an impairment loss is based on the fair value of the asset compared to carrying value.

We performed an annual test for
impairment of goodwill and intangible assets in the fourth quarter of 2008 and determined that there was no impairment. The assumptions used to test for impairment, including expected revenues, discount rates, and terminal values, are highly
subjective. Valuation models are sensitive to changes in assumptions, and therefore changes in these assumptions in the future could result in significant impairment charges or changes to our expected amortization.

Stock-based compensation

Since
January 1, 2006, we recognize compensation expense for all share-based payment awards. Under SFAS 123(R) we measure the fair value of awards of equity instruments and under SFAS 123(R) recognize the cost, net of an estimated forfeiture rate, on
a straight-line basis over the period during which services are provided in exchange for the award, generally the vesting period.

Calculating the fair value of stock-based compensation awards requires the input of highly subjective assumptions, including the expected life of the awards and expected volatility of PMCs stock price. Expected volatility is a
statistical measure of the amount by which a stock price is expected to fluctuate during a period. Our estimates of expected volatilities are based on a weighted historical and market-based implied volatility. In order to determine the expected life
of the awards, we use historical data to estimate option exercises and employee terminations; separate groups of employees that have similar historical exercise behavior, such as directors or executives, are considered separately for valuation
purposes. The expected forfeiture rate applied in calculating stock-based compensation cost is estimated using historical data.

The
assumptions used in calculating the fair value of stock-based awards involve estimates that require management judgment. If factors change and we use different assumptions, our stock-based compensation expense could change significantly in the
future. In addition, if our actual forfeiture rate is different from our estimate, our stock-based compensation could change significantly in the future. See Notes 1 and 5 to the Consolidated Financial Statements for further information on
stock-based compensation.

Restructuring chargesFacilities

In calculating the cost to dispose of our excess facilities we 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 of sublease revenues. This calculation includes an estimate of the timing and costs of each lease to be terminated, the amount of operating costs for the affected
facilities, and the timing and rate at which we might be able to sublease each site. To form our estimates for these costs we performed an assessment of the affected facilities and considered the current market conditions for each site.

Restructuring activities during the past several years have resulted in facilities charges as follows:

During 2001, we recorded total charges of $155.0 million for the restructuring of excess facilities as part of restructuring plans implemented that year.
The total remaining estimate of $3.9 million related to the 2001 restructuring plans represents 100% of the estimated total future operating costs and lease obligations for the affected sites.

In the first quarter of 2003, we announced a further restructuring of our operations, which resulted in the closing of an additional four product
development sites and the recording of $9.6 million charge related to these facilities. During 2006 we reversed $2.3 million of this provision because a portion of the space was re-occupied. During 2007, we reversed the remaining $0.5 million of
this provision as we subleased space and were able to terminate our lease obligations earlier than we had previously estimated.

In the
third quarter of 2005, we recorded charges of $5.3 million for the restructuring of excess facilities in connection with the restructuring plans implemented in 2005. The total remaining estimate of $3.3 million represents 100% of the estimated total
future operating costs and lease obligations for the site.

In the third quarter of 2006, we announced the closure of our development site
in Ottawa and recorded total charges of $2.3 million for the restructuring of excess facilities. During 2007, we reversed $0.4 million of this provision because we subleased a portion of this space earlier than originally anticipated. The total
remaining estimate of $0.6 million represents 100% of the estimated total future operating costs and lease obligations for the site.

In
the first quarter of 2007, we recorded charges of $2.8 million related to the closure of our design centers in Saskatoon and Winnipeg, Canada, and exit of a portion of our Santa Clara facility. The total remaining estimate of $1.9 million represents
100% of the estimated total future operating costs and lease obligations for the site.

Income Taxes

In estimating our annual effective tax rate we review our forecasted net income for the year by geographic area and apply the appropriate tax rates. We
also consider the income tax credits and net operating losses, if any, available in each tax jurisdiction.

Our operations are conducted in
a number of countries with complex tax legislation and regulations pertaining to our activities. We have recorded income tax liabilities based on our estimates and interpretations of those regulations for the countries we operate in. However, our
estimates are subject to review and assessment by the tax authorities and the courts of those countries. For example, our estimated tax provision rate decreased significantly at the end of 2008 due to one of the Companys foreign subsidiaries
settling several ongoing tax matters for tax years 2000-2006. As a result, we recognized tax benefits of $124.1 million that was previously included in the liability for unrecognized tax benefits. The timing of any such review and final assessment
of our liabilities by local authorities is substantially out of our control and is dependent on the actions by those authorities in the countries we operate in. Any re-assessment of our tax liabilities by tax authorities may result in adjustments of
the income taxes we pay or refunds that are due to us.

##### Table of Contents

In certain jurisdictions 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 and certain foreign deferred tax assets.

Investment in Cash Equivalents, Short Term Investments and Investment Securities

Our cash equivalents, short-term investments and investment securities are comprised solely of money market funds, which include only A1 and P1 or
equivalent-rated debt securities. At December 28, 2008, these securities had an estimated fair value of $278.9 million.

Beginning in
the first quarter of fiscal 2008, the assessment of fair value is based on the provisions of Statement of Financial Accounting Standard No. 157, Fair Value Measurements (SFAS 157). We determined the fair value of our money market
funds using quoted prices from active markets, quoted prices for similar assets from third-party sources and by performing valuation analyses. In determining if and when a decline in market value below the carrying value of our money market funds is
other-than-temporary, we evaluate on an ongoing basis the market conditions, trends of earnings, financial condition and other key measures for our investments. We assess impairment of our money market fund investments in accordance with FASB Staff
Position FAS 115-1, The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments.

During 2008, we
assessed the fair value of our money market funds by giving consideration to Level 2 and Level 3 inputs in accordance with the fair value hierarchy of SFAS 157 for the Reserve Funds and their underlying securities. Based on this assessment, we
recorded an impairment of the Reserve Funds of $11.8 million during the third quarter of 2008, incorporating the Reserve Funds valuation at zero for debt securities of Lehman Brothers held, and a net asset value of $0.97 per share communicated
by the Primary Fund. We reassessed the fair value of our investments in money market funds for the year-ended December 28, 2008 and there were no further impairments.

We reclassified our investment in shares of the Reserve Funds from Level 1 to Level 3 of the fair value hierarchy due to the inherent subjectivity and
significant judgment related to the fair value of the shares of the Reserve Funds and their underlying securities. Accordingly, we changed the valuation method from a market approach to an income approach.

In addition, due to the continuing redemption delays associated with the liquidation proceedings of the Reserve Funds, we reclassified all of these
shares from cash and cash equivalents to short-term investments (see Liquidity and Capital Resources).

Changes in market conditions and
the method and timing of the liquidation process of the Reserve Funds could result in further adjustments to the fair value and classification of these investments, and these changes could be material.

Business Outlook

We expect our revenues for
the first quarter of 2009 to be approximately $90 to $100 million based on typical order patterns. As in the past, and consistent with business practice in the semiconductor industry, a portion of our revenues are likely to be derived from orders
placed and shipped during the same quarter, which we call our turns business. Our turns business varies from quarter to quarter. In the fourth quarter of 2008, net orders booked and shipped within the quarter were approximately 18% of
quarterly sales, and we expect the turns percentage to be higher in the first quarter of 2009 compared with the fourth quarter of 2008.

We
anticipate our first quarter 2009 gross margin percentage to be in the range of 63% plus or minus 25 basis points including approximately $0.2 million stock-based compensation expense. As in past quarters this could vary depending on the volumes of
products sold, since many of our costs are fixed. Margins will also vary depending on the mix of products sold.

##### Table of Contents

We expect our first quarter 2009 research and development and selling, general and administrative
expenses to be approximately $59.7 million to $60.7 million respectively including stock-based compensation expense of approximately $4.7 million to $5.7 million. Therefore, we expect our first quarter core operating research and development and
selling, general and administrative expenses to be approximately $55.0 million.

We expect that we will continue to incur significant
amortization of purchased intangible assets related to our 2006 acquisitions in the first quarter of 2009.

We anticipate that net interest
income will be approximately zero in the first quarter of 2009 as interest income earned from our cash position will be offset by interest expense incurred on our outstanding senior convertible notes.

Liquidity and Capital Resources

Our principal
sources of liquidity are cash from operations, and our short term investments. We employ these sources of liquidity to support ongoing business activities, acquire or invest in critical or complementary technologies, purchase capital equipment,
repurchase and repay our senior convertible notes and finance working capital. The combination of cash, cash equivalents and short-term securities at December 28, 2008 and December 30, 2007 totaled $307.5 million and $364.9 million,
respectively. As of December 28, 2008 and December 30, 2007, we had $68.3 million and $225.0 million of senior convertible notes outstanding, respectively. In the future, we expect our cash on hand, from operations, and distributions from
the Reserve Funds to be our primary source of liquidity.

The short-term investments of $209.7 million held at December 28, 2008
relate to shares of the Reserve International Liquidity Fund, Ltd. (the International Fund) and the Reserve Primary Fund (the Primary Fund, together the Reserve Funds) for which we have outstanding redemption
orders. The Reserve Funds were AAA-rated money market funds which announced redemption delays and suspended trading in September 2008, during the severe disruption in financial markets. The Reserve Funds are in the process of liquidating their
portfolio of investments, which included securities of Lehman Brothers Holdings, Inc. (Lehman Brothers) which was downgraded and has filed for Chapter 11 bankruptcy protection. The Primary Fund has received an U.S. Security Exchange
Commission (the SEC) order providing that the SEC will supervise the distribution of assets from the fund. The redemptions from the International Fund are subject to pending litigation which could cause further delay in any redemption of
our investments.

Our investments in money market funds are classified in the consolidated balance sheet as follows:



|                       |  |                  |       |                  |   |

We expect distributions from the Reserve Funds will occur over the following 12 months as the
underlying investments held in the Reserve Funds mature and distributions are made from the funds through the liquidation process. Subsequent to December 28, 2008, we received $134.9 million as a partial distribution from the International
Fund.

Changes in market conditions and the method and timing of the liquidation process of the Reserve Funds could result in further
adjustments to the fair value and classification of these investments, and these changes could be material.

EstimatesInvestment in Cash Equivalents, Short Term Investments and Investment Securities for additional information.

Operating ActivitiesDuring the fiscal year 2008, we generated positive net operating cash
flows of $78.8 million, which was $12.4 million lower than the $91.2 million generated in fiscal 2007. The positive cash flow from operations generated in 2008 was primarily from net income, which included an impairment loss of the Reserve Funds of
$11.8 million, and the addback or deduction of non-cash items such as stock based compensation expense, depreciation and amortization expense, the gain on repurchase of our senior convertible notes and our net tax recovery.

Significant changes in working capital accounts in 2008 included:



| |  |  | a $6.9 million decrease in prepaids and other assets, which reflects expenses recognized in excess of cash additions to prepaids;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------



| |  |  | a $42.7 million of cash payments that reduced accounts payable and accrued liabilities, including $18.0 million payment related to settlement of a tax matter; due
to the downturn in the global economy throughout the last quarter of the year, we reduced our inventory purchases, which in turn, led to a lower overall accounts payable as of year end;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a $5.0 million decrease in our restructuring accruals as we paid severance and rent on excess facilities under our various restructuring plans; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a $2.5 million decrease in our deferred revenue as shipments to distributors slowed in the fourth quarter of fiscal 2008 due to the global economic downturn.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------

Investing ActivitiesNet cash used in investing activities of $222.4 million during fiscal 2008 included the
reclassification of the available-for-sale securities in the Reserve Funds from cash equivalents to short-term investments and long-term investment securities of $209.7 million in 2008.

We purchased $6.8 million of property, plant and equipment, and $5.9 million of intellectual property.

Financing activitiesNet cash used in financing activities in fiscal 2008 included the repurchase of our senior convertible notes for $139.3
million, and proceeds from the issuance of common shares under our stock option plans of $16.5 million.

As of December 28, 2008, we
have the following commitments:

On October 26, 2005, we issued $225 million aggregate principal amount of 2.25% senior convertible
notes due 2025 (the Notes) and have recorded these Notes as long-term debt. Issuance costs of $6.8 million have been deferred and are being amortized over seven years. During 2008, we repurchased $156.7 million principal amount of our
Notes for $138.3 million and expensed $3.2 million related to unamortized debt issue costs and transaction costs resulting in a net gain of $15.2 million. At December 28, 2008, $68.3 million of these Notes remained outstanding and $1.1 million
of unamortized debt issue costs were included in investments and other assets.

The notes rank equal in right of payment with our other
unsecured senior indebtedness and mature on October 15, 2025 unless earlier redeemed by us at our option, or converted or put to us at the option of the holders. Interest is payable semi-annually in arrears on April 15 and October 15
of each year, commencing on April 15, 2006. We may redeem all or a portion of the notes at par on and after October 20, 2012. The holders may require that we repurchase notes on October 15, 2012, 2015 and 2020 respectively.

Holders may convert the notes into the right to receive the conversion value (i) when our stock price exceeds 120% of the
approximately $8.80 per share initial conversion price for a specified period, (ii) in certain change in control transactions, and (iii) when the trading price of the notes does not exceed a minimum price level. For each $1,000 principal
amount of notes, the conversion value represents the amount equal to 113.6687 shares multiplied by the per share price of our common stock at the time of conversion. If the conversion value exceeds $1,000 per $1,000 in principal of notes, we will
pay $1,000 in cash and may pay the amount exceeding $1,000 in cash, stock or a combination of cash and stock, at our election.

We entered
into a Registration Rights Agreement with the holders of the Notes, under which we are required to keep the shelf registration statement effective until the earlier of (i) the sale pursuant to the shelf registration statement of all of the
Notes and/or shares of common stock issuable upon conversion of the Notes, and (ii) the expiration of the holding period applicable to such securities held by non-affiliates under Rule 144(k) under the Securities Act, or any successor
provision, subject to certain permitted exceptions.

We will be required to pay liquidated damages, subject to some limitations, to the
holders of the Notes if we fail to comply with our obligations to register the notes and the common stock issuable upon conversion of the notes or the registration statement does not become effective within the specified time periods. In no event
will liquidated damages accrue after the second anniversary of the date of issuance of the notes or at a rate exceeding 0.50% of the issue price of the notes. We will have no other liabilities or monetary damages with respect to any registration
default. If the holder has converted some or all of its notes into common stock, the holder will not be entitled to receive any liquidated damages with respect to such common stock or the principal amount of the notes converted.

Purchase obligations are comprised of commitments to purchase design tools and software for use in product development. Included in the purchase
commitments above is $18.1 million in design software tools, which will be spent between 2009 and 2010. We have not included open purchase orders for inventory or other expenses issued in the normal course of business in the purchase obligations
shown above. We estimate these other commitments to be approximately $11.3 million at December 28, 2008 for inventory and other expenses that will be received in the coming 90 days and that will require settlement 30 days thereafter.

We have a line of credit with a bank that allows us to borrow up to $0.8 million provided we maintain eligible investments with the bank
equal to the amount drawn on the line of credit. At December 28, 2008 we had committed $0.8 million under letters of credit as security for office leases.

We expect to use approximately $17.1 million of cash in 2009 for capital expenditures including purchases of intellectual property. Based on our current operating prospects, we believe that existing sources of
liquidity will be sufficient to satisfy our projected operating, working capital, capital expenditure, purchase obligations, and remaining restructuring requirements through the end of 2009.

Off-balance Sheet Arrangements

As of December 28, 2008, we had no off-balance sheet financing arrangements.

Recent Accounting Pronouncements

In May 2008, the Financial Accounting Standards Board (FASB) issued Staff Position Accounting Principles Board Opinion
14-1, Accounting for Convertible Debt Instruments That May Be Settled in Cash Upon Conversion (Including Partial Cash Settlements, (APB 14-1), which will change the accounting treatment for convertible securities which the issuer
may settle fully or partially in cash. Under APB 14-1, cash settled convertible securities will be separated into their debt and equity components. The value assigned to the debt component will be the estimated fair value, as of the issuance date,
of a similar debt instrument without the conversion feature, and the difference between the proceeds for the convertible debt and the amount reflected as debt, will be recorded as equity. As a result, the debt component will be recorded at a
discount from its face value, reflecting its below market coupon interest rate. The debt will subsequently be accreted to its face value over its expected term, with the accretion being reflected as additional interest expense in the statement of
operations. APB 14-1 is required to be adopted retrospectively, at the beginning of our 2009 fiscal year, in respect of convertible securities outstanding at the end of our 2008 fiscal year.

Our senior convertible notes (Notes) with a face value of $225 million were issued in October 2005 and bear interest at a rate of
2.25% per annum. At the date of issuance, our borrowing rate for similar debt instruments without any equity conversion features was estimated to be 8.0% per annum. Under APB 14-1, at the issuance date, the debt and equity components
would be $155.6 million and $69.4 million, respectively, before considering related issuance costs. The following table shows the effect of this new standard on the consolidated financial statements, had it been applied since the issuance date of
our Notes, and takes into account the repurchases of a portion of these Notes to December 28, 2008:

Based on the Notes outstanding as at December 28, 2008, additional interest expense arising from the
adoption of APB 14-1 is expected to be approximately $3 million annually. The debt discount is being accreted over the term to the earliest date at which the holders of the Notes may exercise redemption rights, which is October 15, 2012.

In December 2007, the FASB issued Statement of Financial Accounting Standard No. 141 (revised 2007), Business Combinations,
(SFAS 141(R)). SFAS 141(R) will change the accounting for acquisitions that close beginning in 2009. More transactions and events will qualify as business combinations and will be accounted for at fair value under the new
standard. SFAS 141(R) promotes greater use of fair values in financial reporting. Some of the changes will introduce more volatility into earnings. SFAS 141(R) is effective for fiscal years beginning on or after December 15, 2008. We
will apply this new standard on any future business combinations.

In December 2007, the FASB issued Statement of Financial Accounting
Standard No. 160, Noncontrolling Interests in Consolidated Financial Statements, (SFAS 160), an amendment of Accounting Research Bulletin No. 51, (ARB No. 51). SFAS 160 will change the
accounting and reporting for minority interests which will be recharacterized as noncontrolling interests and classified as a component of equity. SFAS 160 is effective for fiscal years beginning on or after December 15, 2008.
SFAS 160 requires retroactive adoption of the presentation and disclosure requirements for existing minority interests. There was no financial reporting impact due to this new standard.

In December 2007, the FASB issued EITF Issue 07-1, Accounting for Collaborative Arrangements, (EITF 07-1). Collaborative arrangements
are agreements between parties that participate in some type of joint operating activity. The task force provided indicators to help identify collaborative arrangements and provides for reporting of such arrangements on a gross or net basis pursuant
to guidance in existing authoritative literature. The task force also expanded disclosure requirements about collaborative arrangements. Conclusions within EITF 07-1 are effective for fiscal years beginning December 15, 2008 and are to be
applied retrospectively. We do not expect the application of this standard to have a material impact on our financial position, results of operations and cash flows.

In September 2006, the FASB issued Statement of Financial Accounting Standard No. 157, Fair Value Measurements, which defines fair value, establishes a framework for measuring fair value in accordance with
generally accepted accounting principles, and expands disclosures about fair value measurements. SFAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007. In February 2008, the FASB issued
FSP 157-2, Effective Date of FASB Statement No. 157, which delays the effective date of SFAS 157 for non-financial assets and liabilities to fiscal years beginning after November 15, 2008. The adoption of SFAS 157 related to
financial assets and liabilities did not have a material impact on our Consolidated Financial Statements. We are currently evaluating the impact, if any, that SFAS 157 may have on our future Consolidated Financial Statements related to
non-financial assets and liabilities.

In March 2008, the FASB issued Statement of Financial Accounting Standard No. 161,
Disclosures about Derivative Instruments and Hedging Activities, (SFAS 161), which is intended to improve financial reporting about derivative instruments and hedging activities by requiring enhanced disclosures about the effects
of an entitys derivative instruments and hedging activities on its financial position, financial performance, and cash flows. SFAS 161 is effective for financial statements issued for fiscal years and interim periods beginning after
November 15, 2008, with early application encouraged. We are currently assessing the potential impact that SFAS 161 may have on its financial statements.

|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 and Cash Equivalents and Short-term Investments

We regularly maintain a short and long term investment portfolio of various types of government and corporate debt instruments. We do not directly hold
any asset-backed commercial paper. Our investments are made in accordance with an investment policy approved by our Board of Directors. Maturities of these instruments are less than three 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 available-for-sale and they are carried at fair market value.

Investments in instruments with both fixed and floating rates 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.

Senior Convertible Notes:

At
December 28, 2008, a principal amount of $68.3 million of these Notes remained outstanding and $1.1 million of unamortized debt issue costs were included in Investments and Other Assets. The Notes were originally issued for $225 million in
aggregate principal amount. During 2008, we repurchased $156.7 million principal amount of our senior convertible notes for $138.3 million and expensed $3.2 million of related unamortized debt issue costs and transaction costs resulting in a net
gain of $15.2 million.

Because we pay fixed interest coupons on these Notes, market interest rate fluctuations do not impact our debt
interest payments. However, the fair value of the senior convertible Notes will fluctuate as a result of changes in the price of our common stock, changes in market interest rates and changes in our credit worthiness.

Our 2.25% senior convertible Notes are not listed on any exchange or included in any automated quotation system but are registered for resale under the
Securities Act of 1933.

The Notes rank equal in right of payment with our other unsecured senior indebtedness and mature on
October 15, 2025 unless earlier redeemed by us at our option, or converted or put to us at the option of the holders. Interest is payable semi-annually in arrears on April 15 and October 15 of each year, commencing on April 15,
2006. We may redeem all or a portion of the Notes at par on and after October 20, 2012. The holders may require that we repurchase notes on October 15, 2012, 2015 and 2020 respectively.

Holders may convert the Notes into the right to receive the conversion value (i) when our stock price exceeds 120% of the approximately $8.80 per
share initial conversion price for a specified period, (ii) in certain change in control transactions, and (iii) when the trading price of the Notes does not exceed a minimum price level. For each $1,000 principal amount of Notes, the
conversion value represents the amount equal to 113.6687 shares multiplied by the per share price of our common stock at the time of conversion. If the conversion value exceeds $1,000 per $1,000 in principal of Notes, we will pay $1,000 in cash and
may pay the amount exceeding $1,000 in cash, stock or a combination of cash and stock, at our election.

Foreign Currency

Our sales and corresponding receivables are denominated primarily in U.S. dollars. We generate a significant portion of our revenues from sales to customers located outside 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.

Through our operations in Canada and elsewhere outside the United States, we incur research and development, sales, customer support and administrative expenses in Canadian and other foreign currencies. We are exposed, in the normal course
of business, to foreign currency risks on these expenditures, particularly in Canada. 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 our operating results stemming from our exposure to these risks. As part of this risk management strategy, we enter into foreign exchange forward contracts on behalf of our Canadian subsidiary. These forward contracts offset the impact of
exchange rate fluctuations on forecasted cash flows or firm commitments. We limit the forward contracts operational period to twelve months or less and we do not enter into foreign exchange forward contracts for trading purposes. Because we do not
engage in foreign exchange risk management techniques beyond these periods, our cost structure is subject to long-term changes in foreign exchange rates.

As at December 28, 2008, we had twelve currency forward contracts outstanding that qualified and were designated as cash flow hedges. The U.S. dollar notional amount of these contracts was $43.6 million and the
contracts had a fair value of ($4.6) million.

We attempt to limit our exposure to foreign exchange rate fluctuations from our Canadian
dollar net asset or liability positions. A 5% shift in the foreign exchange rates between U.S. dollar and the Canadian dollar would impact pre-tax net income by approximately $1.2 million.

Other Investments

Our other
investments include strategic investments in privately held companies that are carried on our balance sheet at cost, net of write-downs for non-temporary declines in market value. 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. 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 has been impaired. For example, in
the second quarter of 2006 we recorded a charge of $3.2 million for impairment of an investment in a private company. We may record additional impairment charges should we determine that our investments have incurred a non-temporary decline in
value.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of PMC-Sierra, Inc.

We have audited the accompanying consolidated balance sheets of PMC-Sierra, Inc. and subsidiaries (the Company) as of December 28, 2008 and December 30, 2007, and the related consolidated statements of operations, cash
flows, and stockholders equity for each of the three years in the period ended December 28, 2008. Our audits also included the financial statement schedules listed in the Index at Item 15(a). These consolidated financial statements
and financial statement schedules are the responsibility of the Companys management. Our responsibility is to express an opinion on the consolidated financial statements and financial statement schedules based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). 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 financial position of
PMC-Sierra, Inc. and subsidiaries as of December 28, 2008 and December 30, 2007, and the results of their operations and their cash flows for each of the three years in the period ended December 28, 2008, in conformity with accounting
principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedules, when considered in relation to the basic consolidated financial statements taken as a whole, present fairly, in all material
respects, the information set forth therein.

As discussed in Note 1 to the consolidated financial statements, the Company adopted
Statement of Financial Accounting Standard No.157, Fair Value Measurements, effective January 1, 2008.

We have also audited,
in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Companys internal control over financial reporting as of December 28, 2008, based on the criteria established in Internal
ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 25, 2009 expressed an unqualified opinion on the Companys internal control over financial
reporting.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 28, 2008

NOTE 1. Summary of Significant
Accounting Policies

Description of business.PMC-Sierra, Inc (the Company or PMC) designs, develops, markets
and supports semiconductor solutions for the Enterprise Networking, Wide Area Network Infrastructure, and Access Network markets. The Company offers worldwide technical and sales support through a network of offices in North America, Europe and
Asia.

Basis of presentation.The accompanying Consolidated Financial Statements have been prepared pursuant to the rules and
regulations of the United States Securities and Exchange Commission (SEC) and United States Generally Accepted Accounting Principles (GAAP). Fiscal 2008 consisted of 52 weeks and ended on Sunday, December 28. Fiscal 2007
consisted of 52 weeks and ended on Sunday, December 30. Fiscal 2006 consisted of 52 weeks and ended on Sunday, December 31. The Companys reporting currency is the U.S. dollar. The accompanying Consolidated Financial Statements
include the accounts of PMC-Sierra, Inc. and any of its subsidiaries or investees in which PMC exercises control. As at December 28, 2008 and December 30, 2007, all subsidiaries included in these Consolidated Financial Statements were
wholly owned by PMC. All inter-company accounts and transactions have been eliminated.

Estimates. The preparation of financial
statements and related disclosures in conformity with GAAP 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,
stock-based compensation, purchase accounting assumptions including those used to calculate the fair value of intangible assets and goodwill, the valuation of investments, accounting for doubtful accounts, inventory reserves, depreciation and
amortization, asset impairments, sales returns, warranty costs, income taxes including uncertain tax positions, restructuring costs, and contingencies. Actual results could differ from these estimates.

Cash and cash equivalents, short-term investments and investment securities. At December 28, 2008, cash and cash equivalents included $0.8
million (2007$0.8 million) pledged with a bank as collateral for letters of credit issued as security for leased facilities. Cash equivalents are defined as highly liquid interest-earning instruments with maturities at the date of purchase of
three months or less. Short-term investments are investments with original maturities greater than three months, but less than one year. Investments with maturities beyond one year are classified as long-term investment securities.

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

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.

In 2008, the Company decreased inventory reserves by $3.1 million (2007$1.5 million,
2006$2.3 million) for inventory that was scrapped during the year.

Investments in private entities. The Company has
investments in privately traded companies 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 Investments and other assets on the Companys Consolidated Balance Sheet and are carried at cost, net of write-downs for impairment.

Investments in public companies.In 2005, the Company had an investment in a publicly traded company in which it had less than 20% of the voting
rights and in which it did not exercise significant influence. These securities were 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 as a separate component of stockholders equity. The Company sold this investment in 2006 (see Note 8. Investments and Other Assets).

Deposits for wafer fabrication capacity. The Company has wafer supply agreements with two independent foundries. Under these agreements, the Company has deposits of $5.1 million (2007$5.1 million) to secure access to wafer
fabrication capacity. During 2008, the Company purchased $48.3 million ($43.3 million and $42.0 million in 2007 and 2006, 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. In 2008, PMC renewed its supply agreements through
December 2009 with its two main foundries with no changes in terms. No deposit refunds were received in 2008 and 2007.

Property and
equipment, net. Property and equipment is stated at cost, net of write-downs for impairment, and accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets, ranging from two
to five years. Leasehold improvements are capitalized and amortized over the shorter of their estimated useful lives or the lease term.

The components of property and equipment, net are as follows:

Goodwill. Goodwill is recorded when the purchase price paid for an acquisition exceeds the
estimated fair value of the net identified tangible and intangible assets acquired. The Company performs a two-step process on an annual basis, or more frequently if necessary, to determine 1) whether the fair value of the relevant reporting unit
exceeds the carrying value and 2) the amount of an impairment loss, if any. The Company completed this process in December 2008, 2007 and 2006, and determined that there was no impairment to goodwill.

Intangible assets, net. Intangible assets, net, consist of intangible assets acquired through business combinations (See Note 2. Business
Combinations), which are amortized over their estimated useful lives ranging from four to ten years or have indefinite lives, and purchased developed technology assets that are amortized over their economic lives, which are normally three years. The
components of intangible assets, net are as follows:

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

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



|                                  |  |                  |        |                  |   |

Foreign currency translation. For all foreign operations, the U.S. dollar is used as the
functional currency. Monetary assets and liabilities in foreign currencies are translated into U.S. dollars using the exchange rate as of 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 reported separately as Foreign exchange gain (loss) under Other income (expense) on the Consolidated Statements of Operations.

Derivatives and Hedging Activities. Fluctuating foreign exchange rates may significantly impact PMCs net income and cash flows. The Company
periodically hedges forecasted foreign currency transactions related to certain operating expenses. All derivatives are recorded in the balance sheet at fair value. For a derivative designated as a fair value hedge, changes in the fair value of the
derivative and of the hedged item attributable to the hedged risk are recognized in net income (loss). For a derivative designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are recorded in other
comprehensive income and are recognized in net income (loss) when the hedged item affects net (loss) income. Ineffective portions of changes in the fair value of cash flow hedges are recognized in net income (loss). If the derivative used in an
economic hedging relationship is not designated in an accounting hedging relationship or if it becomes ineffective, changes in the fair value of the derivative are recognized in net income (loss). During the year ended December 28, 2008, all
hedges were designated as cash flow hedges.

Fair value of financial instruments. The estimated fair value of financial instruments
has been determined by the Company using available market information and appropriate valuation methodologies as prescribed under Statement of Financial Accounting Standards No. 157, Fair Value Measurements, (SFAS 157).
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 use of different market assumptions and/or estimation methodologies could have a significant effect on the estimated
fair value amounts. The fair value of the Companys short-term investments, investment securities, derivative instruments are estimated using available market information and appropriate valuation. The fair value of investments in public
companies is determined using quoted market prices for those securities. The fair value of investments in private entities is not readily determinable due to the illiquid market for these investments. The fair value of the deposits for wafer
fabrication capacity is not readily determinable because the timing of the related future cash flows is not determinable and there is no market for the sale of these deposits (see Note 4. Fair Value Measurements).

The carrying values of cash equivalents, accounts receivable and accounts payable approximate fair value
because of their short maturities.

Our 2.25% senior convertible notes are not listed on any securities exchange or included in any
automated quotation system, but have been traded over the counter, on the Portal Market or under Rule 144 of the Securities Act of 1933. The exchange prices from these trades are not always available to us and may not be reliable. Trades under the
Portal Market do not reflect all trades of the securities and the figures recorded are not independently verified. The Company has incorporated independent market quotes in estimating the fair value of the debt to be $50.9 million, or $74.50
per $100 face value as of December 28, 2008.

As of and for the year ended December 28, 2008, the use of derivative financial
instruments was not material to the results of operations or our financial position (see Derivatives and Hedging Activities in this Note).

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

At December 28, 2008, there were two distributors that accounted for 14%
and 11% of accounts receivables and three other customers that each accounted for 11%, 11% and 10% of accounts receivables, respectively. At December 30, 2007, appropriately 24% of accounts receivables 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 periods and the geographical dispersion of the Companys sales. The Company generally does not require collateral security for outstanding amounts.

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

Revenue recognition. The Company recognizes product revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales
price is fixed or determinable, and collectibility is reasonably assured. PMC generates revenues from direct sales, sales to distributors and sales of consignment inventory. The Company recognizes revenues on goods shipped directly to customers at
the time of shipping as that is when title passes to the customer and all revenue recognition criteria specified above are met.

PMC has a
two-tier distribution network, distinguishing between major and minor distributors. The Company currently has one major distributor for which it recognizes revenue on a sell-through basis, utilizing information provided by the distributor. This
distributor maintains significantly higher levels of inventory than minor distributors and is given business terms to return a portion of inventory and receive credits for changes in selling prices to end customers, the magnitude of which is not
known at the time goods are shipped to this distributor. PMC personnel are often involved in the sales from this distributor to end customers and the Company may utilize inventory at the major distributor to satisfy product demand by other
customers.

PMC recognizes revenues from minor distributors at the time of shipment. These distributors are also given business terms to
return a portion of inventory and receive credits for changes in selling prices to end customers. At the time of shipment, product prices are fixed and determinable and the amount of future returns and pricing allowances to be granted in the future
can be reasonably estimated and accrued.

The Company has consignment inventory which is held at the customers premises. PMC
recognizes revenue on these goods when the customer uses them in production, as that is when title passes to the customer. These sales from consignment inventory are subject to the same warranty terms that are applied to direct sales.

PMC product sales are subject to warranty claims against regular mechanical or electrical failure. PMC maintains accruals for potential returns based on
its historical experience.

Research and development expenses. The Company expenses research and development
(R&D) costs as incurred. R&D costs include payroll and related costs, materials, services and design tools used in product development, depreciation, and other overhead costs including facilities and computer equipment costs.
Intellectual property (IP) purchased from third parties is capitalized and amortized over the expected useful life of the IP. For the years ended December 28, 2008, December 30, 2007 and December 31, 2006, research
and development expenses were $157.6 million, $159.1 million and $158.7 million.

Product warranties. The Company provides a limited
warranty on most of its standard products and accrues for the expected cost at the time of shipment. The Company estimates its warranty costs based on historical failure rates and related repair or replacement costs. The following table summarizes
the activity related to the product warranty liability during fiscal 2008, 2007 and 2006:

Other Indemnifications. From time to time, on a limited basis, the Company indemnifies
customers, as well as suppliers, contractors, lessors, and others with whom it has contracts, against combinations of loss, expense, or liability arising from various triggering events related to the sale and use of Company products, the use of
their goods and services, the use of facilities, the state of assets that we sell and other matters covered by such contracts, normally up to a specified maximum amount. The Company evaluates estimated losses for such indemnifications under
Statement of Financial Accounting Standard No. 5, Accounting for Contingencies, as interpreted by Financial Accounting Standard Board (FASB) Interpretation No. 45, Guarantors Accounting and Disclosure
Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others. The Company has no history of indemnification claims for such obligations and has not accrued any liabilities related to such indemnifications in the
Consolidated Financial Statements.

Stock-based compensation. The Company accounts for all share-based payment awards under
Statement of Financial Accounting Standard No. 123 (revised 2004), Share-Based Payment, (SFAS 123(R)). SFAS 123(R) requires the Company to measure the cost of services received in exchange for an award of equity instruments
based on the grant-date fair value of the award. The cost of such award will be recognized over the period during which services are provided in exchange for the award, generally the vesting period. The Company adopted SFAS 123(R) using the modified
prospective transition method and therefore prior period results have not been restated.

The Company applies the principles of the SEC
issued Staff Accounting Bulletin No. 107 (SAB 107) in connection with SFAS 123(R), which requires all share-based payments to employees, to be recognized in the financial statements based upon their respective grant-date fair
values.

During 2008, the Company recognized $24.8 million in stock-based compensation expense or $0.06 per share. No domestic tax benefits
were attributed to the tax timing differences arising from stock-based compensation expense because a full valuation allowance was maintained for all domestic deferred tax assets.

See Note 5. Stock-Based Compensation.

Income taxes. Income taxes are reported under Statement of Financial Accounting Standard
No. 109, Accounting for Income Taxes, (SFAS 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.

On
July 13, 2006, the FASB issued Interpretation No. 48, Accounting for Uncertainty in Income TaxesAn Interpretation of FASB Statement No. 109, (FIN 48). FIN 48 clarifies the accounting for uncertainty in income
taxes recognized in an entitys financial statements in accordance with SFAS 109, and prescribes a recognition threshold and measurement attributes for financial statement disclosure of tax positions taken or expected to be taken on a
tax return. Under FIN 48, the impact of an uncertain income tax position on the income tax return must be recognized at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income
tax position will not be recognized if it has less than a 50% likelihood of being sustained. Additionally, FIN 48 provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.
FIN 48 is effective for fiscal years beginning after December 15, 2006.

The Company adopted the provisions of FIN 48 on
January 1, 2007. As a result of the implementation of FIN 48, the Company recognized a $4.7 million net decrease in the liability for unrecognized tax benefits which was accounted for as a reduction to the retained deficit. Included in this
opening adjustment was a $6.9 million increase in the liability for unrecognized tax benefits relating to additional uncertain tax positions the Company identified as existing at December 31, 2006. In addition, the Company recognizes interest
and penalties related to income tax liabilities as a component of income tax expense.

Further, as part of the implementation of FIN 48,
the Company reclassified $57 million from current income taxes payable to current liability for unrecognized tax benefit and $42 million from long term income taxes payable to long term liability for unrecognized tax benefit. In addition, the
Company reclassified $27.5 million of tax benefits to the deferred tax asset account with a corresponding increase to the unrecognized tax benefit account.

Included in the balance of unrecognized tax benefits at January 1, 2007, are $125 million of tax benefits. See Note 15. Income taxes.

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, shares issuable on our Employee Share Purchase Plan and common shares issuable on conversion of the Companys senior convertible notes.

Segment reporting. Segmented information is reported in accordance with Statement of Financial
Accounting Standards No. 131, Disclosures about Segments of an Enterprise and Related Information, (SFAS 131). 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. In all periods presented, the Company operated in one reportable segment: networking products.

Recent Accounting Pronouncements.

In
May 2008, the FASB issued Staff Position Accounting Principles Board Opinion 14-1, Accounting for Convertible Debt Instruments That May Be Settled in Cash Upon Conversion (Including Partial Cash Settlements, (APB 14-1), which
will change the accounting treatment for convertible securities which the issuer may settle fully or partially in cash. Under APB 14-1, cash settled convertible securities will be separated into their debt and equity components. The value assigned
to the debt component will be the estimated fair value, as of the issuance date, of a similar debt instrument without the conversion feature, and the difference between the proceeds for the convertible debt and the amount reflected as debt, will be
recorded as equity. As a result, the debt component will be recorded at a discount from its face value, reflecting its below market coupon interest rate. The debt will subsequently be accreted to its face value over its expected term, with the
accretion being reflected as additional interest expense in the statement of operations. APB 14-1 is required to be adopted retrospectively, at the beginning of the Companys 2009 fiscal year, in respect of convertible securities
outstanding at the end of the Companys 2008 fiscal year.

The Companys senior convertible notes (Notes) with a face
value of $225 million were issued in October 2005 and bear interest at a rate of 2.25% per annum. At the date of issuance, the Companys borrowing rate for similar debt instruments without any equity conversion features was estimated to be
8.0% per annum. Under APB 14-1, at the issuance date, the debt and equity components would be $155.6 million and $69.4 million, respectively, before considering related issuance costs. The following table shows the effect of this new
standard on the Consolidated Financial Statements, had it been applied since the issuance date of the Companys Notes, and takes into account the Companys repurchases of a portion of these Notes to December 28, 2008:

Based on the Notes outstanding as at December 28, 2008, additional interest expense arising from the adoption of APB 14-1 is expected to be
approximately $3 million annually. The debt discount is being accreted over the term to the earliest date at which the holders of the Notes may exercise redemption rights, which is October 15, 2012 (see Note 10. Long-term debt).

In December 2007, the FASB issued Statement of Financial Accounting Standard No. 141 (revised 2007), Business Combinations,
(SFAS 141(R)). SFAS 141(R) will change the accounting for acquisitions that close beginning in 2009. More transactions and events will qualify as business combinations and will be accounted for at fair value under the new
standard. SFAS 141(R) promotes greater use of fair values in financial reporting. Some of the changes will introduce more volatility into earnings. SFAS 141(R) is effective for fiscal years beginning on or after December 15, 2008. The
Company will apply this new standard on any future business combinations.

In December 2007, the FASB issued Statement of Financial
Accounting Standard No. 160, Noncontrolling Interests in Consolidated Financial Statements, (SFAS 160), an amendment of Accounting Research Bulletin (ARB) No. 51. SFAS 160 will change the accounting
and reporting for minority interests which will be recharacterized as noncontrolling interests and classified as a component of equity. SFAS 160 is effective for fiscal years beginning on or after December 15, 2008. SFAS 160 requires
retroactive adoption of the presentation and disclosure requirements for existing minority interests. There was no financial reporting impact due to this new standard.

In December 2007, the FASB issued EITF Issue 07-1, Accounting for Collaborative Arrangements, (EITF 07-1). Collaborative arrangements are agreements between parties that participate in some
type of joint operating activity. The task force provided indicators to help identify collaborative arrangements and provides for reporting of such arrangements on a gross or net basis pursuant to guidance in existing authoritative literature. The
task force also expanded disclosure requirements about collaborative arrangements. Conclusions within EITF 07-1 are effective for fiscal years beginning December 15, 2008 and are to be applied retrospectively. The Company does not expect the
application of this standard to have a material impact on its financial position, results of operations and cash flows, as it does not have any collaborative arrangements.

In September 2006, the FASB issued Statement of Financial Accounting Standard No. 157, Fair Value Measurements, (SFAS 157), which
defines fair value, establishes a framework for measuring fair value in accordance with GAAP, and expands disclosures about fair value measurements. SFAS 157 is effective for financial statements issued for fiscal years beginning after
November 15, 2007. In February 2008, the FASB issued FSP 157-2, Effective Date of FASB Statement No. 157, which delays the effective date of SFAS 157 for non-financial assets and liabilities to fiscal years beginning after
November 15, 2008. The adoption of SFAS 157 related to financial assets and liabilities did not have a material impact on the Consolidated Financial Statements. The Company is currently evaluating the impact, if any, that SFAS 157 may
have on its future Consolidated Financial Statements related to non-financial assets and liabilities.

In March 2008, the Statement of
Financial Accounting Standard No. 161, Disclosures about Derivative Instruments and Hedging Activities, (SFAS 161), which is intended to improve financial reporting about derivative instruments and hedging activities by
requiring enhanced disclosures about the effects of an entitys derivative instruments and hedging activities on its financial position, financial performance, and cash flows. SFAS 161 is effective for financial statements issued for fiscal
years and interim periods beginning after November 15, 2008, with early application encouraged. The Company is currently assessing the potential impact that SFAS 161 may have on its financial statements.

NOTE 2. Business Combinations

Storage Semiconductor Business

On February 28, 2006, the Company completed the acquisition of the former storage
semiconductor business of Agilent Technologies, Inc. (the Storage Semiconductor Business) pursuant to the terms of the Purchase and Sale Agreement dated October 28, 2005 (the Purchase Agreement) between PMC and Avago
Technologies Pte. Limited (Avago). These financial statements include the results of operations of the acquired business from the acquisition date.

PMC purchased the Storage Semiconductor Business due to its strategic and product fit with PMC, the market position the Storage Semiconductor Business has in the Fibre Channel controller market, the design
capabilities of its engineering team, and the growth opportunities for standard semiconductor solutions in the enterprise storage market. The Storage Semiconductor Business was part of Agilent's Semiconductor Products Group (as defined in the
Purchase Agreement), which Avago, an entity created by Kohlberg Kravis Roberts & Co. and Silver Lake Partners, acquired in December 2005. Under the terms of the Purchase Agreement, Palau Acquisition Corporation, a Delaware corporation and
direct wholly owned subsidiary of PMC purchased the Storage Semiconductor Business for the following consideration:

|                                             |  |   |        

Merger costs include investment banking, legal and accounting fees, and other external costs
directly related to the acquisition.

The total purchase price has been allocated to the fair value of assets acquired and liabilities
assumed, and the excess of the purchase price over the net assets acquired was recorded as goodwill, which for this acquisition is deductible for tax purposes. The allocation was determined by management based on a third-party valuation. Subsequent
to the acquisition date, the initial purchase price and residual goodwill were adjusted by $1.1 million for additional inventory, by $4 million for design software licenses, and by $1.9 million for settlement of a legal matter. The allocation of the
purchase price was as follows:

The amount allocated to in-process research and development (IPR&D) represented an
estimate of the fair value of research projects that had not reached technological feasibility and had no alternative future use. The estimated fair value of IPR&D was expensed immediately following the consummation of the acquisition.

PMC acquired three next-generation Tachyon storage protocol IPR&D projects related to the Storage Semiconductor Business. One of the
projects is a multi-protocol storage controller which was in the early stage of development, one of the next-generation Tachyon projects was also in the early stage of development and two projects were next-generation Tachyon projects in later
stages of development. The value assigned to IPR&D was calculated using the income approach by determining cash flow projections related to the identified projects. The assumptions included information on revenues from existing products and
future expected trends for each technology, with an estimated useful life of five to nine years. The rates used to discount the net cash flows to their present values were based upon a weighted average cost of capital of 19%. The discount rate was
determined after consideration of market rates of return on debt and equity capital and the risk associated with achieving forecasted sales related to the assets acquired.

The fair value was as follows:

Passave Inc.

On May 4, 2006, the Company acquired Passave, Inc. (Passave), a privately held Delaware corporation, pursuant to the Agreement and Plan of Merger (the Merger Agreement), dated April 4, 2006, among the
Company, a newly formed direct wholly-owned subsidiary of the Company (Merger Sub), Passave, and a representative of certain securityholders of Passave. Under the terms of the Merger Agreement, the Company issued shares of its common
stock and assumed stock options, and incurred merger costs having a total value of $304 million for all of the outstanding capital stock, warrants and outstanding stock options of Passave. Of this amount, $257.5 million was allocated to the purchase
price, and $46.5 million related to unvested stock and stock options of Passave which will be recorded as stock-based compensation over the requisite service period in accordance with FAS 123R. The fair value of options assumed was calculated using
a lattice-binomial method. The Company and the security holders of Passave have each agreed to indemnify the other for, among other things, breaches of representations, warranties and covenants of the Company and Passave in the Merger Agreement.
These Consolidated Financial Statements include the results of operations of Passave from the acquisition date.

The amount allocated to IPR&D represented an estimate of the fair value of research projects
that had not reached technological feasibility and had no alternative future use. The estimated fair value of IPR&D was expensed immediately following the consummation of the acquisition.

PMC acquired the following IPR&D projects from Passave:

EPON and AFE productsprovide further enhancements and functionality to the EPON series

GPON
productsprovide further enhancements and functionality to the GPON series

The value assigned to IPR&D was calculated using the
income approach by determining cash flow projections related to identified projects. The assumptions included information on revenues from existing products and future expected trends for each technology, with an estimated useful life of 6 years.

completion of each project was estimated to determine the discount rates to be applied to the valuation of the in-process technology. Based upon the level of
completion and the risk associated with in-process technology, we applied discount rates that ranged from 20%23% to value the projects acquired.

The fair value for each project is as follows:

Goodwill represents the excess of the purchase price over the fair value of the net tangible and
intangible assets acquired. In accordance with Statement of Financial Accounting Standard No. 142, Goodwill and Other Intangible Assets, goodwill will not be amortized but will instead be tested for impairment annually or more frequently
if certain indicators are present.

The pro forma financial information presented below gives effect to the acquisitions of Passave and the
Storage Semiconductor Business as if both acquisitions had occurred as of the beginning of each fiscal year presented below. If the acquisitions had occurred at the beginning of 2005, the $35.3 million charge for in-process research and
development and acquisition-related costs would have been expensed in 2005. Amortization of intangible assets would have been higher by $43.3 million, and $6.0 million, in 2005 and 2006, respectively. In addition, stock-based compensation would have
been higher by $17.4 million and $3.9 million in 2005 and 2006, respectively, due to amortization of expense associated with unvested options assumed with exercise prices below fair market value on the acquisition date.

The pro forma results do not purport to represent what the Companys results of operations actually would have been if the transactions had occurred
on the date indicated or what the results of operations will be in future periods.

NOTE 3. Derivative Instruments

The Company generates revenues in U.S. dollars but incurs a portion of its operating expenses in various foreign currencies, primarily the Canadian dollar. To minimize the short-term impact of foreign currency
fluctuations on the Companys operating expenses, the Company uses currency forward contracts.

Currency forward contracts that are
used to hedge exposures to variability in forecasted foreign currency cash flows are designated as cash flow hedges. The maturities of these instruments are less than twelve months. For these derivatives, the gain or loss from the effective portion
of the hedge is initially reported as a component of other comprehensive income in stockholders equity and subsequently reclassified to earnings in the same period in which the hedged transaction affects earnings. The gain or loss from the
ineffective portion of the hedge is recognized as interest income or expense immediately.

At December 28, 2008, the Company had
twelve currency forward contracts outstanding that qualified and were designated as cash flow hedges. The U.S. dollar notional amount of these contracts was $43.6 million and the contracts had a fair value of $4.6 million loss. No portion of the
hedging instruments gain or loss was

excluded from the assessment of effectiveness. The ineffective portions of hedges had no significant impact on earnings, nor are they expected to over the
next twelve months.

NOTE 4. Fair Value Measurements

On January 1, 2008, the Company adopted SFAS 157, which defines fair value, establishes guidelines for measuring fair value and expands disclosures on fair value measurements. In February 2008, the FASB issued FSP 157-2, that deferred
the effective date of SFAS 157 for one year for non-financial assets and liabilities recorded at fair value on a non-recurring basis. SFAS 157 defines fair value as the exchange price that would be received for an asset or paid to transfer a
liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. SFAS 157 also specifies a hierarchy of valuation techniques which
requires an entity to maximize the use of observable inputs that may be used to measure fair value:

Level 1Quoted prices in active
markets are available for identical assets and liabilities. The Companys Level 1 assets include cash equivalents, which are generally acquired or sold at par value and are actively traded.

Level 2Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; or other inputs that are observable or
can be corroborated by observable market data for substantially the full term of the assets or liabilities. The Companys Level 2 liabilities include forward currency contracts whose value is determined using a pricing model with inputs that
are observable in the market or corroborated with observable market data.

Level 3Pricing inputs include significant inputs that are
generally not observable in the marketplace. These inputs may be used with internally developed methodologies that result in managements best estimate of fair value. At each balance sheet date, the Company performs an analysis of all
instruments subject to SFAS 157 and would include in Level 3 all of those whose fair value is based on significant unobservable inputs. The Companys Level 3 assets include investments in money market funds classified in short-term investments
(see Note 7. Investment securities).

Financial assets and liabilities measured on a recurring basis as of December 28, 2008 are
summarized below:

NOTE 5. Stock-Based Compensation

At December 28, 2008, the Company has two stock-based compensation programs, which are described below. None of the Companys stock-based awards are classified as liabilities. The Company did not capitalize
any stock-based compensation cost, and recorded compensation expense as follows:

The Company received cash of $16.6 million from the exercise of stock-based awards during 2008.
The total intrinsic value of stock awards exercised during 2008 was $13.1 million.

As of December 28, 2008, there was $27.0 million of
total unrecognized compensation cost related to nonvested stock options granted under the Companys stock option plans, which is expected to be recognized over a period of 2.6 years. As of December 28, 2008, there was $8.4 million of total
unrecognized compensation cost related to nonvested Restricted Stock Units (RSUs) awarded under the Companys stock option plans, which is expected to be recognized over a period of 3.1 years.

The fair value of the Companys stock option awards granted to employees during 2008 was estimated using a lattice-binomial valuation model. Prior
to the second quarter of 2005, the fair value of the Companys stock option awards to employees was estimated, for disclosure purposes under Statement of Financial Accounting Standard No. 123, Accounting for stock-based compensation
(SFAS 123), using a Black-Scholes option pricing model which was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. The Company believes that the
lattice-binomial model provides a better estimate of the fair value of stock option awards because it considers the contractual term of the option, the probability that the option will be exercised prior to the end of its contractual life, and the
probability of termination or retirement of the option holder in computing the value of the option. Both models require the input of highly subjective assumptions including the expected stock price volatility and expected life.

The Companys estimates of expected volatilities are based on a weighted historical and market-based implied volatility. The Company uses historical
data to estimate option exercises and employee terminations within the valuation model. Separate groups of employees that have similar historical exercise behavior are considered separately for valuation purposes. The expected term of options
granted is derived from the output of the stock option valuation model and represents the period of time that granted options are expected to be outstanding. The risk-free rate for periods within the contractual life of the stock option is based on
the U.S. Treasury yield curve in effect at the time of the grant.

The fair values of the Companys stock option and Employee Stock
Purchase Plan, (ESPP) awards were estimated using the following weighted average assumptions:

Stock Option Plans

The Company issues its common stock under the provisions of various stock option plans. Stock option awards are granted with an exercise price equal to the closing market price of the Companys common stock at
the grant date. The options generally expire within five to ten years and vest over four years.

In 2001, the Company simplified its plan
structure. The 2001 Stock Option Plan (the 2001 Plan) was created to replace a number of stock option plans the Company had assumed in connection with mergers and acquisitions completed prior to 2001. The number of shares available for
issuance under the 1994 Incentive Stock Plan (1994 Plan) were approved by stockholders. New stock options or other equity incentives may only be issued under the 1994 Plan and the 2001 Plan. In the second quarter of 2006, the Company
assumed the stock option plans and all outstanding stock options of Passave as part of the merger consideration. (See Note. 2 Business Combinations)

Activity under the option plans during the year ended December 28, 2008 was as follows:

Employee Stock Purchase Plan

In 1991, the Company adopted an ESPP under Section 423 of the Internal Revenue Code. The ESPP allows eligible participants to purchase shares of the Companys common stock through payroll deductions at a purchase price of 85% of
the lower of the fair market value of the Companys stock on the close of the first trading day or last trading day of the six-month purchase period. Under the ESPP, the number of shares authorized to be available for issuance under the plan
are increased automatically on January 1 of each year until the expiration of the plan. The increase will be limited to the lesser of (i) 1% of the outstanding shares on January 1 of each year, (ii) 2,000,000 shares (after
adjusting for stock dividends), or (iii) an amount to be determined by the Board of Directors.

During 2008, 1,865,784 shares were
issued under the Plan at a weighted-average price of $3.92 per share. As of December 28, 2008, 8,284,156 shares were available for future issuance under the ESPP (20078,149,940).

The weighted-average estimated fair values of Employee Stock Purchase Plan awards during 2008, 2007, and 2006, were $0.53, $2.59 and $3.27 per share,
respectively.

2007

In the first quarter of 2007, the Company initiated a cost-reduction plan that involved staff reductions of 175 employees at various sites and the closure of design centers in Saskatoon, Saskatchewan and Winnipeg, Manitoba. The Company also
vacated excess office space at its Santa Clara facility. PMC continued to rationalize costs in the fourth quarter of 2007 by reducing headcount by 18 employees primarily at the Burnaby facility.

In 2008, the Company recorded a net reduction of its accrual for excess facilities by $0.2 million, as the Company fulfilled a portion of these
obligations, and made payments of $0.9 million related to the 2007 plan. To date, the Company has incurred $10.3 million in termination and relocation costs, $2.6 million for excess facilities and contract termination costs, and $2.5 million in
asset impairment charges.

##### Table of Contents

The Company has made payments of $12.1 million in connection with this plan. As of December 28,
2008, $7 thousand in severance costs remained to be paid and payments related to the excess facilities may extend until 2011.

The
Company initially expected to save approximately $16 million in payroll-related costs on an annualized basis. The Company achieved its prorated portion of these expected cost savings in 2007. The Company continued to contain costs in accordance with
its 2007 restructuring plan, however, it also initiated new R&D programs in 2008 which resulted in increases in payroll-related costs of approximately $4.9 million that partially offset the cost savings anticipated by the 2007 restructuring
plan.

2006

In the third quarter of 2006, the
Company closed its Ottawa development site in order to reduce operating expenses and the space was vacated by the end of the fourth quarter of 2006. Approximately 35 positions were eliminated, primarily from research and development, resulting in
one-time termination benefit and relocation costs of $2.2 million, and $2.0 million for excess facilities. The Company also eliminated 10 positions from research and development in the Companys Portland development site, resulting in
restructuring charges of $1.4 million, comprised of $0.8 million in severance, $0.3 million for excess facilities, $0.1 million for contract termination and $0.2 million in asset impairment.

In 2008, the Company recorded a net addition of its accrual for excess facilities by $0.1 million, as the original assumptions regarding possible
sublease of the exited facilities were not realized, and made payments of $0.5 million related to the 2006 plan.

To date, the Company has
made payments relating to these activities of $4.4 million. As of December 28, 2008, all severance costs have been paid. Payments related to the excess facilities will extend to 2010.

2005

During 2005, the Company completed various
restructuring activities aimed at streamlining production and reducing operating expenses. In the first quarter of 2005, the Company recorded restructuring charges of $0.9 million in severance costs related to the termination of 24 employees across
all business functions. In the second quarter of 2005, the Company expanded the workforce reduction activities initiated during the first quarter and terminated 63 employees from research and development located in the Santa Clara facility. In
addition, the Company consolidated two manufacturing facilities (Santa Clara, California and Burnaby, British Columbia) into one facility (Burnaby), which involved the termination of 26 employees from production control, quality assurance, and
product engineering. As a result, the Company recorded total second quarter restructuring charges of $7.6 million, including $6.7 million for termination benefits and a $0.9 million write-down of equipment and software assets whose value was
impaired as a result of these plans. In the third quarter of 2005, the Company consolidated its facilities and vacated excess office space in the Santa Clara location, and recorded a restructuring charge of $5.3 million for excess facilities and an
additional $0.1 million in severance costs.

In the first quarter of 2006, the Company continued the workforce reduction plans initiated in
2005 and recorded $1.6 million in restructuring charges related to the termination of 19 employees, primarily from research and development, in the Santa Clara facility. During the third quarter of 2006, the Company reduced its estimated severance
accrual related to the 2005 workforce reduction activities by $0.4 million, and increased the accrual for excess facilities related to the 2005 restructuring by $0.8 million. The Company further increased its accrual for excess facilities by $0.5
million in the fourth quarter of 2007. In 2008, the Company recorded an additional accrual for excess facilities of $1.1 million, as the original assumptions regarding possible sublease of the exited facilities were not realized, and made payments
of $1.4 million related to the 2005 plan.

To date, the Company has made payments relating to these activities of $13.4 million. As of
December 28, 2008, all severance costs have been paid. Payments related to the excess facilities will extend to 2011.

2003 and 2001

In 2003 and 2001, the Company implemented three restructuring plans aimed at focusing development efforts on key projects and reducing operating costs in response to the severe and prolonged economic downturn in the semiconductor industry.
PMCs assessment of the market demand for its products, and the development efforts necessary to meet this demand, were key factors in the decisions to implement these restructuring plans. As end markets for the Companys products had
contracted, certain projects were curtailed in an effort to cut costs. Cost reductions in all other functional areas were also implemented, as fewer resources were required to support the reduced level of development and sales activities during
these periods.

The January 2003 restructuring included the termination of 175 employees and the closure of design centers in Maryland,
Ireland and India, and vacating office space in the Santa Clara facility. To date, PMC has recorded restructuring charges of $18.3 million in accordance with Statement of Financial Accounting Standard No. 146, Accounting for Costs Associated
with Exit or Disposal Activities, including $1.5 million for asset write-downs. These charges related to workforce reduction, lease and contract settlement costs, and the write-down of certain property, equipment and software assets whose value
was impaired as a result of this restructuring plan. PMC has disposed of the property improvements and computer equipment, and software licenses have been cancelled or are no longer being used. In 2006, the Company reversed $2.3 million of this
restructuring accrual because certain floors in the Santa Clara facility that had been vacated in 2003 were re-occupied in 2006 due to the addition of personnel that occurred with the acquisition of the Storage Semiconductor Business. The Company
reversed a further $0.5 million in 2007, as it completed a portion of the lease obligation at this site.

The October 2001 restructuring
plan included the termination of 341 employees, the consolidation of excess facilities, and the curtailment of certain research and development projects, resulting in a restructuring charge of $175.3 million, including $12.2 million of asset
write-downs. Due to the continued downturn in real estate markets, the Company recorded additional provisions for abandoned office facilities of $1.3 million in the fourth quarter of 2004.

In the first quarter of 2001, PMC recorded a charge of $19.9 million for a restructuring plan that included the termination of 223 employees across all
business functions, the consolidation of a number of facilities and the curtailment of certain research and development projects. Due to the continued downturn in real estate markets, the Company recorded additional provisions for abandoned office
facilities of $2.2 million in the fourth quarter of 2004, $0.8 million in the third quarter of 2006, and $0.9 million in the fourth quarter of 2007. In 2008, the Company recorded a net reduction of its accrual for excess facilities of $0.7 million,
as the Company fulfilled a portion of these obligations, and made payments of $1.3 million related to the 2001 plan.

To date, PMC has made
cash payments of $12.7 million and $178.0 million related to the 2003 and 2001 plans, respectively. The Company has completed the activities contemplated in these restructuring plans, but has not yet terminated the leases on all of its surplus
facilities. Efforts to exit these sites are ongoing, but the payments related to these facilities could extend to 2011.

NOTE 7. Investment securities

At December 28, 2008, the Company had investments in money market funds of $278.9 million (2007$323.8 million), comprised of
bank notes, commercial paper, certificates of deposit and floating rate notes.

The short-term investments of $209.7 million held at
December 28, 2008 relate to shares of the Reserve International Liquidity Fund, Ltd. (the International Fund) and the Reserve Primary Fund (the Primary Fund, together the Reserve Funds) for which the Company
has outstanding redemption orders. The Reserve Funds were AAA-rated money market funds which announced redemption delays and suspended trading in September 2008, during the severe disruption in financial markets. The Reserve Funds are in the process
of liquidating their portfolio of investments, which included securities of Lehman Brothers Holdings, Inc. (Lehman Brothers)

which was downgraded and has filed for Chapter 11 bankruptcy protection. The Primary Fund has received an United States Security Exchange Commission
(SEC) order providing that the SEC will supervise the distribution of assets from the Primary Fund. The redemptions from the International Fund are subject to pending litigation which could cause further delay in any redemption of our
investments.

The Company assessed the fair value of its money market funds, including by consideration of Level 2 and Level 3 inputs (see
Note 4. Fair Value Measurements) for the Reserve Funds and their underlying securities. Based on this assessment, the Company recorded an impairment of the Reserve Funds of $11.8 million during the third quarter 2008, incorporating the Reserve
Funds valuation at zero for debt securities of Lehman Brothers held, and a net asset value of $0.97 per share communicated by the Primary Fund.

The Company has reclassified its investment in shares of the Reserve Funds from Level 1 to Level 3 of the fair value hierarchy due to the inherent subjectivity and significant judgment related to the fair value of the
shares of the Reserve Funds and their underlying securities (see Note 4. Fair Value Measurements). Accordingly, the Company changed the valuation method from a market approach to an income approach.

In addition, due to the status of the Reserve Funds, the Company reclassified all of these shares from cash and cash equivalents to short-term
investments.

The Companys investments in money market funds are classified in the Consolidated Balance Sheet as follows:



|                       |  |                  |       |                  |   |

Changes in market conditions and the method and timing of the liquidation process of the Reserve
Funds could result in further adjustments to the fair value and classification of these investments, and these changes could be material.

On January 31, 2009, the Company received $134.9 million as a partial cash distribution from the International Fund.

As of December 28, 2008, the Company had no deposits related to long-term supplier contracts
(2007$4 million). During 2008, the Company recognized a $4.3 million asset impairment charge in the Consolidated Statement of Operations related to the termination of a supplier contract, of which $3.8 million was from other assets in the
table above and the balance from prepaid expenses and other current assets.

##### Table of Contents

During 2006, the Company recorded a $3.2 million impairment loss on its investment in a private company,
which was its carrying value. This was offset by a $0.1 million gain on sale of another investment. In addition, the Company sold its investment in Ikanos Communications Inc. in 2006 for proceeds of $5.1 million and recorded a gain of $3.1 million,
included in Loss on investments on the Consolidated Statement of Operations.

The Company monitors the value of its investments for
impairment and records an impairment charge to reflect any decline in value below its cost basis, if that decline is considered to be other than temporary. The assessment of impairment in carrying value is based on the market value trends of similar
public companies, the current business performance of the entities in which we have invested, and if available, the estimated future market potential of the companies and venture funds.

NOTE 9. Lines of credit

At December 28, 2008, the Company had available a revolving line of credit
with a bank under which the Company may borrow up to $0.8 million with interest at the banks alternate base rate (annual rate of 3.75% at December 28, 2008) as long as the Company maintains eligible investments with the bank in an amount
equal to its drawings. This agreement will expire in July 2009. At December 28, 2008, $0.8 million cash was deposited with the bank to offset the amount committed under letters of credit used as security for a facility lease.

NOTE 10. Long-term debt



|2.25% | Senior convertible notes
|----- | ------------------------

On October 26, 2005, the
Company issued $225 million aggregate principal amount of 2.25% senior convertible notes due 2025 (Notes). The Company has recorded these Notes as long-term debt and issuance costs of $6.8 million have been deferred and will be amortized
over seven years, which is the Companys earliest call date. This approximates the effective interest method.

The notes rank equal in
right of payment with our other unsecured senior indebtedness and mature on October 15, 2025 unless earlier redeemed by the Company at its option, or converted or put to the Company at the option of the holders. Interest is payable
semi-annually in arrears on April 15 and October 15 of each year, commencing on April 15, 2006. The Company may redeem all or a portion of the Notes at par on and after October 20, 2012. The holders may require that the Company
repurchase the Notes on October 15, 2012, 2015 and 2020 respectively.

Holders may convert the Notes into the right to receive the
conversion value (i) when the Companys stock price exceeds 120% of the approximately $8.80 per share initial conversion price for a specified period, (ii) in certain change in control transactions, and (iii) when the trading
price of the Notes does not exceed a minimum price level. For each $1,000 principal amount of Notes, the conversion value represents the amount equal to 113.6687 shares multiplied by the per share price of the Companys common stock at the time
of conversion. If the conversion value exceeds $1,000 per $1,000 in principal of Notes, the Company will pay $1,000 in cash and may pay the amount exceeding $1,000 in cash, stock or a combination of cash and stock, at the Companys election.

The Company entered into a Registration Rights Agreement with the holders of the Notes, under which the Company is required to keep the
shelf registration statement effective until the earlier of (i) the sale pursuant to the shelf registration statement of all of the Notes and/or shares of common stock issuable upon conversion of the Notes, and (ii) the expiration of the
holding period applicable to such securities held by non-affiliates under Rule 144(k) under the Securities Act, or any successor provision, subject to certain permitted exceptions.

The Company will be required to pay liquidated damages, subject to some limitations, to the holders of the Notes if the Company fails to comply with its
obligations to register the Notes and the common stock issuable

upon conversion of the notes or the registration statement does not become effective within the specified time periods. In no event will liquidated damages
accrue after the second anniversary of the date of issuance of the notes or at a rate exceeding 0.50% of the issue price of the Notes. The Company will have no other liabilities or monetary damages with respect to any registration default. If the
holder has converted some or all of its Notes into common stock, the holder will not be entitled to receive any liquidated damages with respect to such common stock or the principal amount of the Notes converted.

During 2008, the Company repurchased $156.7 million principal amount of our Notes for $138.3 million and expensed $3.2 million of related unamortized
debt issue costs and transaction costs resulting in a net gain of $15.2 million. At December 28, 2008, $68.3 million of these Notes remained outstanding and $1.1 million of deferred debt issue costs were included in Investments and other
assets.

Legal
Matters:

SEC Informal Inquiry

On
August 18, 2006, PMC received an informal confidential request from the SEC advising that the SEC commenced an informal inquiry into the Companys historical stock option-granting practices. The Company engaged outside counsel to represent
it in the inquiry. On December 6, 2006, a meeting took place at the SEC in San Francisco during which the Audit Committee and its special counsel summarized the results of its investigation into the Companys historical option-granting
practices. In February 2007, the Company completed all the SECs requests for information related to its inquiry. On October 26, 2007, the SEC staff formally notified the Company that its inquiry was terminated and that no enforcement
action against the Company had been recommended to the SEC.

Stockholder Derivative Lawsuits

Three derivative actions have been filed against the Company, as a nominal defendant, and various current and former officers and/or
directors: (1) Meissner v. Bailey, et al., Santa Clara Superior Court Case No. 1-06-CV-071329 (filed September 18, 2006); (2) Beiser v. Bailey, et al., United States District Court for the Northern District of California
Case No. 5:06-CV-05330-RS (filed August 29, 2006); and (3) Barone v. Bailey, et al., United States District Court for the Northern District of California (the Federal Court) Case No. 4:06-CV-06473-SBA (filed
October 16, 2006). On November 21, 2006, the Beiser and Barone actions were consolidated into one case. On January 18, 2007, the Santa Clara County Superior Court in California ordered that the Meissner action be stayed
pending the outcome of the consolidated, federal Beiser/Barone action.

The Beiser/Barone plaintiffs generally allege that various current
and former Company directors and/or officers breached their duty of loyalty and/or duty of care to the Company and its stockholders in connection with improperly dating certain employee stock option grants and that these purported breaches of
fiduciary duties caused harm to the Company. The plaintiffs seek to recover damages on behalf of the Company. They also allege violations of federal securities laws. The Company is a nominal defendant, but any recovery in the litigation
would be paid to the Company, rather than to its stockholders. The defendants have entered into joint defense arrangements.

The
defendants moved to dismiss the Beiser/Barone action on various legal grounds including that the plaintiffs failed to state a claim and failed to plead with particularity facts establishing that a litigation demand on the board of directors of
the Company would have been futile at the time they commenced the derivative lawsuit. The Federal Court dismissed the consolidated complaint on August 22, 2007 and gave plaintiffs leave to amend. The Federal Court dismissed the
plaintiffs first amended consolidated complaint on May 8, 2008 and permitted plaintiffs leave to amend one last time. Defendants moved to dismiss the second amended complaint which motions were to be heard on August 20,
2008.

On July 15, 2008, Ian Beiser, a named plaintiff in the Beiser/Barone action, filed a complaint in
the Delaware Court of Chancery, and it was served on July 18, 2008, compelling the Company to permit plaintiff to inspect and make copies of the Companys books and records. On August 5, 2008, the plaintiffs moved to stay the Federal
Court action pending the books and records action. The Federal Court granted the motion to stay on August 13, 2008, which removed from the calendar the hearing on defendants motions to dismiss, previously scheduled for August 20,
2008.

On December 11, 2008, the Delaware Court of Chancery heard argument on the books and records demand and the parties are
awaiting the Courts order.

As at December 28, 2008, the Company has not accrued costs for potential losses related to the
amended consolidated action.

Operating Leases:

The Company leases its facilities under operating lease agreements, which expire at various dates through September 30, 2013.

Rent expense including operating costs for the years ended December 28, 2008, December 30, 2007, and December 31, 2006 was $10.9 million, $10.8 million, and $10.5 million, respectively. Excluded from rent expense for
2008 was additional rent and operating costs of $3.9 million (2007$4.6 million; 2006$4.2 million) related to excess facilities, which were accrued as part of the restructuring programs.

Minimum future rental payments under operating leases are as follows:

Supply agreements. The Company has supply agreements with Chartered, TSMC, and UMC. Under
these agreements, the foundries must supply certain quantities of wafers per year. Neither of these agreements have minimum unit volume requirements. The agreements may be terminated if either party does not comply with the terms. The Company has a
history of renewing contracts on an annual basis with its foundries for those agreements that require renewals, and the Company does not anticipate any problems with renewing such agreements beyond their expiring dates.

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 12. Special Shares

At December 28, 2008 and December 30, 2007, the Company maintained a reserve of 2,045,000 and 2,065,000, respectively, of PMC
common stock to be issued to holders of PMC-Sierra, Ltd. (LTD) special shares.

##### Table of Contents

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 13. Stockholders Equity

Authorized capital stock of PMC. At December 28, 2008 and
December 30, 2007, the Company had an authorized capital of 905,000,000 shares, 900,000,000 of which are designated Common Stock, $0.001 par value, and 5,000,000 of which are designated Preferred Stock, $0.001 par value.

Stockholders' Rights Plan. The Company adopted a stockholder rights plan in 2001, pursuant to which the Company declared a dividend
of one share purchase right for each outstanding share of common stock. If certain events occur, including if an investor tenders for or acquires more than 15% of the Companys outstanding common stock, stockholders (other than the acquirer)
may exercise their rights and receive $650 worth of our common stock in exchange for $325 per right, or the Company may, at the Companys option, issue one share of common stock in exchange for each right, or the Company may redeem the rights
for $0.001 per right.

NOTE 14. Employee Benefit Plans

Post-retirement Health Care Benefits.Our unfunded post retirement benefit plan, which was assumed in connection with the acquisition of the Storage Semiconductor Business, provides retiree medical benefits to eligible United
States employees who meet certain age and service requirements upon retirement from the Company. These benefits are provided from the date of retirement until the employee qualifies for Medicare coverage. The amount of the retiree medical benefit
obligation assumed by the Company was $1.1 million at the time of the acquisition.

At December 28, 2008, the accumulated
postretirement benefit obligation was $1.1 million, with no unrecognized gain/loss or unrecognized prior service cost. The net period benefit cost was $0.3 million during 2008. No distributions were made from the plan during the period. The Company
includes accrued benefit costs for its post-retirement program in Accrued liabilities on the Companys Consolidated Balance Sheet.

The health care accumulated postretirement benefit obligations were determined at December 28, 2008 using a discount rate of 6% and a current year health care trend of 10% decreasing to an ultimate trend rate of 5.0% in 2014.

Employee Retirement Savings Plans.The Company sponsors a 401(k) retirement plan for its employees in the United States and similar
plans for its employees in Canada and other countries. Employees can contribute a

The recovery was primarily as a result of one of the Companys foreign subsidiaries settling
several ongoing tax matters for less than had been accrued as part of its liability for unrecognized tax benefits, resulting in the recognition of a $124.1 million tax benefit. In addition, prior to the settlement, the Company accrued $35.2 million
(including associated interest) relating to an ongoing liability arising from the examination of our existing transfer pricing practices, $28.1 million of income tax from normal operations (offset by investment tax credits of $19.5 million), $5.8
million deferred tax expense from an unrealized gain arising from foreign currency translation pertaining to a foreign subsidiary, and $4.5 million increase in tax from various items, including deferred taxes, minimum taxes and revisions of prior
estimates.

##### Table of Contents

Despite the net loss for 2007, income taxes were incurred primarily from a $28 million additional accrual
relating to an ongoing FIN 48 liability arising from the examination of our historic transfer pricing policies and practices of certain companies within the PMC Group by a certain tax authority. Of the $28 million increase in our FIN 48 liability,
$13.1 million is related to arrears interest. Our FIN 48 liability is partially offset by available investment tax credits earned in the year of $18 million. The remainder of the provision for income taxes primarily relates to $6 million of deferred
taxes recorded with respect to a past acquisition and net $1 million due to various items, including revisions of prior estimates.

The
Companys estimated tax provision rate increased significantly at the end of 2006 due to an increase in its estimated tax liability following receipt in 2007 of a written communication from a tax authority examining the historic transfer
pricing policies and practices of certain companies within the PMC-Sierra group. As a result, in 2006, the Company increased its provision for periods prior to 2006 by $29.9 million.

Significant components of the Companys deferred tax assets and liabilities are as follows:

At December 28, 2008, the Company has approximately $533.8 million of federal net operating
losses, which will expire through 2027. The Company also has approximately $222.5 million of state tax loss carryforwards, which expire through 2017. A portion of our net operating losses were used in 2006 and 2008 to reduce the taxes otherwise
payable on intercompany dividends. The utilization of a portion of these net operating losses may be subject to annual limitations under federal and state income tax legislation. Substantially all of our net operating losses and capital losses
relate to the Companys domestic operations and no tax benefit has been recorded for these losses.

Included in the credit
carry-forwards are $7.3 million of investment tax credits, which expire through 2028, $16.7 million of federal research and development credits which expire through 2025, $4.3 million of federal alternative minimum tax credits which carryforward
indefinitely, $11.0 million of state research and development credits which do not expire, and $0.5 million of state manufacturers investment credits which expire through 2012.

##### Table of Contents

Included in the deferred tax assets before valuation allowance are approximately $116.8 million of
cumulative tax benefits related to equity transactions, which will be credited to stockholders equity if and when realized.

The
pretax income from foreign operations was $63.9 million, $30.4 million, and $48.2 million in 2008, 2007, and 2006, respectively. The Company recorded $4.3 million tax expense related to earnings it repatriated in 2008. In addition, the Company
recorded $7.1 million tax expense in 2006 related to earnings it repatriated to fund the purchase of the Storage Semiconductor Business. These distributions do not change the Companys intent to indefinitely reinvest undistributed earnings of
the Companys foreign subsidiaries and accordingly, no additional provision for federal and state income taxes has been provided thereon. It is not practical to estimate the income tax liability that might be incurred on the remittance of such
earnings.

A reconciliation of the beginning and ending balances of the total amounts of gross unrecognized tax benefits is as follows (in
millions):

|Gross unrecognized tax benefits December 28, 2008              |  | $                | 22.9   |   |                  | $ | 125.6 |  
|                                                               |  |                  |        |   |                  |   |       |  

The total amount of gross unrecognized tax benefits that, if recognized, would affect the
effective tax rate was $22.9 million at December 28, 2008 (2007$125.6 million). The Company accrues interest and penalties related to unrecognized tax benefits in its provision for income taxes. At December 28, 2008, the Company had
accrued interest and penalties related to unrecognized tax benefits of $3.8 million (2007$46.8 million). See Note 1 to the consolidated financial statements for additional disclosures related to the adoption of FIN 48.

The Company and its subsidiaries file income tax returns in the U.S. and in various states, local and foreign jurisdictions. The 2004 through 2008 tax
years generally remain subject to examination by federal and most state tax authorities. In significant foreign jurisdictions, the 2004 through 2008 tax years generally remain subject to examination by their respective tax authorities. The Company
does not reasonably estimate that the unrecognized tax benefit will change significantly within the next 12 months.

During 2008, the Company had two customers, whose purchases represented a significant portion of
net revenues, based on billing, including contract manufacturers and distributors. Net revenues from one customer represented approximately 14% of net revenues in 2008 (200712%, 200612%) Net revenues from a second customer were 14% of
net revenues in 2008 (200711%, 200612%).

During 2008, the Company did not have any end customers, whose purchases represented
10% or more of net revenues. In 2007 and 2006, the Company had two end customers whose purchases represented 13% and 11% of our total net revenues, respectively.

|------- | -------------------------------------------------------------------------------------

None.



|ITEM 9A. | Controls and Procedures.
|-------- | ------------------------

In evaluating the
effectiveness of our internal control over financial reporting as of December 28, 2008, we considered the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal
Control-Integrated Framework. Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitations. Internal control over financial reporting is a process
that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting also can be circumvented by collusion or improper management override. Because
of such limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting. Also, projections of any evaluation of effectiveness to future periods are subject to
the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

A material weakness is a control deficiency, or combination of control deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be
prevented or detected.

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

Our chief executive officer and our chief financial officer evaluated our disclosure controls and procedures as defined in Rules 13a-15(e) and
15d-15(e) of the Securities Exchange Act of 1934 as amended (the Exchange Act) as of December 28, 2008. They concluded that as of the evaluation date, our disclosure controls and procedures are effective to ensure that information
we are required to disclose in reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely
decisions regarding required disclosure, and that such information is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms.

Managements Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) and 15d
-15(f) of the Securities Exchange Act of 1934 as amended).

Our management assessed the effectiveness of our internal control over
financial reporting using the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control  Integrated Framework. Based on our assessment and those criteria, management
believes that we maintained effective control over financial reporting as of December 28, 2008.

Because of its inherent limitations,
internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions,
or that the degree of compliance with the policies or procedures may deteriorate.

Deloitte & Touche LLP, the independent
registered public accounting firm that audited the financial statements included in this Annual Report, has issued an attestation report on the registrant's internal control over financial reporting. The report is included herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of PMC-Sierra, Inc.

We have audited the internal control over financial reporting of PMC-Sierra, Inc. and subsidiaries (the Company) as of December 28, 2008, based on criteria established in Internal ControlIntegrated Framework
issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal
control over financial reporting, included in the accompanying Managements Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based
on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of
internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we
considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal
control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors,
management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A
company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets
of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the
company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the
company's assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control
over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the
effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may
deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of
December 28, 2008, based on the criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial
statements and financial statement schedules as of and for the year ended December 28, 2008 of the Company and our report dated February 25, 2009 expressed an unqualified opinion on those financial statements and financial statement
schedules and included an explanatory paragraph regarding the Companys adoption of Statement of Financial Accounting Standard No. 157, Fair Value Measurements, effective January 1, 2008.
