the data center virtualization market and, in connection therewith, had decided to discontinue development of these products. We immediately reduced our resources and began a process to sell
assets devoted to the development of these products.

On June 17, 2009, we completed the acquisition of Galazar Networks,
Inc. (Galazar). Galazar, based in Ottawa, Ontario, Canada, was a fabless semiconductor and software supplier focused on carrier grade transport over telecom networks. Galazars product portfolio addresses transport of a wide range
of networking and telecom services including Ethernet, TDM, Fiber Channel and video over SONET/SDH, PDH and OTN networks.

On
April 3, 2009, we completed the acquisition of hi/fn, inc. (Hifn), a fabless semiconductor company that was founded in 1996, spun off from Stac, Inc. in 1999 and traded on The NASDAQ Stock Market under the symbol HIFN
since 1999. The acquisition of Hifn expanded and complemented our product offering in the enterprise storage, networking and telecom markets where we have had a significant base of business for more than 10 years. The Hifn technology added world
class compression and data deduplication products used in storage applications to optimize data and speed up data backup and retrieval. Hifn had also been a leading provider in security acceleration technology by providing encryption and compression
products to leading networking and telecom system manufacturers. The Hifn products complement our connectivity solutions and provide us with a more significant product offering to our customers.

On August 25, 2007, we acquired Sipex Corporation (Sipex), a fabless semiconductor company that designed, manufactured
and marketed high performance, analog integrated circuits (ICs) used by original equipment manufacturers (OEMs) in the computing, consumer electronics, communications and networking infrastructure markets.

Our products are organized into four product lines, which provide product definition based on market opportunities and trends. Product
line orientation also allows for the concentration of technical expertise around the common market and strategic customer focus to bond product solutions to the largest users in a given market segment. Our product lines are defined as Interface
Products, Power Management Products, Communications Products and Datacom and Storage Products.

We believe our core competencies and key
initiatives include:

Leading Analog and Mixed-Signal Design ExpertiseWe have over 40 years of proven
technical competency in developing analog and mixed-signal ICs. As a result, we have developed a deep understanding of the subtleties of analog and mixed-signal design and a comprehensive library of analog core blocks. We leverage this expertise
across the broad range of products we develop. From programmable power management chips to advanced telecom products, our products share a heavy concentration of analog and mixed-signal content to achieve high performance, power efficient solutions.

Comprehensive Solutions to Enhance System IntegrationThe combination of our design expertise, diverse
circuit technology and system-level expertise enables us to provide comprehensive solutions that encompass hardware, software and applications support. For example, we have developed many digital blocks and engines that are used in data aggregation,
transmission, acceleration and computer offload. We believe that by using our solutions, OEMs can develop higher performance systems, better leverage their development resources and reduce their time-to-market.

Connectivity SolutionsA focus on connectivity remains a key strategic direction that drives our product
strategies and serves as a foundation for customer engagements. Expanding the range of connectivity solutions has driven our acquisition activity in the last two years. With the addition of system architecture expertise we have extended our
portfolio of products to offer new silicon products, cards and software to support the demand for system solutions in addition to component products. Our connectivity solutions span a range of applications

that serve industrial, networking, storage and telecom applications. Our devices facilitate and optimize the virtual handshake between systems and across networks.

Compelling Performance SolutionsWe use our systems expertise and our analog, digital and mixed-signal design
techniques to architect high-performance products based on standard Complementary Metal Oxide Semiconductor (CMOS) process technologies. The diversity of our technology enables us to develop differentiated solutions for our target
markets.

Conscious Preservation InitiativeEnvironmental concerns have a direct impact on electronic
components and products. We are committed to reducing the impact that the end use and manufacturing of our products may have on the environment. We have taken the initiative to offer a portfolio of green products by transitioning our
manufacturing processes to offer parts that meet or exceed the Restriction of Hazardous Substances Directive (RoHS) requirements and are halogen-free.

MARKETS AND PRODUCTS

Datacom and Storage

Our datacom and storage product portfolio provides a range of solutions for OEMs to efficiently optimize, secure, and transport data in
next generation data centers. Our value proposition is driven by underlying hardware offload technology. The concept behind hardware offload is to use efficient, dedicated hardware to provide functionality that would otherwise need to be done with
power-hungry and costly host processors. General-purpose application processors are very flexible, but inefficient. The advantages of hardware offload are:



| |  |  | High performance and scalabilitythe hardware is dedicated to a specific task and architected for parallelism
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | Low powerdedicated hardware is highly efficient
| | - |  | ------------------------------------------------



| |  |  | Data integrityresults of calculations can be checked in real time without performance degradation
| | - |  | --------------------------------------------------------------------------------------------------

Our datacom and storage solutions provide hardware offload capabilities that are an ideal complement to the capabilities of costly
application processors. Using application processors to perform tasks such as encrypting data or inspecting packets rather than executing application software is very inefficient. The result is higher operating costs and the need for additional,
expensive hardware  as well as data center floor space to install it, the capability to cool it, and the headcount to manage it. A dedicated Exar device can perform encryption several times faster than two fully dedicated quad core,
multi-threaded server microprocessors at approximately 2% of the power. This is just one example of the value hardware offload can provide in an enterprise environment.

We provide a variety of solutions to help manage the growing requirements placed on the network and storage infrastructure found in many organizations. These solutions provide the capability to minimize
the data footprint with compression, secure data with encryption and eliminate redundancy with deduplication. Our product portfolio is targeted at resolving these issues with a range of innovative solutions:



| |  |  | Data Security and CompressionOur line of ASIC and PCI-Express add-in card solutions provide a range of functionality necessary for data
encryption/authentication and data compression. These hardware solutions are supported by a comprehensive software suite to enable rapid time-to-market. The flexibility of these products enables high performance, low power solutions for both
data-at-rest in storage environments as well as data-in-motion in networking applications. All of these solutions are engineered for end-to-end data integrity critical for protecting user data.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Data DeduplicationOur BitWackr product provides a comprehensive solution for in-line data deduplication for primary and backup
storage applications. These solutions offload the computationally intensive tasks necessary from the host processor to allow high performance, power efficient implementations of the data deduplication function as well as enabling data to be
simultaneously compressed and encrypted for storage.

Line Interface Units (LIUs) and LIU/framer combinations that incorporate reconfigurable, relayless redundancy (Exar R3Technology) with integrated termination resistors and jitter attenuation. Used individually or in chip sets, our
T1/E1 technologies offer customers key advantages including design flexibility, enhanced system reliability and standards compliance, which are critical components of high-density, low-power system boards and line-cards. In addition, our T1/E1/J1
Framer/LIU combination products simplify the design process by saving board space and by reducing complexity as a result of lowering component count. In addition to T1/E1 solutions, we have developed a diverse portfolio of single- and multi-channel
T3/E3 physical interface solutions with integrated LIU logic and jitter attenuation that achieve high performance levels while reducing board space and overall power in multi-port applications.

SONET/SDH

Synchronous Optical NETwork (SONET) and Synchronous Digital Hierarchy (SDH) protocols are the backbone of
todays high-capacity, long distance communications networks. Our portfolio of SONET/SDH products process data at speeds from 155Mb/s to 40Gb/s for the efficient transport of digital data over fiber optic networks. Products include mixed signal
clock and data recovery (CDR) circuits, transceivers, protocol framers and service mappers. Our high density, high-integration products enable significant flexibility in line card design coupled with cost, area and power savings.

OTN

With the substantial growth of internet, wireless and broadband traffic, the demands on service providers for faster, high bandwidth and more reliable networks for ubiquitous services resulted in the
development of the Optical Transport Networks (OTN) protocol. Optimized for long distance transmission of data at speeds starting at 2.5 Gb/s and exceeding 100 Gb/s, OTN has been accepted as the global technology for the next generation
of optical networks. We are developing a portfolio of products optimized for the efficient mapping of Ethernet, SONET/SDH, OTN, video, storage and data services over high capacity OTN networks. These multiservice products enable flexible, low power,
any service, any port line cards.

Carrier Ethernet Services

The exponential increase of internet traffic within service provider networks has created a need for products to efficiently map internet
data onto the existing PDH and SONET/SDH digital networks and evolving OTN network. As the ubiquitous interface for internet and data traffic in general, Ethernet mappers are key components for the transformation of the network from circuit based to
packet based transport. Our extensive portfolio of Ethernet over PDH (EoPDH), Ethernet over SONET/SDH (EoS) and Ethernet over OTN products enable the efficient mapping of Ethernet packets into flexible bandwidth transport
networks.

Power Management

The power management market is a large and diverse semiconductor segment that spans a broad range of technologies. We have developed solutions for DC/DC voltage conversion and supervision designed to meet
the needs of industrial, communication and computer systems as well as other electronic devices.

PowerXRTM, our line of programmable power management products, provides system designers with the ability to reconfigure the
power management sub-system throughout the development cycle and, if required, even in the field. By using
PowerXRtechnology, product development cycles can be
reduced from many months to several weeks with the flexibility and configurability of this programmable solution. We are at the forefront of the industry in providing the high performance and cost effective programmable power solutions that make
this change in product development methodology possible.

The Power Delivery System

LOGO

PowerXRproducts utilize proprietary technology that has evolved from our previous acquisitions of Sipex and FyreStorm, a
collaborative development partnership with the University of Toronto and our internal engineering team.
PowerXRtechnology combines digital control and monitoring
with our high performance analog circuitry, enabling the system architect to design products that reduce wasted energy by orders of magnitude and are reconfigurable on the fly. This allows the designer to easily manage product changes and perform
true what-if analysis. Our proprietary technology enables efficient partitioning of the digital and analog circuitry within the IC, creating the ability to tailor products to match the application requirements in a fraction of the area required by
other non-configurable technologies.

Power management products, whether digitally controlled or analog, require world class
analog process capability and design tools and methodologies to win in todays markets. As a fabless semiconductor manufacturer, we have access to the broad range of wafer fabrication facilities that are driving innovation in analog process
technology and have developed strong relationships with the worlds leading suppliers of analog and mixed-signal silicon. This access to leading edge process technology coupled with our ongoing investment in analog and mixed-signal design
automation tools has made us competitive with the worlds leading manufacturers of analog power management products.

While we believe our programmable power products represent a fundamental change in the capability of power management devices, many of todays products are better served by traditional analog power
components. For these applications, we have a full line of non-programmable power products which utilize the same state-of-the-art analog circuitry and design tools as found in PowerXRproducts. Our portfolio of power products is focused on a range of solutions that offer power management, voltage
conversion and LED control. In each area, we have delivered products that offer differentiating capabilities based on innovative circuit design and integration. We have built upon our strong heritage of analog and mixed-signal capability with the
addition of proprietary technology, enabling the creation of world class products that will continue to evolve as our customers requirements become ever more complex. This differentiated, proprietary portfolio of power products

has been developed with the goal to make power system design easy. In doing so, we seek to lower the cost and labor burden on our customers so that they do not need to become power
experts. We enable them to focus on resolving their higher level system related challenges.

Strategy

We strive to be a leading provider of highly differentiated silicon, software and subsystem solutions for industrial, telecom, networking
and storage applications. To achieve our long-term business objectives, we employ the following strategies:

Leverage
Analog and Mixed-Signal Design Expertise to Provide Integrated System-Level SolutionsUtilizing our analog and mixed-signal design expertise, we integrate mixed-signal physical interface devices for a broad range of silicon
solutions. This capability continues to be the backbone of our integration strategy and enables us to offer optimized solutions to the markets we serve. Our customers depend on analog and mixed-signal integration for power reduction, size
optimization and signal integrity.

Expand Product PortfolioWe have developed a strong presence in the
broad industrial, telecom, networking and storage markets where we have industry leading customers and proven technological capabilities. Our design expertise has enabled us to offer a diverse portfolio of both industry standard and proprietary
products serving a range of connectivity and power management needs. Our extensive product portfolio provides the framework for customers to work with many of our products on a single board design. Our ability to serve the various needs of a
customers system enables us to meet procurement and support needs by providing a single point of contact for applications support and supply chain management while reducing their number of vendors.

Grow Market Share with System SolutionsWe create systems solutions by coupling system expertise,
software and advanced silicon integration to provide an optimized solution that is designed to be technically compelling and cost effective, resulting in distinctive products like Tethys, 10G Sonet Multiplexer (Mux)/DeMux, DX1700
and DX1800 Cards, Bitwackr data deduplication solutions and PowerXR. These solutions and others provide platform-level engagements that involve software and hardware integration, resulting in a cohesive bond with customers.

Strengthen and Expand Strategic OEM RelationshipsTo promote the early adoption of our solutions, we actively seek
collaborative relationships with strategic OEMs during product development. We believe that OEMs recognize the value of our early involvement because designing their system products in parallel with our development can accelerate time-to-market for
their end products. Collaborative relationships also help us to obtain early design wins and to increase the likelihood of market acceptance of our new products, while giving us the advantage of being the incumbent device provider on future
generations of our customers platforms.

Use Standard CMOS and Bipolar CMOS-DMOS (BCD) Process
Technologies to Provide Compelling Price/Performance SolutionsWe design our products to be manufactured using standard CMOS and BCD processes. We believe that these processes are proven, stable and predictable and benefit from the
extensive semiconductor-manufacturing infrastructure devoted to CMOS and BCD processes. In certain specialized cases, we may use other process technologies to take advantage of their performance characteristics.

Employ Fabless Semiconductor ModelWe have long-standing relationships with third-party wafer foundries and assembly
and test subcontractors to manufacture our ICs. Our fabless approach allows us to avoid substantial capital spending, obtain competitive pricing, minimize the negative effects of industry cycles, reduce time-to-market, reduce technology and product
risks, and facilitate the migration of our products to new CMOS and BCD process technologies. By employing the fabless model, we can focus on our core competencies in product design, development and support as well as on sales and marketing.

Broaden Sales Coverage with Channel PartnersWe have strong relationships with our distributors, catalog
firms and sales representatives throughout the world representing a significant portion of our total

revenue. Through our partners, we have access to large market segments that we cannot directly support. Through these relationships, we extend our expertise and product exposure by enabling our
partners to discover new demands for our solutions as well as aid us in defining our next generation solutions.

Expand our
Business Through Strategic Commercial TransactionsThe markets in which we compete require a wide variety of technologies, products and capabilities. The combination of technological complexity and rapid change within our markets
makes it difficult for a single company to develop all the solutions that it desires to offer within its family of products. Through acquisitions, we aim to deliver a broader range of products to customers in target markets. We employ the following
strategies to address the need for new or enhanced products: we develop new technologies and products internally; we acquire field proven third-party intellectual property cores to accelerate time to market; and we acquire all or parts of other
companies.

Sales and Customers

We market our products globally through both direct and indirect channels. In the United States, we are represented by 19 independent sales representatives and two independent, non-exclusive primary
distributors, as well as our own direct sales organization. In addition, we are represented by three catalog distributors. We currently have domestic presences in or near Boston, Massachusetts; Chicago, Illinois; Dallas, Texas; Raleigh, North
Carolina and Fremont, California.

Internationally, we are represented in Canada, Europe and Asia by our wholly-owned foreign

No other distributor
accounted for 10% or more of our net sales in fiscal year 2011, 2010 or 2009.

We work directly with many key customers
including, among others, Alcatel-Lucent, Cisco Systems Inc., Delta, EchoStar Corporation, EMC Corporation, Ericsson Inc., Fujitsu Limited, Hewlett-Packard Company, Huawei Technologies Co., Ltd., IBM Corporation, LG Electronics Inc., NEC Corporation,
Nokia Siemens Networks, Pace, Panasonic Corporation, Parrot SA, Samsung Electronics Co. Ltd, Tellabs, Inc., United Telecom, and ZTE Corporation.

Manufacturing

We outsource all of our fabrication and assembly as well as
the majority of our testing operations. This fabless manufacturing model allows us to focus on product design, development and support as well as on sales and marketing.

Our products are manufactured using standard CMOS, bipolar, BiCMOS (bipolar CMOS) and BCD process technologies. We use wafer foundries located in the United States and Asia to manufacture our
semiconductor wafers.

Most of our semiconductor wafers are shipped directly from our foundries to our subcontractors in Asia
for wafer test and assembly, where the wafers are cut into individual die and packaged. Independent contractors in China, Indonesia, Malaysia and Taiwan perform most of our assembly work. Final test and quality assurance are performed at our
subcontractors facilities in Asia or at our Fremont, California facility. All of our primary manufacturing partners are certified to ISO 9001:2000 and are, or we expect soon will be, automotive specification TL16949 compliant.

We will continue to use the turnkey manufacturing model for our acquired Hifn and Galazar products currently in production, with our
suppliers delivering fully assembled and tested products based on our proprietary designs.

Research and Development

We believe that ongoing innovation and introduction of new products in our targeted and adjacent markets is essential to sustaining
growth. Our ability to compete depends on our ability to offer technologically innovative products on a timely basis. As performance demands and the complexity of ICs have increased, the design and development process has become a multi-disciplinary
effort requiring diverse competencies. Our research and development is focused on developing high-performance analog, digital and mixed-signal solutions addressing the high-bandwidth requirements of communications and storage systems OEMs and the
high-current, high-voltage requirements of interface and power management OEMs. We make investments in advanced design tools, design automation and high-performance intellectual property libraries while taking advantage of readily available
specialty intellectual property through licensing or purchases. We also augment our skill sets and intellectual property through university collaboration, incorporating talent through acquisition and by accessing needed skills with off-campus design
centers. We continue to pursue the development of design methodologies that are optimized for reducing design-cycle time and increasing the likelihood of first-time success. As a result of the Hifn acquisition, we now have a substantive research and
development presence in the Peoples Republic

of China (PRC) and have a research and development presence in Canada resulting from our acquisitions of Galazar and Neterion. We invested an aggregate of $51.1 million, $48.5 million
and $31.8 million on research and development in fiscal years 2011, 2010 and 2009, respectively. For further explanation of our increased expenses in research and development, please see Part II, Item 7Managements
Discussion and Analysis of Financial Condition and Results of Operations.

Competition

The semiconductor industry is intensely competitive and is characterized by rapid technological change and a history of price reductions
as design improvements and production efficiencies are achieved in successive generations of products. Although the market for analog and mixed-signal ICs is generally characterized by longer product life cycles and less dramatic price reductions
than the market for digital ICs, we face substantial competition in each market in which we participate.

We believe that the
principal competitive factors in the market segments in which we operate are:



| |  |  | time-to-market;
| | - |  | ---------------



| |  |  | product performance, quality, reliability and features;
| | - |  | -------------------------------------------------------



| |  |  | customer support and services;

| |  |  | product innovation; and
| | - |  | -----------------------



| |  |  | compliance with and support of industry standards.
| | - |  | --------------------------------------------------

We compete with many other companies and many of our current and potential competitors may have certain advantages over us such as:



| |  |  | longer presence in key markets;
| | - |  | -------------------------------



| |  |  | greater name recognition;
| | - |  | -------------------------

Semiconductor Corporation, Pioneer Corporation, Semtech Corporation, Sharp Electronics Corporation, Sony Corporation and Texas Instruments Incorporated. SeePart I, Item 1ARisk FactorsIf we are unable to compete
effectively with existing or new competitors, we will experience fewer customer orders, reduced revenues, reduced gross margins and lost market share.

Backlog

Our sales are made pursuant to either purchase orders for current
delivery of standard items or agreements covering purchases over a period of time, which are frequently subject to revisions and, to a lesser extent, cancellations with little or no penalties. Lead times for the release of purchase orders depend on
the scheduling practices of the individual customer, and our rate of bookings varies from month-to-month. Certain distributors agreements allow for stock rotations, scrap allowances and volume discounts. Further, we defer recognition of
revenue on shipments to certain distributors until the product is resold. For all of these reasons, we believe backlog as of any particular date should not be used as a predictor of future sales.

Intellectual Property Rights

To protect our intellectual property, we rely on a combination of patents, mask work registrations, trademarks, copyrights, trade secrets, and employee and third-party nondisclosure agreements. As of
March 27, 2011, we have 211 patents issued and 30 patent applications pending in the United States and 79 patents issued and 162 patent applications pending in various foreign countries. Our existing patents will expire between 2012 and 2030,
or sooner if we choose not to pay renewal fees. We may also enter into license agreements or other agreements to gain access to externally developed products or technologies. While our intellectual property is critically important, we do not believe
that our current or future success is materially dependent upon any one patent.

Despite our protection efforts, we may fail
to adequately protect our intellectual property. Others may gain access to our trade secrets or disclose such trade secrets to third parties without our knowledge. Some or all of our pending and future patent applications may not result in issued
patents that provide us with a competitive advantage. Even if issued, such patents, as well as our existing patents, may be challenged and later determined to be invalid or unenforceable. Others may develop similar or superior products without
access to or without infringing upon our intellectual property, including intellectual property that is protected by trade secret and patent rights. In addition, the laws of certain territories in which our products are or may be developed,
manufactured or sold, including Asia, Europe, the Middle East and Latin America, may not protect our products and intellectual property rights to the same extent as the laws of the United States of America.

We cannot be sure that our products or technologies do not infringe patents that may be granted in the future pursuant to pending patent
applications or that our products do not infringe any patents or proprietary rights of third parties. Occasionally, we are informed by third parties of alleged patent infringement. In the event that any relevant claims of third-party patents are
found to be valid and enforceable, we may be required to:



| |  |  | stop selling, incorporating or using our products that use the infringed intellectual property;
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | obtain a license to make, sell or use the relevant technology from the owner of the infringed intellectual property, although such license may not be
available on commercially reasonable terms, if at all; or
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | redesign our products so as not to use the infringed intellectual property, which may not be technically or commercially feasible or meet customer
requirements.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------

If we are required to take any of the actions described above or defend against any claims
from third parties, our business, financial condition and results of operations could be harmed. See Part I, Item 1ARisk FactorsWe may be unable to protect our intellectual property rights, which could harm our
competitive position and We could be required to pay substantial damages or could be subject to various equitable remedies if it were proven that we infringed the intellectual property rights of others.

|ITEM 1A. | RISK FACTORS
|-------- | ------------

Global capital,
credit market, employment, and general economic conditions, and resulting declines in consumer confidence and spending, could have a material adverse effect on our business, operating results and financial condition.

Periodic declines or fluctuations in the U.S. dollar, corporate results of operations, interest rates, inflation or deflation, the
global impact of sovereign debt, economic trends, actual or feared economic recessions, lower spending, the impact of conflicts throughout the world, terrorist acts, natural disasters (such as the recent earthquake and tsunami in Japan), volatile
energy costs, the outbreak of communicable diseases and other geopolitical factors, have had, and may continue to have, a negative impact on the U.S. and global economies. Volatility and disruption in the global capital and credit markets have led
to a tightening of business credit and liquidity, a contraction of consumer credit, business failures, higher unemployment, and declines in consumer confidence and spending in the U.S. and internationally. If global economic and financial
market conditions deteriorate or remain weak for an extended period of time, many related factors could have a material adverse effect on our business, operating results, and financial condition, including the following:



| |  |  | slower spending by consumers and market fluctuations may result in reduced demand for our products, reduced orders for our products, order
cancellations, lower revenues, increased inventories, and lower gross margins;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | if we undertake restructuring activities due to economic pressure, we cannot guarantee that any of our restructuring efforts will be successful, or
that we will be able to realize the cost savings and other anticipated benefits from our previous or future restructuring plans, in addition, if we reduce our workforce, it may adversely impact our ability to respond rapidly to new growth
opportunities;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we may be unable to predict the strength or duration of market conditions or the effects of consolidation of our customers in their industries, which
may result in project delays or cancellations;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we may be unable to find suitable investments that are safe or liquid, or that provide a reasonable return resulting in lower interest income or longer
investment horizons, and disruptions to capital markets or the banking system may also impair the value of investments or bank deposits we currently consider safe or liquid;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the failure of financial institution counterparties to honor their obligations to us under credit instruments could jeopardize our ability to rely on
and benefit from those instruments, and our ability to replace those instruments on the same or similar terms may be limited under poor market conditions;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | continued volatility in the markets and prices for commodities, such as gold, and raw materials we use in our products and in our supply chain could
have a material adverse effect on our costs, gross margins, and profitability;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | if distributors of our products experience declining revenues, or experience difficulty obtaining financing in the capital and credit markets to
purchase our products, or experience severe financial difficulty, it could result in insolvency, reduced orders for our products, order cancellations, inability to timely meet payment obligations to us, extended payment terms, higher accounts
receivable, reduced cash flows, greater expenses associated with collection efforts, and increased bad debt expenses;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | if contract manufacturers or foundries of our products or other participants in our supply chain experience difficulty obtaining financing in the
capital and credit markets to purchase raw materials or to finance general working capital needs, it may result in delays or non-delivery of shipments of our products;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | potential shutdowns or over capacity constraints by our third-party foundries or assembly and test subcontractors could result in longer lead-times,
higher buffer inventory levels and degraded on-time delivery performance; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the current macroeconomic environment also limits our visibility into future purchases by our customers and renewals of existing agreements, which may
necessitate changes to our business model.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our expense levels are based, in part, on expectations of future revenues and are, to a
large extent, fixed in the short-term. Our revenues are difficult to predict and at times we have failed to achieve revenue expectations. We may be unable to adjust spending in a timely manner to compensate for any unexpected revenue shortfall. If
revenue levels are below expectations for any reason, our business, financial condition and results of operations could be materially and adversely impacted.

As of March 27, 2011, Soros Fund Management LLC, as principal investment manager for Quantum Partners LP (Soros), beneficially owned approximately 15% of our common stock, and
affiliates of Future, Alonim Investments Inc. and two of its affiliates (collectively Alonim), beneficially owned approximately 17% of our common stock. As such, Alonim and Soros are our largest stockholders. These substantial ownership
positions enable Alonim and Soros to significantly influence matters requiring stockholder approval, which may or may not be in our best interests or the interest of our other stockholders. In addition, Alonim is an affiliate of Future and an
executive officer of Future is on our board of directors, which could lead to actual or perceived influence from Future.

Alonim and Soros each own a significant percentage of our outstanding shares. Due to such ownership, Alonim and Soros, acting
independently or jointly, may be able to exert strong influence over actions requiring the approval of our stockholders, including the election of directors, many types of change of control transactions and amendments to our charter documents.
Further, if one of these stockholders were to sell or even propose to sell a large number of their shares, the market price of our common stock could decline significantly.

Although we have no reason to believe it to be the case, the interests of these significant stockholders could conflict with our best interests or the interests of the other stockholders. For example, the
significant ownership percentages of these two stockholders could have the effect of delaying or preventing a change of control or otherwise discouraging a potential acquirer from obtaining control of us, regardless of whether the change of control
is supported by us and our other stockholders. Conversely, by virtue of their percentage ownership of our stock, Alonim and/or Soros could facilitate a takeover transaction that our board of directors and/or a significant portion of our other
stockholders did not approve.

Further, Alonim is an affiliate of Future, our largest distributor, and Pierre Guilbault, the
chief financial officer of Future, is a member of our board of directors. These relationships could also result in actual or perceived attempts to influence management to take actions beneficial to Future which may or may not be beneficial to us or
in our best interests. Future could attempt to obtain terms and conditions more favorable than those we would typically provide our distributors because of its relationship with us. Any such actual or perceived preferential treatment could
materially and adversely affect our business, financial condition and results of operations.

Our fixed operating expenses and practice
of ordering materials in anticipation of projected customer demand could make it difficult for us to respond effectively to sudden swings in demand and result in higher than expected costs and excess inventory. Such sudden swings in demand could
therefore have a material adverse impact on our business, financial condition and results of operations.

Our operating
expenses are relatively fixed in the short to medium term, and therefore, we have limited ability to reduce expenses quickly and sufficiently in response to any revenue shortfall. In addition, we typically plan our production and inventory levels
based on forecasts of customer demand, which is highly unpredictable and can fluctuate substantially. From time to time, in response to anticipated long lead times to obtain inventory and materials from our outside suppliers and foundries, we may
order materials in advance of anticipated customer demand. This advance ordering may result in excess inventory levels or unanticipated inventory write-downs if expected orders fail to materialize. This incremental cost could have a materially
adverse impact on our business, financial condition and results of operations.

Our growth depends in part on our successful continued development and customer acceptance of new products for our core markets. We must: (i) anticipate customer and market requirements and changes
in technology and industry standards; (ii) properly define and develop new products on a timely basis; (iii) gain access to and use technologies in a cost-effective manner; (iv) have suppliers produce quality products;
(v) continue to expand our technical and design expertise; (vi) introduce and cost-effectively manufacture new products on a timely basis; (vii) differentiate our products from our competitors offerings; and (viii) gain
customer acceptance of our products. In addition, we must continue to have our products designed into our customers future products and maintain close working relationships with key customers to define and develop new products that meet their
evolving needs. Moreover, we must respond in a rapid and cost-effective manner to shifts in market demands, to increased functional integration and other changes. Migration from older products to newer products may result in volatility of earnings
as revenues from older products decline and revenues from newer products begin to grow.

Products for our customers
applications are subject to continually evolving industry standards and new technologies. Our ability to compete will depend in part on our ability to identify and ensure compliance with these industry standards. The emergence of new standards could
render our products incompatible. We could be required to invest significant time, effort and expense to develop and qualify new products to ensure compliance with industry standards.

The process of developing and supporting new products is complex, expensive and uncertain, and if we fail to accurately predict and
understand our customers changing needs and emerging technological trends, our business, financial condition and results of operations may be harmed. In addition, we may make significant investments to modify new products according to input
from our customers who may choose a competitors or an internal solution, or cancel their projects. We may not be able to identify new product opportunities successfully, develop and bring to market new products, achieve design wins, ensure
when and which design wins actually get

released to production, or respond effectively to technological changes or product announcements by our competitors. In addition, we may not be successful in developing or using new technologies
or may incorrectly anticipate market demand and develop products that achieve little or no market acceptance. Our pursuit of technological advances may require substantial time and expense and may ultimately prove unsuccessful. Failure in any of
these areas may materially and adversely harm our business, financial condition and results of operations.

We have made and in the
future may make acquisitions and significant strategic equity investments, which may involve a number of risks. If we are unable to address these risks successfully, such acquisitions and investments could have a materially adverse effect on our
business, financial condition and results of operations.

We have recently undertaken a number of strategic
acquisitions, have made strategic investments in the past, and may make further strategic acquisitions and investments from time to time in the future. The risks involved with these acquisitions and investments include:



| |  |  | the possibility that we may not receive a favorable return on our investment or incur losses from our investment or the original investment may become
impaired;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | revenues or synergies could fall below projections or fail to materialize as assumed;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | failure to satisfy or set effective strategic objectives;
| | - |  | ---------------------------------------------------------



| |  |  | the opportunity cost associated with committing capital in such transactions;
| | - |  | -----------------------------------------------------------------------------



| |  |  | the possibility of litigation arising from these transactions;
| | - |  | --------------------------------------------------------------



| |  |  | our assumption of known or unknown liabilities or other unanticipated events or circumstances; and
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | the diversion of managements attention from day-to-day operations of the business and the resulting potential disruptions to the ongoing
business.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------

Additional risks involved with acquisitions include:



| |  |  | difficulties in integrating and managing various functional areas such as sales, engineering, marketing, and operations;
| | - |  | ------------------------------------------------------------------------------------------------------------------------



| |  |  | difficulties in incorporating or leveraging acquired technologies and intellectual property rights in new products;
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | difficulties or delays in the transfer of manufacturing flows and supply chains of products of acquired businesses;
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | failure to retain and integrate key personnel;
| | - |  | ----------------------------------------------



| |  |  | failure to retain and maintain relationships with existing customers, distributors, channel partners and other parties;
| | - |  | -----------------------------------------------------------------------------------------------------------------------



| |  |  | failure to manage and operate multiple geographic locations both effectively and efficiently;
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | failure to coordinate research and development activities to enhance and develop new products and services in a timely manner that optimize the assets
and resources of the combined company;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | difficulties in creating uniform standards, controls (including internal control over financial reporting), procedures, policies and information
systems;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | unexpected capital equipment outlays and continuing expenses related to technical and operational integration;
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | difficulties in entering markets or retaining current markets in which we have limited or no direct prior experience and where competitors in such
markets may have stronger market positions;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | insufficient revenues to offset increased expenses associated with acquisitions;
| | - |  | --------------------------------------------------------------------------------



| |  |  | under-performance problems with an acquired company;
| | - |  | ----------------------------------------------------



| |  |  | issuance of common stock that would dilute our current stockholders percentage ownership;

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



| |  |  | incurring large and immediate write-offs of assets.
| | - |  | ---------------------------------------------------

Strategic equity investments also involve risks associated with third parties managing the funds and the risk of poor strategic choices or execution of strategic and operating plans.

We may not address these risks successfully without substantial expense, delay or other operational or financial problems, or at all. Any
delays or other such operations or financial problems could materially and adversely impact our business, financial condition and results of operations.

If we are unable to convert a significant portion of our design wins into revenue, our business, financial condition and results of operations could be materially and adversely impacted.

We continue to secure design wins for new and existing products. Such design wins are necessary for revenue growth.
However, many of our design wins may never generate revenues if their end-customer projects are unsuccessful in the market place or the end-customer terminates the project, which may occur for a variety of reasons. Mergers, consolidations or cost
reduction activities among our customers may lead to termination of certain projects before the associated design win generates revenue. If design wins do generate revenue, the time lag between the design win and meaningful revenue is typically
between six months to greater than eighteen months. If we fail to convert a significant portion of our design wins into substantial revenue, our business, financial condition and results of operations could be materially and adversely impacted.
Under recent deteriorating global economic conditions, our design wins could be delayed even longer than the typical lag period and our eventual revenue could be less than anticipated from products that were introduced within the last eighteen to
thirty-six months, which would likely materially and adversely affect our business, financial condition and results of operations.

The
complexity of our products may lead to errors, defects and bugs, which could subject us to significant costs or damages and adversely affect market acceptance of our products.

Although we, our customers and our suppliers rigorously test our products, they may contain undetected errors, performance weaknesses,
defects or bugs when first introduced or as new versions are released. If any of our products contain production defects or reliability, quality or compatibility problems that are significant to our customers, our reputation may be damaged and
customers may be reluctant to continue to buy our products, which could adversely affect our ability to retain and attract new customers. In addition, these defects or bugs could interrupt or delay sales of affected products, which could materially
and adversely affect our business, financial condition and results of operations.

If defects or bugs are discovered after
commencement of commercial production, we may be required to make significant expenditures of capital and other resources to resolve the problems. This could result in significant additional development costs and the diversion of technical and other
resources from our other development efforts. We could also incur significant costs to repair or replace defective products or may agree to be liable for certain damages incurred. These costs or damages could have a material adverse effect on our
business, financial condition and results of operations.

We derive a substantial portion of our revenues from distributors, especially from our two primary
distributors, Future Electronics Inc. (Future), a related party, and Nu Horizons Electronics Corp. (Nu Horizons). Our revenues would likely decline significantly if our primary distributors elected not to promote or sell our
products or if they elected to cancel, reduce or defer purchases of our products.

Future and Nu Horizons have
historically accounted for a significant portion of our revenues, and they are our two primary distributors worldwide. We anticipate that sales of our products to these distributors will continue to account for a significant portion of our revenues.
The loss of either Future or Nu Horizons as a distributor, for any reason, or a significant reduction in orders from either of them would materially and adversely affect our business, financial condition and results of operations.

Sales to Future and Nu Horizons are made under agreements that provide protection against price reduction for their inventory of our
products. As such, we could be exposed to significant liability if the inventory value of the products held by Future and Nu Horizons declined dramatically. Our distributor agreements with Future and Nu Horizons do not contain minimum purchase
commitments. As a result, Future and Nu Horizons could cease purchasing our products with short notice or cease distributing these products. In addition, they may defer or cancel orders without penalty, which would likely cause our revenues to
decline and materially and adversely impact our business, financial condition and results of operations.

In January 2011
Arrow Electronics, Inc. acquired Nu Horizons. It is uncertain at this point what effect, if any, the acquisition may have on our relationship with the combined company going forward. As Nu Horizons is currently one of our two primary
distributors, if the relationship were to be terminated or altered in an unfavorable fashion, it could result in a material and adverse effect on our business, financial condition and/or results of operations.

If we are unable to accurately forecast demand for our products, we may be unable to efficiently manage our inventory.

Due to the absence of substantial non-cancelable backlog, we typically plan our production and inventory levels based on customer
forecasts, internal evaluation of customer demand and current backlog, which can fluctuate substantially. As a consequence of inaccuracies inherent in forecasting, inventory imbalances periodically occur that result in surplus amounts of some of our
products and shortages of others. Such shortages can adversely impact customer relations and surpluses can result in larger-than-desired inventory levels, either of which can materially and adversely impact our business, financial condition and
results of operations. Due to the unpredictability of global economic conditions and increased difficulty in forecasting demand for our products, we could experience an increase in inventory levels.

In instances where we have hub agreements with certain vendors, the inability of our partners to provide accurate and timely information
regarding inventory and related shipments of the inventory may impact our ability to maintain the proper amount of inventory at the hubs, forecast usage of the inventory and record accurate revenue recognition which could materially and adversely
impact our business, financial conditions and the results of operations.

If our distributors or sales representatives stop selling or
fail to successfully promote our products, our business, financial condition and results of operations could be materially and adversely impacted.

We sell many of our products through sales representatives and distributors, many of which sell directly to OEMs, contract manufacturers and end customers. Our non-exclusive distributors and sales
representatives may carry our competitors products, which could adversely impact or limit sales of our products. Additionally, they could reduce or discontinue sales of our products or may not devote the resources necessary to sell our
products in the volumes and within the time frames that we expect. Our agreements with distributors contain limited provisions for return of our products, including stock rotations whereby distributors may return a percentage of



24



---

##### Table of Contents

their purchases from us based upon a percentage of their most recent three or six months of shipments. In addition, in certain circumstances upon termination of the distributor relationship,
distributors may return some portion of their prior purchases. The loss of business from any of our significant distributors or the delay of significant orders from any of them, even if only temporary, could materially and adversely impact our
business, financial conditions and results of operations.

Moreover, we depend on the continued viability and financial
resources of these distributors and sales representatives, some of which are small organizations with limited working capital. In turn, these distributors and sales representatives are subject to general economic and semiconductor industry
conditions. We believe that our success will continue to depend on these distributors and sales representatives. If some or all of our distributors and sales representatives experience financial difficulties, or otherwise become unable or unwilling
to promote and sell our products, our business, financial condition and results of operations could be materially and adversely impacted.

Our distributors rely heavily on the availability of short-term capital at reasonable rates to fund their ongoing operations. If this capital is not available, or is only available on onerous terms,
certain distributors may not be able to pay for inventory received or we may experience a reduction in orders from these distributors, which would likely cause our revenue to decline and materially and adversely impact our business, financial
condition and results of operations.

We depend in part on the continued service of our key engineering and management personnel and our
ability to identify, hire, incentivize and retain qualified personnel. If we lose key employees or fail to identify, hire, incentivize and retain these individuals, our business, financial condition and results of operations could be materially and
adversely impacted.

Our future success depends, in part, on the continued service of our key design engineering,
technical, sales, marketing and executive personnel and our ability to identify, hire, motivate and retain other qualified personnel.

Under certain circumstances, including a company acquisition or business downturn, current and prospective employees may experience uncertainty about their future roles with us. Volatility or lack of
positive performance in our stock price and the ability to offer equity compensation to as many key employees or in amounts consistent with market practices, as a result of regulations regarding the expensing of equity awards, may also adversely
affect our ability to retain key employees, all of whom have been granted equity awards. In addition, competitors may recruit our employees, as is common in the high tech sector. If we are unable to retain personnel that are critical to our future
operations, we could face disruptions in operations, loss of existing customers, loss of key information, expertise or know-how, and unanticipated additional recruiting and training costs.

Competition for skilled employees having specialized technical capabilities and industry-specific expertise is intense and continues to
be a considerable risk inherent in the markets in which we compete. At times, competition for such employees has been particularly notable in California, Canada and the Peoples Republic of China (PRC). Further, the PRC historically
has different managing principles from Western style management and financial reporting concepts and practices, as well as different banking, computer and other control systems, making the successful identification and employment of qualified
personnel particularly important, and hiring and retaining a sufficient number of such qualified employees may be difficult. As a result of these factors, we may experience difficulty in establishing management, legal and financial controls,
collecting financial data, books of account and records and instituting business practices that meet Western standards, which could materially and adversely impact our business, financial condition and results of operations.

Our employees are employed at-will, which means that they can terminate their employment at any time. Our international locations are
subject to local labor laws, which are often significantly different from U.S. labor laws and which may under certain conditions result in large separation costs upon termination. The failure to



25

##### Table of Contents

recruit and retain, as necessary, key design engineers and technical, sales, marketing and executive personnel could materially and adversely impact our business, financial condition and results
of operations.

Stock-based awards are critical to our ability to recruit, retain and motivate highly skilled talent. In
making employment decisions, particularly in the semiconductor industry and the geographies where our employees are located, a key consideration of current and potential employees is the value of the equity awards they receive in connection with
their employment. If we are unable to offer employment packages with a competitive equity award component, our ability to attract highly skilled employees would be harmed. In addition, volatility in our stock price could result in a stock
options exercise price exceeding the market value of our common stock or a deterioration in the value of restricted stock units granted, thus lessening the effectiveness of stock-based awards for retaining and motivating employees. Similarly,
decreases in the number of unvested in-the-money stock options held by existing employees, whether because our stock price has declined, options have vested, or because the size of follow-on option grants has declined, may make it more difficult to
retain and motivate employees. Consequently, we may not continue to successfully attract and retain key employees, which could have an adverse effect on our business, financial condition and results of operations.

Occasionally, we enter into agreements that expose us to potential damages that exceed the value of the agreement.

We have given certain customers increased indemnification for product deficiencies or intellectual property infringement that is in excess
of our standard limited warranty and indemnification provision and could possibly result in greater costs, in excess of the original contract value. In an attempt to limit this liability, we have purchased an errors and omissions insurance policy to
partially offset these potential additional costs; however, our insurance coverage could be insufficient in terms of amount and/or coverage to prevent us from suffering material losses if the indemnification amounts are large enough or if there are
coverage issues.

We may be exposed to additional credit risk as a result of the addition of significant direct customers through recent
acquisitions.

From time to time one of our customers has contributed more than 10% of our quarterly net sales. A
number of our customers are OEMs, or the manufacturing subcontractors of OEMs, which might result in an increase in concentrated credit risk with respect to our trade receivables and therefore, if a large customer were to be unable to pay, it could
materially and adversely impact our business, financial condition and results of operations.

Any error in our sell-through revenue
recognition judgment or estimates could lead to inaccurate reporting of our net sales, gross profit, deferred income and allowances on sales to distributors and net income.

Sell-through revenue recognition is highly dependent on receiving pertinent and accurate data from our distributors in a timely fashion.
Distributors provide us periodic data regarding the product, price, quantity, and end customer when products are resold as well as the quantities of our products they still have in stock. We must use estimates and apply judgment to reconcile
distributors reported inventories to their activities. Any error in our judgment could lead to inaccurate reporting of our net sales, gross profit, deferred income and allowances on sales to distributors and net income, which could have an
adverse effect on our business, financial condition and results of operations.

Because a significant portion of our total assets were,
and may again be with future potential acquisitions, represented by goodwill and other intangible assets, which are subject to mandatory annual impairment evaluations, we could be required to write-off some or all of our goodwill and other
intangible assets, which may materially and adversely impact our business, financial condition and results of operations.

A significant portion of the purchase price for any business combination may be allocated to identifiable tangible and intangible assets and assumed liabilities based on estimated fair values at the date
of consummation. As required by U.S Generally Accepted Accounting Principles (GAAP), the excess purchase price, if any, over



26

##### Table of Contents

the fair value of these assets less liabilities typically would be allocated to goodwill. We evaluate goodwill for impairment on an annual basis or whenever events and changes in circumstances
suggest that the carrying amount may not be recoverable. We typically conduct our annual analysis of our goodwill in the fourth quarter of our fiscal year. An in-process research and development (IPR&D) asset is considered an
indefinite-lived intangible asset and is not subject to amortization until the conclusion of development. IPR&D assets must be tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might
be impaired. The impairment test consists of a comparison of the fair value of the IPR&D asset with its carrying amount. If the carrying amount of the IPR&D asset exceeds its fair value, an impairment loss must be recognized in an amount
equal to that excess. After an impairment loss is recognized, the adjusted carrying amount of the IPR&D asset will be its new accounting basis. If the fair value of the IPR&D asset exceeds the carrying amount, no adjustment is recorded.
Subsequent reversal of a previously recognized impairment loss is prohibited. Once the IPR&D projects have been completed, the useful life of the IPR&D asset is determined and amortized accordingly. If the IPR&D project is abandoned, the
carrying amount of the IPR&D project is written off. Intangible assets that are subject to amortization are reviewed for impairment on an annual basis or whenever events and changes in circumstances suggest that the carrying amount may not be
recoverable.

The assessment of goodwill and other intangible assets impairment is a subjective process. Estimations and
assumptions regarding future performance, results of our operations and comparability of our market capitalization and its net book value will be used. Changes in estimates and assumptions could impact fair value resulting in an impairment, which
could materially and adversely impact our business, financial condition and results of operations.

Our business may be materially and
adversely impacted if we fail to effectively utilize and incorporate acquired technology.

We have acquired and may in
the future acquire intellectual property in order to accelerate our time to market for new products. Acquisitions of intellectual property may involve risks relating to, among other things, successful technical integration into new products, market
acceptance of new products and achievement of planned return on investment. Successful technical integration in particular requires a variety of resources which we may not currently have, such as available technical staff with sufficient time to
devote to integration, the requisite skill sets to understand the acquired technology and the necessary support tools to effectively utilize the technology. The timely and efficient integration of acquired technology may be adversely impacted by
inherent design deficiencies or application requirements. The potential failure of or delay in product introduction utilizing acquired intellectual property could lead to an impairment of capitalized intellectual property acquisition costs, which
could materially and adversely impact our business, financial condition and results of operations.

If we are unable to compete
effectively with existing or new competitors, we will experience fewer customer orders, reduced revenues, reduced gross margins and lost market share.

We compete in markets that are intensely competitive, and which are subject to both rapid technological change, continued price erosion and changing business terms with regard to risk allocation. Our
competitors include many large domestic and foreign companies that have substantially greater financial, technical and management resources, name recognition and leverage than we have. As a result, they may be able to adapt more quickly to new or
emerging technologies and changes in customer requirements or to devote greater resources to promote the sale of their products.

We have experienced increased competition at the design stage, where customers evaluate alternative solutions based on a number of factors, including price, performance, product features, technologies,
and availability of long-term product supply and/or roadmap guarantee. Additionally, we experience, in some cases, severe pressure on pricing from some of our competitors or on-going cost reduction expectations from customers. Such circumstances may
make some of our products unattractive due to price or performance measures and result in losing our design opportunities or causing a decrease in our revenue and margins. Also, competition from new companies in emerging economy countries with
significantly lower costs could affect our selling price and gross



27

##### Table of Contents

margins. In addition, if competitors in Asia reduce prices on commodity products, it would adversely affect our ability to compete effectively in that region. Specifically, we have licensed
rights to Hangzhou Silan Microelectronics Co. Ltd. and Hangzhou Silan Integrated Circuit Co. Ltd. (collectively Silan) in China to market our commodity interface products that could reduce our sales in the future should they become a
meaningful competitor. Loss of competitive position could result in price reductions, fewer customer orders, reduced revenues, reduced gross margins and loss of market share, any of which would adversely affect our operating results and financial
condition. To the extent that our competitors offer distributors or sales representatives more favorable terms, these distributors and sales representatives may decline to carry, or discontinue carrying, our products. Our business, financial
condition and results of operations could be harmed by any failure to maintain and expand our distribution network. Furthermore, many of our existing and potential customers internally develop solutions which attempt to perform all or a portion of
the functions performed by our products. To remain competitive, we continue to evaluate our manufacturing operations for opportunities for additional cost savings and technological improvements. If we or our contract partners are unable to
successfully implement new process technologies and to achieve volume production of new products at acceptable yields, our business, financial condition and results of operations may be materially and adversely affected. Our future competitive
performance depends on a number of factors, including our ability to:



| |  |  | increase device performance and improve manufacturing yields;
| | - |  | -------------------------------------------------------------



| |  |  | accurately identify emerging technological trends and demand for product features and performance characteristics;
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | develop and maintain competitive and reliable products;
| | - |  | -------------------------------------------------------



| |  |  | enhance our products by adding innovative features that differentiate our products from those of our competitors;
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | bring products to market on a timely basis at competitive prices;
| | - |  | -----------------------------------------------------------------



| |  |  | respond effectively to new technological changes or new product announcements by others;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | adapt products and processes to technological changes;
| | - |  | ------------------------------------------------------



| |  |  | adopt or set emerging industry standards;
| | - |  | -----------------------------------------



| |  |  | meet changing customer requirements; and
| | - |  | ----------------------------------------



| |  |  | provide adequate technical service and support.
| | - |  | -----------------------------------------------

Our design, development and introduction schedules for new products or enhancements to our existing and future products may not be met. In addition, these products or enhancements may not achieve market
acceptance, or we may not be able to sell these products at prices that are favorable, which could materially and adversely affect on our business, financial condition and results of operations.

We depend on third-party subcontractors to manufacture our products. We utilize wafer foundries for processing our wafers and assembly and test
subcontractors for manufacturing and testing our packaged products. Any disruption in or loss of foundries or subcontractors capacity to manufacture and test our products subjects us to a number of risks, including the potential for an
inadequate supply of products and higher materials costs. These risks may lead to delayed product delivery or increased costs, which could materially and adversely impact our business, financial condition and results of operations.

We do not own or operate a semiconductor fabrication facility or a foundry. We utilize various foundries for different
processes. Our products are based on Complementary Metal Oxide Semiconductor (CMOS) processes, bipolar processes and bipolar-CMOS (BiCMOS) processes. Globalfoundries Singapore Pte. Ltd. (f.k.a. Chartered Semiconductor
Manufacturing Ltd.) (Globalfoundries) manufactures the majority of the CMOS wafers from which the majority of our communications and UART products are produced. Episil Technologies, Inc. (Episil), located in Taiwan, and
Silan, located in China, manufacture the majority of the CMOS and bipolar wafers from which our power and serial products are produced. High Voltage BiCMOS

power products are supplied by Jazz Semiconductor (CA, USA). All of these foundries produce semiconductors for many other companies (many of which have greater requirements than us), and
therefore, we may not have access on a timely basis to sufficient capacity or certain process technologies and we do, from time to time, experience extended lead times on some products. In addition, we rely on our foundries continued financial
health and ability to continue to invest in smaller geometry manufacturing processes and additional wafer processing capacity.

Many of our new products are designed to take advantage of smaller geometry manufacturing processes. Due to the complexity and increased
cost of migrating to smaller geometries as well as process changes, we could experience interruptions in production or significantly reduced yields causing product introduction or delivery delays. If such delays occur, our products may have delayed
market acceptance or customers may select our competitors products during the design process.

New process technologies
or new products can be subject to especially wide variations in manufacturing yields and efficiency. There can be no assurance that our foundries or the foundries of our suppliers will not experience unfavorable yield variances or other
manufacturing problems that result in delayed product introduction or delivery delays.

Our foundries manufacture our products
on a purchase order basis. We provide our foundries with rolling forecasts of our production requirements; however, the ability of our foundries to provide wafers is limited by the foundries available capacity. There can be no assurance that
our third-party foundries will allocate sufficient capacity to satisfy our requirements. In addition, we may not continue to do business with our foundries on terms as favorable as our current terms.

Furthermore, any sudden reduction or elimination of any primary source or sources of fully processed wafers could result in a material
delay in the shipment of our products. Any delays or shortages will materially and adversely impact our business, financial condition and results of operations. In particular, the products produced from the wafers manufactured by Episil and Silan
currently constitute a significant part of our total revenue, and so any delay, reduction or elimination of our ability to obtain wafers from either foundry could materially and adversely impact our business, financial condition and results of
operations.

Our reliance on our wafer foundries and assembly and test subcontractors involves the following risks:



| |  |  | a manufacturing disruption or sudden reduction or elimination of any existing source or sources of semiconductor manufacturing materials or processes,
which might include the potential closure, change of ownership, change in business conditions or relationships, change of management or consolidation by one of our foundries;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | disruption of manufacturing or assembly or test services due to relocation or limited capacity of the foundries or subcontractors;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------



| |  |  | inability to obtain or develop technologies needed to manufacture our products;
| | - |  | -------------------------------------------------------------------------------



| |  |  | extended time required to identify, qualify and transfer to alternative manufacturing sources for existing or new products or the possible inability to
obtain an adequate alternative;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | failure of our foundries or subcontractors to obtain raw materials and equipment;
| | - |  | ---------------------------------------------------------------------------------



| |  |  | increasing cost of commodities, such as gold, raw materials and energy resulting in higher wafer or package costs;
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | long-term financial and operating stability of the foundries, or their suppliers or subcontractors, and their ability to invest in new capabilities and
expand capacity to meet increasing demand, to remain solvent, or to obtain financing in tight credit markets;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | continuing measures taken by our suppliers such as reductions in force, pay reductions, forced time off or shut down of production for extended periods
of time to reduce and/or control operating expenses in response to weakened customer demand;

Our stock price is volatile.

The market price of our common stock has fluctuated significantly to date. In the future, the market price of our common stock could be subject to significant fluctuations due to, among other reasons:



| |  |  | our anticipated or actual operating results;
| | - |  | --------------------------------------------



| |  |  | announcements or introductions of new products by us or our competitors;
| | - |  | ------------------------------------------------------------------------



| |  |  | technological innovations by us or our competitors;
| | - |  | ---------------------------------------------------



| |  |  | investors perception of the semiconductor sector;
| | - |  | --------------------------------------------------



| |  |  | loss of or changes to key executives;
| | - |  | -------------------------------------



| |  |  | product delays or setbacks by us, our customers or our competitors;
| | - |  | -------------------------------------------------------------------



| |  |  | potential supply disruptions;
| | - |  | -----------------------------



| |  |  | sales channel interruptions;
| | - |  | ----------------------------



| |  |  | concentration of sales among a small number of customers;
| | - |  | ---------------------------------------------------------



| |  |  | conditions in our customers markets and the semiconductor markets;
| | - |  | -------------------------------------------------------------------



| |  |  | the commencement and/or results of litigation;
| | - |  | ----------------------------------------------



| |  |  | changes in estimates of our performance by securities analysts;
| | - |  | ---------------------------------------------------------------



| |  |  | decreases in the value of our investments or long-lived assets, thereby requiring an asset impairment charge against earnings;

In the past, securities and class action litigation has been brought against companies following periods of volatility in the market prices of their securities. We may be the target of one or more of
these class action suits, which could result in significant costs and divert managements attention, thereby materially and adversely impact our business, financial condition and results of operations.

In addition, at times the stock market has experienced and is currently experiencing extreme price, volume and value fluctuations that
affect the market prices of the stock of many high technology companies, including semiconductor companies, and that are unrelated or disproportionate to the operating performance of those companies. Any such fluctuations may harm the market price
of our common stock.

Our results of operations could vary as a result of the methods, estimations and judgments we use in applying our
accounting policies.

The methods, estimates and judgments we use in applying our accounting policies have a
significant impact on our results of operations. Such methods, estimates and judgments are, by their nature, subject to substantial risks, uncertainties, assumptions and changes in rulemaking by the regulatory bodies; and factors may arise over time
that lead us to change our methods, estimates, and judgments. Changes in those methods, estimates and judgments could materially and adversely impact our business, financial condition and results of operations. Our revenue reporting is highly
dependent on receiving pertinent and accurate data from our distributors in a timely fashion. Distributors provide us periodic data regarding the product, price, quantity and end customer when products are resold as well as the quantities of our
products they still have in stock. We must use estimates and apply judgment to reconcile distributors reported inventories to their activities. Any error in our judgment could lead to inaccurate reporting of our revenues, deferred income and
allowances on sales to distributors and net income.

The final determination of our income tax liability may be materially different
from our income tax provision, which could have an adverse effect on our business, financial condition and results of operations.

Our future effective tax rates may be adversely affected by a number of factors including:



| |  |  | the jurisdictions in which profits are determined to be earned and taxed;
| | - |  | -------------------------------------------------------------------------



| |  |  | the resolution of issues arising from tax audits with various tax authorities;
| | - |  | ------------------------------------------------------------------------------



| |  |  | changes in the valuation of our deferred tax assets and liabilities;
| | - |  | --------------------------------------------------------------------



| |  |  | adjustments to estimated taxes upon finalization of various tax returns;
| | - |  | ------------------------------------------------------------------------



| |  |  | increases in expenses not deductible for tax purposes, including write-offs of acquired in-process research and development and impairment of goodwill
in connection with acquisitions;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | changes in available tax credits;
| | - |  | ---------------------------------



| |  |  | changes in stock-based compensation expense;
| | - |  | --------------------------------------------



| |  |  | changes in tax laws or the interpretation of such tax laws and changes in generally accepted accounting principles; and/or
| | - |  | --------------------------------------------------------------------------------------------------------------------------



| |  |  | the repatriation of non-U.S. earnings for which we have not previously provided for U.S. taxes.
| | - |  | -----------------------------------------------------------------------------------------------

Any significant increase in our future effective tax rates could adversely impact net income for future periods. In addition, the U.S.
Internal Revenue Service (IRS) and other tax authorities regularly examine our

##### Table of Contents

income tax returns. Our business, financial condition and results of operations could be materially and adversely impacted if these assessments or any other assessments resulting from the
examination of our income tax returns by the IRS or other taxing authorities are not resolved in our favor.

We have acquired
significant Net Operating Loss (NOL) carryforwards as a result of our acquisitions. The utilization of acquired NOL carryforwards is subject to the IRSs complex limitation rules that carry significant burdens of proof. Limitations
include certain levels of a change in ownership. As a publicly traded company, such change in ownership by shareholders, such as Future and Soros, may be out of our control. Our eventual ability to utilize our estimated NOL carryforwards is subject
to IRS scrutiny and our future results may not benefit as a result of potential unfavorable IRS rulings.

Our engagement with foreign
customers could cause fluctuations in our operating results, which could materially and adversely impact our business, financial condition and results of operations.

International sales have accounted for, and will likely continue to account for a significant portion of our revenues, which subjects us to the following risks, among others:



| |  |  | changes in regulatory requirements;
| | - |  | -----------------------------------



| |  |  | tariffs and other barriers;
| | - |  | ---------------------------



| |  |  | timing and availability of export or import licenses;
| | - |  | -----------------------------------------------------



| |  |  | disruption of services due to political, civil, labor, and economic instability;
| | - |  | --------------------------------------------------------------------------------



| |  |  | disruption of services due to natural disasters outside the United States;
| | - |  | --------------------------------------------------------------------------



| |  |  | disruptions to customer operations outside the United States due to the outbreak of communicable diseases;
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | difficulties in accounts receivable collections;
| | - |  | ------------------------------------------------



| |  |  | difficulties in staffing and managing foreign subsidiary and branch operations;
| | - |  | -------------------------------------------------------------------------------



| |  |  | difficulties in managing sales channel partners;
| | - |  | ------------------------------------------------



| |  |  | difficulties in obtaining governmental approvals for communications and other products;
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | limited intellectual property protection;
| | - |  | -----------------------------------------



| |  |  | foreign currency exchange fluctuations;
| | - |  | ---------------------------------------



| |  |  | the burden of complying with foreign laws and treaties;
| | - |  | -------------------------------------------------------



| |  |  | contractual or indemnity issues that are materially different from our standard sales terms; and
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | potentially adverse tax consequences.
| | - |  | -------------------------------------

In addition, because sales of our products have been denominated primarily in U.S. dollars, increases in the value of the U.S. dollar as compared with local currencies could make our products more
expensive to customers in the local currency of a particular country resulting in pricing pressures on our products. Increased international activity in the future may result in foreign currency denominated sales. Furthermore, because some of our
customers purchase orders and agreements are governed by foreign laws, we may be limited in our ability, or it may be too costly for us, to enforce our rights under these agreements and to collect damages, if awarded.

Because some of our IC products have lengthy sales cycles, we may experience substantial delays between incurring expenses related to product
development and the revenue derived from these products.

A portion of our revenue is derived from selling ICs to
communications equipment vendors. Due to their product development cycle, we have typically experienced at least an eighteen-month time lapse between our initial contact with a customer and realizing volume shipments. We first work with customers to
achieve a design

win, which may take nine months or longer. Our customers then complete their design, test and evaluation process and begin to ramp-up production, a period which typically lasts an additional nine
months. The customers of communications equipment manufacturers may also require a period of time for testing and evaluation, which may cause further delays. As a result, a significant period of time may elapse between our research and development
efforts and our realization of revenue, if any, from volume purchasing of our communications products by our customers. Due to the length of the communications equipment vendors product development cycle, the risks of project cancellation by
our customers, price erosion or volume reduction are common aspects of such engagements.

Our backlog may not result in revenue.

Due to the possibility of customer changes in delivery schedules and quantities actually purchased, cancellation of
orders, distributor returns or price reductions, our backlog at any particular date is not necessarily indicative of actual sales for any succeeding period. The still unsettled and weakened economy increases the risk of purchase order cancellations
or delays, product returns and price reductions. We may not be able to meet our expected revenue levels or results of operations if there is a reduction in our order backlog for any particular period and we are unable to replace those sales during
the same period.

Earthquakes and other natural disasters, such as the recent earthquake and tsunami in Japan, may damage our facilities
or those of our suppliers and customers.

The occurrence of natural disasters in certain regions, such as the recent
earthquake and tsunami in Japan, could adversely impact our manufacturing and supply chain, our ability to deliver products on a timely basis (or at all) to our customers and the cost of or demand for our products. Our corporate headquarters in
Fremont, California is located near major earthquake faults that have experienced seismic activity. In addition, some of our other offices, customers and suppliers are in locations which may be subject to similar natural disasters. In the event of a
major earthquake or other natural disaster near our offices, our operations could be disrupted. Similarly, a major earthquake or other natural disaster affecting one or more of our major customers or suppliers could adversely impact the operations
of those affected, which could disrupt the supply or sales of our products and harm our business, financial condition and results of operations.

We may be unable to protect our intellectual property rights, which could harm our competitive position.

Our ability to compete is affected by our ability to protect our intellectual property rights. We rely on a combination of patents, trademarks, copyrights, mask work registrations, trade secrets,
confidentiality procedures and non-disclosure and licensing arrangements to protect our intellectual property rights. Despite these efforts, we may be unable to protect our proprietary information. Such intellectual property rights may not be
recognized or if recognized, may not be commercially feasible to enforce. Moreover, our competitors may independently develop technology that is substantially similar or superior to our technology.

More specifically, our pending patent applications or any future applications may not be approved, and any issued patents may not provide
us with competitive advantages or may be challenged by third parties. If challenged, our patents may be found to be invalid or unenforceable, and the patents of others may have an adverse effect on our ability to do business. Furthermore, others may
independently develop similar products or processes, duplicate our products or processes or design around any patents that may be issued to us.

We could be required to pay substantial damages or could be subject to various equitable remedies if it were proven that we infringed the
intellectual property rights of others.

As a general matter, the semiconductor industry is characterized by ongoing
litigation regarding patents and other intellectual property rights. If a third party were to prove that our technology infringed its intellectual property rights, we could be required to pay substantial damages for past infringement and could be
required to



33



---

##### Table of Contents

pay license fees or royalties on future sales of our products. If we were required to pay such license fees whenever we sold our products, such fees could exceed our revenue. In addition, if it
was proven that we willfully infringed a third partys proprietary rights, we could be held liable for three times the amount of the damages that we would otherwise have to pay. Such intellectual property litigation could also require us to:



| |  |  | stop selling, incorporating or using our products that use the infringed intellectual property;
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | obtain a license to make, sell or use the relevant technology from the owner of the infringed intellectual property, which license may not be available
on commercially reasonable terms, if at all; and/or
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | redesign our products so as not to use the infringed intellectual property, which may not be technically or commercially feasible.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------

The defense of infringement claims and lawsuits, regardless of their outcome, would likely be expensive and
could require a significant portion of managements time. In addition, rather than litigating an infringement matter, we may determine that it is in our best interests to settle the matter. Terms of a settlement may include the payment of
damages and our agreement to license technology in exchange for a license fee and ongoing royalties. These fees could be substantial. If we were required to pay damages or otherwise became subject to such equitable remedies, our business, financial
condition and results of operations would suffer. Similarly, if we were required to pay license fees to third parties based on a successful infringement claim brought against us, such fees could exceed our revenue.

|ITEM 2. | PROPERTIES
|------- | ----------

Our executive
offices and our marketing and sales, research and development, manufacturing, test and engineering operations are located in Fremont, California in two adjacent buildings that we own, which consist of approximately 151,000 square feet. Additionally,
we own approximately 4.5 acres of partially developed property adjacent to our headquarters, which is presently being held for future office expansion.

We also lease smaller facilities in Belgium, Canada, China, Japan, Korea, Malaysia, Taiwan and the United States, which are occupied by administrative offices, sales offices, design centers and field
application engineers.

Based upon our estimates of future hiring, we believe that our current facilities will be adequate to
meet our requirements at least through the next fiscal year.

During fiscal years 2011, 2010 and 2009, we also leased one
additional building in California, totaling approximately 95,700 square feet, which was subleased to a tenant. The sublease began on April 15, 2008 and expired March 31, 2011. In accordance with the lease agreement, the leased building was
returned to the lessor on March 31, 2011. For further discussion of this facility and its effect on our financial condition and results of operations, see Part II, Item 7Managements Discussion and Analysis of Financial

|ITEM 7. | MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
|------- | -------------------------------------------------------------------------------------

The following Managements Discussion and Analysis of Financial Condition and Results of Operations, as well as information
contained in Risk Factors above and elsewhere in this Annual Report on Form 10-K contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of
the Securities Exchange Act of 1934, as amended, that involve risks and uncertainties. Please see Forward Looking Statements in Part I above. Actual results may differ materially from those projected in the forward-looking statements as
a result of various factors, including, among others, those identified above under Part I, Item 1ARisk Factors.

COMPANY OVERVIEW

Exar
Corporation and its subsidiaries (Exar or we) is a fabless semiconductor company that designs, sub-contracts manufacturing and sells highly differentiated silicon, software and subsystem solutions for industrial, telecom,
networking and storage applications. Our core expertise in silicon integration, system architecture and software has enabled the development of innovative solutions designed to meet the needs of the evolving connected world. Our product portfolio
includes power management and interface components, communications products, storage optimization solutions, network security and applied service processors. Applying both analog and digital technologies, our products are deployed in a wide array of
applications such as portable electronic devices, set top boxes, digital video recorders, telecommunication systems, servers, enterprise storage systems and industrial automation equipment. We provide customers with a breadth of component products
and subsystem solutions based on advanced silicon integration.

We market our products worldwide with sales offices and
personnel located throughout the Americas, Europe, and Asia. Our products are sold in the United States through a number of manufacturers representatives and distributors. Internationally, our products are sold through various regional and
country specific distributors with locations around the globe. In addition to our sales offices, we also employ a worldwide team of field application engineers to work directly with our customers.

Our international sales consist of sales that are denominated in U.S. dollars. Our international related operations expenses expose us to
fluctuations in currency exchange rates because our foreign operating expenses are denominated in foreign currency while our sales are denominated in U.S. dollars. Our operating results are subject to quarterly and annual fluctuations as a result of
a variety of factors that could materially and adversely affect our future profitability as described in Part I, Item 1A. Risk FactorsOur Financial Results May Fluctuate Significantly Because Of A Number Of Factors, Many Of Which
Are Beyond Our Control.

On March 16, 2010, we completed the acquisition of Neterion, Inc.
(Neterion), a developer of 10 gigabit Ethernet (10GbE) controller silicon and card solutions optimized for virtualized environments located in Sunnyvale, California. During the course of fiscal 2011, Exar participated in the 10GbE
market and established a limited set of customers but fell short of customer expansion and revenue growth goals for the product line. After assessing our market position, degree of target customer adoption and development roadmap, we announced on
March 4, 2011 that we had decided to exit the data center virtualization market and, in connection therewith, had decided to discontinue development of these products. We immediately reduced our resources and began a process to sell assets
devoted to the development of these products.

On June 17, 2009, we completed the acquisition of Galazar Networks, Inc.
(Galazar), a fabless semiconductor company focused on carrier grade transport over telecom networks based in Ottawa, Ontario, Canada. Galazars product portfolio addressed transport of a wide range of datacom and telecom services
including Ethernet, SAN, TDM and video over SONET/SDH, PDH and OTN networks.

On April 3, 2009, we completed the
acquisition of hi/fn, inc. (Hifn), a provider of network- and storage-security and data reduction products located in Los Gatos, California.

##### Table of Contents

Our fiscal years consist of 52 or 53 weeks. In a 52-week year, each fiscal quarter
consists of 13 weeks. The three fiscal years 2011, 2010 and 2009 are each comprised of 52-week periods. Fiscal year 2012 will consist of 53 weeks. Fiscal years ended March 27, 2011, March 28, 2010 and March 29, 2009 are also
referred to as 2011, 2010 and 2009 unless otherwise indicated.

EXECUTIVE SUMMARY

During fiscal year 2011 net sales increased eight percent as compared to fiscal 2010. The increase reflects significant growth of our
interface and power product lines in the first half of the year followed by significant declines in all product lines in the second half of the year as we, like the semiconductor industry at large, experienced an inventory correction by both
distributors and end customers. We expanded our sales channel relationships in 2011 by adding key partners Arrow Electronics, who acquired our second largest distributor Nu Horizons, and Digi-Key Electronics. We introduced 19 new products to our
target markets.

During fiscal year 2011 our business was affected by the industrys inventory correction, and we had to
make some difficult strategic decisions. As announced in March 2011, we decided to exit the data center virtualization market and, in connection therewith, to discontinue development of our 10GbE network adapter cards. We entered this market in
March 2010 with our acquisition of Neterion and experienced slower market adoption and higher development costs than initially expected. We determined that the current economic and market environment did not provide the potential to deliver
acceptable returns on the required investments in these products.

With the start of fiscal year 2012, we
are excited about the interest generated by PowerXR, our
programmable power management product family, and our new DX family of data security and compression products. We expect to provide samples of our dual channel 10 Gb OTN product, MXP2, this fiscal year. We believe there is significant interest from
top tier optical telecom suppliers for MXP2 as it allows them to replace solutions with multiple expensive and power hungry FPGAs. Although our industry can be cyclical and macroeconomics conditions can be uncertain, we believe we are positioned to
grow our revenue, gross margins and have significantly reduced operating expenses.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The preparation of our financial statements and accompanying disclosures in conformity with U.S. generally accepted
accounting principles (GAAP) requires estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities in the consolidated financial
statements and the accompanying notes. The U.S. Securities and Exchange Commission (SEC) has defined a companys critical accounting policies as policies that are most important to the portrayal of a companys financial
condition and results of operations, and which require a company to make its most difficult and subjective judgments, often as a result of the need to make estimates of matters that are inherently uncertain. Based on this definition, we have
identified our most critical accounting policies and estimates to be as follows: (1) revenue recognition; (2) valuation of inventories; (3) income taxes; (4) stock-based compensation; (5) goodwill; (6) long-lived
assets; and (7) valuation of business combinations; each of which is addressed below. We also have other key accounting policies that involve the use of estimates, judgments and assumptions that are significant to understanding our results. For
additional information, seePart II, Item 8Financial Statements and Supplementary Data and Notes to Consolidated Financial Statements, Note 2Accounting Policies. Although we believe that our estimates,
assumptions and judgments are reasonable, they are based upon information presently available. Actual results may differ significantly from these estimates if the assumptions, judgments and conditions upon which they are based turn out to be
inaccurate.

Revenue Recognition

We recognize revenue in accordance with Financial Accounting Standards Board (FASB) authoritative guidance for Revenue Recognition. Four basic criteria must be met before revenue can be
recognized:(1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the price is fixed or determinable; and (4) collectability is reasonably assured.

We derive revenue principally from the sale of our products to distributors and to OEMs or their contract manufacturers. Our delivery
terms are primarily FOB shipping point, at which time title and all risks of ownership are transferred to the customer.

Software became an element of our revenue upon the acquisition of Hifn in April 2009. To date, software revenue has been an immaterial
portion of our net sales.

Non-distributors

For non-distributors, revenue is recognized when title to the product is transferred to the customer, which occurs upon shipment or delivery, depending upon the terms of the customer order, provided that
persuasive evidence of a sales arrangement exists, the price is fixed or determinable, collection of the resulting receivables is reasonably assured, there are no customer acceptance requirements and there are no remaining significant obligations.
Provisions for returns and allowances for non-distributor customers are provided at the time product sales are recognized. Allowances for sales returns and other reserves are recorded based on historical experience or specific identification of an
event necessitating an allowance.

Our history of actual returns from our non-distributors has not been material and,
therefore, the allowance for sales returns for non-distributor customers is not significant.

Distributors

Agreements with our two primary distributors permit the return of 3% to 5% of their purchases during the preceding quarter for purposes of
stock rotation. For one of these distributors, a scrap allowance of 2% of the preceding quarters purchases is permitted. We also provide discounts to certain distributors based on volume of product they sell for a specific product with a
specific volume range for a given customer over a period not to exceed one year.

We recognize revenue from each of our
distributors using either the sell-in basis or sell-through basis, each as described below. Once adopted, the basis for revenue recognition for a distributor is maintained unless there is a change in circumstances indicating the basis for revenue
recognition for that distributor is no longer appropriate.



| |  |  | Sell-in BasisRevenue is recognized upon shipment if we conclude we meet the same criteria as for non-distributors discussed
above and we can reasonably estimate the credits for returns, pricing allowances and/or other concessions. We record an estimated allowance, at the time of shipment, based upon historical patterns of returns, pricing allowances and other concessions
(i.e., sell-in basis).
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Sell-through BasisRevenue and the related costs of sales are deferred until the resale to the end customer if we grant more
than limited rights of return, pricing allowances and/or other concessions or if we cannot reasonably estimate the level of returns and credits issuable (i.e., sell-through basis). Under the sell-through basis, accounts receivable are
recognized and inventory is relieved upon shipment to the distributor as title to the inventory is transferred upon shipment, at which point we have a legally enforceable right to collection under normal terms. The associated sales and cost of sales
are deferred and are included in deferred income and allowances on sales to distributors in the consolidated balance sheet. When the related product is sold by our distributors to their end customers, at which time the ultimate price we receive is
known, we recognize previously deferred income as sales and cost of sales.

##### Table of Contents

Sell-through revenue recognition is highly dependent on receiving pertinent and accurate
data from our distributors in a timely fashion. Distributors provide us periodic data regarding the product, price, quantity, and end customer when products are resold as well as the quantities of our products they still have in stock. We must use
estimates and apply judgments to reconcile distributors reported inventories to their activities. Any error in our judgment could lead to inaccurate reporting of our net sales, gross profit, deferred income and allowances on sales to
distributors and net income.

Valuation of Inventories

Our policy is to establish a provision for excess inventories, based on the nature of the specific product, that is greater than twelve months of forecasted demand unless there are other factors
indicating that the inventories will be sold at a profit after such periods. Among other factors, management considers known backlog of orders, projected sales and marketing forecasts, shipment activity, inventory-on-hand at our primary
distributors, past and current market conditions, anticipated demand for our products, changing lead times in the manufacturing process and other business conditions when determining if a provision for excess inventory is required. Should the
assumptions used by management in estimating the provision for excess inventory differ from actual future demand or should market conditions become less favorable than those projected by management, additional inventory write-downs may be required,
which would have a negative impact on our gross margins. See Part I, Item 1A. Risk FactorsOur Financial Results May Fluctuate Significantly Because Of A Number Of Factors, Many Of Which Are Beyond Our
Control.

Income Taxes

We determine our deferred tax assets and liabilities based upon the difference between the financial statement and tax bases of our assets and liabilities. We make certain estimates and judgments in
determining income tax expense for financial statement purposes. These estimates and judgments occur in the calculation of certain deferred tax assets and liabilities, which arise from timing differences in the recognition of revenue and expense for
tax and financial statement purposes. Such deferred income 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 base, operating losses and tax credit carryforwards. Changes in tax rates affect the deferred income tax assets and liabilities and are recognized in the period in which the tax rates or benefits are enacted.

We must determine the probability that we will be able to utilize our deferred tax assets. A valuation allowance is provided when it is
more likely than not that some portion or all of a deferred tax asset will not be realized. We measure and recognize uncertain tax positions in accordance with GAAP, whereby we only recognize the tax benefit from an uncertain tax position if it is
more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the merits of the position. See Part II, Item 8Financial Statements and Supplementary Dataand
Notes to Consolidated Financial Statements, Note 18Income Taxes for more details about our deferred tax assets and liabilities

Stock-Based Compensation

We compute the fair value of stock options
utilizing the Black-Scholes model. Calculating stock-based compensation expense requires the input of highly subjective assumptions. The assumptions used in calculating the fair value of stock-based compensation represent our estimates, which
involve inherent uncertainties and the application of management judgment. As a result, if factors change and we use different assumptions, our stock-based compensation expense could be materially different in the future. In addition, we are
required to estimate the expected forfeiture rate and only recognize expense for those shares expected to vest. If our actual forfeiture rate is materially different from our estimate, the stock-based compensation expense could be significantly
different from what we have recorded in the current period. See Part II, Item 8Financial Statements and Supplementary Dataand Notes to the Consolidated Financial Statements, Note 13Stock-Based
Compensation for more details about our assumptions used in calculating the stock-based compensation expenses and equity related transactions during the fiscal year.

Goodwill

Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. We evaluate goodwill for impairment on
an annual basis or whenever events and changes in circumstances suggest that the carrying amount may not be recoverable. We conduct our annual impairment analysis in the fourth quarter of each fiscal year. Impairment of goodwill is tested at the
reporting unit level by comparing the reporting units carrying amount, including goodwill, to the fair value of the reporting unit. The fair value of the reporting unit is estimated using a combination of the income approach that uses
discounted cash flows and the market approach that utilizes comparable companies data. If the carrying amount of the reporting unit exceeds its fair value, goodwill is considered impaired and a second step is performed to measure the amount of
impairment loss. Because we have one reporting unit, we utilize an entity-wide approach to assess goodwill for impairment.

Long-Lived
Assets

We assess the impairment of long-lived assets when events or changes in circumstances indicate that the carrying
value of the assets or the asset grouping may not be recoverable. Factors that we consider in deciding when to perform an impairment review include significant negative industry or economic trends and significant changes or planned changes in our
use of the assets. These factors can also be referred to as triggering events. We measure the recoverability of assets that will continue to be used in our operations by comparing the carrying value of the asset grouping to our estimate of the
related total future undiscounted net cash flows. If an asset groupings carrying value is not recoverable through the related undiscounted cash flows, the asset grouping is considered to be impaired. The impairment is measured by comparing the
difference between the asset groupings carrying value and its fair value. Long-lived assets such as goodwill; intangible assets; and property, plant and equipment are considered non-financial assets, and are recorded at fair value only if an
impairment charge is recognized.

Impairments of long-lived assets are determined for groups of assets related to the lowest
level of identifiable independent cash flows. We operate with one asset group on an enterprise basis. As a result, we believe the lowest identifiable cash flows reside at the enterprise level.

When we determine that the useful lives of assets are shorter than we had originally estimated, we accelerate the rate of depreciation
and/or amortization over the assets new, shorter useful lives. See Goodwill and Other Intangible Asset Impairment in this Managements Discussion and Analysis of Financial Condition and Results of Operations
below for more details regarding charges associated with the shortening of useful lives of certain intangible assets.

Valuation of
Business Combinations

We periodically evaluate potential strategic acquisitions to build upon our existing library of
intellectual property, human capital and engineering talent, in order to expand our capabilities in the areas in which we operate or to acquire complementary businesses.

We account for each business combination by applying the acquisition method, which requires (i) identifying the acquiree; (ii) determining the acquisition date; (iii) recognizing and
measuring the identifiable assets acquired, the liabilities assumed, and any non-controlling interest of Exar in the acquiree at their acquisition date fair value; and (iv) recognizing and measuring goodwill or a gain from a bargain purchase.

Assets acquired and liabilities assumed in a business combination that arise from contingencies are recognized at fair value
on the acquisition date if fair value can be determined during the measurement period. If fair value cannot be determined, we typically account for the acquired contingencies using existing guidance for a reasonable estimate.

##### Table of Contents

To establish fair value, we measure the price that would be received to sell an asset or
paid to transfer a liability in an ordinary transaction between market participants. The measurement assumes the highest and best use of the asset by the market participants that would maximize the value of the asset or the group of assets within
which the asset would be used at the measurement date, even if the intended use of the asset is different.

Goodwill is
measured and recorded as the amount, by which the consideration transferred, generally at the acquisition date fair value, exceeds the acquisition date fair value of identifiable assets acquired, the liabilities assumed, and any non-controlling
interest of Exar in the acquiree. To the contrary, if the acquisition date fair value of identifiable assets acquired, the liabilities assumed, and any non-controlling interest of Exar in the acquiree exceeds the consideration transferred, it is
considered a bargain purchase and we would recognize the resulting gain in earnings on the acquisition date.

In-process
research and development (IPR&D) assets are considered an indefinite-lived intangible asset and are not subject to amortization until its useful life is determined to be no longer indefinite. IPR&D assets must be tested for
impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test consists of a comparison of the fair value of the IPR&D asset with its carrying amount. If the carrying
amount of the IPR&D asset exceeds its fair value, an impairment loss must be recognized in an amount equal to that excess. After an impairment loss is recognized, the adjusted carrying amount of the IPR&D asset will be its new accounting
basis. Subsequent reversal of a previously recognized impairment loss is prohibited. The initial determination and subsequent evaluation for impairment of the IPR&D asset requires management to make significant judgments and estimates. Once the
IPR&D projects have been completed, the useful life of the IPR&D asset is determined and amortized accordingly. If the IPR&D asset is abandoned, the remaining carrying value is written off.

Acquisition-related costs, including finders fees, advisory, legal, accounting, valuation and other professional or consulting fees
are accounted for as expenses in the periods in which the costs are incurred and the services are received, with the exception that the costs to issue debt or equity securities are recognized in accordance with other applicable GAAP.

Fiscal Year 2011 versus Fiscal Year 2010

Communication

Net sales of communication products, including network access, transmission and network transport products, for fiscal year 2011 decreased $0.9 million as compared to fiscal year 2010 primarily due to
lower shipments of our network transport products.

Datacom and Storage

Net sales of datacom and storage products include network access and storage products, encryption, data reduction, packet processing
products as well as 10GbE controller silicon and card solutions from the Neterion acquisition. The $16.9 million in net sales in fiscal year 2011 includes $2.7 million in sales of 10GbE controller products. Excluding the sales of 10GbE products, net
sales of datacom and storage products for fiscal year 2011 decreased $10.8 million as compared to fiscal year 2010 primarily due to slower demand with an inventory correction at certain OEM customers and discontinued programs at a certain customer.

Interface

Net sales of interface products, including UARTs and serial transceiver products, for fiscal year 2011 increased $15.0 million as compared to fiscal year 2010 primarily due to higher sales of serial
transceivers through our Asian distributor channel partners.

Power Management

Net sales of power management products, including DC-DC regulators and LED drivers, for fiscal year 2010 decreased $0.6 million as
compared to fiscal year 2009 primarily due to decreased customer demand with a resulting decrease in units sold in fiscal year 2010 and price erosion on a limited number of products.

Net Sales by Channel

For fiscal years 2011, 2010 and 2009, approximately
40%, 35% and 44%, respectively, of our net sales were derived from product sales to our two primary distributors, Future Electronics Inc. (Future) and Nu Horizons Electronic Corp. (Nu Horizons); and approximately 60%; 65% and
56%, respectively, of our net sales were derived from sales to other distributors, OEM customers and other non-distributors.

Net sales from Hifn, Galazar and Neterion have been included in our consolidated financial
statements since April 4, 2009, June 18, 2009 and March 17, 2010, respectively.

Fiscal Year 2011 versus
Fiscal Year 2010

Net sales to our distributors, for which we recognize revenue on the sell-through basis, for fiscal year
2011 increased by $17.6 million. The increase in sales to these distributors was primarily due to higher sales of our interface and power products.

Net sales to direct customers and other distributors for fiscal year 2011 decreased by $6.5 million from fiscal year 2010. This decrease was primarily attributable to the decrease in net sales in our
datacom and storage products.

Fiscal Year 2010 versus Fiscal Year 2009

Net sales to our distributors, for which we recognize revenue on the sell-through basis, for fiscal year 2010 decreased by $1.2 million
from fiscal year 2009. Net sales to these distributors included $1.1 million in sales of Hifn products. The decrease in sales to these distributors was primarily due to lower sales of our legacy communications and interface products.

Net sales to direct customers and other distributors for fiscal year 2010 increased by $21.0 million from fiscal year 2009 and included
$26.6 million in sales of Hifn, Galazar and Neterion products. Net of the acquired products, net sales decreased $5.6 million during the period primarily due to lower sales of our legacy communications products.

##### Table of Contents

Incremental net sales and gross profit from Hifn, Galazar and Neterion have been included
in our consolidated financial statements since April 4, 2009, June 18, 2009 and March 17, 2010, respectively.

Gross profit represents net sales less cost of sales. Cost of sales includes:



| |  |  | the cost of purchasing finished silicon wafers manufactured by independent foundries;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | the costs associated with assembly, packaging, test, quality assurance and product yields;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | the cost of personnel and equipment associated with manufacturing support and engineering;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | the cost of stock-based compensation associated with manufacturing engineering and support personnel;
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | the amortization of purchased intangible assets and acquired intellectual property;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | the fair value adjustment of acquired inventories;
| | - |  | --------------------------------------------------



| |  |  | the provision for excess and obsolete inventory; and
| | - |  | ----------------------------------------------------



| |  |  | the sale of previously reserved inventory.
| | - |  | ------------------------------------------

We believe that gross margin will fluctuate as a percentage of sales and in absolute dollars due to, among other factors, sales mix, manufacturing costs, our ability to leverage fixed operational costs
across increased shipment volumes and competitive pricing pressure on our products.

Fiscal Year 2011 versus Fiscal Year
2010

Gross profit as a percentage of net sales for fiscal year 2011 decreased 3 percentage points as compared to fiscal
year 2010. The decrease in gross profit as a percentage of sales was primarily due to the write-off of inventory as a result of exiting the 10GbE network interface card market, additional charges for other excess and obsolescence inventory, higher
gold costs and product mix.

Stock-based compensation expense recorded in cost of sales was $0.5 million for both fiscal year
2011 and 2010.

Fiscal Year 2010 versus Fiscal Year 2009

Gross profit as a percentage of net sales for fiscal year 2010 increased $13.1 million, or three percentage points, as compared to fiscal
year 2009. The increase in gross profit as a percentage of sales was primarily due to sales of the Hifn and Galazar products that typically have higher margins and improved manufacturing efficiency.

Stock-based compensation expense recorded in cost of sales was $0.5 million and $0.6 million for fiscal year 2010 and 2009, respectively.

| |  |  | costs related to engineering design tools, mask tooling costs, software amortization, test hardware, and engineering supplies and services;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | amortization of acquired intangible assets such as existing technology and patents/core technology; and
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | facilities expenses.
| | - |  | --------------------

We believe that research and development expenses will fluctuate as a percentage of sales and increase in absolute dollars due to, among other factors, higher mask costs in connection with advanced
process geometries, increased investment in software development, incentives, annual merit increases and fluctuations in reimbursements under a research and development contract.

We anticipate that salary related costs associated with the IPR&D project acquired in business combinations will be resourced through
our existing workforce.

Fiscal Year 2011 versus Fiscal Year 2010

R&D-base expenses increased $1.8 million, or 4%, as compared to fiscal year 2010. The increase was primarily due to increased labor
expenses, software amortization and equipment depreciation associated with the acquisition of Neterion, partially offset by lower mask sets costs and outside services.

In connection with the Hifn acquisition, we assumed a contractual agreement under which certain of our research and development costs are eligible for reimbursement. Amounts collected under this
arrangement are offset against research and development expense. During fiscal year 2011, we received $5.0 million for work performed, which was recorded as an offset to research and development expenses. This was a $0.4 million increase as compared
to fiscal year 2010.

The increase in stock-based compensation expense as compared to the same period a year ago was primarily
due to award based incentives to certain individuals.

The decrease in amortization expenseacquired intangibles as
compared to fiscal year 2011 was result of the completion of the amortization period of an underlying intangible asset recorded in the Hifn acquisition.

Accelerated depreciation and other costs for fiscal year 2011 primarily reflect severance payments associated with the exiting of the 10GbE network interface cards market.

Fiscal Year 2010 versus Fiscal Year 2009

R&D-base expenses increased $13.5 million, or 47%, as compared to fiscal year 2009. The increase was primarily due to increased labor expenses, higher mask tooling costs and software amortization and
equipment depreciation due to the growth of our company as a result of the acquisition of Hifn and Galazar.

As noted above,
in connection with the Hifn acquisition, we assumed a contractual agreement under which certain of our research and development costs are eligible for reimbursement. During fiscal year 2010, Exar received $4.6 million for work performed, which was
recorded as an offset to research and development expenses.

The increase in stock-based compensation expense as compared to
the same period a year ago was primarily due to new stock option and restricted stock unit grants made to Hifn and Galazar employees joining our company and the incremental costs associated with the employee stock option exchange in November 2008.

The growth in amortization expenseacquired intangibles as compared to fiscal year 2009 primarily relates to the
amortization of intangible assets associated with the Hifn and Galazar acquisitions.

Accelerated depreciation and other costs
for fiscal year 2010 are primarily associated with acquired equipment and employee severance costs in connection with our acquisitions.

Selling, General and Administrative (SG&A)

Selling,
general and administrative expenses consist primarily of:



| |  |  | salaries, stock-based compensation and related expenses;
| | - |  | --------------------------------------------------------



| |  |  | sales commissions;
| | - |  | ------------------



| |  |  | professional and legal fees;

##### Table of Contents

We believe that SG&A expenses will fluctuate as a percentage of sales and in absolute
dollars due to, among other factors, variable commissions, legal costs, incentives and annual merit increases.

Fiscal Year
2011 versus Fiscal Year 2010

SG&A-base expenses increased $0.7 million, or 2%, as compared to fiscal year 2010. The
increase was primarily a result of an accrual for a proposed amount to resolve a lease remediation claim and higher commissions and incentives.

The increase in stock-based compensation expense as compared to the same period a year ago was primarily due to award based incentives to certain individuals and performance-based restricted stock units
to our executive staff.

The increase in amortization expense-acquired intangibles relates to intangibles assets recorded in
connection with the Neterion acquisition.

Acquisition related costs and other primarily reflect remaining payments on a
Neterion facility located in Sunnyvale, California, which was vacated in the first quarter of fiscal 2011.

Fiscal Year
2010 versus Fiscal Year 2009

SG&A-base expenses increased $5.5 million, or 16%, in fiscal year 2010 as compared to
fiscal year 2009. The increase was primarily due to increased labor expenses and equipment depreciation due to the growth of our company as a result of the acquisition of Hifn, and to a lesser extent, Galazar.

The increase in stock-based compensation expense as compared to the same period a year ago was primarily due to new stock option and
restricted stock unit grants made to Hifn and Galazar employees joining our company and the incremental costs associated with the employee stock option exchange in November 2008.

Acquisition related costs and other increased $3.8 million as compared to fiscal year 2009. The increase was primarily due to higher
professional fees that are recorded as expenses related to business combinations and the accelerated depreciation of $0.8 million relating to shortened remaining lives of equipment acquired from Hifn, employee separation costs of $0.8 million, and
building exit and moving costs of $0.3 million related to the Hifn Los Gatos facility.

Goodwill and Other Intangible Asset
Impairment

Fiscal Year 2011

In the fourth quarter of fiscal year 2011, we conducted our annual impairment review comparing the fair value of our single reporting unit with its carrying value. As of the test date and as of year-end,
and before consideration of a control premium, the fair value, which was estimated as our market capitalization, exceeded the carrying value of our net assets. As a result, no impairment was recorded for fiscal year 2011.

During the fourth quarter of fiscal year 2011, we decided to exit the data center virtualization market, and, in connection therewith, to
discontinue development of our 10GbE network interface cards. We determined that the current economic and market environment did not provide the potential to deliver acceptable returns on the required investments in these products. As a result, in
the fourth quarter of fiscal year 2011, we abandoned all related in-process research and development. In addition, we began to actively market for sale the related assets of our 10GbE technology, consisting primarily of underlying existing and core
technology intangible assets. Charges related to this decision in the fourth quarter of fiscal year 2011 included $7.5 million for the impairment of intangible assets, which is included within the impairment of intangible assets and goodwill line in
our consolidated statements of operations.

##### Table of Contents

The intangible asset impairment charge of $7.5 million consists of $0.8 million to
write-off abandoned IPR&D and $6.7 million to write-down the carrying value of intangible assets that are held for sale to $0.2 million at March 27, 2011, which represents their estimated fair value less cost to sell based on third party
bids received to date. In June 2011, we completed the asset sale process and received $0.2 million, net of selling costs.

Fiscal Year 2010

In the fourth quarter of fiscal year 2010, we conducted our annual impairment review comparing the fair value of our single reporting unit with its carrying value. As of the test date and as of year-end,
and before consideration of a control premium, the fair value, which was estimated as our market capitalization, exceeded the carrying value of our net assets. As a result, no additional measurement was needed and no impairment was recorded for
fiscal year 2010.

Fiscal Year 2009

During fiscal year 2009, a rapid and severe deterioration of worldwide economic conditions affected our industry and led customers to scale down their levels of production. As a result of third quarter
fiscal year 2009 impairment indicators, we considered the potential impairment of goodwill and other long-lived assets including intangible assets. Indicators that required us to perform an interim impairment review consisted of further weakening in
new orders from our customers throughout the third quarter and into the fourth quarter of fiscal year 2009, as well as the uncertainty of the magnitude and duration of the recession and expectations of industry analysts that demand for
semiconductors would remain weak until economic conditions improved. In addition, we experienced a significant decline in our stock price that reduced our market capitalization below our net asset carrying value for an extended period of time. As a
result of the goodwill and long-lived asset impairment assessments, we recorded a charge totaling $59.7 million in the third quarter of fiscal year 2009. This charge is comprised of $46.2 million related to goodwill and $13.5 million related to
intangible assets, which is included in the impairment of intangible assets and goodwill line in the consolidated statements of operations.

Given the impairment indicators discussed above, we performed an interim goodwill impairment analysis during the third quarter of fiscal year 2009 using a combination of the income approach and the market
approach. The analysis performed compared the implied fair value of goodwill to the carrying amount of goodwill on our balance sheet. Our estimate of the implied fair value of the goodwill was based on the quoted market price of our common stock and
the discounted value of estimated future cash flows over a seven-year period with residual value. The analysis resulted in an impairment charge of approximately $46.2 million, which is included in the impairment of intangible assets and goodwill
line in the consolidated statements of operations, that reduced our carrying value of goodwill to zero.

Solely for the
purposes of establishing inputs for the fair value calculations described above related to goodwill impairment testing, we made the following assumptions. We assumed that the current economic recession would continue through fiscal year 2010,
followed by a recovery period in fiscal years 2011 through 2013 and long-term industry growth past fiscal year 2013. In addition, we applied gross margin assumptions consistent with our historical trends and used a 3% growth factor to calculate the
terminal value of the company, which was consistent with the rate used in the prior years annual impairment test. We used a 14% discount rate to calculate the present value of cash flows and the terminal value, which is slightly higher than
the 12.5% discount rate we used in the prior years annual impairment test, primarily due to increases to the required market risk and small stock premiums.

Given the impairment indicators discussed above, we also performed a test of purchased intangible assets for recoverability. The assessment of recoverability was based upon the assumptions and underlying
cash flow projections prepared for the concurrent interim goodwill impairment test. Our estimate of the implied fair value of the intangible assets was based on the discounted value of estimated future cash flows over a five-year period using a
discount rate of 14%.

##### Table of Contents

The analysis determined that the carrying amount of the intangible assets exceeded the
implied fair value and the difference was allocated to the intangible assets of the impacted asset group on a pro-rata basis using the relative carrying amounts of the assets. We recorded an impairment charge of approximately $13.5 million, which is
included in the impairment of intangible assets and goodwill line in the consolidated statements of operations, of which $9.8 million related to existing technology, $1.4 million to patents/core technology, $1.3 million to distributor relationships,
$0.9 million to customer relationships and $0.1 million to tradenames/trademarks.

Interest Income and
Other, Net

Interest income and other, net primarily consists of:



| |  |  | interest income;
| | - |  | ----------------



| |  |  | sublease income;
| | - |  | ----------------



| |  |  | foreign exchange gains or losses; and
| | - |  | -------------------------------------



| |  |  | realized gains or losses on marketable securities.
| | - |  | --------------------------------------------------

Fiscal Year 2011 versus Fiscal Year 2010

The $1.1 million, or 16%,
decrease in interest income and other, net during fiscal year 2011 as compared to fiscal year 2010 was primarily attributable to a decrease in interest income as a result of lower invested cash balances and lower yield of the investments.

Our sublease income for fiscal 2011 was $1.3 million and was related to the sublet of our Hillview facility located in
Milpitas, California (the Hillview Facility) that was assumed in connection with the acquisition of Sipex Corporation (Sipex) in August 2007. The sublease agreement terminated on March 31, 2011 and, as a result, we
anticipate interest income and other, net to decrease by $1.3 million in the future.

Fiscal Year 2010 versus Fiscal Year
2009

The $2.7 million, or 27%, decrease in interest income and other, net during fiscal year 2010 as compared to fiscal
year 2009 was primarily attributable to a decrease in interest income as a result of lower invested cash balances and lower yield of the investments.

Interest Expense

In connection with the Sipex acquisition, we assumed a
lease financing obligation related to the Hillview Facility. The fair value of the Hillview Facility was estimated at $13.4 million at the time of the acquisition and was included in the property, plant and equipment, net line on the consolidated
balance sheet. In accordance with

##### Table of Contents

purchase accounting, we have accounted for this sale and leaseback transaction as a financing transaction which was included in the long-term lease financing obligations line on our consolidated
balance sheet. The effective interest rate is 8.2%. At the end of the lease term, March 31, 2011, the lease obligation was settled by returning the Hillview Facility to the lessor. In fiscal year 2011, we recorded $1.0 million in interest
expense related to the Hillview Facility, and with the return of the building to the lessor, we expect that interest expense will decrease by the same amount in the future.

Impairment Charges on Investments

We periodically review and determine
whether our investments with unrealized loss positions are other-than-temporarily impaired. This evaluation includes, but is not limited to, significant quantitative and qualitative assessments and estimates regarding credit ratings, collateralized
support, the length of time and significance of a securitys loss position, our intent to not sell the security, and whether it is more likely than not that we will not have to sell the security before recovery of its cost basis. Realized gains
or losses on the sale of marketable securities are determined by the specific identification method and are reflected in the interest income and other, net line on the consolidated statements of operations. Other-than-temporary declines in value of
our investments both marketable and non-marketable, judged to be other-than-temporary, are reported in the impairment charges on investments line in the consolidated statements of operations.

In fiscal year 2010, an investment in GSAA Home Equity with a cost of $425,000 was downgraded from an AAA rating to a CCC rating. As a
result of the reduction in the rating, quantitative analysis showing an increase in the default rate and decrease in prepayment rate of the investment, we recorded an other-than-temporary impairment charge of $91,000 during the second quarter of
fiscal year 2010. In the three months ended September 26, 2010, due to further decline in the investment, we recorded an additional other-than-temporary impairment charge of $62,000. In the three months ended December 26, 2010, we sold
this investment resulting in an immaterial loss from its adjusted basis.

In September 2008, Lehman Brothers Holdings Inc.
(Lehman) filed a petition under Chapter 11 of the U.S. Bankruptcy Code with the U.S. Bankruptcy Court for the Southern District of New York. As a result of Lehmans bankruptcy filing, we recorded an other-than-temporary
impairment charge of $0.6 million during fiscal year 2009. In the three months ended March 27, 2011, we sold this investment resulting in an immaterial gain from its adjusted basis.

Our long-term investment consists of our investment in Skypoint Telecom Fund II (US), L.P. (Skypoint Fund). Skypoint Fund is
a venture capital fund that invests primarily in private companies in the telecommunications and/or networking industries. We account for this non-marketable equity investment under the cost method. We periodically review and determine whether the
investment is other-than-temporarily impaired, in which case the investment is written down to its impaired value. Any decline in the value of our non-marketable investments is reported in the impairment charges on investments line in the
consolidated statements of operations.

We also have a long-term investment in TechFarm Ventures L.P. (TechFarm
Fund), another venture capital fund that invests primarily in private companies in the telecommunications and/or networking industries, to which we had contributed our total commitment to the fund of $4.0 million in capital since we became a
limited partner in May 2001. However, this investment had a carrying amount of zero as of March 27, 2011 and March 28, 2010, reflecting the net of the capital contribution and the cumulative impairment charges.

TechFarm Fund

In fiscal year 2009, we analyzed the fair value of the underlying investment in TechFarm Fund and concluded that the remaining carrying value in TechFarm Fund was other-than-temporarily impaired and
recorded an impairment charge of $0.5 million. As such, we reduced the carrying value of our investment in TechFarm Fund to zero.

##### Table of Contents

Skypoint Fund

In fiscal year 2011, we analyzed the fair value of the underlying investments of Skypoint Fund and concluded that there was no impairment
of the carrying value of our investment in the fund.

In fiscal year 2010, we analyzed the fair value of the underlying
investments of Skypoint Fund and concluded a portion of the carrying value was other-than-temporarily impaired and recorded an impairment charge of $0.2 million.

In fiscal year 2009, we analyzed the fair value of the underlying investments of Skypoint Fund and concluded a portion of the carrying value was other-than-temporarily impaired and recorded an impairment
charge of $0.7 million.

Provision for Income Taxes

Fiscal Year 2011

Our effective tax rate for fiscal year 2011 was (0.7%).
The provision for fiscal year 2011 differs from the amount computed by applying the statutory federal rate of 35%. This difference is principally due to our not benefitting from deferred tax assets as a result of increases in valuation allowances
during fiscal year 2011.

Fiscal Year 2010

Our effective tax rate for fiscal year 2010 was 1.6%. The provision for fiscal year 2010 differs from the amount computed by applying the statutory federal rate of 35%. This difference is principally due
to changes in valuation allowance, federal refundable tax credit benefits, foreign rate differential, true-up adjustment of prior year tax expense and net operating loss benefits during fiscal year 2010.

Fiscal Year 2009

Our effective tax rate for fiscal year 2009 was 0.7%. The provision for fiscal year 2009 differs from the amount computed by applying the statutory federal rate of 35%. This difference is principally due
to changes in valuation allowance and net operating loss benefits during fiscal year 2009.

Working capital changes included:

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



| |  |  | a $7.0 million increase in inventory primarily due to higher material receipts for our datacom and storage and power products in anticipation of higher
future shipments of our new products and the impact of the semiconductor industrys inventory correction; and

Investment ActivitiesIn fiscal year 2011, net cash used in investing activities includes net purchases of short-term
marketable securities of $0.9 million and $3.7 million in purchases of property, plant and equipment and intellectual property.

Financing ActivitiesIn fiscal year 2011, net cash used in financing activities reflects the $4.0 million repayment of
lease financing partially offset by $1.2 million of proceeds associated with our employee stock plans.

From time to time, we
acquire outstanding common stock in the open market to partially offset dilution from our equity award programs, to increase our return on our invested capital and to bring our cash to a more appropriate level for our company.

On August 28, 2007, we announced the approval of a share repurchase plan (2007 SRP) and authorized the repurchase of up
to $100 million of our common stock.

During fiscal years 2011 and 2010, we did not repurchase any shares of our common stock.

As of March 27, 2011, the remaining authorized amount for share repurchases under the 2007 SRP was $11.8 million. The
2007 SRP does not have a termination date. We may continue to utilize our share repurchase plan, which would reduce our cash, cash equivalents and/or short-term marketable securities available to fund future operations and to meet other liquidity
requirements.

To date, inflation has not had a significant impact on our operating results.

We anticipate that we will finance our operations with expected cash flows from operations, existing cash and investment balances, and
some combination of long-term debt and/or lease financing and additional sales of equity securities. The combination and sources of capital will be determined by management based on our needs and prevailing market conditions.

Fiscal Year 2010

Operating ActivitiesOur net loss was $28.1 million. After adjustments for non-cash items and changes in working capital, we generated $3.6 million of cash from operating activities.

Significant non-cash charges included:



| |  |  | Depreciation and amortization expenses of $20.8 million;
| | - |  | --------------------------------------------------------



| |  |  | Stock-based compensation expense of $6.0 million; and

OFF-BALANCE SHEET ARRANGEMENTS

As of March 27, 2011, we had not utilized special purpose entities to facilitate off-balance sheet financing arrangements. However, we have, in the normal course of business, entered into agreements
which impose warranty obligations with respect to our products or which obligate us to provide indemnification of varying scope and terms to customers, vendors, lessors and business partners, our directors and executive officers, purchasers of
assets or subsidiaries, and other parties with respect to certain matters. These arrangements may

##### Table of Contents

constitute off-balance sheet transactions as defined in Section 303(a)(4) of Regulation S-K. Please see Notes to the Consolidated Financial Statements, Note
16Commitments and Contingencies for further discussion of our product warranty liabilities and indemnification obligations.

As discussed in Notes to the Consolidated Financial Statements, Note 16Commitments and Contingencies, during the normal course of business, we make certain indemnities and
commitments under which we may be required to make payments in relation to certain transactions. These indemnities include non-infringement of patents and intellectual property, indemnities to our customers in connection with the delivery, design,
manufacture and sale of our products, indemnities to our directors and officers in connection with legal proceedings, indemnities to various lessors in connection with facility leases for certain claims arising from such facility or lease, and
indemnities to other parties to certain acquisition agreements. The duration of these indemnities and commitments varies, and in certain cases, is indefinite. We believe that substantially all of our indemnities and commitments provide for
limitations on the maximum potential future payments we could be obligated to make. However, we are unable to estimate the maximum amount of liability related to our indemnities and commitments because such liabilities are contingent upon the
occurrence of events which are not reasonably determinable. We believe that any liability for these indemnities and commitments would not be material to our accompanying consolidated financial statements.

|ITEM 7A. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|-------- | ----------------------------------------------------------

Foreign Currency Fluctuations.We are exposed to foreign currency fluctuations primarily through our foreign operations. This exposure is the result of foreign operating
expenses being denominated in foreign currency. Operational currency requirements are typically forecasted for a one-month period. If there is a need to hedge this risk, we may enter into transactions to purchase currency in the open market or enter
into forward currency exchange contracts.

If our foreign operations forecasts are overstated or understated during periods of
currency volatility, we could experience unanticipated currency gains or losses. For fiscal years 2011 and 2010, we did not have significant foreign currency denominated net assets or net liabilities positions, and had no foreign currency contracts
outstanding.

Investment Risk and Interest Rate Sensitivity.    We maintain investment portfolio
holdings of various issuers, types, and maturity dates with various banks and investment banking institutions. The market value of these investments on any given day during the investment term may vary as a result of market interest rate
fluctuations. Our investment portfolio consisted of cash equivalents, money market funds and fixed income securities of $193.4 million as of March 27, 2011 and $206.2 million as of March 28, 2010. These securities, like all fixed income
instruments, are subject to interest rate risk and will vary in value as market interest rates fluctuate. If market interest rates were to increase or decline immediately and uniformly by less than 10% from levels as of March 27, 2011, the
increase or decline in the fair value of the portfolio would not be material. At March 27, 2011, the difference between the fair value and the underlying cost of the investments portfolio was a net unrealized gain of $0.5 million.

Our short-term investments are classified as available-for-sale securities and the cost of securities sold is based on the
specific identification method. At March 27, 2011, short-term investments consisted of asset and mortgage-backed securities, corporate bonds and government agency securities totaling $186.0 million.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Exar Corporation:

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, stockholders
equity and comprehensive income (loss), and of cash flows present fairly, in all material respects, the financial position of Exar Corporation and its subsidiaries at March 27, 2011 and March 28, 2010, and the results of their operations
and their cash flows for each of the three years in the period ended March 27, 2011 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material
respects, effective internal control over financial reporting as of March 27, 2011, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission
(COSO). The Companys management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting,
included in Managements Annual Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on these financial statements and on the Companys internal control over financial
reporting based on our integrated 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 audits to obtain reasonable
assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on
a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit
of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of
internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A companys internal control over financial reporting is a process designed 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 (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) 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 (iii) 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 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.

1.    DESCRIPTION OF BUSINESS

Exar Corporation was incorporated in California in 1971 and
reincorporated in Delaware in 1991. Exar Corporation and its subsidiaries (Exar or we) is a fabless semiconductor company that designs, sub-contracts manufacturing and sells highly differentiated silicon, software and
subsystem solutions for industrial, telecom, networking and storage applications.

On March 16, 2010, we completed the
acquisition of Neterion, Inc. (Neterion), a supplier of 10 Gigabit Ethernet (GbE) controller silicon and card solutions optimized for virtualized data centers located in Sunnyvale, California.

On June 17, 2009, we completed the acquisition of Galazar Networks, Inc. (Galazar), a fabless semiconductor company
focused on carrier grade transport over telecom networks based in Ottawa, Ontario, Canada. Galazars product portfolio addressed transport of a wide range of datacom and telecom services including Ethernet, SAN, TDM and video over SONET/SDH,
PDH and OTN networks.

On April 3, 2009, we completed the acquisition of hi/fn, inc. (Hifn), a provider of
network-and storage-security and data reduction products located in Los Gatos, California.

Certain reclassifications have
been made to the prior year consolidated financial statements to conform to the current years presentation. Such reclassification had no effect on previously reported results of operations or stockholders equity.

NOTE 2.    ACCOUNTING POLICIES

Basis of PresentationOur fiscal years consist of 52 or 53 weeks. In a 52-week year, each fiscal quarter consists of 13 weeks. The three fiscal years 2011, 2010 and 2009 are each
comprised of 52-weeks. Fiscal year 2012 will consist of 53 weeks.

Principles of ConsolidationThe
consolidated financial statements include the accounts of Exar Corporation and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated.

Use of Management EstimatesThe preparation of consolidated financial statements in conformity with generally accepted accounting principles in the United States requires management to
make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates, including
(1) revenue recognition; (2) valuation of inventories; (3) income taxes; (4) stock-based compensation; (5) goodwill; and (6) long-lived assets. Actual results could differ from these estimates and material effects on
operating results and financial position may result.

Business CombinationsThe estimated
fair value of acquired assets and assumed liabilities and the results of operations of acquired businesses are included in our consolidated financial statements from the effective date of the purchase. The total purchase price is allocated to the
estimated fair value of assets acquired and liabilities assumed. (See Note 3Business Combinations.)

Cash and Cash EquivalentsWe consider all highly liquid debt securities and investments with maturities of 90 days or
less from the date of purchase to be cash and cash equivalents. Cash and cash equivalents also consist of cash on deposit with banks and money market funds.

FISCAL YEARS ENDED MARCH 27, 2011, MARCH 28, 2010, AND MARCH 29, 2009



InventoriesInventories are recorded at the lower of cost or market,
determined on a first-in, first-out basis. Cost is computed using the standard cost, which approximates average actual cost. Inventory is written down when conditions indicate that the selling price could be less than cost due to physical
deterioration, obsolescence, changes in price levels, or other causes. The write-down of excess inventories is generally based on inventory levels in excess of twelve months of demand, as judged by management, for each specific product.

Property, Plant and EquipmentProperty, plant and equipment, including assets held under capital leases and leasehold
improvements, are stated at cost less accumulated depreciation and amortization. Depreciation for machinery and equipment is computed using the straight-line method over the estimated useful lives of the assets, which ranges from three to ten years.
Buildings are depreciated using the straight-line method over an estimated useful life of 30 years. Assets held under capital leases and leasehold improvements are amortized over the shorter of the terms of the leases or their estimated useful
lives. Land is not depreciated.

Non-Marketable Equity SecuritiesNon-marketable equity investments are
accounted for at historical cost and are presented on our consolidated balance sheets within other non-current assets.

Other-Than-Temporary ImpairmentAll of our marketable and non-marketable investments are subject to periodic
impairment reviews. Investments are considered to be impaired when a decline in fair value is judged to be other-than-temporary, as follows:

Marketable investmentsWhen the resulting fair value is significantly below cost basis and/or the significant decline has lasted for an extended period of time, we perform an evaluation to
determine whether the marketable equity security is other than temporarily impaired. The evaluation that we use to determine whether a marketable equity security is other than temporarily impaired is based on the specific facts and circumstances
present at the time of assessment, which include significant quantitative and qualitative assessments and estimates regarding credit ratings, collateralized support, the length of time and significance of a securitys loss position and intent
and ability to hold a security to maturity or forecasted recovery. Other-than-temporary declines in value of our investments are reported in the impairment charges on investments line in the consolidated statements of operations.

Non-marketable equity investmentsWhen events or circumstances are identified that would likely have a significant adverse
effect on the fair value of the investment and the fair value is significantly below cost basis and/or the significant decline has lasted for an extended period of time, we perform an impairment analysis. The indicators that we use to identify those
events and circumstances include:



| |  |  | the investment managers evaluation;
| | - |  | ------------------------------------



| |  |  | the investees revenue and earnings trends relative to predefined milestones and overall business prospects;
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | the technological feasibility of the investees products and technologies;
| | - |  | --------------------------------------------------------------------------



| |  |  | the general market conditions in the investees industry; and
| | - |  | -------------------------------------------------------------



| |  |  | the investees liquidity, debt ratios and the rate at which the investee is using cash.
| | - |  | ---------------------------------------------------------------------------------------

Investments identified as having an indicator of impairment are subject to further analysis to determine if the investment is other than
temporarily impaired, and if so, the investment is written down to its impaired value. When an investee is not considered viable from a financial or technological point of view, the entire investment is written down. Impairment of non-marketable
equity investments is recorded in the impairment charges on investments line in the consolidated statements of operations.

GoodwillGoodwill represents the excess of the purchase price over
the fair value of the net tangible and identifiable intangible assets acquired in a business combination. We evaluate goodwill for impairment on an annual basis or whenever events and changes in circumstances suggest that the carrying amount may not
be recoverable. Impairment of goodwill is tested at the reporting unit level by comparing the reporting units carrying amount, including goodwill, to the fair value of the reporting unit. The fair values of the reporting units are estimated
using a combination of the income, or discounted cash flows, approach and the market approach, which utilize comparable companies data. If the carrying amount of the reporting unit exceeds its fair value, goodwill is considered impaired and a
second step is performed to measure the amount of impairment loss, if any. Because we have one reporting unit, we utilize the entity-wide approach to assess goodwill for impairment. During our annual goodwill impairment analysis in the fourth
quarters of fiscal year 2011 and fiscal year 2010, fair value exceeded carrying value and no impairment was recorded.

In the
third quarter of fiscal year 2009, the rapid and severe deterioration of worldwide economic conditions affected our industry and led customers to scale down their levels of production. As a result of these impairment indicators, we considered the
potential impairment of goodwill. Indicators that required us to perform an interim impairment review consisted of further weakening in new orders from our customers throughout the third quarter and into the fourth quarter of fiscal year 2009, as
well as the uncertainty of the magnitude and duration of the recession as evidenced by industry analysts expectations that demand for semiconductors would remain weak until economic conditions improve. In addition, we experienced a significant
decline in our stock price that reduced our market capitalization below our net asset carrying value for an extended period of time. We performed an interim goodwill impairment analysis and recorded a $46.2 million impairment loss that was included
in the impairment of intangible assets and goodwill line in the consolidated statements of operations. (See Note 9Goodwill and Intangible Assets).

Long-Lived AssetsWe assess the impairment of long-lived assets when events or changes in circumstances indicate that the carrying value of the assets or the asset grouping may not be
recoverable. Factors that we consider in deciding when to perform an impairment review include significant negative industry or economic trends, and significant changes or planned changes in our use of the assets. These factors can also be referred
to as triggering events. We measure the recoverability of assets that will continue to be used in our operations by comparing the carrying value of the asset grouping to our estimate of the related total future undiscounted net cash flows. If an
asset groupings carrying value is not recoverable through the related undiscounted cash flows, the asset grouping is considered to be impaired. The impairment is measured by comparing the difference between the asset groupings carrying
value and its fair value. Long-lived assets such as goodwill; intangible assets; and property, plant and equipment are considered non-financial assets, and are recorded at fair value only if an impairment charge is recognized.

Impairments of long-lived assets are determined for groups of assets related to the lowest level of identifiable independent cash flows.
We operate with one asset group on an enterprise basis. As a result, we believe the lowest identifiable cash flows reside at the enterprise level.

When we determine that the useful lives of assets are shorter than we had originally estimated, we accelerate the rate of depreciation and/or amortization over the assets new, shorter useful lives.

Substantially all of our property, plant and equipment and other long-lived assets are located in the United States.

In-process research and developmentIn-process research and development (IPR&D) assets are
considered indefinite-lived intangible assets and are not subject to amortization until their useful life is

determined. IPR&D assets must be tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test
consists of a comparison of the fair value of the IPR&D assets with their carrying values. If the carrying amount of the IPR&D asset exceeds its fair value, an impairment loss must be recognized in an amount equal to that excess. After an
impairment loss is recognized, the adjusted carrying amount of the IPR&D assets will be their new accounting basis. Subsequent reversal of a previously recognized impairment loss is prohibited. The initial determination and subsequent evaluation
for impairment of the IPR&D asset requires management to make significant judgments and estimates. Once an IPR&D project has been completed, the useful life of the IPR&D asset is determined and amortized accordingly. If the IPR&D
asset is abandoned, the remaining carrying value is written off.

Income TaxesDeferred 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, operating losses and tax credit carryforwards. Valuation allowances are provided if it is more likely than not that some or all of the deferred tax assets will not be realized.

Revenue RecognitionWe recognize revenue in accordance with Financial Accounting Standards
Board (FASB) authoritative guidance for Revenue Recognition. Four basic criteria must be met before revenue can be recognized: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have
been rendered; (3) the price is fixed or determinable; and (4) collectability is reasonably assured.

We derive
revenue principally from the sale of our products to distributors and to OEMs or their contract manufacturers. Our delivery terms are primarily FOB shipping point, at which time title and all risks of ownership are transferred to the customer.

Non-distributorsFor non-distributors, revenue is recognized when title to the product is transferred to
the customer, which occurs upon shipment or delivery, depending upon the terms of the customer order, provided that persuasive evidence of a sales arrangement exists, the price is fixed or determinable, collection of the resulting receivables is
reasonably assured, there are no customer acceptance requirements and there are no remaining significant obligations. Provisions for returns and allowances for non-distributor customers are provided at the time product sales are recognized. An
allowance for sales returns and allowances for non-distributor customers are recorded based on historical experience or specific identification of an event necessitating an allowance.

DistributorsAgreements with our two primary distributors permit the return of 3% to 5% of their purchases during the
preceding quarter for purposes of stock rotation. For one of these distributors, a scrap allowance of 2% of the preceding quarters purchases is permitted. We also provide discounts to certain distributors based on volume of product they sell
for a specific product with a specific volume range for a given customer over a period not to exceed one year.

We recognize
revenue from each of our distributors using either of the following bases. Once adopted, the basis for revenue recognition for a distributor is maintained unless there is a change in circumstances indicating the basis for revenue recognition for
that distributor is no longer appropriate.



| |  |  | Sell-in BasisRevenue is recognized upon shipment if we conclude we meet the same criteria as for non-distributors and we can
reasonably estimate the credits for returns, pricing allowances and/or other concessions. We record an estimated allowance, at the time of shipment, based upon historical patterns of returns, pricing allowances and other concessions (i.e.,
sell-in basis).

| |  |  | Sell-through BasisRevenue and the related costs of sales are deferred until the resale to the end customer if we grant more
than limited rights of return, pricing allowances and/or other concessions or if we cannot reasonably estimate the level of returns and credits issuable (i.e., sell-through basis). Under the sell-through basis, accounts receivable are
recognized and inventory is relieved upon shipment to the distributor as title to the inventory is transferred upon shipment, at which point we have a legally enforceable right to collection under normal terms. The associated sales and cost of sales
are deferred and are included in deferred income and allowance on sales to distributors in the consolidated balance sheet. When the related product is sold by our distributors to their end customers, at which time the ultimate price we receive is
known, we recognize previously deferred income as sales and cost of sales.

Sell-through revenue recognition
is highly dependent on receiving pertinent and accurate data from our distributors in a timely fashion. Distributors provide us periodic data regarding the product, price, quantity, and end customer when products are resold as well as the quantities
of our products they still have in stock. We must use estimates and apply judgments to reconcile distributors reported inventories to their activities. Any error in our judgment could lead to inaccurate reporting of our net sales, gross
profit, deferred income and allowances on sales to distributors and net income.

Software became an element of our revenue
upon the acquisition of Hifn in April 2009. To date, software revenue has been an immaterial portion of our net sales.

Research and Development ExpensesResearch and development costs consist primarily of salaries, employee benefits,
mask tooling costs, depreciation, amortization, overhead, outside contractors, facility expenses, and non-recurring engineering fees. Expenditures for research and development are charged to expense as incurred. In accordance with FASB authoritative
guidance for the costs of computer software to be sold, leased or otherwise marketed, certain software development costs are capitalized after technological feasibility has been established. The period from achievement of technological feasibility,
which we define as the establishment of a working model, until the general availability of such software to customers, has been short, and therefore software development costs qualifying for capitalization have been insignificant. Accordingly, we
have not capitalized any software development costs in fiscal years 2011, 2010 and 2009.

In connection with the Hifn
acquisition in April 2009, we assumed a contractual agreement under which certain research and development costs are eligible for reimbursement. Amounts collected under this arrangement are offset against research and development expense. During
fiscal year 2011 and fiscal year 2010, we received $5.0 million and $4.6 million, respectively, for work performed, which was recorded as an offset to research and development expenses.

Advertising ExpensesWe expense advertising costs as incurred. Advertising expenses for fiscal years 2011, 2010 and
2009 were not material.

Comprehensive Income (Loss)Comprehensive income (loss) includes charges or
credits to equity related to changes in unrealized gains or losses on marketable securities, net of taxes. Comprehensive income (loss) for fiscal years 2011, 2010 and 2009 has been disclosed within the consolidated statements of stockholders
equity and comprehensive income (loss).

Foreign CurrencyThe accounts of foreign subsidiaries are
remeasured to U.S. dollars for financial reporting purposes by using the U.S. dollar as the functional currency and exchange gains and losses are reported in income and expenses. These currency gains or losses are reported in interest income and
other, net in the consolidated statements of operations. Monetary balance sheet accounts are remeasured using the current

exchange rate in effect at the balance sheet date. For non-monetary items, the accounts are measured at the historical exchange rate. Revenues and expenses are remeasured at the average exchange
rates for the period. Foreign currency transaction losses were not material for fiscal years 2011, 2010 and 2009.

Concentration of Credit Risk and Significant CustomersFinancial instruments potentially subjecting us to
concentrations of credit risk consist primarily of cash, cash equivalents, short-term marketable securities, accounts receivable and long-term investments. The majority of our sales are derived from distributors and manufacturers in the
communications, industrial, storage and computer industries. We perform ongoing credit evaluations of our customers and generally do not require collateral for sales on credit. We maintain allowances for potential credit losses, and such losses have
been within managements expectations. Charges to bad debt expense were insignificant for fiscal years 2011, 2010 and 2009. Our policy is to invest our cash, cash equivalents and short-term marketable securities with high credit quality
financial institutions and limit the amounts invested with any one financial institution or in any type of financial instrument. We do not hold or issue financial instruments for trading purposes.

We sell our products to distributors and OEMs throughout the world. Future Electronics, Inc. (Future), a related party, was
and continues to be our largest distributor. Future, on a worldwide basis, represented 30%, 28% and 35% of net sales in fiscal years 2011, 2010 and 2009, respectively. No other OEM customer or distributor accounted for 10% or more of our net sales
in fiscal year 2011, 2010 or 2009.

Concentration of Other RisksThe majority of our products are currently
fabricated at Globalfoundries Singapore Pte. Ltd. (f.k.a. Chartered Semiconductor Manufacturing Ltd.), Episil Technologies Inc. (Episil) in Taiwan, and Hangzhou Silan Microelectronics Co. Ltd. and Hangzhou Silan Integrated Circuit Co.
Ltd. (collectively Silan) in the Peoples Republic of China (PRC), and are assembled and tested by other third-party subcontractors located in Asia. A significant disruption in the operations of one or more of these
subcontractors would impact the production of our products for a substantial period of time which could have a material adverse effect on our business, financial condition and results of operations.

Fair Value of Financial InstrumentsWe estimate the fair value of our financial instruments by using available market
information and valuation methodologies considered to be appropriate. However, considerable judgment is required in interpreting market data to develop the estimates of fair value. The use of different market assumptions and/or estimation
methodologies could have a material effect on estimated fair value amounts. The estimated fair value of our carrying values of cash and cash equivalents, short-term marketable securities, accounts receivable, accounts payable and accrued liabilities
at March 27, 2011, March 28, 2010 and March 29, 2009 was not materially different from the carrying values presented in the consolidated balance sheets due to the relatively short periods to maturity of the instruments.

Stock-Based CompensationThe estimated fair value of the equity-based awards, less expected forfeitures,
is amortized over the awards vesting period on a straight-line basis. Determining the fair value of stock-based awards at the grant date requires considerable judgment, including estimating expected volatility, forfeiture rate, expected term
and risk-free interest rate. If factors change and we employ different assumptions, stock-based compensation expense may differ significantly from what we have recorded in the prior years. In addition, we follow the with-and-without
intra-period allocation approach in our tax attribute calculations.

Recent Accounting Pronouncements

In December 2010, the FASB issued an update to its existing guidance on goodwill and other intangible assets. This guidance modifies Step
1 of the goodwill impairment test for reporting units with zero or negative carrying amounts. For those reporting units, an entity is required to perform Step 2 of the goodwill impairment test if there are qualitative factors indicating that it is
more likely than not that a goodwill impairment exists. The qualitative factors are consistent with the existing guidance which requires goodwill of a reporting unit to be tested for impairment between annual tests if an event occurs or
circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2010,
which is beginning March 28, 2011 for us. We are currently evaluating the impact of implementing this guidance on our business, financial condition and results of operations.

In January 2010, the FASB Emerging Issues Task Force issued new authoritative guidance addressing certain measurements and disclosures
about purchases, sales, issuances, and settlements in Level 3 fair value measurements. We are currently evaluating the impact of implementing the disclosures about purchases, sales, issuances, and settlements in Level 3 fair value measurements on
our financial position and result of operations, which are effective for fiscal years beginning after December 15, 2010 and for interim periods within those fiscal years. Historically, we have not held investments with Level 3 fair value
measurements.

NOTE 3.    BUSINESS COMBINATIONS

We periodically evaluate potential strategic acquisitions to build upon our existing library of intellectual property, human capital and
engineering talent, in order to expand our capabilities in the areas in which we operate or to acquire complementary businesses.

We account for each business combination by applying the acquisition method, which requires (i) identifying the acquiree; (ii) determining the acquisition date; (iii) recognizing and
measuring the identifiable assets acquired, the liabilities assumed, and any noncontrolling interest of Exar in the acquiree at their acquisition date fair value; and (iv) recognizing and measuring goodwill or a gain from a bargain purchase.

Assets acquired and liabilities assumed in a business combination that arise from contingencies are recognized at fair value
on the acquisition date if fair value can be determined during the measurement period. If fair value cannot be determined, we typically account for the acquired contingencies using existing guidance for a reasonable estimate.

To establish fair value, we measure the price that would be received to sell an asset or paid to transfer a liability in an ordinary
transaction between market participants. The measurement assumes the highest and best use of the asset by the market participants that would maximize the value of the asset or the group of assets within which the asset would be used at the
measurement date, even if the intended use of the asset is different.

Goodwill is measured and recorded as the amount by
which the consideration transferred, generally at the acquisition date fair value, exceeds the acquisition date fair value of identifiable assets acquired, the liabilities assumed, and any non-controlling interest of Exar in the acquiree. To the
contrary, if the acquisition date fair value of identifiable assets acquired, the liabilities assumed, and any non-controlling interest of Exar in the acquiree exceeds the consideration transferred, it is considered a bargain purchase and we would
recognize the resulting gain in earnings on the acquisition date.

IPR&D assets are considered an indefinite-lived intangible asset and are not
subject to amortization until its useful life is determined to be no longer indefinite. IPR&D assets must be tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. The
impairment test consists of a comparison of the fair value of the IPR&D asset with its carrying amount. If the carrying amount of the IPR&D asset exceeds its fair value, an impairment loss must be recognized in an amount equal to that
excess. After an impairment loss is recognized, the adjusted carrying amount of the IPR&D assets will be its new accounting basis. Subsequent reversal of a previously recognized impairment loss is prohibited. The initial determination and
subsequent evaluation for impairment of the IPR&D asset requires management to make significant judgments and estimates. Once the IPR&D projects have been completed, the useful life of the IPR&D asset is determined and amortized
accordingly. If the IPR&D asset is abandoned, the remaining carrying value is written off.

Acquisition-related costs,
including finders fees, advisory, legal, accounting, valuation and other professional or consulting fees are accounted for as expenses in the periods in which the costs are incurred and the services are received, with the exception that the
costs to issue debt or equity securities are recognized in accordance with other applicable GAAP.

Acquisition of Neterion

On March 16, 2010, we completed the acquisition of Neterion, Inc. (Neterion), a supplier of 10 GbE controller silicon and
card solutions optimized for virtualized data centers based in Sunnyvale, California. Neterions results of operations and estimated fair value of assets acquired and liabilities assumed were included in our consolidated financial statements
beginning March 17, 2010.

Consideration

We paid approximately $2.3 million in cash for Neterion, representing the fair value of total consideration transferred.

Acquisition-Related Costs

Acquisition-related costs relating to Neterion,
which are included in the selling, general and administrative line on the consolidated statement of operations, were not material in fiscal year 2011. In fiscal year 2010, we recorded $0.5 million in acquisition-related costs relating to Neterion.

Restructuring Costs

For disclosure regarding restructuring costs, see Note 7Restructuring & Other contained herein.

Purchase Price Allocation

The allocation of the purchase price to
Neterions tangible and identifiable intangible assets acquired and liabilities assumed was based on their estimated fair values at the date of acquisition.

The excess of the purchase price over the tangible and identifiable intangible assets acquired and liabilities assumed has been allocated to goodwill. The $464,000 in goodwill resulted primarily from our
expected synergies from the integration of Neterions technology into our product offerings. Goodwill is not deductible for tax purposes.

We allocated the purchase price using the established valuation techniques described below.

InventoriesThe value allocated to inventories reflects the estimated fair value of the acquired inventory based
on the expected sales price of the inventory, less reasonable selling margin. The estimated fair value of raw materials is generally equal to their book value, due to the fact that raw materials have not been used to develop any finished goods or
work-in-progress and therefore, there is no value added to the raw materials.

Intangible assetsThe fair values of existing technology, patents/core
technology, in-process research and development, customer relationships, tradenames/trademarks, non-compete agreements and order backlog were determined using the income approach, which discounted expected future cash flows to present value, taking
into account multiple factors including, but not limited to, the stage of completion, estimated costs to complete, utilization of patents/core technology, the risks related to successful completion, and the markets served. The cash flows were
discounted at rates ranging from 4% to 33%. The discount rate used to value the existing intangible assets was 20%.

Acquired In-Process Research and DevelopmentThe IPR&D project underway at Neterion at the acquisition date related to
the X3500 product series and as of such acquisition date had incurred approximately $2.9 million in expense. This project was abandoned in March 2011 when we exited the 10 GbE market, resulting in a charge of $0.8 million in fiscal year 2011. (See
Note 9Goodwill and Intangible Assets).

Acquisition of Galazar

On June 17, 2009, we completed the acquisition of Galazar Networks, Inc. (Galazar), a fabless semiconductor company
focused on carrier grade transport over telecom networks based in Ottawa, Ontario, Canada. Galazars product portfolio addressed transport of a wide range of datacom and telecom services including Ethernet, SAN, TDM and video over SONET/SDH,
PDH and OTN networks. Galazars results of operations and estimated fair value of assets acquired and liabilities assumed were included in our consolidated financial statements beginning June 18, 2009.

Consideration

We paid approximately $5.0 million in cash for Galazar, representing the fair value of total consideration transferred. This amount included approximately $1.0 million contingent consideration that, for
the purposes of valuation, was assigned a 95% probability or a fair value of $0.95 million. This payment was contingent on Galazar achieving a project milestone within a twelve-month period following the close of the transaction. This milestone was
met during the three months ended December 27, 2009 and $1.0 million was paid in cash. The additional $50,000 was expensed and included in the research and development line on the consolidated statement of operations for fiscal year 2010.

Acquisition-Related Costs

Acquisition-related costs, or deal costs, relating to Galazar are included in the selling, general and administrative line on the consolidated statement of operations. No acquisition-related costs
relating to Galazar were incurred during fiscal year 2011. In fiscal year 2010, we recorded $0.9 million in acquisition-related costs relating to Galazar.

Purchase Price Allocation

The allocation of the purchase price to
Galazars tangible and identifiable intangible assets acquired and liabilities assumed was based on their estimated fair values at the date of acquisition.

The excess of the purchase price over the tangible and identifiable intangible assets acquired and liabilities assumed has been allocated to goodwill. The $372,000 in goodwill resulted primarily from our
expected synergies from the integration of Galazars technology into our product offerings. Goodwill is not deductible for tax purposes.

Acquired In-Process Research and DevelopmentThe IPR&D project underway
at Galazar at the acquisition date relates to the MXP2 product and as of such acquisition date had incurred approximately $2.3 million in expense. The total research and development expense expected to be incurred to complete the project is
estimated at $12.0 million, based on the project development timeline and resource requirements, and is expected to be completed by February 2012. The percentage of completion for the project was estimated at 51% at the acquisition date.

Acquisition of Hifn

On
April 3, 2009, we completed the acquisition of hi/fn, inc. (Hifn), a provider of network-and storage-security and data reduction products located in Los Gatos, California. Hifns results of operations and estimated fair value
of assets acquired and liabilities assumed were included in our consolidated financial statements beginning April 4, 2009.

Consideration

The following table summarizes the consideration paid for Hifn, representing the fair value of total consideration transferred (in thousands):



|                         |  |         |        | 
|------------------------ |  | ------- | ------ | 
|                         |  | Amounts |       
|Cash                     |  | $       | 56,825 | 
|Equity instruments       |  |         | 2,784  | 
|                         |  |         |        | 
|Total consideration paid |  | $       | 59,609 | 
|                         |  |         |        | 

The $2.8 million estimated fair value for equity instruments represented approximately 429,600 shares of
Exars common stock, valued at $6.48 per share, the closing price reported on The NASDAQ Global Market on April 3, 2009 (the acquisition date).

Acquisition-Related Costs

Acquisition-related costs, or deal costs,
relating to Hifn are included in the selling, general and administrative line on the consolidated statement of operations. Acquisition-related costs incurred in fiscal year 2011 relating to Hifn were not material. In fiscal year 2010, we incurred
$3.8 million of acquisition-related costs relating to Hifn.

Purchase Price Allocation

The allocation of the purchase price to Hifns tangible and identifiable intangible assets acquired and liabilities assumed was based
on their estimated fair values at the date of acquisition. Subsequent to the acquisition, we recorded $1.0 million in restructuring expenses relating to Hifn for fiscal year 2010, relating to severance and a building lease obligation in Los Gatos,
California. Severance costs relating to Hifn incurred during fiscal year 2011 were immaterial.

The excess of the purchase
price over the tangible and identifiable intangible assets acquired and liabilities assumed has been allocated to goodwill. The $2.2 million in goodwill resulted primarily from our expected future product sales synergies from combining Hifns
products with our product offerings. Goodwill is not deductible for tax purposes.

We allocated the purchase price using the established valuation techniques as described
below.

InventoriesInventories acquired in connection with the Hifn acquisition were finished goods. The value
allocated to inventories reflects the estimated fair value of the acquired inventory based on the expected sales price of the inventory, less reasonable selling margin.

Property, plant and equipmentThe basis used for our analysis is the fair value in continued use, which is expressed in terms of the price a willing and informed buyer would pay contemplating
continued use as part of the assets in place for the purpose for which they were designed, engineered, installed, fabricated and erected.

Intangible assetsThe fair value of existing technology, patents/core technology, in-process research and development, customer relationships, tradenames/trademarks, order backlog and research
and development reimbursement contract were determined using the income approach, which discounted expected future cash flows to present value, taking into account multiple factors including, but not limited to, the stage of completion, estimated
costs to complete, utilization of patents and core technology, the risks related to successful completion, and the markets served. The cash flows were discounted at rates ranging from 5% to 30%. The discount rate used to value the existing
intangible assets was 14%.

Acquired In-Process Research and DevelopmentThe IPR&D projects underway at Hifn
at the acquisition date were in the security processors and flow through product families, each consisting of one project, and as of such acquisition date Hifn had incurred approximately $2.6 million and $1.1 million in costs related to those
projects, respectively. The percentage of completion for these projects, at the date of acquisition, was 90% and 30%, respectively. The total research and development expenditures expected to be incurred to complete the security processors and flow
through projects were approximately $2.1 million and $0.7 million, respectively, based on project development timelines and resource requirements. The IPR&D projects for flow through and security processors were completed in January 2010 and
July 2010, respectively, and are in production. The fair value, at date of acquisition, for both IPR&D projects, is being amortized over an estimated useful life of five years.

NOTE 5.    CASH, CASH EQUIVALENTS AND SHORT-TERM MARKETABLE SECURITIES

Fair Value of Financial Instruments

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly
transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. GAAP describes a fair value hierarchy based on
three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value as follows:

Level 1Quoted prices in active markets for identical assets or liabilities.

Level 2Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or
liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the
assets or liabilities.

Our marketable securities include municipal securities, commercial paper, asset-backed
and mortgage-backed securities, corporate bonds and U.S. government securities. We classify investments as available-for-sale at the time of purchase and re-evaluate such designation as of each balance sheet date. We amortize premiums and accrete
discounts to interest income over the life of the investment. Our available-for-sale securities, which we intend to sell as necessary to meet our liquidity requirements, are classified as cash equivalents if the maturity date is 90 days or less from
the date of purchase and as short-term marketable securities if the maturity date is greater than 90 days from the date of purchase.

All marketable securities are reported at fair value based on the estimated or quoted market prices as of each balance sheet date, with unrealized gains or losses, net of tax effect, recorded in
accumulated other comprehensive income (loss) within stockholders equity except those unrealized losses that are deemed to be other than temporary which are reflected in the impairment charges on investments line on the consolidated statements
of operations.

Realized gains or losses on the sale of marketable securities are determined by the specific identification
method and are reflected in the interest income and other, net line on the consolidated statements of operations.

Our net
realized gains (losses) on marketable securities were as follows for the periods indicated (in thousands):

|(1) | Gross of tax impact
|--- | -------------------

The
asset-backed securities are comprised primarily of premium tranches of auto loans and credit card receivables, while our mortgage-backed securities are primarily from Federal agencies. We do not own auction rate securities nor do we own securities
that are classified as subprime. As of the date of this Annual Report, we have sufficient liquidity and do not intend to sell these securities to fund normal operations nor realize any significant losses in the short term; however, these securities
are available for use, if needed, for current operations.

Management determines the appropriate classification of cash
equivalents or short-term marketable securities at the time of purchase and reevaluates such classification as of each balance sheet date. The investments are adjusted for amortization of premiums and accretion of discounts to maturity and such
accretion/amortization is included in the interest income and other, net line in the consolidated statement of operations. Cash equivalents and short-term marketable securities are reported at fair value with the related unrealized gains and losses
included in the accumulated other comprehensive income (loss) line in the consolidated balance sheets. As of March 27, 2011, there was approximately $0.3 million of net unrealized losses including tax expense from our level 1 and level 2
investments.

We periodically review our investments in unrealized loss positions for other-than-temporary impairments. This
evaluation includes, but is not limited to, significant quantitative and qualitative assessments and estimates regarding credit ratings, collateralized support, the length of time and significance of a securitys loss position, our intent to
not sell the security, and whether it is more likely than not that we will not have to sell the security before recovery of its cost basis. Other-than-temporary declines in value of our investments are reported in the impairment charges on
investments line in the consolidated statements of operations.

In fiscal year 2010, an investment in GSAA Home Equity with a
cost of $425,000 was downgraded from a AAA rating to a CCC rating. As a result of the reduction in the rating, quantitative analysis showing an increase in the default rate and decrease in prepayment rate of the investment, we recorded an
other-than-temporary impairment charge of $91,000 during the second quarter of fiscal year 2010. In the three months ended September 26, 2010, due to further decline in the investment, we recorded an additional other-than-temporary impairment
charge of $62,000. In the three months ended December 26, 2010, we sold this investment resulting in an immaterial loss from its adjusted basis.

In September 2008, Lehman Brothers Holdings Inc. (Lehman) filed a petition under Chapter 11 of the U.S. Bankruptcy Code with the U.S. Bankruptcy Court for the Southern District of New
York. As a result of Lehmans bankruptcy filing, we recorded an other-than-temporary impairment charge of $0.6 million during fiscal year 2009. In the three months ended March 27, 2011, we sold this investment resulting in an immaterial
gain from its adjusted basis.

NOTE 7.    RESTRUCTURING & OTHER

During the fourth quarter of fiscal year 2011, we decided to exit the data center virtualization market, and, in connection therewith, to stop development of our 10GbE network interface cards. We
determined that the current economic and market environment did not provide the potential to deliver acceptable returns on the required investments in these products. As a result, in the fourth quarter of fiscal year 2011 we abandoned all related
in-process research and development. In addition, we began to actively market for sale the related assets of our 10GbE technology, consisting primarily of underlying existing and core technology intangible assets. Charges related to this decision in
the fourth quarter of fiscal year 2011 totaled approximately $11.1 million and included $7.5 million for the impairment of intangible assets, which is included within the impairment of intangible assets and goodwill line in our consolidated
statements of operations, $2.1 million for the write-off of inventory, which is included within the cost of sales line in our consolidated statements of operations, and $1.2 million in severance related costs, which is included primarily within the
research and development line in our consolidated statements of operations. The majority of the severance related costs were paid out in fiscal year 2011.

The intangible asset impairment charge of $7.5 million consists of $0.8 million to the write-off abandoned IPR&D acquired in the Neterion acquisition and $6.7 million to write-down the carrying value
of intangible assets that are held for sale to $0.2 million at March 27, 2011, which represents their estimated fair value less costs to sell based on third-party bids received to date.

During the quarter ended December 26, 2010, we vacated our facility in Framingham, Massachusetts and recorded a restructuring
reserve of $134,000 for the remaining payments owed on this site. We expect this balance to be paid by November 2011 when the lease expires.

In connection with the Neterion acquisition in March 2010, we assumed a lease obligation for a facility in Sunnyvale, California. We vacated the facility in May 2010 and recorded a restructuring reserve
of approximately $234,000, during the quarter ended June 27, 2010, for the remaining payments due on this site. This balance is expected to be paid by August 2011 when the lease expires.

In connection with the acquisition of Sipex Corporation (Sipex) in August 2007, our management approved and initiated
plans to restructure the operations of the combined company to eliminate certain duplicative activities, reduce costs and better align product and operating expenses with then current economic

conditions. These costs were accounted for as liabilities assumed as part of the business combination. The costs remaining as of March 27, 2011 and March 28, 2010 relate to office space
in Belgium that has been vacated but is under lease until March 2012 and were $81,000 and $209,000, respectively.

NOTE 8.    LONG-TERM INVESTMENT

Our long-term investment consists of our investment in Skypoint Telecom Fund II (US), L.P. (Skypoint Fund). Skypoint Fund is a
venture capital fund that invests primarily in private companies in the telecommunications and/or networking industries. We account for this non-marketable equity investment under the cost method. We periodically review and determine whether the
investment is other-than-temporarily impaired, in which case the investment is written down to its impaired value.

Our
investment in TechFarm Ventures L.P. (TechFarm Fund), to which we contributed our total commitment to the fund of $4.0 million in capital since we became a limited partner in May 2001, had a carrying amount of zero as of March 27,
2011 and March 28, 2010, reflecting the net of the capital contribution and the cumulative impairment charges.

As of
March 27, 2011 and March 28, 2010, our long-term investments balances, which are included in the other non-current assets line on the consolidated balance sheet, were as follows (in thousands):



|              |  |               |       |  |               |   |       |

We have made $4.7 million in capital contributions to Skypoint Fund since we became a limited partner in
July 2001. We contributed $186,000 and $41,000 to the fund during fiscal years of 2011 and 2010, respectively. As of March 27, 2011, we have a remaining potential capital commitment of approximately $0.3 million should the general partner
decide to request it up to June 30, 2011.

The carrying amount of $1.6 million reflects the net of the capital
contributions, cumulative impairment charges and capital distributions. We received capital distributions of $63,000 and $36,000, respectively, during fiscal year 2011 and fiscal year 2010.

NOTE 9.    GOODWILL AND INTANGIBLE ASSETS

Goodwill

Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired
in a business combination. We evaluate goodwill for impairment on an annual basis or whenever events and changes in circumstances suggest that the carrying amount may not be recoverable. We conduct our annual impairment analysis in the fourth
quarter of each fiscal year. Impairment of goodwill is tested at the reporting unit level by comparing the reporting units carrying amount, including goodwill, to the fair value of the reporting unit. The fair value of the reporting unit is
estimated using a combination of the income approach that uses discounted cash flows and the market approach that utilizes comparable companies data. If the carrying amount of the reporting unit exceeds its fair value, goodwill is considered
impaired and a second step is performed to measure the amount of impairment loss. Because we have one reporting unit, we utilize an entity-wide approach to assess goodwill for impairment.

In the fourth quarter of fiscal year 2011, we conducted our annual impairment review comparing the fair value of our one reporting unit
with its carrying value. As of the test date and as of year-end, and before consideration of a control premium, the fair value, which was estimated as our market capitalization, exceeded the carrying value of our net assets. As a result, no
impairment was recorded for fiscal year 2011.

In the fourth quarter of fiscal year 2010, we conducted our annual impairment
review comparing the fair value of our one reporting unit with the carrying value. Based on the results at the time of our analysis, the fair value, which was estimated as our market capitalization, exceeded the carrying value of our net assets. As
a result, no impairment was recorded for fiscal year 2010.

In the third quarter of fiscal year 2009, the rapid and severe
deterioration of worldwide economic conditions affected our industry and led customers to scale down their levels of production. As a result of these impairment indicators, we considered the potential impairment of goodwill. Indicators that required
us to perform an interim impairment review consisted of further weakening in new orders from our customers throughout the third quarter and into the fourth quarter of fiscal year 2009, as well as the uncertainty of the magnitude and duration of the
recession as evidenced by industry analysts expectations that demand for semiconductors would remain weak until economic conditions improve. In addition, we experienced a significant decline in our stock price that reduced our market capitalization
below our net asset carrying value for an extended period of time. We performed an interim goodwill impairment analysis and recorded a $46.2 million impairment loss that was included in the impairment of intangible assets and goodwill line in the
consolidated statements of operations.

Long-lived assets are amortized on a straight-line basis
over their respective estimated useful lives. We evaluate the remaining useful life of our long-lived assets that are being amortized each reporting period to determine whether events and circumstances warrant a revision to the remaining period of
amortization. If the estimate of an intangible assets remaining useful life is changed, the remaining carrying amount of the long-lived asset is amortized prospectively over the remaining useful life. Long-lived assets are evaluated for
impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. We compare the carrying value of long-lived assets to our projection of future undiscounted cash flows attributable to such
assets and, in the event that the carrying value exceeds the future undiscounted cash flows, we record an impairment charge equal to the excess of the carrying value over the assets fair value.

Although the assumptions used in projecting future revenues and gross margins are consistent with those used in our annual strategic planning process, intangible asset impairment charges might be
required in future periods if our assumptions are not achieved.

IPR&D assets are considered indefinite-lived intangible
assets and are not subject to amortization until their useful life is determined. IPR&D assets are evaluated for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired.

During the fourth quarter of fiscal year 2011, we decided to exit the data center virtualization market, and, in connection therewith, to
stop development of our 10GbE network interface cards. We determined that the current economic and market environment did not provide the potential to deliver acceptable returns on the required investments in these products. As a result, in the
fourth quarter of fiscal year 2011 we abandoned all related in-process research and development. In addition, we began to actively market for sale the related assets of our 10GbE technology, consisting primarily of underlying existing and core
technology intangible assets. Charges related to this decision in the fourth quarter of fiscal year 2011 included $7.5 million for the impairment of intangible assets, which is included within the impairment of intangible assets and goodwill line in
our consolidated statements of operations.

The intangible asset impairment charge of $7.5 million consists of $0.8 million to
the write-off abandoned IPR&D acquired in the Neterion acquisition and $6.7 million to write-down the carrying value of intangible assets that are held for sale to $0.2 million at March 27, 2011, which represents their estimated fair value
less costs to sell based on third-party bids received to date. In June 2011, we completed the asset sale process and received $0.2 million, net of selling costs.

As noted in the Goodwill discussion above, in the third quarter of fiscal year 2009, there were certain events that gave rise to impairment indicators and as a result we analyzed our long-lived assets for
impairment. The analysis determined that the carrying amount of the intangible assets exceeded the implied fair value under the test for impairment and the difference was allocated to the intangible assets of the impacted asset group on a pro-rata
basis using the relative carrying amounts of the assets. We recorded an impairment charge of approximately $13.5 million, which is included in the impairment of intangible assets and goodwill line in the consolidated statements of operations of
which $9.8 million related to existing technology, $1.4 million to patents/core technology, $1.3 million to distributor relationships, $0.9 million to customer relationships and $0.1 million to tradenames/trademarks.

The aggregate amortization expenses for our purchased intangible assets for fiscal years ended March 27, 2011, March 28,
2010 and March 29, 2009 were as follows (in thousands, except weighted average lives):

NOTE 10.    EARNINGS (LOSS) PER SHARE

Basic earnings (loss) per share excludes dilution and is computed by dividing net income (loss) by the weighted average number of common
shares outstanding for the periods. Diluted earnings per share (EPS) reflects the potential dilution that would occur if outstanding stock options or warrants to purchase common stock were exercised for common stock, using the treasury
stock method, and the common stock underlying outstanding restricted stock units (RSUs) was issued.

our loss per share for the three fiscal years of 2011, 2010 and 2009 was as follows (in thousands, except per share amounts):

Our application of the treasury stock method in determining the dilutive effect of stock options
and RSUs includes assumed cash proceeds from option exercises, the average unamortized stock-based compensation expense for the period, and the estimated deferred tax benefit or detriment associated with stock-based compensation expense.

NOTE 11.    COMMON STOCK REPURCHASES

From time to time, we acquire outstanding common stock in the open market to partially offset dilution from our equity award programs, to increase our return on our invested capital and to bring our cash
to a more appropriate level for our company.

On August 28, 2007, we announced the approval of a share repurchase plan
(2007 SRP) and authorized the repurchase of up to $100 million of our common stock.

During fiscal years 2011 and
2010, we did not repurchase any shares of our common stock.

As of March 27, 2011, the remaining authorized amount for
share repurchases under the 2007 SRP was $11.8 million. The 2007 SRP does not have a termination date. We may continue to utilize our share repurchase plan, which would reduce our cash, cash equivalents and/or short-term marketable securities
available to fund future operations and to meet other liquidity requirements.

NOTE 12.    EMPLOYEE BENEFIT PLANS

Exar Savings Plan

The Exar Savings Plan, as amended and restated, covers our eligible U.S. employees. The Exar Savings Plan provides for voluntary salary reduction contributions in accordance with Section 401(k) of
the Internal Revenue Code as well as matching contributions from the company based on the achievement of specified operating results.

Our matching contributions to the plan for the three fiscal years of 2011, 2010 and 2009 were as follows (in thousands):

NOTE 13.    STOCK-BASED COMPENSATION

Employee Stock Participation Plan (ESPP)

Our ESPP
permits employees to purchase common stock through payroll deductions at a purchase price that is equal to 95% of our common stock price on the last trading day of each three-calendar-month offering period. Our ESPP is non-compensatory.

Equity Incentive Plans

We currently have three equity incentive plans including the Exar Corporation 2006 Equity Incentive Plan (the 2006
Plan) and two other equity plans assumed upon our August 2007 acquisition of Sipex: the Sipex Corporation Amended and Restated 2002 Non-Statutory Stock Option Plan and the Sipex Corporation 2006 Equity Incentive Plan (collectively, the
Sipex Plans). The Sipex Corporation 2000 Non-Qualified Stock Option Plan expired October 31, 2010.

The 2006
Plan authorizes the issuance of stock options, stock appreciation rights, restricted stock, stock bonuses and other forms of awards granted or denominated in common stock or units of common stock, as well as cash bonus awards. RSUs granted under the
2006 Plan are counted against authorized shares available for future issuance on a basis of two shares for every RSU issued. The 2006 Plan allows for performance-based

Valuation Assumptions

The assumptions used in calculating the fair value of stock-based compensation represent our estimates, but these estimates involve inherent uncertainties and the application of management judgments which
include the expected term of the share-based awards, stock price volatility and forfeiture rates. As a result, if factors change and we use different assumptions, our stock-based compensation expense could be materially different in the future.

Valuation Methodwe compute the fair value of stock options utilizing the Black-Scholes option pricing model.

Expected Termwe estimate the expected life of options granted based on historical exercise and post-vest
cancellation patterns, which we believe are representative of future behavior.

Volatilityour expected volatility
is based on historical data of the market closing price for our common stock as reported by The NASDAQ Global Market under the symbol EXAR and the expected term of our stock options.

Risk-Free Interest Ratethe risk-free interest rate assumption is based on the observed interest rate of the U.S. Treasury
appropriate for the expected term of the option to be valued.

Dividend Yieldwe do not currently pay dividends
and have no plans to do so in the future. Therefore, we have assumed a dividend yield of zero.

RSUs

We issue RSUs to employees and non-employee directors. RSUs generally vest on the first or third anniversary date from the grant date,
although the RSUs issued in exchange for options tendered in our option exchange program in the third quarter of fiscal year 2009 vested in two equal annual installments. Prior to vesting, RSUs do not have dividend equivalent rights, do not have
voting rights and the shares underlying the RSUs are not considered issued and outstanding. Shares are issued on the date the RSUs vest.

A summary of RSU transactions during the periods indicated for all stock option plans is as follows:

In July 2009, we granted performance-based RSUs covering 99,000 shares to certain
executives, issuable upon meeting certain performance targets in fiscal year 2010 and vesting annually over a three year period beginning July 1, 2010. The annual vesting requires continued service through each annual vesting date. During
fiscal year 2011 and fiscal year 2010, $216,000 and $368,000, respectively, of compensation expense was recorded to reflect the achievement of these performance targets.

In April 2010, we granted performance-based RSUs covering 56,000 shares to our CEO, issuable upon meeting certain performance targets in our fiscal year 2011 and vesting annually over a three year period
beginning May 3, 2010. The annual vesting requires continued service through each annual vesting date. During fiscal year 2011, $239,000 of compensation expense was recorded for these awards.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(CONTINUED)

FISCAL YEARS ENDED MARCH 27, 2011, MARCH 28, 2010, AND MARCH 29, 2009



Option Exchange Program

On October 23, 2008, we commenced a tender offer (the Offer) and filed a Schedule TO with the SEC pursuant to which
holders of options with exercise prices equal to or greater than $11.00 per share and an expiration date after March 31, 2009 could tender their options in exchange for RSUs awards. The exchange ratio of shares subject to such eligible options
to shares subject to new awards issued was 4-to-1, 5-to-1 or 6-to-1, depending on the exercise price of the option being exchanged. New awards received in exchange for eligible options are subject to a two-year vesting schedule with 50% vesting at
each anniversary of the grant date.

Pursuant to the Offer, 242 eligible participants tendered, and we accepted for exchange,
options to purchase an aggregate of 1,650,231 shares of our common stock, representing approximately 94% of the 1,755,691 shares subject to options that were eligible to be exchanged in the Offer as of the commencement of the Offer on
October 23, 2008. On November 24, 2008, upon the terms and subject to the conditions set forth in the Offer to Exchange Certain Outstanding Options for Restricted Stock Units, filed as an exhibit to the Schedule TO, we issued RSU awards
covering an aggregate of 344,020 shares of our common stock in exchange for the options surrendered pursuant to the Offer.

The new awards were granted with a price of $6.51 per share, the closing price of our common stock on November 24, 2008 as reported
on The NASDAQ Global Select Market. The fair value of the options exchanged was measured as the total of the unrecognized compensation cost of the original options tendered and the incremental compensation cost of the RSUs awarded on
November 24, 2008, the date of exchange. The incremental compensation cost of $1.2 million, was measured as the excess of the fair value of the RSUs over the fair value of the options immediately before cancellation based on the share price and
other pertinent factors at that date. The amount was amortized over the two years service period. During fiscal years 2011, 2010 and 2009, we recorded approximately $327,000, $530,000 and $208,000, respectively, of such incremental stock-based
compensation expense.

NOTE 14.    WARRANTS

In connection with the Sipex acquisition, we assumed warrants with a fair value of $1.5 million on the date of acquisition, which enable
the holders, to purchase a total of approximately 280,000 shares of our common stock. The warrants were exercisable at any time for shares of our common stock at an initial exercise price of $9.63 per share, subject to adjustment upon certain
events. The warrants expired unexercised on May 18, 2011.

NOTE 15.    LEASE FINANCING OBLIGATION

In connection with the Sipex acquisition, we assumed a lease financing obligation related to the Hillview facility located
in Milpitas, California (the Hillview Facility). The lease term expired March 31, 2011 and had average lease payments of approximately $1.4 million per year.

The fair value of the Hillview Facility was estimated at $13.4 million at the time of the acquisition and was included in the property, plant and equipment, net line on the consolidated balance sheet. In
accordance with purchase accounting, we have accounted for this sale and leaseback transaction as a financing transaction which was included in the long-term lease financing obligations line on our consolidated balance sheet. The effective interest
rate is 8.2%.

|(1) | At the end of the lease term, March 31, 2011, the estimated final lease obligation was approximately $12.2 million, which we settled in a noncash transaction by
returning the Hillview Facility to the lessor. As a result, during the first quarter of fiscal year 2012, the property, plant and equipment balance and the long-term lease financing obligations balance on our consolidated balance sheet and will both
decline by approximately $12.2 million.

Interest expense for the Hillview Facility lease financing obligation
and design tools for the periods indicated below was as follows (in thousands):

In the course of our
business, we enter into arrangements accounted for as operating leases. Our current arrangements relate to engineering design software licenses and office space. As of March 27, 2011, our future obligations under these arrangements were $5.7
million and $1.5 million, respectively.

In fiscal year 2011, the lessor for the Hillview Facility made a remediation claim
for damages related to our lease. Based on such claim, we submitted a proposal to the lessor to settle the claim and recorded an accrual of $0.4 million in fiscal year 2011.

NOTE 16.    COMMITMENTS AND CONTINGENCIES

In
1986, Micro Power Systems Inc. (MPSI), a subsidiary that we acquired in June 1994, identified low-level groundwater contamination at its principal manufacturing site. The area and extent of the contamination appear to have been defined.
MPSI previously reached an agreement with a prior tenant to share in the cost of ongoing site investigations and the operation of remedial systems to remove subsurface chemicals. The frequency and number of wells monitored at the site was reduced
with prior regulatory approval for a plume stability analysis as an initial step towards site closure. No significant rebound concentrations have been observed. The groundwater treatment system remains shut down. In July 2008, we evaluated the
effectiveness of the plume stability and decided to initiate an alternative treatment program to pursue a no further action order for the site. The program was approved by the state and implementation started in October 2009. As of March 27,
2011 and March 28, 2010, the outstanding liabilities for remediation options and future monitoring were $113,000 and $137,000, respectively.

Generally, we warrant all custom products and application specific products, including cards and boards, against defects in materials and workmanship for a period of 12 months and occasionally we may
provide an extended warranty of up to three years from the delivery date. We warrant all of our standard products against defects in materials and workmanship for a period of 90 days from the date of delivery. Reserve requirements are recorded in
the period of sale and are based on an assessment of the products sold with warranty and historical warranty costs incurred. Our liability is generally limited to replacing, repairing or issuing credit, at our option, for the product if it has been
paid for. The warranty does not cover damage which results from accident, misuse, abuse, improper line voltage, fire, flood, lightning or other damage resulting from modifications, repairs or alterations performed other than by us, or resulting from
failure to comply with our written operating and maintenance instructions. Warranty expense has historically been immaterial for our products. The warranty liabilities related to our products as of March 27, 2011 and March 28, 2010 were
immaterial.

In the ordinary course of business, we may provide for indemnification of varying scope
and terms to customers, vendors, lessors, business partners, purchasers of assets or subsidiaries, and other parties with respect to certain matters, including, but not limited to, losses arising out of our breach of agreements or representations
and warranties made by us, services to be provided by us, intellectual property infringement claims made by third parties or, with respect to the sale of assets or a subsidiary, matters related to our conduct of the business and tax matters prior to
the sale. In addition, we have entered into indemnification agreements with our directors and certain of our executive officers that will require us, among other things, to indemnify them against certain liabilities that may arise by reason of their
status or service as directors or executive officers. We maintain director and officer liability insurance, which may cover certain liabilities arising from our obligation to indemnify our directors and officers, and former directors and officers of
acquired companies, in certain circumstances. It is not possible to determine the aggregate maximum potential loss under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and
circumstances involved in each particular agreement. Such indemnification agreements might not be subject to maximum loss clauses. Historically, we have not incurred material costs as a result of obligations under these agreements and we have not
accrued any liabilities related to such indemnification obligations in our consolidated financial statements.

NOTE 17.    LEGAL PROCEEDINGS

From time to time, we are involved in various claims, legal actions and complaints arising in the normal course of business. We are not a named party to any currently ongoing lawsuit or formal proceeding
that, in the opinion of our management, is likely to have a material adverse effect on our financial position, results of operations or cash flows.

FISCAL YEARS ENDED MARCH 27, 2011, MARCH 28, 2010, AND MARCH 29, 2009



As of March 27, 2011, our federal and state tax credit carryforwards were $9.0
million and $11.0 million, respectively. Federal credits will begin to expire in fiscal year 2016. Canadian credits will begin to expire in fiscal year 2015.

Utilization of these federal and state net operating loss and tax credit carryforwards may be subject to a substantial annual limitation due to the ownership change limitations provided by the Internal
Revenue Code of 1986, as amended, and similar state provisions.

We have evaluated our deferred tax assets and concluded that
a valuation allowance is required for that portion of the total deferred tax assets that are not considered more likely than not to be realized in future periods. To the extent that the deferred tax assets with a valuation allowance become
realizable in future periods, we will have the ability, subject to carryforward limitations, to benefit from these amounts. Approximately $13.0 million of these deferred tax assets pertain to certain net operating loss and credit carryforwards that
resulted from the exercise of employee stock options. When recognized, the tax benefit of these carryforwards is accounted for as a credit to additional paid-in capital rather than a reduction of the income tax provision.

Uncertain Income Tax Benefits

A reconciliation of the beginning and ending amount of the unrecognized tax benefits during the tax year ended March 27, 2011 is as follows (in thousands):

|Unrecognized tax benefits as of March 28, 2010       |  |        | 15,863 |  
|Gross increase related to prior year tax positions   |  |        | 179    |

|Lapses in statute of limitation                      |  |        | (185   | )

Of the total unrecognized gross tax benefit of $16.7 million, $3.7 million is presented within income taxes
payable, non-current, and $13.0 million is presented as a reduction to deferred tax assets. We do not anticipate a significant increase or decrease to our unrecognized tax benefits within the next twelve months.

Estimated interest and penalties related to the underpayment of income taxes are classified as a component of the provision for income
taxes in the consolidated statement of operations. Accrued interest and penalties were $0.3 million and $0.4 million as of March 27, 2011 and March 28, 2010, respectively.

Our only major tax jurisdictions are the United States federal and various states. The fiscal years 2001 through 2010 remain open and
subject to examinations by the appropriate governmental agencies in the United States and certain of our state jurisdictions.

NOTE 21.    SUPPLEMENTARY QUARTERLY FINANCIAL DATA (UNAUDITED)

The following table contains selected unaudited quarterly financial data for fiscal years 2011 and 2010. In the opinion of management,
this unaudited information has been prepared on the same basis as the audited information and includes all adjustments, consisting only of normal and recurring adjustments necessary to state fairly the information set forth therein. Results for a
given quarter are not necessarily indicative of results for any subsequent quarter (in thousands, except per share data. Net loss per share for the four quarters of each fiscal year may not sum to the total for the fiscal year, because of the
different number of shares outstanding during each period).

Disclosure
Controls and Procedures

Evaluation of Disclosure Controls and Procedures (Disclosure Controls)

Disclosure Controls, as defined in Rule 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended (the Exchange
Act), are controls and procedures designed to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods as specified in the
SECs rules and forms. In addition, Disclosure Controls are designed to ensure the accumulation and communication of information required to be disclosed in reports filed or submitted under the Exchange Act to our management, including the
Chief Executive Officer (our principal executive officer) (the CEO) and Chief Financial Officer (our principal financial officer) (the CFO), to allow timely decisions regarding required disclosure.

We evaluated the effectiveness of the design and operation of our Disclosure Controls, as defined by the rules and regulations of the SEC
(the Evaluation), as of the end of the period covered by this Annual Report. This Evaluation was performed under the supervision and with the participation of management, including our CEO, as principal executive officer, and CFO, as
principal financial officer.

Attached as Exhibits 31.1 and 31.2 of this Annual Report are the certifications of the CEO and
the CFO, respectively, pursuant to Section 302 of the Sarbanes-Oxley Act of 2002 (the Certifications). This section of the Annual Report provides information concerning the Evaluation referred to in the Certifications and should be
read in conjunction with the Certifications.

Based on the Evaluation, our CEO and CFO have concluded that our Disclosure
Controls are effective as of the end of fiscal year 2011.

Inherent Limitations on the Effectiveness of Disclosure Controls

Our management, including the CEO and CFO, does not expect that our Disclosure Controls will prevent all errors and all fraud. Disclosure
Controls, no matter how well conceived, managed, utilized and monitored, can provide only reasonable assurance that the objectives of such controls are met. Therefore, because of the inherent limitation of Disclosure Controls, no evaluation of such
controls can provide absolute assurance that all control issues and instances of fraud, if any, within us have been detected.

Managements Annual Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting. Management conducted an
assessment of our internal control over financial reporting as of March 27, 2011 based on the framework established by the Committee of Sponsoring Organizations of the Treadway Commission inInternal ControlIntegrated Framework .
Based on this assessment, management concluded that, as of March 27, 2011, our internal control over financial reporting was effective.

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. However, these
inherent limitations are known features of the financial reporting process. Therefore it is possible to design into the process safeguards to reduce, though not eliminate, this risk.

The effectiveness of our internal control over financial reporting as of March 27, 2011 has been audited by PricewaterhouseCoopers
LLP, an independent registered public accounting firm, as stated in their report included in this Annual Report.

Changes in Internal
Control over Financial Reporting

There was no change in our internal control over financial reporting that occurred during
the fourth quarter of fiscal year 2011 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
