ITEM 1. BUSINESS

OVERVIEW

Exar Corporation and its subsidiaries (“Exar” or “we”) is a fabless semiconductor company that designs, develops, markets and sells connectivity and power management products to the consumer, communications and industrial markets. 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 system and industrial automation equipment. Our portfolio spans a wide range of performance solutions from direct current to direct current (“DC-DC”) regulators and controllers, voltage references, microprocessor supervisors, charge pump regulators and light-emitting diode (“LED”) drivers, single and multi-channel Universal Asynchronous Receiver/Transmitter (“UART”) for portable and wireless applications, serial interface, port multipliers for storage applications, to T/E (T: North America and Asia transmission interface; E: European transmission interface) and Synchronous Optical Network/Synchronous Data Hierarchy (“Sonet/SDH”) communications. The solutions are designed working directly with large original equipment manufacturer (“OEM”) customers who help drive our technology roadmap and system solutions.

We were incorporated in California in 1971 and reincorporated in Delaware in 1991. Our common stock trades on The NASDAQ Global Market (“NASDAQ”) under the symbol “EXAR”. See the information in Part II, Item 8—“Financial Statements and Supplementary Data” for information on our financial position as of March 30, 2008 and March 31, 2007, and our results of operations and cash flows for the fiscal years ended March 30, 2008, March 31, 2007 and March 31, 2006.

In August 2007, we completed our merger with Sipex Corporation (“Sipex”), a company that designed, manufactured and marketed high performance, analog integrated circuits (“IC”) used by OEMs in the computing, consumer electronics, communications and networking infrastructure markets. As a result of the merger, we have combined product offerings and increased technical expertise, distribution channels, customer base and geographic reach.

3

We believe our broad product offerings provide our customers the following benefits:

• A single source supplier for a broad range of connectivity solutions and power management products which include transceivers, mappers, framers, UARTs, PowerBlox regulators and display drivers;

• Unique value-added features and functions;

• Highest power density solutions with lowest power consumption, and at elevated operating temperatures through unique intellectual property and the integration of multiple functions on a single device;

• Reduced system noise jitter and improved data integrity; and

• Accelerated time-to-market by enabling our customers to focus on their core competencies and to outsource standards-based solutions.

Our key elements of the solutions include:

Commitment to Connectivity.    We remain steadfast in our commitment to connectivity—a strategic principle that drives our product strategies and serves as a foundation for customer and vendor engagements. Connectivity describes our distinctive approach in creating and providing value to our stockholders, customers and suppliers.

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. For example, our high-speed, low-jitter Phase-Locked-Loop (“PLL”) capability plays a key role in our mixed-signal line interface units, transceivers, timing recovery, jitter attenuators and mapper products. In addition, we have developed many digital blocks and engines that are used in framers, mappers, cross connects and aggregation functions. For our core analog capability, we have developed the first DC-DC switching solution delivering the highest power density in the smallest size and operating at the highest temperature levels without a heat-sink. As a result, we can provide our customers with solutions that typically exceed standard specifications and allow them flexibility in designing other system elements.

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. We believe that by using our solutions, OEMs can develop higher performance systems, better leverage their development resources and reduce their time-to-market.

Compelling Performance Solutions.    We use our systems expertise and our analog, digital and mixed-signal design techniques to architect high-performance products based on standard complementary metal oxide semiconductor (“CMOS”) process technologies. The diversity of our technology allows us to integrate in order to develop further unique and differentiated solutions for our customers.

MARKETS AND PRODUCTS

Communications

The communications industry and its underlying technology continue to go through a significant transformation. This transformation has been largely driven by the continuing adoption of broadband applications such as the internet, voice over internet protocol (“VOIP”) and video-on-demand, resulting in increased demand for bandwidth, storage capacity and security. This phenomenon has a significant influence on the type and configuration of equipment deployed in the communications infrastructure, requiring carriers to invest in multi-service equipment that can aggregate and transport these varying types of network traffic.

For several years, the communications industry has also been experiencing consolidation as surviving carriers acquire wire-line and wireless networks to compete with expanded coverage and services, while

4

demanding significant reductions in the cost of building and maintaining these networks. The combined effect of these changes in the telecommunications market continues to drive IC manufacturers to increase the bandwidth supported by their devices by providing vertical integration (more functionality) and horizontal integration (more channels). In addition, heat and power have become problematic issues in these applications. Increasingly, the solution requires the power management portion of the system to work in alignment with the data processing solution in order to reduce overall system power and heat. This push to providing more cost effective devices while reducing the power and heat is enabling the increased adoption rate of these services in both established and emerging markets. We believe that IC companies, such as Exar, with proven analog and digital design expertise and a deep understanding of system-level applications will have a competitive advantage in this changing market environment.

Our products for T/E carrier, ATM and SONET/SDH applications include high-speed analog, digital and mixed-signal physical interface and access control ICs. The physical interface IC consists of a transmitter and receiver that, when integrated, is called a transceiver. Transceivers interface with the physical transmission media. Most of these high-speed, mixed-signal ICs convert digital inputs in a parallel format into a single bit stream that is many times faster than the original signal. Access control circuits are digital circuits that format, or frame, the data, perform error checking, and in some applications, aggregate signals by mapping multiple lower-speed data streams into one single higher-speed stream. The figure below illustrates where our products are employed within networking equipment.

Our communications products include analog front ends (“AFEs”), transmitters, receivers, transceivers (also known as line interface units or “LIUs” or “PHYs”), jitter attenuators, framers, ATM UNIs and data aggregation mappers. These products are used in networking equipment such as SONET/SDH Add/Drop Multiplexers (“ADMs”), PBX, central office switches, digital cross connects, multi-service provisioning platforms, routers and Digital Subscriber Loop Access Multiplexes (“DSLAMs”).

T/E & SONET/SDH

While the worldwide communications infrastructure market continues to transform into packet based infrastructure to support cost and service demands imposed by the deployment of new converged services, many of the existing networks continue to be powered by T/E and SONET/SDH based infrastructure. Our communications products primarily address equipment markets in two main segments: Metro-Access and Metro-Core. The Metro-Access segment of the communications network covers both wired and wireless access equipment that aggregates data traffic from homes, wireless base-stations and businesses towards the Metro-Core. The Metro-Core communications network primarily consists of fiber-optics based equipment that

5

transports data at rates of 2.4 Gigabits per second or higher within a city center or a larger area. In North America, the high-speed data traffic standard is SONET and in most of the rest of the world, it is SDH. Over optical fiber, the SONET/SDH standard ensures network reliability, data integrity and the interoperability of equipment deployed across the network from different manufacturers.

We offer a broad range of products in the T1/E1 segment encompassing AFEs, short-haul and long-haul LIUs and LIU/framer combinations that incorporate reconfigurable, relayless, redundancy with integrated termination resistors and jitter attenuators. Used individually or in chip sets, our T1/E1 devices 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 LIU combination products simplify the design process by saving board space and by reducing complexity as a result of lowering component count. Our T1/E1 portfolio includes products with up to 21 channels of AFEs, up to 14 channels LIU/JA, up to 8 channels LIU/framer and up to 28 channel LIU/framer/mapper combinations.

We have developed a diversified portfolio of single/multi-channel T3/E3 physical interface solutions with integrated transceivers and jitter attenuators that achieve high performance levels while reducing board space and overall power in multi-port applications. Extending our jitter attenuation capabilities, we incorporate desynchronization in our transceivers and data aggregation mappers to solve complex timing issues associated with mapping/demapping from SONET/SDH (synchronous) to T3/E3 (asynchronous) environments. In addition, we have integrated our LIU and framer functions into our multi-channel DS3/E3 LIU/Framer/JA combination devices that offer customers additional design flexibility.

Our strategy is to accelerate the reduction of power consumption and integrate the normally separate power and communications functions in order to significantly reduce power consumption and overall heat generation.

We also supply a family of V.35 transceiver products used for data transmission, primarily in networking equipment such as routers and bridges.

Our data aggregation mapper solutions leverage our expertise in T/E carrier with SONET/SDH, enabling us to provide unique solutions to the SONET/SDH marketplace. In addition to integrating SONET PHY capability into our data aggregation mappers, we also offer a family of OC-3/12/48 PHYs and intend to complement these devices with additional OC-48 data aggregation solutions. Our access control products include framers, ATM UNIs and data aggregation mappers. Complementing our OC-3 to OC-48 SONET/SDH devices was the addition of a highly integrated OC-3/STM-1 to OC-192/STM-64 multi-rate framer. This product extends our SONET/SDH capabilities to cover all data rates starting from OC-3/STM-1 to OC-192/STM-64. In addition, the device enables significant flexibility in line card design coupled with substantial cost and power savings. We extended our mixed-signal technology leadership into next generation metro core and transport network markets with the introduction of the first in a family of multi-protocol over SONET/SDH framers. These devices are designed to facilitate the growing market shift towards the convergence of triple-play services over SONET/SDH.

Consumer/Industrial

In the consumer and industrial space, we provide our storage, interface, and power solutions. For the consumer markets, we focus on the high performance consumer segment such as digital video recorders, set-top boxes, liquid crystal display (“LCD”) and plasma high-definition TVs and gaming. In the industrial market, we focus in areas such as system automation, robotics and medical and test devices in both tethered and portable applications.

Serial Communications

The transition from parallel to serial interfaces for chip-to-chip or system-to-system interconnects has been required to address the needs of the fastest-growing data communications markets. By converting parallel links

6

into serial links, UARTs play a vital role in reducing the large number of wires and traces in legacy designs. In addition to this conversion, UARTs offer additional benefits by off loading functions such as interrupt processing and data flow control from the CPU, which results in increased bandwidth.

UARTs are used in a wide range of equipment for control and diagnostics functions. UARTs are also used in system management to monitor Quality of Service (“QoS”) information, or to provide redundancy in fault tolerant systems. Our highly integrated single/multi-channel UARTs have been specifically designed for systems with high throughput. These include servers, routers, network management equipment, computer telephony, remote access servers, wireless base stations and repeaters.

Multi-channel UARTs are commonly used in industrial applications such as process control and factory automation. Point-of-sale host systems often communicate to multiple remote terminals and self-service pumps at gas/petrol stations. These environments will typically have 8 to 32 (RS-232 or RS-485) ports by using multiple UARTs for communications.

Single and multi-channel UARTs are used in portable consumer applications such as multi-media products, Global Positioning System (“GPS”) and Personal Digital Assistant (“PDA”) devices. Products such as smart phones and PDAs utilize multiple serial interfaces to connect to Bluetooth, compact flash, IrDA, serial docking interface and GPS receivers for wireless or wired interface to global positioning systems. When a Bluetooth or GPS receiver is not integrated in the device, an external module can easily be connected via the UARTs interface in most applications. Our UARTs are well suited for battery-operated applications that require mobility such as handheld data entry devices, security alarm and point-of-sale terminals.

Transceiver interface products facilitate the transfer of digital signals between or within electronic systems and ensure reliable connectivity between networks, computers and the rapidly expanding mix of digital peripherals and consumer portable devices that connect to them. Our single protocol RS-232 and RS-485 transceivers comply with international standards in delivering multi-channel digital signals between two systems. Our proprietary multi-protocol 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.

As a leader of UART solutions, we offer a broad line of industry-proven product families. Our product portfolio consists of single, dual, quad and octal channel devices with enhanced feature sets and a broad range of packaging options. These products provide an easy migration path from one product generation to the next. These solutions are highly integrated UARTs that we believe are the defacto industry standard for UART with First-In First-Out (“FIFO”) used in multi-port applications. We introduced our first to market wireless UART solution in the fiscal year 2008. The wireless UART is a transmitter and receiver chipset which allows applications to send and receive data wirelessly over a secure proprietary protocol. The proprietary protocol enables the application to achieve the highest degree of security to protect the data. The wireless UART solution integrates the UART and radio frequency (“RF”) function into a simple to use small footprint solution. Coupled with our proprietary driver software, our customers have an easy turnkey wireless solution which eliminates the difficult software development activities they currently have.

Power Management

The power management market has changed considerably over time. The practice of considering power management at 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 becoming one of the primary problems to solve when defining a system. As a result, power solutions today are challenged to develop solutions which solve a variety of these problems.

Portable and consumer applications such as notebooks, set-top boxes and portable blood analyzers require a variety of power management and power display solutions. These applications are becoming more and more complicated as the dimensions continue to reduce, functions continue to grow, and longer battery life is required. The challenge to the power system is an increase in the number of voltages in the system and current required, while the space allowed decreases, operating voltages continue to drop, and higher efficiencies are required. We provide a portfolio of LED drivers, linear regulators and DC-DC regulators which are targeted for these applications. As a leader in charge pump backlight solutions, we were the first company to achieve 90% efficiency in the flash LED market with the fewest external components.

In the communications and industrial markets, power systems have also seen a significant trend toward multiple system voltages, increased currents, increased efficiency needs, and smaller spaces, but the challenge of higher input voltages has now been added. This additional challenge has caused the introduction of the intermediate bus architecture which is an additional regulation step for the power system prior to regulating to the final working voltages that the system application needs. This architecture requirement has reduced the overall system efficiency which then requires the system design to provide more raw energy to the system and also to dissipate a higher level of heat due to the inefficiencies of the system. Our high voltage controller and DC-DC regulator solutions are designed to eliminate the intermediate bus regulator and simplify the system design, while at the same time, reducing the system losses by as much as 50%.

As our progress deepens in power, our digital power efforts will become a solution which integrates the power management function within an application into a cohesive power system. The potential is beyond simple integration as our digital power solution which we have defined with specific OEM customers will enable our customers to achieve performance results that they were not able to achieve with traditional solutions.

8

Utilization of our devices accelerates time-to-market and system performance by reducing development time and addressing the growing need for board space savings, lower power and increased bandwidth requirements for communications, industrial and consumer applications. For example, our UARTs, Backlight Display Drivers, and regulators are well suited for battery-operated applications that require mobility such as handheld data entry devices, security alarms and point-of-sale terminals.

Storage

Market demand is driving the need for increased storage capacity for a host of consumer, home media and industrial applications where cost effective, dense storage is a requirement. There are many approaches to data storage deployment: Storage Area Network (“SAN”), Direct Attached Storage (“DAS”), Network Attached Storage (“NAS”), Redundant Array of Inexpensive Disks (“RAID”) and Just a Bunch of Disks (“JBOD”). Each of these will support unique configurations (number of disk drives) and locations (internal to the system, or connected externally to an enclosure). Connecting to all of these storage environments entails supporting industry-adopted protocols including Serial Advanced Technology Attachment (“SATA”) and Serial Attached SCSI (“SAS”), among others. The SATA I/II specifications were recently standardized as a serial interconnect technology of choice between advanced host controllers and storage drives. Our SATA port multipliers enable distribution of data across multiple disk drives from a single host. Our port selectors enable multiple hosts to access a single drive. These approaches ensure greater data reliability and security.

Strategy

We strive to be a leading provider of high performance, system-level mixed-signal solutions for a broad range of connectivity markets including telecom, industrial, storage and consumer. 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 strong analog and mixed-signal design expertise, we integrate mixed-signal physical interface devices for a broad range of interface solutions. In the communications infrastructure market, we offer products that integrate transceivers, power management, jitter attenuators and framers/ATM UNIs on a single IC. This enables our OEMs to use less board space and reduce their overall system cost.

Leverage Broad Product Portfolio to Accelerate Development of High Performance Connectivity Solutions.    We have developed a strong presence in the communications market, 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 communications products. We plan to expand this portfolio by developing integrated solutions that extend the reach of our offerings into new input/output applications.

Focus on Growing Market Share Within the Communications and Storage Markets.    We target communications markets, including T/E carrier, ATM, and SONET/SDH. In the storage market, we target Direct Attached Storage (DAS) and Network Attached Storage (NAS) applications. We have built substantial expertise in the areas of analog and digital design, systems architecture and applications support. We believe that the integration of these capabilities enables us to develop solutions addressing the high-bandwidth physical layer requirements of communications systems OEMs. Our broad product offerings support differentiated features that we believe will enable us to increase our market share. Additionally, we seek to expand our markets by incorporating adjacent functionality into our products.

Leverage Broad Product Portfolio in Serial Communications and Power Management to Increase Market Share in Industrial, Communications and Consumer Markets.    Aside from our comprehensive portfolio of 8-bit and PCI UART devices and DC-DC regulators, we provide higher value to our customers by integrating adjacent functionalities. These include UARTs integrated with RS-232 and RS-485 transceivers as well as power management integrated with communications. We also offer expanded low voltage, low power consumption devices in small form factors to accelerate our reach into high-volume consumer applications for increased market share.

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. In addition, we believe that collaborative relationships help us to obtain early design wins and to increase the likelihood of market acceptance of our new products.

Use Standard CMOS and 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.

Leverage 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 leveraging the fabless model, we can focus on our core competencies in sales and marketing as well as in product design, development and support.

10

Leverage our Channel Partners.    We have an extensive partnership with our distributors and representatives throughout the world representing a significant portion of our total revenue. Through our partners, we have access to large market segments which we cannot directly support. Our activities with our partners are to extend our expertise and product exposure by enabling our partners to create new demands for our solutions as well as aid us in defining our next generation solutions.

Expand our Business Through Acquisition.    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 technological 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 representatives and two independent, non-exclusive primary distributors, as well as our own direct sales organization.

All our manufacturing partners have been certified to ISO 9001:2000 and are automotive spec, TL16949 compliant or soon to be compliant.

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 complexity of integrated circuits 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 properties through licensing or purchases. We also augment our skill sets and intellectual properties through university collaborations, 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 successes. While we continually upgrade our internal technology to develop innovative products, as a fabless company, we continue to seek or work with foundries to procure our wafer manufacturing processes. We spent $30.7 million, $25.8 million and $24.7 million on research and development in fiscal years 2008, 2007 and 2006, respectively. For the explanation of increased expense in R&D, 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 integrated circuits is generally characterized by longer product life cycles and less dramatic price reductions than the market for digital integrated circuits, we face substantial competition in each market in which we participate.

We believe that the principal competitive factors for our related semiconductor industry are:

• time-to-market;

• product quality and reliability;

• customer support and services;

• price;

• total system cost;

12

• product features;

• new product innovation; and

• compliance with industry standards.

While, we compete favorably with respect to each of these factors, many of our current and potential competitors may have certain advantages over us, for example:

• longer presence in key markets;

• greater name recognition;

• stronger financial position and liquidity;

• more secure supply chain;

• access to larger customer bases; 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 storage include Silicon Image, Inc. and Marvell Technology Group Ltd. Competitors in serial interface include NXP B.V. (formerly a division of Royal Philips Electronics), Texas Instruments Incorporated, Analog Devices, Inc., Intersil Corporation, Linear Technology Corporation and Maxim Integrated Products, Inc. Our primary competitors in power 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.

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 at all. 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

We believe that our intellectual property is critical to our current and future success. However, we do not believe that it is materially dependent upon any one patent. 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 179 patents issued and 43 patent applications pending in the United States. We have 38 patents issued and 101 patent applications pending in various foreign countries. Our existing patents will expire between 2009 and 2025, 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.

We, however, 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

13

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 and Latin America, may not protect our products and intellectual property rights to the same extent as the laws of the United States of America.

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

• stop selling, incorporating or using our products that use the infringed intellectual property;

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

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

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

Employees

As of March 30, 2008, we employed 404 full-time employees, with 115 in research and development, 104 in operations, 120 in marketing and sales and 65 in administration. Of the 404 employees, 87 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. We believe our employee relations are good.

ITEM 1A. RISK FACTORS

If we are unable to integrate, operate and manage the combined company resulting from our merger with Sipex, we may fail to realize the expected benefits of the merger, which may adversely affect our financial results.

Our merger with Sipex in August 2007 resulted in the combination of two previously independent public companies. Although we have achieved and expect to achieve additional benefits as a result of the merger, we may still face significant challenges to realize all expected benefits and synergies of the merger and there can be no assurance that we will realize all of the anticipated benefits. The integration of the companies has been and is a complex, time-consuming and expensive process that can and may disrupt our business and divert our management’s focus and resources from the day-to-day operation of the business. Integration challenges include, but are not limited to:

• integrating the management teams, strategies, cultures and operations of the two companies;

• retaining and assimilating the key personnel of each company;

16

• integrating sales, engineering, operations, marketing, information technology and business management;

• retaining and maintaining relationships with existing customers, distributors and other partners of each company;

• achieving expected enterprise synergies of the merger as rapidly as anticipated by us or financial or industry analysts;

• integrating and managing multiple geographic locations;

• integrating purchasing and procurement and retaining the main sources of supply and/or services of both companies;

• integrating the business process and related information technology applications and infrastructure of the two companies;

• developing new products and services that optimize the assets and resources of both companies;

• coordinating research and development activities to enhance the timely development of new products and technologies; and

• creating uniform standards, controls (including internal control over financial reporting), procedures, policies and information systems.

Meeting these challenges has involved and will continue to involve considerable risks, such as:

• the potential disruption of each company’s ongoing business and distraction of management;

• the difficulty of fully leveraging acquired technology and intellectual property rights into our products;

• potential unknown liabilities associated with the merger;

• unanticipated expenses related to integration, including technical and operational integration; and

• the impairment of relationships with employees, customers and channel partners such as Future, including potential changes in existing agreements or delay or deferral in decisions, as a result of the integration process.

Combining businesses and operations of this magnitude and scope is challenging. We may not ultimately succeed in integrating Sipex’s business into ours and we may not realize all the anticipated benefits of the merger. If we do not succeed in addressing these challenges or any other problems encountered in connection with the merger, our operating results and financial condition could be adversely affected.

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:

• loss of or changes to key executives;

• our anticipated or actual operating results;

• announcements or introductions of new products by us or our competitors;

• technological innovations by us or our competitors;

• 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;

17

• 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 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 harming our business, results of operations and financial condition.

In addition, at times the stock market has experienced and is currently experiencing extreme price and volume fluctuations that affect the market prices 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 financial results may fluctuate significantly because of a number of factors, many of which are beyond our control.

Our financial results may fluctuate significantly. Some of the factors that affect our financial results, many of which are difficult or impossible to control or predict, are:

• the cyclical nature of the semiconductor industry;

• our 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 that has various margins;

• the effect of the timing of sales by our resellers on our reported results as a result of our sell-through revenue recognition policies;

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

• management of customer, subcontractor and/or channel inventory;

• delays in shipments from our subcontractors causing supply shortages;

• inability of our subcontractors to provide quality products timely;

• dependency on a single product with a single customer and/or distributors;

• 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; and

• disruption in sales or distribution channels;

18

• our ability to maintain and expand distributor relationships;

• changes in sales and implementation cycles for our products;

• the ability of our suppliers and customers to obtain financing or to fund capital expenditures;

• risks associated with entering new markets;

• the announcement or introduction of products by our existing competitors or potential 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;

• erosion of average selling prices coupled with the inability to sell newer products with higher average selling prices, resulting in lower overall revenue and margins;

• delays in product design life cycles;

• 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 suppliers;

• disruptions in our or our customers’ supply chain due to natural disasters, fire, outbreak of communicable diseases, labor disputes, civil unrest or other reason;

• delays in successful transfer of manufacturing process 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;

• 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;

• increase in manufacturing costs;

• higher mask tooling costs associated with advanced technologies;

• the amount and timing of our investment in research and development;

• costs and business disruptions associated with stockholder or regulatory issues;

• 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 loss;

• increased costs and time associated with compliance with new accounting rules or new regulatory requirements;

19

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

• 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

• changes 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 future 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, operating results are likely to be materially adversely affected.

Because a significant portion of our total assets are 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 adversely impact our financial condition and results of operations.

We accounted for our merger with Sipex using the purchase method of accounting. A portion of the purchase price for this business is allocated to identifiable tangible and intangible assets and assumed liabilities based on estimated fair values at the date of consummation. The excess purchase price was allocated to goodwill. In accordance with the SFAS 142, Goodwill and Other Intangible Assets, goodwill is not amortized but is reviewed annually or more frequently if impairment indicators arise, for impairment. We conduct our annual analysis of our goodwill in the fourth quarter of our fiscal year. Intangible assets that are subject to amortization are reviewed for impairment in accordance with FAS 144, Accounting for the Impairment or Disposal of Long-Lived Assets, whenever events or changes in circumstances indicate that its carrying amount may not be recoverable.

In the fourth quarter of 2008, we conducted our annual impairment analysis of our goodwill and an impairment analysis of our long-lived assets, as our market capitalization was below its net book value for an extended period of time. We concluded that our carrying value of our goodwill and other intangible assets acquired in the Sipex merger exceeded the implied fair value of these assets. As a result, we recorded an impairment charge of $165.2 million. There can be no assurance that when we perform future impairment tests, the carrying value of goodwill and other intangible assets would not exceed the implied fair value and therefore additional adjustments may be required. Such adjustment would result in a charge to operating income in that period.

A significant portion of our total assets are represented by goodwill and other intangible assets, which, in accordance with FAS 142, require an annual impairment review. Unlike other assets, goodwill cannot be defined as a stand-alone asset and must be valued as a residual of all other assets. The assessment of goodwill 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 have adverse impact on our operating results and our effective tax rate.

We have incurred additional costs associated with the Sipex merger and may continue to incur costs relating to the merger going forward.

We have incurred additional costs associated with the merger. We may incur additional charges to operations in the quarters following the consummation of the merger associated with the integration. We anticipate that the combination of the two companies will continue to require future cash outflows for assumed Sipex liabilities and integration costs. If the benefits of the merger do not exceed the integration costs, our financial results may be adversely impacted.

20

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 undertaken a number of strategic acquisitions and investments in the past, including our recent merger with Sipex, and may do so 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;

• 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.

Additional risks involved with acquisitions include:

• difficulties in integrating the operations, technologies, products and personnel of the acquired company or its assets;

• difficulties in supporting acquired products or technologies;

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

• failure to retain key personnel;

• failure to retain customers and/or customer programs;

• unexpected capital equipment outlays and related expenses;

• 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 balance;

• 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.

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.

21

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

We are experiencing, and may continue to experience, unforeseen complications from the transfer of manufacturing processes to Hangzhou Silan Microelectronics Co. Ltd. and Hangzhou Silan Integrated Circuit Co. Ltd. (collectively “Silan”) in China and Episil Technologies Inc. (“Episil”) in Taiwan.

Sipex transferred its manufacturing processes to foundries operated by Silan and Episil in conjunction with the closure of its Milpitas, California wafer fabrication facility. The transfer has been and continues to be a complicated and time-consuming process that has been met with significant unforeseen complications which has delayed the transfer and is requiring additional allocation of our resources. Additional unforeseen transferring or quality issues may arise in the future that could cause additional delays which could materially adversely impact our ability to timely produce our products to meet customer demand. In addition, the parties may be unable to achieve all or any of the expected benefits of the relationship within the anticipated time-frames. The anticipated synergies between us and Silan or Episil may not be as significant as originally expected. The manufacturing processes and wafer testing for certain products may not be qualified by us following the transfer from us to Silan or Episil, or the qualification process may take significantly longer than expected. This could result in additional operating costs, loss of customers and business disruptions.

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, 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 adversely affect our 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 financial condition and results of operations.

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 technologies;

• evolving and competing industry standards;

• changing customer requirements;

• increasing price pressure;

• increasing product development costs;

• long design-to-production cycles;

• competitive solutions;

22

• 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);

• finite market windows for product introductions; and

• short end market product life cycles.

Our growth depends in part on our successful 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.

Products for our customers’ applications are based on 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.

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 have secured a significant number of 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 and consolidations 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.

23

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 adversely impact our financial position.

The general state of the U.S. and global economies, as well as our market, may materially and adversely impact our business, financial condition and results of operations.

Periodic declines or fluctuations in the U.S. Dollar, corporate profits, 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. Our revenue and profitability have generally followed market fluctuations in our industry, which fluctuations have affected the demand for our own and our customers’ products, thus affecting our revenues and profitability. Our customers continue to experience consolidation in their industries which may result in project delays or cancellations. We are unable to predict the strength or duration of current market conditions or effects of consolidation. Uncertainties in anticipated spending levels or further consolidation may adversely affect 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 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 and continued price erosion. Our competitors include many large domestic and foreign companies that have substantially greater financial, technical and management resources and leverage than we have.

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 Silan to market our commodity interface products that could reduce our sales in the future. Loss of competitive position could result in price reductions, fewer customer orders, reduced revenues, reduced gross margins and loss of market share,

24

any of which would affect our operating results and financial condition. To remain competitive, we continue to evaluate our manufacturing operations, looking for additional cost savings and technological improvements. If we are unable to successfully implement new process technologies and to achieve volume production of new products at acceptable yields, our operating results and financial condition may be 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 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; and

• meet changing customer requirements.

There can be no assurance that our design, development and introduction schedules for new products or enhancements to our existing and future products will be met. In addition, there can be no assurance that these products or enhancements will achieve market acceptance, or that we will be able to sell these products at prices that are favorable.

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 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 adversely impacted.

25

We derive a substantial portion of our revenues from our two primary distributors, Future, a related party, and 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 Future and Nu Horizons as distributors, or a significant reduction in orders from them would materially and adversely affect our operating results, business and financial condition.

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.

Affiliates of Future, Alonim Investments Inc. and its two affiliates (collectively “Alonim”), own approximately 18% of our common stock, and as such, Alonim is our largest stockholder. This ownership position will allow Future to significantly influence matters requiring stockholders’ approval. Future’s ownership will continue to increase as a percentage of our outstanding stocks if we continue to repurchase our common stock. In addition, an executive officer of Future is on our board of directors, which could lead to actual or imputed influence from Future.

As a result of our merger with Sipex, 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, although Future is bound by a Lock-Up and Standstill Agreement until August 25, 2009, prohibiting Future from either soliciting proxies or seeking to advise anyone with respect to voting our stock. 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, although, by the terms of the same Lock-Up and Standstill Agreement, Future is prohibited from making any public announcements with respect to, or proposing, any extraordinary transaction involving us until the first anniversary of the merger date.

This relationship could also result in actual or imputed 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 foundries to manufacture our products. Any disruption in or loss of the foundries’ capacity to manufacture our products subjects us to a number of risks, which include 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), Bipolar processes and Bipolar-CMOS (BiCMOS) process. Chartered Semiconductor Manufacturing Ltd., or Chartered,

26

located in Singapore, manufactures the majority of the CMOS wafers from which our communications and UART products are produced. Episil, located in Taiwan, and Silan, located in China, manufacture the majority of 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. 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.

The manufacturing processes for our products are highly complex and are continuously being modified in an effort to improve yields and product performance. 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. In addition, yields can be adversely affected by minute impurities in the environment or other problems that occur in the complex manufacturing process. Many of these problems are difficult to diagnose and are time-consuming or expensive to remedy. In particular, 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. This risk is particularly significant in the near term as we have recently transferred certain of our manufacturing processes to Silan and Episil.

We do not have long-term wafer supply agreements with Chartered 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 Chartered and our other 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 conditions and operating results.

In addition, we cannot be certain that we will 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:

• 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;

• limited manufacturing capacity of the foundries; and

• potential misappropriation of our intellectual property.

We could experience a substantial delay or interruption in the shipment of our products or an increase in our costs due to any of the following:

• a manufacturing disruption experienced by foundries utilized by us 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 of management or consolidation by one of our foundries;

27

• extended time required to identify, qualify and transfer to alternative manufacturing sources for existing or new products;

• failure of our foundries to obtain raw materials and equipment;

• financial and operating stability of the foundries or any of their suppliers;

• acts of terrorism or civil unrest or an unanticipated disruption due to communicable diseases, political instability or natural disasters;

• a sudden, sharp increase in demand for semiconductor devices, which could strain the foundries’ manufacturing resources and cause delays in manufacturing and shipment of our products; and

• manufacturing quality control or process control issues.

To secure foundry capacity, we may be required to enter into financial and other arrangements with foundries, which could result in the dilution of our earnings or otherwise harm our operating results.

Allocation of a foundry’s manufacturing capacity may be influenced by a foundry customer’s size, the existence of a long-term agreement with the foundry or other commitments. To address foundry capacity constraints, we and other semiconductor companies that rely on third-party foundries have utilized various arrangements, including equity investments in or loans to foundries in exchange for guaranteed production capacity, joint ventures to own and operate foundries or “take or pay” contracts that commit a company to purchase specified quantities of wafers over extended periods. These arrangements may not be available to us on acceptable terms, if at all. Any of these arrangements could require us to commit substantial capital and, accordingly, could require us to reduce our cash holdings, incur additional debt or secure equity financing. This could result in the dilution of our earnings or the ownership of our stockholders or otherwise harm our operating results. Furthermore, we may not be able to obtain sufficient foundry capacity in the future pursuant to such arrangements.

If our foundries discontinue or limit the availability of the manufacturing processes needed to meet our demands or are unable to provide the technologies needed to manufacture our products, we may face production delays or be forced to terminate affected products, which could materially and adversely impact our business, financial condition and results of operations.

Our wafer requirements represent a small portion of the total production of the foundries that manufacture our products. As a result, we are subject to the risk that a foundry may cease production of a wafer fabrication process required by us. Additionally, we cannot be certain that our foundries will continue to devote resources to the production of our products or continue to advance the process design technologies on which the manufacturing of our products are based. Each of these events could increase our costs and harm our ability to deliver our products on time, or force us to terminate affected products, thereby materially and adversely affecting our business, financial condition and results of operations.

Our dependence on third-party subcontractors to assemble and test our products subjects us to a number of risks, including the potential for an inadequate supply of products and higher materials costs. These risks may lead to delayed product delivery or increased costs, which could materially and adversely affect our business, financial condition and results of operations.

We depend on independent subcontractors in Asia for all of the assembly and the majority of the testing and shipping of our products to end customers. Our reliance on these subcontractors involves the following risks:

• our reduced control over manufacturing yields, production schedules and product quality;

• the potential closure, change of ownership, change in business conditions or relationships, change of management or consolidation by one or more of our subcontractors;

• possible unavailability of qualified assembly or test services;

28

• the subcontractors may cease production on a specific package type used to assemble product required by us and the possible inability to obtain an alternate source to supply the package;

• potential increases in assembly and test costs;

• long-term financial stability of our subcontractors and their ability to invest in new capabilities and/or expand capacity to meet increasing demand;

• disruption of services due to the outbreak of communicable diseases, acts of terrorism, natural disasters, labor disputes or civil unrest;

• disruption of manufacturing or test services due to relocation of subcontractor manufacturing facilities;

• subcontractors imposing higher minimum order quantities for substrates;

• failure of our subcontractors to obtain raw materials and equipment;

• increasing cost of raw materials resulting in higher package costs;

• entry into “take-or-pay” agreements;

• additional costs to qualify new local assembly subcontractors for prototypes;

• difficulties in selecting, qualifying and integrating new subcontractors;

• reallocation or limited manufacturing capacity of the subcontractors;

• a sudden, sharp increase in demand for semiconductor devices, which could strain our subcontractor’s manufacturing resources and cause delays in manufacturing and shipment of our products;

• limited warranties from our subcontractors for products assembled and tested for us; and

• third-party subcontractors’ abilities to transition to smaller package types and to new package compositions.

These risks may lead to shipment delays and supply constraints of our products or increased cost for the finished products, either of which could adversely affect our business, financial condition or results of operations.

Our ability to meet current demand or any increase in demand for our products may be limited by our ability to test our semiconductor wafers.

As part of our manufacturing process, we must test many of our semiconductor wafers using certain “probe testing” equipment. As such, our ability to meet current demand or any increase in demand for our products depends, in part, on our ability to purchase and install sufficient testing equipment. Obtaining and installing this equipment is a time and capital intensive process and depends on our ability to accurately predict future sales. If we are unable to estimate future sales correctly or we are unable to obtain the necessary testing equipment on a timely basis, we may be unable to meet the current demand or any increased demand for our products.

Our reliance on foreign suppliers exposes us to risks associated with international operations, any of which could materially and adversely impact our business, financial condition and results of operations.

We use semiconductor wafer foundries and assembly and test subcontractors throughout Asia to manufacture a significant portion of our products. Our dependence on these subcontractors involves the following risks:

• disruption of services due to political, civil, labor and economic instability;

• disruption of services due to natural disasters or outbreak of communicable diseases;

• disruption of transportation to and from Asia;

29

• 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.

These risks may lead to delays in product delivery or increased costs, either of which could harm our profitability and customer relationships, thereby materially and adversely impacting 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, incentivize and retain other qualified personnel.

The success of the merger will depend in part on the retention of personnel critical to the business and operations of the combined company due to, for example, their technical skills or management expertise. Current and prospective employees may experience uncertainty about their future roles with us. In addition, competitors may recruit employees during our integration, as is common in high technology mergers. If we are unable to retain personnel that are critical to successful integration and 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.

In the future, we may not be able to attract and retain qualified personnel, including executive officers and other key management and technical personnel necessary for the management of our business. 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. 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 past 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. Our employees are employed at-will, which means that they can terminate their employment at any time. The failure to retain and recruit, as necessary, key design engineers, technical, sales, marketing and executive personnel could harm our business, financial condition and results of operations.

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 significantly impact our results of operations. Our change in the revenue recognition used for sales to our two primary distributors from sell-in to sell-through basis has impacted our financial results as revenues and costs which had been recognized upon sell-in to these distributors are now deferred until these two distributors sell-through to their customers. The delay in revenue recognition has unfavorably affected our current period operating results.

30

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 mergers;

• changes in available tax credits;

• changes in share-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 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 acquired significant net operating loss (“NOL”) carryforwards as a result of the Sipex merger. The utilization of acquired NOL carryforwards is subject to IRS’s complex limitation rules that carry significant burdens of proof. The eventual ability to utilize our estimated NOL carryforwards is subject to IRS scrutiny and our future results may not benefit as a result of potential unfavorable IRS rulings.

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

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

• 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;

31

• limited intellectual property protection;

• foreign currency exchange fluctuations;

• the burden of complying with foreign laws and treaties; 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 circuits 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 present for an extended period of time.

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. We may not be able to meet our expected revenue levels or results of operations if there is a reduction in our order backlog during any particular period and we are unable to replace those sales during the same period.

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.

32

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, it may not be commercially feasible to enforce. Moreover, we cannot be certain that our competitors will not 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 substantial 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 were 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.

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 that is in excess of the 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 also increased our 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.

33

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 of our products and harm our business.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 2. PROPERTIES

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

We also lease smaller facilities in Belgium, Canada, China, 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.

Dividend Policy

We have never declared or paid any cash dividends on our capital stock and we do not currently intend to pay any cash dividends on our common stock. We expect to retain future earnings, if any, to fund the development and growth of our business. Any future determination to pay dividends on our common stock will be, subject to applicable law, at the discretion of our board of directors and will depend upon, among other factors, our results of operations, financial condition, capital requirements and contractual restrictions.

Securities Authorized for Issuance under Equity Compensation Plans

Information regarding the securities authorized for issuance under our equity compensation plans can be found under Part III, Item 12 of this Annual Report on Form 10-K and is incorporated herein by reference.

Issuer Purchases of Equity Securities

From time to time, we acquire outstanding common stock in the open market to partially offset dilution from our stock awards program, to increase our return on our invested capital and to bring our cash to a more appropriate level for our company. At March 30, 2008, approximately $25.3 million remained available under our previously announced program. We may continue to utilize the stock purchase program, which would reduce our cash, cash equivalents and/or short-term investments available to fund future operations and to meet other liquidity requirements.

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, develops, markets and sells connectivity and power management products to the consumer, communications and industrial markets. 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 system and industrial automation equipment. Our portfolio spans a wide range of performance solutions from direct current to direct current (“DC-DC”) regulators and controllers, voltage references, microprocessor supervisors, charge pump regulators and light-emitting diode (“LED”) drivers, single and multi-channel Universal Asynchronous Receiver/Transmitter (“UART”) for portable and wireless applications, serial interface, port multipliers for storage applications, to T/E (T: North America and Asia transmission interface; E: European transmission interface) and Synchronous Optical Network/Synchronous Data Hierarchy (“Sonet/SDH”) communications. The solutions are designed working directly with large original equipment manufacturer (“OEM”) customers who help drive our technology roadmap and system solutions.

We market our products worldwide with sales offices and personnel located throughout the Americas, Europe, Asia and Japan. Our products are sold in the United States through a number of manufacturers’ representatives and distributors. Internationally, our products are sold through various regional and country specific distributors with locations 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 consist primarily of sales that are denominated in U.S. Dollars. Such 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.”

In December 2007, we changed our fiscal year end from March 31 to a 52-53 week fiscal year ending on the Sunday closest to March 31. As part of this change, each fiscal quarter will also end on the Sunday closest to the end of the corresponding calendar quarter. The third fiscal quarter of 2008 included 91 days from October 1, 2007 to December 30, 2007. The fourth fiscal quarter of 2008 included 91 days from December 31, 2007 to March 30, 2008. Hereinafter, the fiscal years ended March 30, 2008, March 31, 2007 and March 31, 2006 are also referred to as “2008,” “2007” and “2006” unless otherwise indicated.

In August 2007, we completed our merger with Sipex Corporation (“Sipex”), a company that designed, manufactured and marketed high performance, analog integrated circuits (“IC”) used by OEMs in the computing, consumer electronics, communications and networking infrastructure markets. As a result of the merger, we have combined product offerings, increased technical expertise, distribution channels, customer base and geographic reach as well as reduced expenses due to significant cost synergies.

39

Prior to our merger with Sipex in August 2007, the functional currency of each of our foreign subsidiaries was the local currency of that country. 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 adjustment of our subsidiaries prior to changing our functional currency was immaterial.

The accounts of foreign subsidiaries have been remeasured into U.S. Dollars in accordance with the Financial Accounting Standards Board (“FASB”) Statement of Financial Accounting Standards No. 52, Foreign Currency Translation (“FAS 52”). Accordingly, foreign currency is remeasured to U.S. Dollars for financial 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 the “Interest income and other, net” line item 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.

EXECUTIVE SUMMARY

During fiscal year 2008, we continued to execute on our strategy of growing the company through new product introductions and through acquisitions.

We acquired Sipex in August 2007 for 16.5 million shares of our common stock plus the assumption of stock options to purchase approximately 2.2 million shares of our common stock and the assumption of warrants to purchase approximately 280,000 shares of our common stock.

Subsequent to the merger, we grew our geographic reach into the high growth Asia marketplace and benefited from stronger distributor relationships. We made significant progress to integrate the organization and information systems and rationalize our sales channels, development projects, business processes, compensation plans and internal controls. We believe approximately 75% of our integration has been achieved. Through the success of our rationalization of business processes and efforts to update our internal controls, we are able to assess the effectiveness of our internal control over financial reporting for the combined company for fiscal year 2008.

We expect the benefit from our synergy savings to increase in the first fiscal quarter of 2009 and expect to see an increase in revenue through improved access to channel partners and cross-selling new products in future quarters.

We purchased Fyrestorm Inc.’s (“Fyrestorm”) intellectual property from its secured creditors for $3.2 million in cash in February 2008. The purchased intellectual property gave us the rights to thirty patents related to digital predictive algorithms. Fyrestorm was a private, venture-funded company that developed an all-digital adaptive loop control technology designed to enable efficient and extremely fast response switching-mode power supplies.

Our net sales for fiscal year 2008 were $89.7 million, an increase of $21.2 million or 31% as compared to net sales for fiscal year 2007. The increase was primarily due to net sales of $28.1 million associated with Sipex products acquired in August 2007. The transition of the recognition of revenue through our two primary distributors from the sell-in to the sell-through method reduced net sales by an estimated $6.9 million.

For fiscal year 2008, sales of our communications products represented 31% of our net sales, as compared to 42% in each of the fiscal years ended March 31, 2007 and 2006, respectively. For fiscal year 2008, sales of our interface products represented 56% of our net sales, as compared to 58% in each of the fiscal years ended March 31, 2007 and 2006, respectively. For fiscal year 2008, sales of our power management products, a new line of products which we acquired from Sipex, represented 13% of our net sales.

40

Gross profit as a percentage of net sales in fiscal year 2008 was 45% as compared to 68% for both fiscal years 2007 and 2006, respectively. The reduction in gross margin was a result of lower gross margins on acquired Sipex products, the amortization of the fair value adjustment for inventories (2%) and the amortization of intangible assets (5%) associated with the Sipex merger.

Our operating expenses for fiscal year 2008 were $242.6 million, or $191.8 million higher than fiscal year 2007, and included a non-cash charge of $165.2 million for the impairment of goodwill and other intangible assets, an in-process research and development charge of $8.8 million, an amortization of intangible assets of $6.4 million and a $2.4 million of other expenses of related to the Sipex merger.

For fiscal year 2008, our operating loss was $202.4 million. Interest income and other, net was $16.0 million and interest expense was $0.8 million. We also recorded an impairment charge of $0.6 million associated with our non-marketable securities during the period. The net loss for fiscal year 2008 was $195.9 million, or $4.55 loss per share.

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 (6) long-lived assets; 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, see Part 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 upon turn out to be inaccurate.

Revenue Recognition

We recognize revenue in accordance with the SEC Staff Accounting Bulletin 104, Revenue Recognition (“SAB 104”). SAB 104 requires that four basic criteria must be met before revenue can be recognized: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services 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 the fiscal years ended March 30, 2008, March 31, 2007 and March 31, 2006, approximately 35%, 38% and 39%, 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%, 62% and 61%, respectively, of our net sales were derived from sales to other distributors, OEM customers and other non-distributors.

41

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, title has transferred, 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:

Our two primary distributors’ agreements 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 to each of our distributors using either of the methodologies in the following table. Once adopted, the revenue methodology for a distributor will be maintained unless there is a change in circumstances indicating the methodology 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 returns, pricing allowance 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 is 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 revenues, gross margin, deferred income and allowances on sales to distributors and net income.

Our historical patterns of returns, pricing allowances and other concessions with distributors have been fairly consistent, which has enabled us to reasonably estimate such allowances at the time of shipment. Therefore, we have historically recognized revenue on sales to all distributors on a 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 merger with 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 merger, Sipex recognized revenue on sales to all distributors on a sell-through basis. Consistent with Sipex’s past practice, we have concluded that we are not able to reasonably estimate such allowances at the time of shipment of products to Sipex’s distributors. Therefore, we have determined that consistent with Sipex’s past practice, we

42

will continue to recognize sales to Sipex’s distributors on a sell-through basis. In addition, as a result of the merger, our relationships, marketing and sales practices with our two primary distributors have changed. Further, as disclosed Part II, Item 8 – “Financial Statements and Supplementary Data” and “Notes to Consolidated Financial Statements, Note 5—Related Party Transaction,” Future is now 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, as of August 26, 2007, we determined it was appropriate that revenue on all sales to Future and Nu Horizons be recognized on a sell-through basis.

Inventories

Our policy is to establish a provision for excess inventories, based on the nature of the specific product that is greater than six or 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. Our net inventories at March 30, 2008 were $14.2 million, compared with $4.8 million at March 31, 2007. The increase was primarily due to the inventory acquired in connection with the Sipex merger. 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 account for income taxes under the provisions of Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes (“FAS 109”). Under this method, 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 17—Income Taxes” for more details about our deferred tax assets and liabilities.

We acquired significant net operating loss (“NOL”) and tax credit carryforwards as a result of the Sipex merger. The utilization of these NOL and tax credit carryforwards are 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. Our application of these complex rules is subject to examination by the IRS and state taxing authorities. An unfavorable outcome could further restrict our ability to utilize the acquired NOL and tax credit carryovers prior to their expiration.

We must determine the probability that we will be able to utilize our deferred tax assets. If we determine that recovery is unlikely, then a valuation allowance against our deferred tax assets must be recorded by increasing our income tax expense. As of March 30, 2008, our net deferred tax assets recorded on our consolidated balance sheet is zero.

43

Uncertain Income Tax Provisions

Effective April 1, 2007, we adopted Financial Accounting Standards Interpretation No. 48, Accounting for Uncertainty in Income Taxes – an interpretation of FASB Statement No. 109 (“FIN 48”). FIN 48 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.

The cumulative effect of adopting FIN 48 was a decrease in the liability for uncertain tax positions and an increase of $0.2 million to the April 1, 2007 opening retained earnings balance. Upon adoption of FIN 48, the liability for uncertain tax positions at April 1, 2007 was $0.8 million. Consistent with the provisions of FIN 48, we reclassified $0.8 million of income tax liabilities from current to non-current liabilities because payment of cash is not anticipated within one year of the balance sheet date. In addition, we decreased current taxes payable and deferred tax assets by $3.5 million for unrecognized tax benefits which serve to reduce net operating loss and tax credit carryforwards.

The total amount of gross unrecognized tax benefits as of the April 1, 2007 adoption date of FIN 48 was $7.7 million. The unrecognized tax benefits increased by $1.7 million during the fiscal year ended March 30, 2008 to $9.4 million. If recognized, all of these unrecognized tax benefits would be recorded as a reduction of future income tax provision before consideration of any changes in valuation allowance.

Stock-Based Compensation

On April 1, 2006, we adopted Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment (“FAS 123R”) by using the modified prospective transition method. In accordance with the modified prospective transition method, we began recognizing compensation expense for all share-based awards granted on or after April 1, 2006, plus unvested awards granted prior to April 1, 2006. Under this method of implementation, no restatement of prior periods has been made. The cumulative effect of adopting FAS 123R was not significant.

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 12—Stock-Based Compensation” for more details about our assumptions used in calculating the stock-based compensation expenses and activities of our stock-based compensation.

On March 22, 2006, our board of directors approved the full acceleration of vesting of all employee stock options, including options held by our executive officers, with exercise prices in excess of $15.05. Such vesting acceleration did not apply to any options held by our non-employee directors. As a result of the decision to fully accelerate the vesting of stock options, as described above, options to purchase approximately 1.1 million shares of our common stock became fully vested and immediately exercisable effective as of March 22, 2006.

Because the accelerated options’ exercise prices were in excess of the market value of our common stock at the time of the acceleration, we believe that the incentive value to our employees of the associated unvested options was minimal. The acceleration eliminated future compensation expense we would otherwise have had to recognize in our statements of operations with respect to these options under FAS 123R. As a result of this

44

action, approximately $4.9 million of stock-based compensation expense, net of taxes, will be excluded from stock-based compensation for periods subsequent to fiscal year 2006.

In fiscal year 2007, our stockholders ratified Exar Corporation 2006 Equity Incentive Plan (the “2006 Plan”). Within the terms of the 2006 plan, we now grant stock options, restricted stock units (“RSUs) and performance-based awards. At March 30, 2008, unrecognized stock-based compensation was $5.0 million and $2.5 million for stock-options and RSUs, respectively, with remaining weighted average recognition periods of 2.64 year and 1.41 years, respectively.

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 follow the provisions of Statement of Financial Accounting Standards No. 142, Goodwill and Other Intangible Assets (“FAS 142”), under which goodwill is no longer subject to amortization. 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 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, if any. Because we have one reporting unit under FAS 142, we utilized an entity-wide approach to assess goodwill for impairment. We performed our annual goodwill impairment analysis during the fourth fiscal quarter of 2008 pursuant to the steps and requirements under FAS 142 and recorded a $128.5 million impairment loss which was included in the “Goodwill and other intangible asset impairment” line item in the consolidated statements of operations. See Part II, Item 8 – “Financial Statements and Supplementary Data” and “Notes to Consolidated Financial Statements, Note 8—Goodwill and Intangible Assets” for more details about our goodwill.

Long-Lived Assets

Our long-lived assets include land, buildings, equipment, furniture and fixtures, privately held equity investments 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 evaluate the recoverability of our long-lived assets in accordance with Statement of Financial Accounting Standards No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets (“FAS 144”). 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 the fourth fiscal quarter of 2008, we concluded that our market capitalization was below our net book value for an extended period of time and, as a result, long-lived assets were tested for recoverability. We determined that the carrying value of intangible assets acquired in the Sipex merger exceeded the fair value. We used the income approach to determine the fair value of these intangible assets. The evaluation resulted in an impairment charge of $36.7 million against intangible assets which was included in the “Goodwill and other intangible asset impairment” line item in the consolidated statements of operations. Substantially all of our property, plant and equipment and other long-lived assets are located in the United States.

RESULTS OF OPERATIONS

Net Sales by Product Line

As described above in Critical Accounting Policies and Estimates, we began to recognize revenue on shipments to our two primary distributors on a sell-through basis beginning August 26, 2007.

Certain net sales by product line for prior years have been reclassified to be consistent with the presentation of the fiscal year of 2008.

45

The following table shows net sales by product line in absolute dollars and as a percentage of net sales for the periods indicated (in thousands):

	March 30, 2008				March 31, 2007				March 31, 2006				2008 vs. 2007 Change		2007 vs. 2006 Change

Fiscal Year 2008 versus Fiscal Year 2007

Communications

Communications products include network access and transmission products and storage products as well as optical products acquired in the Sipex merger.

Net sales of communications products for fiscal year 2008 included $1.6 million of additional sales from the merger. We estimate the change of revenue recognition to a sell-through basis at our two primary distributors reduced the communication product sales by $1.7 million for the fiscal year of 2008.

Net of these effects, net sales of network access and transmission products for the fiscal year of 2008 were $0.4 million lower as compared to the fiscal year of 2007, primarily due to price erosion on a limited number of T/E carrier products and reduced sales from last time buy orders partially offset by increased volumes of T/E carrier and acquired SONET product sales.

Interface

Interface products include UARTs, video, imaging and other products as well as transceiver products acquired in the Sipex merger.

Net sales of interface products for the fiscal year of 2008 included $14.6 million of additional sales relating to sales of products acquired in the Sipex merger. We estimate the change of revenue recognition to a sell-through basis at our primary distributors reduced the UART product sales by $5.3 million for the fiscal year of 2008.

Net of these effects, net sales of interface products for the fiscal year of 2008 were $0.6 million higher as compared to the fiscal year of 2007, primarily due to increased volume of UART sales partially offset by a shift in mix to lower priced UARTs, price erosion on a limited number of UART products and reduced sales from last time buy orders.

Power Management

Power management products, including DC-DC regulators and LED drivers, were acquired in the Sipex merger and increased net sales for the fiscal year of 2008 by $11.9 million.

Fiscal Year 2007 versus Fiscal Year 2006

Communications

Net sales of network access and transmission products for fiscal year 2007 increased $2.6 million, or 11%, as compared to net sales in fiscal year 2006. T/E carrier product sales grew 7% year over year, primarily due to increased sales volume attributable to growth in end customer demand. SONET products sales grew 27% year over year due to increased sales volume of the acquired SONET products partially offset by price erosion on a limited number of products.

46

In addition, net sales from last time buy orders for other communications products for fiscal year 2007 were $2.1 million lower as compared to fiscal year 2006.

Interface

Net sales of UART products for fiscal year 2007 increased $2.0 million as compared to net sales in fiscal year 2006, primarily attributable to increased sales volume partially offset by price erosion on a limited number of products.

Video, imaging and other net sales for fiscal year 2007 decreased by $1.1 million as compared to fiscal year 2006, primarily due to reduced shipments to Hewlett Packard and another customer.

Net Sales by Channel

The following table shows net sales by channel in absolute dollars and as a percentage of net sales for the periods indicated (in thousands):

	March 30, 2008				March 31, 2007				March 31, 2006				2008 vs. 2007 Change		2007 vs. 2006 Change
Net sales:
Primary distributors	$	31,705	35	%	$	25,956	38	%	$	26,335	39	%	22	%	(1	%)
Direct customers and other distributors		58,038	65	%		42,546	62	%		40,689	61	%	36	%	5	%
Total	$	89,743	100	%	$	68,502	100	%	$	67,024	100	%

Fiscal Year 2008 versus Fiscal Year 2007

Net sales to our two primary distributors, Future and Nu Horizons, for fiscal year 2008, included $9.7 million in sales of the products acquired in the Sipex merger. Furthermore, as a result of transitioning revenue recognition used for sales to our two primary distributors from the sell-in to the sell-through method as of August 26, 2007, we estimate net sales for fiscal year 2008 were lower by $6.9 million.

Net sales to direct customers and other distributors for fiscal year 2008 included $18.4 million in sales of the products acquired in the Sipex merger.

Fiscal Year 2007 versus Fiscal Year 2006

Net sales for fiscal year 2007 to our two primary distributors, Future and Nu Horizons, decreased 1% compared to fiscal year 2006, was primarily due to price erosion on a limited number of communications products, partially offset by increased sales volumes. Net sales to our direct customers and other distributors in fiscal year 2007 increased 5% compared to fiscal year 2006 primarily due to increased sales volume of network and transmission products to Alcatel-Lucent partially offset by the completion of another customer’s program.

Net Sales by Geography

The following table shows net sales by geography in absolute dollars and as a percentage of net sales for the periods indicated (in thousands):

	March 30, 2008				March 31, 2007				March 31, 2006				2008 vs. 2007 Change		2007 vs. 2006 Change
Net sales:
Americas	$	27,626	31	%	$	30,163	44	%	$	32,969	49	%	(8	%)	(9	%)
Asia		39,953	44	%		20,322	30	%		19,649	29	%	97	%	3	%
Europe		22,164	25	%		18,017	26	%		14,406	22	%	23	%	25	%
Total	$	89,743	100	%	$	68,502	100	%	$	67,024	100	%

47

Fiscal Year 2008 versus Fiscal Year 2007

Net sales in the Americas for fiscal year 2008 included $5.6 million in sales of products acquired in the Sipex merger. We estimate the change of revenue recognition to a sell-through basis at our two primary distributors decreased our net sales in the Americas by $6.9 million for fiscal year 2008.

Net sales in Asia and Europe for fiscal year 2008 included $17.2 million and $5.3 million, respectively, of sales of products acquired in the Sipex merger.

Fiscal Year 2007 versus Fiscal Year 2006

Net sales in the Americas decreased in fiscal year 2007 compared to fiscal year 2006 primarily due to price erosion on a limited number of communications products and the completion of a customer’s program. Net sales in Europe increased during the same period due in part to sales of network and transmission products to Alcatel-Lucent.

Gross Profit

The following table shows gross profit in absolute dollars and as a percentage of net sales for the periods indicated (in thousands):

	March 30, 2008				March 31, 2007				March 31, 2006				2008 vs. 2007 Change		2007 vs. 2006 Change
Net sales	$	89,743			$	68,502			$	67,024
Gross profit	$	40,112	45	%	$	46,534	68	%	$	45,475	68	%	(14	%)	2	%

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 manufacturing engineering;

• the amortization of purchased intangible assets in connection with acquisitions; and

• the provision for excess and obsolete inventory.

Fiscal Year 2008 versus Fiscal Year 2007

The decrease in gross profit for fiscal year 2008 was primarily due to lower gross margins of Sipex’s products, an incremental amortization expense of $4.5 million associated with the purchased intangible assets as a result of the Sipex merger, the amortization of the fair value adjustment to acquired inventories of $2.2 million and charges associated with excess and obsolete inventories. The amortization expense for the purchased intangible assets for the same period a year ago was $1.0 million.

In fiscal year 2008, we fully amortized the fair value adjustment of acquired Sipex inventories recorded in the purchase accounting. In addition, we recorded an impairment charge against purchased intangible assets in the fourth fiscal quarter of 2008. As a result, we expect our future amortization expenses will decrease due to the reduced carrying value of the purchased intangible assets and the exclusion of the fair value adjustment.

Stock-based compensation expense recorded in cost of sales was $0.6 million for fiscal year 2008 as compared to $0.1 million for the fiscal year of 2007. The increase in stock-based compensation expense when compared to a year ago, is primarily attributable to assumed unvested stock options in connection with the Sipex merger.

48

Fiscal Year 2007 versus Fiscal Year 2006

The increase in gross profit in the fiscal year 2007 when compared to the fiscal year of 2006, was due to increased sales volume of network access and transmission products and serial communications products, manufacturing efficiencies and yield improvements, partially offset by price erosion on a limited number of products.

Our gross profit will continue to fluctuate due to, among other factors, future fluctuations in net sales, product mix, manufacturing costs, competitive pricing, manufacturing yields, excess and obsolete inventory, merger related expenses, the recognition of the synergy benefits, the reduction of the amortization of the fair value adjustment to acquired inventories and future amortization of any additional licensed technology.

Other Costs and Expenses

Acquired in-process research and development		8,800	10	%		—	—			—	—		100	%	—

Research and Development (“R&D”)

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, test hardware, engineering supplies and services, and use of in-house test equipment; and

• facilities expenses.

Fiscal Year 2008 versus Fiscal Year 2007

The $4.8 million, or 19% increase in R&D expenses for fiscal year 2008 as compared to a year ago was primarily a result of incremental expense of $4.3 million due to the growth of our company as a result of the Sipex merger and $0.4 million in severance costs of our employees, partially offset by lower labor-related costs.

Fiscal Year 2007 versus Fiscal Year 2006

The $1.1 million, or 5% increase in R&D expenses in fiscal year 2007 as compared to fiscal year 2006 resulted primarily from stock-based compensation expense from our adoption of FAS 123R of $1.2 million and depreciation associated with additional upgrades to an advanced tester and licensing of additional engineering design software, partially offset by lower labor-related costs of $1.0 million.

We believe that innovation is critical to our long-term success, and we intend to continue our investments in R&D to enhance our product offerings in order to meet the current and future requirements of our customers and markets. Some aspects of our R&D efforts require significant short-term expenditures, such as mask tooling for new products, the timing of which may cause significant fluctuations in our R&D expenses. In addition, we expect R&D expenses to fluctuate with the licensing of intellectual property, the recognition of the synergy benefits and potential costs of discontinuing certain product development efforts as we optimize our R&D projects.

49

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 purchased intangible assets; and

• facilities expenses.

Fiscal Year 2008 versus Fiscal Year 2007

The $13.0 million, or 52% increase in SG&A expenses for fiscal year 2008, as compared to a year ago, was primarily a result of incremental expense of $8.4 million due to the growth of our company as a result of the Sipex merger, $1.1 million in severance costs of our employees, the amortization of acquired Sipex intangible assets of $0.9 million, other merger related costs of $0.6 million and increased legal costs of $0.5 million partially offset by lower labor-related expenses.

Stock-based compensation expense recorded in SG&A expenses was $3.4 million for fiscal year 2008 as compared to $3.1 million a year ago. The increase in stock-based compensation expense when compared to the same period a year ago is primarily attributable to assumed unvested stock options in connection with the Sipex merger.

Separation costs for certain executive officers were $0.5 million and $1.6 million in fiscal years 2008 and 2007, respectively.

We expect our amortization expenses on the purchased intangible assets will decrease in future periods due to our impairment charge recorded in fiscal year 2008.

Fiscal Year 2007 versus Fiscal Year 2006

The $3.6 million, or 17% increase in SG&A expenses for fiscal year 2007 as compared to fiscal year 2006 was primarily due to stock-based compensation expense from our adoption of FAS 123R of $3.1 million, executive separation costs of $1.6 million, increased sales commission, costs to complete our stock option backdating investigation, legal fees for litigation and FAS 123R implementation costs, partially offset by lower labor-related costs, and reduced depreciation as our enterprise resource planning or ERP system became fully depreciated. Additionally, SG&A expenses in fiscal year 2006 included proxy expenses of $0.9 million and a reimbursement of $0.4 million for proxy expenses to GWA Investments, LLC and GWA Master Fund, L.P.

Fiscal year 2007 SG&A expenses include stock-based compensation expense of $0.4 million in connection with modifications of stock options related to the separations of our former chief executive officer and chief financial officer.

We anticipate that SG&A expenses will continue to fluctuate due to sales commissions, costs associated with business development, integration costs, amortization of acquired intangible assets, merger related expenses, the recognition of synergy benefits and professional fees. In the short term, many of the SG&A expenses are fixed; however, we expect SG&A expense will continue to fluctuate.

Goodwill and Other Intangible Asset Impairment

In the fourth fiscal quarter of 2008, we conducted our annual impairment review and determined that, based on the 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 as per FAS 142 and recorded a goodwill impairment charge of approximately $128.5 million which was included in the “Goodwill and other intangible asset impairment” line item in the consolidated statements of operations (See Note 2 – Accounting Policies). 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 12.5% and 18.8%. See Part II, Item 8 – “Financial Statements and Supplementary Data” and “Notes to consolidated financial statements, Note 8 – Goodwill and Intangible Assets” for more details about our goodwill.

During the fourth fiscal quarter of 2008, we concluded that our market capitalization was below our net book value for an extended period of time and as a result, the long-lived assets were tested for recoverability. The sales and margin projections for Sipex products have declined due to the impact of the weakening economy, delays in sales ramp up of new high margin proprietary products, and delays in achieving manufacturing cost reductions initially projected. As a result, 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 as per FAS 144 and recorded an impairment charge of approximately $36.7 million which was included in the “Goodwill and other intangible asset impairment” line item in the consolidated statements of operations (See Note 2 –Accounting Policies). 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%. See Part II, Item 8 – “Financial Statements and Supplementary Data” and “Notes to consolidated financial statements, Note 8 – Goodwill and Intangible Assets” for more details about our other intangible assets.

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

Acquired In-Process Research and Development

We recorded a charge of $8.8 million in acquired in-process research and development (“IPR&D”), associated with our merger with Sipex in the three months ended September 30, 2007. We allocated the purchase price related to IPR&D through established valuation techniques. IPR&D was expensed upon acquisition because technological feasibility had not been established and no future alternative uses existed. The fair value of technology under development is determined using the income approach, which discounts expected future cash flows to present value, taking into account 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 derived from the IPR&D were discounted at discount rates ranging from 25% to 40%. The percentage of completion for these projects ranged from 20% to 87% at the merger date.

The IPR&D projects underway at Sipex at the merger date were in the interface and power management product families. Within interface, 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, DC-DC regulators and controllers. All of these projects require further development and testing to bring them up to production. IPR&D projects for power management required $2.2 million to complete and some product shipments began in late calendar year 2007. IPR&D projects for interface are expected to require $0.8 million to complete with expected revenue generation beginning in mid calendar year 2008. All power management and interface projects are scheduled to complete by the end of fiscal year 2009.

If the projects discussed above are not successfully developed and/or successfully marketed, our sales and profitability may be adversely affected in future periods.

Interest Income and Other, Net

Interest income and other, net primarily consists of:

• interest income;

• realized gains (losses) on marketable securities;

• foreign exchange gains or losses; and

• gains or losses on the sale or disposal of equipment.

Fiscal Year 2008 versus Fiscal Year 2007

The $0.5 million or 3% decrease in interest income and other, net during fiscal year 2008 as compared to fiscal year 2007 was primarily attributable to a decrease in interest income as a result of lower invested cash balances partially offset by market interest rates. Cash and short-term investments balances decreased $87.2 million during fiscal year 2008 as compared to fiscal year 2007 primarily as result of stock repurchases of 9.3 million shares totaling $93.0 million.

Fiscal Year 2007 versus Fiscal Year 2006

The $4.2 million, or 34% increase in interest income and other, net during fiscal year 2007 as compared to fiscal year 2006 resulted principally from higher interest income of $4.2 million as a result of higher market interest rates partially offset by increased investments in tax preferred securities that have a lower pre-tax yield.

We expect that our interest income will continue to fluctuate due to changes in interest rates. Starting in the first fiscal quarter of 2009, we are expecting to receive sublease income from our Hillview facility. See Part II, Item 8 – “Financial Statements and Supplementary Data” and “Notes to Consolidated Financial Statements, Note 20 – Subsequent Event.”

Interest expense

In connection with our merger with Sipex, we assumed a lease financing obligation related to a facility, located at 233 South Hillview Drive in Milpitas, California (the “Hillview facility”). We have accounted for this sale and leaseback transaction as a financing transaction which was included in the “Long-term lease financing obligation” line item on the consolidated balance sheet. The effective interest rate is 8.2%. The interest expense in fiscal year 2008 is primarily attributable to the Hillview facility financing transaction.

Other-than-Temporary Loss on Long-Term Investments

Our long-term investments consist of the investments in TechFarm Ventures L.P. (Q), 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

52

networking industry. We account for these non-marketable equity securities under the cost method. In accordance with EITF 03-1, The Meaning of Other-Than-Temporary Impairment and its Application to Certain Investments, we periodically review and determine whether the investments are other-than-temporarily impaired, in which case the investments are written down to their impaired value.

TechFarm Fund

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

In fiscal year 2007, we determined that the TechFarm Fund management fees continued to deplete the fund capital without any appreciation in the valuation of portfolio companies and concluded that a portion of the carrying value of our investment in the fund was other-than-temporarily impaired. As a result, we recorded a $0.1 million impairment charge in September 2006.

In fiscal year 2006, we assessed the value of certain discontinued companies and the remaining portfolio companies within the TechFarm Fund and we believed that the carrying value of our investment in the fund was permanently impaired. As a result, we recorded a $1.2 million impairment charge in December 2005.

Skypoint Fund

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.

In fiscal year 2007, we became aware that two Skypoint Fund portfolio companies would be liquidated. We believed a portion of the carrying value of our investment in the fund was permanently impaired. As a result, we recorded a $0.8 million impairment charge against our earnings in September 2006.

In fiscal year 2006, as a result of impairment review, we concluded that the carrying value of certain portfolio companies in the fund had declined in value and recorded a $0.6 million impairment charges.

Provision for Income Taxes

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 2007

Our effective tax rate for fiscal year 2007 was 29.2%. The provision for fiscal year 2007 differs from the amount computed by applying the statutory federal rate of 35%. This difference is principally due to benefits claimed for tax-exempt interest and research and development tax credits generated during the fiscal year, partially offset by state income taxes and stock-based compensation not currently deductible.

Fiscal Year 2006

Our effective tax rate for fiscal year 2006 was 26.4%. The provision for income taxes for fiscal year 2006 differs from the amount computed by applying the statutory federal rate of 35%. This difference is principally

due to benefits claimed for research and development tax credits generated during the fiscal year, partially offset by state income taxes.

Fiscal Year 2008

Our net loss was $195.9 million. After adjustments for non-cash items and changes in working capital, we generated $13.8 million of cash from operating activities.

Significant non-cash charges included:

• Goodwill and other intangible assets impairment charge of $165.2 million;

• Deprecation and amortization expenses of $12.6 million;

• Acquired IPR&D expense of $8.8 million; and

• Stock-based compensation expense of $5.0 million.

Working capital changes included:

• a $6.8 million increase in accounts receivable primarily due to increased net sales;

• a $3.8 million decrease in other accrued expenses as a result of payments of liabilities acquired in connection with the Sipex merger; and

• a $10.0 million increase in deferred income and allowances on sales to distributors due to our change in revenue recognition on sales to our two primary distributors.

In fiscal year 2008, net cash provided by investing activities reflects net sales of short-term marketable securities of $91.2 million partially offset by $4.9 million in purchases of property, plant and equipment and intellectual property and $2.9 million in net assets acquired in the acquisition of Sipex. The purchases of property, plant and equipment and intellectual property includes $3.2 million associated with the purchase of FyreStorm Inc.’s intellectual property.

54

In fiscal year 2008, net cash used in financing activities reflects the repurchase of $93.0 million, or 9.3 million shares of our common stock in fiscal year 2008 and the $5.3 million repayment of bank borrowings partially offset by $4.3 million of proceeds associated with our employee stock plans.

As of March 30, 2008, we have funded $4.3 million of our $5.0 million committed capital in the Skypoint Fund. We are obligated to contribute our remaining committed capital of approximately $0.7 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 common stock in the open market to partially offset dilution from our stock awards program, 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 stock purchase program, 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 established a new share repurchase plan (“2007 SRP”) and authorized the repurchase of up to $100 million of our common stock over the next twelve months. 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.

The shares repurchased under the 2001 SRP fully utilized the $40 million authorization in the fiscal year of 2007. As of March 30, 2008, the remaining authorized amount for stock repurchase under the 2007 SRP was $25.3 million with no termination date.

Fiscal Year 2007

Net income, adjusted for non-cash related items provided cash of $23.0 million during fiscal year 2007.

In fiscal year 2007, net cash used in investing activities reflects net purchases of $93.0 million of short-tem marketable securities and $3.0 million of purchases of property, plant and equipment and intellectual property.

In fiscal year 2007, net cash provided by financing activities was primarily attributable to $15.8 million of proceeds associated with our employee stock plans, partially offset by the repurchase of approximately 748,000 shares for $9.9 million under the stock repurchase program authorized in March 2001.

Fiscal Year 2006

Net income, adjusted for non-cash related items, provided cash of $19.8 million during fiscal year 2006. Changes in working capital accounts included:

• a $6.8 million increase in accounts primarily due to higher sales in the fourth quarter; and

• a $1.9 million increase in inventories based on higher projected sales.

In fiscal year 2006, net cash provided by investing activities reflects net sales of $46.9 million of short-term marketable securities partially offset by $11.4 million acquisition for Optical Networking Business Unit of Infineon Technologies A.G. (“ON”) in April 2005, and purchases of property, plant and equipment and intellectual property of $5.9 million which consisted primarily of purchases for test equipment.

In fiscal year 2006, net cash used in financing activities was primarily due to the repurchase of 7.5 million shares of our common stock for $120.0 million and associated costs of $0.8 million in connection with our tender offer. Additionally, we repurchased 270,000 shares of our common stock for $3.6 million under the stock repurchase program authorized in March 2001. This was partially offset by the proceeds of $11.6 million from the stock option exercised by our employees.

55

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. 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 and capital equipment 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. There can be no assurance that additional financing could be obtained on terms acceptable to us. The sale of additional equity or convertible debt could result in dilution to our stockholders.

OFF-BALANCE SHEET ARRANGEMENTS

As of March 30, 2008, we had no off-balance sheet arrangements as defined in Item 303(a)(4) of the SEC’s Regulation S-K.

Note: The table above excludes the liability for uncertain tax positions of approximately $1,023,000 at March 30, 2008 since we cannot predict with reasonable reliability the timing of cash settlements with the respective taxing authorities.

(1) We place purchase orders with wafer foundries and other vendors as part of our normal course of business. We expect to receive and pay for wafers, capital equipment and various service contract over the next 12 to 18 months from our existing cash balances.

(2) Lease payments excluding $12.2 million estimated final obligation settlement with the lessor by returning the Hillview facility at the end of lease term due on our Hillview facility in Milpitas, California under a 5-year Standard Form Lease agreement that we signed with Mission West Properties L.P. on March 9, 2006, as amended on August 25, 2007. It also includes a $4.7 million licensing agreement related to engineering design software.

(3) Includes lease payments related to worldwide offices and buildings.

(4) The commitment related to the Skypoint Fund does not have a set payment schedule and thus will become payable upon the request from the Fund's General Partner.

(5) The commitment relates to the environmental remediation activities of Micro Power Systems, Inc.

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 year ended March 30, 2008, we did not have significant foreign currency denominated net assets or net liabilities positions, and had no foreign currency contracts outstanding.

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, money market funds and fixed income securities of $267.7 million as of March 30, 2008 and $355.1 million as of March 31, 2007. 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 30, 2008, the increase or decline in the fair value of the portfolio would not be material. At March 30, 2008, the difference between the fair market value and the underlying cost of the investments portfolio was an unrealized gain of $1.9 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 30, 2008, short-term investments consisted of commercial paper, asset-backed securities, corporate bonds and government securities of $146.8 million.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders 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 30, 2008 and March 31, 2007, and the results of their operations and their cash flows for each of the three years in the period ended March 30, 2008 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 30, 2008, 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 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 2 to the consolidated financial statements, the Company changed the manner in which it accounts for uncertain tax positions in fiscal year 2008 and the manner in which it accounts for share-based compensation in fiscal year 2007.

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 30, 2008, MARCH 31, 2007 AND MARCH 31, 2006

NOTE 1.    DESCRIPTION OF BUSINESS

Exar Corporation and its subsidiaries (“Exar” or “we”) was incorporated in California in 1971 and reincorporated in Delaware in 1991. We are a fabless semiconductor company that designs, develops, markets and sells power management and connectivity silicon solutions. 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 and industrial automation equipment.

On August 25, 2007, we acquired Sipex Corporation (“Sipex”) through the merger of Sipex and a subsidiary of Exar. Sipex was a company that designed, manufactured and marketed high performance, analog integrated circuits (“IC”) used by original equipment manufacturers (“OEM”), in the computing, consumer electronics, communications and networking infrastructure markets. The results of operations of Sipex and estimated fair value of assets acquired and liabilities assumed were included in our consolidated financial statements beginning August 26, 2007.

NOTE 2.    ACCOUNTING POLICIES

Basis of Presentation—In December 2007, we changed our fiscal year end from March 31 to a 52-53 week fiscal year ending on the Sunday closest to March 31. As part of this change, each fiscal quarter will also end on the Sunday closest to the end of the corresponding calendar quarter. The third fiscal quarter of 2008 included 91 days from October 1, 2007 to December 30, 2007. The fourth fiscal quarter of 2008 included 91 days from December 31, 2007 to March 30, 2008. Hereinafter, the fiscal years ended March 30, 2008, March 31, 2007 and March 31, 2006 are also referred to as “2008,” “2007” and “2006” unless otherwise indicated.

Certain amounts previously reported have been reclassified to conform to the presentation of the fiscal year of 2008.

In conjunction with the Sipex merger, we reassessed our ability to estimate returns and allowances and consequently, on August 26, 2007, changed the revenue recognition used for sales to our two primary distributors, Future Electronics Inc. (“Future”) and Nu Horizons Electronics Corp. (“Nu Horizons”), from sell-in basis to sell-through basis (See Note 2 – Accounting Policies, Revenue Recognition).

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.

The accounts of foreign subsidiaries have been remeasured into U.S. Dollars in accordance with the Financial Accounting Standards Board (“FASB”) Statement of Financial Accounting Standards No. 52, Foreign Currency Translation (“FAS 52”). Accordingly, foreign currency is remeasured to U.S. Dollars for financial 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 and other income, 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 and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. The functional currency of Exar and its significant subsidiaries is the U.S. Dollar.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)

FISCAL YEARS ENDED MARCH 30, 2008, MARCH 31, 2007 AND MARCH 31, 2006

Use of Management Estimates—The preparation of consolidated financial statements in conformity with 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 based on management estimates as per Statement of Financial Accounting Standards No. 141, Business Combinations (“FAS 141”). The purchase price includes direct transaction costs consisting of investment banking, legal and accounting fees.

Cash and Cash Equivalents—We consider all highly liquid debt securities and investments with a maturity from the date of purchase of 90 days or less to be classified as 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 either six or twelve months of demand, as judged by management, for each specific product.

Our inventories consisted of the following (in thousands):

	March 30, 2008		March 31, 2007
Work-in-process	$	8,775	$	2,426
Finished goods		5,426		2,353
Inventories	$	14,201	$	4,779

Property, Plant and Equipment—Property, plant and equipment, including 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.

FISCAL YEARS ENDED MARCH 30, 2008, MARCH 31, 2007 AND MARCH 31, 2006

Our property, plant and equipment consisted of the following (in thousands):

	March 30, 2008			March 31, 2007
Land	$	11,960		$	6,660
Buildings		22,584			14,350
Machinery and equipment		65,215			52,670

Accumulated depreciation and amortization		(53,629	)		(48,276	)
Property, plant and equipment, net	$	46,130		$	25,404

Depreciation and amortization expense for the fiscal years ended March 30, 2008, March 31, 2007 and March 31, 2006 was $5.9 million, $4.6 million, and $5.1 million, respectively.

Non-Marketable Equity Securities—Non-marketable equity securities are presented on our consolidated balance sheets as long-term investments. They are accounted for at historical cost and are subject to a periodic impairment review. This impairment analysis requires significant judgment to identify events or circumstances that would likely have a significant adverse effect on the fair value of the investment. The indicators 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, in which case 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 securities is recorded in the “Other-than-temporary loss on long-term 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 follow the provisions of Statement of Financial Accounting Standards No. 142, Goodwill and Other Intangible Assets (“FAS 142”), under which goodwill is no longer subject to amortization. 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 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, if any. Because we have one reporting unit under FAS 142, we utilized an entity-wide approach to assess goodwill for impairment. We performed our annual goodwill impairment analysis during the fourth fiscal quarter of 2008 pursuant to the steps and requirements under FAS 142 and recorded a $128.5 million impairment loss which was included in the “Goodwill and other intangible asset impairment” line item in the consolidated statements of operations. (See Note 8 – Goodwill and Intangible Assets).

Long-Lived Assets—Our long-lived assets include land, buildings, equipment, furniture and fixtures, privately held equity investments 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

65

EXAR CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)

FISCAL YEARS ENDED MARCH 30, 2008, MARCH 31, 2007 AND MARCH 31, 2006

recoverable. We evaluate the recoverability of our long-lived assets in accordance with Statement of Financial Accounting Standards No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets (“FAS 144”). 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 the fourth fiscal quarter of 2008, we concluded that our market capitalization was below its net book value for an extended period of time and, as a result, long-lived assets were tested for recoverability. We determined that the carrying value of intangible assets acquired in the Sipex merger exceeded the fair value. We used the income approach to determine the fair value of these intangible assets. The evaluation resulted in an impairment charge of $36.7 million against intangible assets which was included in the “Goodwill and other intangible asset impairment” line item in the consolidated statements of operations (See Note 8 —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—Income taxes are reported under Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes (“FAS 109”) and accordingly, 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.

On April 1, 2007, we adopted the provisions of FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes – an interpretation of FASB Statement No. 109 (“FIN 48”), which provides a financial statement recognition threshold and measurement attribute for a tax position taken or expected to be taken in a tax return. Under FIN 48, we may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. FIN 48 also provides guidance on derecognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, and income tax disclosures. The cumulative effect of adopting FIN 48 was a decrease in the liability for uncertain tax positions and an increase of $0.2 million to the April 1, 2007 opening retained earnings balance.

Revenue Recognition—We recognize revenue in accordance with the Securities and Exchange Commission (“SEC”) Staff Accounting Bulletin 104, Revenue Recognition (“SAB 104”). SAB 104 requires that four basic criteria must be met before revenue can be recognized: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services 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 the fiscal years ended March 30, 2008, March 31, 2007 and March 31, 2006, approximately 35%, 38% and 39%, respectively, of our net sales were derived from sales to our two primary distributors, Future and Nu Horizons; and approximately 65%, 62% and 61%, respectively, of our net sales were derived from product sales to other distributors, OEM customers and other non-distributors.

EXAR CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)

FISCAL YEARS ENDED MARCH 30, 2008, MARCH 31, 2007 AND MARCH 31, 2006

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, title has transferred, 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:

Our two primary distributors’ agreements 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 to each of our distributors using either of the methodologies in the following table. Once adopted, the revenue methodology for a distributor will be maintained unless there is a change in circumstances indicating the methodology for that distributor is no longer appropriate.

• Sell-in Basis: Revenue is recognized upon shipment if we conclude 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 returns, pricing allowance 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 is 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 revenues, gross margin, deferred income and allowances on sales to distributors and net income.

Our historical patterns of returns, pricing allowances and other concessions with distributors have been fairly consistent, which has enabled us to reasonably estimate such allowances at the time of shipment. Therefore, we have historically recognized revenue on sales to all distributors on a sell-in basis and recorded an estimated allowance, at the time of shipment, based on authorized and historical patterns of returns and other

67

EXAR CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)

FISCAL YEARS ENDED MARCH 30, 2008, MARCH 31, 2007 AND MARCH 31, 2006

concessions. Concurrent with the merger with 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 merger, Sipex recognized revenue on sales to all distributors on a sell-through basis. Consistent with Sipex’s past practice, we have concluded that we are not able to reasonably estimate such allowances at the time of shipment of products to Sipex’s distributors. Therefore, we have determined that consistent with Sipex’s past practice, we will continue to recognize sales to Sipex’s distributors on a sell-through basis. In addition, as a result of the merger, our relationships, marketing and sales practices with our two primary distributors have changed. Further, as disclosed Part II, Item 8—“Financial Statements and Supplementary Data” and “Notes to Consolidated Financial Statements, Note 5—Related Party Transaction,” Future is now 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, as of August 26, 2007, we determined it was appropriate that revenue on all sales to Future and Nu Horizons be recognized on a sell-through basis.

Research and Development Expenses—Research and development expenses consist primarily of the salaries and related expenses of those employees engaged in research, design and development activities; expenses related to design tools, license expenses related to intellectual property; mask tooling costs; supplies and services; and facilities expenses. All research and development expenses that have no alternative future use are expensed as incurred.

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 the fiscal years ended March 30, 2008, March 31, 2007 and March 31, 2006 has been disclosed within the consolidated statements of stockholders’ equity and comprehensive income (loss).

Foreign Currency—The accounts of foreign subsidiaries are remeasured into U.S. Dollars in accordance with the Statement of Financial Accounting Standards No. 52, Foreign Currency Translation (“FAS 52”). Accordingly, 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. Foreign currency transaction losses were approximately $65,000, $20,000 and $34,000 for the fiscal years ended March 30, 2008, March 31, 2007 and March 31, 2006, respectively.

Concentration of Credit Risk and Significant Customers—Financial instruments potentially subjecting us to concentrations of credit risk consist primarily of accounts receivable, cash, cash equivalents, short-term marketable securities 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 the fiscal years ended March 30, 2008, March 31, 2007 and March 31, 2006, respectively. Our policy is to place 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.

68

EXAR CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)

FISCAL YEARS ENDED MARCH 30, 2008, MARCH 31, 2007 AND MARCH 31, 2006

We sell our products to distributors and OEMs throughout the world. Alcatel-Lucent accounted for 11%, 16% and 12% of our net sales for the fiscal years of 2008, 2007 and 2006, respectively. No other OEM customer accounted for 10% or more of our net sales for any of the three fiscal years of 2008, 2007 and 2006. Future, a related party, was and continues to be our largest distributor. Future, on a worldwide basis, represented 24%, 20% and 24% of net sales in fiscal years 2008, 2007 and 2006, respectively. Our second largest distributor, Nu Horizons, accounted for 11%, 18%, and 15%, of net sales in fiscal years of 2008, 2007 and 2006, respectively.

Concentration of Other Risks—The majorities of our products are currently fabricated at Chartered Semiconductor Manufacturing Ltd. (“Chartered”) in Singapore, Episil Technologies Inc. (“Episil”) in Taiwan, and Hangzhou Silan Microelectronics Co. Ltd. and Hangzhou Silan Integrated Circuit Co. Ltd. (collectively “Silan”) in China, 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.

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 investments, accounts receivable, accounts payable and accrued liabilities at March 30, 2008 and March 31, 2007 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—On April 1, 2006, we adopted Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment (“FAS 123R”) by using the modified prospective transition method. In accordance with this transition method, we began recognizing compensation expense for all share-based awards granted after April 1, 2006 plus unvested awards granted prior to April 1, 2006. Under this method of implementation, no restatement of prior periods has been made. 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, expected term and risk-free 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.

Recent Accounting Pronouncements

In May 2008, the FASB issued Statement of Financial Accounting Standards No. 162, The Hierarchy of Generally Accepted Accounting Principles (“FAS 162”). The new standard is intended to improve financial reporting by identifying a consistent framework, or hierarchy, for selecting accounting principles to be used in preparing financial statements that are presented in conformity with U.S. generally accepted accounting principles (“GAAP”) for nongovernmental entities. FAS 162 is effective 60 days following SEC approval of the Public Company Accounting Oversight Board Auditing amendments to AU Section 411, The Meaning of Present Fairly in Conformity with Generally Accepted Accounting Principles. We are currently evaluating the impact, if any, of the adopting the FAS 162, on our financial position, results of operations and liquidity.

In December 2007, the FASB issued Statement of Financial Accounting Standards No. 141 (revised 2007) (“FAS 141R”), Business Combinations, which replaces FAS 141. The statement retains the purchase method of

69

EXAR CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)

FISCAL YEARS ENDED MARCH 30, 2008, MARCH 31, 2007 AND MARCH 31, 2006

accounting for acquisitions, but requires a number of changes, including changes in the way assets and liabilities are recognized in the purchase accounting. It also changes the recognition of assets acquired and liabilities assumed arising from contingencies, requires the capitalization of in-process research and development at fair value, and requires the expensing of acquisition-related costs as incurred. FAS 141R is effective for financial statements issued for fiscal years beginning after December 15, 2008 and will apply prospectively to business combinations completed on or after that date. We are currently evaluating the impact of implementing FAS 141R on our financial position, results of operations and liquidity.

In February 2007, the FASB issued Statement of Financial Accounting Standards No. 159, The Fair Value Option for Financial Assets and Financial Liabilities (“FAS 159”). FAS 159 permits companies to choose to measure certain financial instruments and certain other items at fair value. The standard requires that unrealized gains and losses on items for which the fair value option has been elected be reported in earnings. FAS 159 is effective for financial statements issued for fiscal years beginning after November 15, 2007, although earlier adoption is permitted. As of March 31, 2008, the first day of our fiscal year 2009, we adopted FAS 159 and the adoption had no material impact on our financial position, results of operations and liquidity.

In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157 (“FAS 157”), Fair Value Measurements, which defines fair value, establishes a framework and provides guidance regarding the methods used for measuring fair value, and expands disclosures about fair value measurements. In February 2008, the FASB issued FASB Staff Position (“FSP”) FAS 157-1, Application of FASB Statement No. 157 to FASB Statement No. 13 and Other Accounting Pronouncements That Address Fair Value Measurement for Purpose of Lease Classification or Measurement under Statement 13, which amends FAS 157 to exclude accounting pronouncements that address fair value measurements for purposes of lease classification or measurement under FAS 13, Accounting for Leases. In February 2008, the FASB also issued FSP FAS 157-2, Effective Date of FASB Statement No. 157, which delays the effective date of FAS 157 until the first fiscal quarter of 2010 for all non-financial assets and non-financial liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually). FAS 157 does not require any new fair value measurement but rather eliminates inconsistencies in guidance found in various prior accounting pronouncements. FAS 157 is effective for financial statements issued for the fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. As of March 31, 2008, the first day of our fiscal year 2009, we adopted FAS 157 and the adoption had no material impact on our financial position, results of operations and liquidity.

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.

Merger with Sipex Corporation

On August 25, 2007, we completed our merger with Sipex, a company that designed, manufactured and marketed high performance, analog ICs used by OEMs in the computing, consumer electronics, communications and networking infrastructure markets. As a result of the merger, we have combined product offerings, increased technical expertise, distribution channels, customer base and geographic reach as well as reduced expenses due to significant cost synergies.

Each share of Sipex’s common stock outstanding at the effective time of the merger was converted into 0.6679 shares of our common stock. As a result, approximately 16.5 million shares of our common stock were

issued. The fair value of the common stock issued was determined using a share price of $13.97, which represented the average closing price of our common stock for two trading days before and two trading days after May 8, 2007, the date the merger was announced. We assumed stock options to purchase approximately 2.2 million shares of our common stock. The fair value of options assumed was estimated by using the Black-Scholes option pricing model and a share price of $13.97. In addition, in connection with the merger, we assumed warrants to purchase 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. The fair value of $5.31 for each warrant assumed was estimated by using the Black-Scholes option pricing model and a share price of $13.97.

The merger was accounted for as a purchase in accordance FAS 141. Accordingly, the results of operations of Sipex and estimated fair value of assets acquired and liabilities assumed were included in our consolidated financial statements beginning August 26, 2007.

The total estimated purchase price of the merger was as follows (in thousands):

	Amounts
Fair value of Exar common stock issued	$	229,999
Fair value of options and warrants assumed		16,701
Direct transaction costs		4,038
Total estimated purchase price	$	250,738

Purchase Price Allocation

The allocation of the purchase price to Sipex’s tangible and identifiable intangible assets acquired and liabilities assumed was based on their estimated fair values. The excess of the purchase price over the tangible and identifiable intangible assets acquired and liabilities assumed has been allocated to goodwill. Goodwill resulted primarily from our expectations of synergies from integration of Sipex’s product offerings with our product offerings. Goodwill is not deductible for tax purposes. We have up to twelve months from the closing date of the merger to adjust any pre-acquisition contingencies, if any.

We recorded net adjustments totaling approximately $187,000 to our goodwill during the fiscal year ended March 30, 2008. The adjustments were primarily due to an increase in the fair value of acquired inventory from a recovery of approximately $220,000 and a decrease in the fair value of our severance costs accrual of $381,000, which was partially offset by an increase in the fair value of our facility costs accrual by approximately $338,000 resulting primarily from our Billerica lease termination.

During the same period, we recorded a goodwill impairment loss of approximately $128.5 million associated with the Sipex merger (See Note 8 – Goodwill and Intangible Assets).

Identifiable Intangible Assets

The following table set forth the components of the identifiable intangible assets purchased with the merger, which are being amortized over their estimated useful lives on a straight-line basis (in thousands):

Acquired In-Process Research and Development

We recorded a charge of $8.8 million in acquired in-process research and development (“IPR&D”), associated with our merger with Sipex in the fiscal quarter ended September 30, 2007. We allocated the purchase price related to IPR&D through established valuation techniques. IPR&D was expensed upon acquisition because technological feasibility had not been established and no future alternative uses existed. The fair value of technology under development is determined using the income approach, which discounts expected future cash flows to present value, taking into account 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 derived from the IPR&D were discounted at discount rates ranging from 25% to 40%. The percentage of completion for these projects ranged from 20% to 87% at the merger date.

The IPR&D projects underway at Sipex at the merger date were in the interface and power management product families. Within interface, 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, DC-DC regulators and controllers. All of these projects require further development and testing to bring them up to production. IPR&D projects for power management required $2.2 million to complete and some product shipments began in late calendar year 2007. IPR&D projects for interface required $0.8 million to complete with expected revenue generation beginning in mid calendar year 2008. All power management and interface projects are scheduled to be completed by the end of the fiscal year of 2009.

If the projects discussed above are not successfully developed and/or successfully marketed, our sales and profitability may be adversely affected in future periods.

Pro Forma Financial Information

The following unaudited pro forma financial information was based on the respective historical financial statements of Exar and Sipex. The unaudited pro forma financial information reflected the consolidated results of operations as if the merger of Sipex occurred at the beginning of each period and included the amortization of the resulting identifiable acquired intangible assets, effects of the estimated write-up of Sipex inventory to fair value on cost of goods sold, the exclusion of interest expense on Sipex’s senior convertible notes and stock-based compensation expenses. These unaudited pro forma financial information adjustments reflect their related tax effects. The pro forma data for the fiscal years ended March 30, 2008 and March 31, 2007 also included a non-recurring charge of $8.8 million for acquired IPR&D. The unaudited pro forma financial data is provided for illustrative purposes only and is not necessarily indicative of the consolidated results of operations for future periods or that actually would have been realized had Exar and Sipex been a consolidated entity during the periods presented.

Total short-term marketable securities	$	146,844	$	236,270

Our marketable securities include municipal securities, commercial paper, asset-backed securities, corporate bonds and government securities. We classify investments as available-for-sale at the time of purchase and re-evaluate such designation as of each consolidated balance sheet date. We amortize premiums and accrete discounts to interest income over the life of the investment. Our available-for-sale securities are classified as cash equivalents if the maturity from the date of purchase is ninety days or less, and as short-term investments for those with maturities, from the date of purchase, in excess of ninety days 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 consolidated balance sheet date, with unrealized gains or losses recorded in accumulated other comprehensive income (loss) within stockholders’ equity except those unrealized losses that are deemed to be other than temporary which are reflected in the other income and expense section in the consolidated statement of operations.

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 the fiscal year ended March 30, 2008 were $174,000. For the fiscal year ended March 31, 2007, there were $52,000 in net realized gains. For the fiscal year ended March 31, 2006, there were $7,000 in net realized losses on marketable securities.

We review our investment portfolio to identify and evaluate investments that have indications of possible impairment. Factors considered in determining whether a loss is temporary include the length of time and extent to which fair value has been less than the cost basis, the financial condition and near-term prospects of the investee, credit quality and our ability to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value. We determined that such amounts were not “other-than-temporary” as defined by the Statement of Financial Accounting Standards No. 115, Accounting for Certain Investments in Debt and Equity Securities (“FAS 115”).

NOTE 5.    RELATED PARTY TRANSACTION

Affiliates of Future, Alonim Investments Inc. and its two affiliates (collectively “Alonim”), own approximately 7.7 million shares or approximately 18% of our outstanding common stock as of March 30, 2008. 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 the distribution agreement when Future sells the products to end customers. Future has historically accounted for a significant portion of our net sales. It is our largest distributor worldwide and accounted for 24%, 20% and 24% of our total net sales for the fiscal years ended March 30, 2008, March 31, 2007 and March 31, 2006, respectively.

FISCAL YEARS ENDED MARCH 30, 2008, MARCH 31, 2007 AND MARCH 31, 2006

We reimbursed Future for approximately $56,000, $6,000 and $2,000 of expenses for marketing promotional materials for the fiscal years ended March 30, 2008, March 31, 2007 and March 31, 2006, respectively.

Upon our merger with Sipex, we appointed an executive vice president and chief financial officer of Future to our board of directors. Our board of directors has determined that this director is not independent within the meaning of The Marketplace Rule 4200(a)(15) of The NASDAQ Stock Market by virtue of our relationship with Future.

In the fourth fiscal quarter of 2006, GWA Investments, LLC and GWA Master Fund, L.P. (collectively “GWA”), requested that we reimburse its costs of $0.4 million in connection with our proxy solicitation in October 2005 in support of their director candidates, all of whom were elected to our board of directors at the 2005 annual meeting of stockholders. GWA was a hedge fund managed by a director of Exar, Guy W. Adams. These costs were included in selling, general and administrative expenses in our consolidated statements of operations for the fiscal year ended March 31, 2006.

NOTE 6.    RESTRUCTURING

In connection with the Sipex merger in August 2007, our management approved and initiated plans to restructure the operations of the combined company to eliminate certain duplicative activities, reduce cost structure and better align product and operating expenses with existing general economic conditions. The Sipex restructuring costs were accounted for as liabilities assumed as part of the purchase business combination in accordance with the Emerging Issues Task Force Issue No. 95-3, Recognition of Liabilities in Connection with a Purchase Business Combination (“EITF 95-3”).

The following table set forth restructuring liabilities which were included in other accrued expenses on the balance sheet, and the activities affecting the liabilities for the period ended March 30, 2008 (in thousands):

	Facility costs			Severance costs			Total restructuring liabilities
Balance at August 25, 2007	$	1,166		$	1,037		$	2,203
Utilization		(1,173	)		(456	)		(1,629	)

Adjustment to accrual		338			(381	)		(43	)
Balance at March 30, 2008	$	491		$	200		$	691

The liabilities established in connection with the Sipex merger included the following:

• A liability of $1.0 million for severance and termination benefits for employees;

• A liability of $0.5 million for facility lease exit cost primarily in our international sites;

• A liability of $0.3 million for facility relocation and other costs; and

• A liability of $0.4 million assumed in connection with our merger with Sipex.

For fiscal year 2008, we paid cash severance of approximately $456,000 and changed our estimates and reduced our restructuring accrual by approximately $381,000. The remaining balance of $200,000 for severance costs was expected to be paid out over the next six months.

For fiscal year 2008, we also utilized approximately $1.2 million of our restructuring accrual, primarily related to moving expenses at our Hillview facility and the lease expenses for the unused portion of the Billerica facility in Massachusetts. During the same period, we recorded an additional liability of $454,000 in connection with the Billerica lease termination and reduced approximately $116,000 restructuring accrual primarily related to the facility relocation. The remaining balance of approximately $0.5 million was expected to be paid during the remaining terms of the lease contracts which extend through 2012.

NOTE 7.    LONG-TERM INVESTMENTS

Our long-term investments consist of the investments in TechFarm Ventures L.P. (Q), 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. In accordance with the EITF 03-1, The Meaning of Other-Than-Temporary Impairment and its Application to Certain Investments, we periodically review and determine whether the investments are other-than-temporarily impaired, in which case the investments are written down to their impaired value.

As of March 30, 2008 and March 31, 2007, our long-term investments balances were as follows (in thousands):

	March 30, 2008		March 31, 2007
TechFarm Fund	$	466	$	466
Skypoint Fund		2,170		2,204
Long-term investments	$	2,636	$	2,670

TechFarm Fund

We have made a total of approximately $4.0 million in capital contributions to TechFarm Fund since we became a limited partner in May 2001. We have reached our total commitment to the fund and made no capital contribution to the fund during both fiscal years 2008 and 2007. As a result, we have no capital contribution obligation to the TechFarm Fund at March 30, 2008.

The approximate carrying amount of $0.5 million at March 30, 2008 reflected the net of the capital contribution and the accumulative impairment charges. We have never received any capital distribution from the fund.

Impairment

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

In fiscal year 2007, we determined that the TechFarm Fund management fees continued to deplete the fund capital without any appreciation in the valuation of portfolio companies and concluded that a portion of the carrying value of our investment in the fund was other-than-temporarily impaired. As a result, we recorded a $0.1 million impairment charge in September 2006.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)

FISCAL YEARS ENDED MARCH 30, 2008, MARCH 31, 2007 AND MARCH 31, 2006

In fiscal year 2006, we assessed the value of certain discontinued companies and the remaining portfolio companies within the TechFarm Fund and we believed that the carrying value of our investment in the fund was permanently impaired. As a result, we recorded a $1.2 million impairment charge in December 2005.

Skypoint Fund

We have made approximately $4.3 million in capital contributions to Skypoint Fund since we became a limited partner in July 2001. Our total capital commitment is $5.0 million. We contributed $0.6 million and $0.9 million to the fund during the fiscal year of 2008 and 2007, respectively. As of March 30, 2008, we have a remaining obligation of approximately $0.7 million to the fund upon its request.

The approximate carrying amount of $2.2 million reflected the net of the capital contribution, accumulative impairment charges and capital distributions. We received a capital distribution of $0.1 million and $0.6 million during the fiscal year of 2007 and 2006, respectively. We did not receive any distribution during the fiscal year of 2008. The distribution was accounted for in accordance to FASB Accounting Principle Bulletin 19, The Equity Method of Accounting for Investments in Common Stock (“APB 18”). We recorded the distribution on the cost basis and reduced the carrying value of our investments in the Skypoint Fund.

Impairment

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.

In fiscal year 2007, we became aware that two Skypoint Fund portfolio companies would be liquidated. We believed a portion of the carrying value of our investment in the fund was permanently impaired. As a result, we recorded a $0.8 million impairment charge against our earnings in September 2006.

In fiscal year 2006, as a result of impairment review, we concluded that the carrying value of certain portfolio companies in the fund had declined in value and recorded a $0.6 million impairment charges.

In the fourth fiscal quarter of 2008, we conducted our annual impairment review and determined that, based on the 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 as per FAS 142 and recorded a goodwill impairment charge of approximately $128.5 million which was included in the “Goodwill and other intangible asset impairment” line item in the consolidated statements of operations (See Note 2 – Accounting Policies). 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 12.5% and 18.8%.

Intangible Assets

Our intangible assets are comprised of intangible assets acquired in connection with our merger with Sipex in August 2007, our acquisition of Fyrestorm’s intellectual property in February 2008 for approximately $3.2 million in cash, our acquisition of the Optical Networking Business Unit of Infineon Technologies A.G. in April 2005 and other individually acquired intellectual properties.

As of March 30, 2008 and March 31, 2007, our purchased intangible assets were as follows (in thousands):

	Gross Carrying Amount		Impairment Loss			Accumulated Amortization			Net Carrying Amount		Gross Carrying Amount		Accumulated Amortization			Net Carrying Amount

During the fourth fiscal quarter of 2008, we concluded that our market capitalization was below our net book value for an extended period of time and as a result, the long-lived assets were tested for recoverability. The sales and margin projections for Sipex products have declined due to the impact of the weakening economy, delays in sales ramp up of new high margin proprietary products, and delays in achieving manufacturing cost reductions initially projected. As a result, 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 as per FAS 144 and recorded an impairment charge of approximately $36.7 million which was included in the “Goodwill and other intangible asset impairment” line item in the consolidated statements of operations (See Note 2 – Accounting Policies). 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 9.    EARNINGS (LOSS) PER SHARE

Basic earnings (loss) per share excludes dilution and is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the periods in accordance with FASB Statement of Financial Accounting Standards No. 128, Earnings Per Share (“FAS 128”). Diluted earnings per share (“EPS”) reflects the potential dilution that would occur if outstanding stock options or warrants to issue common stock, unvested restricted stock units (“RSUs”) and restricted stock awards were exercised or converted into common stock by using the treasury stock method. A summary of our earnings (loss) per share for the three fiscal years of 2008, 2007 and 2006 was as follows (in thousands, except per share amounts):

FISCAL YEARS ENDED MARCH 30, 2008, MARCH 31, 2007 AND MARCH 31, 2006

For the fiscal year ended March 30, 2008, as we incurred a net loss, the weighted average number of common shares outstanding equals the weighted average number of common and common equivalent shares assuming dilution. Approximately 405,000 shares of options and RSUs 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 amounts.

For the fiscal year ended March 30, 2008, approximately 5.2 million options to purchase shares of common stock, at exercise prices ranging from $8.78 to $86.10, were outstanding but were not included in the 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 the 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.

For the fiscal year ended March 31, 2007, approximately 5.0 million options to purchase shares of common stock, at exercise prices ranging from $12.09 to $54.75, were outstanding but were not included in the computation of diluted earnings per share because they were anti-dilutive under the treasury stock method. Unvested restricted stock units of 1,603 with a grant date fair value of $13.40 were outstanding at March 31, 2007 and were not included in the computation of diluted net income per share because they were anti-dilutive under the treasury stock method.

For the fiscal year ended March 31, 2006, approximately 5.2 million options to purchase shares of common stock, at exercise prices ranging from $13.12 to $59.31, were outstanding but were not included in the computation of diluted earnings per share because they were anti-dilutive under the treasury stock method. There were no outstanding unvested RSUs at March 31, 2006.

Our application of the treasury stock method includes assumed cash proceeds from option exercised, 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 10.    COMMON STOCK REPURCHASES

From time to time, we acquire outstanding common stock in the open market to partially offset dilution from our stock awards program, 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 stock purchase program, 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 established a new share repurchase plan (“2007 SRP”) and authorized the repurchase of up to $100 million of our common stock over the next twelve months. 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.

During the fiscal year ended March 30, 2008, we repurchased a total of 9.3 million shares of our common stock at an aggregate cost of $93.0 million under the 2007 SRP and 2001 SRP.

FISCAL YEARS ENDED MARCH 30, 2008, MARCH 31, 2007 AND MARCH 31, 2006

During the fiscal year ended March 31, 2007, we repurchased a total of 0.8 million shares of our common stock at an aggregate cost of $9.9 million under the 2001 SRP.

The shares repurchased under the 2001 SRP fully utilized the $40 million authorization in the fiscal year of 2007. As of March 30, 2008, the remaining authorized amount for stock repurchase under the 2007 SRP was $25.3 million with no termination date.

In July of fiscal year 2006, we commenced a Modified “Dutch Auction” Self Tender Offer (“tender offer”) to acquire up to 7,058,823 shares of our common stock at a purchase price of no greater than $17.00 or less than $15.00 per share. During the fiscal quarter ended September 30, 2005, we completed the tender offer and repurchased 7,500,000 shares of our common stock at a purchase price of $16.00 per share, resulting in aggregate payments of $120.0 million plus costs of approximately $0.8 million.

NOTE 11.    EMPLOYEE BENEFIT PLANS

Exar Savings Plans

The Exar Savings Plan, as amended and restated, covers our eligible U.S. employees. The Exar Savings Plan provides for voluntary salary reduction contributions in accordance with Section 401(k) of the Internal Revenue Code as well as matching contributions from the company based on the achievement of specified operating results. Our matching contributions to the plan were $0.3 million, $0.3 million and $0.6 million for the fiscal years ended March 30, 2008, March 31, 2007 and March 31, 2006, respectively.

Executive and Key Employee Incentive Compensation Programs

Our incentive compensation programs provide for incentive awards for substantially all employees based on the achievement of specified operating and performance results. For the fiscal year ended March 30, 2008, we paid approximately $699,000 in incentive compensation. Unpaid incentive compensation was approximately $600,000 at March 30, 2008. For the fiscal years ended March 31, 2007 and March 31, 2006, we did not incur expense related to the Executive and Key Employee Incentive Compensation Programs. Our incentive compensation programs may be amended or discontinued at the discretion of our board of directors.

NOTE 12.    STOCK-BASED COMPENSATION

On April 1, 2006, we adopted the fair value recognition provisions of FAS 123R by using the modified prospective transition method. In accordance with the modified prospective transition method, we began recognizing compensation expense for all share-based awards granted on or after April 1, 2006, plus unvested awards granted prior to April 1, 2006. Under this method of implementation, no restatement of prior periods has been made. The cumulative effect of adopting FAS 123R was not significant. Under FAS 123R, we use the straight-line attribution method for expensing stock-based compensation which is based on awards ultimately expected to vest and reduced for estimated forfeitures.

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 under FAS 123R.

EXAR CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)

FISCAL YEARS ENDED MARCH 30, 2008, MARCH 31, 2007 AND MARCH 31, 2006

We are authorized to issue 4.5 million shares of common stock under our ESPP. At March 30, 2008, approximately 1,663,000 shares of common stock were reserved for future issuance under our ESPP. At March 31, 2007, approximately 1,697,000 shares of common stock were reserved for future issuance under our ESPP.

For the fiscal years ended March 30, 2008, March 31, 2007 and March 31, 2006, we issued 33,705, 36,832 and 140,620 shares at weighted average prices of $10.07, $12.53 and $11.09, respectively, to the participating employees.

Stock Option Plans

On September 7, 2006, our stockholders ratified the Exar Corporation 2006 Equity Incentive Plan (the “2006 Plan”). The 2006 Plan authorizes 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. Individuals eligible to receive awards under the 2006 Plan include our officers, employees, directors, and certain consultants and advisors. The 2006 Plan allows for performance-based vesting and partial vesting based upon level of performance. At March 30, 2008, there were approximately 4.2 million shares available for future grant.

Upon the merger with Sipex, we assumed options to purchase approximately 2.2 million shares of Sipex common stock (after the application of the exchange ratio in the merger) that had been granted by Sipex under its five option plans: the 1997 Stock Option Plan, 1999 Stock Plan, 2000 Non-Qualified Stock Option Plan, Amended and Restated 2002 Non-Statutory Stock Option Plan and 2006 Equity Incentive Plan. We can grant options or issue shares pursuant to the assumed Sipex plans, but only to former Sipex employees or employees of the combined company hired after the merger. The 1997 Stock Option Plan expired in 2007. At March 30, 2008, there were approximately 0.7 million shares available for future grant under the Sipex plans.

Generally, options under the 2006 Plan are granted with an exercise price of 100% of the fair value of the underlying stock on the date of grant and have a term of seven years, although the 2006 Plan provides that options may be granted with a term of up to ten years. Options generally vest at a rate of 25%, on their anniversary date, over four years. The assumed Sipex plans generally allow for options which vest ratably over five years from the date of grant for options granted before May 2002 and four years for options granted after April 2002. These options expire ten years from the date of grant.

As of March 30, 2008, there were approximately 5.1 million options outstanding under all stock option plans. As of March 31, 2007, there were approximately 5.3 million options outstanding under all stock option plans.

Valuation Assumptions

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

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

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

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

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

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

* We amended our ESPP on April 1, 2006 to permit employees to purchase common stock at a purchase price that is equal to 95% of the fair market value of the common stock on the last trading day of each three-month offering period. The amendment to the employees' discount and the elimination of the look-back period resulted in the ESPP being considered non-compensatory under SFAS 123R.

The aggregate intrinsic values in the table above represented the total pre-tax intrinsic value which was based on the fair value of our common stock of $8.19, $13.24 and $14.28 as of March 30, 2008, March 31, 2007 and March 31, 2006, respectively. These were the values which would have been received by option holders if all option holders exercised their options as of that date.

The total number of in-the-money options vested and exercisable was 0.7 million, 0.8 million and 2.4 million for the fiscal years ended March 30, 2008, March 31, 2007 and March 31, 2006.

Total intrinsic value of options exercised was approximately $1.4 million, $1.7 million and $6.8 million for the fiscal years ended March 30, 2008, March 31, 2007 and March 31, 2006, respectively.

Total cash received related to option exercises was $3.9 million, $14.9 and $10.3 million for the fiscal years ended March 30, 2008, March 31, 2007 and March 31, 2006, respectively. Upon option exercise, we issue shares of common stock.

We recorded a tax benefit of $1.4 million, $0.5 million and $1.6 million related to the option exercises for the fiscal years ended March 30, 2008, March 31, 2007 and March 31, 2006, respectively.

Total unrecognized stock-based compensation cost was $5.0 million at March 30, 2008, which was expected to be recognized over a weighted average period of 2.64 years. Total unrecognized stock-based compensation cost was $5.5 million at March 31, 2007, which was expected to be recognized over a weighted average period of 2.71 years.

Restricted Stock Awards and Units

Restricted Stock Awards (“RSAs”)

During the fiscal year of 2006, we awarded 30,000 shares of restricted stock to our former president and chief executive officer on March 24, 2005 in connection with his employment agreement. The restricted stock vested annually over a period of three years and had a grant date fair value of $13.52. At March 31, 2007, 10,000 shares remained unvested with a remaining contractual life of one year. As a result of his termination in February 2007, the unvested 10,000 shares were canceled thereafter. At March 30, 2008, there were no unvested shares of RSAs.

For each of the fiscal years ended March 31, 2007 and March 31, 2006, stock-based compensation expense was $0.1 million associated with this award. No stock-based compensation expense was recorded for the fiscal year of 2008 as the award was canceled due to the termination of the officer.

Total unrecognized stock-based compensation cost in connection with this restricted stock was approximately $135,000 at March 31, 2007 and there was no unrecognized compensation cost at March 30, 2008 associated with this award.

During fiscal year 2007, we did not grant RSAs to any employees or directors.

During fiscal year 2008, we granted the chairman of our board of directors 10,000 shares of fully vested common stock and recorded approximately $134,000 as stock-based compensation expense in December 2007. During the same period, we granted our former chief executive officer 5,000 shares of fully vested common stock after his three months of service, as per his employment agreement, and recorded approximately $45,000 as stock-based compensation expense.

Restricted Stock Units (“RSUs”)

In the second fiscal quarter of 2007, we began issuing restricted stock units to employees and non-employee directors. Restricted stock units currently granted by us generally vest on the first or third anniversary date from the grant date. Restricted stock units granted under the 2006 Plan are counted against authorized shares available for future issuance on the basis of two shares for every restricted stock unit issued. Prior to vesting, restricted stock units do not have dividend equivalent rights, do not have voting rights and the shares underlying the restricted stock units are not considered issued and outstanding. Shares are issued on the date the restricted stock units vest.

At March 30, 2008, there were 304,933 RSUs outstanding. The unrecognized stock-based compensation cost was $2.5 million at March 30, 2008 and was expected to be recognized as compensation expense over a weighted average period of 1.41 years.

At March 31, 2007, there were approximately 204,918 RSUs outstanding. The unrecognized stock-based compensation cost was $2.7 million at March 31, 2007 and was expected to be recognized as compensation expense over a weighted average period of 2.05 years.

A summary of restricted stock unit transactions was as follows:

(1) Aggregate intrinsic value for RSUs represents the closing price per share of our stock on March 30, 2008 and March 31, 2007, respectively, multiplied by the number of non-vested RSUs expected to vest as of March 30, 2008 and March 31, 2007, respectively.

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 recorded on a straight-line basis, over the vesting period.

During the fiscal year of 2008, we granted approximately 22,000 shares of performance-based RSUs 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 expenses related to these grants for the year ended March 30, 2008. No such grants were made in the fiscal year of 2007.

Total unamortized stock-based compensation expense for our unvested RSUs was $2.4 million at March 30, 2008 and was expected to be recognized as compensation expense over a weighted average period of 1.98 years. Total unamortized stock-based compensation expense for our unvested RSUs was $2.2 million at March 31, 2007 and was expected to be recognized as compensation expense over a weighted average period of 2.0 years.

Stock-Based Compensation Expenses

The following table summarized stock-based compensation expense related to stock options, RSAs and RSUs under FAS 123R for the fiscal years ended March 30, 2008 and March 31, 2007, and stock-based compensation expense related to stock options under APB No. 25 for the fiscal year ended March 31, 2006 (in thousands):

Stock-based compensation expense	$	4,979	$	4,350	$	135

* Prior to the adoption of FAS 123R on April 1, 2006, we accounted for stock-based compensation under Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees (“APB 25”).

At March 30, 2008, there was approximately $33,000 of total unamortized compensation cost capitalized in inventory. At March 31, 2007, there was no unamortized compensation cost capitalized in inventory.

During the fiscal year of 2008, we modified approximately 298,000 stock options 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 from three months as defined by the plan to six months. As a result of the modifications, we recorded additional stock-based compensation expenses of approximately $18,000 during the fiscal year ended March 30, 2008.

During the fiscal year of 2007, we recorded stock-based compensation expense of $0.4 million in connection with modifications of approximately 0.8 million stock options related to the separations of our former chief executive officer and chief financial officer.

No modifications were made during the fiscal year ended March 31, 2006.

During the fiscal year of 2006 in March, our board of directors approved the full acceleration of vesting of all employee stock options, including options held by our executive officers, with exercise prices in excess of $15.05. Such vesting acceleration did not apply to any options held by our non-employee directors. As a result of the decision to fully accelerate the vesting of stock options, as described above, options to purchase approximately 1.1 million shares of our common stock became fully vested and immediately exercisable effective as of March 22, 2006.

FISCAL YEARS ENDED MARCH 30, 2008, MARCH 31, 2007 AND MARCH 31, 2006

Because the accelerated options’ exercise prices were in excess of the market value of our common stock at the time of the acceleration, we believed that the incentive value to our employees of the associated unvested options was minimal. The acceleration eliminated future compensation expense we would otherwise have had to recognize in our statements of operations with respect to these options under FAS 123R. As a result of this action, approximately $4.9 million of stock-based compensation expense, net of taxes, was excluded from stock-based compensation for periods subsequent to fiscal year 2006.

Income Tax

In November 2005, the FASB issued Staff Position No. FAS 123R-3, Transition Election Related to Accounting for Tax Effects of Share-Based Payment Awards (“FAS 123R-3”). FAS 123R-3 provides guidance that establishes the beginning balance of the APIC pool related to the tax effects of employee stock-based compensation, which is available to absorb tax deficiencies recognized subsequent to the adoption of FAS 123R. We elected to adopt the alternative transition method (“short cut method”) in calculating our historical APIC pool of windfall tax benefits in regards to our stock-based compensation. The alternative transition method provides a simplified method to establish the beginning balance of the APIC Pool related to the tax benefits of stock-based compensation expense, and to determine the subsequent impact on the APIC Pool and consolidated statements of cash flows of the tax effects of stock-based compensation awards that are outstanding upon adoption of FAS 123R.

We record our stock-based compensation expense in multiple jurisdictions. In jurisdictions where an income tax deduction is allowed and an income tax benefit is realizable, we have recognized an income tax benefit. In jurisdictions where an income tax deduction is not allowed or where an income tax benefit is not realizable, an income tax benefit has not been recognized.

Pro Forma Information under FAS 123 for Periods Prior to April 1, 2006

Prior to FAS 123R adoption, we accounted for stock-based compensation under Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees (“APB 25”) and accordingly, we recognized compensation expense related to stock options with intrinsic value and accounted for forfeitures as they occurred. The following table provided pro forma disclosures as if we had recorded compensation costs based on the estimated grant date fair value, as defined by the FAS 123, for awards granted under its stock-based compensation plans (in thousands, except per share data):

NOTE 13.    WARRANTS

In connection with the Sipex merger, we assumed warrants 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 30, 2008, there were approximately 280,000 warrants outstanding.

NOTE 14.    LEASE OBLIGATIONS

In connection with the Sipex merger, we assumed a lease financing obligation related to a facility, located at 233 South Hillview Drive in Milpitas, California (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 merger and was included in the “Property, plant and equipment, net” line item on the consolidated balance sheet. In connection 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 $205,000 in fiscal year 2008. There was no depreciation expense in fiscal years 2007 and 2006.

In addition to the Hillview facility, we also have a four-year lease of $5.2 million of engineering design tools (“design tools”) starting December 2007, which are accounted for as a capital lease and recorded in the “Property, plant and equipment, net” line item on the consolidated balance sheet. The related design tools obligation were included in the “Long-term lease financing obligations” line on our consolidated balance sheet. The effective interest rate for the design tools is 7.25%. Amortization on the design tools was recorded over the straight-line method for the remaining useful life and was $322,000 in fiscal year 2008. There was no amortization expense in fiscal years 2007 and 2006.

Future minimum lease payments for our lease financing obligations as of March 30, 2008 were as follows (in thousands):

Fiscal Years	Hillview Facility			Design Tools			Subtotal			Operating Leases
2009	$	1,374		$	684		$	2,058		$	583
2010		1,415			1,450			2,865			314

Long-term lease financing obligation	$	12,966		$	3,413		$	16,379		$	1,260

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.

For fiscal year 2008, interest expense totaled approximately $640,000 and $44,000, respectively, for the Hillview lease financing obligation and design tools, respectively.

NOTE 15.    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. Although the area and extent of the contamination appear to have been defined, the source of the contamination has not been identified. 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 has been shut down during calendar year 2008, for a two-year plume stability evaluation.

In February 2006, we entered into a definitive Master Agreement with Silan, a China-based semiconductor foundry. This transaction was related to the closing of our wafer fabrication operations located in Milpitas, California. Under this agreement, Exar and Silan would work together to enable Silan to manufacture semiconductor wafers using our 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. Once we confirm to Silan that the process qualification wafers and product qualification wafers (under a Wafer Transfer Agreement) conform to its specifications, Silan would commence commercial manufacturing for us. 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 two years beginning January 1, 2007. As of March 30, 2008, several complementary metal oxide semiconductor (“CMOS”) and all bipolar and BiCMOS (bipolar CMOS) product qualifications have been completed to our specifications. The open purchase orders were approximately $1.8 million at March 30, 2008.

Generally, we warrant all of our products against defects in materials and workmanship for a period ranging from ninety days to two 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 approximately $0.3 million at March 30, 2008.

Additionally, our sales agreements indemnify our customers for any expenses or liability resulting from alleged or claimed infringements of any United States letter patents of third parties. However, we are not liable for any collateral, incidental or consequential damages arising out of patent infringement. The terms of these indemnification agreements are perpetual, commencing after execution of the sales agreement or the date indicated on our order acknowledgement. The maximum amount of potential future indemnification is unlimited. However, to date, we have not paid any claims or been required to defend any lawsuits with respect to any such indemnity claim.

NOTE 16.    LEGAL PROCEEDINGS

From time to time, we are involved in various claims, legal actions and complaints arising in the normal course of business. Although the ultimate outcome of the matters discussed below and other matters is not presently determinable, management currently believes that the resolution of all such pending matters will not have a material adverse effect on our financial position, results of operations or liquidity.

Ericsson Wireless Communication, Inc. and Vicor Corporation

On November 16, 2004, Ericsson Wireless Communications, Inc. (now known as Ericsson Inc.) (“Ericsson”) initiated a lawsuit against us in San Diego County Superior Court. In its Third Amended Complaint, Ericsson asserted causes of action against us for negligence, strict product liability, and unfair competition. Ericsson sought monetary damages and unspecified injunctive relief. Based on discovery responses, Ericsson claimed that its damages exceeded $1 billion. The case is based on Ericsson’s purchase of allegedly defective products from Vicor Corporation, our former customer to whom we sold untested, semi-custom wafers. We disputed the allegations in Ericsson’s Third Amended Complaint, believed that we had meritorious defenses, and defended the lawsuit vigorously. On December 1, 2006, we entered into a Settlement Agreement with Ericsson, Inc. to resolve the claims asserted by Ericsson. Based on further events in the case, our total liability to Ericsson under the Settlement Agreement was $500,000, which was paid by our insurance carriers. Following payment, Ericsson dismissed its claims against us with prejudice.

On April 5, 2005, Vicor Corporation (“Vicor”) filed a cross-complaint against us in San Diego County Superior Court. Vicor alleged, among other things, that we sold it integrated circuits that were defective and failed to meet agreed-upon specifications, and that we intentionally concealed material facts regarding the specifications of the integrated circuits that Vicor alleges it bought from us. Vicor alleged that it is entitled to indemnification from us for the damages that Vicor paid to Ericsson as a result of the causes of action asserted by Ericsson against Vicor. In the cross-complaint, Vicor asserted various contract, tort, and indemnity based causes of action against us. On May 9, 2005, we filed a demurrer to all but one of Vicor’s causes of action against us, which the San Diego Superior Court sustained without leave to amend on June 17, 2005, except for the claims for implied contractual indemnity and equitable indemnity. We answered those causes of action on July 5, 2005. We disputed the allegations in Vicor’s cross-complaint, believed that we had meritorious defenses, and defended the lawsuit vigorously.

On December 1, 2006, we entered into a Settlement Agreement with Ericsson, Inc. We filed a motion on December 20, 2006 for an order finding the Settlement Agreement that we entered with Ericsson was in good faith. On January 22, 2007, the Court entered an order finding that we entered into the Settlement Agreement in good faith. The result of the finding of good faith was that Vicor’s indemnity claims were subject to dismissal. On February 13, 2007, Vicor filed a petition for writ of mandate with the California Court of Appeal challenging the good faith finding, which the Court of Appeal summarily denied on February 28, 2007. The San Diego Superior Court dismissed Vicor’s indemnity claims and entered judgment in our favor on July 10, 2007. After entering judgment, the San Diego Superior Court awarded us costs against Vicor in the amount of $84,405 and monetary sanctions against Vicor in the amount of $44,266.91. Vicor filed a notice of appeal on September 6, 2007, and Vicor filed its opening brief on March 27, 2008. Exar’s responding brief is not yet due, and oral argument has not yet been set.

On March 4, 2005, we filed a complaint in Santa Clara County Superior Court against Vicor. In the complaint, we sought a declaration regarding the respective rights and obligations, including warranty and indemnity rights and obligations, under the written contracts between us and Vicor for the sale of untested, semi-custom wafers. In

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)

FISCAL YEARS ENDED MARCH 30, 2008, MARCH 31, 2007 AND MARCH 31, 2006

addition, we sought a declaration that we were not responsible for any damages that Vicor must pay to Ericsson or any other customer of Vicor arising from claims that Vicor sold allegedly defective products.

On March 17, 2005, Vicor filed a cross-complaint against us and Rohm Device USA, LLC and Rohm Co., Ltd, the owners and operators of the foundry which supplied the untested, semi-custom wafers that we sold to Vicor. In the cross-complaint, Vicor asserted allegations similar to those in its cross-complaint in the Ericsson San Diego County action discussed above, and also alleged that it is entitled to indemnification from us for any damages that Vicor must pay to Ericsson or other Vicor customers that may be make claims against Vicor. In the cross-complaint, Vicor asserted various contract, tort, and indemnity based causes of action against us. On May 23, 2005, we filed a demurrer to each cause of action in Vicor’s cross-complaint, and on July 15, 2005, the Santa Clara County Superior Court sustained our demurrer to each of the causes of action. The Court granted Vicor leave to amend the cross-complaint to assert a cause of action for declaratory relief only. On August 1, 2005, Vicor filed its amended cross-complaint seeking a declaration of the parties’ respective rights and obligations, including warranty and indemnity rights, under the alleged contracts between us and Vicor for the sale of untested, semi-custom wafers. In addition, Vicor sought a declaration that we were obligated to indemnify it for any damages resulting from claims brought against Vicor by its customers. Vicor’s amended cross-complaint does not seek damages. We answered Vicor’s amended cross-complaint on September 2, 2005. On April 10, 2006, Vicor moved to have the San Diego County action transferred to Santa Clara County and coordinated with the action in Santa Clara County, but the Santa Clara County Court deferred deciding Vicor’s motion until the Court in the San Diego County action could rule on a similar motion pending in that action brought by Ericsson, which was granted. This resulted in the Santa Clara Action being transferred to San Diego for coordination with the Ericsson San Diego County action. No trial date has been set. We do not believe that the litigation will have a material impact on our financial condition, results of operations, or liquidity.

DiPietro v. Sipex

In April 2003, Plaintiff Frank DiPietro (former chief financial officer of Sipex Corp.) brought an action for breach of contract against Sipex in the Middlesex Superior Court in the state of Massachusetts. Mr. DiPietro was seeking approximately $800,000 in severance benefits. Sipex counterclaimed for approximately $150,000, which it was owed under a promissory note signed by Mr. DiPietro. In August 2004, Sipex filed two motions for summary judgment (one for Mr. DiPietro’s claims against it and one for its counterclaim against Mr. DiPietro). In June 2005, the Middlesex Superior Court granted both Sipex’s Motions for Summary Judgment. Soon thereafter, Mr. DiPietro filed a notice of appeal. Sipex then filed motions for costs and pre-judgment interest. Sipex was successful in its motion for prejudgment interest and it was successful in requiring Mr. DiPietro to pay over $900 in deposition costs.

On June 21, 2006, Mr. DiPietro served Sipex with his appeal brief. On July 20, 2006, Sipex served its Opposition and Mr. DiPietro’s Reply Brief was served on August 3, 2006. On December 12, 2006, the Appeals Court heard arguments in DiPietro v. Sipex and asked for a letter clarifying a legal issue that Sipex provided on December 28, 2006. On January 12, 2007, Mr. DiPietro sent a letter responding to Sipex’s letter.

On May 14, 2007, the Appeals Court issued its decision reversing the Superior Court’s grant of summary judgment and remanding the case for further proceedings. Sipex immediately filed a motion for enlargement of time to file a Petition for Rehearing and an Application for Further Appellate Review. Sipex’s Petition for Rehearing was filed on June 13, 2007, in the Massachusetts Appeals Court and its Application for Further Appellate Review was filed on June 28, 2007, in the Massachusetts Supreme Judicial Court. Thereafter, on July 9, 2007, DiPietro filed its Opposition to Sipex’s Application for Further Appellate Review and on July 18, 2007, filed his Response to Sipex’s Petition for Rehearing. In early September 2007, the Appeals Court amended its decision to clarify issues addressed in Sipex’s Petition for Rehearing.

On October 31, 2007, Sipex’s Application for Further Appellate Review was denied. The case was remanded to Superior Court and will proceed. A pretrial conference is scheduled for June 16, 2008.

Cypress v. Sipex, Exar and Ralph Schmitt

On October 12, 2007, Cypress Semiconductor Corporation (“Cypress”) filed an action against Sipex Corporation (“Sipex”), Exar Corporation (“Exar”), Ralph Schmitt and Does 1 through 50 in the Superior Court of the State of California, County of Santa Clara, Cypress Semiconductor Corp. v. Sipex Corp., et al., Case No. 1-07-CV096311, alleging claims for: (1) misappropriation of trade secrets; (2) violation of the Computer Fraud and Abuse Act, 18 U.S.C. §1030; (3) unfair competition under Cal. Bus. & Prof. Code §§17200 et seq.; (4) tortious interference with contract; (5) interference with actual and prospective economic advantage; (6) breach of fiduciary duty and breach of the duty of loyalty; (7) inducement of breach of fiduciary duty; (8) breach of written contract; (9) breach of the covenant of good faith and fair dealing; (10) conversion; and (11) unjust enrichment. The second, sixth, eighth and ninth causes of action are alleged against Mr. Schmitt only. Mr. Schmitt was Chief Executive Officer and President and a member of the board of directors of Exar from August 25, 2007 to December 6, 2007. Prior to Exar’s merger with Sipex, he was Chief Executive Officer and a member of the board of directors of Sipex. Exar filed an answer to the complaint on November 13, 2007. The case was removed to federal court on November 14, 2007, Cypress Semiconductor Corp. v. Sipex Corp., et al., United States District Court, Northern District of California, Case No. C 07-05778 JF. The parties exchanged Initial Disclosures pursuant to Federal Rules of Civil Procedure, Rule 26(a)(1) on March 7, 2008. A Case Management Conference was held on March 14, 2008 before the Honorable Jeremy Fogel. At the Case Management Conference, Judge Fogel ordered that discovery be stayed for 60 days to allow the parties the opportunity to discuss settlement. A Settlement Conference took place before Magistrate Judge Seeborg on May 13, 2008 which resulted in a settlement of the case. The terms of the settlement are confidential and the settlement amount was not material to our financial condition, results of operations or liquidity. On May 28, 2008, Judge Fogel issued a conditional Order of Dismissal of the case with prejudice.

approximately $4.2 million of our foreign subsidiaries are considered to be indefinitely reinvested and accordingly, no provisions 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 the various foreign countries.

As of March 30, 2008, our federal and state net operating loss carryforwards for income tax purposes were approximately $226.1 million and $88.0 million, respectively. If not utilized, $6.0 million of the federal net operating loss carryforwards will expire in 2009, and $3.0 million of the state net operating losses will begin to expire in 2011. Additionally, we have capital loss carryforwards of approximately $39.6 million, which will expire in 2010 if not utilized.

As of March 30, 2008, our federal and state tax credit carryforwards were $7.5 million and $9.3 million, respectively. The federal and state credits will begin to expire in 2012 and 2009, 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 $7.6 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. In addition, we have approximately $70.8 million of acquired entity deferred tax assets that will be adjusted first to the extent of goodwill, then to the extent of identifiable intangible assets and lastly as a reduction in the income tax provision.

Uncertain Income Tax Benefits

Effective April 1, 2007, we adopted Financial Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes – an interpretation of FASB Statement No. 109 (“FIN 48”). FIN 48 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.

The cumulative effect of adopting FIN 48 was a decrease in the liability for uncertain tax positions and an increase of $0.2 million to the April 1, 2007 opening retained earnings balance. Upon adoption of FIN 48, the liability for uncertain tax positions at April 1, 2007 was $0.8 million. Consistent with the provisions of FIN 48, we reclassified $0.8 million of income tax liabilities from current to non-current liabilities because payment of cash is not anticipated within one year of the balance sheet date. In addition, we decreased current taxes payable and deferred tax assets by $3.5 million for unrecognized tax benefits which serve to reduce net operating loss and tax credit carryforwards.

The total amount of gross unrecognized tax benefits as of the April 1, 2007 adoption date of FIN 48 was $7.7 million. The unrecognized tax benefits increased by $1.7 million during the fiscal year ended March 30, 2008 to $9.4 million. If recognized, all of these unrecognized tax benefits would be recorded as a reduction of future income tax provision before consideration of changes in valuation allowance.

The reconciliation of the unrecognized gross tax benefit of $9.4 million is as follows: $0.8 million in income taxes payable, non-current, and $8.6 million as a reduction to deferred tax assets. The total amount of unrecognized tax benefit (net of federal benefit), if recognized would affect the effective rate is $7.8 million.

Estimated interest and penalties related to the underpayment of income taxes were classified as a component of the provision for income taxes in the consolidated statement of operations. Accrued interest and penalties were $0.1 million and $0.2 million as of April 1, 2007 and March 30, 2008, respectively.

Our only major tax jurisdictions are the United States federal and various states. The fiscal years 1997 through 2007 remain open and subject to examinations by the appropriate governmental agencies in the United States with fiscal years 2000 through 2007 open to audits in certain of our state jurisdictions.

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. 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 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 communications 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 2008.

Inherent Limitations on the Effectiveness of Disclosure Controls

Our management, including the CEO and CFO, does not expect that the 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 30, 2008 based on the framework established by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework . Based on this assessment, management concluded that, as of March 30, 2008, our internal control over financial reporting was effective. The independent registered public accounting firm, PricewaterhouseCoopers LLP, has issued an attestation report on our internal control over financial reporting. The report on the audit of internal control over financial reporting appears on page 58 of this Annual Report on Form 10-K.

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

101

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.

Changes in Internal Control over Financial Reporting

In August 2007, we acquired Sipex Corporation. Sipex operated under its own set of systems and internal controls. We have completed incorporating Sipex’s processes into our own systems and control environment at March 30, 2008.

In addition, in conjunction with the Sipex merger, we reassessed our ability to estimate returns and allowances and consequently, changed the revenue recognition used for sales to our two primary distributors, Future Electronics Inc. and Nu Horizons Electronics Corp., from sell-in basis to sell-through basis. We modified and refined our internal control procedures related to our revenue recognition. We believe that we have taken the necessary steps to monitor and maintain appropriate internal control over financial reporting during this change.

There was no other change in our internal control over financial reporting that occurred during the fourth fiscal quarter of 2008 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
