On June 17, 2009, we completed the acquisition of Galazar. Galazar, based in Ottawa,
Ontario, Canada, was a fabless semiconductor company and software supplier focused on carrier grade transport over telecom networks. Galazars product portfolio addresses 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
Hifn, a fabless semiconductor company that was founded in 1996, spun off from Stac, Inc. in 1999 and traded on the NASDAQ under the symbol HIFN since 1999. The acquisition of Hifn expands and complements 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 adds 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.

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, Datacom & Storage Products, Communication Products, Interface Products and
Power Management Products, that define products based on market opportunities and trends. We believe such product line orientation allows for the concentration of market-specific technical expertise which enables us to connect product solutions to
the largest users in a given market segment.

We believe our core competencies include:

Leading Analog and Mixed-Signal Design ExpertiseWe have over 35 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, that we leverage across our broad range of products from
programmable power management chips to virtualized network interface products that possess a high 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 technology and
system-level expertise allows 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 compute 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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 acquisition activity in the last year. With the addition of Hifn, Galazar and Neterion, we extended our portfolio of products to offer new
silicon products, card solutions 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.
These solutions 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 that are based on standard Complementary Metal Oxide Semiconductor (CMOS) process
technologies. The goal of our product development efforts is to use our intellectual property to create and integrate differentiated solutions that provide speed advantages and power reductions.

Conscious Preservation InitiativeEnvironmental concerns are having 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. To that end, we have taken the initiative to offer a portfolio of products
that is truly green by transitioning our manufacturing processes to offer semiconductor devices that exceed the Restriction of Hazardous Substances Directive (RoHS) requirements and are halogen-free.

MARKETS AND PRODUCTS

Datacom and
Storage

Todays information technology infrastructure is going through significant changes, and a few of the key
trends driving such changes in data center architectures and the underlying technologies that support them present an opportunity for us to influence our product decisions. We believe the most significant trend is the rapid growth of raw storage
capacity requirements that is driven by the increase in digital media content and the expanded base of users. The tremendous growth in content requires efficient ways to store and retrieve data quickly. Another significant trend is Cloud
Computing and the need to re-architect existing data centers to achieve higher levels of hardware utilization. Many existing data centers worldwide are struggling to keep up with demand, are inefficient in the way they virtualize applications
and consume too much power. The upgrade process for such data centers will drive demand for servers, storage systems, software and a range of technologies to facilitate efficiencies. Further, the threat of a breakdown in secure transactions has
become an enormous concern for IT departments around the world. Even a minor security breach in the IT infrastructure can cost tens of millions of dollars. The need to pass data securely through advanced encryption algorithms creates an opportunity
to provide semiconductor solutions that protect sensitive data and exceed the government requirements for secure transactions.

To address such changes, our Datacom & Storage product portfolio provides a range of solutions for OEMs and IT organizations to
efficiently optimize, secure, and transport data in next generation data centers. Our value proposition is driven by underlying hardware offload technology. The concept of offload is to use very efficient, dedicated hardware to provide functionality
that would otherwise need to be done with power-hungry x86 application processors. General-purpose application processors are very flexible, but inefficient. The advantages of hardware offload are:



| |  |  | High performance and scalabilitythey are dedicated to a specific task and architected for parallelism
| | - |  | ------------------------------------------------------------------------------------------------------



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



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

Our Datacom & Storage solutions provide hardware offload capabilities that are an ideal complement to the capabilities of costly
application processors. Given the cost of server application processors, using them 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 one percent 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 target optimization of the IT infrastructure. With the move to highly virtualized data centers, the
strain on the network is growing, requiring migration to 10 Gigabit Ethernet solutions that provide high performance connectivity specifically architected for a virtualized environment. To help manage growing requirements placed on network bandwidth
and storage infrastructure, the capability to minimize data footprint with compression, and eliminate redundancy with deduplication is becoming increasingly valued. Finally, a virtualized environment moves the burden of security from the edge of the
data

software. The Neterion products are supported by proven, enterprise-class software with support for the broadest range of operating systems and hypervisors in the industry.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Data Security and CompressionOur line of ASIC and Express 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 allows 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 is a comprehensive solution for in-line data deduplication for primary 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.

global service provider networks. Conforming to international standards for the copper, fiber optic and wireless protocols, our broad portfolio of PDH, SONET, SDH and OTN products enable the delivery of highly reliable, value added communication
services.

T/E Carrier

Service providers have a large investment in their existing copper infrastructure. This infrastructure remains a cost
effective means of providing high value leased line and data services for enterprises, mobile backhaul and network interconnection. Exar offers a comprehensive portfolio of T1 and E1 devices for twisted pair copper and DS3 and E3 devices for coaxial
copper connections. Our broad range of T1/E1 devices includes short-haul and long-haul 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), 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.

Optical Transport Networks (OTN)

With the substantial growth of internet, wireless and broadband traffic, the demands on service providers for faster, high bandwidth, more
reliable networks for ubiquitous services resulted in the development of the 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 universally 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 Protocol (IP) 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. Exars extensive portfolio of Ethernet over PDH (EoPDH), Ethernet over SONET/SDH (EoS) and Ethernet over OTN enable the efficient mapping of
Ethernet packets into flexible bandwidth transport networks.

Interface

We provide the broadest line of industry-proven Universal Asynchronous Receiver/Transmitter (UART) solutions as well as
synergistic serial transceiver devices into pervasive applications in industrial, telecommunications and consumer markets. Typical applications served by our serial communications products include Point-of-Sale (POS), process control,
factory automation as well as servers, embedded systems, routers, network management equipment, remote access servers, wireless base-stations and repeaters. Additionally, our single and multi-channel UARTs are used in portable consumer applications
such as multi-media, Global Positioning System (GPS), Personal Digital Assistant (PDA) and smart phone devices.

Our UART product portfolio ranges from cost-effective industry-standard devices to high-performance multi-channel
UARTs with a broad range of First In, First Out (FIFO) depths and industry leading performance and features that support popular interfaces such as 8-bit Industry Standard Architecture (ISA), 8-bit VLIO, 2-wire
Inter-Integrate Circuit (I2C), 4-wire Serial
Peripheral Interface (SPI), Peripheral Component Interconnect (PCI), Peripheral Component Interconnect Express (PCIe) and Universal Serial Bus (USB). In addition, we were first to market with a
wireless UART solution that includes a high-performance UART, controller and Radio Frequency (RF) functionality along with our proprietary firmware that enables the application to send and receive data wirelessly over a secure
proprietary protocol.

Our serial transceiver solutions consist of Recommended Standard (RS)-232, RS-485, RS-422
and multiprotocol devices that ensure reliable connectivity between computing devices. Our RS-232, RS-485 and RS-422 transceivers comply with international standards in delivering multi-channel digital signals between two systems. Our proprietary
multiprotocol transceivers enable network equipment to communicate with a large population of peripherals that use a diverse set of serial protocol standards without the added burden of multiple add-on boards and cables.

Power Management

The power management market has changed considerably over time. The practice of deferring power considerations to the final stages of the
system design has given rise to increased difficulties in space, available energy and heat dissipation. Power management has now moved from the final design stage to one of the primary considerations when defining a system. As a result, power
solutions today are challenged to solve a variety of these problems.

While the latest generation of
consumer, communication and industrial products are delivering lower-power, feature-rich devices, system architects for these new products are being inundated with several new and complex challenges. As embedded intelligence and features increase,
the requirements for multiple voltages and currents, temperature stability and the associated power sequencing and monitoring become daunting tasks for the system designer. Additionally, time-to-market considerations are placing significant schedule
demands on product manufacturers forcing the use of concurrent engineering methodologies. For the developers of end products, this means that their system architecture, software and hardware design efforts are happening at the same time as the
required next generation integrated circuits are completing their development cycle. This perfect storm of simultaneous engineering has become the norm for product manufacturers and has created a demand for more flexibility in the
system design process. PowerXR, our new line of
programmable power management products provides system designers with the ability to reconfigure the power management sub-system throughout the development cycle and even in the field if required. Simply by using
PowerXRtechnology, product development cycles are being
reduced from many months to several weeks. This change in product development methodology is happening right now and we are at the forefront of the industry in providing the enabling high performance and cost effective programmable power solutions
that make it 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 an internal engineering team. PowerXRtechnology
combines digital control and monitoring with our high performance analog circuitry allowing the system architect to design products that reduce wasted energy by orders of magnitude and are reconfigurable on the fly. 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 silicon area required by other non-configurable technologies.

All 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 fabs 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 Exar competitive with the
worlds best manufacturers of analog power management products. Our goal is to be the clear technology leader in the fast growing market for programmable power management products.

While we believe our programmable power products represent a fundamental advance 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 those found in PowerXRproducts. Our
portfolio of power products is focused on a range of solutions that offer power management, voltage conversion and Light-Emitting Diode (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 one goal in mind: make power system design easy. In doing so, we seek to lower the costs 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 interfaces in 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 optimized solutions that are designed to be technically compelling and cost effective, resulting in distinctive products like Tethys, 10G Sonet Multiplexer (Mux)/DeMux,
Flowthough® Security Processors, Bitwackr data deduplication solutions and
PowerXR. These solutions and others provide platform
engagements that involve software and hardware integration at the system level resulting in a deeper 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.

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, 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 in sales and marketing.

Broaden Sales Coverage with Channel PartnersWe have strong relationships with our distributors 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 support directly. 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 Americas, we are
represented by 17 independent sales representative groups and two independent, non-exclusive primary distributors, as well as our own direct sales organization. In addition, we have two independent, non-exclusive

Networks, Pace, Panasonic Corporation, Parrot, Samsung Electronics, 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 Malaysia, China, Indonesia 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 soon will be automotive specification TL16949 compliant.

For all acquired Hifn, Galazar and Neterion products currently in production, we will continue to use the turnkey manufacturing model,
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. While we continually upgrade our internal technology to develop innovative
products, as a fabless company, we also work with foundries that provide our wafers. 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 with
Galazar and Neterion invested $48.5 million, $31.8 million and $30.7 million on research and development in fiscal years 2010, 2009 and 2008, respectively. For the 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;
| | - |  | ------------------------------



| |  |  | price;
| | - |  | ------



| |  |  | rapid technological change;
| | - |  | ---------------------------



| |  |  | number of design wins released to production;
| | - |  | ---------------------------------------------



| |  |  | lowering total system cost;
| | - |  | ---------------------------



| |  |  | 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;
| | - |  | -------------------------



| |  |  | stronger financial position and liquidity;

| |  |  | access to larger customer bases;
| | - |  | --------------------------------



| |  |  | broader product offerings;
| | - |  | --------------------------



| |  |  | deeper engagement; and
| | - |  | ----------------------



| |  |  | significantly greater sales and marketing, and other resources.
| | - |  | ---------------------------------------------------------------

Because IC markets are highly fragmented, we generally encounter different competitors in our various target markets.
Competitors with respect to our communications products include Applied Micro Circuits Corporation, Integrated Device Technology, Inc., Maxim Integrated Products, Inc., Mindspeed Technologies, Inc., PMC-Sierra, Inc., TranSwitch Corporation and
Vitesse Semiconductor Corporation. Competitors in the datacom and storage market include Broadcom, Cavium Networks and Netlogic Microsystems. Competitors in the serial interface market include NXP B.V., Texas Instruments Incorporated, Analog
Devices, Inc., Intersil Corporation, Linear Technology Corporation and Maxim Integrated Products, Inc. Our primary competitors with respect to our power products include Advanced Analogic Technologies Incorporated, Analog Devices, Inc., Intersil
Corporation, Linear Technology Corporation, Maxim Integrated Products, Inc., Micrel Incorporated, National Semiconductor Corporation, On 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. We have 200 patents issued and 59 patent applications pending in the United States. We have 37 patents issued and 167 patent applications pending in various foreign countries. Our existing
patents will expire between 2010 and 2028, 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



13



---

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. SeePart 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.

Employees

As of
March 28, 2010, we employed 572 full-time employees, with 316 in research and development, 95 in operations, 88 in marketing and sales and 73 in administration. Of the 572 employees, 196 are located in our international offices. See Part I,
Item 1ARisk Factors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. None of our employees are represented by a collective
bargaining agreement, and we have never experienced a work stoppage due to labor issues.

|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, 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, currently showing signs of recovery,
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 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;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 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, liquid, and 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 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
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



17



---

| | 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 foundry, 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 financial results may fluctuate significantly because of a number of
factors, many of which are beyond our control.

Our financial results may fluctuate significantly as a result of a
number of factors, many of which are difficult or impossible to control or predict, which include:



| |  |  | the depth and duration of the current economic downturn;
| | - |  | --------------------------------------------------------



| |  |  | the cyclical nature of the semiconductor industry;
| | - |  | --------------------------------------------------



| |  |  | difficulty in predicting revenues and ordering the correct mix of products from suppliers due to limited visibility provided by customers and channel
partners;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | fluctuations of our revenue and gross profits due to the mix of product sales as our margins vary by product;
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | the impact of our revenue recognition policies on reported results; and
| | - |  | -----------------------------------------------------------------------



| |  |  | the reduction, rescheduling, cancellation or timing of orders by our customers, distributors and channel partners due to, among others, the following
factors:

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



| |  |  | inability of our subcontractors to provide quality products, in adequate quantities and in a timely manner;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | dependency on a single product with a single customer and/or distributor;
| | - |  | -------------------------------------------------------------------------



| |  |  | volatility of demand for equipment sold by our large customers, which in turn, introduces demand volatility for our products;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | disruption in customer demand as customers change or modify their complex subcontract manufacturing supply chain;
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | disruption in customer demand due to technical or quality issues with our devices or components in their system;
| | - |  | ----------------------------------------------------------------------------------------------------------------



| |  |  | the inability of our customers to obtain components from their other suppliers;
| | - |  | -------------------------------------------------------------------------------



| |  |  | disruption in sales or distribution channels;
| | - |  | ---------------------------------------------



| |  |  | our ability to maintain and expand distributor relationships;
| | - |  | -------------------------------------------------------------



| |  |  | changes in sales and implementation cycles for our products;
| | - |  | ------------------------------------------------------------



18

| |  |  | the ability of our suppliers and customers to remain solvent, obtain financing or fund capital expenditures as a result of the current global economic
slowdown;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | risks associated with entering new markets;
| | - |  | -------------------------------------------



| |  |  | the announcement or introduction of products by our existing competitors or new competitors;
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | loss of market share by our customers;
| | - |  | --------------------------------------



| |  |  | competitive pressures on selling prices or product availability;
| | - |  | ----------------------------------------------------------------



| |  |  | pressures on selling prices overseas due to foreign currency exchange fluctuations;
| | - |  | -----------------------------------------------------------------------------------

revenue and margins;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | delays in product design releases;
| | - |  | ----------------------------------



| |  |  | market and/or customer acceptance of our products;
| | - |  | --------------------------------------------------



| |  |  | consolidation among our competitors, our customers and/or our customers customers;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | changes in our customers end user concentration or requirements;
| | - |  | -----------------------------------------------------------------



| |  |  | loss of one or more major customers;
| | - |  | ------------------------------------



| |  |  | significant changes in ordering pattern by major customers;
| | - |  | -----------------------------------------------------------



| |  |  | our or our channel partners ability to maintain and manage appropriate inventory levels;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | the availability and cost of materials and services, including foundry, assembly and test capacity, needed by us from our foundries and other
manufacturing suppliers;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | disruptions in our or our customers supply chain due to natural disasters, fire, outbreak of communicable diseases, labor disputes, civil unrest
or other reasons;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | delays in successful transfer of manufacturing processes to our subcontractors;
| | - |  | -------------------------------------------------------------------------------



| |  |  | fluctuations in the manufacturing output, yields, and capacity of our suppliers;
| | - |  | --------------------------------------------------------------------------------



| |  |  | fluctuation in suppliers capacity due to reorganization, relocation or shift in business focus, financial constraints, or other reasons;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | problems, costs, or delays that we may face in shifting our products to smaller geometry process technologies and in achieving higher levels of design
and device integration;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability to successfully introduce and transfer into production new products and/or integrate new technologies;
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | increased manufacturing costs;
| | - |  | ------------------------------



| |  |  | higher mask tooling costs associated with advanced technologies; and
| | - |  | --------------------------------------------------------------------



| |  |  | the amount and timing of our investment in research and development;
| | - |  | --------------------------------------------------------------------

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



| |  |  | the timing and amount of employer payroll tax to be paid on our employees gains on stock options exercised;
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | inability to generate profits to utilize net operating losses;
| | - |  | --------------------------------------------------------------



| |  |  | increased costs and time associated with compliance with new accounting rules or new regulatory requirements;
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | changes in accounting or other regulatory rules, such as the requirement to record assets and liabilities at fair value;
| | - |  | ------------------------------------------------------------------------------------------------------------------------



19



---

| |  |  | write-off of some or all of our goodwill and other intangible assets;
| | - |  | ---------------------------------------------------------------------



| |  |  | fluctuations in interest rates and/or market values of our marketable securities;
| | - |  | ---------------------------------------------------------------------------------



| |  |  | litigation costs associated with the defense of suits brought or complaints made against us; and
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | change in or continuation of certain tax provisions.
| | - |  | ----------------------------------------------------

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.

If we fail to
develop, introduce or enhance products that meet evolving market needs or which are necessitated by technological advances, or we are unable to grow revenues, then our business, financial condition and results of operations could be materially and
adversely impacted.

The markets for our products are characterized by a number of factors, some of which are listed
below:



| |  |  | changing or disruptive technologies;
| | - |  | ------------------------------------



| |  |  | evolving and competing industry standards;
| | - |  | ------------------------------------------



| |  |  | changing customer requirements;
| | - |  | -------------------------------



| |  |  | increasing price pressure;
| | - |  | --------------------------



| |  |  | increasing product development costs;
| | - |  | -------------------------------------



| |  |  | long design-to-production cycles;
| | - |  | ---------------------------------



| |  |  | competitive solutions;
| | - |  | ----------------------



| |  |  | fluctuations in capital equipment spending levels and/or deployment;
| | - |  | --------------------------------------------------------------------



| |  |  | rapid adjustments in customer demand and inventory;
| | - |  | ---------------------------------------------------



| |  |  | increasing functional integration;
| | - |  | ----------------------------------



| |  |  | moderate to slow growth;
| | - |  | ------------------------



| |  |  | frequent product introductions and enhancements;
| | - |  | ------------------------------------------------



| |  |  | changing competitive landscape (consolidation, financial viability); and
| | - |  | ------------------------------------------------------------------------



| |  |  | finite market windows for product introductions.
| | - |  | ------------------------------------------------

Our growth depends in part on our successful continued development and 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, the trend towards increasing 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.



20



---

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 expenses 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 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;
| | - |  | ---------------------------------------------------------



| |  |  | 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;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



21



---

| |  |  | 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;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | reduction in liquidity and interest income on lower cash balances;
| | - |  | ------------------------------------------------------------------



| |  |  | recording of goodwill and intangible assets that will be subject to periodic impairment testing and potential impairment charges against our future
earnings;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | incurring amortization expenses related to certain intangible assets;
| | - |  | ---------------------------------------------------------------------



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



| |  |  | incurring large and immediate write-offs; and
| | - |  | ---------------------------------------------



| |  |  | being subject to litigation.
| | - |  | ----------------------------

Additional risks involved with strategic equity investments include:



| |  |  | the possibility of litigation resulting from these types of investments;
| | - |  | ------------------------------------------------------------------------



| |  |  | the possibility that we may not receive a financial return on our investments or incur losses from these investments;
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | a changed or poorly executed strategic plan; and
| | - |  | ------------------------------------------------



| |  |  | the opportunity cost associated with committing capital in such investments.
| | - |  | ----------------------------------------------------------------------------

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 current 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, 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.

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, 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.

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 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 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 harm 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 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 recruitment 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 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 in modern banking, computer and other control systems, making the successful identification and employment of qualified personnel
particularly important, and hiring



24



---

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 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.

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 indemnification 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 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.

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 GAAP, the excess purchase price, if any, over 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. 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 must be
tested for impairment annually or more frequently if events



25



---

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 with its carrying amount. If the carrying
amount of the IPR&D 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 will be its new accounting basis. If the
fair value of the IPR&D 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. 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 materially and adversely impact on our business, financial
condition and results of operations.

Our business may be 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 such as 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 factors 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.

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 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 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



26



---

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.

Affiliates of Future, Alonim Investments Inc. and two of its affiliates (collectively Alonim), own
approximately 17% of our common stock, and as such, Alonim is our largest stockholder. This ownership position will allow Future to significantly influence matters requiring stockholder approval. Futures ownership may increase as a percentage
of our outstanding shares if we repurchase our common stock. In addition, an executive officer of Future is on our board of directors, which could lead to actual or perceived influence from Future.

An affiliate of Future, our largest distributor, owns a significant percentage of our outstanding shares and Pierre Guilbault, the chief
financial officer of Future, is a member of our board of directors. Due to its affiliates ownership of a significant percentage of our common stock, Future 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. The significant ownership percentage of Future could have the effect of delaying or preventing a change of
control or otherwise discouraging a potential acquirer from obtaining control of us. Conversely, by virtue of Futures percentage ownership of our stock, Future could facilitate a takeover transaction that our board of directors did not
approve.

This relationship 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.

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 subcontractors capacity to manufacture 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 Polar Semiconductor (MN, USA) and 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.

We do not have long-term wafer supply agreements with Globalfoundries that would guarantee wafer quantities, prices, and delivery or lead
times, but we do provide minimum purchase commitments to Silan and Episil in accordance with our supply agreements. Subject to any such minimum purchase commitments, these 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.

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 addition, we may not continue to do business with our foundries on terms as favorable as our current terms. Significant risks
associated with our reliance on third-party foundries include:



| |  |  | consolidation in the industry leading to a change in control at key wafer suppliers;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | the lack of assured process technology and wafer supply;
| | - |  | --------------------------------------------------------



| |  |  | limited control over quality assurance, manufacturing yields and production costs;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | financial and operating stability of the foundries;
| | - |  | ---------------------------------------------------



| |  |  | limited control over delivery schedules;
| | - |  | ----------------------------------------



28



---

| |  |  | limited manufacturing capacity of the foundries; and
| | - |  | ----------------------------------------------------



| |  |  | potential misappropriation of our intellectual property.
| | - |  | --------------------------------------------------------

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 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 and weakening customer demand;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | subcontractors inability to transition to smaller package types or new package compositions;
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | a sudden, sharp increase in demand for semiconductor devices, which could strain the foundries or subcontractors manufacturing resources
and cause delays in manufacturing and shipment of our products;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | manufacturing quality control or process control issues, including reduced control over manufacturing yields, production schedules and product quality;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | disruption of transportation to and from Asia where most of our foundries and subcontractors are located;
| | - |  | ---------------------------------------------------------------------------------------------------------



| |  |  | political, civil, labor and economic instability;
| | - |  | -------------------------------------------------



| |  |  | embargoes or other regulatory limitations affecting the availability of raw materials, equipment or changes in tax laws, tariffs, services and freight
rates; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | compliance with local or international regulatory requirements.
| | - |  | ---------------------------------------------------------------

Other additional risks associated with subcontractors include:



| |  |  | subcontractors imposing higher minimum order quantities for substrates;
| | - |  | -----------------------------------------------------------------------



| |  |  | potential increase in assembly and test costs;
| | - |  | ----------------------------------------------



| |  |  | our board level product volume may not be attractive to preferred manufacturing partners, which could result in higher pricing or having to qualify an
alternative vendor;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | difficulties in selecting, qualifying and integrating new subcontractors;
| | - |  | -------------------------------------------------------------------------



| |  |  | entry into take-or-pay agreements; and
| | - |  | ----------------------------------------



| |  |  | limited warranties from our subcontractors for products assembled and tested for us.
| | - |  | ------------------------------------------------------------------------------------

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;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------



| |  |  | repurchasing shares of our common stock;
| | - |  | ----------------------------------------



| |  |  | announcements of merger or acquisition transactions; and/or
| | - |  | -----------------------------------------------------------



| |  |  | general global economic and capital market conditions.
| | - |  | ------------------------------------------------------

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 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 income tax returns. Our 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. 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.

On September 30, 2008, California enacted Assembly Bill 1452 which among other provisions, suspends net operating loss deductions
for our fiscal years 2009 and 2010 and extends the carryforward period of any net operating losses not utilized due to such suspension; adopts the federal 20-year net operating loss carryforward period; phases-in the federal two-year net operating
loss carryback periods beginning in fiscal year 2012 and limits the utilization of tax credits to 50 percent of a taxpayers taxable income.

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 integrated circuit 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 integrated circuits 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 may damage our facilities or those of our suppliers and customers.

Our corporate headquarters in Fremont, California is located near major earthquake faults that have experienced seismic activity. In
addition, some of our 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 headquarters, 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.

Fixed operating expenses and our 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.

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 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.

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, Germany, 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.

We also lease one additional building in California, totaling approximately 95,700 square feet, which is subleased to a tenant.
The sublease began on April 15, 2008 and expires 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

|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, datacom 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 global and
regional distributors with locations in thirty-three countries 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 are generally 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. Although foreign sales within certain countries or foreign sales comprised of certain
products may subject us to tariffs, our gross profit margin on international sales, adjusted for differences in product mix, is not significantly different from that realized on our sales to domestic customers. Our operating results are subject to
quarterly and annual fluctuations as a result of several 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). Neterion, based in Sunnyvale, California, was a supplier of differentiated 10 Gigabit Ethernet controller silicon and card solutions optimized for virtualized data centers. The acquisition of
Neterion allows us to couple our high performance, power efficient solutions for data security and network bandwidth optimization with Neterions industry leading virtualization technology to address the emerging 10 Gigabit Ethernet data center
infrastructure.

On June 17, 2009, we completed the acquisition of Galazar Networks Inc. (Galazar). Galazar,
based in Ottawa, Ontario, Canada, was a fabless semiconductor company focused on carrier grade transport over telecom networks. Galazars product portfolio addresses 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 fabless semiconductor company that was founded in 1996, spun off from Stac, Inc. in 1999 and traded on the NASDAQ under the symbol HIFN since 1999. The acquisition of Hifn expands and complements our product
offering in the enterprise



38



---

storage, networking and telecom markets where we have had a significant base of business for more than 10 years. The Hifn technology adds world class compression and data deduplication products
used in storage applications to optimize data and speed up data backup and retrieval. Hifn has also been a leading provider in security acceleration technology by providing encryption and compression products to the leading networking and telecom
system manufacturers.

On August 25, 2007, we completed the acquisition of Sipex Corporation (Sipex), a
company that designed, manufactured and marketed high performance, analog integrated circuits used by OEMs in the computing, consumer electronics, datacom and networking infrastructure markets.

In December 2007, we changed our fiscal year end from a fiscal year ending March 31 to fiscal years consisting of 52 or
53 weeks. In a 52-week year, each fiscal quarter consist of 13 weeks. The additional week in a 53-week year is added to the fourth quarter, making such quarter consist of 14 weeks. Fiscal year 2010, fiscal year 2009 and fiscal year 2008 are
comprised of 52-week periods. Fiscal years ended March 28, 2010, March 29, 2009 and March 30, 2008 are also referred to as 2010, 2009 and 2008 unless otherwise indicated.

EXECUTIVE SUMMARY

During fiscal year 2010, we completed the acquisitions of Hifn, Galazar and Neterion and introduced over 35 new products. We continued to
execute on our strategy of growing the company both organically and through acquisitions. Through the acquisitions of Hifn and Neterion, we now serve the significant Datacom and Storage market. Our investment in research and development reflects our
conscious effort to invest in new products to emerge stronger from the economic downturn. We believe we are well positioned for growth in the future.

With the assistance of employees with systems-level design experience and products acquired in our recent acquisitions, we are evolving
from a components supplier to a solutions provider to our customers. We believe our solutions will allow for systems-level sales and cross selling opportunities as we continue our focus on penetrating strategic customers while strengthening our
relationship with existing partners.

We have realigned our product lines to execute on our strategy of leveraging our
expertise in silicon integration, system architecture, and software to develop solutions to reduce, secure, optimize and transport data and to power and connect systems.

Our product lines of Communications, Datacom and Storage, Interface and Power are as follows:



| |  |  | Communications: Our legacy products in our T/E carrier and SDH/SONET product portfolios and products acquired in the acquisition of Galazar (Our
carrier Ethernet and OTN solutions);
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Datacom and Storage: Products acquired in the acquisition of Hifn (Our data security and compression, data deduplication solutions) and Neterion (Our
10 Gigabit Ethernet solutions);
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Interface: Our legacy UART products and our serial transceiver portfolio that was acquired in the Sipex acquisition in August 2007; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Power: Products acquired in the acquisition of Sipex (Our power conversion, systems controls, and LED lighting solutions), and
PowerXRour new programmable power product portfolio.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The economic downturn affected our communications product line significantly for the first time in the
September 2009 quarternine months later than our other products. We are now seeing a recovery and expect it to continue but at a slower quarterly sequential growth rate. Our interface and power products revenue have returned to their
pre-downturn run rates. We anticipate revenue growth to occur with our 10 Gigabit Ethernet products and our recently introduced programmable power products that are gaining traction in the marketplace.

As we enter fiscal 2011, we are aware of the challenges ahead of us and our industry. These include the macro-economic environment, the
European credit crisis and our continuous efforts to integrate our businesses

and deliver timely and quality products to our customersand retaining and attracting the talent to execute these efforts. We are both excited and cautiously optimistic about the upcoming
year.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The preparation of our financial statements and accompanying disclosures in conformity with GAAP, the accounting principles generally
accepted in the United States, 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 and long-lived assets and (6) 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 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. Allowances for sales returns and other reserves
are recorded based on historical experience or specific identification of an event necessitating an allowance.

Our actual
history of 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.



40



---

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 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.

Prior to August 25, 2007, the effective
date of the Sipex acquisition, our historical patterns of returns, pricing allowances and other concessions with distributors had been fairly consistent, which enabled us to reasonably estimate such allowances at the time of shipment. Therefore, we
historically recognized revenue on sales to all distributors on the sell-in basis and recorded an estimated allowance, at the time of shipment, based on authorized and historical patterns of returns and other concessions. Concurrent with the
acquisition of Sipex, we reassessed our expected ability to continue to reasonably estimate such allowances for each of our distributors as well as for Sipexs distributors. Prior to the acquisition, Sipex recognized revenue on sales to all
distributors on the sell-through basis. Consistent with Sipexs past practice, we concluded that we were not able to reasonably estimate such allowances at the time of shipment of products to Sipexs distributors. Therefore, we determined
that consistent with Sipexs past practice, we would continue to recognize sales to Sipexs distributors on the sell-through basis. In addition, as a result of the acquisition, our relationships, marketing and sales practices with our two
primary distributors had changed. Further, as disclosed in Part II, Item 8Financial Statements and Supplementary DataandNotes to Consolidated Financial Statements, Note 6 Related Party
Transaction, Our largest distributor, Future is a related party of Exar. As a result of these changes, we concluded that we could no longer reasonably estimate returns, pricing allowances and other concessions at the time of shipment of
products to these distributors. Accordingly, concurrent with our consummation of the Sipex acquisition on August 25, 2007, we determined it was appropriate that revenue on all sales to our two primary distributors, Future and Nu Horizons, be
recognized on the sell-through basis.

Software and Royalty Revenue Recognition

Software became an element of our revenue upon the acquisition of Hifn on April 3, 2009. Software license revenue is generally
recognized when a signed agreement or other persuasive evidence of an arrangement exists, vendor-specific objective evidence (VSOE) exists to allocate a portion of the total fee to any undelivered elements of the arrangement, the
software has been shipped or electronically delivered, the license fee is fixed or determinable and collection of resulting receivables is reasonably assured. At this time we do not have any multi element arrangements and, therefore, have not
established VSOE for multi element arrangements. Returns,



41



---

including exchange rights for unsold licenses, are recorded based on agreed-upon return rates or historical experience and are deferred until the return rights expire.

We recognize royalty revenue based on reported sales by third party licensees of products containing our materials and intellectual
property. The sublicense agreements are generally valid for a term of one year and include rights to unspecified future upgrades and maintenance during the term of the agreement. If there are extended payment terms, royalty revenue is recognized as
these payments become due. Non-refundable royalties, for which there are no further performance obligations, are recognized ratably over the term of the agreement.

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. 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.

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.

Uncertain Income Tax Provisions

Effective April 1, 2007, we adopted authoritative guidance addressing accounting for uncertainty in income taxes, which prescribes a
recognition threshold and measurement attribute for the financial statement recognition and measurement of uncertain tax positions taken or expected to be taken in our income tax return, and also provides guidance on derecognition, classification,
interest and penalties, accounting in interim periods, disclosure and transition.

Our total amount of gross unrecognized tax
benefits as of March 29, 2009 was $9.9 million. The unrecognized tax benefits increased by $6.0 million during the fiscal year ended March 28, 2010 to $15.9 million. If recognized, $13.5 million of these unrecognized tax benefits (net of
federal benefit) would be recorded as a reduction of future income tax provision before consideration of changes in valuation allowance.



42



---

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. Additionally, a change in the
estimated forfeiture rate will have a significant effect on reported stock-based compensation expense, as the effect of adjusting the rate for all unamortized expense after April 1, 2006 is recognized in the period the forfeiture estimate is
changed. 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 activities of our stock-based compensation.

In fiscal year
2007, our stockholders ratified the Exar Corporation 2006 Equity Incentive Plan (the 2006 Plan). Within the terms of the 2006 Plan, we now grant stock options and Restricted Stock Units (RSUs). At March 28, 2010,
unrecognized stock-based compensation was $8.1 million and $4.2 million for stock-options and RSUs, respectively, with remaining weighted average recognition periods of 2.91 years and 1.01 years, respectively.

Goodwill and Long-Lived Assets

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.

Our long-lived assets include land, buildings, equipment, furniture and fixtures and other intangible assets. 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.

Valuation of Business Combinations

We periodically evaluate strategic acquisitions that build upon our existing library of intellectual property, human capital and
engineering talent, and seek to increase our leadership position in the areas in which we operate.

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 the acquirer in the acquiree at their acquisition date fair value; and (iv) recognizing and measuring goodwill or a gain from a bargain purchase.



43



---

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 noncontrolling interest of the acquirer in
the acquiree. To the contrary, if the acquisition date fair value of identifiable assets acquired, the liabilities assumed, and any noncontrolling interest of the acquirer 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. 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 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 or abandoned, the useful life of the
IPR&D asset is determined and amortized accordingly.

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.

RESULTS OF OPERATIONS

On August 25, 2007, April 3, 2009, June 17, 2009 and March 16, 2010, we acquired Sipex, Hifn, Galazar and
Neterion, respectively. Accordingly, the results of operations of Sipex, Hifn, Galazar and Neterion have been included in our consolidated financial statements since August 26, 2007, April 4, 2009, June 18, 2009 and
March 17, 2010, respectively. We were precluded from recognizing net sales for products shipped to Sipexs, Hifn and Neterion distributors prior to the acquisition, and began to recognize revenue at those distributors once products shipped
to the distributors after the acquisition were sold to end customers. Also as described above in Critical Accounting Policies and Estimates, we began to recognize revenue on shipments to our two primary distributors, Future and Nu Horizons, on the
sell-through basis beginning August 26, 2007. Consequently, our net sales were lower until products shipped to those distributors after August 25, 2007 were sold to end customers.

Fiscal Year 2010 versus Fiscal Year 2009

Communication

Net sales of communication products, including network access and transmission products as well as network transport products from the
Galazar acquisition and optical products from the Sipex acquisition, for fiscal year 2010 decreased $3.7 million as compared to fiscal year 2009 and included $2.4 million of additional sales of Galazar products.

Excluding the additional Galazar sales, network access and transmission products for fiscal year 2010 decreased $6.2 million primarily
due to decreased customer demand for our SONET products, and a decrease in customer demand for our optical products related to end of life purchase in fiscal year 2009 with a resulting decrease in units sold.

Datacom and storage

Net sales of datacom and storage products include network access, transmission and storage products, as well as encryption, data reduction
and packet processing products from the Hifn acquisition and 10 Gigabit Ethernet controller silicon and card solutions from the Neterion acquisition. The $25.3 million in net sales in fiscal year 2010 includes $25.1 million in sales of Hifn products
and $0.2 million in sales of Neterion products.

Interface

Net sales of interface products, including UARTs, video, imaging and other products as well as transceiver products from the Sipex
acquisition, for fiscal year 2010 decreased $1.1 million as compared to fiscal year 2009 primarily due to price erosion on certain products.

Power Management

Net sales of power management products, including DC-DC regulators and LED drivers acquired from Sipex, 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.

Fiscal Year 2009 versus Fiscal Year 2008

Communication

Net sales of communication products, including network access and transmission products as well as optical products acquired from Sipex,
for fiscal year 2009 decreased $0.1 million as compared to fiscal year 2008.

Net sales of network access and transmission
products decreased $1.3 million primarily due to reduced customer demand and price erosion on certain SONET products, partially offset by a full years recognition of sales to our primary distributors on the sell-through basis of revenue
recognition. Net sales of optical products increased $1.2 million primarily due to the five additional months of combined results in fiscal year 2009.

Interface

Net sales of interface products, including UARTs, video, imaging and other products as well as transceiver products from the Sipex
acquisition, for fiscal year 2009 increased $13.1 million as compared to fiscal year 2008.

Net sales of UART products for
fiscal year 2009 decreased $5.1 million as compared to fiscal year 2008 primarily due to decreased customer demand and price erosion on certain products partially offset by a full years recognition of sales to our primary distributors on the
sell-through basis of revenue recognition. Net sales of transceiver products for fiscal year 2009 were $18.2 million higher as compared to fiscal year 2008 primarily due to the five additional months of combined results with Sipex in fiscal year
2009.

Power Management

Net sales of power management products, including DC-DC regulators and LED drivers acquired from Sipex, for fiscal year 2009 increased
$12.4 million as compared to fiscal year 2008 primarily due to the five additional months of combined results with Sipex in fiscal year 2009.

Net Sales by Channel

The net sales to our two primary distributors are shown in sell-through distributors, as per their current classification, despite $12.1
million in sales to them for the first five months of fiscal year 2008 being recorded on the sell-in basis of revenue recognition.

For fiscal years ended March 28, 2010, March 29, 2009 and March 30, 2008, approximately 35%, 44% and 35%,
respectively, of our net sales were derived from product sales to our two primary distributors, Future Electronics Inc. (Future) and Nu Horizons Electronics Corp. (Nu Horizons); and approximately 65%, 56% and 65%,
respectively, of our net sales were derived from sales to other distributors, OEM customers and other non-distributors.

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.
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 and included $26.6 million in sales
of Hifn, Galazar and Neterion products. Net of the acquired products, net sales decreased $5.6 million primarily due to lower sales of our legacy communications products.

Fiscal Year 2009 versus Fiscal Year 2008

Net sales to our distributors, for which we recognize revenue on the sell-through basis, for fiscal year 2009 increased by $27.3 million
primarily due to increased sales of the products acquired from Sipex of $25.7 million and a full years recognition of sales to our primary distributors on the sell-through basis of revenue recognition partially offset by reduced customer
demand.

Net sales to direct customers and other distributors for fiscal year 2009 decreased $1.9 million primarily due to
reduced customer demand and price erosion on a SONET product and certain UART products partially offset by increased sales of products acquired from Sipex of $6.1 million.

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, acquired intellectual property and capitalized IPR&D;
| | - |  | ------------------------------------------------------------------------------------------------------



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

Fiscal Year 2010 versus Fiscal Year 2009

Gross profit for fiscal year 2010 increased $13.1 million, or three percentage points as a percentage of net sales, 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 unabsorbed capacity, or 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.

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

Fiscal Year 2009 versus Fiscal Year 2008

Gross profit for fiscal year 2009 increased $10.1 million, but as a percentage of net sales decreased one percentage point, as compared to
fiscal year 2008. The decrease in gross profit as a percentage of sales was primarily due to an increase of $31.8 million in sales of lower gross margin products acquired from Sipex, higher charges of $1.2 million for excess and obsolete inventory,
a decrease of $5.1 million in sales of network and UART products that typically have higher gross margins, partially offset by lower amortization of acquired intangible assets and the sale last year of acquired inventory which had been written-up to
fair value.

We recorded impairment charges against purchased intangible assets in the third quarter of fiscal year 2009 and
in the fourth quarter of fiscal year 2008.

Stock-based compensation expense recorded in cost of sales was $0.6 million and
$0.4 million for fiscal year 2009 and 2008, respectively.

Research and
Development (R&D)

Our research and development costs consist primarily of:



| |  |  | the salaries, stock-based compensation, and related expenses of employees engaged in product research, design and development activities;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------



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

| |  |  | amortization of acquired intangible assets; and
| | - |  | -----------------------------------------------



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

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.

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 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 (RSU) grants made to former Hifn and Galazar employees 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.

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, development for our 10 Gigabit
Ethernet products, increased investment in software development, higher salaries due to additional employees from acquired companies, incentives, as we reach profitability, annual merit increases and fluctuations in reimbursements under a research
and development contract.

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

Fiscal Year 2009 versus Fiscal Year 2008

R&D-base expenses remained relatively flat as compared to fiscal year 2008. An increase in labor, equipment depreciation and patent
expenses associated with operating the entire fiscal year with the resources acquired from Sipex partially offset by lower EDA software license costs.

Stock-based compensation expense recorded in R&D expenses was $1.6 million as compared to $1.2 million for fiscal year 2008. The
increase in stock-based compensation expense as compared to the same period a year ago was primarily due to assumed options from the Sipex acquisition 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 2008 primarily relates to the
amortization of intangible assets associated with the Sipex acquisition.

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;

| |  |  | amortization of acquired intangible assets such as distributor relationships, tradenames/trademarks and customer relationships; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------



| |  |  | acquisition related costs.
| | - |  | --------------------------

Fiscal Year 2010 versus Fiscal Year 2009

SG&A-base expenses increased $5.5 million, or 16%, 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 RSU
grants made to former Hifn and Galazar employees and the incremental costs associated with the employee stock option exchange in November 2008.

Acquisition related costs 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.

Fiscal Year 2009 versus Fiscal Year 2008

SG&A-base expenses increased $2.9 million, or 9%, as compared to fiscal year 2008. The increase was primarily due to
increased labor, travel, insurance and subsidiary support expenses associated with operating the entire fiscal year with the resources acquired from Sipex partially offset by employee bonuses, audit and legal fees.

The decrease in stock-based compensation expense for fiscal year 2009 as compared to fiscal year 2008 was primarily attributable to
option forfeitures in 2009.

Acquisition related costs decreased $0.7 million as compared to fiscal year 2008. The decrease
reflects the exclusion of a completed acquisition in 2009.

We believe that selling, general and administrative expenses will
fluctuate as a percentage of sales and increase in absolute dollars due to, among other factors, salaries of employees from acquired companies, variable commissions, incentives as we reach profitability and annual merit increases.

Goodwill and Other Intangible Asset Impairment

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 the carrying value. Based on the results at the time of our analysis, the fair value exceeded the carrying value of our one reporting unit by 36%. As a result, no additional measurement was needed and no impairment was recorded for the fiscal
year ended March 28, 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 Goodwill and other intangible asset
impairment line item 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 Goodwill and other intangible asset impairment line item 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%.

The analysis determined that the carrying amount of the intangible assets exceeded the implied fair value under 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 Goodwill and other
intangible asset impairment line item 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.

Fiscal Year 2008

In the fourth quarter of fiscal year 2008, we conducted our annual impairment review and determined that, based on the then current market
conditions in the semiconductor industry and our stock price over the prior six months, the carrying amount of our goodwill exceeded its implied fair value under the test for impairment and recorded a goodwill impairment charge of approximately
$128.5 million, which is included in the Goodwill and other intangible asset impairment line item in the consolidated statements of operations. 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 and discount rates between 13% and 19%.

---

In the fourth quarter of fiscal year 2008, based on the then current market conditions in
the semiconductor industry and our stock price over the prior six months, certain intangible assets acquired in our acquisition of Sipex were tested for recoverability. As a result of an unfavorable product architecture decision by a market leading
end customer, our reassessment of potential product cost reductions and delay in introducing new proprietary products to market, we reduced our projections of our future cash flows and determined that the carrying amount of the purchased Sipex
intangible assets exceeded the implied fair value under the test for impairment and recorded an impairment charge of approximately $36.7 million, which is included in the Goodwill and other intangible asset impairment line item in the
consolidated statements of operations. Our estimate of the implied fair value of the intangible assets was based on the discounted value of estimated future cash flows over a six-year period with residual value and a discount rate of 13%.

Acquired In-Process Research and Development

We recorded a charge of $8.8 million in fiscal year 2008 in acquired In-Process Research and Development (IPR&D)
associated with our acquisition of Sipex in the three months ended September 30, 2007.

The IPR&D projects underway
at Sipex at the acquisition date were in the interface and power management product families. Within interface products, specific projects relate to new products in its multiprotocol and RS485 families. Within power management, development
activities relate to the commercialization of its digital power technology, LED drivers and DC-DC regulators and controllers. Of these projects, one of the three LED driver projects has been released to production and the remaining two were
cancelled. Two of the five DC-DC projects were released to production and the remaining three were cancelled. The sole digital power technology project has been released to production.

Interest Income and Other, Net

Interest income and other, net primarily consists of:



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



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



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



| |  |  | realized gains or losses on marketable securities; and
| | - |  | ------------------------------------------------------



| |  |  | gains or losses on the sale or disposal of equipment.
| | - |  | -----------------------------------------------------

Fiscal Year 2010 versus Fiscal Year 2009

The $2.1 million or 23% 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.



53



---

Fiscal Year 2009 versus Fiscal Year 2008

The $6.9 million or 43% decrease in interest income and other, net during fiscal year 2009 as compared to fiscal year 2008 was primarily
attributable to a decrease in interest income as a result of lower invested cash balances, as we repurchased 1.6 million of our shares of common stock for $13.4 million and lower yields and increased investment management fees as we
transitioned the internally managed portion of our portfolio to our professional investment managers, partially offset by increased sublease income. The sublease income is derived from a tenant who is a venture-backed, private company. If the
subtenant were to experience financial difficulties, our sublease income would be impacted and costs to return the leased facility to the landlord could increase.

Our Hillview facility located in Milpitas, California (the Hillview Facility), originally leased from Mission West
Properties, L.P., was sublet to a tenant in April 2008. The sublease expires on March 31, 2011 with average annual rent of approximately $1.4 million.

Interest expense

In fiscal year 2008, in connection with the acquisition of Sipex, we assumed a lease financing obligation related to the Hillview
Facility. We have accounted for this sale and leaseback transaction as a financing transaction which is included in the Long-term lease financing obligation line item on the consolidated balance sheet. The effective interest rate is
8.2%.

We have also acquired engineering design tools (design tools) under capital leases. We acquired $5.2
million of design tools in December 2007 under a four-year license, $3.7 million of design tools in November 2008 under a three-year license, $1.1 million in July 2009 under a 3-year license, and $1.3 million in December 2009 under a 28-month
license which were accounted for as capital leases and recorded in the Property, plant and equipment, net line item on the consolidated balance sheets. The related design tool obligations were included in the Long-term lease
financing obligations line item in our consolidated balance sheets. The effective interest rates for the design tools range from 4.0% to 7.25% for the four-year, three-year and 28-month tools.

Interest expense for the Hillview Facility lease financing and the design tools lease obligations for both fiscal years 2010 and 2009
totaled approximately $1.3 million. Interest expense for the Hillview Facility lease financing and the design tools lease obligations for fiscal year 2008 totaled approximately $0.7 million.

Impairment Charges on Investments

We periodically review our investments to assess whether any 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
and intent and ability to hold a security to maturity or forecasted recovery. Realized gains and losses and declines in value of our marketable investments judged to be other-than-temporary are reported in the Interest income and other,
net line item in the consolidated statements of operations. 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 other-than-temporary impairment charges of $0.6 million in fiscal year 2009.

Our long-term investments consist of the investments in TechFarm Ventures L.P. (TechFarm Fund) and Skypoint Telecom Fund II
(US), L.P. (Skypoint Fund). Both TechFarm Fund and Skypoint Fund are venture capital funds which invest primarily in private companies in the telecommunications and/or networking industry. We account for these non-marketable equity
securities under the cost method. We periodically review our



54



---

investments to assess whether they are other-than-temporarily impaired, in which case the investments are written down to their impaired value. Any decline in the value of our non-marketable
investments is reported in the Impairment charges on investments line item in the consolidated statements of operations.

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.

In fiscal year 2008, we did not record any impairment charges after our assessment of the valuation of the fund performance.

Skypoint 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.

In fiscal year 2008, we performed a review of our investments and determined that two of the portfolio companies in the Skypoint Fund had
limited cash on hand and financing opportunities were minimal. We concluded that a portion of the carrying value had been other-than-temporarily impaired and recorded a $0.6 million impairment charge during the year.

Provision for Income Taxes

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.

Fiscal Year 2008

Our effective tax rate for fiscal year 2008 was (4.3%). The provision for fiscal year 2008 differs from the amount computed by applying
the statutory federal rate of 35%. This difference is principally due to nondeductible goodwill impairment charges, the write-down of purchased intangible assets which is not deducted for tax purposes, and the impact of valuation allowance
against our deferred tax assets.

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;
| | - |  | --------------------------------------------------------



| |  |  | Provision for sales returns and allowances of $12.1 million;
| | - |  | ------------------------------------------------------------



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



| |  |  | Losses on investments of $0.3 million.
| | - |  | --------------------------------------

Working capital changes included:



| |  |  | a $17.2 million increase in accounts receivable primarily due to higher shipments;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | a $2.5 million increase in accounts payable primarily due to the increased number of vendors and related activity due to acquisitions; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a $4.2 million increase in deferred income and allowances on sales to distributors as our distributors have increased their inventory in response to
improving end customer demand.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our net inventories at March 28, 2010 were $15.0 million, compared with
$15.7 million at March 29, 2009. The decrease was primarily due to increased shipments partially offset by additional inventory required for Hifn, Galazar and Neterion products.

Investment ActivitiesIn fiscal year 2010, net cash used in investing activities includes acquisitions of Hifn,
Galazar and Neterion for $53.3 million, net purchases of short-term marketable securities of $5.4 million and $5.8 million in purchases of property, plant and equipment and intellectual property.

Financing ActivitiesIn fiscal year 2010, net cash used in financing activities reflects the $3.1 million repayment of
lease financing partially offset by $0.5 million of proceeds associated with our employee stock plans.

As of March 28, 2010, we were obligated to contribute our remaining committed capital
of approximately $0.5 million as required by the Skypoint Funds General Partner and in accordance with the partnership agreement between the Skypoint Fund and us. To meet our capital commitment to the Skypoint Fund, we may need to use our
existing cash, cash equivalents and marketable securities.

From time to time, we acquire outstanding shares of our common
stock in the open market to partially offset dilution from our equity awards, 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 established a share
repurchase plan (2007 SRP) and authorized the repurchase of up to $100 million of our common stock. During fiscal year 2010, we did not repurchase any of our common stock under the 2007 SRP. As of March 28, 2010, the remaining
authorized amount available under the 2007 SRP was $11.8 million with no termination date. We may continue to utilize our share repurchase plan, which would reduce our cash, cash equivalents and/or short-term investments 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 continue to finance our operations with 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.

As of March 28, 2010, asset-backed and
mortgage-backed securities, accounted for 9% and 23%, respectively, of our total investments in marketable securities of $206.2 million. These 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 sub-prime. As of the date of this 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. As of March 28, 2010, the net unrealized gain of our asset-backed and mortgage-backed securities totaled $0.4 million.

We believe that our cash and cash equivalents, short-term marketable securities and cash
flows from operations will be sufficient to satisfy working capital requirements, capital equipment and intellectual property needs for at least the next 12 months. However, should the demand for our products decrease in the future, the availability
of cash flows from operations may be limited, thus having a material adverse effect on our financial condition or results of operations. From time to time, we evaluate potential acquisitions, strategic arrangements and equity investments
complementary to our design expertise and market strategy, which may include investments in wafer fabrication foundries. To the extent that we pursue or position ourselves to pursue these transactions, we could consume a significant portion of our
capital resources or choose to seek additional equity or debt financing. Additional financing may not be available on terms acceptable to us or at all. The sale of additional equity or convertible debt could result in dilution to our stockholders.

RECENT ACCOUNTING PRONOUNCEMENTS

Please refer to Part II, Item 8Financial Statements and Supplementary DataandNotes to
Consolidated Financial Statements, Note 2  Accounting Policies.



|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 the fiscal years ended March 28, 2010 and March 29, 2009, 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 $206.2 million as of March 28, 2010 and $254.6 million as of March 29, 2009. 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 28, 2010, the increase or decline in the fair
value of the portfolio would not be material. At March 28, 2010, the difference between the fair market value and the underlying cost of the investments portfolio was a gross unrealized gain of $2.1 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 28, 2010, short-term investments consisted of asset and mortgage-backed securities, corporate bonds and government agency securities of $186.6 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 cash flows present fairly, in all material respects, the financial position of Exar Corporation and its subsidiaries at March 28, 2010 and March 29, 2009, and the results of their operations and
their cash flows for each of the three years in the period ended March 28, 2010 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 28, 2010, 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. 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.

As discussed in Note 3 to the consolidated financial statements, the Company changed the manner in which it accounts for business
combinations in fiscal year 2010

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.

EXAR CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

FISCAL YEARS ENDED MARCH 28, 2010, MARCH 29, 2009 AND MARCH 30, 2008

NOTE 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.
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, datacom 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.

On March 16, 2010, we completed the acquisition of Neterion, Inc. (Neterion). Neterion,
based in Sunnyvale, California, was a supplier of differentiated 10 Gigabit Ethernet controller silicon and card solutions optimized for virtualized environments. The acquisition of Neterion allows us to couple our high performance, power efficient
solutions for data security and network bandwidth optimization with Neterions industry leading virtualization technology to address the emerging 10 Gigabit Ethernet data center infrastructure.

On June 17, 2009, we completed the acquisition of Galazar Networks, Inc. (Galazar). Galazar, based in Ottawa, Ontario,
Canada, was a fabless semiconductor company focused on carrier grade transport over telecom networks. Galazars product portfolio addresses 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). Hifn was a provider of network and storage-security and data reduction products that simplify the way major network and storage original equipment manufacturers (OEMs), as well as small-and-medium enterprises
(SMEs), efficiently and securely share, retain, optimize, transport, access and protect critical data.

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In December 2007, we changed our fiscal year end from a fiscal year ending March 31 to
fiscal years consisting of 52 or 53 weeks. In a 52-week year, each fiscal quarter consist of 13 weeks. The additional week in a 53-week year is added to the fourth quarter, making such quarter consist of 14 weeks. Fiscal year 2010, fiscal year
2009 and fiscal year 2008 are comprised of a 52-week period. Fiscal years ended March 28, 2010, March 29, 2009 and March 30, 2008 are also referred to as 2010, 2009 and 2008 unless otherwise
indicated.

In December 2007, in connection with integrating and realigning our combined operations with Sipex, we reassessed
the economic facts and circumstances of each of our foreign subsidiaries and changed the functional currencies for our foreign subsidiaries to the U.S. dollar. Accumulated other comprehensive loss reported in the consolidated balance sheet before
December 1, 2007 related to the cumulative foreign currency translation adjustments of our subsidiaries prior to changing our functional currency was immaterial.

Foreign currency is 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 remeasured at the historical exchange rate. Revenues and expenses are remeasured at the average
exchange rates for the period.

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.

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 as other non-current assets.

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

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 item in the consolidated statements of operations.

Non-marketable equity investment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. 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 investment is recorded in the Impairment charges on investments line item 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 utilized the entity-wide approach to assess goodwill for impairment. During our annual goodwill impairment analysis in the fourth quarter of fiscal year 2010, the fair value exceeded
the carrying value and therefore 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 Goodwill and other intangible asset impairment line item in the consolidated statements of operations. During our annual goodwill impairment
analysis in the fourth quarter of fiscal year 2008, we recorded a $128.5 million impairment loss that was included in the Goodwill and other intangible asset impairment line item in the consolidated statements of operations. (See
Note 9Goodwill and Intangible Assets).

Long-Lived AssetsOur long-lived assets
include land, buildings, machinery and equipment, furniture and fixtures and other intangible assets. 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 against income equal to the excess of the carrying value over the assets fair value.

During fiscal
year 2010, no events or changes in circumstances suggested that the carrying amount for long-lived assets may not be recoverable and therefore no impairment was recorded.

In the third quarter of fiscal year 2009, the rapid and severe deterioration of worldwide economic conditions had 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 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 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. 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, 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. During the fourth quarter of fiscal year 2008, we recorded a $36.7 million impairment loss on our intangibles assets that was included in
the Goodwill and other intangible asset impairment line item in the consolidated statements of operations. (See Note 9Goodwill and Intangible Assets). Substantially all of our property, plant and equipment and
other long-lived assets are located in the United States.

Income TaxesDeferred taxes are recognized using
the asset and liability method, whereby deferred tax assets and liabilities are recognized for the future tax consequence attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their
respective tax base, and operating loss 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 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. For fiscal years ended
March 28, 2010, March 29, 2009 and March 30, 2008, approximately 35%, 44% and 35%, respectively, of our net sales were derived from product sales to our two primary distributors, Future and Nu Horizons; and approximately 65%, 56%
and 65%, respectively, of our net sales were derived from sales to other distributors, OEM customers and other non-distributors.

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 basis. 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.

Prior to August 25,
2007, the effective date of the Sipex acquisition, our historical patterns of returns, pricing allowances and other concessions with distributors had been fairly consistent, which enabled us to reasonably estimate such allowances at the time of
shipment. Therefore, we historically recognized revenue on sales to all distributors on the sell-in basis and recorded an estimated allowance, at the time of shipment, based on authorized and historical patterns of returns and other concessions.
Concurrent with the acquisition of Sipex, we reassessed our expected ability to continue to reasonably estimate such allowances for each of our distributors as well as for Sipexs distributors. Prior to the acquisition, Sipex recognized revenue
on sales to all distributors on the sell-through basis. Consistent with Sipexs past practice, we concluded that we were not able to reasonably estimate such allowances at the time of shipment of products to Sipexs distributors.
Therefore, we determined that consistent with Sipexs past practice, we will continue to recognize sales to Sipexs distributors on the sell-through basis. In addition, as a result of the acquisition, our relationships, marketing and sales
practices with our two primary distributors had changed. Further, as disclosed in Note 6Related Party Transaction, Future is a related party of Exar. As a result of these changes, we have concluded that we can no longer reasonably
estimate returns, pricing allowances and other concessions at the time of shipment of products to these distributors. Accordingly, concurrent with our consummation of the Sipex acquisition on August 25, 2007, we determined it was appropriate
that revenue on all sales to our two primary distributors, Future and Nu Horizons, be recognized on the sell-through basis.

Software and Royalty Revenue RecognitionSoftware became an element of our revenue upon the acquisition of Hifn on
April 3, 2009. Software license revenue is generally recognized when a signed agreement or other persuasive evidence of an arrangement exists, vendor-specific objective evidence (VSOE) exists to allocate a portion of the total fee
to any undelivered elements of the arrangement, the software has been shipped or electronically delivered, the license fee is fixed or determinable and collection of resulting receivables is reasonably assured. At this time we do not have any multi
element arrangements and, therefore, have not established VSOE for multi element arrangements. Returns, including exchange rights for unsold licenses, are recorded based on agreed-upon return rates or historical experience and are deferred until the
return rights expire.

We recognize royalty revenue based on reported sales by third party licensees of products containing
our materials and intellectual property. The sublicense agreements are generally valid for a term of one year and include rights to unspecified future upgrades and maintenance during the term of the agreement. If there are extended payment terms,
royalty revenue is recognized as these payments become due. Non-refundable royalties, for which there are no further performance obligations, are recognized ratably over the term of the agreement.

Software revenues have not been a significant part of our revenues.

Research and Development ExpensesResearch and development costs consist primarily of salaries, employee benefits,
mask tooling costs, depreciation, amortization, overhead, outside contractors and non-recurring engineering fees. Expenditures for research and development are charged to expense as incurred. In accordance with Financial Accounting Standards
Board (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 Exar defines 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, Exar has not capitalized any software development costs in fiscal years 2010, 2009 and 2008.

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 2010, Exar received $4.6 million 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 2010, 2009 and 2008 were not material.

Comprehensive Income (Loss)Comprehensive income (loss) includes charges or credits to equity as a result of foreign
currency translation adjustments, net of taxes, and unrealized gains or losses on marketable securities, net of taxes. Comprehensive income (loss) for fiscal years ended March 28, 2010, March 29, 2009 and March 30, 2008 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 remeasured 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 ended
March 28, 2010, March 29, 2009 and March 30, 2008.

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 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 2010, 2009 and 2008. 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. Alcatel-Lucent accounted for 11% of our net
sales in fiscal year 2008. No other OEM customer accounted for 10% or more of our net sales in fiscal years 2010, 2009 or 2008. Future, a related party, was and continues to be our largest distributor. Future, on a worldwide basis, represented 28%,
35% and 24% of net sales in fiscal years 2010, 2009 and 2008, respectively. Our second largest distributor, Nu Horizons, accounted for 11%, of net sales in fiscal year 2008. No other distributor accounted for 10% or more of our net sales for any of
the three fiscal years.

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 sub-contractors located in Asia. A significant disruption in the operations of one or more of these
sub-contractors 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.

FISCAL YEARS ENDED MARCH 28, 2010, MARCH 29, 2009 AND MARCH 30, 2008



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 28, 2010, March 29, 2009 and March 30, 2008 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 for purposes of the utilization of tax attributes.

Recent
Accounting Pronouncements

In September 2009, the FASBs Emerging Issues Task Force
(EITF) issued authoritative guidance addressing revenue arrangements with multiple deliverables. The guidance requires revenue to be allocated to multiple elements using relative fair value based on vendor-specific-objective-evidence,
third party evidence or estimated selling price. The residual method also becomes obsolete under this guidance. This guidance is effective for our interim reporting period ending on June 25, 2011. Early adoption is permitted. We are currently
evaluating the impact of the implementation of this guidance on our consolidated financial statements.

In September 2009,
FASBs EITF issued authoritative guidance addressing certain revenue arrangements that include software elements. This guidance states that tangible products with hardware and software components that work together to deliver the product
functionality are considered non-software products, and the accounting guidance under the revenue arrangements with multiple deliverables is to be followed. This guidance is effective for our interim reporting period ending on June 25, 2011.
Early adoption is permitted. We are currently evaluating the impact of the implementation of this guidance on our consolidated financial statements.

In June 2009, the FASB revised the authoritative guidance for the accounting for transfers of financial assets, which enhances
information reported to users of financial statements by providing greater transparency about transfers of financial assets, including securitization transactions, and where companies have continuing exposure to the risks related to transferred
financial assets. Additionally, on and after the effective date, the concept of a qualifying special-purpose entity is no longer relevant for accounting purposes and should be evaluated for consolidation by reporting entities. If the evaluation
results in consolidation, the reporting entity should apply the transition guidance provided, effective with the first annual reporting period that begins after November 15, 2009 and for interim and annual reporting periods thereafter. Early
adoption is prohibited. As of March 29, 2010, the first day of our fiscal year 2011, we adopted the new guidance for the accounting for transfers of financial assets and the adoption had no material impact on our financial position, results of
operations or liquidity.

In April 2010, the FASBs EITF issued new authoritative guidance addressing certain milestone
method of revenue recognition. The guidance provides the criteria that should be met for determining whether the milestone method of revenue recognition is appropriate. A vendor can recognize consideration that is contingent upon achievement of
a milestone in its entirety as revenue in the period in which the milestone is achieved only if the

milestone meets all criteria to be considered substantive. The following criteria must be met for a milestone to be considered substantive: (1) Be commensurate with either the level of
effort required to achieve the milestone or the enhancement of the value of the item delivered as a result of a specific outcome resulting from the vendors performance to achieve the milestone; (2) Related solely to past performance; and
(3) Be reasonable relative to all deliverables and payment terms in the arrangement. No bifurcation of an individual milestone is allowed and there can be more than one milestone in an arrangement. Accordingly, an arrangement may contain
both substantive and non-substantive milestones. This guidance is effective on a prospective basis for milestones achieved in fiscal years, and interim periods within those years, beginning on or after June 15, 2010. We are currently
evaluating the impact of the implementation of this guidance on our consolidated financial statements.

In January 2010, the
FASBs EITF issued new authoritative guidance addressing certain fair value measurements and disclosures. The guidance requires entities to provide new disclosures and clarify existing disclosures relating to fair value measurements. The
adoption of the new disclosures and clarifications of existing disclosures effective for interim and annual reporting periods beginning after December 15, 2009 had no material impact on our financial position, results of operations or
liquidity. We are currently evaluating the impact of implementing the disclosures about purchases, sales, issuances, and settlements in Level 3 fair value measurements on our consolidated financial statements, financial position, result of
operations or liquidity, which are effective for fiscal years beginning after December 15, 2010 and for interim periods within those fiscal years.

NOTE 3.    BUSINESS COMBINATIONS

We periodically evaluate strategic acquisitions that build upon our existing library of intellectual property, human capital and
engineering talent, and seek to increase our leadership position in the areas in which we operate.

Effective March 30,
2009, we adopted FASBs revised authoritative guidance for business combinations. 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 noncontrolling interest of Exar in the
acquiree. To the contrary, if the acquisition date fair value of identifiable assets acquired, the liabilities assumed, and any noncontrolling 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. 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. Neterion, a privately held company based in Sunnyvale, California, was a
supplier of 10 Gigabit Ethernet controller silicon and card solutions optimized for virtualized data centers. Neterions results of operations and estimated fair value of assets acquired and liabilities assumed were included in our consolidated
financial statements beginning March 16, 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, or deal costs, which are included in the Selling, general and administrative line item on the
consolidated statement of operations for the fiscal year ended March 28, 2010, were $0.5 million.

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. We will recognize additional assets or liabilities if new information is obtained about facts and circumstances that existed as of the acquisition date
that, if known, would have resulted in the recognition of those assets and liabilities as of that date. The measurement period shall not exceed one year from the acquisition date. Further, any associated restructuring activities will be expensed in
future periods. We have up to twelve months from the closing date of the acquisition to adjust pre-acquisition contingencies, if any. Severance costs of $0.1 million were recorded for the fiscal year ended March 28, 2010.

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.

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 value of existing technology, patents/core technology, IPR&D,
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 and 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%.

DevelopmentThe IPR&D project underway at Neterion at the acquisition date relates to the X3500 product series and to date has incurred approximately $2.9 million in expense. The total research and development expense expected to be
incurred to complete the project is estimated at $17.5 million, based on the project development timeline and resource requirements, and is scheduled for completion by December 2011. The percentage of completion for the project was estimated at 25%
at the acquisition date.

Acquisition of Galazar

On June 17, 2009, we completed the acquisition of Galazar. Galazar, based in Ottawa, Ontario, Canada, was a fabless semiconductor
company and software supplier focused on carrier grade transport over telecom networks. Galazars product portfolio addresses 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 expected to pay approximately $4.95 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 third fiscal quarter of fiscal year 2010 and $1.0 million was paid in cash. The additional $50,000 was expensed and included in the Research and
development line item on the consolidated statement of operations for the fiscal year ended March 28, 2010.

Acquisition-Related Costs

Acquisition-related costs, or deal costs, which are included in the Selling, general and administrative line item on the
consolidated statement of operations for the fiscal year ended March 28, 2010, were $0.9 million.

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. We will recognize additional assets or liabilities if new information is obtained about facts and circumstances that existed as of the acquisition date that, if
known, would have resulted in the recognition of those assets and liabilities as of that date. The measurement period shall not exceed one year from the acquisition date. Further, any associated

restructuring activities will be expensed in future periods. Subsequent to the acquisition, we recorded severance cost of $0.2 million for the fiscal year ended March 28, 2010.

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. We have up to twelve months from the
closing date of the acquisition to adjust pre-acquisition contingencies, if any.

The fair value allocated to each of the
major classes of tangible and identifiable intangible assets acquired and liabilities assumed of Galazar was as follows (in thousands):

We allocated the purchase price using established valuation techniques.

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.

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 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, IPR&D, customer relationships, order backlog and tradenames/trademarks 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 35%. The
discount rate used to value the existing intangible assets was 28%.

Acquired In-Process Research and
DevelopmentThe IPR&D project underway at Galazar at the acquisition date relates to the MXP2 product and to date has incurred approximately $2.3 million in expense. The total research and development expense expected to be incurred to
complete the project is estimated at $7.4 million, based on the project development timeline and resource requirements, and is scheduled for completion by July 2011. 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 all of the outstanding shares of Hifn. Hifn was a provider of network-and
storage-security and data reduction products that simplify the way major network and storage OEMs, as well as Small and Medium Enterprises (SMEs), efficiently and securely share, retain, access and protect critical data. 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, which are included in the Selling, general and administrative line item on the
consolidated statement of operations for the fiscal year ended March 28, 2010 were $3.8 million.

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. We will recognize additional assets or liabilities if new information is obtained about facts and circumstances that existed as of the acquisition date that, if known, would have resulted in
the recognition of those assets and liabilities as of that date. The measurement period shall not exceed one year from the acquisition date. Further, any associated restructuring activities will be expensed in future periods. Subsequent to the
acquisition, we recorded $983,000 in restructuring expenses for the fiscal year ended March 28, 2010, relating to severance and a building lease obligation in Los Gatos, California.

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 have up to twelve months
from the closing date of the acquisition to adjust pre-acquisition contingencies, if any.

The fair value allocated to each of
the major classes of tangible and identifiable intangible assets acquired and liabilities assumed on April 3, 2009 in the Hifn acquisition was as follows (in thousands):

We allocated the purchase price using established valuation techniques.

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,
research and development reimbursement contract, customer relationships, order backlog and tradenames/trademarks 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 to date have incurred approximately $2.6 million
and $1.1 million in costs, 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 are approximately $2.1 million and $0.7 million, respectively, based on project development timelines and resource requirements. The IPR&D project for flow through was completion in January 2010 and is in
production. The IPR&D projects for security processors are scheduled for completion by July 2010.

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 which are the following:

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.

discounts to interest income over the life of the investment. Our available-for-sale securities 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 which we intend to sell as necessary to meet our liquidity requirements.

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 within stockholders equity except those unrealized losses that are deemed to be other than temporary which are reflected in Impairment
charges on investments line item on the consolidated statements of operation.

Realized gains or losses on the sale of
marketable securities are determined on the specific identification method and are reflected in Interest income and other, net line item on the consolidated statements of operation. Net realized gains on marketable securities for fiscal
years ended March 28, 2010, March 29, 2009 and March 30, 2008, were $50,000, $578,000 and $174,000, respectively.

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 sub-prime. As of the date of this Form 10-K, 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. As of March 28, 2010, the net unrealized gain of our asset-backed and mortgage-backed securities totaled $400,000 or less than 0.2% of our total investments.

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 item 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 line item in the consolidated balance sheets. As of March 28, 2010, there was approximately $1.3 million of net unrealized gains 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 item in
the consolidated statements of operations. 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 our fiscal year ended March 29, 2009.

In the second quarter of fiscal year 2010, an asset-backed security 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.

The amortized cost and estimated fair value of cash equivalents and
marketable securities classified as available-for-sale at March 28, 2010 and March 29, 2009 by expected maturity were as follows (in thousands):

NOTE 6.    RELATED PARTY TRANSACTION

Affiliates of Future, Alonim Investments Inc. and two of its affiliates (collectively Alonim), own approximately
7.6 million shares, or approximately 17%, of our outstanding common stock as of March 28, 2010. As such, Alonim is our largest stockholder.

Our sales to Future are made under an agreement that provides protection against price reduction for its inventory of our products and
other sales allowances. We recognize revenue on sales to Future under a distribution agreement when Future sells the products to its end customers. Future has historically accounted for a significant portion of our net sales. It is our largest
distributor worldwide and accounted for 28%, 35% and 24% of our total net sales for fiscal years ended March 28, 2010, March 29, 2009 and March 30, 2008, respectively.

We reimbursed Future for approximately $8,000, $52,000 and $56,000 of expenses for marketing promotional materials for fiscal years ended
March 28, 2010, March 29, 2009 and March 30, 2008, respectively.

NOTE 7.    RESTRUCTURING

As part of the Hifn acquisition we assumed a lease obligation for the Hifn facility located in Los Gatos, California,
which expired in September 2009. As of September 27, 2009 there were no further lease payments due. In addition, we incurred severance expenses of $780,000 in connection with the Hifn acquisition.

As part of the Galazar acquisition we incurred severance cost of $100,000 for the fiscal year ended March 28, 2010.

FISCAL YEARS ENDED MARCH 28, 2010, MARCH 29, 2009 AND MARCH 30, 2008



In connection with the Sipex acquisition 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 current economic conditions. The Sipex restructuring costs were
accounted for as liabilities assumed as part of the business combination.

Our restructuring liabilities are included in the
Other accrued expenses line item in our consolidated balance sheets, and the activities affecting the liabilities for fiscal year ended March 28, 2010 are summarized as follows (in thousands):



|                          |  |               |      |   |                |   |    |                             |  |   |      |

The majority of the remaining facility related balance is expected to be paid during the remaining term of a
Sipex lease contract which extends through March 2012.

NOTE 8.    LONG-TERM INVESTMENTS

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 invested primarily in private companies in the telecommunications and/or networking industry. We account for this non-marketable equity investment under the cost method. We have periodically reviewed and determined 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 28,
2010 and March 29, 2009, reflecting the net of the capital contribution and the cumulative impairment charges.

As of
March 28, 2010 and March 29, 2009, our long-term investments balances, which are included in the Other non-current assets line item on the consolidated balance sheets were as follows (in thousands):



|              |  |               |       |               |   |

|              |  |               |       |               |   |      

We have made $4.5 million in capital contributions to
Skypoint Fund since we became a limited partner in July 2001. We contributed $41,000 and $227,000 to the fund during fiscal years of 2010 and 2009, respectively. As of March 28, 2010, we have a remaining potential capital commitment of
approximately $0.5 million should the general partner decide to request it.

The carrying amount of $1.4 million reflects the
net of the capital contribution, accumulative impairment charges and capital distributions. We received a capital distribution of $36,000 during fiscal year 2010. We did not receive any distribution during fiscal years 2009 and 2008.

Impairment

We analyzed the fair value of the underlying investments of Skypoint Fund and TechFarm Fund and concluded portions of the carrying value
were other-than-temporarily impaired and recorded impairments for fiscal years ended March 28, 2010, March 29, 2009 and March 30, 2008 as follows (in thousands):

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. 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 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 exceeded the carrying value of our one reporting unit by 36%. As a result, no additional measurement was needed and no impairment was recorded
for the fiscal year ended March 28, 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 Goodwill and other intangible asset impairment line item in
the consolidated statements of operations. During our annual goodwill impairment analysis in the fourth quarter of fiscal year 2008, we recorded a $128.5 million impairment loss that was included in the Goodwill and other intangible asset
impairment line item in the consolidated statements of operations. During fiscal year 2010, we added $3.1 million in goodwill as a result of the Hifn, Galazar and Neterion acquisitions. (See Note 3Business
Combinations).

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.

We performed a test of purchased intangible assets for recoverability in conjunction with our interim goodwill impairment test during the
fourth quarter of fiscal year 2010. 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
13%.

The analysis determined that the implied fair value under the test for impairment exceeded the carrying amount of the
intangible assets and therefore we did not record an impairment charge as a result of the analysis.

Given the current
volatile worldwide economic environment and the resulting uncertainties regarding its impact on our business, our estimates and assumptions regarding the duration of the ongoing economic downturn, or the period or strength of any future recovery,
made for purposes of our intangible asset impairment testing during the fourth quarter of fiscal year 2010 may prove to be inaccurate. If our assumptions regarding projected revenue or gross margin rates are not achieved, we may be required to
record additional intangible asset impairment charges in future periods, if any such change or other factor constitutes a triggering event. It is not possible at this time to determine if any such future impairment charge would result or, if it
does, whether such charge would be material. As of March 28, 2010 there were no indicators that required us to extend our intangible assets impairment review we performed in conjunction with our interim goodwill impairment test during the
fourth quarter of fiscal year 2010 and therefore we did not record an impairment charge during fiscal year 2010.

During
fiscal year 2009, 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 Goodwill and other intangible asset impairment line item 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.

In the fourth quarter of fiscal year 2008, based on the then current market conditions in the semiconductor industry and our
stock price over the prior six months, certain intangible assets acquired in our acquisition of Sipex were tested for recoverability. As a result of an unfavorable product architecture decision by a market leading end customer, our reassessment of
potential product cost reductions and delay in introducing new proprietary products to market, we reduced our projections of our future cash flows and determined that the carrying amount of the purchased Sipex intangible assets exceeded the implied
fair value under the test for impairment and recorded an impairment charge of approximately $36.7 million, which is included in the Goodwill and other intangible asset impairment line item in the consolidated statements of operations.
Our estimate of the implied fair value of the intangible assets was based on the discounted value of estimated future cash flows over a six-year period with residual value and a discount rate of 12.5%.

NOTE 10.    LOSS PER SHARE

Basic 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 issue common stock were exercised for common stock, using the treasury stock
method, and the common stock underlying restricted stock units (RSUs) were issued.

For fiscal year ended March 28, 2010, as we incurred a net loss, the weighted average number of common
shares outstanding equaled the weighted average number of common shares and common share equivalents assuming dilution. Options to purchase common shares and RSUs for common shares in the aggregate amount of approximately 337,000 shares for the
period ended March 28, 2010 were excluded from our loss per share calculation under the treasury stock method. Had we had income for these periods, our diluted shares would have increased by the aforementioned amount.

For fiscal year ended March 28, 2010, options to purchase approximately 4.8 million shares of common stock, at exercise prices
ranging from $7.08 to $86.10, were outstanding but would not have been included in a computation of diluted loss per share because they were anti-dilutive under the treasury stock method. Approximately 280,000 warrants outstanding were also excluded
from the computation of diluted loss per share because they were anti-dilutive under the treasury stock method for fiscal year ended March 28, 2010. Unvested restricted stock units of 3,445 with a grant date fair value of $7.03 were outstanding
as of March 28, 2010 and were not included in the computation of diluted net loss per share because they were anti-dilutive under the treasury stock method.

For fiscal year ended March 29, 2009, as we incurred a net loss, the weighted average number of common shares outstanding equaled
the weighted average number of common shares and common share equivalents assuming dilution. Options to purchase common shares and RSUs for common shares in the aggregate amount of approximately 214,000 shares for the period ended March 29,
2009 were excluded from our loss per share calculation under the treasury stock method. Had we had income for these periods, our diluted shares would have increased by the aforementioned amount.

For fiscal year ended March 29, 2009, options to purchase approximately 4.5 million shares of common stock, at exercise prices
ranging from $5.44 to $86.10, were outstanding but would not have been included in a computation of diluted loss per share because they were anti-dilutive under the treasury stock method. Approximately 280,000 warrants outstanding were also excluded
from the computation of diluted loss per share because they were anti-dilutive under the treasury stock method for fiscal year ended March 29, 2009. Unvested restricted stock units of 56,000 with a grant date fair value of $7.12 were
outstanding at March 29, 2009 and were not included in the computation of diluted net loss per share because they were anti-dilutive under the treasury stock method.

FISCAL YEARS ENDED MARCH 28, 2010, MARCH 29, 2009 AND MARCH 30, 2008



For fiscal year ended March 30, 2008, as we incurred a net loss, the weighted
average number of common shares outstanding equaled the weighted average number of common and common share equivalents assuming dilution. Options to purchase common shares and RSUs for common shares in the aggregate amount of approximately 405,000
shares for the period ended March 30, 2008 were excluded from our loss per share calculation under the treasury method. If we had income for the period, our diluted shares would have increased by the aforementioned amount.

For fiscal year ended March 30, 2008, options to purchase approximately 5.2 million shares of common stock, at exercise prices
ranging from $8.78 to $86.10, were outstanding but would not have been included in a computation of diluted loss per share because they were anti-dilutive under the treasury stock method. Approximately 280,000 warrants outstanding were also excluded
from the computation of diluted loss per share because they were anti-dilutive under the treasury stock method for fiscal year ended March 30, 2008. Unvested restricted stock units of 37,901 with a grant date fair value of $11.39 were
outstanding at March 30, 2008 and were not included in the computation of diluted net loss per share because they were anti-dilutive under the treasury stock method.

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. We may continue to utilize the share repurchase plan, which would reduce our cash, cash equivalents and/or short-term investments
available to fund future operations and to meet other liquidity requirements.

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. The 2007 SRP was in addition to a share repurchase plan announced in March 6, 2001 (2001 SRP), which
covered the repurchase of up to $40 million of our common stock.

A summary of our stock repurchases for the three fiscal
years of 2010, 2009 and 2008 was as follows (in thousands):

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 were $0.5
million, $0.4 million and $0.3 million for fiscal years ended March 28, 2010, March 29, 2009 and March 30, 2008, respectively.

Executive and Employee Incentive Compensation Programs

Our incentive compensation programs provide for incentive awards for substantially all employees based on the achievement of personal
objectives and our operating performance results. During fiscal years ended March 28, 2010, March 29, 2009 and March 30, 2008, we paid approximately $118,000, $468,000 and $699,000 in incentive compensation, respectively. Unpaid
incentive compensation at March 28, 2010, March 29, 2009 and March 30, 2008 was approximately $118,000, $300,000 and $600,000, respectively. Our incentive compensation programs may be amended or discontinued at the discretion of
our board of directors.

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.

We are
authorized to issue 4.5 million shares of common stock under our ESPP. At March 28, 2010 and March 29, 2009, 1,549,162 and 1,607,697 shares of common stock, respectively, were authorized and reserved for future issuance under our
ESPP.

A summary of shares issued to participating employees for the three fiscal years of 2010, 2009 and 2008 was as follows:



|                                  |  |                       |  |                      |

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 vesting and partial vesting based upon level of performance. Grants under the Sipex Plans are only available to former Sipex employees or employees of
Exar hired after the Sipex acquisition. At March 28, 2010, there were 1.7 million shares available for future grant under all our equity incentive plans.

As of March 28, 2010 and March 29, 2009, there were options to purchase approximately 5.3 million and 3.4 million
shares of our common stock outstanding under all stock option plans, respectively.

The following table summarizes information

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.

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 vest 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 RSUs is as follows:

|(1) | The aggregate intrinsic value of RSUs represents the closing price per share of our common stock at the end of the periods presented, multiplied by the number of
unvested RSUs or the number of vested and expected to vest RSUs, as applicable, at the end of each period.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(2) | For RSUs, stock-based compensation expense was calculated based on our stock price on the date of grant, multiplied by the number of RSUs granted. The grant date fair
value of RSUs, less estimated forfeitures, was recognized on a straight-line basis, over the vesting period.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In
July 2009, we granted performance-based RSUs covering 99,000 shares to certain executives, issuable upon meeting certain performance targets in our fiscal 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 2010, $368,000 of compensation expense was recorded to reflect the achievement of these performance targets.

During fiscal year 2008, we granted performance-based RSUs covering approximately 22,000 shares to certain executives, issuable on
March 31, 2008. Based on our assessment of meeting the performance targets established for each individual and the probability that these targets will be achieved, we recorded approximately $135,000 of compensation expense related to these
grants for the year ended March 30, 2008. No such grants were made in fiscal year 2009.

Stock-Based Compensation Expenses

The following table summarizes stock-based compensation expense related to stock options and RSUs for fiscal years ended
March 28, 2010, March 29, 2009 and March 30, 2008 (in thousands):

The amount of stock-based compensation cost
capitalized in inventory was not material at each of the fiscal year ends presented.

During fiscal year 2008, we modified
options to purchase approximately 298,000 shares held by our former chief executive officer and one other officer upon their departures in December 2007 and February 2008, respectively. The modification provided an extended exercise period of six
months following termination as compared to three months as defined by the plan. As a result of the modifications, we recorded additional stock-based compensation expenses of approximately $18,000 during fiscal year ended March 30, 2008.

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,

FISCAL YEARS ENDED MARCH 28, 2010, MARCH 29, 2009 AND MARCH 30, 2008



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 will be amortized over the two years service period. During fiscal years 2010 and 2009, we recorded
approximately $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 are 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 expire on May 18, 2011. As of March 28, 2010, the warrants had not been exercised and remained outstanding.

NOTE 15.    LEASE FINANCING OBLIGATION

In connection with the Sipex acquisition, we assumed a lease financing obligation related to the Hillview Facility. The lease term expires
in March 2011 with 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 item 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 item on our consolidated balance sheet. The effective interest rate is 8.2%. Depreciation for the Hillview Facility was
recorded over the straight-line method for the remaining useful life and was $0.4 million, $0.4 million and $0.2 million in fiscal years 2010, 2009 and 2008, respectively. At the end of the lease term, the estimated final lease obligation is
approximately $12.2 million, which we will settle by returning the Hillview Facility to the lessor.

For both fiscal years
2010 and 2009, interest expense totaled approximately $1.1 million, for the Hillview Facility lease financing obligation.

We sublet the Hillview Facility in April 2008. The sublease expires in March 2011 and we
expect annual sublease income of approximately $1.5 million for the duration of the sublease term. The sublease income of $1.4 million for fiscal year 2010 was recorded in the Interest income and other, net line item in our condensed
consolidated statements of operations.

We have also acquired engineering design tools (design tools) under
capital leases. We acquired $5.2 million of design tools in December 2007 under a four-year license, $3.7 million of design tools in November 2008 under a three-year license, $1.1 million in July 2009 under a 3-year license, and $1.3 million in
December 2009 under a 28-month license which were accounted for as capital leases and recorded in the Property, plant and equipment, net line item on the consolidated balance sheets. The related design tool obligations were included in
the Long-term lease financing obligations line item in our consolidated balance sheets. Amortization on the design tools is recorded using the straight-line method over the remaining useful life and was $2.9 million, $1.6 million and
$0.3 million, respectively, for fiscal years 2010, 2009 and 2008.

obligations as of March 28, 2010 were as follows (in thousands):

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 such, we accrued an additional $58,000, increasing our liability to $250,000. This accrual includes approximately $200,000 for various
remediation options under consideration and $50,000 for future annual monitoring. As of March 28, 2010 the outstanding liability was $137,000, net of payments of $113,000, during fiscal year 2010.

Sipex, which we acquired in August 2007, entered into a definitive Master Agreement with Hangzhou Silan Microelectronics Co. Ltd. and
Hangzhou Silan Integrated Circuit Co. Ltd. (collectively Silan) in China. Silan is

a China-based semiconductor foundry. This transaction was related to the closing of Sipex wafer fabrication operations located in Milpitas, California. Under this agreement, Sipex and Silan would
work together to enable Silan to manufacture semiconductor wafers using Sipex process technology. The Master Agreement includes a Process Technology Transfer and License Agreement which contemplates the transfer of eight of our processes and related
product manufacturing to Silan. Subject to our option to suspend in whole or in part, there is a purchase commitment under the Wafer Supply Agreement obligating us to purchase from Silan an average of at least one thousand equivalent wafers per
week, calculated on a quarterly basis, for five years beginning February 2006. There were open purchase orders for approximately $3.3 million outstanding as of March 28, 2010.

Generally, we warrant all of our products against defects in materials and workmanship for a period of 90 days and occasionally we may
provide an extended warranty of up to three years from the delivery date. 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 liability related to our products was immaterial at the end of fiscal year 2010.

In the ordinary
course of business, we may provide indemnification of varying scope and terms to customers, vendors, lessors and 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 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. There are no
pending legal proceedings to which the Company, any director, officer or affiliate of the Company is a party to.

Consolidated pre-tax income included foreign income of $2.4 million, $212,000 and $218,000 for the fiscal
years ended March 28, 2010, March 29, 2009 and March 30, 2008, respectively. Undistributed earnings of $3.7 million of our foreign subsidiaries are considered to be indefinitely reinvested and, accordingly, no provision for federal
and state income taxes have been provided thereon. Upon distribution of those earnings in the form of a dividend or otherwise, we would be subject to both United States income taxes (subject to an adjustment for foreign tax credits) and withholding
taxes payable to various foreign countries.

As of March 28, 2010, our federal and state net operating loss carryforwards for income tax purposes
were approximately $269.2 million and $130.2 million, respectively. If not utilized, $53,000 of the federal net operating loss carryovers will begin to expire in fiscal year 2019, while the state net operating losses will begin to expire in 2011.
Additionally, we have no capital loss carryforwards as of March 28, 2010.

As of March 28, 2010, our federal and
state tax credit carryforwards were $9.3 million and $15.8 million, respectively. Federal and state credits will begin to expire in fiscal years 2012 and 2010, respectively. 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 $10.3 million of these deferred tax assets pertain to certain net operating loss and credit carryforwards resulting 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

Effective April 1, 2007, we adopted authoritative guidance addressing Accounting for Uncertainty in Income Taxes, which prescribes a
recognition threshold and measurement attribute for the financial statement recognition and measurement of uncertain tax positions taken or expected to be taken in our income tax return, and also provides guidance on derecognition, classification,
interest and penalties, accounting in interim periods, disclosure and transition.

million. The unrecognized tax benefits increased by $6.0 million during the fiscal year ended March 28, 2010 to $15.9 million. If recognized, $13.5 million of these unrecognized tax benefits (net of federal benefit) would be recorded as a
reduction of future income tax provision before consideration of changes in valuation allowance.

A reconciliation of the
beginning and ending amount of the unrecognized tax benefits during the tax year ended March 28, 2010 is as follows (in thousands):

|Unrecognized tax benefits as of March 28, 2010       |  | $      | 15,863 |

Of the total unrecognized gross tax benefit of $15.9 million, $3.2 million is presented within income taxes
payable, non-current, and $12.7 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. The total amount of unrecognized tax
benefit (net of federal benefit), if recognized would affect the effective rate is $13.5 million before consideration of change in valuation allowance.

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 $0.4 million and $0.3 million as of March 28, 2010 and March 29, 2009, respectively.

Our only major tax jurisdictions are the United States federal and various states. The fiscal years 2001 through 2009 remain open and
subject to examinations by the appropriate governmental agencies in the United States and certain of our state jurisdictions.

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).

|ITEM 9A. | CONTROLS AND PROCEDURES
|-------- | -----------------------

Disclosure
Controls and Procedures

Evaluation of Disclosure Controls and Procedures (Disclosure
Controls).    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 Report on Form 10-K. This Evaluation was performed under the supervision and with the participation of management, including our Chief Executive Officer (the CEO), as principal executive officer, and Chief Financial Officer (the
CFO), as principal financial officer.

Attached as Exhibits 31.1 and 31.2 of this Report on Form 10-K are the
certifications of the CEO and the CFO, respectively, in compliance with Section 302 of the Sarbanes-Oxley Act of 2002 (the Certifications). This section of the Report provides information concerning the Evaluation referred to in the
Certifications and should be read in conjunction with the Certifications.

Disclosure Controls are controls and procedures
designed to ensure that information required to be disclosed in the reports filed or submitted under the Securities Exchange Act of 1934, as amended, 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 Securities Exchange Act of 1934, as amended, to
our management, including the CEO and CFO, to allow timely decisions regarding required disclosure.

Based on the Evaluation,
our CEO and CFO have concluded that our Disclosure Controls are effective as of the end of fiscal year 2010.

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 29, 2010 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 28, 2010, 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.

Our independent registered public accounting firm has
audited the financial statements included in Part II, Item 8Financial Statements and Supplementary Data of this report and has issued an attestation report on our internal control over financial reporting.

Changes in Internal Control over Financial Reporting

We completed our acquisitions of Hifn on April 3, 2009, Galazar on June 17, 2009 and Neterion on March 16, 2010 and
integrated Exars, Hifns, Galazars and Neterions internal controls and procedures as of this Report on Form 10-K.

There was no change in our internal control over financial reporting that occurred during the fourth quarter of fiscal year 2010 that has
materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
